The Formin FMNL3 Controls Early Apical Specification in Endothelial Cells by Regulating the Polarized Trafficking of Podocalyxin

SummaryAngiogenesis is the fundamental process by which new blood vessels form from pre-existing vasculature. It plays a critical role in the formation of the vasculature during development and is triggered in response to tissue hypoxia in adult organisms. This process requires complex and coordinated regulation of the endothelial cell cytoskeleton to control cell shape and polarity. In our previous work, we showed that the cytoskeletal regulator FMNL3/FRL2 controls the alignment of stabilized microtubules during polarized endothelial cell elongation and that depletion of FMNL3 retards elongation of the intersegmental vessels in zebrafish [1]. Recent work has shown that FMNL3 is also needed for vascular lumen formation [2], a critical element of the formation of functional vessels. Here, we show that FMNL3 interacts with Cdc42 and RhoJ, two Rho family GTPases known to be required for lumen formation. FMNL3 and RhoJ are concentrated at the early apical surface, or AMIS, and regulate the formation of radiating actin cables from this site. In diverse biological systems, formins mediate polarized trafficking through the generation of similar actin filaments tracks. We show that FMNL3 and RhoJ are required for polarized trafficking of podocalyxin to the early apical surface—an important event in vascular lumenogenesis

Marginalisation, discrimination and the health of Latino immigrant day labourers in a central North Carolina community

The morbidity and mortality of Latino immigrants in the United States (US) stem from a complex mix of policy, culture, discrimination, and economics. Immigrants working as day labourers may be particularly vulnerable to the negative influences of these social factors due to limited access to social, financial, and legal resources. We aimed to understand how the health of male Latino day labourers in North Carolina, US is influenced by their experiences interacting with their community and perceptions of their social environment. To respond to our research questions, we conducted three focus groups (n=9, n =10, n=10) and a photovoice project (n=5) with Latino male immigrants between October 2013 and March 2014. We conducted a thematic analysis of transcripts from the discussions in the focus groups and the group of Photovoice participants. We found that men's health and well-being were primarily shaped by their experiences and feelings of discrimination and marginalization. We identified three main links between discrimination/marginalization and poor health: (1) dangerous work resulted in workplace injuries or illnesses, (2) unsteady employment caused stress, anxiety and insufficient funds for health care, and (3) exclusionary policies and treatment resulted in limited healthcare accessibility. Health promotion with Latino immigrant men in new settlement areas could benefit from community-building activities, addressing discrimination, augmenting the reach of formal health care, and building upon the informal mechanisms that immigrants rely on to meet their health needs. Reforms to immigration and labour policies are also essential to addressing these structural barriers to health for these men

Coregistering functional near-infrared spectroscopy with underlying cortical areas in infants

Functional near-infrared spectroscopy (fNIRS) is becoming a popular tool in developmental neuroscience for mapping functional localized brain responses. However, as it cannot provide information about underlying anatomy, researchers have begun to conduct spatial registration of fNIRS channels to cortical anatomy in adults. The current work investigated this issue with infants by coregistering fNIRS and magnetic resonance imaging (MRI) data from 55 individuals. Our findings suggest that fNIRS channels can be reliably registered with regions in the frontal and temporal cortex of infants from 4 to 7 months of age. Although some macro-anatomical regions are difficult to consistently define, others are more stable and fNIRS channels on an age-appropriate MRI template are often consistent with individual infant MRIs. We have generated a standardized scalp surface map of fNIRS channel locators to reliably locate cortical regions for fNIRS developmental researchers. This new map can be used to identify the inferior frontal gyrus, superior temporal sulcus (STS) region [which includes the superior and middle temporal gyri (MTG) nearest to the STS], and MTG and temporal-parietal regions in 4- to 7-month-old infants. Future work will model data for the whole head, taking into account the properties of light transport in tissue, and expanding to different ages across development

Nutritional deficiencies in homeless persons with problematic drinking:A systematic review

BACKGROUND: A significant proportion of homeless people drink alcohol excessively and this can lead to malnutrition and consequent medical problems. The aim of this review was to assess the evidence on the range of nutritional deficiencies in the homeless problem-drinking populations. METHODS: We conducted a comprehensive search of nine scientific literature databases and 13 grey literature sources. We included studies of any design that included homeless population with problem-drinking and reported measures of nutritional deficiencies in urine or blood. Study selection and data extraction was done by one reviewer and checked by another. Data on malnutrition profile were summarized narratively. RESULTS: We found nine studies reporting nutritional deficiencies in homeless populations with problem-drinking. The oldest study was from the 1950s and the most recent from 2013. The following nutrients were reported across studies: vitamins B1, B2, B6, B9, B12, C, A, and E; haemoglobin; and albumin. The most common deficiencies reported were of vitamin B1 (prevalence of deficiency was 0, 2, 6, 45, and 51% in five studies) and vitamin C (29, 84, and 95% in three studies). None of the studies were assessed to be at a low risk of bias. CONCLUSIONS: The limited, low quality and relatively old evidence suggests that homeless people who drink heavily may be deficient in vitamin C, thiamine, and other nutrients. New, well conducted studies are needed in order to optimally inform public health interventions aimed at improving deficiencies in this population

Interventions for preventing or treating malnutrition in problem drinkers who are homeless or vulnerably housed:protocol for a systematic review

