Abstract Vitamin D deficiency is common in many societies and causes rickets and non-skeletal disorders in children. There are no published data on vitamin D deficiency in Afghanistan. We, therefore, investigated the prevalence and associated factors of vitamin D deficiency in Afghan school children in Kandahar City, Afghanistan. This cross-sectional analytical study was conducted from September 2022 to April 2023 in 510 primary school students aged 6–15 years from six randomly selected schools. Data were analyzed by using descriptive statistics, Chi-square test, and multivariate logistic regression. Of the 510 enrolled children, 54.3% were boys and 91.8% were poor. The mean serum 25(OH)D concentration was 9.3 ng/mL. Vitamin D deficiency (

This work investigates the stability properties of Lyapunov exponents of transfer operator cocycles from a measure-theoretic perspective. Our results focus on so-called Blaschke product cocycles, a class of random dynamical systems amenable to rigorous analysis. We show that prevalence of stability is related to the dimension of the base system's domain, $ \Omega $. When $ \Omega = S^1 $, we show that stability is prevalent among smooth monic quadratic Blaschke product cocycles fixing the origin by constructing a so-called probe. For higher dimensional $ \Omega $, we show that a probe does not exist, thus providing strong evidence that stability is not prevalent in this setting. Finally, through a perturbative method we show that almost every smooth Blaschke product cocycle fixing the origin is stable. [ABSTRACT FROM AUTHOR]

Background: Refractive errors are the most prevalent ocular conditions among adolescents and children. Aim: The purpose of this systematic review and meta-analysis is to evaluate the prevalence of refractive error (RE) among children aged 5–17 years in the Middle East Region. Method: The research adhered to the Preferred Reporting Criteria for Systematic Reviews and Meta-Analyses (2020) in conducting the study. A comprehensive search for relevant studies was conducted on multiple databases. The analysed dataset was classified based on gender and the methods employed to estimate REs. Results: The meta-analysis included data from 38 population-based studies in 11 countries, covering 103 053 children. The overall pooled prevalence rates of myopia, hyperopia and astigmatism were 5.74%, 5.35% and 13.16%, respectively. Females had slightly higher prevalence rates at 7.25%, 5.54% and 15.50%, compared to males at 6.09%, 5.07% and 12.20%, respectively. The prevalence of myopia, hyperopia and astigmatism was higher with cycloplegic refraction at 6.33%, 6.36% and 14.39%, respectively, compared with non-cycloplegic refraction at 4.07%, 2.73% and 9.64%, respectively. Significant heterogeneity was observed between the reviewed studies (p 0.0001). Conclusion: This meta-analysis revealed that astigmatism was the most common RE in Middle Eastern children aged 5–17 years, followed by myopia and hyperopia. There was no significant difference in the pooled prevalence of RE between genders. The findings indicated that myopia, hyperopia and astigmatism measurements varied between cycloplegic and non-cycloplegic refractions. Contribution: These findings concur with the global trend and emphasise the need for deliberate action to address childhood REs in the Middle East.

Prevalence was determined with its 95% confidence interval; associated factors were identified using Fisher’s Exact test, Pearson’s Chi-square, and trend Chi-square. Multivariate adjustment was performed using logistic regression. Analyses were performed using SPSS 29.0.Results: The prevalence of HIV was 5.7%, T. pallidum 0.7%, and co-infection 0.6%. The prevalence of HIV was higher in MSM aged between 24– 40 years (7.5%), with technical or university studies (10.0%), without health insurance affiliation (12.4%), and those who have had a sexual partner with HIV (36.2%). T. pallidum was higher in MSM without health insurance affiliation (3.4%), who had sexual relations with people diagnosed with an STI (5.9%), and a sexual partner with HIV (12.1%). Co-infection was higher in MSM without health insurance affiliation (2.7%), and those who had a partner with HIV (11.2%).Conclusion: Compared with the general Colombian population, MSM have a higher risk of HIV, but are similar to T. pallidum. The identification of the main associated factors in each infection demonstrates the need to prioritize subgroups of MSM that show greater vulnerability to these events. This research demonstrates the urgency of implementing health education strategies in MSM who have a sexual partner with HIV or other STIs. Large gaps were also evident in the magnitude of the three events according to the health insurance affiliation regime, which demonstrates problems of social and health injustice, especially with MSM without health insurance affiliation.Keywords: men who have sex with men, HIV, T. pallidum, syphilis, STI, coinfection, prevalence

