The incidence of human papillomavirus (HPV)-related oropharyngeal cancer (OPC) has increased, and staging and optimal therapeutic approaches are challenging. A questionnaire survey was conducted to investigate the controversial treatment policy of stage T2 OPC according to the N category and determine the opinions of multidisciplinary experts in Korea.

Five OPC scenarios were developed by the Subcommittee on Oropharyngeal Treatment Guidelines of the Korean Society for Head and Neck Oncology and distributed to experts of multidisciplinary treatment hospitals.

Sixty-five experts from 45 institutions responded. For the HPV-positive T2N0M0 scenario, 67.7% of respondents selected surgery followed by definitive concurrent chemoradiotherapy (CCRT) or radiotherapy alone. For the T2N1M0 HPV-positive scenario, there was a notable difference in the selection of primary treatment by expert specialty; 53.9% of respondents selected surgery and 39.8% selected definitive CCRT as the primary treatment. For the T2N3M0 adspecialty. Multidisciplinary consensus guidelines will be essential in the future.
Capmatinib, an oral MET kinase inhibitor, has demonstrated its efficacy against non-small cell lung cancer (NSCLC) with MET dysregulation. We investigated its clinical impact in advanced NSCLC with MET exon 14 skipping mutation or gene amplification.

Patients who participated in the screening of a phase II study of capmatinib for advanced NSCLC were enrolled in this study. MET gene copy number (GCN), protein expression, and METex14 were analyzed and the patients' clinical outcome were retrospectively reviewed.

A total of 72 patients were included in this analysis (Group A GCN ≥ 10 or METex14, n=14; Group B others, n=58). Among them, 13 patients were treated with capmatinib (Group A, n=8; Group B, n=5), and the overall response rate was 50% for Group A, and 0% for Group B. limertinib price In all patients, the median overall survival (OS) was 20.2 months (95% CI, 6.9 - NA) for Group A, and 11.3 months (95% CI, 8.2 - 20.3) for Group B (p=0.457). However, within Group A, median OS was 21.5 months (95% CI, 20.8 - NA) for capmatinib-treated, and 7.5 months (95% CI, 3.2 - NA) for capmatinib-untreated patients (p=0.025). Among all capmatinib-untreated patients (n=59), Group A showed a trend towards worse OS to Group B (median OS 7.5 vs. 11.3 months, p=0.123).

Our data suggest that capmatinib is a new compelling treatment for NSCLC with MET GCN ≥ 10 or METex14 based on the improved survival within these patients.

Angiosarcoma is a highly aggressive mesenchymal tumor. Although systemic chemotherapy is often considered for the inoperable or metastatic angiosarcoma, the outcome of such treatment is unsatisfactory and poorly delineated.

We reviewed electronic medical records of 75 patients with angiosarcoma who were treated with systemic chemotherapy for inoperable or metastatic disease. Patients were classified as having liver involvement if they had either primary or metastatic hepatic lesions.

Among the patients evaluated, 51 patients were male (68%) and 24 patients (32%) had primary cutaneous angiosarcoma. Liver involvement was present in 28 patients (37.3%). A total of 59 patients received first-line weekly paclitaxel (wPac) and showed an objective response rate (ORR) of 23.7% (n=14), a median progression free survival (mPFS) of 4.0 months (95% confidence interval [CI] 3.0-6.1), and a median overall survival (mOS) of 10.2 months (95% CI 7.0-14.6). Among patients without liver involvement, patients receiving wPac (n=35) had significantly prolonged mPFS (5.8 vs. 3.2 months, respectively, p=0.014) with a tendency for prolonged mOS (13.8 vs. 11.6 months, respectively, p=0.13) than those receiving other regimens (n=12). A total of 24 patients received second- or later-line pazopanib monotherapy and showed an ORR of 16.7% (n=4), a mPFS of 2.4 months (95% CI 1.8-4.3) and a mOS of 5.4 months (95% CI 3.5-NA).

Treatment with first-line wPac and later-line pazopanib seems to provide survival benefit, especially for patients with advanced angiosarcoma without liver involvement.

The Three Delays Model outlines, three common delays that lead to poor newborn outcomes (i) recognising symptoms and deciding to seek care; (ii) getting to care and; (iii) receiving timely, high-quality care. We gathered data for all newborn deaths within four districts in Ghana to explore how well the Three Delays Model explains outcomes.

In this cross-sectional, observational study, trained field workers conducted verbal and social autopsies with the closest surviving relative (typically mothers) of all neonatal deaths across four districts in northern Ghana from September 2015 until April 2017. Data were collected using Survey CTO and analysed using StataSE 15.0. Frequencies and descriptive statistics were calculated for key variables.

247 newborn deaths were identified. Nearly 77% (190) of newborns who died were born at a health facility, and 48.9% (93) of those who died before discharge. Of the 149 newborns who were discharged or born at home, 71.8% (107) sought care at a facility for illness, and 72.9% (N=78) of those did so within the same day of illness recognition. Of the 83 respondents who arranged for transportation, 82% (68) did so within 1h. Newborns received prompt care but insufficient interventions - 25% or fewer received IV fluids, oral medications, antibiotics or oxygen.

These data suggest that women are following recommendations for safe delivery and prompt care-seeking. In rural northern Ghana, behaviour change interventions focused on mothers and families may not be as pressing as interventions focused on the Third Delay - obtaining timely, high-quality care.

