Randomised controlled feasibility study protocol of the Carers-ID online intervention to support the mental health of family carers of people with intellectual disabilities.

BACKGROUND: Family carers play a crucial role in supporting the health and well-being of people with intellectual disabilities. Given their role and responsibilities, many family carers experience significant and ongoing stress and mental health difficulties. Programmes and interventions which provide training and support to family carers have been shown to have a positive impact on levels of stress and quality of life. However, these are often face to face which can create barriers to full participation. Online interventions have been shown to offer flexibility in delivery compared with traditional face-to-face approaches. The primary objective of this study is to determine the feasibility of delivering the Carers-ID online intervention, while the secondary outcome is improved mental health in family carers of people with intellectual disabilities. METHODS: Family carers (n = 120) will be randomised to receive the intervention (n = 60) or assigned to a wait-list control (n = 60) group. The intervention ( www.Carers-ID.com ) consists of 14 modules which cover topics including the following: promoting resilience, providing peer support, reducing anxiety, managing stress, accessing local supports and managing family conflict and information for siblings who are carers. The intervention has been co-produced with voluntary sector organisations and family carers and tested for acceptability. Primary outcomes for this study include acceptability and feasibility of the outcome measures, recruitment, participation and retention rates and effect sizes. Secondary outcomes will be completed at three time points (baseline, following intervention completion and 3 months after completion). These include the following: the Depression, Anxiety and Stress Scale, the Warwick-Edinburgh Mental Well-being Scale, the Resilience Scale and the Social Connectedness Scale Revised. Participants (n = 12) who have taken part in the intervention arm of the research will be invited to participate in semi-structured interviews as part of the process evaluation. DISCUSSION: The Carers-ID intervention provides an online resource for family carers to support their mental health and well-being and promote their resilience. It represents an affordable and accessible means of delivering such support. Testing the feasibility of the intervention and related trial procedures is required to determine whether a full-scale randomised controlled trial to evaluate the intervention's effectiveness is warranted. TRIAL REGISTRATION: ClinicalTrials.gov : NCT05737823.

Thalamocortical organoids enable in vitro modeling of 22q11.2 microdeletion associated with neuropsychiatric disorders.

Thalamic dysfunction has been implicated in multiple psychiatric disorders. We sought to study the mechanisms by which abnormalities emerge in the context of the 22q11.2 microdeletion, which confers significant genetic risk for psychiatric disorders. We investigated early stages of human thalamus development using human pluripotent stem cell-derived organoids and show that the 22q11.2 microdeletion underlies widespread transcriptional dysregulation associated with psychiatric disorders in thalamic neurons and glia, including elevated expression of FOXP2. Using an organoid co-culture model, we demonstrate that the 22q11.2 microdeletion mediates an overgrowth of thalamic axons in a FOXP2-dependent manner. Finally, we identify ROBO2 as a candidate molecular mediator of the effects of FOXP2 overexpression on thalamic axon overgrowth. Together, our study suggests that early steps in thalamic development are dysregulated in a model of genetic risk for schizophrenia and contribute to neural phenotypes in 22q11.2 deletion syndrome.

A novel gelatinized barium sulfate injection method for assessment of bronchoalveolar lavage parameters.

INTRODUCTION: Bronchoalveolar lavage (BAL) is frequently used in pulmonary medicine though it requires further optimization. Practical obstacles such as patient safety and procedural limitation have to date precluded large, controlled trials aimed at standardization of BAL procedure. Indeed, BAL guidelines are based on observational data. Innovative research methods are necessary to advance the clinical practice of BAL. METHODS: In our study, we evaluated the effect of injecting a gelatinized barium solution into different lobes and segments of cadaveric lungs. As the technique requires an irreversible injection into lung airspaces, it is not suitable for in vivo purposes. We measured the volume returned from BAL as well as the distribution of BAL injection via dissection. Segmental anatomic orientation was compared to a radiologist's impression of plain film radiographs taken of injected lungs. RESULTS: Mean injected volume distributions were greatest in the upper lobes and lowest in the lower lobes; mean ratios of injected volume distribution to lung lobe volume also followed this trend. Cannulated bronchi orders favored lower branches in the upper lobe and higher branches in the lower lobes. Segmental anatomy varied by the lung lobe injected and was most varied in the lower lobes. CONCLUSION: This novel gelatinized-barium injection technique provides a minimally complex method to yield clinically meaningful feedback on the performance of BAL. The technique is also adaptable to study of procedural parameters in the context of variable lung anatomies and pathologies.

