Monocyte-lymphocyte ratio predicts cardiovascular diseases death in individuals with type 2 diabetes.

Previous studies have shown higher cardiovascular mortality risk with higher monocyte-lymphocyte ratio levels in general population. However, the levels of oxidative stress in individuals with type 2 diabetes are higher than those in the general population, which may affect the link between monocyte-to-lymphocyte ratio and cardiovascular disease deaths. And the association between the monocyte-to-lymphocyte ratio and mortality risk in people with type 2 diabetes still be unknown. This study aimed to investigate the prognostic significance of monocyte-to-lymphocyte ratio in type 2 diabetes. This analysis involved 2,954 individuals with type 2 diabetes from the National Health and Nutrition Examination Survey 1999-2010. The National Death Index records through December 31, 2019, was used to determine all-cause and cardiovascular mortality. The prognostic roles were determined using Cox regression models, restricted cubic spline analysis, and time-dependent receiver operating characteristic curve analysis. During an average follow-up period of 12.4 years, a total of 1,007 deaths occurred, while 252 were due to cardiovascular disease. An elevated monocyte-to-lymphocyte ratio level exhibited a significant dose-response relationship with an increased risk of all-cause mortality (1.34 [95% CI 1.12, 1.60] for all-cause mortality [Ptrend = 0.001]). The multivariable-adjusted HR was 1.81 (95% CI 1.25, 2.63) (Ptrend = 0.001) for cardiovascular mortality indicating a U-shaped relationship (Pnonlinear = 0.013). The results of this study indicate a U-shaped relationship between the monocyte-to-lymphocyte ratio and cardiovascular mortality in individuals with diabetes. Both very low and high monocyte-to-lymphocyte ratio monocyte-to-lymphocyte ratio values were found to be associated with increased cardiovascular mortality risk.

Association of body round index with chronic kidney disease: a population-based cross-sectional study from NHANES 1999-2018.

Complex nexuses between obesity and chronic kidney disease (CKD) have been reported. Nevertheless, the link between the body roundness index (BRI), an indicator utilized to measure body fat distribution, and CKD risk has been unexplored. We utilized publicly available data from ten survey cycles (1999-2018) of the National Health and Nutrition Examination Survey (NHANES) in the United States. We examined the association between BRI and CKD risk using multivariable logistic regression, subgroup analysis, interaction tests, and smooth curve fitting. The study ultimately involved 41,953 participants, 3,123 (7.44%) of whom had CKD. Multivariable logistic regression, adjusted for covariates, identified high BRI levels in quartile 4 as a risk factor for CKD (OR = 1.30, 95% CI 1.12-1.50, P = 0.0005). This association remained consistent across subgroups (P for interaction > 0.05). Smoothed curve fitting exhibited a roughly linear positive correlation between BRI and CKD. According to our study, BRI was related to CKD in a roughly linear way, suggesting a novel indicator for improving prevention and treatment for the CKD population. Nevertheless, additional research is needed to identify the association.

The joint effect of vitamin-D status and tobacco exposure on overweight and obesity in children.

This study aimed to explore the combined effects of serum vitamin-D level and tobacco exposure on the risk of overweight and obesity in children. This cross-sectional study analysed the data of 11636 children aged 2-17 years from the National Health and Nutrition Examination Surveys database between 2007 and 2018. Univariable and multivariate weighted logistic regression models were used to analyse the associations of serum vitamin-D or cotinine levels with overweight and obesity in children as well as the combined effects of serum vitamin-D and cotinine on the risk of overweight and obesity in children. Subgroup analysis was performed in terms of gender, age, race and household smokers. OR with corresponding 95 % CI was presented. The elevated risk of overweight and obesity in children was found in those with serum vitamin-D < 20 ng/ml (OR = 1·44, 95 % CI: 1·29, 1·61). Also, the odds of overweight and obesity in children was 1·14 (OR = 1·14, 95 % CI: 1·01, 1·29) in children with cotinine ≥ 0·05 ng/ml. Relative to participants with serum vitamin-D ≥ 20 ng/ml and cotinine < 0·05 ng/ml, increased risk of overweight and obesity was identified in those with serum vitamin-D < 20 ng/ml and cotinine < 0·05 ng/ml (OR = 1·45, 95 % CI: 1·26, 1·68) and serum vitamin-D < 20 ng/ml and cotinine ≥ 0·05 ng/ml (OR = 1·62, 95 % CI: 1·38, 1·91). Serum vitamin-D and cotinine exposure had combined effects on the risk of overweight and obesity in children.

