RESUMO

OBJECTIVE: With the current aging of the world's population, primary hyperparathyroidism (PHPT) is increasingly detected in the elderly. Yet data on the presentation and outcome of PHPT in this group are scarce. The objective was to describe a cohort of patients aged 75 years or more with PHPT observed in our endocrine clinic. STUDY DESIGN: A retrospective analysis of medical records in an endocrine clinic at a tertiary hospital. We evaluated 182 patients with PHPT, aged 75 years or more at their last follow-up, all diagnosed at age 65 or more. Laboratory data were compared at diagnosis and last follow-up. RESULTS: Mean age at diagnosis was 73 ± 4 years, last follow-up was at 83 ± 4 years, and mean follow-up was 11.3 ± 5.5 years. Osteoporosis, fractures, and nephrolithiasis were diagnosed in 114(63 %), 84(46 %), and 43(24 %) patients, respectively. Overall, 150 patients had an indication for surgery; of them, the 29 who underwent parathyroidectomy were younger than the non-operated patients and had higher rates of hypercalciuria. During the follow-up of the 141 patients who did not undergo operation, serum and urinary calcium levels significantly had decreased, and vitamin D level had increased at last visit (10.4 ± 0.5 mg/dl, 161 ± 70 mg/24 h, 69 ± 17 nmol/l, p < 0.01 respectively) compared with levels at diagnosis (10.6 ± 0.2 mg/dl, 223 ± 95 mg/24 h, 53 ± 15 nmol/l, respectively, p = 0.001). Overall, 38 of the 182 patients (20 %) died during follow-up; these patients were significantly older at diagnosis (76 ± 5 vs. 72 ± 4 years) but there were no differences in laboratory variables. CONCLUSIONS: While most patients had a formal indication for surgery, few underwent parathyroidectomy. Serum and urinary calcium significantly decreased during follow-up in patients who did not undergo surgery. Our data are reassuring and support at least the consideration of conservative treatment for these patients.

RESUMO

OBJECTIVES: Abnormal activation of toll-like receptors (TLRs) is observed in obese rodents and is correlated with local dysbiosis and increased gut permeability. These purported changes trigger systemic inflammation associated with obesity-related comorbidities, including type 2 diabetes (T2D). Roux-en-Y gastric bypass (RYGB) surgery is an effective treatment for severe obesity and known to induce changes in the gut microbiota and decrease systemic inflammation in humans. This study examined the intestinal expression of TLR-encoding genes in obese women (n = 20) treated with RYGB surgery and the relationship of these genes with T2D remission (T2Dr METHODS: Intestinal biopsies were performed before and 3 months after RYGB surgery. Partial and complete T2Dr after 1 year was assessed using the American Diabetes Association criteria. Affymetrix Human GeneChip 1.0 ST array (microarray) and TaqMan assay (real-time quantitative polymerase chain reaction) were used to analyze intestinal gene expression, and associations with systemic markers of energy homeostasis were examined. RESULTS: Patients experienced significant weight loss (P < 0.001) and altered gut TLR gene expression 3 months after surgery. The main effects were a reduction in jejunal TLR4 expression in patients with complete and partial T2Dr (P < 0.05). There was a postoperative decrease in jejunal TLR7 expression in patients with complete T2Dr that correlated inversely with high-density lipoprotein cholesterol and positively with triglyceride concentrations, but not with weight loss. CONCLUSIONS: RYGB-induced weight loss-independent changes in the expression of intestinal TLR-encoding genes in obese women and complete T2Dr that was correlated with systemic markers of energy homeostasis. The modulation of intestinal TLRs may mediate inflammatory mechanisms linked to T2Dr after RYGB surgery.

