Electrodermal activity and heart rate variability for detection of peripheral abnormalities in type 2 diabetes: A review

Modern medicine exhibits an upward trend towards non-invasive methods for early detection of disease and long-term monitoring of patients' health. Diabetes mellitus and its complications are a promising area for implementation of new medical diagnostic devices. One of the most serious complications of diabetes is diabetic foot ulcer. The main causes responsible for diabetic foot ulcer are ischemia caused by peripheral artery disease and diabetic neuropathy caused by polyol pathway-induced oxidative stress. Autonomic neuropathy impairs function of sweat glands, which can be measured by electrodermal activity. On the other hand, autonomic neuropathy leads to changes in heart rate variability, which is used to assess autonomic regulation of the sinoatrial node. Both methods are enough sensitive to detect pathological changes caused by autonomic neuropathy and are promising screening methods for early diagnosis of diabetic neuropathy, which could prevent the onset of diabetic ulcer.

Evaluation of Efficacy of Bromocriptine as a Therapeutic Modality in the Treatment of Diabetes Mellitus: A Systematic Review

Diabetes mellitus (DM), one of the oldest diseases known to mankind has always been difficult to treat even with the availability of a variety of medications. In such a scenario, the Food and Drug Administration (FDA) has approved a novel therapeutic, bromocriptine, with a different mechanism of action than the traditional medications since 2009 but has not been used as either first-line therapy or add-on therapy. In this systematic review, we searched databases like PubMed, Medline, PubMed Central, Cochrane Library, Clinicaltrials.gov, and Wiley Online Library. The selected articles were screened using inclusion and exclusion criteria and quality appraised; finally, 11 studies including eight clinical trials and three narrative reviews were included. It was found that an increase in dopamine and serotonin levels were hypothesized to convert the insulin-resistant (IR) state to an insulin-sensitive (IS) state. Hence in DM, as there is an IR state, the administration of dopamine was hypothesized to increase insulin sensitivity. In our study based on included studies, it was found that bromocriptine was superior as an add-on therapy to metformin compared to metformin alone, also it was found beneficial in people failing treatment with any one oral hypoglycemic agent. On the contrary, bromocriptine was found inferior to teneligliptin in treating DM. Still, more studies are required to make an accurate and reliable assessment of the efficacy of bromocriptine in treating DM.

DVT as the Initial Presentation of Multiple Myeloma: A Rare Case Report and Literature Review

Multiple myeloma patients are recognized to have a higher risk of venous thrombosis. The cause of this could be attributed to several risk factors, such as circulating prothrombotic microparticles, disease-specific variables, and alterations in coagulation and fibrinolysis factors. Recent research has revealed that these individuals also experience greater arterial thrombosis, including acute myocardial infarction and stroke. In this case report, we present the clinical profile and management of a 42-year-old patient who presented with signs and symptoms of deep venous thrombosis (DVT) and was diagnosed with multiple myeloma. The aim of this case report is to highlight a rare clinical presentation and diagnostic workup in a patient with multiple myeloma. Additionally, we discuss the possible factors provoking the development of DVT as a first presentation before treatment initiation and their possible mechanisms.

The Associations of Auto-Brewery Syndrome and Diabetes Mellitus: A Literature Review and Clinical Perspective

Endogenous production of alcohol without the external intake of alcohol is called auto-brewery syndrome (ABS), and to get its levels to rise to a level that it has physical symptoms of alcohol intake is rare. The most common cause of ABS is the metabolism of ingested carbohydrates by intestinal microflora. This occurrence does not happen in all normal individuals but only in some high-risk individuals. Patients with diabetes mellitus (DM) have been hypothesized to be at high risk for ABS. We searched databases, such as PubMed, Medline, and PubMed Central, to search for existing literature with relevant keywords. In the finalized review, we have included 30 relevant articles. Alcohol formed in the gut gets absorbed in the bloodstream and immediately gets metabolized, so usually it does not achieve a level in blood high enough to cause symptoms. In high-risk patients, there is an increase in the level of bloodstream alcohol above a certain level, so it shows symptoms. Because there is higher blood glucose in DM, the patients have been shown to be at increased risk for developing ABS. Similarly, obesity is also a risk factor for DM, making it a high-risk condition for ABS. The most involved pathogens are Candida and Saccharomyces.

Clinical Spectrum and Medical Comorbidities in Tuberculosis: A Hospital-Based Study in Northeast India

Background

Tuberculosis (TB) is one of the most common infectious diseases and is commonly associated with comorbidities. However, data regarding TB and comorbidities are lacking from northeast India. The aim of the study is to see the clinical spectrum of TB and the frequency of comorbidities.

