Rural sex work in Cambodia: work characteristics, risk behaviours, HIV, and syphilis.

OBJECTIVE: To identify prevalence and risks factors for syphilis and HIV among rural female sex workers (FSWs) in Cambodia and to describe differences between rural and urban FSWs. METHODS: Interviews and sera were collected from 114 FSWs and tested for HIV using the Serodia-HIV test and positives confirmed with the enzyme linked immunosorbent assay. Syphilis was tested for with the rapid plasma reagin with passive particle agglutination test for detection of antibody of Treponema pallidum. Study data were merged with data from a study of urban FSWs from Phnom Penh that applied similar questionnaires and sampling design to compare STI prevalence and behaviours. RESULTS: 42% of rural FSWs were HIV positive; 22% had past or current syphilis. In multivariate models HIV was significantly associated with age > or = 25 (OR = 6.1 95% CI: 1.0 to 36.6), a non-commercial partner in the past year (OR= 0.33, 95% CI: 0.11 to 0.93), and prevalence of past or current syphilis (OR = 2.9, 95% CI: 1.0 to 8.8). There was significantly higher active syphilis (14% v 4%), older mean age (25 v 21), fewer daily clients (2 v 5), lower monthly income (61 US dollars v 174 US dollars), and longer duration of sex work (2.3 years v 1.4 years) among rural than among urban FSWs. CONCLUSIONS: These findings reveal a high burden of HIV and syphilis among FSWs in rural Cambodia. As FSWs age and become infected with STI/HIV they may move out of cities into less competitive but less savvy markets; their high mobility may contribute to the expansion of the HIV epidemic into rural Cambodia and lower risk populations.

"Whistle while you work": a historical account of some associations among music, work, and health.

Music has long been a uniting force among workers. Music can improve team spirit and provide an enjoyable diversion, but it is most useful in expressing the true feelings of a sometimes desperate community. Over time, a variety of musical media have emerged to match the prevailing conditions at work: the folk songs of 19th-century handloom weavers, the songs of industrial Britain's trade union members, the workers' radio programs of the 1940s. Associations have arisen to encourage and coordinate musical activities among workers, and public awareness of the hazards of some occupations has been promoted through music.

[A method for assessment and evaluation of physical stress: work load at work sites in traffic].

The method outlined here allows to evaluate the physical load of an overall activity from the assessment of simple activities making up the overall activity. These simple activities can be measured by means of various procedures. They are evaluated in units of physical load whereas the index of the overall activity is determined using the weighted arithmetic means. This method was used to establish a catalogue of physical load in working places in the field of transport.

[Grounds of the duration of work shift for female vegetable growers working in the field in the summer].

Analysis of changes in heat state of female vegetable-growers within the shift helped to determine correlation between microclimate parameters (including general indicator of extrinsic heat load--WBGT index) and temperature state in the females adjusted and non-adjusted to heat. Depending on various relationships between the microclimate parameters inducing variable overheating, duration of the working shift is set for stably optimal heat state.

Case management at work for SSA disability beneficiaries: process results of the Project NetWork return-to-work demonstration.

This article presents the results of the process analysis of the evaluation of the Project NetWork demonstration, a Federal demonstration undertaken by the Social Security Administration (SSA) in 1991 to test alternative methods of providing rehabilitation and employment services to SSA's Disability Insurance beneficiaries and Supplemental Security Income disabled and blind applicants and recipients. The major findings are: (1) from an operational standpoint, it is feasible to expand access to vocational rehabilitation (VR) services to a broad spectrum of SSA beneficiaries, and (2) roughly similar results are achieved, in terms of client intake and provision of services, when case management services are provided by SSA staff, contracted out to State VR agencies, or contracted with private VR providers. Later evaluation reports will trace demonstration impacts on earnings and disability benefits and report the overall benefits and costs of return-to-work services for this population.

How does work work for people with bipolar affective disorder?

Despite modern treatments, bipolar disorder remains a chronic, relapsing disorder that leads to long-term psychosocial disability. A review of the literature suggests that while employment rates amongst individuals with bipolar disorder may improve over time, and are relatively better compared to some other chronic mental disorders, employment prospects do not match the high scholastic achievements seen amongst this group of people before the onset of their illness. For those with bipolar disorder, clinical recovery does not necessarily mean functional recovery, and the usual early age of onset may further reduce an individual's preparedness for employment. Two brief vignettes are used to discuss how occupational therapists can help their clients maintain their sense of hope in vocational recovery, gain better self-awareness and work with clients at various stages of recovery rather than waiting for full functional recovery. Further research is required to help identify specific factors that contribute to the success of employment integration amongst people with bipolar disorder.

