A 70-year-old Japanese man with well-controlled diabetes mellitus and chronic kidney disease was hospitalized for an examination of acute renal failure and elevated inflammatory reactions. He had a history of Klebsiella pneumoniae bacteremia without extended-spectrum β-lactamase (ESBL) production five months earlier. The patient was found to have bacteremia due to hypermucoviscous ESBL-producing Klebsiella pneumoniae, and developed septic shock, multiple cerebral infarctions, and an abscess in the left masticatory muscle space.

Background: It is unclear how primary care physicians manage insomnia after the introduction of novel hypnotics such as orexin receptor antagonists and melatonin receptor agonists. This Web-based questionnaire survey aimed to examine treatment strategies for insomnia in Japanese primary care practice.

Methods: One-hundred-and-seventeen primary care physicians were surveyed on the familiarity of each management option for insomnia on a binary response scale (0 = "unfamiliar"; 1 = "familiar") and how they managed insomnia using a nine-point Likert scale (1 = "I never prescribe/perform it"; 9 = "I often prescribe/perform it").

Article Synopsis
  • Stenotrophomonas maltophilia is a carbapenem-resistant pathogen linked to challenging hospital infections, with a study analyzing its clinical characteristics and genetic makeup across six Japanese hospitals.
  • The study included 78 patients, primarily elderly males with serious comorbidities, showing that those with infections had a notably higher mortality rate compared to those who were merely colonized.
  • While the bacteria predominantly colonized the respiratory tract, infection cases, particularly bacteraemia, led to higher mortality rates; sulfamethoxazole/trimethoprim was found to be the most effective antibiotic against it.

Background: The use of posterior lumber interbody fusion (PLIF) using cortical bone trajectory (CBT) with a patient-specific 3D template guide is increasingly widespread. To our knowledge, no studies have extensively evaluated the reduction of radiation exposure when using patient-specific drill template guides. The purpose of this study is to compare the intra-operative radiation dose and surgeon's exposure to radiation in CBT-PLIF when using a patient-specific drill guide with that in traditional minimally invasive (MIS)-PLIF.

Article Synopsis
  • Carbapenemase-producing Enterobacteriaceae (CPEs) are major antimicrobial-resistant pathogens, with metallo-β-lactamases (MBLs) like Imipenemase (IMP) posing significant treatment challenges due to limited effective medication options.
  • A study evaluated 62 hospitalized patients in Japan with IMP-producing infections, finding most isolates in sputum and identifying common sequence types among them.
  • The research highlighted that while some patients received effective traditional treatments, mortality rates were notable, especially in patients with existing health conditions, contrasting with infections linked to more widely spread MBLs like NDM and VIM.

β-Lactamases can accumulate stepwise mutations that increase their resistance profiles to the latest β-lactam agents. CMY-185 is a CMY-2-like β-lactamase and was identified in an clinical strain isolated from a patient who underwent treatment with ceftazidime-avibactam. CMY-185, possessing four amino acid substitutions of A114E, Q120K, V211S, and N346Y relative to CMY-2, confers high-level ceftazidime-avibactam resistance, and accumulation of the substitutions incrementally enhances the level of resistance to this agent.
