Background: In Norway, the number of people on sick leave and health-related absence from work has increased over the last few years, and mental illness is one of the main contributing factors. Individual Placement and Support (IPS) and the Qualification Program (QP) are two work-oriented measures offered by Norwegian labor and welfare authorities, aimed at increasing labor market participation among people with health-related problems. The aim of this study was to explore which factors people with mental illnesses found helpful for attaining and retaining work, and their experiences with taking part in IPS and the QP.

High heart rate variability (HRV) is increasingly recognized as an indicator of a healthy regulatory system, reflecting the dynamic balance between sympathetic (SNS) and parasympathetic (PSNS) nervous system activity. According to the neurovisceral integration model, this balance is managed by the central autonomic network (CAN), comprised of specific brain regions involved in emotional, attentional, and autonomic regulation. HRV thus reflects the performance of the cognitive, affective, and autonomic regulation system.

Nematodes pose significant challenges for the fish processing industry, particularly in white fish. Despite technological advances, the industry still depends on manual labor for the detection and extraction of nematodes. This study addresses the initial steps of automatic nematode detection and differentiation from other common defects in fish fillets, such as skin remnants and blood spots.

Unlabelled: Bacilli and pseudomonads are among the most well-studied microorganisms commonly found in soil and frequently co-isolated. Isolates from these two genera are frequently used as plant beneficial microorganisms; therefore, their interaction in the plant rhizosphere is relevant for agricultural applications. Despite this, no systematic approach has been employed to assess the coexistence of members from these genera.

Atlantic mackerel () caught during the summer months in Icelandic waters after intensive feeding is rich in lipids and, thus, sensitive to lipid degradation. Recent studies have led to improved cooling and handling on board, ensuring high-quality raw material. However, studies on the development of high-quality products for human consumption are lacking.

Background: Monoclonal gammopathy of undetermined significance (MGUS) is a precursor of multiple myeloma (MM) and related conditions. In previous registry-based, retrospective studies, autoimmune diseases have been associated with MGUS. However, these studies were not based on a screened population and are therefore prone to ascertainment bias.

Background: Monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myeloma (SMM) are asymptomatic precursor conditions to multiple myeloma and related disorders. Smoldering multiple myeloma is distinguished from MGUS by 10% or greater bone marrow plasma cells (BMPC) on sampling, has a higher risk for progression, and requires specialist management.

Objective: To develop a multivariable prediction model that predicts the probability that a person with presumed MGUS has 10% or greater BMPC (SMM or worse by bone marrow criteria) to inform the decision to obtain a bone marrow sample and compare its performance to the Mayo Clinic risk stratification model.

Aim: The aim of this study was to investigate a cohort of Swedish eighth graders' mental health and experiences during the COVID-19 pandemic.

Methods: Participants were 157 eighth graders recruited in junior high schools during 2020 who completed a depression questionnaire and a survey about their psychosocial health in relation to the COVID-19 pandemic, alongside a follow-up assessment in 2021. Analyses were conducted using latent change score and cross-lagged models.

Article Synopsis
  • Nonalcoholic fatty liver disease (NAFLD) is a prevalent chronic liver condition linked with obesity, type 2 diabetes, and metabolic syndrome, which increases cardiovascular disease risk, but lifestyle changes can enhance health outcomes.
  • This study evaluated a 12-week digital health program aimed at improving engagement, retention, and user satisfaction while monitoring health changes related to weight and metabolic factors among individuals with NAFLD, obesity, or diabetes.
  • Among the 38 participants, 89% completed the program, reporting high satisfaction (median score of 6.3/7), with an average weight loss of 3.5 kg and notable improvements in overall metabolic health indicators.

Introduction: The aims of this retrospective study were to investigate the incidence, clinical course and short term outcomes of new-onset postoperative atrial fibrillation (POAF) following coronary artery bypass surgery (CABG).

Materials And Methods: A nation-wide study on 1622 patients who underwent CABG from 2006-2020 at Landspitali University Hospital. Clinical data were extracted from registries and 121 patients with pre-existing AF excluded, leaving 1501 patients for further analysis.

Most of the studies on the effect of trait positive affect (PA) and cardiovascular activity have focused on heart rate (HR) and blood pressure (BP) rather than heart rate variability (HRV). However, trait PA might sustain homeostasis for the autonomic system (ANS) by reducing activity in the sympathetic system (SNS) and increasing the activity in the parasympathetic system (PNS). A common index for the PNS is the vagal tone measured indirectly through HRV.

Background: Job satisfaction is a key factor for the successful transition of newly graduated nurses (NGNs) and for retaining NGNs in their workplaces. However, there is limited evidence of the relationship between satisfaction regarding the nursing education program and NGNs' job satisfaction in the first year after graduation. Therefore, this study aims to examine the association of the nursing education related factors and NGNs' job satisfaction.

Background: Persistent symptoms are common after SARS-CoV-2 infection but correlation with objective measures is unclear.

Methods: We invited all 3098 adults who tested SARS-CoV-2 positive in Iceland before October 2020 to the deCODE Health Study. We compared multiple symptoms and physical measures between 1706 Icelanders with confirmed prior infection (cases) who participated, and 619 contemporary and 13,779 historical controls.

Background: Knowledge is lacking about the effects of COVID-19 on nursing students' burnout symptoms. Burnout can lead to negative feelings and behaviours towards learning and poor mental health.

Aims: To describe and compare nursing/midwifery students' burnout, explore differences and detect predictors at two time points through COVID-19.

The North American Airway Collaborative (NoAAC) previously published a 3-year multi-institutional prospective cohort study showing variation in treatment effectiveness between 3 primary surgical techniques for idiopathic subglottic stenosis (iSGS). In this report, we update these findings to include 5 years of data evaluating treatment effectiveness. Patients in the NoAAC cohort were re-enrolled for 2 additional years and followed using the prespecified published protocol.

Aim: The aim of the study was to test the psychometric properties of the Facilitative Student-Patient Relationship (FSPR) Scale in clinical practicum in hospital settings within six European countries.

Design: A multi-country, cross-sectional survey design was applied.

Methods: A convenience sample of graduating nursing students (N = 1,796) completed the FSPR Scale.

Article Synopsis
  • * Using a genetic model of zebrafish, researchers found that certain non-stimulant drugs could reduce hyperactivity but often interfered with sleep patterns; this includes testing a library of compounds to identify effective alternatives.
  • * They discovered five potential new therapeutics, including moxonidine, which shows promise not only in reducing hyperactivity but also in cognitive effects, hinting at new mechanisms underlying ADHD therapy through imidazoline receptors.

Young adults with mental health conditions want to work and advance their education, but many need help attaining these goals. Individual Placement and Support (IPS), originally developed for working-age adults with serious mental illness, is an evidence-based employment model that may benefit young adults. This study is the first systematic review and meta-analysis of randomized controlled trials (RCTs) of IPS for this population.

Current patterns of meat consumption are considered unsustainable. Plant-based products are presented as a solution. However, while some plant-based products thrive, others do not make the cut due to the information "framing" effect issues related to the way information is presented to the consumers.
