Challenges and recent advances in engineering the osteochondral interface.

Due to the high incidence of cartilage-related pathologies such as focal defects and osteoarthritis, strategies are needed to restore the structure and function of osteochondral tissue. Articular cartilage and bone have distinctly different properties, rendering challenging the engineering of a robust interface that reduces stress concentrations and delamination. The osteochondral interface, which consists of a tidemark, calcified cartilage, cement line, and surrounding tissues, has a unique structure and function, but there is a dearth of quantitative data to describe it.

Impact of postoperative residual disease on survival in epithelial ovarian cancer with consideration of recent frontline treatment advances: A systematic review and meta-analysis.

Background: Current treatment strategies for primary epithelial ovarian cancer (EOC) have significantly evolved, and the value of complete cytoreduction has not yet been reassessed. The study aimed to investigate the impact of residual disease after cytoreductive surgery for EOC on survival outcomes within the recent paradigm of frontline ovarian cancer treatment.

Methods: We searched relevant literature from the MEDLINE, Embase, and Cochrane Library databases to identify randomized controlled trials and prospective clinical trials of primary EOC published between 1 January 2000 and 22 September 2022.

Mesenchymal stem cells from human umbilical cord decrease inflammation and increase vascularization of induced apical periodontitis model in diabetes mellitus rats.

Objectives: to evaluate inflammation and vascularization in a model of apical periodontitis in diabetic Wistar rats through histopathological examination of blood vessels and immunohistochemical examination of interleukin 1b (IL-1b) and tumor necrosis factor-a (TNF-a).

Methodology: Diabetes was induced in 20 Wistar rats using multiple low-dose injections of streptozotocin (STZ) until blood glucose levels stabilized above 300 mg/dL, confirmed by glucometer. Under anesthesia, apical periodontitis was induced in the right mandibular first molars.

Correlation Between Medical School Performance and Receiving Awards in General Surgery Residency.

Importance: It is uncertain whether current measures of achievement during medical school predict exceptional performance during surgical residency. One surrogate of excellence during residency may be awards, especially those given for teaching and annual overall accomplishment.

Objective: Determine whether markers of superior performance during medical school documented in the Electronic Residency Application Service (ERAS) application and student record correlated with receiving awards during residency.

Evaluating predictors of mortality in octogenarians undergoing urgent or emergent trauma laparotomy.

Purpose: This study aimed to identify associated risk factors for mortality in octogenarian trauma patients undergoing urgent or emergent laparotomy (UEL).

Methods: Trauma patients ages 80-89 years-old undergoing UEL within 6-hours of arrival were included. A multivariable logistic regression analysis was performed to determine associated risk of mortality.

Mild and Severe Blood Alcohol Concentration Effects on Trauma and Traumatic Brain Injury Outcomes.

Introduction: Reported outcomes for trauma patients (TPs) with elevated blood alcohol concentration (BAC) have been mixed. Previous studies suggest that positive BAC might lead to lower venous thromboembolism (VTE) rates and mortality. This study expands upon these findings by examining the association of various levels of BAC, with additional emphasis on traumatic brain injury (TBI) patients.

Anemia and Transfusion Medicine.

Peri-operative anemia is a common condition encountered in adult surgical patients. It is increasingly recognized as a predictor of post-operative morbidity and mortality. Evaluation and treatment of anemia pre-operatively can reduce transfusion needs and potentially improve outcomes in surgical patients.

Reappraisal of the Previously Described False Localizing Sign at C1-2 in Cases of Spontaneous Intracranial Hypotension.

Background And Objectives: We present an illustrative case of spontaneous intracranial hypotension (SIH) in the setting of a suspected C1-2 cerebrospinal fluid (CSF) leak that was successfully treated with muscle, collagen, and epidural blood patch. We examined the literature to identify similar cases reporting Cl-2 retrospinal fluid collections identified on imaging in the setting of SIH and quantified the success of targeted treatment to this area despite previous reports that caution about a "C1-2 false localizing sign."

Methods: A systematic search was performed identifying cases of SIH resulting from CSF leak with C1-2 fluid collection observed on imaging.

External ear malformations and cardiac and renal anomalies: A systematic review and meta-analysis.

Context: External Ear Malformations (EEM) continue to be a common malformation seen in the pediatric patient population. This study aims to further elucidate the correlation between EEM and cardiac and renal anomalies.

Objective: A systematic review and meta-analysis to study the incidence of cardiac and renal anomalies associated with syndromic and isolated (EEM).

Higher Expression of Talin-1 is Associated With Less Aggressive Tumor Behavior in Pancreatic Cancer.

Talin-1 is one of the major scaffold proteins in focal adhesions playing a vital role in cell migration, metastasis, and cancer progression. Although studies regarding the importance of Talin-1 in cancer have rapidly developed, its prognostic and diagnostic value still remain unsatisfying in pancreatic cancer (PC). Therefore, the present study aims to investigate the expression, clinical significance, as well as the prognostic and diagnostic value of Talin-1 in different types of PC.

Discrepancy in PD-L1 expression between primary and metastatic tumors in two patients with recurrent cervical cancer.

Introduction: Pembrolizumab is an immunotherapy approved for use in patients with a combined positive score (CPS) greater than one with recurrent cervical cancer. In clinical practice, the CPS score is not typically analyzed in both primary and metastatic specimens.

Case Descriptions: Case 1A 42-year-old woman with history of an abnormal pap smears who presented with a large pelvic mass with initial biopsy of cervix demonstrating squamous cell carcinoma with negative PDL1 expression and a CPS score of 0.

Mentorship of Junior Surgical Faculty Across Academic Programs in Surgery.

Importance: Because mentorship is critical for professional development and career advancement, it is essential to examine the status of mentorship and identify challenges that junior surgical faculty (assistant and associate professors) face obtaining effective mentorship.

Objective: To evaluate the mentorship experience for junior surgical faculty and highlight areas for improvement.

Design, Setting, And Participants: This qualitative study was an explanatory sequential mixed-methods study including an anonymous survey on mentorship followed by semistructured interviews to expand on survey findings.

Socioeconomic disparities in kidney transplant access for patients with end-stage kidney disease within the All of Us Research Program.

Objectives: Disparity in kidney transplant access has been demonstrated by a disproportionately low rate of kidney transplantation in socioeconomically disadvantaged patients. However, the information is not from national representative populations with end-stage kidney disease (ESKD). We aim to examine whether socioeconomic disparity for kidney transplant access exists by utilizing data from the All of Us Research Program.

Posttraumatic Cutaneous Meningioma with a "Meningiolipoma" Pattern Presenting as a Nasal Bridge Mass.

Meningiomas are tumors originating from arachnoid meningothelial cells. Occasionally, meningiomas are identified outside the central nervous system, and are referred to as extracranial meningiomas (EMs). The vast majority of EMs are an extension from an intracranial or intraspinal tumor.

Successful application of eculizumab in typical haemolytic uraemic syndrome.

A woman in her 40s with no medical history presented on hospital day #0 with 3 days of epigastric pain, nausea, vomiting and bloody diarrhoea.
