Direct costs for outpatient excess body weight treatment in Brazilian children and adolescents attending a public children's hospital

Abstract Objective: To estimate the direct costs of treating excess body weight in children and adolescents attending a public children's hospital. Methods: This study analyzed the costs of the disease within the Brazilian Unified Health System (SUS) for 2,221 patients with excess body weight using a microcosting approach. The costs included operational expenses, consultations, and laboratory and imaging tests obtained from medical records for the period from 2009 to 2019. Healthcare expenses were obtained from the Table of Procedures, Medications, Orthoses/Prostheses, and Special Materials of SUS and from the hospital's finance department. Results: Medical consultations accounted for 50.6% (R$703,503.00) of the total cost (R $1,388,449.40) of treatment over the period investigated. The cost of treating excess body weight was 11.8 times higher for children aged 5-18 years compared to children aged 2-5 years over the same period. Additionally, the cost of treating obesity was approximately 4.0 and 6.3 times higher than the cost of treating overweight children aged 2-5 and 5-18 years, respectively. Conclusion: The average annual cost of treating excess body weight was R$138,845.00. Weight status and age influenced the cost of treating this disease, with higher costs being observed for individuals with obesity and children over 5 years of age. Additionally, the important deficit in reimbursement by SUS and the small number of other health professionals highlight the need for restructuring this treatment model to ensure its effectiveness, including a substantial increase in government investment.

Association between intake of flavanones and the overweight/obesity and central obesity in children and adolescents: a cross-sectional study from the NHANES database.

Aim: The prevalence of obesity (Ob), overweight (Ow) and central obesity (CO) in children and adolescents has increased dramatically over the past decades globally. Flavanones have been recently studied as adjuvants for the treatment of obesity. This study was aimed at evaluating the association between intake of flavanones and its subclasses and the Ow/Ob and CO in children and adolescents. Methods: This cross-sectional study extracted the data of children and adolescents with Ow/Ob and CO from the National Health and Nutrition Examination Survey (NHANES) database for 2007-2010 and 2017-2018. Ow and Ob were defined as a body mass index (BMI) ≥ 85th percentile. CO was defined as a waist circumference (WC) ≥ 90th percentile. The association between intake of flavanones and its subclasses and the Ow/Ob and CO in children and adolescents was determined by weighted univariate and multivariate Logistic regression models adjusted for potential covariates, and odds ratios (ORs) with 95% confidence intervals (CIs) was calculated. To further explore association between intake of flavanones and its subclasses and the Ow/Ob and CO in children and adolescents, subgroup analyses stratified by age, and gender. Results: Of the total 5,970 children and adolescents, 2,463 (41.2%) developed Ow/Ob and 1,294 (21.7%) patients developed CO. High intake of flavanones, eriodictyol, hesperetin, and naringenin were associated with lower odds of Ow/Ob in children and adolescents. (OR: 0.75, 95%CI: 0.62-0.92, OR: 0.69, 95%CI: 0.55-0.87, OR: 0.69, 95%CI: 0.55-0.87, and OR: 0.76, 95%CI: 0.63-0.92, respectively). In addition, high intake of flavanones, eriodictyol, and naringenin were associated with lower odds of CO in children and adolescents (OR: 0.71, 95%CI: 0.57-0.88, OR: 0.67, 95%CI: 0.51-0.86, and OR: 0.69, 95%CI: 0.55-0.86, respectively). Subgroup analyses showed that among all the different subgroups, high intake of flavanones was associated with lower odds of Ow/Ob and CO in children and adolescents. Conclusion: A diet loaded with high flavanones were associated with lower odds of Ow/Ob and CO in children and adolescents, and children and adolescents should be encouraged to increase their intake of flavanones.

Carotid Intima-Media Thickness, Overweight, and Poor Sleep Quality in Commercial Airline Pilots: A Cross-Sectional Study.

