Rapid-onset obesity with hypoventilation, hypothalamic dysfunction and autonomic dysregulation (ROHHAD) syndrome is a rare disease that is difficult to diagnosis and distinguish from genetic obesity syndromes. The underlying causes of the disease has not been fully explained. Hypothalamic dysfunction causes endocrine problems, respiratory dysfunction and autonomic alterations. There are around 80 reported patients due to lack of recognition. We present two female patient suspected of ROHHAD due to weight gain since early childhood...

Sleep-disordered breathing (SDB) is characterized by repetitive episodes of decreased or arrested respiratory airflow during sleep. SDB is common and affects approximately 20% of the Japanese general population. Most traits of normal sleep and SDB show familial aggregation, suggesting significant effects of genetic factors. Obstructive sleep apnea (OSA) is the most common type of SDB and has a high heritability. Regardless of high heritability, no risk locus for OSA has reached a genome-wide level of significance (P < 5×10-8 ) in linkage or candidate gene analysis...

In metabolic diseases such as obesity, metabolic syndrome and type II diabetes, the over-expression of uncoupling proteins (UCPs) in a response to increased reactive oxygen species (ROS) generation by mitochondrial respiratory complexes, and to the excess of free fatty acid (FFA) supply from adipose tissue, may protect cells from oxidative stress, lipotoxicity and in turn from death. UCPs by reducing superoxide anion and H2O2 generation trigger several signals to cell for their adaptation to the lipotoxic microenvironment...

Mitochondrial malfunction is related to aging and to the onset of many diseases, such as obesity/diabetes, cancer, and cardiovascular and neurodegenerative diseases. The molecular principles of biological and toxicological processes the mitochondria can regulate should be disease-specific, cell type-specific, and drug targetable. Mitochondrial biology and toxicology is evolving and undergoing a revolution through fast-developing biotechnologies garnering increasing attention due to the importance of targeted therapies...

Many papers have been published investigating the effects of intraoperative mechanical ventilation on the incidence of intra- and postoperative respiratory complications. The potential advantages of protective pressure over volume-controlled ventilation mode during laparoscopic surgery have yet to be proven. This study included 60 patients aged between 18 and 70 with ASA score 1-3, body mass index (BMI) ≤35 kg/m2, and without prior history of chronic respiratory diseases, who were scheduled for laparoscopic cholecystectomy under general anesthesia...

INTRODUCTION: Non-communicable diseases (NCDs) disproportionately affect low- and lower-middle income countries (LLMICs) where 80% of global NCD related deaths occur. LLMICs are the primary focus of interventions to address development and poverty indicators. We aimed to synthesise the evidence of these interventions' impact on the four primary NCDs (cardiovascular disease, diabetes, chronic respiratory disease and cancer) and their common behavioural risk factors (unhealthy diets, physical inactivity, tobacco and alcohol use)...

Surfactant protein D (SP-D) is a multimeric collectin that is involved in innate immune defense and expressed in pulmonary, as well as non-pulmonary, epithelia. SP-D exerts antimicrobial effects and dampens inflammation through direct microbial interactions and modulation of host cell responses via a series of cellular receptors. However, low protein concentrations, genetic variation, biochemical modification, and proteolytic breakdown can induce decomposition of multimeric SP-D into low-molecular weight forms, which may induce pro-inflammatory SP-D signaling...

BACKGROUND: Obstructive sleep apnoea (OSA) and obesity are interdependent chronic diseases sharing reduced exercise tolerance and high cardiovascular risk. INTERVENTION: A 3-month intervention with innovative training modalities would further improve functional capacity and cardiovascular health than usual cycle exercise training in already continuous positive airway pressure (CPAP)-treated obese patients with OSA. METHODS: Fifty three patients (35<body mass index (BMI) <45 kg/m2 ) were randomly allocated to exercise training on a cycle ergometer, either alone (ERGO) or with respiratory muscle training (ERGO+RMT) or non-invasive ventilation (ERGO+NIV)...

The role for direct assessment of small airway function in subjects with respiratory symptoms but normal airflow by spirometry is discussed. Small airway disease syndrome is described in numerous disease states using a multidisciplinary approach. Data demonstrate that small airway disease is related to presence of respiratory symptoms, exposure to inhaled toxins, presence of local and systemic inflammation, and presence of histologic abnormalities within the distal lung. Investigation of immunological derangements associated with distal airway dysfunction in the setting of normal spirometry may provide insight into pathophysiological mechanisms that are present at disease onset...

BACKGROUND: Higher all-cause mortality in asthmatics has been shown previously. Polysensitization is associated with higher morbidity among asthmatic children, and allergic rhinitis and/or allergic conjunctivitis (AR/AC) are associated with higher morbidity in adult asthmatics. Little is known about the effect of AR/AC and other factors on mortality among adult asthmatics. The aim was to study mortality and its risk factors in adults with and without asthma. METHODS: We randomly selected 1648 asthmatics with age over 30 years from national registers and matched the asthma sample with one or two controls...

Multiple pathways contribute to nonalcoholic fatty liver disease (NAFLD) in response to high fat diets (HFD). A homolog of mammalian JNK-interacting protein 3 (JIP3), also known as JSAP-1, activates different components in various signaling pathways to modulate cellular processes. The purpose of this study was to examine the role of JIP3 in obesity-related pathologies pathway. Wild-type (WT) C57BL/6 and JIP3-knockout (JIP3-/- ) mice were randomized to chow or HFD. HFD-fed WT mice increased hepatic JIP3 expression...
