Bridging the gap: financing health promotion and disease prevention in Indonesia.

BACKGROUND: Spending on preventive care in low- and middle-income countries (LMICs), including Indonesia, is much lower than spending on curative care. There has been a pressing need to develop a clear pathway to increase spending on preventive care. This study aimed to assess the current financing landscape for health promotion and disease prevention in Indonesia and, subsequently, to develop a framework and recommendations for future health promotion financing in the country. METHODS: We adopted a mixed-method approach to gather information from all relevant stakeholders from December 2022 to June 2023. For the qualitative approach, we conducted (a) in-depth interviews (IDIs) and (b) focus group discussions (FGDs) with government officials at national and district levels, academics, professional organizations, healthcare workers in primary healthcare centres (PHCs), community health volunteers, non governmental organizations and private companies. For the quantitative approach, we applied a national online survey to healthcare workers involved in health promotion in PHCs. IDIs and FGDs were conducted with purposefully selected resource persons at the national level, five selected districts across Indonesia, and within 15 primary health offices and their communities. All qualitative data were recorded, transcribed, coded, interpreted, and then triangulated with national survey findings to develop the financing framework. RESULTS: We identified gaps between the theory and practice of health promotion and disease prevention. These included the limited scope of health promotion initiatives, lack of direction and coordination between ministries, agencies and government levels, limited availability and capacity of health promoters, various yet uncoordinated funding resources and inflexibility in using the funds. To bridge the gap, the framework we developed suggests strengthening the legal and regulatory basis, strategically prioritizing financing arrangements, promoting evidence-based health promotion activities, developing the capacity of health promoters, enhancing the health financing information system and improving monitoring and evaluation. CONCLUSIONS: Identified gaps and challenges in health promotion and disease prevention initiatives inform the development of our framework for future health promotion financing. This framework assists the national government in organizing national health promotion financing strategies and potentially serves as a valuable model for other LMICs.

Vitrification alters growth differentiation factor 9 and follicle-stimulating hormone receptor expression in human cumulus-mural granulosa cells.

Objective: Ovarian tissue vitrification is widely utilized for fertility preservation in prepubertal and adolescent female patients with cancer. The current literature includes reports of successful pregnancy and live birth following autografting. However, the effects of the vitrification process on cumulus-mural granulosa cells (C-mGCs)-somatic cells in ovarian tissue crucial for oocyte maturation and early embryonic development-remain unclear. This study was conducted to explore the impact of vitrification on the cellular function of C-mGCs by quantifying the expression of growth differentiation factor 9 (GDF-9), bone morphogenetic protein 15 (BMP-15), follicle-stimulating hormone receptor (FSHR), luteinizing hormone receptor (LHR), connexin 37, survivin, and caspase 3. Methods: Mature and immature C-mGCs were obtained from 38 women with polycystic ovary syndrome who participated in an in vitro fertilization program. The C-mGCs were then divided into two groups: fresh and vitrified. The expression levels of target genes were assessed using real-time quantitative polymerase chain reaction. Results: After vitrification, GDF-9 expression was significantly decreased among both mature and immature C-mGCs, with 0.2- and 0.1-fold changes, respectively (p<0.01). Similarly, FSHR expression in the mature and immature groups was reduced by 0.1- and 0.02-fold, respectively, following vitrification (p<0.01). The expression levels of the other genes, including BMP-15, LHR, connexin 37, survivin, and caspase 3, remained similar across the examined groups (p>0.05). Conclusion: Vitrification may compromise oocyte maturation through reduced GDF-9 and FSHR expression in C-mGCs after warming.

The Value of Warning Signs From the WHO 2009 Dengue Classification in Detecting Severe Dengue in Children.

