1. Title: Effectiveness of a community-based intervention to improve nutrition in young children in Senegal: a difference in difference analysis. Author: Alderman H; Ndiaye B; Linnemayr S; Ka A; Rokx C; Dieng K; Mulder-Sibanda M Source: Public Health Nutrition. 2009 May;12(5):667-73. Abstract: There are few studies of community growth promotion as a means of addressing malnutrition that are based on longitudinal analysis of large-scale programmes with adequate controls to construct a counterfactual. The current study uses a difference in difference comparison of cohorts to assess the impact on the proportion of underweight children who lived in villages receiving services provided by the Senegal Nutrition Enhancement Project between 2004 and 2006. The project, designed to extend nutrition and growth promotion intervention into rural areas through non-governmental organisation service providers, significantly lowered the risk of a child having a weight more than 2 sd below international norms. The odds ratio of being underweight for children in programme villages after introduction of the intervention was 0.83 (95% CI 0.686, 1.000), after controlling for regional trends and village and household characteristics. Most measured aspects of health care and health seeking behaviour improved in the treatment relative to the control.

2. Title: Reproductive and hormonal factors, and ovarian cancer risk for BRCA1 and BRCA2 mutation carriers: results from the International BRCA1/2 Carrier Cohort Study. Author: Antoniou AC; Rookus M; Andrieu N; Brohet R; Chang-Claude J Source: Cancer Epidemiology, Biomarkers and Prevention. 2009 Feb;18(2):601-10. Abstract: BACKGROUND: Several reproductive and hormonal factors are known to be associated with ovarian cancer risk in the general population, including parity and oral contraceptive (OC) use. However, their effect on ovarian cancer risk for BRCA1 and BRCA2 mutation carriers has only been investigated in a small number of studies. METHODS: We used data on 2,281 BRCA1 carriers and 1,038 BRCA2 carriers from the International BRCA1/2 Carrier Cohort Study to evaluate the effect of reproductive and hormonal factors on ovarian cancer risk for mutation carriers. Data were analyzed within a weighted Cox proportional hazards framework. RESULTS: There were no significant differences in the risk of ovarian cancer between parous and nulliparous carriers. For parous BRCA1 mutation carriers, the risk of ovarian cancer was reduced with each additional full-term pregnancy (P trend = 0.002). BRCA1 carriers who had ever used OC were at a significantly reduced risk of developing ovarian cancer (hazard ratio, 0.52; 95% confidence intervals, 0.37-0.73; P = 0.0002) and increasing duration of OC use was associated with a reduced ovarian cancer risk (P trend = 0.0004). The protective effect of OC use for BRCA1 mutation carriers seemed to be greater among more recent users. Tubal ligation was associated with a reduced risk of ovarian cancer for BRCA1 carriers (hazard ratio, 0.42; 95% confidence intervals, 0.22-0.80; P = 0.008). The number of ovarian cancer cases in BRCA2 mutation carriers was too small to draw definitive conclusions. CONCLUSIONS: The results provide further confirmation that OC use, number of full-term pregnancies, and tubal ligation are associated with ovarian cancer risk in BRCA1 carriers to a similar relative extent as in the general population.

3. Peer Reviewed Title: High human herpesvirus 8 (HHV-8) prevalence, clinical correlates and high incidence among recently HIV-1-infected subjects in Sao Paulo, Brazil. Author: Batista MD; Ferreira S; Sauer MM; Tomiyama H; Giret MT; Pannuti CS; Diaz RS; Sabino EC; Kallas EG Source: PloS One. 2009;4(5):e5613. Abstract: BACKGROUND: Human herpesvirus 8 (HHV-8) is the etiological agent for Kaposi Sarcoma, which occurs especially in HIV-infected subjects. HHV-8 infection and its clinical correlates have not been well characterized in recently HIV-1-infected subjects, especially men who have sex with men (MSM). METHODOLOGY/ PRINCIPAL FINDINGS: We assessed the HHV-8 seroprevalence, clinical correlates, and incidence after one year of follow-up in a cohort of 228 recently HIV-1-infected individuals, of whom 83.6% were MSM, using indirect immunofluorescence assay. The prevalence of HHV-8 infection at the time of cohort enrollment was 25.9% (59/228). In the univariate model, there were significant associations with male gender, black ethnicity, MSM practice, and previous hepatitis B virus and syphilis infections. In the multivariate model we could still demonstrate association with MSM, hepatitis B, and black ethnicity. No differences in mean CD4+ cell counts or HIV viral load according to HHV-8 status were found. In terms of incidence, there were 23/127 (18.1%) seroconversions in the cohort after 1 year. CONCLUSIONS: HHV-8 is highly prevalent among recently HIV-1-infected subjects. Correlations with other sexually transmitted infections suggest common transmission routes.

4. Peer Reviewed Title: The intergenerational impact of the African orphans crisis: a cohort study from an HIV/AIDS affected area. Author: Beegle K; De Weerdt J; Dercon S Source: International Journal of Epidemiology. 2009 Apr;38(2):561-8. Abstract: BACKGROUND: In sub-Saharan Africa, the prevalence of orphanhood among children has been greatly exacerbated by the HIV/AIDS pandemic. If orphanhood harms a child's development and these effects perpetuate into adult life, then the African orphan crisis could seriously jeopardize the continent's future generations. Whether or not there exists an adverse, causal and intergenerational effect of HIV/AIDS on development is of crucial importance for setting medical priorities. This study is the first to empirically investigate the impact of orphanhood on health and schooling using long-term longitudinal data following children into adulthood. METHODS: We examined a cohort of 718 children interviewed in the early 1990s and again in 2004. Detailed survey questionnaires and anthropometric measurements were administered at baseline and during a follow-up survey. Final attained height and education (at adulthood) between children who lost a parent before the age of 15 and those who did not were compared. RESULTS: On average, children who lose their mother before the age of 15 suffer a deficit of around 2 cm in final attained height (mean 1.96; 95% CI 0.06-3.77) and 1 year of final attained schooling (mean 1.01; 95% CI 0.39-1.81). This effect is permanent and the hypothesis that it is causal cannot be rejected by our study. Although father's death is a predictor of lower height and schooling as well, we reject the hypothesis of a causal link. CONCLUSIONS: The African orphan crisis, exacerbated by the HIV/AIDS epidemic will have important negative intergenerational effects.

