Days alive and out of hospital following transoral robotic surgery: Cohort study of 262 patients with head and neck cancer

xlomafota13 shared this article with you from Inoreader Days alive and out of hospital following transoral robotic surgery: Cohort study of 262 patients with head and neck cancer Via Head & Neck Abstract Background Days alive and out of hospital (DAOH) is a validated outcome in clinical trials, since it reflects procedure-associated morbidity and mortality. Transoral robotic surgery (TORS) has become a widely adopted procedure with increasing demand for knowledge and data on morbidity. Methods Retrospective single-center assessment of a prospective TORS database comprising patients treated for malignancy between 2013 and 2018 using DAOH to describe procedure- and disease-related morbidity the first 12-postoperative months. Results For 262 patients, median DAOH365 was 357 days (IQR 351–360). Indications for TORS were (i) primary curative resection (61%), (ii) salvage resection (15%), and (iii) diagnostic work-up of cancer of unknown primary in the head and neck (24%). Median DAOH365 was 359 days (IQR 351–361 days), 348 days (IQR 233–355), and 357 days (351–361), respectively. Pneumonia had the highest impact in DAOH365 reduction. Conclusion Total median DAOH365 after TORS was 357 days. The main cause leading to DAOH365 reduction was pneumonia. View on the web Inoreader. Take back control of your news feed.

Massive Cervical Lymphadenopathy Post-COVID-19 Vaccination

xlomafota13 shared this article with you from Inoreader Massive Cervical Lymphadenopathy Post-COVID-19 Vaccination Via ear nose throat Ear Nose Throat J. 2021 Oct 2:1455613211048984. doi: 10.1177/01455613211048984. Online ahead of print. ABSTRACT The coronavirus disease 2019 (COVID-19) is a global pandemic caused by severe acute respiratory syndrome coronavirus 2. Rapid spread with rampant growth of cases and deaths brought forth an urgent need for novel therapies including vaccinations. The mRNA vaccines for COVID-19 disease have been implemented at an unprecedented scale in an effort to combat the unrelen ting pandemic. Such a massive scale vaccination program is bound to coincide with adverse events related to treatment. We present a case of massive cervical lymphadenopathy in a 58-year-old male patient post-Moderna COVID-19 vaccination. Additional investigations did not identify malignancy and he was diagnosed with vaccine-related lymphadenopathy. Patient significantly improved with corticosteroid treatment within 2 days of admission. Lymphadenopathy is reported as the second most common local reaction to the Moderna vaccine. Promoting knowledge of this side effect, particularly in the setting widespread vaccination efforts, would allow for better management of cases, especially in relation to oncologic patients.

Resolvin D2 suppresses NLRP3 inflammasome by promoting autophagy in macrophages

xlomafota13 shared this article with you from Inoreader Resolvin D2 suppresses NLRP3 inflammasome by promoting autophagy in macrophages Via Experimental and therapeutic medicine Exp Ther Med. 2021 Nov;22(5):1222. doi: 10.3892/etm.2021.10656. Epub 2021 Aug 26. ABSTRACT Inflammasome, a multiprotein complex that regulates interleukin (IL)-1β secretion and pyroptosis, participates in numerous inflammatory diseases, including sepsis, atherosclerosis and type-2 diabetes. Investigating the inflammasome regulation is therefore crucial to understand the inflammasome activation and develop treatment for the related diseases. In addition, it remains unknown how the inflammasome is naturally suppressed during the inflammatory process. The present study aimed to investigate the role of resolvin D2 (RvD2), an innate suppressor of inflammation produced from essential ω3-polyunsaturated fatty acids, in the activation of the inflammasome via in vitro and in vivo experiments. The effects of RvD2 on the cytokine production of inflammasome-related peritonitis were determined, and the NLRP3 inflammasome activation was investigated in the presence of RvD2. Moreover, the potential mechanisms underlying RvD2 in NLRP3 inflammasome regulation through autophagy and proteasome were investigated. The results of the present study demonstrated that RvD2 suppressed inflammasome-mediated peritonitis in vivo and regulated the NLR family pyrin domain containing 3 (NLRP3) inflammasome, but not in absent in melanoma 2 (AIM2), NLR family CARD domain containing 4 (NLRC4) inflammasomes. Mechanistically, RvD2 was found to promote the degradation of NLRP3 through autophagy, and the inhibition of autophagy could reverse the RvD2-mediated suppression of NLRP3 inflammasome in vitro and partially reverse the inflammasome-mediated peritonitis in vivo. In summary, the present study reported the negative regulation of NLRP3 inflammasome activation by RvD2. The findings from this study may extend the knowledge of the innate regulation of inflammasome and highlight a possible target for inflammasome-r elated diseases.

