Decreased chloramphenicol clearance in malnourished Ethiopian children

Summary The disposition of chloramphenicol and chloramphenicol monosuccinate has been studied in thirty-four Ethiopian children of varying nutritional status.After a single intravenous dose corresponding to chloramphenicol 25 mg per kg bodyweight, the plasma clearance of chloramphenicol monosuccinate was decreased only in severely malnourished children with kwashiorkor. Seventeen % of the dose (range 0–51%) was recovered in urine as intact prodrug, indicating incomplete and variable bioavailability of chloramphenicol.Compared to underweight children, on average marasmic and kwashiorkor subjects exhibited a 2- and 3-fold increase, respectively, in the AUC of chloramphenicol. Elevated AUCs could be traced to reduced hepatic clearance of the drug. The unbound fraction both of chloramphenicol and its prodrug were slightly elevated in serum from kwashiorkor subjects.The possibility of using a single point measurement of plasma chloramphenicol as a guide to individualized dosage are discussed.     

A rural Ethiopian population undergoing epidemiological transition over a generation: Butajira from 1987 to 2004

AIMS: To describe the epidemiological development of a rural Ethiopian population from 1987 to 2004 in terms of mortality and associated sociodemographic factors. METHODS: A rural population comprising 10 communities was defined in 1987 and has since been followed by means of regular household visits. After an initial census, births, deaths and migration events were recorded, together with key background factors, on an open cohort basis. Over 97,000 individuals were observed during a total of over 700,000 person years. RESULTS: The initial population of 28,614 increased by an average of 3.64% annually to 54,426 from 1987 to 2004, and also grew older on average. Birth and mortality rates fell, but were still subject to short-term variation due to external factors. Overall mortality was 13.5 per 1000 person years. Increasing mortality in some adult age groups was consistent with increasing AIDS-related deaths, but a new local hospital in 2002 may have contributed to later falls in overall mortality. Sex, age group, time period, literacy, water source, house ownership and distance to town were all significantly associated with mortality differentials. CONCLUSIONS: This population has undergone a complex epidemiological transition during a generation. Detailed long-term surveillance of this kind is essential for describing such processes. Many factors that significantly affect mortality cannot be directly controlled by the health sector and will only improve with general development.     

Surgery in global health delivery

Surgical conditions account for a significant portion of the global burden of disease and have a substantial impact on public health in low- and middle-income countries. This article reviews the significance of surgical conditions within the context of public health in these settings, and describes selected approaches to global surgery delivery in specific contexts. The discussion includes programs in global trauma care, surgical care in conflict and disaster, and anesthesia and perioperative care. Programs to develop surgical training in Botswana and pediatric surgery through international partnership are also described, with a final review of broader approaches to training for global surgical delivery. In each instance, innovative solutions, as well as lessons learned and reasons for program failure, are highlighted.     

Frequency of visits to health facilities and HIV services offered to men,Malawi

ObjectiveTo determine how often men in Malawi attend health facilities and if testing for human immunodeficiency virus (HIV) is offered during facility visits.MethodsWe conducted a cross-sectional, community-representative survey of men (15–64 years) from 36 villages in Malawi. We excluded men who ever tested HIV-positive. Primary outcomes were: health facility visits in the past 12 months (for their own health (client visit) or to support the health services of others (guardian visit)); being offered HIV testing during facility visits; and being tested that same day. We disaggregated all results by HIV testing history: tested ≤ 12 months ago, or in need of testing (never tested or tested > 12 months before).FindingsWe included 1116 men in the analysis. Mean age was 34 years (standard deviation: 13.2) and 55% (617/1116) of men needed HIV testing. Regarding facility visits, 82% (920/1116) of all men and 70% (429/617) of men in need of testing made at least one facility visit in the past 12 months. Men made a total of 1973 visits (mean two visits): 39% (765/1973) were as guardians and 84% (1657/1973) were to outpatient departments. Among men needing HIV testing, only 7% (30/429) were offered testing during any visit. The most common reason for not testing was not being offered services (37%; 179/487).ConclusionMen in Malawi attend health facilities regularly, but few of those in need of HIV testing are offered testing services. Health screening services should capitalize on men’s routine visits to outpatient departments as clients and guardians.     

Intimate partner violence against women in western Ethiopia: prevalence, patterns, and associated factors

Background

Workplace health programs have demonstrated improvements in a number of risk factors for chronic disease. However, there has been little investigation of participant characteristics that may be associated with change in risk factors during such programs. The aim of this paper is to identify participant characteristics associated with improved waist circumference (WC) following participation in a four-month, pedometer-based, physical activity, workplace health program.

Methods

762 adults employed in primarily sedentary occupations and voluntarily enrolled in a four-month workplace program aimed at increasing physical activity were recruited from ten Australian worksites in 2008. Seventy-nine percent returned at the end of the health program. Data included demographic, behavioural, anthropometric and biomedical measurements. WC change (before versus after) was assessed by multivariable linear and logistic regression analyses. Seven groupings of potential associated variables from baseline were sequentially added to build progressively larger regression models.

