Uncharitable and out of control?

This article explores the current state of the law governing partnerships and other collaborations between tax-exempt health care organizations and private health care providers. The author sets out the regulatory maze through which exempt entities and private parties must navigate in attempting to maintain Internal Revenue Code (IRC) Section 501(c)(3) status for the exempt entity in these relationships. The article discusses and comments on general principles through an examination of case law, statutes, regulations, revenue rulings, revenue procedures, and information letters, as well as state law issues, with an emphasis on maintaining charitable purposes, effecting control, and dealing with ownership and compensation issues.     

Circumcision in the control of HIV?

Ken Rankin (AH, Jan '94, p 34) rightly points out that more circumcisions are carried out than are justified on clinical grounds alone. However, the advent of AIDS raises a number of interesting points about the possible role of circumcision as an epidemiological tool for the control of HIV transmission. It has been reported that an absence of circumcision increases susceptibility to acquiring STDs. STDs, especially those that cause genital ulcer disease (such as syphilis, chancroid and genital herpes), are recognized major risk factors for the transmission of HIV. Furthermore, some studies have shown that the distribution of HIV seroprevalence in Africa is closely associated with the geographical pattern of circumcision practices, whilst other workers have shown an association between absence of circumcision and HIV seropositivity. In some societies where circumcision was formerly practiced on religious/cultural grounds, it has now largely been abandoned as a consequence of urbanization and the adoption of Western lifestyles. In such situations, a revival of this ancient custom might supplement other control measures against HIV transmission. The only proviso would be an insistence on sterile procedures. The devastating impact of AIDS, especially in sub-Saharan Africa, necessitates a consideration of all possible interventions.

‘It would have control over me instead of me having control’: intrauterine devices and the meaning of reproductive freedom

In the past decade, enthusiasm for intrauterine devices (IUDs) has rapidly grown in the United States. Messages from health care providers, pharmaceutical advertisements, and public health campaigns extol the freedom that women can experience using a long-term, internal, highly effective contraceptive method. Little research has investigated how young women conceptualize IUDs in terms of freedom and control. We conducted a thematic analysis of in-depth, individual interviews with 37 young Black and Latina women and explored their perspectives on IUDs as promoting and constraining freedom. Participants with favorable views of the IUD (n = 13) appreciated that it would allow them to live their day-to-day lives ‘normally’ without thinking about contraception and with minimal side effects. Four current IUD users found the method empowering because they could pursue their goals without fear of unintended pregnancy. In contrast, nearly two-thirds of participants (n = 24) had predominantly negative views and focused on temporal and physical features of IUD use. They expressed concern that IUDs would impinge on their personal agency by restricting their bodily autonomy since they would not be able to discontinue use without a health care provider; found the idea of a contraceptive method inside their body for years unsettling; and/or desired flexibility over their pregnancy plans. These results highlight a contradiction between IUD promotion discourses and some women’s views about the method and their approaches to pregnancy. Discursive and clinical practices that encourage the use of long-acting contraceptive methods like IUDs over other methods may unintentionally infringe upon reproductive autonomy.     

Electrically-evoked control of the swinging leg after spinal cord injury: open-loop or motion sensor-assisted control?

In paraplegics, gait can be restored by means of functional electrical stimulation (FES). Because the electrophysiological responses of the lower limbs to the neuromuscular stimulus are not completely deterministic, several stimulation strategies have been reported in an attempt to refine stepping motion. In open-loop (OL) systems, the electrical stimulation sequences applied over the leg muscles are often tuned for each patient in order to improve the quality of gait. Our aim was to contrast this traditional technique against variable stimulation sequences based on motion sensors (MS) data feedback. Both strategies were tested over 240 stepping trials in three complete paraplegics. In comparison to OL, which used a customised stimulation sequence for each subject, the same MS strategy was as functional for all three subjects. Despite MS producing a lower variability on step lengths, the toe clearances had a similar pattern of variability regardless of the strategy applied. Although the novel MS showed promising results, the reliability of OL was also demonstrated. Therefore, we still recommend the use of OL mainly due to its faster donning and doffing, since this is a matter of importance for the user acceptance of any rehabilitation systems.     

Does locus of control moderate the effects of tailored health education materials?

Research in health communication has shown that individually tailored health education materials are more effective than traditional or generic materials in producing changes in health-related behaviors. However, tailored materials have not been equally effective for all individuals. Because locus of control affects behavioral outcomes in other self-change interventions, its effect on individuals' responses to tailored messages is of particular interest. The present study examined differences in cognitive responses to tailored and non-tailored weight loss materials among 198 overweight individuals. Weight locus of control significantly interacted with study group (who received either tailored or non-tailored materials), suggesting that externals may respond to tailored health education materials with counter-arguments. Implications for the development and application of tailored health communication materials are discussed.     

Tobacco control and the inequitable socio-economic distribution of smoking: smokers’ discourses and implications for tobacco control

Warning: this article contains strong language.