Allied health professional support for children and young adults living in and leaving care: A systematic scoping review.

BACKGROUND: Children and young people living in and leaving care are known to have experienced significant childhood adversity and trauma resulting in potentially deleterious impact on their health and well-being across the life course. Studies point to the complex needs of this population who may benefit from allied health professional (AHP)-related support with limited studies located. This review sought to address this gap by systematically scoping empirical literature focused on the provision of AHP support to this cohort of children and young adults to assist an understanding of the service needs for this vulnerable population. METHODS: This scoping review followed Arskey and O'Malley's five steps framework (2005) to identify and review relevant literature. A focus on identifying the evidence, challenges and gaps in research relating to AHP support for children and young people living in and leaving care was initially agreed, followed by a systematic search using a combination of three key concepts to identify relevant studies in five AHP disciplinary areas to identify best evidence in the past decade (2011-2021). Study inclusion criteria were based on empirical studies of children and young people living in care (0-17 years) and leaving care (18-25 years). A data extraction table was formulated as a means of charting the data, aligned with the scope and objectives of this review. Finally, data were subsequently collated, synthesised and reported based on key thematic areas emerging from included studies regarding AHP support to children and young people living in and leaving care. RESULTS: A total of 13 studies met the review inclusion criteria. Included studies reported specifically on speech and language therapist (SLT; n = 5), occupational therapist (OT; n = 3) and arts-based therapies (n = 5). No studies were identified with regard to the use of physiotherapy and dietetics with this population. Results indicated that children and young people living in and leaving care have high rates of speech, language, communication and sensory needs. More rigorous screening, assessment and early intervention were identified as essential for this vulnerable group. Increased multidisciplinary collaboration and OT support for young adults in preparation for transition to independent living was identified as an urgent requirement. Included studies indicate promising results in relation to access to arts-based therapies with particular reference to identity formation for children and young people living in and leaving care. CONCLUSIONS: Although evidence of effectiveness remains limited, AHP service provision (specifically speech and language therapy, occupational therapy and arts-based therapies) has the potential to contribute positively to addressing the complex and interacting needs of this vulnerable population. As a result, it is recommended that AHP service provision is integrated into the collaborative, multidisciplinary care available to children living in and leaving care. More extensive, higher quality research related to the benefits of AHP provision for this population of children and young people is essential to provide a more robust evidence base across the various professional disciplines that constitute allied health provision.

A screen of drug-like molecules identifies chemically diverse electron transport chain inhibitors in apicomplexan parasites.

Apicomplexans are widespread parasites of humans and other animals, and include the causative agents of malaria (Plasmodium species) and toxoplasmosis (Toxoplasma gondii). Existing anti-apicomplexan therapies are beset with issues around drug resistance and toxicity, and new treatment options are needed. The mitochondrial electron transport chain (ETC) is one of the few processes that has been validated as a drug target in apicomplexans. To identify new inhibitors of the apicomplexan ETC, we developed a Seahorse XFe96 flux analyzer approach to screen the 400 compounds contained within the Medicines for Malaria Venture 'Pathogen Box' for ETC inhibition. We identified six chemically diverse, on-target inhibitors of the ETC in T. gondii, at least four of which also target the ETC of Plasmodium falciparum. Two of the identified compounds (MMV024937 and MMV688853) represent novel ETC inhibitor chemotypes. MMV688853 belongs to a compound class, the aminopyrazole carboxamides, that were shown previously to target a kinase with a key role in parasite invasion of host cells. Our data therefore reveal that MMV688853 has dual targets in apicomplexans. We further developed our approach to pinpoint the molecular targets of these inhibitors, demonstrating that all target Complex III of the ETC, with MMV688853 targeting the ubiquinone reduction (Qi) site of the complex. Most of the compounds we identified remain effective inhibitors of parasites that are resistant to Complex III inhibitors that are in clinical use or development, indicating that they could be used in treating drug resistant parasites. In sum, we have developed a versatile, scalable approach to screen for compounds that target the ETC in apicomplexan parasites, and used this to identify and characterize novel inhibitors.

