Coping Mechanisms Utilized by Drug Addicts in Overcoming Challenges During the Recovery Process: A Qualitative Meta-Synthesis.

Objectives: Recovery from drug addiction frequently presents difficulties for addicts. The coping mechanisms drug addicts employ to resist temptations and deal with stress are an important part of this healing process. The purpose of this study is to investigate the coping mechanisms or ways drug addicts employ to manage stress and temptations while undergoing treatment. Methods: A qualitative meta-synthesis method is used in this work to critically assess pertinent qualitative studies. Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020 is the guideline for article search, and it applies to four academic databases: Scopus, PubMed, ProQuest, and CINAHL. Based on predetermined inclusion criteria, the assessed studies comprise research published between 2014 and 2023. The CASP (Critical Appraisal Skills Programme) Qualitative Studies Checklist is used to gauge the quality of studies. This study was registered in PROSPERO (International Prospective Register of Systematic Reviews) with the registration number CRD42024497789. Results: Five major themes are found from thirteen qualifying qualitative articles to illustrate the different coping mechanisms used by drug users in their quest for recovery. Seeking Social Support is one of these five topics, along with Psychological Coping Strategies, Spiritual Experiences, Professional Interventions, and Awareness Enhancement. Conclusion: Drug addicts' coping mechanisms play a critical role in assisting them in resisting stress and temptations during their recovery. Healthcare professionals are among the medical specialists who can create more comprehensive and successful plans to help drug users on their road to recovery.

TBX3 transfection and nodal signal pathway inhibition promote differentiation of adipose mesenchymal stem cell to cardiac pacemaker-like cells.

BACKGROUND: Mesenchymal stem cells (MSCs) are known as one of the best candidate cells to produce cardiac pacemaker-like cells (CPLCs). Upregulation of TBX3 transcription factor and inhibition of the nodal signal pathway have a significant role in the formation of cardiac pacemaker cells such as sinoatrial and atrioventricular nodes, which initiate the heartbeat and control the rhythm of heart contractions. This study aimed to confirm the effects of transfection of TBX3 transcription factor and inhibition of the nodal signal pathway on differentiating adipose-derived MSCs (AD-MSCs) to CPLCs. AD-MSCs were characterized using flow cytometry and three-lineage differentiation staining. METHODS: The transfection of TBX3 plasmid was carried out using lipofectamine, and inhibition of the nodal signal pathway was done using the small-molecule SB431542. The morphology of the cells was observed using a light microscope. Pacemaker-specific markers, including TBX3, Cx30, HCN4, HCN1, HCN3, and KCNN4, were evaluated using the qRT-PCR method. For protein level, TBX3 and Cx30 were evaluated using ELISA and immunofluorescence staining. The electrophysiology of cells was evaluated using a patch clamp. RESULTS: The TBX3 expression in the TBX3, SM, and TBX + SM groups significantly higher (p < 0.05) compared to the control group and cardiomyocytes. The expression of Cx40 and Cx43 genes were lower in TBX3, SM, TBX + SM groups. In contrast, Cx30 gene showed higher expression in TBX3 group. The expression HCN1, HCN3, and HCN4 genes are higher in TBX3 group. CONCLUSION: The transfection of TBX3 and inhibition of the nodal signal pathway by small-molecule SB431542 enhanced differentiation of AD-MSCs to CPLCs.

First French and Indonesian university medical cooperation for promoting emergency medicine.

Indonesia and French Guiana share many geographic and medical concerns regarding access to care. The organisational needs in emergency management, particularly in the prehospital phase, are similar. Whereas emergency medicine (EM) is an academic and entire speciality in France, it is still under construction in Indonesia. In the framework of the French and Indonesian academic cooperation, the Medical school in Jakarta University and the French Guiana University in Cayenne signed a Memorandum of Understanding encompassing education programmes, joint research work and students' and health professionals' exchanges in EM. This partnership represented the first medical cooperation programme between the two countries. The first student class was launched in August 2022 and involved 50 Indonesian doctors who graduated in August 2023. The implementation and success of this Franco-Indonesian cooperation were supported by political and academic partners from the two sides. Given the first student class's success, we aim to continue this programme, in line with Indonesia and World Health Organization's plan to establish a multi-country training hub for health emergency operational readiness and Emergency Medical Teams.

