Primary aromatic amines (PAAs) are a class of hazardous substances where many compounds are classified as carcinogen, mutagen, and reproduction toxin (CMR). PAAs can be taken up by dermal exposure. In the polyurethane industry, a valid and trustworthy method for the quantification of PAAs in the presence of isocyanates that could interfere is of great interest, especially on workplaces where a regular contact to PAAs cannot be excluded. The aim of this work is the development, validation, and verification of a novel sampling device to quantify selectively the PAA load on work surfaces. We describe the synthesis of Cell-ßALA-PEMSA analytical papers and their characterization by infrared spectroscopy and thermogravimetric analysis. The recovery of TDA and MDA spiked on these filters is satisfactory. An excellent selectivity of Cell-ßALA-PEMSA papers towards PAAs in the presence of isocyanates of almost 100% was found by wipe tests of amine/isocyanate contaminated surfaces. First positive field tests were achieved at certain areas in a Polyurethane Technical Application Department where surface contamination with PAAs was expected, and the Cell-ßALA-PEMSA analytical papers were superior to an established method of surface sampling. However, recovery of these amines from surfaces shows a large variability, and more work is required to address influencing surface properties. [ABSTRACT FROM AUTHOR]

Background Previous meta-analyses have indicated that aspirin could affect breast cancer outcomes, particularly when taken post-diagnostically. However, several recent studies appear to show little to no association between aspirin use and breast cancer mortality, all-cause mortality, or recurrence. Aims This study aims to conduct an updated systematic review and meta-analysis on the associations of pre-diagnostic and post-diagnostic aspirin use with the aforementioned breast cancer outcomes. It also looks, through subgroup analyses and meta-regressions, at a range of variables that could explain the associations between aspirin use and breast cancer outcomes. Results In total, 24 papers and 149 860 patients with breast cancer were included. Pre-diagnostic aspirin use was not associated with breast-cancer-specific mortality (HR 0.98, 95% CI, 0.80-1.20, P =.84) or recurrence (HR 0.94, 95% CI, 0.88-1.02, P =.13). Pre-diagnostic aspirin was associated with non-significantly higher all-cause mortality (HR 1.27, 95% CI, 0.95-1.72, P =.11). Post-diagnostic aspirin was not significantly associated with all-cause mortality (HR 0.87, 95% CI, 0.71-1.07, P =.18) or recurrence (HR 0.89, 95% CI, 0.67-1.16, P =.38). Post-diagnostic aspirin use was significantly associated with lower breast-cancer-specific mortality (HR 0.79, 95% CI, 0.64-0.98, P =.032). Conclusions The only significant association of aspirin with breast cancer outcomes is lower breast-cancer-specific mortality in patients who used aspirin post-diagnostically. However, factors such as selection bias and high inter-study heterogeneity mean that this result should not be treated as conclusive, and more substantial evidence such as that provided by RCTs is needed before any decisions on new clinical uses for aspirin should be made.

Intersectoral collaborations are recommended as effective strategies to reduce health inequalities. People most affected by health inequalities, as are people living in poverty, remain generally absent from such intersectoral collaborations. Community-based participatory research (CBPR) projects can be leveraged to better understand how to involve people with lived experience to support both individual and community empowerment. In this paper, we offer a critical reflection on a CBPR project conducted in public housing in Québec, Canada, that aimed to develop intersectoral collaboration between tenants and senior executives from four sectors (housing, health, city and community organizations). This single qualitative case study design consisted of fieldwork documents, observations and semi-structured interviews. Using the Emancipatory Power Framework (EPF) and the Limiting Power Framework (LPF), we describe examples of types of power and resistance shown by the tenants, the intersectoral partners and the research team. The discussion presents lessons learned through the study, including the importance for research teams to reflect on their own power, especially when aiming to reduce health inequalities. The paper concludes by describing the limitations of the analyses conducted through the EPF–LPF frameworks and suggestions to increase the transformative power of future studies.

Community structure over social media (SM) is the collaborative group of globally spread users with identical characteristics and ideologies. The collective features of SM are inherent with both the implicit and explicit nature of end-users. This paper presents an analytical and methodological community detection framework to bind passive users' implicit and explicit nature after scrutinizing graphical data to identify seed nodes and communities. Moreover, this work provides the concept of the unsupervised machine learning approach over the graphical perspective of SM to identify the trade-off between similarity of nodes attributes and density of connections for social theories. Subsequently, this paper evaluates a comprehensive analysis of the benchmark community detection algorithm (CDA) Label Propagation Algorithm (LPA), Clique Percolation Method (CPM), Democratic Estimate of the Modular Organization of a Network (DEMON) and Non-Negative Matrix Factorization (NMF). The evaluation has been carried out over modularity and normalized mutual information of resultant structured community on six real-time SM data set. The performance of benchmark CDAs is significantly increased after incorporating social theories. NMF, DEMON, CPM and LPA gained the highest improvement over Zachary's Karate Club data sets, i.e. approximate 26.91%, 21.68%, 18.79%, 19.96%, respectively. [ABSTRACT FROM AUTHOR]

Social work in the twenty-first century is maturing as a global profession. This comparative study offers an original contribution to the evolving discussion in the field of international social work. The paper makes visible the socio-spatial dimensions and contested interpretations of international and indigenous knowledge through the experiences of social work students in the Global South and Global North. Drawing on findings from an online survey completed by undergraduate and postgraduate Nigerian and Scottish social work students (n  = 142), the paper provides insights into the students' experiences, expectations and perceived challenges. The Nigerian students critiqued the international (Western) knowledge informing their learning and practice, questioned the absence of indigenous knowledge and were aware of the importance, and challenges, of working with cultural diversity. The Scottish students showed little criticality of the Western (local) knowledge underpinning their learning and practice, did not prioritise learning about international social work and highlighted tensions between working with a culture of neoliberalism and social work values and social justice. We call for raising awareness of the epistemological foundations of what is included/excluded in curriculum and why, making the 'local' visible through re-balancing and contextualising the use of international and indigenous knowledge within social work.

Low-frequency seismic data plays a crucial role in seismic data processing and seismic wave inversion. At present, there are two methods to realize the low-frequency excitation of vibrators: one is exciting low-frequency vibrators by linear sweep signals, and the other is exciting conventional vibrators by nonlinear low-frequency sweep signals. The cost of exploration using low-frequency vibroseis is high, and it is challenging to obtain sufficient low-frequency information using traditional vibrators. To this end, this paper comparatively studies the low-frequency sweep signal characteristics and data effects of low-frequency and traditional vibrators. Therefore, three kinds of linear and nonlinear low-frequency sweep signal are designed. Theoretical analysis shows that there are certain differences between linear and nonlinear signal in design methods, signal shapes, etc. but after correlation calculations the signal spectra reflecting the seismic response and the related wavelet shapes are basically consistent. Besides, the actual force signal data shows that the linear and nonlinear harmonic distortion are basically equivalent. Finally, based on the forward simulation of three sweep signals and the comparative analysis of field test data, it can be considered that the linear and nonlinear low-frequency sweep signals of vibrators have almost the same denoising ability under the basic conditions of the spectrum and wavelet. Both can achieve low-frequency excitation and obtain rich low-frequency information, and the quality of seismic data is basically the same, so they can be applied in practical production.

