THE PREVALENCE OF POLYNEUROPATHY IN THE PRE-DIABETES PERIOD.

Objective: This study aims to determine the prevalence of neuropathy in the prediabetic period. Design Subjects and Method: Informed consent was attained from the patients who volunteered to participate in the study after ethics committee approval was obtained. Patients under the age of 18, having vitamin B12 or folic acid deficiency, history of collagen tissue-rheumatological disease, chronic kidney failure, cirrhosis, ethylism, thyroid disease, autoimmune disease, malignancy, tuberculosis, type 1 or 2 diabetes mellitus and pregnant women were excluded from the study. Patients diagnosed with prediabetes were evaluated by the DN4 neuropathy complaint questionnaire. Neuropathy was diagnosed in patients having a score of four or more. For the statistical analyses Student t-test, Pearson chi-square test, and Fisher's exact test were performed using the NCSS program. Results: A total of 224 volunteers, 167 women and 57 men, were included in the study. The mean age of the participants was 51 and the mean level of hemoglobin A1C was 5.9. Neuropathy was detected in 45% of the cases. Especially in women, there was a significant increase in the frequency of neuropathy compared to men. The most common complaints found in our study were burning sensation and numbness in the extremities. Conclusions: Similar to diabetic patients, prediabetic patients also have a high rate of neuropathy. For the early diagnosis of neuropathy and to be treated promptly, screening tests such as DN4 should be performed for all prediabetic patients. According to the test results, advanced examinations such as EMG or biopsy should be performed earlier.

The effects of high intensity-interval training on vaspin, adiponectin and leptin levels in women with polycystic ovary syndrome.

AIM: We aimed to investigate the metabolic effects of HIIT exercise on PCOS patients and how it affects adiponectin, vaspin and leptin. MATERIAL AND METHODS: Twenty women with PCOS were included in the study and were divided into two groups. HIIT program was applied for 10 PCOS and Medium Intensity Continuous Training (MICT) program was applied for other 10 PCOS. At the beginning and at the end of the study, total cholesterol, low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), triglyceride(TG), insulin, Adiponectin, Leptin, Vaspin levels of both PCOS groups were evaluated. RESULTS: When PCOS patients by performed HIIT exercise for 12 weeks, we found that the levels of leptin and vaspin did not change while adiponectin levels increased. Moreover serum levels of insulin, TG, total cholesterol, LDL-C decreased but levels of HDL-C increased. CONCLUSION: HIIT increased in the adiponectin levels in women with PCOS and provided more weight loss.

The protective effect of vitamin D against carbon tetrachloride damage to the rat liver.

We investigated the protective effect of vitamin D against liver damage caused by carbon tetrachloride (CCl4). Twenty-four male rats were divided into four equal groups: G1, untreated controls; G2, administered CCl4; G3, administered both CCl4 and vitamin D for 10 weeks; G4, administered CCl4 for 10 weeks and vitamin D for 12 weeks. At the end of experiment, intracardiac blood samples were taken and liver samples were removed. Hepatic damage due to CCl4 was assessed using biochemistry and histopathology. Glutathione (GSH) levels decreased, while malondialdehyde (MDA) levels increased in liver tissues of G2. Alanine transaminase (ALT), alkaline phosphatase (ALP), and gamma-glutamyl-transaminase (GGT) levels increased, while albumin (ALB) levels decreased. Hepatocyte degeneration, lobular disorder, sinusoid dilation, focal necrotic areas, hyperemia, and glycogen loss were observed. Hepatic fibrosis was observed around portal areas and central veins. Bridging fibrous septa were formed between portal veins. By immunohistochemistry, both matrix metalloproteinase-9 (MMP-9) and desmin reactivity were increased. All aspects of liver damage were at least partially prevented in rats treated with vitamin D. Vitamin D appears to act as an antioxidant and anti-fibrotic to protect the rat liver against damage.

Histoprotective effect of vitamin D against carbon tetrachloride nephrotoxicity in rats.

This study investigated the protective effect of vitamin D against carbon tetrachloride (CCl4)-induced nephrotoxicity in rats. Adult male Wistar albino rats were divided into four groups ((A) control; (B) 10-week exposure to CCl4; (C) 10-week exposure to CCl4 + vitamin D treatment; and (D) 10-week exposure to CCl4 + 12 weeks of vitamin D treatment). The CCl4 dose (1.5 ml kg(-1)) was injected subcutaneously twice a week, while the 0.5 mg kg(-1) dose of vitamin D was administered intraperitoneally every day, as appropriate for each group. Whole animal and kidney weights as well as serum urea, creatinine, and glucose levels were measured. Kidney tissue sections were stained with hematoxylin-eosin, Masson's trichrome, and periodic acid-Schiff. Tubular and glomerular degeneration were detected in the kidney tissues of CCl4-treated rats, together with dilatation and vacuolization within the tubules and hemorrhage in the intertubular region. In the kidney glomeruli; congestion, atrophy, and adhesion to parietal layer were observed. Tissue disorganization and aggregation of Bowman's capsules were noted. Mononuclear cell infiltration was observed between the glomeruli and the tubules. In contrast, the kidney sections and functional parameters of vitamin D-treated rats were similar to the controls, suggesting that vitamin D treatment is able to reduce renal damage.

A long-term study examining the antibacterial effectiveness of Agion silver zeolite technology on door handles within a college campus.

Laboratory studies have shown that small concentrations of silver are effective at inhibiting the growth micro-organisms through the disruption of important cell structures and processes. The additional ability to incorporate silver into surfaces has increased the usage of silver in the medical field and expanded its use into the consumer market. To understand the impact of increased silver-containing antimicrobial use, it is important to determine whether silver-based consumer goods are effective at reducing bacterial populations. Our study examined the antibacterial effectiveness of Agion silver zeolite technology applied to 25 silver- and control-coated door handles across a college campus. Door handles were sampled for 6 week periods in both the fall and spring semester, and bacteria were cultured and enumerated on tryptic soy agar (TSA), MacConkey agar (MAC) and mannitol salt agar (MSA). A significant difference was observed between the bacterial populations isolated from silver- and control-coated door handles after 3 years. However, bacteria were consistently isolated from silver-coated door handles suggesting that the silver zeolite was only effective against a portion of the bacterial populations, and further studies are necessary to determine the identities of the isolated bacteria and the prevalence of silver resistance.
