Prospective risk of stillbirth and neonatal complications in twin pregnancies: systematic review and meta-analysis

2016

Twin pregnancies are at increased risk of stillbirth. Uncomplicated twin pregnancies are commonly delivered earlier to prevent stillbirth; however, there is a risk of neonatal complications associated with being born prior to 39 weeks’ gestation. The optimal gestational age for delivery in twin pregnancies is unknown and likely varies by chorionicity. The present study aimed to determine the prospective risk of stillbirth in women with uncomplicated monochorionic and dichorionic twin pregnancies, and neonatal mortality risks, when delivered beyond 34 weeks of gestation. Data on twin pregnancies that reported rates of stillbirth were obtained from MEDLINE, EMBASE, and Cochrane Library. Separ…

Clinical interval and diagnostic characteristics in a cohort of bladder cancer patients in Spain : a multicenter observational study

2017

Objective We performed a cohort study in seven hospitals in Spain to determine the clinical characteristics of incident patients with bladder cancer, the diagnostic process, and the conditions that might affect health care interval times. Results 314 patients with bladder cancer were included, 70.3 (Standard Deviation [SD] 11.2) years old and 85.0% male. Clinical stage was T1 in 45.9% of patients. The median interval time between first consultation and diagnosis was of 104.0 days (Inter quartile range [IQR]:112.0; range from 0 to 986), being shorter for those patients who attended a hospital for their first consultation. The median interval time between diagnosis and first treatment was of …

Quality of life in patients with non-muscle-invasive bladder cancer: one-year results of a multicentre prospective cohort study.

2014

Few studies describe the effect of non-muscle-invasive bladder cancer (NMIBC) on health-related quality of life (HRQL), although patients are mostly diagnosed at this stage of the disease. Taking into account this current evidence gap and the high incidence rates in Spain, we aimed to describe the evolution over time of HRQL in Spanish patients with NMIBC and to examine the clinical and treatment-related factors associated with HRQL change during the first year of management.Observational multicenter prospective inception cohort study conducted in urology departments of 7 Spanish hospitals. A consecutive sample of 244 patients with anatomopathologically confirmed NMIBC, recruited from Octob…

Bladder cancer index : Cross-cultural adaptation into Spanish and psychometric evaluation

2014

Background: The Bladder Cancer Index (BCI) is so far the only instrument applicable across all bladder cancer patients, independent of tumor infiltration or treatment applied. We developed a Spanish version of the BCI, and assessed its acceptability and metric properties. Methods: For the adaptation into Spanish we used the forward and back-translation method, expert panels, and cognitive debriefing patient interviews. For the assessment of metric properties we used data from 197 bladder cancer patients from a multi-center prospective study. The Spanish BCI and the SF-36 Health Survey were self-administered before and 12 months after treatment. Reliability was estimated by Cronbach's alpha.…

Clinical intervals and diagnostic characteristics in a cohort of prostate cancer patients in Spain: a multicentre observational study

2015

BACKGROUND: Little is known about the healthcare process for patients with prostate cancer, mainly because hospital-based data are not routinely published. The main objective of this study was to determine the clinical characteristics of prostate cancer patients, the, diagnostic process and the factors that might influence intervals from consultation to diagnosis and from diagnosis to treatment. METHODS: We conducted a multicentre, cohort study in seven hospitals in Spain. Patients' characteristics and diagnostic and therapeutic variables were obtained from hospital records and patients' structured interviews from October 2010 to September 2011. We used a multilevel logistic regression mode…

Agreement in metastatic spinal cord compression

2015

Background: Metastatic epidural spinal cord compression (ESCC) is a devastating medical emergency. The purpose of this study was to determine the reliability of the 6-point ESCC scoring system and the identification of the spinal level presenting ESCC. Methods: Clinical data and imaging from 90 patients with biopsy-proven spinal metastases were provided to 83 specialists from 44 hospitals. The spinal levels presenting metastases and the ESCC scores for each case were calculated twice by each clinician, with a minimum of 6 weeks' interval. Clinicians were blinded to assessments made by other specialists and their own previous assessment. Fleiss kappa (κ) statistic was used to assess intraobs…