During the early years following Ghana's political independence from British rule, calls were made for university education to have 'an African character'. As a field steeped in Eurocentric narratives, how did the Classics survive, and how did classicists respond to the politics of Africanization? This paper draws on the political contexts under which secondary and tertiary education in Ghana underwent reforms to discuss the threats and challenges these reforms posed to the sustenance of the field of Classics, and the decolonization strategies classicists adopted during the calls for Africanization in university education. The paper suggests that the idea of 'world civilization' which does not consider one civilization as superior over another cemented decolonization efforts in the early post-independent era, and helped classicists meet the conditions of 'relevance' in the African context through comparative studies. Current attempts at decolonizing Classics in Africa would benefit from these strategies if applied to both research and curriculum development. [ABSTRACT FROM AUTHOR]

There are various research designs and approaches to investigate how health-promoting activities are implemented in complex, real-world systems, and to identify potential health effects that might occur following implementation. Although literature describes guidelines to perform and report about implementation research and effect evaluations, no specific guidelines exist on analysing and reporting about the combination of effectiveness data and implementation data collected as part of intervention evaluation in complex and diverse settings. This paper describes the evaluation of primary school-based health-promoting activities in complex systems. Furthermore, an approach for data categorization inspired by Rogers' Diffusion of Innovations theory is presented that can facilitate structuring the study's results and relating the degree of implementation to any impact on effectiveness outcomes that might be observed. Researchers interested in using this approach for data categorization have to ensure that the following three conditions are met: (i) data on an intervention's efficacy in a controlled setting with optimal implementation is available; (ii) key points that define an intervention's optimal implementation are available and (iii) an evaluation study is performed, collecting both effectiveness data and implementation data in a real-world context. This data categorization approach can be useful to generate more insight into an intervention's effectiveness under varying circumstances, and optimal support and advice can be provided to stakeholders to achieve maximum impact of population-based health-promoting interventions in complex, real-world systems. However, the proposed approach is a first suggestion and further testing and adaptation is necessary to increase its usefulness. Knowledge and experience sharing among researchers performing comparable research can increase the knowledge base regarding this subject. [ABSTRACT FROM AUTHOR]

The incidence of many hormone-dependent diseases, including testicular cancer, has sharply increased in all high-income countries during the 20th century. This is not fully explained by established risk factors. Concurrent, increasing exposure to antiandrogenic environmental endocrine disrupting chemicals (EDCs) in fetal life may partially explain this trend. This systematic review assessed available evidence regarding the association between environmental EDC exposure and risk of testicular cancer (seminomas and nonseminomas). Following PRISMA guidelines, a search of English peer-reviewed literature published prior to December 14, 2020 in the databases PubMed and Embase® was performed. Among the 279 identified records, 19 were eligible for quality assessment and 10 for further meta-analysis. The completeness of reporting was high across papers, but over 50% were considered subject to potential risk of bias. Mean age at diagnosis was 31.9 years. None considered effects of EDC multipollutant mixtures. The meta-analyses showed that maternal exposure to combined EDCs was associated with a higher risk of testicular cancer in male offspring [summary risk ratios: 2.16, (95% CI:1.78-2.62), 1.93 (95% CI:1.49-2.48), and 2.78 (95% CI:2.27-3.41) for all, seminoma, and nonseminoma, respectively]. Similarly, high maternal exposures to grouped organochlorines and organohalogens were associated with higher risk of seminoma and nonseminoma in the offspring. Summary estimates related to postnatal adult male EDC exposures were inconsistent. Maternal, but not postnatal adult male, EDC exposures were consistently associated with a higher risk of testicular cancer, particularly risk of nonseminomas. However, the quality of studies was mixed, and considering the fields complexity, more prospective studies of prenatal EDC multipollutant mixture exposures and testicular cancer are needed.

Aims: Most patients who receive implantable cardioverter defibrillators (ICDs) for primary prevention do not receive therapy during the lifespan of the ICD, whilst up to 50% of sudden cardiac death (SCD) occur in individuals who are considered low risk by conventional criteria. Machine learning offers a novel approach to risk stratification for ICD assignment.Methods and Results: Systematic search was performed in MEDLINE, Embase, Emcare, CINAHL, Cochrane Library, OpenGrey, MedrXiv, arXiv, Scopus, and Web of Science. Studies modelling SCD risk prediction within days to years using machine learning were eligible for inclusion. Transparency and quality of reporting (TRIPOD) and risk of bias (PROBAST) were assessed. A total of 4356 studies were screened with 11 meeting the inclusion criteria with heterogeneous populations, methods, and outcome measures preventing meta-analysis. The study size ranged from 122 to 124 097 participants. Input data sources included demographic, clinical, electrocardiogram, electrophysiological, imaging, and genetic data ranging from 4 to 72 variables per model. The most common outcome metric reported was the area under the receiver operator characteristic (n = 7) ranging between 0.71 and 0.96. In six studies comparing machine learning models and regression, machine learning improved performance in five. No studies adhered to a reporting standard. Five of the papers were at high risk of bias.Conclusion: Machine learning for SCD prediction has been under-applied and incorrectly implemented but is ripe for future investigation. It may have some incremental utility in predicting SCD over traditional models. The development of reporting standards for machine learning is required to improve the quality of evidence reporting in the field. [ABSTRACT FROM AUTHOR]

Background and Objectives Population aging has led to an increased interest in cognitive health and, in particular, the role that stress plays in cognitive disparities. This paper extends previous work by characterizing coronavirus disease 2019 (COVID-19) stress type prevalence and its association with cognitive health in metro-Detroit among Black, Middle Eastern/Arab (MENA), and White older adults. Research Design and Methods Data come from a regionally representative sample of adults aged 65+ in metro-Detroit (N = 600; MENA n = 199; Black n = 205; White n = 196). We used generalized linear models to compare groups on sociodemographic, objective stress, and social stress indicators. Multiple group structural equation models evaluated whether COVID-19 stress predicted cognitive health and whether that association varied across racial/ethnic groups. Results MENA and Black older adults reported higher levels of objective stress than Whites. There were no racial/ethnic group differences in social stress. More objective stress was associated with better cognitive health, and more social stress was associated with worse cognitive health. The positive effect of objective stress was especially apparent for White older adults. Discussion and Implications Though it appears that minority stress was not exacerbated in the context of pandemic stress, links between greater objective stress and better cognitive health apparent among White older adults were not evident among MENA or Black older adults. Broadening health disparities research by including underrepresented populations allows us to elevate scientific knowledge by clarifying what is universal and what is unique about the stress process.

Aims Heart failure nurse practitioners (HF NPs) are an emerging component of the heart failure (HF) specialist workforce but their impact in an inpatient setting is untested. The aim of this paper is to explore the impact of an inpatient HF NP service on 12- month all-cause rehospitalizations, emergency department (ED) presentations, and mortality in patients hospitalized with HF compared with usual hospital care. Methods and results Retrospective, two-group comparative design involving patients (n= 408) admitted via ED with acute HF to a metropolitan quaternary hospital between January 2013 and August 2017. Doubly robust estimation with augmented inverse probability weighting (DR-AIPW) was used to account for the non-random allocation of patients to usual hospital care or the HF NP service in addition to usual in-hospital care. Among 408 patients (186 usual care and 222 HF NP service) admitted with acute HF, the mean age was 76.5 [standard deviation (SD) 12.0] years and 56.4% (n=230) were male. After IPW adjustment, patients seen by the HF NP service had a lower risk of 12-month rehospitalization (61.3 vs. 78.3% usual care; difference -16.9%, 95% CI: -26.4%, -6.6%) and ED presentations (12.6 vs. 22.0%; difference -9.4%, 95% CI: -17.3%, -1.4%) with no difference in 6- or 12-month mortality. The HF NP service improved referrals to a home visiting programme that was available to HF patients (64.4 vs. 45.4%; difference 19%, 95% CI: 8.8%, 28.8%). Conclusion Additional support by an inpatient HF NP service has the potential to significantly reduce rehospitalizations and ED presentations over 12 months. Further evidence from a multicentre randomized control trial is warranted. [ABSTRACT FROM AUTHOR]

In sub-Saharan Africa (SSA), cervical cancer (CC) is the second leading cause of cancer-related deaths, with human immunodeficiency virus (HIV) seropositive women being particularly vulnerable. Despite the benefits of early CC screening in reducing HIV-related CC deaths, CC screening uptake remains limited, with wide disparities in access across SSA. As part of a larger study, this paper examines the determinants of CC screening among HIV-seropositive women of reproductive age (15–49 years) in Zimbabwe. Using the 2015 Zimbabwe Demographic and Health Survey, we conducted multilevel analyses of CC screening among 1490 HIV-seropositive women, nested in 400 clusters. Our findings revealed that, even though 74% of HIV-seropositive women knew about CC, only 17.6% of them reported ever screening for it. Women who held misconceptions about HIV (OR = 0.47, p = 0.01) were less likely to screen for CC compared to those with accurate knowledge about HIV and CC. HIV-seropositive women with secondary or higher education were more likely to screen (OR = 1.39, p = 0.04) for CC compared to those with a primary or lower level of education. Age was positively associated with screening for CC. Furthermore, locational factors, including province and rural–urban residence, were associated with CC screening. Based on these findings, we call for integrated care and management of HIV and non-communicable diseases in Southern Africa, specifically, Zimbabwe due to the legacy of HIV in the region.

