Methods: A cross-sectional survey was conducted of 134 ED providers (nurses [n = 126] and physicians [n = 8]) who were working in five Midwestern critical access hospitals (response rate 83%). Descriptive, correlational and stepwise regression analyses were employed to evaluate provider perceptions of 1) competency level in telehealth delivery, 2) patient health outcomes, 3) access to continuing education in telehealth, and 4) clinical influence of telehealth visit. Evaluation of preliminary set of N = 100 telehealth cases were assessed for influence of telehealth on clinical reasoning of attending physicians regarding patient disposition. Results: The majority (67%;n = 90) of participants had at least minimal experience with telehealth care delivery, with an average of 1 - 2 visits in teleneurology, and 3 - 4 visits in telebehavioral cases. Providers rated their overall mean competency level in telehealth care delivery as 3.01/5.00 based on a 5 point “novice (1) to expert” (5) scale. Mean scores for providers perceived competency level in 7 evidence-based sub-categories for telehealth care delivery were self-reported as relatively low to mid-range values, ranging from 2.64 - 3.57/5.00. Stepwise linear regression analysis of whether all providers “would recommend telehealth to their family and friends” revealed two predictors for model of best fit (n = 81;p 2 = 0.598): 1) their perceptions of telehealth experience compared to usual care;and 2) perceptions of patient health outcomes with telehealth compared to usual care. Providers rated “neutral” to “very unlikely” that they “would recommend telehealth to family and friends” (2.75/5.00;n = 122;91%). Attending physicians reported that for a majority of cases, telehealth visits influenced patient disposition and transfer decision-making (58.4%), and the influence of telehealth visits on patient disposition was statistically significantly higher for behavioral health cases (p Discussion: This study will be followed on to inform administrators/policy makers about 1) perceived level of competency of providers who implement tele-emergency care, 2) potential importance of telehealth equipment used and teamwork between rural providers and distant specialist, and 3) how use of telehealth may enhance ability of rural ED providers to improve quality of care. Perceived influence of telehealth on patient disposition is reported to be highest for telebehavioral patients. Healthcare educators need to place a priority on addressing provider competencies in telehealth through health professions degree programs and continuing education. Further research is needed to promote application and testing of evidence-based provider competencies in telehealth, and potentially relevant health communication models, to increase providers’ perceived efficacy and competency in telehealth care delivery, thus supporting high quality patient health outcomes.展开更多

The elderly subjects, compared to adult population, show a reduction in the diversity of the microbiota, characterized by a large interindividual variability, with lower numbers of Firmicutes, Bifidobacteria, Clostridium cluster XIV, Faecalibacterium Prausnitzii, Blautia coccoides-Eubacterium rectal and higher presence of Enterobacteriaceae and Bacteroidetes. These differences of the intestinal microbiota of the elderly may not necessarily be caused by aging, but they could be associated with the decline of the general state of health with malnutrition and with increased need for medication, such as antibiotics and nonsteroidal antiinflammatory drugs, situations that occur frequently in the elderly. Differences have been demonstrated in the composition of the microbiota between healthy elderly subjects and hospitalized or institutionalized elderly subjects. These findings which further indicates that the living conditions, health status, nutrition and drugs have a significant effect on the composition of the microbiota. According to the available knowledge, the use of probiotics is safe and could represent an useful intervention to prevent or treat antibioticassociated diarrhea, in addition to reducing the severity of symptoms, other than to help the management of constipation.展开更多

