Background Hand hygiene is considered one of the most important infection control measures in human healthcare settings, but there is little information available regarding hand hygiene frequency and technique used in veterinary clinics. The objectives of this study were to describe hand hygiene practices associated with routine appointments in companion animal clinics in Ontario, and the effectiveness of a poster campaign to improve hand hygiene compliance. Results Observation of hand hygiene practices was performed in 51 clinics for approximately 3 weeks each using 2 small wireless surveillance cameras: one in an exam room, and one in the most likely location for hand hygiene to be performed outside the exam room following an appointment. Data from 38 clinics were included in the final analysis, including 449 individuals, 1139 appointments before and after the poster intervention, and 10894 hand hygiene opportunities. Overall hand hygiene compliance was 14% (1473/10894), while before and after patient contact compliance was 3% (123/4377) and 26% (1145/4377), respectively. Soap and water was used for 87% (1182/1353) of observed hand hygiene attempts with a mean contact time of 4 s (median 2 s, range 1-49 s), while alcohol-based hand rub (ABHR) was used for 7% (98/1353) of attempts with a mean contact time of 8 s (median 7 s, range 1-30 s). The presence of the posters had no significant effect on compliance, although some staff reported that they felt the posters did increase their personal awareness of the need to perform hand hygiene, and the posters had some effect on product contact times. Conclusions Overall hand hygiene compliance in veterinary clinics in this study was low, and contact time with hand hygiene products was frequently below current recommendations. Use of ABHR was low despite its advantages over hand washing and availability in the majority of clinics. The poster campaign had a limited effect on its own, but could still be used as a

Full Text Available In-person structured observation is considered the best approach for measuring hand hygiene behavior, yet is expensive, time consuming, and may alter behavior. Video surveillance could be a useful tool for objectively monitoring hand hygiene behavior if validated against current methods.Student hand cleaning behavior was monitored with video surveillance and in-person structured observation, both simultaneously and separately, at four primary schools in urban Kenya over a study period of 8 weeks.Video surveillance and in-person observation captured similar rates of hand cleaning (absolute difference <5%, p = 0.74. Video surveillance documented higher hand cleaning rates (71% when at least one other person was present at the hand cleaning station, compared to when a student was alone (48%; rate ratio  = 1.14 [95% CI 1.01-1.28]. Students increased hand cleaning rates during simultaneous video and in-person monitoring as compared to single-method monitoring, suggesting reactivity to each method of monitoring. This trend was documented at schools receiving a handwashing with soap intervention, but not at schools receiving a sanitizer intervention.Video surveillance of hand hygiene behavior yields results comparable to in-person observation among schools in a resource-constrained setting. Video surveillance also has certain advantages over in-person observation, including rapid data processing and the capability to capture new behavioral insights. Peer influence can significantly improve student hand cleaning behavior and, when possible, should be exploited in the design and implementation of school hand hygiene programs.

Although proper hand hygiene among health care workers is an important component of efforts to prevent health care-associated infection, there are few data available on adherence to hand hygiene practices in Japan. The aim of this study was to examine hand hygiene adherence at teaching hospitals in Japan. An observational study was conducted from July to November 2011 in 4 units (internal medicine, surgery, intensive care, and/or emergency department) in 4 geographically diverse hospitals (1 university hospital and 3 community teaching hospitals) in Japan. Hand hygiene practice before patient contact was assessed by an external observer. In a total of 3545 health care worker-patient observations, appropriate hand hygiene practice was performed in 677 (overall adherence, 19%; 95% confidence interval, 18%-20%). Subgroup rates of hand hygiene adherence were 15% among physicians and 23% among nurses. The ranges of adherence were 11% to 25% between hospitals and 11% to 31% between units. Adherence of the nurses and the physicians to hand hygiene was correlated within each hospital. There was a trend toward higher hand hygiene adherence in hospitals with infection control nurses, compared with hospitals without them (29% versus 16%). The hand hygiene adherence in Japanese teaching hospitals in our sample was low, even lower than reported mean values from other international studies. Greater adherence to hand hygiene should be encouraged in Japan.

Monitoring hand hygiene compliance among health care personnel (HCP) is an essential element of hand hygiene promotion programs. Observation by trained auditors is considered the gold standard method for establishing hand hygiene compliance rates. Advantages of observational surveys include the unique ability to establish compliance with all of the World Health Organization "My 5 Moments for Hand Hygiene" initiative Moments and to provide just-in-time coaching. Disadvantages include the resources required for observational surveys, insufficient sample sizes, and nonstandardized methods of conducting observations. Electronic and camera-based systems can monitor hand hygiene performance on all work shifts without a Hawthorne effect and provide significantly more data regarding hand hygiene performance. Disadvantages include the cost of installation, variable accuracy in estimating compliance rates, issues related to acceptance by HCP, insufficient data regarding their cost-effectiveness and influence on health care-related infection rates, and the ability of most systems to monitor only surrogates for Moments 1, 4, and 5. Increasing evidence suggests that monitoring only Moments 1, 4, and 5 provides reasonable estimates of compliance with all 5 Moments. With continued improvement of electronic monitoring systems, combining electronic monitoring with observational methods may provide the best information as part of a multimodal strategy to improve and sustain hand hygiene compliance rates among HCP.

The realization that solar activity probably undergoes changes in qualitative character on time scales greater than the 11 or 22 year cycle but short compared to the duration of recorded history gives renewed importance to historical documents describing the state of solar activity. Modern eclipse observation reveal the presence of solar acitivity through the appearance of coronal structures and prominences. It has been widely remarked that eclipse records prior to the 18th century are uniformly silent on these conspicuous solar eclipse features, raising the possibility, however unlikely, that a change in solar activity has occurred which rendered them only recently noticeable. We present here material from ancient Chinese sources, primarily astrological, that describe phenomena attending solar eclipses that are almost certainly coronal structures and prominences. Thus, these aspects of the present character of solar activity have apparently occurred at other times in history, if not continuously. (orig.)

Hand hygiene has the biggest impact and is the least expensive way to prevent and control health care-associated infections. In this study, we assessed the effectiveness of the multimodal strategy of the World Health Organization to improve health care-associated infection rates, hand hygiene compliance, and the related knowledge of health care professionals in a Brazilian university hospital. We observed the necessity for an alternative approach in hospitals with high staff turnover and low attendance of educational sessions.

A survey pilot asked patients to observe the hand hygiene compliance of their health care providers. Patients returned 75.1% of the survey cards distributed, and the overall hand hygiene compliance was 96.8%. Survey results and patient commentary were used to motivate hand hygiene compliance. The patient-as-observer approach appeared to be a viable alternative for hand hygiene auditing in an ambulatory care setting because it educated, engaged, and empowered patients to play a more active role in their own health care.

Parents experiencing early parenting difficulties often seek support through parenting programs. Characteristics of mothers seeking parenting support and information at an early parenting center in Victoria, Australia and the relationships between these factors and parenting behavior were explored using an observational measure of parent-child interaction. Participants were 43 mothers and children attending a 5-day residential parenting program at the Queen Elizabeth Centre. Maternal and sociodemographic data as well as an observational mother-child interaction task from the Nursing Child Assessment Satellite Training Parent Child Interaction Teaching scale were completed and scored on the first day of the program. Certain maternal factors and experiences were associated with observed parenting behavior. Poorer maternal sleeping quality, unplanned pregnancy and preterm birth were all associated with less optimal parenting behavior in certain domains. Findings are discussed with reference to the impact of past experiences around pregnancy and birth as well as the current context and well-being of mothers attending early parenting centers.

To describe hand-hygiene practices in pediatric long-term care (pLTC) facilities and to identify observed barriers to, and potential solutions for, improved infection prevention. Observational study using (i) the World Health Organization's '5 Moments for Hand Hygiene' validated observation tool to record indications for hand hygiene and adherence; and (ii) individual logs of subjective impressions of behavioral and/or systemic barriers witnessed during direct observation. Staff in three pLTC facilities (284 beds total) were observed by two trained nurses 1 day a week for 3 weeks in February and March 2015. Direct providers of health, therapeutic and rehabilitative care, and other staff responsible for social and academic activities for children with complex, chronic medical conditions. Hand-hygiene indications, adherence and barriers. Hand hygiene was performed for 40% of the 847 indications observed and recorded. Adherence increased at one site and decreased in the other two sites during the study period. Adherence appeared to be influenced by individuals' knowledge, attitudes, beliefs and work setting. Poor hand-hygiene adherence was observed overall. Specific barriers were identified, which suggest a contextual approach to the interpretation of results indicated in this uniquely challenging setting. We offer some practical suggestions for overcoming those barriers or mitigating their effect. Ultimately, an adaptation of the '5 Moments for Hand Hygiene' may be necessary to improve infection prevention in pLTC. © The Author 2015.

Τhe "March 2015 - Planetary Observation Project (POP)" was a series of talks and hands-on workshops focused on planetary observation organized in March 2015 by the planetary section of the Hellenic Amateur Astronomy Association. Building on our previous experience (Voutyras et al. 2013), which also includes more than 500 attendants in our 2013-2014 series of lectures in Astronomy, we identified that there is a lack of more focused lectures/workshops on observing techniques. In particular, POP's structure included two talks and two workshops aiming to inspire and educate astronomy enthusiasts. The talks tried to stimulate the participants about the importance of ground-based observations by presenting the most current scientific news and puzzling problems that we are facing in the observation of planets. During the hands-on workshops the beauty of planetary observation was used to inspire participants. However, we trained participants on observing techniques and image processing to enable them to produce scientifically useful results. All POP's events were open to the public and free, meaning both out-of-charge and freely available material provided to the participants (through our website). The project offered attendants unique experiences that may have a significant impact with potential lifelong benefits. In this work we present an overview of the project structure that may work as a prototype for similar outreach programs.

The dynamics of sensorimotor cortical oscillations during the observation of hand movements: an EEG study.

Directory of Open Access Journals (Sweden)

Pietro Avanzini

Full Text Available BACKGROUND: The observation of action done by others determines a desynchronization of the rhythms recorded from cortical central regions. Here, we examined whether the observation of different types of hand movements (target directed, non-target directed, cyclic and non-cyclic elicits different EEG cortical temporal patterns. METHODOLOGY: Video-clips of four types of hand movements were shown to right-handed healthy participants. Two were target directed (grasping and pointing motor acts; two were non-target directed (supinating and clenching movements. Grasping and supinating were performed once, while pointing and clenching twice (cyclic movements. High-density EEG was recorded and analyzed by means of wavelet transform, subdividing the time course in time bins of 200 ms. The observation of all presented movements produced a desynchronization of alpha and beta rhythms in central and parietal regions. The rhythms desynchronized as soon as the hand movement started, the nadir being reached around 700 ms after movement onset. At the end of the movement, a large power rebound occurred for all bands. Target and non-target directed movements produced an alpha band desynchronization in the central electrodes at the same time, but with a stronger desynchronization and a prolonged rebound for target directed motor acts. Most interestingly, there was a clear correlation between the velocity profile of the observed movements and beta band modulation. SIGNIFICANCE: Our data show that the observation of motor acts determines a modulation of cortical rhythm analogous to that occurring during motor act execution. In particular, the cortical motor system closely follows the velocity of the observed movements. This finding provides strong evidence for the presence in humans of a mechanism (mirror mechanism mapping action observation on action execution motor programs.

Aim: Every year, millions of people around the world suffer from different infectious diseases, considerable part of which are hospital-acquired infections. WHO considers hand hygiene as a priority measure aimed to reduce the level of infection. We evaluated various aspects related to the situational behavior and prioritization regarding hand hygiene measures among the healthcare workers of Ukraine. Method: Identification of system mistakes in hand hygiene was carried out first of all by direct and indirect observation of the activities of medical and pharmaceutical personnel in their everyday practice as well as during their participation in trainings on routine hand hygiene. Questionnaires also were used to estimate the level of hand hygiene compliance of participants of the study. During this period 112 training courses, 315 master-classes and presentations on proper hand hygiene were realized. The target audience included health care workers of medical centers, clinics, maternity hospitals, health care organizations and staff of pharmacies and pharmaceutical manufacturing enterprises in all regions of Ukraine. 638 respondents took part in anonymous survey on hand hygiene practice. Results: The most common mistakes were to regard hand washing and hand disinfection equally, to wash hands before doing a hand disinfection, to neglect the five moments for hand hygiene and to ignore hand hygiene before and after wearing protective gloves. Practitioners, medical attendants, pharmacy and pharmaceutical industry workers highlighted the need for practical and understandable instructions of various hand hygiene procedures, including the clarification of the possible technical mistakes. This became a ground for us to create individual master classes on hand hygiene for each cluster of healthcare workers. Conclusions: Changing hand hygiene behavior and attitude is possible by beginning to observe clinical practice and by involving healthcare workers in teaching and training

Indoor environments provide sources of exposure to organophosphate flame retardants (PFRs), which are artificially synthesized fire-protecting agents used as additives in interior products. As public spaces, hotels are required to meet stricter fire-precaution criteria. As such, room attendants may be exposed to higher levels of PFRs. Our goal was to characterize the exposure of hotel room attendants to PFRs by measuring metabolites in their urine and the corresponding parent PFRs in dust and hand-wipes collected from 27 hotels located in Wuhan City, China. The exposure of the attendants was found to be omnipresent: urinary metabolites of PFRs, such as DPHP (diphenyl phosphate), BDCIPP (bis(1,3-dichloro-2-propyl) phosphate), and DoCP (di-o-cresyl phosphate) & DpCP (di-p-cresyl phosphate) were detected with high frequency (87%, 79% and 87%, respectively). We observed that metabolites in post-shift urine were consistently present at higher levels than those in the first morning voids (p  7 stories) had significantly higher BDCIPP and DPHP concentrations than those from low-rise buildings. A possible reason is that high-rise buildings may use high-grade fireproof building materials to meet stricter fire restrictions. Overall, these results indicate that PFRs exposure in hotels is a contributor to the personal exposure of hotel room attendants. Copyright © 2018 Elsevier Ltd. All rights reserved.

Social impairments in individuals with autism spectrum disorders (ASD) may be in part due to difficulty perceiving and recognizing the actions of others. Evidence from imitation studies, which involves both observation and execution of an action, suggests differences, in individuals with ASD, between the ability to imitate goal-directed actions involving objects (transitive actions) and the ability to imitate actions that do not involve objects (intransitive actions). In the present study, we examined whether there were differences in how ASD adolescents encoded transitive and intransitive actions compared to typically developing (TD) adolescents, by having participants view videos of a hand reaching across a screen toward an object or to where an object would be while functional magnetic resonance images were collected. Analyses focused on areas within the action observation network (AON), which is activated during the observation of actions performed by others. We hypothesized that the AON would differentiate transitive from intransitive actions only in the ASD group. However, results revealed that object presence modulated activity in the right inferior frontal gyrus and supramarginal gyrus of the TD group, a differentiation that was not seen in the ASD group. Furthermore, there were no significant group differences between the TD and ASD groups in any of the conditions. This suggests that there is not a global deficit of the AON in individuals with ASD while observing transitive and intransitive actions. © 2015 International Society for Autism Research, Wiley Periodicals, Inc.

Personality traits affect teaching performance of attending physicians: results of a multi-center observational study.

Full Text Available BACKGROUND: Worldwide, attending physicians train residents to become competent providers of patient care. To assess adequate training, attending physicians are increasingly evaluated on their teaching performance. Research suggests that personality traits affect teaching performance, consistent with studied effects of personality traits on job performance and academic performance in medicine. However, up till date, research in clinical teaching practice did not use quantitative methods and did not account for specialty differences. We empirically studied the relationship of attending physicians' personality traits with their teaching performance across surgical and non-surgical specialties. METHOD: We conducted a survey across surgical and non-surgical specialties in eighteen medical centers in the Netherlands. Residents evaluated attending physicians' overall teaching performance, as well as the specific domains learning climate, professional attitude, communication, evaluation, and feedback, using the validated 21-item System for Evaluation of Teaching Qualities (SETQ. Attending physicians self-evaluated their personality traits on a 5-point scale using the validated 10-item Big Five Inventory (BFI, yielding the Five Factor model: extraversion, conscientiousness, neuroticism, agreeableness and openness. RESULTS: Overall, 622 (77% attending physicians and 549 (68% residents participated. Extraversion positively related to overall teaching performance (regression coefficient, B: 0.05, 95% CI: 0.01 to 0.10, P = 0.02.

Full Text Available Objective. To assess the effect that a training intervention for traditional birth attendants (TBAs in Guatemala had on the detection of obstetric complications, the referral of patients with complications to the formal health care system, and, ultimately, those patients' utilization of essential obstetric care services. Methods. Using a quasi-experimental design, a surveillance system of births was implemented to collect population-based information from 3 518 women between 1990 and 1993. All women were interviewed postpartum by physicians. There were three key independent variables in our study: 1 geographical area (intervention community and non-intervention community, 2 time in relation to the training intervention (before or after, and 3 presence or absence of a TBA at the time of the complication. The key dependent variables for women interviewed were 1 development of an obstetric complication, 2 detection of the problem by the TBA, 3 referral to a health facility, 4 compliance with referral, and 5 use of services. Results. The incidence of postpartum complications decreased after the intervention, controlling for intervention community. On the other hand, after the intervention TBAs were less likely to recognize most maternal complications, and referral rates did not increase significantly. The likelihood of using health care services increased six-fold among women who were not attended by TBAs, and no increase was observed among those who were attended by TBAs. Conclusion. Training TBAs may have had a positive effect on the rate, detection, and referral of postpartum complications. However, the evidence is less convincing for overall increases in the detection of complications, in referral to the formal health care system, and in the utilization of essential obstetric services among women attended by TBAs.

Bangladeshi communities have historically used ash and soil as handwashing agents. A structured observation study and qualitative interviews on the use of ash/soil and soap as handwashing agents were conducted in rural Bangladesh to help develop a handwashing promotion intervention. The observations were conducted among 1,000 randomly selected households from 36 districts. Fieldworkers observed people using ash/soil to wash their hand(s) on 13% of occasions after defecation and on 10% after cleaning a child's anus. This compares with 19% of people who used soap after defecation and 27% after cleaning a child who defecated.

A variety of hand hygiene monitoring programs (HHMPs) have come into use in hospitals throughout the world. In the present study, we compare continuous closed circle television (CCTV) with overt observation for monitoring the hand hygiene compliance of health care workers (HCWs) in a general intensive care unit (GICU). This is a cross-sectional and comparative study. In this study, we use a novel hand hygiene CCTV monitoring system for hand hygiene performance monitoring. The study population incorporated all the GICU HCWs, including registered nurses, staff physicians, and auxiliary workers. All HCWs of our GICU were observed, including ICU registered nurses, ICU staff physicians, and auxiliary workers participated in the present study. Overall, each observer team did 50 sessions in each arm of the study. Total number of hand hygiene opportunities was approaching 500 opportunities. The compliance rates when only overt observations were performed was higher than when only covert observations were performed with a delta of approximately 10% (209 out of 590 [35.43%] vs 130 out of 533 [24.39%]; P hand hygiene. However, there is no clear basis for incorporating a CCTV observation modality into a health care system that already operates an overt observation program. We have shown that CCTV methodology records a different distribution of opportunities for performing hand hygiene and of actual performances of hand hygiene compared with overt observation.

Hand hygiene is an important component in infection control to protect patient safety and reduce health care-associated infection. Our aim was to evaluate the efficacy of different social media on the promotion of a hand hygiene (HH) program. The observational study was conducted from May 5 to December 31, 2014, at a 2600-bed tertiary care hospital. A 3-minute video of an HH campaign in 8 languages was posted to YouTube. The Chinese version was promoted through three platforms: the hospital website, the hospital group email, and the Facebook site of a well-known Internet illustrator. The video traffic was analyzed via Google Analytics. HH compliance was measured in November 2013 and 2014. There were 5252 views of the video, mainly of the Chinese-language version (3509/5252, 66.81%). The NTUH website had 24,000 subscribers, and 151 of them viewed the video (connection rate was 151/24,000, 0.63%). There were 9967 users of the hospital email group and the connection rate was 0.91% (91/9967). The connection rate was 6.17% (807/13,080) from Facebook, significantly higher than the other 2 venues (both P<.001). HH compliance sustained from 83.7% (473/565) in 2013 to 86.7% (589/679) in 2014 (P=.13) among all HCWs. Facebook had the highest connection rate in the HH video campaign. The use of novel social media such as Facebook should be considered for future programs that promote hand hygiene and other healthy behaviors.

Brain lateralization is a common term used to describe dominance of one brain hemisphere over another for a specific function. The right hand dominance in writing, controlled by the left hemisphere, is preceded by development of communicative gesticulation and followed by development of speech in the same hemisphere. We assumed that some people are not aware of their own capability of using the other hand for tasks involving fine motor sequential movements. To prove this hypothesis, the participants were asked to perform one trained task (writing) and one less-trained task (drawing) with a dominant and a non-dominant hand. The final sample was comprised of 1189 children from 14 elementary schools and 8 high schools in the Osijek area, of which 685 elementary school children were attending 1st to 4th grade and 504 high school children were attending 3rd and 4th grade. The participants were asked to write two words, draw a specific object (a vase with flowers) and fill out a questionnaire with 10 questions concerning the classification of handedness and cerebral hemisphere dominance. The self-reported cerebral lateralization assessed in the questionnaire was compared with the drawing and the writing performance. The self-reported and objectively measured hand dominance deviated in the cases of the ambidextrous who consider themselves right-handers. Given the fact that the number of ambidextrous persons was greater in elementary schools than in high schools, we concluded how training of the right hand decreases the ability of using both hands equally for either of the tested functions - writing and drawing.

The Community College Effect Revisited: The Importance of Attending to Heterogeneity and Complex Counterfactuals*

Brand, Jennie E.; Pfeffer, Fabian T.; Goldrick-Rab, Sara

2015-01-01

Community colleges are controversial educational institutions, often said to simultaneously expand college opportunities and diminish baccalaureate attainment. We assess the seemingly contradictory functions of community colleges by attending to effect heterogeneity and to alternative counterfactual conditions. Using data on postsecondary outcomes of high school graduates of Chicago Public Schools, we find that enrolling at a community college penalizes more advantaged students who otherwise would have attended four-year colleges, particularly highly selective schools; however, these students represent a relatively small portion of the community college population, and these estimates are almost certainly biased. On the other hand, enrolling at a community college has a modest positive effect on bachelor's degree completion for disadvantaged students who otherwise would not have attended college; these students represent the majority of community college goers. We conclude that discussions among scholars, policymakers, and practitioners should move beyond considering the pros and cons of community college attendance for students in general to attending to the implications of community college attendance for targeted groups of students.

Full Text Available The existing attendance system still has drawbacks, namely the queue in front of the finger scanner, the attendance data are not integrated with Human Resources Systems, and also the employees who work outside the office cannot get in the attendance system to roll presence. In the other hand, everyone has the mobile devices and all the mobile devices will be embedded a finger scanner in the future. In this paper, it is proposed the absence system using one own device. The finger scanner and coordinate Global Position System (GPS are used as inputs for the attendance system that integrated with payroll system and human resource management tools. Application base on android platform is developed because the android is the most platforms that have been using in the most mobile devices. Using our proposed methodology, the employee can roll presence using their mobile devices and the do not need to be in queue and the employees who work outside the office also can roll presence. Research showed that proposed methodology can be used for the next generation attendance system.

Effect of hand sanitizer location on hand hygiene compliance.

Cure, Laila; Van Enk, Richard

2015-09-01

Hand hygiene is the most important intervention to prevent infection in hospitals. Health care workers should clean their hands at least before and after contact with patients. Hand sanitizer dispensers are important to support hand hygiene because they can be made available throughout hospital units. The aim of this study was to determine whether the usability of sanitizer dispensers correlates with compliance of staff in using the sanitizer in a hospital. This study took place in a Midwest, 404-bed, private, nonprofit community hospital with 15 inpatient care units in addition to several ambulatory units. The usability and standardization of sanitizers in 12 participating inpatient units were evaluated. The hospital measured compliance of staff with hand hygiene as part of their quality improvement program. Data from 2010-2012 were analyzed to measure the relationship between compliance and usability using mixed-effects logistic regression models. The total usability score (P = .0046), visibility (P = .003), and accessibility of the sanitizer on entrance to the patient room (P = .00055) were statistically associated with higher observed compliance rates. Standardization alone showed no significant impact on observed compliance (P = .37). Hand hygiene compliance can be influenced by visibility and accessibility of dispensers. The sanitizer location should be part of multifaceted interventions to improve hand hygiene. Copyright © 2015 Association for Professionals in Infection Control and Epidemiology, Inc.

We measured medical students' and resident trainees' hand hygiene behaviour, knowledge and attitudes in order to identify important predictors of hand hygiene behaviour in this population. An anonymous, web-based questionnaire was distributed to medical students and residents at Stanford University School of Medicine in August of 2012. The questionnaire included questions regarding participants' behaviour, knowledge, attitude and experiences about hand hygiene. Behaviour, knowledge and attitude indices were scaled from 0 to 1, with 1 representing superior responses. Using multivariate regression, we identified positive and negative predictors of superior hand hygiene behaviour. We investigated effectiveness of interventions, barriers and comfort reminding others. 280 participants (111 students and 169 residents) completed the questionnaire (response rate 27.8%). Residents and medical students reported hand hygiene behaviour compliance of 0.45 and 0.55, respectively (p=0.02). Resident and medical student knowledge was 0.80 and 0.73, respectively (p=0.001). The attitude index for residents was 0.56 and 0.55 for medical students. Regression analysis identified experiences as predictors of hand hygiene behaviour (both positive and negative influence). Knowledge was not a significant predictor of behaviour, but a working gel dispenser and observing attending physicians with good hand hygiene practices were reported by both groups as the most effective strategy in influencing trainees. Medical students and residents have similar attitudes about hand hygiene, but differ in their level of knowledge and compliance. Concerns about hierarchy may have a significant negative impact on hand hygiene advocacy. Published by the BMJ Publishing Group Limited.

Hand hygiene reduces healthcare-associated infections, and several recent publications have examined hand hygiene in the perioperative period. Our institution's policy is to perform hand hygiene before and after patient contact. However, observation suggests poor compliance. This is a retrospective review of a quality improvement database showing the effect of personal gel dispensers on perioperative hand hygiene compliance on a regional anesthesia team. Healthcare providers assigned to the Acute Pain Service were observed for compliance with hand hygiene policy during a quality improvement initiative. Provider type and compliance were prospectively recorded in a database. Team members were then given a personal gel dispensing device and again observed for compliance. We have retrospectively reviewed this database to determine the effects of this intervention. Of the 307 encounters observed, 146 were prior to implementing personal gel dispensers. Compliance was 34%. Pre- and post-patient contact compliances were 23 and 43%, respectively. For 161 encounters after individual gel dispensers were provided, compliance was 63%. Pre- and post-patient contact compliances were 53 and 72%, respectively. Improvement in overall compliance from 34 to 63% was significant. On the Acute Pain Service, compliance with hand hygiene policy improves when individual sanitation gel dispensing devices are worn on the person.

Cell phone use behaviors are known to vary across demographic sub-groups and geographic locations. This study examined whether universal hand-held calling while driving bans were associated with lower road-side observed hand-held cell phone conversations across drivers of different ages (16-24, 25-59, ≥60 years), sexes, races (White, African American, or other), ruralities (suburban, rural, or urban), and regions (Northeast, Midwest, South, and West). Data from the 2008-2013 National Occupant Protection Use Survey were merged with states' cell phone use while driving legislation. The exposure was presence of a universal hand-held cell phone ban at time of observation. Logistic regression was used to assess the odds of drivers having a hand-held cell phone conversation. Sub-groups differences were assessed using models with interaction terms. When universal hand-held cell phone bans were effective, hand-held cell phone conversations were lower across all driver demographic sub-groups and regions. Sub-group differences existed among the sexes (p-value, phone bans, the adjusted odds ratio (aOR) of a driver hand-held phone conversation was 0.34 [95% confidence interval (CI): 0.28, 0.41] for females versus 0.47 (CI 0.40, 0.55) for males and 0.31 (CI 0.25, 0.38) for drivers in Western states compared to 0.47 (CI 0.30, 0.72) in the Northeast and 0.50 (CI 0.38, 0.66) in the South. The presence of universal hand-held cell phone bans were associated lower hand-held cell phone conversations across all driver sub-groups and regions. Hand-held phone conversations were particularly lower among female drivers and those from Western states when these bans were in effect. Public health interventions concerning hand-held cell phone use while driving could reasonably target all drivers.

In today's security conscious society the efficiency of biometric systems has an increasing tendency to replace the classic but less effective keys and passwords. Hand geometry readers are popular biometrics used for acces control and time and attendance applications. One of their weaknesses is vulnerability to spoofing using fake hands (latex, play-doh or dead-hands). The object of this paper is to design a feature to be added to the hand geometry scanner in order to detect vitality in the hand, reducing the possibilities for spoofing. This paper demonstrates how the hand reader was successfully spoofed and shows the implementation of the vitality detection feature through an inexpensive but efficient electronic design. The method used for detection is photo-plethysmography. The Reflectance Sensor built is of original conception. After amplifying, filtering and processing the sensor's signal, a message is shown via an LCD display, concerning the liveness of the hand and the pulse rate.

Effects of context on visuomotor interference depends on the perspective of observed actions.

Directory of Open Access Journals (Sweden)

Marta Bortoletto

Full Text Available Visuomotor interference occurs when the execution of an action is facilitated by the concurrent observation of the same action and hindered by the concurrent observation of a different action. There is evidence that visuomotor interference can be modulated top-down by higher cognitive functions, depending on whether own performed actions or observed actions are selectively attended. Here, we studied whether these effects of cognitive context on visuomotor interference are also dependent on the point-of-view of the observed action. We employed a delayed go/no-go task known to induce visuomotor interference. Static images of hand gestures in either egocentric or allocentric perspective were presented as "go" stimuli after participants were pre-cued to prepare either a matching (congruent or non-matching (incongruent action. Participants performed this task in two different cognitive contexts: In one, they focused on the visual image of the hand gesture shown as the go stimulus (image context, whereas in the other they focused on the hand gesture they performed (action context. We analyzed reaction times to initiate the prepared action upon presentation of the gesture image and found evidence of visuomotor interference in both contexts and for both perspectives. Strikingly, results show that the effect of cognitive context on visuomotor interference also depends on the perspective of observed actions. When focusing on own-actions, visuomotor interference was significantly less for gesture images in allocentric perspective than in egocentric perspective; when focusing on observed actions, visuomotor interference was present regardless of the perspective of the gesture image. Overall these data suggest that visuomotor interference may be modulated by higher cognitive processes, so that when we are specifically attending to our own actions, images depicting others' actions (allocentric perspective have much less interference on our own actions.

Consistent hand hygiene is key to reducing health care-associated infections (HAIs) and assessing compliance with hand hygiene protocols is vital for hospital infection control staff. A new automated hand hygiene compliance system (HHCS) was trialed as an alternative to human observers in an intensive care unit and an intensive care stepdown unit at a hospital facility in the northeastern United States. Using a retrospective cohort design, researchers investigated whether implementation of the HHCS resulted in improved hand hygiene compliance and a reduction in common HAI rates. Pearson χ 2 tests were used to assess changes in compliance, and incidence rate ratios were used to test for significant differences in infection rates. During the study period, the HHCS collected many more hand hygiene events compared with human observers (632,404 vs 480) and ensured that the hospital met its compliance goals (95%+). Although decreases in multidrug-resistant organisms, central line-associated bloodstream infections, and catheter-associated urinary tract infection rates were observed, they represented nonsignificant differences. Human hand hygiene observers may not report accurate measures of compliance. The HHCS is a promising new tool for fine-grained assessment of hand hygiene compliance. Further study is needed to examine the association between the HHCS and HAI rate reduction. Copyright © 2017 Association for Professionals in Infection Control and Epidemiology, Inc.

Full Text Available Abstract Background General Practitioners spend a disproportionate amount of time on frequent attenders. So far, trials on the effect of interventions on frequent attenders have shown negative results. However, these trials were conducted in short-term frequent attenders. It would be more reasonable to target intervention at persistent frequent attenders. Typical characteristics of persistent frequent attenders, as opposed to 1-year frequent attenders and non-frequent attenders, may generate hypotheses regarding modifiable factors on which new randomized trials may be designed. Methods We used the data of all 28,860 adult patients from 5 primary healthcare centers. Frequent attenders were patients whose attendance rate ranked in the (age and sex adjusted top 10 percent during 1 year (1-year frequent attenders or 3 years (persistent frequent attenders. All other patients on the register over the 3-year period were referred to as non-frequent attenders. The lists of medical problems coded by the GP using the International Classification of Primary Care (ICPC were used to assess morbidity. First, we determined which proportion of 1-year frequent attenders was still a frequent attender during the next two consecutive years and calculated the GPs' workload for these patients. Second, we compared morbidity and number of prescriptions for non-frequent attenders, 1-year frequent attenders and persistent frequent attenders. Results Of all 1-year frequent attenders, 15.4% became a persistent frequent attender equal to 1.6% of all patients. The 1-year frequent attenders (3,045; 10.6% were responsible for 39% of the face-to-face consultations; the 470 patients who would become persistent frequent attenders (1.6% were responsible for 8% of all consultations in 2003. Persistent frequent attenders presented more social problems, more psychiatric problems and medically unexplained physical symptoms, but also more chronic somatic diseases (especially diabetes

The Assessment of Children's Hand Skills is a new assessment that utilises a naturalistic observational method to capture children's real-life hand skill performance when engaged at various types of daily activities in everyday living contexts. The Assessment of Children's Hand Skills is designed for use with 2- to 12-year-old children with a range of disabilities or health conditions. The study aimed to investigate construct validity of the Assessment of Children's Hand Skills in Australian children. Rasch analysis was used to examine internal construct validity of the Assessment of Children's Hand Skills in a mixed sample of 53 children with disabilities (including autism spectrum disorder, developmental/genetic disorders and physical disabilities) and 85 typically developing children. External construct validity was examined by correlating with three questionnaires evaluating daily living skills and hand skills. Rasch goodness-of-fit analysis suggested that all 22 activity items and 19 of 20 hand skill items in the Assessment of Children's Hand Skills measured a single construct. The Assessment of Children's Hand Skills items were placed in a clinically meaningful hierarchy from easy to hard, and the difficulty range of the items also matched the majority of children with disabilities and typically developing preschool-aged children.

This study evaluates hand hygiene behavior of health care workers in a German university hospital stratified for treatment of special patient groups (eg, transplant patients). From 2008 to 2010, comprehensive education and training of all health care workers was implemented to improve hand hygiene compliance. Consumption rates of alcohol-based hand rub and gloves were collected and evaluated. Of the 5,647 opportunities of hand disinfection evaluated, 1,607 occurred during care for transplant patients. To our knowledge, this is the largest survey of hand hygiene compliance in special patient groups on intensive care units in a university hospital in Germany. Health care workers on surgical intensive care units showed lower hand hygiene compliance compared with health care workers on other types of intensive care units. Compliance toward hand hygiene was significantly higher on hemato-oncologic and pediatric wards. In general, hand disinfection was performed significantly more frequently after an intervention than before (P hand hygiene compliance when caring for transplant patients or other patients (odds ratio, 1.16; 95% confidence interval: 0.95-1.42). Nurse's and physician's hand hygiene compliance improved because of education. Hand hygiene compliance is not increased in the care for transplant patients (despite their predisposition for nosocomial infections) compared with other patients. Additional studies will be necessary to further investigate these findings. Copyright © 2013 Association for Professionals in Infection Control and Epidemiology, Inc. Published by Mosby, Inc.

Handwashing is difficult in settings with limited resources and water access. In primary schools within urban Kibera, Kenya, we investigated the impact of providing waterless hand sanitizer on student hand hygiene behavior. Two schools received a waterless hand sanitizer intervention, two schools received a handwashing with soap intervention, and two schools received no intervention. Hand cleaning behavior after toilet use was monitored for 2 months using structured observation. Hand cleaning after toileting was 82% at sanitizer schools (N = 2,507 toileting events), 38% at soap schools (N = 3,429), and 37% at control schools (N = 2,797). Students at sanitizer schools were 23% less likely to have observed rhinorrhea than control students (P = 0.02); reductions in student-reported gastrointestinal and respiratory illness symptoms were not statistically significant. Providing waterless hand sanitizer markedly increased student hand cleaning after toilet use, whereas the soap intervention did not. Waterless hand sanitizer may be a promising option to improve student hand cleansing behavior, particularly in schools with limited water access.

