Health-related Quality of life in 640 head and neck cancer survivors after radiotherapy using EORTC QLQ-C30 and QLQ-H&N35 questionnaires

<p>Abstract</p> <p>Background</p> <p>With the advances in modern radiotherapy (RT), many patients with head and neck cancer (HNC) can be effectively cured, and their health-related quality of life (HR-QoL) has become an important issue. In this study, we evaluated the prognosticators of HR-QoL in a large cohort of HNC patients, with a focus on the result from technological advances in RT.</p> <p>Methods</p> <p>A cross-sectional investigation was conducted to assess the HR-QoL of 640 HNC patients with cancer-free survival of more than 2 years. Among them, 371 patients were treated by two-dimensional RT (2DRT), 127 by three-dimensional conformal RT (3DCRT), and 142 by intensity-modulated RT (IMRT). The EORTC QLQ-C30 questionnaire and QLQ-H&N35 module were used. A general linear model multivariate analysis of variance was used to analyze the prognosticators of HR-QoL.</p> <p>Results</p> <p>By multivariate analysis, the variables of gender, annual family income, tumor site, AJCC stage, treatment methods, and RT technique were prognosticators for QLQ-C30 results, so were tumor site and RT technique for H&N35. Significant difference (<it>p </it>< 0.05) of HR-QoL outcome by different RT techniques was observed at 2 of the 15 scales in QLQ-C30 and 10 of the 13 scales in H&N35. Compared with 2DRT, IMRT had significant better outcome in the scales of global QoL, physical functioning, swallowing, senses (taste/smell), speech, social eating, social contact, teeth, opening mouth, dry mouth, sticky saliva, and feeling ill.</p> <p>Conclusions</p> <p>The technological advance of RT substantially improves the head-and-neck related symptoms and broad aspects of HR-QoL for HNC survivors.</p

Preventing renal and cardiovascular risk by renal function assessment: Insights from a cross-sectional study in low-income countries and the USA

Objective: To assess the prevalence of microalbuminuria and kidney dysfunction in lowincome countries and in the USA. Design: Cross-sectional study of screening programmes in five countries. Setting: Screening programmes in Nepal, Bolivia, the USA (National Health and Nutrition Examination Survey (NHANES) 2005-2008) Bangladesh and Georgia. Participants: General population in Nepal (n=20 811), Bolivia (n=3436) and in the USA (n=4299) and highrisk subjects in Bangladesh (n=1518) and Georgia (n=1549). Primary and secondary outcome measures: Estimated glomerular filtration rate (eGFR)<60ml/min/1.73 m 2 and microalbuminuria (defined as urinary albumin creatinine ratio values of 30-300 mg/g) were the main outcome measures. The cardiovascular (CV) risk was also evaluated on the basis of demographic, clinical and blood data. Results: The prevalence of eGFR<60ml/min/1.73 m2 was 19%, 3.2% and 7% in Nepal, Bolivia and the USA, respectively. In Nepal, 7% of subjects were microalbuminuric compared to 8.6% in the USA. The prevalence of participants with predicted 10-year CV disease (CVD) risk 6510% was 16.9%, 9.4% and 17% in Nepal, Bolivia and in the USA, respectively. In Bangladesh and Georgia, subjects with eGFR<60 ml/min/1.73 m2 were 8.6% and 4.9%, whereas those with microalbuminuria were 45.4% and 56.5%, respectively. Predicted 10-year CVD risk 6510% was 25.4% and 25% in Bangladesh and Georgia, respectively. Conclusions: Renal abnormalities are common among low-income countries and in the USA. Prevention programmes, particularly focused on those with renal abnormalities, should be established worldwide to prevent CVD and progression to end-stage renal disease

Effect of Tamsulosin on Stone Passage for Ureteral Stones: A Systematic Review and Meta-analysis

Study objectiveTamsulosin is recommended for patients receiving a diagnosis of a ureteral stone less than 10 mm who do not require immediate urologic intervention. Because of conflicting results from recent meta-analyses and large randomized controlled trials, the efficacy of tamsulosin is unclear. We perform a systematic review and meta-analysis to investigate the effect of tamsulosin on stone passage in patients receiving a diagnosis of ureteral stone.MethodsMEDLINE, EMBASE, and CENTRAL databases were searched without language restriction through November 2015 for studies assessing the efficacy of tamsulosin and using a double-blind, randomized, controlled trial design. Meta-analysis was conducted with a random-effects model and subgroup analyses were conducted to determine sources of heterogeneity.ResultsEight randomized controlled trials (N=1,384) contained sufficient information for inclusion. The pooled risk of stone passage in the tamsulosin arm was 85% versus 66% in the placebo arm, but substantial heterogeneity existed across trials (I2=80.2%; P&lt;.001). After stratifying of studies by stone size, the meta-analysis of the large stone subgroup (5 to 10 mm; N=514) indicated a benefit of tamsulosin (risk difference=22%; 95% confidence interval 12% to 33%; number needed to treat=5). The meta-analysis of the small stone subgroup (&lt;4 to 5 mm; N=533) indicated no benefit (risk difference=-0.3%; 95% confidence interval -4% to 3%). Neither meta-analysis for the occurrence of dizziness or hypotension showed a significant effect.ConclusionTamsulosin significantly improves stone passage in patients with larger stones, whereas the effect of tamsulosin is diminished in those with smaller stones, who are likely to pass their stone regardless of treatment

Re: Cross-Sectional and Longitudinal Associations of Sexual Function with Urinary Tract Symptoms in Men with Benign Prostatic Hyperplasia

In this study authors examine the cross-sectional associations between baseline characteristics and sexual function and the longitudinal associations between change in lower urinary tract symptoms and change in sexual function among men with benign prostatic hyperplasia. The cross-sectional cohort included 2.916 men who completed Brief Male Sexual Function Inventory (BMSFI) at baseline. The longitudinal cohort included 672 men who were randomized to placebo. Increased age, less education, obesity and severe lower urinary tract symptoms were found significantly associated poorer sexual drive, erectile dysfunction, ejaculatory function, sexual problem assessment and overall satisfaction. However, none of these baseline characteristics predicted change in sexual function in the longitudinal cohort. The decline in sexual dysfunction associated with worsening of lower urinary tract symptoms in men assigned to placebo was small