The Effectiveness of Indonesia's Seven - Step Return to Work Assessment on a Distal Tarsal Tunnel Syndrome : A Case Report Study.

Tarsal tunnel syndrome (TTS) is a nerve entrapment of the posterior tibial nerve. This uncommon condition frequently goes undiagnosed or misdiagnosed even though it interferes with the daily activities of workers. Here we discuss the return to work status of a 37-year-old male patient who manages a manufacturing plant. He was identified as having Tarsal Tunnel Syndrome as a result of a foot abnormality and improper shoe wear. He had moderate pes planus and underwent tarsal tunnel release on his right foot. What are the determinant factors in defining a patient's status for returning to work after a tarsal tunnel release? We conducted a literature review using PubMed, Science Direct, and Cochrane. The Indonesian Occupational Medicine Association used the seven-step return-to-work assessment as a protocol to avoid overlooking the process. Duration of symptoms, associated pathology, and the presence of structural foot problems or a space-occupying lesion are factors affecting outcome. Post-operative foot scores, including Maryland Foot Score (MFS), VAS, and Foot Function Index, can be used to evaluate patient outcomes. Early disability limitation and a thorough return-to-work assessment are needed.

Health Transformation in Indonesia Through Health Digitalization Strengthening: A Perspective From Occupational Health.

Digital health implementation is crucial to make the greatest benefit to a country's citizens, including its workers. This article describes the implementation of digital health in both general health and occupational health. An internet search regarding the implementation of digital health, telemedicine, and telehealth in Indonesia was performed during July - August 2023. Publications released from the Ministry of Health Republic of Indonesia, the Ministry of Labour, Manpower and Transmigration of the Republic of Indonesia, as well as from various sources regarding digital health and telemedicine, were used in the writing of this article. Digital health transformation in Indonesia has been set as national goal since 2021 and some challenges still present as potential setbacks of nationwide digital health implementation.

Stigma, depression, quality of life, and the need for psychosocial support among people with tuberculosis in Indonesia: A multi-site cross-sectional study.

Stigma towards people with tuberculosis (TB-Stigma) is associated with other psychosocial consequences of TB including mental illness and reduced quality of life (QoL). We evaluated TB-Stigma, depression, QoL, and the need for psychosocial support among adults with TB in Indonesia, a high TB burden country. In this primary health facility-based survey in seven provinces of Indonesia, from February to November 2022, we interviewed adults receiving (a) intensive phase treatment for drug-susceptible (DS) TB at public facilities, (b) treatment at private facilities, (c) those lost to follow up (LTFU) to treatment, and (d) those receiving TB retreatment. We used our previously validated Indonesian TB-Stigma Scale, Patient Health Questionnaire-9, and EQ-5D-5L to measure TB-Stigma, depression, and QoL. Additional questions assessed what psychosocial support was received or needed by participants. We recruited and interviewed 612 people, of whom 60.6% (96%CI 59.6-64.5%) experienced moderate TB-Stigma. The average TB-Stigma scores were 19.0 (SD 6.9; min-max 0-50; Form A-Patient Perspective) and 23.4 (SD 8.4, min-max 0-50; Form B-Community Perspective). The scores were higher among people receiving treatment at private facilities (adjusted B [aB] 2.48; 0.94-4.03), those LTFU (aB 2.86; 0.85-4.87), males (aB 1.73; 0.59-2.87), those losing or changing job due to TB (aB 2.09; 0.31-3.88) and those living in a rural area (aB 1.41; 0.19-2.63). Depression was identified in 41.5% (95% CI 37.7-45.3%) of participants. Experiencing TB-Stigma was associated with moderately severe to severe depression (adjusted odds ratio [aOR] 1.23; 1.15-1.32) and both stigma and depression were associated with lower QoL (aB -0.013; [-0.016]-[-0.010]). Informational (20.8%), emotional (25.9%) and instrumental (10.6%) support received from peers or peer-groups was limited, and unmet need for such support was high. There is a sizeable and intersecting burden of TB-Stigma and depression among adults with TB in Indonesia, which is associated with lower QoL. Participants reported a substantial unmet need for psychosocial support including peer-led mutual support groups. A community-based peer-led psychosocial support intervention is critical to defray the psychosocial impact of TB in Indonesia.