Effectiveness of a multimodal hand hygiene campaign and obstacles to success in Addis Ababa, Ethiopia

2014-01-01

Background Hand hygiene is the cornerstone of infection control and reduces rates of healthcare associated infection. There are limited data evaluating hand hygiene adherence and hand hygiene campaign effect in resource-limited settings, especially in Sub-Saharan Africa. This study assessed the impact of implementing a World Health Organization (WHO)-recommended multimodal hand hygiene campaign at a hospital in Ethiopia. Methods This study included a before-and-after assessment of health care worker (HCW) adherence with WHO hand hygiene guidelines. It was implemented in three phases: 1) baseline evaluation of hand hygiene adherence and hospital infrastructure; 2) intervention (distribution of commercial hand sanitizer and implementation of an abbreviated WHO-recommended multimodal hand hygiene campaign); and 3) post-intervention evaluation of HCW hand hygiene adherence. HCWs’ perceptions of the campaign and hand sanitizer tolerability were assessed through a survey performed in the post-intervention period. Results At baseline, hand washing materials were infrequently available, with only 20% of sinks having hand-washing materials. There was a significant increase in hand hygiene adherence among HCWs following implementation of a WHO multimodal hand hygiene program. Adherence increased from 2.1% at baseline (21 hand hygiene actions/1000 opportunities for hand hygiene) to 12.7% (127 hand hygiene actions /1000 opportunities for hand hygiene) after the implementation of the hand hygiene campaign (OR = 6.8, 95% CI 4.2-10.9). Hand hygiene rates significantly increased among all HCW types except attending physicians. Independent predictors of HCW hand hygiene compliance included performing hand hygiene in the post-intervention period (aOR = 5.7, 95% CI 3.5-9.3), in the emergency department (aOR = 4.9, 95% CI 2.8-8.6), during patient care that did not involve Attending Physician Rounds (aOR = 2.4, 95% CI 1.2-4.5), and after patient contact (aOR = 2

Whereas several studies have examined the association between frequent attendance in primary care and illness-specific psychological factors, little is known about the relation between frequent attendance and general psychological factors. Thus, the aim of this study was to investigate the association between being a frequent attender in primary care and general psychological factors. Data were used from a large, population-based sample of community-dwelling individuals aged 40 and above in Germany in 2014 (n = 7,446). Positive and negative affect, life satisfaction, optimism, self-esteem, self-efficacy, and self-regulation were included as general psychological factors. The number of self-reported GP visits in the past twelve months was used to quantify frequency of attendance; individuals with more than 9 visits (highest decile) were defined as frequent attenders. Multiple logistic regressions showed that being a frequent attender was positively associated with less life satisfaction [OR: 0.79 (0.70-0.89)], higher negative affect [OR: 1.38 (1.17-1.62)], less self-efficacy [OR: 0.74 (0.63-0.86)], less self-esteem [OR: 0.65 (0.54-0.79)], less self-regulation [OR: 0.74 (0.60-0.91)], and higher perceived stress [OR: 1.46 (1.28-1.66)], after adjusting for sociodemographic factors, morbidity and lifestyle factors. However, frequent attendance was not significantly associated with positive affect and self-regulation. The present study highlights the association between general psychological factors and frequent attendance. As frequent GP visits produce high health care costs and are potentially associated with increased referrals and use of secondary health care services, this knowledge might help to address these individuals with high needs.

Despite the importance of hand hygiene in the health care setting, there are no studies evaluating hand hygiene compliance at hospital entrances. The study was prospectively performed over a 33-week period from March 30, 2014-November 15, 2014, to evaluate hand hygiene compliance in 2 hospital reception areas. We compared electronic handwash counters with the application of radiofrequency identification (GOJO SMARTLINK) (electronic observer) that counts each activation of alcohol gel dispensers to direct observation (human observer) via remote review of video surveillance. We found low hand hygiene compliance rates of 2.2% (99/4,412) and 1.7% (140/8,277), respectively, at reception areas A and D, detected by direct observation. Using the electronic observer, we measured rates of 17% (15,624/91,724) and 7.1% (51,605/730,357) at reception areas A and D, respectively. For the overall time period of simultaneous electronic and human observation, the human observer captured 1% of the hand hygiene episodes detected by the electronic observer. Our study showed very low hand hygiene compliance in hospital reception areas, and we found an electronic hand hygiene system to be a useful method to monitor hand hygiene compliance.

Critical hand ischemia (CHI) can be devastating and may result in amputation. Distal vessel calcification has been shown to be a major factor in causing CHI. Atherectomy in the upper extremities is not typically considered due to the small anatomy; however, the Diamondback 360° Peripheral Orbital Atherectomy System (OAS) (Cardiovascular Systems, Inc.) can access treatment areas with a reference vessel diameter of 1.5mm. A retrospective, observational, single center (Merit Health Center, Jackson, MS) analysis of 11 CHI patients with calcific disease of the radial artery treated with orbital atherectomy (OAS) was completed. Demographics and procedural to 30-day outcomes were assessed. All patients had good blood flow to the hand after intervention and none experienced complications during or immediately post-procedure. At 30-days the freedom from revascularization and amputation was 100%, and all the wounds were healed. The following important principles were followed during the use of OAS for CHI: (1) ACT was therapeutic (~250s); (2) Gentle wire manipulation; (3) Utilization of a small OAS crown (1.25mm); (4) Aggressive vasodilator use-given through the exchange catheter; (5) Angioplasty balloon was matched to the size of the vessel and long and low pressure inflations were completed. Critical hand ischemia can be treated with endovascular techniques. Obtaining good outflow to the fingers is critical for wound healing and preventing amputation. Orbital atherectomy is a useful tool in preparing vessels for balloon angioplasty; particularly in cases where calcification is present. Copyright © 2016 The Authors. Published by Elsevier Inc.

Efforts to formalise the role of traditional birth attendants (TBAs) in maternal and neonatal health programmes have had limited success. TBAs' continued attendance at home deliveries suggests the potential to influence maternal and neonatal outcomes. The objective of this qualitative study was to identify and understand the knowledge, attitudes and practices of TBAs in rural Nepal. Twenty-one trained and untrained TBAs participated in focus groups and in-depth interviews about antenatal care, delivery practices, maternal complications and newborn care. Antenatal care included advice about nutrition and tetanus toxoid (TT) immunisation, but did not include planning ahead for transport in cases of complications. Clean delivery practices were observed by most TBAs, though hand-washing practices differed by training status. There was no standard practice to identify maternal complications, such as excessive bleeding, prolonged labour, or retained placenta, and most referred outside in the event of such complications. Newborn care practices included breastfeeding with supplemental feeds, thermal care after bathing, and mustard seed oil massage. TBAs reported high job satisfaction and desire to improve their skills. Despite uncertainty regarding the role of TBAs to manage maternal complications, TBAs may be strategically placed to make potential contributions to newborn survival.

Handwashing is difficult in settings with limited resources and water access. In primary schools within urban Kibera, Kenya, we investigated the impact of providing waterless hand sanitizer on student hand hygiene behavior. Two schools received a waterless hand sanitizer intervention, two schools received a handwashing with soap intervention, and two schools received no intervention. Hand cleaning behavior after toilet use was monitored for 2 months using structured observation. Hand cleaning after toileting was 82% at sanitizer schools (N = 2,507 toileting events), 38% at soap schools (N = 3,429), and 37% at control schools (N = 2,797). Students at sanitizer schools were 23% less likely to have observed rhinorrhea than control students (P = 0.02); reductions in student-reported gastrointestinal and respiratory illness symptoms were not statistically significant. Providing waterless hand sanitizer markedly increased student hand cleaning after toilet use, whereas the soap intervention did not. Waterless hand sanitizer may be a promising option to improve student hand cleansing behavior, particularly in schools with limited water access. PMID:23836575

Healthcare facility hand hygiene impacts patient care, healthcare worker safety, and infection control, but low-income countries have few data to guide interventions. To conduct a nationally representative survey of hand hygiene infrastructure and behaviour in Bangladeshi healthcare facilities to establish baseline data to aid policy. The 2013 Bangladesh National Hygiene Baseline Survey examined water, sanitation, and hand hygiene across households, schools, restaurants and food vendors, traditional birth attendants, and healthcare facilities. We used probability proportional to size sampling to select 100 rural and urban population clusters, and then surveyed hand hygiene infrastructure in 875 inpatient healthcare facilities, observing behaviour in 100 facilities. More than 96% of facilities had 'improved' water sources, but environmental contamination occurred frequently around water sources. Soap was available at 78-92% of handwashing locations for doctors and nurses, but just 4-30% for patients and family. Only 2% of 4676 hand hygiene opportunities resulted in recommended actions: using alcohol sanitizer or washing both hands with soap, then drying by air or clean cloth. Healthcare workers performed recommended hand hygiene in 9% of 919 opportunities: more after patient contact (26%) than before (11%). Family caregivers frequently washed hands with only water (48% of 2751 opportunities), but with little soap (3%). Healthcare workers had more access to hand hygiene materials and performed better hand hygiene than family, but still had low adherence. Increasing hand hygiene materials and behaviour could improve infection control in Bangladeshi healthcare facilities. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

An observational study was conducted to evaluate hygiene habits of students with fields of study, gender, and understanding of hygiene at a university in Alabama. One hundred students were randomly observed in ten restrooms on campus to determine whether or not students washed their hands. The study was divided into an observational stage, a quiz to ascertain student's knowledge of hygiene and the spread of pathogens, and a survey of self-reported illness rates. Females had a tendency to wash their hands more often than males while visiting the bathroom (p = 0.02, chi2 = 11.6). Science majors were more likely to wash their hands than non-science majors (p < or = 0.001, chi2 = 5.2). Females (p < or = 0.0001, df = 98, F = 21.5) and science majors (p < or = 0.0001, df = 98, F = 81.4) scored significantly higher on the survey than males and nonscience majors, and that those observed not washing their hands reported being sick more often than those observed washing their hands (chi2 = 155.0, df= 3, p < 0.001, Fisher's exact p < 0.001).

Full Text Available The childhood epilepsy is a chronic disease that can have an impact in various spheres of life of the child, including academic performance and school attendance. This study aimed to describe and compare the school attendance of children with epilepsy who attend mainstream and special schools. Participants were 56 children aged between 7 and 14 years who attended regular or special schools located in two Brazilian cities of medium size. To collect the information we used two instruments: Data sheet of identification and characterization of the child and Data sheet to record the attendance school. The results showed that children in special schools had higher rates of absenteeism compared to students in regular schools. Additionally, we observed that these children use more drugs and have implications on health more severe than children in regular schools. Thus, it is the childhood epilepsy as a disease complex that brings substantial effects on various areas of children’s lives by reinforcing the need for studies that might expand the knowledge to and the experiences associated with the education of these children.

Epidemiologic transition is taking place in every part of the world. Cardiovascular diseases became the most common cause of death accounting for 30% of deaths worldwide, with 80% of the burden now occurring in developing countries. The objective of the study was to assess the Pattern of disease among patients attending Cardiology outpatient department of a private hospital. The cross sectional descriptive type of observational study was conducted among 550 patients attending Cardiology outpatient department (COPD) of Sodesh Hospital, Mymensingh, Bangladesh from March 2016 to June 2016. All the new patients attending COPD of Sodesh Hospital were selected purposively for the study. Data were collected by interview, physical examination and laboratory investigations of patients using a case record form. Mean age of the patients was 45.1 years with a SD of 15.6 years. Among the patients male were 291(52.9%), a bit higher than the female 259(47.1%). It was observed that more than half of the patients (281, 51.1%) visited cardiologist with non-cardiac problems. Less than one third of the patients (169, 30.7%) attended with cardiac problems and 100(18.2%) patients visited with both cardiac and non-cardiac problems. Among the cardiac diseases and symptoms hypertension was on the top of the list 176(65.4%). Ischemic heart diseases was present in 35(13.0%) and palpitation was in 30(11.1%) patients. On the other hand among the non-cardiac diseases or presentations, 121(43.1%) patients had non-specific chest pain, 63(22.4%) had shortness of breath and 17(6.1%) had diabetes mellitus. Hypertension was found the most frequent cardiovascular disease (65.4%) followed by ischemic heart disease (13.0%). More than half (51.1%) of the patients visit cardiologist with non-cardiac problems. Screening at the level of general practitioner (GP) and appropriate referral system can reduce extreme burden of patients to the cardiologists in the Cardiology outpatient department.

Boosting the Motor Outcome of the Untrained Hand by Action Observation: Mirror Visual Feedback, Video Therapy, or Both Combined—What Is More Effective?

Directory of Open Access Journals (Sweden)

Florian Bähr

2018-01-01

Full Text Available Action observation (AO allows access to a network that processes visuomotor and sensorimotor inputs and is believed to be involved in observational learning of motor skills. We conducted three consecutive experiments to examine the boosting effect of AO on the motor outcome of the untrained hand by either mirror visual feedback (MVF, video therapy (VT, or a combination of both. In the first experiment, healthy participants trained either with MVF or without mirror feedback while in the second experiment, participants either trained with VT or observed animal videos. In the third experiment, participants first observed video clips that were followed by either training with MVF or training without mirror feedback. The outcomes for the untrained hand were quantified by scores from five motor tasks. The results demonstrated that MVF and VT significantly increase the motor performance of the untrained hand by the use of AO. We found that MVF was the most effective approach to increase the performance of the target effector. On the contrary, the combination of MVF and VT turns out to be less effective looking from clinical perspective. The gathered results suggest that action-related motor competence with the untrained hand is acquired by both mirror-based and video-based AO.

This study assessed the potential therapeutic benefi t of using HandTutor™ in combination with traditional rehabilitation in a post-stroke sub-acute population. The study compares an experimental group receiving traditional therapy combined with HandTutorTM treatment, against a control group receiving only traditional therapy. An assessor-blinded, randomized controlled pilot trial, was conducted in the Reuth rehabilitation unit in Israel. Thirty-one stroke patients in the sub-acute phase, were randomly assigned to one of the two groups (experimental or control) in sets of three. The experimental group (n = 16) underwent a hand rehabilitation programme using the HandTutorTM combined with traditional therapy. The control group (n = 15) received only traditional therapy. The treatment schedules for both groups were of similar duration and frequency. Improvements were evaluated using three indicators: 1) The Brunnström-Fugl-Meyer (FM) test, 2) the Box and Blocks (B&B) test and 3) improvement parameters as determined by the HandTutorTM software. Following 15 consecutive treatment sessions, a signifi cant improvement was observed within the experimental group (95% confi dence intervals) compared with the control group: B&B p = 0.015; FM p = 0.041, HandTutor™ performance accuracy on x axis and performance accuracy on y axis p stroke hand function rehabilitation.

The coordination patterns observed when two hands reach-to-grasp separate objects.

Bingham, Geoffrey P; Hughes, Kirstie; Mon-Williams, Mark

What determines coordination patterns when both hands reach to grasp separate objects at the same time? It is known that synchronous timing is preferred as the most stable mode of bimanual coordination. Nonetheless, normal unimanual prehension behaviour predicts asynchrony when the two hands reach towards unequal targets, with synchrony restricted to targets equal in size and distance. Additionally, sufficiently separated targets require sequential looking. Does synchrony occur in all cases because it is preferred in bimanual coordination or does asynchrony occur because of unimanual task constraints and the need for sequential looking? We investigated coordinative timing when participants (n = 8) moved their right (preferred) hand to the same object at a fixed distance but the left hand to objects of different width (3, 5, and 7 cm) and grip surface size (1, 2, and 3 cm) placed at different distances (20, 30, and 40 cm) over 270 randomised trials. The hand movements consisted of two components: (1) an initial component (IC) during which the hand reached towards the target while forming an appropriate grip aperture, stopping at (but not touching) the object; (2) a completion component (CC) during which the finger and thumb closed on the target. The two limbs started the IC together but did not interact until the deceleration phase when evidence of synchronisation began to appear. Nonetheless, asynchronous timing was present at the end of the IC and preserved through the CC even with equidistant targets. Thus, there was synchrony but requirements for visual information ultimately yielded asynchronous coordinative timing.

The aim of the first part of this work is to assess the attendance in the early detection (mammography) in female employees of Warsaw-based higher schools aged 40-69. During the 4.5 year period (1985-1989) 1325 female employees of higher schools (23.5% of the schools' total employment) turned up to the Female Cancer Prevention Center of The Higher Schools' Medical Center (ZOZ) in Warsaw. Observation of this group continued until June 30, 1992. Majority of the women (56.5%) showed up only once, 21.7% came twice, and 21.8% at least three times. Out of the 1021 women (77% of all the examined female employees) who showed no symptoms in the first test, only 37% came again for the second checkup. Out of the 305 women who had changes detected in their X-ray images, 66% turned up for the second test. 23 women (1.7%) had suspicious mammography results or typical cancer symptoms in the first test. The present work shows that the reason of the insufficient attendance of higher schools' female employees in early detection programs need to be investigated and that a more efficient early detection system must be developed.

Beyond folding and gathering: museums attending to the new materiality

Directory of Open Access Journals (Sweden)

Kylie Budge

2017-06-01

Full Text Available Museums are attending to matters of technique in relation to objects and exhibitions suggesting a new or renewed interest in creative practice and how objects are made. This focus parallels practices and changes occurring in broader society. In this article I argue that a rise in attending to technique extends what various theorists have referred to as the ‘material turn’ in a dimension that underscores creative process and making. I do so by exploring two recent exhibitions, one in Israel and another in Australia, which have brought the notion of technique into focus through the context of textiles and other materials such as paper, porcelain, wood and metal. Through their emphasis on ‘gathering’ and ‘folding’, the construction of textiles and other forms are accentuated for public exploration, fostering new understandings of technique. Conclusions are drawn connecting museum contexts with that of broader society in reference to making, the role of the hand, and craft processes.

Intravenous drug addiction is responsible for many complications, especially cutaneous and infectious. There is a syndrome, rarely observed in rheumatology, resulting in "puffy hands": the puffy hand syndrome. We report two cases of this condition from our rheumatologic consultation. Our two patients had intravenous drug addiction. They presented with an edema of the hands, bilateral, painless, no pitting, occurring in one of our patient during heroin intoxication, and in the other 2 years after stopping injections. In our two patients, additional investigations (biological, radiological, ultrasound) were unremarkable, which helped us, in the context, to put the diagnosis of puffy hand syndrome. The pathophysiology, still unclear, is based in part on a lymphatic toxicity of drugs and their excipients. There is no etiological treatment but elastic compression by night has improved edema of the hands in one of our patients. Copyright © 2016 Société française de rhumatologie.

We analyze the changes observed between 1996 and 2001 in the distribution of the pathology attended and the follow up model used by the out-patient Neurology Clinic in the Marina Alta area, in order to confirm possible variations that may have repercussions for Human Resource needs in the provision of adequate neurological care. We prospectively registered the attendance records for visits made to the Out-patient Neurology Clinic of Marina Alta in 1996. The variation coefficients between both series were calculated and compared. The average age of patients increased in 5 years. The number of patients attended increased 42.3%, new patients 40%, visits 13%, the "Review visit/First Visit" ratio reduced 29%. The attendance of patients with Cognitive Impairment (Cog. Imp.) doubled. There were no changes in the origins of the patients. Requests due to Cog. Imp. and parkinsonism increased significantly from Primary Care and Emergency Department. The delay to be attended increased 23%. Discharges increased 43.9%, highlighting an increase of 144% observed in the Cog. Imp. group. Changes have been observed in: the age of the population studied; the follow up of patients; the delay in attending them; and the pathology attended, with a significant increase in demand due to neurodegenerative pathology (especially Cog. Imp.). All this requires an increase in care needs that the Health Service has not been able to assume, creating an incongruous care model: we suggest a direct follow up model and offer a consultancy model.

Forrester, L A; Bryce, E A; Mediaa, A K

2010-03-01

A year-long multifaceted hand-hygiene campaign entitled Clean Hands for Life targeting individual, environmental and organisational factors that influence healthcare worker (HCW) hand-hygiene behaviour was implemented in 36 acute and long-term care facilities in Vancouver Coastal Health region. The campaign involved rotation of ten novel posters, two poster contests, and distribution of multiple promotional items. A social marketing approach was used to implement and monitor the effectiveness of the campaign. Evaluation included quality assurance surveys, staff surveys (baseline, mid- and post-campaign), and focus groups. A total of 141 poster contest submissions was received, 5452 staff surveys completed and 14 focus groups conducted. Overall knowledge of the importance of hand-hygiene and intention to clean hands was high at baseline. No significant differences were observed when mid- and post-campaign scores were compared to baseline. The majority (89.5%) of HCWs reported that they preferred soap and water over alcohol hand gel. A significant increase in the self-reported use of hand-hygiene products was observed particularly among HCWs not providing direct patient care. Barriers to hand-hygiene included inappropriate placement of sinks, traffic flow issues, inadequately stocked washrooms, workload and time constraints. Organisational support was visible throughout the campaign. The results showed that social marketing is an effective approach in engaging HCWs. Hand-hygiene campaigns that focus almost exclusively on increasing awareness among HCWs may not be as successful as multifaceted campaigns or campaigns that target identified barriers to hand-hygiene.

2011-03-01

In patient studies, impairments of sense of body ownership have repeatedly been linked to right-hemispheric brain damage. To test whether a right-hemispheric dominance for sense of body ownership could also be observed in healthy adults, the rubber hand illusion was elicited on both hands of 21 left-handers and 22 right-handers. In this illusion, a participant's real hand is stroked while hidden from view behind an occluder, and a nearby visible hand prosthesis is repeatedly stroked in synchrony. Most participants experience the illusionary perception of touch sensations arising from the prosthesis. The vividness of the illusion was measured by subjective self-reports as well as by skin conductance responses to watching the rubber hand being harmed. Handedness did not affect the vividness of the illusion, but a stronger skin conductance response was observed, when the illusion was elicited on the left hand. These findings suggest a right-hemispheric dominance for sense of body ownership in healthy adults.

Prolonged disengagement from distractors near the hands

Directory of Open Access Journals (Sweden)

Daniel B Vatterott

2013-08-01

Full Text Available Because items near our hands are often more important than items far from our hands, the brain processes visual items near our hands differently than items far from our hands. Multiple experiments have attributed this processing difference to spatial attention, but the exact mechanism behind how spatial attention near our hands changes is still under investigation. The current experiments sought to differentiate between two of the proposed mechanisms: a prioritization of the space near the hands and a prolonged disengagement of spatial attention near the hands. To differentiate between these two accounts, we used the additional singleton paradigm in which observers searched for a shape singleton among homogenously shaped distractors. On half the trials, one of the distractors was a different color. Both the prioritization and disengagement accounts predict differently colored distractors near the hands will slow target responses more than differently colored distractors far from the hands, but the prioritization account also predicts faster responses to targets near the hands than far from the hands. The disengagement account does not make this prediction, because attention does not need to be disengaged when the target appears near the hand. We found support for the disengagement account: Salient distractors near the hands slowed responses more than those far from the hands, yet observers did not respond faster to targets near the hands.

Use of a machine learning algorithm to classify expertise: analysis of hand motion patterns during a simulated surgical task.

Watson, Robert A

2014-08-01

To test the hypothesis that machine learning algorithms increase the predictive power to classify surgical expertise using surgeons' hand motion patterns. In 2012 at the University of North Carolina at Chapel Hill, 14 surgical attendings and 10 first- and second-year surgical residents each performed two bench model venous anastomoses. During the simulated tasks, the participants wore an inertial measurement unit on the dorsum of their dominant (right) hand to capture their hand motion patterns. The pattern from each bench model task performed was preprocessed into a symbolic time series and labeled as expert (attending) or novice (resident). The labeled hand motion patterns were processed and used to train a Support Vector Machine (SVM) classification algorithm. The trained algorithm was then tested for discriminative/predictive power against unlabeled (blinded) hand motion patterns from tasks not used in the training. The Lempel-Ziv (LZ) complexity metric was also measured from each hand motion pattern, with an optimal threshold calculated to separately classify the patterns. The LZ metric classified unlabeled (blinded) hand motion patterns into expert and novice groups with an accuracy of 70% (sensitivity 64%, specificity 80%). The SVM algorithm had an accuracy of 83% (sensitivity 86%, specificity 80%). The results confirmed the hypothesis. The SVM algorithm increased the predictive power to classify blinded surgical hand motion patterns into expert versus novice groups. With further development, the system used in this study could become a viable tool for low-cost, objective assessment of procedural proficiency in a competency-based curriculum.

Low-dose computed tomography (LDCT) techniques can reduce exposure to radiation. Several previous studies have shown that radiation dose reduction in LDCT does not decrease the diagnostic performance for appendicitis among attending radiologists. But, the LDCT diagnostic performance for acute appendicitis in radiology residents with variable training levels has not been well discussed. To compare inter-observer and intra-observer differences of diagnostic performance on non-enhanced LDCT (NE-LDCT) and contrast-enhanced standard dose CT (CE-SDCT) for acute appendicitis among attending and resident radiologists. This retrospective study included 101 patients with suspected acute appendicitis who underwent NE-LDCT and CE-SDCT. The CT examinations were interpreted and recorded on a five-point scale independently by three attending radiologists and three residents with 4, 1 and 1 years of training. Diagnostic performance for acute appendicitis of all readers on both examinations was represented by area under receiver operating characteristic (ROC) curves. Inter-observer and intra-observer AUC values were compared using Jackknife FROC software on both modalities. The diagnostic accuracy of each reader on NE-LDCT was compared with body mass index (BMI) subgroups and noise using independent T test. Diagnostic performances for acute appendicitis were not statistically different for attending radiologists at both examinations. Better performance was noted on the CE-SDCT with a borderline significant difference (P = 0.05) for senior radiology resident. No statistical difference of AUC values was observed between attending radiologists and fourth year resident on both examinations. Statistically signifi@@cant differences of AUC values were observed between attending radiologists and first year residents (P = 0.001 ~ 0.018) on NE-LDCT. Diagnostic accuracies of acute appendicitis on NE-LDCT for each reader were not significantly related to BMI or noise. Attending radiologists

Professional ethics in extreme circumstances: responsibilities of attending physicians and healthcare providers in hunger strikes.

Science.gov (United States)

Irmak, Nurbay

2015-08-01

Hunger strikes potentially present a serious challenge for attending physicians. Though rare, in certain cases, a conflict can occur between the obligations of beneficence and autonomy. On the one hand, physicians have a duty to preserve life, which entails intervening in a hunger strike before the hunger striker loses his life. On the other hand, physicians' duty to respect autonomy implies that attending physicians have to respect hunger strikers' decisions to refuse nutrition. International medical guidelines state that physicians should follow the strikers' unpressured advance directives. When physicians encounter an unconscious striker, in the absence of reliable advance directives, the guidelines advise physicians to make a decision on the basis of the patient's values, previously expressed wishes, and best interests. I argue that if there are no advance directives and the striker has already lost his competence, the physician has the responsibility to resuscitate the striker. Once the striker regains his decision-making capacity, he should be asked about his decision. If he is determined to continue fasting and refuses treatment, the physician has a moral obligation to respect this decisions and follow his advance directives.

Using Attendance Worksheets to Improve Student Attendance, Participation, and Learning

As science instructors we are faced with two main barriers with respect to student learning. The first is motivating our students to attend class and the second is to make them active participants in the learning process once we have gotten them to class. As we head further into the internet age this problem only gets exacerbated as students have replaced newspapers with cell phones which can surf the web, check their emails, and play games. Quizzes can motivated the students to attend class but do not necessarily motivate them to pay attention. Active learning techniques work but we as instructors have been bombarded by the active learning message to the point that we either do it already or refuse to. I present another option which in my classroom has doubled the rate at which students learn my material. By using attendance worksheets instead of end of class quizzes I hold students accountable for not just their attendance but for when they show up and when they leave the class. In addition it makes the students an active participant in the class even without using active learning techniques as they are writing notes and answering the questions you have posed while the class is in progress. Therefore using attendance worksheets is an effective tool to use in order to guide student learning.

Full Text Available Background: Hand eczema is a common distressing condition aggravated by a number of endogenous and exogenous factors. Various morphological forms of hand eczema have been described, but categorization into one of them is not always possible. Aims: To study the morphological patterns of hand eczema, relationship of atopy with hand eczema, and the implications of contact sensitization with respect to severity and diagnosis of hand eczema. Methods: Hundred consecutive patients of hand eczema attending the contact dermatitis clinic of the institute were recruited over a two year period from 2004-05. Objective assessment was done using hand eczema severity index (HECSI and all the patients were patch tested using Indian standard series. Results: Unspecified type of hand eczema with no definite morphologic picture was seen in 62% followed by pompholyx in 14%. Hand eczema severity was not found to be statistically associated with age, sex, and atopic status of the patient. Positive patch test to one or more allergen was present in 65% of patients. The most common allergens were potassium dichromate (25%, fragrance mix (16%, nickel sulphate (14%, and PPD (13%. There was no significant correlation between patch test positivity and hand eczema severity or atopic status of the patient. Among the morphological patterns pompholyx was strongly associated with an atopic status (P=0.004. Conclusions: Hand eczema was seen twice more commonly in men. Atopic and non-atopic patients of hand eczema had no difference in the severity of disease. Contact sensitivity to different allergens did not correlate with increased eczema severity.

Electrophysiological and psychophysical data indicate that grasping observation automatically orients attention toward the incoming interactions between the actor's hand and the object. The aim of the present study was to clarify if this effect facilitates the detection of a graspable object with the observed action as compared to an ungraspable one. We submitted participants to an object-identity probability cueing experiment in which the two possible targets were of the same dimensions but one of them presented sharp tips at one extreme while the other presented flat faces. At the beginning of each trial the most probable target was briefly shown. After a variable interval, at the same position, the same (75%) or a different target (25%) was presented. Participants had to press a key in response to target appearance. Superimposed to the video showing cue and target, an agent performing the reaching and grasping of the target was presented. The kinematics of the action was or was not suitable for grasping the cued target, according to the absence or presence of the sharp tips. Results showed that response was modulated by the probability of target identity but only when the observed kinematics was suitable to grasp the attended target. A further experiment clarified that response modulation was never present when the superimposed video always showed the agent at a rest position. These findings are discussed at the light of neurophysiological and psychophysical literature, considering the relationship between the motor system and the perception of objects and of others' actions. We conclude that the prediction of the mechanical events that arise from the interactions between the hand and the attended object is at the basis of the capability to select a graspable object in space.

Full Text Available This research involves an android application in attendance management system. The study sought to provide an alternative solution to the increasing demand for time management in the College of Engineering and Computing Sciences in Batangas State University ARASOF. Through the said Android application the attendance checking will be much easier, for it will reduce the roll call that takes a lot of time. It was developed to help the lecturers have sufficient time for teaching and the students for learning. The researchers used research design, development process, and programming procedures in their study. The “Attendroid”, was designed and develop using Eclipse, Java Script, Php and HTML. This application is for android phones and tablet which has portable hotspot. The android application for the students will run on 2.2versions of android and higher. The android application has gone through an evaluation to test whether the system is acceptable in terms of security, accuracy, reliability, maintainability and user-friendliness against the manual checking of attendance. The result shows that the respondents are more favorable in the Attendroid because it can be gleaned that they gave an excellent feedback to the application compared to the manual process of attendance checking. After thorough study of the old ways of attendance checking against the newly developed application, a necessity to improve the manual checking was observed, and therefore, strengthen the advantages of implementing Attendroid. Based on the result of the proposed users’ acceptability, Attendroid could become the formal attendance checking system of the College of Engineering and Computing Sciences.

The left hand doesn't know what the right hand is doing: the disruptive effects of attention to the hands in skilled typewriting.

Science.gov (United States)

Logan, Gordon D; Crump, Matthew J C

2009-10-01

Everyone knows that attention to the details disrupts skilled performance, but little empirical evidence documents this fact. We show that attention to the hands disrupts skilled typewriting. We had skilled typists type words preceded by cues that told them to type only the letters assigned to one hand or to type all of the letters. Cuing the hands disrupted performance markedly, slowing typing and increasing the error rate (Experiment 1); these deleterious effects were observed even when no keystrokes were actually inhibited (Experiment 3). However, cuing the same letters with colors was not disruptive (Experiment 2). We account for the disruption with a hierarchical control model, in which an inner loop controls the hands and an outer loop controls what is typed. Typing letters using only one hand requires the outer loop to monitor the inner loop's output; the outer loop slows inner-loop cycle time to increase the likelihood of inhibiting responses with the unwanted hand. This produces the disruption.

The aim of this study was to assess attendance at the universal screening programme for thyroid function in pregnancy and attempt to evaluate the influence of age, number of past pregnancies, level of education, and place of residence on the attendance. The study was performed by means of a questionnaire. Our study was performed on the basis of an anonymous questionnaire handed out to 543 women aged 16-45 years, on the third day of their puerperal stay in one of five obstetric wards in southern Poland. The questionnaire contained questions about participation in plasma level measurements of TSH, fT4, total T4, thyroid antibodies or thyroid ultrasound scanning at least once in pregnancy. The rate of attendance at any examination of thyroid function among pregnant women was 26.7%. The highest attendance rate (32.7%) was found among women living in provincial capitals or with higher education (41.3%), whereas the lowest was among women who had completed only primary school (11%) and those living in county towns (15%). The number of previous pregnancies did not influence the thyroid screening attendance. Women over 21 years of age participated in this screening programme more frequently (27.1-30%). Less than one third of pregnant women participated in the thyroid function screening. Place of living, education level, and age were the main factors influencing the attendance rate.

Child-care attendance and common morbidity: evidence of association in the literature and questions of design

Full Text Available Papers on child-care attendance as a risk factor for acute respiratory infections and diarrhea were reviewed. There was great variety among the studies with regard to the design, definition of exposure and definition of outcomes. All the traditional epidemiological study designs have been used. The studies varied in terms of how child-care attendance in general was defined, and for different settings. These definitions differed especially in relation to the minimum time of attendance required. The outcomes were also defined and measured in several different ways. The analyses performed were not always appropriate, leading to sets of results of uneven quality, and composed of different measures of association relating different exposures and outcomes, that made summarizing difficult. Despite that, the results reported were remarkably consistent. Only two of the papers reviewed failed to show some association between child-care attendance and increased acute respiratory infections, or diarrhea. On the other hand, the magnitude of the associations reported varied widely, especially for lower respiratory infections. Taken together, the studies so far published provide evidence that children attending child-care centers, especially those under three years of age, are at a higher risk of upper respiratory infections, lower respiratory infections, and diarrhea. The studies were not consistent, however, in relation to attendance at child-care homes. Children in such settings were sometimes similar to those in child-care centers, sometimes similar to those cared for at home, and sometimes presented an intermediate risk.

A person-oriented approach to hand hygiene behaviour: Emotional empathy fosters hand hygiene practice.

2016-01-01

Adopting a social-psychological approach, this research examines whether emotional empathy, an affective reaction regarding another's well-being, fosters hand hygiene as this affects other's health-related well-being extensively. Three studies tested this notion: (a) a cross-sectional study involving a sample of health care workers at a German hospital, (b) an experiment testing the causal effect of empathy on hand hygiene behaviour and (c) an 11-week prospective study testing whether an empathy induction affected disinfectant usage frequency in two different wards of a hospital. Self-reported hand hygiene behaviour based on day reconstruction method was measured in Study 1, actual hand sanitation behaviour was observed in Study 2 and disinfectant usage frequency in two different hospital wards was assessed in Study 3. Study 1 reveals an association of empathy with hand hygiene cross-sectionally, Study 2 documents the causal effect of empathy on increased hand sanitation. Study 3 shows an empathy induction increases hand sanitiser usage in the hospital. Increasing emotional empathy promotes hand hygiene behaviour, also in hospitals. Besides providing new impulses for the design of effective interventions, these findings bear theoretical significance as they document the explanatory power of empathy regarding a distal explanandum (hand hygiene).

Comparative study of presurgical hand hygiene with hydroalcoholic solution versus traditional presurgical hand hygiene.

