The cascade of HIV care among refugees and nationals in Nakivale Refugee Settlement in Uganda.

OBJECTIVES: Refugees living in Uganda come from HIV-endemic countries, and many remain in refugee settlements for over a decade. Our objective was to evaluate the HIV care cascade in Nakivale Refugee Settlement and to assess correlates of linkage to care. METHODS: We prospectively enrolled individuals accessing clinic-based HIV testing in Nakivale Refugee Settlement from March 2013 to July 2014. Newly HIV-diagnosed clients were followed for 3 months post-diagnosis. Clients underwent a baseline survey. The following outcomes were obtained from HIV clinic registers in Nakivale: clinic attendance ('linkage to HIV care'), CD4 testing, antiretroviral therapy (ART) eligibility, and ART initiation within 90 days of testing. Descriptive data were reported as frequency with 95% confidence interval (CI) or median with interquartile range (IQR). The impact of baseline variables on linkage to care was assessed with logistic regression models. RESULTS: Of 6850 adult clients tested for HIV, 276 (4%; CI: 3-5%) were diagnosed with HIV infection, 148 (54%; CI: 47-60%) of those were linked to HIV care, 54 (20%; CI: 15-25%) had a CD4 test, 22 (8%; CI: 5-12%) were eligible for ART, and 17 (6%; CI: 3-10%) initiated ART. The proportions of refugees and nationals at each step of the cascade were similar. We identified no significant predictors of linkage to care. CONCLUSIONS: Less than a quarter of newly HIV-diagnosed clients completed ART assessment, considerably lower than in other reports from sub-Saharan Africa. Understanding which factors hinder linkage to and engagement in care in the settlement will be important to inform interventions specific for this environment.

United States (US) multi-center study to assess the validity and reliability of the Spinal Cord Independence Measure (SCIM III).

STUDY DESIGN: Multi-center, prospective, cohort study. OBJECTIVES: To assess the validity and reliability of the Spinal Cord Independence Measure (SCIM III) in measuring functional ability in persons with spinal cord injury (SCI). SETTING: Inpatient rehabilitation hospitals in the United States (US). METHODS: Functional ability was measured with the SCIM III during the first week of admittance into inpatient acute rehabilitation and within one week of discharge from the same rehabilitation program. Motor and sensory neurologic impairment was measured with the American Spinal Injury Association Impairment Scale. The Functional Independence Measure (FIM), the default functional measure currently used in most US hospitals, was used as a comparison standard for the SCIM III. Statistical analyses were used to test the validity and reliability of the SCIM III. RESULTS: Total agreement between raters was above 70% on most SCIM III tasks and all κ-coefficients were statistically significant (P<0.001). The coefficients of Pearson correlation between the paired raters were above 0.81 and intraclass correlation coefficients were above 0.81. Cronbach's-α was above 0.7, with the exception of the respiration task. The coefficient of Pearson correlation between the FIM and SCIM III was 0.8 (P<0.001). For the respiration and sphincter management subscale, the SCIM III was more responsive to change, than the FIM (P<0.0001). CONCLUSION: Overall, the SCIM III is a reliable and valid measure of functional change in SCI. However, improved scoring instructions and a few modifications to the scoring categories may reduce variability between raters and enhance clinical utility.

Myoepithelial cells in the differential diagnosis of complex benign and malignant breast lesions: an immunohistochemical study.

The distinction between sclerosing adenosis, radial scars, noninvasive carcinomas occurring in sclerosing adenosis, and invasive carcinoma can be difficult. The identification of a myoepithelial (ME) cell layer is helpful in establishing a diagnosis of complex benign breast proliferation as well as intraepithelial neoplasia in sclerosing adenosis. We reviewed pathologic material from patients with tubular carcinoma (23) and complex breast proliferations (28), including sclerosing adenosis (12), radial scars (9), sclerosing adenosis with intraepithelial neoplasia (5), and sclerosing adenosis with atypical apocrine metaplasia (2). Immunoperoxidase stains on formalin-fixed, paraffin-embedded tissue using a muscle actin-specific antibody of clone HHF35 and high molecular weight cytokeratin of clone 34 beta E12 (HMW keratin) were performed to identify myoepithelial cells. Muscle actin was uniformly reliable in staining ME cells, as well as other actin-containing cells such as myofibroblasts and vascular smooth muscle. HMW keratin was less reliable, being poorly sensitive and less specific than muscle actin for labeling of ME cells. ME cells were readily identified at the periphery of ductules in all complex benign breast lesions. The presence of ME cells distinguished intraepithelial neoplasia involving sclerosing adenosis from invasive carcinomas. Well differentiated invasive carcinoma forming tubular structures lacked a ME cell layer.