Asian Intensive Reader of Pneumoconiosis program: examination for certification during 2008-2020.

This study examined physicians' participation and performance in the examinations administered by the Asian Intensive Reader of Pneumoconiosis (AIR Pneumo) program from 2008 to 2020 and compared radiograph readings of physicians who passed with those who failed the examinations. Demography of the participants, participation trends, pass/fail rates, and proficiency scores were summarized; differences in reading the radiographs for pneumoconiosis of physicians who passed the examinations and those who failed were evaluated. By December 2020, 555 physicians from 20 countries had taken certification examinations; the number of participants increased in recent years. Reported background specialty training and work experience varied widely. Passing rate and mean proficiency score for participants who passed were 83.4% and 77.6 ± 9.4 in certification, and 76.8% and 88.1 ± 4.5 in recertification examinations. Compared with physicians who passed the examinations, physicians who failed tended to classify test radiographs as positive for pneumoconiosis and read a higher profusion; they likely missed large opacities and pleural plaques and had a lower accuracy in recognizing the shape of small opacities. Findings suggest that physicians who failed the examination tend to over-diagnose radiographs as positive for pneumoconiosis with higher profusion and have difficulty in correctly identifying small opacity shape.

The effects of prolonged stress exposure on the brain of rats and insights to understand the impact of work-related stress on caregivers.

Introduction: Stress exposure is a significant concern in the healthcare sector. This animal model study aims to reproduce caregivers' working conditions and determine their impact on the brain. Method: Twenty-four healthy male rats of the Wistar strain were divided into four groups. Three groups were submitted each to one stressor for 21 days, while the fourth group was used as a control. Stressors were food and water deprivation (FW), permanent illumination (PI), and forced swimming (FS). At the end of the experiment, rats were euthanized, and stress biomarkers, biological parameters, and DNA damage were measured. Results: Prooxidant biomarker rates increased in the different groups (+50 to +75%) compared to the control (p < 0.0001). Urinary corticosterone rates increased in all stressed animals, mainly in the PI group, with changes of up to +50% compared to the control group. Acetylcholinesterase levels decreased to -50% (p < 0.0001 for the three exposed groups). Total ATPase, (Na+/K+)-ATPase, and Mg2+-ATPase activities decreased in all stressed groups. The percentage of brain cell congestion and apoptosis was 3% for the FW group (p < 0.0001), 2% for the PI group (p < 0.0001), and 4% for the FS group (p < 0.0001) compared to the control (0.8%). DNA damage was observed in all exposed groups. Finally, we noticed behavioral changes and a depression-like syndrome in all stressed rats. Conclusion: Stressful conditions such as the working environment of caregivers can trigger several pathophysiological processes leading to oxidative, neurochemical, and hypothalamic-pituitary-adrenal disorders. These changes can progress to cell damage and apoptosis in the brain and trigger psychological and physical disorders.

CXCL8, MMP1, MMP2, and FN1 Gene Expression and Tumor Extension in Nasopharyngeal Cancer Patients: A Cross-sectional Study.

