Atopic dermatitis disease registry in Japanese adult patients with moderate to severe atopic dermatitis (ADDRESS‐J): Baseline characteristics,treatment history and disease burden

Moderate to severe atopic dermatitis (AD) has a high disease burden and a significant effect on quality of life. Observational studies are necessary to determine the patient disease burden and long‐term disease control in the Japanese population. ADDRESS‐J is a non‐interventional, observational registry of adult Japanese patients with moderate to severe AD. Herein, we report baseline data from the ADDRESS‐J study describing disease characteristics and current treatment practices. At baseline, 300 adult AD patients with Investigator's Global Assessment (IGA) scores (range, 0–4) of 3 (moderate) or 4 (severe) whose treatments for AD were intensified, were assessed for clinical and patient‐reported outcomes and current AD treatments. The registry patients’ median age was 34.0 years; 60.7% were male and 71.7% had had AD for more than 20 years. At baseline, 220 study patients had an IGA score of 3 and 80 had an IGA score of 4. The median Eczema Area and Severity Index score was 21.7 (range, 0–72), the median body surface area involvement was 46.25%, and the median pruritus numerical rating scale score was 7.0 (range, 0–10); for each of these measures, higher scores represent greater severity. Most registry patients (86.7%) had recently used topical corticosteroids or topical calcineurin inhibitors as treatment for AD. This registry cohort represents a population of Japanese patients with moderate to severe AD and provides an important resource for characterizing the disease burden and evaluating the safety and effectiveness of various AD treatments.     

Feasibility and utility of transbronchial cryobiopsy in precision medicine for lung cancer: Prospective single‐arm study

Cryoprobe is a novel transbronchial biopsy (TBB) tool that yields larger tissue samples than forceps. Pathological diagnosis and biomarker analysis, such as genetic alterations and programmed death‐ligand 1 (PD‐L1) expression, are paramount for precision medicine against lung cancer. We evaluated the safety and usefulness of cryoprobe TBB for lung cancer diagnosis and biomarker analysis. In this single‐center, prospective single‐arm study, patients suspected of having or diagnosed with primary lung cancer underwent cryoprobe TBB using flexible bronchoscopy after conventional forceps TBB from the same lesion. Cryoprobe TBB was performed in 121 patients. The incidence rate of severe bleeding and serious adverse events (4% [90% confidence interval: 2%‐9%]) was significantly lower than the expected rate (20% with 30% threshold, P < 0.01). Combining both central and peripheral lesions, the diagnostic yield rate of cryoprobe samples was 76% and that of forceps samples was 84%. Compared with forceps TBB samples, cryoprobe TBB samples were larger (cryoprobe 15 mm² vs forceps 2 mm²) and resulted in a larger proportion of definite histomorphological diagnosis (cryoprobe 86% vs forceps 74%, P < 0.01), larger amounts of DNA extracted from samples (median: cryoprobe, 1.60 µg vs forceps, 0.58 µg, P = 0.02) and RNA (median: cryoprobe, 0.62 µg vs forceps, 0.17 µg, P < 0.01) extracted from samples, and tended to yield greater rates of PD‐L1 expression >1% (51% vs 42%). In conclusion, cryoprobe is a safe and useful tool for obtaining lung cancer tissue samples of adequate size and quality, which allow morphological diagnosis and biomarker analysis for precision medicine against lung cancer.     

Evolutionary‐adaptive and nonadaptive causes of infant attack/desertion in mammals: Toward a systematic classification of child maltreatment

Behaviors comparable to human child maltreatment are observed widely among mammals, in which parental care is mandatory for offspring survival. This article first reviews the recent findings on the neurobiological mechanisms for nurturing (infant caregiving) behaviors in mammals. Then the major causes of attack/desertion toward infants (conspecific young) in nonhuman mammals are classified into five categories. Three of the categories are ‘adaptive’ in terms of reproductive fitness: (i) attack/desertion toward non‐offspring; (ii) attack/desertion toward biological offspring with low reproductive value; and (iii) attack/desertion toward biological offspring under unfavorable environments. The other two are nonadaptive failures of nurturing motivation, induced by: (iv) caregivers’ inexperience; or (v) dysfunction in caregivers’ brain mechanisms required for nurturing behavior. The proposed framework covering both adaptive and nonadaptive factors comprehensively classifies the varieties of mammalian infant maltreatment cases and will support the future development of tailored preventive measures for each human case. Also included are remarks that are relevant to interpretation of available animal data to humans: (1) any kind of child abuse/neglect is not justified in modern human societies, even if it is widely observed and regarded as adaptive in nonhuman animals from the viewpoint of evolutionary biology; (2) group‐level characteristics cannot be generalized to individuals; and (3) risk factors are neither deterministic nor irreversible.     

Combined effect of a direct oral anticoagulant edoxaban and an inhibitor of activated thrombin-activatable fibrinolysis inhibitor on clot lysis

Journal of Thrombosis and Thrombolysis - Fibrinolysis is regulated by the thrombin/thrombin-activatable fibrinolysis inhibitor (TAFI) system. Thus, anticoagulants and inhibitors of TAFI are...