Three cases of black pleural effusion.

Black pleural effusions (BPE) are rare, exudative pleural effusions that produce a black fluid on thoracentesis. While the name and definition of this pathology is undeniably simple, the etiologies, outcomes, and treatments for BPE are incredibly complex. Currently, BPE is not well-demonstrated in the literature. This case series reports three patients with different etiologies, past medical histories, presenting symptoms, treatments, and outcomes. BPE caused by pancreatic-pleural fistula and opportunistic infections are demonstrated in this case series. This report shows that early identification and treatment of the underlying cause of BPE is critical to the recovery of the patients.

An essential role for an Fe-S cluster protein in the cytochrome c oxidase complex of Toxoplasma parasites.

The mitochondrial electron transport chain (ETC) of apicomplexan parasites differs considerably from the ETC of the animals that these parasites infect, and is the target of numerous anti-parasitic drugs. The cytochrome c oxidase complex (Complex IV) of the apicomplexan Toxoplasma gondii ETC is more than twice the mass and contains subunits not found in human Complex IV, including a 13 kDa protein termed TgApiCox13. TgApiCox13 is homologous to a human iron-sulfur (Fe-S) cluster-containing protein called the mitochondrial inner NEET protein (HsMiNT) which is not a component of Complex IV in humans. Here, we establish that TgApiCox13 is a critical component of Complex IV in T. gondii, required for complex activity and stability. Furthermore, we demonstrate that TgApiCox13, like its human homolog, binds two Fe-S clusters. We show that the Fe-S clusters of TgApiCox13 are critical for ETC function, having an essential role in mediating Complex IV integrity. Our study provides the first functional characterisation of an Fe-S protein in Complex IV.

Psychological and psychosocial determinants of COVID Health Related Behaviours (COHeRe): An evidence and gap map.

Background: The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has resulted in illness, deaths and societal disruption on a global scale. Societies have implemented various control measures to reduce transmission of the virus and mitigate its impact. Individual behavioural changes are crucial to the successful implementation of these measures. Common recommended measures to limit risk of infection include frequent handwashing, reducing the frequency of social interactions and the use of face coverings. It is important to identify those factors that can predict the uptake and maintenance of these protective behaviours. Objectives: We aimed to identify and map the existing evidence (published and unpublished) on psychological and psychosocial factors that determine uptake and adherence to behaviours aimed at reducing the risk of infection or transmission of COVID-19. Search Methods: Our extensive search included electronic databases (n = 12), web searches, conference proceedings, government reports, other repositories including both published peer reviewed, pre-prints and grey literature. The search strategy was built around three concepts of interest including (1) context (terms relating to COVID-19), (2) behaviours of interest and (3) terms related to psychological and psychosocial determinants of COVID Health-Related Behaviours and adherence or compliance with recommended behaviours, to capture both malleable and non-malleable determinants (i.e. determinants that could be changed and those that could not). Selection Criteria: This Evidence and Gap Map (EGM) includes all types of studies examining determinants of common recommended behaviours aimed at mitigating human-to-human spread of COVID-19. All potential malleable and non-malleable determinants of one or more behaviours are included in the map. As part of the mapping process, categories are used to group determinants. The mapping categories were based on a previous rapid review by Hanratty 2021. These include: 'behaviour', 'cognition', 'demographics', 'disease', 'emotions', 'health status', 'information', 'intervention', and 'knowledge'. Those not suitable for categorisation in any of these groups are included in the map as 'other' determinants. Data Collection and Analysis: Results were imported to a bibliographic reference manager where duplications of identical studies gathered from multiple sources were removed. Data extraction procedures were managed in EPPI-Reviewer software. Information on study type, population, behaviours measured and determinants measured were extracted. We appraised the methodological quality of systematic reviews with AMSTAR-2. We did not appraise the quality of primary studies in this map. Main Results: As of 1 June 2022 the EGM includes 1034 records reporting on 860 cross-sectional, 68 longitudinal, 78 qualitative, 25 reviews, 62 interventional, and 39 other studies (e.g., mixed-methods approaches). The map includes studies that measured social distancing (n = 487), masks and face coverings (n = 382), handwashing (n = 308), physical distancing (n = 177), isolation/quarantine (n = 157), respiratory hygiene/etiquette (n = 75), cleaning surfaces (n = 59), and avoiding touching the T-zone (n = 48). There were 333 studies that assessed composite measures of two or more behaviours. The largest cluster of determinants was 'demographics' (n = 730 studies), followed by 'cognition' (n = 496 studies) and determinants categorised as 'other' (n = 447). These included factors such as 'beliefs', 'culture' and 'access to resources'. Less evidence is available for some determinants such as 'interventions' (n = 99 studies), 'information' (n = 101 studies), and 'behaviour' (149 studies). Authors' Conclusions: This EGM provides a valuable resource for researchers, policy-makers and the public to access the available evidence on the determinants of various COVID-19 health-related behaviours. The map can also be used to help guide research commissioning, by evidence synthesis teams and evidence intermediaries to inform policy during the ongoing pandemic and potential future outbreaks of COVID-19 or other respiratory infections. Evidence included in the map will be explored further through a series of systematic reviews examining the strength of the associations between malleable determinants and the uptake and maintenance of individual protective behaviours.

