Immunosuppression with azathioprine and prednisone in recent-onset insulin-dependent diabetes mellitus.

We randomly assigned 46 patients (mean age, 11.7 years; range, 4.5 to 32.8) with newly diagnosed insulin-dependent diabetes mellitus within two weeks of beginning insulin to receive either corticosteroids for 10 weeks plus daily azathioprine for one year or no immunosuppressive therapy. Half the 20 immunosuppressed patients completing the one-year trial had satisfactory metabolic outcomes (hemoglobin A1c less than 6.8 percent; stimulated peak C peptide greater than 0.5 nmol per liter; insulin dose less than 0.4 U per kilogram of body weight per day) as compared with only 15 percent of the controls. Three of 20 immunosuppressed patients, but no controls, were insulin independent at one year. Two of these continue to receive azathioprine without insulin after more than 27 months of follow-up. The response to immunosuppression correlated with older age, better initial metabolic status, and lymphopenia (less than 1800 lymphocytes per cubic millimeter) resulting from immunosuppression. The side effects of azathioprine included vomiting in one patient and mild hair loss in several others. Prednisone use resulted in a transient cushingoid appearance, weight gain, and hyperglycemia. The growth rate remained normal in all patients. We conclude that early immunosuppression with short-term use of corticosteroids plus daily azathioprine can improve metabolic control in some patients with insulin-dependent diabetes mellitus, but results from this unblinded study are preliminary and require further confirmation and long-term follow-up.

Methodological Issues in Diabetes Research: Measuring adherence

The prevalence of nonadherence in IDDM and NIDDM populations and conceptual and methodological issues relevant to measuring diabetes regimen adherence are reviewed. The prevalence of nonadherence varies across the different components of the diabetes regimen, during the course of the disease, and across the patients life span. Although prevalence rates might be expected to differ between IDDM and NIDDM populations, this rarely has been evaluated. Conceptual problems in defining and measuring adherence include: the absence of explicit adherence standards against which the patients behavior can be compared; inadvertent noncompliance attributable to patient-provider miscommunication and patient knowledge/skill deficits; the behavioral complexity of the diabetes regimen; and the confounding of compliance with diabetes control. Methods for measuring adherence include: health status indicators, provider ratings, behavioral observations, permanent products, and patient self-reports, including behavior ratings, diaries, and 24-h recall interviews. A measurement method should be selected on the basis of reliability, validity, nonreactivity, sensitivity to the complexity of diabetes regimen behaviors, and measurement independence from the patients health status. The timing of measurements should be based on the stability of adherence behaviors and temporal congruity with other measures of interest (e.g., indexes of metabolic control). Directions for future research and suggestions for clinical practice are provided.

Psychosocial factors in juvenile diabetes: a review.

Studies assessing (1) the influence of psychosocial factors on the onset of juvenile diabetes, (2) the influence of psychosocial factors on the course of this disease, and (3) the influence of diabetes on the psychosocial development of the child are reviewed. Directions for future research are suggested.

Psychological response to prenatal genetic counseling and amniocentesis.

The purpose of the present study was to characterize the psychological status (attitudes toward selective abortion, perceived risk, comprehension, patient satisfaction, coping, and state anxiety) of pregnant women at increased risk for fetal genetic anomalies who were referred for prenatal genetic counseling and amniocentesis; to determine which of these factors would predict amniocentesis use; and to identify patient outcomes associated with counseling and testing. Participants were 129 women aged 18 years and older who had one or more fetal genetic risk factors. All were recruited from an urban womens health clinic. The results revealed elevated perceptions of risk and moderate state anxiety despite adequate comprehension of, and patient satisfaction with, the process and content of genetic counseling. Approximately 78% agreed to testing; those who consented were more likely to hold favorable attitudes toward abortion than those who refused. Post-counseling, women experienced decrease in their perceived risk of having a baby born with a birth defect although perceived risk estimates remained higher than actual risks. Anxiety was clinically elevated and highest at the pre-counseling stage, though it dissipated to normal levels over time. Previous experience with prenatal diagnostic testing, increased perceived risk of a birth anomaly, and favorable attitudes toward abortion were independently associated with increased pre-counseling anxiety. Women who were more anxious pre-counseling remained more anxious post-counseling. Coping (high versus low monitoring) was unrelated to anxiety. These findings suggest that women who participate in prenatal counseling and testing may be subject to experience distress and unrealistic perceptions of their risk and may benefit from interventions designed to lessen these states.

Competencies for psychology practice in primary care.

This article reports on the outcome of a presidential initiative of 2012 American Psychological Association President Suzanne Bennett Johnson to delineate competencies for primary care (PC) psychology in six broad domains: science, systems, professionalism, relationships, application, and education. Essential knowledge, skills, and attitudes are described for each PC psychology competency. Two behavioral examples are provided to illustrate each competency. Clinical vignettes demonstrate the competencies in action. Delineation of these competencies is intended to inform education, practice, and research in PC psychology and efforts to further develop team-based competencies in PC.

Assessing daily management of childhood diabetes using 24-hour recall interviews: reliability and stability.

