Objective: To determine whether nicotinamide use results in an increase of MACE.

Background: The gut microbiome has emerged as a clear player in health and disease, in part by mediating host response to environment and lifestyle. The urobiome (microbiota of the urinary tract) likely functions similarly. However, efforts to characterize the urobiome and assess its functional potential have been limited due to technical challenges including low microbial biomass and high host cell shedding in urine.

Article Synopsis
  • - Voriconazole exposure is linked to a higher incidence of skin cancer among organ transplant recipients, but the role of genetic variations in drug metabolism (specifically CYP2C19) was unclear until this study.
  • - A retrospective analysis of 1,739 transplant patients revealed that 134 had voriconazole exposure, and both exposure and metabolizer status significantly influenced skin cancer rates (p < 0.01).
  • - Rapid metabolizers of voriconazole exhibited a notably increased risk for developing squamous cell carcinomas (SCC), with faster cancer onset compared to non-exposed patients (hazard ratio of 1.78 for overall skin cancer and 1.83 for SCC specifically).

Article Synopsis
  • Bimekizumab, a monoclonal antibody targeting IL-17F and IL-17A, is being tested as a treatment for moderate-to-severe hidradenitis suppurativa, a condition with limited treatment options.
  • The BE HEARD I and II trials were 48-week, randomized, double-blind studies that evaluated the efficacy and safety of various dosing regimens of bimekizumab compared to a placebo in over 1,000 patients.
  • Results showed significant improvement in patients receiving bimekizumab every 2 weeks, meeting the primary efficacy goal of at least a 50% reduction in disease symptoms by week 16.

Objective: Describe the frequency and timing of the treatment of multiple skin cancers in individual patients over time.

Design: Longitudinal claims and electronic health record-based cohort study.

Voriconazole exposure is associated with skin cancer, but it is unknown how the full spectrum of its metabolizer phenotypes impacts this association. We conducted a retrospective cohort study to determine how variation in metabolism of voriconazole as measured by metabolizer status of CYP2C19 is associated with the total number of skin cancers a patient develops and the rate of development of the first skin cancer after treatment. There were 1,739 organ transplant recipients with data on CYP2C19 phenotype.

The mammalian brain controls heat generation and heat loss mechanisms that regulate body temperature and energy metabolism. Thermoeffectors include brown adipose tissue, cutaneous blood flow and skeletal muscle, and metabolic energy sources include white adipose tissue. Neural and metabolic pathways modulating the activity and functional plasticity of these mechanisms contribute not only to the optimization of function during acute challenges, such as ambient temperature changes, infection and stress, but also to longitudinal adaptations to environmental and internal changes.

Article Synopsis
  • Cognitive dysfunction is frequently observed after traumatic brain injury (TBI), with a clear link between TBI severity and the extent of cognitive issues in the long term (around 6 months post-injury).
  • A study aimed to examine the occurrence of cognitive dysfunction across various cognitive areas like processing speed, memory, and executive function in TBI patients from trauma centers.
  • The research included 1,057 TBI patients and 327 control participants, revealing that many TBI patients performed comparably to controls, with around 49% to 67% demonstrating cognitive performance within 1.5 standard deviations of the control group.

Importance: Traumatic brain injury (TBI) is associated with persistent functional and cognitive deficits, which may be susceptible to secondary insults. The implications of exposure to surgery and anesthesia after TBI warrant investigation, given that surgery has been associated with neurocognitive disorders.

Objective: To examine whether exposure to extracranial (EC) surgery and anesthesia is related to worse functional and cognitive outcomes after TBI.

Transient events during development can exert long-lasting effects on organismal lifespan. Here we demonstrate that exposure of Caenorhabditis elegans to reactive oxygen species during development protects against amyloid-induced proteotoxicity later in life. We show that this protection is initiated by the inactivation of the redox-sensitive H3K4me3-depositing COMPASS complex and conferred by a substantial increase in the heat-shock-independent activity of heat shock factor 1 (HSF-1), a longevity factor known to act predominantly during C.

Simian immunodeficiency virus (SIV), which originated in African monkeys, crossed the species barrier into humans and ultimately gave rise to HIV and the global HIV/AIDS epidemic. While SIV infects over 40 primate species in sub-Saharan Africa, testing for RNA viruses in wild primate populations can be challenging. Optimizing field-friendly methods for assessing viral presence/abundance in non-invasively collected biological samples facilitates the study of viruses, including potentially zoonotic viruses, in wild primate populations.

Article Synopsis
  • The study investigates the long-term safety of bimekizumab (BKZ) for patients with moderate-to-severe plaque psoriasis over three years, based on data from multiple trials.
  • Out of 1,495 patients analyzed, the overall rate of treatment-emergent adverse events (TEAEs) was 175.5 per 100 patient-years, which decreased with longer treatment exposure.
  • Common TEAEs included mild cases of nasopharyngitis and oral candidiasis, with serious adverse events remaining rare, indicating that BKZ's safety profile is stable over time.

Each year in the United States, ∼2.7 million persons seek medical attention for traumatic brain injury (TBI), of which ∼85% are characterized as being mild brain injuries. Many different cell types in the brain are affected in these heterogeneous injuries, including neurons, glia, and the brain vasculature.

Background: Urine is routinely evaluated in dogs to assess health. Reference ranges for many urine properties are well established, but the scope of variation in these properties over time within healthy dogs is not well characterized.

Objectives: Longitudinally characterize urine properties in healthy dogs over 3 months.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in humans in late 2019 and spread rapidly, becoming a global pandemic. A zoonotic spillover event from animal to human was identified as the presumed origin. Subsequently, reports began emerging regarding spillback events resulting in SARS-CoV-2 infections in multiple animal species.

Introduction: As the utilization of metabolic and bariatric surgery (MBS) continues to rise, it is important to address the nutritional needs of women who had MBS who become pregnant. Not meeting those nutritional needs could lead to complications associated with malnutrition. To better understand the relationship between MBS, pregnancy, and malnutrition, this study sought to determine whether differences exist in the presence of malnutrition during pregnancy in women with a history of MBS compared to women without a history of MBS.

The mediobasal hypothalamus (MBH) contains heterogeneous neuronal populations that regulate food intake and energy expenditure. However, the role of MBH neurons in the neural control of thermoeffector activity for thermoregulation is not known. This study sought to determine the effects of modulating the activity of MBH neurons on the sympathetic outflow to brown adipose tissue (BAT), BAT thermogenesis, and cutaneous vasomotion.

Oxidation of fat by brown adipose tissue (BAT) contributes to energy balance and heat production. During cold exposure, BAT thermogenesis produces heat to warm the body. Obese subjects and rodents, however, show impaired BAT thermogenesis to the cold.

Certified nursing assistants (CNAs) provide 80% of direct care in long-term care settings and are critical to maintaining resident well-being. Arts-based approaches to enhancing meaningful engagement have the potential to empower CNA ownership in the process of improving patient-centered care. We held a series of focus groups with CNAs (n = 14) to adapt arts-based creative caregiving (CCG) techniques for use in long-term care.