This paper focuses on the ways in which social context structures smokers’ views of, and reactions to, tobacco control. This exploratory study examined the interactions between tobacco control and smokers’ social contexts and how this may be contributing to inequalities in smoking. We found in our sample that higher socio-economic status (SES) smokers are more likely to positively respond and adapt to tobacco control messages and policies, viewing them for their future health betterment. Lower SES smokers in our study, on the other hand, are in conflict with tobacco control and feel intransigent with regard to the effects that tobacco control is having on their smoking. A better understanding of how social context structures people's perceptions of tobacco control may help us to understand why social inequalities in smoking are deepening, and potentially what can be done better in tobacco control to decrease them.     

Patterns of bias due to differential misclassification by case–control status in a case–control study

BACKGROUND: Case-control study is still one of the most commonly used study designs in epidemiological research. Misclassification of case-control status remains a significant issue because it will bias the results of a case-control study. There exist two types of misclassification, differential versus nondifferential. It is commonly accepted that nondifferential misclassification will bias the results of the study towards the null hypothesis. Conversely, no reports have assessed the impact and direction of differential misclassification on odds ratio (OR) estimate. The goal of the present study is to demonstrate by statistical derivation that patterns exist on the bias induced by differential misclassification. METHODS: Based on a 2 x 2 case-control study design, we derive the odds ratio without misclassification, and those with misclassification according to: (1) controls are misclassified as cases by exposure status; (2) cases are misclassified as controls by exposure status; and (3) both controls and cases are misclassified by exposure status simultaneously. Furthermore, mathematical derivations are shown for each of the ratios of the two odds ratios with and without misclassification. These methods are carried out by simulation analyses. RESULTS: Simulation analyses show that quite a number of biased odds ratios tend to move away from the null hypothesis and result in approaching zero or infinity with increasing proportion of misclassification among cases, controls, or both. These patterns are associated with the exposure status and the values of unbiased odds ratio (<1, 1, or >1). CONCLUSIONS: Our findings suggest that, unlike nondifferential misclassification, differential misclassification of case-control status in a case-control study may not weaken the exposure-outcome association towarding the null hypothesis. Care needs to be taken for interpreting the results of a case-control study when there exists differential misclassification bias, a practical issue in epidemiological research.     

Expanding the concept of parental control: a role for overt and covert control in children's snacking behaviour?

The existing literature on parental control and children's diets is confusing. The present paper reports two studies to explore an expanded conceptualisation of parental control with a focus on overt control which 'can be detected by the child' and covert control which 'cannot be detected by the child'. In study 1, 297 parents of children aged between 4 and 11 completed a measure of overt control and covert control alongside ratings of their child's snacking behaviour as a means to assess who uses either overt or covert control and how these aspects of parental control relate to a child's snacking behaviour. The results showed that lighter parents and those with children perceived as heavier were more likely to use covert control and those from a higher social class were more likely to use overt control. Further, whilst greater covert control predicted a decreased intake of unhealthy snacks, greater overt control predicted an increased intake of healthy snacks. In study 2, 61 parents completed the same measure of overt and covert control alongside the three control subscales of the Child Feeding Questionnaire [Birch, L.L., Fisher, J.O., Grimm-Thomas, Markey, C.N., Sawyer, R. (2001). Confirmatory factor analysis of the Child Feeding Questionnaire: A measure of parental attitudes, beliefs and practices about child feeding and obesity proneness. Appetite, 36, 201-210] to assess degrees of overlap between these measures. The results showed that although these five measures of control were all positively correlated, the correlations between the new and existing measures indicated a maximum of 21% shared variance suggesting that covert and overt control are conceptually and statistically separate from existing measures of control. To conclude, overt and covert control may be a useful expansion of existing ways to measure and conceptualise parental control. Further, these constructs may differentially relate to snacking behaviour which may help to explain some of the confusion in the literature.     

A Population-based Case–control Study of Isolated Anophthalmia and Microphthalmia

The purpose of the study was to reveal the etiological factors in the origin of isolated an/microphthalmia. The dataset of the Hungarian Case–Control Surveillance of Congenital Abnormalities, 1980–2002 containing 56 cases with isolated an/microphthalmia and 22,744 malformed controls with other non-ocular defects from the Hungarian Congenital Abnormality Registry, in addition of 56 matched control pairs and 37,837 population controls without defects from the National Birth Registry, was evaluated. Exposure data and family history were collected (i) prospectively by prenatal logbook and other medical records, (ii) retrospectively through a structured questionnaire filled-in by mothers, and (iii) information obtained by regional nurses at home visit of non-respondent mothers. The autosomal recessive origin of isolated an/microphthalmia was indicated in about 10% of cases on the basis of sib recurrence. Cases with isolated an/microphthalmia had a much shorter mean gestational age and smaller mean birth weight, a much larger proportion of preterm birth and low birthweight. Their mothers were younger with a predominance of first birth order, frequently unmarried with low socioeconomic status. These findings are in agreement with a much higher prevalence at birth of cases with isolated an/microphthalmia in the gypsy population probably due to the interaction of inbreeding effect and low socioeconomic status. Further molecular genetic studies are needed to identify gene mutations of isolated an/microphthalmia in the Hungarian gypsy population.     