Methods A cross-sectional study was conducted in Longtan Community, Beijing. A total of 1512 individuals aged 60 years or over were selected by stratified cluster sampling. Data regarding the frequency of falls in the previous year, as well as circumstances, consequence and related factors of falls were collected from the elderly through face-to-face interviews with questionnaires in their home. Results The prevalence of falls was 18.0% on the average among 1512 participants, higher in women （20.1%） than in men （14.9%） （P=0.006）, and increased with age （Х^2 for trend=10.37, P=0.001）. The total rate of falls-induced injuries among the fallers was 37.7%. Falls usually resulted in soft-tissues bruises （58.7%）, fear of repeated episodes of falls （58.8%）, loss of independence and confidence in movement （35.7%） and even in hip fracture. In addition to the burden of medical care, falls also generated a big economic burden. Occurrence of falls was significantly associated with both intrinsic and extrinsic factors. The related factors of falls in the elderly included age≥60-70 years, femininity, less physical activities, fear of future falls, living alone, severely impaired vision, health problem-impacted activities of daily living, chronic diseases （diabetes, hypertension, postural hypotension, stroke sequela, cataract, arthritis, dementia and depression）, medications （psychoactive, anti-diabetic）, gait imbalance, high bed and faintly-lighted stairway. Conclusion The prevalence of falls among urban community-dwelling elderly in Beijing is closely associated with significant associated with intrinsic and extrinsic factors. Efforts to prevent falls in the elderly should be made at community level.展开更多

Effective HPV vaccines remain controversial and have poor uptake among many adolescent groups. Social media have potential for promoting the HPV vaccine, but little is known about the content or sentiment of social media discussions regarding the vaccine. The purpose of this study was to examine message, context, sentiment, and source characteristics of original HPV- and HPV vaccine-related Twitter posts (tweets) over a 3-month time period. This content mining study used publicly available data purchased from Twitter. One-thousand tweets were randomly selected from a sample of 45,260 English language tweets matching our search criteria and collected from December 2014-January 2015. Tweets were manually coded according to source, context, message, and sentiment characteristics using a coding document developed from previous research. Individuals posted just over half (55%) of tweets, whereas organizations posted 40%. More than half (57%) of all coded tweets were positive, and less than one-fifth were negative. Organizations’ tweets were more likely to be positive than individuals’ tweets. A temporal display of contextual events and tweet spikes demonstrates that positive tweets can increase during newsworthy events (e.g. FDA approval of Gardisil 9). The HPV vaccine was most often discussed under a cancer prevention message frame. In contrast with some existing research, discussions surrounding the HPV vaccine in original Twitter posts are largely positive. Our study reveals opportunities for adolescent health specialists to provide accurate, positive HPV vaccination information via Twitter.展开更多

Plant proteins interact with food components via protein-protein and protein-polysaccharide associations, and the formation of a matrix, which can entrap other food components such as water, lipids and flavors. These networks provide structural integrity to food products and can serve as important functional ingredients in processed foods. Intermolecular interactions of typical polysaccharides result either in simple associations or in the form of a double or triple helix. The linear double helical segments may then interact to form a super junction and a three-dimensional gel network. The formation of these structural networks takes place during processing and involves the transformation from a liquid or viscous sol into a solid material with elastic properties. Interests in the behavior of mixed gels center on the prospects of enhanced flexibility in their mechanical and structural properties compared to those of pure gels. Findings on molecular interactions between plant proteins （e.g., soy, canola and pea proteins） and polysaccharides （e.g., guar gum, carrageenan, and pectin） allow for the modification of physical and textural characteristics of mixed biopolymers to meet desired functional property.展开更多

Using a sample of 950 NCAA Division I athletes, it was found that 33.2% of athletes experienced symptoms of depression, contradicting findings from previous studies that have suggested a prevalence rate lower than the general college population. Female athletes （P = 0.00）, underclassmen （P = 0.01）, recently injured athletes （P = 0.05）, and in-season athletes （P = 0.05）, were all found to experience higher rates of depression symptoms than other athletes. It was found that 25.7% of athletes did not know how or where to access mental health treatment at their university, and 44.5% had received no mental health education from their athletic department. The results from this study suggest that depression is a more significant issue in college athletics than previously thought, and they highlight the need for continued improvements to be made in both the understanding of mental health issues in college athletics and the services that are provided to athletes.展开更多

