The Relationship between Nomophobia and Learning Motivation Muslim Students in Java

This research aims to assess the level of nomophobia among students and their learning motivation and explore the relationship between these two factors. Utilizing a quantitative methodology with a correlational approach, the study sampled 356 students from across the island of Java through convenience sampling techniques. Data was collected via a nomophobia questionnaire (NMP-Q), which consists of 16 items with a reliability score of .899, and a learning motivation scale with 13 items and a reliability score of .847, distributed through WhatsApp. The data analysis involved quantitative descriptive analysis and Pearson product-moment correlation analysis. The findings reveal that students exhibit a high level of nomophobia while their learning motivation is low. Additionally, there is a significant inverse relationship between nomophobia and learning motivation, indicating that higher levels of nomophobia are associated with lower motivation to learn. Conversely, lower levels of nomophobia correlate with increased learning motivation. These research findings can serve as a foundation for counselors to develop appropriate interventions to address nomophobia and enhance students' motivation to learn.

The Role of Resilience and Defense Styles in Caregiver Burden Among the Mothers of Children with Cancer: A Descriptive-Correlational Study

Background: The diagnosis of childhood cancer can be considered a multidimensional crisis for parents, particularly mothers. Objectives: This study aimed to determine the predictive role of defense styles and resilience in the caregiver burden experienced by mothers of children with cancer. Methods: This descriptive-analytical study focuses on mothers of children with cancer who were hospitalized in the pediatric wards of Seyed al-Shohada Hospital in Isfahan, Iran. A total of 136 participants were selected using convenience sampling. The study utilized the Defense Styles Questionnaire (DSQ-40), the Zarit Burden Scale (ZBS), and the Connor-Davidson Resilience Scale (CD-RISC) to collect data. The data were analyzed using STATA16. Results: On average, mothers had a caregiver burden score of 38.65 and a resilience score of 93.51. The majority of mothers (62.5%) exhibited neurotic defensive styles. The regression test results indicated a significant inverse relationship between caregiver burden and resilience (P = 0.002), as well as a significant relationship between the child’s sex and caregiver burden (P < 0.05). Conclusions: Based on the study's findings, it is recommended that counseling and psycho-cognitive programs be designed, developed, implemented, and evaluated to enhance the resilience of mothers of children with cancer and thereby reduce their caregiver burden.

Elevation-Dependent Snow Cover Dynamics and Associated Topo-Climate Impacts in Upper Indus River Basin

In the present study, Improved Moderate Resolution Imaging Spectro-radiometer (MODIS) snow cover product (MOYDGL06*) has been used to evaluate the snow cover area (SCA) in Kabul, Jhelum, and Indus river basins for the time period of 2003 – 2020 with available MODIS land surface temperature (LST), and CHIRPS (precipitation) with objectives to evaluate the spatio-temporal SCA, and climate variables with respect to different elevations analyzed from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model Version 3 (GDEM v3) and also to correlate the climatic variables with SCA. The results presented average annual SCA is around 50.7% – 64.7% in sub-basins of UIB, further it has been observed that SCA is decreasing on annual and seasonal timescale in all three basins. Elevation-dependent SCA, temperature, and precipitation presented a mix of trend on annual, seasonal, and monthly timescale at lower and higher altitude in all selected basins. Moreover, it was noticed that topography (slope, & aspect) also influences the SCA in the region. Furthermore, it has been examined that temperature has significant inverse relationship with SCA at middle and higher altitude in Indus, while in Kabul, and Jhelum no significant relationship observed at extreme lower and higher altitudes. It is also evident from relationship between SCA and climate variable that temperature is significantly responsible for decreasing trend of SCA rather than intense precipitation in all three river basins. Thus, all these elevation-dependent changes can improve our hydrological understanding which can have a considerable implication for hydrology, climate science, water resource management and socio-economic activities.

