The aim was to evaluate if pain, disability, and work productivity are influenced by physical and psychosocial work exposures as well as by stress, up to 1 year after a randomized controlled trial treatment intervention, and to determine whether any such association differed between treatment and control groups. Ninety-seven working women suffering non-specific neck pain (n = 67 treatment group, n = 30 control group) were followed from end of treatment intervention and at 9- and 15-month follow-ups, respectively. Physical and psychosocial exposures, as well as perceived stress, were assessed after the treatment intervention. Pain, neck disability, and work productivity were assessed at baseline, after intervention 3 months later and at 9- and 15-month follow-ups. Longitudinal assessment was conducted using the exposure level at 3 months as predictor of pain, disability, and work productivity at 3, 9, and 15 months, respectively. Mixed models were used to estimate longitudinal associations, accounting for within-individual correlation of repeated outcome measures by incorporation of a random intercept. Age and duration of neck pain were adjusted for in all models. To evaluate group differences, interactions between exposures and treatment groups were estimated. High perceived stress was associated with more neck pain, more neck disability, and decreased work productivity in both cross-sectional and longitudinal analyses. High 'control of decision' was associated with less neck pain, less neck disability, and higher work productivity in cross-sectional analyses but only to less disability and higher productivity in longitudinal analyses. Shoulder/arm load was the only physical exposure variable that was significantly associated with work productivity in the univariate analyses. Only small differences were observed between treatment and control groups. High perceived stress and low 'control of decision' were associated with more neck pain, increased neck disability, and decreased work productivity. Treatment interventions for individuals with neck pain should take into account psychosocial workplace exposures and stress to improve intermediate and long-term results.

Working through a psychotherapy group's political cultures.

Macropolitical evolution, starting with authoritarian monarchism, has moved through anarchistic transitions either to the totalitarianism of fascism and communism or to liberal and social democracy. We posit analogous micropolitical development in process-oriented therapy groups: "dependence" and "counterdependence" corresponding to monarchism and anarchism; and "independence" and "interdependence" to liberal and social democracy, respectively. Transition from counterdependence to independence and interdependence may be: (1) facilitated through group members' cooperative experience of rebellion, or (2) blocked by collective identification, the internalization of dystopian or utopian fantasies that coalesce as "group-self" perceptions. We explore how group therapists work clinically with and through these several "political cultures" in the service of group and self transformation.

This study presents an empirical investigation of the ethical reasoning and ethical issues at stake in the daily work of physicians and molecular biologists in Denmark. The aim of this study was to test empirically whether there is a difference in ethical considerations and principles between Danish physicians and Danish molecular biologists, and whether the bioethical principles of the American bioethicists Tom L. Beauchamp and James F. Childress are applicable to these groups. This study is based on 12 semi-structured interviews with three groups of respondents: a group of oncology physicians working in a clinic at a public hospital and two groups of molecular biologists conducting basic research, one group employed at a public university and the other in a private biopharmaceutical company. In this sample, the authors found that oncology physicians and molecular biologists employed in a private biopharmaceutical company have the specific principle of beneficence in mind in their daily work. Both groups are motivated to help sick patients. According to the study, molecular biologists explicitly consider nonmaleficence in relation to the environment, the researchers' own health, and animal models; and only implicitly in relation to patients or human subjects. In contrast, considerations of nonmaleficence by oncology physicians relate to patients or human subjects. Physicians and molecular biologists both consider the principle of respect for autonomy as a negative obligation in the sense that informed consent of patients should be respected. However, in contrast to molecular biologists, physicians experience the principle of respect for autonomy as a positive obligation as the physician, in dialogue with the patient, offers a medical prognosis based upon the patients wishes and ideas, mutual understanding, and respect. Finally, this study discloses utilitarian characteristics in the overall conception of justice as conceived by oncology physicians and molecular biologists from the private biopharmaceutical company. Molecular biologists employed at a public university are, in this study, concerned with allocation, however, they do not propose a specific theory of justice. This study demonstrates that each of the four bioethical principles of the American bioethicists Tom L. Beauchamp & James F. Childress - respect for autonomy, beneficence, nonmaleficence and justice - are reflected in the daily work of physicians and molecular biologists in Denmark. Consequently, these principles are applicable in the Danish biomedical setting.

The purpose of the study was to investigate the relationship between different exercise modes and visuospatial working memory in healthy older adults. A cross-sectional design was adopted. A total of 111 healthy older adults were enrolled in the study. They were classified by the exercise-related questionnaire to be in an open-skill group, closed-skill group or sedentary group. In experiment 1, the participants performed a visuospatial working memory task. The results indicated that both closed-skill (p < 0.05) and open-skill (p < 0.01) groups reached a higher accuracy than the sedentary group. Experiment 2 examined whether the exercise-induced benefit of working memory was manifested in passive maintenance or active manipulation of working memory which was assessed by visuospatial short-term memory task and visuospatial mental rotation task, respectively. The results showed that the open-skill (p < 0.01) group was more accurate than the sedentary group in the visuospatial short-term memory task, whereas the group difference in the visuospatial mental rotation task was not significant. These findings combined to suggest that physical exercise was associated with better visuospatial working memory in older adults. Furthermore, open-skill exercises that demand higher cognitive processing showed selective benefit for passive maintenance of working memory.

Purpose The aim of this study was to evaluate the effect of a multidisciplinary intervention (MDI) compared to a brief intervention (BI) with respect to return to work (RTW), pain and disability in workers on sick leave because of neck or shoulder pain. Methods 168 study participants with sickness absence for 4-16 weeks due to neck or shoulder pain were enrolled in a hospital-based clinical study and randomized to either MDI or BI. The primary outcome was RTW obtained by a national registry on public transfer payments. Secondary outcomes were self-reported pain and disability levels. One-year follow-up RTW rates were estimated by Cox proportional hazard regression adjusted for gender, age, sick leave prior to inclusion, part-time sick leave and clinical diagnosis. Secondary outcomes were analysed using logistic and linear regression analysis for pain and disability, respectively. Results In the MDI group, 50 participants (59%) experienced four or more continuous weeks of RTW while 48 (58%) returned to work in the BI group during the 1 year of follow-up. Results showed a statistically non significant tendency towards a lower rate of RTW in the MDI group than in the BI group (adjusted HR = 0.84, 95% CI 0.54, 1.31). There were no statistically significant differences in secondary outcomes between the MDI and BI groups. Conclusion The brief and the multidisciplinary interventions performed equally with respect to both primary and secondary outcomes. The added focus on RTW in the multidisciplinary group did not improve RTW rates in this group.

It is possible that people with psychiatric disabilities who visit day centres have previous work experiences that may be seen as resources for their current engagement in day centre activities. Research in this respect seems to lack, however. To investigate work experiences among attendees at day centres for people with psychiatric disabilities and relationships with current type of day centre (work-oriented, meeting place-oriented or mixed), engagement in day centre activities, motivation and socio-demographic and health-related factors. Seventy-seven attendees responded to questionnaires. Global Assessment of Functioning, GAF, was also used. Work was categorised into Group I (professionals, semi-professionals), Group II (clerical support, services workers) and Group III (e.g. craft workers, elementary occupations). Almost everyone had previously had open-market employment; more than half for ≥ 10 years. Group I was more common in mixed centres, Group II in meeting place-oriented ones and Group III in work-oriented ones. Group I more frequently had college degree and was rated high on GAF functioning. Women were over-represented in Group II, and men in Group III and in meeting place-oriented centres. Attending mixed centres was more likely when having a college degree, scoring high on GAF functioning and being highly engaged in activities. Attendees at work-oriented day centres were characterised by being motivated for spending time alone and reporting a diagnosis of psychosis. The participants had unused working capacity. No clear-cut relationships were found between work experiences and the investigated correlates.

Dieterich, S; Perks, J; Fragoso, R

Purpose: Medical Physicists and Radiation Oncologists are two professions who should be working as a team for optimal patient care, yet lack of mutual understanding about each others respective role and work environment creates barriers To improve collaboration and learning, we designed a shared didactic and work space for physics and radiation oncology residents to maximize interaction throughout their professional training. Methods: Physician and Physics residents are required to take the same didactic classes, including journal clubs and respective seminars. The residents also share an office environment among the seven physician and two physic residents. Results: By maximizing didactic overlapmore » and sharing office space, the two resident groups have developed a close professional relationship and supportive work environment. Several joint research projects have been initiated by the residents. Awareness of physics tasks in the clinic has led to a request by the physician residents to change physics didactics, converting the physics short course into a lab-oriented course for the medical residents which is in part taught by the physics residents. The physics seminar is given by both residency groups; increased motivation and interest in learning about physics has led to several medical resident-initiated topic selections which generated lively discussion. The physics long course has changed toward including more discussion among residents to delve deeper into topics and study beyond what passing the boards would require. A supportive work environment has developed, embedding the two physics residents into a larger residents group, allowing them to find mentor and peers more easily. Conclusion: By creating a shared work and didactic environment, physician and physics residents have improved their understanding of respective professional practice. Resident-initiated changes in didactic practice have led to improved learning and joint research. A strong social support system has developed, embedding physics residents into a larger peer group.« less

To assess the impact of work-related musculoskeletal disorders (WRMDs) on work ability among workers. A total of 1686 workers in various occupations, such as administration and education, were enrolled as subjects using the random cluster sampling method. The WRMDs and work ability of all subjects were evaluated using standardized Nordic questionnaires for the analysis of musculoskeletal symptoms and the Work Ability Index (WAI) scale, respectively. Comparison of work ability and its classification between the disease group and the non-disease group was performed by paired t test, RxC table χ2 test, and the Wilcoxon rank-sum test. The relationship between work duration and work ability was analyzed by the Spearman correlation test and a multi-level model. (1). The work ability of workers in the disease group was significantly lower than that in the non-disease group (P<0.0 1). (2) There were significant differences in work ability between workers with different work durations (<10 years, 10-20 years, and ≥20 years) (F=22.124, P< 0.01). With the increase in work duration, the work ability of workers declined in both groups, and the work ability of workers in the disease group (Spearman coefficient rs=-0. 172, P<0.01) had a more significant decline than that in the non-disease group (Spearman coefficient rs=-0.104, P<0.01). WRMDs were important risk factors for the decrease in work ability among workers. (3) There were significant differences in constituent ratios and levels of work ability classification between the disease group and the non-disease group (χ2=121.097, P<0.01; Z=-10.699, P<0.01). The proportions of workers with poor and medium work ability in the disease group were significantly higher than those in the non-disease group, while the proportion of works with excellent work ability in the disease group was significantly lower than that in the non-disease group. The similar characteristics in constituent ratios and levels of work ability classification could be found between the disease group and the non- disease group in various occupations (P<0.01). WRMDs have a harmful effect on the work ability of workers, and the work ability of workers substantially declines with the increase in exposure time (work duration).

Shift work is closely related with workers' health. In particular, sleep is thought to be affected by shift work. In addition, shift work has been reported to be associated with the type or direction of shift rotation, number of consecutive night shifts, and number of off-duty days. We aimed to analyze the association between the night shift rotation interval and the quality of sleep reported by Korean female shift workers. In total, 2,818 female shift workers from the manufacturing industry who received an employee physical examination at a single university hospital from January to August in 2014 were included. Subjects were classified into three groups (A, B, and C) by their night shift rotation interval. The quality of sleep was measured using the Korean version of the Pittsburgh Sleep Quality Index (PSQI). Descriptive analysis, univariate logistic regression, and multivariate logistic regression were performed. With group A as the reference, the odds ratio (OR) for having a seriously low quality of sleep was 1.456 (95% CI 1.171-1.811) and 2.348 (95% CI 1.852-2.977) for groups B and C, respectively. Thus, group C with the shortest night shift rotation interval was most likely to have a low quality of sleep. After adjustment for age, obesity, smoking status, alcohol consumption, exercise, being allowed to sleep during night shifts, work experience, and shift work experience, groups B and C had ORs of 1.419 (95% CI 1.134-1.777) and 2.238 (95% CI 1.737-2.882), respectively, compared to group A. Our data suggest that a shorter night shift rotation interval does not provide enough recovery time to adjust the circadian rhythm, resulting in a low quality of sleep. Because shift work is influenced by many different factors, future studies should aim to determine the most optimal shift work model and collect accurate, prospective data.

Mukhopadhyay, S

1989-01-01

In India an increase in female employment outside the home has occurred during the last few decades, especially in urban areas. A working woman may face difficulties in attempting to fulfil the demands of both worlds, at home and outside, while a housewife may feel tired and irritated with her household chores and financial dependence. All these may cause stress for these groups of women. The present study compares a group of working mothers with their non-working counterparts with respect to: (a) stress level, measured in terms of their anxiety score; and (b) certain general indicators of health including a broad measure of stress. The results show that anxiety and health scores of the two groups of women are similar. Further, the health score and anxiety score seem to be correlated, more clearly among the working mothers.

Working environment conditions in rural areas according to psychosocial indices.

The aim of this work was to study psychosocial working environment factors among farmers and other people living in rural areas. The study was carried out as a cross-section investigation. All persons visiting local occupational health service centres for a health check up have been asked to answer an inquiry which was based on the Karasek-Theorell questionnaire on job strain. Five extra items on worry about the future were added. The questionnaire was completed by over 3,800 persons. Three of four indices showed significant difference with respect to sex. Women experienced less stimulance at work, authority over work and had a greater fear of the future. Farmers had a significantly higher index for psychological demands, stimulance at work as well as authority over work than other occupational groups. The index for authority over work was very high in comparison with presented results for different occupations in other studies. With respect to worry about the future, the farmers had a significantly higher index than nearly all the other occupational groups. The low risk of coronary heart disease (CHD) among farmers reported in other studies can probably be related to good psychosocial working environment as measured by the indices in this study as well as other known life style factors.

CNAs Making Meaning of Direct Care

Using qualitative data from 87 focus groups with CNAs in 16 nursing homes in Massachusetts, this study explores ways CNAs make meaning of their work despite devaluations such as lack of respect from management and residents, and the physical and emotional demands of such low status work. CNAs' meaning-making represents an effort to assert a positive identity rather than accept the stigmatization associated with their work. Assertions of the value help CNAs reconstitute their identities. Assertions of meaning, which depend upon providing good care to residents regardless of financial reward or management respect and support, make CNAs vulnerable to exploitation. PMID:18552321

We have evaluated the consequences of work organization on musculoskeletal health. Using a postal questionnaire, answered by 1600 female grocery store workers, their main work tasks were identified and four work groups were defined (cashier, picking, and delicatessen work, and a mixed group, who performed a mix of these tasks). The crude odds ratios (ORs) for neck/shoulder complaints were 1.5 (95% CI 1.0-2.2), 1.1 (0.7-1.5) and 1.6 (1.1-2.3), respectively, compared to mixed work. Adjusting for individual and psychosocial factors had no effect on these ORs. For elbows/hands, no significant differences were found. Technical measurements of the workload showed large differences between the work groups. Picking work was the most strenuous, while cashier work showed low loads. Quantitative measures of variation revealed for mixed work high between minutes variation and the highest between/within minutes variation. Combining work tasks with different physical exposure levels increases the variation and may reduce the risk of musculoskeletal complaints. Copyright © 2015 Elsevier Ltd and The Ergonomics Society.

1999-04-01

The pathogenic mechanism of grain dust (GD)-induced occupational asthma (OA) remains unclear. To understand further the mechanism of GD-induced OA. Fifteen employees working in a same GD industry, complaining of work-related respiratory symptoms, were enrolled and were divided into two groups according to the GD-bronchoprovocation test (BPT) result: six positive responders were grouped as group III, nine negative responders as group II and five healthy controls as group I. Serum GD-specific immunoglobulin (Ig)E (sIgE), specific IgG (sIgG) and specific IgG4 (sIgG4) antibodies were detected by enzyme-linked immunosorbent assay. Basophil histamine release was measured by the autofluorometric method, and changes of serum neutrophil chemotactic activity were observed by the Boyden chamber method. For clinical parameters such as degree of airway hyperresponsiveness to methacholine, duration of respiratory symptoms, exposure duration, and prevalences of serum sIgE, sIgG and sIgG4 antibodies, there were no significant differences between group II and III (P > 0.05, respectively). Serum neutrophil chemotactic activity increased significantly at 30 min and decreased at 240 min after the GD-BPT in group III subjects (P < 0.05, respectively), while no significant changes were noted in group II subjects (P > 0.05). Basophil histamine release induced by GD was significantly higher in group III than those of group I or group II (P < 0.05, respectively), while minimal release of anti-IgG4 antibodies was noted in all three groups. These results suggest that enhanced basophil histamine release and serum neutrophil chemotactic activity might contribute to the development of GD-induced occupational asthma.

2013-04-29

In an earlier published telephone interview study (n > 1,000) we have shown that retired shift workers subjectively report worse sleep than retired day workers. This laboratory study sought to determine whether these findings held up when objective polysomnograhic (PSG) measures of sleep were taken and whether retirees' circadian temperature rhythms differed as a function of shift work exposure. All completers of the telephone interview were invited to attend a 36-hour laboratory study for which participants were paid. This involved continuous core body temperature measurement (using an ingestible pill-based system) and 2 nights of PSG. Shift work exposure (plus other measures) was collected by taking a detailed work history. The second laboratory night was scored into sleep stages. Post hoc, we divided participants into 4 shift work exposure groups: 0 years (ie, no exposure to shift work), 1 to 7 years, 7 to 20 years, and >20 years. Sample sizes were 11, 16, 15, and 15, respectively, with approximate equality in mean age (71.7 years of age, 69.1 years of age, 70.0 years of age, and 70.4 years of age, respectively) and percent male (63%, 50%, 67%, and 73%, respectively). Shift work exposure was associated with worse PSG sleep in a dose-related fashion. The percentages of participants with sleep efficiency, 80% for the 0 years, 1 to 7 years, 7 to 20 years, and >20 years groups were 36%, 63%, 67%, and 73%, respectively ( P < 0.01), and the percentages with total sleep time (TST), 6 hours were 36%, 56%, 53%, and 73%, respectively ( P < 0.01). From the circadian rhythm record, shift work exposure appeared to result ( P = 0.06) in an increased spread of phase angles (difference between habitual bedtime and time of temperature trough). In conclusion, it appears likely that shift work may be related to a scarring of sleep and circadian rhythms. This may be associated with a change in the relationship between habitual sleep timing and the phase of the circadian pacemaker.

PubMed Central

Assadi, Seyedeh Negar

2015-01-01

Background: Disorders of renal system can cause renal failure; therefore screening is necessary especially in workers who are exposed to harmful materials. Hypertension, diabetes mellitus, and hazardous exposures are non-occupational and occupational risk factors for renal diseases. Aim: The objective of this study was to determine the effects of working in automotive industry on renal function in Iran. Subjects and Methods: In a historical cohort study, workers of automotive industry who worked in production and had low exposure to metal fumes were selected and divided to three groups with 5–10, 11–20, and 21–30 years work duration. risk factors for renal diseases were collected and analyzed with SPSS using one-way ANOVA, correlation coefficient and with P < 0.05 and relative risk with a confidence interval (CI). Results: The means of work duration in Groups (A), (B) and (C) were 9.8 (0.6), 13.8 (2.0), 22.3 (1.6) years respectively with ANOVA (F) =187.864 and P < 0.01. Glomerular filtration rate (GFR) was 59.75 (0.70), 59.16 (1.52) and 59.10 (2.23) in Groups (A), (B), and (C) respectfully The relative risk of creatinine clearance, uric acid and mean blood pressure were the highest in Group (B); 1.970 - CI, 0.541–7.169, 1.571 95% CI: 0.198–12.470, and 1.519 95% CI: 0.425–5.426, but the differences were not significant. Conclusion: GFRs were decreased with work duration, but the differences were not significant. Working in automotive Industry with low exposure to toxic metals and solvents has no significant effect on GFR, creatinine clearance, uric acid, and mean blood pressure. PMID:25861528

The aim of this study was to investigate whether stratifying patients according to the time period from admission to the start of regular working hours would help detect a weekend effect in acute stroke patients. Ischemic stroke patients admitted between October 2002 and March 2012 were analyzed. Working hours were defined as 9:00-17:00 on weekdays. Patients were divided into those admitted during working hours (no-wait group) and three other groups according to the time from admission to working hours: ≤24 h (short-wait group), 24-48 h (medium-wait group), and >48 h (long-wait group). The modified Rankin Scale score and mortality at three-months were compared among the groups. Of 5625 patients, 3323 (59%) were admitted outside working hours. The proportion of patients with an mRS score 0-1 at three-months showed a decreasing trend with the time period before working hours: 47% (no-wait group), 42% (short-wait group), 42% (medium-wait group), and 38% (long-wait group), respectively (P < 0·001). When the no-wait group was used as a reference, the odds ratio for modified Rankin Scale score 0-1 was 0·88 (95% confidence interval, 0·75-1·04) in the short-wait group, 0·86 (0·69-1·07) in the medium-wait group, and 0·67 (0·53-0·85) in the long-wait group after adjusting for sex, age, premorbid mRS score, previous morbidity, stroke severity, and vascular risk factors. Mortality at three-months was not different between the no-wait group and the other groups. A weekend effect might be evident if patients were stratified according to the time period from admission until working hours. © 2014 World Stroke Organization.

Effective interventions to prevent work stress and to improve health, well-being, and performance of employees are of the utmost importance. This quasi-experimental intervention study presents a specific method for diagnosis of psychosocial risk factors at work and subsequent development and implementation of tailored work stress interventions, the so-called DISCovery method. This method aims at improving employee health, well-being, and performance by optimizing the balance between job demands, job resources, and recovery from work. The aim of the study is to quantitatively assess the effectiveness of the DISCovery method in hospital care. Specifically, we used a three-wave longitudinal, quasi-experimental multiple-case study approach with intervention and comparison groups in health care work. Positive changes were found for members of the intervention groups, relative to members of the corresponding comparison groups, with respect to targeted work-related characteristics and targeted health, well-being, and performance outcomes. Overall, results lend support for the effectiveness of the DISCovery method in hospital care. PMID:29438350

Recipient-related factors, such as education level and type of health insurance, are known to affect heart transplantation outcomes. Pre-operative employment status has shown an association with survival in abdominal organ transplant patients. We sought to evaluate the effect of work status of heart transplant (HTx) recipients at the time of listing and at the time of transplantation on short- and long-term survival. We evaluated the United Network for Organ Sharing (UNOS) registry for all adult HTx recipients from 2001 to 2014. Recipients were grouped based on their work status at listing and at heart transplantation. Kaplan-Meier estimates illustrated 30-day, 1-year, 5-year, and 10-year survival comparing working with non-working groups. The Cox proportional hazards regression model was applied to adjust for covariates that could potentially confound the post-transplantation survival analysis. Working at listing for HTx was not significantly associated with 30-day and 1-year survival. However, 5- and 10-year mortality were 14.5% working vs 19.8% not working (p < 0.0001) and 16% working vs 26% not working (p < 0.0001), respectively. Working at HTx appeared to be associated with a survival benefit at every time interval, with a trend toward improved survival at 30 days and 1 year and a significant association at 5 and 10 years. Kaplan-Meier analysis demonstrated a 5% and 10% decrease in 5- and 10-year mortality, respectively, for the working group compared with the group not working at transplantation. The Cox proportional hazards regression model showed that working at listing and working at transplantation were each associated with decreased mortality (hazard ratio [HR] = 0.8, 95% confidence interval [CI] 0.71 to 0.91; and HR = 0.76, 95% CI 0.65 to 0.89, respectively). This study is the first analysis of UNOS STAR data on recipient work status pre-HTx demonstrating: (1) an improvement in post-transplant survival for working HTx candidates; and (2) an association between working pre-HTx and longer post-HTx survival. Given that work status before HTx may be a modifiable risk factor for better outcomes after HTx, we strongly recommend that UNOS consider these important findings for moving forward this patient-centered research on work status. Working at listing and working at HTx are associated with long-term survival benefits. The association may be reciprocal, where working identifies less ill patients and also improves well-being. Consideration should be given to giving additional weight to work status during organ allocation. Work status may also be a modifiable factor associated with better post-HTx outcomes.

Background: Potential health effects of the indoor environment in office buildings and aircraft have generated considerable concern in recent years. Aims: To analyse the prevalence of self reported respiratory symptoms and illnesses in flight attendants (FAs) and schoolteachers. Methods: Data were collected as part of a study of reproductive health among female FAs. The prevalences of work related eye, nose, and throat symptoms, wheezing, physician diagnosed asthma, chest illness, and cold or flu were calculated and stratified by smoking status in 1824 FAs and 331 schoolteachers. Results: FAs and teachers were significantly more likely to report work related eye (12.4% and 7.4 %, respectively), nose (15.7% and 8.1%), and throat symptoms (7.5% and 5.7%) than were other working women (2.9% eye, 2.7% nose, and 1.3% throat symptoms). FAs were significantly more likely than teachers and referent working women to report chest illness during the prior three years (32.9%, 19.3%, 7.2%, respectively). Both study groups were more likely to report five or more episodes of cold or flu in the past year than were other working women (10.2% of FAs, 8.2% of teachers, 2.3% of referents), and both groups were more likely to report wheezing than other working women (22.8% of FAs, 28.4% of teachers, 16.4% of referents). FAs were significantly less likely than teachers and other working women to report ever having been diagnosed with asthma (8.2%, 13.3%, 11.8%, respectively). Conclusions: Overall, FAs and schoolteachers report a higher prevalence of work related upper respiratory symptoms, chest illness, and cold or flu than the general working population. PMID:14634183

The study compares the work habits of two student groups in an introductory physics course, one in traditional and one in online sections. Both groups shared the same online materials and online homework, as well as the same discussion boards and examinations, but one group in addition had traditional lectures. The groups were compared with respect to amount and frequency of access to different online course resources. It was found that with few exceptions, both groups exhibited very similar work habits. Students in the online sections more frequently accessed content pages and more frequently contributed to course discussions. It was also found that regular access of the materials throughout the week, rather than only on homework deadline nights, is a predictor of success on examinations, and that this indicator is more reliable for students in the online sections. Overall, though, the effect of traditional lectures is minimal.

A prospective randomised trial to study the efficacy and safety of hydrocele sclerotherapy with phenol and polidocanol. Eighty-six patients with unilateral primary vaginal hydroceles were randomised into three groups: group 1 (phenol sclerotherapy) - 29 patients, group 2 (polidocanol sclerotherapy) - 29 patients and group 3 (operative treatment) - 28 patients. Sclerotherapy was performed on outpatient basis using either 5-10 ml of 5% phenol or 2-4 ml of 1% polidocanol, while patients in group 3 underwent surgical repair of hydrocele (Jaboulay's procedure). Statistical analysis was performed using ANOVA. The cure rates in group 1, 2 and 3 were 96.5%, 51.7% and 100%, respectively. The pain scores (visual analogue scale) in group 1, 2 and 3 at 1 week and 1 month were 14.5 and 1.8; 10.1 and 1.3; 64.0 and 10.6, respectively. There was significant difference among the three groups in mean hospital stay (1.8, 1.5 and 9.7 hours, respectively) and time to work resumption (1.3, 1.1 and 12.7 days, respectively). Statistically significant differences in pain scores and complications were observed between sclerotherapy and operative groups. Five percent phenol is a better sclerosant than 1% polidocanol and is as efficacious as operative treatment, with lesser morbidity and similar safety profile.

Active learning in college classes and participation in the workforce frequently hinge on small group work. However, group dynamics vary, ranging from equitable collaboration to dysfunctional groups dominated by one individual. To explore how group dynamics impact student learning, we asked students in a large-enrollment university biology class to self-report their experience during in-class group work. Specifically, we asked students whether there was a friend in their group, whether they were comfortable in their group, and whether someone dominated their group. Surveys were administered after students participated in two different types of intentionally constructed group activities: 1) a loosely-structured activity wherein students worked together for an entire class period (termed the ‘single-group’ activity), or 2) a highly-structured ‘jigsaw’ activity wherein students first independently mastered different subtopics, then formed new groups to peer-teach their respective subtopics. We measured content mastery by the change in score on identical pre-/post-tests. We then investigated whether activity type or student demographics predicted the likelihood of reporting working with a dominator, being comfortable in their group, or working with a friend. We found that students who more strongly agreed that they worked with a dominator were 17.8% less likely to answer an additional question correct on the 8-question post-test. Similarly, when students were comfortable in their group, content mastery increased by 27.5%. Working with a friend was the single biggest predictor of student comfort, although working with a friend did not impact performance. Finally, we found that students were 67% less likely to agree that someone dominated their group during the jigsaw activities than during the single group activities. We conclude that group activities that rely on positive interdependence, and include turn-taking and have explicit prompts for students to explain their reasoning, such as our jigsaw, can help reduce the negative impact of inequitable groups.

We measured the muscle buffer capacity (betam) and repeated-sprint ability (RSA) of young females, who were either team-sport athletes (n = 7), endurance trained (n = 6) or untrained but physically active (n = 8). All subjects performed a graded exercise test to determine VO(2peak) followed 2 days later by a cycle test of RSA (5 x 6 s, every 30 s). Resting muscle samples (Vastus lateralis) were taken to determine betam. The team-sport group had a significantly higher betam than either the endurance-trained or the untrained groups (181+/- 27 vs. 148 +/- 11 vs. 122 +/- 32 micromol H(+) g dm(-1) pH(-1) respectively; P < 0.05). The team-sport group also completed significantly more relative total work (299 +/- 27 vs. 263 +/- 31 vs. 223 +/- 21 J kg(-1), respectively; P < 0.05) and absolute total work (18.2 +/- 1.6 vs. 14.6 +/- 2.4 vs. 13.0 +/- 1.9 kJ, respectively; P < 0.05) than the endurance-trained or untrained groups during the RSA test. The team-sport group also had a greater post-exercise blood lactate concentration, but not blood pH. There was a significant correlation between betam and RSA (r = 0.67; P < 0.05). Our findings show that young females competing in team sports have a larger betam than either endurance-trained or untrained females. This may be the result of the intermittent, high-intensity activity during training and the match play of team-sport athletes. The team-sport athletes also had a greater RSA than either the endurance-trained or untrained subjects. The greater total work by team-sport athletes was predominantly due to a better performance during the early sprints of the repeated-sprint bout.

To evaluate the work life and job satisfaction of pediatric generalists and subspecialists in comparison to each other and to a group of general internists and internal medicine subspecialists. Data were collected by survey of a national sample of 5704 general pediatricians, subspecialty pediatricians, general internists, internal medicine subspecialists, and family physicians who were selected randomly from the American Medical Association Masterfile using stratified sampling with disproportionate weighting to ensure ethnic diversity and representation of high managed care areas. Surveys were mailed up to 4 times and contained 150 items that reflected 10 facets of physician job satisfaction as well as an assessment of individual and practice demographic information. This study reports data from all groups except for family medicine. The adjusted response rate was 58% for general pediatricians (n = 590), 67% for specialty pediatricians (n = 345), and 52% (n = 1823) for the entire pool. In comparison with general internists, general pediatricians were more likely to be female (44% vs 24%); to work part time (20% vs 12%); to have lower annual income ($125 679 vs $143 875); and to report significantly higher levels of job, career, and specialty satisfaction on a 5-point scale (3.81 vs 3.52, 3.80 vs 3.55, and 3.76 vs 3.17 respectively). In comparison with internal medicine subspecialists, pediatric subspecialists were more likely to be female (42% vs 22%); to work in academically affiliated settings (35% vs 17%); to have lower incomes ($156 284 vs $192 006); to receive significantly less time for a complete history and physical examination (39 minutes vs 51 minutes); and to report similar levels of job, career, and specialty satisfaction (3.69 vs 3.71, 3.74 vs 3.78, and 3.60 vs 3.47 respectively). Of all 4 physician groups, general pediatricians worked the fewest hours (50/week), spent the greatest percentage of time in the office and the lowest percentage in the hospital (58% and 16%, respectively), saw the lowest percentage of patients with complex medical and complex psychosocial problems (15% and 17%, respectively), and were the least likely to endorse symptoms of burnout or job stress (13% and 18%, respectively). In comparison, pediatric subspecialists worked longer hours (59/week), spent the lowest percentage of time in the office and the greatest percentage of time in the hospital (22% and 44%, respectively), saw a much higher percentage of patients with complex medical and complex psychosocial problems (46% and 25%, respectively), and reported significantly higher levels of burnout and job stress (23% and 26%, respectively). Despite lower incomes, general pediatricians reported the highest levels of satisfaction and the least job stress of all 4 physician groups, whereas pediatric subspecialists reported levels of stress and burnout that raise significant concerns for the workforce of pediatric subspecialists of the future. Initiatives that improve clinical workload, balance inpatient and outpatient hours, and increase personal time of pediatric subspecialists should be considered.

Is the working capacity of Liberian industrial workers increased by regular malaria prophylaxis?

1984-10-01

In a study of the impact of malaria prophylaxis upon the physical working capacity of Liberian industrial workers, two groups of men, one with and the other without malaria prophylaxis, were compared over a period of one year. At the beginning and at the end of the study, the haemoglobin concentration, haematocrit, blood volume and physical performance--measured by bicycle ergometry and expressed as work load at heart rate 170--were compared. No significant differences were found, either within or between the two groups. Routinely distributed malaria prophylaxis thus seems to be of little importance with respect to working capacity in this type of community, where malaria is meso-endemic.

The purpose of this study was to determine the lung impact from working within the Libyan quarry industry, and if the length of work impacted the degree of degradation. Eighty three workers from eight silica quarries in the Nafusa Mountains of Libya opted to participate. These quarries were working the upper cretaceous geological structure. Eighty-five individuals who lived in Gharyan City with no affiliation to quarry operations participated as controls. Spirometry variables evaluated were Forced Vital Capacity (FVC), Forced Expiratory Volume at 1.0 second (FEV1), FVC/FEV1 and Peak Expiratory Flow (PEF). Control and exposed groups had no differences in terms of height, weight, or smoking status (p = 0.18, 0.20, 0.98, respectively). Prior to adjustment for other variables, FVC, FEV1, and PEF are all significantly lower in the exposed group (p = 0.003, 0.009, 0.03, respectively). After adjustment for age, height, weight, and smoking status, there remain significant differences between the control and exposed groups for FVC, FEV1, and PEF. This analysis demonstrated that exposure to quarry dust has a detrimental effect on lung function, and that pre-revolution Libyan quarry workers were being exposed. This study shows that any exposure is harmful, as the reduction in lung function was not significantly associated with years of exposure.

The aim of the present study was to evaluate the association between failed smoking cessation and occupation by age stratification among Korean males and provide quantitative evidence of factors associated with failed smoking cessation. The study comprised 3,127 male workers who had attempted smoking cessation during their life time. Data were obtained from the Korea National Health and Nutrition Examination Survey from 2010 to 2012. Participants were stratified by age into two subgroups comprising a younger group (19-40 yr) and an older group (41-60 yr). Multiple logistic regression analyses were used to estimate odds ratios (ORs) for failed smoking cessation. In the younger group, failed smoking cessation was related to the occupational fields "service and sales" and "manual work" compared to "office work" (OR: 2.10, 95% confidence interval (CI): 1.34-3.29; and OR: 1.47, 95% CI: 1.02-2.12, respectively). In the older group, the ORs of failed smoking cessation occupational categories "service and sales" and "manual work" [ref: office workers] were 0.58 (0.40-0.85) and 0.90 (0.66-1.24), respectively. Failed smoking cessation is associated with occupational categories and age stratification. Policy makers need to create tailored anti-smoking policy considering the occupation and the age of the subjects.

Workdays, in-between workdays and the weekend: a diary study on effort and recovery.

Effort-recovery theory (Meijman and Mulder in Handbook of work and organizational psychology, Psychology Press/Erlbaum, Hove, pp 5-33, 1998) proposes that effort expenditure may have adverse consequences for health in the absence of sufficient recovery opportunities. Thus, insight in the relationships between effort and recovery is imperative to understand work-related health. This study therefore focused on the relation between work-related effort and recovery (1) during workdays, (2) in-between workdays and (3) in the weekend. For these three time periods, we compared a group of employees reporting relatively low levels of work-related effort ("low-effort group") and a group of employees reporting relatively high levels of work-related effort ("high-effort group") with respect to (1) activity patterns, (2) the experience of these activity patterns, and (3) health and well-being indicators. Data were collected among university staff members. Participants (N(high-effort group) = 24 and N(low-effort group) = 27) completed a general questionnaire and took part in a 7-day daily diary study covering five weekdays and the following weekend. Differences between the two effort-groups were examined by means of analysis of variance. Compared to the low-effort group, the high-effort group (1) engaged less often in active leisure activities during the week and worked more overtime in the weekend, (2) considered both work and home activities as more effortful, but not as less pleasurable, and (3) reported higher levels of sleep complaints (weekdays only) and fatigue, more preoccupation with work (weekdays only) and lower motivation to start the next workweek during the weekend. Work-related effort is associated with various aspects of work time and (potential) recovery time in-between workdays and in the weekend. High levels of work-related effort are associated with activity patterns that are less beneficial in terms of recovery, with higher effort expenditure during and after work time, and with diminished health and well-being.

Histological, epidemiological and clinical aspects of centroblastic-centrocytic lymphomas subdivided according to the "working formulation".

A group of 424 lymphomas diagnosed as centroblastic-centrocytic lymphomas at the Lymph Node Registry in Kiel was subdivided into small (S), mixed (M) and large (L) cell groups, according to the "working formulation" proposed in a National Cancer Institute sponsored study. Histological epidemiological and clinical parameters were studied. It was found that in group S a follicular growth pattern was most frequent and in group L a follicular and diffuse growth, while group M took an intermediate position. No statistically significant differences were found in respect to epidemiological factors or overall survival. However, in the first 6 years after the diagnosis the survival in group S was better than in group M, but thereafter a reversal occurred. Group L appeared to have the worst survival throughout. Growth pattern and sclerosis were found to be of limited influence on survival within the cytological groups. PMID:6367799

Health care expenditures among working-age adults with physical disabilities: variations by disability spans.

Data on health care costs for working-age adults with physical disabilities are sparse and the dynamic nature of disability is not captured. To assess the effect of 3 types of disability status (persistent disability, temporary disability, and no disability) on health care expenditures, out-of-pocket (OOP) spending, and financial burden. Data from Medical Expenditure Panel Survey panel 12 (2007-2008) were used. Respondents were classified into 3 groups. Medians of average annual expenditures, OOP expenditures, and financial ratios were weighted. The package R was used for quantile regression analyses. Fifteen percent of the working-age population reported persistent disabilities and 7% had temporary disabilities. The persistent disability group had the greatest unadjusted annual medians for total expenditures ($4234), OOP expenses ($591), and financial burden ratios (1.59), followed by the temporary disability group ($1612, $388, 0.71 respectively). The persistent disability group paid approximately 15% of total health care expenditures out-of-pocket, while the temporary disability group and the no disability group each paid 22% out-of-pocket. After adjusting for other factors, quantile regression shows that the persistent disability group had significantly higher total expenditures, OOP expenses, and financial burden ratios (coefficients 1664, 156, 0.58 respectively) relative to the no disability group at the 50th percentile. Results for the temporary disability group show a similar trend except for OOP expenses. People who have disabling conditions for a longer period have better financial protection against OOP health care expenses but face greater financial burdens because of their higher out-of-pocket expenditures and their socioeconomic disadvantages.

This study is aimed at finding out the relationship between long working hours, one of major job stress elements, and hearing impairment in unexposed workers to occupational and environmental noise. This study was performed on 1628 regular, full-time wage workers between the age of 25-64 who indicated in the survey of having no experience of exposure to noise, normal otoscopic findings, and not suffering from diabetes based on the data from the fifth Korea National Health and Nutrition Examination Survey (KNHANES 2010-2012). The average working hours per week was categorized into 40 h and lower group, more than 40 to 48 h group, more than 48 to 60 h group, and more than 60 h group. The groups were defined as suffering from low or high frequencies hearing impairment if the average hearing threshold for 0.5, 1, 2 kHz or 3, 4, 6 kHz in both ears exceeds 25 dB based on the pure tone audiometry. The association between average weekly working hours and hearing impairment was analyzed using logistic regression after gender stratification. The prevalences of low and high frequencies hearing impairment in male workers were 4.3 and 28.6 %, respectively, which were much higher than female's prevalence of 2.7 and 11.1 %. For male workers, no significant association was found between average weekly working hours and low and high frequencies hearing impairment. For female workers, odds ratios (OR) of low and high frequencies hearing impairment were 4.22 (95 % confidence interval (CI) 1.09-16.27) and 4.49 (95 % CI 1.73-11.67), respectively, after controlling for several related factors, such as, age, Body Mass Index (BMI), socio-economic status, health-related behavioral, and occupational characteristics variables, in the final model in the group working more than 60 h compared to the group working 40 h and lower. In addition, a dose-response relationship was observed that ORs of low and high frequencies hearing impairment were increased according to increasing average weekly working hours. The association between long working hours and hearing impairment in both low and high frequencies was significant in Korean female workers with a dose-response relationship. Therefore, the law to change the culture of long working hours should be enacted in order to protect the workers' health and improve the quality of life in Korean workers.

This paper presents the activities and publications of Organisation for Economic Co-operation and Developments (OECD's) Working Group on Harmonisation of Regulatory Oversight in Biotechnology and the Task Force for the Safety of Novel Foods and Feeds. The main outputs of the work are the Series of "consensus documents" of the respective groups. These documents compile information which is intended to be used by those involved in the business of risk/safety assessment. These documents are one means of ensuring the transportability of data amongst authorities. An increasing trend in both the Working Group and Task Force is to consider crop species which are relevant to tropical regions and therefore to countries that are not necessarily members of the OECD. For example, the Working Group has recently published a consensus document on bananas and plantains while the Task Force has published a document on cassava. This trend towards crops of greater interest in the tropics is likely to continue into the future.

The aim of the present study is to explore whether those with Specific Language Impairment (SLI) and dyslexia display distinct or overlapping cognitive profiles with respect to learning outcomes. In particular, we were interested in two key cognitive skills associated with academic performance - working memory and IQ. We recruited three groups of children - those with SLI, those with dyslexia, and a control group. All children were given standardized tests of working memory, IQ (vocabulary and matrix), spelling, and math. The pattern of results suggests that both children with dyslexia and SLI are characterized with poorer verbal working memory and IQ compared to controls, but preserved nonverbal cognitive skills. It appears that that these two disorder groups cannot be distinguished by the severity of their cognitive deficits. However, there was a differential pattern with respect to learning outcomes, where the children with dyslexia rely more on visual skills in spelling, while those with SLI use their relative strengths in vocabulary. These findings can have important implications for how intervention is tailored in the classroom, as disorder-specific support could yield important gains in learning. Copyright © 2017.

The aim of this work was to study the specificity of deficits in linguistic and executive functioning of students with ADHD and with RCD and to determine the profile of deficits in the comorbid group (ADHD+RCD). Participants in the study were 84 students, ages 12-16 years divided into four groups with an equal number of subjects (N= 21): ADHD, RCD, ADHD+RCD and comparison group (without ADHD and without RCD). We measured vocabulary, oral comprehension, lexical access, verbal and visual working memory, inhibition and attention. The results show that the ADHD+RCD group presents the most important linguistic deficits, followed by the RCD group. On the other hand, the three clinical groups (ADHD, RCD and ADHD+RCD) display greater performance problems in working memory than the comparison group, whereas the two groups with ADHD had more problems in attention and inhibition. These results suggest the dissociation of linguistic and executive deficits that affect the RCD group and ADHD group to a greater extent, respectively. Lastly, the comorbid group showed deficits both in language and in executive skills. We discuss the implications of these findings for designing interventions.

In 2012 the International Association of Geodesy (IAG) and the International Astronomical Union (IAU) initiated a process to establish a Joint Working Group (JWG) on theory of Earth rotation with the purpose of promoting the development of improved theories of the Earth rotation which reach the accuracy required to meet the needs of the near future as recommended by, e.g. GGOS, the Global Geodetic Observing System of the IAG. The JWG was approved by both organizations in April 2013 with the chairs being the two authors of this paper. Its structure comprises three Sub Working Groups (SWGs) addressing Precession/Nutation, Polar Motion and UT1, the Numerical Solutions and Validation, respectively. The SWGs should work in parallel for the sake of efficiency, but should keep consistency as an overall goal. This paper offers a view of the objectives and scope of the JWG and reports about its initial activities and plans.

Work poses potential threats to the physical, emotional, economic, and academic health of teenagers. Like their adult coworkers, teenagers face exposure to a variety of health and safety hazards that can lead to injury and illness. Children's increased vulnerability puts them at a high risk of work-related health problems. The aim of this study was to compare growth parameters of working children in contrast to nonworking students, and to compare the frequency of anemia and parasitic infestations among the two groups. A comparative cross-sectional study among 75 working boys in small industrial workshops in Arab Gohaina village in Qaliuobia governorate and 75 students of the same residence was conducted. All children were interviewed and were subjected to physical examination. Their BMI and hemoglobin were measured, and stool samples were examined for parasites. Only 11 and 15% of the workers working children eat vegetables and fruits on daily basis compared with 25 and 49% of students respectively (P<0.001). Mean BMI of the working group was 21.62±2.56 compared with 23.29±3.09 among the students. Students showed more frequency of obesity and overweight than the working group (13.33 and 29.33% compared with 2.67 and 20%, respectively, P=0.009). The hemoglobin level of working children (10.27±0.53 g/dl) was less than that of students (11.31±0.75 g/dl, P<0.001). The frequency of having parasitic infestations among working children was significantly higher than the students (P<0.001). Labor was a factor that negatively affected the health of children. More working children in this village had anemia and parasitic infestations than nonworking ones. It is recommended to pay more attention to health problems among working children, with controlling child labor, especially in hazardous occupations and performing periodic medical examination to monitor their health and development.

Work conditions in industrial production vary substantially between different cultures. In the present study the aims were to identify differences between Swedish and Indonesian assembly industry workers regarding work environment factors, health and job satisfaction, and to find associations between work environment factors, and the health measures. Data were collected by a questionnaire from 326 Swedish and 136 Indonesian assembly industry workers, interviews and from company documents. The prevalence of musculoskeletal symptoms was high in both groups. Stress and psychosomatic symptoms had higher prevalences in the Swedish group, which also rated their work conditions as worse in most respects. Work tasks were physically heavier in Indonesia, but less monotonous and with lower demands on productivity. The Indonesians were more satisfied with their jobs. Physical job demands were associated with musculoskeletal symptoms. Competence development was associated with increased job satisfaction. Conflicts and harassments at work were associated with stress and psychosomatic symptoms. Job pressure, especially deficient planning of the jobs was associated with lower job satisfaction, psychosomatic and stress symptoms in the Swedish group. Implications for job design in the two cultures are presented.

Progress report of the IAU Commission 4 Working Group on Ephemeris Access and the comparison of high accuracy planetary ephemerides

Hilton, J. L.

2012-12-01

In September 2010 IAU Commission 4, Ephemerides, organized a working group to provide a recommendation for a preferred format for solar system ephemerides. The purpose of this recommendation is to provide easy access to a wide range of solar system ephemerides for users. The working group, chaired by Hilton, includes representatives from each of the major planetary ephemeris groups and representatives from the satellite and asteroid ephemeris communities. The working group has tentatively decided to recommend the SPK format developed by the Jet Propulsion Laboratory's Navigation and Ancillary Information Facility for use with its SPICE Toolkit. Certain details, however, must still be resolved before a final recommendation is made by the working group. An update is also provided to ongoing analysis comparing the three high accuracy planetary ephemerides, DE421, EPM2008, and INPOP10a. The principal topics of this update are: replacing the INPOP08 ephemeris with the INPOP10a ephemeris, making the comparisons with respect to DE421 rather than DE405, and comparing the TT - TDB values determined in EPM2008 and INPOP10a with the Fairhead & Bretagnon (1990, A&A, 229, 240) model used in DE421 as T_eph.

Recent work has studied multiple addictions using a matrix measure, which taps multiple addictions through single responses for each type. The present study investigated use of a matrix measure approach among former alternative high school youth (average age = 19.8 years) at risk for addictions. Lifetime and last 30-day prevalence of one or more of 11 addictions reviewed in other work (Sussman, Lisha & Griffiths, 2011) was the primary focus (i.e., cigarettes, alcohol, other/hard drugs, eating, gambling, Internet, shopping, love, sex, exercise, and work). Also, the co-occurrence of two or more of these 11 addictive behaviors was investigated. Finally, the latent class structure of these addictions, and their associations with other measures, was examined. We found that ever and last 30-day prevalence of one or more of these addictions was 79.2% and 61.5%, respectively. Ever and last 30-day co-occurrence of two or more of these addictions was 61.5% and 37.7%, respectively. Latent Class Analysis suggested two groups: a generally Non-addicted Group (67.2% of the sample) and a "Work Hard, Play Hard"-addicted Group that was particularly invested in addiction to love, sex, exercise, the Internet, and work. Supplementary analyses suggested that the single-response type self-reports may be measuring the addictions they intend to measure. We suggest implications of these results for future studies and the development of prevention and treatment programs, though much more validation research is needed on the use of this type of measure.

To study the effect of underground work on cardiovascular system health in coal miners.
 Male coal miners, who received electrocardiographic examinations between June, 2013 and August, 2014 in Hunan Prevention and Treatment Institute for Occupational Diseases to exclude pneumoconiosis, were enrolled for this study (n=3 134). Miners with 2 years or more underground work experience were selected as the exposed group (n=2 370), while miners without underground work experience were selected as the control group (n=764). The prevalence of electrocardiographic abnormalities and the influential factors were compared between the 2 groups.
 The prevalences of electrocardiographic abnormalities, hypertension, heart rate abnormalities and cardiovascular system abnormalities in the exposed group vs the control group were 37.6% vs 25.4%, 20.5% vs 13.4%, 5.7% vs 6.0%, 49.8% vs 35.2%, respectively. The cardiovascular system abnormalities were correlated with the underground work (OR=3.128, 95% CI: 1.969-4.970), the underground work experience (OR=1.205, 95% CI: 1.070-1.358) and the type of works (mining worker OR=1.820, 95% CI: 1.527-2.169; auxiliary worker OR=1.937, 95% CI: 1.511-2.482; other worker OR=3.291, 95%CI: 2.120-5.109).
 Underground work may increase the prevalence of cardiovascular system abnormalities for coal miners. The longer the coal miners work in underground, the higher the risk of the cardiovascular system abnormalities they are.

This study evaluated the diagnostic accuracy of the Work Functioning Impairment Scale (WFun), a questionnaire to detect workers with health problems which affect their work, using an assessment by an occupational health nurse as objective standard. The WFun was completed by 294 employees. The nurse interviewed to assess 1) health problems; 2) effects of health on their work; necessity for 3) treatment, 4) health care instruction, and 5) consideration of job accommodation. The odds ratio in the high work functioning impairment group compared with the low was highly statistically significant with 9.05, 10.26, 5.77, 9.37, and 14.70, respectively. The WFun demonstrated the high detectability with an area under the receiver operating characteristic of 0.75, 0.81, 0.72, 0.79, and 0.83, respectively. This study suggests that the WFun is useful in detecting those who have health problems affecting their work.

To explore associations between work status and multidimensional health indices in a sample of urban Lebanese children. A cross-sectional survey was used to compare 78 male children (aged 10-17 years) working full time in small industrial shops, and a comparison group of 60 non-working male schoolchildren. All children lived and worked or studied in the poor neighbourhoods of three main Lebanese cities. Working children reported frequent abuses. They smoked and dated more than the comparison group. They also reported a higher number of injuries (last 12 months) and recent skin, eye, and ear complaints (last two weeks). Physical examination revealed more changes in their skin and nails, but no differences in height or weight compared to non-working group. A higher blood lead concentration was detected among working children, but no differences in haemoglobin and ferritin. No differences were noted between the two groups of children regarding anxiety, hopelessness, and self-esteem. The drawings of the working children, however, revealed a higher tendency to place themselves outside home and a wider deficit in developmental age when compared to non-working children. Significant differences were found between working and non-working children with respect to physical and social health parameters, but differences were less with regard to mental health. Future research should focus on (1) more sensitive and early predictors of health effects, and (2) long term health effects. The generality of findings to other work settings in the developing world should also be tested.

The purpose of this study was to determine the lung impact from working within the Libyan quarry industry, and if the length of work impacted the degree of degradation. Eighty three workers from eight silica quarries in the Nafusa Mountains of Libya opted to participate. These quarries were working the upper cretaceous geological structure. Eighty-five individuals who lived in Gharyan City with no affiliation to quarry operations participated as controls. Spirometry variables evaluated were Forced Vital Capacity (FVC), Forced Expiratory Volume at 1.0 second (FEV1), FVC/FEV1 and Peak Expiratory Flow (PEF). Control and exposed groups had no differences in terms of height, weight, or smoking status (p = 0.18, 0.20, 0.98, respectively). Prior to adjustment for other variables, FVC, FEV1, and PEF are all significantly lower in the exposed group (p = 0.003, 0.009, 0.03, respectively). After adjustment for age, height, weight, and smoking status, there remain significant differences between the control and exposed groups for FVC, FEV1, and PEF. This analysis demonstrated that exposure to quarry dust has a detrimental effect on lung function, and that pre-revolution Libyan quarry workers were being exposed. This study shows that any exposure is harmful, as the reduction in lung function was not significantly associated with years of exposure. PMID:25961801

Assessment of the discomfort threshold of command board operators in automated productions with respect to its application in professional selection.

Tzaneva, L

The discomfort threshold problem is not yet clear from the audiological point of view. Its significance for work physiology and hygiene is not enough clarified. This paper discussed the results of a study of the discomfort threshold, performed including 385 operators from the State Company "Kremikovtzi", divided into 4 groups (3 groups according to length of service and one control group). The most prominent changes were found in operators with increased tonal auditory threshold up to 45 and over 50 dB with high confidential probability. The observed changes are distributed in 3 groups: 1. increased tonal auditory threshold (up to 30 dB) without decrease of the discomfort threshold; 2. decreased discomfort threshold (with about 15-20 dB) at increased tonal auditory threshold (up to 45 dB); 3. decreased discomfort threshold at increased (over 50 dB) tonal auditory threshold. The auditory scope of the operators, belonging to groups III and IV (with the longest length of service) is narrowed, being distorted for the latter. This pathophysiological phenomenon can be explained by an enhanced effect of sound irritation and the presence of a recruitment phenomenon with possible engagement of the central part of the auditory analyzer. It is concluded that the discomfort threshold is a sensitive indicator for the state of the individual norms for speech-sound-noise discomfort. The comparison of the discomfort threshold with the hygienic standards and the noise levels at each particular working place can be used as a criterion for the professional selection for work in conditions of masking noise effect and its tolerance with respect to achieving the individual discomfort level depending on the intensity of the speech-sound-noise signals at a particular working place.

The objective of this study was to evaluate the effect of root canal preparation with single-file reciprocating systems at different working lengths on the development of apical microcracks using micro-computed tomographic (micro-CT) imaging. Forty extracted human mandibular incisors were randomly assigned to 4 groups (n=10) according to the systems and working length used to prepare the root canals: Group A - WaveOne Gold at apical foramen (AF), Group B - WaveOne Gold 1 mm short of the AF (AF-1 mm), Group C - Unicone (AF) and Group D - Unicone (AF-1 mm). Micro-CT scanning was performed before and after root canal preparation at an isotropic resolution of 14 µm. Then, three examiners assessed the cross-sectional images generated to detect microcracks in the apical portion of the roots. Apical microcracks were visualized in 3, 1, 1, and 3 specimens in groups A, B, C, and D, respectively. All these microcracks observed after root canal preparation already existed prior to instrumentation, and no new apical microcrack was detected. For all groups, the number of slices presenting microcracks after root canal preparation was the same as before canal preparation. Root canal preparation with WaveOne Gold and Unicone, regardless of the working length, was not associated with apical microcrack formation.

In 2001, the Norwegian authorities and major labour market partners signed an agreement regarding 'inclusive working life' (IW), whereby companies that participate are committed to reducing sickness absence. Our main aim was to determine the effect of the IW program and work characteristics by gender on long-term (>8 weeks) sickness absence (LSA). Self-reported data on work characteristics from the Oslo Health Study were linked to registry-based data on IW status, education and LSA. From 2001-2005, 10,995 participants (5,706 women and 5,289 men) aged 30, 40, 45 and 60 years were followed. A Cox regression was used to compute hazard ratios (HR) for LSA risk. The cohort was divided into an IW group (2,733 women and 2,058 men) and non-IW group (2,973/3,231). 43.2% and 41.6% of women and 22.3%/24.3% of men (IW / non-IW, respectively) experienced at least one LSA. In a multivariate model, statistically significant risk factors for LSA were low education (stronger in men), shift work/night work or rotating hours (strongest in men in the non-IW group), and heavy physical work or work involving walking and lifting (men only and stronger in the non-IW group). Among men who engaged in shift work, the LSA risk was significantly lower in the IW group. Our results could suggest that IW companies that employ many men in shift work have implemented relevant efforts for reducing sickness absence. However, this study could not demonstrate a significant effect of the IW program on the overall LSA risk.

Employees in alumina refineries are known to be exposed to a number of potential respiratory irritants, particularly caustic mist and bauxite and alumina dusts. To examine the prevalence of work related respiratory symptoms and lung function in alumina refinery employees and relate these to their jobs. 2964 current employees of three alumina refineries in Western Australia were invited to participate in a cross sectional study, and 89% responded. Subjects were given a questionnaire on respiratory symptoms, smoking, and occupations with additional questions on temporal relations between respiratory symptoms and work. Forced expiratory volume in 1 second (FEV(1)) and forced vital capacity (FVC) were measured with a rolling seal spirometer. Atopy was assessed with prick skin tests for common allergens. Associations between work and symptoms were assessed with Cox's regression to estimate prevalence ratios, and between work and lung function with linear regression. Work related wheeze, chest tightness, shortness of breath, and rhinitis were reported by 5.0%, 3.5%, 2.5%, and 9.5% of participants respectively. After adjustment for age, smoking, and atopy, most groups of production employees reported a greater prevalence of work related symptoms than did office employees. After adjustment for age, smoking, height, and atopy, subjects reporting work related wheeze, chest tightness, and shortness of breath had significantly lower mean levels of FEV(1) (186, 162, and 272 ml respectively) than subjects without these symptoms. Prevalence of most work related symptoms was higher at refinery 2 than at the other two refineries, but subjects at this refinery had an adjusted mean FEV(1) >60 ml higher than the others. Significant differences in FVC and FEV(1)/FVC ratio, but not FEV(1), were found between different process groups. There were significant differences in work related symptoms and lung function between process groups and refineries, but these were mostly not consistent. Undefined selection factors and underlying population differences may account for some of these findings but workplace exposures may also contribute. The differences identified between groups were unlikely to be clinically of note.

2017-10-01

Body silhouette 3D measurements need to be performed separately in each country due to significant ethnic differences in body silhouette which preclude the transfer of European data to particular countries. Systematic research allows to update information on the population body silhouette and body proportions as well as select the size changes possible to implement in clothing construction modifications. The diversity in body silhouettes and sizes as well as the issue of clothing fitting encourage clothing producers to provide work wear clothing based on individual measurements of the end users’ bodies. In the framework of the carried research, the group of construction workers was selected as the target group of the analysed work wear clothing users. 42 construction workers, men only, were measured. The body silhouette measurement process was non-contact and was carried out with the use of 3D body scanner. The collected data on the body silhouette allowed to select sizes used to construct the work wear clothing and identify the clothing size. The selected measurement points of the body silhouette underwent statistical analysis to determine the distribution of random variables, here body sizes. The variables distribution characteristics were calculated. On that basis, the fitting appraisal of work wear clothing with respect to the size of the finished product corresponding to the adequate size of individually measured worker/end user was performed. The size overview of the work wear clothing used by the specific professional group and the appraisal of the size fitting to the body silhouette took into consideration the work wear clothing ergonomic functionality with respect to the body posture when performing the tasks, design and clothing construction. The analysis based on the currently gathered end users’ remarks and objections concerning the clothing fitting and performed body silhouette measurements allows to modify the existing work wear clothing for the selected group of end users. The research was aimed at the improvement of the work wear clothing fitting thanks to personalization based on individual body measurements at the stage of construction design.

NASA's Earth Science Data Systems Working Groups (ESDSWG) was created over 10 years ago. The role of the ESDSWG is to make recommendations relevant to NASA's Earth science data systems from users' experiences. Each group works independently focusing on a unique topic. Participation in ESDSWG groups comes from a variety of NASA-funded science and technology projects, including MEaSUREs and ROSS. Participants include NASA information technology experts, affiliated contractor staff and other interested community members from academia and industry. Recommendations from the ESDSWG groups will enhance NASA's efforts to develop long term data products. The Airborne Metadata Working Group is evaluating the suitability of the current Common Metadata Repository (CMR) and Unified Metadata Model (UMM) for airborne data sets and to develop new recommendations as necessary. The overarching goal is to enhance the usability, interoperability, discovery and distribution of airborne observational data sets. This will be done by assessing the suitability (gaps) of the current UMM model for airborne data using lessons learned from current and past field campaigns, listening to user needs and community recommendations and assessing the suitability of ISO metadata and other standards to fill the gaps. The Time Series Working Group (TSWG) is a continuation of the 2015 Time Series/WaterML2 Working Group. The TSWG is using a case study-driven approach to test the new Open Geospatial Consortium (OGC) TimeseriesML standard to determine any deficiencies with respect to its ability to fully describe and encode NASA earth observation-derived time series data. To do this, the time series working group is engaging with the OGC TimeseriesML Standards Working Group (SWG) regarding unsatisfied needs and possible solutions. The effort will end with the drafting of an OGC Engineering Report based on the use cases and interactions with the OGC TimeseriesML SWG. Progress towards finalizing recommendations will be presented at the meeting.

Objectives This study aimed to evaluate the effect of a stress management intervention (SMI) on lasting return to work (RTW) among patients with work-related stress complaints. Methods Sickness benefit departments from three local municipalities referred patients on sick leave with work-related adjustment disorders or mild depression to the Department of Occupational Medicine, Regional Hospital West Jutland. A 2× randomization procedure allocated patients into one of three groups: intervention (N=58), control A (which received a clinical assessment; N=56), or control B (no assessment; N=49). Treatment comprised individual work-focused cognitive behavioral therapy (CBT) with an optional workplace intervention. The outcome was time until lasting RTW (16 and 44 weeks follow-up) using register data. Results Median number of weeks until lasting RTW was 15, 19, and 32 for the intervention group, control A, and control B respectively. However, for group B, clinical assessment was not part of the inclusion process, which may have introduced selection bias. In the fully-adjusted Cox regression model, the intervention group exhibited significantly faster lasting RTW at 44 weeks; hazard ratio (HR) 1.57 [95% confidence interval (95% CI) 1.01-2.44] relative to control group A, with a non-significant trend evident at 16 weeks; HR 1.70 (95% CI 0.94-3.10), when controlling for age, gender, occupation, sick leave during previous year, full or partial sick leave, and diagnosis. Unadjusted analyses remained directionally consistent but were reduced to marginal significance. Conclusions There was a tendency towards faster lasting RTW in the intervention group compared to control A, which received clinical assessment, in all analyses. The intervention group returned to work about 4 weeks earlier than control A, which could translate into substantial financial gains.

There is controversy concerning the management of the remaining cavity after the evacuation of a cyst in patients who have undergone surgical operation for liver hydatidosis. This study compares the results of capitonnage and tube drainage of the remaining cavity. In this retrospective study, participants were selected from two groups of patients with a liver hydatid cyst who underwent capitonnage or tube drainage from 2004 to 2012. The patients were followed for 6-24 months. The data of age, sex, involved liver lobe, size of the cyst, complications, drain duration, and hospital stay were analyzed. Participants included 155 patients consisting of 96 (61.94%) females and 59 (38.06%) males. Most cysts were in the right lobe, and the most common diameter of the cysts was greater than 10 cm. Capitonnage was performed on 90 (58.06%) patients and the tube drainage procedure was performed on the remaining 65 (41.94%) patients. In the tube drainage group and the capitonnage group, the operative times were 2.21 ± 0.65 hours and 2.53 ± 0.35 hours, respectively; the hospital stays were 5.695 ± 3.37 days and 4.43 ± 2.96 days, respectively; the drain duration was 9.2 ± 1.7 days and 2.1 ± 0.4 days, respectively; and the time to return to work was 14.7 ± 2.3 days and 8.3 ± 10.4 days, respectively. All variables were statistically significant, except for the operative time. Cavity infection and biliary fistula were identified in three patients and six patients, respectively, in the tube drainage group and identified in two patients and three patients, respectively, in the capitonnage group. This difference was not statistically significant. This study demonstrated that capitonnage versus the tube drainage method may result in a shorter hospital stay, decreased time to return to work, and low rate of morbidity and complications.

Objective To assess changes in work productivity in patients who have achieved response using etanercept (ETN) 50 mg+methotrexate (MTX) (phase I) are randomised to ETN 25 mg+MTX versus MTX versus placebo (phase II) and then withdrawn from treatment (phase III). Methods Patients included in the analysis were in employment entering phase II of the PRIZE trial and had one or more follow-ups. Phase II was a 39-week, randomised and double-blind comparison of the 3 dose-reduction treatments. Phase III was a 26-week observational study where treatment was withdrawn. The Valuation of Lost Productivity was completed approximately every 13 weeks to estimate productivity impacts from a societal perspective. Results A total of 120 participants were included in our analyses. During phase II, ETN25+MTX or MTX improved paid work productivity by over 100 hours compared with placebo, amounting to a gain of €1752 or €1503, respectively. ETN25+MTX compared with placebo gains €1862 in total paid/unpaid productivity. At week 52, the 3-month paid work productivity loss was 21.8, 12.8 and 14.0 hours, respectively. The productivity loss increased at week 64 from week 52, dropped at week 76 for all treatment groups and then continued rising after week 76 for the placebo group (71.9 hours at week 91) but not for the other 2 groups (21.9 hours for ETX25+MTX and 27.6 hours for MTX). Conclusions The work productivity gain in phase I as a result of ETN50+MTX was marginally lost in the dose-reduction treatment groups, ETN25+MTX and MTX, but substantially lost in the placebo group during phase II.

