Understanding the epidemiological HIV risk factors and underlying risk context for youth residing in or originating from the Middle East and North Africa (MENA) region: A scoping review of the literature.

INTRODUCTION: HIV is the second leading cause of death among young people globally, and adolescents are the only group where HIV mortality is not declining. Middle East and North Africa (MENA) is one of few regions seeing rapid increase of HIV infections (31.0%) since 2001. MENA youth are at particular risk of HIV due to dearth of research and challenges in accessing services. OBJECTIVE: The purpose of this scoping review is to establish the epidemiological HIV risk factors and underlying risk context for youth residing in or originating from the MENA region. METHODS: Online database searches were conducted using combination of search terms. Screening 5,853 citations, published between 1990-2019 with age groups 16 to 29, resulted in 57 studies included across 18 MENA countries. RESULTS: 'Key populations' engage in risky behaviors, including: overlapping risky behaviors among youth who inject drugs (PWID); lack of access to HIV testing, condomless sex, and multiple sex partners among young men who have sex with men (MSM); and high and overlapping risk behaviors among young sex workers. Challenges facing other youth groups and bridging populations include: peer pressure, inhibition about discussing sexual health, lack of credible sex education sources, low condom use, and lack of access to HIV protection/prevention services, especially testing. CONCLUSION: Poor surveillance coupled with scarcity of rigorous studies limit what is known about epidemiology of HIV among youth in MENA. Homophobia, stigma around PWID, and illegal status of sex work promote non-disclosure of risk behaviors among youth and curtail serving this population.

Utilizing public health core competencies to share data effectively with community organizations to promote health equity.

OBJECTIVES: This article utilizes an adapted model for research transfer to highlight the important role of Local Public Health Agencies (LPHAs) to share data more effectively with local community organizations to advance health equity. METHODS: A literature review related to public health data sharing with local community partners was conducted using Medline, Embase, and CINAHL databases and grey literature sources with 12 articles included for analysis. Six LPHAs distributed an online survey to 405 local community organizations to define their current data uses and needs. Survey and literature review findings informed a one-day deliberative dialogue event with 19 participants who brought multiple perspectives together on the barriers and potential solutions for data sharing. RESULTS: Results are discussed utilizing the three stages of data sharing: awareness, communication, and collaboration. Awareness of the barriers and needs of community partners related to data, and the public health core competency of assessment and analysis is the first stage. More effective is the second stage, where LPHAs proactively communicate to understand and meet the needs of community partners. Data sharing is the most effective when LPHAs use the third stage of collaboration to work with community partners to mutually benefit from data sharing. CONCLUSION: When LPHAs utilize their core competencies of assessment and analysis, communication, and collaboration to share data with community partners, they are able to share data more effectively. This allows community partners to modify programs to better serve priority populations and improve population health.

Bariatric Surgery in the Elderly Is Associated with Similar Surgical Risks and Significant Long-Term Health Benefits.

PURPOSE: Older age (> 60) has been considered a relative contraindication for bariatric surgery due to increased complication risk. This study examined the risks and benefits of bariatric surgery for patients older than 60 years in Canadian population. METHODS: This was a retrospective cohort study of the Ontario Bariatric Registry: a database recording peri-operative and post-operative outcomes of publicly funded bariatric surgeries across the province. Patients who completed 1 year follow-up, who underwent laparoscopic gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) between January 2010 and May 2013, were divided into older (> 60) and younger (> 60) cohorts, and outcomes were compared. RESULTS: Between January 2010 and May 2013, 3166 registry patients underwent LRYGB or LSG and completed 1-year follow-up. Of these, 204 (6.5%) were older than 60 years, with 175 (85.8%) undergoing LRYGB and 29 (14.2%) LSG. Demographics were similar, except for a higher number of males in the older group (59 (28.9%) versus 452 (15.3%) (p < 0.001)). No significant difference in complication rate was noted (15% for younger cohort versus 13.8% (p = 0.889)). The average percentage of excess weight loss was significantly higher in the younger population (60.72% versus 56.25% (p < 0.05)) overall, however not significantly in the LSG group. Reduction in medication use post-surgery for management of co-morbidities was significantly higher in the older patients (- 0.91 versus - 2.03 (p < 0.001)). CONCLUSION: The older cohort who underwent LRYGB or LSG was at no greater risk for intra-operative and post-operative complications and showed greater reduction in medication use post-surgery when compared to the younger cohort.

Impact of research investment on scientific productivity of junior researchers.

