Chest CT screening for COVID-19 in elective and emergency surgical patients: experience from a UK tertiary centre. Clin Radiol 2020; 75:599-605. [PMID: 32593409 PMCID: PMC7301066 DOI: 10.1016/j.crad.2020.06.006] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Accepted: 06/11/2020] [Indexed: 12/22/2022]
Abstract
AIM To determine the incidence of possible COVID-19-related lung changes on preoperative screening computed tomography (CT) for COVID-19 and how their findings influenced decision-making. To also to determine whether the patients were managed as COVID-19 patients after their imaging findings, and the proportion who had SARS-CoV2 reverse transcriptionpolymerase chain reaction (RT-PCR) testing. MATERIALS AND METHODS A retrospective study was undertaken of consecutive patients having imaging prior to urgent elective surgery (n=156) or acute abdominal imaging (n=283). Lung findings were categorised according to the British Society of Thoracic Imaging (BSTI) guidelines. RT-PCR testing, management, and outcomes were determined from the electronic patient records. RESULTS 3% (13/439) of CT examinations demonstrated findings of classic/probable COVID-19 pneumonia, whilst 4% (19/439) had findings indeterminate for COVID-19. Of the total cohort, 1.6% (7/439) subsequently had confirmed RT-PCR-positive COVID-19. Importantly, all the patients with a normal chest or alternative diagnoses on CT who had PCR testing within the next 7 days, had a negative RT-PCR (92/407). There was a change in surgical outcome in 6% (10/156) of the elective surgical cohort with no change to surgical management was demonstrated in the acute abdominal emergency cohort requiring surgery (2/283). CONCLUSION There was a 7% (32/439) incidence of potential COVID-19-related lung changes in patients having preoperative CT. Although this altered surgical management in the elective surgical cohort, no change to surgical management was demonstrated in the acute abdominal emergency cohort requiring surgery.

Abstract
AIM To compare the interobserver reliability and diagnostic accuracy of the British Thoracic Society (BTS) scale and other visual assessment criteria in the context of 2-[18F]-fluoro-2-deoxy-d-glucose (FDG) positron-emission tomography (PET)-computed tomography (CT) evaluation of solid pulmonary nodules (SPNs). MATERIALS AND METHODS Fifty patients who underwent FDG PET-CT for assessment of a SPN were identified. Seven reporters with varied experience at four centres graded FDG uptake visually using the British Thoracic Society (BTS) four-point scale. Five reporters also scored SPNs according to three- and five-point visual assessment scales and using semi-quantitative assessment (maximum standardised uptake value [SUVmax]). Interobserver reliability was assessed with the intra-class correlation coefficient (ICC) and weighted Cohen's kappa (κ). Diagnostic performance was evaluated by receiver operator characteristic (ROC) analysis. RESULTS Good interobserver reliability was demonstrated with the BTS scale (ICC=0.78, 95% confidence interval [CI]: 0.69-0.85) and five-point scale (ICC=0.78, 95 CI 0.68-0.86), whilst the three-point scale demonstrated moderate reliability (ICC=0.70, 95% CI: 0.59-0.80). Almost perfect agreement was achieved between two consultants (κ=0.85), and substantial agreement between two other consultants (κ=0.78) using the BTS scale. ROC curves for the BTS and five-point scales demonstrated equivalent accuracy (BTS area under the ROC curve [AUC]=0.768; five-point AUC=0.768). SUVmax was no more accurate compared to the BTS scale (SUVmax AUC=0.794; BTS AUC=0.768, p=0.43). CONCLUSIONS The BTS scale can be applied reliably by reporters with varied levels of PET-CT reporting experience, across different centres and has a diagnostic performance that is not surpassed by alternative scales.

