First record of a spawning aggregation for the tropical eastern Pacific endemic grouper Mycteroperca olfax in the Galapagos Marine Reserve.

This study provides direct and indirect evidence of temporally and spatially consistent spawning aggregations for the grouper Mycteroperca olfax. Recently reported declines in population numbers, probably related to the direct targeting of aggregations by artisanal fishermen, highlight the urgent need for species-specific management actions in the Galapagos Marine Reserve, such as minimum and maximum landing sizes, and the importance of protecting key aggregation sites with the declaration of no-take areas and the establishment of total fishing bans during the reproductive season.

Impact of diagnosis of diabetes on health-related quality of life among high risk individuals: the Diabetes Prevention Program outcomes study.

PURPOSE: The purpose of this study is to assess if diagnosis of type 2 diabetes affected health-related quality of life (HRQoL) among participants in the Diabetes Prevention Program/Diabetes Prevention Program Outcome Study and changes with treatment or diabetes duration. METHODS: 3,210 participants with pre-diabetes were randomized to metformin (MET), intensive lifestyle intervention (ILS), or placebo (PLB). HRQoL was assessed using the SF-36 including: (1) 8 SF-36 subscales; (2) the physical component (PCS) and mental component summary (MCS) scores; and (3) the SF-6D. The sample was categorized by diabetes free versus diagnosed. For diagnosed subgroup, mean scores in the diabetes-free period, at 6 months, 2, 4 and 6 years post-diagnosis, were compared. RESULTS: PCS and SF-6D scores declined in all participants in all treatment arms (P < .001). MCS scores did not change significantly in any treatment arm regardless of diagnosis. ILS participants reported a greater decrease in PCS scores at 6 months post-diagnosis (P < .001) and a more rapid decline immediately post-diagnosis in SF-6D scores (P = .003) than the MET or PLB arms. ILS participants reported a significant decrease in the social functioning subscale at 6 months (P < .001) and two years (P < .001) post-diagnosis. CONCLUSIONS: Participants reported a decline in measures of overall health state (SF-6D) and overall physical HRQoL, whether or not they were diagnosed with diabetes during the study. There was no change in overall mental HRQoL. Participants in the ILS arm with diabetes reported a more significant decline in some HRQoL measures than those in the MET and PLB arms that developed diabetes.

Insulin resistance explains the relationship between novel cardiovascular risk factors and hypertension. The Telde Study.

BACKGROUND: Most studies describing an association between hypertension and an inflammatory/pro-thrombotic state do not assess insulin resistance. AIM: To examine the association between hypertension and new cardiovascular risk factors when considering both classical risk factors and insulin resistance. METHODS: In a population-based sample of 1030 subjects, clinical information and blood samples were obtained. Subjects were classified according to the presence or absence of hypertension, and insulin resistance was estimated using the homeostasis model of assessment (HOMA). To identify variables independently associated with hypertension, a four-model multiple logistic regression was performed: model 1 included novel risk factors (Plasminogen Activator Inhibitor- 1 [PAI-1], fibrinogen, von Willebrand Factor [vWF], lipoprotein(a), homocysteine and C-reactive Protein [CRP]); model 2, novel risk factors plus HOMA; model 3 included both classical (smoking, triglycerides, HDL cholesterol, total cholesterol, waist circumference and diabetes) and novel risk factors and model 4, model 3 plus HOMA. All were adjusted for age, BMI and gender and compared using Akaike's Information Criterion (AIC). RESULTS: In model 1, only PAI-1, age and BMI showed association with hypertension.When HOMA and classical risk factors were also included, PAI-1 was replaced by triglyceride, smoking and diabetes. The lowest AIC value (best adjustment) was displayed by model 4, comprising all of the variables. Only age, BMI, HOMA and smoking remained significantly associated with hypertension. CONCLUSIONS: The novel cardiovascular risk factors assessed do not add information as markers of hypertension when classical risk factors or insulin resistance are included in the evaluation.

Protocol for a feasibility and early efficacy study of the Comprehensive Lifestyle Improvement Program for Prostate Cancer-2 (CLIPP2).

