In vivo kinematic behavior of the radio-capitate joint during wrist flexion-extension and radio-ulnar deviation.

The capitate is often considered the "keystone" of the carpus, not simply because of its central and prominent position in the wrist, but also because of its mechanical interactions with neighboring bones. The purpose of this study was to determine in vivo three-dimensional capitate kinematics. Twenty uninjured wrists were investigated using a recently developed, non-invasive markerless bone registration (MBR) technique. Surface contours of the capitate, third metacarpal and radius were extracted from computed tomography images of seven wrist positions and the three-dimensional motions of the capitate and third metacarpal were calculated with respect to the radius in wrist flexion-extension and radio-ulnar deviation. We found that in vivo capitate motion does not simply occur about a single pivot point like a universal joint, as demonstrated by non-intersecting rotation axes for different capitate motions. The distance between flexion and ulnar deviation axes was 3.9+/-2.0 mm, and the distance between extension and ulnar deviation axes was 3.9+/-1.4 mm. Furthermore, capitate axes for males tended to be located more distally than axes for females. However, we believe that this result is related to subject size and not to gender. We also found that there is minimal relative motion between the capitate and third metacarpal during these in vivo wrist motions. These findings demonstrate the complexity of capitate kinematics, as well as the different mechanisms through which wrist flexion, extension, radial deviation and ulnar deviation occur.

Social capital and mental illness: a systematic review.

STUDY OBJECTIVE: The concept of social capital has influenced mental health policies of nations and international organisations despite its limited evidence base. This papers aims to systematically review quantitative studies examining the association between social capital and mental illness. DESIGN AND SETTING: Twenty electronic databases and the reference sections of papers were searched to identify published studies. Authors of papers were contacted for unpublished work. Anonymised papers were reviewed by the authors of this paper. Papers with a validated mental illness outcome and an exposure variable agreed as measuring social capital were included. No limitations were put on date or language of publication. MAIN RESULTS: Twenty one studies met the inclusion criteria for the review. Fourteen measured social capital at the individual level and seven at an ecological level. The former offered evidence for an inverse relation between cognitive social capital and common mental disorders. There was moderate evidence for an inverse relation between cognitive social capital and child mental illness, and combined measures of social capital and common mental disorders. The seven ecological studies were diverse in methodology, populations investigated, and mental illness outcomes, making them difficult to summarise. CONCLUSIONS: Individual and ecological social capital may measure different aspects of the social environment. Current evidence is inadequate to inform the development of specific social capital interventions to combat mental illness.

Lost in translation: a genealogy of the "social capital" concept in public health.

STUDY OBJECTIVE: To examine the genealogy of the social capital concept in public health, with attention to the epistemological concerns and academic practices that shaped the way in which this concept was translated into public health. DESIGN: A citation-network path analysis of the public health literature on social capital was used to generate a genealogy of the social capital concept in public health. The analysis identifies the intellectual sources, influential texts, and developments in the conceptualisation of social capital in public health. PARTICIPANTS: The population of 227 texts (articles, books, reports) was selected in two phases. Phase 1 texts were articles in the PubMed database with "social capital" in their title published before 2003 (n = 65). Phase 2 texts are those texts cited more than once by phase 1 articles (n = 165). MAIN RESULTS: The analysis shows how the scholarship of Robert Putnam has been absorbed into public health research, how three seminal texts appearing in 1996 and 1997 helped shape the communitarian form that the social capital concept has assumed in public health, and how both were influenced by the epistemological context of social epidemiology at the time. CONCLUSIONS: Originally viewed in public health research as an ecological level, psychosocial mechanism that might mediate the income inequality-health pathway, the dominance of the communitarian approach to social capital has given disproportionate attention to normative and associational properties of places. Network approaches to social capital were lost in this translation. Recovering them is key to a full translation and conceptualisation of social capital in public health.

Maternal social capital and child health in Vietnam.

