OBJECTIVE: This study was to determine the frequency of HPV-hr and describe the distribution by categories (HPV16, HPV18, HPV-hr non16/18) among unvaccinated asymptomatic women in Peru over a 6-year period (2013-2018). In addition, the disease clearance rate is assessed in a percentage of cases. RESULTS: Of the 6,665 samples, 2,240 (33.6%) tested positive for HPV. Among the positive cases, single-genotype infections were caused by HPV-16 (14.8%), followed by HPV-18 (2.2%) and clustered high-risk HPV (HR-HPV) genotypes (66.7%). Multiple HPV-16 infections were more common than HPV-18 infections. In addition, 22 cases (1%) presented with infection with HPV-16, HPV-18, and HR-HPV genotypes. A subset of 116 samples from patients with 1 to 2 years of follow-up was analyzed further. Clearance rates were high, at 68.8% for HPV-16 infections and 67.5% for HR-HPV infections. However, the elimination rate of multiple infections with HPV-16 and HR-HPV genotypes was slightly lower, at 55.6%.
Sleep-disordered breathing are frequent processes in Spain. Among them, the obstructive sleep apneas are the best known although not all studies are performed with the same diagnostic criteria with regard to the percentage of apneas and hypopneas per hour of sleep and the need to consider the presence or absence of clinic symptoms. After a reference to the biggest epidemiologic studies performed in different populations, the data of the major populational studies in our environs are analyzed.