Laparoscopic myomectomy offers women many benefits over conventional open surgery, including an expedited recovery and return to employment. Our study evaluates the time taken for women to return to work after laparoscopic myomectomy and identifies factors prolonging recovery to > 8 weeks. We prospectively evaluated 94 women undergoing laparoscopic myomectomy by a single surgeon between January 2012 and March 2015. Women had standardized preoperative counseling and completed a validated return to work questionnaire 3 months postoperatively via telephone, post or in clinic. In all, 71/94 (75.5%) women completed the questionnaire. Results were analyzed comparing women who returned to work in ≤ 8 weeks [43/71 (60.6%)] with those who returned > 8 weeks postoperatively [28/71 (39.4%)]. A higher proportion of Asian and Caucasian women returned to work in ≤ 8 weeks (24/29) compared with black African and Caribbean women (19/42) (p = 0.003). Mean number of fibroids removed (2.59 and 5.75, respectively) was the only significantly differing factor between the two groups (p = 0.004). There was a significant difference in body mass index (BMI) and time to return to normal activity between the ≤ 8-week and > 8-week groups (p = 0.027, p = 0.011, respectively). Logistic regression analysis demonstrated that BMI and time to return to normal activity were the only factors prolonging recovery to > 8 weeks (p = 0.039, p = 0.015, respectively). Time to return to normal activity and BMI significantly influenced the time taken for women to work after laparoscopic myomectomy. Further data would support clinicians in counseling women appropriately and optimizing their postoperative return to employment. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

The Formalism of Quantum Mechanics Specified by Covariance Properties

The known methods, due for instance to G.W. Mackey and T.F. Jordan, which exploit the transformation properties with respect to the Euclidean and Galileian group to determine the formalism of the Quantum Theory of a localizable particle, fail in the case that the considered transformations are not symmetries of the physical system. In the present work we show that the formalism of standard Quantum Mechanics for a particle without spin can be completely recovered by exploiting the covariance properties with respect to the group of Euclidean transformations, without requiring that these transformations are symmetries of the physical system.

The study of emotional and personality characteristics of patients with hypertension in the workplace (HW) and comparative assessment of the effectiveness of antihypertensive therapy in these patients. The study included 170 patients c hypertensive disease stage II, 1-2-th degree, aged 32-52 years, including 85 patients with and 85 patients without WAH, and 82 healthy subjects matched for age and sex. To carry out simulation of the situation of emotional intensity (level of claims assessment process - UE) and a modified version of the test Rosenzweig. Patients with WAH were randomized into 2 groups: patients of group 1 received bisoprolol, 2nd group -eprosartan. If target blood pressure (BP) in 2 weeks, all patients were added indapamide retard. At baseline and after 16 weeks of treatment was carried out daily monitoring of blood pressure and the working day. When modeling a situation of emotional intensity in patients with WAP become, compared with patients without a healthy and WAH, revealed (1) marked increase in systolic blood pressure - 16.1, 4.1 and 3.0 mmHg, respectively (p <0,001 ), (2) the dominance of motivation "avoid failure" (UP underestimated in 34.1% of cases, unformed UP - in 21.2% of cases, healthy - 14.6% and 3.7% of cases, cootvetstvenno, p<0,001 in patients without WAH - 20% and 11.8%, respectively, p<0,05). Patients with WAP become different from normal was significantly (p<0.05) the number of the selected blshim emotionally meaningful situations (9.7 and 7.8, respectively) and emotional descriptors (11 and 7, respectively). Patients with WAH differ significantly (p<0,05) more frequent than in healthy, the use of ineffective strategies of emotion regulation in an emotionally meaningful situations: the suppression of the expression of emotions (38.3 and 20.3%, respectively), rumination and disasterization (19 and 11.8%, respectively) and more rare - high performance: sequential actualization of new meanings (25.7 and 31.7%, respectively) and the strategy of interactive subject-subject transformations (12.6 and 25.2%, respectively). After 16 weeks of treatment showed a significant (p<0,001) reduction of blood pressure in the 1st and 2nd groups. The number of patients achieving target blood pressure, at 2, 4 and 6 weeks, respectively, was as follows: 14 in the bisoprolol group and 93 (100%), in the eprosartan group - 0, 52 (100%). Both groups showed significant (p <0,001) reduction in mean daytime and nighttime blood pressure in the weekdays and weekends. In the group of bisoprolol showed a significant (p <0,01) higher average daily decrease in systolic blood pressure in the working day, compared with eprosartan group (26.2 and 19.3 mm Hg, respectively). Patients with WAP become emotionally meaningful situations frequently resorted to repression of emotions, choose the inefficient strategies of emotion regulation, they noted the expressed reaction of BP in response to the emotional burden. Antihypertensive therapy based on bisoprolol, is highly effective and has advantages over circuit-based therapy with eprosartan.

Transgender patients have particular needs with respect to demographic information and health records; specifically, transgender patients may have a chosen name and gender identity that differs from their current legally designated name and sex. Additionally, sex-specific health information, for example, a man with a cervix or a woman with a prostate, requires special attention in electronic health record (EHR) systems. The World Professional Association for Transgender Health (WPATH) is an international multidisciplinary professional association that publishes recognized standards for the care of transgender and gender variant persons. In September 2011, the WPATH Executive Committee convened an Electronic Medical Records Working Group comprised of both expert clinicians and medical information technology specialists, to make recommendations for developers, vendors, and users of EHR systems with respect to transgender patients. These recommendations and supporting rationale are presented here. PMID:23631835

Early leaving of workplace by work forces is one of the fundamental problems worldwide. Maintenance and enhancement of employees work ability are important for raising productivity. This study investigated the relationship between work ability index and physical working conditions and was carried out in 2013 on 641 workers at a manufacturing plant in Tehran. Work ability was assessed by the questionnaire of work ability index and the participants were classified into four work ability groups of poor, moderate, good, and excellent. Physical working conditions were evaluated by the MUSIC-Norrtalje questionnaire and the participants were classified into two groups with proper and poor physical working conditions. The mean score of work ability questionnaire was 42.40; and 2.5% (16 persons), 9.2% (59 persons), 38.2% (245 persons), and 50.1% (321 persons) of the participants were in poor, moderate, good, and excellent work ability groups, respectively. The mean score of physical working conditions questionnaire was 20.06. The results of logistic regression analysis showed that even after adjusting the confounding variables, a significant correlation existed between work ability and physical working conditions (p < 0.05). According to the results of this study, there may be a correlation between physical working conditions such as awkward postures, repetitive movements, load lifting, exposure to whole body vibration and so on with work ability. Therefore it seems that enhancement of the quality of physical working conditions may increase work ability.

The Redesigning Daily Occupations (ReDO™) work rehabilitation method has been found effective, compared with care as usual (CAU), for women with stress-related disorders. To conduct a long-term follow-up of former ReDO™ and CAU participants with respect to sick leave, well-being and everyday occupations 3-4 years after completed work rehabilitation. Forty-two women in each group participated. An index day was decided to estimate sick-leave rate, retrieved from register data. Fifty-five women also participated in a telephone interview addressing well-being, everyday occupations and life events. Both groups had reduced their sick-leave rate further, but no difference between the groups was established. The ReDO™ women perceived a better balance in the work domain of everyday occupations, whereas the CAU group reported more over-occupation. No differences were found on well-being. The groups had experienced similar important life events, affecting the women's work and private lives. Previous stress and anxiety predicted sick leave at the long-term follow-up. Although the ReDO™ intervention had speeded up return to work in the immediate follow-up perspective, the CAU had caught up in the longer term. Still, the ReDO™ women exhibited better balance in the work domain.

In 546 officials the arterial blood pressure was measured twice at the beginning and at the end of a working day, filling also an inquiry form. As hypertension systolic BP over 160 mm Hg (21.3 kPa) or more, and diastolic BP 96 mm Hg (12.7 kPa) or more were accepted. In 90 subjects (16.5%) above normal pressure values were found. Hypertension had been diagnosed previously in 50 subjects in this group (55.5%) but only 13 of them (26%) were treated systematically. Excessive stress of work was complained of by 62.6% of the subjects. Increased blood pressure was found significantly more frequently in the group perceiving excessive stress of work (19.9%) as compared to those not experiencing this stress (10.8%, p less than 0.1). In the group in managerial posts these proportions were 24.8% and 14.4% respectively (p less than 0.1). Blood pressure rise to abnormal levels during the working day occurred also significantly more frequently in the group experiencing it this was noted only in 1.6% of cases (p less than 0.5). The knowledge of own hypertension was very low in this group. These results indicate the necessity of increasing prophylactic measures in the form of greater frequency of control measurements of the blood pressure, better health education, and limitation of stress situations in working environment.

To evaluate the efficacy and cleaning ability of Hedstrom files, and ProTaper retreatment instruments in removing gutta-percha from root canals with and without xylene as solvent. Sixty extracted single rooted human teeth were selected and decoronated, straight access established working length determined 1 mm short of canal, chemomechanical preparation done and obturated with guttapercha and AH plus sealer. Samples were stored for 1 week in humidifier divided into four groups of 15 teeth each. • Group I: Hedstrom files without xylene. • Group II: Hedstrom files with xylene. • Group III: ProTaper retreatment instruments without xylene. • Group IV: ProTaper retreatment instruments with xylene. and the following criteria were assessed - Time taken for initial plunge of instrument into guttapercha. - Time taken for complete removal of gutta-percha to reach working length - Ability of H files and ProTaper retreatment files with/ without xylene to remove gutta-percha in coronal, middle and apical 1/3 of canal. The teeth were grooved in labiolingual cross section, observed under a steromicroscope and scored according to gutta-percha debris left in the canal. Results were evaluated using ANOVA test and multiple comparisons done using Scheffe test. The least time to reach working length was found with group IV followed by groups III, II and group I respectively. Also the fastest way to remove maximum gutta-percha was group IV followed by groups III, II, and I respectively with a statistically significant difference among all groups. Apical 1/3 has more amount of remaining gutta-percha debris than middle and coronal 1/3 in all groups. The amount of gutta-percha debris in apical 1/3 was least in group IV followed by groups III, II and I respectively. The better performance of ProTaper rotary instruments has been attributed to their special flute design which tends to pull gutta-percha coronally directing it toward orifice. Also the movements of engine driven instruments produce frictional heat which plasticises gutta-percha and aids in easy removal. Apical third of root canals showed more guttapercha debris compared to coronal and middle 1/3 and has been attributed to the greater anatomic variability and difficulty of instrumentation in the apical area. The existence of deep groves and depressions on dentine walls in this apical 1/3 make them less instrumented areas as it did be difficult to direct the file against the extreme root canal wall. The fastest technique to remove gutta-percha and the shortest time to reach working length was observed with ProTaper retreatment instruments with xylene followed by ProTaper retreatment files without xylene and Hedstrom files without xylene. After instrumentation for removal of gutta-percha, apical third was found to have more debris compared to coronal and middle 1/3 of the root canal.

The purpose of this study was to compare the effects of a water + electrolyte solution versus plain water on changes in drinking behaviors, hydration status, and body temperatures during wildfire suppression. Eight participants consumed plain water, and eight participants consumed water plus an electrolyte additive during 15 hours of wildfire suppression. Participants wore a specially outfitted backpack hydration system equipped with a digital flow meter system affixed inline to measure drinking characteristics (drinking frequency and volume). Body weight and urine-specific gravity were collected pre- and postshift. Ambient, core, and skin temperatures were measured continuously using a wireless system. Work output was monitored using accelerometry. There were no differences between groups for body weight, drinking frequency, temperature data, activity, or urine-specific gravity (1.019 +/- 0.007 to 1.023 +/- 0.010 vs. 1.019 +/- 0.005 to 1.024 +/- 0.009 for water and water + electrolyte groups pre- and postshift, respectively; P < .05). There was a main effect for time for body weight, demonstrating an overall decrease (78.1 +/- 13.3 and 77.3 +/- 13.3 kg pre- and postshift, respectively; P < .05) across the work shift. The water group consumed more total fluid (main effect for treatment) than the water + electrolyte group (504 +/- 472 vs. 285 +/- 279 mL.h(-1) for the water and water + electrolyte groups, respectively; P < .05). The addition of an electrolyte mixture to plain water decreased the overall fluid consumption of the water + electrolyte group by 220 mL.h(-1) (3.3 L.d(-1)). Supplementing water with electrolytes can reduce the amount of fluid necessary to consume and transport during extended activity. This can minimize carrying excessive weight, possibly reducing fatigue during extended exercise.

Background and Aims: Recent work has studied multiple addictions using a matrix measure, which taps multiple addictions through single responses for each type. Methods: The present study investigated use of a matrix measure approach among former alternative high school youth (average age = 19.8 years) at risk for addictions. Lifetime and last 30-day prevalence of one or more of 11 addictions reviewed in other work (Sussman, Lisha & Griffiths, 2011) was the primary focus (i.e., cigarettes, alcohol, other/hard drugs, eating, gambling, Internet, shopping, love, sex, exercise, and work). Also, the co-occurrence of two or more of these 11 addictive behaviors was investigated. Finally, the latent class structure of these addictions, and their associations with other measures, was examined. Results: We found that ever and last 30-day prevalence of one or more of these addictions was 79.2% and 61.5%, respectively. Ever and last 30-day co-occurrence of two or more of these addictions was 61.5% and 37.7%, respectively. Latent Class Analysis suggested two groups: a generally Non-addicted Group (67.2% of the sample) and a “Work Hard, Play Hard”-addicted Group that was particularly invested in addiction to love, sex, exercise, the Internet, and work. Supplementary analyses suggested that the single-response type self-reports may be measuring the addictions they intend to measure. Discussion and Conclusions: We suggest implications of these results for future studies and the development of prevention and treatment programs, though much more validation research is needed on the use of this type of measure.

cThis study examined the interactive effect of management by group goals and job interdependence on employee's activities in terms of task and contextual performance. A survey was conducted among 140 Japanese employees. Results indicated that management by group goals was related only to contextual performance. Job interdependence, however, had a direct effect on both task and contextual performance. Moreover, moderated regression analyses revealed that for work groups requiring higher interdependence among employees, management by group goals had a positive relation to contextual performance but not to task performance. When interdependence was not necessarily required, however, management by group goals had no relation to contextual performance and even negatively impacted task performance, respectively. These results show that management by group goals affects task and contextual performance, and that this effect is moderated by job interdependence. This provides a theoretical extension as well as a practical application to the setting and management of group goals.

To evaluate the effect of age on the diagnostic assessment of women with severe cervical intraepithelial neoplasia (CIN). This retrospective observational study included 338 consecutive women with a diagnosis of CIN3 on cone specimen. Patients were divided into three groups according to age: < 35 years (Group A), 35-49 years (Group B), and ≥ 50 years (Group C). Clinical and colposcopic variables were compared, and human papillomavirus (HPV) genotype distribution was measured. The most common HPV genotype was HPV-16 (63.65%), followed by HPV-33 (7%), HPV-18 (6.2%), and HPV-31 (5.4%). The rate of the following high-grade lesion predictors was lower in Group C than in Groups A and B: HPV-16 infections (55.9% vs. 75% vs. 70.9%, respectively, p = 0.022); high-grade colposcopic impression (29.4% vs. 51.8% vs. 51.7%, respectively, p < 0.0001); and high-grade cytological changes (30.9% vs. 56.2% vs. 45.4%, respectively, p = 0.025). An endocervical lesion location was more frequent in Group C than in Groups A and B (55.6% vs. 6.8% vs. 11.8%, respectively, p < 0.0001). Women aged 50 years and older with CIN3 showed a significant reduction of high-grade lesion predictors along with physiological confounding cervical changes (transformation zone type 3 and endocervical lesion location). The diagnostic work-up of cervical lesions in older women should provide their potential consideration as a special population.

Although the clinical requirements of health care delivery imply the need for interdisciplinary management teams to work together to promote frontline learning, such interdisciplinary, learning-oriented leadership is atypical. We designed this study to identify behaviors enabling groups of diverse managers to perform as learning-oriented leadership teams on behalf of quality and safety. We randomly selected 12 of 24 intact groups of hospital managers from one hospital to participate in a Safety Leadership Team Training program. We collected primary data from March 2008 to February 2010 including pre- and post-staff surveys, multiple interviews, observations, and archival data from management groups. We examined the level and trend in frontline perceptions of managers' learning-oriented leadership following the intervention and ability of management groups to achieve objectives on targeted improvement projects. Among the 12 intervention groups, we identified higher- and lower-performing intervention groups and behaviors that enabled higher performers to work together more successfully. Management groups that achieved more of their performance goals and whose staff perceived more and greater improvement in their learning-oriented leadership after participation in Safety Leadership Team Training invested in structures that created learning capacity and conscientiously practiced prescribed learning-oriented management and problem-solving behaviors. They made the time to do these things because they envisioned the benefits of learning, valued the opportunity to learn, and maintained an environment of mutual respect and psychological safety within their group. Learning in management groups requires vision of what learning can accomplish; will to explore, practice, and build learning capacity; and mutual respect that sustains a learning environment.

Given the persistent disparity in the advancement of women compared with men faculty in academic medicine, it is critical to develop effective interventions to enhance women's careers. We carried out a cluster-randomized, multifaceted intervention to improve the success of women assistant professors at a research-intensive medical school. Twenty-seven departments/divisions were randomly assigned to intervention or control groups. The three-tiered intervention included components that were aimed at (1) the professional development of women assistant professors, (2) changes at the department/division level through faculty-led task forces, and (3) engagement of institutional leaders. Generalized linear models were used to test associations between assignment and outcomes, adjusting for correlations induced by the clustered design. Academic productivity and work self-efficacy improved significantly over the 3-year trial in both intervention and control groups, but the improvements did not differ between the groups. Average hours worked per week declined significantly more for faculty in the intervention group as compared with the control group (-3.82 vs. -1.39 hours, respectively, p = 0.006). The PhD faculty in the intervention group published significantly more than PhD controls; however, no differences were observed between MDs in the intervention group and MDs in the control group. Significant improvements in academic productivity and work self-efficacy occurred in both intervention and control groups, potentially due to school-wide intervention effects. A greater decline in work hours in the intervention group despite similar increases in academic productivity may reflect learning to "work smarter" or reveal efficiencies brought about as a result of the multifaceted intervention. The intervention appeared to benefit the academic productivity of faculty with PhDs, but not MDs, suggesting that interventions should be more intense or tailored to specific faculty groups.

The purpose of this study was to explore the experiences of family physicians in primary care obstetrical groups. Using a qualitative approach, in-depth interviews were conducted with 12 Edmonton family physicians who participated in primary care obstetrical groups. Experiences with respect to several aspects of group obstetrical practice were examined including advantages and challenges of primary care obstetrical groups, provision of patient care by a group, fit with other work commitments, and sustainability of the groups. Study data were audiotaped and transcribed verbatim. Independent and team analysis was iterative and interpretive. Primary care obstetrical groups were found to preserve a family physician's enjoyment of obstetrics and allowed for continuity of care. They afforded work-life balance, allowed for collaboration, and provided support and a social network for group members. Such groups were found to facilitate short-term family physician absences, although long-term absences (such as maternity leaves) were considered challenging. Participants described conflict within primary care obstetrical groups and considered sustainability to be a challenge. Family physicians' continued involvement in obstetrics could be facilitated by their participation in primary care obstetrical groups.

Objectives The aim of the study was to assess the effectiveness of the use of part-time sick leave at the early (first 12 weeks) stage of work disability due to mental disorder or musculoskeletal disease on sustained return to work (RTW) and overall work participation. Methods In a nation-wide register-based quasi-experimental study, we compared sustained RTW (ie, ≥28 consecutive days at work) and 2-year work participation between the part- and full-time sickness absence (SA) benefit groups (N=1878 in each group) using propensity-score matching. Persons who received partial or full SA benefit due to musculoskeletal diseases or mental disorders between January 1, 2010 and December 31, 2011 were eligible as cases or controls, respectively. Results A higher proportion showed sustained RTW after part- compared to full-time sick leave [absolute risk difference 8.0%, 95% confidence interval (95% CI) 5.3-10.9]. Moreover, the proportion of time at work was at a 10.5% higher level in the part- compared to full-time sick leave group. The prevalence of full disability retirement was almost three-fold among the full- compared to part-time sick leave group, whereas partial disability retirement was 4.5-fold more prevalent in the part- compared to full-time sick leave group. Conclusions The use of part-time sick leave during the first three months of SA enhances RTW and overall work participation during two years among persons with mental disorders and musculoskeletal diseases. The prescription of part-time sick leave can be recommended at an early stage of work disability.

This study aimed to determine physical performance criteria of different occupational groups by investigating physical activity and energy expenditure in healthy Swiss employees in real-life workplaces on workdays and non-working days in relation to their aerobic capacity (VO2max). In this cross-sectional study, 337 healthy and full-time employed adults were recruited. Participants were classified (nine categories) according to the International Standard Classification of Occupations 1988 and merged into three groups with low-, moderate- and high-intensity occupational activity. Daily steps, energy expenditure, metabolic equivalents and activity at different intensities were measured using the SenseWear Mini armband on seven consecutive days (23 hours/day). VO2max was determined by the 20-meter shuttle run test. Data of 303 subjects were considered for analysis (63% male, mean age: 33 yrs, SD 12), 101 from the low-, 102 from the moderate- and 100 from the high-intensity group. At work, the high-intensity group showed higher energy expenditure, metabolic equivalents, steps and activity at all intensities than the other groups (p<0.001). There were no significant differences in physical activity between the occupational groups on non-working days. VO2max did not differ across groups when stratified for gender. The upper workload limit was 21%, 29% and 44% of VO2max in the low-, moderate- and high-intensity group, respectively. Men had a lower limit than women due to their higher VO2max (26% vs. 37%), when all groups were combined. While this study did confirm that the average workload limit is one third of VO2max, it showed that the average is misrepresenting the actual physical work demands of specific occupational groups, and that it does not account for gender-related differences in relative workload. Therefore, clinical practice needs to consider these differences with regard to a safe return to work, particularly for the high-intensity group. PMID:27136206

To explore the preventing effects of TGF-beta1 antibody (TGF-beta1Ab) compounded with fibrin glue (FG) on postoperative adhesions of flexor tendon. Seventy-two Leghorn chickens were randomly divided into 4 groups (groups A, B, C and D), 18 chickens for each group, and the long flexor tendons of the 3rd and 4th toes in zone II of all chickens were transversed and sutured with the 4-strand cruciate repair technique to make defect models. In group A, 0.2 mL TGF-beta1 Ab was applied at repair site. In group B, 0.2 mL FG was applied at repair site. In group C, 0.2 mL TGF-beta1Ab and FG was applied at repair site. In group D, 0.2 mL normal sodium was applied at repair site. At 1, 3 and 8 weeks after operation, the tendons of 6 chickens in each group were harvested for morphological and histological evaluation. Six specimens of each group were obtained for biomechanical test at 3 and 8 weeks. The gross-observation showed that the differences in grading of tendon adhesion were not significant among 4 groups at 1 week after operation (P > 0.05), but the differences were significant between groups A, B, D and group C at 3 and 8 weeks after operation (P < 0.05). Histological observation showed that collagen fibers arranged irregularly in groups A, B and D, but arranged regularly in group C at 3 and 8 weeks' after operation. At 3 weeks after operation the gliding excursion ratio of the tendon in groups A, B, C and D were 0.45 +/- 0.05, 0.40 +/- 0.10, 0.79 +/- 0.09 and 0.25 +/- 0.07 respectively; the simulated active flexion ratio were 0.61 +/- 0.02, 0.67 +/- 0.03, 0.91 +/- 0.03 and 0.53 +/- 0.04 respectively; the work of flexion were (18.00 +/- 0.77), (17.80 +/- 1.13), (27.60 +/- 1.73) and (15.60 +/- 1.27) degrees/N respectively. There were significant differences between group C and other three groups (P < 0.05). The tendon anastomosis breaking strength were (14.2 +/- 1.9), (15.2 +/- 2.2), (16.0 +/- 2.2) and (14.7 +/- 2.7) N, showing no significant differences among 4 groups (P > 0.05). At 8 weeks after operation, the gliding excursion ratio of the tendon in groups A, B, C and D were 0.45 +/- 0.07, 0.43 +/- 0.08, 0.80 +/- 0.09 and 0.29 +/- 0.05 respectively; the simulated active flexion ratio were 0.61 +/- 0.02, 0.63 +/- 0.03, 0.92 +/- 0.03 and 0.53 +/- 0.03 respectively, the work of flexion were (18.30 +/- 0.84), (18.60 +/- 0.80), (27.90 +/- 1.24) and (15.30 +/- 0.75) degrees/N respectively. There were significant differences between group C and other three groups (P < 0.05). The tendon anastomosis breaking strength were(51.9 +/- 3.0), (51.4 +/- 1.4), (53.3 +/- 1.3) and (52.3 +/- 2.2) N, showing no significant differences among 4 groups (P > 0.05). TGF-beta1Ab compounded with FG could significantly prohibit the formation of fibrous adhesions without interfering with the healing process.

The goal of this work is to study the existence of quasi-periodic solutions to nonlinear beam equations with a multiplicative potential. The nonlinearity is required to only finitely differentiable and the frequency is along a pre-assigned direction. The result holds on any compact Lie group or homogeneous manifold with respect to a compact Lie group, which includes standard torus Td, special orthogonal group SO (d), special unitary group SU (d), spheres Sd and the real and complex Grassmannians. The proof is based on a differentiable Nash-Moser iteration scheme.

To evaluate the effect of health education on prevention from schistosome infection in engineering construction workers in Poyang Lake area. The workers for constructing "De Chang" highway in Poyang Lake area were divided randomly into an experiment group and a control group, "health education + protective skill training" was carried out in the experiment group, whereas, no intervention was implemented in the control group. In the experiment group, the awareness rates of schistosomiasis control knowledge were 7.96% and 96.39% before and after the intervention, respectively; the rates of contacting infested water were 100% and 1.77% pre- and post-intervention, respectively; the work protective rates increased from zero before the intervention to 100% after the intervention; there was no person infected with schistosome after the intervention. However, in the control group, all the indexes above-mentioned had no significant changes. The intervention model "health education + protective skill training", can effectively prevent from schistosome infection in engineering construction workers in Poyang Lake area.

Half of a $10,000 grant was given by the International Planned Parenthood Federation (IPPF) to finance the rural development project activities of Danfa, a village of about 835 people in Ghana. In this community the women are hard working but doubly disadvantaged. Along with a high illiteracy rate, the women are limited by inadequate income due to underemployment, under productivity, unfavorable farming conditions, and a lack of resources. Large families, frequent pregnancies, poor mother and child health, and high infant mortality all make matters worse for both the rural farm wife and her family. The project began with a nucleus of women that soon grew to between 24-30. Members soon formed small groups according to their occupational interests. The women grasped the self-help idea immediately. Once or twice a month there were demonstrations and the group worked together in such activities as making soap and pomade, preparing meals, and sewing. Meetings generally ended with a general group brainstorming and then members gathered in smaller groups to review their activities and plan for the future. During the 1st year of the project the men in the group rarely attended meetings. The group gave priority attention to their community's urgent need for working capital. 15 women farmers who met the criteria determined by the group received loans in the 1st round; only 8 satisfied the criteria in the 2nd round. At the beginning of the small loans scheme, the group decided to seek bigger loans from the bank if members proved credit worthy. This requirement was satisfied, and the group began negotiations for a loan with the Agricultural Development Bank. The group received the total group loan. The Ghana Home Science Association considers the project to be successful in several respects. Team spirit has developed the group, and the women play important and respected roles. Family planning problems are regularly presented for discussion, but it is difficult to correlate these ideas with practice. The ability of members to discuss these problems comfortably is an indication of their acceptance of family planning as an important topic in their lives.

The aim of this article is to describe the potential with respect to volunteer work among 55 to 70-year-old persons along with a two-dimensional typology (actual volunteer work and intention of volunteering or expanding actual volunteer work) and to identify the influencing factors. Based on the dataset from the transitions and old age potential (TOP) study, a total of 4421 men and women born between 1942 and 1958 were included. A multinomial regression model showed the predictors for group affiliation along with an engagement-related typology (internal, utilized and external volunteer potential as well as definite non-volunteers). More than a half of the persons in the study sample could be classified as internal or external volunteer potential. Volunteers and potential volunteers revealed more similarities regarding resources and social factors than potential volunteers and definite non-volunteers. Potential volunteers were more active in other informal fields of activity (e.g. nursing or child care) than definite non-volunteers. With respect to volunteer work, definite non-volunteers showed various social disadvantages (in particular with respect to education and health) compared to (potential) volunteers. Other informal activities did not seem to be in major conflict with volunteer activities, e.g. nursing or child care, as long as they were carried out with moderate or low intensity.

To explore the separate and combined effects of work and family stress on menstrual disorders and fibrocystic changes in Chinese working women. Data were obtained from a cross-sectional study of 1,642 female railway workers. The Effort-Reward Imbalance Questionnaire and Family Stress Scale were used to measure work stress and family stress, respectively; the menstrual and breast conditions were evaluated by gynecologic interview and a medical examination. Multivariate log-binomial regression was performed to analyze the associations. Menstrual disorders were found in 59.3% of female workers, and 54.8% had fibrocystic changes. The risk of menstrual disorders was significantly elevated with respect to work and family stress. The highest risk was found in the group with combined exposure to both work and family stress (RR with 95% CI 1.33 (1.18-1.49)). No significant association between stress and fibrocystic changes was observed. Menstrual disorders were associated with stress from work and family life, but not fibrocystic changes, in working women. Tailored intervention measures reducing the burden of stressful psychosocial work and family environment are needed to improve women's reproductive well-being.

The Product Quality Research Institute (PQRI) is a non-profit consortium of organizations working together to generate and share timely, relevant, and impactful information that advances drug product quality and development. The collaborative activities of PQRI participants have, in the case of orally inhaled and nasal drug products (OINDPs), resulted in comprehensive and widely-accepted recommendations for leachables assessments to help ensure patient safety with respect to this class of packaged drug products. These recommendations, which include scientifically justified safety thresholds for leachables, represent a significant milestone towards establishing standardized approaches for safety qualification of leachables in OINDP. To build on the success of the OINDP effort, PQRI's Parenteral and Ophthalmic Drug Products (PODP) Leachables and Extractables Working Group was formed to extrapolate the OINDP threshold concepts and best practice recommendations to other dosage forms with high concern for interaction with packaging/delivery systems. This article considers the general aspects of leachables and their safety assessment, introduces the PODP Work Plan and initial study Protocol, discusses the laboratory studies being conducted by the PODP Chemistry Team, outlines the strategy being developed by the PODP Toxicology Team for the safety qualification of PODP leachables, and considers the issues associated with application of the safety thresholds, particularly with respect to large-volume parenterals. Lastly, the unique leachables issues associated with biologics are described. The Product Quality Research Institute (PQRI) is a non-profit consortium involving industry organizations, academia, and regulatory agencies that together provide recommendations in support of regulatory guidance to advance drug product quality. The collaborative activities of the PQRI Orally Inhaled and Nasal Drug Products Leachables and Extractables Working Group resulted in a systematic and science-based approach to identify and qualify leachables, including the concept of safety thresholds. Concepts from this widely accepted approach, formally publicized in 2006, are being extrapolated to parenteral and ophthalmic drug products. This article provides an overview of extractables and leachables in drug products and biologics and discusses the PQRI Work Plan and Protocols developed by the PQRI Parenteral and Ophthalmic Drug Products Leachables and Extractables Working Group.

Previously we have conducted a randomised controlled trial (RCT) to evaluate the effect of a brief cognitive behavioural program with a vocational approach aiming to return disability pensioners with back pain to work, as compared to no intervention. One year after the intervention, 10 participants (22%) who received the program and 5 (11%) in the control group reported to have entered a return to work process. The aims of this study were to evaluate long-term effects of the intervention, and compare this effect to 2 reference populations not participating in the original trial. Three groups of disability pensioners were investigated: 1) Disability pensioners having back pain (n = 89) previously participating in the RCT (randomized to either a brief cognitive behavioural intervention or to a control group), 2) 342 disability pensioners having back pain, but refusing to participate in the study and 3) 449 disability pensioners having other musculoskeletal disorders than back pain. Primary outcome was return to work, defined as a reduction in payment of disability pension. Only 2 of 89 (2.3%) participants from the RCT had reduced disability pension at 3-years follow-up, both from the control group. None of the participants that had been in a process of returning to work after 1 year had actually gained employment at 3-years follow-up. In the 2 groups not participating in the previous RCT, only 4 (1.2%) and 8 (1.6%) had returned to work after 3 years respectively. The number of pensioners who returned to work was negligible in all groups regardless of having participated in a cognitive behavioural intervention or not.

This year, the World Health Organization focuses on restoring dignity and respect to health care workers. The aim of this study was to investigate the workplace stressors in physicians. The present study was performed in the period 2002 - 2004, among physicians treated in the Health Center Novi Sad. The examinees were asked to fill out a questionnaire--a workplace survey--to identify workplace stressors by using a self-evaluation method The physicians were divided into three groups: those practicing surgery (S), internal medicine (IM) and preventive-diagnostics (PD). Statistical analysis was done using SPSS and STATISTICA software. The sample included 208 physicians with an average age of 40 years (SD = 7,1); average work experience of 22 years (SD = 8,1). 65 physicians from group S and 108 physicians from group IM, identified the following workplace stressors: treating patients in life-threatening situations (47.7%, 30.6%, respectfully); on-call duty (13.8%, 12%); low salary (10.8%, 10.2%); limited diagnostic and therapeutic resources in the IM group. 35 physicians from the DP group identified the following stressors: low salary (25%), treating patients in life-threatening situations and a great number of patients (16%). The analysis of all examined physicians revealed the following workplace stressors: treating patients in life-threatening situations (34.6%), low salary (13%), on-call duty and overtime, and too many patients per physician (11.5%). Restoring the reputation of health workers can be done by providing new equipment to resolve life-threatening situations, by increasing salaries, reducing on-call time, as well as the number of patients. Generally speaking, this should help to improve the quality of work in the health care system, in accordance with the recommendations of the WHO.

Resistance exercise training commonly is performed against a constant external load (isotonic) or at a constant velocity (isokinetic). Researchers comparing the effectiveness of isotonic and isokinetic resistance-training protocols need to equalize the mechanical stimulus (work and velocity) applied. To examine whether the standardization protocol could be adjusted and applied to an eccentric training program. Controlled laboratory study. Controlled research laboratory. Twenty-one sport science male students (age = 20.6 ± 1.5 years, height = 178.0 ± 4.0 cm, mass = 74.5 ± 9.1 kg). Participants performed 9 weeks of isotonic (n = 11) or isokinetic (n = 10) eccentric training of knee extensors that was designed so they would perform the same amount of angular work at the same mean angular velocity. Angular work and angular velocity. The isotonic and isokinetic groups performed the same total amount of work (-185.2 ± 6.5 kJ and -184.4 ± 8.6 kJ, respectively) at the same angular velocity (21 ± 1°/s and 22°/s, respectively) with the same number of repetitions (8.0 and 8.0, respectively). Bland-Altman analysis showed that work (bias = 2.4%) and angular velocity (bias = 0.2%) were equalized over 9 weeks between the modes of training. The procedure developed allows angular work and velocity to be standardized over 9 weeks of isotonic and isokinetic eccentric training of the knee extensors. This method could be useful in future studies in which researchers compare neuromuscular adaptations induced by each type of training mode with respect to rehabilitating patients after musculoskeletal injury.

Verbal instruction for correcting errors versus such instructions plus videotape replay on learning the overhand throw.

2001-06-01

The influence of two methods of providing information to women, ages 19 to 22 years who were novices and learning the overhand throw with the nondominant arm, was examined. One group received verbal information on correcting errors, and a second group received the same information immediately prior to viewing a videotaped replay of a just completed throw. Performance was assessed quantitatively with respect to outcome (distance thrown) and qualitatively with respect to throwing form as measured on a 7-point rating scale by judges with a working knowledge of the overhand throw and with respect to throwing mechanics rated by a panel of experts in biomechanics using a scale of Leme and Shambes. Although the treatments led to better learning and performance, there was no significant difference between groups for distance thrown on the Leme and Shambes scale in Sessions 1-6 of 10 trials each on Session 7. The mean rating also indicated increased scores for both groups and better retention at posttest by the group receiving only verbal corrections. These results suggest that information provided by adding videotaped replay may be redundant and unnecessary for those in Sessions 1-6.

The capacity to work productively is a key component of health and emotional well-being. People who work in health care can be exposed to the fatigue of care. Compassion fatigue has been described as an occupational hazard specific to clinical work related severe emotional distress. In our study, we have evaluated compassion fatigue in a mental health group (47 psychiatric staff) and its relationship with inpatients (237 inpatients) affected by some psychiatric disorders. At baseline, the more significant data indicate a high percentage of Job Burnout and Compassion Fatigue in psychiatric nurses (respectively, 39.28%, 28.57%). Significant Compassion Fatigue percentage is present also in psychologist group (36.36%). Finally, in psychiatrists, the exposure to patients increased vicarious trauma (28.57%), but not job burnout. After a year of participation in Balint Groups, the psychiatric staff presented an overall reduction in total mean score in any administered scale (CBI: p<0.0000045; sCFs: (Vicarious Trauma: p<0.0288; Job Burnout: p<0.000001)). Thus, compassion fatigue causes concern among mental health professionals, and Balint Groups may represent a therapeutic strategy to help health professionals to face difficulties in challenging work environments.

Research has suggested a significant burden for patients with asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS). However, few studies have studied this population in the People's Republic of China, a region in the midst of rapid epidemiological change with respect to respiratory disease. The aim of this study was to assess the prevalence of ACOS and its association with patient outcomes in urban China. Data from the 2010, 2012, and 2013 China National Health and Wellness Survey, an Internet-based survey of adults in urban China, were used (N=59,935). Respondents were categorized into one of four groups based on self-reported physician diagnoses: ACOS, asthma only, COPD only, or control (ie, no asthma or COPD). A propensity score matching procedure was conducted to cull the control group into a subgroup (ie, matched controls) who resembled patients with ACOS, asthma only, and COPD only. These four groups (ACOS, asthma only, COPD only, matched controls) were then compared with respect to health status (Short Form-12 version 2/Short Form-36 version 2), work productivity, and health care resource use using generalized linear models. Patients with ACOS (N=366) comprised 0.61% of the adult population, 30.73% of the asthma population, and 18.60% of the COPD population in the People's Republic of China. Patients with ACOS reported significantly worse health status (eg, health utilities =0.63, 0.66, 0.63, and 0.69 for ACOS, COPD only, asthma only, and matched controls, respectively) and significantly greater work impairment (eg, overall work impairment =43.65%, 35.19%, 48.55%, and 29.80%, respectively) and health care resource use (eg, physician visits in the past 6 months =5.13, 3.84, 4.65, and 2.39, respectively) compared with matched controls and patients with COPD only. Few significant differences were observed between patients with ACOS and asthma only. Patients with ACOS have a greater comorbidity burden and significantly worse health outcomes compared with COPD only patients and matched controls. Better management of these patients may help to improve their outcomes.

The use of dental computer-aided design/computer-aided manufacturing (CAD/CAM) restoration is rapidly increasing. This study was performed to evaluate the marginal and internal cement thickness and the adhesive gap of internal cavities comprising CAD/CAM materials using two digital impression acquisition methods and micro-computed tomography. Images obtained by a single-image acquisition system (Bluecam Ver. 4.0) and a full-color video acquisition system (Omnicam Ver. 4.2) were divided into the BL and OM groups, respectively. Silicone impressions were prepared from an ISO-standard metal mold, and CEREC Stone BC and New Fuji Rock IMP were used to create working models (n=20) in the BL and OM groups (n=10 per group), respectively. Individual inlays were designed in a conventional manner using designated software, and all restorations were prepared using CEREC inLab MC XL. These were assembled with the corresponding working models used for measurement, and the level of fit was examined by three-dimensional analysis based on micro-computed tomography. Significant differences in the marginal and internal cement thickness and adhesive gap spacing were found between the OM and BL groups. The full-color movie capture system appears to be a more optimal restoration system than the single-image capture system.

To evaluate the mechanical properties and microstructure of laser-welded joints with different welding wires for clinical use of welding wire. The standard tensile test and three-point bending test rods were made from Co-Cr and Ni-Cr alloy, and were laser-welded with different welding wire (commercially welding wire and casting wire). Then the tensile rods were tested for the ultimate tensile strength (UTS), and the bending rods for the ultimate bending strength (UBS). The results was analyzed by one-way ANOVA. The tensile fracture surface were examined by scanning electron microscopy (SEM). Metallurgical analysis were also performed on polished longitudinal sectioned samples. For Co-Cr alloy, the UTS of casting wire group and commercially welding wire group was respectively (606.40+/-82.53)MPa and (693.61+/-47.68)MPa; the UBS was respectively (997.95+/-88.89)MPa and (1160.76+/-91.59)MPa. ANOVA showed a significant difference of UTS and UBS between the two groups at the 0.05 level (P<0.05). For Ni-Cr alloy, the UTS of casting wire group and commercially welding wire group was respectively (558.14+/-46.75)MPa and (582.32+/-35.43)MPa; the UBS was respectively (1084.75+/-46.02)MPa and (1078.29+/-36.25)MPa. There was no significant difference between the two groups (P>0.05). SEM and metallurgical examination showed the welded zone exhibiting more cracks in the casting wire group than in the commercially welding wire group. It would be advisable to work with commercially welding wire for the joints that need better strength.

To investigate the working patterns and patient base of registered clinical dental technicians (CDTs); their relationships with dentists and other professionals in the dental team; their willingness to work within the NHS and their expectations for the future as a new professional group. Face-to-face qualitative interviews of registered CDTs, selected because of their geographic representation and mode of working, informed the development of a postal questionnaire survey of all early registrants with the General Dental Council (GDC). The majority of CDTs reported working part-time, often combining clinical practice with their role as a dental technician. They reported both positive and negative working relationships with dentists and dental technicians, demonstrating collaboration and/or competition depending on whether the scope of CDTs was respected and patient care was shared or lost. CDTs role in the NHS was limited because they did not have the status of becoming a recognised provider of dental care. There was a desire to expand their scope of practice in future. CDTs are embracing their new status as an occupational group within dentistry. Core features of becoming a professional group were exhibited including the importance of social and financial status and the need to negotiate their current and future roles in the healthcare system.

A persistent problem in hernia surgery concerns the repair of bilateral inguinal hernias. A retrospective analysis of 78 patients with bilateral inguinal hernias was performed. Hernia repair was performed either by an open anterior access (modified Shouldice repair) or a laparoscopic posterior approach (TAPP repair). The two patient groups were similar with regard to ASA classification, age, and sex. The intraoperative complication rate was low (2.6% to 7.8%), whereas postoperative complications occurred more frequently (7.7% to 15.4%). The recurrence rate was low in both groups: 5.1% for the open group and 1.3% for the laparoscopic group. The mean hospital stay was 4 days for both groups, and the mean off-work times were 56.4 days and 17.9 days for the open and laparoscopic group, respectively (p < 0.05). Both procedures gave satisfactory results. The main advantages of the laparoscopic approach are the shorter convalescence time and quicker return to work.

Exploring the Complexities of Group Work in Science Class: a Cautionary tale of Voice and Equitable Access to Resources for Learning

NASA Astrophysics Data System (ADS)

Richmond, Gail

The interactions of 2 focus students with others in their cooperative base groups were examined as the students designed, carried out, and interpreted scientific investigations. These 2 students differed with respect to race, gender, socioeconomic status, and academic achievement. They were alike in that both maintained high levels of motivation and interaction with the scientific problems they faced. Their group interactions were not entirely positive, and the difficulties and inequities they faced are described. The data make manifest that group work is a complex process; educators must be sensitive and responsive to the subtle ways understanding can be enhanced or undermined as a result of group dynamics, which are in turn determined by individual expectations - often unfounded - of others' capacities and behaviors, and perceptions of desired group and individual outcomes. These observations also have implications for how educators help prepare prospective teachers to develop effective pedagogical strategies for teaching diverse students.

To determine the relationship between shift work and mental health, particularly insomnia, depression, and suicidal ideation, among electronics production workers. A survey was conducted with 14,226 workers from an electronics manufacturer in South Korea. After excluding 112 individuals with incomplete responses, 14,114 respondents were analyzed. As part of a larger project, we collected data on respondents' general characteristics, work-related characteristics, and health status; however, in this study, we focused on the data related to shift work and mental health. Insomnia, depression, and suicidal ideation were set as dependent variables and working schedule as set as the independent variable. We performed multiple logistic regression analysis with daytime workers as the reference group. The model was adjusted for age, gender, body mass index, workplace, educational level, and marital status with or without children under 6 years of age. Relative to daytime workers, shift workers had 2.35, 1.23, and 1.17 greater odds of insomnia, depression, and suicidal ideation, respectively. Within the shift worker group, we found that the odds of depression and suicidal ideation increased dramatically when respondents had insomnia. The ORs for depression and suicidal ideation were 4.899 and 7.934, respectively. Our findings suggest that shift work is related to an increased risk of mental health problems in production workers, and the sleep disturbance related with shift work is a central mechanism for this relationship. Since these results suggest that proactive management of sleep problems might attenuate their detrimental effects on shift worker's mental health.

To evaluate the application of hand-use ProTaper instruments in endodontic treatment of molar canals. A total of 203 permanent molars were randomly divided into the experimental group (99 molars) and control group (104 molars) prepared by hand-use ProTaper instruments and standard stainless steel K-file, respectively. The molars in the two groups were obturated by cold lateral condensation technique. The root canal preparation and obturation were evaluated by radiograph, and the working time of preparation and post-operative emergencies were analyzed. The preparation time in the experimental group was obviously shorter than that in the control group (P<0.01). The rate of satisfactory effect was significantly higher in the experimental group than in the control group (P<0.01), and the rate of post-operative emergencies was significantly lower in the experimental group (P<0.01). The application of hand-use ProTaper instruments may improve the effect of root canal treatment of the molars and shorten the working time and reduce the post-operative emergencies.

Evidence suggests that HT1001™, a proprietary North American ginseng extract containing known levels of active ginsenosides, may improve cognitive function. Importantly, individuals with schizophrenia show marked deficits in working memory, which are believed to be predictive of functional outcome in this population. The present study aimed to characterize the effect of HT1001 on working memory in a group of stable individuals with schizophrenia. In a double-blind, placebo-controlled study design, a total of 64 individuals satisfying DSM-IV criteria for schizophrenia were randomly assigned to receive either HT100 or placebo for 4 weeks. Verbal working memory and visual working memory were assessed at baseline and again at the end of the treatment phase using the Letter-Number Span Test and Visual Pattern Test, respectively. Symptoms and medication side effects were also measured at baseline and post-treatment. Visual working memory was significantly improved in the HT1001 group, but not in the placebo group. Furthermore, extrapyramidal symptoms were significantly reduced after 4 weeks treatment with HT1001, whereas no difference in extrapyramidal effects was observed in the placebo group. These results provide a solid foundation for the further investigation of HT1001 as an adjunct therapy in schizophrenia, as an improvement in working memory and a reduction in medication-related side effects has considerable potential to improve functional outcome in this population.

Health risk appraisals (HRA) are a common type of workplace health promotion programme offered by American employers. In the United Kingdom, evidence of their effectiveness for promoting health behaviour change remains inconclusive. This randomized controlled trial examined the effects of two HRA interventions on lifestyle parameters, mental health and work ability in a UK context. A total of 180 employees were randomized into one of three groups: Group A (HRA augmented with health promotion and education activities), Group B (HRA only) and Group C (control, no intervention). After 12 months, changes in mean scoring in 10 lifestyle, mental health and work ability indices were compared, Groups A and B demonstrated non-significant improvements in 70% and 80%, respectively, compared with controls (40%). Odds ratios revealed that, compared with the control group, Group A was 29.2 (95% CI: 9.22-92.27) times more likely to report a perceived change in lifestyle behaviour; Group B 4.4 times (95% CI: 1.65-11.44). In conclusion, participation in the HRA was associated with a higher likelihood of perceived lifestyle behaviour change which was further increased in the augmented HRA group, thereby providing preliminary evidence that HRA and augmented HRA in particular may help UK employees make positive healthy lifestyle changes.

This observational study aimed to determine how 1-year changes in work time control (WTC) have an impact upon objectively measured fatigue and sleep among employees. Thirty-nine employees were divided into two groups according to whether or not their WTC increased from baseline to 1 year later. Psychomotor vigilance task (PVT) and wrist actigraphy were used to objectively measure fatigue and sleep, respectively. Self-reported outcomes were also measured. The increased WTC group showed gradual improvements in PVT performance and sleep quality over the course of the follow-up period compared with the not-increased WTC group. Between-group differences were statistically significant for PVT lapses and tended to be significant for PVT speed after 1 year. A progressive increase in WTC could play a crucial role in reducing fatigue and promoting sleep among employees.

The Royal College of Physicians and Surgeons of Canada specifies both respect for diversity as a requirement of professionalism and culturally sensitive provision of medical care. The purpose of the present study was to evaluate the perception of preparedness and attitudes of medical residents to deliver cross-cultural care. The Cross Cultural Care Survey was sent via e-mail to all Faculty of Medicine residents (approx. 450) in an academic health sciences centre. Comparisons were made between psychiatry residents, family medicine residents, and other residency groups with respect to training, preparedness, and skillfulness in delivering cross-cultural care. Seventy-three (16%) residents responded to the survey. Residents in psychiatry and family medicine reported significantly more training and formal evaluation regarding cross-cultural care than residents in other programs. However, there were no significant differences in self-reported preparedness and skillfulness. Residents in family medicine were more likely to report needing more practical experience working with diverse groups. Psychiatry residents were less likely to report inadequate cross-cultural training. While most residents reported feeling skillful and prepared to work with culturally diverse groups, they report receiving little additional instruction or formal evaluation on this topic, particularly in programs other than psychiatry and family medicine.

The purpose of this research is to establish the ability of employees by work ability index (WAI), physical work capacity (PWC), and finding the correlation between them. Establishing the PWC index with attention to WAI values for the purpose of saving in costs and time of PWC measurements is another aim of this project. The present research is an analytic cross-sectional and one-trail study. The study population consists of 228 randomly selected registered nurses from hospitals in Isfahan (Iran). The WAI and PWC were established through WAI questionnaire and Fax equation and by using ergometer bicycle, respectively. The resulting data were analyzed using SPSS 16 software. Average WAI and PWC among the study population were 38.25±4.4 and 4.45±0.7, respectively. Pearson test results showed no significant correlation between PWC and WAI in different age groups (r=0.3 and P>0.05). Multiple linear regression analysis showed that the variables of age and diagnosed diseases were the most effective factors of WAI (β=0.18 and P>0.05). Pearson test revealed a significant correlation between the number of diagnosed diseases and PWC index in age groups of 40-49 years. Average WAI in this research, like other studies on similar jobs is in the acceptable level of >36. Work ability index and PWC index in different age groups did not show a significant correlation and this suggests that there are essential discrepancies in work ability evaluations made by each index and it is not possible to predict PWC index using WAI values. Given the PWC results and the level of nursing staff's activity (low, medium) the WAI is a suitable instrument to establish the professionals' abilities. This study revealed that 27.6% of individuals were subject to medium-low work ability risk (WAI<37), which was 1.8 times that of Finland's professional health Institute, which could be caused by shift working and increased working hours.

Mental work may promote caloric intake, whereas exercise may offset positive energy balance by decreasing energy intake and increasing energy expenditure. This study aimed to replicate previous findings that mental work increases caloric intake compared with a rest condition and assess whether exercise after mental work can offset this effect. Thirty-eight male and female university students were randomly assigned to mental work + rest (MW + R) or mental work + exercise (MW + E). Participants also completed a baseline rest (BR) visit consisting of no mental work or exercise. Visit order was counterbalanced. During the MW + R or MW + E visit, participants completed a 20-min mental task and either a 15-min rest (MW + R) or a 15-min interval exercise (MW + E). Each visit ended with an ad libitum pizza lunch. A two-way repeated-measures ANOVA was used to compare eating behavior between groups. Participants in the MW + R condition consumed an average of 100 more kilocalories compared with BR (633.3 ± 72.9 and 533.9 ± 67.7, respectively, P = 0.02), and participants in MW + E consumed an average of 25 kcal less compared with BR (432.3 ± 69.2 and 456.5 ± 64.2, respectively, P > 0.05). When including the estimated energy expenditure of exercise in the MW + E conditions, participants were in negative energy balance by an average of 98.5 ± 41.5 kcal, resulting in a significant difference in energy balance between the two groups (P = 0.001). An acute bout of interval exercise after mental work resulted in significantly decreased food consumption compared with a nonexercise condition. These results suggest that an acute bout of exercise may be used to offset positive energy balance induced by mental tasks.

Major mental disorders are highly disabling conditions that result in substantial socioeconomic burden. Subjective and objective measures of functioning or ability to work, their concordance, or risk factors for them may differ between disorders. Self-reported level of functioning, perceived work ability, and current work status were evaluated among psychiatric care patients with schizophrenia or schizoaffective disorder (SSA, n=113), bipolar disorder (BD, n=99), or depressive disorder (DD, n=188) within the Helsinki University Psychiatric Consortium Study. Correlates of functional impairment, subjective work disability, and occupational status were investigated using regression analysis. DD patients reported the highest and SSA patients the lowest perceived functional impairment. Depressive symptoms in all diagnostic groups and anxiety in SSA and BD groups were significantly associated with disability. Only 5.3% of SSA patients versus 29.3% or 33.0% of BD or DD patients, respectively, were currently working. About half of all patients reported subjective work disability. Objective work status and perceived disability correlated strongly among BD and DD patients, but not among SSA patients. Work status was associated with number of hospitalizations, and perceived work disability with current depressive symptoms. Psychiatric care patients commonly end up outside the labour force. However, while among patients with mood disorders objective and subjective indicators of ability to work are largely concordant, among those with schizophrenia or schizoaffective disorder they are commonly contradictory. Among all groups, perceived functional impairment and work disability are coloured by current depressive symptoms, but objective work status reflects illness course, particularly preceding psychiatric hospitalizations.

Kaposi's sarcoma herpesvirus (KSHV) is linked causally to Kaposi's sarcoma. Epidemiological studies have shown that KSHV transmission can occur during sex among homosexual men, but heterosexual transmission seems to be very rare in KSHV low prevalence countries. A seroepidemiological study was conducted to determine whether KSHV is transmitted sexually between heterosexuals in an endemic country. Sera from 282 subjects of African origin living in Djibouti were tested for antibodies to KSHV and HIV-1. Among the 282 individuals, 43 were female prostitutes working in the streets (group 1), 123 were female prostitutes working in luxury bars (group 2), 41 were non-prostitute females (group 3), and 75 were non-prostitute males (group 4). KSHV seroprevalence was 26, 20, 17, and 36% in groups 1, 2, 3, and 4, respectively. The seroprevalence of KSHV is not different between street or bar prostitutes and non-prostitute females (OR = 1.67; P = 0.34 and OR = 1.18; P = 0.73). These results suggest that in this endemic country commercial sex work does not seem to be a risk factor for KSHV infection and provides evidence against heterosexual transmission of KSHV in the female population studied.

Currently, chronic fatigue syndrome (CFS) seriously affects people's normal living and work. In the present paper, the physiological parameters, such as tissue oxygenation saturation and heart rate, were used to evaluate the subjects' fatigue degree, and the fatigue resistance capsule and coffee were taken as a measure to adjust the fatigue. Human tissue oxygen saturation (rSO2) can be monitored noninvasively and in real time by near infrared spectroscopy (NIRS) based on spatially-resolved spectroscopy. Aiming at those brainworkers who need to work in an office for a long time; two static experiments were designed to evaluate the fatigue degree of the subjects who either take the fatigue resistance capsules/coffee or not. The rSO2 and heart rate (HR) of the subjects in the experiment group and contrast group were measured respectively for fatigue evaluation. This work particularly analyzed the changes in rSO2 in these two groups. The results show that the rSO2 of subjects in the experiment group evidently increased compared to that in the contrast group when the subjects took the fatigue resistance capsule or coffee, thereby show that the health food can reduce the fatigue to a certain extent.

Preventing a Leak: Two Perspectives on Creating Supportive Environment for Graduate Student Colleagues

NASA Astrophysics Data System (ADS)

Wohl, Ellen; Lininger, Katherine

2017-04-01

Debate continues about whether there exists a leaky pipeline for women in STEM fields within academia, as well as the causes of leaks - points in an individual's career where women are more likely than men to choose a non-academic pathway. Statistics on MS and PhD degrees awarded in STEM fields indicate that one of these leaks occurs during and immediately following graduate school. Here, we present two perspectives, that of a full professor and a graduate student, on how to create an environment in which geosciences graduate students can thrive psychologically and professionally. We recognize the challenges faced by many underrepresented groups, but here we focus specifically on gender diversity from the perspective of white women. From the perspective of a faculty advisor overseeing a research group, the goal is to treat each member of the group as an individual and to develop a mentoring relationship that most effectively fosters that individual's development as a scientist, while maintaining a cohesive, collegial group dynamic. Among the recommended ways to achieve this are: maintaining flexibility in the work schedule, with success evaluated by outcomes; consideration of work-life balance; respect for diverse approaches to problem solving; recognition that individuals can be most productive, satisfied, and engaged when their individual contributions are acknowledged and valued; and respect for different choices for a career path and for changes in those choices during graduate studies. From the perspective of a graduate student, it is important that an advisor demonstrates a clear commitment to treating each member of a research group as a valued individual with differing needs. In addition to the recommendations above for achieving a positive and supportive research group, as a graduate student it is useful to have multiple mentors and role models who have had different career tracks and can provide diverse perspectives and advice. Graduate students can also take it upon themselves to enhance retention of underrepresented groups in STEM through forming local support and networking groups or advocating for better institutional policies (e.g., paid parental leave policies for graduate students). Supporting and encouraging graduate students who undertake activities aimed at increasing diversity in STEM is another way that advisors can create a better working environment for their graduate students. Success for women in STEM fields and their retention over the long term can depend upon the experiences they have in graduate school and whether they believe it is possible to create a career path that works for their individual needs and work-life balance.

Abstract Background: Given the persistent disparity in the advancement of women compared with men faculty in academic medicine, it is critical to develop effective interventions to enhance women's careers. We carried out a cluster-randomized, multifaceted intervention to improve the success of women assistant professors at a research-intensive medical school. Materials and Methods: Twenty-seven departments/divisions were randomly assigned to intervention or control groups. The three-tiered intervention included components that were aimed at (1) the professional development of women assistant professors, (2) changes at the department/division level through faculty-led task forces, and (3) engagement of institutional leaders. Generalized linear models were used to test associations between assignment and outcomes, adjusting for correlations induced by the clustered design. Results: Academic productivity and work self-efficacy improved significantly over the 3-year trial in both intervention and control groups, but the improvements did not differ between the groups. Average hours worked per week declined significantly more for faculty in the intervention group as compared with the control group (−3.82 vs. −1.39 hours, respectively, p = 0.006). The PhD faculty in the intervention group published significantly more than PhD controls; however, no differences were observed between MDs in the intervention group and MDs in the control group. Conclusions: Significant improvements in academic productivity and work self-efficacy occurred in both intervention and control groups, potentially due to school-wide intervention effects. A greater decline in work hours in the intervention group despite similar increases in academic productivity may reflect learning to “work smarter” or reveal efficiencies brought about as a result of the multifaceted intervention. The intervention appeared to benefit the academic productivity of faculty with PhDs, but not MDs, suggesting that interventions should be more intense or tailored to specific faculty groups.

Our aim was to investigate how circadian adaptation to night shift work affects psychomotor performance, sleep, subjective alertness and mood, melatonin levels, and heart rate variability (HRV). Fifteen healthy police officers on patrol working rotating shifts participated to a bright light intervention study with 2 participants studied under two conditions. The participants entered the laboratory for 48 h before and after a series of 7 consecutive night shifts in the field. The nighttime and daytime sleep periods were scheduled during the first and second laboratory visit, respectively. The subjects were considered “adapted” to night shifts if their peak salivary melatonin occurred during their daytime sleep period during the second visit. The sleep duration and quality were comparable between laboratory visits in the adapted group, whereas they were reduced during visit 2 in the non-adapted group. Reaction speed was higher at the end of the waking period during the second laboratory visit in the adapted compared to the non-adapted group. Sleep onset latency (SOL) and subjective mood levels were significantly reduced and the LF∶HF ratio during daytime sleep was significantly increased in the non-adapted group compared to the adapted group. Circadian adaptation to night shift work led to better performance, alertness and mood levels, longer daytime sleep, and lower sympathetic dominance during daytime sleep. These results suggest that the degree of circadian adaptation to night shift work is associated to different health indices. Longitudinal studies are required to investigate long-term clinical implications of circadian misalignment to atypical work schedules. PMID:23923024

[Significance of sex and gender studies for anthropology].

PubMed

Kirchengast, Sylvia

2004-09-01

The formation of a special working group for gender studies within the German Anthropological Society (GfA) makes necessary a description of history as well as topics of gender studies within science and biological anthropology. In German speaking countries, gender studies are predominantly associated with social and cultural sciences, although very successful working groups belonging to natural sciences already exist. Unfortunately, up to now gender studies within natural sciences are often interpreted negatively and the existence of sex is denied. This may be due to the long and difficult history of gender studies in natural sciences. For a long time, pseudoscientific misinterpretations of results of gender studies were used to manifest the inferior social position of women. However, since more than thirty years respectable gender studies are integrated in social as well as natural sciences. Gender studies are integrative parts of nearly all subdisciplines of biological anthropology. The formation of a working group for gender studies within the GfA seems therefore to be useful.

On the International Agency for Research on Cancer classification of glyphosate as a probable human carcinogen.

Tarone, Robert E

2018-01-01

The recent classification by International Agency for Research on Cancer (IARC) of the herbicide glyphosate as a probable human carcinogen has generated considerable discussion. The classification is at variance with evaluations of the carcinogenic potential of glyphosate by several national and international regulatory bodies. The basis for the IARC classification is examined under the assumptions that the IARC criteria are reasonable and that the body of scientific studies determined by IARC staff to be relevant to the evaluation of glyphosate by the Monograph Working Group is sufficiently complete. It is shown that the classification of glyphosate as a probable human carcinogen was the result of a flawed and incomplete summary of the experimental evidence evaluated by the Working Group. Rational and effective cancer prevention activities depend on scientifically sound and unbiased assessments of the carcinogenic potential of suspected agents. Implications of the erroneous classification of glyphosate with respect to the IARC Monograph Working Group deliberative process are discussed.

This 40-week workplace physical training RCT investigated the effect of soccer and Zumba, respectively, on muscle pain intensity and duration, work ability, and rating of perceived exertion (RPE) during work among female hospital employees. 107 hospital employees were cluster-randomized into two training groups, and a control group. The training was conducted outside working hours as two-three 1-h sessions per week for the first 12 weeks, and continued as one-two 1-h sessions per week for the last 28 weeks. Muscle pain intensity and duration, work ability, and RPE during work were measured at baseline and after 12 and 40 weeks. After 12 weeks, both the soccer (-1.9, 95% CI, -3.0, -0.8, P = 0.001) and the Zumba group (-1.3, 95% CI, -2.3, -0.3, P = 0.01) reduced the pain intensity (on a scale from 0 to 10) in the neck-shoulder region (eta squared = 0.109), whereas only the soccer group (-1.9, 95% CI, -3.2, -0.7, P = 0.002, eta squared = 0.092) showed a reduction after 40 weeks referencing the control group. After 40 weeks, both the soccer (-16.4 days, 95% CI, -29.6, -3.2, P<0.02) and the Zumba group (-16.6 days, 95% CI, -28.9, -4.2, P<0.01) reduced the pain duration during the past 3 months in the neck-shoulder region (eta squared = 0.077). No significant effects on intensity or duration of pain in the lower back, RPE during work or work ability were found. The present study indicates that workplace initiated soccer and Zumba training improve neck-shoulder pain intensity as well as duration among female hospital employees.

Background Declining physical activity (PA) and associated health risk factors are well established. Workplace strategies to increase PA may be beneficial to ameliorate extensive sedentary behavior. This study assessed the effectiveness of two PA interventions in workplace settings. Methods Interventions were conducted over 40 days targeting insufficiently active (<150 min/wk PA) and/or obese (BMI ≥ 30 kg/m2) adults; participants were randomly allocated to instructor-led exercise sessions either after-work (n = 25) or in-work (n = 23) with a 60 minPA/day common goal, or a wait-listed control group (n = 23). The programme commenced with low-moderate physical activities and progressed to high intensity game style activities by week six. Adherence and compliance were determined using both objective measures of daily PA time from HR monitors and self-report responses to PA questionnaires. Cardiovascular and metabolic risk factors were measured pre- and post-intervention. Changes across the study were analysed using Chi square and repeat-measures ANOVA. Results Adherence rates (completed pre and post-testing) were not different between groups (76.0 vs 65.2%). Compliance for the instructor-led sessions was higher for the after-work group (70.4% vs 26.4%, respectively). Increased total PA and aerobic fitness, and decreased weight in both intervention groups were found relative to controls. The after-work group undertook more vigorous PA, and had greater weight loss and fasting blood glucose improvement, relative to in-work participants and controls. Conclusions These workplace interventions resulted in rapid and dramatic increases in PA behaviour and important health benefits. Short, in-work PA sessions were less efficacious than longer after-work sessions. PMID:29546212

Guilhem, Gaël; Cornu, Christophe; Guével, Arnaud

2012-01-01

Context: Resistance exercise training commonly is performed against a constant external load (isotonic) or at a constant velocity (isokinetic). Researchers comparing the effectiveness of isotonic and isokinetic resistance-training protocols need to equalize the mechanical stimulus (work and velocity) applied. Objective: To examine whether the standardization protocol could be adjusted and applied to an eccentric training program. Design: Controlled laboratory study. Setting: Controlled research laboratory. Patients or Other Participants: Twenty-one sport science male students (age = 20.6 ± 1.5 years, height = 178.0 ± 4.0 cm, mass = 74.5 ± 9.1 kg). Intervention(s): Participants performed 9 weeks of isotonic (n = 11) or isokinetic (n = 10) eccentric training of knee extensors that was designed so they would perform the same amount of angular work at the same mean angular velocity. Main Outcome Measure(s): Angular work and angular velocity. Results: The isotonic and isokinetic groups performed the same total amount of work (−185.2 ± 6.5 kJ and −184.4 ± 8.6 kJ, respectively) at the same angular velocity (21 ± 1°/s and 22°/s, respectively) with the same number of repetitions (8.0 and 8.0, respectively). Bland-Altman analysis showed that work (bias = 2.4%) and angular velocity (bias = 0.2%) were equalized over 9 weeks between the modes of training. Conclusions: The procedure developed allows angular work and velocity to be standardized over 9 weeks of isotonic and isokinetic eccentric training of the knee extensors. This method could be useful in future studies in which researchers compare neuromuscular adaptations induced by each type of training mode with respect to rehabilitating patients after musculoskeletal injury.

