    Background Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. Methods We used data from 3663 population-based studies with 222 million participants that measured height and weight in representative samples of the general population. We used a Bayesian hierarchical model to estimate trends in the prevalence of different BMI categories, separately for adults (age ≥20 years) and school-aged children and adolescents (age 5–19 years), from 1990 to 2022 for 200 countries and territories. For adults, we report the individual and combined prevalence of underweight (BMI <18·5 kg/m2) and obesity (BMI ≥30 kg/m2). For schoolaged children and adolescents, we report thinness (BMI <2 SD below the median of the WHO growth reference) and obesity (BMI >2 SD above the median). Findings From 1990 to 2022, the combined prevalence of underweight and obesity in adults decreased in 11 countries (6%) for women and 17 (9%) for men with a posterior probability of at least 0·80 that the observed changes were true decreases. The combined prevalence increased in 162 countries (81%) for women and 140 countries (70%) for men with a posterior probability of at least 0·80. In 2022, the combined prevalence of underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, and countries in the Middle East and north Africa. Obesity prevalence was higher than underweight with posterior probability of at least 0·80 in 177 countries (89%) for women and 145 (73%) for men in 2022, whereas the converse was true in 16 countries (8%) for women, and 39 (20%) for men. From 1990 to 2022, the combined prevalence of thinness and obesity decreased among girls in five countries (3%) and among boys in 15 countries (8%) with a posterior probability of at least 0·80, and increased among girls in 140 countries (70%) and boys in 137 countries (69%) with a posterior probability of at least 0·80. The countries with highest combined prevalence of thinness and obesity in school-aged children and adolescents in 2022 were in Polynesia and Micronesia and the Caribbean for both sexes, and Chile and Qatar for boys. Combined prevalence was also high in some countries in south Asia, such as India and Pakistan, where thinness remained prevalent despite having declined. In 2022, obesity in school-aged children and adolescents was more prevalent than thinness with a posterior probability of at least 0·80 among girls in 133 countries (67%) and boys in 125 countries (63%), whereas the converse was true in 35 countries (18%) and 42 countries (21%), respectively. In almost all countries for both adults and school-aged children and adolescents, the increases in double burden were driven by increases in obesity, and decreases in double burden by declining underweight or thinness. Interpretation The combined burden of underweight and obesity has increased in most countries, driven by an increase in obesity, while underweight and thinness remain prevalent in south Asia and parts of Africa. A healthy nutrition transition that enhances access to nutritious foods is needed to address the remaining burden of underweight while curbing and reversing the increase in obesit

    WOS: 000340163600008Flood hazard and arising risks due to associated vulnerabilities still appear to be among the common problems in today's hydrology in spite of highly motivated assessments and increasing knowledge and awareness as well as targeted measures for mitigation, preparedness, and emergency management. Beside the role of overall inaction, deficiencies in precautionary actions and presence of natural barriers and inaccurate or incomplete approaches in flood studies towards estimating flood magnitudes and frequencies are also assumed to have considerable impacts on limited control against the flood phenomenon. Prevalent claims about the invalidity of the stationarity assumption in hydrologic studies indicate any ignorance of nonstationarity as potential sources of ineffective flood assessments and the associated improper actions. The presented study investigates potential impacts and relative significance of observed trends on the magnitude and frequency of floods through comparisons performed over stationary and nonstationary flood frequency analyses. Results indicate slightly significant discrepancies between the estimates from both the stationary and nonstationary analyses by potentially pointing out to the arising needs for considering the nonstationarity in flood studies.

