RESUMEN

Surgical menopause causes a sharp drop in estrogen levels in middle-aged women, thus preventing the gradual physiological adaptation that is characteristic of the perimenopause. Previous studies suggest that surgical menopause might increase the risk of dementia later in life. In addition, the transition to motherhood entails long-lasting endocrine and neuronal adaptations. We compared differences in whole-brain cortical volume between women who reached menopause by surgery and a group of women who reached spontaneous non-surgical menopause and determined whether these cortical differences were influenced by previous childbearing. Using surface-based neuroimaging techniques, we investigated cortical volume differences in 201 middle-aged women (134 women who experienced non-surgical menopause, 78 of whom were parous women; and 67 women who experienced surgical menopause, 39 of whom were parous women). We found significant atrophy in the frontal and temporal regions in women who experienced surgical menopause. Nulliparous women with surgical menopause showed significant lower cortical volume in the left temporal gyrus extending to the medial temporal lobe cortex, as well as in the precuneus bilaterally compared to parous women with surgical menopause; whereas our results revealed no significant differences between parous women with surgical menopause and both parous and nulliparous women who reached a non-surgical menopause. Furthermore, in the surgical menopause group, we found a negative correlation between cortical volume and age at first pregnancy in the temporal lobe. Our study suggests that the long-term brain remodeling of parity may mitigate the neural impact of the sudden drop in estrogen levels that characterizes surgical menopause.

RESUMEN

Latinx gay, bisexual, and other men who have sex with men (LMSM) report lower pre-exposure prophylaxis (PrEP) use than their white, non-Latinx counterparts. We hypothesize that this disparity is partially attributable to social ecological factors that can be addressed via prevention interventions. In this retrospective study, we first examined data from 253 LMSM to determine whether theorized associations existed between acquisition of a PrEP prescription (uptake) in relation to several social ecological factors based on a conceptual framework of determinants of access to and uptake of PrEP for LMSM. We also explored relations between frequency of PrEP use (adherence) and social ecological factors with a subsample of 33 LMSM who had initiated PrEP 12 months prior to assessment. In this study, individual-level factors from this framework included age and socioeconomic status. Perceived access to medical care represented both individual- and community-level determinants of PrEP uptake and adherence. Interpersonal-level factors were social support and relationship status. Structural/cultural-level factors were sexual identity development status, the masculinity norm of heterosexual self-presentation, traditional Latinx masculine gender role beliefs of machismo and caballerismo, racial identity, and immigration status. Results indicated that older men and those who endorsed the synthesis/integration status of sexual identity development were more likely to acquire a PrEP prescription during their lifetime in comparison to peers. PrEP adherence was linked with being older, reporting higher socioeconomic status, reporting more appraisal social support, self-identifying as white-Latinx, being U.S.-born, and endorsing less sexual identity uncertainty and more heterosexual self-presentation. Results specify modifiable factors that may inform tailored, community-based prevention efforts to increase PrEP use and decrease existing HIV/AIDS disparities among LMSM.

RESUMEN

INTRODUCTION: This study explores how empowering human resource management (HRM) practices based on structural empowerment (access to opportunities, resources, support, and information) affect both personal initiative and job satisfaction of service employees through individual-level factors (psychological empowerment). METHODS: We conducted a cross-sectional survey study and collected 439 valid responses from service employees in Spain. The hypotheses were tested using structural equation modeling (SEM) with confidence intervals based on 10,000 resamples (i.e., bootstrapping technique). RESULTS: Our results showed that psychological empowerment partially mediated the relationship between structural empowerment and job satisfaction. It also fully mediated the relationship between structural empowerment and personal initiative at work. CONCLUSION: These findings emphasize the importance of HRM practices that can empower employees as key determinants of job satisfaction and personal initiative at service companies. Furthermore, a structural empowerment approach is a valid theoretical framework for studying and understanding employees' affective evaluations of work and, more specifically, their personal initiative.