Perception versus reality: analysis of time spent on bedside rounds in an academic ICU (Intensive Care Unit).

BACKGROUND: Despite its importance, teaching at the bedside is declining over time. This purported decline has not been quantified. Quantifying bedside teaching is challenging, and we found only one study quantifying bedside teaching on a hospitalist service. OBJECTIVE: We conducted a study to understand the prevalence of bedside teaching in our medical intensive care unit. METHODS: We conducted a single-center single-unit study in the medical intensive care unit of an academic tertiary care institution. We used a survey tool to assess perceived time spent on bedside teaching, quality of teaching, and total rounding time. In parallel, independent observers objectively measured time spent on rounds and on bedside teaching. Residents were asked to complete the survey once a week. Independent observers collected data daily and weekly averages were obtained. RESULTS: 43 responses were collected over a 4-month period. Most respondents (73%) reported a total rounding time of either 90-120 min or greater than 120 min. Median reported bedside teaching time was 16-20 min with 16 respondents (37%) reporting less than 15 min and 27 respondents (63%) reporting 16 min or more. The amount of time spent on bedside teaching was reported as adequate or more than adequate by 77% (33) of respondents with 58% (25) reporting that bedside teaching was very or extremely effective in helping them learn. Mean census reported by the independent observers was 12.75 patients per team. Bedside teaching represented an average of 12% of total rounding time, 16.85 min per day. While total rounding time increased with increasing census, there was no decline in bedside teaching time. CONCLUSION: It is reported that bedside teaching has decreased over time. Our study has demonstrated that bedside teaching occurs in our Medical ICU, and though it represents a minority of the time spent on rounds, residents still reported teaching in the ICU to be adequate.

Transgender and Gender Diverse Patients in Intensive Mood Disorder Treatment: A Comparative Examination of Clinical Presentation and Treatment Outcomes.

Individuals who are transgender and gender diverse (TGD) are more likely to suffer from and to seek mental health services for mood disorders. Some literature suggests that TGD individuals, because of pervasive and systemic minority stress, may have more complex clinical presentations (i.e., psychiatric conditions and severity of symptoms) and may benefit from empirically based treatments to a lesser degree than their cisgender peers. However, research has yet to examine individuals who are TGD receiving treatment in specialized, intensive mood disorder treatment despite the propensity for them to be diagnosed with and treated for mood disorders. Using a sample of 1,326 adult patients in intensive mood disorder treatment (3.8% TGD), the clinical presentation and treatment outcomes were compared between patients who are TGD and cisgender. Contrary to previous research, TGD patients were largely similar if not healthier than their cisgender counterparts, including similar depression severity, quality of life, emotion dysregulation, and behavioral activation, and less severe rumination at admission. Despite similar to better reported mental health symptoms, TGD patients were diagnosed with more psychiatric conditions overall, including greater prevalence of social anxiety and neurodevelopmental diagnoses. Those who are TGD did not experience attenuated treatment response as predicted. Findings suggest that patients in intensive mood disorder treatment who are TGD may be more resilient than previously assumed, or supports may have increased to buffer effects of stigma on mental health, and emphasize the need to exercise discretion and sensitivity in diagnostic practices to prevent over-diagnosis and pathologizing of TGD individuals.