Introduction Internationally, the prevalence of diabetes is increasing, and with this comes an increase in diabetes related complications. Diabetic foot disease is the most common lower extremity complication in people with diabetes causing 2% of the global disease burden. It, is associated with major morbidity, mortality, and costs to health services. Despite this burden, the incidence and prevalence of diabetic foot disease is unknown in Ireland. This paper presents a protocol for a systematic review to examine the incidence and prevalence of diabetic foot disease in the Irish population. Methods A systematic review will be performed using the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Pubmed, EMBASE, and Lenus, the Irish Health Research repository, will be searched for publications in any language and without restrictions to date. Title, abstract, and full text screening will be carried out independently by two investigators. Publications reporting on the incidence or prevalence of peripheral neuropathy, peripheral artery disease, ulceration, or amputation in people with diabetes in Ireland, from a defined geographical catchment area of Ireland, will be included. Joanna Briggs Institute (JBI) Critical Appraisal tool will be used to assess included studies methodological quality. Results will be reported in line with the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Conclusion The results of this systematic review can be used to inform appropriate stakeholders on the incidence and prevalence of diabetic foot disease in Irish populations, enabling decision making around appropriate use of resources to help prevent, and improve management of this disease.

Introduction: Tuberculosis is one of the oldest and best-known diseases that has been with mankind for many years. Despite the reduction of infectious diseases in Iran, tuberculosis still remains in some parts of the country, especially in the south of Iran. The aim of this study was the epidemiological investigation of tuberculosis in Sistan and Baluchistan Province. Methods: The current research was conducted cross-sectionally in 2022. The study population included all the patients with tuberculosis in Sistan and Baluchistan Province. Data were collected by census method and using standard checklist. Data analysis was done using SPSS v16 software and descriptive and analytical tests. Results: In this study, the files of 5382 patients with tuberculosis in Sistan and Baluchistan Province were examined. 2489 patients (42.6%) were men. The most affected group were 2309 elderly people (39.5%) and 20 patients (0.34%) with HIV. The number of 4309 patients (73.8%) were suffering from pulmonary tuberculosis. There was a significant relationship between the elderly age group (P=0.04), female gender (P=0.02), non-Iranian nationality (P=0.02), and urban residences (P=0.03) with tuberculosis. However, no significant relationship was observed between marital status (P=0.06) and prison history (P=0.07). Conclusion: The incidence of tuberculosis fluctuated during the five years, but the overall incidence has been decreasing. Considering that some factors such as age groups, gender and symptoms such as cough, weight loss and chest pain increase the chance of contracting the disease. Therefore, doctors of health centers can take an important step in reducing the incidence of tuberculosis with timely visits and regular monitoring of the treatment process of patients.

Introduction: Acute poisoning is one of the critical causes of hospital admission in children worldwide. Understanding the clinico-demographic profile of childhood poisoning will help in developing targeted prevention strategies. This study aimed to find the prevalence of acute poisoning cases among children admitted to a tertiary care hospital. Methods: A descriptive cross-sectional study was done among 4972 children admitted in the pediatric ward, High Dependency Care Unit, and Pediatric Intensive Care Unit of a tertiary care hospital in Nepal. The data were collected from the hospital records from over three years between 1 January 2020 and 31 December 2022 after receiving ethical approval from the Institutional Review Committee. A convenience sampling method was used. Data related to the clinical and demographic data were collected from the patients with acute poisoning and analyzed. Point estimate at 95% Confidence Interval was calculated. Results: Out of 4972 paediatric cases admitted to the hospital, acute poisoning was seen in 57 (1.14%) (0.81-1.39, 95% Confidence Interval) patients. Out of these acute poisoning cases, 31 (54.39%) were accidental. The mean age was 10.10±5.40 years with 35 (61.40%) patients from the adolescent age group. Conclusions: This study conducted in a Nepalese tertiary care hospital identifies acute poisoning as a notable concern among pediatric admissions.