BACKGROUND: World Health Organization proposed 7 warning signs to identify the risk of severe dengue in 2009. This study aimed to evaluate the value of these warning signs in detecting severe dengue in children. MATERIAL AND METHODS: A cross-sectional study was conducted utilizing data of children with clinical dengue infection obtained from medical records between January 2009 and December 2018 in Jakarta. Children with confirmed dengue were analyzed and stratified into 3 age groups: infants less than 1 year old, children 1-14 years and adolescents 15-18 years of age. Positive predictive value, negative predictive value (NPV), sensitivity and specificity of each warning sign present or absent on admission in detecting severe dengue were computed. RESULTS: Six hundred ninety-nine children with clinical dengue infection were enrolled, among whom 614 (87.8%) had confirmed dengue infection, either by antigen or antibody serological tests. Severe dengue occurred in 211/614 (34.4%) cases. In infants, important warning signs on admission to detect or exclude severe dengue were liver enlargement (NPV 80.8%) and clinical fluid accumulation (NPV 75%). In children and adolescents, warning sign with highest NPV (in children 76.6% and in adolescents 91.9%) was increase in hematocrit concurrent with a rapid decrease in platelet count. Other warning signs with high NPV values in children were abdominal pain (72%), vomiting (70%), clinical fluid accumulation (69.3%), and in adolescents' abdominal pain (80.7%), vomiting (75.7%), clinical fluid accumulation (82.7%). NPVs increase with more than 1 warning sign in all age groups. CONCLUSION: In infants, liver enlargement or clinical fluid accumulation are important warning signs for severe dengue, when both are absent, severe dengue is unlikely. In older children and adolescents, an increase in hematocrit with the concurrent rapid decrease in platelet count is most discriminative; followed by the absence of abdominal pain, vomiting or fluid accumulation are unlikely severe dengue.

Prospect of Mesenchymal Stem Cells in Enhancing Nerve Regeneration in Brachial Plexus Injury in Animals: A Systematic Review.

Objectives: Brachial plexus injuries (BPI), although rare, often results in significant morbidity. Stem cell was thought to be one of BPI treatment modalities because of their nerve-forming regeneration potential. Although there is a possibility for the use of mesenchymal stem cells as one of BPI treatment, it is still limited on animal studies. Therefore, this systematic review aimed to analyze the role of mesenchymal stem cells in nerve regeneration in animal models of brachial plexus injury. Method: This study is a systematic review with PROSPERO registration number CRD4202128321. Literature searching was conducted using keywords experimental, animal, brachial plexus injury, mesenchymal stem cell implantation, clinical outcomes, electrophysiological outcomes, and histologic outcomes. Searches were performed in the PubMed, Scopus, and ScienceDirect databases. The risk of bias was assessed using SYRCLE's risk of bias tool for animal studies. The data obtained were described and in-depth analysis was performed. Result: Four studies were included in this study involving 183 animals from different species those are rats and rabbits. There was an increase in muscle weight and shortened initial onset time of muscle contraction in the group treated with stem cells. Electrophysiological results showed that mesenchymal stem cells exhibited higher (Compound muscle action potential) CMAP amplitude and shorter CMAP latency than control but not better than autograft. Histological outcomes showed an increase in axon density, axon number, and the formation of connections between nerve cells and target muscles. Conclusion: Mesenchymal stem cell implantation to animals with brachial plexus injury showed its ability to regenerate nerve cells as evidenced by clinical, electrophysiological, and histopathological results. However, this systematic study involved experimental animals from various species so that the results cannot be uniformed, and conclusion should be drawn cautiously.