BACKGROUND: Although androgen deprivation therapy (ADT) for prostate cancer demonstrates improved overall and disease-free survival, it is associated with adverse effects such as obesity and metabolic syndrome that increase risk of cardiometabolic disease and diabetes type 2. ADT also leads to fatigue, depression and erectile dysfunction, which reduce quality of life (QoL). Lifestyle modification has shown promise in reducing obesity, metabolic syndrome and diabetes type 2 in other disease types. However, there is a paucity of data regarding the utility of lifestyle modification in men receiving ADT for prostate cancer. METHODS: The primary aim of the Comprehensive Lifestyle Improvement Program for Prostate Cancer-2 (CLIPP2) is to test the feasibility of conducting a 24-week lifestyle modification intervention in men on ADT for prostate cancer. Additionally, it will also determine the effect of this intervention on weight loss, cardiometabolic markers (secondary aim and markers of interest: serum glucose, insulin resistance, hemoglobin A1C and lipid panel), and QoL (tertiary aim). The intervention will be delivered weekly via telephone for the first 10 weeks and bi-weekly for the remaining 14 weeks. Questionnaires and serum samples will be collected at baseline, week 12, and week 24. Anthropometric measurements will be collected at baseline, week 6, week 12, week 18 and week 24. RESULTS: We hypothesize that the CLIPP2 intervention will produce a 7% weight loss that will result in improved markers associated with cardiometabolic disease and type 2 diabetes in the study population. CONCLUSION: Results will provide insight into the role of lifestyle modification in addressing ADT adverse effects as well as provide preliminary data to inform the development of future lifestyle interventions in this area.

Comprehensive Lifestyle Improvement Program for Prostate Cancer (CLIPP) is associated with improvement in weight and components of metabolic syndrome in men exposed to androgen deprivation therapy for prostate cancer.

BACKGROUND: Androgen deprivation therapy (ADT) for prostate cancer is associated with adverse effects, such as obesity and metabolic syndrome, which increase cardiovascular risk, the most common cause of non-cancer mortality in men diagnosed with prostate cancer. The Comprehensive Lifestyle Improvement Program for Prostate Cancer (CLIPP) was created to determine the feasibility of conducing a comprehensive lifestyle modification intervention in men on ADT for prostate cancer and determine its early efficacy in reducing obesity and metabolic syndrome. METHODS: A single-arm, open-label clinical trial was conducted by recruiting 31 men diagnosed with prostate cancer and exposed to ADT within the last 5 years. A multicomponent lifestyle modification program was delivered weekly for 16 weeks by a trained health coach. This was followed by 8 weeks of passive follow-up resulting in a total trial duration of 24 weeks. Feasibility was determined by calculating study recruitment, retention, and adherence rates. Weight and components of metabolic syndrome (waist circumference, triglycerides (TG), high-density lipoprotein (HDL), serum glucose, and blood pressure (BP)) were measured at baseline, 12, and 24 weeks. RESULTS: Recruitment, retention, and adherence rates were 47.1%, 90.3%, and 100%, respectively. Statistically significant improvements were noted between baseline and end of study measurements for weight (206.3 vs. 191.3 lbs, p < 0.001), waist (41.3 vs. 38.8 inches, p < 0.001), systolic BP (144.1 vs. 133.4 mm of Hg, p = 0.014), diastolic BP (83.3 vs. 76.2 mm of Hg, p = 0.0056), TG (146.0 vs. 113.8 mg/dl, p = 0.022), HDL (51.1 vs. 55.0 mg/dl, p = 0.012), and serum glucose (114.0 vs. 103.2 mg/dl, p = 0.013). CONCLUSION: CLIPP demonstrates feasibility and early efficacy of a multicomponent lifestyle modification intervention toward addressing obesity as well as components of metabolic syndrome in men on ADT for prostate cancer. This study provides strong preliminary data to develop future clinical trials in this population.

The effect of in vivo growth hormone treatment on blood gene expression in adults with growth hormone deficiency reveals potential biomarkers to monitor growth hormone therapy.