López Martín, M Beatriz; Erice Calvo-Sotelo, Alejo

To compare presurgical hand hygiene with hydroalcoholic solution following the WHO protocol with traditional presurgical hand hygiene. Cultures of the hands of surgeons and surgical nurses were performed before and after presurgical hand hygiene and after removing gloves at the end of surgery. Cultures were done in 2different days: the first day after traditional presurgical hand hygiene, and the second day after presurgical hand hygiene with hydroalcoholic solution following the WHO protocol. The duration of the traditional hand hygiene was measured and compared with the duration (3min) of the WHO protocol. The cost of the products used in the traditional technique was compared with the cost of the hydroalcoholic solution used. The variability of the traditional technique was determined by observation. Following presurgical hand hygiene with hydroalcoholic solution, colony-forming units (CFU) were detected in 5 (7.3%) subjects, whereas after traditional presurgical hand hygiene CFU were detected in 14 subjects (20.5%) (p < 0.05). After glove removal, the numbers of CFU were similar. The time employed in hand hygiene with hydroalcoholic solution (3min) was inferior to the time employed in the traditional technique (p < 0.05), its cost was less than half, and there was no variability. Compared with other techniques, presurgical hand hygiene with hydroalcoholic solution significantly decreases CFU, has similar latency time, a lower cost, and saves time.

Patient hand-offs involve the exchange of critical information. Ineffective hand-offs can result in reduced patient safety by leading to wrong treatment, delayed diagnoses or other outcomes that can negatively affect the healthcare system. The objectives of this study were to uncover the structure of the information conveyed during patient hand-offs and look for principles characterising the organisation of the information. With an observational study approach, data was gathered during the morning and evening nursing change of shift hand-offs in a Paediatric Intensive Care Unit. Content analysis identified a common meta-structure used for information transfer that contained categories with varying degrees of information integration and the repetition of high consequence information. Differences were found in the organisation of the hand-off structures, and these varied as a function of nursing experience. The findings are discussed in terms of the potential benefits of computerised tools which utilise standardised structure for information transfer and the implications for future education and critical care skill acquisition.

From self-observation to imitation: visuomotor association on a robotic hand.

Chaminade, Thierry; Oztop, Erhan; Cheng, Gordon; Kawato, Mitsuo

Being at the crux of human cognition and behaviour, imitation has become the target of investigations ranging from experimental psychology and neurophysiology to computational sciences and robotics. It is often assumed that the imitation is innate, but it has more recently been argued, both theoretically and experimentally, that basic forms of imitation could emerge as a result of self-observation. Here, we tested this proposal on a realistic experimental platform, comprising an associative network linking a 16 degrees of freedom robotic hand and a simple visual system. We report that this minimal visuomotor association is sufficient to bootstrap basic imitation. Our results indicate that crucial features of human imitation, such as generalization to new actions, may emerge from a connectionist associative network. Therefore, we suggest that a behaviour as complex as imitation could be, at the neuronal level, founded on basic mechanisms of associative learning, a notion supported by a recent proposal on the developmental origin of mirror neurons. Our approach can be applied to the development of realistic cognitive architectures for humanoid robots as well as to shed new light on the cognitive processes at play in early human cognitive development.

Within the Australian public health care system, an observation model is used to assess hand hygiene practice in health care workers, culminating in a publicly available healthcare service performance indicator. The intent of this study was for the results to inform the development of a strategy to support individual auditors and local sustainability of the hand hygiene auditing program. This qualitative study used a values clarification tool to gain an understanding of the experiences of hand hygiene auditors. The methodology involved qualitative interpretation of focus group discussions to identify the enablers and barriers to successful performance of the auditors' role. Twenty-five participants identified congruous themes of the need for peer and managerial support, improved communication and feedback, and consideration for succession planning. There was consistency in the participants' most frequently identified significant barriers in undertaking the role. Hand hygiene auditors take pride in their role and work toward the goal of reducing health care-associated infections by having a part to play in improving hand hygiene practices of all staff members. Important themes, barriers, and enablers were identified in this study. This research will be of interest nationally and globally, considering the dearth of published information on the experience of hand hygiene auditors. This study provides evidence of the need to support individual hand hygiene auditors. Crown Copyright © 2015. Published by Elsevier Inc. All rights reserved.

Few attempts to increase healthcare workers' hand hygiene compliance have included an in-depth analysis of the social and behavioural context in which hand hygiene is not undertaken. We used a mixed method approach to explore hand hygiene barriers in rural Indonesian healthcare facilities to develop a resource-appropriate adoption of international guidelines. Two hospitals and eight clinics (private and public) in a rural Indonesian district were studied for three months each. Hand hygiene compliance was covertly observed for two shifts each in three adult wards at two hospitals. Qualitative data were collected from direct observation, focus group discussions and semistructured in-depth and informal interviews within healthcare facilities and the community. Major barriers to compliance included longstanding water scarcity, tolerance of dirtiness by the community and the healthcare organisational culture. Hand hygiene compliance was poor (20%; 57/281; 95% CI: 16-25%) and was more likely to be undertaken after patient contact (34% after-patient contact vs 5% before-patient contact, Pperceived to be dirty (49% 'inherent' vs 11% 'elective' opportunities associated with clean contacts, Pcommitment to the provision of supportive working conditions.

Trichophyton tonsurans is an anthropophilic dermatophyte, frequent in the USA and in Asia where it is responsible for causing tinea capitis. At present, we attend an emergence of this species in certain regions where it was not or little met. Here, we report a case of onychomycosis of the hand due to T. tonsurans associated with non-albicans Candida species at an adult woman. The patient is a 62-year-old woman, with hypertension and diabetes. She reports the rather frequent use of chemical cleaners for the housework. She presented one year previously a distal onycholysis of the last four fingers of the left hand. The clinical examination objectified a presence of intertrigo in the second interdigital space. The mycological examination showed at the direct examination mycelial elements and the culture allowed the isolation of T. tonsurans associated with non-albicans Candida species. Our observation highlights especially the identification of a species, which has been described only once in Morocco about a case with onychomycosis of the feet. A possible emergence of this species in our country is not far from being possible. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

To improve hand hygiene in two outpatient health care clinics through the introduction of a gel sanitizer and an informational poster. In this interventional study, health care workers at two outpatient clinics were observed for frequency of hand hygiene (attempts versus opportunities). Gel sanitizer and informational posters were introduced together as an intervention. Direct observation of the frequency of hand hygiene was performed during baseline, intervention, and follow-up. A poststudy survey of health care workers was also distributed and collected. In both clinics, the frequency of hand hygiene was poor at baseline (11% and 21%) but improved significantly after intervention (36% and 54%) and was maintained through the follow-up period (32% and 51%). Throughout the study, postcontact hand hygiene was observed significantly more often than precontact hand hygiene. In both clinics, health care workers reported a preference for soap and water; yet observations showed that when the intervention made gel sanitizer available, sanitizer use predominated. Fifty percent of the surveyed health care workers considered the introduction of gel sanitizer to be an effective motivating tool for improving hand hygiene. Hand hygiene performance by health care workers in outpatient clinics may be improved through promoting the use of gel sanitizer and using informational posters. Compared with surveys, direct observation by trained observers may provide more accurate information about worker preferences for hand hygiene tools.

The attendance mandate for the medical course in Melaka Manipal Medical College, Manipal, India was increased from 75% to 90% based on the assumption that the mandatory increase will improve the students' performance. To find out whether there is any correlation between class attendance and academic performance. This was an institution based retrospective analytical study. Students who have completed Phase I (first two and a half years) of the MBBS course were included in the study. Student marks and attendance, from the database were obtained from three random batches, each, from two clusters A and B respectively. Those who had a mandatory attendance requirement of 75% belonged to A (n = 243), and those who had a mandatory attendance percentage of 90% belonged to B (n = 360). Statistical analyses performed included, Pearson 2 tailed correlation to correlate class attendance with student performance; Cluster analysis to classify group average in a similarity matrix; t-test to determine significance of difference in percentage of students who attained 100% when the college changed mandatory attendance from 75% to 90%; Mann-Whitney test to find out if there was a better performance in university exam when attendance policy changed. There was a significant correlation between attendance and the students who passed in the University exam. The number of students in the pass category was maximum (>90%) compared to students in distinction and failed categories. Percentage of students with 100% attendance rose from 4% (n = 10) to 11% (n = 40) when the mandatory attendance was increased from 75% to 90%. Attendance policy correlated with better academic performance. Reducing absenteeism, probably contributed to the improved academic performance of the students. But the link between attendance and best and worst performances could not be predicted because of small numbers in every batch.

The aim was to evaluate the usability of fidelity measures in compliance evaluation of hand hygiene. Adherence to hand hygiene guidelines is important in terms of patient safety. Compliance measures seldom describe how exactly the guidelines are followed. A cross-sectional observation study in a university hospital setting was conducted. Direct observation by trained staff was performed using a standardised observation form supplemented by fidelity criteria. A total of 830 occasions were observed in 13 units. Descriptive statistics (frequency, mean, percentages and range) were used as well as compliance rate by using a standard web-based tool. In addition, the binomial standard normal deviate test was conducted for comparing different methods used in evaluation of hand hygiene and in comparison between professional groups. Measuring fidelity to guidelines was revealed to be useful in uncovering gaps in hand hygiene practices. The main gap related to too short duration of hand rubbing. Thus, although compliance with hand hygiene guidelines measured using a standard web-based tool was satisfactory, the degree of how exactly the guidelines were followed seemed to be critical. Combining the measurement of fidelity to guidelines with the compliance rate is beneficial in revealing inconsistency between optimal and actual hand hygiene behaviour. Evaluating fidelity measures is useful in terms of revealing the gaps between optimal and actual performance in hand hygiene. Fidelity measures are suitable in different healthcare contexts and easy to measure according to the relevant indicators of fidelity, such as the length of hand rubbing. Knowing the gap facilitates improvements in clinical practice. © 2015 John Wiley & Sons Ltd.

An in situ hand calibration method using a pseudo-observation scheme for low-end inertial measurement units

2012-01-01

MEMS chips have become ideal candidates for various applications since they are small sized, light weight, have low power consumption and are extremely low cost and reliable. However, the performance of MEMS sensors, especially their biases and scale factors, is highly dependent on environmental conditions such as temperature. Thus a quick and convenient calibration is needed to be conducted by users in field without any external equipment or any expert knowledge of calibration. A novel and efficient in situ hand calibration method is presented to meet these demands in this paper. The algorithm of the proposed calibration method makes use of the navigation algorithm of the loosely-coupled GPS/INS integrated systems, but replaces the GPS observations with a kind of pseudo-observations, which can be stated as follows: if an inertial measurement unit (IMU) was rotating approximately around its measurement center, the range of its position and its linear velocity both would be within a limited scope. Using a Kalman filtering algorithm, the biases and scale factors of both accelerometer triad and gyroscope triad can be calibrated together within a short period (about 30 s), requiring only motions by hands. Real test results show that the proposed method is suitable for most consumer grade MEMS IMUs due to its zero cost, easy operation and sufficient accuracy. (paper)

Children enrolled in child care are 2.3-3.5 times more likely to experience acute gastrointestinal illness than children cared for in their own homes. The purpose of this study was to determine the frequency surfaces were touched by child care providers to identify surfaces that should be cleaned and sanitized. Observation data from a convenience sample of 37 child care facilities in North Carolina and South Carolina were analyzed. Trained data collectors used iPods (Apple, Cupertino, CA) to record hand touch events of 1 child care provider for 45 minutes in up to 2 classrooms in each facility. Across the 37 facilities, 10,134 hand contacts were observed in 51 classrooms. Most (4,536) were contacts with porous surfaces, with an average of 88.9 events per classroom observation. The most frequently touched porous surface was children's clothing. The most frequently touched nonporous surface was food contact surfaces (18.6 contacts/observation). Surfaces commonly identified as high-touch surfaces (ie, light switches, handrails, doorknobs) were touched the least. General cleaning and sanitizing guidelines should include detailed procedures for cleaning and sanitizing high-touch surfaces (ie, clothes, furniture, soft toys).

Epidemiology of Mental Health Attendances at Emergency Departments: Systematic Review and Meta-Analysis.

Directory of Open Access Journals (Sweden)

Helen Barratt

Full Text Available The characteristics of Emergency Department (ED attendances due to mental or behavioural health disorders need to be described to enable appropriate development of services. We aimed to describe the epidemiology of mental health-related ED attendances within health care systems free at the point of access, including clinical reason for presentation, previous service use, and patient sociodemographic characteristics.Systematic review and meta-analysis of observational studies describing ED attendances by patients with common mental health conditions.18 studies from seven countries met eligibility criteria. Patients attending due to mental or behavioural health disorders accounted for 4% of ED attendances; a third were due to self-harm or suicidal ideation. 58.1% of attendees had a history of psychiatric illness and up to 58% were admitted. The majority of studies were single site and of low quality so results must be interpreted cautiously.Prevalence studies of mental health-related ED attendances are required to enable the development of services to meet specific needs.

Over 5 million children attend the Emergency Department (ED) annually in England with an ever-increasing paediatric emergency caseload echoed globally. Approximately 60% of children present with illness and the majority have non-urgent illness creating burgeoning pressures on children's ED and this crisis resonates globally. To date no qualitative systematic review exists that focuses on the parental reasons for childhood attendance at the ED in this sub-group. To identify parental reasons for attending ED for their children presenting with minor illness. A qualitative systematic review was conducted against inclusion/exclusion criteria. Five electronic databases and key journals were searched in June 2015. 471 studies were identified and following study selection, 4 qualitative studies were included. Nine themes were identified e.g. dissatisfaction with family medical services, perceived advantages of ED and 'child suffering' with novel and insightful sub-themes of 'hereditary anxiety', 'taking it off our hands', ED as a 'magical place'. This novel qualitative systematic review examined parental attendance presenting with childhood minor illness of interest to emergency care reformers and clinicians. ED attendance is complex and multifactorial but parents provide vital insight to ED reformers on parental reasons for ED attendance in this sub-group. Copyright © 2017 Elsevier Ltd.

The use of health services has seen a steep rise. The frequent users are responsible for significant economic, human and social impact. The objective is to analyze the characteristics of frequent attenders in our Health Center, in order to evaluate the possibility of taking corrective measures to improve the quality of care and efficiency in the use of resources. Descriptive observational study of a sample of 379 patients over 18 years old. The dependent variables were attendance (number of visits to their family doctor during the previous year), frequent attendance (10 or more visits to the family doctor in the last year), and persistent frequent attenders (10 or more visits to the family doctor in each of the last two years). Data were collected from medical records and by telephone interview. The mean attendance was 6.83 (95%CI: 6.13-7.53), frequent attendance reached 25.4% (95%CI: 21.4-29.6), and persistent frequent attenders, 1.6% (95%CI: 0.5-2.9). Frequent attendance was associated with sex, age, marital status, educational level, family structure, existence of chronic disease, use of anxiolytic and antidepressants, request for additional tests, and referrals to other specialists, proximity to the health center, and level of satisfaction with their family doctor. The low persistent frequent attenders found suggests that frequent attendance could be largely due to factors related to professional and organization. Studies are required to address the high level of consumption of psychotropic drugs, and improving professional skills in dealing with mental problems.

Kuruno, Noriko; Kasahara, Kei; Mikasa, Keiichi

2017-08-01

The use of gloves for every patient contact (ie, universal gloving) has been suggested as an infection prevention adjunct and alternative to contact precautions. However, gloves may carry organisms unless they are changed properly. In addition, hand hygiene is required before donning and after removing gloves, and there are scarce data regarding glove changing and hand hygiene in a universal gloving setting. This nonrandomized observational before-after study evaluated the effect of education and feedback regarding hand hygiene. Compliance with hand hygiene and glove use was directly observed in a universal gloving setting at a 10-bed intensive care unit in a Japanese tertiary care university teaching hospital. A total of 6,050 hand hygiene opportunities were identified. Overall, hand hygiene compliance steadily increased from study period 1 (16.1%) to period 5 (56.8%), although there were indication-specific differences in the baseline compliance, the degree of improvement, and the reasons for noncompliance. There were decreases in the compliance with universal gloving and the incidence of methicillin-resistant Staphylococcus aureus. It is difficult to properly perform glove use and hand hygiene in a universal gloving setting, given its complexity. Direct observation with specific feedback and education may be effective in improving compliance. Copyright © 2017 Association for Professionals in Infection Control and Epidemiology, Inc.

The development of rhythmic attending in auditory sequences: attunement, referent period, focal attending.

Drake, C; Jones, M R; Baruch, C

2000-12-15

This paper is divided into three sections. The first section is theoretical; it extends Dynamic Attending Theory (Jones, M. R. Psychological Review 83 (1976) 323; Jones, M. R. Perception and Psychophysics 41(6) (1987) 631; Jones, M. R. Psychomusicology 9(2) (1990) 193; Jones, M. R., & Boltz, M. Psychological Review 96(3) (1989) 459) to developmental questions concerning tempo and time hierarchies. Generally Dynamic Attending Theory proposes that, when listening to a complex auditory sequence, listeners spontaneously focus on events occurring at an intermediate rate (the referent level), and they then may shift attention to events occurring over longer or shorter time spans, that is at lower (faster) or higher (slower) hierarchical levels (focal attending). The second section of the paper is experimental. It examines maturational changes of three dynamic attending activities involving referent period and level, attunement, and focal attending. Tasks involve both motor tapping (including spontaneous motor tempo and synchronization with simple sequences and music) and tempo discrimination. We compare performances by 4-, 6-, 8-, and 10-year-old children and adults, with or without musical training. Results indicate three changes with increased age and musical training: (1) a slowing of the mean spontaneous tapping rate (a reflection of the referent period) and mean synchronization rate (a reflection of the referent level), (2) enhanced ability to synchronize tapping and discriminate tempo (improved attunement), and (3) an enlarged range of tapping rates towards slower rates and higher hierarchical levels (improved focal attending). A final section considers results in light of the theory proposed here. It is suggested that growth trends can be expressed in terms of listeners' engagement of slower attending oscillators with age and experience, accompanied by the passage from the initial use of a single oscillator towards the coupling of multiple oscillators.

Palliative and Supportive Care in Acrometastasis to the Hand: Case Series

Directory of Open Access Journals (Sweden)

Narendra Kumar

2011-01-01

Full Text Available Acrometastasis to the hand is an unusual presentation which might mimic an infectious, inflammatory, or a metabolic pathology. We herein describe a case series of three patients of acrometastasis to the hand. We encountered three cases of acrometastasis to the hand attending the departmental clinics from 2007 to 2010. The median age at presentation was noted to be 55 years. All were males. The primaries included squamous cell carcinoma of the skin, larynx, and esophagus. In two patients, acrometastasis was detected at presentation and in one it was detected 2 years postcompletion of radical therapy. Two patients were offered palliative radiation to acrometastasis, and best supportive care was given to one. Palliation achieved after radiation was noted to be modest to good. The brief report highlights the importance of the clinical awareness of metastatic dissemination to unusual sites in the face of increasing cancer survivorship. Acrometastasis portends a poor prognosis with limited survival, and optimal integration of the best supportive care is mandatory. A short course of hypofractionated palliative radiation therapy results in modest to good palliation.

Factors associated with non-attendance, opportunistic attendance and reminded attendance to cervical screening in an organized screening program: a cross-sectional study of 12,058 Norwegian women

Full Text Available Abstract Background Cervical cancer incidence and mortality may be reduced by organized screening. Participant compliance with the attendance recommendations of the screening program is necessary to achieve this. Knowledge about the predictors of compliance is needed in order to enhance screening attendance. Methods The Norwegian Co-ordinated Cervical Cancer Screening Program (NCCSP registers all cervix cytology diagnoses in Norway and individually reminds women who have no registered smear for the past three years to make an appointment for screening. In the present study, a questionnaire on lifestyle and health was administered to a random sample of Norwegian women. The response rate was 68%. To address the predictors of screening attendance for the 12,058 women aged 25-45 who were eligible for this study, individual questionnaire data was linked to the cytology registry of the NCCSP. We distinguished between non-attendees, opportunistic attendees and reminded attendees to screening for a period of four years. Predictors of non-attendance versus attendance and reminded versus opportunistic attendance were established by multivariate logistic regression. Results Women who attended screening were more likely than non-attendees to report that they were aware of the recommended screening interval, a history of sexually transmitted infections and a history of hormonal contraceptive and condom use. Attendance was also positively associated with being married/cohabiting, being a non-smoker and giving birth. Women who attended after being reminded were more likely than opportunistic attendees to be aware of cervical cancer and the recommended screening interval, but less likely to report a history of sexually transmitted infections and hormonal contraceptive use. Moreover, the likelihood of reminded attendance increased with age. Educational level did not significantly affect the women's attendance status in the fully adjusted models. Conclusions The

Global facilitation of attended features is obligatory and restricts divided attention.

In many common situations such as driving an automobile it is advantageous to attend concurrently to events at different locations (e.g., the car in front, the pedestrian to the side). While spatial attention can be divided effectively between separate locations, studies investigating attention to nonspatial features have often reported a "global effect", whereby items having the attended feature may be preferentially processed throughout the entire visual field. These findings suggest that spatial and feature-based attention may at times act in direct opposition: spatially divided foci of attention cannot be truly independent if feature attention is spatially global and thereby affects all foci equally. In two experiments, human observers attended concurrently to one of two overlapping fields of dots of different colors presented in both the left and right visual fields. When the same color or two different colors were attended on the two sides, deviant targets were detected accurately, and visual-cortical potentials elicited by attended dots were enhanced. However, when the attended color on one side matched the ignored color on the opposite side, attentional modulation of cortical potentials was abolished. This loss of feature selectivity could be attributed to enhanced processing of unattended items that shared the color of the attended items in the opposite field. Thus, while it is possible to attend to two different colors at the same time, this ability is fundamentally constrained by spatially global feature enhancement in early visual-cortical areas, which is obligatory and persists even when it explicitly conflicts with task demands.

Background Hand hygiene compliance has improved significantly through hand hygiene promotion programs that have included poster campaign, monitoring and performance feedback, and education with special attentions to perceived subjective norms. We investigated factors associated with improved hand hygiene compliance, focusing on whether the improvement of hand hygiene compliance is associated with changed perception toward hand hygiene among medical personnel. Materials and Methods Hand hygiene compliance and perceptions toward hand hygiene among medical personnel were compared between the second quarter of 2009 (before the start of a hand hygiene promotion program) and the second quarter of 2012. We assessed adherence to hand hygiene among medical personnel quarterly according to the WHO recommended method for direct observation. Also, we used a modified self-report questionnaire to collect perception data. Results Hand hygiene compliance among physicians and nurses improved significantly from 19.0% in 2009 to 74.5% in 2012 (P Hand hygiene compliance among the medical personnel continued to improve, with a slight decline in 2013. Perceptions toward hand hygiene improved significantly between 2009 and 2012. Specifically, improvements were evident in intention to adhere to hand hygiene, knowledge about hand hygiene methods, knowledge about hand hygiene indications including care of a dirty and a clean body site on the same patient, perceived behavioral and subjective norms, positive attitude toward hand hygiene promotion campaign, perception of difficulty in adhering to hand hygiene, and motivation to improve adherence to hand hygiene. Conclusions The examined hand hygiene promotion program resulted in improved hand hygiene compliance and perception toward hand hygiene among medical personnel. The improved perception increased hand hygiene compliance. Especially, the perception of being a role model for other colleagues is very important to improve hand hygiene

Effect of weather on football attendances

Energy Technology Data Exchange (ETDEWEB)

Cairns, J A

1984-01-01

On the premise that weather should have an effect on spectator attendance at sports events in outdoor settings (a topic which has received surprisingly little formalized study), the author examined the record of home attendances for three football teams in Scotland. In general, it was found that the greater the rainfall on the day of the match the lower the attendance. Dividing spectators into different groups, it was further found that an additional hour of sunshine was associated 162 more adults attending Aberdeen matches, while high temperatures appeared to increase juvenile attendance (by 57 for ever 1 deg. C. rise in temperature). Weather disruption of football games is attended by a number of costs, both direct and indirect. Quantifying the impact of weather can shed substantial light on the problem of scheduling for the season. For example, since certain periods are, on average, wetter than others, rescheduling to drier periods might encourage greater attendance.

Hand Osteoblastoma

2006-06-01

Full Text Available Background and Aim: Osteoblastoma is one of the rarest primary bone tumors. Although, small bones of the hands and feet are the third most common location for this tumor, the hand involvement is very rare and few case observations were published in the English-language literature. Materials and Methods: In this study, we report five cases of benign osteoblastoma of the hand, 3 in metacarpals and two in phalanxes. The clinical feature is not specific. The severe nocturnal, salicylate-responsive pain is not present in patients with osteoblastoma. The pain is dull, persistent and less localized. The clinical course is usually long and there is often symptoms for months before medical attention are sought. Swelling is a more persistent finding in osteoblastoma of the hand that we found in all of our patients. The radiologic findings are indistinctive, so preoperative diagnosis based on X-ray appearance is difficult. In all of our 5 cases, we fail to consider osteoblastoma as primary diagnosis. Pathologically, osteoblastoma consisting of a well-vascularized connective tissue stroma in which there is active production of osteoid and primitive woven bone. Treatment depends on the stage and localization of the tumor. Curettage and bone grafting is sufficient in stage 1 or stage 2, but in stage 3 wide resection is necessary for prevention of recurrence. Osteosarcoma is the most important differential diagnosis that may lead to inappropriate operation.

Right-handed sneutrino as cold dark matter

Asaka, Takehiko; Ishiwata, Koji; Moroi, Takeo

2006-01-01

We consider supersymmetric models with right-handed neutrinos where neutrino masses are purely Dirac-type. In this model, right-handed sneutrino can be the lightest supersymmetric particle and can be a viable candidate of cold dark matter of the universe. Right-handed sneutrinos are never thermalized in the early universe because of weakness of Yukawa interaction, but are effectively produced by decays of various superparticles. We show that the present mass density of right-handed sneutrino can be consistent with the observed dark matter density

Use of a patient empowerment tool for hand hygiene.

Patient empowerment is recognized as an important component of a multimodal strategy to improve hand hygiene adherence. We examined the attitudes of adult patients and parents of pediatric patients toward a new patient empowerment tool (PET) at our hospital. We also surveyed physicians to determine their perceptions about the PET. A cross-sectional survey was performed of hospitalized children's parents and adult patients in a 531-bed tertiary care teaching hospital in West Virginia. Surveys were anonymous and self-administered. A separate survey was administered via e-mail to resident and attending physicians from the departments of internal medicine, pediatrics, and family medicine. Most parents and adult patients felt it was their role to speak up if a provider did not perform hand hygiene, but a smaller number actually felt comfortable using the PET. Only 54.9% of physicians felt that patients should be involved in reminding providers to perform hand hygiene. Overall, physicians indicated that they would prefer a patient to use words rather than the PET to remind them to perform hand hygiene. In our study, parents and adult patients supported use of the PET, but physicians were less supportive. As the patient empowerment movement grows, we should work to improve physician acceptance of patient involvement if it is to be successful.

Al-Arfaj, Abdurhman S.; Al-Boukai, Ahmad A.

2005-01-01

The aim of the study was to characterize the pattern of radiographic changes in the hands and feet of rheumatoid arthritis in Saudi patients. The radiographs of hands and feet of rheumatoid arthritis patients attending rheumatology outpatient clinics of King Khalid University Hospital in Riyadh, Kingdom of Saudi Arabia, over the period extending from March to June 2001, were examined and reported for the presence of osteopenia, joint space narrowing, and erosions. Fifty-six rheumatoid arthritis patients were studied. Their mean age was 50 + 1.9 years, and mean disease duration was 9.07 + 0.84 years. Generalized osteopenia was seen in 16/56 (29%) and periarticular osteopenia in 38/56 (68%). Joint space narrowing was present in 9/56 (16%) of feet and 35/56 (63%) of hand x-rays. Erosions were seen in 3/56 (6%) of feet and in 22/56 (39%) of hand x-rays. Significant correlation was seen between joints space narrowing, joint erosions, and disease duration. Radiographic changes in hands and feet of Saudi rheumatoid arthritis patients are less severe than those reported from the West, and the pattern is also different with less affection of the feet.

In clinical practice it is important to be able to assess the function of the upper limb of the patient who has suffered a stroke. There is currently no systemic review that could identify assessment tools for the 'fine use of the hand' and 'use of both hand and arm'. Primary, to identify observational tools which can assess the fine use of the hand and the use of both hand and arm in patients with stroke sequels. Secondary, to analyze the bias risk in the included articles, describing and categorizing the clinical utility, validity and reliability. A search was carried in Medline, LILACS, SciELO and Open Grey, which included articles published until October 2015. Studies that validate assessing tools of the upper limb in subjects with a stroke sequel which evaluate the fine use of the hand and the use of both hand and arm were included. Eleven tools in evaluate observational haven been selected, which assess the fine use of the hand and the use of hand and arm. In every case both validity and reliability have been reported, but clinical utility has been less considered for assessment. The studies that researched these tools showed a high risk of bias in their development. ARAT-19 showed a lower bias risk, but when it has to do with applicability and the reference trial is taken into account, the level of concern is high.

Hand hygiene is an important component of infection control, which is critical to ensuring patients' safety in hospitals. Nursing students are regarded as healthcare workers in training and can also be vehicles of cross-contamination within the hospital. Thus, this study aimed to identify the predictors of hand hygiene practice among Saudi nursing students. A descriptive, cross-sectional, self-reported study was conducted among 198 Saudi nursing students. Knowledge, attitude, and practice of hand hygiene were assessed using the WHO Hand Hygiene Knowledge Questionnaire for Health-Care Workers and its adopted scales. A regression analysis was performed to identify the predictors of hand hygiene practice. The respondents demonstrated moderate knowledge of hand hygiene (mean 13.20±2.80). The majority displayed a moderate attitude toward hand hygiene (52.1%), while only a few reported a poor attitude (13.1%). Approximately 68.7%, 29.8%, and 1.5% of the respondents reported moderate, good, and poor practice of hand hygiene, respectively. Having a good attitude toward hand hygiene, being male, being aware that hand hygiene is an effective intervention in preventing healthcare-associated infections (HAIs), attendance at hand hygiene trainings and seminars, and being in the lower academic level of nursing education were identified as predictors of better hand hygiene practice. The importance of ensuring a positive attitude toward hand hygiene and improving awareness of hand hygiene is emphasized, as are educational interventions. Educational interventions should be implemented to reinforce knowledge and instill a positive attitude toward hand hygiene. Copyright © 2015 King Saud Bin Abdulaziz University for Health Sciences.

To evaluate the incidence of apical crack initiation during canal preparation with stainless steel K-files and hand protaper files (in vitro study). Sixty extracted mandibular premo-lar teeth are randomly selected and embedded in an acrylic tube filled with autopolymerizing resin. A baseline image of the apical surface of each specimen was recorded under a digital microscope (80×). The cervical and middle thirds of all samples were flared with #2 and #1 Gates-Glidden (GG) drills, and a second image was recorded. The teeth were randomly divided into four groups of 15 teeth each according to the file type (hand K-file and hand-protaper) and working length (WL) (instrumented at WL and 1 mm less than WL). Final image after dye penetration and photomicrograph of the apical root surface were digitally recorded. Maximum numbers of cracks were observed with hand protaper files compared with hand K-file at the WL and 1 mm short of WL. Chi-square testing revealed a highly significant effect of WL on crack formation at WL and 1 mm short of WL (p = 0.000). Minimum numbers of cracks at WL and 1 mm short of WL were observed with hand K-file and maximum with hand protaper files. Soni D, Raisingani D, Mathur R, Madan N, Visnoi S.

Motor imagery (MI) refers to the process of imagining the execution of a specific motor action without actually producing an overt movement. Two forms of MI have been distinguished: visual MI and kinesthetic MI. To distinguish between these forms of MI we employed an event related potential (ERP) study to measure interference effects induced by hand orientation manipulations in a hand laterality judgement task. We hypothesized that this manipulation should only affect kinesthetic MI but not visual MI. The ERPs elicited by rotated hand stimuli contained the classic rotation related negativity (RRN) with respect to palm view stimuli. We observed that laterally rotated stimuli led to a more marked RRN than medially rotated stimuli. This RRN effect was observed when participants had their hands positioned in either a straight (control) or an inward rotated posture, but not when their hands were positioned in an outward rotated posture. Posture effects on the ERP-RRN have not previously been studied. Apparently, a congruent hand posture (hands positioned in an outward rotated fashion) facilitates the judgement of the otherwise more demanding laterally rotated hand stimuli. These ERP findings support a kinesthetic interpretation of MI involved in solving the hand laterality judgement task. The RRN may be used as a non-invasive marker for kinesthetic MI and seems useful in revealing the covert behavior of MI in e.g. rehabilitation programs.

Using a public health perspective, this study examined the characteristics of mothers and fathers who attended, compared to those who did not attend, a community-based practitioner-led universally offered parenting program. Mothers (141) and fathers (96) of 4- to 5-year-olds completed a set of questionnaires, including their demographic characteristics, their child's behavioral and emotional problems, and their own parenting behavior. They were all then given the opportunity to attend level 2 of the Triple P--Positive Parenting Program. During the first six months of the study, 33 mothers and 11 fathers opted to attend the program. The relation between program attendance and parental characteristics was similar for mothers and fathers. In general, fathers, non-native and lower educated parents were less likely to attend the program. Mothers, but not fathers, were more likely to attend if they reported more child behavior problems, while fathers, but not mothers, were observed at a trend level to attend if they perceived their child as having more emotional problems. In addition, parents in general were more likely to attend if they used more harsh parenting strategies. Although the universal offer did not reach parents universally, generally those parents who needed it were more likely to attend. Furthermore, this study shows that different factors may impact mothers' and fathers' attendance; therefore, parental data should be analyzed separately and different recruitment strategies should be used for mothers and fathers. © 2015 the Nordic Societies of Public Health.

Hand functioning in children with cerebral palsy

Full Text Available Brain lesions may disturb hand functioning in children with cerebral palsy (CP, making it difficult or even impossible for them to perform several manual activities. Most conventional treatments for hand dysfunction in CP assume that reducing the hand dysfunctions will improve the capacity to manage activities (i.e., manual ability, MA. The aim of this study was to investigate the directional relationships (direct and indirect pathways through which hand skills influence MA in children with CP. A total of 136 children with CP (mean age: 10 years; range: 6–16 years; 35 quadriplegics, 24 diplegics, 77 hemiplegics were assessed. Six hand skills were measured on both hands: touch-pressure detection (Semmes-Weinstein aesthesiometer, stereognosis (Manual Form Perception Test, proprioception (passive mobilization of the metacarpophalangeal joints, grip strength (Jamar dynamometer, gross manual dexterity (Box and Block Test, and fine finger dexterity (Purdue Pegboard Test. MA was measured with the ABILHAND-Kids questionnaire. Correlation coefficients were used to determine the linear associations between observed variables. A path analysis of structural equation modeling was applied to test different models of causal relationships among the observed variables. Purely sensory impairments did seem not to play a significant role in the capacity to perform manual activities. According to path analysis, gross manual dexterity in both hands and stereognosis in the dominant hand were directly related to MA, whereas grip strength was indirectly related to MA through its relationship with gross manual dexterity. However, one-third of the variance in MA measures could not be explained by hand skills. It can be concluded that MA is not simply the integration of hand skills in daily activities and should be treated per se, supporting activity-based interventions.

Complementary Hand Responses Occur in Both Peri- and Extrapersonal Space.

Directory of Open Access Journals (Sweden)

Full Text Available Human beings have a strong tendency to imitate. Evidence from motor priming paradigms suggests that people automatically tend to imitate observed actions such as hand gestures by performing mirror-congruent movements (e.g., lifting one's right finger upon observing a left finger movement; from a mirror perspective. Many observed actions however, do not require mirror-congruent responses but afford complementary (fitting responses instead (e.g., handing over a cup; shaking hands. Crucially, whereas mirror-congruent responses don't require physical interaction with another person, complementary actions often do. Given that most experiments studying motor priming have used stimuli devoid of contextual information, this space or interaction-dependency of complementary responses has not yet been assessed. To address this issue, we let participants perform a task in which they had to mirror or complement a hand gesture (fist or open hand performed by an actor depicted either within or outside of reach. In three studies, we observed faster reaction times and less response errors for complementary relative to mirrored hand movements in response to open hand gestures (i.e., 'hand-shaking' irrespective of the perceived interpersonal distance of the actor. This complementary effect could not be accounted for by a low-level spatial cueing effect. These results demonstrate that humans have a strong and automatic tendency to respond by performing complementary actions. In addition, our findings underline the limitations of manipulations of space in modulating effects of motor priming and the perception of affordances.

Crucially, whereas mirror-congruent responses don't require physical interaction with another person, complementary actions often do. Given that most experiments studying motor priming have used stimuli devoid of contextual information, this space or interaction-dependency of complementary responses has not yet been assessed. To address this issue, we let participants perform a task in which they had to mirror or complement a hand gesture (fist or open hand) performed by an actor depicted either within or outside of reach. In three studies, we observed faster reaction times and less response errors for complementary relative to mirrored hand movements in response to open hand gestures (i.e., 'hand-shaking') irrespective of the perceived interpersonal distance of the actor. This complementary effect could not be accounted for by a low-level spatial cueing effect. These results demonstrate that humans have a strong and automatic tendency to respond by performing complementary actions. In addition, our findings underline the limitations of manipulations of space in modulating effects of motor priming and the perception of affordances.