Background: Substance use among adolescents carries a significant public health and socioeconomic burden with potential long-term consequences for the adolescent substance user (SU). Adolescents with mental health challenges are vulnerable to substance use and substance use worsens outcomes in this population. Aim: This study aimed to describe the substance use patterns among inpatients admitted to a specialised tertiary adolescent inpatient unit in Johannesburg over a 4-year period. Setting: This study was conducted at the Tara H. Moross Centre (Tara Hospital), in Johannesburg in the Gauteng province of South Africa. Methods: This was a retrospective comparative record review of all patients admitted to the adolescent unit over the 4 years. Results: A lifetime history of substance use was documented in 44.1% (n = 52) of the 118 patient’s records included in the final analysis. Cannabis was the most frequently used substance (n = 36, 69.2%). There were significant differences between the SU and substance nonuser groups regarding family structure (p = 0.012), family history of substance abuse (p = 0.046) and conflict within the family (p 0.001). Conclusion: The high prevalence of substance use in this sample demonstrates the dual burden of mental health disorders and substance use in an adolescent treatment programme in Johannesburg. Primary caregiver burden and relational difficulties within the family unit should be observed for planned multidisciplinary interventions. Contribution: The findings of this review provide an update on the pattern and prevalence of substance use among this adolescent mental healthcare user group, highlighting potential therapeutic targets.

The mean HbA1c among participants with microalbuminuria was 7.67±0.67%. Conclusions: The prevalence of microalbuminuria among diabetic patients was similar to other studies done in similar settings.

Introduction: Leave against medical advice is a condition in which a patient leaves the hospital against the treating physician's recommendation and is a sensitive issue occurring frequently in neonatal intensive care units across the developing world. Investigating the causes of newborn deaths is essential as there is high neonatal mortality rate in context of Nepal and a huge gap between that rate and desired outcomes. Self-discharge of sick neonates from hospitals further increases the chance of death. Hence, this study aimed to find out the prevalence of leave against medical advice among neonates admitted to the neonatal intensive care unit in a tertiary care centre. Methods: This descriptive cross-sectional study was conducted among patients admitted to the Neonatal Intensive Care Unit from 14 April 2021 to 13 April 2023 after obtaining ethical approval from the Institutional Review Committee (Reference number: 077/78-021). The patient’s demographic and clinical characteristics and reasons for self-discharge were recorded. Convenience sampling was done. Point estimate and 95% Confidence Interval were calculated. Results: Among 1352 neonates, the prevalence of leave against medical advice was 119 (8.80%) (7.29-10.31, 95% Confidence Interval). Conclusions: The prevalence of leave against medical advice from the neonatal intensive care unit was lower than in other studies done in similar settings.

Introduction: Cholecystectomy refers to the surgical removal of the gallbladder. It is indicated in acute cholecystitis, and other complications of gallstones like cholecystitis, pancreatitis and bile duct obstruction, the presence of gallbladder trauma, and gallbladder cancer. The aim of this study was to find out the prevalence of cholecystectomy among patients admitted to the Department of Surgery in a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among patients admitted to the Department of Surgery of a tertiary care centre. Data from 1 July 2021 to 1 July 2022 were collected between 10 February 2023 to 20 February 2023 from the hospital records.

Conclusions: The prevalence of prelabour rupture of membranes was found to be lower than other studies done in similar settings.

Introduction: The discordance in the diagnosis of osteoporosis is characterized by the variation in bone mineral density measurements at different skeletal sites. The presence of discordance significantly alters the treatment plan as different treatment is required for different skeletal sites. The aim of this study was to find out the prevalence of hip-spine discordance in bone mineral densities in patients undergoing dual-energy x-ray absorptiometry scans for suspected osteoporosis. Methods: A descriptive cross-sectional study was conducted among patients undergoing dual-energy x-ray absorptiometry scans from 1 December 2020 to 30 October 2022. Ethical approval was taken from the Institutional Review Committee (Reference number: IRC-2020-11-18-08). Patients undergoing dual-energy x-ray absorptiometry scans for suspected osteoporosis were included. Patients aged less than 50 years, already diagnosed and under treatment for osteoporosis, and incomplete information about T-scores of hips and spine were excluded. Convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated. Results: Among 1028 patients, 602 (58.56%) (55.55-61.57, 95% Confidence Interval) had discordance in hip and spine bone mineral densities. The majority of them, 570 (94.68%) were female and 32 (5.71%) were male. Major discordance was observed in 101 (16.77%) patients and minor discordance was observed in 501 (83.22%) patients. Conclusions: The prevalence of discordance in hip and spine bone mineral densities in patients undergoing dual-energy x-ray absorptiometry scans was higher than that reported in other similar studies done in similar settings.