RESUMEN

AIMS: Chronic obstructive pulmonary disease (COPD) is an important comorbidity in heart failure. The MIMO trial showed that patients with acute cardiogenic pulmonary edema (ACPE) treated with midazolam had fewer serious adverse events than those treated with morphine. In this post hoc analysis, we examined whether the presence/ absence of COPD modifies the reduced risk of midazolam over morphine. METHODS: Patients >18 years old clinically diagnosed with ACPE and with dyspnea and anxiety were randomized (1:1) at emergency department arrival to receive either intravenous midazolam or morphine. In this post hoc analysis, we calculated the relative risk (RR) of serious adverse events in patients with and without COPD. Calculating the CochranMantel-Haenszel interaction test, we evaluated if COPD modified the reduced risk of serious adverse events in the midazolam arm compared to morphine. RESULTS: Overall, 25 (22.5%) of the 111 patients randomized had a history of COPD. Patients with COPD were more commonly men with a history of previous episodes of heart failure, than participants without COPD. In the COPD group, the RR for the incidence of serious adverse events in the midazolam versus morphine arm was 0.36 (95%CI, 0.1-1.46). In the group without COPD, the RR was 0.44 (95%CI, 0.22-0.91). The presence of COPD did not modify the reduced risk of serious adverse events in the midazolam arm compared to morphine (p for interaction =0.79). CONCLUSIONS: The reduced risk of serious adverse events in the midazolam group compared with morphine is similar in patients with and without COPD.

RESUMEN

This paper presents results concerning mechanistic modeling to describe the dynamics and interactions between biomass growth, glucose consumption and ethanol production in batch culture fermentation by Kluyveromyces marxianus (K. marxianus). The mathematical model was formulated based on the biological assumptions underlying each variable and is given by a set of three coupled nonlinear first-order Ordinary Differential Equations. The model has ten parameters, and their values were fitted from the experimental data of 17 K. marxianus strains by means of a computational algorithm design in Matlab. The latter allowed us to determine that seven of these parameters share the same value among all the strains, while three parameters concerning biomass maximum growth rate, and ethanol production due to biomass and glucose had specific values for each strain. These values are presented with their corresponding standard error and 95% confidence interval. The goodness of fit of our system was evaluated both qualitatively by in silico experimentation and quantitative by means of the coefficient of determination and the Akaike Information Criterion. Results regarding the fitting capabilities were compared with the classic model given by the logistic, Pirt, and Luedeking-Piret Equations. Further, nonlinear theories were applied to investigate local and global dynamics of the system, the Localization of Compact Invariant Sets Method was applied to determine the so-called localizing domain, i.e., lower and upper bounds for each variable; whilst Lyapunov's stability theories allowed to establish sufficient conditions to ensure asymptotic stability in the nonnegative octant, i.e., R+,03. Finally, the predictive ability of our mechanistic model was explored through several numerical simulations with expected results according to microbiology literature on batch fermentation.

RESUMEN

We diagnosed 11 Guillain-Barré syndrome (GBS) cases among 71,904 COVID patients attended at 61 Spanish emergency departments (EDs) during the 2-month pandemic peak. The relative frequency of GBS among ED patients was higher in COVID (0.15‰) than non-COVID (0.02‰) patients (odds ratio [OR] = 6.30, 95% confidence interval [CI] = 3.18-12.5), as was the standardized incidence (9.44 and 0.69 cases/100,000 inhabitant-years, respectively, OR = 13.5, 95% CI = 9.87-18.4). Regarding clinical characteristics, olfactory-gustatory disorders were more frequent in COVID-GBS than non-COVID-GBS (OR = 27.59, 95% CI = 1.296-587) and COVID-non-GBS (OR = 7.875, 95% CI = 1.587-39.09) patients. Although COVID-GBS patients were more frequently admitted to intensive care, mortality was not increased versus control groups. Our results suggest SARS-CoV-2 could be another viral infection causing GBS. ANN NEUROL 2021;89:598-603.

