ABSTRACT OBJECTIVE: The main objective of this study was to review the clinicopathologic characteristics and outcome of patients with oncocytic papillary thyroid carcinoma (PTC) and oncocytic poorly differentiated thyroid carcinoma (PDTC). The secondary objective was to evaluate the prevalence and outcomes of RAI use in this population. METHODS: Patients with oncocytic PTC an d PDTC who were treated at a quaternary cancer centre between 2002 and 2017 were retrospectively identified from an institutional database. All patients had an expert pathology review to ensure consistent reporting and definition. The cumulative incidence function was used to analyse locoregional failure (LRF) and distant metastasis (DM) rates. Univariable analysis (UVA) was used to assess clinical predictors of outcome. RESULTS: In total, 263 patients were included (PTC [n=218], PDTC [n=45]) with a median follow up of 4.4 years (range: 0 = 26.7 years). Patients with oncocytic PTC had a 5/10-year incidence of LRF and DM, respectively, of 2.7%/5.6% and 3.4%/4.5%. On UVA, there was an increased risk of DM in PTC tumors with widely invasive growth (HR 17.1; p<0.001), extra-thyroidal extension (HR 24.95; p<0.001), angioinvasion (HR 32.58; p=0.002), focal dedifferentiation (HR 19.57, p<0.001), and focal hobnail cell change (HR 8.67, p=0.042). There was additionally an incr eased risk of DM seen in male PTC patients (HR 5.5, p=0.03).The use of RAI was more common in patients with larger tumors, angioinvasion, and widely invasive disease. RAI was also used in the management of DM and 43% of patients with oncocytic PTC had RAI-avid metastatic disease. Patients with oncocytic PDTC had a higher rate of 5/10-year incidence of LRF and DM (21.4%/45.4%; 11.4%/40.4%, respectively). Patients with extra-thyroidal extension had an increased risk of DM (HR 5.52, p=0.023) as did those with angioinvasion. Of the patients with oncocytic PDTC who received RAI for the treatment of DM, 40% had RAI-avid disease. CONCLUSION: We present a large homogenous cohort of patients with oncocytic PTC and PDTC, with consistent pathologic reporting and definition. Patients with oncocytic PTC have excellent clinical outcomes and similar risk factors for recurrence as their non-oncocytic counterparts (angioinvasion, large tumor size, extra-thyroidal extension, and focal dediffere ntiation). Compared with oncocytic PTCs, the adverse biology of oncocytic PDTCs is supported with increased frequency of DM and lower uptake of RAI.

Effect of patella resurfacing on functional outcome and revision rate in primary total knee arthroplasty (Review)

xlomafota13 shared this article with you from Inoreader Effect of patella resurfacing on functional outcome and revision rate in primary total knee arthroplasty (Review) Via Experimental and therapeutic medicine Exp Ther Med. 2022 Jan;23(1):104. doi: 10.3892/etm.2021.11027. Epub 2021 Dec 1. ABSTRACT Anterior knee pain, as well as patellofemoral disorders, after total knee arthroplasty are important reasons for revision in total knee arthroplasty. Current prosthesis designs include patellar components for patella replacement, and together with improved rational design of the prosthesis and advancement in knee alignment these appear to reduce the incidence of anterior knee pain following total knee replacement, even if the etiology of anterior knee pain remains unclear. However, new complications related to patella resurfacing emerge with this approach. At present, there are three strategies involving patella replacement in total knee arthroplasty: There are surgeons who always replace the patella, others who never resurface the patella and a third group of surgeons who usually do not resurface the patella but replace the patella in particular s ituations. There are arguments to support each of these viewpoints regarding patella resurfacing but no strong arguments to favor any of them. Finally, the decision to resurface the patella or not should be based on the practice, training and experience of individual surgeons. The aim of this review was to analyze the results of different strategies for patella resurfacing in terms of functional outcome and revision rate following primary total knee arthroplasty.