Metrics of physiological network topology are novel biomarkers to capture functional disability and health.

Physiological networks are highly complex, integrating connections among multiple organ systems and their dynamic changes underlying human aging. It is unknown whether individual-level network could serve as robust biomarkers for health and aging. We used personalized network analysis to construct single sample network and examine the associations between network properties and functional disability in the Rugao Longevity and Aging Study (RuLAS), the China Health and Retirement Longitudinal Study (CHARLS), the Chinese Longitudinal Healthy Longevity Survey (CLHLS), and the National Health and Nutrition Examination Survey (NHANES). We observed impairments in interconnected physiological systems among long-lived adults in RuLAS. Single sample network analysis was applied to reflect the co-occurrence of these multi-system impairments at the individual level. The ADL-disabled individuals' networks exhibited notably increased connectivity among various biomarkers. Significant associations were found between network topology and functional disability across RuLAS, CHARLS, CLHLS and NHANES. Additionally, network topology served as novel biomarkers to capture risks of incident ADL disability in CHARLS. Furthermore, these metrics of physiological network topology predicted mortality across four cohorts. Sensitivity analysis demonstrated that prediction performance of network topology remained robust, regardless of the chosen biomarkers and parameters. These findings showed that metrics of network topology were sensitive and robust biomarkers to capture risks of functional disability and mortality, highlighting the role of single sample physiological networks as novel biomarker for health and aging.

Expert Opinion on the Role of Sacubitril/Valsartan in the Management of Hypertension in India.

Hypertension, a key modifiable risk factor for cardiovascular diseases (CVD), significantly contributes to premature death and morbidity worldwide. Despite stabilization in age-adjusted global prevalence, the absolute number of hypertensive individuals doubled from 2000 to 2010, largely due to increases in low- and middle-income countries. In 2021, only 21% of hypertensive individuals globally had effective blood pressure (BP) control. In India, hypertension is the leading risk factor for death and disability, with prevalence rates of 24% in men and 21% in women, as reported by the 2019-2020 National Family Health Survey (NFHS-5). Alarmingly, just 25% of rural and 38% of urban hypertensive Indians are undergoing treatment, with only 10% and 20% achieving BP control, respectively. This highlights the hypertension paradox, where clinical inertia and hesitancy in intensifying BP-lowering therapy persist despite the availability of antihypertensive drugs. This expert opinion paper aims to provide a comprehensive evaluation of sacubitril/valsartan in hypertension management, leveraging insights from its approved use in heart failure and examining its benefits and challenges across diverse hypertensive populations. The formulation of this expert opinion involved employing evidence-based methodologies and utilizing all available data. The document underwent scrutiny by expert cardiologists, whose clinical experiences and examination of the evidence and guidelines informed the formation of the expert opinion. This expert opinion paper provides a thorough and informed evaluation of sacubitril/valsartan, highlighting its potential to address unmet needs in BP control, particularly in challenging cases such as resistant hypertension and chronic kidney disease.

Functional difficulty among children in Malaysia - findings from the National Health and Morbidity Survey (NHMS) 2019.

