xlomafota13 shared this article with you from Inoreader Deacetylated Sp1 improves β-glycerophosphate-induced calcification in vascular smooth muscle cells Via Experimental and therapeutic medicine Exp Ther Med. 2021 Oct;22(4):1152. doi: 10.3892/etm.2021.10586. Epub 2021 Aug 10. ABSTRACT The aging of the population has led to an annual increase in the incidence of vascular calcification (VC). Specific protein 1 (Sp1) is a transcriptional activator that serves an important role in VC. The deacetylation of transcription factors represses their binding to the promoters of downstream genes, thereby causing their downregulation. The present study aimed to investigate the role of deacetylated Sp1 in the development of VC. In the present study, western blotting and immunoprecipitation (IP) were performed to detect the protein levels of acetylated Sp1. Western blotting and immunofluorescence staining were used to analyze phenotypic switching in vascular smooth muscle cells (VSMCs). Alizarin red S, alkaline phosphatase (ALP) activity and calcium content assays were used to assess calcium deposition in VSMCs. Western blotting, flow cytomet ry, TUNEL staining and caspase3 activity assay were used to evaluate apoptosis of VSMCs. Chromatin immunoprecipitation (ChIP) assay was used to detect Sp1 binding to the BMP2 promoter. The results indicated that, in a β-glycerophosphate (β-GP)-induced VSMC calcification model, the level of acetylated Sp1 was increased. Western blotting and immunofluorescence staining results showed that, compared with the Sp1 overexpression group (Sp1-WT), deacetylated Sp1 (Sp1-K704A) downregulated the expression of osteogenic markers runt-related transcription factor 2 (Runx2) and bone morphogenetic protein 2 (BMP2), and upregulated the expression of contraction marker α-smooth muscle actin (α-SMA) and calponin 1. In addition, deacetylated Sp1 also reduced the ALP activity and calcium content of calcified VSMCs, and the Alizarin red S assay revealed that the calcium crystallization of Sp1-K704A group was markedly decreased. Western blotting, flow cytometry, TUNEL staining and caspase-3 activity assay were detected to indicate that the B-cell lymphoma 2 (Bcl-2)/Bcl-2-associated X protein ratio was increased, and caspase-3 activity and the apoptotic rate of VSMCs were decreased, in the Sp1-K704A group, as compared with the Sp1-WT group. ChIP assay revealed that Sp1 binding to the BMP2 promoter was downregulated in the Sp1-K704A group, compared with that in theSp1-WT group. In conclusion, a deacetylated mutant of Sp1 decreased Sp1 binding to the BMP2 promoter, thus decreasing apoptosis, phenotypic switching and calcium deposition in calcified VSMCs. This finding may indicate potential therapeutic targets for VC. PMID:34504597 | PMC:PMC8394101 | DOI:10.3892/etm.2021.10586 View on the web Inoreader. Take back control of your news feed.

Auswirkungen der COVID-19-Pandemie auf die logopädische Therapie von Kindern mit einer Sprachentwicklungsstörung

