RESUMEN
Background: At present, there is a dearth of comprehensive data at the global, national, and regional levels regarding the adult non-alcoholic fatty liver disease (NAFLD) prevalence. This cross-sectional study aims at ascertaining the prevalence of NAFLD and non-alcoholic steatohepatitis (NASH), utilizing body mass index (BMI) as a determining factor. Methods: Based on the NHANES database, sigmoidal fitting curves were generated to establish the relationship between BMI and the risk of NAFLD/NASH. Utilizing BMI data from the NCD Risk Factor Collaboration (NCD-RisC) database at both global and regional levels, the prevalence of NAFLD/NASH among adults was estimated from 1975 to 2016, encompassing global, regional, and national perspectives. Additionally, projections were made to forecast the prevalence of adult NAFLD/NASH from 2017 to 2030. Results: In 2016, the global prevalence of NAFLD was 41.12% for males and 37.32% for females, while the global prevalence of NASH was 15.79% for males and 16.48% for females. The prevalence of NAFLD/NASH increased with higher BMI in both genders. Over the period from 1975 to 2016, there has been a gradual increase in the global prevalence of NAFLD/NASH in adults, and this trend is expected to continue between 2017 and 2030. In males, the prevalence of adult NAFLD/NASH was found to be highest in High-income Western countries, while it was highest in Central Asia, Middle East, and North African countries after 1995. Conclusions: The prevalence of adult NAFLD/NASH has been observed to increase annually, with significant variations in burden across different countries and regions.
RESUMEN
Background This study aims to evaluate the prognostic significance of the modified Glasgow Prognostic Score (mGPS) in patients with metastatic colorectal cancer (mCRC). Methodology A retrospective analysis was conducted among 65 patients diagnosed with stage IV colorectal cancer who received treatment and follow-up at the Oncology Department of Elias Emergency University Hospital in Bucharest, Romania, from January 2016 to January 2024. Patient data were collected, including demographic information, tumor characteristics, and laboratory parameters. The mGPS was calculated based on serum albumin and C-reactive protein (CRP) levels. Patients were stratified into the following three mGPS categories: 0 (normal CRP and albumin), 1 (elevated CRP or hypoalbuminemia), and 2 (elevated CRP and hypoalbuminemia). Results Of the 65 patients included, 33 (50.8%) were male and 32 (49.2%) were female, with a mean age of 63.7 years. According to mGPS, 25 (38.5%) patients scored 0, 30 (46.2%) scored 1, and 10 (15.4%) scored 2. The median overall survival (OS) was 53 months (95% confidence interval (CI) = 23.512-82.488), and the median progression-free survival (PFS) was 23 months (95% CI = 19.244-26.756). Although numerical differences in the median PFS and OS were observed between treatment groups, these differences were not statistically significant (PFS: p = 0.292; OS: p = 0.5). Conclusions The mGPS is a useful prognostic tool in mCRC, providing insights into patient survival outcomes. However, further studies with larger sample sizes are needed to validate these findings and clarify the role of mGPS in guiding clinical decision-making for mCRC patients.
RESUMEN
Objective: The objective of this study is to independently assess skeletal muscle index (SMI) and body mass index (BMI) as prognostic determinants for renal cell carcinoma (RCC) and investigate their correlation with surgical outcomes. Patients and methods: A retrospective cohort study of 524 RCC patients diagnosed between August 2010 and July 2018 was conducted using data from the Zealand University Hospital Renal Cancer Database in Denmark. Patient information was extracted from electronic patient records and the National Cancer Registry and encompassed demographics, clinical factors, tumour characteristics and surgical details. SMI was calculated from a single third lumbar vertebra (L3) axial computed tomography (CT) image via CoreSlicer software and classified into high using gender-specific thresholds. Primary outcomes focused on complications within 90 days as well as survival outcomes, and their relation with both SMI and BMI. Multivariable analysis assessed SMI's independent prognostic significance in RCC. Results: Among 524 patients, 18.5% experienced complications, with high SMI correlating significantly (p = 0.018) with a 72% higher complication risk. High SMI patients had a 22.7% complication rate compared to 14.5% in the low SMI group. High SMI was also linked to prolonged survival (110.95 vs. 94.87 months; p = 0.001), whereas BMI showed no significant survival differences (p = 0.326). Multivariable analysis (n = 522) revealed high SMI associated with improved survival (hazard ratio [HR] = 0.738; 95% CI, 0.548-0.994; p = 0.046). Advanced T-stage significantly impacted mortality (T2: HR = 2.057; T3: HR = 4.361; p < 0.001), and each additional year of age raised mortality risk by 4.3% (HR = 1.043; p < 0.001). Conclusions: Higher SMI increases the risk of postoperative complications, yet it significantly improves overall survival rates. Different BMI categories lack RCC prognostic significance. The increasing incidence in RCC calls for the use of CT scan to assess SMI and aid treatment planning in patients who might benefit from preoperative interventions.