5. Peer Reviewed Title: Bone mineral density in a cohort of adolescents during use of norethisterone enanthate, depot-medroxyprogesterone acetate or combined oral contraceptives and after discontinuation of norethisterone enanthate. Author: Beksinska ME; Kleinschmidt I; Smit JA; Farley TM Source: Contraception. 2009 May;79(5):345-9. Abstract: BACKGROUND: Depot medroxyprogesterone acetate (DMPA), norethisterone enanthate (NET-EN) and combined oral contraceptives (COCs) have been shown to have a negative effect on bone mineral density (BMD) in adolescents. The aim of this study was to investigate BMD in 15- to 19-year-old new users of DMPA, NET-EN and COCs. STUDY DESIGN: This 5-year longitudinal study followed up new users of DMPA (n=115), NET-EN (n=115) and COCs (n=116) and 144 nonuser controls. BMD was measured at the distal radius using dual-energy X-ray absorptiometry. RESULTS: BMD increased in all groups (annual percent increase: nonusers, 1.49%; DMPA, 1.39%; NET-EN, 1.03%; COCs, 0.84%) during follow-up (p<.001). There was evidence for lower BMD increases per annum in NET-EN (p=.050) and COC (p=.010) users compared to nonusers but no difference between DMPA and nonusers (p=.76). In 14 NET-EN discontinuers, an overall reduction of 0.61% per year BMD was followed upon cessation by an increase of 0.69% per year (p=.066). CONCLUSION: This study suggests that BMD increases in adolescents may be less in NET-EN and COC users; however, recovery of BMD in NET-EN users was found in the small sample of adolescents followed post-discontinuation.

Author: Ben Hamouda I; Mrabet A Source: La Tunisie Medicale. 2009 Mar;87(3):169-72. Abstract: AIM: Development on the epileptic women's care. METHOD: A research in the medical literature on PubMed and an exhaustive review of the published summaries and reports of Epileptology International Meetings, in the last five years. We included cohort studies, reviews and randomized double blinded therapeutic trials. Case reports and fundamental research studies have been excluded. RESULTS: sensitizing of the epileptic women starts with adolescence with an education and a preparation to sexual life and available contraceptive methods, in order to avoid undesired pregnancies and the serious consequences which they are likely to generate. Approximately 1/3 of the epileptic women have variations of their disease related to the menstrual cycle, probably because of a neurotoxic effect of estrogens (not counterbalanced by progestational hormones). Antiepileptic teratogenicity issue is not, yet, solved, in spite of new molecules commercialisation. The upkeep of a register concerning the use of AED during pregnancy makes it possible to better identify the problems and to establish an optimal therapeutic control for the mother and the child. CONCLUSION: Epilepsy impact on women's life is very different compared to men, because it interferes with the fields of sexuality, reproduction, menstrual cycle and contraception, in addition of AED teratogenicity. A close cooperation between obstetricians and neurologist and a sensitizing of health professionals are essential for the global care of the epileptic pregnant women or in age of procreation.

Abstract: BACKGROUND: GB virus C (GBV-C) is an apathogenic virus that inhibits human immunodeficiency virus (HIV) replication in vitro. Mother-to-child transmission (MTCT) of GBV-C has been observed in multiple small studies. Our study examined the rate and correlates of MTCT of GBV-C in a large cohort of GBV-C-HIV-coinfected pregnant women in Thailand. METHODS: Maternal delivery plasma specimens from 245 GBV-C-HIV-infected women and specimens from their infants at 4 or 6 months of age were tested for GBV-C RNA. Associations with MTCT of GBV-C were examined using logistic regression. RESULTS: One hundred one (41%) of 245 infants acquired GBV-C infection. MTCT of GBV-C was independently associated with maternal antiretroviral therapy (adjusted odds ratio [AOR], 5.21 [95% confidence interval {CI}, 2.12-12.81]), infant HIV infection (AOR, 0.05 [95% CI, 0.01-0.26]), maternal GBV-C load (8.0 log(10) copies/mL: AOR, 86.77 [95% CI, 15.27-481.70]; 7.0-7.9 log(10) copies/mL: AOR, 45.62 [95% CI, 8.41-247.51]; 5.0-6.9 log(10) copies/mL: AOR, 9.07 [95% CI, 1.85-44.33]: reference, <5 log(10) viral copies/mL), and caesarean delivery (AOR, 0.26 [95% CI, 0.12-0.59]). CONCLUSIONS: Associations with maternal GBV-C load and mode of delivery suggest transmission during pregnancy and delivery. Despite mode of delivery being a common risk factor for virus transmission, GBV-C and HIV were rarely cotransmitted. The mechanisms by which maternal receipt of antiretroviral therapy might increase MTCT of GBV-C are unknown.

