After radical prostatectomy, men with adverse pathologic features or a persistent postoperative detectable prostate-specific antigen (PSA) are candidates for postoperative radiation therapy (PORT). Previous data have suggested disparities in receipt of adjuvant radiation therapy for adverse pathologic features according to travel distance. Among patients without adverse pathologic features (pT2 disease and negative margins), the main indication for PORT is a persistent postoperative detectable PSA. However, it remains unknown whether the rate of receipt of PORT in this cohort of men with persistently detectable PSA is related to travel distance from the treating facility.

Using the National Cancer Database, we identified 170,379 men with prostate cancer diagnosed from 2004 to 2015 managed with upfront surgery who were found to have pT2 disease with negative surgical margins. Multivariable logistic regression defined adjusted odds ratios (AORs) with 95% confidence intervals (CIs) of receiving PORT as the p PORT for patients with persistent postoperative detectable PSA.
For men with localized prostate cancer without adverse pathologic features managed with surgery, increasing distance from treatment facility was associated with lower receipt of PORT. Given that the rate of a persistent postoperative detectable PSA is unlikely to depend on the distance to the treatment facility, these findings raise the possibility that the geographic availability of radiation treatment facilities influences the decision to undergo PORT for patients with persistent postoperative detectable PSA.
Biogenesis and function of mitochondria is profoundly dependent on cytosolic translation of mitochondrial pre-proteins and its subsequent translocation and folding inside the organelle. Continuous exposure of non-native precursor proteins, exposure to damaging by-products of oxidative phosphorylation, load of mis-targeted or misfolded proteins from neighbouring compartments and unremitting demand of communication between mitochondrial and nuclear genomes, continuously pose proteotoxic threats to the organelle. Our knowledge of cellular mechanisms to cope up with such impending threat of proteotoxicity to mitochondria, is currently evolving. In recent years, several unique response and survival pathways have been discovered shedding light on cellular strategies to cope with stressed and dysfunctional mitochondria. As mitochondria compulsorily communicate with nucleus, cytosol and endoplasmic reticulum (ER) for its own biogenesis and function and in turn maintain critical cellular processes for survival, any rategies to counter such stress to overcome dysfunctions of the organelle. Mitochondrial communication with neighbouring subcellular compartments like ER and cytosol during proteotoxic stress have been explored. In the context of mitochondrial proteotoxicity, alterations of crucial inter-organelle connections like ER-mitochondria contact sites and its implication on mitochondrial signaling activity like Ca2+ signaling have been dissected. selleck compound Furthermore, an overview of pathological conditions, mainly neurodegenerative disorders that are known to be associated with mitochondrial proteotoxicity and Ca2+ dysregulation has been presented.The classical necroptosis signaling is mediated by death receptors (DRs) that work in synergy with traditional caspase inhibitory signals. Currently, potential therapeutic molecules are in various phases of clinical trials for a spectrum of pathological conditions associated with necroptosis. However, a non-classical model of necroptosis has also emerged over the last decade with a relatively unexplored molecular mechanism. Although in vitro studies and preclinical models have shown its close association with mitochondrial dysfunction (mito-dysfunction), contradictory reports have emerged which complicate its definitiveness. Though impaired mitochondrial calcium ([Ca2+]m) handling is established in necrotic cell death, how this interplay regulates necroptosis is yet to be elucidated. Taking these questions into consideration, we have discussed various molecular aspects of necroptosis with the emerging role of mito-dysfunction. Based on the central role of altered [Ca2+]m handling in mito-dysfunction mediated necroptosis, we have provided a comprehensive molecular insight into this emerging paradigm. Potential reasons for the contradictory findings regarding the role of mito-dysfunction in necroptosis in general and mitochondrial-dependent necroptosis in specific are discussed. We also provide insights into the current understanding of how [Ca2+]m can be a critical determinant in deciding the cell fate under certain pathological conditions, while under others it may be dispensable. Lastly, we have highlighted the key molecular targets which have a direct implication for therapeutic intervention in conditions that are associated with impaired [Ca2+]m handling and cell death by necroptosis.The understanding of the pathophysiology of bipolar disorder (BD) remains modest, despite recent advances in neurobiological research. The mitochondrial dysfunction hypothesis of bipolar disorder has been corroborated by several studies involving postmortem brain analysis, neuroimaging, and specific biomarkers in both rodent models and humans. Evidence suggests that BD might be related to abnormal mitochondrial morphology and dynamics, neuroimmune dysfunction, and atypical mitochondrial metabolism and oxidative stress pathways. Mitochondrial dysfunction in mood disorders is also associated with abnormal Ca2+ levels, glutamate excitotoxicity, an imbalance between pro- and antiapoptotic proteins towards apoptosis, abnormal gene expression of electron transport chain complexes, and decreased ATP synthesis. This paper aims to review and discuss the implications of mitochondrial dysfunction in BD etiology and to explore mitochondria as a potential target for novel therapeutic agents.
Tibial avulsion fracture of the posterior cruciate ligament is not rare in the clinic. Arthroscopic treatment is increasingly accepted, but the choice of fixation has been debated. This study aims to compare the clinical outcomes of suture and EndoButton fixation under arthroscopy for acute displaced posterior cruciate ligament avulsion fractures.

A total 68 of 83 PCL tibial avulsion fracture cases from 2009 to 2016 were retrospectively reviewed. Some patients received arthroscopic suture initially, and later the others received arthroscopic EndoButton fixation. Associated lesions were treated if present. The Lysholm and International Knee Documentation Committee (IKDC) scores, KT-1000 arthrometry and plain radiography were evaluated at follow-up. The assessment data at two years of follow-up were used for comparing the two different fixation groups.

The follow-up time of 63 patients was more than 2 years. In total, 32 of the 63 patients were in the suture group, and 31 were in the EndoButton group. At two years of follow-up, knee function according to the Lysholm score was a mean of 92.
