Abstract
INTRODUCTION Interprofessional consultations ("eConsults") can reduce healthcare utilization. However, the impact of eConsults on healthcare utilization remains poorly characterized among patients with headache. METHODS We performed a retrospective, 1:1 matched cohort study comparing patients evaluated for headache via eConsult request or in-person referral at the Mount Sinai Health System in New York. Groups were matched on clinical and demographic characteristics. Our primary outcome was one or more outpatient headache-related encounters in 6 months following referral date. Secondary outcomes included one or more all-cause outpatient neurology and headache-related emergency department (ED) encounters during the same period. We used univariable and multivariable logistic regression to model associations between independent variables and outcomes. RESULTS We identified 74 patients with headache eConsults who were matched to 74 patients with in-person referrals. Patients in the eConsult group were less likely to achieve the primary outcome (29.7% vs 62.2%, P < 0.0001) or have an all-cause outpatient neurology encounter (33.8% vs 79.7%, P < 0.0001) than patients in the comparison group. Both groups did not significantly differ by headache-related ED encounters. In multivariable analyses, patients in the eConsult group had significantly lower odds of having one or more headache-related or all-cause neurology encounters than patients in the comparison group (odds ratio (OR) 0.3, 95% confidence interval (CI) 0.1-0.6; OR 0.1, 95% CI 0.1-0.3, respectively). DISCUSSION In comparison to in-person referrals, eConsult requests for headache were associated with reduced likelihood of outpatient neurology encounters in the short-term but not with differential use of headache-related ED encounters. Larger-scale, prospective studies should validate our findings and assess patient outcomes.

Abstract
Introduction Understanding trends and associated factors in internet-based health care communication (IBHC) among cancer survivors is important for meeting patient needs because their reliance on telehealth is growing. We aimed to examine IBHC use among cancer survivors in the US. Methods We identified adult cancer survivors aged 18 to 64 (n = 8,029) and 65 or older (n = 11,087) from the National Health Interview Survey in 2011–2018. We calculated temporal trends of self-reported IBHC in the previous year (filled a prescription, scheduled a medical appointment, or communicated with a health care provider) and used multivariable logistic models to identify associated factors. Results Approximately 84% of survivors had been diagnosed 2 years or more before the survey. IBHC prevalence increased among cancer survivors aged 18 to 64, from 19.3% to 40.2%, and among those aged 65 or older, from 11.4% to 22.6%, from 2011 to 2018 (P for trend <.001). Among both age groups, lower educational attainment, lack of usual source of care, and current smoking were associated with less IBHC, whereas residing in the South or West, having 1 or more chronic conditions, and drinking any alcohol were associated with higher IBHC (all P < .05). Factors associated with less IBHC also included being non-Hispanic Black or Hispanic, lacking private insurance, and being 11 or more years postdiagnosis among survivors aged 18 to 64; among survivors aged 65 or older, factors were being an older age, not married, and non-US born (all P < .05). Conclusion IBHC among cancer survivors is common and increasing, with differences across sociodemographic and behavioral characteristics. As health care delivery continues adopting IBHC and other advanced telehealth techniques, disparities need to be addressed to ensure equitable access to care for all cancer survivors.

