HIV/AIDS counselling program : a rural Ghana experience

This paper describes an HIV/AIDS counselling training program which has run for two-and-ahalf years at the Holy Family Hospital, Berekum. The training is designed to teach paraprofessionals active listening skills to cope with the spiritual and emotional dimension of the person who is HIV-positive. Parallel to this training, the Hospital established counselling services which have been extended to include home visiting. Difficulties have been the need for emotional support of counsellors, a lack of time and staff, and the lack of financial resources. The overall success of the program, however, has indicated that this form of counselling training is an effective way of addressing the emotional care of persons with HIV/AIDS

EU tobacco controls and the importance of gender : time to ban slim and superslim cigarettes

The global tobacco industry have been targeting women smokers for over a century. In recent years there has been a significant growth in smoking rates among women and girls. In many Western countries, girls and young women now smoke at higher rates than their male counterparts. One area in which there has been significant growth is in the market share of slim and super-slim cigarettes. These thin diameter and extra-long cigarettes are often described as more feminine, glamorous, sexy and elegant, and as such have made dramatic inroads into declining cigarette markets in Europe. An early draft of the European Union’s (2014) Tobacco Products Directive (TPD) sought to ban the sale of such cigarettes. This prohibition was later removed. This commentary argues that in light of a need to mainstream gender equity in health and the significant growth in sales of slim and super-slim cigarettes the EU should ban sales of these cigarettes as soon as possible. In the absence of such a centralised approach, individual EU countries should follow the lead of New Zealand and ban them unilaterally.peer-reviewe

Missing p. 28The purpose of this study is to summarize the theses and dissertations which contain reading materials that have been or could be adapted for use with slow-learning cJ:lildren in the elementary school. These studies were completed at Boston University during the years 1943 through 1960

Cortisol patterns are associated with T cell activation in HIV.

ObjectiveThe level of T cell activation in untreated HIV disease is strongly and independently associated with risk of immunologic and clinical progression. The factors that influence the level of activation, however, are not fully defined. Since endogenous glucocorticoids are important in regulating inflammation, we sought to determine whether less optimal diurnal cortisol patterns are associated with greater T cell activation.MethodsWe studied 128 HIV-infected adults who were not on treatment and had a CD4(+) T cell count above 250 cells/µl. We assessed T cell activation by CD38 expression using flow cytometry, and diurnal cortisol was assessed with salivary measurements.ResultsLower waking cortisol levels correlated with greater T cell immune activation, measured by CD38 mean fluorescent intensity, on CD4(+) T cells (r = -0.26, p = 0.006). Participants with lower waking cortisol also showed a trend toward greater activation on CD8(+) T cells (r = -0.17, p = 0.08). A greater diurnal decline in cortisol, usually considered a healthy pattern, correlated with less CD4(+) (r = 0.24, p = 0.018) and CD8(+) (r = 0.24, p = 0.017) activation.ConclusionsThese data suggest that the hypothalamic-pituitary-adrenal (HPA) axis contributes to the regulation of T cell activation in HIV. This may represent an important pathway through which psychological states and the HPA axis influence progression of HIV

Differential Calcium Dependence of Axonal Versus Somatodendritic Dopamine Release, with Characteristics of Both in the Ventral Tegmental Area

