Optimal time-dependent SUC model for COVID-19 pandemic in India
Authors: Hwang Youngjin , Kwak Soobin , Jyoti  , Kim Junseok 
Published: September 2024

AbstractIn this paper, we propose a numerical algorithm to obtain the optimal epidemic parameters for a time-dependent Susceptible-Unidentified infected-Confirmed (tSUC) model. The tSUC model was developed to investigate the epidemiology of unconfirmed infection cases over an extended period. Among the epidemic parameters, the transmission rate can fluctuate significantly or remain stable due to various factors. For instance, if early intervention in an epidemic fails, the transmission rate may increase, whereas appropriate policies, including strict public health measures, can reduce the transmission rate. Therefore, we adaptively estimate the transmission rate to the given data using the linear change points of the number of new confirmed cases by the given cumulative confirmed data set, and the time-dependent transmission rate is interpolated based on the estimated transmission rates at linear change points. The proposed numerical algorithm preprocesses actual cumulative confirmed cases in India to smooth it and uses the preprocessed data to identify linear change points. Using these linear change points and the tSUC model, it finds the optimal time-dependent parameters that minimize the difference between the actual cumulative confirmed cases and the computed numerical solution in the least-squares sense. Numerical experiments demonstrate the numerical solution of the tSUC model using the optimal time-dependent parameters found by the proposed algorithm, validating the performance of the algorithm. Consequently, the proposed numerical algorithm calculates the time-dependent transmission rate for the actual cumulative confirmed cases in India, which can serve as a basis for analyzing the COVID-19 pandemic in India.

Abstract
Background
Current treatment of cannabis-induced psychosis (CIP) focus on the presenting symptoms of individual patient. Therefore, the objective of this study was to investigate the efficacy of pharmacological treatment for CIP in a retrospective manner.

Methods
A retrospective chart review study was conducted at the Princess Mother National Institute on Drug Abuse Treatment (PMNIDAT), Thailand. Patients aged more than 12 years who met the International Classification of Disease-10 (ICD-10) criteria of CIP, had recorded of cannabis use in medical chart, and had positive urine test of cannabis on the first day of admission from October 2013 to September 2019 were enrolled. The primary outcome was the efficacy of pharmacological treatment of CIP. Brief Psychotic Rating Scale (BPRS) on the first day and weekly after receiving treatment were used to assess the primary outcome.

Results
Four hundred and three medical charts with diagnosis of CIP were enrolled into the study and only 317 charts were analyzed. Most of them were male with an average aged of 21.0 (19.0–24.0) years old. All of them used smoked cannabis from dried leaves and flowers of cannabis plant. The presented symptoms on admission were psychosis, mood symptoms, sleep problems, weight loss, and cognitive problems (100%, 64%, 61%, 11%, and 7%, respectively). Baseline BPRS score of the first day of admission was 55.2 ± 9.6. Majority of patients received antipsychotic (98.7%) followed by the combination of antipsychotics with benzodiazepines (34.5.%), antipsychotics with antidepressants (14.4%) and antipsychotics treatment with antidepressants and benzodiazepines (25.9%). Only few patients received antipsychotic monotherapy (17.9%). Risperidone was the most frequently prescribed antipsychotics (83.6%). Mean equivalence dose of risperidone was 8.0 ± 5.9 mg/day. The average hospital length of stay was 28 days (range 22-31). BPRS at 22 days significantly improved compared to the first day of admission (p < 0.001). Schizophrenia was diagnosed in 7% at 1.3 years of follow up.

Conclusion
Antipsychotics was still a key psychotropic drug for treatment of CIP. The symptoms were decreased rapidly and sustained among the treatment period. However, antidepressants and benzodiazepines were commonly used for treatment of other symptoms beyond psychosis.

A study on the development of a fitness age prediction model: the national fitness award cohort study 2017–2021
Authors: Yoon Dong Hyun , Kim Jeong-Hyun , Lee Shi-Uk 
Published: September 2024

Abstract
Background
Physical fitness is considered an important indicator of the health of the general public. In particular, the physical fitness of the older adults is an important requirement for determining the possibility of independent living. Therefore, the purpose of this study was to examine the association between chronological age and physical fitness variables in the National Fitness Award Cohort study data and to develop multiple linear regression analyses to predict fitness age using dependent variables.

Methods
Data from 501,774 (359,303 adults, 142,471 older adults) individuals who participated in the Korea National Fitness Award Cohort Study from 2017 to 2021 were used. The physical fitness tests consisted of 5 candidate markers for adults and 6 candidate markers for the older adults to measure muscle strength, muscle endurance, cardiopulmonary endurance, flexibility, balance, and agility. Pearson’s correlation and stepwise regression analyses were used to analyze the data.

