Development and validation of a pharmacogenomics reporting workflow based on the illumina global screening array chip.

Background: Microarrays are a well-established and widely adopted technology capable of interrogating hundreds of thousands of loci across the human genome. Combined with imputation to cover common variants not included in the chip design, they offer a cost-effective solution for large-scale genetic studies. Beyond research applications, this technology can be applied for testing pharmacogenomics, nutrigenetics, and complex disease risk prediction. However, establishing clinical reporting workflows requires a thorough evaluation of the assay's performance, which is achieved through validation studies. In this study, we performed pre-clinical validation of a genetic testing workflow based on the Illumina Global Screening Array for 25 pharmacogenomic-related genes. Methods: To evaluate the accuracy of our workflow, we conducted multiple pre-clinical validation studies. Here, we present the results of accuracy and precision assessments, involving a total of 73 cell lines. These assessments encompass reference materials from the Genome-In-A-Bottle (GIAB), the Genetic Testing Reference Material Coordination Program (GeT-RM) projects, as well as additional samples from the 1000 Genomes project (1KGP). We conducted an accuracy assessment of genotype calls for target loci in each indication against established truth sets. Results: In our per-sample analysis, we observed a mean analytical sensitivity of 99.39% and specificity 99.98%. We further assessed the accuracy of star-allele calls by relying on established diplotypes in the GeT-RM catalogue or calls made based on 1KGP genotyping. On average, we detected a diplotype concordance rate of 96.47% across 14 pharmacogenomic-related genes with star allele-calls. Lastly, we evaluated the reproducibility of our findings across replicates and observed 99.48% diplotype and 100% phenotype inter-run concordance. Conclusion: Our comprehensive validation study demonstrates the robustness and reliability of the developed workflow, supporting its readiness for further development for applied testing.

Data on undergraduate students' self-regulation in online and blended learning environments during the COVID-19 pandemic in Indonesia.

The COVID-19 outbreak led higher education institutions to shift to distance learning. This article describes data on the self-regulation of undergraduate students in online and blended learning environments during the pandemic situation. A total of 577 students including 144 males and 433 females in Jakarta were recruited using a combination of purposive and snowball techniques. In this non-experimental voluntary survey design, the questionnaire designed by Barnard et al. [1] was adapted to collect data. The online survey was utilized to gather data on personal demographic information (15 items), goal setting (5 items), time management (3 items), environment structuring (4 items), help-seeking (4 items), task strategies (4 items), and self-evaluation (4 items). It was carried out during May and June 2023. The data were analyzed using frequency distributions and correlation analysis. The raw data is available in Excel format. The collected data offer new insights regarding students' self-regulated online learning in terms of gender, academic year, age, daily internet usage, and more. The dataset will guide education policymakers on the role of self-regulatory skills for the success of technology-enhanced learning and educators to design educational programs to increase students' academic performance in online and blended learning contexts.

Attitudes toward e-learning of undergraduate students during COVID-19: Dataset from Indonesia.

This article describes data on students' attitudes toward e-learning at an Indonesian higher education institution during the pandemic period. This cross-sectional study was conducted with a total of 342 full-time students who studied at Universitas Negeri Jakarta in the 2022-2023 academic year. All respondents were determined using the convenience non-probability sampling method. To gather the data, the Attitude Scale Toward E-Learning (ASTEL) developed by Haznedar and Baran [1] was employed. The online survey was distributed to acquire the desired data on individual demographic characteristics (6 items), avoidance of e-learning (10 items), and tendency to e-learning (10 items). It was conducted from February to March 2023 with the support of lecturers. The dataset is available in the form of Microsoft Excel. The collected data provide new insights concerning students' e-learning attitudes with regard to gender, age, grade level, daily duration of internet use, owner of a personal computer, and level of fear of contracting COVID-19. The dataset is made widely accessible to enable more critical and comprehensive investigations. The dataset will provide guidance to lecturers and policymakers in planning the effective use of e-learning and designing appropriate educational programs to enhance students' achievement in technology-supported learning contexts.