RESUMEN
Background: Dupilumab is a monoclonal antibody used for the treatment of moderate/severe atopic dermatitis (AD). In recent years, several studies have confirmed the positive association between AD and overweight/obesity, and a report demonstrated the effect of weight reduction on the improvement of AD symptoms. Methods: The weight of 170 patients under treatment with dupilumab was recorded at baseline and after 48 weeks (T48). Clinical monitoring was mainly conducted using the Eczema Area and Severity Index (EASI). The study aimed to assess a possible correlation between the clinical outcome of dupilumab therapy and BMI. Results: Although not statistically significant, patients with a BMI < 25 have a higher EASI percentage improvement than patients with a BMI ≥ 25 at any time point, and the percentage of overweight and obese patients that does not reach EASI-75 at T48 is higher compared to normal-weight patients (13.5% vs. 5.9%). Despite this, in the multivariate regression analysis, no baseline characteristic, including BMI, appears to increase the risk of not reaching EASI-75. In addition, the results show no differences in BMI between baseline and T48 in any age/sex group. Conclusions: The results suggest that overweight and obese patients have a lower response to dupilumab when considering the EASI score, but this difference does not appear to be clinically significant. Furthermore, dupilumab treatment does not seem to impact weight.
RESUMEN
Introduction Obesity can develop from childhood through adulthood and is influenced by genetics, family, and environmental factors. Parenting educational style is believed to contribute to an individual's future weight status. This study aims to assess the connection between parenting educational style and weight-related issues. Methods The study involved 487 participants, including either the mother and/or father and their school-age child, aged 6-11, at a primary care unit in Mexico. Fifty-two records were excluded due to incomplete questionnaires, electronic records, and refusal of informed consent. The study group consisted of 435 adults and children who completed an adapted version of the Parenting Styles and Dimensions Questionnaire (PSDQ) tailored for the Mexican population. The researchers also gathered anthropometric measurements of the primary caregiver (parent) and the child from the electronic record to calculate their BMI and nutritional status. We used IBM SPSS Statistics for Windows, Version 25.0 (Released 2017; IBM Corp., Armonk, NY, USA) to analyze the data. The Pearson Chi-square and Fisher's exact test were applied to examine interaction terms between variables, revealing a statistically significant p-value of <0.05. Results Out of the 435 patients examined, there were 229 (52.6%) children and 206 (47.3%) adult patients. Grade 2 obesity was present in 90 (39.3%) school-age children and 104 (50.5%) adult patients. The family's parenting educational style, as determined by the PSDQ questionnaire, was found to be permissive in 143 (69.4%) patients, authoritarian in 33 (16.0%) patients, and authoritative in 30 (14.6%) patients. Conclusions Parenting educational style and the PSDQ tool can be used to assess how parents influence the development of obesogenic home environments. We observed that a permissive parenting educational style was linked to a more obesogenic environment, whereas an authoritative parenting educational style was linked to a less obesogenic environment.
RESUMEN
BACKGROUND: Unhealthy weight control behaviors (UWCBs) involve weight control strategies to reduce or maintain weight, such as fasting, taking diet pills, and vomiting or taking laxatives. UWCBs in teenagers can escalate into severe health issues such as eating disorders. Understanding the trends of UWCBs and their association with risk behaviors in teenagers is crucial, as early intervention and prevention strategies are pivotal. METHODS: This study utilized eight waves of the youth risk behavior surveillance system (YRBSS) data from 1999 to 2013. Our primary outcome was UWCBs engagement. We used multinomial logistic models to analyze the association between UWCBs and risk behaviors among adolescents including driving after alcohol consumption, suicide attempts, smoking, alcohol use, and sexual intercourse. RESULTS: Among 109,023 participants, UWCBs prevalence was 16.64%. Body Mass Index (BMI) was significantly associated with UWCBs risk. In addition, we found the intention of weight management confounded the relationship between BMI and UWCBs. The unadjusted logistic regression indicated a monotone-increasing association between BMI and the risk of UWCBs. In contrast, the adjusted logistic regression indicated a U-shaped curve with the lowest (BMI < 17 kg/m2) and highest (BMI > 30 kg/m2) BMI groups having significantly higher odds of engaging in UWCBs compared to the reference BMI group (18.5 ≤ BMI ≤ 24.9 kg/m2). CONCLUSIONS: The intention of weight management confounded the relationship between Body Mass Index (BMI) and the risk of UWCBs. These findings suggest that healthcare interventions for weight management behaviors should be tailored to adolescents with BMI ≥ 25 and BMI < 18.5.