Unveiling the effect of non-performing loans on lending behaviour: Evidence from Vietnam’s banking system

This study shows how non-performing loans (NPLs) and other variables specific to banks affect loan growth and the risk-weighted composition of assets in the Vietnamese banking sector. We use a large panel dataset of Vietnamese commercial banks from 2008 to 2022 and different econometric estimators to look at how NPLs, loan loss provisions (LLPs), and bank-specific factors affect how banks lend money. Additionally, we conduct a sensitivity analysis to bolster the robustness of our empirical findings. Our analysis reveals a statistically significant inverse relationship between NPLs/LLPs and loan growth rates, underscoring the critical role of effective credit risk management. Furthermore, institutional characteristics such as bank size, liquidity position, profitability metrics, and tangible asset ratios substantially influence lending patterns and risk exposure. Conversely, macroeconomic and broader institutional factors demonstrate mixed effects, with many exhibiting statistical insignificance. This study addresses a notable gap in the extant literature concerning the determinants of bank lending behaviour in Vietnam, offering nuanced insights into the role of credit risk indicators and bank-specific attributes. Our findings yield substantial implications for regulatory bodies, policymakers, and banking executives in their pursuit of enhancing the stability and operational efficiency of Vietnam's financial system. By elucidating these relationships, our research contributes to the ongoing discourse on banking sector dynamics in emerging economies. It provides an empirical foundation for informed decision-making in financial policy and risk management strategies.

Exploring the relationship between gut microbiota and breast diseases using Mendelian randomization analysis

BackgroundGrowing evidence suggests a relationship between gut microbiota composition and breast diseases, although the precise nature of this association remains uncertain. To investigate the causal relationship between gut microbiota and breast diseases, we utilized two-way Mendelian randomization (MR) analysis.MethodsFour common diseases were included as outcomes: breast cancer, breast cysts, inflammatory disorders of the breast, and infections of the breast associated with childbirth, along with their subtypes. Genetic data on gut microbiota were extracted from genome-wide association studies (GWAS). The primary approach used to investigate the association between these genetic factors and gut microbiota was the inverse-variance-weighted (IVW) method with random-effects types. Sensitivity analyses, such as Cochran’s Q test, the MR-Egger intercept test, and leave-one-out analysis, were conducted to ensure the stability and reliability of the MR findings.ResultsWe discovered plausible causal links between 20 microbial categories and the breast diseases, with a significance level of p < 0.05. Notably, Family.Rikenellaceae (p: 0.0013) maintained a significant inverse relationship with overall breast cancer (BC), after the Bonferroni correction. In the reverse MR analysis, interactions were observed between Genus.Adlercreutzia and estrogen receptor-positive cancer. In addition, Genus.Sellimonas, Family.Rikenellaceae, and Genus.Paraprevotella were associated with ER+ and overall breast cancer, whereas Genus.Dorea was linked to both estrogen receptor-negative and overall breast cancer. Family.Prevotellaceae was the only category correlated with inflammatory breast disorders. Moreover, Genus Eubacteriumruminantiumgroup, Genus.Lactococcus, and Family.Alcaligenaceae were associated with breast cysts, while Genus.Anaerofilum, Genus.Butyricimonas, Order.Coriobacteriales, Order.Pasteurellales, and Order.Verrucomicrobiales showed significant associations with infections of the breast associated with childbirth. No evidence of heterogeneity or horizontal pleiotropy was found.ConclusionOur Mendelian randomization analysis confirmed a causal relationship between gut microbiota and breast diseases. Early stool tests may be a viable method for screening diseases to identify people at higher risk of breast diseases.

