Modeling the Probability of HIV Infection over Time in High-Risk Seronegative Participants Receiving Placebo in Five Randomized Double-Blind Placebo-Controlled HIV Pre-Exposure Prophylaxis Trials: A Patient-Level Pooled Analysis.

The World Health Organization recommends pre-exposure prophylaxis (PrEP) for individuals at substantial risk of HIV infection. The aim of this analysis is to quantify the individual risk of HIV infection over time, using a large database of high-risk individuals (n = 5583). We used data from placebo recipients in five phase III PrEP trials: iPrEx, conducted in men who have sex with men and transgender women; VOICE, conducted in young women at high sexual risk; Partners PrEP, conducted in HIV serodiscordant heterosexual couples; TDF2, conducted in high-risk heterosexual men and women; and BTS, conducted in persons who inject drugs.

Use of a Novel Standardized Administration Protocol Reduces Agitation Pro Re Nata (PRN) Medication Requirements: The Birmingham Agitation Management (BAM) Initiative.

Background: Agitation management is a principal challenge on inpatient psychiatric units. Overreliance on common prescribing strategies of pro re nata (PRN) medication administration is problematic, given the tendencies to have overlapping or unclear indications.

Objective: Piloted project to determine whether a standardized protocol for agitation intervention may reduce PRN medication administration.

Paliperidone-Associated Sialorrhea: A Case Report With Review of Current Literature.

Purpose/background: Antipsychotic-associated sialorrhea is a problematic adverse effect with potentially negative consequences on quality of life and medication adherence. While clozapine is the antipsychotic that is most associated with sialorrhea, there have been published reports of other second-generation antipsychotics associated with sialorrhea, including aripiprazole, olanzapine, quetiapine, and risperidone. Although drooling is mentioned within the package insert for paliperidone, to date there have been minimal published reports in which paliperidone is implicated as the offending agent.

Academic Medical Centers Experienced Higher Rates of Post-Operative Health-Care-Associated Infections during the COVID-19 Pandemic: A Post Hoc Analysis of an Eastern Association for the Surgery of Trauma Multicenter Trial.

We sought to examine health-care-associated infections (HAIs) among patients undergoing an appendectomy at academic medical centers (AMCs) and non-AMCs during the coronavirus disease 2019 (COVID-19) peri-pandemic. We hypothesized that AMCs would have higher rates of post-operative HAIs during the first wave of the pandemic. We performed a post hoc analysis of a prospective, observational, multi-center study of patients aged >18 years who underwent an appendectomy for acute appendicitis before (pre-CoV), during (CoV), and after pandemic restrictions were lifted (post-CoV).

Evidence of Clinical Impact Supports a New Petition for Medicare Coverage of 2-[18F]Fluoro-2-Deoxy-D-Glucose Positron Emission Tomography/Computed Tomography in the Evaluation of Staphylococcus aureus Bacteremia: A Focused Literature Review and Call to Action.

Staphylococcus aureus bacteremia (SAB) causes considerable morbidity and mortality and requires comprehensive assessment for metastatic infection. The roles of routine imaging beyond echocardiography in SAB, including 2-[18F]fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (18F-FDG-PET/CT), remain contentious. We performed a literature review of studies reporting impact of 18F-FDG-PET/CT on the clinical management or outcomes of SAB published through 1 March 2022.

Comorbidity Trends in Patients Requiring Sternectomy and Reconstruction: Updated Data Analysis From 2005 to 2020.

Introduction: Comorbidity trends after median sternectomy were studied at our institution by Vasconze et al (Comorbidity trends in patients requiring sternectomy and reconstruction. Ann Plast Surg. 2005;54:5).

Characterizing HIV-Preventive, Plasma Tenofovir Concentrations-A Pooled Participant-level Data Analysis From Human Immunodeficiency Virus Preexposure Prophylaxis Clinical Trials.

Background: Daily dosing of tenofovir disoproxil fumarate, with or without emtricitabine, has high efficacy in preventing human immunodeficiency virus (HIV) infection when individuals are adherent. The target protective plasma concentration of tenofovir (TFV), however, is not fully understood. The aim of this study is to estimate the protective TFV plasma concentration.

Robotic Resection of Pulmonary Sequestration With Fluorescence Image Guidance.

We present the case of a 21-year-old woman with intralobar pulmonary sequestration in the right lower lobe. Minimally invasive robotic resection of the sequestration was performed to limit the loss of normal-functioning lung. This case also demonstrates the use of indocyanine green fluorescence guidance for demarcation of the sequestration.

Impact of COVID-19 on Hematology-Oncology Trainees: A Quantitative and Qualitative Assessment.

Purpose: Graduate medical and research training has drastically changed during the COVID-19 pandemic, with widespread implementation of virtual learning, redeployment from core rotations to the care of patients with COVID-19, and significant emotional and physical stressors. The specific experience of hematology-oncology (HO) fellows during the COVID-19 pandemic is not known.