RESUMEN

Dmanisi (Georgia) is one of the oldest Early Paleolithic sites discovered out of Africa. In addition, it is the best site to understand the first Homo deme out of Africa and the first hominin occupation of Central to Western Eurasia. It has produced more than 40 hominin remains, including several very informative skulls, found in direct association with faunal remains and numerous lithic artifacts. To date, fossil amphibians and reptiles are one of the few proxies that have been used to propose quantitative climate reconstructions for the time where the hominins were living at Dmanisi. The aim of the present study is to review and amplify the previous paleoclimatic interpretation given by Blain et al. (2014), with an enhanced methodology using geographic information system and based on uncertain distribution area-occupied distribution area discrimination technique. This procedure permits to approach to a more precise common species distribution area and then using the WorldClim v. 2.1 climate database to propose for the first time monthly reconstructions for temperature and rainfall, in addition to annual parameters. The same technique is used to infer dominant ecoregions through the study area and potential tree coverage. Dmanisi climate is newly reconstructed as warm and semi-arid, similar to the present-day Mediterranean climate. New estimates however suggest warmer temperatures than previously reconstructed, together with a slightly higher but much more irregular amount of rainfall. The aridity indexes suggest a six months dry period, from May to October. Associated regional paleoenvironment is mainly characterized by Mediterranean forests, woodlands, and scrub, and the potential tree coverage is around 25%, that is, much less forested than today. New estimates agree with the 'Iberian' hominin ecological model, and with other proxies (large mammals, small mammals and archaeobotanical remains) that indicate a period of increased aridity contemporaneous with human occupations of the site.

RESUMEN

OBJECTIVE: The authors investigated the incidence, risk factors, clinical characteristics, and outcomes of upper gastrointestinal bleeding (UGB) in patients with coronavirus disease 2019 (COVID-19), who were attending the emergency department (ED), before hospitalization. METHODS: We retrospectively reviewed all COVID-19 patients diagnosed with UGB in 62 Spanish EDs (20% of Spanish EDs, case group) during the first 2 months of the COVID-19 outbreak. We formed 2 control groups: COVID-19 patients without UGB (control group A) and non-COVID-19 patients with UGB (control group B). Fifty-three independent variables and 4 outcomes were compared between cases and controls. RESULTS: We identified 83 UGB in 74,814 patients with COVID-19 who were attending EDs (1.11%, 95% CI=0.88-1.38). This incidence was lower compared with non-COVID-19 patients [2474/1,388,879, 1.78%, 95% confidence interval (CI)=1.71-1.85; odds ratio (OR)=0.62; 95% CI=0.50-0.77]. Clinical characteristics associated with a higher risk of COVID-19 patients presenting with UGB were abdominal pain, vomiting, hematemesis, dyspnea, expectoration, melena, fever, cough, chest pain, and dysgeusia. Compared with non-COVID-19 patients with UGB, COVID-19 patients with UGB more frequently had fever, cough, expectoration, dyspnea, abdominal pain, diarrhea, interstitial lung infiltrates, and ground-glass lung opacities. They underwent fewer endoscopies in the ED (although diagnoses did not differ between cases and control group B) and less endoscopic treatment. After adjustment for age and sex, cases showed a higher in-hospital all-cause mortality than control group B (OR=2.05, 95% CI=1.09-3.86) but not control group A (OR=1.14, 95% CI=0.59-2.19) patients. CONCLUSIONS: The incidence of UGB in COVID-19 patients attending EDs was lower compared with non-COVID-19 patients. Digestive symptoms predominated over respiratory symptoms, and COVID-19 patients with UGB underwent fewer gastroscopies and endoscopic treatments than the general population with UGB. In-hospital mortality in COVID-19 patients with UGB was increased compared with non-COVID patients with UGB, but not compared with the remaining COVID-19 patients.

RESUMEN

BACKGROUND: The main purpose was to evaluate the changes in peripapillary retinal nerve fiber layer (RNFL) thickness and vessel density (VD) in post-COVID-19 patients during 12-month follow-up. METHODS: In this prospective study, patients with COVID-19 who were attended in the Hospital Clinico San Carlos (Madrid, Spain) were included. All patients underwent a complete ophthalmological examination, optic nerve head optical coherence tomography (OCT), and OCT angiography (OCTA) using the Cirrus HD-OCT 5,000 with AngioPlex OCTA 1, 3, and 12 months after laboratory-confirmed diagnosis. Sociodemographic data, medical history, disease severity, and laboratory workup were registered. RESULTS: A total of 180 eyes of 90 patients with SARS-CoV-2 infection were included; the mean age was 55.5 ± 8.9 years, and 46 patients (51%) were females. The mean visual acuity was 0.76 ± 0.16, and no abnormalities attributable to SARS-CoV-2 were detected in the ocular or fundus examination. No differences in the OCT and OCTA data were found between severity groups in each visit (all P > 0.05). Overall, there was a decrease in RNFL global thickness ( P < 0.001) from the first to the last visit, and an increase in VD and flux index was noted in some sectors at the 12-month examination. A significant correlation was detected at 12 months between vascularization parameters and RNFL thickness. CONCLUSIONS: One year after SARS-CoV-2 infection, changes in peripapillary RNFL thickness and vascularization occur, possibly indicating a recovery in such parameters.