Background Cardiovascular disease is a leading cause of premature career termination in commercial airline pilots (APs). In this cross-sectional study, we sought to investigate the relationship between intima-media thickness (IMT), a marker of subclinical atherosclerosis, and cardiovascular risk factors in APs, focusing on overweight status and sleep quality. Methods A total of 140 male APs were categorized into four groups based on body mass index (BMI) and Pittsburgh Sleep Quality Index (PSQI) score: overweight poor sleepers (OW-PS), overweight good sleepers (OW-GS), normal weight poor sleepers (NW-PS), and normal weight good sleepers (NW-GS). IMT was quantified in the common carotid artery (CCA) and carotid bulb using ultrasound, yielding a composite IMT (IMTcom) measure. Common cardiovascular risk factors were assessed in all participants. Results The prevalence of overweight and poor sleep quality was 43.6% and 32.9%, respectively. The OW-PS group had significantly higher age, heart rate, total cholesterol, and low-density lipoprotein (LDL) cholesterol compared to other groups (p<0.05). Overweight pilots, regardless of sleep quality, had increased IMTcom compared to normal-weight pilots (p<0.001). Age and LDL cholesterol were independent predictors of IMTcom in the OW-PS and OW-GS groups (p<0.05). Conclusions Overweight status, irrespective of sleep quality, is associated with increased IMT in APs, suggesting a higher burden of subclinical atherosclerosis. Interventions focused on reducing LDL cholesterol levels and managing age-related cardiovascular risk factors could be advantageous in mitigating the risk of atherosclerotic vascular disease in overweight pilots.

The association between excess weight and COVID-19 outcomes: An umbrella review.

This umbrella review assessed the association between excess weight and COVID-19 outcomes. MEDLINE, PsycINFO, and CINAHL were systematically searched for reviews that assessed the association between excess weight and COVID-19 outcomes. A second-order meta-analysis was conducted on the available data for intensive care unit admission, invasive mechanical ventilation administration, disease severity, hospitalization, and mortality. The quality of included reviews was assessed using the AMSTAR-2 appraisal tool. In total, 52 systematic reviews were included, 49 of which included meta-analyses. The risk of severe outcomes (OR = 1.86; 95% CI: 1.70 to 2.05), intensive care unit admission (OR = 1.58; 95% CI: 1.45 to 1.72), invasive mechanical ventilation administration (OR = 1.70; 95% CI: 1.57 to 1.83), hospitalization (OR = 1.82; 95% CI: 1.61 to 2.05), and mortality (OR = 1.35; 95% CI: 1.24 to 1.48) following COVID-19 infection was significantly higher in individuals living with excess weight compared with those with a healthy weight. There was limited evidence available in the included reviews regarding the influence of moderating factors such as ethnicity, and the majority of included reviews were of poor quality. Obesity appears to represent an important modifiable pre-infection risk factor for severe COVID-19 outcomes, including death.

Home environment factors associated with child BMI changes during COVID-19 pandemic.

BACKGROUND: The influence of home obesogenic environments, as assessed by the validated Family Nutrition and Physical Activity (FNPA) tool, and child obesity during the COVID pandemic were evaluated using electronic health records in this retrospective cohort study. METHODS: Historical data on BMI and the FNPA screening tool were obtained from annual well-child visits within the Geisinger Health System. The study examined youth ages 2-17 that had a BMI record and an FNPA assessment prior to the pandemic (BMI 3/1/19-2/29/20), 1 BMI record 3 months into the pandemic (6/1/20-12/31/20) and 1 BMI in the second year of the pandemic (1/1/21-12/31/21). Tertiles of obesity risk by FNPA score were examined. Mixed-effects linear regression was used to examine change in BMI slope (kg/m2 per month) pre-pandemic to pandemic using FNPA summary and subscales scores as predictors and adjusting for confounding factors. RESULTS: The analyses included 6,746 children (males: 51.7%, non-Hispanic white: 86.6%, overweight:14.8%, obesity:10.3%, severe obesity: 3.9%; mean(SD) age: 5.7(2.8) years). The rate of BMI change in BMI was greatest from early pandemic compared to pre-pandemic for children in lowest versus highest tertiles of FNPA summary score (0.079 vs. 0.044 kg/m2), FNPA-Eating (0.068 vs. 0.049 kg/m2), and FNPA-Activity (0.078 vs. 0.052 kg/m2). FNPA summary score was significantly associated with change in BMI from the pre-pandemic to early pandemic period (p = 0.014), but not associated with change in BMI during the later pandemic period. CONCLUSIONS: This study provides additional insight into the changes in the rate of BMI change observed among children and adolescents in the United States during the COVID-19 pandemic. The FNPA provides ample opportunity to continue our exploration of the negative impact of the COVID-19 pandemic on the longitudinal growth patterns among children and adolescents.

