Background The death of a parent is a highly stressful life event for bereaved children. Several studies have shown an increased risk of mental ill-health and psychosocial problems among affected children. The aims of this study were to systematically review studies about effective support interventions for parentally bereaved children and to identify gaps in the research. Methods The review’s inclusion criteria were comparative studies with samples of parentally bereaved children. The focus of these studies were assessments of the effects on children of a bereavement support intervention. The intervention was directed towards children 0–18 years; but it could also target the children’s remaining parent/caregiver. The study included an outcome measure that dealt with effects of the intervention on children. The following electronic databases were searched up to and including November 2015: PubMed, PsycINFO, Cinahl, PILOTS, ProQuest Sociology (Sociological Abstracts and Social Services Abstracts). The included studies were analysed and summarized based on the following categories: type of intervention, reference and grade of evidence, study population, evaluation design, measure, outcome variable and findings as effect size within and between groups. Results One thousand, seven hundred and-six abstracts were examined. Following the selection process, 17 studies were included. The included studies consisted of 15 randomized controlled studies, while one study employed a quasi-experimental and one study a pre-post-test design. Thirteen studies provided strong evidence with regards to the quality of the studies due to the grade criteria; three studies provided fairly strong evidence and one study provided weaker evidence. The included studies were published between 1985 and 2015, with the majority published 2000 onwards. The studies were published within several disciplines such as psychology, social work, medicine and psychiatry, which illustrates that support for bereaved children is relevant for different professions. The interventions were based on various forms of support: group interventions for the children, family interventions, guidance for parents and camp activities for children. In fourteen studies, the interventions were directed at both children and their remaining parents. These studies revealed that when parents are supported, they can demonstrate an enhanced capacity to support their children. In three studies, the interventions were primarily directed at the bereaved children. The results showed positive between group effects both for children and caregivers in several areas, namely large effects for children’s traumatic grief and parent’s feelings of being supported; medium effects for parental warmth, positive parenting, parent’s mental health, grief discussions in the family, and children’s health. There were small effects on several outcomes, for example children’s post-traumatic stress disorder (PTSD) symptoms, anxiety, depression, self-esteem and behaviour problems. There were studies that did not show effects on some measures, namely depression, present grief, and for the subgroup boys on anxiety, depression, internalizing and externalizing. Conclusions The results indicate that relatively brief interventions can prevent children from developing more severe problems after the loss of a parent, such as traumatic grief and mental health problems. Studies have shown positive effects for both children’s and remaining caregiver’s health. Further research is required including how best to support younger bereaved children. There is also a need for more empirically rigorous effect studies in this area.

The study aim was to explore the use of an Intensive Care Unit (ICU) diary within four different ICUs units in Sweden and thereby contribute to practice guidelines regarding the structure, content and use of an ICU diary. ICU diaries are used to aid psychological recovery among critical care patients, but differences remain in diary writing both within and across countries. Few studies have focused on the combined views and experiences of ICU patients, family members and nursing staff about the use of ICU diaries. An instrumental multiple case study design was employed. Three focus groups interviews were carried out with 8 former patients and their family members (n = 5) from the research settings. Individual interviews were carried out with 2 patients, a family member and a nurse respectively. Observations, field notes, documentary analysis and conversations with nursing staff were also conducted. Consolidated criteria for reporting qualitative research (COREQ) was followed. The qualitative findings firstly consisted of a matrix and descriptive text of the four ICU contexts and current practices. This highlighted that there were similarities regarding the aims and objectives of the diaries. However, differences existed across the case study sites about how the ICU diary was developed and implemented. Namely, the use of photographs and when to commence a diary. Second, a thematic analysis of the qualitative data regarding patients' and family members' use of the ICU diary, resulted in four themes: i) the diary was used to take in and fully understand the situation; ii) the diary was an opportunity to assimilate warm, personalised and human care; iii) the diary was used to manage existential issues; and iv) the diary was a tool in daily activities. Analysis of the instrumental case study data led to the identification of core areas for inclusion in ICU diary practice guidelines.

