Examination of the Role of Religious and Psychosocial Factors in HIV Medication Adherence Rates

Optimal adherence to antiretroviral therapy (ART) is associated with favorable HIV outcomes, including higher CD4 cell counts, HIV virus suppression and a lower risk of HIV transmission. However, only 25% of people living with HIV/AIDS (PLWH) in the USA are virally suppressed. Sub-optimal adherence (p\u3c 0.05). Social support satisfaction was also significantly associated with ART adherence (OR = 1.52, 95% CI [1.11–2.08], p \u3c 0.05) and energy/fatigue/vitality (OR = 1.03, 95% CI [1.00–1.05], p \u3c 0.05)

Use of the Spiritual Development Framework in Conducting Spirituality and Health Research with Adolescents

Spirituality is considered a universal phenomenon, but research addressing the spiritual needs of adolescents in the context of health and illness is limited. The aim of this article is to provide a description of how the spiritual development framework (SDF) was used in conducting research with adolescents. An exemplar of a qualitative descriptive study is provided to demonstrate applicability of the SDF. The SDF was used as a guiding theoretical framework in conducting research with adolescents living with sickle cell disease. The SDF is culturally applicable and methodologically appropriate. Additional research applying the SDF is warranted

Study on thermosonication and ultraviolet radiation processes as an alternative to blanching for some fruits and vegetables

The impacts of ultraviolet-C radiation, blanching by heat, and combination of heat/ultrasounds (thermosonication) were studied for Listeria innocua (inoculated) in red bell peppers, total mesophiles in strawberries and total coliforms in watercress, in the temperature range 50–65 °C. Quality attributes such as colour and firmness were studied for all products, and total anthocyanins content was additionally determined for strawberries. Results showed that ultraviolet- C radiation was the least effective treatment in terms of microbial load reduction and was equivalent to a simple water washing. Log reductions were 1.05±0.52 for L. innocua, 0.53±0.25 for total coliforms and 0.26±0.18 for total mesophiles. This treatment had the lowest impact on the quality parameters analysed. Thermosonication treatment was similar to heat blanching for all microorganism/product tested, excepted for total coliforms in watercress at 65 °C, in which thermosonication had a higher effect (p<0.05). Heat blanching at 65 °C allowed 7.43±0.12 log-cycles reduction, while loads were diminished by 8.24±0.13 log-cycles if thermosonication at the same temperature was applied. Thermosonication also allowed better quality retention, when compared to heat blanching at the same temperatures. The impact of thermosonication on microbial load reductions was statistically significant and thermosonicated samples retained quality attributes better than heat blanched ones at the same temperatures (p<0.05). Hence, it can be concluded that thermosonication is a promising process and may be a favourable alternative to the conventional thermal treatments

Curcumin-loaded polymeric and lipid nanocapsules: preparation, characterization and chemical stability evaluation

Polymeric and lipid nanocapsules suspensions of the natural compound curcumin were prepared in order to overcome limitations associated with its clinical applications, such as poor aqueous solubility and susceptibility to hydrolytic and photochemical degradation. Nanocapsule suspensions were prepared by nanoprecipitation and phase inversion methods, respectively. The curcumin formulations were investigated for physicochemical characteristics and in vitro drug release. The hydrolytic and photochemical degradation of the drug associated with the nanocarriers was also determined. For all formulations, the entrapment efficiency values were higher than 99 %. The aqueous colloidal suspensions of curcumin resulted in an increase in drug concentration by a factor of up to 46.103 times. Moreover, stability studies indicated that nanoencapsulation slows down the hydrolytic and photochemical degradations of curcumin. The strategy of nanoencapsulation into polymeric and lipid nanocapsules produced a formulation of curcumin with high drug loading and improved stability, representing a good strategy for the delivery of this drug.Colegio de Farmacéuticos de la Provincia de Buenos Aire
