The symptoms of asthma, breathlessness, insomnia, etc. all have relevance to pulmonary rhythmic disturbances. Epidemiology and toxicology studies have demonstrated that exposure to ambient air particles can result in pulmonary dysfunction. However, there are no data directly supporting a link between air pollution and circadian rhythm disorder. In the present study, we found that breathing highly polluted air resulted in changes of the molecular clock genes expression in lung by transcriptome profiling analyses in a rodent model...

In the clinic, the wheezing sound is usually considered as an indicator symptom to reflect the degree of airway obstruction. The auscultation approach is the most common way to diagnose wheezing sounds, but it subjectively depends on the experience of the physician. Several previous studies attempted to extract the features of breathing sounds to detect wheezing sounds automatically. However, there is still a lack of suitable monitoring systems for real-time wheeze detection in daily life. In this study, a wearable and wireless breathing sound monitoring system for real-time wheeze detection was proposed...

BACKGROUND: Micrognathia is a congenital anomaly that may pose breathing and feeding limitations in newborns, sometimes necessitating invasive management. The present study aims to identify the complications associated with receiving mandibular surgery during the birth stay in order to better predict which patients may benefit from early surgical intervention. METHODS: A retrospective cohort study was performed using the 2000 to 2012 kids' inpatient databases. We included all live newborn infants born in the hospital through vaginal delivery or caesarean section...

Alzheimer's disease (AD) is known for the progressive decline of cognition and memory. In addition to these disease-defining symptoms, impairment of respiratory function is frequently observed and often expressed by sleep-disordered breathing or reduced ability to adjust respiration when oxygen demand is elevated. The mechanisms for this are widely unknown. Postmortem analysis from the brainstem of AD patients reveals pathological alterations, including in nuclei responsible for respiratory control. In this study, we analyzed respiratory responses and morphological changes in brainstem nuclei following intracerebroventricular (ICV) injections of streptozotocin (STZ), a rat model commonly used to mimic sporadic AD...

PURPOSE: Evidence shows that music therapy aids in symptom management and improves quality of life for palliative medicine and hospice patients. The majority of previous studies have addressed patient needs, while only a few addressed the needs of family members. The primary purpose of this study was to understand family members' perceptions of music therapy experienced by a relative in palliative medicine or hospice. Patient self-reported scales and music therapist assessment of change were also investigated...

Penicillium marneffei is a rare deep tissue fungal infection causing an endemic in Southeast Asia. This infection causes penicilliosis disease and is more common in patients who are immunocompromised. To date, no cases of P. marneffei infection relapse following treatment have been reported. A 36-year-old patient attended our hospital as a result of intermittent fever, cough, shortness of breath and multiple soft lesions located on the face, arms, neck and trunk. The medical radiological examination of the lung revealed multiple patchy exudative shadows, thick-walled hollow inner part of the visible lesions, bilateral pleural and pericardial effusion...

BACKGROUND: Pregnancy is a risk factor for sleep disordered breathing, including obstructive sleep apnea (OSA). Progesterone, one of the key hormones in pregnancy, a known respiratory drive stimulant, increases ventilation and may protect against OSA. We aimed to examine the relationship between circulating progesterone and OSA, after accounting for body weight and gestational age. METHODS: A case control study was conducted of pregnant women with OSA and those at low risk for the disorder...

Background Asthma control falls short of current goals of asthma management guidelines. Non-invasive monitoring of airway inflammation may help to improve the level of asthma control in children. Aim 1) To identify a set of exhaled volatile organic compounds (VOCs) that is most predictive for an asthma exacerbation in children. 2) To determine the chemical background of predictive VOCs. Methods In an one-year prospective observational study, 96 asthmatic children were studied . At clinical visits with an interval of 2 months, asthma control, fractional exhaled nitric oxide, lung function (FEV1, FEV1/VC) and VOCs in exhaled breath were determined by means of gas chromatography time-of-flight mass spectrometry...

Due to changes of discharge regime downstream of a dam reservoir, an alluvial natural stretch of the Warta River changed to a macrophyte-dominated ecosystem. Large patches of submersed, aquatic macrophytes appeared in summer and their effect is analysed in this study. These patches contained enriched macroinvertebrate assemblages (epiphyton and benthos) and they were refuge for both zooplankton and young fishes released from the reservoir. Despite these altered conditions in this stretch, roach Rutilus rutilus, perch Perca fluviatilis and ruffe Gymnocephalus cernua dominated, as they did in the natural backwater...

BACKGROUND: Dyspnea (breathing discomfort) is a common and distressing symptom. Routine assessment and documentation can improve management and relieve suffering. A major barrier to routine dyspnea documentation is the concern that it will have a deleterious effect on nursing workflow and that it will not be readily accepted by nurses. Nurses at our institution recently began to assess and document dyspnea on all medical-surgical patients upon admission and once per shift throughout their hospitalization...