Personal and professional influences on health visitors' family focused practice for maternal mental illness: a cross sectional study.

BACKGROUND: Family focused practice (FFP) is an approach that recognises the inter-related needs of family members and recommends a continuum of activities to support families. While it is recognised that health visitors play a key role in supporting families when mothers have mental illness, there is limited understanding of health visitor's family focused practice (FFP) in this context and its relationships with factors, such as, workload, training, skill and knowledge, and personal and professional experience. This paper examined the effect of health visitors' interaction with the family, and personal and professional experience on their family focused practice. METHODS: A cross sectional questionnaire (Family Focused Mental Health Practice Questionnaire) was distributed to 488 health visitors within community practice in Northern Ireland, with 230 choosing to take part. Independent t-tests and one-way analysis of variance were used to compare family focused practice scores. RESULTS: Results found that health visitors who had face to face contact with partners and children (t(221) = 2.61, p = .01), and those that directly supported the partner (t(221) = 2.61, p = 0.01) had a significantly higher mean score of FFP, than those that did not. However, frequency of visits (daily, weekly, monthly or yearly) had no effect on family focused practice scores. Training also had a significant effect on family focused practice scores (F(2,221) = 4.841, p = 0.029). Analysis of variance revealed that personal experience of mental illness had a significant effect on scores (M = 97.58, p = 0.009), however variables such as, age, parental status, time since registration, and being in a specialist position had no effect. CONCLUSIONS: In order for family focused practice to be effective, the quality, and content of visits and contact with family should be addressed, as opposed to a focus on the quantity of visits. However, in order for this to occur health visitors need to have appropriate support in their own right, with manageable caseloads and resources.

The impact of a telemedicine intervention on home non-invasive ventilation in a rural population with advanced COPD.

INTRODUCTION: Rural regions have unique challenges with the implementation of new therapies upon discharge from the hospital due to multiple barriers. OBJECTIVES: We investigated the effect of home non-invasive ventilation (NIV) plus the implementation of a call center following hospitalization for acute exacerbations of COPD (chronic obstructive lung disease) on NIV usage and readmissions. METHODS: In this prospective pilot study, consecutive patients were screened at our institution for diagnosis of hypercarbic respiratory failure or COPD exacerbation from 2018 to 2019. Patients with more than two admissions in the last year were reviewed for eligibility. Of the 82 patients screened, 22 were eligible. There were 10 participants randomized to the intervention (NIV and call center) arm and 10 to NIV alone. RESULTS: A total of 20 patients were randomized (mean age of 64, 45% males, BMI of 32). At three months, average usage was 32.1 days out of 90, 35%. When comparing the call center group to the standard group, there was a statistically significant difference in total days of device usage 48.7 compared to 15.5 (significant U-value of 16, critical value of U at p<.05 of 27) and cumulative use in hours 284 versus 87.7 (significant U-value of 20). Participants in the call center group were readmitted on average 4.2 times compared to 2.4 in the control group which was not statistically different (non-significant U-value of 42). In the follow-up period, 9/20 (45%) of the participants died. CONCLUSION: This pilot study highlights the challenges in implementing care for advanced COPD in a rural population. Our data suggest that telemedicine may favorably address therapy adherence.

Effectiveness of family-focused home visiting for maternal mental illness: A systematic review and meta-analysis.

WHAT IS KNOWN ON THE SUBJECT?: Maternal mental illness reduces a mothers' ability to bond with their infant and may adversely affect other family members. Family-focused practice is an approach which has the potential to support mothers with mental illnesses and reduce the risk of familial transmission of mental illness to children. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: Findings suggest that current interventions are not effective in reducing depression or stress among mothers. The majority of interventions included in this review employed relatively low levels of family-focused practice. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: While there is a growing integration of family-focused practice into home visiting guidelines, this may be based on poor evidence. There is a need for the development of rigorously tested interventions which seek to include the whole family. ABSTRACT: Introduction The evidence on effectiveness of family-focused home visiting for maternal mental illness has yet to be comprehensively synthesized. Aim The aim of this study was to assess current home visiting treatments and interventions for mothers with mental illness and their families. Method The primary and secondary outcomes of interest were depression and maternal stress, respectively, both were included in meta-analyses. We identified 13 (n = 5,540 participants) studies which met inclusion criteria. Eight studies were included in meta-analyses; five studies were reported narratively. Results Findings from the meta-analysis suggest that home visiting interventions are not effective in reducing depression (SMD -0.13, 95% CI -0.33 to 0.07, p = .21) and maternal stress (MD 0.59, 95% CI -5.19 to 6.38, p = .84). Discussion and Implications for practice Findings suggest that current interventions are not effective in reducing depression or stress among mothers. While there is a growing integration of family-focused practice into home visiting guidelines, this may be based on poor evidence.