Optimal sites for mini-implant insertion into the infrazygomatic crest according to different craniofacial morphologies: A cross-sectional cone-beam computed tomography study

The infrazygomatic bone crest and other extraalveolar regions represent a viable option for the placement of temporary anchorage devices when distalizing the maxillary arch. This approach allows for the movement of the dentition without concern for potential collisions among dental structures. Nevertheless, it is of the utmost importance to conduct a thorough examination of the anatomy of this region before the placement of mini-implants to prevent potential injuries, such as maxillary sinus perforations. The objective of this study was to quantify the depth of the infrazygomatic crest and evaluate its correlations with age, gender, skeletal classification, and vertical pattern. The study sample of this cross-sectional, retrospective study consisted of 201 cone-beam computed tomography scans collected from patients treated at the master's program in orthodontics at the University of Valencia and at a private dental clinic. The cone-beam computed tomography scans were collected for 5 years, from January 2017 to May 2022. The total and intraalveolar lengths were defined and measured at 3 points: the distal roots of the maxillary second molars, the distal roots of the maxillary first molars, and the mesial roots of the maxillary first molars. These measurements were taken on both the right and left sides using the Carestream 3D Imaging System (Atlanta, Ga). The total length (TL) at the mesiobuccal level of the first molars was found to be significantly longer on both sides (P= 0.001). The intraalveolar length exhibited statistically significant differences between the right and left sides, with those of the left side exhibiting greater length (P<0.001). The normodivergent patterns demonstrated lower TL values than hypodivergent (P= 0.006) and hyperdivergent patterns (P= 0.033). A statistically significant inverse relationship was observed between the distance from the cementoenamel junction to the vestibular bone crest and the total and intraalveolar lengths in the studied regions. The TL was greatest in the region of the mesiobuccal root of the maxillary first molars, followed by the region of the distal root of the second molars, and finally, the region of the distobuccal root of the maxillary first molars. Patients with normodivergent patterns exhibited the lowest total infrazygomatic ridge height.

Association between dietary carotenoids intake and fecal incontinence in American adults: evidence from NAHNES 2005-2010.

Carotenoids represent a class of bioactive compounds with potential implications for gut health. However, the relationship between dietary carotenoid intake (DCI) and fecal incontinence (FI) remains unclear. This study aims to elucidate the association between DCI and the risk of FI. Participants aged 20 and above from the National Health and Nutrition Examination Survey (NHANES, 2005-2010) were included in the study. Data on FI were derived from the bowel health questionnaire, while DCI information was obtained from dietary interviews. Survey-weighted logistic regression analysis and restricted cubic splines (RCS) were employed to evaluate the relationship between DCI, its subtypes, and FI. Weighted quantile sum (WQS) regression was utilized to assess the overall effect of DCI and its predominant subtypes. Finally, subgroup analyses were conducted. The study included a total of 11,915 participants, of whom 1,023 (7.0%) experienced FI. Logistic regression analysis revealed that, after adjusting for all covariates, there was a significant inverse association between DCI and the risk of FI (Model 2: Q4 vs. Q1, OR = 0.67, 95% CI: 0.52-0.86, p = 0.003). However, among the DCI subtypes, only β-carotene was found to have a significant inverse relationship with FI (Model 2: Q4 vs. Q1, OR = 0.68, 95% CI: 0.52-0.88, p = 0.005). The RCS curves indicated no non-linear relationship between DCI, its subtypes, and FI (all p-non-linear >0.05). WQS analysis identified β-carotene (weight 38.2%) and lutein/zeaxanthin (weight 27.8%) as the primary contributors. High levels of carotenoid intake, particularly β-carotene and lutein/zeaxanthin, are associated with a reduced risk of fecal incontinence. This discovery provides dietary recommendations for patients suffering from FI.

