RESUMO

Social living affords primates (including humans) many benefits. Communication has been proposed to be the key mechanism used to bond social connections, which could explain why primates have evolved such expressive faces. We assessed whether the facial expressivity of the dominant male (quantified from the coding of anatomically based facial movement) was related to social network properties (based on social proximity and grooming) in nine groups of captive rhesus macaques (Macaca mulatta) housed in uniform physical and social environments. More facially expressive dominant male macaques were more socially connected and had more cohesive social groups. These findings show that inter-individual differences in facial expressivity are related to differential social outcomes at both an individual and group level. More expressive individuals occupy more beneficial social positions, which could help explain the selection for complex facial communication in primates.

RESUMO

Vitamin D is important for musculoskeletal health. Concentrations of 25-hydroxyvitamin D, the most commonly measured metabolite, vary markedly around the world and are influenced by many factors including sun exposure, skin pigmentation, covering, season and supplement use. Whilst overt vitamin D deficiency with biochemical consequences presents an increased risk of severe sequelae such as rickets, osteomalacia or cardiomyopathy and usually warrants prompt replacement treatment, the role of vitamin D supplementation in the population presents a different set of considerations. Here the issue is to keep, on average, the population at a level whereby the risk of adverse health outcomes in the population is minimised. This position paper, which complements recently published work from the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases, addresses key considerations regarding vitamin D assessment and intervention from the population perspective. This position paper, on behalf of the International Osteoporosis Foundation Vitamin D Working Group, summarises the burden and possible amelioration of vitamin D deficiency in global populations. It addresses key issues including screening, supplementation and food fortification.

RESUMO

OBJECTIVES: International studies have shown shifting demographic data and rising hospitalizations for alcohol-related cirrhosis (ARC), with a paucity of data from Australia. We examined hospitalizations, mortality and demographic data for people admitted with ARC over the last decade in Queensland, Australia. STUDY DESIGN: Data linkage study. METHODS: A retrospective analysis of adults hospitalized with ARC during 2008-2019 was performed using state-wide admissions data. International Classification of Diseases, 10th revision, codes identified admissions with the principal diagnosis of ARC based on validated algorithms. Comorbidity was assessed using the Charlson Comorbidity Index. RESULTS: A total of 7152 individuals had 24,342 hospital admissions with ARC (16,388 were for ARC). There was a predominance of males (72.6%) and age ≥50 years (80.4%) at index admission. Females were admitted at a significantly younger age than men (59% of women and 43% of men were aged <60 years, P < 0.001). Comorbidities were common, with 45.1% of people having at least one comorbidity. More than half (54.6%) of the patients died over the study period (median follow-up time was 5.1 years; interquartile range 2.4-8.6). Women had significantly lower mortality, with 47.6% (95% confidence interval [CI] 45.0-50.2) probability of 5-year survival, compared with 40.1% (95% CI 38.5-41.6) in men. In multivariable analysis, this was attributable to significantly lower age and comorbidity burden in women. Significantly lower survival was seen in people with higher comorbidity burden. Overall, the number of admissions for ARC increased 2.2-fold from 869 admissions in 2008 to 1932 in 2019. CONCLUSIONS: Hospital admissions for ARC have risen substantially in the last decade. Females were admitted at a younger age, with fewer comorbidities and had lower mortality compared with males. The association between greater comorbidity burden and higher mortality has important clinical implications, as comorbidity-directed interventions may reduce mortality.

