Molecular features of the serological IgG repertoire elicited by egg-based, cell-based, or recombinant haemagglutinin-based seasonal influenza vaccines: a comparative, prospective, observational cohort study.

Background: Egg-based inactivated quadrivalent seasonal influenza vaccine (eIIV4), cell culture-based inactivated quadrivalent seasonal influenza vaccine (ccIIV4), and recombinant haemagglutinin (HA)-based quadrivalent seasonal influenza vaccine (RIV4) have been licensed for use in the USA. In this study, we used antigen-specific serum proteomics analysis to assess how the molecular composition and qualities of the serological antibody repertoires differ after seasonal influenza immunisation by each of the three vaccines and how different vaccination platforms affect the HA binding affinity and breadth of the serum antibodies that comprise the polyclonal response.

Methods: In this comparative, prospective, observational cohort study, we included female US health-care personnel (mean age 47·6 years [SD 8]) who received a single dose of RIV4, eIIV4, or ccIIV4 during the 2018-19 influenza season at Baylor Scott & White Health (Temple, TX, USA).

Mechanisms of life cycle simplification in African trypanosomes.

African trypanosomes are important parasites in sub-Saharan Africa that undergo a quorum-sensing dependent development to morphologically 'stumpy forms' in mammalian hosts to favour transmission by tsetse flies. However, some trypanosome clades have simplified their lifecycle by escaping dependence on tsetse allowing an expanded geographic range, with direct transmission between hosts achieved via blood-feeding biting flies and vampire bats (Trypanosoma brucei evansi, causing 'surra') or through sexual transmission (Trypanosoma brucei equiperdum, causing 'dourine'). Concomitantly, stumpy formation is reduced and the isolates are described as monomorphic, with infections spread widely in Africa, Asia, South America and parts of Europe.

Mediation of risk factors for high blood pressure in four racial and ethnic populations.

This study evaluated the extent to which body mass index (BMI) mediates associations between risk factors and incident high blood pressure in American Indians and Alaska Natives (AI/ANs), Non-Hispanic Whites (NHWs), Non-Hispanic Blacks (NHBs) and Hispanics. There were 7,793 participants from the National Longitudinal Study of Adolescent to Adult Health: 312 AI/ANs, 1,091 Hispanics, 1,567 NHBs and 4,823 NHWs. Risk factors for high blood pressure included adolescent BMI, TV watching, fast-food consumption, smoking, parental obesity, parental educational attainment and financial instability.

Age- and Parkinson-related differences in trunk and lower-limb muscle activation during four balance tasks: A case-control pilot study.

Background: Poor postural control has been reported in people with Parkinson's disease, which could be explained by the changes in muscular activation patterns related to antigravitational muscles. This study aims to measure the muscle activation of antigravitational muscles during balance tasks in individuals, with and without Parkinson's.

Methods: Sixteen (16) participants (9 with Parkinson's), aged ≥65 yrs.

Graphormer-IR: Graph Transformers Predict Experimental IR Spectra Using Highly Specialized Attention.

Infrared (IR) spectroscopy is an important analytical tool in various chemical and forensic domains and a great deal of effort has gone into developing methods for predicting experimental spectra. A key challenge in this regard is generating highly accurate spectra quickly to enable real-time feedback between computation and experiment. Here, we employ Graphormer, a graph neural network (GNN) transformer, to predict IR spectra using only simplified molecular-input line-entry system (SMILES) strings.

Resistance training in women with myotonic dystrophy type 1: a multisystemic therapeutic avenue.

Myotonic dystrophy type 1 (DM1) is a hereditary disease characterized by muscular impairments. Fundamental and clinical positive effects of strength training have been reported in men with DM1, but its impact on women remains unknown. We evaluated the effects of a 12-week supervised strength training on physical and neuropsychiatric health.

Physical impairments, activity limitations, and participation restrictions of childhood acute lymphoblastic leukemia survivors with and without hip osteonecrosis: a PETALE cohort study.

Purpose: Long-term musculoskeletal complications represent a growing burden for survivors of childhood acute lymphoblastic leukemia (cALL). This study aimed to describe physical impairments, activity limitations, and participation restrictions in a high-risk subgroup of cALL survivors of the PETALE cohort.

Methods: This cross-sectional study, using observational data from the PETALE cohort, included a subgroup of survivors who presented high-risk criteria for late effects.

Group Physical Therapy Programs for Military Members With Musculoskeletal Disorders: A Pragmatic Randomized Controlled Trial.

To compare the effects of personalized, supervised group-based programs (ie, group physical therapy programs) and usual one-on-one physical therapy care (ie, usual physical therapy care) on disability for military personnel suffering from low back pain, rotator cuff-related shoulder pain, patellofemoral pain syndrome, or lateral ankle sprain. Secondary outcomes were pain severity, pain-related fear, health-related quality of life, and patients' satisfaction with their condition and care. Non-inferiority pragmatic randomized clinical trial.

