Article Investigation of the Susceptibility Rates to Ceftazidime-Avibactam and Colistin, Clonal Relationships, and Clinical Data of Patients with Carbapenem-Resistant Klebsiella Pneumoniae Isolates Detected in the ICUs of a Hospital in İstanbul(K Faisal Special Hospital Research Centre, 2026) Akkaya, Yuksel; Aydin, Irfan; Harmankaya, Sebile; Karakul, Mehmet; Aydin, Mehtap; Erdin, Begum Nalca; Kilic, Ibrahim Halil; Karakuş, MehmetBACKGROUND: The increase in carbapenem-resistant K. pneumoniae (CR-Kp) in intensive care units (ICUs) causes treatment difficulties and increases risk in mortality. OBJECTIVES: The aim of this study was to investigate the susceptibility rates of CR-Kp isolates obtained from ICUs to ceftazidime-avibactam (CAZ-AVI) and colistin, carbapenem resistance genes, clonal relationships and clinical characteristics of the patients. DESIGN: Retrospective cohort SETTING: Single-center, University of Health Sciences, & Uuml;mraniye Training and Research Hospital MATERIALS AND METHODS: This study was conducted between June 2023 and December 2024. Isolates were identified using VITEK MS v.3.2, and antibiotic susceptibility testing was performed using the VITEK 2 Compact system. CAZ-AVI susceptibility was determined using disk diffusion, and colistin susceptibility was determined using broth microdilution to determine minimum inhibitory concentration (MIC) values. Carbapenem resistance genes were determined using multiplex real-time polymerase chain reaction (RT-PCR) and clonal relationship arbitrarily primed-polymerase chain reaction (AP-PCR). MAIN OUTCOME MEASURES: Resistance genes of CR-Kp isolates, clonal relationships, CAZ-AVI and colistin resistance, and clinical characteristics of patients SAMPLE SIZE: Ninety-seven isolates from 76 patients RESULTS: Among patients with CR-Kp isolates, central venous catheter use was detected in 59 cases (78%), ventilator-associated pneumonia in 44 cases (58%), and bacteremia in 39 cases (51%), respectively. It was determined that 53 of the patients (70%) died. Using the AP-PCR method, 60 different genotypes were identified among 97 isolates, and clustering was determined in 42 of the isolates (46%). It was determined that 36 (37%) of the isolates were resistant to colistin and 42 (45%) were resistant to CAZ-AVI. NDM+OXA-48, OXA-48, KPC, KPC+NDM, and NDM genes were detected in 40 (43%), 32 (35%), 10 (11%), 2 (2%), and 3 (3%) isolates, respectively. It was determined that 30 (75%) of the isolates with NDM+OXA-48 and only 4 (12%) of the isolates with OXA-48 were resistant to CAZ-AVI. CONCLUSION: In addition to OXA-48, an increase in the frequency of CR-Kp isolates containing the NDM, NDM+OXA-48, KPC+NDM, and OXA-48+KPC genes were also detected. It was also determined that resistance to colistin and CAZ-AVI is increasing. The AP-PCR method can also be used to investigate infections.

Complicated diverticulitis (CD) mostly requires hospitalization and can be treated within a spectrum from observation to surgery. Treatment choice is formed depending on the patient's general condition, the presence of diffuse peritonitis, the localization of diverticulitis, Hinchey stage, and responsiveness to the prior treatment. Clinical disparities regarding right and LCD also led to the differences in the incidences of both emergency surgery and future elective surgery. AIM To evaluate the clinical features of CD, display the differences according to colonic localizations, and present treatment approaches. METHODS This was a retrospective study from a single centre analysing data from a prospective database. The 253 patients with history of hospitalization for CD were included and divided into two groups: RCD and LCD. To compare the differences between the two groups, the Student's t-test was used when the parametric test prerequisites were fulfilled, and the Mann-Whitney U test was used when such requirements were not fulfilled. RESULTS The 208 (82.2%) patients were found to have LCD, and 45 (17.8%) had RCD. The majority of the patients had Hinchey 1A diverticulitis (49.8%). Male gender was significantly more common in patients who underwent surgery for LCD. While persistent abdominal pain was the main prior finding in the conservative treatment of both localizations, surgery was most performed due to abscess in RCD and perforation in LCD. The presence of an accompanying malignancy during colonoscopy was significantly more common in LCD cases who underwent surgery. Hartmann's procedure was the most performed technique in emergency settings (56.3%), while laparoscopic colectomy with anastomosis was in elective settings (53.9%). In addition, surgery was found to prolong the mean length of hospital stay in LCD patients. CONCLUSION Although diverticulitis is a benign condition, the need for an individualized and evidence-based approach makes management challenging. Localization of the disease has an important role in determining the appropriate treatment.Article Citation - WoS: 1Safety and Efficacy of Depatuxizumab Mafodotin Monotherapy or in Combination With Temozolomide in Patients With/Without EGFR-Amplified Recurrent Glioblastoma: A Systematic Review(Lippincott Williams & Wilkins, 2025) Moghib, Khaled; Hassan, Malak A.; Eljadid, Ghaith Y.; Salomon, Izere; Algazar, Mansour A.; Abu Arafeh, Muhannad Wael; Ibrahim, Ismail A.This study aimed to assess the safety and efficacy of depatuxizumab mafodotin as a monotherapy or in combination with temozolomide in patients with recurrent epidermal growth factor receptor (EGFR)-amplified glioblastoma multiforme, focusing on overall survival (OS) and progression-free survival (PFS). A comprehensive literature search was conducted across PubMed, Cochrane Library, Web of Science, and Scopus databases up to August 2024. Randomized controlled trials (RCTs) and observational studies were included, comparing depatuxizumab mafodotin alone or with temozolomide in patients with and without EGFR amplification. Data extraction encompassed participant demographics, treatment regimens, and clinical outcomes. Of 102 screened publications, 10 RCTs and cohort studies involving 1431 patients met the inclusion criteria. The included studies examined depatuxizumab mafodotin as a standalone therapy and in combination with other agents, revealing OS ranging from 5 to 14 months and considerable variability in PFS. While depatuxizumab mafodotin shows the potential to improve survival outcomes, the heterogeneity in results highlights the need for further research. Future studies should refine patient selection criteria and explore alternative therapeutic combinations, such as depatuxizumab mafodotin with gemcitabine or cisplatin, to optimize treatment strategies.Article Citation - WoS: 1Technical Approaches for Preservation of the Temporalis Muscle in Neurosurgery: A Systematic Review(Lippincott Williams & Wilkins, 2025) Azab, Mohammed A.; Sarhan, Khalid; Atallah, Oday; Hernandez-Hernandez, Alan; Ibrahim, Ismail A.; Shama, Mohsen Nabih; Kammoun, BrahimBackground:The temporalis muscle is commonly dissected and mobilized during craniotomy. Cosmetic and functional complications may arise from the improper handling of this muscle. Surgery for recurrent pathologies may be challenging due to adhesions and muscle damage.Material and methods:A systematic review following PRISMA guidelines was conducted to consolidate literature on the potential techniques used for preserving the temporalis muscle during neurosurgical interventions. PubMed, Scopus, and Web of Science were systematically searched using predefined criteria from inception to 2025. A qualitative synthesis was done summarizing the primary cranial pathology, type of surgical approach, the technical clue for temporalis muscle preservation, follow up and complications.Results:We included 27 eligible articles with a total number of 811 patients. About 508 (62.6%) of patients underwent pterional approach, while 150 (18.4%) patients had decompressive craniotomies. Aneurysm clipping was the surgical indication in 172 (21.2%) patients, while decompressive surgery was done for traumatic brain injuries in about 48 (5.9%) patients. Osteoplastic temporalis muscle flap was used in 178 (21.9%) patients, while some authors sutured the temporalis muscle to the cranioplasty plate in 79 (9.7%) patients. Fixation of the temporalis muscle to the bone using sutures through small holes was done in 100 (12.33%) patients. No chewing problems were recorded among all the patients analyzed. Temporalis muscle atrophy was observed in only 13 (1.6%) patients.Conclusion:Proper manipulation of the temporalis muscle during surgery is crucial for the vitality of its fibers and to prevent postoperative functional or cosmetic drawbacks.Article Citation - WoS: 3Need To Address the Gender Disparities in Neurosurgery in India(Lippincott Williams & Wilkins, 2024) Anand, Ayush; Ibrahim, Ismail A.; Kathayat, Priyangi; Ansari, Ayesha; Aggarwal, Yash; Wahi, Riddhpreet Kaur; Rustagi, Sarvesh[No Abstract Available]Article Citation - WoS: 3Qualitative and Artificial Intelligence-Based Sentiment Analysis of Turkish Twitter Messages Related To Autism Spectrum Disorders(Springernature, 2023) Göksel, Pelin; Oban, Volkan; Dikec, Gul; Usta, Mirac BarisBackground: The aim of our study was to conduct an emotional analysis of Turkish Twitter messages related to autism spectrum disorders (ASD). Methods: An emotion analysis was performed using quantitative and qualitative analysis methods on Turkish Twitter messages shared between November 2021 and January 2022 that contained the words "autism" and "autistic." Results: It was found that 81.5% of the 13,042 messages that constituted the sample of this study contained neutral emotions. The most frequently used words in Twitter messages were autism, a, universe, strong, patience, warriors, and happy. The qualitative analysis revealed three main themes. These themes were: "experiences," "informing