Synthesis of expert opinions on fluid management in severe sepsis: A contextual review of human albumin and crystalloids.

Background: Sepsis is a critical condition associated with high mortality rates that necessitates effective fluid resuscitation. Crystalloids are widely utilized; however, human albumin solutions have been attributed potential oncotic and anti-inflammatory benefits. Given the ongoing debate and the absence of definitive empirical evidence, expert opinions provide valuable insights into the contextual and practical aspects of fluid management.

AP39, a novel mitochondria-targeted hydrogen sulfide donor, promotes cutaneous wound healing in an in vivo murine model of acute frostbite injury.

Frostbite injury refers to cold tissue injury which typically affects the peripheral areas of the body, and is associated with limb loss and high rates of morbidity. Historically, treatment options have been limited to supportive care, leading to suboptimal outcomes for affected patients. The pathophysiology of frostbite injury has been understood in recent years to share similarity with that of cold ischemia-reperfusion injury as seen in solid organ transplantation, of which mitochondria play an important contributing role.

Assessing the potential acoustic impact of floating offshore wind farms in the Central Mediterranean Sea.

The Strait of Sicily, a vital marine passage with diverse fauna, is seeing a steep rise in the planning of offshore wind farm projects. This study assesses the acoustic impact of these wind farms on local marine species. Underwater propagation was modeled for three proposed floating wind farms using JASCO's Marine Operations Noise Model (MONM), which integrates a parabolic equation method for frequencies from 10 to 800 Hz and a beam-tracing model for 1 to 25 kHz.

Mimicking the reactivity of drug metabolites: Biomolecule conjugation of an electrochemically-generated, reactive oxidation product of the antibiotic minocycline.

Minocycline is an antibiotic of the tetracycline family which is widely used to treat a range of medical conditions. Although it has been in use for more than 50 years, little information is available on its metabolism in the human body. In this study, we simulate the biotransformation of minocycline by means of electrochemistry coupled to mass spectrometry.

Objective: To evaluate the amount and types of physical activity (PA) performed by Greek women during pregnancy and assess the validity and reliability of the Greek version of the Pregnancy Physical Activity Questionnaire (PPAQ).

Study Design: This prospective study comprised two stages. The first stage was the completion of the PPAQ Greek version twice, with a one-week interval between the two rounds, to assess internal consistency and reproductivity.

Safety and efficacy of tamoxifen in non-ambulant patients with Duchenne muscular dystrophy: a multicentre, randomised, double-blind, placebo-controlled, phase 3 trial (TAMDMD Group B).

Most patients with Duchenne muscular dystrophy (DMD) are non-ambulant. Preserving proximal motor function is crucial, rarely studied. Tamoxifen, a selective oestrogen receptor modulator, reduced signs of muscular pathology in a DMD mouse model.

What happens after menopause? (WHAM): A prospective controlled study of cognition 24 months after premenopausal risk-reducing salpingo-oophorectomy.

Objective: Women with BRCA1/2 pathogenic variants considering risk-reducing bilateral oophorectomy (RRSO) may be concerned about potential effects of surgical menopause on cognition. Whether RRSO affects cognition and whether hormone therapy (HT) modifies this effect remains uncertain. This study aimed to prospectively measure the effect of premenopausal RRSO on cognition and the modifying effects of HT up to 24 months.

The effect of bone relaxation on the simulated pull-off force of a cementless femoral knee implant.

Aseptic loosening is the primary cause of revision in cementless total knee arthroplasty (TKA), emphasizing the importance of strong initial stability for long-term implant success. Pre-clinical evaluations are crucial for understanding implant fixation mechanics and improving implant designs. Finite element (FE) analysis models often use linear elastic bone material models, which do not accurately reflect bone's mechanical behavior.

Plasma phosphorylated tau217 strongly associates with memory deficits in the Alzheimer's disease spectrum.

Plasma phosphorylated tau biomarkers open unprecedented opportunities for identifying carriers of Alzheimer's disease pathophysiology in early disease stages using minimally invasive techniques. Plasma p-tau biomarkers are believed to reflect tau phosphorylation and secretion. However, it remains unclear to what extent the magnitude of plasma p-tau abnormalities reflects neuronal network disturbance in the form of cognitive impairment.

Concepts of Suffering at the End of Life Amongst Emergency, Palliative Care and Geriatric Medicine Physicians in Malaysia.

