RESUMO
A study was developed for a limb-different accessible video game controller that utilizes an electromyographic sensor to control gameplay actions. Data was collected from 50 college-aged student participants. This biofeedback-based serious game trains users in a virtual capacity, through the visualization of muscle contraction, via the movement of the video game character. The training platform has been developed to accompany the corresponding electromyographic actuated prosthetic arm device, leveraging the same control scheme to enable the translation of hand gesture states. This study evaluated the controller, user interface, and gameplay to identify training improvement outcomes and user satisfaction. Study participants were divided into two cohorts that differed in their intervention between the pre-test and post-test challenge course. Cohort one had a free play environment that encouraged learning through algorithmically generated track patterns and the use of powerups. In contrast, cohort two repeated the challenge mode, which was made up of a course of rings to jump through and focused on targeted muscle discretization via character jump heights correlated to muscle output. Data were collected to develop and validate training methods and identify overall game satisfaction and usability. The results of this study indicated an increase in the user's ability to be successful based on time on task with the intervention. The study also evaluated the usability and participant experience with the intervention.

ISSUE ADDRESSED: Philippine contact centres are rife with factors that contribute to work-related stress; health promotion strategies are needed to mitigate the impacts. With a transactional framework with the environment, this study examined the relationship of stress with resilience and the presence of urban green spaces (UGS) in the environment, while accounting for individual characteristics (ie, age, household income, exercise frequency). METHODS: Participants include employees (Stage 1 N = 186; Stage 2 N = 89) from six contact centres in the capital region of the Philippines. A two-stage online survey included standardised instruments to measure stress (10-item Perceived Stress Scale) and resilience (Connor-Davidson Resilience Scale), customised questions to gather demographic information and probe on participants' insights. Google Earth Pro was used for satellite mapping of UGS, followed by on-site ocular inspection. RESULTS: Participants' average stress level was categorised as high; primary stressors included client demands and workload. The objectively measured percentages of UGS in the study sites' vicinity were categorised as low. Participants found UGS visible after careful observation, and majority were aware of UGS in their workplace vicinity. Resilience, household income and awareness of UGS in the vicinity significantly predicted stress levels. CONCLUSION: Contact centre workers experienced high stress levels and their workplaces had little accessible UGS. Resilience, household income and awareness of UGS are significant contributors to stress levels. SO WHAT?: Health promotion in Philippine contact centres could consider strategies that include building resilience, enhancing income security and promoting the awareness of UGS within the workplace vicinity.

In May 2020, Baltimore City, Maryland, implemented the Lord Baltimore Triage, Respite, and Isolation Center (LBTC), a multiagency COVID-19 isolation and quarantine site tailored for people experiencing homelessness. In the first year, 2020 individuals were served, 78% completed isolation at LBTC, and 6% were transferred to a hospital. Successful isolation can mitigate outbreaks in shelters and residential recovery programs, and planning for sustainable isolation services integrated within these settings is critical as the COVID-19 pandemic continues.

Background: Advertising of traditional alcopops contains elements that appeal to youth, especially females. Supersized alcopops are marketed differently than traditional alcopops and contain up to 5.5 standard alcoholic drinks. Young females are more likely to underestimate the alcohol content of supersized alcopops, putting them at higher risk of overconsumption. Similar to supersized alcopops, beer is packaged in large cans and in the same areas of store shelves.Objective: This study examined among young people whether supersized alcopops versus beer products disproportionately appealed to females.Methods: Eleven adolescents (13-17 years old) and 72 college students (21-26 years old) were recruited during 2019-2020. Participants viewed 19 photos of convenience store display cases containing both supersized alcopop and beer products. While viewing each image, participants were instructed to click on the beverage that looked the "coolest" (i.e. most appealing). Eye-tracking hardware and software measured the amount of time participants visually fixated on each product. Participants completed a survey to record demographic characteristics.Results: Compared to males (n=25), females (n=58) fixated on supersized alcopops for 6.8 seconds longer (95%CI 0.3,13.3). Females also had 3.7 times the odds of selecting a supersized alcopop as the product they found most appealing compared to males (95%CI 1.68,8.01), adjusting for amount of time visually fixating on supersized alcopops, which was also a significant predictor.Conclusions: Young females' strong preference for supersized alcopops is concerning given they disproportionately underestimate their potency, relative to males, and are more likely to obtain dangerously high BAC levels from consuming one or two supersized alcopops.