Treatment with herbal products shows benefits in their use, as well as antioxidant and antifungal activities. Objective: to evaluate the antimicrobial action of 10% banana peel gel and the contraction of diabetic and venous wounds. Methods: individual, analytical, interventional, longitudinal, prospective, randomized study from February to December 2015. Five patients were included in the study;3 with venous ulcer and 2 with diabetic wound. Application of 10% green banana peel gel and weekly samples were performed. After six days, the second collection was performed. The samples were seeded in the Mannitol salt agar culture medium, MacConkey agar and Saboraund agar with chloramphenicol for isolation of cocci and Gram-positive and Gram-negative bacilli;and fungi. The total counts of bacteria were determined by PCA (Plate Count Agar) and measurement of the lesion margin. There was a reduction of microorganisms with the use of the gel in 53.57% of the patients, and reduction of wound areas in 48.1%.展开更多

This study investigated the association of HF severity, based on the New York Heart Association(NYHA) classes, with digital mobility outcomes(DMOs) and handgrip strength in older inpatients with HF.METHODS For this explorative analysis, hospital admission and discharge data from an ongoing, prospective cohort study were used. The sample included older participants with HF and a sub-sample of heart-healthy individuals. Participants were equipped with a wearable inertial measurement unit(IMU) system during mobility performance(balancing, sit-to-stand transfer,walking). We analyzed the association between 17 DMOs and HF severity with multiple linear regression models.RESULTS The total sample included 61 older participants(65–97 years of age, 55.7% female). Of all DMOs, only sway path in a semi-tandem stance position(m/s^(2)) showed a relevant association with NYHA classes(admission: β =-0.28, P = 0.09;discharge:β =-0.39, P = 0.02). Handgrip strength showed a trend towards a significant association(admission: β =-0.15, P = 0.10;discharge:β =-0.15, P = 0.19).CONCLUSIONS This is to our best knowledge the first analysis on the association of HF severity and IMU-based DMOs. Sway path and handgrip strength may be the most promising parameters for monitoring mobility aspects in treatment of HF.展开更多

A mixed group of athletes （n = 52） competing at national and international level and a matching genetic control group （n = 109） of volunteers were recruited. Participants were genotyped for ACTN3 and AMPD1 by polymerase chain reaction. There were no significant differences in ACTN3 genotype distribution between athletes performing Wingate test （38% RR, 46% RX, 16% XX） and controls （41.2% RR, 46% RX, 12.8% XX）. AMPD1 distribution was （73% CC, 27% CT, 0% TT） and in controls （73.2% CC, 25% CT, 1.8% TT）. Athletes performing Wingate test showed equal 33% frequency of RR/CC and RX/CC combination, and 12% RX/CT. Significantly higher （P 〈 0.05） peak power output （11.10 W kg1） was found in athletes with RX/CT combination compared to other combinations （range： 8.83-9.71 W kg-1） and in R-power （RR ＋ RX） and C-power （CC ＋ CT） dominant models （9.91 W kgl）. Mean power was higher （P 〈 0.05） in RX/CT combination （8.93 W kg-1） compared to RR/CC （7.75 W kg-1） and RR/CT （7.95 W kgl）. In conclusion, the low frequency of T AMPD1 allele in Bulgarian athletes might indicate that this mutant allele is related to the physical performance. The prevalence of R ACTN3 and C AMPD1 alleles suggests that they could contribute to anaerobic performance. Higher peak power in Wingate test is associated with RX/CT genotype combination and R- and C-power dominant models.展开更多

文摘The aim of the present systematic review is to summarize the existing knowledge about the human microbiota in the elderly and the effects of probiotics in elderly population. The elderly subjects, compared to adult population, show a reduction in the diversity of the microbiota, characterized by a large interindividual variability, with lower numbers of Firmicutes, Bifidobacteria, Clostridium cluster XIV, Faecalibacterium Prausnitzii, Blautia coccoides-Eubacterium rectal and higher presence of Enterobacteriaceae and Bacteroidetes. These differences of the intestinal microbiota of the elderly may not necessarily be caused by aging, but they could be associated with the decline of the general state of health with malnutrition and with increased need for medication, such as antibiotics and nonsteroidal antiinflammatory drugs, situations that occur frequently in the elderly. Differences have been demonstrated in the composition of the microbiota between healthy elderly subjects and hospitalized or institutionalized elderly subjects. These findings which further indicates that the living conditions, health status, nutrition and drugs have a significant effect on the composition of the microbiota. According to the available knowledge, the use of probiotics is safe and could represent an useful intervention to prevent or treat antibioticassociated diarrhea, in addition to reducing the severity of symptoms, other than to help the management of constipation.

