Co-administration of viscous fiber, Salba-chia and ginseng on glycemic management in type 2 diabetes: a double-blind randomized controlled trial.

PURPOSE: Viscous dietary fiber, functional seeds and ginseng roots have individually been proposed for the management of diabetes. We explored whether their co-administration would improve glycemic control in type 2 diabetes beyond conventional therapy. METHODS: In a randomized, double-blind, controlled trial conducted at two academic centers (Toronto, Canada and Zagreb, Croatia), individuals with type 2 diabetes were assigned to either an active intervention (10 g viscous fiber, 60 g white chia seeds, 1.5 g American and 0.75 g Korean red ginseng extracts), or energy and fiber-matched control (53 g oat bran, 25 g inulin, 25 g maltodextrose and 2.25 g wheat bran) intervention for 24 weeks, while on conventional standard of care. The prespecified primary endpoint was end difference at week 24 in HbA1c, following an intent-to-treat analysis adjusted for center and baseline. RESULTS: Between January 2016 and April 2018, 104 participants (60M:44F; mean ± SEM age 59 ± 0.8 years; BMI 29.0 ± 0.4 kg/m2; HbA1c 7.0 ± 0.6%) managed with antihyperglycemic agent(s) (n = 98) or lifestyle (n = 6), were randomized (n = 52 test; n = 52 control). At week 24, HbA1c levels were 0.27 ± 0.1% lower on test compared to control (p = 0.03). There was a tendency towards an interaction by baseline HbA1c (p = 0.07), in which a greater reduction was seen in participants with baseline HbA1c > 7% vs ≤ 7% (- 0.56 ± 0.2% vs 0.03 ± 0.2%). Diet and body weight remained unchanged. The interventions were well tolerated with no related adverse events and with high retention rate of 84%. CONCLUSIONS: Co-administration of selected dietary and herbal therapies was well-tolerated and may provide greater glycemic control as add-on therapy in type 2 diabetes. Registration: Clinicaltrials.gov NCT02553382 (registered on September 17, 2015).

Modified cotton socks--possibility to protect from diabetic foot infection.

Diabetes has become a major public health problem and grows rapidly in the most developed countries of the world. Beside genetic and environmental factors, lifestyle habits play an important role in the development and progression of diabetes mellitus. According to the World Health Organization (WHO) about 15% of diabetic patients develop a foot ulcer in need of medical care. Infection is a serious complication and it is the major responsible cause of lower limb amputation. In this paper the possibility to protect from diabetic foot infection with modified cotton socks. Therefore, the socks made of modified cotton yarn by natural minerals and active carbon were investigated in vitro (fabric hand-friction and adsorption) and in vivo (3 IDDM, 4NIDDM, 3 GDM to sweat and fabric hand) to accomplish highest possible level of comfort for diabetic patients. Antimicrobial protection to Gram positive, Gram negative and micro fungi was determined as well. For durability all the characteristics were investigated after 15 washing cycles.

Vein diameter after intraoperative dilatation with vessel probes as a predictor of success of hemodialysis arteriovenous fistulas.

BACKGROUND: Vascular access is "the life line" for patients on chronic hemodialysis. The autogenous arteriovenous fistula provides the best access to the circulation because of low complication rate, long-term use, and lower cost, compared to arteriovenous graft and central venous catheter. The primary objective of this prospective study was to investigate the predictive value of vein diameter after intraoperative dilatation with vessel probes on hemodialysis fistula maturation. MATERIAL AND METHODS: Ninety-three fistulas were performed by a single surgeon from February 1, 2006 to January 31, 2009. Intraoperative vein dilatation with vessel probes was attempted in all fistulas. Measurements of the feeding artery diameter, vein diameter and the increased vein diameter after intraoperative dilatation were performed and immediate failure, early patency, early failure, primary patency, and fistula survival outcomes were recorded during 48-month follow-up. RESULTS: Early failure occurred in 20% of fistulas and 70% matured sufficiently for cannulation. Variables with significant impact on the failure to mature by univariate analysis were: body-mass index (P=0.041), artery diameter (P<0.001), vein diameter (P=0.004), and vein diameter after dilatation (P=0.002). However, but multivariate analysis showed that only body-mass index (P=0.038), artery diameter (P=0.001), and the diameter of the vein after dilatation (P=0.018) significantly affected maturation. In a group of 56 (60%) patients with vein diameter before dilatation ≤ 2 mm, among vessel characteristics found by multivariate analysis, only vein diameter after dilatation (P=0.004) significantly affected function. CONCLUSIONS: Artery diameter and vein diameter after intraoperative dilatation with vessel probes were the main predictors of fistula function.