Midbrain dopamine (DA) neurons in the substantia nigra pars compacta (SNc) and ventral tegmental area (VTA) exhibit somatodendritic release of DA. Previous studies indicate a difference between the Ca2+ dependence of somatodendritic DA release in the SNc and that of axonal DA release in dorsal striatum. Here, we evaluated the Ca2+ dependence of DA release in the VTA and nucleus accumbens (NAc) shell for comparison with that in the SNc and dorsal striatum. Release of DA was elicited by single-pulse stimulation in guinea-pig brain slices and monitored with subsecond resolution using carbon-fiber microelectrodes and fast-scan cyclic voltammetry. In dorsal striatum and NAc, DA release was not detectable at extracellular Ca2+ concentrations ([Ca2+]o) below 1 mM; however, a progressive increase in evoked extracellular DA concentration ([DA]o) was seen with [Ca2+]o ≥ 1.5 mM. By contrast, in SNc and VTA, robust increases in [DA]o could be elicited in 0.25 mM [Ca2+]o that were ∼60% of those seen in 1.5 mM [Ca2+]o. In SNc, a plateau in single-pulse evoked [DA]o was seen at [Ca2+]o ≥ 1.5 mM, mirroring the release plateau reported previously for pulse-train stimulation in SNc. In VTA, however, evoked [DA]o increased progressively throughout the range of [Ca2+]o tested (up to 3.0 mM). These functional data are consistent with the microanatomy of the VTA, which includes DA axon collaterals as well as DA somata and dendrites. Differences between axonal and somatodendritic release data were quantified using Hill analysis, which showed that the Ca2+ dependence of axonal DA release is low affinity with high Ca2+ cooperativity, whereas somatodendritic release is high affinity with low cooperativity. Moreover, this analysis revealed the dual nature of DA release in the VTA, with both somatodendritic and axonal contributions

FAK Deletion Promotes p53-Mediated Induction of p21, DNA-Damage Responses and Radio-Resistance in Advanced Squamous Cancer Cells

Focal adhesion kinase (FAK) is a cytoplasmic tyrosine kinase that is elevated in a variety of human cancers. While FAK is implicated in many cellular processes that are perturbed in cancer, including proliferation, actin and adhesion dynamics, polarisation and invasion, there is only some limited information regarding the role of FAK in radiation survival. We have evaluated whether FAK is a general radio-sensitising target, as has been suggested by previous reports. We used a clean genetic system in which FAK was deleted from mouse squamous cell carcinoma (SCC) cells (FAK −/−), and reconstituted with exogenous FAK wild type (wt). Surprisingly, the absence of FAK was associated with increased radio-resistance in advanced SCC cells. FAK re-expression inhibited p53-mediated transcriptional up-regulation of p21, and a sub-set of other p53 target genes involved in DNA repair, after treatment with ionizing radiation. Moreover, p21 depletion promoted radio-sensitisation, implying that FAK-mediated inhibition of p21 induction is responsible for the relative radio-sensitivity of FAK-proficient SCC cells. Our work adds to a growing body of evidence that there is a close functional relationship between integrin/FAK signalling and the p53/p21 pathway, but demonstrates that FAK's role in survival after stress is context-dependent, at least in cancer cells. We suggest that there should be caution when considering inhibiting FAK in combination with radiation, as this may not always be clinically advantageous

Effects of a mindfulness-based weight loss intervention in adults with obesity: A randomized clinical trial.

OBJECTIVE: To determine whether adding mindfulness-based eating and stress management practices to a diet-exercise program improves weight loss and metabolic syndrome components. METHODS: In this study 194 adults with obesity were randomized to a 5.5-month program with or without mindfulness training and identical diet-exercise guidelines. Intention-to-treat analyses with multiple imputation were used for missing data. The primary outcome was 18-month weight change. RESULTS: Estimated effects comparing the mindfulness to control arm favored the mindfulness arm in (a) weight loss at 12 months, -1.9 kg (95% CI: -4.5, 0.8; P = 0.17), and 18 months, -1.7 kg (95% CI: -4.7, 1.2; P = 0.24), though not statistically significant; (b) changes in fasting glucose at 12 months, -3.1 mg/dl (95% CI: -6.3, 0.1; P = 0.06), and 18 months, -4.1 mg/dl (95% CI: -7.3, -0.9; P = 0.01); and (c) changes in triglyceride/HDL ratio at 12 months, -0.57 (95% CI: -0.95, -0.18; P = 0.004), and 18 months, -0.36 (95% CI: -0.74, 0.03; P = 0.07). Estimates for other metabolic risk factors were not statistically significant, including waist circumference, blood pressure, and C-reactive protein. CONCLUSIONS: Mindfulness enhancements to a diet-exercise program did not show substantial weight loss benefit but may promote long-term improvement in some aspects of metabolic health in obesity that requires further study