8. Peer Reviewed Title: Is sexual risk taking behaviour changing in rural south-west Uganda? Behaviour trends in a rural population cohort 1993 2006. Author: Biraro S; Shafer LA; Kleinschmidt I; Wolff B; Karabalinda A; Nalwoga A; Musinguzi J; Kirungi W; Opio A; Whitworth J; Grosskurth H Source: Sexually Transmitted Infections. 2009 Apr;85(Suppl 1):i3-i11. Abstract: Objective: To describe sexual behaviour trends in a rural Ugandan cohort in the context of an evolving HIV epidemic, 1993-2006. Methods: Sexual behaviour data were collected annually from a population cohort in which HIV serological surveys were also conducted. Behaviour trends were determined using survival analysis and logistic regression. Trends are reported based on the years in which the respective indicators were collected. Results: Between 1993 and 2006, median age at first sex increased from 16.7 years to 18.2 years among 17-20-year-old girls and from 18.5 years to 19.9 years among boys. Both sexes reported a dip in age at sexual debut between 1998 and 2001. One or more casual partners in the past 12 months among men rose from 11.6% in 1997 to 12.7% in 2004 and then declined to 10.2% in 2006. Among women it increased from 1.4% in 1997 to 3.7% in 2004 and then reduced to 1.4% in 2006. The rise in casual partners between 1997 and 2004 was driven mainly by older age groups. Trends in condom use with casual partners varied by age, increasing among those aged 35+ years, declining in the middle age groups and presenting a dip and then a rise in the youngest aged group (13-19 years). Conclusion: Among youth, risky behaviour declined but increased in the late 1990s/early 2000s. Among those aged 35+ years, condom use rose but casual partners also rose. Several indicators portrayed a temporary increase in risk taking behaviour from 1998 to 2002.

Author: Blanco-Munoz J; Torres-Sanchez L; Lopez-Carrillo L Source: Public Health Reports. 2009 Mar-Apr;124(2):317-22. Abstract: Conclusive evidence shows that maternal tobacco consumption increases the risk of infertility, subfertility, ectopic pregnancy, preterm birth, low birthweight, and stillbirth. Nevertheless, evidence with respect to the risk of spontaneous abortion (SA) (i.e., miscarriage) is inconsistent. In a case-control study, Kline et al. identified an increase in miscarriages in women who were smokers. In Canadian women, Armstrong et al. found a 20% increase in the risk of SA for every 10 cigarettes consumed daily. Other authors have also shown a positive association between cotinine levels in urine and SA. On the other hand, in Rasch's study, after adjusting for other risk factors, women who smoked 10 to 19 cigarettes and 20 or more cigarettes per day did not have significantly increased odds ratios (ORs) for having SAs. The role of paternal tobacco exposure in adverse reproductive effects has been scarcely evaluated. Some reports in the literature assert that tobacco consumption in men is associated with morphological alterations in sperm, a decrease in sperm density and motility, and a reduction in semen volume,11 which could have implications for male fertility and embryo viability. However, the scarce studies that to date have evaluated the association between exposure to paternal tobacco and SA are also contradictory.

10. Peer Reviewed Title: Comparison of CD4 cell count, viral load, and other markers for the prediction of mortality among HIV-1-infected Kenyan pregnant women. Author: Brown ER; Otieno P; Mbori-Ngacha DA; Farquhar C; Obimbo EM; Nduati R; Overbaugh J; John-Stewart GC Source: Journal of Infectious Diseases. 2009 May 1;199(9):1292-300. Abstract: BACKGROUND: There are limited data regarding the relative merits of biomarkers as predictors of mortality or time to initiation of antiretroviral therapy (ART). METHODS: We evaluated the usefulness of the CD4 cell count, CD4 cell percentage (CD4%), human immunodeficiency virus type 1 (HIV-1) load, total lymphocyte count (TLC), body mass index (BMI), and hemoglobin measured at 32 weeks' gestation as predictors of mortality in a cohort of HIV-1-infected women in Nairobi, Kenya. Sensitivity, specificity, positive predictive value (PPV), and area under the receiver operating characteristic (ROC) curve (AUC) were determined for each biomarker separately, as well as for the CD4 cell count and the HIV-1 load combined. RESULTS: Among 489 women with 10,150 person-months of follow-up, mortality rates at 1 and 2 years postpartum were 2.1% (95% confidence interval [CI], 0.7%-3.4%) and 5.5% (95% CI, 3.0%-8.0%), respectively. CD4 cell count and CD4% had the highest AUC value (>0.9). BMI, TLC, and hemoglobin were each associated with but poorly predictive of mortality (PPV, <7%). The HIV-1 load did not predict mortality beyond the CD4 cell count. CONCLUSIONS: The CD4 cell count and CD4% measured during pregnancy were both useful predictors of mortality among pregnant women. TLC, BMI, and hemoglobin had a limited predictive value, and the HIV-1 load did not predict mortality any better than did the CD4 cell count alone.

11. Peer Reviewed Title: The "seeded" focus group: a strategy to recruit HIV+ community members into treatment research. Author: Busza J; Zaba B; Urassa M Source: Sexually Transmitted Infections. 2009 Jun;85(3):212-5. Abstract: OBJECTIVE(S): We piloted an innovative community-based recruitment approach to contact known HIV+ individuals for referral to treatment without endangering their confidentiality. METHODS: Nested within an HIV cohort study, operations research to monitor and improve rural uptake of antiretroviral therapy (ART) was conducted alongside the introduction of Tanzania's national treatment programme. We confronted the challenge of recruiting participants without inadvertently disclosing their HIV status to family or other community members. During post-test counselling, nurses compiled a list of HIV+ persons who expressed interest in being contacted when ART became available. Study numbers, but not names, of 12 "seeds" were added to a randomly generated list of residents, matched by age group and sex, and all were invited to participate in focus-group discussions on community perceptions of treatment. After the discussion, the original counsellors met each participant in private, inviting the "seed" for ART referral and offering VCT to others. RESULTS: Ten "seeds" were successfully located and attended the local focus-group discussion; all subsequently volunteered to undergo clinical tests in advance of receiving antiretroviral therapy. They also agreed to participate in a study of barriers to ART access. The other focus-group members contributed useful information on levels of understanding and support for treatment, and several came forward for HIV testing. CONCLUSIONS: The "seeded" focus group is a very straightforward and easily arranged method of recruiting HIV+ people for research or service delivery within a wider context of engaging with local community perceptions.