Lifestyle habits of Croatian diabetic population: observations from the Croatian Adult Health Survey.

The aim of this study was to assess the behavioural risk factors in Croatian diabetic population and to compare them with the lifestyle habits of individuals with no known history of diabetes. The study was a part of the Croatian Adult Health Survey (CAHS), a cross-sectional survey that provided comprehensive health assessment of the Croatian adult population. Risk factors were defined as an unhealthy nutritional regimen, excessive alcohol consumption, smoking and lack of physical activity. Physical inactivity was the most prevalent risk factor observed in a significant number of both diabetic and non-diabetic subjects (44.8% and 29.1%). It was also the only behavioural risk factor that was more prevalent in the diabetic individuals as compared to those without diabetes. Alcohol consumption did not vary significantly between the two groups (5.8% vs. 6.3%), while unhealthy dietary pattern and smoking were less frequent in respondents with diabetes (10.0% vs. 16.5% and 14.3% vs. 23.2%, respectively). Among diabetic patients, a significantly larger proportion of men than women reported smoking (19.2% vs. 10.0%), whereas no such sex-related differences were observed in other behavioural risk factors. Although the most prominent risk factor in diabetic patients was physical inactivity, a significant proportion of respondents with diabetes also reported the presence of other risk factors investigated in this survey. Since the majority of diabetic patients do not reach their treatment goals, there is a substantial need for curative and preventive interventions. Given the importance of physical activity in the treatment and prevention of diabetes and the high proportion of inactive diabetic patients, any future preventive programme in Croatia should address that risk as well.

The importance of success prediction in angioaccess surgery.

Access to the circulation is an "Achilles' heel" of chronic hemodialysis. According to the current guidelines, autologous arteriovenous fistula is the best choice available. However, the impossibility of immediate use and the high rate of non-matured fistulas place fistula far from an ideal hemodialysis vascular access. The first attempt at constructing an angioaccess should result in functional access as much as possible. After failed attempts, patients and nephrologists lose their patience and confidence, which results in high percentage of central venous catheter use. Predictive models could help, but clinical judgment still remains crucial. Early referral to the nephrologist and vascular access surgeon, careful preoperative examinations, preparation of patients and duplex sonography mapping of the vessels are very important in the preoperative stage. In the operative stage, it is crucial to understand that angioaccess procedures should not be considered as minor procedures and these operations must be performed by surgeons with demonstrable interest and experience. In the postoperative stage, appropriate surveillance of the maturation process is also important, as well as good cannulation skills of the dialysis staff. The purpose of this review article is to stress the importance of success prediction in order to avoid unsuccessful attempts in angioaccess surgery.

The novella about diabetic nephropathy.

Diabetic nephropathy is a common complication in patients with diabetes mellitus and one of the major reasons for renal replacement therapy in Croatia, Europe and the United States. It is characterized by proteinuria, decline in glomerular filtration, hypertension, and high risk of cardiovascular morbidity and mortality. Deterioration of renal function in diabetic nephropathy develops through five clinical stages characterized by the respective histologic description. Genetic susceptibility, hyperglycemia, high blood pressure and duration of diabetes mellitus definitely play a role in the pathogenetic sequence. Early diagnosis, appropriate patient follow up and treatment are essential to improve the outcomes. Interdisciplinary approach and close collaboration of nephrologists and diabetologists are essential for timely detection of disease progression. Tight glycemic control under the supervision of diabetologists, screening of patients, and once a year report of albuminuria and glomerular filtration allow for detection of renal damage in the early stages and timely referral to a nephrologist. The points of interest given in this overview are description of clinical staging in relation to pathologic classification, repetition of basic causal features, and brief analysis of treatment.
