Lipoproteins and lipoprotein lipid composition are associated with stages of dysglycemia and subclinical coronary atherosclerosis.

Background: Dyslipidaemia in patients with diabetes contributes to the risk of atherosclerotic cardiovascular disease. We aimed to identify a dyslipidemic profile associated with both dysglycemia and subclinical coronary atherosclerosis.

Methods: Study participants (n = 5050) were classified in three groups: normoglycemia, pre-diabetes, and diabetes.

Global Transcriptomic Analysis of Topical Sodium Alginate Protection against Peptic Damage in an In Vitro Model of Treatment-Resistant Gastroesophageal Reflux Disease.

Breakthrough symptoms are thought to occur in roughly half of all gastroesophageal reflux disease (GERD) patients despite maximal acid suppression (proton pump inhibitor, PPI) therapy. Topical alginates have recently been shown to enhance mucosal defense against acid-pepsin insult during GERD. We aimed to examine potential alginate protection of transcriptomic changes in a cell culture model of PPI-recalcitrant GERD.

Re-living trauma near death: an integrative review using Grounded Theory narrative analysis.

Background: Symptoms of emotional and physical stress near death may be related to previous experiences of trauma.

Objective: To investigate current evidence regarding the following: (1) Is previous trauma identified in people who are dying, and if so, how? (2) How is previous trauma associated with the experience of death/dying in people with or without cognitive impairment? and (3) What palliative care interventions are available to people with previous trauma at the end of life?

Design: This integrative review was conducted per Whittemore and Knafl's guidelines, which involves a stepped approach, specifically (1) problem identification, (2) literature search, (3) data evaluation, (4) data analysis and (5) presentation.

Methods: This integrative review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines.

Fish and shellfish allergy: Presentation and management differences in the UK and US-analysis of 945 patients.

Background: Seafood allergy (SA), including allergy to shellfish (crustacean and mollusks) and fish, is among the 4 most common food allergies causing anaphylaxis, but there are limited data showing SA clinical management in different countries.

Objective: We sought to characterize a large cohort of patients with fish and shellfish allergy and to facilitate standardization of future care for this increasingly common allergic disease.

Methods: We performed a retrospective, observational, noninterventional study from 945 patients from 2015 to 2019 in 7 hospitals in the United States and the United Kingdom to evaluate SA.

[Spontaneous coronary artery dissection and physical activity - what we know and don't know].

Patients suffering from a spontaneous coronary artery dissection (SCAD) are mostly younger to middle-aged women. There are very few data to guide physicians and physiotherapists on recommendations about physical activity for these patients. Based on the few studies that are available, aerobic activity at moderate levels and weightlifting with light weights appears safe.

manipulates , MEAM1 both directly and indirectly through changes in visual and volatile cues.

The sweetpotato whitefly, MEAM1, is one of the most devastating pests of row-crop vegetables worldwide, damaging crops directly through feeding and indirectly through the transmission of many different viruses, including the geminivirus Tomato yellow leaf curl virus (TYLCV). Y-tube olfactometer tests were conducted at different stages of TYLCV infection in tomatoes to understand how TYLCV affects behavior. We also recorded changes in tomato hosts' color and volatile profiles using color spectrophotometry and gas chromatography-mass spectrometry (GC-MS).

Sex-specific aspects on prognosis after aortic valve replacement for aortic stenosis: a SWEDEHEART registry study.

Objective: To compare long-term cardiovascular (CV) outcomes between men and women with aortic stenosis (AS) undergoing aortic valve replacement (AVR) by the type of valve implant.

Methods: The study population consisted of 14 123 non-selected patients with AS undergoing first-time AVR and included in the Swedish Web system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies (SWEDEHEART) registry during 2008-2016. Comparisons were made between men and women and type of valve implant (ie, surgical implantation with a mechanical (mSAVR) (n=1 966) or biological valve (bioSAVR) (n=9 801)) or by a transcatheter approach (TAVR) (n=2 356).

Social determinants of health and sepsis: a case-control study.

Purpose: We aimed to identify whether social determinants of health (SDoH) are associated with the development of sepsis and assess the differences between individuals living within systematically disadvantaged neighbourhoods compared with those living outside these neighbourhoods.

Methods: We conducted a single-centre case-control study including 300 randomly selected adult patients (100 patients with sepsis and 200 patients without sepsis) admitted to the emergency department of a large academic tertiary care hospital in Hamilton, ON, Canada. We collected data on demographics and a limited set of SDoH variables, including neighbourhood household income, smoking history, social support, and history of alcohol disorder.

Fluorescence Microscopy with Deep UV, Near UV, and Visible Excitation for Detection of Microorganisms.

We report a simple, inexpensive design of a fluorescence microscope with light-emitting diode (LED) excitation for detection of labeled and unlabeled microorganisms in mineral substrates. The use of deep UV (DUV) excitation with visible emission requires no specialized optics or slides and can be implemented easily and inexpensively using an oblique illumination geometry. DUV excitation (<280 nm) is preferable to near UV (365 nm) for avoidance of mineral autofluorescence.