Results

Greater improvement in WC during the program was associated with having completed tertiary education, consuming two or less standard alcoholic beverages in one occasion in the twelve months prior to baseline, undertaking less baseline weekend sitting time and lower baseline total cholesterol. A greater WC at baseline was strongly associated with a greater improvement in WC. A sub-analysis in participants with a 'high-risk' baseline WC revealed that younger age, enrolling for reasons other than appearance, undertaking less weekend sitting time at baseline, eating two or more pieces of fruit per day at baseline, higher baseline physical functioning and lower baseline body mass index were associated with greater odds of moving to 'low risk' WC at the end of the program.

Conclusions

While employees with 'high-risk' WC at baseline experienced the greatest improvements in WC, the other variables associated with greater WC improvement were generally indicators of better baseline health. These results indicate that employees who started with better health, potentially due to lifestyle or recent behavioural changes, were more likely to respond positively to the program. Future health program initiators should think innovatively to encourage all enrolees along the health spectrum to achieve a successful outcome.     

The Sub-Saharan Africa Regional Partnership (SHARP) for Mental Health Capacity Building: a program protocol for building implementation science and mental health research and policymaking capacity in Malawi and Tanzania

Worldwide, people with mental disorders are detained within the justice system at higher rates than the general population and often suffer human rights abuses. This review sought to understand the state of knowledge on the mental health of people detained in the justice system in Africa, including epidemiology, conditions of detention, and interventions. We included all primary research studies examining mental disorders or mental health policy related to detention within the justice system in Africa. 80 met inclusion criteria. 67% were prevalence studies and meta-analysis of these studies revealed pooled prevalence as follows: substance use 38% (95% CI 26–50%), mood disorders 22% (95% CI 16–28%), and psychotic disorders 33% (95% CI 28–37%). There were only three studies of interventions. Studies examined prisons (46%), forensic hospital settings (37%), youth institutions (13%), or the health system (4%). In 36% of studies, the majority of participants had not been convicted of a crime. Given the high heterogeneity in subpopulations identified in this review, future research should examine context and population-specific interventions for people with mental disorders.     

High-risk behaviours and associated factors among HIV-positive individuals in clinical care in southwest Ethiopia

A hospital-based cross-sectional survey was conducted among 705 HIV-positive individuals. The result showed that 24% of the participants reported unprotected intercourse in their most recent sexual episode. Nine percent of these events were with partners perceived to be HIV-negative and 39% with those of unknown HIV status. Protected sex at recent episode was independently associated with knowing a partner's HIV status, disclosing HIV status to a partner, receipt of antiretroviral treatment and perceiving HIV as less stigmatizing. This highlights the need for interventions among HIV-positive individuals that will assist them in attaining and maintaining safer sex practices.     

Indirect costs associated with accessing eye care services as a barrier to service use in Ethiopia

BACKGROUND: The prevalence of blindness and visual impairment are high in Ethiopia and use of services is limited. Determining the barriers to use of eye care services is critical for planning strategies to prevent blindness. METHODS: A population-based survey of the magnitude and causes of blindness and visual impairment in adults 40 years and older in the Gurage Zone, central Ethiopia was conducted. Among those individuals who had binocular or monocular vision <6/18, an interview to assess use of eye care services and reasons for a failure to use such services was undertaken. RESULTS: Of 850 adults with visual impairment or blindness, 802 were interviewed. Cataract surgery accounted for the primary service currently needed by the blind, followed by trichiasis surgery; service needs were higher for women than for men. Use of services (27.8% of sample) was associated with being male, binocular vision loss, and blindness. The primary reason for a failure to use eye care services were indirect costs (overall, reported by 40% of respondents) associated with accessing the service. There were significant differences between men and women in the reasons for not using the services and between cataract and trichiasis cases but not when comparing binocular vs. monocular conditions, or patients with visual impairment vs. blindness. CONCLUSION: The majority of the causes of visual impairment and blindness are treatable (cataract) or preventable (trachomatous trichiasis). The main barrier for seeking service is related to the indirect medical costs of the service. This suggests that efforts are needed to create mechanisms that 'bridge' communities and eye care facilities. A holistic approach that deals both with the organization of services and the sociocultural factors in communities that affect use is needed. The organization of trichiasis surgery at peripheral health centres and screening programmes which identify and facilitate transport to hospital for cataract patients is one approach. The indirect burden of accessing eye care on the family may be lessened by encouraging patients to have surgery earlier (before they require assistance to reach the hospital), and by improving the efficiency of existing services. Promotion of services must be gender-sensitive, ensuring that specific characteristics of the sociocultural roles of women be considered in order to improve uptake among women. Training and placement of cataract surgeons in rural hospitals would also enhance provision of eye care for the rural population.
