Hoarseness is one of the classical symptoms in patients with locally advanced thoracic esophageal squamous cell carcinoma (ESCC), and it results from recurrent laryngeal nerve palsy, which is caused by nodal metastasis along the recurrent laryngeal nerve or by main tumors. We reviewed the short-term and long-term results of esophagectomy for patients with locally advanced ESCC and hoarseness at diagnosis.
Patients who initially presented with hoarseness from recurrent laryngeal nerve palsy between 2009 and 2018 and underwent esophagectomy for thoracic ESCC were eligible for this study. Pharyngolaryngectomy or cervical ESCC were exclusionary.
A total of 15 patients were eligible, and 14 underwent resection of the recurrent laryngeal nerves. The remaining patient had nerve-sparing surgery. Nine patients (60%) had post-operative complications ≥ Clavien-Dindo class II and, pulmonary complications were most common. Two patients (13%) died in the hospital. The 5-year overall survival rate for all patients was 16%. Age (≤ 65years), cT1/T2 tumor, and remarkably good response to neoadjuvant treatment were likely related to longer survival; however, these relationships were not statistically significant.
Esophagectomy for ESCC patients who are diagnosed with recurrent laryngeal nerve paralysis at initial presentation could be a treatment option if the patient is relatively young, has a cT1/T2 tumor, or shows a remarkably good response to neoadjuvant treatment. However, clinicians should be aware of the possibility of postoperative pulmonary complications, which were frequently observed with the procedure.

This study aimed to assess whether surgical case volume for lateral neck dissection has an impact on the survival of patients who have well-differentiated thyroid cancer (WDTC) with lateral cervical node metastases. The authors used a population-based cohort study design.
The study cohort consisted of WDTC patients in Ontario Canada who underwent thyroidectomy and lateral neck dissection. These patients were identified using both hospital- and surgeon-level administrative data between 1993 and 2017 (n = 1832). Surgeon and hospital volumes were calculated based on the number of cases managed in the year before the procedure by the physician and at the institution managing each case, respectively, and divided into tertiles. Multilevel Cox regression models were used to estimate the effect of volume on disease-free survival (DFS).
A crude model without patient or treatment characteristics demonstrated that DFS was associated with both higher surgeon volume tertiles (p < 0.01) and higher hospital volume tertiles (p < 0.01). After control for clustering, patient/treatment covariates, and hospital volume, the lowest surgeon volume tertile (range, 0-20/year; mean, 6.5/year) remained an independent statistically significant negative predictor of DFS (hazard ratio, 1.71; 95 % confidence interval, 1.22-2.4; p < 0.01).
Surgeon lateral neck dissection case volume is a predictor of better DFS for thyroid cancer patients, with the lowest surgeon volume tertile (<20 neck dissections per year) demonstrating poorer DFS.

