Interventions in sexual and reproductive health services addressing violence against women in low-income and middle-income countries: a mixed-methods systematic review.

OBJECTIVES: To synthesise evidence on the effectiveness, cost-effectiveness and barriers to responding to violence against women (VAW) in sexual and reproductive health (SRH) services in low/middle-income countries (LMICs). DESIGN: Mixed-methods systematic review. DATA SOURCES: Medline, Embase, Psycinfo, Cochrane, Cinahl, IMEMR, Web of Science, Popline, Lilacs, WHO RHL, ClinicalTrials.gov, Google, Google Scholar, websites of key organisations through December 2019. ELIGIBILITY CRITERIA: Studies of any design that evaluated VAW interventions in SRH services in LMICs. DATA EXTRACTION AND SYNTHESIS: Concurrent narrative quantitative and thematic qualitative syntheses, integration through line of argument and mapping onto a logic model. Two reviewers extracted data and appraised quality. RESULTS: 26 studies of varied interventions using heterogeneous outcomes. Of ten interventions that strengthened health systems capacity to respond to VAW during routine SRH consultation, three reported no harm and reduction in some types of violence. Of nine interventions that strengthened health systems and communities' capacity to respond to VAW, three reported conflicting effects on re-exposure to some types of VAW and mixed effect on SRH. The interventions increased identification of VAW but had no effect on the provision (75%-100%) and uptake (0.6%-53%) of referrals to VAW services. Of seven psychosocial interventions in addition to SRH consultation that strengthened women's readiness to address VAW, four reduced re-exposure to some types of VAW and improved health. Factors that disrupted the pathway to better outcomes included accepting attitudes towards VAW, fear of consequences and limited readiness of the society, health systems and individuals. No study evaluated cost-effectiveness. CONCLUSIONS: Some VAW interventions in SRH services reduced re-exposure to some types of VAW and improved some health outcomes in single studies. Future interventions should strengthen capacity to address VAW across health systems, communities and individual women. First-line support should be better tailored to women's needs and expectations.

HBV/HDV co-infection in the Western Brazilian Amazonia: an intriguing mutation among HDV genotype 3 carriers.

HDV infection still remains a serious public health problem in Amazonia. There are few data regarding the biomolecular aspects of HBV/HDV co-infection in this region. We studied 92 patients HBsAg(+) /anti-HDV IgG(+) followed at the Hepatitis Referral Centers of Porto Velho (RO), Rio Branco and Cruzeiro do Sul (AC), Brazil, from March 2006 to March 2007 for whom the HDV and/or the HBV genotype could be determined. The HDV genotype could be determined in 90 patients, while the HBV genotypes could be positively determined in 74. HBV subgenotype F2 is the most prevalent (40.2%), followed by the subgenotypes A1 (15.2%) and D3 (8.7%), while 16.4% were other subgenotypes or genotypes, 4.3% were discordant and 15.2% were unamplifiable. Surprisingly, HDV genotype 3 (HDV-3) was found in all of the HBV/HDV-infected patients that could be genotyped for HDV, confirming that HDV-3 can associate with non-F HBV genotypes. However, a HDV-3 mutant was found in 29.3% of patients and was more frequently associated with non-F HBV genotypes (P < 0.001) than were nonmutant strains, suggesting that the mutation may facilitate association of HDV-3 with non-F HBV genotypes.

Characteristics and survival of HIV-infected patients not screened for hepatitis C virus infection in a hospital-based cohort.