To investigate the effect of occupational toluene diisocyanate(TDI) exposure on matrix metalloproteinases-9 (MMP-9) and tissue inhibitor of metalloproteinase-1(TIMP-1), and analysis of the correlation of MMP-9,TIMP-1,MMP-9/TIMP-1 and lung function. In October 2014, based on cluster sampling, we conducted a cross-sectional study in a TDI production factory located in China's western region. 61 exposed workers were recruited from workers engaged in packing, operating and checking. Based on different levels of the external exposure, the packers were classified as high exposed group, while operators and checkers as low exposed group. 58 factory managers, matching age and agent, were selected as controls, having same work intense and not contacting the TDI or other allergens. The questionnaire surveys were used to obtain the agent, age, work age, smoking and drinking, personal and family allergic history, occupational history, and the recent health conditions. The levels of MMP-9 and TIMP-1 in serum of subjects were determind by ELISA. The time weighted average concentrations (8h-TWA) were used to describe the levels of TDI air exposure in working environment. Spearman correlation assay was used to investigate the correlation of MMP-9, TIMP-1, MMP-9/TIMP-1 and lung function, exposure time. 8-hour TWA means of TDI air levels in exposed group, packers, operators and checkers were 0.39, 0.76, 0.25 mg/m(3), respectively . According to the external exposure concentration, the packers were classified as high exposed group, and the operators and checkers were classified as low exposed group. In controls, low exposed group and high exposed group, the levels of MMP-9, respectively, were (807.21±347.70),(586.91±317.50),(388.94±312.01) ng/ml (χ(2)=16.69, P<0.001), respectively, and the P50(P25-P75) of MMP-9/TIMP-1 were 4.67(2.87-6.68), 2.3(1.44-3.48), 1.11(0.59-1.48) (χ(2)=39.42, P<0.001), respectively, and the concentrations of TIMP-1, were (173.44±72.67), (236.12±51.98), (302.81±44.39) ng/ml (F=20.09, P< 0.001), respectively. The levels P50(P25-P75) of FVC, FEV1.0 and FEV1.0/FVC in exposed group were, 92.8% (86.0%-101.8%), 85.5%(76.7%-92.8%), 112.5(108.2-118.5), respectively, which were lower than that in control group (124.3%(107.9%-144.2%), 142.7%(119.1%-155.7%), 129.2(123.5-134))(Z values were 7.70, 8.97, 8.62, and all P<0.001). Spearman rank correlation analysis showed that levels of MMP-9 were positively associated with FEV1.0, and FEV1.0/FVC (r values were 0.27, 0.25, respectively, all P<0.05), and The levels of TIMP-1 were negatively associated with FVC, FEV1.0, and FEV1.0/FVC (r valuse were -0.33, -0.39, -0.39, all P<0.05).The levels of MMP-9 were negatively correlated with exposure time(r=-0.26, P=0.040). The positive correlations of MMP-9/TIMP-1 with FVC, FEV1.0, and FEV1.0/FVC were also found (r valuse were 0.34, 0.44, 0.40, all P<0.05). TDI exposure could induce the downs of MMP-9 and MMP-9/TIMP-1 associated with lung functions. The MMP-9 and MMP-9/TIMP-1,in a way, could reflect the respiratory inflammatory injury caused by TDI exposure.

This study was designed to compare stapled vs. conventional hemorrhoidectomy for patients with acute thrombosed hemorrhoids. Forty-one patients with acute thrombosed hemorrhoids were randomized into: 1) stapled hemorrhoidectomy (PPH group; n = 21), and 2) open hemorrhoidectomy (open group; n = 20). Emergency surgery was performed with perioperative data and complications were recorded. Patients were followed up by independent assessors to evaluate pain, recurrence, continence function, and satisfaction at regular intervals. The median follow-up for the PPH group and open group were 59 and 56 weeks, respectively. There was no significant difference in terms of the hospital stay, complication rate, and continence function; however, the mean pain intensity in the first postoperative week was significantly less in the PPH group (4.1 vs. 5.7, P = 0.02). Patients in the PPH group recovered significantly faster in terms of the time to become analgesic-free (4 vs. 8.5 days, P < 0.01), time to become pain-free (9 vs. 20.5 days, P = 0.01), resumption of work (7 vs. 12.5 days, P = 0.01), and time for complete wound healing (2 vs. 4 weeks, P < 0.01). On long-term follow-up, significantly fewer patients in the PPH group complained of recurrent symptoms (0 vs. 5, P = 0.02). The overall symptom improvement and patients' satisfaction were significantly better in the PPH group (90 vs. 80 percent, P = 0.03 and +3 vs. +2, P < 0.01 respectively). Stapled hemorrhoidectomy is safe and effective for acute thrombosed hemorrhoids. Similar to elective stapled procedure, emergency stapled excision has greater short-term benefits compared with conventional excision: diminished pain, faster recovery, and earlier return to work. Long-term results and satisfaction were excellent.

Beyond pluralism: psychoanalysis and the workings of mind.

Subjects that Freud excluded or incompletely explored have been sites of theoretical expansion in over a century of observation: the role of the other, the self, the preoedipal period, action, the countertransference, limits to neutrality/anonymity/abstinence, the loci of the analytic drama, effects beyond interpretation, agency, and basic needs (versus wishes). These developments have led to conflicting theories and sect-like groupings within the field. Group psychological processes underlying this are discussed; and a broad and inclusive view of psychoanalysis is proposed under the heading of the study of the workings of mind. Additionally, substantial integrative proposals are offered with respect to the central tasks of individual development, theories of mind, the relational turn, and aspects of technique.

Improving construction site safety through leader-based verbal safety communication.

2010-10-01

The construction industry is one of the most injury-prone industries, in which production is usually prioritized over safety in daily on-site communication. Workers have an informal and oral culture of risk, in which safety is rarely openly expressed. This paper tests the effect of increasing leader-based on-site verbal safety communication on the level of safety and safety climate at construction sites. A pre-post intervention-control design with five construction work gangs is carried out. Foremen in two intervention groups are coached and given bi-weekly feedback about their daily verbal safety communications with their workers. Foremen-worker verbal safety exchanges (experience sampling method, n=1,693 interviews), construction site safety level (correct vs. incorrect, n=22,077 single observations), and safety climate (seven dimensions, n=105 questionnaires) are measured over a period of up to 42 weeks. Baseline measurements in the two intervention and three control groups reveal that foremen speak with their workers several times a day. Workers perceive safety as part of their verbal communication with their foremen in only 6-16% of exchanges, and the levels of safety at the sites range from 70-87% (correct observations). Measurements from baseline to follow-up in the two intervention groups reveal that safety communication between foremen and workers increases significantly in one of the groups (factor 7.1 increase), and a significant yet smaller increase is found when the two intervention groups are combined (factor 4.6). Significant increases in the level of safety are seen in both intervention groups (7% and 12% increases, respectively), particularly in regards to 'access ways' and 'railings and coverings' (39% and 84% increases, respectively). Increases in safety climate are seen in only one of the intervention groups with respect to their 'attention to safety.' No significant trend changes are seen in the three control groups on any of the three measures. Coaching construction site foremen to include safety in their daily verbal exchanges with workers has a significantly positive and lasting effect on the level of safety, which is a proximal estimate for work-related accidents. It is recommended that future studies include coaching and feedback at all organizational levels and for all involved parties in the construction process. Building client regulations could assign the task of coaching to the client appointed safety coordinators or a manager/supervisor, and studies should measure longitudinal effects of coaching by following foremen and their work gangs from site to site.

In this study, we evaluated the knowledge and perception and mitigation of hazards involved in radiological examinations, focusing on healthcare personnel who are not in radiation-related occupations, but who use ionising radiation as a part of their work. A questionnaire was applied to physicians, nurses, technicians and other staff working in different clinics that use radiation in their work, in order to evaluate their knowledge levels about ionizing radiation and their awareness about radiation doses resulting from radiological examinations. The statistical comparisons between the groups were analyzed with the Kruskal Wallis test using the SPSS program. Ninety two participants took part in the study. Their level of knowledge about ionizing radiation and doses in radiological examinations were found to be very weak. The number of correct answers of physicians, nurses, medical technicians and other personnel groups were 15.7±3.7, 13.0±4.0, 10.1±2.9 and 11.8±4.0, respectively. In the statistical comparison between the groups, the level of knowledge of physicians was found to be significantly higher than the level of the other groups (p=0.005). The present study demonstrated that general knowledge in relation to radiation, radiation protection, health risks and doses used for radiological applications are insufficient among health professions using with ionizing radiation in their work.

Currently, a considerable amount of work stress is present in school teachers, one of the occupational groups with the highest levels of job strain and burnout. As chronic stress produces significant modifications in emotional adjustment and neuroendocrine functioning, we aimed to investigate the role of these work stress constructs in the endocrine and mood responses of a group of female teachers during two working days (WD) at different moments in the academic year. We studied mood as well as levels of cortisol and testosterone, representative of a predominant catabolic or anabolic balance. Our results showed that higher "control" was associated with higher positive mood (p = .028 on WD1 and p = .057 on WD2) and salivary testosterone (Tsal) (p = .022 on WD1), whereas "demands" and "total job strain" were related to negative mood (p = .011 and p = .015, respectively). Participants with higher scores on "total burnout" and "emotional exhaustion" also had higher negative mood (p < .05 in all cases). Depersonalization correlated positively with negative mood (p = .019 and p = .006 on WD1 and WD2, respectively). Finally, personal accomplishment showed an inverse relationship with negative mood (p = .038 on WD2). These results are useful for job risk prevention and interventions that should focus on the control dimension of the job strain questionnaire and on personal accomplishment from the burnout scale.

These cases provide a good basis for discussions of scientific ethics, particularly with respect to the responsibilities of colleagues in collaborative projects. With increasing numbers of students working in cooperative or collaborative groups, there may be opportunities for more than just discussion—similar issues of responsibility apply to the members of such groups. Further, this is an area where, “no clear, widely accepted standards of behavior exist” (1). Thus there is an opportunity to point out to students that scientific ethics, like science itself, is incomplete and needs constant attention to issues that result from new paradigms such as collaborative research. Finally, each of us can resolve to pay more attention to the contributions we and our colleagues make to collaborative projects, applying to our own work no less critical an eye than we would cast on the work of those we don’t know at all.

To determine whether duration and degree of weight gain are differentially associated with diabetes risk in younger versus middle-aged black and white adults. We combined data from three cohort studies: Atherosclerosis Risk in Communities (ARIC), Coronary Artery Risk Development in Young Adults (CARDIA), and the Framingham Heart Study. A total of 17,404 participants (56% women; 21% black) were stratified by baseline age (younger: ≥30 and <45 years; middle-aged: ≥45 and <60 years) and examined for incident diabetes (median follow-up 9 years). Duration and degree of gain in BMI were calculated as "BMI-years" above one's baseline BMI. Diabetes incidence per 1,000 person-years in the younger and middle-aged groups was 7.2 (95% CI 5.7, 8.7) and 24.4 (22.0, 26.8) in blacks, respectively, and 3.4 (2.8, 4.0) and 10.5 (9.9, 11.2) in whites, respectively. After adjusting for sex, baseline BMI and other cardiometabolic factors, and age and race interaction terms, gains in BMI-years were associated with higher risk of diabetes in the younger compared with middle-aged groups: hazard ratios for 1-unit increase in log BMI-years in younger versus middle-aged blacks were 1.18 (P = 0.02) and 1.02 (P = 0.39), respectively (P for interaction by age-group = 0.047), and in whites were 1.35 (P < 0.001) and 1.11 (P < 0.001), respectively (P for interaction by age-group = 0.008). Although middle-aged adults have higher rates of diabetes, younger adults are at greater relative risk of developing diabetes for a given level of duration and degree of weight gain. © 2015 by the American Diabetes Association.

Objective: To explore the effect of occupational exposure to glyphosate on hepatorenal function. Methods: 526 workers who were occupationally exposed to glyphosate from 5 glyphosate-producing factories were selected as cases; and another 442 administrative staffs who were not exposed to glyphosate were selected as controls from April to November, 2014. All the subjects accepted occupational health examination. The concentration level of glyphosate in the air of workshop was detected and the time weighted average concentration (TWA) was calculated. And analyze the difference of hepatorenal fuction between case group and control group. Result: The age of the subjects in the case and control groups were separately (35.6±10.3), (34.3±9.7) years old, with the length of working for (6.5±5.7), (7.7±6.8) years. The TWA of glyphosate in the case group was between <0.03-48.91 mg/m(3), with the geometric mean at 3.78 mg/m(3). The overall rates of abnormal hepatic and renal function in the case group were 14.4% (76 cases) and 16.2% (85 cases), respectively; while those were 5.0% (22 cases) and 4.8% (21 cases), respectively in control group, and the difference showed statistical significance ( P <0.05). When TWA reached <0.03-6.00 mg/m(3), the difference of hepatorenal fuction between case group and control group showed statistical significance, and the rates of abnormal hepatic and renal function was 8.0% (36/447) and 9.8% (44/447) respectively in case group. When cumulative exposure level reached <1.56-68.64 g, the difference of hepatorenal fuction between case group and control group showed statistical significance, and the rates increased to 9.2% (37/404) and 10.4% (42/404) respectively in group of cases. Conclusion: Glyphosate can affect the hepatic and renal function among occupational exposure population, and there was an association between the effect and the exposure dose.

At times, we inevitably end up damaging root dentin which becomes a Gateway for infections like perforation, zipping, dentinal cracks and minute intricate fractures or even vertical root fractures, thereby resulting in failure of treatment. Several factors may be responsible for the formation of dentinal cracks like high concentration of sodium hypochlorite, compaction methods and various canal shaping methods. To compare and evaluate the effects of root canal preparation techniques and instrumentation length on the development of apical root cracks. Seventy extracted premolars with straight roots were mounted on resin blocks with simulated periodontal ligaments, exposing 1-2 mm of the apex followed by sectioning of 1mm of root tip for better visualization under stereomicroscope. The teeth were divided into seven groups of 10 teeth each - a control group and six experimental groups. Subgroup A & B were instrumented with: Stainless Steel hand files (SS) up to Root Canal Length (RCL) & (RCL -1 mm) respectively; sub group C & D were instrumented using ProTaper Universal (PTU) up to RCL and (RCL -1mm) respectively; subgroup E & F were instrumented using ProTaper Next (PTN) up to RCL & (RCL -1 mm) respectively. Stereomicroscopic images of the instrumentation sequence were compared for each tooth. The data was analyzed statistically using descriptive analysis by 'Phi' and 'Cramers' test to find out statistical significance between the groups. The level of significance was set at p< 0.05 using SPSS software. Stainless steel hand file group showed most cracks followed by ProTaper Universal & ProTaper Next though statistically not significant. Samples instrumented up to 1mm short of working length (RCL-1mm) showed lesser number of cracks. All groups showed cracks formation, the stainless steel group being the highest. Working 1mm short of apex reduces the incidence of crack formation.

The composition and structure of Humic acid (HA) is so heterogeneous that it brings significant barriers to investigate the interaction between HA and heavy metal ions. The isolation of HA with relatively homogeneity is a key to reveal the binding mechanisms between HA and heavy metals. In this work, ten HA fractions (HAs) were obtained by sequential alkali extraction procedure and nature differences of the extracted HAs were considered as explanatory factors for binding characteristics of Cu 2+ , Pb 2+ and Cd 2+ . The results indicate that more large molecular weight (MW) HA subunits, less carboxyl and phenolic group contents, weaker aromaticity and polarity were measured with increasing extractions, inducing weaker binding capacity of HAs. Ligand binding and bi-Langmuir models indicated that the sorption capacity and binding affinity of earlier extracted HAs were higher than the latter ones. The peak area changes at 3427, 1599, and 619 cm -1 pre- and post-adsorption in FTIR spectra suggested carboxyl, phenolic and nitrogen-containing groups were involved in the adsorption process. At the same time, the peak area difference between HAs and HAs-metal (ΔS) of phenolic groups were 8.22-20.50, 6.81-21.11 and 10.66-19.80% for Cu 2+ , Pb 2+ and Cd 2+ , respectively, ΔS of carboxyl groups 6.64-17.03, 8.96-16.82 and 9.45-17.85% for Cu 2+ , Pb 2+ and Cd 2+ , respectively, ΔS of nitrogen-containing groups 0.33-0.48, 0.20-1.38 and 0.31-0.59% for Cu 2+ , Pb 2+ and Cd 2+ , respectively. ΔS of phenolic and carboxyl groups were larger than those of nitrogen-containing groups, implying that these two groups were the predominant binding sites suppliers for metal ions, which were also supported by the results of correlation analysis. This work is helpful to insight the environmental impacts of natural organic matter and the fate of heavy metals in natural environment. Copyright © 2018 Elsevier Inc. All rights reserved.

To explore the characteristics of ecological executive function in school-aged children with idiopathic or probably symptomatic epilepsy and examine the effects of executive function on social adaptive function. A total of 51 school-aged children with idiopathic or probably symptomatic epilepsy aged 5-12 years at our hospital and 37 normal ones of the same gender, age and educational level were included. The differences in ecological executive function and social adaptive function were compared between the two groups with the Behavior Rating Inventory of Executive Function (BRIEF) and Child Adaptive Behavior Scale, the Pearson's correlation test and multiple stepwise linear regression were used to explore the impact of executive function on social adaptive function. The scores of school-aged children with idiopathic or probably symptomatic epilepsy in global executive composite (GEC), behavioral regulation index (BRI) and metacognition index (MI) of BRIEF ((62±12), (58±13) and (63±12), respectively) were significantly higher than those of the control group ((47±7), (44±6) and (48±8), respectively))(P<0.01). The scores of school-aged children with idiopathic or probably symptomatic epilepsy in adaptive behavior quotient (ADQ), independence, cognition, self-control ((86±22), (32±17), (49±14), (41±16), respectively) were significantly lower than those of the control group ((120±12), (59±14), (59±7) and (68±10), respectively))(P<0.01). Pearson's correlation test showed that the scores of BRIEF, such as GEC, BRI, MI, inhibition, emotional control, monitoring, initiation and working memory had significantly negative correlations with the score of ADQ, independence, self-control ((r=-0.313--0.741, P<0.05)). Also, GEC, inhibition, MI, initiation, working memory, plan, organization and monitoring had significantly negative correlations with the score of cognition ((r=-0.335--0.437, P<0.05)); Multiple stepwise linear regression analysis showed that BRI, inhibition and working memory were closely related with the social adaptive function of school-aged children with idiopathic or probably symptomatic epilepsy. School-aged children with idiopathic or probably symptomatic epilepsy may have significantly ecological executive function impairment and social adaptive function reduction. The aspects of BRI, inhibition and working memory in ecological executive function are significantly related with social adaptive function in school-aged children with epilepsy.

Clinical Application of the UK Working Party's Criteria for the Diagnosis of Atopic Dermatitis in the Chinese Population by Age Group.

Atopic dermatitis (AD) is a common inflammatory skin disease with an increasingly significant prevalence. The prevalence of AD depends greatly on how its diagnosis is done. The UK Working Party's diagnostic criteria for AD are simple and easy to apply without invasive laboratory tests. This study assessed the clinical utility of these criteria in China. Data were collected from 6208 patients at 31 tertiary hospitals in 13 Chinese provinces/municipalities from March 2014 to May 2014. . The agreement between the UK diagnostic criteria and the clinical records for AD was assessed by Cohen's kappa. The overall agreement between the UK diagnostic criteria and clinical diagnosis was fair (kappa = 0.40). A slightly better agreement was found in patients aged between 4 and 9 years (kappa = 0.48), while fair agreement was found in the group <4 years and the group ≥10 years (kappa = 0.27 and 0.39, respectively). Using the UK party's criteria as the standard, the sensitivity, specificity, positive predictive value, and negative predictive value of the clinical diagnosis of AD were 62.3%, 89.2%, 38.0%, and 95.7%, respectively. Our study indicates a modest ability among Chinese dermatologists to apply the UK Working Party's diagnostic criteria for AD, especially in patients aged <4 years and ≥10 years. Since there is no gold standard for AD diagnosis, it is important to determine how AD is identified when evaluating a diagnostic tool.

Early labor force exit is one of the major problems worldwide. The present study investigates the relationship between work ability and lifestyle. This study was conducted at a manufacturing plant in Tehran in 2012. All 851 male workers in this plant were included into the study and their work ability was assessed using the Work Ability Index (WAI). Based on the obtained scores, the participants were then classified into four work ability groups (poor, moderate, good, or excellent). Moreover, the participants' lifestyles were studied in three areas, including physical activity, cigarette smoking, and Body Mass Index (BMI). The average work ability index score was 42.07, ranging from 7-48. Among the participants, 6.4% (43), 6.5% (44), 38.3% (259), and 48.8% (330) were in the groups with poor, moderate, good, and excellent work ability, respectively. The results of logistic regression analysis showed that there is a significant relationship between work ability and lifestyle (cigarette smoking, BMI, and physical activity) even after adjustment for confounding variables (P<0.05). According to the results of the present study, there might be a relationship between work ability and lifestyle (physical activity, BMI, cigarette smoking). Therefore, it is recommended to implement a lifestyle quality enhancement program to improve work ability in working environments.

The Maslach Burn Out Inventory (1981) has been applied to a group of workers at three Psychosocial Centres at Milan and Trieste characterised by differing work styles. Point scores were related to a number of variables relative to the professional situation and work organisation. The same scores were related to the results of a questionnaire (Contessa 1987) on the operator's perception of his activity and on motivational factors with respect to the professional choice in actuality and at the beginning of the career. It was therefore possible to identify a set of positive correlations that indicate the presence of factors which increase or reduce B.O. Level.

Occupational stress in the multicultural workplace.

2011-08-01

Occupational stress is a well researched topic leading to the development of strong, viable models of workplace stress. However, there is a gap in the literature with respect to the applicability of this research to specific cultural groups, in particular those of immigrant status. The present paper reviews the extant literature regarding occupational stress from a multicultural perspective, evaluates the usefulness for existing models in the multicultural context, and discusses current issues with respect to increasing multiculturalism in the work environment. The authors conclude that workforce diversity is emerging as a pressing issue of organizational life and consequently, that future research needs to continue investigating whether current knowledge regarding workplace stress is fitting with the multicultural diversity of the present-day working population.

The main issue of the analyses are the nine killing series in the German language area. For the investigation legal documents concerning specific characteristics of victims, site of crime and offenders were evaluated. The respective fields of work were investigated concerning the working climate, the position of the offenders in their working group, conflicts in the work place and the handling of the first intern hints to suspective behaviour. It is derives from the case-by-case analyses if there are any preliminary warnings and if there are any commonalities with regard to the victims, the offenders and the respective fields of activity. Personal sensitivities, working conditions and permanent confrontation with human sufferings can be interlaced with each other in that way that the superficial motivation to help is abysmally reversed. In this repect a term of compassion, which confounds real sympathy and self-pity, is essential. © Georg Thieme Verlag KG Stuttgart · New York.

Addiction, agency, and the politics of self-control: doing harm reduction in a heroin users' group.

Gowan, Teresa; Whetstone, Sarah; Andic, Tanja

2012-04-01

Our 2007-2009 ethnography describes and analyses the practice of harm reduction in a heroin users' group in the midwestern United States. While dominant addiction interventions conceptualize the addict as powerless - either through moral or physical weakness - this group contested such "commonsense," treating illicit drug use as one of many ways that modern individuals attempt to "fill the void." Insisting on the destigmatization of addiction and the normalization of illicit drug use, the group helped its members work on incremental steps toward self-management. Although "Connection Points" had very limited resources to improve the lives of its members, our work suggests that the users' group did much to restore self-respect, rational subjectivity, and autonomy to a group historically represented as incapable of reason and self-control. As the users cohered as a community, they developed a critique of the oppressions suffered by "junkies," discussed their rights and entitlements, and even planned the occasional political action. Engaging with literature on the cultural construction of agency and responsibility, we consider, but ultimately complicate, the conceptualization of needle exchange as a "neoliberal" form of population management. Within the context of the United States' War on Drugs, the group's work on destigmatization, health education, and the practice of incremental control showed the potential for reassertions of social citizenship within highly marginal spaces.

Background Findings from clinical trials of proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors have led to concern that these drugs or the low levels of low-density lipoprotein (LDL) cholesterol that result from their use are associated with cognitive deficits. Methods In a subgroup of patients from a randomized, placebo-controlled trial of evolocumab added to statin therapy, we prospectively assessed cognitive function using the Cambridge Neuropsychological Test Automated Battery. The primary end point was the score on the spatial working memory strategy index of executive function (scores range from 4 to 28, with lower scores indicating a more efficient use of strategy and planning). Secondary end points were the scores for working memory (scores range from 0 to 279, with lower scores indicating fewer errors), episodic memory (scores range from 0 to 70, with lower scores indicating fewer errors), and psychomotor speed (scores range from 100 to 5100 msec, with faster times representing better performance). Assessments of cognitive function were performed at baseline, week 24, yearly, and at the end of the trial. The primary analysis was a noninferiority comparison of the mean change from baseline in the score on the spatial working memory strategy index of executive function between the patients who received evolocumab and those who received placebo; the noninferiority margin was set at 20% of the standard deviation of the score in the placebo group. Results A total of 1204 patients were followed for a median of 19 months; the mean (±SD) change from baseline over time in the raw score for the spatial working memory strategy index of executive function (primary end point) was -0.21±2.62 in the evolocumab group and -0.29±2.81 in the placebo group (P<0.001 for noninferiority; P=0.85 for superiority). There were no significant between-group differences in the secondary end points of scores for working memory (change in raw score, -0.52 in the evolocumab group and -0.93 in the placebo group), episodic memory (change in raw score, -1.53 and -1.53, respectively), or psychomotor speed (change in raw score, 5.2 msec and 0.9 msec, respectively). In an exploratory analysis, there were no associations between LDL cholesterol levels and cognitive changes. Conclusions In a randomized trial involving patients who received either evolocumab or placebo in addition to statin therapy, no significant between-group difference in cognitive function was observed over a median of 19 months.

Objectives: This study aimed to evaluate the effectiveness of supervised exercise among nurses conducting shift work for health promotion. Methods: A total of 30 healthy female nurses conducting shift work participated in this study and they were randomly assigned to one of the following 2 groups: The supervised exercise group (SG; participants exercised under the supervision of a physical therapist (PT)) and the voluntary exercise group (VG; participants exercised without supervision). The study participants were asked to exercise twice/week for 12 weeks for 24 sessions. The primary outcome was aerobic fitness, and the secondary outcomes were muscle strength, anthropometric data, biochemical parameters, and mental health. We compared all the outcomes before and after the intervention within each group and between both groups at follow-up. Results: Aerobic fitness increased in the SG whereas it decreased in the VG, but these changes were not statistically significant (p=0.053 and 0.073, respectively). However, the between-group difference was significant in the intervention effect (p=0.010). Muscle strength, high-density lipoprotein cholesterol and metabolic profile (high-molecular weight adiponectin), and depressive symptom significantly improved in the SG over time, even though the SG exercised less as compared with the VG. Moreover, significant differences in muscle strength, and low-density lipoprotein cholesterol and reactive oxygen metabolite levels were observed between both groups, and these parameters were better in the SG than in the VG. Conclusions: Our data-suggest the effectiveness of exercise supervised by a PT at the workplace of nurses conducting shift work for health promotion. PMID:28638000

The aim of this study is to develop, implement and evaluate an education programme enabling the pedagogic staff of employment promotion agencies to integrate health promotion approaches und activities in vocational training programmes. The evaluation of the education programme is based on Kirkpatrick's 4 levels training evaluation model. Besides the participants' verbal end of session feedback, a standardised questionnaire was used at the end of the education programme and after 3 months practical experience. Process evaluation included the implementation level of the methods learned. From a total of 71 participants, 56 completed the first and 31 the second questionnaire (return rate 79% and 44%, respectively). The participants' mean age was 42 years, 80% were female. Only 22% of them integrated health topics systematically into their daily work. A 3-day basic training followed by case conferences during practical work was developed to transfer knowledge and practical competence in person-to-person talks and group activities (so called FIT-counselling and FIT-group). For 96% of participants, their expectations regarding the education programme were met completely or predominantly. 91% indicated a rise in motivation to work as health coach. When rating the training material, 96% judged it helpful for implementation/transfer. Many participants marked the education programme as being too short and wished more time for the topic of "mental health" and exchange of experiences. The follow-up after 3 months on-the-job training revealed that 84 and 97%, respectively, found FIT-counselling and FIT-groups helpful for their daily work. In all employment promotion agencies FIT-counselling and FIT-groups were implemented. Our results affirm the need for and prove the acceptance of education programmes enabling the pedagogic staff of job-training programmes to deliver health coaching. Periodic case conferences take into account the participants' request for more exchange of experiences, facilitate implementation and contribute to quality and sustainability. Further development of the education programme is ongoing. © Georg Thieme Verlag KG Stuttgart · New York.

The theme of the present work is to evaluate the protective effect of nanoencapsulated quercetin (NEQ) against chlorpyrifos (CPF)-induced hepatic damage and immune alterations in animals. Nanoparticles (NP) drug encapsulation was prepared. Forty male Wistar rats were divided into eight groups. Two groups served as control and CPF (13.5 mg/kg) treatment for 28 days. Other three groups were free quercetin (QC), NP and NEQ treated with 3 mg/kg respectively for 15 days; whereas remaining three groups received treatment of CPF and QC, NP, NEQ, respectively, for 15 days. The results show that significantly altered oxidative stress in the liver tissue and liver enzyme parameters in blood and immune responses in CPF-treated rats compared to controls. Administration of NEQ attenuated biochemical and immunological parameters. The liver histopathological analysis confirmed pathological improvement. Hence, use of NEQ appeared to be beneficial to a great extent in attenuating and restoring hepatic oxidative damage and immune alteration sustained by pesticide exposure. © 2018 Wiley Periodicals, Inc.

This study evaluated the levels of exposure to polycyclic aromatic hydrocarbons (PAHs) and their relationship with oxidative DNA damage among Vietnamese coke-oven workers. We collected urine from 36 coke-oven workers (exposed group) at the beginning and end of the shift on 2 consecutive days. We also collected urine from 78 medical staff (control group). Information was collected by questionnaire about smoking status, drinking habit, and working position. Urinary 1-hydroxypyrene (1-OHP) and 8-hydroxydeoxyguanosine (8-OH-dG) were measured using HPLC. All statistical analyses were performed with SPSS version 19. Urinary 1-OHP was significantly higher in the coke-oven workers than in the control group (p<0.05). Top-oven workers had the highest levels of internal exposure to PAHs, followed by side-oven and then bottom-oven workers (5.41, 4.41 and 1.35 ng/mg creatinine, respectively, at the end of the shift on day 2). Urinary 8-OH-dG was significantly higher in top- and side-oven workers at the end of the shift on day 2 (4.63 and 5.88 ng/mg creatinine, respectively) than in the control group (3.85 ng/mg creatinine). Based on a multi-regression analysis, smoking status had a significant effect on urinary 8-OH-dG (p=0.049). Urinary 1-OHP tended to have a positive correlation with urinary 8-OH-dG (p=0.070). Vietnamese coke-oven workers were exposed to PAHs during their work shift. Urinary 1-OHP exceeded the recommended limit, and elevated oxidative DNA damage occurred in top- and side-oven workers on the second day of work. A tendency for positive correlation was found between urinary 1-OHP and urinary 8-OH-dG.

1. Body-weight, body height and skinfold measurements were taken in 419 adult males working in the UK offshore oil industry. Percentage body fat was estimated from skinfold thicknesses and the Quetelet index (weight:height) determined. 2. The prevalence of overweightness, assessed from the Quetelet index, in the age groups 20-29, 30-39 and 40-49 years was 31.6, 50.0 and 66.2% respectively. The Office of Population Census and Surveys (1981) showed that for age-matched groups, the incidence of overweightness in an onshore population was 26, 40 and 50% respectively. 3. The percentage body fat for each respective age group was greater than that reported for an age-matched onshore population. 4. The Quetelet index was significantly related to body fat (r 0.765, P less than 0.0001) and poorly correlated with height, thus this weight:height relation may be utilized in the assessment of overweightness in offshore personnel. 5. In conclusion it appears that the offshore population had a higher percentage body fat than their onshore peers and that the prevalence of overweightness was also greater.

To report on the current career destination of the University of Ghana Medical School (UGMS) qualified doctors in the year groups, 1998, 2000, 2003, 2005 and 2008. Interview of doctors from each year group currently working at the Korle-Bu Teaching Hospital corroborated by phone calls to the doctors. All Ghanaian doctors from each graduating year group. 1. Current location of employment in Ghana or abroad, 2. Gender ratios of the doctors retained in Ghana. Three hundred and seventy-two (372) UGMS doctors consisting of 353 Ghanaians and 19 foreign students graduated over the five year groups. Of the 353 Ghanaians, 113 emigrated, while all but one of the 240 living in Ghana, practice medicine. The retention rate improved from 54.2% in 1998 to 86.3% in 2008. The overall retention rate however is 68.0% while the retention rates for the male and female doctors were 69.3% and 64.6% respectively. Of the 177 doctors practicing in Ghana from the first 4 year-groups (i.e. 1998, 2000, 2003 and 2005,) 139 (i.e. 31, 31, 34 and 43 from the respective year groups) have either completed postgraduate training or are in the residency training programme. Thus 78.5% of these doctors working in Ghana have opted for postgraduate training. The establishment of the GCPS and to a lesser extent the introduction of the ADHA before it appear to have slowed down the medical brain drain as more and more doctors avail themselves of the local opportunities. The GCPS therefore needs supporting effectively in order to continue to be a strong incentive for the retention of doctors in Ghana, apart from helping to staff district general hospitals with specialists.

Although the prevalence of cancer is increasing, it is no longer synonymous with death. The number of cancer survivors is estimated to be increasing due to development in medical treatments and social programs; cancer survivors are increasingly returning to work after long-term unemployment. Thus, we examined the quality of life (QOL) and the factors associated with return of cancer survivors to the workplace. This study was performed using the 2008 Community Health Survey administered by the Korea Centers for Disease Control and Prevention (N=548). We used Chi-square tests to compare demographic variables based on self-perceived health status, and analysis of variance (ANOVA) to compare QOL scores among groups. We also performed a mixed-model analysis of the relationship between QOL and factors at the workplaces of cancer survivors. Based on the results of our study, the overall QOL of cancer survivors was associated with 'mutual respect', 'free emotional expression', occupation, and age. Moreover, different trends of QOL according to self-perceived health were identified on additional analysis. In the 'bad' self-perceived health group, QOL was significantly different according to income. The QOL of cancer survivors in the low-income group was lower than in the other groups. Conversely, the 'normal' group had a lower QOL caused by 'no mutual respect' and "no free emotional expression" in the workplace. The QOL in the 'good' group based on self-perceived health was higher in the younger age group. There may be a significant relationship between QOL and workplace factors for cancer survivors, although further study is needed to investigate this relationship in detail. This may facilitate formulation of policy and efforts to prevent and manage the decline in the QOL of cancer survivors returning to work.

The most important biothiols include glutathione, homocysteine (HCY), cysteine and proteins. The aim of the presented study was to evaluate the influence of lead on the biothiol turnover--the concentration of HCY and protein sulfhydryl groups (P-SH) in the serum and reduced glutathione (G-SH) in erythrocytes--in individuals (employees of metal works) exposed to lead and to evaluate its probable oxidative disorders, measured as the carbonyl protein (CP) concentration in serum. The exposed workers were divided into 2 subgroups: 1) low lead exposure (LPb), with a lead concentration in the blood (PbB) of 20-45 µg dl(-1) (n= 102), and 2) high lead exposure (HPb), with PbB = 45-60 µg dl(-1) (n= 81). The control group consisted of 72 office workers or other healthy subjects with no history of occupational exposure to lead. All the controls had normal PbB (<10 μg dl(-1)) and ZPP (<2.5 μg dl(-1)) levels. The concentration of HCY was higher in the LPb group by 11% and in the HPb group by 26%, compared with the control group (n=72). The CP concentration in these 2 groups was more than twice as high as that of the control group, with 108% and 125% increases for the LPb and HPb groups, respectively; G-SH was lower by 6.6% and 7.4% for the LPb and HPb groups, respectively; P-SH was lower by 8.2% and 13% for the LPb and HPb groups, respectively. Lead decreases levels of glutathione and protein thiol groups. Lead-induced oxidative stress contributes to the observed elevation of protein carbonyl groups. Besides, lead poisoning seems to be associated with hyperhomocysteinaemia, which may promote the development of atherosclerosis.

This study aimed to evaluate the effects of an intervention on objective working-hour characteristics. The intervention involved making modifications to the collective agreement that would limit employees' entitlement to time off as compensation. The intervention group consisted of 493 and the control group of 2,303 health and social care shift workers, respectively. We analysed the objective pay roll-based working-hour data for 2012-2013, which we obtained from employers' records, using the repeated measures mixed model. The changes in objective working-hour characteristics were small, but systematic. The intervention had some positive effects: the amount of short recovery periods (<28 h) after the last night shift decreased from 5% to 3%, and the amount of working weeks of over 48 h decreased from 19% to 17%. The realization of employees' shift preferences increased from 18% to 20%. However, in contrast, consecutive work shifts and the number of scheduled absences increased and days off decreased, suggesting less time for recovery and thus a negative trend in shift ergonomics. When planning shifts, nursing management should avoid regulations that promote specific unhealthy shift characteristics, that is, consecutive work shifts and less days off.

Studies on violence in the work of security guards are largely lacking. This study is unique in that it focuses on security guards (n=1,010) in Finland, and assesses the different forms, prevalence, and risk factors of the work-related violence they often face. Information to a survey instrument was obtained by first interviewing 30 volunteers. Then we made a cross-sectional mailed survey that was sent to a randomized group of 2,000 security guards. The response rate was 52. We found the prevalence of verbal aggression, threats of assault, and physical acts against security guards at least once a month to be 39%, 19%, and 15% respectively. As regards risk factors and who is most at risk, our results show that male gender, young age, low work experience, late working hours, and time pressure were associated with all three forms of work-related violence. Unlike other forms of violence, verbal aggression was highly prevalent outside the metropolitan area and directed towards both more and less experienced security guards. In prevention policies for violence, it is important to identify high-risk groups such as those who have less work experience.

Work-related physical assaults or violence has severely impacted on the safety of the work environment and employees' mental health. The aim of the present study was to investigate the prevalence of physical assaults, the effect of socioeconomic status (SES) on it and depression associated with it in employees working at large companies. A total of 22,770 Japanese employees responded to a self-administered questionnaire including SES (educational status and occupational status), violence victimization, worksite social support and depression (response rate, 85%). The 12-month prevalence of physical assaults and depression was examined using a single question and the Center for Epidemiologic Studies Depression scale, respectively. The prevalence of physical assaults was 1.8% both in males and females. Although the risk of exposure to physical assaults was 2-3 times higher in the blue-collar group than in the manager group, the association of exposure to physical assaults with depression was stronger in the manager and white-collar worker group (Prevalence ratio [PR]=2.1 in males; 1.8 in females) than in the blue-collar worker group (PR=1.7 in males; 1.5 in females) after adjusting demographic and occupational covariates. A similar pattern was observed for education in males; the association was stronger than in the lower education group (PR=2.1 and 1.8). Low SES is a risk factor of exposure to physical assaults, however, the association of physical assaults with depression was significantly greater among company employees of higher SES than those of lower SES.

Abstract Leptomeningeal metastases (LM) currently lack standardization with respect to response assessment. A Response Assessment in Neuro-Oncology (RANO) working group with expertise in LM developed a consensus proposal for evaluating patients treated for this disease. Three basic elements in assessing response in LM are proposed: a standardized neurological examination, cerebral spinal fluid (CSF) cytology or flow cytometry, and radiographic evaluation. The group recommends that all patients enrolling in clinical trials undergo CSF analysis (cytology in all cancers; flow cytometry in hematologic cancers), complete contrast-enhanced neuraxis MRI, and in instances of planned intra-CSF therapy, radioisotope CSF flow studies. In conjunction with the RANO Neurological Assessment working group, a standardized instrument was created for assessing the neurological exam in patients with LM. Considering that most lesions in LM are nonmeasurable and that assessment of neuroimaging in LM is subjective, neuroimaging is graded as stable, progressive, or improved using a novel radiological LM response scorecard. Radiographic disease progression in isolation (ie, negative CSF cytology/flow cytometry and stable neurological assessment) would be defined as LM disease progression. The RANO LM working group has proposed a method of response evaluation for patients with LM that will require further testing, validation, and likely refinement with use. PMID:28039364

In this study we aimed to investigate the genotoxic effects of antineoplastic agents in occupationally exposed oncology nurses. Genotoxic effects mean the disruptive effects in the integrity of DNA and they are associated with cancer development. Biomonitoring of health care workers handling antineoplastic agents is helpful for the evaluation of exposure to cytostatics. The study included an exposed and two control groups. The exposed group (n=9) was comprised of oncology nurses. The first (n=9) and second (n=10) control groups were comprised of subjects who did not come into contact with antineoplastic drugs working respectively in the same department with oncology nurses and in different departments. Genotoxicity evaluation was performed using SCE analysis. After applying culture, harvest and chromosome staining procedures, a total of 25 metaphases were analyzed per person. Kruskal Wallis test was used to perform statistical analysis. A statistically significant difference of sister chromatid exchange frequencies was not observed between the exposed and control groups. Lack of genotoxicity in medical oncology nurses might be due to good working conditions with high standards of technical equipment and improved personal protection.

Background The Royal College of Physicians and Surgeons of Canada specifies both respect for diversity as a requirement of professionalism and culturally sensitive provision of medical care. The purpose of the present study was to evaluate the perception of preparedness and attitudes of medical residents to deliver cross-cultural care. Methods The Cross Cultural Care Survey was sent via e-mail to all Faculty of Medicine residents (approx. 450) in an academic health sciences centre. Comparisons were made between psychiatry residents, family medicine residents, and other residency groups with respect to training, preparedness, and skillfulness in delivering cross-cultural care. Results Seventy-three (16%) residents responded to the survey. Residents in psychiatry and family medicine reported significantly more training and formal evaluation regarding cross-cultural care than residents in other programs. However, there were no significant differences in self-reported preparedness and skillfulness. Residents in family medicine were more likely to report needing more practical experience working with diverse groups. Psychiatry residents were less likely to report inadequate cross-cultural training. Conclusion While most residents reported feeling skillful and prepared to work with culturally diverse groups, they report receiving little additional instruction or formal evaluation on this topic, particularly in programs other than psychiatry and family medicine.

[Patient-centered approaches to understanding, transformation and solution of team conflicts in the psychiatric clinic within the scope of the Balint group concept].

Drees, A

1987-08-01

The working climate and therapeutic possibilities in a hospital are determined, among other factors, by emotional processes in everyday ward routine. Team conflicts and their solution are not infrequently reflections of the open-mindedness of a hospital towards the complexity of these processes. However, the complex interlocking of transference processes with rôle-specific and personality-conditioned behaviour patterns makes it more difficult to understand and make use of these emotional processes within the team. We present a specific attempt to working up emotional conflicts in a patient-centred approach via focussing on self-rating of the team workers in respect of mood, feeling tone and imagination. Specific internal Balint groups are the fulcrum. To distinguish this method from the theory of object-directed transference of emotions and constructions of relations, the theoretical basis of this group method is seen in the systemic paradigm with which patient-focussed solution functions are obtained in respect of process orientation and instrumental part functions of the team workers. In this connection it was explored to what extent the following factors can be interpreted as patient-induced phenomena: therapeutic and rôle behaviour, hospital structures and administrative squabbles, internal and external walls of a mental hospital.

Although the treatment of Parkinson's disease via subthalamic stimulation yields remarkable improvements in motor symptoms, its effects on memory function are less clear. In this context, we previously demonstrated dissociable effects of levodopa therapy on parkinsonian performance in spatial and nonspatial visual working memory. Here we used the same protocol with an additional, purely motor task to investigate visual memory and motor performance in 2 groups of patients with Parkinson's disease with or without subthalamic stimulation. In each stimulation condition, subjects performed a simple motor task and 3 successive cognitive tasks: 1 conditional color-response association task and 2 visual (spatial and nonspatial) working memory tasks. The Parkinson's groups were compared with a control group of age-matched healthy subjects. Our principal results demonstrated that (1) in the motor task, stimulated patients were significantly improved with respect to nonstimulated patients and did not differ significantly from healthy controls, and (2) in the cognitive tasks, stimulated patients were significantly improved with respect to nonstimulated patients, but both remained significantly impaired when compared with healthy controls. These results demonstrate selective effects of subthalamic stimulation on parkinsonian disorders of motor and visual memory functions, with clear motor improvement for stimulated patients and a partial improvement for their visual memory processing.

Background: Falling asleep at work is receiving increasing attention as a cause of work accidents. Aims: To investigate which variables (related to work, lifestyle, or background) are related to the tendency to fall asleep unintentionally, either during work hours, or during leisure time. Methods: 5589 individuals (76% response rate) responded to a questionnaire. A multiple logistic regression analysis of the cross sectional data was used to estimate the risk of falling asleep. Results: The prevalence for falling asleep unintentionally at least once a month was 7.0% during work hours and 23.1% during leisure time. The risk of unintentional sleep at work was related to disturbed sleep, having shift work, and higher socioeconomic group. Being older, being a woman, and being a smoker were associated with a reduced risk of unintentionally falling asleep at work. Work demands, decision latitude at work, physical load, sedentary work, solitary work, extra work, and overtime work were not related to falling asleep at work. Removing "disturbed sleep" as a predictor did not change the odds ratios of the other predictors in any significant way. With respect to falling asleep during leisure time, disturbed sleep, snoring, high work demands, being a smoker, not exercising, and higher age (>45 years) became risk indicators. Conclusion: The risk of involuntary sleep at work is increased in connection with disturbed sleep but also with night work, socioeconomic group, low age, being a male, and being a non-smoker.

Bakke, Berit; Stewart, Patricia; Eduard, Wijnand

2002-11-01

In tunnel construction work, dust is generated from rock drilling, rock bolting, grinding, scaling, and transport operations. Other important dust-generating activities are blasting rock and spraying wet concrete on tunnel walls for strength and finishing work. The aim of this study was to identify determinants of dust exposure in tunnel construction work and to propose control measures. Personal exposures to total dust, respirable dust, and alpha-quartz were measured among 209 construction workers who were divided into 8 job groups performing similar tasks: drill and blast workers, shaft drilling workers, tunnel boring machine workers, shotcreting operators, support workers, concrete workers, outdoor concrete workers, and electricians. Information on determinants was obtained from interviewing the workers, observation by the industrial hygienist responsible for the sampling, and the job site superintendent. Multivariate regression models were used to identify determinants associated with the dust exposures within the job groups. The geometric mean exposure to total dust, respirable dust, and alpha-quartz for all tunnel workers was 3.5 mg/m(3) (GSD = 2.6), 1.2 mg/m(3) (GSD = 2.4), and 0.035 mg/m(3) (GSD = 5.0), respectively. A total of 15 percent of the total dust measurements, 5 percent of the respirable dust, and 21 percent of the alpha-quartz exceeded the Norwegian OELs of 10 mg/m(3), 5 mg/m(3), and 0.1 mg/m(3), respectively. Job groups with highest geometric mean total dust exposure were shotcreting operators (6.8 mg/m(3)), tunnel boring machine workers (6.2 mg/m(3)), and shaft drilling workers (6.1 mg/m(3)). The lowest exposed groups to total dust were outdoor concrete workers (1.0 mg/m(3)), electricians (1.4 mg/m(3)), and support workers (1.9 mg/m(3)). Important determinants of exposure were job group, job site, certain tasks (e.g., drilling and scaling), the presence of a cab, and breakthrough of the tunnel. The use of ventilated, closed cabs appeared to be the single most important control measure for lowering exposures.

The purpose of this study was to investigate the effectiveness of the advance organiser model (AOM) on students' academic achievement in learning work and energy. The design of the study was quasi-experimental pretest-posttest nonequivalent control groups. The total population of the study was 139 students of three sections in Endabaguna preparatory school in Tigray Region, Ethiopia. Two sections with equivalent means on the pretest were taken to participate in the study purposely and one section assigned as the experimental group and the other section assigned as the control group randomly. The experimental group was taught using the lesson plan based on the AOM, and the control group was taught using the lesson plan based on the conventional teaching method. Pretest and posttest were administered before and after the treatment, respectively. Independent sample t-test was used to analyse the data at the probability level of 0.05. The findings of the study showed that the AOM was more effective than the conventional teaching method with effect size of 0.49. This model was also effective to teach male and female students and objectives namely understanding and application. However, both methods were equally important to teach work and energy under the objective knowledge level.

Lifetime Occupation and Late-Life Cognitive Performance Among Women.

We examined whether women who had regular jobs throughout life performed better cognitively than older adult housewives. Linear regression was used to compare global cognitive performance scores of housewives (G1) and women exposed to work of low (G2) and high (G3) complexity. The sample comprised 477 older adult Brazilian women, 430 (90.4%) of whom had performed lifelong jobs. In work with data, the G2 group's cognitive performance scores were 1.73 points higher (p =.03), and the G3 group scored 1.76 points (p =.02) higher, than the G1. In work with things and with people, the G3 scored, respectively, 2.04 (p <.01) and 2.21 (p <.01) cognitive test points higher than the G1. Based on our findings we suggest occupation of greater complexity is associated with better cognitive performance in women later in life.

Excessive sleepiness and self-reported shift work disorder: an Internet survey of shift workers.

To compare excessive sleepiness and quality of life (QoL) scores in shift workers who report having a diagnosis of shift work disorder (SWD) with those who report having no such diagnosis. An Internet-based survey was conducted between March and April 2009 that included shift workers with or without a self-reported diagnosis of SWD. Participation required working ≥ 21 hours/week for 2 weeks prior, a diagnosis of SWD or a score of ≥ 10 on the Epworth Sleepiness Scale, and a score of ≥ 5 on any subscale of the Sheehan Disability Scale. Surveys included 260 shift workers (103 with an SWD diagnosis and 157 without an SWD diagnosis). Diagnosed and undiagnosed respondents demonstrated similar Epworth Sleepiness Scale (13.7 vs 13.6, respectively) and Karolinska Sleepiness Scale (6.0 vs 5.5, respectively) scores. Sheehan Disability Scale social life and family life scores were similar between the 2 groups, although diagnosed respondents had a greater mean Sheehan Disability Scale work disability score compared with undiagnosed respondents (6.7 vs 5.5; P < 0.0001). Quality of life was more impaired in diagnosed patients in terms of ability to drive safely, propensity for accidents, work performance, and anxiety (P ≤ 0.039 vs undiagnosed). Work-related accidents (16% vs 5%; P = 0.0076) and injuries at work (17% vs 7%; P = 0.0233) were also reported by more diagnosed respondents than by undiagnosed respondents. Many respondents used caffeine and 57% of diagnosed respondents received prescription medication to treat symptoms of SWD. Individuals with diagnosed SWD demonstrated impairment in QoL and reported more work-related accidents and injuries, although many measures of QoL and prescription drug use were similar between groups. Shift work disorder is underrecognized by clinicians and patients, resulting in undertreatment, despite the availability of several behavioral and therapeutic treatment options.

To study the prevalence of occupational musculoskeletal disorders (OMSD) of male steelworkers and explore its occupational and individual risk factors. 1620 male workers from a steel mill were selected as subjects through random cluster sampling in 2010. A revised Nordic Musculoskeletal disorder standard questionnaire and a questionnaire from National Institute for Occupational and Health of the Netherlands were used to ask and record the OMSD and its risk factors. The questionnaires were filled in by the workers. Annual prevalence of OMSD in different parts of the body were counted according to different age, working years and educational level, logistic regression was used to analyze its influence factors. OMSD in these workers primarily located in waist, neck and shoulders, annual prevalence were 51.0% (825), 48.5% (785) and 37.7% (610) respectively. Annual prevalence of other body parts were 28.0% (454) for back, 23.6% (383) for knee, 21.0% (341) for wrist, 17.9% (290) for ankle/foot, 14.1% (229) for elbow and 12.7% (205) for coxa. The annual prevalence of OMSD for each part tended to increase with age, mainly in waist and neck. Of the different age groups ≤ 24, 25 - 29, 30 - 34, 35 - 39, 40 - 44, 45 - 49, ≥ 50, the annual prevalence in waist was 26.4% (43/163), 37.8% (71/188), 52.8% (162/307), 55.6% (160/288), 53.8% (99/184), 55.9% (80/143), 61.6% (204/331) respectively (χ(2) = 72.5, P < 0.05); correspondingly, the annual prevalence in neck was 22.7% (37/163), 40.4% (76/188), 50.2% (154/307), 48.6% (140/288), 56.0% (103/184), 53.1% (76/143), 57.7% (191/331) respectively (χ(2) = 65.3, P < 0.05). The annual prevalence of OMSD increased with the working years. Of the different working years groups ≤ 4, 5 - 9, 10 - 14, 15 - 19, 20 - 24, 25 - 29, ≥ 30, the annual prevalence in waist was 30.2% (85/281), 46.2% (66/143), 56.4% (162/287), 56.8% (137/241), 50.6% (78/154), 59.2% (90/152), 60.7% (173/285) respectively (χ(2) = 71.3, P < 0.05);correspondingly, the annual prevalence in neck was 28.8% (81/281), 49.0% (70/143), 52.6% (151/287), 50.2% (121/241), 51.9% (80/154), 53.9% (82/152), 59.3% (169/285) respectively (χ(2) = 61.5, P < 0.05). The annual prevalence of OMSD decreased with education level. Of the different groups of education level (junior high school level and below, senior high school level, university level or above), the OMSD prevalence in waist was 61.5% (176/286), 61.9% (359/692), 44.2% (272/615) respectively (χ(2) = 26.0, P < 0.05);correspondingly, the annual prevalence in neck was 56.3% (161/286), 50.0% (346/692), 42.3% (260/615)respectively (χ(2) = 21.2, P < 0.05). Univariate logistic regression showed that the work load factors such as the working years ≥ 30 (OR = 3.562, 95%CI: 2.514 - 5.046), maintain substantial stoop for a long time (OR = 2.003, 95%CI: 1.612 - 2.488), often stooping with vast scale (OR = 1.897, 95%CI: 1.557 - 2.312), and torso repeating same action many times per minute (OR = 1.870, 95%CI: 1.529 - 2.288) could increase the annual prevalence of OMSD in waist most likely (P < 0.05). The working years ≥ 30 (OR = 3.597, 95%CI: 2.535 - 5.105), neck leaning forward (OR = 2.455, 95%CI: 2.010-2.99), neck leaning back (OR = 1.999, 95%CI: 1.569 - 2.546), and neck rotation (OR = 2.381, 95%CI: 1.907 - 2.972) were main risk factors causing OMSD in neck (P < 0.05). The most serious musculoskeletal disorders of male steelworkers were waist and neck pain. Personal factors such as age, working years, work load factors such as harmful working postures, manual heavy lifting, and labour organizational factors such as work overtime were the main risk factors of musculoskeletal disorders to the male steelworkers.

It is unknown whether the height of a heel-rise performed in the single-leg standing heel-rise test 1 year after an Achilles tendon rupture (ATR) correlates with ankle biomechanics during walking, jogging, and jumping in the long-term. To explore the differences in ankle biomechanics, tendon length, calf muscle recovery, and patient-reported outcomes at a mean of 6 years after ATR between 2 groups that, at 1-year follow-up, had less than 15% versus greater than 30% differences in heel-rise height. Cohort study; Level of evidence, 3. Seventeen patients with less than 15% (<15% group) and 17 patients with greater than 30% (>30% group) side-to-side difference in heel-rise height at 1 year after ATR were evaluated at a mean (SD) 6.1 (2.0) years after their ATR. Ankle kinematics and kinetics were sampled via standard motion capture procedures during walking, jogging, and jumping. Patient-reported outcome was evaluated with Achilles tendon Total Rupture Score (ATRS), Physical Activity Scale (PAS), and Foot and Ankle Outcome Score (FAOS). Tendon length was evaluated by ultrasonography. The Limb Symmetry Index (LSI = [Injured Side ÷ Healthy Side] × 100) was calculated for side differences. The >30% group had significantly more deficits in ankle kinetics during all activities compared with patients in the <15% group at a mean of 6 years after ATR (LSI, 70%-149% and 84%-106%, respectively; P = .010-.024). The >30% group, compared with the <15% group, also had significantly lower values in heel-rise height (LSI, 72% and 95%, respectively; P < .001) and heel-rise work (LSI, 58% and 91%, respectively; P < .001) and significantly larger side-to-side difference in tendon length (114% and 106%, respectively; P = .012). Achilles tendon length correlated with ankle kinematic variables ( r = 0.38-0.44; P = .015-.027) whereas heel-rise work correlated with kinetic variables ( r = -0.57 to 0.56; P = .001-.047). LSI tendon length correlated negatively with LSI heel-rise height ( r = -0.41; P = .018). No differences were found between groups in patient-reported outcome ( P = .143-.852). Height obtained during the single-leg standing heel-rise test performed 1 year after ATR related to the long-term ability to regain normal ankle biomechanics. Minimizing tendon elongation and regaining heel-rise height may be important for the long-term recovery of ankle biomechanics, particularly during more demanding activities such as jumping.

To evaluate the clinical utility of a new navigation technique for percutaneous renal puncture using real-time virtual sonography (RVS) during endoscopic combined intrarenal surgery. Thirty consecutive patients who underwent endoscopic combined intrarenal surgery for renal calculi, between April 2014 and July 2015, were divided into the RVS-guided puncture (RVS; n = 15) group and the ultrasonography-guided puncture (US; n = 15) group. In the RVS group, renal puncture was repeated until precise piercing of a papilla was achieved under direct endoscopic vision, using the RVS system to synchronize the real-time US image with the preoperative computed tomography image. In the US group, renal puncture was performed under US guidance only. In both groups, 2 urologists worked simultaneously to fragment the renal calculi after inserting the miniature percutaneous tract. The mean sizes of the renal calculi in the RVS and the US group were 33.5 and 30.5 mm, respectively. A lower mean number of puncture attempts until renal access through the calyx was needed for the RVS compared with the US group (1.6 vs 3.4 times, respectively; P = .001). The RVS group had a lower mean postoperative hemoglobin decrease (0.93 vs 1.39 g/dL, respectively; P = .04), but with no between-group differences with regard to operative time, tubeless rate, and stone-free rate. None of the patients in the RVS group experienced postoperative complications of a Clavien score ≥2, with 3 patients experiencing such complications in the US group. RVS-guided renal puncture was effective, with a lower incidence of bleeding-related complications compared with US-guided puncture. Copyright © 2017 Elsevier Inc. All rights reserved.

Analysis of the burden of gastro-oesophageal reflux disease (GERD) in relation to the severity and frequency of symptoms is essential to identify individuals and groups in whom targeted management is justified. To describe the relationship between symptoms of GERD and self-reported health-related quality of life (HRQL), work productivity, healthcare utilization and concomitant diseases. US respondents to the Internet-based 2004 National Health and Wellness Survey who had self-reported GERD (n = 10,028, mean age: 52 years, 58% female) were age- and gender-matched to a control group without GERD (n = 10,028). Respondents with GERD were classified according to symptom severity and frequency. HRQL and productivity were assessed using the Short-Form 8 survey (SF-8) and Work Productivity and Activity Impairment questionnaire, respectively. Symptom frequency increased with increasing symptom severity. Compared with controls, respondents with GERD had more concomitant diseases [mean difference (MD): 1.6], lower SF-8 physical and mental health scores (MD: 4.1 units and 3.1 units, respectively), increased absenteeism (MD: 0.9 h/week), reduced percent productivity at work (MD: 7.5%) and increased healthcare utilization. All tested variables deteriorated with increasing symptom severity and/or frequency. Increasing severity and frequency of GERD symptoms is associated with more concomitant diseases, lower HRQL, lower work productivity and increased healthcare utilization, suggesting that patients with moderate or severe GERD should receive targeted management with the most effective treatment strategies.

This study investigated work engagement as a baseline predictor of onset of major depressive episode (MDE). The study used a prospective cohort design, conforming to the STROBE checklist. Participants were recruited from the employee population of a private think tank company (N = 4,270), and 1,058 (24.8%) of them completed a baseline survey, of whom 929 were included in this study. Work engagement and psychological distress at baseline were assessed as predictor variables. MDE was measured at baseline and at each of the follow-ups as the outcome, using the web-based, self-administered version of the Japanese WHO-CIDI 3.0 depression section based upon DSM-IV-TR/DSM-5 criteria. Cox discrete-time hazards analyses were conducted to estimate hazard ratios (95% confidence intervals CIs). Follow-up rates of participants (N = 929) were 78.4%, 67.2%, and 51.6% at 1-, 2-, and 3-year follow-ups, respectively. The association between work engagement at baseline and the onset of MDE was U-shaped. Compared with a group with low work engagement scores, groups with the middle and high scores showed significantly (HR = 0.19, 95% CI = 0.05 to 0.64; p = 0.007) and marginally significantly (HR = 0.48, 95% CI = 0.20 to 1.15, p = 0.099) lower risks of MDE, respectively, over the follow-ups, after adjusting for covariates. The pattern remained the same after additionally adjusting for psychological distress. The present study first demonstrated work engagement as an important predictor of the onset of MDE diagnosed according to an internationally standard diagnostic criteria of mental disorders.

Nuclear subs to explore Arctic?

NASA Astrophysics Data System (ADS)

The international community of scientists has become interested in the idea of using a nuclear submarine to explore the Arctic and other inaccessible regions of the World Ocean. Several alternative approaches to formulating a concept and the respective plan of action put forward by different expert groups have been amply discussed [Eos, May 12, 1992; Navy News and Undersea Technology, November 9, 1992]. The Russian Academy of Sciences has created a working group, “Science-NSM,” to coordinate efforts in working out the concept of the project and the plan of action, determine the main scientific and applied problems and criteria for selecting the type of nuclear submarine to be rebuilt, appraise the possible solutions of occurring problems, as well as to effect international contacts. Members of the group include E. P. Velikhov (chairman), vice-president of the Russian Academy of Sciences; D. M. Klimov (deputy chairman); and Y. D. Chasheckin (scientific secretary).

Population health and social governance: analyzing the mainstream incorporation of ethnography.

PubMed

O'Byrne, Patrick

2012-06-01

Recently, health care workers (researchers, academics, policy writers, clinicians) have begun to view ethnography as an acceptable research methodology for informing public health work. This corresponds with a change in public health practice toward population health, wherein identifiable groups are examined to identify the group-level and contextual factors that affect their health statuses. Although population health-based methodological and outcomes-focused examinations have already occurred regarding ethnography, no extant literature scrutinizes the incorporation of ethnography into mainstream public and population health work from a sociopolitical viewpoint. Consequently, such an investigation occurs here using Foucault's concepts of discipline and Lupton's advancement of Foucault's ideas about the imperative of health. The outcome of this investigation is the assertion that ethnography is a strategic method for disciplining populations that do not respect the imperative of health. In other words, ethnography helps generate the data that can be used to normalize large groups of people.

A mismatch between individual physical capacities and physical work demands enhance the risk for musculoskeletal disorders, poor work ability and sickness absence, termed physical deterioration. However, effective intervention strategies for preventing physical deterioration in job groups with high physical demands remains to be established. This paper describes the background, design and conceptual model of the FINALE programme, a framework for health promoting interventions at 4 Danish job groups (i.e. cleaners, health-care workers, construction workers and industrial workers) characterized by high physical work demands, musculoskeletal disorders, poor work ability and sickness absence. A novel approach of the FINALE programme is that the interventions, i.e. 3 randomized controlled trials (RCT) and 1 exploratory case-control study are tailored to the physical work demands, physical capacities and health profile of workers in each job-group. The RCT among cleaners, characterized by repetitive work tasks and musculoskeletal disorders, aims at making the cleaners less susceptible to musculoskeletal disorders by physical coordination training or cognitive behavioral theory based training (CBTr). Because health-care workers are reported to have high prevalence of overweight and heavy lifts, the aim of the RCT is long-term weight-loss by combined physical exercise training, CBTr and diet. Construction work, characterized by heavy lifting, pushing and pulling, the RCT aims at improving physical capacity and promoting musculoskeletal and cardiovascular health. At the industrial work-place characterized by repetitive work tasks, the intervention aims at reducing physical exertion and musculoskeletal disorders by combined physical exercise training, CBTr and participatory ergonomics. The overall aim of the FINALE programme is to improve the safety margin between individual resources (i.e. physical capacities, and cognitive and behavioral skills) and physical work demands, and thereby reduce the physical deterioration in a long term perspective by interventions tailored for each respective job-group. The FINALE programme has the potential to provide evidence-based knowledge of significant importance for public health policy and health promotion strategies for employees at high risk for physical deterioration.