Randomized Trial of Empagliflozin in Nondiabetic Patients With Heart Failure and Reduced Ejection Fraction. J Am Coll Cardiol 2020; 77:243-255. [PMID: 33197559 DOI: 10.1016/j.jacc.2020.11.008] [Citation(s) in RCA: 254] [Impact Index Per Article: 63.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2020] [Revised: 11/05/2020] [Accepted: 11/06/2020] [Indexed: 01/04/2023]
Abstract
BACKGROUND Large clinical trials established the benefits of sodium-glucose cotransporter 2 inhibitors in patients with diabetes and with heart failure with reduced ejection fraction (HFrEF). The early and significant improvement in clinical outcomes is likely explained by effects beyond a reduction in hyperglycemia. OBJECTIVES The purpose of this study was to assess the effect of empagliflozin on left ventricular (LV) function and volumes, functional capacity, and quality of life (QoL) in nondiabetic HFrEF patients. METHODS In this double-blind, placebo-controlled trial, nondiabetic HFrEF patients (n = 84) were randomized to empagliflozin 10 mg daily or placebo for 6 months. The primary endpoint was change in LV end-diastolic and -systolic volume assessed by cardiac magnetic resonance. Secondary endpoints included changes in LV mass, LV ejection fraction, peak oxygen consumption in the cardiopulmonary exercise test, 6-min walk test, and quality of life. RESULTS Empagliflozin was associated with a significant reduction of LV end-diastolic volume (-25.1 ± 26.0 ml vs. -1.5 ± 25.4 ml for empagliflozin vs. placebo, respectively; p < 0.001) and LV end-systolic volume (-26.6 ± 20.5 ml vs. -0.5 ± 21.9 ml for empagliflozin vs. placebo; p < 0.001). Empagliflozin was associated with reductions in LV mass (-17.8 ± 31.9 g vs. 4.1 ± 13.4 g, for empagliflozin vs. placebo, respectively; p < 0.001) and LV sphericity, and improvements in LV ejection fraction (6.0 ± 4.2 vs. -0.1 ± 3.9; p < 0.001). Patients who received empagliflozin had significant improvements in peak O2 consumption (1.1 ± 2.6 ml/min/kg vs. -0.5 ± 1.9 ml/min/kg for empagliflozin vs. placebo, respectively; p = 0.017), oxygen uptake efficiency slope (111 ± 267 vs. -145 ± 318; p < 0.001), as well as in 6-min walk test (81 ± 64 m vs. -35 ± 68 m; p < 0.001) and quality of life (Kansas City Cardiomyopathy Questionnaire-12: 21 ± 18 vs. 2 ± 15; p < 0.001). CONCLUSIONS Empagliflozin administration to nondiabetic HFrEF patients significantly improves LV volumes, LV mass, LV systolic function, functional capacity, and quality of life when compared with placebo. Our observations strongly support a role for sodium-glucose cotransporter 2 inhibitors in the treatment of HFrEF patients independently of their glycemic status.

Repurposing erectile dysfunction drugs tadalafil and vardenafil to increase bone mass. Proc Natl Acad Sci U S A 2020; 117:14386-14394.

Abstract
We report that two widely-used drugs for erectile dysfunction, tadalafil and vardenafil, trigger bone gain in mice through a combination of anabolic and antiresorptive actions on the skeleton. Both drugs were found to enhance osteoblastic bone formation in vivo using a unique gene footprint and to inhibit osteoclast formation. The target enzyme, phosphodiesterase 5A (PDE5A), was found to be expressed in mouse and human bone as well as in specific brain regions, namely the locus coeruleus, raphe pallidus, and paraventricular nucleus of the hypothalamus. Localization of PDE5A in sympathetic neurons was confirmed by coimmunolabeling with dopamine β-hydroxylase, as well as by retrograde bone-brain tracing using a sympathetic nerve-specific pseudorabies virus, PRV152. Both drugs elicited an antianabolic sympathetic imprint in osteoblasts, but with net bone gain. Unlike in humans, in whom vardenafil is more potent than tadalafil, the relative potencies were reversed with respect to their osteoprotective actions in mice. Structural modeling revealed a higher binding energy of tadalafil to mouse PDE5A compared with vardenafil, due to steric clashes of vardenafil with a single methionine residue at position 806 in mouse PDE5A. Collectively, our findings suggest that a balance between peripheral and central actions of PDE5A inhibitors on bone formation together with their antiresorptive actions specify the osteoprotective action of PDE5A blockade.

