ABSTRACT

BACKGROUND: The effects of visceral fat and body fat on osteoporosis (OP) have long been controversial. This study investigated the correlation between visceral fat and bone mineral density (BMD) in perimenopausal women aged 40-60. The goal was to evaluate the current state of BMD and its influencing factors, with the specific objective of establishing a foundation for preventing and treating osteoporosis in this demographic.

METHODS: This case-control study included female participants (n = 330), aged 40-60 years, from the Health Management Center of Guilin Medical College Affiliated Hospital, China, between January 2020 to August 2023. Their BMD was assessed using an ultrasound bone mineral density meter, and the visceral fat area was determined utilizing a body composition analyzer. Furthermore, past medical history, dietary habits, and lifestyle factors were collected through a telephonic questionnaire survey. Additionally, we analyzed the baseline characteristics of the population, bone status and visceral fat status, and the relationship between these variables.

RESULTS: Among perimenopausal women with varying bone mineral density statuses, there was no significant difference regarding body fat percentage (p = 0.359). In contrast, a statistically significant difference was observed regarding visceral fat area (p < 0.001) and vitamin D (p < 0.001). The visceral fat area exhibited an inverse correlation with bone density (r = -0.313, p < 0.001). Additionally, mediation analysis outcomes did not support the hypothesis that visceral fat affects bone density through its influence on vitamin D levels (p = 0.92).

CONCLUSIONS: Among perimenopausal women, visceral fat is negatively associated with bone density, suggesting that the distribution of body fat rather than the total amount plays a pivotal role in the development of osteoporosis. These findings suggest the significance of regular physical exercise and the abdominal fat distribution for perimenopausal women.

ABSTRACT

BACKGROUND: During the COVID-19 pandemic, disease coding significantly influenced national and international strategies for prevention, treatment, and control. This study aimed to assess the factors influencing COVID-19 records’ coding errors in teaching hospitals in South Khorasan province.

MATERIALS AND METHODS: In 2022, researchers conducted a cross-sectional study in South Khorasan Province, Iran. Data was gathered using a self-developed questionnaire distributed among medical coders in all hospitals. Descriptive statistics were employed in the data analysis using SPSS version 19.

RESULTS: The study’s results showed that non-observance of diagnostic principles by physicians (66 out of 92), a lack of specialized medical coding specialists (52 out of 92), and the use of ambiguous and non-standard abbreviations (51 out of 92) were the most significant factors affecting COVID-19 coding errors. Among the three main factors affecting COVID-19 records’ coding errors, factors related to the medical coder (47.66 out of 92), factors related to healthcare providers (29.8 out of 92), and organizational and environmental factors (21.4 out of 92) were the most significant.

CONCLUSION: This study revealed that multiple factors contribute to coding errors in COVID-19 records, with the most critical being physicians’ non-adherence to diagnostic principles, the shortage of medical coding specialists, the use of unclear and non-standard abbreviations, and the absence of COVID-19 coding continuing education. Therefore, we recommend conducting workshops on diagnosis and coding for medical coders, particularly emphasizing the precise coding of COVID-19 records.

ABSTRACT

BACKGROUND: Medication errors can lead to damage to patients with various disabilities or death. This study aims to identify factors affecting the incidence of medication error and its association with patient safety culture from the nurse’s perspective during the COVID-19 pandemic.

MATERIALS AND METHODS: This cross-sectional study was conducted among 340 employed in the hospitals affiliated with Shiraz University of Medical Sciences in 2021. Data were collected by applying a questionnaire for medication error and the standard questionnaire of the Hospital Survey on Patient Safety Culture. Descriptive statistics, the independent t-test, ANOVA, and Pearson correlation were applied using SPSS software version 23.

RESULTS: The main reasons for medication errors were fatigue due to the workload (3.13±1.16 out of 5), method of supervision in the hospital units (3.06±0.98 out of 5), and massive pile-up of duties (3.00±1.19 out of 5). Other results indicated a significant negative association between factors affecting medication error and patient safety culture (r=-0.574, p=0.002). A significant correlation was observed among factors affecting medication error and patient safety culture with demographic determinants of age and years of working experience (p<0.05). Significant differences were also observed among the two main studied variables, the number of monthly work shifts, and the number of patients (p<0.05).

CONCLUSION: Applying strategies for the reduction of physical fatigue and mental exhaustion along with balancing work shifts and managing the accumulative duties and massive tasks can help decrease the rates of medication errors.

ABSTRACT

BACKGROUND: Forecasting the longevity of patients’ immune stability could be the most effective approach to preventing illnesses. This study investigates immunoglobulin M (IgM) serum longevity, immunoglobulin G (IgG), and corresponding risk factors in the first phase seropositive patients in Mazandaran, Iran.

MATERIALS AND METHODS: This descriptive cross-sectional study aimed to assess IgM and IgG serum levels in a cohort of 184 seropositive patients during six months. The data analysis involved various statistical methods including descriptive statistics, the chi-square test, independent and paired t-tests, and single and multivariate logistic regression.

