Association of Neutrophil-Percentage-To-Albumin Ratio(NPAR) with depression symptoms in U.S. adults: a NHANES study from 2011 to 2018

BackgroundInflammation is crucial in the development of depression. This study aims to examine the potential association between the Neutrophil-Percentage-to-Albumin Ratio(NPAR) and depression symptoms.MethodsThis study adopted a cross-sectional design, involving patients with depression symptoms and those without depression symptoms with comprehensive NPAR data originated from the National Health and Nutrition Examination Survey(NHANES) spanning 2011 to 2018. The research utilized weighted multivariate logistic regression models and multivariate linear regression to investigate the linear relationship between NPAR levels and depression symptoms and its severity scores. The characterization of nonlinear relationships was accomplished by employing fitted smoothing curves. Furthermore, subgroup analyses and interaction assessments were conducted to offer additional insights.ResultsThis study involved a total of 10,829 participants, and the prevalence of depression among them was found to be 15.08%. The multiple logistic regression analysis revealed a statistically significant positive association between the continuum of NPAR and depression symptoms[OR:1.03, 95% CI: (1.00, 1.05)], as well as depression severity scores[β: 0.08, 95% CI: (0.04,0.11)]. Stratifying NPAR into quartiles, we found that higher NPAR associated with increased odds of depression symptoms. Furthermore, in subgroup analysis, there were no significant differences in the relationship between NPAR levels and depression symptoms or its severity scores within populations with or without diabetes and cardiovascular diseases. Additionally, the use of a two-stage linear regression model uncovered a non-linear relationship between NPAR and depression symptoms.ConclusionsOur research indicates that NPAR levels were associated with depression symptoms. To corroborate our findings, larger prospective studies are warranted to elucidate nonlinear associations in greater detail.

Postpartum hair loss is associated with anxiety.

This study examined the relationship between postpartum hair loss and psychological symptoms. This questionnaire-based, cross-sectional study included postpartum women who had delivered at two facilities and completed the questionnaire 10-18 months after delivery. Study protocols were sent by mail in two parts. Baseline characteristics and information regarding the pregnancy, delivery, childcare, and postpartum hair loss were obtained via a questionnaire. Psychological symptoms were assessed via the Whooley Questions, Generalized Anxiety Disorder 2-item, and Edinburgh Postnatal Depression Scale. Participants were divided into two groups based on psychological symptoms. Multivariate analyses were performed. In total, 331 responses were analyzed. Women with very much hair loss felt significantly more anxious than those with no postpartum hair loss, as reported on the Generalized Anxiety Disorder 2-item anxiety subscale (odds ratio: 4.47). Multiple logistic regression analysis revealed that primiparity, greater amount of postpartum hair loss, and higher Athens Insomnia Scale scores were predictors of Generalized Anxiety Disorder 2-item anxiety. Adjusted odds ratio of having anxiety among those with very much postpartum hair loss was 4.58 (95% confidence interval, 1.18-17.74) compared to those with no postpartum hair loss. A greater amount of postpartum hair loss was independently associated with postpartum anxiety on the Generalized Anxiety Disorder 2-item.

. Predictive Value of Pre-delivery Serum β-human Chorionic Gonadotropin, Fibrinogen, and Homocysteine for Hypertensive Disorders of Pregnancy

Introduction: it was to investigate the relationship between pre-delivery serumβ-human chorionic gonadotropin (β-HCG), fibrinogen (FIB), and homocysteine (HCY) with hypertensive disorder complicating pregnancy (HDCP). Materials and Methods: 200 HDCP patients and 150 normal pregnant women were selected as study subjects. Fasting cubital venous blood samples were collected to measure serum triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL), and low-density lipoprotein (LDL), as well as β-HCG, FIB, and HCY levels. Pearson correlation analysis examined relationship between β-HCG, FIB, HCY, and HDCP. Receiver operating characteristic (ROC) curve analysis evaluated the predictive value of these indicators for HDCP. Multiple logistic regression analysis identified risk factors (RFs) for HDCP.Results: serum TG, TC, HDL, LDL, FIB,β-HCG, and HCY were greatly elevated in the HDCP group versus control group (CG) (P<0.05). Serumβ-HCG, FIB, and HCY showed notable positive correlations with HDCP (r = 0.935, 0.547, 0.811; P<0.05), and the areas under the ROC curve (AUC) for predicting HDCP based on serum β-HCG, FIB, HCY, and their combination were 0.743, 0.659, 0.801, and 0.886, respectively (P<0.05). Lipid indicators and serum levels of FIB, β-HCG, and HCY were RFs for HDCP.Conclusion:pregnant women with HDCP exhibited markedly elevated serum lipid levels and FIB, β-HCG, and HCY levels before delivery, which can serve as predictive indicators for HDCP.