Mechanism of elevated LH/FSH ratio in lean PCOS revisited: a path analysis.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder affecting 5-20% of reproductive-age women. However, the treatment of PCOS is mainly based on symptoms and not on its pathophysiology. Neuroendocrine disturbance, as shown by an elevated LH/FSH ratio in PCOS patients, was thought to be the central mechanism of the syndrome, especially in lean PCOS. LH and FSH secretion are influenced by GnRH pulsatility of GnRH neurons in the hypothalamus. Kisspeptin is the main regulator of GnRH secretion, whereas neurokinin B (NKB) and dynorphin regulate kisspeptin secretion in KNDy neurons. This study aims to deepen the understanding of the neuroendocrine disorder in lean PCOS patients and its potential pathophysiology-based therapy. A cross-sectional study was performed at Dr. Cipto Mangunkusumo Kencana Hospital and the IMERI UI HRIFP cluster with 110 lean PCOS patients as subjects. LH, FSH, LH/FSH ratio, kisspeptin, NKB, dynorphin, leptin, adiponectin, AMH, fasting blood glucose, fasting insulin, HOMA-IR, testosterone, and SHBG were measured. Bivariate and path analyses were performed to determine the relationship between variables. There was a negative association between dynorphin and kisspeptin, while NKB levels were not associated with kisspeptin. There was no direct association between kisspeptin and the LH/FSH ratio; interestingly, dynorphin was positively associated with the LH/FSH ratio in both bivariate and pathway analyses. AMH was positively correlated with the LH/FSH ratio in both analyses. Path analysis showed an association between dynorphin and kisspeptin levels in lean PCOS, while NKB was not correlated with kisspeptin. Furthermore, there was a correlation between AMH and the LH/FSH ratio, but kisspeptin levels did not show a direct significant relationship with the LH/FSH ratio. HOMA-IR was negatively associated with adiponectin levels and positively associated with leptin and FAI levels. In conclusion, AMH positively correlates with FAI levels and is directly associated with the LH/FSH ratio, showing its important role in neuroendocrinology in lean PCOS. From the path analysis, AMH was also an intermediary variable between HOMA-IR and FAI with the LH/FSH ratio. Interestingly, this study found a direct positive correlation between dynorphin and the LH/FSH ratio, while no association between kisspeptin and the LH/FSH ratio was found. Further research is needed to investigate AMH and dynorphin as potential therapeutic targets in the management of lean PCOS patients.

Association between spinopelvic alignment and the development of degenerative spondylolisthesis: a systematic review and meta-analysis.

INTRODUCTION: Spinopelvic parameter may result in the development of degenerative spondylolisthesis. However, previous studies show conflicting results; some found a significant relationship of some of these parameters with degenerative spondylolisthesis, while others did not. Previously, there was no meta-analysis regarding the association between spinopelvic alignment and degenerative spondylolisthesis. This meta-analysis aims to determine the association between spinopelvic alignment and degenerative spondylolisthesis. METHODS: Systematic reviews and meta-analyses are based on the selected item reporting method for systematic review and meta-analysis (PRISMA). A literature search was performed using PubMed, EMBASE, ScienceDirect, Cochrane, and Google Scholar. Methodological quality is based on the cross-sectional checklist of the Agency for Healthcare Research and Quality (AHRQ) quality check methodology and the Newcastle-Ottawa scale (NOS) for cohort studies. Statistical analysis was performed using Rev-Man 5.3. Subgroup analyses were performed based on ethnicity and study design to ascertain racial relations and heterogeneity. RESULTS: A total of 3236 articles were obtained. Of these, we found that pelvic incidence (mean difference [MD] = 11.94 [1.81-22.08], P = 0.02), pelvic tilt (MD = 4.47 [0.81-8.14]), P = 0.02), and age (MD = 11.94 [1.81-22.08], P = 0.02) were associated with the development of degenerative spondylolisthesis. CONCLUSION: This meta-analysis proves that pelvic incidence, pelvic tilt, and age are associated with degenerative spondylolisthesis.

The effectiveness of self-empowerment-based patient-centered care for obese students in primary services: A randomized controlled trial.