Data on child functioning and disability are important for public policy development which aimed at reducing child disability prevalence and strengthening the provision of appropriate and timely health care services. This study reports the prevalence of functional difficulty in Malaysian children aged 2-17 years and its associated sociodemographic factors and epilepsy. Data on children aged 2-17 years (n = 4576) were generated from the National Health and Morbidity Survey (NHMS) 2019, a population-based cross-sectional survey. Functional difficulty in children was assessed using the United Nations Children's Fund (UNICEF)/Washington Group on Disability Statistics (WG) Child Functioning Module (CFM). The questionnaires were administered to the parents or guardians of the children via face-to-face interviews. Functional difficulty, defined as having difficulty in at least one domain, was examined for its prevalence and associations with sociodemographic variables and the epilepsy variable in children using descriptive analysis and multiple logistic regression. The overall prevalence of functional difficulty among children aged 2-17 years was 4.7%. Multiple logistic regression analysis revealed that older children, children from households whose heads of household had a lower education level and children who have epilepsy were significantly more likely to experience functional difficulty (p < 0.05). Children of Chinese ethnicity were less likely to experience functional difficulty compared to children of Malay ethnicity. This study provides baseline findings on the prevalence of functional difficulty among children in Malaysia using nationally representative data. Although the prevalence was relatively low, the information is important for the planning of strategies to improve the development and well-being of children in Malaysia and for achieving the Sustainable Development Goals (SDGs).

Impacts of inequalities in utilization of key maternal health service on fertility preference among high parity women in four selected regions of Ethiopia.

Fertility is one of the three main components which determines the size, structure, and composition of a population, and fertility preferences are important measures for forecasting fertility levels of a population. Therefore, this study aims to assess the impacts of the inequalities in the utilization of key maternal health services on fertility preference among high parity women in four selected regions (i.e., Afar, Beninshangul-Gumuz, Gambella and Somali) of Ethiopia. The study used data collected for the 2016 Ethiopian Demographic and Health Surveys (EDHS) survey. It includes a total of 977 high parity women (104 urban and 873 rural) residing in the four regions of the study. Bivariate logistic regression was used to select the potential variables by using a cut off p-value < 0.2 and then the multivariable logistic regression analyses were performed to assess the association between the selected explanatory variables (i.e., control and exposure variables) and the outcome variable (i.e. fertility preference). Further, the study employed a Population Attributable Fractions (PAFs) to examine the population level impacts of the inequalities in maternal and child health service variables on fertility preference. The results showed that religion, household wealth index, place of delivery and contraceptive use were significantly associated with fertility preference. The results of the PAFs analysis indicated that contraceptive use had the biggest impact (80%), meaning that non-use of contraceptive increased fertility preference among women in the four regions. Similarly, out of health facility delivery increased fertility preference by 37%. The study findings underscore the critical factors influencing women's fertility preferences in the studied regions. Low utilization of maternal health services had an impact on fertility preference, accounting for more than half of the observed variations in fertility preferences. To address this issue, targeted interventions are recommended: enhancing access to maternal health services, strengthening fertility control programs, promoting the benefits of using these services, and actively addressing inequalities.

Predictive accuracy of the logit model to determine factors affecting delivery and postnatal care services utilization in Tanzania

PurposeThis paper examines factors affecting the delivery care (DC) and postnatal care (PNC) services utilization in Tanzania using the predictive accuracy of the binary logit model by including DC as among the predictors of PNC utilization.Design/methodology/approachThe study used secondary data from the Tanzania Demographic and Health Survey and Malaria Indicator Survey (2022) based on a sample of 13,266 women aged 15–49. Binary logit was used to analyze the association between independent variables and each binary dependent variable, followed by a stepwise likelihood ratio test for binary logistic regression analysis to select the most important predictors associated with DC and PNC. Odds ratios were used to predict the likelihood of the occurrence of significant explanatory variables in explaining the outcomes.FindingsThe results showed that the type of place of residence, wealth index, region, highest educational level, husband/partner’s level of education and respondent’s occupation were significant predictors of DC utilization. In contrast, the woman’s age, region, highest educational level, wealth index, DC and husband/partner’s educational level were significant predictors of PNC utilization. Public health interventions are needed to promote and increase the utilization of delivery and postal care services. The targets should be poor women and those residing in rural or remote areas.Originality/valueIncluding DC as a predictor variable (which was not used before) in PNC utilization improved the predictive power of the model and the robustness of the results.

Identification of sensitive periods of weight status transition over the lifespan in Chinese population.