RESUMO

OBJECTIVE: To assess treatment satisfaction and the effectiveness of a flash glucose monitoring (FGM) system in patients with type 2 diabetes using insulin. RESEARCH DESIGN AND METHODS: A total of 101 patients with type 2 diabetes on multiple daily insulin injections (MDI) for at least 1 year were assigned randomly to the FGM intervention (n = 53) or the standard care (control) group (n = 48) and followed for 10 weeks. Both groups were instructed to adjust their insulin doses in face-to-face and telephone visits. Satisfaction with treatment, quality of life, comfort using FGM, HbA1c, and frequency of hypoglycemic events were evaluated. RESULTS: The intervention group found treatment significantly more flexible (P = 0.019) and would recommend it to their counterparts (P = 0.023). Satisfaction using the FGM system was high. The changes in HbA1c were -0.82% (9 mmol/mol) vs. -0.33% (3.6 mmol/mol) in the intervention and control group, respectively (P = 0.005); in nonprespecified post hoc analysis, 68.6% of the patients in the intervention group had their HbA1c reduced by ≥0.5% (5.5 mmol/mol) compared with 30.2% in the control group (P < 0.001), and 39.2% had their HbA1c reduced by ≥1.0% (10.9 mmol/mol) vs. 18.6% in the control group (P = 0.0023) without an increased frequency of hypoglycemia. CONCLUSIONS: FGM tends to improve treatment satisfaction and may lead to amelioration of glycemic control in patients with type 2 diabetes on MDI without increasing the frequency of hypoglycemia.

RESUMO

INTRODUCTION: Fish oil-based nutrition is protective in severe critical care conditions. Regulation of the activity of transcription factor NF-kappaB is an important therapeutic effect of the major omega-3 fatty acids in fish oil, eicosapentaenoic and docosahexaenoic acid (EPA and DHA). METHODS AND RESULTS: Using the articles obtained by a Pubmed research, this article reviews three aspects of NF-kappaB/inflammatory inhibition by fish oil. (1) Inhibition of the NF-kappaB pathway at several subsequent steps: extracellular, free omega-3 inhibits the activation of the Toll-like receptor 4 by endotoxin and free saturated fatty acids. In addition, EPA/DHA blocks the signaling cascade between Toll-like/cytokine receptors and the activator of NF-kappaB, IKK. Oxidized omega-3 also interferes with the initiation of transcription by NF-kappaB. (2) The altered profile of lipid mediators generated during inflammation, with production of the newly identified, DHA-derived inflammation-resolving mediator classes (in addition to the formation of less pro-inflammatory eicosanoids from EPA). Resolvin D1 and Protectin D1 are potent, endogenous, DHA-derived lipid mediators that attenuate neutrophil migration and tissue injury in peritonitis and ischemia-reperfusion injury. Their production is increased in the later stages of an inflammatory response, at which time they enhance the removal of neutrophils. (3) Modulation of vagal tone with potential anti-inflammatory effects: vagal fibers innervating the viscera down-regulate inflammation by activating nicotinic receptors upon infiltrating and resident macrophages. Stimulation of the efferent vagus is therapeutic in experimental septic shock. Fish oil supplementation increases vagal tone following myocardial infarction and in experimental human endotoxinemia. CONCLUSION: It remains to be shown whether these pleiotropic actions of EPA/DHA contribute to fish oil's therapeutic effect in sepsis.

RESUMO

AIMS: To explore the feasibility and noninferiority of group care in a diabetes outpatient clinic in comparison with individual care. METHODS: In this prospective, randomized, nonblinded, one center (university hospital) trial, 60 patients (28 with type 1 and 32 with type 2 diabetes) with a mean duration of diabetes of 22.5 ± 11.7 years were randomly assigned to group (6 patients per group) or individual care for one year. The primary endpoints were the change in HbA1c and visits to outpatient clinics. The secondary endpoints were changes in body mass index, blood pressure levels, waist circumference, non-HDL cholesterol, diabetes-related and well-being index questionnaires, and the number of hospitalizations. RESULTS: Group care was not inferior to individual care for any of the above parameters except for the number of visits to a primary care physician. CONCLUSION: Group care is feasible in a diabetes clinic and is as effective as individual care. Implementation of group care may facilitate access to specialized care to a larger population of patients with diabetes type 1 and 2.

RESUMO

BACKGROUND: Mechanisms of type 2 diabetes remission (T2Dr) after Roux-en-Y gastric bypass (RYGB) in obese patients appear to involve gastrointestinal hormones. OBJECTIVE: The objective of this study is to explore changes in ghrelin plasma levels and ghrelin gastrointestinal gene expression (GHRL) after RYGB, and their relationships to T2Dr. SETTING: In 20 obese women with T2D, before and 3 months after RYGB, we assessed GHRL expression by microarray and quantitative RT-PCR in gastrointestinal biopsy samples and plasma levels of ghrelin. RESULTS: After RYGB, GHRL expression increased in the excluded stomach (p < 0.05) with no change in other gastrointestinal sites. There were no significant changes in ghrelin plasma levels and no correlations with T2Dr. CONCLUSIONS: After RYGB, over-expression of GHRL gene occurs only in the excluded stomach with no correlation to T2Dr.

