Computed tomography (CT)-based attenuation correction (CTAC) in single-photon emission computed tomography (SPECT) is highly accurate, but it requires hybrid SPECT/CT instruments and additional radiation exposure. To obtain attenuation correction (AC) without the need for additional CT images, a deep learning method was used to generate pseudo-CT images has previously been reported, but it is limited because of cross-modality transformation, resulting in misalignment and modality-specific artifacts. This study aimed to develop a deep learning-based approach using non-attenuation-corrected (NAC) images and CTAC-based images for training to yield AC images in brain-perfusion SPECT. This study also investigated whether the proposed approach is superior to conventional Chang's AC (ChangAC).

In total, 236 patients who underwent brain-perfusion SPECT were randomly divided into two groups the training group (189 patients; 80%) and the test group (47 patients; 20%). Two models were constructed using Autoencoder (C. We generated highly accurate AC images directly from NAC images without the need for intermediate pseudo-CT images. To verify our models' generalizability, external validation is required.

New deep learning-based AC methods for AutoencoderAC and U-NetAC were developed. Their accuracy was higher than that obtained by ChangAC. U-NetAC exhibited higher qualitative and quantitative accuracy than AutoencoderAC. We generated highly accurate AC images directly from NAC images without the need for intermediate pseudo-CT images. To verify our models' generalizability, external validation is required.Hand, foot, and mouth disease (HFMD) caused by enterovirus A71 (EV-A71) is a contagious viral disease, and toll-like receptors (TLRs) play essential roles in resisting the pathogen. The aim of this study was to assess the potential relationship between several TLRs polymorphisms and the HFMD severity in a Chinese children population. A total of 328 Chinese children with HFMD were included in the present study. The polymorphisms of TLR3 (rs3775290, rs3775291, rs3775296, rs1879026, rs5743312, rs5743313, rs5743303, rs13126816, and rs3775292), TLR4 (rs4986790, rs4986791, rs2149356, rs11536889, and rs41426344), TLR7 (rs179009, rs179010, rs179016, rs3853839, rs2302267, rs1634323, and rs5741880), and TLR8 (rs3764880, rs2159377, rs2407992, rs5744080, rs3747414, rs3764879, and rs5744069) genes were selected. The study indicated that individuals with the GG genotype of TLR3 single-nucleotide polymorphism rs1879026 had a higher risk of developing severe cases (GG vs. GT OR = 1.875; 95% CI, 1.183-2.971; p = .007). Meanwhile, TLR3 rs3775290 CC genotype and C allele were associated with lower disease severity in females (CC vs. CT OR = 0.350; 95% CI, 0.163-0.751; p = .006; C vs. T OR = 0.566; 95% CI, 0.332-0.965; p = .036). TLR3 rs3775291 CC genotype showed 2.537 folds higher risk of developing severe cases in females (CC vs. CT OR = 2.537; 95% CI, 1.108-5.806; p = .026). Moreover, TLR3 rs1879026 GG genotype was found to be related to increased risk of severe cases in males (GG vs. GT OR = 2.076; 95% CI, 1.144-3.768; p = .016). The current findings show that the genetic variants of TLR3 rs1879026, rs3775290, and rs3775291 are associated with the severity of EV-A71-associated HFMD in a Chinese children population.Extranodal natural killer (NK)/T-cell lymphoma (NKTL) is a rare non-Hodgkin lymphoma that rarely arise exclusively in or metastasizes to the central nervous system (CNS). Globally, CNS involvement of NKTL heralds a serious prognosis and there is no standard treatment. Baxdrostat datasheet 19 of 414 patients (4.59%) with ENKL followed were diagnosed with CNS involvement between 2006 and 2020. Two patients had primary CNS (PCNS) NKTL, and 17 patients had secondary CNS (SCNS) invasion. A total of 9 patients survived and 10 patients died. The median overall survival time was 55 months, and the median survival time after CNS invasion was 17 months. The 5-year cumulative survival probability was 45.7%. In conclusion, CNS risk evaluation and prophylaxis treatment can be carried out for patients with NK/T-cell lymphoma prognostic index risk group III/IV. In terms of treatment, systemic therapy based on methotrexate combined with radiotherapy and intrathecal chemotherapy can be selected.The coronavirus disease 2019 (COVID-19) pandemic has focused attention on the need to develop effective therapeutics against the causative pathogen, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and also against other pathogenic coronaviruses. In this study, we report on a kind of bisbenzylisoquinoline alkaloid, neferine, as a pan-coronavirus entry inhibitor. Neferine effectively protected HEK293/hACE2 and HuH7 cell lines from infection by different coronaviruses pseudovirus particles (SARS-CoV-2, SARS-CoV-2 [D614G, N501Y/D614G, 501Y.V1, 501Y.V2, 501Y.V3 variants], SARS-CoV, MERS-CoV) in vitro, with median effect concentration (EC50 ) of 0.13-0.41 μM. Neferine blocked host calcium channels, thus inhibiting Ca2+ -dependent membrane fusion and suppressing virus entry. This study provides experimental data to support the fact that neferine may be a promising lead for pan-coronaviruses therapeutic drug development.Although Crimean-Congo hemorrhagic fever (CCHF) is mild and self-limited in children, some patients may develop excessive bleeding, massive liver necrosis, and multiple organ failure associated with secondary hemophagocytic lymphohistiocytosis (HLH) induced by cytokine storm. Treatment of CCHF is mainly symptomatic and supportive. The efficacy of ribavirin, which is the only antiviral drug in the treatment of CCHF, remains controversial. Although therapeutic plasma exchange (TPE) has been shown to beneficial in small case series with primary and secondary HLH, there is no pediatric patient with HLH secondary to CCHF treated with TPE in the literature. In this report, we describe the first pediatric patient who was successfully recovered from HLH secondary to CCHF with ribavirin, intravenous immunoglobulin, and TPE.