Targeting weight loss interventions to reduce cardiovascular complications of type 2 diabetes: a machine learning-based post-hoc analysis of heterogeneous treatment effects in the Look AHEAD trial. Lancet Diabetes Endocrinol 2017; 5:808-815. [PMID: 28711469 PMCID: PMC5815373 DOI: 10.1016/s2213-8587(17)30176-6] [Citation(s) in RCA: 69] [Impact Index Per Article: 9.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2017] [Revised: 04/21/2017] [Accepted: 04/27/2017] [Indexed: 02/08/2023]
Abstract
BACKGROUND The Action for Health in Diabetes (Look AHEAD) trial investigated whether long-term cardiovascular disease morbidity and mortality could be reduced through a weight loss intervention among people with type 2 diabetes. Despite finding no significant reduction in cardiovascular events on average, it is possible that some subpopulations might have derived benefit. In this post-hoc analysis, we test the hypothesis that the overall neutral average treatment effect in the trial masked important heterogeneous treatment effects (HTEs) from intensive weight loss interventions. METHODS We used causal forest modelling, which identifies HTEs, using a random half of the trial data (the training set). We applied Cox proportional hazards models to test the potential HTEs on the remaining half of the data (the testing set). The analysis was deemed exempt from review by the Columbia University Institutional Review Board, Protocol ID# AAAO3003. FINDINGS Between Aug 22, 2001, and April 30, 2004, 5145 patients with type 2 diabetes were enrolled in the Look AHEAD randomised controlled trial, of whom 4901 were included in the The National Institute of Diabetes and Digestive and Kidney Diseases Repository and included in our analyses: 2450 for model development and 2451 in the testing dataset. Baseline HbA1c and self-reported general health distinguished participants who differentially benefited from the intervention. Cox models for the primary composite cardiovascular outcome revealed a number needed to treat of 28·9 to prevent 1 event over 9·6 years among participants with HbA1c 6·8% or higher, or both HbA1c less than 6·8% and Short Form Health Survey (SF-36) general health score of 48 or more (2101 [86%] of 2451 participants in the testing dataset; 167 [16%] of 1046 primary outcome events for intervention vs 205 [19%] of 1055 for control, absolute risk reduction of 3·46%, 95% CI 0·21-6·73%, p=0·038) By contrast, participants with HbA1c less than 6·8% and baseline SF-36 general health score of less than 48 (350 [14%] of 2451 participants in the testing data; 27 [16%] of 171 primary outcome events for intervention vs 15 [8%] of 179 primary outcome events for control) had an absolute risk increase of the primary outcome of 7·41% (0·60 to 14·22, p=0·003). INTERPRETATION Look AHEAD participants with moderately or poorly controlled diabetes (HbA1c 6·8% or higher) and subjects with well controlled diabetes (HbA1c less than 6·8%) and good self-reported health (85% of the overall study population) averted cardiovascular events from a behavioural intervention aimed at weight loss. However, 15% of participants with well controlled diabetes and poor self-reported general health experienced negative effects that rendered the overall study outcome neutral. HbA1c and a short questionnaire on general health might identify people with type 2 diabetes likely to derive benefit from an intensive lifestyle intervention aimed at weight loss. FUNDING None.

Abstract
OBJECTIVE Glargine and detemir insulin are the two most commonly prescribed basal insulin analogues for the ambulatory and inpatient management of diabetes. The efficacy and safety of basal insulin analogues in the hospital setting has not been established. METHODS This observational study compared differences in glycemic control and outcomes in non-intensive care unit patients with blood glucose (BG) >140 mg/dL who were treated with glargine or detemir, between January 1, 2012, and September 30, 2015, in two academic centers. RESULTS Among 6,245 medical and surgical patients with hyperglycemia, 5,749 received one or more doses of glargine, and 496 patients received detemir during the hospital stay. There were no differences in the mean daily BG (glargine, 182 ± 46 mg/dL vs. detemir, 180 ± 44 mg/dL; P = .70). There were no differences in mortality, hospital complications, or re-admissions between groups (all, P>.05). After adjusting for potential confounders, there was no statistically significant difference in hypoglycemia rates between treatment groups. Patients treated with detemir required higher total daily basal insulin doses (0.27 ± 0.16 units/kg/day vs. 0.22 ± 0.15 units/kg/day; P<.001). Glargine-treated patients had statistically longer length of stay; however, this difference may not be clinically relevant (6.8 ± 7.4 days vs. 6.0 ± 6.3 days; P<.001). CONCLUSION Our study indicates that treatment with glargine and detemir results in similar inpatient glycemic control in general medicine and surgery patients. Detemir treatment was associated with higher daily basal insulin dose and number of injections. A prospective randomized study is needed to confirm these findings. ABBREVIATIONS BG = blood glucose BMI = body mass index CI = confidence interval eGFR = estimated glomerular filtration rate HbA1c = glycated hemoglobin ICD-9 = International Classification of Diseases, ninth revision ICU = intensive care unit IQR = interquartile range LOS = length-of-stay OR = odd ratio.

