OBJECTIVE/UNASSIGNED:Workplace-based employee health promotion programs often target weight loss or physical activity, yet there is growing attention to sleep as it affects employee health and performance. The goal of this review is to systematically examine workplace-based employee health interventions that measure sleep duration as an outcome. DATA SOURCE/UNASSIGNED:We conducted systematic searches in PubMed, Web of Knowledge, EMBASE, Scopus, and PsycINFO (n = 6177 records). STUDY INCLUSION AND EXCLUSION CRITERIA/UNASSIGNED:To be included in this systematic review, studies must include (1) individuals aged >18 years, (2) a worker health-related intervention, (3) an employee population, and (4) sleep duration as a primary or secondary outcome. RESULTS/UNASSIGNED:Twenty studies met criteria. Mean health promotion program duration was 2.0 months (standard deviation [SD] = 1.3), and mean follow-up was 5.6 months (SD = 6.5). The mean sample size of 395 employees (SD = 700.8) had a mean age of 41.5 years (SD = 5.2). Measures of sleep duration included self-report from a general questionnaire (n = 12, 66.6%), self-report based on Pittsburgh Sleep Quality Index (n = 4, 22.2%), and self-report and actigraphy combined (n = 5, 27.7%). Studies most commonly included sleep hygiene (35.0%), yoga (25.0%), physical activity (10.0%), and cognitive-behavioral therapy for insomnia (10.0%) interventions. Across the interventions, 9 different behavior change techniques (BCTs) were utilized; the majority of interventions used 3 or fewer BCTs, while 1 intervention utilized 4 BCTs. Study quality, on average, was 68.9% (SD = 11.1). Half of the studies found workplace-based health promotion program exposure was associated with a desired increase in mean nightly sleep duration (n = 10, 50.0%). CONCLUSIONS/UNASSIGNED:Our study findings suggest health promotion programs may be helpful for increasing employee sleep duration and subsequent daytime performance.

Purpose of review/UNASSIGNED:To systematically review the available research studies that characterize the benefits, uncertainty, or weaknesses of commercially-available sleep tracking technology. Recent findings/UNASSIGNED:Sleep is a vital component of health and well-being. Research shows that tracking sleep using commercially available sleep tracking technology (e.g., wearable or smartphone-based) is increasingly popular in the general population. Methods/UNASSIGNED:Systematic literature searches were conducted using PubMed/Medline, Embase (Ovid) the Cochrane Library, PsycINFO (Ovid), CINAHL, and Web of Science Plus (which included results from Biosis Citation Index, INSPEC, and Food, Science & Technology Abstracts) (n=842). Study Inclusion and Exclusion Criteria/UNASSIGNED:Three independent reviewers reviewed eligible articles that administered a commercially-available sleep tracker to participants and reported on sleep parameters as captured by the tracker, including either sleep duration or quality. Eligible articles had to include sleep data from users for >=4 nights.

BACKGROUND:Integrated cardiovascular disease (CVD) and HIV (CVD-HIV) care interventions are being adopted to tackle the growing burden of noncommunicable diseases (NCDs) in low-and middle-income countries (LMICs) but there is a paucity of studies on the feasibility of these interventions in LMICs. This scoping review aims to present evidence of the feasibility of integrated CVD-HIV care in LMICs, and the alignment of feasibility reporting in LMICs with the existing implementation science methodology. METHODS:A systematic search of published articles including systematic and narrative reviews that reported on integrated CVD-HIV care was conducted, using multiple search engines including PubMed/Medline, Global Health, and Web of Science. We examined the articles for evidence of feasibility reporting. Adopting the definition of Proctor and colleagues (2011), feasibility was defined as the extent to which an intervention was plausible in a given agency or setting. Evidence from the articles was synthesized by level of integration, the chronic care continuum, and stages of intervention development. RESULTS:Twenty studies, reported in 18 articles and 3 conferences abstracts, reported on feasibility of integrated CVD-HIV care interventions. These studies were conducted in Sub-Saharan Africa, Southeast Asia and South America. Four of these studies were conducted as feasibility studies. Eighty percent of the studies reported feasibility, using descriptive sentences that included words synonymous with feasibility terminologies in existing definition recommended by Proctor and colleagues. There was also an overlap in the use of descriptive phrases for feasibility amongst the selected studies. CONCLUSIONS:Integrating CVD and HIV care is feasible in LMICs, although methodology for reporting feasibility is inconsistent. Assessing feasibility based on settings and integration goals will provide a unique perspective of the implementation landscape in LMICs. There is a need for consistency in measures in order to accurately assess the feasibility of integrated CVD-HIV care in LMICs.