Objectives: To assess the quality of evidence on the effectiveness of local US laws restricting the sale of flavored tobacco products.Methods: We conducted a systematic search and qualitative scoping review of English-language papers published through May 2020 that evaluated flavored tobacco sales policies implemented by US jurisdictions during 2010-2019. We constructed a conceptual model for flavored and menthol tobacco sales restriction outcomes, assigned GRADE quality of evidence ratings to policy outcomes evaluated through the included studies, and summarized factors that might explain weak or inconsistent findings.Results: We found moderate to high quality of evidence associating policy implementation with reduced availability, marketing, and sales of policy-restricted products, and decreased youth and adult tobacco use of these products; however, policy exclusions and exemptions, implementation challenges, tobacco industry actions (e.g., marketing of concept-named flavored products; exploiting policy exemptions for certain store types), and consumer responses (e.g., cross-border or illicit purchasing) might undermine or mitigate intended policy effects.Conclusions: Flavored and menthol tobacco product sales restrictions implemented and evaluated in US jurisdictions appear to have achieved some of their intended outcomes; however, deficiencies in study designs, methods, and metrics could contribute to equivocal findings on quality of evidence associating policy implementation and outcomes. Gaps in the evidence are beginning to be filled with research using more rigorous study designs, improved measurement and analytic methods, and longer-term follow-up.Implications: In the absence of comprehensive federal action, US jurisdictions have the obligation to restrict flavored and menthol product sales to protect vulnerable populations from tobacco-related harms. The considerable expenditure of financial resources, political will, and time dedicated to policy adoption and implementation argue for evaluation studies designed to maximize the quality of evidence. This review offers generalizable insights into evaluation findings that can inform efforts to enhance tobacco control policy implementation and impact in the US and globally. [ABSTRACT FROM AUTHOR]

Priority setting represents an even bigger challenge during public health emergencies than routine times. This is because such emergencies compete with routine programmes for the available health resources, strain health systems and shift health-care attention and resources towards containing the spread of the epidemic and treating those that fall seriously ill. This paper is part of a larger global study, the aim of which is to evaluate the degree to which national COVID-19 preparedness and response plans incorporated priority setting concepts. It provides important insights into what and how priority decisions were made in the context of a pandemic. Specifically, with a focus on a sample of 18 African countries' pandemic plans, the paper aims to: (1) explore the degree to which the documented priority setting processes adhere to established quality indicators of effective priority setting and (2) examine if there is a relationship between the number of quality indicators present in the pandemic plans and the country's economic context, health system and prior experiences with disease outbreaks. All the reviewed plans contained some aspects of expected priority setting processes but none of the national plans addressed all quality parameters. Most of the parameters were mentioned by less than 10 of the 18 country plans reviewed, and several plans identified one or two aspects of fair priority setting processes. Very few plans identified equity as a criterion for priority setting. Since the parameters are relevant to the quality of priority setting that is implemented during public health emergencies and most of the countries have pre-existing pandemic plans; it would be advisable that, for the future (if not already happening), countries consider priority setting as a critical part of their routine health emergency and disease outbreak plans. Such an approach would ensure that priority setting is integral to pandemic planning, response and recovery. [ABSTRACT FROM AUTHOR]

Family group conferences (FGCs) in child welfare share decision-making with family members by bringing the immediate and wider family together to make a plan to meet a child's needs. This paper reports survey findings on FGC provision in the UK in 2022 and explores whether in England the presence of an FGC service and the rate of FGC provision is associated with the rate of children in care, entering care, in kinship foster care and leaving care. Seventy-nine per cent (n  = 167) of local authorities in the UK provided FGCs to families, and 14 per cent (n  = 29) did not. Services that were more established offered a more diverse range of FGCs. The introduction of FGCs in English local authorities was associated with a higher rate of children in care, but also higher rates of kinship foster care, a key goal of FGCs where it is not possible for children to stay with their parents. Higher rates of FGCs were associated with more children leaving care, possibly due to reunification with birth families. To understand in more detail, the circumstances of children in and leaving care in local authorities with FGCs, individual data linkage studies are needed. [ABSTRACT FROM AUTHOR]

The popularity of social networks turns them into a legal method for promoting a healthy lifestyle, which benefits not only people but also different countries' governments. This research paper aimed to examine the Keep fitness app integrated into WeChat, Weibo and QQ as regards long-term improvements in health-related behaviors (physical activity, nutrition, health responsibility, spiritual growth, interpersonal relationships and stress management) and assess the associated risk of increased social media addiction. Students from Lishui University in China (N  = 300) participated in this study, and they were formed into control and experimental groups. The Healthy Lifestyle Behavior Scale and Social Media Disorder Scale were used as psychometric instruments. The Keep app was found to improve respondents' scores on the parameters of physical activity, nutrition and health responsibility (P  = 0.00). However, the level of dependence on social media did not change in either the control or the experimental group during the year of research (P  ≥ 0.05). It is concluded that fitness apps can be an effective tool to promote healthy lifestyles among young people in China and other countries. The feasibility of government investment in fitness apps to promote healthy lifestyles is substantiated. [ABSTRACT FROM AUTHOR]

The rise of exclusionary populism is widely regarded as one of the most significant phenomena in today's political world. Despite this, the relationship between populism and security remains under-explored in the literature, including the affective power of populist security narratives. Against this background, this paper conducts a comparative analysis of radical right populist discourse in response to two recent shocking crimes in France and Ireland. The different expression given to security concerns in the two countries, such as a much less antagonistic 'flaunting of the low' in France, is suggestive of a more contingent and institutionally mediated relationship between security and populism than the existing literature would suggest.

In this paper, we present a practical approach for computing the sandwich variance estimator in 2-stage regression model settings. As a motivating example for 2-stage regression, we consider regression calibration, a popular approach for addressing covariate measurement error. The sandwich variance approach has rarely been applied in regression calibration, despite its requiring less computation time than popular resampling approaches for variance estimation, specifically the bootstrap. This is probably because it requires specialized statistical coding. Here we first outline the steps needed to compute the sandwich variance estimator. We then develop a convenient method of computation in R for sandwich variance estimation, which leverages standard regression model outputs and existing R functions and can be applied in the case of a simple random sample or complex survey design. We use a simulation study to compare the sandwich estimator to a resampling variance approach for both settings. Finally, we further compare these 2 variance estimation approaches in data examples from the Women's Health Initiative (1993–2005) and the Hispanic Community Health Study/Study of Latinos (2008–2011). In our simulations, the sandwich variance estimator typically had good numerical performance, but simple Wald bootstrap confidence intervals were unstable or overcovered in certain settings, particularly when there was high correlation between covariates or large measurement error.

