Adherence to oral HIV pre-exposure prophylaxis among female sex workers in Kampala, Uganda
Introduction: In Kampala Uganda, female sex workers (FSWs) have high
HIV prevalence (33%). Oral PrEP is a novel HIV prevention intervention
that offers hope to decrease HIV incidence in key populations
especially among FSWs. Studies have shown that with poor adherence,
oral PrEP has no efficacy, and therefore adherence to PrEP is critical
among FSWs to maximize HIV prevention. However, implementation data on
adherence to PrEP among FSWs is limited so this study sought to assess
adherence to PrEP. Specifically, we sought to 1) determine the level of
adherence to PrEP among FSWs, and 2) determine factors associated with
PrEP adherence. Methods: This cross-sectional study was conducted from
November to December 2018; 126 FSWs using PrEP were interviewed using a
questionnaire. Adherence was categorically defined as high adherence
and low adherence. Logistic regression was done. Results: Using
long-term contraception methods (OR 0.06, 95% CI: 0.04-0.77) and not
using condoms with clients (OR 0.07, 95% CI: 0.01-0.42) were negatively
associated with high PrEP adherence. Conclusion: Barriers to PrEP
adherence need to be addressed for successful PrEP implementation to
improve adherence going forward. Service care providers should
reinforce positive behaviors such as use of condoms devotedly during
PrEP breaks
Quality of data collection in a large HIV observational clinic database in sub-Saharan Africa: implications for clinical research and audit of care
<p>Abstract</p> <p>Background</p> <p>Observational HIV clinic databases are now widely used to answer key questions related to HIV care and treatment, but there has been no systematic evaluation of their quality of data. Our objective was to evaluate the completeness and accuracy of recording of key data HIV items in a large routine observational HIV clinic database.</p> <p>Methods</p> <p>We looked at the number and rate of opportunistic infections (OIs) per 100 person years at risk in the 24 months following antiretroviral therapy (ART) initiation in 559 patients who initiated ART in 2004-2005 and enrolled into a research cohort. We compared this with data in a routine clinic database for the same 559 patients, and a further 1233 patients who initiated ART in the same period. The Research Cohort database was considered as the reference "gold standard" for the assessment of data accuracy. A crude percentage of underreporting of OIs in the clinic database was calculated based on the difference between the OI rates reported in both databases.</p> <p>We reviewed 100 clinic patient medical records to assess the accuracy of recording of key data items of OIs, ART toxicities and ART regimen changes.</p> <p>Results</p> <p>The overall incidence rate per 100 person years at risk for the initial OI in the 559 patients in the research cohort and clinic databases was 24.1 (95% CI: 20.5-28.2) and 13.2 (95% CI: 10.8-16.2) respectively, and 10.4 (95% CI: 9.1-11.9) for the 1233 clinic patients. This represents a 1.8- and 2.3-fold higher rate of events in the research cohort database compared with the same 599 patients and 1233 patients in the routine clinic database, or a 45.1% and 56.8% rate of underreporting, respectively. The combined error rate of missing and incorrect items from the medical records' review was 67% for OIs, 52% for ART-related toxicities, and 83% and 58% for ART discontinuation and modification, respectively.</p> <p>Conclusions</p> <p>There is a high rate of underreporting of OIs in a routine HIV clinic database. This has important implications for the use and interpretation of routine observational databases for research and audit, and highlights the need for regular data validation of these databases.</p
European Code against Cancer 4th Edition: Alcohol drinking and cancer.
Alcohol consumption is the third leading risk factor for disease and mortality in Europe. As evaluated by the International Agency for Research on Cancer (IARC) Monographs, a causal relationship is established for consumption of alcoholic beverages and cancers of the oral cavity, pharynx, larynx, oesophagus, liver, colorectum and female breast, even at low and moderate alcohol intakes. The higher the amount of alcohol consumed, the higher the risk of developing cancer. In Europe, an estimated 10% (95% CI: 7%-13%) of all cancer cases in men and 3% (95% CI: 1%-5%) of all cancer cases in women are attributable to alcohol consumption. Several biological mechanisms explain the carcinogenicity of alcohol; among them, ethanol and its genotoxic metabolite, acetaldehyde, play a major role. Taking all this evidence into account, a recommendation of the 4th edition of European Code against Cancer is: "If you drink alcohol of any type, limit your intake. Not drinking alcohol is better for cancer prevention.
