Automated determination of salts in water-soluble certifiable color additives by ion chromatography.

A previously developed ion chromatographic method for the determination of salts in water-soluble certifiable color additives was automated, using a Model 12 Dionex ion chromatograph equipped with a program controller and programmable computing integrator. Programs were written for the program controller for continuous automated analysis of up to 59 samples in about 20 h, with periodic regeneration of the suppressor column and automatic shut-down. All data were processed through the integrator, programmed to give results in weight/weight percent. Recoveries were performed on 4 anions: chloride, phosphate, bromide, and sulfate. Twenty-five color additives could be analyzed by the method. Standard deviations in the determinations ranged from 0.01 to 0.16 at addition levels of 0.20-9.45% with 6 replications. Recoveries for addition levels of 0.2-5.0% with 2 replications fell within the range of 84.0-105.0%. Approximate lower limits of detection for each anion were as follows: chloride, 0.07%; phosphate, 0.10%; bromide, 0.06%; sulfate, 0.07%.

[Features of the hemodynamics of myocardial infarct patients undergoing the most widely used rehabilitation programs].

Integrated body rheography, radiocardiography and radionuclide ventriculography were used to investigate hemodynamic changes in 101 myocardial infarction patients during the hospital stage of the disease. Changes in major hemodynamic parameters were demonstrated by the end of the 1st week and when walking was resumed. At the resumed-walking stage, the mechanism of declining stroke and cardiac indices was shown to depend on physical activation rates. Hemodynamic response is mostly conditioned by myocardial insufficiency when walking is resumed rapidly during the 2nd week, and by smaller venous return due to hypovolemia where it is resumed slowly during the 4th week. Expanding motion regimens at slow rates results in persistent hemodynamic disturbances in myocardial infarction patients.

Effectiveness of a sensory integrative therapy program for children with perceptual-motor deficits.

This study was an evaluation of the sensory integrative therapy (SIT) program (Ayres, 1972a) for children at the Christchurch Hospital. Fifty-five children were randomly assigned to the SIT program, a parallel physical education program, or to a no-treatment condition. The children were assessed before and after treatment on measures of perceptual-motor development, language and reading development, self-concept, and handwriting skills. Covariance analysis, with age and pretest scores as covariates, found no significant differences between groups on any of the measures except reading progress among those children who could already read at the beginning of the program. Children who made the least progress during therapy were those who (a) had epilepsy, (b) were from a low-income, single-parent family, or (c) had behavioral problems.

Identification of rice cultivars resistant to Lissorhoptrus oryzophilus (Coleoptera: Curculionidae), and their use in an integrated management program.

The rice water weevil, Lissorhoptrus oryzophilus Kuschel, is the most destructive insect pest of rice in the United States and is a particularly severe pest in Louisiana. The current management program for this insect in Louisiana relies heavily on insecticides, most notably the seed treatment fipronil (Icon). Diversification of the management program by incorporation of alternative strategies is needed to improve the effectiveness and long-term stability of the program. In the three experiments reported here, three components of a diversified management program for the rice water weevil in Louisiana--host plant resistance, treatment of seeds with Icon, aid the cultural practice of delayed flooding--were investigated. Comparison of the densities of weevil larvae on the roots of several commercial cultivars indicated that the long-grain cultivar 'Jefferson' was more resistant to infestation by the rice water weevil than the other cultivars. The medium-grain cultivars 'Bengal', 'Earl' and 'Mars' and the long-grain variety 'Cocodrie' were the most susceptible to infestation. Comparison of yield data from untreated plots and plots treated with Icon indicated that the long-grain cultivars Cocodrie, Lemont, and Jefferson were more tolerant of weevil injury than the other cultivars. A 2-wk delay in flooding was associated with yield benefits in plots not treated with Icon. Treatment of seeds with Icon controlled weevils in all three screening experiments. The implications of these results for the development of an integrated management program for the rice water weevil are discussed.

The Duke University program for integrating ethics and human values into medical education.

In its second year of development, this program blends cognitive and affective approaches to integrating ethics and human values into medical education. The core of this effort is the establishment of direct and continuing relationships between the four advisory deans and their medical student advisees through small groups that continue throughout the four years of medical school. Clinical correlation seminars, lecture/discussions, the humanities, clinical clerkships, and electives are components of this integration process. Both basic science and clinical faculty members have observed positive changes in the degree and depth of participation, discussion, and interest, as well as in the general attitudes of the students.

Urinary schistosomiasis in southern Ghana: a logistic regression approach to data from a community-based integrated control program.