BACKGROUND: Bone marrow stromal cells (BMSCs) have classically been cultured in media supplemented with fetal bovine serum (FBS). As an alternative to FBS, pooled solvent detergent apheresis platelets, HPGF-C18, was evaluated for BMSC culture. METHODS: A comparison of passage 2 BMSC growth revealed that 10% HPGF-C18 produced similar cell numbers as 20% FBS. Marrow aspirates from 5 healthy subjects were cultured for 4 passages in 10% HPGF-C18 or 20% FBS and were analyzed for proliferation, colony formation efficiency (CFE), surface marker expression, suppression of mixed lymphocyte reactions (MLRs), global gene and microRNA expression analysis. BMSC supernatant cytokine and growth factor concentrations were also compared. RESULTS: Primary cultures of marrow aspirates in 10% HPGF-C18 and 20% FBS yielded similar numbers and CFE. After 4 passages, 10% HPGF-C18 and 20% FBS yielded similar numbers of BMSCs, surface marker expression patterns and immunosuppression effects. Gene and microRNA expression analysis revealed that BMSCs cultured under the two conditions had distinct expression profiles. Gene Set Enrichment Analysis (GSEA) revealed HPGF-C18-cultured BMSCs were enriched in metabolic processing and biosynthetic pathways, cell proliferation and cell cycle pathways, and immune response pathways. FBS-cultured BMSCs were enriched in MAPK signaling, TGF-beta signaling, cell adhesion and extracellular matrix pathways. Differently expressed microRNAs were related to the osteogenesis of BMSCs. The supernatant of HPGF-C18 BMSCs had higher levels of PEDF and TGFB1 and lower levels of IL6, VEGF, SDF1 and PLGF. CONCLUSIONS: Traditional measures, expansion, surface marker expression and inhibition of MLRs suggest that BMSC cultured in HPGF-C18 and FBS were similar, but analysis at the molecular level revealed many differences. BMSCs cultured in HPGF-C18 should be assessed in specific functional assays that reflect application-specific potency before substituting FBS with HPGF-C18.

An important negative regulator of factor VIIIa (FVIIIa) cofactor activity is A2 subunit dissociation. FVIII molecules with stabilized activity have been generated by elimination of charged residues at the A1-A2 and A2-A3 interfaces. These molecules exhibited reduced decay rates as part of the enzymatic factor Xa generation complex and retained their activities under thermal and chemical denaturing conditions. We describe here the potency and efficacy of 1 such stability variant, D519V/E665V, derived from B domain-deleted FVIII (BDD-FVIII). The major effect of A2 stabilization was on cofactor activity. D519V/E665V potency was increased twofold by the 2-stage chromogenic assay relative to BDD-FVIII. D519V/E665V demonstrated enhanced thrombin generation responses (fivefold by peak thrombin) relative to BDD-FVIII. In vivo consequences of enhanced cofactor activity of D519V/E665V included >fourfold increased maximal platelet-fibrin deposition after laser injury and twofold increased protection from bleeding in acute and prolonged vascular injury model in hemophilia A mice. These results demonstrate that noncovalent stabilization of the FVIII A2 subunit can prolong its cofactor activity, leading to differential enhancement in clot formation over protection from blood loss in hemophilia. The FVIII molecule described here is the first molecule with clear efficacy enhancement resulting from noncovalent stabilization of the A2 domain.

