RESUMEN
BACKGROUND: We aimed to improve the prognosis, treatment, and management of Staphylococcus aureus bacteremia (SAB) by evaluating the association between adherence to quality indicators (QIs) and clinical outcomes in patients with their clinical outcomes. METHODS: We retrospectively collected clinical and microbiological data on hospitalized patients with SAB from 14 hospitals (three with > 600, two with 401-600, five with 201-400, and four with ≤ 200 beds) in Japan from January to December 2022. The SAB management quality was evaluated using the SAB-QI score (ranging from 0 to 13 points), which consists of 13 QIs (grouped into five categories) based on previous literature. RESULTS: Of the 4,448 positive blood culture episodes, 289 patients with SAB (6.5%) were enrolled. The SAB-QI scores ranged from 3 to 13, with a median score of 9 points. The SAB-QI score was highest in middle-sized hospitals with 401-600 beds. Adherence to each of the four QI categories (blood culture, echocardiography, source control, and antibiotic treatment) was significantly higher in survived cases than in fatal cases. Kaplan-Meier curves with log-rank tests demonstrated that higher adherence to SAB-QIs indicated a better prognosis. Logistic regression analysis revealed that age, methicillin resistance, multiple comorbidities (≥ 2), and low SAB-QI score were significantly associated with 30-day mortality in patients with SAB. CONCLUSIONS: Our study highlights that greater adherence to the SAB-QIs correlates with improved patient outcomes. Management of patients with SAB should follow these recommended indicators to maintain the quality of care, especially for patients with poor prognosticators.

A 55-year-old male presented with abdominal pain that had begun about 5 days ago. Physical examination revealed oral aphtha, genital aphthosis, and pseudofolliculitis, and the patient was diagnosed with incomplete Behçet's disease (BD). Contrast-enhanced computed tomography (CECT) showed dilation of the superior mesenteric artery and mesenteric infiltration of inflammation, indicating vasculo-BD. The symptoms were improved by 3-day of intravenous methylprednisolone pulse therapy followed by oral prednisolone. A literature review suggested that vasculo-BD should be included as a differential diagnosis in cases with unexplained abdominal pain, arterial dilation, and mesenteric invasion, and CECT examination and steroid therapy should be considered.

We previously developed a novel method for gene transfer, which combined a non-viral gene expression vector with transcutaneous in vivo electroporation. We applied this method to transfer the bone morphogenetic protein (BMP) gene and induce ectopic bone formation in rat skeletal muscles. At present, it remains unclear which types of cells can differentiate into osteogenic cells after BMP gene transfer by in vivo electroporation. Two types of stem cells in skeletal muscle can differentiate into osteogenic cells: muscle-derived stem cells, and bone marrow-derived stem cells in the blood. In the present study, we transferred the BMP gene into rat skeletal muscles. We then stained tissues for several muscle-derived stem cell markers (e.g., Pax7, M-cadherin), muscle regeneration-related markers (e.g., Myod1, myogenin), and an inflammatory cell marker (CD68) to follow cell differentiation over time. Our results indicate that, in the absence of BMP, the cell population undergoes muscle regeneration, whereas in its presence, it can differentiate into osteogenic cells. Commitment towards either muscle regeneration or induction of ectopic bone formation appears to occur five to seven days after BMP gene transfer.

We experienced a case of scheduled cesarean section under spinal anesthesia in a patient with LAM which had been missed in spite of preoperative medical examination and consultation with specialists but discovered because of perioperative hypoxia A 35-year-old woman, Gravida 1 Para 0, with breech presentation was scheduled to undergo cesarean section under spinal anesthesia at 38 weeks of gestation. She had no history of asthma or abnormal findings at annual medical examination. She had suffered from dry cough and nocturnal dyspnea for 7 weeks and an inhaled bronchodilator was administered with diagnosis of inflammatory airway disease by her respiratory physicians. Spinal anesthesia was performed with bupivacaine 12.5 mg. At the beginning of anesthesia SPO2 was 97% in supine position, but it rapidly decreased to less than 90% and 3 l x min(-1) oxygen was supplied with a facial mask. The anesthetic level was thoracal 4 bilaterally and her breathing was stable. The circulatory state, Apgar score and other vital signs were within normal ranges. Postoperative chest X-ray showed bilateral numerous grained spots and computed tomography scans showed multiple thin-walled cysts. The characteristic history and the fluoroscopic data gave her clinical diagnosis of LAM.

Spontaneous pneumothorax is rare during pregnancy. A case of spontaneous pneumothorax occurring at 34 weeks' gestation in a healthy 25-year-old primigravida is described. Its occurrence was accompanied by sudden onset of dyspnea and pleuritic chest pain while the patient was walking. Diagnosis was made by chest radiograph and treatment was by tube thoracostomy. At 41 weeks' gestation, after normal labor progression, she successfully gave birth to a male infant with a birth weight of 2,744 g. We discuss spontaneous pneumothorax during pregnancy and review the literature.
