alexandrossfakianakis shared this article with you from Inoreader Predictive Value of Risk Factors for Pharyngocutaneous Fistula After Total Laryngectomy via The Laryngoscope Multiple patient-, disease-, and surgery-related factors are risk factors for pharyngocutaneous fistula. In particular, postoperative hypoproteinemia could be a good predictive factor for pharyngocutaneous fistula in patients undergoing total laryngectomy. Objectives To assess the predictive value of various risk factors for pharyngocutaneous fistula (PCF) after total laryngectomy. Methods The characteristics of each study were collected from six databases up to January of 2022. Risk for bias was assessed using the QUADAS-2 tool. Results A total of 58 studies in 9845 patients were included in the analysis. The incidence of PCF was 21.69%, 95% confidence intervals (CI) [0.20; 0.24] in the included studies. Age (OR = 1.33, 95% CI [1.12; 1.58]), postoperative anemia (OR = 2.29, 95% CI [1.47; 3.57]), diabetes mellitus (OR = 1.81, 95% CI [1.20; 2.71]), tumor site (above or below the glottis) (OR = 1.47, 95% CI [1.15; 1.88]), previous radiation therapy (OR = 2.06, 95% CI [1.56; 2.72]), previous tracheostomy (OR = 1.26, 95% CI [1.04; 1.53]), surgery timing (salvage vs. primary) (OR = 2.08, 95% CI [1.46; 2.97]), extended total laryngectomy (including pharyngectomy) (OR = 1.96, 95% CI [1.28; 3.00]), primary tracheoesophageal puncture (OR = 0.61, 95% CI [0.40; 0.93]), and postoperative hypoproteinemia (OR = 9.98, 95% CI [3.68; 27.03]) were significantly associated with the occurrence of PCF. In view of predictive ability, pos toperative hypoproteinemia showed the highest accuracy (sensitivity = 51%, specificity = 90%, area under the curve = 0.84). Conclusion Multiple patient-, disease-, and surgery-related factors are risk factors for PCF. In particular, postoperative hypoproteinemia could be a good predictive factor for PCF in patients undergoing total laryngectomy. Laryngoscope, 2022 View on Web

Morphology of Peri‐Implant Tissues around Permanent Prostheses with Various Emergence Angles Following Free Gingival Grafting

alexandrossfakianakis shared this article with you from Inoreader Morphology of Peri‐Implant Tissues around Permanent Prostheses with Various Emergence Angles Following Free Gingival Grafting via Journal of Prosthodontics Abstract Purpose To analyze the tissue morphology around implant-supported prostheses by digital technology and to evaluate the effect of prosthetic contours on the changes in tissues following free gingiva graft procedure. Material and Methods A total of 53 implants in 32 patients receiving free gingiva grafts were selected. These had previously presented insufficient keratinized mucosa width (KMW). At the follow-up visits (mean: 16.66 ±9.97 months), the implant position and tissue condition were documented with an oral scanner. Vertical soft tissue thickness (VT), measured from the implant-abutment connection to the marginal tissues, and horizontal soft tissue thickness (HT), at the level of the platform, were calculated. The VT, HT and emergence angle (EA) of prostheses were assessed by 3Shape analyzing software. The final KMW was measured by clinical assessment. Marginal bone loss (MBL) was calculated in the follow-up bitewing radiographs. Results The mean VT in the study was 2.65 ±0.75 mm at the mid-buccal sites, 3.74 ±1.22 mm at the mesial, 3.16 ±1.08 mm at the distal, and 2.53 ±0.92 at the mid-lingual aspects. The mid-buccal HT was 1.45 ±0.53 mm while the mid-lingual was 1.05 ±0.43 mm (P = 0.008). Interestingly, prostheses with mid-buccal EA>30∘ exhibited slightly lower VT, but higher HT, than the ones with EA≤30∘. Prostheses with proximal EA>30∘ displayed slightly more MBL, compared to prostheses with EA≤30∘. The mean KMW was 4.08 ±1.10 mm. Conclusions Free gingival grafting is a predictable treatment approach to augmenting soft tissue 3-dimensionally. Prostheses with EA≤30∘ were preferable for preserving the maximal VT and maintaining crestal bone stability. This article is protected by copyright. All rights reserved View on Web

The association of specific types of vegetables consumption with 10‐year type II diabetes risk: Findings from the ATTICA cohort study.