Conducted 24-hr recall interviews concerning daily diabetes management with seventy-eight 6- to 19-year-old patients and their parents. Patients and parents were interviewed independently nine times over 3 months. Data obtained were used to construct 13 adherence measures. All measures yielded statistically significant estimates of parent-child concordance. Parent-child agreement was higher for weekday versus weekend behaviors and when based on nine versus three interviews. For the sample as a whole, parent-child concordance remained stable over the course of the study. Compared to the older patients, the 6- to 9-year-olds exhibited poorer parent-child agreement on measures involving time (e.g., injection and exercise-duration measures). This deficit disappeared, however, as the children became more practiced with the interview procedure. The dietary and glucose-testing measures exhibited moderate stability over the 3-month study. Lower stability estimates were obtained for the exercise and injection measures.

Behavioral interventions for childhood nocturnal enuresis: the differential effect of bladder capacity on treatment progress and outcome.

Study participants were fifty 5- to 13-year-old children (33 boys and 17 girls) with nocturnal enuresis of at least 3 months duration. All wet their beds at least twice per week, were of normal intelligence, and were without demonstrable organic cause for their enuresis. Each youngsters pretreatment maximum functional bladder capacity (MFBC) was used to classify the child as having small or large MFBC based on available norms. Youngsters were then randomly assigned to treatment with the urine alarm (UA) alone or with the urine alarm supplemented with retention control training (UA plus RCT). Of the 40 youngsters who completed treatment, 37 (92.5%) achieved the treatment goal of 14 consecutive dry nights. Two additional children became dry during follow-up, leaving only one child who failed to stop wetting. Sixteen children (41%) subsequently relapsed, but all who reentered treatment became dry. Because treatment outcome was uniformly excellent across all groups, treatment progress was evaluated by analyzing wetting frequency and arising at night to use the bathroom during treatment, as well as prechange and postchange in MFBC For both wetting frequency and arising at night, there was a significant interaction between bladder capacity and treatment. Small MFBC children treated with the UA plus RCT and large MFBC youngsters treated with the UA alone had the fewest wetting episodes and got up at night to use the bathroom less often; these youngsters took less time to be successfully treated. Prechanges and postchanges in MFBC indicated that RCT did not lead to consistent increases in bladder capacity in the sample studies. The 10 children who terminated treatment prematurely had lower self-esteem and more parent-reported conduct problems than the 40 children who completed treatment.

The effects of a peer-modeling film on children learning to self-inject insulin

This study investigated the effects of a peer-modeling film on anxiety reduction and skill acquisition in children learning to self-inject insulin. Twenty-eight insulin-dependent children, aged 6–9 years and attending a summer camp for youngsters with diabetes, were randomly assigned to view a peer-modeling film of children learning self-injection or another film addressing nutrition. Immediately after viewing the film, the children were taught to self-inject insulin. Physiological, self-report, and observational measures were obtained at several points during the experiment and at a follow-up, 4 days later. There was little evidence indicating that the children were anxious, preventing assessment of the films utility in anxiety reduction. On the other hand, the oldest girls viewing the peer-modeling film showed greater skill in self-injection than their counterparts viewing the nutrition film. The importance of age, sex, and previous experience as variables potentially affecting a modeling films utility was discussed.

Prospective assessment in newborns of diabetes autoimmunity (PANDA): Maternal understanding of infant diabetes risk

Purpose: To assess accuracy of mothers’ understanding of their newborns’ genetic risk for type 1 diabetes and to identify predictors of the comprehension and retention of genetic information. Methods: Mothers of 435 newborns genetically screened at birth were informed of the infant’s risk for type 1 diabetes using a standard script that provided both categorical and numerical risk information. The mothers’ comprehension and retention of this information were assessed by structured interview on two occasions, ∼3.6 weeks and ∼3.9 months postnotification. Results: At the initial interview, 73.1% of mothers gave a correct estimate of their child’s genetic risk, 3.2% overestimated risk, 13.3% underestimated risk, and 10.3% could not recall risk at all. At the follow-up interview, fewer mothers (61.9%) correctly estimated their child’s risk and more mothers (24.4%) underestimated their child’s risk. Maternal accuracy was associated with maternal education, ethnic minority status, infant risk status, maternal ability to spontaneously recall both categorical and numerical risk estimates, and length of time since risk notification. Underestimation of risk was associated with maternal education, family history of diabetes, time since risk notification, and maternal anxiety about the baby’s risk. Conclusion: The accuracy of mothers’ recall of infant risk declines over time, with an increasing number of mothers underestimating the infant’s risk. Effective risk communication strategies need to be developed and incorporated into genetic screening programs.

The Assessment and Treatment of Children’s Fears

While fear is a necessary and often “healthy” response to a wide variety of situations, at times it can become so debilitating as to be maladaptive. Careful distinctions involving terms such as fear, phobia, and anxiety are not always made. However, there seems to be some general consensus that fear connotes a differentiated response to a specific object or situation. Anxiety is a more diffuse, less focused response, perhaps best described as apprehension without apparent cause. A phobia is a special form of fear that (1) is out of proportion to the demands of the situation, (2) cannot be explained or reasoned away, (3) is beyond voluntary control, and (4) leads to avoidance of the feared situation (Marks, 1969).