BACKGROUND: There are correlations between tumor staging, lymph node involvement, and patient survival in Nasopharyngeal cancer (NPC) which is one of the most common types of cancer in Indonesia.  The inflammation process plays a role in tumor progression over the long term and this marked by increased proinflammatory cytokine and gene overexpression. This study aims to identify differentially expressed genes (DEGs) in NPC using T and N staging. METHODS: This is a cross-sectional study of NPC patients in Cipto Mangunkusumo, Jakarta, between 2018 and 2022. DEGs were identified based on the amount of mRNA detected on paraffin blocks with a 1.5- to -1.5-fold change and an adjusted p-value of <0.05. RESULTS: We included 48 subjects. The mean age of subjects was 47.75 (10.48) years, and most were male (77.1%). Non-keratinized squamous cell carcinoma was the most common histopathology type. Differences in the tumor size of the T4 and non-T4 in metastatic (33.3%) group when compared to the non-metastatic (37.5%) group were insignificant (p = 0.763). The proportion of N3 subjects in the metastatic vs non-metastatic group was different significantly (83.3% vs. 50%, p = 0.030). Gene expression analysis showed that C-X-C motif ligand 8 (CXCL8), matrix metalloproteinase-1 (MMP1), matrix metalloproteinase-1 (MMP2), and fibronectin-1 (FN1) genes of the T4 and non-T4 group to be different significantly. CONCLUSION: There was significant finding in the N3 subjects of the metastatic and non-metastatic groups. The DEGs of CXCL8, MMP1, MMP2, and FN1 were statistically significant in the T4 when compared to the non-T4 group.

Designing Optimal Food-Based Recommendations and Nutrient-Dense Canteen Menu for Oil and Gas Workers Using Linear Programming: A Preliminary Study in Oil and Gas Worksite in East Kalimantan, Indonesia.

The objective of this study is to identify problem nutrients and to develop food-based recommendations (FBRs) and nutrient-dense menus based on the nutrient gaps. This study was conducted among male workers (n = 31) in an oil and gas worksite in East Kalimantan, Indonesia. Body weight, height, waist circumference, as well as systolic and diastolic blood pressure were measured. Weekly food consumption patterns were assessed using 1 day 24 h dietary recall (24HR), 1 day weighed food record (WFR), and 5 day food tally. Linear programming (LP) analysis using WHO Optifood software was used to identify problem nutrients and develop FBRs. The identified nutrient gaps were inserted in the nutrient-dense menu for the worksite canteen. Obesity, central obesity, and hypertension were reported in 64.5%, 48.4%, and 3.2% of the workers. Calcium, folate, total PUFA, n-6 PUFA, and dietary fiber were identified as problem nutrients. The FBRs can improve the intake of problem nutrients from 20% of recommended nutrient intake (RNI) in the nonoptimized diet to 50-70% RNI in the optimized diet, while controlling the intake of sodium and saturated fat within an acceptable range. The remaining nutrient gaps (calcium, total PUFA, n-6 PUFA, and dietary fiber) were inserted into the 14-day modified canteen snack menu. This study provides initial evidence that a combination of FBRs and a modified canteen menu can optimize the diet of the workers. Further studies assessing the effectiveness of the developed FBRs and modified menus are needed.

Intramyocardial Stem Cell Transplantation during Coronary Artery Bypass Surgery Safely Improves Cardiac Function: Meta-Analysis of 20 Randomized Clinical Trials.

IMSC transplantation during CABG is considered one of the most promising methods to effectively deliver stem cells and has been widely studied in many trials. But the results of outcomes and safety of this modality still vary widely. We conducted this meta-analysis of randomized controlled trials (RCTs) to evaluate not only the outcome but also the safety of this promising method. A meta-analysis was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. A comprehensive literature search was undertaken using the PubMed, Scopus, and Cochrane databases. Articles were thoroughly evaluated and analyzed. Twenty publications about IMSC during CABG were included. Primary outcomes were measured using LVEF, LVESV, LVESVI, LVESD, LVEDV, LVEDVI, LVEDD, WMSI, and 6-MWT. Safety measures were depicted by total deaths, MACE, CRD, CVA, myocardial infarction, ventricular arrhythmia, and cardiac-related readmission. IMSC transplantation during CABG significantly improved LVEF (MD = 3.89%; 95% CI = 1.31% to 6.46%; p = 0.003) and WMSI (MD = 0.28; 95% CI = 0.01-0.56; p = 0.04). Most of the other outcomes showed favorable results for the IMSC group but were not statistically significant. The safety analysis also showed no significant risk difference for IMSC transplantation compared to CABG alone. IMSC during CABG can safely improve cardiac function and tend to improve cardiac volumes and dimensions. The analysis and application of influencing factors that increase patients' responses to IMSC transplantation are important to achieve long-term improvement.