The prevalence of high body mass index (BMI) is increasing in both children and adults worldwide. However, it is unclear whether vulnerabilities to maintenance and transition of weight status vary throughout the lifespan. We aimed to characterize dynamic transitions of weight statuses across different life stages and to identify the sensitive periods for maintenance, onset, and resolution of obesity. This longitudinal study included a total of 23,179 participants aged 6-80 years with 95,994 BMI measurements from the China Health and Nutrition Survey 1989-2015. To examine the heterogeneity in transitions of weight statuses across different life stages, we divided participants into 8 sub-cohorts based on baseline ages by 10-year intervals, i.e., 6-10 years, 11-20 years, 21-30 years, 31-40 years, 41-50 years, 51-60 years, 61-70 years, and 71-80years. We estimated the probabilities of transitioning between weight statuses at a given follow-up year by baseline age using generalized linear mixed-effects models. The predicted prevalence of obesity decreased from 6years, bottomed at around 20 years, increased thereafter, peaked at around 55 years, and then decreased gradually. In general, participants with underweight had lower probabilities of maintaining the same status compared to those with normal weight, overweight, or obesity for all age groups. For 10-year follow-up, individuals aged 21-30 years had the highest probabilities of transitioning from normal weight to obesity and transitioning from overweight to obesity compared to those in other age groups. Individuals aged 6-20 years had the highest probabilities of transitioning from obesity to normal weight and transitioning from overweight to normal weight. Individuals in all adult age groups had higher probabilities of maintaining obesity status than children and adolescents. Young adulthood is the most sensitive period for obesity onset, whereas childhood and adolescence are the most sensitive periods for obesity resolution. The findings suggest the heterogeneity of susceptibilities to weight status transitions across different life stages and highlight the importance of the development of age-appropriate approaches for the prevention and intervention of obesity.

Systemic immune-inflammation mediates the association between Klotho protein and metabolic syndrome: findings from a large-scale population-based study.

This study utilized large-scale population data from the National Health and Nutrition Examination Survey (NHANES) to elucidate the relationship between the Klotho protein and metabolic syndrome along with its components. We further investigated the possible mediating effect of inflammation on these relationships. Our objective was to identify biomarkers for risk stratification and potential therapeutic targets for metabolic syndrome. This study enrolled 13,119 participants aged 40-79 years, spanning five NHANES cycles from 2007 to 2016, with complete information on metabolic syndrome and the Klotho protein. The definition of metabolic syndrome followed the criteria of the National Cholesterol Education Program-Adult Treatment Panel III. Survey-weighted logistic regression and subgroup analysis were used to explore the associations between serum Klotho protein levels and metabolic syndrome, along with its components. Mediation analysis was performed to investigate the mediating effects of inflammation-related markers, including white blood cells, neutrophils, lymphocytes, monocytes, the neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR), the systemic immune-inflammation index (SII) and the monocyte-to-HDL ratio (MHR), with the aim of elucidating how the Klotho protein influences the onset and progression of metabolic syndrome. The study participants had an average age of 56.06 years (95% CI: 55.76-56.37), with a Klotho protein concentration of 798.10 pg/ml (95% CI: 656.50-980.50) and a 43.77% prevalence of metabolic syndrome (n = 5742). In the crude model, Klotho was negatively correlated with metabolic syndrome and its components, including central obesity, hypertension, and hypertriglyceridemia. After adjusting for all confounding factors, Klotho was demonstrated to be negatively associated only with metabolic syndrome (OR: 0.82, 95% CI: 0.70-0.97), hypertension (OR: 0.83, 95% CI: 0.70-0.98), and hypertriglyceridemia (OR: 0.78, 95% CI: 0.67-0.91). Subgroup and interaction analyses revealed significant interactions between age, sex, race/ethnicity, body mass index, and Klotho. Additionally, mediation analysis demonstrated that leukocytes, neutrophils and monocytes accounted for 34.78%, 31.91% and 7.13%, respectively, of the associations between Klotho and metabolic syndrome. The serum concentration of Klotho protein was negatively associated with metabolic syndrome, with the relationship being partly mediated by systemic immune inflammation. The findings of this research revealed that the Klotho protein may be a valuable biomarker for risk stratification and a potential therapeutic target for metabolic syndrome.