Narcolepsy type 1 is caused by severe loss or lack of brain orexin neuropeptides. We conducted a phase 2, randomized, placebo-controlled trial of TAK-994, an oral orexin receptor 2-selective agonist, in patients with narcolepsy type 1. Patients with confirmed narcolepsy type 1 according to clinical criteria were randomly assigned to receive twice-daily oral TAK-994 (30 mg, 90 mg, or 180 mg) or placebo. The primary end point was the mean change from baseline to week 8 in average sleep latency (the time it takes to fall asleep) on the Maintenance of Wakefulness Test (range, 0 to 40 minutes; normal ability to stay awake, ≥20 minutes). Secondary end points included the change in the Epworth Sleepiness Scale (ESS) score (range, 0 to 24, with higher scores indicating greater daytime sleepiness; normal, <10) and the weekly cataplexy rate. Of the 73 patients, 17 received TAK-994 at a dose of 30 mg twice daily, 20 received 90 mg twice daily, 19 received 180 mg twice daily, and 17 received placebo. The phase 2 trial and an extension trial were terminated early owing to hepatic adverse events. Primary end-point data were available for 41 patients (56%); the main reason for missing data was early trial termination. Least-squares mean changes to week 8 in average sleep latency on the MWT were 23.9 minutes in the 30-mg group, 27.4 minutes in the 90-mg group, 32.6 minutes in the 180-mg group, and -2.5 minutes in the placebo group (difference vs. placebo, 26.4 minutes in the 30-mg group, 29.9 minutes in the 90-mg group, and 35.0 minutes the 180-mg group; P<0.001 for all comparisons). Least-squares mean changes to week 8 in the ESS score were -12.2 in the 30-mg group, -13.5 in the 90-mg group, -15.1 in the 180-mg group, and -2.1 in the placebo group (difference vs. placebo, -10.1 in the 30-mg group, -11.4 in the 90-mg group, and -13.0 in the 180-mg group). Weekly incidences of cataplexy at week 8 were 0.27 in the 30-mg group, 1.14 in the 90-mg group, 0.88 in the 180-mg group, and 5.83 in the placebo group (rate ratio vs. placebo, 0.05 in the 30-mg group, 0.20 in the 90-mg group, and 0.15 in the 180-mg group). A total of 44 of 56 patients (79%) receiving TAK-994 had adverse events, most commonly urinary urgency or frequency. Clinically important elevations in liver-enzyme levels occurred in 5 patients, and drug-induced liver injury meeting Hy's law criteria occurred in 3 patients. In a phase 2 trial involving patients with narcolepsy type 1, an orexin receptor 2 agonist resulted in greater improvements on measures of sleepiness and cataplexy than placebo over a period of 8 weeks but was associated with hepatotoxic effects.

Informal carers in paid employment-working carers (WKCs)-have complex support needs. However, little is known about WKCs' pattern of informal care provision, the support they receive, the impact providing care has on their employment, and how these vary between male and female WKCs. This study describes the pattern of informal care provision and received support among Swedish WKCs. The study was a cross-sectional questionnaire-based survey of a stratified random sample of the Swedish population aged 18 or over. The questionnaire addressed the type and extent of informal care provided, support received and the impact of care provision on employment. Of the 30,009 people who received the questionnaire, 11,168 (37.3%) responded, providing an analytic sample of 818 (7.32% of respondents) employed or self-employed informal carers. A typical Swedish WKC was a middle-aged female, providing weekly or daily care to a non-cohabitant parent, who experiences care as sometimes demanding and receives no formal support as a carer. Female WKCs were more likely than males to care alone and with higher intensity, to report a need for help in meeting their care-recipient's needs, and to experience care as demanding. Approximately 17% of WKCs reported their employment had been affected due to caring, 40% their ability to work, and 31% their career development opportunities. Female WKCs' ability to work was affected more than males', and they were more commonly prevented from applying for work. Swedish female WKCs compared to males provide more hours of informal care, across more care domains, more often alone. This places them in a challenging situation when combining paid work and care. Greater recognition of the challenges faced by WKCs is required in Sweden and other countries, as are policies to reduce gender inequalities in informal care provision in this group.

Background Over the past decades, informal care has increased in most OECD-countries. Informal care is costly to caregivers and to society in the form of lost income and direct costs of providing care. Existing evidence suggests that providing informal care affects caregivers’ overall health. However, estimates of the social costs of informal care based on national data on individuals are currently scarce. Objective This study contributes to the existing evidence on the costs of informal care by estimating the direct and indirect costs to caregivers using a purposive national household survey from Sweden. Methods Adopting a bottom-up, prevalence approach, the direct and indirect costs are estimated using the survey data and the value of working time and leisure time from existing sources. Results The results suggest that around 15% of the adult population of Sweden provide informal care and that such care costs around SEK 152 billion per year (around 3% of GDP; USD 16,3 billion; EUR 14,5 billion), or SEK 128000 per caregiver. Around 55% of costs are in the form of income loss to caregivers. The largest cost items are reduced work hours and direct costs of providing informal care. Replacing informal caregivers with professional care providers would be costly at around SEK 193,6 billion per year. Conclusions Findings indicate that, even in a country with a relatively generous welfare system, significant resources are allocated toward providing informal care. The costing analysis suggests that effective support initiatives to ease the burden of informal caregivers may be cost-effective.