The amount of guidance provided by the attending surgeon in the operating room (OR) is a key element in developing residents' autonomy. The purpose of this study is to explore factors that affect attending surgeons' decision making regarding OR guidance provided to the resident. We used video-stimulated recall interviews (VSRI) throughout this 2-phase study. In Phase 1, 3 attending surgeons were invited to review separately 30 to 45 minute video segments of their prerecorded surgical operations to explore factors that influenced their OR guidance decision making. In Phase 2, 3 attending surgeons were observed and documented in the OR (4 operations, 341min). Each operating surgeon reviewed their videotaped surgical performance within 5 days of the operation to reflect on factors that affected their decision making during the targeted guidance events. All VSRI were recorded. Thematic analysis and manual coding were used to synthesize and analyze data from VSRI transcripts, OR observation documents, and field notes. A total of 255 minutes of VSRI involving 6 surgeons and 7 surgical operations from 5 different procedures were conducted. A total of 13 guidance decision-making influence factors from 4 categories were identified (Cohen's κ = 0.674): Setting (case schedule and patient morbidity), content (procedure attributes and case progress), resident (current competency level, trustworthiness, self-confidence, and personal traits), and attending surgeon (level of experience, level of comfort, preferred surgical technique, OR training philosophy, and responsibility as surgeon). A total of 5 factors (case schedule, patient morbidity, procedure attributes, resident current competency level, and trustworthiness) influenced attending surgeons' pre-OR guidance plans. "OR training philosophy" and "responsibility as surgeon" were anchor factors that affected attending surgeons' OR guidance decision-making patterns. Surgeons' OR guidance decision making is a dynamic process

To observe the formation of canal aberrations in S-shaped root canals prepared by every file of hand-used ProTaper. Fifteen S-shaped simulated resin root canals were selected. Each root canal was prepared by every file of hand-used ProTaper following the manufacturer instruction. The images of canals prepared by S1, S2, F1, F2 and F3 were taken and stored, which were divided into group S1, S2, F1, F2 and F3. One image of canal unprepared was superposed with the images of the same root canal in these five groups respectively to observe the types and number of canal aberrations, which included unprepared area, danger zone, ledge, elbow, zip and perforation. SPSS12.0 software pakage was used for Fisher's exact probabilities in 2x2 table. Unprepared area decreased following preparation by every file of ProTaper, but it still existed when the canal preparation was finished. The incidence of danger zone, elbow and zip in group F1 was 15/15, 11/15, 4/15, respectively, which was significantly higher than that in group S2(2/15,0,0) (PProTaper.The presence of unprepared area suggests that it is essential to rinse canal abundantly during complicated canal preparation and canal antisepsis after preparation.

The aim is to determine, from the patient's perspective, what constitutes a good hand-off procedure in the emergency department (ED). The secondary purpose is to evaluate what impact a formalized hand-off had on patient knowledge, throughput and customer service This study used a randomized controlled clinical trial involving two unique hand-off approaches and a convenience sample. The study alternated between the current hand-off process that documented the process but not specific elements (referred to as the informal process) to one using the IPASS the BATON process (considered the formal process). Consenting patients completed a 12-question validated questionnaire on how the process was perceived by patients and about their understanding why they waited in the ED. Statistical analysis using SPSS calculated descriptive frequencies and t-tests. In total 107 patients were enrolled: 50 in the informal and 57 in the formal group. Most patients had positive answers to the customer survey. There were significant differences between formal and informal groups: recalling the oncoming and outgoing physician coming to the patient's bed (p = 0.000), with more formal group recalling that than informal group patients; the oncoming physician introducing him/herself (p = 0.01), with more from the formal group answering yes and the physician discussing tests and implications with formal group patients (p = 0.02). This study was done at an urban inner city ED, a fact that may have skewed its results. A comparison of suburban and rural EDs would make the results stronger. It also reflected a very high level of customer satisfaction within the ED. This lack of variance may have meant that the correlation between customer service and handoffs was missed or underrepresented. There was no codified observation of either those using the IPASS the BATON script or those using informal procedures, so no comparison of level and types of information given between the two groups was done

Appropriate hand hygiene reduces hospital-acquired infections. Anesthesiologists work in environments with numerous hand hygiene opportunities (HHOs). In a prospective observational study, we investigated the potential for an anesthesiologist to return a positive alcohol breath test during routine practice when using alcohol hand gel. We observed ten volunteer anesthesiologists over four hours while they implemented the World Health Organization (WHO) "five moments for hand hygiene" using our hospital's adopted standard 70% ethanol hand gel. We measured the expired alcohol concentration at shift start and every fifteen minutes thereafter with a fuel cell breathalyzer calibrated to measure the percentage of blood alcohol concentration (BAC). Blood alcohol specimens (analyzed with gas chromatography) were collected at shift start and, when possible, immediately after a participant's first positive breathalyzer test. Of the 130 breathalyzer tests obtained, there were eight (6.2%) positive breath alcohol results from six of the ten participants, all within two minutes of a HHO. The highest value breathalyzer BAC recorded was 0.064%, with an overall mean (SD) of 0.023 (0.017)%. Five (62.5%) of the positive breathalyzer tests returned to zero in less than seven minutes. All of three blood specimens obtained immediately after a positive breathalyzer reading tested negative for alcohol. Anesthesia practitioners using alcohol hand gel in a manner that conforms with recommended hand hygiene can test positive for alcohol on a breathalyzer assay. Positive tests probably arose from inhalation of alcohol vapour into the respiratory dead space following gel application. If workplace breath testing for alcohol is implemented, it should be completed more than 15 min after applying alcohol hand gel. Positive results should be verified with a BAC test.

Frequent attendance to the emergency department (ED) is a growing public health concern. Designing services for frequent attenders poses challenges, given the heterogeneous nature of this group. This was a two-part observational study identifying frequent attenders from ED records. The first stage studied trends and developed personas with emphasis on differentiating moderate frequent attenders (attending between 5 and 20 times per year) and extreme frequent attenders (attending more than 20 times). Stage 2 included a case note review of 100 consecutive frequent attenders. Results showed an increase in frequent attendance from 2.59% to 4.12% over 8 years. Moderate frequent attenders accounted for 97%. Of the 100 frequent attenders studied, 45% had medically unexplained symptoms (MUS), associated with younger age (p0.05). In conclusion, the ED is a useful hub for identifying frequent attenders with MUS, particularly among moderate frequent attenders; service design for this group should consider a 'whole-systems approach' with integration between primary and secondary care, including specialist liaison psychiatry services where appropriate. © 2016 Royal College of Physicians.

Self-Sampling for Human Papillomavirus Testing among Non-Attenders Increases Attendance to the Norwegian Cervical Cancer Screening Programme.

Transmission of viruses, bacteria, and parasites to food by way of improperly washed hands is a major contributing factor in the spread of foodborne illnesses. Field observers have assessed compliance with hand washing regulations, yet few studies have included consideration of frequency and methods used by sectors of the food service industry or have included benchmarks for hand washing. Five 3-h observation periods of employee (n = 80) hand washing behaviors during menu production, service, and cleaning were conducted in 16 food service operations for a total of 240 h of direct observation. Four operations from each of four sectors of the retail food service industry participated in the study: assisted living for the elderly, childcare, restaurants, and schools. A validated observation form, based on 2005 Food Code guidelines, was used by two trained researchers. Researchers noted when hands should have been washed, when hands were washed, and how hands were washed. Overall compliance with Food Code recommendations for frequency during production, service, and cleaning phases ranged from 5% in restaurants to 33% in assisted living facilities. Procedural compliance rates also were low. Proposed benchmarks for the number of times hand washing should occur by each employee for each sector of food service during each phase of operation are seven times per hour for assisted living, nine times per hour for childcare, 29 times per hour for restaurants, and 11 times per hour for schools. These benchmarks are high, especially for restaurant employees. Implementation would mean lost productivity and potential for dermatitis; thus, active managerial control over work assignments is needed. These benchmarks can be used for training and to guide employee hand washing behaviors.

Predicting intention to attend and actual attendance at a universal parent-training programme: a comparison of social cognition models.

Thornton, Sarah; Calam, Rachel

2011-07-01

The predictive validity of the Health Belief Model (HBM) and the Theory of Planned Behaviour (TPB) were examined in relation to 'intention to attend' and 'actual attendance' at a universal parent-training intervention for parents of children with behavioural difficulties. A validation and reliability study was conducted to develop two questionnaires (N = 108 parents of children aged 4-7).These questionnaires were then used to investigate the predictive validity of the two models in relation to 'intention to attend' and 'actual attendance' at a parent-training intervention ( N = 53 parents of children aged 4-7). Both models significantly predicted 'intention to attend a parent-training group'; however, the TPB accounted for more variance in the outcome variable compared to the HBM. Preliminary investigations highlighted that attendees were more likely to intend to attend the groups, have positive attitudes towards the groups, perceive important others as having positive attitudes towards the groups, and report elevated child problem behaviour scores. These findings provide useful information regarding the belief-based factors that affect attendance at universal parent-training groups. Possible interventions aimed at increasing 'intention to attend' and 'actual attendance' at parent-training groups are discussed.

Hands of early primates.

Questions surrounding the origin and early evolution of primates continue to be the subject of debate. Though anatomy of the skull and inferred dietary shifts are often the focus, detailed studies of postcrania and inferred locomotor capabilities can also provide crucial data that advance understanding of transitions in early primate evolution. In particular, the hand skeleton includes characteristics thought to reflect foraging, locomotion, and posture. Here we review what is known about the early evolution of primate hands from a comparative perspective that incorporates data from the fossil record. Additionally, we provide new comparative data and documentation of skeletal morphology for Paleogene plesiadapiforms, notharctines, cercamoniines, adapines, and omomyiforms. Finally, we discuss implications of these data for understanding locomotor transitions during the origin and early evolutionary history of primates. Known plesiadapiform species cannot be differentiated from extant primates based on either intrinsic hand proportions or hand-to-body size proportions. Nonetheless, the presence of claws and a different metacarpophalangeal [corrected] joint form in plesiadapiforms indicate different grasping mechanics. Notharctines and cercamoniines have intrinsic hand proportions with extremely elongated proximal phalanges and digit rays relative to metacarpals, resembling tarsiers and galagos. But their hand-to-body size proportions are typical of many extant primates (unlike those of tarsiers, and possibly Teilhardina, which have extremely large hands). Non-adapine adapiforms and omomyids exhibit additional carpal features suggesting more limited dorsiflexion, greater ulnar deviation, and a more habitually divergent pollex than observed plesiadapiforms. Together, features differentiating adapiforms and omomyiforms from plesiadapiforms indicate increased reliance on vertical prehensile-clinging and grasp-leaping, possibly in combination with predatory behaviors in

Nosocomial infections are the main problems rising morbidity and mortality in health care settings. Hand hygiene is the most effective method for preventing these infections. In this study, we aimed to investigate the factors related with hand hygiene adherence at a private hospital in Turkey. This study was conducted between March and June 2010 at a private hospital in Turkey. During the observation period, employees were informed about training, then posters and images were hanged in specific places of the hospital. After the initial observation, training on nosocomial infections and hand hygiene was provided to the hospital staff in March 2010. Contacts were classified according to occupational groups and whether invasive or not. These observations were evaluated in terms of compatibility with hand hygiene guidelines. Hand hygiene adherence rate of trained doctors was higher than untrained ones before patient contact and after environment contact [48% (35/73) versus 82% (92/113) pHand hygiene adherence rate of trained nurses was higher than untrained ones before patient contact [63% (50/79) versus 76% (37/49) pHand hygiene adherence rate of trained assistant health personnel was higher than untrained ones before asepsis [20% (2/10) versus 73% (16/22) phand antiseptics were used when hand washing was not possible. The increase at the rate of hand washing after training reveals the importance of feedback of the observations, as well as the training. One of the most important ways of preventing nosocomial infections is hand hygiene training that should be continued with feedbacks.

Back to basics: hand hygiene and surgical hand antisepsis.

Spruce, Lisa

2013-11-01

Health care-associated infections (HAIs) are a significant issue in the United States and throughout the world, but following proper hand hygiene practices is the most effective and least expensive way to prevent HAIs. Hand hygiene is inexpensive and protects patients and health care personnel alike. The four general types of hand hygiene that should be performed in the perioperative environment are washing hands that are visibly soiled, hand hygiene using alcohol-based products, surgical hand scrubs, and surgical hand scrubs using an alcohol-based surgical hand rub product. Barriers to proper hand hygiene may include not thinking about it, forgetting, skin irritation, a lack of role models, or a lack of a safety culture. One strategy for improving hand hygiene practices is monitoring hand hygiene as part of a quality improvement project, but the most important aspect for perioperative team members is to set an example for other team members by following proper hand hygiene practices and reminding each other to perform hand hygiene.

2010-03-25

Breast screening uptake in London is below the Government's target of 70% and we investigate whether ethnicity affects this. Information on the ethnicity for the individual women invited is unavailable, so we use an area-based method similar to that routinely used to derive a geographical measure for socioeconomic deprivation. We extracted 742,786 observations on attendance for routine appointments between 2004 and 2007 collected by the London Quality Assurance Reference Centre. Each woman was assigned to a lower super output (LSOA) based on her postcode of residence. The proportions of the ethnic groups within each LSOA are known, so that the likelihood of a woman belonging to White, Black and Asian groups can be assigned. We investigated screening attendance by age group, socioeconomic deprivation using the Index of Deprivation 2004 income quintile, invitation type and breast screening service. Using logistic regression analysis we calculated odds ratios for attendance based on ethnic composition of the population, adjusting for age, socioeconomic status, the invitation type and screening service. The unadjusted attendance odds ratios were high for the White population (OR: 3.34 95% CI [3.26-3.42]) and low for the Black population (0.13 [0.12-0.13]) and the Asian population (0.55 [0.53-0.56]). Multivariate adjustment reduced the differences, but the Black population remained below unity (0.47 [0.44-0.50]); while the White (1.30 [1.26-1.35]) and Asian populations (1.10 [1.05-1.15]) were higher. There was little difference in the attendance between age groups. Attendance was highest for the most affluent group and fell sharply with increasing deprivation. For invitation type, the routine recall was higher than the first call. There were wide variations in the attendance for different ethnic groups between the individual screening services. Overall breast screening attendance is low in communities with large Black populations, suggesting the need to improve

Left Superior Temporal Gyrus Is Coupled to Attended Speech in a Cocktail-Party Auditory Scene.

Using a continuous listening task, we evaluated the coupling between the listener's cortical activity and the temporal envelopes of different sounds in a multitalker auditory scene using magnetoencephalography and corticovocal coherence analysis. Neuromagnetic signals were recorded from 20 right-handed healthy adult humans who listened to five different recorded stories (attended speech streams), one without any multitalker background (No noise) and four mixed with a "cocktail party" multitalker background noise at four signal-to-noise ratios (5, 0, -5, and -10 dB) to produce speech-in-noise mixtures, here referred to as Global scene. Coherence analysis revealed that the modulations of the attended speech stream, presented without multitalker background, were coupled at ∼0.5 Hz to the activity of both superior temporal gyri, whereas the modulations at 4-8 Hz were coupled to the activity of the right supratemporal auditory cortex. In cocktail party conditions, with the multitalker background noise, the coupling was at both frequencies stronger for the attended speech stream than for the unattended Multitalker background. The coupling strengths decreased as the Multitalker background increased. During the cocktail party conditions, the ∼0.5 Hz coupling became left-hemisphere dominant, compared with bilateral coupling without the multitalker background, whereas the 4-8 Hz coupling remained right-hemisphere lateralized in both conditions. The brain activity was not coupled to the multitalker background or to its individual talkers. The results highlight the key role of listener's left superior temporal gyri in extracting the slow ∼0.5 Hz modulations, likely reflecting the attended speech stream within a multitalker auditory scene. When people listen to one person in a "cocktail party," their auditory cortex mainly follows the attended speech stream rather than the entire auditory scene. However, how the brain extracts the attended speech stream from the whole

Overall, 41% of all work-related accidents lead to a hand injury. In the younger generation, the incidence rate even rises to 50%. In Austria, these accidents result in approximately half a million sick leave days per annum, an average of 12.5 days per accident. In comparison, leisure-time hand injuries show a significantly higher accident rate: 60% of hand injuries occur during leisure time. Far fewer safety measures are taken and a lack of adequate training and a disregard for safety recommendations are observed.This large number of hand injuries led to the launch of a campaign in Austria in 2014-2015 called "Hände gut - Alles Gut", (Hands well - all's well). This campaign was aimed at reducing the costs, a sum of 309 million Euros, incurred solely from work-related hand accidents, by at least 5-10%.These exorbitantly high costs are not only due to severe hand trauma, most result from a multitude of slight and superficial wounds.

To observe student nurses' overall and moment-specific hand hygiene compliance during clinical placement. Hand hygiene is the single most important measure to prevent healthcare-associated infections. However, research has shown low compliance among healthcare workers. During clinical placements, student nurses perform various nursing tasks and procedures to a large number of patients, requiring extensive patient contact. It is crucial that they practice correct hand hygiene to prevent healthcare-associated infections. Open, standardised and nonparticipating observations. Twenty-nine student nurses were observed three times for 20 ± 10 min during clinical placement in a Norwegian university hospital. To measure compliance, we used WHO's Hand Hygiene Observation tool, based on the model "My five moments for hand hygiene". Overall hand hygiene compliance in the student group was 83.5%. Highest moment-specific compliance was after touching patient surroundings, after touching patients and after body fluid exposure risk. Lowest moment-specific compliance was recorded before touching patients or patient surroundings, and before clean/aseptic procedures. Nurse education needs to be improved both theoretically and during clinical placements in order to advance and sustain compliance among student nurses. Increasing healthcare workers' compliance with hand hygiene guidelines remains a challenge to the clinical community. In order to reduce healthcare-associated infections, it is important to educate student nurses to comply with the guidelines during clinical placements. Identifying student nurses' hand hygiene performance is the first step towards developing teaching methods to improve and sustain their overall and moment-specific compliance. As a measure to ensure student compliance during clinical placements, mentors should be aware of their influence on students' performance, act as hand hygiene ambassadors, encourage students to comply with established guidelines

Human-inspired feedback synergies for environmental interaction with a dexterous robotic hand.

Kent, Benjamin A; Engeberg, Erik D

2014-11-07

Effortless control of the human hand is mediated by the physical and neural couplings inherent in the structure of the hand. This concept was explored for environmental interaction tasks with the human hand, and a novel human-inspired feedback synergy (HFS) controller was developed for a robotic hand which synchronized position and force feedback signals to mimic observed human hand motions. This was achieved by first recording the finger joint motion profiles of human test subjects, where it was observed that the subjects would extend their fingers to maintain a natural hand posture when interacting with different surfaces. The resulting human joint angle data were used as inspiration to develop the HFS controller for the anthropomorphic robotic hand, which incorporated finger abduction and force feedback in the control laws for finger extension. Experimental results showed that by projecting a broader view of the tasks at hand to each specific joint, the HFS controller produced hand motion profiles that closely mimic the observed human responses and allowed the robotic manipulator to interact with the surfaces while maintaining a natural hand posture. Additionally, the HFS controller enabled the robotic hand to autonomously traverse vertical step discontinuities without prior knowledge of the environment, visual feedback, or traditional trajectory planning techniques.

Effortless control of the human hand is mediated by the physical and neural couplings inherent in the structure of the hand. This concept was explored for environmental interaction tasks with the human hand, and a novel human-inspired feedback synergy (HFS) controller was developed for a robotic hand which synchronized position and force feedback signals to mimic observed human hand motions. This was achieved by first recording the finger joint motion profiles of human test subjects, where it was observed that the subjects would extend their fingers to maintain a natural hand posture when interacting with different surfaces. The resulting human joint angle data were used as inspiration to develop the HFS controller for the anthropomorphic robotic hand, which incorporated finger abduction and force feedback in the control laws for finger extension. Experimental results showed that by projecting a broader view of the tasks at hand to each specific joint, the HFS controller produced hand motion profiles that closely mimic the observed human responses and allowed the robotic manipulator to interact with the surfaces while maintaining a natural hand posture. Additionally, the HFS controller enabled the robotic hand to autonomously traverse vertical step discontinuities without prior knowledge of the environment, visual feedback, or traditional trajectory planning techniques.

Byrne, Abbey; Morgan, Alison

2011-11-01

Forty years of safe motherhood programming has demonstrated that isolated interventions will not reduce maternal mortality sufficiently to achieve MDG 5. Although skilled birth attendants (SBAs) can intervene to save lives, traditional birth attendants (TBAs) are often preferred by communities. Considering the value of both TBAs and SBAs, it is important to review strategies for maximizing their respective strengths. To describe mechanisms to integrate TBAs with the health system to increase skilled birth attendance and examine the components of successful integration. A systematic review of interventions linking TBAs and formal health workers, measuring outcomes of skilled birth attendance, referrals, and facility deliveries. Thirty-three articles met the selection criteria. Mechanisms used for integration included training and supervision of TBAs, collaboration skills for health workers, inclusion of TBAs at health facilities, communication systems, and clear definition of roles. Impact on skilled birth attendance depended on selection of TBAs, community participation, and addressing barriers to access. Successful approaches were context-specific. The integration of TBAs with formal health systems increases skilled birth attendance. The greatest impact is seen when TBA integration is combined with complementary actions to overcome context-specific barriers to contact among SBAs, TBAs, and women.

Previous reports have suggested that action observation training (AOT) is beneficial in enhancing the early learning of new motor tasks; however, EEG-based investigation has received little attention for AOT. The purpose of this study was to illustrate the effects of AOT on hand dexterity and cortical activation in patients with post-stroke hemiparesis. Twenty patients with post-stroke hemiparesis were randomly divided into either the experimental group (EG) or control group (CG), with 10 patients in each group. Prior to the execution of motor tasks (carrying wooden blocks from one box to another), subjects in the EG and CG observed a video clip displaying the execution of the same motor task and pictures showing landscapes, respectively. Outcome measures included the box and block test (BBT) to evaluate hand dexterity and EEG-based brain mapping to detect changes in cortical activation. The BBT scores (EG: 20.50 ± 6.62 at pre-test and 24.40 ± 5.42 at post-test; CG: 20.20 ± 6.12 at pre-test and 20.60 ± 7.17 at post-test) revealed significant main effects for the time and group and significant time-by-group interactions (p < 0.05). For the subjects in the EG, topographical representations obtained with the EEG-based brain mapping system were different in each session of the AOT and remarkable changes occurred from the 2nd session of AOT. Furthermore, the middle frontal gyrus was less active at post-test than at pre-test. These findings support that AOT may be beneficial in altering cortical activation patterns and hand dexterity.

The so-called 'myelopathy hand', or characteristic finger paralysis, often recognized in cervical compression myelopathy, has been considered a unique manifestation of cervical myelopathy. We used our original grip and release test, a 15-second test in which finger motion is captured with a digital camera, to investigate whether cervical radiculopathy has the same characteristics as myelopathy hand. Thirty patients with pure radiculopathy, id est (i.e.), who had radiating arm pain and evidence of corresponding nerve root impingement on X-ray images or MRI scans, but did not have spinal cord compression, served as the subjects. In contrast to other radiculopathies, C7 radiculopathy was manifested by a significant reduction in the number of finger motion cycles on the affected side in comparison with the unaffected side, the same as in myelopathy hand. Uncoordinated finger motion was significantly more frequent on the affected side in C6 radiculopathy than on the unaffected side. These findings contradict the conventional notion that myelopathy hand is a unique manifestation of cervical myelopathy, but some radiculopathies manifested the same kinds of finger paralysis observed in myelopathy hand.

The alien hand sign. Localization, lateralization and recovery.

Science.gov (United States)

Goldberg, G; Bloom, K K

1990-10-01

The alien hand sign was first described by Brion and Jedynak as a "feeling of estrangement between the patient and one of his hands." The affected hand frequently shows a grasp reflex and an instinctive grasp reaction as well as elements of what Denny-Brown referred to as a "magnetic apraxia" associated with frontal lobe damage. Most notably, however, the affected hand is observed to perform apparently purposive behaviors that are perceived as being outside the volitional control of the patient. The patients interpret the behavior of their own affected limb as being controlled by an external agent. They do not feel that they are initiating or controlling the behavior of the hand and often express dismay at the hand's "extravolitional" activity. The patients attempt to control behavior of the alien hand with the unimpaired hand by forcibly restraining the affected limb, an act that may be termed "self-restriction." In this paper, we report an additional four cases of alien hand sign in right-handed subjects: two involving the right hand and two involving the left hand. In each case, the clinical findings were associated with extensive unilateral damage of the medial frontal cortex of the hemisphere contralateral to the affected hand. Furthermore, the alien movement gradually disappears over the course of 6-12 months after the stroke. These clinical case studies are presented and discussed in the context of the "dual premotoer systems hypothesis," an anatomicophysiological model that proposes that action is organized by two separate but interactive premotor brain systems corresponding to evolutionarily defined medial and lateral cortical moieties. It is hypothesized that the alien mode behavior results from unconstrained activity of the lateral premotor system in the damaged hemisphere. The residual volitional control in the limb occurs through the activity of the intact medial premotor system of the ipsilateral hemisphere. Recovery may occur through extension of

Seventy-seven frequent attenders at an emergency department (ED) in an inner-city hospital in the UK (defined as seven or more visits in the previous 12 months) were compared with 182 patients who were attending the same department on a routine basis. Patients completed the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) and the Short Form (SF)-36. Information was obtained on 64% of the frequent attenders and 45% underwent a detailed psychiatric assessment. Of the frequent attenders, 45% had psychiatric disorder and 49% had some form of an alcohol-related disorder. Compared with routine attenders, frequent attenders reported lower health status, had more psychiatric disorder (odds ratio: OR=8.2, 95% confidence interval: CI=3.8--18.1), had more general hospital admissions (OR=19.9, 95% CI=8.3--47.8), more psychiatric admissions (OR=167.5, 95% CI=9.5--2959.0), and more GP visits (95% CI for difference=-10.2 to -5.7). There was no evidence that frequent attenders had more somatisation than routine attenders. Specific treatment and management strategies need to be developed for this group of patients, although a substantial proportion may be difficult to engage in the treatment process.

Hand hygiene is a key measure to prevent healthcare-associated infection. To promote hand hygiene nationally the German campaign 'Aktion Saubere Hände' was launched in January 2008, based on the World Health Organization's 'Clean Care is Safer Care' initiative. We report the first results from a full year of data collection on hand hygiene compliance recorded with the help of a renewed observation tool. Data were based on submissions from 109 participating hospitals collected from 576 wards between January 1st and December 31st, 2014. The overall median compliance was 73%, ranging from 55% (10th percentile) to 89% (90th percentile). The results demonstrated only small differences between adult and non-adult intensive care units (ICUs) with neonatal ICUs and paediatric non-ICUs maintaining higher compliance than adult care units. Performance among nurses was better than physicians, and overall rates of hand hygiene performance were significantly higher after patient contact than before.

Abstract Background: As reflected in the United Nations Millennium Development Goals (UN MDG 5), reducing maternal mortality represents an important area of concern. The common causes of maternal deaths may be preventable and treatable by having access to emergency obstetric care (EmOC), including skilled birth attendance (SBA), when needed. Measuring the presence of a birth attendant has been the main focus until now, not their skills and qualifications, and by this we cannot presuppose ...

Hands of beauty, hands of horror: fear and Egyptian art at the Fin de Siècle.

Science.gov (United States)

Briefel, Aviva

2008-01-01

This essay examines the gothicization of Egyptian manual productions in late-Victorian mummy narratives. These narratives often isolate the mummy's hand as a signifier of craftsmanship, a troubling object for a culture that was mourning the figurative loss of its artisans' hands to mechanized production. Focusing on Bram Stoker's 1903 novel, The Jewel of Seven Stars, I contend that the horror of the mummy's hand emanates from its ambiguous position as an artifact that is itself a means of production. It displaces Friedrich Engels's conception of the Western hand as a self-creating appendage into the atavistic domain of a long-lost Egyptian tradition, and in doing so, it forces the English observer to recognize the irrecoverable nature of aesthetic craftsmanship. Brought into violent contact with the creative potential of the mummy's hand, the characters in Stoker's novel try to disassociate the mummy from manual production but only succeed in confirming their own status as products of a mechanized age.

Neural responses to complex auditory rhythms: the role of attending

Directory of Open Access Journals (Sweden)

Heather L Chapin

2010-12-01

Full Text Available The aim of this study was to explore the role of attention in pulse and meter perception using complex rhythms. We used a selective attention paradigm in which participants attended to either a complex auditory rhythm or a visually presented word list. Performance on a reproduction task was used to gauge whether participants were attending to the appropriate stimulus. We hypothesized that attention to complex rhythms – which contain no energy at the pulse frequency – would lead to activations in motor areas involved in pulse perception. Moreover, because multiple repetitions of a complex rhythm are needed to perceive a pulse, activations in pulse related areas would be seen only after sufficient time had elapsed for pulse perception to develop. Selective attention was also expected to modulate activity in sensory areas specific to the modality. We found that selective attention to rhythms led to increased BOLD responses in basal ganglia, and basal ganglia activity was observed only after the rhythms had cycled enough times for a stable pulse percept to develop. These observations suggest that attention is needed to recruit motor activations associated with the perception of pulse in complex rhythms. Moreover, attention to the auditory stimulus enhanced activity in an attentional sensory network including primary auditory, insula, anterior cingulate, and prefrontal cortex, and suppressed activity in sensory areas associated with attending to the visual stimulus.

We report an experiment where participants observed an attack on their virtual body as experienced in an immersive virtual reality (IVR) system. Participants sat by a table with their right hand resting upon it. In IVR, they saw a virtual table that was registered with the real one, and they had a virtual body that substituted their real body seen from a first person perspective. The virtual right hand was collocated with their real right hand. Event-related brain potentials were recorded in two conditions, one where the participant's virtual hand was attacked with a knife and a control condition where the knife only struck the virtual table. Significantly greater P450 potentials were obtained in the attack condition confirming our expectations that participants had a strong illusion of the virtual hand being their own, which was also strongly supported by questionnaire responses. Higher levels of subjective virtual hand ownership correlated with larger P450 amplitudes. Mu-rhythm event-related desynchronization in the motor cortex and readiness potential (C3-C4) negativity were clearly observed when the virtual hand was threatened-as would be expected, if the real hand was threatened and the participant tried to avoid harm. Our results support the idea that event-related potentials may provide a promising non-subjective measure of virtual embodiment. They also support previous experiments on pain observation and are placed into context of similar experiments and studies of body perception and body ownership within cognitive neuroscience.

Two Polarities of Attention in Social Contexts: From Attending-to-Others to Attending-to-Self.

Science.gov (United States)

Kuang, Shenbing

2016-01-01

Social attention is one special form of attention that involves the allocation of limited processing resources in a social context. Previous studies on social attention often regard how attention is directed toward socially relevant stimuli such as faces and gaze directions of other individuals. In contrast to attending-to-others, a different line of researches has shown that self-related information such as own face and name automatically captures attention and is preferentially processed comparing to other-related information. These contrasting behavioral effects between attending-to-others and attending-to-self prompt me to consider a synthetic viewpoint for understanding social attention. I propose that social attention operates at two polarizing states: In one extreme, individual tends to attend to the self and prioritize self-related information over others', and, in the other extreme, attention is allocated to other individuals to infer their intentions and desires. Attending-to-self and attending-to-others mark the two ends of an otherwise continuum spectrum of social attention. For a given behavioral context, the mechanisms underlying these two polarities will interact and compete with each other in order to determine a saliency map of social attention that guides our behaviors. An imbalanced competition between these two behavioral and cognitive processes will cause cognitive disorders and neurological symptoms such as autism spectrum disorders and Williams syndrome. I have reviewed both behavioral and neural evidence that support the notion of polarized social attention, and have suggested several testable predictions to corroborate this integrative theory for understanding social attention.

Hand hygiene in hospital environments: use of conformity indicators

Directory of Open Access Journals (Sweden)

Thaíne Cristina Romualdo dos SANTOS

Full Text Available An exploratory descriptive study with a quantitative approach whose objective was to use indicators to evaluate the frequency and infrastructure for hand hygiene, as well as the nursing team's knowledge about the subject. Systematized observation was carried out at hospital in the state of São Paulo, Brazil of the routine activities of 33 participating professionals (nurses and technicians as well as the application of an individual questionnaire about the subject.1206 opportunities for hand hygiene were identified, though it was effected in only 481 (39.9% of them. Alcohol solution was not used at any opportunity. The infrastructure indicator for hand hygiene was close to the ideal value (83.3%. The professionals reported a high frequency of hand hygiene, demonstrating knowledge in relation to its importance, yet contradicting the findings of the observation. It was concluded that, despite the adequate infrastructure, hand hygiene was below that expected, requiring actions and strategies to overcomes these barrier and increase the use of alcohol solution.

Impact of regular soap provision to primary schools on hand washing and E. coli hand contamination among pupils in Nyanza Province, Kenya: a cluster-randomized trial.

2013-10-01

We assessed whether supplying soap to primary schools on a regular basis increased pupil hand washing and decreased Escherichia coli hand contamination. Multiple rounds of structured observations of hand washing events after latrine use were conducted in 60 Kenyan schools, and hand rinse samples were collected one time in a subset of schools. The proportion of pupils observed practicing hand washing with soap (HWWS) events was significantly higher in schools that received a soap provision intervention (32%) and schools that received soap and latrine cleaning materials (38%) compared with controls (3%). Girls and boys had similar hand washing rates. There were non-significant reductions in E. coli contamination among intervention school pupils compared with controls. Removing the barrier of soap procurement can significantly increase availability of soap and hand washing among pupils; however, we discuss limitations in the enabling policy and institutional environment that may have prevented reaching desired levels of HWWS.

Diarrhoea incidence has been increasing progressively over the past years in developed countries, including Singapore, despite the accessibility and availability to clean water, well-established sanitation infrastructures and regular hygiene promotion. The aim of this study is to determine the current knowledge, attitude and behaviour of hand and food hygiene, and the potential risk factors of diarrhoea in a residential community of Singapore. A cross-sectional study was conducted within a residential area in the west of Singapore from June to August 2013. A total of 1,156 household units were randomly sampled and invited to participate in an interviewer-assisted survey using standardised questionnaires. Descriptive, univariate and multivariate analyses were performed using descriptive statistics, Fisher's Exact test and multivariate logistic regression modelling, respectively. R program was used for all statistical analysis. All tests were conducted at 5% level of significance with 95% confidence intervals (CI) reported where applicable. A total of 240 units (20.8%) consented and responded to the survey invitation. About 77% of the expected knowledge and attitude were observed in at least 80% of the participants, compared to only about 31% of the expected behaviours and practises. Being single [adjusted odds ratio (AOR) = 2.29; 95% CI = 1.16-4.48], having flu in the past six month (AOR = 3.24; 95% CI = 1.74-6.06), preferred self-medication (AOR = 2.07; 95% CI = 1.06-4.12) were risk factors of diarrhoea. Washing hands with water before attending to children or sick persons (AOR = 0.30; 95% CI = 0.11-0.82), washing hands with water (AOR = 0.16; 95% CI = 0.05-0.45) and water with soap (AOR = 0.29; 95% CI = 0.12-0.72) after attending to children or sick persons, and hand washing between 30 s to a minute (AOR = 0.44; 95% CI = 0.20-0.90) were protective factors against diarrhoea.

