Vertical Transmission of HIV–An Update

One of the greatest successes in AIDS research to date has by far been the discovery of successful interventions that interrupt the transmission of HIV from mother to child. It is however important to note that these successes have occurred largely in countries with great resources and the least burden of perinatal transmission of HIV. In the developing world wherein currently 95% of vertical transmission of HIV occurs, it is highly condemnable that still every minute an infected infant is said to be born in spite of the fact that vertical transmission is largely preventable, mainly because translating knowledge into practice is not always possible or feasible; This has led to a continuous growing numbers of children with HIV, thereby making pediatric HIV a looming problem rapidly draining the already burdened health care system of these countries. It is the need of the hour to appropriately address the challenges to achieve zero percent transmission of HIV from an infected mother to her child thereby giving a hope for an AIDS-free new generation worldwide.     

Risk Factors for Varicella Susceptibility Among Refugees to Toronto,Canada

Several outbreaks of varicella have occurred among refugees. We aimed to estimate the prevalence of varicella susceptibility among refugees, and identify risk factors for varicella susceptibility. All refugees rostered at Crossroads Clinic in Toronto, Canada in 2011–2014 were included in our study. Varicella serology was assessed at the initial visit. Refugees’ age, sex, education, time since arrival, and climate and population density of birth country were abstracted from the chart. Multivariate logistic regression was used to identify risk factors for varicella susceptibility. 1063 refugees were rostered at Crossroads Clinic during the study; 7.9 % (95 % CI 6.1, 9.7) were susceptible to varicella. Tropical climate (OR 3.20, 95 % CI 1.53, 6.69) and younger age (OR_{per year of age} 0.92, 95 % CI 0.88–0.96) were associated with increased varicella susceptibility. These risk factors for varicella susceptibility should be taken into account to maximize the cost-effectiveness of varicella prevention strategies among refugees.     

Effectiveness and safety profiling of zolpidem and acupressure in CKD associated pruritus: An interventional study

Background:Chronic kidney disease (CKD)-associated pruritus (CKD-aP) contributes to poor quality of life, including reduced sleep quality and poor sleep quality is a source of patient stress and is linked to lower health-related quality of life. This study aimed to investigate the effectiveness of zolpidem 10 mg and acupressure therapy on foot acupoints to improve the sleep quality and overall quality of life among hemodialysis patients suffering from CKD-aP.Method:A multicenter, prospective, randomized, parallel-design, open label interventional study to estimate the effectiveness of zolpidem (10 mg) oral tablets versus acupressure on sleep quality and quality of life in patients with CKD-aP on hemodialysis. A total of 58 hemodialysis patients having sleep disturbance due to CKD-aP completed the entire 8-week follow-up. The patients were divided into a control (acupressure) group of 28 patients and an intervention (zolpidem) group of 30 patients.Results:A total of 58 patients having CKD-aP and sleep disturbance were recruited. In the control group there was a reduction in the PSQI score with a mean ± SD from 12.28 ± 3.59 to 9.25 ± 3.99, while in the intervention group the reduction in PSQI score with a mean ± SD was from 14.73 ± 4.14 to 10.03 ± 4.04 from baseline to endpoint. However, the EQ5D index score and EQ-visual analogue scale (VAS) at baseline for the control group with a mean ± SD was 0.49 ± 0.30 and 50.17 ± 8.65, respectively, while for the intervention group the values were 0.62 ± 0.26 and 47.17 ± 5.82, respectively. The mean EQ5D index score in the control group improved from 0.49 ± 0.30 to 0.53 ± 0.30, but in the intervention group there was no statistical improvement in mean EQ5D index score from 0.62 ± 0.26 to 0.62 ± 0.27 from baseline to week 8. The EQ 5D improved in both groups and the EQ-VAS score was 2.67 points higher at week 8 as compared to baseline in the control group, while in the intervention group the score was 3.33 points higher at week 8 as compared to baseline. Comparing with baseline, the PSQI scores were significantly reduced after week 4 and week 8 (P =  < .001). Furthermore, at the end of the study, the PSQI scores were significantly higher in the control as compared to the intervention group (P = .012).Conclusion:An improvement in sleep quality and quality of life among CKD-aP patients on hemodialysis has been observed in both the control and intervention groups. Zolpidem and acupressure safety profiling showed no severe adverse effect other that drowsiness, nausea and daytime sleeping already reported in literature of zolpidem.
