Indah K Murni, Dian C Sulistyoningrum, Rina Susilowati, Madarina Julia, Kacie M Dickinson
Background and objective: Poor diets, characterized by excess fat, sugar and sodium intakes, are considered to be one of the most important modifiable risk factors for cardiovascular disease. Diet patterns and intakes during adolescence may persist into adulthood and impact on risk for chronic disease later in life. We aimed to evaluate the dietary intake of obese adolescents and its relationship to cardiometabolic health including lipid status and glycemic control. Methods and study design: This was a cross-sectional study of obese children aged 15 to < 18 years in Yogyakarta, Indonesia. All children had a medical history performed including a physical examination and fasting blood sample. Dietary intake was assessed using a semi-quantitative recall food frequency questionnaire. Multivariable linear regression model was performed to determine the relationship between dietary intakes and cardiovascular disease risks and to adjust for potential confounders. Results: Of 179 adolescents, 101 (57.4%) were male and median age was 16.4 (15.0–17.9) years. The majority of adolescents (98%) had inadequate intake of fibre and exceeded intakes of total fat (65%) and total sugar (36%). There was statistically significant correlation found in the multivariable linear regression analysis between fibre intake and HDL cholesterol after adjusting for potential confounders (β = 0.165; p = 0.033). Conclusions: This study demonstrates that there is a high proportion of obese Indonesian adolescents with poor dietary intakes. There was relationship observed between intake of nutrients of concern (fibre) and cardiometabolic risk factor among this sample of obese adolescents. Future research should examine overall dietary patterns in more detail among this population to elucidate the role of poor diet intakes in development of cardiovascular disease risk factors in young people transitioning into adulthood.

Nasopharyngeal carcinoma (NPC) is endemic cancer in Southeast Asia with a relatively poor prognosis. Chemoradiotherapy is a primary treatment that advantages certain patients, particularly in the early stages. New predictive and prognostic biomarkers are required to guide and select the best treatment.
To evaluate the circulation expression profile of microRNAs (miRNAs) associated with responses to chemoradiotherapy in nasopharyngeal carcinoma.
Peripheral blood from 17 patients was collected before and after chemotherapy and radiotherapy. Differential expression circulating miRNAs were analyzed using microRNA Cancer Panels and were compared among patients with complete responses. Differential expression analysis using GenEx 7 Multid, statistic represented by GraphPad Prism 9. Alterations mechanism signaling pathways and biological function using IPA (Ingenuity Pathways Analysis).
Using microRNAs Cancer Plate consisting of 116 miRNAs, we identified ten circulating miRNAs that were differentially expressed in NPC patients after chemoradiotherapy. Unsupervised clustering and confirmation using qRT-PCR showed that miR-483-5p, miR-584-5p, miR-122-5p, miR-7-5p, miR-150-5p were overexpressed and miRNA are miR-421, miR-133a-3p, miR-18a-5p, miR-106b-3p, miR-339-5p were significantly downregulated after chemoradiotherapy (p < 0.0001). In addition, ROC analysis through AUC (Area Under Curve) with 99% confidence interval (CI) p value < 0.0001. Gene enrichment analysis of microRNAs and the targeted proteins revealed that the main involved pathways for chemoradiotherapy in NPC were cell death and survival signaling pathways.
qPCR profiling in circulating blood compared before and after chemoradiotherapy in nasopharyngeal carcinoma can identify pathways involved in treatment responses. miR-483-5p, miR-584-5p, miR-122-5p, miR-7-5p, miR-150-5p, miR-421, miR-133a-3p, miR-18a-5p, miR-106b-3p, miR-339-5p are differentially regulated after chemoradiotherapy in NPC.

Suci Widhiati, Shinta Trilaksmi Dewi, Retno Danarti, Hardyanto Soebono, Yulia Eka Irmawati, Monika Puspitasari, Niken Trisnowati, Tri Wibawa, Dewajani Purnomosari, Yohanes Widodo Wirohadidjojo
Background: Autologous non-cultured cell (ANCC) spray has been used to treat burns, chronic wounds, and vitiligo, but its use in junctional epidermolysis bullosa (JEB) has not been published previously. Chronic wounds in JEB are caused by mutations of laminin 332 (L322), whose function is to attach and act as a glue in the basal membrane. It is proposed that ANCC applications can provide keratinocytes and fibroblasts required to improve epithelization and spontaneously correct revertant keratinocytes in the wound area.
Purpose: To develop a modified procedure of ANCC spray and improve epithelization using silver sulfadiazine covered with plastic wrap to treat chronic wounds of JEB.
Patients and Methods: Shave excision of the donor site was performed on a 19-year-old girl with JEB. The ANCC spray was prepared and applied to the chronic wound, which was then covered with silver sulfadiazine occluded with plastic wrap.
Results: Following the ANCC spray application, epithelization was successfully initiated. Unfortunately, the wounds recurred after four months of follow-up.
Conclusion: The modified application method of ANCC spray provides a good alternative to treat chronic wounds in JEB.
Keywords: revertant mosaicism, silver-sulfadiazine, plastic wrap, chronic wound, junctional epidermolysis bullosa

The long-term antibody response to the novel SARS-CoV-2 in infected patients and their residential neighborhood remains unknown in Indonesia. This information will provide insights into the antibody kinetics over a relatively long period as well as transmission risk factors in the community. We aim to prospectively observe and determine the kinetics of the anti-SARS-CoV-2 antibody for 2 years after infection in relation to disease severity and to determine the risk and protective factors of SARS CoV-2 infections in the community. A cohort of RT-PCR confirmed SARS-CoV-2 patients (case) will be prospectively followed for 2 years and will be compared to a control population. The control group comprises SARS-CoV-2 non-infected people who live within a one-kilometer radius from the corresponding case (location matching). This study will recruit at least 165 patients and 495 controls. Demographics, community variables, behavioral characteristics, and relevant clinical data will be collected. Serum samples taken at various time points will be tested for IgM anti-Spike protein of SARS-CoV-2 and IgG anti-Spike RBD of SARS-CoV-2 by using Chemiluminescent Microparticle Immunoassay (CMIA) method. The Kaplan-Meier method will be used to calculate cumulative seroconversion rates, and their association with disease severity will be estimated by logistic regression. The risk and protective factors associated with the SARS-CoV-2 infection will be determined using conditional (matched) logistic regression and presented as an odds ratio and 95% confidence interval.

