Abstract
INTRODUCTION The expansion of antiretroviral therapy (ART) eligibility could lead to earlier initiation of Human Immunodeficiency Virus (HIV) treatment and consequently reduce the risk of HIV-associated Kaposi Sarcoma (KS). We investigated the impact of changes in the Nigerian HIV treatment guidelines on KS incidence among adults enrolled in HIV care in Nigeria. METHODS We analyzed data of adults who enrolled for HIV care from January 2006 to December 2016 at one of Nigeria's largest HIV treatment centers. Based on changes in HIV treatment guidelines, we classified 2006-2009 as the pre-expansion period and 2010-2016 as the post-expansion period. We used Kaplan Meier curves to compare the incidence of KS in the pre-expansion to the post-expansion period. We used Cox regression models to assess the hazard for incident KS between the two periods after adjusting for potential confounders. RESULTS Among 14,479 patients with HIV, the overall KS incidence was 2.35; 95% CI 2.01-2.74/1,000 person-years. The incidence of KS decreased from 2.53 to 1.58 per 1,000 person-years from 2006 to 2009 to 2010-2016. In models adjusting for age, sex, CD4-T cell count, and ART use, the risk for KS remained lower in 2010-2016 compared to 2006-2009. In analyses restricted to time on ART, there was no significant difference in KS incidence between HIV patients who enrolled in 2006-2009 and 2010-2016 after adjusting for age, sex, and CD4 T-cell count. CONCLUSION The expansion of ART eligibility was associated with a reduced incidence of HIV-associated KS among adults initiating HIV care in Jos, Nigeria. The reduction was likely driven by earlier enrollment for HIV care and ART initiation.

Abstract
Background The incidence of Human Immunodeficiency Virus (HIV)-associated Kaposi Sarcoma (KS) in the pre-antiretroviral therapy (ART) population remains high in several countries in sub-Saharan Africa. We examined trends of KS prevalence in adults, establishing initial outpatient HIV care from 2006 to 2017 in Nigeria. Methods We analyzed data of 16,431 adults (age ≥ 18 years) enrolled for HIV care from January 1, 2006, to December 31, 2017, in a large clinic in Jos, Nigeria. KS at enrollment was defined as KS recorded in the electronic health record within 30 days of clinic enrollment. Time trends were compared among four periods: 2006–2008, 2009–2011, 2012–2014, and 2015–2017 using logistic regression models. Annual trends were analyzed using join point regression and restricted splines. Results The study population had a mean age 35.1 (standard deviation, SD 9.5) years, and were 65.7% female (n = 10,788). The mean CD4 cell count was 220 (95% CI 117–223). The overall KS prevalence at entry was 0.59% (95% CI 0.48–0.72). Compared to 2006–2008, KS prevalence was significantly higher in 2009–2011 (adjusted odds ratio 5.07 (95% CI 3.12–8.24), p < 0.001), but remained unchanged in subsequent periods. Male sex and low CD4 T-cell count independently increased odds for KS. Conclusions Despite ART expansion, KS at enrollment showed no significant decline. The low CD4 cell count, across all periods, indicates delay in enrollment for HIV care, which increases KS risk. Interventions aimed at early HIV diagnosis and linkage to ART is critical to KS risk reduction in this population.