Evaluate the effectiveness of educational interventions on hearing health developed at a hospital laundry. Quantitative assessment conducted at a hospital laundry. The study sample comprised 80 workers of both genders divided into two groups: Study Group (SG) and Control Group (CG). The educational interventions in hearing preservation were evaluated based on a theoretical approach using the Participatory Problem-based Methodology in five workshops. To assess the results of the workshops, an instrument containing 36 questions on knowledge, attitudes, and practices in hearing preservation at work was used. Questionnaires A and B were applied prior to and one month after intervention, respectively. The answers to both questionnaires were analyzed by group according to gender and schooling. Results of the pre-intervention phase showed low scores regarding knowledge about hearing health in the work setting for both groups, but significant improvement in knowledge was observed after intervention in the SG, with 77.7% of the answers presenting significant difference between the groups. There was also an improvement in the mean scores, with 35 responses (95.22%) presenting scores >4 (considered adequate). The women presented lower knowledge scores than the men; however, these differences were not observed in the SG after the workshops. Schooling was not a relevant factor in the assessment. The educational proposal grounded in the Participatory Problem-based Methodology expanded knowledge about hearing health at work among the participants.

Evaluation of the work of hospital districts' research ethics committees in Finland.

The main task of research ethics committees (RECs) is to assess research studies before their start. In this study, 24 RECs that evaluate medical research were sent questionnaires about their structure and functions. The RECs were divided into two separate groups: those working in university hospital districts (uRECs) and those in central hospital districts (non-uRECs). The two groups were different in many respects: the uRECs were bigger in size, covered a wider range of disciplines (both medical and non-medical), had better resources and more frequent and regular meetings. After the survey was performed and analysed, the Medical Research Act was amended so that only hospital districts with a medical faculty in their region had a duty to establish ethics committees. After the amendment, the number of RECs evaluating medical research in Finland decreased from 25 to 9. The ethics committees that remained had wider expertise and were better equipped already by the time of this survey. Only one non-uREC was continuing its work, and this was being done under the governance of a university hospital district. Simple measures were used for qualitative analysis of the work of RECs that evaluate medical research. These showed differences between RECs. This may be helpful in establishing an ethics committee network in a research field or administrational area. Published by the BMJ Publishing Group Limited.

Rupture of the Achilles tendon is a common injury during working years. Aggressive rehabilitation may provide better outcomes, but also a greater chance of re-rupture. To determine if aggressive rehabilitation has better clinical outcomes for Achilles tendon function, Triceps surae function, one-leg heel rise capacity and lower complication rate during twelve weeks after percutaneous Achilles tendon repair compared to conventional rehabilitation. Randomized controlled trial. Thirty-nine patients were prospectively randomized. The aggressive group (n=20, 41.4 ± 8.3 years) received rehabilitation from the first day after surgery. The conventional group (n=19, 41.7 ± 10.7 years) rested for 28 days, before rehabilitation started. The statistical parameters were the Achilles tendon rupture score (ATRS), verbal pain scale, time to return to work, pain medication consumption, Achilles tendon strength, dorsiflexion range of motion (RoM), injured-leg calf circumference, calf circumference difference, one-leg heel rise repetition and difference, re-rupture rate, strength deficit rate, and other complication rates. Mixed-ANOVA and Bonferroni's post hoc test were performed for multiple comparisons. Student's t-test was performed for parameters measured on the 12th week. The aggressive group with respect to the conventional group had a higher ATRS; lower verbal pain score; lower pain medication consumption; early return to work; higher Achilles tendon strength; higher one-leg heel rise repetitions; and lower one-leg heel rise difference. The re-rupture rate was 5% and 5%, the strength deficit rate was 42% and 5%, and other complications rate was 11% and 15% in the conventional and aggressive group, respectively. Patients with Dresden repair and aggressive rehabilitation have better clinical outcomes, Achilles tendon function and one-leg heel rise capacity without increasing the postoperative complications rate after 12 weeks compared to rehabilitation with immobilization and non-weight-bearing during the first 28 days after surgery.

To determine the effects of a low-fat plant-based diet program on anthropometric and biochemical measures in a multicenter corporate setting. Employees from 10 sites of a major US company with body mass index ≥ 25 kg/m(2) and/or previous diagnosis of type 2 diabetes were randomized to either follow a low-fat vegan diet, with weekly group support and work cafeteria options available, or make no diet changes for 18 weeks. Dietary intake, body weight, plasma lipid concentrations, blood pressure and glycated hemoglobin (HbA1C) were determined at baseline and 18 weeks. Mean body weight fell 2.9 kg and 0.06 kg in the intervention and control groups, respectively (P<0.001). Total and low-density lipoprotein (LDL) cholesterol fell 8.0 and 8.1 mg/dl in the intervention group and 0.01 and 0.9 mg/dl in the control group (P<0.01). HbA1C fell 0.6 percentage point and 0.08 percentage point in the intervention and control group, respectively (P<0.01).Among study completers, mean changes in body weight were -4.3 kg and -0.08 kg in the intervention and control groups, respectively (P<0.001). Total and LDL cholesterol fell 13.7 and 13.0 mg/dl in the intervention group and 1.3 and 1.7 mg/dl in the control group (P<0.001). HbA1C levels decreased 0.7 percentage point and 0.1 percentage point in the intervention and control group, respectively (P<0.01). An 18-week dietary intervention using a low-fat plant-based diet in a corporate setting improves body weight, plasma lipids, and, in individuals with diabetes, glycemic control.

Motor activity of boys (age 8-12 years) with (n=19) and without (n=18) ADHD was objectively measured with actigraphy across experimental conditions that varied with regard to demands on executive functions. Activity exhibited during two n-back (1-back, 2-back) working memory tasks was compared to activity during a choice-reaction time (CRT) task that placed relatively fewer demands on executive processes and during a simple reaction time (SRT) task that required mostly automatic processing with minimal executive demands. Results indicated that children in the ADHD group exhibited greater activity compared to children in the non-ADHD group. Further, both groups exhibited the greatest activity during conditions with high working memory demands, followed by the reaction time and control task conditions, respectively. The findings indicate that large-magnitude increases in motor activity are predominantly associated with increased demands on working memory, though demands on non-executive processes are sufficient to elicit small to moderate increases in motor activity as well.

During the past six months since the Second Helios Joint Working Group Meeting held 27-30 April 1970 at Goddard Space Flight Center, the TDS Sub-Group supported the Helios Project Office and the other Sub-Groups in the timely disposition of action items and the dissemination of information pertinent to the development of interface documentation. Of particular importance during this time period was the Project's decision to incorporate a single-channel telemetry system design aboard the spacecraft. The TDS Sub-Group participated actively in the process that led to this decision. Still under active study with TDS participation is the pending Project Office decision regarding the incorporation of a ranging capability within the telecommunications design. The TDS Sub-Group assisted the Mission Analysis and Operations Sub-Group in establishment of a study effort concerning the Near-Earth Sequence of Events from launch to launch plus 8 hours. This study, which will provide valuable data for the spacecraft telecommunications design, will include participation by the Experiment, Launch Vehicle, Spacecraft, as well as the TDS and MA&O Sub-Groups. Also during the past 6-month period, the TDS, in conjunction with the Spacecraft Sub-Group, initiated activity to develop the Helios Spacecraft/TDS Compatibility Test Plans and Procedures. Activity concerning the foregoing interface discussions has been and will continue to be based upon the "TDS Estimated Capabilities Document for the Helios Missions" (613-1), and the "DSN/Flight Project Interface Design Handbook" (810-5). These will continue to be considered TDS controlling documents until specific Helios Project/TDS interface documentation is generated and signed off by the respective parties. In addition to the above, the DSN continued the Helios Trainee Program with seven GfW/DFVLR trainees in residence at JPL. Two trainees will complete their year's residency concurrent with the Third Helios Joint Working Group Meeting, while four new trainees are expected to arrive following the Third Helios Joint Working Group Meeting. These and other activities are reported in detail in the paragraphs that follow.

2016-01-01

Objectives: This study aimed to identify the practical abilities required by nonspecialist occupational physicians and specify the priorities for training programs. Methods: A practical abilities list was developed through a focus group meeting of specialists. We created a survey questionnaire and asked three groups, namely, occupational physicians, occupational health nurses, and health officers, to rate the importance of each practical ability. Results: The mean scores for all 45 items were greater than 4, i.e., in the middle of the 7-point Likert scale, for all the three groups. The occupational physicians' responses had a correlation with the other groups' responses. However, there were differences with regard to some practical abilities between the three groups. Five practical abilities from the top quartile were marked "A" by all the three groups: "Submit opinions on fitness for duty and work accommodation on the basis of data from health examination," "Respect employee privacy," "Submit opinion on fitness for duty and work accommodation on the basis of data from face-to-face interviews with employees," "Submit opinions on fitness for duty and work accommodation on the basis of data from health surveillance," and "Implement face-to-face interviews for employees who have worked overtime and evaluate the subjects' conditions including mental and physical health status, degree of accumulated fatigue, and depression." Conclusions: This study resulted in a rank-ordered list of 45 practical abilities that are required by nonspecialist occupational physicians. This result may be useful to review and redesign the existing training program for nonspecialist occupational physicians. PMID:27108644

Even when euthymic bipolar disorder patients can have persistent deficits in working memory, but the neural basis of this deficit remains unclear. We undertook an functional magnetic resonance imaging investigation of euthymic bipolar disorder patients performing two working memory paradigms; the two-back and Sternberg tasks, selected to examine the central executive and the phonological loop respectively. We hypothesized that neuronal dysfunction would be specific to the network underlying the executive rather than the phonological loop component of working memory. Twelve right-handed euthymic bipolar I males receiving lithium carbonate monotherapy were matched with 12 controls. The two-back task comprised a single working memory load contrasted with baseline vigilance condition. The Sternberg paradigm used a parametric design incorporating variable working memory load with fixed delay between presentation of an array of items to be remembered and a target item. Functional activation data were acquired during performance of the tasks and were analysed to produce brain activation maps representing significant group differences in activation (ANOVA). Load-response curves were derived from the Sternberg task data set. There were no significant between-group differences (t-test) in performance of the two-back task, or in 2 x 5 group by memory load ANOVA for the performance data from Sternberg task. In the two-back task, compared with controls bipolar disorder patients showed reductions in bilateral frontal, temporal and parietal activation, and increased activations with the left precentral, right medial frontal and left supramarginal gyri. No between-group differences were observed in the Sternberg task at any working memory load. Our findings support the notion that, in euthymic bipolar disorder, failure to engage fronto-executive function underpins the core neuropsychological deficits. Blackwell Munksgaard, 2004

Cerebrovascular accident is a focal neurological deficiency occurring suddenly and lasting for more than 24 hours. The purpose of our work is to determine the role of the functional electrical simulation (FES) in the rehabilitation of patients with hemiparesis, which occurred as a consequence of a cerebrovascular accident. This study includes the analysis of two groups of 40 patients with hemiparesis (20 patients with deep hemiparesis and 20 patients with light hemi- paresis), a control group which was only treated with kinesiotherapy and a tested group which was treated with kinesiotherapy and functional electrical stimulation. Both groups of patients were analyzed in respect to their sex and age. Additional analysis of the walking function was completed in accordance with the BI and RAP index. The analysis of the basic demographical data demonstrated that there is no significant difference between the control and tested group. The patients of both groups are equal in respect of age and sex. After 4 weeks of rehabilitation of patients with deep and light hemiparesis there were no statistically significant differences between the groups after evaluation by the BI index. However, a statistically significant difference was noted between the groups by the RAP index among patients with deep hemiparesis. After 8 weeks of rehabilitation the group of patients who were treated with kinesiotherapy and functional electrical stimulation showed better statistically significant results of rehabilitation in respect to the control group with both the BI index and the RAP index (p<0,001). In conclusion, we can state that the patients in rehabilitation after a cerebrovascular accident require rehabilitation longer than 4 weeks. Walking rehabilitation after stroke is faster and more successful if we used functional electrical stimulation, in combination with kinesiotherapy, in patients with disabled extremities.

Here we analyze gray matter indices before and after completing a challenging adaptive cognitive training program based on the n-back task. The considered gray matter indices were cortical thickness (CT) and cortical surface area (CSA). Twenty-eight young women (age range 17–22 years) completed 24 training sessions over the course of 3 months (12 weeks, 24 sessions), showing expected performance improvements. CT and CSA values for the training group were compared with those of a matched control group. Statistical analyses were computed using a ROI framework defined by brain areas distinguished by their genetic underpinning. The interaction between group and time was analyzed. Middle temporal, ventral frontal, inferior parietal cortices, and pars opercularis were the regions where the training group showed conservation of gray matter with respect to the control group. These regions support working memory, resistance to interference, and inhibition. Furthermore, an interaction with baseline intelligence differences showed that the expected decreasing trend at the biological level for individuals showing relatively low intelligence levels at baseline was attenuated by the completed training.

Background: The impact of the European Working Time Directive and subsequent collective wage agreements for doctors from 2006 onwards were substantial. So far, no systematic evaluation of their application in Germany has been performed. We evaluated the impact four years after implementation of new shift models in a University Hospital for Gynaecology and Obstetrics (UHGO). Methods: A new shift model was created together with doctors of Tübingen UHOG in 2007 and implemented in 2008. Documentation of working hours has hence been done electronically. Adherence to the average weekly working time limit (AWTL) and the maximum of 10 h daily working time (10 h-dwt) was evaluated, as well as staffing costs in relation to case-weight points gathered within the German DRG (diagnosis related groups) System. Results: Staff increased from a mean of 44.7 full time equivalent (FTE) doctors in 2007 to 52.5 FTE in 2009, 50.8 in 2010, and 54.5 in 2011. There was no statistically significant difference of the monthly staff expenditures per case-weight between the years 2009 or 2010 vs. 2007. 2011, however, was significantly more expensive than 2007 (p = 0.02). The internal control group (five other departments of the university hospital) did not show an increase during the same period. AWTL were respected by 90, 96, and 98 % in 2009, 2010, and 2011, respectively. Of all shifts 10 h-dwt was exceeded by 7.4 % in 2009, 1.3 % in 2010, and 2.6 % in 2011, with significant differences between 2009 and both, 2010 and 2011 (p < 0.001), and between 2010 and 2011 (p = 0.02). Discussion: AWTL and 10 h-dwt could be continuously respected quite well after implementation of the new shift model without increasing the cost/earnings ratio for the first two years. However, in 2011 the ratio increased significantly (p = 0.02).

The aim of this study was to examine working memory (WM) modalities (visual-spatial and auditory-verbal) and processes (maintenance and manipulation) in children with and without attention-deficit/hyperactivity disorder (ADHD). The sample consisted of 63 8-year-old children with ADHD and an age- and sex-matched non-ADHD comparison group (N=51). Auditory-verbal and visual-spatial WM were assessed using the Digit Span and Spatial Span subtests from the Wechsler Intelligence Scale for Children Integrated - Fourth Edition. WM maintenance and manipulation were assessed via forward and backward span indices, respectively. Data were analyzed using a 3-way Group (ADHD vs. non-ADHD)×Modality (Auditory-Verbal vs. Visual-Spatial)×Condition (Forward vs. Backward) Analysis of Variance (ANOVA). Secondary analyses examined differences between Combined and Predominantly Inattentive ADHD presentations. Significant Group×Condition (p=.02) and Group×Modality (p=.03) interactions indicated differentially poorer performance by those with ADHD on backward relative to forward and visual-spatial relative to auditory-verbal tasks, respectively. The 3-way interaction was not significant. Analyses targeting ADHD presentations yielded a significant Group×Condition interaction (p=.009) such that children with ADHD-Predominantly Inattentive Presentation performed differentially poorer on backward relative to forward tasks compared to the children with ADHD-Combined Presentation. Findings indicate a specific pattern of WM weaknesses (i.e., WM manipulation and visual-spatial tasks) for children with ADHD. Furthermore, differential patterns of WM performance were found for children with ADHD-Predominantly Inattentive versus Combined Presentations. (JINS, 2016, 22, 1-11).

Integration of workplace employee health promotion (HP) and occupational health and safety (OHS) work into organizational quality improvement systems is suggested as a way to strengthen HP and OHS activities in an organization. The aim of this article was to study what consequences integration of HP, OHS and a quality improvement system called kaizen has on the frequency and type of HP and OHS activities. A quasi-experimental study design was used where an integration of the three systems for HP, OHS respectively kaizen, was performed at six intervention units at a Swedish hospital. The remaining six units served as controls. Document analysis of all employees' written improvement suggestions (kaizen notes) during 2013 was conducted. The findings show that the intervention group had more suggestions concerning HP and OHS (n = 114) when compared with the control group (n = 78) and a greater variety of HP and OHS suggestions. In addition, only the intervention group had included HP aspects. In both groups, most kaizen notes with health consideration had a preventive focus rather than rehabilitative. The intervention, i.e. the integration of HP, OHS and kaizen work, had a favourable effect on HP and OHS work when compared with the controls. The results of the study support that this system can work in practice at hospitals. © The Author 2015. Published by Oxford University Press. All rights reserved.

[Physical work capacity in coal miners and industrial workers].

Benavides, R

1992-10-01

The aerobic work capacity of 220 coal miners aged 22 to 63 years with a high physical work load and 78 industrial workers aged 19 to 58 years with a relatively light work load was measured to observe if there was a relationship between the work load of these subjects and their aerobic work capacity. All the subjects were subjected to a medical examination, spirometry, chest x Rays and anthropometric measurements. Aerobic work capacity was indirectly estimated extrapolating pulse rates obtained al submaximal work loads in a bicycle ergometer to the calculated maximal cardiac frequency for age. Aerobic work capacity was not different between coal miners and industrial workers, either measured as absolute values (2.43 +/- 0.41 and 2.5 +/- 0.49 l/min respectively) or as relative values (43.2 +/- 6.9 and 43.4 +/- 8.2 ml/kg lean body mass respectively). These values decreased with age in the same proportion in both groups (0.24 l/min per decade). Lean body mass was significantly higher in industrial workers and decreased significantly with age only in coal miners. Considering published energy requirements for mine labors, none of the studied miners should work as digger and a high proportion of the other workers would be exposed to hazardous work loads to their health. The fact that over 50% of these subjects can efficiently fulfill their jobs may indicate that they have a high anaerobic work capacity. This hypothesis needs confirmation with future studies.

Many research works have explored the use of the low power laser as a tool for the control of inflammatory processes. The anti-inflammatory effect of low power optical radiation and its ability to induce analgesia has been reported for different experimental conditions. Many published works are very qualitative in nature. In this work the action of low power laser radiation on acute inflammatory process is evaluated. The time evolution of rat paw edema and pain induced by carrageenan was experimentally monitored. A 632.8 nm He-Ne laser was used for the treatment. The laser treatment, at a dosage of 2,5 J/cm2, was applied at the first, second and third hour after the induction of the inflammation. A hydroplethysmometer was used for the evaluation of the inflammation. The measurement of pain sensitivity was performed according to the method described by Randall and Selito, (1957). The laser treatment was capable of inhibiting the carrageenan-induced hyperalgesia by 49% (p<0,001) at the second hour after the induction, as compared to the non-treated group. At the fourth hour (peak of the carrageenan action on hyperalgesia) and at the sixth hour, the achieved inhibition was 49% (p<0,001) and 61% (p<0,001), respectively. In the treated groups, the edema evolution was inhibited by 38% (p<0,01), at the second hour after induction, as compared to the non-treated groups. At the fourth hour (peak of the carrageenan action on leakage) and at sixth hour the achieved inhibition was 35% (p<0,01) and 30% (p<0,05) respectively.

Although the prevalence of work-related stress has increased, knowledge on the contributions of that stress to long-term adverse health effects is still lacking. Stress biomarkers can reveal early signs of negative health effects, but no previous studies have measured both acute stress reactions and long-term exposure to job strain using both salivary cortisol and α-amylase (AA). The present study examines the association between job strain and these biomarkers among shift-working female health care professionals in the laboratory and the field. The 95 participants were recruited from hospital wards categorized in either the top (high job strain [HJS] group, n = 42) or the bottom quartile of job strain (low job strain [LJS] group, n = 53), as rated by survey responses. Participants' self-perceived job strain was at least as high or low as the ward's average estimation. Saliva samples were collected during the Trier Social Stress Test (TSST), preselected morning and night shifts, and a day off. There was a larger increase in the cortisol concentration of participants in the HJS than in the LJS group (2.27- vs. 1.48-fold, respectively, nonsignificant) during the TSST. Participants in the HJS group also had higher salivary AA levels 30 min after awakening on the morning-shift day than those in the LJS group (p = .02), whereas the salivary cortisol awakening response on the day off was higher in the LJS group (p = .05, education as a covariate). The remaining stress-biomarker results did not differ significantly between groups. These data suggest that HJS in shift-working health care professionals is weakly associated with changes in stress biomarkers. © The Author(s) 2015.

Emerging evidence indicates that repetitive head impacts, even at a sub-concussive level, may result in exacerbated or prolonged neurological deficits in athletes. This study aimed to: 1) quantify the effect of repetitive head impacts on the alteration of neuronal activity based on functional magnetic resonance imaging (fMRI) of working memory after a high school football season; and 2) determine whether a neck collar that applies mild jugular vein compression designed to reduce brain energy absorption in head impact through "slosh" mitigation can ameliorate the altered fMRI activation during a working memory task. Participants were recruited from local high school football teams with 27 and 25 athletes assigned to the non-collar and collar group, respectively. A standard N-Back task was used to engage working memory in the fMRI at both pre- and post-season. The two study groups experienced similar head impact frequency and magnitude during the season (all p > 0.05). fMRI blood oxygen level dependent (BOLD) signal response (a reflection of the neuronal activity level) during the working memory task increased significantly from pre- to post-season in the non-collar group (corrected p < 0.05), but not in the collar group. Areas displaying less activation change in the collar group (corrected p < 0.05) included the precuneus, inferior parietal cortex, and dorsal lateral prefrontal cortex. Additionally, BOLD response in the non-collar group increased significantly in direct association with the total number of impacts and total g-force (p < 0.05). Our data provide initial neuroimaging evidence for the effect of repetitive head impacts on the working memory related brain activity, as well as a potential protective effect that resulted from the use of the purported brain slosh reducing neck collar in contact sports.

Employees with a chronic physical condition may be hampered in job performance due to physical or cognitive limitations, pain, fatigue, psychosocial barriers, or because medical treatment interferes with work. This study investigates the effect of a group-training program aimed at job maintenance. Essential elements of the program are exploration of work-related problems, communication at the workplace, and the development and implementation of solutions. Participants with chronic physical diseases were randomly assigned to the intervention (N=64) or the control group (N=58). Participants were eligible for the study if they had a chronic physical disease, paid employment, experienced work-related problems, and were not on long-term 100% sick leave. Primary outcome measures were self-efficacy in solving work- and disease-related problems (14-70), job dissatisfaction (0-100), fatigue (20-140) and job maintenance measured at 4-, 8-, 12- and 24-month follow-up. We used GLM repeated measures for the analysis. After 24 months, loss to follow-up was 5.7% (7/122). Self-efficacy increased and fatigue decreased significantly more in the experimental than the control group [10 versus 4 points (P=0.000) and 19 versus 8 points (P=0.032), respectively]. Job satisfaction increased more in the experimental group but not significantly [6 versus 0 points (P=0.698)]. Job maintenance was 87% in the experimental and 91% in the control group, which was not a significant difference. Many participants in the control group also undertook actions to solve work-related problems. Empowerment training increases self-efficacy and helps to reduce fatigue complaints, which in the long term could lead to more job maintenance. Better understanding of ways to deal with work-related problems is needed to develop more efficient support for employees with a chronic disease.

To study the magnetic resonance imaging (MRI) in the wrist joint of coal miners who work in excavation and vibration department. Forty-three coal miners with the hand-arm vibration disease served as the observation group while 20 workers who were not working in the vibration department acted as the control group. The patients in the observation group were divided into five subgroups according to the time when they received vibration. The regularity of the development of signs and symptoms of MRI was observed and analyzed. The hydroarthrosis was most found in MRI. There were significant difference in hydroarthrosis (chi(2) = 8.80, P < 0.01), osteoporosis and osteomyelitis (chi(2) = 3.91, chi(2) = 5.01, P < 0.05 respectively) between the observation group and the control group. The edema of bone marrow and the avascular necrosis of ossa carpi were found only in the observation group and not found in the control group. The hydroarthrosis and the edema of bone marrow occurred most in the early stage of vibration. The signal in the edema of the bone marrow of the distal end of the radius was decreased in the GE sequence T(2)WI with the specificity. (1) Changes in the wrist joint occur in the early stage of the vibration work, and can be found in the MRI. (2) The edema of the bone marrow of the distal end of the radius is of great value in the diagnosis of the hand-arm vibration disease.

A device for dynamic acquisition and distribution analysis of in-socket pressure for patients with partial foot amputation is presented in this work. By using the developed system, we measured and generated pressure distribution graphs, obtained maximal pressure, and calculated pressure-time integral (PTI) of three subjects with partial foot amputation and of a group of Healthy subjects (Hs) (n = 10). Average maximal pressure in the healthy group was 19.4 ± 4.11 PSI, while for the three amputated patients, this was 27.8 ± 1.38, 17.6 ± 1.15, 29.10 ± 3.9 PSI, respectively. Maximal pressure-time integral for healthy subjects was 11.56 ± 2.83 PSI*s, and for study subjects was 19.54 ± 1.9, 12.35 ± 1.48, and 13.17 ± 1.31 PSI*s, respectively. The results of the control group agree with those previously reported in the literature. The pressure distribution pattern showed clear differences between study subjects and those of the control group; these graphs allowed us to identify the pressure in regions-of-interest that could be critical, such as surgical scars. The system presented in this work will aid to assess the effectiveness with which prosthetic systems distribute load, given that the formation of ulcers is highly linked to the pressure exercised at the point of contact; in addition, these results will help to investigate the comfort perception of the prosthesis, a factor directly influenced by the stump's pressure distribution.

Case managers within injury compensation systems are confronted with various emotional demands. Employing the concept of emotional labour, this paper explores distinctive aspects of these demands. The findings are drawn from focus groups with 21 Australian case managers. Case managers work was characterised by extra-role commitments, emotional control, stress and balancing tensions arising from differing stakeholder expectations about outcomes related to compensation and return to work. By examining the experiences of case managers, the findings add to the literature on the emotional labour of front line service workers, especially with respect to the demands involved in managing the conflicting demands of work.

The relation between irregular and inconvenient working hours and the outcome of pregnancy was studied among women employed at a hospital in Sweden some time between 1980 and 1984. A questionnaire was distributed to 807 women; 81% replied. The pregnancies were divided into six groups with respect to work schedules during pregnancy. A slightly, but not significantly, increased risk of miscarriage was found in women who worked irregular hours or rotating shifts compared with women who worked only during the day (RR = 1.44, 95% confidence interval 0.83-2.51). Infants of non-smoking mothers who worked irregular hours had significantly lower birth weights than infants of non-smoking women working day time only. This difference was largest at birth order 2+. Similar results were found for infants of this birth order whose non-smoking mothers worked evenings or rotating shift.

Transoral endoscopic thyroidectomy vestibular approach (TOETVA) provides excellent cosmetic results from its potential for scar-free operation. The procedure has been applied successfully for Graves' disease by the authors of this work and compared with the standard open cervical approach to evaluate its safety and outcomes. From January 2014 to November 2016, a total of 97 patients with Graves' disease were reviewed retrospectively. Open thyroidectomy (OT) and TOETVA were performed in 49 patients and 46 patients, respectively. For TOETVA, a three-port technique through the oral vestibule was utilized. The thyroidectomy was done endoscopically using conventional laparoscopic instruments and an ultrasonic device. Patient demographics and surgical variables, including operative time, blood loss, and complications, were investigated and compared. TOETVA was performed successfully in all 45 patients, although conversion to open surgery was deemed necessary in one patient. All patient characteristics for both groups were similar. Operative time was shorter for the OT group compared to the TOETVA group, which totaled 101.97±24.618 and 134.11±31.48 minutes, respectively (P<0.5). Blood loss was comparable for both groups. The visual analog scale (VAS) pain score for the TOETVA group was significantly lower than for the OT group on day 1 (2.08±1.53 vs . 4.57±1.35), day 2 (0.84±1.12 vs . 2.57±1.08) and day 3 (0.33±0.71 vs . 1.08±1.01) (P<0.05). Transient recurrent laryngeal nerve (RLN) palsy was found in four and two cases of TOETVA and OT group, respectively. Transient hypocalcemia was found in ten and seven cases of TOETVA and OT group, respectively. No other complications were observed. TOETVA is a feasible and safe treatment for Graves' disease in comparison to the standard open cervical approach. It is considered a viable alternative for patients who have been indicated for surgery with excellent cosmetic results.

The profound impact of empathy training on quality nursing care has been recognized. Studies have shown that there has been little improvement in nurses' communication skills, and that they should work to enhance this area. Relevant training will lead to an improvement in nurses' empathic skills, which in turn, will enable them to understand their patients better, establish positive interpersonal relationships with them, and boost their professional satisfaction. To reveal the effect of empathy training on the empathic skills of nurses. This study was conducted as an experimental design. The research sample consisted of 48 nurses working at the pediatric clinics of Farabi hospital of Karadeniz Technical University in Turkey (N = 83). Two groups, an experimental group (group 1) and a control group (group 2) were determined after questionnaires were supplied to all nurses in the study sample. At first, it was intended to select these groups using a random method. However, since this may have meant that the experimental and control groups were formed from nurses working in the same service, the two groups were selected from different services to avoid possible interaction between them. The nurses in the Group 1 were provided with empathy training through group and creative drama techniques. Pre-tests and post-tests were conducted on both groups. Data was collected via a questionnaire designed around the topic "empathic skill scale-ESS", developed by Dokmen. The Kolmogorov Smirnov test was employed to assess whether the measurable data was suitable for normal distribution. Data was presented as numbers and percentage distributions, as mean ± standard deviation and Chi-square, and as student t tests and paired t tests. The level of significance was accepted as P < 0.05. The nurses in the experimental group had a mean score of 146.7 ± 38.8 and 169.5 ± 22.1 in the ESS pre-test and post-test, respectively. Although the nurses in the control group had a pre-test mean score of 133.7 ± 37.1, which increased to 135.1 ± 51.7 after the training, no statistically significant difference was found (P = 0.886). A comparison of the groups indicated that they scored similarly in the pre-test. However, the experimental group scored significantly higher than the control group in the post-test (P = 0.270 and P = 0.015, respectively). In the light of these findings, it is recommended that communication skills should be widely included in in-service training programs; similar studies should be conducted on broader control groups formed through randomization; and a comparison should be made between the findings.

However, since this may have meant that the experimental and control groups were formed from nurses working in the same service, the two groups were selected from different services to avoid possible interaction between them. The nurses in the Group 1 were provided with empathy training through group and creative drama techniques. Pre-tests and post-tests were conducted on both groups. Data was collected via a questionnaire designed around the topic “empathic skill scale-ESS”, developed by Dokmen. The Kolmogorov Smirnov test was employed to assess whether the measurable data was suitable for normal distribution. Data was presented as numbers and percentage distributions, as mean ± standard deviation and Chi-square, and as student t tests and paired t tests. The level of significance was accepted as P < 0.05. Results The nurses in the experimental group had a mean score of 146.7 ± 38.8 and 169.5 ± 22.1 in the ESS pre-test and post-test, respectively. Although the nurses in the control group had a pre-test mean score of 133.7 ± 37.1, which increased to 135.1 ± 51.7 after the training, no statistically significant difference was found (P = 0.886). A comparison of the groups indicated that they scored similarly in the pre-test. However, the experimental group scored significantly higher than the control group in the post-test (P = 0.270 and P = 0.015, respectively). Conclusions In the light of these findings, it is recommended that communication skills should be widely included in in-service training programs; similar studies should be conducted on broader control groups formed through randomization; and a comparison should be made between the findings.

Background Radar transmitters emit high-power radiofrequency radiation by creation of a high-voltage and high-frequency alternating electrical current. Methods: Health effects of occupational exposure to military radar were investigated. Visual reaction time was recorded with a simple blind computer-assisted-visual reaction time test. To assess the short-term memory, modified Wechsler Memory Scale test was performed. Results: The mean +/- SD reaction time in radar works (N=100) and the control group (N=57) were 238.58 +/− 23.47 milliseconds and 291.86 +/− 28.26 milliseconds (P<0.0001), respectively. The scores of forward digit span in radar works and the control group were 3.56 +/− 0.77 and 4.29 +/− 1.06 (P<0.0001), while the scores of backward digit span in radar works and the control group were 2.70 +/− 0.69 and 3.62 +/− 0.95 (P<0.0001). The scores of word recognition in radar works and the control group were 3.37 +/− 1.13 and 5.86 +/− 1.11 (P<0.0001). Finally, the scores of paired words in radar works and the control group were 13.56 +/− 1.78 and 15.21 +/− 2.20 (P<0.0001). It can be concluded that occupational exposures to radar radiations decreases reaction time, which may lead to a better response to different hazards. Conclusion: To the best of our knowledge, this is the first study to show that occupational exposure to radar microwave radiation leads to decreased reaction time and the lower performance of short-term memory. Altogether, these results indicate that occupational exposure to radar microwave radiations may be linked to some non-detrimental and detrimental health effects. PMID:23785684

Petroleum refinery workers' exposure to the carcinogens benzene and 1,3-butadiene has decreased during normal operations. However, certain occupational groups or events at the refineries still involve a risk of higher exposures. The aim of this study was to examine the personal exposure to benzene and 1,3-butadiene at refinery turnarounds and during work in the oil harbour. Personal exposure measurements of benzene and 1,3-butadiene were taken during work shifts, with a priori assumed higher benzene exposure, using PerkinElmer diffusive samplers filled with Carbopack X. Mean exposure levels were calculated, and repeated exposure measurements, when available, were assessed using mixed effect models. Group and individual compliance with the Swedish occupational exposure limit (OEL) was tested for the different exposure groups. Mean benzene exposure levels for refinery workers during the three measured turnarounds were 150, 610 and 960 µg/m 3 , and mean exposures for oil harbour workers and sewage tanker drivers were 310 and 360 µg/m 3 , respectively. Higher exposures were associated with handling benzene-rich products. Most occupational groups did not comply with the Swedish OEL for benzene nor did the individuals within the groups. The exposure to 1,3-butadiene was very low, between <1 and 3 % of the Swedish OEL. Work within the petroleum refinery industry, with potential exposure to open product streams containing higher fractions of benzene, pose a risk of personal benzene exposures exceeding the OEL. Refinery workers performing these work tasks frequently, such as contractors, sewage tanker drivers and oil harbour workers, need to be identified and protected.

In both a laboratory experiment (in Australia) using university as the basis of group membership, and a scenario experiment (in India) using religion as the basis of group membership, we observe more favourable respect and fairness ratings in response to an in-group authority than an out-group authority who administers non-instrumental voice. Moreover, we observe in our second experiment that reported likelihood of protest (herein called "social-change voice") was relatively high following non-instrumental voice from an out-group authority, but relatively low following non-instrumental voice from an in-group authority. Our findings are consistent with relational models of procedural justice, and extend the work by examining likely use of alternative forms of voice as well as highlighting the relative importance of instrumentality. ©2012 The British Psychological Society.

Health-related lifestyle, harassment at work, and self-assessed health of female flight attendants in comparison to that of female nurses and female primary school teachers were surveyed. A higher proportion of flight attendants than nurses or teachers were smokers, 26% vs. 15% and 17% respectively; and consumed alcohol at least once a week, 40% vs. 21% and 16%. Repeated sexual harassment at work was more common among the flight attendants, 31% vs. 8% and 4%; whereas bullying, physical violence and threats were less prevalent among the flight attendants (12%) than among nurses (19%). Flight attendants were on average somewhat taller, but weighed on average less, 63.8 kg vs. 72.4 kg and 72.7 kg respectively. Repeated exposure to sexual harassment, bullying, violence and threats was related to less physical and psychological well-being in all the groups. Teachers scored on average significantly lower than did the flight attendants on general health and physical well-being, while nurses did not.

Evaluate patients with breast cancer undergoing chemotherapy with respect to their epidemiologic and clinical variables as well as performance at work or at home. this was a cross-sectional study including 52 women interviewed during breast cancer chemotherapy, stratified in two groups: those who continued to work and do household tasks, and did not continue to work or do household tasks. Patients were from two public hospitals in the State of São Paulo, one in Santo Andre and the other in São Bernardo do Campo. The WPAI - GH (Work Productivity and Activity Impairment) questionnaire was used to evaluate work and household performance of professionals or housewives, respectively. Mean age of the patients was 55.7 (SD=13.8), most were Caucasian (88.5%), married (55.8%), employed (65.3%) and the majority had to stop working because of treatment (51.0%), at more advanced stage (p<0.05), fatigue and nausea (p<0.05). Mean WPAI - GH was 67.04 (|SD = 5.62) for patients who stopped working and 49.17 (SD = 6.89) for those who continued to work (Mann-Whitney U test: p = 0.04). Chemotherapy leads to a decrease in performance of a sizable fraction of women with breast cancer undergoing chemotherapy. A more advanced stage of neoplasia was positively associated with withdrawal from these activities probably due to side effects such as fatigue and nausea.

To evaluate the effect of the clinical nursing path integrated with the holistic nursing on advanced schistosomiasis patients with ascites. A total of 226 advanced schistosomiasis patients with ascites were randomly divided into a control group and an experimental group (113 cases each group). The subjects in the experimental group were nursed by the clinical nursing path integrated with the holistic nursing, while those in the control group were nursed only by the holistic nursing. Then the clinical relevant indexes of the two groups were observed, and the quality of life of the patients before and after hospital discharge was assessed. The improvement rate, satisfaction degree, and awareness rate of health knowledge of the patients in the experiment group were 93.8%, 100% and 97.4%, respectively, which were significantly higher than those of the control group (all P < 0.05). The mortality rate and the complication rate of the patients in the experimental group were 0 and 2.7%, respectively, which were significantly lower than those of the control group (both P < 0.05). In addition, the average hospitalization days and the hospitalization cost of the experiment group were (12.2 ± 0.7) d and (4 725.0 ± 310.1) Yuan respectively, which were less than those of the control group (both P < 0.01). When 6 months after the discharge from hospital, the quality of life of the patients in the experimental group in various fields was significantly better than that of the control group (all P < 0.05). The clinical nursing pathway integrated with holistic nursing can effectively improve the improvement rate and decrease the mortality of the advanced schistosomiasis patients with ascites; meanwhile, it can shorten the hospitalization time and save the hospitalization cost. Therefore, this nursing model is suitable for popularization and application in the treatment and nursing work of the advanced schistosomiasis assistance.

The group theoretical methods worked out by Bargmann, Mackey and Wigner, which deductively establish the Quantum Theory of a free particle for which Galileian transformations form a symmetry group, are extended to the case of an interacting particle. In doing so, the obstacles caused by loss of symmetry are overcome. In this approach, specific forms of the wave equation of an interacting particle, including the equation derived from the minimal coupling principle, are implied by particular first-order invariance properties that characterize the interaction with respect to specific subgroups of Galileian transformations; moreover, the possibility of yet unknown forms of the wave equation is left open.

The Ellman group has been one of the most influential in the development and widespread adoption of combinatorial chemistry techniques for biomedical research. Their work has included substantial methodological development for library synthesis with a particular focus on new scaffolds rationally targeted to biomolecules of interest and biologically relevant natural products. Herein we analyze a representative set of libraries from this group with respect to their biological and biomedical relevance in comparison to existing drugs and probe compounds. This analysis reveals that the Ellman group has not only provided new methodologies to the community but also provided libraries with unique potential for further biological study. PMID:18343129

Respectable Gentlemen and Street-Savvy Men: HIV Vulnerability in Sri Lanka.

In this article, I investigate how particular discourses surrounding class specific understandings of sexual behavior and female morality shape awareness and views of the disease and personal vulnerability. Although both groups belong to the working class, those employed by the transportation board consider themselves government servants and, therefore, "respectable gentlemen." Construction workers identify easily with their class position, recognizing and sometimes trying to live up to the stereotypes of free sexuality. These different perceptions directly affect their concern and awareness of risk factors for sexually transmissible infections and safe-sex practices. While the "respectable gentlemen" consider themselves invulnerable, the "street-savvy men" learned about risks and took precautions to prevent STIs.

The classic non-working (NW) heterotopic heart transplant (HTX) model in rodents had been widely used for researches related to immunology, graft rejection, evaluation of immunosuppressive therapies and organ preservation. But unloaded models are considered not suitable for some researches. Accordingly, We have constructed a volume-loaded (VL) model by a new and simple technique. Thirty male New Zealand White rabbits were randomly divided into two groups, group NW with 14 rabbits and group VL with 16 rabbits, which served as donors and recipients. We created a large and nonrestrictive shunt to provide left heart a sufficient preload. The donor superior vena cave and ascending aorta (AO) were anastomosed to the recipient abdominal aorta (AAO) and inferior vena cava (IVC), respectively. No animals suffered from paralysis, pneumonia and lethal bleeding. Recipients' mortality and morbidity were 6.7% (1/15) and 13.3% (2/15), respectively. The cold ischemia time in group VL is slight longer than that in group NW. The maximal aortic velocity (MAV) of donor heart was approximately equivalent to half that of native heart in group VL. Moreover, the similar result was achieved in the parameter of late diastolic mitral inflow velocity between donor heart and native heart in group VL. The echocardiography (ECHO) showed a bidirectional flow in donor SVC of VL model, inflow during diastole and outflow during systole. PET-CT imaging showed the standard uptake value (SUV) of allograft was equal to that of native heart in both groups on the postoperative day 3. We have developed a new VL model in rabbits, which imitates a native heart hemodynamically while only requiring a minor additional procedure. Surgical technique is simple compared with currently used HTX models. We also developed a standard operating procedure that significantly improved graft and recipient survival rate. This study may be useful for investigations in transplantation in which a working model is required.

To investigate efficacy of early and long term physical training (PT) of moderate intensity in conditions of practical health care in Russia in patients with ischemic heart disease (IHD) of able to work age - survivors of acute coronary events. Three hundred ninety two patients were enrolled in this study. They were randomized into intervention group " O" (n=197) and control group " C" (n=195). Inclusion period was 3- 8 weeks from onset of myocardial infarction (MI), unstable angina (UA), or intervention on coronary arteries. Patients were followed up for 1 year and efficacy of intervention was assessed by results of laboratory (levels of lipids), instrumental (ECG, exercise test on veloergometer, echocardiography), and clinical examination. In the group " O" regimen of PT with work loads of moderate intensity (50-60% of power achieved during exercise test) was used. Duration of FT was 45 - 60 min, frequency - 3 times a week. All patients received standard therapy for IHD and a lipid lowering drug when indicated. Proofs of efficacy of PT in the given contingent of patients were obtained. This was manifested by significant increase of physical working capacity: prolongation of exercise time (+31.7%, p<0.001), increases of volume of work performed (+74.3%, p<0.001) and efficiency of cardiac work according to results of exercise tests. All parameters were significantly different from those in the group " C" . Structural functional parameters of the heart also improved in the group " O" : left ventricular (LV) stroke volume increased 4.5% (p<0.005), ejection fraction increased 7.2% (p<0.001), diastolic LV volume decreased 2.5% (p<0.05), systolic LV volume decreased 8.1% (p<0.001). In the group " C" stroke volume and LV ejection fraction rose to a lesser degree - by 5.5% (p<0.01) and 2.9% (p<0.05), respectively. Differences between groups in dynamics of these parameters turned out to be significant (p<0.05). Moreover in group " C" LV diastolic volume increased 2.3% (p<0.05) and systolic volume did not change, while left atrium increased 3.4% (p<0.002). At intergroup comparison differences in dynamics of these parameters were significant (p<0.005). Analysis of lipid profile after 1 year showed no changes in patients of group " C" , while in group " O" it revealed significant (3.6%) lowering of total (T) cholesterol (CH) (p<0.05 compared with baseline and change in group " C" ) and elevation of high density lipoprotein (HDL) CH (+12.3%, p<0.001; compared with group " C" p<0.005). Atherogeneity index TCH/HDLCH decreased 8.5% in the group " O" (p<0.01), and increased 12% (p<0.02) in the group " C" , difference between groups was statistically significant (p<0.001). In the group " O" body mass index decreased 2.8% (p<0.001), and frequency of attacks of angina decreased 50.8% (p<0.001; compared with group " C" p<0.001). Statistically significant differences were registered between the following parameters of composite end point and surrogate points: total number of cardiovascular events - 26 (14.8%) vs 47 (27%), p<0.01; number of cardiovascular catastrophes - 5 (3%) vs 15 (8.7%), p<0.05; number of days out of work because of exacerbation of IHD per 1 person/year - 2.4 vs 4.2, p<0.05 in groups " O" and " C" , respectively. Thus in the group " O" positive effect of PT on the course and outcomes of the disease was registered compared with the group " C" . The data obtained are indicative of sufficient efficacy of the used program of PT and feasibility of its application in practice of ambulatory rehabilitation of patients with IHD - survivors of acute coronary events. It also can be looked upon as a method of secondary prevention as results of the study showed its positive impact on risk factors and outcomes of the disease.

The aim was to explore the effect of negative pressure on the proliferation and metastasis of human pancreatic cancer SW1990 cells. Three groups were conducted in the work: normal control group (NC group, 0 mm Hg), low negative pressure group (LN group, -300 mm Hg), and high negative pressure group (HN group, -600 mm Hg). Cell morphological assay was conducted using an inverted Nikon TE2000-S microscope. Cell viability was assayed using cell counting kit-8 solution. Cell apoptosis was evaluated with flow cytometry. Cell migration was investigated using transwell assay. Compared to LN and HN groups, SW1990 cells in NC group grew quite well, showing a higher density. The NC group represented the highest cell viability. The HN group represented the lowest cell viability, which was lower than that of the LN group (P < 0.01). The apoptosis rate in NC group, LN group and HN group was 1.91% ± 0.13%, 2.31% ± 0.06% and 15.22% ± 0.81%, respectively (P < 0.05). The average number of migration cells in NC group was 53.60 ± 4.14 (× 200), which was decreased to 18.93 ± 3.67 and 11.07 ± 3.01 in LN group and HN group, respectively (P < 0.01). The negative pressure shows suppression effects on the proliferation and metastasis of human pancreatic cancer SW1990 cells. It is indicated that negative pressure may be involved in the development of human pancreatic cancer by influencing cell biological characteristics.

This work aims at investigating the effects of hypoxic preconditioning on hypoxia-inducible factor-1 alpha (HIF-1alpha) expression in the hippocampus of mice during acute and repeated hypoxic exposures. The mice were randomly divided into three groups and exposed, respectively, to hypoxia for 4 runs (group H4), 1 run (group H1), and 0 run (group H0). Reverse transcription-polymerase chain reaction (RT-PCR), Western blot, electrophoretic mobility shift assay (EMSA), and chromatin immunoprecipitation were used to examine the HIF-1alpha responses in the mouse hippocampus following exposure to hypoxia. The tolerance of mice to hypoxia increased significantly following acute and repetitive exposure to autoprogressive hypoxia. Total mRNA, total protein, and nuclear protein were extracted from the hippocampus for RT-PCR, Western blot, and EMSA, respectively. The HIF-1alpha mRNA levels were found to be increased in group H1 and decreased in group H4. The HIF-1alpha protein levels and HIF-1 DNA-binding activities were increased in group H1 and markedly increased in group H4. One of the HIF-1 target genes, vascular endothelial growth factor, increased in group H4. HIF-1 activation is thought to be involved in the protection of the brain of hypoxic preconditioned mice.

Instruments related to work are commonly illuminated from an ill-health perspective. The need for a concise and useable instrument in workplace health promotion governed the aim of this paper which is to present the development process and quality assessment of the Work Experience Measurement Scale (WEMS). A survey, using a questionnaire based on established theories regarding work and health, and a focus group study were performed in hospital settings in 2005 and 2006 respectively. A Principal Component Analysis (PCA) was used to statistically develop a model, and focus group interviews were made to compare quantitative and qualitative results for convergence and corroboration. The PCA resulted in a six factor model of dimensions containing items regarding management, reorganization, internal work experience, pressure of time, autonomy and supportive working conditions. In the analysis of the focus group study three themes appeared and their underlying content was compared to, and matched, with the dimensions of the PCA. The reliability, shown by weighted kappa values, ranged from 0.36 to 0.71, and adequate Cronbach's Alpha values of the dimensions were all above 0.7. The study validity, indicated by discriminant validity, with correlation values that ranged from 0.10 to 0.39, in relation to the content validity appeared to be good when the theoretical content of the WEMS was compared to the content of similar instruments. The WEMS presents a multidimensional picture of work experience. Its theoretical base and the psychometric properties give support for applicability and offer a possibility to measure trends in the work experience over time in health care settings. One intention of the WEMS is to stimulate the ability of organizations and the employees themselves to take action on improving their work experience. The conciseness of the instrument is intended to increase its usability.

Controlled patterns of daytime light exposure improve circadian adjustment in simulated night work.

Circadian misalignment between the endogenous circadian signal and the imposed rest-activity cycle is one of the main sources of sleep and health troubles in night shift workers. Timed bright light exposure during night work can reduce circadian misalignment in night workers, but this approach is limited by difficulties in incorporating bright light treatment into most workplaces. Controlled light and dark exposure during the daytime also has a significant impact on circadian phase and could be easier to implement in real-life situations. The authors previously described distinctive light exposure patterns in night nurses with and without circadian adaptation. In the present study, the main features of these patterns were used to design daytime light exposure profiles. Profiles were then tested in a laboratory simulation of night work to evaluate their efficacy in reducing circadian misalignment in night workers. The simulation included 2 day shifts followed by 4 consecutive night shifts (2400-0800 h). Healthy subjects (15 men and 23 women; 20-35 years old) were divided into 3 groups to test 3 daytime light exposure profiles designed to produce respectively a phase delay (delay group, n=12), a phase advance (advance group, n=13), or an unchanged circadian phase (stable group, n=13). In all 3 groups, light intensity was set at 50 lux during the nights of simulated night work. Salivary dim light melatonin onset (DLMO) showed a significant phase advance of 2.3 h (+/-1.3 h) in the advance group and a significant phase delay of 4.1 h (+/-1.3 h) in the delay group. The stable group showed a smaller but significant phase delay of 1.7 h (+/-1.6 h). Urinary 6-sulfatoxymelatonin (aMT6s) acrophases were highly correlated to salivary DLMOs. Urinary aMT6s acrophases were used to track daily phase shifts. They showed that phase shifts occurred rapidly and differed between the 3 groups by the 3rd night of simulated night work. These results show that significant phase shifts can be achieved in night workers by controlling daytime light exposure, with no nighttime intervention.

The research work was carried out to study the effect of Oral and Intrathecal Monechma Ciliatum on antinociception and EEG readings in Wistar Rats. Traditionally the extract is given to women in labour believed to reduce pain and ease parturition, though past works show that it has oesteogenic and oxytotic effects. The rats were divided into 5 major groups. Group 1 served as oral control group while groups 2 and 3 served as oral experimental groups and were treated with 500mg/kg and 1000mg/kg monechma ciliatum respectively. Group 4 served as intrathecal control group treated with intrathecal dextrose and group 5 received 1000mg/kg Monechma Ciliatrum intrathecally. The antinociceptive effect was analysed using a Von Frey's aesthesiometer. Monechma Ciliatum showed significant antinociceptive effect both orally and intrathecally, although it had a greater effect orally and during the first 15 minutes of intrathecal administration. EEG readings were also taken for all the groups and there was a decrease in amplitude and an increase in frequency for high dose (1000mg/ml) experimental groups and the mid brain electrodes produced a change from theta waves (3.5 - 7 waves per second) to alpha waves (7.5 - 13 waves per second) as seen in relaxed persons and caused decreased amplitudes and change in distribution seen in beta waves. Properties similarly accentuated by sedativehypnotic drugs.

Issues related to labour potential, its state and problems have consistently been a focus of attention for the International Labour Organisation (ILO). Its respective analysis shows that labour potential problems remain unresolved in many countries of the world. According to the World Health Organisation (WHO), adverse working conditions are among major factors of occupational disease development in Europe and the reason for disabilities of economically active population during 2.5% of their lifetime. The aim of the present study is to identify and analyse major risk factors, which have a bearing on people working in agriculture in the course of exercising their occupation, with account of forms of ownership of agricultural enterprises. Carried out was a cross-sectional study involving a sociological survey of 412 respondents - those working in agriculture - who made up the primary group and the control group. The study revealed 21 risk factors, 9 of which were work-related. A modified elementary cybernetic model of studying impact efficiency was developed with the view of carrying out a structural analysis of the sample group and choosing relevant methodological approaches. It has been established that harmful factors related to working environment and one's lifestyle are decisive in the agrarian sector, particularly for workers of privately owned businesses. For one out of three respondents harmful working conditions manifested themselves as industrial noise (31.7±3.4), vibration (29.0±2.1) trunk bending and constrained working posture (36.6±3.4). The vast majority of agricultural workers (91.6±2.5) admitted they could not afford proper rest during their annual leave; male respondents abused alcohol (70.6±3.0) and smoking (41.4±2.0 per 100 workers). The research established the structure of risk factors, which is sequentially represented by the following groups: behavioral (smoking, drinking of alcohol, rest during annual leave, physical culture), working environment and work activities (occupation, work experience, safety measures, working environment, organization and management), socioeconomic (education, financial situation).

A tutor's performance is often investigated as a stable teacher characteristic, isolated from the context in which the tutor functions. This study investigated the influence of a tutor's group-dynamics skills in differently functioning tutorial groups on performance ratings. Students' ratings of tutors' performances collected from 75 tutorial groups at one school over four different academic years were compared with the independent variables, groups' cohesion scores and sponging scores (the degree to which some students let others do the work), and the intervening variable, tutors' group-dynamics skills. Tutors with strong group-dynamics skills were assigned mean tutor's-performance scores of 7.4 (SD = 0.8) and 8.2 (SD = 0.5), respectively, by groups scoring low and high on cohesion. Tutors with low group-dynamics skills were rated 7.0 (SD = 1.1) and 7.4 (SD = 1.1) by the same groups. The same pattern held for sponging scores. Tutors who had strong group-dynamics skills received mean tutor's-performance scores of 8.1 (SD = 0.6) and 7.4 (SD = 0.8), respectively, from groups with low and high sponging scores. Tutors with weak group-dynamics skills were scored 7.6 (SD = 1.0) and 6.9 (SD = 1.1) by the same groups. Tutors possessing group-dynamics skills were rated higher by students than were tutors who lacked these skills, irrespective of the quality of a tutorial group's performance. A tutor who evaluates tutorial-group function on a regular basis and makes appointments with students based on these evaluations is seen as performing better than a tutor who does not.

To evaluate and compare the effectiveness of the combined regimen (consisting of condoms and emergency contraception pills (ECP)) and using condoms only for the purpose of preventing pregnancy. One-thousand-five-hundred-and-sixty-two (1,562) couples as volunteers enrolled at nine centers in Shanghai. Eight-hundred-and-twelve (812) were randomized to use male condoms and ECP (i.e., Levonorgestrel) as a back-up to condoms (the intervention group) and 750 to use male condoms only(the control group), according to their working unit. Participants were visited at admission and at the end of 1, 3, 6, 9, and 12 months. The cumulative life table rates were calculated for pregnancy and other reasons for discontinuation. The gross cumulative life table rates showed that the cumulative discontinuation rates for all reasons during the year of follow-up in the condoms plus emergency contraception group and the condoms only group were 7.76 ± 0.94 and 6.61 ± 0.91, respectively, per 100 women (χ2 = 0.41, p = 0.5227). The cumulative gross pregnancy rate of the condoms plus emergency contraception group and the condoms only group were 2.17 ± 0.52 and 1.25 ± 0.41, respectively, per 100 women (χ2 = 1.93, p = 0.1645). The Pearl Index in the condoms plus emergency contraception group and the condoms only group were 2.21% and 1.26%, respectively. Male condoms remain a highly effective contraceptive method for a period of one year while consistently and correctly used. In addition, the lowest pregnancy rate followed from perfect use condom.

In the present work, we evaluated the three generation reproductive toxicity of the genetically modified rice with insectresistant cry1Ac and sck genes. 120 Sprague-Dawley (SD) rats were divided into three groups which were fed with genetically modified rice diet (GM group), parental control rice diet (PR group) and AIN-93 control diet (both used as negative control) respectively. Bodyweight, food consumption, reproductive data, hematological parameters, serum chemistry, relative organ weights and histopathology for each generation were examined respectively. All the hematology and serum chemistry parameters, organ/body weight indicators were within the normal range or no change to the adverse direction was observed, although several differences in hematology and serum chemistry parameters (WBC, BUN, LDH of male rat, PLT, PCT, MPV of female rats), reproductive data (rate of morphologically abnormal sperm) were observed between GM rice group and two control groups. No macroscopic or histological adverse effects were found or considered as treatment-related, either. Overall, the three generation study of genetically modified rice with cry1Ac and sck genes at a high level showed no unintended adverse effects on rats's reproductive system. Copyright © 2016.

To evaluate the fit of a three-unit metal framework of fixed dental prostheses made by subtractive and additive manufacturing. One master model of metal was fabricated. Twenty silicone impressions were made on the master die, working die of 10 poured with Type 4 stone, and working die of 10 made of scannable stone. Ten three-unit wax frameworks were fabricated by wax-up from Type IV working die. Stereolithography files of 10 three-unit frameworks were obtained using a model scanner and three-dimensional design software on a scannable working die. The three-unit wax framework was fabricated using subtractive manufacturing (SM) by applying the prepared stereolithography file, and the resin framework was fabricated by additive manufacturing (AM); both used metal alloy castings for metal frameworks. Marginal and internal gap were measured using silicone replica technique and digital microscope. Measurement data were analyzed by Kruskal-Wallis H test and Mann-Whitney U-test (α=.05). The lowest and highest gaps between premolar and molar margins were in the SM group and the AM group, respectively. There was a statistically significant difference in the marginal gap among the 3 groups ( P <.001). In the marginal area where pontic was present, the largest gap was 149.39 ± 42.30 µm in the AM group, and the lowest gap was 24.40 ± 11.92 µm in the SM group. Three-unit metal frameworks made by subtractive manufacturing are clinically applicable. However, additive manufacturing requires more research to be applied clinically.

Long working hours and physical activity.

It is widely believed that persons employed in jobs demanding long working hours are at greater risk of physical inactivity than other workers, primarily because they have less leisure time available to undertake physical activity. The aim of this study was to test this hypothesis using prospective data obtained from a nationally representative sample of employed persons. Longitudinal data from the Household, Income and Labour Dynamics in Australia Survey (93,367 observations from 17,893 individuals) were used to estimate conditional fixed effects logistic regression models of the likelihood of moderate or vigorous physical exercise for at least 30 min, at least four times a week. No significant associations between long working hours and the incidence of healthy levels of physical activity were uncovered once other exogenous influences on activity levels were controlled for. The odds of men or women who usually work 60 or more hours per week exercising at healthy levels were 6% and 11% less, respectively, than those of comparable persons working a more standard 35-40 h/week; however, neither estimate was significantly different from 0 at 95% CI. The findings suggest that there is no trade-off between long working hours and physical activity in Australia. It is argued that these findings are broadly consistent with previous research studies from Anglo-Saxon countries (where long working hours are pervasive) that employed large nationally representative samples.

There has been a recent proposal to change the grading system of prostate cancer into a five-tier grade grouping system. The prognostic impact of this has been demonstrated in regards only to biochemical recurrence-free survival (bRFS) with short follow-up (3 years). Between 1990 and 2013, 847 consecutive men were treated with definitive external beam radiation therapy at a single academic center. To validate the new grade grouping system, bRFS, distant metastases-free survival (DMFS) and prostate cancer-specific survival (PCSS) were calculated. Adjusted Kaplan-Meier and multivariable Cox regression analyses were performed to assess the independent impact of the new grade grouping system. Discriminatory analyses were performed to compare the commonly used three-tier Gleason score system (6, 7 and 8-10) to the new system. The median follow-up of our cohort was 88 months. The 5-grade groups independently validated differing risks of bRFS (group 1 as reference; adjusted hazard ratio (aHR) 1.35, 2.16, 1.79 and 3.84 for groups 2-5, respectively). Furthermore, a clear stratification was demonstrated for DMFS (aHR 2.03, 3.18, 3.62 and 13.77 for groups 2-5, respectively) and PCSS (aHR 3.00, 5.32, 6.02 and 39.02 for groups 2-5, respectively). The 5-grade group system had improved prognostic discrimination for all end points compared with the commonly used three-tiered system (that is, Gleason score 6, 7 and 8-10). In a large independent radiotherapy cohort with long-term follow-up, we have validated the bRFS benefit of the proposed five-tier grade grouping system. Furthermore, we have demonstrated that the system is highly prognostic for DMFS and PCSS. Grade group 5 had markedly worse outcomes for all end points, and future work is necessary to improve outcomes in these patients.

The principal aim of this work is to study the velocity field in the Monoceros star-forming region using the radial velocity data available in the literature, as well as astrometric data from the Gaia first release. This region is a large star-forming complex formed by two associations named Monoceros OB1 and OB2. We have collected radial velocity data for more than 400 stars in the area of 8 × 12 deg2 and distance for more than 200 objects. We apply a clustering analysis in the subspace of the phase space formed by angular coordinates and radial velocity or distance data using the Spectrum of Kinematic Grouping methodology. We found four and three spatial groupings in radial velocity and distance variables, respectively, corresponding to the Local arm, the central clusters forming the associations and the Perseus arm, respectively.

Given the hazardous nature of the work in steel factories and that the staff has to deal with hazardous equipment and machines, improper sleep quality and drowsiness among the works tackles performance and boosts rate of job accidents. This study is aimed to survey the quality of sleep and sleepiness status and the pertinent factors among the workers in a rolling mill and a steel production company in Tehran, Iran. In a Cross-Sectional study 2011, 180 workers were selected randomly from a rolling mill and a steel production company in Tehran. A questionnaire was designed to collect demographic data and variables of work condition. Pitersborg's sleep quality questionnaire was used to survey quality and problems of Participants' sleep. Epworth Sleepiness questionnaire was used to deals with sleepiness during work, studying, watching TV, or during time spent in public. Average score of sleep quality for the fixed shift staff and changing shift staff were 7.5±2.82 and 8.49±2.95 respectively. Surveys of sleep quality for the two groups of the participants based on T-test showed a significant difference between the two groups so that the changing shift staff group suffered poorer sleep quality (p=0.03). Comparison of average drowsiness scores between the two groups of participants based on Mann-Whitney test showed no significant difference (p>0.005). Chi square test showed a significant difference between severity of drowsiness and type of working shift (p =0.028 and 0.009). Staff in revolving shifts suffers poor sleep quality comparing with staff with fixed working shift. Moreover, type of working shift greatly affects severity of drowsiness as staff at different work shift experienced different level of sleepiness. It is essential to survey sleep disorder of the staff in the industry and pay more emphasis on sleep disorder epidemic in other fields of industry.

To explore factors associated with long-term outcomes of work and marital status in individuals who had experienced a mild head injury (MHI), as well as those who had not. Population-based study using logistical regression analyses to investigate the impact of preinjury characteristics on work and marital status. Two groups of Vietnam-era Army veterans: 626 who had experienced a MHI an average of 8 years before examination, and 3,896 who had not. Demographic characteristics, concurrent medical conditions, early life psychiatric problems, loss of consciousness (LOC), and interactions among these variables were used to predict current work and marital status. Multiple variables were associated with work and marital status in the sample with MHI, accounting for approximately 23% and 17% of the variance in these two outcome variables, respectively. In contrast, the same factors accounted for significantly less variance in outcome in the sample without a head injury-13.3% and 9.4% for work and marital status, respectively. These findings suggest a more potent role for and increased vulnerability to the influence of demographic, medical, and psychiatric factors on outcomes after a MHI. That is, MHI itself moderates the influence of preinjury characteristics on work and marital status. In addition, in those who had a MHI, moderator relationships were found between education and LOC for both work and marital status. Similarly, complex moderator relationships among race, region of residence, and LOC were found for both work and marital status outcomes.

To determine presence of suprascapular nerve entrapment in a group of newsreel cameramen. Thirty-six men working as newsreel cameramen participated in the study. In addition to musculoskeletal and neurologic examinations, bilateral suprascapular nerve conduction studies and needle electromyography were performed. A group of 19 healthy, male volunteers were included in the study as normal controls for suprascapular nerve conduction studies. In newsreel cameramen, mean suprascapular nerve latency was 3.20 +/- 0.56 msec and 2.84 +/- 0.36 msec for right and left shoulders, respectively (P = 0.001). The mean latency difference between right and left suprascapular nerves was -0.05 +/- 0.19 msec in the control group and 0.36 +/- 0.58 msec in the cameramen group (P < 0.001). Six subjects' right suprascapular nerve motor latencies were 2 SD above the normal mean values. There was no relationship between suprascapular nerve latencies and the age, professional life, and number of hours worked daily by the subjects. Carrying a heavy, mobile camera on the shoulder might cause suprascapular nerve entrapment in newsreel cameramen. This could be considered an occupational disorder of the suprascapular nerve, like meat-packer's neuropathy.