Suicidality and COVID-19: Suicidal ideation, suicidal behaviors and completed suicides amidst the COVID-19 pandemic (Review)

xlomafota13 shared this article with you from Inoreader Suicidality and COVID-19: Suicidal ideation, suicidal behaviors and completed suicides amidst the COVID-19 pandemic (Review) Via Experimental and therapeutic medicine Exp Ther Med. 2022 Jan;23(1):107. doi: 10.3892/etm.2021.11030. Epub 2021 Dec 2. ABSTRACT Since the outbreak of the coronavirus 2019 (COVID-19) pandemic, there has been widespread concern that social isolation, financial stress, depression, limited or variable access to health care services and other pandemic-related stressors may contribute to an increase in suicidal behaviors. In patients who have recovered from COVID-19, an increased risk of developing suicidal behaviors may be noted, while post-COVID syndrome comprises another potential risk factor contributing to increased suicidal behaviors. Despite the initial alarming predictions for an increase in suicide rates due to the COVID-19 pandemic, the majority of published studies to date suggest that experienced difficulties and distress do not inevitably translate into an increased number of suicide-related deaths, at least not in the short-term. Nevertheless, the long-term mental h ealth effects of the COVID-19 pandemic have yet to be unfolded and are likely to remain for a long period of time. Suicide prevention and measures aiming at promoting well-being and mitigating the effects of COVID-19 on mental health, particularly among vulnerable groups, should thus be a priority for healthcare professionals and policymakers amidst the evolving COVID-19 pandemic.

Online ahead of print. ABSTRACT Significance statement: A 53-year-old man with left facial pain was referred to our hospital. Nasal endoscopy revealed a purulent discharge at the left middle meatus and bulging of the uncinate process. Computed tomography demonstrated that the dental implant was blocking the left maxillary ostium. Functional endoscopic sinus surgery was performed under gene ral anesthesia. After removal of the uncinate process, a yellowish purulent discharge in the left maxillary sinus discharged from the maxillary sinus. The presence of the dental implant in the infundibulum shows the direction of mucociliary clearance from the nasal sinus. This case indicates how our sinus clears a foreign body, and the direction in which the foreign body is removed. PMID:34978203 | DOI:10.1177/01455613211062454 View on the web Inoreader.

Environmental enrichment preserves hippocampal neurons in diabetes and stressed rats

xlomafota13 shared this article with you from Inoreader Environmental enrichment preserves hippocampal neurons in diabetes and stressed rats Via Cellular and Molecular Biology Histol Histopathol. 2022 Jan 3:18418. doi: 10.14670/HH-18-418. Online ahead of print. ABSTRACT This study evaluated the effect of Environmental Enrichment (EE) on neuron morphology in the CA1, CA3 and dentate hilus (DH) regions of the hippocampus by quantitating the total dendritic arborizations. EE is a potential intervention for stress and diabetes. It is capable of mitigating diabetes and stress-induced cognitive and memory deficit. Diabetes and stress were induced in male Wistar rats (4-5 weeks). Diabetic and stressed rats were exposed to EE on Day 2 post STZ injection and subsequently once daily for 30 days. All animals were sacrificed on Day 30. The hippocampus was dissected and processed for Golgi staining to quantitate dendritic arborizations at the CA1, CA2 and DH regions. Diabetes (D) and Diabetes+stress (D+S) groups had significantly fewer apical and basal dendritic branching points (ADBP, BDBP) at CA1 (p<0.01), CA3 (p< ;0.001) and DH (p<0.001) relative to control group (NC). Diabetes and stressed rats exposed to EE: [D+EE and D+S+EE groups] exhibited significantly denser ADBP and BDBP at all regions relative to D (p<0.001) and (D+S+EE) (p<0.001) groups respectively. EE significantly preserved neuronal arborizations in hippocampus of diabetic and stressed rats, suggesting a potential entity of diabetes and stress management.

xlomafota13 shared this article with you from Inoreader Open partial horizontal laryngectomy for T2-T3-T4a laryngeal cancer: oncological outcomes and prognostic factors of two Italian hospitals Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2022 Jan 3. doi: 10.1007/s00405-021-07238-x. Online ahead of print. ABSTRACT PURPOSE: The purpose of this study was to analyse the oncologic results of open partial horizontal laryngectomy (OPHL) and to assess the prognostic factors that could affect the survival of patients affected by T2, T3 and T4a laryngeal cancer. Using this data, we aim to identify clinical criteria to select patients amenable to conservative surgery, and to facilitate a more targeted approach in the management of advanced laryngeal cancer. METHODS: A retrospective study was performed in patients who underwent OPHL type II for laryngeal squamous cell carcinoma from January 2005 to December 2018. We analysed a total of 170 patients; 21(12.36%) cases were staged as pT2, 116 (68.23%) as pT3 and 33 (19.41%) as pT4a. RESULTS: Five-year overall survival (OS) was 80.9%, 79.3%, 70.4% for T2, T3 and T4 respectively. Disease-specific survival (DSS) was 90.4%, 85.3% and 77.4%. Posterior tumour extension, perineural invasion and N status showed to considerably influence survival in both uni- and multivariate analyses. CONCLUSION: The oncological outcomes from our study show that OPHL for advanced laryngeal cancer can guarantee a high percentage of success. Accurate patient selection is of utmost importance to differentiate advanced disease amenable to conservative surgery, and treatment options should consider selected criteria based on tumour and patient features.

