Utilization and outcomes of life-supporting interventions in older ICU patients in Japan: a nationwide registry study.

Purpose: The purpose of this study is to describe the implementation of life-supporting interventions and the short-term outcomes of older patients in ICUs in Japan.

Methods: All adult patients admitted to ICUs participating in the Japanese Intensive Care Patient Database (JIPAD) from April 1, 2015, to March 31, 2022, were eligible for inclusion. Information, including life-supporting interventions, was retrieved from the database.

Orexin concentrations and diurnal variation in the cerebrospinal fluid of intensive care unit patients undergoing aortic surgery with spinal drainage.

Background: Cerebrospinal fluid (CSF) levels of orexin show a cyclic diurnal variation in healthy subjects, which is diminished in patients with certain diseases. However, possible circadian variations in orexin levels in critically ill patients remain unknown. In this study, we evaluated the orexin concentrations in the CSF and their diurnal variation in patients undergoing thoracic aortic aneurysm repair with lumbar intrathecal catheterization for CSF drainage after non-neurosurgery.

Naldemedine is associated with earlier defecation in critically ill patients with opioid-induced constipation: A retrospective, single-center cohort study.

Introduction: There are few reports describing the association of naldemedine with defecation in critically ill patients with opioid-induced constipation. The purpose of this study was to determine whether naldemedine is associated with earlier defecation in critically ill patients with opioid-induced constipation.

Methods: In this retrospective cohort study, patients admitted to the Intensive Care Unit (ICU) without defecation for 48 hours while receiving opioids were eligible for enrollment.

Respiratory support strategy in adults with acute hypoxemic respiratory failure: a systematic review and network meta-analysis.

Introduction: Network meta-analyses (NMAs) of respiratory management strategies for acute hypoxemic respiratory failure (AHRF) have been reported, but no previous study has compared noninvasive ventilation (NIV), high-flow nasal oxygen (HFNO), standard oxygenation therapy (SOT), and invasive mechanical ventilation (IMV) for de novo AHRF. Therefore, we conducted an NMA to assess the effectiveness of these four respiratory strategies in patients with de novo AHRF.

Methods: The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, and Ichushi databases were searched.

Association between timing of speech and language therapy initiation and outcomes among post-extubation dysphagia patients: a multicenter retrospective cohort study.

Background: Post-extubation dysphagia (PED) is recognized as a common complication in the intensive care unit (ICU). Speech and language therapy (SLT) can potentially help improve PED; however, the impact of the timing of SLT initiation on persistent PED has not been well investigated. This study aimed to examine the timing of SLT initiation and its effect on patient outcomes after extubation in the ICU.

Efficacy of non-invasive and invasive respiratory management strategies in adult patients with acute hypoxaemic respiratory failure: a systematic review and network meta-analysis.

Background: Although non-invasive respiratory management strategies have been implemented to avoid intubation, patients with de novo acute hypoxaemic respiratory failure (AHRF) are high risk of treatment failure. In the previous meta-analyses, the effect of non-invasive ventilation was not evaluated according to ventilation modes in those patients. Furthermore, no meta-analyses comparing non-invasive respiratory management strategies with invasive mechanical ventilation (IMV) have been reported.

Suvorexant is associated with a low incidence of delirium in critically ill patients: a retrospective cohort study.

Background: Benzodiazepine use is a risk factor for the development of delirium in adult intensive care unit (ICU) patients. Suvorexant is an alternative to benzodiazepines to induce sleep, but the incidence of delirium in critically ill patients is unknown. We undertook this retrospective study to investigate the incidence of delirium in patients who receive suvorexant in the ICU.

Interruption of enteral nutrition in the intensive care unit: a single-center survey.

Background: Interruption of enteral nutrition (EN) in the intensive care unit (ICU) occurs frequently for various reasons including feeding intolerance and the conduct of diagnostic and therapeutic procedures. However, few studies have investigated the details of EN interruption practices including reasons for and duration of interruptions. There is no standard protocol to minimize EN interruptions.

[Autopsy case of light chain deposition disease presented by nephrotic syndrome].

An eighty-one-year-old male with lower leg edema and proteinuria was diagnosed as having nephrotic syndrome and was hospitalized for a detailed examination. Kidney biopsy and immunostaining revealed nodular glomerulosclerosis and deposition of lambda chains, respectively. Because these findings indicate the occurrence of light chain deposition disease (LCDD), the underlying disease was found to be multiple myeloma BJ-lambda.

Effect of pH and addition of salt on the adsorption behavior of lysozyme on gold, silica, and titania surfaces observed by quartz crystal microbalance with dissipation monitoring.

The adsorption behaviors of lysozyme on dentally related Au, SiO2, and TiO2 surfaces were investigated by a quartz crystal microbalance with dissipation monitoring (QCM-D) method. Frequency shifts indicated that while lysozyme (pI 11) was fairly adsorbed on the SiO2 (pI 1.9) surface at both pH 3 and 7, it was adsorbed on TiO2 (pI 6.