Numerous responsible gambling (RG) strategies are promoted to assist consumers to "gamble responsibly". However, consumer adoption of RG strategies, how this varies by gambler risk group, and whether usage is associated with non-problematic gambling are largely unknown. This study aimed to (1) determine how use of RG-related strategies differs amongst regular gamblers by gambler risk group; and (2) identify RG-related strategies whose usage predicts non-problem/low risk gambling. Regular Australian gamblers on high-risk products (N = 860), recruited through gambling venues and an online wagering operator, were surveyed about their use of RG strategies promoted on the website of their jurisdiction's main RG agency. Knowledge of RG strategies was reasonably high amongst all gambler risk groups, but lower-risk groups were more likely to use RG strategies. A logistic regression correctly predicted 82.1 % of lower-risk gamblers and 77.2 % of higher-risk gamblers. Predictors of lower-risk gambling included: greater confidence in their understanding of RG; endorsement of lower gambling expenditure and frequency limits; fewer erroneous gambling beliefs; being less likely to gamble to win money, challenge their skills/beat the odds, or forget about worries and stresses; and being more likely to gamble for pleasure/entertainment. Lower-risk gamblers were more likely to set a money limit in advance of gambling and to balance their gambling with other activities. These findings contribute to understanding which strategies are favoured by different risk groups, and which are associated with safer levels of gambling. They can guide consumer information aimed at enhancing RG consumption and future research on RG consumption.

BACKGROUND AIMS: Ex vivo expansion and serial passage of human bone marrow stromal cells (BMSCs, also known as bone marrow-derived mesenchymal stem cells) is required to obtain sufficient quantities for clinical therapy. The BMSC confluence criteria used to determine passage and harvest timing vary widely, and the impact of confluence on BMSC properties remains controversial. The effects of confluence on BMSC properties were studied and confluence-associated markers were identified. METHODS: BMSC characteristics were analyzed as they grew from 50% to 100% confluence, including viability, population doubling time, apoptosis, colony formation, immunosuppression, surface marker expression, global gene expression and microRNA expression. In addition, culture supernatant protein, glucose, lactate and pH levels were analyzed. RESULTS: Confluence-dependent changes were detected in the expression of several cell surface markers: 39 culture supernatant proteins, 26 microRNAs and 2078 genes. Many of these surface markers, proteins, microRNAs and genes have been reported to be important in BMSC function. The pigment epithelium-derived factor/vascular endothelial growth factor ratio increased with confluence, but 80% and 100% confluent BMSCs demonstrated a similar level of immunosuppression of mixed lymphocyte reactions. In addition, changes in lactate and glucose levels correlated with BMSC density. CONCLUSIONS: BMSC characteristics change as confluence increases. 100% confluent BMSCs may have compromised pro-angiogenesis properties but may retain their immunomodulatory properties. Supernatant lactate and glucose levels can be used to estimate confluence and ensure consistency in passage and harvest timing. Flow cytometry or microRNA expression can be used to confirm that the BMSCs have been harvested at the appropriate confluence.

BACKGROUND AND OBJECTIVE: Addressing adverse social determinants of health is an upstream approach to potentially improve child health outcomes and health equity. We aimed to determine if systematically screening and referring for social needs in hospitalized pediatric patients increased families' enrollment in publicly available resources. METHODS: Randomized controlled trial at a large urban children's hospital enrolled English-speaking caregivers of patients 0 to 36 months of age on the general pediatrics service from June 2016 to July 2017. The intervention arm received the WE CARE Houston social needs intervention (screener and resource referrals based on screening results and receptiveness to help); the control arm received standard of care. Baseline social risk data were collected for all participants. Caregivers who screened positive for mental health need, substance abuse, or domestic violence received additional support, including from social workers. The primary outcome was enrollment in resources at 6 months postdischarge. Univariate and multivariable analysis was performed to identify associations. RESULTS: Our study sample consisted of 413 caregivers from diverse sociodemographic/socioeconomic backgrounds. Overall, 85% of study participants had ≥1 social risk (median 2, range 0-9). WE CARE Houston identified caregiver employment, health insurance, primary care physician, depression, childcare, smoking, and food resources as the most prevalent social needs. Among these, caregivers were most receptive to resources for childcare, mental health, health insurance, and primary care. There was no significant difference in enrollment in new resources by study arm. CONCLUSION: Screening for social needs in the hospital is feasible and can result in the identification of social needs, but further work is needed to successfully address these needs.

