INTRODUCTION:
Women continue to be underrepresented in academic anesthesiology. This study assessed guidelines in anesthesia journals over the past 5 years, evaluating differences in woman-led versus man-led guidelines in terms of author gender, quality, and changes over time. We hypothesized that anesthesia guidelines would be predominately man-led, and that there would be differences in quality between woman-led versus man-led guidelines.

METHODS:
All clinical practice guidelines published in the top 10 anesthesia journals were identified as per Clarivate Analytics Impact Factor between 2016 and 2020. Fifty-one guidelines were included for author, gender, and quality analysis using the Appraisal of Guidelines for Research & Evaluation (AGREE) II instrument. Each guideline was assessed across 6 domains and 23 items and given an overall score, overall quality score, and overall rating/recommendation. Stratified and trend analyses were performed for woman-led versus man-led guidelines.

RESULTS:
Fifty out of 51 guidelines were included: 1 was excluded due to unidentifiable first-author gender. In total, 255 of 1052 (24%) authors were women, and woman-led guidelines (woman-first author) represented 12 of 50 (24%) overall guidelines. Eighteen percent (9 of 50) of guidelines had all-male authors, and a majority (26 of 50, 52%) had less than one-third of female authors. The overall number and percentage of woman-led guidelines did not change over time. There was a significantly higher percentage of female authors in woman-led versus man-led guidelines, median 39% vs 20% (P = .012), as well as a significantly higher number of female coauthors in guidelines that were woman-led median 3.5 vs 1.0, P = .049. For quality, there was no significant difference in the overall rating or objective quality of woman- versus man-led guidelines. However, there was a significant increase in the overall rating of all the guidelines over time (P = .010), driven by the increase in overall rating among man-led guidelines, P = .002. The overall score of guidelines did not increase over time; however, they increased in man-led but not woman-led guidelines. There was no significant correlation between the percentage of female authors per guideline and either overall score or overall rating.

CONCLUSIONS:
There is a substantial disparity in the number of women leading and contributing to guidelines which has not improved over time. Woman-led guidelines included more women and a higher percentage of women. There was no difference in quality of guidelines by first-author gender or percentage of female authors. Further systematic and quota-driven sponsorship is needed to promote gender equity, diversity, and inclusion in anesthesia guidelines.

ABSTRACT

Purpose
Cardiorespiratory fitness (CRF) is a critical marker of overall health and a key predictor of morbidity and mortality, but the existing prediction equations for CRF are primarily derived from general populations and may not be suitable for patients with obesity.

Methods
Predicted CRF from different non-exercise prediction equations was compared with measured CRF of patients with obesity who underwent maximal cardiopulmonary exercise testing (CPET). Multiple linear regression was used to develop a population-specific nonexercise CRF prediction model for treadmill exercise including age, sex, weight, height, and physical activity level as determinants.

Results
Six hundred sixty patients underwent CPET during the study period. Within the entire cohort, R
2 values had a range of 0.24 to 0.46. Predicted CRF was statistically different from measured CRF for 19 of the 21 included equations. Only 50% of patients were correctly classified into the measured CRF categories according to predicted CRF. A multiple model for CRF prediction (mL·min−1) was generated (R
2 = 0.78) and validated using two cross-validation methods.

Conclusions
Most used equations provide inaccurate estimates of CRF in patients with obesity, particularly in cases of severe obesity and low CRF. Therefore, a new prediction equation was developed and validated specifically for patients with obesity, offering a more precise tool for clinical CPET interpretation and risk stratification in this population.

ABSTRACT

Purpose
Chronic, high-altitude hypoxic exposure increases the risk of high-altitude pulmonary hypertension (PH). Emerging evidence shows maternal exercise may improve offspring resistance to disease throughout life. The purpose of this study is to determine if maternal exercise mitigates chronic hypoxic-induced changes in the offspring indicative of high-altitude PH development.

Methods
Female adult C57BL/6J mice were randomly allocated to nonexercise or exercise conditions. Exercise consisted of voluntary running wheel exercise for 4 wk during the perinatal period. Three days after birth, the pups remained at low altitude (normoxia) or were exposed to hypobaric hypoxia of 450 mm Hg to simulate ~4500 m of altitude exposure until 8 wk of age. The study consisted of four groups: hypoxia + nonexercise pregnancy, hypoxia + exercise, or the respective normoxia conditions (normoxia + nonexercise or normoxia + exercise). Offspring body size, motor function, right ventricular systolic pressure (RVSP), and cardiopulmonary morphology were assessed after 8 wk in normoxia or hypoxia.

Results
Both hypoxic groups had smaller body sizes, reduced motor function, increased hematocrit, RVSP, muscularization in medium-sized pulmonary arteries, as well as right ventricular hypertrophy and contractility compared with the normoxic groups (P < 0.05).