Results
We obtained a predicted individual fitness age values from physical fitness indicators for adults and older adults individuals, and the mean explanatory power of the fitness age for adults was [100.882 – (0.029 × VO2max) – (1.171 × Relative Grip Strength) – (0.032 × Sit-up) + (0.032 × Sit and reach) + (0.769 × Sex male = 1; female = 2)] was 93.6% (adjusted R2); additionally, the fitness age for older adults individuals was [79.807 – (0.017 × 2-min step test) – (0.203 × Grip Strength) – (0.031 × 30-s chair stand) – (0.052 × Sit and reach) + (0.985 × TUG) – (3.468 × Sex male = 1; female = 2) was 24.3% (adjusted R2).

Conclusions
We suggest the use of fitness age as a valid indicator of fitness in adults and older adults as well as a useful motivational tool for undertaking exercise prescription programs along with exercise recommendations at the national level.

Published: September 2024

Abstract
Background
Stakeholder engagement in policy decision-making is critical to inform required trade-offs, especially in low-and-middle income settings, such as many African countries. Discrete-choice experiments are now commonly used to engage stakeholders in policy decisions, but other methods such as best-worst scaling (BWS), a theory-driven prioritization technique, could be equally important. We sought to document and explore applications of BWS to assess stakeholder priorities in the African context to bring attention to BWS as a method and to assess how and why it is being used to inform policy.

Methods
We conducted a literature review of published applications of BWS for prioritization in Africa.

Results
Our study identified 35 studies, with the majority published in the past four years. BWS has most commonly been used in agriculture (43%) and health (34%), although its broad applicability is demonstrated through use in fields influencing social and economic determinants of health, including business, environment, and transportation. Published studies from eastern, western, southern, and northern Africa include a broad range of sample sizes, design choices, and analytical approaches. Most studies are of high quality and high policy relevance. Several studies cited benefits of using BWS, with many of those citing potential limitations rather than observed limitations in their study.

Conclusions
Growing use of the method across the African continent demonstrates its feasibility and utility, recommending it for consideration among researchers, program implementers, policy makers, and funders when conducting preference research to influence policy and improve health systems.

Registration

Examining changes in pain interference via pandemic-induced isolation among patients receiving medication for opioid use disorder: a secondary data analysis
Authors: Frohe Tessa , Janssen Tim , Garner Bryan R. , Becker Sara J. 
Published: September 2024

Abstract
Background
Early in the pandemic, the United States population experienced a sharp rise in the prevalence rates of opioid use, social isolation, and pain interference. Given the high rates of pain reported by patients on medication for opioid use disorder (MOUD), the pandemic presented a unique opportunity to disentangle the relationship between opioid use, pain, and social isolation in this high-risk population. We tested the hypothesis that pandemic-induced isolation would partially mediate change in pain interference levels experienced by patients on MOUD, even when controlling for baseline opioid use. Such work can inform the development of targeted interventions for a vulnerable, underserved population.

Methods
Analyses used data from a cluster randomized trial (N = 188) of patients on MOUD across eight opioid treatment programs. As part of the parent trial, participants provided pre-pandemic data on pain interference, opioid use, and socio-demographic variables. Research staff re-contacted participants between May and June 2020 and 133 participants (71% response rate) consented to complete a supplemental survey that assessed pandemic-induced isolation. Participants then completed a follow-up interview during the pandemic that again assessed pain interference and opioid use. A path model assessed whether pre-pandemic pain interference had an indirect effect on pain interference during the pandemic via pandemic-induced isolation.

Results
Consistent with hypotheses, we found evidence that pandemic-induced isolation partially mediated change in pain interference levels among MOUD patients during the pandemic. Higher levels of pre-pandemic pain interference and opioid use were both significantly associated with higher levels of pandemic-induced isolation. In addition, pre-pandemic pain interference was significantly related to levels of pain interference during the pandemic, and these pain levels were partially explained by the level of pandemic-induced isolation reported.

Conclusions
Patients on MOUD with higher use of opioids and higher rates of pain pre-pandemic were more likely to report feeling isolated during COVID-related social distancing and this, in turn, partially explained changes in levels of pain interference. These results highlight social isolation as a key risk factor for patients on MOUD and suggest that interventions promoting social connection could be associated with reduced pain interference, which in turn could improve patient quality of life.

Effect of a smartphone-based physical intervention on depression, fitness factors and movement characteristics in adults
Authors: Kim Hyungsook , O’Sullivan David Michael 
Published: September 2024

Abstract
Background
Physical activity has been shown to correlate with mental health and a reduction in symptoms of depression. However, the majority of research has focused only on the effects of either aerobic or nonaerobic exercise on depressive symptoms, while the use of novel technological innovations such as mobile phone-based activity programs and their effects on movement characteristics are underrepresented. This study had two objectives: (1) to investigate how effectively 4 weeks of mobile phone-based physical activity can affect depressive scores (CES-10-D and PHQ) and fitness levels and (2) to investigate the whether 4 weeks of mobile phone-based physical activity affected participants’ movement characteristics.

