The impact of laparoscopic gynecological surgery training on the technicity index of a developing country center.

PURPOSE: To compare laparoscopic gynecological surgery training between a developed country's reference center (host center) and a public reference service in a developing country (home center), and use the technicity index (TI) to compare outcomes and to determine the impact of laparoscopic gynecological surgery fellowship training on the home center's TI. METHODS: The impact of training on the home center was assessed by comparing surgical performance before and after training. TI was assessed in 2017 in the host center, and before and after training in the home center. Epidemiological and clinical data, and information on reason for surgery, preoperative images, estimated intraoperative bleeding, operative time, surgical specimen weight, hospital stay length, complication and reintervention rates were collected from both institutions. Home center pre-training data were retrospectively collected between 2010 and 2013, while post-training data were prospectively collected between 2015 and 2017. A two-tail Z-score was used for TI comparison. RESULTS: The analysis included 366 hysterectomies performed at the host center in 2017, and 663 hysterectomies performed at the home center between 2015 and 2017. TI in the host center was 82.5%, while in the home center it was 6% before training and 22% after training. There were no statistical differences in length of hospital stay, preoperative uterine volume, surgical specimen weight and complication rate between centers. However, significantly shorter mean operative time and lower blood loss during surgery were observed in the host center. CONCLUSIONS: High-quality laparoscopic training in a world-renowned specialized center allowed standardizing laparoscopic hysterectomy procedures and helped to significantly improve TI in the recipient's center with comparable surgical outcomes.

Isolated vitamin D supplementation improves the adipokine profile of postmenopausal women: a randomized clinical trial.

OBJECTIVE: The aim of the study is to evaluate the effect of vitamin D supplementation alone on the adipokine profile of postmenopausal women. METHODS: In this randomized clinical trial, 160 women were randomized to 2 groups: oral supplementation with 1,000 IU cholecalciferol/d (vitamin D, n = 80) or placebo (PL, n = 80). Women with amenorrhea 12 months or more and aged 50 to 65 years were included. Women with established cardiovascular disease, insulin-dependent diabetes, renal failure, liver diseases, and previous use of menopausal hormone therapy and vitamin D were excluded. The intervention lasted 9 months and serum adiponectin, resistin, and adipsin levels were determined at the start and end of treatment. Intention to treat was adopted as the statistical method using a repeated measures design, followed by Wald's multiple comparison test adjusted for group × time interaction. RESULTS: After 9 months, 25-hydroxyvitamin D concentrations increased from 15.0 ± 7.5 to 27.5 ± 10.4 ng/mL (+45.4%) in the vitamin D group and decreased from 16.9 ± 6. to 13.8 ± 6.0 ng/mL (-18.5%) in the PL group ( P < 0.001). In the vitamin D group, there was an increase in adiponectin (+18.6%) and a decrease in resistin (-32.4%, P < 0.05). At the end point, a difference was observed between the PL and vitamin D groups in mean adiponectin and resistin levels (11.5 ± 5.5 vs 18.5 ± 21.8 ng/mL, P = 0.047, and 16.5 ± 3.5 vs 11.7 ± 3.3 ng/mL, P = 0.027, respectively). There were no significant intervention effects on serum adipsin levels. CONCLUSIONS: Daily supplementation with 1,000 IU of vitamin D alone was associated with an increase in adiponectin and a decrease in resistin, suggesting a beneficial effect on the adipokine profile of postmenopausal women with vitamin D deficiency.

Three-dimensional ultrasound evaluation of the pelvic floor in postmenopausal women using hormone therapy.

OBJECTIVE: To evaluate the three-dimensional (3D) ultrasound characteristics of the pelvic floor muscles (PFM) in two groups of postmenopausal women: users and nonusers of menopausal hormone therapy (MHT). STUDY DESIGN: Observational, cross-sectional cohort study. MAIN OUTCOME MEASURES: In this study 226 sexually active heterosexual women, aged 45-60 years with amenorrhea >12 months and without clinical pelvic floor disorders or urinary incontinence were included. Women using MHT ≥ 6 months were classified as systemic users. PFM strength was assessed by digital vaginal palpation and scored on the Modified Oxford Scale. Biometry of the PFM was performed by 3D transperineal ultrasound for evaluation of total urogenital hiatus area, transverse and anteroposterior diameters, and levator ani muscle thickness. RESULTS: The participants were divided into users (n = 78) and nonusers (n = 148) of MHT. There were no differences in clinical or anthropometric parameters between groups. The mean age was 55 years and the time since menopause was six years in both groups. The mean duration of MHT use was 43.4 ± 33.3 months. Users of MHT had greater levator ani muscle thickness (p = 0.001) and higher PFM strength (p = 0.029) than nonusers. Risk analysis adjusted for age, time since menopause, BMI, parity, and type of delivery showed an association of MHT use with greater levator ani muscle thickness (OR = 2.69; 95% CI 1.42-5.11, p = 0.029), and higher PFM strength (OR = 1.78; 95% CI1.01-3.29, p = 0.046). There was a weak positive correlation between levator ani muscle thickness and duration of MHT use (r = 0.25, p = 0.0002) and PFM strength (r = 0.12, p = 0.043). CONCLUSIONS: Postmenopausal women using MHT had a greater levator ani muscle thickness associated with higher PFM strength than nonusers.

