The Effects of the Violence Tendency Levels of Nursing Students on Their Attitudes Towards Homosexual Individuals

BACKGROUND/AIMS: Nurses' attitudes towards homosexuality are an important factor affecting the quality of care given to homosexual individuals. Therefore, attitudes towards homosexual individuals and the variables affecting these attitudes should be investigated in the undergraduate period of nursing students. This study was conducted to determine the effects of the violence tendency levels of nursing students on their attitudes towards homosexual individuals.MATERIAL AND METHODS: This study used a cross-sectional and descriptive design. It was conducted with 502 nursing students at a state university. The data were collected using a student information form, the Hudson and Ricketts Homophobia Scale (HRHS) and the Violence Tendency Scale (VTS).RESULTS: The mean HRHS score of the students was 94.25 +/- 22.23, and their mean VTS score was 37.82 +/- 8.25. It was found that the students' attitudes towards homosexuals were related to their academic year, number of siblings, the region they lived in, and whether they live with their parents or not. Additionally, it was determined that the students' level of tendency towards violence was low, and low levels of violence tendency were related to higher levels of education of the mother ( p<0.05). There was no significant relationship between the students' violence tendency levels and their homophobia levels (R-2=0.001).CONCLUSION: It was determined that the nursing students' level of tendency towards violence was low, but their attitudes towards homosexuals were negative. Their level of tendency towards violence did not explain their attitude towards homosexuals significantly. These results showed that there are different factors affecting nursing students' homophobic attitudes

Time-Kill Kinetics and In Vitro Antifungal Susceptibility of Non-fumigatus Aspergillus Species Isolated from Patients with Ocular Mycoses

Aspergillus species can cause ocular morbidity and blindness, and thus, appropriate antifungal therapy is needed. We investigated the in vitro activity of itraconazole, voriconazole, posaconazole, caspofungin, anidulafungin, and amphotericin B against 14 Aspergillus isolates obtained from patients with ocular mycoses, using the CLSI reference broth microdilution methodology. In addition, time-kill assays were performed, exposing each isolate separately to 1-, 4-, and 16-fold concentrations above the minimum inhibitory concentration (MIC) of each antifungal agent. A sigmoid maximum-effect (Emax) model was used to fit the time-kill curve data. The drug effect was further evaluated by measuring an increase/decrease in the killing rate of the tested isolates. The MICs of amphotericin B, itraconazole, voriconazole, and posaconazole were 0.5–1.0, 1.0, 0.5–1.0, and 0.25 µg/ml for A. brasiliensis, A. niger, and A. tubingensis isolates, respectively, and 2.0–4.0, 0.5, 1.0 for A. flavus, and 0.12–0.25 µg/ml for A. nomius isolates, respectively. A. calidoustus had the highest MIC range for the azoles (4.0–16.0 µg/ml) among all isolates tested. The minimum effective concentrations of caspofungin and anidulafungin were ≤0.03–0.5 µg/ml and ≤0.03 µg/ml for all isolates, respectively. Posaconazole demonstrated maximal killing rates (Emax = 0.63 h−1, r2 = 0.71) against 14 ocular Aspergillus isolates, followed by amphotericin B (Emax = 0.39 h−1, r2 = 0.87), voriconazole (Emax = 0.35 h−1, r2 = 0.098), and itraconazole (Emax = 0.01 h−1, r2 = 0.98). Overall, the antifungal susceptibility of the non-fumigatusAspergillus isolates tested was species and antifungal agent dependent. Analysis of the kinetic growth assays, along with consideration of the killing rates, revealed that posaconazole was the most effective antifungal against all of the isolates

The Isolates of Bacteriuria and Fungiuria: Single Center Laboratory-Based 14-Year Analysis

Introduction: Developing and changing medical practices may cause a change in the frequency, variety and susceptibility of infection agents over years. Therefore, the analysis reports of the isolates in urinary tract infections (UTIs) will provide significant contributions to the correct management of these infections. We aimed to analyze the trends of frequency, distribution and antimicrobial susceptibility of agents isolated from urine cultures of both ambulatory patients and inpatients in this study. Materials and Methods: We evaluated the results of urine cultures for a 14-year period, retrospectively. Results: A total of 49.034 isolates from 46.626 culture positive nonrepetitive specimens were included. The most common isolate was E. coli (46.2%), followed by Enterococcus species (12.2%). Significant differences in species distribution were observed based on gender and the units where patients were treated, including ambulatory care, inpatient units, and intensive care units. The highest susceptibility rates for E. coli were observed with imipenem (≥99%) and amikacin (≥86%). The susceptibility of E. coli to cefazolin decreased over the years (from 70% to 32%). Enterococcus spp. were susceptible to vancomycin and linezolid with high rates (≥92% and ≥95%, respectively). A prominent decrease was observed in the susceptibility rate for Enterococcus spp. against ampicillin in years; from 94% to 68%. A continuous decreasing trend was detected in the susceptibility of Klebsiella spp. Conclusion: E. coli continues to be the most common urinary isolate. The distribution and frequency of isolates may show difference among centers and units. Continuous monitoring of antimicrobial susceptibility is important for accurate management of UTIs