Socio-behavioural associates of Early Childhood Caries among preschool children aged three to four years in Gampaha district, Sri Lanka: a cross sectional study

BackgroundEarly Childhood Caries (ECC) is a highly prevalent disease among preschoolers in Sri Lanka, with stagnated prevalence over the decades. Therefore, it is important to determine the socio-behavioural associations of ECC among preschoolers to reduce the country’s ECC burden.MethodsA cross-sectional study with a multistage cluster sampling technique was used to select 3 to 4 year-old preschoolers/mothers dyads in Gampaha district in 2019. Preschoolers who completed third birthday and had not completed fifth birthday on the day of data collection were selected. The dependent variable was the presence (dmft ≥ 1) or absence (dmft = 0) of ECC. Independent variables were sex, monthly family income, mother’s educational and occupational status, child’s birth order, family type, frequency of consumption of sweets and sweetened drinks, time of sweet consumption during the last 24 h, toothbrushing frequency, supervision of toothbrushing, dental visit, and maternal dental caries. A pre-tested validated questionnaire was used. Multiple logistic regression analysis was used.ResultsTotal of 1038 preschoolers were selected. There were 529 females (51.0%) and 509 males (49.0%). The prevalence of ECC was 56.3% (95% CI: 53.1–59.3). Consuming sweets between meals had a higher odds ratio than consuming sweets after main meals (OR = 1.72, 95% CI:1.25–2.35), consumption of sweets every day had a higher odds ratio than consumption of sweets several times a week or less (OR = 2.89, 95% CI: 2.02–4.13), consumption of sweetened drinks every day had a higher odds ratio than consumption of sweetened drinks several times a week or less (OR = 1.73, 95% CI: 1.07–2.79), and the presence of maternal caries had a higher odds ratio than the absence of maternal caries (OR = 1.74, 95% CI: 1.12–2.69). The use of adult fluoridated toothpaste than not using adult fluoridated toothpaste (OR = 0.64, 95% CI:0.48–0.85), tooth brushing twice per day than not brushing twice per day (OR = 0.67, 95% CI:0.51–0.89), and supervised toothbrushing than unsupervised toothbrushing (OR = 0.61, 95% CI: 0.41–0.93) was negatively associated with ECC.ConclusionsECC is highly associated with sweet consumption and oral hygiene behaviours among preschoolers in Gampaha District. Interventions should focus on the oral health behaviours of preschoolers to reduce ECC burden.

Clarifying the importance and moderating roles of temporal self-regulation theory across behaviour types

Objectives The aim of this study was to explore the utility of temporal self-regulation theory across four behaviours differing in complexity and approach or avoidance nature. Specifically, we explored if intention, habit, cues, self-regulation (disorganisation, coping planning, task switching, present orientation, sensation seeking, automaticity, planning and distractibility) and interactions between constructs could account for variance in fruit consumption, unhealthy snacking, walking and recycling. Methods and Measures Two hundred and fifty-four participants completed a two-part online survey measuring theory constructs at time one and behaviours at time two. Data was analysed using hierarchical multiple regression and binary logistic regression analyses. Results Findings partially support the theory with differential importance of constructs across behaviours. Intention, habit, sensation seeking and automaticity significantly predicted fruit consumption. Intention and cues significantly predicted unhealthy snacking. There were no significant predictors of walking. Habit, present orientation, sensation seeking, and interactions between intention and sensation seeking, and intention and planning significantly predicted recycling. Conclusion Findings may help develop future frameworks to guide research and tailored interventions using the theory according to behaviour type. Behavioural pathways suggested in the theory may be reconsidered, or other constructs could be included as extensions of the model to improve the theory’s utility.