Full Text Available Abstract Background Breast screening uptake in London is below the Government's target of 70% and we investigate whether ethnicity affects this. Information on the ethnicity for the individual women invited is unavailable, so we use an area-based method similar to that routinely used to derive a geographical measure for socioeconomic deprivation. Methods We extracted 742,786 observations on attendance for routine appointments between 2004 and 2007 collected by the London Quality Assurance Reference Centre. Each woman was assigned to a lower super output (LSOA based on her postcode of residence. The proportions of the ethnic groups within each LSOA are known, so that the likelihood of a woman belonging to White, Black and Asian groups can be assigned. We investigated screening attendance by age group, socioeconomic deprivation using the Index of Deprivation 2004 income quintile, invitation type and breast screening service. Using logistic regression analysis we calculated odds ratios for attendance based on ethnic composition of the population, adjusting for age, socioeconomic status, the invitation type and screening service. Results The unadjusted attendance odds ratios were high for the White population (OR: 3.34 95% CI [3.26-3.42] and low for the Black population (0.13 [0.12-0.13] and the Asian population (0.55 [0.53-0.56]. Multivariate adjustment reduced the differences, but the Black population remained below unity (0.47 [0.44-0.50]; while the White (1.30 [1.26-1.35] and Asian populations (1.10 [1.05-1.15] were higher. There was little difference in the attendance between age groups. Attendance was highest for the most affluent group and fell sharply with increasing deprivation. For invitation type, the routine recall was higher than the first call. There were wide variations in the attendance for different ethnic groups between the individual screening services. Conclusions Overall breast screening attendance is low in communities with

The hand hygiene technique that the World Health Organization recommends for cleansing hands with soap and water or alcohol-based handrub consists of 7 poses. We used an automated training system to improve clinicians' hand hygiene technique and test whether this affected hospitalwide hand hygiene compliance. Seven hundred eighty-nine medical and nursing staff volunteered to participate in a self-directed training session using the automated training system. The proportion of successful first attempts was reported for each of the 7 poses. Hand hygiene compliance was collected according to the national requirement and rates for 2011-2014 were used to determine the effect of the training system on compliance. The highest pass rate was for pose 1 (palm to palm) at 77% (606 out of 789), whereas pose 6 (clean thumbs) had the lowest pass rate at 27% (216 out of 789). One hundred volunteers provided feedback to 8 items related to satisfaction with the automated training system and most (86%) expressed a high degree of satisfaction and all reported that this method was time-efficient. There was no significant change in compliance rates after the introduction of the automated training system. Observed compliance during the posttraining period declined but increased to 82% in response to other strategies. Technology for training clinicians in the 7 poses played an important education role but did not affect compliance rates. Crown Copyright © 2015. Published by Elsevier Inc. All rights reserved.

2018-05-17

Sport and exercise participation exert a positive effect on numerous aspects of individuals' health. Although sport and exercise leaders have generally been observed to play a key role in shaping group members' behavior, our understanding of their impact on group members' attendance in sport and exercise sessions is limited. To address this, and building on promising findings in other domains, we examined the associations between perceptions of sport and exercise leaders' engagement in social identity leadership, group identification, and attendance. A sample of 583 participants from sports teams (n = 307) and exercise groups (n = 276) completed questionnaires measuring identity leadership, group identification, and attendance. Analyses demonstrated that perceptions of leader engagement in social identity leadership were positively associated with members' group identification, and that this in turn was positively associated with their attendance in either a sports group or an exercise group. Moreover, there was a significant indirect effect for perceptions of leader engagement in identity leadership on group members' attendance through their greater identification with these groups. Findings highlight the importance of considering the impact sport and exercise leaders have on group members' attendance and suggest that leaders who represent, advance, create, and embed a shared sense of identity (ie, a shared sense of "us") among attendees can promote participation in sport and exercise. © 2018 The Authors.

Irwin, Nigel; Burnett, Kathryn M; McCarron, Paul A

2018-03-01

As the higher education (HE) classroom begins to adopt newer internet-based technologies, the relationship between attendance and performance needs to be re-evaluated, particularly for professional degree courses such as pharmacy. In the present study, we aimed to establish if an association exists between attendance at all timetabled classes and academic performance, in a Clinical Pharmacology and Therapeutics (CPT) module, as part of the Master of Pharmacy (MPharm) degree course at Ulster University. Data on attendance, final examination and coursework performance were collected over two academic years (2013-14 and 2014-15) of the CPT module at Ulster. In total 67 students were analysed. The MPharm degree at Ulster University implements an attendance policy, both as a pastoral support tool and to reinforce the need for professional conduct as a pharmacist. Student (2013-14 and 2014-15, n = 35 and 32, respectively) attendance on the module across both year groups was approximately 80%. We observed positive, and statistically significant relationships between attendance and performance on the examination, and especially in the coursework elements of the module. Student failure (below 40%) in the final examination was linked to attendance below an 80% threshold in nine of 12 cases. Reasons for not attending class varied, but illness was unquestionably the most commonly cited extenuation. Taken together, these data confirm a convincing association between student attendance and academic achievement. Our studies promote the use of attendance monitoring policies for professional degree courses such as pharmacy. Copyright © 2017 Elsevier Inc. All rights reserved.

Church Attendance and Religious Experience

Full Text Available Previous studies have shown that gender may moderate the relationship between religiousness and mental health in most countries, but few studies have been conducted in Norway and Denmark. This study examined gender differences in religious experiences and church attendance as predictors of existential well-being among 295 women and 233 men from the general Norwegian population. Analyses showed that the structural equation models for women and men did not differ significantly on the global level. The models for women and men, however, showed different patterns. Among men, church attendance and negative religious experiences predicted existential well-being; among women, positive and negative religious experiences were related to existential well-being, but church attendance was not. The present findings suggest that men may benefit more from active religiousness, whereas women may benefit more from affective religiousness. Comparing these results with research in other cultural contexts, we find that different operationalizations of church attendance yield the same types of patterns across cultural contexts. Consequently, the benefits of religiousness may be similar for women and men irrespective of cultural context.

Recommended disease prevention behaviors of hand washing, hygienic hand drying, and covering one's mouth and nose in a hygienic manner when coughing and sneezing appear to be simple behaviors but continue to be a challenge to successfully promote and sustain worldwide. We conducted a qualitative inquiry to better understand current hand drying behaviors associated with activities of daily living, and mouth and nose covering practices, among Kenyans. We conducted 7 focus group discussions; 30 in-depth interviews; 10 structured household observations; and 75 structured observations in public venues in the urban area of Kisumu; rural communities surrounding Kisumu; and a peri-urban area outside Nairobi, Kenya. Using a grounded theory approach, we transcribed and coded the narrative data followed by thematic analysis of the emergent themes. Hand drying, specifically on a clean towel, was not a common practice among our participants. Most women dried their hands on their waist cloth, called a leso, or their clothes whether they were cooking, eating or cleaning the nose of a young child. If men dried their hands, they used their trousers or a handkerchief. Children rarely dried their hands; they usually just wiped them on their clothes, shook them, or left them wet as they continued with their activities. Many people sneezed into their hands and wiped them on their clothes. Men and women used a handkerchief fairly often when they had a runny nose, cold, or the flu. Most people coughed into the air or their hand. Drying hands on dirty clothes, rags and lesos can compromise the benefits of handwashing. Coughing and sneezing in to an open hand can contribute to spread of disease as well. Understanding these practices can inform health promotion activities and campaigns for the prevention and control of diarrheal disease and influenza.

The Health Service Executive (HSE) highlights the need for effective patient throughput and management, whilst providing appropriate staffing and therapeutic interventions. It acknowledges that patient need is integral to the development of a nurse led service and advocates planning staffing levels to reflect arrival times of patients. An observational study of all patients who presented to the emergency department in July 2005 and February 2006 was undertaken (n=7768). The study identified 1577 patients suitable for treatment by the Advanced Nurse Practitioner (ANP) in these two months, which represents 20% of all patient attendances to the ED in this time period. A data collection tool was devised collectively by the ANPs to identify appropriate patients. The findings of the study revealed that 73% of patients suitable for the ANP service presented between the hours of 0800 and 2000, of which 54% attended between 0800 and 1600 h. Sunday emerged as the busiest day in July 2005 whereas Monday was found to be the busiest day in February 2006. Friday was found to be consistently busy for both months.

The association between asthma and swimming pool attendance has not been demonstrated and currently there are conflicting results. In order to clarify the association between asthma diagnosis in children and swimming pool attendance, and to assess the consistency of the available epidemiological studies, we completed a literature analysis on the relationship between the exposure to disinfection by-products in indoor swimming pools during childhood and asthma diagnosis. Following the Meta-analysis of Observational Studies in Epidemiology (MOOSE) and Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) criteria, a systematic review and meta-analysis was performed by searching MEDLINE via PubMed, TOXNET, and Scopus databases (from inception to 20 April 2015) using the key word "Asthma" together with "swimming pool", "disinfection by-products", "indoor air pollution" and "children". Inclusion criteria were: English language, a complete analytic study design involving a cohort of children (0-16 years), a well-defined definition of exposure, and the presence of data on effect and variance. Studies on in vivo, in vitro or professional and accidental exposure were excluded. After a screening process, seven reports (n = 5851 subjects) were included out of a total of 2928 references. The reported OR of the association between swimming pool attendance and asthma prevalence ranged from 0.58 to 2.30. The present meta-analysis failed to identify a significant difference in asthma development between children attending swimming pools and controls (OR, 1.084; 95% CI: 0.89-1.31). Swimming in childhood does not increase the likelihood of doctor-diagnosed asthma. Based on this meta-analysis review, the association of the disease with indoor pool attendance is still unclear. © 2016 Japan Pediatric Society.

The observation of UPSILON(9.5) suggests that the -onium of at least one new quark has been discovered. The production and decays of the lowest-lying vector states are discussed. Recent observations have no indications of right-handed currents in antineutrino-nucleon scattering. The properties of new states made of t (change = 2/3 or b (charge = -1/3) quarks are discussed in a model with just left-handed currents. Particular attention is paid to decay modes, production by neutrinos or antineutrinos, the analogues of anti K 0 mixing, and CP violation. (Auth.)

Grip Strength Survey Based on Hand Tool Usage

Directory of Open Access Journals (Sweden)

Erman ÇAKIT

2016-12-01

Full Text Available Hand grip strength is broadly used for performing tasks involving equipment in production and processing activities. Most professionals in this field rely on grip strength to perform their tasks. There were three main aims of this study: i determining various hand grip strength measurements for the group of hand tool users, ii investigating the effects of height, weight, age, hand dominance, body mass index, previous Cumulative Trauma Disorder (CTD diagnosis, and hand tool usage experience on hand grip strength, and iii comparing the obtained results with existing data for other populations. The study groups comprised 71 healthy male facility workers. The values of subjects’ ages was observed between 26 and 74 years. The data were statistically analyzed to assess the normality of data and the percentile values of grip strength. The results of this study demonstrate that there were no significance differences noted between dominant and non-dominant hands. However, there were highly significant differences between the CTD group and the other group. Hand grip strength for the dominant hand was positively correlated to height, weight, and body mass index, and negatively correlated to age and tool usage experience. Hand dominance, height, weight, body mass index, age and tool usage experience should be considered when establishing normal values for grip strength.

A Study on Attendance and Academic Achievement

Sund, Kristian J.; Bignoux, Stephane

In this study we attempt to answer Romer’s (1993) question: “Should attendance be mandatory?” Contrary to many existing studies, we conclude that in the case of business and management programs the answer is ‘no’. In a study of over 900 undergraduate strategy students, spanning four academic years......, we examine the link between attendance and exam results. Unlike prior research on this topic, our findings show that attendance is not the best determinant of student performance. We find instead that the best determinant of student performance for third year bachelor students is their over......-all degree classification, which we see as a proxy for academic ability. We suggest that attendance may simply be a reflection of student conscientiousness, engagement and motivation. We also challenge the assumptions about gender differences found in prior research on student attendance and student...

[Hand osteoarthritis].

Šenolt, Ladislav

Hand osteoarthritis (OA) is a common chronic disorder causing pain and limitation of mobility of affected joints. The prevalence of hand OA increases with age and more often affects females. Clinical signs obviously do not correlate with radiographic findings - symptomatic hand OA affects approximately 26 % of adult subjects, but radiographic changes can be found in up to two thirds of females and half of males older than 55 years.Disease course differ among individual patients. Hand OA is a heterogeneous disease. Nodal hand OA is the most common subtype affecting interphalangeal joints, thumb base OA affects first carpometacarpal joint. Erosive OA represents a specific subtype of hand OA, which is associated with joint inflammation, more pain, functional limitation and erosive findings on radiographs.Treatment of OA is limited. Analgesics and nonsteroidal anti-inflammatory drugs are the only agents reducing symptoms. New insights into the pathogenesis of disease should contribute to the development of novel effective treatment of hand OA.

Healthcare workers generally underestimate the role of environmental surfaces in the transmission of infection, and compliance with hand hygiene following contact with the environment is generally lower than following direct patient contact. To reduce the risk of onward transmission, healthcare workers must identify the need to wash hands with specific tasks or events. To observe the movement of staff in critical care and general wards and determine the routes most commonly travelled and the surfaces most frequently touched with and without appropriate hand hygiene. Fifty-eight 90 min sessions of unobtrusive observation were made in open bays and isolation rooms. Link analysis was used to record staff movement from one location to another as well as the frequency of motion. Hand-hygiene audits were conducted using the World Health Organization 'five moments for hand hygiene' observational tool. In critical care, the majority of movement occurred within the bed space. The bedside computer and equipment trolley were the surfaces most commonly touched, often immediately after patient contact. In the general ward, movement between bed spaces was more common and observed hand hygiene ranged from 25% to 33%. Regardless of ward type, observed hand-hygiene compliance when touching the patient immediately on entering an isolation room was less than 30%. Healthcare workers must be made aware that bacterial spread can occur even during activities of perceived low risk. Education and intervention programmes should focus on the potential contamination of ward computers, case notes and door handles. Copyright © 2013 The Healthcare Infection Society.

Attendance of a behavioural support programme facilitates smoking cessation. Disadvantaged smokers have been shown to attend less than their more affluent peers. We need to gain in-depth insight into underlying reasons for differing attendance behaviour in disadvantaged smokers, to better address this issue. This study aims to explore the underlying motivations, barriers and social support of smokers exhibiting different patterns of attendance at a free smoking cessation behavioural support programme in a disadvantaged neighbourhood of The Netherlands. In 29 smokers undertaking smoking cessation group therapy or telephone counselling in a disadvantaged neighbourhood, qualitative interviews were completed, coded and analysed. Major themes were motivations, barriers to attend and social support. Motivations and social support were analysed with reference to the self-determination theory. Two distinct patterns of attendance emerged: those who missed up to two sessions ("frequent attenders"), and those who missed more than two sessions ("infrequent attenders"). The groups differed in their motivations to attend, barriers to attendance, and in the level of social support they received. In comparison with the infrequent attenders, frequent attenders more often had intrinsic motivation to attend (e.g. enjoyed attending), and named more self-determined extrinsic motivations to attend, such as commitment to attendance and wanting to quit. Most of those mentioning intrinsic motivation did not mention a desire to quit as a motivation for attendance. No organizational barriers to attendance were mentioned by frequent attenders, such as misunderstandings around details of appointments. Frequent attenders experienced more social support within and outside the course. Motivation to attend behavioural support, as distinct from motivation to quit smoking, is an important factor in attendance of smoking cessation courses in disadvantaged areas. Some focus on increasing motivation to

Medulloblastoma (MB) is the most frequent malignant pediatric brain tumor. Current treatment includes surgery, radiation and chemotherapy. However, ongoing treatment in patients is further classified according to the presence or absence of metastasis. Since metastatic medulloblastoma are refractory to current treatments, there is need to identify novel biomarkers that could be used to reduce metastatic potential, and more importantly be targeted therapeutically. Previously, we showed that ionizing radiation-induced uPAR overexpression is associated with increased accumulation of β-catenin in the nucleus. We further demonstrated that uPAR protein act as cytoplasmic sequestration factor for a novel basic helix-loop-helix transcription factor, Hand1. Among the histological subtypes classical and desmoplastic subtypes account for the majority while large cell/anaplastic variant is most commonly associated with metastatic disease. In this present study using immunohistochemical approach and patient data mining for the first time, we demonstrated that Hand1 expression is observed to be downregulated in all the subtypes of medulloblastoma. Previously we showed that Hand1 overexpression regulated medulloblastoma angiogenesis and here we investigated the role of Hand1 in the context of Epithelial-Mesenchymal Transition (EMT). Moreover, UW228 and D283 cells overexpressing Hand1 demonstrated decreased-expression of mesenchymal markers (N-cadherin, β-catenin and SOX2); metastatic marker (SMA); and increased expression of epithelial marker (E-cadherin). Strikingly, human pluripotent stem cell antibody array showed that Hand1 overexpression resulted in substantial decrease in pluripotency markers (Nanog, Oct3/4, Otx2, Flk1) suggesting that Hand1 expression may be essential to attenuate the EMT and our findings underscore a novel role for Hand1 in medulloblastoma metastasis. - Highlights: • Hand1 expression is downregulated in Medulloblastoma. • Hand1 over expression reduce

Hand hygiene in emergency medical services.

Hospital-acquired infections (HAIs) affect millions of patients annually (World Health Organization. Guidelines on Hand Hygiene in Healthcare. Geneva: WHO Press; 2009). Hand hygiene compliance of clinical staff has been identified by numerous studies as a major contributing factor to HAIs around the world. Infection control and hand hygiene in the prehospital environment can also contribute to patient harm and spread of infections. Emergency medical services (EMS) practitioners are not monitored as closely as hospital personnel in terms of hand hygiene training and compliance. Their ever-changing work environment is less favorable to traditional hospital-based aseptic techniques and education. This study aimed to determine the current state of hand hygiene practices among EMS providers and to provide recommendations for improving practices in the emergency health services environment. This study was a prospective, observational prevalence study and survey, conducted over a 2-month period. We selected participants from visits to three selected hospital emergency departments in the mid-Atlantic region. There were two data components to the study: a participant survey and hand swabs for pathogenic cultures. This study recruited a total sample of 62 participants. Overall, the study revealed that a significant number of EMS providers (77%) have a heavy bacterial load on their hands after patient care. All levels of providers had a similar distribution of bacterial load. Survey results revealed that few providers perform hand hygiene before (34%) or in between patients (24%), as recommended by the Centers for Disease Control and Prevention guidelines. This study demonstrates that EMS providers are potential vectors of microorganisms if proper hand hygiene is not performed properly. Since EMS providers treat a variety of patients and operate in a variety of environments, providers may be exposed to potentially pathogenic organisms, serving as vectors for the exposure of

Congenital cytomegalovirus (CMV) transmission can occur when women acquire CMV while pregnant. Infection control guidelines may reduce risk for transmission. We studied the duration of CMV survival after application of bacteria to the hands and after transfer from the hands to surfaces and the effectiveness of cleansing with water, regular and antibacterial soaps, sanitizer, and diaper wipes. Experiments used CMV AD169 in saliva at initial titers of 1 × 10(5) infectious particles/ml. Samples from hands or surfaces (points between 0 and 15 min) were placed in culture and observed for at least 2 weeks. Samples were also tested using CMV real-time PCR. After application of bacteria to the hands, viable CMV was recovered from 17/20 swabs at 0 min, 18/20 swabs at 1 min, 5/20 swabs at 5 min, and 4/20 swabs at 15 min. After transfer, duration of survival was at least 15 min on plastic (1/2 swabs), 5 min on crackers and glass (3/4 swabs), and 1 min or less on metal and cloth (3/4 swabs); no viable virus was collected from wood, rubber, or hands. After cleansing, no viable virus was recovered using water (0/22), plain soap (0/20), antibacterial soap (0/20), or sanitizer (0/22). Viable CMV was recovered from 4/20 hands 10 min after diaper wipe cleansing. CMV remains viable on hands for sufficient times to allow transmission. CMV may be transferred to surfaces with reduced viability. Hand-cleansing methods were effective at eliminating viable CMV from hands.

Reports regarding hand hygiene compliance (HHC) among hospital visitors are limited. Although there is an implicit assumption that the availability of alcohol-based hand sanitizer (AHS) promotes visitor HHC, the degree of AHS use by visitors remains unclear. To assess AHS use, we observed visitor HHC and how it is affected by visual cues in a private university hospital. Using an observational controlled study, we tested 3 interventions: a desk sign mandating all visitors to use AHS, a free-standing AHS dispenser directly in front of a security desk, and a combination of a freestanding AHS dispenser and a sign. HHC was 0.52% at baseline and did not improve significantly when the desk sign was provided as a cue 0.67% (P = .753). However, HHC did improve significantly with use of the freestanding AHS dispenser (9.33%) and the sign and dispenser combination (11.67%) (P hand hygiene behavior.

2014-05-01

Hand hygiene is one of the most effective ways to prevent transmission of health care-associated infections. Electronic systems and tools are being developed to enhance hand hygiene compliance monitoring. Our systematic review assesses the existing evidence surrounding the adoption and accuracy of automated systems or electronically enhanced direct observations and also reviews the effectiveness of such systems in health care settings. We systematically reviewed PubMed for articles published between January 1, 2000, and March 31, 2013, containing the terms hand AND hygiene or hand AND disinfection or handwashing. Resulting articles were reviewed to determine if an electronic system was used. We identified 42 articles for inclusion. Four types of systems were identified: electronically assisted/enhanced direct observation, video-monitored direct observation systems, electronic dispenser counters, and automated hand hygiene monitoring networks. Fewer than 20% of articles identified included calculations for efficiency or accuracy. Limited data are currently available to recommend adoption of specific automatic or electronically assisted hand hygiene surveillance systems. Future studies should be undertaken that assess the accuracy, effectiveness, and cost-effectiveness of such systems. Given the restricted clinical and infection prevention budgets of most facilities, cost-effectiveness analysis of specific systems will be required before these systems are widely adopted.

2017-10-01

A 51-year-old man with an incomplete C6 spinal cord injury sustained 26 yrs ago attended twenty 2-hr visits over 10 wks for robot-assisted hand training driven by myoelectric pattern recognition. In each visit, his right hand was assisted to perform motions by an exoskeleton robot, while the robot was triggered by his own motion intentions. The hand robot was designed for this study, which can perform six kinds of motions, including hand closing/opening; thumb, index finger, and middle finger closing/opening; and middle, ring, and little fingers closing/opening. After the training, his grip force increased from 13.5 to 19.6 kg, his pinch force remained the same (5.0 kg), his score of Box and Block test increased from 32 to 39, and his score from the Graded Redefined Assessment of Strength, Sensibility, and Prehension test Part 4.B increased from 22 to 24. He accomplished the tasks in the Graded Redefined Assessment of Strength, Sensibility, and Prehension test Part 4.B 28.8% faster on average. The results demonstrate the feasibility and effectiveness of robot-assisted training driven by myoelectric pattern recognition after spinal cord injury.

Directory of Open Access Journals (Sweden)

Elisa De Stefani

Full Text Available The present study aimed at determining how actions executed by two conspecifics can be coordinated with each other, or more specifically, how the observation of different phases of a reaching-grasping action is temporary related to the execution of a movement of the observer. Participants observed postures of initial finger opening, maximal finger aperture, and final finger closing of grasp after observation of an initial hand posture. Then, they opened or closed their right thumb and index finger (experiments 1, 2 and 3. Response times decreased, whereas acceleration and velocity of actual finger movements increased when observing the two late phases of grasp. In addition, the results ruled out the possibility that this effect was due to salience of the visual stimulus when the hand was close to the target and confirmed an effect of even hand postures in addition to hand apparent motion due to the succession of initial hand posture and grasp phase. In experiments 4 and 5, the observation of grasp phases modulated even foot movements and pronunciation of syllables. Finally, in experiment 6, transcranial magnetic stimulation applied to primary motor cortex 300 ms post-stimulus induced an increase in hand motor evoked potentials of opponens pollicis muscle when observing the two late phases of grasp. These data suggest that the observation of grasp phases induced simulation which was stronger during observation of finger closing. This produced shorter response times, greater acceleration and velocity of the successive movement. In general, our data suggest best concatenation between two movements (one observed and the other executed when the observed (and simulated movement was to be accomplished. The mechanism joining the observation of a conspecific's action with our own movement may be precursor of social functions. It may be at the basis for interactions between conspecifics, and related to communication between individuals.

2018-04-24

Observational studies are common research strategies in hand surgery. The case-cohort design offers an efficient and resource-friendly method for risk assessment and outcomes analysis. Case-cohorts remain underrepresented in upper extremity research despite several practical and economic advantages over case-control studies. This report outlines the purpose, utility, and structure of the case-cohort design and offers a sample research question to demonstrate its value to risk estimation for adverse surgical outcomes. The application of well-designed case-cohort studies is advocated in an effort to improve the quality and quantity of observational research evidence in hand and upper extremity surgery.

The hands of "blast" resulting from the handling of unstable explosives. Their repercussion is functional and vital in trauma patients. The authors report their experience of care from the hands of blast in precarious health situation. Between 2001 and 2012, 33 hand blasts were supported in 30 injured civilians and military, received emergency, during and after armed conflict. Two women (6.7%) and 28 men (93.3%) were received, including four teenagers (13.3%) and 26 adults (86.7%). During the war, 15 officers weapon (50%) and three civilians (10%) underwent surgery, or 60% of hand injuries. In peacetime, civilians were mostly operated in 33.3% of cases, against 6.7% of cases of agents' weapon. Nineteen hands blast (57.6%) were observed during the war and 14 in peacetime, or 42.4% of cases. The average age was 25.2 years, with extremes of 12 and 50 years. Thirteen left hands (39.4%) and 20 right hands (60.6%) were operated. The lesion concerned all the anatomical structures of the hand. It was unilateral in 27 cases (81.9%) and bilateral in three cases (9.1%). Three types of hand trauma were observed and were as follows: trauma patients with injuries of the hand (18.2%), trauma of severe and isolated proximal hand or finger amputations (75.7%), and trauma of the hand without apparent seriousness (6.1%). The associated lesion was eye (one case), chest (one case), abdominal (five cases). Debridement was performed immediate emergency (93.9%) and delayed (6.1%). The treatment was surgical hemostasis, made mainly of amputations (69.7%) and regularization of digital stumps (12.1%). The repair was performed in 18.2% of cases. One death has been reported in a polytrauma patient with chest blast. Blast injuries of the hand are common in times of war in armed agents. The young people, manual workers and children are paying a heavy price in peacetime. As land mines which affect feet, instable hand grenades are left exposed in nature.

Two complementary approaches to right-handed currents

Gemmler, Katrin M.

2012-01-01

Flavour observables impose strong constraints on models of new physics. We study whether right-handed currents can provide a realistic extension to the Standard Model. We analyse two complementary models. These setups lead to new flavour violating interactions in the right-handed sector. We first consider a bottom-up approach assuming a left-right symmetric flavour group broken only by the Yukawa couplings. In this model the vertical stroke V ub vertical stroke problem can be solved. Secondly we study the Left-Right Model. We perform a comprehensive numerical analysis, including all known experimental constraints from ΔF=2 observables and the decay B →X s γ simultaneously. We observe that there exist regions in parameter space in accordance with the all data. In this model all flavour anomalies can be resolved except the vertical stroke V ub vertical stroke problem.

Rural/Nonrural Differences in College Attendance Patterns.

Byun, Soo-Yong; Irvin, Matthew J; Meece, Judith L

Using data from the National Education Longitudinal Study of 1988, this study documented college attendance patterns of rural youth in terms of the selectivity of first postsecondary institution of attendance, the timing of transition to postsecondary education, and the continuity of enrollment. The study also examined how these college attendance patterns among rural students differed from those among their non-rural counterparts and which factors explained these rural/nonrural differences. Results showed that rural youth were less likely than their nonrural counterparts to attend a selective institution. In addition, rural youth were more likely to delay entry to postsecondary education, compared to their urban counterparts. Finally, rural students were less likely than their urban counterparts to be continuously enrolled in college. Much of these rural/nonrural disparities in college attendance patterns were explained by rural/nonrural differences in socioeconomic status and high school preparation. Policy implications, limitations of the study, and future research directions are also discussed.

Construction workers are at risk of developing occupational contact dermatitis. Gloves, when used properly, may protect against chemicals and coarse materials. We investigated the prevalence and determinants of contact dermatitis in a population of Dutch construction workers and aimed at validating questionnaire items on hand hygiene. A cross-sectional study was conducted at 13 construction sites, yielding data of 177 subjects (95% response rate). A questionnaire covering questions on hand hygiene and contact dermatitis symptoms was used. Agreement between workplace observations and a number of questionnaire items was assessed by calculating Cohen's kappa. Log-binomial regression analysis was used to assess the association between contact dermatitis and various hand hygiene-related determinants. The 1-year prevalence of self-reported contact dermatitis in our study sample was 46.9%. Multiple regression analysis showed a positive association with difficulties with hand cleaning (prevalence ratio [PR]: 1.26, 95% confidence interval [CI]: 1.05-1.52), hand contamination at the end of the working day (PR: 2.30, 95% CI: 1.14-4.65), and intensive hand cream use (PR: 2.07, 95% CI: 1.42-3.01). Observations of hand contamination, glove use, and glove types were found to agree well with the self-reported data from the questionnaire (Cohen's kappa's 0.75, 0.97, and 0.88). Self-reported contact dermatitis prevalence in construction workers was high and related to hand hygiene. A strong agreement was found between workplace observations and self-reported questionnaire data. © The Author 2014.

The observation of gamma (9.5) suggests that the -onium of at least one new quark has been discovered. The production and decays of the lowest-lying vector states is discussed. Recent observations have no indications of right-handed currents in antineutrino-nucleon scattering. The properties of new states made of t (charge =/sup 2 ///sub 3/) or b (charge=-/sup 1///sub 3/) quarks in a model with just left-handed currents are considered. Particular attention is paid to decay modes, production by neutrinos or antineutrinos, the analogues of K/sub 0/-K/sub 0/ mixing, and CP violation. (40 refs).

Do young people attending addiction services differ from those attending youth mental health services?

2010-07-01

We aimed to describe and compare the self-reported substance use, psychopathology and psychosocial morbidity in adolescents attending two adolescent outpatient services, a triage-based mental health service and an engagement-focused addiction service in Auckland, New Zealand. A naturalistic cross-section of 131 (addiction service = 67, mental health service = 64) 14-18-year-old boys and girls attending each service completed a standardised screening and assessment instrument, the Drug Use Screening Inventory-Revised. The Drug Use Screening Inventory-Revised measures self-reported problems across 10 domains of functioning, including substance use, behaviour, psychiatric symptoms and school and family functioning. Descriptive statistics were used to provide an overview of the self-reported morbidity in each group and t-tests were used to determine differences between the two groups. Adolescents attending the addiction service reported significantly more problems with substance use, school performance and peer relationships than those attending the mental health service. There was no significant difference in reported psychiatric symptoms, behavioural problems, social competency, health problems, family problems, difficulties in work functioning or leisure time between the two groups. Young people presenting to engagement-focused substance use services report similar difficulties to those at mental health services across most areas of psychosocial functioning. Addiction services may require equivalent staffing expertise and workforce development to that in mental health to effectively meet young people's needs.

Functional Anatomy of Writing with the Dominant Hand

While writing performed by any body part is similar in style, indicating a common program, writing with the dominant hand is particularly skilled. We hypothesized that this skill utilizes a special motor network supplementing the motor equivalence areas. Using functional magnetic resonance imaging in 13 normal subjects, we studied nine conditions: writing, zigzagging and tapping, each with the right hand, left hand and right foot. We identified brain regions activated with the right (dominant) hand writing task, exceeding the activation common to right-hand use and the writing program, both identified without right-hand writing itself. Right-hand writing significantly differed from the other tasks. First, we observed stronger activations in the left dorsal prefrontal cortex, left intraparietal sulcus and right cerebellum. Second, the left anterior putamen was required to initiate all the tested tasks, but only showed sustained activation during the right-hand writing condition. Lastly, an exploratory analysis showed clusters in the left ventral premotor cortex and inferior and superior parietal cortices were only significantly active for right-hand writing. The increased activation with right-hand writing cannot be ascribed to increased effort, since this is a well-practiced task much easier to perform than some of the other tasks studied. Because parietal-premotor connections code for particular skills, it would seem that the parietal and premotor regions, together with basal ganglia-sustained activation likely underlie the special skill of handwriting with the dominant hand.

Raspberry Pi is a cheap mini-computer that officially runs on a Linux distribution Operating System (OS) such as Raspbian. It has many input and output mechanisms simulating a computer which make it useful replacement for a computer system. SimpleCV, an open source python-based image processing software and Telegram, a popular social application provide API that allow communication trough a device such as Raspberry Pi. Combining these two, an electronic attendance has been developed using open source basis, and the electronic attendance also provide enhancement of current system that is to record the person face and sending information through Telegram application. The methodology include gathering requirements on remaining system and test it on Linux which will discuss further. This project is serve as a prototype for enhancement of current Commersial Of The Shelf (COTS) electronic attendance that only record ID of the attendees. In the future, the electronic attendance can be enhanced with many features and should be make in-a-box for commercialization. (author)

Effect of ant attendance by Monomorium minimum (Buckley) (Hymenoptera: Formicidae) on predation and parasitism of the soybean aphid Aphis glycines Matsumura (Hemiptera: Aphididae).

Ant attendance is known to affect the population dynamics of aphids and may increase or decrease aphid populations through stimulation, predation, or protection. In this study, we performed a series of laboratory experiments to examine the effects of ant attendance on populations of the soybean aphid Aphis glycines. Aphid colonies were exposed to the predators Harmonia axyridis (Coccinellidae) and Orius insidiosus (Anthocoridae) and a parasitoid Aphidius colemani (Aphidiidae) in the presence and absence of attending Monomorium minimum (Formicidae). We also tested for direct effects of ant attendance in the absence of natural enemies. Ants attending soybean aphid populations were observed harassing or killing O. insidiosus and H. axyridis. Attendance interfered with both predator species, resulting in reduced predation and an increase in aphid numbers up to 10-fold in the presence of ants. Ants were not observed directly interfering with the parasitoid A. colemani, but the number of parasitized aphids was higher in aphid colonies that were left unattended by ants.

The objective of the study was to determine whether a simulation-based educational program would improve residents' and attending physicians' performance in a simulated shoulder dystocia. Seventy-one obstetricians participated in an unanticipated simulated shoulder dystocia, an educational debriefing session, and a subsequent shoulder dystocia simulation. Each simulation was scored, based on standardized checklists for 4 technical maneuvers and 6 communication tasks, by 2 physician observers. Paired Student t tests were used for analysis. Forty-three attendings and 28 residents participated. Residents showed significant improvement in mean maneuver (3.3 +/- 0.9 vs 3.9 +/- 0.4, P = .001) and communication (3.5 +/- 1.2 vs 4.9 +/- 1.0, P < .0001) scores after simulation training. Attending physicians' communication (3.6 +/- 1.6 vs 4.9 +/- 1.1, P < .0001) scores were significantly improved after training. Our program improved physician performance in the management of simulated shoulder dystocia deliveries. Obstetric emergency simulation training can improve physicians' communication skills, at all levels of training, and should be incorporated into labor and delivery quality improvement measures.

The Project "Vision through the hands" was performed by the Altino Ventura Foundation, with the purpose of investigating the present child situation with multiple disabilities in the state of Pernambuco, Brazil. Birth and social conditions, social problems, and difficulty in accessing the specialized services were evaluated, aiming to collect relevant data with the goal of posterior implantation of a specialized diagnosis and treatment center. Ophthalmologic care and proper treatment were offered. Three hundred and nine children from five reference institutions in disabilities were attended, on six non consecutive days. All cases underwent ophthalmologic examinations and parent interviews. During the waiting time between the ophthalmologic visits and parent interviews the patients performed activities with artists. A multidisciplinary team of 31 professionals was available. According to parent information 83.1% of the patients were considered included in the society and only 45.4% attended school (normal or special). The difficulty to get access to ophthalmologic service was reported by 51.1%. Two hundred and seventy children with multiple disabilities were identified, 154 (56.2%) of whom underwent an ophthalmologic examination for the first time, and 33.0% had low visual acuity (inferior to 20/60 Snellen). The most frequent diagnoses were: refraction error, strabismus, ambliopia, alterations of optic nerve (glaucoma and atrophy), and cataract. Eighty-four glasses were prescribed. This project was pioneer in the region, allowing to obtain the information about important problems regarding multiple disabilities, and making possible ophthalmologic care and specialized treatment to the children.

The experience of being a traditional midwife: relationships with skilled birth attendants.

Science.gov (United States)

Dietsch, Elaine

2010-01-01

This article focuses on an unexpected finding of a research project which explored the experience of being a traditional midwife. The unexpected finding was that traditional midwives often perceive skilled (professional) birth attendants to be abusive of both them and the women who are transferred to hospital for emergency obstetric care. Eighty-four traditional midwives in the Western Province of Kenya were interviewed individually or in groups with a Bukusu/Kiswahili/English-speaking interpreter. Interviews were audiotaped and the English components were transcribed verbatim. Interview transcripts and observations were thematically analysed. A minority of relationships between traditional midwives and skilled birth attendants were based on mutual respect and collaborative practice. However, the majority of encounters with skilled birth attendants were perceived by the traditional midwives to be abusive for them and the women requiring emergency obstetric care. In the interests of improving health outcomes for women and their newborns, interpersonal skills, including maintaining respectful communication and relationships must be a core competency for all caregivers. Providing opportunities for reciprocal learning and strategies to enhance relationships between traditional midwives and skilled birth attendants are recommended. Current global strategies to reduce maternal and newborn mortality by increasing the number of women birthing with a skilled (professional) birth attendant in an enabling environment may be limited while the reasons for traditional midwives being the caregiver of choice for the majority of women living in areas such as Western Kenya remain unaddressed.