RESUMEN

Older adults (aged 55 years and above) have greater difficulty carrying out activities of daily living than younger adults (aged 25−55 years). Although age-related changes in human gait kinetics are well documented in qualitative terms in the scientific literature, these differences may be quantified and analyzed using the analysis of motor control strategies through kinetic synergies. The gaits of two groups of people (older and younger adults), each with ten members, were analyzed on a treadmill at a constant controlled speed and their gait kinetics were recorded. The decomposition of the kinetics into synergies was applied to the joint torques at the hip, knee, and ankle joints. Principal components determined the similarity of the kinetic torques in the three joints analyzed and the effect of the walking speed on the coordination pattern. A total of three principal components were required to describe enough information with minimal loss. The results suggest that the older group showed a change in coordination strategy compared to that of the younger group. The main changes were related to the ankle and hip torques, both showing significant differences (p-value <0.05) between the two groups. The findings suggest that the differences between the gait patterns of the two groups were closely related to a reduction in ankle torque and an increase in hip torque. This change in gait pattern may affect the rehabilitation strategy used when designing general-purpose rehabilitation devices or rehabilitation/training programs for the elderly.

RESUMEN

BACKGROUND: Information is needed on the safety and efficacy of direct discharge from the emergency department (ED) of patients with COVID-19 pneumonia. OBJECTIVES: The objectives of the study were to study the variables associated with discharge from the ED in patients presenting with COVID-19 pneumonia, and study ED revisits related to COVID-19 at 30 days (EDR30d). METHODS: Multicenter study of the SIESTA cohort including 1198 randomly selected COVID patients in 61 EDs of Spanish medical centers from March 1, 2020, to April 30, 2020. We collected baseline and related characteristics of the acute episode and calculated the adjusted odds ratios (aOR) for ED discharge. In addition, we analyzed the variables related to EDR30d in discharged patients. RESULTS: We analyzed 859 patients presenting with COVID-19 pneumonia, 84 (9.8%) of whom weredischarged from the ED. The variables independently associated with discharge were being a woman (aOR 1.890; 95%CI 1.176 3.037), age < 60 years (aOR 2.324; 95%CI 1.353-3.990), and lymphocyte count > 1200/mm3 (aOR 4.667; 95%CI 1.045-20.839). The EDR30d of the ED discharged group was 40.0%, being lower in women (aOR 0.368; 95%CI 0.142-0.953). A totalof 130 hospitalized patients died (16.8%) as did two in the group discharged from the ED (2.4%) (OR 0.121; 95%CI 0.029-0.498). CONCLUSION: Discharge from the ED in patients with COVID-19 pneumonia was infrequent and was associated with few variables of the episode. The EDR30d was high, albeit with a low mortality.