Association between inflammation indicators (MLR, NLR, SII, SIRI, and AISI) and erectile dysfunction in US adults: NHANES 2001–2004

BackgroundThis study aimed to assess the relationship between multiple indicators of inflammation and erectile dysfunction through an analysis of data from the National Health and Nutrition Examination Survey (NHANES). This represents the first large-scale, cross-sectional investigation that explores this association by jointly analyzing various inflammatory markers.MethodsWe performed a cross-sectional analysis with NHANES data from 2001 to 2004. Erectile dysfunction (ED) was evaluated through a self-reported questionnaire and testosterone levels, while inflammatory markers were derived from standard blood test parameters. Our approach included multivariate logistic regression, subgroup analyses, generalized additive modeling (GAM), and smoothed curve fitting to evaluate the link between inflammatory markers (NLR, MLR, SII, SIRI, AISI) and ED. Additionally, we utilized receiver operating characteristic (ROC) curves to determine the diagnostic utility of these markers, comparing their area under the curve (AUC) values.ResultsA total of 3610 participants were included in this study, and the population-weighted ED patients were 18.91%. In the adjusted model, multiple logistic regression analysis showed a positive association between five inflammatory indicators (Ln-NLR, Ln-MLR, Ln-SII, Ln-SIRI, and Ln-AISI) and ED. Smoothed curve fitting showed a nonlinear positive correlation between the five inflammatory indicators and ED. Furthermore, subgroup analyses showed that this correlation was stronger in people older than 50 year. ROC curve analysis showed the highest diagnostic performance for the study outcome with MLR (AUC = 0.616, 95% CI: 0.5952–0.637), which was significantly better than SIRI, NLR, AISI, and SII.ConclusionMLR is potentially more effective than other biomarkers (NLR, SIRI, AISI, SII) in predicting ED. Men with elevated MLR levels should be particularly aware of their increased risk of developing ED.

Factors associated with neurological outcomes in patients experiencing out-of-hospital cardiac arrest and severe acidaemia: retrospective analysis of a nation-wide registry

Background and objectiveAcidaemia is common among individuals who experience out-of-hospital cardiac arrest (OHCA). While severe acidaemia is a strong predictor of unfavourable outcomes, a subset of patients exhibits dramatic recovery. Despite these conflicting outcomes, little is known about the factors associated with neurological outcomes in those who experience OHCA with severe acidaemia. MethodsThis retrospective analysis used data from a Japanese multicentre nationwide database, the Japanese Association for Acute Medicine OHCA Registry. The analysis included data from adult patients with OHCA for whom blood pH data were available upon arrival to hospital. The primary outcome was 30-day survival with favourable neurological outcomes, defined as a Glasgow-Pittsburgh cerebral performance category score of 1 or 2. Patients were categorised with severe acidaemia if their blood pH was ≤ 6.8. Factors associated with favourable outcomes were investigated using multiple logistic regression analysis. ResultsData from 49,044 patients were included in the analysis, of whom 16,620 exhibited severe acidaemia with a median pH of 6.70 (interquartile range [IQR] 6.61–6.76], and 0.5% (86/16,620) experienced a neurologically favourable outcome. After adjustment for important prognostic factors, witnessed status exhibited a strong association with favourable neurological outcome (adjusted odds ratio [aOR] 6.46 [95% confidence interval (CI) 2.64–15.8]), while initial blood pH exhibited no significant association (aOR 0.90 with every 0.1 unit increase [95% CI 0.71–1.14]). ConclusionAlthough the number is small, a notable number of patients with severe acidaemia exhibited good neurological recovery. Witness status was critical for the prognosis of these patients.

Family planning knowledge, use, and associated factors among women with mental illness and epilepsy in Rwanda: a cross-sectional study.

