RESUMEN
BACKGROUND: Nursing- and healthcare-associated pneumonia (NHCAP) constitutes most of the pneumonia in elderly patients including aspiration pneumonia in Japan. Lascufloxacin (LSFX) possesses broad antibacterial activity against respiratory pathogens, such as Streptococcus spp. And anaerobes inside the oral cavity. However, the efficacy and safety of LSFX in NHCAP treatment remains unknown. We aimed to evaluate the efficacy and safety of LSFX tablets in the treatment of patients with NHCAP. METHODS: In this single-arm, open-label, uncontrolled study, LSFX was administered to patients with NHCAP at 24 facilities. The study participants were orally administered 75 mg LSFX once daily for 7 days. The primary endpoint was the clinical efficacy at the time of test of cure (TOC). The secondary endpoints included clinical efficacy at the time of end of treatment (EOT), early clinical efficacy, microbiological efficacy, and safety analysis. RESULT: During the study period, 75 patients provided written informed consent to participate and were included. Finally, 56 and 71 patients were eligible for clinical efficacy and safety analyses, respectively. The median age of the patients was significantly high at 86 years. All patients were classified as having moderate disease severity using the A-DROP scoring system. LSFX tablets demonstrated high efficacy rates of 78.6 % at TOC and 89.3 % at EOT. The risk factors for resistant bacteria or aspiration pneumonia did not affect clinical efficacy. No severe adverse events associated with the study drugs were observed. CONCLUSION: Oral LSFX is an acceptable treatment option for moderate NHCAP in elderly patients who can take oral medications.

Objective Advance care planning (ACP) is a process in which the patient and family discuss end-of-life care in advance with healthcare providers in case decisional ability declines. Due to the rapid deterioration of symptoms and isolation for treatment, it is not easy for COVID-19 patients to discuss their end-of-life care with families and medical staff. We conducted a questionnaire survey to assess the current situation of ACP practices in hospitalized COVID-19 patients. Materials and methods Multicenter questionnaire surveys of hospitalized COVID-19 patients aged ≥60 years between January 2021 and August 2022 were conducted in two hospitals. The questionnaires assessed whether patients had discussed end-of-life medical treatment with their families and family physicians at the time of admission and their preferences for end-of-life medical treatments. Results A total of 109 patients aged 60-99 years (median 75.0 years) were enrolled. Only eight patients (7.3%) had practiced ACP at the time of admission. Age was a significant factor related to ACP practices (p=0.035). Although there was no significant difference between the ACP and non-ACP practiced groups for each end-of-life care, all eight patients in the ACP-practiced group were able to make decisions for all the end-of-life medical treatment, while 40 patients (33.0%) in the non-ACP-practiced group did not, showing a significant difference (p=0.026). Conclusion In hospitalized COVID-19 patients, the rate of ACP practice was as low as 7.3%. Awareness of ACP practice is necessary, especially for elderly patients with underlying diseases.
RESUMEN
We describe a rare case of a 20-year-old Japanese man with idiopathic pulmonary hemosiderosis (IPH) recurrence in adults with childhood onset (racIPH). IPH commonly occurs in children, and data regarding racIPH are lacking. A review of the literature showed that only five cases of racIPH have been reported (including the present case) and that racIPH shows features that are intermediate between childhood- and adult-onset IPH with respect to age and a lower frequency of smoking history. We also found that the degree of anemia was usually not severe, and a favorable response to corticosteroid therapy is expected in racIPH.

Lemierre's syndrome is a serious disease that typically causes oropharyngeal infection with internal jugular vein thrombosis, followed by distant infection focus, such as septic pulmonary embolism. The main causative organisms are anaerobic bacteria in the oral cavity, namely Fusobacterium necrophorum. We encountered an extremely rare case of Lemierre's syndrome, where double vision was found to be the first symptom. The patient's blood culture results showed the presence of F. nucleatum, which spread from the sphenoid sinus to the skull base because of chronic sinusitis; the patient presented with longus colli abscess, clivus osteomyelitis, venous thrombosis, and hematogenous infection. Antibiotic treatment with sulbactam/ampicillin was continued for 14 weeks, and no recurrence has been observed so far. Lemierre's syndrome can be complicated with atypical symptoms such as double vision if the cranial nerves are involved. It might be important to consider this disease in the differential diagnosis in the presence of cranial nerve symptoms of unknown origin with fever or inflammatory findings.

Plant hormones have been identified to be versatile signaling molecules essential for plant growth, development, and stress response. Their content levels vary depending on the species, and they also change in response to any external stimuli. Thus, simultaneous quantification of multiple plant hormones is required to understand plant physiology. Sensitive and quantitative analysis using liquid chromatography-linked mass spectrometry (LC-MS/MS) has been used in detecting plant hormones; however, quantification without stable isotopes is yet to be established. In this study, we quantified seven representative plant hormones of Lotus japonicus, which is a model legume for standard addition method. Accurate masses for monoisotopic ions of seven phytohormones were determined for high-resolution mass spectrometry (HR-MS). Selected ion monitoring (SIM) mode based on accurate masses was used in detecting phytohormones in the roots, stems, and leaves. Evaluation of matrix effects showed ion suppression ranging from 10.2% to 87.3%. Both stable isotope dilution and standard addition methods were able to detect plant hormones in the roots, stems, and leaves, with no significant differences in using both approaches and thus a standard addition method can be used to quantify phytohormones in L. japonicus. The method will be effective, especially when stable isotopes are not available to correct for matrix effects.
