Online ahead of print. ABSTRACT Adipose tissue is a dynamic organ in the endocrine system that can connect organs by secreting molecules and bioactive. Hence, adipose tissue really plays a pivotal role in regulating metabolism, inflammation, energy homeostasis, and thermogenesis. Disruption of hub bioactive molecules secretion such as adipokines leads to dysregulate metabolic communication between a dipose tissue and other organs in non-communicable disorders. Moreover, a sedentary lifestyle may be a risk factor for adipose tissue function. Physical inactivity leads to fat tissue accumulation and promotes obesity, Type 2 diabetes, cardiovascular disease, neurodegenerative disease, fatty liver, osteoporosis, and inflammatory bowel disease. On the other hand, physical activity may ameliorate and protect the body against metabolic disorders, triggering thermogenesis, metabolism, mitochondrial biogenesis, β-oxidation, and glucose uptake. Furthermore, physical activity provides an inter-organ association and cross-talk between different tissues by improving adipose tissue function, reprogramming gene expression, modulating molecules and bioactive factors. Also, physical activity decreases chronic inflammation, oxidative stress and improves metabolic features in adipose tissue. The current review focuses on the beneficial effect of physical activity on the cardiovascular, locomotor, digestive, and nervous systems. In addition, we visualize protein-protein interactions networks between hub proteins involved in dysregulating metabolic induced by adipose tissue.

Chaos Behavior Analysis of Alaryngeal Voices Including Esophageal (SE) and Tracheoesophageal (TE) Voices

xlomafota13 shared this article with you from Inoreader Chaos Behavior Analysis of Alaryngeal Voices Including Esophageal (SE) and Tracheoesophageal (TE) Voices Via Folia Phoniatrica et Logopaedica ABSTRACT Hypothesis/Objectives This study's objective was to develop a method to the evaluate the chaotic characteristic of alaryngeal speech. The proposed method will be capable of distinguishing between normal and alaryngeal voices, including esophageal (SE) and tracheoesophageal (TE) voices. It has been previously shown that alaryngeal voices exhibit chaotic characteristics due to the aperiodicity of their signals. The proposed method will be applied for future use to quantify both chaos behavior and the difference between SE and TE voices. Study Design A total of 74 voice recordings including 34 normal and 40 alaryngeal (26 esophageal (SE) and 14 tracheoesophageal (TE)) were used in the study. Voice samples were analyzed to distinguish alaryngeal voices from normal voices and investigate different chaotic characteristics of SE and TE speech. Methods A chaotic distribution detection-based method was used to investigate the chaos behavior of alaryngeal voices. This chaos behavior was used to detect the difference between SE and TE voice types. Quantification of the chaos behavior (CB) parameter was performed. Statistical analyses were used to compare the results of the CB analysis for both the SE and TE voices. Results Statistical analysis revealed that CB effectively differentiated between all normal and alaryngeal voice types (P View on the web Inoreader. Take back control of your news feed.

Challenges in Interpreting Thyroid Stimulating Hormone Results in the Diagnosis of Thyroid Dysfunction

xlomafota13 shared this article with you from Inoreader Challenges in Interpreting Thyroid Stimulating Hormone Results in the Diagnosis of Thyroid Dysfunction Via Journal of Thyroid Research The pituitary hormone, thyrotropin (TSH), is regarded as the primary biomarker for evaluating thyroid function and is useful in guiding treatment with levothyroxine for patients with hypothyroidism. The amplified response of TSH to slight changes in thyroid hormone levels provides a large and easily measured signal in the routine care setting. Laboratories provide reference ranges with upper and lower cutoffs for TSH to define normal thyroid function. The upper limit of the range, used to diagnose subclinical (mild) hypothyroidism, is itself a matter for debate, with authoritative guidelines recommending treatment to within the lower half of the range. Concomitant diseases, medications, supplements, age, gender, ethnicity, iodine status, time of day, time of year, autoantibodies, heterophilic ant ibodies, smoking, and other factors influence the level of TSH, or the performance of current TSH assays. The long-term prognostic implications of small deviations of TSH from the reference range are unclear. Correction of TSH to within the reference range does not always bring thyroid and other biomarkers into range and will not always resolve the patient's symptoms. Overt hypothyroidism requires intervention with levothyroxine. It remains important that physicians managing a patient with symptoms suggestive of thyroid disease consider all of the patient's relevant disease, lifestyle, and other factors before intervening on the basis of a marginally raised TSH level alone. Finally, these limitations of TSH testing mitigate against screening the population for the undoubtedly substantial prevalence of undiagnosed thyroid disease, until appropriately designed randomised trials have quantified the benefits and harms from this approach.