The nonlineard association between triglyceride to HDL cholesterol ratio and long-term heart disease risk: findings from China Health and Retirement Longitudinal Study (CHARLS)

ObjectiveThe aim of this study was to investigate the relationship between triglyceride to high-density lipoprotein cholesterol ratio (TG/HDL-C) and the risk of cardiovascular disease (CVD) in middle-aged and elderly Chinese population. CVD has high morbidity and mortality in China, with 5.09 million CVD deaths in 2019 and a mortality rate of 364.5 cases per 100,000 people. Existing studies have focused on specific populations and lack studies on the general population.MethodsThis study used data from the China Health and Aged Care Tracking Survey (CHARLS) to analyse the middle-aged and elderly population between 2011 and 2020. The exposure variable was TG/HDL-C ratio, the outcome variable was the occurrence of heart disease (including myocardial infarction, coronary heart disease, etc.), and the covariates included age, gender, education level, and body mass index. The final sample size was 4,551 participants. Weighted Cox regression models were used to assess the association between TG/HDL-C and CVD risk, and nonlinear associations and stratified analyses were performed.ResultsThe results demonstrated a significant association between TG/HDL-C ratios and cardiac morbidity, with a risk ratio of 0.71 (95% CI: 0.71–0.71) in the adjusted model II. Nonlinear analysis revealed a threshold effect. Within the TG/HDL-C 0.15–1.5 interval (inflection point LnTG/HDL-C 0.41), each 1-unit increase in Ln (TG/HDL-C) was associated with a 17% reduction in the risk. The inflection point was associated with a 0.83-fold reduction in the risk of CVD (95% CI: 0.75, 0.92; p = 0.0003), but beyond this point, the association was no longer significant (1.00-fold reduction in risk; 95% CI: 0.95, 1.05; p = 0.9701). In contrast, stratified analyses demonstrated that the results were more applicable to women and those younger than 65 years.ConclusionIn summary, the study found a significant inverse relationship between the triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio and the risk of cardiovascular disease in the middle-aged and elderly Chinese population, with a nonlinear threshold effect observed at a TG/HDL-C ratio of around 1.5.

Assessment of PM2.5 pollution features and health advantages in Northwest China.

The elevated concentration of suspended particulate matter in the atmosphere is closely associated with the morbidity and mortality of human diseases. In northwest China, fine particulate matter pollution has persistently affected local health, production, and daily life due to climatic factors and economic development. This paper first examines the distribution and variation of PM2.5 concentrations in northwest China from 2013 to 2022 to understand changes in PM2.5 exposure levels, as well as their associated health and economic benefits since the implementation of the "Air Pollution Prevention and Control Action Plan." Second, we estimated the number of premature deaths in the research region under various control scenarios based on PM2.5 concentrations recorded in 2013 and 2021, utilizing existing epidemiological studies for reference. Finally, we calculated the financial benefits resulting from variations in PM2.5 concentrations within this region. Results indicated that (1) from 2013 to 2022, the Tarim Basin exhibited the highest PM2.5 concentration among all studied areas, while northern Xinjiang and Qinghai Province had notably lower levels. Additionally, wintertime concentrations were consistently higher than those observed during summer months; however, there has been a general trend toward reduced PM2.5 content over the past decade. (2) A significant inverse relationship was found between premature mortality rates and PM2.5 concentrations; specifically, fluctuations in PM2.5 levels exerted a more pronounced impact on premature deaths attributable to cardiovascular diseases compared to respiratory conditions within this northwest region. (3) Males were disproportionately affected by increases in PM2.5 concentration relative to females-experiencing two to three times more early fatalities than their female counterparts did. (4) Over a 9-year period within this research area, fiscal benefits derived from interventions targeting PM2.5 treatment increased by approximately 891 million yuan.

Beyond the counter: unveiling the financial informality dynamics of female entrepreneurs in Lima’s Bodega sector

