Drop-out of medical follow-up among people living with HIV in Tel-Aviv area.

Access to HIV anti-retroviral treatment (ART) has significantly improved survival and the quality of life of people living with HIV (PLHIV). However, effective therapy necessitates high adherence to ART. The aim of this study was to identify the extent to which PLHIV in Israel were not retained in therapy and their obstacles to accessing care. The Department of Tuberculosis and AIDS (DTA) and the two existing HIV clinics in the Tel-Aviv metropolitan area performed a retrospective study for all PLHIV who were consulted at these clinics during 2008-2011, but were absent in 2012. From that population, 25% were randomly chosen for qualitative interviews. This study included 278 PLHIV not retained in care (13.4% of registered patients), of whom 194 (69.8%) were male, and 58.3% were Israeli citizens. Total number of clinic visits was 1959 (mean: 7.05 visits per patient; range: 1-39; SD: ±7.2) and the total person-years of follow-up for 267 PLHIV was 1,044 (mean: 3.9 py; 0-23; SD: ±4.4). Identified risk groups were: Originating from Generalized Epidemic countries (43.5%, 82.6% were non-Israelis); Men having Sex with Men (22.6%); Injecting Drug Users (12.9%) and Others (28.9%). Among Israelis, major reasons for clinic nonattendance included distance to the clinics and perceived lack of time. The major impediment to seeking care among undocumented migrants was lack of medical insurance. The DTA acted swiftly to make HIV-related services accessible to undocumented migrants. Barriers described by Israeli participants were generally more individual in nature, and should be addressed at the clinic level.

The effect of prophylactic treatment with risedronate on stress fracture incidence among infantry recruits.

When subjected to strains or strain rates higher than usual, the bone remodels to repair microdamage and to strengthen itself. During the initial resorption phase of remodeling, the bone is transitorily weakened and microdamage can accumulate leading to stress fracture. To determine whether short-term suppression of bone turnover using bisphosphonates can prevent the initial loss of bone during the remodeling response to high bone strain and strain rates and potentially prevent stress fracture, we conducted a randomized, double-blind, placebo-controlled trial of 324 new infantry recruits known to be at high risk for stress fracture. Recruits were given a loading dose of 30 mg of risedronate or placebo daily for 10 doses during the first 2 weeks of basic training and then a once a week maintenance dose for the following 12 weeks. Recruits were monitored by biweekly orthopedic examinations during 15 weeks of basic training for stress fractures. Bone scans for suspected tibial and femoral stress fractures and radiographs for suspected metatarsal stress fractures were used to verify stress fracture occurrence. By the intention-to-treat analysis and per-protocol analysis, there was no statistically significant difference in the tibial, femoral, metatarsal, or total stress fracture incidence between the treatment group and the placebo. We conclude that prophylactic treatment with risedronate in a training population at high risk for stress fracture using a maintenance dosage for the treatment of osteoporosis does not lower stress fracture risk.