Telemedicine vs Face-to-Face for Nursing Home Residents With Acute Presentations: A Noninferiority Study.

OBJECTIVES: Telemedicine and face-to-face outreach services to nursing homes (NHs) have been used to reduce hospital utilization rates for acute presentations. However, how these modalities compare against each other is unclear. This article examines if the management of acute presentations in NHs with care involving telemedicine is noninferior to care delivered face-to-face. DESIGN: A noninferiority study was conducted on a prospective cohort. Face-to-face intervention involved on-site assessment by a geriatrician and aged care clinical nurse specialist (CNS). Telemedicine intervention involved on-site assessment by an aged care CNS with telemedicine input by a geriatrician. SETTING AND PARTICIPANTS: A total of 438 NH residents with acute presentations from 17 NHs between November 2021 and June 2022. METHODS: Between-group differences in proportion of residents successfully managed on-site and mean number of encounters were evaluated using bootstrapped multiple linear regression; 95% CIs were compared against predefined noninferiority margins with noninferiority P values calculated. RESULTS: In the adjusted models, care involving telemedicine demonstrated noninferiority in the difference in proportion of residents successfully managed on-site (95% CI lower limit -6.2% to -1.4% vs -10% noninferiority margin; P < .001 for noninferiority) but not in the difference in mean number of encounters (95% CI upper limit 1.42 to 1.50 encounters vs 1 encounter noninferiority margin; P = .7 for noninferiority). CONCLUSIONS AND IMPLICATIONS: In our model of care, care that involved telemedicine was noninferior to care delivered face-to-face in managing NH residents with acute presentations on-site. However, additional encounters may be required. Application of telemedicine ought to be tailored to fit the needs and preferences of stakeholders.

Motivational Interviewing as an Intervention to Improve Antiretroviral Treatment Initiation among People who Inject Drugs (PWID): A Pilot Study in Jakarta and Bandung, Indonesia.

INTRODUCTION: Progress towards the 95-95-95 target among People Who Inject Drugs (PWID) with Human Immunodeficiency Virus (HIV) infection was considerably low. A behavioral approach, such as motivational interviewing (MI), has been recognized as an effective strategy for improving HIV treatment outcomes among PWID. OBJECTIVE: This study aimed at assessing the impact of MI counselling to improve ARV initiation among HIV-positive PWID. METHODS: A cohort design pilot study was performed, and participants were recruited using a convenience sampling technique. Participants were PWID with HIV who accessed healthcare facilities in two Indonesian cities. Selected participants were assigned to an intervention group and a control group. The intervention group followed MI counselling, while the control group received ART following the standard of care. The participants were assigned to each group based on their preferences. The data was collected between January 2018 and January 2019. RESULTS: In total, 115 PWID with HIV participated in this study in the intervention (n=30) and control (n=85) groups. All but one intervention group's participants started ART, while 68/85 in the control group did so. Receiving MI counselling significantly contributed to ART initiation. In addition, the participants were followed-up until 12 months after ARV initiation. During this period, we found that similar proportions of participants in both groups discontinued the treatment, and only a small number achieved HIV viral suppression. CONCLUSION: The positive effect of MI counselling on ART initiation provides insight into the possibility of its wider implementation. Further studies are needed to gain a deeper understanding of MI counselling and its effect on other outcomes of the HIV treatment cascade.

Psychological dominant stressor modification to an animal model of depression with chronic unpredictable mild stress.