PurposeThis study examines the interrelations among educational level, financial literacy, financial inclusion and informal financial business practices of female entrepreneurs in Lima, Peru, focusing on their intentions toward business formalization. Additionally, it explores the influence of legal formalization on both business formality and tendencies toward informality intentions.Design/methodology/approachThe methodology involved a self-administered survey among 118 female entrepreneurs in the small vendor “Bodega” sector, with statistical analysis conducted via partial least structural equation modeling.FindingsThe study’s outcomes validated the significant role of financial literacy and inclusion as mediators between educational level and formalization intentions. Notably, legal formalization did not significantly alter these dynamics.Research limitations/implicationsLimitations arise from the study’s explanatory power and lack of predictive capability for all dependent variables, likely due to sample specificity. Additionally, the quantitative research approach does not allow for a deeper understanding of these phenomena.Practical implicationsWe advocate reevaluating prevailing attitudes toward legal formality and informal practices, emphasizing tailored public policies for older female entrepreneurs and access to formal financing independent of legal registration. This underscores the need for enhanced educational levels for young women and coordinated efforts among institutional actors to more effectively promote formality.Originality/valueThis research contributes original insights into the emphasis on informal practices over mere legal registration, especially pertinent to female entrepreneurship. It also highlights the counterintuitive significant inverse relationship between age and formalization intentions, enriching the discourse on entrepreneurial motivation.

Impact of baseline dietary quality on the efficacy of a dietitian-guided weight reduction program

AimThis pre-post intervention study aimed to assess the relationship between baseline dietary quality and the efficacy of a dietitian-guided weight reduction program, which has not been thoroughly documented to date.MethodsNinety-two consecutive obese or overweight patients visiting a tertiary center clinic for weight reduction were enrolled in this study. Participants received a dietitian-guided weight reduction education program aimed at reducing daily caloric intake by 500 kcal and improving adherence to the Mediterranean diet for 3 months. Baseline dietary quality was assessed using the 14-item Taiwanese Mediterranean Diet Adherence Screener (T-MEDAS), where a higher T-MEDAS score reflects greater adherence to the Mediterranean diet. Additional covariates, including dietary behaviors, lifestyle factors, and comorbidities were also recorded. The primary outcome was the percentage of weight reduction at 3 months, analyzed using restricted cubic spline models and generalized estimating equations (GEE) to account for the correlation between weight change and the baseline T-MEDAS scores.ResultsThirty-nine participants were excluded due to major illnesses, use of anti-obesity medications, or loss to follow-up. Among the remaining 53 participants (mean age 41.2 ± 12.8 years, 56.6% female), the average weight reduction was 3.9 ± 3.3% from a baseline weight of 98.5 ± 12.8 kg. Participants who did not achieve a weight reduction of more than 5% had higher baseline T-MEDAS scores compared to those who did (5.4 ± 1.7 vs. 4.1 ± 1.8, p = 0.026). A restricted cubic spline model, adjusted for covariates including age, gender, diabetes mellitus (DM), dyslipidemia, and smoking, revealed a significant inverse relationship between higher baseline T-MEDAS scores and weight loss. After controlling for various confounders, GEE analysis demonstrated that higher baseline T-MEDAS scores were significantly associated with less weight loss (beta: -4.1, 95% CI: -5.6 to -2.6, p < 0.001).ConclusionsHigher baseline dietary quality was associated with reduced effectiveness of a dietitian-guided weight reduction program. This suggests that additional strategies may be required to improve the success of weight loss interventions in individuals with higher baseline dietary quality.

Persistent Calcium Inadequacy in Korean Adults over 20 Years: Analysis of the 1998-2018 Korea National Health and Nutrition Examination Survey.

Calcium inadequacy in Asian populations has been well documented, but whether it has improved over time remains uncertain. We analyzed dietary calcium intake and its association with osteoporosis prevalence over a 20-year period in 48,653 adults (21,932 men and 26,721 women, aged 19 years and older) in Korea, using data from the first to the seventh Korea National Health and Nutrition Examination Survey (1998-2018). Over the past 20 years, Korean adults consistently fell short of the recommended dietary calcium intake, with women and older adults particularly affected, typically consuming only 40-80% of the recommended levels. The 30-49 age group had the highest calcium intake (497-568 mg/day), while those aged 75+ had the lowest (319-457 mg/day). A significant inverse relationship was found between calcium intake and osteoporosis risk, with lower calcium intake associated with higher odds of developing osteoporosis, as determined by both physician diagnoses and bone mineral density measurements (p < 0.001). Notably, over the past 20 years, 68-70% of dietary calcium consistently came from plant-based foods. This study strongly emphasizes the urgent need to enhance calcium-rich food availability and implement targeted interventions to increase calcium intake among those most affected by inadequacy, particularly the elderly and women. Further research with recent data would be valuable for understanding current intake levels and evolving nutritional needs.