Conclusions: The prevalence of post-dural puncture headache after spinal anaesthesia in parturients undergoing cesarean section was similar to studies done in similar settings.

Introduction: HIV affects mental health in multiple ways, including its direct pathophysiological effects, associated stigma, impacts on social, and economic dimensions, medications used for long durations and multiple secondary physical health issues that affect the clients and comorbid substance use. In the post-COVID era, in our socio-cultural and geographical context, depression among these populations needs assessment to evaluate their mental health care needs. The objective of this study was to find out the prevalence of depression among people living with HIV/AIDS undergoing antiretroviral therapy at a tertiary care centre. Methods: This was a descriptive cross-sectional study conducted at a tertiary care centre from December 2021 to November 2022 after taking ethical approval from Institutional Review Committee (Reference number: 078/79-006) from the same institute. Convenience sampling method was used. Clients 18 years and above under antiretroviral therapy were included and those acutely medically ill were excluded. The PHQ-9 was used as a self-administered, valid, screening tool for the assessment of depressive symptoms. Point estimate and 95% Confidence Interval were calculated. Results: Among 183 participants, the prevalence of depression was 19 (10.4%) (5.98-14.82, 95% Confidence Interval). Conclusions: Depression was found higher among people living with HIV/AIDS as compared to the other studies done in similar settings. Assessment and timely management of depression could be an important step in improving lives and the effectiveness of HIV/AIDS intervention efforts, ultimately improving access to mental health care and universal health coverage.

Introduction: Anxiety is one of the common mental disorders frequently occurring in the community. It has been a major contributor to public ill health. Very few studies have been conducted on anxiety among academic professionals working in educational institutions. The aim of this study was to find out the prevalence of anxiety among faculty members of academic institutions of a metropolitan city. Methods: A descriptive cross-sectional study was conducted among university faculties working in academic institutions of a metropolitan city from 22 July 2021 to 30 June 2022 after taking ethical approval from the Ethical Review Board (Reference number: 94). A self-administered structured questionnaire was applied to collect the information. Beck Anxiety Inventory was used to measure anxiety; the anxiety was categorised as normal, mild, moderate, and severe and dichotomized into “present” and “absent”. Convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated. Results: Out of 416 respondents, the prevalence of anxiety was found to be 111 (26.68%) (22.44-30.92, 95% Confidence Interval). Among them, 85 (76.58%) were mild, 13 (11.71%) of moderate and 13 (11.71%) of severe type. Among those who had anxiety, 87 (78.37%) were males, and 59 (53.15%) were in the age group of 40 year and above; 37 (33.33%) had chronic health problems. Conclusions: The prevalence of anxiety among faculty members of academic institutions was lower as compared to other studies conducted in similar settings.

Introduction: Chronic liver disease is a common problem worldwide. Spontaneous bacterial peritonitis is a dreaded complication and has high in-hospital mortality. Few studies have been done about the prevalence of spontaneous bacterial peritonitis and associated clinical and biochemical features in a hospital-based population. The aim of this study was to find out the prevalence of spontaneous bacterial peritonitis in chronic liver disease patients with ascites admitted to Department of Medicine in a tertiary care centre. Methods: A descriptive cross-sectional study was done among patients with chronic liver disease with ascites admitted to the Department of Medicine of a tertiary care centre between 18 March 2021 to 28 February 2022 after receiving ethical approval from the Institutional Review Committee (Reference number: PMM2103161493). Convenience sampling method was used. Diagnostic paracentesis was done in every such patient. Point estimate and 95% Confidence Interval were calculated. Results: Among 157 patients, the prevalence of spontaneous bacterial peritonitis was 46 (29.29%) (22.17-36.41, 95% Confidence Interval). The most common presenting symptom was pain abdomen seen in 29 (63.04%). Conclusions: The prevalence of spontaneous bacterial peritonitis in chronic liver disease patients with ascites was similar to studies done in similar settings. Clinicians should be aware that it can present with or without abdominal pain.