Conclusions
Chronic hypoxia simulating 4500 m attenuated growth, lowered motor function, and elicited PH development. Voluntary maternal exercise did not significantly decrease RVSP in the offspring, which aligned with a lack of effect to attenuate abnormal body size and cardiopulmonary development due to chronic hypoxia. These findings are preliminary in nature, and more powered studies through larger group sizes are required to generalize the results to the population.

Published: May 2024

ABSTRACT

Purpose
We investigated whether longitudinally assessed physical activity (PA) and adherence specifically to World Health Organization PA guidelines mitigate or moderate mortality risk regardless of genetic liability to cardiovascular disease (CVD). We also estimated the causality of the PA–mortality association.

Methods
The study used the older Finnish Twin Cohort with 4897 participants aged 33 to 60 yr (54.3% women). Genetic liability to coronary heart disease and systolic and diastolic blood pressure was estimated with polygenic risk scores (PRS) derived from the Pan-UK Biobank (N ≈ 400,000; >1,000,000 genetic variants). Leisure-time PA was assessed with validated and structured questionnaires three times during 1975 to 1990. The main effects of adherence to PA guidelines and the PRS × PA interactions were evaluated with Cox proportional hazards models against all-cause and CVD mortality. A cotwin control design with 180 monozygotic twin pairs discordant for meeting the guidelines was used for causal inference.

Results
During the 17.4-yr (mean) follow-up (85,136 person-years), 1195 participants died, with 389 CVD deaths. PRS (per 1 SD increase) were associated with a 17% to 24% higher CVD mortality risk but not with all-cause mortality except for the PRS for diastolic blood pressure. Adherence to PA guidelines did not show significant independent main effects or interactions with all-cause or CVD mortality. Twins whose activity levels adhered to PA guidelines over a 15-yr period did not have statistically significantly reduced mortality risk compared with their less active identical twin sibling. The findings were similar among high, intermediate, and low genetic risk levels for CVD.

Conclusions
The genetically informed Finnish Twin Cohort data could not confirm that adherence to PA guidelines either mitigates or moderates genetic CVD risk or causally reduces mortality risk.

Published: May 2024

Introduction
During the COVID-19 pandemic, a set of social measures were adopted for the preservation of business activity and the protection of workers. One of these measures was issuing the Temporary Disability (TD) for COVID-19 cases, close contacts, and especially vulnerable workers.

Objetive
This study analyzes whether the TD registry could be used as a complementary source to traditional epidemiological surveillance.

Methods
A longitudinal study of time series was carried out with a cross-correlation analysis of TD and COVID-19 cases reported to the National Epidemiological Surveillance Network (RENAVE). The analysis included six pandemic waves between 10/03/2020 and 31/12/2021 in Spain. Cross-correlation coefficients (r) were calculated using a time lag of -14 days.

Results
During the study period, 2,253,573 TD processes were recorded in Spain and 4,894,802 COVID-19 cases were reported to RENAVE. Significant positive correlations were observed at time lags of -7, -10, and -14, indicating that TD notification preceded RENAVE notification. In the first and sixth pandemic waves, TD notification preceded RENAVE by 12 and 7 days, respectively. Negative correlations between the two series were observed in the second and fourth waves, coinciding with a lower number of reported cases. In the third and fifth waves, TD notification also preceded RENAVE (lags -1, -5 and -14, -7, respectively).

Conclusions
The results confirm the usefulness of TD registry as a complementary system to traditional epidemiological surveillance in Spain, by detecting COVID-19 cases in the 7, 10, and 14 days prior. A better positive correlation is observed in waves where more cases were reported.
Transgender health objectives of training for adult Endocrinology and Metabolism programs: Outcomes of a modified-Delphi study
Authors: Ahmad Tehmina , Schreyer Leighton , Fung Raymond , Yu Catherine 
Published: May 2024

Background
Transgender people encounter significant barriers when seeking timely, high-quality healthcare, resulting in unmet medical needs with increased rates of diabetes, asthma, chronic obstructive pulmonary disease, and HIV. The paucity of postgraduate medical education to invest in standardization of transgender health training sustains these barriers, leaving physicians feeling unprepared and averse to provide transgender health care. Closing this education gap and improving transgender healthcare necessitates the development of consensus-built transgender health objectives of training (THOOT), particularly in Adult Endocrinology and Metabolism Residency programs.

Methods
We conducted a two-round modified-Delphi process involving a nationally representative panel of experts, including Adult Endocrinology and Metabolism program directors, physician content experts, residents, and transgender community members, to identify THOOT for inclusion in Canadian Endocrinology and Metabolism Residency programs. Participants used a 5-point Likert scale to assess THOOT importance for curricular inclusion, with opportunities for written feedback. Data was collected through Qualtrics and analyzed after each round.