Novel Guided Self-Help for the treatment of Binge Eating Disorder: Feasibility, Acceptability, and Preliminary Efficacy.

Purpose: Binge eating disorder (BED) is a prevalent eating disorder. Many individuals with BED do not receive evidence-based care due to many barriers. This preliminary study evaluated the feasibility, acceptability, and potential efficacy of a manualized guided self-help (GSH) intervention with support in the form of a culturally adapted manual for a French-Canadian population.Method: Twenty-two women with overweight or obesity meeting the BED diagnostic criteria participated in an 8-week open trial. The GSH programme combined a self-help book and weekly support phone calls. Participants were assessed at baseline, at week 4, postintervention, and 12 weeks following its end. Feasibility was measured by attrition rates, participation, and satisfaction. Acceptability was measured by a questionnaire based on the Theoretical Framework of Acceptability. Potential efficacy outcomes were objective binge eating days, eating disorder symptomatology, depressive symptoms, and propensity to eat intuitively.Results: The GSH programme has proven feasible (4.5% attrition, 91% completion, 95.5% satisfaction) and acceptable. Potential efficacy results showed promising improvements on all outcomes (19% abstinence, 70.9% reduction in objective binge eating days).Conclusion: Although preliminary, this programme warrants further study as it may be an efficient and cost-effective way to deliver GSH for BED patients with accessibility barriers.

Body composition, metabolic syndrome, and lifestyle in treatment-naïve gender-diverse youth in Israel.

BACKGROUND: There is a scarcity of published studies evaluating transgender/gender-diverse youth before initiating gender-affirming hormones. AIM: To study the body composition, metabolic syndrome (MetS) components and lifestyle habits in treatment-naïve transgender youth. METHODS: Cross-sectional study evaluating 153 transgender youth [median age 15.7 years, 94 transgender males] who attended The Israeli Children and Adolescents Gender Clinic between 6/2021-12/2022. Clinical, metabolic data and lifestyle habits (diet, physical activity and sleep patterns) were retrieved from the medical files. Body composition was determined by bioelectrical impedance analysis. Body mass index and muscle-to-fat ratio z-scores were calculated by sex designated at birth. RESULTS: Weight categories differed between genders, with a greater proportion of subjects classified as underweight among transgender females, and a greater proportion affected by overweight/obese/severe obese among transgender males (p = 0.035). The odds for MetS components were increased by 2.2 for every 1 standard deviation decrease in the muscle-to-fat ratio z-score (95%CI: 1.45 to 3.26, p < 0.001). About one-third of the cohort did not meet any of the three lifestyle recommendations. Transgender males had increased odds for MetS components by 3.49 (95%CI: 1.63 to 7.44, p = 0.001). CONCLUSIONS: Treatment-naïve transgender-male adolescents have an imbalance between muscle and adipose tissue, which places them at increased susceptibility for MetS components even prior to hormonal treatment.

Association of obesity and overweight with the risk of preeclampsia in pregnant women: an observational cohort study.

BACKGROUND: According to the World Health Organization, obesity is considered a pervasive global epidemic with significant medical and social implications. In antenatal mothers, the prevalence varies from 40% in Western countries to 12% in India which leads to life-threatening complications-preeclampsia and eclampsia. AIM: This study delves into the association between body mass index (BMI) and preeclampsia, among primi antenatal mothers with pregnancy-induced hypertension (PIH). METHODS: An observational cohort (prospective) study was conducted among 150 primi antenatal mothers with pregnancy-induced hypertension in Government Headquarters Hospital, Tamil Nadu, India. Demographic data, body mass index, and pregnancy outcomes were assessed. Statistical analysis was performed using the SPSS 28.0 version. RESULTS: Among 150 pregnant women, 63 (42%) were overweight, and 13 (8.7%) were obese. Higher BMI was significantly associated with maternal complications, especially preeclampsia (P < 0.001). Moreover, other complications such as abruptio placenta, pulmonary edema, eclampsia, and postpartum hemorrhage were not significantly associated with BMI. CONCLUSION: The study calls attention to the persistent link between BMI and preeclampsia, emphasizing the need for comprehensive strategies aligned with the Sustainable Development Goal. Despite ongoing efforts, the study suggests a lack of substantial change in the prevalence of preeclampsia associated with increased BMI, prompting the exploration of innovative interventions to address weight-related factors during pregnancy for improved maternal and neonatal well-being.