OBJECTIVE: Growth hormone (GH) replacement therapy is presently utilized in the treatment of adult GH deficiency (AGHD). Adult responses to GH treatment are highly variable and, apart from measurement of IGF-I, few tools are currently available for monitoring GH treatment progress. As GH receptors are expressed in certain blood cell types, changes in gene expression in peripheral blood can reflect perturbations induced as a result of GH therapy. DESIGN/PATIENTS: We have carried out a pilot study to identify GH-responsive genes in blood, and have assessed the utility of GH-responsive genes in monitoring GH therapy in AGHD. Blood was collected from ten women diagnosed with AGHD syndrome both before and 4 weeks after initiation of GH substitutive therapy. RNA was extracted from peripheral blood mononuclear cells (PBMCs) and changes in response to GH were detected using microarray-based gene analysis. RESULTS: All patients responded to GH replacement therapy, with serum levels of IGF-I increasing by an average of 307% (P = 0.0003) while IGFBP-3 increased by an average of 182% (P = 0.0002). Serum levels of triglycerides, LDL-C, HDL-C, APOA1 or APOB did not change after 1 month of GH treatment. By contrast, we detected an increase in Lp(a) serum levels (P = 0.0149). Using a stringent selection cutoff of P

Prevalence of pain and association with quality of life, depression and glycaemic control in patients with diabetes.

AIMS: To determine the prevalence of pain and its association with glycaemic control, mental health and physical functioning in patients with diabetes. METHODS: Cross-sectional data from a multi-site, prospective cohort study of 11 689 participants with diabetes. We analysed the associations of pain severity and interference with glycated haemoglobin (HbA(1c)) measurements and Medical Outcomes Study SF-Mental and Physical Component Summary-12 (MCS-12 and PCS-12) scores. RESULTS: Of participants, 57.8% reported moderate to extreme pain and, compared with those without pain, were somewhat older (60.8 vs. 59.9 years, P < 0.001), more obese (body mass index of 32.1 vs. 29.8 kg/m(2), P < 0.001), more likely to report being depressed or anxious (41.3 vs. 16.2%, P < 0.001) and more likely to report fair or poor health (48.5 vs. 23.1%, P < 0.001). Bivariate comparisons demonstrated that patients with extreme pain had higher HbA(1c) than those without pain (8.3 vs. 8.0%, P = 0.001). In multivariable analyses, pain was not associated with HbA(1c) (P = 0.304) but was strongly associated with worse MCS-12 (P < 0.001), PCS-12 (P < 0.001) and depression (P < 0.001). Depression was 1.3 (95% CI: 1.12, 1.96) times more likely in patients with moderate pain and 2.0 (95% CI: 1.56, 2.46) times more likely in patients with extreme pain. CONCLUSIONS: Moderate to extreme pain was present in 57.8% of diabetic patients. Pain was strongly associated with poorer mental health and physical functioning, but not worse glycaemic control. Recognizing the high prevalence of pain and its strong association with poorer health-related quality of life may be important to improve the comprehensive management of diabetes.

[Goodpasture's syndrome with neurologic involvement and negative ANCA]. / Síndrome de Goodpasture asociado con vasculitiscerebral ANCA negativa.

Goodpasture's syndrome is a rare autoimmune disorder characterized by rapidly progressive glomerulonephritis (RPGN) and alveolar hemorrhage in the presence of antiglomerular basement membrane (anti-GBM) antibodies. Central nervous system involvement is highly unusual in the absence of anti-neutrophil cytoplasmic antibodies. We report the case of a 20-year-old man with RPGN accompanied by bloody sputum, tonic-clonic seizure and high titers of anti-GBM antibody. After treatment with immunosuppressants and plasmapheresis, the patient showed reduced anti-GBM antibody titers and improved neurologic and respiratory symptoms, but renal failure persisted, requiring hemodialysis. Twenty months later, with the disease in remission, he underwent deceased-donor renal transplantation.

[Carotid ultrasound: prevention of heart disease and mortality on haemodialysis]. / La ecografía carotídea es útil para predecir enfermedad coronaria y mortalidad en pacientes en hemodiálisis.