The determinants of thyroid function among vegetable farmers with primary exposure to chlorpyrifos: A cross-sectional study in Central Java, Indonesia.

Objectives: Occupational pesticide exposure, chlorpyrifos (CPF) in particular, may adversely affect the thyroid. The purpose of this study was to evaluate the determinants of thyroid function as indicated by the serum concentration of thyroid-stimulating hormone (TSH) among Indonesian vegetable farmers with primary exposure to CPF. Methods: A total of 151 vegetable farmers participated in this study. The sociodemographic and occupational characteristics of the participants were obtained using a structured interviewer-administered questionnaire. A validated quantitative method was used to estimate the cumulative exposure level (CEL). Serum TSH, thyroglobulin (Tg), free thyroxine (FT4), and urinary iodine excretion (UIE) were measured in the laboratory. The difference in TSH concentrations according to CEL and other characteristics were analysed using the Mann-Whitney U test. A multiple linear regression model was used to evaluate the potential determinants of TSH. Results: The mean age was 50 (SD 9.4) years. The median concentrations of TSH, FT4, and Tg/FT4 ratio were 1.46 mIU/L, 1.17 ng/dL, and 6.23 × 102, respectively. We observed that higher TSH concentrations were found among those with a higher Tg/FT4 ratio, were classified as high CEL, and had lower UIE or FT4. Conclusions: Our findings show that Tg/FT4 ratio, CEL, FT4, UIE concentrations, and post-spraying days were determinants of TSH concentrations among farmers with primary exposure to CPF. These results indicate that farmers are exposed to agents with thyroid-disrupting properties, thus supporting previous evidence showing the potential for thyroid disorders in agricultural populations exposed to pesticides.

Stigma towards people with tuberculosis: a cross-cultural adaptation and validation of a scale in Indonesia.

INTRODUCTION: Tuberculosis (TB) remains a highly stigmatised disease that can cause or exacerbate mental health disorders. Despite increased awareness of the importance of reducing TB stigma, validated tools to measure TB stigma remain scarce. This study aimed to culturally adapt and validate the Van Rie TB Stigma Scale in Indonesia, a country with the second largest TB incidence worldwide. METHODS: We validated the scale in three phases: translation, cultural adaptation, and psychometric evaluation. We invited diverse experts to an interdisciplinary panel for the cross-cultural adaptation, then performed a psychometric evaluation of the scale: exploratory and confirmatory factor analyses, reliability analysis, and correlation analysis with Patient Health Questionnaire 9 [PHQ-9]. RESULTS: We culturally adapted the original scale's language and content during the translation and cultural adaptation phases. After psychometric evaluation with 401 participants in seven provinces of Indonesia, we removed two items. The new scale had two forms: (A) patient and (B) community perspective forms. Both forms had good internal consistency, with respective Cronbach's alpha values of 0.738 and 0.807. We identified three loading factors in Form A (disclosure, isolation, and guilty) and two loading factors in Form B (isolation and distancing). The scale showed correlation with PHQ-9 (Form A, rs = 0.347, p < 0.001; Form B, rs = 0). CONCLUSIONS: The culturally adapted Indonesian version of Van Rie's TB Stigma Scale is comprehensive, reliable, internally consistent, and valid. The scale is now ready for applied scale-up in research and practice to measure TB-stigma and evaluate the impact of TB-stigma reduction interventions in Indonesia.

