RESUMEN
Objective: This study aims to elucidate the comprehensive effects of metabolic syndrome (MetS) on the structural integrity of subcortical brain regions and associated structures through high-resolution magnetic resonance imaging (MRI) volumetric analysis, thereby contributing to a deeper understanding of the neuroanatomical dimensions of MetS and its potential implications for cognitive functions and overall brain health. Methods: A cross-sectional design was implemented, involving 25 individuals diagnosed with MetS for at least one year and a healthy control group of 15 individuals at a tertiary hospital's family medicine clinic in Eastern Turkey. Participants underwent a high-resolution MRI scan using a 1.5T Siemens Aera scanner. The MRICloud platform was employed for comprehensive segmentation and quantitative analysis of various brain structures. Results: The study revealed significant volumetric reductions in all measured subcortical brain regions among individuals with MetS compared to the control group (all P < 0.05). Notable differences were observed in key structures such as the substantia nigra, corpus callosum, and thalamus. In subcortical structures, the largest volumetric differences were noted in the basal ganglia L (1322.4 mm³), while the most significant percentage differences were seen in the substantia nigra R (25.24%) and caudate nucleus L (21.02%). Conclusion: The findings from this study underscore the significant neuroanatomical changes associated with MetS, manifesting as volumetric reductions in critical subcortical brain areas. These alterations underscore the necessity for further research into the comprehensive influence of MetS on cognitive processes and the potential for early therapeutic interventions.
RESUMEN
Autophagy and DNA repair are two essential biological mechanisms that maintain cellular homeostasis. Impairment of these mechanisms was associated with several pathologies such as premature aging, neurodegenerative diseases, and cancer. Intrinsic or extrinsic stress stimuli (e.g., reactive oxygen species or ionizing radiation) cause DNA damage. As a biological stress response, autophagy is activated following insults that threaten DNA integrity. Hence, in collaboration with DNA damage repair and response mechanisms, autophagy contributes to the maintenance of genomic stability and integrity. Yet, connections and interactions between these two systems are not fully understood. In this review article, current status of the associations and crosstalk between autophagy and DNA repair systems is documented and discussed.
RESUMEN
OBJECTIVE: This study aimed to investigate the mediating role of social support in the relationship between resilience and quality of life (QoL) among Turkish patients with early-stage breast cancer. METHODS: The study used a descriptive and cross-sectional design and was carried out in the oncology ward of a hospital in the Central Anatolia region of Turkey. A demographic-disease survey, the Turkish version of the Connor-Davidson Resilience Scale 25, the Multidimensional Perceived Social Support Scale, the European Organization for Research and Treatment of Cancer QoL Questionnaire Core, and the QoL Questionnaire Breast Cancer 23 were used to interview 113 patients with breast cancer. RESULTS: Social support played a partial mediator role in the relationship between resilience and functional QoL. There was a negative correlation between functional QoL Questionnaire Breast Cancer 23 and psychological resilience and social support (P < 0.005). The mediation effect ratio was 10.2% (R 2 = 0.102). Social support was found to not have a mediating role in the relationship between psychological resilience and general QoL (P < 0.05). CONCLUSIONS: Patients do not want social support to end, and their weakness in the eyes of others may have a negative impact on their QoL and resilience.
RESUMEN
Psychological resilience is considered to be promising especially for patients with CRC, which is among the most frequent types of cancer and is known to have serious physical and psycho-social impacts on individuals. Thus, it is stated that psychosocial interventions need to be done in order to overcome emotional stress. This study was conducted to determine the correlation between social support and resilience in patients undergoing surgical therapy due to colorectal cancer. The study is descriptive and cross sectional. A patient information form, Connor-Davidson Resilience Scale, and Multidimensional Scale of Perceived Social Support were used to interview 103 patients undergoing colorectal cancer surgery. It was determined that family support and significant other support were positively correlated with subscale and total scores of the Resilience Scale (p < 0.05). It was determined that the model was highly significant (R2 = 0.113; p < 0001). An increase of 1 unit in healthcare professionals support triggered an increase of one-unit (0.976) in psychological resilience (p:0.014). It was determined that social support provided to patients, undergoing surgical therapy due to colorectal cancer, by family and healthcare professionals, played an essential role in increasing resilience.