Shift work disrupts the circadian rhythm and may cause menstruation disorders. This study assessed the impact of shift work on menstrual cycle in a population of Chinese nurses. Questionnaires on menstrual characteristics and shift schedules were sent to female nurses of the First Affiliated Hospital of Sun Yat-sen University (FAHSYSU) and Guanghua Hospital of Stomatology (GHHS), affiliated to Sun Yat-sen University. Part I was a cross-sectional study and included 139 nurses in GHHS who had regular 8:00-17:30 working (non-shift group), and 334 nurses from FAHSYSU who worked shifts, a response rate of 67.5 % and 59.6 %, respectively (age ≤ 50 years). Menstrual patterns were compared and age-adjusted relative risks of shift work were analyzed. Part II was a nested case-control study. Cases were nurses in Part I who had regular cycle with mean cycle length (MCL) of 25-31 days and but at least 3 days variation in MCL after starting shift work (n = 45). Controls consisted of 67 nurses with matching shift patterns and age, but no MCL changes. A control non-shift age-matched group consisted of 30 GHHS nurses with no MCL changes. A follow-up second questionnaire was sent 2 years later. In Part I, the shift group had a significantly higher proportion of nurses with menstrual cycle irregularity. The proportion of nurses with a cycle of 25-31 days decreased from 81.7 to 67.8 % after changing to shift work. Logistic regression analysis showed that night shift frequency was the only risk factor associated with cycle shortening. After adjusting for age, MCL was shorter when night work was performed > 7 times per month. In Part II, the mean change in MCL in the case group, including prolongation or shortening, was 4.115 ± 2.084 days after shift working. In the 2 years' follow-up, the MCL of the study group did not recover to the original length. Rotating shift work can increase the prevalence of menstrual cycle irregularity. Night shift frequency was the only risk factor associated with cycle reduced. Changes in MCL did not show recovery over a follow-up period of 2 years.

Job stress is a great problem in developed countries of the world, but in Yugoslavia, it is increased due to additional reasons associated with economic crisis in the society. Health services and health workers are in particularly difficult conditions. The aim of this paper was to examine sources and causes of job stress in health workers. The research was undertaken among health workers treated at Health Centre "Hospital" in Novi Sad. The study group included health workers--doctors, nurses and laboratory workers, and the control group included the rest of non-medical staff. Adapted Siegrist questionnaire was used. Three factors were examined: extrinsic efforts (disturbances at work, sense of great job responsibility and the need for overtime work); intrinsinc efforts (major criticism, thinking about the job from the early morning, getting nervous because of minor problems, discontentment because of unsolved problems at work, relaxation at home and so on), and low reward (respect from the superiors and colleagues, support and security at workplace). Answers were scored indicating intensity (high, moderate, low, not at all). Statistic analysis included testing the level of significance in health workers in relation to non-medical staff (t test and Fisher's exact test). Applying the scoring system it has been established that health workers are exposed to greater job stress, great sense of very high job responsibility and frequent overtime work (p < 0.001) than the control group. In regard to answers from the second group--intrinsic effort and low reward, there was no statistiscal significance between the study and control group. Generally, high level of risk factors was established, especially presence of one or more risk factors. Job stress increases absenteeism, reduces work productivity, causes higher expenses of medical treatment, rehabilitation and staff retraining. It is of great importance to identify factors which cause job dissatisfaction in order to decrease them to the lowest level. High sense of responsibility in health workers is a course of job stress.

This study was conducted to determine whether there was any exposure to toluene, xylene and benzene and to assess the health impact of these solvents on workers in furniture enterprises in Karabaglar, Izmir. This cross-sectional study covered furniture enterprises in Karabaglar, Izmir. This study was comprised of an exposed group consisting of workers engaged in painting and varnishing and therefore exposed either directly or indirectly toluene, xylene and benzene in the workplace and the non-exposed group engaged in other aspects of production. While a total of 261 individuals completed questionnaires, 210 workers agreed to provide blood samples. Blood solvents levels were determined using gas chromatograph at Ege University, Intoxication Research and Application Centre. The modified EUROQUEST questionnaire was used to assess neuropsychological symptoms and neurological and general examination were performed. Occupational and exposure history, demographic and work-related information was collected. In this study of workers, blood toluene and benzene levels were found to be significantly higher among those engaged in painting and varnishing compared to those who perform other tasks. The average blood toluene and benzene concentrations among exposed workers were 6.95 times and 1.64 times respectively higher than those in the nonexposed groups. Smokers and participants who worked in excess of 8 hours/day had higher blood toluene and benzene levels. The most frequently work-related health complaints were back pain, allergies and asthma. No differences were found in the average scores in the neuropsychological symptoms questionnaire between exposed and non-exposed groups. Neurological examination of two individuals with these complaints revealed a loss of reflexes. The workers were unaware that they were being exposed to solvents at work. Tobacco smoke is a major source of internal exposure to benzene. Improving working conditions in furniture work places is a priority.

To investigate the features of intelligence development, facial expression recognition ability, and the association between them in children with autism spectrum disorder (ASD). A total of 27 ASD children aged 6-16 years (ASD group, full intelligence quotient >70) and age- and gender-matched normally developed children (control group) were enrolled. Wechsler Intelligence Scale for Children Fourth Edition and Chinese Static Facial Expression Photos were used for intelligence evaluation and facial expression recognition test. Compared with the control group, the ASD group had significantly lower scores of full intelligence quotient, verbal comprehension index, perceptual reasoning index (PRI), processing speed index（PSI), and working memory index (WMI) (P<0.05). The ASD group also had a significantly lower overall accuracy rate of facial expression recognition and significantly lower accuracy rates of the recognition of happy, angry, sad, and frightened expressions than the control group (P<0.05). In the ASD group, the overall accuracy rate of facial expression recognition and the accuracy rates of the recognition of happy and frightened expressions were positively correlated with PRI (r=0.415, 0.455, and 0.393 respectively; P<0.05). The accuracy rate of the recognition of angry expression was positively correlated with WMI (r=0.397; P<0.05). ASD children have delayed intelligence development compared with normally developed children and impaired expression recognition ability. Perceptual reasoning and working memory abilities are positively correlated with expression recognition ability, which suggests that insufficient perceptual reasoning and working memory abilities may be important factors affecting facial expression recognition ability in ASD children.

The influence of applying insurance medicine guidelines for depression on disability assessments

PubMed Central

2013-01-01

Background In the current study we report on the effects of an implementation strategy in the form of a training programme on the assessed work limitations of a client with depression by insurance physicians (IPs) participating in a RCT. These assessed work limitations of a client were in the form of scores on the List of Functional Abilities (LFA). Method We conducted a randomised controlled trial (RCT) for IPs in which we compared the intervention of a specially developed training programme with the usual methods of implementation and training currently used. The outcome was the mean sum score and the inter-rater reliability (Intraclass Correlation Coefficient, ICC) of the LFA scores. These LFA scores were scored by the IPs participating in the RCT for the work limitations of the cases presented in different videos, two videos before the training and two after the training of the intervention group. Results At baseline, the intervention group (IG) consisted of 21 IPs and the control group (CG) of 19. For one participant of the IG and for one of the CG the LFAs of the two case reports after training were not available. Before training the sum scores for the first case report did not differ significantly between the groups, while the mean sum score was higher in the IG than in the CG for the second case report. For both case reports after training a higher score was found in the IG than in the CG. The inter-rater reliability measured for the two case reports before training was about the same in the IG and the CG: 0.64 and 0.65, respectively. For the two case reports after training, the ICC was higher in the IG than in the CG: 0.69 and 0.54, respectively. This difference was not significant however. Conclusion It would appear that the implementation of a specially designed training programme on guidelines for depression may lead to greater inter-rater reliability in the assessments by insurance physicians of the work limitations of clients with depression. It is, however, important to note that insurance physicians who receive training may find more work limitations than those who do not.

Growing evidence suggests that gender-blind assessment of exposure may introduce exposure misclassification, but few studies have characterised gender differences across occupations and industries. We pooled control responses to job-specific, industry-specific and exposure-specific questionnaires (modules) that asked detailed questions about work activities from three US population-based case-control studies to examine gender differences in work tasks and their frequencies. We calculated the ratio of female-to-male controls that completed each module. For four job modules (assembly worker, machinist, health professional, janitor/cleaner) and for subgroups of jobs that completed those modules, we evaluated gender differences in task prevalence and frequency using χ(2) and Mann-Whitney U tests, respectively. The 1360 female and 2245 male controls reported 6033 and 12 083 jobs, respectively. Gender differences in female:male module completion ratios were observed for 39 of 45 modules completed by ≥20 controls. Gender differences in task prevalence varied in direction and magnitude. For example, female janitors were significantly more likely to polish furniture (79% vs 44%), while male janitors were more likely to strip floors (73% vs 50%). Women usually reported more time spent on tasks than men. For example, the median hours per week spent degreasing for production workers in product manufacturing industries was 6.3 for women and 3.0 for men. Observed gender differences may reflect actual differences in tasks performed or differences in recall, reporting or perception, all of which contribute to exposure misclassification and impact relative risk estimates. Our findings reinforce the need to capture subject-specific information on work tasks. Published by the BMJ Publishing Group Limited.

To correlate workgroup engagement in nursing teams and the clinical learning experience of nursing students. Work engagement plays a pivotal role in explaining motivational dynamics. Nursing education is workplace-based and, through their clinical placements, nursing students develop both their clinical competences and their professional identity. However, there is currently a lack of evidence on the role of work engagement related to students' learning experiences. A total of 519 nurses and 519 nursing students were enrolled in hospital settings. The Utrecht Work Engagement Scale (UWES) was used to assess work engagement, and the Clinical Learning Environment and Supervision plus nurse Teacher (CLES+T) scale was used to assess students' learning experience. A multilevel linear regression analysis was performed. Group-level work engagement of nurses correlated with students' clinical learning experience (β = 0.11, P < 0.001). Specifically, the 'absorption' and 'dedication' factors mostly contributed to enhancing clinical learning (respectively, β = 0.37, P < 0.001 and β = 0.20, P < 0.001). Nursing teams' work engagement is an important motivational factor to enhance effective nursing education. Nursing education institutions and health-care settings need to conjointly work to build effective organisational climates. The results highlighted the importance of considering the group-level analysis to understand the most effective strategies of intervention for both organisations and nursing education. © 2015 John Wiley & Sons Ltd.

Global Earth Observation System of Systems (GEOSS): Initial Actions to Enhance Data Sharing to Meet Societal Needs

2006-05-01

Over 60 nations and 50 participating organizations are working to make the Global Earth Observation System of Systems (GEOSS) a reality. The U.S. contribution to GEOSS is the Integrated Earth Observation System (IEOS), with a vision of enabling a healthy public, economy and planet through an integrated, comprehensive, and sustained Earth observation system. The international Group on Earth Observations (GEO) and the U.S. Group on Earth Observations have developed strategic plans for both GEOSS and IEOS, respectively, and are now working the first phases of implementation. Many of these initial actions are data architecture related and are being addressed by architecture and data working groups from both organizations - the GEO Architecture and Data Committee and the USGEO Architecture and Data Management Working Group. NOAA has actively participated in both architecture groups and has taken internal action to better support GEOSS and IEOS implementation by establishing the Global Earth Observation Integrated Data Environment (GEO IDE). GEO IDE provides a "system of systems" framework for effective and efficient integration of NOAA's many quasi-independent systems, which individually address diverse mandates in such areas resource management, weather forecasting, safe navigation, disaster response, and coastal mapping among others. GEO IDE will have a services oriented architecture, allowing NOAA Line Offices to retain a high level of independence in many of their data management decisions, and encouraging innovation in pursuit of their missions. Through GEO IDE, NOAA partners (both internal and external) will participate in a well-ordered, standards-based data and information infrastructure that will allow users to easily locate, acquire, integrate and utilize NOAA data and information. This paper describes the initial progress being made by GEO and USGEO architecture and data working groups, a status report on GEO IDE development within NOAA, and an assessment of how GEO IDE can facilitate greater progress in GEOSS and IEOS development.

This in vitro study aimed at comparing the effect of agitating the final irrigant solutions of root canal by ultrasonic or using 808 nm Diode laser on the apical seal of canal. A total of 90 extracted human maxillary central incisors were prepared up to size #45 and were randomly assigned to 4 experimental groups ( n =20) and two control groups ( n =5) respectively, as follows: I ): 3 mL of 5.25% NaOCl was agitated as final irrigant solution with ultrasonic for 30 sec. The ultrasonic tip was 1 mm shorter than the working length, II ): 3 mL of 5.25% NaOCl was agitated as final irrigant with 808 nm Diode laser for 30 sec. Fiber tip, placed in 1 mm shorter from working length was spirally moved coronally, III ): 3 mL of 17% EDTA was agitated as final irrigant with 808 nm Diode laser for 30 sec and was applied similar to group II, IV ): 3 mL of 17% EDTA was stimulated as final irrigant with ultrasonic for 30 sec and was applied similar to I. Apical seal was assessed by Dual Chamber technique using Bovine Serum Albumin protein. Kruskal-Wallis and Mann Whitney tests were used with significance level lower than 0.05% for statistical analysis. The average leakage in the negative control, positive control, and groups I, II, III, IV were: 0.00, 13.5±5.1, 1.72±2.9, 5.12±5.6, 3.36±3.7, 2.4±4.2, respectively. Statistical analysis showed significant difference between groups ( P <0.05). There was a significant difference between groups 1 and 2 in terms of protein leakage . Agitating 5.25% sodium hypochlorite solution as the final irrigant with ultrasonic is more effective in apical leakage reduction compared to other groups.

Humic acids (HAs) determine the distribution, toxicity, bioavailability, and ultimate fate of heavy metals in the environment. In this work, ten HA fractions (F1-F10) were used as adsorbent, which were sequentially extracted from natural sediments of Lake Wuliangsuhai, to investigate the binding characteristics of Cu 2+ to HA. On the basis of the characterization results, differences were found between the ten extracted HA fractions responding to their elemental compositions and acidic functional groups. The characterization results reveal that the responses of ten extracted HA fractions to their elemental compositions and acidic functional groups were different. The O/C and (O + N)/C ratio of F1-F8 approximately ranged from 0.66 to 0.53 and from 0.72 to 0.61, respectively; the measured results showed that the contents of phenolic groups and carboxyl groups decreased from 4.46 to 2.60 mmol/g and 1.60 to 0.58 mmol/g, respectively. The binding characteristics of Cu 2+ to the ten HA fractions were well modeled by the bi-Langmuir model; the binding behavior of Cu 2+ to all the ten HA fractions were strongly impacted by pH and ionic strength. The FTIR and SEM-EDX image of HA fractions (pre- and post-adsorption) revealed that carboxyl and phenolic groups were responsible for the Cu 2+ sorption on the ten sequentially extracted HA fractions process, which is the same with the analysis of the ligand binding and bi-Langmuir models Accordingly, the adsorption capacity of the former HA fractions on Cu 2+ were higher than the latter ones, which may be attributed to the difference of carboxyl and phenolic group contents between the former and latter extracted HA fractions. Additionally, the functional groups with N and S should not be neglected. This work is hopeful to understand the environmental effect of humic substances, environmental geochemical behavior, and bioavailability of heavy metals in lakes.

To assess and compare clinical observations and interpretations by physicians trained in biopsychosocial internal medicine (group A) and a control group (C) of physicians with no such special training. A verbatim first-interview of a 36-year old woman, seen for consultation by RHA, was presented to both groups (A, trained physicians: n = 30, and C, controls: n = 29). The patient's symptoms included: shaky knees, strange sensations in the abdomen and chest, insecurity and dizziness. The symptoms had begun before her final nursing- exam and exacerbated on her mother's 60th birthday two months later. The patient's mother is the sole caretaker for the patient's sister, who also attended the birthday party. The patient's sister is 19 and had been diagnosed with storage disease and is wheelchair-bound. The doctors were asked to record their observations and interpretations while reviewing the case report. Group A-physicians mentioned and interpreted the physician-patient relationship and the patient's body language as described in the case report more often (p = 0.002, Wilcoxon-Mann-Whitney rank sum test (RS)), mentioned physical symptoms more often (p = 0.0099, Fisher's exact test (FE)) and more often interpreted illness settings with respect to the patient's fear and guilt (Fisher's exact test, p = 0.007 and p = 0.015). A precise integrative diagnosis (life events leading to stress, the latter evoking fear and guilt, leading to symptoms of the fight-flight reaction) was suggested by 7 of group A and 4 of group C. Extensive laboratory work-up and requests for consultations were more frequently asked for by the C group (p = 0.048, RS). Residency training in biopsychosocial medicine in an Internal Medicine Department increased sensitivity to and interpretation of biological and psychosocial data many years after the training and decreased the extent of work-up and consultation costs. However it only tended to enhance psychosomatic conceptualisation with respect to anxiety/guilt/hyperventilation and conversion symptoms.

A number of studies suggest that age differences in working memory may be attributed to age-related differences in inhibitory efficacy. Nevertheless, little is known about the impact of intrusive thoughts, which occurs in everyday situations on working memory performance. This study investigates the role of cognitive and everyday inhibition mechanisms in working memory performance. Young, young-old and old-old adults performed a working memory task and the White Bear Suppression Inventory (WBSI). Results showed a decrease in working memory, and in inhibitory efficacy with age. In addition, old-old adults obtained higher scores in the three factors of the WBSI. Working memory performance was related to working memory control of interfering information in all age groups, and also to the tendency to suppress thoughts in old-old adults. The latter result was in the opposite direction with respect to observations collected with younger adults. Taken together, our results suggest the crucial role of intrusive thoughts in the functional capacity of working memory in late adulthood.

Early studies on manganese (Mn) exposure have demonstrated that this transition metal affects dopamine neurotransmission. Dopamine serves as a tonic inhibitor of prolactin release in the anterior hypophysis. Our aim was to determine the relation between serum prolactin levels and manganese-exposure. Whole blood was collected from 95 non-exposed control subjects and 179 manganese-exposed male welders. Whole blood manganese was analyzed by Inductively Coupled Plasma--Mass Spectrometer on Agilent 7700 (Agilent Technologies, USA). Serum prolactin levels (PRL), aspartate transaminase (AST), alanine transaminase (ALT), urea, creatinine, soduim (Na), potassium (K) were analyzed by immunological and spectrophotometric methods on Roche E170 Modular System (Roche Diagnostics, Mannheim, Germany). The mean ages for control and manganese-exposed group were 40.5 ± 7.8 and 39.5 ± 8.7, respectively (p = 0.258). The mean working period (years) for control and manganese-exposed group were 17.4 ± 9.8 and 18.2 ± 7.7 years, respectively (p = 0.581). Serum AST and potassium levels were significantly higher in control group than manganese-exposed group (p = 0.002 and p = 0.048, respectively) and body-mass index (BMI) was significantly lower in control group than manganese-exposed group (p = 0.033). There was a significantly positive correlation between whole blood manganese levels and serum prolactin (r = 0.860, p < 0.001). Serum ALT levels were positively correlated with serum AST, urea and sodium (r = 0.315, p < 0.001; r = 0.121, p = 0.046; r = 0.130, p = 0.031). Serum prolactin level is a diagnostic marker for determining the effect of manganese-exposure.

In previous work we have developed a formulation of quantum mechanics in non-inertial reference frames. This formulation is grounded in a class of unitary cocycle representations of what we have called the Galilean line group, the generalization of the Galilei group that includes transformations amongst non-inertial reference frames. These representations show that in quantum mechanics, just as is the case in classical mechanics, the transformations to accelerating reference frames give rise to fictitious forces. A special feature of these previously constructed representations is that they all respect the non-relativistic equivalence principle, wherein the fictitious forces associated with linear acceleration canmore » equivalently be described by gravitational forces. In this paper we exhibit a large class of cocycle representations of the Galilean line group that violate the equivalence principle. Nevertheless the classical mechanics analogue of these cocycle representations all respect the equivalence principle. -- Highlights: •A formulation of Galilean quantum mechanics in non-inertial reference frames is given. •The key concept is the Galilean line group, an infinite dimensional group. •A large class of general cocycle representations of the Galilean line group is constructed. •These representations show violations of the equivalence principle at the quantum level. •At the classical limit, no violations of the equivalence principle are detected.« less

The present study focuses on math and related skills among 32 girls with fragile X (n = 14) or Turner (n = 18) syndrome during late elementary school. Performance in each syndrome group was assessed relative to Full Scale IQ-matched comparison groups of girls from the general population (n = 32 and n = 89 for fragile X syndrome and Turner syndrome, respectively). Differences between girls with fragile X and their comparison group emerged on untimed arithmetic calculations, mastery of counting skills, and arithmetic problem verification accuracy. Relative to girls in the comparison group, girls with Turner syndrome did not differ on untimed arithmetic calculations or problem verification accuracy, but they had limited mastery of counting skills and longer response times to complete the problem verification task. Girls with fragile X or Turner syndrome also differed from their respective comparison groups on math-related abilities, including visual-spatial, working memory, and reading skills, and the associations between math and those related skills. Together, these findings support the notion that difficulty with math and related skills among girls with fragile X or Turner syndrome continues into late elementary school and that the profile of math and related skill difficulty distinguishes the two syndrome groups from each other.

The main objective of the present study was to investigate relative personal fit as the association between rated needs and preferences for work hours, on the one hand, and actual work hours, on the other hand, in three groups (hospital, call-center, and police) working with periodic self-rostering. We also examined the association between personal fit and satisfaction with the work schedule and preference for a fixed and regular shift schedule, respectively. We collected questionnaire data and objective work hour data over 6-12 months from the computerized self-rostering system. The response rate of the questionnaire was 69% at the hospital and call-center and 98% among the police. In total, 29 433 shifts for 285 shift workers were included in the study. Data was analyzed by means of mixed ANOVA, Kendal tau correlations and ordinal (proportional odds) logistic regression. The results show that evening types worked relatively more hours during the evening and night hours compared to morning types as an indication of relative personal fit. Relative personal fit was also found for long shift, short rest, and morning-, evening- and night-shift frequency, but only personal fit related to morning, evening and night-shift was associated with satisfaction with work hours. Reported conflicts at the workplace about work hours and problems with lack of predictability of time for family/leisure activities, was associated with poor satisfaction and a preference for a fixed shift schedule. The present study shows that periodic self-rostering is associated with relative personal fit, in particular with respect to night, evening, and morning work. Personal fit seems to be associated with satisfaction with work hours and may be a moderator of tolerance to shift work exposure.

We all have friends and foes. In the study of complex networks, such a pairwise interaction is described by a directed link since the relation is not necessarily symmetric. We study a real network constructed from a survey in which each individual chooses five members (s)he wants to work with, and other five (s)he does not like to work together. Although everyone's outdegrees for such like and dislike links are fixed to five, respectively, it is found that indegree sequence for each type of links exhibits very different behaviors. We also pursue to answer the question of proper divisions of the organization based on the concept of happiness defined for each directed relation. For example, two individuals connected by like (dislike) links in both directions are happy if they belong to the same (different) group(s). We then adopt the framework of the q-state Potts model with long-ranged ferromagnetic and antiferromagnetic interactions and discuss the group structure in the organization that minimizes a suitably defined unhappiness.

Modeling breast cancer progression and the effect of various risk is helpful in deciding when a woman should start and end screening, and how often the screening should be undertaken. We modeled the natural progression of breast cancer using a hidden Markov process, and incorporated the effects of covariates. Patients are women aged 50-59 (older) and 40-49 (younger) years from the Canadian National Breast Screening Studies. We included prevalent cancers, estimated the screening sensitivities and rates of over-diagnosis, and validated the models using simulation. We found that older women have a higher rate of transition from a healthy to preclinical state and other causes of death but a lower rate of transition from preclinical to clinical state. Reciprocally, younger women have a lower rate of transition from a healthy to preclinical state and other causes of death but a higher rate of transition from a preclinical to clinical state. Different risk factors were significant for the age groups. The mean sojourn times for older and younger women were 2.53 and 2.96 years, respectively. In the study group, the sensitivities of the initial physical examination and mammography for older and younger women were 0.87 and 0.81, respectively, and the sensitivity of the subsequent screens were 0.78 and 0.53, respectively. In the control groups, the sensitivities of the initial physical examination for older and younger women were 0.769 and 0.671, respectively, and the sensitivity of the subsequent physical examinations for the control group aged 50-59 years was 0.37. The upper-bounds for over-diagnosis in older and younger women were 25% and 27%, respectively. The present work offers a basis for the better modeling of cancer incidence for a population with the inclusion of prevalent cancers.

There is still controversy as to the efficacy of light activation used in tooth whitening. The purpose of this study was to evaluate the effect of light activation on tooth color change relative to the artificial dye color. Extracted human third molars (160) were randomly distributed into eight groups of 20 specimens each based on artificial staining and use of light activation. All groups received three 45-minute sessions of in-office whitening at 3-day intervals. Color measurements were performed with an intraoral spectrophotometer at baseline prior to staining (T0), after artificial staining (T1), 1-day--(T2), and 1-week--(T3) post-whitening. Color differences were calculated relative to after artificial staining color parameters (L*1, a*1, b*1) with the use of a software analysis program enabling synchronization of two images. Within the same staining groups, the light-activated samples exhibited a greater color change than their nonlight-activated counterparts. However, only in the case of the yellow-stained samples at 1-day post-whitening was there a significant difference between the nonlight-activated and light-activated groups (Tukey's post hoc multiple comparison test for pairwise comparisons, p < 0.05). Light activation is a valid method for enhancing the efficacy of tooth whitening with respect to overall color change and works best with yellow stains. Light activation is a valid method for enhancing the efficacy of tooth whitening with respect to overall color change and works best with yellow stains.

Many low-and middle-income countries (LMIC) of the World Health Organization (WHO) European Region have introduced social health insurance payroll taxes after the political transition in the late 1980s, combined with budget transfers to allow for exempting specific population groups from paying contributions, such as those outside formal sector work and in particular vulnerable groups. This paper assesses the institutional design aspects of such financing arrangements and their performance with respect to universal health coverage progress in LMIC of the European region. The study is based on a literature review and review of secondary databases for the performance assessment. Such financing arrangements currently exist in 13 LMIC of that region, with strong commonalities in institutional design: This includes a wide range of different eligible population groups, mostly mandatory membership, integrated pools for both the exempted and contributors, and relatively comprehensive benefit packages. Performance is more varied. Enrolment rates range from about 65 % to above 95 %, and access to care and financial protection has improved in several countries. Yet, inequities between income quintiles persist. Budget transfers to health insurance arrangements have helped to deepen UHC or maintain achievements with respect to UHC in these European LMICs by covering those outside formal sector work, and in particular vulnerable population groups. However, challenges remain: a comprehensive benefit package on paper is not enough as long as supply side constraints and quality gaps as well as informal payments prevail. A key policy question is how to reach those so far uncovered.

It has been reported that an exaggerated systolic blood pressure (ESBP) response during exercise, even if resting blood pressure is normal, is associated with an increased risk of future hypertension and cardiovascular disease (CVD). This study was designed to investigate the relationships of work duration, sleep duration and number of holidays with blood pressure response during an exercise stress test among normotensive workers. The subjects were 362 normotensive workers (79 males and 283 females; age, 49.1 years). A multi-stage graded submaximal exercise stress test was performed on each subject using an electric bicycle ergometer. The workload was increased every 3 minutes, and blood pressure was measured at rest and during the last 1 minute of each stage. In this study, an ESBP response during exercise was defined according to the criteria of the Framingham Study (peak systolic blood pressure ≥210 mmHg in males, or ≥190 mmHg in females). Working environments, work duration, sleep duration, number of holidays, and physical activity during commuting and work, and leisure time exercise duration were evaluated using a questionnaire. An ESBP response during exercise was observed in 94 (26.0%) workers. The adjusted odds ratio for the prevalence of an ESBP response during exercise was found to be significantly higher with an increase in work duration, decreases in sleep duration and number of holidays (p<0.05, respectively). Moreover, the highest work duration with lowest sleep duration and number of holidays groups had significantly higher adjusted odds ratio for the prevalence of an ESBP response during exercise than the lowest work duration with highest sleep duration and number of holidays groups (p<0.05, respectively). Based on our results, we consider that the assessment of blood pressure response during exercise and daily life are necessary to prevent the incidence of future hypertension, CVD and death due to overwork in workers with long-work duration, short sleep duration and small number of holidays.

Randomized controlled trials (RCTs) of interventions aimed at reducing work-related stress indicate that cognitive behavioural therapy (CBT) is more effective than other interventions. However, definitions of study populations are often unclear and there is a lack of interventions targeting both the individual and the workplace. The aim of this study was to determine whether a stress management intervention combining individual CBT and a workplace focus is superior to no treatment in the reduction of perceived stress and stress symptoms and time to lasting return to work (RTW) in a clinical sample. Patients with work-related stress reactions or adjustment disorders were randomly assigned to an intervention group (n = 57, 84.2% female) or a control group (n = 80, 83.8% female). Subjects were followed via questionnaires and register data. The intervention contained individual CBT and the offer of a workplace meeting. We examined intervention effects by analysing group differences in score changes on the Perceived Stress Scale (PSS-10) and the General Health Questionnaire (GHQ-30). We also tested if intervention led to faster lasting RTW. Mean baseline values of PSS were 24.79 in the intervention group and 23.26 in the control group while the corresponding values for GHQ were 21.3 and 20.27, respectively. There was a significant effect of time. 10 months after baseline, both groups reported less perceived stress and improved mental health. 4 months after baseline, we found significant treatment effects for both perceived stress and mental health. The difference in mean change in PSS after 4 months was - 3.09 (- 5.47, - 0.72), while for GHQ it was - 3.91 (- 7.15, - 0.68). There were no group differences in RTW. The intervention led to faster reductions in perceived stress and stress symptoms amongst patients with work-related stress reactions and adjustment disorders. 6 months after the intervention ended there were no longer differences between the groups.

To analyze physician work production over a 5-year period to discover trends in productivity. Surgical workforce calculations over the past 25 years have projected major oversupply as well as looming shortages. Recent studies indicate that demand for surgical services will increase over the next two decades as the population ages and develops age related chronic diseases. This study examines actual physician productivity to determine whether there is capacity for increased work output in response to projected increases in demand. Physician productivity data as measured by relative value units were obtained from the Medical Group Management Association Physician Compensation Reports for a 5-year period. Surgeons were compared with nonsurgeons and across subspecialties. Surgeon and nonsurgeon productivity in terms of relative value units remained relatively stable over the study period; surgical:nonsurgical productivity per provider was 1.30-1.46:1. Surgeons produce a significant amount of the total work in multi-specialty medical groups. These results may indicate that the surgical and general surgical workforce has reached a plateau with respect to clinical productivity. Predicted increases in demand for procedure-based work to care for the aging population are likely to be difficult to meet with the available workforce.

The property of mercury to amalgamate with other metals is used to create a material for filling teeth. This material remains the cheapest and most efficient in tooth restoration. Mercurial toxicity has been documented since Antiquity but the metal remains widely used in some countries. This study compared mercury impregnation in dentists and dental assistants in Monastir (Tunisia) to another population not exposed professionally. A cross-sectional study was made on 52 dentists and dental assistants working in private offices and in the stomatology unit of the Monastir teaching hospital, with a control group of 52 physicians and nurses working in the Monastir Fattouma Bourguiba hospital. The groups were paired according to age and gender. The study lasted three months. A questionnaire investigated the socioprofessional features of the study population, non professional mercury exposure, work environment, the various amalgam handling and preparation techniques, and preventive hygiene measures. Urinary and salivary sampling was performed so as to prevent any accidental mercurial contamination. Mercury level was assessed by atomic absorption spectroscopy in an automatic sampler, urine creatinine with Jaffé's colorimetric reaction. The results of mercury level assessment were expressed in microg/g of creatinine, salivary mercury in mug/l. The statistical analysis was made with the Epi.info 6 software. Khi(2) and Fisher tests were used to compare qualitative variables. The ANOVA test was used to compare averages with a statistic significance threshold at 0.05. Sixty-one percent of individuals with risk exposure worked in a dental clinic. Bruxism and onychophagia were more important in the control group with a significant statistical difference (respectively, p=0.01 and p<0.0001). The urinary and salivary mercury levels were significantly increased in the exposed group, with respective values of 20.4+/-42.4microg/g of creatinine and 10.6+/-13.02microg/l versus 0.04+/-0.3microg/g of creatinine and 0microg/l in the control group. Disposing of amalgam waste was inadequate in 94% of the cases. The variation of mercury in urine was significantly influenced by the presence of fabric curtains (p=0.04). Eating lunch at meals at the work place was also linked to a significant increase of mercury levels in urine (p=0.04). The storage mode of mercury in open containers was a significant factor for variation of mercury level (p=0.03). Most dentists' private offices in Monastir do not comply or comply weakly with prevention measures linked to risk of mercury poisoning. Awareness campaigns were launched as well as actions for the improvement of work conditions: efficient aspiration of offices containing fixed sources of mercury, adequate storage of mercury and waste, and compliance to occupational hygiene rules.

Review Of The Working Group On Precession And The Ecliptic

NASA Astrophysics Data System (ADS)

Hilton, J. L.

2006-08-01

The IAU Working Group on Precession and the Ecliptic was charged with providing a precession model that was both dynamically consistent and compatible with the IAU 2000A nutation model, along with an updated definition and model for the ecliptic. The report of the working group has been accepted for publication in Celestial Mechanics (Hilton et al. 2006, in press) and has resulted in a recommendation to be considered at this General Assembly of the IAU. Specifically, the working group recommends: 1. That the terms lunisolar precession and planetary precession be replaced by precession of the equator and precession of the ecliptic, respectively. 2. That, beginning on 1 January 2009, the precession component of the IAU 2000A precession-nutation model be replaced by the P03 precession theory, of Capitaine et al. (2003, A&A, 412, 567-586) for the precession of the equator (Eqs. 37) and the precession of the ecliptic (Eqs. 38); the same paper provides the polynomial developments for the P03 primary angles and a number of derived quantities for use in both the equinox based and Celestial Intermediate Origin based paradigms. 3. That the choice of precession parameters be left to the user. 4. That the ecliptic pole should be explicitly defined by the mean orbital angular momentum vector of the Earth-Moon barycenter in an inertial reference frame, and this definition should be explicitly stated to avoid confusion with other, older definitions. consistent and compatible with the IAU 2000A nutation model, along consistent and compatible with the IAU 2000A nutation model, along with an updated definition and model for the ecliptic.

While benefits of workplace physical exercise on physical health is well known, little is known about the psychosocial effects of such initiatives. This study evaluates the effect of workplace versus home-based physical exercise on psychosocial factors among healthcare workers. A total of 200 female healthcare workers (Age: 42.0, BMI: 24.1) from 18 departments at three hospitals were cluster-randomized to 10 weeks of: 1) home-based physical exercise (HOME) performed alone during leisure time for 10 min 5 days per week or 2) workplace physical exercise (WORK) performed in groups during working hours for 10 min 5 days per week and up to 5 group-based coaching sessions on motivation for regular physical exercise. Vitality and mental health (SF-36, scale 0-100), psychosocial work environment (COPSOQ, scale 0-100), work- and leisure disability (DASH, 0-100), control- (Bournemouth, scale 0-10) and concern about pain (Pain Catastrophizing Scale, scale 0-10) were assessed at baseline and at 10-week follow-up. Vitality as well as control and concern about pain improved more following WORK than HOME (all p < 0.05) in spite of increased work pace (p < 0.05). Work- and leisure disability, emotional demands, influence at work, sense of community, social support and mental health remained unchanged. Between-group differences at follow-up (WORK vs. HOME) were 7 [95% confidence interval (95% CI) 3 to 10] for vitality, -0.8 [95% CI -1.3 to -0.3] for control of pain and -0.9 [95% CI -1.4 to -0.5] for concern about pain, respectively. Performing physical exercise together with colleagues during working hours was more effective than home-based exercise in improving vitality and concern and control of pain among healthcare workers. These benefits occurred in spite of increased work pace. NCT01921764 at ClinicalTrials.gov . Registered 10 August 2013.

Adverse effects by night-call duty have become an important occupational health issue. The aim of this study was to investigate whether the heart rate variability (HRV) differed during recovery from day work and night-call duty between distinct physician specialities. We studied the impact of a 16-h night-call duty on autonomic balance, measured by HRV, among two physician groups differing with respect to having to deal with life-threatening conditions while on call. Nineteen anaesthesiologists (ANEST) and 16 paediatricians and ear, nose and throat surgeons (PENT) were monitored by ambulatory digital Holter electrocardiogram (ECG). Heart rate variability was analysed between 21:00 and 22:00 after an ordinary workday, on night call and in the evening post-call. Absolute and normalized high-frequency power (HF, HFnu) were the main outcome variables, expressing parasympathetic influence on the heart. ANEST had lower HF power than PENT while on night call and post-daytime work (p < 0.05), but not at post-night call. In the whole group of physicians, HFnu was lower on call and post-daytime work compared with post-night-call duty (p < 0.05). The physiological recovery after night duty seemed sufficient in terms of HRV patterns for HFnu, reflecting autonomic balance and did not differ between specialities. However, the less dynamic HRV after daytime work and during night-call duty in the ANEST group may indicate a higher physiological stress level. These results may contribute to the improvement of night-call schedules within the health care sector.

communication skills represent an essential component of clinical competence. In the field of pediatrics, communication between physicians and patients' parents is characterized by particular difficulties. To investigate the effects of a parent-physician communication skills training program on OSCE performance and self-efficacy in a group control design. parallel to their daily work in the outpatient department, intervention-group experienced clinicians in practice (n=14) participated in a communication training with standardized parents. Control-group physicians (n=14) did not receive any training beyond their daily work. Performance was assessed by independent video ratings of an OSCE. Both groups rated their self-efficacy prior to and following training. regarding OSCE performance, the intervention group demonstrated superior skills in building relationships with parents (p<.024) and tended to perform better in exploring parents' problems (p<.081). The communication training program led to significant improvement in self-efficacy with respect to the specific training objectives in the intervention group (p<.046). even in physicians with considerable experience, structured communication training with standardized parents leads to significant improvement in OSCE performance and self-efficacy. PRACTISE IMPLICATIONS: briefness and tight structure make the presented communication training program applicable even for experienced physicians in daily clinical practice. 2010 Elsevier Ireland Ltd.

Jorgensen, Ben; Williamson, Anne; Chu, Rene; Qian, Fang

2017-06-01

This ex vivo study aimed to evaluate the efficacy of retreating GuttaCore (Dentsply Tulsa Dental Specialties, Tulsa, OK) and warm vertically condensed gutta-percha in moderately curved canals with 2 different systems: ProTaper Universal Retreatment (Dentsply Tulsa Dental) and WaveOne (Dentsply Tulsa Dental). Eighty mesial roots of mandibular molars were used in this study. The mesiobuccal canals in each sample were prepared to length with the WaveOne Primary file (Dentsply Tulsa Dental). The canals were obturated with either a warm vertical approach or with GuttaCore and divided into 4 retreatment groups with the same mean root curvature: warm vertical retreated with ProTaper, warm vertical retreated with WaveOne, GuttaCore retreated with ProTaper, and GuttaCore retreated with WaveOne. The warm vertical groups were obturated using a continuous-wave technique of gutta-percha compaction, and the GuttaCore groups were obturated according to the manufacturer's instructions. After allowing sealer to set, each specimen was retreated with either the ProTaper Universal Retreatment files D1, D2, or D3 or with the WaveOne Primary file to the predetermined working length. The time taken to reach the working length was recorded. Instrument fatigue and failure were also evaluated. The post hoc 2-sample t tests showed that the overall mean total time taken to reach the working length for the warm vertical groups was significantly greater than that observed for the GuttaCore groups (mean = 87.11 vs 60.16 seconds, respectively), and the overall mean total time taken to reach the working length for WaveOne was significantly greater than that observed for ProTaper (99.09 vs 48.18 seconds, respectively). Two-way analysis of variance showed a significant main effect for both the type of experiment groups (F 1,76  = 15.32, P = .0002) and the type of retreatments (F 1,76  = 54.67, P < .0001). Also, the WaveOne Primary file underwent more separations than the ProTaper files. The WaveOne Primary file underwent more separations and was unable to remove gutta-percha as efficiently as the ProTaper Universal Retreatment files. Also, canals obturated with GuttaCore were retreated more efficiently and with fewer file separations than the canals obturated using continuous wave of warm gutta-percha.

Although long working hours have been suspected to be a risk factor for depressive symptoms (DS), it is not well understood the conditions under which long working hours are associated with it. This study investigated the moderating effect of job satisfaction on the relationship between working hours and DS. A total of 2,375 full-time non-shift day workers (73% men), aged 18-79 (mean 45) years, in 296 small- and medium-scale businesses were surveyed using a self-administered questionnaire evaluating working hours, job satisfaction, DS and covariates. The Center for Epidemiologic Studies Depression scale (CES-D) was used to assess DS. Risk of DS (CES-D ≥ 16) by working hours, job satisfaction, and both combined was estimated by multivariable logistic regression analysis. Compared to participants working 6-8 hrs/day, those working 12+ hrs/day had significantly higher odds of DS (adjusted odds ratio [aOR] 1.49), while participants with low satisfaction, as opposed to high satisfaction, had increased odds of DS (aOR 1.81). Furthermore, compared to those working 6-8 hrs/day with high satisfaction (reference group), participants working 6-8 hrs/day, > 8 to 10 hrs/day, and > 10 hrs/day combined with low satisfaction had dose-response increase of DS (aOR 1.48, 2.21 and 2.31, respectively, p < 0.05), whereas those working > 8 to 10 hrs/day and > 10 hrs/day combined with high satisfaction had not (aOR 0.93 and 1.39, respectively, p > 0.10). The results suggest that long working hours are associated with increased risk of DS only under reduced job satisfaction condition, which highlights the importance of improving job satisfaction, particularly among those working excessive hours.

Purpose Employer policies and practices have been shown to impact workplace disability, but research in this area has waned in recent years despite an aging workforce, a growing prevalence of chronic health conditions, and a larger proportion of working-age adults on permanent work disability in many jurisdictions. The purpose of this article is to describe the background rationale and methodology for an invited conference designed to improve research of employer strategies to curtail work disability. Methods A multidisciplinary team of 26 international researchers with published research in employer-based disability management or related fields were invited to attend a 3-day conference in Hopkinton, Massachusetts, USA. The overall goal was to review the status of current research of workplace disability management and prevention, examine its relevance for employer decision-making, compare conceptual frameworks or theoretical perspectives, and recommend future research directions. Working groups were organized and draft manuscripts were prepared in advance. Conference activities included working group presentations and critiques, discussions with a panel of industry consultants and advisors, group interaction and debate, generation of final recommendations, and manuscript revision. Results/Conclusion Six principal domains were established with respect to future research: (a) further elucidation of the key workplace factors that buffer the disabling effects of injury and illness; (b) more innovative and feasible options for workplace intervention; (c) measurement of workplace-relevant disability outcomes; (d) a stronger theoretical framework for understanding the factors behind employer uptake and implementation; (e) a focus on special clinical populations and occupations where disability risk is most troubling; and (f) better representation of workers and employers that reflect the diverse and changing nature of work. Final comments and recommendations of the working groups are presented in the following six articles in this special issue of the Journal of Occupational Rehabilitation. Conference attendees recommended changes in methodology, collaboration strategies, and theoretical perspectives to improve the practical and scientific impact of future research of employer practices.

External biosecurity protocols, aimed at preventing the introduction of new pathogens to the farm environment, are becoming increasingly important in the swine industry. Although assessments at the individual farm level occur regularly, efforts to cluster swine herds into meaningful biosecurity groups and to summarize this information at the regional level are relatively infrequent. The objectives of this study were: (i) to summarize external biosecurity practices on sow farms in southern Ontario; (ii) to cluster these farms into discrete biosecurity groups and to describe their characteristics, the variables of importance in differentiating between these groups, and their geographic distribution; and (iii) to identify significant predictors of biosecurity group membership. Data were collected using the Production Animal Disease Risk Assessment Program's Survey for the Breeding Herd. A subset of variables pertaining to external biosecurity practices was selected for two-step cluster analysis, which resulted in 3 discrete biosecurity groups. These groups were named by the authors as: (i) high biosecurity herds that were open with respect to replacement animals, (ii) high biosecurity herds that were closed with respect to replacement animals, and (iii) low biosecurity herds. Variables pertaining to trucking practices and the source of replacement animals were the most important in differentiating between these groups. Multinomial logistic regression provided insight into which demographic and neighborhood variables serve as significant predictors of biosecurity group membership (p<0.05). Variables in the final regression model include: herd density within a 4.8 km radius, number of sows on the premises, and site production type. The odds of belonging to the high biosecurity group that was open with respect to replacement animals, relative to the low biosecurity group, increased 1.001 times for each additional sow (p=0.001). The odds of belonging to the high biosecurity group that was open with respect to replacement animals, relative to the low biosecurity group, were 6.5 times greater for farms that produced genetic animals than for farms that produced commercial animals (p=0.003). The information obtained through this work allows a better understanding of biosecurity in sow herds at the regional level, and the implementation of biosecurity protocols in North American swine herds in general.

Land use planning is a complex field comprised of legislation, policies, processes and tools. A growing body of evidence supports the relationship between land use planning decisions, community design and health. The built environment has been shown to be associated with physical inactivity, obesity, cardiovascular disease, respiratory disease and mental illness. Consequently, there is a growing interest within public health to work with planners on land use planning initiatives such as official plans and transportation master plans. Two surveys were developed: one for public health professionals and the other for planning professionals (survey questions available upon request to the corresponding author). The surveys were pilot tested in two separate focus group sessions with public health and planning professionals. Focus group volunteers helped to validate the surveys by verifying survey questions, design and overall flow. In early 2012, 304 public health professionals and 301 planning professionals completed the two separate surveys, comprising the total survey respondents for each respective profession used to calculate proportions. The survey results represent a convenience sample and are not generalizable to the entire population of public health and planning professionals in Ontario. Results compare survey responses from both groups where appropriate. Most respondents worked either as public health staff (78%) or planners/senior planners (58%). A smaller percentage of public health and planning professionals worked either as managers (15% and 11%, respectively) or directors (5% and 9%, respectively). Health is associated with how communities are planned and built, and the services and resources provided within them. Inspired by the results of our survey and based on user feedback from the pilot tests, a free online training program entitled "Public Health and Planning 101: An Online Course for Public Health and Planning Professionals to Create Healthier Built Environments" was launched in 2016 by OPHA as a collaborative project with OPPI and PHAC. This course is designed to bridge the gaps between the two professions, as well as provide greater opportunities for developing collaborative partnerships to help create and foster healthy built environments.

Efforts to improve performance in the workplace with respect to positive mental health have increased, and cognitive behavioral therapy (CBT) has recently attracted attention as an intervention measure to this end. Here, we conducted a randomized controlled trial to evaluate the effectiveness of a brief training program on CBT for improving work performance of employees. The participants were employees of an electric company in Japan. The intervention consisted of 1 group session of CBT (120 min) and web-based CBT homework for 1 month. We evaluated employees in both the intervention and control groups at baseline and follow-up after three months. The main outcome was work performance, which was evaluated by a subjective score from 1 to 10. The secondary outcome was self-evaluation of cognitive flexibility. Analyses were conducted based on ITT. In the intervention group, 84 participants attended the group session, with 79 subsequently completing at least 1 instance of online homework. ITT analysis showed that the subjective performance of the intervention group was significantly improved compared with that of the control group (1.47 vs. 0.69, mean difference 0.78 [95% confidence interval {CI}, 0.05 to 1.51], Cohen's d=0.31). The ability to recognize dysfunctional thinking patterns and change them to positive ones significantly improved in the intervention group compared to the control group (0.71 vs. 0.26, mean difference 0.45 [95% CI 0.06 to 0.83], d=0.33). However, after adjustment for baseline scores, no significant difference was observed. The ability to view a situation from multiple perspectives and expand one's repertoire of thought patterns in the intervention group also significantly improved (0.83 vs. 0.35, mean difference 0.48 [95% CI 0.35 to 0.95], d=0.29), but here again, significance was lost after adjusting for baseline scores. Our results suggest that a brief training program that combines a group CBT session with web-based CBT homework improved subjective work performance. In addition, this program might help improve employees' cognitive flexibility.

We compared StrepB Select medium (Select) after enrichment with conventional culture for the detection of Group B Streptococcus (GBS). Postenrichment sensitivities of Select and conventional culture were 98.8% and 92.2%, respectively (P < 0.05). Select was superior for detection of GBS from vaginal-rectal specimens. Growth of non-GBS colonies required additional work to exclude the presence of GBS, especially after 48 h of incubation. Incubation of Select beyond 24 h did not significantly increase the yield of GBS. PMID:20962144

PURPOSE To evaluate the fit of a three-unit metal framework of fixed dental prostheses made by subtractive and additive manufacturing. MATERIALS AND METHODS One master model of metal was fabricated. Twenty silicone impressions were made on the master die, working die of 10 poured with Type 4 stone, and working die of 10 made of scannable stone. Ten three-unit wax frameworks were fabricated by wax-up from Type IV working die. Stereolithography files of 10 three-unit frameworks were obtained using a model scanner and three-dimensional design software on a scannable working die. The three-unit wax framework was fabricated using subtractive manufacturing (SM) by applying the prepared stereolithography file, and the resin framework was fabricated by additive manufacturing (AM); both used metal alloy castings for metal frameworks. Marginal and internal gap were measured using silicone replica technique and digital microscope. Measurement data were analyzed by Kruskal-Wallis H test and Mann-Whitney U-test (α=.05). RESULTS The lowest and highest gaps between premolar and molar margins were in the SM group and the AM group, respectively. There was a statistically significant difference in the marginal gap among the 3 groups (P<.001). In the marginal area where pontic was present, the largest gap was 149.39 ± 42.30 µm in the AM group, and the lowest gap was 24.40 ± 11.92 µm in the SM group. CONCLUSION Three-unit metal frameworks made by subtractive manufacturing are clinically applicable. However, additive manufacturing requires more research to be applied clinically. PMID:29279766

The development of European standard (CEN) methods in support of European Directives for plastics materials and articles intended to come into contact with foodstuff.

PubMed

Ashby, R

1994-01-01

CEC Directives have been implemented for plastics materials and articles intended to come into contact with foodstuffs. These introduce limits upon the overall migration from plastics into food and food simulants. In addition, specific migration limits or composition limits for free monomer in the final article, have been set for some monomers. Agreed test methods are required to allow these Directives to be respected. CEN, the European Committee for Standardization, has created a working group to develop suitable test methods. This is 'Working Group 5, Chemical Methods of Test', of CEN Technical Committee TC 194, Utensils in contact with food. This group has drafted a ten part standard for determining overall migration into aqueous and fatty food simulants by total immersion, by standard cell, by standard pouch and by filling. This draft standard has been approved by CEN TC 194 for circulation for public comment as a provisional standard, i.e. as an ENV. Further parts of this standard are in preparation for determining overall migration at high temperatures, etc. Simultaneously, Working Group 5 is cooperating with the BCR (Community Bureau of Reference) to produce reference materials with certified values of overall migration. CEN TC 194 Working Group 5 is also drafting methods for monomers subject to limitation in Directive 90/128/EEC. Good progress is being made on the monomers of highest priority but it is recognized that developing methods for all the monomers subject to limitation would take many years. Therefore, collaboration with the BCR, the Council of Europe and others is taking place to accelerate method development.

To evaluate the predictive value of the Work Ability Index (WAI) for different indicators of the need for rehabilitation at 1-year follow-up. Cohort study. Data were obtained from the Second German Sociomedical Panel of Employees, a large-scale cohort study with postal surveys in 2009 and 2010. A total of 457 women and 579 men were included. Confirmatory factor analysis confirmed the one-dimensionality of the WAI. Regression analyses showed that poor and moderate baseline WAI scores were associated with lower health-related quality of life and more frequent use of primary healthcare 1 year later. Subjects with poor baseline work ability had 4.6 times higher odds of unemployment and 12.2 times higher odds of prolonged sick leave than the reference group with good or excellent baseline work ability. Moreover, the odds of subjectively perceived need for rehabilitation, intention to request rehabilitation and actual use of rehabilitation services were 9.7, 5.7 and 3 times higher in the poor baseline WAI group and 5.5, 4 and 1.8 times higher in the moderate baseline WAI group, respectively. A WAI score ≤ 37 was identified as the optimal cut-off to predict the need for rehabilitation. The WAI is a valid screening tool for identifying the need for rehabilitation.

Since NASA began human presence on the International Space Station (ISS) in November 1998, crews have spent two to seven months onboard. In March 2015 NASA and Russia embarked on a new era of ISS utilization, with two of their crewmembers conducting a one-year mission onboard ISS. The mission has been useful for both research and mission operations to better understand the human, technological, mission management and staffing challenges that may be faced on missions beyond Low Earth Orbit. The work completed during the first 42 ISS missions provided the basis for the pre-flight, in-flight and post-flight work completed by NASA's Space Medicine Operations Division, while our Russian colleagues provided valuable insights from their long-duration mission experiences with missions lasting 10-14 months, which predated the ISS era. Space Medicine's Behavioral Health and Performance Group (BHP) provided pre-flight training, evaluation, and preparation as well as in-flight psychological support for the NASA crewmember. While the BHP team collaboratively planned for this mission with the help of all ISS international partners within the Human Behavior and Performance Working Group to leverage their collective expertise, the US and Russian BHP personnel were responsible for their respective crewmembers. The presentation will summarize the lessons and experience gained within the areas identified by this Working Group as being of primary importance for a one-year mission.

To describe the survey methodology and initial general findings of the first Central American Survey of Working Conditions and Health. A representative sample of 12,024 workers was interviewed at home in Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and Panama. Questionnaire items addressed worker demographics, employment conditions, occupational risk factors and self-perceived health. Overall, self-employment (37%) is the most frequent type of employment, 8% of employees lack a work contract and 74% of the workforce is not covered by social security. These percentages are higher in Guatemala, Honduras and El Salvador, and lower in Costa Rica, Panama and Nicaragua. A third of the workforce works more than 48 h per week, regardless of gender; this is similar across countries. Women and men report frequent or usual exposures to high ambient temperature (16% and 25%, respectively), dangerous tools and machinery (10%, 24%), work on slippery surfaces (10%, 23%), breathing chemicals (12.1%, 18%), handling toxic substances (5%, 12.1%), heavy loads (6%, 20%) and repetitive movements (43%, 49%). Two-thirds of the workforce perceive their health as being good or very good, and slightly more than half reports having good mental health. The survey offers, for the first time, comparable data on the work and health status of workers in the formal and informal economy in the six Spanish-speaking Central American countries, based on representative national samples. This provides a benchmark for future monitoring of employment and working conditions across countries. Published by the BMJ Publishing Group Limited.

Low plasma potassium (K) and depletion of K can occur simply through a reduction of K intake and are associated with increased risk of VF. The K-status of the populations was evaluated in the NE (Group 1, n=30), Bangkok (Group 2, n=48) and Singapore (Group 3, n=46). Groups 2 and 3 were further subdivided into Group 2A (worked in Bangkok < or = 1 year, n=8), Group 2B (worked in Bangkok > 1 year, n=40), Group 3A (consumed self-prepared or ready-to-buy meals, n=25) and Group 3B (regularly consumed foods provided free-of-charge by construction companies, n=21). Thirty-four male healthy university personnels from the NE and Bangkok served as the control--Group 4. Two 24-h urine samples and a fasting blood sample were collected from each subject. Dietary-K from food was determined by duplicated meal analysis. All these samples were then analyzed for their K-content. Group 3A had the lowest K-status: their K-intake, serum-K, and urinary-K level were 29 +/- 5.8 mmol/day (% low K-intake=100), 3.43 +/- 0.34 mmol/L (% hypokalemia=48) and 19.23 +/- 8.2 mmol/day (% hypokaliuria=87.5), respectively. Among the construction workers, average K-intake, serum-K and urinary-K levels were 45.5 +/- 6.1 mmol/day (% low K-intake = 37.5), 3.93 +/- 0.2 mmol/L (% hypokalemia = 2.5) and 39.6 +/- 9.2 mmol/day (% hypokaliuria = 12.5), respectively. The values of Group 2B were similar to Group 4. In addition, when the data from all of the groups were compared, there was a positive correlation between dietary-K (intake) and urinary-K (excretion) (r=0.881, p<0.001). In conclusion, NE Thailand constructors from various locations exhibited low K status with low dietary-K, high incidence of hypokalemia, and low urinary-K. From the present study, this low K status may be an important trigger factor for VF in construction workers and associated with increase risk of SUDS.

A 15-year research conducted in USA showed that compensation expenses paid to workers for musculoskeletal disorders (MSDs) of back exceeded 128 million Dollars calculated on the basis of 0.97 Dollars per hour of work. In addition, according to the latest studies carried out in relation with disease burdens with risk factors in Iran, DALYs indices for low back pain, knee arthrosis and other musculoskeletal disorders have been reported to be 307772, 291305 and 872633 respectively, which have caused the work related diseases to occupy the second position in the country, after cardiovascular diseases. On the other hand, in accordance with occupational health indices of Iranian health ministry, 37% of all working population had had poor work postures with 15% of all working population had been working with inappropriate working tools in the year 2009. This was a case study comparing exposed workers with control group using Standard Nordic Questionnair in sewing machine operators of a shoe manufacturing factory in Iran. In this study, the mentioned questionnaires were filled out for the exposed group (25 sewing machine operators with average age of 43.5 years with work records of 16.8 years) and control group (15 employees from administrative department with average age of 39.8 years with work records of 13.4 years) which both were selected through simple random method. There were statistically significant differences in age between musculoskeletal disorders of right elbow (p = 0.033), thigh (p = 0.044), both knees (p = 0.019) and ankles (p = 0.039). There were also statistically significant association between gender and musculoskeletal disorders of right elbow (p = 0.028), thigh (p = 0.026) both knees (p = 0.011); right shoulder disorders (p = 0.018) and work records; disorders of both knees (p = 0.031) and number of cigarettes smoked. In general, prevalence of disorders of cervical area, shoulders with hands, vertebral column, back, knees, thigh with feet were higher in exposed group due to poor work posture. Meanwhile, female workers were inflicted more than males. On the other hand, these disorders were seen more with increased work records and age in which, improvement of work postures, training for better execution of tasks and conducting periodic screening tests are being recommended.

Career preferences and the work-family balance in medicine: gender differences among medical specialists.

In this article career preferences of medical specialists in the Netherlands are analysed, based on a survey among the members of medical associations of five specialties. Four different career preferences were offered, each of which implied a possible variation in working hours. A questionnaire was sent to a random selected group of working specialists in general practice, internal medicine, anaesthesiology, ophthalmology and psychiatry. Logistic regressions were used to predict career preferences. Besides individual characteristics, work and home domain characteristics were taken into the analysis. Not surprisingly, the preference for career change in respect of working hours is higher among full-time MDs, especially women, than among part-time workers. In contradiction to what was expected, home domain characteristics did not predict a part-time preference for female, but for male MDs. One home domain characteristic, children's age, did predict the male part-time preference. Further gender differences were found in respect of the fit between actual and preferred working hours (A/P-fit). The majority of male MDs with a full-time preference had achieved an A/P-fit, whereas significantly less female MDs achieved their preferences. It was found that hospital-bound specialists are less positive towards part-time careers than other specialists. Furthermore, the change of working hours would imply a reduction in FTE for all specialties, if all preferences were met. Especially in hospital-bound specialisms it was not confirmed that the reduction in FTE would be low; this was found only in respect of interns. It may be concluded that individual preferences in career paths are very diverse. Personnel policy in medical specialties, especially in hospitals, will have to cope with changes in traditional vertical and age-related career paths. Flexible careers related to home domain determinants or other activities will reinforce a life cycle approach, in which the centrality of work is decreasing.

This study reports the design, implementation, and evaluation of a program attempting to reduce job stress by improving person-environment fit with respect to job aspects such as work load, responsibility, and interpersonal relationships. In order to assess the effects of the program, measures of both stress and strain were collected at three points in time--just prior to the program, immediately after the program, and three months after completion of the program. Measures of strain included systolic and diastolic blood pressure, determinations of glucose, cholesterol, and uric acid in the plasma, job satisfaction, and job related self-esteem. The findings were interpreted in light of both program incidents within specific experimental groups and general aspects of the program common to the experimental groups. Additional analyses indicated that both good person-environment fit with respect to participation predicts to good fit with respect to other job aspects over a three month interval and that stress causes strain, rather than the reverse.

The aim of this work is to establish the relationship between the morphology of Intracytoplasmic Morphologically Selected Sperm Injection (IMSI)-selected spermatozoa and their DNA integrity. The 45 ejaculates were randomly distributed into three treatment groups: normozoospermic, oligoasthenozoospermic and oligoasthenotheratozoospermic samples. The evaluation of DNA integrity was performed using the sperm chromatin dispersion test. It was established that DNA integrity of spermatozoa is strongly dependent on ejaculate quality (P < 0.05). The count of spermatozoa with nonfragmented DNA in normozoospermic samples was high and independent from IMSI-morphological classes (Class 1 versus Class 3, respectively) (P > 0.1). With decreased ejaculate quality, the percentage of spermatozoa with nonfragmented DNA decreased significantly (P < 0.05) independent from morphological class. Nevertheless, the rate of IMSI-selected spermatozoa with fragmented DNA within of Class 1 in normozoospermic (Group 1), in oligoasthenozoospermic (Group 2) and in oligoasthenotheratozoospermic (Group 3) samples was 21.1%, 31.8% and 54.1%, respectively. In conclusion, there is a direct relationship between morphological parameters of spermatozoa and their DNA integrity. However, the IMSI technique alone is not enough for the selection of spermatozoa with intact nuclei. © 2013 Blackwell Verlag GmbH.

We compared the efficiency, side effects and effects on spermatogenesis of sclerotherapy with phenol and surgical treatment for hydrocele. A total of 67 patients (80 hydroceles) were randomly divided into 2 groups of 40 hydroceles each. One group underwent phenol sclerotherapy and the other underwent hydrocelectomy. Spermiograms were done before, 6 and 12 months after treatment in patients able to ejaculate. In the sclerotherapy group 47.5%, 30%, 12.5%, 5% and 2.5% of the hydroceles were cured with 1 to 5 injections, respectively, but 2.5% were not cured even with 6 injections. There were no complaints of localized pain or infection in these cases. All patients returned to normal activity on the same day. In the hydrocelectomy group 97.5% and 2.5% of hydroceles were cured with 1 and 2 operations, respectively. There was pain postoperatively in 73.5% of the patients and localized infection in 5%, while 62.5% required an average of 4.5 days of rest and were absent from work for 10 days. There was no significant statistical alteration in spermatozoid concentration in the preoperative, and 6 and 12-month postoperative counts in the groups (p = 0.385). Sclerotherapy for hydrocele with phenol is as efficacious as hydrocelectomy, while causing less morbidity and similar effects on spermatogenesis.

Abstract The aim of this study was to determine differences in glycolytic metabolite concentrations and work output in response to an all-out interval training session in 23 cyclists with at least 2 years of interval training experience (E) and those inexperienced (IE) in this form of training. The intervention involved subsequent sets of maximal intensity exercise on a cycle ergometer. Each set comprised four 30 s repetitions interspersed with 90 s recovery periods; sets were repeated when blood pH returned to 7.3. Measurements of post-exercise hydrogen (H+) and lactate ion (LA-) concentrations and work output were taken. The experienced cyclists performed significantly more sets of maximal efforts than the inexperienced athletes (5.8 ± 1.2 vs. 4.3 ± 0.9 sets, respectively). Work output decreased in each subsequent set in the IE group and only in the last set in the E group. Distribution of power output changed only in the E group; power decreased in the initial repetitions of set only to increase in the final repetitions. H+ concentration decreased in the third, penultimate, and last sets in the E group and in each subsequent set in the IE group. LA- decreased in the last set in both groups. In conclusion, the experienced cyclists were able to repeatedly induce elevated levels of lactic acidosis. Power output distribution changed with decreased acid–base imbalance. In this way, this group could compensate for a decreased anaerobic metabolism. The above factors allowed cyclists experienced in interval training to perform more sets of maximal exercise without a decrease in power output compared with inexperienced cyclists. PMID:28149346

Our previous work demonstrated that abacus-based mental calculation (AMC), a traditional Chinese calculation method, could help children improve their math abilities (e.g. basic arithmetical ability) and executive function (e.g. working memory). This study further examined the effects of long-term AMC training on math ability in visual-spatial domain and the task switching component of executive function. More importantly, this study investigated whether AMC training modulated the relationship between math abilities and task switching. The participants were seventy 7-year-old children who were randomly assigned into AMC and control groups at primary school entry. Children in AMC group received 2-hour AMC training every week since primary school entry. On the contrary, children in the control group had never received any AMC training. Math and task switching abilities were measured one year and three years respectively after AMC training began. The results showed that AMC children performed better than their peers on math abilities in arithmetical and visual-spatial domains. In addition, AMC group responded faster than control group in the switching task, while no group difference was found in switch cost. Most interestingly, group difference was present in the relationships between math abilities and switch cost. These results implied the effect of AMC training on math abilities as well as its relationship with executive function. PMID:26444689

A hypersonic transport aircraft design project was selected as a result of interactions with NASA Lewis Research Center personnel and fits the Presidential concept of the Orient Express. The Graduate Teaching Assistant (GTA) and an undergraduate student worked at the NASA Lewis Research Center during the 1986 summer conducting a literature survey, and relevant literature and useful software were collected. The computer software was implemented in the Computer Aided Design Laboratory of the Mechanical and Aerospace Engineering Department. In addition to the lectures by the three instructors, a series of guest lectures was conducted. The first of these lectures 'Anywhere in the World in Two Hours' was delivered by R. Luidens of NASA Lewis Center. In addition, videotaped copies of relevant seminars obtained from NASA Lewis were also featured. The first assignment was to individually research and develop the mission requirements and to discuss the findings with the class. The class in consultation with the instructors then developed a set of unified mission requirements. Then the class was divided into three design groups (1) Aerodynamics Group, (2) Propulsion Group, and (3) Structures and Thermal Analyses Group. The groups worked on their respective design areas and interacted with each other to finally come up with an integrated conceptual design. The three faculty members and the GTA acted as the resource persons for the three groups and aided in the integration of the individual group designs into the final design of a hypersonic aircraft.

