Is hysterectomy a risk factor for urinary incontinence?

Background: Hysterectomy is the most common gynecological surgery performed. There are few studies evaluating hysterectomy as a risk factor for urinary incontinence. If hysterectomy is found to be a risk factor for developing urinary incontinence, women undergoing hysterectomy can be well informed prior to the procedure regarding the same. The objective of the present study was to study the prevalence of urinary incontinence in post-menopausal women and its relationship to hysterectomy. To evaluate the association of metabolic syndrome, to urinary incontinence.Methods: This study was a prospective cohort study done in Christian Medical College and Hospital, Vellore, Tamil Nadu between December 2016- December 2017. Postmenopausal women both with natural and surgical menopause, were enrolled into the study after an informed consent. The UDI-6 questionnaire was used to assess urinary incontinence. The categorical variables were presented using frequencies and percentages. The comparison of categorical variables was done using Fisher's exact test. The odds ratio and confidence interval were calculated for the prevalence. P value < 0.05 was considered to be statistically significant.Results: A total of 600 women were enrolled into the study with 300 women having attained natural menopause and 300 women with a surgical menopause. The prevalence of urinary incontinence among these post-menopausal women was 46.24%. The prevalence of urinary incontinence amongst the women with natural menopause was 47.3% and amongst the women with surgical menopause was 45% (p = 0.566). Women with metabolic syndrome suffered from urinary incontinence more than their counterparts without metabolic syndrome (55.8% vs. 36%, p <0.0001).Conclusions: The prevalence of urinary incontinence in the natural menopause and surgical menopause groups was similar, thus proving that hysterectomy is not a risk factor for developing urinary incontinence. However, metabolic syndrome was found to be associated with urinary incontinence.

Identification and Quantification of Tree Species in Open Mixed Forests using High Resolution QuickBird Satellite Imagery

Present study deals with identification and quantification of tree species within an open mixed forest in parts of Ranchi district Jharkhand, India using high resolution QuickBird satellite data using image processing and GIS techniques. A high resolution QuickBird satellite image was used for shadow enhancement and tree crown area extraction. The First Principal Component of QuickBird satellite images was employed to enhance the shadowed area and subsequently shadow and non-shadow area were classified using ISODATA. The satellite image was used for crown area extraction with standard deviation of NDVI value and the crowns were classified into five classes using Maximum Likelihood supervised algorithm. Result shows that barring few limitation, the high resolution QuickBird image provides rapid and accurate results in terms of identification and quantification of tree species in conjugation with field verification and attained 88% of classification accuracy. It reduces the time required for obtaining inventory data in open mixed forest. Results also showed that total 5,522 trees of various species were present in the study area and dominated by Shorea robusta (80.48%) followed by Ziziphus mauritiana (16.26%), unknown tree (1.81%), Ficus religiosa (0.98%) and Mangifera indica (0.47%). The demography patterns of the locals mainly tribal (89.9%) exhibited their direct as well as indirect dependency on mixed forests resources for their subsistence and livelihood. The study necessitate towards the effective implication of policies to raise the standard of living of tribal people in the region

Prevalence of voiding and defecatory dysfunction in postmenopausal women with pelvic organ prolapse: a prospective observational study

Background: Primary objective of this work was to study the prevalence of voiding and defecatory dysfunction in women with pelvic organ prolapse and correlate the stage and compartment of prolapse with voiding and defecatory dysfunction. The secondary objective was to correlate stage of prolapse with flow rate and post void residue and to study the voiding dysfunction in pelvic organ prolapse.Methods: A prospective observational cohort study in 120 post-menopausal women scheduled for vaginal hysterectomy pelvic floor repair. Short form of pelvic floor distress inventory (PFDI-20) and International prostate symptom questionnaire I-PSS score for Lower urinary tract symptoms (LUTS)was employed.Results: The prevalence of voiding dysfunction in this study was 78% and defecatory dysfunction was 77%. Higher stage of prolapse had significant correlation with voiding dysfunction. (P value was 0.028). Women with posterior compartment defect had more voiding dysfunction with the significant P value (p value was 0.04). Pre-operative voiding dysfunction resolved post operatively in 86%, the p<0.000 which was highly significant.Conclusions: Women with pelvic organ prolapse had high prevalence of voiding and defecatory dysfunction. Stages of prolapse have positive correlation with voiding dysfunction. Pre-operative voiding dysfunction resolved after vaginal hysterectomy and pelvic floor repair

Evaluation of uroprotective efficacy of amifostine against cyclophosphamide induced hemorrhagic cystitis