12. Peer Reviewed Title: Two-year virologic outcomes of an alternative AIDS care model: evaluation of a peer health worker and nurse-staffed community-based program in Uganda. Author: Chang LW; Alamo S; Guma S; Christopher J; Suntoke T; Omasete R; Montis JP; Quinn TC; Juncker M; Reynolds SJ Source: Journal of Acquired Immune Deficiency Syndromes. 2009 Mar 1;50(3):276-82. Abstract: BACKGROUND: There is growing concern about the human resources needed to care for increasing numbers of patients receiving antiretroviral therapy in resource-limited settings. We evaluated an alternative model, community-based, comprehensive antiretroviral program staffed primarily by peer health workers and nurses. METHODS: We conducted a retrospective cohort study of patients receiving antiretroviral therapy during the first 10 months of program enrollment beginning in late 2003. Virologic, immunologic, clinical, and adherence data were collected. RESULTS: Of 360 patients started on treatment, 258 (72%) were active and on therapy approximately 2 years later. Viral load testing demonstrated that 86% of active patients (211/246 tested) had a viral load <400 copies per milliliter. The median CD4 increase for active patients was 197 cells per cubic millimeter (interquartile range, 108-346). Patients with either a history of antiretroviral use or lack of CD4 response were more likely to experience virologic failure. Survival was 84% at 1 year and 82% at 2 years. World Health Organization stage 4 was predictive of both not sustaining therapy and increased mortality. CONCLUSIONS: A community-based antiretroviral treatment program in a resource-limited setting can provide excellent AIDS care over at least a 2-year period. A comprehensive program based upon peer health workers and nurses provides an effective alternative model for AIDS care.

13. Title: Recent oral contraceptive use and adverse birth outcomes. Author: Chen XK; Wen SW; Sun LM; Yang Q; Walker MC Source: European Journal of Obstetrics, Gynecology, and Reproductive Biology. 2009;144:40-43. Abstract: OBJECTIVE: To examine the possible association between oral contraceptive use and adverse birth outcomes. STUDY DESIGN: We conducted a population-based cohort study of pregnant women who used oral contraceptives within 3 months before their last menstrual period. Subjects were divided into three groups, according to the interval (0-30, 31-60, and 61-90 days) between the dispensing date and their last menstrual period. For each exposed subject, 4 subjects without exposure to oral contraceptives were individually matched by infant's year of birth and plurality and by mother's age and parity. RESULTS: Oral contraceptive use within 30 days prior to the last menstrual period was associated with increased risks of very low birth weight (OR: 3.24, 95% CI: 1.18, 8.92), low birth weight (OR: 1.93, 95% CI: 1.17, 3.20), and preterm birth (OR: 1.61, 95% CI: 1.01, 2.55); however, oral contraceptive use 31-90 days prior to the last menstrual period did not increase the risk of low birth weight or preterm birth.CONCLUSION: Our results indicate the use of oral contraceptives near the time of conception may be associated with an increased risk of low birth weight and preterm birth.

14. Peer Reviewed Title: Adherence to first-line antiretroviral therapy affects non-virologic outcomes among patients on treatment for more than 12 months in Lusaka, Zambia. Author: Chi BH; Cantrell RA; Zulu I; Mulenga LB; Levy JW; Tambatamba BC; Reid S; Mwango A; Mwinga A; Bulterys M; Saag MS; Stringer JS Source: International Journal of Epidemiology. 2009 Jun;38(3):746-56. Abstract: BACKGROUND: High-level adherence to antiretroviral therapy (ART) is associated with favourable patient outcomes. In resource-constrained settings, however, there are few validated measures. We examined the correlation between clinical outcomes and the medication possession ratio (MPR), a pharmacy-based measure of adherence. METHODS: We analysed data from a large programmatic cohort across 18 primary care centres providing ART in Lusaka, Zambia. Patients were stratified into three categories based on MPR-calculated adherence over the first 12 months: optimal (> or =95%), suboptimal (80-94%) and poor (<80%). RESULTS: Overall, 27 115 treatment-naive adults initiated and continued ART for > or =12 months: 17 060 (62.9%) demonstrated optimal adherence, 7682 (28.3%) had suboptimal adherence and 2373 (8.8%) had poor adherence. When compared with those with optimal adherence, post-12-month mortality risk was similar among patients with sub-optimal adherence [adjusted hazard ratio (AHR) = 1.0; 95% CI: 0.9-1.2] but higher in patients with poor adherence (AHR = 1.7; 95% CI: 1.4-2.2). Those <80% MPR also appeared to have an attenuated CD4 response at 18 months (185 cells/microl vs 217 cells/microl; P < 0.001), 24 months (213 cells/microl vs 246 cells/microl; P < 0.001), 30 months (226 cells/microl vs 261 cells/microl; P < 0.001) and 36 months (245 cells/microl vs 275 cells/microl; P < 0.01) when compared with those above this threshold. CONCLUSIONS: MPR was predictive of clinical outcomes and immunologic response in this large public sector antiretroviral treatment program. This marker may have a role in guiding programmatic monitoring and clinical care in resource-constrained settings.

