The presence of diabetes mellitus leads to a decrease in life quality in all domains. The aim of our study was to evaluate the quality of life (QOL) in diabetic patients and the factors affecting it in type 2 diabetic mellitus patients. We conducted a cross-sectional study that included 86 patients with type 2 diabetes mellitus, in the territory of the City of Niš. Health-related QOL of patients was measured using the short form survey (SF-36) that produces an 8-scale health profile. The average duration of diabetes was 12.76 ± 8.08 years. The best QOL in all areas was observed in patients diagnosed with diabetes less than 10 years ago p < 0.05) and younger than 65 years. Male respondents perceived a better QOL compared to women, especially in the vitality and pain domains. The patients with comorbidity (93.64%) had lower QOL score in all domains. There was no significant difference in the QOL of patients with diabetes compared to the level of education. High QOL represents an ultimate goal and an important outcome of all medical interventions in diabetic patients. Factors related to lower QOL included: older age, female gender, and existence of comorbidities. Uncontrolled diabetic patients had a lower QOL than controlled diabetics.

Antibiotics are the most frequently used drugs in hospitalized patients, but studies have shown that the prescribed antibiotics may be inappropriate and may contribute to antibiotic resistance. We carried out a survey of antibiotic consumption and antibiotic resistance in our tertiary care university hospital, from 2005 to 2013. We focus on cephalosporins, one of the most prescribed groups of antibiotics in the tertiary health care. The objective was to identify any relationship between ceftriaxone consumption and resistance by enterobacteria. Antibiotics consumption and antimicrobial resistance were monitored in the tertiary care university hospital from 2005 to 2013. Data on the use of antibiotics in surgical inpatients were obtained and expressed as defined daily doses per 100 bed days. Bacterial resistances were given as percentages of resistant isolates. There was an increasing trend in cephalosporins consumption from 9·56 DBD (2005) to 23·32 DBD (2013), with ceftriaxone as the most frequently used cephalosporin, 3·6 DBD (2005) to 10·78 DBD (2013). E. coli and P. mirabilis resistance to ceftriaxone increased significantly from 22% in 2005 to 47% in 2013 and from 31% in 2005 to 60% in 2013, respectively. We found a significant correlation between ceftriaxone consumption and E. coli resistance (r = 0·895, P < 0·05). Our study shows that cephalosporin consumption increased from 2005 to 2013, with ceftriaxone as the most prescribed antibiotic. E. coli and P. mirabilis resistance to ceftriaxone increased significantly over the study period. E. coli resistance increased with ceftriaxone consumption.

A considerable number of patients suffering from diabetes mellitus (DM) turn to self-medication using medicinal plants, preparations, and medicine. The aim of this study was to investigate self-medication using medicinal plants and the potential influence of health care professionals' advice or media information regarding the use of herbal dietary supplements with hypoglycemic effect in a population of patients with type 2 DM. This research, in the form of an analytic cross-sectional study, was conducted in 6 pharmacies in the territory of Nis, Serbia, during October 2013. The criterion set for the study was to include patients diagnosed with type 2 diabetes who used pharmacotherapy in addition to herbal supplements. Surveyed women showed a statistically significant difference in the frequency of using herbal supplements compared to men (P < 0.001). More frequent symptoms of hypoglycemia were reported in the group of diabetic respondents who used herbal dietary supplements (P < 0.05). The media was most responsible for influencing decisions about self-medication that included the use of herbal dietary supplements. The role of health professionals is indispensable and very important, especially when the media is a potential cause of seeking self-medication.

The aim of this study was to develop a population pharmacokinetic (PK) model for clearance of mycophenolic acid (MPA) in adult renal transplant recipients, to quantify the PK parameters and the influence of covariates on the MPA pharmacokinetic parameters. Parameters associated with plasma concentrations of MPA at steady-state were analyzed in 70 renal transplant recipients (mean age 42.97 years; mean total body weight 75.33 kg) using nonlinear mixed-effect modeling (NONMEM). Characteristics of patients screened for influence on the pharmacokinetic parameters were gender, age, body weight, time after transplantation, whether the patient was diagnosed as having diabetes mellitus, organ source (living or deceased donor), biochemical parameters and co-therapy (tacrolimus, cyclosporine, prednisolone, omeprazole, bisoprolol, carvedilol, nifedipine). A validation set of 25 renal transplant recipients was used to estimate the predictive performance of population pharmacokinetic model. Typical mean value of MPA oral clearance, estimated by base model (without covariates) was 0.741 L h(-1). During population modeling, the full model showed that clearance of the MPA was significantly influenced by age, total daily dose of MPA, creatinine clearance, albumin level, status and gender of a donor, and the nifedipine and tacrolimus co-therapy. In the final model, clearance of MPA was reported to be significantly influenced by age, total daily dose of MPA and thenifedipine co-therapy. The derived model describes adequately MPA clearance in terms of characteristics of our patients, offering basis for individual pharmacotherapy approach.