Where There Are (Few) Skilled Birth Attendants

2011-01-01

Recent efforts to reduce maternal mortality in developing countries have focused primarily on two long-term aims: training and deploying skilled birth attendants and upgrading emergency obstetric care facilities. Given the future population-level benefits, strengthening of health systems makes excellent strategic sense but it does not address the immediate safe-delivery needs of the estimated 45 million women who are likely to deliver at home, without a skilled birth attendant. There are currently 28 countries from four major regions in which fewer than half of all births are attended by skilled birth attendants. Sixty-nine percent of maternal deaths in these four regions can be attributed to these 28 countries, despite the fact that these countries only constitute 34% of the total population in these regions. Trends documenting the change in the proportion of births accompanied by a skilled attendant in these 28 countries over the last 15-20 years offer no indication that adequate change is imminent. To rapidly reduce maternal mortality in regions where births in the home without skilled birth attendants are common, governments and community-based organizations could implement a cost-effective, complementary strategy involving health workers who are likely to be present when births in the home take place. Training community-based birth attendants in primary and secondary prevention technologies (e.g. misoprostol, family planning, measurement of blood loss, and postpartum care) will increase the chance that women in the lowest economic quintiles will also benefit from global safe motherhood efforts.

The leading hand in bimanual activities - A search for more valid handedness items.

Science.gov (United States)

Olsson, Bo; Kirchengast, Sylvia

2016-11-01

The aim of this pilot study is to test a new approach to handedness assessment based on the concept of the leading hand. A well-established graphomotor performance test of handedness (H-D-T) and a new test according on the concept of the leading hand were undertaken by 41 Viennese schoolchildren between 6 and 8 years of age. The new test is based on in vivo observations of bimanual activities. In detail the test battery consisted of 8 fine motor leading hand items. Participants had to open and close four small objects (one tube, three small bottles) in order to observe twisting movements and four small objects (2 matchboxes, 2 small brushes) in order to observe back-and-forth movements. It turned out that the leading hand does not correlate with the hand dominance in a graphomotor test to the degree that the handedness in unimanual items has been found to do and that right leading hand scores in bimanual items are encountered significantly less often than right hand scores in a graphomotor test. The findings of the present study suggest that tests of the leading hand in vivo may contribute to a higher validity of the assessment of handedness in examinations of the lateralization of higher cortical functions.

the other hand, traditional birth attendants have not been integrated within the local health system and still appear to undertake clandestine deliveries in some rural areas. The prominent role of traditional birth attendants in childbirth during the conflicts in Burundi and northern Uganda has been dwindling in the post-conflict era. Traditional birth attendants can still play an important role in facilitating facility and skilled attended births if appropriately integrated with the local health system.

2015-01-01

Our aim was to examine the rates and predictors of father attendance at nurse home visits in replication sites of the Nurse-Family Partnership (NFP). Early childhood programs can facilitate father involvement in the lives of their children, but program improvements require an understanding of factors that predict father involvement. The sample consisted of 29,109 low-income, first-time mothers who received services from 694 nurses from 80 sites. We conducted mixed-model multiple regression analyses to identify population, implementation, site, and nurse influences on father attendance. Predictors of father attendance included a count of maternal visits (B = 0.12, SE = 0.01, F = 3101.77), frequent contact between parents (B = 0.61, SE = 0.02, F = 708.02), cohabitation (B = 1.41, SE = 0.07, F = 631.51), White maternal race (B = 0.77, SE = 0.06, F = 190.12), and marriage (B = 0.42, SE = 0.08, F = 30.08). Random effects for sites and nurses predicted father-visit participation (2.7 & 6.7% of the variance, respectively), even after controlling for population sociodemographic characteristics. These findings suggest that factors operating at the levels of sites and nurses influence father attendance at home visits, even after controlling for differences in populations served. Further inquiry about these influences on father visit attendance is likely to inform program-improvement efforts. PMID:25521707

Off-hours medical care in hospitals is provided by residents, while attendings on call are available for assistance. This study evaluated the gap between residents' expectations and professional guidelines' requirements of attendings on call and what actually occurs during night shifts, while comparing surgical and medical specialties. Two questionnaires based on professional guidelines were filled by residents. The first queried about residents' expectations of attendings on call, and the second asked about communication with the attendings during actual night shifts. While 91 (100%) of residents expected the attending on call to be available by phone during the shift, only 44 (48%) expected the attending to initiate contact, and only 17 (19%) expected the attending to visit the ward or emergency department (ED) without being requested to do so. In 127 shifts (84%), some form of communication occurred. Residents called their attendings during 105 shifts (70%). However, attendings initiated contact with residents at the beginning or during the shift in only 67 (44%) and 62 (41%) shifts, respectively, and initiated a visit to the ward/ED during the shift in only 41 cases (27%). Surgical attendings initiated contact in these three ways significantly more frequently than medical attendings [21 (28%) versus 46 (61%), 20 (26%) versus 42 (56%) and 4 (5%) versus 37 (50%), respectively; P communication during night shifts between residents and attendings occurs in most shifts, attendings initiate far less contact with residents than is required by the guidelines. © 2013 John Wiley & Sons Ltd.

Two complementary approaches to right-handed currents

Energy Technology Data Exchange (ETDEWEB)

Gemmler, Katrin M.

2012-04-17

Flavour observables impose strong constraints on models of new physics. We study whether right-handed currents can provide a realistic extension to the Standard Model. We analyse two complementary models. These setups lead to new flavour violating interactions in the right-handed sector. We first consider a bottom-up approach assuming a left-right symmetric flavour group broken only by the Yukawa couplings. In this model the vertical stroke V{sub ub} vertical stroke problem can be solved. Secondly we study the Left-Right Model. We perform a comprehensive numerical analysis, including all known experimental constraints from {Delta}F=2 observables and the decay B {yields}X{sub s}{gamma} simultaneously. We observe that there exist regions in parameter space in accordance with the all data. In this model all flavour anomalies can be resolved except the vertical stroke V{sub ub} vertical stroke problem.

This study investigated the effects of hand paddles, parachute and hand paddles plus parachute on the inter-limb coordination of butterfly swimming. Thirteen male swimmers were evaluated in four random maximal intensity conditions: without equipment, with hand paddles, with parachute and with hand paddles + parachute. Arm and leg stroke phases were identified by 2D video analysis to calculate the total time gap (T1: time between hands' entry in the water and high break-even point of the first undulation; T2: time between the beginning of the hand's backward movement and low break-even point of the first undulation; T3: time between the hand's arrival in a vertical plane to the shoulders and high break-even point of the second undulation; T4: time between the hand's release from the water and low break-even point of the second undulation). The swimming velocity was reduced and T1, T2 and T3 increased in parachute and hand paddles + parachute. No changes were observed in T4. Total time gap decreased in parachute and hand paddles + parachute. It is concluded that hand paddles do not influence the arm-to-leg coordination in butterfly, while parachute and hand paddles + parachute do change it, providing a greater propulsive continuity.

Good hand hygiene compliance is essential to prevent nosocomial infections in healthcare settings. Direct observation of hand hygiene compliance is the gold standard but is time consuming. An electronic dispenser with built-in wireless recording equipment allows continuous monitoring of its usage. The purpose of this study was to monitor the use of alcohol-based hand rub dispensers with a built-in electronic counter in a neonatal intensive care unit (NICU) setting and to determine compliance with hand hygiene protocols by direct observation. A one-year observational study was conducted at a 27 bed level III NICU at a university hospital. All healthcare workers employed at the NICU participated in the study. The use of bedside dispensers was continuously monitored and compliance with hand hygiene was determined by random direct observations. A total of 258,436 hand disinfection events were recorded; i.e. a median (interquartile range) of 697 (559-840) per day. The median (interquartile range) number of hand disinfection events performed per healthcare worker during the day, evening, and night shifts was 13.5 (10.8 - 16.7), 19.8 (16.3 - 24.1), and 16.6 (14.2 - 19.3), respectively. In 65.8% of the 1,168 observations of patient contacts requiring hand hygiene, healthcare workers fully complied with the protocol. We conclude that the electronic devices provide useful information on frequency, time, and location of its use, and also reveal trends in hand disinfection events over time. Direct observations offer essential data on compliance with the hand hygiene protocol. In future research, data generated by the electronic devices can be supplementary used to evaluate the effectiveness of hand hygiene promotion campaigns.

Archer, M S; Elgar, M A

2003-09-01

Many forensically important calliphorids, sarcophagids and muscids (Diptera) oviposit or larviposit on corpses only during the early stages of decomposition, yet individuals may attend bodies throughout decay. A field study was conducted to investigate how patterns of carcass use and attendance by some fly species are affected by decomposition. Five fly traps were placed in the forest and baited with whole, fresh piglet carcasses. Piglets decomposed in traps throughout the experiment, and all were skeletonized within 6 days. Flies were trapped at both early and late decomposition stages, and the species and population structures of trap catches were compared. More flies attended carcasses early rather than late in decay. For all species, flies attending early were mainly gravid females, but few gravid females attended late in decay. No females ovi- or larviposited late in decay, whereas females of all fly species deposited offspring early in decay. The number of males trapped of each species correlated positively with the number of females with eggs at early development stages. Observations were made of fly predation by European wasps Vespula germanica Fabricius (Hymenoptera, Vespidae) and jumper ants Myrmecia pilosula Smith (Hymenoptera, Formicidae) throughout the experiment. There was a higher risk for smaller fly species of being killed following predator attack. Ants and wasps attacked smaller fly species, whereas only wasps attacked larger fly species.

Though hand hygiene is an important method of preventing healthcare-associated infection, we found suboptimal hand hygiene adherence among healthcare workers in 4 diverse Japanese hospitals (adherence rates of 11%-25%). Our goal was to assess multimodal hand hygiene intervention coupled with a contest to improve hand hygiene adherence. A total of 3 to 4 inpatient wards in 3 Japanese hospitals. Pre-post intervention study. The intervention was a multimodal hand hygiene intervention recommended by the World Health Organization that was tailored to each facility. The hospital with the highest adherence after the intervention was given $5000 US dollars and a trophy, provided by an American coinvestigator unaffiliated with any of the Japanese hospitals. We tracked hand hygiene adherence rates before patient contact for each unit and hospital and compared these to pre-intervention adherence rates. We observed 2982 postintervention provider-patient encounters in 10 units across 3 hospitals. Hand hygiene adherence rates were improved overall after the intervention (18% pre- to 33% postintervention; P hand hygiene rates among Japanese healthcare workers. Given the overall low rates, however, further improvement is necessary. © 2015 Society of Hospital Medicine.

Tongue corticospinal modulation during attended verbal stimuli: priming and coarticulation effects.

Humans perceive continuous speech through interruptions or brief noise bursts cancelling entire phonemes. This robust phenomenon has been classically associated with mechanisms of perceptual restoration. In parallel, recent experimental evidence suggests that the motor system may actively participate in speech perception, even contributing to phoneme discrimination. In the present study we intended to verify if the motor system has a specific role in speech perceptual restoration as well. To this aim we recorded tongue corticospinal excitability during phoneme expectation induced by contextual information. Results showed that phoneme expectation determines an involvement of the individual's motor system specifically implicated in the production of the attended phoneme, exactly as it happens during actual listening of that phoneme, suggesting the presence of a speech imagery-like process. Very interestingly, this motoric phoneme expectation is also modulated by subtle coarticulation cues of which the listener is not consciously aware. Present data indicate that the rehearsal of a specific phoneme requires the contribution of the motor system exactly as it happens during the rehearsal of actions executed by the limbs, and that this process is abolished when an incongruent phonemic cue is presented, as similarly occurs during observation of anomalous hand actions. We propose that altogether these effects indicate that during speech listening an attentional-like mechanism driven by the motor system, based on a feed-forward anticipatory mechanism constantly verifying incoming information, is working allowing perceptual restoration.

Kingston, Liz M; O'Connell, Nuala H; Dunne, Colum P

2018-04-01

In Ireland, the setting for this study, the national prevalence rate of health care-associated infection (HCAI) in acute-care facilities is 5.2%. Hand hygiene and in particular hand rubbing using alcohol-based hand rub (ABHR) is highly efficacious in preventing HCAI transmission. Yet, compliance among healthcare professionals is sub-optimal. Less is known about the practices of nursing and medical students and no study comparing practices among these groups in Ireland was found. Hence, the aim of this study was to provide insight into the current hand hygiene and hand rubbing practices of nursing and medical students in Ireland and, by doing so, contribute to the broader understanding of this topic. This observational study employed a cross-sectional, self-reported design. An electronically administered questionnaire was sent to all nursing and medical students from one university. Data were analysed using appropriate software. The response rate was 37% (323/872). Higher compliance with the World Health Organisation 'my five moments for hand hygiene' model was reported among nursing students (NS) than medical students (MS), with scope for improvement in both disciplines identified. Hand hygiene compliance was highest after body fluid exposure (99.5% NS, 91% MS) and lowest after touching a patient's surroundings (61.5% NS, 57.5% MS). Attitudes towards hand rubbing were largely positive in both disciplines. 16% of NS were not aware of the clinical contraindications to ABHR use, compared to 45% of MS. 9% of NS did not know when to use soap and water and when to use ABHR, compared to 36% of MS. In contrast, more medical students (46%) than nursing students (22%) were routinely using alcohol-based hand rub for decontamination of hands as recommended. Results suggest scope to review current hand hygiene curricula focusing on the knowledge gaps, the practice deficits and the barriers to ABHR usage identified. Copyright © 2018 Elsevier Ltd.

2009-01-01

Hand prostheses that are currently available on the market are used by amputees to only a limited extent, partly because of lack of sensory feedback from the artificial hand. We report a pilot study that showed how amputees can experience a robot-like advanced hand prosthesis as part of their own body. We induced a perceptual illusion by which touch applied to the stump of the arm was experienced from the artificial hand. This illusion was elicited by applying synchronous tactile stimulation to the hidden amputation stump and the robotic hand prosthesis in full view. In five people who had had upper limb amputations this stimulation caused referral touch sensation from the stump to the artificial hand, and the prosthesis was experienced more like a real hand. We also showed that this illusion can work when the amputee controls the movements of the artificial hand by recordings of the arm muscle activity with electromyograms. These observations indicate that the previously described "rubber hand illusion" is also valid for an advanced hand prosthesis, even when it has a robotic-like appearance.

Computer program for the automated attendance accounting system

Science.gov (United States)

Poulson, P.; Rasmusson, C.

1971-01-01

The automated attendance accounting system (AAAS) was developed under the auspices of the Space Technology Applications Program. The task is basically the adaptation of a small digital computer, coupled with specially developed pushbutton terminals located in school classrooms and offices for the purpose of taking daily attendance, maintaining complete attendance records, and producing partial and summary reports. Especially developed for high schools, the system is intended to relieve both teachers and office personnel from the time-consuming and dreary task of recording and analyzing the myriad classroom attendance data collected throughout the semester. In addition, since many school district budgets are related to student attendance, the increase in accounting accuracy is expected to augment district income. A major component of this system is the real-time AAAS software system, which is described.

Attendance at NHS mandatory training sessions.

Brand, Darren

2015-02-17

To identify factors that affect NHS healthcare professionals' attendance at mandatory training sessions. A quantitative approach was used, with a questionnaire sent to 400 randomly selected participants. A total of 122 responses were received, providing a mix of qualitative and quantitative data. Quantitative data were analysed using statistical methods. Open-ended responses were reviewed using thematic analysis. Clinical staff value mandatory training sessions highly. They are aware of the requirement to keep practice up-to-date and ensure patient safety remains a priority. However, changes to the delivery format of mandatory training sessions are required to enable staff to participate more easily, as staff are often unable to attend. The delivery of mandatory training should move from classroom-based sessions into the clinical area to maximise participation. Delivery should be assisted by local 'experts' who are able to customise course content to meet local requirements and the requirements of different staff groups. Improved arrangements to provide staff cover, for those attending training, would enable more staff to attend training sessions.

Major sporting events may influence attendance levels at hospital emergency departments (ED). Previous research has focussed on the impact of single games, or wins/losses for specific teams/countries, limiting wider generalisations. Here we explore the impact of the Euro 2016 football championships on ED attendances across four participating nations (England, France, Northern Ireland, Wales), using a single methodology. Match days were found to have no significant impact upon daily ED attendances levels. Focussing upon hourly attendances, ED attendances across all countries in the four hour pre-match period were statistically significantly lower than would be expected (OR 0.97, 95% CI 0.94-0.99) and further reduced during matches (OR 0.94, 95% CI 0.91-0.97). In the 4 hour post-match period there was no significant increase in attendances (OR 1.01, 95% CI 0.99-1.04). However, these impacts were highly variable between individual matches: for example in the 4 hour period following the final, involving France, the number of ED attendances in France increased significantly (OR 1.27, 95% CI 1.13-1.42). Overall our results indicate relatively small impacts of major sporting events upon ED attendances. The heterogeneity observed makes it difficult for health providers to predict how major sporting events may affect ED attendances but supports the future development of compatible systems in different countries to support cross-border public health surveillance.

To describe self-reported practices and assess knowledge and attitudes regarding hand hygiene among healthcare workers in a rural Indian teaching hospital. A rural teaching hospital and its associated medical and nursing colleges in the district of Ujjain, India. The study population consisted of physicians, nurses, teaching staff, clinical instructors and nursing students. Self-administered questionnaires based on the World Health Organization Guidelines on Hand Hygiene in Healthcare were used. Out of 489 healthcare workers, 259 participated in the study (response rate = 53%). The proportion of healthcare workers that reported to 'always' practice hand hygiene in the selected situations varied from 40-96% amongst categories. Reported barriers to maintaining good hand hygiene were mainly related to high workload, scarcity of resources, lack of scientific information and the perception that priority is not given to hand hygiene, either on an individual or institutional level. Previous training on the topic had a statistically significant association with self-reported practice (p = 0.001). Ninety three per cent of the respondents were willing to attend training on hand hygiene in the near future. Self-reported knowledge and adherence varied between situations, but hand hygiene practices have the potential to improve if the identified constraints could be reduced. Future training should focus on enhancing healthcare workers' knowledge and understanding regarding the importance of persistent practice in all situations.

The single most critical intervention to improve maternal and neonatal survival is to ensure that a competent health worker with midwifery skills is present at every birth, and transport is available to a referral facility for obstetric care in case of an emergency. This study aims to describe changes in percentage of skilled birth attendants in Ghana and to identify causes of the observed changes as well as the contribution of different categories of mother's characteristics to these changes. This study uses two successive nationally representative household surveys: the 2003 and 2008 Ghana Demographic and Health Surveys (GDHS). The two datasets have comparable information on household characteristics and skilled attendants at birth at the time of the survey. The 2003 GDHS database includes information on 6,251 households and 3639 live births in the five years preceding the survey, whereas the 2008 GDHS database had information on11, 778 households and 2909 live births in the five years preceding the survey. A decomposition approach was used to explain the observed change in percentage of skilled birth attendants. Random-effects generalized least square regression was used to explore the effect of changes in population structure in respect of the mother's characteristics on percentage of skilled birth attendants over the period. Overall, the data showed absolute gain in the proportion of births attended by a health professional from 47.1% in 2003 to 58.7% in 2008, which represents 21.9% of gap closed to reach universal coverage. The increase in skilled birth attendants was found to be caused by changes in general health behaviour. The gain is regardless of the mother's characteristics. The structural change in the proportion of births in respect of birth order and mother's education had little effect on the change in percentage of skilled birth attendants. Improvement in general health behaviour can potentially contribute to an accelerated increase in proportion

Search for right-handed currents in muon decay

International Nuclear Information System (INIS)

Carr, J.

The experiment is motivated by the recent interest in left-right symmetric theories based on the gauge group SU(2)sub(R) x SU(2)sub(L) x U(1). Such theories are left-right symmetric at the Lagrangian level but account for the apparently maximal parity violation at present energies by assuming that the right-handed gauge boson Wsub(R) has acquired, through spontaneous symmetry breaking, a mass larger than its left-handed counterpart Wsub(L). A search is made for deviations from maximal parity violation by observing the muon decay rate when the decay positron is emitted with momentum close to the kinematic limit and opposite to the muon spin direction. This decay rate approaches zero at the kinematic limit for purely left-handed W's (V-A) but is large for right-handed W's (V+A). From the data, bounds on the right-handed gauge boson mass and also on non-(V or A) couplings can be set. (author)

We discuss the phenomenology of right-handed charged currents in the framework of the Standard Model Effective Field Theory, in which they arise due to a single gauge-invariant dimension-six operator. We study the manifestations of the nine complex couplings of the W to right-handed quarks in collider physics, flavor physics, and low-energy precision measurements. We first obtain constraints on the couplings under the assumption that the right-handed operator is the dominant correction to the Standard Model at observable energies. We subsequently study the impact of degeneracies with other Beyond-the-Standard-Model effective interactions and identify observables, both at colliders and low-energy experiments, that would uniquely point to right-handed charged currents.

Hand biometric recognition based on fused hand geometry and vascular patterns.

Science.gov (United States)

Park, GiTae; Kim, Soowon

2013-02-28

A hand biometric authentication method based on measurements of the user's hand geometry and vascular pattern is proposed. To acquire the hand geometry, the thickness of the side view of the hand, the K-curvature with a hand-shaped chain code, the lengths and angles of the finger valleys, and the lengths and profiles of the fingers were used, and for the vascular pattern, the direction-based vascular-pattern extraction method was used, and thus, a new multimodal biometric approach is proposed. The proposed multimodal biometric system uses only one image to extract the feature points. This system can be configured for low-cost devices. Our multimodal biometric-approach hand-geometry (the side view of the hand and the back of hand) and vascular-pattern recognition method performs at the score level. The results of our study showed that the equal error rate of the proposed system was 0.06%.

To compare surgical strategies, complications, and outcomes of posterior corrective surgery for AIS between junior attending surgeons and senior attending surgeons. According to experience level of operation surgeons, the patients were assigned to 2 groups. Group A was the "junior surgeon" group. Group B was the "senior surgeon" group. The following parameters were compared between the 2 groups: age, sex, diagnosis, hospital of record, surgeon experience level, type of instrumentation, type of screws, estimated blood loss, duration of surgery, length of fusion, correction techniques, main curve correction, and thoracic kyphosis correction. A total of 132 patients with AIS were included in group A, whereas 207 were in group B. The translational technique was used more often in group A (P Senior surgeons used more monoaxial screws than junior surgeons (P senior group (P senior group had significant better correction rates of severe main curve (>70°) and thoracic kyphosis than the junior group (P Senior attending surgeons outperformed junior surgeons in blood loss control, thoracic kyphosis correction, and correction of severe curves.

Full Text Available Abstract Today students class attendance is become more important part for any organizationsinstitutions. The conventional method of taking attendance by calling names or signing on paper is very time consuming and insecure hence inefficient. This paper presents the manual students attendance management into computerized system for convenience or data reliability. So the system is developed by the integration of ubiquitous computing systems into classroom for managing the students attendance using RFID and fingerprint reader. The system is designed to implement an attendance management system based on RFID and fingerprint reader which students need to use their student identification card ID and their finger ID to success the attendance where only authentic student can be recorded the attendance during the class. In this system passive RFID tag and reader pairs are used to register the student ID cards individually and fingerprint reader is used for attendance. This system takes attendance electronically with the help of the RFID and finger print device and the records of the attendance are stored in a database. Students roll call percentages and their details are easily seenvia Graphical User Interface GUI. This system will have the required databases for students attendance teachers subjects and students details. This application is implemented by Microsoft Visual Studio and Microsoft SQL Server as IDE. C language is used to implement this system.

Effects of hand gestures on auditory learning of second-language vowel length contrasts.

2014-12-01

Research has shown that hand gestures affect comprehension and production of speech at semantic, syntactic, and pragmatic levels for both native language and second language (L2). This study investigated a relatively less explored question: Do hand gestures influence auditory learning of an L2 at the segmental phonology level? To examine auditory learning of phonemic vowel length contrasts in Japanese, 88 native English-speaking participants took an auditory test before and after one of the following 4 types of training in which they (a) observed an instructor in a video speaking Japanese words while she made syllabic-rhythm hand gesture, (b) produced this gesture with the instructor, (c) observed the instructor speaking those words and her moraic-rhythm hand gesture, or (d) produced the moraic-rhythm gesture with the instructor. All of the training types yielded similar auditory improvement in identifying vowel length contrast. However, observing the syllabic-rhythm hand gesture yielded the most balanced improvement between word-initial and word-final vowels and between slow and fast speaking rates. The overall effect of hand gesture on learning of segmental phonology is limited. Implications for theories of hand gesture are discussed in terms of the role it plays at different linguistic levels.

To identify omissions in hand hygiene practice and glove use among hospital workers in Hong Kong. Hospital-acquired infection is the commonest complication affecting hospitalised patients. Even though research evidence suggests that hand hygiene and proper glove use are the most important ways to prevent the spread of disease and infection, compliance with both are reported to be unacceptably low. An observational study of hospital workers in one acute and two convalescence and rehabilitation hospitals in Hong Kong was conducted. The participating clinical areas included the medical and surgical wards, accident and emergency department and intensive care unit. Hand hygiene practice and glove use amongst 206 hospital health and support workers, stratified according to years of working experience, were observed. The number of observed episodes for hand hygiene was 1037 and for glove use 304. Compliance with hand hygiene was 74.7% and with glove use 72.4%. In approximately two-third of episodes, participants washed their hands after each patient contact; though, 78.5% failed to rub their hands together vigorously for at least 15 seconds. The major break in compliance with glove use was failure to change gloves between procedures on the same patient. In 28.6% of observed glove use episodes, participants did not wear gloves during procedures that exposed them to blood, body fluids, excretion, non-intact skin or mucous membranes. Significant differences in performance scores on antiseptic hand rub were found between the two types of hospital and on glove use between the three groups of work experience: ≤ 5, 6-10, >10 years. Education and reinforcement of proper hand hygiene practice and glove use among hospital health and support workers is needed. © 2011 Blackwell Publishing Ltd.

BACKGROUND Hand hygiene is the core element of infection prevention and control. The optimal hand-hygiene gesture, however, remains poorly defined. OBJECTIVE We aimed to evaluate the influence of hand-rubbing duration on the reduction of bacterial counts on the hands of healthcare personnel (HCP). METHODS We performed an experimental study based on the European Norm 1500. Hand rubbing was performed for 10, 15, 20, 30, 45, or 60 seconds, according to the WHO technique using 3 mL alcohol-based hand rub. Hand contamination with E. coli ATCC 10536 was followed by hand rubbing and sampling. A generalized linear mixed model with a random effect on the subject adjusted for hand size and gender was used to analyze the reduction in bacterial counts after each hand-rubbing action. In addition, hand-rubbing durations of 15 and 30 seconds were compared to assert non-inferiority (0.6 log10). RESULTS In total, 32 HCP performed 123 trials. All durations of hand rubbing led to significant reductions in bacterial counts (Phand rubbing were not significantly different from those obtained after 30 seconds. The mean bacterial reduction after 15 seconds of hand rubbing was 0.11 log10 lower (95% CI, -0.46 to 0.24) than after 30 seconds, demonstrating non-inferiority. CONCLUSIONS Hand rubbing for 15 seconds was not inferior to 30 seconds in reducing bacterial counts on hands under the described experimental conditions. There was no gain in reducing bacterial counts from hand rubbing longer than 30 seconds. Further studies are needed to assess the clinical significance of our findings.

Mechanisms of action imitation were examined. Previous studies have suggested that success or failure of imitation is determined at the point of observing an action. In other words, cognitive processing after observation is not related to the success of imitation; 20 university students participated in each of three experiments in which they observed a series of object manipulations consisting of four elements (hands, tools, object, and end points) and then imitated the manipulations. In Experiment 1, a specific intially observed element was color coded, and the specific manipulated object at the imitation stage was identically color coded; participants accurately imitated the color coded element. In Experiment 2, a specific element was color coded at the observation but not at the imitation stage, and there were no effects of color coding on imitation. In Experiment 3, participants were verbally instructed to attend to a specific element at the imitation stage, but the verbal instructions had no effect. Thus, the success of imitation may not be determined at the stage of observing an action and color coding can provide a clue for imitation at the imitation stage.

Full Text Available It has been shown that mental rotation of objects and human body parts is processed differently in the human brain. But what about body parts belonging to other primates? Does our brain process this information like any other object or does it instead maximize the structural similarities with our homologous body parts? We tried to answer this question by measuring the manual reaction time (MRT of human participants discriminating the handedness of drawings representing the hands of four anthropoid primates (orangutan, chimpanzee, gorilla, and human. Twenty-four right-handed volunteers (13 males and 11 females were instructed to judge the handedness of a hand drawing in palm view by pressing a left/right key. The orientation of hand drawings varied from 0º (fingers upwards to 90º lateral (fingers pointing away from the midline, 180º (fingers downwards and 90º medial (finger towards the midline. The results showed an effect of rotation angle (F(3, 69 = 19.57, P < 0.001, but not of hand identity, on MRTs. Moreover, for all hand drawings, a medial rotation elicited shorter MRTs than a lateral rotation (960 and 1169 ms, respectively, P < 0.05. This result has been previously observed for drawings of the human hand and related to biomechanical constraints of movement performance. Our findings indicate that anthropoid hands are essentially equivalent stimuli for handedness recognition. Since the task involves mentally simulating the posture and rotation of the hands, we wondered if "mirror neurons" could be involved in establishing the motor equivalence between the stimuli and the participants' own hands.

Psychotherapy nonattendance is a costly and pervasive problem. While prior research has identified stable patient-level predictors of attendance, far less is known about dynamic (i.e., time-varying) factors. Identifying dynamic predictors can clarify how clinical states relate to psychotherapy attendance and inform effective "just-in-time" interventions to promote attendance. The present study examines whether daily mood, as measured by responses to automated mobile phone-based text messages, prospectively predicts attendance in group cognitive-behavioral therapy (CBT) for depression. Fifty-six Spanish-speaking Latino patients with elevated depressive symptoms (46 women, mean age=50.92years, SD=10.90years), enrolled in a manualized program of group CBT, received daily automated mood-monitoring text messages. Patients' daily mood ratings, message response rate, and delay in responding were recorded. Patients' self-reported mood the day prior to a scheduled psychotherapy session significantly predicted attendance, even after controlling for patients' prior attendance history and age (OR=1.33, 95% CI [1.04, 1.70], p=.02). Positive mood corresponded to a greater likelihood of attendance. Our results demonstrate the clinical utility of automated mood-monitoring text messages in predicting attendance. These results underscore the value of text messaging, and other mobile technologies, as adjuncts to psychotherapy. Future work should explore the use of such monitoring to guide interventions to increase attendance, and ultimately the efficacy of psychotherapy. Copyright © 2017. Published by Elsevier Ltd.

Park, GiTae; Kim, Soowon

2013-01-01

A hand biometric authentication method based on measurements of the user's hand geometry and vascular pattern is proposed. To acquire the hand geometry, the thickness of the side view of the hand, the K-curvature with a hand-shaped chain code, the lengths and angles of the finger valleys, and the lengths and profiles of the fingers were used, and for the vascular pattern, the direction-based vascular-pattern extraction method was used, and thus, a new multimodal biometric approach is proposed. The proposed multimodal biometric system uses only one image to extract the feature points. This system can be configured for low-cost devices. Our multimodal biometric-approach hand-geometry (the side view of the hand and the back of hand) and vascular-pattern recognition method performs at the score level. The results of our study showed that the equal error rate of the proposed system was 0.06%. PMID:23449119

Stackelroth, Jenny; Sinnott, Michael; Shaban, Ramon Z

2015-09-01

Existing research has consistently demonstrated poor compliance by health care workers with hand hygiene standards. This study examined the extent to which incorrect hand hygiene occurred as a result of the inability to easily distinguish between different hand hygiene solutions placed at washbasins. A direct observational method was used using ceiling-mounted, motion-activated video camera surveillance in a tertiary referral emergency department in Australia. Data from a 24-hour period on day 10 of the recordings were collected into the Hand Hygiene-Technique Observation Tool based on Feldman's criteria as modified by Larson and Lusk. A total of 459 episodes of hand hygiene were recorded by 6 video cameras in the 24-hour period. The observed overall rate of error in this study was 6.2% (27 episodes). In addition an overall rate of hesitation was 5.8% (26 episodes). There was no statistically significant difference in error rates with the 2 hand washbasin configurations. The amelioration of causes of error and hesitation by standardization of the appearance and relative positioning of hand hygiene solutions at washbasins may translate in to improved hand hygiene behaviors. Placement of moisturizer at the washbasin may not be essential. Crown Copyright © 2015. Published by Elsevier Inc. All rights reserved.

Guideline Implementation: Hand Hygiene.

Goldberg, Judith L

2017-02-01

Performing proper hand hygiene and surgical hand antisepsis is essential to reducing the rates of health care-associated infections, including surgical site infections. The updated AORN "Guideline for hand hygiene" provides guidance on hand hygiene and surgical hand antisepsis, the wearing of fingernail polish and artificial nails, proper skin care to prevent dermatitis, the wearing of jewelry, hand hygiene product selection, and quality assurance and performance improvement considerations. This article focuses on key points of the guideline to help perioperative personnel make informed decisions about hand hygiene and surgical hand antisepsis. The key points address the necessity of keeping fingernails and skin healthy, not wearing jewelry on the hands or wrists in the perioperative area, properly performing hand hygiene and surgical hand antisepsis, and involving patients and visitors in hand hygiene initiatives. Perioperative RNs should review the complete guideline for additional information and for guidance when writing and updating policies and procedures. Copyright © 2017 AORN, Inc.

OBJECTIVE: To evaluate the possible contribution of alcohol to presentation of elderly subjects at a hospital accident and emergency (A&E) department. METHODS: 105 patients aged 70 years and over who attended the department were interviewed by a single observer using a structured questionnaire based on previously validated general population surveys. Details of alcohol consumption within the previous 24 hours were recorded. Usual consumption of alcohol in the preceding 12 months was estimated by the quantity frequency method. Alcohol dependence was screened for by the CAGE questionnaire. An assessment of disability was made using the Barthel index. Breath alcohol was measured. RESULTS: In only 2% of attenders was alcohol thought to be a contributory factor. Breath alcohol measurements were technically unsatisfactory in this age group. Regular drinkers were functionally and socially more independent than non-regular drinkers. Drinking patterns in this age group may partly be determined by the physical ability to obtain alcohol. CONCLUSIONS: Alcohol was not found to be a major factor in A&E attendance in elderly people. PMID:8832344

There is consensus that best clinical practice for dual diagnosis (DD) is integrated mental health and substance use treatment augmented with Alcoholics Anonymous (AA) attendance. This is the first quantitative review of the direction and magnitude of the association between AA attendance and alcohol abstinence for DD patients. A systematic literature search (1993-2017) identified 22 studies yielding 24 effect sizes that met our inclusion criteria (8,075 patients). Inverse-variance weighting of correlation coefficients (r) was used to aggregate sample-level findings and study aims were addressed using random and mixed effect models. Sensitivity and publication bias analyses were conducted to assess the likelihood of bias in the overall estimate of AA-related benefit. AA exposure and abstinence for DD patients were significantly and positively associated (r w =.249; 95% CI.203-.293; Tau=.097). There was also significant heterogeneity in the distribution of effect sizes, (Q(23)=90.714, pAA-related benefit did not differ between 6 (k=7) and 12 (k=12) month follow-up, (Q=.068, pAA benefit was not adversely or substantively impacted by pooling RCT and observational samples (Q=.763, pAA (Q=.023, pAA) is common and, in many cases, DD patients who attend AA will report higher rates of alcohol abstinence relative to DD patients who do not attend AA.

