RESUMO
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.

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.

RESUMO
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.

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 (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.

BACKGROUND: C3 glomerulonephritis (C3GN) is an unusual entity that is caused by dysregulation and hyperactivity of the alternative complement pathway. Renal biopsy immunofluorescence study shows C3 deposits with absence of immunoglobulins and markers of the classical complement pathway. More than 50% of cases develop end-stage renal disease. Less well-known is the course of C3GN after kidney transplantation. CASE REPORT: We present the case of a 60-year-old woman with chronic kidney disease secondary to chronic glomerulonephritis of unknown origin who received a kidney transplant. Two years later, she presented worsening renal function with non-nephrotic proteinuria and microhematuria. Complement testing revealed low serum levels of C3. Kidney biopsy showed alterations compatible with C3GN that we interpreted as a relapse of the underlying disease.

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.

BACKGROUND: Induction therapy for simultaneous pancreas-kidney (SPK) transplantation. Both thymoglobulin (ATG) and basiliximab are the most-used types of induction antibodies therapies in clinical practice. The aim of our report was to analyze our experience comparing 2 induction therapies, for SPK transplantation in terms of pancreas and patient survival, as well as rejection rate. METHODS: We reviewed retrospectively a total of 97 SPK transplantations in our institution. The cases were divided according to induction therapy in 2 groups, basiliximab (n = 38) and ATG (n = 59). Rejection, patient and graft survival, and postoperative complications were analyzed. RESULTS: Survival in the ATG group was better without statistical difference at 1-, 3-, and 5-year follow-up (97%, 95%, and 95% versus 92%, 90%, and 87%, respectively). No difference was detected in pancreas graft survival after 1-, 3-, and 5-year follow-up (basiliximab 85%, 80%, and 77% versus ATG 84%, 84%, and 81%, respectively; log-rank, 0.847). Overall cellular rejection and early rejection were more common in the basiliximab group (30 versus 14%, and 21% versus 6%). In the multivariate analysis considering human leukocyte antigen (HLA) mismatches, the ATG group was a protective factor for cellular rejection. Major complications (Grade III-IV) and median length of the hospital stay were higher in the basiliximab group (55% versus 34%, P = .057, and 21 versus 16 days, P = .056). CONCLUSIONS: The pancreas graft survival was not affected by induction therapy. ATG induction therapy compared with basiliximab is associated with lower overall and early rejection rate. Over time this difference disappears.

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.

BACKGROUND: Pancreas transplantation offers excellent outcomes today in patients who have type-1 diabetes mellitus (DM) with difficult control in terms of increasing patient and pancreatic graft survival. Different factors in donors, recipients, and the perioperative period have been associated with long-term graft survival. The aim of this study was to compare pancreatic graft survival in simultaneous pancreas-kidney transplantation (SPK) and the other two modalities, pancreas-alone and pancreas-after-kidney transplantation (non-SPK), at our institution. METHODS: This retrospective cohort study included 63 pancreas transplantation patients from January 2007 to May 2012 at our institution. The patients were divided into two groups: SPK and non-SPK transplantations. We excluded those patients who had transplants with vascular graft loss. The primary endpoint was 1-year and overall graft survival with consideration of multiple relevant variables. Non-parametric tests were calculated with the statistical package SPSS 20 (SPSS INC, Chicago, IL). RESULTS: The 1-year and overall graft survival in this period was 87.3% and 82.5%, respectively. The median follow-up was 963 days. The causes of graft loss were vascular (64%) and immunologic (34%). Finally, we included 56 pancreas transplantations, 46 (82%) were SPK and 10 (18%) non-SPK. The donor and recipient characteristics were similar in both groups, except for the duration of DM (SPK 22 years vs. non-SPK 29 years) and recipient body mass index (SPK 23 vs. non-SPK 28); P = .042 and P = .003, respectively. The cold ischemia time was 563 minutes (standard deviation, 145). Bivariate analysis showed that long-term graft loss was only influenced by matching for gender (P = .023). Using the Kaplan-Meier method, the pancreas graft survival was better in SPK than in non-SPK transplants (log rank .038). CONCLUSIONS: Patients who receive pancreas-alone or pancreas-after-kidney grafts have shorter long-term graft survival. Multiple strategies should be applied to improve immunologic surveillance and obtain an early diagnosis of graft rejection.

BACKGROUND: Vascular graft thrombosis (VGT) is still the achuilles heel in pancreas transplantation (PT); it is the main cause of nonimmunologic graft loss. Early diagnosis is essential to avoid transplantectomy. The aim of our study was to analyze the peak amylase during the first 3 days after PT as risk factor for VGT. METHODS: This retrospective study included 58 pancreas transplants in 55 patients from January 2007 to November 2011. They underwent an anticoagulation protocol based on unfractionated heparin and low-molecular-weight heparin. The technique consisted of enteric drainage and systemic venous drainage. The primary endpoint was VGT with consideration of multiple relevant variables. The maximum amylase level was determined during the first 3 days after transplantation. A receiver operating characteristic analysis was performed to establish a cutoff point as (mean plus one standard deviation; 745 mg/dL), calculating the sensitivity, specificity, and predictive values. RESULTS: Recipient characteristics were 71% males with an overall mean age of 39 years (range, 23-55) and body mass index 24 (range, 19-36). The donor sex was similar. Mean donor age was 32 years with occurrences of hypotension in 9%, cerebrovascular brain death in 46%. Mean ischemia time was 10 hours and 45 minutes. Mean blood amylase peak was 395 mg/dL. Seven VGT cases were diagnosed during the postoperative period including six with complete thrombosis requring transplantectomy. Bivariate analysis showed the group of subjects with amylase levels above 745 mg/dL to display on eight-fold greater risk for VGT (odds ratio = 8.6; P = .032). The area under the curve of blood amylase peak during the first 3 days to detect VGT was 0.630 (95% confidence interval 0.41-0.84). CONCLUSIONS: A blood amylase peak above 745 mg/dL in the first 3 days after transplantation was associated with risk for VGT.