STUDY OBJECTIVE: To explore the association between maternal social capital and child physical and mental health in Vietnam. DESIGN: Cross sectional survey. Measures of maternal structural social capital comprised group membership, citizenship, and social support. Measures of cognitive social capital comprised trust, social harmony, sense of fairness, and belonging. Child health was measured by anthropometrics and mothers' reports of acute and chronic physical health problems and child mental health. PARTICIPANTS: 2907 mothers and their 1 year old or 8 year old children from five provinces in Vietnam. MAIN RESULTS: The study found low levels of group membership and citizenship and high levels of cognitive social capital and support, and generally higher levels of social capital among the mothers of 8 year old compared with 1 year old children. All but one association was in the hypothesised direction (that is, higher levels of social capital associated with reduced risk of child health problems). There were more statistically significant relations between maternal social capital and the health of 1 year olds compared with 8 year old children, and between measures of social support and cognitive social capital and child health, than with group membership and involvement in citizenship activities. CONCLUSION: This study is the first to explore the association between multiple dimensions of social capital and a range of different child health outcomes in the developing world. These results now need to be tested using longitudinal data.

[Colon and rectal cancer mortality in Brazilian capitals, 1980-1997].

BACKGROUND: In Brazil, colorectal tumors are among the five more important sites of neoplasms, for both sexes, in terms of mortality. The etiology of colon and rectal cancer is complex and some of the factors involved in its genesis are related to diet. Brazilian geographic regions present heterogeneous alimentary profiles, that could be influencing the distribution of the mortality rates for these tumors. OBJECTIVE: To describe the patterns of mortality from cancers of the colon and the rectum in Brazilian State capitals in the period 1980-1997. MATERIAL AND METHODS: Mortality data for individuals of both sexes, residents in Brazilian State capitals (except Palmas, Tocantins) was obtained from the Ministry of Health Mortality System (SIM/MS). We considered as death from colon and rectum cancers those whose underlying cause of death was coded as 153.0 to 153.9, 154.0 and 154.1, according to ICD 9, in the period 1980-95; C18.0 to C18.9, C19 and C20,according to ICD 10, in the period 1996-97. The trends of the standardized mortality rates from colon and rectum cancer were analyzed through linear regression models. RESULTS: The highest standardized mortality rates for colorectal cancer were observed in the South and Southeastern regions and varied between 8,0 and 10,7/100000 inhabitants. Porto Alegre (11,9), São Paulo (10,8) and Rio de Janeiro (9,6) presented the greatest rates among the State capitals in the study period. In the South region, rates of mortality for Porto Alegre and Florianópolis presented an increasing trend in the study period and the same behavior was observed for São Paulo and Vitória in the Southeastern region. Brasilia and the other capitals of the Midwest, with the exception of Goiânia, showed a tendency of increment of the mortality rates. Among the capitals of the North and Northeast regions, an increasing trend of mortality was observed in Rio Branco and Fortaleza. The separate analysis of the mortality rates for tumors of the colon and for tumors of the rectum showed a similar pattern, with higher values being observed for colon neoplasia. DISCUSSION: Regional differences in the mortality rates for colon and rectum neoplasias have been discussed for different authors, who point to the contribution of cultural and alimentary habits, and differences of life style and socioeconomic status to this heterogeneity, besides other aspects related to access to health services and quality of hospital care and preventive services. These factors must be considered in the evaluation of the differences observed in Brazilian capitals. Although the State capitals situated in South and Southeastern regions presented higher rates than the others, mortality rates of Porto Alegre (9,8/100.000) and Rio de Janeiro (9,0/100.000), in period 1983- 85, were about three times lower than those observed in the United States, Canada and France, in 1985. The sex distribution pattern of the mortality rates in Brazilian capitals was not uniform, with higher rates in men. We observed a trend of increment of the mortality rates of colorectal cancer in all Brazilian regions, similar to that was observed in some countries of the world, although with different gradients. CONCLUSIONS: The standardized mortality rates for colon and rectum neoplasias presented important regional differences among Brazilian State capitals. The highest rates were observed in the South and Southeastern regions. A trend of increment of the standardized mortality rates for cancers of the colon and the rectum was observed in all Brazilian regions in the period 1980-1997.

