RESUMO
RESUMEN: El objetivo del presente estudio fue describir los cambios clínicos e imagenológicos de las terapias no invasivas aplicadas a pacientes con alteraciones óseas degenerativas de las articulaciones temporomandibulares (ATM). Metodología: Se evaluaron 25 pacientes con alteraciones óseas degenerativas de las ATM, sin tratamiento previo de trastornos temporomandibulares (TTM) al momento del diagnóstico. Se realizó tratamiento no invasivo y un año después fueron evaluados según criterios clínicos e imagenológicos DC/TMD y Ahmad. Los resultados fueron presentados por medio de estadística descriptiva, odds ratio con sus respectivos intervalos de confianza, comparaciones de medianas y correlaciones. Se estudiaron 50 ATM, 72 % mujeres (32,2 años promedio). Se observó mejora significativa en los parámetros: dolor (p=0,0001), sinovitis (p=0,001) e incremento de la esclerosis del trabeculado óseo (p=0,051) a un año post-tratamiento. Después de un año del establecimiento de terapias no invasivas en pacientes con alteraciones óseas degenerativas de las ATM, se observaron cambios positivos tanto clínicos como imagenológicos, reduciéndose significativamente la sintomatología dolorosa, limitándose la progresión del daño óseo degenerativo, y observándose recuperación de los casos de sinovitis.
ABSTRACT: The objective of this study was to describe clinical and imaging changes of non-invasive therapies applied to patients with degenerative bone disorders of the temporomandibular joints (TMJ). To carry out this study, 25 patients with degenerative bone disorders of TMJ without previous treatment at the time of diagnosis, were evaluated. Non-invasive treatment was performed and one year later they were evaluated according to clinical and imaging criteria DC/TMD and Ahmad. Results were presented by descriptive statistics, odds ratio, confidence interval, comparisons of means, and correlations. 50 TMJs, 72 % women, (32.2 years mean of age) were studied. Significant improvement was observed in the parameters: pain (p=0.0001), synovitis (p=0.001), and increased sclerosis of the bone trabeculae (p=0,051) at one-year post-treatment. After one year of the establishment of non-invasive therapies in patients with degenerative joint disease of TMJ, it was observed positive changes, both clinical and imaging, reducing painful symptomatology, limiting effect on the progression of degenerative bone damage, and recovery of synovitis cases.
RESUMO
A major hallmark of cancer is successful evasion of regulated forms of cell death. Ferroptosis is a recently discovered type of regulated necrosis which, unlike apoptosis or necroptosis, is independent of caspase activity and receptor-interacting protein 1 (RIPK1) kinase activity. Instead, ferroptotic cells die following iron-dependent lipid peroxidation, a process which is antagonised by glutathione peroxidase 4 (GPX4) and ferroptosis suppressor protein 1 (FSP1). Importantly, tumour cells escaping other forms of cell death have been suggested to maintain or acquire sensitivity to ferroptosis. Therefore, therapeutic exploitation of ferroptosis in cancer has received increasing attention. Here, we systematically review current literature on ferroptosis signalling, cross-signalling to cellular metabolism in cancer and a potential role for ferroptosis in tumour suppression and tumour immunology. By summarising current findings on cell biology relevant to ferroptosis in cancer, we aim to point out new conceptual avenues for utilising ferroptosis in systemic treatment approaches for cancer.