society and awareness," and "humiliation." Conclusion: In this study, it was found that Turkish Twitter messages related to autism, which were analyzed using artificial intelligence-based emotion analysis, often contained neutral emotions. While the content of these messages, often shared by parents, was related to experiences, and the messages shared by pediatric psychiatrists and rehabilitation center employees were informative in nature, it was determined that the word "autism" was used to insult, which is outside of its medical meaning.Article Citation - WoS: 3Nipah Virus Transmission: a Persistent Threat To Public Health Demanding Rapid Diagnosis, Innovative Therapeutics, Vigilance, and Research Progress(Lippincott Williams & Wilkins, 2024) Islam, Md. Aminul; Ibrahim, Ismail A.; Hemo, Mizbahul Karim[No Abstract Available]Article Citation - WoS: 4Effect of Multileaf Collimator Leaf Position Error Determined by Picket Fence Test on Gamma Index Value in Patient-Specific Quality Assurance of Volumetric-Modulated Arc Therapy Plans(Springernature, 2021) Ceylan, Cemile; Inal, Serpil Yondem; Senol, Elif; Yilmaz, Berrin; Sahin, SevimAim The correlation between the MLC QA (IBA Dosimetry, Germany) results of the picket fence test created with intentional errors and the patient's quality assurance (QA) evaluation was investigated to assess the impact of multileaf collimator (MLC) positioning error on patient QA. Materials and methods The picket fence, including error-free and intentional MLC errors, defined in Bank In, Bank Out, and Bank Both were analyzed using MLC QA. The QA of 15 plans consisting of stereotactic radiosurgery (SRS), stereotactic body radiotherapy (SBRT), and conventionally fractionated volumetric-modulated arc therapy (VMAT) acquired with electronic portal imaging devices (EPID) was evaluated in the presence of error-free and MLC errors. The QA of plans were analyzed with 2%/2 mm and 3%/3 mm criteria. Results The passing rates of the picket fence test were 97%, 92%, 91%, and 87% for error-free and intentional errors. The criterion of 3%/3 mm wasn't able to detect an MLC error for either SRS/SBRT or conventionally fractionated VMAT. The criterion of 2%/2mm was more sensitive to detect MLC error for the conventionally fractionated VMAT than SRS/SBRT. While only two of SBRT plans had <90%, four of conventionally fractionated VMAT plans had a <90% passing rate. Conclusion We found that the systematic MLC positioning errors defined with picket fence have a smaller but measurable impact on SRS/SBRT than the VMAT plan for a conventionally fractionated and relatively complex plan such as head and neck and endometrium cases.Article Citation - WoS: 10Assessment of the Effectiveness of Patient Education and Interviews in Improving Medication Adherence of Renal Transplant Recipients(Springernature, 2022) Aksit, Naile; Ozbas, Ayfer; Akinci, SerkanBackground Non-compliance with immunosuppressive drugs has been reported as the most significant cause of graft loss. Since non-compliance with immunosuppressive drugs is preventable, certain approaches based on the risk factors and causes of non-compliance can help eliminate this problem. Aims The purpose of this study is to assess the effectiveness of patient education and interviews in improving medication adherence of renal-transplant recipients. Materials and methods This study was designed as a randomized controlled trial. Using the G*Power program, the sample size was calculated as 60 subjects, with 30 in both the intervention group and control group. Data collection tools included a patient information form, a pretest-posttest, a drug monitoring form for kidney transplant patients, the Immunosuppressive Therapy Adherence Scale, measurement of tacrolimus blood levels, and a training booklet. Results The mean knowledge score in the intervention group was 12.17 +/- 3.39 at baseline, and it increased to 20.73 +/- 1.57 after the intervention. The mean scores on the Immunosuppressant Therapy Adherence Scale were 11.67 +/- 0.55 and 10.70 +/- 0.99 in the intervention group and control group, respectively. There was a statistically significant difference between the pre- test and post-test means on the Immunosuppressant Therapy Adherence Scale in the intervention group. The mean Immunosuppressant Therapy Adherence Scale score was higher in the intervention group. In the measurement of tacrolimus blood levels, medication adherence was found the be higher in the intervention group. The difference between the groups was statistically significant. There was a positive correlation between the tacrolimus blood levels and the Immunosuppressant Therapy Adherence Scale scores in both groups. Conclusions To conclude, our results have demonstrated that patient education and interviews improve immunosuppressant medication adherence in renal transplant recipients. Using direct or indirect methods proved similar outcomes, suggesting that both evaluation methods are safe.