Abstract
This study was conducted to evaluate the effects of iron glycine chelate (Fe-Gly) on egg quality of laying hens. A total of 810 laying hens (HyLine Variety White, 26 wk old) were randomly assigned to 6 groups, and each group consisting of 135 hens (5 replicates of 27 hens each). Hens in the control group received a diet supplemented with 60 mg Fe/kg as FeSO4, whereas hens in the other 5 groups received diets supplemented with 0, 20, 40, 60, and 80 mg Fe/kg from Fe-Gly, respectively. The study showed that dietary Fe-Gly treatments influenced (P < 0.05) the internal egg quality (egg weight, Haugh unit, albumen height), compared with the control group. However, dietary Fe-Gly supplementation showed few effects on the ultrastructure of eggshell in this study. The group of 60 mg Fe/kg as Fe-Gly was promoted (P < 0.05) in succinate dehydrogenase levels of liver and spleen compared with the 0 mg Fe-Gly/kg group, whereas the control (Fe/kg as FeSO4) group has no differences compared with the 0 mg Fe-Gly/kg group. The concentrations of Fe in the eggshell, yolk, and albumen were increased with increasing concentrations of Fe-Gly, where Fe-Gly (60, 80 mg Fe/kg) had higher (P < 0.01) Fe concentration than the control in yolk and albumen. The Fe-Gly groups (60, 80 mg Fe/kg) were influenced (P < 0.05) in transferrin, divalent mental transport 1, and ferroportin 1, compared with the control (FeSO4). In conclusion, Fe-Gly (60 mg Fe/kg) improved egg quality and egg iron enrichment. In general, there were no significant differences between Fe-Gly (40) and the control group in albumen height, Haugh unit, Fe concentration in eggshell and yolk. It revealed that FeSO4 could be substituted by a lower concentration of Fe-Gly and Fe-Gly may be superior to FeSO4 for egg quality in laying hens.

Abstract
The clinical outcome of oral squamous cell carcinoma (OSCC) has not improved in recent years, mainly due to the limited effective targeted therapy that has been applied. Recently, a transcriptional coactivator, YAP, has been shown to have a key regulatory role in malignant progression in multiple cancers, including OSCC. But pharmacologically targeting YAP or the Hippo pathway, which is the main signaling pathway regulating YAP, has been proven to be challenging. Therefore, uncovering YAP upstream regulators in cancer would identify novel therapeutic targets for treatment of YAP-sustained cancers. Here, we showed that YAP was overactivated in OSCC and that high YAP activity in patients with OSCC was associated with malignant progression and poor survival. We uncovered that GPR39 (a G protein-coupled receptor) was overexpressed in OSCC, that the expression level of GPR39 was correlated with the activity level of YAP, and that the high GPR39 expression was associated with malignant progression and poor survival in patients with OSCC. Moreover, we found that GPR39 regulated YAP through a Gαq/11-RhoA-dependent signaling pathway. Importantly, inhibition of GPR39 resulted in YAP-sustained OSCC growth inhibition. Our findings suggest that GPR39 is a potential therapeutic target for OSCC treatment with itself as a biomarker.

Abstract
Objective: To investigate the goal-oriented retroperitoneoscopic adrenalectomy and report the initial experiment. Methods: A total of 102 patients were selected to our clinic experiment, and performed retroperitoneoscopic adrenalectomy with the new method. including adrenal cortex adenoma 76 cases, phaochromocytoma 12 cases, adrenal cyst 6 cases, myelolipoma 4 cases, gangliocytoma 1 case and corticohyperplassia 3 cases. The mean diameter of the tumors was 2.8 cm (0.5-5.8 cm). The operative procedure was briefly described as such, with ultrasound guiding, a needle was punched percutaneously up to the adrenal mass or the renal upper pole from lateral to posterior axillary line just below the inferior border of the 12th rib. labeled the pathway of the needle with methylene blue. Along the way of the needle, a 12 mm port was introduced into the retroperitoneal space with closed method, and the laparoscope with a working tunnel was introduced to make a tunnel along the label up to the adrenal for finally removing it. Additional port should be used when it was needed in the procedure. Results: The procedures of all patients were successful, and 10 patients were performed with only one port, 81 patients with two ports, 11 patients with three ports. The operative duration was 49 (31-115) min, the average blood loss was 38 (0-260) ml. There was no transition to open surgery and no perioperative complications. The length of postoperative hospital stay was 4.1 d (2-7 d). 98 patients were available for follow-up of 16.5 months (1-38 months), no complication was found. Conclusions: The new method of retroperitoneoscopic adrenalectomy is feasible and safe for renal masses, and compared to the conventional method, it may be less trauma to the abdominal wall and retropertoneal tissue, and it was also better on cosmetics.

Abstract
OBJECTIVE To investigate the connection between atrial fibrillation (AF) and miR-138-5p and to further explore the possible mechanism. PATIENTS AND METHODS MiR-138-5p expression of right atrial appendage (RAA) tissues in 28 patients with AF and 22 patients with sinus rhythm (SR) was detected by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). Moreover, cell proliferation assay was conducted in AC16 cells which were transfected by miR-138-5p inhibitors or mimics. Furthermore, Western blot assay, luciferase assay, and RNA immunoprecipitation assay were performed to uncover the mechanism. RESULTS In the present research, miR-138-5p expression in RAA samples decreased significantly in AF patients than that in SR ones. Moreover, in AC16 cells, higher miR-138-5p expression level suppressed cell growth, while cell growth was promoted after miR-138-5p was knockdown. In addition, further experiments showed that CYP11B2 acted as the main target of miR-138-5p and its expression in AF tissues negatively correlated to miR-138-5p expression. CONCLUSIONS All the results above elucidated that cell proliferation of AF could be inhibited by miR-138-5p via suppressing CYP11B2, which may offer a new vision for interpreting the mechanism of AF development.