Mindfulness-based eating awareness training versus itself plus implementation intention model: a randomized clinical trial.

BACKGROUND: Obesity causes many physical and mental illnesses. This study compares mindfulness-based eating awareness training (MB-EAT) versus MB-EAT plus implementation intention model for effectiveness on body mass index (BMI), weight self-efficacy, and physical activity in obese women with BMIs ≤ 25 (n = 52). METHODS: In this randomized clinical trial, the participants were selected by the simple random sampling method and randomly divided into three groups. A 12-session MB-EAT of 150 min per session was performed for experimental group I. The experimental group II received MB-EAT alone for physical activity planning and MB-EAT plus implementation intention; also, both groups were compared to the control group. Data were measured by the scales, a questionnaire, and a checklist, and the P-values are based on the results of the generalized estimating equation (GEE) test. P < 0.001 were considered the significance level. RESULTS: The MB-EAT and MB-EAT + implementation intention effectiveness on the two experimental groups' BMI, weight self-efficacy, and physical activity was significantly different from the control group. In the integrated group versus the MB-EAT group, BMI, physical activity, and physical discomfort, were more effective than the weight self-efficacy subscales. Both intervention groups were effective on BMI, weight self-efficacy, and physical activity, but the integrated group's effectiveness was more. CONCLUSIONS: The MB-EAT effectiveness trial is theory-based, reducing weight and the psychological and behavioral consequences of overweight and obese adults. The MB-EAT + the Implementation intention model is to plan regular and daily exercise according to each individual's specific circumstances. TRIAL REGISTRATION: The trial registration number: (IRCT20200919048767N1).

The effects of non-soy legumes consumption on serum levels of inflammatory biomarkers and Adiponectin in overweight/obese adults: A systematic review and meta-analysis of Randomized Controlled Trials.

OBJECTIVES: Non-soy legumes offer many health benefits, including improved arterial function, reduced cholesterol levels, and better management of cardiovascular diseases and type 2 diabetes. This systematic review and meta-analysis aim to clarify the inconclusive findings from randomized controlled trials (RCTs) by comprehensively evaluating the effects of non-soy legumes consumption on serum levels of inflammatory biomarkers and Adiponectin. METHODS: The search encompassed databases up to January 2024, including PubMed, EMBASE, MEDLINE, Scopus, Web of Science, and Cochrane CENTRAL to retrieve all RCTs examining the effects of non-soy legumes on inflammatory biomarkers or Adiponectin. The effect sizes quantified as mean differences (MD) and standard deviations (SD) of outcomes, and an overall effect estimate was derived using a random-effects model. RESULTS: RCTs examining serum levels of C-reactive protein (CRP), Interleukin-6 (IL-6), Tumor Necrosis Factor-alpha (TNF-α), Interleukin-1ß (IL-1ß), and Adiponectin were included in the final meta-analysis. Results revealed that consumption of non-soy legumes increased Adiponectin serum levels (p = 0.0017) and reduced IL-1ß serum levels (p < 0.0001). However, it may not significantly affect CRP (p = 0.2951), IL-6 (p = 0.2286), and TNF-α (p = 0.6661) levels. Subgroup analyses showed that non-soy legumes consumption significantly decreased TNF-α serum levels in studies involving healthy participants. Additionally, sensitivity analysis using the leave-one-out method suggested a potential significant reduction in serum levels of IL-6. CONCLUSIONS: This study indicates that consuming non-soy legumes can increase levels of Adiponectin and decrease serum levels of IL-1ß in overweight or obese adults.

Impact of Resistance and Endurance Training on Ghrelin and Plasma Leptin Levels in Overweight and Obese Subjects.

