Educational Value of Surgical Residents Operating as Teaching Assistant.

Objective: To assess the educational of value of teaching assistant (TA) cases from the perspectives of attending, chief resident, and junior resident. We hypothesized the greatest educational value of TA cases would be for chief residents more so than other team members.

Design: A prospective survey was designed and collected for TA cases separately from attendings, chief residents, and junior residents to assess operative details and educational value.

Barriers and facilitators to diabetes screening and prevention after a pregnancy complicated by gestational diabetes.

Objective: Gestational diabetes mellitus (GDM) is increasing in the United States, with higher rates among minoritized racial and ethnic populations and lower income populations. GDM increases risk for type 2 diabetes (T2DM), and postpartum diabetes screening and prevention are imperative. This qualitative study examines barriers and facilitators to postpartum T2DM screening and prevention among non-privately insured individuals with a history of GDM in a state prior to Medicaid expansion.

Strategies to Achieve Breast Health Equity in the St. Louis Region and Beyond over 15+ Years.

Community-based participatory strategies are a promising approach to addressing disparities in community health outcomes. This paper details the efforts of Siteman Cancer Center to achieve breast health equity over the past 15+ years. We begin by describing the activities and successes arising from our breast health community partnerships including identifying priorities, developing recommendations, and implementing patient navigation services to advance breast health.

Understanding Gestational Diabetes, Future Diabetes Risk, and Diabetes Prevention: A Qualitative Study of Patient, Provider, and Staff Perspectives.

Gestational diabetes mellitus (GDM) increases type 2 diabetes risk; however, postpartum diabetes screening rates are low. Using semi-structured interviews and focus groups, this study investigates the understanding of GDM and its relationship to future diabetes risk and diabetes prevention among patients with public or no insurance ( = 36), health care providers ( = 21), and clinic staff ( = 9) from Federally Qualified Health Centers. Five main themes emerged: ) general understanding of GDM diagnosis with focus on neonatal complications; ) variable recall of diet, exercise, and weight recommendations; ) overwhelming medication and self-monitoring routines; ) short-term focus of type 2 diabetes risk and screening; and ) limited understanding of all options for diabetes prevention.

Evaluating Birth Outcomes From a Community-Based Pregnancy Support Program for Refugee Women in Georgia.

Refugee women face numerous and unique barriers to sexual and reproductive healthcare and can experience worse pregnancy-related outcomes compared with U.S.-born and other immigrant women.

Objective: To differentially diagnose two calcified objects found with the well-preserved and nearly complete skeletal remains excavated in June 2012 by the Haáz Rezső Múzeum in Odorheiu Secuiesc, Romania.

Material: Two objects measuring 25.55 × 18.

Evaluation of anterior versus posterior component separation for hernia repair in a cadaveric model.

Background: Component separation remains an integral step during ventral hernia repair. Although a multitude of techniques are described, anterior component separation (ACS) via external oblique release (EOR) and posterior component separation (PCS) via transversus abdominis muscle release (TAR) are commonly utilized. The extent of myofascial medialization after ACS or PCS has not been well elucidated.

Laparoscopic ventral hernia repair with and without defect closure: comparative analysis of a single-institution experience with 783 patients.

Background: Laparoscopic ventral hernia repair (LVHR) has gained popularity, since it can decrease the incidence of surgical site complications while providing similar recurrence rates as open repairs. The role of defect closure in LVHR has been a subject of controversy and has not been fully elucidated. We aimed to compare outcomes of LVHR with and without defect closure in a contemporary cohort.

Health care worker perceptions toward computerized clinical decision support tools for Clostridium difficile infection reduction: A qualitative study at 2 hospitals.

Background: Clostridium difficile infection (CDI) is associated with significant morbidity and mortality. Computerized clinical decision support (CCDS) tools can aid process improvement in infection prevention and antibiotic stewardship, but implementation and health care workers (HCWs) uptake of these tools is often variable. The objective of this study was to describe HCWs' perceptions of barriers and facilitators related to uptake of CCDS tools as part of a CDI reduction bundle.

Inguinal Hernia: Mastering the Anatomy.

The success of an inguinal hernia repair is defined by the permanence of the operation while creating the fewest complications at minimal cost and allowing patients an early return to activity. This success relies and depends on the surgeon's knowledge and understanding of groin anatomy and physiology. This article reviews relevant anatomy to inguinal hernia repair and technical steps to open tissue and mesh repairs as well as minimally invasive approaches.

Silicone Hydrogel and Rigid Gas-Permeable Scleral Lens Tear Exchange.

Objectives: To quantify tear elimination rate (ER) underneath silicone hydrogel (Si-Hy) and scleral gas permeable (GP) contact lenses (CLs).

Methods: Subjects successfully using either well-fitting soft Si-Hy CLs or scleral GP CLs were recruited. Most scleral GP CL wearers had irregular corneas (e.

Stapled Transabdominal Ostomy Reinforcement with retromuscular mesh (STORRM): Technical details and early outcomes of a novel approach for retromuscular repair of parastomal hernias.

Background: Parastomal hernia repair (PHR) remains a challenge with no optimal repair technique. During retromuscular hernia repair, traversing the stomal conduit through the abdominal wall can result in angulation and compression. Widening of traditional cruciate incisions in mesh and/or fascia likely contributes to recurrences.

