A Novel Web-Based and Mobile Application to Measure Real-Time Moral Distress: An Initial Pilot and Feasibility Study.

Moral distress (MoD) is a vital clinical indicator linked to clinician burnout and provider concerns about declining patient care quality. Yet it is not routinely assessed. Earlier, real-time recognition may better target interventions aimed at alleviating MoD and thereby increase provider well-being and improve patient care quality. Combining two validated MoD instruments (the Moral Distress Thermometer [MDT] and the Measure of Moral Distress for Healthcare Professionals [MMD-HP]), the authors developed a novel mobile and Web-based application environment to measure and report levels MoD and their associated causes. This app was tested for basic feasibility and acceptability in two groups: graduate nursing students and practicing critical care nurses. The MDT app appears feasible and acceptable for future use. All participants (n = 34) indicated the MDT app was satisfying to use, and 91.2% (n = 31) indicated the app was "very appropriate" for measuring MoD. In addition, 84.2% (n =16) of practicing nurses indicated the app fit either "somewhat well" (47.4%, n = 9) or "very well" (36.8%, n = 7) into their typical workday, and 68.4% (n = 13) said they were either "extremely likely" or "somewhat likely" to use the app daily in clinical practice. Education about moral distress and its associated causes proved important to the MDT app's success. It is ready for future validity and reliability testing, as well as examining usability beyond nursing, longitudinal data monitoring, and possible leveraging to pre- and postintervention evaluation studies.

Current challenges in the prevention and management of post-thrombotic syndrome-towards improved prevention.

Post-thrombotic syndrome (PTS) is a common and potentially debilitating complication of deep vein thrombosis (DVT), affecting up to 50% of DVT patients. The consequence of this chronic condition includes reduced quality of life, increased use of the healthcare system and decreased productivity. The societal impact of this condition is projected to increase, given our ageing population and increased burden of thrombotic diseases. Despite significant recent advances in our understanding of PTS, many unanswered questions remain. Currently, there are few effective and proven options for established PTS; hence, the emphasis should be on instituting effective prevention to reduce the progression to PTS. Effective anticoagulation lowers the risk of PTS, with direct oral anticoagulants appearing to outperform vitamin-K antagonists. However, the evidence for elastic compression stockings and endovascular thrombolysis or thrombectomy techniques remains unclear. Accurate identification of individuals at high risk of developing PTS may also improve the targeting of preventative interventions. This review will examine the current body of evidence regarding PTS, with a focus on preventative strategies as well as novel biomarkers.

Focus on the impact of social factors and lifestyle on the disease burden of low back pain: findings from the global burden of disease study 2019

BackgroundLow back pain (LBP) is one of the leading causes of disability worldwide. Differences in social backgrounds and lifestyles in various regions and countries may contribute to the discrepancies in the disease burden of LBP.MethodsBased on the GBD 2019, we collected and analyzed numbers and age-standardized rates (ASR) of LBP disability-adjusted life years (DALYs). Temporal trends in ASR were also analyzed using estimated annual percentage change (EAPC). The Age-period-cohort (APC) model was used to estimate age, period and cohort trends in DALYs of LBP. An autoregressive integrated moving average (ARIMA) model was used to forecast DALYs of LBP trends from 2020 to 2035.ResultsThe DALYs due to LBP increased from 1990 to 2019. The APC model showed that the risk of DALYs for global LBP increased with age and year and that the risk of DALYs was lower in the later-born cohort than in the earlier-born cohort. The main risk factors which GBD estimates were available for DALYs of LBP include smoking, occupational ergonomic factors and high BMI. It is expected that DALYs of LBP will continue to rise until 2035.ConclusionFrom 1990 to 2019, the global disease burden of LBP remained high. It is necessary to pay attention to the influence of social factors and lifestyle on LBP. Focusing on the impact of social factors as well as lifestyle on the prognosis of LBP and targeting interventions may further reduce the disease burden of LBP.

Selective Prevention of Depression in Workers Using a Smartphone App: Randomized Controlled Trial.