The role of laparoscopy in the propaedeutics of gynecological diagnosis1.

PURPOSE: To evaluate agreement between pre- and post-laparoscopy gynecological diagnosis in order to demonstrate the rationality of this minimally invasive technique use in gynecological propaedeutics. METHODS: Retrospective chart review study conducted between March 2010 and October 2016 based on a convenience sample. 315 patients undergoing surgical laparoscopy at the Center of Gynecologic Endoscopy and Family Planning of Botucatu Medical School/UNESP. Pre- and postoperative diagnoses were compared by the diagnosis agreement test considering the proportions of events. RESULTS: Laparoscopy contributed to diagnosis in 59.6% of infertility cases (P>0.05), in 93.7% of chronic pelvic pain of undetermined origin (P<0.01) and conclusively elucidated the diagnosis of acute abdomen and the ruling out of tubo-ovarian abcess (P<0.05). Laparoscopy also increased the diagnosis of pelvic-abdominal adhesions in 76.7% (P>0.05). CONCLUSION: The use of laparoscopy considerably contributed to diagnostic elucidation, especially in cases of undetermined chronic pelvic pain.

Concomitant p53 and PTEN immunoexpression to predict the risk of malignancy in endometrial polyps.

The aim of this retrospective cross-sectional study was to assess the usefulness of phosphase and tensin homolog deleted on chromosome 10 (PTEN) and p53 protein immunoexpression in predicting the risk of malignancy in endometrial polyps. The study was conducted at tertiary public hospital, university teaching center, and private practice clinic.A total of 159 patients with endometrial polyps who underwent hysteroscopic polypectomy between January 2010 to December 2014 were included. p53 and PTEN immunoexpression were assessed in histologic endometrial polyp samples. Patients were allocated into 2 groups: group A, endometrial polyps without atypia (120), and group B, endometrial polyps with atypia (39), which were subdivided into A1 (80) and B1 (21) = p53-/PTEN+ immunostaining; A2 (20) and B2 (11) = p53+/PTEN+; A3 (14) and B3 (4) = p53+/PTEN-; A4 (6) and B4 (3) = p53-/PTEN-.There was no significant difference between groups regarding clinical and epidemiologic parameters, except for age. Neoplasia incidence within groups was higher when at least 1 marker was abnormally stained (in group A, P = .0089, odds ratio [OR] = 13.94 [1.62; 120.27]; in group B, P = .0255, OR 12.73 [1.38; 117.27]). Overall neoplasia incidence was higher in group B than in group A (20.5% vs 5.8%; P = .0113). Malignant neoplasia was found more frequently in patients with p53+ (P = .0006, OR = 7.67 [2.30; 25.54]) and PTEN- (P = .0043; OR = 5.43 [1.77; 16.61]).Immunohistochemical analysis using p53 and PTEN as markers, either alone or concomitantly, can be useful to predict malignant transformation in cases of endometrial polyps.

Immunohistochemical expression of hormone receptors, Ki-67, endoglin (CD105), claudins 3 and 4, MMP-2 and -9 in endometrial polyps and endometrial cancer type I.

OBJECTIVE: The aim of this study was to investigate the malignant potential of endometrial polyps (EP) by assessing the immunoexpressions of both estrogen receptor (ER) and progesterone receptor (PR), Ki-67 cell proliferation index, neovascularization network (endoglin - CD105), cellular adhesion molecules (claudins 3 and 4), and extracellular matrix proteins (MMP-2 and -9) in both EP and endometrioid adenocarcinoma (type I) in comparison with the normal endometrium. STUDY DESIGN: This is a cross-sectional comparative study. Patients were identified from the database of Botucatu Medical School, São Paulo State University (BMS-UNESP) Clinical Pathology Laboratory. SETTING: The study was conducted using a convenience sample of patients attending the Sectors of Gynecologic Endoscopy and Family Planning and Gynecologic Oncology of the Department of Gynecology and Obstetrics of BMS-UNESP, Brazil. PATIENTS: A total of 90 women were allocated into the following three groups: EP without atypia (EP, n=30), endometrioid endometrial cancer (EC, n=30), and normal endometrium (control, n=30). METHODS: Epidemiological and clinical data were obtained by reviewing medical records. Adenocarcinoma and control cases were assessed using the tissue microarray technique. The immunoexpressions of ER, PR, Ki-67, CD105, claudins 3 and 4, and MMP-2 and -9 were assessed in paraffin blocks containing sections of the largest polyploid lesion fragment and tissue microarray recipient blocks. MAJOR RESULTS: Compared to the control group, significant differences in the expression of ER (P<0.001), PR (P<0.05), Ki-67 (P<0.001), CD105 (P<0.001), and claudin 3 (P<0.001) were observed in EP and EC. No significant differences were found between EP and EC (P≥0.05). MMP-2 and -9 expression were nearly absent in all groups. CONCLUSION: The malignant potential of EP could not be determined through the immunohistochemical parameters used in this study. No MMP-2 or -9 expression was observed in any endometrial tissue sample. Further studies are necessary for a better understanding of the biomolecular mechanisms underlying endometrial carcinogenesis.