Abstract
Fecal calprotectin has successfully been widely recommended as a sensitive biomarker of inflammatory bowel diseases (IBD). Recently, we have identified an excellent new fecal biomarker, B cell activating factor (BAFF), as being as effective as fecal calprotectin for diagnosing intestinal inflammation. In this study, a total of 230 patients with abdominal discomfort were prospectively enrolled and fecal samples were collected within 24 h before the endoscopic examinations. We show that fecal BAFF levels were significantly higher in patients with ulcerative colitis (median = 1549 pg/g, P < 0·0001), Crohn's disease (median = 735 pg/g, P < 0·0001), gastric cancer (median = 267 pg/g, P < 0·0001) and colorectal cancer (median = 533 pg/g, P < 0·0001) than those in healthy groups (median = 61 pg/g), while the values of which in patients with gastric polyps, colorectal polyps, esophagitis/gastritis/duodenitis and peptic ulcer were in the range of healthy individuals (P > 0·05). An optimal cut-off value at 219·5 pg/g of fecal BAFF produced sensitivity, specificity, positive predictive and negative predictive values of 85, 91, 84 and 92%, respectively, for IBD or carcinoma. Our results therefore indicate a potential role for fecal BAFF as a sensitive screening parameter for IBD and gastrointestinal carcinoma, as well a useful tool to select patients with abdominal discomfort for further endoscopic examinations.

Abstract
METHODS We conducted a study of per- and polyfluoroalkyl substance biomarkers, including PFOA, in girls from Greater Cincinnati (CIN, N = 353) and the San Francisco Bay Area (SFBA, N = 351). PFOA was measured in the baseline serum sample collected in 2004-2007 of 704 girls at age 6-8 years. Mixed effects models were used to derive the effect of PFOA on BMI, waist-to-height and waist-to-hip ratios over increasing age in this longitudinal cohort. RESULTS Median PFOA serum concentrations were 7.3 (CIN) and 5.8 (SFBA) ng/mL, above the U.S. population median for children 12-19 years in 2005-2006 (3.8 ng/mL). Log-transformed serum PFOA had a strong inverse association with BMIz in the CIN girls (p = 0.0002) and the combined two-site data (p = 0.0008); the joint inverse effect of PFOA and Age*PFOA weakened at age at 10-11 years. However, in the SFBA group alone, the relationship was not significant (p = 0.1641) with no evidence of changing effect with age. The effect of PFOA on waist:height ratio was similar to BMIz at both sites, but we did not find a significant effect of PFOA on waist:hip ratio in either the CIN or SFBA girls. CONCLUSIONS PFOA is associated with decreased BMI and waist:height ratio in young girls, but the strength of the relationship decreases with age. Site heterogeneity may be due to greater early life exposure in Cincinnati.

Abstract
This study hypothesizes that in ovo sulfur amino acids (SAA) injection can alleviate the heat or oxidative stress of hatched chicks. Thus, the study aimed to assess the impact of in ovo injection of SAA with heat stress during the incubation on heat shock protein 70 (HSP70), corticosterone hormone, antioxidant indices, and lipid profile of newly hatched broiler chicks. Eggs were incubated under optimal incubation temperature (37.8°C) from days 1 to 10 then under high temperature (39.6°C for 6 h daily) between 10 and 18 D of the incubation. At day 17.5 of incubation, 150 eggs were randomly divided into 3 groups of 50 replicate eggs. The first group served as control (non-injected group, NIG), the second group was only injected with saline solution (saline-injected group, SIG), and the third group was injected with a mixture of 5.90 mg L-methionine plus 3.40 mg L-cysteine (sulfur amino acids-injected group, SAAIG). The results exhibited that serum HSP70 and corticosterone concentrations were significantly reduced (P < 0.001) in the SAAIG compared with the NIG and SIG. In ovo SAA injection significantly augmented the antioxidant indices in the serum and tissues compared with the NIG and SIG. HSP70 mRNA relative expression was decreased but glutathione peroxidase (GSH-Px) mRNA relative expression was augmented in the tested tissues (P < 0.001) in the SAAIG compared with the NIG. The SAAIG had significantly (P < 0.05) lower levels in serum lipid profile compared to those of the control and SIG. In conclusion, in ovo SAA injection (methionine plus cysteine) in the embryonated eggs exposed to heat stress increased GSH-Px gene expression and antioxidant indices, and reduced HSP70 gene expression, corticosterone concentrations, and lipid profile of newly hatched broiler chicks.