Methods
A total of 31 participants were included and divided into an exercise group (n = 21) and a control group (n = 10). The exercise group was instructed to use a mobile phone-based exercise program 5 times per week for 4 weeks. Pre- and post-exercise, the participants’ depression score (CES-10-D, PHQ9), fitness level (YMCA, grip strength) and movement characteristics (postural sway, movement ROM, movement speeds, etc.) for three Azure Kinect physical activity games based on different fitness factors (balance game, cardiovascular game, reaction game) were measured.

Results
Mixed model ANOVA revealed significant differences between pre- and post-intervention depression scores on the PHQ9 (P = .001) and CES-10-D (P < .001) in both the exercise group and the control group, but not between groups. In terms of movement characteristics, there was an increase in body sway (P = .045) and vertical head movement (P = .02) in the cardiovascular game jogging condition for the exercise group. In the reaction game, the exercise group showed a significant reduction in the number of mistakes (P = .03). There were no other significant differences for the other variables.

Conclusion
The results revealed no differences in the reduction in depression scores between the exercise group and the control group. However, this study showed that a mobile phone-based physical activity intervention affects in-game movement characteristics such as body sway and vertical head movement and therefore may show the potential of using activity-promoting mobile games for improving movement.

Published: September 2024

Abstract
Background
Mental health problems among junior doctors in Malaysia pose a significant concern, as they not only adversely affect their overall well-being but also impact the quality of health services they provide. Therefore, it is important to implement interventions aimed at preserving their mental health. This study aimed to evaluate the effectiveness of the Sanubari Optimal Health Program (OHP) intervention in enhancing the mental well-being of junior doctors in Malaysia.

Methods
The study utilised a quasi-experimental design involving 204 junior doctors who participated in the intervention. The Sanubari OHP Intervention Package was employed alongside self-administered questionnaires for mental health and well-being assessment. To evaluate the effects over time, repeated measures ANOVA was employed to analyse within-group and between-group changes in various endpoints, as measured at different assessment time points.

Results
The study revealed that self-efficacy and adaptive coping behaviours scores increased over time among the intervention group and decreased among the control group. Yet, depression and anxiety scores decreased significantly over time among the intervention group but not in the control group. No significant differences were observed in well-being and maladaptive coping strategies among the groups.

Conclusions
This study showed promising results regarding the effectiveness of Sanubari OHP in improving mental well-being among junior doctors.

Authors: Doan Dung Anh , Vu Nhung Hong , Nguyen Phuong Lan , Nguyen An Duc , Dinh Dai Xuan 
Published: September 2024

Abstract
Objective
To investigate Vietnamese people’s knowledge, attitudes, and experience in purchasing medicines and functional foods online.

Methods
Via an online survey, the data of 1,070 participants were collected, including their general characteristics, Internet use, previous experience, knowledge, and attitudes towards purchasing medicines/functional foods online. Factors associated with their knowledge and attitudes were identified via multivariate linear regression models.

Results
During 2022–2023, about 97.2% of participants used the Internet to seek health information (self-diagnosis: 65.0%, self-medication: 72.6%). Roughly 52.8% bought medicines and/or functional foods online. Among 565 buyers, 41.8% felt satisfied. Only 19.9% understood that selling medicines online was illegal in Vietnam. The main benefits of purchasing medicines/functional foods online that many people agreed on included convenience (87.1%), freedom from location (84.8%), and being able to order/buy products after opening hours (84.7%). Many people felt worried about the ability to buy counterfeit or substandard products (87.7%), inaccurate product information (85.0%), the lack of supervision of the authorities (83.7%), and increasing risks of drug abuse, self-medication, and treatment non-adherence (82.5%). Roughly 84.3% found distinguishing between legal and illegal online pharmacies difficult. Participants’ average knowledge and attitude scores were 6.514 ± 2.461 (range: 0–16) and 89.330 ± 13.720 (range: 23–115), respectively. The main factors associated with people’s knowledge and attitudes towards purchasing these products online included their frequency of Internet use, seeking health information online for self-medication, feeling satisfied with previous experience, and having at least one chronic disease.