15. Peer Reviewed Title: CD4+ response and subsequent risk of death among patients on antiretroviral therapy in Lusaka, Zambia. Author: Chi BH; Giganti M; Mulenga PL; Limbada M; Reid SE; Mutale W; Stringer JS Source: Journal of Acquired Immune Deficiency Syndromes. 2009 Sep 1;52(1):125-31. Abstract: INTRODUCTION: Where virologic monitoring is not routinely available, immunologic criteria are commonly used to determine treatment failure while on antiretroviral therapy (ART). However, few have studied CD4+ response and its relationship to subsequent clinical outcomes in a programmatic setting. METHODS: We analyzed cohort data from Zambia to investigate whether 6- and 12-month CD4+ response after ART initiation was associated with later mortality. We used Cox proportional hazards models that accounted for different strata of baseline CD4 counts and adjusted for age, sex, clinical stage, tuberculosis coinfection, baseline hemoglobin, initial ART regimen, and adherence behavior. RESULTS: We analyzed data from 2 cohorts, from 6 months onward (n = 24,366; median follow-up = 467 days, interquartile range 222-791) and from 12 months onward (n = 17,920; median follow-up = 423 days, interquartile range 191-689). In the post-6-month analysis, hazard for death was significantly higher when absolute CD4+ response was <100 cells per microliter [adjusted hazard ratio (AHR) = 2.25, 95% confidence interval (CI): 1.91 to 2.64], relative response was <10% above baseline (AHR = 2.60, 95% CI: 2.12 to 3.19), and absolute CD4+ count was <100 per microliter (AHR = 2.79, 95% CI: 2.26 to 3.45). In the post-12 month analysis, mortality was associated with rise in absolute CD4+ cell count <200 per microliter (AHR = 2.41, 95% CI: 1.83 to 3.17), relative rise in CD4+ cell count of <10% above baseline (AHR = 3.41, 95% CI: 2.51 to 4.64), and absolute CD4+ count at 12 months <100 per microliter (AHR = 4.11, 95% CI: 2.96 to 5.68). CONCLUSION: Commonly used definitions for immunologic treatment failure are associated with elevated mortality risk among patients on ART.

Author: Collini P; Schwab U; Sarfo S; Obeng-Baah J; Norman B; Chadwick D; Bibby D; Bedu-Addo G Source: Clinical Infectious Diseases. 2009 Apr 1;48(7):988-91. Abstract: Two hundred thirty-seven Ghanaian human immunodeficiency virus-infected patients who were starting antiretroviral therapy underwent clinical and immunological monitoring for 3 years. Seventy-eight percent of patients had disease classified as World Health Organization stage III or IV. The mean increase in the CD4 cell count was 395 cells/mm(3), 13% of patients experienced immunological failure, and 8% of patients switched treatment to a second-line regimen. However, two-thirds of patients who experienced immunological failure did not switch treatment, and 31% of all patients were lost to follow-up.

17. Peer Reviewed Title: Measuring trends in age at first sex and age at marriage in Manicaland, Zimbabwe. Author: Cremin I; Mushati P; Hallett T; Mupambireyi Z; Nyamukapa C; Garnett GP; Gregson S Source: Sexually Transmitted Infections. 2009 Apr;85(Suppl 1):i34-i40. Abstract: The authors analyzed longitudinal data from three rounds of a population-based cohort in eastern Zimbabwe. Reports of age at first sex and age at marriage from 6,837 individuals attending multiple rounds were classified according to consistency. Survival analysis was used to identify trends in the timing of first sex and marriage. In this population, women initiate sex and enter marriage at younger ages than men but spend much less time between first sex and marriage. Among those surveyed between 1998 and 2005, median ages at first sex and first marriage were 18.5 years and 21.4 years for men and 18.2 years and 18.5 years, respectively, for women aged 15-54 years. High levels of reports of both age at first sex and age at marriage among those attending multiple surveys were found to be unreliable. Excluding reports identified as unreliable from these analyses did not alter the observed trends in either age at first sex or age at marriage. Tracing birth cohorts as they aged revealed reporting biases, particularly among the youngest cohorts. Comparisons by birth cohorts, which span a period of >40 years, indicate that median age at first sex has remained constant over time for women but has declined gradually for men. Although many reports of age at first sex and age at marriage were found to be unreliable, inclusion of such reports did not result in artificial generation or suppression of trends.

18. Title: Perinatal mortality and morbidity in a nationwide cohort of 529,688 low-risk planned home and hospital births. Author: de Jonge A; van der Goes BY; Ravelli AC; Amelink-Verburg MP; Mol BW; Nijhuis JG; Bennebroek Gravenhorst J; Buitendijk SE Source: BJOG. 2009 Aug;116(9):1177-84. Abstract: OBJECTIVE: To compare perinatal mortality and severe perinatal morbidity between planned home and planned hospital births, among low-risk women who started their labour in primary care. DESIGN: A nationwide cohort study. SETTING: The entire Netherlands. POPULATION: A total of 529,688 low-risk women who were in primary midwife-led care at the onset of labour. Of these, 321,307 (60.7%) intended to give birth at home, 163,261 (30.8%) planned to give birth in hospital and for 45,120 (8.5%), the intended place of birth was unknown. METHODS: Analysis of national perinatal and neonatal registration data, over a period of 7 years. Logistic regression analysis was used to control for differences in baseline characteristics. MAIN OUTCOME MEASURES: Intrapartum death, intrapartum and neonatal death within 24 hours after birth, intrapartum and neonatal death within 7 days and neonatal admission to an intensive care unit. RESULTS: No significant differences were found between planned home and planned hospital birth (adjusted relative risks and 95% confidence intervals: intrapartum death 0.97 (0.69 to 1.37), intrapartum death and neonatal death during the first 24 hours 1.02 (0.77 to 1.36), intrapartum death and neonatal death up to 7 days 1.00 (0.78 to 1.27), admission to neonatal intensive care unit 1.00 (0.86 to 1.16). CONCLUSIONS: This study shows that planning a home birth does not increase the risks of perinatal mortality and severe perinatal morbidity among low-risk women, provided the maternity care system facilitates this choice through the availability of well-trained midwives and through a good transportation and referral system.

