Given advances in care and treatment for HIV, perinatally infected young people are surviving into adolescence. These young people are making decisions about engaging in sexual relationships and it is critical to ensure they have the information they need to engage responsibly in sexual activity, particularly in an era where adherence to treatment could make their virus undetectable. The main objective of this analysis was to examine whether an HIV-positive young person's knowledge about forward transmission is associated with caregiver self-efficacy to talk about sex and general caregiver communication. Using data from a 12-month prospective cohort of caregivers of HIV-positive children aged 9–15 on ART and pre-ART in rural Zimbabwe, we found that caregiver self-efficacy to talk about sex predicted whether conversations about HIV transmission would occur between caregiver and the young person. However, by the end of 12-months, nearly two-thirds of caregivers of HIV-positive teenagers in our sample had still not explained how their adolescents could spread the virus to others despite these caregivers saying their adolescent should know this information at baseline. We discuss the implications for designing sexual and reproductive health (SRH) programs among populations of young people perinatally infected with HIV to ensure that this breakthrough generation receives the SRH support they need.

Background In the present study, we set out to compare patient-reported outcomes with professional judgment about cosmesis after breast-conserving therapy (bct) and to evaluate which items (position of the nipple, color, scar, size, shape, and firmness) correlate best with subjective outcome. Methods Dutch patients treated with bct between 2008 and 2009 were analyzed. Exclusion criteria were prior amputation or bct of the contralateral breast, metastatic disease, local recurrence, or any prior cosmetic breast surgery. Structured questionnaires and standardized six-view photographs were obtained with a minimum of 3 years' follow-up. Cosmetic outcome was judged by the patients and, based on photographs, by 5 different medical professionals using 3 different scoring systems: the Harvard scale, the Sneeuw questionnaire, and a numeric rating scale. Agreement was scored using the intraclass correlation coefficient (icc). The association between items of the Sneeuw questionnaire and a fair-poor Harvard score was estimated using logistic regression analysis. Results The study included 108 female patients (age: 40-91 years). Based on the Harvard scale, agreement on cosmetic outcome between the professionals was good (icc: 0.78). In contrast, agreement between professionals as a group compared with the patients was found to be fair to moderate (icc range: 0.38-0.50). The items "size" and "shape" were identified as the strongest determinants of cosmetic outcome. Conclusions Cosmetic outcome was scored differently by patients and professionals. Agreement was greater between the professionals than between the patients and the professionals as a group. In general, size and shape were the most prominent items on which cosmetic outcome was judged by patients and professionals alike. [ABSTRACT FROM AUTHOR]

We investigated the effects of two 5-wk periods of intermittent hypoxia on running economy (RE). 11 male and female middle-distance runners were randomly assigned to the intermittent hypoxia group (IHG) or to the control group (CG). All athletes trained for a 13-wk period starting at pre-season until the competition season. The IHG spent additionally 2 h at rest on 3 days/wk for the first and the last 5 weeks in normobaric hypoxia (15-11% FiO2). RE, haematological parameters and body composition were determined at low altitude (600m) at baseline, after the 5th, the 8th and the 13th week of training. RE, determined by the relative oxygen consumption during submaximal running, (-2.3±1.2 vs. -0.3±0.7 ml/min/kg, P<0.05) and total running time ( + 1.0±0.9 vs. +0.4±0.5min, P<0.05) changed significantly between the IHG and CG only during the first 5-wk period. Haematological and cardiorespiratory changes indicate that the improved RE was associated with decreased cardiorespiratory costs and greater reliance on carbohydrate. Intermittent hypoxia did not affect RE during the second 5-wk period. These findings suggest that the effects of intermittent hypoxia on RE strongly depend on the training phase.

This study explores how communities in Zambia characterize vulnerable children in the context of HIV; demonstrates how estimates of vulnerability vary depending on definitions; and discusses the implications of these estimates for program delivery. Baseline research conducted in 2005 included cross-sectional community-based household surveys at six locations using multi-stage random sampling (totalling 1,503 households, reporting on 5,009 children) and participatory qualitative research (focus group and in-depth interviews) with adults and youth at four locations. Between 14 and 27% of children in the sample had experienced a parental death (2-5% maternal orphans, 7-13% paternal orphans, 4-10% double orphans). In addition, other characteristics that communities associated with children's vulnerability were prevalent: 26-34% had been taken into another household, 15-27% were living in female-headed households, and 11-28% were living in a household with someone who is chronically ill. Overall, 58-73% of children had one or more community-defined characteristics of vulnerability. This study highlights the need to carefully consider the meaning of “vulnerability” when targeting programmes to support children affected by HIV and AIDS. Local community input is vital to inform context-specific criteria for distributing programme resources. If used, eligibility criteria should be context-specific yet flexible to evolving community realities. In settings such as rural Zambia where levels of HIV-related vulnerability are high, it may be more efficient to target at the level of communities rather than assess individual households.

