Objectives: To assess the appropriateness and readability of large language model (LLM) chatbots' answers to frequently asked questions about refractive surgery.
Materials And Methods: Four commonly used LLM chatbots were asked 40 questions frequently asked by patients about refractive surgery. The appropriateness of the answers was evaluated by 2 experienced refractive surgeons.
Article Synopsis
- The study aimed to compare the effects of superior (SI) and temporal (TI) clear corneal incisions on corneal higher order aberrations (HOAs) in patients undergoing cataract surgery with healthy corneas and mild astigmatism.
- 102 eyes were analyzed, with measurements taken before and 6 weeks after surgery, revealing significant changes in HOAs only in the SI group, particularly vertical and horizontal coma.
- The findings suggest that while SI can alter corneal HOAs and potentially impact vision quality post-surgery, TI may offer advantages by not producing significant changes.
Aims/background: Fear of childbirth (FoC) and its extreme form, tokophobia, is a clinical condition that can lead to many negative consequences, and its importance is increasingly understood. This article aims to assess the severity of FoC and anxiety levels according to different attachment styles and to investigate the relationships between these factors.
Design/methods: A cross-sectional study was conducted in a state hospital in the largest city in Turkey.
Article Synopsis
- A study was conducted to evaluate the Eyecryl toric phakic IOL (pIOL) for patients with moderate-to-high myopic astigmatism, focusing on visual and refractive outcomes over three years.
- The research included 52 eyes from 28 patients, showing a significant improvement in visual acuity and reduction in astigmatism, with 70% of eyes achieving better vision versus preoperative levels.
- The findings indicate that the Eyecryl toric pIOL is effective and safe, though some patients experienced minor complications, such as cell loss and opacification issues.
Purpose: To compare the complications and postoperative outcomes of Nd:YAG laser anterior capsulotomy vs a needle aspiration approach for capsulorhexis in patients with intumescent cataracts.
Setting: University of Health Sciences, Basaksehir Cam and Sakura City Hospital Department of Ophthalmology, Istanbul, Turkey.
Design: Retrospective, cross-sectional study.
Objectives: The objective of this study was to analyze the changes in the effective optical zones (EOZ) using topographic techniques on the tangential curvature difference map at post-operative 1-year following transepithelial photorefractive keratectomy (T-PRK) and to identify parameters linked to the EOZ alterations.
Methods: The study comprised 55 eyes of 55 myopic patients who underwent T-PRK. EOZs were measured using the tangential curvature difference map of the Scheimpflug tomography system.
Objective: The purpose of the study was to analyse the role of prognostic factors on the risk of recurrence and overall survival of patients with uterine adenosarcoma.
Methods: A retrospective international multicentre study involving 46 centres collected 32 cases of uterine adenosarcoma, and these cases were included in the present subanalysis. Clinical and demographic features and tumour characteristics were gathered, as well as information on treatment and relapse.
Purpose: To compare the effective optical zones (EOZs) of small-incision lenticule extraction (SMILE) and femtosecond laser-assisted in situ keratomileusis (F-LASIK) by utilizing topographic methods on the tangential curvature difference map at postoperative 1 year and to identify parameters linked to the EOZ alterations following both surgeries.
Methods: Myopic patients who underwent SMILE or F-LASIK were included in the study. Patients with refractive error greater than -9.
Background: Fuchs uveitis syndrome (FUS) is a chronic intraocular inflammatory disease. It can lead to glaucoma which can be intractable to both medical and surgical treatment. In the present report, we describe our experience with GATT as a primary surgical option in the treatment of glaucoma secondary to FUS.

Methods: The study included consecutive patients diagnosed with ocular rosacea, referred to a tertiary hospital between 2021 and 2023. Each patient underwent biomicroscopic examinations, non-invasive TBUT assessments, corneal fluorescein staining (evaluated using the Oxford scoring system), and meibography.
Purpose: To evaluate the long-term clinical outcomes, safety and efficacy of Eyecryl posterior-chamber phakic intraocular lens implantation (pIOL) implantation in patients with high myopia.
Methods: Patients with myopia between -6.00 and -20.
Evaluation of the association COMT Val158Met variant and childhood trauma on aggression in Turkish SCZ patients.
Nucleosides Nucleotides Nucleic Acids
December 2024
Childhood trauma is a serious form of stress that makes individuals more vulnerable to developing Schizophrenia (SCZ). Many studies have predicted the association between the catechol-O-methyltransferase (COMT) gene Val158Met variant and aggressive attack. We aimed to investigate the association the COMT variant and childhood trauma on aggression in Turkish SCZ patientsThis study included 89 patients diagnosed with SCZ.

In the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), SAD diagnostic criteria were changed, and instead of a cross-sectional diagnosis, a longitudinal approach covering the life course of the illness was adopted. In this study, the meaning of this conceptual shift in the diagnosis of SAD in clinical practice is investigated throughout the course of the illness for patients with SAD.

Methods: A sub-analysis of the SARComa of the UTerus (SARCUT) study, which is a multicentric cross-sectional pan-European study that included 390 patients diagnosed with leiomyosarcoma, between 2001 and 2007. Perioperative factors related to risk of recurrence and survival were analyzed.
Background: High-complexity and low-prevalence procedures benefit from treatment by referral centers. The volume of cases necessary to maintain high training in the treatment of gynecologic sarcoma is currently unknown. This study aimed to determine differences in survival and recurrence as a function of the volume of patients treated per center.

- Prolonged grief disorder (PGD) has become more recognized, especially after the Covid-19 pandemic, with a study showing a 44.1% prevalence among outpatient psychiatric patients who lost a first-degree relative in the last 12-24 months.
- The study found no differences in PGD rates based on whether the death was due to Covid-19 or other causes; however, it was linked to factors like the bereaved person's age, age of the deceased, and relationship closeness.
- Patients with PGD exhibited higher levels of depression, insomnia, and anxious attachment, with unexpected deaths being a significant predictor of developing PGD, highlighting the need for clinicians to be vigilant in monitoring and treating this disorder.
Purpose: Investigation of the relationship between blepharitis-related symptom scores, tear film functions, and conjunctival microbiota in patients with ocular rosacea (OR) compared with healthy controls was aimed.
Methods: Consecutive 33 eyes of 33 patients with OR who were admitted from the dermatology clinic and age-matched and gender-matched 30 healthy controls were included in the study. Tear breakup time (TBUT), Schirmer score, and blepharitis symptom score (BLISS) were recorded for each patient.
Introduction: Clozapine may affect the outcome of severe COVID-19 infection due to its anti-inflammatory and immunosuppressant effects. This study aimed to investigate whether the risk of COVID-19 changed in schizophrenic patients using clozapine and to compare patients using clozapine with other antipsychotics in terms of COVID-19 severity.
Methods: A total of 732 patients who were registered and followed up with a diagnosis of schizophrenia were included in the study.

Methods: An international multicenter study involving 43 international centers, the SARCUT study, collected 966 uterine sarcoma cases; among them 39 cases corresponded to undifferentiated uterine sarcoma and where included in the present subanalysis. The risk factors related to the oncological outcomes where analyzed.
Objective: Uterine sarcomas are a rare and heterogeneous group of malignancies that include different histological sub-types. The aim of this study was to identify and evaluate the impact of the different prognostic factors on overall survival and disease-free survival of patients with uterine sarcoma.
Methods: This international multicenter retrospective study included 683 patients diagnosed with uterine sarcoma at 46 different institutions between January 2001 and December 2007.