Guillain-Barre syndrome (GBS), a severe autoimmune disorder, is the most common cause of acute flaccid paralysis. Between 20%-30% of patients require mechanical ventilation. Mortality rates range from 3%-7% and are higher in low-resource settings. The median global incidence of GBS is estimated at 1.1/100,000 (range 0.8-1.9). However, this is based on studies from Europe and North America. Many countries reported increases in GBS cases following the 2015-2016 Zika epidemic. Recent data from Latin America and the Caribbean (LAC) present an opportunity to assess the GBS incidence in the region for the first time. We conducted a systematic review of the incidence of GBS and searched 9 scientific databases from 1980-2017 using pre-defined search-terms. We included publications reporting primary GBS incident cases within well-defined populations. A detailed protocol is available at PROSPERO (CRD42018086659). Of 6568 identified publications, we screened 4093 titles/abstracts after removing duplicates; of 118 full-text articles reviewed, 24 met inclusion criteria. The majority (62.5%, n=15) was published after 2015. While 3 were multi-country studies; 7 were from Caribbean, including Puerto Rico; 7 from Brazil; 5 from other South American countries; and 2 from Central America and Mexico. Six analyzed the incidence of GBS in children and 2 in adults only. Sources of data included national surveillance systems (GBS disease became notifiable in 2016), hospitalization records, and the Polio Eradication Surveillance System. Background rates of GBS varied from 0.3 per 100,000 persons in Natal, Brazil to 2.65 in El Salvador and 1.31 in Honduras. GBS incidence rates increased 2 to 9.8 times from baseline during the Zika epidemic. Trends were inconclusive for chikungunya and dengue. This is the first review summarizing the GBS incidence in LAC. Central American countries appear to have higher background incidence rates of GBS than the Southern Cone and the Caribbean. GBS incidence seems to increase during arboviral epidemics, particularly Zika. GBS poses an additional burden to healthcare systems, particularly in low-resource settings.

Minority individuals in the United States (US) have an increased prevalence of obstructive sleep apnea (OSA) compared to their white/Caucasian counterparts. In general, adherence to positive airway pressure (PAP) therapy is poor and some studies suggest that PAP use among minority individuals is inferior to that of whites. However, there has not been a review of the evidence that addresses racial-ethnic disparities for PAP adherence in the treatment of OSA, and no review has systematically examined the contributing factors to poor adherence among minority individuals compared to whites. We searched the literature for studies published between January 1990 to July 2016 that included objective PAP use comparisons between adult US minority individuals and whites. Twenty-two studies met the inclusion criteria. All studies compared the PAP adherence of blacks to whites. Seven studies compared the PAP adherence of additional minority groups to that of whites. Sixteen of the 22 studies (73%) showed worse PAP adherence in blacks compared to whites. Four studies found equivalent PAP use in US Hispanics compared to whites. Little is known about the PAP adherence of other US minority groups. We present a framework and research agenda for understanding PAP use barriers among US minority individuals.

Importance/UNASSIGNED:Human papillomavirus (HPV) vaccination is recommended for children and younger adults but not older adults or those with prior HPV exposure, leaving a large portion of the population at risk for HPV-mediated disease. Emerging data suggest a possible role for vaccination as an adjuvant treatment for individuals with HPV-related clinical disease. Objective/UNASSIGNED:To systematically review the literature regarding HPV vaccination for secondary disease prevention after treatment of active clinical disease across disease sites to serve as a platform for the management of HPV-related disease of the head and neck. Evidence Review/UNASSIGNED:A systematic search from August 3 to 21, 2015, of the PubMed, MEDLINE, EMBASE, CINAHL, Cochrane Library, Web of Science, Biosis Citation Index, Current Contents Connect, Scientific Library Online, and Global Health databases used PRISMA guidelines to identify 326 relevant articles related to adjuvant use of HPV vaccination. Primary search terms were (HPV vaccine OR human papillomavirus vaccine OR papillomarvirus vaccines OR alphapapillomavirus vaccine) AND (HPV OR human papillomavirus OR alphapapillomavirus OR papillomaviridae OR virus warts OR wart virus) AND (recurrence OR relapse OR reoccurrence OR recurrences OR relapses OR relapsing). Forty-five full texts in English were reviewed, with 19 articles included in the final review. In some studies, subpopulations of individuals with HPV DNA positivity and/or seropositivity were extracted for inclusion. Included studies were assessed for bias and separated based on the presence of active clinical disease or HPV DNA positivity or seropositivity. Findings/UNASSIGNED:Nineteen studies with 22 474 unique patients were included in the review. When HPV vaccination was used as an adjuvant treatment for active clinical disease, 9 of 12 studies reported decreased disease recurrence, decreased disease burden, or increased intersurgical interval. In contrast, none of the 7 studies of vaccination in individuals with HPV DNA positivity and/or seropositivity without clinical disease reported improved outcomes. Conclusions and Relevance/UNASSIGNED:Differences between adjuvant vaccination in HPV-mediated clinical disease and vaccination in HPV DNA-positive and/or HPV-seropositive populations posit underlying differences in disease and immune processes. These data suggest that additional evaluation of adjuvant HPV vaccination in individuals with active clinical disease is warranted.