RESUMO

Electronic Medical Records (EMRs) are a tool that could potentially improve the outcomes of patient care by providing physicians with access to up-to-date and accurate vital patient information. Despite this potential, EMR adoption in developing economies has been dilatory. This systematic review aims to synthesize the related literature on the adoption of EMRs in developing economies, with a focus on the perspective of physicians. With the aim to discern the key factors that impact EMR adoption as perceived by physicians and to offer guidance for future research on filling any gaps identified in the existing literature, this study utilized a systematic literature review by following the PRISMA guidelines. Out of 1160 initial articles, 21 were selected for analysis after eliminating duplicates and non-qualifying articles. Results show that common enablers of EMR adoption from physicians' perspective were identified to be computer literacy, education, voluntariness, and the system functionality including its features and user interface, implying that the provision of proper interventions focusing on the aspects of the health information system has an impact in maximizing the utilization and capabilities of EMRs among healthcare providers. The most prevalent barriers include the lack of training and IT usage experience along with resistance to changes associated with respondents' age and gender, the lack of time for learning complex EMR systems, and costs of the new technology. This indicates that a thorough planning and proper budget allocation is necessary prior to implementing and integrating EMR systems in healthcare institutions. From this synthesis of the common research conclusions, limitations, and recommendations from physicians' perspective, the result of this systematic review is expected to shed light on the optimal technology adoption of EMRs and its contribution to the health care systems of developing economies.

RESUMO

Cerebral air embolism (CAE) is a rare, yet potentially devastating condition characterized by entrance of air into cerebral vasculature, that is nearly always iatrogenic. While many findings of CAE are subclinical and incidental at computed tomography (CT), there remain cases of catastrophic and fatal embolisms. Increasing physician awareness of prevention, presentation, and treatment for CAE is crucial for reducing morbidity and mortality. In this case series, we highlight this preventable entity by comparing three cases of CAE that showcase a diverse array of presentations, radiologic findings, and clinical outcomes. We will also explore predisposing factors, prognostic predictors, diagnostic considerations, and available treatments.

RESUMO

BACKGROUND: There is a pressing need for healthcare to respond to the climate crisis. Family physicians, given their central role in community healthcare provision, are strategically placed to lead, support, and promote sustainable healthcare, yet guidance on how to do this is fragmented. OBJECTIVE: To identify and evaluate toolkits and aids on sustainable healthcare to act as a curated resource for family physicians and their care teams interested in delivering evidence-based sustainable healthcare in their clinical practices. METHODS: A scoping review was completed of the published and grey literature across 4 databases and 2 search engines to identify articles and aids/toolkits from 1990 to present. Toolkits were subsequently evaluated for purpose, evidence-base, implementation process, adaptability to family medicine, and outcome measures. RESULTS: The search identified 17,751 articles. Screening resulted in 20 published articles and 11 toolkits. Most articles presented simple checklists to support greening clinic initiatives, 3 studies focussed on partial carbon footprint analyses, and 4 on educational initiatives. Toolkits ranged in sustainability topics and degree of depth covered, and adaptability and outcome measures. None of the resources identified have been formally evaluated for effectiveness. CONCLUSIONS: A range of aids exist to support greening of clinic operations; however, there is a significant gap in the literature for greening clinical care. Two toolkits were found to be comprehensive, one requiring tracking and reporting of sustainability initiatives. This scoping review provides a starting point for motivated family doctors and community clinics to initiate change and support more sustainable healthcare.

RESUMO

The IOF Epidemiology and Quality of Life Working Group has reviewed the potential role of population screening for high hip fracture risk against well-established criteria. The report concludes that such an approach should strongly be considered in many health care systems to reduce the burden of hip fractures. INTRODUCTION: The burden of long-term osteoporosis management falls on primary care in most healthcare systems. However, a wide and stable treatment gap exists in many such settings; most of which appears to be secondary to a lack of awareness of fracture risk. Screening is a public health measure for the purpose of identifying individuals who are likely to benefit from further investigations and/or treatment to reduce the risk of a disease or its complications. The purpose of this report was to review the evidence for a potential screening programme to identify postmenopausal women at increased risk of hip fracture. METHODS: The approach took well-established criteria for the development of a screening program, adapted by the UK National Screening Committee, and sought the opinion of 20 members of the International Osteoporosis Foundation's Working Group on Epidemiology and Quality of Life as to whether each criterion was met (yes, partial or no). For each criterion, the evidence base was then reviewed and summarized. RESULTS AND CONCLUSION: The report concludes that evidence supports the proposal that screening for high fracture risk in primary care should strongly be considered for incorporation into many health care systems to reduce the burden of fractures, particularly hip fractures. The key remaining hurdles to overcome are engagement with primary care healthcare professionals, and the implementation of systems that facilitate and maintain the screening program.

