Online ahead of print. ABSTRACT OBJECTIVE: The aim of this study was to investigate brain reorganization following cochlear implantation using electroencephalography, an implant-compatible technique to record electrical brain activity. METHODS: We investigated cortical plasticity in cochlear implant (CI) users using visual evoked potentials in response to visual motion changes. We estimated visual and auditory neural sources in CI users (n = 20) and normal hearing (NH) matched control participants (n = 22). RESULTS: Results showed intra-modal plasticity in the visual cortex of CI users, revealed by higher P1 and visual mismatch negativity amplitude, and greater contribution of the visual cortex during visual motion changes compared to NH controls. CONCLUSIONS: Our results suggest more efficient processing of visual information in CI users that may r eflect enhanced multimodal compensatory strategies during speech processing. SIGNIFICANCE: This study showcases an objective, implant-compatible method that could be used in a clinical setting to measure and longitudinally track cortical plastic changes, enabling a better understanding of the link between individual patterns of cortical plasticity and CI outcomes.

How Many Nodes to Take? Lymph Node Ratio Below 1/3 Reduces Papillary Thyroid Cancer Nodal Recurrence

xlomafota13 shared this article with you from Inoreader How Many Nodes to Take? Lymph Node Ratio Below 1/3 Reduces Papillary Thyroid Cancer Nodal Recurrence Via The Laryngoscope Introduction Papillary thyroid carcinoma (PTC) accounts for the majority of thyroid malignancies; risk of PTC recurrence over a 30-year period is approximately 30%, of which 70% occur as nodal metastases. Patients with nodal disease who are treated with therapeutic dissection are at higher risk for recurrence, but optimal nodal yield has not been defined. We aim to determine variables predictive of nodal recurrence of PTC within the first 5 years of surgery, with a focus on lymph node ratio (LNR), to inform clinical decision-making. Methods Retrospective chart review identified 41 patients with nodal recurrence of PTC and 284 without nodal recurrence following thyroid surgery from 2000 to 2015. Cohorts were compared with regards to clinical history, surgical findings, and tumor characteristics. Results The fraction of the patients who underwent therapeutic central or lateral lymph node dissection was significantly higher in the nodal recurrence cohort. Maximum tumor size, presence of extrathyroidal extension, largest lymph node focus, LNR, postoperative thyroglobulin level, and administration of postoperative radioactive iodine were significantly increased in the PTC nodal recurrence group. LNR greater than 0.3 held the highest level of significance as a binary cutoff and captured the larger proportion of patients in the nodal recurrence cohort (68.3%). Conclusion This study demonstrates characteristics to help assess risk of nodal recurrence of PTC and suggests LNR of lower than 0.3 is optimal to reduce risk of recurrence. The next steps include cohort studies to validate findings and weight variable analysis to optimize the extent of surgical therapeutic dissection.

Survival of adult patients with solid cancer

xlomafota13 shared this article with you from Inoreader Survival of adult patients with solid cancer in Reunion Island, 1998-2014 Via Association française pour l'étude du cancer Bull Cancer. 2022 Feb 26:S0007-4551(22)00068-6. doi: 10.1016/j.bulcan.2022.01.010. Online ahead of print. ABSTRACT INTRODUCTION: Population-based cancer survival is a major indicator of effectiveness of cancer management. This study is the first population-based study to estimate the net survival (NS) of adult cancer patients in Reunion Island, a French overseas department with distinctive epidemiological, cultural, and sociodemographic characteristics. METHODS: All adult incident cases (n=23,055) of invasive solid tumors diagnosed between 1998 and 2014 and registered in the Reunion Island Cancer Registry were included in the study. The Pohar-Perme estimator was used to estimate 1-, 3-, 5-, and 10-year NS. RESULTS: 5-year NS ranged from 7% (liver in women) to 97% (thyroid cancer in women) for cancers diagnosed between 2006 and 2014. For the most common cancers, the age-standardized 5-year NS of women was 81% for breast canc er, 58% for colorectal cancer and 62% for cervical cancer. For men, the age-standardized 5-year NS was 85% for prostate cancer, 12% for lung cancer, and 52% for colorectal cancer. Age-standardized 5-year NS increased slightly with the period of diagnosis (from 1998-2005 to 2006-2014) for prostate, breast, head and neck, lung, colorectal (women), and stomach (men) cancers, remained stable for colorectal (men) cancer, and decreased slightly for cervical and stomach (women) cancers. DISCUSSION: Overall, NS was lower in Reunion Island than in mainland France. While the epidemiological, cultural, and sociodemographic characteristics of the Reunionese population likely explain some of the observed differences compared to mainland France, site-specific studies are needed to explore the different determinants of survival in Reunion Island.

