Cortisol and C-reactive protein (CRP) regulation in severe mental disorders.

Background: People with schizophrenia (SZ) and bipolar disorder (BD) show abnormalities in the biological stress system and low-grade inflammation. However, whether the hypothalamic-pituitary-adrenal (HPA) axis-immune regulation is disrupted in SZ and BD, is yet to be determined.

Methods: Cortisol and C-reactive protein (CRP) were measured in blood samples collected at or before 10 am in participants with SZ (N = 257), BD (N = 153), and healthy controls (N = 40).

Treatment and counselling preferences of postpartum women with and without symptoms of (childbirth-related) PTSD: findings of the cross-sectional study INVITE.

Background: Post-traumatic stress disorder (PTSD) in the postpartum period is a prevalent yet under-researched mental health condition. To date, many women who suffer from postpartum PTSD remain unrecognized and untreated. To enhance the accessibility of help for these women, it is crucial to offer tailored treatment and counselling services that align with their needs.

Nutritional quality and climate impact of Norwegian adults' diet classified according to the NOVA system.

Information about how ultra-processed foods (UPF) contribute to the intake of energy and nutrients and environmental impact is important for future food policies and dietary recommendations. This study assessed the contribution of the four NOVA food groups, including UPF, to energy intake, nutritional quality, and climate impact in Norwegian adults' diet. We used dietary data from 348 participants in the Norkost 4 pilot study, collected through two non-consecutive 24-h dietary recalls.

Possible scenarios for the spread of mpox outside the endemic focus in Africa.

The recent expansion of mpox in Africa is characterized by a dramatic increase in zoonotic transmission (clade Ia) and the emergence of a new clade Ib that is transmitted from human-to-human (H2H) by close contact. Clade Ia does not pose a threat in areas without zoonotic reservoir. But clade Ib may spread widely, as did the clade IIb that since 2022 has spread globally among MSM.

Minimizing patient burden in outcome monitoring: The case for abbreviated versions of PHQ-9, GAD-7 and WSAS.

Background: The Improving Access to Psychological Therapies (IAPT) program uses the Patient Health Questionnaire (PHQ-9), the Generalized Anxiety Disorder Scale (GAD-7), and the Work and Social Adjustment Scale (WSAS) as part of their unique outcome monitoring system. To reduce patient burden, this study explored whether abbreviated versions of these questionnaires can be used to derive relevant outcome statistics with minimal loss of information.

Methods: Using two samples (training; n = 1530, validation; n = 766), we examined whether existing short-forms, PHQ-4 and GAD-R3, would provide enough information to calculate relevant outcomes with near perfect agreement with the outcomes based on the original scales.

Monitoring Chronic Non-Cancer Pain in Denmark Over Two Decades: Prevalence, Mental Health and Loneliness.

Background: Epidemiological surveys have monitored chronic non-cancer pain (CNCP) and investigated associated factors in Denmark for more than 20 years. This study aimed to analyse CNCP prevalence in the Danish population from 2000 to 2023 and its associations with mental health status and loneliness.

Methods: Population-based surveys were conducted between 2000 and 2023.

Hazard assessment of nanomaterials: how to meet the requirements for (next generation) risk assessment.

Background: Hazard and risk assessment of nanomaterials (NMs) face challenges due to, among others, the numerous existing nanoforms, discordant data and conflicting results found in the literature, and specific challenges in the application of strategies such as grouping and read-across, emphasizing the need for New Approach Methodologies (NAMs) to support Next Generation Risk Assessment (NGRA). Here these challenges are addressed in a study that couples physico-chemical characterization with in vitro investigations and in silico similarity analyses for nine nanoforms, having different chemical composition, sizes, aggregation states and shapes. For cytotoxicity assessment, three methods (Alamar Blue, Colony Forming Efficiency, and Electric Cell-Substrate Impedance Sensing) are applied in a cross-validation approach to support NAMs implementation into NGRA.

A Mechanistic Approach to Optimize Combination Antibiotic Therapy.

Antimicrobial resistance is one of the most significant healthcare challenges of our times. Multidrug or combination therapies are sometimes required to treat severe infections; for example, the current protocols to treat pulmonary tuberculosis combine several antibiotics. However, combination therapy is usually based on lengthy empirical trials, and it is difficult to predict its efficacy.

Sex differences in childhood cancer risk following ART conception: a registry-based study.

Study Question: Does the risk of childhood cancer following ARTs vary by sex?

Summary Answer: In this registry-based study, some childhood cancers showed positive sex- and age-specific associations in children conceived using certain ART modalities, which were not evident in overall combined analyses.

What Is Known Already: The relationship between ART and risk of childhood cancer has shown diverse outcomes in prior research. Studies examining whether there are sex differences in childhood cancer risk after ART conception are lacking.

Time trends and birth rates in women with congenital heart disease; a nationwide cohort study from Norway 1994-2014.

Background: More women with congenital heart disease (CHD) reach reproductive age, but little is known of their success in having children. We investigated time trends of CHD in women of reproductive age and maternal CHD in childbirth and compared birth rates in women with CHD to birth rates in women without heart disease.

Methods And Results: In a national cohort, we combined information from five registries in Norway 1994-2014.

Implementation of a parent training intervention (SPARCK) to prevent childhood mental health problems: study protocol for a pragmatic implementation trial in Norwegian municipalities.

Background: Effective evidence-based interventions (EBI) are necessary to prevent and avoid negative life trajectories for children with mental health problems. Even though many EBIs prove effective when tested, few are successfully implemented and used in real-world clinical practice. As a result, many children and families do not receive the best care in due time or at all.