Contrasting the Effects of Aspartic Acid and Glycine in Free Amino Acid and Peptide Forms on the Growth Rate, Morphology, Composition, and Structure of Synthetic Aragonites.

Corals and mollusks produce aragonite skeletons and shells containing highly acidic proteins, rich in aspartic acid (Asp) and glycine (Gly). These biomolecules are pivotal in controlling biomineral formation. We explore the effects of l-Asp, Gly, and two peptides: glycyl-l-aspartic acid (Gly-Asp) and tetra-aspartic acid (Asp4) on the precipitation rate, crystal morphology, and CO3 group rotational disorder (inferred from Raman spectroscopy) in aragonite precipitated in vitro at the approximate pH, [Ca2+], and Ωar occurring in coral calcification media. All of the biomolecules, except Gly, inhibit aragonite precipitation. Biomolecules are incorporated into the aragonite and create CO3 group rotational disorder in the following order: Asp4 > Asp = Gly-Asp > Gly. Asp4 inhibits aragonite precipitation more than Asp at comparable solution concentrations, but Asp reduces aragonite precipitation more effectively than Asp4 for each Asp residue incorporated into the aragonite. At the highest solution concentration, the molar ratio of Asp4:CaCO3 in the aragonite is 1:690. We observe a significant inverse relationship between the aragonite precipitation rate and aragonite Raman spectrum ν1 peak fwhm across the entire data set. Tetra-aspartic acid inhibits aragonite precipitation at all concentrations, suggesting that the aspartic acid-rich domains of coral skeletal proteins influence biomineralization by suppressing mineral formation, thereby shaping skeletal morphology and preventing uncontrolled precipitation.

Investigating the relationship between the anxiety of contracting corona virus and the symptoms of obsessive-compulsive disorder with the mediating role of mental confusion and emotion regulation in health care center employees

Introduction: anxiety caused by the Corona virus transmission are highly prevalent among medical staff, so this study aims to determine the relationship between the anxiety of affected by infectious diseases and the symptoms of obsessive-compulsive disorder with the mediating role of mental confusion and emotion regulation. MethodS and Materials: This study was carried out based on correlational method in the form of modeling of structural equations, in which 350 male and female employees working in the health and treatment centers of Neyshabur city were selected through available sampling. Data collection tools included Madsley Practical Obsession Scale, Corona Alipour Anxiety Questionnaire, Criver, Solly and Esomil's Deliberate and Automatic Disorientation Questionnaire, and Gross and John's Emotion Regulation Questionnaire. After completing the questionnaires, data analysis using Modeling of structural equations was done with Lisrel and SPSS softwares. Results: between the anxiety and obsessive symptoms with r = 0.576, between mental confusion and obsessive symptoms with r = 0.553, between mental confusion and anxiety with r = 0.481, There is a significant direct relationship at the level p&gt;0.01. But between emotional regulation and obsessive symptoms with r = -0.643, between emotional regulation and anxiety with r = -0.495, between emotional regulation and mental confusion with r = -0.611 there is an inverse significant relationship. Also, the results showed the role of two mediating variables of mental confusion and emotional regulation in the relationship between corona anxiety and obsessive symptoms. Conclusion: The model of the relationship between the anxiety caused by the transmission of the corona virus and the symptoms of obsessive-compulsive disorder according to the mediation of mental disorientation and emotion regulation has a good fit that with the increase in the number of emotions and defeat in regulating one's emotions, the symptoms of obsessive-compulsive disorder and confusion mental health also increases in the treatment staff. According to these findings, it is expected that health managers and medical centers will pay special attention to the psychological well-being of the personnel working in different parts of this profession.

