BACKGROUND: A simple technique to measure dynamic hyperinflation (DH) in patients with chronic obstructive pulmonary disease (COPD) is the metronome-paced tachypnea test (MPT). Earlier studies show conflicting results about the accuracy of the MPT compared to cardiopulmonary exercise testing (CPET). OBJECTIVES: The focus was to investigate the diagnostic accuracy of MPT to detect DH in a prospective and clinical study. METHODS: COPD patients were included; all underwent spirometry, CPET, and MPT...

BACKGROUND: Scrub typhus, caused by Orientia tsutsugamushi, is a major cause of acute febrile illness in children in the rural tropics. METHODS: We recruited 60 febrile pediatric patients with a positive scrub typhus rapid diagnostic test result and 40 healthy controls from Chiang Rai Province in northern Thailand. Diagnosis was confirmed by the detection of (1) O. tsutsugamushi-specific DNA in blood or eschar samples with a polymerase chain reaction assay, (2) a fourfold rise in immunoglobulin M (IgM) titer to ≥1:3200 in paired plasma samples with an indirect immunofluorescence assay (IFA), or (3) a single IgM titer of ≥1:3200 in an acute plasma sample with an IFA...

BACKGROUND: Myocarditis is an important cause of morbidity and mortality in children, leading to long-term sequelae including chronic congestive heart failure, dilated cardiomyopathy, heart transplantation, and death. The initial diagnosis of myocarditis is usually based on clinical presentation, but this widely ranges from the severe sudden onset of a cardiogenic shock to asymptomatic patients. Early recognition is essential in order to monitor and start supportive treatment prior to the development of severe adverse events...

BACKGROUND: Compared with vaginal delivery, early-term cesarean section (CS) is associated with an increased risk of neonatal respiratory morbidity. Given the role of steroids in lung maturation in preterm labor, few studies have investigated their effects on early-term delivery. Therefore, this study aimed to investigate the effect of antenatal betamethasone on neonatal respiratory morbidity in early-term elective cesarean (37-38 weeks and 6 d). METHODS: This randomized clinical trial was conducted in Mahdieh Hospital in Tehran in 2017...

Acoustic respiratory rate (RRa) monitoring is a non-invasive method of monitoring respiratory rate in spontaneously breathing individuals. The aim of this report is to highlight the clinical utility of this monitoring system in post-thyroidectomy patients by presenting a case of respiratory compromise due to post-thyroidectomy hematoma, in which the alarm of the respiratory rate monitor alerted the nursing staff about the complication. A 61-year-old woman who uneventfully underwent right thyroid lobectomy for adenomatous goiter under general anesthesia with endotracheal intubation was being monitored postoperatively using the RRa monitoring system...

BACKGROUND: Rebound cholinergic syndrome is a rare, but well known unwanted phenomenon occurring after abrupt clozapine discontinuation. There have been previous reported cases of cholinergic rebound in the literature; however, these reports described cholinergic rebound following cessation of high doses of clozapine in patients diagnosed with schizophrenia. Here, we report a case of rebound cholinergic syndrome and catatonia in a male patient three days after abrupt discontinuation of 50 mg of clozapine prescribed for type I bipolar affective disorder...

BACKGROUND: The risk for transient tachypnea of newborns, a common cause of respiratory distress in the neonatal period, is 2- to 6-fold higher during elective cesarean delivery compared to vaginal delivery. Here, we evaluated the association between transient tachypnea of newborns and the degree and duration of predelivery maternal hypotension during spinal anesthesia for elective cesarean delivery. METHODS: Demographic data, details of anesthetic management, blood pressure measurements, and vasopressor requirement preceding delivery were compared between transient tachypnea newborns (n = 30) and healthy neonates (n = 151) with normal respiratory function born via elective cesarean delivery between July 2015 and February 2016...

Multiple crosstalk between peripheral organs and the nervous system are required to maintain physiological and metabolic homeostasis. Using Vav3-deficient mice as a model for chronic sympathoexcitation-associated disorders, we report here that afferent fibers of the hepatic branch of the vagus nerve are needed for the development of the peripheral sympathoexcitation, tachycardia, tachypnea, insulin resistance, liver steatosis and adipose tissue thermogenesis present in those mice. This neuronal pathway contributes to proper activity of the rostral ventrolateral medulla, a sympathoregulatory brainstem center hyperactive in Vav3-/- mice...

Heart failure with reduced ejection fraction (HFREF) increases neutral sphingomyelinase (NSMase) activity, mitochondrial reactive oxygen species emission (ROS), and causes diaphragm weakness. We tested whether a systemic pharmacologic NSMase inhibitor or short-hairpin RNA (shRNA) targeting NSMase isoform 3 (NSMase3) would prevent diaphragm abnormalities induced by HFREF caused by myocardial infarction. In the pharmacological intervention, we used intraperitoneal injection of GW4869 or vehicle. In the genetic intervention, we injected adeno-associated virus serotype 9 (AAV9) containing targeting NSMase3 or a scrambled sequence directly into the diaphragm...

Diabetes affects approximately 30 million persons in the United States. Diabetes ketoacidosis is one of the most serious and acute complications of diabetes. At the time of presentation and during treatment of diabetic ketoacidosis (DKA), several metabolic and electrolyte derangements can ultimately result in respiratory compromise. Most commonly, hypokalemia, hypomagnesemia and hypophosphatemia can eventually lead to respiratory muscles failure. Furthermore, tachypnea, hyperpnea and more severely, Kussmaul breathing pattern can develop...