19. Peer Reviewed Title: Intrauterine devices for adolescents: a systematic review. Author: Deans EI; Grimes DA Source: Contraception. 2009 Jun;79(6):418-23. Abstract: BACKGROUND: The appropriateness of IUDs for adolescents remains unsettled, as does the definition of the term adolescent. Unplanned pregnancy among teenagers remains epidemic, and long-acting methods, such as IUDs, offer the promise of top-tier effectiveness. STUDY DESIGN: We conducted a systematic review of the literature concerning IUD use in adolescents using MEDLINE, Popline, EMBASE and CINAHL databases. RESULTS: Six cohort studies and seven case-series reports met our inclusion criteria; none included IUDs in current use in the United States. Overall, continuation rates were high and cumulative pregnancy rates low, ranging from 2% at 6 months to 11% at 48 months. Compared with combined oral contraceptives, IUDs had similar or better continuation rates; pregnancy rates were similar at 2 years. IUD expulsion rates may be inversely related to age. CONCLUSIONS: The literature on IUD use among adolescents is scanty and obsolete. Nevertheless, published reports were generally reassuring. Randomized controlled trials and cohort studies comparing contemporary IUDs with other methods are urgently needed.

STUDY DESIGN: In a planned secondary analysis, we used data from the European Active Surveillance Study on Oral Contraceptives, which was a prospective active cohort surveillance study of 59,510 OC users, to assess the effectiveness of OCs overall and by BMI, weight, age, duration of use, ethinylestradiol dose, regimen type, starting/switching status, and parity. Self-reported unplanned pregnancies during OC use were confirmed by interview. RESULTS: An analysis of OC effectiveness (112,659 women-years of exposure and 545 unplanned pregnancies) found little variation in effectiveness by BMI/weight. Failure rates decreased after 30 years of age and with an increasing duration of use. CONCLUSION: OC users in Europe reported high contraceptive effectiveness with "typical use." Failure rates decreased with age and duration ofuse. BMI and weight had little, if any, influence on effectiveness.

21. Title: HIV stigma and missed medications in HIV-positive people in five African countries. Author: Dlamini PS; Wantland D; Makoae LN; Chirwa M; Kohi TW; Greeff M; Naidoo J; Mullan J; Uys LR; Holzemer WL Source: AIDS Patient Care and STDs. 2009 May;23(5):377-87. Abstract: The availability of antiretroviral medications has transformed living with HIV infection into a manageable chronic illness, and high levels of adherence are necessary. Stigma has been identified as one reason for missing medication doses. The objective of this study was to explore the relationship between perceived HIV stigma and self-reported missed doses of antiretroviral medications in a 12-month, repeated measures cohort study conducted in Lesotho, Malawi, South Africa, Swaziland, and Tanzania. Data were collected from 1457 HIV-positive individuals at three times between January 2006 and March 2007. Participants completed a series of questionnaires. Of the 1457 participants, 698 were taking ARVs during the study and are included in this analysis. There was a significant relationship between perceived HIV stigma and self-report of missed medications over time (t = 6.04, p = 0.001). Individuals who reported missing more ARV medications also reported higher levels of perceived HIV stigma. Individuals reporting fewer medication worries reported decreased stigma over the one year period (t = -4.79, p = 0.001). While those who reported increased symptom intensity also reported increased stigma initially (t = 8.67, p = 0.001) that remained high over time. This study provides evidence of a significant and stable correlation that documents the relationship between perceived HIV stigma and self-reported reasons for missed medications over time. These findings suggest that part of the reason for poor adherence to ARV medications is linked to the stigma experienced by people living with HIV.

22. Peer Reviewed Title: Anthropometric indices of infants born to HIV-1-infected mothers: a prospective cohort study in Lagos, Nigeria. Author: Ezeaka VC; Iroha EO; Akinsulie AO; Temiye EO; Adetifa IM Source: International Journal of STD and AIDS. 2009 Aug;20(8):545-8. Abstract: Numerous studies have reported that HIV-infected pregnant women are at increased risk of delivery of low birth weight (LBW) infants, of preterm deliveries and of intrauterine growth restriction. The objective of the study was to determine the effect of maternal HIV infection on the anthropometric characteristics of the babies at birth. A prospective study was carried out at the Lagos University Teaching Hospital, Nigeria. There were three times more LBW babies in the HIV-positive group than in the uninfected mothers (odds ratio = 3.47, 95% confidence interval = 1.69, 7.27; chi(2) = 12.99, P = 0.0003).The maternal weight (t = 15.85; P = 0.0001), maternal body mass index (BMI) (t = 15.07; P = 0.0003), birth weight of infants (t = 27.17; P = 0.0001) and birth length (t = 31.20; P = 0.001) were significantly less in HIV-positive mothers than in controls. In conclusion, poor maternal bodyweight and low BMI are significant contributors to LBW in HIV-infected women. Nutritional counselling, dietary intake and weight monitoring during pregnancy should be emphasized to improve pregnancy outcome in HIV-infected women.