RESULTS: A total of 103 (56%) patients lacked the necessary antibodies, whereas 81 (44%) remained seropositive. According to the results of multivariable logistic regression, patients with a travel history, hospital admissions, and end-stage renal disease (ESRD) had 3.24 (P=0.04), 12.63 (P=0.018), and 9.79 (P=0.001) times higher chances of stable seropositivity, respectively. The average IgG and IgM serum levels fell by 4.5 and 3 units, respectively (P<0.001). In addition, serum levels of IgM and IgG increased by 12% and 12.5%, respectively, and dropped by 75.5% in both serums. There was no increase in either serum level for any of the patients.

CONCLUSION: The duration of immune serum stability in patients can significantly reduce disease mortality. The concurrent detection of IgM and IgG antibodies also assists in identifying the infectious stage.

ABSTRACT

BACKGROUND: The progression of high-grade cervical intraepithelial neoplasia (CIN) and cervical cancer is accompanied by a reduction in the immune response. The objectives of the study were to determine whether colposcopic lesion area is associated with serum levels of cytokines IL (interleukin) -1, IL-6, IL-8, IL-10, IL-12 and TNF-α in precursor lesions of cervical cancer.

METHODS: The study population comprised patients with high-grade squamous intraepithelial lesion who had undergone colposcopy, cervical biopsy, and measurements of serum cytokines by ELISA (Enzyme-Linked Immunosorbent Assay). Genotyping for HPV (human papillomavirus) 16, 18, 45 and 52 was performed by PCR (Polymerase Chain Reaction). ROC (Receiver Operating Characteristic) curves were calculated to determine whether there existed a cut-off value for serum cytokines in patients with colposcopic lesion area smaller vs larger than 1 cm². For cytokines with significant results, these cut-off values were used to perform the multivariable analysis.

RESULTS: There were 71 patients with CIN 2/3. ROC curves were calculated to verify a cut-off value for serum cytokine levels that could be used to distinguish between lesion areas <1 cm2 vs ≥1 cm2. Values with statistical significance were IL-1 >13.3 pg/mL and IL-12 ≤349.6 pg/mL. In the multivariable analysis, the independent variables associated with colposcopic lesion area greater than 1cm² were IL-1>13.3 pg/mL and IL-12 ≤349.6 pg/mL [OR (95% CI) = 10.10 (1.50-67.96); OR (95% CI)=10.70 (1.17-97.45), respectively].

CONCLUSION: Although CIN 2/3 is a local uterine cervix lesion, there is a systemic immunological response. Our results are unprecedented and could be the target of new important studies in public health and cervical cancer prevention.

ABSTRACT

BACKGROUND/OBJECTIVES: Metabolic syndrome (MetS) is closely connected to dietary and lifestyle factors, with diet being one of the primary risk factors for MetS, acting as a key factor in both prevention and management. In this study, we analyzed the mediating effect of the Korean Healthy Eating Index (KHEI) on the relationship between lifestyle patterns and MetS in middle-aged Koreans using data from the 2019-2021 Korea National Health and Nutrition Examination Survey (KNHANES).

SUBJECTS/METHODS: This study examined data from 5,196 adults aged 40-64 yrs who participated in the eighth KNHANES. Data on 5 lifestyle factors-smoking, alcohol consumption, physical activity, sleep duration, and stress perception-were analyzed. The latent class analysis (LCA) was performed using Mplus 8.11, and SPSS PROCESS Macro v4.2 was used for statistical analysis to analyze the mediating effect of the KHEI.

RESULTS: The model categorized lifestyle factors into three into 3 clusters: ‘Low Activity Class,’ ‘Low Activity and Smoking Class,’ and ‘Multiple Risk Class.’ The KHEI mediation analysis showed significant effects: 0.0205 (95% confidence interval [CI], 0.0062-0.0363) in the ‘Low Activity and Smoke Class,’ and 0.0420 (95% CI, 0.0133-0.0726) in the ‘Multiple Risk Class.’ The mediating effect of the KHEI domain “adequacy” was significant in these groups, with effects of 0.0357 (95% CI, 0.0184-00563) and 0.0662 (95% CI, 0.0364-0.6491), for the respective groups. Balance of energy intake was significant in the group with ‘Multiple Risk Class’ (0.0189; 95% CI, 0.0044-0.0378).

CONCLUSION: The results suggest that a healthy diet improves health management and reduces risk factors for MetS. Nonetheless, better strategies for dietary improvement through a detailed analysis of KHEI components are warranted.

ABSTRACT

BACKGROUND/OBJECTIVES: The prevalence of depression has increased globally, and depressive symptoms have been reported to lead to undesirable lifestyle choices, including poor eating behaviors. The aim of this study was to assess the severity of depressive symptoms in young adults and to investigate the differences in eating habits and dietary quality by the degree of these symptoms.

