Intimal sarcoma of the pulmonary artery is rare, but false diagnosis of this sarcoma as pulmonary embolism is not infrequent. The present study reports a case of pulmonary artery intimal sarcoma misdiagnosed as pulmonary artery embolism in a 37-year-old female patient. The patient was admitted to the cardiac intensive care unit of Guangdong General Hospital (Guangzhou, China) with the complaint of progressive exertional dyspnea over the past two years. Multi-slice spiral computed tomography, transthoracic echocardiography, right-heart catheterization and cardiac magnetic resonance imaging revealed mimicking severe pulmonary embolism in the pulmonary trunk and right pulmonary artery, with symptoms including chest pain, cough and breathing difficulties...

High levels of CO2 emissions in the atmosphere and toxic pollutants in air, water and food have serious repercussions on all life's systems, including living beings, environment and economy. Everyone on the Earth is concerned by pollution in some way or another, no matter where and how the pollution is produced as airborne and foodborne pollutants could circulate around the world in different ways, through for example climate components (wind, rain) and/or import and export of foodstuffs. Similarly to living beings that take advantage of day-night circadian rhythms to recover after diurnal hardships, the environment in its entirety could also be seen as a complex living system that needs regular breaks to assimilate or ingest toxic pollutants produced during intensive and continuous industrial processes...

Reasoning with conditionals is central to everyday life, yet there is long-standing disagreement about the meaning of the conditional. One example is the puzzle of so-called missing-link conditionals such as "if raccoons have no wings, they cannot breathe under water." Their oddity may be taken to show that conditionals require a connection between antecedent ("raccoons have no wings") and consequent ("they cannot breathe under water"), yet most accounts of conditionals attribute the oddity to natural-language pragmatics...

Dissolved oxygen (DO) at cathodic interface is a critical factor influencing microbial fuel cells (MFC) performance. In this work, three MFCs were operated with cathode under different DO conditions: i) air-breathing (A-MFC); ii) water-submerged (W-MFC) and iii) assisted by photosynthetic microorganisms (P-MFC). A plateau of maximum current was reached at 1.06±0.03mA, 1.48±0.06mA and 1.66±0.04mA, increasing respectively for W-MFC, P-MFC and A-MFC. Electrochemical and microbiological tools (Illumina sequencing, confocal microscopy and biofilm cryosectioning) were used to explore anodic and cathodic biofilm in each MFC type...

Lung Clearance Index (LCI) provides an overall measurement of ventilation inhomogeneity. This population-based study examines whether LCI predicts pulmonary obstruction and incidence of chronic obstructive pulmonary disease (COPD) events over a long-term follow-up. Multiple breath nitrogen washout and spirometry were performed in 674 men from the cohort "Men born in 1914" at age 55 years. Subjects were classified into quartiles (Q) of LCI and according to LCI above and below upper limit of normal (ULN). Incidence of COPD events (COPD hospitalisations or COPD-related deaths) were monitored over the remaining life span of the men, by linkage with national hospital registers...

The rarity and non-specific symptoms of benign primary tracheal tumors always leaded to misdiagnosis and delayed treatment, and also undefined the optimal treatment. In this case, a 45-year-old woman had a history of progressive shortness of breath and dry cough for several years, CT scan revealed an intra-luminal tracheal mass invaded the left side of tracheal wall. After being located by bronchoscope preoperatively, the tumor was removed by surgical resection. The tumor was 1.5 cm in diameter with intact capsule...

Aims: Alcohol is a risk factor for cardiac arrhythmias. Retrospective analyses suggest supraventricular arrhythmias consecutive to acute alcohol consumption, but prospective data are limited. We intended to prospectively associate acute alcohol consumption with cardiac arrhythmias. Methods and results: At the 2015 Munich Octoberfest, we enrolled 3028 voluntary participants who received a smartphone-based ECG and breath alcohol concentration (BAC) measurements. ECGs were analysed for cardiac arrhythmias (sinus tachycardia, sinus arrhythmia, premature atrial/ventricular complexes, atrial fibrillation/flutter) and respiratory sinus arrhythmia...

BACKGROUND: In children, postoperative respiratory rate (RR) monitoring by transthoracic impedance (TI), capnography, and manual counting has limitations. The rainbow acoustic monitor (RAM) measures continuous RR noninvasively by a different methodology. Our primary aim was to compare the degree of agreement and accuracy of RR measurements as determined by RAM and TI to that of manual counting. Secondary aims include tolerance and analysis of alarm events. METHODS: Sixty-two children (2-16 years old) were admitted after tonsillectomy or receiving postoperative patient/parental-controlled analgesia...

: Chemicals are ubiquitous in the food we eat, the water we drink, the air we breathe, and the products we use at work and in our personal lives. Toxic chemicals increase the risk of cognitive, behavioral, and neurodevelopmental disorders throughout the life span. The Toxic Substances Control Act of 1976 was intended to allow for the collection of data on and regulation of these chemicals but has been criticized for its significant limitations in protecting the public's health. In recognition of the scientific evidence demonstrating the connection between toxic environmental chemicals and neurodevelopmental disorders, Project TENDR (Targeting Environmental Neuro-Developmental Risks)-a collaborative initiative of scientists, health professionals, and children's health advocates-produced a call to action last July with the aim of reducing exposure to chemicals and pollutants that contribute to the development of these disorders...

BACKGROUND: The Edmonton Symptom Assessment System-revised (ESAS-r) is a nine-item self-report symptom intensity tool developed for palliative care patients, with the option of adding a 10th patient-specific symptom. Due to growing international uptake, the ESAS-r has been translated into different languages. There has not been agreement, however, regarding a standard process for translation into multiple languages, which also includes patients' perspectives. OBJECTIVE: The purpose of this study was to develop a French version of the ESAS-r, using a standardized translation protocol, and to obtain palliative care patients' perspectives regarding this translated tool...

Kun-Ze Lee, Shih-Hui Hsu
Unilateral high cervical spinal hemisection (i.e., C2Hx) interrupts the respiratory bulbospinal pathway and results in paralysis of the hemidiaphragm. The ipsilateral diaphragmatic activity can partially recover over weeks to months; however, its contribution to the tidal volume generation is less than 20 %. Accordingly, we hypothesized that the contralateral diaphragm exert a compensatory function to maintain the essential ventilation following cervical spinal cord hemisection. The cardiorespiratory pattern and bilateral diaphragm electromyogram (EMG) were measured in urethane-anesthetized and spontaneously breathing adult rats at 1 day, 2 or 8 weeks post-C2Hx or C2 laminectomy...

BACKGROUND: The point of entry of a patient in emergency care is a symptom or a complaint. To evaluate subsequent processes in an emergency department until a diagnosis is made, this information has to be taken into account. OBJECTIVES: We report the introduction of coded presenting complaints into the electronic medical record system of an emergency department and describe the patients based on these data. METHODS: The CEDIS presenting complaint list was integrated into the emergency department information system of an emergency department (38,000 patients/year)...

REVIEW
Gilles Duvoisin, Usha Krishnan
Oesophageal atresia and tracheoesophageal fistula (OA-TOF) are a multifaceted condition which affects patients throughout their lives. Even though it is one of the most common gastrointestinal malformations, most of the current studies focus on gastro-oesophageal reflux disease, anastomotic strictures, and feeding difficulties. However, there is increasing evidence that a proportion of patients with OA-TOF also have abnormal gastric function. This review aims to provide a comprehensive understanding of studies of gastric function in patients with OA-TOF...
