Potential influence of Type A personality on plasma C-reactive protein levels in people with diabetes.

AIM: Type A personality, although classically known as a factor linked to increased vascular risk, has recently been associated with increased survival in patients with diabetes. As low-grade inflammation predicts a poor outcome, the present study explored the potential associations between Type A and plasma levels of C-reactive protein (CRP) in diabetes. METHODS: Type A personality was assessed by the Bortner questionnaire in people with diabetes. The association between Type A and plasma CRP levels was examined by multivariable linear regression, and structural equation modelling (SEM) was performed to determine the impact of the major clinical, biological and psychological confounders. RESULTS: The study included 626 participants with type 1 and type 2 diabetes from the Diabetes and Psychological Profile study. Multivariable analyses showed an independent inverse association between Type A score and CRP levels. The structural model adjusted for age, gender, diabetes type and duration, body mass index (BMI), smoking status, alcohol abuse, oral antidiabetic and statin treatments, HbA1c levels, lipids, perceived stress, anxiety and depression revealed significant associations between CRP and Type A (ß=-0.135, 95% CI: -0.242, -0.028; P=0.014), BMI (ß=0.194, 95% CI: 0.038, 0.350; P=0.015) and HDL cholesterol (ß=-0.132, 95% CI: -0.245, -0.020; P=0.014). CONCLUSION: Our present study data indicate that Type A personality is independently associated with lower CRP levels. This lower level of inflammation might explain the better clinical outcomes associated with Type A personality in patients with diabetes.

Are elderly patients with diabetes being overtreated in French long-term-care homes?

AIM: In France, diabetes prevalence and ageing of the population are both on the increase, yet little information on diabetes in elderly patients living in geriatric institutions is available. Moreover, institutionalized diabetic patients are not included in the French recommendations for the management of diabetes in the elderly. For this reason, the aim of the present study was to evaluate diabetes management in older, institutionalized patients. METHODS: The medical records of 100 diabetic patients, aged 65 years and over, and living in seven geriatric institutions in the Côte d'Or region of France, were studied from May 2008 to January 2009. RESULTS: Prevalence of diabetes in these seven geriatric institutions was 15.46±4.9%, higher than in the general population. The diabetic patients had a mean age of 81.85±11.93 years, and 32% had glycated haemoglobin (HbA(1c)) less or equal to 6.5%, indicating a high risk of severe hypoglycaemia. A diet for diabetes was prescribed in 54% of the patients, but HbA(1c) levels did not differ between patients following and not following the diet (7.26±1.36% vs 7.11±1.10%, respectively; P=0.27). Creatinine was assessed in 87% of the patients, and 16% were ophthalmologically followed-up. Daily capillary blood glucose monitoring was performed in 100% of the patients taking insulin and in 17% of those taking oral antidiabetic treatment (P<0.0001). CONCLUSION: Our data show that, among older institutionalized patients, the prevalence of diabetes is high and the control of diabetes too tight, with a potential risk of hypoglycaemia. Antidiabetic treatment should be reduced when the HbA(1c) value is less than 7.5% in this frail and functionally dependent population. Furthermore, a diabetic diet, prescribed for more than half this population, is useless for glycaemic control and may even impinge on quality of life.

Effect of insulin treatment on plasma oxidized LDL/LDL-cholesterol ratio in type 2 diabetic patients.

OBJECTIVE: In type 2 diabetes mellitus, oxidized LDL/LDL-Cholesterol ratio, an accurate estimation of in vivo LDL oxidation, has been reported elevated and associated with macrovascular disease. Because insulin therapy induces significant modification of lipid metabolism, in type 2 diabetes, we evaluated the effect of insulin treatment on oxidized LDL/LDL-C ratio in type 2 diabetic patients and analyzed the results in comparison with the modifications induced by insulin on glycaemia, plasma lipids and LDL receptors. RESEARCH DESIGN AND METHODS: Plasma oxidized LDL concentrations were measured by sandwich ELISA in 21 type 2 diabetic patients before and 3 months after the introduction of insulin therapy, and in 27 age-matched controls. RESULTS: Type 2 diabetic patients had, compared to controls, significantly increased oxidized LDL/LDL-C ratio (P<0.0001). Three months after insulin treatment, oxidized LDL/LDL-C ratio was significantly reduced (21.1+/-4.7 vs. 24.0+/-5.8 U/mmol, P<0.01). This reduction was strongly associated, in multivariate analysis, with reduction of LDL(TG/cholesterol ratio) (P=0.008), and to a lesser extent with the decrease of LDL fructosamine (P=0.034), but not with the increase of the number of LDL receptors. CONCLUSIONS: In the present study we demonstrate for the first time a lowering effect of insulin therapy on oxidized LDL/LDL-C ratio in type 2 diabetic patients. This decrease is mainly associated with the reduction of LDL TG-enrichment, and to a lesser extent with the decrease of LDL glycation, but not with the insulin-induced increase in number of LDL receptors.