Abstract
Aims Employers in the United States incur substantial costs associated with substance use disorders. Our goal was to examine the effectiveness of employer‐led interventions to reduce the adverse effects of drug misuse in the workplace. Methods We conducted a systematic review of studies that evaluated the effectiveness of recommended workplace interventions for opioids and related drugs: employee education, drug testing, employee assistance programs, supervisor training, written workplace drug‐free policy, and restructuring employee health benefit plans. We searched PubMed MEDLINE, EMBASE (embase.com), PsycINFO (Ebsco), ABI Inform Global, Business Source Premier, EconLit, CENTRAL, Web of Science (Thomson Reuters), Scopus (Elsevier), Proquest Dissertations, and Epistemonikos from inception through May 8, 2019, with no date or language restrictions. We included randomized controlled trials, quasi‐experimental studies, and cross‐sectional studies with no language or date restrictions. The Downs and Black questionnaire was used to assess the quality of included studies. The results were reported using the Preferred Reporting Items for Systematic Reviews and Meta‐Analysis (PRISMA) guidelines. Results In all, 27 studies met our inclusion criteria and were included in the systematic review. Results were mixed, with each intervention shown to be effective in at least one study, but none showing effectiveness in over 50% of studies. Studies examining the impact of interventions on workplace injuries or accidents were more commonly reported to be effective. Although four studies were randomized controlled trials, the quality of all included studies was “fair” or “poor.” Conclusions Despite the opioid epidemic, high‐quality studies evaluating the effectiveness of employer‐led interventions to prevent or reduce the adverse effects of substance use are lacking. Higher quality and mixed methods studies are needed to determine whether any of the interventions are generalizable and whether contextual adaptations are needed. In the meantime, there is a reason to believe that commonly recommended, employer‐led interventions may be effective in some environments.

Abstract
HIV-1 compartmentalization in the central nervous system (CNS) and its contribution to neurological disease have been well documented. Previous studies were conducted among people infected with subtypes B or C where CNS compartmentalization has been observed when comparing viral sequences in the blood to virus in cerebrospinal fluid (CSF). However, little is known about CNS compartmentalization in other HIV-1 subtypes. Using a deep sequencing approach with Primer ID, we conducted a cross-sectional study among Nigerian and Malawian HIV-1 cohorts with or without fungal Cryptococcus infection diagnosed as cryptococcal meningitis (CM) to determine the extent of CSF/CNS compartmentalization with CM. Paired plasma and CSF samples from 45 participants were also analyzed for cytokine/chemokine levels. Viral populations comparing virus in the blood and the CSF ranged from compartmentalized to equilibrated, including minor or partial compartmentalization or clonal amplification of a single viral sequence. The frequency of compartmentalized viral populations in the blood and CSF was similar between the CM- and CM+ participants. We confirmed the potential to see compartmentalization with subtype C infection and have also documented CNS compartmentalization of an HIV-1 subtype G infection. Cytokine profiles indicated a proinflammatory environment, especially within the CSF/CNS. However, sCD163 was suppressed in the CSF in the presence of CM, perhaps due to elevated levels of IL-4, which were also a feature of the cytokine profile, showing a distinct cytokine profile with CM.

Abstract
Background The presence of human leukocyte antigen (HLA) B*57:01 allele predicts hypersensitivity reaction (HSR) to abacavir (ABC), a nucleoside reverse-transcriptase inhibitor used for human immunodeficiency virus (HIV) treatment. However, the prevalence of this allele amongst Nigerians with HIV is yet to be established. We aimed to determine the prevalence of HLA-B*57:01 allele amongst Nigerians with HIV infection. Methods We conducted a multicentre cross-sectional epidemiologic survey. Between April 2016 and April 2017, patients were enrolled across five HIV treatment facilities in Nigeria. Participants' demographic information and their history of ABC exposure were obtained, and venous blood was obtained for HLA typing. Results One thousand five hundred and four (1504) adults were enrolled, with a mean age of 44.6 ± 10.7 years, 1078 (71.7%) were female. 1463 (97.3%) were on antiretroviral therapy. ABC use was reported by 12 (0.8%) participants and none reported HSR. Of 1500 blood samples that were processed, 1458 (97.2%) were successfully typed. Of these, 132 (9.1%) were HLA-B*57 positive using non-specific low-resolution HLA-B*5701 primer mix. On further analysis, none of the 132 samples (0%) had the HLA-B*5701 allele. Conclusion HLA-B*5701allele is rare amongst Nigerians.