There is increasing evidence that depression can be prevented; however, universal approaches have had limited success. Appropriate targeting of interventions to at-risk populations has been shown to have potential, but how to selectively determine at-risk individuals remains unclear. Workplace stress is a risk factor for depression and a target for intervention, but few interventions exist to prevent depression among workers at risk due to heightened stress. This trial aimed to evaluate the efficacy of a smartphone-based intervention in reducing the onset of depression and improving related outcomes in workers experiencing at least moderate levels of stress. A randomized controlled trial was conducted with participants who were currently employed and reported no clinically significant depression and at least moderate stress. The intervention group (n=1053) were assigned Anchored, a 30-day self-directed smartphone app-based cognitive behavioral- and mindfulness-based intervention. The attention-control group (n=1031) were assigned a psychoeducation website. Assessment was performed via web-based self-report questionnaires at baseline and at 1-, 3-, and 6-month postbaseline time points. The primary outcome was new depression caseness aggregated over the follow-up period. The secondary outcomes included depressive and anxiety symptoms, stress, well-being, resilience, work performance, work-related burnout, and quality of life. Analyses were conducted within an intention-to-treat framework using mixed modeling. There was no significant between-group difference in new depression caseness (z score=0.69; P=.49); however, those in the Anchored arm had significantly greater depressive symptom reduction at 1 month (Cohen d=0.02; P=.049) and 6 months (Cohen d=0.08; P=.03). Anchored participants also showed significantly greater reduction in anxiety symptoms at 1 month (Cohen d=0.07; P=.04) and increased work performance at 1 month (Cohen d=0.07; P=.008) and 6 months (Cohen d=0.13; P=.01), compared with controls. Notably, for Anchored participants completing at least two-thirds of the intervention, there was a significantly lower rate of depression onset (1.1%, 95% CI 0.0%-3.7%) compared with controls (9.0%, 95% CI 6.8%-12.3%) at 1 month (z score=4.50; P<.001). Significant small to medium effect sizes for most secondary outcomes were seen in the highly engaged Anchored users compared with controls, with effects maintained at the 6-month follow-up for depressive symptoms, well-being, stress, and quality of life. Anchored was associated with a small comparative reduction in depressive symptoms compared with controls, although selective prevention of case-level depression was not observed in the intention-to-treat analysis. When users adequately engaged with the app, significant findings pertaining to depression prevention, overall symptom reduction, and functional improvement were found, compared with controls. There is a need for a greater focus on engagement techniques in future research.

Correlates of child mental health and substance use related emergency department visits in Ontario: A linked population survey and administrative health data study.

Knowledge of the sociodemographic, behavioural, and clinical characteristics of children visiting emergency departments (EDs) for mental health or substance use concerns in Ontario, Canada is lacking. Using data from a population-based survey linked at the individual level to administrative health data, this study leverages a provincially representative sample and quasi-experimental design to strengthen inferences regarding the extent to which children's sociodemographic, behavioural, and clinical characteristics are associated with the risk of a mental health or substance use related ED visit. 9,301 children aged 4-17 years participating in the 2014 Ontario Child Health Study were linked retrospectively (6 months) and prospectively (12 months) with administrative health data on ED visits from the National Ambulatory Care Reporting System. Modified Poisson regression was used to examine correlates of mental health and substance use related ED visits among children aged 4-17 years over a 12-month period following their survey completion date, adjusting for ED visits in the 6 months prior to their survey completion date. Subgroup analyses of youths aged 14-17 years who independently completed survey content related to peer victimisation, substance use, and suicidality were also conducted. Among children aged 4-17 years, older age, parental immigrant status, internalising problems, and perceived need for professional help were statistically significant correlates that increased the risk of a mental health or substance use related ED visit; low-income and suicidal ideation with attempt were statistically significant only among youths aged 14-17 years. Knowledge of the sociodemographic, behavioural, and clinical characteristics of children visiting EDs for mental health and substance use related concerns is required to better understand patient needs to coordinate effective emergency mental health care that optimises child outcomes, and to inform the development and targeting of upstream interventions that have the potential to prevent avoidable ED visits. Growing rates of child mental health and substance use related ED visits have been observed internationally.A population-based survey linked at the individual level to administrative health data was used to examine the extent to which children's sociodemographic, behavioural, and clinical characteristics are associated with the risk of a mental health or substance use related ED visit in Ontario, Canada.Older age, low-income, parental immigrant status, perceived need for professional help, internalising problems, and suicidality increase the risk of an ED visit.Knowledge of the characteristics of children visiting EDs can be used to coordinate effective emergency mental health care that optimises child outcomes, and to inform the development and targeting of upstream interventions that have the potential to prevent avoidable ED visits.

The effect of childhood trauma and resilience on psychopathology in adulthood: Does bullying moderate the associations?