Inequalities in Dental Attendance throughout the Life-course

Science.gov (United States)

2012-01-01

The purpose of this study was to identify socio-economic inequalities in regular dental attendance throughout the life-course. The analyses relied on data from SHARE (waves 1 to 3 of the Survey of Health, Ageing, and Retirement in Europe), which includes retrospective information on life-course dental attendance of 26,525 persons currently aged 50 years or greater from 13 European countries (Austria, Poland, Spain, Italy, the Netherlands, Belgium, Greece, the Czech Republic, France, Denmark, Switzerland, Germany, and Sweden). Inequalities in dental attendance were assessed by means of Concentration Indices. Socio-economic disparities in regular dental attendance were identified as early as childhood. Moreover, higher educational attainment resulted in increased probabilities of regular dental attendance throughout subsequent life-years in all nations. In most countries, inequality levels remained relatively inelastic throughout the life-course. These findings suggest that a considerable proportion of inequalities in dental care use is already established at childhood and persists throughout the life-course. PMID:22699676

Wright, Michael; Hall, Jane; van Gool, Kees; Haas, Marion

2018-05-01

Australians can seek general practice care from multiple general practitioners (GPs) in multiple locations. This provides high levels of patient choice but may reduce continuity of care. The aim of this study was to estimate the prevalence of attendance at multiple general practices in Australia, and identify patient characteristics associated with multiple practice attendances. A cross-sectional survey of 2477 Australian adults was conducted online in July 2013. Respondents reported whether they had attended more than one general practice in the past year, and whether they had a usual general practice and GP. Demographic information, health service use and practice characteristics were also obtained from the survey. Over one-quarter of the sample reported attending more than one practice in the previous year. Multiple practice attendance is less common with increasing age, and less likely for survey respondents from regional Australia, compared with respondents from metropolitan areas. Multiple practice attenders are just as likely as single practice attenders to have a usual GP. A significant proportion of general practice care is delivered away from usual practices. This may have implications for health policy, in terms of continuity and quality of primary care.

Religious attendance after elevated depressive symptoms: is selection bias at work?

Directory of Open Access Journals (Sweden)

Lloyd Balbuena

2014-03-01

Full Text Available In an attempt to determine if selection bias could be a reason that religious attendance and depression are related, the predictive value of elevated depressive symptoms for a decrease in future attendance at religious services was examined in a longitudinal panel of 1,673 Dutch adults. Religious attendance was assessed yearly over five years using the single question, “how often do you attend religious gatherings nowadays?” Depressive symptoms were assessed four times within the first year using the Depression subscale of the Brief Symptom Inventory. Logistic regression models of change in attendance were created, stratifying by baseline attendance status. Attenders who developed elevated symptoms were less likely to subsequently decrease their attendance (relative risk ratio: 0.55, 95% CI [0.38–0.79] relative to baseline as compared to those without elevated symptoms. This inverse association remained significant after controlling for health and demographic covariates, and when using multiply imputed data to account for attrition. Non-attenders were unlikely to start attending after elevated depressive symptoms. This study provides counter evidence against previous findings that church attenders are a self-selected healthier group.

Caudwell, KM and Keatley, DA. The effect of men's body attitudes and motivation for gym attendance. J Strength Cond Res 30(9): 2550-2556, 2016-The current study integrates men's body attitudes with implicitly and explicitly measured motivation to investigate the role of these factors in predicting gym attendance. Male participants (N = 99) who regularly attended a gym were recruited to participate in an online questionnaire. Participants completed implicit and explicit measures of motivation, explicitly measured men's body attitudes, and reported the average number of gym visits per week. Attitudes related to body fat and explicitly measured autonomous motivation significantly predicted typical gym attendance. Implicitly measured motivation significantly and negatively predicted gym attendance. Results indicate some support for a dual-systems account of gym attendance. Men's body attitudes and autonomous motivation influences gym attendance; however, implicitly measured motivation showed antagonistic effects. Although individuals may explicitly state their autonomous motivation for gym attendance, attendance may also be influenced at the explicit level. Health and fitness professionals may improve gym attendance by focusing on people's reasons for attending a gym, facilitating autonomous motivation in clients, and minimizing the influence of controlled reasons for exercise.

2004-11-01

Health care-associated infections persist as a major problem in most neonatal intensive care units. Hand hygiene has been singled out as the most important measure in preventing hospital-acquired infection. However, hand hygiene compliance among health care workers (HCWs) remains low. The objective of this study was to assess the frequency and nature of patient contacts in neonatal intensive care units and observe the compliance and technique of hand hygiene among HCWs before and after the implementation of a multimodal intervention program. The nature and frequency of patient contacts, the hand hygiene compliance, and hand-washing techniques of HCWs were observed unobtrusively to reflect the baseline compliance and to investigate factors for noncompliance. The intervention consisted of problem-based and task-orientated hand hygiene education, enhancement of minimal handling protocol and clustering of nursing care, liberal provision of alcohol-based hand antiseptic, improvement in hand hygiene facilities, ongoing regular hand hygiene audit, and implementation of health care-associated infection surveillance. The observational study was repeated 6 months after the completion of the intervention program, which extended over 1-year period. Overall hand hygiene compliance increased from 40% to 53% before patient contact and 39% to 59% after patient contact. More marked improvement was observed for high-risk procedures (35%-60%). The average number of patient contacts also decreased from 2.8 to 1.8 per patient per hour. There was improvement in most aspects of hand-washing technique in the postintervention stage. The health care-associated infection rate decreased from 11.3 to 6.2 per 1000 patient-days. A problem-based and task-orientated education program can improve hand hygiene compliance. Enhancement of minimal handling and clustering of nursing procedures reduced the total patient contact episodes, which could help to overcome the major barrier of time constraints

Full Text Available Objective: to identify the adherence of health professionals of an intensive care unit to the five moments for hand hygiene. Method: cross-sectional analytical study with a quantitative approach, based on secondary data from a database of a hospital infection control service at an institution in southern Brazil. A total of 793 observations were analyzed from July to December 2012. Results: hand washing was not performed in 446 (56.2% of the observations, and the adherence rate was 43.7%. The greatest adherence to hand hygiene was among the physiotherapists (53.5% and the lowest adherence was among the nursing staff (29.2%. The indications with the lowest adherence rates to hand hygiene were "before touching the patient" (18.4% and "before aseptic procedure" (20.9%. Conclusion: we conclude that adherence to hand washing does not comply with the national and international guidelines, especially when we consider the current scenario of growing infections caused by multidrug-resistant microorganisms.

Constraint Study for a Hand Exoskeleton: Human Hand Kinematics and Dynamics

Fai Chen Chen

2013-01-01

Full Text Available In the last few years, the number of projects studying the human hand from the robotic point of view has increased rapidly, due to the growing interest in academic and industrial applications. Nevertheless, the complexity of the human hand given its large number of degrees of freedom (DoF within a significantly reduced space requires an exhaustive analysis, before proposing any applications. The aim of this paper is to provide a complete summary of the kinematic and dynamic characteristics of the human hand as a preliminary step towards the development of hand devices such as prosthetic/robotic hands and exoskeletons imitating the human hand shape and functionality. A collection of data and constraints relevant to hand movements is presented, and the direct and inverse kinematics are solved for all the fingers as well as the dynamics; anthropometric data and dynamics equations allow performing simulations to understand the behavior of the finger.

In the department of engineering, students are required to fulfil at least 80 percent of class attendance. Conventional method requires student to sign his/her initial on the attendance sheet. However, this method is prone to cheating by having another student signing for their fellow classmate that is absent. We develop our hypothesis according to a verse in the Holy Qur’an (95:4), “We have created men in the best of mould”. Based on the verse, we believe each psychological characteristic of human being is unique and thus, their speech characteristic should be unique. In this paper we present the development of speech biometric-based attendance system. The system requires user’s voice to be installed in the system as trained data and it is saved in the system for registration of the user. The following voice of the user will be the test data in order to verify with the trained data stored in the system. The system uses PSD (Power Spectral Density) and Transition Parameter as the method for feature extraction of the voices. Euclidean and Mahalanobis distances are used in order to verified the user’s voice. For this research, ten subjects of five females and five males were chosen to be tested for the performance of the system. The system performance in term of recognition rate is found to be 60% correct identification of individuals.

Our aim was to examine the internet health seeking behaviour of parents attending a general paediatric outpatient clinic. For this purpose, the proportion of parents going online to obtain child health information, the most commonly used online resources, and factors having an influence on internet usage were identified. This cross-sectional observational study was conducted at a general paediatric outpatient clinic in Vienna, Austria. Data collection was done by means of an anonymous questionnaire containing 14 items. A total number of 500 questionnaires were collected. Among parents visiting the outpatient clinic, 94.4% use the internet to obtain child health information in general and 21% to be informed about the reason for consultation. Most commonly used online resources are Google (91.4%), websites run by doctors (84.8%), Wikipedia (84.7%), health portals (76.4%), the outpatient clinic's homepage (76.4%), as well as health forums and communities (61.9%). Younger parents (p = 0.022) and parents of younger children (p parents with different completed educational levels (mothers: p = 0.078; fathers: p = 0.388) do not differ in this behaviour. Important reasons for high internet use might be the inexperience of young parents regarding child health as well as the frequent infections, vaccinations, and preventive check-ups which are associated with young age of children. In contrast to former findings relating to health seekers in general, internet usage of parents is independent of their sex and educational level. © The Author(s) 2015.

To investigate the effect of hand immersion duration on manipulative ability and tactile sensitivity. Individuals in maritime settings often work with hands that have been immersed in water. Although research has shown that hand immersion duration differentially impacts skin adhesion and tactile sensitivity, the effect of hand immersion on manipulative ability has not been directly tested. Given how critical manipulative ability is for the safety and performance of those working at sea, the effect of hand immersion duration on manual performance was investigated. Tests of manipulative ability (Purdue Pegboard, Grooved Pegboard, reef knot untying) and tactile sensitivity (Touch-Test) were completed following no-exposure, short-exposure, and long-exposure hand immersions in thermoneutral water. Compared to the no immersion condition, the Purdue Pegboard performance was reduced in both immersion conditions (short exposure, -11%; long exposure, -8%). A performance decrement was only observed in the short exposure condition (+15% in time to complete task) for the reef knot untying task. There were no statistical differences in the Grooved Pegboard or Touch-Test scores between exposure conditions. Immersing the hands in water decreases manipulative ability except for when object properties reduce the slipperiness between the hand and object. Manual performance in a wet environment may be conserved by designing tools and objects with edges and textures that can offset the slipperiness of wet hands. To maintain safety, the time requirements for working with wet hands needs to be considered.

2014-08-01

Adequate hand hygiene is often considered as the most effective method of reducing the rates of hospital-acquired infections, which are one of the major causes of increased cost, morbidity, and mortality in healthcare. Electronic monitoring technologies provide a promising direction for achieving sustainable hand hygiene improvement by introducing the elements of automated feedback and creating the possibility to automatically collect individual hand hygiene performance data. The results of the multiphase testing of an automated hand hygiene reminding and monitoring system installed in a complex continuing care setting are presented. The study included a baseline Phase 1, with the system performing automated data collection only, a preintervention Phase 2 with hand hygiene status indicator enabled, two intervention Phases 3 and 4 with the system generating hand hygiene reminding signals and periodic performance feedback sessions provided, and a postintervention Phase 5 with only hand hygiene status indicator enabled and no feedback sessions provided. A significant increase in hand hygiene performance observed during the first intervention Phase 3 was sustained over the second intervention Phase 4, with the postintervention phase also indicating higher hand hygiene activity rates compared with the preintervention and baseline phases. The overall trends observed during the multiphase testing, the factors affecting acceptability of the automated hand hygiene monitoring system, and various strategies of technology deployment are discussed.

The Avocado Hand

LENUS (Irish Health Repository)

Rahmani, G

2017-11-01

Accidental self-inflicted knife injuries to digits are a common cause of tendon and nerve injury requiring hand surgery. There has been an apparent increase in avocado related hand injuries. Classically, the patients hold the avocado in their non-dominant hand while using a knife to cut\\/peel the fruit with their dominant hand. The mechanism of injury is usually a stabbing injury to the non-dominant hand as the knife slips past the stone, through the soft avocado fruit. Despite their apparent increased incidence, we could not find any cases in the literature which describe the “avocado hand”. We present a case of a 32-year-old woman who sustained a significant hand injury while preparing an avocado. She required exploration and repair of a digital nerve under regional anaesthesia and has since made a full recovery.

This Point/Counterpoint discusses the long-argued debate over whether lecture attendance in dental school at the predoctoral level should be required. Current educational practice relies heavily on the delivery of content in a traditional lecture style. Viewpoint 1 asserts that attendance should be required for many reasons, including the positive impact that direct contact of students with faculty members and with each other has on learning outcomes. In lectures, students can more easily focus on subject matter that is often difficult to understand. A counter viewpoint argues that required attendance is not necessary and that student engagement is more important than physical classroom attendance. This viewpoint notes that recent technologies support active learning strategies that better engage student participation, fostering independent learning that is not supported in the traditional large lecture classroom and argues that dental education requires assimilation of complex concepts and applying them to patient care, which passing a test does not ensure. The two positions agree that attendance does not guarantee learning and that, with the surge of information technologies, it is more important than ever to teach students how to learn. At this time, research does not show conclusively if attendance in any type of setting equals improved learning or ability to apply knowledge.

Veterinary students can be exposed to environmental infectious agents in school that may include zoonotic pathogens. Encouraging effective hand hygiene can minimize the spread of zoonoses and promote public health and the One Health concept among veterinary students. The purpose of this study was to determine if a campaign could improve hand hygiene among veterinary students at extracurricular meetings serving meals. Nine Kansas State University College of Veterinary Medicine (KSU-CVM) extracurricular organizations participated in the study, sanitizer was provided at each meeting, and baseline hand-hygiene data were observed. A hand-hygiene opportunity was defined as any student observed to approach the buffet food line. Sanitizer use (yes/no) and gender (male/female) were recorded. Campaign interventions included a 3.5-minute educational video and a novel motivational poster. The video was presented to all first-year, second-year, and third-year veterinary students. Posters encouraging hand sanitization were displayed on doors and tables alongside sanitizers at each meeting. Observational hand-hygiene data were collected immediately after introduction of interventions and again 3 months later. Environmental sampling for presence of bacteria in and around meeting locations was also performed. Observed hand hygiene was lowest during baseline (11.0% ± 1.7), improved significantly post-intervention (48.8% ± 3.2), and remained improved at 3-month follow-up (33.5% ± 4.0). Females had higher probability of hand sanitizing (35.9% ± 2.2) than males (21.4% ± 2.4) (phand hygiene before meals.

To compare liquid soap versus 4% chlorhexidine gluconate in 4% alcohol for the decontamination of bare or gloved hands inoculated with an epidemic strain of Clostridium difficile. C difficile (6.7 log10 colony-forming units [CFU], 47% spores), was seeded onto bare or latex gloved hands of ten volunteers and allowed to dry. Half the volunteers initially washed with soap and half with chlorhexidine, followed by the other agent 1 week later. Cultures were done with Rodac plates at three sites on the hand: finger/thumbtips, the palmar surfaces of the fingers, and the palm. Statistical comparison was by paired Student's t test. On bare hands, soap and chlorhexidine did not differ in residual bacterial counts on the finger/thumbtips (log10 CFU, 2.0 and 2.1, P = NS) and fingers (log10 CFU, 2.4 and 2.5, P = NS). Counts were too high on bare palms to quantitate. On gloved hands, soap was more effective than chlorhexidine on fingers (log10 CFU 1.3 and 1.7, P soap wash than following chlorhexidine wash. These observations support the use of either soap or chlorhexidine as a handwash for removal of C difficile, but efficacy in the prevention of C difficile transmission must be determined by prospective clinical trials.

Effective hand hygiene is essential to prevent the spread of pathogens on produce farms and reduce foodborne illness. The U.S. Food and Drug Administration Food Safety Modernization Act Proposed Rule for Produce Safety recommends the use of soap and running water for hand hygiene of produce handlers. The use of alcohol-based hand sanitizer (ABHS) may be an effective alternative hygiene intervention where access to water is limited. There are no published data on the efficacy of either soap or ABHS-based interventions to reduce microbial contamination in agricultural settings. The goal of this study was to assess the ability of two soap-based (traditional or pumice) and two ABHS-based (label-use or two-step) hygiene interventions to reduce microbes (coliforms, Escherichia coli, and Enterococcus spp.) and soil (absorbance of hand rinsate at 600 nm [A600]) on farmworker hands after harvesting produce, compared with the results for a no-hand-hygiene control. With no hand hygiene, farmworker hands were soiled (median A600, 0.48) and had high concentrations of coliforms (geometric mean, 3.4 log CFU per hand) and Enterococcus spp. (geometric mean, 5.3 log CFU per hand) after 1 to 2 h of harvesting tomatoes. Differences in microbial loads in comparison to the loads in the control group varied by indicator organism and hygiene intervention (0 to 2.3 log CFU per hand). All interventions yielded lower concentrations of Enterococcus spp. and E. coli (P hands (P hand washing with soap at reducing indicator organisms on farmworker hands. Based on these results, ABHS is an efficacious hand hygiene solution for produce handlers, even on soiled hands.

The risks to patients from pathogens present on healthcare workers' (HCWs') hands are high; however, compliance with hand hygiene among HCWs is low. We devised a prospective intervention trial of a new hand-hygiene dispensing technology to improve HCWs' compliance with hand hygiene. Baseline hand-hygiene compliance was observed for three months before and after an intervention consisting of implementation of an electronic device that reminds people to comply with hand hygiene after restroom visits. Compliance in hand-hygiene performance after restroom visits increased among HCWs from 66% to 91% after the intervention. Copyright © 2016 The Healthcare Infection Society. Published by Elsevier Ltd.

Ali, A A; Siddig, M F

2012-11-01

To identify and understand knowledge and practice among traditional birth attendants (TBAs), a total of 111 TBAs were interviewed at Kassala, Eastern Sudan between March and April 2011. Hand-washing prior to the delivery was a universal practice but only 25.2% of the interviewed TBAs used sterilised equipment. TBAs in this study appeared to have a low level of awareness about when a mother should be referred to hospital, and lacked basic information on family planning and HIV/AIDS. None of these 111 TBAs knew or used equipment for neonatal resuscitation (such as bag, tube and mask) or knew neonatal signs that needed extra attention such as change in skin colour, weak suckling and respiratory distress, and nearly one-third (28.8%) of the respondents believed in a few days delay in milk production. Thus, substantial effort is needed to improve the knowledge and practice among TBAs in Eastern Sudan, including training programmes, and this might be the best hope to achieve the Millennium Development Goals.

Preparing a continuous tapering conical shape and maintaining the original shape of a canal are obligatory in root canal preparation. The purpose of this study was to compare the shaping performance in simulated curved canal resin blocks of the same novice dental students using hand-prepared and engine-driven nickel-titanium (NiTi) rotary ProTaper instruments in an endodontic laboratory class. Twenty-three fourth-year dental students attending China Medical University Dental School prepared 46 simulated curved canals in resin blocks with two types of NiTi rotary systems: hand and motor ProTaper files. Composite images were prepared for estimation. Material removed, canal width and canal deviation were measured at five levels in the apical 4 mm of the simulated curved canals using AutoCAD 2004 software. Data were analyzed using Wilcoxon's rank-sum test. The hand ProTaper group cut significantly wider than the motor rotary ProTaper group in the outer wall, except for the apical 0 mm point. The total canal width was cut significantly larger in the hand group than in the motor group. There was no significant difference between the two groups in centering canal shape, except at the 3 mm level. These findings show that the novice students prepared the simulated curved canal that deviated more outwardly from apical 1 mm to 4 mm using the hand ProTaper. The ability to maintain the original curvature was better in the motor rotary ProTaper group than in the hand ProTaper group. Undergraduate students, if following the preparation sequence carefully, could successfully perform canal shaping by motor ProTaper files and achieve better root canal geometry than by using hand ProTaper files within the same teaching and practicing sessions.

Student nurse absenteeism in higher education: An argument against enforced attendance.

Science.gov (United States)

Lipscomb, Martin; Snelling, Paul C

2010-08-01

Unauthorised student nurse absenteeism in higher education troubles many university lecturers. Anecdotally, absenteeism is occasionally raised as an issue by attending students who resent others "getting away" with non-attendance and some policy documents appear to suggest that attendance should be mandated. This paper argues against enforced attendance in higher education and challenges those who would mandate attendance to explain and justify their position. Drawing on a range of nursing and non-nursing material we here discuss some of the literature on attendance, absenteeism, effort or time spent in study and grade attainment. Informed by this admittedly partial review we maintain that the evidence linking grade attainment with attendance and study effort is less conclusive than intuition might initially suggest. We note that enforcing attendance apparently runs counter to important pedagogic (humanistic and androgogic) principles. We propose that responses to absenteeism cannot be separated from questions of 'harm' and we suggest that lecturers should refrain from associating non-attendance with unprofessional behaviour and poor professionalization.

The objective of this study is to describe rates of clinic attendance of youth with sickle cell disease prescribed hydroxyurea and examine potential demographic and medical factors related to consistent clinic attendance. Participants included 148 youth diagnosed with sickle cell disease and prescribed hydroxyurea during a single calendar year. Clinic attendance and potential demographic and medical factors related to attendance were extracted via systematic retrospective medical chart review. Youth attended 90.3% of scheduled appointments and 85.1% of youth attended at least 80% of scheduled clinic appointments during the study window. Adjusting for other factors, multivariate analysis revealed families with fewer children in the household, families with private insurance, youth experiencing fever, and youth not experiencing pain during the calendar year were more likely to consistently attend clinic visits. Adherence to clinic appointments is critical to optimizing health outcomes for youth with sickle cell disease and integral for adequate monitoring of youth prescribed hydroxyurea, in particular. Findings may aid providers in appropriately identifying possible barriers to clinic attendance to develop attendance promotion interventions.

Prevention of health care-associated infections starts with scrupulous hand hygiene (HH). Improving HH compliance is a major target for the World Health Organization Patient Safety Challenge and is one of The Joint Commission's National Patient Safety Goals. Yet, adherence to HH protocols is generally poor for health care professionals, despite interventions designed to improve compliance. At Tufts Medical Center (Boston), HH compliance rates were consistently low despite the presence of a traditional HH campaign that used communication and education. A comprehensive program incorporated strong commitment by hospital leadership-who were actively involved in responsibilities previously only performed by infection preventionists and quality and patient safety staff-dedication of financial resources, including securing a grant; collaborating with a private advertising firm in a marketing campaign; and employing a multifaceted approach to education, observation, and feedback. This campaign resulted in a rapid and sustained improvement in HH compliance: Compared with the mean HH compliance rate for the six months before the campaign (72%), postcampaign HH compliance (mean = 94%) was significantly greater (p marketing campaign to fit this academic medical center's particular culture, strong support from the medical center leadership, a multifaceted educational approach, and monthly feedback on HH compliance. A comprehensive campaign resulted in rapid and sustained improvement in HH compliance at an academic medical center after traditional communication and education strategies failed to improve HH performance.

Lee Ann Riesenberg

2014-11-01

Full Text Available Background: Residency stress has been shown to interfere with resident well-being and patient safety. We developed a survey research study designed to explore factors that may affect perception of a maladaptive response to stress. Methods: A 16-item survey with 12 Likert-type perception items was designed to determine how often respondents agreed or disagreed with statements regarding the resident on the trigger tape. A total of 438 respondents from multiple institutions completed surveys. Results: Attending physicians were more likely than residents to agree that the resident on the trigger tape was impaired, p<0.0001; needed to seek professional counseling, p=0.0003; should be removed from the service, p=0.002; was not receiving adequate support from the attending physician, p=0.007; and was a risk to patient safety, p=0.02. Attending physicians were also less likely to agree that the resident was a good role model, p=0.001, and that the resident should be able to resolve these issues herself/himself, p<0.0001. Conclusion: Our data suggest that resident physicians may not be able to adequately detect maladaptive responses to stress and that attending physicians may be more adept at recognizing this problem. More innovative faculty and resident development workshops should be created to teach and encourage physicians to better observe and detect residents who are displaying maladaptive responses to stress.

Rita Babeluk

Full Text Available Hand hygiene is acknowledged as the single most important measure to prevent nosocomial infections in the healthcare setting. Similarly, in non-clinical settings, hand hygiene is recognised as a key element in helping prevent the spread of infectious diseases. The aim of this study was to evaluate the efficacy of three different disinfectant hand sanitizers in reducing the burden of bacterial hand contamination in 60 healthy volunteers in a community setting, both before and after education about the correct use of hand sanitizers. The study is the first to evaluate the efficacy and ease of use of different formulations of hand rubs used by the general population. The products tested were: Sterillium (perfumed, liquid, desderman pure gel (odorless, gel and Lavit (perfumed, spray. Sterillium and desderman are EN1500 (hygienic hand rub certified products (available in pharmacy and Lavit is non EN1500 certified and available in supermarkets. The two EN1500 certified products were found to be significantly superior in terms of reducing bacterial load. desderman pure gel, Sterillium and Lavit reduced the bacterial count to 6.4%, 8.2% and 28.0% respectively. After education in the correct use of each hand rub, the bacterial load was reduced even further, demonstrating the value of education in improving hand hygiene. Information about the testers' perceptions of the three sanitizers, together with their expectations of a hand sanitizer was obtained through a questionnaire. Efficacy, followed by skin compatibility were found to be the two most important attributes of a hand disinfectant in our target group.

2016-02-25

Equipped with a third hand under their direct control, surgeons may be able to perform certain surgical interventions alone; this would reduce the need for a human assistant and related coordination difficulties. However, does human performance improve with three hands compared to two hands? To evaluate this possibility, we carried out a behavioural study on the performance of naive adults catching objects with three virtual hands controlled by their two hands and right foot. The subjects could successfully control the virtual hands in a few trials. With this control strategy, the workspace of the hands was inversely correlated with the task velocity. The comparison of performance between the three and two hands control revealed no significant difference of success in catching falling objects and in average effort during the tasks. Subjects preferred the three handed control strategy, found it easier, with less physical and mental burden. Although the coordination of the foot with the natural hands increased trial after trial, about two minutes of practice was not sufficient to develop a sense of ownership towards the third arm.

Goals We sought to identify factors associated with gastroenterology clinic attendance in an urban safety net healthcare system. Background Missed clinic appointments reduce the efficiency and availability of healthcare, but subspecialty clinic attendance among patients with established healthcare access has not been studied. Study We performed an observational study using secondary data from administrative sources to study patients referred to, and scheduled for an appointment in, the adult gastroenterology clinic serving the safety net healthcare system of San Francisco, California. Our dependent variable was whether subjects attended or missed a scheduled appointment. Analysis included multivariable logistic regression and classification tree analysis. 1,833 patients were referred and scheduled for an appointment between 05/2005 and 08/2006. Prisoners were excluded. All patients had a primary care provider. Results 683 patients (37.3%) missed their appointment; 1,150 (62.7%) attended. Language was highly associated with attendance in the logistic regression; non-English speakers were less likely than English speakers to miss an appointment (adjusted odds ratio 0.42 [0.28,0.63] for Spanish, 0.56 [0.38,0.82] for Asian language, p gastroenterology clinic appointment, not speaking English was most strongly associated with higher attendance rates. Patient related factors associated with not speaking English likely influence subspecialty clinic attendance rates, and these factors may differ from those affecting general healthcare access.

2018-04-20

Hyper-attendance is a significant problem in paediatric Primary Care clinics. The aim of our study was to analyse the level of attendance in these clinics and its relationship with certain psychosocial aspects of the families attending them. Observational descriptive study was conducted using questionnaires collected during a period of 6months, as well as recording the frequency of attendance in the previous 6months. A total of 346 questionnaires of children between 6months and 13years of age belonging to 2 urban Primary Care clinics in Madrid were completed. The raw data was analysed, and comparisons between groups and multivariate analysis were performed. The mean number of consultations in the last 6months, of the total included in the study, was 3.06 in the Primary Care centre, and 0.77 in the emergency services. It was considered over-frequent for those who had attended the Primary Care health centre 6 or more times in this period (>p90), of which there were 33 children (9.53%). In the multivariate analysis, the variables related to being frequent users of Primary Care clinics were: the presence of high level of anxiety in the parents (OR=5.50; 95%CI: 2.49-12.17, P<.0001), and the age of the children (OR=0.73; 95%CI: 0.58-0.91, P=.005). The model presented an area under the curve of 0.761 (95%CI: 0.678-0.945, P<.0001). The frequency of visits in paediatric Primary Care clinics is directly related to the high level of anxiety of the parents, and inversely to the age of the children. It would be advisable to detect and, if possible, intervene in cases of high parental anxiety in order to try to reduce the over-frequency in the paediatric primary health care. Copyright © 2018.

The sense of body ownership, i.e., the belief that a specific body part belongs to us, can be selectively impaired in brain-damaged patients. Recently, a pathological form of embodiment has been described in patients who, when the examiner's hand is located in a body-congruent position, systematically claim that it is their own hand (E+ patients). This paradoxical behavior suggests that, in these patients, the altered sense of body ownership also affects their capacity of visually discriminating the body-identity details of the own and the alien hand, even when both hands are clearly visible on the table. Here, we investigated whether, in E+ patients with spared tactile sensibility, a coherent body ownership could be restored by introducing a multisensory conflict between what the patients feel on the own hand and what they see on the alien hand. To this aim, we asked the patients to rate their sense of body ownership over the alien hand, either after segregated tactile stimulations of the own hand (out of view) and of the alien hand (visible) or after synchronous and asynchronous tactile stimulations of both hands, as in the rubber hand illusion set-up. Our results show that, when the tactile sensation perceived on the patient's own hand was in conflict with visual stimuli observed on the examiner's hand, E+ patients noticed the conflict and spontaneously described visual details of the (visible) examiner's hand (e.g., the fingers length, the nails shape, the skin color…), to conclude that it was not their own hand. These data represent the first evidence that, in E+ patients, an incongruent visual-tactile stimulation of the own and of the alien hand reduces, at least transitorily, the delusional body ownership over the alien hand, by restoring the access to the perceptual self-identity system, where visual body identity details are stored.

Objective: To investigate the clinical value of ultrasound examination of carpal canal structure in patients with mild hand-arm vibration disease. Methods: A total of 29 patients (58 wrists) with mild hand-arm vibration disease who were treated in Shenzhen Prevention and Treatment Center for Occupational Diseases from May to December, 2015 were enrolled as observation group, and 20 healthy volunteers (40 wrists) were enrolled as the control group. Color Doppler ultrasound was used to observe the morphology and echo of the median nerve in the carpal canal and 9 muscle tendons and transverse carpal ligament. The thickness of transverse carpal ligament and diameter of the median nerve at the level of the hamulus of hamate bone were measured, as well as the cross-sectional area of the median nerve at the level of pisiform bone. Results: In the 29 patients with hand-arm vibration disease patients in the observation group, 8 experienced entrapment of the median nerve in the carpal canal, among whom 5 had entrapment in both wrists; there were 13 wrists (23%) with nerve entrapment and 45 wrists (77%) without nerve entrapment. Compared with the control group, the patients with hand-arm vibration disease and nerve entrapment in the observation group showed significant thickening of the transverse carpal ligament at the level of the hamulus of hamate bone and a significant increase in the cross-sectional area of the median nerve at the level of pisiform bone ( P 0.05) . Conclusion: Ultrasound examination can clearly show the radiological changes of carpal canal contents in patients with mild hand-arm vibration disease and has a certain diagnostic value in nerve damage in patients with hand-arm vibration disease.

The growth of online shopping increases consumers' dependence on vicarious sensory experiences, such as observing others touching products in commercials. However, empirical evidence on whether observing others' sensory experiences increases purchasing intention is still scarce. In the present study, participants observed others interacting with products in the first- or third-person perspective in video clips, and their neural responses were measured with functional magnetic resonance imaging (fMRI). We investigated (1) whether and how vicariously touching certain products affected purchasing intention, and the neural correlates of this process; and (2) how visual perspective interacts with vicarious tactility. Vicarious tactile experiences were manipulated by hand actions touching or not touching the products, while the visual perspective was manipulated by showing the hand actions either in first- or third-person perspective. During the fMRI scanning, participants watched the video clips and rated their purchasing intention for each product. The results showed that, observing others touching (vs. not touching) the products increased purchasing intention, with vicarious neural responses found in mirror neuron systems (MNS) and lateral occipital complex (LOC). Moreover, the stronger neural activities in MNS was associated with higher purchasing intention. The effects of visual perspectives were found in left superior parietal lobule (SPL), while the interaction of tactility and visual perspective was shown in precuneus and precuneus-LOC connectivity. The present study provides the first evidence that vicariously touching a given product increased purchasing intention and the neural activities in bilateral MNS, LOC, left SPL and precuneus are involved in this process.

Health care-associated infection is a major cause of morbidity and mortality. Hand hygiene is regarded as an effective preventive measure. To update the review done in 2007, to assess the short and longer-term success of strategies to improve hand hygiene compliance and to determine whether a sustained increase in hand hygiene compliance can reduce rates of health care-associated infection. We conducted electronic searches of: the Cochrane Central Register of Controlled Trials; the Cochrane Effective Practice and Organisation of Care Group specialised register of trials; MEDLINE; PubMed; EMBASE; CINAHL; and the BNI. Originally searched to July 2006, for the update databases were searched from August 2006 until November 2009. Randomised controlled trials, controlled clinical trials, controlled before and after studies, and interrupted time series analyses meeting explicit entry and quality criteria used by the Cochrane Effective Practice and Organisation of Care Group were eligible for inclusion. Studies reporting indicators of hand hygiene compliance and proxy indicators such as product use were considered. Self-reported data were not considered a valid measure of compliance. Studies to promote hand hygiene compliance as part of a care bundle approach were included, providing data relating specifically to hand hygiene were presented separately. Studies were excluded if hand hygiene was assessed in simulations, non-clinical settings or the operating theatre setting. Two reviewers independently extracted data and assessed data quality. Four studies met the criteria for the review: two from the original review and two from the update. Two studies evaluated simple education initiatives, one using a randomized clinical trial design and the other a controlled before and after design. Both measured hand hygiene compliance by direct observation. The other two studies were both interrupted times series studies. One study presented three separate interventions within the

Full Text Available The present study investigated the automatic influence of perceiving a picture that indicates other’s action on one’s own task performance in terms of spatial compatibility and effector priming. Participants pressed left and right buttons with their left and right hands respectively, depending on the color of a central dot target. Preceding the target, a left or right hand stimulus (pointing either to the left or right with the index or little finger was presented. In Experiment 1, with brief presentation of the pointing hand, a spatial compatibility effect was observed: Responses were faster when the direction of the pointed finger and the response position were spatially congruent than when incongruent. The spatial compatibility effect was larger for the pointing index finger stimulus compared to the pointing little finger stimulus. Experiment 2 employed longer duration of the pointing hand stimuli. In addition to the spatial compatibility effect for the pointing index finger, the effector priming effect was observed: Responses were faster when the anatomical left/right identity of the pointing and response hands matched than when the pointing and response hands differed in left/right identity. The results indicate that with sufficient processing time, both spatial/symbolic and anatomical features of a static body part implying another’s action simultaneously influence different aspects of the perceiver’s own action. Hierarchical coding, according to which an anatomical code is used only when a spatial code is unavailable, may not be applicable if stimuli as well as responses contain anatomical features.

The Effect of Antibacterial Formula Hand Cleaners on the Elimination of Microbes on Hands

Science.gov (United States)

Coleman, J. R.

2002-05-01

: The purpose of this project is to find out which one of the antibacterial hand cleanser (antibacterial bar soap, antibacterial liquid hand soap, and liquid hand sanitizer) is more effective in eliminating microbes. If antibacterial- formula liquid hand soap is used on soiled hands, then it will be more effective in eliminating microbes. Germs are microorganisms that cause disease and can spread from person-to-person. Bacteria are a kind of microbe, an example of which is Transient Flora that is often found on hands. Hand washing prevents germs from spreading to others. During the procedure, swabs were used to take samples before and after the soiled hands had been washed with one of the antibacterial hand cleansers. Nutrient Easygel was poured into petri dishes to harden for 1 day, and then samples were swabbed on the gel. The Petri dishes were placed in an incubator for 24 hours, and then data was recorded accordingly. The antibacterial liquid hand soap was sufficient in eliminating the majority of bacteria. The hands had 65% of the bacteria on them, and after the liquid hand soap was used only 37% of the bacteria remained.

Manually recorded attendance of all the employees has produced some problems such as the data accuracy and staff performance efficiency. The objective of this research is to design and develop a software of RFID attendance system which is integrated with database system. This RFID attendance system was developed using several main components such as tags that will be used as a replacement of ID cards and a reader device that will read the information related to the employee attendance. The result of this project is a software of RFID attendance system that is integrated with the database and has a function to store the data or information of every single employee. This system has a maximum reading range of 2 cm with success probability of 1 and requires a minimum interval between readings of 2 seconds in order to achieve an optimal functionality. By using the system, the discipline attitude of the employees and also the performance of the staff will be improved instantly.