INTRODUCTION: Cardiovascular disease and other complications of atherosclerosis are the most common cause of death in patients with chronic renal failure in maintenance hemodialysis (MHD). Carotid ultrasonography is a simple non-invasive tool to investigate the vascular system, by means of intima media thickness (IMT) measurement and carotid wall calcifications. OBJECTIVE: To determine IMT and the presence of plaques, and their possible clinical relationships; finally we tried to investigate whether they would predict cardiovascular morbidity and mortality in patients in MHD. METHODS: We studied 60 MHD patients (age 68 +/- 13 years, 48% male, 50% diabetics, time on MHD 32 +/- 11 months) and a control group of 274 people matched for age and sex. Follow-up period was 66 +/- 13 months. MEASUREMENTS: Demographic and clinical data, serum levels of homocysteine (tHcy), folic acid (FA) and B6 and B12 vitamins. IMT was measured by high-resolution B-mode ultrasonography. RESULTS: IMT was higher in MHD patients than in those in the control group (0.947 +/- 0.308 vs 0.619 +/- 0.176 mm; P < 0.001). IMT was related with age (r = 0.268; P = 0.038), diabetic (r = 0.650; P < 0.001) and hypertensive condition (r = 0.333; P = 0.012), but not wih lipids, tHcy or FA. Patients who suffered from coronary artery disease, peripheral artery disease or stroke had higher IMT than those without those events (1.156 +/- 0.371 vs 0.875 +/- 0.285 mm; P < 0.001; 1.205 +/- 0.374 vs 0.911 +/- 0.231 mm; P = 0.007; 1.195 +/- 0.264 vs 0.844 +/- 0.251; P < 0.001 respectively). Something similar occurred with the presence of plaques. During the follow-up period 36 patients died (60%), 67% of them due to cardiovascular causes. IMT was higher in patients who died than those who survived (1.020 +/- 0.264 vs 0.858 +/- 0.334 mm; P = 0.044). The survival rate during the observation period was significantly lower in the final IMT fourth (20%) than in the first (72%) (P = 0.014). The presence of carotid plaques was an independent predictor of cardiovascular mortality. CONCLUSIONS: These findings suggests that measurement of carotid IMT and the presence of wall plaques are useful tools to predict cardiovascular events and mortality in patients in MHD.

[Induction treatment by combining immunoglobulins, plasmapheresis and rituximab in hypersensitive patients receiving cadaveric renal allograft]. / Tratamiento de inducción combinando inmunoglobulinas, plasmaféresis y rituximab en pacientes hipersensibilizados que reciben trasplante renal de cadáver.

In our Universitary Hospital of Canarias we iniciated in May 2008 a induction therapy protocol for sensitized patients receiving cadaveric renal graft using intravenous immunoglobulins, plasmapheresis and rituximab plus immunosuppression with prednisone, tacrolimus and mycophenolate mofetil. We present the results of four patients. Everyone had anti-HLA antibodies rate (PRA by CDC) more than 75%, were on a waiting list during 4 to 17 years and follow-up time was 10-14 months after transplantation. Patient and graft survival in this period was 100%. Only one patient suffered a humoral acute rejection and another one cellular rejection, in both cases reversible with treatment. During the first year, no evidence of de novo donor-specific antibodies was detected. All patients had significantly reduced the CD19+ cells percentage after infusion of rituximab. Neurological symptoms suggestive of progressive multifocal leukoencephalopathy or serious viral infections after transplantation have not been observed. Additionally, no immediate side effects were observed after administration of medication. In summary, induction therapy by combining immunoglobulin, plasmapheresis and rituximab in hypersensitive patients allows the realization of deceased kidney transplantation with good results in the short and medium-term without serious side effects. It remains to know whether this success will continue in the long term.

Thyrotropin levels and their relationship with cardiovascular risk factors in the island of Gran Canaria, Spain. Implications of lowering the upper reference limit of thyrotropin stimulating hormone.

OBJECTIVE: To characterize the cardiovascular risk profile of subjects with high and normal-high concentrations of serum TSH in a sample of adult Spanish subjects from the island of Gran Canaria. DESIGN: Cross-sectional population-based study. SUBJECTS: After excluding 28 individuals on current treatment with levothyroxine and 9 others with TSH levels below the range of normality (0.3-4.9 mU/l), 704 randomly selected subjects (412 women; age range: 30-82 yr) belonging to the Telde Study were assessed. MEASUREMENTS: Participants underwent physical examination and fasting blood analyses to determinate TSH, serum lipids, homocysteine, fibrinogen, von Willebrand factor, plasminogen activator inhibitor- 1, C-reactive protein, and insulin. RESULTS: Twenty-nine participants had serum TSH concentrations above the normal range of normality. Among all the studied variables, only female sex and diastolic blood pressure were significantly associated with TSH levels > or =5 mU/l in a multivariate logistic regression analysis. If the upper normal limit of TSH was reduced up to 2.4 mU/l, an additional group of 106 subjects would be considered to have elevated TSH levels. A serum TSH > or =2.5 mU/l was positive and independently associated with female sex, body mass index, total cholesterol, and homocysteine, and negatively associated with smoking. CONCLUSIONS: Although the impact of serum TSH levels on cardiovascular risk cannot be established from these findings, TSH values within the upper part of the usually accepted normal range were demonstrated to be associated with well-recognized risk factors for cardiovascular disease.