BackgroundExposure to traumatic events in childhood, including bullying, can negatively affect physical and mental health in adulthood. The aim of the present study was to determine the prevalence of bullying in different sociodemographic groups of the Slovak Republic and to assess the moderating effect of bullying on the associations between childhood trauma, resilience, and the later occurrence of psychopathology.MethodsFor the analyses, a representative sample of the population of the Slovak Republic was used (N = 1018, mean age 46.24 years, 48.7% of men). Multivariate linear regression models were used to investigate the predictive ability of childhood trauma (The Childhood Trauma Questionnaire, CTQ) and resilience (The Brief Resilience Scale, BRS) to explain psychopathology (The Brief Symptom Inventory, BSI-53). Bullying (The Adverse Childhood Experiences – International Questionnaire, ACE-IQ) was used as a moderator.ResultsIn total, 13.5% of respondents have experienced bullying. The most common form of bullying was making fun of someone because of how their body or face looked (46.7%) and excluding someone from activities or ignoring them (36.5%). Higher scores in all types of psychopathology and the Global Severity Index (GSI) were significantly associated with higher scores of emotional and sexual abuse, and some of them with physical neglect. The protective effect of resilience was moderated by bullying in several types of psychopathology, specifically in somatization, obsessive-compulsive, interpersonal sensitivity, depression, psychoticism, and the GSI.ConclusionUnderstanding the links between childhood trauma, bullying, and later psychopathology can help professionals target policies, resources, and interventions to support children and families at risk. Every child should feel accepted and safe at home and school.

Characterizing Drug use Typologies and Their Association with Sexual Risk Behaviors: A Latent Class Analysis Among Men who have Sex with Men in Mexico

Abstract Introduction Drug use behaviors are closely associated with increased risk for HIV and other STIs among men who have sex with men (MSM) globally. Less is known about the drug use characteristics and their association with HIV/STI risk among MSM in Mexico, who have 13 times higher risk of acquiring HIV than the general population. We characterized distinct classes of drug use behaviors among a nationwide sample of MSM in Mexico and tested their associations with HIV risk behaviors. Methods We used latent class analysis (LCA) to analyze injection/non-injection drug use data collected by the online Encuesta de Sexo Entre Hombres self-administered survey among 15,875 MSM living in Mexico between May-June 2017. MSM were recruited on general social media sites (e.g. Facebook and Twitter), popular LGBT + focused web pages (e.g. Soy Homosensual and Desastre), and dating apps (e.g. Grindr and Hornet). We used robust Poisson regression to examine associations between drug use classes and recent sexual risk behaviors while adjusting for sociodemographic characteristics. Results Most participants were under 30 years of age (65.5%), received a Bachelor’s degree or higher (65.2%), gay-identified (82.5%), HIV negative (58.1%), and lived in the Mexico City/State of Mexico region (34.5%). We identified five distinct drug use classes: Limited Drug Use (75.4%), Marijuana Only (15.1%), Sex Event Popper + Marijuana (4.3%), Club Drug + Marijuana (4.2%), and Elevated Polydrug Use (1.0%). Compared to the Limited Drug Use class, participants in all other drug use classes were significantly more likely to engage in condomless anal intercourse (aPR = 1.14–1.39; p &lt; 0.001), sex exchange (aPR = 1.37–4.99; p &lt; 0.001), anonymous sex (aPR = 1.22–2.01; p &lt; 0.001), group sex (aPR = 1.50–3.28; p &lt; 0.001), and report an STI diagnosis in the past 12 months (aPR = 1.24–2.20; p &lt; 0.002). Estimates were largest among the Elevated Polydrug Use class. Conclusions This study is the first to characterize drug use behaviors and HIV/STI risk among a national sample of MSM in Mexico. Understanding how distinct combinations of drug use behaviors impact sexual risk and prevention behaviors among MSM can inform how best to target and tailor future interventions to reduce HIV/STI incidence.

A prospective study on body image disturbances during pregnancy and postpartum: the role of cognitive reappraisal.