Aims The outbreak of COVID-19 was potentially stressful for everyone and possibly heightened in those having surgery. We sought to explore the impact of the pandemic on recovery from cardiac surgery. Methods and results A prospective observational study of 196 patients who were ≥18years old undergoing cardiac surgery between March 23 and July 4, 2020 (UK lockdown) was conducted. Those too unwell or unable to give consent/complete the questionnaires were excluded. Participants completed (on paper or electronically) the impact of event [Impact of Events Scale-revised (IES-R)] (distress related to COVID-19), depression [Centre for Epidemiological Studies Depression Scale (CES-D)], and EQ-5D-5L [(quality of life, health-related quality of life (HRQoL)] questionnaires at baseline, 1 week after hospital discharge, and 6 weeks, 6 months and 1 year post-surgery. Questionnaire completion was >75.0% at all timepoints, except at 1 week (67.3%). Most participants were male [147 (75.0%)], white British [156 (79.6%)] with an average age 63.4years. No patients had COVID-19. IES-R sand CES-D were above average at baseline (indicating higher levels of anxiety and depression) decreasing over time. HRQoL pre-surgery was high, reducing at 1 week but increasing to almost pre-operative levels at 6 weeks and exceeding pre-operative levels at 6 months and 1 year. IES-R and CES-D scores were consistently higher in women and younger patients with women also having poorer HRQoL up to 1-year after surgery. Conclusions High levels of distress were observed in patients undergoing cardiac surgery during the COVID-19 pandemic with women and younger participants particularly affected. Psychological support pre- and post-operatively in further crises or traumatic times should be considered to aid recovery. Registration Clinicaltrials.gov ID:NCT04366167. [ABSTRACT FROM AUTHOR]

The paper aims to add to the debate on the varieties of neoliberalism and the homogenizing effects of megaproject-based urban development. It examines the acculturation of the growth imperative as the master discourse that supports the development and implementation of two projects aimed at transforming the centers of Tampere, Finland, and Ł 'od'z, Poland. The selected cities shared similar traits as industrial centers in the past, but their current socioeconomic situation is entirely different. Tampere holds the title of "Finland's most likeable city," while rapidly depopulating Ł 'od'z was labeled the "Polish Detroit." Nevertheless, both municipalities became attracted by the idea of boosting their development through implementing large-scale infrastructural investments to reshape their centers. Inspired by discursive institutionalism, which defines discourse as a set of policy ideas and values, and interactive policy communication and formulation processes, the paper reconstructs and compares the strategic visions of Tampere's "Five Star City Centre" and "The New Centre of Ł 'od'z." It demonstrates how the proponents of the projects discursively forced consent around proposed ideas. Namely, it shows how the issues of complexity, risk, and potential conflict of the two megaprojects have been addressed. On a conceptual level, the paper shows how policy convergence can be discursively facilitated in different socioeconomic, cultural, and political circumstances. [ABSTRACT FROM AUTHOR]

Background: Rigorously designed longitudinal studies can inform how best to reduce the widening health gap between Indigenous and non-Indigenous children.Methods: A systematic review was performed to identify and present the breadth and depth of longitudinal studies reporting the health and well-being of Indigenous children (aged 0-18 years) globally. Databases were searched up to 23 June 2020. Study characteristics were mapped according to domains of the life course model of health. Risk of bias was assessed using the National Institutes of Health (NIH) Study Quality Assessment Tools. Reported level of Indigenous involvement was also appraised; PROSPERO registration CRD42018089950.Results: From 5545 citations, 380 eligible papers were included for analysis, representing 210 individual studies. Of these, 41% were located in Australia (n = 88), 22.8% in the USA (n = 42), 11.9% in Canada (n = 25) and 10.9% in New Zealand (n = 23). Research tended to focus on either health outcomes (50.9%) or health-risk exposures (43.8%); 55% of studies were graded as 'good' quality; and 89% of studies made at least one reference to the involvement of Indigenous peoples over the course of their research.Conclusions: We identified gaps in the longitudinal assessment of cultural factors influencing Indigenous child health at the macrosocial level, including connection to culture and country, intergenerational trauma, and racism or discrimination. Future longitudinal research needs to be conducted with strong Indigenous leadership and participation including holistic concepts of health. This is critical if we are to better understand the systematic factors driving health inequities experienced by Indigenous children globally. [ABSTRACT FROM AUTHOR]

In diagnostic medicine, the true disease status of a patient is often represented on an ordinal scale—for example, cancer stage (0, I, II, III, or IV) or coronary artery disease severity measured using the Coronary Artery Disease Reporting and Data System (CAD-RADS) scale (none, minimal, mild, moderate, severe, or occluded). With advances in quantitation of diagnostic images and in artificial intelligence (AI), both supervised and unsupervised algorithms are being developed to help physicians correctly grade disease. Most of the diagnostic accuracy literature deals with binary disease status (disease present or absent); however, tests diagnosing ordinal-scaled diseases should not be reduced to a binary status just to simplify diagnostic accuracy testing. In this paper, we propose different characterizations of ordinal-scale accuracy for different clinical use scenarios, along with methods for comparing tests. In the simplest scenario, just the proportion of correct grades is considered; other scenarios address the magnitude and direction of misgrading; and at the other extreme, a weighted accuracy measure with weights based on the relative costs of different types of misgrading is presented. The various scenarios are illustrated using a coronary artery disease example where the accuracy of AI algorithms in providing patients with the correct CAD-RADS grade is assessed.

Background Recent studies suggest that metformin use may be associated with improved infectious disease–related outcomes, whereas other papers suggest potentially worse outcomes in serious bacterial infections. Our purpose was to examine the association of prior outpatient prescription of metformin on 30- and 90-day mortality for older veterans with pre-existing diabetes hospitalized with pneumonia. Methods We conducted a retrospective cohort study using national Department of Veterans Affairs data of patients ≥65 years with a prior history of diabetes who were hospitalized with pneumonia over a 10-year period (fiscal years 2002–2012.) For our primary analysis, we created a propensity score and matched metformin users to nonusers 1:1. Results We identified 34 759 patients who met the inclusion criteria, 20.3% of whom were prescribed metformin. Unadjusted 30-day mortality was 9.6% for those who received metformin versus 13.9% in nonusers (P <.003), and 90-day mortality was 15.8% for those who received metformin versus 23.0% for nonusers (P <.0001). For the propensity score model, we matched 6899 metformin users to 6899 nonusers. After propensity matching, both 30-day (relative risk [RR]:.86; 95% confidence interval [CI]:.78–.95) and 90-day (RR:.85; 95% CI:.79–.92) mortality was significantly lower for metformin users. Conclusions Prior receipt of metformin was associated with significantly lower mortality after adjusting for potential confounders. Additional research is needed to examine the safety and potential benefits of metformin use in patients with respiratory infections. [ABSTRACT FROM AUTHOR]

There are communities in which hearing voices frequently is common and expected, and in which participants are not expected to have a need for care. This paper compares the ideas and practices of these communities. We observe that these communities utilize cultural models to identify and to explain voice-like events—and that there are some common features to these models across communities. All communities teach participants to "discern," or identify accurately, the legitimate voice of the spirit or being who speaks. We also observe that there are roughly two methods taught to participants to enable them to experience spirits (or other invisible beings): trained attention to inner experience, and repeated speech to the invisible other. We also observe that all of these communities model a learning process in which the ability to hear spirit (or invisible others) becomes more skilled with practice, and in which what they hear becomes clearer over time. Practice—including the practice of discernment—is presumed to change experience. We also note that despite these shared cultural ideas and practices, there is considerable individual variation in experience—some of which may reflect psychotic process, and some perhaps not. We suggest that voice-like events in this context may be shaped by cognitive expectation and trained practice as well as an experiential pathway. We also suggest that researchers could explore these common features both as a way to help those struggling with psychosis, and to consider the possibility that expectations and practice may affect the voice-hearing experience.

In this paper, we put forward two novel arguments against the counterfactual comparative account (CCA) of harm and benefit. In both arguments, the central theme is that CCA conflicts with plausible judgements about benefit and prudence. [ABSTRACT FROM AUTHOR]

To support student learning about clinical music therapy termination processes, a qualitative research method was used to address three research questions: (a) What are the current termination practices of music therapists from multiple clinical settings? (b) What types of termination practices might they describe? and (c) What processes do they move through in their termination practices? Forty-six music therapists were interviewed about their experiences of clinical termination in music therapy. They described 134 termination scenarios that took place in 18 different types of clinical settings. Inductive thematic analysis of the scenarios identified several themes, one of which is addressed in this paper: termination types. Nine types of termination processes are described in the results. The types were described using the salient features of the termination scenarios. Identifying termination types in this way has the potential to provide students and clinicians with ways to think critically and creatively about what it means to effectively terminate a therapeutic relationship and about what effective termination can look like in different clinical settings.