The effects of depression on the treatment of OCD in a residential sample.

Studies investigating the impact of depressive symptoms on obsessive-compulsive disorder (OCD) treatment have yielded mixed findings. The purpose of the study is to extend previous research, which primarily used outpatient samples, to determine whether depression affects OCD treatment outcome among patients receiving intensive residential treatment. OCD patients receiving residential treatment based primarily on exposure and response prevention (ERP) provided data regarding symptoms of depression and OCD at admission and discharge. Patients reported large and significant reductions in OCD symptoms over the course of treatment. Change in OCD symptoms was not significantly affected by depressive symptoms, including patients with severe depressive symptoms. Change in depressive symptoms over the course of treatment was, however, robustly related to change in OCD symptoms, especially among patients who began treatment with severe symptoms of depression. These findings suggest that cognitive-behavior therapy delivered in a residential treatment setting drastically reduces OCD symptoms regardless of depressive symptoms.

Refractory Acute Respiratory Distress Syndrome Secondary to COVID-19 Successfully Extubated to Average Volume-assured Pressure Support Non-invasive Ventilator.

Coronavirus disease 2019 (COVID-19) is a respiratory illness caused by the highly infectious novel SARS-CoV-2 coronavirus spread by droplet transmission. Consequently, the use of respiratory devices that may potentially promote aerosolization like non-invasive positive pressure ventilation (NIPPV) for diseases such as obstructive sleep apnea (OSA), advanced chronic obstructive lung disease, pulmonary hypertension (PH), and neuromuscular respiratory disease has been called into question. We present a case of a patient with history of OSA and PH convalescing from refractory acute respiratory distress syndrome (ARDS) secondary to COVID-19 who was successfully extubated to average volume-assured pressure support (AVAPS). A 74-year-old male with medical history notable for OSA on NIPPV, PH, and hypertension presented with respiratory failure secondary to COVID-19 confirmed on polymerase chain reaction (PCR) test. His respiratory status worsened leading to ARDS requiring intubation. He was initially extubated to high flow nasal cannula (HFNC) due to hospital policy to avoid NIPPV due to concerns of viral dissemination. He did not tolerate HFNC and required re-intubation for prolonged period. He was then medically optimized for a second attempt and extubated two days later to AVAPS with an anti-viral filter and negative pressure room with a goal of optimizing his critical illness myopathy and pre-existing OSA and PH. He tolerated extubation well, and over the next five days was weaned from alternating AVAPS/HFNC to eventually requiring two liters nasal cannula in the day and AVAPS mode at night. This case highlights a potential therapeutic option for patients with severe respiratory failure secondary to COVID-19. This patient's pre-existing comorbidities of OSA and PH markedly increased his risk for extubation failure on HFNC. The use of AVAPS after his second extubation attempt helped ensure ventilation and oxygenation non-invasively. COVID-19 can lead to prolonged dependence on mechanical ventilation. This pandemic has the potential to create medical resource scarcities, especially in rural areas where ventilators and trained personnel are already in short supply. By using AVAPS mode, this patient was able to rehabilitate his myopathy and participate in intermittent weaning of HFNC to ultimately simple nasal cannula. AVAPS is useful tool to facilitate extubation, as it allows non-invasive support of respiratory dynamics, particularly in those with co-morbidities such as OSA and PH. Further, larger scale studies are needed to determine its exact role during the COVID-19 pandemic.

Predictors of family focused practice among health visitors: A mixed methods study.