The rate of human immunodeficiency virus (HIV) disease progression or death of individuals coinfected with hepatitis C virus (HCV) is conflicting. The complete-case analysis systematically used, excludes patients unscreened for HCV. Our objective was to assess if rate of survival differed between HIV-infected patients screened and unscreened for HCV in a hospital-based prospective cohort study. Patients were enrolled in the Lyon section of the French Hospital Database on HIV between 1 July 1992 and 31 May 2005. A multivariate Cox regression model was used to analyse the association of HCV screening with survival. Of 3244 patients, 299 (9.2%) were not screened for HCV. The populations screened and unscreened differed by the proportion of acquired immune deficiency syndrome at baseline, presumed route of infection, CD4 cell count category at baseline, mean duration of follow-up, mean number of visits per year, type of antiretroviral therapy and survival. The rate of progression to death was higher for non-HCV-screened vs HCV-screened patients: the incidence rate among HCV-screened patients was 22.9/1000 patient-years; the incidence rate among HCV-unscreened patients was 52.4/1000 patient-years. The adjusted hazards ratio of death was 2.48 [95% confidence interval (1.83-3.35); P < 0.001] for patients with unknown HCV status compared with others. In conclusion, unscreened or unknown HCV status was associated with an increased risk of death in our hospital cohort. Important prognostic factors are related to, or confounded by the practice of HCV screening.

Prevalence and sexual risk of hepatitis C virus infection when human immunodeficiency virus was acquired through sexual intercourse among patients of the Lyon University Hospitals, France, 1992-2002.

To report the prevalence and the risk factors for hepatitis C virus (HCV) infection in a hospital cohort of 2691 sexually human immunodeficiency virus (HIV)-infected patients. The patients were enrolled in the Lyon section of the French Hospital Database on HIV between 1992 and 2002. Baseline characteristics were analysed. The detection of HCV-antibodies (Ab) was used for diagnosis. The HCV-Ab prevalence rate was 5.7 and 12.89% for individuals infected by HIV after homosexual intercourse or heterosexual intercourse, respectively. HCV-Ab was three times more frequently found among patients infected with HIV after heterosexual intercourse compared with patients infected with HIV after homosexual intercourse (adjusted OR: 3.2, 95% CI: 2.28-4.62, multiple logistic regression). The risk of HCV infection among HIV-infected individuals differed according to sexual behaviour. The determinants associated with HCV transmission through the sexual route needs to be explored further.

Dalitz plot analysis of the decay D(+)-->K(-)pi(+)pi(+) and indication of a low-mass scalar Kpi resonance.

We study the Dalitz plot of the decay D(+)-->K(-)pi(+)pi(+) with a sample of 15090 events from Fermilab experiment E791. Modeling the decay amplitude as the coherent sum of known Kpi resonances and a uniform nonresonant term, we do not obtain an acceptable fit. If we allow the mass and width of the K(*)(0)(1430) to float, we obtain values consistent with those from PDG but the chi(2) per degree of freedom of the fit is still unsatisfactory. A good fit is found when we allow for the presence of an additional scalar resonance, with mass 797+/-19+/-43 MeV/c(2) and width 410+/-43+/-87 MeV/c(2). The mass and width of the K(*)(0)(1430) become 1459+/-7+/-5 MeV/c(2) and 175+/-12+/-12 MeV/c(2), respectively. Our results provide new information on the scalar sector in hadron spectroscopy.

IgG anti-IgE autoantibodies in visceral leishmaniasis.

Procedures for IgG depletion in visceral leishmaniasis (VL) and schistosomiasis sera using Sepharose-protein G beads also deplete IgE. In this study, the presence of IgG anti-IgE autoantibodies in sera from patients with VL (n = 10), and hepatic-intestinal schistosomiasis (n = 10) and from healthy individuals (n = 10) was investigated. A sandwich ELISA using goat IgG anti-human IgE to capture serum IgE and goat anti-human IgG peroxidase conjugate to demonstrate the binding of IgG to the IgE captured was performed. VL sera had higher titers (p < 0.05) of IgG anti-IgE autoantibodies (OD = 2.01 +/- 0.43) than sera from healthy individuals (OD = 1.35 +/- 0.16) or persons infected with Schistosoma mansoni (OD = 1.34 +/- 0.18). The immunoblotting carried out with eluates from Sepharose-protein G beads used to deplete IgG from these sera and goat anti-human IgE peroxidase conjugate, showed a similar pattern of bands, predominating the 75 kDa epsilon-heavy chain and also polypeptides resulting from physiological enzymatic digestion of IgE. A frequent additional band immediately above 75 kDa was observed only in VL sera.