RESUMO

OBJECTIVES: Patients with advanced cancer often suffer from severe malnutrition and gastrointestinal obstruction. This population could benefit from home parenteral nutrition (HPN). The aim of this study was to observe the outcome of patients with advanced cancer patients who were eligible for HPN. METHODS: All patients in the nutrition clinic who received HPN over the past 7 y were included in the present study. We compared patients with advanced cancer with the noncancer population in terms of hospitalization rate and mortality. RESULTS: Of 221 advanced cancer patients, 153 who had no oral/enteral intake and who received HPN survived. Of these, 35% survived for 6 mo, 27% for 1 y, 18.9% survived 2 y, and 3.9% survived for the 7 y of the follow-up. Hospitalization rate was not significantly different from the noncancer population. CONCLUSION: These results show that HPN is a relevant palliative therapy for patients with advanced cancer patients without oral or enteral feeding access.

RESUMO

The distribution of HLA class II alleles and genotypes in Israelis of different ethnic origin with adult-onset type 1 diabetes (T1D) was examined. The results were compared with published findings in healthy Israelis and childhood-onset T1D Israelis. An additional comparison was made between subgroups of patients with rapidly and slowly progressive adult-onset T1D (LADA). A DNA-based low-resolution analysis was performed for DRB1* and DQB1* alleles and a high-resolution analysis for DRB1*04 and DQB1*1 alleles. In all, 87% of the study group was positive for DRB1*03 or DRB1*04 compared with 36% of the healthy controls. The main alleles accounting for susceptibility to T1D were DRB1*0402, found in 77.9% of carriers of DRB1*04 and DQB1*0302, found in 74.6% of carriers of DQB1*03. The DQB1*0602 was not detected in any patient. The distribution was similar to that reported in Israeli children with T1D and significantly different from healthy Israelis. There was no significant difference in the distribution of HLA class II alleles between patients with rapidly progressive T1D or LADA. It may be concluded that the different ages of onset of T1D and its different forms of development in Israeli patients are apparently not caused by a different prevalence of HLA class II alleles.

RESUMO

Telomeres serve as a mitotic clock and biological marker of senescence. Diabetes mellitus (DM) is associated with damage to target organs and premature aging. We assessed the effect of glycemic control on telomere dynamics in arterial cells of 58 patients undergoing coronary artery bypass and in mononuclear blood cells of other diabetic (32 type I and 47 type II) patients comparing well controlled to uncontrolled patients. All were compared to age-dependent curve of healthy controls. Telomeres were significantly shorter in the arteries of diabetic versus non-diabetic patients (p=0.049) and in mononuclear cells of both type I and type II diabetes. In all study groups good glycemic control attenuated shortening of the telomeres. In arterial cells good glycemic control attenuated, but not abolished, the telomere shortening. In type II DM the mononuclear telomere attrition was completely prevented by adequate glycemic control. Telomere shortening in mononuclear cells of type I diabetic patients was attenuated but not prevented by good glycemic control. Results of this study suggest that diabetes is associated with premature cellular senescence which can be prevented by good glycemic control in type II DM and reduced in type I DM.

RESUMO

Overnutrition and sedentary lifestyle result in overweight or obesity defined as abnormal or excessive fat accumulation that may impair health. According to the WHO, the worldwide prevalence of obesity nearly doubled between 1980 and 2008. In 2008, over 50% of both men and women in the WHO European Region were overweight, and approximately 23% of women and 20% of men were obese. Comprehensive diagnostic and therapeutic approaches should include nutritional treatment to favor the best metabolic and nutritional outcome, as well as to induce potential disease-specific benefits from selected nutritional regimens. Obesity is usually accompanied by an increased muscle mass. This might explain why obesity, under particular circumstances such as cancer or high age, might have protective effects, a phenomenon named the 'obesity paradox'. However, loss of muscle mass or function can also occur, which is associated with poor prognosis and termed 'sarcopenic obesity'. Therefore, treatment recommendations may need to be individualized and adapted to co-morbidities. Since obesity is a chronic systemic disease it requires a multidisciplinary approach, both at the level of prevention and therapy including weight loss and maintenance. In the present personal review and position paper, authors from different disciplines including endocrinology, gastroenterology, nephrology, pediatrics, surgery, geriatrics, intensive care medicine, psychology and psychiatry, sports medicine and rheumatology, both at the basic science and clinical level, present their view on the topic and underline the necessity to provide a multidisciplinary approach, to address this epidemic.

