BACKGROUND: We aimed to assess the relationship between echocardiographic characteristics and mortality in patients with chronic obstructive pulmonary disease (COPD). METHODS: We prospectively studied 154 patients (mean age 71 ± 10 years, 71% male) with COPD. All patients underwent transthoracic Doppler echocardiography within 48 hours of hospital admission. Primary endpoint was all-cause mortality during a median period of 22 months. RESULTS: Mildly elevated tricuspid regurgitation pressure and mitral E/e' ratio were the most commonly encountered echocardiographic abnormalities, observed in 60% and 56% of patients, respectively...

Mucopolysaccharidosis (MPS) type-IH is a lysosomal storage disease that results from mutations in the IDUA gene causing the accumulation of glycosaminoglycans (GAGs). Historically, children with the severe phenotype, MPS-IH (Hurler syndrome) develop progressive neurodegeneration with death in the first decade due to cardio-pulmonary complications. New data suggest that inflammation may play a role in MPS pathophysiology. To date there is almost no information on the pathophysiologic changes within the cerebral spinal fluid (CSF) of these patients...

Likely, maintained organ and notably cerebral perfusion, secures rapid recovery following anesthesia. To secure cerebral blood flow (CBF) at least mean arterial pressure (MAP) and the arterial carbon dioxide tension (PaCO2) need to be considered. CBF is "autoregulated", i.e. stays more or less stable within a MAP of 50-150 mmHg, but the lower limit appears to depend on the central blood volume and/or cardiac output, illustrated by a decrease in CBF at a MAP of 80 mmHg with a compromised central blood volume, while CBF remains constant with a MAP < 40 mmHg, if the central blood volume is maintained...

The detection limit for helium (He) partial pressure monitoring via the Penning discharge optical emission diagnostic, mainly used for tokamak divertor effluent gas analysis, is shown here to be possible for He concentrations down to 0.1% in predominantly deuterium effluents. This result from a dedicated laboratory study means that the technique can now be extended to intrinsically (non-injected) He produced as fusion reaction ash in deuterium-tritium experiments. The paper also examines threshold ionization mass spectroscopy as a potential backup to the optical technique, but finds that further development is needed to attain with plasma pulse-relevant response times...

We report the development of a versatile material preparation chain for intermetallic compounds, which focuses on the realization of a high-purity growth environment. The preparation chain comprises an argon glovebox, an inductively heated horizontal cold boat furnace, an arc melting furnace, an inductively heated rod casting furnace, an optically heated floating-zone furnace, a resistively heated annealing furnace, and an inductively heated annealing furnace. The cold boat furnace and the arc melting furnace may be loaded from the glovebox by means of a load-lock permitting to synthesize compounds starting with air-sensitive elements while handling the constituents exclusively in an inert gas atmosphere...

BACKGROUND: Using a restrictive transfusion strategy appears to be safe in sepsis, but there may be subgroups of patients who benefit from transfusion at a higher haemoglobin level. We explored if subgroups of patients with septic shock and anaemia had better outcome when transfused at a higher vs. a lower haemoglobin threshold. METHODS: In post-hoc analyses of the full trial population of 998 patients from the Transfusion Requirements in Septic Shock (TRISS) trial, we investigated the intervention effect on 90-day mortality in patients with severe comorbidity (chronic lung disease, haematological malignancy or metastatic cancer), in patients who had undergone surgery (elective or acute) and in patients with septic shock as defined by the new consensus definition: lactate above 2 mmol/l and the need for vasopressors to maintain a mean arterial pressure above 65 mmHg...

The authors aimed to compare the opening pressures of children with demyelinating disease to children with primary intracranial hypertension. Medical records were reviewed for a primary diagnosis of demyelinating disease, or primary intracranial hypertension. Diagnosis of demyelinating disease was made according to either the 2007 or 2012 International Pediatric Multiple Sclerosis Study Group criteria. Primary intracranial hypertension diagnosis was confirmed by presence of elevated opening pressure, normal cerebrospinal fluid composition and neuroimaging...

Previous clinical and elderly population studies have found that affective well-being can be assessed by clino-orthostatic cardiovascular reactivity. This study explored this relationship in a young healthy sample, and with respect to cognitive appraisals of well-being. Four successive readings of blood pressure (BP) and heart rate (HR) after lying down (clinostatic probe) followed by four successive readings after standing up (orthostatic probe) were obtained from 52 healthy students along with questionnaire-reported well-being...

OBJECTIVES: Hypertension is highly prevalent in West African populations, but little data is available on salt and potassium intake in these populations. We assumed in this study that sodium and potassium intake might be high and low, respectively, in the Beninese population in view of the emerging nutritional transition. The aim of this study was to estimate dietary sodium and potassium intakes based on 24-h urine collections. METHODS: We selected 420 individuals (ages 25-64 y), representative of the population, from urban and rural areas in Benin...

BACKGROUND: Studies have demonstrated an increased risk of cardiovascular disease (CVD)-associated death (CVD death) with increased resting heart rate (RHR); however, whether the association is consistent in rural Chinese with hypertension and normotension is unknown. We examined the association of RHR and CVD death by hypertension and normotension status in rural Chinese people. METHODS: Baseline data for 20,069 participants ≥18 years old were collected during July to August of 2007 and July to August of 2008; 17,151 (85...

REVIEW
John C Greenwood, Clinton J Orloski
Resuscitation goals for the patient with sepsis and septic shock are to return the patient to a physiologic state that promotes adequate end-organ perfusion along with matching metabolic supply and demand. Ideal resuscitation end points should assess the adequacy of tissue oxygen delivery and oxygen consumption, and be quantifiable and reproducible. Despite years of research, a single resuscitation end point to assess adequacy of resuscitation has yet to be found. Thus, the clinician must rely on multiple end points to assess the patient's overall response to therapy...

The incidence of traumatic spinal cord injury (SCI) has not changed much over the years due to an aging population suffering falls, yet advances have been made in quality of life and survival time. In addition to initial medical and surgical stabilization, modern intensive care unit (ICU) care throughout the critical early period following SCI is essential to avoid continued secondary injury to the spinal cord. Cervical SCI patients are particularly prone and sensitive to periods of cardiovascular instability and respiratory failure directly resulting from their injuries...

Two recently synthesized dihydropyrimidines (DHPMs) analogues have demonstrated larvicide and repellent activity against Anopheles arabiensis. DHPMs high lipophilicity suggests that these compounds may interact directly with the membrane and modify their biophysical properties. The purpose of the present study was to characterize the interaction of both compounds with artificial membranes. Changes on the properties of DPPC films were studied using Langmuir monolayers. The presence of DHPMs in the subphase modified the interfacial characteristics of DPPC compression isotherms, causing the expansion of the monolayer, inducing the disappearance of DPPC phase transition and increasing the molecular packing of the film...

Therapeutic hypercapnia has the potential for neuroprotection after global cerebral ischemia. Here we further investigated the effects of different degrees of acute systemic hypoxia in combination with hypercapnia on brain damage in a rat model of hypoxia and ischemia. Adult wistar rats underwent unilateral common carotid artery (CCA) ligation for 60 min followed by ventilation with normoxic or systemic hypoxic gas containing 11%O2,13%O2,15%O2 and 18%O2 (targeted to PaO2 30-39 mmHg, 40-49 mmHg, 50-59 mmHg, and 60-69 mmHg, respectively) or systemic hypoxic gas containing 8% carbon dioxide (targeted to PaCO2 60-80 mmHg) for 180 min...
