    Effect of topical application of black pepper essential oil on peripheral intravenous catheter insertion: A randomized controlled study
    (Elsevier Inc., 2021) Eren, Handan; Türkmen, Ayşe Sonay; Aslan, Ahmet
    Objective: The literature describes many techniques to increase vein visibility and palpability that facilitate peripheral intravenous catheter insertion. However, there is only one study examining the effect of topical essential black pepper oil on veins. We aimed to determine the effects of topical application of black pepper essential oil on peripheral intravenous catheter insertion success. Methods: This randomized controlled trial was carried out on 60 patients randomly assigned to either the experimental group (n=30) or the control group (n=30) reporting to the endoscopy unit of the clinic between May 2019 and October 2019. The study results were evaluated using an information form, a catheter insertion form, and a visual analog scale (VAS). In the experimental group, black pepper essential oil was used to increase vein degree before the procedure, while in the control group, no extra interventions were applied. The time taken in determining an appropriate vein, time taken for successful catheter insertion, and the patient's and nurse's satisfaction after the process were recorded. Results: Significant improvements in vein degree were detected after the experimental group's oil application (p1<0.001). The period of appropriate vein selection and successful catheter insertion showed a statistically significant decrease in the experimental group (p<0.05). The satisfaction levels of patients and nurses in the control group were significantly lower than those of the patients from the experimental group (p<0.05). Conclusion: Topical black pepper oil application can increase the vein degree and the success of the procedure.

    Factors affecting physician fear of malpractice and defensive medicine practices: A cross-sectional study
    (2024) Özdemir, Rana Can; Işık, Meryem Türkan; Aslan, Ahmet; Ayaz, Merih
    Objective: The aim of this study was to determine the attitudes of a group of physicians toward defensive medicine, their fears of malpractice and the affecting factors. Methods: Data was collected between April and July 2022 in this cross-sectional study. The sample size was 248 physicians. Data was collected using the Defensive Medicine Attitude Scale and Malpractice Fear Scale. Data was analyzed using frequency tables, descriptive statistics, Mann-Whitney U test (Z-table value) and the Kruskal-Wallis H test (?2-table value). Results: Most participants 99.2% (n=246) thought that a doctor’s professional liability insurance should be taken out and 72.6% (n=180) avoided giving treatment to difficult patient groups. In our study, the mean score on the Defensive Medicine Attitude Scale was moderate (32.12±6.12), and the mean score on the Malpractice Fear Scale was high (24.31±2.86). A weak positive correlation was found between the Malpractice Fear Scale score and the scores for positive defensive medicine, negative defensive medicine, avoidance, and the Defensive Medicine Attitude Scale total score (p<0.05). Conclusion: Our study determined that the fear of malpractice increased the tendency toward defensive medicine practice. Most physicians adopted the defensive behavior in medicine and were afraid of facing malpractice lawsuits in near future.

    Trace element levels in serum and gastric mucosa in patients with Helicobacter pylori positive and negative gastritis
    (Elsevier GMBH, 2022) Aslan, Ahmet; Karapınar, Hacer Sibel; Kılıçel, Fevzi; Pekin, Ceyhun; Toprak, Şükrü Salih; Boyacıoğlu, Tülin; Cihan, Mehmethan; Yılmaz Sanal, Burcu
    Background: Most trace elements are inhibited by Helicobacter pylori-infection, and variations in specific element levels are linked to the development of stomach cancer. This is the first study to show the relationship between serum and tissue concentrations of twenty-five trace elements and H. pylori infection status. This study purposed to define serum and tissue trace element levels of 25 healthy individuals with Helicobacter pylori-positive gastritis and Helicobacter pylori-negative gastritis and to reveal their relationship with the disease. Methods: Study groups consisted of sixty-two patients with Helicobacter pylori-positive, thirty-seven patients with Helicobacter pylori-negative, and thirty healthy individuals. Serum and tissue concentrations of twenty-five elements (aluminum, boron, arsenic, barium, calcium, beryllium, copper, cadmium, iron, chromium, mercury, lithium, potassium, magnesium, sodium, manganese, nickel, phosphorus, lead, scandium, strontium, selenium, tellurium, titanium, zinc) were defined by inductively coupled plasma optical emission spectrometry. Results: Except for copper, lithium, and strontium elements in serum samples, other trace elements differed significantly between the groups (p < 0.05). The serum chromium (p = 0.002), mercury (p = 0.001), boron (p < 0.001), and cadmium (p < 0.001) levels of H. pylori-negative gastritis and H. pylori-positive gastritis participants were significantly different, and their serum concentrations were less than 0.5 µ/l. Boron, barium, beryllium, chromium, lithium, phosphorus and strontium elements in tissue samples did not differ significantly between the groups (p > 0.05). Manganese, nickel, tellurium and titanium elements were not detected in tissue and serum samples. The mean concentrations of calcium, beryllium, chromium, iron, potassium, lithium, magnesium, scandium, and selenium were higher in the tissues of patients with H. pylori gastritis compared to healthy control tissues. Also, cadmium could not be detected in tissue samples. There was a significant difference between H. pylori-infected tissue and serum chromium levels (p = 0.001), with lower levels detected in tissue samples. Conclusion: This is the first study that we are knowledgeable of that reports the concentrations of twenty five elements in both serum and tissue samples, as well as the relationship between trace elements and Helicobacter pylori-infection status. Dietary adjustment is indicated as an adjunct to medical therapy to stabilize trace elements because Helicobacter pylori bacteria cause inflammation and impair element absorption in gastritis patients. We also think that this study will shed light on studies on the relationship between Helicobacter pylori-trace elements and serum-tissue/healthy serum-tissue trace element levels of patients with Helicobacter pylori gastritis.