Abstract
Type 2 diabetes (T2D) is a heterogeneous complex disease affecting more than 29 million Americans alone with a rising prevalence trending toward steady increases in the coming decades. Thus, there is a pressing clinical need to improve early prevention and clinical management of T2D and its complications. Clinicians have understood that patients who carry the T2D diagnosis have a variety of phenotypes and susceptibilities to diabetes-related complications. We used a precision medicine approach to characterize the complexity of T2D patient populations based on high-dimensional electronic medical records (EMRs) and genotype data from 11,210 individuals. We successfully identified three distinct subgroups of T2D from topology-based patient-patient networks. Subtype 1 was characterized by T2D complications diabetic nephropathy and diabetic retinopathy; subtype 2 was enriched for cancer malignancy and cardiovascular diseases; and subtype 3 was associated most strongly with cardiovascular diseases, neurological diseases, allergies, and HIV infections. We performed a genetic association analysis of the emergent T2D subtypes to identify subtype-specific genetic markers and identified 1279, 1227, and 1338 single-nucleotide polymorphisms (SNPs) that mapped to 425, 322, and 437 unique genes specific to subtypes 1, 2, and 3, respectively. By assessing the human disease-SNP association for each subtype, the enriched phenotypes and biological functions at the gene level for each subtype matched with the disease comorbidities and clinical differences that we identified through EMRs. Our approach demonstrates the utility of applying the precision medicine paradigm in T2D and the promise of extending the approach to the study of other complex, multifactorial diseases.

Abstract
OBJECTIVE To establish the prevalence of reliable self-monitored blood glucose (r-SMBG) data at office visits for diabetes and to determine whether r-SMBG is associated with changes in glycemic control and other clinical parameters. METHODS We conducted a chart review of 500 patients followed in an Endocrinology Faculty/Commercial Insurance Practice (FP) or a Managed Medicare/Medicaid Diabetes Clinic (MDC). Follow-up visits for patients with type 1 or type 2 diabetes from January 1, 2012 to June 30, 2012 were analyzed for anthropometric data, creatinine (Cr), glomerular filtration rate (GFR), low-density lipoprotein cholesterol (LDL-C), medications, hemoglobin A1C (A1C), change in A1C from the previous visit (ΔA1C), and availability of r-SMBG data at the visit. RESULTS Our sample was composed of 215 MDC patients (43%) and 285 FP patients (57%). Overall, 151 patients (30%) provided r-SMBG data at their visit, with no difference between MDC or FP patients. Mean A1C at MDC was 9.1%, while mean A1C at FP was 7.9% (P<.001). MDC patients with A1C >8.0% demonstrated an A1C reduction of 1.2% if they provided r-SMBG, compared to an increase of 0.1% for MDC patients who did not (P<.05). Providing r-SMBG did not affect A1C in FP patients in any A1C range. CONCLUSION Only a minority of diabetes patients, mostly insulin-treated, made r-SMBG data available to their providers. Insulin-requiring Managed Medicare/Medicaid patients with poorly controlled diabetes had an A1c reduction associated with r-SMBG. Prospective studies are needed to determine whether this patient population may be more likely to benefit from r-SMBG at their visits.

Patient reported outcome measures of pain intensity: Do they tell us what we need to know? Scand J Pain 2016; 11:73-76.

