ABSTRACT Objectives Worldwide scientific production on Oral Health Related Quality of Life (OHRQL) has not been explored. The objective of this study was to perform a bibliometric analysis of global research productivity on OHRQL. Methods An electronic search for original articles was conducted using the Web of Science database, with the terms: “Oral Health Related Quality of Life” AND “OHRQL”. Bibliometric indicators were investigated by analyzing annual research output, languages, countries, journals, authors, institutions, and citations. Results Bibliographic research retrieved 1099 papers for the period 1996-2016. The yearly quantitative distributions of articles were highly correlated (R2=0.90). The mostly used languages were English (1084 articles), Portuguese (6 articles) and German (5 articles). Retrieved articles were published by 73 different countries. The largest cont...

Objective: To estimate and analyze the evolution of mortality rates of gastrointestinal (GI) cancer in Peru and its regions between 2005-2014. Material and methods: We performed a nationwide secondary analysis of Peru’s Health Ministry registry of deaths during the period 2005-2014, with a focus on regional differences. Deaths registered with codes C15 to C25 (malignant neoplasms of digestive organs) from the ICD-10 were included. Calculation of age-standarized mortality rates and years of life lost (YLL) due to GI cancer per 100,000 habitants were also performed. Results: Data of 67,527 deaths from GI cancers was analyzed, 35,055 (51.91%) were women. In 2005, the number of GI cancer deaths was 6,484, for 2014, 7,532 cases were recorded. The GI cancer age-standarized mortality rates at the country level showed a decrease of 12.70% between 2005-2014. Stomach cancer presented the highest...

ABSTRACT Objective: To assess the prevalence of drug abuse before prison admission and to identify associated sociodemographic and family history risk factors, according to gender, in prisons of Peru. Materials and methods: A secondary analysis was carried out with data from the First National Prisoner Census 2016, using a questionnaire of 173 items that was applied to the whole prison population of Peru. The types of drugs used before admission were analyzed according to characteristics of the penitentiary population, and generalized linear models were used to calculate prevalence ratios with 95% confidence intervals to identify possible factors associated with drug use. Results: Out of a population of 76,180 prisoners, 71,184 (93.4%) answered the survey (men 67,071, 94.2%). The overall prevalence of drug consumption before admission was 24.4% (25.3% in men and 9.1% in women), the highe...
