To systematically review the current literature on treatment of third and fourth branchial pouch sinuses with endoscopic cauterization, including chemocauterization and electrocauterization, in comparison to surgical treatment.

PubMed, Embase, and the Cochrane Library.

We conducted a systematic search. Studies reporting original study data were included. After assessing the directness of evidence and risk of bias, studies with a low directness of evidence or a high risk of bias were excluded from analysis. Cumulative success rates after initial and recurrent treatments were calculated for both methods. A meta-analysis was conducted comparing the success rate of electrocauterization and surgery.

A total of 2,263 articles were retrieved, of which seven retrospective and one prospective article were eligible for analysis. The cumulative success rate after primary treatment with cauterization ranged from 66.7% to 100%, and ranged from 77.8% to 100% after a second cauterization. The cumulative success rate after the first surgical treatment ranged from 50% to 100% and was 100% after the second surgical attempt. Meta-analysis on electrocauterization showed a nonsignificant risk ratio of 1.35 (95% confidence interval 0.78-2.33).

The effectiveness of cauterization in preventing recurrence seems to be comparable to surgical treatment. However, we suggest endoscopic cauterization as the treatment of choice for third and fourth branchial pouch sinuses because of the lower morbidity rate.

These tips, which apply to all fields of academic writing, advise that during the initial preparation phase authors should (1) plan early to get it out the door; (2) address authorship and writing group expectations up front; (3) maintain control of the writing; (4) ensure complete reporting; (5) use electronic reference management software; (6) polish carefully before they submit; (7) select the right journal; and (8) follow journal instructions precisely. Rejection after the first submission is likely, and when this occurs authors should (9) get it back out the door quickly, but first (10) take seriously all reviewer and editor suggestions. Finally, when the invitation comes to revise and resubmit, authors should (11) respond carefully to every reviewer suggestion, even if they disagree, and (12) get input from others as they revise. The author also shares detailed suggestions on the creation of effective tables and figures, and on how to respond to reviewer critiques.We report the case of a 56-year-old Caucasian woman in whom hemoglobinopathy screening was triggered following an aberrant Hb A1c analysis. Preliminary diagnosis of the hemoglobin (Hb) variant was obtained through cation exchange high performance liquid chromatography (HPLC) and gel electrophoresis. DNA analysis confirmed the presence of Hb J-Amiens [β17(A14)Lys→Asn; HBB c.[54G > C or 54G > T)]. However, an unbalanced ratio between wild type and mutant signal after direct sequencing and a lower than expected percentage of this Hb variant led to the suggestion of a mosaic expression. Furthermore, different methods [capillary zone electrophoresis (CZE), cation exchange HPLC and boronate affinity] were tested to study the possible interference of this variant with Hb A1c measurements. These investigations showed a clinically relevant difference between the methods tested. Hb A1c analysis may lead to the discovery of new Hb variants or mosaicism for previously described Hb variants. This may have genetic consequences for the offspring of carriers and brings about the question of partner testing.The interferon (IFN)L4 polymorphism rs368234815 is associated with hepatitis C virus (HCV) spontaneous clearance and response to IFN-based treatments. The role of this polymorphism in HIV-1 infection is controversial. We investigated whether genetic variation at IFNL4 is associated to HIV-1 acquisition. The HCV protective allele TT was associated with decreased likelihood of HIV-1 infection in male intravenous drug users [odds ratio (OR) 0.3; P = 0.006], and this association was not modified by the genotype of CCR5. These results suggest that genetic susceptibility to HCV and HIV-1 infection shares common molecular pathways.
The current Ebola epidemic massively affected the Macenta district in Forest Guinea. We aimed at investigating its impact on general and HIV care at the only HIV care facility in the district.

Prospective observational single-facility study.

Routinely collected data on use of general hospital services and HIV care were linked to Ebola surveillance data published by the Guinea Ministry of Health. In addition, we compared retention among HIV-infected patients enrolled into care in the first semesters of 2013 and 2014.

Throughout 2014, service offer was continuous and unaltered at the facility. During the main epidemic period (August-December 2014), compared with the same period of 2013, there were important reductions in attendance at the primary care outpatient clinic (-40%), in HIV tests done (-46%), in new diagnoses of tuberculosis (-53%) and in patients enrolled into HIV care (-47%). There was a smaller reduction in attendance at the HIV follow-up clinic (-11%). Kaplan-Meier estimates of retention were similar among the patients enrolled into care in 2014 and 2013. In a multivariable Cox regression analysis, the year of enrolment was not associated with attrition (hazard ratio 1.02; 95% confidence interval 0.72-1.43).