Abstract
Abstract
Objective
To determine the relationship between chronic pain patients’ responses to self-report measures of pain intensity, and self-reported strategies when completing such measures.
Participants
Ambulatory outpatients suffering from one of the following chronic pain conditions: painful HIV neuropathy, painful diabetic neuropathy, chronic Low-Back Pain.
Method
As part of a previously reported study using qualitative methods, participants completed standard pain intensity questionnaires as well as a measure of pain related disturbances in activities of daily living. In the previous study, participants’ responses during a focus group were then used to identify their strategies and beliefs about their approach to completing the questionnaires. Among the beliefs were: (1) difficulties averaging pain over different time periods (i.e., “what was your average pain during the last 24h” versus “what was your average pain during the last 2 weeks”); (2) difficulty in comparing pain from different etiologies; (3) difficulties in reporting sensations of pain in a manner unaffected by issues and situations secondary to the pain experience, such as difficulties in activities of daily living. In the present paper we use ANOVA (analysis of variance) and partial correlation to determine whether the qualitatively derived perceptions are reflected in the quantitative pain intensity scores.
Results
Participants’ belief that it was difficult to “average” pain intensity over different time periods was supported. The data do not support their belief that pain intensity scores are affected by other factors: their specific pain diagnosis, and the extent to which pain interfered with their activities of daily living.
Conclusions
(1) Patients tend to report different levels of pain intensity when asked to report their pain over different periods; (2) insofar as it can be said to exist, the relationship between measures of intensity and interference with activities of daily living is minimal; (3) participants tend to report similar levels of pain intensity, irrespective of etiology.
Implications
(1) Chronic pain patients’ elicited beliefs and strategies concerning how they complete pain intensity questionnaires are sometimes, but not invariably, reflected in their responses to these measures. Thus, purely qualitative methodologies alone cannot provide completely reliable information and point to the need to use a “mixed methods” approach combining both qualitative and quantitative data; (2) the lack of association between pain intensity measures and interference with activities of daily living, as well as relative insensitivity to different etiologies underlines the problem in relying on pain intensity measures as the primary means of evaluating the success of a treatment, either for pain management or in clinical research.

Abstract
OBJECTIVE Posttransplantation diabetes (PTDM) is a common occurrence after solid-organ transplantation and is associated with increased morbidity, mortality, and health care costs. There is a limited number of studies addressing strategies for hyperglycemia management in this population, with a few articles emerging recently. METHODS We performed a PubMed search of studies published in English addressing hyperglycemia management of PTDM/new-onset diabetes after transplant (NODAT). Relevant cited articles were also retrieved. RESULTS Most of the 25 publications eligible for review were retrospective studies. Insulin therapy during the early posttransplantation period showed promise in preventing PTDM development. Thiazolidinediones have been mostly shown to exert glycemic control in retrospective studies, at the expense of weight gain and fluid retention. Evidence with metformin, sulfonylureas, and meglitinides is very limited. Incretins have shown promising results in small prospective studies using sitagliptin, linaglitpin, and vildagliptin and a case series using liraglutide. CONCLUSION Prospective randomized studies assessing the management of hyperglycemia in PTDM are urgently needed. In the meantime, clinicians need to be aware of the high risk of PTDM and associated complications and current concepts in management.

Abstract
Pruritus is a risk factor for self-injury behavior (SIB) in sensory polyneuropathies. Although diabetes patients have elevated risk for pruritus, there are no reports of SIB in diabetic neuropathy. We present the case of a diabetes patient with neuropathy, whose pruritus induced SIB, resulted in partial amputation of a toe.

Abstract
AIM An online diabetes course for medical residents led to lower patient blood glucose, but also increased hypoglycaemia despite improved trainee confidence and knowledge. Based on these findings, we determined whether an optimized educational intervention delivered to hospitalists (corresponding to an Acute Physician or Specialist in Acute Hospital Medicine in the UK) improved inpatient glycaemia without concomitant hypoglycaemia. METHODS All 22 hospitalists at an academic medical centre were asked to participate in an online curriculum on the management of inpatient dysglycaemia in autumn 2009 and a refresher course in spring 2010. RESULTS All hospitalists completed the initial intervention. Median event blood glucose decreased from 9.3 mmol/l (168 mg/dl) pre-intervention to 7.8 mmol/l (141 mg/dl) post-intervention and 8.5 mmol/l (153 mg/dl) post-refresher (P < 0.001 for both). Hospitalizations categorized as hyperglycaemia decreased from 83.3 to 55.6% (P = 0.014), with a trend towards euglycaemia (10-28.9%, P = 0.08) and no change in hypoglycaemia. Hyperglycaemic patient-days decreased from 72.0 to 57.3% (P = 0.004), with greater target glycaemia (27.3-39.4%, P = 0.016) and no change in hypoglycaemia. CONCLUSIONS An optimized online educational intervention delivered to hospitalists yielded significant improvements in inpatient glycaemia without increased hypoglycaemia.