RESUMEN

BACKGROUND: In contrast to cisgender persons, transgender persons identify with a different gender than the one assigned at birth. Although research on the underlying neurobiology of transgender persons has been accumulating over the years, neuroimaging studies in this relatively rare population are often based on very small samples resulting in discrepant findings. AIM: To examine the neurobiology of transgender persons in a large sample. METHODS: Using a mega-analytic approach, structural MRI data of 803 non-hormonally treated transgender men (TM, n = 214, female assigned at birth with male gender identity), transgender women (TW, n = 172, male assigned at birth with female gender identity), cisgender men (CM, n = 221, male assigned at birth with male gender identity) and cisgender women (CW, n = 196, female assigned at birth with female gender identity) were analyzed. OUTCOMES: Structural brain measures, including grey matter volume, cortical surface area, and cortical thickness. RESULTS: Transgender persons differed significantly from cisgender persons with respect to (sub)cortical brain volumes and surface area, but not cortical thickness. Contrasting the 4 groups (TM, TW, CM, and CW), we observed a variety of patterns that not only depended on the direction of gender identity (towards male or towards female) but also on the brain measure as well as the brain region examined. CLINICAL TRANSLATION: The outcomes of this large-scale study may provide a normative framework that may become useful in clinical studies. STRENGTHS AND LIMITATIONS: While this is the largest study of MRI data in transgender persons to date, the analyses conducted were governed (and restricted) by the type of data collected across all participating sites. CONCLUSION: Rather than being merely shifted towards either end of the male-female spectrum, transgender persons seem to present with their own unique brain phenotype.

RESUMEN

ABSTRACT: Martínez-Cabrera, FI, Núñez-Sánchez, FJ, Losada, J, Otero-Esquina, C, Sánchez, H, and De Hoyo, M. Use of individual relative thresholds to assess acceleration in young soccer players according to initial speed. J Strength Cond Res 35(4): 1110-1118, 2021-The aims of the current study were (a) to analyze the characteristics of acceleration efforts using individual relative thresholds according to the initial speed during official matches in elite young soccer players according to player position and (b) to compare the differences between absolute and relative thresholds in assessing high-intensity acceleration. Player acceleration profiles were assessed using an individual relative threshold based on their acceleration capacity at different initial speeds (standing, 6, 10.8, and 15 km·h-1), and the number of accelerations (>75% of the maximal acceleration) performed during soccer matches was divided into 3 categories attending to the initial speed. (S1 = 0-7 km·h-1; S2 = 7.1-14 km·h-1; and S3 = ≥14.1 km·h-1). Within-group analyses showed that the number of accelerations performed in each category was higher when the effort started from a static or walking position than at moderate- or high-intensity running (S1 > S2 > S3; very likely to almost certain). Between-group analyses revealed substantial differences between some playing positions according to initial speed. In S1 and S3, central defenders had the lowest number of accelerations (likely to almost certain), whereas midfielders had the greatest number of high-intensity accelerations in S1 and S2. There were also substantial differences between the other playing positions (possibly to almost certain). Regarding relative and absolute thresholds (>3 m·s-2), the results showed that absolute threshold overestimated the number of high-intensity accelerations compared with the individual relative threshold in S1 and underestimated the results in S2 and S3 (almost certain). The use of an individual relative threshold to measure acceleration demands allows to distinguish between the numbers of accelerations in function of the initial speed and playing positions. In addition, the absolute acceleration threshold could overestimate or underestimate the acceleration demands in young soccer players as a function of the initial speed. Then, the absolute acceleration thresholds should be taken with caution in the assessment of acceleration activities.

RESUMEN

BACKGROUND AND AIMS: Adherence to the Mediterranean diet (MedDiet) has been associated with prolonged survival in older individuals. However, it is unknown whether adherence to MedDiet is associated with the prognosis in older patients scheduled to undergo cardiac resynchronization therapy (CRT). The aim of this study was to evaluate the association between adherence to the MedDiet and clinical outcomes at 12 months follow-up after CRT implantation in older patients. METHODS AND RESULTS: Patients adherents to the MedDiet, defined as ≥ 9 of 14 points using the PREDIMED (Primary Prevention of Cardiovascular Disease with a Mediterranean Diet Study) questionnaire, was assessed before device implantation in patient's ≥ 70 years candidates for CRT. The primary outcome was a combined endpoint at 12 months follow-up after CRT implantation, defined as cardiovascular death, cardiac transplantation or decompensated heart failure. The cohort study consisted of 284 patients with a mean age of 73 ± 3 years. One hundred and fifty-nine (55.9%) patients were classified as adherent to the MedDiet. Seventy (24.6%) patients showed the combined endpoint at one year follow-up. Subjects who did not developed the combined endpoint had higher proportion of adherent patients to the MedDiet compared to patients who developed the combined endpoint (85% vs 67.1%, p = 0.002). After adjustment by possible confounders, the adherence to the MedDiet was a protective and significant predictor of the combined endpoint (HR = 0.42, 95% CI 0.22-0.81; p = 0.01). CONCLUSION: Adherence to the MedDiet is inversely associated with outcome in older patients following CRT.

