Culturally-adapted and audio-technology assisted HIV/AIDS awareness and education program in rural Nigeria: a cohort study

Background: HIV-awareness programs tailored toward the needs of rural communities are needed. We sought to quantify change in HIV knowledge in three rural Nigerian villages following an integrated culturally adapted and technology assisted educational intervention. Methods: A prospective 14-week cohort study was designed to compare short-term changes in HIV knowledge between seminar-based education program and a novel program, which capitalized on the rural culture of small-group oral learning and was delivered by portable digital-audio technology. Results: Participants were mostly Moslem (99%), male (53.5%), with no formal education (55%). Baseline HIV knowledge was low (\u3c 80% correct answers for 9 of the 10 questions). Knowledge gain was higher (p \u3c 0.0001 for 8 of 10 questions) in the integrated culturally adapted and technology-facilitated (n = 511) compared with the seminar-based (n = 474) program. Conclusions: Baseline HIV-awareness was low. Culturally adapted, technology-assisted HIV education program is a feasible cost-effective method of raising HIV awareness among low-literacy rural communities

A bridge between statistics and literature: The graphs of Oscar Wilde's literary genres

The availability of computing devices and the proliferation of electronic texts (the so-called 'e-texts') in centres for literary and linguistic computing in major universities have encouraged non-traditional applications of statistics. With the drudgery of computation and text encoding diminished, research in the field of computational stylistics is accelerating. In this paper, it is shown how projections onto the Cartesian plane of 25-dimensional vectors related to the frequency of occurrence of 25 prepositions can distinguish between Oscar Wilde's plays and essays. Such an application illustrates that it is possible to find unusual and intriguing examples of how statistics can impinge on unexpected territory.

Decreasing Estimated Glomerular Filtration Rate Is Associated With Increased Risk of Hospitalization After Kidney Transplantation

After renal transplantation, decreased renal function is associated with increased risk of cardiovascular disease, graft loss, and mortality. We investigated whether declining renal function was associated with hospitalization after transplantation. Methods: Adult, first-time, kidney transplant recipients between 2004 and 2006 from the United Network for Organ Sharing database and hospitalizations 1 year after the 6-month posttransplant follow-up visit were examined. Generalized linear models explored the relationship between estimated glomerular filtration rate (eGFR) measured at 6 months and the number of hospitalizations in the following year. Results: Of 15,778 kidney transplant recipients, 19.1% were admitted in the year after the 6-month follow-up visit. Among those hospitalized, the mean number of hospitalizations was 1.71, which increased with decreasing eGFR. In multivariable models, a decrease in eGFR was significantly associated with increased hospitalizations: for every 10 ml/min per 1.73 m2 decrease in eGFR, there was an 11% increase in hospitalization rate (P < 0.001). Lower eGFR after the first 6 months after transplantation was associated with an increase in late hospitalizations among adult kidney transplant recipients. Discussion: Identifying patients with declining eGFR and other risk factors may help prevent morbidity and mortality associated with hospitalization after transplantation

Surgical management of symptomatic Tarlov cysts: Cyst fenestration and nerve root imbrication-a single institutional experience.

BackgroundTarlov cyst disease is a collection of cerebrospinal fluid between the endoneurium and perineurium of spinal, usually sacral, nerve roots. These cysts can become symptomatic in 20% of patients, causing lower back pain, radiculopathy, bladder and bowel dysfunction necessitating medical or surgical intervention. Different surgical and non-surgical modalities have been described for the treatment of symptomatic Tarlov cysts. However, there has been no published study that examined types of surgical techniques side by side. Our study presents a preliminary experience in the surgical management of symptomatic Tarlov cysts using two surgical techniques: cyst fenestration and nerve root imbrication.MethodsRetrospective chart review and analysis was done for all patients who underwent surgical intervention for symptomatic Tarlov cyst(s) in the period 2007-2013. Operative reports, preoperative and postoperative clinic visit reports were reviewed. The surgical techniques of cyst fenestration and nerve root imbrication were each described in terms of intraoperative parameters, hospital course and outcome. Modified MacNab criteria were used for evaluation of the final clinical outcome.ResultsThirty-six surgical patients were identified. Three had repeat surgery (total of 39 operations). The median age was 51 years (range, 26-84 years). Eighty-six percent were females. The presenting symptoms were low back pain (94%), sensory radiculopathy (69%), bladder and bowel dysfunction (61%), sexual dysfunction (17%) and motor dysfunction (8%). Cyst fenestration was performed in 12 patients (31%) and nerve root imbrication was done in 27 (69%). All patients in the fenestration group but only 67% in the imbrication group had fibrin glue injection into the cyst or around the reconstructed nerve root. The overall surgery-related complication rate was 28%. The complication rate was 5/12 (42%) in the fenestration group and 6/27 (22%) in the imbrication group. At the time of the last clinic visit, improved clinical outcome was noted in 9/11 (82%) and 20/25 (80%) in the fenestration and the imbrication group, respectively.ConclusionsCyst fenestration and nerve root imbrication are both surgical techniques to treat symptomatic Tarlov cyst(s), and both can result in clinical improvement