alexandrossfakianakis shared this article with you from Inoreader The association of specific types of vegetables consumption with 10‐year type II diabetes risk: Findings from the ATTICA cohort study. via Journal of Human Nutrition and Dietetics Abstract Background To investigate the association between vegetable consumption, in total as well as per type/ category, and 10-year type-2 diabetes mellitus (T2DM) incidence. Methodology ATTICA study was conducted during 2001-2012 in 3,042 apparently healthy adults living in Athens area, Greece. A detailed biochemical, clinical, and lifestyle evaluation was performed; vegetables' consumption (total, per type) was evaluated through a validated semi-quantitative food frequency questionnaire. After excluding those with no complete information of diabetes status or those lost at the 10-year follow-up, data from 1,485 participants were used for the current analysis. Results After adjusting for several participants' characteristics, including overall dietary habits, it was observed that participants consuming at least 4 servings/day of vegetables had 0.42-times lower risk of developing T2DM [HR (95% CI): 0.42 (0.29, 0.61)]; the benefits of consumption we re greater in women [HR (95% CI): 0.29 (0.16, 0.53)] as compared to men [HR (95% CI): 0.56 (0.34, 0.92)]. Only 33% of the sample consumed vegetables 4 servings/day. The most significant associations were observed for allium vegetables in women and for red/orange/yellow vegetables, as well as for legumes in men. Principal conclusions The intake of at least 4 servings/day of vegetables was associated with a considerably reduced risk of T2DM, independently of other dietary habits; underlying the need for further elaboration of current dietary recommendations at population level.

Prevalence of anti‐Parvovirus B19 IgG and IgM and Parvovirus B19 viremia in pregnant women in an urban area of northern Italy

alexandrossfakianakis shared this article with you from Inoreader Prevalence of anti‐Parvovirus B19 IgG and IgM and Parvovirus B19 viremia in pregnant women in an urban area of northern Italy via Journal of Medical Virology Abstract Parvovirus B19 (B19V) infection in pregnancy is mostly asymptomatic, but can cause complications including abortion and foetal hydrops. Although its infection is ubiquitous, seroprevalence among pregnant women varies according to different geographical areas. Since seroprevalence data in Italy are limited, the prevalence of antibodies and DNA in pregnant women was evaluated retrospectively, correlating the clinical situation of mothers and newborns. One thousand eight hundred and ninety-three sequential sera were examined from pregnant women (60.8% in the first trimester, 16.6% in the second one and 22.6% in the third one, respectively) for anti-B19V IgG and IgM (confirmed by immunoblot); 1402 (74.1%) were of Italian origin and 491 (25.9%) non-Italian women. Molecular tests were used to search for viral genome. One thousand three hundred and fifteen (69.5%) samples were IgG-positive, 21 (1.1%) IgM-positive for and 578 (30.5%) non-immune. The difference in Ig G seroprevalence between Italian (71.1%) and non-Italian women (64.8%) was statistically significant. Of the 21 IgM-positive women, 16 were confirmed positive also by immunoblot (prevalence: 0.8%), of which 11 were viraemic (prevalence: 0.6%; mean 1.3x104 geq/mL). Mothers were asymptomatic, and the newborns had no clinical signs of congenital infection. IgG seroprevalence in Italy is high, with differences between Italian women and non-Italian women from geographic areas with lower endemic levels of B19V. The consistent migratory flows in place could lead to an increase in the number of susceptible women. The prevalence of viremia is low, and has not been associated with evident foetal damage at birth. This article is protected by copyright. All rights reserved. View on Web

SARS‐CoV‐2 ORF10 antagonizes STING‐dependent interferon activation and autophagy

alexandrossfakianakis shared this article with you from Inoreader SARS‐CoV‐2 ORF10 antagonizes STING‐dependent interferon activation and autophagy via Journal of Medical Virology Abstract A characteristic feature of COVID-19, the disease caused by SARS-CoV-2 infection, is the dysregulated immune response with impaired type I and III interferon (IFN) expression and an overwhelming inflammatory cytokine storm. RIG-I-like receptors (RLRs) and cGAS-STING signaling pathways are responsible for sensing viral infection and inducing IFN production to combat invading viruses. Multiple proteins of SARS-CoV-2 have been reported to modulate the RLR signaling pathways to achieve immune evasion. Although SARS-CoV-2 infection also activates the cGAS-STING signaling by stimulating micronuclei formation during the process of syncytia, whether SARS-CoV-2 modulates the cGAS-STING pathway requires further investigation. Here, we screened 29 SARS-CoV-2-encoded viral proteins to explore the viral proteins that affect the cGAS-STING signaling pathway and found that SARS-CoV-2 ORF10 targets STING to antagonize IFN activation. Overexpression of ORF10 inhibits cGAS-ST ING-induced IRF3 phosphorylation, translocation, and subsequent IFN induction. Mechanistically, ORF10 interacts with STING, attenuates the STING-TBK1 association, and impairs STING oligomerization and aggregation and STING-mediated autophagy; ORF10 also prevents the endoplasmic reticulum (ER)-to-Golgi trafficking of STING by anchoring STING in the ER. Taken together, these findings suggest that SARS-CoV-2 ORF10 impairs the cGAS-STING signaling by blocking the translocation of STING and the interaction between STING and TBK1 to antagonize innate antiviral immunity.