xlomafota13 shared this article with you from Inoreader Auswirkungen der COVID-19-Pandemie auf die logopädische Therapie von Kindern mit einer Sprachentwicklungsstörung Via Laryngo-Rhino-Otologie Laryngorhinootologie DOI: 10.1055/a-1613-5747 Hintergrund Im Dezember 2019 begann sich die COVID-19-Pandemie weltweit auszubreiten und sorgte für massive Einschränkungen im täglichen Leben. Viele Bildungseinrichtungen und logopädische Praxen wurden vorübergehend geschlossen (sog. Lockdown). Kinder mit einer Sprachentwicklungsstörung waren gezwungen, ihre Therapie zu pausieren. Ziel dieser Studie war es zu beschreiben, ob und wie die logopädische Therapie während des Lockdowns durchgeführt wurde und welche psychische Belastung für die betroffenen Eltern damit verbunden war. Material und Methoden Eltern von Kindern mit einer Sprachentwicklungsstörung wurden über die Therapie ihres Kindes während des Lockdowns und über ihre damit verbundenen Ängste und Sorgen befragt. Ergebnisse Bei 17 Patienten wurde die Sprachtherapie während des Lockdowns pausiert, während 20 Patienten ihre Therapie fortsetzen konnten. Kinder, die eine andere Sprache als Deutsch sprachen, hatten ein höheres Risiko, dass ihre Therapie pausiert wurde (Odds Ratio (OR) 5,11; 95 %-Konfidenzintervall (KI) 1,09–32,54). Eltern, deren Kinder während des Lockdowns keine Sprachtherapie erhielten, machten sich mehr Sorgen um die Entwicklung ihres Kindes. Schlussfolgerungen Es gibt kein generelles Konzept, wie Logopädie während eines Lockdowns sicher durchgeführt werden kann. Mögliche Barrieren für die Gesundheitsversorgung könnten während der Pandemie stärker ausgeprägt sein. Die betroffenen Eltern erleben eine höhere psychosoziale Belastung.

Effect of the combination of astragaloside IV and Panax notoginseng saponins on pyroptosis and necroptosis in rat models of cerebral ischemia-reperfusion

xlomafota13 shared this article with you from Inoreader Effect of the combination of astragaloside IV and <em>Panax notoginseng</em> saponins on pyroptosis and necroptosis in rat models of cerebral ischemia-reperfusion Via Experimental and therapeutic medicine Exp Ther Med. 2021 Oct;22(4):1123. doi: 10.3892/etm.2021.10557. Epub 2021 Aug 4. ABSTRACT Pyroptosis and necroptosis are closely associated with the mechanism underlying cerebral ischemia-reperfusion (I/R) injury. The combination of astragaloside IV (AST IV) and Panax notoginseng saponins (PNS) has remarkable effects on the alleviation of cerebral I/R damage. However, whether inhibition of pyroptosis and necroptosis is the mechanism underlying the beneficial effects of this drug combination on cerebral I/R injury remains unclear. To explore the effects and mechanisms of drug treatment, middle cerebral artery occlusion was performed to induce I/R injury in rats, which was verified based on neurological deficit score (NDS), infarct volume and H&E staining. Activation of pyroptosis and necroptosis was detected by western blot analysis of associated proteins. The results of the present study demonstrated that treatment with AST IV and PNS, either alone or in combination, significantly reduced the NDS, cerebral infarct volume and cell injury rate in the cerebral cortex of rats. The treatments also improved pathological injury to the cerebral cortex and reduced the levels of proteins associated with pyroptosis and necroptosis. These effects were stronger in the combination drug group compared with groups treated with a single drug alone. The findings of the present study suggested that the combination of AST IV and PNS exhibited stronger neuroprotective effects in I/R injury than either drug alone, and that the underlying mechanism was associated with inhibition of pyroptosis and necroptosis.

ABSTRACT The relevance of the study is due to the need to improve the methods of managing patients after reconstructive surgery on the larynx and trachea. OBJECTIVES: To optimize the management of wounds after tracheostomy and/or reconstuctive operations on larynx and trachea on the basis of use of modern dressings in the inpatient and outpatient settings. MATERIAL AND METHODS: The patients were divided into two: group I tracheostomy after reconstructive operations on the larynx and trachea. The postoperative area was ligated with drugs based on sodium alginate. Tracheostomy of group II patients was carried out according to the standard technique. RESULTS: In the first group of patients, postoperative wounds healed by primary intention on the 5-6th day after the operation in patients with bilateral paralysis of the larynx and on the 8-10th day in patients with chronic cicatricial stenosis of the larynx and trachea. In group II, postoperative wounds in the tracheostomy foramen area healed on day 7 in patients with bilateral paralysis of the larynx and on days 10-14 in patients with chronic cicatricial stenosis of the larynx and trachea. CONCLUSIONS: The Proposed algorithm for the management of patients after reconstructive operations on the larynx and trachea, of tracheostomy have improved clinical outcomes after surgery and to reduce the economic costs for this group of patients.

