Sleep quality and sleep deprivation: relationship with academic performance in university students during examination period.

The beginning of the university brings together maturational, psychosocial and academic changes that make university students more prone to suffer from insufficient or poor quality sleep, which can negatively influence their academic performance. The period of taking exams is a key part of the academic year. However, there are few studies that analyze sleep during this period of time.

Predictive and criterion validity of the Cervantes-SF menopause quality of life questionnaire.

Objectives: To determine the predictive and criterion-based validity of the Cervantes-SF scale that measures the impact of menopause on Health-Related Quality of Life.

Methods: We recruited a noninstitutionalized sample of peri/postmenopausal women aged 40 to 65 years, who had their last menstrual cycle 12+ months prior to inclusion in the study of the psychometric validity of the Cervantes-SF scale. Predictive validity of the scale was confirmed for various health outcome measures administered concomitantly (years of disability-free life expectancy, work productivity and impact on daily activities, economic impact arising from loss of work productivity, hours of undisturbed sleep each day, and the utilization of healthcare facilities), whilst criterion validity was determined by the likelihood of identifying a moderate-to-severe vasomotor or genital syndrome requiring specific treatment.

Population-based norms for the Cervantes-SF short-form questionnaire assessing health-related quality of life in menopause.

Objectives: To develop the population-based norms for the Cervantes-SF scale, which measures the impact of menopause on the health-related quality of life (HRQOL) of women in Spain.

Methods: We used a sample obtained from representative studies of the Spanish population according to geographic density and autonomous community. This sample was composed of 5,237 non- institutionalized peri- and post-menopausal women, aged 40-75 years.

Mapping of the Gastrointestinal Short Form Questionnaire (GSF-Q) into EQ-5D-3L and SF-6D in patients with gastroesophageal reflux disease.

Background: The short, self-administered Gastroesophageal Reflux Disease (GERD) Symptom Frequency Questionnaire (GSFQ) is a specific Quality of Life (QoL) instrument which measures the impact of GERD symptoms on QoL. This study aims to map the specific scores in GSFQ into two generic instruments: SF-6D and EQ-5D-3 L, in order to obtain utility estimates derived from the GERD condition.

Method: A national representative sample of GERD patients was selected, stratified by gender, age (< 45, ≥45 years) and GERD severity (0-I, II-IV Savary-Miller score) for validation purposes.

Mapping of the OAB-SF Questionnaire onto EQ-5D in Spanish Patients with Overactive Bladder.

Background And Objective: Mapping disease-specific measures onto generic preference-based indexes allows estimating utility values in specific conditions to determine gain of quality-adjusted-life-years when the status of condition varies. The aim of this study was to map a disease specific scale, the Overactive Bladder Questionnaire 5-dimensional health classification system (OAB-5D) derived from the Overactive Bladder questionnaire-Short Form (OABq-SF), onto a preference-based scale, the EuroQol-5D (EQ-5D), in a sample of patients with overactive bladder (OAB) in a Spanish population.

Method: A survey addressed to value the health states was conducted among 246 patients at 18 clinics of urology from Spain.

Prediction of diabetic nephropathy using urine proteomic profiling 10 years prior to development of nephropathy.

Objective: We examined whether proteomic technologies identify novel urine proteins associated with subsequent development of diabetic nephropathy in subjects with type 2 diabetes before evidence of microalbuminuria.

Research Design And Methods: In a nested case-control study of Pima Indians with type 2 diabetes, baseline (serum creatinine <1.2 mg/dl and urine albumin excretion <30 mg/g) and 10-year urine samples were examined.
