Evaluation of the Impact of ABCDEF Bundle Compliance Rates on Postintensive Care Syndrome: A Secondary Analysis Study.

OBJECTIVES: This study aimed to examine the association between ABCDEF bundles and long-term postintensive care syndrome (PICS)-related outcomes. DESIGN: Secondary analysis of the J-PICS study. SETTING: This study was simultaneously conducted in 14 centers and 16 ICUs in Japan between April 1, 2019, and September 30, 2019. PATIENTS: Adult ICU patients who were expected to be on a ventilator for at least 48 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Bundle compliance for the last 24 hours was recorded using a checklist at 8:00 am The bundle compliance rate was defined as the 3-day average of the number of bundles performed each day divided by the total number of bundles. The relationship between the bundle compliance rate and PICS prevalence (defined by the 36-item Short Form Physical Component Scale, Mental Component Scale, and Short Memory Questionnaire) was examined. A total of 191 patients were included in this study. Of these, 33 patients (17.3%) died in-hospital and 48 (25.1%) died within 6 months. Of the 96 patients with 6-month outcome data, 61 patients (63.5%) had PICS and 35 (36.5%) were non-PICS. The total bundle compliance rate was 69.8%; the rate was significantly lower in the 6-month mortality group (66.6% vs 71.6%, p = 0.031). Bundle compliance rates in patients with and without PICS were 71.3% and 69.9%, respectively ( p = 0.61). After adjusting for confounding variables, bundle compliance rates were not significantly different in the context of PICS prevalence ( p = 0.56). A strong negative correlation between the bundle compliance rate and PICS prevalence ( r = -0.84, R 2 = 0.71, p = 0.035) was observed in high-volume centers. CONCLUSIONS: The bundle compliance rate was not associated with PICS prevalence. However, 6-month mortality was lower with a higher bundle compliance rate. A trend toward a lower PICS prevalence was associated with higher bundle compliance in high-volume centers.

Lidocaine as a potential therapeutic option for super-refractory status epilepticus: A case report.

New-onset refractory status epilepticus (NORSE) is a rare and devastating condition and the prognosis is often poor, with half to two-thirds of survivors experiencing drug-resistant epilepsy, residual cognitive impairment, or functional disability, and the mortality rate is 16% to 27% for adults. We describe a patient with cryptogenic NORSE and favorable recovery from drug-resistant super-refractory SE after the use of intravenous lidocaine. The patient experienced fever and presented with refractory generalized tonic-clonic seizures. The cause was not found by performing extensive examinations, including cell surface autoantibodies and rat brain immunohistochemistry evaluations. The refractory SE with unresponsiveness to multiple anti-epileptic and prolonged sedative medications, which are necessary for prolonged mechanical ventilation, were ameliorated by additive treatment with intravenous lidocaine initiating at 1 mg/kg/h and maintaining at 2 mg/kg/h for 40 days, which led to freedom from intravenous sedative medication and mechanical ventilation. The patient was able to return to school. Lidocaine may be an optional treatment for cryptogenic NORSE.

The Efficacy of Acute Myocardial Infarction Intensive Care Unit Management with a Collaborative Intensivists and Cardiologists in Japan: A Retrospective Observational Study.

Objective Dedicated intensive care unit (ICU) physician staffing is associated with a reduction in ICU mortality rates in general medical and surgical ICUs. However, limited data are available on the role of intensivists in ICU for cardiac disease, especially in Japan. This study investigated the association of collaborative intensivists and cardiologist care with clinical outcomes in patients with acute myocardial infarction (AMI) admitted to the ICU. Methods This study analyzed 106 patients admitted to the ICU at Nara Prefecture General Medical Center in Nara, Japan, from April 2017 to April 2019. Eligible patients were divided into either the high-intensity ICU management group (n=51) or the low-intensity ICU management group (n=55). The primary outcome of in-hospital mortality was compared in the two groups. Results The high-intensity ICU group was found to be associated with a lower mortality rate in a multivariate analysis than the low-intensity group [7.8% vs. 16.4%; odds ratio (OR): 0.07; 95% confidence interval (CI): 0.01-0.54; p=0.01]. There were no significant differences in the length of either the ICU stay or hospital stay or the hospital costs between the two groups. A subgroup analysis revealed that the in-hospital mortality rate was lower in the high-intensity ICU group than in the low-intensity ICU group among patients with Killip class IV (16.7% vs. 34.6%; OR, 0.08; 95% CI, 0.01-0.67; p=0.02). Conclusion The presence of dedicated intensivists in high-intensity ICU collaborating with cardiologists might reduce in-hospital mortality in patients with Killip class IV AMI who require critical care.

Concomitant acute pulmonary embolism, myocardial infarction and ischemic stroke due to paradoxical embolism from a patent foramen ovale: a case report.