The data for this analysis are based on the schistosomiasis control project of the Noguchi Memorial Institute for Medical Research, University of Ghana, Legon, Ghana, designed to study the feasibility and effectiveness of an integrated schistosomiasis control program. It embraced chemotherapy and health education for community motivation. The study was carried out from 1993 to 1997. This paper presents observations made 24 months after intervention. Eight communities in southern Ghana were grouped into three areas. Individuals in all the areas received praziquantel after the baseline data collection in 1992-1993. Area 1 had passive while Area 3 received active health education. Area 2 received no education. Prevalence of schistosomiasis was the response variable of interest while age, sex, and area were considered as possible influencing variables. The model for the baseline data indicated no significant difference in prevalence among the three areas. The model 24 months after intervention indicated a significant difference among the three areas, suggesting a possible influence of the health education that motivated community participation in the provision of facilities for the control of schistosomiasis.

Beyond a code of ethics for bioengineers: the role of ethics in an integrated compliance program.

Developing a code of ethics for biomedical engineering professionals is a very important first step in clarifying their professional obligations and in helping to establish and maintain their professional autonomy. However, it is only that--a first step. Unless ways can be found to bring the principles contained in this code to bear on the everyday decision making of these professionals, this code will have little practical influence. One effective way to bring a code of ethics to bear on decision making is to integrate it into organizational compliance programs. Such programs often have company-specific codes of ethics attached to them, and these company-specific codes can either include the principles contained in the professional code of ethics or reference the code by title. After defining what I take to be the challenge of compliance, I consider four (4) roles that codes of ethics and ethics generally can play in helping to create and sustain programs at the organizational level that integrate ethics and compliance and thereby aim to make a practical difference in the everyday decision making of bioengineering professionals. These four roles include: framing the program, grounding the standards, achieving critical distance, and creating and sustaining an ethical organizational culture.

Adherence to worksite exercise programs: an integrative review of recent research.

1. Improving worker physical fitness through worksite exercise programs offers many benefits to the employee and the employer. Unfortunately, a small percentage of workers who begin an exercise program adhere to it. 2. It is essential to design program strategies to promote exercise adherence among persons who do not currently exercise at levels that achieve health benefits. 3. The results of this review of worksite research suggest a number of strategies that were successful in increasing at least short term exercise adherence. 4. Carefully controlled studies are needed to identify specific worksite exercise interventions or combination of interventions that maximize the initiation of exercise as well as short and long term adherence. A combination of strategies improves exercise adherence for at least 6 months, but more research is needed to determine long term maintenance of an exercise program.

The future for mental health in primary health care programs.

Our largely separate mental health system has developed in relationship to a health care system oriented toward specialization and solo practice. Now the health care system is moving in the direction of primary care and group and organizational practice. New forms of mental health delivery are needed to maximize the potential of these new health care programs for mental health services. The author describes these new integrated programs which bring mental health providers into the primary health care programs for direct services as well as consultation. Issues discussed include mutual roles, changes in services, the referral process, and provider relationships. The advantages of such integrated programs include decreased stigma, increased prevention through earlier detection and referral, increased family orientation, greater coordination of care, and less duplication.

ARCADIA reveals spatially dependent transcriptional programs through integration of scRNA-seq and spatial proteomics.

MOTIVATION: Cellular states are strongly influenced by spatial context, but single-cell RNA sequencing (scRNA-seq) loses information about local tissue organization, while spatial proteomic assays capture limited marker panels that constrain transcriptomic inference. Integrating these modalities can elucidate how spatial niches shape transcriptional programs, yet existing approaches depend on either feature-level correspondence such as gene-protein linkage or cell-level barcode pairing, which is often unavailable. RESULTS: We present ARCADIA (ARchetype-based Clustering and Alignment with Dual Integrative Autoencoders), a generative framework for cross-modal integration that operates without cell barcode pairing and does not assume direct feature-to-feature correspondence. ARCADIA identifies modality-specific archetypes, that is, convex combinations of cells representing extreme phenotypic states, and aligns these anchors across modalities by minimizing the discrepancy between their cell-type composition profiles. The aligned archetypes define a shared coordinate system that anchors dual variational autoencoders (VAEs) trained with cross-modal geometric regularization, preserving archetype structure and spatial neighborhood information while enabling bidirectional translation between modalities. On semi-synthetic CITE-seq data, ARCADIA outperforms existing weak-linkage methods. Applied to independent human tonsil scRNA-seq and CODEX data, ARCADIA reconstructs known tissue architecture and reveals spatially dependent transcriptional programs linking B-cell maturation and T-cell activation or exhaustion to microenvironmental niches.