Advantages of Pulse Rate Compared to Modulation Frequency for Temporal Pitch Perception in Cochlear Implant Users

xlomafota13 shared this article with you from Inoreader Advantages of Pulse Rate Compared to Modulation Frequency for Temporal Pitch Perception in Cochlear Implant Users Via Journal of the Association for Research in Otolaryngology Abstract Most cochlear implants encode the fundamental frequency of periodic sounds by amplitude modulation of constant-rate pulsatile stimulation. Pitch perception provided by such stimulation strategies is markedly poor. Two experiments are reported here that consider potential advantages of pulse rate compared to modulation frequency for providing stimulation timing cues for pitch. The first experiment examines beat frequency distortion that occurs when modulating constant-rate pulsatile stimulation. This distortion has been reported on previously, but the results presented here indicate that distortion occurs for higher stimulation rates than previously reported. The second experiment examines pitch resolution as provided by pulse rate compared to modulation frequency. The results indicate that pitch discrimination is better with pulse rate than with modulation frequency. The advantage was large for rates near what has been suggested as the upper limit of temporal pit ch perception conveyed by cochlear implants. The results are relevant to sound processing design for cochlear implants particularly for algorithms that encode fundamental frequency into deep envelope modulations or into precisely timed pulsatile stimulation.

Sorafenib induces pigmentation via the regulation of β‐catenin signalling pathway in melanoma cells

xlomafota13 shared this article with you from Inoreader Sorafenib induces pigmentation via the regulation of β‐catenin signalling pathway in melanoma cells Via Experimental Dermatology Abstract We conducted large-scale screening test on drugs that were already approved for other diseases to find pigmentation-modulating agents. Among drugs with potential for pigmentation control, we selected sorafenib and further investigated the effect on pigmentation using HM3KO melanoma cells. As a result of treating melanoma cells with sorafenib, pigmentation was promoted in terms of melanin content and tyrosinase activity. Sorafenib increased mRNA and protein levels of pigmentation-related genes such as MITF, tyrosinase and TRP1. To uncover the action mechanism, we investigated the effect of sorafenib on the intracellular signalling pathways. Sorafenib reduced phosphorylation of AKT and ERK, suggesting that sorafenib induces pigmentation through inhibition of the AKT and ERK pathways. In addition, sorafenib significantly increased the level of active β-catenin, together with activation of β-catenin signalling. Mechanistic study revealed that sorafenib decreased phosphorylation of s erine 9 (S9) of GSK3β, while it increased phosphorylation of tyrosine 216 (Y216) of GSK3β. These results suggest that sorafenib activates the β-catenin signalling through the regulation of GSK3β phosphorylation, thereby affecting the pigmentation process. View on the web Inoreader.

Biomarkers in melanoma and non‐melanoma skin cancer prevention and risk stratification

xlomafota13 shared this article with you from Inoreader Biomarkers in melanoma and non‐melanoma skin cancer prevention and risk stratification Via Experimental Dermatology Abstract The rates of melanoma and non-melanoma skin cancer (NMSC) have been increasing over the last twenty years in the United States, and this has been attributed to increased ultraviolet radiation exposure (UVR). Given these rising rates, preventative measures have become increasingly important to reduce the incidence and promote early detection of these cancers. Skin cancer prevention remains a challenging task to accomplish mainly due to the lack of reliable and sensitive methods to provide objective risk information that can educate and motivate individuals to avoid sunburn. Currently, minimal erythema dose (MED) is used as a marker of UVR. However, it is not an ideal marker because significant cancer-related molecular damage can occur after UVR exposure that cannot be detected by MED. Thus, over the recent years there has been significant interest in development of biomarkers indicative of exposure to UVR to improve early detection of cutaneous malignancies. Here, we will discuss e merging biomarkers for melanoma and NMSC that can help with risk stratification and targeted prevention and treatment. View on the web Inoreader.