Association between non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol ratio (NHHR) with depressive symptoms: recent findings from NHANES 2005–2018

BackgroundThe ratio of non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol (NHHR) index is a relatively new composite lipid index, the relationship between NHHR and depression is unclear from the current study. The primary aim of our study was to examine the association between the prevalence of depression and NHHR in a US population.MethodsThe National Health and Nutrition Examination Survey (NHANES) provided the data for our investigation from 2005 to 2018. and primarily included participants who contained complete data on NHHR and depression in U.S. adults (age ≥20 years). Associations between NHHR and depression were assessed using multifactorial logistic regression analysis, subgroup analysis, and smoothed curve fitting.ResultsIn our study, 29,561 subjects in total showed a mean NHHR index of 3.12± 1.58,A noteworthy positive correlation was observed between NHHR and depression in multifactorial logistic regression analysis. Subgroup analyses and tests of interaction showed that gender, age, ethnicity, PIR, smoking, alcohol consumption, coronary heart disease, diabetes mellitus, hypertension, and stroke did not influence the NHHR and the association between depression (P for interaction &amp;gt; 0.05), whereas two stratification factors, BMI and sleep disturbance, may be potential factors in the association between NHHR and depression (P for interaction &amp;lt; 0.05).ConclusionAccording to our present study, if the level of NHHR rises in American adults, their likelihood of developing depression also increases.

Distinct characteristics of MetALD (metabolic dysfunction-associated steatotic liver disease with greater alcohol consumption) in the general population.

The term MetALD has been introduced to describe individuals who have metabolic dysfunction-associated steatotic liver disease (MASLD) with greater alcohol consumption, according to the new nomenclature for steatotic liver disease (SLD). This study aims to evaluate the prevalence and clinical characteristics of MetALD in the general population. This study is a retrospective, cross-sectional analysis that utilizes the population-based data from the Korea National Health and Nutrition Examination Survey (KNHANES) undertaken between 2019 and 2021. A total of 16521 participants aged over 18years were included in the analysis. The presence of hepatic steatosis was determined based on a hepatic steatosis index of 36 or higher. The prevalence of MetALD was 2.8% (95% confidence interval, 2.5-3.2). Individuals with MetALD were predominantly men (85.4%) and tended to be younger compared to those with MASLD. They showed a higher prevalence of hypertension and had significantly higher levels of fasting glucose, triglycerides, high-density lipoprotein cholesterol, and creatinine compared to individuals with MASLD. The average daily total energy intake was higher in the MetALD group. In addition, the MetALD group had a lower proportion of unemployment with higher income compared to the MASLD group. Patients with MetALD showed distinct clinical characteristics from those with MASLD. The characteristics of MetALD were similar to those with alcohol-related liver disease. Further analysis of MetALD across various regions and ethnic groups would be needed.

Trends in Toddler Diet Quality in the United States: 1999 to 2018.

Diet quality has improved over time for US adults and youth aged ≥2 years. Trends over time and disparities in the diet quality of toddlers 12 through 23 months old have not been documented. Our objective was to investigate the direction and magnitude of toddler diet quality trends from 1999 to 2018 overall and by household socioeconomic status. This serial cross-sectional analysis of National Health and Nutrition Examination Survey (NHANES) data was performed with 2541 toddlers from 10 NHANES cycles from 1999 to 2018. Dietary intake was measured by NHANES study staff using proxy-reported 24-hour recalls. Healthy Eating Index-Toddlers-2020 total scores (0-100 points, higher scores indicate healthier diets) and component scores were calculated from the 24-hour dietary recalls using the population ratio method. Multivariable linear regression was used to evaluate the association between time in years (measured as the midpoint of each NHANES cycle) and diet quality. Toddler diet quality improved significantly from 1999 to 2018 (P < .001), from 63.7 points on average in 1999-2000 to 67.7 points in 2017-2018. A significant positive linear trend in total diet quality was observed for all socioeconomic status groups (P < .05). Several dietary component scores improved, as follows: Whole Fruits (P < .001), Whole Grains (P = .016), Fatty Acids (P = .002), Refined Grains (P = .009), and Added Sugars (P < .001). Scores did not significantly change for Total Fruit, Total Vegetables, Greens and Beans, Dairy, Total Protein Foods, Seafood and Plant Proteins, Sodium, or Saturated Fats. From 1999 to 2018, toddler diet quality improved significantly, but mean scores still fell short of dietary guidance.