In this study, we confirmed that LPAR5 is upregulated in papillary thyroid carcinoma (PTC), especially in BRAF-like PTC, by analyzing The Cancer Genome Atlas (TCGA) database and performing immunohistochemistry assay in human thyroid cancer tissues. LPAR5-specific antagonist TC LPA5 4 treatment inhibited CGTH-W3, TPC-1, B-CPAP, and BHT-101 cell proliferation, CGTH-W3 and TPC-1 cell migration significantly. In vivo, TC LPA5 4 treatment could delay CGTH-W3 xenograft growth in nude mice. We also found that LPAR5-specific antagonist TC LPA5 4, PI3K inhibitor wortmannin, or mTOR inhibitor rapamycin pretreatment abrogated phosphorylation of Akt and p70S6K1 stimulated by LPA in CGTH-W3 and TPC-1 cells. Stimulating CGTH-W3 cells transfected with pEGFPC1-Grp1-PH fusion protein with LPA resulted in the generation of phosphatidylinositol (3,4,5)-triphosphate, which indicates that PI3K was activated by LPA directly. The p110β-siRNA instead of p110α-siRNA transfection abrogated the increase of levels of phosphorylated Akt and S6K1 stimulated by LPA. Furthermore, immunoprecipitation assay confirmed an interaction between LPAR5 and p110β. Overall, we provide new insights that the downregulation of LPAR5 decreased the proliferation and migration phenotype via the PI3K/Akt pathway. Inhibition of LPAR5 or the PI3K/Akt signal may be a novel therapeutic strategy for treating thyroid cancer.The conformational preferences of oligomers of δ-amino acid (δAc5 a) with a cyclopentyl constraint in the Cβ -Cγ bond of the backbone were investigated by using DFT methods in the gas phase and in solution. The folded structures with C10 H-bonded pseudocycles were most preferred for dimer and tetramer of δAc5 a residues both in chloroform and water. However, for the hexameric Ac-(δAc5 a)6 -NHMe, the mixed H16/14 helical structure was found to be most preferred in chloroform (populated at 68 %), whereas the H14 helical structure was the most dominant conformation in water (populated at 60 %). The stability of the former was ascribed to the intrinsic conformational energy, whereas the solvation free energy was crucial to stabilize the latter. Pyrrolidine-substituted analogues of the hexameric Ac-(δAc5 a)6 -NHMe, with adjacent amine diads that are almost exactly one turn apart with two nitrogen atoms separated by ca. 5.5 Å, adopted helical structures. They are potential catalysts in nonpolar and polar solvents as they have similar structures to a helical 1  2 αβ-heptapeptide that exhibited good catalytic performance in the crossed aldol condensation.
Patients are prioritized for liver transplant under an 'urgency-based' system using the Model for End Stage Liver Disease score. This system focuses solely on waitlist mortality, without considerations of post-transplant morbidity, mortality, and healthcare utilization. We sought to develop and internally validate a continuous post-transplant risk score over 5- and 10-year time horizons.

This retrospective cohort study used national registry data of adult deceased-donor liver transplant (DDLT) recipients with ≥90 days of pre-transplant waiting time from 2/27/02-12/31/18. We fit Cox regression models at 5 and 10 years to estimate beta coefficients for a risk score using manual variable selection and calculated absolute predicted survival time.

Among 21,103 adult DDLT recipients, 11 variables were selected for the final model. The AUC's at 5- and 10-years were 0.63, 95% CI 0.60-0.66 and 0.67, 95% CI 0.64-0.70, respectively. The group with the highest ('best') scores had 5- and 10-year survivals of 89.4% alocation) rather than simply waitlist mortality.We report the synthesis and characterization of a fullerene-steroid hybrid that contains H2 @C60 and a dehydroepiandrosterone moiety synthesized by a cyclopropanation reaction with 76 % yield. Theoretical calculations at the DFT-D3(BJ)/PBE 6-311G(d,p) level predict the most stable conformation and that the saturation of a double bond is the main factor causing the upfield shielding of the signal appearing at -3.13 ppm, which corresponds to the H2 located inside the fullerene cage. Relevant stereoelectronic parameters were also investigated and reinforce the idea that electronic interactions must be considered to develop studies on chemical-biological interactions. A molecular docking simulation predicted that the binding energy values for the protease-hybrid complexes were -9.9 kcal/mol and -13.5 kcal/mol for PLpro and 3CLpro respectively, indicating the potential use of the synthesized steroid-H2 @C60 as anti-SARS-Cov-2 agent.Few therapeutic options exist for treatment of IC/BPS. A novel high MW GAG biopolymer ("SuperGAG") was synthesized by controlled oligomerization of CS, purified by TFF and characterized by SEC-MALLS and 1H-NMR spectroscopy. The modified GAG biopolymer was tested in an OVX female rat model in which bladder permeability was induced by a 10-minute intravesicular treatment with dilute (1 mg/ml) protamine sulfate and measured by classical Ussing Chamber TEER measurements following treatment with SuperGAG, chondroitin sulfate, or saline. The effect on abrogating the abdominal pain response was assessed using von Frey filaments. The SuperGAG biopolymer was then investigated in a second, genetically modified mouse model (URO-MCP1) that increasingly is accepted as a model for IC/BPS. Permeability was induced with a brief exposure to a sub-noxious dose of LPS and was quantified using contrast-enhanced MRI (CE-MRI). The SuperGAG biopolymer restored impermeability to normal levels in the OVX rat model as measured by TEER in the Ussing chamber and reduced the abdominal pain response arising from induced permeability.
