Background
Early identification and entry into care is critical to reducing morbidity and mortality in children with HIV. The objective of this report is to describe the impact of the Tingathe programme, which utilizes community health workers (CHWs) to improve identification and enrolment into care of HIV-exposed and -infected infants and children.Methods
Three programme phases are described. During the first phase, Mentorship Only (MO) (March 2007–February 2008) on-site clinical mentorship on paediatric HIV care was provided. In the second phase, Tingathe-Basic (March 2008–February 2009), CHWs provided HIV testing and counselling to improve case finding of HIV-exposed and -infected children. In the final phase, Tingathe-PMTCT (prevention of mother-to-child transmission) (March 2009–February 2011), CHWs were also assigned to HIV-positive pregnant women to improve mother-infant retention in care. We reviewed routinely collected programme data from HIV testing registers, patient mastercards and clinic attendance registers from March 2005 to March 2011.Results
During MO, 42 children (38 HIV-infected and 4 HIV-exposed) were active in care. During Tingathe-Basic, 238 HIV-infected children (HIC) were newly enrolled, a six-fold increase in rate of enrolment from 3.2 to 19.8 per month. The number of HIV-exposed infants (HEI) increased from 4 to 118. During Tingathe-PMTCT, 526 HIC were newly enrolled over 24 months, at a rate of 21.9 patients per month. There was also a seven-fold increase in the average number of exposed infants enrolled per month (9.5–70 patients per month), resulting in 1667 enrolled with a younger median age at enrolment (5.2 vs. 2.5 months; p<0.001).During the Tingathe-Basic and Tingathe-PMTCT periods, CHWs conducted 44,388 rapid HIV tests, 7658 (17.3%) in children aged 18 months to 15 years; 351 (4.6%) tested HIV-positive. Over this time, 1781 HEI were enrolled, with 102 (5.7%) found HIV-infected by positive PCR. Additional HIC entered care through various mechanisms (including positive linkage by CHWs and transfer-ins) such that by February 2011, a total of 866 HIC were receiving care, a 23-fold increase from 2008.Conclusions
A multipronged approach utilizing CHWs to conduct HIV testing, link HIC into care and provide support to PMTCT mothers can dramatically improve the identification and enrolment into care of HIV-exposed and -infected children. 相似文献2.

Background: Individuals who fail to show a decline in blood pressure (BP) when asleep or at night (labeled nocturnal nondippers) are
at elevated risk for hypertension and associated targetorgan damage.Purpose: We tested whether the well-established changes in BP exhibited in response to daily activities are also blunted in nocturnal
nondippers.Methods: Cross-sectional study of 41 women and 56 men, aged 27 to 71 years, residing in Benin, Nigeria, enrolled in a health survey
of civil servants. Ambulatory 24-hr BP monitoring was performed with concurrent diary recordings of physical activity level,
posture, location, state of mental activity, interpersonal interaction, and mood obtained during the waking hours.Results: Nocturnal nondippers exhibited smaller cardiovascular responses to changes in posture (from lying to sitting or to standing,
ps <.02), location (from home to work or to driving/riding in a car, ps < .02), mental activity (from relaxed to active, p
=. 02), and mood (from feeling mellow to feeling elated-happy, p = .05) than did dippers. Statistical controls for posture
substantially reduced the effects of nondipping status on responses to other daily activities and mood. Lack of systolic BP
responsiveness to postural changes during the day is a strong predictor of nondipping status.Conclusions: Nondipping at night appears to extend to decreased cardiovascular responses to changes in activities during daytime hours.

In Malawi, children with central nervous system (CNS) tumours are seldom able to be treated with curative intent. A study was undertaken of 29 children who underwent CNS MRI during a two year period. A combination of neoplastic and non-neoplastic diagnoses were noted, seven of which were revised on review. As a result an effective system has been set up for remote urgent review to guide prognosis and treatment. The opinion of a paediatric neuro-radiologist greatly assists in differentiating infectious and non infectious causes of CNS lesions and can enable the local team to effectively triage patients. 相似文献

Falciparum malaria is characterized by cytoadherence of host erythrocytes containing mature asexual-stage parasites and the consequent sequestration of these forms in tissue microvasculature. A postmortem study of pediatric malaria provided us with the opportunity to compare the genetic complexity of circulating and sequestered Plasmodium falciparum populations, in patients with fatal cerebral malaria (CM) versus control subjects with incidental P. falciparum parasitemia who died of causes other than malaria. Parasite genotypes identified in peripheral blood collected at the time of admission to the hospital constituted a subset of those detected in the tissues at death. Despite a higher tissue burden of parasitized erythrocytes in patients with CM than in parasitemic control subjects, parasite populations in tissues from patients with CM were less genetically complex, and the genotypes were more homogeneously distributed throughout the body, than in patients with incidental infection. Our findings support the notion that CM is associated with the emergence of a small number of dominant genotypes in an infected individual. 相似文献

ObjectivesTo examine the immediate and long-term effects of executive attention training on selective attention, focused attention, and divided attention in older adults with mild cognitive impairment.MethodsA double-blind, multisite randomized controlled trial at five sites. Seventy participants (mean age: 78.19 ± 7.22 years) were assigned to an experimental group (executive attention training, n = 35) or an active control group (n = 35). The training duration was the same for both groups (45 minutes per session, 3 times per week, 18 sessions in total). Primary outcome measure was selective attention (Digit Span Task). Secondary outcome measures included focused attention (Stroop Color Word Test) and divided attention (Trail-Making Test Part B). Data were collected at pretest, post-test, 3-month follow-up, and 6-month follow-up.ResultsIn GEE analysis, findings indicated a significant improvement in selective attention at post-test, whereas divided attention showed significant reducing omission error at 3-month follow-up. There was no significant effect of group in focused attention associated with the executive attention training compared with active control group.ConclusionThe executive attention training significantly improved selective attention and divided attention performance. Future studies should identify transfer effects of attention training, and that can employ early screening to provide integrated attention training, and decrease its relevant risks on competency in performing daily activities, such as falling and driving. 相似文献