This study looked at unhealthy weight control behaviors (UWCBs) in American teenagers, such as fasting, taking diet pills, or vomiting to control weight. These behaviors can lead to serious health problems, including eating disorders. The research analyzed data from over 100,000 teenagers between 1999 and 2013 to understand the connection between UWCBs and other risky behaviors like drinking alcohol, smoking, and attempting suicide. While previous research suggested that teens with higher body weight were more likely to engage in UWCBs, our findings showed a shift in this relationship after considering the teens' intentions to manage weight. Specifically, teens with very low body weight (BMI < 17) and a strong desire to lose weight had an increased risk of UWCBs. This highlights the need for healthcare providers to focus on the mental health and weight management goals of these teens to prevent harmful behaviors. Additionally, reconsidering the removal of UWCB-related questions from national surveys like YRBSS is important to continue monitoring these behaviors.
RESUMEN
Background: Walkable neighborhoods are closely related to an increase in walking frequency and the strengthening of social cohesion. These factors, in turn, contribute to lower BMI and other positive health-related outcomes. However, with a rapid increase in aging populations in China and the fact that women are facing more challenges than men as they age, especially mobility challenges because they tend to live longer leading to probabilities to become widowed. Nevertheless, less attention has been paid to understanding the gender difference between these relationships. Methods: Based on a survey of 533 older adults in Dalian, China, this study tried to investigate the intertwined relationship between perceived walkability, social cohesion, walking frequency, and BMI. A Structural Equation Model (SEM) and multiple-group analysis were applied to test the proposed framework. Results: First, results show that gender differences existed among the above interrelationships, and the most substantial gender gap was found in effects of social cohesion on BMI. Second, perceived walkability only has a direct effect (0.149) on walking frequencies for female seniors. Third, although the relationships between perceived walkability and BMI are not directly related in both male and female models, the indirect connection (-0.053) is substituted for female seniors. Besides, the inhibiting effect of walking on BMI, which is -0.511, is also valid for female seniors. Finally, in terms of the role of social cohesion, both the positive impacts of perceived walkability on it (0.225 for males and 0.325 for females) and its promoting effects on walking have been confirmed in male (0.142) and female models (0.103). The negative direct effect of social cohesion on BMI (-0.083) is only confirmed in male seniors. Conclusion: Insights derived from this analysis can help bring forward gender-specific interventions to build a more inclusive walkable and social environment to improve the mobility and physical health of older adults.

Background Drug-resistant tuberculosis is a major health issue around the world. The time it takes to find a sputum-positive patient is a major risk factor for the spread of tuberculosis, and many things can indicate a longer time to culture conversion. Also, there is strong proof that poor nutrition is linked to infectious diseases. So, this study aimed to look into the link between a person's body mass index (BMI) and the change of a sputum culture within three months in people who have rifampicin-resistant (RR)/multidrug-resistant (MDR)-tuberculosis (TB) kept on a bedaquiline-based regimen. Materials and methods The Department of Respiratory Medicine at King George's Medical University, Lucknow, hosted an observational, analytical, prospective, single-center study from May 2020 to April 2021. The study included 105 people who had been identified with RR/MDR-TB and were on an optimized background regimen that included a bedaquiline-based regimen. The result we were interested in was sputum culture conversion within three months, and we looked at how BMI related to that outcome. Analytical analyses utilized Pearson's chi-square test for categorical variables and the t-test for continuous variables. Differences with a P-value of <0.05 were considered significant. SPSS software (version 18.0, IBM Corp., Armonk, NY, USA) was used for all analyses, with missing data not replaced or credited. Results A total of 105 people who met the inclusion and exclusion criteria were analyzed. The patients had a mean age of 33.34 years and were mostly male 61 (58%). Fifty-eight (58; 55%) patients lived in rural areas. Most patients had fever 77 (73%), cough 72 (69%), and weight loss 66 (63%). Sixty-nine (69; 66%) patients had a history of TB. Fifty-seven patients had a BMI of <18.5 kg/m2, and 48 patients had with BMI of ≥18.5. At the end of the study, 75/105 patients converted their sputum culture. Of the 105 patients, 57 (54%) had a low BMI (less than 18.5 kg/m2). Among the 57 patients with a BMI of <18.5 kg/m2, only 28 (46%) achieved sputum culture conversion after 3 months while 29 (60%) of 48 with BMI ≥18.5 achieved sputum culture conversion after 3 months. Among the patients with a BMI <18.5, 15/57 (26%) tested positive for sputum culture after three months. In patients with a BMI of ≥18.5, only 4/48 (8%) patients tested positive for sputum culture after three months. Conclusion In patients with drug-resistant tuberculosis, low BMI (<18.5 kg/m2) was an independent risk factor for failing to convert sputum cultures within three months.