Tirta Wardana, Risky Oktriani, Cita Herawati Murjayanto, Denise Utami Putri, Sumadi Lukman Anwar, Teguh Aryandono, Sofia Mubarika Haryana
Background and aim: Nasopharyngeal Carcinoma (NPC) is an upper respiratory tract cancer prevalent in Southeast Asia and related to chronic EBV infection. microRNAs (miRNAs) regulate gene expression implicated in NPC’s carcinogenesis . However, this circulating RNA molecule’s role and clinical utility remain unknown. Therefore, this study examined the circulation of miRNAs and their association with clinical data.
Methods: 160 plasma samples of NPC and 80 non-tumor samples were extracted to evaluate and validate the gene expressions. Quantification expression was performed using relative quantification of qPCR analysis level expression methods. The intrinsic cellular roles involving biological signaling in NPC’s oncogenesis using Ingenuity Pathways Analysis (IPA) were also used.
Results: The results of the quantification significance profiling of NPC samples revealed decreased miR-29c-3p (fold change 1.16; p<0.05) and increased 195-5p expression (fold change 1.157; p<0.05). Furthermore, the validation of hsa-miR-29c-3p expression on plasma NPC with known tumor vs non-tumor and significant changes was also performed using a fold change of 4.45 (medians of 31.45±1.868 and 24.96±1.872, respectively; p<0.0005). miR-29c had a 2.14 fold change correlated with T primary status with a median of 31.99±1.319 and 31.35±2.412, respectively (p<0.05). Stage status with fold change 1.99 also had median levels of 31.98±1.105 and 31.21±2.355, respectively (p-value <0.05). Furthermore, the node's status for the lower expression of miR-29c with fold change 1.17 had median levels of 32.78±2.221 and 31.33±1.689, respectively (p-value of 0.7). Bioinformatics analysis established the roles and functions of miR-29 in NPC progression, cell death and survival, cellular development, cellular function, and cell maintenance by inhibiting COL4A, PI3K, VEGFA, JUN, and CDK6. Conclusion: Overall, we conclude that decreased miR-29c expression is associated with poor clinical status and might inhibit NPC’s five target genes.

Awal Prasetyo, Udadi Sadhana, Dewi K Paramita, Sofia Mubarika Haryana, Bambang Hariwiyanto, Soenarto Sastrowijoto, Totok Utoro
BACKGROUND: The risk-combination of genetic or familial history, environmental risk factors, and EBV infection might cause nasopharyngeal carcinogenesis. The serum antibody for EBV IgA, namely, EBNA1+VCA-p18 has a good sensitivity as an early diagnostic test for nasopharyngeal carcinoma (NPC).
AIM: This study aims to determine the correlation between risk factors and histopathological typing of NPC and also the correlation between the IgA [EBNA-1 + VCA p-18] ELISA and histologic type.
METHODS: A cross-sectional method was used on 108 NPC patients which filled a questionnaire through an in-depth interview on the family condition to cancer, habit/lifestyle, and environmental risks. A total of 47 subjects were willing to donate blood samples for IgA [EBNA1 + VCA p-18] ELISA. Furthermore, Kendall’s tau-b (τ) correlation test was performed on NPC keratin type (WHO-1) and non-keratin (WHO-2 and 3).
RESULTS: The results showed that the family history of non-keratinized NPC was associated with NPC WHO-3 as demonstrated by τ = 0.473, as well as salt-eating with τ = 0.334, smoked/grilled fish/meat eating τ = 0.205, instant noodle-eating τ = 0.356, consuming canned/packaged canned foods τ = 0.240, and flavored food eating habits τ = 0.364, along with passive smoking τ = 0.377, and chronic nasopharyngeal infection τ = 0.530. The IgA titers, namely, [EBNA1 + VCA p-18] ELISA for non-keratin type NPC was greater than the keratin type; however, it was not related to WHO-3 NPC as indicated by τ = 0.376, and p = 0.011 put this underlying before however.
CONCLUSIONS: The positivity of IgA [EBNA-1 + VCA p-18] ELISA does not correlate with the non-keratin type histologic NPC, family history, as well as salt-eating, instant noodle, and flavored food eating habits, along with passive smoking and nasopharyngeal infection.

Microscopic examination is the backbone of malaria diagnosis and treatment evaluation in Indonesia. This test has limited ability to detect malaria at low parasite density. Inversely, nested polymerase chain reaction (PCR) can detect parasites at a density below the microscopic examination’s detection limit. The objective of this study is to compare microscopic and PCR results when being used to identify malaria in suspected patients and patients who underwent dihydroartemisinin–piperaquine (DHP) therapy in the last 3–8 weeks with or without symptoms in Sumba Barat Daya, Nusa Tenggara Timur, Indonesia. Recruitment was conducted between April 2019 and February 2020. Blood samples were then taken for microscopic and PCR examinations. Participants (n = 409) were divided into three groups: suspected malaria (42.5%), post-DHP therapy with fever (4.9%), and post-DHP therapy without fever (52.6%). Microscopic examination found five cases of P. falciparum + P. vivax infection, while PCR found 346 cases. All microscopic examinations turned negative in the post-DHP-therapy group. Conversely, PCR result from the same group yielded 29 negative results. Overall, our study showed that microscopic examination and PCR generated different results in detecting Plasmodium species, especially in patients with mixed infection and in patients who recently underwent DHP therapy.

Biobanking is a relatively newly recognized and innovative branch of science, which includes the collection of samples and associated data from hospitals, diagnostic centers, and voluntary donations for biomedical and environmental research. It involves diverse stakeholders at the junction of society, science, ethics, law, and politics. A key element in the success of a biobank is the trust and support of public donors, clinicians, and scientists. To achieve trust, it is important to implement strategies that can increase biobank awareness in common people, and different types of communities. Biobank laws and regulations and transparent governance by the biobanks are also crucial to achieving public trust.
Keywords: awareness; donors’ trust in a biobanking; transparency; trust.

