Respiratory rates and patterns were studied in 23 patients with acute brain stem infarction using impedance pneumography. Autopsy was obtained in six of eight fatal cases. Pontine lesions were present in all patients, with coexistent infarction of midbrain in four and of medulla in nine. Respiratory rate and pattern abnormalities observed included(More)
OBJECTIVE Acute heart failure (AHF) is associated with high mortality and morbidity. Trimethylamine N-oxide (TMAO), a gut-derived metabolite, has reported association with mortality risk in chronic HF but this association in AHF is still unknown. The present study investigated TMAO in patients admitted to hospital with AHF, and association of circulating(More)
Cerebrospinal fluid (CSF) abnormalities were correlated with pathological diagnoses in 61 patients with autopsy-verified intracerebral hemorrhage or cerebral infarction. Lumbar punctures were performed within one week of onset of symptoms. The CSF color and red blood cell counts were the most useful CSF parameters in differentiating between intracerebral(More)
Acute cardiothoracic and respiratory diseases frequently remain a challenge to diagnose and differentiate in the emergency setting. The main diseases that manifest with chest pain include ischaemic heart disease, myocarditis, acute pericarditis, aortic dissection/rupture and pulmonary embolism (PE). Diseases that primarily present with dyspnoea include(More)
To determine the effect of inhaled carbon dioxide on acute ischemic cerebral injury, we have compared occipital visual evoked responses (VER) at baseline and during hypercapnia in 20 patients with acute unilateral cerebral infarction (ten with and ten without homonymous hemianopsia) and in ten normal controls. Visual evoked responses were judged on the(More)
The human foot provides an ideal environment for the colonization and growth of bacteria and subsequently is a body site associated with the liberation of odour. This study aimed to enumerate and spatially map bacterial populations' resident across the foot to understand any association with odour production. Culture-based analysis confirmed that(More)
Ventilatory and heart-rate responses to hypercapnia were evaluated by a CO2 rebreathing technique in 56 patients with acute ischemic stroke and 14 normal controls. Both ventilatory and heart-rate responses were increased in patients with hemispheral lesions, but not in patients with brainstem lesions. In patients with hemispheral infarct, there was a(More)
BACKGROUND B-type natriuretic peptide (BNP) molecular forms 5-32, 4-32, and 3-32 are known to be present in the circulation of heart failure (HF) patients. This study investigated the prognostic role of circulating BNP molecular forms on risk prediction for patients with acute HF. METHODS BNP molecular forms were measured in plasma using an immunocapture(More)

This study evaluates physiologic monitoring as a tool for improved nursing observation of acute stroke patients. Forty-four patients admitted within 48 hours of onset of stroke were monitored using an automated arrhythmia detection system and impedance pneumography. Cardiac arrhythmias were observed in 25 of 44 patients. Three patients with episodes of(More)
