Aversion to Mesh Use in Pelvic Floor Surgery in a Latina Population at the U.S.-Mexico Border.

IMPORTANCE: Limited studies have examined patient aversion to mesh use in pelvic surgery, especially in Latinas. OBJECTIVE: This study aimed to assess aversion to pelvic surgery with mesh for urinary incontinence and pelvic organ prolapse in a sample of Latinas on the U.S.-Mexico border. STUDY DESIGN: This was a cross-sectional study of self-identified Latinas with symptoms of pelvic floor disorders, recruited at their initial consultation visit at a single, academic urogynecology clinic. Participants completed a validated survey to assess perceptions of mesh use in pelvic surgery. Participants also completed questionnaires assessing the presence and severity of pelvic floor symptoms and level of acculturation. The primary outcome was aversion to mesh surgery, as indicated by a response of "yes" or "maybe" to the question "Based on what you already know, would you avoid surgery using mesh?" Descriptive analysis, univariate relative risk, and linear regression analysis were completed to identify characteristics associated with mesh avoidance. Significance was assessed and considered at P values <0.05. RESULTS: Ninety-six women were included. Only 6.3% had prior pelvic floor surgery using mesh. Sixty-six percent indicated that they would be likely to avoid pelvic surgery that uses mesh. Only 9.4% indicated that they obtained information regarding mesh directly from medical professionals. Levels of concern regarding the use of mesh varied widely (29.2% not worried, 19.1% somewhat worried, 16.9% very worried). Higher percentages of "more acculturated" participants indicated a desire to avoid mesh surgery (58.7% vs 27.3%, P < 0.05). CONCLUSIONS: In this Latina population, a majority of patients indicated an aversion to using mesh in pelvic surgery. Few patients obtained information regarding mesh directly from medical professionals, relying instead on nonmedical sources.

Complete Vision Loss after Laparoscopic Hysterectomy.

Postoperative vision loss (POVL) is a rare but devastating complication that has only recently been reported following laparoscopic surgery. We present the case of a 34-year-old gravida 6 para 4 female who experienced POVL following an uncomplicated laparoscopic hysterectomy. Operating time was 174 minutes, and EBL was 75 mL. After surgery, she complained of complete vision loss with no light perception. No cerebral hemorrhage or ischemia was detected on imaging. Funduscopic exam revealed no structural abnormalities. On postoperative day 7, she received an IV methylprednisolone taper. The following morning, she reported mild light perception. Later that night, she reported a partial return of visual acuity and was discharged home. At her 2-week postoperative visit, her vision had returned to baseline. POVL is an emergency and prompt evaluation should be initiated to optimize outcome.

Perceptions of Mesh Use for Pelvic Floor Surgery in Latinas: Face Validity of a Spanish Questionnaire.

OBJECTIVE: The aim of the study was to validate a Spanish-translated survey assessing patients' perceptions of mesh use in pelvic floor surgery. METHODS: An English-language survey evaluating perceptions of mesh use underwent a process of Spanish translation and validation, using a forward-backward translation validation protocol. Self-identified bilingual Latinas with symptoms of pelvic floor disorders were recruited to participate in cognitive interviews after completing the survey in English and Spanish. κ coefficient and Cronbach α were calculated for measurement of reliability and internal consistency in responses. A P value of 0.05 was considered statistically significant. RESULTS: A total of 30 women were randomized to complete the initial survey in either English or Spanish. Demographics for the 2 cohorts were similar. For the Spanish-translated survey overall, 86% described the questions as "somewhat easy" or "very easy" to understand, and 93% reported that it was "clear" or "very clear" that the survey aimed to investigate their thoughts regarding mesh use. Approximately 63% of the participants expressed confusion over the use of the Spanish medical term "cabestrillo," translated for "sling." There were no significant differences in the responses on cognitive interview between the 2 groups. Overall, the responses between English and Spanish versions of the survey demonstrated good reliability and internal consistency. CONCLUSIONS: This study demonstrated face validity of a Spanish-translated survey assessing perceptions of mesh use in pelvic surgery in a Latina population. Participants' feedback was crucial to optimizing the quality of the survey for future studies that will evaluate Spanish-speaking patients' views of mesh implants in pelvic reconstructive surgery.