Introduction: Chronic obstructive pulmonary disease is a preventable and treatable disease marked by persistent airflow limitation. Abnormal rise of haemoglobin and/or hematocrit in peripheral blood is known as polycythemia which includes increased haemoglobin: greater than 16.5 g/dl in men or greater than 16.0 g/dl in women and increased hematocrit: >49% for men and >48% for women. Men, current smoking, impaired carbon monoxide diffusing capacity, severe hypoxemia, and high altitude living are risk factors associated with an increased risk for secondary polycythemia. Polycythemia contributes to the development of cor-pulmonale and pulmonary hypertension, which are linked to poor prognosis. This study aimed to find out the prevalence of polycythemia among patients with chronic obstructive pulmonary disease admitted to the department of medicine in a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among patients with chronic obstructive pulmonary disease admitted to the Department of Medicine in a tertiary care centre after receiving ethical approval from Institutional Review Committee (Reference number: 153/079/080). The study was conducted from 15 September 2022 to 2 December 2022. Data were collected from the hospital records. A convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated. Results: Among 185 patients, Polycythemia was seen in 8 (4.32%) (1.39-7.25, 95% Confidence Interval) patients among which 7 (87.5%) were females and 1 (12.5%) were male. Conclusions: The prevalence of polycythemia was lower compared to other similar studies done in similar settings.

Introduction: Gallstone is the most common biliary pathology. Once thought of as a disease of the western world, the incidence and burden of cholelithiasis are increasing in Asia. Its literature from Nepal is however still primitive. The study aimed to find out the prevalence of gallstone among patients presenting to the Department of Surgery in a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among patients presenting to the Department of Surgery after receiving ethical approval from the Institutional Review Committee (Registration number: 625). The study was conducted from 1 June 2022 to 1 November 2022. Patients with age more than 18 years were included and patients less than 18 years of age, having common bile duct stones, suffering from biliary malignancy or having an immunocompromised state were excluded. Convenience sampling was done. Point estimate and 95% Confidence Interval were calculated. Results: Among 1700 patients, gallstone was seen in 200 (11.76%) (10.23-13.29, 95% Confidence Interval). Among the 200 patients, 133 of them (66.50%) were females. Multiple gallstones were present in 118 (59%) cases whereas 82 (41%) cases had a single stone. Conclusions: The prevalence of gallstone was found to be similar as compared to other reported literature.

Introduction: Diabetic retinopathy is a specific microvascular ocular complication associated with diabetes. However, retinopathy has also been reported in people with prediabetes. The study aimed to find out the prevalence of diabetic retinopathy among patients with prediabetes attending the outpatient Department of Ophthalmology in a tertiary eye care centre. Methods: A descriptive cross-sectional study was conducted among patients with prediabetes attending the outpatient Department of Ophthalmology in a tertiary eye care centre from 1 January 2022 and 30 April 2022. Ethical approval was obtained from the Ethical Review Board (Registration number: 594/2021 P). All patients had their eyes dilated and examined under the slit-lamp with a 90 D convex lens or indirect ophthalmoscopes with a 20 D lens to find retinopathy. All patients aged 40 to 79 years with intermediate hyperglycemia were included in the study. Convenience sampling was used. Point estimate and 95% Confidence Interval were calculated. Results: Among 141 patients with prediabetes, diabetic retinopathy was found in 8 (5.67%) (1.85-9.49, 95% Confidence Interval). Among which all patients 8 (5.67%) had mild non-proliferative diabetic retinopathy. Among patients with retinopathy, all 8 (5.67%) were obese, 3 (37.50%) were hypertensive, 5 (62.50%) patients had intermediate hyperglycemia for more than 6 months, and 2 (25%) had a family history of diabetes mellitus. Conclusions: The prevalence of diabetic retinopathy in prediabetes patient was found to be higher than the other studies conducted in similar settings.

