Worldwide trends in underweight and obesity from 1990 to 2022: a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults
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

Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey
Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10 years; 78.2% included were male with a median age of 37 years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020

Determining the Relative Susceptibility of Four Prion Protein Genotypes to Atypical Scrapie
Atypical
scrapie is a sheep prion (PrP<sup>Sc</sup>) disease whose
epidemiology is consistent with a sporadic origin and is associated
with specific polymorphisms of the normal cellular prion protein (PrP<sup>C</sup>). To determine the relative amounts of PrP polymorphisms
present in atypical scrapie, total PrP was digested with chymotrypsin
to generate characteristic peptides spanning relevant polymorphisms
at positions 136, 141, 154, 171, and 172 of sheep PrP<sup>C</sup>.
A multiple reaction monitoring method (MRM), employing <sup>15</sup>N-labeled internal standards, was used to detect and quantify these
polymorphisms present in both the PrP<sup>Sc</sup> and PrP<sup>C</sup> from heterozygous (ALRRY and ALHQY or ALRQD or AFRQY) atypical scrapie-infected
or uninfected control sheep. Both polymorphisms of the full length
and truncated (C1) natively expressed PrP<sup>C</sup> are produced
in equal amounts. The overall amount of PrP<sup>C</sup> present in
the infected or uninfected animals was similar. PrP<sup>Sc</sup> isolated
from heterozygotes was composed of significant amounts of both PrP
polymorphisms, including the ALRRY polymorphism which is highly resistant
to classical scrapie. Thus, an atypical scrapie infection does not
result from an overexpression of sheep PrP<sup>C</sup>. The replication
of all atypical scrapie prions occurs at comparable rates, despite
polymorphisms at positions 141, 154, 171, or 172
Iodine, a Mild Reagent for the Aromatization of Terpenoids

the dehydrogenation of testosterone
Quantitating PrP Polymorphisms Present in Prions from Heterozygous Scrapie-Infected Sheep
Scrapie
is a prion (PrP<sup>Sc</sup>) disease of sheep. The incubation
period of sheep scrapie is strongly influenced by polymorphisms at
positions 136, 154, and 171 of a sheep’s normal cellular prion
protein (PrP<sup>C</sup>). Chymotrypsin was used to digest sheep recombinant
PrP to identify a set of characteristic peptides [M<sub>132</sub>LGS<b><u>X</u></b>MSRPL<sub>141</sub> (<b><u>X</u></b> = A or V), Y<sub>153</sub><b><u>X</u></b>ENMY<sub>158</sub> (<b><u>X</u></b>,=
H or R), and Y<sub>166</sub>RPVD<b><u>X</u></b>Y<sub>172</sub> (<b><u>X</u></b> = H, K, Q,
or R)] that could be used to detect and quantitate polymorphisms at
positions 136, 154, and 171 of sheep PrP<sup>C</sup> or PrP<sup>Sc</sup>. These peptides were used to develop a multiple reaction monitoring
method (MRM) to detect the amounts of a particular polymorphism in
a sample of PrP<sup>Sc</sup> isolated from sheep heterozygous for
their PrP<sup>C</sup> proteins. The limit of detection for these peptides
was less than 50 attomole. Spinal cord tissue from heterozygous (ARQ/VRQ
or ARH/ARQ) scrapie-infected Rasa Aragonesa sheep was analyzed using
this MRM method. Both sets of heterozygotes show the presence of both
polymorphisms in PrP<sup>Sc</sup>. This was true for samples containing
both proteinase K (PK)-sensitive and PK-resistant PrP<sup>Sc</sup> and samples containing only the PK-resistant PrP<sup>Sc</sup>. These
results show that heterozygous animals contain PrP<sup>Sc</sup> that
is composed of significant amounts of both PrP polymorphisms
