Asthma.

Asthma is one of the most common chronic non-communicable diseases worldwide and is characterised by variable airflow obstruction, causing dyspnoea and wheezing. Highly effective therapies are available; asthma morbidity and mortality have vastly improved in the past 15 years, and most patients can attain good asthma control. However, undertreatment is still common, and improving patient and health-care provider understanding of when and how to adjust treatment is crucial.

The Rationality of Implementation of Dimethyl Sulfoxide as Differentiation-inducing Agent in Cancer Therapy.

One of the major hallmarks of many cancer cells is dedifferentiated cells (immature cells) with little or no resemblance to normal cells. Besides the poor differentiation, malignant cells also have important features such as aggressiveness and resistance to different therapeutics. Differentiation potentiators hold great promise for cancer treatment.

GATA4 controls regionalization of tissue immunity and commensal-driven immunopathology.

There is growing recognition that regionalization of bacterial colonization and immunity along the intestinal tract has an important role in health and disease. Yet, the mechanisms underlying intestinal regionalization and its dysregulation in disease are not well understood. This study found that regional epithelial expression of the transcription factor GATA4 controls bacterial colonization and inflammatory tissue immunity in the proximal small intestine by regulating retinol metabolism and luminal IgA.

A smarter perspective: Learning with and from AI-cases.

Artificial intelligence (AI) has only partially (or not at all) been integrated into medical education, leading to growing concerns regarding how to train healthcare practitioners to handle the changes brought about by the introduction of AI. Programming lessons and other technical information into healthcare curricula has been proposed as a solution to support healthcare personnel in using AI or other future technology. However, integrating these core elements of computer science knowledge might not meet the observed need that students will benefit from gaining practical experience with AI in the direct application area.

Aortic arch surgery for type B aortic dissection: How far should we go? The value of a hybrid approach.

Traditionally, the management of type B aortic dissection has been the domain of the vascular surgeons. Timing and type of intervention still generate debate. We sought to review our early experience with the treatment of this condition based on a hybrid approach following an aortic multi-disciplinary team meeting involving close cooperation between cardiac surgeons, vascular surgeons, interventional radiologists, vascular anesthetists, and cardiac anesthetists.

A scoping review on the impact of austerity on healthcare access in the European Union: rethinking austerity for the most vulnerable.

The Potential of Children's Rearing Environment to Overcome Genetic Propensity for Low Reading Achievement.

Genetic studies show that children's reading achievement is in part genetically influenced, and intervention studies show that reading achievement can be increased by environmental interventions. However, correlational and mean-level analytic strategies are rarely integrated into achievement research, potentially leading to misinterpretation of results. The parent-offspring adoption design offers a novel opportunity to examine the independent and joint roles of genetic and rearing environmental contributions.

Disrupting Maternal Transmission of Depression: Using Integrative Data Analysis (IDA) to Examine Indirect Effects of the Family Check-Up (FCU) Across Three Randomized Trials.

Maternal depression is a well-established risk factor for the development of depression in offspring. As such, reducing maternal depression may be key to effective prevention efforts to reduce offspring's depression. Based on the broad risk represented by maternal depression, examining cross-over effects of parent-focused interventions on maternal depression is important.

Association of Developmental Language Disorder With Comorbid Developmental Conditions Using Algorithmic Phenotyping.

Importance: Developmental language disorder (DLD) is a common (with up to 7% prevalence) yet underdiagnosed childhood disorder whose underlying biological profile and comorbidities are not fully understood, especially at the population level.

Objective: To identify clinically relevant conditions that co-occur with DLD at the population level.

Design, Setting, And Participants: This case-control study used an electronic health record (EHR)-based population-level approach to compare the prevalence of comorbid health phenotypes between DLD cases and matched controls.

Mosaic Recombination Inflicted Various SARS-CoV-2 Lineages to Emerge into Novel Virus Variants: a Review Update.

Human Coronaviruses (hCoVs) belongs to the enormous and dissimilar family of positive-sense, non-segmented, single-stranded RNA viruses. The RNA viruses are prone to high rates of mutational recombination resulting in emergence of evolutionary variant to alter various features including transmissibility and severity. The evolutionary changes affect the immune escape and reduce effectiveness of diagnostic and therapeutic measures by becoming undetectable by the currently available diagnostics and refractory to therapeutics and vaccines.

Procalcitonin Evaluation of Antibiotic Use in COVID-19 Hospitalised Patients (PEACH): Protocol for a Retrospective Observational Study.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel virus responsible for the coronavirus disease 2019 (COVID-19) pandemic. Although COVID-19 is a viral illness, many patients admitted to hospital are prescribed antibiotics, based on concerns that COVID-19 patients may experience secondary bacterial infections, and the assumption that they may respond well to antibiotic therapy. This has led to an increase in antibiotic use for some hospitalised patients at a time when accumulating antibiotic resistance is a major global threat to health.

COVID-19 Vaccination: Does It Alter Postoperative Mortality and Morbidity in Hip Fractures?

Introduction The primary aim of our study was to evaluate the impact of coronavirus disease 2019 (COVID-19) vaccination on mortality in patients with hip fractures by comparing it to those who are unvaccinated. Our secondary objective was to compare the impact on postoperative morbidity parameters like length of hospital stay and complications. Methods A total of 619 hip fractures were divided into the 'Vaccinated group' consisting of 300 patients who had COVID-19 vaccination and the 'Unvaccinated group' consisting of 319 patients who were not vaccinated.

Risk Factors of 120-Day Mortality Among Hip Fractures With Concomitant COVID-19 Infection.

Background Hip fractures cause substantial morbidity and mortality worldwide, and the coronavirus disease 2019 (COVID-19) pandemic has only worsened the global burden. Increased 120-day mortality is well established in the literature among hip fractures with COVID-19. However, the risk factors associated with mortality have been poorly understood.

Gating and modulation of an inward-rectifier potassium channel.

Inward-rectifier potassium channels (Kirs) are lipid-gated ion channels that differ from other K+ channels in that they allow K+ ions to flow more easily into, rather than out of, the cell. Inward rectification is known to result from endogenous magnesium ions or polyamines (e.g.

Safety of Periprocedural Antithrombotics during Pediatric Transplant Liver Biopsies.

The purpose of this study was to compare the adverse event (AE) rates of percutaneous pediatric transplant liver biopsies in patients receiving periprocedural antithrombotic agents with those in patients not receiving them. A 19-year retrospective single-center study of ultrasound-guided transplant liver biopsies was conducted. Patients who received aspirin for <5 days (n = 51) or heparin <4 hours (n = 15) before biopsy were separately grouped.

Imaging of pediatric brain tumors: A COG Diagnostic Imaging Committee/SPR Oncology Committee/ASPNR White Paper.

Tumors of the central nervous system are the most common solid malignancies in children and the most common cause of pediatric cancer-related mortality. Imaging plays a central role in diagnosis, staging, treatment planning, and response assessment of pediatric brain tumors. However, the substantial variability in brain tumor imaging protocols across institutions leads to variability in patient risk stratification and treatment decisions, and complicates comparisons of clinical trial results.

Metasurface-enhanced mid-infrared spectroscopy in the liquid phase.

Vibrational spectroscopy is an important tool in chemical and biological analysis. A key issue when applying vibrational spectroscopy to dilute liquid samples is the inherently low sensitivity caused by short interaction lengths and small extinction coefficients, combined with low target molecule concentrations. Here, we introduce a novel type of surface-enhanced infrared absorption spectroscopy based on the resonance of a dielectric metasurface.