23. Title: Longitudinal growth of infants born to HIV-1-infected mothers in Belo Horizonte, Brazil. Author: Fausto MA; Carneiro M; Antunes CM; Colosimo EA; Pinto JA Source: Public Health Nutrition. 2009 Jun;12(6):783-8. Abstract: OBJECTIVE: To prospectively evaluate growth parameters assessed by weight and length in infected and uninfected infants born to HIV-1-infected mothers and followed from birth to 18 months. METHODS: A cohort consisting of ninety-seven uninfected and forty-two infected infants born to HIV-infected mothers enrolled from 1995 to 2004, and admitted during their first 3 months of life at a referral Pediatric AIDS Clinic in Belo Horizonte, Brazil. Infants were followed until 18 months of age. Data were analysed using mixed-effects linear regression models for weight and length fitted by restricted maximum likelihood. RESULTS: Infected infants contributed to 466 weight and 411 recumbent length measurements. Uninfected infants provided 924 weight and 907 length measurements. Mean birth weight and length were similar in both groups, 3.1 (sd 0.4) and 3.0 (sd 0.5) kg, and 48.7 (sd 1.4) and 48.8 (sd 2.9) cm for uninfected and infected infants, respectively. However, HIV-1 infection had an early impact in growth impairment: at 6 months of age, HIV-infected children were 1 kg lighter and 2 cm shorter than the uninfected. CONCLUSIONS: Growth faltering in weight, but not length, in HIV-infected children in Brazil is more marked than that reported in a European cohort, probably reflecting background nutritional deficiencies and concomitant infections. In these settings, early and aggressive nutritional management in HIV-1-infected infants should be a priority intervention associated with the antiretroviral therapy.

24. Title: Birth weight of offspring, maternal pre-pregnancy characteristics, and mortality of mothers: the Jerusalem perinatal study cohort. Author: Friedlander Y; Manor O; Paltiel O; Meiner V; Sharon N; Calderon R; Hochner H; Sagy Y; Avgil M; Harlap S; Siscovick DS Source: Annals of Epidemiology. 2009 Feb;19(2):112-7. Abstract: PURPOSE: To explore the association between birth weight in offspring, a marker of the intrauterine environment, and mortality in their mothers, taking into account maternal pre-pregnancy characteristics, including maternal body mass index (BMI), smoking, and socioeconomic status. Distinguishing the effects of offspring's birth weight and pre-pregnancy characteristics on maternal outcome may provide clues regarding mechanisms underlying the association between birth weight and maternal mortality. METHODS: We studied long-term total mortality (average follow-up period, 29.1 years) in a population-based cohort of 13,185 mothers, aged 15 to 48 years at their offspring's birth, who delivered in West Jerusalem during 1974 through 1976. RESULTS: Univariate and multivariate Cox-proportional hazard models used to estimate the hazard of overall mortality among mothers indicated a nonlinear relationship with birth weight of offspring when introduced into the models as a continuous variable, and a linear positive association with maternal pre-pregnancy BMI. Inclusion of maternal BMI and other pre-pregnancy characteristics in the model did not alter the association between offspring's birth weight and mothers' all-cause mortality. When birth weight was introduced as a categorical variable, higher mortality was observed among mothers who gave birth to babies with birth weight less than 2500 g (hazard ratio [HR] = 1.90; 95% confidence interval [95%CI], 1.23-2.94) as compared to mothers whose offspring had birth weight between 3000 and 3499 g. The HR for mothers who gave birth to babies with birth weight 4000 g or more was 1.30 (95%CI, 0.88-1.91). CONCLUSIONS: Independent of pre-pregnancy maternal BMI and other characteristics, birth weight of offspring was associated with mortality in their mothers, suggesting that intrauterine metabolic events reflected by birth weight and not explained by maternal obesity, smoking, and socioeconomic status have remote consequences for maternal health. These findings underline the need to explore specific genetic and/or environmental mechanisms that account for these associations.

Abstract: BACKGROUND: Persistent infections with oncogenic human papillomavirus (HPV) types are causally related to cervical cancer. Little is known about the distribution of HPV types, independent risk factors of incidence and persistence, and patterns of persistence in sub-Saharan Africa. METHODS: A cohort of 2040 Zimbabwean women was enrolled in a randomized trial assessing the effect of diaphragm/gel provision on human immunodeficiency virus and HPV acquisition. Data from the study arms were pooled for this analysis because diaphragm/gel provision did not affect HPV acquisition and clearance. Clinicians collected cervical samples for HPV testing at enrollment, 12 months, and exit (median 21 months). RESULTS: HPV prevalence was 24.5% for any HPV type and 16.1% for oncogenic types. HPV incidence at 12 months was 23.3% for any HPV type and 11.4% for oncogenic types. HPV58 had the highest baseline prevalence (5.0%) and incidence (2.4%). Type-specific persistence was 29.8% among all HPV infections over a median of 21 months of follow-up. Baseline predictors of incident HPV infection were younger age, having more than 1 lifetime sexual partner, infrequent condom use, herpes simplex virus-2 positive serology, and having a sexually transmissible infection or a different HPV type at enrollment. Baseline predictors of persistent HPV infection were younger age, having more than 1 lifetime sexual partner, and having a high-risk partner. CONCLUSIONS: The novel association between herpes simplex virus-2 seropositivity and incident HPV infection warrants further investigation. Having a high-risk partner is a potentially modifiable risk factor for persistent HPV infection. The relatively high prevalence of HPV58 has implications for vaccine development.

