Shift work, quality of life and work ability among Croatian hospital nurses.
This paper is a report of a study of the associations of shift work with work ability and quality of life (QoL) among clinical nurses. A cross-sectional study was conducted in 2007-2008 on 1124 nurses using the Work Ability Index Questionnaire and the Quality of Life Questionnaire (WHOQOL-BREF). Lower education was a predictor for low level of work ability and low physical health domain of QoL. ⋯ Shift workers had higher level of level of work ability, but clinically insignificant. The study provides no evidence of a significant association between shift work and work ability or quality of life. Education has a positive association with nurses' work ability and quality of life.

Pain typically accompanies acute herpes zoster and persists well beyond rash healing. Different types of pain are reported by patients with herpes zoster. Current studies show that these types of pain vary with respect to their presence, location, duration, intensity and quality, hence pain needs to be analyzed more thoroughly. ⋯ The results have shown that the patients report about spontaneous pain mostly in terms of the following qualities of high level pain intensity: throbbing, aching, hot-burning and sharp. The results also demonstrate that herpes zoster pain significantly affects the patients' everyday living quality and their emotional health. Comprehensive assessment of pain is necessary for clinical research about the epidemiology, natural history, pathophysiologic mechanisms, treatment, and prevention of pain in herpes zoster.

Analysis of purity profiles of generic lisinopril tablets marketed in Croatia.
In view of an increasing number of generic drugs emerging, a comparative study was performed including the approved lisinopril preparations in the form of tablets marketed in Croatia, to compare purity profiles of generic drugs versus the original medicinal product. Several batches of each individual medicinal product at different stages of their shelf life were analyzed. Impurities were determined by means of high performance liquid chromatography (HPLC). ⋯ Original drug, as compared to its generic copies, had the lowest values and also the lowest variability of all the tested parameters--type, total number and content of impurities--suggesting that its manufacturing process is to certain degree better controlled compared to other manufacturers. A characteristic impurity C appearing in all the assessed preparations has the lowest levels in the original drug, whereas the amount of the highest unknown impurity does not exceed 0.10% in any of the analyzed preparations. Although the original drug stands out from all the generic preparations with its purity, it can be generally concluded that, as regarding impurities levels, all the analyzed medicinal products are within the ranges of specification limits; accordingly, it is therefore not expected that, in case of lisinopril tablets, administration of the original drug as compared to any of its generic drugs, will be safer for the patient.

Clinical TrialThermography--a feasible method for screening breast cancer?
Potential use of thermography for more effective detection of breast carcinoma was evaluated on 26 patients scheduled for breast carcinoma surgery. Ultrasonographic scan, mammography and thermography were performed at the University Hospital for Tumors. Thermographic imaging was performed using a new generation of digital thermal cameras with high sensitivity and resolution (ThermoTracer TH7102WL, NEC). ⋯ The pathohistological method (PHD) recorded 75.75% malignant changes within the total number of samples. Statistical analysis of the data has shown a probability of a correct mammographic finding in 85% of the cases (sensitivity of 85%, specificity of 84%) and a probability of a correct thermographic finding in 92% of the cases (sensitivity of 100%, specificity of 79%). As breast cancer remains the most prevalent cancer in women and thermography exhibited superior sensitivity, we believe that thermography should immediately find its place in the screening programs for early detection of breast carcinoma, in order to reduce the sufferings from this devastating disease.

P2RY12 gene polymorphisms and effect of clopidogrel on platelet aggregation.
Objective of this study was to assess platelet response to clopidogrel and its association with certain single nucleotide polymorphisms (SNPs) of the P2RY12 gene. Several studies have shown that patients with poor in vitro response to clopidogrel have worse outcomes after coronary interventions. Pharmacological response to clopidogrel is mediated by the P2Y12 platelet receptor, therefore, SNPs of the P2RY12 gene may account for some of the observed variability in the cardiovascular risk. ⋯ There was no relation between poor response to clopidogrel and any other genetic variant. Our results suggest that 18C > T SNP of the P2RY12 gene may be an independent predictor of pharmacological response to clopidogrel. Larger prospective studies are needed to confirm this link and assess its possible clinical consequences.