RESUMO

Oxygen isotope speleothem records exhibit coherent variability over the pan-Asian summer monsoon (AM) region. The hydroclimatic representation of these oxygen isotope records for the AM, however, has remained poorly understood. Here, combining an isotope-enabled Earth system model in transient experiments with proxy records, we show that the widespread AM δ18Oc signal during the last deglaciation (20 to 11 thousand years ago) is accompanied by a continental-scale, coherent hydroclimate footprint, with spatially opposite signs in rainfall. This footprint is generated as a dynamically coherent response of the AM system primarily to meltwater forcing and secondarily to insolation forcing and is further reinforced by atmospheric teleconnection. Hence, widespread δ18Op depletion in the AM region is accompanied by a northward migration of the westerly jet and enhanced southwesterly monsoon wind, as well as increased rainfall from South Asia (India) to northern China but decreased rainfall in southeast China.

RESUMO

OBJECTIVE: The objective of this study is to evaluate associations between webcam use in the neonatal intensive care unit (NICU) with parental stress and nursing work-related stress and burnout. DESIGN: Prospective validated and de novo questionnaires administered to NICU parents and nurses during two observation periods: (1) no webcam access (off webcam) and (2) webcam access (on webcam). RESULTS: Seventy-nine "off webcam" parents, 80 "on webcam" parents, and 35 nurses were included. Parental stress levels were significantly lower "on webcam" and perceptions of the technology were overwhelmingly positive. There were no significant differences in nursing stress levels and burnout between periods. Only 14% of nurses believed that webcam use improves infant's quality of care. Majority nurses felt that webcams increase parental and nursing stress. CONCLUSIONS: Webcam use in the NICU is associated with lower parental stress levels and has no effect on nursing stress levels or work-related burnout. These findings contradict nurses' beliefs that webcams increase parent and nurse stress.

RESUMO

To date, projections of human migration induced by sea-level change (SLC) largely suggest large-scale displacement away from vulnerable coastlines. However, results from our model of Bangladesh suggest counterintuitively that people will continue to migrate toward the vulnerable coastline irrespective of the flooding amplified by future SLC under all emissions scenarios until the end of this century. We developed an empirically calibrated agent-based model of household migration decision-making that captures the multi-faceted push, pull and mooring influences on migration at a household scale. We then exposed ~4800 000 simulated migrants to 871 scenarios of projected 21st-century coastal flooding under future emissions pathways. Our model does not predict flooding impacts great enough to drive populations away from coastlines in any of the scenarios. One reason is that while flooding does accelerate a transition from agricultural to non-agricultural income opportunities, livelihood alternatives are most abundant in coastal cities. At the same time, some coastal populations are unable to migrate, as flood losses accumulate and reduce the set of livelihood alternatives (so-called 'trapped' populations). However, even when we increased access to credit, a commonly-proposed policy lever for incentivizing migration in the face of climate risk, we found that the number of immobile agents actually rose. These findings imply that instead of a straightforward relationship between displacement and migration, projections need to consider the multiple constraints on, and preferences for, mobility. Our model demonstrates that decision-makers seeking to affect migration outcomes around SLC would do well to consider individual-level adaptive behaviors and motivations that evolve through time, as well as the potential for unintended behavioral responses.

