The pathological classification of well-differentiated pancreatic neuroendocrine tumour (pNET) is based largely upon Ki-67 index. However, current controversies abound about the classification of pNETG1/pNETG2.

Clinicopathological data were retrospectively analysed for 153 pNETG1/pNETG2 patients hospitalized at China-Japan Friendship Hospital. The critical values of pNETG1/pNETG2 were examined by using the area under the receiver operating characteristic curve and survival analysis was used to compare the clinical prognosis of pNETG1/G2.

Among them, 52.3% were males. The median age was 49 (18-81) years and the clinical types were pNETG1 (n=38) and pNETG2 (n=115). According to the receiver operating characteristic curve, the optimal cut-off value was 5.5% for classifying pNETG1/pNETG2. Significant differences between pNETG1 (n=101) and pNETG2 (n=52) existed in overall survival (P=0.001) and disease-free survival (P=0.013) when Ki-67 index was 5%. Yet no significant differences existed in overall survival (P=0.378) or disease-free survival (P=0.091) between pNETG1 and pNETG2 when Ki-67 index was 3%. Furthermore, multivariate analysis indicated that the revised pathological grade was an independent risk factor for mortality and post-operative recurrence of pNET patients (P=0.003 and 0.014; hazard ratio (HR) =4.005 and 2.553).

Thus, differentiating pNETG1/pNETG2 with Ki-67 index (5%) is proposed as the cut-off value and a new Ki-67 index (5%) is a better predictor of pNET mortality and post-operative recurrence than Ki-67 index (3%).

Here, we show that the expression of Capn4 was significantly increased in Angiotensin II (Ang II)-treated cardiomyocytes and Ang II-induced cardiac hypertrophic mouse hearts. Importantly, in agreement with the Capn4 expression patterns, the maximal calpain activity measured in heart homogenates was elevated in Ang II-treated mice, and oral coadministration of SNJ-1945 (calpain inhibitor) attenuated the total calpain activity measured in vitro. Functional assays indicated that overexpression of Capn4 obviously aggravated Ang II-induced cardiac hypertrophy, whereas Capn4 knockdown resulted in the opposite phenotypes. Further investigation demonstrated that Capn4 maintained the activation of the insulin-like growth factor (IGF)-AKT signaling pathway in cardiomyocytes by increasing c-Jun expression. Mechanistic investigations revealed that Capn4 directly bound and stabilized c-Jun, and knockdown of Capn4 increased the ubiquitination level of c-Jun in cardiomyocytes. Additionally, our results demonstrated that the antihypertrophic effect of Capn4 silencing was partially dependent on the inhibition of c-Jun. Overall, these data suggested that Capn4 contributes to cardiac hypertrophy by enhancing the c-Jun-mediated IGF-AKT signaling pathway and could be a potential therapeutic target for hypertrophic cardiomyopathy.

This study aimed to compare knowledge, attitude and practice (KAP) regarding COVID-19 between public health workers (PHWs) attended field epidemiology training program (FETP-trained) and those who did not attend FETP (non-FETP trained).

Multi-country cross-sectional survey was conducted among PHWs who participated in COVID-19 pandemic in 10 countries at EMR. Online questionnaire that included demographic information, KAP regarding COVID-19 pandemic was distributed among HCWs. Scoring system was used to quantify the answers, bivariate and Multivariate analysis performed to compare FETP-trained with non-FETP trained PHWs.

Overall, 1337 PHWs participated, with 835 (62.4%) < 40years of age, and 851 (63.6%) males. Of them, 423 (31.6%) had FETP, including that 189 (44.7%) had advanced level, 155 (36.6%) intermediate and 79 (18.7%) basic level training. Compared with non-FETP trained, FETP trained were older, having higher KAP scores. FETP participation was low in infection control, and PH laboratories. KAP mean scores for intermediate level attendees are comparable to advanced level.

FETP-trained are having better KAP than non-FETP PHWs. Expanding the intermediate level, maintain the Rapid Response training and introduce the laboratory component are recommended to maximize the benefit from FETP. Infection control, antimicrobial resistance and coordination are areas where training should include.

Optimal dose-fractionation regimen of stereotactic body radiotherapy for peripheral early-stage non-small cell lung cancer remains unclear. We retrospectively investigated outcomes of stereotactic body radiotherapy using CyberKnife at 54Gy in three fractions in 26 patients (median age 76years) with pathologically confirmed T1b-T2aN0M0 non-small cell lung cancer.

A 54Gy in three fractions was prescribed to cover the 99% of gross tumor volume. We estimated cumulative local control, progression-free survival and overall survival rates (Kaplan-Meier method), and toxicity (Common Toxicity Criteria for Adverse Events, version 5.0).

