Background: Mislabeled drug allergy can restrict future prescriptions and medication use, but its prevalence and impact among patients with stroke remain unknown. This study investigated the prevalence of the most commonly labeled drug allergies, their accuracy, and their impact among patients with stroke.

Methods: In this combined longitudinal and cross-sectional study, we compared the prevalence of allergy labels among the general population and patients with ischemic stroke between 2008 and 2014 from electronic health care records in Hong Kong.

Article Synopsis
  • The study investigates the differences in body composition, strength, and power between forwards and backs in English women's rugby union players, highlighting the impact of seasonal variations on these physical traits.
  • It involved testing 47 players at three different points during the 2020-2021 season, revealing that forwards typically had greater body mass and lean mass, while backs excelled in jump height and reactive strength.
  • The findings suggest that understanding these variations can help coaches tailor training programs effectively to enhance performance in both player positions throughout the season.

Purpose: We wanted to develop a deep-learning algorithm to automatically segment optic nerve head (ONH) and macula structures in three-dimensional (3D) wide-field optical coherence tomography (OCT) scans and to assess whether 3D ONH or macula structures (or a combination of both) provide the best diagnostic power for glaucoma.

Methods: A cross-sectional comparative study was performed using 319 OCT scans of glaucoma eyes and 298 scans of nonglaucoma eyes. Scans were compensated to improve deep-tissue visibility.

Article Synopsis
  • The rise in microbial genome sequences has led to resistance gene-guided genome mining, a method used to discover natural products with specific bioactivities.
  • Researchers identified roseopurpurins as strong inhibitors of cyclin-dependent kinases (CDKs), which are linked to various cancers, through this innovative approach.
  • Their work involved disrupting genes and expressing a biosynthetic gene cluster that confirmed roseopurpurin C's production, finding it effectively inhibits human CDK2 with a potency of 44 nM and leads to G1 cell cycle arrest in cancer cells.

Article Synopsis
  • CAR-T therapy is effective for B-cell lymphoma but is costly and has safety concerns due to its complicated genetic modification process.
  • A new approach, antibody-cell conjugation (ACC), allows for attaching cancer-targeting antibodies to immune cells without genetic changes, resulting in a treatment called ACE1831, which uses rituximab-conjugated γδ2 T cells.
  • ACE1831 showed enhanced cancer-killing ability in lab studies and improved survival in mice with B-cell lymphoma, showing promise as an accessible treatment option without harmful side effects.

Oncogenic KRAS mutations are a key driver for initiation and progression in non-small cell lung cancer (NSCLC). However, how post-translational modifications (PTMs) of KRAS, especially methylation, modify KRAS activity remain largely unclear. Here, we show that SET domain containing histone lysine methyltransferase 7 (SETD7) interacts with KRAS and methylates KRAS at lysines 182 and 184.

Conventionally, hyperimmune globulin drugs manufactured from pooled immunoglobulins from vaccinated or convalescent donors have been used in treating infections where no treatment is available. This is especially important where multi-epitope neutralization is required to prevent the development of immune-evading viral mutants that can emerge upon treatment with monoclonal antibodies. Using microfluidics, flow sorting, and a targeted integration cell line, a first-in-class recombinant hyperimmune globulin therapeutic against SARS-CoV-2 (GIGA-2050) was generated.

Background: Muscle wasting may explain the paradoxical mortality of patients with high estimated glomerular filtration rates (eGFRs) derived from equation methods. However, empirical evidence and solutions remain insufficient.

Methods: In this retrospective cohort study, we compared the performance of equation methods for predicting all-cause mortality; we used 24-h creatinine clearance (24-h CrCl), equation-based eGFRs, and a new eGFR estimating equation weighting for population 24-h urine creatinine excretion rate (U-CER).

In this study, biomimetic Mg-N -C from leaves were mixed with carbon black (L/C catalyst), in which the mixture was treated by a conventional microwave oven at 700 W and 2 min, exhibiting high catalytic activity for the oxygen reduction reaction (ORR). By using a microwave-assisted process, it not only offers a cheaper and faster way to synthesize the catalyst compared to the conventional furnace process but also avoids the decomposition of the N-structure. Using the optimized conditions, the L/C catalyst exhibits an electron transfer number of 3.

Background: Cohort studies in Bangladesh showed promising cure rates among patients with multidrug-resistant tuberculosis who received existing drugs in regimens shorter than that recommended by the World Health Organization (WHO) in 2011.

Methods: We conducted a phase 3 noninferiority trial in participants with rifampin-resistant tuberculosis that was susceptible to fluoroquinolones and aminoglycosides. Participants were randomly assigned, in a 2:1 ratio, to receive a short regimen (9 to 11 months) that included high-dose moxifloxacin or a long regimen (20 months) that followed the 2011 WHO guidelines.

The membrane-bound serine proteases prostasin and matriptase and the Kunitz-type protease inhibitors HAI-1 and HAI-2 are all expressed in human skin and may form a tightly regulated proteolysis network, contributing to skin pathophysiology. Evidence from other systems, however, suggests that the relationship between matriptase and prostasin and between the proteases and the inhibitors can be context-dependent. In this study the in vivo zymogen activation and protease inhibition status of matriptase and prostasin were investigated in the human skin.

Background And Purpose: Magnetic susceptibility values of multiple sclerosis lesions increase as they change from gadolinium-enhancing to nonenhancing. Can susceptibility values measured on quantitative susceptibility mapping without gadolinium injection be used to identify the status of lesion enhancement in surveillance MR imaging used to monitor patients with MS?

Materials And Methods: In patients who had prior MR imaging and quantitative susceptibility mapping in a current MR imaging, new T2-weighted lesions were evaluated for enhancement on conventional T1-weighted imaging with gadolinium, and their susceptibility values were measured on quantitative susceptibility mapping. Receiver operating characteristic analysis was used to assess the diagnostic accuracy of using quantitative susceptibility mapping in distinguishing new gadolinium-enhancing from new nonenhancing lesions.