Objective/UNASSIGNED:Obstructive sleep apnea (OSA) is a common sleep-disordered breathing condition that has emerged as a significant public health problem given its increased prevalence over the past decade. The high prevalence of obesity and large waist circumference among NFL players are two risk factors that might contribute to the high susceptibility of football players to develop OSA. National Football League linemen might be particularly vulnerable since they tend to have a higher body mass index. In this scoping review, we aim to bring attention to the limited research regarding OSA among National Football League players and highlight the negative consequences of OSA in an attempt to increase awareness of the urgent need for further research in this area. Methods/UNASSIGNED:Search terms associated with obstructive sleep apnea and football were used to examine Google Scholar, EMBASE, CINAHL, PubMed, ProQuest, and Web of Science Plus for relevant studies. All relevant studies were included and documented. Results/UNASSIGNED:Findings included (n=4) studies of interest. All 4 studies revealed a near or slightly above 50% prevalence of OSA in the investigated cohorts (mostly retired NFL linemen). Most participants in the study (active NFL players) showed symptoms associated with a sleep-disorder breathing condition (snoring). Conclusion/UNASSIGNED:OSA requires more attention from the research and medical community. As suggested by results in the 4 studies included in this paper, OSA and associated symptoms are prevalent in the NFL population. Further research is required to investigate the extent of OSA and OSA risk in this population. There is an urgent need to conduct OSA risk surveillance in the athletic community.

In addition to physical health challenges, older people living with HIV/AIDS (PLWHA) experience mental health burdens and challenges to their social well-being that diminish their overall health. These health states are synergistic and are driven by HIV and HIV treatments, the aging process itself, and psychosocial and structural conditions of their lives. However, resilience, which we understand as both a trait and a process, may serve to buffer the effects that HIV/HIV treatments, aging, and social/structural conditions may have on the overall well-being of the individual. In this chapter, we examine the extant literate on the mental health and psychosocial challenges experienced by older PLWHA as elements of the total health of the individual. We also provide a contextualization and conceptualization for understanding the significant role that resilience may play in empowering individuals to enact processes which buffer health from the stressors. In this perspective, the health of older PLWHA must be viewed through a lens of power and strength rather than one of deficit. We conclude by outlining a theoretical paradigm for the role of resilience in the health of older HIV-positive adults, which may serve as a guide to clinicians, public health practitioners, and researchers working with this population.

BACKGROUND: There is debate regarding preoperative endoscopy (EGD) in patients undergoing bariatric surgery. Some centers perform EGD routinely in all patients; others perform EGD selectively. The objective of this study was to perform a systematic review and meta-analysis of the existing literature to estimate how frequently preoperative EGD changes management. METHODS: Our review yielded 28 studies encompassing 6616 patients. Baseline characteristics including age and body mass index (BMI) were included. Patients were grouped based on EGD findings into two groups: Group 1-findings which did not significantly change management (e.g., mild/moderate duodenitis, Grade A/B esophagitis, mild/moderate gastritis, H. pylori infection, hiatal hernia <2 cm); Group 2-findings which delayed, altered, or cancelled surgery (e.g., severe duodenitis, Grade C/D esophagitis, gastric varices, hiatal hernia >2 cm, mass/carcinoma). A general estimating equation (GEE) model accounting for the correlated data within each study was used to calculate confidence intervals around the estimate of how frequently surgery was delayed or altered. RESULTS: Mean age was 41.4 +/- 2.9 years, the majority was women, and mean preoperative BMI was 47 +/- 3.2 kg/m2. Overall 92.4 % (n = 6112) had a normal EGD or findings that did not change clinical management and 7.6 % (n = 504); 95 % CI [4.6, 12.4 %] had findings that delayed/altered surgery. The revised estimate was 20.6 %; 95%CI [14.5, 28.2 %] if all esophagitis (regardless of grade) were categorized into Group 2. The approximate incidence of Barrett's esophagus and carcinoma were 0.1 and 0.08 %, respectively. CONCLUSION: A selective approach to preoperative EGD may be considered, based on the patients' symptoms, risk factors, and type of procedure planned.

This review is an update to the American College of Gastroenterology (ACG) Committee on Minority Affairs and Cultural Diversity's paper on colorectal cancer (CRC) in African Americans published in 2005. Over the past 10 years, the incidence and mortality rates of CRC in the United States has steadily declined. However, reductions have been strikingly much slower among African Americans who continue to have the highest rate of mortality and lowest survival when compared with all other racial groups. The reasons for the health disparities are multifactorial and encompass physician and patient barriers. Patient factors that contribute to disparities include poor knowledge of benefits of CRC screening, limited access to health care, insurance status along with fear and anxiety. Physician factors include lack of knowledge of screening guidelines along with disparate recommendations for screening. Earlier screening has been recommended as an effective strategy to decrease observed disparities; currently the ACG and American Society of Gastrointestinal Endoscopists recommend CRC screening in African Americans to begin at age 45. Despite the decline in CRC deaths in all racial and ethnic groups, there still exists a significant burden of CRC in African Americans, thus other strategies including educational outreach for health care providers and patients and the utilization of patient navigation systems emphasizing the importance of screening are necessary. These strategies have been piloted in both local communities and Statewide resulting in notable significant decreases in observed disparities.