Abstract
BACKGROUND Factors associated with tobacco smoking are useful in designing tobacco control programs. OBJECTIVES To estimate the prevalence of and factors associated with tobacco smoking among long-distance drivers. METHODS A cross-sectional study. Stratified cluster sampling approach was used to select drivers based on if they received annual health screening (AHS) or not (non-AHS). We used a structured questionnaire to obtain information and weighted the resulting observations to derive population based estimates. Association between tobacco smoking and socio-demographic factors was explored in multivariate models. RESULTS A total of 414 male drivers, with a mean age of 43.6 (standard error 0.6) years were studied. Population weighted prevalence of current smoking was 18.9% (95% CI: 14.3-23.4) all drivers, 6.5% (95% CI: 2.6-10.4) of AHS drivers and 19.5 (95% CI: 14.7-24.2) of non-AHS drivers (p<0.001). In multivariate models, having close friends that smoked (OR= 6.36, 95% CI= 2.49 - 16.20) cargo driving (OR= 2.58, 95% CI= 1.29 - 5.15) and lower education levels (OR for post-secondary education vs. Primary education or less= 0.17, 95% CI= 0.04 - 0.81) were associated with current smoking. CONCLUSION Prevalence of tobacco smoking is higher among non-AHS compared to AHS drivers. Having close friends that smoked, cargo driving, and lower education levels were associated with current smoking.

Abstract
Background The contribution of obesity to obstructive sleep apnea (OSA) is poorly described in Nigeria. We aimed to compare OSA risk between obese and nonobese adults in urban Nigeria. Materials and Methods An analytic cross-sectional study was conducted. Participants were interviewed using the World Health Organization Non-Communicable Disease questionnaire. OSA risk assessment was performed using the STOP-BANG questionnaire. A total score of ≥3 on the STOP-BANG questionnaire indicated OSA risk, whereas a score ≥5 indicated high OSA risk. Obesity was defined as body mass index (BMI) >30 kg/m2. Relationship between obesity and OSA was tested using chi-square and logistic regression models used to control for confounding factors. Results There were 744 respondents, with a mean age of 44 (standard deviation 10) years. A total of 206 [27.7%, 95% confidence interval (CI) 24.46–30.9] respondents were obese (BMI ≥30 kg/m2). A total of 307 (41.3%, 95% CI 37.7–44.9) respondents scored ≥3 on the STOP-BANG questionnaire, whereas 37 (4.9%, 95% CI 3.6–6.7) scored ≥5. More number of obese than nonobese [57.8% (119/206) versus 34.9% (188/538)] respondents met the criteria for OSA risk (P < 0.001). Similarly, more obese persons [10.3% (21/206)] met the criteria for high-risk OSA compared to the nonobese [3% (16/538)]; P < 0.001. In logistic regression models adjusted for cigarette smoking and alcohol consumption, the odds for OSA risk was 15.76 (95% CI 7.44–33.9) in persons with BMI >35 kg/m2 compared to those with a BMI range of 18.5–24.99. Conclusion Obesity and OSA may be more prevalent in Nigeria than previously predicted. Obesity independently increased OSA risk in this population.

Abstract
Background The incidence of non-communicable diseases(NCDs) is rising globally, with its attendant morbidity andmortality, especially in developing countries. This study evaluatedthe prevalence of NCDs and their risk factors amongmembers of a university community. Methods All employees of the university were invited to the University health clinic for screening, using the World Health Organisation’s STEPwise approach to NCDs. Results A total of 883 (521; 59.0% males) employees with a mean age of 44 ± 10 years were studied. The median (IQR) number of NCD risk factors was three (two to three) per participant. The most common NCD risk factors were inadequate intake of fruit and vegetables (94.6%; 95% CI: 92.8–95.9), physical inactivity (77.8%; 95% CI: 74.9–80.5%) and dyslipidaemia (51.8%; 95% CI: 48.4–51.6%). Others included obesity (26.7%; 95% CI: 23.9–29.8%), alcohol use (24.0%; 95% CI: 21.3–27.0%) and cigarette smoking (2.9%; 95% CI: 2.0–4.3). Hypertension was the most common NCD (48.5%; 95% CI: 45.1–51.8%), followed by chronic kidney disease (13.6%; 95% CI: 11.4–16.1) and diabetes mellitus (8.0%; 95% CI: 6.4–10.1). There was no gender-specific difference in the prevalence of NCDs. Conclusion This study identified that NCDs and their modifiable risk factors are highly prevalent in this community. Workplace policy to support the adoption of healthy living is needed.