Visceral Leishmaniasis in Renal Transplant Recipients: Report of 2 Cases.

Visceral leishmaniasis is a disease caused by the protozoan Leishmania and is transmitted by Lutzomyia longipalpis (sand fly). It is an endemic parasitic infection in numerous areas around the Mediterranean basin. Though immunocompetent patients may not develop the disease, in transplant recipients the use of corticoids and intensified immunosuppressants to prevent graft rejection may accelerate the disease, causing severe damage to the liver, spleen, and hematopoietic system. We report 2 cases of visceral leishmaniasis with an atypical presentation in transplant recipients. The first patient, who had a kidney transplant, was treated successfully with liposomal amphotericin B, and the second patient, a combined kidney-pancreas transplant recipient, suffered a relapse 3 years after treatment. Visceral leishmaniasis should be considered in the differential diagnosis of pancytopenia or unexplained fever occurring after organ transplantation in patients living in endemic areas or returning from endemic countries.

Efficacy of a mobile hypertension prevention delivery platform with human coaching.

This pilot study evaluated the efficacy of a Hypertension Prevention Program (HPP) administered through a mobile application platform with human coaching (app) on reduction in blood pressure and weight in 50 adults with prehypertension or hypertension. Participants were recruited into a 24-week mobile application intervention to administer the HPP between January 2016 and July 2016. Dietary elements of the programme were based on the Dietary Approaches to Stop Hypertension. The programme included in-app human coaching with bi-weekly phone calls, meal logging, blood pressure tracking and educational material. Main outcome variables included change in systolic and diastolic blood pressure, hypertension category, and weight loss. Data were analysed between October 2016 and December 2016. The HPP yielded overall improvements in weight (-3.04±4.04 kg, P=<0.001), diastolic blood pressure (-5.06±11.89 mm Hg, P=0.004), and hypertension category (-0.48±0.74 mm Hg, P=<0.001). Sustained engagement of 80% resulted in significant reductions in systolic blood pressure (-7.75±12.56, P=<0.001) and weight (-3.73±4.01 kg, P<0.001) for programme completers, contributing to hypertension category change (-0.58±0.64 mm Hg, P<0.001). Mobile delivery of a lifestyle intervention for hypertension prevention showed short-term potential to reduce risk of hypertension, supporting the need for longer studies to investigate the use of mHealth lifestyle modification to reduce the risk of hypertension, a public health priority.

Hepatitis C Treatment With Direct-Acting Antivirals in Kidney Transplant: Preliminary Results From a Multicenter Study.

Hepatitis C (HC) is a very relevant negative prognosis factor for graft and transplant recipient survival. New direct-acting antivirals (DAAs) allow us to solve this problem in an effective way. It is crucial to understand their real impact in our daily practice. We analyzed treatment results with DAA, free of interferon, in kidney transplant recipients (KTRs) from 15 Spanish hospitals (Grupo Español de Actualización en Trasplante), regarding effectiveness, tolerance, and impact on immunosuppression, renal function-proteinuria, and diabetes. One hundred nineteen KTRs were included (9 combined liver-kidney transplants). The main DAA used was sofobusvir (91%) combined with ledipasvir (55%), simeprevir (14%), or daclatasvir (13%); in 9 cases (7%), a paritaprevir-ritonavir-ombitasvir-dasabuvir combination (3D) was used; Ribavirin was used as a coadjuvant in 18%. Side effects were limited (23.5%) and without relevance in general, except in 7 patients for whom we needed to interrupt the treatment due to neurotoxicity (1) caused by drug interaction (3D and tacrolimus) or anemia (3) by Ribavirin or others. Ninety-four patients had completed the treatment when data were analyzed: virological response was seen in 97.8% % of cases. Liver function analysis improved: 84% normal versus 21% before starting the treatment (P < .001). Renal function and proteinuria did not change. Tacrolimus level at the end of DAA-treatment was significantly lower with respect to the beginning (5.8 ± 2.1 ng/mL vs. 7.4 ± 1.8 ng/mL, P = .03), despite a slight increase in the dose (2.6 mg/d vs. 2.3 mg/d, P = .17). DAA are highly effective in the treatment of hepatitis C in KTRs with good tolerance in general, making it possible to solve the problem and have a good chance to improve the prognosis in our transplantation patients. The use of these therapies in KTRs requires special control and coordination with digestive professionals, especially if 3D or Ribavirin is used.