Associations Between Relative Lower and Upper Body Strength and Hyperinsulinemia in US Adults: 1999-2002 and 2011-2014 NHANES.

Churilla, JR, Boyer, WR, Richardson, MR, and Williams, CC. Associations between relative lower and upper body strength and hyperinsulinemia in U.S. Adults: NHANES 1999-2002 and 2011-2014. J Strength Cond Res XX(X): 000-000, 2024-Skeletal muscle (SM) is an insulin-sensitive tissue that aids in glucose homeostasis. Insulin resistance leads to chronic hyperglycemia and type 2 diabetes. Previous evidence suggests that greater SM strength and size improve insulin dynamics. The primary aim of this study was to examine the association(s) between relative lower and upper body strength and hyperinsulinemia in a nationally representative sample of US adults. Samples of adult (≥50 years) subjects in the 1999-2002 (N = 1,097) and adults (≥20 years) in the 2011-2014 (N = 2,576) National Health and Nutrition Examination Survey were used in the analyses. Significance was set at p ≤ 0.05 for regression models. Quartiles (Q) of relative lower body strength (RLBS [N·BMI-1]) and relative grip strength (RGS [kg·BMI-1]) were created. Hyperinsulinemia was calculated using the weighted 75th percentile of log-fasted insulin among adults without diabetes. Inverse dose-response relationships were found for decreasing prevalence estimates of hyperinsulinemia by increasing Q of both RLBS and RGS. Similar dose-response associations were revealed for increasing Q of both RLBS and RGS and mean insulin concentrations. Following adjustment for demographic and lifestyle variables, subjects in Q2, Q3, and Q4 of RLBS were found to have significantly lower odds of hyperinsulinemia (OR 0.58 [P = 0.05], OR 0.38, OR 0.22 [p < 0.05 for both], respectively). Subjects in Q2, Q3, and Q4 of RGS were also found to have lower odds of hyperinsulinemia (OR 0.30; OR 0.14; OR 0.05 [p < 0.0001 for all]), respectively. These data suggest RLBS and RGS may both be favorably associated with insulin homeostasis.

A U-shaped association between composite dietary antioxidant index and migraine in US adults: a nationwide cross-sectional study.

The field of dietary therapies for migraine has grown in popularity. Less research has been conducted to establish the relationship between migraine and the composite dietary antioxidant index (CDAI), a crucial indicator for evaluating the overall combined effects of multiple dietary antioxidants. Therefore, this study addressed this gap based on the National Health and Nutrition Examination Survey (NHANES) database. Multivariate logistic regression equations were used to investigate the relationship between CDAI and migraine, and smoothed-fitted curves were plotted. After a nonlinear relationship was discovered, the recursive algorithm and a two-stage linear regression model were employed to calculate the turning point. Additional stratified analyses were performed to explore differences between populations. This study included a total of 9,190 participants aged 20 years old or older. A U-shaped association was observed between the CDAI and migraine, with an inflection point of 0.2. They were negatively correlated before the inflection point with OR of 0.93 (95% CI = 0.88-0.97) and positively correlated after the inflection point with OR of 1.04 (95% CI = 1.01-1.07). This U-shaped relationship persisted among people aged <60 and ≥60 years, women, and people with BMI <30 and ≥30. We identified a U-shaped association between CDAI and migraine in the U.S. adult population. Further case-control studies and experimental research are needed to explore the underlying mechanisms of action.

Association between secondhand smoke and liver injury among US non-smoking adults: Mediation analysis of body mass index in the NHANES.