Human capital accumulation is a key driver of economic development across countries. Although previous studies have shown that country-specific circumstances (e.g., cultural, health-related, and educational factors) are strongly related with the accumulation of human capital in society, few studies have explored the importance of innate ability factors in general and ADHD-related behavioral symptoms in particular for cognitive skill outcomes. This paper hypothesizes and empirically establishes the educational burden of the ADHD-related behavioral symptoms on aggregate cognitive achievement outcomes. We use a novel compilation of the 2- and 7-repeat allele variants of the human DRD4 exon III gene that candidate gene association studies have identified as an important biomarker in the etiology of childhood ADHD. We find that our indicator for the prevalence of ADHD genetic risk in society has a negative and statistically significant impact on educational achievement. Additional sensitivity tests and estimation methods further corroborate our main hypothesis. [ABSTRACT FROM AUTHOR]

Shiftwork leads to myriad negative health and safety outcomes. Lighting countermeasures can benefit shiftworkers via physiological effects of light (e.g. alerting, circadian adjustment), and short-wavelength light is the most potent for eliciting those responses; however, limited work indicates it may not be required for alerting. We developed similar-appearing light boxes (correlated color temperature: 3000–3375 K; photopic illuminance: 260–296 lux), enriched (SW+, melanopic EDI: 294 lux) or attenuated (SW-, melanopic EDI: 103 lux) in short-wavelength energy, and implemented them on a high-security watchfloor. Efficacy and feasibility of these two novel lighting interventions were assessed in personnel working 12-hour night shifts (n  = 47) in this within-participants, crossover study. For each intervention condition, light boxes were arranged across the front of the watchfloor and illuminated the entire shift; blue-blocking glasses were worn post-shift and before sleep; and sleep masks were used while sleeping. Comparisons between baseline and intervention conditions included alertness, sleep, mood, quality of life (QOL), and implementation measures. On-shift alertness (Karolinska Sleepiness Scale) increased in SW− compared to baseline, while changes in SW+ were more limited. Under SW+, both mood and sleep improved. Psychomotor vigilance task performance did not vary by condition; however, perceived performance and QOL were higher, and reported caffeine consumption and sleep onset latency were lower, under SW−. For both interventions, satisfaction and comfort were high, and fewer symptoms and negative feelings were reported. The addition of spectrally engineered lights to this unique work environment improved sleep, alertness, and mood without compromising visual comfort and satisfaction. This paper is part of the Sleep and Circadian Rhythms: Management of Fatigue in Occupational Settings Collection. [ABSTRACT FROM AUTHOR]

Vector controlled-source audio-frequency magnetotellurics (CSAMT) emits electromagnetic waves with a low directivity coefficient using a grounded horizontal electric dipole (HED). During observations in the far-field region (FfR), only a fraction of radiation energy is used. To improve the signal-to-noise ratio (SNR) in the FfR, it is necessary to increase the power of the transmitter or shorten the transceiver distance, but it will restrict the development of vector CSAMT. Comparatively, the tensor CSAMT uses HEDs in two directions to measure geological bodies in every direction. If the geological conditions of two HEDs are vastly different, it is easy to cause issues, such as an imbalance of the SNR in two directions of the receiving point. This paper presents a comparative study of a novel arithmetic amplitude-phase (AAP) weighted beamforming method (BFM) in vector and tensor CSAMT, which uses multiple HEDs to transmit signals with controlled amplitude ratio and phase difference to modulate the wavefront, thereby achieving beam steering and other additional functions (such as amplitude compensation). By concentrating the radiation energy in the area of interest (AoI) using BFM, the SNR can be largely regulated. The comparative simulation and analysis demonstrate that the BFM has advantages in improving energy utilization and beam steering in vector and tensor CSAMT. On the premise of same power and transceiver distance, using the AAP-weighted BFM, the SNR received in the AoI can meet the requirements better than that received via the traditional method.

Introduction: The number and variety of alternative tobacco and nicotine products that can potentially provide reduced-risk choices for cigarette smokers who switch completely to such products instead of continued smoking have grown substantially in the past decade. Innovation and choice are likely to improve the prospects of smokers making the switch, but this provides challenges to regulators and manufacturers to ensure that changes to regulations and products promote and do not hinder contributions to tobacco harm reduction.Aims and Methods: This paper looks at where bridging data sets for tobacco heating products, closed system vaping products, and oral nicotine products might enable innovation while protecting the interests of consumers.Results: We review product data from chemical studies and a toxicological study showing how bridging can be applied and consider what product development changes might allow bridging from existing datasets or trigger the need for new ones.Conclusions: Bridging across specific product ranges can increase the speed of innovation, foster competition, and limit the burden of assessment for regulators while maintaining product safety and quality.Implications: Bridging partial data sets is an established practice within other industries, that aims to improve efficiency with regulatory approvals, accepts natural product variation, and supports product innovation. We review product data from chemical studies and a toxicological study showing how bridging can be applied and consider what product development changes might allow bridging from existing datasets or trigger the need for new ones. This in turn can increase the speed of innovation, foster competition, and limit the burden of assessment for regulators while maintaining product safety and quality. [ABSTRACT FROM AUTHOR]

Introduction: In India, 38.7% of adults are exposed to SHS at home and 30.2% at work. This paper estimates the direct economic costs of diseases attributable to secondhand smoking (SHS) in India for persons aged 15 years and above.Aims and Methods: Nationally representative data on healthcare expenditures, healthcare utilization, and SHS prevalence were used to estimate economic costs attributable to SHS. A prevalence-based attributable risk approach was used for estimating the attributable direct costs. To estimate the SHS-attributable fraction, the excess utilization of healthcare among SHS exposed non-smokers compared to unexposed non-smokers was estimated using a method of propensity score matching (PSM).Results: The annual direct economic costs attributable to SHS from all diseases in India in the year 2017 for persons aged more than 15 years amounted to INR 566.7 billion (USD 8.7 billion). This amounted to INR 705 per adult non-smoker. The SHS attributable costs were higher among the youngest age group 20 to 24, and women bear 71% of the direct medical costs attributable to SHS.Conclusions: The annual direct economic costs of SHS amount to approximately 0.33% of India's Gross Domestic Product (GDP), or 8.1% of total healthcare expenditures in India. It is also much larger than the total excise tax revenue from cigarettes and bidis. As bidi smoking is the most popular form of smoking in India and bidis are mostly consumed by the poor, a disproportionate burden of SHS is likely borne by poor households in India.Implications: In India, 38.7% of adults are exposed to SHS at home and 30.2% at work. However, there is no estimate of the economic burden of any kind from SHS exposure in India. This study used a prevalence-based attributable risk approach combined with a PSM technique to estimate excess healthcare utilization for SHS exposed non-smokers and the annual direct economic costs of SHS in India. Annual direct SHS-attributable costs in India is INR 566.7 billion (USD 8.7 billion) SHS costs constituted 0.33% of GDP and 8.1% of healthcare expenditures in India. [ABSTRACT FROM AUTHOR]

Health management information systems (HMISs) are essential in programme planning, budgeting, monitoring and evidence-informed decision-making. This paper focuses on donor transitions in two upper-middle-income countries, China and Georgia, and explores how national HMIS adaptations were made and what facilitated or limited successful and sustainable transitions. This comparative analytical case study uses a policy triangle framework and a mixed-methods approach to explore how and why adaptations in the HMIS occurred under the Gavi Alliance and the Global Fund–supported programmes in China and Georgia. A review of published and grey literature, key informant interviews and administrative data analysis informed the study findings. Contextual factors such as the global and country context, and health system and programme needs drove HMIS developments. Other factors included accountability on a national and international level; improvements in HMIS governance by establishing national regulations for clear mandates of data collection and reporting rules and creating institutional spaces for data use; investing in hardware, software and human resources to ensure regular and reliable data generation; and capacitating national players to use data in evidence-based decision-making for programme and transition planning, budgeting and outcome monitoring. Not all the HMIS initiatives supported by donors were sustained and transitioned. For the successful adaptation and sustainable transition, five interlinked and closely coordinated support areas need to be considered: (1) coupling programme design with a good understanding of the country context while considering domestic and external demands for information, (2) regulating appropriate governance and management arrangements enhancing country ownership, (3) avoiding silo HMIS solutions and taking integrative approach, (4) ensuring the transition of funding onto domestic budget and enforcing fulfilment of the government's financial commitments and finally (5) investing in technologies and skilled human resources for the HMIS throughout all levels of the health system. Neglecting any of these elements risks not delivering sustainable outcomes. [ABSTRACT FROM AUTHOR]