SUBJECTS/METHODS: This cross-sectional study included 497 young adults aged 19-39 yrs living in Chungcheong, Korea. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression (CES-D) scale, and eating habits and dietary quality were surveyed using questionnaires and nutrition quotient (NQ) for Korean adults.

RESULTS: The prevalence of depression in the participants was approximately 31.4%, based on a depressive symptom score of 16 on the CES-D scale, and the proportion of women was significantly higher than men. The depressed group considered food combinations and consumed snacks more frequently than the nondepressed group. No statistically significant differences were found in the total NQ score between the depressed and nondepressed groups; however, the moderation score was significantly lower in the depressed group for all participants and female participants.

CONCLUSION: We found that dietary quality, including snacking and moderation-related eating habits, varied with the degree of depressive symptoms in young adults. Further intervention studies are needed to clarify the association between dietary factors and depressive symptom.

ABSTRACT

BACKGROUND: Menopause brings about significant hormonal changes that can affect various aspects of women’s health, including nasal function. However, the specific impact of menopause on nasal health in Indian women remains underexplored. This study aims to compare nasal function using the Nasal Obstruction Symptom Evaluation (NOSE) score between premenopausal and postmenopausal Indian women.

MATERIALS AND METHODS: A comparative cross-sectional study was conducted involving 107 premenopausal and 111 postmenopausal women recruited from a tertiary care hospital in India. Demographic data, medical history, and NOSE scores were collected. Statistical analyses including Wilcoxon rank-sum test, Chi-squared test, logistic regression, and receiver operating characteristic curve analysis were performed.

RESULTS: Postmenopausal women were significantly older with higher body mass index (BMI) compared to premenopausal women. Postmenopausal women consistently had higher NOSE scores indicating worse nasal function across various time points. Logistic regression revealed menopausal status as a significant predictor of severe nasal obstruction (odds ratio: 1.45, 95% confidence interval: 1.10-1.90, P = 0.015), independent of age, BMI, and other factors.

CONCLUSION: Menopause is associated with a significant decline in nasal function in Indian women, as evidenced by higher NOSE scores in postmenopausal women. Addressing nasal symptoms in postmenopausal women may improve their quality of life. Further research is needed to develop targeted interventions for managing nasal obstruction in this population.

ABSTRACT

BACKGROUND: The hormonal shifts and physiological changes during menopause, including perimenopause and postmenopause, significantly affect women’s mental health, often causing depression and sleep disruptions. The objectives of this study are to estimate the prevalence of depression and sleep disturbances among perimenopausal and postmenopausal women and to find the associated risk factors.

MATERIALS AND METHODS: In a community setting, 462 women aged 45-60 years were chosen from 23 clusters using probability proportional to size sampling. Sociodemographic information was collected through standardized surveys, whereas depression levels were measured with Beck’s Depression Inventory-II and sleep quality with the Pittsburgh Sleep Quality Index. Statistical analysis was done using SPSS version 21.

RESULTS: The prevalence of depression among the study participants was 33.3% (95% confidence interval [CI]: 29%, 37%), whereas poor sleep quality was found in 37% (95% CI: 36%, 39%). Factors such as low socioeconomic status (adjusted odds ratios [aOR] =1.64), recent negative life events (aOR =2.27), lack of social media usage (aOR =2.77), and being unmarried/widowed (aOR =2.1) were identified as independent predictors of depression. Living in urban areas (aOR =1.69), low socioeconomic status (aOR =1.96), and inadequate intake of fruits and vegetables (aOR =0.43) were identified as independent predictors for sleep disturbances.

CONCLUSIONS: This study highlights a notable burden of depression and sleep disruptions among menopausal women. Tackling these challenges necessitates accessible mental healthcare, educational workshops on stress management and sleep habits, nutritional guidance, and peer support networks. Incorporating these measures into health initiatives and policies holds promise for mitigating these concerns and enhancing overall well-being.

ABSTRACT

INTRODUCTION: Postmenopausal status is a known risk factors for developing metabolic syndrome (MetS). Studies focusing on establishing the relationship between Mets and mental health state are limited.

AIMS AND OBJECTIVE: To identify the frequency of MetS along with its components in geriatric females and assess its relationship with three negative emotional states (depression/anxiety/stress).

MATERIALS AND METHODS: Women aged ≥60 years from October 2020 to March 2022 were included in study. We used the Consensus Definition IDF and AHA/NHLBI (2009) criteria to classify subjects as having metabolic syndrome. Mental health status were assessed using Depression Anxiety and Stress Scale (DASS 21) questionnaire.

RESULTS: The frequency of metabolic syndrome in this sample was 36.58% (30 out of 82 patients). The Depression, anxiety, stress scale and total scores in women with MetS were 14 ± 5.3, 8.5 ± 3.92, 12.13 ± 5.58 and 34.66 ± 9.60 as compared to 6.6 ± 3.7, 5.3 ± 2.49, 7.1 ± 3.12 and 19.2 ± 6.51 in those without MetS; difference being statistically significant.

CONCLUSION: MetS results in poor mental health state in geriatric women but large-scale studies are needed to clarify this association.