Improved cardiovascular risk profile of patients with type 1 diabetes mellitus and renal failure after simultaneous pancreas-kidney transplantation.

INTRODUCTION: The prognosis of patients with type 1 diabetes mellitus and chronic renal failure improves after simultaneous pancreas-kidney (SPK) transplantation. Good control of glycemia and other cardiovascular risk factors may positively influence prognosis. The objective of this study was to evaluate changes in cardiovascular risk factors after SKP. PATIENTS AND METHODS: We studied 13 patients (aged 36 +/- 8 years, 7 women) before and 12 months after SPK transplantation. All were treated with thymoglobulin, prednisone, tacrolimus, and mycophenolate mofetil. We compared the following pre- and post-SPK parameters: glycemia, HbA(1)c, total cholesterol, HDL, LDL, triglycerides, systolic (sBP), diastolic blood pressure (dBP), and body mass index (BMI). RESULTS: Twelve months after SPK transplantation, glycemia, HbA(1)c and triglycerides significantly decreased (P < .001; P < .001, and P < .002, respectively), as did sBP (P < .002) and dBP (P < .001). No changes were found for BMI or total, HDL and LDL cholesterol values. The number of patients requiring antihypertensive therapy fell (13 versus 3; P < .002), as did the number of drugs (2.3 +/- 0.8 versus 0.4 +/- 0.7; P < .001). The number of patients requiring statins also fell (11 versus 3; P < .002). At 12 months, all patients had normal renal function (creatinine clearance 85 +/- 10 mL/min) and required no insulin; four had microalbuminuria. CONCLUSION: These interim results show an improved cardiovascular risk profile 12 months after SPK transplantation, which lays the basis for a more favorable long-term prognosis.

Detection and treatment of post kidney transplant hyperglycemia: a Spanish multicenter cross-sectional study.

INTRODUCTION: The prevalence of diabetes mellitus (DM) is greater among patients with solid organ transplants than in the general population, although the factors associated with posttransplant DM (PTDM) are unknown. OBJECTIVES: The objective of this study was to estimate the prevalence of and assess the risk factors for PTDM. PATIENTS AND METHODS: We included outpatients with functioning isolated solid organ allografts (kidney, liver, heart, and lung). We collected demographic and posttransplant clinical data that included DM diagnostic ADA criteria, DM treatment, DM family history, presence of hepatitis C virus (HCV), immunosuppression treatment, hypertension, and dyslipidemia. RESULTS: A total of 2178 patients included, 1410 kidney recipients, 489 liver transplants, 207 heart transplants, and 72 lung recipients. Seventeen and four-tenths percent of the patients who did not have DM prior to transplantation, developed PTDM (median time: 79 days). A greater prevalence was observed among patients with a family history, HCV, and tacrolimus treatment (with or without steroids P < .05). By logistic regression analyses, OR for these factors were 1.51, 1.65, and 1.38, respectively. Of those patients who did not suffer PTDM, 55.2% showed basal blood glucose values under 100 mg/dL; only 68% presented with a hemoglobin Alc under 6. CONCLUSIONS: The prevalence of PTDM among kidney recipients was higher than that in the general population. DM family history, HCV positive, and tacrolimus were risk factors associated with this entity.

[Improved short-term cardiovascular profile after simultaneous pancreas-kidney transplantation]. / Evolución a corto plazo de los factores de riesgo cardiovascular tras el trasplante reno-pancreático.