There is a demand for providing evidence on the effectiveness of research investments on the promotion of novice researchers' scientific productivity and production of research with new initiatives and innovations. We used a mixed method approach to evaluate the funding effect of the New Investigator Fund (NIF) by comparing scientific productivity between award recipients and non-recipients. We reviewed NIF grant applications submitted from 2004 to 2013. Scientific productivity was assessed by confirming the publication of the NIF-submitted application. Online databases were searched, independently and in duplicate, to locate the publications. Applicants' perceptions and experiences were collected through a short survey and categorized into specified themes. Multivariable logistic regression was performed. Odds ratios (OR) with 95 % confidence intervals (CI) are reported. Of 296 applicants, 163 (55 %) were awarded. Gender, affiliation, and field of expertise did not affect funding decisions. More physicians with graduate education (32.0 %) and applicants with a doctorate degree (21.5 %) were awarded than applicants without postgraduate education (9.8 %). Basic science research (28.8 %), randomized controlled trials (24.5 %), and feasibility/pilot trials (13.3 %) were awarded more than observational designs (p < 0.001). Adjusting for applicants and application factors, awardees published the NIF application threefold more than non-awardees (OR = 3.4, 95 %, CI = 1.9, 5.9). The survey response rate was 90.5 %, and only 58 % commented on their perceptions, successes, and challenges of the submission process. These findings suggest that research investments as small as seed funding are effective for scientific productivity and professional growth of novice investigators and production of research with new initiatives and innovations. Further efforts are recommended to enhance the support of small grant funding programs.

Comprehensive Clinical Staging for Resectable Lung Cancer: Clinicopathological Correlations and the Role of Brain MRI.

INTRODUCTION: In our model of comprehensive clinical staging (CCS) for lung cancer, patients with a computerized tomography scan of the chest and upper abdomen not showing distant metastases will then routinely undergo whole body positron emission tomography/computerized tomography and magnetic resonance imaging (MRI) of the brain before any therapeutic decision. Our aim was to determine the accuracy of CCS and the value of brain MRI in this population. METHODS: A retrospective analysis of a prospectively entered database was performed for all patients who underwent lung cancer resection from January 2012 to June 2014. Demographics, clinical and pathological stage (seventh edition of the American Joint Committee on Cancer/Union for International Cancer Control tumor, node, and metastasis staging manual), and costs of staging were collected. Correlation between clinical and pathological stage was determined. RESULTS: Of 315 patients with primary lung cancer, 55.6% were female and the mean age was 70 ± 9.6 years. When correlation was analyzed without consideration for substages A and B, 49.8% of patients (158 of 315) were staged accurately, 39.7% (125 of 315) were overstaged, and 10.5% (32 of 315) were understaged. Only 4.7% of patients (15 of 315) underwent surgery without appropriate neoadjuvant treatment. Preoperative brain MRI detected asymptomatic metastases in four of 315 patients (1.3%). At a median postoperative follow-up of 19 months (range 6-43), symptomatic brain metastases developed in seven additional patients. The total cost of CCS in Canadian dollars was $367,292 over the study period, with $117,272 (31.9%) going toward brain MRI. CONCLUSION: CCS is effective for patients with resectable lung cancer, with less than 5% of patients being denied appropriate systemic treatment before surgery. Brain MRI is a low-yield and high-cost intervention in this population, and its routine use should be questioned.

Diagnostic accuracy of physical examination for anterior knee instability: a systematic review.

PURPOSE: Determining diagnostic accuracy of Lachman, pivot shift and anterior drawer tests versus gold standard diagnosis (magnetic resonance imaging or arthroscopy) for anterior cruciate ligament (ACL) insufficiency cases. Secondarily, evaluating effects of: chronicity, partial rupture, awake versus anaesthetized evaluation. METHODS: Searching MEDLINE, EMBASE and PubMed identified studies on diagnostic accuracy for ACL insufficiency. Studies identification and data extraction were performed in duplicate. Quality assessment used QUADAS tool, and statistical analyses were completed for pooled sensitivity and specificity. RESULTS: Eight studies were included. Given insufficient data, pooled analysis was only possible for sensitivity on Lachman and pivot shift test. During awake evaluation, sensitivity for the Lachman test was 89 % (95 % CI 0.76, 0.98) for all rupture types, 96 % (95 % CI 0.90, 1.00) for complete ruptures and 68 % (95 % CI 0.25, 0.98) for partial ruptures. For pivot shift in awake evaluation, results were 79 % (95 % CI 0.63, 0.91) for all rupture types, 86 % (95 % CI 0.68, 0.99) for complete ruptures and 67 % (95 % CI 0.47, 0.83) for partial ruptures. CONCLUSION: Decreased sensitivity of Lachman and pivot shift tests for partial rupture cases and for awake patients raised suspicions regarding the accuracy of these tests for diagnosis of ACL insufficiency. This may lead to further research aiming to improve the understanding of the true accuracy of these physical diagnostic tests and increase the reliability of clinical investigation for this pathology.
