Health and Related Factors for Sudanese Refugees in Nebraska

Results of a health survey covering demographics, health risk/prevention factors, and barriers to health care among 263 refugees from Sudan, now living in Nebraska, are presented. Data are compared to Nebraska's general and minority populations. Sudanese refugees are generally young, highly mobile, uneducated, and live in poverty. Refugees are proportionally different from other Nebraskans, in terms of risk factors and rates of common U.S. conditions, but are unable to use preventive systems for maintaining high health status. Nearly 40% do not have health or dental insurance, 20% have never visited a dental or eye care professional, and 11% have never been to a doctor. Federal programs should standardize resettlement site screening so that mobile populations can begin the resettlement process healthy and prevent the spread of infectious disease. Good health at the outset will allow more time and resources for education, language, and employment acquisition, all of critical importance to the Sudanese refugee community.

High Prevalence of Antimicrobial Resistance Among Common Bacterial Isolates in a Tertiary Healthcare Facility in Rwanda

Antimicrobial resistance (AMR) is a serious public health threat in both developed and developing countries. Many developing countries, including Rwanda, lack adequate surveillance systems, and therefore, the prevalence of AMR is not well-known. We conducted a prospective observational study to assess the prevalence of AMR among common bacterial isolates from clinical specimens obtained from patients on the medical wards of Kigali University Teaching Hospital (KUTH). We evaluated the antibiotic sensitivity patterns of bacterial pathogens cultured from urine, blood, sputum, and wound swab specimens obtained over a 6-month period (July 1 to December 30, 2013). There were 154 positive cultures from specimens obtained from 141 unique patients over the study period. Urine, blood, wound swab, and sputum cultures comprised 55.2%, 25.3%, 16.2%, and 3.3% of the total specimens evaluated; 31.4% and 58.7% of Escherichia coli and Klebsiella isolates, respectively, were resistant to at least one of the third generation cephalosporins. Eight percent of E. coli isolates were resistant to imipenem; 82% and 6% of Staphylococcus aureus strains were oxacillin- and vancomycin-resistant respectively. Antimicrobial resistance rates are high in Rwanda and pose a serious therapeutic challenge to the management of common infections.     

Distribution and aetiology of blindness and visual impairment in mesoendemic onchocercal communities, Kaduna State, Nigeria. Kaduna Collaboration for Research on Onchocerciasis.

During a field trial of ivermectin in Kaduna State, 6831 people age 5 years and above, living in 34 mesoendemic onchocercal communities in Kaduna State, northern Nigeria, were examined for ocular disease. Visual function assessments included tests of visual acuity and visual fields. A total of 185 individuals (2.7%) were bilaterally blind by acuity criteria with a further 28 blind by field constriction. The overall prevalence of blindness was 3.1%. A further 118 individuals were visually impaired by WHO criteria. Examination for the cause of blindness revealed that 43% of eyes in bilaterally blind patients were blind due to onchocerciasis. A further 11% were blind from optic atrophy much of which was probably onchocercal in origin. Glaucoma was the next most common cause of blindness in the bilaterally blind (11%). Only 6% of eyes were blind from cataract as the primary cause. In the visually impaired population cataract was the most common primary cause of impaired/blind eyes (31%), followed by onchocerciasis (19%) [corrected].

Shortcomings in the Application of Multicolour Flow Cytometry in Lymphocyte Subsets Enumeration

The lymphoid system is composed of numerous phenotypically distinct subsets of cells, each of which has a unique role in the effectiveness of an immune response. To distinguish specifically between these subsets, it is mandatory to detect simultaneously different cell surface antigens. This became feasible by the development of multicolour flow cytometric technologies. With these techniques, researchers now have the opportunity to study individual cells in far greater detail than previously possible. However, proper data analysis, interpretation and presentation of results will require a high level of understanding of the intricacies of the technology and the inherent limitations of the acquired data. The present report is intended to contribute to the better understanding of how the flow cytometer operates. This report may help new and inexperienced users to work appropriately with the flow cytometer.
