Antibiotic treatment and antimicrobial resistance in children with urinary tract infections.

OBJECTIVES: The aim of this study was to describe antibiotic prescribing patterns and antimicrobial resistance rates in hospitalised children with febrile and afebrile urinary tract infections (UTIs). METHODS: Antibiotic prescriptions and antibiograms for neonates, infants and older children with UTI admitted to a general district hospital in Central Greece were evaluated. Data covering a 5-year period were collected retrospectively from the Paediatric Department's Electronic Clinical Archive. Patients were included based on clinical and microbiological criteria. Antimicrobial susceptibility was determined by the Kirby-Bauer disk diffusion method. RESULTS: A total of 230 patients were included in the study. Among 459 prescriptions identified, amikacin (31.2%) was the most common antibiotic prescribed in this population, followed by amoxicillin/clavulanic acid (17.4%) and ampicillin (13.5%). Children received prolonged intravenous (i.v.) treatments for febrile (mean ± S.D., 5.4 ± 1.45 days) and afebrile UTIs (mean ± S.D., 4.4 ± 1.64 days). A total of 236 pathogens were isolated. The main causative organism was Escherichia coli (79.2%) with high reported resistance rates to ampicillin (42.0%), trimethoprim/sulfamethoxazole (26.5%) and amoxicillin/clavulanic acid (12.2%); lower resistance rates were identified for third-generation cephalosporins (1.7%), nitrofurantoin (2.3%), ciprofloxacin (1.4%) and amikacin (0.9%). Klebsiella spp. isolates were highly resistant to cefaclor (27.3%). CONCLUSION: High prescribing rates for amikacin and penicillins (± ß-lactamase inhibitors) and prolonged i.v. treatments were observed. Escherichia coli was highly resistant to ampicillin, whilst third-generation cephalosporins exhibited greater in vitro efficacy. Establishment of antimicrobial stewardship programmes and regular monitoring of antimicrobial resistance could help to minimise inappropriate prescribing for UTIs.

Health-related quality of life of a very special population: monks of Holy Mountain Athos, Greece.

PURPOSE: The investigation of Health-Related Quality of Life (HRQOL) of Orthodox Christian monks who live at the Holy Mount Athos in Greece, and its correlation with demographic characteristics and Sense of Coherence (SOC-13). METHODS: A cross-sectional study was designed. The seven monasteries and five scetes with the largest number of monk population were invited to participate. Two monasteries and 1 scete gave their permission for the study. The final monks sample was formed by 166 monks from 215 who participated to the study. HRQOL was assessed using the SF-12 and Sense of Coherence the SOC-13 scales that were completed by monks from May to August 2012. Μultiple linear regression analyses were conducted to explore the association of the HRQOL subscales with the demographics and SOC-13. RESULTS: The mean age was 45.5 ± 13.0 years; 83.7% lived in communal monasteries, and the mean number of years in monasticism was 18.4 ± 12.1. The mean value of their Physical Component Summary (PCS) score was 47.3 ± 5.3, which is lower than in the general Greek men population, while their Mental Component Summary (MCS) score was 56.4 ± 5.8, which is higher than in the general Greek men population. The mean value of SOC-13 was 65.7 ± 6.5. Positive association for PCS appeared for place of living (ß = 5.43, SE = 1.27, p < 0.001) and negative association for age (ß = -0.16, SE = 0.03, p < 0.001) while for MCS for number of years in monasticism (ß = 0.07, SE = 0.06, p = 0.023) and sense of coherence (ß = 0.47, SE = 0.06, p < 0.001). CONCLUSIONS: The results indicated that monks had better mental health but worse physical health compared to the general Greek male population. More studies are required to validate the above findings.

Beliefs and practices of Greek doctors in relation to patients' adherence to antihypertensive medication.

Although it has been proven that decreasing the arterial blood pressure decreases cardiovascular morbidity and mortality, <25% of hypertensive patients receiving antihypertensive treatment achieve target values, which are mainly attributed to failure of the patients to comply to treatment. Ensuring patient compliance to antihypertensive treatment, to prevent the development of hypertension-associated complications, has proven to be challenging in several countries. The aim of the present study was to investigate the knowledge, perceptions and practices applied by doctors treating hypertensive patients regarding patient compliance to the prescribed treatment. We also aimed to assess the possible barriers physicians face to using reinforcement methods and currently available guidelines. A total of 202 doctors from the Serres and Drama prefectures of Greece participated in this study. The data collection comprised a quantitative method questionnaire and the data were processed using Stata 8.0 statistical software. The results demonstrated that 84.7% of the participating doctors do not use the current guidelines for compliance, whereas only 10.1% have consultations lasting >15 min when discussing the medication with their patients. In addition, the majority (84.7%) of the doctors do not practice peer mentoring and consider the most effective interventions to be providing information and discussing the medication with their patients. In conclusion, the level of patient compliance to antihypertensive medication is unsatisfactory and the main reason is considered to be the non-use of guidelines by the treating physicians. Patients may benefit from further education of health professionals in this field.