Conditioned pain modulation, kinesiophobia, and pain catastrophizing as prognostic factors for chronicity in a population with acute low back pain: An exploratory prospective study.

Background: Psychosocial factors and alteration of the somatosensory functions have been associated with persistent low back pain (LBP). A decreased capacity of the central nervous system to modulate pain has been suggested as a potential contributor to the persistence of pain.

Objective: To investigate whether conditioned pain modulation (CPM), initial symptoms/disability, kinesiophobia, and pain catastrophizing is associated with the transition from acute to chronic LBP.

Prevalence and seasonal dynamic of gastrointestinal parasites in equids in France during two years.

Grazing equids are constantly exposed to three clinically important gastrointestinal parasites (small strongyles/cyathostomins, Anoplocephala spp. and Parascaris spp.).

Toward a Better Understanding of Walking Speed in Ataxia of Charlevoix-Saguenay: a Factor Exploratory Study.

Mobility limitations, including a decrease in walking speed, are major issues for people with autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS). Improving our understanding of factors influencing walking speed in ARSACS may inform the development of future interventions for gait rehabilitation and contribute to better clinical practices. The objective of the study was to identify the factors influencing the self-selected walking speed in adults with ARSACS.

A proposal for a universal physical therapy diagnostic concept.

Background: In Canada, as in other countries, the physical therapist (PT) must make a diagnosis to comply with direct access responsibilities. This means making a diagnosis is an entry-to-practice essential competency. However, there is no consensus across physical therapy practice domains and contexts regarding the diagnostic concept, i.

European Inter-Laboratory Proficiency Test for Dourine Antibody Detection Using the Complement Fixation Test.

Dourine is a sexually transmitted parasitic disease affecting equids. Its causative agent is referred to as and the prescribed serodiagnosis method is the complement fixation test (CFT). In the context of our European Reference Laboratory mandate for equine diseases (excluding African horse sickness), we organised dourine CFT inter-laboratory proficiency tests (ILPTs) in 2015, 2018 and 2022 to evaluate the performance of the European Union network of National Reference Laboratories (NRLs) for dourine.

Integration of primary contact physiotherapists in the emergency department for individuals presenting with minor musculoskeletal disorders: Protocol for an economic evaluation.

Objectives: 1) To compare the average cost of an emergency department (ED) visit for various minor musculoskeletal disorders between two models of care (physiotherapist and ED physician or ED physician alone); 2) To evaluate the incremental cost-effectiveness ratio (ICER) of these two models of care over a 3-month period post-initial visit; and 3) To estimate the ICER of three ED models of care (physiotherapist and ED physician, ED physician alone, physiotherapist alone) over a two-year period.

Methods: Obj.1: The costs incurred by participants in the two groups during their ED visit will be calculated using the Time-Driven Activity-Based Costing (TDABC) method.

Prenatal Alcohol Counseling Among American Indian and Alaska Native Women and Non-Hispanic White Women in the Pregnancy Risk Assessment Monitoring System.

Objective: Universal screening and counseling are recommended for alcohol use during pregnancy, but no prior study has examined differences in prenatal counseling by race or ethnicity. We used Pregnancy Risk Assessment Monitoring System (PRAMS) data to assess differences in provision of counseling on prenatal alcohol use between American Indian/Alaska Native (AI/AN) and non-Hispanic White (NHW) women during prenatal care.

Methods: We analyzed data from 2014-2015 from the four PRAMS states with the highest number of births to AI/AN women: Alaska, New Mexico, Oklahoma, and Washington.

Measuring upper limb active joint position sense: Introducing a new clinical tool - The Upper Limb Proprioception Reaching Test.

Background: Proprioception is our sense of body awareness, including the sub-category of active joint position sense (AJPS). AJPS is fundamental to joint stability and movement coordination. Despite its importance, there remain few confident ways to measure upper limb AJPS in a clinic.

Relationship between food insecurity and a gestational diabetes risk reduction intervention: outcomes among American Indian and Alaska Native adolescent and young adult females.

American Indian and Alaska Natives (AI/ANs) are disproportionately impacted by gestational diabetes mellitus (GDM), subsequent type 2 diabetes, and food insecurity. It is prudent to decrease risk of GDM prior to pregnancy to decrease the intergenerational cycle of diabetes in AI/AN communities. The purpose of this project is to describe and examine food insecurity, healthy eating self-efficacy, and healthy eating behaviors among AI/AN females (12-24 years old) as related to GDM risk reduction.

"It Becomes a Family I'm a Part of…We Get to Carry Each Other": Themes from Qualitative Interview of Patients Enrolled in an Inpatient Palliative Care Support Program for Adolescents and Young Adults.