26. Title: Knowledge, Use, and Concerns about Contraceptive Methods among Sero-Discordant Couples in Rwanda and Zambia. Author: Grabbe K; Stephenson R; Vwalika B; Ahmed Y; Vwalika C; Chomba E; Karita E; Kayitenkore K; Tichacek A; Allen S Source: Journal of Women's Health. 2009 Aug 26; Abstract: Abstract Objective: The unique needs of sero-discordant couples are largely missing from many current family planning efforts, which focus on the prevention of pregnancies in absence of the reduction of the risk of human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs). Conversely, HIV testing and programs focus exclusively on condom use without discussion of more effective contraceptive methods. In order to provide information to inform the development of family planning services tailored to the unique needs of sero-discordant couples, this study examined the contraceptive knowledge, use, and concerns among sero-discordant couples in urban Rwanda and Zambia. Methods: This article presents a comparison of family planning knowledge, use, and concerns about contraception among two cohorts of HIV sero-discordant study participants in Rwanda and Zambia. Results: The results reveal an interesting profile of contraceptive knowledge and use among sero-discordant couples; in both settings, despite high levels of knowledge of contraception, use of contraceptive methods remains relatively low. There is a clear gender difference in both the reporting of knowledge and use of contraceptive methods, and there is evidence of clandestine contraceptive use by women. Conclusions: Including information on family planning in voluntary counseling and testing (VCT) services in addition to tailoring the delivery of family planning information to meet to needs and concerns of HIV-positive women or those with HIV positive partners is an essential step in the delivery of services and prevention efforts to reduce the transmission of HIV. Family planning and HIV prevention programs should integrate counseling on "dual method use," combining condoms for HIV/STI prevention with a long-acting contraceptive for added protection against unplanned pregnancy.

28. Peer Reviewed Title: Relatively low HIV infection rates in rural Uganda, but with high potential for a rise: a cohort study in Kayunga District, Uganda.

Abstract: BACKGROUND: Few studies have been conducted in Uganda to identify and quantify the determinants of HIV-1 infection. We report results from a community-based cohort study, whose primary objectives were to determine HIV-1 prevalence, incidence, and determinants of these infections, among other objectives. METHODOLOGY: Consenting volunteers from the rural district of Kayunga in Uganda aged 15-49 years were enrolled between March and July 2006. Participants were evaluated every six months. A questionnaire that collected information on behavioral and other HIV-1 risk factors was administered, and a blood sample obtained for laboratory analysis at each study visit. PRINCIPAL FINDINGS: HIV-1 prevalence among the 2025 participants was 9.9% (95% CI = 8.6%-11.2%). By the end of 12 months of follow-up, 1689.7 person-years had been accumulated, with a median follow-up time of 11.97 months. Thirteen HIV-1 incident cases were detected giving an annual HIV-1 incidence of 0.77% (95% CI = 0.35-1.19). Prevalence of HSV-2 infection was 57% and was strongly associated with prevalent HIV-1 infection (adjusted Odds Ratio = 3.9, 95% CI = 2.50-6.17); as well as incident HIV-1 infection (adjusted Rate Ratio (RR) = 8.7, 95% CI = 1.11-67.2). The single most important behavioral characteristic associated with incident HIV infection was the number of times in the past 6 months, a participant had sex with person(s) they suspected/knew were having sex with others; attaining statistical significance at 10 times and higher (adjusted RR = 6.3, 95% CI = 1.73-23.1). By the end of 12 months of follow-up, 259 participants (13%) were lost to follow-up, 13 (0.6%) had died, and 2 (0.1%) had withdrawn consent. CONCLUSIONS: Despite relatively low HIV-1 incidence observed in this community, prevalence remains relatively high. In the presence of high prevalence of HSV-2 infection and the behavioral characteristic of having sex with more than one partner, there is potential for increase in HIV-1 incidence.

29. Title: Monitoring HIV epidemics: declines in prevalence do not always mean good news [editorial] Author: Hallett T Source: AIDS. 2009 Jan 2;23(1):131-2. Abstract: The future of HIV epidemic monitoring is likely to rely on HIV prevalence for many years to come. After years of intensive research, direct measurements of incidence in local cohort studies are becoming less and less representative of whole countries, and assays that discriminate recent infections in cross-sectional serosurveys have been shown to be unreliable in African countries without calibration. Antiretroviral therapy will add a further layer of complexity, as longer survival times will tend to increase HIV prevalence; so that upturns in epidemics may not indicate increased risk behaviour, and stable prevalence rates could mask substantial reductions in incidence. It will, therefore, be essential to make maximum use of mathematical modelling in the interpretation of trends in HIV prevalence. To be conservative and defensible, these modelsmust reasonably account for all other potential sources of natural changes in epidemics, so that the contribution of actual reductions in risk-if any-can be resolved. And only from that starting point, can the important investigations into the proximal and distal causes and reasons for the behaviour changes begin.

| 30. Title: Paediatric antiretroviral therapy outcomes under HIV hospice care in South Africa. Author: Harding R; Brits H; Penfold S Source: International Journal of Palliative Nursing. 2009 Mar;15(3):142-5. Abstract: AIM: This study aims to evaluate outcomes of children with advanced HIV disease who are initiated on antiretroviral therapy under multiprofessional specialist paediatric hospice care. DESIGN: A retrospective cohort file review methodology was undertaken in a specialist paediatric hospice in South Africa. METHODS: Antiretroviral therapy was initiated for children with a CD4% of less than 15% (for children under 6 years of age) or a CD4 count under 200 for children over 6 years of age. According to the World Health Organization Europe (2007) staging criteria, all children were stage 3/4 HIV disease. Multiprofessional staff provided daily tailored assessment and care. Each child was followed for 6 months. Data on mortality, CD4 count, CD4 percentage, body weight, and viral load were measured at initiation and a follow-up after 6 months. FINDINGS: Of the 37 children initiated on ART therapy, 31 I survived at 6 months. From a baseline of mean body weight 13.3 kg, there was an average of 3.2 kg increase (P < 0.001). Mean CD4 counts more than doubled (P < 0.001), with a mean increase of 467 cells per mm3 blood. Mean CD4 percentages increased from 13.6-19.4% (P < 0.001).Viral load decreased significantly from a median 271000 copies per mm3 blood to a median of 25 (imputed value for undetectable viral load) (P < 0.001). Twenty-three children had an undetectable viral load. CONCLUSION: For children with advanced HIV disease, who are least likely to access or respond to treatment, this study demonstrates a novel approach to managing care successfully.