RESUMEN

AIMS: We aimed to determine the efficacy and safety of sodium-glucose cotransporter type 2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists to prevent worsening urinary albumin-to-creatinine ratio as an early biomarker of diabetes kidney disease. METHODS: A total of 178 patients with type 2 diabetes and obesity received combination treatment with SGLT2i added to GLP1ra (n = 76), GLP1ra added to SGLT2i (n = 50) or GLP1ra plus SGLT2i from start (n = 52), according to investigators´ best clinical judgement. Major outcomes assessed at 26 weeks were changes in urine albumintocreatinine-ratio (UACR), estimated glomerular filtration rate (eGFR), glycated haemoglobin, body weight and systolic blood pressure. RESULTS: All patients (58.6% men, mean age 61.9 ± 10.0 years) completed the study. Baseline HbA1c, weight and eGFR levels were 8.2 ± 0.9%, 109.9 ± 19 kg and 83.3 ± 19.6 mL/min/m2 , respectively. At 26 weeks, we found significant reductions in HbA1c (1.16%), weight (5.17 kg) and systolic blood pressure (8.13 mmHg). The reduction in UACR was 15.14 mg/g (95% CI 8.50-22.4) (-24.6 ± 64.7%), which was greatest in the group of patients with SGLT2i added on to GLP1ra therapy (116.7 mg/g; 95% CI: 54-296.5 mg/g; P < .001. Patients with urinary albumin-to-creatinine ratio ≥30 mg/g, showed a higher declines (63.18 mg/g [95% CI 44.5-104.99]) (-56 ± 65.9%). The greatest reduction in urinary albumin-to-creatinine ratio was obtained when SGLT2i was added to GLP1ra (116.7 mg/g). The eGFR did not significantly change along the study period. CONCLUSION: Our results show the beneficial effect of GLP1ra and SGLT2i combination therapy on early biomarkers of diabetes kidney disease such as albuminuria and in other significant outcomes for diabetes control.

RESUMEN

STUDY OBJECTIVE: We assess the value of the Barthel Index (BI) in predicting 30-day mortality risk among patients with acute heart failure who are attending the emergency department (ED). METHODS: We selected 9,098 acute heart failure patients from the Acute Heart Failure in Emergency Departments registry who had BI score available both at baseline and the ED visit. Patients' data were collected from 41 Spanish hospitals during four 1- to 2-month periods between 2009 and 2016. Unadjusted and adjusted logistic regression models were used to assess the association between 30-day mortality and BI score. c Statistics were used to estimate their prognostic value. RESULTS: The mean baseline BI score was 79.4 (SD 24.6) and the mean ED BI score was 65.3 (SD 29.1). Acute functional decline (≥5-point decrease between baseline BI and ED BI score) was observed in 5,771 patients (53.4%). Within 30 days of the ED visit, 905 patients (9.9%) died. There was a steep inverse gradient in 30-day mortality risk for baseline BI and ED BI score. For instance, compared with BI score=100, a BI score of 50 to 55 doubled the mortality risk both at baseline and the ED visit. At the ED visit, a BI score of 0 to 5 carried a 5-fold increase in risk after adjustment for other risk predictors. In comparison with baseline BI score, ED BI score consistently provided greater discrimination. Neither baseline BI score nor the change in BI score from baseline to the ED visit added further prognostic value to the ED BI score. CONCLUSION: Functional status assessed by the BI score at the ED visit is a strong predictor of 30-day mortality in acute heart failure patients, with higher predictive value than baseline BI score and acute functional decline. Routine recording of BI score at the ED visit may help in decisionmaking and health care planning.

