Breastfeeding in metabolic and bariatric patients: a comprehensive guide for surgeons, patients, and the multidisciplinary team.

Since nearly 40% of metabolic and bariatric surgery (MBS) patients are individuals with the ability to bear children, many may seek to become pregnant or may be currently lactating when seeking surgery. While many patients plan to breastfeed, MBS patients are at high risk for premature cessation of breastfeeding. Limited literature exists on the impact of MBS on lactation and there are no established guidelines to help clinicians support and educate MBS patients about breastfeeding.

Variation in Long-Term Postoperative Mortality Risk by Race/Ethnicity After Major Non-cardiac Surgeries in the Veterans Health Administration.

Background: Few large sample studies have examined whether disparities, as measured by the proxy of race/ethnicity, are observed in long-term mortality after high-risk operations performed in a United States national health system. We compared operation year-related mortality risk by race/ethnicity after high-risk operative interventions among patients receiving care within the VHA.

Methods: From the Veterans Affairs Corporate Data Warehouse and Surgical Quality Improvement Program, data were retrieved for 426,695 patients undergoing high-risk surgical procedures in non-cardiac, general, vascular, thoracic, orthopedic, neurosurgery, and genitourinary specialties between 2000 and 2018.

Hospital resource index, race/ethnicity, and postoperative venous thromboembolism risk: A causal mediation analysis.

Background: We examined whether hospital resources mediated the association between race/ethnicity and postoperative VTE, in a national cohort.

Methods: National Inpatient Sample data were restricted to major abdominal surgeries (1993-2020) performed for malignancies. Hospital resource index was as a summary measure of hospital size, teaching status, and private payor proportions.

Racial and ethnic disparities in potentially inappropriate medication use in patients with dementia.

Introduction: Racial and ethnic disparities in potentially inappropriate medication (PIM) use among older adults with dementia are unclear.

Methods: Data were drawn from the baseline visits of participants who were ≥60 years old and diagnosed with dementia in the National Alzheimer's Coordinating Center Uniform Data Set (NACCUDS) recruited from National Institute on Aging (NIA)-funded Alzheimer's Disease Research Centers (ADCs) throughout the United States. PIM utilization was evaluated using the 2019 American Geriatrics Society Beers Criteria for PIM Use in Older Adults.

Medical residents' perceptions of group biases in medical decision making: a qualitative study.

Background: Systematic biases in group decision making (i.e., group biases) may result in suboptimal decisions and potentially harm patients.

What is diagnostic safety? A review of safety science paradigms and rethinking paths to improving diagnosis.

Diagnostic errors in health care are a global threat to patient safety. Researchers have traditionally focused diagnostic safety efforts on identifying errors and their causes with the goal of reducing diagnostic error rates. More recently, complementary approaches to diagnostic errors have focused on improving diagnostic performance drawn from the safety sciences.

Transcriptomic and proteomic analysis of tumor suppressive effects of GZ17-6.02 against mycosis fungoides.

Mycosis fungoides (MF) is the most common form of cutaneous T-cell lymphoma (CTCL). Despite having a wide variety of therapeutic agents available for the treatment of MF, patients often suffer from a significant decrease in quality of life and rarely achieve long-term remission or complete cure, highlighting a need to develop novel therapeutic agents for this disease. The present study was undertaken to evaluate the efficacy of a novel anti-tumor agent, GZ17-6.

Exploring Ward Team Handoffs of Overnight Admissions: Key Lessons from Field Observations.

Background: The diagnostic process is a dynamic, team-based activity that is an important aspect of ward rounds in teaching hospitals. However, few studies have examined how academic ward teams operate in areas such as diagnosis in the handoff of overnight admissions during ward rounds. This study draws key lessons from team interactions in the handoff process during ward rounds.

Scrutinizing the use of contrasted chest CTs in extremity sarcoma staging and surveillance.

Background: Since 2015, the American College of Radiology (ACR) has recommended staging for lung metastasis via chest computed tomography (CT) without contrast for extremity sarcoma staging and surveillance. The purpose of this study was to determine our institutional compliance with this recommendation.

Methods: This was a retrospective chart review of patients diagnosed with sarcoma in the extremities who received CT imaging of the chest for pulmonary staging and surveillance at our institution from 2005 to 2023.

Towards diagnostic excellence on academic ward teams: building a conceptual model of team dynamics in the diagnostic process.

Objectives: Achieving diagnostic excellence on medical wards requires teamwork and effective team dynamics. However, the study of ward team dynamics in teaching hospitals is relatively underdeveloped. We aim to enhance understanding of how ward team members interact in the diagnostic process and of the underlying behavioral, psychological, and cognitive mechanisms driving team interactions.

Deduced Respiratory Scores on COVID-19 Patients Learning from Exertion-Induced Dyspnea.

