Gender inequality is at the core of the HIV patterns that are evident in sub-Saharan Africa. Gender-based violence (GBV) and lack of economic opportunity are important structural determinants of HIV risk. We piloted a microfinance and health promotion intervention among social networks of primarily young men in Dar es Salaam. Twenty-two individuals participated in the microfinance component and 30 peer leaders were recruited and trained in the peer health leadership component. We collected and analysed observational data from trainings, monitoring data on loan repayment, and reports of peer conversations to assess the feasibility and acceptability of the intervention. Eighteen of the loan recipients (82%) paid back their loans, and of these 15 (83%) received a second, larger loan. Among the loan defaulters, one died, one had chronic health problems, and two disappeared, one of whom was imprisoned for theft. The majority of conversations reported by peer health leaders focused on condoms, sexual partner selection, and HIV testing. Few peer leaders reported conversations about GBV. We demonstrated the feasibility and acceptability of this innovative HIV and GBV prevention intervention. The lessons learned from this pilot have informed the implementation of a cluster-randomised trial of the microfinance and peer health leadership intervention. 相似文献

Interaction between anti-inflammatory drugs and reactive oxygen metabolites must be considered in the course of pharmacological studies intended to develop new compounds. Effects of indomethacin, aspirin, and 3,5-diisopropylsalicylic acid (3,5-DIPS) and their copper complexes on PMNL oxidative metabolism and the evolution of an acute inflammatory reaction were studied in the rat. Experiments were performed in vitro by assessment of superoxide generation and reduction of chemiluminescence by PMNLs incubated or not (control) in medium containing various concentrations of these compounds. A dose-related decrease of these parameters was observed, however, copper complexes were found to be more effective than their parent drugs or Cu gluconate. Copper complexes were also more effective anti-inflammatory agents than their parent ligands or Cu gluconate when the volume of exudate and number of exudate PMNLs were assessed after induction of pleurisy in rats by injection of isologous serum. It is concluded that modulation of the PMNL oxidative burst by copper complexes offers an accounting for the anti-inflammatory activity of these compounds. 相似文献

Purpose Studies on musculoskeletal manifestations (MSM) of childhood acute lymphoblastic leukemia (ALL) have yielded variable findings
with regard to their clinical impact. We investigated the significance for differential diagnosis, treatment and outcome of
musculoskeletal complaints as presenting symptoms of ALL, and their correlation with leukemia immunophenotypes, for which
data is lacking.
Methods Data on 783 children in the national study for childhood ALL between 1984 and 2003 were reviewed retrospectively. Statistical
analysis examined possible relationships between MSM at the time of diagnosis and demographic and clinical data, biological
features of leukemia (peripheral blood counts, immunophenotype and main cytogenetic aberration), response to initial prednisone
treatment, and outcome.
Results Of 765 children with data on orthopaedic complaints, 240 presented with MSM (31.4%). Among these children, B cell precursor
(BCP) was much more common (209/576, 36.3%) than T cell ALL (25/176, 14.2%). Patients with MSM had lower white blood cell
counts (WBC) (median of 9 vs. 20 × 109/L, P < 0.001) and percentage of blast cells in the peripheral blood at diagnosis compared to those without (median of 27 vs. 53%,
P < 0.001). Hepatomegaly and splenomegaly were less common in MSM group (67 vs. 53% <3 cm, P < 0.001, and 63 vs. 50% <3 cm, P < 0.001, respectively). Poor response to initial treatment with prednisone was recorded in 7.1% of patients with MSM versus
11.5% of those without (P = 0.086). The analysis revealed no independent effect of MSM on event-free survival (EFS), after correcting for differences
in EFS related to immunophenotype or initial WBC.
Conclusions MSM occur mostly in children with BCP ALL who present with less involvement of extramedullary organs, low peripheral blood
blasts and white blood cells counts. These findings highlight the importance of including ALL in the differential diagnosis
of MSM even in the presence of an apparently normal peripheral blood count. Our study also suggests that MSM are caused by
leukemic cells with enhanced biological propensity to remain relatively confined within the intramedullary bone-marrow space. 相似文献

Antiinflammatory activities and modulations of PMNL responses produced by treatment with tetrakis--2-[3-(trifluoromethyl)-phenyl] aminonicotinatodicopper (II) [Cu(II)2(niflumate)4] and niflumic acid were studied in isologous serum-induced rat pleurisy. Doses of 10 or 30 mg/kg (35 or 106 µmol/kg) of niflumic acid or Cu(II)2 (niflumate)4 (8 or 23 µmol/kg) caused significant (p < 0.01) reductions in pleural exudate and number of polymorphonuclear leukocytes (PMNLs) in the exudate. While both doses of Cu(II)2(niflumate)4 produced significant dose-related reductions in both parameters, only the higher dose of niflumic acid produced a significant dose-related reduction in both parameters. Boyden chamber measurements of N-formyl-methionyl-leucyl-phenylalanine (f-MLP) chemotaxis by PMNLs incubated with 10 or 30 µg/ml niflumic acid (35 or 106 nmol/ml) or Cu(II)2(niflumate)4 (8 or 23 nmol/ml) were significantly (p < 0.01 to p < 0.001) decreased in dose-related fashions. Chemotaxis of PMNLs from pleuritic rats treated orally with 10 or 30 mg/kg niflumic acid or Cu(II)2(niflumate)4 was significantly (p < 0.001) inhibited by the larger dose of niflumic acid and both doses of Cu(II)2(niflumate)4. Opsonized zymosan (OZ)-stimulated chemiluminescence (CL) of PMNLs from pleuritic rats treated orally with these same doses of niflumic acid or Cu(II)2(niflumate)4 was only significantly (p < 0.05 or p < 0.01 respectively) decreased by the larger doses. Superoxide (O