Colonies of Bacillus anthracis Sterne allow the growth of papillation after 6 days of incubation at 30°C on Luria-Bertani medium. The papillae are due to mutations that allow the cells to overcome the barriers to continued growth. Cells isolated from papillae display two distinct gross phenotypes (group A and group B). We determined that group A mutants have mutations in the nprR gene including frameshifts, deletions, duplications and base substitutions. We used papillation as a tool for finding new mutators as the mutators generate elevated levels of papillation. We discovered that disruption of yycJ or recJ leads to a spontaneous mutator phenotype. We defined the nprR/papillation system as a new mutational analysis system for B. anthracis. The mutational specificity of the new mutator yycJ is similar to that of mismatch repair-deficient strains (MMRâ») such as those with mutations in mutL or mutS. Deficiency in recJ results in a unique specificity, generating only tandem duplications.

BACKGROUND AND OBJECTIVES: Unique ethical, epidemiological, and economic factors are barriers to performing research in children. The landscape of pediatric clinical trials, including drivers of completion and timely dissemination of results, is not well understood. We aimed to characterize the prevalence of and factors associated with early discontinuation, results reporting, and publication of pediatric clinical trials registered at ClinicalTrials.gov. METHODS: Cross-sectional analysis of clinical trials enrolling participants <18 years old registered at ClinicalTrials.gov from October 2007 to March 2020. Multivariable logistic regressions were performed to assess the association between trial characteristics and primary outcomes. Publication data were obtained through PubMed, ClinicalTrials.gov, Embase, and Scopus. RESULTS: Overall, 11.1% trials were stopped early, with recruitment failure being the predominant reason for discontinuation. Only 23.5% of completed trials reported results, and 38.8% were published within 3 years of completion. Rates of discontinuation and publication significantly improved over the study period. Among funding sources, government-sponsored trials (adjusted odds ratio [aOR], 0.72; 95% CI, 0.47-0.97) and academic trials (aOR, 0.64; 95% CI, 0.50-0.82) had lower odds of discontinuation compared with industry trials and were more likely to be published (government: aOR, 1.94 [95% CI, 1.52-2.48] academic: aOR, 1.61 [95% CI, 1.35-1.92). Academic trial investigators were the least likely to report results (aOR, 0.34; 95% CI, 0.31-0.52). CONCLUSIONS: Early discontinuation and nonreporting/nonpublication of findings remain common in registered pediatric clinical trials and were associated with funding source and other trial features. Targeted efforts are needed to support trial completion and timely results dissemination toward strengthening evidence-based pediatric medicine.

Many studies have examined the evolution of bacterial mutants that are resistant to specific antibiotics, and many of these focus on concentrations at and above the MIC. Here we ask for the minimum concentration at which existing resistant mutants can outgrow sensitive wild-type strains in competition experiments at antibiotic levels significantly below the MIC, and we define a minimum selective concentration (MSC) in Escherichia coli for two antibiotics, which is near 1/5 of the MIC for ciprofloxacin and 1/20 of the MIC for tetracycline. Because of the prevalence of resistant mutants already in the human microbiome, allowable levels of antibiotics to which we are exposed should be below the MSC. Since this concentration often corresponds to low or trace levels of antibiotics, it is helpful to have simple tests to detect such trace levels. We describe a simple ultrasensitive test for detecting the presence of antibiotics and genotoxic agents. The test is based on the use of chromogenic proteins as color markers and the use of single and multiple mutants of Escherichia coli that have greatly increased sensitivity to either a wide range of antibiotics or specific antibiotics, antibiotic families, and genotoxic agents. This test can detect ciprofloxacin at 1/75 of the MIC.