Background and Aim: Chronic unpredictable mild stress (CUMS) is a protocol widely used to create an animal model of depression with food deprivation, water deprivation, and physical-dominant stressors as routine procedures. However, human depression mainly involves psychological stressors and does not always involve a lack of food and water; thus, CUMS procedures should be modified accordingly. Therefore, this study aimed to create an animal model of depression, mainly focusing on a psychologically dominant stressor without food and water deprivation. Materials and Methods: The CUMS and control groups, respectively, received CUMS modification (psychologically dominant stressors without food and water deprivation) for 21 days. A 24-h sucrose preference test (SPT) was used to assess the successful creation of an animal model of depression. Daily food intake measurements, weekly weight monitoring, and weight gain calculations were performed. Either an independent sample t-test or the Mann-Whitney test was used. Results: Of the 42 rats included, 39 completed the study. Chronic unpredictable mild stress procedures for 21 days significantly reduced the SPT (p < 0.05), mean body weight (p < 0.05), and weekly weight gain (p < 0.05) in the CUMS group compared to the control group. However, the weekly average food intake did not statistically differ between the two groups. Conclusion: Psychological dominant CUMS modification to an animal model of depression resulted in lower SPT, body weight, and weekly weight gain in the CUMS group than in the control group.

Quantum Chemical Calculation for Intermolecular Interactions of Alginate Dimer-Water Molecules.

The abundance of applications of alginates in aqueous surroundings created by their interactions with water is a fascinating area of research. In this paper, computational analysis was used to evaluate the conformation, hydrogen bond network, and stabilities for putative intermolecular interactions between alginate dimers and water molecules. Two structural forms of alginate (alginic acid, alg, and sodium alginate, SA) were evaluated for their interactions with water molecules. The density functional theory (DFT-D3) method at the B3LYP functional and the basis set 6-31++G** was chosen for calculating the data. Hydrogen bonds were formed in the Alg-(H2O)n complexes, while the SA-(H2O)n complexes showed an increase in Van der Walls interactions and hydrogen bonds. Moreover, in the SA-(H2O)n complexes, metal-nonmetal bonds existed between the sodium atom in SA and the oxygen atom in water (Na…O). All computational data in this study demonstrated that alginate dimers and water molecules had moderate to high levels of interaction, giving more stability to their complex structure.

Relationship between Parenting Style and Risk of Attention Deficit Hyperactivity Disorder in Elementary School Children.

Background: Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder in a child with three symptoms, which include inattention, hyperactivity and impulsiveness that may persist into adulthood for some conditions. Parenting style is thought to be one part that determines the risk of ADHD in children. This study aims to analyse the relationship between parenting styles and the risk of ADHD in children. Methods: Employing a cross-sectional design, this study was conducted in Surabaya from November 2020 to January 2021. The respondents of the study were parents who had children at risk of ADHD with a total of 55 samples recruited using the purposive sampling technique. The questionnaires used are the demographic questionnaire, Abbreviated Conners Rating Scale (ACRS), and the Parenting Style Questionnaire for Children and Adolescents (KPAA), which were filled out online by the respondents. The data were processed and analysed using the bivariate analysis test, Pearson's chi-squared test, which has a significant value if the P-value < 0.05. Results: The majority of the parents used the authoritative style (94.5%). There was a significant relationship between parenting style and the risk of ADHD in children with P < 0.001 for authoritarian and permissive styles and P = 0.005 for an authoritative style. Conclusion: There is a significant relationship between parenting style and the risk of ADHD in children. This indicates the importance of early diagnosis of ADHD and treating the children with ADHD in the context of family environment, especially from parenting style.

Allopurinol-Induced Stevens-Johnson Syndrome in Javanese Men With Positive HLA-B*58:01.

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.

Lights, camera research! Short film and social media to recruit to HIV research in Indonesia.