Direct measurement of the pion valence-quark momentum distribution, the pion light-cone wave function squared.

We present the first direct measurements of the pion valence-quark momentum distribution which is related to the square of the pion light-cone wave function. The measurements were carried out using data on diffractive dissociation of 500 GeV/c pi(-) into dijets from a platinum target at Fermilab experiment E791. The results show that the /q&q> light-cone asymptotic wave function describes the data well for Q2 approximately 10 (GeV/c)(2) or more. We also measured the transverse momentum distribution of the diffractive dijets.

Observation of color-transparency in diffractive dissociation of pions.

We have studied the diffractive dissociation into dijets of 500 GeV/c pions scattering coherently from carbon and platinum targets. Extrapolating to asymptotically high energies (where t(min)-->0), we find that when the per-nucleus cross section for this process is parametrized as sigma = sigma0Aalpha, alpha has values near 1.6, the exact result depending on jet transverse momentum. These values are in agreement with those predicted by theoretical calculations of color-transparency.

Search for rare and forbidden Charm Meson decays D0 --> Vl+l- and hhll.

We report results of a search for flavor-changing neutral current (FCNC), lepton flavor, and lepton-number violating decays of the D0 (and its antiparticle) into three and four bodies. Using data from Fermilab charm hadroproduction experiment E791, we examine modes with two leptons (muons or electrons) and a rho(0), K( *0), or straight phi vector meson or a nonresonant pi(pi), Kpi, or KK pair of pseudoscalar mesons. No evidence for any of these decays is found. Therefore, we present branching-fraction upper limits at 90% confidence level for the 27 decay modes examined (18 new).

Study of the D(+)(s)-->pi(-)pi(+)pi(+) decay and measurement of f(0) masses and widths.

From a sample of 848+/-44 D(+)(s)-->pi(-)pi(+)pi(+) decays, we find gamma(D(+)(s)-->pi(-)pi(+)pi(+))/gamma(D(+)(s)-->straight phipi(+)) = 0.245+/-0.028(+0.019)(-0.012). Using a Dalitz plot analysis of this three body decay, we find significant contributions from the channels rho(0)(770)pi(+), rho(0)(1450)pi(+), f(0)(980)pi(+), f(2)(1270)pi(+), and f(0)(1370)pi(+). We also present the values obtained for masses and widths of the resonances f(0)(980) and f(0)(1370).

Experimental evidence for a light and broad scalar resonance in D(+) --> pi(-)pi(+)pi(+) decay.

From a sample of 1172 +/- 61 D(+)-->pi(-)pi(+)pi(+) decays, we find gamma(D(+)-->pi(-)pi(+)pi(+))/gamma(D(+)-->K-pi(+)pi(+)) = 0.0311 +/- 0.0018(+0.0016)(-0.0026). Using a coherent amplitude analysis to fit the Dalitz plot of these decays, we find strong evidence that a scalar resonance of mass 478(+24)(-23) +/- 17 MeV/c(2) and width 324(+42)(-40) +/- 21 MeV/c(2) accounts for approximately half of all decays.

IL-10 and IL-12 are the main regulatory cytokines in visceral leishmaniasis.

Visceral leishmaniasis (VL) is characterized by the absence of cytokines such as IFN-gamma and IL-12. Cure of VL is associated with a restoration of the ability to make these cytokines. The aim of the present study was to evaluate the role of IL-12 in the recovery of the ability to produce IFN-gamma and to test whether or not IL-4 IL-10 and/or TGF-beta could suppress IFN-gamma production by PBMC from treated VL patients. High stimulation index (SI) of proliferation was observed in PBMC from subjects stimulated with Leishmania chagasi antigen (181+/-83). Neutralizing IL-12 inhibited lymphoproliferation [stimulation index (SI) of 210+/-114 to 1+/-0.6 (P<0.01)] and/or the production of IFN-gamma [2792+/-402 pg/ml to 407+/-449 pg/ml (P<0.01)]. Recombinant IL-10 abrogated the lymphoproliferation (SI=2+/-3) while recombinant IL-4 or TGF-beta had no effect on this response (147+/-22 and 194+/-12 respectively). IFN-gamma was high when PBMCs were stimulated with L. chagasi (873+/-400 pg/ml) and this was abrogated by the addition of IL-10 (5+/-2 pg/ml). In contrast neither IL-4 or TGF-beta suppressed IFN-gamma production (837+/-244 pg/ml and 759+/-523 pg/ml). These results indicate that IL-12 plays an important role in the ability of treated VL patients to make IFN-gamma and that IL-10 but not IL-4 or TGF-beta inhibits this response.