RESUMO

Core principles for fracture prevention address fundamental concepts for the evaluation and management of patients at risk for fracture. These are intended to form the foundation of clinical practice guidelines and represent a first step toward guideline harmonization. INTRODUCTION: The large number of clinical practice guidelines for osteoporosis and discordance of recommendations has led to confusion among clinicians and patients, and likely contributes to the large osteoporosis treatment gap. We propose that stakeholder organizations reach agreement on fundamental principles in the management of osteoporosis and prevention of fracture as a first step toward a goal of guideline harmonization. METHODS: The best available evidence, as interpreted by an ad hoc working group of expert representatives from major osteoporosis societies in North America, was considered in the development of core principles for skeletal healthcare. These principles were subsequently endorsed by the USA National Osteoporosis Foundation, Osteoporosis Canada, and Academia Nacional de Medicina de Mexico (National Academy of Medicine of Mexico). RESULTS: Core principles are summarized here in bullet format. Categories include evaluation, lifestyle and nutrition, pharmacological therapy, and monitoring. A pathway forward to achieve guideline harmonization, at least in part, is proposed. CONCLUSION: Greater concordance of recommendations for the care of patients at risk for fracture are expected to lead to improved patient care across jurisdictions, with a narrowing of the osteoporosis treatment gap and reduced burden of fractures.

RESUMO

The aim of the present study was to evaluate "flushable" and "non-flushable" wet wipes as a source of plastic pollution in the River Thames at Hammersmith, London and the impacts they have on the invasive Asian clam, Corbicula fluminea, in this watercourse. Surveys were conducted to assess whether the density of wet wipes along the foreshore upstream of Hammersmith Bridge affected the distribution of C. fluminea. High densities of wet wipes were associated with low numbers of clams and vice versa. The maximum wet wipe density recorded was 143 wipes m-2 and maximum clam density 151 individuals m-2. Clams adjacent to the wet wipe reefs were found to contain synthetic polymers including polypropylene (57%), polyethylene (9%), polyallomer (8%), nylon (8%) and polyester (3%). Some of these polymers may have originated from the wet wipe reefs.

RESUMO

Leucine, nutrient signal and substrate for the branched chain aminotransferase (BCAT) activates the mechanistic target of rapamycin (mTORC1) and regulates autophagic flux, mechanisms implicated in the pathogenesis of neurodegenerative conditions such as Alzheimer's disease (AD). BCAT is upregulated in AD, where a moonlighting role, imparted through its redox-active CXXC motif, has been suggested. Here we demonstrate that the redox state of BCAT signals differential phosphorylation by protein kinase C (PKC) regulating the trafficking of cellular pools of BCAT. We show inter-dependence of BCAT expression and proteins associated with the P13K/Akt/mTORC1 and autophagy signalling pathways. In response to insulin or an increase in ROS, BCATc is trafficked to the membrane and docks via palmitoylation, which is associated with BCATc-induced autophagy through PKC phosphorylation. In response to increased levels of BCATc, as observed in AD, amyloid ß (Aß) levels accumulate due to a shift in autophagic flux. This effect was diminished when incubated with leucine, indicating that dietary levels of amino acids show promise in regulating Aß load. Together these findings show that increased BCATc expression, reported in human AD brain, will affect autophagy and Aß load through the interdependence of its redox-regulated phosphorylation offering a novel target to address AD pathology.

RESUMO

Voluntary exercise increases stress resistance by modulating stress-responsive neurocircuitry, including brainstem serotonergic systems. However, it remains unknown how exercise produces adaptations to serotonergic systems. Recruitment of serotonergic systems during repeated, daily exercise could contribute to the adaptations in serotonergic systems following exercise, but whether repeated voluntary exercise recruits serotonergic systems is unknown. In this study, we investigated the effects of six weeks of voluntary or forced exercise on rat brain serotonergic systems. Specifically, we analyzed c-Fos and FosB/ΔFosB as markers of acute and chronic cellular activation, respectively, in combination with tryptophan hydroxylase, a marker of serotonergic neurons, within subregions of the dorsal raphe nucleus using immunohistochemical staining. Compared to sedentary controls, rats exposed to repeated forced exercise, but not repeated voluntary exercise, displayed decreased c-Fos expression in serotonergic neurons in the rostral dorsal portion of the dorsal raphe nucleus (DRD) and increased c-Fos expression in serotonergic neurons in the caudal DR (DRC), and interfascicular part of the dorsal raphe nucleus (DRI) during the active phase of the diurnal activity rhythm. Similarly, increases in c-Fos expression in serotonergic neurons in the DRC, DRI, and ventral portion of the dorsal raphe nucleus (DRV) were observed in rats exposed to repeated forced exercise, compared to rats exposed to repeated voluntary exercise. Six weeks of forced exercise, relative to the sedentary control condition, also increased FosB/ΔFosB expression in DRD, DRI, and DRV serotonergic neurons. While both voluntary and forced exercise increase stress resistance, these results suggest that repeated forced exercise, but not repeated voluntary exercise, increases activation of DRI serotonergic neurons, an effect that may contribute to the stress resistance effects of forced exercise. These results also suggest that mechanisms of exercise-induced stress resistance may differ depending on the controllability of the exercise.