Functional endoscopic sinus surgery in a patient with cystic fibrosis after lung transplantation

xlomafota13 shared this article with you from Inoreader Functional endoscopic sinus surgery in a patient with cystic fibrosis after lung transplantation Via Vestnik otorinolaringologii Vestn Otorinolaringol. 2021;86(4):73-78. doi: 10.17116/otorino20218604173. ABSTRACT Cystic fibrosis is genetic multisystem disorder with a predominant lesion of the respiratory tract. The duration and quality of life of these patients depends on the state of respiratory function. Progressive lung dysfunction is still the leading cause of mortality patients with cystic fibrosis. End-stage lung diseases in patients with cystic fibrosis, lung transplantation is a viable method of treatment. It has the ability to prolong life of these patients. Survival in cystic fibrosis has steadily increased medical treatment and post-transplant. Chronic rhinosinusitis (with nasal polys and without) impacts almost all cystic fibrosis patients, leading to significant reductions in quality of life. Chronic rhinosinusitis with nasal polyps is prevalent in the cystic fibrosis patients, and it is often a recalcitrant infection with multidrug resistant organi sms. Medical therapies such as nasal irrigations, nasal steroids, and antibiotics are critical for managing symptoms, but functional endoscopic sinus surgery is necessary for refractory cases. The unified airway hypothesis suggests that sanitation bacterial infection in the upper airway can also decrease bacterial burden in the lungs. The article presents a clinical case of successful endoscopic sinus surgery in a 15-year-old patient with chronic rhinosinusitis with nasal polyps and cystic fibrosis after lung transplantation. The intervention was performed under General anesthesia and controlled hypotension. Bilateral antrostomy, ethmoidectomy and Draf IIb frontal sinusotomy were performed by endoscopic endonasal approach. There were no intra - and post-operative rhinosurgical or lung complications. The follow-up period was 18 months. At present, there is no relapse of chronic polypous rhinosinusitis, and there are no indications for revision intervention.

xlomafota13 shared this article with you from Inoreader Foreign bodies of the esophagus in children Via Vestnik otorinolaringologii Vestn Otorinolaringol. 2021;86(4):46-49. doi: 10.17116/otorino20218604146. ABSTRACT OBJECTIVE: Of this study is to determine the optimal algorithm for active verification and treatment of children with foreign bodies of the esophagus, analysis of the causes and development of related complications. PATIENTS AND METHOD: The results of examination and treatment of 320 children with foreign bodies of the esophagus for the period from 2011 to 2017 were analyzed. The vast majority of patients (79.4%) were between 1 and 5 years old. The period from the moment of accidental ingestion of a foreign body to hospitalization ranged from 3 hours to 2 months. It was found that the x-ray method made it possible to confirm the presence of a foreign body in the esophagus in 89.1% of cases, to identify the nature of the radiopaque foreign body and associated complications in 100% of cases. RESULTS: In order to remove a foreign body, 314 emer gency endoscopic interventions were performed. In 79.6% of cases, a foreign body was localized in the upper third of the esophagus. Coins were the most frequently found foreign bodies of the esophagus (80.1%), the second place was taken by disk-type batteries (8.7%), and the third - by bones of various origin (4.5%). Among all foreign bodies, the most dangerous were disk batteries, causing serious complications in 72% of cases, the treatment of which requires the joint efforts of doctors of various specialties. The occurrence and severity of complications was directly dependent on the nature, size, location of fixation and the length of stay of a foreign body in the esophagus. CONCLUSION: Main conclusion of this study is that children with suspected foreign body of the esophagus need emergency examination and treatment exclusively in a multidisciplinary medical institution.