Caregiver burden, attachment and cognitive emotion among the family caregivers of severe mental illness patients

BackgroundSerious mental illness (SMI) is a debilitating medical condition that causes stress and challenges for the family caregivers (FCs) of affected patients, increasing their caregiver burden (CB). This situation can activate attachment styles (AS) and trigger negative emotions, further contributing to CB. Given that AS and cognitive-emotional regulation (CER) can affect the CB of FCs of patients with SMI, the aim of this study was to evaluate the relationship between CB with AS, and CER among the FCs.MethodsThis cross-sectional descriptive-correlational study was carried out in May–November 2022. Participants were 278 FCs of patients with SMI consecutively recruited from Roozbeh leading psychiatric hospital, Tehran, Iran. Data were collected using a patients’ demographic and clinical characteristics questionnaire, an FCs’ demographic characteristics questionnaire, the Attachment Style Questionnaire, the Cognitive Emotion Regulation Questionnaire, and the Burden Scale for Family Caregivers, and were analyzed using the SPSS software (v. 16.0).ResultsCB had significant inverse relationship with secure AS (r = − 0.262) and significant positive relationship with fearful AS (r = 0.194) and dismissive AS (r = 0.242) (P < 0.01). Moreover, CB had significant inverse relationship with adaptive CER strategies and significant positive relationship with maladaptive CER strategies (P < 0.001). Regression analysis also showed that CB had significant relationship with secure AS and catastrophizing, rumination, self-blame, and positive refocusing CER strategies (P < 0.05).ConclusionThis study concludes that AS and CER can impact CB. There is a negative relationship between secure AS and CB, as well as between adaptive CER strategies and CB. Conversely, there is a positive relationship between avoidant AS and increased CB, as well as between maladaptive CER strategies and CB. It is recommended to adopt strategies that promote the use of secure AS and adaptive CER among the FCs of patients with SMI.

Prevalence and Risk Factors of Osteoporosis among Postmenopausal Women Visiting a District Hospital of Nepal: An Observational Study

Introduction: Osteoporosis and low bone mass affect millions of people worldwide, leading to severe consequences ranging from disability to mortality. This study aimed to determine the prevalence and risk factors of osteoporosis among postmenopausal women in a district of Nepal.Methods: An analytical cross-sectional study involving postmenopausal women from Nuwakot, Dhading, and Rasuwa districts in Nepal was conducted at Trishuli Hospital, Nuwakot. Ethical approval was taken from the Institutional Review Board of Nepal Health Research Council(Reference number: 1768). The prevalence of osteoporosis was determined, and the associated factors were analyzed using multivariate logistic regression. Dual-Energy X-ray Absorptiometry (GE-Lunar Prodigy) was used to measure Bone Mineral Density (g/cm2) at the proximal femur and lumbar spine. Various factors related to osteoporosis were also analyzed.Results: There were 384 postmenopausal women and the prevalence of osteoporosis was 82 (21.35%; 95% CI: 17.25%-25.45%)e. The mean age of female with osteoporosis was 67.52±8.84 years and that without osteoporosis was 55.70±7.69 years (p &lt;0.001). The multivariate logistic regression showed aOR 0.82 for body mass index.Conclusions: The study reports a lower prevalence of osteoporosis than expected in postmenopausal women. There was a significant inverse relationship between osteoporosis and body mass index. However, no significant association was observed between Bone Mineral Density, biochemical variables, smoking, and parity.

Correlation between lithium concentrations in drinking water and suicide attempt in the southeast of Iran.