RESUMO

Understanding the role nicotine plays in initiating and sustaining addiction has been of interest for the scientific community and general population, with the idea that low levels of nicotine will reduce abuse liability associated with smokeless tobacco products. Previously, research has relied on subjective assessments to determine consumer acceptability, but these measures cannot provide a characterization of the physiological responses associated with nicotine use. Consumer acceptability arises from psychological and neurophysiological factors, thus establishing the need to use subjective and objective measurements in conjunction. This study provides a comprehensive characterization of the subjective and objective effects of smokeless tobacco product use with varying levels of nicotine. EEG data were recorded before and after the use of four different smokeless tobacco products and one control product over five separate visits, with participants arriving to each visit after 12 h of tobacco abstinence. These products have distinct consumer acceptability levels and patterns of use characteristics ranging from starter products to those used primarily by established users. Subjective results showed that smokeless tobacco products with higher levels of nicotine were more successful in reducing craving and more reinforcing than those with lower levels. These results were concordant with the activity present in the EEG recordings where products with high nicotine levels produced larger changes in the amplitude of the event-related signal than those with low levels. This study is fundamental in understanding the relationship between subjective and objective smokeless tobacco acceptability measurements, as mediated by the different levels of nicotine in each product.

RESUMO

Electronic nicotine delivery systems (ENDS) are devices that contain a power source, a heating element, and a tank or cartridge containing an "e-liquid," which is a mixture of nicotine and flavoring in a glycerol-propylene glycol vehicle. Their increasing popularity among adolescents might be attributed to aggressive marketing in physical venues, social media outlets, as well as irreversible changes caused by nicotine in the developing brains of youth and young adults, predisposing them to addictive behaviors. Adolescent ENDS users were 4 times more likely to initiate cigarette smoking, and the odds of quitting smoking were lower and, in many instances, delayed for those using ENDS. ENDS also renormalize cigarette-like behaviors, such as inhaling/exhaling smoke. The oral cavity is the initial point of contact of ENDS and the first affected system in humans. Oral health depends on an intricate balance in the interactions between oral bacteria and the human immune system, and dysbiosis of oral microbial communities underlies the etiology of periodontitis, caries, and oral cancer. Emerging evidence from subjects with periodontitis as well as periodontally healthy subjects demonstrates that e-cigarette use is associated with a compositional and functional shift in the oral microbiome, with an increase in opportunistic pathogens and virulence traits.

RESUMO

BACKGROUND: Inclusion body disease (IBD) is a disease of snakes with a global distribution and has recently been shown to be caused by reptarenaviruses. Testing for this group of viruses in asymptomatic snakes allows the association between infection and disease to be further elucidated. METHODS: A reptarenavirus was detected by RT-PCR in a reticulated python (Malayopython reticulatus) from an Australian zoological collection that was open-mouth breathing and had erythematous oral mucosa. Another 27 pythons, 4 elapids, 2 colubrids and 2 boas from this collection were then screened. From these animals, swabs, whole blood and/or tissue were tested for reptarenaviruses by RT-PCR. Additionally, blood films from 10 snakes were examined by light microscopy for the presence of inclusion bodies. The majority of samples were collected over a 484-day period. RESULTS: A total of 8 animals were RT-PCR-positive (8/36 = 22.2%): 6 were pythons, 1 was a corn snake (Pantherophis guttatus) and 1 was a Madagascar tree boa (Sanzinia madagascariensis). From them, 57 samples were collected, but only one from each animal was RT-PCR-positive (8/57 = 14.0%). From all 36 animals in this study, 8/182 samples were RT-PCR-positive (4.4%). Inclusion bodies were not recognised in any of the blood films. Only the reticulated python showed signs of illness, which improved without any further intervention. All other RT-PCR-positive snakes were apparently healthy throughout the duration of the study. CONCLUSION: This study showed a weak association between the presence of reptarenaviruses and disease. Testing serially collected swab and whole-blood samples increased the number of animals in which reptarenaviruses were detected.

