Management of Labral Tears in the Hip: A Consensus Statement.

Background: Inconsistencies in the workup of labral tears in the hip have been shown to result in a delay in treatment and an increased cost to the medical system.

Purpose: To establish consensus statements among Canadian nonoperative/operative sports medicine physicians via a modified Delphi process on the diagnosis, nonoperative and operative management, and rehabilitation and return to play (RTP) of those with labral tears in the hip.

Study Design: A consensus statement.

Food access and the severity of newly diagnosed pediatric inflammatory bowel disease.

Objectives: Inflammatory bowel disease (IBD) results from genetic susceptibility, gut microbiome, and environmental factors. Diet, one modifiable environmental factor, has been linked to the increased prevalence of IBD. This study aimed to evaluate a potential association between food deserts and disease severity at diagnosis.

Seatizen Atlas: a collaborative dataset of underwater and aerial marine imagery.

Citizen Science initiatives have a worldwide impact on environmental research by providing data at a global scale and high resolution. Mapping marine biodiversity remains a key challenge to which citizen initiatives can contribute. Here we describe a dataset made of both underwater and aerial imagery collected in shallow tropical coastal areas by using various low cost platforms operated either by citizens or researchers.

The objective was to determine whether incorporating the Human Factors Analysis and Classification System could lead to a perceived increase in the overall quality of morbidity and mortality presentations through the standardization of classifying cause factors of medical errors.

Methods: This study involved eight emergency medicine residents who applied the adapted Human Factors Analysis and Classification System framework to their morbidity and mortality case presentations over 6 months.

H3.1K27M-induced misregulation of the TSK/TONSL-H3.1 pathway causes genomic instability.

The oncomutation lysine 27-to-methionine in histone H3 (H3K27M) is frequently identified in tumors of patients with diffuse midline glioma-H3K27 altered (DMG-H3K27a). H3K27M inhibits the deposition of the histone mark H3K27me3, which affects the maintenance of transcriptional programs and cell identity. Cells expressing H3K27M are also characterized by defects in genome integrity, but the mechanisms linking expression of the oncohistone to DNA damage remain mostly unknown.

Conservation of function without conservation of amino acid sequence in intrinsically disordered transcriptional activation domains.

Protein function is canonically believed to be more conserved than amino acid sequence, but this idea is only well supported in folded domains, where highly diverged sequences can fold into equivalent 3D structures. In contrast, intrinsically disordered protein regions (IDRs) do not fold into a stable 3D structure, thus it remains unknown when and how function is conserved for IDRs that experience rapid amino acid sequence divergence. As a model system for studying the evolution of IDRs, we examined transcriptional activation domains, the regions of transcription factors that bind to coactivator complexes.

The Nutritional Content of Food in Carceral Institutions: A Systematic Review of Quantitative Studies.

The nutritional content of food in carceral institutions is important because it influences weight gain and health during incarceration. This systematic review assessed the available quantitative data and nutritional analyses of food in carceral institutions. Methodology is based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement with four phases (identification, screening, eligibility, and inclusion).

Rat Model of Right-Sided Cardiac Remodeling and Arrhythmia using Pulmonary Artery Banding.

Clinical conditions, including chronic obstructive pulmonary disease or pulmonary arterial hypertension (PAH), can lead to chronic right ventricle pressure overload and progressive right heart failure (RHF). RHF can be identified by right-sided cardiac hypertrophy and dilation associated with abnormal myocardial function affecting the RV and the right atrium (RA). We recently demonstrated that severe RHF is accompanied by an increased risk of atrial inflammation, atrial fibrosis, and atrial fibrillation (AF), the most common type of cardiac arrhythmia (CA).

Subjective and objective sleep quality assessment in adolescent patients with inflammatory bowel disease.

Objectives: There is a link between inflammatory bowel disease (IBD) and poor sleep quality that is presumed to be multifactorial. The purpose of this study was to identify factors that impact sleep quality in this group including clinical disease activity, depression, anxiety, quality of life, and disordered social media use through questionnaires.

Methods: This prospective study analyzed sleep quality in adolescent patients ages 13 to 18 with a diagnosis of IBD using objective data from wrist actigraphy and subjective report from the Pittsburgh Sleep Quality Index (PSQI).

Greater TIMP-1 protein levels and neointimal formation represent sex-dependent cellular events limiting aortic vessel expansion in female rats.

