Abstract Extreme longevity is associated with resilience to Alzheimer’s disease. A major goal of centenarian studies is therefore to identify factors associated with maintaining cognitive function throughout life. Over the past year, two studies of centenarians and their offspring (age 60-110+ years) have pivoted from in-home assessments of cognitive and physical function to hybridized, Zoom-based assessments including comprehensive cognitive testing, blood pressure, grip strength, and accelerometry and biological sample collections. Protocols were optimized for accessibility for individuals with limited technology experience (e.g., investigator remotely controls all functions of the participant’s tablet) and sensory impairments (e.g., integration of wireless headphones) and include high-sensitivity data collection (e.g., sensor-based wearables and digital recording of cognitive test responses). Advantages of virtual administration included the ability to accommodate fatigue through multi-day assessment and to include geographically-isolated individuals. Disadvantages included participant burden due to equipment setup and inability to collect certain measures virtually (e.g., carotid ultrasounds).

SETTING: This survey was conducted at 35 sites of 20 cities in 15 districts with low programmatic TB case notifications in the past years in Balochistan.OBJECTIVE: To assess the effectiveness of the systemic community-based screening and diagnosis for early detection of TB; and 2) to describe the characteristics and understand the strengths and weaknesses of the intervention in Balochistan, and sociodemographic factors associated with it.DESIGN: This cross-sectional descriptive study was conducted using a mobile van equipped with a digital X-ray machine with computer-aided detection for TB (CAD4TB) software for screening, followed by confirmatory high sensitivity Xpert® MTB/RIF assay testing.RESULTS: A total of 236 (3.4%) TB cases was detected out of 6,899 screened. About 1,168 (17%) presumptive TB cases were identified and 1,065 (91%) sputum samples were tested on Xpert. Among those diagnosed, 166 (70%) were Mycobacterium tuberculosis-positive and 70 (30%) were with clinical suspicion. Of the sputum samples tested, 87% (923/1065) had a probability score of >70 on CAD4TB.CONCLUSION: Community-based screening with innovative activities, comprising sensitive screening and diagnostic tools, effectively improves TB case detection, which might suffice to reduce the prevalence of TB and break the chain of infection transmission in the at-risk population.

AbstractObjectivesThe study aimed to examine factors associated with past 30 days waterpipe use among high school students in Jakarta, Indonesia.MethodsWe surveyed a multistage cluster random sample of 1,318 students of grade 10th and 11th from 14 schools in Jakarta. Multiple logistic regressions were employed to examine the association between past 30 days waterpipe use with sociodemographic characteristics, cigarettes smoking status, parental and peer use, availability and affordability.ResultsOf 1,318 participants, 3.3% of female and 8.4% of male currently smoked waterpipe. Multivariate analysis revealed that current waterpipe use was significantly associated with family use (AOR: 4.844, 95% CI: 1.225–19.151), friend use (AOR: 2.554, 95% CI: 1.424–4.582), and availability (AOR: 2.143, 95% CI: 1.127–4.076). Being current smokers were six times more likely (AOR: 6.055, 95% CI: 3.123–11.739) to use waterpipe in the past 30 days.ConclusionsThe finding suggests that smoking by a family member, friends, use of conventional cigarettes, and availability are significantly associated with increased probability of current waterpipe used among adolescents.

Abstract Objective The goals of this study were to assess the ability of salivary non-coding RNA (ncRNA) levels to predict post-concussion symptoms lasting ≥ 21 days, and to examine the ability of ncRNAs to identify recovery compared to cognition and balance. Methods RNA sequencing was performed on 505 saliva samples obtained longitudinally from 112 individuals (8–24-years-old) with mild traumatic brain injury (mTBI). Initial samples were obtained ≤ 14 days post-injury, and follow-up samples were obtained ≥ 21 days post-injury. Computerized balance and cognitive test performance were assessed at initial and follow-up time-points. Machine learning was used to define: (1) a model employing initial ncRNA levels to predict persistent post-concussion symptoms (PPCS) ≥ 21 days post-injury; and (2) a model employing follow-up ncRNA levels to identify symptom recovery. Performance of the models was compared against a validated clinical prediction rule, and balance/cognitive test performance, respectively. Results An algorithm using age and 16 ncRNAs predicted PPCS with greater accuracy than the validated clinical tool and demonstrated additive combined utility (area under the curve (AUC) 0.86; 95% CI 0.84–0.88). Initial balance and cognitive test performance did not differ between PPCS and non-PPCS groups (p > 0.05). Follow-up balance and cognitive test performance identified symptom recovery with similar accuracy to a model using 11 ncRNAs and age. A combined model (ncRNAs, balance, cognition) most accurately identified recovery (AUC 0.86; 95% CI 0.83–0.89). Conclusions ncRNA biomarkers show promise for tracking recovery from mTBI, and for predicting who will have prolonged symptoms. They could provide accurate expectations for recovery, stratify need for intervention, and guide safe return-to-activities.