A patent foramen ovale (PFO) is a cause of paradoxical embolism. Although most patients with a PFO are asymptomatic, various clinical manifestations may be associated with PFO. The most important is a cryptogenic stroke. Concomitant acute pulmonary embolism (APE), acute myocardial infarction (AMI) and acute ischemic stroke (AIS) due to paradoxical embolism from a PFO are extremely rare. We describe a 77-year-old woman with a past medical history of hypertension who was transferred due to a sudden onset of dyspnea followed by cardiopulmonary arrest. Based on the patient's medical history, transthoracic and transesophageal echocardiography, coronary angiography, and a whole-body contrasted computed tomography, we diagnosed concomitant APE, AMI and AIS caused by a paradoxical embolism from a PFO. Appropriate knowledge of the pathophysiology of this rare critical illness is important for prompt diagnosis and treatment.

Early detection of large-vessel occlusion stroke after cardiac surgery using CT angiography leading to early recanalization with endovascular thrombectomy.

CT angiography may be useful for early diagnosis of ischemic stroke after cardiac surgery. When patients diagnosed with large-vessel occlusion, endovascular thrombectomy may be a therapeutic option and may improve their neurological complications.

Prevalence of post-intensive care syndrome among Japanese intensive care unit patients: a prospective, multicenter, observational J-PICS study.

BACKGROUND: Many studies have compared quality of life of post-intensive care syndrome (PICS) patients with age-matched population-based controls. Many studies on PICS used the 36-item Short Form (SF-36) health survey questionnaire version 2, but lack the data for SF-36 values before and after intensive care unit (ICU) admission. Thus, clinically important changes in the parameters of SF-36 are unknown. Therefore, we determined the frequency of co-occurrence of PICS impairments at 6 months after ICU admission. We also evaluated the changes in SF-36 subscales and interpreted the patients' subjective significance of impairment. METHODS: A prospective, multicenter, observational cohort study was conducted in 16 ICUs across 14 hospitals in Japan. Adult ICU patients expected to receive mechanical ventilation for > 48 h were enrolled, and their 6-month outcome was assessed using the questionnaires. PICS definition was based on the physical status, indicated by the change in SF-36 physical component score (PCS) ≥ 10 points; mental status, indicated by the change in SF-36 mental component score (MCS) ≥ 10 points; and cognitive function, indicated by the worsening of Short-Memory Questionnaire (SMQ) score and SMQ score at 6 months < 40. Multivariate logistic regression model was used to identify the factors associated with PICS occurrence. The patients' subjective significance of physical and mental symptoms was assessed using the 7-scale Global Assessment Rating to evaluate minimal clinically important difference (MCID). RESULTS: Among 192 patients, 48 (25%) died at 6 months. Among the survivors at 6 months, 96 patients responded to the questionnaire; ≥ 1 PICS impairment occurred in 61 (63.5%) patients, and ≥ 2 occurred in 17 (17.8%) patients. Physical, mental, and cognitive impairments occurred in 32.3%, 14.6% and 37.5% patients, respectively. Population with only mandatory education was associated with PICS occurrence (odds ratio: 4.0, 95% CI 1.1-18.8, P = 0.029). The MCID of PCS and MCS scores was 6.5 and 8.0, respectively. CONCLUSIONS: Among the survivors who received mechanical ventilation, 64% had PICS at 6 months; co-occurrence of PICS impairments occurred in 20%. PICS was associated with population with only mandatory education. Future studies elucidating the MCID of SF-36 scores among ICU patients and standardizing the PICS definition are required.

Infected thoracoabdominal aortic aneurysm related to an implanted long-term arterial catheter for chemotherapy: a case report.

BACKGROUND: An infected aortic aneurysm is a rare and life-threatening vascular condition with a high incidence of arterial rupture and recurrence even after treatment. One of the most common causes of an infected aortic aneurysm is catheter-related bloodstream infection. Although infection due to indwelling catheters is possible, the incidence of this is rare, especially for long-term implanted arterial catheters. CASE PRESENTATION: A 78-year-old Japanese man with a past medical history of rectal cancer with metastasis to the liver presented to our hospital as a result of low back pain. Remission had been achieved following surgery and adjuvant chemotherapy via an implanted catheter for arterial infusion. However, the original catheter that was inserted from the femoral artery to the hepatic artery via the celiac artery was still present more than 10 years after diagnosis, without being replaced, in case of a recurrence. On the day of admission, computed tomography scan of the chest and abdomen with contrast revealed an irregularly shaped aortic aneurysm at the origin of the celiac artery and a partially expanded common hepatic artery with disproportionate fat stranding along the implanted arterial catheter without extravasation. Although the initial impression was an impending rupture of the acute thoracoabdominal aortic aneurysm, a catheter-related infection was considered as a differential diagnosis. Surgery was performed, which revealed a catheter-related infected aortic aneurysm based on images along the catheter, pus cultures, and tissue pathology examination results. CONCLUSIONS: This is an extremely rare case of an infectious aneurysm caused by prolonged implantation of an arterial catheter for chemotherapy. It should be noted that an indwelling arterial catheter not only causes bloodstream infections but can also cause an infection of a thoracoabdominal aortic aneurysm.

