To assess the relationship between surgical delay and mortality in elderly patients with hip fracture. Systematic review and meta-analysis of retrospective and prospective studies published from 1948 to 2011. Medline (from 1948), Embase (from 1974) and CINAHL (from 1982), and the Cochrane Library. Odds ratios (OR) and 95% confidence intervals for each study were extracted and pooled with a random effects model. Heterogeneity, publication bias, Bayesian analysis, and meta-regression analyses were done. Criteria for inclusion were retro- and prospective elderly population studies, patients with operated hip fractures, indication of timing of surgery and survival status. There were 35 independent studies, with 191,873 participants and 34,448 deaths. The majority considered a cut-off between 24 and 48 hours. Early hip surgery was associated with a lower risk of death (pooled odds ratio (OR) 0.74, 95% confidence interval (CI) 0.67 to 0.81; P<0.000) and pressure sores (0.48, 95% CI 0.38 to 0.60; P<0.000). Meta-analysis of the adjusted prospective studies gave similar results. The Bayesian probability predicted that about 20% of future studies might find that early surgery is not beneficial for decreasing mortality. None of the confounders (e.g. age, sex, data source, baseline risk, cut-off points, study location, quality and year) explained the differences between studies. Surgical delay is associated with a significant increase in the risk of death and pressure sores. Conservative timing strategies should be avoided. Orthopaedic surgery services should ensure the majority of patients are operated within one or two days.

Background: Although lifestyle factors have been studied in relation to individual non-communicable diseases (NCDs), their association with development of a subsequent NCD, defined as multimorbidity, has been scarcely investigated. The aim of this study was to investigate associations between five lifestyle factors and incident multimorbidity of cancer and cardiometabolic diseases. Methods: In this prospective cohort study, 291,778 participants (64% women) from seven European countries, mostly aged 43 to 58 years and free of cancer, cardiovascular disease (CVD), and type 2 diabetes (T2D) at recruitment, were included. Incident multimorbidity of cancer and cardiometabolic diseases was defined as developing subsequently two diseases including first cancer at any site, CVD, and T2D in an individual. Multi-state modelling based on Cox regression was used to compute hazard ratios (HR) and 95% confidence intervals (95% CI) of developing cancer, CVD, or T2D, and subsequent transitions to multimorbidity, in relation to body mass index (BMI), smoking status, alcohol intake, physical activity, adherence to the Mediterranean diet, and their combination as a healthy lifestyle index (HLI) score. Cumulative incidence functions (CIFs) were estimated to compute 10-year absolute risks for transitions from healthy to cancer at any site, CVD (both fatal and non-fatal), or T2D, and to subsequent multimorbidity after each of the three NCDs. Results: During a median follow-up of 11 years, 1910 men and 1334 women developed multimorbidity of cancer and cardiometabolic diseases. A higher HLI, reflecting healthy lifestyles, was strongly inversely associated with multimorbidity, with hazard ratios per 3-unit increment of 0.75 (95% CI, 0.71 to 0.81), 0.84 (0.79 to 0.90), and 0.82 (0.77 to 0.88) after cancer, CVD, and T2D, respectively. After T2D, the 10-year absolute risks of multimorbidity were 40% and 25% for men and women, respectively, with unhealthy lifestyle, and 30% and 18% for men and women with healthy lifestyles. Conclusion: Pre-diagnostic healthy lifestyle behaviours were strongly inversely associated with the risk of cancer and cardiometabolic diseases, and with the prognosis of these diseases by reducing risk of multimorbidity.

Epidemiologic research in female sexual dysfunction (FSD) has gained momentum in recent years, particularly in clinical populations and in menopausal women. However, sexual dysfunction also affects premenopausal women in general populations. Previous literature reviews have been unable to quantify the burden of FSD in general populations. This has been due in part to different definitions of dysfunction, heterogeneous study design, and the wide variety of measurement tools used. To provide a meta-analytical estimate of the prevalence of FSD in premenopausal women. Observational studies that assessed the prevalence of FSD in premenopausal women were systematically sought in relevant databases (January 2000 through July 2014). Publications that reported the prevalence rate for at least one domain of FSD were included. A meta-analysis of prevalence rates was performed and a meta-regression was used to analyze factors of study design. Estimated prevalence rates of FSD and its domains (hypoactive sexual desire disorder, sexual aversion disorder, female sexual arousal disorder, lubrication difficulties, female orgasmic disorder, and pain disorders). After screening 9,292 results, 440 publications were retrieved for full-text review. Of these, 135 studies were included in the systematic review. Ninety-five of these studies were assessed further in a meta-analysis. There was substantial heterogeneity among studies. The prevalence of FSD in premenopausal women was estimated to be 40.9% (95% CI = 37.1-44.7, I2 = 99.0%). Prevalence rates of individual sexual disorders ranged from 20.6% (lubrication difficulties) to 28.2% (hypoactive sexual desire disorder). Further analyses showed significantly higher rates of FSD in studies in Africa, studies that used non-validated assessment tools, and studies without pharmaceutical funding. Prevalence estimates of FSD vary substantially. Nonetheless, results show that FSD is a significant public health problem that affects 41% of premenopausal women around the globe. More research and improved standardization are needed in this field.