Abstract Background In March 2020, the World Health Organization (WHO) declared COVID-19 a pandemic. Many countries in Sub-Saharan Africa, Uganda inclusive, implemented lockdowns, curfew, banning of both private and public transport systems, and mass gatherings to minimize spread. Social control measures for COVID-19 are reported to increase violence and discrimination globally, including in Uganda as some may be difficult to implement resulting in the heavy deployment of law enforcement. Media reports indicated that cases of violence and discrimination had increased in Uganda’s communities following the lockdown. We estimated the incidence and factors associated with experiencing violence and discrimination among Ugandans during the COVID-19 lockdown to inform control and prevention measures. Methods In April 2020, we conducted a secondary analysis of cross-sectional data under the International Citizen Project (ICP) to assess adherence to public health measures and their impact on the COVID-19 outbreak in Uganda. We analyzed data on violence and discrimination from the ICP study. We performed descriptive statistics for all the participants’ characteristics and created a binary outcome variable called experiencing violence and/or discrimination. We performed logistic regression analysis to identify the factors associated with experiencing violence and discrimination. Results Of the 1726 ICP study participants, 1051 (58.8%) were males, 841 (48.7%) were currently living with a spouse or partner, and 376 (21.8%) had physically attended work for more than 3 days in the past week. Overall, 145 (8.4%) experienced any form of violence and/or discrimination by any perpetrator, and 46 (31.7%) of the 145 reported that it was perpetrated by a law enforcement officer. Factors associated with experiencing violence or discrimination were: being male (AOR = 1.60 CI:1.10–2.33), having attended work physically for more than 3 days in the past week (AOR = 1.52 CI:1.03–2.23), and inability to access social or essential health services since the epidemic started (AOR = 3.10 CI:2.14–4.50). Conclusion A substantial proportion of Ugandan residents experienced violence and/or discrimination during the COVID-19 lockdown, mostly perpetrated by law enforcement officers. We recommend mitigation of the collateral impact of lockdowns with interventions that focus on improving policing quality, ensuring continuity of essential services, and strengthening support systems for vulnerable groups including males.

Abstract Sepsis in the United States has an estimated annual healthcare cost of $16.7 billion and leads to 120 000 deaths. Insufficient development in both medical diagnosis and treatment of sepsis has led to continued growth in reported cases of sepsis over the past two decades with little improvement in mortality statistics. Efforts over the last decade to improve diagnosis have unsuccessfully sought to identify a “magic bullet” proteic biomarker that provides high sensitivity and specificity for infectious inflammation. More recently, genetic methods have made tracking regulation of the genes responsible for these biomarkers possible, giving current research new direction in the search to understand how host immune response combats infection. Despite the breadth of research, inadequate treatment as a result of delayed diagnosis continues to affect approximately one fourth of septic patients. In this report we review past and present diagnostic methods for sepsis and their respective limitations, and discuss the requirements for more timely diagnosis as the next step in curtailing sepsis-related mortality. We also present a proposal toward revision of the current diagnostic paradigm to include real-time immune monitoring.

Developmental Dyscalculia (DD) is a specific learning disability of childhood, which is mainly related to problems in arithmetic skills and numerosity. It is estimated that the prevalence of dyscalculia range between 3 and 6 % of the world population. DD is a cognitive disorder, observed during the development of the individual. Mathematical achievement of children with DD fall far short of their mental capacity. In this study we present an approach to genetic, neurological and environmental factors associated with DD, as well as the computerized screening tools that have been developed and used so far, according to the literature review of the past two decades.

During the past decade, there has been increasing pressure on correctional agencies to attract and keep quality staff. Raising worker job satisfaction is seen as a fundamental way of decreasing turnover. There has been a considerable amount of research in the area of the possible causes of correctional staff job satisfaction and, to a lesser extent, the possible consequences of job satisfaction. However, due to the numerous studies, some with conflicting results, it is difficult to understand clearly the factors associated with job satisfaction. A review of the literature is presented to provide a better understanding of correctional staff job satisfaction. Based on this review, correctional administrators are urged to concentrate more on improving the work environment rather than focusing on correctional staff characteristics.