Quercetin suppresses inflammatory cytokine production in rheumatoid arthritis fibroblast-like synoviocytes

xlomafota13 shared this article with you from Inoreader Quercetin suppresses inflammatory cytokine production in rheumatoid arthritis fibroblast-like synoviocytes Via Experimental and therapeutic medicine Exp Ther Med. 2021 Nov;22(5):1260. doi: 10.3892/etm.2021.10695. Epub 2021 Sep 6. ABSTRACT Rheumatoid arthritis (RA) is a chronic, progressive and systemic autoimmune disease mainly characterized by symmetric multijoint synovitis. Quercetin has anti-inflammatory, anti-oxidation and immune regulation activities, and therefore shows high medicinal value. The present study aimed to observe the effect of quercetin on fibroblast-like synoviocytes (FLSs) in RA. Rheumatoid arthritis fibroblast-like synoviocytes (RAFLSs) were pretreated with 50 nmol/l quercetin for 2 h and were then stimulated using TNF-α for 24 h for subsequent experiments. RAFLSs were transfected with short interfering (si)-X-inactive specific transcript (XIST), microRNA (miR)-485 mimic, miR-485 inhibitor or si-PSMB8 or combination. ELISA, PCR and western blotting was used to evaluate the effect of quercetin on RAFLSs treated with TNF-α. It was revealed that quercetin inhib ited the production of inflammatory cytokines and the expression of XIST in RAFLSs induced by TNF-α. Bioinformatics analysis indicated that XIST acted as a sponge for miR-485 and that proteasome subunit β type-8 (PSMB8) was a direct target of miR-485. Moreover, PSMB8 functioned as a suppressor in inflammatory cytokine production of RAFLSs induced by TNF-α. Overall, quercetin was observed to inhibit the production of inflammatory cytokines and the expression of XIST in RAFLSs induced by TNF-α. Moreover, XIST-silencing could suppress the inflammatory reaction by sponging miR-485 in cells treated with TNF-α. Altogether, quercetin could suppress the development of RA in vitro.

Construction of a new cervical anatomically adaptive titanium mesh cage based on measurements of cervical geometry: A morphological and cadaveric study

xlomafota13 shared this article with you from Inoreader Construction of a new cervical anatomically adaptive titanium mesh cage based on measurements of cervical geometry: A morphological and cadaveric study Via Experimental and therapeutic medicine Exp Ther Med. 2021 Nov;22(5):1256. doi: 10.3892/etm.2021.10691. Epub 2021 Sep 3. ABSTRACT Mismatch between the titanium mesh cage and cervical geometries is an important factor that induces subsidence in anterior cervical corpectomy and fusion (ACCF). The aim of the present study was to construct a new quadrate anatomically adaptive titanium mesh cage (AA-TMC) that matches well with the cervical geometries and segmental alignment in one- and two-level ACCF. Computed tomography (CT) scans of 54 individuals were used to measure the cervical endplate geometries. X-rays of 74 young individuals were used to measure the intervertebral body angle (IBA) and intervertebral body height (IBH) of the surgical segments. The AA-TMC was designed based on these measured parameters. A total of 18 cervical cadaveric specimens underwent successive one- and two-level ACCF using the AA-TMC. Postoperatively, the specimens underwent CT scanning to assess the degree of matching of the TMC-endplate interface (TEI), IBA and IBH. A TEI interval <0.5 mm was considered well matching. In the sagittal plane, 93.8% of the inferior endplates were arched, whereas 94.8% of the superior endplates were flat. In the coronal plane, 82.9% of the inferior endplates and 93.8% of the superior endplates were flat. A total of 91.7 and 94.4% of the TEIs were well matched in one- and two-level ACCF, respectively. The postoperative IBA and IBH values were consistent with the values of young individuals. The AA-TMC achieved good matching with cervical geometries and segmental alignment in one- and two-level ACCF, and is proposed for use in ACCF to increase the contact at the TEI and achieve sufficient lordosis restoration.

xlomafota13 shared this article with you from Inoreader Falx Cerebelli Meningioma: Case Report of a Rarely Occurring Tumor, Management Nuances, and Literature Review Via leak of cerebrospinal fluid J Neurol Surg Rep. 2021 Sep 29;82(3):e32-e35. doi: 10.1055/s-0041-1735905. eCollection 2021 Jul. ABSTRACT The falx cerebelli is a small crescent fold of dura mater that is attached to the internal occipital crest and projects forward into the posterior cerebellar notch between the cerebellar hemispheres. We report a rare case of a 61-year-old female who presented with a 1-month history of headache and gait instability. Imaging findings were suggestive of a meningioma arising from the falx cerebelli. Complete surgical resection was achieved with a standard posterior fossa midline approach. Duraplasty was performed using animal allograft dura (Duraguard) and additional layers of oxidized cellulose preparation (Surgicel), fibrin sealant, and nonsuturable collagen matrix (Duragen) were utilized to reduce the risk of a cerebrospinal fluid leak. Pathology confirmed a World Health Organization (WHO) grade-I meningioma. Postoperatively, patient with asymptomatic thrombosis of the left transverse/sigmoid sinuses and later with a pseudomeningocele managed with a lumbar drain. To our knowledge, this is the second documented case in the literature. We discuss intraoperative nuances and unique aspects in the postoperative care and management of these patients.