Process Evaluation of Teaching Critical Thinking About Health Using the Informed Health Choices Intervention in Uganda: A Mixed Methods Study.

Introduction: We designed the Informed Health Choices (IHC) secondary school intervention and evaluated whether it improves students' ability to assess the trustworthiness of claims about treatment effects in Uganda. We conducted a process evaluation alongside a randomized trial to identify factors that may affect the implementation, fidelity, and scaling up of the intervention in Uganda. We also explored the potential adverse and beneficial effects of the intervention.

Process Evaluation of Teaching Critical Thinking About Health Using the Informed Health Choices Intervention in Kenya: A Mixed Methods Study.

Introduction: We evaluated the Informed Health Choices secondary school intervention to help students in Kenya think critically about health choices. We conducted this process evaluation to explore if the intervention was implemented as planned, identify factors that facilitated or hindered implementation, potential benefits of the intervention, and how to scale up the intervention beyond the trial.

Methods: This was a mixed methods process evaluation nested in a cluster-randomized trial of the Informed Health Choices intervention.

Process Evaluation of Teaching Critical Thinking About Health Using the Informed Health Choices Intervention in Rwanda: A Mixed Methods Study.

Introduction: We evaluated the Informed Health Choices secondary school intervention in a cluster randomized trial in Rwanda. The intervention was effective in helping students to think critically about health. In parallel to the trial, we conducted a process evaluation to assess factors affecting the implementation, impacts, and scale-up of the intervention.

Exercise therapy for chronic fatigue syndrome.

Background: Chronic fatigue syndrome (CFS) or myalgic encephalomyelitis (ME) is a serious disorder characterised by persistent postexertional fatigue and substantial symptoms related to cognitive, immune and autonomous dysfunction. There is no specific diagnostic test, therefore diagnostic criteria are used to diagnose CFS. The prevalence of CFS varies by type of diagnostic criteria used.

Evaluating causal associations of chronotype with pregnancy and perinatal outcomes and its interactions with insomnia and sleep duration: a mendelian randomization study.

Background: Observational studies suggested chronotype was associated with pregnancy and perinatal outcomes. Whether these associations are causal is unclear. Our aims are to use Mendelian randomization (MR) to explore (1) associations of evening preference with stillbirth, miscarriage, gestational diabetes, hypertensive disorders of pregnancy, perinatal depression, preterm birth and offspring birthweight; and (2) differences in associations of insomnia and sleep duration with those outcomes between chronotype preferences.

MinLinMo: a minimalist approach to variable selection and linear model prediction.

Generating prediction models from high dimensional data often result in large models with many predictors. Causal inference for such models can therefore be difficult or even impossible in practice. The stand-alone software package MinLinMo emphasizes small linear prediction models over highest possible predictability with a particular focus on including variables correlated with the outcome, minimal memory usage and speed.

Telomere length in relation to fecundability and use of assisted reproductive technologies: the Norwegian Mother, Father, and Child Cohort Study.

Background: Telomere length (TL) has been reported to be associated with conditions such as endometriosis and polycystic ovary syndrome, with some studies finding associations with shorter TL and others with longer TL. In men, studies mostly report associations between shorter TL and sperm quality. To our knowledge, no studies have thus far investigated associations between TL and fecundability or the use of assisted reproductive technologies (ART).

Potentially traumatic events and the association with hazardous alcohol use in 19,128 middle aged and elderly adults: the Tromsø Study 2015-2016.

Purpose: The aim was to examine the association between a wide range of potentially traumatic events (PTEs) experienced in childhood, adulthood or both, and hazardous alcohol use, including the relationship between the total sum of PTEs and hazardous alcohol use in middle aged and elderly adults. Previous studies have predominantly focused on childhood PTEs or isolated PTEs and more severe alcohol problems, little focus has been given to middle aged and elderly adults with hazardous alcohol use and PTE experiences.

Methods: We used logistic regression analysis to study the relation between a broad range of PTEs and hazardous alcohol defined by the alcohol use disorder identification test (AUDIT) in 19,128 women and men aged 40 years and above participating in the seventh survey of the Norwegian population-based Tromsø Study in 2015-2016.

From trials to practice: Immune checkpoint inhibitor therapy for melanoma patients in Norway.

Background And Purpose: Norway has one of the highest rates of cutaneous melanoma (CM) incidence and mortality globally. Immune checkpoint inhibitor (ICI) therapy for CM was introduced between 2014 and 2017 to improve treatment and patient prognosis, but knowledge about its clinical usage is limited. This study investigates patient's characteristics and treatment patterns in real-world practice compared to clinical trial results.

Socioeconomic and geographic variation in adjuvant chemotherapy among elderly patients with stage III colon cancer in Norway - a national register-based cohort study.

Background: About half of the patients diagnosed with colon cancer are 70 years or older. Standard treatment for stage III colon cancer is major surgical resection followed by adjuvant chemotherapy (ACT). Norwegian guidelines recommend initiation of ACT within 6 weeks after resection.

Prevalence of substance use disorder diagnoses in patients with chronic pain receiving reimbursed opioids: An epidemiological study of four Norwegian health registries.

Objectives: Since 2008, patients have had access to reimbursed analgesics, including opioids, for chronic pain in Norway. There is a need for knowledge on the occurrence and trends over time of substance use disorder (SUD) diagnoses among patients who receive reimbursed opioids for chronic pain. The primary aim of this study was to investigate the prevalence of SUD diagnoses in patients with chronic pain using reimbursed opioids from 2010 to 2019 in Norway.