文摘Objective To understand the prevalence, consequences and risk factors of falls among urban community-dwelling elderly in Beijing. Methods A cross-sectional study was conducted in Longtan Community, Beijing. A total of 1512 individuals aged 60 years or over were selected by stratified cluster sampling. Data regarding the frequency of falls in the previous year, as well as circumstances, consequence and related factors of falls were collected from the elderly through face-to-face interviews with questionnaires in their home. Results The prevalence of falls was 18.0% on the average among 1512 participants, higher in women （20.1%） than in men （14.9%） （P=0.006）, and increased with age （Х^2 for trend=10.37, P=0.001）. The total rate of falls-induced injuries among the fallers was 37.7%. Falls usually resulted in soft-tissues bruises （58.7%）, fear of repeated episodes of falls （58.8%）, loss of independence and confidence in movement （35.7%） and even in hip fracture. In addition to the burden of medical care, falls also generated a big economic burden. Occurrence of falls was significantly associated with both intrinsic and extrinsic factors. The related factors of falls in the elderly included age≥60-70 years, femininity, less physical activities, fear of future falls, living alone, severely impaired vision, health problem-impacted activities of daily living, chronic diseases （diabetes, hypertension, postural hypotension, stroke sequela, cataract, arthritis, dementia and depression）, medications （psychoactive, anti-diabetic）, gait imbalance, high bed and faintly-lighted stairway. Conclusion The prevalence of falls among urban community-dwelling elderly in Beijing is closely associated with significant associated with intrinsic and extrinsic factors. Efforts to prevent falls in the elderly should be made at community level.

文摘Genital human papilloma virus (HPV) is the most common sexually transmitted virus in the US. Effective HPV vaccines remain controversial and have poor uptake among many adolescent groups. Social media have potential for promoting the HPV vaccine, but little is known about the content or sentiment of social media discussions regarding the vaccine. The purpose of this study was to examine message, context, sentiment, and source characteristics of original HPV- and HPV vaccine-related Twitter posts (tweets) over a 3-month time period. This content mining study used publicly available data purchased from Twitter. One-thousand tweets were randomly selected from a sample of 45,260 English language tweets matching our search criteria and collected from December 2014-January 2015. Tweets were manually coded according to source, context, message, and sentiment characteristics using a coding document developed from previous research. Individuals posted just over half (55%) of tweets, whereas organizations posted 40%. More than half (57%) of all coded tweets were positive, and less than one-fifth were negative. Organizations’ tweets were more likely to be positive than individuals’ tweets. A temporal display of contextual events and tweet spikes demonstrates that positive tweets can increase during newsworthy events (e.g. FDA approval of Gardisil 9). The HPV vaccine was most often discussed under a cancer prevention message frame. In contrast with some existing research, discussions surrounding the HPV vaccine in original Twitter posts are largely positive. Our study reveals opportunities for adolescent health specialists to provide accurate, positive HPV vaccination information via Twitter.

文摘This study aimed to determine an overall prevalence rate for depression symptoms among National Collegiate Athletic Association （NCAA） Division I collegiate athletes while also assessing various risk factors that may increase an athlete＇s vulnerability to depression. Using a sample of 950 NCAA Division I athletes, it was found that 33.2% of athletes experienced symptoms of depression, contradicting findings from previous studies that have suggested a prevalence rate lower than the general college population. Female athletes （P = 0.00）, underclassmen （P = 0.01）, recently injured athletes （P = 0.05）, and in-season athletes （P = 0.05）, were all found to experience higher rates of depression symptoms than other athletes. It was found that 25.7% of athletes did not know how or where to access mental health treatment at their university, and 44.5% had received no mental health education from their athletic department. The results from this study suggest that depression is a more significant issue in college athletics than previously thought, and they highlight the need for continued improvements to be made in both the understanding of mental health issues in college athletics and the services that are provided to athletes.