Family planning knowledge and access to quality family planning services occupy a central position in the lives of all women of reproductive age. However, women with mental illness and epilepsy who are at a high risk of sexual violence, unwanted pregnancies, poor obstetric outcomes, and drug interaction consequences, need it the most. Understanding their family planning knowledge and utilization remains crucial for meeting their needs. The present study aims to assess knowledge, use of family planning, and associated factors among women living with mental illness and epilepsy who attend the Ndera Neuropsychiatric Hospital and affiliated branches. A cross-sectional study was conducted between October 2022 and February 2023. The study involved a purposive sample of 289 women who attended the Ndera Neuropsychiatric Hospital and its two affiliated branches during the data collection period. Psychiatric nurses administered a structured questionnaire. Data were analyzed using descriptive statistics, and multiple logistic regression analysis was performed to assess the factors associated with the use of family planning methods. Out of 289 who participated in the study, the majority (96.9%) were aware of family planning methods, most (67.8%) had used one method once in their life course, a half (51.9%) were using a family planning method at the time of data collection, and a slight number (26%) expressed intentions of using a family planning method in the future. The most known and used methods were respectively the injectable (17.5%) and oral contraceptive pill (17.5%). Regarding the natural family planning methods, breastfeeding and withdrawal were less used. Being single (AOR = 66.4, 95% CI: 9.8, 44) or married (AOR = 51.4, 95% CI: 11.9-22), having a primary level of education (AOR = 5.6, 95% CI: 2.0, 15.9), knowing a contraceptive method (AOR = 5.8, 95% CI: 0.6, 49) and suffering from brief psychotic disorders (AOR = 2.7, 95% CI: 1.1, 6.6) predicted a higher utilization of family planning. Most of the women with mental illness in this study were aware of family planning methods and had used one of the family planning methods in life. The national average is below when it comes to family planning awareness. It is important to improve family planning education and counseling for women who attend psychiatric outpatient clinics.

Factors Associated with Maternal Morbidity in Patients with Eclampsia in Three Obstetric Intensive Care Units: A Retrospective Study.

(1) Introduction. Eclampsia is a rare complication that can occur during pregnancy and has a significant impact on maternal and neonatal outcomes. The aim of this study was to investigate the risk factors associated with significant maternal morbidity after an eclamptic seizure. (2) Methods. An observational retrospective study was performed in three maternity hospitals in Romania between 2015 and 2023 and included pregnant patients diagnosed with eclampsia. Clinical and paraclinical data were investigated, and the impact of several risk factors was assessed using multiple logistic regression analysis. The results were reported as risk ratios (RRs) and 95% confidence intervals (Cis). (3) Results. A total of 104 patients with preeclampsia, of whom 23 experienced eclamptic seizures, were included in this study. A total of 82.6% of the patients diagnosed with eclampsia experienced a form of significant morbidity (stroke, PRES syndrome, or any organ failure/dysfunction). Our regression analysis revealed that advanced maternal age (RR: 12.24 95% CI: 4.29-36.61, p = 0.002), the presence of thrombotic disorders (RR: 9.17, 95% CI: 3.41-23.70, p = 0.03), obesity (RR: 4.89, 95% CI: 0.78-18.15, p = 0.036), and smoking status (RR: 2.18, 95% CI: 0.13- 6.51, p = 0.042) significantly increase the risk of maternal comorbidities. (4) Conclusions. Careful monitoring of pregnant patients, adequate weight control during pregnancy, and correct anticoagulation of individual patients could reduce the extent of postpartum comorbidities that can result from an eclamptic seizure.

Relationship between perception of body image on obesity and smoking status by age group in women: Findings of a seven-year Korean National Survey.

This descriptive study examined the relationship between body image perception and smoking status among women aged 19-64 years in Korea, using data from the Korea National Health and Nutrition Examination Survey (KNHANES). This study is a secondary analysis of data gathered from the KNHANES between 2014 and 2020, encompassing 12515 women aged 19-64 years. The final study group consisted of 742 current smokers (CS), 132 hidden smokers (HS), and 11641 non-smokers (NS). Hidden smokers were defined as participants who reported being non-smokers but had urine cotinine levels >50 ng/mL. The participants were divided into three age categories: 19-29, 30-49, and 50-64 years. A multiple logistic regression analysis was used to assess the relationship between body image perception and smoking status, by age group. Baseline statistics indicated that smokers (both CS and HS) generally had a lower socioeconomic status across all age groups. The highest rate of obesity perception was observed in the CS group, followed by the HS group, in both groups of women aged 19-29 and 30-49 years. However, only women aged 19-29 years in the CS group were more likely to perceive themselves as obese than those in the NS group (AOR=2.60; 95% CI: 1.49-4.52; p=0.001). Furthermore, factors such as current smoking status (AOR=2.32; 95% CI: 1.28-4.23; p=0.006), higher body mass index (AOR=2.95; 95% CI: 2.59-3.37; p<0.001), and perceived health status as poor (AOR=3.82; 95% CI: 2.11-6.92; p<0.001), significantly influenced the perception of obesity in this age group. This study identified a notable relationship between obesity perception and smoking among women aged 19-29 years only. These findings suggest that interventions aimed at weight reduction or modifying the perception of obesity, could potentially aid smoking cessation efforts in young women.