Abstract
BACKGROUND Lymphoma is a leading cause of cancer-related death among human immunodeficiency virus (HIV)-infected individuals in the current era of potent anti-retroviral therapy (ART). Globally, mortality after HIV-associated lymphoma has profound regional variation. Little is known about HIV-associated lymphoma mortality in Nigeria and other resource-limited setting in sub-Saharan Africa. Therefore, we evaluated the all-cause mortality after lymphoma and associated risk factors including HIV at the Jos University Teaching Hospital (JUTH) Nigeria. METHODS We conducted a ten-year retrospective cohort study of lymphoma patients managed in JUTH. The main outcome measured was all-cause mortality and HIV infection was the main exposure variable. Overall death rate was estimated using the total number of death events and cumulative follow up time from lymphoma diagnosis to death. Cox proportional hazard regression was used to assess factors associated with mortality after lymphoma diagnosis. RESULTS Out of 40 lymphoma patients evaluated, 8(20.0%) were HIV positive and 32(80.0%) were HIV negative. After 127.63 person- years of follow-up, there were 16 deaths leading to a crude mortality rate of 40.0 per 100 person-years. The 2-year probability of survival was 30% for HIV-infected patients and 74% for HIV-uninfected. Median survival probability for HIV-infected patients was 2.1 years and 7.6 years for those without HIV. Unadjusted hazard of death was associated with late stage, HR 11.33(95% CI 2.55, 50.26,p = 0.001); low cumulative cycles of chemotherapy, HR 6.43(95% CI 1.80, 22.89,p = 0.004); greater age, HR 5.12(95% CI 1.45,18.08,p = 0.01); presence of comorbidity, HR 3.43(95% CI 1.10,10.78,p = 0.03); and HIV-infection, HR 3.32(95% CI 1.05, 10.51,p = 0.04). In an adjusted model only stage was significantly associated with death, AHR 5.45(1.14-26.06, p = 0.03). CONCLUSION Our findings suggest that HIV- infection accounted for three times probability of death in lymphoma patients compared to their HIV-uninfected counterparts due to late stage of lymphoma presentation in this population. Also initiation of chemotherapy was associated with lower probability of death among lymphoma patients managed at JUTH, Nigeria. Earlier stage at lymphoma diagnosis and prompt therapeutic intervention is likely to improve survival in these patients. Future research should undertake collaborative studies to obtain comprehensive regional data and identify unique risk factors of poor outcomes among HIV-infected patients with lymphoma in Nigeria.

Abstract
Background Although erectile dysfunction (ED) is common, little is known about the impact of ED on the quality of life (QoL) among African men. Materials and Methods We used the International Index of Erectile Function (IIEF) to evaluate ED and the WONCA charts to assess QoL among employees of a university. Results A total of 508 men with a mean age of 43 ± 10 years were studied. IIEF5 scores of <22 were present in 406 participants (77.9%). Mild ED, mild-to-moderate ED, moderate ED, and severe ED were present in 34.6%, 26.6%, 10.4%, and 5.7%, respectively. Systolic and diastolic blood pressure were significantly lower in those with ED. Marital status, alcohol, cigarette, physical inactivity, obesity, hypertension, diabetes mellitus, and antihypertensive drug use were not associated with ED. ED was associated with poor QoL in the domains of social activities (odds ratio [OR] = 4.35; 95% confidence interval [CI]: 1.01-18.7), and overall health (OR = 2.27; 95% CI: 1.07-4.82). However, there was no association of ED with poor QoL in the domains of physical fitness (OR = 1.46; 95% CI: 0.82-2.59), feelings (OR = 1.43; 95% CI: 0.75-2.72), daily activities (OR = 4.72; 95% CI: 0.61-36.4), and change in health (OR = 1.75; 95% CI: 0.58-5.26). Conclusion ED negatively impacts QoL in men.

