The epitaxially induced crystal growth of calcium oxalate by crystalline uric acid

The forces which have and are producing change in dietetics are recapitulated, as are developments in the profession which have evolved since 1972 when the Study Commission on Dietetics made its report. The coordinated undergraduate program in dietetics has gained much ground; in 1972, there were but seven such programs. Today there are forty-three. More than three hundred traineeships are currently preparing over five hundred trainees to take their places in the profession. Another facet of training involves programs for dietetic technicians and dietetic assistants, designed to open up the career ladder concept. Continuing education is of prime importance for those beyond the entry-level of competence. The dietitian's first responsibility is to society, preceding that for the profession-as has been plainly indicated in a number of A.D.A. Position Papers and the emphasis of the Association in its legislative thrust on the value of nutrition education in preventive health care. Concern of the Association about the competency of practicing dietitians has also been reflected in the early appointment of a Committee on Professional Standards Review. The Association, as a member of the National Nutrition Consortium, is an advocate for a "National Nutrition Policy" and must continue to work for recognition that nutritional care is basic to comprehensive health care.     

Cultural variation in affect valuation.

The authors propose that how people want to feel ("ideal affect") differs from how they actually feel ("actual affect") and that cultural factors influence ideal more than actual affect. In 2 studies, controlling for actual affect, the authors found that European American (EA) and Asian American (AA) individuals value high-arousal positive affect (e.g., excitement) more than do Hong Kong Chinese (CH). On the other hand, CH and AA individuals value low-arousal positive affect (e.g., calm) more than do EA individuals. For all groups, the discrepancy between ideal and actual affect correlates with depression. These findings illustrate the distinctiveness of ideal and actual affect, show that culture influences ideal affect more than actual affect, and indicate that both play a role in mental health.

Induction of sensitivity to NK-mediated cytotoxicity by TNF-alpha treatment: possible role of ICAM-3 and CD44

The paper examines possibilities for employing more holistic approaches to the evaluation of health care programs. It is argued that the reductionism of conventional forms of economic evaluation, where value (or benefit) is seen in terms of either health consequences or individuals' utility, can cause a number of aspects of such programs to be overlooked. As such, this imposes fairly strict limits on the capacity of economic evaluation to inform public policy. In contrast, institutionalist economic theory in common with the community development approach to health promotion is an area of research which acknowledges that change to the broader socio-political environment can be a source of value. It is suggested that this idea has, for instance, significance for the evaluation of indigenous health programs where notions of "cultural appropriateness" have strong influence over the effectiveness and acceptability of such programs. It is concluded that no one evaluative approach is appropriate in all situations and that a greater receptiveness to broader sources of social value can help to improve the way evaluations are conducted.     

Lessons in transferring resources: the system of fees per patient

Dowries can be defined as lump sum payments or continuing grants which health authorities make between themselves and to local authorities or voluntary organisations in respect of people with severe mental disorders to be cared for in the community instead of in hospital. This paper has three aims. First to describe how dowries and other processes were set up to encourage the closure of two psychiatric hospitals in England. The broader financing context for mental health care (prior to the reforms in England engendered by the NHS and Community Care Act, 1990) is also described and shows some similarities to the current arrangements in Québec. Second, we abstract some information from a long-running evaluation of the reprovision programme to look at the type of services used in the community by former long-stay patients of these two hospitals and the comparative costs of hospital and community-based care. After leaving hospital, former patients require considerable inputs from other health and social care services; any development of community care for these patients should at the least mirror the facilities provided on the hospital campus. The final aim of this paper is to examine the extent to which this English system of budget reallocation ("dowries") can be employed in Québec to further reduce long-stay hospital provision. There are many similarities between the health and social care systems of the two countries but there are also organisational and political differences. It is not sensible, therefore, to transfer the English budget reallocation to Québec wholesale, but we suggest that there are important process and implementation issues which can guide the development of financing mechanisms in Québec.     