Prevalence of misophonia and its association with depression and obsessive-compulsive disorder among medical students.

Misophonia, a neurobehavioral syndrome, reduces tolerance to specific stimuli and impacts various domains of life. It is also strongly correlated with obsessive-compulsive disorder (OCD) and depression. This study aimed to investigate the prevalence of misophonia among medical students at King Saud University (KSU), Saudi Arabia, identify related sociodemographic factors, and assess misophonia association with OCD and depression. This cross-sectional study included 371 participants. The study tool was distributed electronically between November 19 and December 07, 2023. It consisted of 4 sections: a questionnaire developed by the research team, the Amsterdam Misophonia Scale (A-MISO-S), the Obsessive-Compulsive Inventory-Revised (OCI-R), and the Patient Health Questionnaire-9 (PHQ-9). The results indicated that 42.32% of the participants had previously experienced misophonia, with symptoms developing suddenly in 28.66%. The majority of participants had subclinical misophonia (71.16%) and minimal depression (37.47%), with a significant proportion experiencing mild-to-severe misophonia (28.84%) and varying degrees of depression (33.15%). Approximately 31.00% of the students exhibited likely OCD. The PHQ-9 and A-MISO-S scores showed weak positive correlations, whereas the OCI-R and A-MISO-S scores showed a moderate positive correlation. Furthermore, a moderate positive correlation was observed between the OCI-R and PHQ-9 scores. Multiple logistic regression analysis revealed that sex, family history of misophonia, depression severity, and OCD were significantly associated with clinical misophonia. This study underscores the significance of recognizing misophonia among medical students and its associated factors, such as OCD and depression. Further multicenter studies using more rigorous research methodologies are warranted.

Incidence and Progression of Diabetic Retinopathy in Urban India: Sankara Nethralaya Diabetic Retinopathy Epidemiology and Molecular Genetics Study, 15yr Follow up

ABSTRACT Purpose: To evaluate the 15 year incidence and progression of Diabetic Retinopathy (DR) and identify risk factors among Indian population. Methods: From a cross-sectional study of 1425 subjects, 911 participants took part in the 4-year follow-up. Out of these 911 participants, 140 returned for the 15-year follow-up, with baseline examinations conducted between 2003 and 2006, and subsequent follow-ups occurring from 2007 to 2011 and the current 15-year follow-up from 2018 to 2021. Of the 140 participants, 112 were eligible for analysis after excluding individuals with ungradable fundus photographs. Results: The 15-year incidence of any diabetic retinopathy (DR) was 5%, with mild NPDR and moderate NPDR at 1.57% and 2.7%, respectively. Proliferative DR was observed in 0.71% of cases, while diabetic macular edema (DME) and sight-threatening diabetic retinopathy (STDR) rates were 0.48% and 1.10%, respectively. Age-standardized rates revealed a significant association with increasing age and incident any DR and STDR. DR progression over 15 years included 7.5% one-step and 1.75% two-step progressions, while regression was limited to 1.75% one-step regression. Multiple logistic regression analyses revealed that baseline duration of diabetes, systolic blood pressure, HbA1c levels, and the presence of anemia influenced the incidence of any DR, DME, and STDR. Smoking and higher HbA1c were identified as risk factors for one-step progression of DR. Conclusion: This study provides crucial insights into the long-term incidence, progression, and regression of DR among individuals with Type 2 diabetes in India.

Investigation of factors influencing abnormal pulmonary ventilation function in occupational exposed populations and the establishment of a risk prediction model

The purpose of this study is to investigate the influencing factors of abnormal pulmonary ventilation function in occupational exposed populations and to establish a risk prediction model. The findings will provide a basis for formulating corresponding strategies for the prevention and treatment of occupational diseases. The study focused on workers who underwent occupational health examinations in the year 2020. Statistical analysis was conducted using methods such as t-tests, chi-square tests, and multiple logistic regression analysis. Additionally, machine learning methods were employed to establish multiple models to address classification problems. Among the 7472 workers who participated in the occupational health examination, 1681 cases of abnormal pulmonary ventilation function were detected, resulting in a detection rate of 22.6%. Based on the analysis of occupational hazard data, a risk prediction model was established. Age, work tenure, type of the employing enterprise, and type of dust exposure are all identified as driving factors for abnormal pulmonary function. These factors were used as predictive variables for establishing the risk prediction model. Among the various models evaluated, the logistic regression model was found to be the optimal model for predicting abnormal pulmonary ventilation function.

