Effect of Lateral Thinking Dispositions on Groupwork
No full textThe aim of this study is to compare the effect of lateral thinking dispositions on groupwork in a collaborative learning environment from different angles as quantitatively and qualitatively in line with methodological pluralism. The population of the study included freshmen students studying Gastronomy and Culinary Arts in Tourism Faculty of a state university. The study was conducted in three samples within the scope of methodological pluralism including data triangulation (for SPSS analysis: N = 83- all the students in the study universe-; for thematic analysis: N = 66- selected on a voluntary basis depending on voluntary response sampling-; and for the Rasch analysis: N = 16 students accepting to participate this aspect of the study voluntarily and 3 faculty members who have the responsibilities of the groupwork of the students). In the quantitative phase, descriptive analysis was performed through the Rasch Measurement Model and SPSS program while in the qualitative part of the study, the case study approach was conducted under the checklist of COREQ Statement. Rasch results indicated the LATD (Lateral Thinking Dispositions) scores of the students graduating from tourism or cooking related vocational high schools and having work experience were higher than their counterparts not graduating from tourism related high schools and had no work experience beforehand. Qualitative results showed consistency with the quantitative results. Teachers are suggested to be trained so that lateral thinking skills can be implemented in class environment
Rapid diagnosis of catheter related sepsis in hemodialysis patients
No full textPurpose: To distinguish between infected and non-infected Central Venous Catheters (CVCs) applied to hemodialysis patients without having to wait bacterial cultures, we evaluated the importance of sera C-Reactive Protein (CRP) test results to diagnose Catheter Related Sepsis (CRS) and compared this test with microbiologic cultures. Patients and Methods: Fifty-eight hemodialysis patients (16 Acute Renal Failure and 42 Chronic Renal Failure) and 81 CVCs applied to these patients were followed up. Twenty-six (45%) were female, 32 (55%) male, and the mean age was 46 (SD: 15; range: 15-70) years. When CRS was clinically suspected, catheters were removed and catheter tips cultured using semiquantitative method, or simultaneously blood samples were taken from catheters and peripheral vein for blood cultures. At the same time, peripheral blood samples were taken and sera CRP levels were tested with semiquantitative latex method. Results: Forty suspected and microbiologically confirmed CRS episodes were detected in two year follow up period. The sera CRP test was 95% sensitive and 78% specific (accepted 12 mg/L and higher levels as a CRS) in the diagnosis of microbiologically defined CRS. Conclusion: Results are available in minutes, using CRP test there fore fewer CVCs may have to be removed on suspicion of CRS in hemodialysis patients
Genitourinary brucellosis: results of a multicentric study
No full textThis study reviewed the clinical, laboratory, therapeutic and prognostic data on genitourinary involvement of brucellosis in this largest case series reported. This multicentre study pooled adult patients with genitourinary brucellar involvement from 34 centres treated between 2000 and 2013. Diagnosis of the disease was established by conventional methods. Overall 390 patients with genitourinary brucellosis (352 male, 90.2%) were pooled. In male patients, the most frequent involved site was the scrotal area (n=327, 83.8%), as epididymo-orchitis (n=204, 58%), orchitis (n=112, 31.8%) and epididymitis (n=11, 3.1%). In female patients, pyelonephritis (n=33/38, 86.8%) was significantly higher than in male patients (n=11/352, 3.1%; p<0.0001). The mean blood leukocyte count was 7530 +/- 3115/mm(3). Routine laboratory analysis revealed mild to moderate increases for erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). The mean treatment duration and length of hospital stay were significantly higher when there were additional brucellar foci (p<0.05). Surgical operations including orchiectomy and abscess drainage were performed in nine (2.3%) patients. Therapeutic failure was detected in six (1.5%), relapse occurred in four (1%), and persistent infertility related to brucellosis occurred in one patient. A localized scrotal infection in men or pyelonephritis in women in the absence of leucocytosis and with mild to moderate increases in inflammatory markers should signal the possibility of brucellar genitourinary disease
Antimicrobial susceptibility of Bacillus anthracis in an endemic area