Findings
In the first Delphi round, panelists reviewed and rated 81 literature extracted THOOT, achieving consensus on all objectives. Following panelists’ feedback, 5 THOOT were added, 9 removed, 34 consolidated into 12 objectives, and 47 were rephrased or retained. In the second Delphi round, panelists assessed 55 THOOT. Consensus was established for 8 THOOT. Program directors’ post-Delphi feedback further consolidated objectives to arrive at 4 THOOT for curriculum inclusion.

Conclusions
To our knowledge, this is the first time a consensus-based approach has been used to establish THOOT for any subspecialty postgraduate medicine program across Canada or the United States. Our results lay the foundation towards health equity and social justice in transgender health medical education, offering a blueprint for future innovations.
Identification of ligand and receptor interactions in CKD and MASH through the integration of single cell and spatial transcriptomics
Authors: Moreno Jaime , Gluud Lise Lotte , Galsgaard Elisabeth D. , Hvid Henning , Mazzoni Gianluca , Das Vivek 
Published: May 2024

Background
Chronic Kidney Disease (CKD) and Metabolic dysfunction-associated steatohepatitis (MASH) are metabolic fibroinflammatory diseases. Combining single-cell (scRNAseq) and spatial transcriptomics (ST) could give unprecedented molecular disease understanding at single-cell resolution. A more comprehensive analysis of the cell-specific ligand-receptor (L-R) interactions could provide pivotal information about signaling pathways in CKD and MASH. To achieve this, we created an integrative analysis framework in CKD and MASH from two available human cohorts.

Results
The analytical framework identified L-R pairs involved in cellular crosstalk in CKD and MASH. Interactions between cell types identified using scRNAseq data were validated by checking the spatial co-presence using the ST data and the co-expression of the communicating targets. Multiple L-R protein pairs identified are known key players in CKD and MASH, while others are novel potential targets previously observed only in animal models.

Conclusion
Our study highlights the importance of integrating different modalities of transcriptomic data for a better understanding of the molecular mechanisms. The combination of single-cell resolution from scRNAseq data, combined with tissue slide investigations and visualization of cell-cell interactions obtained through ST, paves the way for the identification of future potential therapeutic targets and developing effective therapies.
Perinatal mortality after Chornobyl in contaminated regions of Ukraine
Authors: Körblein Alfred 
Published: May 2024

Background
Belarus and Ukraine were the countries most affected by the consequences of the Chornobyl nuclear power plant in 1986. A study of perinatal mortality in Belarus found a highly statistically significant increase in the 1990s in the most contaminated oblast Gomel but no increase during this period in the rest of Belarus. As a possible mechanism to interpret this increase as a late Chornobyl effect, it has been suggested that strontium-90 contained in Chornobyl fallout, incorporated during menarche, impairs the immune system of pregnant women which in turn increases perinatal mortality. In the present study, this hypothesis is tested using data from Ukraine.

Methods
Annual data on perinatal mortality, in the period 1981–2006 were provided by the Ministry of Public Health of Ukraine. Trends in perinatal mortality rates in the most contaminated regions of Ukraine (Kyiv and Zhytomyr oblasts and the city of Kyiv; study region) were compared with rates in the rest of Ukraine (control region). To identify any differences in perinatal mortality trends between the study and control regions, the ratios of perinatal mortality rates in the study region to the rates in the control region were analyzed using the calculated strontium concentration as a predictor.

Results
A trend analysis of perinatal mortality rates in Ukraine revealed two bell-shaped deviations from a long-term exponential trend with maxima at the beginning and end of the 1990s. The same pattern was found in the data from the study and control regions, but the deviations were almost three times higher in the study region than in the control region. An analysis of the ratios of perinatal mortality rates in the study region to the rates in the control region (odds ratios) showed an increase and decrease during the 1990s which was approximated by a lognormal density distribution. The calculated strontium concentration, when used as a predictor, also fitted the data well. Thus, the data from Ukraine confirms the results from Belarus. The analysis of the odds ratios revealed about 1000 excess perinatal deaths in the study region in the period 1990–2004. The corresponding figure for Ukraine as a whole was estimated at 3500 perinatal deaths.