xlomafota13 shared this article with you from Inoreader Increasing the reliability of real-time electrocochleography during cochlear implantation: a standardized guideline 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 20. doi: 10.1007/s00405-021-07204-7. Online ahead of print. ABSTRACT PURPOSE: Electrocochleography (ECochG) measures electrical potentials generated by the inner ear in response to acoustic stimulation. Real-time (rt) recordings are increasingly used during cochlear implant (CI) surgeries to monitor the inner ear function. However, the performance of rt-ECochG is a delicate measurement procedure involving several pitfalls, which lead to inaccurate or invalid signal recordings in up to 20%. In order to use the technique routinely in CI candidates, an improvement in measurement reliability must be achieved. METHODS: In our prospective study, we systematically investigated potential pitfalls and error sources during rt-ECochG recordings. We performed experiments (i) on a head and torso simulator, (ii) on a whole-head cadaver specimen, (iii) as well as in vivo during rt-ECochG recordings in CI reci pients. After analyzing experiments i-iii, a standardized measurement procedure was developed. We followed this guideline in 10 CI recipients to test the measurement reliability. RESULTS: Besides improper installation, surgical and patient-specific factors influenced the measured signal. In particular, the unattenuated presentation of the acoustic stimulus was of importance. We summarized our findings in a standardized guideline. Following this guideline, we measured successful intraoperative ECochG recordings in 9/10 patients. CONCLUSIONS: Our error analysis improved the understanding of successful rt-ECochG measurements. When following our proposed guideline, we achieved more reliable intraoperative ECochG recordings.

Online ahead of print. ABSTRACT OBJECTIVE: To investigate the prognostic factors to developing parotid and neck metastasis in locally advanced and relapsed Cutaneous Squamous Cell Carcinoma (CSCC) of the head and neck region. METHODS: Single-center retrospective cohort study enrolling consecutive patients with advanced CSCC from 2009 to 2019. Seventy-four cases were identified. Study variables demographic data, clinical skin tumor stage, neck stage, parotid stage (P stage), surgical treatment features, and parotid, regional, and distant metastases. Survival measures: Overall Survival (OS) and Disease-Specific Survival (DSS). RESULTS: The study group included 72.9% men (median age, 67 years); 67.5% showed T2/T3 tumors, 90.5% comorbidities, 20.2% immunosuppressed, with median follow-up: 35.8 months. The most frequent skin primary wer e auricular and eyelid regions, 75% underwent primary resection with flap reconstruction. Parotid metastasis was present in 50%, 32.4% showing parotid extracapsular spread, multivariate analysis found OR = 37.6 of positive parotid metastasis evolving into positive neck metastasis, p = 0.001. Occult neck metastasis, neck metastasis, and neck extracapsular spread were observed in 13.5%, 51.3%, and 37.8%, respectively. Kaplan-Meier survival: Clinical T4 versus T1, p = 0.028, P1 stage: 30% and 5% survival at 5 and 10 years, P3 stage: 0%, p = 0.016; OS and DSS showed negative survival for the parotid metastasis group, p = 0.0283. CONCLUSION: Our outcomes support a surgically aggressive approach for locally advanced and relapsed CSCC, with partial parotidectomy for P0, total parotidectomy for P1-3, selective I-III neck dissection for all patients and adjuvant radiochemotherapy to appropriately treat these patients with advanced CSCC of the head and neck region.