Assessing the success of the WomanKind program: an integrated model of 24-hour health care response to domestic violence.

PURPOSE: The WomanKind program, a non-profit health care based program for for victims of domestic/intimate partner violence (IPV), seeks to enable and motivate health care providers to identify victims of such violence and refer them to WomanKind's in-house services. An evaluation designed to assess client referral to WomanKind services and the impact of health care provider training was carried out. METHODS: Data were collected at three intervals over a 2-year period at 3 intervention and 2 comparison hospitals located in Minneapolis, MN. The focus of data collection efforts was to assess the providers' knowledge, attitudes, beliefs, and behaviors (KABB) concerning identification and referral of victims of IPV. Hospital staff and volunteer advocate training programs also were evaluated. Chart reviews were conducted and client referrals assessed. RESULTS: Providers at WomanKind hospitals demonstrated significantly higher knowledge, attitudes, beliefs and behaviors than those at comparison hospitals throughout the study. During the data collection period, 1719 IPV victims were identified and referred to the WomanKind program, while only 27 IPV victims were referred to trained social workers at the comparison hospitals. Chart reviews indicated that emergency staff at the intervention sites provide documentation of IPV in patient records twice as frequently as emergency staff at the comparison sites. CONCLUSION: This research underscores the efficacy of a well-structured, multidisciplinary effort to deliver services to IPV victims. The results demonstrate that specialized training and on-site client services create a significant positive impact on the KABB of health care providers.

IAEA/EPA international climatic test program for integrating radon detectors. International Atomic Energy Agency/Environmental Protection Agency.

As an element of the joint IAEA-EPA International Radon Metrology Evaluation Program, a climatic test of long-term integrating radon detectors was conducted at the U.S. EPA Radiation and Indoor Environments National Laboratory. The objective of this study was to test the performance of commonly used commercially available long-term 222Rn detector systems under extreme climatological conditions using filtered polycarbonate CR-39 plastic analyzed by the manufacturer using the track-etch method, unfiltered LR-115 film analyzed by the manufacturer, and Teflon based electrets analyzed in the field by EPA using the manufacturer's equipment. The EPA environmental radon chambers were used to expose detectors to extreme cold and dry (less than 4.0 degrees C air temperature and 25% relative humidity) and hot and humid (greater than 35 degrees C air temperature and 85% relative humidity) climatic conditions. During phase I detectors were exposed to low temperatures and low humidities, and during phase II detectors were exposed to high temperatures and high humidities. Typical indoor equilibrium fractions (near 50%) and radon concentrations of about 150 Bq m(-3) were maintained for each phase, which lasted 90 d. The results indicated that the optimal detector for extreme climatic conditions is dependent on the relative importance of bias and precision. Overall, however, the filtered track-etch type detector produced the most reliable results under the extreme conditions.

The impact of a multidisciplinary breast cancer center on recommendations for patient management: the University of Pennsylvania experience.

BACKGROUND: Advances in the diagnosis and treatment of breast carcinoma have led to a multidisciplinary approach to management for patients with breast carcinoma. To assess the effect of this approach, the authors performed an evaluation for a cohort of patients examined in a multidisciplinary breast cancer center. METHODS: An analysis was performed for the records of 75 consecutive women with 77 breast lesions examined in consultation in a multidisciplinary breast cancer center between January and June 1998. Each patient's case was evaluated by a panel consisting of a medical oncologist, surgical oncologist, radiation oncologist, pathologist, diagnostic radiologist, and, when indicated, plastic surgeon. A comprehensive history and physical examination was performed, and the relevant mammograms, pathology slides, and medical records were reviewed. Treatment recommendations made before this evaluation were compared with the consensus recommendations made by the panel. RESULTS: For the 75 patients, the multidisciplinary panel disagreed with the treatment recommendations from the outside physicians in 32 cases (43%), and agreed in 41 cases (55%). Two patients (3%) had no treatment recommendation before consultation. For the 32 patients with a disagreement, the treatment recommendations were breast-conservation treatment instead of mastectomy (n = 13; 41%) or reexcision (n = 2; 6%); further workup instead of immediate definitive treatment (n = 10; 31%); treatment based on major change in diagnosis on pathology review (n = 3; 9%); addition of postmastectomy radiation treatment (n = 3; 9%); or addition of hormonal therapy (n = 1; 3%). CONCLUSIONS: The multidisciplinary breast cancer evaluation program provided an integrated program in which individual patients were evaluated by a team of physicians and led to a change in treatment recommendation for 43% (32 of 75) of the patients examined. This multidisciplinary program provided important second opinions for many patients with breast carcinoma.
