New parenthood in ordinary times can be a vulnerable and unpredictable time. The Covid-19 pandemic brought additional, unprecedented changes to policy and practice that drastically impacted on the experiences of parents. This study aimed to enhance our understanding of the experiences of new parents during the pandemic by qualitatively analysing their experiences.

Results from selective deuteration and simulations have previously suggested that the role of protons in the biradical molecule depends on the strength of the electron-electron coupling. Here we use the cross effect DNP mechanism to identify and acquire H solid-state NMR spectra of the protons that contribute to propagation of the hyperpolarization, via an experimental approach dubbed Nuclear-Nuclear Double Resonance (NUDOR).

However, obtaining high-resolution structural information on native bacterial biofilms has remained elusive due to the methodological limitations associated with analyzing complex biological samples. Solid-state NMR (ssNMR) has shown promise in this regard, but its conventional application is hindered by sensitivity constraints for unlabeled samples.

Nuchal translucency (NT) increases with gestation and with genetic or structural abnormalities. This study aims to determine the utility of NT measurement in detecting genetic abnormalities not identified by gwNIPT and the optimal NT threshold value.

CK can be used as an investigation to support the diagnosis of conditions such as neuroleptic malignant syndrome (NMS), a rare idiosyncratic drug reaction - classically to antipsychotic medications - which can be fatal. Routine screening of CK in psychiatric inpatients is a known practice, but its value is uncertain.

Approximately 17% of active duty service members are female, and they face unique challenges in achieving timely recovery from concussions. Understanding the unique characteristics affecting return to unrestricted activity (RTA) among female service academy members is imperative for the ever-growing proportion of females across the U.

This review aims to identify the different explanations proposed for sustained higher-than-expected mortality beyond the first pandemic year.
Study Design: Scoping review.
Background & Aims: This American Gastroenterological Association (AGA) living guideline is intended to support practitioners in the pharmacological management of moderate-to-severe ulcerative colitis (UC).
Methods: A multidisciplinary panel of content experts and guideline methodologists used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework to prioritize clinical questions, identify patient-centered outcomes, conduct an evidence synthesis, and develop recommendations on the pharmacological management of moderate-to-severe UC.
Results: The AGA guideline panel made 14 recommendations.
Invasive aspergillosis poses a significant threat to immunocompromised patients, leading to high mortality rates associated with these infections. Targeting the biosynthesis of cell wall carbohydrates is a promising strategy for antifungal drug development and will be advanced by a molecular-level understanding of the native structures of polysaccharides within their cellular context. Solid-state NMR spectroscopy has recently provided detailed insights into the cell wall organization of Aspergillus fumigatus, but genetic and biochemical evidence highlights species-specific differences among Aspergillus species.

Methods: We searched multiple electronic databases through November 21, 2023, to identify randomized controlled trials in adults with moderate-to-severe UC, comparing different advanced therapies (tumor necrosis factor antagonists, vedolizumab, sphingosine-1-phosphate receptor modulators, interleukin 12/23 or selective interleukin 23 antagonists, and Janus kinase [JAK] inhibitors) against placebo or another active comparator. Our primary outcomes were induction and maintenance of clinical remission, and our secondary outcome was endoscopic improvement.
Bacterial biofilms cause persistent infections that are difficult to treat and contribute greatly to antimicrobial resistance. However, high-resolution structural information on native bacterial biofilms remain very limited. This limitation is primarily due to methodological constraints associated with analyzing complex native samples.

The Larval Packet Test (LPT) is the standard laboratory bioassay for resistance diagnosis, which requires triplicates of seven acaricidal dilutions plus controls to cover larval mortalities ranging between 0 and 100%. The value of the LPT lies in providing resistance ratios based on the ratio between the LC50 calculated with potentially resistant and susceptible ticks.