Correlation Between Cardiac Index, Plasma Troponin I, Myocardial Histopathology, CPB and AoX Duration in Glutamine versus No Glutamine Administered Patients with Low Ejection Fraction Undergoing Elective On-Pump CABG Surgery: Secondary Analysis of an RCT.

Purpose: On-pump coronary artery bypass graft (CABG) causes myocardial ischemia, through the cardiopulmonary bypass (CPB) and aortic cross-clamping (AoX). Glutamine supplementation protects cardiac cells during cardiac ischemia. This study analysed the correlation between cardiac index (CI), plasma troponin I, myocardial histopathology, CPB and AoX duration in low ejection fraction patients receiving glutamine and no glutamine undergoing elective on-pump CABG. Material and Methods: This was a secondary analysis of a double-blind, randomised controlled trial of 60 patients, split into control and intervention (glutamine) groups. Glutamine was administered at a dose of 0.5 g/kg/24 hours. There were 29 patients in each respective groups after a total of two patients dropped out. Results: A negative correlation (p = 0.037) was observed between CPB duration and CI at 6 hours after CPB in the glutamine group. A positive correlation (p = 0.002) was also observed between AoX duration and plasma troponin I at 6 hours after CPB in the control group. However, no correlation was observed between myocardial histopathology and plasma troponin I level at 5 minutes after CPB. Conclusion: Significant negative correlation between CPB duration and CI at 6 hours after CPB in the glutamine group, along with significant positive correlation between AoX duration and plasma troponin I level at 6 hours after CPB in the control group demonstrated the myocardial protection qualities of intravenous glutamine administration in patients with low ejection fraction undergoing elective on-pump CABG surgeries.

Developing a tool to measure tuberculosis-related stigma in workplaces in Indonesia: An internal validation study.

Workers with tuberculosis (TB) are often stigmatized, negatively impacting their socioeconomic position, mental health, and TB treatment outcomes. There is a dearth of validated tools to assess stigma in the worker population. This study aimed to develop and validate a novel, culturally adapted tool to measure TB-related stigma among workers in Indonesia. We translated, adapted, applied, and internally validated Van Rie's TB-Stigma Scale to the worker population in varying sizes businesses (formal and informal business sectors) in Indonesia. Psychometric evaluation using exploratory and confirmatory factor analyses (EFA and CFA) was performed to check the tool's internal consistency and reliability. The translation and cultural adaptation phases resulted in a final 11-item tool. From 172 participant responses, the EFA found two loading factors relating to responses on isolation and exclusion from the workplace. The CFA confirmed that the developed model had moderate fit with R2 values for each item ranging from 0.37 to 0.84. The tool was reliable (Cronbach's alpha 0.869). This validated, consistent and reliable adapted tool is ready to use in larger scale evaluations of TB-related stigma amongst workers in formal and informal business sectors of Indonesia to develop strategies to eliminate TB-related stigma from the workplace.

Interventions pathways to reduce tuberculosis-related stigma: a literature review and conceptual framework.

