Background An extrafine formulation triple therapy combination of beclomethasone dipropionate (BDP), formoterol fumarate (FF), and glycopyrronium bromide (GB) has been developed for the maintenance treatment of asthma and chronic obstructive pulmonary disease. This study used gamma scintigraphy to evaluate the intrapulmonary and extrapulmonary in vivo deposition of BDP/FF/GB, and the intrapulmonary regional distribution of the deposited formulation. Methods This open-label uncontrolled nonrandomized single-dose study recruited 10 healthy volunteers and 9 patients with asthma. After a krypton-81m (81mKr) ventilation scan was conducted, subjects inhaled study drug (four inhalations of BDP/FF/GB 100/6/12.5 μg radiolabeled using technetium-99 m [99mTc]) through pressurized metered-dose inhaler, and a series of scintigraphic images were taken. The primary objective was to evaluate intrapulmonary drug deposition of BDP/FF/GB, determined as the percentage of nominal (i.e., metered) dose. Secondary endpoints includedpheral regions. Importantly, the deposition patterns were similar in healthy volunteers and patients with asthma, suggesting that disease characteristics are unlikely to impact drug deposition. Clinical Trial Registration number NCT03795350.Background Chemotherapy-induced peripheral neuropathy (CIPN) is a common and debilitating side effect of cancer treatment with no effective preventative strategy or definitive treatment. Purpose To synthesize empiric literature from randomized controlled trials (RCTs) of pharmacological and nonpharmacological management of CIPN. Data Sources Articles published between January 1, 2010, and February 28, 2021, were identified using keywords searching Medline, PubMed, CINAHL, Web of Science, Cochrane Library, and Embase. Study Selection RCTs that recruited individuals who were post-chemotherapy and experienced persistent CIPN symptoms. Data Extraction and Synthesis Three independent reviewers screened a total of 2023 abstracts. After screening, full-text review, and quality appraisal, 22 articles were included in this review. Data related to study design, participant characteristics, interventions, controls, outcome measures, and relevant findings were extracted from full texts. Descriptive quantitative summaries may require a multipronged approach and should be tailored to the individual. Clinical implications are proposed and suggestions made for future research include implementation of standardized intervention protocols, use of outcome measures representative of the spectrum of CIPN symptoms, and stratification by the chemotherapeutic agent.Objective Report a large single-institution cohort of quality of life (QOL) data before and after facial feminization surgery (FFS). Study Design Case series. Methods Patients who underwent FFS at our institution between 2017 and 2019 and completed a pre- and postoperative QOL survey were included in this study. Responses were scored on a 5-point scale with 1 corresponding to least agreement and 5 corresponding to most agreement. Paired t-test was used to compare pre- and postoperative mean scores for each response. Two-tailed t-test was used to compare the mean postoperative delta for each response by demographics. Results One hundred seven of 341 patients completed a pre- and postoperative survey. The average age was 36 years (range 18-67). The mean time to postoperative survey completion was 96 days (interquartile range 43). Significant improvements in all aspects of QOL assessed on the survey were noted after surgery, including self-perceived facial femininity (2.1-3.8, p  less then  0.001) and publicly perceived facial femininity (2.0-3.6, p  less then  0.001). Patients also felt less limited in social activities (3.2-2.0, p  less then  0.001) and professional activities (2.7-1.7, p  less then  0.001). Conclusion FFS improves self-perceived and externally perceived facial femininity and reduces limitations in social and professional activities.Ovarian cancer (OC) is known to be the most malignant gynecologic cancers. Wnt2B, a member of the Wnt family, plays a critical role in tumor development. However, the effect of Wnt2B on the occurrence and development of OC remains largely uncharacterized. In this study, immunohistochemistry assay indicated that Wnt2B was increased in our study cohort (OC). In addition, the expression of Wnt2B was positively correlated with TNM stages and metastasis of OC patients. Wnt2B markedly mediated the regulation of OC proliferation, invasion, and angiogenesis. Moreover, Wnt2B knockdown inactivated the Wnt/β-catenin signaling pathway. More importantly, the Wnt/β-catenin signaling pathway activator LiCl reversed the effect of Wnt2B knockdown on OC cell proliferation, angiogenesis, and invasion. Our data indicated that Wnt2B silencing could inhibit the proliferation, invasion, and angiogenesis of OC cells through downregulating the activity of Wnt/β-catenin pathway.Background The effectiveness of 18F-fluorodeoxyglucose (18F-FDG) positron emission computed tomography (PET/CT) for monitoring response to immunotherapy (IT) with cemiplimab in patients affected by cutaneous squamocellular carcinoma (cSCC) was investigated. Materials and Methods Thirteen cSCC patients performed PET/CT at baseline (PET-1) and 3 months after IT (PET-2). According to immune PET Response Criteria in Solid Tumors (iPERCIST), patients showing progressive disease at PET-2 were classified as having "unconfirmed progressive metabolic disease" (uPMD) and were scheduled to perform a further PET/CT (PET-3) after 4 weeks. PET/CT's results were correlated with best clinical response (BCR) categorized, within 