Exercise training is a valuable tool for improving body weight and composition in overweight or obese adults, which leads to a negative energy balance. It is relevant to consider whether exercise can help people lose weight or prevent weight gain because any energy expended in exercise increases the severity of hunger and promotes food consumption. Over the past decade, the identification of the circulating peptide ghrelin, which alerts the brain to the body's nutritional state, has significantly expanded our understanding of this homeostatic mechanism that controls appetite and body weight. To shed more light on this issue, we decided to investigate the effects of resistance and endurance training on plasma ghrelin and leptin levels. In addition, we sought to understand the mechanisms by which acute and chronic exercise can regulate hunger. This review analyzes studies published in the last fifteen years that focused on changes suffered by ghrelin, leptin, or both after physical exercise in overweight or obese individuals. Most studies have shown a decrease in leptin levels and an increase in ghrelin levels in these cases. Exercise regimens that support weight maintenance need further investigation.

Exploring the Multifaceted Influences on Childhood Nutritional Status: A Study Conducted in South Punjab, Pakistan.

Introduction The double burden of malnutrition (DBM) in Pakistan is a rising concern affecting school-going children, marked by coexisting under- and over-nutrition within the same population. Key influences include shifts in dietary habits, socioeconomic status, and lifestyle changes due to rapid urbanization. With a focus on Multan, Pakistan, the study seeks to assess the proportion of underweight and overweight students while identifying the risk factors and sociodemographic characteristics associated with this incidence. The aim is to guide future health interventions addressing this multidimensional health challenge. Materials and methods This study, adopting a descriptive cross-sectional research design, collected data from female teenage students through interviews and anthropometric measurements. A total of 300 participants were randomly selected from a comprehensive school list representing diverse urban and rural settings. Participants' weight and height were measured to calculate their body mass index (BMI), categorizing them into underweight, normal weight, and overweight groups. The relevant risk factors were collected through an interview questionnaire. Collected data were analyzed using IBM SPSS Statistics for Windows, Version 26.0 (Released 2019; IBM Corp., Armonk, New York, United States), with the results stratified according to socioeconomic, dietary, and psychosocial factors and compared across different weight categories. Results The study collected data from 300 students, revealing a correlation between socioeconomic status, dietary habits, and BMI. Parental occupation significantly affected nutritional status, with children of laborers primarily falling within normal and underweight categories. Dietary habits like frequency of fast food and milk or dairy consumption showed notable associations with nutritional status. Psychosocial factors such as peer or teacher comments about weight and outdoor sports participation also influenced the students' nutritional status. However, factors like family income, video game hours, and the presence of pets at home did not show significant associations with nutritional status. Conclusions The study illustrates a multi-faceted association between socioeconomic status, dietary habits, and BMI among schoolchildren in Multan, Pakistan, emphasizing the need for comprehensive interventions.

A cross-sectional study of medial longitudinal arch development in children with different BMI.

Introduction: The influence of excess weight on the development of children's feet remains a subject of debate. To further elucidate whether this relation occurs, this study compared arch morphology and flexibility in three groups of children: underweight, normal, and overweight. Methods: In total, 1,532 children (807 boys, 725 girls; age range 7-11 years) participated in the study. The researchers measured the participants' height and weight, calculated their body mass index, and categorized their weight status as underweight, normal weight, or overweight. A three-dimensional foot model was taken using a three-dimensional plantar scanner under non-weight-bearing and weight-bearing conditions to obtain arch morphometric indices (arch index and arch volume) and arch flexibility index (arch volume index). Results: Analysis of the data showed that the arch index was higher in overweight children compared to underweight and normal weight children (p < 0.05), but the differences in arch volume and arch volume index in overweight children compared to underweight and normal weight children were not statistically significant (p > 0.05). All children were divided into flatfoot, normal, and pes cavus groups according to arch index, and the arch volume index was statistically significant (p < 0.01). Conclusions: Overweight was not absolutely associated with arch structure and arch flexibility in children from a three-dimensional perspective. Arch development is a long-term process, and it is not clear whether being overweight has an effect on soft tissue or bone formation. Future studies will focus on the effects of long-term overweight on foot structure and arch flexibility in children.

Very-low-calorie diet-based intensive lifestyle intervention for remission of type 2 diabetes: Real-world experience in a South Asian population.