Mutiara Putri, Anggoro Budi Hartopo, Maria Patricia Inggriani, Jajah Fachiroh, Fatwa Sari Tetra Dewi
Background: Hypertension is known as independent factor in correlation with coronary artery disease (CAD) and play important part in atherosclerotic process. In an animal model with hypertension which endothelin-1 play as a vasoconstrictor, there was overexpression of endothelin-1 in the vessel walls. This overexpression suggests a role of endothelin-1 in hypertension patient, especially among CAD.
Material and methods: This was a cross-sectional study. A total 226 subjects were analysed, consisted of 127 subjects with CAD and 99 healthy population. The CAD subjects were patients underwent elective coronary angiography with significant CAD lesion. The healthy population were respondents of Sleman-HDSS survey (year 2019). Hypertensive subjects were defined those with history of hypertension from anamnesis. Diabetic subjects were excluded. The endothelin-1 was measured from peripheral serum samples by ELISA method. The comparative analysis was performed with Mann-Whitney test and the correlation was performed with Spearman correlation test.
Results: Mean serum endothelin-1 level was 2.1±1.2 pg/mL in hipertensive and 2.6±1.6 pg/mL in normotensive (p=0.063) among CAD subjects. Among healthy population, mean serum endothelin-1 level was 1.7±0.7 pg/mL in hypertensive and 1.8±0.8 pg/mL) in normotensive, (p=0.675). In addition, Spearman correlation between serum endothelin-1 and systolic blood pressure showed correlation coefficient —0.045 (p = 0.543) in CAD subjects and -0.165 (p=0.069) in healthy population which indicated inverse correlation between those parameters in both populations.
Conclusion: Serum endothelin-1 level did not differ significantly based on hypertensive status both in CAD and healthy population. There was a tendency toward decreased serum endothelin-1 level in hypertensive subjects.
Preparation of the “Lexique” for ISBER Best Practices 4th Edition for Biobankers in Indo-Pacific Rim Region
Birendra Kumar Yadav, Hanh Vu, Jajah Fachiroh, Tatsuaki Tsuruyama, Wayne Ng, Koh Furuta
Statement of the Problem: Several standards and guidelines for biobanks or biorepositories have been published by various parties (e.g., the International Society for Biological and Environmental Repositore [ISBER] and the International Organization for Standardization [ISO]). These documents are invaluable for improving the routine practices of the biobanks but the implementation has proven to be challenging for those biobanks from the non-English regions because these resources are mostly written in English.
Proposed Solution: The World Health Organization (WHO) has recently published the International Classification of Diseases 11th Revision (ICD-11) along with a translation tool (lexique) for potential users. This has inspired us to make a similar contribution in the biobanking field. All the regional ambassadors (RAs) and director-at-large (DAL) in the Indo-Pacific Rim (IPR) region worked together to produce a similar lexique for potential users of ISBER’s Best Practices (BPs) 4th edition. A lexique with languages of Hindi, Indonesian, Vietnamese, and Japanese has been prepared.
Conclusions: This lexique is a comparison table between various languages and is expandable to other languages. In addition, this lexique will be a good tool for understanding the ISBER BPs 4th edition.
Keywords: ISO 20387; best practice; lexique; translation.

Astri Ferdiana, Jajah Fachiroh, Dyah Ayu Mira Oktarina, Astrid Irwanto, Caroline Mahendra, Sri Awalia Febriana, Hardyanto Soebono
Background: Allopurinol is the most commonly used drug for the treatment of gout arthritis. However, the use of allopurinol is associated with severe cutaneous adverse reactions (SCARs) and life-threatening immune-mediated reactions that include Stevens-Johnson syndrome (SJS). SJS induced by allopurinol is strongly linked with the presence of HLA-B*58:01 in the Asian population. Such a study has not been conducted in Indonesia. We present two cases with clinical diagnosis of SJS. These patients had Javanese ethnicity, for which evidence on the genetic predisposition of allopurinol-induced SJS/TEN had not been established. Testing for the presence of the HLA-B∗58:01 allele was positive in both cases. Our case report confirms findings from studies in Asian countries that link HLA-B*58:01 and allopurinol-induced SJS/TEN. A larger study is needed to elicit evidence that the HLA-B*58:01 allele can potentially be used as a genetic marker for allopurinol-induced SCARs among different ethnicities in Indonesia.
Keywords: HLA-B*58:01; adverse drug reaction; allopurinol; pharmacogenetics; severe cutaneous adverse reactions; stevens-johnson syndrome.

Anggi Laksmita Dewi, Dewi Kartikawati Paramita, Jajah Fachiroh
Rs1948 A>G is a single nucleotide variation (SNV) in the 3’‐UTR of CHRNB4. Genotyping the synonymous CHRNB4 rs1948 may be useful in identifying a lung cancer susceptibility gene. The study aimed to develop a simple and easy tetra‐primer amplification refractory mutation system (ARMS PCR) for CHRNB4 rs1948. The following steps were taken to optimize tetra‐primer ARMS PCR: 1) determining the gene sequence and position of a single mutation; 2) developing outer and inner primers; 3) amplification of target gene fragments via PCR using an outer primer; 4) genotyping PCR product using Sanger sequencing; 5) determining the optimal annealing temperature and PCR cycle; 6) determining optimal outer and inner primer ratio; and 7) testing the reproducibility of the PCR program and final validation with Sanger sequencing. Genotype (PCR result) was visualized with 3% agarose gel electrophoresis. Optimum condition was determined as annealing temperature of 64.8 ºC and 35 cycles, outer and inner primer ratio of 1:6, and DNA volume of 3 μL. Sanger sequencing confirmed the results of the tetra‐primer ARMS PCR and it was shown that ARMS PCR was able to identify three different variants of CHRNB4 rs1948.

Sandy Nur Vania Putri, Aditya Rifqi Fauzi, Dewi Kartikawati Paramita, Ishandono Dachlan, Rosadi Seswandhana
Background Traumatic brain injury (TBI) is one of the leading causes of death and disability worldwide. In various combinations, a high frequency of facial bone fractures has been reported. However, the results are still conflicting. Methods We retrospectively reviewed medical records of patients with maxillofacial trauma who were admitted to Dr. Sardjito Hospital, Yogyakarta, Indonesia, between January 2016 and December 2017. Results A total of 70 patients with maxillofacial trauma were involved (57 males and 13 females, 18–65 years). Moreover, most of them were 18–25-year-old males (34.3%). The average patient age was 35.5 ± 14 years. No significant association was found between the sex and age group of the patient (p = 0.774). Motorcycle accident was the most frequent cause of maxillofacial fractures (84%) with midfacial and multiple maxillofacial fractures being the most frequent types found in patients (40% and 40%, respectively). The most common facial fracture was in the zygomatic bone (28%) and most cases showed mild facial injury (81%). A significant association was found between the Glasgow Coma Scale (GCS) and types of
traumatic brain injury (TBI) (p = 0.031). However, when GCS was compared with facial injury, no statistically significant level was reached and its correlation was low (p = 0.267, r = 0.134). Conclusions There was a significant association between types of traumatic brain injury with head injury severity. However, we found no correlation between head injury severity and facial injury severity. To explain and validate our results, further multicenter studies with a larger sample size are required.
Level of evidence: Level IV, Risk/Prognostic.