Liver injury is a primary factor in the pathogenesis of most liver diseases, which can lead to liver failure. Secondhand smoke (SHS) is a serious public problem. This research explored the correlation between SHS and the indicators of liver injury. This cross-sectional study was based on the National Health and Nutrition Examination Survey (NHANES) 2011-2016. The relationship between SHS and indicators of liver injury was explored by the weighted linear regression model and smooth curve fitting. The weighted threshold saturation effect model tested the relationship and inflection point between them. Mediation analyses were used to explore whether body mass index (BMI) mediates the correlation between SHS and liver injury indicators. Our cross-sectional study included 3811 non-smoking participants (aged 20-80 years). The full covariate adjustment model (β= -0.05; 95% CI: -0.08 - -0.02) showed a significant and negative correlation between log cotinine and albumin (ALB). Compared to the unexposed group, the ALB, and total protein (TP) were decreased by 0.16 g/dL, 0.26 g/dL in the heavy exposure group [ALB: -0.16 (-0.26 - -0.05), TP: -0.26 (-0.38 - -0.13)], respectively. Smoothed curve fitting revealed a nonlinear relationship between log cotinine and fibrosis-4 index (FIB-4 score), with the inflection point of log cotinine at -1.72. When log cotinine was < -1.72, the log cotinine significantly and positively correlated with the FIB-4 score (β=0.27; 95% CI: 0.06-0.49). BMI partially mediated the effect of SHS exposure on ALB or TP. SHS has harmful effects on the liver in never-smoking adults. BMI partially mediated the effect of SHS exposure on ALB or TP. More prospective and basic research in the future is necessary to focus on validating our results.

Synergistic impact of Composite Dietary Antioxidant Index and physical activity on fatty liver disease

BackgroundThe relationship between dietary antioxidants and fatty liver disease remains a topic of debate. This study aimed to examine the association between the Composite Dietary Antioxidant Index (CDAI) and nonalcoholic fatty liver disease (NAFLD)/metabolic-associated fatty liver disease (MAFLD).MethodsThe study analyzed data from the 2003–2018 cycles of the National Health and Nutrition Examination Survey. The study included 16,321 individuals aged 20–85 years. Food and nutrient intake data were based on the 24-h recall method. Multivariate logistic regression models were employed to examine the relationship between CDAI and NAFLD/MAFLD.ResultsIn the fully adjusted multivariate logistic regression model, CDAI demonstrated a significant negative correlation with NAFLD and MAFLD. Mediation analysis showed that inflammatory factors partially mediated the relationship between CDAI and NAFLD/MAFLD prevalence. The combination of high CDAI levels with effective physical activity was associated with a greater reduction in NAFLD/MAFLD prevalence than high CDAI levels alone.ConclusionOur study highlighted a negative association between CDAI and NAFLD/MAFLD, mediated by inflammatory factors. Additionally, participants with characteristics of active physical activity and high levels of CDAI were more strongly correlated with the reduced prevalence of NAFLD/MAFLD. Further research in clinical cohorts should be conducted to comprehensively investigate the impact of CDAI on NAFLD/MAFLD prevalence.

Magnesium depletion score and depression: a positive correlation among US adults

BackgroundThe Magnesium depletion score (MDS) serves as a novel metric for quantifying magnesium deficiency in the human body, comprehensively assessing four indicators: diuretic use, proton pump inhibitor use, estimated glomerular filtration rate, and alcohol abuse. However, there have been no studies examining the potential association between MDS and depression.MethodsThe study population for this cross-sectional study comprised adults from the National Health and Nutrition Examination Survey database from 2009 to 2018. Participants with a score of 10 or above on the Patient Health Questionnaire-9 were defined as having depression. We employed multivariable logistic regression models to investigate the association between MDS and depression. Furthermore, subgroup analyses were conducted to assess potential differences in this association among populations with diverse characteristics.ResultsA total of 13,197 participants were included in this study. After adjusting for all covariates, a significant positive correlation was observed between MDS and depression. Specifically, for every unit increase in MDS, the likelihood of developing depression increased by 13% (OR = 1.13, 95% CI: 1.04–1.22, p = 0.0025). This positive correlation was consistent across MDS groups, with a 19% increase in depression likelihood in the medium group (OR = 1.19, 95% CI: 1.01–1.41, p = 0.0404) and a 58% increase in the high group (OR = 1.58, 95% CI: 1.21–2.07, p = 0.0007), using the low subgroup as a reference. Subgroup analyses revealed significant differences in the relationship between MDS and depression across races, marital statuses, and hypertension status.ConclusionOur study has uncovered a significant positive association between MDS and depression. Reducing MDS in individuals may play a positive role in both the prevention and treatment of depression.