BACKGROUND: Problem alcohol drinking in homeless and vulnerably housed people can lead to malnutrition, which is associated with complications such as alcohol-related brain damage. Homeless alcohol drinkers are likely to have worse health outcomes and different nutritional needs compared with housed alcohol-drinking persons. It is not clear whether interventions to improve nutritional status in this population have been effective. The purpose of this review is to assess the effectiveness and cost-effectiveness of interventions for preventing or correcting micronutrient deficiencies and other forms of malnutrition and related comorbidities in this population. METHODS/DESIGN: A systematic search for studies of a nutrition-based intervention applied in the homeless or vulnerably housed population with problem drinking will be conducted. The following electronic databases will be systematically searched for relevant studies: MEDLINE, EMBASE, Web of Science, PsycINFO, CAB abstracts, CINAHL, Cochrane Public Health Group Register and Cochrane Drugs and Alcohol Group Register. Screening of identified abstracts for relevance and assessment of papers for inclusion will be done in duplicate. One reviewer will extract data from the studies and assess quality, and this will be checked by another reviewer. Discrepancies will be resolved by consensus. The primary outcomes are (mal)nutrition status or micronutrient deficiencies or change in (mal)nutrition status or micronutrient deficiencies, measures of liver damage and cognitive function. Secondary outcomes include comorbidities, quality of life and functional scales, resources used to deliver treatment, uptake/acceptability of the intervention and engagement with treatment services. Results will be analysed descriptively, and, if appropriate, meta-analyses will be performed. DISCUSSION: The results of this review should help to inform the development of effective interventions that can be implemented in the community to improve the health of homeless people who are problem drinkers.

Feasibility study for a community based intervention for adults with severe chronic fatigue syndrome/ME

Background: Chronic Fatigue Syndrome/ME (CFS/ME) is characterised by debilitating fatigue with many bedbound patients. The study aims were: to determine whether a new intervention could be successfully delivered; to collect quantitative outcome data to guide the design of future studies; to explore qualitatively the experience of patients, carers and clinicians. Methods: Mixed-methods feasibility study with qualitative and quantitative evaluation. Participants: 12 UK patients who were housebound with severe CFS/ME. Intervention: Based on recovery skills identified through a 2.5 year Patient and Public Involvement development process involving individuals with first-hand experience of recovery from CFS/ME, as well as current patients and clinicians. The resulting one year intervention, delivered by a multi-disciplinary team, included domiciliary therapy visits and optional peer support group. Quantitative outcome measures: Patient-reported and therapist-reported outcome measures (including fatigue, physical function, anxiety, depression and other variables) and electronic activity measurement. Results: The study recruited and engaged twelve participants with no serious adverse events or dropouts. At end of intervention, 5/12 participants had improved in fatigue, physical function. Group mean scores improved overall for fatigue (Chalder fatigue scale), physical function (activity and physical function scale) and anxiety. Qualitative interviews suggested that the intervention was acceptable to patients, whilst also highlighting suggestions for improvement. Participants will be followed up for a further year to find out if improvements are sustained. Conclusion: This is the largest study ever conducted in severe CFS/ME and shows significant recovery suggesting further studies are indicated. Treatment is uniquely based on a patient inspired intervention

Is volunteering a public health intervention? A systematic review and meta-analysis of the health and survival of volunteers

Background Volunteering has been advocated by the United Nations, and American and European governments as a way to engage people in their local communities and improve social capital, with the potential for public health benefits such as improving wellbeing and decreasing health inequalities. Furthermore, the US Corporation for National and Community Service Strategic Plan for 2011–2015 focused on increasing the impact of national service on community needs, supporting volunteers’ wellbeing, and prioritising recruitment and engagement of underrepresented populations. The aims of this review were to examine the effect of formal volunteering on volunteers’ physical and mental health and survival, and to explore the influence of volunteering type and intensity on health outcomes. Methods Experimental and cohort studies comparing the physical and mental health outcomes and mortality of a volunteering group to a non-volunteering group were identified from twelve electronic databases (Cochrane Library, Medline, Embase, PsychINFO, CINAHL, ERIC, HMIC, SSCI, ASSIA, Social Care Online, Social Policy and Practice) and citation tracking in January 2013. No language, country or date restrictions were applied. Data synthesis was based on vote counting and random effects meta-analysis of mortality risk ratios. Results Forty papers were selected: five randomised controlled trials (RCTs, seven papers); four non-RCTs; and 17 cohort studies (29 papers). Cohort studies showed volunteering had favourable effects on depression, life satisfaction, wellbeing but not on physical health. These findings were not confirmed by experimental studies. Meta-analysis of five cohort studies found volunteers to be at lower risk of mortality (risk ratio: 0.78; 95% CI: 0.66, 0.90). There was insufficient evidence to demonstrate a consistent influence of volunteering type or intensity on outcomes. Conclusion Observational evidence suggested that volunteering may benefit mental health and survival although the causal mechanisms remain unclear. Consequently, there was limited robustly designed research to guide the development of volunteering as a public health promotion intervention. Future studies should explicitly map intervention design to clear health outcomes as well as use pragmatic RCT methodology to test effects

Betylmania? - Small Standing Stones and the Megaliths of South-West Britain

This paper calls attention to a previously neglected element of thebroad repertoire of monumental megalithic structures that characterize thelater third and second millennia BC across the British Isles – extremely smallstanding stones. Despite their frequency and the complex arrangements andassociations they embody, these miniliths are rarely recorded in detail andfrequently marginalized to a generic background. As a result, they are largelyabsent from interpretative accounts. Drawing upon recent debates regardingmateriality and monument form, alongside the results of excavations explicitlytargeting tiny stone settings, the discussion argues that the phenomenon ofraising and fixing small uprights was not only widespread and persistent, butsheds important light upon the beliefs and ideas driving monumentconstruction during the later Neolithic and Bronze Age
