Online ahead of print. ABSTRACT Persistent primitive olfactory artery (PPOA) is a rare variation of the proximal anterior cerebral artery (ACA) that generally follows an extreme anteroinferior course and takes a hairpin turn before continuing to the A2 segment of the ACA (type 1). There are four other types of extremely rare variations. The type 4 variation continues to the accessory middle cerebral artery (MCA) instead of the ACA. Only a few cases have been reported. We herein report a case of type 4 PPOA in which the contralateral side of the accessory MCA arose from the fenestrated segment of the distal ACA. No similar cases were found in the relevant English-language literature. For the identification of these variations on MR angiography, volume-rendering images were superior to maximum-intensity-projection images.

MiR-337-3p suppresses migration and invasion of breast cancer cells by downregulating ESRP1

xlomafota13 shared this article with you from Inoreader MiR-337-3p suppresses migration and invasion of breast cancer cells by downregulating ESRP1 Via histochem Acta Histochem. 2021 Sep 1;123(7):151777. doi: 10.1016/j.acthis.2021.151777. Online ahead of print. ABSTRACT Breast cancer (BC) is a common malignant tumor in women, and a considerable number of studies show that aberrant expression of miRNA is correlated with BC development. By analyzing TCGA-BRCA database through bioinformatics method, this study disclosed that miR-337-3p was significantly low in BC tissue and might be a cancer inhibitor in BC. To explore the effect and po tential mechanism of miR-337-3p in BC, qRT-PCR was used in this study to indicate that the expression of miR-337-3p was downregulated in BC cells. Then, the effects of miR-337-3p on BC cells were detected by western blot, Cell Counting Kit-8 (CCK-8), wound healing and Transwell assays. After upregulating miR-337-3p expression, the cell viability, migration, invasion and epithelial-mesenchymal transition (EMT) of BC cells were markedly inhibited while cell apoptosis remarkably increased. Besides, it was predicted and identified by bioinformatics analysis and dual-luciferase assay that ESRP1 was a target gene of miR-337-3p. Finally, the progression and EMT of BC cells were promoted after upregulating ESRP1 expression level. However, upregulating miR-337-3p as well as ESRP1 reduced the promotion on the malignant phenotype of BC cells. This result revealed that miR-337-3p could inhibit ESRP1 expression to perform its biological functions. In conclusion, it was illustrated in this study that miR-337-3p is a tumor-inhibitor of BC and plays its regulatory role via its downstream gene ESRP1.

Identification of specific clinical risk factors associated with the malignant transformation of oral epithelial dysplasia

xlomafota13 shared this article with you from Inoreader Identification of specific clinical risk factors associated with the malignant transformation of oral epithelial dysplasia Via Head & Neck Abstract Background Factors that increase the risk of malignant transformation of oral epithelial dysplasia (OED) are not completely elucidated. Methods A retrospective chart review was performed assessing risk factors for transformation of OED, and cancer staging for transformed cases at Sunnybrook Health Sciences Centre. Results Two-hundred four patients were diagnosed with OED, and 16.7% (34) underwent malignant transformation. Risk factors associated with transformation included: heavy tobacco smoking, excessive EtOH consumption, non-homogenous leukoplakia, size >200 mm2, moderate dysplasia or greater than moderate, progression of dysplasia grades, and immunosuppression. Transformed cases followed for a dysplastic lesion were associated with a stage-I cancer diagnosis, and cancer cases with no prior biopsy were associated with a stage-IV diagnosis. Conclusions In addition to commonly cited risk factors, immunosuppression was associated with malignant transformation, including the use of topical steroids. Analyzing risk factors can help clinicians define risk of progression in patients with OED. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

