The prevalence of probable migraine and sleep quality among women aged 20-49 living in a semi-rural area in western Turkey

Background: We aimed to evaluate the prevalence of probable migraine, to examine the factors associated with probable migraine and to assess the level of sleep quality among women aged 20-45 who were living in the county town named Mahmudiye, in Eskisehir, in Turkey.Methods: The study was carried out in all women aged 20-45 years in Mahmudiye. 69.2% of women (n=570) comprised the study group. Questionnaire consisted of three parts: The first part included several socio-demographic, nutritional and health characteristics. The second part included questions about the headache type and third part included Pittsburgh Sleep Quality Index (PSQI). Migraine type headache was scanned via the International Headache Society (IHS) criteria for migraine. There were eight criteria which were defined by IHS. Individuals who possessed the six of the eight criteria were defined as “probable migraine”.Results: The mean age of the participants was 32.8±7.3 years. Prevalence of probable migraine was 13.3% (n=60) and it was significantly higher in women who have been smoking and who had a physician diagnosed chronic diseases. Of the women, 45.1% had poor sleep quality based on the PSQI. The sleep quality of probable migraineurs was found significantly lower than healthy women.Conclusions: To control the probable migraine symptoms and attacks, we suggest to giving regular treatment to women with chronic diseases and reducing the smoking.

New description of vagal nerve commanted intrapancreatic taste buds and blood glucose level: An experimental analysis

Introduction: There have been thousands of neurochemical mechanism about blood glucose level regulation, but intrapancreatic taste buds and their roles in blood glucose level has not been described. We aimed to investigate if there are taste buds cored neural networks in the pancreas, and there is any relationship between blood glucose levels. Methods: This examination was done on 32 chosen rats with their glucose levels. Animals are divided into owned blood glucose levels. If mean glucose levels were equal to 105 ± 10 mg/dL accepted as euglycemic (G-I; n = 14), 142 ± 18 mg/dL values accepted as hyperglycemic (G-II; n = 9) and 89 ± 9 mg/dL accepted as hypoglycemic (G-III; n = 9). After the experiment, animals were sacrificed under general anesthesia. Their pancreatic tissues were examined histological methods and numbers of newly described taste bud networks analyzed by Stereological methods. Results compared with Mann-Whitney U test P < 0.005 considered as significant. Results: The mean normal blood glucose level (mg/dL) and taste bud network densities of per cm3 were: 105 ± 10 mg/dL; 156±21 in G-I; 142 ± 18 mg/dL and 95 ± 14 in G-II and 89 ± 9 mg/dL and 232 ± 34 in G-III. P values as follows: P < 0.001 of G-II/G-I; P < 0.005 of G-III/G-I and P < 0.0001 of G-III/G-II. We detected periarterial located taste buds like cell clusters and peripherally located ganglia connected with Langerhans cells via thin nerve fibers. There was an inverse relationship between the number of taste buds networks and blood glucose level. Conclusion: Newly described intrapancreatic taste buds may have an important role in the regulation of blood glucose level

A Novel Electrochemical Sensor for the Detection of Reactive Red Dye to Determine Water Quality

In this study, tragacanth gum/chitosan/ZnO nanoprism-based electrochemical sensors were prepared for sensing reactive dyes in water. To use an electrochemical sensor, a ~250 nm-sized ZnO nanoprism was synthesized via ultrasonic-assisted green synthesis method, using tragacanth gum and chitosan polymer blend as a matrix. The electrochemical properties of tragacanth gum/chitosan/ZnO nanoprisms were compared against reactive red 35, reactive yellow 15, and reactive black 194. The electrochemical measurement results indicated that prepared tragacanth gum/chitosan/ZnO nanoprism-based electrochemical sensor detected 25 ppm reactive red 35 in 1 min at room temperature. This study reveals new high-potential novel tragacanth gum/chitosan/ZnO nanoprism-based sensing material for the detection of reactive red dye-consisted wastewater with high sensitivity and short response time

Does intravenous lidocaine added to nonsteroidal anti-inflammatory drugs reduce pain during colposcopy? A prospective randomized double-blind study