Factors influencing the development of osteonecrosis in patients treated for slipped capital femoral epiphysis.

BACKGROUND: Osteonecrosis is a serious complication of the treatment of slipped capital femoral epiphysis. The purpose of the present study was to identify factors influencing the development of osteonecrosis. METHODS: Two hundred and forty patients who had been treated for slipped capital femoral epiphysis between 1965 and 1999 were retrospectively evaluated. Treatment included stabilization with a spica cast or fixation with one to four pins or screws. Radiographs that had been made at the time of presentation, before and after the operation, and at consecutive follow-up examinations were reviewed. Osteonecrosis was defined retrospectively on the basis of radiographic evidence of sclerosis and collapse of the femoral head. The risk of development of osteonecrosis was correlated with various clinical and radiographic parameters. RESULTS: All twenty-one patients in whom osteonecrosis developed had presented with an unstable slipped capital femoral epiphysis. None of the 204 patients who had presented with a stable slipped capital femoral epiphysis, regardless of grade, had development of osteonecrosis. In the group of patients who had presented with an unstable slipped capital femoral epiphysis, the risk of development of osteonecrosis increased with the severity (grade) of the slip. Osteonecrosis was more likely to develop in patients who had been treated with multiple pins than in those who had been treated with a single cannulated screw. CONCLUSIONS: Patients who have a stable slipped capital femoral epiphysis are not at risk for the development of osteonecrosis when treated with pinning in situ. Patients who have an unstable slipped capital femoral epiphysis have a decreased risk of osteonecrosis when treated with pinning in situ. Complete or partial reduction of an unstable slipped capital femoral epiphysis increases the risk of development of osteonecrosis. Pinning in situ without reduction with a single cannulated screw is the method of choice for the treatment of a slipped capital femoral epiphysis.

Capitalism ex cathedra. Sources of hope in tough economic times.

Pope John Paul II's encyclical Centesimus Annus--written in honor of the centennial anniversary of Rerum Novarum, the first papal social encyclical--examines the present world socioeconomic situation in light of traditional Catholic social teaching. The pope warns the West not to be too quick to celebrate the demise of communism as a victory for capitalism. Capitalism has some good points, the pope acknowledges, but by themselves, market mechanisms do not ensure the just distribution of food and other goods that fulfill essential human needs. When capitalism relies on market forces alone, it creates a culture of consumerism that promotes selfishness and greed. Capitalism has been in flux for decades. After World War II, developed Western societies began moving toward "Keynesian capitalism," which subjects the mechanisms of the free market to public control. After Keynesian capitalism's apparent failure in the United States in the 1970s came the "monetarist" theory and a return to an earlier, liberal form of capitalism in which society relies on market mechanisms alone to revitalize the economy and regulate the production and distribution of goods. The monetarist policies of the 1980s turned out to be part of a global plan to reorganize the economy around the giant multinational corporations. This forced individual countries to compete for capital investment and led to unemployment and neglect of low-income people. Structural adjustment policies have been adopted by governments all over the world, in poor countries as well as developed. All are moving toward the form of capitalism that is repudiated by Catholic social teaching in general and Centesimus Annus in particular.

Capital versus talent. The battle that's reshaping business.

For much of the twentieth century, labor and capital fought bitterly for control of the industrialized economy. The titans of industry ultimately won a resounding victory over the unions, but the story doesn't end there. In today's economy, value is largely the product of knowledge and information. Companies cannot generate profits without the ideas, skills, and leadership capabilities of knowledge workers. It's these factors--not technologies, not factories, and certainly not capital--that give the most successful companies their unique advantages. As knowledge workers come to realize this, and see that the demand for their talent outstrips the supply, they are steadily wresting more and more of the profits from shareholders. This time the battle is between the sources of capital and the producers of value, and how it will end is far from clear. The roots of the current conflict lie in the twentieth-century shift from industrial to managerial capitalism and the creation of a new class of professional talent, the authors explain. Since the arrival of the information-based economy in the past decade, tensions have escalated. The dramatic rise of CEO pay--and the public fire it has drawn--is a telling symptom. With this new battle, we're also witnessing a fundamental change in the political alignment of capital. The Left is now siding with "the common shareholder" against the well-compensated top tier of the labor pool. Shareholders seeing an unprecedented proportion of the return on their investments siphoned off to employees may well ask, is there no end to it? Increasingly, it's human capital that is the basis of value, and financial capital has become far more generic than shareholders would like to believe. The growing tensions between shareholders and managers cannot be ignored, and capitalism is at a crossroads--again.