Low systolic blood pressure on admission predicts mortality in patients with acute decompensated heart failure due to moderate to severe aortic stenosis.

BACKGROUND: We investigated the relationship between admission systolic blood pressure (SBP) and all-cause mortality in patients hospitalized for acute decompensated heart failure (ADHF) because of aortic stenosis (AS). METHODS AND RESULTS: We retrospectively reviewed the data for 71 consecutive patients (mean age 85±7 years) who had been hospitalized for ADHF because of AS between January 2006 and August 2012. The primary endpoint of the study was the 1-year all-cause mortality. Clinical outcomes of patients who survived and those who died during a 1-year period were compared. Low admission SBP was defined as <120 mmHg. During the 1-year period, 26 (37%) of the 71 patients died, including 16 (57%) of 28 patients with low SBP and 10 (23%) of 43 patients with normal or high SBP (log-rank P=0.0065). In both the patients who survived and those who died, there were significant differences in admission SBP (152±43 vs. 116±32 mmHg, P<0.001), estimated glomerular filtration rate on admission (43.2±20.3 vs. 28.2±22.2 ml·min(-1)·1.73 m(-2), P=0.005), and left ventricular ejection fraction <50% (33% [15/45] vs. 65% [17/26], P=0.013). Low admission SBP independently predicted 1-year all-cause mortality (adjusted hazard ratio: 2.41, 95% confidence interval: 1.04-5.57, P=0.033). CONCLUSIONS: Low admission SBP is associated with significantly higher 1-year all-cause mortality in patients hospitalized for ADHF because of AS.

Association between tissue characteristics evaluated with optical coherence tomography and mid-term results after paclitaxel-coated balloon dilatation for in-stent restenosis lesions: a comparison with plain old balloon angioplasty.

AIMS: Morphological assessment of neointimal tissue using optical coherence tomography (OCT) is important for clarifying the pathophysiology of in-stent restenosis (ISR) lesions. The aim of this study was to determine the impact of OCT findings on recurrence of ISR after paclitaxel-coated balloon (PCB) dilatation compared with plain old balloon angioplasty (POBA). METHODS AND RESULTS: Between July 2008 and May 2012, we performed percutaneous coronary intervention for 214 ISR lesions using POBA + PCB (146 lesions, PCB group) or POBA only (68 lesions, POBA group). Morphological assessment of neointimal tissue using OCT, including assessment of restenotic tissue structure and restenotic tissue backscatter, was performed. We examined the association between lesion morphologies and mid-term (6-8 months) results including ISR and target lesion revascularization (TLR) rates. Both ISR and TLR rates of lesions with a homogeneous structure were significantly lower in the PCB group than those in the POBA group (ISR: 20.0 vs. 55.6%, P = 0.002, TLR: 12.7 vs. 37.0%, P = 0.019), but there was no difference between the two groups in ISR and TLR rates of lesions with a heterogeneous or layered structure. Both ISR and TLR rates of lesions with high backscatter were significantly lower in the PCB group than those in the POBA group (ISR: 19.8 vs. 52.5%, P < 0.001, TLR: 13.6 vs. 42.5%, P = 0.001), but there was no difference between the two groups in ISR and TLR rates of lesions with low backscatter. CONCLUSION: Morphological assessment of ISR tissue using OCT might be useful for identifying ISR lesions favourable for PCB dilatation.

Trefoil factor 2 in gland mucous cell mucin in the mucous gel covering normal or damaged gastric mucosa using the Mongolian gerbil model.

OBJECTIVE: Trefoil factor 2 (TFF2) is localized in gastric gland mucous cells. The purpose of the study was to determine whether TFF2 and gastric mucin are localized in mucous cells and in the surface mucous gel layer (SMGL) of the normal gastric mucosa or in the mucoid cap adherent to gastric mucosal lesions in Mongolian gerbils. MATERIAL AND METHODS: Gastric mucosal lesions were induced in Mongolian gerbils using oral administration of Helicobacter pylori (H. pylori), subcutaneous administration of indomethacin, or oral administration of 30% ethanol. Tissue samples were fixed in Carnoy's solution for preservation of the SMGL, dehydrated, and embedded in paraffin. Histochemical staining for gastric mucins and immunostaining for TFF2 were performed. RESULTS: It was found that surface mucous cell mucin and gland mucous cell mucin were segregated in the SMGL covering the normal gastric mucosa, and the mucin of the mucoid cap covering the mucosal lesions was primarily gland mucous cell mucin. There was a co-localization of TFF2 in gland mucous cell mucin in gland mucous cells, the SMGL, and the mucoid cap. CONCLUSIONS: The co-localization of TFF2 in gland mucous cells and in the adherent mucus suggests a physical interaction between TFF2 and gland mucous cell mucin, and the participation of TFF2 trapped in the adherent mucus functions in mucosal defense, healing, and repair.
