Purpose: Pediatric patients with spina bifida often experience neurogenic bowel dysfunction. Although cecostomy tubes could improve bowel continence, their effectiveness is not well established in this population. The aims of this study were to better understand the effectiveness of cecostomy tubes relative to other management strategies (between-subject) and to explore their effectiveness among patients who received these placements (within-subject).

Hematopoietic stem cell transplantation (HSCT) represents a consolidated therapeutic strategy for high-risk pediatric acute lymphoblastic leukemia (ALL), offering the potential for curative treatment. This manuscript delves into the debate around the more universal application of HSCT for pediatric ALL in the modern era, considering the ubiquitous availability of suitable donors. In fact, despite significant advancements in chemotherapy, targeted therapy, and immunotherapy, a subset of pediatric patients with ALL with high-risk features or relapse continue to encounter poor prognostic outcomes.

Whereas living representatives of Pseudosuchia, crocodylians, number fewer than 30 species, more than 700 pseudosuchian species are known from their 250-million-year fossil record, displaying far greater ecomorphological diversity than their extant counterparts. With a new time-calibrated tree of >500 species, we use a phylogenetic framework to reveal that pseudosuchian evolutionary history and diversification dynamics were directly shaped by the interplay of abiotic and biotic processes over hundreds of millions of years, supported by information theory analyses. Speciation, but not extinction, is correlated with higher temperatures in terrestrial and marine lineages, with high sea level associated with heightened extinction in non-marine taxa.

Article Synopsis
  • Living in disadvantaged neighborhoods usually leads to worse healthcare outcomes, and the Area Deprivation Index (ADI) measures socioeconomic disadvantage based on factors like income and education.
  • A study of 543 head and neck cancer patients found that their ADI scores did not significantly correlate with tumor characteristics, loss to follow-up, or cancer recurrence.
  • However, missing clinic appointments was linked to a higher likelihood of loss to follow-up, suggesting that attendance at appointments is important for patient outcomes.

Article Synopsis
  • Early ultrasound examinations in pregnant mares are generally infrequent after initial diagnosis, but this case highlights the importance of ongoing monitoring.
  • A 17-year-old Thoroughbred mare carrying a mule fetus was extensively examined via transrectal ultrasound at 186 days of gestation, revealing multiple fetal abnormalities, including congenital cataracts and intrauterine growth restriction.
  • Ultimately, the pregnancy ended with an induced abortion at 272 days due to fetal complications, illustrating the effectiveness of ultrasound in diagnosing and managing equine fetal health issues.

Introduction: Paternal mental health has been associated with adverse consequences on offspring psychosocial development, and family environmental factors may partly explain those associations. To clarify this, we need comprehensive prospective studies, particularly in middle-childhood when the child enters school and is expected to make use of behavioral and cognitive skills as part of their interactions and learning.

Method: Using data from a sub-sample of the prospective 3D birth cohort study comprised of mother-father-child triads, and a follow-up of the parents and the children at 6-8 years of age ( = 61; 36 boys, 25 girls), we examined whether paternal anxious and depressive symptoms measured during the pregnancy period (i.

Introduction: Eribulin was approved by the FDA in 2010 for the treatment of metastatic breast cancer (MBC) in the United States (US). More recently, several immuno-oncology (IO) and antibody-drug conjugate (ADC) regimens have been approved for MBC. We assessed the treatment patterns and clinical outcomes in MBC patients treated with eribulin following treatment with an IO or ADC in US clinical practice.

Vinyasa yoga is moderate-intensity physical activity, yet physiological responses are poorly characterized. The purpose of this study was to examine the effect of a vinyasa yoga session on autonomic/cardiovascular functioning in healthy adults. A randomized crossover design took place at the Physical Activity and Weight Management laboratory (Pittsburgh, PA; n = 18), and included two experimental conditions: 60 minutes of vinyasa yoga or a seated control, and measurements were taken at baseline, 5-minutes, and 65-minute post-conditions.

Objective: Sexual assault perpetration remains prevalent among young men, and emotion regulation (ER) is a prominent contributor to sexual assault perpetration among young men experiencing anger or sexual arousal. However, little is known about the specific ER strategies which men use when perpetrating. Thus, the present study used latent profile analysis to group men into profiles based on their in-the-moment use of several ER strategies during two, hypothetical sexual situations: one which induced anger and another which induced sexual arousal.

Background: Longitudinal EEG recorded by implanted devices is critical for understanding and managing epilepsy. Recent research reports patient-specific, multi-day cycles in device-detected epileptiform events that coincide with increased likelihood of clinical seizures. Understanding these cycles could elucidate mechanisms generating seizures and advance drug and neurostimulation therapies.

The Coronavirus Disease 2019 (COVID-19) pandemic has caused unprecedented disruption in health care systems and may continue to do so. Nurses, the largest contingent of the nation's health care workforce, have borne the brunt of those disruptions, which have caused increased workload and resultant occupational stress. This study identified differences in nurses' occupational stress by practice specialty, time spent caring for patients with COVID-19, and nurses' demographic characteristics.

Selenium (Se) is an essential micronutrient that is found naturally in proteins, nucleic acids, and natural products. Unlike selenoproteins and selenonucleic acids, little is known about the structures of biosynthetic enzymes that incorporate Se into small molecules. Here, we report the X-ray crystal structure of SenB, the first known Se-glycosyltransferase that was recently found to be involved in the biosynthesis of the Se-containing metabolite selenoneine.

SUMMARYAntibiotic persistence, or the ability of small subsets of bacteria to survive prolonged antibiotic treatment, is an underappreciated cause of antibiotic treatment failure. Over the past decade, researchers have discovered multiple different stress responses and mechanisms that can promote antibiotic persistence. However, many of these studies have been completed in culture-based systems that fail to truly replicate the complexities of the host environment, and it is unclear whether the mechanisms defined in studies are applicable during host infection.

Article Synopsis
  • Older adults facing emergency general surgery (EGS) are at an increased risk of adverse outcomes due to age-related factors (geriatric vulnerability) and social determinants of health linked to their neighborhoods (neighborhood vulnerability).
  • Research showed that higher geriatric vulnerability substantially raises the risk of death, especially in more vulnerable neighborhoods, with rates increasing by up to 15 times compared to less vulnerable areas.
  • The study highlighted that these risks are even greater for racial and ethnic minority patients, indicating that both individual health factors and social conditions significantly impact EGS outcomes among older adults.

Chromogranin A (CgA) is a well-known biomarker for neuroendocrine tumors (NETs). However, due to its non-specificity, a proper assessment of CgA test results requires a detailed knowledge of the factors, conditions, and medications influencing its serum concentration. We describe a case of a 61-year-old patient presenting with a mass suspicious of a gastrointestinal NET and an exceedingly high level of serum CgA persistent after mass resection.