The Working Well Trial: baseline dietary and smoking behaviors of employees and related worksite characteristics. The Working Well Research Group.

BACKGROUND: The Working Well Trial, the largest randomized worksite health promotion trial to date, tests the effects of cancer prevention and control interventions on dietary and smoking behaviors of employees and the worksite environment. The trial is a 5-year cooperative agreement conducted in 57 matched pairs of worksites in 16 states by four study centers, a coordinating center, and the National Cancer Institute. The dual aims of this paper are to: (a) present a baseline description of the dietary and smoking habits of 20,801 employees, who are predominantly blue-collar workers; and (b) describe the social and physical environments of their worksites that may facilitate or hinder health behavior changes. METHODS: The self-administered baseline survey of individuals consisted of a core set of questions common across all study centers on diet and smoking. The organizational survey consisted of eight instruments administered via interviews with key informants in each worksite. Continuous variable were analyzed by a mixed linear model and binary data were analyzed by the Generalized Estimating Equation. RESULTS: The population represented is largely male (67.5%) and blue collar (53.5%). Mean levels of fat and fiber intakes were close to the national averages (36.6% of calories as fat and 13.1 g of fiber). Smoking prevalence (25.2%) was slightly lower than the national average. The worksites had a high level of health promotion activities (42% had nutrition programs, 53% had smoking control programs), but lacked environmental support for dietary behavior change and perceived support for smoking cessation. CONCLUSIONS: These findings replicate and extend previous research results to a large sample of diverse, largely blue-collar worksites. In addition the baseline results lay a foundation for the development of new insights into the relationship between individual and organizational level variables that may interact to influence behavioral and cultural norms.

Knee moment at work: validation of a questionnaire based on knee moment in working life.

Classifications of occupations, such as those of the International Labor Organization, have previously been constructed with respect to the physical strain and joint moment to be expected in conjunction in a profession. To detect which occupational activities specifically induce high knee moments, we designed a questionnaire to analyze walking, knee bending, climbing of stairs and ladders, and jumping during three consecutive 15-year exposure periods in the professional lives of 920 consecutive residents [329 men with a mean age of 72 (range 47-96) and 561 women with a mean age of 77 (range 47-96)] drawn from the population records of the City of Malmö. The answers, classified into three categories with respect to knee joint moment, were compared with a classification of the occupations of all probands according to the same principles by three independent specialists in industrial hygiene. The two classifications showed a high degree of agreement, with Cramer's V ranging from 0.49 to 0.6, suggesting a co-variance with a common variable, i.e. the true work-related knee moment.

[A standardized documentation structure for data documentation in echocardiography. Work Team on Standards and LV Function of the Work Group on Cardiovascular Ultrasound of the German Society of Cardiology, Heart and Circulation Research].

Presently, there are no well-defined standards for documentation of echocardiographic studies. Nevertheless, standards are essential to provide comparability of data and to realize electronic communication, both essential for quality management in echocardiography. Therefore, the working group "Standards and LV function" of the German Society of Cardiology developed a consensus for documentation of echocardiographic studies. In the present paper this consensus is presented and illustrated by typical clinical examples. Additionally, a prototype of a user-oriented software based on this data set is presented. The complete data set for transesophageal and transthoracic echocardiography and the software prototype can be downloaded at http:@echo.ma.uni-heidelberg.de.

Return-to-work outcomes following work disability: stakeholder motivations, interests and concerns.

INTRODUCTION: Satisfaction with return-to-work (RTW) outcomes is dependent on many factors, including a clear exposition of what people define as a "good outcome" and the information they use to determine if such an outcome has been achieved. This paper defines the key stakeholders involved in the RTW process and discusses the need to understand their motivations, interests, and concerns. METHODS: A review of the literature and discussions with RTW researchers conducted by a multidisciplinary group of academic researchers. RESULTS: Our analysis suggests that RTW stakeholders can share the goal of a successful RTW; however, this consensus has to be viewed in light of other, sometimes competing, goals and the environments in which stakeholders operate. CONCLUSIONS: It is suggested that more clearly articulating and operationalizing stakeholders' perspectives will allow researchers to advance the understanding of RTW interventions and outcomes.

Tuberculosis in London: a review, and an account of the work of the London Consultants in Communicable Disease Control Group Working Party.