Introduction: HIV prevalence among men who have sex with men has increased in Indonesia, amid reports of growing stigma against lesbian, gay, bisexual and transgender individuals and policies that have pushed back public health outreach to these groups. Methods: We assessed the utility of tailored short film and targeted social media engagement to recruit men who have sex with men in Indonesia to HIV social science research. A short HIV testing promotion film, anonymised short survey and invite to a wider research study was embedded on a website platform and disseminated using geo and social/community group targeting for 1 month via a social networking app and social media platforms. Results: From 3 January 2021 to 3 February 2021, there were over 2200 hits of the website within Indonesia. A total of 177 male web users who identified as men who have sex with men or preferred not to declare their sexuality, engaged by watching the short film and completing the survey, they were aged between 17 and 60 years old, of Indonesian nationality and living in Indonesia. Of these, 88% indicated having at least one HIV test in their lifetime, 66% had felt shame with respect to their sexuality and 53% indicated feeling afraid to have a HIV test. Ninety (51%) of the 177 validated using their email or mobile phone number demonstrating willingness to be contacted to join a further study. Twenty-three eligible men who have sex with men, aged 21-55 years old, joined a further social science research study. Participants were from diverse backgrounds and included men born in provinces outside Bali, of different socio-economic and employment backgrounds and diverse relationship contexts. Discussion: Engaging, empowering digital media involving key health messaging can provide health education in more effective ways, build trust and bring communities together. Targeted digital and social media approaches could reach increasingly marginalised and vulnerable communities to promote individual and public health and enable recruitment to valuable medical research.

Implementation of genetic screening test to reduce the incidence of dapsone hypersensitivity syndrome among patients with leprosy in Papua, Indonesia: a study protocol.

INTRODUCTION: The mainstay of leprosy treatment is multidrug treatment (MDT), which contains rifampicin, dapsone and clofazimine. The occurrence of dapsone hypersensitivity syndrome (DHS), a sudden, potentially fatal and traumatic adverse reaction due to dapsone, may affect treatment adherence and may result in fatality if untreated. Before MDT administration, screening for HLA-B*13:01 in patients with leprosy can potentially reduce DHS risk. The study aims to assess the effectiveness of using a screening test for HLA-B*13:01 in reducing the incidence of DHS and to evaluate the feasibility of using the quantitative PCR-based screening tool as DHS predictors before dapsone administration using individual patient testing in a referral centralised-lab model. METHODS AND ANALYSIS: A total of 310 newly diagnosed patients with leprosy will be recruited from health centres in two highly endemic districts in Indonesia. Dried blood will be taken on filter paper as the specimen receptacle to collect DNA from the patients and transported at room temperature to the leprosy referral laboratory before MDT administration. Checking for HLA-B*13:01 from human DNA is performed using the Nala PGx 1301 V.1 kit. The results will be shared with the leprosy health workers on the site via phone call and courier. Patients with a positive test result will be treated with MDT without dapsone, and patients with a negative result will be treated with complete MDT. Physical examination (weight, height, skin, muscle and nerve function examination), complete blood tests (including renal function test) will be carried out at baseline. Follow-up will be performed at the fourth and eighth weeks to observe any development of adverse drug reactions. ETHICS AND DISSEMINATION: The ethical approval for the study was issued by the Ethical Committee of the National Institute of Health Research and Development, Ministry of Health, Indonesia. Written informed consent will be sought from all participants.

Variant landscape of the RYR1 gene based on whole genome sequencing of the Singaporean population.

The RYR1 gene codes for a ryanodine receptor which is a calcium release channel in the skeletal muscle sarcoplasmic reticulum. It is associated with Malignant Hyperthermia (MH) and congenital myopathies including Central Core Disease (CCD), Multiminicore Disease (MMD) and Congenital Fibre-Type Disproportion (CFTD). There is currently little information on the epidemiology of RYR1 variants in Asians. Our study aims to describe the RYR1 variant landscape in a Singapore cohort unselected for RYR1-associated conditions. Data was retrieved from the SG10K pilot project, where whole genome sequencing was performed on volunteers unselected and undetermined for RYR1-associated conditions. Variants were classified based on pathogenicity using databases ClinVar and InterVar. Allele frequencies of pathogenic variants were compared between Chinese, Indians and Malays. Using databases ExAC, GnomAD and GenomeAsia 100k study, we further compared local allele frequencies to those in Europe, America and Asia. Data was analysed using R Commander. Significant P value was set at p < 0.05. Majority of the RYR1 variants were missense mutations. We identified four pathogenic and four likely pathogenic RYR1 variants. All were related to the aforementioned RYR1-associated conditions. There were 6 carriers of RYR1 pathogenic variants amongst 4810 individuals, corresponding to an allele frequency of 0.06%. The prevalence of pathogenic variants was the highest amongst Indians (4 in 1127 individuals) (p = 0.030). Majority of pathogenic and likely pathogenic mutations were missense and located in mutational hotspots. These variants also occurred at higher frequencies in Asians than globally. This study describes the variant landscape of the RYR1 gene in Singapore. This knowledge will facilitate genetic screening for RYR1-related conditions.