RESUMO

OBJECTIVE: We compared the Deltatrac II, the M-COVX, and the Evita 4 metabolic monitoring devices under clinical conditions. METHODS: A prospective simultaneous clinical comparison was performed in a general intensive care department of a tertiary university hospital in 43 ventilated, critically ill patients. The monitors were compared simultaneously. After 30 min of steady state, oxygen consumption per unit time, carbon dioxide consumption per unit time, resting energy expenditure, and respiratory quotient were recorded for the Deltatrac II; the same parameters in addition to end-tidal carbon dioxide and fraction of inspired oxygen were recorded for the M-COVX; and carbon dioxide consumption per unit time, end-tidal carbon dioxide, and fraction of inspired oxygen were recorded for the Evita 4. Pulmonary gas-exchange measurements from the Deltatrac II and resting energy expenditure and respiratory quotient from the M-COVX were obtained after 30 min. The other parameters were calculated from the last five measurements obtained at the end of the study period. RESULTS: A good correlation was found between oxygen consumption per unit time and resting energy expenditure as obtained from the Deltatrac II and the M-COVX (r = 0.76 and 0.75, respectively; P < 0.001), but the correlation was lower between carbon dioxide consumption per unit time as obtained from the Deltatrac II and the M-COVX or Evita 4 (r = 0.67 and 0.48, respectively). Agreement between the different methods did not reach clinical acceptability, exceeding a 20% difference using the Bland-Altman statistical methods. CONCLUSION: Poor agreement was found between the Deltatrac II and M-COVX or Evita 4 metabolic monitors, despite a good correlation between measurements, leading to the conclusion that the M-COVX and Evita 4 provide less accurate measurements of metabolic gas exchange in stable ventilated patients. These devices can be used for daily nutritional assessment and continuous monitoring, but the Deltatrac II remains the method of choice for metabolic measurement.

RESUMO

Critically ill patients often require nutrition support, but accurately determining energy needs in these patients is difficult. Energy expenditure is affected by patient characteristics such as weight, height, age, and sex but is also influenced by factors such as body temperature, nutrition support, sepsis, sedation, and therapies. Using predictive equations to estimate energy needs is known to be inaccurate. Therefore, indirect calorimetry measurement is considered the gold standard to evaluate energy needs in clinical practice. This review defines the indications, limitations, and pitfalls of this technique and gives practice suggestions in various clinical situations.

RESUMO

OBJECTIVES: This study assessed the safety and efficacy of a new beverage on suppressing hunger and improving feelings of satiety in healthy volunteers. METHODS: In the safety study, participants (n = 269) received either 1) a control beverage-coffee alone (group C); 2) the study beverage-coffee, whey protein, inulin, and dextrin (group S); or 3) an inulin-enriched beverage (I group). The study was held over a 7-d period during which participants were required to consume 2 cups of coffee a day. RESULTS: There were no significant differences between the groups in any reported adverse effects, apart from more abdominal pain after the first cup in group I versus S (P < 0.05). CONCLUSIONS: This study showed that a coffee beverage enriched with inulin, dextrin, and whey is safe and has possible benefits with regard to feelings of hunger and satiety 2 h after ingestion.