Wellbeing is one's evaluation and judgment of one's life. It consists of 3 dimensions: positive affectivity, negative affectivity, and life satisfaction. This study aimed to compare the subjective wellbeing and positive future expectations between working and nonworking adolescents. The study was designed as descriptive and comparative. The study sample consisted of 420 working and 482 nonworking adolescents (n = 902) aged 15 - 20 years, who were randomly recruited from two occupational education centers in Istanbul, Turkey and two high schools (formal educations) in the same district. Adolescent subjective wellbeing scale (ASWS) total mean (SD) scores for working adolescents and nonworking adolescents were 48.76 (9.50) and 49.72 (8.01), respectively. In addition, positive future expectations scale (PFES) total mean (SD) scores for working adolescents and nonworking adolescents were 18.71 (4.50) and 19.06 (3.49), respectively. In this study, no significant difference was found between the general wellbeing (scale total median score) scores of the working and nonworking adolescent groups (Z = 1.01, P = 0.315). However, significant differences were found in the family relations satisfaction (Z = 3.23, P = 0.002) and relations with significant others (Z = 2.85, P = 0.004) subscales of the ASWS. A positive relationship was found between adolescent subjective wellbeing and positive future expectations. It was found that nonworking adolescents scored higher on the dimensions of "family relations" and "relations with significant others" of subjective wellbeing compared to those dimensions in working adolescents.

In South Korea, the number of workers suffering from mental illnesses, such as depression, has rapidly increased. There is growing concern about depressive symptoms being associated with both working conditions and psychosocial environmental factors. To investigate potential psychosocial environmental moderators in the relationship between working conditions and occupational depressive symptoms among wage workers. Data were obtained from the wage worker respondents (n = 4,095) of the Korean National Health and Nutrition Examination Survey of 2009. First, chi-square tests confirmed the differences in working conditions and psychosocial characteristics between depressive and non-depressive groups. Second, multivariate logistic regression analysis was performed to examine the moderating effects of the psychosocial environmental factors between working conditions and depressive symptoms. After adjusting for potential covariates, the likelihood of depressive symptomatology was high among respondents who had dangerous jobs and flexible work hours compared to those who had standard jobs and fixed daytime work hours (OR = 1.66 and 1.59, respectively). Regarding psychosocial factors, respondents with high job demands, low job control, and low social support were more likely to have depressive symptoms (OR = 1.26, 1.58 and 1.61, respectively). There is a need to develop non-occupational intervention programs, which provide workers with training about workplace depression and improve social support, and the programs should provide time for employees to have active communication. Additionally, companies should provide employees with support to access mental healthcare thereby decreasing the occurrence of workplace depression.

The purpose of this study was to determine the personal factors and working conditions that predict work injuries among industrial workers. To fulfill this aim, a case control study was conducted including 2003 industrial workers who sustained a work injury and an equal number of controls. All were subjected to an interview questionnaire to collect relevant information. Moreover, records were reviewed to obtain the medical history of enrolled workers. Data revealed that workers in the index and control groups are comparable in respect to their sociodemographic characteristics. The multivariate logistic regression analysis pointed out that safety training significantly reduces the risk of work accidents among industrial workers. On the other hand, work accidents are more likely to occur in the main working shift. Moreover, workers who suffer from chronic health problems calling for surgical treatment, as well as those who reported family problems, are more likely to experience work accidents. These workers should receive considerable attention to reduce the extent of work injuries. More importantly, safety-training programs are mandatory for accident prevention in industrial settings.

The aim of this work was to evaluate the clinical efficacy and safety of simultaneous integrated boost-intensity modulated radiation therapy (SIB-IMRT) in patients with inoperable hepatocellular carcinoma (HCC). A total of 53 patients with inoperable HCC underwent SIB-IMRT using two dose-fractionation schemes, depending on the proximity of gastrointestinal structures. The 41 patients in the low dose-fractionation (LD) group, with internal target volume (ITV) < 1 cm from gastrointestinal structures, received total doses of 55 and 44 Gy in 22 fractions to planning target volume 1 (PTV1) and 2 (PTV2), respectively. The 12 patients in the high dose-fractionation (HD) group, with ITV ≥ 1 cm from gastrointestinal structures, received total doses of 66 and 55 Gy in 22 fractions to the PTV1 and PTV2, respectively. Overall, treatment was well tolerated, with no grade > 3 toxicity. The LD group had larger sized tumors (median: 6 vs. 3.4 cm) and greater frequencies of vascular invasion (80.6 vs. 16.7 %) than patients in the HD group (p < 0.05 each). The median overall survival (OS) was 25.1 mKonzept ist machbar und sicheronths and the actuarial 2-year local progression-free survival (LPFS), relapse-free survival (RFS), and OS rates were 67.3, 14.7, and 54.7  %, respectively. The HD group tended to show better tumor response (100 vs. 62.2 %, p = 0.039) and 2-year LPFS (85.7 vs. 59  %, p = 0.119), RFS (38.1 vs. 7.3 %, p = 0.063), and OS (83.3 vs. 44.3 %, p = 0.037) rates than the LD group. Multivariate analysis showed that tumor response was significantly associated with OS. SIB-IMRT is feasible and safe for patients with inoperable HCC.

To understand the HIV infection status among MSM in Hubei province and provide scientific evidence for the development of intervention strategy. A total of 11 438 samples were collected from MSM in sentinel surveillance during 2010-2013 to detect HIV-1 antibody. BED-CEIA was used to identify the recent HIV infection, and the recent HIV infection rate among the MSM was estimated. The age, group and area specific recent infection rate and condom use rate were analyzed. The annual HIV positive rates among MSM were 3.34% , 3.74% , 2.96% and 3.15% respectively and the annual recent infection rates were 2.31% , 1.91% , 1.53% and 1.71% respectively during 2010-2013. The HIV positive rate in age group ≤ 30 years was lower than that in age group >30 years, but the recent HIV incidence rate was higher in age group ≤ 30 years than in age group >30 years. The detection rate of recent HIV infection varied with sample source, the highest detection rate was among the samples form work group/CDC and public bathroom (3.54% and 3.49%, respectively). The recent HIV i nfection rate in Wuhan was highest (5.73%). The proportion of MSM using condoms in each homosexual behavior during past six months was 38.91% . Multiple logistic regression analysis indicated that the factors related to recent HIV infection included sample source (OR = 0.344-0.713), area (OR = 3.581-9.577) and condom usage (OR = 6.686). The HIV-1 infection rate in MSM was at a high level in Hubei, especially in some areas. The condom use rate was low, it is necessary to strengthen the prevention and control of HIV infection in MSM.

Public health nurses (PHNs) working in Well Baby Clinic in Israel's Haifa district were voicing great distress to inspectors-the impossibility of meeting their workload, feeling overwhelmed, poor physical, and technological conditions. They were feeling tired and frustrated and burn-out was rising. The district's nursing management took the decision, together with Tel Aviv University's nursing research unit, to conduct a quality improvement project based on issues that arose from meetings with focus groups on the nurses' difficulties. This paper is a case study of a quality improvement project targeting nurses daily working life. One of its chief contributions is as a study of meeting PHNs' frustration by integrating focus groups and round-table brainstorming (involving nurses, clinic managers and nursing inspectors) in order to identify targets for practical intervention. This strategy has been very successful. It has provided the district's nursing management a battery of forcefully argued and realistically grounded proposals for making the work of Well Baby clinics more relevant to their communities and giving nurses (a) the conditions to meet their assignments and (b) greater professional self-respect. © 2016 Wiley Periodicals, Inc.

Biosurfactant screening was made among the eight halophilic bacterial genera isolated from Kovalam solar salt works in Kanyakumari of India. After initial screening, Kocuria sp. (Km), Kurthia sp. (Ku) and Halococcus sp. (Hc) were found to have positive biosurfactant activity. Biosurfactant derived from Kocuria sp. emulsified more than 50% of the crude oil, coconut oil, sunflower oil, olive oil and kerosene when compared to the other strains. Further, Kocuria marina BS-15 derived biosurfactant was purified and characterized by TLC, FTIR and GC–MS analysis. The TLC analysis revealed that, the purified biosurfactants belong to the lipopeptide group. The IR spectrum results revealed that functional groups are R2C 000000000000 000000000000 000000000000 111111111111 000000000000 111111111111 000000000000 000000000000 000000000000 NN, alkenes and N–H.

To delineate the effect of chronic electromagnetic field (EMF) exposure from radar on plasma melatonin and serotonin levels in occupationally exposed military personnel. A total of 166 male military personnel participated in the study out of which only 155 joined for blood draw. They were divided into three sets: Control group (n = 68), exposure group I (n = 40) exposed to 8-12 GHz and exposure group II (n = 58) working with radar at 12.5-18 GHz frequency. The three groups were further split into two groups according to their years of service (up to 10 years and > 10 years) in order to investigate the effect of years of exposure from radar. Melatonin and serotonin levels were estimated by enzyme immunoassay in fasting blood samples collected from 06:00-07:00 h. EMF measurements were recorded at different locations using Satimo EME Guard 'Personal Exposure Meter' and Narda 'Broad Band Field Meter'. The group I exposed population registered a minor though not significant decrease in plasma melatonin concentration while the other group II exposed population registered statistically significant decline in melatonin concentration when compared with controls. Highly significant increase in plasma serotonin levels was found in exposure group II when compared to control whereas marginal non-significant rise was also registered in exposure group I in comparison to control. Exposure in terms of length of service up to 10 years did not produce any significant effect in the indoleamine levels in both the exposure groups when they were compared with their respective control groups. Whereas, length of service greater than 10 years was observed to decrease and increase respectively the melatonin and serotonin concentration significantly in exposure group II but not in exposure group I. However, correlation test did not yield any significant association between years of service and melatonin or serotonin levels respectively in both the exposure sets I and II. No significant association was observed between melatonin and serotonin levels as well. The study showed the EMF ability to influence plasma melatonin and serotonin concentration in radar workers, significantly in 12.5-18 GHz range with service period greater than 10 years.

Brain activity related to working memory for temporal order and object information.

Maintaining items in an appropriate sequence is important for many daily activities; however, remarkably little is known about the neural basis of human temporal working memory. Prior work suggests that the prefrontal cortex (PFC) and medial temporal lobe (MTL), including the hippocampus, play a role in representing information about temporal order. The involvement of these areas in successful temporal working memory, however, is less clear. Additionally, it is unknown whether regions in the PFC and MTL support temporal working memory across different timescales, or at coarse or fine levels of temporal detail. To address these questions, participants were scanned while completing 3 working memory task conditions (Group, Position and Item) that were matched in terms of difficulty and the number of items to be actively maintained. Group and Position trials probed temporal working memory processes, requiring the maintenance of hierarchically organized coarse and fine temporal information, respectively. To isolate activation related to temporal working memory, Group and Position trials were contrasted against Item trials, which required detailed working memory maintenance of visual objects. Results revealed that working memory encoding and maintenance of temporal information relative to visual information was associated with increased activation in dorsolateral PFC (DLPFC), and perirhinal cortex (PRC). In contrast, maintenance of visual details relative to temporal information was characterized by greater activation of parahippocampal cortex (PHC), medial and anterior PFC, and retrosplenial cortex. In the hippocampus, a dissociation along the longitudinal axis was observed such that the anterior hippocampus was more active for working memory encoding and maintenance of visual detail information relative to temporal information, whereas the posterior hippocampus displayed the opposite effect. Posterior parietal cortex was the only region to show sensitivity to temporal working memory across timescales, and was particularly involved in the encoding and maintenance of fine temporal information relative to maintenance of temporal information at more coarse timescales. Collectively, these results highlight the involvement of PFC and MTL in temporal working memory processes, and suggest a dissociation in the type of working memory information represented along the longitudinal axis of the hippocampus.

With respect to cooperative learning, one aspect of particular interest to educators is its inclusive nature in terms of ensuring that all team members in group work are more or less equally involved in the task. Despite the inherent relevance for second language teaching, however, research is scant. To contribute to this area, the present study…

Two efferent feedback pathways to the auditory periphery may play a role in monitoring self-vocalization: the middle-ear acoustic reflex (MEAR) and the medial olivocochlear bundle (MOCB) reflex. Since most studies regarding the role of auditory efferent activity during self-vocalization were conducted in animals, human data are scarce. The working premise of the current study was that selective mutism (SM), a rare psychiatric disorder characterized by consistent failure to speak in specific social situations despite the ability to speak normally in other situations, may serve as a human model for studying the potential involvement of auditory efferent activity during self-vocalization. For this purpose, auditory efferent function was assessed in a group of 31 children with SM and compared to that of a group of 31 normally developing control children (mean age 8.9 and 8.8 years, respectively). All children exhibited normal hearing thresholds and type A tympanograms. MEAR and MOCB functions were evaluated by means of acoustic reflex thresholds and decay functions and the suppression of transient-evoked otoacoustic emissions, respectively. Auditory afferent function was tested by means of auditory brainstem responses (ABR). Results indicated a significantly higher proportion of children with abnormal MEAR and MOCB function in the SM group (58.6 and 38%, respectively) compared to controls (9.7 and 8%, respectively). The prevalence of abnormal MEAR and/or MOCB function was significantly higher in the SM group (71%) compared to controls (16%). Intact afferent function manifested in normal absolute and interpeak latencies of ABR components in all children. The finding of aberrant efferent auditory function in a large proportion of children with SM provides further support for the notion that MEAR and MOCB may play a significant role in the process of self-vocalization. © 2013 S.

The French Working Group on Perioperative Haemostasis (GIHP) and the French Study Group on Haemostasis and Thrombosis (GFHT) in collaboration with the French Society for Anaesthesia and Intensive Care Medicine (SFAR) drafted up-to-date proposals for the management of antiplatelet therapy in patients undergoing elective invasive procedures. The proposals were discussed and validated by a vote; all proposals but one could be assigned with a high strength. The management of antiplatelet therapy is based on their indication and the procedure. The risk of bleeding related to the procedure can be divided into high, moderate and low categories depending on the possibility of performing the procedure in patients receiving antiplatelet agents (none, monotherapy and dual antiplatelet therapy respectively). If discontinuation of antiplatelet therapy is indicated before the procedure, a last intake of aspirin, clopidogrel, ticagrelor and prasugrel 3, 5, 5 and 7 days before surgery respectively is proposed. The thrombotic risk associated with discontinuation should be assessed according to each specific indication of antiplatelet therapy and is higher for patients receiving dual therapy for coronary artery disease (with further refinements based on a few well-accepted items) than for those receiving monotherapy for cardiovascular prevention, for secondary stroke prevention or for lower extremity arterial disease. These proposals also address the issue of the potential role of platelet functional tests and consider management of antiplatelet therapy for regional anaesthesia, including central neuraxial anaesthesia and peripheral nerve blocks, and for coronary artery surgery.

This study assessed the association between sarcopenia (using the definition of the European Working Group on Sarcopenia in Older People) and fall in the past year among community-dwelling Japanese elderly. Subjects were 1110 community-dwelling Japanese aged 65 or older. We used bioelectrical impedance analysis (BIA) to measure muscle mass, grip strength to measure muscle strength, and usual walking speed to measure physical performance in a baseline study. "Sarcopenia" was characterized by low muscle mass and low muscle strength or low physical performance. "Presarcopenia" was characterized only by low muscle mass. Subjects who did not have any of these deficiencies were classified as "normal." We then administered a questionnaire assessing age, sex, household status, chronic illness, lifestyle-related habits, and fall. This study showed the prevalence of fall was 16.9% and 21.3% in men and women, respectively, while that of sarcopenia was 13.4% and 14.9% in men and women, respectively. In men and women, the prevalence of sarcopenia was higher among those who had fallen. A logistic regression analysis using age, body fat, current drinker status, and physical inactivity for men, and age, body fat, smoking, and diabetes for women as covariate variables revealed that sarcopenia was significantly associated with a history of fall. The odds ratio for fall in the sarcopenia group relative to the normal group was 4.42 (95%CI 2.08-9.39) in men and 2.34 (95%CI 1.39-3.94) in women. This study revealed sarcopenia to be associated with falling in elderly Japanese. Sarcopenia prevention interventions may help prevent falls among elderly individuals.

Physical training is an optimal method of rehabilitation of cardiovascular patients, especially in patients with myocardial infarction. The aim of this study was to evaluate the effects of physical training in patients with myocardial infarction during the post-hospital phase and prolonged rehabilitation by determining the test exercise parameters. This prospective clinical study included 230 patients after myocardial infarction. Group A (180 patients) participated in organized forms of exercise (post-hospital rehabilitation and prolonged rehabilitation at home) for 48 +/- 6.4 months, while the control group was without physical training. The first clinical examination and the exercise test were performed in group A after post-hospital rehabilitation and after 191 +/- 16.4 days in the control group. In all patients the last control was performed 48 +/- 6.4 months after myocardial infarction. After the first control, the mean physical workload in group A was significantly higher compared with the control group (p < 0.05). After a 48 month follow-up period the physical workload was significantly higher in group A (p < 0.01), while in the control group a significant increase of workload was not observed (p > 0.05). Comparing the duration of exercise testing, significant differences were found after the first and last control (p < 0.05; p < 0.01, respectively). The double product was significantly higher in group A than in the control group after the first and last control (p < 0.05; p < 0.01, respectively). Prolonged physical training is beneficial for patients after myocardial infarction, because it improves cardiovascular functions and physical work capacity, improves angina threshold and the patient's general health.

The aim of this work was to evaluate the efficiency of IVF and intracytoplasmic sperm injection (ICSI) when few eggs available for insemination. A total of 601 women (group A, mean age 31.2 +/- 2.8 years) who were undergoing a total of 671 assisted reproduction cycles donated their excess oocytes to 694 patients (group B, mean age 41.0 +/- 0.2) for 1606 replacement cycles. Each recipient received three to five eggs. The recipients were divided into two groups depending on the insemination method used (IVF, group B1; or ICSI, group B2); ICSI patients were then subdivided into two further groups based on the semen parameters: B2A adequate for IVF and B2B only suitable for ICSI. The results showed that, when comparing A versus B and B1 versus B2, no significant differences were found in terms of pregnancy (28.0 versus 24.1% and 25.5 versus 21.4%), implantation (15.6 versus 14.9% and 15.9 versus 13.1%) and miscarriage (15.4 versus 20.5% and 17.9 versus 26.3) rates respectively. Comparing subgroups B2A and B2B, no significant differences were found in terms of pregnancy (20.0 versus 21.9%), implantation (14.4 versus 12.7%) and miscarriage rates (18.2 versus 28.6%) respectively. In conclusion, ICSI does not seem to yield better outcomes.

This paper aims to identify gender similarities and differences in psychosocial work characteristics for those in and out of paid employment, to inform research on possible health-related effects. Specifically five questions are addressed: do women report poorer work characteristics than men; are gender differences related to specific characteristics; do work characteristics differ between full- and part-time women workers and between those in paid and unpaid work; are socio-economic gradients in work characteristics similar for men and women; and, if there are gradients, do they differ between women in paid and unpaid work? Analyses are based on the 33 year follow-up of the 1958 British birth cohort. Four psychosocial work characteristics were examined: learning opportunities, monotony, pace of work, and flexibility of breaks. Women reported more negative work characteristics than men, primarily because of differences in learning opportunities (26% lacked opportunity compared with 13% of men) and monotonous work (47 and 31% respectively). Women in full-time employment reported fewer negative characteristics (27%) than part-time (39%) or home-workers (36%). Home-workers had fewer opportunities for learning (36%) and greater monotony (49%) than paid workers (21 and 22% respectively), however fewer home-workers reported inability to control the work pace (11% compared to 23%) and inflexibility of breaks (21% compared to 47%). Socio-economic gradients in work characteristics were similar among men and women, except for flexibility of break times. A socio-economic gradient in work characteristics was found for full- and part-time workers, but not among home-workers. Differences in self reported health were also examined: a social gradient was found for all employment status groups, being strongest for home-workers despite the absence of a gradient in negative work characteristics. In conclusion, these marked gender differences in psychosocial work characteristics need to be considered in future research on work and health.

In this paper, an approach to biometric verification based on human body communication (HBC) is presented for wearable devices. For this purpose, the transmission gain S21 of volunteer’s forearm is measured by vector network analyzer (VNA). Specifically, in order to determine the chosen frequency for biometric verification, 1800 groups of data are acquired from 10 volunteers in the frequency range 0.3 MHz to 1500 MHz, and each group includes 1601 sample data. In addition, to achieve the rapid verification, 30 groups of data for each volunteer are acquired at the chosen frequency, and each group contains only 21 sample data. Furthermore, a threshold-adaptive template matching (TATM) algorithm based on weighted Euclidean distance is proposed for rapid verification in this work. The results indicate that the chosen frequency for biometric verification is from 650 MHz to 750 MHz. The false acceptance rate (FAR) and false rejection rate (FRR) based on TATM are approximately 5.79% and 6.74%, respectively. In contrast, the FAR and FRR were 4.17% and 37.5%, 3.37% and 33.33%, and 3.80% and 34.17% using K-nearest neighbor (KNN) classification, support vector machines (SVM), and naive Bayesian method (NBM) classification, respectively. In addition, the running time of TATM is 0.019 s, whereas the running times of KNN, SVM and NBM are 0.310 s, 0.0385 s, and 0.168 s, respectively. Therefore, TATM is suggested to be appropriate for rapid verification use in wearable devices. PMID:28075375

Exploration of a 'double-jeopardy' hypothesis within working memory profiles for children with specific language impairment.

PubMed

Briscoe, J; Rankin, P M

2009-01-01

Children with specific language impairment (SLI) often experience difficulties in the recall and repetition of verbal information. Archibald and Gathercole (2006) suggested that children with SLI are vulnerable across two separate components of a tripartite model of working memory (Baddeley and Hitch 1974). However, the hierarchical relationship between the 'slave' systems (temporary storage) and the central executive components places a particular challenge for interpreting working memory profiles within a tripartite model. This study aimed to examine whether a 'double-jeopardy' assumption is compatible with a hierarchical relationship between the phonological loop and central executive components of the working memory model in children with SLI. If a strong double-jeopardy assumption is valid for children with SLI, it was predicted that raw scores of working memory tests thought to tap phonological loop and central executive components of tripartite working memory would be lower than the scores of children matched for chronological age and those of children matched for language level, according to independent sources of constraint. In contrast, a hierarchical relationship would imply that a weakness in a slave component of working memory (the phonological loop) would also constrain performance on tests tapping a super-ordinate component (central executive). This locus of constraint would predict that scores of children with SLI on working memory tests that tap the central executive would be weaker relative to the scores of chronological age-matched controls only. Seven subtests of the Working Memory Test Battery for Children (Digit recall, Word recall, Non-word recall, Word matching, Listening recall, Backwards digit recall and Block recall; Pickering and Gathercole 2001) were administered to 14 children with SLI recruited via language resource bases and specialist schools, as well as two control groups matched on chronological age and vocabulary level, respectively. Mean group differences were ascertained by directly comparing raw scores on memory tests linked to different components of the tripartite model using a series of multivariate analyses. The majority of working memory scores of the SLI group were depressed relative to chronological age-matched controls, with the exception of spatial recall (block tapping) and word (order) matching tasks. Marked deficits in serial recall of words and digits were evident, with the SLI group scoring more poorly than the language-ability matched control group on these measures. Impairments of the SLI group on phonological loop tasks were robust, even when covariance with executive working memory scores was accounted for. There was no robust effect of group on complex working memory (central executive) tasks, despite a slight association between listening recall and phonological loop measures. A predominant feature of the working memory profile of SLI was a marked deficit on phonological loop tasks. Although scores on complex working memory tasks were also depressed, there was little evidence for a strong interpretation of double-jeopardy within working memory profiles for these children, rather these findings were consistent with an interpretation of a constraint on phonological loop for children with SLI that operated at all levels of a hierarchical tripartite model of working memory (Baddeley and Hitch 1974). These findings imply that low scores on complex working memory tasks alone do not unequivocally imply an independent deficit in central executive (domain-general) resources of working memory and should therefore be treated cautiously in a clinical context.

Comparison of effectiveness and safety of ultramini percutaneous nephrolithotomy (UMPNL) and retrograde intrarenal surgery (RIRS) in treatment of moderate-sized renal stones. The patients scheduled for surgery attributable to renal stones with the greatest diameter of 10 to 25 mm were prospectively analyzed. Patients were randomized into groups with tossing a coin method. The patients who had UMPNL and RIRS were defined as Group I and Group II, respectively. The groups were compared for demograhic data, stone characteristics, operative and postoperative data, stone-free status, and the complications. Student's t-test and Pearson's Chi square tests were used for statistical analysis. p < 0.05 was considered as statistically significant. There were 30 patients in Group I, and 43 patients in Group II. The groups were similar for age, gender, side of the stone, and surface area characteristics of the stone (p = 0.194, p = 0.470, p = 0.990, and p = 0.487, respectively). Stone-free rate was 80% (n = 24) in UMPNL, and 74.4% (n = 32) in RIRS (p = 0.579). Modified Clavien Classification Grade 1 to 2 and 3A to 3B complications were similar in two groups (p = 0.959 and p = 0.192, respectively). Comparison of stone-free rates was 93.3% in UMPNL, and 42.9% in RIRS groups for lower pole stones (p = 0.009). Groups I and II were significantly different for visual analog scale scores for postoperative pain (4.73 ± 1.25 vs 2.30 ± 1.12), hospital stay (2.46 ± 3.02 vs 1.37 ± 1.48 days), and time to return to normal daily life (11.26 ± 5.55 vs 6.65 ± 4.30 days) (p < 0.001, p < 0.001, and p < 0.001, respectively). Both UMPNL and RIRS procedures are effective and safe methods in treatment of middle-sized renal stones. However, UMPNL is more effective than RIRS in treatment of lower pole stones. RIRS is more advantageous when loss from work is taken into consideration.

Ionization state of L-phenylalanine at the air-water interface.

Griffith, Elizabeth C; Vaida, Veronica

2013-01-16

The ionization state of organic molecules at the air-water interface and the related problem of the surface pH of water have significant consequences on the catalytic role of the surface in chemical reactions and are currently areas of intense research and controversy. In this work, infrared reflection-absorption spectroscopy (IRRAS) is used to identify changes in the ionization state of L-phenylalanine in the surface region versus the bulk aqueous solution. L-phenylalanine has the unique advantage of possessing two different hydrophilic groups, a carboxylic acid and an amine base, which can deprotonate and protonate respectively depending on the ionic environment they experience at the water surface. In this work, the polar group vibrations in the surface region are identified spectroscopically in varying bulk pH solutions, and are subsequently compared with the ionization state of the polar groups of molecules residing in the bulk environment. The polar groups of L-phenylalanine at the surface transition to their deprotonated state at bulk pH values lower than the molecules residing in the bulk, indicating a decrease in their pK(a) at the surface, and implying an enhanced hydroxide ion concentration in the surface region relative to the bulk.

Social Justice and Social Order: Binding Moralities across the Political Spectrum

PubMed Central

2016-01-01

Two studies explored the relationship between political ideology and endorsement of a range of moral principles. Political liberals and conservatives did not differ on intrapersonal or interpersonal moralities, which require self-regulation. However differences emerged on collective moralities, which involve social regulation. Contrary to Moral Foundations Theory, both liberals and conservatives endorsed a group-focused binding morality, specifically Social Justice and Social Order respectively. Libertarians were the group without a binding morality. Although Social Justice and Social Order appear conflictual, analyses based on earlier cross-cultural work on societal tightness-looseness suggest that countries actually benefit in terms of economic success and societal well-being when these group-based moralities co-exist and serve as counterweights in social regulation.

The aim of this study was to determine the effect of light long-term ecstasy consumption on verbal short-term and working memory and to identify the cognitive processes contributing to task performance. Electroencephalogram was recorded while ecstasy users (N = 11), polydrug users (N = 13), and non-users (N = 13) completed forward and backward serial recognition tasks designed to engage verbal short-term memory and verbal working memory, respectively. All three groups displayed significantly lower digit-backward span than digit-forward span with ecstasy users displaying the greatest difference. The parietally distributed P3b was significantly smaller in the digits backward task than in the digits forward task in non-ecstasy-using controls. Ecstasy users did not show the reduced P3b component in the backward task that was seen in both non-ecstasy-using control groups. Ecstasy users' performance was suppressed more by the concurrent processing demands of the working memory task than that of the non-ecstasy-using controls. Non-ecstasy-using controls showed differential event-related potential wave forms in the short-term and working memory tasks, and this pattern was not seen in the ecstasy users. This is consistent with a reduction in the cognitive resources allocated to processing in working memory in ecstasy users. Copyright © 2011 John Wiley & Sons, Ltd.

In this article we ask whether the level of sickness benefit provision protects the health of employees, particularly those who are most exposed to hazardous working conditions or who have a little education. The study uses the European Working Condition Survey that includes information on 20,626 individuals from 28 countries. Health was measured by self-reported mental wellbeing and self-rated general health. Country-level sickness benefit provision was constructed using spending data from Eurostat. Group-specific associations were fitted using cross-level interaction terms between sickness benefit provision and physical and psychosocial working conditions respectively, as well as those with little education. The mental wellbeing of employees exposed to psychosocial job strain and physical hazards, or who had little education, was better in countries that offer more generous sickness benefit. These results were found in both men and women and were robust to the inclusion of GDP and country fixed effects. In the analyses of self-reported general health, few group-specific associations were found. This article concludes that generous sickness benefit provision may strengthen employee's resilience against mental health risks at work and risks associated with little education. Consequently, in countries with a generous provision of sickness benefit, social inequalities in mental health are smaller. © 2015 Foundation for the Sociology of Health & Illness.

The authors assess the long-term safety and efficacy of cervical disc replacement with the Prestige Cervical Disc in a prospective, randomized, multicenter trial at 7 years of follow-up. At 31 investigational sites, 541 patients with single-level cervical disc disease with radiculopathy were randomized to 1 of 2 treatment groups: 276 investigational group patients underwent anterior cervical discectomy and arthroplasty with the Prestige disc, and 265 control group patients underwent anterior cervical discectomy and fusion. Clinical outcomes included Neck Disability Index, the 36-Item Short-Form Health Survey, and neck and arm pain scores. Radiographs were assessed for angle of motion and fusion. Clinical and radiographic outcomes were evaluated preoperatively, intraoperatively, and at 1.5, 3, 6, 12, 24, 36, 60, and 84 months. Of the 541 patients treated, 395 patients (73%; 212 investigational and 183 control patients) completed 7 years of clinical follow-up. Significant improvements achieved by 1.5 months in both groups were sustained at 7 years. In the investigational group, mean Neck Disability Index improvements from preoperative scores were 38.2 and 37.5 at 60 and 84 months, respectively. In the control group, the corresponding means were 33.8 and 31.9. The differences between the investigational and control groups at the 60-month and 84-month periods were significant (p = 0.014 and 0.002, respectively). The overall rates of maintenance or improvement in neurological status in the investigational group were significantly higher: 92.2% and 88.2% at 60 months and 84 months, respectively, compared with 85.7% and 79.7% in the control group (p = 0.017 and 0.011, respectively). At 84 months, the percentage of working patients in the investigational group was 73.9%, and in the control group, 73.1%. Postoperatively, the implant effectively maintained average angular motion of 6.67° at 60 months and 6.75° at 84 months. Cumulative rates for surgery at the index level were lower (p < 0.001) in the investigational group (11 [4.8%] of 276) when compared with the control group (29 [13.7%] of 265) (based on life-table method), and there were statistical differences between the investigational and control groups with specific regard to the rate of subsequent revision and supplemental fixation surgical procedures. Rates for additional surgical procedures that involved adjacent levels were lower in the investigational group than in the control group (11 [4.6%] of 276 vs. 24 [11.9%] of 265, respectively). Cervical disc arthroplasty has the potential for preserving motion at the operated level while providing biomechanical stability and global neck mobility and may result in a reduction in adjacent-segment degeneration. The Prestige Cervical Disc maintains improved clinical outcomes and segmental motion after implantation at 7-year follow-up. Clinical trial registration no. NCT00642876 ( ClinicalTrials.gov ).

Work-related musculoskeletal disorders (MSD) are quite frequent in healthcare workers (HCWs), but data about MSD in home-based healthcare workers (HHWs) are lacking. In this study we describe the prevalence of MSD among Italian HHWs. A case-control study was carried out among 300 random-selected female HCWs, the sample comprising 100 HHWs, 100 HCWs with a low exposure to patient handling (MAPO - Movimentazione e Assistenza Pazienti Ospedalizzati - Movement and Assistance of Hospital Patients index 0-5) and 100 HCWs with high exposure to patient handling (MAPO index ≥ 5.01). As a negative control group, 200 visual display unit workers were also randomly selected. Musculoskeletal disorder cases were collected using a standardized case definition. A multivariate logistic regression analysis was performed comparing the MSD prevalence in the 4 groups. The overall prevalence of MSD was 17% in the reference group and 28.3% for HCWs. HHWs and HCWs with MAPO index ≥ 5.01 had similar prevalence of neck pain (9% and 11%, respectively), whereas lumbosacral pain prevalence was higher in the HHWs group (31%), with similar results in residential HCWs groups (21% in MAPO index 0-5 group and 25% in MAPO index ≥ 5.01 group). HCWs of group MAPO index ≥ 5.01 and HHWs showed the higher prevalence of upper limb complaints, with a prevalence of 20% and 10%, respectively. In multivariate regression analysis, prevalence of MSD complaints was quite similar in HHWs (adjusted odds ratio (OR_adj) = 2.335, 95% confidence interval (CI): 1.318-4.138) and in HCWs of the group MAPO ≥ 5.01 (OR_adj = 2.729, 95% CI: 1.552-4.797). The prevalence of MSD in the examined HCWs was relatively high, with HHWs appearing as a particularly high-risk group for lumbosacral back pain. In higher exposed HCWs, upper-limb symptoms were particularly frequent, probably reflecting the different tasks required to manage residential and homebased patients. In conclusion, this study reaffirms the high prevalence of MSD in HHWs, seemly similar to high-risk residential groups. Int J Occup Med Environ Health 2017;30(2):291-304.

School children (1608) were examined for three items (nails, scalp hairs and teeth) relating to personal hygiene and relevant infective conditions from two sets of villages i.e. one set where primary school teacher was working as primary health care worker (Group I) and the other set where Community Health Volunteer (CHV) was delivering primary health care (Group II). The objective was to evaluate the efficiency of school teachers' role vis-a-vis CHVs' in imparting health education to school children. Out of 1608 school children, 801 belonged to Group I villages and the remaining 807 to Group II villages. From the results, it was evident that children of Group I villages were better with respect to all the items related to personal hygiene and infective conditions excepting scalp infections, where difference was not statistically significant, indicating teachers' superiority over the CHVs' in imparting health education to school children.

Pilot study to examine the impact of long work hours and shift work on cognitive errors in nurses. Twelve-hour shifts are more commonly used in hospital settings and there is growing concern over the impact that extended and irregular work hours have on nurses' well-being and performance. Twenty-eight nurses working different shifts (8-hr days and 12-hr rotation) participated in this study. Nurses were assessed at the beginning of four consecutive shifts using actigraphy, a sleep diary and an after work questionnaire. Nurses working 12-hr rotations had less total sleep time and less sleep efficiency than 8-hr day nurses. Twelve-hour rotation nurses also napped more than their counterparts. There were no differences between the two groups with respect to cognitive errors. Twelve-hour rotations have a negative effect on nurses' sleep patterns. There is no evidence indicating 12-hr rotations increased errors. Nurse managers can implement specific strategies, such as greater shift work flexibility and designated quiet time, to reduce the effects of disturbed sleep patterns in nurses. © 2017 John Wiley & Sons Ltd.

Adoption of residents' working time restrictions potentially undermines surgical training by reduction of operating room exposure. Simulation has been proposed as a way to acquire necessary skills in a laboratory environment but remains difficult to incorporate into training schedules. This study assessed whether residents working successive nights could acquire endovascular skills similar to colleagues working day shifts. This prospective observational cohort study recruited 20 junior residents, divided into day shift and night shift groups by their respective call schedule. After initial cognitive skills training, a validated renal artery stent module on an endovascular simulator was completed over a series of seven sequential shifts during 1 week. The primary outcome measure was serial technical skill assessments. Secondary measures comprised assessments of activity, cognitive performance, introspective fatigue, quality, and quantity of preceding sleep. Both groups demonstrated significant learning curves for total time at the first session median vs seventh session median (181 vs 564 seconds [P < .001]; night, 1399 vs 572 [P < .001]), fluoroscopy time (day, 702 vs 308 seconds, [P < .001]; night, 669 vs 313 [P < .001]), and contrast volume (day, 29 vs 13 mL [P < .001]; night, 40 vs 16 [P < .001]). Residents working day shifts reached plateau 1 day earlier in the above measures vs those on night duty. The night shift group walked more steps (P < .001), reviewed more patients (P < .001), performed worse on all cognitive assessments (P < .05), slept less (P < .05), had poorer quality of sleep (P = .001), and was more fatigued (P < .001) than the day shift group. Acquired skill was retained a week after completion of shifts. Technical skills training after night shift work enables acquisition of endovascular technical skills, although it takes longer than after day shift training. This study provides evidence for program directors to organize simulation-based training schedules for residents on night shift rotations. Copyright © 2011. Published by Mosby, Inc.

Longitudinal studies of neurodevelopmental disorders that are diagnosed at or before birth and which are associated with specific learning difficulties at school-age provide one method for investigating developmental precursors of later-emerging academic disabilities. Spina bifida myelomeningocele (SBM) is a neurodevelopmental disorder associated with particular problems in mathematics, in contrast to well-developed word reading. Children with SBM (n = 30) and typically developing children (n = 35) were used to determine whether cognitive abilities measured at 36 and 60 months of age mediated the effect of group on mathematical and reading achievement outcomes at 8.5 and 9.5 years of age. A series of multiple mediator models showed that: visual-spatial working memory at 36 months and phonological awareness at 60 months partially mediated the effect of group on math calculations; phonological awareness partially mediated the effect of group on small addition and subtraction problems on a test of math fluency; and visual-spatial working memory mediated the effect of group on a test of math problem solving. Groups did not differ on word reading, and phonological awareness was the only mediator for reading fluency and reading comprehension. The findings are discussed with reference to theories of mathematical development and disability and with respect to both common and differing cognitive correlates of math and reading. PMID:24269579

Scopolamine has been used in neuropsychopharmacology as a standard drug that leads to symptoms mimicking cognitive deficits seen during the aging process in healthy humans and animals. Scopolamine is known to be a nonselective muscarinic receptor blocker, but its chronic effect on the expression of certain hippocampal receptors is not clear. The aim of the present study was to determine the effect of chronic scopolamine administration on hippocampal receptor expression and spatial working memory in two different learning tasks, the water maze and the eight-arm radial maze. Male rats (8-12 months) were trained in both tasks. Subsequently, different groups received physiological saline or 0.1, 0.8, or 2 mg/kg scopolamine hydrobromide, respectively, for 15 days. After drug administration, the rats were retested for both tasks, and hippocampal expressions of NR2A, NR2B, nAChRα7, and mAChRM1 receptors were assessed by western blotting analysis. In both tasks, the spatial working memory was decreased dose dependently in all groups compared with the control group. In terms of receptor expressions, 0.8 and 2 mg/kg scopolamine administration significantly decreased NR2A protein expression, which corroborates suggestions of an interaction between cholinergic and glutamatergic receptors in the hippocampus.

The rationale behind the current workshop, which was hosted by Biospherical Instruments Inc. (BSI), was to update the community and get community input with respect to the following: topics not addressed during the first workshop, specifically the processing of above-water apparent optical property (AOP data) within the Processing of Radiometric Observations of Seawater using Information Technologies (PROSIT) architecture; PROSIT data processing issues that have developed or tasks that have been completed, since the first workshop; and NASA instrumentation developments, both above- and in-water, that are relevant to both workshops and next generation mission planning. The workshop emphasized presentations on new AOP instrumentation, desired and required features for processing above-water measurements of the AOPs of seawater, working group discussions, and a community update for the in-water data processing already present in PROSIT. The six working groups were organized as follows: a) data ingest and data products; b) required and desired features for optically shallow and optically deep waters; c) contamination rejection (clouds), corrections, and data filtering; d) sun photometry and polarimetry; e) instrumentation networks; and f) hyperspectral versus fixed-wavelength sensors. The instrumentation networks working group was intended to provide more detailed information about desired and required features of autonomous sampling systems. Plenary discussions produced a number of recommendations for evolving and documenting PROSIT.

Objective The aim of this study is to investigate the proliferation, differentiation and apoptosis of periodontal ligament stem cells (PDLSC) derived from different aged donors, and to evaluate the effects of aging on the biological characteristics of PDLSC.Methods Periodontal ligament tissues were obtained from 24 surgically extracted human premolars during orthodontics therapy. The specimens were divided into three groups according to the donor's age. Group A: 18-20 years, group B: 30-35 years, group C: 45-50 years. PDLSC were isolated and cultured using a tissue-block-based enzymolytic method by limiting dilution assay. The colony forming efficiency of PDLSC for three experimental groups was determined. Senescence-Associated β-Galactosidase (SA-β-G) expression in the three groups was examined using β-galactosidase staining working solution. Cell cycle and apoptosis of the PDLSC were examined by the flow cytometry. Alkaline phosphatase (ALP) activity was evaluated by ALP staining. The expression of osteoplastic differentiation related genes Runt-related transcription factor-2 (Runx-2), Collagen Type 1 (col-1), and ALP of PDLSC were examined by quantitative real-time RT-PCR.Results The colony forming efficiency of PDLSC in Group A, B and C was 36.67%, 22.67% and 9.33%, respectively, which decreased with donors' age (P<0.05). SA-β-G expression of the senescent PDLSC in group A, B and C were 4.14%, 16.39%, 50.38%, respectively (P<0.05). Cells in G2/S phase was 38.73%, 29.88%, 18.25% (P<0.05), and the apoptosis rate was 1.57%, 4.56%, 5.84% (P<0.05), in group A, B and C respectively. The ALP staining in the three groups decreased with the increase of donors' ages, and the expression of Runx-2, col-1 and ALP decreased gradually from group A to group C (all P<0.05), which indicated the osteogenic differentiation capacity of PDLSC decreased while donor aging.Conclusion Human PDLSC could be successfully isolated from periodontal ligament tissues of different aged donors. However, the proliferation and osteogenic differentiation capacity of PDLSC decreased while donor aging.

This study aimed to evaluate the associations between types of night shift work and different indices of obesity using the baseline information from a prospective cohort study of night shift workers in China. A total of 3,871 workers from five companies were recruited from the baseline survey. A structured self-administered questionnaire was employed to collect the participants' demographic information, lifetime working history, and lifestyle habits. Participants were grouped into rotating, permanent and irregular night shift work groups. Anthropometric parameters were assessed by healthcare professionals. Multiple logistic regression models were used to evaluate the associations between night shift work and different indices of obesity. Night shift workers had increased risk of overweight and obesity, and odds ratios (ORs) were 1.17 (95% CI, 0.97-1.41) and 1.27 (95% CI, 0.74-2.18), respectively. Abdominal obesity had a significant but marginal association with night shift work (OR = 1.20, 95% CI, 1.01-1.43). A positive gradient between the number of years of night shift work and overweight or abdominal obesity was observed. Permanent night shift work showed the highest odds of being overweight (OR = 3.94, 95% CI, 1.40-11.03) and having increased abdominal obesity (OR = 3.34, 95% CI, 1.19-9.37). Irregular night shift work was also significantly associated with overweight (OR = 1.56, 95% CI, 1.13-2.14), but its association with abdominal obesity was borderline (OR = 1.26, 95% CI, 0.94-1.69). By contrast, the association between rotating night shift work and these parameters was not significant. Permanent and irregular night shift work were more likely to be associated with overweight or abdominal obesity than rotating night shift work. These associations need to be verified in prospective cohort studies.

Workers in slaughterhouses are exposed to a wide range of biological contaminants, such as bacteria and fungi, due to their working environment. This study aimed to assess the prevalence of respiratory disorders among workers in slaughterhouses. This study was conducted on 81 workers in slaughterhouses and 81 healthy office workers as a reference group. The American Thoracic Society standard respiratory symptoms questionnaire was used to determine the prevalence of respiratory disorders. Besides, lung function tests were conducted using a calibrated spirometer at the beginning (preshift) and at the end (postshift) of the 1 st working day. Single-stage Anderson sampler was used to measure the concentration of bioaerosols in different parts of slaughterhouses. The prevalence of respiratory disorders, such as cough, productive cough, breathlessness, phlegm, and wheezing, was 3.17, 4.02, 3.07, 4.66, and 3.94 times, respectively, higher among workers in slaughterhouses compared with the reference group. The prevalence of respiratory disorders was significantly higher among workers in slaughterhouses. Thus, the significant reduction in the percentage predicted lung function among workers in slaughterhouses might be associated with exposure to bioaerosols in their work environment.

The upcoming International Classification of Diseases, 11th Revision for primary care use suggests inclusion of a new diagnostic construct, bodily (di)stress syndrome (BDS), for individuals with medically unexplained symptoms. We aimed to explore the long-term outcome of BDS in health care costs, work disability, and self-rated health. Consecutive patients consulting their family physician for a new health problem were screened for physical and mental symptoms by questionnaires (n = 1785). A stratified subsample was examined with a standardized diagnostic interview (n = 701). Patients with single-organ BDS (n = 124) and multiorgan BDS (n = 35), and a reference group with a family physician-verified medical condition (n = 880) were included. All included patients completed a questionnaire at 3, 12, and 24 months of follow-up. Register data on health care costs and work disability were obtained after 2 and 10 years of follow-up, respectively. Patients with BDS displayed poorer self-rated health and higher illness worry at index consultation and throughout follow-up than the reference group (p ≤ .001). The annual health care costs were higher in the BDS groups (2270 USD and 4066 USD) than in the reference group (1392 USD) (achieved significance level (ASL) ≤ 0.001). Both BDS groups had higher risk of sick leave during the first 2 years of follow-up (RRsingle-organ BDS = 3.0; 95% confidence interval [CI] = 1.8-5.0; RRmultiorgan BDS = 3.4; 95% CI = 1.5-7.5) and substantially higher risk of newly awarded disability pension than the reference group (HRsingle-organ BDS = 4.9; 95% CI = 2.8-8.4; HRmultiorgan BDS = 8.7; 95% CI = 3.7-20.7). Patients with BDS have poor long-term outcome of health care costs, work disability, and subjective suffering. These findings stress the need for adequate recognition and management of BDS.

Background: High levels of perceived stressful working conditions have been found to have an adverse effect on physical and mental health. Objectives: To examine the associations between self-reported stressful working conditions and Psychosomatic Symptoms (PSS), and to investigate possible gender differences. Methods: The present cross-sectional study comprises 430 nurses employed in Hebron district, Palestine. Self-reported stressful working conditions were recorded, and a Psychosomatic Symptoms Check list was used to assess prevalence of PSS. Findings: Median score on the psychosomatic symptom checklist for the group was 11, (range 1–21). Women reported more symptoms than men, with medians 11.6 and 10.0, respectively (p = .0001). PSS were associated with more self-reported stressful working conditions for both men (p < .0001) and women (p < .0001). The association was strongest among men. Conclusions: PSS were associated with high self-reported stressful working conditions, and this association was strongest among the men. PMID:27160155

Headaches and long working hours are important issues for workers. This study investigated the association between hours worked and the prevalence of headaches, and how that association varies with physical activity. Cross-sectional study with two-stage cluster sampling. Using data from a nationally representative sample of households in Japan, people aged 20-65 years who worked ≥35 h/week were studied, and the cross-sectional association between the number of hours worked per week (35-45, 46-55 and >55 h/week) and the prevalence rates of headaches of different severity was evaluated. Of 721 workers, 307 reported experiencing at least one headache per month. Compared with working 35-45 h/week, the prevalence ratios of severe or disabling headaches among individuals working >55 h/week were 1.38 [95% confidence interval (CI) 1.06-1.78] and 1.63 (95% CI 1.09-2.43), respectively. After stratification by the level of physical activity, the prevalence ratios were greater in the low-physical-activity group: 1.56 (95% CI 1.11-2.19) for severe headaches and 2.20 (95% CI 1.31-3.68) for disabling headaches. The number of hours worked was not associated with headaches in the high-physical-activity group. Among workers in the general population, long working hours were associated with the prevalence of headaches, and the association may depend on a lack of physical activity.

Physical activity in hot environments can increase the risk of heat stress or heat stroke in dogs. Heat tolerance is influenced by acclimatization to the environment, physical fitness, and hydration state. Three common strategies to promote hydration in working dogs are free access to water (W), oral electrolyte solutions (OESs), and administration of subcutaneous fluids (SQs). None of these methods have been compared for safety or efficacy in a working environment. In a cross-over design, seven vehicle-screening canines were randomly assigned to each of the three hydration strategies during working shifts at the Sarita, TX checkpoint. Physical, behavioral, and biochemical parameters were collected before, during, and after a work shift (mean 5.7 ± 0.8 h). Dogs were given 10 mL/kg oral W, 10 mL/kg chicken flavored OES, or 15 mL/kg of SQs initially followed by controlled access to W or OES. The dogs drank 15.61 ± 4.47 mL/kg/h of W and OES when in the OES group, compared to 7.04 ± 3.42 and 5.56 ± 4.40 mL of W, for the W and SQ groups, respectively. The median environmental temperature was 84.8°F (29.3°C). The median humidity was 70%. Based on mixed effects linear modeling, dogs in the OES and SQ groups had significantly higher total CO 2 , and lower packed cell volume and total plasma protein at the end of the day. Creatinine increased a small but significant amount in the SQ group and decreased in the OES group. Searching behaviors were independent of hydration strategy but highly related to the dog specific factors of sex, breed, and activity level. Under conditions of controlled activity in moderate heat and humidity, dogs accustomed to the work and the environment were more likely to increase fluid consumption and hydration when provided a flavored OES. Potential benefits of OES and SQ were indirect and no adverse effects were documented for any of the hydration strategies tested.

New strings for old Veneziano amplitudes. II. Group-theoretic treatment

Kholodenko, A. L.

2006-09-01

In this part of our four parts work we use theory of polynomial invariants of finite pseudo-reflection groups in order to reconstruct both the Veneziano and Veneziano-like (tachyon-free) amplitudes and the generating function reproducing these amplitudes. We demonstrate that such generating function and amplitudes associated with it can be recovered with help of finite dimensional exactly solvableN=2 supersymmetric quantum mechanical model known earlier from works of Witten, Stone and others. Using the Lefschetz isomorphism theorem we replace traditional supersymmetric calculations by the group-theoretic thus solving the Veneziano model exactly using standard methods of representation theory. Mathematical correctness of our arguments relies on important theorems by Shepard and Todd, Serre and Solomon proven respectively in the early 50s and 60s and documented in the monograph by Bourbaki. Based on these theorems, we explain why the developed formalism leaves all known results of conformal field theories unchanged. We also explain why these theorems impose stringent requirements connecting analytical properties of scattering amplitudes with symmetries of space-time in which such amplitudes act.

Assembling GHERG: Could "academic crowd-sourcing" address gaps in global health estimates?

2015-06-01

In recent months, the World Health Organization (WHO), independent academic researchers, the Lancet and PLoS Medicine journals worked together to improve reporting of population health estimates. The new guidelines for accurate and transparent health estimates reporting (likely to be named GATHER), which are eagerly awaited, represent a helpful move that should benefit the field of global health metrics. Building on this progress and drawing from a tradition of Child Health Epidemiology Reference Group (CHERG)'s successful work model, we would like to propose a new initiative - "Global Health Epidemiology Reference Group" (GHERG). We see GHERG as an informal and entirely voluntary international collaboration of academic groups who are willing to contribute to improving disease burden estimates and respect the principles of the new guidelines - a form of "academic crowd-sourcing". The main focus of GHERG will be to identify the "gap areas" where not much information is available and/or where there is a lot of uncertainty present about the accuracy of the existing estimates. This approach should serve to complement the existing WHO and IHME estimates and to represent added value to both efforts.

: The study analyzed the social representations of primary health care professionals on evaluative processes of groups that work with food and nutrition, and described the educational strategies used in this care. This was a qualitative study from 2012 to 2014 in the city of São Paulo, Brazil, in which 48 interviews were analyzed. In the analysis of the interviews, for classification of the educational strategies in learning categories and contents, Bogdan & Biklen and Zabala were used, respectively. The evaluative processes used the collective subject discourse technique, based on Jodelet's social representations. Three learning contents were found in the educational strategies and four social representations of the evaluative processes which combined to reveal the presence of a conflict by a practice directed by the work process to quantitative and individual evaluative criteria and a health-promoting practice that used inclusive approaches and participant evaluation. In this practice, the study implicitly identified the presence of autonomy in health. The study revealed the need to acknowledge and systematize group planning as an educational tool that qualifies and empowers comprehensive care.

Understanding planning ability measured by the Tower of London: an evaluation of its internal structure by latent variable modeling.

The Tower of London (TOL) is a widely used instrument for assessing planning ability. Inhibition and (spatial) working memory are assumed to contribute to performance on the TOL, but findings about the relationship between these cognitive processes are often inconsistent. Moreover, the influence of specific properties of TOL problems on cognitive processes and difficulty level is often not taken into account. Furthermore, it may be expected that several planning strategies can be distinguished that cannot be extracted from the total score. In this study, a factor analysis and a latent class regression analysis were performed to address these issues. The results showed that 4 strategy groups that differed with respect to preplanning time could be distinguished. The effect of problem properties also differed for the 4 groups. Additional analyses showed that the groups differed on average planning performance but that there were no significant differences between inhibition and spatial working memory performance. Finally, it seemed that multiple factors influence performance on the TOL, the most important ones being the score measurements, the problem properties, and strategy use.

The Formation of Nucleobases from the UV Irradiation of Astrophysical Ice Analogs

Materese, C. K.; Nuevo, M.; Sandford, S. A.

Nucleobases are the fundamental information bearing components of both RNA and DNA. They are central to all known terrestrial life and they are generally conserved between species. Biological nucleobases can be divided into two groups based on the N-heterocyclic molecules pyrimidine (uracil, cytosine, and thymine) and purine (adenine and guanine) respectively. Do date, no experimental conditions have been determined that could produce both pyrimidines and purines together, abiotically, in a ter-restrial environment or an early terrestrial analog. Organic materials produced in extraterrestrial envi-ronments may have been delivered to the primitive earth by comets and meteorites and may have contrib-uted to the emergence of life. To date, some, but not all nucleobases have been detected in meteorites and their isotopic signatures may be consistent with an extraterrestrial origin. Earlier work in our lab demonstrated that it is possible to produce all of the pyrimidine group nucleobases from the UV-irradiation of pyrimidine in astrophysically relevant ice analogs. Here we report our most recent work, which studied the formation of the purine group nucleobases under similar conditions.

Recent studies advocated the use of active cycling coupled with functional electrical stimulation to induce neuroplasticity and enhance functional improvements in stroke adult patients. The aim of this work was to evaluate whether the benefits induced by such a treatment are superior to standard physiotherapy. A single-blinded randomized controlled trial has been performed on post-acute elderly stroke patients. Patients underwent FES-augmented cycling training combined with voluntary pedaling or standard physiotherapy. The intervention consisted of fifteen 30-minutes sessions carried out within 3 weeks. Patients were evaluated before and after training, through functional scales, gait analysis and a voluntary pedaling test. Results were compared with an age-matched healthy group. Sixteen patients completed the training. After treatment, a general improvement of all clinical scales was obtained for both groups. Only the mechanical efficiency highlighted a group effect in favor of the experimental group. Although a group effect was not found for any other cycling or gait parameters, the experimental group showed a higher percentage of change with respect to the control group (e.g. the gait velocity was improved of 35.4% and 25.4% respectively, and its variation over time was higher than minimal clinical difference for the experimental group only). This trend suggests that differences in terms of motor recovery between the two groups may be achieved increasing the training dose. In conclusion, this study, although preliminary, showed that FES-augmented active cycling training seems to be effective in improving cycling and walking ability in post-acute elderly stroke patients. A higher sample size is required to confirm results. PMID:27990234

Horses, mules and donkeys are indispensable farming and working animals in many developing countries, and their health status is important to the farmers. Strongyle parasites are ubiquitous in grazing horses world-wide and are known to constitute a threat to equine health. This study determined the prevalence of strongyle infection, the efficacy of ivermectin and fenbendazole treatment, and strongyle re-infection rates of working horses during the dry months in Nicaragua. One hundred and five horses used by farmers for transport of people and goods were randomly allocated into three treatment groups, i.e., the IVM group treated with ivermectin, the FBZ group treated with fenbendazole and the control group treated with placebo. Determined by pre-treatment faecal egg counts (FECs), horses showed a high prevalence (94%) of strongyle parasites with high intensities of infection (mean FEC of 1117 eggs per gram (EPG) with an SD of 860 EPG, n=102). Body condition scores of all horses ranged from 1.5 to 3.5 with a mean of 2.4 (scales 1-5). Fourteen days after treatment faecal egg count reductions (FECRs) were 100% and 94% in the IVM and the FBZ groups, respectively. The egg reappearance period (ERP) defined as the time until the mean FEC reached 20% of the pre-treatment level, was estimated as 42 days for the FBZ group and 60 days for the IVM group. Individual faecal cultures were set up and the larval differentiation revealed a 36% prevalence of Strongylus vulgaris before treatment (n=45). In the FBZ group, 25% of the horses were S. vulgaris-positive 70 days post treatment compared to 11% in the IVM group. Our results indicate that strongyle infection intensities in Nicaragua are high and that S. vulgaris is endemic in the area. Furthermore, efficacies and ERPs of IVM and FBZ were within the expected range with no signs of anthelmintic resistance. Copyright © 2011 Elsevier B.V. All rights reserved.

Aim: The aim of the present study was to electrochemically evaluate corrosion resistance of RaCe and Mtwo files after repeated sterilization and preparation procedures. Study Design: A total of 450 rotary files were used. In the working groups, 72 files from each file type were distributed into 4 groups. RaCe and Mtwo files were used to prepare one root canal of the mesial root of extracted human mandibular first molars. The procedure was repeated to prepare 2 to 8 canals. The following irrigation solutions were used: group 1, RaCe files with 2.5% NaOCl; group 2, RaCe files with normal saline; group 3, Mtwo files with 2.5% NaOCl; and group 4, Mtwo files with normal saline in the manner described. In autoclave groups, 72 files from each file type were evenly distributed into 2 groups. Files were used for a cycle of sterilization without the use of files for root canal preparation. Nine new unused files from each file type were used as controls. Then the instruments were sent for corrosion assessment. Mann-Whitney U and Wilcoxon tests were used for independent and dependent groups, respectively. Results: Statistical analysis indicated that there were significant differences in corrosion resistance of files associated with working and autoclave groups between RaCe and Mtwo file types (p<0.001). Conclusions: Corrosion resistance of #25, #30, and #35 Mtwo files is significantly higher than that in RaCe files with similar sizes. Key words:Corrosion, NiTi instruments, autoclave, RaCe, Mtwo.

Language has been shown to play a critical role in social cognitive reasoning in preschool and school-aged children, but little research has been conducted with adolescents. During adolescence, the ability to understand figurative language becomes increasingly important for social relationships and may affect social adjustment. This study investigated the contribution of structural and figurative language to social cognitive skills in adolescents who present for mental health services and those who do not. One hundred and thirty-eight adolescents referred to mental health centers (clinic group) and 186 nonreferred adolescents (nonclinic group) aged 12-17 were administered measures of structural and figurative language, working memory, and social cognitive problem solving. We found that adolescents in the clinic group demonstrated less mature social problem solving overall, but particularly with respect to anticipating and overcoming potential obstacles and conflict resolution compared with the nonclinic group. In addition, results demonstrated that age, working memory, and structural and figurative language predicted social cognitive maturity in the clinic group, but only structural language was a predictor in the nonclinic group. Social problem solving may be particularly difficult for adolescents referred for mental health services and places higher demands on their cognitive and language skills compared with adolescents who have never been referred for mental health services. © 2013 The Authors.

This study explored the prevalence and work interference (WI) of upper extremity musculoskeletal discomfort (UEMSD) and investigated the associations of individual and work-related risk factors and using a notebook stand or docking station with UEMSD among symptomatic occupational notebook personal computer (PC) users. The participant group included 45 Turkish occupational notebook PC users. The study used self-reports of participants. The Turkish version of the Cornell Musculoskeletal Discomfort Questionnaire (T-CMDQ) was used to collect symptom data. UEMSD prevailed mostly in the neck, the upper back, and the lower back with prevalence rates of 77.8%, 73.3%, and 60.0% respectively, and with WI rates of 28.9%, 24.4%, and 26.7% respectively. Aggregated results showed that 44% of participants reported WI due to UEMSD in at least one body region. Significant risk factors were: being female, being aged <31 years, having computer work experience <10 years, and physical discomfort during computer use. UEMSD prevalence and WI rates were considerable in the neck, the upper back, and the lower back. Significant associations between certain risk factors and UEMSD were identified, but no association was found between using notebook stand and docking station and UEMSD among participants.

Taking 'women's work' 'like a man': husbands' experiences of care work.

We adopted a feminist, structural approach to husbands' experiences of caring for wives with Alzheimer's disease. This framework posited that men and women draw upon gender repertoires-situational ideals of behavior based upon their respective structural locations-that create gendered experiences of stress and coping strategies. We used a qualitative, constructivist approach to analyze in-depth interviews with 22 spousal caregivers and observations within support groups. Our analysis focused on the nine husbands, the strategies these men reported using to deal with problems that arose in their care work, and the extent to which these are congruent with the masculinities of White men in the United States. We found that these husbands' approaches to caregiving and their strategies for dealing with the work and feelings involved were rooted in their sense of selves as men. We outline their overall approaches to caregiving, identify six strategies husbands used to deal with problems stemming from care work-exerting force, focusing on tasks, blocking emotions, minimizing disruption, distracting attention, and self-medicating-and tie these to their structural positions as working-, middle-, and professional-class men. Theories of gender differences in the performance or quality of care work should tie these to structural arrangements. Unless the gendered bases upon which different styles or experiences are removed (i.e., structural inequality), designers of interventions cannot and should not expect to use the experience of one group to inform appropriate strategies for the other.

The aims of this study were to determine implications of inter- and intraindividual variation in exposure to respirable (quartz) dust and of heterogeneity in dust characteristics for epidemiologic research in construction workers. Full-shift personal measurements (n = 67) from 34 construction workers were collected. The between-worker and day-to-day variances of quartz and respirable dust exposure were estimated using mixed models. Heterogeneity in dust characteristics was evaluated by electron microscopic analysis and electron spin resonance. A grouping strategy based on job title resulted in a 2- and 3.5-fold reduction in expected attenuation of a hypothetical exposure-response relation for respirable dust and quartz exposure, respectively, compared to an individual based approach. Material worked on explained most of the between-worker variance in respirable dust and quartz exposure. However, for risk assessment in epidemiology, grouping workers based on the materials they work on is not practical. Microscopic characterization of dust samples showed large quantities of aluminum silicates and large quantities of smaller particles, resulting in a D(50) between 1 and 2 microm. For risk analysis, job title can be used to create exposure groups, although error is introduced by the heterogeneity of dust produced by different construction workers activities and by the nonuniformity of exposure groups. A grouping scheme based on materials worked on would be superior, for both exposure and risk assessment, but is not practical when assessing past exposure. In dust from construction sites, factors are present that are capable of influencing the toxicological potency.

The primary aim of this study was to examine the impact of physical activity (PA) in the natural environment (eg, "green exercise") on resting autonomic function in the Walks4Work intervention. A secondary aim was to assess the feasibility of Walks4Work in terms of adherence, change in PA levels, and cardiovascular health parameters. In an 8-week randomized control trial, 94 office workers in an international company were allocated to one of three groups: control, nature (NW), or built (BW) lunchtime walking route. Both walking groups were required to undertake two lunchtime walks each week. The NW route centered around trees, maintained grass, and public footpaths. In contrast, the BW consisted of pavement routes through housing estates and industrial areas. Data were collected at baseline and following the intervention. To investigate the impact of the intervention, mixed-design analysis of variance (ANOVA) were performed. A total of 73 participants completed the intervention (drop-out rate of 22%). No difference was observed in resting autonomic function between the groups. Self-reported mental health improved for the NW group only. PA levels increased at the intervention mid-point for all groups combined but adherence to the intervention was low with rates of 42% and 43% within the BW and NW groups, respectively. Accompanying a guideline of two active lunchtimes per week with low facilitator input appears inadequate for increasing the number of active lunchtimes and modifying cardiovascular health parameters in an office population. However, this population fell within normal ranges for cardiovascular measures and future research should consider investigating at-risk populations, particularly hypertensive individuals.

Clodronate is a bisphosphonate used for the treatment of postmenopausal osteoporosis and all conditions characterized by excess bone resorption. We have previously reported that intramuscular (IM) therapy with clodronate at a dose of 100 mg/week displays significant effects on bone mineral density (BMD) although a plateau effect is observed after 1 year of treatment. Previous reports indicate that the densitometric effects of bisphosphonates directly correlate with the drug dosage and suggest that using IM clodronate at doses higher than 100 mg/week may result in improved efficacy. However, to the best of our knowledge, this has never been proved. The primary endpoint of the study was the effect on BMD of IM clodronate 100 mg once weekly or 100 mg twice weekly in patients with postmenopausal osteoporosis. The incidence of non-traumatic vertebral fractures and adverse events was also reported. The present study was a randomized, open-label, parallel-group trial conducted between January 2007 and December 2009 in the Osteoporosis and Osteoarticular Instrumental Diagnosis Centre (University of Siena, Siena, Italy). The study involved 60 women, aged 57-78 years, with a history of postmenopausal osteoporosis for more than 5 years. Patients were randomized to receive IM clodronate 100 mg once weekly (Group A, 30 patients) or 100 mg twice weekly (Group B, 30 patients), for 2 years. Significant increases compared with baseline in BMD were observed for both groups at 1 and 2 years, with significantly higher increases for Group B compared with Group A. Group B displayed a BMD increase (± SD) at the lumbar spine of +4.0 % (± 2.1) and +5.9 % (± 2.0) at 1 and 2 year(s), respectively, compared with +2.8 % (± 1.7) and +3.5 % (± 2.2), respectively, observed for Group A. Similarly, Group B showed better performance compared with Group A for BMD increase at the femoral neck, with an observed increase of +3.5 % (± 1.7) and +5.4 % (± 1.8) at 1 and 2 year(s), respectively, compared with a change of +2.3 % (± 1.9) and +2.5 % (± 1.9), respectively, registered in Group A. Consistently, the BMD increase measured at the total femur was significantly higher for Group B [+3.4 % (± 1.9) and +4.9 % (± 2.1) at years 1 and 2, respectively] compared with Group A [+1.6 % (± 0.9) and +2.4 % (± 1.9) at years 1 and 2, respectively]. When the change in BMD from year 1 to year 2 was compared, a significant increase of BMD was seen in Group B in all the analysed regions, contrary to that observed for Group A where a plateau effect resulted in no significant change from year 1 to year 2. Three non-traumatic vertebral fractures occurred during the study: two in Group A and one in Group B. The present study indicates the superior performance of IM clodronate 200 mg weekly (100 mg twice weekly) compared with 100 mg once weekly in BMD in women with postmenopausal osteoporosis. This work demonstrated that administration of twice the drug dosage in a week significantly improved the efficacy of the treatment without inducing serious adverse events. Therefore, IM clodronate 200 mg weekly may be considered a valid therapeutic choice for the treatment of postmenopausal osteoporosis.