6 months from the start of IT, as clinical benefit (CB) or no clinical benefit (NCB) according to clinical follow-up. Results At PET-2, 9 subjects (69.2%) showed metabolic response, whereas four (30.8%) were classified as uPMD. After 4 weeks, three uPMD patients were subjected to PET-3, which confirmed progressive disease in all cases, whereas 1 patient with uPMD did not undergo PET-3 due to clinical deterioration. All subjects with metabolic response at PET-2 were classified as having CB and continued IT in 8 out of 9 cases, whereas all patients with uPMD were categorized as NCB and discontinued IT. Conclusions PET/CT, performed in cSCC patients after 3 months of cemiplimab, resulted capable to identify responders from nonresponders.Aim Identify and describe published literature on the use of subcutaneous immunoglobulin (SCIG) as initial immunoglobulin (IG)-replacement therapy for patients with primary immunodeficiency diseases (PID). Methods We systematically identified and summarized literature in MEDLINE, Embase, BioSciences Information Service and Cochrane Library assessing efficacy/effectiveness, safety/tolerability, health-related quality-of-life (HRQoL) and dosing regimens of SCIG for IG-naive patients with PID. Results Sixteen studies were included. In IG-naive patients, SCIG managed/reduced infections and demonstrated similar pharmacokinetic parameters to IG-experienced patients; adverse events were mostly minor injection-site pain or discomfort. Three studies reported improvements in HRQoL. Quality of studies was difficult to assess due to limited reporting. Conclusion Although studies were lacking, available data suggest IG-naive and IG-experienced patients initiating SCIG likely have similar outcomes.Aim The emergence of antitumor immunotherapy has been beneficial for patients with tumors, but more attention should be paid to the toxic side effects of chemoimmunotherapy. SZL P1-41 mw Here we describe a patient with NK/T-cell lymphoma who developed toxic epidermal necrolysis (TEN) during treatment with a regimen consisting of sintilimab combined with pegaspargase, gemcitabine and oxaliplatin (P-GemOx). Case presentation A patient received six cycles of P-GemOx chemotherapy as first-line treatment; 1 year later, he received the same dose of P-GemOx combined with sintilimab as chemoimmunotherapy due to recurrence of NK/T-cell lymphoma. He developed a massive rash that quickly developed into TEN after the fourth chemoimmunotherapy. Conclusion Although rare, cases of fatal TEN caused by single-agent PD-1 inhibitor or gemcitabine have been reported. Careful attention to drug-related cutaneous toxicities is needed when these two agents are combined. This report highlights the significance of TEN as a rapid and serious adverse event induced by chemoimmunotherapy.Laccase is a novel target for fungicides. We previously developed a new fungicide, 4-chlorocinnamaldehyde thiosemicarbazide (PMDD-5Y), as a laccase inhibitor. The introduction of active groups of natural products into the framework of a pesticide molecular structure is an effective method for discovering active lead compounds, and it has applications in the discovery of new pesticides. In this work, PMDD-5Y was selected as a lead compound, and we designed and synthesized a series of novel sulfonyl hydrazide derivatives containing the natural product scaffold 1,2,3,4-tetrahydroquinoline. The new compounds had antifungal activities against several fungi, especially Valsa mali and Sclerotinia sclerotiorum. One compound (4bl) displayed very good in vitro activity against S. sclerotiorum and V. mali, with EC50 values of 3.32 and 2.78 μg/mL, respectively. The results of an enzyme activity assay showed that 4bh had the best inhibitory activity against laccase, with an EC50 value of 14.85 μg/mL. This was more active than the lead compound PMDD-5Y and the positive control cysteine. Using a molecular docking method, we studied the binding mode of the title compounds with laccase. The structural features of these new laccase inhibitors as fungicides will advance research and impact the field of discovering more potent fungicides to control diseases in agriculture.A palladium-catalyzed divergent carbonylative synthesis of indoles and 4H-benzo[d][1,3]oxazines from 2-alkynylanilines and benzyl chlorides with benzene-1,3,5-triyl triformate (TFBen) as the CO source has been developed. The reaction using AlCl3 as the additive produced various indoles in high yields, while a series of 4H-benzo[d][1,3]oxazines was achieved in moderate yields with AcOH as the additive.Electrochemical CO2 reduction (ECR) promises the replacement of fossil fuels as the source of feedstock chemicals and seasonal storage of renewable energy. While much progress has been made in catalyst development and electrochemical reactor design, few studies have addressed the effect of catalyst integration on device performance. Using a microfluidic gas diffusion electrolyzer, we systematically studied the effect of thickness and the morphology of electron beam (EB) and magnetron-sputtered (MS) Cu catalyst coatings on ECR performance. We observed that EB-Cu outperforms MS-Cu in current density, selectivity, and energy efficiency, with 400 nm thick catalyst coatings performing the best. The superior performance of EB-Cu catalysts is assigned to their faceted surface morphology and sharper Cu/gas diffusion layer interface, which increases their hydrophobicity. Tests in a large-scale zero-gap electrolyzer yielded similar product selectivity distributions with an ethylene Faradaic efficiency of 39% at 200 mA/cm2, demonstrating the scalability for industrial ECR applications.
