More about Aggrey and Akori beads
No full textThis contribution is a further continuation of a discussion, begun by Professor Mauny and continued by the present author, into the nature and provenance of the aggrey or akori beads formerly imported into the Gold Coast (i.e. the south of modern Ghana). It considers at length the evidence provided by E.J.P. Brown, a notable Fante personality of the early twentieth century, in his book, The Gold Coast and Asianti Reader (1929), and compares this with some actual bead samples and with linguistic and literary evidence not used in the earlier discussion. This evidence leads to the tentative conclusions that : 1) The original and most prized blue aggrey/akori bead was made of glass ; 2) It was identical with the Yoruba segi bead ; 3) Its import into the Gold Coast may have ceased in the mid nineteenth century ; 4) That its principal place of manufacture may have been Ife, where glass working may also have ceased in the mid nineteenth century.Cette contribution reprend un débat entamé par R. Mauny et poursuivi par l’auteur sur la nature et la provenance des perles aggrey ou akori importées autrefois en Gold Coast (sud du Ghana actuel). On analyse méthodiquement les arguments fournis par E J. P. Brown, un notable Fanti du debut du XXe siècle, dans son livre, The Gold Coast and Asianti Reader (1929) et on les confronte avec des échantillons actuels de perles et avec des preuves linguistiques et littéraires non utilisées dans les discussions antérieures. Cette argumentation permet de proposer les premières conclusions suivantes : 1) L’ancienne perle bleue aggrey/akori, qui était la plus appréciée, était faite en verre ; 2) elle était identique à la perle yoruba segi ; 3) son importation en Gold Coast semble avoir cessé à partir du milieu du XIXe siècle ; 4) son principal lieu de fabrication peut avoir été Ifé où la manufacture du verre peut aussi avoir cessé au milieu du XIXe siècle.Fage John Donnelly.

Survival and predictors of mortality after completion of TB treatment among people living with HIV: a 5-year analytical cohort
No full textAbstract Background After completion of TB treatment patients may remain at risk of co-morbidity and mortality. We determined the survival and predictors of all-cause mortality after completing TB treatment among ART-experienced patients. Methods This was a retrospective cohort analysis of all ART experienced patients who completed TB treatment at a specialist HIV clinic in Uganda, between 2009 and 2014. The patients were followed for five years after TB treatment. We determined the cumulative probability of death, and predictors of mortality using Kaplan-Meier methods and Cox proportional hazard models, respectively. Results A total 1,287 patients completed TB treatment between 2009 and 2014, of which 1,111 were included in the analysis. At TB treatment completion, the median age was 36 years (IQR: 31–42), 563 (50.7%) were males, and median CD4 cell count was 235 cells/mL (IQR: 139–366). The person-time at risk was 4410.60 person-years. The all-cause mortality rate was 15.42 (95% CI: 12.14–19.59) per 1000 person-years. The probability of death at five years was 6.9% (95%CI: 5.5- 8.8). In the multivariable analysis, CD4 count < 200 cells/mL was a predictor of all-cause mortality (aHR = 1.81, 95%CI:1.06–3.11, p = 0.03) alongside history of retreatment (aHR = 2.12, 95%CI: 1.16–3.85, p = 0.01). Conclusion Survival post TB treatment in ART experienced PLHIV is reasonably good. Most deaths occur within two years after TB treatment completion. Patients with a low CD4 count and those with a history of retreatment have an increased risk of mortality which underscores the need for TB prophylaxis, detailed assessment, and close monitoring after completion of TB treatment

Hypertension and associated risk factors in individuals infected with HIV on antiretroviral therapy at an urban HIV clinic in Uganda