    ABSTRACTPurpose:To report and compare the surgical, visual, and anatomical outcomes following treatment of dislocated intraocular lenses (IOLs).Methods:The medical records of 28 eyes of 28 patients were evaluated. Age, gender, pre-and postoperative best-corrected visual acuity (BCVA), surgical methods, and complications were recorded.Results:Pre-and postoperative BCVA ranged from counting fingers to 20/32 and from counting fingers to 20/25, respectively. Late-onset dislocations were the most frequently observed complication. The most frequent surgical method was IOL repositioning in 15 of 28 patients, followed by IOL exchange in 11 patients, and IOL removal in 2 patients. Only 1 patient required surgical re-intervention with IOL capture.Conclusions:Visual acuity improved following the use of either IOL repositioning or IOL exchange. No superiority of one method over the other was observed. In the present retrospective case series, management of dislocated IOLs with repositioning or exchange of the primary implant conferred comparable surgical and visual outcomes

    Blood Pressure Variability in Fabry Disease Patients

    Introduction: Fabry disease is a rare metabolic, multisystemic, and X-linked lysosomal storage disorder. The involvement of the autonomic nervous system is well defined; however, data on the variability of the blood pressure (BP) and heart rate in Fabry disease are largely missing. In this study, we aimed to examine the circadian variations of BP and heart rate variability in Fabry disease patients. Methods: We recruited 31 consecutive adult (age >18 years) Fabry disease patients (16 males and 15 females) who were regularly followed up in our outpatient clinic between July 2019 and March 2020. We performed ambulatory blood pressure monitoring and echocardiography in all patients. We used standard deviation (SD), coefficient of variation (CV), and average real variability as the measures of variability. We constructed 2 control groups for propensity score matching using age, sex, and eGFR parameters in the first group and adding antihypertensive drug use to the above parameters in the second group. Results: All BP measurements were significantly lower in the FD group compared to that of the control groups, except the nighttime systolic BP. Regarding nondipping and reverse dipping statuses, FD patients and controls were similar. We found that none of the BP variability measures were higher in FD patients. Regarding heart rate variability data, both the nighttime SD and CV were significantly lower in FD patients compared to those of the controls. Conclusion: A decrease in heart rate variability, rather than an increase in BP variability, might be an early marker of autonomic involvement in FD

    Objectives. Increased platelet activation plays an important role in the development of atherosclerosis. Mean platelet volume (MPV) is a determinant of platelet activation. In our study, we aimed to determine whether MPV levels are elevated in non-dipper patients compared with dippers and healthy controls. In addition, we tried to find out if MPV levels are correlated with blood pressure measurements in hypertensive patients. Methods. This cross-sectional study included 56 hypertensive patients; 27 age- and sex-matched healthy volunteers were enrolled to study as a control subjects. Ambulatory blood pressure monitoring was performed for all patients. Hypertensive patients were divided into two groups: 28 dipper patients (10 male, mean age 51 +/- 8 years) and 28 non-dipper patients (11 male, mean age 53 +/- 10 years). MPV was measured in a blood sample collected in EDTA tubes and was also used for whole blood counts in all patients. Results. In non-dipper patients, 24-h systolic blood pressure (141.5 +/- 10.21 vs 132.3 +/- 7.7 mmHg, p < 0.001), 24-h diastolic blood pressure (88.2 +/- 8.5 vs 81.0 +/- 8.2 mmHg, p < 0.01) and 24-h average blood pressure (105.7 +/- 8.5 vs 97.7 +/- 7.4 mmHg, p < 0.001) are significantly higher than dippers. Whereas daytime measurements were similar between dippers and non-dippers, there was a significant difference between each group during night-time measurements (night-time systolic 137.1 +/- 11.0 vs 120.2 +/- 8.0 mmHg, p < 0.001; night-time diastolic 85.3 +/- 8.0 vs 72.8 +/- 7.9 mmHg, p < 0.001). Non-dipper patients (9.61 +/- 0.42 fl) demonstrated higher levels of MPV compared with dippers (9.24 +/- 0.35 fl) and normotensives (8.87 +/- 0.33 fl) (p < 0.001 and p < 0.001, respectively). There was significant correlation between MPV and ambulatory diastolic and systolic blood pressure in non-dipper hypertensives. Conclusion. Our results suggest that MPV, a determinant of platelet activation, has a positively correlation with blood pressure and elevated in non-dipper compared with dippers and controls. Increased platelet activation could contribute to increase the atherosclerotic risk in non-dipper patients compared with dippers