Dyspnea is one of the most common symptoms of many respiratory diseases, including COVID-19. Clinical assessment of dyspnea relies mainly on self-reporting, which contains subjective biases and is problematic for frequent inquiries. This study aims to determine if a respiratory score in COVID-19 patients can be assessed using a wearable sensor and if this score can be deduced from a learning model based on physiologically induced dyspnea in healthy subjects.

How team clinical reasoning occurs on ward rounds: Implications for learning.

Background: Ward rounds offer a rich environment for learning about team clinical reasoning. We aimed to assess how team clinical reasoning occurs on ward rounds to inform efforts to enhance the teaching of clinical reasoning.

Methods: We performed focused ethnography of ward rounds over a 6-week period, during which we observed five different teams.

Differential Response of Mycosis Fungoides Cells to Vorinostat.

Mycosis fungoides (MF) is the most common form of cutaneous T-cell lymphoma (CTCL) and is characterized by epidermotrophism of malignant CD4+ T-lymphocytes. When MF advances to a recurrent stage, patients require treatment with systemic therapies such as vorinostat, a histone deacetylase inhibitor. While vorinostat has been shown to exhibit anti-tumor activity in MF, its exact molecular mechanism has yet to be fully discerned.

Optimizing measurement of misdiagnosis-related harms using symptom-disease pair analysis of diagnostic error (SPADE): comparison groups to maximize SPADE validity.

Diagnostic errors in medicine represent a significant public health problem but continue to be challenging to measure accurately, reliably, and efficiently. The recently developed Symptom-Disease Pair Analysis of Diagnostic Error (SPADE) approach measures misdiagnosis related harms using electronic health records or administrative claims data. The approach is clinically valid, methodologically sound, statistically robust, and operationally viable without the requirement for manual chart review.

Prevalence and Causes of Diagnostic Errors in Hospitalized Patients Under Investigation for COVID-19.

Background: The COVID-19 pandemic required clinicians to care for a disease with evolving characteristics while also adhering to care changes (e.g., physical distancing practices) that might lead to diagnostic errors (DEs).

Lower-extremity pressure, staging, and grading thresholds to identify chronic limb-threatening ischemia.

Introduction: The Society for Vascular Surgery Threatened Limb Classification System ('WIfI') is used to predict risk of limb loss and identify peripheral artery disease in patients with foot ulcers or gangrene. We estimated the diagnostic sensitivity of multiple clinical and noninvasive arterial parameters to identify chronic limb-threatening ischemia (CLTI).

Methods: We performed a single-center review of 100 consecutive patients who underwent angiography for foot gangrene or ulcers.

Shared decision making with black patients: A scoping review.

Objective: The purpose of this review is to explore the breadth of research conducted on SDM in the care of Black patients.

Methods: We conducted a scoping review following the methodological framework outlined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. We searched articles related to original research on SDM in the care of Black patients in October 2022 using PubMed, Embase, and Google Scholar databases.

Construction of a Secondary Enclosure for UVB Irradiation of Mice.

UV irradiation is commonly used in murine models of skin cancers. Despite the popularity of using UVB rays to model photocarcinogenesis in animals, there is a lack of standardization in the secondary enclosures used to administer radiation. An appraisal of the literature also shows a general lack of details regarding the materials and procedures utilized in the fabrication of such enclosures.

Context matters: toward a multilevel perspective on context in clinical reasoning and error.

Context in diagnosis and management of patients is a vexing phenomenon in medicine and health professions education that can lead to unwanted variation in clinical reasoning performance and even errors that cause patient harm. Studies have examined individual-, team-, and system-level contextual factors, but the ways in which multiple contextual factors can interact, how both distracting and enabling factors can impact performance and error, and the boundaries between context and content information are not well understood. In this paper, we use a theory-based approach to enhance our understanding of context.

Using an experiential learning model to teach clinical reasoning theory and cognitive bias: an evaluation of a first-year medical student curriculum.

Background: Most medical students entering clerkships have limited understanding of clinical reasoning concepts. The value of teaching theories of clinical reasoning and cognitive biases to first-year medical students is unknown. This study aimed to evaluate the value of explicitly teaching clinical reasoning theory and cognitive bias to first-year medical students.

Neural correlates linking trauma and physical symptoms.

Trauma and chronic pain frequently co-occur, but the underlying neurological mechanisms are poorly understood. The current study investigated the neural correlates of stress and physical symptoms in trauma patients using functional magnetic resonance imaging (fMRI) and follow-up smartphone surveys. Participants were 10 patients diagnosed with Trauma- and Stressor-Related Disorders and 18 demographically-matched healthy controls who completed a fMRI stress provocation task in which they viewed stressful and neutral-relaxing images.

Unusual chondroblastoma of the hand with large extraosseous soft tissue component.

Chondroblastoma is a rare, benign primary cartilaginous bone tumor that typically arises in the epiphyses of the long bones. Radiologically, a well-defined lytic lesion with thin sclerotic margins is commonly found. The tumor is characterized histologically as an admixture of chondroblasts and multinucleated giant cells with chondroid matrix and pericellular calcifications.