Successful aging.

OBJECTIVE: Until now, prospective studies of aging have begun with 50-60-year-olds, not adolescents. Premature death, childhood variables, and alcohol abuse have been often ignored, as has successful aging. METHOD: The authors reviewed the existing literature on health in late life in order to highlight that, increasingly, successful aging is not an oxymoron. The present study followed two cohorts of adolescent boys (237 college students and 332 core-city youth) for 60 years or until death. Complete physical examinations were obtained every 5 years and psychosocial data every 2 years. Predictor variables assessed before age 50 included six variables reflecting uncontrollable factors: parental social class, family cohesion, major depression, ancestral longevity, childhood temperament, and physical health at age 50 and seven variables reflecting (at least some) personal control: alcohol abuse, smoking, marital stability, exercise, body mass index, coping mechanisms, and education. The six outcome variables chosen to assess successful aging at age 70-80 included four objectively assessed variables (physical health, death and disability before age 80, social supports, and mental health) and two self-rated variables (instrumental activities of daily living and life enjoyment). RESULTS: Multivariate analysis suggested that "good" and "bad" aging from age 70-80 could be predicted by variables assessed before age 50. More hopeful still, if the seven variables under some personal control were controlled, depression was the only uncontrollable predictor variable that affected the quality of subjective and objective aging. CONCLUSIONS: One may have greater personal control over one's biopsychosocial health after retirement than previously recognized.

Management of diabetes in French prisons: a cross-sectional study.

AIMS: To assess by a survey the management of prisoners with diabetes treated with insulin in French prisons. METHODS: A questionnaire was sent to the head of healthcare services for prisoners of every French prison. Information was obtained on prevalence of insulin-treated diabetes prisoners and diabetes care in prison. The number of episides of ketoacidosis and hypoglycaemia needing hospital admissions were evaluated during the past year. RESULTS: Among the 163 questionnaires sent, 115 were returned, giving an overall response rate of 69%. At the time of the study the prison population was 38 175 people. One hundred and sixty-nine prisoners were treated by insulin (0.4%). Self-monitoring of blood glucose was available only for 94 (55.6%) insulin-treated prisoners. A total of 130 (76.9%) prisoners performed two insulin injections daily or less, 105 (62.1%) prisoners were not allowed to keep their insulin delivery systems with them. Of the prisoners who treated themselves, 14 (12.1%) used syringes and 42 (36.5%) used pen devices. Ninety-two (55.1%) prisoners had had access to a diabetes specialist during the previous year. Diabetic diets were available in only 65 (60.7%) prisons. From June 1998 to June 1999, there were 20 hospital admissions for a diabetic ketoacidosis and 14 for hypoglycaemia. CONCLUSIONS: This study shows that prison decreases the autonomy of diabetic prisoners who often cannot self-inject or test their blood. Access to visiting consultant diabetologists and specialist nurses to educate both prisoners with diabetes and prison staff could improve diabetic care.

Healthy aging among inner-city men.

OBJECTIVE: Until now, prospective studies of aging have begun with 50- to 60-year olds, not adolescents. Premature deaths, childhood variables, and alcohol abuse have been often ignored. So has positive aging. As people live longer, gerontology needs to understand the determinants of health as well as illness in the later years. METHOD: The present study follows a cohort of adolescent boys (332 inner-city youths) for 60 years or until death. Complete physical exams were obtained every 5 years and psychosocial data every 2 years. Predictor variables assessed prior to age 50 include six variables reflecting uncontrollable factors--parental social class, environmental strengths, number of family problems, major depression, ancestral longevity, and premorbid physical health at age 50--and six variables reflecting (at least some) personal control: alcohol abuse, smoking, marital stability, body mass index, coping mechanisms, and education. The four outcome variables chosen to assess healthy aging at 70 reflected both "mind" and "body." They included objectively assessed variables (death and/or disability prior to 70, and objective mental health) and two subjectively assessed variables (perceived instrumental activities of daily living and life enjoyment). RESULTS: Multivariate analysis suggested that positive aging at 70 could be predicted by variables assessed prior to age 50. More hopeful still, if the six variables under some personal control were controlled, depression was the only uncontrollable variable that affected the quality of subjective and objective aging. CONCLUSIONS: First, we may have greater personal control over our biopsychosocial health after retirement than previously recognized. Second, in this cohort, psychiatric rather than sociological predictors appeared more important.