Hypothyroidism After Using Superior Thyroid Artery as A Recipient Artery

alexandrossfakianakis shared this article with you from Inoreader Hypothyroidism After Using Superior Thyroid Artery as A Recipient Artery via The Laryngoscope The aim of this study was to evaluate whether the use of the superior thyroid artery (SThA) as a recipient vessel affect thyroid dysfunction in patients undergoing TPLE combined with hemithyroidectomy. Our study revealed there was no significant difference in the postoperative hypothyroidism between patients with SThA used and not. We suggest that even after hemithyroidectomy, with inferior thyroid arteries are preserved, the SThA can be used as a recipient vessel. Objective Superior thyroid artery (SThA) is a common recipient artery in free tissue transfer even after total pharyngolaryngoesophagectomy (TPLE) with hemithyroidectomy. The aim of this study was to evaluate whether the use of SThA as a recipient vessel affect thyroid function in patients undergoing TPLE with hemithyroidectomy. Methods From 2011 to 2020, 91 patients who underwent free jejunum transfer after TPLE with hemithyroidectomy were divided into two groups. In Group1 (n = 47), the contralateral SThA was used for the anastomosis. In Group2 (n = 44), other vessels were used. Retrospective chart review was performed comparing postoperative thyroid function between two groups. Results In group1, 17 patients presented hypothyroidism, 21 presented latent hypothyroidism and 9 presented no thyroid dysfunction comparing 15, 19, and 10 respectively in group 2. There were no significant differences between the two groups. Conclusion Even after hemithyroidectomy, with inferior thyroid arteries are preserved, the SThA can be used as a recipient vessel.

Magnetic Targeting of Gadolinium Contrast to Enhance MRI of the Inner Ear in Endolymphatic Hydrops

alexandrossfakianakis shared this article with you from Inoreader Magnetic Targeting of Gadolinium Contrast to Enhance MRI of the Inner Ear in Endolymphatic Hydrops via The Laryngoscope This is the first study to magnetically target gadolinium contrast to the inner ear as an effective, minimally-invasive, local delivery technique that can be tracked by magnetic resonance imaging (MRI). Better accumulation of gadolinium contrast allows better visualization and quantification of endolymphatic hydrops. Objectives 1. Determine the feasibility and efficiency of local magnetic targeting delivery of gadolinium (Gad) contrast to the inner ear in rodents. 2. Assess any potential ototoxicity of magnetic targeting delivery of Gad in the inner ear. 3. Study the utility of magnetic targeting delivery of Gad to visualize and quantify endolymphatic hydrops (EH) in a transgenic mouse model. Study Design Controlled in vivo animal model study. Methods Paramagnetic Gad was locally delivered to the inner ear using the magnetic targeting technique in both rat and mouse models. Efficiency of contrast delivery was assessed using magnetic resonance imaging (MRI). Ototoxicity of Gad was examined with histology of the cochlea and functional audiological tests. The Phex mouse model was used to study EH, hearing loss, and balance dysfunction. Magnetic targeting delivery of Gad contrast was used in the Phex mouse model to visualize the effects of EH using MRI. Results Magnetic targeting improved the delivery of Gad to the inner ear and the technique was reproducible in both rat and mouse models. The delivery method did not result in microstructural damage or any significant hearing loss in a normal animal. Magnetic targeting of Gad in the Phex mouse model allowed detailed visualization and quantification of EH. Conclusion This study provided the first evidence of the effectiveness and efficiency of the local magnetic targeting delivery of gadolinium contrast to the inner ear and its application to the visualization and quantification of EH.

Endonasal access to the lateral poststyloid space: Far lateral extension of an endoscopic endonasal corridor

alexandrossfakianakis shared this article with you from Inoreader Endonasal access to the lateral poststyloid space: Far lateral extension of an endoscopic endonasal corridor via Head & Neck Abstract The styloid process constitutes the posterolateral boundary for an endonasal exposure of the infratemporal fossa. This study aims to explore the feasibility of a far-lateral extension to the lateral poststyloid space via an endonasal corridor. An endonasal dissection was performed on six cadaveric specimens (12 sides). Following an endoscopic endonasal access to the parapharyngeal space, the styloid process and the tympanic portion of the temporal bone were removed to reveal the jugular bulb and the extratemporal facial nerve. Distances from the anterior nasal spine to the relevant landmarks were measured using a surgical navigation device. Through an endonasal corridor, only the anteroinferior aspect of the jugular bulb was exposed. Conversely, the extratemporal facial nerve could be sufficiently exposed, and the deep temporal nerve could be transposed to the stylomastoid foramen. The average horizontal distances from the nasal spine to the posterior tract of V3, stylo id process, and facial nerve were 79.33 ± 3.41, 97.10 ± 4.74, and 104.77 ± 4.42 mm, respectively. Access to the lateral poststyloid space via an endonasal corridor is feasible, potentially providing an alternative approach to address select lesions extending to this region. The deep temporal nerve has a similar diameter to that of the facial nerve; thus, providing potential reinnervation of the facial nerve. View on Web