RESUMEN
BACKGROUND: Obesity rates have been increasing globally, leading to a higher incidence of knee osteoarthritis and a surge in primary and revision total knee arthroplasty (TKA). The debate continues on the impact of obesity on TKA success, particularly regarding the use of stemmed tibial components in obese patients. This systematic review aimed to compare the effectiveness of stemmed tibial components versus standard keeled tibial components in obese patients undergoing TKA, hypothesizing that stemmed components would yield better clinical and radiological outcomes. METHODS: A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines. Databases including PubMed, Embase, Scopus, and Web of Science were searched from inception to December 2023. The eligibility criteria were based on the PICO framework; Participants: Patients who have obesity undergoing TKA, Intervention: stemmed TKA, Comparator: standard keeled tibial TKA, Outcome: aseptic loosening, Patient-Reported Outcome Measures (PROMs), and overall revision. Data extraction and quality assessment were performed using the Newcastle-Ottawa Scale for cohort studies and the Cochrane risk-of-bias tool for randomized trials. RESULTS: The search yielded 470 studies, with 10 studies (42,533 knees) meeting the inclusion criteria. These studies included three randomized clinical trials and seven retrospective cohorts. The primary outcomes measured were aseptic loosening and overall revision rates, while secondary outcomes included PROMs. Results indicated mixed findings, with some studies suggesting improved outcomes with stemmed components in cases of aseptic loosening and mechanical failure, while others showed no significant difference. The PROMs did not show a significant difference between groups post-TKA. The certainty of the evidence was graded as "very low" using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) framework. CONCLUSION: Current literature does not provide conclusive evidence to support the routine use of stemmed tibial components in TKA for obese patients. The decision to use stem extensions should not solely rely on the patient's obesity status. Further high-quality studies are needed to clarify the role of stemmed components in TKA for this patient population.
RESUMEN
Introduction Weight stigma (WS), characterized by discrimination and stereotyping based on a person's weight, remains understudied in Saudi Arabia despite the country's high obesity rates. Particularly, limited research has been conducted on WS in Madinah. Understanding the factors contributing to WS in this region is crucial for developing targeted interventions to effectively address it. Hence, this study aimed to explore the effects of sociodemographic characteristics and body mass index (BMI) on WS among adults with obesity in Madinah. Methods Individuals with obesity who were seeking care at primary healthcare centers were included in this study. This research was an analytical cross-sectional study; Madinah City was divided into four areas. One primary health center from each area was randomly selected. Subsequently, a consecutive sampling technique was used to collect questionnaires from participants during the period of December 2023 to March 2024. The participants completed a self-administered electronic questionnaire, which included the Arabic-translated and validated version of the Weight Self-Stigma Questionnaire (WSSQ). Data analysis included descriptive, simple logistic regression and multiple logistic regression with forward stepwise analysis. Results A total of 383 participants completed the questionnaire, of which 225 (58.7%) were men and 158 (41.3%) were women. The analysis showed that individuals without a family history of obesity experienced higher WS levels than those with a family history [adjusted odds ratio (AOR) = 1.853, 95% confidence interval (CI): 1.010-2.844]. Moreover, individuals with obesity demonstrated the lowest WS levels than those without obesity (AOR = 0.027, 95% CI: 0.009-0.08). These findings provide insights into the association among sociodemographic factors, BMI, and WS in adults with obesity residing in Madinah, Saudi Arabia. Conclusion This study provides evidence that WS is a complex issue that is not solely determined by an individual's obesity status; rather, it is influenced by a lack of family history of obesity, which establishes the impact of social factors on WS. Therefore, comprehending the role of family dynamics and societal norms in shaping an individual's weight status is crucial in managing WS.
