Background And Methods: Colorectal cancer (CRC) treatment can influence health-related quality of life (HRQOL). This study examined HRQOL among older adults undergoing CRC treatment, and the conditional effects of race, ethnicity, and primary language. We conducted a retrospective cohort study of Medicare Advantage enrollees ≥ 65 years old who completed the Medicare Health Outcomes Survey (MHOS) (2016-2020).

Introduction: Despite remarkable progress, gender inequality in medicine remains a significant issue. This disparity extends beyond clinical practices and educational programs; it is also evident in the recognition and awards received by surgeons. Underrepresentation of women in Surgical Society awards is a multi-layered issue that needs a holistic approach since these awards are used to hire, promote, and advance surgeons.

Background: Postoperative hypocalcemia is a common complication of thyroid and parathyroid surgery. Patients with prior gastric bypass face increased risk of postoperative hypocalcemia, but the impact of other malabsorptive conditions is not well understood. In this study, we evaluated the relationship between multiple medical and surgical malabsorptive states and hypocalcemia after thyroid and parathyroid surgery.

Importance: Socially vulnerable patients with symptomatic cholelithiasis are more likely to face barriers to accessing surgical care. This barrier to access can lead to delays in treatment, the need for emergent cholecystectomy, and worse outcomes.

Objectives: To determine the effectiveness of telemedicine vs in-person surgical consultation on access to elective cholecystectomy in socially vulnerable populations and to evaluate the association of scheduling navigation with access to elective cholecystectomy in these populations.

Purpose: Extramural funding is critical to career success and advancement in academic surgery, and surgical residents can apply for both societal and federal funding. Many federal funding mechanisms require proposals to be submitted before residents' formal research years.

Methods: To better understand the resident experience with grantsmanship, we distributed a validated grantsmanship self-efficacy assessment inventory for voluntary completion at our academic general surgery training program with 2 years of dedicated research.

Article Synopsis
  • Normohormonal primary hyperparathyroidism involves high calcium levels with normal parathyroid hormone, and previous studies indicated that a significant decrease in parathyroid hormone during surgery predicts successful treatment and helps prevent low calcium levels post-surgery.
  • In a study analyzing over 1,000 patients, findings showed similar cure rates between normohormonal (94%) and classic primary hyperparathyroidism (92%), although the average decrease in hormone levels during surgery was lower in normohormonal cases.
  • When applying the earlier established thresholds for hormone reduction, the study confirmed high predictive values for successful treatment and low risk of hypocalcemia for both types of hyperparathyroidism.

Article Synopsis
  • Abdominal pain is a common reason adults go to the emergency room, but there isn’t a set way to figure out what’s wrong.
  • We looked at data from visits over 12 years to see how different age groups (like younger and older adults) were treated for this problem.
  • More people are getting CT scans, especially older adults, but many still got X-rays, which aren't very good at finding serious issues.

Background: Night float rotations are associated with decreased feedback, educational conference attendance, and operative time. Interns are also more isolated and spend less time on teams. We therefore developed a novel post night shift initiative to address these shortcomings and examined its impact on the educational experience and sense of belonging among interns.

Background: Enrollment of Medicare beneficiaries in medicare advantage (MA) plans has been steadily increasing. Prior research has shown differences in healthcare access and outcomes based on Medicare enrollment status. This study sought to compare utilization of minimally invasive colorectal cancer (CRC) surgery and postoperative outcomes between MA and Fee-for-Service (FFS) beneficiaries.

Background: In September 2022, a summit was convened by the American Board of Surgery (ABS) to discuss competency-based reform in surgical education. A key output of that summit was the recommendation that the prior work of the Blue Ribbon I Committee convened 20 years earlier be revived. With leadership from the American College of Surgeons (ACS) and the American Surgical Association (ASA), the Blue Ribbon Committee (BRC) II was subsequently convened.

Article Synopsis
  • The study aimed to understand how certain tiny molecules called microRNAs (miRNAs) are connected to a condition called Primary Hyperparathyroidism (PHPT), which affects bones.
  • They looked at women who have PHPT and compared their miRNA levels to women who do not have this condition.
  • The researchers found 9 specific miRNAs that were different in people with PHPT, and these were linked to parathyroid hormone levels, which plays a role in how bones are remodeled, but they did not strongly relate to bone density.

Large tumor size is associated with poorer outcomes in well-differentiated thyroid cancer, yet it remains unclear whether size >4 cm alone confers increased risk, independent of other markers of aggressive disease. The goal of this study was to assess the relationship between tumor size, other high-risk histopathological features, and survival in well-differentiated thyroid cancer and to evaluate the significance of 4 cm as a cutoff for management decisions. Patients with well-differentiated thyroid cancer were identified from the National Cancer Database (2010-2015) and categorized by tumor size (i.

Importance: Adverse patient events are inevitable in surgical practice.

Objectives: To characterize the impact of adverse patient events on surgeons and trainees, identify coping mechanisms, and assess whether current forms of support are sufficient.

Design, Setting, And Participants: In this mixed-methods study, a validated survey instrument was adapted and distributed to surgical trainees from 7 programs, and qualitative interviews were conducted with faculty from 4 surgical departments in an urban academic health system.

Objective: To determine the association between post-discharge mental healthcare and odds of readmission after emergency general surgery (EGS) hospitalization for patients with serious mental illness (SMI).

Background Data: A mental health visit (MHV) after medical hospitalization is associated with decreased readmissions for patients with SMI. The impact of a MHV after surgical hospitalization is unknown.

Background: Federal regulations require a history and physical (H&P) update performed 30 days or less before a planned procedure. We evaluated the use and burdens of H&P update visits by determining impact on operative management, suitability for telehealth, and visit time and travel burden.

Study Design: We identified H&P update visits performed in our health system during 2019 for 8 surgical specialties.

Objective: To compare general surgery outcomes at flagship systems, flagship hospitals, and flagship hospital affiliates versus matched controls.

Summary Background Data: It is unknown whether flagship hospitals perform better than flagship hospital affiliates for surgical patients.

Methods: Using Medicare claims for 2018 to 2019, we matched patients undergoing inpatient general surgery in flagship system hospitals to controls who underwent the same procedure at hospitals outside the system but within the same region.

Introduction: Primary hyperparathyroidism (PHPT) is defined by autonomous parathyroid hormone secretion, which has broad physiologic effects. Parathyroidectomy is the only cure and is recommended for patients demonstrating symptomatic disease and/or end organ damage. However, there may be a benefit to intervening before the development of complications.