[Treatment of parathyroid adenomas with ethanol injection under ultrasonographic guidance]. / Traitement des adénomes parathyroïdiens par alcoolisation sous contrôle échographique.

STUDY OBJECTIVE: The objective of this retrospective study was to report the results of ethanol injection in parathyroid adenomas. PATIENTS AND METHOD: Since 1988, 31 patients with inoperable primary hyperthyroidism have been treated by ultrasound-guided percutaneous ethanol injection into the adenoma. The main surgical contraindications were heart failure (n = 12) and age over 85 years (n = 11). Plasma calcium and PTH were measured 48 hours after ethanol injection and during subsequent follow-up. RESULTS: Patients had one to three ethanol injections. With a mean 5-year follow-up, total success with normal plasma calcium and PTH levels was achieved in 20 patients (64.5%), 4 of whom underwent another ethanol injection after 1 to 3 years. Partial success with correction of plasma calcium only was achieved in 9 patients (29%) resulting in an obvious clinical benefit. Failure was observed in 2 patients (6.5%) with nodular goiter, probably due to incorrect localization of the adenoma. Treatment was always well tolerated and no major side effect was observed. CONCLUSION: Ultrasound-guided percutaneous ethanol injection of parathyroid adenoma is effective in most cases of hyperparathyroidism and very useful in patients with a high surgical risk. The need for precise ultrasound localization of the adenoma is the main limitation of this treatment.

Social/emotional intelligence and midlife resilience in schoolboys with low tested intelligence.

Seventy-three inner-city boys with a mean IQ of 80 were followed prospectively from age 14 until age 65. Their adult adjustment was compared to a socioeconomically matched sample of 38 boys with a mean IQ of 115. Although childhood social disadvantage did not distinguish the groups with low and high IQs, half of the low-IQ men enjoyed incomes as high and had children as well-educated as did the high IQ men. These resilient low-IQ men were more likely to be generative, to use mature defenses, and to enjoy warm object relations than the high IQ group as a whole.

Delinquency and mortality: A 50-year follow-up study of 1,000 delinquent and nondelinquent boys.

OBJECTIVE: It is well established that until age 40 years, delinquent individuals have roughly twice the mortality of nondelinquent individuals and that the excess deaths are largely due to accidents, violence, and substance abuse. The present study examined if the increased mortality of delinquent subjects continues until age 65 years and, if so, why. METHOD: The authors followed 475 delinquent and 456 matched nondelinquent comparison boys from age 14 years until age 65 years. RESULTS: Thirteen percent (N=62) of the delinquent and only 6% (N=28) of the nondelinquent subjects died unnatural deaths. By age 65 years, 29% (N=139) of the delinquent and 21% (N=95) of the nondelinquent subjects had died from natural causes. In a univariate analysis, frequency of delinquency, abuse of alcohol, adult crime, dysfunctional home environment, and poor education were significantly related to death, especially to unnatural death. However, when delinquency and alcohol abuse were controlled by logistic regression, education, dysfunctional upbringing, and adult criminality made no further contributions to mortality. CONCLUSIONS: Although delinquency is strongly associated with premature mortality, the etiological links remain unclear. Alcohol abuse and poor self-care in adulthood (e.g., infections or accidents) account for most of the modest variance in mortality that could be accounted for.

Adaptive mental mechanisms. Their role in a positive psychology.

Psychology needs a metric for positive mental health that would be analogous to the IQ tests that measure above-average intelligence. The Defensive Function Scale of the DSM-IV offers a possible metric. In the present article the author links the transformational qualities of defenses at the mature end of the Defensive Function Scale--altruism, suppression, humor, anticipation, and sublimation--to positive psychology. First, the methodological problems involved in the reliable assessment of defenses are acknowledged. Next, the use of prospective longitudinal study to overcome such difficulties and to provide more reliable definition and measurement of defenses is outlined. Evidence is also offered that, unlike many psychological measures, the maturity of defenses is quite independent of social class, education, and IQ. Last, evidence is offered to illustrate the validity of mature defenses and their contribution to positive psychology.

A systematic review of the mortality of depression.