Psychological Capital and Perceived Stress in Nurses: The Mediating Role of Need for Recovery and Recovery Experiences.

AIM: To examine whether recovery experiences and need for recovery mediate the association between psychological capital and perceived stress in nurses. DESIGN: Cross-sectional online survey. METHODS: A total of 184 nurses currently practicing in France completed an anonymous online questionnaire administered in January 2023. Participants completed the French versions of the Psychological Capital Questionnaire, the Recovery Experience Scale, the Need for Recovery Scale, and the Perceived Stress Scale. Two mediation models were estimated using ordinary least squares regression with percentile bootstrap inference for the indirect effects. RESULTS: Psychological capital was positively associated with recovery experiences and negatively associated with need for recovery. Need for recovery was strongly and positively associated with perceived stress, while psychological capital showed no direct association with perceived stress. The indirect effect of psychological capital on perceived stress through need for recovery was statistically detectable, whereas a complementary indirect effect through recovery experiences was in the expected direction but did not meet the bootstrap criterion for statistical significance. CONCLUSION: In this cross-sectional sample, psychological capital was associated with lower perceived stress primarily through its association with reduced need for recovery rather than through a direct association with stress. Interventions intended to protect nurse well-being should therefore be conceived as combining individual resource-building with organizational architectures that enable effective recovery. IMPLICATION FOR NURSING PRACTICE: Psychological capital should be seen as one element in integrated interventions rather than a stand-alone solution to nursing stress. Brief recovery-focused interventions for nurses need to be combined with scheduling practices and organizational policies that protect rest and make recovery feasible, a configuration that appears more promising than psychological capital training alone. REPORTING METHOD: The study followed the STROBE Statement for the reporting of cross-sectional studies. NO PATIENT OR PUBLIC CONTRIBUTION: This study focused on nurses as study participants. No patient or public stakeholder was involved in the design, conduct, or interpretation of the research, since the research question concerns occupational psychological resources rather than clinical practice or care delivery.

Changes in the referral pattern of child patients from the GDS to the CDS following the introduction of capitation in October 1990. General Dental Services. Community Dental Services.

OBJECTIVE: To observe the changes in the criteria for, rate of, and pattern of, referral of child patients from the General Dental Services (GDS) to the Community Dental Services (CDS) which may have occurred following the introduction of capitation as the method of remuneration for general dental practitioners (GDPs) for the treatment of child patients in The new contract 1990. DESIGN: GDP referral criteria and attitude to capitation were assessed in two districts (North Downs and Weybourne Trusts) using a questionnaire distributed to 179 GDPs. Reasons for referral, and treatment received within the CDS, were collated from the dental records of referred children, before and after the introduction of capitation. RESULTS: The response rate from the GDPs was 87%, of whom 82% had referred child patients to the CDS. The results showed that 65% of GDPs indicated a preference for treatment of children under a fee per item system, whereas only 17% favoured capitation. Although 60% believed that their referral of patients to the CDS had not changed following capitation, an analysis of the referred children's dental records revealed that there had actually been a 57% increase in the number of referrals from GDPs to CDS following the introduction of capitation. The GDPs considered the most important referral criteria were for non cooperation or general anaesthesia. More cooperative children had been referred and more routine restorative procedures, less inhalation sedation and deciduous extractions were carried out following the introduction of capitation. CONCLUSIONS: This study has shown that following the introduction of capitation there had been an increase in the number of referrals from the GDS to the CDS.