Quality of anticoagulation control: do race and language matter?

No studies have evaluated the quality of anticoagulation control among populations characterized by low socioeconomic status, diverse racial and ethnic backgrounds, or limited English proficiency. We conducted a retrospective cohort study to evaluate the effects of race/ethnicity and language on anticoagulation outcomes among patients (N=864) receiving continuous anticoagulation services at a university-affiliated public hospital. White/non-Hispanic patients made up 24%, Asian/Pacific Islanders 33%, Hispanics 22%, African Americans 18%. English (63%), Spanish, (14%), and Cantonese (13%) were the most common languages. Mean time in therapeutic range (TTR) was 43%. After adjustment, TTR was lower for African Americans than for Whites (absolute difference, -8.7%, p< .001) and for Spanish-speaking than for English-speaking Hispanics (absolute difference, -7.2%, p< .05). There were no differences between Asian/Pacific Islanders and Whites, nor between Cantonese-speaking and English-speaking Asian/Pacific Islanders. Future research should examine mechanisms by which race/ethnicity and language affect quality of anticoagulation and evaluate programs to improve treatment in diverse communities.     

A nested case–control study of low birthweight among cosmetologists

Objective  

This study was designed to determine whether licensed female cosmetologists with a low birthweight child were more likely to perform specific occupational tasks during pregnancy than cosmetologists who had a normal weight child. We also investigated certain salon characteristics in relation to low birthweight status.     

Drug treatment and the control of malaria in Africa: a time of hope?

A wide selection of drugs is available to treat malaria. In many countries, however, the resistance of Plasmodium falciparum to drug therapy is problematic. For example, resistance to chloroquine is a problem in most tropical areas. Sulphadoxine/pyrimethamine, quinine, mefloquine, and artemisinin remain available and effective in many scenarios. Malarone and benflumetol/artemether are new drug combinations to apply against malaria infection. Each country needs an agreed-upon antimalarial drugs policy which takes into account the epidemiological factors affecting parasite distribution and the pattern of drug resistance. The prevailing health service characteristics, including the levels of health care at which different drugs are available, the risks and benefits of different drug regimens, compliance factors, and the logistics and cost of drug delivery must also be considered. Policy should be to reduce malaria mortality and morbidity and the development of drug resistance, while remaining within the limits of each country's budgetary and staffing capacity. Indications for treatment, genotyping and the reinfection problem in drug evaluation, amodiaquine reappraisal, new drug combinations, the role of drugs in preventing mosquito infection, and molecular biology in the surveillance of drug resistance are discussed.     

A case–control study of occupational exposures and systemic sclerosis

Objectives A case–control study was conducted in Verona, Italy, to assess the relationship between occupation, occupational exposures and systemic sclerosis (SSc).Methods Fifty-five cases (46 female and nine male) and 171 controls were recruited. Interviews provided work histories, including job titles, industry and likelihood of occupational exposure to silica, hand–arm vibration, organic solvents, and other chemicals. Odds ratios (ORs) and 95% confidence intervals (95% CI) were estimated.Results Female teachers (OR 3.4, 95% CI 1.2–10.1) and textile workers (OR 2.1, 95% CI 1.0–4.6) were at an increased risk of SSc. Compared with those never exposed, age-adjusted and gender-adjusted ORs were 2.3 (95% CI 1.0–5.4) among subjects exposed to organic solvents, 2.5 (95% CI 0.8–8.0) for exposure to selected chemicals, 1.7 (95% CI 0.4–7.6) for exposure to silica, and 1.5 (95% CI 0.5–4.8) for usage of vibrating tools. When data analysis was stratified according to gender, only men showed a significant increase in risk for exposure to solvents and selected chemicals.Conclusions The findings of this study tend to support the role of organic solvents and certain chemicals in SSc causation. The association with teaching and working in the textile industry suggests that other exposures are involved in the aetiology of SSc among women. However, because of the small number of subjects, particularly in stratified analyses, chance cannot be ruled out as an explanation of some findings of this study.     

How to control the costs of health care services – An inventory of strategic options

This paper has two objectives: (1) to provide an inventory of popular strategies for cost reduction or cost containment in the health services research literature and (2) to propose a coherent framework to organize this inventory. The purpose of this framework is to inform decision-makers when grappling with the opposing forces they face in choosing a cost reduction strategy. The trade-off is clear: to access progressively more possible strategies, the decision-maker must be ready to expose the population and patients to more significant changes in services provided. On one hand, more choices are preferable because each strategy attacks the problem from a different angle and being restricted to fewer “angles” increases the likelihood that a specific “well” may have dried up. On the other hand, we know that change is often viewed, a priori, negatively in health care management, so there are pressures to limit the impact on services.