All the tumors were located at peripheral area of lung. Mean distance from chest wall to tumor was 6.5mm (range 0-32mm). The patients' pathological diagnoses were adenocarcinoma n=18, squamous cell carcinoma n=7 and non-small cell carcinoma n=1. Their stages were T1b n=9, T1c n=14 and T2a n=3. Median follow-up was 24months (range 6-54). Cumulative 2-year effect rates were local control 100%, progression-free survival 70% and overall survival 92%. Twenty patients developed grade one radiation pneumonitis, but grade 2 or greater radiation pneumonitis was not observed.

We found CyberKnife-stereotactic body radiotherapy for pathologically confirmed T1b-T2aN0M0 non-small cell lung cancer to be effective and safe. However, these results should be validated with a larger patient cohort and prospective follow-up monitoring.

A suboptimal maternal vaccination coverage in 2017-18 has been reported in Italy. The study aims were to (i) assess changes in maternal influenza and tetanus, diphtheria and acellular pertussis vaccination coverage during 2018-19 influenza season compared to the previous season (ii) estimate influenza vaccine coverage among maternal care providers (MCPs) and (iii) explore the characteristics of vaccine delivery to pregnant women.

We conducted a cross-sectional survey among pregnant women and MCPs about influenza and pertussis immunization during pregnancy. We also collected information regarding prenatal care characteristics and vaccine delivery among four centers in Italy.

We recruited 483 pregnant women and 452 MCPs. The influenza and pertussis vaccine uptake among pregnant women for the season 2018-19 was 14.9% and 60.9%, respectively. MCPs' influenza vaccine uptake was 33.6%. Knowing that the flu vaccine was safe for mothers and their infants and being vaccinated in the previous influenza season were associated with higher vaccine uptake. Regarding pertussis, being a housewife was associated to lower vaccine uptake, while knowing the vaccine is effective and safe for mothers and newborns were associated with higher pertussis vaccine uptake. Selleckchem Epigenetic inhibitor The single most important factor associated to higher coverage of both influenza and pertussis vaccines was receiving a health-care provider's vaccine advice. Most pregnant women (69.4%) stated that they preferred to be vaccinated in their same prenatal care setting.

Receiving a health-care provider's vaccine advice and the availability of vaccines during prenatal care visits might improve vaccination coverage among pregnant women.

We evaluated molecular alterations in MA to characterize its biology and pathogenesis. We searched a comprehensive institutional database for patients with MA treated between 2004 and 2019. Demographic, clinical, surgical, and radiographical data were collected. MA and associated meningioma tissues were evaluated using a next-generation sequencing assay interrogating 1425 cancer-related genes. We studied 5 cases 3 with MA and 2 with MA associated with a meningioma. Of the MAs associated with a meningioma, 1 had deletions in the NF2 gene in both the MA and the meningioma components, whereas the other had an NF2 deletion in only the MA component. Additional mutations were identified in the MA components, suggesting that MA arises from the meningioma rather than the meningioma resulting from a transformation of the MA. The 3 cases of pure MA showed variants of unknown significance with no alterations in known oncogenic drivers. Our findings provide a starting point to a better understanding of the pathogenesis of this rare lesion. Our study indicates that MA-meningiomas have a neoplastic nature that differs from the hamartomatous/developmental nature of pure MA.

Increasing the efficiency of early diagnosis using noninvasive biomarkers is crucial for enhancing the survival rate of lung cancer patients. We explore the differential expression of non-small cell lung cancer (NSCLC)-related long noncoding RNAs (lncRNAs) in urinary exosomes in NSCLC patients and normal controls to diagnose lung cancer.

A differential expression analysis between NSCLC patients and healthy controls was performed using microarrays. Gene ontology (GO) term and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were used to predict potential functions of lncRNAs in NSCLC. quantitative real-time PCR (QT-PCR) was used to verify microarray results.

A total of 640 lncRNAs (70 up- and 570 down-regulated) were differentially expressed in NSCLC patients in comparison to healthy controls. Six lncRNAs were detected by QT-PCR. GO term and KEGG pathway analyses showed that differential lncRNAs were enriched in cellular component organization or biogenesis, as well as other biological processes and signaling pathways, such as the PI3K-AKT, FOXO, p53, and fatty acid biosynthesis.

The differential lncRNAs in urinary exosomes are potential diagnostic biomarkers of NSCLC. The lncRNAs enriched in specific pathways may be associated with tumor cell proliferation, tumor cell apoptosis, and the cell cycle involved in the pathogenesis of NSCLC.
