    Patients with ≥ 1 CTM3-4/6 mL have shorter median progression-free survival and median overall survival. Unlike CTM2 and CTM3-4, which are detectable in pre-therapy and post-therapy, larger aggregated CTM≥5 (CTM with ≥ 5 CTCs) was only intra-therapeutically detected in four HER2+ GC patients, of which three experienced liver metastases. Obtained results suggested that the cluster size of GC-CTM should be dynamically profiled beyond pre-therapeutic whole CTM enumeration in terms of chemo-/targeted resistance or metastasis monitoring. GC-CTM3-4 could be a potential indicator of therapeutic resistance, while the dynamic presence of GC-CTM≥5 implies liver metastasis in HER2+ GC patients.Human papillomavirus (HPV) infection identified as a definitive human carcinogen is increasingly being recognized for its role in carcinogenesis of human cancers. Up to 38%-80% of head and neck squamous cell carcinoma (HNSCC) in oropharyngeal location (OPSCC) and nearly all cervical cancers contain the HPV genome which is implicated in causing cancer through its oncoproteins E6 and E7. Given by the biologically distinct HPV-related OPSCC and a more favorable prognosis compared to HPV-negative tumors, clinical trials on de-escalation treatment strategies for these patients have been studied. It is therefore raised the questions for the patient stratification if treatment de-escalation is feasible. Moreover, understanding the crosstalk of HPV-mediated malignancy and immunity with clinical insights from the proportional response rate to immune checkpoint blockade treatments in patients with HNSCC is of importance to substantially improve the treatment efficacy. This review discusses the biology of HPV-related HNSCC as well as successful clinically findings with promising candidates in the pipeline for future directions. With the advent of various sequencing technologies, further biomolecules associated with HPV-related HNSCC progression are currently being identified to be used as potential biomarkers or targets for clinical decisions throughout the continuum of cancer care.

    The developer and sponsor of new cell-device and protein-device combination products in the United States needs to forecast which classification and designation to the regulatory scheme of biological products or devices would be required for the new products by the Food and Drug Administration (FDA). To improve the predictability and acceptability of the designation of new cell-device and protein-device combination products for innovators, developers, and sponsors, and to encourage the development and early access of new combination products, we proposed new visualization models of the designation pathway and group categorization.

    We searched the website of the FDA and the Alliance for Regenerative Medicine (ARM) on May 3, 2021 to identify the regulatory scheme of the FDA’s capsular decision cases of cell-device and protein-device combination products, and of the tissue-engineered products approved by the FDA.

    By introducing a new definition of the primary intended use (PIU) of developers and sponsors extracted from the classification factors of primary mode of action (PMOA), as well as drug-device and biologic-device combination products, we developed new visualization models of the designation pathway and the two-dimensional model of group categorization, and proposed a new group categorization of cell-device and protein-device combination products, focusing on the device component function.

    The new visualization models and the group categorization proposed in this study may increase the predictability and acceptability of the classification of newly developed cell-device and protein-device combination products to regulatory schemes in the US for innovators, developers, and sponsors.

To identify patients who are likely to be diagnosed with severe COVID-19, we analyzed the risk factors for mortality in patients admitted to the hematology department at our institute. The mortality rate of all patients was as high as 62% (21 of the 34 patients), and most of these patients had malignant malignancies. Patients before an achievement of remission had a 10.8-fold higher risk of death than those in remission. The group receiving chemotherapy with steroids had a shorter survival time and had an 8.3-fold higher risk of death than that receiving chemotherapy without steroids. During the COVID-19 pandemic, it is necessary to carefully monitor or follow-up patients with active diseases and patients receiving steroid-containing chemotherapy.

    Kidney stone disease seems to be associated with an increased risk of incident cardiovascular outcomes; the aim of this study is to identifydifferences in 24-h urine excretory profiles and stone composition among stone formers with and without cardiovascular disease (CVD).

    Data from patients attending the Department of Renal Medicine’s metabolic stone clinic from 1995 to 2012 were reviewed. The sample was divided according to the presence or absence of CVD (myocardial infarction, angina, coronary revascularization, or surgery for calcified heart valves). Univariable and multivariable regression models, adjusted for age, sex, BMI, hypertension, diabetes, eGFR, plasma bicarbonate and potential renal acid load of foods were used to investigate differences across groups.

    1826 patients had available data for 24-h urine analysis. Among these, 108 (5.9%) had a history of CVD. Those with CVD were older, have higher prevalence of hypertension and diabetes and lower eGFR. Univariable analysis showed that patients with CVD had significantly lower 24-h urinary excretions for citrate (2.4 vs 2.6 mmol/24 h, p = 0.04), magnesium (3.9 vs 4.2 mmol/24 h, p = 0.03) and urinary pH (6.1 vs 6.2, p = 0.02). After adjustment for confounders, differences in urinary citrate and magnesium excretions remained significant. No differences in the probability of stone formation or stone compositions were found.

    Stone formers with CVD have lower renal alkali excretion, possibly suggesting higher acid retention in stone formers with cardiovascular comorbidities. Randomized clinical trials including medications and a controlled diet design are needed to confirm the results presented here.