International dietary quality index and its association with diabetes in RaNCD cohort study

Diabetes and its complications pose a significant threat to global health. Various factors contribute to the development of diabetes, with diet being an important trigger. The Dietary Quality Index-International (DQI-I) serves as an indicator of changes in diet and its association with chronic diseases, including diabetes. The aim of this study is to examine the association between DQI-I and diabetes in adults. Data from the first phase of the Ravansar Non-Communicable Disease Cohort Study (RaNCD) were used for this cross-sectional study. The study included individuals from western Iran aged between 35 and 65 years. The DQI-I was used to assess diet quality and the essential aspects of a healthy diet. Multiple logistic regression analyses were performed to compare DQI-I total score and diabetes. A total of 7,079 individuals were included, including 608 diabetic and 6,471 healthy individuals. The mean DQI-I score was 60.51 ± 8.47 in healthy individuals and 63.12 ± 8.64 in diabetics. The odds of developing diabetes were higher in individuals with a higher DQI-I (adjusted odds ratio: 1.49, 95% CI: 1.30–1.73). The variety was 13.43 ± 4.47 in diabetics and 12.59 ± 4.79 in healthy individuals. Adequacy was 33.23 ± 3.71 in diabetics and 33.79 ± 3.37 in healthy individuals. Moderation was 13.27 ± 6.05 in diabetics and 11.79 ± 5.47 in healthy individuals. The overall balance was 2.88 ± 2.21 in the healthy group and 2.61 ± 2.13 in the diabetics. The macronutrient ratio was 2.15 ± 1.88 in the healthy group and 2.04 ± 1.84 in the diabetics. The fatty acid ratio was 0.72 ± 1.29 in the healthy group and 0.56 ± 1.17 in the diabetic group. The overall balance score was higher in the healthy subjects. The DQI-I total score was higher in diabetics, indicating a positive association between diabetes and the DQI-I. Therefore, the importance of continuous dietary management and education of diabetic patients should be emphasized.

Body mass index is associated with disability at discharge as indicated by the modified Rankin Scale in patients with ischemic stroke: a JROAD-DPC study

ABSTRACT Background Body mass index (BMI) of patients with ischemic stroke (IS) has been associated with prognosis and disability in studies in the United States. Although the Asian population is leaner, the optimal BMI for stroke-related disability remains unknown. Objectives To clarify the association between BMI and disability in patients with IS from a national database in Japan. Methods The present study included 522,421 patients with IS identified in the JROAD-DPC database from April 2016 to March 2020. We used the WHO classification of BMI, which divides Asia-Pacific patients into five groups, to categorize BMI and the modified Rankin Scale (mRS) to assess stroke-related disability at admission and discharge. After multiple imputation for missing values, we conducted a multiple mixed-effect logistic regression analysis for poor mRS score (>2) in September 2023. In addition, we created a restricted cubic spline model between the odds ratio (OR) for poor mRS and BMI. Results The mRS score worsened during hospitalization in 60.1% of the patients with IS, and 45.7% had a poor mRS score at discharge. Overweight patients had the lowest OR of having a poor mRS score (OR: 0.898, 95% confidence interval: 0.895–0.902). The spline curve for the OR for poor mRS score was U-shaped with a BMI of 24.7 kg/m2as the apex value. Conclusion The present study revealed a U-shaped relationship between BMI and stroke-related disability, with overweight patients having the lowest OR for disability at discharge.