The Ebola epidemic resulted in an important decrease in utilization of the facility despite unaltered service offer. Effects on care of HIV-positive patients enrolled prior to the epidemic were limited. HIV care in such circumstances is challenging, but not impossible.

To obtain a comprehensive description of the evolutionary and demographic history of major HIV-1 subtype B pandemic (BPANDEMIC) clades circulating in Latin America.

A total of 6789 HIV-1 subtype B pol sequences collected from seven different Latin American countries between 1990 and 2011 were combined with BPANDEMIC reference sequences (n = 500) from the United States and France.

Major BPANDEMIC clades were identified by maximum likelihood phylogenetic analysis with sequential pruning of ambiguously positioned taxa. Time scale and demographic reconstructions were performed using a Bayesian coalescent-based method.

We identified 12 major BPANDEMIC monophyletic lineages mainly composed by Latin American sequences and that together comprise 36% of all subtype B sequences from the region here included. Four clades belong to two major regional lineages that comprise sequences from at least two neighboring countries, whereas the other eight clades were country-specific. The median age of major Latin American BPANDEMIC clades encompass a period of two decades (1968-1988), although most of them probably arose before the early 1980s. All major clades seem to have experienced an initial period of exponential growth, with median epidemic growth rates that range from 0.50 yearto 0.94 year, followed by a recent decline in growth rate.

About one-third of HIV-1 subtype B infections in Latin America originated from the spread of a few BPANDEMIC founder strains probably introduced in the region since the late 1960s. Despite their initial successful dissemination, all major BPANDEMIC clades showed signs of subsequent epidemic stabilization.

Increased rates of testing, with early antiretroviral therapy (ART) initiation, represent a key potential HIV-prevention approach. Currently, in MSM in the United Kingdom, it is estimated that 36% are diagnosed by 1 year from infection, and the ART initiation threshold is at CD4 cell count 350/μl. We investigated what would be required to reduce HIV incidence in MSM to below 1 per 1000 person-years (i.e. <535 new infections per year) by 2030, and whether this is likely to be cost-effective.

A dynamic, individual-based simulation model was calibrated to multiple data sources on HIV in MSM in the United Kingdom. Outcomes were projected according to future alternative HIV testing and ART initiation scenarios to 2030, considering also potential changes in levels of condomless sex.

For ART use to result in an incidence of close to 1/1000 person-years requires the proportion of all HIV-positive MSM with viral suppression to increase from below 60% currently to 90%, assuming no rise in levels of condomless sex. Substantial increases in HIV testing, such that over 90% of men are diagnosed within a year of infection, would increase the proportion of HIV-positive men with viral suppression to 80%, and it would be 90%, if ART is initiated at diagnosis. The scenarios required for such a policy to be cost-effective are presented.

This analysis provides targets for the proportion of all HIV-positive MSM with viral suppression required to achieve substantial reductions in HIV incidence.

National estimates of HIV trends in generalized epidemics rely on HIV prevalence data from antenatal clinic (ANC) surveillance. We investigate whether HIV prevalence trends in ANC data reflect trends in men and women in the general population during the scale-up of antiretroviral therapy (ART) in Manicaland, Zimbabwe.

Trends in HIV prevalence in local ANC attendees and adults aged 15-49 years in towns, agricultural estates, and villages were compared using five rounds of parallel ANC (N = 1200) and general-population surveys (N = 10 000) and multivariable log-linear regression. Changes in the age pattern of HIV prevalence and the age distribution of ANC attendees were compared with those in the general population. GX15-070 Age-specific pregnancy prevalence rates were compared by HIV infection and ART status.

Cumulatively, from 1998-2000 to 2009-2011, HIV prevalence fell by 60.0% (95% confidence interval, 51.1-67.3%) in ANC surveillance data and by 34.3% (30.8-37.7%) in the general population. Most of the difference arose following the introduction of ART (2006-2011). The estates and villages reflected this overall pattern but HIV prevalence in the towns was lower at local ANCs than in the general population, largely because of attendance by pregnant women from outlying (lower prevalence) areas. The ageing of people living with HIV in the general population (52.4% aged >35 years, 2009-2011) was under-represented in the ANC data (12.6%) because of lower fertility in older and HIV-infected women.

After the introduction of ART in Manicaland, HIV prevalence declined more steeply in ANC surveillance data than in the general population. Models used for HIV estimates must reflect this change in bias.