Group patient education: effectiveness of a brief intervention in people with type 2 diabetes mellitus in primary health care in Greece: a clinically controlled trial.

This study aims to assess the impact of a brief patient group education intervention in people with type 2 diabetes mellitus. The sample, 193 people with type 2 diabetes mellitus who were patients at the diabetic clinic of a primary health care setting in Attica, was assigned to two groups, intervention (138 individuals) and control group (55 individuals). The intervention group, instead of receiving standard care, attended a structured group educational programme using Conversation Maps while the control group had standard care. The main outcome measures were HbA1c, body mass index (BMI), triglycerides, high density lipoprotein (HDL), low density lipoprotein (LDL), measured at baseline and 6 months after the intervention. After 6 months, significant differences in changes of the studied parameters were observed between the groups in HbA1c, 1.4 (95% CI: 1.1, 1.7), (P < 0.001) and HDL -4.4 (95% CI: -8.1, -0.8), (P < 0.001) in favour of group education. Within the groups, the intervention group presented a significant reduction in HbA1c, -0.6 (95% CI: -0.8, -0.3), (P < 0.001), in BMI, -0.7 (95% CI: -0.9, -0.1), (P = 0.007), in triglycerides, -21.1 (95% CI: -47.1, -9.9), (P = 0.003) and LDL, -10.0 (95% CI: -22.5, -5.7), (P < 0.001), while in the control group significant reductions were observed in HbA1c, -0.5 (95% CI: -0.5, -0.3), (P = 0.003), in HLD, -4.1 (95% CI: -7.7, -2.3), (P = 0.001) and in LDL, -9.4 (95% CI: -19.9, -3.9), (P = 0.018). Group-based patient education using Conversation Maps for people with type 2 diabetes is more effective, compared with individual education, in diabetes self-management.

Expression of estrogen receptors in non-malignant mammary tissue modifies the association between insulin-like growth factor 1 and breast cancer risk.

BACKGROUND: Several studies have reported that the insulin-like growth factor 1 (IGF-1) is positively associated with estrogen receptor-positive [ER(+)] breast cancer risk, whereas there is little or no association with respect to ER(-) breast cancer. All comparisons of ER(+) breast cancer cases, however, have been made versus healthy controls, for whom there is no information about the ER expression in their mammary gland. PATIENTS AND METHODS: In the context of a case-control investigation conducted in Athens, Greece, we studied 102 women with incident ERα(+) breast cancer and compared their IGF-1 blood levels with those of 178 ERα(+) and 83 ERα(-) women with benign breast disease (BBD) who underwent biopsies in the context of their standard medical care. Data were analysed using multiple logistic regression and controlling for potential confounding variables. RESULTS: ERα(+) breast cancer patients had higher IGF-1 levels compared with women with BBD [odds ratio (OR) 1.36, 95% confidence interval (CI): 0.95-1.94, per 1 standard deviation (SD) increase in IGF-1 levels]. When ERα status of women with BBD was taken into account, the difference in IGF-1 levels between ERα(+) breast cancer patients and women with BBD was clearly driven by the comparison with BBD women who were ERα(+) (OR = 1.95, 95% CI: 1.31-2.89 per 1 SD increase in IGF-1 levels), whereas there was essentially no association with IGF-1 levels when ERα(+) breast cancer patients were compared with ERα(-) BBD women. These contrasts were particularly evident among post/peri-menopausal women. CONCLUSIONS: We found evidence in support of an interaction of IGF-1 with the expression of ERα in the non-malignant mammary tissue in the context of breast cancer pathogenesis. This is in line with previous evidence suggesting that IGF-1 increases the risk of ER(+) breast cancer.

A comparison of hormonal profiles between breast cancer and benign breast disease: a case-control study.

BACKGROUND: Benign breast disease (BBD), particularly proliferative BBD, is an established breast cancer risk factor. However, there has been no systematic attempt to compare the hormonal profiles of the two conditions. In a case-control investigation in Athens, Greece, we compared levels of estrogens, testosterone and insulin-like growth factor-1 (IGF-1), as well as their principal binding proteins, between breast cancer patients, women with BBD by histological type (proliferative and nonproliferative) and women with no breast pathology. PATIENTS AND METHODS: We studied 466 women with incident breast cancer, 704 women with BBD and 244 healthy women. We used multiple regression to compare log-transformed serum hormone levels of breast cancer patients with those of healthy women and women with BBD by histological type (proliferative and nonproliferative BBD). RESULTS: The hormonal profile of breast cancer in our study was in line with the generally accepted hormonal profile of this disease, as reported from large cohort studies. Compared with healthy women, breast cancer patients tended to have higher levels of steroid hormones. The evidence was strong for estrone (difference 21.5%, P < 0.001), weaker for testosterone (difference 15.8%, P = 0.07) and weaker still for estradiol (difference 12.0%, P = 0.18). Also compared with healthy women, breast cancer patients had barely higher levels of IGF-1 (difference 2.0%, P = 0.51), but had significantly lower levels of IGF binding protein 3 (IGFBP-3) (difference -6.7%, P = 0.001). Compared with women with BBD, breast cancer patients had nonstatistically significantly lower levels of steroid hormones, but they had higher levels of IGF-1 [difference 5.5%, 95% confidence interval (CI) 0.7% to 10.6%] and lower levels of IGFBP-3 (difference -3.7%, 95% CI -6.7% to -0.7%). Differences were more pronounced when breast cancer patients were contrasted to women with proliferative BBD. CONCLUSIONS: Our findings suggest that high levels of IGF-1 may be an important factor toward the evolution of BBD to breast cancer.