文摘BACKGROUND Individuals with heart failure(HF) frequently experience limitations in mobility, but specific aspects of these limitations are not well understood. This study investigated the association of HF severity, based on the New York Heart Association(NYHA) classes, with digital mobility outcomes(DMOs) and handgrip strength in older inpatients with HF.METHODS For this explorative analysis, hospital admission and discharge data from an ongoing, prospective cohort study were used. The sample included older participants with HF and a sub-sample of heart-healthy individuals. Participants were equipped with a wearable inertial measurement unit(IMU) system during mobility performance(balancing, sit-to-stand transfer,walking). We analyzed the association between 17 DMOs and HF severity with multiple linear regression models.RESULTS The total sample included 61 older participants(65–97 years of age, 55.7% female). Of all DMOs, only sway path in a semi-tandem stance position(m/s^(2)) showed a relevant association with NYHA classes(admission: β =-0.28, P = 0.09;discharge:β =-0.39, P = 0.02). Handgrip strength showed a trend towards a significant association(admission: β =-0.15, P = 0.10;discharge:β =-0.15, P = 0.19).CONCLUSIONS This is to our best knowledge the first analysis on the association of HF severity and IMU-based DMOs. Sway path and handgrip strength may be the most promising parameters for monitoring mobility aspects in treatment of HF.
文摘Non-alcoholic fatty liver disease(NAFLD)has recently become a public health concern concurrent with the obesity crisis.Previous work has shown aberrant mitochondrial content/quality and autophagy in models of NAFLD,whereas exercise is known to improve these derangements.The purpose of this study was to examine the effect of different weight-loss modalities on hepatic mitochondrial content,autophagy and mitophagy in NAFLD.Forty-eight male C57BL/6J mice were divided into 1 of 4 groups:low fat diet(LFD,10%fat,18 weeks),high fat diet(HFD,60%fat diet,18 weeks),weight-loss by diet(D,60%fat diet for 10 weeks then 10%fat diet for 8 weeks)or weight-loss by diet and physical activity(D/PA,60%fat diet for 10 weeks,then 10%fat diet plus a running wheel for 8 weeks).Immunoblot data were analyzed by one-way analysis of variance(ANOVA)with significance denoted at p<0.05.COX-IV protein contents were approximately 50%less in HFD compared to LFD.D/PA had 50%more BNIP3 compared to HFD.PINK1 content was 40%higher in D and D/PA compared to LFD.PPARKIN/PARKIN levels were 40%lower in HFD,D,and D/PA compared to LFD.Whereas p-UbSer65 was 3-fold higher in HFD.LC3II/I ratio was 50%greater in HFD and D/PA,yet p62 protein content was 2.5 fold higher in HFD.High-fat diet causes disruptions in markers of mitochondrial quality control.Physical activity combined with diet were able to ameliorate these derangements and seemingly improve hepatic mitochondrial quality above control values.
文摘The aim of the study was to investigate ACTN3 （ct-actinin-3） and AMPD1 （adenosine monophosphate deaminase） polymorphism and genotype combinations in Bulgarian athletes competing in various sports and the relation to peak power output. A mixed group of athletes （n = 52） competing at national and international level and a matching genetic control group （n = 109） of volunteers were recruited. Participants were genotyped for ACTN3 and AMPD1 by polymerase chain reaction. There were no significant differences in ACTN3 genotype distribution between athletes performing Wingate test （38% RR, 46% RX, 16% XX） and controls （41.2% RR, 46% RX, 12.8% XX）. AMPD1 distribution was （73% CC, 27% CT, 0% TT） and in controls （73.2% CC, 25% CT, 1.8% TT）. Athletes performing Wingate test showed equal 33% frequency of RR/CC and RX/CC combination, and 12% RX/CT. Significantly higher （P 〈 0.05） peak power output （11.10 W kg1） was found in athletes with RX/CT combination compared to other combinations （range： 8.83-9.71 W kg-1） and in R-power （RR ＋ RX） and C-power （CC ＋ CT） dominant models （9.91 W kgl）. Mean power was higher （P 〈 0.05） in RX/CT combination （8.93 W kg-1） compared to RR/CC （7.75 W kg-1） and RR/CT （7.95 W kgl）. In conclusion, the low frequency of T AMPD1 allele in Bulgarian athletes might indicate that this mutant allele is related to the physical performance. The prevalence of R ACTN3 and C AMPD1 alleles suggests that they could contribute to anaerobic performance. Higher peak power in Wingate test is associated with RX/CT genotype combination and R- and C-power dominant models.
