Online ahead of print. ABSTRACT PURPOSE: This study aimed to evaluate late and asymptomatic patients after open partial horizontal laryngectomy (OPHL), investigating the clinical-surgical and socio-demographic factors associated with aspiration and severe dysphagia. METHODS: One-thousand videofluoroscopic swallowing studies were performed in 100 asymptomatic patients in the late period after OPHL(median 6.5 years). Aspiration and severe dysphagia were, respectively, assessed by the Penetration-Aspiration scale (PAS) and by the Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) classification. Associated factors were investigated by multivariate logistic regressions. RESULTS: 34% (95% CI 24.3-47.6%) of patients presented aspiration and 23% (95% CI 15.3-34.6%) had severe or life-threatening dysphagia (DIGEST grades 3-4). On logistic regression, the pre sence of aspiration was associated with lower preoperative serum albumin (odds ratio [OR]: 0.22; 95% CI 0.07-0.64; p = 0.005, for each 1 g/dL increment); a greater weight loss in early postoperative period (OR: 1.19, 95% CI 1.05-1.35; p = 0.008, for each 1 kg loss); older age at surgery (OR: 1.08; 95% CI 1.01-1.17, for each 1-year older); and with the presence of diabetes (OR: 5.16; 95% CI 1.09-27.47; p = 0.039). CONCLUSION: Deglutition abnormalities are frequent in asymptomatic patients later after OPHL. Older patients, with lower preoperative serum albumin levels, with greater postoperative weight loss, and with diabetes compose the clinical profile at risk for having worse swallowing function in the late period after OPHL.

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.

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.

Administrative delays of temporary recommendation for use: Impact on access to innovation in melanoma

xlomafota13 shared this article with you from Inoreader Administrative delays of temporary recommendation for use: Impact on access to innovation in melanoma Via Association française pour l'étude du cancer Bull Cancer. 2021 Dec 28:S0007-4551(21)00514-2. doi: 10.1016/j.bulcan.2021.11.007. Online ahead of print. ABSTRACT INTRODUCTION: Melanoma has benefited in recent years from therapeutic innovations, which have improved overall survival of patients. France has developed a regulatory arsenal allowing faster access to innovative drugs before marketing authorization: temporary authorization for use (ATU) and temporary recommendation for use (RTU). METHOD: We describe here the decision-making processes that led to the non-publication of the decree on the funding of three RTU in adjuvant melanoma therapy: nivolumab, pembrolizumab and the combination of dabrafenib and trametinib, and we analyse the fate of these drugs in order to quantify the potential loss of chance. RESULTS: On 03AUG2018, the French National Agency for Medicines and Health Product Safety (ANSM) published 3 RTU in order to give rapid access to major innovations in adjuvant melanoma therapy: nivolumab, pembrolizumab and the combination of dabrafenib and trametinib. These drugs have respectively demonstrated reductions in the risk of recurrence by 35 %, 43% and 55% for target populations of 2200, 1900 and 650 patients per year. Despite a favourable opinion on reimbursement from the French National Authority for Health (HAS), the decrees on reimbursement will never be published, prohibiting the use of these products before the marketing authorisation, and depriving many patients of a potential cure. CONCLUSION: Despite a favourable opinion from scientists and health agencies for the rapid availability of a drug, the French public health code does not systematically imply access to a therapeutic innovation. The reform of access to innovation implemented on 01JUL2021 may help tackle this issue. PMID:34972538 | DOI:10.1016/j.bulcan.2021.11.007 View on the web Inoreader.

Establishment and Characterization of FusionRed Stable Transfected Canine Prostate Adenocarcinoma and Transitional Cell Carcinoma Cells

xlomafota13 shared this article with you from Inoreader Establishment and Characterization of FusionRed Stable Transfected Canine Prostate Adenocarcinoma and Transitional Cell Carcinoma Cells Via In vivo (Athens, Greece) In Vivo. 2022 Jan-Feb;36(1):170-179. doi: 10.21873/invivo.12688. ABSTRACT BACKGROUND/AIM: Cancer cell inoculation is routinely used to evaluate novel therapeutic approaches in vivo. However, without reporter genes enabling deep tissue imaging, study of early tumor progression and therapeutic responses is often limited. We describe the establishment and characterization of two canine cancer cell lines stably expressing red fluorescence proteins as tools for later in vivo imaging. MATERIALS AND METHODS: Two red fluorescence cell lines were generated by plasmid transfection. Fluorescence protein expression was confirmed by flow cytometry and microscopy. Deep tissue imaging was demonstrated in mice using a NightOWL LB 983. Gene expression changes after transfection were analyzed by RNAseq. RESULTS: Both cell lines were detectable in vivo by subcutaneous injection of 1×106 cells. RNAseq revealed up to 2005 transfection-induced differentially expressed genes but no significant changes in cellular key pathways. CONCLUSION: The fluorescent cell lines provide a solid basis for future in vivo studies on canine cancer. PMID:34972712 | DOI:10.21873/invivo.12688 View on the web Inoreader.

Laser-projection endoscopes can address the need for direct calibrated measures; however, these systems are not widely available. This study presents the framework for an alternative indirect horizontal-plane calibration approach. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.