RESUMO

Age-specific intervention and assessment thresholds were developed for seven Latin American countries. The intervention threshold ranged from 1.2% (Ecuador) to 27.5% (Argentina) at the age of 50 and 90 years, respectively. In the Latin American countries, FRAX offers a substantial advance for the detection of subjects at high fracture risk.INTRODUCTION:Intervention thresholds are proposed using the Fracture Risk Assessment (FRAX) tool. We recommended their use to calculate the ten-year probability of fragility fracture (FF) in both, men and women with or without the inclusion of bone mineral density (BMD). The purpose of this study is to compute FRAX-based intervention and BMD assessment thresholds for seven Latin American countries in men and women ≥ 40 years.METHODS:The intervention threshold (IT) was set at a 10-year probability of a major osteoporotic fracture (MOF) equivalent to a woman with a prior FF and a body mass index (BMI) equal to 25.0 kg/m2 without BMD or other clinical risk factors. The lower assessment threshold was set at a 10-year probability of a MOF in women with BMI equal to 25.0 kg/m2, no previous fracture and no clinical risk factors. The upper assessment threshold was set at 1.2 times the IT.RESULTS:For the seven LA countries, the age-specific IT varied from 1.5 to 27.5% in Argentina, 3.8 to 25.2% in Brazil, 1.6 up to 20.0% in Chile, 0.6 to 10.2% in Colombia, 0.9 up to 13.6% in Ecuador, 2.6 to 20.0% in Mexico, and 0.7 up to 22.0% in Venezuela at the age of 40 and 90 years, respectively.CONCLUSIONS:In the LA countries, FRAX-based IT offers a substantial advance for the detection of men and women at high fracture risk, particularly in the elderly. The heterogeneity of IT between the LA countries indicates that country-specific FRAX models are appropriate rather than a global LA model (AU)

RESUMO

Worldwide, musculoskeletal (MSK) disorders are the second cause of living with disability. According to our data, in Mexico, MSK conditions are an important cause of disability, at national and state level. Preventive actions promoted by health systems to reduce the burden of MSK disorders are essential. INTRODUCTION: We describe premature mortality and disability due to musculoskeletal (MSK) disorders in Mexico at national and state level from 1990 to 2016. METHODS: Using data from the global burden of disease study 2016 (GBD 2016), we present rates and trends in years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALYs) caused by MSK disorders in Mexico by state from 1990 to 2016. The burden of MSK disorders was computed using standard GBD methodology. To compare the burden of MSK disorders across the country, states were grouped by sociodemographic index (SDI). RESULTS: In Mexico, MSK disorders were the 3rd and 17th greatest cause of YLDs and YLLs in 2016, respectively, accounting for 1.95 million (95% UI 1.4-2.5) DALYs. Among all MSK disorders, low back and neck pain had the highest all-ages DALYs rate and represented 3.6% of total DALYs. All-ages YLLs and YLDs rates of MSK disorders were 234 and 37% higher in females (YLLs 102.2, 95% UI 79.9-110.7; YLDs 1677.9, 95% UI 1213.5-2209.4) than in males (YLLs 30.6, 95% UI 28.3-34.0; YLDs 1224.7, 95% UI 887.2-1608.3), respectively. Northern and high SDI states had higher rates of MSK disorders in comparison with southern and low SDI states. Only 16% of YLDs caused by all MSK disorders could be attributed to risk factors currently assessed in GBD. CONCLUSION: MSK conditions are an important cause of premature mortality and disability. Researcher engagement and cross-sectorial actions to address the burden of MSK disorders are essential.