Electronic medical file exchange between on-duty care providers and the attending paediatrician: a Belgian paediatric pilot project.

2012-01-01

The authors propose the introduction of a pilot project: "paediatric core file exchange in emergencies" (PCF-EXEM) which enables the exchange of medical data between the attending paediatrician (AP), holder of the medical record, and on-duty medical units (i.e. general practitioners, paediatricians, surgeons, emergency physicians,...). This project is based on two pillars: a protected server (PCF-server) containing paediatric core files (PCF), with important clinical data that should be available for the physician in order to quickly get a clear insight into the relevant clinical medical history of the child, and secondly, the possibility to provide feedback to the attending physician about the findings recorded during the on-call duty. The permanent availability of health data on the PCF-server and the possibility to provide feedback represent together the PCF-EXEM-project. This project meets the demand of the care providers to have relevant medical information permanently available in order to guarantee high quality care in emergency situations. The frail balance between the right to informative privacy and professional confidentiality on the one hand and the right to quality health care on the other hand has been taken into account. The technical and practical feasibility of this project is described. The objectives and vision of the PCF-EXEM project are conform to Belgian legislation concerning the processing of medical data and are in line with the still under consideration European projects which are focusing on interoperability and the development of a common access control to databanks containing health data for care providers. PCF-EXEM could therefore be a model for other EU countries as well.

Ahemad, Nasir; Purkait, Ruma

2011-05-01

Stature is used for constructing a biological profile that assists with the identification of an individual. So far, little attention has been paid to the fact that stature can be estimated from hand impressions left at scene of crime. The present study based on practical observations adopted a new methodology of measuring hand length from the depressed area between hypothenar and thenar region on the proximal surface of the palm. Stature and bilateral hand impressions were obtained from 503 men of central India. Seventeen dimensions of hand were measured on the impression. Linear regression equations derived showed hand length followed by palm length are best estimates of stature. Testing the practical utility of the suggested method on latent prints of 137 subjects, a statistically insignificant result was obtained when known and estimated stature derived from latent prints was compared. The suggested approach points to a strong possibility of its usage in crime scene investigation, albeit the fact that validation studies in real-life scenarios are performed. © 2011 American Academy of Forensic Sciences.

2006-01-01

The use of hand-held cellular (mobile) phones while driving has stirred more debate, passion, and research than perhaps any other traffic safety issue in the past several years. There is ample research showing that the use of either hand-held or hands-free cellular phones can lead to unsafe driving patterns. Whether or not these performance deficits increase the risk of crash is difficult to establish, but recent studies are beginning to suggest that cellular phone use elevates crash risk. The purpose of this study was to assess changes in the rate of hand-held cellular phone use by motor-vehicle drivers on a statewide level in Michigan. This study presents the results of 13 statewide surveys of cellular phone use over a 4-year period. Hand-held cellular phone use data were collected through direct observation while vehicles were stopped at intersections and freeway exit ramps. Data were weighted to be representative of all drivers traveling during daylight hours in Michigan. The study found that driver hand-held cellular phone use has more than doubled between 2001 and 2005, from 2.7% to 5.8%. This change represents an average increase of 0.78 percentage points per year. The 5.8% use rate observed in 2005 means that at any given daylight hour, around 36,550 drivers were conversing on cellular phones while driving on Michigan roadways. The trend line fitted to these data predicts that by the year 2010, driver hand-held cellular phone use will be around 8.6%, or 55,000 drivers at any given daylight hour. These results make it clear that cellular phone use while driving will continue to be an important traffic safety issue, and highlight the importance of continued attempts to generate new ways of alleviating this potential hazard.

Garcia, Kimberly; Dowling, Donna; Mettler, Gretchen

2018-06-01

Guatemala's Maternal Mortality Rate is 65th highest in the world at 120 deaths per 100,000 births. Contributing to the problem is traditional birth attendants (TBAs) attend most births yet lack knowledge about obstetrical emergencies. Government trainings in existence since 1955 have not changed TBA knowledge. Government trainings are culturally insensitive because they are taught in Spanish with written material, even though most TBAs are illiterate and speak Mayan dialects. The purpose of the observational study was to evaluate the effect of an oral training, that was designed to be culturally sensitive in TBAs' native language, on TBAs' knowledge of obstetrical emergencies. one hundred ninety-one TBAs participated. The study employed a pretest-posttest design. A checklist was used to compare TBAs' knowledge of obstetrical emergencies before and after the training. the mean pretest score was 5.006±SD 0.291 compared to the mean posttest score of 8.549±SD 0.201. Change in knowledge was a P value of 0.00. results suggest an oral training that was designed to be culturally sensitive in the native language improved TBAs' knowledge of obstetrical emergencies. Future trainings should follow a similar format to meet the needs of illiterate audiences in remote settings. Copyright © 2018 Elsevier Ltd. All rights reserved.

The Effects of Social Influence on Nurses' Hand Hygiene Behaviors.

2018-04-01

The aim of this article is to describe the associations of nurses' hand hygiene (HH) attitudes, subjective norms, and perceived behavioral control with observed and self-reported HH behavior. Hand hygiene is an essential strategy to prevent healthcare-associated infections. Despite tremendous efforts, nurses' HH adherence rates remain suboptimal. This quantitative descriptive study of ICU nurses in the southeastern United States was guided by the theory of planned behavior. The self-administered Patient Safety Opinion Survey and iScrub application, which facilitates observation, comprised the data set. Nurses' observed HH median was 55%; tendency to self-report was a much higher 90%. Subjective norm and perceived control scores were associated with observed and self-reported HH (P < .05) but not attitude scores or reports of intention. Nurses' subjective norm and perceived control are associated with observed and self-reported HH performance. Healthcare workers overestimate their HH performance. Findings suggest future research to explore manipulators of these variables to change nurses' HH behavior.

Student attendance is thought to be an important factor in the academic performance of medical students, in addition to having important regulatory, policy, and financial implications for medical educators. However, this relationship has not been well evaluated within clinical learning environments. To evaluate the relationship between student attendance and academic performance in a medical student obstetrics/gynecology clinical rotation. A prospective cohort study of student attendance at clinical and tutorial-based activities during a full academic year (September 2011 to June 2012) within a publicly funded university teaching hospital in Dublin, Ireland. Students were expected to attend 64 activities (26 clinical activities and 38 tutorial-based activities) but attendance was not mandatory. All 147 fourth-year medical students who completed an 8-week obstetrics/gynecology rotation were included. Student attendance at clinical and tutorial-based activities, recorded using a paper-based logbook. The overall examination score (out of a possible 200 points) was obtained using an 11-station objective structured clinical examination (40 points), an end-of-year written examination comprising 50 multiple-choice questions (40 points) and 6 short-answer questions (40 points), and an end-of-year long-case clinical/oral examination (80 points). Students were required to have an overall score of 100 points (50%) and a minimum of 40 points in the long-case clinical/oral examination (50%) to pass. The mean attendance rate was 89% (range, 39%-100% [SD, 11%], n = 57/64 activities). Male students (84% attendance, P = .001) and students who failed an end-of-year examination previously (84% attendance, P = .04) had significantly lower rates. There was a positive correlation between attendance and overall examination score (r = 0.59 [95% CI, 0.44-0.70]; P year examination, and the timing of the rotation during the academic year.

Hand washing is recognized as a crucial step in preventing foodborne disease transmission by mitigating crosscontamination among hands, surfaces, and foods. This research was undertaken to establish the importance of several keys factors (soap, soil, time, and drying method) in reducing microorganisms during hand washing. A nonpathogenic nalidixic acid-resistant Enterobacter aerogenes surrogate for Salmonella was used to assess the efficacy of using soap or no soap for 5 or 20 s on hands with or without ground beef debris and drying with paper towel or air. Each experiment consisted of 20 replicates, each from a different individual with ∼ 6 log CFU/ml E. aerogenes on their hands. A reduction of 1.0 ± 0.4 and 1.7 ± 0.8 log CFU of E. aerogenes was observed for a 5-s wash with no soap and a 20-s wash with soap, respectively. When there was no debris on the hands, there was no significant difference between washing with and without soap for 20 s (P > 0.05). Likewise, there was no significant difference in the reductions achieved when washing without soap, whether or not debris was on the hands (P > 0.05). A significantly greater reduction (P soap when there was ground beef debris on the hands. The greatest difference (1.1 log CFU greater average reduction) in effectiveness occurred when ground beef debris was on the hands and a 20-s wash with water was compared with a 20-s wash with soap. Significantly greater (P 4.0 log CFU per towel) when hands are highly contaminated. Our results support future quantitative microbial risk assessments needed to effectively manage risks of foodborne illness in which food workers' hands are a primary cause.

Hand cumulative trauma disorders in Nigerian custom tailors: the need for redesign of manual scissors.

Cutting scissors are important working tools for Nigerian custom tailors (CTs) but its usage apparently does not meet the ergonomics need of these artisans. A survey was carried out amongst CTs using questionnaires to obtain their background social-occupational demographics and observation methods to study their work performance, use of scissors and any cumulative trauma disorder (CTD) in their hands. Thicknesses of various fabrics were measured and comparison between Western world's custom tailoring job and the Nigerian type was done. The results showed some CTD risk factors with finger contusions on the 71 CTs evaluated. The right-hand contusions were traced to the constant usage of unpadded manual scissors with ungloved hands. Disparity between Western and Nigerian tailoring practice may account for the high occurrence of disorders in Nigerian CTs. Since hand dimensions are crucial in the design of hand tools, it is therefore concluded that hand anthropometry of Nigerian CTs and soft padding of manual scissors may mitigate CTD burdens on CTs' hands. Cumulative trauma disorders on the hands of low-income Nigerian CTs needed investigation. This was done via self-assessment and observational methods of the artisans’ work system. Frequent usage of unpadded manual scissors with un-gloved hands cause and exacerbate the problem. Hand anthropometry of users is crucial in scissors manufacturing.

Hand hygiene is the mainstay of nosocomial infection prevention. This study was a baseline survey to assess hand hygiene compliance of healthcare workers by direct observation in three major hospitals of Isfahan, Iran. The use of different hand hygiene products was also evaluated. In 3078 potential opportunities hand hygiene products were available on 2653 occasions (86.2%). Overall compliance was 6.4% (teaching hospital: 7.4%; public hospital: 6.2%; private hospital: 1.4%). Nurses (8.4%) had the highest rates of compliance. Poor hand hygiene compliance in Isfahan hospitals necessitates urgent interventions to improve both hospital infrastructure and staff knowledge. © 2013 The Healthcare Infection Society.

This study aims to develop a robotic hand as a substitute for a surgeon's hand in hand-assisted laparoscopic surgery (HALS). We determined the requirements for the proposed hand from a surgeon's motions in HALS. We identified four basic behaviors: "power grasp," "precision grasp," "open hand for exclusion," and "peace sign for extending peritoneum." The proposed hand had the minimum necessary DOFs for performing these behaviors, five fingers as in a human's hand, a palm that can be folded when a surgeon inserts the hand into the abdomen, and an arm for adjusting the hand's position. We evaluated the proposed hand based on a performance test and a physician's opinions, and we confirmed that it can grasp organs.

Nosocomial infections are considered a major risk factor in hospital wards, and hand hygiene is the first step in their control. An observational study was conducted in 2015 with 200 nurses working in intensive care units in teaching hospitals of Tabriz, Iran. Data were collected by using the Hand Hygiene Observation Tool questionnaire. The researchers monitored nurses' opportunities for hand hygiene during the 8-week period from February 3-April 4, 2015. A total of 1,067 opportunities occurred for hand hygiene before and after wearing gloves. The results show that hand hygiene compliance before wearing gloves is poor among nurses who work in intensive care units (14.8%). Therefore it is necessary to conduct effective interventions through continuing education programs to improve hand hygiene compliance.

Association between Breastfeeding Duration and Type of Birth Attendant

Directory of Open Access Journals (Sweden)

Jordyn T. Wallenborn

2018-01-01

Full Text Available Introduction. Healthcare providers play an integral role in breastfeeding education and subsequent practices; however, the education and support provided to patients may differ by type of provider. The current study aims to evaluate the association between type of birth attendant and breastfeeding duration. Methods. Data from the prospective longitudinal study, Infant Feeding Practices Survey II, was analyzed. Breastfeeding duration and exclusive breastfeeding duration were defined using the American Academy of Pediatrics’ national recommendations. Type of birth attendant was categorized into obstetricians, other physicians, and midwife or nurse midwife. If mothers received prenatal care from a different type of provider than the birth attendant, they were excluded from the analysis. Multinomial logistic regression was conducted to obtain crude and adjusted odds ratios and 95% confidence intervals. Results. Compared to mothers whose births were attended by an obstetrician, mothers with a family doctor or midwife were twice as likely to breastfeed at least six months. Similarly, mothers with a midwife birth attendant were three times as likely to exclusively breastfeed less than six months and six times more likely to exclusively breastfeed at least six months compared to those who had an obstetrician birth attendant. Conclusions. Findings from the current study highlight the importance of birth attendants in breastfeeding decisions. Interventions are needed to overcome barriers physicians encounter while providing breastfeeding support and education. However, this study is limited by several confounding factors that have not been controlled for as well as by the self-selection of the population.

The occupational health and safety of flight attendants.

Science.gov (United States)

Griffiths, Robin F; Powell, David M C

2012-05-01

In order to perform safety-critical roles in emergency situations, flight attendants should meet minimum health standards and not be impaired by factors such as fatigue. In addition, the unique occupational and environmental characteristics of flight attendant employment may have consequential occupational health and safety implications, including radiation exposure, cancer, mental ill-health, musculoskeletal injury, reproductive disorders, and symptoms from cabin air contamination. The respective roles of governments and employers in managing these are controversial. A structured literature review was undertaken to identify key themes for promoting a future agenda for flight attendant health and safety. Recommendations include breast cancer health promotion, implementation of Fatigue Risk Management Systems, standardization of data collection on radiation exposure and health outcomes, and more coordinated approaches to occupational health and safety risk management. Research is ongoing into cabin air contamination incidents, cancer, and fatigue as health and safety concerns. Concerns are raised that statutory medical certification for flight attendants will not benefit either flight safety or occupational health.

Hand hygiene is acknowledged as the single most important measure to prevent nosocomial infections in the healthcare setting. Similarly, in non-clinical settings, hand hygiene is recognised as a key element in helping prevent the spread of infectious diseases. The aim of this study was to evaluate the efficacy of three different disinfectant hand sanitizers in reducing the burden of bacterial hand contamination in 60 healthy volunteers in a community setting, both before and after education about the correct use of hand sanitizers. The study is the first to evaluate the efficacy and ease of use of different formulations of hand rubs used by the general population. The products tested were: Sterillium (perfumed, liquid), desderman pure gel (odorless, gel) and Lavit (perfumed, spray). Sterillium and desderman are EN1500 (hygienic hand rub) certified products (available in pharmacy) and Lavit is non EN1500 certified and available in supermarkets. The two EN1500 certified products were found to be significantly superior in terms of reducing bacterial load. desderman pure gel, Sterillium and Lavit reduced the bacterial count to 6.4%, 8.2% and 28.0% respectively. After education in the correct use of each hand rub, the bacterial load was reduced even further, demonstrating the value of education in improving hand hygiene. Information about the testers' perceptions of the three sanitizers, together with their expectations of a hand sanitizer was obtained through a questionnaire. Efficacy, followed by skin compatibility were found to be the two most important attributes of a hand disinfectant in our target group. PMID:25379773

Handwashing education and promotion are well established as effective strategies to reduce diarrhea and respiratory illness in countries around the world. However, access to reliable water supplies has been identified as an important barrier to regular handwashing in low-income countries. Alcohol-based hand sanitizer (ABHS) is an effective hand hygiene method that does not require water, but its use is not currently recommended when hands are visibly soiled. This study evaluated the efficacy of ABHS on volunteers' hands artificially contaminated with Escherichia coli in the presence of dirt (soil from Tanzania) and cooking oil. ABHS reduced levels of E. coli by a mean of 2.33 log colony forming units (CFU) per clean hand, 2.32 log CFU per dirt-covered hand, and 2.13 log CFU per oil-coated hand. No significant difference in efficacy was detected between hands that were clean versus dirty or oily. ABHS may be an appropriate hand hygiene method for hands that are moderately soiled, and an attractive option for field settings in which access to water and soap is limited.

Full Text Available Background. Embodied finger counting has been shown to have cross-cultural differences in previous studies (Lindemann, Alipour, & Fisher, 2011; Soto & Lalain, 2008. However, their results were contradictory in reference to Western populations with regard to the hand preferred: The first study showed that in Western countries — Europe and the United States — participants preferred to start with the left hand (whereas in the Middle East — Iran — they used the right hand; the second study showed that participants in France preferred the right hand. Objective. Our study aimed to observe these differences in two countries, Spain (Western Europe and Russia (Eastern Europe part, although taking into account the variety of cultural or ethnic groups who live there. Design. The observational/descriptive study, together with correlational analysis of the finger-counting pattern (from 1 to 10 used by children aged 10 to 12 who had not been taught to use their fingers for counting, considered factors of cultural origin and hand dominance. The possible effects of this action on cognition — in our case, math achievement — were considered also. Results and conclusion. The differences in the frequency of the finger-counting patterns might suggest cultural-individual differences in performance; however, the correlational analysis did not reveal that these differences were statistically significant, either for gender or for mark in math. However, hand dominance was a significant predictor of the preferred hand with which to start counting.

Rapid estimation of acute hand burns is important for communication, standardisation of assessment, rehabilitation and research. Use of an individual's own thumbprint area as a fraction of their total hand surface area was evaluated to assess potential utility in hand burn evaluation. Ten health professionals used an ink-covered dominant thumb pulp to cover the surfaces of their own non-dominant hand using the contralateral thumb. Thumbprints were assessed on the web spaces, sides of digits and dorsum and palm beyond the distal wrist crease. Hand surface area was estimated using the Banerjee and Sen method, and thumbprint ellipse area calculated to assess correlation. Mean estimated total hand surface area was 390.0cm 2 ±SD 51.5 (328.3-469.0), mean thumbprint ellipse area was 5.5cm 2 ±SD 1.3 (3.7-8.4), and mean estimated print number was 73.5±SD 11.0 (range 53.1-87.8, 95% CI 6.8). The mean observed number of thumbprints on one hand was 80.1±SD 5.9 (range 70.0-88.0, 95% CI 3.7), χ 2 =0.009. The combined mean of digital prints was 42, comprising a mean of two prints each on volar, dorsal, radial and ulnar digit surfaces, except volar middle and ring (3 prints each). Palmar prints were 15 (11-19), dorsal 15 (11-19), ulnar palm border 3, first web space 2, and second, third and fourth web spaces one each. Using the surface of the palm alone, excluding digits, as 0.5% of total body surface area, the area of one thumbprint was approximated as 1/30th of 1%. We have demonstrated how thumbprint area serves as a simple method for evaluating hand burn surface area. Copyright © 2018 Elsevier Ltd and ISBI. All rights reserved.

Several extensions of the Standard Model contain right-handed (sterile) neutrinos in the GeV-TeV mass range. Due to their mixing with the active neutrinos, they may give rise to novel effects in cosmology, neutrino physics, and collider searches. In addition, right-handed neutrinos can also appear as final states from dark matter annihilations, with important implications for dark matter indirect detection searches. In this paper, we use current data from the Fermi Large Area Telescope (6-year observation of dwarf spheroidal galaxies) and H.E.S.S. (10-year observation of the Galactic center) to constrain the annihilation of dark matter into right-handed neutrinos. We consider right-handed neutrino with masses between 10 GeV and 1 TeV, including both two-body and three-body decays, to derive bounds on the dark matter annihilation rate, ( σ v ), as a function of the dark matter mass. Our results show, in particular, that the thermal dark matter annihilation cross section, 3× 10{sup −26} cm{sup 3} s {sup −1} , into right-handed neutrinos is excluded for dark matter masses smaller than 200 GeV.

The rubber hand illusion is an experimental paradigm in which participants consider a fake hand to be part of their body. This paradigm has been used in many domains of psychology (i.e., research on pain, body ownership, agency) and is of clinical importance. The classic rubber hand paradigm nevertheless suffers from limitations, such as the absence of active motion or the reliance on approximate measurements, which makes strict experimental conditions difficult to obtain. Here, we report on the development of a novel technology-a robotic, user- and computer-controllable hand-that addresses many of the limitations associated with the classic rubber hand paradigm. Because participants can actively control the robotic hand, the device affords higher realism and authenticity. Our robotic hand has a comparatively low cost and opens up novel and innovative methods. In order to validate the robotic hand, we have carried out three experiments. The first two studies were based on previous research using the rubber hand, while the third was specific to the robotic hand. We measured both sense of agency and ownership. Overall, results show that participants experienced a "robotic hand illusion" in the baseline conditions. Furthermore, we also replicated previous results about agency and ownership.

The didactic conference is a common part of the resident education curriculum. Given the demands of clinical responsibilities and restrictions on duty hours, maximising education is a challenge faced by all residency programmes. To date, little research exists with respect to how the provision of complimentary food affects physician and resident conference attendance. The objective of this study was to determine whether complimentary food improves resident arrival times and attendance at educational conferences and, furthermore, to test whether this provision is a potentially cost-effective tool for improving education. A retrospective review of 36 resident educational Friday noon conferences, including 1043 resident arrivals, was performed. Data were analysed for total attendance, arrival times, number needed to eat (NNE) and the percentage of residents arriving on time, and compared between days on which food was and was not provided. Median attendance was 3.7% higher (p = 0.04) on days on which food was provided, at a cost of US$46 for each additional resident in attendance. Arrival times were also statistically significantly improved when food was provided, with a median improvement of 0.7 minutes (p = 0.02) and an 11.0% increase in on-time arrivals (p < 0.001). The NNE was 10.6. Complimentary food improves both attendance and arrival times by a small, but statistically significant, degree. The provision of complimentary food can be considered as an incentive for attendance and on-time arrival at didactic educational sessions, although more cost-effective modalities may exist. © 2016 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

Hand hygiene and aseptic techniques are essential preventives in combating hospital-acquired infections. However, implementation of these strategies in the operating room remains suboptimal. There is a paucity of intervention studies providing detailed information on effective methods for change. This study aimed to evaluate the process of implementing a theory-driven knowledge translation program for improved use of hand hygiene and aseptic techniques in the operating room. The study was set in an operating department of a university hospital. The intervention was underpinned by theories on organizational learning, culture and person centeredness. Qualitative process data were collected via participant observations and analyzed using a thematic approach. Doubts that hand-hygiene practices are effective in preventing hospital acquired infections, strong boundaries and distrust between professional groups and a lack of psychological safety were identified as barriers towards change. Facilitated interprofessional dialogue and learning in "safe spaces" worked as mechanisms for motivation and engagement. Allowing for the free expression of different opinions, doubts and viewing resistance as a natural part of any change was effective in engaging all professional categories in co-creation of clinical relevant solutions to improve hand hygiene. Enabling nurses and physicians to think and talk differently about hospital acquired infections and hand hygiene requires a shift from the concept of one-way directed compliance towards change and learning as the result of a participatory and meaning-making process. The present study is a part of the Safe Hands project, and is registered with ClinicalTrials.gov (ID: NCT02983136 ). Date of registration 2016/11/28, retrospectively registered.

Although variations in the standard prehensile pattern can be found in the literature, these alternative patterns have never been studied systematically. This was the goal of the current paper. Ten participants picked up objects with a pincer grip. Objects (3, 5, or 7cm in diameter) were placed at 30, 60, 90, or 120cm from the hands' starting location. Usually the hand was opened gradually to a maximum immediately followed by hand closing, called the standard hand opening pattern. In the alternative opening patterns the hand opening was bumpy, or the hand aperture stayed at a plateau before closing started. Two participants in particular delayed the start of grasping with respect to start of reaching, with the delay time increasing with object distance. For larger object distances and smaller object sizes, the bumpy and plateau hand opening patterns were used more often. We tentatively concluded that the alternative hand opening patterns extended the hand opening phase, to arrive at the appropriate hand aperture at the appropriate time to close the hand for grasping the object. Variations in hand opening patterns deserve attention because this might lead to new insights into the coordination of reaching and grasping. Copyright © 2011 Elsevier B.V. All rights reserved.

BACKGROUND: Anxiety disorders are one of the most psychiatric disorders in children and adolescents that can cause long life functional disability. The first line treatment for this disorder is cognitive behavioral therapy that has primary, secondary and tertiary preventive effect, but is expensive and long time. Today there is some effort to find short term, group, semi-attendance and low cost therapies. METHODS: Subjects were 42 girls (12- 17 y) with at least one anxiety disorder according to DSM-IV-TR with their parents who were divided into two groups randomly: group A which participated in 8 sessions and group B which participated in 4 sessions and the contents of sessions 3, 4, 6, and 7 were recorded on a CD for them. The tests used in this study were: SCARED, CATS, CAIS-C, CAIS-P, conducted before (T0), just after (T1) and three months after the treatment (T2). The collected data were analyzed by multivariate analysis of covariance test using SPSS software package, version 15.0. RESULTS: There was no significant difference between efficacy of semi-attendance group CBT and attendance group CBT in T0, T1 and T2 according to 4 tests (p = 0.311). The difference between the scores of these tests between T0 andT1 and T0 and T2 was significant in both groups (p < 0.001) but the difference between T1 and T2 was not significant. (p = 0.771). CONCLUSIONS: The efficacy of semi-attendance group CBT and attendance group CBT is similar and would sustain after 3 months. PMID:21526093

The term affordance defines a property of objects, which relates to the possible interactions that an agent can carry out on that object. In monkeys, canonical neurons encode both the visual and the motor properties of objects with high specificity. However, it is not clear if in humans exists a similarly fine-grained description of these visuomotor transformations. In particular, it has not yet been proven that the processing of visual features related to specific affordances induces both specific and early visuomotor transformations, given that complete specificity has been reported to emerge quite late (300-450ms). In this study, we applied an adaptation-stimulation paradigm to investigate early cortico-spinal facilitation and hand movements׳ synergies evoked by the observation of tools. We adapted, through passive observation of finger movements, neuronal populations coding either for precision or power grip actions. We then presented the picture of one tool affording one of the two grasps types and applied single-pulse Transcranial Magnetic Stimulation (TMS) to the hand primary motor cortex, 150ms after image onset. Cortico-spinal excitability of the Abductor Digiti Minimi and Abductor Pollicis Brevis showed a detailed pattern of modulations, matching tools׳ affordances. Similarly, TMS-induced hand movements showed a pattern of grip-specific whole hand synergies. These results offer a direct proof of the emergence of an early visuomotor transformation when tools are observed, that maintains the same amount of synergistic motor details as the actions we can perform on them.

Full Text Available Abstract Background Symptomatic osteoarthritis (OA affects approximately 10% of adults aged over 60 years. The foot joint complex is commonly affected by OA, yet there is relatively little research into OA of the foot, compared with other frequently affected sites such as the knee and hand. Existing epidemiological studies of foot OA have focussed predominantly on the first metatarsophalangeal joint at the expense of other joints. This three-year prospective population-based observational cohort study will describe the prevalence of symptomatic radiographic foot OA, relate its occurrence to symptoms, examination findings and life-style-factors, describe the natural history of foot OA, and examine how it presents to, and is diagnosed and managed in primary care. Methods All adults aged 50 years and over registered with four general practices in North Staffordshire, UK, will be invited to participate in a postal Health Survey questionnaire. Respondents to the questionnaire who indicate that they have experienced foot pain in the preceding twelve months will be invited to attend a research clinic for a detailed clinical assessment. This assessment will consist of: clinical interview; physical examination; digital photography of both feet and ankles; plain x-rays of both feet, ankles and hands; ultrasound examination of the plantar fascia; anthropometric measurement; and a further self-complete questionnaire. Follow-up will be undertaken in consenting participants by postal questionnaire at 18 months (clinic attenders only and three years (clinic attenders and survey participants, and also by review of medical records. Discussion This three-year prospective epidemiological study will combine survey data, comprehensive clinical, x-ray and ultrasound assessment, and review of primary care records to identify radiographic phenotypes of foot OA in a population of community-dwelling older adults, and describe their impact on symptoms, function and

Brain-imaging research has shown that a viewed acting hand is mapped to the observer's hand representation that corresponds with the identity of the hand. In contrast, behavioral research has suggested that rather than representing a seen hand in relation to one's own manual system, it is represented in relation to the midline of an imaginary…

Objectives To evaluate the impact of implementing a simple, user-friendly eLearning module on hand hygiene (HH) compliance and infection rates. Design Preintervention and postintervention observational study. Participants All neonates admitted to the neonatal intensive care unit (NICU) over the study period were eligible for participation and were included in the analyses. A total of 3422 patients were admitted over a 36-month span (July 2009 to June 2012). Interventions In the preintervention and postintervention periods (phases I and II), all healthcare providers were trained on HH practices using an eLearning module. The principles of the ‘4 moments of HH’ and definition of ‘baby space’ were incorporated using interactive tools. The intervention then extended into a long-term sustainability programme (phase III), including the requirement of an annual recertification of the module and introduction of posters and screensavers throughout the NICU. Primary and secondary outcome measures The primary outcome was HH compliance rates among healthcare providers in the three phases. The secondary outcome was healthcare-associated infection rates in the NICU. Results HH compliance rates declined initially in phase II then improved in phase III with the addition of a long-term sustainability programme (76%, 67% and 76% in phases I, II and III, respectively (pchallenging to implement and sustain with the need for ongoing reinforcement and education.

To explore the relationship between laterality recognition after stroke and impairments in attention, 3D object rotation and functional ability. Observational cross-sectional study. Acute care teaching hospital. Thirty-two acute and sub-acute people with stroke and 36 healthy, age-matched controls. Laterality recognition, attention and mental rotation of objects. Within the stroke group, the relationship between laterality recognition and functional ability, neglect, hemianopia and dyspraxia were further explored. People with stroke were significantly less accurate (69% vs 80%) and showed delayed reaction times (3.0 vs 1.9 seconds) when determining the laterality of a pictured hand. Deficits either in accuracy or reaction times were seen in 53% of people with stroke. The accuracy of laterality recognition was associated with reduced functional ability (R(2) = 0.21), less accurate mental rotation of objects (R(2) = 0.20) and dyspraxia (p = 0.03). Implicit motor imagery is affected in a significant number of patients after stroke with these deficits related to lesions to the motor networks as well as other deficits seen after stroke. This research provides new insights into how laterality recognition is related to a number of other deficits after stroke, including the mental rotation of 3D objects, attention and dyspraxia. Further research is required to determine if treatment programmes can improve deficits in laterality recognition and impact functional outcomes after stroke.

Full Text Available A 45-year-old man presented with painless subcutaneous masses bilaterally on his hands and loss of motion or contracture of the fingers. Initially, drug therapy to reduce the serum uric acid was administered and was expected to reduce the tophi. However, during observation at the clinic, spontaneous rupture of an extensor tendon occurred, and surgical repair of the tendon and resection of the masses were performed. Surgical exploration of the right hand showed hypertrophic white-colored crystal deposits that both surrounded and invaded the extensor digitorum communis of the index finger, which was ruptured. Histopathologic examination of the specimen demonstrated findings consistent with gouty tophi. Tophaceous gout can induce a rupture of tendons during clinical observation, and surgical resection of the tophi might be needed to prevent ruptures.

Full Text Available A structural representation of the hand embedding information about the identity and relative position of fingers is necessary to counting routines. It may also support associations between numbers and allocentric spatial codes that predictably interact with other known numerical spatial representations, such as the mental number line. In this study, 48 Western participants whose typical counting routine proceeded from thumb-to-little on both hands performed magnitude and parity binary judgments. Response keys were pressed either with the right index and middle fingers or with the left index and middle fingers in separate blocks. 24 participants responded with either hands in prone posture (i.e. palm down and 24 participants responded with either hands in supine (i.e. palm up posture. When hands were in prone posture, the counting direction of the left hand conflicted with the direction of the left-right mental number line, whereas the counting direction of the right hand was consistent with it. When hands were in supine posture, the opposite was true. If systematic associations existed between relative number magnitude and an allocentric spatial representation of the finger series within each hand, as predicted on the basis of counting habits, interactions would be expected between hand posture and a unimanual version of the Spatial-Numerical Association of Response Codes (SNARC effect. Data revealed that with hands in prone posture a unimanual SNARC effect was present for the right hand, and with hands in supine posture a unimanual SNARC effect was present for the left hand. We propose that a posture-invariant body structural representation of the finger series provides a relevant frame of reference, a within-hand directional vector, that is associated to simple number processing. Such frame of reference can significantly interact with stimulus-response correspondence effects that have been attributed to the mapping of numbers on a mental

This review is to explore the factors affecting the uptake of skilled birth attendants for delivery and the issues associated with women's role and choices of maternal health care service for delivery in Nepal. Literature was reviewed across the globe and discussed in a Nepalese context. Delivery by Skilled Birth Attendance serves as an indicator of progress towards reducing maternal mortality worldwide, the fifth Millennium Development Goal. Nepal has committed to reducing its maternal mortality by 75% by 2015 through ensuring accessibility to the availability and utilisation of skilled care at every birth. The literature suggests that several socio-economic, cultural and religious factors play a significant role in the use of Skilled Birth Attendance for delivery in Nepal. Availability of transportation and distance to the health facility; poor infrastructure and lack of services; availability and accessibility of the services; cost and convenience; staff shortages and attitudes; gender inequality; status of women in society; women's involvement in decision making; and women's autonomy and place of residence are significant contributing factors for uptake of Skilled Birth Attendance for delivery in Nepal. The review found more quantitative research studies exploring the determinants of utilisation of the maternal health services during pregnancy in Nepal than qualitative studies. Findings of quantitative research show that different social demographic, economic, socio-cultural and religious factors are responsible for the utilisation of maternal health services but very few studies discussed how and why these factors are responsible for utilisation of skilled birth attendants in pregnancy. It is suggested that there is need for more qualitative research to explore the women's role and choice regarding use of skilled birth attendants services and to find out how and why these factors are responsible for utilisation of skilled birth attendants for delivery

Background Oral and pharyngeal cancer is highly treatable if diagnosed early, yet late diagnosis is commonplace apparently because of delays in undergoing an oral cancer examination. Purpose We explored predictors of scheduling and attending an oral cancer examination among a sample of Black and White men who were at high risk for oral cancer because they smoked. Methods During an in-person interview, participants (N = 315) from rural Florida learned about oral and pharyngeal cancer, completed survey measures, and were offered a free examination in the next week. Later, participants received a follow-up phone call to explore why they did or did not attend their examination. Results Consistent with the notion that scheduling and attending an oral cancer exam represent distinct decisions, we found that the two outcomes had different predictors. Defensive avoidance and exam efficacy predicted scheduling an examination; exam efficacy and having coping resources, time, and transportation predicted attending the examination. Open-ended responses revealed that the dominant reasons participants offered for missing a scheduled examination was conflicting obligations, forgetting, and confusion or misunderstanding about the examination. Conclusions The results suggest interventions to increase scheduling and attending an oral cancer examination. PMID:26152644

Robotically enhanced rubber hand illusion.

The rubber hand illusion is a well-known multisensory illusion. In brief, watching a rubber hand being stroked by a paintbrush while one's own unseen hand is synchronously stroked causes the rubber hand to be attributed to one's own body and to "feel like it's my hand." The rubber hand illusion is thought to be triggered by the synchronized tactile stimulation of both the subject's hand and the fake hand. To extend the conventional rubber hand illusion, we introduce robotic technology in the form of a master-slave telemanipulator. The developed one degree-of-freedom master-slave system consists of an exoskeleton master equipped with an optical encoder that is worn on the subject's index finger and a motor-actuated index finger on the rubber hand, which allows the subject to perform unilateral telemanipulation. The moving rubber hand illusion has been studied by several researchers in the past with mechanically connected rigs between the subject's body and the fake limb. The robotic instruments let us investigate the moving rubber hand illusion with less constraints, thus behaving closer to the classic rubber hand illusion. In addition, the temporal delay between the body and the fake limb can be precisely manipulated. The experimental results revealed that the robotic instruments significantly enhance the rubber hand illusion. The time delay is significantly correlated with the effect of the multisensory illusion, and the effect significantly decreased at time delays over 100 ms. These findings can potentially contribute to the investigations of neural mechanisms in the field of neuroscience and of master-slave systems in the field of robotics.