Several types of vaccines have been developed to prevent the coronavirus disease 2019 (COVID-19). It is important to understand whether demographic and clinical variables affect the effectiveness of various types of vaccines. This study analysed the association between demographic/clinical factors, antibody response and vaccine effectiveness in healthcare workers vaccinated with inactivated virus. We enrolled 101 healthcare workers who received two doses of inactivated viral vaccine (CoronaVac). Blood samples were analysed at 1, 3, and 5 months after the second dose of vaccination. Data regarding demographic characteristics, medical histories, and clinical parameters were collected by interview and medical examination. In a separate retrospective study, we analysed the incidence of vaccine breakthrough infection on 2714 healthcare workers who received two doses of inactivated viral vaccine. Medical histories and demographic data were collected using a structured self-reported questionnaire. We found that antibody titres markedly increased at 1 month after vaccination but gradually decreased at 3-5 months post-vaccination. We observed a significant association between age (≥40 years) and antibody level, whereas sex and body mass index (BMI) exhibited no effect on antibody titres. Amongst clinical variables analysed, high blood pressure and history of hypertension were significantly correlated with lower antibody titres. Consistently, we found a significant association in the retrospective study between hypertension and the incidence of breakthrough infection. In conclusion, our results showed that hypertension is associated with lower antibody titres and breakthrough infection following COVID-19 vaccination. Thus, blood pressure control might be important to improve the efficacy of inactivated virus vaccine.

Objective: This study aimed to investigate the association between intra-tumoral and stromal VDR expressions with molecular subtypes and clinicopathological factors. Methods: A total of 75 formalin-fixed paraffin embedded tissue samples were stained using immunohistochemical methods. The VDR expressions were measured by counting brown-stained nuclei in intra-tumoral and stromal areas. The association of VDR expression with molecular subtypes and clinopathological factors was examined. Statistical analysis was performed by chi square tests.
High intra-tumoral VDR expression was found in carcinomas with luminal molecular subtypes (p=0.039) and low histological degrees (p=0.035). High VDR expression in the stroma was found in breast carcinomas with large tumor sizes. Conclusions: High intra-tumoral VDR expression is found in breast carcinomas with luminal subtypes and low histological grade (I/II). Both factors are known to have a good prognosis. These findings further strengthen the function of VDR as anti-tumorigenesis.

Indah K. Murni, Dian C. Sulistyoningrum, Rina Susilowati, Madarina Julia, and Kacie M. Dickinson
Background and objective: Poor diets, characterized by excess fat, sugar and sodium intakes, are considered to be one of the most important modifiable risk factors for cardiovascular disease. Diet patterns and intakes during adoles-cence may persist into adulthood and impact on risk for chronic disease later in life. We aimed to evaluate the dietary intake of obese adolescents and its relationship to cardiometabolic health including lipid status and glycemic control. Methods and study design: This was a cross-sectional study of obese children aged 15 to < 18 years in Yogyakarta, Indonesia. All children had a medical history performed including a physical examination and fasting blood sample. Dietary intake was assessed using a semi-quantitative recall food frequency questionnaire. Multivariable linear regression model was performed to determine the relationship between dietary intakes and cardiovascular disease risks and to adjust for potential confounders. Results: Of 179 adolescents, 101 (57.4%) were male and median age was 16.4 (15.0–17.9) years. The majority of ado-lescents (98%) had inadequate intake of fibre and exceeded intakes of total fat (65%) and total sugar (36%). There was statistically significant correlation found in the multivariable linear regression analysis between fibre intake and HDL cholesterol after adjusting for potential confounders (β = 0.165; p = 0.033). Conclusions: This study demonstrates that there is a high proportion of obese Indonesian adolescents with poor dietary intakes. There was relationship observed between intake of nutrients of concern (fibre) and cardiometabolic risk factor among this sample of obese adolescents. Future research should examine overall dietary patterns in more detail among this population to elucidate the role of poor diet intakes in development of cardiovascular disease risk factors in young people transitioning into adulthood.

Growing evidence shows that viral co-infection is found repeatedly in patients with Coronavirus Disease–2019 (COVID-19). This is the first report of SARS-CoV-2 co-infection with viral respiratory pathogens in Indonesia.
Over a one month period of April to May 2020, SARS-CoV-2 positive nasopharyngeal swabs in our COVID-19 referral laboratory in Yogyakarta, Indonesia, were tested for viral respiratory pathogens by real-time, reverse transcription polymerase chain reaction (RT-PCR). Proportion of co-infection reported in percentage.
Fifty-nine samples were positive for other viral respiratory pathogens among a total of 125 samples. Influenza A virus was detected in 32 samples, Influenza B in 16 samples, Human metapneumovirus in 1 sample, and adenovirus in 10 samples. We did not detect any co-infection with respiratory syncytial virus. Nine (7.2%) patients had co-infection with more than two viruses.
Viral co-infection with SARS-CoV-2 is common. These results will provide a helpful reference for diagnosis and clinical treatment of patients with COVID-19.

Local administration of attenuated mycobacterium has been used as a cancer treatment adjuvant to re-boost patient immune responses with variable clinical outcomes. We aimed to clarify the impact of attenuated heat-killed tuberculosis (HKTB) on tumor-associated macrophages which play critical roles in shaping immunological regulation in the tumor microenvironment. Upon HKTB stimulation, both primary macrophages derived from the peripheral blood of healthy subjects and from lung cancer patients as well as THP1-derived classically activated macrophages (Ms) and tumor-educated macrophages (TEMs) were polarized into the proinflammatory phenotype, as characterized by increased expression cluster of differentiation 86. A quantitative proteomic analysis revealed that stimulated TEMs were unable to activate the toll-like receptor 2, signal transducer and activator of transcription 1, or nuclear factor-κB signaling. Instead, they showed distinct intercellular adhesion molecule 1 signaling, impaired cell adhesion, and mitochondrial dysfunction. These molecular mechanisms might contribute to lower cytotoxicity of HKTB-stimulated TEMs against A549 cells via the release of distinct inflammatory cytokines compared to HKTB-stimulated Ms. Our study provides an unbiased and systematic interpretation of cellular and molecular alterations of HKTB-reeducated macrophages which should help illuminate potential strategies of HKTB-stimulated macrophage-based combination therapy for cancer treatment.

BACKGROUND: Biobanks play an essential role in the development of personalized medicine since they collect large numbers of high-quality biomaterials corresponding to clinical data. Despite its extensive population diversity, research institutions in Indonesia have indicated less awareness regarding biobanking for research practices.AIM: The journey to harmonize the knowledge and understanding of biobanks for health research and the development of the network in Indonesia has been summarized in this article.
METHODS: To build a national biobank network, in 2015 the Faculty of Medicine, Public Health and Nursing, UGM held the first national biobank network meeting in Indonesia. Follow-up meetings were then held to identify challenges and constraints faced by the network. Five annual national workshops (2015–2019) have been held.
RESULTS: Four working groups (WG) were formed to effectively coordinate the network, addressing the infrastructure and Laboratory Information Management System (WG 1), SOP and Best Practices (WG 2), Training and Education and Legal (WG 3), and Ethical and Social Issues (WG 4).
CONCLUSION: The formation of a national biobank network in Indonesia is based on the hope for multi-institutional collaboration to mainly foster the development of biobanks for health research with best available practices and provide a central hub of coordination.

