Diabetes and erectile dysfunction: The relationships with health literacy, treatment adherence, unrealistic optimism, and glycaemic control

Purpose: The aim of this study was to evaluate the relationships between health literacy, unrealistic optimism, and adherence to glycometabolic disease management related to erectile dysfunction (ED) in male patients with type 2 diabetes (T2D) or preDM. Materials and methods: This prospective observational study enroled 167 consecutive patients with T2D and ED. All patients underwent the following examinations: (a) medical history collection; (b) Body Mass Index (BMI) determination; (c) hormonal and biochemical assessment; (d) duration of T2D, complications and treatment; (e) International Index of Erectile Function-5 questionnaire to assess ED; and (f) validated questionnaire to evaluate health literacy, unrealistic optimism, and treatment adherence. Results: Overall, mean age was 62.5 ± 9.4 years (range: 20-75) and mean BMI was 28.4 ± 4.8 kg/m2 (range: 18.4-46.6). The mean IIEF-5 score was 15.4 ± 5.2 (range: 5-25). The majority of patients showed high health literacy. However, low health literacy was found in patients with higher IIEF-5 scores and high BMI. Unrealistic optimism was low in most patients. Higher adherence to treatment was found in patients who reported regular physical activity, who followed a diet, and in patients with a family history of T2D. Regarding anti-diabetic treatment, patients treated with insulin showed higher health literacy than patients not treated with other medications, whereas higher adherence was found in patients using SGLT2-i. Conclusions: This study highlighted the close relationship between metabolic compensation, BMI, ED, and psychological attitudes, including health literacy and unrealistic optimism

Changes in bone turnover markers in patients without bone metastases receiving immune checkpoint inhibitors: An exploratory analysis

Immune checkpoint inhibitors (ICIs) has revolutionized the treatment of different advanced solid tumors, but most patients develop severe immune-related adverse events (irAEs). Although a bi-directional crosstalk between bone and immune systems is widely described, the effect of ICIs on the skeleton is poorly investigated. Here, we analyze the changes in plasma levels of type I collagen C-terminal telopeptide (CTX-I) and N-terminal propeptide of type I procollagen (PINP), reference makers of bone turnover, in patients treated with ICIs and their associ-ation with clinical outcome.A series of 44 patients affected by advanced non-small cell lung cancer or renal cell carcinoma, without bone metastases, and treated with ICIs as monotherapy were enrolled. CTX-I and PINP plasma levels were assessed at baseline and after 3 months of ICIs treatment by ELISA kits.A significant increase of CTX-I with a concomitant decreasing trend towards the reduction of PINP was observed after 3 months of treatment. Intriguingly, CTX-I increase was associated with poor prognosis in terms of treatment response and survival. These data suggest a direct relationship between ICIs treatment, increased osteoclast activity and potential fracture risk.Overall, this study reveals that ICIs may act as triggers for skeletal events, and if confirmed in larger pro-spective studies, it would identify a new class of skeletal-related irAEs

Antibodies to post-translationally modified insulin as a novel biomarker for prediction of type 1 diabetes in children

Aims/hypothesis We have shown that autoimmunity to insulin in type 1 diabetes may result from neoepitopes induced by oxidative post-translational modifications (oxPTM). Antibodies specific to oxPTM-insulin (oxPTM-INS-Ab) are present in most newly diagnosed individuals with type 1 diabetes and are more common than autoantibodies to native insulin. In this study, we investigated whether oxPTM-INS-Ab are present before clinical onset of type 1 diabetes, and evaluated the ability of oxPTM-INS-Ab to identify children progressing to type 1 diabetes. Methods We used serum samples collected longitudinally from the All Babies in Southeast Sweden (ABIS) cohort tested for the gold standard islet autoantibodies to insulin (IAA), GAD (GADA), tyrosine phosphatase 2 (IA-2A) and zinc transporter 8 (ZnT8A). We studied 23 children who progressed to type 1 diabetes (progr-T1D) and 63 children who did not progress to type 1 diabetes (NP) after a median follow-up of 10.8 years (interquartile range 7.7-12.8). Of the latter group, 32 were positive for one or more islet autoantibodies (NP-AAB(+)). oxPTM-INS-Ab to insulinmodified by (OH)-O-center dot or HOCl were measured by our developed ELISA platform. Results Antibodies to at least one oxPTM-INS were present in 91.3% of progr-T1D children. oxPTM-INS-Ab co-existed with GADA, IA-2A, IAA or ZnT8A in 65.2%, 56.5%, 38.9% and 33.3% progr-T1D children, respectively. In addition, oxPTM-INS-Ab were present in 17.4%, 26.1%, 38.9% and 41.6% of progr-T1D children who were negative for GADA, IA-2A, IAA and ZnT8A, respectively. (OH)-O-center dot-INS-Ab were more common in progr-T1D children than in NP-AAB+ children (82.6% vs 19%; p amp;lt; 0.001) and allowed discrimination between progr-T1D and NP-AAB(+) children with 74% sensitivity and 91% specificity. None of the NP-AAB(-) children were positive for oxPTM-INS-Ab. Conclusions/interpretation oxPTM-INS-Ab are present before the clinical onset of type 1 diabetes and can identify children progressing to type 1 diabetes.Funding Agencies|EFSD/JDRF/Lilly European Programme [3-PAR-2016-277-A-N]; JDRF innovative grant [INO-2015-78-S-B]; Swedish Research Council [K2005-72X-11242-11A, K2008-69X-20826-01-4]; Swedish Child Diabetes Foundation (Barndiabetesfonden); JDRF Wallenberg Foundation [K 98-99D-12813-01A]; Medical Research Council of Southeast Sweden (FORSS); Swedish Council for Working Life and Social Research [FAS2004-1775]</p

The Alliance of Mesenchymal Stem Cells, Bone, and Diabetes

Bone fragility has emerged as a new complication of diabetes. Several mechanisms in diabetes may influence bone homeostasis by impairing the action between osteoblasts, osteoclasts, and osteocytes and/or changing the structural properties of the bone tissue. Some of these mechanisms can potentially alter the fate of mesenchymal stem cells, the initial precursor of the osteoblast. In this review, we describe the main factors that impair bone health in diabetic patients and their clinical impact

Serum 25-OH Vitamin D in relation to Bone Mineral Density and Bone Turnover

It is unclear which vitamin D status is optimal for bone health. In this study, we aimed to assess cutoffs of 25-hydroxyvitamin D (25OHD) derived by the literature (20, 25, or 30 ng/mL) in relation to bone turnover and bone mineral density (BMD). Serum 25OHD, PTH, osteocalcin, bone alkaline phosphatase, and C-telopeptide were measured in 274 consecutive postmenopausal women. BMD of the lumbar spine (L1-L4) and of femoral neck were also evaluated. 50 patients had normal BMD, while 124 had osteopenia and 100 had osteoporosis. 37.6%, 56.2%, and 70.8% subjects had serum 25OHD lower than 20, 25, or 30 ng/mL, respectively. No differences in bone turnover markers were found when comparing patients with low 25OHD defined according to the different cutoffs. However, a cutoff of 25 ng/mL appeared to differentiate better than a cutoff of 30 ng/mL in those subjects with reduced femoral neck BMD. The PTH plateau occurred at 25OHD levels of 26-30 ng/mL. In conclusion, vitamin D deficiency is common in Sicilian postmenopausal women and it may be associated with low BMD and increased bone turnover markers. Further studies are needed to better define the right cutoff for normal vitamin D levels in postmenopausal women