文摘The increasing availability of government data has prompted efforts to standardize data cataloging practices for enhanced accessibility and usability.The primary aim of this study is to descriptively assess data catalog and referenced dataset volume,metadata utilization,and thematic composition of United States DCAT compliant data catalogs across Federal,State,County,City,and Territory entities.Data collection involved compiling a list of relevant government agencies and data resources to identify data catalogs.DCAT compliance was then assessed,and metadata from compliant catalogs was extracted.Thematic mapping utilized Python packages RegEx and FuzzyWuzzy to categorize themes into eight standard categories.A combination of descriptive statistics and 1-way ANOVA tests were conducted to analyze dataset volume,metadata utilization,and reported themes.Of the 305 data catalogs identified,259 were found to be DCAT compliant.Federal entities exhibited the highest DCAT compliance rates(92.3%),followed by County(88.1%),City(86.9%),and State(77.0%),while Territory(0%)had no compliant data catalogs.Descriptive analysis revealed that federal DCAT compliant data catalogs(n=59)had the highest average number of data assets across their data catalogs(μ=1,133.2)with the predominant themes being transportation at 21.2%(n=14,785)and geospatial at 15.4%(n=10,761).While county data catalogs(n=52)had the lowest average(μ=232.6)with the most referenced themes being geospatial at 77.6%(n=8450)and finance at 2.4%(n=270).After applying thematic mapping to eight standard categories,the three most dominant themes across all entities were transportation at 38.1%(n=16,504),natural resources with 19.6%(n=8,501),and health and safety with 14.7%(n=6,367).These findings underscore the widespread adoption of the DCAT standard across government entities,with notable gaps at the territorial level.Federal and state entities exhibited the highest data catalog and dataset volumes,while metadata utilization remained relatively consistent across all entity levels.The thematic analysis highlights the importance of standardization efforts to enhance thematic consistency and facilitate effective data interpretation.Further collaboration and investment are warranted to address gaps in catalog coverage and establish standardized data cataloging practices to maximize the accessibility and usability of these data catalogs along with their referenced datasets.
文摘Stone,sand,and gravel mining accounts for 80%of all mining operations.Maintaining a skilled labor force is essential for this large and growing mining sector.Occupational injuries negatively impact worker health and well-being and are costly.Additionally,injuries may impact workers'job satisfaction and their desire to seek other employment.The impact of work-related occupational injuries on job satisfaction and turnover intention has not been explored in stone,sand,and gravel mining operations.This study analyzed cross-sectional data from 459 workers employed in the stone,sand,and gravel mining industry in the midwestern United States.Mplus was used to complete path analysis to assess a hypothesized model and its relationships.Analyses determined the model was a good fit for the data,occupational injuries negatively impacted worker job satisfaction,job satisfaction negatively impacted turnover intention,and job satisfaction mediated the relationship between occupational injuries and turnover intention.These findings confirm posited hypotheses and provide evidence that occupational injuries not only harm workers but also result in diminished job satisfaction and ultimately turnover intention,important business outcomes for the stone,sand,and gravel mining industry.
