Background/aim: Subarachnoid haemorrhage (SAH) is a severe cerebrovascular condition with high morbidity and mortality. Inflammation and oxidative stress are key factors in its pathophysiology, particularly in secondary vascular injury. This study aimed to evaluate the effects of colchicine on vascular integrity and biochemical markers following SAH in an experimental rat model.
Materials and methods: Eighteen female Sprague-Dawley rats were divided into three groups: Control (no SAH), SAH (induced without treatment), and SAH + Colchicine (1 mg/kg intraperitoneally at 1 h and 24 h). SAH was induced by autologous blood injection into …

The Lived Experiences Of Intimacy And Isolation In Single Mothers During Covid-19: An Eriksonian Perspective, Chante Renee Reeves
Walden Dissertations and Doctoral Studies
Single mothers were largely absent from the COVID-19 literature, despite being head of household in approximately 80% of single-parent homes. The purpose of this phenomenological qualitative research study was to gain insight into the lived experiences of single mothers during the COVID-19 pandemic. This study addressed how this group connected with family, friends, and others in meaningful ways despite government-imposed lockdowns and restrictions. This phenomenon was explored through Erik Erikson’s psychosocial development theory, with a focus on the intimacy versus isolation stage. An Eriksonian perspective on relationship building and maintenance in adulthood can help better understand and address the social …

Walden Dissertations and Doctoral Studies
According to the American Counseling Association (ACA, 2014) Code of Ethics, professional counselors are responsible to monitor their own impairment. Specific interventions to prevent impairment and foster counselor professional well-being (PWB) and resiliency are imperative in a profession in which it is ethically required to continuously provide competent counseling. The purpose of this study was to explore the narratives of licensed counselors’ PWB during the onset of and successively during the coronavirus disease 2019 (COVID-19) pandemic. The theoretical orientation for this study was Dewey’s theory of experience. Nine counselor participants who were licensed by May 2018 shared detailed accounts of …

Turkish Journal of Medical Sciences
Background/aim: Cryptorchidism is the most common congenital anomaly of the male genitourinary system, characterized by a multifactorial etiology. The disheveled-associated activator of morphogenesis 2 (DAAM2) gene regulates androgen receptor (AR)- dependent transcription; its variants are associated with partial androgen insensitivity. Since the inguinoscrotal phase of testicular descent is androgen-dependent, we hypothesized that DAAM2 variants contribute to cryptorchidism susceptibility. This pilot study, designed to generate hypotheses rather than to establish association, investigated the frequency of two functionally characterized DAAM2 variants, p.(Asp165Glu) and p.(Asn614ThrfsTer2), in pediatric cryptorchidism.
Materials and methods: This prospective case-control study included 40 male pediatric cryptorchidism patients and 39 …

Background/aim: In modern healthcare, patient education materials (PEMs) are essential for bridging the gap between clinical knowledge and patient understanding. However, in Türkiye, where 64.6% of the adult population possesses inadequate or problematic health literacy, traditional medical brochures often exceed recommended reading levels. This study aimed to evaluate and compare the readability of Turkish dermatology PEMs prepared by the Turkish Dermatology Association (TDA) with those generated by artificial intelligence (AI) models.
Materials and methods: A total of 68 TDA PEMs were analyzed. Readability was assessed using the Ateşman Readability Index. Responses were generated by AI models to questions extracted from …