Background: Excess weight (obesity and overweight) is a pervasive condition that is considered a global epidemic and a threat to public health. Furthermore, numerous changes in fat deposits occur with the advent of menopause, leading to a change in the distribution of body fat. Knowledge of sociodemographic factors and prevalence can inform the effective management of these women. Aim: This study aimed to investigate the prevalence of excess weight among postmenopausal women in Ghana’s Bono East (Techiman) region. Setting: This study was conducted in Bono East regional capital, Techiman, Ghana. Methods: This is a cross-sectional study conducted over 5 months at Bono East regional capital, Techiman in Ghana. Anthropometric parameters such as body mass index (BMI), waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) were obtained using physical measurements while socio-demographic data were gathered using questionnaires. Data analysis was performed using IBM SPSS 25. Results: The mean age of the 378 women who participated in the study was 60.09 ± 6.24 years. Body mass index, WHtR and WHR indicated excess weight of 73.2%, 91.8% and 91.0%, respectively. Education and ethnicity were predictors of excess weight (WHR). Women of the Ga tribe with high school education have 4.7- and 8.6-times increased odds of having excess weight. Conclusions: There are higher prevalence rates of excess weight (obesity and overweight) among postmenopausal women using BMI, WHtR and WHR. Education and ethnicity are predictors of excess weight. Contribution: The study’s findings can be used to develop interventions that focus on addressing excess weight in postmenopausal women within the Ghanaian context.

This study aimed to estimate the prevalence of female sexual dysfunction (FSD) in women with diabetes and/or thyroid disorders and the impact of disease control on the ASEX score.Methods: A cross-sectional study for female patients who had a routine clinic visits was included. The Arizona Sexual Experience Scale (ASEX) was used to evaluate for FSD. Those with a total score of ≥ 19 or scored ≥ 5 on any item or ≥ 4 on three items were considered to have FSD.Results: A total of 253 female patients with a mean age of 39.1 ± 7.3 years were included. Two-thirds of the participants have no FSD. More than half (57.7%) of the participants had a strong desire for sex, and about 20% of the participants were unsatisfied with their orgasm. Compared to those with no FSD, those with FSD had lower BMI (P = 0.375), more likely to have a master’s degree or higher (P = 0.117), diabetes (P = 0.879), hypothyroidism (P = 0.625), diabetes-related microvascular and macrovascular complications (P = 0.049), higher HbA1c, fasting glucose, and TSH (P = 0.731, P = 0.161, and P = 0.561, respectively), lower total cholesterol and LDL (P = 0.368 and P = 0.339, respectively), and exercise more regularly (P = 0.929).Conclusion: FSD was highly prevalent in our study population. Those with type 1 diabetes had the highest ASEX scores. We showed non-significant negative correlations between total ASEX score and both BMI and TSH, as well as a non-significant positive correlation between total ASEX score and both HbA1c and fasting glucose value.Keywords: diabetes mellitus, thyroid disorders, female sexual dysfunction, prevalence

Introduction: Chronic liver disease with cirrhosis is a significant cause of morbidity and mortality not only in developed but also in developing countries.

Results: Among 989 patients, liver cirrhosis in young adults was seen in 200 (20.22%) (18.12-22.32, 95% Confidence Interval). Chronic alcohol use was the primary cause of cirrhosis seen in 164 (82%) cases. The most typical presenting symptom was abdominal distension seen in 187 (93.50%) patients. The most frequent complication was ascites seen in 184 (92%) patients. The most frequent endoscopic finding was gastro-oesophagal varices seen in 180 (90%) patients. There were 145 (72.50%) men and 55 (27.50%) women. Conclusions: The prevalence of liver cirrhosis in young adults was found to be lower than the other studies done in similar settings.

Background: Human immunodeficiency virus (HIV) and psychosis share a complex bidirectional relationship, with people living with HIV being at increased risk of psychosis and those with psychosis at increased risk of HIV. However, people living with severe mental illness often have limited or reduced access to HIV testing and care. Aim: This study aimed to determine the prevalence of HIV and describe the access to HIV testing and care among adult patients with recent-onset psychosis who were admitted to a psychiatric hospital in KwaZulu-Natal (KZN) province, South Africa. Setting: A psychiatric hospital in Pietermaritzburg, KZN province, South Africa. Method: A retrospective chart review of 294 patients with recent-onset psychosis admitted between May 2018 and November 2020. Results: A total of 291 (99%) patients had access to HIV testing during the study period, with the HIV seroprevalence rate being 21.5% among the 294 patients; HIV seropositivity was associated with the 25–49 age category (adjusted odds ratio [aOR] = 3.09, 95% confidence interval [CI] 1.27–7.50), female gender (aOR = 9.55, 95% CI 4.40–20.74), current alcohol and cannabis use (aOR = 3.43, 95% CI 1.01–11.62), family history of psychosis (aOR = 3.22, 95% CI 1.03–10.02) and no tertiary education (aOR = 3.7, 95% CI 0.14–0.99). All those living with HIV were on antiretroviral treatment. Conclusion: This study showed that HIV testing and care was accessible at a psychiatric hospital but the prevalence of HIV in people living with recent onset psychosis remains high. Contribution: The study findings suggest the importance of integrating mental health and HIV management.