Abstract
OBJECTIVE To determine the prevalence and risk factors for chronic obstructive pulmonary disease (COPD) among HIV-infected adults in Nigeria. DESIGN Cross-sectional study. METHODS HIV-infected adults aged ≥ 30 years with no acute ailments accessing care at the antiretroviral therapy clinic of Jos University Teaching Hospital were enrolled consecutively. Participants were interviewed to obtain pertinent demographic and clinical information, including exposure to risk factors for COPD. Post-bronchodilator spirometry was carried out. HIV related information was retrieved from the clinic medical records. COPD case-definition was based on the Global Initiative for Obstructive Lung Disease (GOLD) criteria using post-bronchodilator FEV1/FVC <0.7. COPD prevalence was also calculated using the lower limit of normal for FEV1/FVC criteria (LLN) from the European Respiratory Society normative equation. Factors associated with COPD were determined using logistic regression models. RESULTS Study population comprised 356 HIV infected adults with mean age of 44.5 (standard deviation, 7.1) years and 59% were female. The mean time elapsed since HIV diagnosis was 7.0 (SD, 2.6) years and 97.5% of the respondents were on stable ART with virologic suppression present in 67.2%. Prevalence of COPD were 15.4% (95% confidence interval [CI] 11.7-19.2), 12.07% (95% CI 8.67-15.48), 22.19% (95% CI 18.16-26.83) using GOLD, ERS LLN and GLI LLN diagnostic criteria respectively. In multivariate analyses adjusting for gender, exposure to cigarette smoke or biomass, history of pulmonary tuberculosis, use of antiretroviral therapy, current CD4 T-cell count and HIV RNA, only age > 50 years was independently associated with COPD with OR 3.4; 95% CI 1.42-8.17 when compared to ages 30-40 years. CONCLUSION HIV-associated COPD is common in our population of HIV patients.

Abstract
BACKGROUND The burden of obstructive sleep apnea among commercial drivers in Nigeria is not known. AIM To assess the prevalence of high risk of obstructive sleep apnea (OSA) and excessive daytime sleepiness (EDS) among intra-city commercial drivers. SETTING AND DESIGN A descriptive cross-sectional study in three major motor parks in Lagos metropolis. MATERIALS AND METHODS Demographic, anthropometric and historical data was obtained. The risk of OSA and EDS was assessed using the STOP BANG questionnaire and the Epworth Sleepiness Scale, respectively. STATISTICAL ANALYSIS The relationship between the OSA risk, EDS risk and past road traffic accident (RTA) was explored using the Pearson's chi square. Independent determinants of OSA risk, EDS risk and past RTA, respectively, were assessed by multiple logistic regression models. RESULT Five hundred male commercial drivers (mean age (years) ±SD = 42.36 ± 11.17 and mean BMI (kg/m(2)) ±SD = 25.68 ± 3.79) were recruited. OSA risk was high in 244 (48.8%) drivers and 72 (14.4%) had EDS. There was a positive relationship between OSA risk and the risk of EDS (Pearson's X(2) = 28.2, P < 0.001). Sixty-one (12.2%) drivers had a past history of RTA but there was no significant relationship between a past RTA and either OSA risk (X(2) = 2.05, P = 0.15) or EDS risk (X(2) = 2.7, P = 0.1), respectively. Abdominal adiposity, regular alcohol use and EDS were independent determinants of OSA risk while the use of cannabis and OSA risk were independent determinants of EDS. No independent risk factor for past RTA was identified. CONCLUSION A significant proportion of commercial drivers in Lagos metropolis are at high risk of OSA and EDS.