AIMS: Very low-calorie diet (VLCD) can induce weight loss and diabetes remission (DR) amongst people with obesity and recent-onset type 2 diabetes (T2D). We aimed to determine the effectiveness and acceptability of VLCD in achieving DR amongst Sri Lankan adults with T2D. METHODS: A retrospective analysis was conducted in a diabetes practice where VLCD-based Diabetes Remission Programme (VDRP) was offered for adults (>18 years) with T2D for <3 years and body mass index over 25 kg/m2. VLCD (~800 kcal/day, provided with/without diet replacement formula) was offered for 8-12 weeks, followed by gradual food reintroduction and exercise. DR was defined as HbA1c <6.5% at least 3 months after stopping glucose-lowering medications. RESULTS: A total of 170 participants who enrolled in the VDRP (mean age 38.4 years [±11.1], men 68%, mean baseline HbA1c 86.9 [±18.1] mmol/mol (10.1 [±2.1]%), median duration of T2D 2 years [IQR 1-2]) and 87 (51%) of them followed the programme (attended at least one follow-up visit). Amongst the individuals who followed the VDRP, 40.2% achieved DR (35/87), compared with 2.4% (2/83) amongst those who did not follow the VDRP (aHR 9.3, 95% CI 2.2-16.4, p = 0.002). The proportion achieving normoglycaemia (HbA1c < 6.5%) but continued to take glucose-lowering medication was 20/87 among VDRP followers and 20/85 amongst VDRP non-followers. The commonest reasons for not following the VDRP were too restrictive dietary quantity (92%) and difficulties in finding recommended food items (67%). Majority (79%) would recommend VDRP to others. CONCLUSIONS: VDRP is effective in achieving T2D remission amongst Sri Lankan adults with recently diagnosed T2D and obesity. Over half of the participants followed the programme and over 75% would recommend it to others, indicating good acceptability.

Effects of an mHealth intervention on maternal and infant outcomes from pregnancy to early postpartum for women with overweight or obesity: A randomized controlled trial.

BACKGROUND: Women with overweight (OW) and those with obesity (OB) tend to gain excessive weight during pregnancy, often resulting in adverse outcomes. The long-term effects of mobile health (mHealth) interventions on maternal and infant outcomes remain unclear. AIMS: To examine the effects of an mHealth intervention on OW and OB from the course of their pregnancy to six months postpartum. METHODS: A randomized controlled trial was conducted in northern Taiwan. Ninety-two pregnant women with a body mass index (BMI)of ≥25 kg/m2 were recruited from prenatal clinics at <17 weeks of gestation. Prepregnancy weight was baseline maternal weight, with data collected subsequently at the last assessment before childbirth and six months postpartum. The intervention group (IG) received the mHealth intervention, while the control group (CG) received standard antenatal care. The trial was registered on ClinicalTrials.gov (identifier: NCT04553731) with the initial registration date of September 16, 2020. FINDINGS: The IG tended to have a lower mean body weight than the CG at the last assessment before childbirth (82.23 kg vs 84.35 kg) and at six months postpartum (72.55 Kg vs 72.58 Kg). IG's newborn birth weight was significantly lower than CG's (3074.8 vs. 3313.6 g; p = 0.009). Regression analysis revealed that OB in IG had a significant reduction in weight before childbirth (ß = -7.51, p = 0.005) compared to OB in CG. Compared to OW in CG, both OW in IG (ß = -243.59, p = 0.027) and OB in IG (ß = -324.59, p = 0.049) were associated with decreased newborn birth weight. CONCLUSIONS: mHealth helped women with obesity to successfully manage their GWG and body weight before childbirth and newborns' birth weight, despite this effect not persisting to reduce weight retention at six months postpartum.

Genetic polymorphisms (FTO rs9939609 and TMEM rs6548238), adipokines (leptin and adiponectin) and adiposity in children and adolescents with asthma.