Objectives This paper examines the family ties of older adults in the United States and how they are associated with mental health and social activity. We compare older adults with 4 types of family ties: adults "close" to family in proximity and social network, "kinless" older adults without a partner or children, "distanced" adults who live far from close kin, and "disconnected" older adults who do not report kin in their social network or do not report a location for some kin. Methods Using pooled data from the National Health and Aging Trends Study 2015–2019 for older adults aged 70 and older (N = 24,818 person-waves), we examine how family ties are associated with mental health and social activity, and whether lacking family is tied to poor well-being because older adults' needs are not being met. Results Kinless older adults and disconnected older adults have poorer outcomes (lower mental health scores and less social activity), compared to those close to their family. These findings suggest that both the presence and quality of the connection, as measured here via both location and social network, are critical for understanding which older adults are "at risk." Older adults who were not geographically proximate to their close kin (i.e. distanced) were not disadvantaged relative to those close to their families. Unmet needs do not help explain these patterns. Discussion Our results highlight that family ties are important for older adults well-being, not just through their existence but also their quality and strength. [ABSTRACT FROM AUTHOR]

Objectives Research among older adults reveals that the loss of core network members is a risk factor for loneliness. Still, it is not clear whether all such losses induce similar levels of loneliness, particularly as network members are distributed at varied geographic distances. Neither is it clear whether tie addition—the other ubiquitous aspect of network turnover in later life—offsets the loneliness that arises from different network loss scenarios. Methods This paper scrutinized core network losses across multiple relationship–distance scenarios. We used the fourth and sixth waves of data from the Survey of Health, Ageing, and Retirement in Europe and estimated fixed-effect models. Results The loss of a child from a core network increases feelings of loneliness across variant distances, especially when not complemented by additional connections. Losing relatives or nonkin core connections in proximity (within 1 km and 5 km radius, respectively) is also associated with increased loneliness, yet such effects are also largely mitigated by the addition of new core network members. Discussion The relationship between core network member losses and loneliness can significantly differ based on the nature of the lost connection and its geographic distance. Active rebalancing of one's core network following losses and proactive network expansion can serve as pivotal strategies to prevent loneliness for the aging population. [ABSTRACT FROM AUTHOR]

There has been substantial progress in the development of regenerative medicine strategies for CNS disorders over the last decade, with progression to early clinical studies for some conditions. However, there are multiple challenges along the translational pipeline, many of which are common across diseases and pertinent to multiple donor cell types. These include defining the point at which the preclinical data are sufficiently compelling to permit progression to the first clinical studies; scaling-up, characterization, quality control and validation of the cell product; design, validation and approval of the surgical device; and operative procedures for safe and effective delivery of cell product to the brain. Furthermore, clinical trials that incorporate principles of efficient design and disease-specific outcomes are urgently needed (particularly for those undertaken in rare diseases, where relatively small cohorts are an additional limiting factor), and all processes must be adaptable in a dynamic regulatory environment. Here we set out the challenges associated with the clinical translation of cell therapy, using Huntington's disease as a specific example, and suggest potential strategies to address these challenges. Huntington's disease presents a clear unmet need, but, importantly, it is an autosomal dominant condition with a readily available gene test, full genetic penetrance and a wide range of associated animal models, which together mean that it is a powerful condition in which to develop principles and test experimental therapeutics. We propose that solving these challenges in Huntington's disease would provide a road map for many other neurological conditions. This white paper represents a consensus opinion emerging from a series of meetings of the international translational platforms Stem Cells for Huntington's Disease and the European Huntington's Disease Network Advanced Therapies Working Group, established to identify the challenges of cell therapy, share experience, develop guidance and highlight future directions, with the aim to expedite progress towards therapies for clinical benefit in Huntington's disease.

This paper presents comparative evaluation of an application of deep convolutional neural networks (dCNNs) to age invariant face recognition. To this end, we use four distinct dCNN models, the AlexNet, VGGNet, GoogLeNet and ResNet. We assess their performance to recognize face images across aging variations, firstly by fine-tuning the models and secondly using them as face feature extractor. We also suggest a novel synthesized aging augmentation technique suitable for age-invariant face recognition using dCNNs. The face recognition experiments are conducted on three challenging FG-NET, MORPH and LAG aging datasets, and results are benchmarked with a simple CNN. The comparative study allows us to answer (i) when and why transfer learning or feature extraction strategies are useful in age-invariant face recognition scenarios, (ii) the potential of aging synthesized augmentation to increase accuracy and (iii) the choice of appropriate feature normalization and distance metrics to be used with deeply learned features. The extensive experiments, and valuable insights presented in this study can be extended to the design of effective age-invariant face recognition algorithms. [ABSTRACT FROM AUTHOR]

Background To address social inequalities in adolescent substance use and consequent disparities in health, it is important to identify the mechanisms of the association between substance use and academic performance. We study the role of health literacy (HL) in the association between academic performance and weekly smoking, monthly alcohol use and cannabis ever-use among adolescents in Europe. Methods SILNE-R school survey data, which was collected in 2016–17 with paper-and-pencil-method from Hanover (GE), Amersfoort (NL) and Tampere (FI), were used (N  = 5088, age 13–19). Health Literacy for School-aged Children instrument was used to assess students' HL. Logistic regression analyzed the association of substance use with academic performance and HL, separately and in the same model. Linear and multinomial logistic regression analyzed the association between academic performance and HL. Results Poor academic performance compared with high was associated with smoking [odds ratio (OR) 3.94, 95% confidence interval (CI) 2.83–5.49], alcohol use (OR: 2.94, 95% CI: 2.34–3.68) and cannabis use (OR: 2.56, 95% CI: 1.89–3.48). Poor HL was also associated with each substance use (with ORs of 2.32, 1.85 and 1.29). HL was positively associated with academic performance (β = 1.04, 95% CI: 0.89–1.20). The associations between academic performance and substance use were only slightly attenuated after controlling for HL. Conclusions Academic performance and HL were both determinants of substance use, confirming their role in tackling the disparities in substance use. However, HL did not demonstrably mediate the association between academic performance and substance use. A wider set of factors needs to be tackled to address emerging social inequalities in adolescent substance use. [ABSTRACT FROM AUTHOR]

Background: Convalescent plasma has been used to treat many viral diseases including Ebola. The manufacture of a purified anti-Ebola virus (EBOV) intravenous immunoglobulin (IVIG) from pooled convalescent plasma is described in this paper.Methods: An enzyme-linked immunosorbent assay (ELISA) targeting an EBOV surface glycoprotein antigen was used to determine the immunoglobulin titer of pooled plasma and purified anti-EBOV IVIG. Anti-EBOV IVIG was also tested in neutralization assays using a vesicular stomatitis virus pseudovirion expressing EBOV glycoprotein on its surface and with live EBOV. Finally, the efficacy of the anti-EBOV IVIG was assessed in a mouse model of EBOV infection.Results: In the ELISA, the anti-EBOV IVIG was shown to have a 7-fold increase in immunoglobulin G (IgG) titer over pooled convalescent plasma. In both the pseudovirion and live virus assays, the anti-EBOV IVIG showed approximately 5- to 6-fold increased potency over pooled plasma. Anti-EBOV IVIG also significantly improved survivability in mice infected with the virus when administered concurrently or 2 days after infection.Conclusions: These data support this purified anti-EBOV IVIG merits additional investigation and clinical trials for treatment and postexposure prophylaxis of Ebola virus disease. The experience gained can be applied to manufacture hyperimmune globulins against other emerging viruses. [ABSTRACT FROM AUTHOR]

Introduction: Diversification away from tobacco production has been identified as a priority for Malawi, historically one of the world's most tobacco-reliant countries.Methods: This paper refers to a nationally representative data set to characterize broad trends in production since 2000 to understand whether Malawi is shifting away from tobacco and how production has changed over time.Results: From 2004 to 2019, the share of Malawian crop farmers producing tobacco fell from 16% to 5%, and tobacco's share of the total value of crop production also declined sharply. Tobacco farms are generally growing larger (in size and scale of production) over time. However, land productivity remains low, with net returns of 93 000 MWK (128 USD) per hectare at the median. Farm-gate prices for tobacco have declined relative to the prices of maize or fertilizer, rendering tobacco a less lucrative avenue to generate the cash income needed to purchase these key items. In addition, the share of the export price received by farmers has also declined over time, with the median farm-gate price representing 32% of the export price in 2004 and 18% in 2019.Conclusions: In some respects, a transition away from tobacco has already occurred. Additional research is needed to understand why the farm-gate share of tobacco export prices has declined over this period and how the livelihoods of smallholder farm-households that exited tobacco production have been affected.Implications: To the extent that tobacco prices appear to be declining, there is a need to rigorously assess whether farmers have suitable crop alternatives (with established markets) and other livelihood options. Likely, investments are yet needed to foster strong alternatives to tobacco; such investments include research and development in on-farm technologies to raise the productivity of non-tobacco crops, as well as improvements in non-tobacco value chains to reduce transportation costs and promote private investment.

