The B Chromosome of Pseudococcus viburni: A Selfish Chromosome that Exploits Whole-Genome Meiotic Drive.

Meiosis is generally a fair process: each chromosome has a 50% chance of being included into each gamete. However, meiosis can become aberrant with some chromosomes having a higher chance of making it into gametes than others. Yet, why and how such systems evolve remains unclear.

Acceptability and Preliminary Effects of Intensive Brief Trauma-Focused PTSD Treatment for Refugees.

Background: Post-Traumatic Stress Disorder (PTSD) is a significant mental health concern in refugee populations exposed to trauma and displacement. Traditional treatments for PTSD often involve lengthy interventions. However, there's a growing interest in exploring more condensed, intensive treatments to improve outcomes and accessibility for refugees.

Children who survive torture: A systematic review of screening, documentation and treatment of torture injuries in children.

Background: Children all over the world are subjected to torture, but few are identified as victims of these actions. Knowledge that facilitates identification, documentation, and treatment of torture injuries in children can allow redress and rehabilitation for more children in need.

Objective: To synthesise research regarding screening, documentation, and treatment of child survivors of torture.

Refractory and Resistant Herpes Simplex Virus Mucocutaneous Infections in Immunocompromised Patients: Literature Review and Proposed Definitions for Use in Clinical Trials.

Herpes simplex virus (HSV) infection is one of the most prevalent viral infections worldwide. In general, host immunity is sufficient to clear viral shedding and recurrences, although it is insufficient to prevent subsequent virologic reactivations. In immunocompromised patients, prolonged and difficult-to-treat HSV infections may develop.

A Prospective Clinical Trial Evaluating the Efficacy and Safety of Non-Animal Stabilized Hyaluronic Acid Injections for Non-Surgical Rhinoplasty.

Non-surgical rhinoplasty with hyaluronic acid (HA) filler is a three-dimensional reshaping technique that achieves tissue enhancement by placing HA deep to nasal skin. Due to its unique rheology, Restylane® Lyft (HA-L, Galderma, Uppsala, Sweden) may be particularly well-suited for injection rhinoplasty, as it has high gel firmness (G') for strong structural support with minimal integration propensity. A prospective clinical trial was conducted to evaluate HA-L use for non-surgical rhinoplasty.

The promise of community-driven preprints in ecology and evolution.

Publishing preprints is quickly becoming commonplace in ecology and evolutionary biology. Preprints can facilitate the rapid sharing of scientific knowledge establishing precedence and enabling feedback from the research community before peer review. Yet, significant barriers to preprint use exist, including language barriers, a lack of understanding about the benefits of preprints and a lack of diversity in the types of research outputs accepted (e.

Management factors affecting milk yield, composition, and quality on smallholder dairy farms.

A cross-sectional study on 156 smallholder dairy farms in Rwanda was carried out to assess the association between farm management practices and milk yield and quality. A pre-tested questionnaire was used to collect data on cow characteristics and farm management practices. Milk yield was recorded at household level, milk composition was monitored using a Lactoscan device (Milk Analyzer).

Associations between common genetic variants and income provide insights about the socio-economic health gradient.

We conducted a genome-wide association study on income among individuals of European descent (N = 668,288) to investigate the relationship between socio-economic status and health disparities. We identified 162 genomic loci associated with a common genetic factor underlying various income measures, all with small effect sizes (the Income Factor). Our polygenic index captures 1-5% of income variance, with only one fourth due to direct genetic effects.

Treatment effect of head extension by cervical collar on moderate obstructive sleep apnea-A randomized controlled trial.

As available treatments in obstructive sleep apnea are all associated with side-effects or adherence problems, there is a need for alternative treatment options. In this randomized, open, parallel-group intervention study, the effect of head extension by cervical collar was evaluated in patients with moderate obstructive sleep apnea. One-hundred patients with moderate obstructive sleep apnea (apneas and hypopneas per estimated hours asleep = respiratory events index: 15-30) were randomized to either lifestyle intervention, or cervical collar in combination with lifestyle intervention.