Ika Fidianingsih, Teguh Aryandono, Sitarina Widyarini, Sri Herwiyanti, Sunarti Sunarti
Background: Breast cancer prevention still needs to be improved. Calorie restriction is thought to prevent breast cancer through the induction of autophagy. Maranta arundinacea L. (MA) has the potential for calorie restriction because it contains high fiber. This research aimed to observe the effect of dietary MA against dimethylbenz(a)anthracene (DMBA)-induced mammary cancer in Sprague Dawley rats related to autophagy. Methods: Twenty-five Sprague Dawley rats were randomly divided into five groups: 1) control group without DMBA-induced with a standard diet, 2) 20 mg/kg BW of DMBA two times a week for five weeks with a standard diet, 3) DMBA and diet modification with 30% of MA, 4) DMBA and diet modification with 45% of MA, and 5) DMBA and diet modification with 60% of MA. Examination of the nodule was conducted once every week for 22 weeks. Breast tissue/tumor examination underwent histology examination with hematoxylin-eosin. Examinations of immunohistochemical staining against Beclin1, LC3B, and SQSTM1 were conducted to reveal autophagy. The difference of autophagy protein expression was analyzed using One way ANOVA with 95% confidence level and significance set as p<0.05. Results: Cancer was detected in four rats of DMBA standard diet, two rats of 30% MA, one rat of 45% MA. No cancer was detected in the rats of control and rats with 60% of MA group. The Beclin1 expressions showed that the 60% of MA group had the
highest score (2.5±0.52) followed by the 45% of MA group (1.87±0.49), control group (1.77±0.11), 30% of MA group (1.28±0.75), and DMBA with standard diet had the lowest score (1.28±0.91). The difference of Beclin1 expressions was statistically significant (p-value=0.03). However, the difference of the LC3B expressions (p-value=0.11) and SQSTM1 expressions (p-value=0.225) were not statistically significant. Conclusion: Dietary modifications with MA potentially prevent breast cancer and induce initiation of autophagy.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a new virus responsible for the COVID-19 pandemic. The emergence of the new SARS-CoV-2 has been attributed to the possibility of evolutionary dynamics in the furin cleavage site (FCS) region. This study aimed to analyze the sequence of the FCS region in the spike protein of SARS-CoV-2 isolates that circulated in the Special Region of Yogyakarta and Central Java provinces in Indonesia. The RNA solution extracted from nasopharyngeal swab samples of confirmed COVID-19 patients were used and subjected to cDNA synthesis, PCR amplification, sequencing, and analysis of the FCS region. The sequence data from GISAID were also retrieved for further genome analysis. This study included 52 FCS region sequences. Several mutations were identified in the FCS region, i.e., D614G, Q675H, Q677H, S680P, and silent mutation in 235.57 C > T. The most important mutation in the FCS region is D614G. This finding indicated the G614 variant was circulating from May 2020 in those two provinces. Eventually, the G614 variant totally replaced the D614 variant from September 2020. All Indonesian SARS-CoV-2 isolates during this study and those deposited in GISAID showed the formation of five clade clusters from the FCS region, in which the D614 variant is in one specific cluster, and the G614 variant is dispersed into four clusters. The data indicated there is evolutionary advantage of the D614G mutation in the FCS region of the spike protein of SARS-CoV-2 circulating in the Special Region of Yogyakarta and Central Java provinces in Indonesia.
The role of gut microbiome in inflammatory skin disorders: A systematic review
Suci Widhiati, Dewajani Purnomosari, Tri Wibawa, Hardyanto Soebono
The close relationship between the intestine and the skin has been widely stated, seen from gastrointestinal (GI) disorders often accompanied by skin manifestations. Exactly how the gut microbiome is related to skin inflammation and influences the pathophysiology mechanism of skin disorders are still unclear. Many studies have shown a two-way relationship between gut and skin associated with GI health and skin homeostasis and allostasis. This systematic review aimed to explore the associations between the gut microbiome with inflammatory skin disorders, such as acne, psoriasis, atopic dermatitis, and urticaria, and to discover the advanced concept of this relationship. The literature search was limited to any articles published up to December 2020 using PubMed and EBSCOHost. The review followed the PRISMA guidelines for conducting a systematic review. Of the 319 articles screened based on title and abstract, 111 articles underwent full-text screening. Of these, 23 articles met our inclusion criteria, comprising 13 atopic dermatitis (AD), three psoriasis, four acne vulgaris, and four chronic urticaria articles. Acne vulgaris, atopic dermatitis, psoriasis, and chronic urticaria are inflammation skin disorders that were studied recently to ascertain the relationship of these disorders with dysbiosis of the GI microbiome. All acne vulgaris, psoriasis, and chronic urticaria studies stated the association of gut microbiome with skin manifestations. However, the results in atopic dermatitis are still conflicting. Most of the articles agree that Bifidobacterium plays an essential role as anti-inflammation bacteria, and Proteobacteria and Enterobacteria impact inflammation in inflammatory skin disorders.
Development of a Critical Appraisal Tool (AIMRDA) for the Peer-Review of Studies Assessing the Anticancer Activity of Natural Products: A Step towards Reproducibility
Rizwan Ahmad, Muhammad Riaz, Mohammed Aldholmi, Muhammad Asif Qureshi, Shahab Uddin, Ajaz Ahmad Bhat, Pratheeshkumar Poyil, Mukhtiar Baig, Jalal Pourahmad, Trivadi Ganesan, Abdul Quaiyoom Khan, Zainab Siddiqui, Maha El-Demellawy, Maryam Gholamalizadeh, Dewajani Purnomosari, Elsayed I Salim, Seyedeh Zahra Mousavi Jarrahi, Jian-ye Zhang, Samad Mohammadnejad, Alireza Mosavi Jarrahi
The journal of APJCP (Asian Pacific Journal of Cancer Prevention) focuses to gather relevant and up-to-date novel information’s related to cancer sciences. The research methodologies and approaches adopted by the researcher are prone to variation which may be desirable in the context of novel scientific findings however, the reproducibility for these studies needs to be unified and assured. The reproducibility issues are highly concerned when preclinical studies are reported in cancer, for natural products in particular. The natural products and medicinal plants are prone to a wide variation in terms of phytochemistry and phyto-pharmacology, ultimately affecting the end results for cancer studies. Hence the need for specific guidelines to adopt a best-practice in cancer research are utmost essential. The current AIMRDA guidelines aims to develop a consensus-based tool in order to enhance the quality and assure the reproducibility of studies reporting natural products in cancer prevention. A core working committee of the experts developed an initial draft for the guidelines where more focus was kept for the inclusion of specific items not covered
in previous published tools. The initial draft was peer-reviewed, experts-views provided, and improved by a scientific committee comprising of field research experts, editorial experts of different journals, and academics working in different organization worldwide. The feedback from continuous online meetings, mail communications, and webinars resulted a final draft in the shape of a checklist tool, covering the best practices related to the field of natural products research in cancer prevention and treatment. It is mandatory for the authors to read and follow the AIMRDA tool, and be aware of the good-practices to be followed in cancer research prior to any submission to APJCP. Though the tool is developed based on experts in the field, it needs to be further updated and validated in practice via implementation in the field.