BACKGROUND: Self-empowerment-based patient-centered services with a coaching approach are imperative in the management of students with obesity. This study evaluated the applicability and effectiveness of self-empowerment-based patient-centered coaching for the weight loss program model for obese students. MATERIALS AND METHODS: This randomized control trial recruited 60 obese students aged 17-22 years in Universitas Indonesia from August to December 2021. Intervention group subjects were coached by a health coach. Each health coach assisted four subjects with SMART model coaching in six meetings every 2 weeks through a zoom platform. Both groups had instructions on obesity, nutrition, and physical activity from specialist doctors online. Paired t-test or Mann-Whitney test, as appropriate, to compare the measurements of anthropometry, body composition (bioelectrical impedance analysis), food intake (food record form), physical activity (physical activity form), subjective well-being (subjective well-being questionnaire), and healthy behavior habits (satisfaction scale) between the two groups before and after the intervention. RESULTS: A total of 41 obese students completed the study, 23 from intervention group and 18 from the control group. The change in total body fat (-0.9 [-12.9, 0.70] vs. 0.0 [-6.9, 3.50], P = 0.02) and healthy behavior habit (13.5 ± 11.85 vs. 7.5 ± 8.08, P = 0.04) in the intervention group was significantly greater than in the control group. The change in satisfaction scale of hobby/passion (2 [-4.6] vs. 1 [-2.2], P = 0.02), movement exercise (2.3 ± 2.11 vs. 1.2 ± 1.93, P = 0.03), sleep rest (2 [-6.5] vs. 1 [-3.2], P = 0.01), and spiritual (1 [0.6] vs. 0 [-1.3], P = 0.00) was significantly higher in the coached group. CONCLUSION: A weight loss program for obese students was tested through self-empowerment-based patient-centered care with a coaching approach and has proven to effect changes in anthropometric indicators, body composition, self-empowerment, food intake, and physical activity.

The role of the glucocorticoid receptor and its impact on steroid response in moderate-severe COVID-19 patients.

The effect of corticosteroid therapy in COVID-19 patients is mediated by its suppressive effect on the regulations of inflammatory response. However, its clinical outcome is often unpredictable. This study aimed to explore the role of glucocorticoid receptors in corticosteroid response in Moderate-Severe COVID-19 patients. In this cross-sectional study, we attempted to find the relationship between the expression of the glucocorticoid receptor (encoded by NR3C1), the variation of glucocorticoid receptors isoform, and the mutations of glucocorticoid receptors exon with clinical response to corticosteroids. In addition, the relationship between glucocorticoid receptors expression and the expression of IκBα (encoded by NFKBIA) and glucocorticoid-induced leucine zipper protein (GILZ; encoded by TSC22D3) as steroid pathways was also evaluated. Thirty-four COVID-19 patients were studied. Blood was drawn before and on day 5 of corticosteroid treatment. Glucocorticoid receptors expression, isoform, and mutation were determined by RNA sequencing from white blood cells. Based on the improvement of clinical and oxygen status, patients were classified into responder and non-responder groups. Of thirty-four patients, 23 (67.6%) showed excellent responses to corticosteroids, and 11 (32.4%) were non-responders. The NR3C1 gene expression was significantly higher in the responsive group at baseline and after five days of glucocorticoid treatment. Isoform variant and mutation of glucocorticoid receptors did not correlate with clinical response. The expression of IκBα and GILZ correlated positively with glucocorticoid receptors expression. This study elucidates the relationship between glucocorticoid receptor expression with therapeutic responses to corticosteroids in moderate-severe COVID-19.

General versus spinal anesthesia in percutaneous nephrolithotomy: A systematic review and meta-analysis.

Background: Percutaneous nephrolithotomy (PCNL) is the preferred treatment for the removal of large kidney stones, sized >20 mm. However, there is still an ongoing debate concerning the best anesthesia for PCNL. This study aimed to compare the efficacy and safety between general and spinal anesthesia for PCNL. Methods: A systematic review and meta-analysis study. A systematic, electronic literature search was performed in several databases, including PubMed, Scopus, and Google Scholar until July 1 st, 2022. The quality of the articles was examined using Crombie's Items (for non-randomized controlled trials (RCTs)) and Jadad Scale (for RCTs). The outcomes assessed were operation time, fluoroscopy time, length of stay, stone-free rate, overall complication rate, specific postoperative complications, cost, pain score, and postoperative analgesic requirement. The article selection was reported based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. We assessed four RCTs and eight retrospective studies. Meta-analysis of selected studies was performed using the Review Manager 5.3. Results: General anesthesia resulted in fewer Clavien-Dindo grade II (OR: 0.68; 95% CI: 0.49 - 0.94; p=0.02), major complications (OR: 0.65; 95% CI: 0.45 - 0.94; p=0.02, and lower transfusion rates (OR: 0.70; 95% CI: 0.53 - 0.94; p=0.02). Whereas spinal anesthesia resulted in faster operation time (Mean Difference: -12.98; 95% CI: -20.56 - -5.41; p<0.001, fluoroscopy time (MD: -26.15; 95% CI: -42.79 - -9.50; p=0.002), reduced length of stay (MD: -0.47; 95% CI: -0.75 - 0.20; p<0.001), and lower postoperative analgesic requirement and cost. No significant difference in stone-free rate (OR: 1.08; 95% CI: 0.92 - 1.26; p=0.37). PCNL performed using either general anesthesia or spinal anesthesia is equally safe and effective. Conclusions: Each method of anesthesia has its own advantages and disadvantages. The final choice between general and spinal anesthesia should be based on the patient's condition and surgical team preference.