OBJECTIVE: To describe independent factors related to the interaction of FTO rs9939609, TMEM18 rs6548238, leptin, and adiponectin in children/adolescents with asthma, under the influence of obesity. METHODS: The authors performed a cross-sectional study with 57 children/adolescents, ages 8-19 years, at a tertiary hospital, from 2017 to 2018. Participants were classified by nutritional status, performed spirometry with a bronchodilator test and completed an asthma questionnaire, higher scores indicated more asthma symptoms. Two asthma groups were formed: Group 1(G1)-normal-weight; Group 2(G2)-overweight/obese. Serum was collected for adipokines (n = 32) and genetic polymorphisms (n = 53) dosages. RESULTS: Age and body mass index (BMI) correlated directly in normal-weight (p = 0.009) and obese participants (p = 0.004). Girls reported more asthma complaints (p = 0.044). Participants with negative bronchodilator responses presented lower BMI (14.55-17.16) than responders (19.4-26.84) (p = 0.049). Leptin dosages are related directly to BMI (5,34-40 ng/ml in obese × 0,54-42 ng/ml in nonobese) (p = 0.003). Levels were high in girls (4.78-17.55 µg/ml) (p = 0.029) and low in nonobese boys (0.54-6.92 µg/ml) (p = 0.006). In obese, low leptin levels (< 10 ng/ml) were found in small airway dysfunction carriers (p = 0.025); elevated adiponectin (> 5 µg/ml) correlated with FEV1/FVC > 80 % (p = 0.035) and positive bronchodilator tests (8.84-13 µg/ml) (p = 0.039); and FTO A allele correlated with low adiponectin 0-8.84 µg/ml (p = 0.021) and low FEV1/FVC (46 %-88 %) (p = 0.023). CONCLUSION: BMI correlated directly with age and leptin levels. Obese participants presented high serum levels of leptin and FTO A allele correlated with low FEV1/FVC. Larger cohorts are necessary for better elucidation of the role of adipokines and polymorphisms in the pathophysiology of asthma and obesity.

Global research trends and hotspots in overweight/obese comorbid with depression among children and adolescents: A bibliometric analysis.

BACKGROUND: Overweight/obesity combined with depression among children and adolescents (ODCA) is a global concern. The bidirectional relationship between depression and overweight/obesity often leads to their comorbidity. Childhood and adolescence represent critical periods for physical and psychological development, during which the comorbidity of overweight/obesity and depression may increase the risk of adverse health outcomes. AIM: To evaluate the relationship between ODCA, we conduct a bibliometric analysis to aid in formulating prevention and treatment strategies. METHODS: From 2004 to 2023, articles related to ODCA were selected using the Science Citation Index Expanded from the Web of Science Core Collection. Bibliometric analysis of relevant publications, including countries/regions, institutions, authors, journals, references, and keywords, was conducted using the online bibliometric analysis platforms, CiteSpace, VOSviewer, and bibliometrix. RESULTS: Between 2004 and 2023, a total of 1573 articles were published on ODCA. The United States has made leading contributions in this field, with Harvard University emerging as the leading contributor in terms of research output, and Tanofsky being the most prolific author. The J Adolescent Health has shown significant activity in this domain. Based on the results of the keyword and reference analyses, inequality, adverse childhood experiences, and comorbidities have become hot topics in ODCA. Moreover, the impact of balanced-related behavior and exploration of the biological mechanisms, including the potential role of key adipocytokines and lipokines, as well as inflammation in ODCA, have emerged as frontier topics. CONCLUSION: The trend of a significant increase in ODCA publications is expected to continue. The research findings will contribute to elucidating the pathogenic mechanisms of ODCA and its prevention and treatment.

A retrospective analysis of haematological side effects of olaparib in excess-weight and normal BMI patients with ovarian cancer.

Background: Olaparib is the first poly(ADP-ribose) polymerase inhibitor approved in Europe for the treatment of platinum-sensitive patients with newly diagnosed or recurrent platinum-sensitive ovarian cancer with a confirmed BRCA mutation or homologous recombination deficiency (HRD). Epidemiological studies have shown an incompatible association between ovarian cancer and obesity, but there have also been scientific reports indicating that obesity, especially severe obesity, increases the risk of ovarian cancer. Olaparib has a wide range of side effects, especially anaemia and neutropenia, which may lead to dose reduction or therapy discontinuation. Therefore, therapeutic drug monitoring (TDM) is recommended. The aim of the study was a retrospective analysis of threshold value of the trough concentration of olaparib (Ctrough) and haematological adverse reactions after olaparib treatment (300 mg/12 h) in excess-weight and normal body mass index (BMI) patients with ovarian cancer. Materials and methods: The pilot study was conducted on 38 ovarian cancer patients who were divided into two groups: I - normal BMI patients (BMI = 18.5-24.9 kg/m2; n = 14), II - excess-weight patients, i.e. overweight and obese patients (BMI ≥ 25 kg/m2; n = 24). The severity of neutropenia and anaemia was graded according to the Common Terminology Criteria for Adverse Events (CTCAE v5.0). The values of the mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), and red blood cell distribution width (RDW) parameters were also taken into account. HPLC-UV method (λ = 254 nm) was applied to measure olaparib plasma concentrations. Results: There were no statistically significant differences in olaparib Ctrough between the groups - 1602.86 vs. 1567.40 ng/mL (p = 0.9156). However, the overweight and obese patients had slightly higher dose/kg-adjusted olaparib Ctrough - 204.17 vs. 159.32 ng/mL/mg/kg. The incidence of grade 1 anaemia in the groups was as follows: I - 42.86%, II - 41.67%. Grade 2 and 3 anaemia was observed only in group II - 4.17% and 8.33%, respectively. The incidence of neutropenia in the groups of patients was as follows: grade 1: group I - 21.43%, group II - 20.83%; grade 2: group I - 7.14%, group II - 4.17%. Conclusions: The incidence of haematological adverse reactions to olaparib, such as neutropenia and grade 1 anaemia in the group of overweight and obese patients was the same as in the normal BMI group. The overweight and obese patients were characterised by higher severity of haematological adverse reactions to olaparib and slightly higher dose/kg-adjusted olaparib Ctrough. After one month of treatment with olaparib the overweight and obese patients had significantly lower red blood cells (RBC) and haemoglobin (Hgb) levels than the patients with normal BMI, which may indicate that anaemia develops faster in this group of patients.