No full textAbstractBackgroundScale-up of antiretroviral therapy (ART) might precipitate an increase in non-communicable diseases (NCDs) in adults infected with HIV in sub-Saharan Africa based on data from resource-rich settings. Hypertension is a major modifiable risk factor for cerebrovascular and cardiovascular NCDs. We estimated prevalence, incidence, and risk factors for incident hypertension in adults infected with HIV on ART at an urban clinic in Uganda.MethodsFrom a cohort of adults infected with HIV (>18 years) who initiated ART between Jan 1, 2005, and Jan 3, 2012, at the Infectious Diseases Institute clinic in Kampala, we report the prevalence, incidence, and cumulative incidence (with death as a competing risk) of hypertension (≥140/90 mm Hg). Risk factors for hypertension were evaluated with Cox proportional hazards regression.FindingsOf 9806 individuals who initiated ART, 6351 (64·8%) were women, median age was 36 years (IQR 31–42), and median follow-up was 3·9 years (2·2–5·9). Overall prevalence of hypertension was 15·1% (1472 individuals); older individuals (>50 years) had higher prevalence (299, 38·6%). By year 1, cumulative incidence was 1% and by year 5, it was 3·6%. Overall incidence was 19 cases per 1000 person-years. Multivariate regression showed male sex, older age, increasing body-mass index, and use of stavudine at initiation was associated with an increased rate of hypertension.InterpretationOf our patients, we noted a prevalence of hypertension between 14·6% and 28·5%, similar to the general Ugandan population. Besides traditional risk factors for hypertension, use of stavudine was also identified. Awareness of NCD comorbidity and AIDS-associated risk factors are increasingly important for clinicians caring for adults on ART in sub-Saharan Africa.FundingUniversity of California Global Health Institute (UCGHI) supported GloCal Fellowship funded by the Fogarty International Center (FIC) at the National Institutes of Health (NIH) R25TW009343
Impact of antiretroviral therapy on the incidence of Kaposi's sarcoma in resource-rich and resource-limited settings
No full textImpact of antiretroviral therapy on the incidence of Kaposi's sarcoma in resource-rich and resource-limited settings
No full textPURPOSE OF REVIEW: Given the recent availability of antiretroviral therapy (ART) in resource-limited settings and the significant burden exacted by Kaposi's sarcoma in these areas, we reviewed data regarding the impact of ART on Kaposi's sarcoma incidence. We summarized the sizeable literature in resource-rich settings as well as emerging data from resource-limited regions. Importantly, we delineated ways impact can be defined, including individual patient-level effectiveness; population-level effectiveness; change in population-level incidence; and residual risk of Kaposi's sarcoma.
RECENT FINDINGS: In resource-rich settings, there are now ample data demonstrating beneficial individual patient-level and population-level effects of ART on Kaposi's sarcoma incidence. There is, however, considerable variability between studies and important methodologic shortcomings. Data from resource-limited settings are much more limited; although they preliminarily indicate individual patient-level effectiveness, they do not yet provide insight on population-level effects.
SUMMARY: ART has had a substantial impact on Kaposi's sarcoma incidence in resource-rich settings, but more attention is needed on validly quantifying this effect in order to determine whether additional interventions are needed. Emerging data from resource-limited regions also suggest beneficial impact of ART on Kaposi's sarcoma incidence, but - given the scope of Kaposi's sarcoma in these settings - more data are needed to understand the breadth and magnitude of the effect
A genetic variation map for chicken with 2.8 million single-nucleotide polymorphisms
No full textWe describe a genetic variation map for the chicken genome containing 2.8 million single-nucleotide polymorphisms (SNPs). This map is based on a comparison of the sequences of three domestic chicken breeds (a broiler, a layer and a Chinese silkie) with that of their wild ancestor, red jungle fowl. Subsequent experiments indicate that at least 90% of the variant sites are true SNPs, and at least 70% are common SNPs that segregate in many domestic breeds. Mean nucleotide diversity is about five SNPs per kilobase for almost every possible comparison between red jungle fowl and domestic lines, between two different domestic lines, and within domestic lines--in contrast to the notion that domestic animals are highly inbred relative to their wild ancestors. In fact, most of the SNPs originated before domestication, and there is little evidence of selective sweeps for adaptive alleles on length scales greater than 100 kilobases