We read with interest the paper by Koda I et al i .[1] entitled 'Randomized trial of granulocyte colony-stimulating factor for spinal cord injury'. However, the manner in which the results are presented - and I post hoc i subgroup analyses performed - would suggest that the mixed-effect model described in the protocol was not used. Study participants, who were in the acute phase of their spinal cord injury, enrolled in the trial in the hope that, in the future, others who sustain a spinal cord injury would have improved outcomes.

Background: Spermatozoa acquire their motility and fertilizing abilities during their maturation through the epididymis. This process is controlled by epididymal epithelial cells that possess features adapted to sense and respond to their surrounding environment and to communicate with spermatozoa. During the past decade, new intercellular communication processes have been discovered, including the secretion and transport of molecules from the epithelium to spermatozoa via extracellular vesicles (EVs), as well as sensing of the intraluminal milieu by cellular extensions.Objective and Rationale: This review addresses recent findings regarding epididymal epithelial cell features and interactions between spermatozoa and the epididymal epithelium as well as epigenetic modifications undergone by spermatozoa during transit through the epididymal microenvironment.Search Methods: A systematic search was conducted in Pubmed with the keyword 'epididymis'. Results were filtered on original research articles published from 2009 to 2021 and written in the English language. One hundred fifteen original articles presenting recent advancements on the epididymis contribution to sperm maturation were selected. Some additional papers cited in the primary reference were also included. A special focus was given to higher mammalian species, particularly rodents, bovines and humans, that are the most studied in this field.Outcomes: This review provides novel insights into the contribution of epididymal epithelium and EVs to post-testicular sperm maturation. First, new immune cell populations have been described in the epididymis, where they are proposed to play a role in protecting the environment surrounding sperm against infections or autoimmune responses. Second, novel epididymal cell extensions, including dendrites, axopodia and primary cilia, have been identified as sensors of the environment surrounding sperm. Third, new functions have been outlined for epididymal EVs, which modify the sperm epigenetic profile and participate in transgenerational epigenetic inheritance of paternal traits.Wider Implications: Although the majority of these findings result from studies in rodents, this fundamental research will ultimately improve our knowledge of human reproductive physiopathologies. Recent discoveries linking sperm epigenetic modifications with paternal environmental exposure and progeny outcome further stress the importance of advancing fundamental research on the epididymis. From this, new therapeutic options for infertile couples and better counseling strategies may arise to increase positive health outcomes in children conceived either naturally or with ART.

Background: Human male infertility has a notable genetic component, including well-established diagnoses such as Klinefelter syndrome, Y-chromosome microdeletions and monogenic causes. Approximately 4% of all infertile men are now diagnosed with a genetic cause, but a majority (60-70%) remain without a clear diagnosis and are classified as unexplained. This is likely in large part due to a delay in the field adopting next-generation sequencing (NGS) technologies, and the absence of clear statements from field leaders as to what constitutes a validated cause of human male infertility (the current paper aims to address this). Fortunately, there has been a significant increase in the number of male infertility NGS studies. These have revealed a considerable number of novel gene-disease relationships (GDRs), which each require stringent assessment to validate the strength of genotype-phenotype associations. To definitively assess which of these GDRs are clinically relevant, the International Male Infertility Genomics Consortium (IMIGC) has identified the need for a systematic review and a comprehensive overview of known male infertility genes and an assessment of the evidence for reported GDRs.Objective and Rationale: In 2019, the first standardised clinical validity assessment of monogenic causes of male infertility was published. Here, we provide a comprehensive update of the subsequent 1.5 years, employing the joint expertise of the IMIGC to systematically evaluate all available evidence (as of 1 July 2020) for monogenic causes of isolated or syndromic male infertility, endocrine disorders or reproductive system abnormalities affecting the male sex organs. In addition, we systematically assessed the evidence for all previously reported possible monogenic causes of male infertility, using a framework designed for a more appropriate clinical interpretation of disease genes.Search Methods: We performed a literature search according to the PRISMA guidelines up until 1 July 2020 for publications in English, using search terms related to 'male infertility' in combination with the word 'genetics' in PubMed. Next, the quality and the extent of all evidence supporting selected genes were assessed using an established and standardised scoring method. We assessed the experimental quality, patient phenotype assessment and functional evidence based on gene expression, mutant in-vitro cell and in-vivo animal model phenotypes. A final score was used to determine the clinical validity of each GDR, across the following five categories: no evidence, limited, moderate, strong or definitive. Variants were also reclassified according to the American College of Medical Genetics and Genomics-Association for Molecular Pathology (ACMG-AMP) guidelines and were recorded in spreadsheets for each GDR, which are available at imigc.org.Outcomes: The primary outcome of this review was an overview of all known GDRs for monogenic causes of human male infertility and their clinical validity. We identified a total of 120 genes that were moderately, strongly or definitively linked to 104 infertility phenotypes.Wider Implications: Our systematic review curates all currently available evidence to reveal the strength of GDRs in male infertility. The existing guidelines for genetic testing in male infertility cases are based on studies published 25 years ago, and an update is far overdue. The identification of 104 high-probability 'human male infertility genes' is a 33% increase from the number identified in 2019. The insights generated in the current review will provide the impetus for an update of existing guidelines, will inform novel evidence-based genetic testing strategies used in clinics, and will identify gaps in our knowledge of male infertility genetics. We discuss the relevant international guidelines regarding research related to gene discovery and provide specific recommendations to the field of male infertility. Based on our findings, the IMIGC consortium recommend several updates to the genetic testing standards currently employed in the field of human male infertility, most important being the adoption of exome sequencing, or at least sequencing of the genes validated in this study, and expanding the patient groups for which genetic testing is recommended.

Leisure-time physical activity (LTPA) is a crucial behavior to reduce the global burden of disease. The objective of this study was to understand the relationship between LTPA, employment status, and physical workload (PWL). This study analyzed data from 38 449 individuals interviewed in the National Health Survey (NHS), representative of the Brazilian population. This paper examines LTPA in the last 30 days and whether participants achieved the recommended physical activity (≥150 min week−1) according to employment status and PWL utilizing Poisson regression models. One third and ¼ of the participants reported LTPA in the last 30 days and achieved the recommended LTPA, respectively. Intense PWL was reported by 28.7% [95% confidence interval (CI): 27.8–29.6%] of participants; 32.2% among men (95% CI: 31.0–33.5%); 24.3% among women (95% CI: 23.1–25.5%). Precarious employment was associated with a lower prevalence of physical activity among men [adjusted prevalence ratio (PRa) = 0.92; P = 0.016], but not among women (PRa = 1.11; P = 0.039). Employment policies and protection of the work environment are relevant aspects to stimulate physical activity, and may vary by gender. [ABSTRACT FROM AUTHOR]