Conclusion
It is hypothesized that the observed increase in perinatal mortality in the 1990s may be a late effect of incorporated strontium-90 on the immune system of pregnant women. The analysis is based on a theoretical model, as no data on strontium concentrations were available; the results should therefore be interpreted with caution. An updated study for Belarus would be desirable to corroborate the results.
Factors associated with oral health care behavior of people with type 2 diabetes mellitus: A hospital-based, cross-sectional study
Authors: Sairat Kamonchanok , Phoosuwan Nitikorn 
Published: May 2024

Background
Oral healthcare behavior determines oral health status and the incidence of oral diseases. People with type 2 diabetes mellitus (T2DM) are at-risk of having low oral healthcare behavior and disease-related oral health.

Objective
To investigate the oral health status and factors associated with oral healthcare behavior among people with T2DM in Thailand.

Methods
In total, 401 people with T2DM participated in the study based on their attendance at a non-communicable disease clinic at sub-district health promotion hospitals in Bueng Kan, a north-eastern province in Thailand. A structured questionnaire was used to obtain variables of interest. Linear regression analysis at the 95% confidence interval (CI) was applied.

Results
The majority of participants were female (73.8%). More than three-quarters had more than 20 permanent teeth (77.6%), a decay missing filling tooth index was 10.6 teeth/person. Many participants had four permanent occlusal pairs (69.6%), had tooth decay (74.6%), and some participants had tooth filling (32.2%). Statistically significant factors associated with oral healthcare behavior were: having complications associated with diabetes mellitus (Beta = -0.097, 95%CI = -1.653, -0.046), oral health literacy (Beta = 0.119, 95%CI = 0.009, 0.150), educational level (Beta = 0.123, 95%CI = 0.103, 0.949), oral healthcare attitude (Beta = 0.258, 95%CI = 0.143, 0.333), and oral health services (Beta = 0.430, 95%CI = 0.298, 1.408).

Conclusions
People with T2DM had good oral health status. People with T2DM with low oral health literacy, low attitude, and low level of oral health services were at a higher risk of poor oral healthcare behavior.
Combined effects of low pressure superheated steam drying and vacuum drying on sugar reduction and quality attribute in mango (Mangifera indica L.) slices

Published: May 2024

Abstract
Consumers paying more attention to physical health has led to an increasing market demand for low-sugar dried fruit products. The quality of products dried via low pressure superheated steam drying (LPSSD) is not only superior to those dried via conventional hot air or vacuum drying (VD), but also has the potential to reduce sugar content. In order to elucidate the mechanism of reducing the sugar of mango slices by LPSSD and obtain low-sugar dried mango slices, the combined effect of LPSSD–VD on mango slices was studied and an evaporation experiment of a sugar solution in a low pressure superheated steam environment was performed. This study revealed that the sugar reduction of mango slices was mainly due to the superheated steam carryover phenomenon in the second half of the constant-temperature stage and the occurrence of Maillard reaction during LPSSD. The quality attributes of mango slices dried using LPSSD–VD was improved compared with LPSSD and VD. As a result, LPSSD–VD could be used to regulate the sugar content in dried fruit and provide a theoretical basis for the production of low-sugar preserved fruits.
Two new Zn(ii) coordination polymers incorporating 2-(2,6-dichlorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline: Synthesis and structure

Published: May 2024

Abstract
Based on phenanthroline derivate ligand and Zn(ii), two novel coordination polymers, namely [Zn(L)(hta)]
n
(1) and {[Zn2(L)2(dhb)2]·H2O}
n
(2) (L = 2-(2,6-dichlorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline, H2hta = heptanedioic acid, and H2dhb = 3,5-dinitro-2-hydroxybenzoic acid), have been synthesized under the hydrothermal condition. For 1, each hta anion bridges two Zn(ii) atoms in a tridentate mode to shape into a chain structure and through different π–π stacking interactions to form a three-dimensional supramolecular structure. The L ligand of 2 connects two neighbouring Zn(ii) atoms to give a 1D chain, which is further extended into the 2D supramolecular layer.
Stress deletion or stress demotion? An acoustic study of stress in Spanish lexical compounds
Authors: Lin Dongmei , Piñeros Carlos-Eduardo 
Published: May 2024

Abstract
In Spanish lexical compounds, stress on the final constituent is consistently preserved; however, it is uncertain whether stress on the initial constituent is preserved as well. Some linguists claim that stress is deleted from the initial constituent, whereas a few argue, instead, that it is demoted from primary to secondary. Given that empirical evidence has been scarce, this issue remains unresolved. To inform the debate, the present study examines all known phonetic correlates of stress in both accented and unaccented contexts. The acoustic measures of lexical compounds are compared to those of non-compound words and phrases that have a similar segmental structure. The results demonstrate that the initial constituent of lexical compounds bears secondary stress. This secondary stress, as a result of stress demotion, differs from rhetorical secondary stress both phonetically and phonologically. These findings provide fresh insights into the definitional properties as well as the prosodic structure of Spanish compounds.
