RESUMO
Background: A considerable amount of research funding goes to diabetes management strategies to improve therapeutic goals and reduce the burden of diabetes. A vast amount of the budget is wasted due to unnecessary studies. A scoping review is a pivotal study to overview the available evidence and avoid research waste. In this review, we will try to find out the scope of available studies on diabetes management interventions, identify associated research gaps, and prioritize future studies. Method: We will carry out a study using Arksey and O'Malley's scoping review framework. We will search the Scopus and PubMed databases from 01/01/2015 till 01/01/2020. Only original articles related to pharmacological and non-pharmacological management interventions will be included. These interventional studies should be conducted on the Iranian population. After data extraction, a descriptive data analysis will be used to present information in different charts or tables. We will evaluate related published articles based on their document type, level of evidence, type of diabetes, subject area, interventions types, main findings and outcomes. Discussion: This study represents the first attempt to sum up available studies related to diabetes management interventions performed in Iran. The results of this study will be useful for all the stakeholders and policy-makers involved in diabetes research. It can help clinicians to be informed about studies on management interventions and can guide scientists eager to diabetes research to choose their future research plans based on diabetes research requirements and gaps.
RESUMO
OBJECTIVE: The following report describes the evaluation of the ISPAD Science School for Physicians (ISSP) and for Healthcare Professionals (ISSHP) in terms of their efficiency and success. METHODS: All past attendees from 2000-2019 ISSP and 2004-2019 ISSHP programs were invited to respond to an online survey to assess perceived outcomes of the programs on career development, scientific enhancement, scientific networking, and social opportunities. RESULTS: One-third of the past ISSP (129/428), and approximately 43% of the past ISSHP attendees (105/245) responded to the surveys. Most of ISSP attendees reported that the programs supported their career (82%) by helping to achieve a research position (59%), being engaged with diabetes care (68%) or research (63%) or starting a research fellowship (59%). Responders indicated that ISSP was effective in increasing interest in diabetes research (87%) and enhancing the number (66%) and quality (83%) of scientific productions, and promotion of international collaborations (86%). After the ISSP, 34% of responders received research grants. From the first round of the ISSHP survey (2004-2013), responders reported have improved knowledge (60%), gained more confidence in research (69%), undertaken a research project (63%), and achieved a higher academic degree (27%). From the second round (2014-2019), participants indicated that the program was valuable/useful in workplace (94%) through understanding (89%) and conducting (68%) research and establishing communication from other participants (64%) or from faculty (42%). After the ISSHP, 17% had received awards. CONCLUSIONS: From the participants' viewpoint, both programs were effective in improving engagement with diabetes research, supporting career opportunities, increasing scientific skills, and enhancing networking and research activities.

OBJECTIVES: Measurement of lipoprotein(a) [Lp(a)] is used in risk assessment of atherosclerotic cardiovascular disease (ASCVD). The aim of the current study was to evaluate performance characteristic of five different Lp(a) assays using the cobas c501 (Roche Diagnostics) analyzer. DESIGN AND METHODS: Lp(a) was measured using five Lp(a) assays (Diazyme, Kamiya, MedTest, Randox, and Roche) configured to mg/dL units. Assays from Diazyme and Kamiya were also configured using nmol/L units in separate experiments. Studies included sensitivity, imprecision, linearity, method comparison, and evaluation of healthy subjects. Imprecision (intra-day, 20 replicates; inter-day, duplicates twice daily for five days) and linearity were evaluated using patient pools. Linearity assessed a minimum of five patient splits spanning the analytical measurement range (AMR). Method comparison used 80 residual serum samples. Specimens from 120 self-reported healthy subjects (61 females / 59 males) were also tested. Method comparison for two assays in nmol/L units was conducted using 96 residual serum samples. RESULTS: Assay sensitivities met all manufacturer claims. Imprecision studies demonstrated %CVs ranging from 2.5 to 5.2% for the low pool (average concentration from 7.3 to 12.4 âmg/dL); high pool %CVs ranged from 0.8 to 3.0% (average concentrations from 31.5-50.2 âmg/dL). Linearity was confirmed for all assays. Variation in accuracy was observed when comparing results to an all method average. Lp(a) results were higher in females versus males in self-reported healthy subjects. CONCLUSIONS: All assays performed according to manufacturer described performance characteristics, although differences were observed across Lp(a) assays tested when compared to an all method average.
RESUMO
BACKGROUND: Diabetes mellitus (DM) is one of the most prevalent metabolic diseases in the UAE. During the last two decades, the United Arab Emirates (UAE) has experienced tremendous development in all fields including DM research. The present study sheds light on the growth in DM research in UAE and represents a guide for DM researchers to create more focused future directions in DM research. OBJECTIVES: The main objective of the present study is to investigate and document the changes that occurred in DM research in the UAE over the last two decades. METHODS: Several research databases were reviewed and all the articles that involved any form of DM research within the UAE were selected. Inclusion criteria were: (i) Research studies related to DM and conducted by institutions based in UAE (ii) Research studies related to DM and conducted in the population of UAE and (iii) Research articles related to DM and the authors (principal investigators or co-investigators) are from UAE. RESULTS: Between the years of 1996 and 2000, there was an average of 6.4 articles about DM being published per year. This pattern changed dramatically between years 2011 to 2015 where an average of 22.8 articles were being published. In addition, a significant increase was noticed in the year 2015 with 42 articles published per year. It was also found that 46.8% articles involved clinical study, 12.1% were basic research, 17.5% cross-sectional studies, 8.91% reviews, 8.2% were cohort and all the other types of research represented about 5.58%. CONCLUSION: Significant progress has been noticed in DM research in the UAE during the last two decades. Based on the findings of the present study, more focus should be given to the case reports and clinical trials.