Conclusions
Many Vietnamese people’s knowledge about purchasing medicines/functional foods online was limited. With the increasing need for online shopping, enhancing their knowledge is paramount. In the forthcoming years, when the Ministry of Health and relevant authorities publish legal documents and enact laws involving online pharmacies and trading medicines on the Internet, ways to recognize licensed online pharmacies must be widely propagated and disseminated in the community.
The prevalence of occupational injuries and associated risk factors among workers in iron and steel industries: a systematic review and meta-analysis
Authors: Shabani Saumu , Bachwenkizi Jovine , Mamuya Simon Henry , Moen Bente Elisabeth 
Published: September 2024

Abstract
Background
The iron and steel industries are among the most dangerous workplaces in the world compared to other manufacturing industries. Workers are exposed to multiple occupational hazards, which predispose them to high risks of both fatal and non-fatal injuries. Currently, the data on the global prevalence and associated risk factors for occupational injuries in the iron and steel industries is fragmented and incomplete. This study was undertaken to address this issue by pooling data relating to the prevalence of occupational injuries and its associated factors among workers in iron and steel industries studies around the world.

Methods
The search was conducted systematically using PubMed, HINARI, EMBASE and Google Scholar for published studies in English that reported on occupational injuries and associated risk factors among workers in iron and steel industries. MetaXL version 5.3 software was used in the meta-analysis to estimate the pooled prevalence of occupational injuries and associated risk factors among workers in the iron and steel industries. The study protocol has been registered with PROSPERO, number CRD42022344258.

Results
Of the 447 articles identified, 15 studies from 9 countries met the inclusion criteria. The pooled prevalence estimate of occupational injury was 0.55 (95% CI: 0.15, 0.93). The pooled results indicated that the odds of having an occupational injury were 4.06 times higher among workers who did not use personal protective equipment compared to those who used such equipment. Likewise the odds of occupational injuries was increased by 1.65 among night shift workers compared to the counterpart.

Conclusions
The global prevalence of occupational injuries in iron and steel industries was 55%. The results indicate that night work shift and the lack of use of personal protective equipment has a higher impact than other factors in the occurrence of occupational injuries in the iron and steel industries.
Systematic design and evaluation of aptamers for VEGF and PlGF biomarkers of Preeclampsia
Authors: Mallawarachchi Samavath , Cebecioglu Rümeysa E. , Althumayri Majed , Beker Levent , Fernando Sandun , Ceylan Koydemir Hatice 
Published: September 2024

AbstractPreeclampsia is a potentially life-threatening condition for both mother and baby, characterized by hypertension and potential organ damage. Early diagnosis is crucial to mitigate its adverse health effects. Traditional diagnostic methods, which focus on late-manifesting symptoms like hypertension and proteinuria, underscore the need for molecular diagnostic approaches for timely detection. This study successfully designs and evaluates novel aptamers with high specificity and affinity for Vascular Endothelial Growth Factor (VEGF) and Placental Growth Factor (PlGF), biomarkers closely associated with preeclampsia. Using molecular docking, molecular dynamics simulations, and BioLayer Interferometry (BLI), we identified aptamers that demonstrated strong binding affinities, comparable or superior to traditional antibodies. Our findings suggest that these aptamers have the potential to be integrated into cost-effective, point-of-care diagnostic tools, significantly improving early detection and intervention strategies for preeclampsia. The robust performance of these aptamers marks a pivotal step toward the development of more reliable and accessible diagnostic solutions, with implications for better maternal and fetal health outcomes.
Barriers to correct pronoun usage in healthcare settings
Authors: Makara Jodie , Cain Roman , Glock Lucas , Ioerger Michael , Holliday Scott 
Published: September 2024

Abstract
Background
Using correct pronouns is an impactful way to establish affirming environments for transgender and nonbinary (TGNB) patients. However, physicians often report struggling with this.

Objective
This study set out to conduct an initial root cause analysis of factors contributing to medical students and physicians failing to use TGNB patients’ correct pronouns.

Methods
A 10-item Qualtrics survey was sent to medical students, residents, and physicians practicing in Central Ohio. Participants were asked to describe perceived challenges or barriers colleagues have regarding correctly using TGNB patients’ correct pronouns. A directed content analysis of participant responses was performed utilizing a fishbone diagram root cause analysis tool as a basis for conceptualizing and categorizing barriers. All coding was completed by independent reviewers utilizing a consensus reconciliation methodology.

Results
Of 928 survey respondents, 763 met the study inclusion criteria, of which 453 provided analyzable responses. Of these 453, attendings with five or more years of practice (32.5%) and medical students (27.4%) made up the two largest demographic categories. 1.7% of respondents identified as transgender, nonbinary, and/or genderqueer, and 64% identified as heterosexual/straight. Five core barrier categories were identified: documentation, patient care, environment, knowledge, and individuals. Sub-categories were also identified, including lack of documentation, discomfort, medical culture, lack of standardization, prejudice, and assumptions.

Conclusion
The study identifies important barriers to medical professionals correctly using TGNB patients’ pronouns. The root cause analysis conducted as part of this study demonstrates the necessity of multi-pronged, system-level interventions to support ensuring TGNB patients are addressed using the correct pronouns.