RESUMO

OBJECTIVE: The aim of this study was to assess the validity and reliability of the Fitmate metabolic system in measuring the oxygen consumption and resting metabolic rate (RMR) in ambulatory and hospitalized patients. METHODS: We conducted a prospective simultaneous clinical comparison. We enrolled 37 patients (19 women and 18 men) for the four groups of the study. Group 1 (n = 12) included patients receiving home parenteral nutrition. Group 2 (n = 5) included diabetic overweight outpatients with body mass index >30 kg/m(2) and hemoglobin A1c > 8 g/dL. Group 3 (n = 10) included hospitalized patients receiving artificial nutrition. Group 4 (n = 10) included patients with congenital heart disease, pulmonary hypertension of any etiology, and other heart disease who have had hemodynamic evaluation during catheterization by the adult congenital team. The patients were tested successively during the same session using the Fitmate metabolic system for 15 min and the Deltatrac II metabolic monitor for 20 min, measuring resting energy expenditure and oxygen consumption. The test was conducted in random order. RESULTS: No significant differences were found between Fit Mate and Deltatrac II for oxygen consumption (238 ± 18 and 240 ± 18 mL/min, respectively, P = 0.72, r = 0.86, mean ± SD absolute difference 22.32 ± 16.99 mL/min) or RMR (1659 ± 122.34 and 1625 ± 118.4 kcal/d, P = 0.28, r = 0.87, mean ± SD absolute difference 152.9 ± 111.95 kcal/d). A degree of limit of agreement (403 kcal) was observed using the Bland-Altman test. When compared with Harris-Benedict predictive equations, Fitmate was found to be superior in accuracy. CONCLUSIONS: These data indicate that the Fitmate using a mask provided a fair evaluation of REE despite a large limit of agreement. It remains a reliable and valid system for measuring oxygen consumption and RMR in nonventilated patients.

RESUMO

BACKGROUND & AIMS: Nutrition can interfere with organ function during the different stages of transplantation. Oral fish oil supplementation to kidney transplant recipients has been found to improve renal function. The aim of the present study was to determine the safety and tolerance of intravenous administration of fish-oil emulsion to heart-beating brain-dead donors and, subsequently, to the kidney recipients, and to assess its effects on renal function. METHODS: A lipid emulsion enriched with omega-3 fatty acids (MLF 541) was given intravenously to 8 heart-beating, brain-dead organ donors for up to 4 h before organ harvesting and to the kidney recipients for 5 days postoperatively. Hemodynamic, biochemistry and hematological parameters were measured before and at the end of lipid administration in the donors and on posttransplantation days 1, 5, 30 and 180 in the recipients. Findings in the recipients were compared with a concurrent control group. RESULTS: There were no significant changes in hemodynamic or laboratory parameters during the MLF infusion in the donors or the 5 days of MLF administration in the recipients. Blood urea nitrogen and serum creatinine levels decreased over time in both the study and control recipients (P < 0.05 for both), with no significant between-group difference at any of the time points studied. CONCLUSIONS: Administration of MLF 541 is safe in organ donors and in kidney recipients. Further studies involving nutrients as pharmacological agents in organ transplantation are warranted.

RESUMO

OBJECTIVES: To understand the impact of nocturnal and daytime non-severe hypoglycemic events on healthcare systems, work productivity and quality of life in people with type 1 or type 2 diabetes. METHODS: People with diabetes who experienced a non-severe hypoglycemic event in the 4 weeks prior to the survey were eligible to participate in a nocturnal and/or daytime hypoglycemia survey. Surveys were conducted in Argentina, Australia, Brazil, Israel, Mexico and South Africa. RESULTS: In total, 300 respondents were included in nocturnal/daytime hypoglycemia surveys (50/participating country/survey). All respondents with type 1 diabetes and 68%/62% (nocturnal/daytime) with type 2 diabetes were on insulin treatment. After an event, 25%/30% (nocturnal/daytime) of respondents decreased their insulin dose and 39%/36% (nocturnal/daytime) contacted a healthcare professional. In the week after an event, respondents performed an average of 5.6/6.4 (nocturnal/daytime) additional blood glucose tests. Almost half of the respondents (44%) reported that the event had a high impact on the quality of their sleep. Among nocturnal survey respondents working for pay, 29% went to work late, 16% left work early and 12% reported missing one or more full work days due to the surveyed event. In addition, 50%/39% (nocturnal/daytime) indicated that the event had a high impact on their fear of future hypoglycemia. CONCLUSIONS: The findings suggest that nocturnal and daytime non-severe hypoglycemic events have a large financial and psychosocial impact. Diabetes management that minimizes hypoglycemia while maintaining good glycemic control may positively impact upon the psychological wellbeing of people with diabetes, as well as reducing healthcare costs and increasing work productivity.