Isolated vitamin D supplementation improves the immune-inflammatory biomarkers in younger postmenopausal women: a randomized, double-blind, placebo-controlled trial.

OBJECTIVE: The aim of this study was to evaluate the effect of vitamin D (VitD) supplementation on immune-inflammatory biomarkers in younger postmenopausal women. METHODS: In this double-blind, placebo-controlled trial, 160 postmenopausal women aged 50 to 65 years with amenorrhea ≥12 months were randomized into two groups: VitD group, oral supplementation with 1000 IU VitD3/day (n = 80) or placebo group (n = 80). The intervention time was 9 months, and the women were assessed at baseline and endpoint. Serum levels of interleukins (ILs)-1ß, IL-5, IL-6, IL-10, IL-12ρ70, IL-17α, tumor necrosis factor-alpha, and interferon-gamma were determined by immunoassay. Plasma concentrations of 25-hydroxyvitamin D [25(OH)D] were measured by high-performance liquid chromatography. Per-protocol analysis was adopted as the statistical method using a gamma distribution and repeated measures design, followed by Wald's multiple comparisons test. RESULTS: The two groups were similar at baseline in terms of clinical and laboratory parameters. After 9 months, there was a significant increase of 25(OH)D levels in the VitD group (+45.4%, P < 0.001) and a decrease (-18.5%, P = 0.049) in the placebo group. A significant decrease in IL-5, IL-12p70, IL-17α, tumor necrosis factor-alpha, and interferon-gamma levels was observed in the VitD group (P < 0.05). IL-5 and IL-6 levels were significantly lower in the VitD group compared to the placebo group (P < 0.05). There were no significant intervention effects on serum IL-1ß or IL-10 levels in either group (P > 0.05). CONCLUSIONS: In younger postmenopausal women, isolated supplementation with 1000 IU of VitD3 for 9 months was associated with a reduction in proinflammatory biomarkers.

The value of hysteroscopic biopsy in the diagnosis of endometrial polyps.

Several studies have demonstrated that the combination of hysteroscopy with endometrial biopsy is more accurate in differentiating endometrial polyps from endometrial hyperplasia and cancer. However, blind biopsy not always confirms hysteroscopic findings due to high rates of inadequate or insufficient material. The objective of this clinical, prospective, and comparative study was to establish a correlation between the histological results of office-based endometrial biopsies (hysteroscopically guided and blind) with the surgical polypectomy specimens. We evaluated 82 patients with hysteroscopic diagnosis of endometrial polyp, who randomly underwent hysteroscopically guided biopsy or blind biopsy, referred for surgical resection. A total of 36 women (43.9%) underwent hysteroscopically guided biopsy and 46 women (56.1%) underwent blind biopsy. The sensitivity of hysteroscopically guided biopsy for the diagnosis of endometrial polyps ranged between 35.3 and 36.8%, when carried out at the apex and base of the lesion, compared with 29.2% for blind biopsy. Specificity was 33.3, 50, and 60%, respectively, for each biopsy. The positive predictive values were 75, 77.8, and 87.5%, and negative predictive values were 8.3, 14.3, and 8.1% respectively, compared with surgical polypectomy specimens. The office-based endometrial biopsies had low diagnostic accuracy for endometrial polyps compared with surgical polypectomy specimens.

Metabolic syndrome as a predictor of endometrial polyps in postmenopausal women.