BACKGROUND This study evaluated whether education and use of the advanced meter features of the CONTOUR(®) (Bayer HealthCare LLC, Diabetes Care, Tarrytown, NY) blood glucose monitoring system (BGMS) affect the frequency and pattern of blood glucose testing in insulin-using subjects with diabetes who routinely perform self-monitoring of blood glucose (SMBG). SUBJECTS AND METHODS Insulin-using subjects with type 1 or type 2 diabetes were enrolled in this 6-month, multicenter, prospective study and randomized to one of two groups. The basic meter features group (BMF group) received basic instruction in the use of the BGMS, whereas the advanced meter features group (AMF group) also received training in the use of advanced features, including the meal marker and audible reminder, and were instructed to use these features. Both groups received education on the importance of postprandial testing. RESULTS The AMF group (n=105) had significantly greater average weekly postprandial blood glucose testing than the BMF group (n=106) at each follow-up visit (P<0.001) and significantly increased the frequency of paired blood glucose testing (P<0.001) as well. In both groups, glycated hemoglobin decreased significantly as postprandial testing frequency increased (P<0.05). Subject reports indicated that use of advanced features made postmeal SMBG considerably easier to remember, helped them better understand how to make decisions on their own, and increased their confidence in meal choices. CONCLUSIONS Study findings showed that advanced features of the CONTOUR BGMS increased structured testing as measured by postprandial and paired SMBG and were perceived as useful by patients.

Abstract
BACKGROUND Inpatient dysglycemia is associated with increased morbidity, mortality and cost. Medical education must not only address knowledge gaps, but also improve clinical care. METHODS All 129 medicine residents at a large academic medical center were offered a case-based online curriculum on the management of inpatient dysglycemia in the fall of 2009. First-year residents took a 3-h course with 10 modules. Second and third-year residents, who had been educated the prior year, underwent abbreviated training. All residents were offered a 20-min refresher course in the spring of 2009. We assessed resident knowledge, resident confidence, and patient glycemia on two teaching wards before and after the initial intervention, as well as after the refresher course. RESULTS A total of 117 residents (91%) completed the initial training; 299 analyzed admissions generated 11, 089 blood glucose values and 4799 event blood glucose values. Admissions with target glycemia increased from 19.4% to 33.0% (P = 0.035) by the end of the curriculum. There was a strong downward trend in hyperglycemia from 22.4% to 11.3% (P = 0.055) without increased hypoglycemia. Confidence and knowledge increased significantly among first-time and repeat participants. Residents rated the intervention as highly relevant to their practice and technologically well implemented. CONCLUSION Optimization of an online curriculum covering the management of inpatient glycemia over the course of 2 years led to significantly more admissions in the target glycemia range. Given its scalability, modularity and applicability, this web-based educational intervention may become the standard curriculum for the management of inpatient glycemia.

Diabetes, glucose control, glucose lowering medications, and cancer risk: a 10-year population-based historical cohort. BMC Cancer 2012; 12:364. [PMID: 22917080 PMCID: PMC3488338 DOI: 10.1186/1471-2407-12-364] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2012] [Accepted: 08/07/2012] [Indexed: 12/13/2022] Open
Abstract
Background Both diabetes and glucose-lowering medications have been associated with an increased risk of cancer incidence. This study will compare cancer incidence rates in individuals with and without diabetes; and will investigate, in individuals with diabetes, an association between glucose control and cancer incidence; and between the use of specific glucose-lowering medications, as well as no drug exposure, and cancer incidence. Methods/design This is a population based historical cohort study of all individuals aged 21 years or older (about 2,300,000) who were insured by Clalit Health Services, the largest health maintenance organization in Israel during a ten-year study period. Four study groups will be established according to the status of diabetes and cancer at study entry, Jan 1, 2002: cancer free, diabetes free; cancer free, diabetes prevalent; cancer prevalent, diabetes free; and cancer prevalent, diabetes prevalent. Individuals without diabetes at study entry will be followed for diabetes incidence, and all four groups will be followed for specific cancer incidence, including second primary neoplasms. Glucose control will be assessed by HbA1c and by fasting plasma glucose levels. Time dependent regression models for cancer incidence will account for glucose-lowering medications as they are added and changed over the follow-up period. A large number of demographic and clinical variables will be considered, including: age, gender, BMI, smoking status, concomitant medications, glucose control (assessed by HbA1c and by fasting plasma glucose) and cancer screening tests. Discussion Strengths of this study include the large population; high quality comprehensive data; comparison to individuals without diabetes, and to those with diabetes but not treated with glucose-lowering medications; and the extensive range of variables available for analysis. The great increases in diabetes prevalence and in treatment options render this study particularly relevant and timely. The Israeli national healthcare system, characterized by high standard and uniform healthcare, offers an advantageous environment for its conduct.