The role of amifostine in the prevention of cyclophosphamide-induced hemorrhagic cystitis (HC) was evaluated in the rat model. Urinary bladders from control rats that received no drugs (group I) were compared with those from rats receiving cyclophosphamide alone at a dose of 150 mg/kg (group II), and two other groups receiving amifostine at 100 mg/kg (group III) and 200 mg/kg (group IV), 15 min prior to cyclophosphamide. Bladders were assessed macroscopically and histologically at 24 h and after 7 days. All the animals that received cyclophosphamide alone developed severe HC. On the basis of the scores of macroscopic and histologic changes, animals that received amifostine showed excellent uroprotection. Only 2/6 rats in group III and 1/6 rats in group IV developed mild HC at 24 h. None of the rats in either of these groups showed any evidence of HC at 7 days. It is concluded that amifostine protects the urothelium against cyclophosphamide-induced HC

Anthropometric cut-offs to identify hyperglycemia in an Afro-Caribbean population: a cross-sectional population-based study from Barbados.

INTRODUCTION: Body mass index (BMI) and waist circumference (WC) cut-offs associated with hyperglycemia may differ by ethnicity. We investigated the optimal BMI and WC cut-offs for identifying hyperglycemia in the predominantly Afro-Caribbean population of Barbados. RESEARCH DESIGN AND METHODS: A cross-sectional study of 865 individuals aged ≥25 years without known diabetes or cardiovascular disease was conducted. Hyperglycemia was defined as fasting plasma glucose ≥5.6 mmol/L or hemoglobin A1c ≥5.7% (39 mmol/mol). The Youden index was used to identify the optimal cut-offs from the receiver operating characteristic (ROC) curves. Further ROC analysis and multivariable log binomial regression were used to compare standard and data-derived cut-offs. RESULTS: The prevalence of hyperglycemia was 58.9% (95% CI 54.7% to 63.0%). In women, optimal BMI and WC cut-offs (27 kg/m2 and 87 cm, respectively) performed similarly to standard cut-offs. In men, sensitivities of the optimal cut-offs of BMI ≥24 kg/m2 (72.0%) and WC ≥86 cm (74.0%) were higher than those for standard BMI and WC obesity cut-offs (30.0% and 25%-46%, respectively), although with lower specificity. Hyperglycemia was 70% higher in men above the data-derived WC cut-off (prevalence ratio 95% CI 1.2 to 2.3). CONCLUSIONS: While BMI and WC cut-offs in Afro-Caribbean women approximate international standards, our findings, consistent with other studies, suggest lowering cut-offs in men may be warranted to improve detection of hyperglycemia. Our findings do, however, require replication in a new data set.The project was supported by the Ministry of Health of the Government of Barbados.

Inducing remission of Type 2 diabetes in the Caribbean: findings from a mixed methods feasibility study of a low-calorie liquid diet-based intervention in Barbados.

AIM: In a high proportion of people with recently diagnosed Type 2 diabetes, a short (2-3-month) low-calorie diet is able to restore normal glucose and insulin metabolism. The aim of this study was to determine the feasibility of this approach in Barbados. METHODS: Twenty-five individuals with Type 2 diabetes diagnosed within past 6 years, not on insulin, BMI ≥ 27 kg/m2 were recruited. Hypoglycaemic medication was stopped on commencement of the 8-week liquid (760 calorie) diet. Insulin response was assessed in meal tests at baseline, 8 weeks and 8 months. Semi-structured interviews, analysed thematically, explored participants' experiences. 'Responders' were those with fasting plasma glucose (FPG) < 7 mmol/l at 8 weeks. RESULTS: Ten men and 15 women (mean age 48, range 26-68 years) participated. Mean (sd) BMI was 34.2 kg/m2 (6.0); FPG 9.2 mmol/l (2.2). Mean weight loss at 8 weeks and 8 months was 10.1 kg [95% confidence interval (CI) 8.1, 12.0] and 8.2 kg (95% CI 5.8, 10.6); FPG was lower by 2.2 mmol/l (95% CI 1.2, 3.2) and 1.7 mmol/l (95% CI 0.8, 2.7) respectively. Nine of 11 (82%) of those who lost ≥ 10 kg were 'responders' compared with 6 of 14 (43%) who lost < 10 kg (P = 0.048). The 30-min insulin increment was higher in responders at baseline and follow-up (P ≤ 0.01). A food culture based on starchy foods and pressures to eat large amounts at social events were among the challenges identified by participants. CONCLUSIONS: The feasibility of this approach to weight loss and diabetes remission in a predominantly black population in Barbados was demonstrated