Methods

This was a prospective observational study of all hospitalized TB patients between January 2016 and June 2017 who were selected by consecutive sampling. Data were analyzed using SPSS v. 17.0 (IBM Corp., Armonk, NY), and a p-value of <0.05 was considered significant.

Results

Of the 173 patients selected, the mean age was 41.05±17.04 years with a male:female ratio of 4.27:1. Pulmonary TB (PTB) was found in 43.94%, extra-pulmonary TB (EPTB) in 52.02%, and disseminated TB in 4.04%. Fever (61.27%) was the most common presentation, followed by cough (54.33%) and breathlessness (32.94%). Of the 76 patients with PTB and seven with disseminated TB, making a total of 83 patients, 56 (67.4%) were sputum positive. Out of 90 patients suffering from EPTB, pleural effusion (53.33%) was the commonest type of EPTB, followed by central nervous system (CNS) tuberculosis (26.66%) and abdominal tuberculosis (8.88%). Comorbidities were present in 53.17% of the patients, of which diabetes mellitus (DM) (26.58%) and hypertension (17.34%) were the most common. Comorbid conditions were significantly higher in PTB than EPTB (51 of 83 vs. 41 of 90, p<0.05). Mean glycated hemoglobin (HbA1c) was significantly higher in PTB as compared to EPTB (8.74±2.04 vs. 7.58±0.29, p<0.05).

Conclusion

Comorbidities, particularly DM, were present in half of the patients, mostly in PTB than EPTB, with glycemic control being significantly poorer in PTB patients.

AB157. Treatment of diabetic erectile dysfunction by using endothelial progenitor cells genetically modified by human telomerase reverse transcriptase

Objective

Erectile dysfunction (ED) is one of the most common complications of diabetes mellitus (DM). Under the background that effectivity of treatments for diabetic ED are quite poor, stem cell therapy is emerging a useful method. The aim of this study is to evaluate the possibility and mechanism of treatment of diabetic ED with endothelial progenitor cells (EPCs) genetically modified by human telomerase reverse transcriptase (hTERT).

Methods

Rat EPCs were isolated and transfected with hTERT (EPCs-hTERT). The paracrine characters and resistance to oxidative stress of EPCs-hTERT was determined in vitro. Thirty SD male rats were divided into five groups: diabetic ED rats, diabetic ED rats treated with EPCs, diabetic ED rats treated with EPCs-control, diabetic ED rats treated with EPCs-hTERT, normal control rats. Diabetes was induced by intraperitoneal injection of streptozotocin. After 8 weeks, diabetic ED rats were selected by apomorphine (APO) test. After injection of EPCs for 2 weeks, intracavernosal pressure (ICP) was measured by means of electrical stimulation for each group. Concentration of growth factors, the amount of EPCs and endothelium/smooth muscle content were evaluated in vivo.

Results

EPCs-hTERT showed stable expression of hTERT at the level of, mRNA and protein for more than 40 passages. EPCs-hTERT could paracrine more VEGF, HGF and bFGF. EPCs’ ability of resistance to oxidative stress was dramatically improved by tranfection of hTERT. ICP/mean arterial pressure (MAP) ratio induced by electrical stimulation in diabetic ED treated with EPCs-hTERT was markably higher than diabetic ED rats treated with EPCs or EPCs-control. Immunofluorescence demonstrated that more cells survived in penile tissues after implantation of EPC-hTERT. More growth factors were detected, and the endothelium/smooth muscle content was increase in penile tissues.

Conclusions

The paracrine effect and resistance to oxidative stress of EPCs-hTERT contributed to the improvement of erection of diabetic ED rats.

Diabetes mellitus may induce cardiovascular disease by decreasing neuroplasticity

Neuroplasticity has been defined "the ability of the nervous system to respond to intrinsic or extrinsic stimuli by reorganizing its structure, function and connections". The nervous system monitors and coordinates internal organ function. Thus neuroplasticity may be associated with the pathogenesis of other diseases besides neuropsychiatric diseases. Decreased neuroplasticity is associated with cardiovascular disease (CVD) and a disease related to decreased neuroplasticity may confer a greater CVD risk. Diabetes mellitus (DM) is related to CVD and DM induces decreased neuroplasticity, which is manifested as depression, Alzheimer's disease and diabetic neuropathy. Therefore we conclude that DM may induce CVD by decreasing neuroplasticity.