Mental Health Awareness and Promotion during the First 1000 Days of Life: An Expert Consensus.

The first 1000 days of life constitute a critical phase that will determine the optimum growth and development of a child. An important factor in this phase of life is the perinatal mental health of mothers and children. Mental health awareness is an important public health issue with significant impacts on mothers, spouses, and families, as well as the long-term emotional and cognitive development of children as well. However, the awareness and promotion of mental health within the realms of reproductive health, maternal health, and infant health, i.e., the first 1000 days of life, do not receive high prioritization in Indonesia. Nonetheless, Indonesia, with its existing primary healthcare system, has the potential to raise awareness of and promote the importance of perinatal mental health for its citizens. This experts' consensus proposes several strategies to maximize the usefulness of primary healthcare facilities in Indonesia, including Community Health Centers and Integrated Healthcare Posts, to support perinatal mental health awareness and promotion during the first 1000 days of life. The success of this program, in return, will improve the health status of women and children in Indonesia.

Effect of altitude zone exposure on visuospatial function in military aircrew member.

Introduction: visuospatial is a type of high-level visual perception necessary for identification, information integration, analysing of visual and spatial forms, details, structures and spatial relation. These functions are required in order to successfully complete aviation-related tasks, such as analysing movement, distance perception, and spatial navigation. The aim of this study is to examine whether hypobaric hypoxia can significantly influence changes in visuospatial function, thus increasing the risk of accident or serious incident during flight operation. Methods: this study is a quasi-experiment of pre-post study including before and after hypobaric hypoxia simulated through an altitude chamber. In this study, 42 military aircrews were exposed to different altitude zones at ground level, 10,000 ft (ft) and 25,000 ft respectively, for five minutes. At each altitude zone, the participants were instructed to complete a clock drawing test as a measurement for visuospatial function. The results were analysed using the McNemar non-parametric test. Results: among the 42 subjects, six show impaired visuospatial function at 10,000 ft and 26 participants show it at 25,000 ft. There were significant increased on the proportion of impaired visuospatial function between the ground level to 10,000 ft (p=0.031), 10,000 to 25,000 ft (p=0.0001) and ground level to 25,000 ft (p=0.0001). Conclusion: hypobaric hypoxia may have a significant influence on visuospatial function, starting from as early as 10,000 ft to 25,000 ft. This decrease of visuospatial function could affect human cognitive performance when flying and increase the risk of aviation accidents.

Noncommunicable diseases risk factors and the risk of COVID-19 among university employees in Indonesia.

INTRODUCTION: Noncommunicable diseases (NCDs) are still a major public health problem in Indonesia. Studies have shown that risk factors of NCDs are associated with coronavirus disease 2019 (COVID-19) severity and mortality. However, it is unclear whether NCD risk factors are also risks for new COVID-19 cases. This study aimed to obtain an NCD risk profile among university employees and its associations with contracting COVID-19. METHODS: A cross-sectional study was conducted in October 2021. Participants were administrative employees of Universitas Indonesia (UI), Depok City, West Java. Assessment of NCD risk factors was based on the World Health Organization STEPwise approach to NCD risk factor surveillance (WHO STEPS). Demographic, working, and medical-history data were obtained electronically by using a Google Form. Physical and laboratory examinations were done in the Integrated Post for NCDs. Risks were expressed as adjusted odds ratio (ORadj) and 95% confidence interval (CI) in multivariate analyses. RESULTS: A total of 613 employees were enrolled. Men were predominant (54.8%), and about 36% of them work in shift as security personnel. About 66.7% were overweight or obese and 77.8% had hypertension. There were 138 (22.8%) employees who had COVID-19. Nearly all (95.6%) had been fully vaccinated against COVID-19. At-risk waist circumference (ORadj 1.72, 95% CI 1.15-2.56, p = 0.008) and total cholesterol level of 200-239 mg/dL (ORadj 2.30, 95% CI 1.19-4.44, p = 0.013) were independent risk factors, but shift work (ORadj 0.52, 95% CI 0.34-0.80, p = 0.003) was protective against COVID-19. CONCLUSION: The prevalence of NCD risk factors among university administrative employees was high, increasing the risk of contracting COVID-19. A behavioral intervention program to manage NCD risk factors at the university level is urgently needed according to the Health Promoting University framework.