The prognosis of type 1 diabetes mellitus (T1DM) patients with chronic renal failure (CRF) improves after simultaneous pancreas-kidney (SPK) transplantation. In order to evaluate the changes in cardio-vascular risk (CVR) factors after SKP, we studied nine recipients before and 6 months after SPK. There were five females and four males, with a mean age of 37 +/- 8 years, duration of diabetes of 24 +/- 5 years, three of them before starting dialysis, and six on dialysis (hemodialysis = 5; peritoneal dialysis = 1). Before SPK, all patients received anti-hypertensive therapy (1-4 drugs; mean 2.2 +/- 0.9) and eight received statins. At 6 months after SPK, all patients were under triple immunosuppressive therapy (steroids + tacrolimus + MMF) without statins. They had normal renal function (Plasma Creatinine = 1.2 +/- 0.3 mg/dl) and pancreatic endocrine function (glycemia = 80 +/- 8 mg/dl). HbA1c decreased significantly (8.4 +/- 1.2 vs 4.7 +/- 0.6%; p < 0.007) with a value > 7% in seven patients before SPK and in none 6 months after SKP transplantation (p < 0.001). Although Body Mass Index increased (23 +/- 2 vs 25 +/- 3 kg/m2; p < 0.05), plasma triglycerides decreased (130 +/- 51 vs 88 +/- 33 mg/dl; p < 0.05), and total cholesterol, LDL-cholesterol and HDL-cholesterol were similar. Systolic and diastolic blood pressure (BP) decreased (156 +/- 7 vs 133 +/- 15; p < 0.01 and 96 +/- 7 vs 79 +/- 9; p < 0.007) with only two patients on anti-hypertensive therapy (1 drug). Likewise, before transplantation all patients were hypertensive (six grade 1 and three grade 2) while this was observed in only two at the end of follow-up (both grade 1) (p < 0.001). In conclusion, SPK transplantation with good renal and pancreatic function is associated with a short-term improvement in CVR profile.

Same eyes, different doctors: differences in primary care physician referrals for diabetic retinopathy screening.

OBJECTIVE: To analyze eye care specialist referral patterns for the diabetic patients of primary care physicians. RESEARCH DESIGN AND METHODS: In 1993, we conducted a census of primary care physicians to evaluate practice patterns relating to diabetes care in the state of Indiana. Using a logistic regression model and data from this census, we compared 1) physicians' odds of referring type II diabetic patients to an optometrist, as opposed to an ophthalmologist, with those of type I diabetic patients and 2) the referral odds ratios of type II to type I diabetic patients between metropolitan and nonmetropolitan counties. RESULTS: Overall, 10% of the physicians in our study most often refer some patients to an optometrist. Physicians are more likely to refer their type II diabetic patients to an optometrist, as opposed to an ophthalmologist, than they are to refer type I diabetic patients, both before and after adjustment for covariates. Physicians who practice in metropolitan counties are 1.55 times more likely to refer their type II diabetic patients than their type I diabetic patients to an optometrist. In nonmetropolitan counties, physicians are 2.5 times more likely to refer their type II diabetic patients to an optometrist. The difference between metropolitan and nonmetropolitan physicians is significant (P = 0.027). CONCLUSIONS: Some physicians mostly refer their diabetic patients to optometrists, instead of ophthalmologists, for eye examinations intended to discover early signs of diabetic eye disease. Type II diabetic patients are more likely to be referred to an optometrist, instead of an ophthalmologist, than are type I diabetic patients. In nonmetropolitan areas, the difference in referral patterns becomes even more marked.

Characteristics of adolescents with poorly controlled diabetes referred to a tertiary care center.

The medical and psychosocial findings concerning 15 adolescents with poorly controlled diabetes referred to a tertiary center are reviewed. While referring physicians usually attributed poor metabolic control to an unusual idiosyncratic pathophysiologic aspect of diabetes, all patients were managed by conventional treatment regimens. Psychosocial problems, including excessive school absence, depression, and social isolation were frequent in this population, and in eight families emotional factors appeared to contribute to the development and persistence of poor metabolic control. Eight patients accepted psychosocial intervention consisting of individual, family, and/or group counseling. Not one of the patients has been hospitalized for ketoacidosis in the subsequent 12-18-mo period, and their psychosocial functioning as adolescents is improved. Hemoglobin A1c levels remained elevated. Psychosocial factors in adolescents experiencing poor metabolic control should be addressed.