Combining Cell-Intrinsic and -Extrinsic Resistance to HIV-1 By Engineering Hematopoietic Stem Cells for CCR5 Knockout and B Cell Secretion of Therapeutic Antibodies.

Autologous transplantation of null hematopoietic stem and progenitor cells (HSPCs) is the only known cure for HIV-1 infection. However, this treatment is limited because of the rarity of -null matched donors, the morbidities associated with allogeneic transplantation, and the prevalence of HIV-1 strains resistant to CCR5 knockout (KO) alone. Here, we propose a one-time therapy through autologous transplantation of HSPCs genetically engineered to produce both CCR5 KO cells and long-term secretion of potent HIV-1 inhibiting antibodies from B cell progeny.

Detectability of unresolved particles in off-axis digital holographic microscopy.

Off-axis digital holographic microscopy (DHM) provides both amplitude and phase images, and so it may be used for label-free 3D tracking of micro- and nano-sized particles of different compositions, including biological cells, strongly absorbing particles, and strongly scattering particles. Contrast is provided by differences in either the real or imaginary parts of the refractive index (phase contrast and absorption) and/or by scattering. While numerous studies have focused on phase contrast and improving resolution in DHM, particularly axial resolution, absent have been studies quantifying the limits of detection for unresolved particles.

17β-estradiol Attenuates the Middle Ear Inflammatory Response to Nontypeable Haemophilus influenzae.

Objectives: 17β-estradiol (E2) is a steroidal hormone with immunomodulatory functions that play a role in infectious and inflammatory diseases. E2 was recently identified as the leading upstream regulator of differentially expressed genes in a comparative RNA sequencing study of pediatric patients with otitis media (OM) versus OM-free counterparts and may therefore play a role in the inflammatory response to bacterial otopathogens during pediatric OM. This study examined the effect of E2 on bacterial-induced inflammatory cytokine expression in an in vitro pediatric OM model.

Twenty-six participants completed a pre-session survey. On average, they were 21 months post-COVID-19 infection (SD 10.

Inhaled fosamprenavir for laryngopharyngeal reflux: Toxicology and fluid dynamics modeling.

Objectives: Approximately 25% of Americans suffer from laryngopharyngeal reflux (LPR), a disease for which no effective medical therapy exists. Pepsin is a predominant source of damage during LPR and a key therapeutic target. Fosamprenavir (FOS) inhibits pepsin and prevents damage in an LPR mouse model.

Habituation of the cold shock response: A systematic review and meta-analysis.

Cold water immersion (CWI) evokes the life-threatening reflex cold shock response (CSR), inducing hyperventilation, increasing cardiac arrhythmias, and increasing drowning risk by impairing safety behaviour. Repeated CWI induces CSR habituation (i.e.

Biliary drainage in hilar and perihilar cholangiocarcinoma: 25-year experience at a tertiary cancer center.

Background And Aims: This study analyzed the optimal biliary stenting strategy for palliation in cholangiocarcinoma (CCA).

Methods: This was a retrospective study of patients with CCA who underwent biliary drainage from 1997 to 2023. A per-patient analysis of percutaneous transhepatic biliary drainage (PTBD) rates, the median number of ERCPs, and overall survival (OS) and a per-procedure analysis of clinical success (CS), stent-specific adverse events (AEs), and mean time to repeat ERCP by stent type and laterality (unilateral and bilateral) are presented.

Understanding the influence of medical education on physician geographic disposition: A qualitative study of family physician perspectives in Canada.

Rationale: Primary care access challenges are experienced by many communities. In several jurisdictions, including Canada, family physicians (FP) have the professional autonomy to organize their practice in alignment with professional and personal interests. Although system-level interventions are tremendously important, investment in upstream interventions associated with the medical education of graduating FPs is a promising strategy for ameliorating primary healthcare access challenges.

Establishment of novel immortalized middle ear cell lines as models for otitis media.

Objective: Otitis media (OM) is among the most frequently diagnosed pediatric diseases in the US. Despite the significant public health burden of OM and the contribution research in culture models has made to understanding its pathobiology, a singular immortalized human middle ear epithelial (MEE) cell line exists (HMEEC-1, adult-derived). We previously developed MEE cultures from pediatric patients with non-inflamed MEE (PCI), recurrent OM (ROM), or OM with effusion (OME) and demonstrated differences in their baseline inflammatory cytokine expression and response to stimulation with an OM-relevant pathogen lysate and cytokines.

Half a century after their discovery: Structural insights into exonuclease and annealase proteins catalyzing recombineering.

Recombineering is an essential tool for molecular biologists, allowing for the facile and efficient manipulation of bacterial genomes directly in cells without the need for costly and laborious manipulations involving restriction enzymes. The main workhorses behind recombineering are bacteriophage proteins that promote the single-strand annealing (SSA) homologous recombination pathway to repair double-stranded DNA breaks. While there have been several reviews examining recombineering methods and applications, comparatively few have focused on the mechanisms of the proteins that are the key players in the SSA pathway: a 5'→3' exonuclease and a single-strand annealing protein (SSAP or "annealase").