Background: Palliative Care, Geriatrics and Emergency physicians are exposed to death, terminally ill patients and distress of patients and their families. As physicians bear witness to patients' suffering, they are vulnerable to the costs of caring-the emotional distress associated with providing compassionate and empathetic care to patients. If left unattended, this may culminate in burnout and compromise professional identity.

Oral Regimens for Rifampin-Resistant, Fluoroquinolone-Susceptible Tuberculosis.

Background: For decades, poor treatment options and low-quality evidence plagued care for patients with rifampin-resistant tuberculosis. The advent of new drugs to treat tuberculosis and enhanced funding now permit randomized, controlled trials of shortened-duration, all-oral treatments for rifampin-resistant tuberculosis.

Methods: We conducted a phase 3, multinational, open-label, randomized, controlled noninferiority trial to compare standard therapy for treatment of fluoroquinolone-susceptible, rifampin-resistant tuberculosis with five 9-month oral regimens that included various combinations of bedaquiline (B), delamanid (D), linezolid (L), levofloxacin (Lfx) or moxifloxacin (M), clofazimine (C), and pyrazinamide (Z).

Chromosome length genome assembly of the stone marten (Martes foina, Mustelidae): a new view on one of the cornerstones in carnivore cytogenetics.

The stone marten (Martes foina) is an important species for cytogenetic studies in the order Carnivora. ZooFISH probes created from its chromosomes provided a strong and clean signal in chromosome painting experiments and were valuable for studying the evolution of carnivoran genome architecture. The research revealed that the stone marten chromosome set is similar to the presumed ancestral karyotype of the Carnivora, which added an additional value for the species.

Early-life Exposure to Tobacco Smoke and the Risk of Idiopathic Pulmonary Fibrosis: A Population-based Cohort Study.

Rationale: Tobacco smoking is a well-established risk factor for idiopathic pulmonary fibrosis (IPF), yet the influence of early-life tobacco exposure on future IPF risk remains poorly understood.

Objectives: To test the hypothesis that early-life tobacco exposure may elevate the risk of developing IPF, with this effect potentially modified by genetic susceptibility to IPF and mediated through accelerated biological aging.

Methods: Using data from over 430,000 participants in the UK Biobank, we performed a prospective cohort study to examine the associations of maternal smoking around birth and age of smoking initiation with IPF risk.

[Clinical phenotype of abdominal obesity and dynapenia: Brazilian Longitudinal Study of Aging (ELSI-Brazil)].

This study aims to examine the prevalence of abdominal obesity-dynapenia phenotype, identified by the presence of abdominal obesity and dynapenia, and understand its associated factors with a representative sample of the Brazilian population. Data were collected from the baseline of the Brazilian Longitudinal Study of Aging (ELSI-Brasil) 2015-2016. Abdominal obesity was determined by a waist-to-height ratio ≥ 0.

Recalibrating Protection Factors Using Millisecond Hydrogen/Deuterium Exchange Mass Spectrometry.

Hydrogen/deuterium exchange mass spectrometry (HDX-MS) is a powerful technique to interrogate protein structure and dynamics. With the ability to study almost any protein without a size limit, including intrinsically disordered ones, HDX-MS has shown fast growing importance as a complement to structural elucidation techniques. Current experiments compare two or more related conditions (sequences, interaction partners, excipients, conformational states, etc.

Correcting a pathogenic mitochondrial DNA mutation by base editing in mice.

Primary mitochondrial disorders are most often caused by deleterious mutations in the mitochondrial DNA (mtDNA). Here, we used a mitochondrial DddA-derived cytosine base editor (DdCBE) to introduce a compensatory edit in a mouse model that carries the pathological mutation in the mitochondrial transfer RNA (tRNA) alanine (mt-tRNA) gene. Because the original m.

Tracing the inner edge of the habitable zone with sulfur chemistry.

The circumstellar liquid-water habitable zone guides our search for potentially inhabited exoplanets but remains observationally untested. We show that the inner edge of the habitable zone can now be mapped among exoplanets using their lack of surface water, which, unlike the presence of water, can be unambiguously revealed by atmospheric sulfur species. Using coupled climate-chemistry modeling, we find that the observability of sulfur gases on exoplanets depends critically on the ultraviolet (UV) flux of their host star, a property with wide variation: Most M-dwarfs have a low UV flux and thereby allow the detection of sulfur gases as a tracer of dry planetary surfaces; however, the UV flux of Trappist-1 may be too high for sulfur to disambiguate uninhabitable from habitable surfaces on any of its planets.