During pregnancy, body size rapidly modifies over a relatively short period. Literature emphasizes the need to identify the factors that influence body image during peripartum as the extent of women's adaptation to these changes has significant repercussions on both mother's and newborn's health. Emotion regulation strategies (i.e., expressive suppression and cognitive reappraisal) were linked to body image in the general and clinical population, but no studies were conducted in the peripartum. The present study aims to investigate the longitudinal impact of prepartum body image disturbances on postpartum body image disturbances and to evaluate the mediational role of emotional regulation strategies. A total of 133 pregnant women completed a three-phase longitudinal study. Women answered online questionnaires during the second (T1) and the third (T2) trimesters of pregnancy, and at about 6 months postpartum (T3). Findings indicated that body image disturbances at T1 were a significant predictor of body image disturbances in the postpartum (1 year after the first assessment). Moreover, cognitive reappraisal measured at T2 partially mediated this relationship: body image disturbances in the second trimester of pregnancy were linked to less use of cognitive reappraisal in the third trimester of pregnancy, and this, in turn, was associated with worse body image disturbances at 6 months after birth. Findings of this longitudinal study highlight the importance of assessing body image disturbances during pregnancy to early identify women at risk, and suggest cognitive reappraisal as a possible target intervention.

Nanotechnology translation in vascular diseases: From design to the bench.

Atherosclerosis is a systemic pathophysiological condition contributing to the development of majority of polyvascular diseases. Nanomedicine is a novel and rapidly developing science. Due to their small size, nanoparticles are freely transported in vasculature, and have been widely employed as tools in analytical imaging techniques. Furthermore, the application of nanoparticles also allows target intervention, such as drug delivery and tissue engineering regenerative methods, in the management of major vascular diseases. Therefore, by summarizing the physical and chemical characteristics of common nanoparticles used in diagnosis and treatment of vascular diseases, we discuss the details of these applications from cellular, molecular, and in vivo perspectives in this review. Furthermore, we also summarize the status and challenges of the application of nanoparticles in clinical translation. This article is categorized under: Therapeutic Approaches and Drug Discovery > Nanomedicine for Cardiovascular Disease Implantable Materials and Surgical Technologies > Nanomaterials and Implants Therapeutic Approaches and Drug Discovery > Emerging Technologies.

High risk of rehospitalization within 1 year following a pulmonary embolism-insights from the Danish nationwide registries from 2000-2020.

To identify the absolute risk, causes, and factors associated with rehospitalization within 1 year of discharge with a pulmonary embolism (PE). Using the Danish nationwide registries, all patients admitted with a first-time PE between 2000 and 2020 and discharged alive were included. Subsequent hospitalizations were categorized and crude cumulative incidences were used to estimate the absolute risk (AR) of any rehospitalization and specific causes of rehospitalizations. Risk factors for rehospitalization were investigated using cause specific Cox regression models.A total of 55 201 patients were identified. The median age of the study population was 70 years (inter quartile range: 59;79), and the most prevalent comorbidities were cancer (29.3%) and ischemic heart disease (12.7%). The 1-year AR of any rehospitalization after discharge with a PE was 48.6% (95% confidence interval (CI); 48.2%-48.8%). The most common cause for being rehospitalized was due to respiratory disease [1-year AR: 9.5% (95% CI: 9.3%-9.8%)], followed by cardiovascular disease [1-year AR: 6.3% (95% CI: 5.9%-6.5%)], cancer [1-year AR: 6.0% (95% CI: 5.8%-6.4%)], venous thromboembolism [1-year AR: 5.2% (95% CI: 5.0%-5.2%)], and symptom diagnoses [1-year AR: 5.2% (95% CI: 5.0%-5.4%)]. Factors that were associated with an increased risk of rehospitalization were cancer, liver disease, chronic obstructive pulmonary disease, chronic kidney disease, and immobilization. Patients with PE have a high risk of rehospitalization, with almost half of patients being rehospitalized within 1 year. Identification of high-risk patients may help target interventions aiming at reducing the risk of rehospitalization.

Evaluating the performance of wearable devices for contact tracing in care home environments

COVID-19 has had a devastating impact worldwide, including in care homes where there have been substantial numbers of cases among a very vulnerable population. A key mechanism for managing exposure to the virus and targeting interventions is contact tracing. Unfortunately, environments such as care homes that were most catastrophically impacted by COVID-19 are also those least amenable to traditional contact tracing. A promising alternative to recall and smartphone-based contact tracing approaches is the use of discrete wearable devices that exploit Bluetooth Low Energy (BLE) and Long-Range Wide Area Network (LoRaWAN) technologies. However, the real-world performance of these devices in the context of contact tracing is uncertain. A series of experiments were conducted to evaluate the performance of a wearables system that is based on BLE and LoRaWAN technologies. In each experiment, the number of successful contacts was recorded and the physical distance between two contacts was compared to a calculated distance using the Received Signal Strength Indication (RSSI) to determine the precision, error rate, and duration of proximity. The overall average system contact detection success rate was measured as 75.5%; when wearables were used as per the manufacturer’s guidelines the contact detection success rate increased to 81.5%, but when obstructed by everyday objects such as clothing or inside a bag the contact detection success rate was only 64.2%. The calculated distance using RSSI was close to the physical distance in the absence of obstacles. However, in the presence of typical obstacles found in care home settings, the reliability of detection decreased, and the calculated distance usually appeared far from the actual contact point. The results suggest that under real-world conditions there may be a large proportion of contacts that are underestimated or undetected.