From mothers to daughters: transgenerational food and diet communication in an underserved group.

Studies show that young girls are highly influenced by their mothers' attitudes toward food and body image. To investigate the nature of the information about food that mothers transfer to their daughters, the researchers used focus groups comprising African American women. Results suggest that when educators work with low-income African American women, they should be cognizant of overeating from the perspectives of early food scarcity, reverence for the mother's authoritative role in the family and respect for cultural differences in body size norms. In addition, nutrition educators should counsel young mothers to understand the impact of their eating habits on their daughters.

In an all-Raman amplified, recirculating loop containing 100-km spans, we have tested dense wavelength-division multiplexing at 10 Gbits/s per channel, using dispersion-managed solitons and a novel, periodic-group-delay-complemented dispersion-compensation scheme that greatly reduces the timing jitter from interchannel collisions. The achieved working distances are ~9000 and ~20,000 km for uncorrected bit error rates of <10-8 and <10-3, respectively, the latter corresponding to the use of ``enhanced'' forward error correction; significantly, these distances are very close to those achievable in single-channel transmission in the same system.

Effects of Electromagnetic Radiation from Smartphones on Learning Ability and Hippocampal Progenitor Cell Proliferation in Mice.

Nonionizing radiation is emitted from electronic devices, such as smartphones. In this study, we intended to elucidate the effect of electromagnetic radiation from smartphones on spatial working memory and progenitor cell proliferation in the hippocampus. Both male and female mice were randomly separated into two groups (radiated and control) and the radiated group was exposed to electromagnetic radiation for 9 weeks and 11 weeks for male and female mice, respectively. Spatial working memory was examined with a Y maze, and proliferation of hippocampal progenitor cells were examined by 5-bromo-2'-deoxyuridine administration and immunohistochemical detection. When spatial working memory on a Y maze was examined in the 9(th) week, there was no significant difference in the spontaneous alternation score on the Y maze between the two groups. In addition, there was no significant difference in hippocampal progenitor cell proliferation. However, immunoreactivity to glial fibrillary acidic protein was increased in exposed animals. Next, to test the effect of recovery following chronic radiation exposure, the remaining female mice were further exposed to electromagnetic radiation for 2 more weeks (total 11 weeks), and spontaneous alternation was tested 4 weeks later. In this experiment, although there was no significant difference in the spontaneous alternation scores, the number of arm entry was significantly increased. These data indicate that although chronic electromagnetic radiation does not affect spatial working memory and hippocampal progenitor cell proliferation it can mediate astrocyte activation in the hippocampus and delayed hyperactivity-like behavior.

Knowledge on the occupational and social factors that influence the relationship between illness, absence from work and occupational mobility is at present insufficient. To map out, by social class and occupational group, the impact of health problems on work and the distribution of accidents and morbidity associated with occupation. Using data from the National Survey of the Italian Labour Force (ISTAT, 1999), covering a sample of 200,384 subjects, prevalence odds ratios of morbidity, work injuries and change of occupation due to health problems were calculated by social class and occupation, adjusting for age and residence. The working class showed a higher risk, due to health problems, of a reduction in time worked (OR = 3.70 in men and OR = 4.10 in women), of choosing to work part-time (OR = 2.04 in men and OR = 2.27 in women), or of withdrawing from the workforce (for artisans, skilled manual workers, farmers and agricultural labourers OR = 1.63 in men and OR = 1.47 in women). This class was also at a greater disadvantage not only with respect to accident rates (OR = 1.85 in men and OR = 1.88 in women), but also with respect to the time needed for post-trauma rehabilitation and return to work (for absences of one week to one month: OR = 1.67 and 1.83 for men and women, respectively; for absences of more than one month: OR = 1.29 and OR = 1.69). Moreover, the working class, when compared to other social classes, had a higher rate of suffering from illness, physical impairment or other physical and psychological problems caused or aggravated by working activity (25% in men and 32% in women). The ISTAT National Survey provides an estimate of minor accidents with prognoses of less than three days, including those not reported to the National Institute for Insurance against Occupational Accidents and Diseases (INAIL). This allows a preliminary exploration of the relationship between health problems and occupational mobility; however, it seems necessary to collect more detailed information in order to more exhaustively explore the mechanisms which generate the inequalities observed.

In Sweden, as well as in most industrialised countries, an increasing older population is expected to create a growing demand for health care staff. Previous studies have pointed to lack of proficient medical and nursing staff specialised in geriatric care, which poses serious threats to the care of a vulnerable population. At the same time, there are studies describing elderly care as a low-status career choice, attracting neither nurses nor student nurses. Judging from previous research it was deemed important to explore how nurses in elderly care perceive their work, thus possibly provide vital knowledge that can guide nurse educators and unit managers as a means to promote a career in elderly care. The aim of the present study was to illuminate how nurses, working in nursing homes and home-based care, perceived their professional work. This was a qualitative study using focus groups. 30 registered nurses in seven focus groups were interviewed. The participants worked in nursing homes and home-based care for the elderly in rural areas and in a larger city in southern Sweden. The interviews were analysed in line with the tradition of naturalistic inquiry. Our findings illustrate how nurses working in elderly care perceived their professional work as holistic and respectful nursing. Three categories of professional work emerged during analysis: (1) establishing long-term relationships, (2) nursing beyond technical skills, and (3) balancing independence and a sense of loneliness. The findings are important as they represent positive alternatives to the somewhat prevailing view on elderly care as depressing and undemanding. Nurse educators might use the key aspects as good examples, thus influencing student nurses' attitudes towards elderly care in a positive way. Elderly care agencies might find them helpful when recruiting and retaining nurses to a much needed area. Copyright © 2013 Elsevier Ltd. All rights reserved.

To examine the effect overactive bladder (OAB) and other lower urinary tract symptoms (LUTS) on health-related quality of life (HRQoL) in a population sample, as OAB often occurs in conjunction with many other LUTS. A nested case-control analysis was performed on men and women with (cases) and without (controls) OAB, from the EPIC study. OAB was assessed using 2002 International Continence Society definitions. Based on their responses to questions about LUTS, cases were classified into five groups; continent OAB, OAB with incontinence, OAB + postmicturition, OAB + voiding, and OAB + postmicturition + voiding. Both cases and controls were asked questions about symptom bother (OAB-q), generic QoL (EQ-5D), work productivity (Work Productivity and Activity Impairment, WPAI), depressive symptoms (Center for Epidemiologic Studies Depression Scale), sexual satisfaction, and erectile dysfunction (men only) using the Massachusetts Male Aging Study. Cases answered additional condition-specific questions HRQoL (OAB-q short form), Patient Perception of Bladder Condition and work productivity related to a specific health problem (WPAI-SHP). General linear models were used to evaluate group differences. Of the EPIC participants, 1434 identified OAB cases were matched by age, gender and country, with 1434 participants designated as controls. Cases and controls were primarily Caucasian (96.2% and 96.7%, respectively), and most (65%) were female; the mean age was 53.8 and 53.7 years, respectively. Comorbid conditions differed significantly by case/control status, with cases reporting significantly greater rates of chronic constipation, asthma, diabetes, high blood pressure, bladder or prostate cancer, neurological conditions and depression. There were significant differences between the cases and controls in all reported LUTS. The OAB + postmicturition + voiding group reported significantly greater symptom bother, worse HRQoL, higher rates of depression and decreased enjoyment of sexual activity, than the other subgroups. OAB has a substantial, multidimensional impact on patients; OAB with additional LUTS has a greater impact. The diagnosis and treatment of OAB should be considered in conjunction with other LUTS, to maximize treatment options and optimize patient outcomes.

This work evaluates the radiological risk that patients treated with I for differentiated thyroid cancer could present to relatives and occupationally exposed workers. Recently, the International Atomic Energy Agency issued document K9010241, which recommends that patient discharge from the hospital must be based on the particular status of each patient. This work measures effective dose received by caregivers of patients treated with I at the Instituto Nacional de Cancerología, Mexico City. Thermoluminescent dosimeters were carried during a 15-d period by 40 family caregivers after patient release from hospital. Relatives were classified into two groups, ambulatory and hospitalized, according to the release mode of the patient, and three categories according to the individual patient home and transport facilities. Categories A, B, and C were defined going from most to least adequate concerning public exposure risk. Measurements were performed for 20 family caregivers in each group. The effective dose received by all caregivers participating in this study was found to be less than 5 mSv, the recommended limit per event for caregivers suggested by ICRP 103. In addition, 70 and 90% of ambulatory and hospitalized groups, respectively, received doses lower than 1 mSv. Caregivers belonging to category C, with home situations that are not appropriate for immediate release, received the highest average doses; i.e., 2.2 ± 1.3 and 3.1 ± 1.0 mSv for hospitalized and ambulatory patients, respectively. Results of this work have shown that the proper implementation of radiation protection instructions for relatives and patients can reduce significantly the risk that differentiated thyroid cancer patients treated with I can represent for surrounding individuals. The results also stress the relevance of the patient's particular lifestyle and transport conditions as the prevailing factors related to the dose received by the caregiver. Therefore, the patient's status should be the criterion used to decide his/her release modality. This work provides support to recommend the implementation of the "patient specific release criteria" in accordance with ICRP 94, IAEA Safety Report No. 63, and IAE document K9010241 A for patients treated with radiopharmaceuticals.

Introduction The clinician’s skill, impression techniques, and materials play a very important role in recording fine details in an impression for accuracy of fixed partial denture prosthesis. Impression of prepared teeth and of the opposing arch can be recorded simultaneously by dual-arch trays, while the full arch metal trays are used for impressions of prepared teeth in one arch. Aim To measure and compare the accuracy of working dies made from impressions with metal and plastic dual arch trays and metal full arch trays, for two viscosities of impression material and by changing the sequence of pour of working and non-working sides. Materials and Methods A balanced design with independent samples was used to study the three variables (tray type, impression material viscosity, and pouring sequence). An impression made by dual arch trays and single arch trays were divided in to three groups (Group A-plastic dual arch tray, Group B-metal dual arch tray, Group C-full arch metal stock tray). Out of these three groups, two groups (Group A and B) were subdivided in to four subgroups each and one group (Group C) was subdivided in to two subgroups. A sample size of 30 was used in each subgroup yielding a total 300 impressions in three groups or ten subgroups. Impressions were made of a machined circular stainless steel die. All three dimensions (Occlusogingival, Mesiodistal, and Buccolingual) of the working dies as well as stainless steel standard die were measured three times, and the mean was used for the three standard sample values to which all working dies means were compared. Statistical analysis used for this study was a 3-factor analysis of variance with hypothesis testing at α =0.05. Results With respect to the selection of impression material viscosity statistically significant differences were found in the dies for the buccolingual and mesiodistal dimensions. Metal dual arch trays were slightly more accurate in the mesiodistal dimension in comparison to the plastic trays in reference of tray selection and in view of pouring sequence no differences were observed in occlusogingival dimension but in buccolingual and mesiodistal dimensions nonworking side was more accurate. Conclusion The gypsum dies produced from the dual arch impressions were generally smaller in all three dimensions than the stainless steel standard die. Plastic dual-arch trays were more accurate with rigid impression material and there was not statistically significant difference for sequence of pouring. Metal dual-arch trays were more accurate with monophase impression material and working side was more accurate. Stock metal full arch trays were more accurate for monophase impression material.

To evaluate the feasibility and efficacy of a fully integrated hybrid closed-loop (HCL) system (Medtronic MiniMed Inc., Northridge, CA), in day and night closed-loop control in subjects with type 1 diabetes, both in an inpatient setting and during 6 days at diabetes camp. The Medtronic MiniMed HCL system consists of a fourth generation (4S) glucose sensor, a sensor transmitter, and an insulin pump using a modified proportional-integral-derivative (PID) insulin feedback algorithm with safety constraints. Eight subjects were studied over 48 h in an inpatient setting. This was followed by a study of 21 subjects for 6 days at diabetes camp, randomized to either the closed-loop control group using the HCL system or to the group using the Medtronic MiniMed 530G with threshold suspend (control group). The overall mean sensor glucose percent time in range 70-180 mg/dL was similar between the groups (73.1% vs. 69.9%, control vs. HCL, respectively) (P = 0.580). Meter glucose values between 70 and 180 mg/dL were also similar between the groups (73.6% vs. 63.2%, control vs. HCL, respectively) (P = 0.086). The mean absolute relative difference of the 4S sensor was 10.8 ± 10.2%, when compared with plasma glucose values in the inpatient setting, and 12.6 ± 11.0% compared with capillary Bayer CONTOUR NEXT LINK glucose meter values during 6 days at camp. In the first clinical study of this fully integrated system using an investigational PID algorithm, the system did not demonstrate improved glucose control compared with sensor-augmented pump therapy alone. The system demonstrated good connectivity and improved sensor performance. © 2015 by the American Diabetes Association.

2007-01-01

A workplace survey study (N = 2215, response rate 47%) revealed that about 16% of the sample may be categorized as either perpetrators (5.4%), provocative victims (2.1%), or as targets of bullying (8.3%). Targets of bullying, provocative victims, and bullies were compared with those 84% who do not report any involvement with respect to bullying at work, self-esteem, aggressive tendencies, prior experiences of bullying, or experiences of role stress. Perpetrators were found to have a higher level of aggression than did the comparison group and the targets. Provocative victims manifested a low level of self-esteem and social competency combined with a high level of aggressiveness. Targets of bullying revealed low levels of self-esteem and social competency. Targets, provocative victims, and perpetrators reported elevated levels of role stress in the form of unclear or conflicting demands and expectations around work tasks and daily work.

Reducing social inequalities in health: work-related strategies.

PubMed

Siegrist, Johannes

2002-01-01

Despite reduced health risks in terms of physical and chemical hazards current trends in occupational life continue to contribute to ill health and disease among economically active people. Stress at work plays a crucial role in this respect, as evidenced by recent scientific progress. This paper discusses two leading theoretical models of work-related stress, the demand-control model and the model of effort-reward imbalance, and it summarizes available evidence on adverse health effects. As work stress in terms of these models is more prevalent among lower socioeconomic status groups, these conditions contribute to the explanation of socially graded risks of morbidity and mortality in midlife. Implications of this new knowledge for the design and implementation of worksite health-promotion measures are elaborated. In conclusion, it is argued that workplace strategies deserve high priority on any agenda that aims at reducing social inequalities in health.

Although "respect" and "dignity" are intuitive concepts, little formal work has addressed their systematic application in the ICU setting. After convening a multidisciplinary group of relevant experts, we undertook a review of relevant literature and collaborative discussions focused on the practice of respect in the ICU. We report the output of this process, including a summary of current knowledge, a conceptual framework, and a research program for understanding and improving the practice of respect and dignity in the ICU. We separate our report into findings and proposals. Findings include the following: 1) dignity and respect are interrelated; 2) ICU patients and families are vulnerable to disrespect; 3) violations of respect and dignity appear to be common in the ICU and overlap substantially with dehumanization; 4) disrespect may be associated with both primary and secondary harms; and 5) systemic barriers complicate understanding and the reliable practice of respect in the ICU. Proposals include: 1) initiating and/or expanding a field of research on the practice of respect in the ICU; 2) treating "failures of respect" as analogous to patient safety events and using existing quality and safety mechanisms for improvement; and 3) identifying both benefits and potential unintended consequences of efforts to improve the practice of respect. Respect and dignity are important considerations in the ICU, even as substantial additional research remains to be done.

The aim of this study was to synthesize thiolated poly(vinyl alcohol) (PVA) and to evaluate its mucoadhesive properties. Thiourea and 3-mercaptopropionic acid were utilized in order to obtain thiolated PVAs, namely, TPVA1 and TPVA2, respectively. TPVA1 and TPVA2 displayed 130.44 ± 14.99 and 958.35 ± 155.27 μmol immobilized thiol groups per gram polymer, respectively, which were then evaluated regarding reactivity of thiol groups, swelling behavior and mucoadhesive properties. Both thiolated PVAs exhibited the highest reactivity at pH 8.0 whereas more than 95% of free thiol groups were preserved at pH 5.0. Thiolation of PVA decelerated water uptake and prolonged disintegration time of test discs compared to unmodified PVA. Contact time of TPVA1- and TPVA2-based test discs on porcine intestinal mucosa was 3.2- and 15.8-fold prolonged, respectively, in comparison to non-thiolated PVA as measured by rotating cylinder method. According to tensile studies on mucosa, the total work of adhesion (TWA) and the maximum detachment force (MDF) were increased when compared to PVA. Furthermore, thiolated PVAs preserved higher percentage of viable cells compared to unmodified PVA within 24h as evaluated by MTT assay. Accordingly, thiolated PVA represents a novel excipient that can likely improve the mucoadhesive properties of various pharmaceutical formulations. Copyright © 2016 Elsevier B.V.

Masons working with concrete masonry unit block have high rates of work-related musculoskeletal disorders to the low back and shoulders associated with repetitively lifting and buttering heavy block. A new material, autoclaved aerated concrete, may reduce the risk of shoulder and back injury but, ergonomic evaluation is needed. This study evaluated shoulder exposure parameters, low back stress, and worker perceptions in two groups of journey level masons, one using CMU and the other using AAC block. Results indicate that for the left arm AAC masons spent significantly more time than CMU masons in static (38.2% versus 31.1%, respectively), and less time in slow motions (48.2% versus 52.2%, respectively) and faster motions (13.6% versus 16.7%, respectively) (p<0.05). CMU masons had significantly greater shoulder and low back pain (p=0.009) and they held block significantly longer than AAC masons (p<0.001). Low back compressive forces were high for both materials. Masons handling AAC demonstrated less left upper extremity stress but both materials were estimated to be hazardous to the low back. Copyright (c) 2009 Elsevier Ltd. All rights reserved.

Prospective study of 164 young men from the start of employment in grain elevators showed that of those seen at the initial evaluation of respiratory state only 30% were available for a complete four year follow up. The drop out of subjects could represent a health related selection leading to the underestimation of respiratory effects of exposure to grain dust as assessed in the survivor group. This hypothesis was examined by comparisons of longitudinal changes in lung function in four groups defined by the duration of follow up involving the initial examination and periodic evaluations after one, two, and four years of work. Sixty four men were tested only on the initial examination (group I), 18 underwent two (group II), 31 underwent three (group III), and 51 (group IV) all four examinations. The groups had similar mean ages (range: 19.4-20.1 years), mean duration of previous exposure to grain dust (range: 8-13 weeks), smoking habits, lung function, and prevalences of respiratory symptoms evaluated on the initial occasion. The average decline in lung function over the first year was associated with duration of follow up. The annual decline in FVC (ml) was 58 in group II, 41 in group III and -55 (increase) in group IV; the decline in FEV1 (ml) was 224, 130, and 70 respectively. The differences for the annual declines of FEV1, FEF25-759 Vmax509 and Vmax25 were significant between groups II and IV, and the FEF25-759 Vmax509 and Vmax25 differed significantly between groups II and III. The results show that the restriction of analysis to the survivors may underestimate the relation between work and respiratory impairment. PMID:1515349

The medial rectus muscle (MRM) is the medial boundary to the intraconal space of the orbit, and retraction of the MRM is oftentimes necessary for endoscopic removal of intraconal tumors, e.g., orbital hemangioma. We evaluated each of the reported methods of MRM retraction for endoscopic orbital surgery and quantified the degree of intraconal exposure conferred by each method. Eight orbits from four cadaver heads were dissected. In each orbit, medial orbital decompression was performed and the MRM was retracted by using four previously described techniques: (1) external MRM retraction at the globe insertion point by using vessel loop (external group), (2) transseptal MRM retraction by using vessel loop (transseptal group), (3) transchoanal retraction of the MRM by using vessel loop (choanal group), and (4) transseptal four-handed technique by using double ball retraction by a second surgeon (transseptal double ball group). The length, height, and area of exposure of the medial intraconal space were quantified and compared. The average ± standard deviation (SD) anterior-posterior exposures for the external group, transseptal group, and transseptal double ball group were 17.51 ± 3.39 mm, 16.59 ± 4.16 mm, and 18.0 ± 15.25 mm, respectively. The choanal group provided significantly less exposure (12.39 ± 3.44 mm, p = 0.049) than the other groups. The average ± SD vertical exposures for the transseptal group, choanal group, and transseptal double ball group were 12.53 ± 4.38 mm, 13.05 ± 5.86 mm, and 13.57 ± 3.74 mm, respectively. The external group provided significantly less exposure (4.51 ± 1.56 mm, p = 0.0072) than the other groups. The transseptal and transseptal double ball groups provided the greatest total access by surface area (58.88 ± 26.96 mm(2) and 62.94 ± 34.74 mm(2), respectively) compared with the external and choanal groups (34.82 ± 23.37 mm(2) and 43.10 ± 23.68 mm(2), respectively). Although the transseptal trajectory of MRM retraction was optimal, the difference in total area of exposure between the static vessel loop retraction and the dynamic, four-handed technique with double ball instrument retraction was not significant. Of note, the exposure provided by the choanal technique required the surgeon to work both above and below the muscle. Retraction of the MRM toward the choanae provided the least length of exposure, and external retraction exposed the least height and total area. Transseptal MRM retraction was most favorable and provided the largest endoscopic corridor to the medial intraconal space. A four-handed approach for endoscopic intraconal surgery of the orbit may offer advantages in dynamic adjustments in retraction.

Background: Wellbeing is one’s evaluation and judgment of one’s life. It consists of 3 dimensions: positive affectivity, negative affectivity, and life satisfaction. Objectives: This study aimed to compare the subjective wellbeing and positive future expectations between working and nonworking adolescents. Patients and Methods: The study was designed as descriptive and comparative. The study sample consisted of 420 working and 482 nonworking adolescents (n = 902) aged 15 - 20 years, who were randomly recruited from two occupational education centers in Istanbul, Turkey and two high schools (formal educations) in the same district. Results: Adolescent subjective wellbeing scale (ASWS) total mean (SD) scores for working adolescents and nonworking adolescents were 48.76 (9.50) and 49.72 (8.01), respectively. In addition, positive future expectations scale (PFES) total mean (SD) scores for working adolescents and nonworking adolescents were 18.71 (4.50) and 19.06 (3.49), respectively. In this study, no significant difference was found between the general wellbeing (scale total median score) scores of the working and nonworking adolescent groups (Z = 1.01, P = 0.315). However, significant differences were found in the family relations satisfaction (Z = 3.23, P = 0.002) and relations with significant others (Z = 2.85, P = 0.004) subscales of the ASWS. Conclusions: A positive relationship was found between adolescent subjective wellbeing and positive future expectations. It was found that nonworking adolescents scored higher on the dimensions of “family relations” and “relations with significant others” of subjective wellbeing compared to those dimensions in working adolescents.

Job crafting, an employee-initiated job design/redesign, has become important for employees' well-being. However, most studies on the relationship between job crafting and employees' well-being have been conducted in western countries; thus, it is unclear whether job crafting can be effectively applied to Asian cultures, such as Japan, which emphasizes group harmony. The aim of this study was to examine the cross-sectional associations of self-reported job crafting with work engagement and psychological distress among employees in Japan. A questionnaire survey through the internet was conducted among all employees of a manufacturing company in Japan. We analyzed the data from 894 respondents, all employees with regular employment. Job crafting, work engagement, and psychological distress were assessed using the Japanese version of the Job Crafting Questionnaire, the Japanese version of the Utrecht Work Engagement Scale (UWES), and the Brief Job Stress Questionnaire (BJSQ), respectively. Hierarchical multiple regression showed that increasing structural job resources, social job resources, and challenging job demands was significantly and positively associated with work engagement ( β  = 0.31, p  < 0.001; β  = 0.14, p  < 0.001; β  = 0.36, p  < 0.001, respectively). For psychological distress, increasing structural job resources was significantly and negatively associated with psychological distress ( β  = -0.15, p  < 0.001). Our study suggests that increasing structural job resources is associated with higher work engagement and lower psychological distress. In addition, increasing social job resources and challenging job demands are also associated with higher work engagement.

Background In South Korea, the number of workers suffering from mental illnesses, such as depression, has rapidly increased. There is growing concern about depressive symptoms being associated with both working conditions and psychosocial environmental factors. Objectives To investigate potential psychosocial environmental moderators in the relationship between working conditions and occupational depressive symptoms among wage workers. Methods Data were obtained from the wage worker respondents (n = 4,095) of the Korean National Health and Nutrition Examination Survey of 2009. First, chi-square tests confirmed the differences in working conditions and psychosocial characteristics between depressive and non-depressive groups. Second, multivariate logistic regression analysis was performed to examine the moderating effects of the psychosocial environmental factors between working conditions and depressive symptoms. Results After adjusting for potential covariates, the likelihood of depressive symptomatology was high among respondents who had dangerous jobs and flexible work hours compared to those who had standard jobs and fixed daytime work hours (OR = 1.66 and 1.59, respectively). Regarding psychosocial factors, respondents with high job demands, low job control, and low social support were more likely to have depressive symptoms (OR = 1.26, 1.58 and 1.61, respectively). Conclusions There is a need to develop non-occupational intervention programs, which provide workers with training about workplace depression and improve social support, and the programs should provide time for employees to have active communication. Additionally, companies should provide employees with support to access mental healthcare thereby decreasing the occurrence of workplace depression. PMID:27373792

Purpose The proteasome inhibitor bortezomib undergoes oxidative hepatic metabolism. This study (NCI-6432; NCT00091117) was conducted to evaluate bortezomib pharmacokinetics and safety in patients with varying degrees of hepatic impairment, to inform dosing recommendations in these special populations. Methods Patients received bortezomib on days 1, 4, 8, and 11 of 21-day cycles. Patients were assigned to four hepatic function groups based on the National Cancer Institute Organ Dysfunction Working Group classification. Those with normal function received bortezomib at the 1.3 mg/m2 standard dose. Patients with severe, moderate, and mild impairment received escalating doses from 0.5, 0.7, and 1.0 mg/m2, respectively, up to a 1.3 mg/m2 maximum. Serial blood samples were collected for 24 hours post-dose on days 1 and 8, cycle 1, for bortezomib plasma concentration measurements. Results Sixty-one patients were treated, including 14 with normal hepatic function and 17, 12, and 18 with mild, moderate, and severe impairment, respectively. Mild hepatic impairment did not alter dose-normalized bortezomib exposure (AUC0-tlast) or Cmax compared with patients with normal function. Mean dose-normalized AUC0-tlast was increased by approximately 60% on day 8 in patients with moderate or severe impairment. Conclusions Patients with mild hepatic impairment do not require a starting dose adjustment of bortezomib. Patients with moderate or severe hepatic impairment should be started at a reduced dose of 0.7 mg/m2. PMID:22394984

For lung cancer surgery, a narrative operative report is the standard reporting procedure, whereas a synoptic-style report is increasingly utilized by healthcare professionals in various specialties with great success. A synoptic operative report more succinctly and accurately captures vital information and is rapidly generated with good intraobserver reliability. The objective of this study was to systematically develop a synoptic operative report for lung cancer surgery following a modified Delphi consensus model with the support of the Canadian thoracic surgery community. Using online survey software, thoracic surgeons and related physicians were asked to suggest and rate data elements for a synoptic report following the modified Delphi consensus model. The consensus exercise-derived template was forwarded to a small working group, who further refined the definition and priority designation of elements until the working group had reached a satisfactory consensus. In all, 139 physicians were invited to participate in the consensus exercise, with 36.7%, 44.6%, and 19.5% response rates, respectively, in the three rounds. Eighty-nine elements were agreed upon at the conclusion of the exercise, but 141 elements were forwarded to the working group. The working group agreed upon a final data set of 180 independently defined data elements, with 72 mandatory and 108 optional elements for implementation in the final report. This study demonstrates the process involved in developing a multidisciplinary, consensus-based synoptic lung cancer operative report. This novel report style is a quality improvement initiative to improve the capture, dissemination, readability, and potential utility of critical surgical information.

This work aims to characterize the relationship between tear film neuropeptide substance P and the structural integrity of the sub-basal nerve plexus in diabetes. Seventeen healthy control participants and nine participants with diabetes were recruited in this cross-sectional study. Total protein content and substance P concentrations were determined in the flush tears of participants. Corneal nerve morphology was assessed by capturing the corneal sub-basal nerve plexus using the Heidelberg Retinal Tomograph II with the Rostock Corneal Module (Heidelberg Engineering GmbH, Heidelberg, Germany) in the central cornea. Corneal nerve fiber density (CNFD) was measured using ACCMetrics (M.A. Dabbah, Imaging Science and Biomedical Engineering, Manchester, UK) on eight captured images. Comparisons between groups were made using independent samples t-tests. Correlations between parameters were analyzed using Pearson's correlations. Substance P concentrations were significantly higher in the tears of the control group compared to participants with diabetes (4150 ± 4752 and 1473 ± 1671 pg/mL, respectively, P = .047). There was no significant difference in total protein content between the groups (3.4 ± 1.8 and 2.6 ± 1.7 mg/mL in the control and diabetes groups, respectively, P = .262). CNFD was significantly lower in the participants with diabetes compared to the control group (16.1 ± 5.7 and 21.5 ± 7.0 mm/mm, respectively, P = .041). There was a moderate correlation between substance P and CNFD (r = 0.48, P = .01). Substance P is expressed at a significantly lower level in the tears of people with diabetes compared with healthy controls. The positive correlation between substance P and corneal nerve density indicates that substance P may be a potential biomarker for corneal nerve health.

Indwelling double J ureteral stents are used routinely in the resolution of ureteral obstruction caused by different etiologies. Evaluation of urinary symptoms related to double-J stent, indicate that these affect 73-90% of patients. We conducted a prospective, randomized study, to evaluate the efficacy of tamsulosin, oxybutinin and combination therapy in improving the urinary symptoms. Patients who underwent ureteral stent placement after ureterolithotripsy (total 51), were randomized into three groups: Group I: Tamsulosin 0.4 mg. Once per day(17 patients), Group II: Oxybutinin 5 mg. once per day (17 patients), Group III: Tamsulosin+ oxybutynin once per day (17 patients). All the groups received the drugs for three weeks and completed a Spanish validated Ureteral Stent Symptom Questionnaire (USSQ) at day 7 and 21. Repeated measures ANOVA showed mean urinary symptom index score was 22.3 vs. 15.5 in group three (p<0.001) at day 7 and 21 respectively. The mean work performance index was 6.6 vs 8.1 (p=0.049) favoring tamsulosin group, the mean sexual score was 0.5 vs 1.5 (p=0.03). Among additional problems the mean was 7.2 vs 6.2 (p=0.03). No significant difference was noted among pain and general health index. No side effects were reported. Combination therapy with tamsulosin and oxybutynin improved irritative symptoms and work performance as well as sexual matters. Combination therapy should be considered for patients who complained of stent related symptoms.

Previous studies have demonstrated that a low-intensity resistance exercise, combined with vascular occlusion, results in a marked increase in muscular size and strength. We investigated the optimal pressure for reduction of muscle blood flow with resistance exercise to increase the muscular strength and endurance. Twenty-one subjects were randomly divided into four groups by the different application of vascular occlusion pressure at the proximal of thigh: without any pressure (0-pressure group), with a pressure of 50mmHg (50-pressure group), with a pressure of 150mmHg (150-pressure group), and with a pressure of 250mmHg (250-pressure group). The isokinetic muscle strength at angular velocities of 60 and 180 degrees /s, total muscle work, and the cross-sectional knee extensor muscle area were assessed before and after exercise. Exercise was performed three times a week over an 8-week period at an intensity of approximately 20% of one-repetition maximum for straight leg raising and hip joint adduction and maximum force for abduction training. A significant increase in strength at 180 degrees /s was noted after exercise in all subjects who exercised under vascular occlusion. Total muscle work increased significantly in the 50- and 150-pressure groups (P<0.05, P<0.01, respectively). There was no significant increase in cross-sectional knee extensor muscle area in any groups. In conclusion, resistance exercise with relatively low vascular occlusion pressure is potentially useful to increase muscle strength and endurance without discomfort.

This paper presents a synthesis of the ENEA-Bologna Nuclear Data Group programme dedicated to generate and validate group-wise cross section libraries for shielding and radiation damage deterministic calculations in nuclear fission reactors, following the data processing methodology recommended in the ANSI/ANS-6.1.2-1999 (R2009) American Standard. The VITJEFF311.BOLIB and VITENDF70.BOLIB finegroup coupled n-γ (199 n + 42 γ - VITAMIN-B6 structure) multi-purpose cross section libraries, based on the Bondarenko method for neutron resonance self-shielding and respectively on JEFF-3.1.1 and ENDF/B-VII.0 evaluated nuclear data, were produced in AMPX format using the NJOY-99.259 and the ENEA-Bologna 2007 Revision of the SCAMPI nuclear data processing systems. Two derived broad-group coupled n-γ (47 n + 20 γ - BUGLE-96 structure) working cross section libraries in FIDO-ANISN format for LWR shielding and pressure vessel dosimetry calculations, named BUGJEFF311.BOLIB and BUGENDF70.BOLIB, were generated by the revised version of SCAMPI, through problem-dependent cross section collapsing and self-shielding from the cited fine-group libraries. The validation results on the criticality safety benchmark experiments for the fine-group libraries and the preliminary validation results for the broad-group working libraries on the PCA-Replica and VENUS-3 engineering neutron shielding benchmark experiments are reported in synthesis.

Hypertension is one of the most relevant risk factors for cardiovascular disease; however, little is known about differences in hypertension by occupation. The aim of this study was to explore the association between occupational group and prevalent hypertension. Cross-sectional data of the CARLA study were used, a representative sample of an East German population aged 45-83. Job titles of the current or last held occupation of 967 men and 808 women were coded using the German classification of occupation. Hypertension was defined as blood pressure of ≥140 mmHg (systolic), ≥90 mmHg (diastolic) or use of antihypertensives. Sex-stratified, age-adjusted prevalence risk ratios (PR) with 95% confidence intervals (CI) were calculated for 31 occupational groups. Hypertension was prevalent in 79% of the population. In men, highest age-adjusted prevalence ratios were observed in metal-processing workers, carpenters/painters, and electricians with PRs of 1.31 (CI 1.04-1.65), 1.28 (CI 1.00-1.64), and 1.21 (0.95-1.53), respectively, compared to office clerks. In women, highest PRs were found in technicians/forewomen, scrutinisers/storekeepers, and food-processing occupations with PR 1.28 (1.09-1.49), 1.23 (0.99-1.51), and 1.22 (1.01-1.48), respectively. Adjustment for education, smoking, body mass index, and current work hours did not fully explain occupational differences. Excluding currently non-working subjects lead to decreased PRs in men and to increased PR in women. Differences in the prevalences of hypertension by occupational group were only partly explained by conventional risk factors and may require workplace interventions targeted at high-risk occupations. Longitudinal data with large cohorts and work-related exposure assessment are needed to confirm a temporal relationship between occupation and incident hypertension.

N-methyl-D-aspartate receptors (NMDAR) are involved in neuronal plasticity. To assess their role simultaneously in spatial working memory and non-cognitive learning, we used NMDAR antagonists and the Allothetic Place Avoidance Alternation Task (APAAT). In this test rats should avoid entering a place where shocks were presented on a rotating arena which requires cognitive coordination for the segregation of stimuli. The experiment took place 30 min after intraperitoneal injection of memantine (5, 10, 20 mg/kg b.w.: MemL, MemM, MemH, respectively) and (+)MK-801 (0.1, 0.2, 0.3 mg/kg b.w.: MK-801L, MK-801M, MK-801H, respectively). Rats from the control group were intact or injected with saline (0.2 ml/kg). Over three consecutive days the rats underwent habituation, two avoidance training intervals with shocks, and a retrieval test. The shock sector was alternated daily. The after-effects of the agents were tested on Day 21. Rats treated with low dose memantine presented a longer maximum time avoided and fewer entrances than the MemH, MK-801M, MK-801H and Control rats. The shocks per entrances ratio, used as an index of cognitive skill learning, showed skill improvement after D1, except for rats treated by high doses of the agents. The activity levels, indicated by the distance walked, were higher for the groups treated with high doses of the agents. On D21 the MK801H rats performed the memory task better than the MemH rats, whereas the rats' activity depended on condition, not on the group factor. These results suggest that in naïve rats mild NMDAR blockade by low-dose memantine improves working memory related to a highly challenging task. PMID:24385956

The study aimed at evaluating effectiveness of the web-based intervention, "The Helpers' Stress," in reducing job burnout and enhancing work engagement among professionals working with trauma survivors. Participants were randomly allocated to 1 of the 3 intervention modules: 1 - the self-efficacy enhancement (N = 87), 2 - the social support enhancement (N = 85), or to 3 - the educational module (comparison group, N = 81). Participants completed the online questionnaires before the intervention (T1), immediately after (T2), and 4 weeks after the intervention (T3). Due to high drop-out rate at T2 and T3 in social support enhancement module, we excluded from analysis participants assigned to this condition. Participants assigned to the self-efficacy enhancement module presented higher levels of self-efficacy (at T2 and T3), compared to those assigned to the educational module. Job burnout decreased significantly between T1 and T2, and between T2 and T3, and work engagement increased significantly between T1 and T2, and between T1 and T3, among participants assigned to both modules mentioned above. Self-efficacy (T2) mediated the relationship between the group assignment (educational module vs. self-efficacy enhancement module) and respectively job burnout (T3) or work engagement (T3). The results of our study highlight the role of self-efficacy in reducing job burnout and increasing work engagement. Med Pr 2016;67(2):223-237.

We explored the oxidation reactions of lignin model compounds directly induced by ionic liquids under metal-free conditions. In this work, it was found that ionic liquid 1-octyl-3-methylimidazolium acetate as a solvent could promote the aerobic oxidation of lignin model compound 2-phenoxyacetophenone (1) and the yields of phenol and benzoic acid from 1 could be as high as 96% and 86%, respectively. A possible reaction pathway was proposed based on a series of control experiments. An acetate anion from the ionic liquid attacked the hydrogen from the β-carbon thereby inducing the cleavage of the C-O bond of the aromatic ether. Furthermore, it was found that 2-(2-methoxyphenoxy)-1-phenylethanone (4) with a methoxyl group could also be transformed into aromatic products in this simple reaction system and the yields of phenol and benzoic acid from 4 could be as high as 98% and 85%, respectively. This work provides a simple way for efficient transformation of lignin model compounds.

Our aim was to study the antibiotic prescription practices and the knowledge about antibiotic costs, brand and generic drugs of paediatricians working in two hospitals in Greece. The 2007 national guidelines were used as the gold standard for antibiotic prescription. A total of 126 paediatricians participated in the study (50.4% response rate). The mean compliance rate with the guidelines was 50.1% (range per infection: 10.6-84.7%). The mean scores of knowledge about antibiotic costs and about brand name and generic drugs were 35.6 and 60.3%, respectively. Linear regression analysis found a significant association between the mean compliance rate with the national guidelines and the paediatricians' age (mean compliance rates were 49.1, 53.0, and 43.0% in the ≤ 30, 31-40, and > 40 years age-groups, respectively; P  =  0.003). In conclusion, five years after the first national guidelines were issued in Greece only half of the paediatricians working in hospitals comply fully with them.

The Multispecialty Occupational Health Group (MSOHG), formed in 2005, is an informal coalition of societies representing professionals who work in, or are concerned with, interventional fluoroscopy. The group's long-term goals are to improve occupational health and operator and staff safety in the interventional laboratory while maintaining quality patient care and optimal use of the laboratory. MSOHG has conducted a dialogue with equipment manufacturers and has developed a list of specific objectives for research and development. The group has also represented the member societies in educating regulators, in educating interventionalists, and in fostering and collaborating on research into occupational health issues affecting interventionalists. Not least of the group's accomplishments, as a result of their collaboration in MSOHG, the group's members have developed a mutual respect that can serve as a basis for joint efforts in the future among interventionalists of different medical specialties.

To evaluate the previously developed physiological strain index (PSI) model using heart rate and skin temperature to provide further insight into the detection and estimation of thermal and physiological heat strain indices. A secondary aim was to characterize individuals who excel in their performance in the heat. 56 male participants completed 2 walking trials (3.5 miles per hour, 5% grade) in controlled environments of 43.3 °C and 15.5 °C (40% humidity). Core and skin temperature, along with heart rate and PSI, were continually monitored during exercise. Participants completed a physical fitness test. The logistic regression model exhibited 4 false positives and 1 false negative at the 40% decision boundary. The "Not at Risk" group (N = 33) had higher body weight (84 ± 13 vs. 77 ± 10 kg, respectively) compared to the "At Risk" (N = 23) group, p < 0.05. The "Not at Risk" group had a faster 3-mile run time compared to the "At Risk" group (21:53 ± 3:13 vs. 25:16 ± 2:37, respectively), p < 0.05. During the Heat Trial, the "At Risk" group had a higher rating of perceived exertion at 60 and 90 minutes compared to the "Not at Risk" group (13.5 ± 2.8 vs. 11.5 ± 1.8 and 14.8 ± 3.2 vs. 12.2 ± 2.0 for "At Risk" vs. "Not at Risk" at 60 and 90 minutes, respectively), p < 0.05. The previously developed model relating heart rate and skin temperature to PSI is highly accurate at assessing heat risk status. Participants classified as "At Risk" had lower physical performance scores and different body weights compared to the "Not at Risk" group and perceived themselves as working harder during exercise in the heat.

This study was aimed to determine whether the presence of sexually stimulated rams by photoperiodic and melatonin treatments can advance the resumption of post-partum sexual activity in Mediterranean ewes lambing in January and weaned at the end of the breeding season at 41°N, in March. Rams were exposed to two months of long days (16 h light/day) and given three melatonin implants at the end of the long days (sexually-activated rams; SAR). Control rams (CR) were exposed to the natural photoperiod. Thirty-six ewes weaned on 25 February were assigned to one of two groups. From 1 March to 30 June, one group was housed with four SAR males (SAR-treated; n = 18), and the other group (CR-treated; n = 18) was housed with four unstimulated rams. Ovulation was assessed once per week based on plasma progesterone concentrations. Estrus was monitored daily by marks left on ewes by rams' harnesses. SAR-treated ewes had a shorter ( p < 0.01) weaning-first estrus interval than CR-treated ewes (61 ± 17 days vs. 102 ± 47 days; mean date of first estrus after weaning on April 26 and June 6, respectively). The proportion of the ewes ovulating in April or May was higher ( p < 0.05) in the SAR-treated group than in the CR-treated group. SAR-treated ewes resumed estrous activity sooner than CR-treated ewes such that, in April, May, and June, the proportion of females that exhibited estrus was higher ( p < 0.01) in the SAR-treated group (72%, 89%, and 100%, respectively) than in the CR-treated group (17%, 44%, and 61%, respectively). In conclusion, the introduction at weaning of sexually activated rams advanced the resumption of estrous activity in ewes in spring. The practical implications of this work could be important in ewes adapted for intensive production and accelerated lambing systems.

Abstract While workplace physical exercise can help manage musculoskeletal disorders, less is known about psychosocial effects of such interventions. This aim of this study was to investigate the effect of workplace physical exercise on psychosocial factors among workers with chronic musculoskeletal pain. The trial design was a 2-armed parallel-group randomized controlled trial with allocation concealment. A total of 66 slaughterhouse workers (51 men and 15 women, mean age 45 years [standard deviation (SD) 10]) with upper limb chronic musculoskeletal pain were randomly allocated to group-based strength training (physical exercise group) or individual ergonomic training and education (reference group) for 10 weeks. Social climate was assessed with the General Nordic Questionnaire for Psychological and Social Factors at Work, and vitality and mental health were assessed with the 36-item Short Form Health Survey. All scales were converted to 0 to 100 (higher scores are better). Between-group differences from baseline to follow-up were determined using linear mixed models adjusted for workplace, age, gender, and baseline values of the outcome. Mean baseline scores of social climate, mental health, and vitality were 52.2 (SD 14.9), 79.5 (SD 13.7), and 53.9 (SD 19.7), respectively. Complete baseline and follow-up data were obtained from 30 and 31 from the physical exercise and reference groups, respectively. The between-group differences from baseline to follow-up between physical exercise and reference were 7.6 (95% CI 0.3 to 14.9), −2.3 (95% CI -10.3 to 5.8), and 10.1 (95% CI 0.6 to 19.5) for social climate, mental health, and vitality, respectively. For social climate and vitality, this corresponded to moderate effect sizes (Cohen d = 0.51 for both) in favor of physical exercise. There were no reported adverse events. In conclusion, workplace physical exercise performed together with colleagues improves social climate and vitality among workers with chronic musculoskeletal pain. Mental health remained unchanged.

The aim of this work was to study the effect of recombinant human (rh) FSH and LH on in vitro maturation of pig oocytes compared with a conventional hormonal supplement based on equine (PMSG) and human chorionic gonadotropins (hCG), as evaluated by the developmental ability of 3 types of pig embryos obtained by in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), or artificial activation (ATA). In Exp. 1, one cumulus-oocyte complex group (A group) was supplemented with rh-FSH and rh-LH (0.1 IU/mL each), and the other group (B group) was supplemented with PMSG and hCG (10 IU/mL each). No differences in nuclear maturation between the A and B groups were observed (68.5 vs. 71.4%, respectively). No differences were detected between hormonal treatments in the rates of cleavage or blastocyst formation of ATA, IVF, and ICSI embryos. Total cell number of the embryos was not significantly different in any experimental group (A: 31.1, 28.5, and 19.8 vs. B: 25.2, 25.5, and 20.6 for ATA, IVF, and ICSI embryos, respectively). In Exp. 2, the effects of different concentrations of rh-FSH and rh-LH (0.5, 0.1, or 0.05 IU/mL) in maturation medium on nuclear maturation and in vitro development of embryos obtained by IVF were studied. No effect of different hormonal concentrations on blastocyst formation rates was observed (8.5, 13.0, and 5.7%, respectively). Blastocyst cell number was not different in any experimental group. In conclusion, the results obtained here permit us to substitute PMSG and hCG with rh-FSH and rh-LH and to produce pig embryos obtained by IVF, ICSI, or ATA.

Both sleep disorders and sarcopenia are common among older adults. However, little is known about the relationship between these 2 conditions.This study aimed to investigate the possible association between sleep duration and sarcopenia in a population of Chinese community-dwelling older adults.Community-dwelling older adults aged 60 years or older were recruited. Self-reported sleep duration, anthropometric data, gait speed, and handgrip strength were collected by face-to-face interviews. Sarcopenia was defined according to the recommended algorithm of the Asian Working Group for Sarcopenia (AWGS).We included 607 participants aged 70.6 ± 6.6 years (range, 60-90 years) in the analyses. The prevalence of sarcopenia in the whole study population was 18.5%. In women, the prevalence of sarcopenia was significantly higher in the short sleep duration group (< 6 hours) and long sleep duration group (>8 hours) compared with women in the normal sleep duration group (6-8 hours; 27.5%, 22.2% and 13.9%, respectively; P = .014). Similar results were found in men; however, the differences between groups were not statistically significant (18.5%, 20.6%, and 13.0%, respectively; P = .356). After adjustments for the potential confounding factors, older women having short sleep duration (OR: 4.34; 95% CI: 1.74-10.85) or having long sleep duration (OR: 2.50; 95% CI: 1.05-6.99) had greater risk of sarcopenia compared with women having normal sleep duration. With comparison to men with normal sleep duration, the adjusted OR for sarcopenia was 2.12 (0.96-8.39) in the short sleep duration group and 2.25 (0.88-6.87) in the long sleep duration group, respectively.A U-shape relationship between self-reported sleep duration and sarcopenia was identified in a population of Chinese community-dwelling older adults, especially in women.

Inclusive research with people with intellectual disabilities is growing internationally but with few studies examining its feasibility. In undertaking a national study exploring what life was like in Ireland for people with intellectual disabilities, a community of practice was developed involving a core group of co-researchers: five people with intellectual disabilities, four university researchers and three service support staff. An additional cadre of 15 co-researchers with intellectual disabilities was recruited to undertake data gathering and analysis with 23 focus groups involving 168 participants. The research experience was documented through oral feedback, progress reports, minutes and a project review. The key learning is documented arising from the setting up of an inclusive advisory group and implementation of each of six research steps. The study demonstrates feasibility and the added value of university co-researchers recruiting and developing skills together with co-researchers with intellectual disabilities. Topics for further research and development are identified. This paper tells you about how people with intellectual disabilities worked with a group of university researchers. Both groups were called co-researchers and together they ran 23 focus groups across Ireland. People with intellectual disabilities talked about their lives and what could make them better. They said they needed to have a good place to live; a job; enough money; relationships; and acceptance as respected citizens. The university co-researchers wrote about what it was like doing research together and how people with intellectual disabilities joined the advisory group; decided on the questions; ran focus groups; and presented findings. Together they grew into a community of researchers where the university co-researchers shared their research skills and people with intellectual disabilities shared what it was like living with a disability. They both saw great value in working together and plan to work more to make this type of research happen. © 2013 John Wiley & Sons Ltd.

Fruits and vegetables contain many compounds presenting potential antioxidant activity. The objective of this study was to evaluate the effect of a green juice recipe in adult metabolism in order to identify new preventive dietary sources. This was a single-blind randomized controlled clinical trial. Recruitment and data were, respectively, made and collected at the Universidade Federal de Ciências da Saúde de Porto Alegre. Individuals who met all the inclusion criteria during the period of recruitment were included. Green juice (experimental group) or placebo (control group) were consumed from Monday to Friday between 8 and 9 am, in the amount of 300 mL for 60 days (except Saturdays and Sundays). To verify the effect of green juice on metabolism, the following were evaluated: (a) glycemia, plasma lipid profile, renal and liver functions, redox profile, and antioxidant enzymes; (b) anthropometry; and (c) well-being and anxiety. This study included 14 participants in the test group (juice group) and 13 controls (placebo group), with mean ages of 31.07 and 30.15 years, respectively. We did not observe a significant difference between the treatments. Dietary properties of vegetable and fruit juices are an area of significant interest. Together with an analysis of previous works, we suggest that green juice did not cause an improvement in metabolic function and there is a need for further research on this issue, mainly through different interventions and other samples.

The aim of this study was to investigate the relationship between nursing staff emotions and their surrounding environment, using the ancient system of feng shui. Two orientations of critical care bed spaces (wind and water groups, respectively) were mapped using a western bagua. Energy or 'chi' scores for nine emotions were calculated based on the positive or negative flow of chi in each of the two groups. During a two-week period, nursing staff were allocated to work in a bed space in either the wind or water groups; nursing staff who were not allocated to a study bed space acted as a control group. Participating nursing staff completed a questionnaire, ranking nine emotional states and their overall inner harmony, using a 11-point chi scale. In total, 108 questionnaires were completed. Critical bed space orientation according to feng shui principles was not related to nurse-reported chi scores or inner harmony (p > 0.05 for all measurements). There was also poor correlation between the bagua-predicted and reported chi scores for both the wind and water groups (R 2  = 0.338 and 0.093, respectively). The use of feng shui to guide the layout of critical care bed spaces does not improve the emotional well-being of nursing staff. © 2017 The Association of Anaesthetists of Great Britain and Ireland.

It is not known whether working in surface lignite mines can cause x-ray lesions or disorders of respiratory function. The aim of the study was to investigate the diachronic impact of environmental pollution on the respiratory system of lignite miners at mines in Eordea, Greece. Cases of 199 workers (Group A) residing permanently in the Eordea valley and 151 (Group B) living outside the Eordea valley were studied during Phase I and then re-examined after three years (Phase II). These cases were compared to those of 71 office workers living in Eordea valley (Group C) and to 96 living in Grevena, a region without pollution (Group D). The study included the completion of the MRC questionnaire for the detection of respiratory diseases, pulmonary function tests, measurement of diffusion capacity, otorhinolaryngologic examination, rhinomanonetry as well as chest and paranasal cavity X-rays. Chronic bronchitis was reported by 26.8%, 24.8%, 17.9% and 10.6% respectively of the subjects of groups A, B, C and D according to the answers of the questionnaire (p<0.001). The spirometry and diffusion capacity findings presented no considerable differences either in the 4 groups or between phases I and II of the study. The main problems were detected in the upper airways. A very high prevalence of severe nasal obstruction (73%, 71.2%, 55.7% and 19.3% in Groups A, B, C and D respectively) was detected. Furthermore, a high percentage of atrophic rhinitis (14%) was detected both among workers (Groups A and B) and subjects living in the Eordea valley who participated as controls (Group C). From the X-rays, hypertrophy of nasal turbinates-cartilage and polyposis was observed as follows: Group A: 53.9%, Group B: 48.1%, Group C: 46.5% and Group D: 20.3% (p<0.001). The findings related to the upper respiratory system may be due to excessive pollution by airborne particles (fly ash) pollution in the region and particularly to chromium, nickel, cobalt and lead found at high concentration levels in airborne dust. A marked association between the total air-flow in the nose and the mid-expiratory flow (p<0.01) was detected. We conclude that subjects working in lignite mines under conditions of excessive pollution by airborne contaminants have a high prevalence of atrophic rhinitis and, in addition to other standard examinations, should undergo rhinomanometry testing and X-ray imaging of the paranasal cavities.

Myotendinous junction is the muscle-tendon interface through which the contractile force can be transferred from myofibrils to the tendon extracellular matrix. At the ultrastructural level, aerobic training can modify the distal myotendinous junction of rat gastrocnemius, increasing the contact area between tissues. The aim of this work is to investigate the correlation between morphological changes and protein modulation of the myotendinous junction following moderate training. For this reason, talin, vinculin and type IV collagen amount and spatial distribution were investigated by immunohistochemistry and confocal microscopy. The images were then digitally analyzed by evaluating fluorescence intensity. Morphometric analysis revealed a significant increased thickening of muscle basal lamina in the trained group (53.1 ± 0.4 nm) with respect to the control group (43.9 ± 0.3 nm), and morphological observation showed the presence of an electron-dense area in the exercised muscles, close to the myotendinous junction. Protein concentrations appeared significantly increased in the trained group (talin +22.2%; vinculin +22.8% and type IV collagen +11.8%) with respect to the control group. Therefore, our findings suggest that moderate aerobic training induces/causes morphological changes at the myotendinous junction, correlated to the synthesis of structural proteins of the muscular basal lamina and of the cytoskeleton.

The influence of different treatment schedules of sublingual immunotherapy (SLIT) in activating IL-10-producing T-cells, crucial in inducing allergen-specific tolerance, is not completely understood. The present work was designed to evaluate allergen driven interleukin release by mononuclear cells in the early phase of SLIT, after application of different induction schemes. Twenty mite-allergic patients were enrolled, 10 (group A) treated with a traditional 98 day induction scheme and 10 (group B) with a 16 day scheme with monomeric allergoid vaccine. At the end of the induction phase, the cumulative doses taken by group A and group B patients were equivalent to 50.5 and 50.3 microg of mite group 1 allergens, respectively. The release of Th1-, Th2- and Treg-related interleukins was assessed in culture supernatants of 5 microg/ml Der-p1-stimulated mononuclear cells, isolated before and after the induction phases. No relevant treatment-related side effects were observed. Interleukin release was similar in the two groups at the enrolment. Non-stimulated and Der p 1 stimulated release of studied cytokines was similar in the two groups at enrolment. Der p 1 stimulation significantly increased IL-10 release (p<0.0002) after treatment in group B patients, and this effect was higher (p=0.05) compared to group A patients. Furthermore, at the end of SLIT induction TNF-alpha, IL-4 and IFN-gamma production were reduced in group B patients (p<0.05, p=0.062 and p=0.060, respectively). The rapid induction scheme of sublingual immunotherapy induces an early immune suppression more effectively than the slower one. The rapid induction scheme should be the preferential way to start sublingual immunotherapy, particularly when monomeric allergoids are utilized.

This study aims to quantify the prevalence of work-related musculoskeletal disorders (MSDs) and risks among male kitchen workers in the catering industry. Data were collected with the help of the Nordic musculoskeletal questionnaire and by direct observations. In total, 114 male kitchen workers from various hostels of a college in South India were considered for this study. The average age and mean years of employment of the workers are 26.4 (SD 7.7) and 7.8 respectively. The statistical analysis carried out reveals that 67.5% of male kitchen workers reported MSDs during the past 12 months. The highest prevalence rate has been found in the lower back (65.8%) and shoulder region (62.3%). Among different categories of kitchen work analyzed, it is evident that chief cooks suffer more from MSDs (79.2%) than assistant cooks (74.3%) and kitchen aides (30.0%). Workers in the older group, i.e., ≥ 41 years, and workers with 6-10 years of experience suffer with higher risk of MSDs, i.e., 93.9% and 87.5%, respectively. The male kitchen workers who participated in this research were found to possess both MSDs and ergonomic hazards.

Although long working hours have been suspected to be a risk factor for depressive symptoms (DS), it is not well understood the conditions under which long working hours are associated with it. This study investigated the moderating effect of job satisfaction on the relationship between working hours and DS. A total of 2,375 full-time non-shift day workers (73% men), aged 18–79 (mean 45) years, in 296 small- and medium-scale businesses were surveyed using a self-administered questionnaire evaluating working hours, job satisfaction, DS and covariates. The Center for Epidemiologic Studies Depression scale (CES-D) was used to assess DS. Risk of DS (CES-D ≥ 16) by working hours, job satisfaction, and both combined was estimated by multivariable logistic regression analysis. Compared to participants working 6–8 hrs/day, those working 12+ hrs/day had significantly higher odds of DS (adjusted odds ratio [aOR] 1.49), while participants with low satisfaction, as opposed to high satisfaction, had increased odds of DS (aOR 1.81). Furthermore, compared to those working 6–8 hrs/day with high satisfaction (reference group), participants working 6-8 hrs/day, > 8 to 10 hrs/day, and > 10 hrs/day combined with low satisfaction had dose-response increase of DS (aOR 1.48, 2.21 and 2.31, respectively, p < 0.05), whereas those working > 8 to 10 hrs/day and > 10 hrs/day combined with high satisfaction had not (aOR 0.93 and 1.39, respectively, p > 0.10). The results suggest that long working hours are associated with increased risk of DS only under reduced job satisfaction condition, which highlights the importance of improving job satisfaction, particularly among those working excessive hours.

Making sense of diversity in the workplace: organizational justice and language abstraction in employees' accounts of diversity-related incidents.

Roberson, Quinetta M; Stevens, Cynthia Kay

2006-03-01

To discern patterns of employee sense-making about workplace diversity, the authors analyzed 751 natural language accounts of diversity incidents from 712 workers in one department of a large organization. Six generic incident types emerged: discrimination, representation, treatment by management, work relationships, respect between groups, and diversity climates. Consistent with hypotheses, incidents that respondents viewed as negative, accounts from women, and those involving members of respondents' in-groups were more likely to cite justice issues. Partially consistent with research on the linguistic intergroup bias, both negative and positive accounts involving out-group members and accounts from men were more likely to be expressed using abstract verb forms. The authors discuss future opportunities to integrate research on diversity, justice, and the linguistic category model.

We sought to identify what abused Peruvian women want or need as intervention strategies. We conducted five focus groups with 30 women with prior or current experience with intimate partner violence. Participants noted that abused women need compassionate support, professional counseling, and informational and practical (e.g., work skills training, employment, shelter, financial support) interventions. We propose a 2-tiered intervention strategy that includes community support groups and individual professional counseling. This strategy is intended to offer broad coverage, meeting the needs of large groups of women who experience abuse, whereas providing specialized counseling for those requiring intensive support. Respect for each woman's autonomy in the decision-making process is a priority. Interventions targeted toward women and men should address structural factors that contribute to violence against women.

The aim of this work was to gain knowledge on the health status of pregnant women in Switzerland, especially their attitude to and decisions about diet, use of medication and consumption of drugs, including alcohol and tobacco. Data collected by the consecutive Swiss Health Surveys of 2007 and 2012 on sociodemographic and lifestyle characteristics (including nutrition), type and intake of medication, use of alcohol, tobacco and illicit drugs of the female population were analysed. To compare pregnant with non-pregnant women, a group of 10 times as many non-pregnant women (reference group, n = 3090) was matched with all the participating women who said they were pregnant at the time of the survey (pregnant group, n = 309). The two groups were then compared. The pregnant and non-pregnant participant groups were comparable with respect to most sociodemographic characteristics and both showed a high awareness of health-related issues. Significantly more pregnant than non-pregnant women revealed a high nutritional awareness, claiming to pay attention to what they ate (78.3 vs 73.0%). Frequent consumption of milk products and fish, and moderate consumption of meat were found more often in the pregnant group. Use of medication was comparable between the two groups, except that pregnant women took pain killers less frequently than did non-pregnant women (30.0 vs 61.5%) and relied more often on prescribed medication. Pregnant women were more restrictive in their alcohol consumption than non-pregnant women. Nevertheless, 10.0 and 1.9% of the pregnant women declared consumption of wine and beer, respectively, in the previous 7 days. Regular smoking was less frequent in the pregnant group than in the reference group (11.7 vs 30.3%) and less intensive (pregnant smokers smoked 3.6 cigarettes fewer per day). A few pregnant women (1.9%) said they consumed marijuana; no other illicit drugs were mentioned. In Switzerland, women of child-bearing age revealed high general health-awareness. During pregnancy, a considerable proportion of the women adapted their diet and seemed to refrain from using pain killers and from consuming alcohol, tobacco and illicit drugs. However, since a fairly large minority of the pregnant women mentioned drinking alcohol and/or smoking tobacco, further preventive work is needed.

To assess the mental disturbances induced by accidents at work, 41 male workers who had witnessed a fatal work accident were evaluated utilizing the criteria for posttraumatic stress disorder (PTSD) from the ICD-10 Classification of Mental and Behavioral Disorders. The Hamilton Depression Rating Scale (HDRS) was also administered to the exposed workers, as well as to 47 non-exposed construction-worker controls. The two groups were well matched with respect to age, years of employment, and years of education. They were all of Han sect; and lifestyles, incomes, and living conditions were similar. The exposed workers had a high rate of PTSD: 11 of 41 (26.8%) at one month and five of 39 (12.9%) four months after the fatal accident. The exposed groups' scores for depressive symptoms were significantly higher than those of the controls, including: 1) depressed mood, 2) guilt, 3) initial insomnia, 4) middle insomnia, 5) delayed insomnia, 6) decreased interest in work and other activities, 7) anxiety, 8) somatization, and 9) gastrointestinal symptoms (p < 0.05, p < 0.01, p < 0.001). Fatal work accidents, a major hazard in the construction industry, affect not only the victims but also the mental health of other workers. PTSD and associated emotional disorders related to exposure to serious work accidents deserve more attention for clinical and research purposes.

The objective of this study was to examine whether cognitive change and age predicted work outcome in the context of supported employment (SE) and compensatory cognitive training (CCT) in severe mental illness. Forty unemployed outpatients receiving SE (7 young [20-35 years], 15 middle-aged [36-50 years], and 18 older [51-66 years] patients) completed cognitive assessments at baseline and after 12 weeks of CCT. Logistic regression analyses showed that improvement in attention/vigilance significantly predicted work attainment (B = 2.35, SE = 1.16, p = 0.043). Young and older participants were more likely to obtain work than middle-aged participants (B = 4.03, SE = 1.43, p = 0.005; B = 2.16, SE = 0.93, p = 0.021, respectively). Improved attention and age group (young and old) were associated with better work outcomes after SE + CCT. Improving attention may be an important target for improving work outcome in severe mental illness. Middle-aged individuals may need additional support to return to work.

This study examined the association between the workplace-effort in psychosocial risk management and later employee-rating of the psychosocial work environment. The study is based on data from two questionnaire surveys - one including 1013 workplaces and one including 7565 employees from these workplaces. The association was analyzed using multi-level linear regression. The association for five different trade-groups and for five different psychosocial work environment domains was examined. Limited but statistically significant better employee-ratings of the psychosocial work environment in the respective domains were observed among Danish workplaces that prioritized "development possibilities for employees," "recognition of employees," "employees influence on own work tasks," good "communication at the workplace," and "help to prevent work overload." Danish workplaces with a high effort in psychosocial risk management in the preceding year had a small but significantly more positive rating of the psychosocial work environment by the employees. However, future studies are needed to establish the causality of the associations.

This study compared maximal strength training (MST) with equal training volume (kg × sets × repetitions) of conventional strength training (CON) primarily with regard to work economy, and second one repetition maximum (1RM) and rate of force development (RFD) of single leg knee extension. In an intra-individual design, one leg was randomized to knee-extension MST (4 or 5RM) and the other leg to CON (3 × 10RM) three times per week for 8 weeks. MST was performed with maximal concentric mobilization of force while CON was performed with moderate velocity. Eight untrained or moderately trained men (26 ± 1 years) completed the study. The improvement in gross work economy was -0.10 ± 0.08 L min(-1) larger after MST (P = 0.011, between groups). From pre- to post-test the MST and CON improved net work economy with 31 % (P < 0.001) and 18 % (P = 0.01), respectively. Compared with CON, the improvement in 1RM and dynamic RFD was 13.7 ± 8.4 kg (P = 0.002) and 587 ± 679 N s(-1) (P = 0.044) larger after MST, whereas isometric RFD was of borderline significance 3,028 ± 3,674 N s(-1) (P = 0.053). From pre- to post-test, MST improved 1RM and isometric RFD with 50 % (P < 0.001) and 155 % (P < 0.001), respectively whereas CON improved 1RM and isometric RFD with 35 % (P < 0.001) and 83 % (P = 0.028), respectively. Anthropometric measures of quadriceps femoris muscle mass and peak oxygen uptake did not change. In conclusion, 8 weeks of MST was more effective than CON for improving work economy, 1RM and RFD in untrained and moderately trained men. The advantageous effect of MST to improve work economy could be due to larger improvements in 1RM and RFD.