Fragmentation/loss of the structural protein elastin represents the precipitating event translating to aortic expansion and subsequent aneurysm formation. The present study tested the hypothesis that greater protein expression of tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) and neointimal growth secondary to a reduction of medial elastin content represent sex-dependent events limiting aortic vessel expansion in females. TIMP-1 protein levels were higher in the ascending aorta of female versus male patients diagnosed with a bicuspid aortic valve (BAV).

Progress and future directions for seaweed holobiont research.

In the marine environment, seaweeds (i.e. marine macroalgae) provide a wide range of ecological services and economic benefits.

Plant and algal lipidomes: Analysis, composition, and their societal significance.

Plants and algae play a crucial role in the earth's ecosystems. Through photosynthesis they convert light energy into chemical energy, capture CO2 and produce oxygen and energy-rich organic compounds. Photosynthetic organisms are primary producers and synthesize the essential omega 3 and omega 6 fatty acids.

The role of neutral and adaptive evolutionary processes on patterns of genetic diversity across small cave-dwelling populations of Icelandic Arctic charr ().

Understanding the adaptability of small populations in the face of environmental change is a central problem in evolutionary biology. Solving this problem is challenging because neutral evolutionary processes that operate on historical and contemporary timescales can override the effects of selection in small populations. We assessed the effects of isolation by colonization (IBC), isolation by dispersal limitation (IBDL) as reflected by a pattern of isolation by distance (IBD), and isolation by adaptation (IBA) and the roles of genetic drift and gene flow on patterns of genetic differentiation among 19 cave-dwelling populations of Icelandic Arctic charr ().

Fine scale diversity in the lava: genetic and phenotypic diversity in small populations of Arctic charr Salvelinus alpinus.

Background: A major goal in evolutionary biology is to understand the processes underlying phenotypic variation in nature. Commonly, studies have focused on large interconnected populations or populations found along strong environmental gradients. However, studies on small fragmented populations can give strong insight into evolutionary processes in relation to discrete ecological factors.

Mixed methods to evaluate knowledge, attitudes and practices (KAP) towards rabies in central and remote communities of Moramanga district, Madagascar.

Control of dog-mediated rabies relies on raising awareness, access to post-exposure prophylaxis (PEP) and mass dog vaccination. To assess rabies awareness in Moramanga district, Madagascar, where rabies is endemic, two complementary quantitative and qualitative approaches were carried out in 2018. In the quantitative approach, a standardized questionnaire was administered to 334 randomized participants living in 170 households located less than 5 km from the anti-rabies treatment center (ARTC) located in Moramanga city (thereafter called the central area), and in 164 households located more than 15 km away from the ARTC in two rural communes (thereafter called the remote area).

Atrial cardiomyocytes contribute to the inflammatory status associated with atrial fibrillation in right heart disease.

Aims: Right heart disease (RHD), characterized by right ventricular (RV) and atrial (RA) hypertrophy, and cardiomyocytes' (CM) dysfunctions have been described to be associated with the incidence of atrial fibrillation (AF). Right heart disease and AF have in common, an inflammatory status, but the mechanisms relating RHD, inflammation, and AF remain unclear. We hypothesized that right heart disease generates electrophysiological and morphological remodelling affecting the CM, leading to atrial inflammation and increased AF susceptibility.

Importance of quorum sensing crosstalk in the brown alga epimicrobiome.

Brown macroalgae are colonized by diverse microorganisms influencing the physiology of their host. However, cell-cell interactions within the surface microbiome (epimicrobiome) are largely unexplored, despite the significance of specific chemical mediators in maintaining host-microbiome homeostasis. In this study, by combining liquid chromatography coupled to mass spectrometry (LC-MS) analysis and bioassays, we demonstrated that the widely diverse fungal epimicrobiota of the brown alga can affect quorum sensing (QS), a type of cell-cell interaction, as well as bacterial biofilm formation.

Empirical evidence for metabolic drift in plant and algal lipid biosynthesis pathways.

Metabolic pathway drift has been formulated as a general principle to help in the interpretation of comparative analyses between biosynthesis pathways. Indeed, such analyses often indicate substantial differences, even in widespread pathways that are sometimes believed to be conserved. Here, our purpose is to check how much this interpretation fits to empirical data gathered in the field of plant and algal biosynthesis pathways.