Growth of exclusively breastfed small for gestational age term infants in the first six months of life: a prospective cohort study
Neti Nurani, Tunjung Wibowo, Rina Susilowati, Janatin Hastuti, Madarina Julia, Mirjam M. Van Weissenbruch
Background: Compared to their appropriate-for-gestational-age (AGA) peers, small-for-gestational-age (SGA) infants are prone to growth deficits. As the first 6 months of exclusive breastfeeding is generally recommended, it is essential to understand how this intervention might impact SGA infants’ growth. This study aims to assess growth of exclusively breastfed SGA term infants in the first 6 months of life. Methods: A prospective cohort study was conducted on term infants born in Dr. Sardjito General Hospital and two private hospitals in Yogyakarta, Indonesia. SGA was defined as birth weight less than the 10th percentile according to Fenton criteria. Weight, length, and head circumference (HC) were measured at birth and monthly until 6 months old. Results: A total of 39 AGA and 17 SGA term infants who were exclusively breastfed in their first 6 months were included and followed. In SGA compared to AGA, birth weight, length, and HC (mean ± SD) were significantly lower (p < 0.001). During the first 6 months, the SGAs grew in weight and length in parallel with the AGAs. At sixth months of age, the weight and length (mean ± SD) of the SGAs were significantly lower compared to the AGAs (p < 0.001). However, HC (mean ± SD) of SGAs grew significantly faster than the AGAs (p < 0.005). At sixth months of age, there were no significant differences in HC between the two groups (p = 0.824). Conclusions: In the first 6 months, exclusively breastfed SGA term infants, in contrast to weight and length, only show catch up growth in HC, leading to HC comparable to their AGA peers at the age of 6 months.

Toxic Substance-induced Hippocampal Neurodegeneration in Rodents as Model of Alzheimer’s Dementia
Open Access Macedonian Journal of Medical Sciences. 2021 Nov 08; 9(F):523-533.
BACKGROUND: Alzheimer’s Dementia (AD) cases are increasing with the global elderly population. To study the part of the brain affected by AD, animal models for hippocampal degeneration are still necessary to better understand AD pathogenesis and develop treatment and prevention measures. AIM: This study was a systematic review of toxic substance-induced animal models of AD using the Morris Water Maze method in determining hippocampal-related memory impairment. Our aim was reviewing the methods of AD induction using toxic substances in laboratory rodents and evaluating the report of the AD biomarkers reported in the models. METHODS: Data were obtained from articles in the PubMed database, then compiled, categorized, and analyzed. Eighty studies published in the past 5 years were included for analysis. RESULTS AND DISCUSSION: The most widely used method was intracerebroventricular injection of amyloid-β substances. However, some less technically challenging techniques using oral or intraperitoneal administration of other toxic substances also produce successful models. Instead of hippocampal neurodegeneration, many studies detected biomarkers of the AD pathological process while some reported inflammation, oxidative stress, neurotrophic factors, and changes of cholinergic activity. Female animals were underrepresented despite a high incidence of AD in women. CONCLUSION: Toxic substances may be used to develop AD animal models characterized with appropriate AD pathological markers. Characterization of methods with the most easy-handling techniques and more studies in female animal models should be encouraged.
Maxillofacial Trauma Severity Effects in Patients with Head Injury in a Tertiary Care Center in Yogyakarta, Indonesia
European Journal of Plastic Surgery
Background: Traumatic brain injury (TBI) is one of the leading causes of death and disability worldwide. In various combinations, a high frequency of facial bone fractures has been reported. However, the results are still conflicting. Methods: We retrospectively reviewed medical records of patients with maxillofacial trauma who were admitted to Dr. Sardjito Hospital, Yogyakarta, Indonesia, between January 2016 and December 2017. Results: A total of 70 patients with maxillofacial trauma were involved (57 males and 13 females, 18–65 years). Moreover, most of them were 18–25-year-old males (34.3%). The average patient age was 35.5 ± 14 years. No significant association was found between the sex and age group of the patient (p = 0.774). Motorcycle accident was the most frequent cause of maxillofacial fractures (84%) with midfacial and multiple maxillofacial fractures being the most frequent types found in patients (40% and 40%, respectively). The most common facial fracture was in the zygomatic bone (28%) and most cases showed mild facial injury (81%). A significant association was found between the Glasgow Coma Scale (GCS) and types of traumatic brain injury (TBI) (p = 0.031). However, when GCS was compared with facial injury, no statistically significant level was reached and its correlation was low (p = 0.267, r = 0.134). Conclusions: There was a significant association between types of traumatic brain injury with head injury severity. However, we found no correlation between head injury severity and facial injury severity. To explain and validate our results, further multicenter studies with a larger sample size are required. Level of evidence: Level IV, Risk/Prognostic.
Sex Differences in the Association of Vitamin D and Metabolic Risk Factors with Carotid Intimamedia Thickness in Obese Adolescents
PLoS One. 2021 Oct 15;16(10):e0258617.
doi: 10.1371/journal.pone.0258617. PMID: 34653200; PMCID: PMC8519449.
Background: It has been shown that vitamin D is associated with obesity and the development of atherosclerosis. Less is known about this association among adolescents with obesity. Objectives To determine the association of vitamin D level and metabolic risk factors with carotid intima-media thickness (CIMT) among obese adolescents. Methods: We conducted a cross-sectional study among obese children aged 15 to 17 years in Yogyakarta, Indonesia. The association of vitamin D and other metabolic risk factors (triglyceride, low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C), and insulin resistance using homeostasis model assessment of insulin resistance (HOMA-IR)) with CIMT was explored by multivariable linear regression models. Results: Out of 156 obese adolescents, 55.8% were boys. Compared to girls, boys had higher BMI z-score, waist circumference, and HDL-cholesterol. After adjustment for age, sex and second-hand smoke exposure, high HOMA-IR, total cholesterol, LDL-cholesterol and triglyceride levels were associated with higher odds of elevated CIMT. In analyses stratified by sex, a similar trend was observed in boys, while none of the risk factors were associated with CIMT in girls. We observed no association between vitamin D and CIMT. Conclusions: Hyperinsulinemia, higher total cholesterol and LDL cholesterol were associated with greater odds of elevated CIMT among obese adolescent boys.
Serum Endothelin-1 Level Positively Correlates with Waist and Hip Circumferences in Stable Coronary Artery Disease Patients
Reviews in Cardiovascular Medicine 2021, Vol. 22 Issue (3): 919-924
Central obesity is associated with increased level and activity of endothelin-1. The waist and hip circumferences are simple indicators of central obesity. Waist circumference correlates with visceral adiposity, whereas hip circumference associates with gluteofemoral peripheral adiposity. Both measurements have independent and opposite correlation with coronary artery disease (CAD) risk factors. The relation between serum endothelin-1 in stable CAD and both parameters of central obesityneeds to be investigated. This study aims to examine the correlation between serum endothelin-1 level and waist and hip circumferences as parameters of central obesity in patients with stable CAD. This was a cross-sectional study. Consecutive subjects were enrolled among those who underwent elective coronary angiography with significant CAD. Serum endothelin-1 was measured from peripheral blood samples taken before coronary angiography procedure. The measurement of waist circumference, hip circumference, and ratio derived from them, was performed. Central obesity was determined by waist circumference cut-off for Indonesian population. The correlation analysis was performed with Pearson test. The multivariate analysis was performed with multiple linear regression test. The comparison of serum endothelin-1 level between groups was performed with Student T test. We enrolled 50 subjects. The majority of subjects was male (80.0%), hypertensive (86.0%), dyslipidemic (68%) and smoker (52%). Most subjects had history of acute coronary syndrome (64%). Mean waist circumference was 87.6 +/- SD cm, hip circumference was 95.3 cm +/- SD, mean waist-to-hip ratio was 0.92 +/- SD and mean waist-to-height ratio was 0.54 +/- SD. Central obesity occurred in 32% of subjects. Mean serum endothelin-1 level was 2.2 ± 0.7 pg/mL. Serum endothelin-1 level tended to be higher in subjects with central obesity as compared to those without. Serum endothelin-1 level was significantly correlated with age, hemoglobin level, waist circumference (coefficient of 0.311, p value = 0.023) and hip circumference (coefficient of 0.359, p value = 0.010). Multivariable analysis indicated that age (coefficient of -0.353, p value = 0.007) and hip circumference (coefficient of 0.335, p value = 0.011) were independently correlated with serum endothelin-1. For conclusion, in patients with stable CAD, serum endothelin-1 was positively correlated with both waist circumference and hip circumference. Hip circumference independently and positively correlated with serum endothelin-1 level.
CREB Signaling Activity Correlates with Differentiation and Survival in Medulloblastoma
Sci Rep. 2021 Aug 9;11(1):16077.
DOI: 10.1038/s41598-021-95381-0. PMID: 34373489; PMCID: PMC8352923
While there has been significant progress in the molecular characterization of the childhood brain cancer medulloblastoma, the tumor proteome remains less explored. However, it is important to obtain a complete understanding of medulloblastoma protein biology, since interactions between proteins represent potential new drug targets. Using previously generated phosphoprotein signaling-profiles of a large cohort of primary medulloblastoma, we discovered that phosphorylation of transcription factor CREB strongly correlates with medulloblastoma survival and associates with a differentiation phenotype. We further found that during normal cerebellar development, phosphorylated CREB was selectively expressed in differentiating cerebellar granule neuron progenitor (CGNP) cells. In line, we observed increased differentiation in CGNPs treated with Forskolin, Bmp6 and Bmp12 (Gdf7), which induce CREB phosphorylation. Lastly, we demonstrated that inducing CREB activation via PKA-mediated CREB signaling, but not Bmp/MEK/ERK mediated signalling, enhances medulloblastoma cell sensitivity to chemotherapy.