OBJECTIVE: Dermatologic complaints are common in outpatient pediatrics. However, pediatric dermatology specialty care can be difficult to access. We aimed to test the feasibility of co-locating dermatology services within primary care and increase the proportion of patients treated for basic skin complaints within the medical home while decreasing wait times. METHODS: The Rapid Assessment of Skin Health (RASH) clinic was created within a hospital-based primary care clinic in 11/2013. The clinic was staffed by 2 pediatricians trained in the dermatology department and supported with specialist advice as needed. Referral volume and wait times to dermatology and RASH clinic were tracked for visits between 11/1/12 and 10/31/18. A chart review was also conducted on a subset of RASH clinic visits. Primary care providers (PCPs) were surveyed about their experiences. RESULTS: Fifty-eight percent of patients referred for a dermatologic complaint were scheduled in RASH clinic. Wait times for new patient appointments in RASH clinic were significantly shorter than for new dermatology appointments in the previous 12 months (mean 36 days vs 65 days, P < .001). The monthly number of referrals to dermatology also decreased significantly after the RASH clinic opened (24/month vs 12/month, P < .001). Ten percent of RASH patients were referred on to dermatology. In a survey of PCPs (N = 67), 76% said the RASH clinic was "extremely/very helpful." CONCLUSIONS: Providing dermatologic care to low or moderate complexity patients within the medical home is feasible and leads to better access to care. This innovative model could be spread to other clinics and subspecialties.

We have defined a sensitivity profile for 22 antibiotics by extending previous work testing the entire KEIO collection of close to 4,000 single-gene knockouts in Escherichia coli for increased susceptibility to 1 of 14 different antibiotics (ciprofloxacin, rifampin [rifampicin], vancomycin, ampicillin, sulfamethoxazole, gentamicin, metronidazole, streptomycin, fusidic acid, tetracycline, chloramphenicol, nitrofurantoin, erythromycin, and triclosan). We screened one or more subinhibitory concentrations of each antibiotic, generating more than 80,000 data points and allowing a reduction of the entire collection to a set of 283 strains that display significantly increased sensitivity to at least one of the antibiotics. We used this reduced set of strains to determine a profile for eight additional antibiotics (spectinomycin, cephradine, aztreonem, colistin, neomycin, enoxacin, tobramycin, and cefoxitin). The profiles for the 22 antibiotics represent a growing catalog of sensitivity fingerprints that can be separated into two components, multidrug-resistant mutants and those mutants that confer relatively specific sensitivity to the antibiotic or type of antibiotic tested. The latter group can be represented by a set of 20 to 60 strains that can be used for the rapid typing of antibiotics by generating a virtual bar code readout of the specific sensitivities. Taken together, these data reveal the complexity of intrinsic resistance and provide additional targets for the design of codrugs (or combinations of drugs) that potentiate existing antibiotics.

The feeding of three co-occurring freshwater mussel species (Ptychobranchus fasciolaris, Quadrula quadrula and Potamilus alatus) of differing conservation status on river water from their collection site was examined under static and ecologically relevant flow conditions using three characteristics of the suspended river seston from a turbid river (Sydenham River, Ontario): (1) Chlorophyll a fluorescence; (2) size of fluorescent particles determined under flow cytometry; and (3) individual algal taxa identified under flow cytometry. Differences in the clearance rate (CR; water volume cleared of material per mussel and time) based on changes in chlorophyll a concentration were observed among species (P. alatusâ¯>â¯Q. quadrula). Mussels had higher CR under flowing conditions and higher CR were observed on four of the nine algal taxa under flowing conditions. Feeding electivity analysis indicated that all mussel species selected for larger particles (28-35⯵m size fraction) while rejecting smaller ones (12-19⯵m). Whereas mussels did not appear to partition resources by size, mussel species exhibited resource partitioning of algal taxa (i.e., selectively feeding on different algal species; under flowing conditions: small centric diatoms were preferred by P. fasciolaris and Q. quadrula and avoided by P. alatus; Cryptomonas were preferred by P. fasciolaris and avoided by Q. quadrula and P. alatus; Chloromonas were preferred by P. alatus and avoided by P. fasciolaris). This study provides a novel mechanism, hydrodynamically mediated resource partitioning, in which the partitioning of resources occurs from within a flowing fluid rather than through the spatial or temporal partitioning of resources by organisms exploiting different microhabitats, to explain the existence of high mussel species richness within the same river reach (i.e., 24 species in this study). Unfortunately the species specific relationships noted above are likely vulnerable to climate change and changes in land use practice due to agriculture and urbanization.