No full textWe aimed to test the antimicrobial susceptibility of 28 Bacillus anthracis strains isolated from cutaneous anthrax cases to various antimicrobial agents using the Sceptor automatic system in an anthrax endemic area. All strains tested were susceptible to penicillin (MIC less than or equal to 0.03 mug/ml). Piperacillin-tazobactam and carbapenems showed good activity towards all strains. Trimethoprim-sulfamethoxazole and cefepime had no activity. Strains were also tested with other antimicrobials
Effects of giardiasis on school success, weight and height indices of primary school children in Turkey
No full textBackground: Giardia intestinalis, the most common parasite in the world, causes several adverse effects on school children, with the prevalence rate ranging between 7.3% and 28% (mean 13.8%) in Turkey. The aim of the present study was to investigate possible adverse effects of G. intestinalis on success at school, and the mean weight and height of primary school children in Sivas, Turkey. Methods: Five primary schools from central Sivas, Turkey, had a number of students from different socioeconomic conditions and regions. The stool specimens were examined by light microscopy for giardiasis using saline-Lugol and/or zinc sulfate flotation method. Three groups in the present study include the symptomatic giardiasis group (SG), which included children with giardiasis along with abdominal pain and/or diarrhea, the asymptomatic giardiasis group (ASG) without any symptom and the non-parasitic (NPG) group without any parasites. Results: While 599 (34.6%) out of 1730 children were parasitic, 192 (11.1%) had only G. intestinalis. Ninety-eight (5.7%) of 192 were SG (with diarrhea and/or abdominal pain and 94 (5.4%) were ASG. The weights and heights were lower in the children with giardiasis than the children without any parasite. There was a significant difference between the giardiasis group and NPG when the numbers of persons living in the house were compared. While there were no significant difference between the giardiasis group and NPG when the sexes were compared, success at school and economical levels were found to be significantly different between these groups. Conclusion: There was a higher prevalence of giardiasis in primary school children and their physical and mental conditions were affected adversely. Giardia infections in particular have adverse effects on success at school
Pancreatic pseudotumor due to peripancreatic tuberculous lymphadenitis
No full textPeripancreatic tuberculous lymphadenitis is a very rare and difficult diagnosis. We report herein a patient with a clinically solitary abdominal tuberculoma. A 68-year-old woman was admitted to our hospital with moderate-level obstructive jaundice due to a mass located between pylorus and head of the pancreas. There were no clinical signs or symptoms of tuberculosis in lungs or abdomen. After the diagnosis of a neoplasm of the pancreas was made, exploratory laparotomy was performed which revealed a conglomerated mass penetrating into the pancreas. Since an exact diagnosis could not be reached on the basis of frozen sections prepared during the operation, a standard Whipple procedure was performed. After the histopathological examination of the resected specimen revealed tuberculous lympadenitis, the patient was given antituberculous medication. The patient recovered well. An abdominal tuberculoma is often mistaken for a malignant neoplasm, and nonsurgical diagnosis and treatment of this entity continues to be a challenge. Copyright (C) 2002 S. Karger AG, Basel and IAP
Crimean–Congo haemorrhagic fever virus uses LDLR to bind and enter host cells
No full textClimate change and population densities accelerated transmission of highly pathogenic viruses to humans, including the Crimean–Congo haemorrhagic fever virus (CCHFV). Here we report that the Low Density Lipoprotein Receptor (LDLR) is a critical receptor for CCHFV cell entry, playing a vital role in CCHFV infection in cell culture and blood vessel organoids. The interaction between CCHFV and LDLR is highly specific, with other members of the LDLR protein family failing to bind to or neutralize the virus. Biosensor experiments demonstrate that LDLR specifically binds the surface glycoproteins of CCHFV. Importantly, mice lacking LDLR exhibit a delay in CCHFV-induced disease. Furthermore, we identified the presence of Apolipoprotein E (ApoE) on CCHFV particles. Our findings highlight the essential role of LDLR in CCHFV infection, irrespective of ApoE presence, when the virus is produced in tick cells. This discovery holds profound implications for the development of future therapies against CCHFV