Confirmed severe acute respiratory syndrome coronavirus 2 encephalitis in cerebrospinal fluid: a case report.

BACKGROUND: Patients with severe acute respiratory syndrome coronavirus 2 infection show various clinical manifestations, including neurological . Altered consciousness due to severe acute respiratory syndrome coronavirus 2 encephalitis is a very threatening condition if not treated immediately. CASE PRESENTATION: We present the case of a 34-year-old Asian female who tested positive for severe acute respiratory syndrome coronavirus 2 infection using a nasopharyngeal swab sample and presented with acute changes in consciousness without typical respiratory symptoms. Empiric therapy was immediately and simultaneously given with cerebrospinal fluid analysis using polymerase chain reaction, which later also showed positive results for severe acute respiratory syndrome coronavirus 2 infection. CONCLUSIONS: It is important to consider the diagnosis of severe acute respiratory syndrome coronavirus 2 encephalitis when a patient presents with acute altered consciousness and no typical respiratory symptoms. Early empiric therapy can improve patient outcomes.

Antiretroviral drug switches to zidovudine-based regimens and loss to follow-up during the first COVID-19 lockdown in Bali, Indonesia.

OBJECTIVES: International lockdowns during the COVID-19 pandemic impacted antiretroviral drug supplies in Indonesia. We assessed the impact of antiretroviral treatment (ART) provision and being lost to follow-up (LTFU) on people living with HIV, attending a key population-focused HIV clinic in Denpasar, Bali. METHODS: This was a retrospective note review of anonymized data from adult Indonesian patients living with HIV. We collected demographic data and information on being LTFU, and assessed the numbers of patients impacted by ART switches from fixed-dose combination (FDC) tenofovir/lamivudine/efavirenz to multi-pill zidovudine-based regimens, during the first international lockdown from March 2020. RESULTS: Records of 260 Indonesian adult patients registered for HIV care and prescribed ART were reviewed; 240 (92.3%) were men, and 90% were men who have sex with men. Between 13 March and 28 May 2020, 214 (87%) out of 247 patients (previously diagnosed with HIV) had to switch to individual, multi-pill zidovudine-based regimens from their FDC. The switch lasted a mean of 35 days (range 10-85). Twenty-five patients (10%) were LTFU; patients who switched were more likely to remain in care. Data on viral load status and toxicity are lacking as laboratory testing requires self-payment. CONCLUSIONS: The majority of patients living with HIV had no choice but to switch to multi-pill, zidovudine-based regimens. Despite significant efforts to minimize the impact of lockdown on care, 10% of patients were LTFU. Patients switching ART required greater clinic attention and support, improving retention. Complete national data are needed to understand the impact of ART stockouts on virological suppression and drug resistance throughout Indonesia.

How do Positive Deviants Overcome Health-Related Stigma? An Exploration of Development of Positive Deviance Among People With Stigmatized Health Conditions in Indonesia.