Abstract
Data on baseline hepatic function of HIV and hepatitis B virus (HBV) co-infected patients are limited in sub-Saharan Africa. We assessed liver function test (LFT) abnormalities in Nigerian patients with HIV/HBV co-infection to highlight the impact of HIV on HBV-related liver disease in sub-Saharan Africa. A cross-sectional study involving 100 HIV/HBV co-infected patients and 100 age- and sex-matched HBV mono-infected controls. Blood testing for HIV antibodies, CD4+ cell count, hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg), LFTs, platelet count, fasting blood glucose and lipid profile were carried out. Non-invasive hepatic fibrosis scores (aspartate aminotransferase-platelet ratio index [APRI] and FIB-4) were also calculated. Co-infected patients had deranged liver enzymes more than the controls (77% versus 64%, P = 0.04). The predominant patterns of enzyme derangement in co-infected patients were either predominantly ↑ALP (30% versus 4%, P < 0.0001) or mixed (30% versus 15%, P = 0.01) but predominantly ↑AST/ALT in the controls (25% versus 9%, P = 0.003). Co-infected patients had higher fibrosis scores for both APRI (P = 0.002) and FIB-4 (P = 0.0001). On further analysis, LFT abnormalities and fibrosis scores were only significantly higher in co-infected patients in the immune clearance and HBeAg-negative chronic hepatitis phases. LFT abnormalities are common in Nigerians with HBV infection and co-infection with HIV negatively impacts on hepatic function.

Abstract
Our objective was to determine tuberculosis (TB) incidence and evaluate TB risk in adults after one or more years of use of combination antiretroviral therapy (cART) through a retrospective cohort study in Jos, Nigeria. We studied a cohort of HIV-infected adults treated with ART for at least 1 year. Based on immunologic and virologic responses to ART, patients were categorized into four groups: CD4 T cell count ≥350 cells/mm(3) and HIV-1 RNA level ≤400 copies/ml (group 1), CD4 T cell count ≥350 cells/mm(3) and HIV-1 RNA level >400 copies/ml (group 2), CD4 T cell count <350 cells/mm(3) and HIV-1 RNA level ≤400 copies/ml (group 3), and CD4 T cell count <350 cells/mm(3) and HIV-1 RNA level >400 copies/ml (group 4). Time to incident TB for the four groups was analyzed using the Kaplan-Meier method. Cox regression models were used to evaluate predictors of incident TB. In this cohort of 5,093 HIV-infected adults, of which 68.4% were female, with a mean age 35.1 years (standard deviation 9.1 years), we observed 98 cases of incident TB during 4 years and 3 months of follow-up. The overall TB incidence rate was 8.7 cases/1,000 patient-years of follow-up. Adjusted hazards for incident TB were 2.11 (95% CI 0.97-4.61), 2.05 (95% CI 1.10-3.79), and 3.65 (95% CI 1.15-5.06) in group 2, 3, and 4 patients, respectively, compared to group 1. Tuberculosis incidence in patients on ART is driven by poor immunologic and/or virologic response. Optimization of HIV treatment should be prioritized to reduce the burden of TB in this high-risk population.

Abstract
Background: To determine the level of awareness and knowledge of HIV postexposure prophylaxis (HIV PEP) and determinants of adequate knowledge among Family Physicians in Nigeria. Materials and Methods: This was a cross-sectional questionnaire-based survey conducted among 175 Family Physicians at two national conferences. Results: Majority (97.7%) of the respondents was aware of the concept of HIV PEP and 99.4% believed it was effective in preventing HIV transmission. Over two third of our respondents had been exposed to NSI; however, less than 25% of those exposed received PEP. There was high level of knowledge of the various high-risk body fluids as well as types of high-risk exposures. 93.9% of our respondents knew that HIV PEP should commence within 1 h of exposure, 83.3% knew the correct duration of HIV PEP, but only 57.0% knew the ideal PEP regimen for high-risk exposures. The total mean score for our respondents was 17.8±2.9 with 79.4% having an adequate score. Being a junior doctor and male sex were associated with adequate knowledge. Conclusion: This study shows that despite high levels of awareness and knowledge of HIV PEP, access to its use among family physicians in Nigeria is still sub-optimal.

