Yukiya Suzuki,Honami Suzuki,Ryogo Umetsu,Hiroaki Uranishi,Junko Abe,Yuri Nishibata,Yasuaki Sekiya,Nobuteru Miyamura,Hideaki Hara,Teruo Tsuchiya,Yasutomi Kinosada,Mitsuhiro Nakamura +11 more
TL;DR: The use of PPIs as a preventive measure against GI hemorrhagic events for patients receiving clopidogrel and aspirin is supported, and PPIs had little influence on the adjusted ROR of embolic/thrombotic events.

TL;DR: The incidence of BRONJ with BP treatment should be closely monitored for a 3-year period and the lower 95 % confidence interval of the Weibull-shape parameter β for I.V. BPs (pamidronate and zoledronate) exceeded 1.1, and it is believed that this information aboutBRONJ induced by BPs will prove beneficial to patients and pharmacists.

TL;DR: Elderly individuals should be closely monitored for the occurrence of renal disorder when they are subjected to polypharmacy, as well as the effect of patient-related factors using a multiple-logistic regression technique and data subsetting.
Association between Selective Serotonin Reuptake Inhibitor Therapy and Suicidality: Analysis of U.S. Food and Drug Administration Adverse Event Reporting System Data
Ryogo Umetsu,Junko Abe,Natsumi Ueda,Yamato Kato,Toshinobu Matsui,Yoko Nakayama,Yasutomi Kinosada,Mitsuhiro Nakamura +7 more
TL;DR: Ass associations between SSRI treatment and suicidal and self-harm events were stronger in the <18 y.o. group than other age groups and data subsetting might mitigate the effect of an intrinsic risk among patients taking the suspected drug.
Hyperglycemic adverse events following antipsychotic drug administration in spontaneous adverse event reports.
Yamato Kato,Ryogo Umetsu,Junko Abe,Natsumi Ueda,Yoko Nakayama,Yasutomi Kinosada,Mitsuhiro Nakamura +6 more
TL;DR: Antipsychotic drug polypharmacy may influence signal strength, and may be associated with hyperglycemia, and further robust epidemiological studies are recommended.