Assessment of the obesogenic environment in primary schools: a multi-site case study in Jakarta.

BACKGROUND: Childhood overweight and obesity have increasingly been recognized as a significant global public health crisis, including in Asia. This study aimed to assess the obesogenic environment in primary schools in Jakarta, Indonesia. METHODS: A qualitative, multi-site, case study design was used to capture different elements of the school environment and policies related to obesity, with a focus on nutrition and physical activity. An adaptation of the Primary School Environmental Assessment tool was used. Six primary schools in Jakarta were purposively selected based on their location, socioeconomic status, and type (public or private). In addition to direct observation at each school, interviews were conducted with the principal, physical education teacher, canteen staff, street food vendors, and students. RESULTS: Among the six schools, two were private and four were public. The most popular foods consumed by students were unhealthy, such as deep-fried foods and sugar-sweetened beverages. Students had easy and constant access to unhealthy foods, whereas only limited variation of healthy foods were available in the school canteen. Some schools also allowed the student to have access to street food vendors. School policies related to healthy eating and physical activities had been implemented, mainly in the form of teaching these topics as part of the school curriculum. However, promotion of healthy eating and physical activities by the schools was still limited. CONCLUSIONS: This study showed the usefulness of the Primary School Environmental Assessment tool in identifying obesogenic factors in urban area of Indonesia. Effective implementation of guidelines to foster good nutritional practices and healthy lifestyles at school should be prioritized to improve the health and nutritional status of the students.

Knowledge, attitude, and practice related to the COVID-19 pandemic among undergraduate medical students in Indonesia: A nationwide cross-sectional study.

INTRODUCTION: The potential role of medical students in raising awareness during public health emergencies has been acknowledged. To further explore their potentials as public educators and role models for the communities during the coronavirus disease 2019 (COVID-19) pandemic, this study aims to assess the knowledge, attitude, and practice of these students toward COVID-19. METHODS: An online cross-sectional survey was conducted among undergraduate medical students in Indonesia. Socio-demographics characteristics, social interaction history, information-seeking behavior, as well as knowledge, attitude, and practice toward COVID-19 were collected through a self-reported questionnaire. A p-value of <0.05 indicated statistical significance. RESULTS: Out of 4870 respondents, 64.9% had positive attitude and 51.5% had positive practice toward COVID-19, while only 29.8% had adequate knowledge. Knowledge was slightly positively correlated with attitude and practice (ρ = 0.074 and ρ = 0.054, respectively; both p<0.001), while attitude was weakly correlated with practice (ρ = 0.234, p<0.001). Several factors including age, sex, place of residence, institution type, academic level, family income, history of chronic illness, prior volunteering experience, and perceptual awareness on COVID-19 were significantly associated with either knowledge, attitude, and/or practice toward COVID-19. Furthermore, health institution's and the government's press releases, as well as health expert opinions were deemed as the most reliable sources of COVID-19-related information-yet trivially none of these sources were associated with knowledge, attitude, and practice in the study population. CONCLUSION: Many undergraduate medical students in Indonesia had positive attitude and practice against COVID-19, yet only a few had adequate knowledge. This warrants further interventions to keep them updated with COVID-19 evidence to maximize their potentials in raising public awareness on COVID-19.

Retinal abnormalities in universal eye screening of healthy, full-term newborn infants in Jakarta. The incidence and its risk factors: a pilot study.