Abstract
INTRODUCTION The combination of two nucleoside/nucleotide reverse transcriptase inhibitors (N(t)RTIs) and a third agent from another antiretroviral class is currently recommended for initial antiretroviral therapy. In general, N(t)RTIs remain relevant in subsequent regimens. There are currently six nucleoside reverse transcriptase inhibitors and one nucleotide reverse transcriptase inhibitor drug entities available, and several formulations that include two or more N(t)RTIs in a fixed-dose combination. These entities have heterogeneous pharmacological and clinical properties. Accordingly, toxicity, pill burden, dosing frequency, potential drug-drug interaction, preexisting antiretroviral drug resistance and comorbid conditions should be considered when constructing a regimen. This approach is critical in order to optimize virologic efficacy and clinical outcomes. AREAS COVERED This article reviews N(t)RTI combinations used in the treatment of HIV-infected adults. The pharmacological properties of each N(t)RTI, and the clinical trials that have influenced treatment guidelines are discussed. EXPERT OPINION It is likely that N(t)RTIs will continue to dominate the global landscape of HIV treatment and prevention, despite emerging interest in N(t)RTI-free combination therapy. Clinical domains where only few alternatives to N(t)RTIs exist include treatment of HIV/HBV coinfection and HIV-2. There is a need for novel N(t)RTIs with enhanced safety and resistance profiles compared with current N(t)RTIs.

Abstract
BACKGROUND The Electronic Health Record (EHR) is a key component of medical informatics that is increasingly being utilized in industrialized nations to improve healthcare. There is limited information on the use of EHR in sub-Saharan Africa. This paper reviews availability of EHRs in sub-Saharan Africa. METHODS Searches were performed on PubMed and Google Scholar databases using the terms 'Electronic Health Records OR Electronic Medical Records OR e-Health and Africa'. References from identified publications were reviewed. Inclusion criterion was documented use of EHR in Africa. RESULTS The search yielded 147 publications of which 21papers from 15 sub-Saharan African countries documented the use of EHR in Africa and were reviewed. About 91% reported use of Open Source healthcare software, with OpenMRS being the most widely used. Most reports were from HIV related health centers. Barriers to adoption of EHRs include high cost of procurement and maintenance, poor network infrastructure and lack of comfort among health workers with electronic medical records. CONCLUSION There has been an increase in the use of EHRs in sub-Saharan Africa, largely driven by utilization by HIV treatment programs. Penetration is still however very low.

Abstract
BACKGROUND Cryptococcal meningitis (CM) is the most common severe life threatening fungal infection in AIDS patients. It is an important cause of morbidity and mortality There is paucity of data on the prevalence of CM in Nigeria. We aimed to determine the frequency of CM, the clinical presentation and immunological profile. METHODS A cross sectional study was carried out at the Jos University Teaching Hospital (JUTH). A total of 100 HIV-1 infected patients suspected of having meningitis or meningoencephalitis were subjected to cerebrospinal fluid (CSF) analysis (including Indian ink preparation and fungal culture by conventional methods) and CD4 count was determined using flow cytometry (count bit Y-R 1004 Partec Muster Germany). RESULTS The freguency of CM was 36% in our cohort. The commonest clinical presentation included headache (100.0%), neck stiffness (77.8%), fever (72.0%), vomiting 55.6%), personality changes (55.6%), photophobia (27.8%) and convulsions (27.8%). The mean duration of symptoms was 24 +/- 22 days with a median of 17 days. The mean CD4 count was 89 +/- 60 cells/mm3 with a median of 82 cells/mm3. CONCLUSION The high prevalence of CM and the associated severe immunosuppression underscores the importance of early diagnosis of HIV infection which may reduce the incidence of CM. There is the urgent need for access to Amphotericin B and fluconazole in resource constrained settings in addition to a wide access to HAART.

Abstract
This is a report of a Royal College of Physicians-sponsored study visit to the U.K. The 'Taking knowledge overseas' scheme enables promising, talented and motivated physicians to have access to high-quality postgraduate educational experience early in their career which will stimulate learning and encourage them to share good practice and knowledge on their return home. By the end of 2008, 26 doctors from low-income countries had benefited from the programme.