A critical examination of gender differences in nutritional risk for rural adults with disability.

Objectives: To examine gender differences in nutritional risk for rural adults with disability. To identify specific perceived nutrition barriers that intervention programs might target among rural adults with disability. Study Design: Telephone interviews. Participants: One hundred twenty-four rural adults from Meals-on-Wheels and Center for Independent Living programs (46 men, 78 women; mean age = 57.7 years, 96% Caucasian). Outcome Measures: Nutrition Screening Initiative, Nutritional Risk Index, Perceived Nutrition Barriers Scale. Results: Women reported greater nutritional risk on all measures, but gender differences appeared mediated by age and disability. Top barriers were identical for men and women. Conclusions: Rehabilitation psychologists should consider age and disability first, rather than gender-related assumptions about nutritional risk. Nutrition intervention should encourage shared food cost, transportation, preparation, and new tastes. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Personality-structure in different kinds of bronchial asthma (author's transl)

The "Giessen-Test" is a psychological test in form of a questionnaire, basing on self-assessment. It was applied in 63 patients with bronchial asthma in order to get their "self-images" and their "ideal-self-images". Except of higher values for depression the "self-images" of the asthmatics resembled very closely those of normals. The ideals ("ideal-self-image") of the patients were uncharacteristic and reflected general trends. In contrast to these findings eleven physicians had a negative conception of asthmatic patients ("foreign image"). Physicians assessed the asthmatics to be disliked ("negative social resonant"), obstinate ("dominant") and depressive. Patients with exogen-allergic asthma, intrinsic asthma and asthma of unknown origin differ from each other only within a few marks. These differences, however, are not sufficient, to allow to coordinate a specific personality-structure with one of the different kinds of asthma.     

Capuchin monkeys, inequity aversion, and the frustration effect.

Each of 4 female capuchin monkeys ("model") was paired with another female capuchin ("witness") in an adjacent cage. In Phases 1 and 3, a model could remove a grape from the experimenter's hand while the witness watched. The witness was then offered a slice of cucumber, a less preferred food. Trials alternated between subjects 50 times, defining a session. In Phases 2 and 4, both were offered cucumber. Witness rejections of cucumber were infrequent and were not dependent on whether models received grape or cucumber. When models were offered cucumber, they rejected it at higher rates than did witnesses. These results fail to support findings of Brosnan and de Waal. An account based on the frustration effect accommodates these results and those of Brosnan and de Waal. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Weight loss in Alzheimer's disease: an international review of the literature

Alzheimer's disease affects an estimated 2 million elderly in the U.S. and challenges primary care physicians to assist caregivers in dealing with the daily management of these patients. To support the clinical observation of weight loss in Alzheimer patients despite adequate food intake, we reviewed the existing literature. To date, eight international studies have focused on nutrition in Alzheimer's disease and all have found weight loss. It is not clear whether this weight loss is a component of or a consequence of the disease. These findings suggest systemic, metabolic alterations in Alzheimer's disease. They require further investigation as to their nature and as to their appropriate recognition and management to retard the deteriorating effects of chronic weight loss and malnutrition. Finally, some reports lead to speculation that nutritional strategies may improve cognitive function.     

Determination of clonazepam ("Rivotril" or "Ro 5-4023") in plasma by gas chromatography using an internal standard

A method has been developed for gas-chromatographic determination of clonazepam ("Rivotril" or "Ro 5-4023") in plasma, using methyl-clonazepam ("Ro 4082") as an internal standard. Following extraction of the benzodiazepines and hydrolysis, the benzophenones are analyzed by gas-chromatography, using a glass column filled with 3% OV 225 on Gas Chrom Q and a 63Ni electron-capture detector. The technique has good selectivity. The limit of sensitivity is less than 1 ng/ml of plasma. Using this method the plasma kinetics of clonazepam may be studied in man and the correlations between plasma levels and therapeutic activity investigated. It is also available for toxicological analysis, as well as pharmacovigilance purpose. The same internal standard and a similar method can also be used for the determination of flunitrazpem ("Rohypnol" or "Ro 5-4200") and its major metabolite (N-desmethyl-flunitrazepam) in plasma.     