Abstract
We reviewed diabetes apps for Android smartphones. We compiled a list of free and paid apps in April 2011 by searching the Android Market for apps which could track self-monitoring of blood glucose (SMBG), diabetes medications or calculate prandial insulin dosages. Two reviewers independently evaluated six features per app, using a five-point Likert scale. The sum of the six ratings was the composite usability score, and the mean score of an app's features was the average usability score. Of the 80 Android diabetes apps identified, 42 unique apps were eligible for the study. SMBG recording was present in 36 (86%) of the apps, a tool to track insulin or oral diabetic medications was found in 19 (45%) apps, and a prandial insulin dose calculator existed for 11 (26%) apps. Eighteen apps were free of charge and the other 24 apps had a mean purchase price of $2.86 (range 0.99-6.99). The mean composite usability score was 11.3 out of a possible 30. The mean average usability score was 3.0 out of a possible 5.0. Only four of the 42 apps had a composite usability score above 20 and none offered direct data input from glucometers, suggesting that few provided a comprehensive method of diabetes management. The apps Glucool Diabetes, OnTrack Diabetes, Dbees and Track3 Diabetes Planner were the highest rated. Clinicians may find it useful to recommend these apps.

Abstract
The aim of this paper was to report the case of type 2 diabetes and significant insulin resistance that improved dramatically after removal of a pheochromocytoma in a liver transplant recipient , and to provide a review of the relevant literature. We describe the clinical presentation, diagnostic results and management of the patient. In addition, we performed a PubMed search for related English language articles, to provide an overview of the pertinent literature. A 53 year old woman with a history of an orthotopic liver transplantation and insulin-requiring type 2 diabetes was admitted to the hospital with fever, diaphoresis, tachycardia and hypertension. A pheochromocytoma was diagnosed and removed. The patient subsequently developed hypoglycemia and required no further insulin therapy. Pheochromocytomas have been described to lead to hyperglycemia and diabetes, due to the suppression of insulin release and increased insulin resistance. Furthermore, a review of the literature revealed only 3 other reported cases of pheochromocytomas in organ transplant recipients. None of these pheochromocytomas were believed to have occurred de novo after transplantation. This is the first report of a pheochromocytoma in a liver transplant recipient and possibly the first case of a de novo pheochromocytoma in any organ transplant recipient. Moreover, this case showcases pheochromocytomas as a rare cause of diabetes mellitus.

Abstract
OBJECTIVE To determine whether an educational intervention for medical house staff improves blood glucose (BG) in hospitalized patients. RESEARCH DESIGN AND METHODS All 116 medicine residents at an academic medical center were assigned to online or classroom training on inpatient dysglycemia in fall 2008. Both groups were offered an online refresher course in spring 2009 addressing gaps in clinical practice identified on chart review. We assessed event BG, the first BG of any 3-h period, on two teaching wards. RESULTS A total of 108 residents (93.1%) completed the initial training. The primary outcome, median event BG, decreased from 152 mg/dL in August 2008 to 139 mg/dL in December 2008 (P < 0.0001). Prevalence of event BG >200 mg/dL decreased from 25.5 to 22.7% (P = 0.0207), at the expense of more event BGs <70 mg/dL (2.0-3.9%, P = 0.0124). CONCLUSIONS A curriculum for medicine residents on inpatient glycemia led to lower inpatient BG.