Novel bioinformatic methods and machine learning approaches reveal candidate biomarkers of the intensity and timing of past exposure to Plasmodium falciparum.

Accurately quantifying the burden of malaria over time is an important goal of malaria surveillance efforts and can enable effective targeting and evaluation of interventions. Malaria surveillance methods capture active or recent infections which poses several challenges to achieving malaria surveillance goals. In high transmission settings, asymptomatic infections are common and therefore accurate measurement of malaria burden demands active surveillance; in low transmission regions where infections are rare accurate surveillance requires sampling large subsets of the population; and in any context monitoring malaria burden over time necessitates serial sampling. Antibody responses to Plasmodium falciparum parasites persist after infection and therefore measuring antibodies has the potential to overcome several of the current obstacles to accurate malaria surveillance. Identifying which antibody responses are markers of the timing and intensity of past exposure to P. falciparum remains challenging, particularly among adults who tend to be re-exposed multiple times over the course of their lifetime and therefore have similarly high antibody responses to many Plasmodium antigens. A previous analysis of 479 serum samples from individuals in three regions in southern Africa with different historical levels of P. falciparum malaria transmission (high, intermediate, and low) revealed regional differences in antibody responses to P. falciparum antigens among children under 5 years of age. Using a novel bioinformatic pipeline optimized for protein microarrays that minimizes between-sample technical variation, we used antibody responses to Plasmodium antigens as predictors in random forest models to classify samples from adults into these three regions of differing historical malaria transmission with high accuracy (AUC = 0.99). Many of the most important antigens for classification in these models do not overlap with previously published results and are therefore novel candidate markers for the timing and intensity of past exposure to P. falciparum. Measuring antibody responses to these antigens could lead to improved malaria surveillance.

Contrasting socio-economic influences on colorectal cancer incidence and survival in England and Wales

Colorectal cancer (CRC) is the third most commonly diagnosed cancer in the world and second most common cause of cancer death. The relationship between socio-economic deprivation and CRC incidence is unclear and previous findings have been inconsistent. There is stronger evidence of an association between area-level deprivation and CRC survival; however, few studies have investigated the association between individual-level socio-economic status (SES) and CRC survival.Data from the Office for National Statistics Longitudinal Study (LS) in England and Wales was used. LS members aged 50+ were stratified by individual-level educational attainment, social class, housing tenure and area deprivation quintile, measured at the 2001 Census. Time-to-event analysis examined associations between indicators of SES and CRC incidence and survival (all-cause and CRC death), over a 15-year follow-up period.Among 178116 LS members, incidence of CRC was lower among those with a degree, compared to those with no degree and higher among those employed in manual occupations compared to non-manual occupations. No clear relationship was observed between CRC incidence and the area-based measure of deprivation.Disparities were greater for survival. Among 5016 patients diagnosed with CRC aged 50+, probability of death from all-causes was lower among those with a degree, compared to no degree and higher among those employed in manual occupations, compared to non-manual occupations and among those living in social-rented housing, compared to owner-occupiers. Individual indicators of SES were also associated with probability of death from CRC. Those living in the most deprived areas had a higher probability of death (from all-causes and CRC) compared to those in the least deprived areas.Both individual and area-based indicators of SES were associated with CRC survival, and the relationships were stronger than those observed for CRC incidence. These findings could help inform more effective targeting of public health interventions for CRC.

Spatial Clustering and Risk Factors for Malaria Infections and Marker of Recent Exposure to Plasmodium falciparum from a Household Survey in Artibonite, Haiti.