Cirrhosis represents a late stage of hepatic fibrosis and leads to high morbidity and mortality, and the most frequent complication is ascites. Only a few patients with advanced cirrhosis have 'refractory ascites' and do not respond to conventional treatment. Repeated paracentesis for evacuation is considered the treatment of choice in these cases. A large proportion of these patients have associated chronic kidney disease (CKD), which may require renal replacement therapy (RRT). Due to the complications associated with liver disease with coagulation disorders and tendencies towards spontaneous hypotension, there are significant problems associated to RRT, especially haemodialysis (HD). On the contrary, peritoneal dialysis (PD) offers several advantages over HD in cirrhotic patients (with or without ascites) thanks to better haemodynamic tolerance, as it is a continuous and slow technique. Furthermore, PD has a low rate of infection and bleeding.

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.

INTRODUCTION: Grafts from older donors or those in recipients with a greater body mass index (BMI) as compared with the donor may develop hyperfiltration syndrome that shortens renal graft survival. OBJECTIVES: To assess whether the differences in weight and BMI between donor and recipient correlated with renal function, proteinuria, or graft survival among recipients of grafts from expanded criteria donors. MATERIALS AND METHODS: We undertook a prospective, observational study in 180 recipients of grafts from expanded criteria donors performed between 1999 and 2006. All grafts had been biopsied previously for viability. The recipients underwent immunosuppression with basiliximab, late introduction of tacrolimus, mycophenolate mofetil and steroids. The study population was divided into three groups, depending on the tertile of the donor-to-recipient weight ratio (<1, n=64; 1-1.2, n=56; >1.2, n=60), and the donor-to-recipient BMI ratio (<0.97, n=59; 0.97-1.13, n=60; >1.13, n=60). The glomerular filtration rate was estimated from the modified diet in renal disease (MDRD) equation. RESULTS: The mean age of the donors was 63.54 years and of the recipients, 58.38 years. The proportion of male-to-female donors was 52:48 and recipients 57.8:42.2 (P=NS). No significant differences in overall graft survival were observed between the tertiles. There was a negative correlation between the donor-to-recipient weight ratio and serum creatinine value at 1 (P<.001), 3 (P=.013), and 12 months (P=.005) after transplantation, and a positive correlation with the MDRD at 1 month (P<.001). No relation was noted between weight and proteinuria at 1 (P=.25), 3 (P=.51), or 12 months (P=.90). The results were similar after analyzing the ratio of the BMI to creatinine, MDRD or proteinuria, as well as in cases of a female donor to a male recipient. CONCLUSIONS: Differences in weights between the donor and the recipient did not appear to affect graft survival or proteinuria among patients receiving grafts from expanded criteria donors, though it may be related to renal function during the early posttransplant stages.

INTRODUCTION: In patients who receive a kidney transplant from expanded criteria donors (ECDs), few studies are available concerning the relation between the clinical characteristics, pretransplant biopsies, and graft outcomes. AIM: To identify early clinical markers predicting worse graft survival in recipients of kidneys from ECDs. MATERIALS AND METHODS: Between 1999 and 2006, we performed a prospective, observational study in 180 recipients of kidney grafts from ECDs that had undergone a preoperative biopsy to evaluate viability. The patients received immunosuppression with basiliximab, late introduction of tacrolimus, mycophenolate mofetil, and steroids. Data were gathered on demographic and posttransplantation clinical characteristics at 1, 3, 6, and 9 months, including estimates of proteinuria and of the glomerular filtration rate using the Modification of Diet in Renal Disease (MDRD) formula. RESULTS: The mean age of the donors was 63.54 years and of the recipients, 58.38 years. A creatinine clearance below the median (40 mL/min, interquartile range 32-50 mL/min) in the first posttransplant year was significantly associated with worse death-censored graft survival (log-rank 14.22, P<.0001). A proteinuria value above the median (100 mg/24 h, interquartile range 40-275 mg/24 h) at 1 year posttransplant significantly reduced the death-censored graft survival (log-rank 14.3, P<.0001). Multivariate Cox analysis showed that a creatinine clearance<40 mL/min in the first year (hazards ratio [HR] 5.7, 95% Confidence Interval [CI] 1.62-20.37; P=.007) and proteinuria at 1 year greater tan 100 mg/24 h (HR 8.3, 95% CI 2.15-32.06; P=.002) were independent risk factors for death-censored graft loss after adjusting for donor age and acute rejection episodes. CONCLUSIONS: Limited renal function and/or low proteinuria at 1 year posttransplant were associated with worse kidney graft survival among recipients of kidneys from ECDS.

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.

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.

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.
