Final diagnoses included SPNs (n = 23) and non-functioning neuroendocrine tumours (n = 2). The overall accuracy of EUS-FNA was 80%. Tumour cells showed immunopositivity for β-catenin, CD10, CD99 and progesterone receptor (PR) in 93.7%, 87.5%, 83.3% and 66.6% of patients, respectively. No SPN showed immunopositivity for chromogranin A.

Intention-to-diagnose analysis showed that the diagnostic accuracy of EUS-FNA for SPNs using cell blocks and complementary IHC without cytological evaluation was fairly good. Evaluation of β-catenin, CD 10, CD99 and PR expression must be included in the IHC panel for diagnostic confirmation of SPNs using EUS-FNA biopsy specimens.

Pregnant women represent a potentially high-risk population in the COVID-19 pandemic.

To summarize clinical characteristics and outcomes among pregnant women hospitalized with COVID-19.

Relevant databases were searched up until May 29, 2020.

Case series/reports of hospitalized pregnant women with laboratory-confirmed COVID-19.

PRISMA guidelines were followed. Methodologic quality was assessed via NIH assessment tools.

Overall, 63 observational studies of 637 women (84.6% in third trimester) with laboratory-confirmed SARS-CoV-2 infection were included. Most (76.5%) women experienced mild disease. Maternal fatality, stillbirth, and neonatal fatality rates were 1.6%, 1.4%, and 1.0%, respectively. Older age, obesity, diabetes mellitus, and raised serum D-dimer and interleukin-6 were predictive of poor outcomes. Overall, 33.7% of live births were preterm, of which half were iatrogenic among women with mild COVID-19 and no complications. Most women underwent cesarean despite lacking a clear indication. Eight (2.0%) neonates had positive nasopharyngeal swabs after delivery and developed chest infection within 48hours.

Advanced gestation, maternal age, obesity, diabetes mellitus, and a combination of elevated D-dimer and interleukin-6 levels are predictive of poor pregnancy outcomes in COVID-19. The rate of iatrogenic preterm birth and cesarean delivery is high; vertical transmission may be possible but has not been proved.

Murine leukemia virus (MLV), a well-studied gammaretrovirus, has been often used as a representative retroviral vector. However, frequent integrations of MLV-based vectors into transcriptional start sites (TSSs) could lead to the activation of oncogenes by enhancer effects of the genetic components within the vectors. Therefore, the MLV integration preference for TSSs limits its wider use in clinical applications. To reduce the integration preference of MLV-based vectors, we attempted to perturb the structure of the viral integrase that plays a key role in determining integration sites. For this goal, we inserted histones and leucine zippers, having DNA-binding property, into internal sites of MLV integrase. This integrase engineering yielded multiple mutant vectors that showed significantly different integration patterns compared with that of wild-type vector. Some mutant vectors did not prefer the key regulatory genomic domains of human cells, TSSs. Moreover, a couple of engineered vectors did not integrate into the genomic sites near the TSSs of oncogenes. Overall, this study suggests that structural perturbation of integrase is a simple way to develop safer MLV-based retroviral vectors for use in clinical applications.This study was conducted to verify the relative expression patterns of SHOX2 and its regulation by tumor necrosis factor alpha (TNF-α) during the development of intervertebral disc degeneration (IVDD). A rat disc-degeneration model was subjected to disc puncture (DP) and intradiscal injections with TNF-α to determine the roles of TNF-α and SHOX2 expression in IVDD in vivo. TNF-α and SHOX2 expression patterns in different degenerative rat nucleus pulposus (NP) tissues were measured by immunohistochemistry (IHC). The effects of TNF-α on IVDD were determined by magnetic resonance imaging (MRI) and pain development of wet-dog shakes (WDS) were blinded assessment by pain-behavior testing, respectively. Changes in TNF-α on SHOX2 expression were measured by Western blot analysis and real-time reverse transcription polymerase chain reaction (RT-PCR). The roles of nuclear factor-κB (NF-κB) and mitogen-activated protein kinase (MAPK) in TNF-α-mediated SHOX2 activation were studied using viral transfection, Western blot analysis, and real-time RT-PCR. In vivo, TNF-α accelerated the process of IVDD and suppressed SHOX2 expression; compared to the DP group, WDS was significantly increased in TNF-α intradiscal injection group at 2 to 6 weeks after puncture (P  less then  .05); In NP cells, TNF-α negatively affected the IVDD-associated SHOX2 suppression. While TNF-α promotes IVDD through activation of both MAPK and NF-κB signaling, it seemed that only NF-κB signaling controlled the TNF-α-mediated SHOX2 suppression that is associated with IVDD. The results of this study indicated that TNF-α inhibits SHOX2 expression and has promoted effects on IVDD in the rat model, and these effects might be associated with through NF-κB signaling pathway and promotes IVDD and related pain in a rat model.

To examine the awareness, prevalence of use, and knowledge of risks of pepper injection (PI), an injection of highly concentrated oxytocin used to augment or induce labor, among clinicians.

An anonymous pre- and post-workshop evaluation conducted among 227 clinicians participating in emergency obstetric and newborn care training in Sierra Leone from June to October 2018.

Overall, 225 participants completed the surveys. Of these, 198 (88.0%) of clinicians reported awareness of PI, and 123 (54.7%) self-reported prior use, which was highest among midwives (94/129; 72.9%). Molibresib ic50 Before EmONC training, 82 (36.4%) clinicians reported that they were likely to use PI; this decreased to 39 (17.3%) after training (P<0.05). The mean number of participants correctly identifying risks of PI increased from 149 (66.2%) to 204 (90.7%) after training (P<0.05).

There was widespread awareness of PI use among clinicians, and prevalent self-reported prior use among midwives. Risk awareness improved after EmONC training, and the proportion of clinicians reporting likelihood of future use decreased.