BACKGROUND: Prevention of tuberculosis (TB)-related stigma is vital to achieving the World Health Organisation's End TB Strategy target of eliminating TB. However, the process and impact evaluation of interventions to reduce TB-stigma are limited. This literature review aimed to examine the quality, design, implementation challenges, and successes of TB-stigma intervention studies and create a novel conceptual framework of pathways to TB-stigma reduction. METHOD: We searched relevant articles recorded in four scientific databases from 1999 to 2022, using pre-defined inclusion and exclusion criteria, supplemented by the snowball method and complementary grey literature searches. We assessed the quality of studies using the Crowe Critical Appraisal Tool, then reviewed study characteristics, data on stigma measurement tools used, and interventions implemented, and designed a conceptual framework to illustrate the pathways to TB-stigma reduction in the interventions identified. RESULTS: Of 14,259 articles identified, eleven met inclusion criteria, of which three were high quality. TB-stigma reduction interventions consisted mainly of education and psychosocial support targeted predominantly toward three key populations: people with TB, healthcare workers, and the public. No psychosocial interventions for people with TB set TB-stigma reduction as their primary or co-primary aim. Eight studies on healthcare workers and the public reported a decrease in TB-stigma attributed to the interventions. Despite the benefits, the interventions were limited by a dearth of validated stigma measurement tools. Three of eight studies with quantitative stigma measurement questionnaires had not been previously validated among people with TB. No qualitative studies used previously validated methods or tools to qualitatively evaluate stigma. On the basis of these findings, we generated a conceptual framework that mapped the population targeted, interventions delivered, and their potential effects on reducing TB-stigma towards and experienced by people with TB and healthcare workers involved in TB care. CONCLUSIONS: Interpretation of the limited evidence on interventions to reduce TB-stigma is hampered by the heterogeneity of stigma measurement tools, intervention design, and outcome measures. Our novel conceptual framework will support mapping of the pathways to impacts of TB-stigma reduction interventions.

Factors affecting the occurrence of otitis media with effusion in preschool and elementary school children: a comparative cross-sectional study.

OBJECTIVE: Identify the risk factors for otitis media with effusion (OME), especially laryngopharyngeal reflux (LPR), adenoid hypertrophy and allergic rhinitis, that could be used to develop prevention strategies in children. DESIGN: A comparative cross-sectional study was conducted to make sure the adequacy of proportions of OME and non-OME cases in finding the related factors. SETTING: History taking, ear/nose/throat (ENT) examination, and tympanometry were performed in preschool and elementary schools. Flexible fibreoptic nasopharyngolaryngoscopy was performed in a bronchoesophagology outpatient clinic in a tertiary referral hospital in Jakarta, Indonesia. PARTICIPANTS: Preschool and elementary children in East Jakarta, Indonesia were recruited for this study. A total of 2016 participants underwent history taking, ENT examination and tympanometry. The case group was 46 children with OME, and the control group was 46 children without OME. The number of subjects fulfilled the minimum sample size for two proportions comparison. MAIN OUTCOME MEASURES: A type B tympanogram indicated OME. A Reflux Finding Score of more than 7 indicated LPR. Adenoid hypertrophy was diagnosed using flexible fibreoptic nasopharyngolaryngoscopy. Allergic rhinitis was diagnosed using a questionnaire based on the International Study of Asthma and Allergies in Childhood phase III that has been validated for Indonesians. RESULTS: The proportion of LPR in the OME group was significantly higher than in the non-OME group, at 78.3% and 52.2%. The probability of OME occurrence in patients with LPR was 3.3 times higher than in patients without LPR (OR 3.3; 95% CI 1.33 to 8.189; p=0.01). There was no significant relationship between adenoid hypertrophy and OME (p=0.211; 95% CI 0.71 to 3.97), and also between allergic rhinitis and OME (p=0.463; 95% CI 0.61 to 4.28). CONCLUSION: The probability of OME occurrence in patients with LPR was 3.3 times higher than in patients without LPR. LPR should be considered in patients with OME and vice versa.

Circadian as a prognostic factor for radiation responses in patients with cervical cancer: A nested case­control study.

The radiation response of cervical cancer is thought to be enhanced by the levels of melatonin due to its roles in the circadian cycle and cancer growth. In the present study, the roles of circadian rhythms and melatonin levels as prognostic factors for predicting the radiation response in patients with cervical cancer were examined. In this nested case­control study, patients with good and poor responses to radiotherapy were assessed in terms of the time­of­day radiation treatment was administered and further influencing factors. The radiation time was determined, as the subjects were either irradiated in the morning (06.00­10.00 am) or afternoon (04.00­06.00 pm). Data on tumour size and other biological parameters were collected and analysed by binary logistic regression. Among the 56 patients examined, most subjects had good radiation responses. Most patients were <50 years old with an initial body weight of >50 kg, no pain prior to radiation, low erythrocyte sedimentation rates, normal intravenous urography results, moderate or good differentiation on pathology and histo­pathologically non­keratinised cells. According to the multivariate analysis, the irradiation time as a surrogate of the circadian cycle (morning vs. afternoon), the initial haemoglobin (Hb) level and the clinical tumour size were significant predictors of the radiation response. The circadian cycle, tumour size and Hb levels may affect the radiation response in patients with cervical cancer. In addition, the morning group had better 5­year overall survival, but it was not significant, possibly due to the small cohort size. Further research is required to identify more relevant prognostic factors using different radiotherapy techniques [National Clinical Trial (NCT) no. NCT05511740, registration date, 08/20/2022].