Thyroid and Parathyroid Conditions: Hyperthyroidism

xlomafota13 shared this article with you from Inoreader Thyroid and Parathyroid Conditions: Hyperthyroidism Via radioactive iodine FP Essent. 2022 Mar;514:11-17. ABSTRACT Hyperthyroidism is an excess in thyroid hormone production caused by such conditions as Graves disease, toxic multinodular goiter, and toxic adenoma. Overt hyperthyroidism is defined as a low or undetectable thyrotropin (TSH) level with elevated triiodothyronine (T3) or thyroxine (T4) values, whereas subclinical hyperthyroidism is defined as low or undetectable TSH with normal T3 and T4 levels. Symp toms of hyperthyroidism include nervousness, heat intolerance, weight loss, and fatigue. The long-term consequences of unmanaged or poorly managed hyperthyroidism include increased risk of all-cause mortality, cardiovascular events, atrial fibrillation, sexual dysfunction, and osteoporosis. Overt and subclinical hyperthyroidism can be managed effectively with antithyroid drugs (eg, propylthiouracil, methimazole) or with definitive therapies (eg, radioactive iodine ablation, thyroidectomy). Subclinical hyperthyroidism is not always treated, although close monitoring is needed to prevent disease complications or progression to overt hyperthyroidism. Treatment for subclinical hyperthyroidism is recommended for patients 65 years or older with TSH levels lower than 0.10 mIU/L. Treatment also is recommended for symptomatic patients or those with cardiac or osteoporotic risk factors. Thyroid storm is a life-threatening complication of unmanaged or inadequately managed hyperthyroidism that warrants urgent treatment in a hospital setting. PMID:35235281 View on the web Inoreader.

Asiatic acid improves high-fat-diet-induced osteoporosis in mice via regulating SIRT1/FOXO1 signaling and inhibiting oxidative stress

xlomafota13 shared this article with you from Inoreader Asiatic acid improves high-fat-diet-induced osteoporosis in mice via regulating SIRT1/FOXO1 signaling and inhibiting oxidative stress Via Cellular and Molecular Biology Histol Histopathol. 2022 Mar 1:18446. doi: 10.14670/HH-18-446. Online ahead of print. ABSTRACT Asiatic acid can attenuate osteoporosis through suppressing adipogenic differentiation and osteoclastic differentiation. Oxidative stress enhances osteoclastic differentiation but represses osteogenic differentiation to promote osteoporosis. However, the role and mechanism of asiatic acid in osteoporosis have not been reported. Firstly, mice were fed with high-fat-diet (HFD) with or without asiatic acid for 16 weeks. Data from an automatic biochemical analyzer showed that HFD induced down-regulation of high-density lipoprotein (HDL) and an increase of serum levels of triglyceride (TG), total cholesterol (TC) and low-density lipoprotein (LDL). However, asiatic acid administration attenuated the decrease of HDL and increase of serum TG, TC and LDL in osteoporotic mice. Secondly, HFD induced high levels of malondialdehyde (MDA) and reactive oxyg en species (ROS), low levels of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in osteoporotic mice. However, the levels of MDA, ROS, SOD and GSH-Px in osteoporotic mice were reversed by asiatic acid administration. (this section is unclear and requires revision) Asiatic acid administration reduced expression of c-telopeptide of type 1 collagen (CTX-1), enhanced alkaline phosphatase (ALP) and procollagen type 1 N-terminal propeptide (P1NP) in HFD-induced osteoporotic mice. (this section is unclear and requires revision) Thirdly, asiatic acid promoted calcium deposition in bone marrow cells and osteogenic differentiation in osteoporotic mice, but decreased ALP in bone marrow cells. Lastly, asiatic acid enhanced SIRT1 and nuclear FOXO1 (Nu-FOXO1) expression, while it reduced Acetyl FOXO1 (Ac-FOXO1) in osteoporotic mice. In conclusion, asiatic acid might inhibit oxidative stress and promote osteogenic differentiation through activating SIRT1/FOXO1 to attenuate HFD-induc ed osteoporosis in mice.