) production by these cells was significantly decreased by the larger dose of niflumic acid (p < 0.05) while both doses of Cu(II)2(niflumate)4 produced significant (p < 0.05 to p < 0.01) decreases. Recovery of the decreased PMNL response in burned rats was also studied following treatment with these two compounds. Oral treatment of non-burned rats with 1 mg/kg niflumic acid (4 µmol/kg) or Cu(II)2(niflumate)4 (1 µmol/kg) did not affect OZ-stimulated O

production in non-treated scald-burned rats was reversed by oral treatment with either niflumic acid or Cu(II)2(niflumate)4. It is concluded that Cu(II)2(niflumate)4 is a more effective antiinflammatory agent than niflumic acid and more effective modulation of PMNL responsiveness may explain its beneficial antipleuritic and burn-injury recovery effects. Formation of the copper complex of niflumic acidin vivo may also account for its beneficial antiinflammatory effects and recovery of depressed PMNL responsiveness in burned rats. 相似文献

OBJECTIVE: Fever is a common cause of children visits to emergency units. Clinical evaluation does not always eliminate a bacterial infection. Among blood markers, several publications showed the interest of CRP. This study was undertaken to evaluate correlation between two techniques of CRP, one by usual technique at the laboratory and the other by a rapid test, and to evaluate the impact of this rapid test for febrile children at the emergency room, when a hospitalization was not immediately decided. MATERIAL AND METHODS: The study was undertaken in 2004-2005 in eight emergency paediatric units in Ile-de-France concerning febrile children during two periods. In period A, children had at the same time a CRP dosage through two methods, whereas in period B, only a rapid CRP test was first managed. The test used was NycoCard CRP Single test (Progen Biotechnique). RESULTS: Between September 2004 and June 2005, 572 children were included, 268 in period A and 304 in period B. Comparison of CRP results by the two methods showed for 247 children (93%) a fairly good linear correlation (r: 0.929). Blood cell count was the most often prescribed test (99.4 vs 10.5%). Conversely to chest radiography, blood culture, fibrinogen and urinary test were significantly most frequent in period A. The average cost of the additional examinations was 2.6 times more important during the first period. Duration of children management in the units was approximately two times shorter when rapid CRP test was used (199.7+/-92.8 vs 103.5+/-98.6 min). CONCLUSION: This study shows the interest of rapid CRP test for febrile children in the emergency units, and has to be confirmed in ambulatory paediatric practice. 相似文献

OBJECTIVE:: To determine predictors of fistula repair outcomes 3 months postsurgery. METHODS:: We conducted a multicountry prospective cohort study between 2007 and 2010. Outcomes, measured 3 months postsurgery, included fistula closure and residual incontinence in women with a closed fistula. Potential predictors included patient and fistula characteristics and context of repair. Multivariable generalized estimating equation models were used to generate adjusted risk ratios (RRs) and 95% confidence intervals (CIs). RESULTS:: Women who returned for follow-up 3-month postsurgery were included in predictors of closure analyses (n=1,274). Small bladder size (adjusted RR 1.57, 95% CI 1.39-1.79), prior repair (adjusted RR 1.40, 95% CI 1.11-1.76), severe vaginal scarring (adjusted RR 1.56, 95% CI 1.20-2.04), partial urethral involvement (adjusted RR 1.36, 95% CI 1.11-1.66), and complete urethral destruction or circumferential defect (adjusted RR 1.72, 95% CI 1.33-2.23) predicted failed fistula closure. Women with a closed fistula at 3-month follow-up were included in predictors of residual incontinence analyses (n=1,041). Prior repair (adjusted RR 1.37, 95% CI 1.13-1.65), severe vaginal scarring (adjusted RR 1.35, 95% CI 1.10-1.67), partial urethral involvement (adjusted RR 1.78, 95% CI 1.27-2.48), and complete urethral destruction or circumferential defect (adjusted RR 2.06, 95% CI 1.51-2.81) were significantly associated with residual incontinence. CONCLUSION:: The prognosis for genital fistula closure is related to preoperative bladder size, previous repair, vaginal scarring, and urethral involvement. LEVEL OF EVIDENCE:: II. 相似文献

Men have lower rates of HIV testing and higher rates of AIDS-related mortality compared to women in sub-Saharan Africa. To assess whether there is an opportunity to increase men’s uptake of testing by correcting misperceptions about testing norms, we compare men’s perceptions of their closest friend’s HIV testing behaviors with the friend’s actual testing self-report using a unique dataset of men sampled within their social networks (n = 59) in Dar es Salaam, Tanzania. We examine the accuracy and bias of perceptions among men who have tested for HIV (n = 391) and compare them to the perceptions among men who never tested (n = 432). We found that testers and non-testers did not differ in the accuracy of their perceptions, though non-testers were strongly biased towards assuming that their closest friends had not tested. Our results lend support to social norms approaches designed to correct the biased misperceptions of non-testers to promote men’s HIV testing. 相似文献

Left atrial leiomyosarcoma is an uncommon entity and accounts for 0.25 % of all cardiac tumors. Though long term survival is a rarity, surgical excision of the tumor helps in prolonging life. Its diagnosis is almost always confirmed on histopathology. We report a 72 years old male who presented with severe dyspnoea. A diagnosis of left atrial myxoma was made before surgery. The tumor was found to occupy the whole of the left atrial cavity and extended into left pulmonary vein. The left atrial tumor mass was excised along with the left atrial wall but due to his advanced age and severe pulmonary hypertension no attempt was made to do a left pneumonectomy. 相似文献
