Predictive Value of Risk Factors for Pharyngocutaneous Fistula After Total Laryngectomy

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

Feasibility of robotic thyroidectomy via hairline incision using da Vinci single port system: Initial experience with 40 consecutive cases

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background

This study aimed to introduce our robotic technique, which can minimize dissection extent using the da Vinci SP robotic system via hairline incision.

Methods

Forty patients underwent robotic thyroidectomy using the da Vinci SP robotic system via a hairline incision between February 2020 and April 2021 at Ulsan University Hospital. All procedures were performed successfully by one surgeon using the SP robotic system.

Results

Hemithyroidectomies were performed in 32 patients and total thyroidectomies in eight patients. Central neck dissection was performed in 32 patients. The overall mean operative time was 140.2 ± 50.7 min, and the mean console time was 74.0 ± 42.7 min. All patients were discharged on the second or third day after operation without any complications.

Conclusions

Robotic thyroidectomy using the SP robotic system via hairline incision is technically feasible and safe, with a shorter incision length when compared with that of the Xi system.

Effects of baloxavir and oseltamivir antiviral therapy on the transmission of seasonal influenza in China: a mathematical modeling analysis

alexandrossfakianakis shared this article with you from Inoreader

Abstract

New antiviral influenza treatments can effectively alleviate illness while reducing viral shedding. However, how such effects can translate into lower population infections of seasonal influenza in China remains unknown. To shed light on the public health impacts of novel antiviral agents for influenza, we constructed a dynamic transmission model to simulate the seasonal influenza epidemics in China. Two antivirus treatments, baloxavir and oseltamivir, were evaluated by estimating their impacts on the incidences of influenza infection in a single flu season. In the base-case analysis of 10% antiviral treatment uptake rate, 2,760 and 3,420 per 10,000 persons contracted influenza under the treatment of baloxavir and oseltamivir, respectively. These incidence rates amounted to a 18.90% relative risk reduction (RRR) of infection associated with baloxavir in relation to oseltamivir. The corresponding RRR was 82.16% when the antiviral treatment uptake rate was inc reased to 35%. In addition, the peak of the prevlance of infected individuals (per 10,000 persons) under the baloxavir treatment was 177 (Range: 93 to 274) fewer than that of oseltamivir. Our analyses suggest that the baloxavir treatment strategy reduces the incidence of influenza in China compared with oseltamivir in the setting of a seasonal flu epidemic. Also, increasing the uptake rate of antiviral treatment can potentially prevent millions of infections during a single flu season.

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

alexandrossfakianakis shared this article with you from Inoreader

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.

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

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.