A constructivist grounded theory approach was used to understand how some people living with stigmatized health conditions develop positive deviance to overcome stigma. We examined interviews from 13 identified positive deviants living with four different stigmatized health conditions (HIV, leprosy, schizophrenia, and diabetes) in Indonesia. Positive deviance develops in the form of psychological empowerment through improvement of self-belief and perception (intrapersonal component), development of understanding and skill to exert control in life (interactional component), and self-discovery of successful behaviors and strategies to avert stigma (behavioral component). Positive deviants, after being empowered, start empowering others affected by sharing their knowledge and fostering social awareness and acceptance. The findings revealed the presence of problem-solving ability and agency within the community of stigmatized individuals in Indonesia and warrant researchers to partner with the community to expedite the diffusion of transferable positive deviant strategies within and outside the communities.

Validation of a multi-gene qPCR-based pharmacogenomics panel across major ethnic groups in Singapore and Indonesia.

Aim: The clinical utility of pharmacogenomics (PGx) has been gaining traction alongside growing evidence that adverse drug reactions (ADRs) have significant genetic associations. Nala PGx Core® is a multi-gene qPCR-based panel of 20 allele variants, comprising 18 SNPs and two CYP2D6 copy number markers across four pharmacogenes - CYP2C9, CYP2C19, CYP2D6 and SLCO1B1. Methods: In this study, we validated the performance of Nala PGx Core® against benchmark methods, on the Singaporean and Indonesian populations. Results & conclusion: Nala PGx Core® demonstrated robust and accurate genotyping when compared with other established benchmarks. Furthermore, the panel successfully characterized alleles of clinical relevance, such as CYP2D6*10 and CYP2D6*36, across major ethnic groups present of Singapore and Indonesia, suggesting its potential for adoption in clinical workflows regionally.

COVID-19 Likelihood Meter: a machine learning approach to COVID-19 screening for Indonesian health workers

The COVID-19 pandemic poses a heightened risk to health workers, especially in low- and middle-income countries such as Indonesia. Due to the limitations to implementing mass RT-PCR testing for health workers, high-performing and cost-effective methodologies must be developed to help identify COVID-19 positive health workers and protect the spearhead of the battle against the pandemic. This study aimed to investigate the application of machine learning classifiers to predict the risk of COVID-19 positivity (by RT-PCR) using data obtained from a survey specific to health workers. Machine learning tools can enhance COVID-19 screening capacity in high-risk populations such as health workers in environments where cost is a barrier to accessibility of adequate testing and screening supplies. We built two sets of COVID-19 Likelihood Meter (CLM) models: one trained on data from a broad population of health workers in Jakarta and Semarang (full model) and tested on the same, and one trained on health workers from Jakarta only (Jakarta model) and tested on an independent population of Semarang health workers. The area under the receiver-operating-characteristic curve (AUC), average precision (AP), and the Brier score (BS) were used to assess model performance. Shapley additive explanations (SHAP) were used to analyze feature importance. The final dataset for the study included 3979 health workers. For the full model, the random forest was selected as the algorithm of choice. It achieved cross-validation mean AUC of 0.818 {+/-} 0.022 and AP of 0.449 {+/-} 0.028 and was high performing during testing with AUC and AP of 0.831 and 0.428 respectively. The random forest model was well-calibrated with a low mean brier score of 0.122 {+/-} 0.004. A random forest classifier was the best performing model during cross-validation for the Jakarta dataset, with AUC of 0.824 {+/-} 0.008, AP of 0.397 {+/-} 0.019, and BS of 0.102 {+/-} 0.007, but the extra trees classifier was selected as the model of choice due to better generalizability to the test set. The performance of the extra trees model, when tested on the independent set of Semarang health workers, was AUC of 0.672 and AP of 0.508. Our models yielded high predictive performance and may have the potential to be utilized as both a COVID-19 screening tool and a method to identify health workers at greatest risk of COVID-19 positivity, and therefore most in need of testing.

Micronutrient characteristic in recurrent seizure in medicinecontrolled epileptic children with normal nutritional status.