AIMS: To determine what predicts health visitors' family-focused practice with mothers who have mental illness. To explore health visitors' experiences of family-focused practice and what factors, if any, enable and/or hinder it. DESIGN: A sequential mixed-methods design was employed. METHODS: In Phase 1, a total of 230 health visitors, in five Health and Social Care Trusts in the UK were recruited using convenience sampling and completed the Family Focused Mental Health Practice Questionnaire. Three multiple regression models were developed to test whether workload (Model I), professional knowledge (Model II) and health visitors' professional and personal experience (Model III) predicted their family-focused practice. In Phase 2, 10 health visitors, who completed the questionnaire, participated in semi-structured interviews to describe their experiences of family-focused practice. The data collection of the two phases was conducted from September 2017 - September 2018. RESULTS: Model III was significant. While personal experience of parenting was positively associated with family-focused practice, length registered as a health visitor and personal experience of mental illness was negatively associated. Qualitative findings suggested that increasing years of professional experience and personal experience of mental illness enabled health visitors to support mothers and their children, but not other adult family members, including partners. Limited skills and knowledge to support mothers with severe mental illness (i.e. schizophrenia) hindered family-focused practice. CONCLUSION: This study advances understanding of how health visitors' professional and personal experiences can influence their family-focused practice and highlights the importance of organizations promoting their capacity to support mothers with severe mental illness and to include mothers' partners. IMPACT: A clear understanding of factors affecting health visitors' capacity to engage in family-focused practice will help to inform policy, education and practice in health visiting; with potential to improve outcomes for the whole family.

Coal mining and lung disease in the 21st century.

PURPOSE OF REVIEW: To review the impact of coal mining and resurgence of coal workers' pneumoconiosis (CWP) in 21st century and effect of ambient air pollution on lung function. RECENT FINDINGS: At the beginning of 21st century, statistics by National Institute for Occupational Safety and Health showed a steep rise in pneumoconiosis. This was followed by numerous epidemiologic and pathologic studies that confirmed increasing CWP prevalence as well as disease in younger miners and those with a shorter mining tenure. Recent studies have demonstrated that poor dust control in mines, a relative shift in composition of the coal mine dust, small sized mines and increase in surface mining are all possible contributors to this resurgence. There is also growing literature evaluating the effects of worsening air pollution on health, including decreasing lung function and development of emphysema, worsening quality of life measures and lung cancer. SUMMARY: This irreversible but preventable disease currently haunts approximately 60 000 miners across United States and millions across the world. Its resurgence despite the strict dust regulations is a setback from the public health standpoint. The continued reliance on coal for energy will continue to place coal miners at danger of developing disease as well as the world.

Behavioral Activation as a Mechanism of Change in Residential Treatment for Mood Problems: A Growth Curve Model Analysis.

Research on the efficacy, effectiveness, and dissemination potential of behavioral activation (BA)-focused interventions for depression and comorbid disorders has expanded rapidly. However, research that examines how BA interventions work has seen less growth. A primary purported mechanism of BA is activation, which reflects a person's meaningful (re)engagement in life. BA theory posits that depression will decrease as activation increases, and that changes in the mechanism variable will lead to changes in outcome. The current study aims to investigate activation as a potential mechanism of change in the context of a BA-focused residential treatment intervention for mood problems using repeated measures of self-reported activation and depression from a large comorbid sample (N = 578). Growth curve modeling was used to examine between-person differences in within-person change over time. Findings suggest that self-reported activation increases and depression decreases over time. Moreover, results show both linear and quadratic growth and that the rate of change in activation predicts the rate of change of depression. BA-focused residential treatment may facilitate activation, which exerts an effect on depression among residents with diagnostically complex presentations.

Predictors of concurrent depressive symptoms in patients with obsessive-compulsive disorder.

Many patients with obsessive-compulsive disorder (OCD) exhibit concurrent depressive symptoms, which are associated with negative psychological outcomes. Yet little research has focused on identifying factors that predict depressive symptoms in OCD. The current study examined three transdiagnostic constructs-anxiety sensitivity (AS), intolerance of uncertainty (IU), and worry-as predictors of depressive symptom severity in a sample of treatment-seeking adults with a primary diagnosis of OCD (N = 93). Strong, positive associations between depressive symptoms and measures of AS, IU, and worry were detected, and AS and worry (but not IU) remained significant unique predictors of depression after controlling for the severity of OCD symptoms. The conceptual and clinical implications of these findings, as well as study limitations and future directions, are discussed.