Introduction: Anaemia has haemoglobin levels of less than 11/100 ml in the first and third trimesters and less than 10/100 ml in the second. Maternal anaemia is a global health issue that has a negative impact on neonatal outcomes. The prevalence is more common in developing nations like Nepal. Positive correlations have been found between third-trimester maternal haemoglobin and neonatal birth weight. Our study aimed to find out the prevalence of anaemia among third-trimester of pregnant women in a community hospital. Methods: This was a descriptive cross-sectional study conducted in the outpatient Department of Obstetrics and Gynecology from September 2020 to September 2021. Ethical approval was taken from the Nepal health research council (Registration number: 577/2020P). The haemoglobin level of 375 participants was recorded. Data were analyzed using Statistical package for social sciences (SPSS) version 22. Convenience sampling was used. Point estimate and 95% Confidence Interval were calculated. Results: Out of a total of 375 pregnant females in the third trimester, 31 (8.27%) (5.48-11.06, 95% Confidence Interval) were anaemia. Conclusions: The prevalence of anaemia was lower as compared to other studies done in similar settings.

Objective: Burden of disease studies measure the impact of disease at the population level;however, methods and data sources for estimates of prevalence vary. Using a selection of cardiovascular diseases, we aimed to describe the implications of using different disease models and linked administrative data on prevalence estimation within three Australian burden of disease studies. Methods: Three different methods (A = 2011 Australian Burden of Disease Study; B = 2015 Australian Burden of Disease Study; C = 2015 Western Australian Burden of Disease Study), which used linked data, were used to compare prevalence estimates of stroke, aortic aneurysm, rheumatic valvular heart disease (VHD) and non-rheumatic VHD. We applied these methods to 2015 Western Australian data, and calculated crude overall and age-specific prevalence for each condition. Results: Overall, Method C produced estimates of cardiovascular prevalence that were lower than the other methods, excluding non-rheumatic VHD. Prevalence of acute and chronic stroke was up to one-third higher in Method A and B compared to Method C. Aortic aneurysms had the largest change in prevalence, with Method A producing an eight-fold higher estimate compared to Method C, but Method B was 10–20% lower. Estimates of VHD varied dramatically, with an up to six-fold change in prevalence in Method C due to substantial changes to disease models and the use of linked data. Conclusions: Prevalence estimates require the best available data sources, updated disease models and constant review to inform government policy and health reform. Availability of nation-wide linked data will markedly improve future burden estimates. What is known about the topic? Accurate prevalence and subsequent burden estimates that reflect population-level disease burden are an important resource and are necessary for informing health policy decisions and resource distribution. What does this paper add? For cardiovascular disease, the comparison between direct use of linked data and other population-wide data sources highlighted the significant differences in the methods between Australia-wide and Western Australian-based studies in calculating prevalence estimates. What are the implications for practitioners? Continued, effective collaboration for improved disease models and subsequent burden estimates are necessary for appropriately informed decisions about health and resource distribution.

We present two different mechanisms for the emergence of strange attractors (observable chaos) in a two-parameter periodically-perturbed family of differential equations on the plane. The two parameters are independent and act on different ways in the invariant manifolds of consecutive saddles in the cycle. When both parameters are zero, the flow exhibits an attracting heteroclinic cycle associated to two equilibria. The first parameter makes the two-dimensional invariant manifolds of consecutive saddles in the cycle to pull apart; the second forces transverse intersection. The unfolding of each parameter is associated to the emergence of different dynamical scenarios (rank-one attractors and heteroclinic tangles). These relative positions may be determined using the Melnikov method. Extending the previous theory on the field, we prove the existence of many complicated dynamical objects in the two-parameter family, ranging from "lar-ge" strange attractors supporting SRB (Sinai-Ruelle-Bowen) measures to superstable sinks and non-uniformly hyperbolic attractors. We draw a plausible bifurcation diagram associated to the problem under consideration and we show that the occurrence of heteroclinic tangles is a prevalent phenomenon. [ABSTRACT FROM AUTHOR]
