There is considerable evidence suggesting that cytokines play important roles in pain and in mediating neurovascular inflammation associated with migraine headaches. Although consensus exists to recommend topiramate (TPM) for migraine prevention, the mechanism of action in this regard is unknown. We measured serum interleukin-6 (IL-6) levels in 66 migraine patients. Of these patients, 23 (34.9%) were taking TPM for migraine, and 43 (65.1%) were not. The IL-6 levels were compared with those of healthy controls without migraine, from the population living in the same region. The mean IL-6 levels in migraine patients taking TPM and patients who did not were 67.06 +/- 92.09 pg/mL and 44.09 +/- 59.19 pg/mL, respectively (P > 0.05). The IL-6 levels were higher in the patients taking TPM. The IL-6 level in the controls was 8.60 +/- 7.36 pg/mL, which was significantly lower than the patient group using TPM (P = 0.001). Our results show that, although IL-6 may be involved in pain induction or inflammatory mechanisms of migraine attacks, the serum IL-6 level was not reduced in migraine patients receiving TPM therapy. In conclusion, we found high IL-6 levels in migraine patients both with and without TPM therapy, suggesting that high IL-6 levels during pain-free periods could be a conditioning factor, making patients more vulnerable to pain attacks in chronic migraine. Further studies investigating the possible mechanism of TPM in migraine are needed.
In this study, the activity and diversity of nitrogen converters, ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB), ammonia-oxidizing archaea (AOA) and Anammox bacteria in a pilot-scale membrane bioreactor (MBR) were investigated and monitored using amoA and 16S rDNA-based molecular tools. The pilot-scale MBR (100 m(3)/day) was located inside the full-scale Pasakoy Advanced Wastewater Treatment Plant (WWTP), and operated for approximately 5 months without sludge purge. During 148 days of operation, volatile suspended solids (VSS) concentration increased from 2,454 mg/L to 10,855 mg/L and the average organic carbon and ammonia nitrogen removal rates were 92% and 99%, respectively. Real-time PCR results indicated that the fraction of AOB increased from 2.94% to 4.05% when VSS concentration reached to 3,750 mg/L throughout 148 days of operation. At higher VSS concentrations, the fraction of AOB declined gradually to 1.15% while the fraction of Nitrospira population was varied between 8.23 and 13.01%. However, significant change or any positive and negative correlations between VSS concentration and Nitrospira population were not observed in this period. The phylogenetic analysis revealed that MBR harbored diverse AOB community which was related to the Nitrosomonas and Nitrosospira lineage. Candidatus Nitrospira defluvii was the only detected NOB in this study.
This study suggests that compatible ureteroscope-ureteral access sheath combinations with a lumen difference of more than 1.5 Fr can provide safe outcomes in terms of renal blood flow. F-URS can safely be performed in terms of renal perfusion and complication rates with appropriate equipment and instruments.
Introduction:The human population is aging at an astonishing rate. The aim of this study is to capture a situation snapshot revealing the proportion of individuals aged 65 years and over among inpatients in healthcare institutions in Turkey and the prevalence and type of infections in this patient group in order to draw a road map. Materials and Methods: Hospitalized patients over 65 years at any of the 62 hospitals in 29 cities across Turkey on February 9, 2017 were included in the study. Web-based SurveyMonkey was used for data recording and evaluation system. Results: Of 17,351 patients 5871 (33.8%) were !65 years old. The mean age was 75.1 AE7.2 years; 3075 (52.4%) patients were male. Infection was reason for admission for 1556 (26.5%) patients. Pneumonia was the most common infection. The median length of hospital stay was 5 days (IQR: 2-11 days). The Antibiotic therapy was initiated for 2917 (49.7%) patients at the time of admission, and 23% of the antibiotics prescribed were inappropriate. Healthcare-associated infections developed in 1059 (18%) patients. Urinary catheters were placed in 2388 (40.7%) patients with 7.5% invalid indication.
Conclusion:This study used real data to reveal the proportion of elderly patients in hospital admissions. The interventions done, infections developed during hospitalization, length of hospital stay, and excessive drug load emphasize the significant impact on health costs and illustrate the importance of preventive medicine in this group of patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