Prevalence and metabolic risk factors of chronic kidney disease among a Mexican adult population: a cross-sectional study in primary healthcare medical units.

Introduction: The intricate relationship between obesity and chronic kidney disease (CKD) progression underscores a significant public health challenge. Obesity is strongly linked to the onset of several health conditions, including arterial hypertension (AHTN), metabolic syndrome, diabetes, dyslipidemia, and hyperuricemia. Understanding the connection between CKD and obesity is crucial for addressing their complex interplay in public health strategies. Objective: This research aimed to determine the prevalence of CKD in a population with high obesity rates and evaluate the associated metabolic risk factors. Material and Methods: In this cross-sectional study conducted from January 2017 to December 2019 we included 3,901 participants of both sexes aged ≥20 years who were selected from primary healthcare medical units of the Mexican Social Security Institute (IMSS) in Michoacan, Mexico. We measured the participants' weight, height, systolic and diastolic blood pressure, glucose, creatinine, total cholesterol, triglycerides, HDL-c, LDL-c, and uric acid. We estimated the glomerular filtration rate using the Collaborative Chronic Kidney Disease Epidemiology (CKD-EPI) equation. Results: Among the population studied, 50.6% were women and 49.4% were men, with a mean age of 49 years (range: 23-90). The prevalence of CKD was 21.9%. Factors significantly associated with an increased risk of CKD included age ≥60 years (OR = 11.70, 95% CI [9.83-15.93]), overweight (OR = 4.19, 95% CI [2.88-6.11]), obesity (OR = 13.31, 95% CI [11.12-15.93]), abdominal obesity (OR = 9.25, 95% CI [7.13-11.99]), AHTN (OR = 20.63, 95% CI [17.02-25.02]), impaired fasting glucose (IFG) (OR = 2.73, 95% CI [2.31-3.23]), type 2 diabetes (T2D) (OR = 14.30, 95% CI [11.14-18.37]), total cholesterol (TC) ≥200 mg/dL (OR = 6.04, 95% CI [5.11-7.14]), triglycerides (TG) ≥150 mg/dL (OR = 5.63, 95% CI 4.76-6.66), HDL-c <40 mg/dL (OR = 4.458, 95% CI [3.74-5.31]), LDL-c ≥130 mg/dL (OR = 6.06, 95% CI [5.12-7.18]), and serum uric acid levels ≥6 mg/dL in women and ≥7 mg/dL in men (OR = 8.18, 95% CI [6.92-9.68]), (p < 0.0001). These factors independently contribute to the development of CKD. Conclusions: This study underscores the intricate relationship between obesity and CKD, revealing a high prevalence of CKD. Obesity, including overweight, abdominal obesity, AHTN, IFG, T2D, dyslipidemia, and hyperuricemia emerged as significant metabolic risk factors for CKD. Early identification of these risk factors is crucial for effective intervention strategies. Public health policies should integrate both pharmacological and non-pharmacological approaches to address obesity-related conditions and prevent kidney damage directly.