RESUMEN
Introduction Preterm prelabor rupture of membrane (PPROM) contributes to increasing rates of preterm birth, causing greater health risks for newborns. While the mechanisms driving PPROM are not well understood, one hypothesis is that it is due to systemic inflammation, which can be caused by obesity defined as a BMI [Formula: see text]30 kg/m2. The specific aim of the study was to compare neonatal outcomes after PPROM between patients who were obese vs not obese in early pregnancy at a tertiary medical center serving an Appalachian population. Methods An observational, descriptive retrospective review was conducted of the medical records of patients who were diagnosed with PPROM from January 2017 through December 2020. Patients with a single gestation at the time of PPROM without evidence of clinical infection requiring immediate delivery were included. Maternal characteristics, latency management, and birth outcomes were compared between obese ([Formula: see text]30 BMI) and non-obese (<30 BMI) patients. Results Of the 214 women in the study, 129 (60.3%) were obese pre-pregnancy and 85 (39.7%) were not. Most PPROM occurred between 32 and 36 weeks of gestation (145 patients, 67.8%), with 19.2% occurring at 26-31 weeks (41 patients), and 13.2% at <26 weeks of gestation (28 patients). Latency, defined as the days between PPROM and delivery, ranged from 0 to 80 days with a mean of 4.9 + 10.9 days. At least one day of latency was achieved for most patients (144/214; 67.3%). When outcomes were compared between obese and nonobese patients, the obese patients experienced significantly more complications (10.1% vs 2.4%; p=0.031), which were accompanied by greater neonatal morbidity 67 of 129 ((51.9%) vs 30 of 85 (35.3%); p=0.018). Obese women had greater odds that their newborns would experience neonatal morbidity than nonobese women (odds ratio, 1.98; 95% confidence interval, 1.1-3.5). Conclusion This study of Appalachian women found that pre-pregnancy BMI [Formula: see text]30 increased the risk of complications and neonatal morbidity after PPROM. To improve birth outcomes, healthcare workers and policymakers must work together to decrease rates of obesity in Appalachian women at or near childbearing age.
RESUMEN
AIM: To determine the correlation between body mass index (BMI), bone mineral density (BMD), and residual ridge resorption (RRR) in postmenopausal females and the effect of osteoporosis on RRR. MATERIALS AND METHODS: A study was conducted with 60 postmenopausal female individuals. BMI was calculated using the weight and height of the patient using a formula. BMD was assessed and graded using a T-score. RRR was determined using the Tallgren method. RESULTS: Most individuals showed a higher BMI (63.33%), which is in the overweight or obese category. BMD was lower in approximately 68.33% of patients, and RRR was significantly higher in about 60% of total patients. CONCLUSION: The higher the BMI values, the lesser the BMD and the higher the RRR.
RESUMEN
BACKGROUND: The global rise in obesity and related health complications has cast a spotlight on the urgent need for initiatives that promote informed dietary decisions. This cross-sectional study investigates the knowledge, attitudes, and practices of university students at Jazan University, Saudi Arabia, regarding menu calorie labeling. The study examines how these variables may affect dietary decisions, body mass index (BMI), and support for proposed legislative measures requiring calorie disclosure on restaurant menus. METHODS: The study included 581 Saudi university students who were 18 years of age or older as a convenience sample. A three-part questionnaire that asked about demographics, anthropometric measurements, and attitudes and behaviors related to calorie counting was completed by the participants. Using the Statistical Product and Service Solutions (SPSS, version 25.0; IBM SPSS Statistics for Windows, Armonk, NY) program, chi-square, t-tests, and ANOVA tests were used to evaluate the data. Both informed consent and ethical approval were obtained. RESULTS: The study finds that, even while more than half of the participants knew their recommended daily calorie intake and exhibited curiosity about calorie information on menus, this knowledge did not always result in healthy eating habits. Participants' opinions and behaviors regarding calorie labeling were significantly correlated with their BMI levels, indicating the importance of education in promoting nutritional awareness and healthy eating habits. New calorie labeling regulations received higher approval from people who regularly ate out. CONCLUSION: This study emphasizes the necessity of comprehensive nutritional education initiatives to raise calorie knowledge and encourage Saudi Arabian university students to make healthier eating choices. It also emphasizes the possible effects of legislative measures requiring calorie information on menus, particularly among regular diners. However, while evaluating the results, it is important to take into account the study's limitations, including self-reported data and convenience sample. To support menu calorie labeling legislation and inform targeted public health interventions for university students' eating behaviors, more research that takes cultural quirks and regional settings into account is necessary.