Context:  Meta-analyses examining construct-specific cognitive impairment concurrently with self-reported symptoms postconcussion are sparse. Objective:  To review the literature on the effects of concussion on construct-specific neurocognitive declines and to compare them with self-reported symptoms before 1 week and between 1 and 3 weeks postconcussion. Data Sources:  Relevant studies in PubMed, CINAHL, and PsycINFO published from January 1, 1999 through November 30, 2015. Study Selection:  Studies were included if participants completed the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) before and after concussion and if test performance and Postconcussion Symptom Scale (PCSS) scores were reported at both times. Data Extraction:  After reviewing the full texts, we extracted data from 17 studies consisting of 29 independent samples; therefore, this meta-analysis consisted of 1777 unique participants. Data Synthesis:  The Hedges g effect size (ES) was estimated. A random-effects or fixed-effects model was used based on heterogeneity findings. When heterogeneity was present, we used meta-regression to assess unexplained between-studies variance. Within the first week of injury, the ESs were small to moderate for cognitive declines, ranging from −0.43 (95% confidence interval [CI] = −0.52, −0.35) to −0.67 (95% CI = −0.77, −0.58), and large for the PCSS score (Hedges g = −0.81; 95% CI = −0.91, −0.71). After 1 week, the ESs for cognitive declines (Hedges g range = −0.25 [95% CI = −0.35, −0.15] to −0.37 [95% CI = −0.55, −0.19]) and PCSS score (Hedges g = −0.38; 95% CI = −0.53, −0.22) were also small. Within 2 weeks of injury, PCSS score and time since injury weakly moderated the cognitive ES. Conclusions:  When a neurocognitive test was administered within 1 week of injury, the ES was larger for self-reported symptoms than for ImPACT scores generated at the same session. After 1 week of injury, the ESs for ImPACT and PCSS scores were comparable. If the athlete reports symptoms within 1 week of injury, administering a cognitive test does not appear to offer additional information to the clinician. However, if the athlete does not report symptoms postconcussion, cognitive testing may inform the clinical management of the injury.

Computerised cognitive assessments are a vital tool in the behavioural sciences, but participants often view them as effortful and unengaging. One potential solution is to add gamelike elements to these tasks in order to make them more intrinsically enjoyable, and some researchers have posited that a more engaging task might produce higher quality data. This assumption, however, remains largely untested. We investigated the effects of gamelike features and test location on the data and enjoyment ratings from a simple cognitive task. We tested three gamified variants of the Go-No-Go task, delivered both in the laboratory and online. In the first version of the task participants were rewarded with points for performing optimally. The second version of the task was framed as a cowboy shootout. The third version was a standard Go-No-Go task, used as a control condition. We compared reaction time, accuracy and subjective measures of enjoyment and engagement between task variants and study location. We found points to be a highly suitable game mechanic for gamified cognitive testing because they did not disrupt the validity of the data collected but increased participant enjoyment. However, we found no evidence that gamelike features could increase engagement to the point where participant performance improved. We also found that while participants enjoyed the cowboy themed task, the difficulty of categorising the gamelike stimuli adversely affected participant performance, increasing No-Go error rates by 28% compared to the non-game control. Responses collected online vs. in the laboratory had slightly longer reaction times but were otherwise very similar, supporting other findings that online crowdsourcing is an acceptable method of data collection for this type of research.

Abstract Background: The World Health Organization (WHO) recommends the use of pre-exposure prophylaxis (PrEP) in key populations at elevated risk for exposure to HIV. If used effectively, PrEP can reduce annual HIV incidence to below 0.05%. However, PrEP is not acceptable among all communities that might benefit from it. There is, therefore, a need to understand perceptions of PrEP and factors associated with willingness to use PrEP among key populations at risk of HIV, such as members of communities with exceptionally high HIV prevalence. Objective: To examine the perceptions and factors associated with willingness to use oral PrEP among members of fishing communities in Uganda, a key population at risk of HIV. Methods: We conducted an explanatory sequential mixed-methods study at Ggaba fishing community from February to June 2019. Survey data were collected from a systematic random sample of 283 community members. We carried out bivariate tests of association of willingness to use PrEP with demographic characteristics, HIV risk perception, HIV testing history. We estimated prevalence ratios for willingness to use PrEP. We used backward elimination to build a multivariable modified Poisson regression model to describe factors associated with willingness to use PrEP. We purposively selected 16 participants for focus group discussions to contextualize survey findings, analysing data inductively and identifying emergent themes related to perceptions of PrEP. Key results: We enrolled 283 participants with a mean age of 31±8 years. Most (80.9%) were male. The majority of participants had tested for HIV in their lifetime, but 64% had not tested in the past 6 months. Self-reported HIV prevalence was 6.4%. Most (80.6%, 95%CI 75.5-85.0) were willing in principle to use PrEP. Willingness to use PrEP was associated with perceiving oneself to be at high risk of HIV (aPR 1.99, 95%CI 1.31-3.02, P= 0.001), having tested for HIV in the past 6-months (aPR 1.13, 95%CI 1.03-1.24, P=0.007), and completion of tertiary education (aPR 1.97, 95%CI 1.39-2.81, P<0.001). In focus group discussions, participants described pill burden, side-effects, drug safety, and accessibility as potential barriers to PrEP use. Conclusions and recommendations: Oral PrEP was widely acceptable among members of fishing communities in peri-urban Kampala. Programs for scaling-up PrEP for fisherfolk should merge HIV testing services with sensitization about PrEP and also address issues of access to drugs.
