Objective: The participation of Puerto Rico in the Latin American Vertebral Osteoporosis Study (LAVOS) has allowed us to study the magnitude of the problem of osteoporosis in the female population residing in San Juan. The objective of LAVOS was to estimate the prevalence of vertebral fractures in Latin American women using a random sample of females selected from cities across five Latin American countries. Methods: A probability cluster design was employed to select a random sample of households in San Juan, Puerto Rico, in order to interview 400 females aged 50 years and over. A 30-minute face-to-face interview gathered data on demographics, risk factors, and life styles. Data regarding bone mineral densities of the spine and hip by DXA and lateral dorsolumbar X-rays were obtained using international protocols; digital morphometry was used to determine vertebral deformities, with the results being classified according to Eastell criteria. This article summarizes the main findings observed in San Juan, Puerto Rico. Results: Overall weighted prevalence of vertebral fractures was 11.2% (95% CI: 8.5%, 14.7%). Age-specific prevalence of vertebral fractures was as follows: 5.4% (95% CI: 2.7%, 10.7%) in the 50-59 years age group, 8.3% (95% CI: 4.4%, 15.1%) in the 60-69 years group, 16.2% (95% CI: 10.5%, 25.0%) in the 70-79 years group, and 22.4% (95% CI: 13.3%, 35.1%) in participants ≥80 years. Factors significantly associated with vertebral fractures were being 70-79 years old (adjusted POR70-79 vs. 50-59 = 2.9; 95% CI: 1.1, 7.4), being ≥80 years old (adjusted POR>80 vs. 50-59 = 3.3; 95% CI: 1.2, 9.4), and a T-score ≤-2.5 in the lumbar spine (adjusted POR = 2.5; 95% CI: 1.5, 5.7) and in the femoral neck (adjusted POR = 3.5; 95% CI: 1.5, 8.0). Personal history of fractures was marginally associated with vertebral fractures after adjusting for the remaining risk factors (adjusted POR = 2.0; 95% CI: 1.0, 4.0). Nearly 94% of the women with vertebral fractures were not aware of their bone status. Using the WHO classification, we determined that 71% had osteoporosis, 21%, osteopenia, and 8%, normal bone mineral densities. Bone mineral densities in the lumbar spine and femoral neck were significantly lower in women with vertebral fractures. Non-vertebral fractures were more common in women with a personal history of prior vertebral fractures. The prevalence of the most common non-vertebral fractures were hip, 1% (95% CI: 0.4%, 2.7%), and wrist, 5.9% (95% CI: 4.0%, 8.7%), respectively. Conclusion: This is the first population-based study of osteoporotic fractures in Puerto Rico and should serve as a guide to health providers and policy makers in the prevention and treatment of this disease.

Genome-wide association study of HLA-DQB1*06:02 negative essential hypersomnia

Essential hypersomnia (EHS), a sleep disorder characterized by excessive daytime sleepiness, can be divided into two broad classes based on the presence or absence of the HLA-DQB1*06:02 allele. HLA-DQB1*06:02-positive EHS and narcolepsy with cataplexy are associated with the same susceptibility genes. In contrast, there are fewer studies of HLA-DQB1*06:02 negative EHS which, we hypothesized, in...

Influence of Hero Apical instruments on cleaning ovoid-shaped root canals.

The cleaning capacity of Hero 642 nickel-titanium files, complemented by the Hero Apical instruments in flattened roots, was determined by histological analysis, considering the area of action of the instruments on the coronal walls and the presence of remaining debris. Twenty-four single-canal, human mandibular incisors were divided into three groups and prepared as follows: GI, instrumented w...