Methods: We conducted a mixed-methods study using a survey of Likert-style and open-ended questions to assess the training experience and well-being of HO fellows, including both clinical and postdoctoral trainee members of the American Society of Hematology and ASCO.

Communicating About Time-Limited Trials.

Time-limited trials (TLTs) are used in the management of critical care patients undergoing potentially nonbeneficial interventions to improve prognostication and build trust and consensus between family and intensivists. When these trials are not well defined and executed, discordant views of the patient's prognosis, conflict, and continuation of nonbeneficial care can arise. The mnemonic TIME (truth about uncertainty in prognosis, interval of time, measurement of improvement, and end or extend) can help facilitate clear communication surrounding TLTs.

Critical Success Factors for Addressing Discharge Inefficiency at a Large Academic Medical Center: A Lean Six Sigma Approach.

Background: Delayed discharges can be a systemic issue. Understanding the systemic factors that contribute to discharge inefficiencies is essential to addressing discharge inefficiencies.

Purpose: This article reports on a Lean Six Sigma approach and the process to identifying inefficiencies and systemic barriers to early discharge in a large US academic medical center.

Cardiac natriuretic peptide deficiency sensitizes the heart to stress-induced ventricular arrhythmias via impaired CREB signalling.

Aims: The cardiac natriuretic peptides [atrial natriuretic peptide (ANP) and B-type natriuretic peptide (BNP)] are important regulators of cardiovascular physiology, with reduced natriuretic peptide (NP) activity linked to multiple human cardiovascular diseases. We hypothesized that deficiency of either ANP or BNP would lead to similar changes in left ventricular structure and function given their shared receptor affinities.

Methods And Results: We directly compared murine models deficient of ANP or BNP in the same genetic backgrounds (C57BL6/J) and environments.

Percutaneous Retrieval of Venous Bullet Embolism.

Purpose: Bullet fragment embolization is a rare but potentially fatal complication of traumatic gunshot injury. Herein, we present a case of a patient who demonstrated migration of a bullet fragment from the lower chest into the left common iliac vein. Continual identification of foreign bodies on trauma imaging is of the utmost importance.

High Fructose Corn Syrup-Moderate Fat Diet Potentiates Anxio-Depressive Behavior and Alters Ventral Striatal Neuronal Signaling.

The neurobiological mechanisms that mediate psychiatric comorbidities associated with metabolic disorders such as obesity, metabolic syndrome and diabetes remain obscure. High fructose corn syrup (HFCS) is widely used in beverages and is often included in food products with moderate or high fat content that have been linked to many serious health issues including diabetes and obesity. However, the impact of such foods on the brain has not been fully characterized.

Sustaining peer support groups: Insights from women living with HIV in rural Kenya.

Objective: As HIV transitions to a chronic disease, measures that foster continued health are critical. Peer support groups can help in reducing stigma and ensuring wellbeing for those living with HIV. The purpose of our study was to gain an understanding of the ways in which women living with HIV in rural areas sustain peer support groups.

Development of the University Postoperative Obstructive Sleep Apnea Protocol (UPOP).

Purpose: The purpose of this project was to retrospectively analyze medical records to determine the relationship between surgical patients with obstructive sleep apnea (OSA) risk factors and the occurrence of a critical respiratory event (CRE) in the postanesthesia care unit (PACU), and to subsequently develop a protocol for postoperative care. Although OSA is prevalent among the surgical population, research has primarily focused on preoperative identification and tailored perioperative care with limited application of standardized postoperative OSA management.

Design: Surgical charts were retrospectively reviewed between April 1, 2019 and June 31, 2019.

The American College of Surgeons Geriatric Surgery Verification Program and the Practicing Colorectal Surgeon.

The population is aging and older adults are increasingly undergoing surgery. Colorectal surgeons need to understand the risks inherent in the care of older adults and identify concrete ways to improve the quality of care for this vulnerable population. Goals for the practicing colorectal surgeon include: 1) introduce the American College of Surgeons' (ACS) Geriatric Surgery Verification (GSV) Program and understand the intersection with colorectal surgery, 2) examine the 30 evidence-based GSV standards and how they can achieve better outcomes after colorectal surgery, and 3) outline the value and benefits for colorectal surgeons of implementing such a program.

Flat sticker as a mobile airway foreign body: A case report and review of the literature.

Diagnosis of an airway foreign body in the setting of an unwitnessed aspiration event remains a challenge for physicians in the emergency setting. We describe a case of a 2-year-old male who presented to the emergency department with atypical symptoms resulting from ingestion and aspiration of a large, flat sticker. The airway foreign body remained in place for over 24 hours despite obtaining appropriate airway imaging, and the object was later removed without complication via rigid bronchoscopy in the operating room.