Complications of Gastrostomy Tubes in Patients With Head and Neck Cancer

xlomafota13 shared this article with you from Inoreader Complications of Gastrostomy Tubes in Patients With Head and Neck Cancer Via The Laryngoscope Objectives Head and neck cancers (HNCs) include various malignant tumors of the upper aerodigestive tract. Due to their anatomical location, HNCs can cause obstruction, odynophagia, or trismus, leading to dysphagia. In addition, this patient group may be vulnerable to treatment side effects both by surgery and oncological treatment, exposing the patients to an even higher risk of malnutrition. The risk of malnourishment is often resolved by applying a feeding gastrostomy tube. The present study aims to identify complication rates after percutaneous endoscopic gastrostomy (PEG) and open gastrostomy (OG) in patients treated for HNC in a high-volume center. Study Design Retrospective cohort study. Methods A retrospective cohort study of all patients treated for a new diagnosis of HNC at the Department of Otorhinolaryngology and Head and Neck Surgery at Karolinska University Hospital between January 1, 2000 and December 31, 2018 in whom gastrostomy was performed. Results Regarding tumor location, 165 (56.7%) were in the pharynx, 68 (23.4%) in the oral cavity, 57 (19.6%) in the larynx, and 1 (0.3%) in the nasal cavity. PEG was performed in 240 (82.5%) and OG in 51 (17.5%) patients. The overall complication rate was 28.2%: 64 (26.7%) among PEG patients and 18 (35.3%) among OG patients. The incidence of major complications was 3.1%. Conclusions Our study confirms that enteral feeding via gastrostomy is a safe method, regardless of the technique used (PEG or OG), with a low rate of major complications and no mortality linked to the procedure.

Quality of life after tonsillectomy in adult patients with recurrent acute tonsillitis: a systematic review

xlomafota13 shared this article with you from Inoreader Quality of life after tonsillectomy in adult patients with recurrent acute tonsillitis: a systematic review 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 19. doi: 10.1007/s00405-022-07260-7. Online ahead of print. ABSTRACT PURPOSE: The aims of this systematic review were to (1) explore the evidence for improved quality of life (QOL) in adult patients undergoing tonsillectomy because of recurrent acute tonsillitis (RT) and (2) evaluate which set of guidelines for tonsillectomy in adult RT patients is preferable, using QOL as outcome measure. METHODS: A systematic search was conducted in the PubMed, Embase, and Scopus databases. RCT/cohort studies exploring the effect of elective tonsillectomy in adult RT patients using any QOL assessment tool no less than 6 months after surgery were included. Studies were divided into two guideline groups based on the number of tonsillitis episodes required for tonsillectomy (Group 1: ≥ 5; Group 2: ≤ 4). RESULTS: A total of 364 unique records were identified. Seven studies (n = 409 patients) were includ ed in a qualitative analysis and four studies were included in a meta-analysis. Patients' QOL rose significantly, primarily because of improvements in the general and physical domains. In the meta-analysis, 96% (293/304) of patients benefitted from tonsillectomy. Patients included in guideline Group 1 studies had significantly higher QOL scores (Glasgow Benefit Inventory (GBI) 39.6) compared to patients in Group 2 studies (GBI 24.9) (p < 0.001). CONCLUSION: Adult patients undergoing tonsillectomy because of RT reported improved QOL 6-84 months after surgery. The benefit of tonsillectomy was higher among patients in studies with a higher minimum number of tonsillitis episodes compared to those included in studies with less strict criteria. Whether the improved QOL outweigh the morbidity associated with surgery in both guideline groups remains unclear. PMID:35044507 | DOI:10.1007/s00405-022-07260-7 View on the web Inoreader.