BACKGROUND: Recurrent seizure in epileptic children is correlated with future motoric disorders, behavior problems, and intellectual disabilities. Various factors are thought to modulate the risk of recurrent seizure, including micronutrient status such as calcium, 25-dehydroxycholecalciferol (25-(OH)D), and serum iron presented as hemoglobin level. AIM: To analyze correlation between micronutrient characteristics of epileptic children and recurrence of seizure. METHODS: This cross-sectional retrospective study was conducted in the pediatric clinic of Dr. Soetomo hospital from September to October 2019. Epileptic children with long-term anti-epileptic drugs (AED) for over 6 months and ages ranging 2-18 years were included. Recurrent and non-recurrent group were compared. Age, family history of seizure, and duration of AED administration were noted. Peripheral serum level of hemoglobin, calcium, and 25-(OH)D was measured. The median 25-(OH) D level of both groups were corelated with recurrent seizure by using Spearman test (95% confidence interval). RESULTS: Thirty children were enrolled. Recurrent seizure was occurred in 19 children. There was significant correlation on hemoglobin and calcium, and 25-(OH)D level with the recurrence of seizure (p less then 0.05). Among all observed micronutrients, 25-(OH)D has the strongest correlation (r = 0.750). There was no significant correlation between recurrent seizure and both family history and AED administration duration. CONCLUSION: Micronutrients status is correlated with prevalence of recurrent seizure. Level of 25-(OH)D is strongly correlated, whereas level of hemoglobin, and calcium have weak correlation with recurrent seizure in epileptic children.

Impact of an acute geriatric outreach service to residential aged care facilities on hospital admissions.

INTRODUCTION: Residential aged care facility (RACF) residents frequently present to the emergency department (ED) and are often admitted to hospital. Some presentations and admissions may be avoidable. In 2013, Bankstown-Lidcombe Hospital introduced a subacute geriatric outreach service (SGOS), which had little impact on reducing ED presentations. In 2015, Bankstown-Lidcombe Hospital introduced an acute geriatric outreach service (AGOS), a geriatrician-led team that assesses and treats acutely unwell patients in RACFs. We aim to determine whether the AGOS reduces the risk of hospital admission for RACF residents. METHODS: Hospital admissions data from 2010 to 2019 were used to conduct an interrupted time series (ITS) analysis. AGOS activity data were also summarized. RESULTS: The average number of admissions from RACF per month declined from 42.8 during the SGOS period to 27.1 during the AGOS period. The difference of 15.7 admissions from RACF per month was statistically significant (95% CI 12.1-19.2; P < .001). After the introduction of the AGOS, the risk of admission to our geriatric department from RACFs was reduced by 36.1% (incidence rate ratio =0.64; 95% CI: 0.58-0.71; P < .001) compared to the SGOS period, adjusting for seasonality. DISCUSSION: The AGOS probably reduced the risk of hospital admission for RACF residents.

Wide Application of Minimally Processed Saliva on Multiple RT-qPCR Kits for SARS-CoV-2 Detection in Indonesia.

Saliva as a sample matrix has been an attractive alternative for the detection of SARS-CoV-2. However, due to potential variability in collection and processing steps, evaluating a proposed workflow amongst the local population is recommended. Here, we aim to validate the collection and treatment of human saliva as a direct specimen for RT-qPCR-based detection of SARS-CoV-2 in Indonesia. We demonstrated that SARS-CoV-2 target genes were detected in saliva specimens and remained stable for five days either refrigerated or stored at room temperature. The method of processing saliva specimens described in this report bypasses the need for an RNA-extraction process, thereby reducing the cost, time, and manpower required for processing samples. The developed method was tested across nine commercial kits, including the benchmark, to demonstrate its wide applicability on multiple existing workflows. Our developed method achieved an 86% overall agreement rate compared to paired nasopharyngeal and oropharyngeal swab specimens (NPOP). With the assistance of a saliva sampling device, the collection was found to be more convenient for individuals and improved the overall agreement rate to 97%.