RESUMEN
OBJECTIVE: To investigate the effect of body mass index (BMI) on progesterone (P) level on trigger day in gonadotropin-releasing hormone antagonist (GnRH-ant) cycles. METHODS: This study was a retrospective cohort study. From October 2017 to April 2022, 412 in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) patients who were treated with GnRH-ant protocol for controlled ovarian hyperstimulation (COH) in the reproductive center of our hospital were selected as the research objects. Patients were divided into three groups according to BMI level: normal weight group (n = 230):18.5 kg/m2≤BMI < 24 kg/m2; overweight group (n = 122): 24 kg/m2≤BMI < 28 kg/m2; Obesity group (n = 60): BMI ≥ 28 kg/m2. Variables with p < .10 in univariate analysis (BMI, basal FSH, basal P, FSH days, Gn starting dose and E2 level on trigger day) and variables that may affect P level on trigger day (infertility factors, basal LH, total FSH, HMG days and total HMG) were included in the multivariate logistic regression model to analyze the effect of BMI on P level on trigger day of GnRH-ant protocol. RESULTS: After adjustment for confounding factors, compared with that in normal weight patients, the risk of serum P elevation on trigger day was significantly lower in overweight and obese patients (OR = 0.434 and 0.199, respectively, p < .05). CONCLUSION: The risk of P elevation on trigger day in GnRH-ant cycles decreased with the increase of BMI, and BMI could be used as one of the predictors of P level on trigger day in GnRH-ant cycles.

Background: There is inconsistent evidence regarding obesity's effect on surgical outcomes following retroperitoneal laparoscopic adrenalectomy (RLA). This study aimed to investigate the influence of obesity on surgical outcomes in patients undergoing RLA, with an emphasis on operative time, drainage tube removal time, postoperative hospital stays and perioperative complications. Methods: In this retrospective, single-center, observational study, all consecutive cases of unilateral RLA for adrenal disease from January 2012 to December 2021 were incorporated. The patients were divided into two groups based on their body mass index (BMI) of 28 kg/m2. To mitigate selection bias, propensity score matching (PSM) was conducted, using logistic regression to calculate propensity scores for balancing baseline characteristics. A multivariate logistic regression analysis was performed to assess how obesity affects operative time and intraoperative blood loss as well. The linear correlation between BMI and surgical outcomes, including prolonged operative time and increased intraoperative blood loss, was also examined using restricted cubic spline (RCS) analysis. Results: A total of 569 patients who underwent RLA were included. After PSM, 122 patients were apportioned to each group. Statistically significant differences were observed between the obese and non-obese group in operative time (97.5 vs. 115 min, P<0.001). There were no statistically significant differences between the two groups regarding hospital stay (6.7 vs. 6.8 days, P=0.58), drainage tube removal time (3.0 vs. 3.0 days, P=0.19), nor postoperative complications (9.0% vs. 12.3%, P=0.41). Furthermore, univariate logistic regression analysis revealed that, obese patients undergoing RLA were linked to prolonged operative time and increased intraoperative blood loss. After adjusting for potential confounders, the obese group showed a 67% increased risk of prolonged operative time and a 69% increased intraoperative blood loss. The RCS analysis revealed that BMI had a linear relationship with operative time (P for nonlinearity =0.47) and blood loss during surgery (P for linearity =0.89). Conclusions: In patients undergoing RLA, obesity exerts a significant influence on surgical outcomes, particularly with regard to operative time and intraoperative blood loss, as shown in multivariable logistic regression analysis and PSM to balance baseline characteristics.