Does capitated contracting improve efficiency? Evidence from California hospitals.

This study examines the effect of capitated contracting on hospital efficiency to better understand strategies related to the recent financial crisis in the California health care market. Our findings indicate that less efficient hospitals are more likely to participate in capitated contracting. As a result, hospitals with capitated contracts are, on average, less efficient than hospitals without capitated contracts. Hospital efficiency generally increases with respect to the degree of capitation involvement. The efficiency improvement, however, becomes insignificant when capitation exposures are already high. Thus, hospital executives should not be overly optimistic about efficiency gains obtained in capitated contracting and should control the degree of capitation involvement.

Is provider capitation working? Effects on physician-hospital integration and costs of care.

BACKGROUND: Capitation holds health providers fiscally responsible for the services they deliver or arrange and thus provides strong motivation for physicians and hospitals to integrate activities and reduce costs of care. OBJECTIVES: The objective of this study was to assess 2 potential effects of capitation: (1) its effects on the integration of functional, financial, and clinical processes between hospitals and physicians and (2) its effects, in conjunction with process integration, on hospital costs. STUDY DESIGN: We studied a 1995 American Hospital Association (AHA) special survey that has information on 44 different physician-hospital integrative activities and on global capitation contracts held by management service organizations, physician-hospital organizations, and other similar entities. These data were combined with the AHA's Annual Survey of Hospitals, InterStudy HMO data, the area resource file, and state regulation data. Multivariate analysis was used to assess the relationship between capitation and integration and then to examine the influence of these factors and others on hospital costs. We studied 319 urban hospitals with complete data. FINDINGS: Provider capitation was found to promote integration between hospitals and physicians in relation to administrative/practice management, physician financial risk sharing, joint ventures to create new services, computer linkages, and an overall measure of physician-hospital integration. However, anticipated effects of integration and capitation on hospital costs were not evident. CONCLUSIONS: Global capitation is motivating tighter integration between physicians and hospitals in a number of respects. Although capitation is currently having the intermediate effect of encouraging process integration, it is not yet having the ultimate anticipated effect of lowering hospital costs.

Capital budgeting techniques.

The cost of new medical imaging equipment for a radiology practice is a major capital purchase. Due to rapid advances in technology and imaging techniques, the management decision to purchase new capital equipment can present itself every few years. The present report explains various financial management techniques that are generally used by corporations worldwide to determine their cost of capital. The cost of capital is the return on a capital investment project required by the providers of the capital. The published financial accounts of Sonic Healthcare Limited, Australia's largest pathology company, are reproduced as a numerical example of how the financial accounts of a business may be used to determine its cost of capital. The cost of capital forms an integral part of management's financial decision-making process.

Characteristics of dentists participating in capitation and Preferred Provider Organization dental plans.

BACKGROUND: In 1998, the American Dental Association Survey Center conducted a telephone and mail survey of U.S. dentists in private practice in an effort to determine the extent of dentists' participation in capitation and preferred provider organization, or PPO, dental plans and the characteristics of dentists who participate in those plans. METHODS: An initial telephone screening survey of a random sample of 11,550 dentists in private practice was conducted to identify dentists who participated in PPO or capitation dental plans. Dentists who participated in either of these plan types then were asked to complete a mail survey on their plan participation. RESULTS: The majority of dentists participating in either type of dental plan reported having never left a dental plan. Dentists who belonged to more than one PPO or capitation plan reported that a larger percentage of their patients were enrolled in these plans and that more of their practice's gross income came from the plans. Participation in PPO and capitation plans has had a positive impact on the practices of many of the responding dentists, particularly with regard to expanding their patient base. CONCLUSIONS: The authors found that the majority of dentists participating in PPO dental plans found it to be a positive experience overall. Dentists participating in capitation plans were less satisfied; more than 50 percent of capitation plan participants reported some level of dissatisfaction with the plans. The majority of dentists participating in a PPO plan expected to renew participation when their current contract expired; a much smaller percentage (though still a majority) of responding capitation-plan participants indicated the same. PRACTICE IMPLICATIONS: Responding dentists' overall indication of satisfaction with their current PPO plan participation probably indicates further growth for these dental plans. On the other hand, capitation plan participants seem much less satisfied with their plans. PPO plans, therefore, seem much more likely to be the type of plan that dentists will choose in the future.