OBJECTIVE: The literature on the mortality of depression was assessed with respect to five issues: 1) strength of evidence for increased mortality, 2) controlling for mediating factors, 3) the contribution of suicide, 4) variation across sample types, and 5) possible mechanisms. METHOD: All relevant English language databases from 1966 to 1996 were searched for reviews and studies that included 1) a formal assessment of depressive symptoms or disorders, 2) death rates or risks, and 3) an appropriate comparison group. RESULTS: There were 57 studies found; 29 (51%) were positive, 13 (23%) negative, and 15 (26%) mixed. Twenty-one studies (37%) ranked among the better studies on the strength of evidence scale used in this study, but there are too few comparable, well-controlled studies to provide a sound estimate of the mortality risk associated with depression. Only six studies controlled for more than one of the four major mediating factors. Suicide accounted for less than 20% of the deaths in psychiatric samples, and less than 1% in medical and community samples. Depression seems to increase the risk of death by cardiovascular disease, especially in men, but depression does not seem to increase the risk of death by cancer. Variability in methods prevents a more rigorous meta-analysis of risk. CONCLUSION: The studies linking depression to early death are poorly controlled, but they suggest that depression substantially increases the risk of death, especially death by unnatural causes and cardiovascular disease. Future well-controlled studies of high risk groups may guide efforts to develop treatments that reduce the mortality risk of depression.

HCV infection and diabetes mellitus: influence of the use of finger stick devices on nosocomial transmission.

An increased prevalence of hepatitis C virus (HCV) infection in patients with diabetes mellitus has suggested a link between these two conditions and the possibility of patient-to-patient HCV transmission during hospital admissions in diabetes units. We investigated the prevalence of HCV antibodies in 259 patients with diabetes mellitus consecutively admitted to our diabetic unit in 1998. The control group was composed of 14,100 volunteer blood donors. We divided the diabetic patients into two groups according to their HCV antibody status and also analysed patients for the following variables: age, disease duration, diabetes treatment, previous hospital admissions in a diabetes unit and use of finger stick devices. Anti-HCV antibodies were detected in 8 diabetic patients and 6 blood donors (3.09% vs 0.04%, p < 0.001). No differences were observed between anti-HCV-positive and anti-HCV-negative diabetic patients in terms of mode of treatment, previous hospital admissions in a diabetic unit and use of finger stick devices for capillary blood sampling. Our findings indicate that these medical practices play no role in nosocomial transmission of HCV in diabetic patients.

[Dermoid cyst of the ovary. False positive diagnosis in iodine 131 scintigraphy of differentiated thyroid cancers]. / Kyste dermoïde de l'ovaire. Faux positif à reconnaître lors de la surveillance scintigraphique à l'iode 131 des cancers différenciés thyroïdiens.

BACKGROUND: Total body 131-iodine labeled scintiscan is used to screen for residual tumoral tissue after ablation of differentiated thyroid carcinoma. At therapeutic doses, radioactive iodine can also be used for treatment. Thyroglobulin level, usually undetectable a few months after total thyroidectomy and metabolic irradiation with 131-iodine in patients without initial metastases, is absolutely necessary for interpreting the scintiscans. Iodine uptake occur in dermoid cysts which usually contain thyroid tissue. CASE REPORT: A 44-year old woman underwent total thyroidectomy with node dissection for papillary carcinoma of the thyroid with a vesicular architecture. Four months later, the total body 131-iodine scintiscan demonstrated a round zone of uptake in the pelvic area. The lesion was found to be a typical dermoid cyst. No thyroid or tumoral tissue could be demonstrated. DISCUSSION: Dermoid cysts can be the cause of false positive 131-scintiscans in patients followed after resection of differentiated thyroid carcinoma. Unlike previously reported cases, the dermoid cyst in this patient was totally devoid of thyroid tissue.

Are social supports in late midlife a cause or a result of successful physical ageing?

BACKGROUND: Many studies have noted a strong association between poor social support and premature mortality. A limitation of such studies has been their failure to control adequately for confounders that damage both social supports and physical health. METHODS: A 50-year prospective multivariate study of 223 men was used to examine the possible causal relationships between social supports and health. Alcohol abuse, prior physical health and mental illness prior to age 50 were controlled. Relative social supports were quantified over the period from age 50 to 70. RESULTS: Adequacy of social supports from age 50 to 70 was powerfully correlated with physical health at age 70 (P < 0.001). However, such social supports were also powerfully predicted by alcohol abuse (P < 0.001), smoking (P < 0.001) and indicators of major depressive disorder (P < 0.01) assessed at age 50. When prior smoking, depression and alcohol abuse were controlled, then the association of physical health with social supports was very much attenuated. Some facets of social support like religion and confidantes were unassociated with health even at a univariate level. Surprisingly, in this sample friends seemed more important for sustained physical health than closeness to spouse and to children. CONCLUSIONS: While social supports undoubtedly play a significant role in maintaining physical well-being in late life, much of the association between poor social supports and mortality may be mediated by alcoholism, smoking and pre-morbid psychopathology.