Lifestyle behaviors significantly impact health, yet remain poorly defined in Chinese rural-to-urban migrants. In a cross-sectional study of health-related behaviors of 5484 rural-to-urban migrants who had worked in Shanghai for at least six months, we assessed the contribution of demographics and physical and mental health to lifestyle behaviors in male and female participants by multiple stepwise cumulative odds logistic regression. Respondents were 51.3% male. 9.9% exhibited abnormal blood pressure; 27.0% were overweight or obese; 11.2% reported abnormal mental health; 36.9% reported healthy lifestyle. Multiple stepwise cumulative odds logistic regression indicated that men working in manufacturing reported less unhealthy lifestyle than those in hospitality (cumulative odds ratio (COR) = 1.806, 95%CI 1.275-2.559) or recreation/leisure (COR = 3.248, 95%CI 2.379-4.435); and women working in manufacturing and construction reported less unhealthy lifestyle than those in all other sectors. Unhealthy lifestyle was associated with small workplaces for men (COR = 1.422, 95%CI 1.154-1.752), working more than 8 or 11 hours per day for women and men, respectively, and earning over 3500 RMB in women (COR = 1.618, 95%CI 1.137-2.303). Single women and women who had previously resided in three or more cities were more likely to report unhealthy lifestyle (COR = 2.023, 95%CI 1.664-2.461, and COR = 1.311, 95%CI 1.072-1.602, respectively). Abnormal mental status was also correlated with unhealthy lifestyle in men (COR = 3.105, 95%CI 2.454-3.930) and women (COR = 2.566, 95%CI 2.024-3.252). There were different risk factors of unhealthy lifestyle score in male and female rural-to-urban migrants, especially in number of cities experienced, salary, marital status, work place scale. Several demographic groups: employment sectors (e.g. hospitality and recreation/leisure), working conditions (e.g. long hours) and abnormal mental status were associated with unhealthy lifestyle behaviors in Chinese rural-to-urban migrants, and health interventions should be targeted to these groups.

The Department of Earth Sciences, Durham University, has a balanced gender profile at undergraduate, postgraduate and postdoctoral levels (38%, 42% and 45% females, respectively), but one of the lowest percentages, relative to the natural applicant pool, of female academic staff amongst UK geoscience departments. There are currently 9% female academic staff at Durham, compared with a median value (in November 2015) of 20% for all Russell Group geoscience departments in the UK. Despite the fact that the female staff group is relatively senior, the Department's current academic management is essentially entirely male. The Department has an informal working culture, in which academics operate an "open door" policy, and staff and students are on first name terms. This culture, open plan office space, and our fieldwork programme, allow staff and students to socialise. A positive outcome of this culture is that > 95% of final year undergraduate students deemed the staff approachable (National Student Survey 2016). Nevertheless, a survey of staff and research student attitudes revealed significant differences in the way males and females perceive our working environment. Females are less likely than males to agree with the statements that "the Department considers inappropriate language to be unacceptable" and "inappropriate images are not considered acceptable in the Department". That anyone could find "inappropriate" language and images "acceptable" is a measure of the challenge faced by the Department. Males disagree more strongly than females that they "have felt uncomfortable because of [their] gender". The Department is proactively working to improve equality and diversity. It held a series of focus group meetings, divided according to gender and job role, to understand the differences in male and female responses. Female respondents identified examples of inappropriate language (e.g. sexual stereotyping) that were directed at female, but not male, colleagues. Males recognised the unacceptability of inappropriate language, but were unsure how it is defined. These differences have serious implications for professional relationships in our department, in which males occupy all positions of managerial authority and most academic positions. Such asymmetric relationships make it difficult for students and junior staff to challenge inappropriate behaviour. The Department will hold a workshop for all staff, and student representatives, facilitated by the University's Centre for Academic, Researcher & Organisational Development, on "Professionalism and Respecting Diversity in Earth Sciences". The objectives are to: 1) define the boundaries between informality and inappropriate behaviour in office, laboratory and fieldwork environments; 2) encourage all colleagues to reflect on their own behaviours; and 3) develop a culture to empower individuals to intervene where inappropriate behaviour occurs. Outcomes of the workshop will be discussed in this presentation. Our immediate aim is to encourage positive change whilst preserving the best aspects of our open door culture. Longer term, we hope that by fostering a positive working environment, we will encourage outstanding female academics to work at Durham. The Department's objective is to achieve the average gender balance of the Russell Group geoscience departments over a period of 10 years.

Peripheral nerve block is an accepted method in lower limb surgeries regarding its convenience and good tolerance by the patients. Quick performance and fast sensory and motor block are highly demanded in this method. The aim of the present study was to compare 2 different methods of sciatic and tibial-peroneal nerve block in lower limb surgeries in terms of block onset. In this clinical trial, 52 candidates for elective lower limb surgery were randomly divided into 2 groups: sciatic nerve block before bifurcation (SG; n = 27) and separate tibial-peroneal nerve block (TPG; n = 25) under ultrasound plus nerve stimulator guidance. The mean duration of block performance, as well as complete sensory and motor block, was recorded and compared between the groups. The mean duration of complete sensory block in the SG and TPG groups was 35.4 ± 4.1 and 24.9 ± 4.2 minutes, respectively, which was significantly lower in the TPG group (P = 0.001). The mean duration of complete motor block in the SG and TPG groups was 63.3 ± 4.4 and 48.4 ± 4.6 minutes, respectively, which was significantly lower in the TPG group (P = 0.001). No nerve injuries, paresthesia, or other possible side effects were reported in patients. According to the present study, it seems that TPG shows a faster sensory and motor block than SG.

Purpose This study assesses how well two cartoons transfer knowledge of principles of work disability prevention among stakeholders, according to their level of experience. We also document stakeholders' perceptions of the usefulness of the cartoons. Method We performed a descriptive study. Two groups of stakeholders were recruited: (1) experienced (working for more than 2 years in work disability), (2) non-experienced (in training). A self-administered questionnaire with open-ended questions documented stakeholders' understanding of each cartoon box and their perception of the possible usefulness of the cartoons. We transformed qualitative responses into quantitative responses for descriptive purposes. We performed independent t tests to compare the groups' level of understanding, and content analysis for the perception of usefulness. Results Overall, 149 stakeholders (50 experienced and 99 non-experienced) participated and identified 79.4 and 61.4 % of all principles presented in each of the two cartoons respectively. Experienced stakeholders identified more principles compared to non-experienced stakeholders (p = 0.007). Both cartoons were perceived to be useful for knowledge transfer. Conclusions Principles were generally well identified in the cartoons by all participants. Cartoons can be used as an effective tool among stakeholders to achieve a common understanding in order to coordinate their actions.

A questionnaire ('Dutch Musculoskeletal Questionnaire', DMQ) for the analysis of musculoskeletal workload and associated potential hazardous working conditions as well as musculoskeletal symptoms in worker populations is described and its qualities are explored using a database of 1575 workers in various occupations who completed the questionnaire. The 63 questions on musculoskeletal workload and associated potentially hazardous working conditions can be categorized into seven indices (force, dynamic and static load, repetitive load, climatic factors, vibration and ergonomic environmental factors). Together with four separate questions on standing, sitting, walking and uncomfortable postures, the indices constitute a brief overview of the main findings on musculoskeletal workload and associated potentially hazardous working conditions. Homogeneity of the indices is satisfactory. The divergent validity of the indices is fair when compared with an index of psychosocial working conditions and discomfort during exposure to physical loads. Worker groups with contrasting musculoskeletal loads can be differentiated on the basis of the indices and other factors. With respect to the concurrent validity, it appears that most indices and factors show significant associations with low back and/or neck-shoulder symptoms. This questionnaire can be used as a simple and quick inventory for occupational health services to identify worker groups in which a more thorough ergonomic analysis is indicated.

Analysing the relationship between gender and memory, and examining the effects of age on the overall memory-related functioning, are the ongoing goals of psychological research. The present study examined gender and age group differences in episodic memory with respect to the type of task. In addition, these subgroup differences were also analysed in visual working memory. A sample of 366 women and 330 men, aged between 16 and 69 years of age, participated in the current study. Results indicate that women outperformed men on auditory memory tasks, whereas male adolescents and older male adults showed higher level performances on visual episodic and visual working memory measures. However, the size of gender-linked effects varied somewhat across age groups. Furthermore, results partly support a declining performance on episodic memory and visual working memory measures with increasing age. Although age-related losses in episodic memory could not be explained by a decreasing verbal and visuospatial ability with age, women's advantage in auditory episodic memory could be explained by their advantage in verbal ability. Men's higher level visual episodic memory performance was found to result from their advantage in visuospatial ability. Finally, possible methodological, biological, and cognitive explanations for the current findings are discussed.

Floquet topological phases with symmetry in all dimensions

Dynamical systems may host a number of remarkable symmetry-protected phases that are qualitatively different from their static analogs. In this work, we consider the phase space of symmetry-respecting unitary evolutions in detail and identify several distinct classes of evolution that host dynamical order. Using ideas from group cohomology, we construct a set of interacting Floquet drives that generate dynamical symmetry-protected topological order for each nontrivial cohomology class in every dimension, illustrating our construction with explicit two-dimensional examples. We also identify a set of symmetry-protected Floquet drives that lie outside of the group cohomology construction, and a further class of symmetry-respecting topological drives which host chiral edge modes. We use these special drives to define a notion of phase (stable to a class of local perturbations in the bulk) and the concepts of relative and absolute topological order, which can be applied to many different classes of unitary evolutions. These include fully many-body localized unitary evolutions and time crystals.

[1] proposed a novel analysis and forecast method of electricity business expansion based on Seasonal Adjustment, we extend this work to include the effect the micro and macro aspects, respectively. From micro aspect, we introduce the concept of load factor to forecast the stable value of electricity consumption of single new consumer after the installation of new capacity of the high-voltage transformer. From macro aspects, considering the growth of business expanding is also stimulated by the growth of electricity sales, it is necessary to analyse the antecedent relationship between business expanding and electricity sales. First, forecast electricity consumption of customer group and release rules of expanding capacity, respectively. Second, contrast the degree of fitting and prediction accuracy to find out the antecedence relationship and analyse the reason. Also, it can be used as a contrast to observe the influence of customer group in different ranges on the prediction precision. Finally, Simulation results indicate that the proposed method is accurate to help determine the value of expanding capacity and electricity consumption.

Identify the perceptions of perianesthesia nurses regarding behaviors that promote or detract from sustaining a safe, efficient, and satisfying work environment. Two focus groups and seven individual interviews (n=14) were conducted exploring the perceptions regarding team behavior of registered nurses in one pediatric perianesthesia unit. Qualitative descriptive data collection, inductive content analysis. Nurses described a responsive, engaged health care team whose leadership is available and directive when needed, as creating an effective, satisfying work environment. Primary themes that emerged were Leadership Sets the Tone, Playing Fair, No One Gets Hurt, and Why We Stay. This nursing team acknowledged that inattentive, distracted team members cause frustration, work inequities, and care delays, potentially undermining patient safety. Results demonstrate the need to create and sustain consistently respectful perianesthesia work cultures. Research focusing on unit specific approaches to work distribution, communication, leadership, and technology use is needed. Copyright © 2016 American Society of PeriAnesthesia Nurses.

The aim of this study was to explore and reflect upon mental health nursing and first-episode psychosis. Seven multidisciplinary focus group interviews were conducted, and data analysis was influenced by a grounded theory approach. The core category was found to be a process named 'working behind the scenes'. It is presented along with three subcategories: 'keeping the patient in mind', 'invisible care' and 'invisible network contact'. Findings are illuminated with the ethical principles of respect for autonomy and paternalism. Nursing care is dynamic, and clinical work moves along continuums between autonomy and paternalism and between ethical reflective and non-reflective practice. 'Working behind the scenes' is considered to be in a paternalistic area, containing an ethical reflection. Treating and caring for individuals experiencing first-episode psychosis demands an ethical awareness and great vigilance by nurses. The study is a contribution to reflection upon everyday nursing practice, and the conclusion concerns the importance of making invisible work visible.

[Fundamental principles of social work--(also) a contribution to public health ethics].

PubMed

Lob-Hüdepohl, A

2009-05-01

Social work and public health are different but mutually connected. Both are professions with their own ethical foundations. Despite all differences, they have the same goal: to protect and to enhance the well-being of people. This is, in part, why the fundamental ethical principles of social work are salient for developing public health ethics. As a human rights profession, social work respects the personal autonomy of clients, supports solidarity-based relationships in families, groups or communities, and attempts to uphold social justice in society. Social workers need to adopt special professional attitudes: sensibility for the vulnerabilities of clients, care and attentiveness for their resources and strengths, assistance instead of paternalistic care and advocacy in decision making for clients' well-being when clients are not able to decide for themselves. These fundamental ethical principles are the basis for discussion of special topics of social work ethics as public health ethics, for example, in justifying intervention in individual lifestyles by public services without the participation or consent of the affected persons.

The aim of this study was to examine the relationship between occupation and sleep duration, sleepiness, insufficient sleep, and insomnia in day and shift workers (including night work and watches). The study was population-based and cross-sectional, and relied on self-administered questionnaires. It was conducted as part of the 1997-1999 Hordaland Health Study in collaboration with the Norwegian National Health Screening Service. Aged 40-45 years, 7782 participants answered a sleep questionnaire, reporting their occupation and whether or not they were employed in shift work. Our study found differences in sleep duration during the working week between occupational groups; in both shift and day workers. Craft workers, plant operators, and drivers slept less than leaders, and non-personal and personal service workers. Within some occupations (leaders, personal service workers, and plant operators), shift workers slept less than day workers. The mean sleep duration of shift workers was 15 minutes shorter than that of day workers. Rise times, but not bedtimes, were earlier in craft-and construction workers, plant operators, and drivers than in leaders and non-personal and personal service workers, particularly day workers. When adjusted for shift work and working hours - compared to leaders - craft workers, plant operators, and drivers had an increased risk of daytime sleepiness (odds ratio 1.5, 1.8, and 1.8 respectively) and of falling asleep at work (odds ratio 1.6, 2.1 and 2.0 respectively). Shift workers had an increased risk of falling asleep at work and insomnia. Occupation has separate effects on sleep duration and sleep-related problems, independent of the effects of shift work.

The aim of this work was the analysis of singlet oxygen and the ozone effect on lipid peroxidation and antioxidant activity of rat organs and blood. Wistar rats were randomly divided into five groups: control group (without any manipulations; n = 10) and four main groups (n = 10 in each group) with inhalations by dry, moisture and oil-processed ozone-oxygen mixture (ozone concentration 60 micro g/l) or singlet oxygen, respectively. Activity of pro- and antioxidant systems was estimated in blood and tissues (lungs, heart, liver and kidney) by inducing biochemiluminescence. Singlet oxygen was shown to exert the "mildest" effect with stimulation of blood antioxidant potential and saving tissue oxidative potential without hyperactivation of lipid peroxidation. Use of moistened ozone-oxygen mixture caused moderate stimulating action on antioxidant re serves of blood and tissues. Dry ozone-oxygen mixture clearly decreased lipid peroxidation intensity.

Group Theoretical Characterization of Wave Equations

NASA Astrophysics Data System (ADS)

Nisticò, Giuseppe

2017-12-01

Group theoretical methods, worked out in particular by Mackey and Wigner, allow to attain the explicit Quantum Theory of a free particle through a purely deductive development based on symmetry principles. The extension of these methods to the case of an interacting particle finds a serious obstacle in the loss of the symmetry condition for the transformations of Galilei's group. The known attempts towards such an extension introduce restrictions which lead to theories empirically too limited. In the present article we show how the difficulties raised by the loss of symmetry can be overcome without the restrictions that affect tha past attempts. According to our results, the different specific forms of the wave equation of an interacting particle are implied by particular first order invariance properties that characterize the interaction with respect to specific sub-groups of galileian transformations. Moreover, the possibility of yet unknown forms of the wave equation is left open.

To determine the prevalence of myopia in the adult populations of two different ethnic communities in the Ecuadorian Amazon. Refraction with retinoscopy after cycloplegia was performed for 507 Naporuna (an ethnic group indigenous to the jungles of the Ecuadorian Amazon) and for 776 settlers (white-mestizos from the Andes, now living in the Amazon and working for the petroleum industry). Ages ranged from 18 to 45 years. All subjects had little or no formal education. The prevalence of myopia was 4.7% among the Naporuna and 5.5% among the settlers; the prevalence of hyperopia was higher, at 17.8% and 36.0%, respectively. The prevalence of myopia in the two communities studied agrees with the results of other studies showing a low prevalence of myopia among groups with low levels of formal education or groups living a nonurban lifestyle.

To study systematically the separate and combined effects of work stress and socioeconomic position on three measures of health in an unselected working population. Two exposures (high demand/low control ("job strain"); effort-reward imbalance at work) are related to angina pectoris, depression, and poor self-rated health in a cross-sectional study design in which socioeconomic position was measured by occupational position and educational level. Baseline data of a prospective population-based cohort study in Germany, collected between 2000 and 2003. 1749 employed or self-employed men and women (36.3% of total sample) aged 45-65 years. Effort-reward imbalance and job strain were associated with elevated odds ratios of all three health measures, using logistic regression analysis. The prevalence of poorer health was always highest in subgroups defined by high work stress and low socioeconomic position, with respective odds ratios ranging from 2.30 to 2.98 (95% CI 1.38 to 4.52) for self-rated health, 1.70 to 2.24 (95% CI 1.04 to 3.88) for angina and 2.61 to 8.20 (95% CI 1.53 to 14.15) for depression. Although stress at work was related to poorer health in the total study group, the strongest associations were consistently observed in men and women with low educational level or low occupational position. Worksite health promotion should be directed primarily towards these target groups.

Flight controllers of the International Space Station (ISS) are engaged in shift work to provide 24-h coverage to support ISS systems. The purpose of this study was to investigate the prevalence and associated factors of shift work sleep disorder (SWSD) among Japanese ISS flight controllers. A questionnaire study was conducted using the Standard Shiftwork Index to evaluate sleep-related problems and possible associated variables. Among 52 respondents out of 73 flight controllers, 30 subjects were identified as night shift workers who worked 3 or more night shifts per month. Those night shift workers who answered "almost always" to questions about experiencing insomnia or excessive sleepiness in any case of work shifts and days off were classified as having SWSD. Additionally, 7 night shift workers participated in supplemental wrist actigraphy data collection for 7 to 8 days including 3 to 4 days of consecutive night shifts. Fourteen of 30 night shift workers were classified as having SWSD. Significant group differences were observed where the SWSD group felt that night shift work was harder and reported more frequent insomniac symptoms after a night shift. However, no other variables demonstrated remarkable differences between groups. Actigraphy results characterized 5 subjects reporting better perceived adaptation as having regular daytime sleep, for 6 to 9 h in total, between consecutive night shifts. On the other hand, 2 subjects reporting perceived maladaptation revealed different sleep patterns, with longer daytime sleep and large day-to-day variation in daytime sleep between consecutive night shifts, respectively. As the tasks for flight control require high levels of alertness and cognitive function, several characteristics, namely shift-working schedule (2 to 4 consecutive night shifts), very short break time (5 to 10 min/h) during work shifts, and cooperative work with onboard astronauts during the evening/night shift, accounted for increasing workloads especially in the case of night shifts, resulting in higher or equal prevalence of SWSD to that among other shift-working populations. Further studies are required to collect more actigraphy data and examine the possibility of interventions to improve SWSD.

Objectives To support sustainability of the welfare society enhanced work retention is needed among those with impaired work ability. Partial health-related benefits have been introduced for this target. The aim was to estimate the effects of partial sick leave on transition to disability pension applying propensity score methods. Design Register-based cohort study. Setting Sample from the national sickness insurance registers representative of the Finnish working population (full-time workers) with long-term sickness absence due to musculoskeletal disorders, mental disorders, traumas or tumours. Participants All recipients of partial or full sickness benefit whose sick leave period had ended between 1 May and 31 December 2007 were included. The sample was limited to four most prevalent diagnostic groups—mental and musculoskeletal disorders, traumas and tumours. The total sample consisted of 1047 subjects on partial sick leave (treatment group) and 28 380 subjects on full sick leave (control group). A subsample (1017 and 25 249 subjects, respectively) was formed to improve the comparability of the two groups. Outcome measures A three-category measure and a binary measure for the occurrence of disability pension on the last day of 2008 were computed. Results Partial sickness benefit reduced the risk (change in absolute risk) of full disability pension by 6% and increased the risk of partial disability pension by 8% compared with full sick leave. The effects did not differ markedly for the two main diagnostic groups of musculoskeletal and mental disorders. In men, the use of full disability pension was reduced by 10% with a 5% increase in the use of partial disability pension, while in women the effects were close to those of the total sample. Conclusions Our findings suggest that combining work with partial sick leave may provide one means to increase work retention at population level. The use of partial sick leave could be encouraged among men. PMID:23144260

To assess the effect of thalidomide on Trinitrobenzensulphonic acid (TNBS)-induced or oxazolone-induced colitis and discuss the possible mechanism of its action. Transmural colitis was induced by TNBS in three groups of rats (n=6 each), and distal colitis was induced by oxazolone in three groups of rats (n=6 each). Then the rats of the groups were treated with thalidomide [200 mg/(kg x d)], prednisone [5 mg/(kg x d)] or vehicle (olive oil) respectively by oral gavage. The colitis was allowed to run its course for 7 d after gavage and at that time the following endpoints were assessed. Colitis was evaluated by macroscopic and microscopic score; the expression of NF-kappaB P65 was examined by immunohistchemical (IHC); the expression of TNF-alpha mRNA was assayed by hybridization in situ (ISH); the cytokine TNF-alpha, IL-4, IFN-gamma were estimated by enzyme-linked immunoadsordent assay (ELISA). With respect to TNBS model, in the control, prednisone-treatment and thalidomide-treatment groups, the macroscopic and microscopic scores were 6.33 +/- 1.03, 1.67 +/- 0.82, 2.00 +/- 0.89 and 7.33 +/- 1.03, 2.67s +/- 0.82, 3.17 +/- 0.75 respectively; the expression levels of NF-kappaB P65 and TNF-alpha mRNA in the three groups were 62.45 +/- 12.38, 23.62 +/- 8.54, 34.18 +/- 9.65 and 12.42 +/- 4.63, 9.86 +/- 3.29, 4.35 +/- 1.74 respectively; the levels of TNF-alpha, IL-4, IFN-gamma were 540.32 +/- 80.76, 94.58 +/- 14.45, 486.18 +/- 68.47; 396.53 +/- 92.42, 78.45 +/- 12.69, 347.56 +/- 82.94; and 385.68 +/- 88.57, 123.68 +/- 38.15, 378.27 +/- 90.65 respectively. The results indicated that thalidomide treatment significantly reduced colonic inflammation, suppressed NF-kappaB activation,enhanced TNF-alpha mRNA degradation, inhibited the synthesis of the TNF-alpha, IEN-gamma and increased the production of IL-4. However, with respect to oxazolone model, the macroscopic score and microscopic score were 2.00 +/- 0.89, 0.33 +/- 0.52, 1.83 +/- 0.75 and 7.83 +/- 1.47, 3.33 +/- 0.82, 6.50 +/- 1.22 respectively. Thalidomide appeared not to be effective in reducing the oxazolone-induced chronic colitis. Thalidomide may be proposed as a useful drug for Crohn's disease, but further work is needed to clarify whether it is an efficacious agent for ulcerative colitis.

Background Shift work is indicated to be associated with adverse metabolic disorders. However, potential effects of shift work on metabolic syndrome (MetS) and its components have not been well established. Methods In total, 26,382 workers from Dongfeng-Tongji Cohort were included in this study. Information on shift work history was gathered through questionnaires and metabolic traits were measured. Logistic regression models were used to calculate the odds ratio (OR) and 95% confidence interval (CI) for long-term shift work related with MetS and each component, respectively. Further stratification analysis was performed to detect the differences on MetS between female and male shift workers. Results Long-term shift work was associated with MetS without adjusting for any confounders. Compared with the group of non-shift work, the multivariate-adjusted ORs (95%CI) of MetS associated with 1–10, 11−20, and ≥20y of shift work were 1.05 (0.95−1.16), 1.14 (1.03−1.26), 1.16 (1.01−1.31), respectively. In female workers, we found a dose-response relationship that every 10 years increase in shift work was associated with a 10% (95% CI: 1%−20%) elevated OR of MetS, while no significant dose-response trend was found among male workers. Furthermore, shift work duration was significantly associated with ORs of high blood pressure (1.07, 1.01−1.13), long waist circumference (1.10, 1.01−1.20) and high glucose levels (1.09, 1.04−1.15). No significant association was observed between shift work and low HDL cholesterol) and raised triglyceride levels. Conclusions Long-term shift work was associated with metabolic syndrome and the association might differ by gender in retired workers. Applicable intervention strategies are needed for prevention of metabolic disorders for shift workers. PMID:25761114

In many countries around the world, negative changes in lifestyles are observed. The aim of this study was to analyze the influence of selected lifestyle indicators on work ability among professionally active individuals. The study was performed in the randomly selected group of full-time employees (94 men and 93 women) living in the city of Lódź. Work ability was measured with the work ability index and lifestyle characteristic was assessed with the healthy lifestyle index. We analyzed four lifestyle indicators: non-smoking, healthy weight, fiber intake per day, and regular physical activity. Logistic regression was used to estimate odds ratios and 95% confidence intervals to control the effects of lifestyle and work ability. The analysis of lifestyle index indicated that 27.7, 30.9, 27.7 and 11.7% of men and 15.1, 21.5, 35.5 and 26.9% of women scored 0, 1, 2, 3 points, respectively. Only 2.1% of men and 1.1% of women met the criteria for the healthy lifestyle (score 4). Work ability was excellent, good and moderate in 38.3, 46.8 and 14.9% of men, and in 39.8, 14.9 and 19.3% of women, respectively. Poor work ability was found in 9.7% women. Work ability was strongly associated with lifestyle in both men and women. Among men with index score = 0, the risk of moderate work ability was nearly seven times higher than in men whose lifestyle index score exceeded 1 or more points (OR = 6.67; 95% CI: 1.94-22.90). Among women with lifestyle index score = 0, the risk of moderate or lower work ability was also highly elevated as compared to those with lifestyle index = 1 or higher (OR = 14.44; 95% CI: 3.53-59.04). Prophylactic schedules associated with the improvement of lifestyles should be addressed to all adults. Future programs aimed at increasing work ability should consider work- and lifestyle-related factors.

Emotional intelligence as a moderator in the stress-burnout relationship: a questionnaire study on nurses.

PubMed

Görgens-Ekermans, Gina; Brand, Tamari

2012-08-01

To investigate inter-relationships between emotional intelligence (EI), work stress and burnout in a group of nurses in the Western Cape Province, South Africa. The moderating effect of EI in the stress-burnout relationship and group differences (nurses working in different wards) in burnout were also investigated. Stress and subsequent burnout commonly threaten the occupational health and well-being of nurses in South Africa and elsewhere. Developing EI in nurses may increase individual stress resistance and combat burnout. A cross-sectional research design with anonymous questionnaires was conducted. Self-report data were used. Survey data were collected from 122 nurses working in different wards at four hospitals from a private hospital group. The Swinburne University Emotional Intelligence Test, Sources of Work Stress Inventory and Maslach Burnout Inventory were used to measure EI, stress and burnout, respectively. Consistent inverse relationships between emotional control and management as dimensions of EI, and stress and burnout emerged. A differential effect of high vs. low EI on the stress-burnout relationship was evident. Workload and the work/family interface emerged as significant predictors of burnout. Respondents working in maternity, paediatric and ER wards reported more feelings of personal accomplishment than those working in general wards. Higher EI is significantly related with lower stress and burnout in a sample of South African nurses. The moderator effect of EI in the stress-burnout relationship suggests that enhanced EI may help diminish burnout development when chronic stress is experienced. EI developmental interventions, if introduced in nursing curricula, may increase emotional coping resources and enhanced social skills, which may benefit the long-term occupational health of nurses. This may be relevant in developing countries, where environmental stressors related to the organisational context (budget constraints) and wider social factors (shortage of qualified nurses) are difficult to address. © 2012 Blackwell Publishing Ltd.

The following study analyses the influence of risk factors among the occupational group of truck drivers on postural control and body mass index (BMI). Observational study. One motorway station close to several highways in Germany. 180 truck drivers (177 male/3 female), aged 21-65 years old, took part in this study. Postural control was examined using a pressure plate. In order to examine the influence of body weight (BMI) and working years on postural control, subjects were divided into samples of five and three groups, respectively. Furthermore, it was evaluated whether the subjects suffered from back pain. For data analysis, the Kruskal-Wallis test was used as the data were not normally distributed. Once the p value of the Kruskal-Wallis test was p≤0.05, the Conover-Iman comparison and afterwards the Bonferroni-Holm correction were used. The significance level was set at α ≤0.05. Regarding the number of working years, a significant increase of frontal (p≤0.04) and sagittal (p≤0.001) sway were observed. The correlation of the five BMI groups with the number of working years demonstrates that an increase of the working years leads to an increase of BMI (p≤0.03). Furthermore, the majority of truck drivers participating in this study suffered from back pain (61.7%). BMI and musculoskeletal impairment are indicators of health risk factors. In this study, it is shown that an increasing number of working years and an increasing BMI lead to a decrease in frontal and sagittal postural sway. In addition, the number of working years correlates with body weight and back pain. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

In 1972, Dr. Bhaskar Rao 1st worked for Operations Research Group (ORG), a market research agency. He resigned as its President in December 1991 after it was sold to Business India. He was able to life ORG from just an audit organization to an organization that could conduct analyses and formulate strategies, and that was doing well financially. He was not willing to let this well-respected, independent, professional, and nonprofit group be viewed as part of a for-profit magazine company, however. After finishing his undergraduate education, he became involved in the social service organization directed by Nehru. In 1962, he worked full time for its mass awareness group and then worked to combat rumors during the India-China war. In 1963, he worked with farmers to educate them on how to use fertilizers to increase yield. This experience brought him a scholarship to study social science at Kansas State University in 1967. In the US, he took a course at Martin Luther King's School for Social Change to further his political interests. He received a Ph.D. in mass communications from the University of Iowa then returned to India. In 1970, he worked for the Ford Foundation as a consultant to the Ministry of Health and Family Planning which wanted to survey 25,000 people to learn their perceptions of family planning. He dealt with ORG. The owner convinced him to leave the Ford Foundation and work for ORG where he worked on the family planning survey and the national readership survey. In 1973, he challenged remarks made by the minister of information and broadcast during a public speech. Impressed, the minister offered him an evaluation advisor position. In 1977, however, he left and returned to ORG where he became widely known as a media analyst. In 1983, he became vice president of ORG and president in 1985.

Twelve-hour shift systems have become more popular in industry. Survey data of shift length, shift rotation speed, self-rated sleep, satisfaction and perceived health were investigated for the associations among 599 predominantly male Finnish industrial employees. The studied forward-rotating shift systems were 12-h fast (12fast, DDNN------, n = 268), 8-h fast (8fast, MMEENN----, n = 161) and 8-h slow (8slow, MMMM-EEEE-NNNN, n = 170). Satisfaction with shift system differed between the groups (p < 0.01) after controlling for age, gender, shift work experience and self-rated stress. In the 12fast, 98% of employees were satisfied with their shift system (75% 8fast, 54% 8slow). Negative effects on sleep and alertness were rare (8%) in the 12fast group (53% 8fast, 66% 8 slow, p < 0.01) and self-reported sleep difficulties were less frequent than in the 8fast and 8slow groups (8%, 27%, 41%, respectively, p < 0.01). The self-reported average sleep duration (12fast 7:50, 8fast 7:24, 8slow 7:15, p < 0.01), and shift-specific sleep before and between morning shifts and after first night shift were longer in the 12fast group. Perceived negative effects of the current shift system on general health (12fast 4%, 8fast 30%, 8slow 41%, p < 0.001) and work-life balance (12fast 8%, 8fast 52%, 8slow 63%, p < 0.001) differed strongly between the groups. In conclusion, the perceived effects of shift work were dependent on both shift length and shift rotation speed: employees in the 12-h rapidly forward-rotating shift system were most satisfied, perceived better work-life balance and slept better than the employees in the 8fast or especially the employees in the 8-h slowly rotating systems.

The present study combined a time-locked paradigm and high-time-resolution event-related potential (ERP) recordings to examine different phases of working memory, including early visual processing and late memory-related processes of encoding, maintenance, and retrieval, in 67 adults with schizophrenia and 46 healthy controls. Alterations in ERP components were correlated with task performance. Patients performed significantly worse in the working memory task than healthy subjects, although all subjects' accuracy exceeded 80%. During encoding, the N1 and P2 component amplitudes were lower while the P300 amplitude was higher in schizophrenic patients compared to healthy controls. There were no differences between groups with respect to the mean amplitudes of the negative slow waves in the early stage (the first 400 ms) of the maintenance phase. However, in the next 500-ms time window, the patients exhibited a more negative deflection in the middle fronto-central region than the control group. Likewise, a similar pattern was observed in the second 500-ms period in the middle fronto-central region, although the effect was marginally significant. There were no differences between groups in the remaining 1000 ms. During retrieval, the P1, N1 and P2 amplitudes were lower while the P300 amplitude and latency were higher in schizophrenic patients. The present results indicate early visual deficits in the working memory task in adults with schizophrenia. Impairments in the maintenance phase were confined to the late rehearsal stage. The increased P300 amplitude at the fronto-central electrode sites along with the poorer behavioral performance suggests that schizophrenic patients have an inefficient working memory system.

Abstract Background: Tamoxifen is the most widely used drug for treating patients with estrogen receptor-sensitive breast cancer. There is evidence that breast cancer patients treated with tamoxifen exhibit cognitive dysfunction. However, the underlying neural mechanism remains unclear. The present study aimed to investigate the neural mechanisms underlying working memory deficits in combination with functional connectivity changes in premenopausal women with breast cancer who received long-term tamoxifen treatment. Methods: A total of 31 premenopausal women with breast cancer who received tamoxifen and 32 matched healthy control participants were included. The participants completed n-back tasks and underwent resting-state functional magnetic resonance imaging, which measure working memory performance and brain functional connectivity, respectively. A seed-based functional connectivity analysis within the whole brain was conducted, for which the dorsolateral prefrontal cortex was chosen as the seed region. Results: Our results indicated that the tamoxifen group had significant deficits in working memory and general executive function performance and significantly lower functional connectivity of the right dorsolateral prefrontal cortex with the right hippocampus compared with the healthy controls. There were no significant changes in functional connectivity in the left dorsolateral prefrontal cortex within the whole brain between the tamoxifen group and healthy controls. Moreover, significant correlations were found in the tamoxifen group between the functional connectivity strength of the dorsolateral prefrontal cortex with the right hippocampus and decreased working memory performance. Conclusion: This study demonstrates that the prefrontal cortex and hippocampus may be affected by tamoxifen treatment, supporting an antagonistic role of tamoxifen in the long-term treatment of breast cancer patients.

To explore the prevalence of the use of hypnotics and sedatives in a sample of the Spanish working population and to examine its association with certain work-related stress factors. Using data from the 2007 Spanish Household Survey on Alcohol and Drugs (Encuesta Domiciliaria sobre Alcohol y Drogas en España [EDADES]), we analyzed the distribution of the use of hypnotics and sedatives in the previous month in the working population aged 16 to 64 years old (n=13,005). Associations with exposure to certain work-related stress factors (noxious working environment, precariousness, workload, and social support) were examined using logistic regression modelling. The prevalence of the use of hypnotics and sedatives among women in the previous month doubled that of men (6.5% and 3.3%, respectively), while use among the oldest age group was twice that of the youngest group in both sexes (10.2% in women and 5.5% in men older than 45 years), and was four times higher among those reporting poor health (18.9% in women and 11% in men). Concerning work-related stress, exposure to moderate (OR: 1.96; 95%CI: 1.31-2.92) and high (OR: 1.95; 95%CI: 1.14-3.34) levels of precariousness in men and moderate levels in women (OR: 1.43; 95%CI: 1.03-1.99) was associated with the use of hypnotics and sedatives. The prevalence of the use of hypnotics and sedatives was high in women and in workers older than 45 years. Further research is needed on the relationship between the use of hypnotics and sedatives and workers' health, and on the role that work-related stress factors play in this association.

Background Individuals with reading disability or individuals with autism spectrum disorder (ASD) are characterized, respectively, by their difficulties in reading or social communication, but both groups often have impaired phonological working memory (PWM). It is not known whether the impaired PWM reflects distinct or shared neuroanatomical abnormalities in these two diagnostic groups. Methods White-matter structural connectivity via diffusion weighted imaging was examined in sixty-four children, ages 5-17 years, with reading disability, ASD, or typical development (TD), who were matched in age, gender, intelligence, and diffusion data quality. Results Children with reading disability and children with ASD exhibited reduced PWM compared to children with TD. The two diagnostic groups showed altered white-matter microstructure in the temporo-parietal portion of the left arcuate fasciculus (AF) and in the temporo-occipital portion of the right inferior longitudinal fasciculus (ILF), as indexed by reduced fractional anisotropy and increased radial diffusivity. Moreover, the structural integrity of the right ILF was positively correlated with PWM ability in the two diagnostic groups, but not in the TD group. Conclusions These findings suggest that impaired PWM is transdiagnostically associated with shared neuroanatomical abnormalities in ASD and reading disability. Microstructural characteristics in left AF and right ILF may play important roles in the development of PWM. The right ILF may support a compensatory mechanism for children with impaired PWM.

Longitudinal studies of neurodevelopmental disorders that are diagnosed at or before birth and are associated with specific learning difficulties at school-age provide one method for investigating developmental precursors of later-emerging academic disabilities. Spina bifida myelomeningocele (SBM) is a neurodevelopmental disorder associated with particular problems in mathematics, in contrast to well-developed word reading. Children with SBM (n=30) and typically developing children (n=35) were used to determine whether cognitive abilities measured at 36 and 60 months of age mediated the effect of group on mathematical and reading achievement outcomes at 8.5 and 9.5 years of age. A series of multiple mediator models showed that: visual-spatial working memory at 36 months and phonological awareness at 60 months partially mediated the effect of group on math calculations, phonological awareness partially mediated the effect of group on small addition and subtraction problems on a test of math fluency, and visual-spatial working memory mediated the effect of group on a test of math problem solving. Groups did not differ on word reading, and phonological awareness was the only mediator for reading fluency and reading comprehension. The findings are discussed with reference to theories of mathematical development and disability and with respect to both common and differing cognitive correlates of math and reading.

Objective: To evaluate the mid-term clinical efficacy of plate and intramedullary nail for humeral shaft fracture. Methods: In this retrospective study a total of 122 patients with humeral shaft fracture were divided into 2 groups according to surgery type from May 2010 to July 2012. There were 63 patients in plate group and 59 patients in intramedullary nail group. The factors related to the operation for each group were compared respectively. The clinical outcome was evaluated by the Neer scores, Myao scores and EuroQol 5 dimensions scores (EQ-5D). All the patients were followed up periodically in the next 3 years. Results: There were no significant differences between the two groups on hospital stay and time of returning to work ( P >0.05). While the operation time, amount of intraoperative blood loss and complication rate were less in intramedullary nail group. The mean follow-up duration was (41.2±4.2) months in plate group and (42.1±4.7) months in intramedullary nail group respectively. At the last follow-up the postoperative Neer scores, Myao scores and EQ-5D scores showed no significant differences between the 2 groups[Neer: (93.8±6.1) vs(92.1±4.2); Myao: (94.9±2.9) vs(96.2±1.5), P >0.05]. There were no cases complicated with nonunion, delayed union, infection and deformity during the follow-up period. Conclusions: The mid-term outcome of open reduction and internal fixation with plate and close reduction with intramedullary nail for humeral shaft fracture is satisfactory. Although both surgeries are safe and effective, they also have some defaults. The doctors should choose the right surgery carefully according to the actual situation of the patients.

The purpose of this study was to examine the effects of a violence coping program (VCP) based on Polk's middle-range theory of resilience on nursing competency, resilience, burnout, and the ability to cope with violence in nurses working in emergency rooms. A quasi-experimental study, with a nonequivalent control group and a pretest-posttest design, was conducted. Participants were 36 nurses who worked in emergency rooms and had experienced violence; 18 nurses from D hospital and 18 nurses from C hospital were assigned to the experimental and control groups, respectively. The experimental group received the VCP twice per week for 8 weeks. Levels of resilience, F=59.41, p<.001, active coping behavior, χ²=33.09, p<.001, and nursing competency, F=59.41 p<.001, increased significantly and levels of passive coping behavior, χ²=22.92, p<.001, and burnout, F=52.74, p<.001, decreased significantly in the experimental group. The results suggest that the VCP could be an effective strategy for reducing burnout and improving resilience, active coping behavior, and nursing competency. Therefore, it would be a useful intervention for improving the quality of nursing care provided in emergency rooms. © 2017 Korean Society of Nursing Science

Artifact removal in the context of group ICA: a comparison of single-subject and group approaches

Independent component analysis (ICA) has been widely applied to identify intrinsic brain networks from fMRI data. Group ICA computes group-level components from all data and subsequently estimates individual-level components to recapture inter-subject variability. However, the best approach to handle artifacts, which may vary widely among subjects, is not yet clear. In this work, we study and compare two ICA approaches for artifacts removal. One approach, recommended in recent work by the Human Connectome Project, first performs ICA on individual subject data to remove artifacts, and then applies a group ICA on the cleaned data from all subjects. We refer to this approach as Individual ICA based artifacts Removal Plus Group ICA (IRPG). A second proposed approach, called Group Information Guided ICA (GIG-ICA), performs ICA on group data, then removes the group-level artifact components, and finally performs subject-specific ICAs using the group-level non-artifact components as spatial references. We used simulations to evaluate the two approaches with respect to the effects of data quality, data quantity, variable number of sources among subjects, and spatially unique artifacts. Resting-state test-retest datasets were also employed to investigate the reliability of functional networks. Results from simulations demonstrate GIG-ICA has greater performance compared to IRPG, even in the case when single-subject artifacts removal is perfect and when individual subjects have spatially unique artifacts. Experiments using test-retest data suggest that GIG-ICA provides more reliable functional networks. Based on high estimation accuracy, ease of implementation, and high reliability of functional networks, we find GIG-ICA to be a promising approach. PMID:26859308

Our objective was to evaluate the utility of the national database (NDB) based on health insurance claims data for antimicrobial use (AMU) surveillance in medical institutions in Japan. The population-weighted total AMU expressed as defined daily doses (DDDs) per 1000 inhabitants per day (DID) was measured by the NDB. The data were compared with our previous study measured by the sales data. Trend analysis of DID from 2011 to 2013 and subgroup analysis stratified by antimicrobial category and age group were performed. There was a significant linear correlation between the AMUs measured by the sales data and the NDB. Total oral and parenteral AMUs (expressed in DID) were 1.04-fold from 12.654 in 2011 to 13.202 in 2013 and 1.13-fold from 0.734 to 0.829, respectively. Percentage of oral form among total AMU was high with more than 94% during the study period. AMU in the children group (0-14 years) decreased from 2011 to 2013 regardless of dosage form, although the working age group (15-64 years) and elderly group (65 and above years) increased. Oral AMU in the working age group was approximately two-thirds of those in the other age groups. In contrast, parenteral AMU in the elderly group was extremely high compared to the other age groups. The trend of AMU stratified by antimicrobial category and age group were successfully measured using the NDB, which can be a tool to monitor outcome indices for the national action plan on antimicrobial resistance.

Working memory processing in ecstasy (3,4-methylenedioxymethamphetamine) users is associated with neural alterations as measured by functional magnetic resonance imaging. Here, we examined whether cortical activation patterns change after prolonged periods of continued use or abstinence from ecstasy and amphetamine. We used an n-back task and functional magnetic resonance imaging in 17 ecstasy users at baseline (t(1)) and after 18 months (t(2)). Based on the reported drug use at t(2) we separated subjects with continued ecstasy and amphetamine use from subjects reporting abstinence during the follow-up period (n = 9 and n = 8, respectively). At baseline both groups had similar task performance and similar cortical activation patterns. Task performance remained unchanged in both groups. Furthermore, there were no detectable functional magnetic resonance imaging signal changes from t(1) to t(2) in the follow-up abstinent group. However, the continuing users showed a dose-dependent increased parietal activation for the 2-back task after the follow-up period. Our data suggest that ecstasy use, particularly in high doses, is associated with greater parietal activation during working memory performance. An altered activation pattern might appear before changes in cognitive performance become apparent and, hence, may reflect an early stage of neuronal injury from the neurotoxic drug ecstasy.

It is generally considered that working memory (WM) capacity is limited and that WM capacity affects cognitive processes. Distractor filtering efficiency has been suggested to be an important factor in determining the visual working memory (VWM) capacity of individuals. In the present study, we investigated whether training in visual filtering efficiency (FE) could improve VWM capacity, as measured by performance on the change detection task (CDT) and changes of contralateral delay activity (CDA) (contralateral delay activity) of different conditions, and evaluated the transfer effect of visual FE training on verbal WM and fluid intelligence, as indexed by performance on the verbal WM span task and Raven's Standard Progressive Matrices (RSPM) test, respectively. Participants were divided into high- and low-capacity groups based on their performance in a CDT designed to test VWM capacity, and then the low-capacity individuals received 20 days of FE training. The training significantly improved the group's performance in the CDT, and their CDA models of different conditions became more similar with high capacity group, and the effect generalized to improve verbal WM span. These gains were maintained at a 3-month follow-up test. Participants' RSPM scores were not changed by the training. These findings support the notion that WM capacity is determined, at least in part, by distractor FE and can be enhanced through training.

Burnout syndrome is an emerging disease among health professionals. The aim of this study is to determine the prevalence of occupational burnout among Primary Care staff, as well as to determine the differences in prevalence between family doctors, paediatricians, nurses, administrative-officers, and social-workers, and to evaluate the different related factors. A cross-sectional, descriptive study was conducted on 178 professionals from 5 different occupational groups in 54 Primary Care centres in Navarre from September to December 2010. An anonymous, self-administered questionnaire that included: the Maslach Burnout Inventory and a questionnaire on socio-demographic and work-related factors. Burnout was detected in 39.3% of staff. Those with higher levels are administrative-officers and family doctors, with an OR compared to nurses of 4.58 and 5.37, respectively in the dimension of emotional exhaustion, 4.98 and 2.87 in depersonalization, and 8.37 for administrative-officers in personal accomplishment. An association was found between burnout and the following factors: to be a male (for the dimensions of emotional exhaustion and depersonalization, 25.5 and 31.9%, respectively), to be employed in an urban area (for emotional exhaustion and depersonalization, 20 and 27.8%, respectively), use of psychiatric medication (for emotional exhaustion, 30%), size of patient-quota (for depersonalization, with an average of 1,565 patients), and welfare pressure (for emotional exhaustion and depersonalization, averages of 170.35 and 153.54 patients/week, respectively). About one-third of Primary Care professionals have a high level of burnout, which is mainly associated with the working area, the size of the quota, and professional group, with higher prevalence in administrative-officers and family doctors.

This study concerns 273 Spanish adolescents, aged between 14 and 17, 125 boys and 148 girls. The measured variables were political tolerance, liking for several groups, political experience, cognitive moral reasoning, support for democratic norms, support for violent groups, identification with a group of friends, identification with a religious group, and identification with a soccer team. The objectives of this work were (a) to establish groups of adolescents based on the relationship between their willingness to extend rights to several groups and their liking of these groups, (b) to know the personality characteristics of tolerant and intolerant adolescents, and (c) to set up correlations between age and total tolerance, total liking, and the variables correlated with tolerance. The main findings are that older and younger adolescents belong to different groups, with respect to tolerance, and something similar can be said about boys and girls. Intolerant adolescents perceive themselves as anxious, insecure, solitary, and obstinate. Significant positive correlations between age and political experience, rated support for democratic norms and ratings for identification with a group of friends were found. On the contrary, there were significant negative correlations between age and rated support for violent groups, identification with a religious group, and identification with a soccer team.

We examined effects of an angiotensin-II receptor blockers, candesartan cilexetil, in rats with dilated cardiomyopathy after autoimmune myocarditis. Candesartan cilexetil showed angiotensin-II blocking action in a dose-dependent manner in rats with dilated cardiomyopathy. Twenty-eight days after immunization, surviving Lewis rats were divided into four groups and given candesartan cilexetil at 0.05 mg/kg, 0.5 mg/kg or 5 mg/kg per day (Group-C0.05, n = 15, Group-C0.5, n = 15 and Group-C5, n = 15, respectively) or vehicle alone (Group-V, n = 15). After oral administration for 1 month, the left ventricular end-diastolic pressure and heart weight/body weight ratio were lower in Group-C0.05 (13.3+/-1.1 mmHg and 3.7+/-0.2 g/kg, respectively), in Group-C0.5 (8.0+/-0.9 mmHg and 3.3+/-0.1 g/kg, respectively) and in Group-C5 (5.5+/-1 mmHg and 3.1+/-0.1 g/kg, respectively) than in Group-V (13.5+/-1.0 mmHg and 3.8+/-0.2 g/kg, respectively). The area of myocardial fibrosis was also lower in Group-C0.05 (25+/-3%), in Group-C0.5 (20+/-3%), and in Group-C5 (12+/-1%) than in Group-V (32+/-4%). Furthermore, expressions of transforming growth factor-beta1 and collagen-III mRNA were suppressed in Group-C0.05 (349+/-23% and 395+/-22%, respectively), Group-C0.5 (292+/-81% and 364+/-42%, respectively) and in Group-C5 (204+/-63% and 259+/-33%, respectively) compared with those in Group-V (367+/-26% and 437+/-18%, respectively). These results suggest that candesartan cilexetil can improve the function of inefficient heart.

We conducted neuropsychological tests of patients with higher brain dysfunction to examine the characteristics of barriers to employment. We tested 92 patients with higher brain dysfunction (average age of 36.3 +/- 13.8 years old, ranging between 16 and 63 years old, with an average post-injury period of 35.6 +/- 67.8 months) who were hospitalized at the university hospital between February 2002 and June 2007 for further neuropsychological evaluation, conducting the Wechsler Adult Intelligence Scale-Revised (WAIS-R), Wechsler Memory Scale-Revised (WMS-R), the Rivermead Behavioral Memory Test (RBMT), Frontal Assessment Battery (FAB) and Behavioral Assessment of Dysexecutive Syndrome (BADS). The outcomes after discharge were classified between competitive employment, sheltered employment and non-employment, and the three groups were compared using one-way analysis of variance and the Scheffe test. The WAIS-R subtests were mutually compared based on the standard values of significant differences described in the WAIS-R manual. Verbal performance and full scale Intelligence Quotient (IQ) of WAIS-R were 87.7 +/- 15.6 (mean +/- standard deviation), 78.5 +/- 18.1 and 81.0 +/- 17.2, respectively, and verbal memory, visual memory, general memory, attention/concentration and delayed recall were 74.6 +/- 20.0, 76.6 +/- 21.4, 72.0 +/- 20.4, 89.0 +/- 16.5 and 65.2 +/- 20.8, respectively. The competitive employment group showed significantly higher scores in performance IQ and full IQ on the WAIS-R and verbal memory, visual memory, general memory and delayed recall on the WMS-R and RBMT than the non-employment group. The sheltered employment group showed a significantly higher score in delayed recall than the non-employment group. No difference was observed in the FAB or BADS between the three groups. In the subtests of the WAIS-R, the score for Digit Symbol-Coding was significantly lower than almost all the other subtests. For patients with higher brain dysfunction, IQ (full scale IQ > 53.2) and memory (general memory > 74.1) are important indicators in returning to work under the conditions of competitive employment.

Ertl and Non-Ertl amputees exhibit functional biomechanical differences during the sit-to-stand task.

People with transtibial amputation stand ~50times/day. There are two general approaches to transtibial amputation: 1) distal tibia and fibula union using a "bone-bridge" (Ertl), 2) non-union of the tibia and fibula (Non-Ertl). The Ertl technique may improve functional outcomes by increasing the end-bearing ability of the residual limb. We hypothesized individuals with an Ertl would perform a five-time sit-to-stand task faster through greater involvement/end-bearing of the affected limb. Ertl (n=11) and Non-Ertl (n=7) participants sat on a chair with each foot on separate force plates and performed the five-time sit-to-stand task. A symmetry index (intact vs affected limbs) was calculated using peak ground reaction forces. The Ertl group performed the task significantly faster (9.33s (2.66) vs 13.27 (2.83)s). Symmetry index (23.33 (23.83)% Ertl, 36.53 (13.51)% Non-Ertl) indicated the intact limb for both groups produced more force than the affected limb. Ertl affected limb peak ground reaction forces were significantly larger than the Non-Ertl affected limb. Peak knee power and net work of the affected limb were smaller than their respective intact limb for both groups. The Ertl intact limb produced significantly greater peak knee power and net work than the Non-Ertl intact knee. Although loading asymmetries existed between the intact and affected limb of both groups, the Ertl group performed the task ~30% faster. This was driven by greater power and work production of the Ertl intact limb knee. Our results suggest that functional differences exist between the procedures. Copyright © 2017 Elsevier Ltd.

This paper examines how positive psychology principles can be incorporated into clinical training and practice to work with lesbian, gay, bisexual and transgender (LGBT) clients. LGBT psychology literature has all too often relied on heterosexual and cisgender reference groups as the norm with respect to psychological health, primarily framing the experiences of LGBT individuals through the lens of psychopathology. As a result, strengths that could be ascribed to the LGBT experience have been overlooked within training and practice. While positive psychology is actively being incorporated into clinical and counseling psychology curricula, broadening the paradigm to include LGBT individuals has generally not been included in the discussion. Specific recommendations for training psychologists to incorporate and foster positive social institutions, positive subjective experiences and character strengths when working with LGBT clients and celebrating their unique experiences are provided.

The health gains and cost savings from tobacco tax increase peak many decades into the future. Policy-makers may take a shorter-term perspective and be particularly interested in the health of working-age adults (given their role in economic productivity). Therefore, we estimated the impact of tobacco taxes in this population within a 10-year horizon. As per previous modelling work, we used a multistate life table model with 16 tobacco-related diseases in parallel, parameterised with rich national data by sex, age and ethnicity. The intervention modelled was 10% annual increases in tobacco tax from 2011 to 2020 in the New Zealand population (n=4.4 million in 2011). The perspective was that of the health system, and the discount rate used was 3%. For this 10-year time horizon, the total health gain from the tobacco tax in discounted quality-adjusted life years (QALYs) in the 20-65 year age group (age at QALY accrual) was 180 QALYs or 1.6% of the lifetime QALYs gained in this age group (11 300 QALYs). Nevertheless, for this short time horizon: (1) cost savings in this group amounted to NZ$10.6 million (equivalent to US$7.1 million; 95% uncertainty interval: NZ$6.0 million to NZ$17.7 million); and (2) around two-thirds of the QALY gains for all ages occurred in the 20-65 year age group. Focusing on just the preretirement and postretirement ages, the QALY gains in each of the 60-64 and 65-69 year olds were 11.5% and 10.6%, respectively, of the 268 total QALYs gained for all age groups in 2011-2020. The majority of the health benefit over a 10-year horizon from increasing tobacco taxes is accrued in the working-age population (20-65 years). There remains a need for more work on the associated productivity benefits of such health gains. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Despite the global expansion of supply chains and changes to the production process, few studies since the mid-1990 s and 2000s have examined reproductive risks of the microelectronics industry; we examined the reproductive risks among female microelectronics workers in South Korea. Based on claim data from the National Health Insurance (2008-2012), we estimated age-specific rates of spontaneous abortion (SAB) and menstrual aberration (MA) among women aged 20 to 39 years. We compared data between microelectronics workers and three different control groups: economically inactive women, the working population as a whole, and workers employed in the bank industry. For an effect measure, age-stratified relative risks (RRs) were estimated. Female workers in the microelectronics industry showed significantly higher risk for SAB and MA compared to control groups. The RRs for SAB with reference to economically inactive women, working population, and bank workers in their twenties were 1.57, 1.40, and 1.37, respectively, and the RRs for MA among females in their twenties were 1.54, 1.38, and 1.48, respectively. For women in their thirties, RRs for SAB were 1.58, 1.67, and 1.13, and those for MA were 1.25, 1.35, and 1.23 compared to the three control populations, respectively. All RRs were statistically significant at a level of 0.05, except for the SAB case comparison with bank workers in their thirties. Despite technical innovations and health and safety measures, female workers in microelectronics industry in South Korea have high rates of SAB and MA, suggesting continued exposure to reproductive hazards. Further etiologic studies based on primary data collection and careful surveillance are required to confirm these results.

Little is known about the awareness of public health professionals regarding racial and ethnic disparities in health in the United States of America (USA). Our study objective was to assess the awareness and perceptions of a group of public health workers in Texas regarding racial health disparities and their chief contributing causes. We surveyed public health professionals working on a statewide grant in Texas, who were participants at health disparities' training workshops. Multivariable logistic regression was employed in examining the association between the participants' characteristics and their perceptions of the social determinants of health as principal causes of health disparities. There were 106 respondents, of whom 38 and 35 % worked in health departments and non-profit organizations, respectively. The racial/ethnic groups with the highest incidence of HIV/AIDS and hypertension were correctly identified by 63 and 50 % of respondents, respectively, but only 17, and 32 % were knowledgeable regarding diabetes and cancer, respectively. Seventy-one percent of respondents perceived that health disparities are driven by the major axes of the social determinants of health. Exposure to information about racial/ethnic health disparities within the prior year was associated with a higher odds of perceiving that social determinants of health were causes of health disparities (OR 9.62; 95 % CI 2.77, 33.41). Among public health workers, recent exposure to information regarding health disparities may be associated with their perceptions of health disparities. Further research is needed to investigate the impact of such exposure on their long-term perception of disparities, as well as the equity of services and programs they administer.

It is recommended that endotracheal cuff (ETTc) pressure be between 20 and 30 cm H 2 O. In this present study, we intend to observe average cuff pressure values in our clinic and the change in these values after the training seminar. The cuff pressure values of 200 patients intubated following general anesthesia induction in the operating theatre were measured following intubation. One hundred patients whose values were measured before the training seminar held for all physician assistants, and 100 patients whose values were measured after the training seminar were regarded as Group 1 and Group 2, respectively. Cuff pressures of both groups were recorded, and the difference between them was shown. Moreover, cuff pressure values were explored according to the working period of the physician assistants. There was no significant difference between the groups in terms of age, gender and tube diameters. Statistically significant difference was found between cuff pressure values before and after the training (p < 0.001). Average pressure measure for Group I was 54 cm H 2 O, while average pressure in Group II declined to 33 cm H 2 O. It was observed that as the working period and experience of physician assistants increased, cuff pressure values decreased, however no statistically significant different was found (p < 0.375). We believe that clinical experience does not have significant effects on cuff pressure and that training seminars held at intervals would prevent high cuff pressure values and potential complications.

The purpose of this paper is to explore the relationship between evolutionary theory and ethology in the work of Konrad Lorenz, Niko Tinbergen and V.C. Wynne-Edwards, the farmer, hunter, and census taker of the title respectively. I am especially interested in the idea of the ethologists Lorenz and Tinbergen that animal behavior and human behavior were equally appropriated subjects of biological analysis. Their approach is contrasted with Wynne-Edwards's group selective account of the evolution of social behavior. Finally, I argue that Wynne-Edwards's dogged commitment to group selection theory helped create the theoretical space within which subsequent researchers could develop more careful analyses.

The aim of this study was to examine whether employees in pre-schools that implemented a participatory organizational-level intervention focusing on the core task at work had a lower incidence of short-term sickness absence compared to employees in the control group. The cluster randomized controlled trial (RCT) comprised 78 pre-schools that were allocated to the intervention (44 pre-schools with 1760 employees) or control (34 pre-schools with 1279 employees) group. The intervention lasted 25 months and followed a stepwise and structured approach, consisting of seminars, workshops, and workplace-directed intervention activities focusing on the core task at work. Using Poisson regression, we tested differences in incidence rates in short-term sickness absence between the intervention and control groups during a 29-months follow-up. Estimated short-term sickness absence days per person-year during follow-up were 8.68 and 9.17 in the intervention and control groups, respectively. The rate ratio (RR) for comparing incident sickness absence in the intervention to control groups during follow-up was 0.93 [95% confidence interval (95% CI) 0.86-1.00] in the crude analysis and 0.89 (95% CI 0.83-0.96) when adjusting for age, sex, job group, type and size of workplace, and workplace average level of previous short-term sickness absence. A supplementary analysis showed that the intervention also was associated with a reduced risk of long-term sickness absence with a crude RR of 0.83 (95% CI 0.69-0.99) and an adjusted RR of 0.84 (95% CI 0.69-1.01). Pre-school employees participating in an organizational-level occupational health intervention focusing on the core task at work had a lower incidence of short-term sickness absence during a 29-month follow-up compared with control group employees.

The aim of this study was to examine the relationship between noise exposure and risk of occupational injury. Korean National Health and Nutrition Examination Survey was used for the current study. Self-report questionnaires were used to investigate occupational injury and exposure to noise, chemicals, and machines and equipments. In separate analyses for occupation and occupational hazard, the proportion of occupational injuries increased according to severity of noise exposure (all P < 0.05). Compared to the non-exposure group, the respective odds ratio (95% confidence intervals) for occupational injury was 1.39 (1.07-1.80) and 1.67 (1.13-2.46) in the mild and severe noise exposure groups, after controlling for age, gender, sleep hours, work schedule (shift work), and exposure status to hazardous chemicals and hazardous machines and equipments. The current study highlights the association between noise exposure and risk of occupational injury. Furthermore, risk of occupational injury increased according to severity of noise exposure.

The financial difficulties encountered by Martinique hospitals has led to restructuring of the territory's medical project with the merger of three healthcare facilities. These new constraints impacting the work environment with organizational consequences in services. A management experiment was attempted in a geriatric day care hospital based on the use of health promotion concepts. After an overview of the unit's activity based on the perceptions of staff, patients and private physicians, a one-day research-action structural seminar was organized. Group dynamics, unit functioning, shared values, success factors, and improvement strategies were discussed. This seminar resulted in the development of a business model based on five values (respect, professionalism, cohesion, empathy, communication). Three operational working groups were established to implement the conclusions of the seminar in the unit. This experiment focused on an alternative approach to the management of small health care services by the use of health promotion.

Development of Number Line Representations in Children With Mathematical Learning Disability

Geary, David C.; Hoard, Mary K.; Nugent, Lara; Byrd-Craven, Jennifer

2015-01-01

Children with a mathematical learning disability (MLD, n = 19) and low achieving (LA, n = 43) children were identified using mathematics achievement scores below the 11th percentile and between the 11th and 25th percentiles, respectively. A control group of typically achieving (TA, n = 50) children was also identified. Number line and speed of processing tasks were administered in 1st and 2nd grade and a working memory battery in 1st grade. In both grades, the MLD children were less accurate in their number line placements and more reliant on a natural number-magnitude representational system to make these placements than were TA children. The TA children were more reliant on the school-taught linear system in both grades. The performance of the LA children was similar to that of the MLD children in first grade and to the TA children in second. The central executive component of working memory contributed to across-grade improvements in number line performance and to group differences in this performance. PMID:18473200

The resident curriculum of the American Board of Orthopaedic Surgery emphasizes radiation safety. Gendelberg showed that, immediately after a program on fluoroscopic safety, residents used less radiation when using the mini C-arm to reduce pediatric fractures. The current study evaluated whether this effect lasted. Residents underwent a new annual 3-hour session on mini C-arm use and radiation. Group A included 53 reductions performed before training. Group B included 45 reductions performed immediately after training. Group C included 46 reductions performed 11 months later. For distal radius fractures, exposure time and amount were 38.1 seconds and 83.1 mR, respectively, for group A; 26.7 seconds and 32.6 mR, respectively, for group B; and 24.1 seconds and 40.0 mR, respectively, for group C. When radiation time and amount were compared between group B and group C, P values were .525 and .293, respectively. When group C and group A were compared, P values were <.05 and <.01, respectively. For both bone forearm fractures, exposure time and amount were 41.2 seconds and 90.9 mR, respectively, for group A; 28.9 seconds and 30.4 mR, respectively, for group B; and 31.2 seconds and 43.6 mR, respectively, for group C. When radiation time and amount were compared between group B and group C, P values were .704 and .117, respectively. When group C and group A were compared, P values were .183 and .004, respectively. No significant difference in radiation exposure was noted immediately after training vs 11 months later. A sustained decrease in radiation exposure occurred after an educational program on safe mini C-arm use. [Orthopedics. 2017; 40(5):e788-e792.]. Copyright 2017, SLACK Incorporated.

Bjerkan, Anne Mette

2011-01-01

The effect of work-related variables on self reported health complaints were examined among Norwegian onshore and offshore oil workers. Differences in work and health perceptions were also examined as part of the paper. Employees working onshore and offshore in the maintenance and modification division of a large contractor company took part in the study (N=414, response rate 47.1%). The design of the study was a cross-sectional survey. A questionnaire was distributed to onshore personnel while at work - in cooperation with the personnel safety representative - and sent to the home addresses of the offshore personnel. Offshore workers perceived significantly more hazards associated with the work and experienced less control over the work pace compared to onshore workers. Onshore workers experienced significantly more pressure at work and their work tasks as more repetitive. Differences in health perceptions were identified in terms of job type in the onshore and offshore groups respectively. Different work-related factors influenced the self-reported health complaints among onshore and offshore workers. Workers in different work environments and in different job types encounter different type of threats to employee health, indicating that job type must be taken into account when studying the relationship between work-related factors and employee health.