AIM: To screen for ocular abnormalities in healthy full-term newborn infants using wide-field digital imaging and to analyze factors associated with the findings. METHODS: A total of 1208 full-term newborn infants at a tertiary eye hospital (Cipto Mangunkusumo National Referral Hospital) and a district hospital in Jakarta (Koja Hospital) were enrolled to the study. All eligible newborns underwent fundus examination within 48 h after birth using the RetCam shuttle (Natus Medical Incorporated, USA). Retinal findings were documented and analyzed according to obstetric and neonatal risk factors. RESULTS: Of the 1208 newborn infants enrolled, ocular abnormalities were found in 150 infants (12.4%). Retinal hemorrhage (RH) was the most common finding (88%) in which 2.67% involved the macula, followed by chorioretinitis (4.67%). Univariate analysis showed caesarean section (C-section) (OR 0.27, 95% CI 0.18-0.41, p < 0.001) was a protective factor against RH, while prolonged labor increased the risk of developing RH (OR 1.84, 95% CI 1.24-2.72, p = 0.002). Further multivariate analysis showed similar protective association between C-section and risk of RH (OR 0.29, 95% CI 0.19-0.44, p < 0.001), while other risk factors were not. CONCLUSIONS: Our study showed that universal eye screening in healthy neonates is beneficial in the early diagnosis, monitoring and treatment of ocular abnormalities such as retinal hemorrhage, chorioretinitis and retinoblastoma. Retinal hemorrhage is the most common ocular abnormality and is associated with the delivery method and the duration of labor. Universal eye screening is visual-saving and life-saving for neonates with chorioretinitis, retinoblastoma as well as other abnormalities and should be mandatory in newborn screening.

Integration of symptomatic, demographical and diet-related comorbidities data with SARS-CoV-2 antibody rapid diagnostic tests during epidemiological surveillance: a cross-sectional study in Jakarta, Indonesia.

OBJECTIVES: Affordable options for COVID-19 epidemiological surveillance are needed. Virus detection by reverse transcription-PCR (RT-PCR) is sensitive but costly, and antigen-based rapid diagnostic tests (RDTs) are cheap but with reduced sensitivity; both detect current infection but not exposure. RDT-IgM/IgG antibodies to SARS-CoV-2 detect exposure but have poor sensitivity for current infection. We investigated if the integration of symptomatic, demographical and diet-related comorbidities data with antibody RDTs improves their potential to assess infection rates in addition to exposure, thereby broadening their utility for surveillance. DESIGN: We conducted a cross-sectional study using data from community surveillance for SARS-CoV-2. Health workers collected nasopharyngeal swabs for RT-PCR and RDT antigen assessments and venous blood for RDT-IgM/IgG from symptomatic and asymptomatic persons. Data on age, gender, contact history, symptoms (ie, fever, cough, runny nose, sore throat, headache, dyspnoea and diarrhoea), diet-related comorbidities (ie, diabetes and hypertension) and chest radiology were collected. SETTING: High-risk communities in Jakarta, Indonesia, in May 2020. PARTICIPANTS: 343 community members' data were included. OUTCOME MEASURES: RDT-IgM/IgG sensitivity, specificity and predictive values and area under receiver operating characteristic curve for RT-PCR positivity using RDT results alone and in combination with other predictors, including symptom components derived from principal component analysis. RESULTS: There were 24 PCR-confirmed infections. RDT-IgM/IgG-positive tests were associated with infection (OR 10.8, 95% CI 4.43 to 26.4, p<0.001) with an area under the curve (AUC) of 0.708% and 50% sensitivity, 91.5% specificity, 30.8% positive predictive value (PPV) and 96.1% negative predictive value (NPV). RDT results combined with age, gender, contact history, symptoms and comorbidities increased the AUC to 0.787 and yielded 62.5% sensitivity, 87.0% specificity, 26.6% PPV and 96.9% NPV. CONCLUSIONS: SARS-CoV-2 RDT-IgM/IgG results integrated with other predictors may be an affordable tool for epidemiological surveillance for population-based COVID-19 exposure and current infection, especially in groups with outbreaks or high transmission.