Rapid identification of bovine MHCI haplotypes in genetically divergent cattle populations Using Next-Generation Sequencing
The major histocompatibility complex (MHC) region contains many genes that are key regulators of both innate and adaptive immunity including the polymorphic MHCI and MHCII genes. Consequently, the characterisation of the repertoire of MHC genes is critical to understanding the variation that determines the nature of immune responses. Our current knowledge of the bovine MHCI repertoire is limited with only the Holstein-Friesian breed having been studied in any depth. Traditional methods of MHCI genotyping are of low resolution and laborious and this has been a major impediment to a more comprehensive analysis of the MHCI repertoire of other cattle breeds. Next-generation sequencing (NGS) technologies have been used to enable high throughput and much higher resolution MHCI typing in a number of species. In this study we have developed a MiSeq platform approach and requisite bioinformatics pipeline to facilitate typing of bovine MHCI repertoires. The method was validated initially on a cohort of Holstein-Friesian animals and then demonstrated to enable characterisation of MHCI repertoires in African cattle breeds, for which there was limited or no available data. During the course of these studies we identified >140 novel classical MHCI genes and defined 62 novel MHCI haplotypes, dramatically expanding the known bovine MHCI repertoire
Nutritional Supplement Practices of Professional Ugandan Athletes: A Cross-Sectional Study
BackgroundThe use of nutritional supplements (NS) places athletes at great risk for inadvertent doping. Due to the paucity of data on supplement use, this study aimed to determine the proportion of Ugandan athletes using nutritional supplements and to investigate the athletesâ motivation to use these supplements.MethodsA cross-sectional study was conducted in which an interviewer-administered questionnaire was used to collect data from 359 professional athletes participating in individual (boxing, cycling, athletics) and team (basketball, rugby, football, netball, and volleyball) sports. The data were categorized, and a Chi-square test was used for statistical analysis.ResultsOf the 359 athletes, 48 (13.4%) used nutritional supplements. Carbohydrate supplements, energy drinks, vitamin and mineral supplements, fish oils, and protein supplements were the most common supplements used by athletes. NS use was significantly more common among athletes who played rugby and basketball (X 2 = 61.101, p \u3c 0.0001), athletes who had played the sport for 5-10 years (X 2 = 7.460, p = 0.024), and athletes who had attained a tertiary education (X 2 = 33.377, p \u3c 0.0001). The athletesâ occupation had no bearing on whether they used supplements. Nutritionists/dieticians, retail stores and pharmacies were the most common sources of NS products, whereas health practitioners, online media and teammates were the most common sources of information regarding NS. Most athletes used NS to improve their physical performance and health.ConclusionsCompared to NS use by athletes elsewhere, NS use among Ugandan athletes was low. However, determinants of athlete NS use in the current study (category of sport and duration of time spent playing the sport) are similar to those reported elsewhere
The Effects of Manual Therapy and PRIMFIT Unstable Surface Balance Training on Walking Gait Cycle Post an Acute Grade 3 Inversion Ankle Sprain: A Case Study
This case demonstrates the effectiveness of a rehabilitation product and protocol that incorporates manual therapy and unstable surface training. The purpose of this case study was to evaluate the effect of a four-week unstable training protocol using PRIMFIT product in conjunction with manual physical therapy on walking gait in a 17-year old, with grade 3 ankle sprain and multiple ligament tears. A PRIMFIT protocol was designed and performed biweekly under supervision of a physical therapist and also biweekly by the patient independently. Patient\u27s walking gait was tested once a week using an OPTOGAIT System. The patient demonstrated significant clinical and statistical improvements in all gait and time parameters measured by OPTOGAIT system, as well as increased ankle mobility, decreased swelling and markedly decreased pain. For this patient, a combination of manual therapy techniques, PRIMFIT product and rehabilitation exercises were able to significantly improve and normalize walking gait, in addition to eliminating swelling and pain. However, further research is needed with additional cases, especially those with similar or other injuries to develop the efficacy of the PRIMFIT product and protocol
A descriptive prospective study of sports medicine practices for athletes in Uganda
Background: Many international sporting organizations have recommended practices to reduce the risk of injury. These practices include screening for injury, having appropriate emergency medical care, and protocols for managing injury before return-to-play. The extent of the uptake of these practices in a developing country such as Uganda, is unknown.Methodology: Using a descriptive case study approach, this investigation focused on a sample of injured athletes (n = 75) in Uganda from four main sports associations (football, athletics, basketball and rugby). The data were collected through observations and interviews after the injury. Using a best medical practice framework the phases of emergency, intermediate, rehabilitative, and return-to-sports participation were described.Result: Nine conditions/types of injury were included. The results revealed a lack of specific pre-season screening or re- turn-to-play readiness for all the injured athletes. Further, there was a lack of application of best practice principles for most of the injury types. For athletes who received medical care, the results show inconsistencies and inadequacies from the acute stage of the injury to return-to-sports participation.Conclusion: This study identified barriers such as up-to-date knowledge among the sports resource providers; the gaps for appropriate and adequate specific facilities for managing injured athletes, and policies to mandate care of injured athletes. These barriers detract from applying best medical practices
Prevention and Management of Sport-Related Concussions in Uganda: A Case Study
Head injuries in sports often go unnoticed and untreated with a risk of increasing the severity of neurological difficulties for affected athletes. While there is much research on athletes in developed countries, the data on athletes from developing countries is lacking. Using a descriptive case study approach, this report focuses on concussions from four main sports (football, athletics, basketball and rugby). Emphasis was placed on those athletes who had been identified with a sport-related concussion (SRC). The phases of emergency, intermediate, rehabilitative, and return to sports participation were considered in this study. Three SRC cases from both male and female athletes were observed and interviewed for post-injury management from the emergency phase to return to sports participation. There was evidence of lack of specific pre-season screening of athletes for concussion history and standard care for concussed athletes in all the three cases observed using the best medical practice framework. Our study shows barriers such as knowledge among the sports resource providers; a law and policies to mandate care, and the absence of specific facilities for managing athletes with concussions. Implementation of sports health care policies is necessary to mandate care for athletes. Strategies for prevention and management of concussions are necessary, especially through increasing the awareness and knowledge using the Concussion Awareness Training Tool (CATT). Further studies with larger samples are encouraged to ascertain the magnitude of existing barriers