Here we analyzed innovative problem-solving ability and performance enhancement through learning in the Olrog's Gull (Larus atlanticus), under controlled processes and experimental conditions. Trials were undertaken with nine adult individuals captured at a highly urbanized coastal area of Argentina. Each individual was presented with a Plexiglas box that could be opened by pushing or pulling two lids, each lid leading to a separated food reward. We measured problem-solving ability through consumption latency and the number of solved lids. As explanatory variables, we measured contact rate, as a measure of persistence, and the number of effective contacts. The results showed that the contact rate and effective contacts did not affect variables related to problem-solving ability during the first confrontation of the individuals with the closed box. Consumption latency decreased significantly throughout the trials, and with increasing contact rate and effective contacts. The number of solved lids increased through the trials independently of the contact rate and the total effective contacts with the box. Although persistence did not influence individuals' performance during the problem-solving test; this variable affected individuals' ability to solve the task throughout trials. Learning was evidenced by the decrease in the resolution time across experiments, suggesting that successful individuals improved their performance probably through a trial-and-error process. Evaluation of behavioral responses of a threatened seabird to a novel problem-solving task adds knowledge to previous field studies and provides a better understanding of the ability of individuals to adjust their foraging behavior in highly urbanized areas used during the non-breeding season.This study aimed to investigate the effects of incidence rate, heritability, and polygenic variance on the statistical power of genome-wide association studies (GWAS) for threshold traits. Different incidence rates of threshold trait (1, 3, 5, 10, 25, 40, 50, 60, 75 and 90%), heritability (10 and 25%), and polygenic variance ratio (0 and 25%) were simulated separately for common (MAF ≥ 0.05), low-frequency (0.05 > MAF ≥ 0.01), and rare (MAF  less then  0.01) variants. Association studies were performed by logistic and linear mixed models. The highest statistical powers were observed in common and low-frequency variants with an incidence of 25-50% and 10-40%, respectively, but for rare variants, the highest statistical power was observed at low incidence. For all causal variant frequencies, the estimated heritability decline with an increase in incidence rate. We found high statistical power for traits with high heritability. In contrast, those with a high polygenic variance ratio have lower statistical power to detect common causal variants using a linear mixed model. These results demonstrate that the incidence rate of threshold traits, heritability, and polygenic variance may affect the statistical power of GWAS. Therefore, it is recommended that the effect of incidence rate, heritability, and polygenic variance be considered in designing GWAS for threshold traits.
Hemorrhoidectomy is the standard procedure for treating high-grade hemorrhoids. However, postoperative pain usually causes patients to delay or refuse surgical treatment. Because maximal resting pressure in the internal anal sphincter plays a major role in post-hemorrhoidectomy pain, Botulinum toxin injections have been proposed to reduce it. However, the optimal timing of Botulinum toxin injections is still unclear. The aim of the present study was to compare the effectiveness of early and intraoperative Botulinum toxin injections for postoperative pain control.
In this pilot study, we enrolled patients who had grade III or IV hemorrhoids and underwent Ferguson hemorrhoidectomy at a single tertiary care center from October 1, 2018 to November 30, 2020. The experimental group received 50 U Botulinum toxin injections to the internal anal sphincter 1week before the operation, and the control group received injections intraoperatively. The primary endpoint was the daily maximal and resting visual analogue scerative days 1 (p = 0.024) and 4 (p = 0.044). Similar trends were observed on other days.
Early Botulinum toxin injection produced shorter hospital stays, and less reported pain after hemorrhoidectomy than intraoperative injections, especially for pain at rest.

Randomized controlled trials (RCTs) have reported that water exchange (WE) produced the highest adenoma detection rate (ADR) but did not evaluate right colon adenoma detection rate (rADR) as a primary outcome and only one of the trials employed blinded colonoscopists. The aim of our study was to determine whether, compared with air insufflation, WE significantly increases rADR and right colon serrated lesion detection rate (rSLDR) and decreases adenoma miss rate (rAMR).
This prospective, double-blind RCT was conducted at a regional hospital in Taiwan between December 2015 and February 2020. Standard WE and air insufflation were performed. After cecal intubation, the second blinded endoscopist examined the right colon and obtained rADR (primary outcome) and rSLDR. Then, the primary colonoscopist reinserted the scope to the cecum with WE in both groups and performed a tandem examination of the right colon to obtain rAMR.
There were 284 patients (50.9% male, mean age 58.9 ± 9.4years) who were randomized to WE (n = 144) or air insufflation (n = 140). The baseline characteristics were similar. The rADR (34.7% vs. 22.3%, p = 0.025), Boston Bowel Preparation Scale scores (mean, 2.6 ± 0.6vs. 2.2 ± 0.6, p < 0.001), rSLDR (18.1% vs. 7.1%, p = 0.007), and rAMR (31.5% vs. 45.2%, p = 0.038) were significantly different between WE and air insufflation.
The current study demonstrated a significantly higher rADR and rSLDR with the WE method performed by blinded colonoscopists. The impact of the significant findings in this report on the occurrence of interval cancers deserves to be studied.

Heavy metals are one of the important factors of environmental pollution. Heavy metals can cause adverse effects on the growth rate and the survival of herbivores, as well as immune function. In addition to heavy metals, another factor that insects are exposed to in nature is entomopathogens. The cellular and the antioxidant enzyme responses of insects are major bioindicators against the stressors. In this study, the differences in the hemocyte counts and the antioxidant enzyme activities of Hyphantria cunea larvae exposed to the different amounts of zinc, copper, and nickel and Bacillus thuringiensis infection were determined. With metal exposure, the superoxide dismutase, catalase, and glutathione peroxidase activities increased, but the hemocyte counts decreased. compound 3i nmr Additionally, both the hemocyte counts and the enzyme activities increased with Bacillus thuringiensis infection. Although heavy metal exposure decreased the hemocyte counts and increased the antioxidant enzyme activities, the increase in the hemocyte counts with bacterial infection and the increased antioxidant enzyme activities demonstrated that the response to infection in the insect was stronger and the synergistic effect was occurred.