Abstract
BACKGROUND Recent evidence supports the protective effects of n-3 (omega-3) fatty acids (n-3 FAs), such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), on vascular function. OBJECTIVE We investigated the effects of EPA and DHA on postprandial vascular function in subjects with type 2 diabetes mellitus. DESIGN In a double-blind, placebo-controlled, randomized, crossover manner, 34 subjects with type 2 diabetes mellitus received daily either 2 g purified EPA/DHA (termed n-3 FAs) or olive oil (placebo) for 6 wk. At the end of this period, we measured macrovascular (brachial ultrasound of flow-mediated dilatation; FMD) and microvascular [laser-Doppler measurements of reactive hyperemia (RH) of the hand] function at fasting and 2, 4, and 6 h after a high-fat meal (600 kcal, 21 g protein, 41 g carbohydrates, 40 g fat). RESULTS Fasting vascular function remained unchanged after n-3 FAs and placebo. Postprandial FMD decreased from fasting after placebo, with a maximum decrease (38%) at 4 h-an effect that was significantly reduced (P = 0.03 for time x treatment interaction) by n-3 FA supplementation (maximum decrease in FMD was at 4 h: 13%). RH remained unchanged after placebo, whereas it improved significantly (P = 0.04 for time x treatment interaction) after n-3 FA supplementation (maximum increase was at 2 h: 27%). CONCLUSIONS In subjects with type 2 diabetes mellitus, 6 wk of supplementation with n-3 FAs reduced the postprandial decrease in macrovascular function relative to placebo. Moreover, n-3 FA supplementation improved postprandial microvascular function. These observations suggest a protective vascular effect of n-3 FAs.

Abstract
Dietary supplements and nutraceuticals are commonly used by men with erectile dysfunction, decreased libido, BPH, and concerns about developing prostate cancer. Many preparations do not contain the advertised dosages of the active ingredient or are contaminated. Dietary supplements and nutraceuticals, particularly those addressing erectile dysfunction and libido, need to undergo rigorous testing before they can be wholeheartedly recommended.

Abstract
Glucocorticoids have been the main agents for preventing organ rejection,but unfortunately they possess serious side effects. Newer immunosuppressive agents have therefore been introduced to overcome these effects and have had a dramatic impact on reducing the incidence of organ rejection, enhancing donor organ acceptance, and hence patient survival posttransplantation. However, calcineurin inhibitors (CIs), such as cyclosporine and tacrolimus, also have serious effects causing rapid and severe bone loss in animal models and humans. The mechanism accounting for this action is unclear at present, but the role of T lymphocyte action via RANKL seems to be of essence in triggering bone loss. The mechanism is complex and in vitro studies often produce results that are opposite to those seen in vivo. In addition to acute, rapid, and severe bone loss (ARSBL), the clinical picture shows an extremely high incidence of fractures at all sites, and depends upon the organ transplanted, preexisting bone disease, interval before transplantation, and the dose and duration of multiple immunosuppressive drugs. Other immune-modifying drugs, such as azathioprine, mycophenolate mofetil, and sirolimus, which are used in conjunction with glucocorticoids and CIs have not been shown to promote bone loss experimentally or clinically. With the exception of glucocorticoids, all of the agents discussed here demand further investigation with regard to their effects on bone health in the clinical setting.

Abstract
Diaryl tellurides effectively protect against peroxynitrite-mediated oxidation of dihydrorhodamine 123 (DHR), hydroxylation of benzoate, and nitration of 4-hydroxyphenylacetate (HPA). Bis(4-aminophenyl) telluride offered the most efficient protection against oxidation of DHR induced by peroxynitrite. Protection by this compound was approximately 3 times more effective than that afforded by its selenium analog, bis(4-aminophenyl) selenide, and 11 times more effective than selenomethionine. When peroxynitrite was infused to maintain a steady-state concentration, bis(4-aminophenyl) telluride in the presence of GSH, but neither bis(4-aminophenyl) telluride nor GSH alone, effectively inhibited the peroxynitrite-mediated hydroxylation of benzoate. The inhibition of nitration was most pronounced using bis(4-hydroxyphenyl) telluride, and this compound was ca. 3 times more effective than selenomethionine. Bis(4-aminophenyl) telluride also protected proteins in lysates from human skin fibroblasts from peroxynitrite-mediated nitration of tyrosine residues more effectively than selenomethionine. These data establish a potential biological or pharmacological role of organotellurium compounds in the defense against peroxynitrite.