Infectious mononucleosis in practice of otorhinolaryngologist

xlomafota13 shared this article with you from Inoreader Infectious mononucleosis in practice of otorhinolaryngologist Via Vestnik otorinolaringologii Vestn Otorinolaringol. 2021;86(4):79-85. doi: 10.17116/otorino20218604179. ABSTRACT Infectious mononucleosis (IM) is an acute viral infection that usually occurs with fever, acute tonsillitis, affects lymph nodes, liver, spleen, and with specific changes in the hemogram. One of the most frequent symptoms of the disease is sore throat which leads people to otorhinolaryngologist. Several pathogens may be the cause of IM, but Epstein-Barr virus(EBV) plays a key role. EBV is a γ-herpes virus and about 90% of world`s population is infected with this one. Severe IM can lead to potential life-threating conditions, for example upper airway obstruction, spleen rupture. In addition to acute IM, EBV-infection can lead to a number of neoplastic and autoimmune diseases. Due to the non-specificity of IM symptoms and the emerging difficulties in laboratory and serological diagnosis of this disease, the problem of timely diagnosis and treatment in th is category of patients remains very relevant.

The rhinophyma through the prism of time

xlomafota13 shared this article with you from Inoreader The rhinophyma through the prism of time Via Vestnik otorinolaringologii Vestn Otorinolaringol. 2021;86(4):95-98. doi: 10.17116/otorino20218604195. ABSTRACT One of the frequent causes of a significant increase in the external nose, forming a persistent deformity of the face, as well as leading to a non-standard clinical picture is rhinophyma disease. The article considers some historical data, epidemiology, peculiarities of pathogenesis, as well as the basics of surgical treatment tactics along with possible preventive measures against rhinophyma. At present, the treatment of this pathology presents great difficulties. Despite the many surgical methods, rhinophyma is poorly treatable, often relapses and leaves no less noticeable disfigurement of the face in the postoperative period. In this regard, there is a constant search for new surgical methods, which has not only medical but also important social significance.

Hearing care aspects in universal face mask use during the COVID 19 pandemic

xlomafota13 shared this article with you from Inoreader Hearing care aspects in universal face mask use during the COVID 19 pandemic Via Vestnik otorinolaringologii Vestn Otorinolaringol. 2021;86(4):9-12. doi: 10.17116/otorino2021860419. ABSTRACT BACKGROUND: Typical cloth and medical masks, which are mandatory to wear during the COVID 19 pandemic, create visual barrier, obscure linguistic and nonverbal communication and interaction. Ski-slope hearing loss patients often don't admit their auditory insufficiency and do not use hearing aids due to acceptable speech intelligibility by using visual access to the mouth and other potential facial cues. PURPOSE: To assess the impact of universal face medical masks in public places on motivation to using hearing aids of patients with ski-slope hearing loss. PATIENTS AND METHODS: All the 504 patients (18-65 years old), who applied for < hearing care assistance and for the first time bought hearing aid were included. 266 patients (group A) applied from June to November 2020, when wearing facial masks was mandatory; 238 patients (group B) appli ed from June to November 2019, when wearing facial masks wasn't required. In both groups patients, who fulfilled the following criteria, were selected: 1) binaural mild to severe sensorineural ski-slope hearing loss lasting more than 3 years; 2) no progression of hearing loss within the last 3 years; 3) pure tone audiometry <20 dB HL at 125-1000 Hz frequencies; 4) hearing care with mono- or binaural hearing aids with the receiver-in-the-canal open-type. Questionnaires were administered to eligible patients in group A to assess the motivational components of acquiring hearing aids. RESULTS AND DISCUSSION: In group A, 74 (28%) patients received hearing aids according to the inclusion criteria, and in group B, 46 (19%) patients received hearing aids (p=0.033). Significant factors determining hearing aid acquisition were lack of visual contact when wearing a mask, communication difficulties in noisy environments and lack of intelligibility in a concert hall or lecture. CONCLUSION: Patients' motivation to hearing care grows in mandatory wearing facial masks conditions during the COVID-19 pandemic leading to an increase in patients using hearing aids.