Comparison Between Different Approaches Applied in Pediatric Adenoidectomy: A Network Meta-Analysis

xlomafota13 shared this article with you from Inoreader Comparison Between Different Approaches Applied in Pediatric Adenoidectomy: A Network Meta-Analysis Via otol rhinol Ann Otol Rhinol Laryngol. 2022 Feb 28:34894221081612. doi: 10.1177/00034894221081612. Online ahead of print. ABSTRACT OBJECTIVE: Adenoidectomy is a surgical procedure most frequently performed by otolaryngologists. However, there are no universally accepted guidelines for the choice of the surgical approach in specific circumstances. Therefore, a network meta-analysis (NMA) is needed to summarize existing studies and provide more evidence-based medical guidelines. METH ODS: A systematic search of the literature was conducted in the Cochrane Central Register of Controlled Trials, PubMed, and EMBASE databases from inception to 31 July 2021. A network meta-analysis of operating time, intraoperative blood loss, postoperative pain score, and incidence of postoperative residual tissue was performed. RESULTS: A total of 20 studies with 2329 patients were included. Four common surgical approaches, including powered vacuum shaver adenoidectomy (PVSA), plasma field ablation adenoidectomy (PFAA), curettage adenoidectomy (CUA), and suction diathermy adenoidectomy (SDA), were compared for operative time, intraoperative blood loss, postoperative pain score, and incidence of postoperative residual tissue. There were no significant differences between the surgical techniques for the 3 endpoints, operative time, intraoperative blood loss, and incidence of postoperative residual tissue. The data showed lower postoperative pain scores for PFAA than for CUA (MD = -3.45, 95% CI [-6.01, -0.95]). There were no significant differences in other surgical approaches for postoperative pain scores. CONCLUSION: There were no significant differences between PVSA, PFAA, CUA, and SDA for operative time, intraoperative blood loss, and incidence of postoperative residual tissue. PFAA had advantages over CUA for postoperative pain scores. PMID:35227080 | DOI:10.1177/00034894221081612 View on the web Inoreader. Take back control of your news feed.

Anatomical variations of the branches from left colic artery and middle colic artery at splenic flexure

xlomafota13 shared this article with you from Inoreader Anatomical variations of the branches from left colic artery and middle colic artery at splenic flexure Via radiol anat Surg Radiol Anat. 2022 Mar 1. doi: 10.1007/s00276-022-02898-8. Online ahead of print. ABSTRACT BACKGROUND: Variations of the vasculature at splenic flexure by left colic artery (LCA) and middle colic artery (MCA) remain ambiguous. OBJECTIVES: This study aim to investigate the anatomical variations of the branches from LCA and MCA at splenic flexure area. METHODS: Using ultra-thin CT images (0.5-mm thickness), we traced LCA and MCA till their merging site with par acolic marginal arteries through maximum intensity projection (MIP) reconstruction and computed tomography angiography (3D-CTA). RESULTS: A total of 229 cases were retrospectively enrolled. LCA ascending branch approached upwards till the distal third of the transverse colon in 37.6%, reached the splenic flexure in 37.6%, and reached the lower descending colon in 23.1%, and absent in 1.7% of the cases. Areas supplied by MCA left branch and aMCA were 33.2%, 44.5% and 22.3% in the proximal, middle and distal third of transverse colon of the cases, respectively. The accessory MCA separately originated from the superior mesenteric artery was found in 17.9% of the cases. Mutual correlation was found that, when the LCA ascending branch supplied the distal transverse colon, MCA left branch tended to feed the proximal transverse colon; when the LCA ascending branch supplied the lower part of descending colon, MCA left branch was more likely to feed the distal third of transverse colon . CONCLUSIONS: Vasculature at splenic flexure by LCA and MCA varied at specific pattern. This study could add more anatomical details for vessel management in surgeries for left-sided colon cancer.