Background Medical schools have undergone a period of continual curricular change in recent years, particularly with regard to pre-clinical education. While these changes have many benefits for students, the impact on faculty is less clear. Methods In this study, faculty motivation to teach in the pre-clinical medical curriculum was examined using self-determination theory (SDT) as a framework. Basic science and clinical faculty were surveyed on factors impacting their motivation to teach using validated scales of motivation as well as open-ended questions which were coded using self-determination theory (SDT) as a guiding framework. Results Faculty reported that teaching activities often meet their basic psychological needs of competence, autonomy, and relatedness. Professors were more likely than associate professors to report that teaching met their need for autonomy. Faculty were more motivated by intrinsic as compared to external factors, although basic science faculty were more likely than clinical faculty to be motivated by external factors. Motivating and de-motivating factors fell into the themes Resources, Recognition and Rewards, Student Factors, Self-Efficacy, Curriculum, Contribution, and Enjoyment . The majority of factors tied to the faculty’s need for relatedness. Based on these findings, a conceptual model for understanding medical school faculty motivation to teach was developed. Conclusions Assessing faculty motivation to teach provided valuable insights into how faculty relate to their teaching roles and what factors influence them to continue in those roles. This information may be useful in guiding future faculty development and research efforts.

Environmental cues and internal states such as mood, reward, or aversion directly influence feeding behaviors beyond homeostatic necessity. The hypothalamus has been extensively investigated for its role in homeostatic feeding. However, many of the neural circuits that drive more complex, non-homeostatic feeding that integrate valence and sensory cues (such as taste and smell) remain unknown. Here, we describe a basal forebrain (BF)-to-lateral habenula (LHb) circuit that directly modulates non-homeostatic feeding behavior. Using viral-mediated circuit mapping, we identified a population of glutamatergic neurons within the BF that project to the LHb, which responds to diverse sensory cues, including aversive and food-related odors. Optogenetic activation of BF-to-LHb circuitry drives robust, reflexive-like aversion. Furthermore, activation of this circuitry suppresses the drive to eat in a fasted state. Together, these data reveal a role of basal forebrain glutamatergic neurons in modulating LHb-associated aversion and feeding behaviors by sensing environmental cues.

The role of transcription factors during astrocyte development and their subsequent effects on neuronal development has been well studied. Less is known about astrocytes contributions towards circuits and behavior in the adult brain. Astrocytes play important roles in synaptic development and modulation, however their contributions towards neuronal sensory function and maintenance of neuronal circuit architecture remain unclear. Here, we show that loss of the transcription factor Sox9 results in both anatomical and functional changes in adult mouse olfactory bulb (OB) astrocytes, affecting sensory processing. Indeed, astrocyte-specific deletion of Sox9 in the OB results in decreased odor detection thresholds and discrimination and it is associated with aberrant neuronal sensory response maps. At functional level, loss of astrocytic Sox9 impairs the electrophysiological properties of mitral and tufted neurons. RNA-sequencing analysis reveals widespread changes in the gene expression profiles of OB astrocytes. In particular, we observe reduced GLT-1 expression and consequential alterations in glutamate transport. Our findings reveal that astrocytes are required for physiological sensory processing and we identify astrocytic Sox9 as an essential transcriptional regulator of mature astrocyte function in the mouse OB. Astrocytes can regulate neuronal activity. Here, the authors show that astrocyte-specific deletion of Sox9 results in impaired neuronal sensory processing in the mouse adult olfactory bulb.

A clear example of recent technological progress is depicted in the article by Morgan et al., in which the authors describe a novel methodological pipeline to integrate confocal fluorescence microscopy with the ultrastructural interrogation of neural circuits by electron microscopy. For functional investigation, a broad and ever-expanding toolkit of viral and genetic techniques has evolved that now allows selective labeling and manipulation of individual neurons and their respective circuits. Using retrograde tracing, Anair et al. describe a new commissural pathway that connects both sides of the inferior colliculus, engaging a GABAergic neuronal population that expresses neuropeptide Y. At the same time, reward-related and motivational processes influence the transformation of sensory input into behavioral output.