The integrated supplier: key to cost management and multi-franchise capitation contracting.

Capitation...most healthcare providers do not work under it, comprehend it, or even want it, yet supply capitation contracting seminars are popping up everywhere creating the feeling that the bandwagon is leaving, and it might be time to get on board. Not true. Supply capitation is not for all organizations. Capitation contracting is not easy and there are not many successful models to help the uninitiated. If a panacea is sought for reducing supply costs, capitation is only one component of a systematic strategy to reduce materiel costs. This article suggests a direction using the Group Health Materiel Management (Group Health Cooperative of Puget Sound, WA) experience as a point of reference. It advocates a systematic approach that focuses on expense reduction in: cost of goods, holding cost of inventory, labor cost associated with all materiel processes, distribution cost (transportation and par stock pick, pack, and replenishment), product utilization, variation in product standards, and waste stream byproducts. At Group Health (GH) these issues are primarily addressed through the use of: information systems, supplier certification/selection processes, group purchasing compliance, supply channel management, supply capitation contracting programs, standardization, and utilization management. Because of managed care organizational structure, Group Health Cooperative supply capitation contracting, as performed at GH, is discussed not as a quick fix solution but in the spirit of sharing our experience with others who may be considering it as a cost savings tactic in the context of a broad-based materiel management strategy. This article highlights the experiences of GH beginning with materiel management's business process assumptions toward multiple-franchise supply capitation.

The impact of capital payment options under Medicare prospective payment. An ECRI technology management assessment.

In view of the upcoming legislative deadline for inclusion of capital costs within the Medicare prospective payment system, both public and private-sector entities have scrutinized various capital payment options and debated key issues relating to appropriate overall payments for capital costs, the nature of the mechanism for allocating payments to hospitals, and the method for transition from the present to the new capital payment system. The new capital payment policy will play an important role in future hospital capital decisions and technology levels. This report describes the nature and magnitude of hospital capital costs, examines alternative proposals for reflecting capital costs in the Medicare prospective payment system, and details each alternative's impact, incentives, and disincentives.

Health capital policy in the United States: a strategic perspective.

Health capital policy is strategically important not only because of the long-term nature of capital commitments but also because capital requirements often drive institutional behavior far out of proportion to dollars expended. The authors offer a framework for analyzing U.S. health capital policy, much of which is indirect and not always understood to be health capital policy. They emphasize the complex interaction between capital policy and health system configuration and performance, and highlight the long-term effects of current capital policy. They conclude with a likely configuration of the future U.S. health care system and with a discussion of the strategic role of capital policy in creating that future.

Cultural capital and self-rated health in low income women: evidence from the Urban Health Study, Beirut, Lebanon.

This paper examines the association between cultural capital and self-rated psychosocial health among poor, ever-married Lebanese women living in an urban context. Both self-rated general and mental health status were assessed using data from a cross-sectional survey of 1,869 women conducted in 2003. Associations between self-rated general and mental health status and cultural capital were obtained using chi (2) tests and odds ratios from binary logistic regression models. Cultural capital had significant associations with self-perceived general and mental health status net of the effects of social capital, SES, demographics, community and health risk factors. For example, the odds ratios for poor general and mental health associated with low cultural capital were 4.5 (CI: 2.95-6.95) and 2.9 (CI: 2.09-4.05), respectively, as compared to participants with high cultural capital. As expected, health risk factors were significantly associated with both measures of health status. However, demographic and community variables were associated with general health but not with mental health status. The findings pertaining to social capital and measures of SES were mixed. Cultural capital was a powerful and significant predictor of self-perceived general and mental health among women living in poor urban communities.