Incidence Rate of Musculoskeletal Injuries among Professional Tennis Players during 2019 International Tournaments in Indonesia.

Several studies have indicated that musculoskeletal injuries are common during a professional tennis competition. However, data from a tropical country like Indonesia is lacking. This study aimed to obtain the incidence rate and injury characteristics and identify risk factors of musculoskeletal injuries among professional tennis players competing in Indonesia under the International Tennis Federation (ITF). The study was a prospective cohort during professional tennis tournaments in Jakarta, Indonesia in 2019, consisting of the ITF Women's Circuit Indonesia (two weeks) and ITF Men's Future Indonesia (three weeks). All athletes were enrolled in this study. Injuries were assessed based on the ITF Consensus Statement. Incidence rate was the number of injuries per 1000 player hours (i.e., the total duration from before the match starts to completion of the match after the final point). The magnitude of risk was expressed as a relative risk (RR) and its 95% confidence interval (CI). Independent risk factors were identified using multivariate analyses. A total of 161 tennis players were enrolled; 71 (44.1%) were men. Their mean age was 22 years old. The incidence rate of musculoskeletal injuries was 30.8 injuries per 1000 player hours (95% CI: 28.2-33.5). The most common onset was acute injuries (61.1%), while the most common location and type of injury was the trunk (38.9%) and muscle strain (61.1%). Risk factors associated with musculoskeletal injury were higher body height, skill level, history of previous injury, and wet bulb globe temperature (WBGT) zone. There was no injury during the doubles matches. Previous injury was an independent risk factor (adjusted RR: 48.1 (95% CI: 11.3-155.0; p < 0.001). The incidence of musculoskeletal injuries among professional tennis player is considerably high. Factors associated with injury are body height, skill level, previous injury, and WBGT zone. Future injury prevention programmes should incorporate the management of previous injuries and take into account the effect of environmental temperature.

Willingness to volunteer and readiness to practice of undergraduate medical students during the COVID-19 pandemic: a cross-sectional survey in Indonesia.

BACKGROUND: The question to involve or restrict medical students' involvement in the coronavirus disease 2019 (COVID-19) pandemic response remains contentious. As their state of preparation and perceptions in volunteering during this pandemic have yet to be investigated, this study aims to evaluate Indonesian medical students' willingness to volunteer and readiness to practice during the COVID-19 pandemic. METHODS: A web-based survey was conducted among undergraduate medical students throughout Indonesia. Socio-demographic and social interaction information, in addition to willingness to volunteer and readiness to practice, were obtained using a self-reported questionnaire. The significance level was set at 5%. RESULTS: Among 4870 participants, 2374 (48.7%) expressed their willingness to volunteer, while only 906 (18.6%) had adequate readiness to practice. Male students, students with prior volunteering experience in health or non-health sectors, and students from public universities or living in Central Indonesia (vs Java) had higher scores of willingness and readiness to volunteer. Students from Sumatra also had better preparedness (odds ratio [OR] 1.56, 95% confidence interval [CI] 1.15-2.12, p = 0.004), while the opposite occurred for students from Eastern Indonesia (OR 0.63, 95% CI: 0.44-0.89, p = 0.002)-when compared to students from Java. In addition, compared to students with high family income, students from lower-middle income families were less willing to volunteer (OR 0.76, 95% CI: 0.59-0.98, p = 0.034), though those with low family income had better readiness (OR 1.51, 95% CI: 1.10-2.08, p = 0.011). Shortage of medical personnel, sense of duty, and solicitation by stakeholders were the main reasons increasing the students' willingness to volunteer; whereas contrarily fear for own's health, absence of a cure, and fear of harming patients were the primary factors diminishing their willingness to volunteer. CONCLUSION: Our findings indicated that many Indonesian medical students are willing to volunteer, yet only few of them were ready to practice, indicating that further preparations are required to maximize their potentials and minimize their exposure to hazards. We suggest that their potentials as a firm support system during the pandemic should not be overlooked, and that the integration of relevant courses to the medical curricula are imperative to prepare for future public health emergencies.
