Pain and psychological stress are intricately linked, with sex differences evident in disorders associated with both systems. Glutamatergic signalling in the central nervous system is influenced by gonadal hormones via the hypothalamic-pituitary-adrenal axis and is central in pain research. Emerging evidence supports an important role for the gut microbiota in influencing pain signalling.

Criminal legal system involvement (CLI) is a critical social determinant of health that lies at the intersection of multiple sources of health disparities. The COVID-19 pandemic exacerbates many of these disparities, and specific vulnerabilities faced by the CLI population. This study investigated the prevalence of COVID-19-related misinformation, as well as its relationship with COVID-19 information sources used among Americans experiencing CLI.

Intussusception, which is characterized by the invagination of one portion of the gastrointestinal tract into an adjacent segment, is an uncommon cause of abdominal pain in adults. Given that it is typically associated with identifiable pathological abnormalities, intussusception can pose a diagnostic challenge in adults due to its rarity and nonspecific symptomatology. This report presents a unique case of multiple small bowel intussusceptions in a 20-year-old female, which emphasizes the importance of clinical suspicion and advanced imaging for an accurate diagnosis.

Gastrointestinal bleeding can be manifested as a variety of symptoms and, often, it is difficult to classify as upper or lower gastrointestinal bleeding on mere symptomatology. This is a case report of a similar kind of patient who initially was diagnosed with fresh per rectum bleeding, subsequently diagnosed as bleeding angiodysplasia in duodenal diverticulum by a series of investigations and management including urgent oesophageal-gastroduodenoscopy (OGD), laparotomy, followed by computerized tomography-angiogram. As diagnosis was established after laparotomy, the patient was kept intubated and IR selective embolization was performed.

Background And Aim: Relative to men, women present with pain conditions more commonly. Although consistent differences exist between men and women in terms of physiological pain sensitivity, the underlying mechanisms are incompletely understood and yet could inform the development of effective sex specific treatments for pain. The gut microbiota can modulate nervous system functioning, including pain signaling pathways.

Background: Fidelity assessment tools can assess whether a program embraces a core set of principles and performs well. A quality fidelity tool with valid scales can be a feedback loop to identify areas that need further work to improve the program. Using data collected from 1816 correctional and reentry programs in the United States in the construction sample and 761 programs in the confirmation sample, this study examined the internal consistency of the Risk-Need-Responsivity (RNR) Program Tool, an online resource to capture information about structural features of a program.

Targeting the gut microbiome as an effective therapeutic strategy for psychological disorders has shown promise in recent years. Variation in the composition of the microbiota and restoration of a stable microbiome using targeted interventions (psychobiotics) including Bifidobacteria have shown promise in pre-clinical studies, but more human data is required on the potential health benefits of these live microorganisms Bifidobacterium including 1714 has been shown to dampen the effects of acute stress in humans. However, its effects over a period of prolonged stress have not been examined.

The microbiome-gut-brain-axis is a complex phenomenon spanning several dynamic systems in the body which can be parsed at a molecular, cellular, physiological and ecological level. A growing body of evidence indicates that this axis is particularly sensitive to the effects of stress and that it may be relevant to stress resilience and susceptibility. Although stress-induced changes in the composition of the microbiome have been reported, the degree of compositional change over time, which we define as volatility, has not been the subject of in-depth scrutiny.

A breast cancer diagnosis can be a life-changing and stressful experience that can lead to chronic mental health conditions such as posttraumatic stress disorder (PTSD). Greater than one-third of patients initially diagnosed with PTSD after a diagnosis of breast cancer continue to have persistent or worsening PTSD symptoms after 4 years. An emerging body of literature has indicated several key environmental and biological risk factors for PTSD among survivors of breast cancer.

Studies of the B cell repertoire suggest that early childhood influenza infections profoundly shape later reactivity by creating an "imprint" that impacts subsequent vaccine responses and may provide lasting protection against influenza strains within the same viral group. However, there is little known about how these early childhood influenza exposures shape CD4 T cell reactivity later in life. To investigate the effect of age on influenza-specific CD4 T cell specificity and functionality, reactivity in cohorts of 2 year old children and young adult subjects was compared.

Contingency management (CM) is a well-acknowledged behavioral approach for incentivizing changes in behavior and attitudes. A version of CM was piloted in four federal probation districts to determine whether systematically awarding points and rewards for key behaviors could be implemented and impact recidivism rates. A case controlled match design was conducted with a CM sample (referred to as Justice Steps (JSTEPS)) (n=128) who were individually matched to a comparison sample (n=128) on six variables related to recidivism.

The objective of this study was to determine whether implementing an outpatient infusion pathway (OIP) resulted in a decreased 30-day readmission rate after laparoscopic Roux-en-Y gastric bypass (LRYGB). Data were retrospectively gathered on all patients who underwent LRYGB at our institution between April 1, 2015, and March 31, 2016, after instituting an OIP (postinfusion group). Thirty-day readmission rate, length of stay, and 30-day mortality rate were compared with patients who underwent LRYGB between January 1, 2014, and December 31, 2014, before implementing the OIP (preinfusion group).