OBJECTIVE: In response to findings from a statewide survey of hospital nurses, the authors designed, conducted, and evaluated a 'Back to Sleep' nursing curriculum and training program in Missouri hospitals using two distinct training formats. This article evaluates the initial and follow-up outcomes for training participants and assesses the impact of training format on participant outcomes. METHODS: Participants selected training format by hospital site. In each training format, participants responded to a pre and post test questionnaire measuring knowledge, beliefs, and current infant care behaviors as well as satisfaction with the training. Three months after completion of all statewide trainings, the authors also conducted a follow-up survey. RESULTS: Nurses who participated in the training reported statistically significant improvements in knowledge and 'Back to Sleep' adherent beliefs. Over 98% of participants (N = 515) intended to place infants in back-only sleep positions following the training. Knowledge, attitudes, and practice intentions were significantly improved across both training formats. Additionally, follow-up survey respondents statewide (N = 295) reported lasting improvements, including 63% of nurses reportedly using supine-only sleep position for infants after the first 24 h of life, compared to 28% in the original statewide survey. CONCLUSIONS: Further research is needed to determine the long-term impact of this intervention and assess its applicability beyond this initial implementation. Ultimately, the findings from the evaluation of this pilot intervention and nursing-specific 'Back to Sleep' curriculum demonstrate that it has a promising effect on risk-reduction adherence in hospital settings where parent observations of safe sleep behavior first occur.

This study assessed the strategy of building young people's capacity to provide care and support to people living with HIV and AIDS in rural Zambia. Members of youth anti-AIDS clubs in schools and communities were trained as adjunct caregivers using a locally developed curriculum that allowed them to explore and challenge gendered notions of caregiving and emphasized networking with existing resources. Results show that caregiving increased among males (47% to 82%) and females (41% to 78%). Both sexes provided similar caregiving services, including help with household chores and personal care tasks. Youth also undertook activities with children to decrease their isolation, help them stay in school, and reach additional services. While clients and caregivers reported positive aspects of the programme, both reported frustration with the youths’ inability to meet material needs. This study demonstrates that trained youth already involved in anti-AIDS efforts can meet a range of care needs and be valuable assets to their community. It also highlights the importance of communicating clearly what youth can and cannot do, ongoing monitoring and support of youth caregivers, and involving community leaders to give youth credibility and access to local resources.

From September 1983 to December 1985 40 patients from a total of 55 with periampullary and pancreatic head carcinoma underwent resectional surgery in our department. Following a policy of precise evaluation of each patient's operative findings, six patients underwent a Whipple duodenopancreatectomy, 29 patients underwent regional subtotal pancreatectomy, and five underwent regional total pancreatectomy. Five patients underwent vascular reconstruction of their regional vascular structures after transection of the invaded segments of their vessels and eight had positive lymph nodes. Lymph node involvement was confined to the regional area. Patients with distant lymph node involvement (paraaortic) were not considered eligible to resection. Three patients died and 10 required reoperation. Thirty-one had radical resection, one palliative and eight equivocal resection. From the survived patients (n = 37) 33 are alive and doing well at the time of this report (overall mean survival 18 months). The results of this study demonstrate that a radical approach based on a precise evaluation of operative findings of the individual patient might well offer a higher resectability rate and is probably the only chance for radical resection and for a longer survival in patients with periampullary and pancreatic head carcinoma.

Reports based on experiences from masseurs and players, mostly without any scientific background, suggest that the combination of a classical regeneration method (i.e. massage) with exposure to hypoxia may enhance regeneration in soccer. The aim of this study was to evaluate whether this specific combination could affect blood parameters related to muscle damage and physical strain after a soccer game. Approximately 15 hours after two separate championship games, 10 professional male outfield players of the first Austrian division were exposed to normobaric hypoxia (F1O2 13.5% ~ 4000m) or normoxia for 1 hour (30 minutes rest followed by 30 min massage) (cross-over design). Creatine kinase (CK), urea and uric acid (UA) were measured 4 days before the first game, and 15 and 63 hours after the two games. Match play increased CK values independently of the intervention. No effect of the massage in combination with hypoxia was seen. A trend was found between Δ UA ([UA] 48 hours after exposure minus [UA] before exposure) in response to hypoxia and SaO2 measured in hypoxia (r=0.612, p=0.06). Results show that massage under hypoxic conditions had no additional positive effect on the measured parameters compared to massage alone. Solely the trend of a relationship for Δ UA and SaO2 might indicate that redox alterations are a potential consequence of hypoxic exposure. [ABSTRACT FROM AUTHOR]