Background While tobacco smoking has declined among UK youth in recent decades, cannabis use has begun to show some growth. Given their interrelationship, growth in cannabis use may act as a barrier to continued reduction in youth smoking. This paper assesses recent tobacco and cannabis use trends in Wales, and their association, to explore whether change in cannabis use might have impacted youth tobacco smoking prevalence. Methods Repeat cross-sectional data on tobacco and cannabis use were obtained from biennial Welsh Student Health and Wellbeing surveys between 2013 and 2019. Data were pooled and analysed using logistic regression with adjustment for school-level clustering. Results No change in regular youth tobacco smoking was observed between 2013 and 2019. In contrast, current cannabis use increased during this time, and cannabis users had significantly greater odds of regular tobacco smoking. After adjusting for change in cannabis use, a significant decline in youth tobacco smoking was observed (OR 0.95; 95% confidence intervals: 0.92, 0.97). Conclusion Recent growth in cannabis use among young people in Wales may have offset prospective declines in regular tobacco smoking. Further reductions in youth smoking may require more integrated policy approaches to address the co-use of tobacco and cannabis among adolescents. [ABSTRACT FROM AUTHOR]

Site planning not only involves the arrangement of a large number of elements but also considers the complexity of urban systems; hence, the design process involves large workloads and is time consuming. Retrieving similar existing cases helps architects optimize or accelerate the design process. This paper proposes a computational approach that provides valuable references by retrieving similar cases. Three types of attributes are extracted to represent a given parcel: land-use attributes, geometric attributes (area, orientation, etc.), and environmental attributes (greening rate, surrounding facilities, etc.). The complete hierarchical retrieval process is divided into three phases. The first phase selects cases whose land-use attributes are consistent with the target parcel. Then, the similarity distances between the given target parcel and the selected cases are calculated using geometric attributes. The eXtreme Gradient Boosting (XGBoost) classifier is adopted to determine which case is similar to the target parcel. Finally, similarity scores of the retrieved cases are calculated based on the environmental attributes to provide more options during the actual design. In total, 1189 cases with different land-use types in Beijing were collected for the case base. The comparative experimental results confirmed that the proposed ensemble learning-based hierarchical retrieval of similar cases approach improves the accuracy of retrieval results. Furthermore, we use a real-world target parcel to demonstrate the superiority and flexibility of the retrieval process. [ABSTRACT FROM AUTHOR]

Aims Primary aim: to determine the efficacy of FAST (the Fast Alcohol Screening Test) for detecting harmful and dependent levels of alcohol use. Secondary aim: to compare the performance of the FAST to two short forms of the Alcohol Use Disorder Identification Test (AUDIT): the AUDIT-C and AUDIT-3. Methods Data from 3336 individuals in South Wales, compiled from full AUDIT datasets, were examined. AUROC analysis, alongside measures of sensitivity and specificity of the FAST, AUDIT-C and AUDIT-3 were utilized for the identification of harmful and dependent alcohol use. Results The FAST demonstrated efficacy in the identification of harmful and dependent levels of alcohol use, with superior performance to both the AUDIT-C and AUDIT-3. Conclusion The present paper demonstrates the potential of the FAST as a cost- and time-effective method for appropriate screening and signposting in the stepped care model utilized by many health care and treatment services. Further studies are needed to ensure validity, both within the general population and for specific services and populations. [ABSTRACT FROM AUTHOR]

Background: Stanniocalcin-1 (STC-1) is a widely expressed glycoprotein hormone involved in a diverse spectrum of physiological and pathophysiological processes including angiogenesis, mineral homeostasis, cell proliferation, inflammation and apoptosis. Over the last 20 years, numerous studies have reported STC-1 expression within female reproductive tissues including the uterus, ovaries and placenta and implicated STC-1 in processes such as ovarian follicular development, blastocyst implantation, vascular remodelling in early pregnancy and placental development. Notably, dysregulation of STC-1 within reproductive tissues has been linked to the onset of severe reproductive disorders including endometriosis, polycystic ovary syndrome, poor trophoblast invasion and placental perfusion in early pregnancy. Furthermore, significant changes in tissue expression and in maternal systemic concentration take place throughout pregnancy and further substantiate the vital role of this protein in reproductive health and disease.Objective and Rationale: Our aim is to provide a comprehensive overview of the existing literature, to summarise the expression profile and roles of STC-1 within the female reproductive system and its associated pathologies. We highlight the gaps in the current knowledge and suggest potential avenues for future research.Search Methods: Relevant studies were identified through searching the PubMed database using the following search terms: 'stanniocalcin-1', 'placenta', 'ovary', 'endometrium', 'pregnancy', 'reproduction', 'early gestation'. Only English language papers published between 1995 and 2020 were included.Outcomes: This review provides compelling evidence of the vital function that STC-1 plays within the female reproductive system. The literature presented summarise the wide expression profile of STC-1 within female reproductive organs, as well as highlighting the putative roles of STC-1 in various functions in the reproductive system. Moreover, the observed link between altered STC-1 expression and the onset of various reproductive pathologies is presented, including those in pregnancy whose aetiology occurs in the first trimester. This summary emphasises the requirement for further studies on the mechanisms underlying the regulation of STC-1 expression and function.Wider Implications: STC-1 is a pleiotropic hormone involved in the regulation of a number of important biological functions needed to maintain female reproductive health. There is also growing evidence that dysregulation of STC-1 is implicated in common reproductive and obstetric disorders. Greater understanding of the physiology and biochemistry of STC-1 within the field may therefore identify possible targets for therapeutic intervention and/or diagnosis. [ABSTRACT FROM AUTHOR]

Background: Worldwide, the prevalence of obesity in women of reproductive age is increasing. Bariatric surgery is currently viewed as the most effective, long-term solution for this problem. Preconception bariatric surgery can reduce the prevalence of obesity-related subfertility and adverse maternal, pregnancy and birth outcomes. Maternal health during the periconception period is crucial for optimal gametogenesis and for embryonic and fetal development which also affects health in the later lives of both mother and offspring. Although preconception bariatric surgery improves several pregnancy outcomes, it can also increase the prevalence of pregnancy complications due to excessive and rapid weight loss. This can lead to iatrogenic malnutrition with vitamin deficiencies and derangements in metabolic and endocrine homeostasis. Thus, bariatric surgery can greatly influence periconception maternal health with consequences for reproduction, pregnancy and health in later life. However, its influence on periconception maternal health itself has never been reviewed systematically.Objective and Rationale: The aim of this review was to investigate associations between bariatric surgery and determinants of periconception maternal health such as endocrine changes, fertility, vitamin status, irregular menstrual cycles, miscarriages and congenital malformations.Search Methods: Medline, Embase, PubMed, Web of Science, Google Scholar and the Cochrane databases were used for the literature search until 1 November 2020. The search strategy terms included, among others, bariatric surgery, hormones, fertility, malformations, miscarriages and vitamin status. We searched for human studies that were written in English. Abstracts, reviews, meta-analyses and conference papers were excluded. The ErasmusAGE score was used to assess the quality of the included studies.Outcomes: A total of 51 articles were analysed. The mean quality score was 5 (range 2-8). After bariatric surgery, hormonal axes normalized and menstrual cycle regularity was restored, resulting in increased fertility. Overall, there were no short-term risks for reproductive outcomes such as the increased risk of miscarriages or congenital malformations. However, the risk of vitamin deficiencies was generally increased after bariatric surgery. A meta-analysis of 20 studies showed a significant decrease in infertility (risk difference (RD) -0.24, 95% confidence interval (CI) -0.42, -0.05) and menstrual cycle irregularities (RD -0.24, 95% CI -0.34, -0.15) with no difference in rates of miscarriage (RD 0.00, 95% CI -0.09, 0.10) and congenital malformations (RD 0.01, 95% CI -0.02, 0.03).Wider Implications: The current systematic review and meta-analysis show associations between bariatric surgery and periconception maternal health and underlines the need for providing and personalizing preconception care for women after bariatric surgery. We recommend preconception care including the recommendation of postponing pregnancy until weight loss has stabilized, irrespective of the surgery-to-pregnancy interval, and until vitamin status is normalized. Therefore, regular monitoring of vitamin status and vitamin supplementation to restore deficiencies is recommended. Furthermore, this systematic review emphasizes the need for a long-term follow-up research of these women from the periconception period onwards as well as their pregnancies and offspring, to further improve care and outcomes of these mothers and children.