Risk Factors for Developing Occupational Back Pain in Electronics Industry Workers: A Cross-Sectional Study

Back pain is an occupation-related problem among workforces. This cross-sectional study aimed to identify the prevalence of back pain and the risk factors of occupational back pain among workers in the electronics industry. In total, 354 electronics workers in Thailand participated in the study. Data were collected using the Musculoskeletal Disorders Severity and Frequency Questionnaire, the Job Content Questionnaire, and ergonomics risk assessment via the Rapid Upper Limb Assessment (RULA). Risk factors of back pain were identified by multiple logistic regression analysis, providing adjusted odds ratios (ORadj) and 95% confidence intervals (95% CI). The study found that most workers were operators (92.09%) and had repetitive work (83.62%). A high ergonomics risk was observed in workers who stood during work (68.49%) and operated machines (71.70%). The 1-month prevalence of developing back pain was 20.62% and the significant factors correlated with back pain were low levels of job control and decision-making (ORadj = 2.26; 95% CI [1.26 ,4.05]), lack of exercise (ORadj = 8.30; 95% CI [1.35, 24.28]), repetitive work (ORadj = 2.94; 95% CI [1.19, 7.29]), and high ergonomic risk level (ORadj = 2.81; 95% CI [1.16, 5.07]). These findings suggest that measures should be implemented by empowering electronics workers to make decisions and control their jobs, as well as promoting health through muscle-stretching exercise, to support back pain prevention.

Elevated intestinal fatty acid-binding protein levels as a marker of portal hypertension and gastroesophageal varices in cirrhosis

We measured intestinal fatty acid-binding protein (I-FABP) levels, a useful marker of small intestinal mucosal injury, in patients with cirrhosis to determine their relationship with liver function and complications. This cross-sectional study included 71 patients with cirrhosis admitted for treatment of cirrhotic complications or hepatocellular carcinoma (cohort A) and 104 patients with cirrhosis who received direct-acting antiviral therapy for HCV (cohort B). I-FABP levels, measured by ELISA, were evaluated relative to hepatic reserve and compared with non-invasive scoring systems for diagnostic performance in cirrhotic complications. The median I-FABP level in both cohorts were significantly elevated in patients with reduced hepatic reserve (CTP grade A/BC cohort A, 2.33/3.17 ng/mL, p = 0.032; cohort B, 2.46/3.64 ng/mL, p = 0.008) and complications with gastroesophageal varices (GEV; GEV (-)/(+) cohort A, 1.66/3.67 ng/mL, p < 0.001; cohort B, 2.32/3.36 ng/mL; p = 0.003). Further, multiple logistic regression analysis identified I-FABP as the only factor contributing to GEV presence in both cohorts, which outperformed non-invasive scoring systems for GEV diagnosis (sensitivity 84.6%; specificity 84.2%; sensitivity 69.6%; specificity 63.8%, respectively). In conclusion, elevated small-intestinal mucosal injury in patients with cirrhosis was related to reduced hepatic reserve and GEV presence. I-FABP levels reflect portal hypertension and may be useful in cirrhosis management.

Clinical characteristics of severe influenza as a risk factor for febrile seizures in children: a retrospective analysis.

To retrospectively analyze the clinical characteristics and independent risk factors of severe influenza combined with febrile seizures, and to provide more basis for early clinical intervention. A total of 161 children with severe influenza were collected as study subjects and divided into convulsive (FC) group (40 cases) and non-convulsive (NFC) group (121 cases) according to whether they had febrile seizures. The demographic characteristics and clinical data of the two groups were analyzed. Multivariate logistic regression was used to analyze the risk factors of severe influenza combined with febrile seizures. The predictive efficacy was evaluated by receiver operating characteristic (ROC) curve analysis. (1) Multiple logistic regression analysis revealed that C-reactive protein (CRP) levels, Serum interleukin 6 (IL-6) levels, Days from onset of Flu symptoms to hospitalization, cerebrospinal fluid protein (CSF-TP) levels and the influenza virus type A (FluA) infection rate were found to be independent risk factors for severe influenza combined with febrile seizures in children. (2) ROC curve analysis showed that the cut-off value of CRP, Serum IL-6, Days from onset of Flu symptoms to hospitalization and CSF-TP were 7.57 mg/L, 9.84 pg/ml, 4.5 days and 194.8 mg/L, respectively. Children with severe influenza with CRP ≥ 7.57 mg/L, Serum IL-6 ≥ 9.84 pg/ml, Days from onset of Flu symptoms to hospitalization ≤4.5 days, CSF-TP ≥ 194.8 mg/L and FluA had a significantly increased risk of febrile seizures. It is useful for clinicians to determine the risk of severe influenza combined with febrile seizures, to adjust the early treatment plan, and to reduce the incidence of critically ill patients.