Graves' disease in children and adolescents in Iceland

xlomafota13 shared this article with you from Inoreader Graves' disease in children and adolescents in Iceland Via radioactive iodine Laeknabladid. 2022 Mar;108(3):123-129. doi: 10.17992/lbl.2022.03.680. ABSTRACT INTRODUCTION: Graves' disease is an autoimmune disease in which autoantibodies cause an increase in the production of thyroid hormones, and is the most common cause of thyrotoxicosis in children. Symptoms in children are often more obscure than in adults. The aim of the study is to assess the incidence of Graves' disease in children and adolescents in Iceland over the span of two decades (2001-2021), and furthermore to investigate if the incidence rate has increased, as well as to describe treatment options and disease recurrence. MATERIAL/METHODS: This retrospective descriptive study included all children diagnosed with Graves' disease in the years 2001-2021 in Iceland. Information was obtained from the Directorate of Health's drug database and from ICD-10 diagnoses at Landspítali - The National University Hospital. RESULTS: In total, 57 children and adolescents were diagnosed with Graves', the overall incidence rate was 3.5/100,000 person-years. Gender ratio was 1:2.7 (male : female) and the mean age at diagnosis was 13.6 for boys and 13.9 years for girls. Of those 12 individuals currently receiving drug therapy (21.8%), four patients have had disease relapse. Thirteen patients reached an euthyroid state with medication (23.7%), 25 received treatment with radioactive iodine (45.5%) and 5 underwent surgery (9.1%). Boys were more likely to relapse. Disease recurrence w as 31.8%. CONCLUSION: The incidence of Graves' disease did not increase during the study period. The disease was more common in girls, although the gender ratio was lower than expected. Antithyroid drugs were the first choice in treatment and radioactive iodine was the most common permanent treatment option. Disease recurrence was common. A possible relationship between the duration of the original drug therapy and disease recurrence should be investigated. PMID:35230257 | DOI:10.17992/lbl.2022.03.680 View on the web Inoreader.

Transoral robotic surgery for the identification of unknown primary head and neck squamous cell carcinomas: Its effect on the wait and the weight

xlomafota13 shared this article with you from Inoreader Transoral robotic surgery for the identification of unknown primary head and neck squamous cell carcinomas: Its effect on the wait and the weight Via Head & Neck Abstract Background Neck carcinoma of unknown primary (CUP) is a frequent scenario. Transoral robotic mucosectomies (TORM) of pharynx have increased rate of primary identification, but come with cost of treatment delay. Methods We reviewed patients who underwent CUP protocol from 2014 to 2020. Patients with cervical nodes carcinoma and failure to localize a primary source were classified as CUP. We determined primary identification rate and postoperative complications. Results We included 65 patients underwent TORM. Surgical approach consisted of lingual and/or palatine tonsillectomies. The primary detection rate was 49.2%. Average weight reduction was 2.5 ± 4.3 kg. The average number of days from consultation to definitive treatment was 52.2 ± 18.3. Conclusion A systematic approach to patients with CUP showed a promising primary identification rate compared to panendoscopy alone. TORM carries a small risk of complications. The benefits of primary identification must be weighed with the morbidity and delay to definitive treatment. View on the web Inoreader. Take back control of your news feed.