RESUMEN
Background: Patients with multiple sclerosis (MS) have many potential factors (disease duration, spasticity, immobilization, or glucocorticoid use) that can deteriorate their nutritional status and impact both the progression and prognosis of the disease. Body mass index (BMI), the most widely used nutritional status assessment tool, has important limitations because it does not provide any data on body composition. Aim: This study aimed to assess the interrelationship between nutritional status assessment by both body mass index (BMI) and body composition using bioelectrical impedance analysis (BIA) and the consistency of diagnosis for underweight/underfat, normal weight/healthy, overweight/overfat, and obesity/obese MS patients. Methods: Anthropometric [BMI and waist-to-height ratio (WHtR)] and body composition (BIA) data were evaluated in 176 patients with MS. Patients were categorized into four nutritional status subgroups (underweight, normal weight, overweight, obese according to BMI, and underfat, healthy, overfat, and obese according to fat mass% by BIA). The median Expanded Disability Status Scale score was 4.5. Patients were then divided according to EDSS score as mild (EDSS 1.0-4.0) or moderate (EDSS 4.5-6.5) disability subgroups. Results: Based on BIA assessment, there was a significantly higher prevalence of overfat than of overweight based on BMI [n = 50 (28.41%) vs. n = 38 (21.59%); p < 0.05]. However, the prevalence of obesity did not differ significantly regardless of the mode of diagnosis and was not significantly lower when assessed using BIA [n = 26 (14.77%) vs. n = 30 (17.05%), respectively]. The overall compatibility rates (CR) of diagnoses made using both BMI and BIA were 75.6, 77.0, and 70.1% for all patients with MS and the mild and moderate subgroups, respectively. The lowest CR was observed in the overweight group. Adiposity significantly underestimated BMI in all subgroups. In the moderate MS subgroup, BMI significantly overcategorized patients with MS as having a normal weight (p < 0.05). Stratification for abdominal obesity (WHtR > 0.5) showed that BMI significantly underestimated the prevalence of MS in overweight and obese vs. overfat and obese patients, as assessed using BIA (60.5 vs. 67%; p < 0.05). Clinical status (EDSS and ΔEDSS) was more closely related to the nutritional status categorized by FAT% assessed using BIA than using BMI cutoff points. However, the relationship was not statistically significant. Conclusion: Using the BMI cutoff point for nutritional status assessment in patients with MS is associated with a significant underestimation of excess fat mass. BIA-based FAT% based on BIA have a better relationship with abdominal obesity and disability status than with BMI in patients with MS. The highest rate of false-negative diagnoses was based on the BMI in patients with MS and moderate disability. Adiposity assessment using BIA appears to be a useful method for proper nutritional status assessment in the patients group.
RESUMEN
OBJECTIVE: This study investigates the association of Body Mass Index (BMI) and age of epilepsy onset, in patients with epilepsy associated with temporal encephaloceles (TEs). METHODS: A comprehensive PubMed literature review was conducted using the keywords "temporal encephaloceles" and "epilepsy" for identifying articles for the analysis. Inclusion criteria encompassed all evidence levels reporting patients with TE-related epilepsy and documented BMI. Logistic regression analyses were performed to examine the effect of BMI on predicting epilepsy onset after the 25th year of age. Spearman's correlation assessed the relationship between BMI with epilepsy onset. Finally, the association between BMI and postsurgical outcomes, distinguishing between more favourable outcomes (Engel Class I and II) and less favourable outcomes (Engell Class III and IV) was explored. RESULTS: Of the initially identified 88 articles, nine were included in the analysis, involving 127 patients with TE-related epilepsy and reported BMI. The mean age of epilepsy onset was 24.9 years (SD = 14.8 years), with a mean BMI of 28.0 kg/m2 (SD = 7.4 kg/m2). A significant positive correlation was observed between BMI and age of epilepsy onset (rho = 0.448, p < 0.001). Female patients had higher BMI compared to male patients (30.1 kg/m2, SD = 8.7 kg/m2 and 26.5 kg/m2, SD = 5.3 kg/m2 respectively, p = 0.008). However, the epilepsy onset did not differ significantly between male and female patients (p = 0.26). The bivariate logistic regression showed that patients with increased BMI were more likely to have an epilepsy onset after the 25th year of age, adjusted for the confounder sex (OR = 1.133, 95%-CI [1.060, 1.211], p < 0.001). Finally, a potential trend indicated a higher average BMI among patients with more favourable postsurgical outcomes than less favourable postsurgical outcomes (27.3 kg/m2, SD = 7.7 kg/m2 and 24.8 kg/m2, SD = 2.2 kg/m2 respectively, p = 0.076).