RESUMO

BACKGROUND: It has been previously shown that platelets of patients with diabetes are more reactive and less responsive to anti-platelet drugs compared with platelets from subjects without diabetes. Studies examining the effect of glycemic control on platelet reactivity have yielded conflicting data. Thus, in this study, we sought to explore the effect of tight glycemic control on platelet reactivity in patients with long standing uncontrolled diabetes. METHODS: The study included 30 patients with long-standing treated diabetes and a baseline HbA1c level of ≥ 8.5%. All patients were treated with aspirin and statins. Patients were tested at baseline and after 3 months of intensive glycemic and metabolic control. The treatment goal was to achieve a HbA1c level of ≤ 7%. Platelet reactivity was assessed by light transmission aggregation in response to 5 and 10 µM ADP and to 0.5mg/ml arachidonic acid (AA). Additonally, platelet activation was assessed by plasma levels of soluble P-selectin using an enzyme-linked immunosorbent assay. RESULTS: The mean duration of diabetes from the time of diagnosis was 20.46 ± 9.31 years. Baseline HbA1c was 9.4 ± 0.8%. Following the intensive glycemic control period, the HbA1C level decreased to 8.1 ± 0.8% (P < 0.0001). Other laboratory parameters did not change significantly except for triglyceride levels, which decreased. None of the platelet aggregation studies nor P-selectin levels differed between baseline and after 3 months of intensive glycemic control. CONCLUSIONS: Intensive glycemic control in patients with longstanding uncontrolled diabetes does not seem to result in a reduction in platelet reactivity.

RESUMO

OBJECTIVES: The aim of this preliminary study was to compare the effectiveness of domperidone and acupuncture for the management of diabetic gastroparesis. METHODS: This was a preliminary, prospective non-randomised, unblinded case-crossover study conducted in patients with longstanding, uncontrolled diabetes mellitus and gastroparesis. All patients received domperidone (20 mg four times a day) for 12 weeks, followed by a 2-3 week washout period, and then biweekly acupuncture treatments for 8 weeks. Gastric emptying rate, glucose and glycated haemoglobin (HbA1C) levels were measured at start and end of each treatment period. At each of these timepoints patients completed the Gastroparesis Cardinal Symptom Index (GCSI), the Satisfaction with Life Scale (SWLS), and the Short-Form 36 Health Survey Update (SF-36). RESULTS: The trial was curtailed after only eight participants could be recruited in 3 years. The mean age of patients was 57.1±9.9 years, the male:female ratio was 1:7 and mean body mass index (kg/m(2)) was 25.2±1.2. There was no change in any of the outcome parameters after treatment with domperidone. Acupuncture was associated with a decrease in scores for almost all cardinal symptoms of the GCSI, as well as in increased total score on the SWLS (p=0.002) and the social functioning domain of the SF-36 (p=0.054). Acupuncture did not lead to an improvement in gastric emptying, or glucose control from baseline. CONCLUSIONS: Acupuncture treatment may lead to symptomatic improvement in patients with diabetic gastroparesis. Within the limitations of this preliminary, non-randomised and unblinded study, it appears that this effect may be due to non-specific mechanisms.

RESUMO

OBJECTIVE: To test the effects of implementing computer-assisted Monitoring of Individual Needs in Diabetes (MIND) in routine diabetes care on psychological status and glycemic control, identify predictors of poor psychological outcomes, and evaluate care providers' experiences. RESEARCH DESIGN AND METHODS: The MIND procedure was implemented as part of the annual review in diabetes clinics across eight countries in a prospective observational study with a 1-year follow-up. MIND encompasses well-being (World Health Organization Five Well-Being Index [WHO-5]), diabetes-related distress (Problem Areas in Diabetes [PAID]), a Life Event Inventory, and the patient's agenda for their consultation. Medical data and agreed case-management actions were retrieved from the charts. RESULTS: Of the total 1,567 patients, 891 patients (57%) were monitored at a 1-year follow-up. Twenty-eight percent of the patients screened positive for depression and/or diabetes distress at baseline and considered cases, 17% of whom were receiving psychological care. Cases were significantly more often female and had type 2 diabetes and worse glycemic control compared with noncases. Clinically relevant improvements in WHO-5 and PAID were observed over time in cases, irrespective of referral (effects sizes 0.59 and 0.48, respectively; P < 0.0001). Glycemic control did not change. Female sex, life events, and concomitant chronic diseases were predictors of poor psychological outcomes. MIND was well received by patients and staff. CONCLUSIONS: MIND appears suitable for screening and discussion of emotional distress as part of the annual review. Broader dissemination in diabetes care is recommendable, but sustainability will depend on reimbursement and availability of support services.