Hypertension prevalence among the male population aged 35-74 years in Novosibirsk

Aim. To study the prevalence and risk factors of hypertension (HTN), structure and effectiveness of treatment coverage, as well as disease control indicators among the male population aged 35-74 years in Novosibirsk.Material and methods. This cross-sectional study of the Novosibirsk population was conducted in 2021-2023 at the Research Institute for Internal and Preventive Medicine — branch of the Federal Research Center Institute of Cytology and Genetics according to the ESSE-RF3 study protocol. A total of 1200 people aged 35-74 years living in Novosibirsk were examined. The analysis included 600 men. The response rate exceeded 70%. HTN was considered detected in systolic blood pressure (BP) ≥140 mm Hg and/or diastolic BP ≥90 mm Hg and/or in patients taking antihypertensive agents. Awareness was estimated as the proportion of individuals who had previously been informed by a physician about HTN. Treatment effectiveness was considered the proportion of individuals who achieved target BP values while taking antihypertensive therapy. Hypertension control was considered the proportion of individuals who achieved target values among all those examined with HTN. Statistical processing was performed using the SPSS software package (version 13.0). Associations were assessed using multiple logistic regression analysis. The critical significance level of the null hypothesis (p) was 0,05.Results. The medians of systolic and diastolic BP among men in No­vo­sibirsk were 136,0 [126,5; 149,5] and 89,0 [82,0; 95,5] mm Hg, respectively. The prevalence of HTN among men aged 35-74 in Novo­sibirsk was 68,9%, while 81,1% of men in Novosibirsk were aware of HTN. Among men with HTN, 54,7% take antihypertensive agents. The effectiveness of treatment among men in Novosibirsk is 32,3%, while 19,6% of men control the disease. The odds of hypertension occurrence in men with hypertriglyceridemia increased by 3,5 times, with abdominal obesity — by 2 times, with an positive family history for cardiovascular diseases — by 1,6 times, and with each year of life increased by 1,1 times.Conclusion. The prevalence of HTN among men in Novosibirsk is higher in comparison with the average Russian level. Significant risk factors for HTN include abdominal obesity, hypertriglyceridemia, and decreased physical activity. While awareness, treatment coverage, and HTN control among men aged 35-74 in Novosibirsk correspond to Russian trends, treatment effectiveness turned out to be slightly lower than in the Russian population.

Antibody levels versus vaccination status in the outcome of older adults with COVID-19.

BACKGROUNDDespite the currently prevailing, milder Omicron variant of COVID-19, older adults remain at elevated risk of hospital admission, critical illness, and death. Loss of efficacy of the immune system, including reduced strength, quality, and durability of antibody responses, may render generalized recommendations on booster vaccinations inadequate. There is a lack of data on the efficacy of antibody levels in older adults and on the utility of vaccination status versus antibody levels as a correlate of protection. It is further unclear whether antibody levels may be used to guide the timing of booster vaccinations in older adults.METHODSWe conducted a prospective multicenter cohort study comprising hospitalized patients with COVID-19. Anti-SARS-CoV-2 spike antibodies were measured on hospital admission. The primary endpoint was in-hospital mortality. Patients were stratified by age, antibody levels, and vaccination status. Multiple logistic regression and Cox regression analyses were conducted.RESULTSIn total, 785 older patients (≥60 years of age [a]) and 367 controls (<60a) were included. After adjusting for confounders, risk of mortality, ICU admission, endotracheal intubation, and oxygen administration was 4.9, 2.6, 6.5, and 2.3 times higher, respectively, if antibody levels were < 1,200 BAU/mL (aOR, 4.92 [95%CI, 2.59-9.34], P < 0.0001; aOR, 2.64 [95%CI, 1.52-4.62], P = 0.0006; aOR, 6.50 [95%CI, 1.48-28.47], P = 0.013; aOR, 2.34 [95%CI, 1.60-3.343], P < 0.0001). Older adults infected with the Omicron variant were approximately 6 times more likely to die if antibody levels were < 1,200 BAU/mL (aOR, 6.3 [95% CI, 2.43-16.40], P = 0.0002).CONCLUSIONAntibody levels were a stronger predictor of in-hospital mortality than vaccination status. Monitoring antibody levels may constitute a better and more direct approach for safeguarding older adults from adverse COVID-19 outcomes.
