Öğe Acute peripancreatic fluid collection in acute pancreatitis: Incidence, outcome, and association with inflammatory markers(Wolters Kluwer Medknow Publications, 2023) Solakoglu, Tevfik; Kucukmetin, Nurten; Akar, Mustafa; Koseoglu, HueseyinBackground: The hospital outcomes and predictors of acute peripancreatic fluid collection (APFC) have not been well-characterized. In this study, we aimed to investigate the clinical outcomes of APFC in patients with acute pancreatitis (AP) and the role of the systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), and C-reactive protein (CRP) level in predicting the occurrence of APFC. Methods: In this retrospective study, the complicated group (patients with APFC) and the uncomplicated group (patients without APFC) were compared for their clinical characteristics, hospital outcomes (mortality rate, intensive care unit admission rate, and length of hospital stay), pseudocyst formation, CRP levels, SII, and SIRI on admission and at 48 hours. Results: Of 132 patients with AP, 51 (38.6%) had APFC and eight (6.1%) had pancreatic pseudocysts. Of 51 patients with APFC, 15.7% had pancreatic pseudocysts. Pseudocyst did not develop in the uncomplicated group. SII value at 48 h [median 859 (541-1740) x 109/L vs. 610 (343-1259) x 109/L, P = 0.01] and CRP level at 48 h [89 (40-237) mg/L vs. 38 (12-122) mg/L, P = 0.01] were higher in the complicated group than in the uncomplicated group. The length of hospital stay was longer in the complicated group, compared with the uncomplicated group [median 8 days (5-15), vs. 4 days (3-7), P < 0.001, respectively]. No significant difference was detected between the two study groups' mortality rates and intensive care unit admission rates. Conclusions: While 38.6% of the AP patients had APFC, 6.1% of all patients and 15.7% of the patients with APFC had pancreatic pseudocysts. APFC was found to lengthen the hospital stay and to be associated with the SII value and CRP level measured at 48 h.Öğe Autoimmune hepatitis as an overlap of secondary antiphospholipid syndrome(2021) Baran, Bilge Saka; Ersoy, Osman; Akar, Mustafa; Solakoğlu, Tevfik[Asbtract Not Availavle]Öğe Clinical relevance of virulence genes in Helicobacter pylori isolates recovered from adult dyspeptic patients in Turkey(Elsevier, 2022) Akar, Mustafa; Kayman, Tuba; Abay, Seçil; Solakoğlu, Tevfik; Karakaya, Emre; Aydın, FuatPurpose: Bacterial virulence factors play a major role in the pathogenesis of Helicobacter pylori infection. The aims of this study were to evaluate virulence genes in H. pylori isolates and to compare the presence of these genes and associated clinical pathologies. Methods: A total of 148 H. pylori isolates, recovered from adult dyspeptic patients, were used. The patients, from whom the isolates were obtained, were assigned to two groups by their endoscopic findings, which manifested as chronic gastritis or peptic ulcer. The presence of gastric atrophy and intestinal metaplasia was recorded for each patient, based on histopathological examination. Analyses of the virulence genes were performed by the polymerase chain reaction technique. Results: The patients had a mean age of 47 ?? 15 years and 86 (58%) of them were female. Based on endoscopic examination, 103 (69.6%) patients were diagnosed with chronic gastritis and 45 (30.4%) with peptic ulcer. Histopathological examination revealed intestinal metaplasia in 30 (20%) patients and gastric atrophy in 12 (8%) patients. The prevalence rates of cagA, cagE, iceA1, iceA2, and babA2 were determined to be 87%, 74%, 58%, 26%, and 95%, respectively. The most prevalent vacA alleles were s1/s1a (82%/97%) and the least prevalent allele was s2 (20%). A new vacA genotype (s1as1bs1c) was detected, for the first time, in 18 (12%) isolates. No significant difference was found between the patient groups with chronic gastritis and peptic ulcer for the prevalences of the virulence genes (p > 0.05). Furthermore, intestinal metaplasia and gastric atrophy showed no significant correlation with the virulence genes (p > 0.05). Conclusions: It is thoughted that H. pylori isolates with predominant cagA, cagE, VacA (s1, s1a), and babA2 virulence genes are associated with gastroduodenal diseases. However, there is no correlation between gastric premalignant lesions and virulence genes.Öğe Effect of Direct-acting Oral Anticoagulants and Warfarin on Hospital Outcomes in Upper Gastrointestinal Bleeding(College of Physicians and Surgeons Pakistan, 2022) Solakoğlu, Tevfik; Köseoğlu, Hüseyin; Küçükmetin, Nurten Türkel; Akar, Mustafa; Mete, RafetObjective: To evaluate the comparison of direct-acting oral anticoagulants (DOACs) and warfarin for their effects on major bleeding and hospital outcomes in patients with acute nonvariceal upper gastrointestinal bleeding (NVUGIB). Study Design: An observational study. Place and Duration of Study: Tekirdag Namik Kemal University Hospital, Hitit University Erol Olçok Education and Research Hospital, between January and December 2021. Methodology: Adult patients prescribed warfarin and DOACs were followed up for one year. Their length of hospital stay, need for intensive care unit admission, need for red blood cell transfusion, and major bleeding rates were compared. Results: Thirty-two patients (61.5%) were user of DOACs (DOAC group), and 20 patients (38.5%) were users of warfarin (warfarin group). No statistically significant difference was determined between patients in warfarin group and DOAC group for the number of packed red blood cells transfused [median 3 (0-6) units, 3 (0-10) units, p=0.229, respectively], length of hospital stay [median 5 days (3-10), and 4.5 days (2-20), p=0.739, respectively], rate of intensive care unit admission [(n=9, 45%; and n=10 (31%), p=0.623, respectively] and the occurrence of major bleeding events (warfarin-70%; DOACs-78%; p=0.529). Conclusion: Major bleeding episodes and hospital outcomes of acute NVUGIB were similar between patients receiving warfarin and DOACs. © 2022 College of Physicians and Surgeons Pakistan.

The study consisted of 75 patientswith CRC and 91 study participants with normal colonoscopy as control group, and MPV and NLR were compared between groups.MPV and NLR were also investigated for tumor stage and metastasis.Results: Among the CRC patients the mean NLR value (3.09 vs 2.26) and PLT count (287080 vs 251857) were significantly higher,whereas the mean MPV (9.62 vs 10.68 fL) and hemoglobin level (11.62 vs 14.18 g/dl) were significantly lower in the CRC group. WBCcount was not significantly different between the groups. Mean NLR in metastatic patients and non-metastatic patients were 3.56and 2.73, respectively (p:0.01).Conclusion: We showed that high NLR and low MPV are associated with CRC. Elevated NLR is related with presence of CRC and itcan be used for risk prediction. Although we found lower MPV levels, conflicting results about MPV in CRC prevents it from using asa marker in CRC.Öğe Two novel sequence types of Helicobacter pylori strains: The first report from Turkey(Wiley, 2022) Akar, Mustafa; Satıcıoğlu, İzzet Burçin; Karakaya, Emre; Kayman, Tuba; Abay, Seçil; Solakoğlu, Tevfik; Aydın, Fuat[No Abstract Available]