OBJECTIVE: The aim of the study was to evaluate clinical predictive factors for endometrial polyps in postmenopausal women compared with postmenopausal women without polyps. METHODS: In this cross-sectional study, 132 Brazilian women with a histopathological diagnosis of endometrial polyps were compared with 264 women without endometrial alterations (control). The study group included women aged at least 45 years with amenorrhea for at least 12 months, who underwent hysteroscopic polypectomy. The control group consisted of women aged at least 45 years with amenorrhea for at least 12 months, without postmenopausal bleeding and endometrial thickness less than 5 mm by transvaginal ultrasonography. Clinical, anthropometric (body mass index and waist circumference), laboratory, and ultrasonographic data were collected to evaluate predictive factors for endometrial polyps. The Student's t test, χ test, and logistic regression (odds ratio [OR]) were used for statistical analysis. RESULTS: A higher percentage of women with polyps were obese (72%) when compared with control (39%) (P < 0.0001). Waist circumference was greater among women with polyps (P = 0.0001). The incidence of diabetes, hypertension, and dyslipidemia was higher among women with endometrial polyps (P < 0.0001). According to the diagnostic criteria of the US National Cholesterol Education Program/Adult Treatment Panel III (NCEP/ATP III), 48.5% of the women with polyps and 33.3% of the controls were classified as having metabolic syndrome (MetS) (P = 0.004). The risk of endometrial polyps was higher in women with body mass index at least 25 kg/m (OR = 4.66; 95% CI 2.16-10.05); glucose at least 100 mg/dL (OR = 2.83; 95% CI 1.36-5.90); dyslipidemia (OR = 7.02; 95% CI 3.70-13.32); diabetes (OR = 2.58; 95% CI 1.05-6.32); and MetS (OR = 2.76; 95% CI 1.18-6.46) when compared with control, adjusted for age, and time since menopause. CONCLUSIONS: In postmenopausal women, obesity, dyslipidemia, hyperglycemia, and the presence of MetS were predictive factors for endometrial polyps.

Transvaginal ultrasonography and hysteroscopy as predictors of endometrial polyps in postmenopause.

The study compared ultrasound and ambulatorial hysteroscopy as diagnostic methods detecting endometrial polyps in postmenopause women. 281 women aged 41-82 years who underwent ambulatorial hysteroscopy were analyzed for presence of uterine bleeding and/or altered transvaginal ultrasound (endometrial thickness ≥5 mm). Ultrasonography detected endometrial polyps in 22.8% of patients and endometrial thickening in the other 59.8%. Hysteroscopy diagnosed endometrial polyps in 80.8%. Ultrasonography showed sensitivity of 88.7%, specificity of 25.4%, positive predictive value of 81.7%, negative predictive value of 37.5% and accuracy of 75.4% in diagnosing endometrial polyps. Hysteroscopy showed 96.4% sensitivity, 74.6% specificity, 93.4% positive predictive value, 84.6% negative predictive value and 91.8% accuracy. Hysteroscopy demonstrated more accuracy than ultrasonography, which is not sufficient for accurate diagnosis.

[Predictive factors for occurrence of endometrial polyps in postmenopausal women.] / Fatores preditivos para a ocorrência de pólipos endometriais em mulheres na pós-menopausa.

PURPOSE: To evaluate the predictive clinical factors for the development of endometrial polyps in postmenopausal women. METHODS: Observational cohort study with postmenopausal women who had been at a public university hospital. Clinical, anthropometrical, laboratorial, and ultrasonographic data of 132 patients with a histopathological diagnosis of endometrial polyps and 264 women without endometrial alterations (control) were compared in order to evaluate the predictive factors of endometrial polyps. Women with amenorrhea ≥12 months and ≥45 years of age were included in the study at a proportion of 1 case for 2 controls. The Student's t, χ2, and logistic regression tests were used for statistical analysis - odds ratio (OR). RESULTS: Patients with endometrial polyps were older and had been in menopause for a longer time compared to control (p<0.0001). The percentage of obese women with polyps (72.0%) was higher compared to the Control Group (39%; p<0.0001). The measurement of waist circumference was superior among patients with polyps (p=0.0001). We observed a higher incidence of diabetes, hypertension and dyslipidemia in patients with endometrial polyps (p<0.0001). According to the US National Cholesterol Education Program/Adult Treatment Panel III (NCEP/ATP III) criteria, 48.5% of women with polyps and 33.3% of the Control Group were classified as having metabolic syndrome (p=0.004). Analysis of risk for endometrial polyps formation showed higher chances of occurrence of the disorder in patients with: BMI≥25 kg/m2 (OR=4.6; 95%CI 2.1-10.0); glucose ≥100 mg/dL (OR=2.8; 95%CI 1.3-5.9); dyslipidemia (OR=7.0; 95%CI 3.7-13.3); diabetes (OR=2.5; 95%CI 1.0-6.3), and metabolic syndrome (OR=2.7; 95%CI 1.1-6.4) compared to the Control Group. CONCLUSION: In postmenopausal women, obesity, dyslipidemia, hyperglycemia and presence of metabolic syndrome were predictive factors for the development of endometrial polyps.
