Stress urinary incontinence surgery trends in academic female pelvic medicine and reconstructive surgery urology practice in the setting of the food and drug administration public health notifications.

AIMS: To investigate the possible effects of the Food and Drug Administration (FDA) Public Health Notifications in 2008 and 2011 regarding surgical trends in transvaginal mesh (TVM) placement for stress urinary incontinence (SUI) and related mesh revision surgery in Female Pelvic Medicine & Reconstructive Surgery (FPMRS) practice in tertiary care academic medical centers in the United States. METHODS: Surgical volume for procedures performed primarily by FPMRS surgeons at eight academic institutions across the US was collected using Current Procedural Terminology (CPT) codes for stress urinary incontinence repair and revision surgeries from 2007 to 2013. SAS statistical software was used to assess for trends in the data. RESULTS: There was a decrease in the use of synthetic mesh sling for the treatment of SUI at academic tertiary care centers over the past 7 years; however, this was not statistically significant. While the total number of surgical interventions for SUI remained stable, there was an increase in the utilization of autologous fascia pubovaginal slings (AFPVS). The number of mesh sling revision surgeries, including urethrolysis and removal or revision of slings, increased almost three-fold at these centers. CONCLUSIONS: These observed trends suggest a possible effect of the FDA Public Health Notifications regarding TVM on surgical practice for SUI in academic centers, even though they did not specifically warn against the use of synthetic mesh for this indication. Indications for surgery, complications, and outcomes were not evaluated during this retrospective study. However, such data may provide alternative insights into reasons for the observed trends.

Ethical Considerations for Surgical Planners from the Lessons Learned on USNS COMFORT (T-AH 20) Deployment 2019.

Ethical issues can arise when planning for direct patient care surgical missions. Based on the lessons learned from the USNS COMFORT Deployment 2019, the authors present concise considerations and recommendations for future hospital ship surgical mission planning.

Pelvic Organ Prolapse Surgery in Academic Female Pelvic Medicine and Reconstructive Surgery Urology Practice in the Setting of the Food and Drug Administration Public Health Notifications.

OBJECTIVE: To understand the effect of the Food and Drug Administration (FDA) public health notifications regarding transvaginal placement of surgical mesh for pelvic organ prolapsed (POP) on surgeon practice patterns in tertiary care academic medical centers. MATERIALS AND METHODS: Surgical volume for procedures performed primarily by fellowship trained Female Pelvic Medicine and Reconstructive Surgery at a sampling of 8 academic institutions across the US were collected using current procedural technology codes for POP repair and revision surgeries from 2007 to 2013. SAS statistical software was used to analyze data for trends and to assess differences in number of procedures across years by performing Spearman correlation analysis and Pearson's chi-squared test. Significance of trend was defined as P <.05 for both analysis methods. RESULTS: There has been a substantial reduction in transvaginal mesh-augmented repair of POP since the FDA warning statements of 2008 and 2011. Mesh revision surgery has increased over this same period. However, the total number of interventions for POP has remained stable over the study period. Abdominal sacrocolpopexy has increased as a whole but represents only a small percentage of total cases. CONCLUSION: Surgical correction of POP comprises a large portion of Female Pelvic Medicine and Reconstructive Surgery practice that continues to evolve in the aftermath of the FDA public health notifications. The utilization of transvaginal placement of surgical mesh augmented POP repair has decreased among practicing urologists at a sampling of academic institutions across the United States. Indications for surgery, complications, and outcomes were not evaluated during this retrospective study; however, such data may provide alternative insights into the reasons for the observed trends.

Induction of apoptosis and immune response by all-trans retinoic acid plus interferon-gamma in human malignant glioblastoma T98G and U87MG cells.

Glioblastoma is the most common and highly malignant brain tumor. It is also one among the most therapy-resistant human neoplasias. Patients die within a year of diagnosis despite the use of available treatment strategies such as surgery, radiotherapy, and chemotherapy. Thus, there is a critical need to find a novel therapeutic strategy for treating this disease. Here, we have investigated the molecular mechanisms for induction of apoptosis as well as for activation of immune components in human malignant glioblastoma T98G and U87MG cells following treatment with all-trans retinoic acid (ATRA) plus interferon-gamma (IFN-gamma). Treatment of glioblastoma cells with ATRA alone prevented cell proliferation and induced astrocytic differentiation, while IFN-gamma alone induced apoptosis and modulated expression of human leukocyte antigen (HLA) class II molecules such as HLA-DRalpha, HLA-DR complex, invariant chain (Ii), HLA-DM (an important catalyst of the class II-peptide loading), and gamma interferon-inducible lysosomal thiol-reductase (GILT). Interestingly, both T98G and U87MG cells showed more increase in apoptosis with expression of the HLA class II components for an effective immune response following treatment with ATRA plus IFN-gamma than with IFN-gamma alone. Apoptotic mode of cell death was confirmed morphologically by Wright staining and biochemically by measuring an increase in caspase-3 activity. While conversion of tumor cells into HLA class II+/Ii- cells by stimulation with the helper CD4+ T cells is thought to be challenging, this study reports for the first time that treatment of glioblastoma cells with ATRA plus IFN-gamma can simultaneously enhance apoptosis and expression of the HLA class II immune components with a marked suppression of Ii expression. Taken together, this study suggests that induction of apoptosis and immune components of the HLA class II pathway by ATRA plus IFN-gamma may be a promising chemoimmunotherapeutic strategy for treatment of human malignant glioblastoma.