Capacity and limitations of microfluidic flow to increase solute transport in three-dimensional cell cultures.

Culturing living cells in three-dimensional environments increases the biological relevance of laboratory experiments, but requires solutes to overcome a diffusion barrier to reach the centre of cellular constructs. We present a theoretical and numerical investigation that brings a mechanistic understanding of how microfluidic culture conditions, including chamber size, inlet fluid velocity and spatial confinement, affect solute distribution within three-dimensional cellular constructs. Contact with the chamber substrate reduces the maximally achievable construct radius by 15%.

Review: A systematic review of dairy cow health, welfare, and behaviour in year-round loose range housing.

This systematic review compares the health, welfare, and behaviour of dairy cows in year-round loose housing systems against those kept in other housing systems in temperate regions. Year-round loose housing systems comprised housing where dairy cows had no access to the outdoors or only had access to a yard, pen or run. The comparator housing systems also comprised housing with and without outdoor access (including grazing).

Healthcare professionals' attitudes to animal assisted activity with dogs in paediatric care.

Background: Hospitalization for children often involves stress induced by fear and pain. Complementary therapies, such as Animal Assisted Activities (AAA) with dogs, can alleviate the hospital experience.

Purpose: The first aim of this study was to initiate the development of an instrument that measures healthcare professionals' attitudes toward complementary therapy, specifically dogs in AAA.

Engagement With an Internet-Administered, Guided, Low-Intensity Cognitive Behavioral Therapy Intervention for Parents of Children Treated for Cancer: Analysis of Log-Data From the ENGAGE Feasibility Trial.

Background: Parents of children treated for cancer may experience psychological difficulties including depression, anxiety, and posttraumatic stress. Digital interventions, such as internet-administered cognitive behavioral therapy, offer an accessible and flexible means to support parents. However, engagement with and adherence to digital interventions remain a significant challenge, potentially limiting efficacy.

Exploring the Patients' Perspective on Digital Tools for Psychosocial Assessment in Dentistry.

Background: Psychosocial screening is a valuable part of the assessment of patients with orofacial pain, as psychosocial factors will affect prognosis and treatment outcomes. Paper-based questionnaires are predominately used to assess the degree of psychosocial comorbidity; however, digital alternatives for screening questionnaires may be more cost-effective and resource-saving if patients are receptive to using them.

Objective: To evaluate how patients perceive digital psychosocial screening in dentistry.

This article uses medical textbooks and advice literature to analyze the in the early German Enlightenment. The article pursues three lines of argument. First, it uses medical textbooks to situate the physician in the context of early modern observational life, focusing in particular on , , and for conducting and documenting observations.

I've really struggled but it does not seem to work: adolescents' experiences of living with ADHD - a thematic analysis.

Background: In Attention-deficit/hyperactivity disorder (ADHD) the transition from childhood to adolescence encompass changes in symptom manifestation and related challenges. Given the potential negative impact of ADHD on adolescents, and the increased risk for dropping out from treatment, there is a need to understand more about how adolescents experience their condition. The aim of this study was to explore adolescents' perceptions of how it is to live with ADHD.

A compendium of Amplification-Related Gain Of Sensitivity genes in human cancer.

While the effect of amplification-induced oncogene expression in cancer is known, the impact of copy-number gains on "bystander" genes is less understood. We create a comprehensive map of dosage compensation in cancer by integrating expression and copy number profiles from over 8000 tumors in The Cancer Genome Atlas and cell lines from the Cancer Cell Line Encyclopedia. Additionally, we analyze 17 cancer open reading frame screens to identify genes toxic to cancer cells when overexpressed.

Perspectives on Swedish Regulations for Online Record Access Among Adolescents With Serious Health Issues and Their Parents: Mixed Methods Study.

Background: With the increasing implementation of patient online record access (ORA), various approaches to access to minors' electronic health records have been adopted globally. In Sweden, the current regulatory framework restricts ORA for minors and their guardians when the minor is aged between 13 and 15 years. Families of adolescents with complex health care needs often desire health information to manage their child's care and involve them in their care.