TNF-alfa and the Presence of Macrophage M2 and T Regulatory Cells in Nasopharyngeal Carcinoma
Asian Pac J Cancer Prev. 2021 Aug 1;22(8):2363-2370.
Objective: To investigate the correlation between TLR3 and pro-inflammatory cytokines (TNFα, IL6) expression with the distribution of macrophage M2 and Treg on Epstein Barr virus-encoded RNAs (EBER+) nasopharyngeal carcinoma (NPC) tissues. Methods: A total of 23 FFPE NPC tissue samples were obtained from patients in Dr. Sardjito General Hospital, Yogyakarta, Indonesia in 2008–2010, which expressed EBER was collected. The expressions of TLR3, TNFα, and IL6 were examined using an immunofluorescence assay. The distribution of macrophage M2 and Treg were examined by immunohistochemistry with anti-CD163 and -FOXP3 antibodies, respectively. The quantification of fluorescence intensity was analyzed by the RGB space method using ImageJ software. The M2 interpretation was done by the eyeballing method and the M2 scores were divided into 0 (negative), 1 (scant), 2 (focal), 3 (abundant). The average number of Treg FOXP3+ cells in five high power fields was counted. The relationship between variables was tested by the Spearman correlation test, and the coefficient correlation was used to see the correlation between variables. Results: All EBER+ NPC specimens showed TLR3 expression intracellularly. The expression of TNFα could be observed in the cell membranes and secreted extracellularly, while IL6 was secreted to the extracellular area. The expression of TNFα was two times higher than IL6. Most specimens showed low M2 score (56.52%) and high Treg (52.17%). A positive correlation was found between TLR3 and IL6 (12.9%). TNFα was positively correlated with the M2 distribution of 13.7% and Treg distribution of 12.9%, while the rest were explained by other factors. Conclusion: TNFα has a positive correlation with M2 and Treg distribution, but mostly through a different mechanism other than EBER-TLR3 interaction. Possibly, other pro-inflammatory and anti-inflammatory cytokines are involved in the formation of the NPC microenvironment, especially related to the presence of M2 and Treg, which provide immunosuppressive effects in NPC tumors
Development of Tetra-primer Amplification Refractory Mutation System (ARMS) PCR for Detection of CHRNA3 rs8040868
The Indonesian Biomedical Journal, Vol.13, No.2, June 2021, p.106-220
BACKGROUND: Single nucleotide variations (SNV) have been mapped to be associated with several human conditions and diseases. To validate the association between SNV to certain human traits or diseases, a large number of subjects must be included. Thus, in need of a fast, relatively economic, and reliable genotyping method. This can be achieved through the use of tetra-primer amplification refractory mutation system polymerase chain reaction (Tetra-primer ARMS PCR). This study reports strategy to develop Tetra-primer ARMS PCR-based genotyping of CHRNA3 rs8040868. METHODS: The optimization of Tetra-primer ARMS PCR was done through these steps: identification of gene sequence and position of single mutation; designing outer and inner PCR primers; amplification of target gene fragments through PCR by using outer primer; confirming genotype of the PCR product by using sequencing; determining an optimum ratio of outer and inner primer; and determining optimum annealing temperature and cycles for the PCR program. The PCR products were run in 2% gel agarose electrophoresis and visualized under UV illumination. RESULTS: Outer and inner primer ratio of 1:3 with annealing temperature of 64.4oC and 40x cycles was found to be the most optimum condition. Tetra-primer ARMS PCR was able to confirm the results of the DNA sequence of 2 samples, confirming wild-type variants (TT allele) and the heterozygous mutant (CT allele). CONCLUSION: Tetra-primer ARMS PCR was able to genotype rs8040868 of the CHRNA3 gene.
Novel Mutations of Epidermolysis Bullosa Identified Using Whole-exome Sequencing in Indonesian Javanese Patients
Intractable & Rare Diseases Research. 2021; 10(2):88-94.
Epidermolysis bullosa (EB) is a group of inherited blistering skin diseases known to have heterogenicity of phenotypes and genotypes. There are four main types of EB: Simplex, junctional, dystrophic, and Kindler syndrome, which are further classified into 34 distinct subtypes. Twenty different gene mutations are responsible for the loss of function and integrity of the basal membrane zone. In limited-resource settings such as Indonesia, diagnoses of hereditary skin disease often rely on clinical features. This limitation was managed by using the Clinical Diagnostic Matrix EB for clinical diagnosis support and whole-exome sequencing for genetic analysis. This study is the first whole-exome sequencing analysis of Javanese Indonesian patients with EB. The genetic analysis from four patients with EB identified all novel mutations unreported in the dbSNP database. There is Kindler syndrome with FERMT1 frameshift mutation in exon 4, at c.388A (p.I130fs), which causes truncated protein; junctional EB generalized intermediate (JEB-GI) subtype with missense mutation at LAMB3 gene position c.A962C (p.H321P); and recessive dystrophic EB (RDEB) a missense mutation at COL7A1 gene position c.G5000T (p.G1667V). The whole-exome sequencing was further verified by Sanger sequencing. The new mutations’ finding is possibly due to the limited genetic database in the Malayo-Polynesian ethnic group. Indonesia has hundreds of ethnic groups, and the Javanese is the largest ethnic group that populates Indonesia. Genetic data of these ethnic groups is important to be established in the international genetic database. This combination of clinical diagnostic and genetic analysis tools with whole-exome sequencing confirmed the challenging diagnosis of epidermolysis bullosa.