Dysphagia in non-intubated patients affected by COVID-19 infection

xlomafota13 shared this article with you from Inoreader Dysphagia in non-intubated patients affected by COVID-19 infection 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. 2021 Sep 1:1-7. doi: 10.1007/s00405-021-07062-3. Online ahead of print. ABSTRACT PURPOSE: Patients affected by COVID-19 are assumed to be at high risk of developing swallowing disorders. However, to our best knowledge, data on the characteristics and incidence of dysphagia associated with COVID-19 are lacking, especially in non-intubated patients. Therefore, we investigated the onset of swallowing disorders in patients with laboratory-confirmed COVID-19 infection who have not been treated with invasive ventilation, in order to evaluate how the virus affected swallowing function regardless of orotracheal intubation. METHODS: We evaluated 41 patients admitted to the COVID department of our Hospital when they had already passed the acute phase of the disease and were therefore asymptomatic but still positive for SARS-CoV-2 RNA by RT-PCR. We examined patients' clinical history and performed the Volume-Visco sity Swallow Test (VVST). Each patient also answered the Swallowing Disturbance Questionnaire (SDQ). After 6 months, we performed a follow-up in patients with swallowing disorders. RESULTS: Eight of 41 patients (20%) presented with dysphagia symptoms during hospitalization and 2 of them (25%) still presented a SDQ high score and swallowing disorders with liquid consistency after 6 months. CONCLUSION: Non-intubated patients can experience various grades of swallowing impairment that probably directly related to pulmonary respiratory function alterations and viral direct neuronal lesive activity. Although these symptoms show natural tendency to spontaneous resolution, their impact on a general physical impaired situation should not be underestimated, since it can adversely affect patients' recovery from COVID-19 worsening health outcomes.

Iatrogenic Vocal Fold Paralysis: A Population-Based Cohort Study in Taiwan

xlomafota13 shared this article with you from Inoreader Iatrogenic Vocal Fold Paralysis: A Population-Based Cohort Study in Taiwan Via otol rhinol Ann Otol Rhinol Laryngol. 2021 Sep 1:34894211041226. doi: 10.1177/00034894211041226. Online ahead of print. ABSTRACT OBJECTIVE: Iatrogenic vocal fold paralysis is an important issue in laryngology, yet there are few population-based studies regarding the epidemiology. This study used a nationwide population-based claims database (the National Health Insurance Research Database) to investigate the epidemiology of iatrogenic unilateral and bilateral vocal fold paralysis (UVFP/ BVFP) among the general adult population in Taiwan. METHOD: This study analyzed patients (20-90 years old) who underwent thyroid, parathyroid, thoracic, cardiac, or anterior cervical spine operations with vocal fold paralysis among adults in Taiwan from January 1, 2007 to December 31, 2013. The codes for vocal fold paralysis were defined by International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM). Claims data in the Taiwan National Health Insurance Research Database were used. RESULTS: The most commonly performed operations which were related to vocal fold paralysis in Taiwan were, in descending order of frequency, thyroid, cervical spine, cardiac, thoracic (esophagectomy), and parathyroid operations. The operations that put laryngeal nerves at risk (ONRs) most commonly associated with a diagnosis of UVFP were, in descending order of frequency, thoracic, thyroid, parathyroid, cardiac, and cervical spine. For both UVFP and BVFP, the most commonly associated age group was 51 to 60. For both UVFP and BVFP, the more commonly associated sex was women. Increased length of stay was associated with a higher incidence of UVFP and BVFP. Charlson medical co-morbidity index (CCI) was not associated with UVFP but BVFP was associated with higher Charlson medical co-morbidity scores. CONCLUSIONS: Thyroid operations, age 51 to 60, longer hospital stays are associated with vocal fold paralysis. Overall women are more surgically affected than men. This is the first population-based study of iatrogenic vocal fold paralysis. PMID:34470521 | DOI:10.1177/00034894211 041226 View on the web Inoreader. Take back control of your news feed.

Intraoperative Parathyroid Hormone in Minimally Invasive Parathyroidectomy

xlomafota13 shared this article with you from Inoreader Intraoperative Parathyroid Hormone in Minimally Invasive Parathyroidectomy Via JAMA Otolaryngology–Head & Neck Surgery Online First To the Editor My attention was arrested by the article by Quinn et al on the use of intraoperative parathyroid hormone (ioPTH) in minimally invasive parathyroidectomy (MIP) for primary hyperparathyroidism (PHP). To our knowledge, it is the first meta-analysis on this topic showing a beneficial association of ioPTH with cure rates—98% vs 94.8% without ioPTH. It will have a considerable effect on surgical treatment for PHP. Nonetheless, I have some comments on the methodology, results, and conclusion of the trial. View on the web Inoreader.