Patients who undergo radical cystectomy for urothelial cancer are at risk for upper urinary tract disease in the remnant transitional tissue. Previous studies have identified several risk factors for upper urinary tract recurrence but the predictive value of each factor remains controversial. Furthermore, the schedule for surveillance of the upper urinary tract with imaging techniques and cytology has not been established. International guidelines do not address these topics and refer only to isolated works with a large case based analysis. We performed this meta-analysis to evaluate the effective incidence of upper urinary tract recurrence after cystectomy for bladder cancer, to analyze the risk factors so we can create subgroups of patients at high risk for recurrence and to investigate the real role of screening in the detection of upper tract lesions at an early stage. A bibliographic search covering the period from January 1970 to July 2010 was conducted using PubMed®, MEDLINE and EMBASE®. This analysis is based on the 27 studies that fulfilled the predefined inclusion criteria. Data were analyzed using a fixed effect logistic regression approach and classic meta-analysis. A total of 13,185 participants were included in the analysis. Followup was described in 22 studies and ranged from 0.36 to 349.2 months. The overall prevalence of upper tract transitional cell cancer after cystectomy ranged from 0.75% to 6.4%. Recurrence appeared at a range of 2.4 to 164 months, and in an advanced (64.6%) or metastatic state (35.6%) as reflected in poor survival rates. Patients with low grade vs high grade lesions at cystectomy showed as strong a significant difference in incidence as those with carcinoma in situ and superficial cancer vs invasive cancers and as strong as in those without lymph node involvement, with multifocal disease, with a history of multiple urothelial recurrences, with positive ureteral margins, with positive urethral margins, with urethral involvement and a history of upper urinary tract urothelial cancer. Data do not support a statistically significant difference in recurrence among patients with a history of carcinoma in situ, solitary lesion and among various types of urinary diversion adopted. In 24 studies the followup schedule included periodic radiological assessment of the upper urinary tract and in 20 it included urinary cytology. In 14 studies in 63 of 166 patients (38%) upper urinary tract recurrence was diagnosed by followup investigation whereas in the remaining 62% diagnosis was based on symptoms. When urine cytology was used in surveillance the rate of primary detection was 7% and with upper urinary tract imaging it was 29.6%. Of 5,537 patients who underwent routine cytological examination, recurrence was diagnosed in 1.8/1,000 and of those who underwent upper urinary tract imaging recurrence was diagnosed in 7.6/1,000. The recurrence values could appear low when considering the pan-urothelial field defect theory, but these values reflect, in part, the mortality associated with the initial bladder cancer. Based on anamnesis and pathological examination of cystectomy specimens, a group of patients is at high risk. Extensive regular followup with cytology, urography and loopgraphy yields insufficient benefits. Periodic computerized tomography with urography combines the ability to study the upper urinary tract oncologically and functionally, and the identification of any parenchymal, osseous or lymph node secondary lesion.

Sedentary behavior is related to increased mortality risk. Whether such elevated risk can be offset by enhanced physical activity has not been examined using accelerometry data. We examined the relations of sedentary time and physical activity to mortality from any cause using accelerometry data among 1,677 women and men aged 50 years or older from the National Health and Nutrition Examination Survey (NHANES) 2003–2004 cycle with follow-up through December 31, 2006. During an average follow-up of 34.67 months and 4,845.42 person-years, 112 deaths occurred. In multivariate Cox proportional hazard models, greater sedentary time (≥ median of 8.60 hours/day) was associated with increased risk of mortality from any cause (relative risk (RR) = 2.03; 95% confidence interval (CI) = 1.09-3.81). Low level of moderate to vigorous physical activity (< median of 6.60 minutes/day) was also related to enhanced all-cause mortality risk (RR = 3.30; 95% CI = 1.33-8.17). In combined analyses, greater time spent sedentary and low levels of moderate to vigorous physical activity predicted a substantially elevated all-cause mortality risk. As compared with the combination of a low sedentary level and a high level of moderate to vigorous physical activity, the risks of mortality from all causes were 4.38 (95% CI = 1.26-15.16) for low levels of both sedentary time and physical activity, 2.79 (95% CI = 0.77-10.12) for greater time spent sedentary and high physical activity level, and 7.79 (95% CI = 2.26-26.82) for greater time spent sedentary and low physical activity level. The interaction term between sedentary time and moderate to vigorous physical activity was not statistically significant (p = 0.508). Both high levels of sedentary time and low levels of moderate to vigorous physical activity are strong and independent predictors of early death from any cause. Whether a high physical activity level removes the increased risk of all-cause mortality related to sedentariness requires further investigation.