RESUMEN
BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is the most popular bariatric surgery procedure in China. However, its cost-effectiveness in Chinese patients is currently unknown. OBJECTIVES: This study aims to assess the cost-effectiveness of LSG vs no surgery in Chinese patients with severe and complex obesity, taking into account both healthcare expenses and the potential improvement in health-related quality of life (HRQoL). METHODS: A retrospective cohort study was conducted, encompassing 135 Chinese patients who underwent LSG between January 3, 2022 and December 29, 2022, at a major bariatric center. The study evaluated the cost-effectiveness from a healthcare service perspective, employing the incremental cost-effectiveness ratio (ICER) for quality-adjusted life years (QALYs) gained. The analyses compared LSG with the alternative of not undergoing surgery over a 1-year period, using actual data, and extended to a lifetime horizon by projecting costs and utilities at an annual discount rate of 3.0%. Subgroup analyses were undertaken to explore cost-effectiveness variations across different sex, age and BMI categories, and diabetes status, employing a one-way analysis of variance (ANOVA). To ensure the reliability of the findings, one-way and probabilistic sensitivity analyses were executed. RESULTS: The results indicated that 1-year post-LSG, patients achieved an average total weight loss (TWL) of (32.7 ± 7.3)% and an excess weight loss (EWL) of (97.8 ± 23.1)%. The ICER for LSG compared to no surgery over a lifetime was $4,327/QALY, significantly below the willingness-to-pay (WTP) threshold for Chinese patients with severe and complex obesity. From a lifetime perspective, LSG proved to be cost-effective for all sex and age groups, across all BMI categories, and for both patients with and without diabetes. Notably, it was more cost-effective for younger patients, patients with higher BMI, and patients with diabetes. CONCLUSIONS: LSG is a highly cost-effective intervention for managing obesity in Chinese patients, delivering substantial benefits in terms of HRQoL improvement at a low cost. Its cost-effectiveness is particularly pronounced among younger individuals, those with higher BMI, and patients with diabetes.

To this date, COVID-19 remains an unresolved pandemic, and the impairment of redox homeostasis dictates the severity of clinical outcomes. Here we examined initial UCLA cohort of 440 COVID-19 patients hospitalized between March 1st and April 1st, 2020, representing the first wave of the pandemic. The mean age was 58.88 ± 21.12, among which males were significantly more than females (55.5 % vs. 44.5 %), most distinctively in age group of 50-69. The age groups of 50-69 (33.6 %) and ≥70 (34.8 %) dominated. The racial composition was in general agreement with Census data with slight under-representation of Hispanics and Asians, and over-representation of Caucasians. Smoking was a significant factor (28.8 % vs. 11.0 % in LA population), likewise for obesity (BMI ≥30) (37.4 % vs. 27.7 % in LA population). Patients suffering from obesity or BMI<18.5 checked into ICU at a significantly higher rate. A 74.5 % of the patients had comorbidities including diabetes, chronic kidney disease, chronic pulmonary disease, congestive heart failure and peripheral vascular disease. The levels of d-dimer were drastically upregulated (1159.5 ng/mL), indicating hypercoagulative state. Upregulated LDH (328 IU/L) indicated significant tissue damages. A distorted redox hemeostasis is a common trait associated with these risk factors and clinical markers. A quarter of the patients received antivirals, among which Remdesivir most prescribed (23.6 %). Majority received antithrombotics (75 %), and antibiotics. Upon admission, 67 patients were intubated or received CPR; 177 patients eventually received intensive care (40.2 %). While 290 were discharged alive, 10 remained hospitalized, 73 were transferred, and 36 died with 3 palliatively discharged. In summary, our data fully characterized a Californian cohort of COVID-19 at the breaking phase of the pandemic, indicating that population demographics, biophysical characters, comorbidities and molecular pathological parameters have significant impacts on the evolvement of a pandemic. These provide critical insights into effective management of COVID-19, and future break from another pathogen.

Background: About 10-20% of pancreas allografts are still lost in the early postoperative period despite the identification of numerous detrimental risk factors that correlate with graft thrombosis. Methods: We conducted a multicenter study including 899 pancreas transplant recipients between 2000 and 2018. Early pancreas failure due to complete thrombosis, long-term pancreas, kidney and patient survivals were analyzed and adjusted to donor, recipient and perioperative variables using a multivariate cause-specific Cox model stratified to transplant centers. Results: Pancreas from donors with history of hypertension (6.7%), as well as with high body mass index (BMI), were independently associated with an increased risk of pancreas failure within the first 30 post-operative days (respectively, HR= 2.57, 95% CI from 1.35 to 4.89 and HR= 1.11, 95% CI from 1.04 to 1.19). Interaction term between hypertension and BMI was negative. Donor hypertension also impacted long-term pancreas survival (HR= 1.88, 95% CI from 1.13 to 3.12). However, when pancreas survival was calculated after the postoperative day 30, donor hypertension was no longer a significant risk factor (HR= 1.22, 95% CI from 0.47 to 3.15). A lower pancreas survival was observed in patients receiving a pancreas from a hypertensive donor without RAAS (Renin Angiotensin Aldosterone System) blockers compared to others (50% vs 14%, p < 0.001). Pancreas survival was similar among non-hypertensive donors and hypertensive ones under RAAS blockers. Conclusion: Donor hypertension was a significant and independent risk factor of pancreas failure. The well-known pathogenic role of renin-angiotensin-aldosterone system seems to be involved in the genesis of this immediate graft failure.