Targeting malaria interventions in elimination settings where transmission is heterogeneous is essential to ensure the efficient use of resources. Identifying the most important risk factors among persons experiencing a range of exposure can facilitate such targeting. A cross-sectional household survey was conducted in Artibonite, Haiti, to identify and characterize spatial clustering of malaria infections. Household members (N = 21,813) from 6,962 households were surveyed and tested for malaria. An infection was defined as testing positive for Plasmodium falciparum by either a conventional or novel highly sensitive rapid diagnostic test. Seropositivity to the early transcribed membrane protein 5 antigen 1 represented recent exposure to P. falciparum. Clusters were identified using SaTScan. Associations among individual, household, and environmental risk factors for malaria, recent exposure, and living in spatial clusters of these outcomes were evaluated. Malaria infection was detected in 161 individuals (median age: 15 years). Weighted malaria prevalence was low (0.56%; 95% CI: 0.45-0.70%). Serological evidence of recent exposure was detected in 1,134 individuals. Bed net use, household wealth, and elevation were protective, whereas being febrile, over age 5 years, and living in either households with rudimentary wall material or farther from the road increased the odds of malaria. Two predominant overlapping spatial clusters of infection and recent exposure were identified. Individual, household, and environmental risk factors are associated with the odds of individual risk and recent exposure in Artibonite; spatial clusters are primarily associated with household-level risk factors. Findings from serology testing can further strengthen the targeting of interventions.

Identifying barriers to obstructive sleep-disordered breathing care: Parental perspectives.

Despite established clinical practice guidelines for pediatric obstructive sleep-disordered breathing (SDB), disparities persist for this common condition. Few studies have investigated parental experiences about challenges faced in obtaining SDB evaluation and tonsillectomy for their children. To better understand parent-perceived barriers to treatment of childhood SDB, we administered a survey to assess parental knowledge of this condition. A cross-sectional survey was designed to be completed by parents of children diagnosed with SDB. Two validated surveys were administered: 1) Barriers to Care Questionnaire and 2) Obstructive Sleep-Disordered Breathing and Adenotonsillectomy Knowledge Scale for Parents. Logistic regression modeling was performed to assess for predictors of parental barriers to SDB care and knowledge. Eighty parents completed the survey. Mean patient age was 7.4±4.6 years, and 48 (60%) patients were male. The survey response rate was 51%. Patient racial/ethnic categories included 48 (60.0%) non-Hispanic White, 18 (22.5%) non-Hispanic Black, and 14 (17.5%) Other. Parents reported challenges in the 'Pragmatic' domain, including appointment availability and cost of healthcare, as the most frequently described barrier to care. Adjusting for age, sex, race, and education, parents in the middle-income bracket ($26,500 - $79,500) had higher odds of reporting greater barriers to care than parents in the highest (>$79,500) income tier (OR 5.536, 95% CI 1.312-23.359, P=0.020) and lowest income tier (<$26,500) (OR 3.920, 95% CI 1.096-14.020). Parents whose children had tonsillectomy (n=40) answered only a mean 55.7%±13.3% of questions correctly on the knowledge scale. Pragmatic challenges were the most encountered barrier that parents reported in accessing SDB care. Families in the middle-income tier experienced the greatest barriers to SDB care compared to lower and higher income families. In general, parental knowledge of SDB and tonsillectomy was relatively low. These findings represent potential areas of improvement to target interventions to promote equitable care for SDB.

Evaluating COVID-19 Risk to Essential Workers by Occupational Group: A Case Study in Massachusetts

Occupational exposure to SARS-CoV-2 varies by profession, but “essential workers” are often considered in aggregate in COVID-19 models. This aggregation complicates efforts to understand risks to specific types of workers or industries and target interventions, specifically towards non-healthcare workers. We used census tract-resolution American Community Survey data to develop novel essential worker categories among the occupations designated as COVID-19 Essential Services in Massachusetts. Census tract-resolution COVID-19 cases and deaths were provided by the Massachusetts Department of Public Health. We evaluated the association between essential worker categories and cases and deaths over two phases of the pandemic from March 2020 to February 2021 using adjusted mixed-effects negative binomial regression, controlling for other sociodemographic risk factors. We observed elevated COVID-19 case incidence in census tracts in the highest tertile of workers in construction/transportation/buildings maintenance (Phase 1: IRR 1.32 [95% CI 1.22, 1.42]; Phase 2: IRR: 1.19 [1.13, 1.25]), production (Phase 1: IRR: 1.23 [1.15, 1.33]; Phase 2: 1.18 [1.12, 1.24]), and public-facing sales and services occupations (Phase 1: IRR: 1.14 [1.07, 1.21]; Phase 2: IRR: 1.10 [1.06, 1.15]). We found reduced case incidence associated with greater percentage of essential workers able to work from home (Phase 1: IRR: 0.85 [0.78, 0.94]; Phase 2: IRR: 0.83 [0.77, 0.88]). Similar trends exist in the associations between essential worker categories and deaths, though attenuated. Estimating industry-specific risk for essential workers is important in targeting interventions for COVID-19 and other diseases and our categories provide a reproducible and straightforward way to support such efforts.