Nutrition support for the elderly

The increasing size and longevity of the geriatric patient population dictates that all health care practitioners become more cognizant of the unique requirements for nutritional assessment and support of the elderly. This review summarizes recent advances in the understanding of the nutrition support needs of the old and oldest-old patients requiring enteral or parenteral feeding. When a nutrition support formula individualized for the geriatric patient is being developed, there is a fine line between excess and deficit, requiring the involvement of the entire support team in monitoring the success of feeding. Indications for choosing enteral or parenteral feeding are considered excessively invasive by some and necessarily "heroic" by others. The patient and his or her family should be part of the decision-making process.     

A cross-cultural, multidisciplinary proof of the newly discovered developmental linguistic law of concordance of speech and motor development in children.

Humorously describes fictional studies "proving" that motor and language development occur concurrently ("hand in hand") and that this development is independent of culture. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Rehabilitation Psychologist as Health Care Executive: A Platform for Professional Diversification.

These are the best and worst of times in health care. Technological advances are offset by critical staff and cash shortages. Strong leadership is needed to navigate these challenges, yet the industry faces a widening leadership void. The effective psychologist possesses 5 specific competencies ("planks") that are well matched for success as a health care executive: clinical, relational, analytical, methodological, and ethical. By applying these competencies, rehabilitation psychologists can enhance their organizations and open new pathways for personal and professional growth. A 6th competency, financial, represents a unique "give and take" position that is portrayed through a replication and extension of J. G. Wiggins's (1994) analysis of careers in psychology. It is concluded that advocacy for our clients, our field, and ourselves is served by rehabilitation psychologists' achieving health care executive positions.

Assessment of adherence with multiple informants in pre-adolescents with spina bifida: initial development of a multidimensional, multitask parent-report questionnaire

Long-term acute care and subacute care facilities (also transitional care facilities) have evolved from the need to decrease costs associated with acute care in the hospital. As the length of stay in many medical centers has been reduced, patients are admitted to transitional care facilities to continue recovery and rehabilitation. Rehabilitation and recovery can be enhanced with the provision of optimal medical nutrition therapy. Nutrition screening is essential in identifying patients who are at risk of malnutrition or are malnourished. Nutrition assessment verifies the risk or presence of malnutrition followed by the development, implementation, and monitoring of nutrition intervention. Nutrition screening and intervention promote recovery from illness, minimize morbidity and mortality, and enhance quality of life. The goals of nutrition support are to prevent starvation-associated malnutrition, preserve lean tissue mass, support metabolic functions, and improve clinical outcomes. Oral nutrition is the preferred method of nourishment; however, specialized nutrition support is considered for patients unable to meet their nutrient requirements adequately. Enteral nutrition support is recommended when providing nutrition support however, parenteral nutrition support is used when the gastrointestinal tract can not be safely used. With appropriate intention, administration, and monitoring, nutrition support can be safely administered.     

The causes, prevalence and clinical aspects of nutritional insufficiency

The health of a man is predetermined to a considerable extent by his nutrition. Army physicians frequently deals with the cases of insufficient nutrition among servicemen. The article studies the reasons, frequency and clinic aspects of insufficient nutrition. The authors give a historical reference about the notion of nutritional dystrophy, and reveals some mechanisms of its development. These considerations concerning the cases of insufficient nutrition in servicemen will help army physician to carry out a more effective preventive work among military contingency.     