Hematopoietic-to-mesenchymal transition of adipose tissue macrophages is regulated by integrin β1 and fabricated fibrin matrices.

Some bona fide adult adipocytes arise de novo from a bone marrow-derived myeloid lineage. These studies further demonstrate that adipose tissue stroma contains a resident population of myeloid cells capable of adipocyte and multilineage mesenchymal differentiation. These resident myeloid cells lack hematopoietic markers and express mesenchymal and progenitor cell markers.

Evaluation of antibiotic pressurized pulse lavage for contaminated retromuscular abdominal wall reconstruction.

Background: Despite patient risk factors such as diabetes and obesity, contamination during surgery remains a significant cause of infections and subsequent wound morbidity. Pressurized pulse lavage (PPL) has been utilized as a method to reduce bacterial bioburden with promising results in many fields. Although existing methods of lavage have been utilized during abdominal operations, no studies have examined the use of PPL during complex hernia repair.

POEM is a cost-effective procedure: cost-utility analysis of endoscopic and surgical treatment options in the management of achalasia.

Background: Achalasia is a rare motility disorder of the esophagus. Treatment is palliative with the goal of symptom remission and slowing the progression of the disease. Treatment options include per oral endoscopic myotomy (POEM), laparoscopic Heller myotomy (LM) and endoscopic treatments such as pneumatic dilation (PD) and botulinum toxin type A injections (BI).

De novo generation of adipocytes from circulating progenitor cells in mouse and human adipose tissue.

White adipocytes in adults are typically derived from tissue resident mesenchymal progenitors. The recent identification of de novo production of adipocytes from bone marrow progenitor-derived cells in mice challenges this paradigm and indicates an alternative lineage specification that adipocytes exist. We hypothesized that alternative lineage specification of white adipocytes is also present in human adipose tissue.

Analysis and isolation of adipocytes by flow cytometry.

Analysis and isolation of adipocytes via flow cytometry is particularly useful to study their biology. However, the adoption of this technology has often been hampered by the presence of stromal/vascular cells in adipocyte fractions prepared from collagenase-digested adipose tissue. Here, we describe a multistep staining method and gating strategy that effectively excludes stromal contaminants.

Adipose lineage specification of bone marrow-derived myeloid cells.

We have reported the production of white adipocytes in adipose tissue from hematopoietic progenitors arising from bone marrow. However, technical challenges have hindered detection of this adipocyte population by certain other laboratories. These disparate results highlight the need for sensitive and definitive techniques to identify bone marrow progenitor (BMP)-derived adipocytes.

An inter-rater reliability study for the rorschach performance assessment system.

Based on available research findings, the Rorschach performance assessment system (Meyer, Viglione, Mihura, Erard, & Erdberg, 2011 ) was recently developed in an attempt to ground the administration, coding, and interpretation of the Rorschach in its evidence base, improve its normative foundation, integrate international findings, reduce examiner variability, and increase utility. This study sought to establish inter-rater reliability for the coding decisions in this new system. We randomly selected 50 Rorschach records from ongoing research projects using R-Optimized administration.

In combination, nucleoside reverse transcriptase inhibitors have significant effects on 3T3-L1 adipocyte lipid accumulation and survival.

The use of nucleoside reverse transcriptase inhibitors (NRTIs) for the treatment of HIV infection is clearly linked to the development of subcutaneous fat atrophy. Until recently, however, in vitro studies of adipocytes have shown no or only modest and inconsistent effects of these agents on adipocyte biology. This is in contrast to the protease inhibitors (PIs), which are also linked to the development of HIV lipodystrophy.

Biomorphometric analysis of human prostatic carcinoma by using three-dimensional computer models.

Advances in the detection of carcinoma of the prostate during the last 15 years have accounted for a sharp increase and then an abrupt decrease in the incidence of the disease. A more recent decline in its mortality rates has been variously interpreted as either the success of early detection and improved treatment or lead-time bias. The recently reported Prostate Cancer Prevention Trial had an overall detection rate that approached the 30%-40% prevalence rates reported in autopsy series in which men died of other causes.

Aberrant HOXC expression accompanies the malignant phenotype in human prostate.

Dysregulation of HOX gene expression has been implicated as a factor in malignancies for a number of years. However, no consensus has emerged regarding specific causative genes. Using a degenerate reverse transcription-PCR technique, we show up-regulation of genes from the HOXC cluster in malignant prostate cell lines and lymph node metastases.

Molecular characterization of human prostate carcinoma cell lines.

Background: This study presents a comprehensive survey and characterization of available prostate carcinoma cell lines, most of which have been widely used but are incompletely characterized.

Methods: A total of 21 cell lines were investigated, including three "classical" (DU 145, LNCaP, and PC-3) and 18 "non-classical" lines (1013L, 22Rv1, ALVA-55, ALVA-101, ARCaP, CWR-R1, DuCaP, DuPro-1, LAPC-4, MDA PCa 1, MDA PCa 2a, MDA PCa 2b, NCI-H660, PC-346C, PC-93, PSK-1, UM-SCP-1, and VCaP). Cytogenetics, DNA profiling, expression of basal, luminal, and neuroendocrine differentiation markers, and mutation analyses of the TP53 and androgen receptor (AR) genes were performed.