We have tested the entire Keio collection of close to 4,000 single-gene knockouts in Escherichia coli for increased susceptibility to one of seven different antibiotics (ciprofloxacin, rifampin, vancomycin, ampicillin, sulfamethoxazole, gentamicin, or metronidazole). We used high-throughput screening of several subinhibitory concentrations of each antibiotic and reduced more than 65,000 data points to a set of 140 strains that display significantly increased sensitivities to at least one of the antibiotics, determining the MIC in each case. These data provide targets for the design of "codrugs" that can potentiate existing antibiotics. We have made a number of double mutants with greatly increased sensitivity to ciprofloxacin, and these overcome the resistance generated by certain gyrA mutations. Many of the gene knockouts in E. coli are hypersensitive to more than one antibiotic. Together, all of these data allow us to outline the cell's "intrinsic resistome," which provides innate resistance to antibiotics.

We investigated factors associated with quality of life (QOL) in children with eczema. We conducted a cross-sectional analysis of survey data from 224 parents of children with eczema attending a large, hospital-based pediatric clinic. Parents completed a validated eczema severity scale (Patient-Oriented Eczema Measure), a QOL scale (Infants' Dermatitis QOL Index or Children's Dermatology Life Quality Index), and a knowledge and understanding questionnaire. In adjusted multivariate analyses, worse eczema severity was associated with worse overall QOL (ß = 0.5; 95% confidence interval [CI] = [0.5, 0.6]), while a higher knowledge score was associated with better QOL (ß = -3.4; 95% CI = [-6.6, -0.2]). Similarly, even after adjustment for eczema severity, greater understanding of a child's individual treatment plan was associated with better QOL (ß = -0.7; 95% CI = [-1.4, -0.08]), while increased frequency of worrying about a child's eczema was associated with worse QOL (ß = 0.7; 95% CI = [0.03, 1.1]). These results suggest primary care providers may be able to influence QOL through optimal eczema management and family education.

OBJECTIVE: To test whether an eczema care plan (ECP) would improve provider documentation and management, decrease eczema severity, and increase patient quality of life (QOL) in the pediatric primary care setting. METHODS: We conducted a randomized controlled trial from June 2015 to September 2016 at a large hospital-based pediatric primary care clinic. Participants included children from 1 month to 16 years of age with a diagnosis of eczema. The intervention group received the ECP and the control group received usual care. Both groups completed a validated eczema severity scale (Patient-Oriented Eczema Measure [POEM]) and a QOL scale (Infant's Dermatitis Quality of Life Index [IDQOL]) or Children's Dermatology Life Quality Index [CDLQI]) before the visit and again ~1 month later. RESULTS: A total of 211 caregivers completed both the pre- and postintervention surveys (100 control group and 111 intervention group [94% completion]). Intervention group providers were more likely to recommend a comprehensive "step-up" plan (88%) vs 28%; P < .001, bleach baths (45%) vs 9%; P < .001, and wet wraps (50%) vs 7%; P < .001. They were also more likely to document providing a written plan to families (80%) vs 2%; P < .001. In the intervention and control groups, eczema severity and QOL improved between the pre- and postintervention periods. However, there was not a significant difference between the groups on either measure: POEM difference -0.8, 95% confidence interval (CI) -3.2 to 1.7; IDQOL difference -0.1, 95% CI -1.8 to 1.6; CDLQI difference 0.8, 95% CI -0.9 to 2.6. CONCLUSIONS: Intervention group providers documented more comprehensive eczema care than control group providers. Although patients improved on all measures in the postintervention period, the ECP did not augment that improvement.