Effects of medication intake in early pregnancy on the fetal fraction of cell-free DNA testing.

OBJECTIVES: To determine the association between medications intake in early pregnancy and variation in the fetal fraction (FF) in pregnant women undergoing cell-free DNA (cfDNA) testing. METHODS: We performed a retrospective cohort study of women (n = 1051) undergoing cfDNA testing at an academic center. The exposed group included women taking medications (n = 400; 38.1%), while the nonexposed group consisted of women taking no medications (n = 651; 61.9%). Our primary outcome was FF. We performed univariate and multivariate analyses as appropriate. RESULTS: The FFs were 8.8% (6.6-12.1), 8.7% (6.3-11.6), and 7.7% (5.1-9.3) among women taking 0, 1, and two or more medications, respectively (P < 0.01). Using multivariable linear mixed effects model, the mean FF was significantly lower among those taking two or more medications compared with the nonexposed group. FF was directly correlated with gestational age at the time of cfDNA testing and inversely correlated with maternal obesity. Exposure to metformin was associated with 1.8% (0.2-3.4) lower mean FF when compared with the nonexposed group (P = 0.02). Obesity and intake of two or more medications were associated with higher hazard ratio of having a low FF less than 4%. CONCLUSIONS: Exposure to metformin or two or more medications was associated with decreased FF, and obesity is associated with delay in achieving adequate FF percentage. These findings should be considered while counseling patients on test limitations.

Chemotherapy for Hodgkin's lymphoma in a patient receiving clozapine for treatment-resistant schizophrenia: use of the Mental Capacity Act 2005.

Treatment resistance occurs in approximately 30% of individuals with schizophrenia and is commonly treated with clozapine. Nodular sclerosing Hodgkin's lymphoma is a subtype of Hodgkin's lymphoma predominantly affecting those under 50 years of age. In this case report, an individual with treatment-resistant schizophrenia developed nodular sclerosing Hodgkin's lymphoma and is treated with concurrent clozapine and systemic chemotherapy. The aim of this case report is to act as guidance for clinicians and to outline the difficulties of treating individuals with psychiatric illness under the Mental Capacity Act 2005 when the proposed treatment could lead to high levels of morbidity and mortality.

Upregulation of a functional form of the beta4 integrin subunit in colorectal cancers correlates with c-Myc expression.

The integrin beta4 subunit has been shown to be involved in various aspects of cancer progression. The aim of the present work was to evaluate the expression of beta4 in primary colon cancers and to investigate the occurrence of a previously identified intestinal nonfunctional variant of beta4 (beta4ctd-) for adhesion to laminin. Immunodetection of beta4 using a panel of antibodies and RT-PCR analyses were performed on series of paired primary colon tumors and corresponding resection margins. The beta4 subunit was found to be significantly overexpressed in cancer specimens at both the protein and transcript levels. Surprisingly, beta4 levels of expression were closely correlated with those of the oncogene c-Myc in individual specimens. In vitro studies of c-Myc overexpression showed an upregulation of beta4 promoter activity. Finally, the beta4ctd- form was identified in the normal proliferative colonic cells but was found to be predominantly absent in colon cancer cells, both in situ and in vitro. We concluded that the beta4ctd- form is lost from colon cancer cells, while the level of the wild-type form of beta4, which is functional for adhesion to laminin, is increased in primary tumors in relation with the expression of c-Myc.

High-level activation by a duodenum-specific enhancer requires functional GATA binding sites.

The purine metabolic gene adenosine deaminase (ADA) is expressed at high levels in a well-defined spatiotemporal pattern in the villous epithelium of proximal small intestine. A duodenum-specific enhancer module responsible for this expression pattern has been identified in the second intron of the human ADA gene. It has previously been shown that binding of the factor PDX-1 is essential for function of this enhancer. The studies presented here examine the proposed roles of GATA factors in the enhancer. Site-directed mutagenesis of the enhancer's GATA binding sites crippled enhancer function in 10 lines of transgenic mice, with 9 of the lines demonstrating <1% of normal activity. Detailed studies along the longitudinal axis of mouse small intestine indicate that GATA-4 and GATA-5 mRNA levels display a reciprocal pattern, with low levels of GATA-6 throughout. Interestingly, gel shift studies with duodenal nuclear extracts showed binding only by GATA-4.