RESUMEN

STUDY OBJECTIVE: The Multiple Estimation of Risk Based on the Emergency Department Spanish Score in Patients With Acute Heart Failure (MEESSI-AHF) is a validated clinical decision tool that characterizes risk of mortality in emergency department (ED) acute heart failure patients. The objective of this study is to compare the distribution of risk categories between hospitalized and discharged ED patients with acute heart failure. METHODS: We included consecutive acute heart failure patients from 34 Spanish EDs. Patients were retrospectively classified according to MEESSI-AHF risk categories. We calculated the odds of hospitalization (versus direct discharge from the ED) across MEESSI-AHF risk categories. Next, we assessed the following 30-day postdischarge outcomes: ED revisit, hospitalization, death, and their combination. We used Cox hazards models to determine the adjusted association between ED disposition decision and the outcomes among patients who were stratified into low- and increased-risk categories. RESULTS: We included 7,930 patients (80.5 years [SD 10.1 years]; women 54.7%; hospitalized 75.3%). Compared with that for low-risk MEESSI-AHF patients, odds ratios for hospitalization of patients in intermediate-, high-, and very-high-risk categories were 1.83 (95% confidence interval [CI] 1.64 to 2.05), 3.05 (95% CI 2.48 to 3.76), and 3.98 (95% CI 3.13 to 5.05), respectively. However, almost half (47.6%) of all discharged patients were categorized as being at increased risk by MEESSI-AHF, and 19.0% of all the increased-risk patients were discharged from the ED. Among the low-risk MEESSI-AHF patients, the 30-day postdischarge mortality did not differ by ED disposition (hazard ratio [HR] for discharged patients with respect to hospitalized ones 0.65; 95% CI 0.70 to 1.11), nor did it differ in the increased-risk group (HR 0.88; 95% CI 0.63 to 1.23). The discharged low-risk MEESSI-AHF patients had higher risks of 30-day ED revisit and hospitalization (HR 1.86, 95% CI 1.57 to 2.20; and HR 1.92, 95% CI 1.54 to 2.40, respectively) compared with the admitted patients, as did the discharged patients in the increased-risk group (HR 1.62, 95% CI 1.39 to 1.89; and HR 1.40, 95% CI 1.16 to 1.68, respectively), with similar results for the combined endpoint. CONCLUSION: The disposition decisions made in current clinical practice for ED acute heart failure patients calibrate with MEESSI-AHF risk categories, but nearly half of the patients currently discharged from the ED fall into increased-risk MEESSI-AHF categories.

RESUMEN

Rigid adherence to traditional male norms has been found to be associated with many health outcomes. This special issue aims to bring together biomedical and psychological researchers as a means to generate interest in integrating scientific approaches so as to advance the health of men and boys. In this guest editorial, the authors first provide a brief review of some key biological factors that contribute to sex differences in health. The editorial then introduces the ten articles included in this special issue, which focus on paternal influence on health-related behaviors; cancer; reproductive and sexual health; eating disorders; and health-related beliefs. Ultimately, by continuing to work across disciplines, those interested in the psychological study of men and masculinities can assist biomedical researchers in promoting better health outcomes.

RESUMEN

OBJECTIVE: To investigate how many patients with acute heart failure (AHF) hypersecrete relaxin-2 concentrations similar to those of pregnant women and determine their long-term outcome. METHODS: In consecutive AHF patients relaxin-2 was quantified by ELISA sandwich method. Patients were divided into pregnancy-like group (PLG, relaxin-2 ≥ 500 pg/mL) and control group (CG, relaxin-2 < 500 pg/mL). The primary outcome was all-cause death during follow-up. Secondary endpoints were prolonged hospitalisation (>10 days), combined endpoint (death, rehospitalisation, ED revisit) 30 days after discharge, and 30-day, one-year and three-year death rates. RESULTS: We included 814 patients [81 (SD = 9) years; 53.0% women] followed during 1.9 (SD 2.8) years; 517 (63.5%) died. Twenty patients (2.5%) formed the PLG (median relaxin-2 = 1459 pg/mL; IQR = 1722) and 794 the CG (median = 26; IQR = 44). There was no interaction with variables included on adjustment (age, sex, ischaemic cardiomyopathy, NT-proBNP, glycaemia, and sodium). PLG patients did not have better short-term secondary endpoints, but did show a significantly lower three-year mortality [ORadjusted = 0.17 (0.05-0.5), p = 0.003]. CONCLUSIONS: The small proportion of AHF patients achieving relaxin-2 concentrations similar to those observed in pregnancy may survive longer.