Front Pediatr. 2021 May 25;9:680869.
doi: 10.3389/fped.2021.680869. PMID: 34113592; PMCID: PMC8185158.
Background: Interactions between the genome and intrauterine environment can affect bone mineralization in newborns and even in adult life. Several studies show that intrauterine fetal bone mineralization or early postnatal bone condition influences the risk of osteoporosis in later life. Objectives: To determine whole body bone mineral content (WB BMC) and factors that influence neonatal WB BMC in Indonesian term newborns. Subjects/Methods: A cross-sectional study was conducted in Dr. Sardjito General Hospital, Yogyakarta, Indonesia. A total of 45 term, appropriate for gestational age (AGA) newborns were included in this study. BMC was assessed by dual-energy x-ray absorptiometry (DXA) in the first week of life. Weight (g), length (cm) and head circumference (cm) were measured at birth. Data on maternal characteristics were obtained from the maternal health records or reported by the mothers. Results: WB BMC measured in the present study (mean ± SD: 33.2 ± 9.3 g) was lower than WB BMC of similar populations in developed countries. Multiple linear regression showed that birth weight, birth length, and gestational age had a positive association with WB BMC (p = 0.048, 0.017, and <0.001, respectively), while maternal cigarette exposure had a negative association with WB BMC (p = 0.012). Male infants had significantly higher of WB BMC than female (p = 0.025). These determinants contribute to 55% variability of WB BMC. Conclusions: WB BMC in Indonesian term newborns is lower than populations in developed countries. Birth weight, length, gestational age, sex, and maternal cigarette exposure during pregnancy are significantly associated with WB BMC observed in Indonesian newborns.
The Distribution of M2 Macrophage and Treg in Nasopharyngeal Carcinoma Tumor Tissue and the Correlation with TNM Status and Clinical Stage
Asian Pacific Journal of Cancer Prevention. Volume 22, Issue 11, Pages 3447 – 3453
Objective: This study aimed to identify the distribution of M2 macrophage and Treg in Nasopharyngeal Carcinoma (NPC) tumor tissue samples. The presence of these two groups of cells was further correlated to clinical stage, tumor size, the lymphatic node involvement, and metastasis. Methods: The total of 50 formalin-fixed paraffin-embedded (FFPE) NPC tissue samples was collected retrospectively (27 samples) and prospectively (23 samples). Samples were FFPE tissue slices. Immunohistochemistry was done on the FFPE tissue slides using anti-CD-163 and anti-FoxP-3 antibodies for M2 macrophage and Treg detection, respectively. The M2 macrophage interpretation was performed by eye-balling method and the score was divided into 0 (negative), 1 (scant), 2 (focal), and 3 (abundant). The average number of Treg FOXP3+ cells in 5 high power fields (HPF) was calculated. The relationship of M2 macrophage and Treg was tested with Spearman’s correlation. The relationship between M2 macrophage and Treg with clinical stage, tumor size, node involvement and metastasis was tested by chi square, with p<0.1. Results: M2 macrophage and Treg were positive correlated (r=0.469, p<0.001). The presence of M2 macrophage and regulatory T cell (Treg) was significantly correlated to tumor size (p= 0.091 for M2 macrophage and p=0.022 for Treg) and clinical stage (p= 0.030 for M2 macrophage and p= 0.002 for Treg), but did not correlate with lymphatic node involvement and metastasis. Conclusions: In Epstein-Barr virus related NPC tumor microenvironment, the presence of M2 macrophage was correlated with Treg, and both types of the cells were correlated with tumor size and clinical stages.
Neurological Involvement of COVID-19: from Neuroinvasion and Neuroimmune Crosstalk to Long-term Consequences
Septyaningtrias DE, Susilowati R. Neurological Involvement of COVID-19: from Neuroinvasion and Neuroimmune Crosstalk to Long-term Consequences. Rev Neurosci. 2021 Feb 1;32(4):427-442. doi: 10.1515/revneuro-2020-0092.
As the coronavirus disease 2019 (COVID-19) pandemic continues to be a multidimensional threat to humanity, more evidence of neurological involvement associated with it has emerged. Neuroimmune interaction may prove to be important not only in the pathogenesis of neurological manifestations but also to prevent systemic hyperinflammation. In this review, we summarize reports of COVID-19 cases with neurological involvement, followed by discussion of possible routes of entry, immune responses against coronavirus infection in the central nervous system and mechanisms of nerve degeneration due to viral infection and immune responses. Possible mechanisms for neuroprotection and virus-associated neurological consequences are also discussed.