INTRODUCTION: IDRS is based on four simple parameters derived from known risk factors for diabetes; two modifiable risk factors (waist circumference and physical inactivity) and two non-modifiable risk factors (age and family history of diabetes), which may be amenable to intervention. The present study has been planned as the region specific validation is important before it can be used for screening in this part of the country. AIMS: The aim of the present study was to validate MDRF-IDRS for screening of diabetes mellitus among adult population of urban field practice area, IGMC, Shimla, Himachal Pradesh, India. METHODS: The present community based cross sectional study was conducted among 417 adults fulfilling the eligibility criteria using a two stage sampling design. RESULTS: In the present study IDRS value ≥70 had an optimum sensitivity of 61.33% and specificity of 56.14% for detecting undiagnosed type 2 diabetes in the community. At an IDRS score of ≥70, the PPV was 23.47%, NPV as 86.88%, the diagnostic accuracy as 57.07%, LR for positive test as 1.398, LR for negative test as 0.69 and Youden's index as 0.17. However Youden's index was 0.19 at a cut of ≥60 i.e. higher than what was at ≥70. Higher IDRS scores increased the specificity but the sensitivity dramatically decreased. Conversely, lower IDRS values increased the sensitivity but the specificity drastically decreased. Area under the curve = 0.630 and a P value < 0.001. CONCLUSIONS: MDRF IDRS is user friendly screening tool but the criteria of including the parameter of physical activity for the calculation of the risk score needs to be clearly defined. In the present study the maximum sensitivity of 100% was seen at a cut off of ≥30. Hence we would recommend that all those in the medium and high risk group should be screened for type 2 Diabetes.
RESUMO
PURPOSE OF REVIEW: This review seeks to characterize emerging concepts related to disease-modifying therapy in type 1 diabetes. RECENT FINDINGS: We begin by describing the new understanding that islet autoimmunity, as identified by the presence of islet autoantibodies, inevitably leads to clinical type 1 diabetes. This understanding informs the new staging paradigm for type 1 diabetes, which suggests that type 1 diabetes may be recognized and diagnosed long before symptoms develop. Although it is known that nearly all individuals with established islet autoimmunity will eventually develop symptomatic type 1 diabetes (T1D), individual characteristics such as age and biomarker profile may predict rate of disease progression and response to treatment and may therefore be used to individualize therapy. Key research supports the use of immunotherapy in TID, although a paradigm shift is necessary before immunotherapy may transition from clinical trials to clinical practice. Recent and ongoing research as it relates to these concepts is described throughout.

Since the discovery of therapeutic insulin in 1922 and the development of the non-obese diabetic spontaneous mouse model in 1980, the establishment of Network for the Pancreatic Organ Donor with Diabetes (nPOD) in 2007 is arguably the most important milestone step in advancing type 1 diabetes (T1D) research. In this perspective, we briefly describe how nPOD is transforming T1D research via procuring and coordinating analysis of disease pathogenesis directly in human organs donated by deceased diabetic and control subjects. The successful precedent set up by nPOD is likely to spread far beyond the confines of research in T1D to revolutionize biomedical research of other disease using high quality procured human cells and tissues.
RESUMO
To address the functionality of diabetic adipose-derived stem cells in tissue engineering applications, adipose-derived stem cells isolated from patients with and without type II diabetes mellitus were cultured in bioreactor culture systems. The adipose-derived stem cells were differentiated into adipocytes and maintained as functional adipocytes. The bioreactor system utilizes a hollow fiber-based technology for three-dimensional perfusion of tissues in vitro, creating a model in which long-term culture of adipocytes is feasible, and providing a potential tool useful for drug discovery. Daily metabolic activity of the adipose-derived stem cells was analyzed within the medium recirculating throughout the bioreactor system. At experiment termination, tissues were extracted from bioreactors for immunohistological analyses in addition to gene and protein expression. Type II diabetic adipose-derived stem cells did not exhibit significantly different glucose consumption compared to adipose-derived stem cells from patients without type II diabetes (p > 0.05, N = 3). Expression of mature adipocyte genes was not significantly different between diabetic/non-diabetic groups (p > 0.05, N = 3). Protein expression of adipose tissue grown within all bioreactors was verified by Western blotting.The results from this small-scale study reveal adipose-derived stem cells from patients with type II diabetes when removed from diabetic environments behave metabolically similar to the same cells of non-diabetic patients when cultured in a three-dimensional perfusion bioreactor, suggesting that glucose transport across the adipocyte cell membrane, the hindrance of which being characteristic of type II diabetes, is dependent on environment. The presented observation describes a tissue-engineered tool for long-term cell culture and, following future adjustments to the culture environment and increased sample sizes, potentially for anti-diabetic drug testing.
RESUMO
Physicians working in biopharmaceutical companies are key components in the successful development of new diagnostic and therapeutic developments. They have a high level of responsibility for the safe performance of clinical studies and for evaluating the efficacy of new potential treatments in patients. Recently, articles in highly ranked scientific journals have challenged this work. This article highlights the shortcomings of those views. In contrast, we document that the majority of the physicians working in the pharmaceutical industry provide extremely high-quality work, in part forced by the rigorous regulatory framework this work has to comply with nowadays. We promote an open (and critical!) discussion while sharing industrial views and opinions with colleagues from academia. Only by a constructive cooperation between both worlds, avoiding a black-and-white view, will we achieve an instrumental and effective way in developing new and affordable diagnostic and therapeutic tools that are truly helpful and affordable for patients. If physicians in the industry take more pride in their work, this would be helpful in fostering such an approach.
