Objective: We examined the feasibility and clinical outcomes of implementing a brief intervention for treating posttraumatic stress disorder (PTSD) in persons with serious mental illness receiving services at a large, urban community mental health agency. The Brief, Relaxation, Education and Trauma Healing (BREATHE) program is a standardized, three-session intervention that targets PTSD symptoms through teaching breathing retraining and personalized psychoeducation about trauma and PTSD.

Method: A total of 60 clinicians were trained in the BREATHE intervention throughout the agency, which was offered to 233 clients who screened positive for probable PTSD.

Article Synopsis
  • - The study compares the safety of narrow-spectrum vs. broad-spectrum antibiotics for treating community-acquired pneumonia (CAP) in healthy adults aged 18-64, revealing that broad-spectrum antibiotics have a higher risk of adverse drug events (ADEs).
  • - An analysis of 145,137 patients showed that broad-spectrum antibiotics like fluoroquinolones and β-lactams were linked to increased risks of issues such as nausea, diarrhea, and vulvovaginal infections compared to macrolide monotherapy.
  • - The findings highlight the need for better antimicrobial stewardship to encourage the careful use of antibiotics, particularly broad-spectrum ones, to minimize the risk of harmful side effects.

Background: Urinary tract infections (UTI) affect approximately 250 million people annually worldwide. Patients often experience a cycle of antimicrobial treatment and recurrent UTI (rUTI) that is thought to be facilitated by a gut reservoir of uropathogenic (UPEC).

Methods: 125 patients with UTI caused by an antibiotic-resistant organism (ARO) were enrolled from July 2016 to May 2019 in a longitudinal, multi-center cohort study.

Background: Sepsis is a major cause of morbidity and mortality worldwide. When selecting empiric antibiotics for sepsis, clinicians are encouraged to use local resistance rates, but their impact on individual outcomes is unknown. Improved methods to predict outcomes are needed to optimize treatment selection and improve antibiotic stewardship.

Patient advocates, referring to those individuals that have been diagnosed with the disease for which they advocate, are essential stake holders in healthcare. For those facing the stages of being diagnosed with Inflammatory Breast Cancer (IBC), the "call to advocate" is an immediate response to being diagnosed with a rare and aggressive disease that progresses rapidly, often in a matter of weeks or months. There is a great stigma and bias in the medical community that has inhibited the education and study of IBC.

Background: SARS-CoV-2 vaccines are effective at reducing symptomatic and asymptomatic COVID-19. Limited studies have compared symptoms, threshold cycle (Ct) values from reverse transcription (RT)-PCR testing, and serological testing results between previously vaccinated vs unvaccinated populations with SARS-CoV-2 infection.

Methods: Healthcare personnel (HCP) with a positive SARS-CoV-2 RT-PCR test within the previous 14 to 28 days completed surveys including questions about demographics, medical conditions, social factors, and symptoms of COVID-19.

Objectives: Aminoglycosides and β-lactams have been recommended for treatment of sepsis/septic shock despite a lack of mortality benefit. Previous studies have examined resistance emergence for the same bacterial isolate using old dosing regimens and during a narrow follow-up window. We hypothesised that combination regimens employing aminoglycosides will decrease the cumulative incidence of infections due to multidrug-resistant (MDR) Gram-negative bacilli (GNB) compared with β-lactams alone.

Background: Patients prefer medical communication including both hopefulness and realism, though health-care professional (HCPs) struggle to balance these. Providers could thus benefit from a detailed personal understanding of hope, allowing them to model and convey it to patients. Additionally, given that hope is associated with lower levels of burnout, HCPs may benefit from tools designed to enhance their own personal hopefulness.