Abstract
BACKGROUND We conducted a single-arm phase II trial to evaluate the efficacy and adverse effects (AEs) of an anti-epidermal growth factor receptor monoclonal antibody, nimotuzumab, combined with cisplatin and 5-fluorouracil (PF) as first-line treatment in recurrent metastatic nasopharyngeal carcinoma after radical radiotherapy. METHODS Patients who met the eligibility criteria were recruited from ten institutions (ClinicalTrials.gov; NCT01616849). A Simon optimal two-stage design was used to calculate the sample size. All patients received weekly nimotuzumab (200 mg) added to cisplatin (100 mg/m2 D1) and 5-fluorouracil (4 g/m2 continuous infusion D1-4) every 3-weekly for a maximum of six cycles. Primary end point was objective response rate (ORR). Secondary end points included disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and AEs. RESULTS A total of 35 patients were enrolled (13 in stage 1 and 22 in stage 2). Overall ORR and DCR were 71.4% (25/35) and 85.7% (30/35), respectively. Median PFS and OS were 7.0 (95% CI 5.8-8.2) months and 16.3 (95% CI 11.4-21.3) months, respectively. Unplanned exploratory analyses suggest that patients who received ≥2400 mg nimotuzumab and ≥4 cycles of PF had superior ORR, PFS and OS than those who did not (88.9% versus 12.5%, P < 0.001; 7.4 versus 2.7 months, P = 0.081; 17.0 versus 8.0 months, P = 0.202). Favourable subgroups included patients with lung metastasis [HROS 0.324 (95% CI 0.146-0.717), P = 0.008] and disease-free interval of >12 months [HROS 0.307 (95% CI 0.131-0.724), P = 0.004], but no difference was observed for metastatic burden. The only major grade 3/4 AE was leukopenia (62.9%). CONCLUSION Combination nimotuzumab-PF chemotherapy demonstrates potential efficacy, and is well tolerated as first-line chemotherapy regimen in recurrent metastatic nasopharyngeal carcinoma.

Abstract
Objective: To construct the mmu-miR-155 eukaryotic overexpression vector pmR-155 and to investigate its effect on HBV replication and expression of PTEN in vivo. Methods: The mmu-mir-146a precursor gene fragment pre-mmu-mir-146a was amplified by PCR, then connected to the pmR-mCherry plasmid vector after double enzyme digestion, the accuracy of recombinant vector was verified by colony PCR、double enzyme digestion and sequencing; then the recombinant vector was transfected HBV transgene mice(Experimental Group)with hydrodynamics-based injection via vena caudalis, and pmR-mCherry plasmid、PBS were respectively transfected into the mice as Empty plasmid Group、Blank Group. The concentration of IFN-γ in the serum was detected by ELISA. The expression of SOCS1、PTEN mRNA in the liver was detected by qPCR at 30d post-transfectioned. The Western blot was performed to detect the changes in SOCS1、PTEN、HBX in the liver tissue at 30 d post-transfectioned. The results were analyzed with Student's t-test, or one-way analysis of variance and the least significant difference test. Results: the colony PCR、double enzyme digestion and sequencing verified that the gene was inserted into the pmR-mCherry vector. Compared with Blank Group, the expression of miR-155 in the Experimental Group was significantly increased(t = 8.90, P < 0.01); the concentration of IFN-γ in the Experimental Group was significantly increased(F = 26.58, P < 0.01); the mRNA(F(SOCS1 mRNA) = 19.72, P < 0.01; F(PTEN mRNA) = 7.38, P < 0.05) and protein(F(SOCS1) = 50.30, P < 0.01; F(PTEN) = 129.00, P < 0.01) expression of COCS1、PTEN was significantly decreased in the Experimental group and the protein of HBX was also significantly(F(HBX) = 77.97, P < 0.01). Conclusion: The pmR-155 eukaryotic overexpression vector is successfully constructed, this recombinant vector can express miR-155 stably; miR-155 can down-regulate cocs1、PTEN gene expression and up-regulate the expression of IFN-γ, it can inhibit the replication of HBV and a potential targets to treating hepatocellular carcinoma.