Randomized, double-blind study of stibogluconate plus human granulocyte macrophage colony-stimulating factor versus stibogluconate alone in the treatment of cutaneous Leishmaniasis.

The response to recombinant human granulocyte macrophage colony-stimulating factor (GM-CSF) in the treatment of cutaneous leishmaniasis was evaluated. Twenty patients with cutaneous leishmaniasis who had lesions for 60 days were enrolled in a double-blind placebo trial of GM-CSF with standard parenteral sodium stibogluconate (20 mg/kg-1/day-1) for 20 days. Ten patients were randomized to receive intralesionally injected GM-CSF (200 microgram) at enrollment and 1 week after, and 10 patients received saline as placebo. GM-CSF- and antimony-treated patients healed faster than patients who received antimony alone (49+/-32.8 vs. 110+/-61.6 days, P<.05). Seven of 10 patients were healed of their lesions before 40 days after therapy in the GM-CSF group, compared with only 1 of 10 patients in the placebo group (relative risk, 7; 95% confidence interval, 1.04-47.00). Thus, GM-CSF plus antimony significantly increased the chance of lesion healing in 40 days.

T cell response of asymptomatic Leishmania chagasi infected subjects to recombinant leishmania antigens.

In areas of Leishmania chagasi transmission the ability to control leishmania infection is associated with IFN-gamma production. In visceral leishmaniasis down-regulation of T cell responses is mediated by interleukin-10 (IL-10). In this study we evaluated the lymphoproliferative response, IFN-gamma and IL-10 production on lymphocyte cultures stimulated with recombinant leishmania antigens in subjects with asymptomatic L. chagasi infection. There was a statistically significant difference in the lymphoproliferative response of the subjects with asymptomatic infection as compared to patients with visceral leishmaniasis and healthy subjects with respect to crude antigens (p<0.01), gp-63 (p<0.05) and hsp-70 (p<0. 01), as well as between asymptomatic L. chagasi infected subjects and patients with visceral leishmaniasis with respect to the response to all antigens tested. The IFN-gamma production observed in the group with asymptomatic infection with all the three recombinant antigens tested was higher (p<0.01) than that observed in patients with visceral leishmaniasis and in healthy subjects. Furthermore, in individuals with asymptomatic infection, IL-10 levels in cultures stimulated with recombinant antigens were very low. This study shows that lymphocytes from individuals with asymptomatic L. chagasi infection are able to recognize recombinant leishmania antigens with production of a cytokine that is associated with leishmania killing.

Gender violence and reproductive health.

The available literature reflects the growing interest in gender violence and reproductive health. Violence is generally studied by identifying pathologies, measuring their demands on services and evaluating their repercussions on fetal outcome. Institutional violence, however, has received little attention and is mainly concerned with the consequences of inappropriate use of technologies. Data from the Sexuality and Health Feminist Collective shows that among patients, 20.5% stated that they have never talked about their sexual life with their partners; 38.3% stated that they have had sexual intercourse against their will, including situations ranging from sexual harassment to rape which was referred by 12.3% of them. One of the most relevant issues arising from the anamnesis and interviews of these women was the violence to which they were submitted by health services. The high prevalence of violent situations indicates the urgency of incorporating an approach which deals with gender violence and promotes the empowerment of women into the routine of reproductive health services.