Hipokalemik periyodik paralizi ile başlangıç gösteren primer Sjögren sendromu

Primer Sjögren sendromu (PSjS) heterojen klinik bulgularla seyreden kronik sistemik otoimmün bir hastalıktır. PSjS’de renal tutulum sıklığı %4.9 ve renal tutulum öncesi ortalama hastalık süresi iki yıl olarak bildirilmiştir. En sık renal tutulum tübülointerstisyel nefrit (TIN) olup daha az sıklıkla glomerülonefrit de görülebilmektedir. TIN bazı hastalarda izole elektrolit bozukluğu, distal renal tübüler asidoz (dRTA) yaparken bazı hastalarda ise son dönem böbrek yetmezliğine yol açabilmektedir (6). dRTA'un ise en sık klinik bulgusu hipokalemik paralizidir, bunun yanında nefrokalsinozis ve metabolik kemik hastalığına da yol açabilir. Bu yazıda PSjS’nin nadir bir başlangıç şekli olan renal tübüler asidoz ve hipokalemik periyodik paralizi olgusunu sunmaktayız.Primary Sjögren’s syndrome (PSjS) is a chronic systemic autoimmune disease with heterogeneous clinical findings. The incidence of renal involvement in PSjS was reported as 4.9% and the mean duration of disease before renal involvement was two years. The most common renal involvement is tubulointerstitial nephritis (TIN) and less frequent glomerulonephritis. TIN may lead to isolated electrolyte disorder and distal renal tubular acidosis (dRTA), while in some patients it may lead to end-stage renal failure (6). The most common clinical manifestation of DRTA is hypokalemic paralysis, which may lead to nephrocalcinosis and metabolic bone disease. We report a rare initial form of PSjS presenting with renal tubular acidosis and hypokalemic periodic paralysis

Lomber mikrodiskektomi operasyonundan sonra epidural tramadol infi ltrasyonu postoperative analjezik gereksinimini azaltır

Amaç: Çalışmanın amacı epidural tramadol infi ltrasyonunun postoperatif analjezik etkilerini araştırmak. Tramadol lokal anestezik ve antienfl amatuvar özellikleri de bilinen zayıf opioiddir. Yöntem ve gereç: Genel anestezi altında lomber mikrodiskektomi operasyonu geçiren ASA I veya II sınıfı 60 hasta çalışmaya alındı. Anestezi indüksiyonu 2-2.5 mg kg–1 propofol, 0.5 mg kg–1 roküronyum bromid, ve 1 ?g kg–1fentanil ile sağlandı. Anestezi idamesinde % 2-2,5 sevofl uran ve N2O/O2 (FiO2 = % 35) karışımı kullanıldı. Hastalar rastgele iki gruba ayrıldı. Çalışma grubunda operasyonun sonunda cerrahi saha kapanmadan önce epidural bölgeye 5 mL salin içinde 1 mg kg–1 tramadol verilirken, kontrol grubunda hastalara eşit volümde salin uygulandı. Ağrı vizüel analog skala (VAS) ile (0 ila 10 cm) her 4 saatte bir postoperatif ilk 24 saat boyunca değerlendirildi. Hasta kontrollü analjezi (HKA) cihazı 15 ?g fentanil bolus istek 10 dakika kilitli kalacak şekilde ayarlandı. Bulgular: Her iki grup arasında VAS değerleri açısından fark yoktu. Postoperatif ilk 24 saat fentanil tüketimi kontrol grubunda 328,5 ± 221,8 ?g ve tramadol grubunda 194,5 ± 147,4 ?g bulundu (P = 0,030). HKA bolus istek gereksinimi ise kontrol grubunda 51,2 ± 77,9 ve tramadol grubunda 20,1 ± 23,7 tespit edildi (P = 0,02). Yan etki profilleri arasında fark bulunmadı. Sonuç: Mikrodiskektomi operasyonu geçiren hastalarda epidural bölgeye uygulanan tramadol infi ltrasyonu analjezik gereksinimi belirgin ölçüde azaltmaktadır.Aim: To investigate the postoperative analgesic effects of epidural tramadol infi ltration. Tramadol is a weak opioid that has local anesthetic and antiinflammatory properties. Materials and methods: Sixty patients of American Society of Anesthesiologists class I or II undergoing lumbar microdiscectomy with general anesthesia were included in the study. The induction of anesthesia was performed with propofol (2-2.5 mg kg–1), rocuronium bromide (0.5 mg kg–1), and fentanyl (1 &amp;#956;g kg–1). A sevofl urane and N2O/O2 (FiO2 = 35%) mixture was used for maintenance. Patients were randomly divided into 2 groups. Tramadol (1 mg kg–1) in a 5-mL saline epidural infiltration was given in the study group at the end of the operation, before surgical closure, and saline in the same volume was given to the control group. Pain was assessed by a visual analog scale (0 to 10 cm) at 4-h intervals during the first postoperative 24 h. A patient-controlled analgesia (PCA) device was adjusted to deliver fentanyl (15 &amp;#956;g bolus) on demand, with a 10-min lockout interval. Results: No significant difference was found in the visual analog scales between the groups. Tramadol infiltration significantly decreased fentanyl consumption in the first 24 h (fentanyl dose in the control group: 328.5 &plusmn; 221.8 &amp;#956;g, tramadol group: 194.5 &plusmn; 147.4 &amp;#956;g, P = 0.030). The number of demands for PCA were 51.2 &plusmn; 77.9 and 20.1 &plusmn; 23.7 in the control and the tramadol groups, respectively (P = 0.02). No difference was found in side-effect profiles between the groups. Conclusion: Tramadol administration to the epidural space significantly decreased analgesic consumption in patients undergoing microdiscectomy