Objectives: In recent years, lidocaine infusion for pain management during long operations is becoming more widespread in anesthesiology practice. However, only a limited number of studies have reported the intravenous use of lidocaine for short-term interventions. The aim of this study was to investigate the effectiveness of intravenous lidocaine use in pain management during colposcopic cervical biopsy and endocervical curettage (ECC). Material and methods: Patients between the ages of 18 and 65 years with abnormal cytological findings or who were determined to be human papillomavirus (HPV)-positive were included in this randomized double-blind study. The lidocaine group (Group L, n = 30) was intravenously administered 50 mg dexketoprofen + 1.5 mg/kg lidocaine in 10 mL saline for 3 min 30 min before the procedure. The control group (Group C, n = 30) was intravenously administered 50 mg dexketoprofen in 10 mL saline for 3 min, 30 min before the procedure. During the procedure, pain scores were assessed using the visual analogue scale (VAS). In addition, patients, operator satisfaction and duration of procedure were assessed Results: There were no differences in the demographic data of the groups. Pain scores during biopsy and ECC were significantly lower in Group L than in Group C (p < 0.001). The duration of the procedure was significantly shorter in Group L than in Group C (5.00 ± 0.78 vs 6.12 ± 1.16, respectively; p < 0.001). Patient and operator satisfaction were significantly higher in Group L than in Group C (p < 0.001). Conclusions: Intravenous lidocaine administration can be used as an alternative approach to reduce pain and increase operator and patient satisfaction during colposcopy-directed biopsy and ECC procedures in office settings

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Prozessentwicklung der induktiven Hochgeschwindigkeitsvergütung von Rotorwellen

Die verstärkte Nachfrage des Marktes nach regelbaren EC-Antrieben mit erhöhten Leistungsdichten fordert das Einsetzen von höherwertigen Elektroblechsorten. Diese weisen durch ihren höheren Siliziumgehalt höhere Härten auf, was zu neue Herausforderungen bei der Montage führt. Das Fügen sogenannter gekerbter Wellen in das Rotorlamellenpaket kann zu Partikelbildung führen, wenn die Härtedifferenz zwischen den beiden Fügepartnern zu gering ausfällt. Dieser Umstand ist zur Einhaltung der steigenden Anforderungen bezüglich technischer Sauberkeit zu vermeiden, da ansonsten kostspielige Reinigungskonzepte in der Montagelinie installiert werden müssen. Für die Montage von Lagern werden die Rotorwellen selektiv induktiv randschichtgehärtet. Hierbei müssen bspw. Lagerstellen eine Mindesthärte erreichen und Kerbzonen unbehandelt bleiben, damit eine entsprechende Umformbarkeit beim Kerben erhalten bleibt sowie der Verschleiß der Kerbwerkzeuge möglichst geringgehalten wird. Im Rahmen dieser Masterthesis wird die induktive Wärmebehandlung untersucht. Insbesondere wird hier das induktive Hochgeschwindigkeitsvergüten zur Weiterentwicklung der Welle-Nabe-Verbindung im Kerbbereich betrachtet, um bei gleichbleibender Taktzeit die erforderte Härtedifferenz zum Rotorlamellenwerkstoff zu ermöglichen. Hierbei wird der Kerbbereich wie für die Lagermontage induktiv randschichtgehärtet und anschließend bei höheren Temperaturen angelassen (vergütet). Die Auswertung der Versuchsergebnisse zeigt, dass mit dem vorhandenen Maschinenfuhrpark nur das Anlassen mit Selbstabschreckung die geforderten Härtetoleranzen als Kompromiss zwischen Spanfreiheit beim Fügen und Werkzeugverschleiß ermöglicht. Diese wiederum zeigen aufgrund der ununterbrochene Wärmeleitung eine in Axialrichtung ausgeweiteten Wärmeeinflusszone, die zu unscharfen Härteübergängen im Vergleich zu nach dem Anlassen aktiv gekühlter Rotorwellen führt. Eine höhere Härte in der Kerbzone führt zu einem kleineren Kerbaufwurf unter gleichbleibenden Kerbbedingungen. Der Nachweis einer Prozessfähigkeit für die Härte ist nicht üblich und kann auch aufgrund der hohen Unsicherheit des Härteprüfverfahrens nicht erbracht werden. Das Anlassen verschlechtert nur geringfügig den Rundlauf. Die Einpresskräfte von Rotorlamellenpaketen hängt von der Höhe des Kerbaufwurfs ab und steigt entsprechend mit deren Zunahme. Für eine serientaugliche Umsetzung ist in Abhängigkeit des Anforderungsprofils eine Rücksprache mit der Designabteilung bezüglich axiale Härteübergang und Kerbeindringtiefe notwendig. Für eine dauerhafte Lösung wird die Verwendung eines Mittelfrequenzgenerators für den Anlassprozess empfohlen
