Phage therapy is a therapeutic approach to treat multidrug-resistant (MDR) infections that employs lytic bacteriophages (phages) to eliminate bacteria. Despite the abundant evidence for its success as an antimicrobial in Eastern Europe, there is scarce data regarding its effects on the human host. Here, we aimed to understand how lytic phages interact with cells of the airway epithelium, the tissue site that is colonized by bacterial biofilms in numerous chronic respiratory disorders. Using a panel of Pseudomonas aeruginosa phages and human airway epithelial cells (AECs) derived from a person with cystic fibrosis (CF), we determined that interactions between phages and epithelial cells depend on specific phage properties as well as physiochemical features of the microenvironment...

Sleep is fundamental to health. The aim of this study was to analyse and determine factors predicting sleep quality during and after national lockdowns due to severe acute respiratory syndrome coronavirus 2 (COVID-19) in the UK. A longitudinal online survey-based study (SleepQuest) involving UK adults was administered in Spring 2020, Winter 2020, and Winter 2022 including questionnaires probing sleep quality, depression, anxiety, beliefs about sleep, demographics, COVID-19 status, and exercise. The primary outcome was sleep quality (Pittsburgh Sleep Quality Index)...

We report an experimental and computational investigation of the likely mechanism of a cascade reaction. The reaction involves an intramolecular Diels-Alder reaction, followed by a C-C bond cleavage, to afford a complex bridged bicyclic product. As multiple reaction pathways could be envisioned for the latter step, the mechanism of the C-C bond cleavage step was investigated. Two reasonable reaction pathways were evaluated. Both computations and experiments indicate that the C-C bond cleavage step proceeds by a retro-carbonyl-ene pathway rather than a retro-aldol pathway...

When used as pump pulses in transient absorption spectroscopy measurements, femtosecond laser pulses can produce oscillatory signals known as quantum beats. The quantum beats arise from coherent superpositions of the states of the sample and are best studied in the Fourier domain using Femtosecond Coherence Spectroscopy (FCS), which consists of one-dimensional amplitude and phase plots of a specified oscillation frequency as a function of the detection frequency. Prior works have shown ubiquitous amplitude nodes and π phase shifts in FCS from excited-state vibrational wavepackets in monomer samples...

Damage control surgery has evolved during the past 40 years. The initial cases and studies were performed at level 1 trauma centers but has now shifted to damage control at smaller hospitals. This buys time for definitive care at higher-level centers. There is a role for damage control surgery in both general surgery and trauma patients at community trauma centers. The successful implementation and completion of damage control surgery require thorough planning and a full understanding of resource limitation...

Acute calcific longus colli tendinitis is a differential diagnosis of neck pain. Typical presentation consists in a triad of symptoms including acute onset neck pain, neck stiffness and odynophagia. Computed tomography (CT) is the gold standard for acute calcific longus colli tendinitis diagnosis and the main radiological findings include prevertebral soft tissue swelling and the presence of amorphous calcifications. The case involves a 39-year-old female who presented to the emergency department with acute unilateral cervical pain that resulted in acute calcific longus colli tendinitis...

Alzheimer's disease (AD), the most common etiology of dementia in older adults, is projected to double in prevalence over the next few decades. Current treatments for AD manage symptoms or slow progressive decline, but are accompanied by significant inconvenience, risk, and cost. Thus, a better understanding of the risk factors and pathophysiology of AD is needed to develop novel prevention and treatment strategies. Aging is the most important risk factor for AD. Elucidating molecular mechanisms of aging may suggest novel therapeutic targets...

Dieting is theorized as a risk factor for loss-of-control (LOC)-eating (i.e., feeling a sense of lack of control while eating). Support for this association has largely relied on retrospective self-report data, which does not always correlate with objectively assessed eating behavior in youth. We hypothesized that during a laboratory-based LOC-eating paradigm, children and adolescents who reported current (at the time of the visit) dieting would consume meals consistent with LOC-eating (greater caloric intake, and intake of carbohydrates and fats, but less intake of protein)...

Network meta-analysis (NMA) usually provides estimates of the relative effects with the highest possible precision. However, sparse networks with few available studies and limited direct evidence can arise, threatening the robustness and reliability of NMA estimates. In these cases, the limited amount of available information can hamper the formal evaluation of the underlying NMA assumptions of transitivity and consistency. In addition, NMA estimates from sparse networks are expected to be imprecise and possibly biased as they rely on large-sample approximations that are invalid in the absence of sufficient data...