Role of cGAS-STING signaling pathway in cardiometabolic diseases.

Cardiometabolic disease is a common clinical syndrome with exact causal relationship between the aberrant of glucose/lipid metabolism and cardiovascular disfunction, but its pathogenesis is unclear. Cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS)-stimulator of interferon gene (STING) signaling pathway regulates the activation of innate immunity by sensing intracellular double stranded DNA. Metabolic risk factors drive the activation of cGAS-STING pathway through mitochondrial DNA, nuclear DNA and endoplasmic reticulum stress. In addition, the activation of the cGAS-STING pathway triggers chronic sterile inflammation, excessive activation of autophagy, senescence and apoptosis in related cells of cardiovascular system. These changes induced by cGAS-STING pathway might be implicated in the onset and deterioration of cardiometabolic disease. Therefore, the targeting intervention of cGAS-STING signaling pathway may emerge as a novel treatment for cardiometabolic disease.

Recent Advances in Clinical Research for Skin Cancer Chemoprevention.

Neoplasm arising from the keratinocytes or melanocytes in the skin is the most prevalent type of cancer in the United States and worldwide. Since ultraviolet (UV) radiation may be a causing factor for several types of skin cancer, effective strategies to manage skin cancer include preventive measures such as minimizing exposure to UV and applying sunscreens. However, the effect of sunscreen in reducing skin cancer incidence remains uncertain. An alternative approach to prevent skin cancer is chemoprevention, which is defined as using either natural products or synthetic compounds to inhibit, delay, or reverse the development of cancer. Preclinical studies have demonstrated the effectiveness of multiple pharmacological agents and dietary supplements. However, whether preclinical findings can be translated into clinical application is unknown. This review evaluates the state of recent clinical trials investigating chemopreventive agents focusing on skin cancer to compare the target populations, interventions, endpoints, and outcomes of these trials. The ClinicalTrials and PubMed databases were searched for their available literature using the key words "skin cancer" and "chemoprevention". The objective of this review is to provide updated information on the effectiveness and side effects of promising chemopreventive agents in human subjects and to identify research gaps.

The Impact of the Local Climate on the level of Violence at School Among Youth in the Arab sector in Israel

This dissertation examined the impact of the local climate on the level of violence at school among youth in the Arab sector in Israel. Given the lack of research on this topic, the current study sought to fill this gap in the literature. The study used a mixed-methods approach, incorporating both quantitative and qualitative data. The quantitative data was collected through a survey of Arab youth in Israel. The qualitative data was collected through in-depth interviews with a small sub-sample of the survey participants. The study sought to answer the following question: What factors are associated with increased levels of violence at school among Arab youth living in Israel? The findings of the study will provide policymakers and educators with useful information about the nature and extent of violence among Arab youth, which may help to identify and address risk factors. By understanding the factors that contribute to violence at school among Arab youth, policymakers and educators can better target interventions that will have the most impact. For example, interventions that address socio-economic factors may be more successful in reducing violence if they are implemented in a community where violence is prevalent. In addition, programs designed to reduce violence at school may be more effective if they are tailored specifically to the needs of Arab youth. The results of the study suggest that the local climate has a significant impact on the level of violence at school among youth in the Arab sector of Israel. Specifically, the study found that higher temperatures and humidity levels are associated with an increase in the frequency and severity of violent incidents. The study also found that students who live in areas with a higher prevalence of violence are more likely to engage in violent behavior themselves. There are a number of potential interventions that could be used to improve the situation for Arab youth in Israel. For example, providing access to mental health services and counseling could help address the psychological factors that contribute to violent behavior among some students. Another potential intervention is to improve the quality of education in the Arab sector of Israel, which has historically been underfunded and understaffed. Addressing issues such as overcrowding, a lack of resources, and inadequate teacher training could go a long way in improving the overall educational experience for Arab youth, and may also help reduce incidents of violence at school.