The hormonal profile of benign breast disease.

BACKGROUND: Limited information exists about the endocrine milieu of benign breast disease (BBD), a documented breast cancer risk factor. We compared blood levels of estrogens, testosterone and insulin-like growth factor-1 (IGF-1) between BBD patients by histological type and women without breast pathology. METHODS: We studied 578 BBD patients and 178 healthy women in Athens, Greece, who provided blood samples, and completed interviewer-administered questionnaires. RESULTS: Of the BBD patients, 254 had non-proliferative disease, 268 proliferative disease without atypia and 56 atypical hyperplasia. Comparing BBD patients with healthy women, the per cent differences (and 95% confidence intervals) for blood hormones, among pre-menopausal and peri/post-menopausal women, respectively, were: 22.4% (-4.0%, 56.1%) and 32.0% (5.6%, 65.1%) for estradiol; 26.2% (10.1%, 44.8%) and 30.9% (16.8%, 46.6%) for estrone; 19.5% (3.1%, 38.4%) and 16.5% (-5.0%, 42.9%) for testosterone; and -5.2% (-13.8%, 4.4%) and -12.1% (-19.8%, -3.6%) for IGF-1. Steroid hormones tended to be higher in proliferative compared with non-proliferative BBD. CONCLUSIONS: Circulating steroid hormones tend to be higher among women with BBD than women with no breast pathology and higher in proliferative than non-proliferative disease; these patterns are more evident among peri/post-menopausal women. In peri/post-menopausal women IGF-1 was lower among women with BBD compared with healthy women.

Sense of coherence in people with and without type 2 diabetes mellitus: an observational study from Greece.

Background Antonovsky's concept of sense of coherence (SOC) has been suggested to relate to health, especially mental health and preventive health behaviours. Psychological distress has been identified as a risk factor for pre-diabetes and type 2 diabetes mellitus. The study of SOC and diabetes has not received much attention in Greece. This study aims to explore the extent to which type 2 diabetes mellitus can affect the SOC score. Methods An observational design was used to test the study hypothesis that individuals with type 2 diabetes mellitus would have a lower SOC than those without diabetes mellitus. A total of 202 individuals were studied, consisting of 100 people with diabetes mellitus (the study group) and 102 people with non-chronic orthopaedic conditions (the control group). All of the participants were patients of the Diabetic Clinic or the Orthopaedic Clinic of Livadia Hospital in Central Greece. SOC was assessed using a 29-item SOC questionnaire that had been translated into Greek and validated. Results Patients without type 2 diabetes mellitus had 2.4 times higher odds of having a high SOC score than patients with type 2 diabetes mellitus (P = 0.036; odds ratio [OR] = 2.35, 95% confidence interval [CI] = 1.06-5.23). Male patients had 3.9 times higher odds of having a high SOC score (P < 0.001; OR = 3.85, 95% CI = 1.71-8.67) than female patients. With regard to education, patients with a lower level of education had almost three times higher odds of having a high SOC score than patients with a higher level of education (P = 0.024; OR = 2.97, 95% CI = 1.15-7.67). Conclusions This study adds to the existing literature and indicates that SOC is a health asset. A study with an experimental design would clarify the interesting hypothesis of this study.

Elevated soluble urokinase receptor values in CSF, age and bacterial meningitis infection are independent and additive risk factors of fatal outcome.

The aim of the present study was to evaluate the potential role of cerebrospinal fluid soluble urokinase receptor (suPAR) level, infection and age as risk factors for fatal outcome in patients suspected of having meningitis and/or bacteraemia on admission to hospital. A total of 545 cerebrospinal fluid samples from patients with clinically suspected meningitis were sent to the Hellenic National Meningitis Reference Laboratory. Ten of 545 (1.83%) patients died. Analysis by receiver operating characteristics (ROC) curve revealed that both suPAR and age were significant for prediction of fatal outcome. Patients with levels of suPAR above the cut-off values and age ≥ 51 years, or patients in which either Neisseria meningitis or Streptococcus pneumoniae were detected were categorized as high risk patients. The combination of the above three predictors (suPAR, age and infectious agent) in a logistic regression model with outcome of infection as the dependent variable yielded an overall odds ratio (OR = 85.7, 95% CI 10.6-690.2) with both sensitivity and specificity being equal to the value of 0.9. In conclusion, suPAR, age and type of infection have an additive effect in predicting mortality among patients suspected of meningitis.