Exploring the Impact of Instrument-Assisted Soft Tissue Mobilization on Functional Measures and Quality of Life in Knee Osteoarthritis Patients: A Randomized Controlled Trial

Background: Knee osteoarthritis (KOA) is a prevalent disabling condition characterized by pain, stiffness, and functional limitations, significantly impacting quality of life, particularly among older adults. Instrument-assisted soft tissue mobilization (IASTM) is a technique that has shown promise in reducing pain and increasing the range of motion. Objectives: This study aimed to investigate the effects of IASTM on functional measures and quality of life in KOA patients. Methods: Thirty participants with unilateral KOA were randomized into IASTM and sham groups. The intervention consisted of four sessions over two weeks, combining IASTM with exercise therapy. Functional performance was assessed using the 6-minute walking test (6MWT) and the timed up and go test (TUG). Quality of life was evaluated using the 36-item short-form health survey (SF-36) and the Lequesne Algofunctional Index (LAI) Questionnaires. Results: A mixed ANOVA revealed significant improvements in functional performance in both groups after treatment in the 6MWT (P &lt; 0.001) and TUG (P = 0.003) tests. Significant improvements were observed in the SF-36 subgroups for physical functioning (P = 0.002), role limitations due to physical problems (P &lt; 0.001), energy/vitality (P &lt; 0.001), pain (P &lt; 0.001), and total score (P &lt; 0.001). There was also a significant time*group interaction effect for role limitations due to emotional problems (P = 0.005), with the IASTM group showing improvement after treatment while the sham group experienced a decline. The LAI questionnaire also indicated significant improvements in both groups (P &lt; 0.001) after treatment. Conclusions: Both IASTM and sham interventions, combined with exercise therapy, led to improvements in functional measures and quality of life. However, the IASTM group exhibited a more pronounced positive trend in the 6MWT and TUG tests, as well as a significant interaction effect for emotional role limitations. These findings suggest that while exercise alone can improve function and quality of life, the addition of IASTM may further enhance these outcomes, supporting its integration into KOA management strategies to improve activities of daily living and overall quality of life.

Trend of immunization &amp; gap in vaccine doses as observed in National Family Health Survey rounds in India

Background &amp; objectives Immunization is an efficient and cost-effective way of lowering the infectious disease related morbidity and mortality in the community. The current study reviewed the trend of immunization, gaps in doses of vaccine given at the same time and gaps between the doses of same vaccine from National Family Health Survey (NFHS 1-5) rounds. Methods The current study extracted data from all five NFHS rounds conducted from 1992-93 to 2019-21. The study analyzed the State-wise and demography-wise distribution of trends of immunization from NFHS-1 to NFHS-5. State wise distribution of change in vaccination coverage between NFHS-4 and 5 was analyzed. The study also assessed the State-wise trends of fully vaccinated and unvaccinated children from NFHS 1-5. Results The northeastern States had maximum gap between the vaccination given at birth i.e., 47.3 per cent between BCG and Hepatitis B, and 32.8 per cent between BCG and birth dose of OPV in Manipur in NFHS -5. A gradual rise in the percentage of male (40.2%) and female (41.9%) childrens’ vaccination was found across the NFHS rounds with reduction in gap between the male and female vaccination from NFHS-1 (2.6%) to NFHS-5 (0.9%). The percentage of vaccination decreased proportionately with birth order. The vaccination coverage has increased in both urban and rural population, but the rise was higher in rural (45.9%) areas than urban (24.8%). An increase in percentage of fully vaccinated children by 41.2 per cent and decrease in percentage of non-vaccinated children by 26.4 per cent was observed from NFHS-1 to NFHS-5. Interpretation &amp; conclusions Our analysis clearly suggests that immunization coverage has improved over a period of time but the variability in vaccine coverage across States and gap in vaccine doses needs attention of the policy makers to cover this for achieving our national immunization goals.