Human immunodeficiency virus type 1 Vif-derived peptides inhibit the viral protease and arrest virus production

OBJECTIVES: The purpose of this study was to estimate the prevalence of food insufficiency in the United States and to examine sociodemographic characteristics related to food insufficiency. METHODS: Data were analyzed from the third National Health and Nutrition Examination Survey, a cross-sectional representative sample of the civilian noninstitutionalized population living in households. Individuals were classified as "food insufficient" if a family respondent reported that the family sometimes or often did not get enough food to eat. RESULTS: From 1988 through 1994, the overall prevalence of food insufficiency was 4.1% and was primarily related to poverty status. In the low-income population, food insufficiency was positively associated with being Mexican American, being under the age of 60, having a family head who had not completed high school, participating in the Food Stamp Program, and not having health insurance. It was not related to family type or employment status of the family head. Over half of food-insufficient individuals lived in employed families. CONCLUSIONS: Food insufficiency is not limited to very low-income persons, specific racial/ethnic groups, family types, or the unemployed. Understanding food insufficiency is critical to formulating nutrition programs and policies.     

Anxiety-like and depression-like behavior in Maudsley reactive (MR) and non-reactive (NMRA) rats

1. Female MR ("anxious") and MNRA ("non-anxious") Maudsley rats were tested in the CSD behavioral conflict paradigm (anxiety-like measure) and also in the FST paradigm (depression-like measure). 2. As expected, MNRA rats accepted significantly more shocks in the CSD paradigm than did MR rats (i.e., MNRA rats were less "anxious"), MNRA rats also exhibited significantly less immobility in the FST procedure (i.e., MNRA rats were less easily made "depressed"). 3. When the data were pooled across the two strains, there was a significant correlation between CSD and FST behavioral scores; however, there was no significant correlation between these measures when the data from the two strains were evaluated separately. Multiple regression (independent variables of rat strain and CSD score, dependent variable of FST score) revealed a significant effect of rat strain, but not CSD score, on FST behavior. 4. The relationship of these findings to the apparent relationship between anxiety and depression in humans is discussed.     

Control of cholesterol access to cytochrome P450scc in rat adrenal cells mediated by regulation of the steroidogenic acute regulatory protein

Using the mouth as an "in vivo articulator," the bilateral nonmasticatory ("empty") contact patterns of opposing cuspid and first molar teeth were determined in two healthy subjects with well-defined cuspid function and two healthy subjects with well-defined group function. The electronically recorded "empty" contact patterns pertained to the static intercuspal position and dynamic laterotrusion to the right and the left. On the basis of the "empty" tooth contact patterns and the number of electronically recorded masticatory cycles of one masticatory sequence, we postulated two simple models that attempted to predict the masticatory ("functional") tooth contacts of one sequence of unilateral mastication of apple and banana. Statistical comparisons between the predictions of the two models and the actual ("functional") contacts of in vivo mastication showed that the models predicted fairly well the observed tooth contacts on the nonchewing-side of the mouth, but not the observed tooth contacts on the chewing-side of the mouth. In consequence, "empty" (nonmasticatory) tooth contact patterns should not be equated with "functional" (masticatory) tooth contact patterns.     

Molecular pathology of acquired immunodeficiency syndrome-related non-Hodgkin''s lymphoma

The assumption that Amish cultural value of cooperation leads to greater longevity, prosperity and well-being among elders was examined using historical demographic and ethnographic analysis in a conservative Old Order Amish community. Migration, fertility, mortality and morbidity data since 1948 were used to identify population structure. The population pyramid in the Amish community (3% of the population over age 60, compared to 18% of the neighboring non-Amish rural area) is largely determined by natural fertility with low infant mortality. Household ethnography explored health beliefs, access to health care, caregiving patterns, and economic strategies. The perception that community cooperation and altruistic behavior were of benefit to Amish health is supported by mortality rates. Amish age standardized death rates were 19% below the US death rate in 1960. Migrating to form new communities and selectively utilizing acute (but not preventive or public) health care services, emerged as strong cultural patterns that facilitate reproductive success among the Amish.