Suicide, as an avoidable cause of death in public health systems, currently lacks effective global strategies to prevent it. However, several epidemiological studies found a correlation between the concentration of lithium (Li) in drinking water and lower suicide rates in the general population. Our ecologicalstudy investigated this hypothesis in the Rafsanjan districtof Iran. Samples from the public water supply in 16 areas in the district were analyzed using the graphite furnace atomic absorption. The resulting data were examined in relation to the suicide attempt from March 2019 to March 2020 obtained from Iran's Ministry of Health's registration system. During that period, 239 suicide attempts were recorded, resulting in an average of 69 individuals (85 women and 54 men) per 100,000 residents of the area. The average Li concentration in the drinking water was 47.30 µg/L (ranging from 9.4 to 141 µg/L). A negative significantcorrelation (r = -0.551, p = 0.027) between Li concentration in water and the rate of suicide attempt were observed in the studied population. Notably, these findings indicate an inverse significantrelationship between Li levels and suicide attempt rate in women (r = -0.725, p = 0.001). This is the first study in Iran that examines the relationship between Li levels in drinking water and suicide attempt rate. The findings of this study support an inverse relationship between the level of Li in public drinking water and the rate of womensuicide attempt.

The effect of sleep effectiveness on examination scores of first year osteopathic medical students

Medical students frequently encounter high levels of stress and pressure, which can negatively affect their mental health and sleep quality, a key determinant of cognitive function and academic success. This study assesses the relationship between sleep effectiveness and academic performance among medical students. An observational, cross-sectional survey took place at A.T. Still University - School of Osteopathic Medicine in Arizona (ATSU-SOMA), involving participants from the 2027 cohort. The Pittsburgh Sleep Quality Index (PSQI) questionnaire was used and exam scores from the second exam of the fourth block were analyzed. For the purpose of our inquiry, the “Sleep Effectiveness” component score of the PSQI was used for our analysis. The results indicated a significant inverse relationship between sleep effectiveness and exam performance (R² = 0.087, p =0.000262), demonstrating that increased sleep effectiveness was associated with lower exam performance. The study highlights the sheer amounts of confounding variables in the preconceived notion that “,Sleep is the key for academic success.” This research suggests that academic performance is best explained by multiple variables rather than simply one. Future studies should investigate the long-term effects of sleep deprivation and explore interventions beyond sleep hygiene, including stress and time management strategies. Understanding the broader impact of sleep on medical education is essential for fostering better outcomes for students in both academic and clinical settings.

Does Prevalence of Female Sexual Dysfunction Differ among Infertile Patients with or without Polycystic Ovary Syndrome: A Cross-Sectional Study.

While the effects of polycystic ovary syndrome (PCOS) and infertility on women's health have often been discussed, not many studies have assessed the other complications of infertility. One of these complications is female sexual dysfunction (FSD), a range of psychosexual disorders. The aim of this study is to investigate the prevalence of FSD in PCOS and its comparison with other causes of infertility. In this cross-sectional study, two questionnaires were filled out by two groups (60 people each) of infertile patients, due to PCOS and other causes, referred to Arash Women's Hospital from December 2018 to 2019. The data was analyzed in SPSS software to evaluate the frequency of FSD in the whole study population and each group separately as well as its relationship with age, history of pregnancy, the literacy level of the patient or spouse, body mass index (BMI), infertility duration, hirsutism, and acne. The frequency of FSD in the study group had a significant inverse relationship with the women's level of education (P=0.044), although no such correlation was found with age, pregnancy history, spouse's literacy level, BMI, duration of infertility, acne, and hirsutism. In the comparison group, there was a significant relationship between the duration of infertility and FSD (P=0.002). The prevalence of FSD in the study and comparison groups was 43.1 and 52%, respectively. The prevalence of FSD sub-domains in all categories, except for pain, was higher in the study group. PCOS, compared to other groups, presented at a relatively younger age. In the PCOS group, patients with lower education levels were more likely to suffer from FSD. This suggests the effect of education and awareness on the sexual performance of these people. No significant difference in FSD experience was found between PCOS and other groups.