The effect of MARIKERJA, a fatigue management programme, on the management of fatigue among manufacturing shift workers in Indonesia.

OBJECTIVES: To evaluate the effects of a workplace fatigue management programme called MARIKERJA on reducing fatigue among manufacturing shift workers in Indonesia. METHODS: A quasi-experimental pre- and post-test study was conducted among 116 shift workers (58 in the intervention group and 58 in the control group). The MARIKERJA programme was delivered to the intervention group for 12 weeks. Meanwhile, the control groups received the MARIKERJA intervention only at the end of the study period. Fatigue levels were measured using the Fatigue Severity Scale (FSS) in weeks 6 and 12 of the intervention. Data were analysed using a t test and a general linear model repeated measures procedure. RESULTS: There were significant differences in fatigue scores between the control and intervention groups after the MARIKERJA intervention in week 6 (40.07 ± 8.89 vs. 27.12 ± 11.67; p < 0.001) and week 12 (38.22 ± 9.28 vs. 17.53 ± 6.54; p < 0.001). The MARIKERJA intervention effectively reduced fatigue levels by up to 37.3% (R2 = .373; p = 0.001; 95% CI = 15.82-19.25). CONCLUSIONS: The MARIKERJA intervention effectively reduces fatigue among manufacturing shift workers.

The Role of CYP2B6*6 Gene Polymorphisms in 3,5,6-Trichloro-2-pyridinol Levels as a Biomarker of Chlorpyrifos Toxicity Among Indonesian Farmers.

OBJECTIVES: One of the most widely used pesticides today is chlorpyrifos (CPF). Cytochrome P450 (CYP)2B6, the most prominent catalyst in CPF bioactivation, is highly polymorphic. The objective of our study was to evaluate the role of CYP2B6*6, which contains both 516G>T and 785A>G polymorphisms, in CPF toxicity, as represented by the concentration of 3,5,6-trichloro-2-pyridinol (TCPy), among vegetable farmers in Central Java, Indonesia, where CPF has been commonly used. METHODS: A cross-sectional study was conducted among 132 vegetable farmers. Individual socio-demographic and occupational characteristics, as determinants of TCPy levels, were obtained using a structured interviewer-administered questionnaire and subsequently used to estimate the cumulative exposure level (CEL). TCPy levels were detected with liquid chromatography-mass spectrometry. CYP2B6*6 gene polymorphisms were analyzed using a TaqMan® SNP Genotyping Assay and Sanger sequencing. Linear regression analysis was performed to analyze the association between TCPy, as a biomarker of CPF exposure, and its determinants. RESULTS: The prevalence of CYP2B6*6 polymorphisms was 31% for *1/*1, 51% for *1/*6, and 18% for *6/*6. TCPy concentrations were higher among participants with CYP2B6*1/*1 than among those with *1/*6 or *6/*6 genotypes. CYP2B6*6 gene polymorphisms, smoking, CEL, body mass index, and spraying time were retained in the final linear regression model as determinants of TCPy. CONCLUSIONS: The results suggest that CYP2B6*6 gene polymorphisms may play an important role in influencing susceptibility to CPF exposure. CYP2B6*6 gene polymorphisms together with CEL, smoking habits, body mass index, and spraying time were the determinants of urinary TCPy concentrations, as a biomarker of CPF toxicity.