Tuberculosis (TB) has been recorded in London for centuries but reports have declined over the last 100 years, with a 10-fold decrease between 1948 and 1987. However, from 1987-1993 notifications of TB in London rose by 34%, compared with 15% nationally. This rise, together with concerns about undernotification and the emergence of multi-drug resistance in New York, led to establishment of a London Consultants in Communicable Disease Control Working Party on TB to review current surveillance data. Notifications to the Office of Population Censuses and Surveys from the London Boroughs declined by approximately 6.5% per year from 1982-1987. If this had continued until 1993 there would have been 3579 fewer notifications than actually received. The proportion of cases in the 15-44 age group rose markedly in males. The proportion of notifications in those aged 65 and above was higher in the Thames Regions outside London, where the total TB notifications declined by 3.5% over the same period. Recommendations were made to improve TB surveillance in London; and a city-wide surveillance function was established in 1994 to collate and monitor data on TB.

Self-initiated encoding facilitates object working memory in schizophrenia: implications for the etiology of working memory deficit.

BACKGROUND: Working memory (WM) deficit is present in a majority of patients with schizophrenia but it is unclear which components of WM are impaired. Past studies suggest that encoding may be compromised. One important determinant of encoding is the deployment of selective attention to the target stimulus. In addition, attention and encoding are modulated by motivational factors. In this study, we investigated the effects of self-initiated encoding (i.e., voluntary attention) on WM. METHODS: 19 patients with schizophrenia and 19 matched control subjects participated in visual WM and control tasks. Encoding was manipulated by asking subjects to select from two face targets and memorize 1) one of the two identical faces (Non-preference condition), 2) one that is marked (Non-choice condition), and 3) one they prefer (Preference condition). WM accuracy for both location (spatial) and identity (object) was measured. RESULTS: Overall, patients with schizophrenia were less accurate and slower than the control subjects but the deficit was greater for object WM. However, patients were more accurate in object WM when they selected a preferred face as their target during encoding (preference condition) compared with the other two conditions. This effect was not significant for spatial WM. CONCLUSIONS: These results suggest that voluntary, self-initiated attention may facilitate object encoding especially if the selection of the target involves affective choice, and that attention may play different roles in encoding 'what' versus 'where' in WM. Since encoding affects all forms of memory, these results may have a more general implication for memory.

N-methyl-D-aspartate receptor in working memory impairments in schizophrenia: event-related potential study of late stage of working memory process.

Working memory (WM) deficit in schizophrenic patients has been well established. Still, underlying biological substrate of the impairment is not clear. Among neurotransmitter hypotheses of schizophrenia, N-methyl-D-aspartate (NMDA) receptor model is mostly supported, considering that NMDA receptor antagonist can elicit both psychosis and cognitive impairment observed in schizophrenic patients. In current study, to test the neuropsychological and the electrophysiological effects of NMDA receptor in WM, event-related potentials (ERPs) of Sternberg's short-term memory scanning task (SMST) were analyzed in 10 healthy subjects under intravenous administration of a subanesthetic dose of ketamine (0.65 mg/kg/h) or placebo (normal saline). Late positive component (LPC) of ERP was hypothesized to reflect later stage of WM. Brief Psychiatric Rating Scale score was significantly increased (t=-5.75, df=9, P<.001) and correct response rate was significantly decreased (t=2.21, df=9, P=.054) after ketamine administration. Neither reaction time nor LPC latency, which reflect memory scanning time, was changed. Amplitude of LPC was significantly reduced after ketamine administration (z=-2.31, number of observations=120, P=.021). In conclusion, NMDA receptor antagonist administration elicited WM deficit both in behavioral and electrophysiological level. Electrophysiological component reflecting later stage of WM was impaired by NMDA antagonist.

Interchangeability of the Working Alliance Inventory and Working Alliance Inventory, Short Form.

Working Alliance Inventory (WAI) ratings were compared with ratings comprising the 12-item WAI, Short Form (WAI-S). Responses were collected from 54 university counseling center client-therapist pairs after the 4th therapy session as well as at a final ratings point. WAI and WAI-S scores were highly correlated and had comparable descriptive statistics, internal consistencies, and subscale intercorrelations within and across rater perspectives. Predictive validity estimates for WAI and WAI-S total scales were also very similar. Fourth-session WAI and WAI-S scores were moderately predictive of therapy improvement ratings. Results support the interchangeability of scores on the WAI and WAI-S scales.
