    Extracorporeal membrane oxygenation (ECMO) is a form of cardiopulmonary bypass that is a mainstay of therapy in neonatal and pediatric patients with life threatening respiratory and/or cardiac failure. Historically, the use of ECMO in adults has been limited, but recent reports and technological advances have increased utilization and interest in this technology in adult patients with severe respiratory failure. As ECMO is considered in this critically ill population, patient selection, indications, contraindications, comorbidities, and pre-ECMO support are all important considerations. Once the decision is made to cannulate a patient for ECMO, meticulous multi-organ-system management is required, with a priority being placed on lung rest and minimization of ventilator-induced lung injury. Close monitoring is also necessary for complications, some of which are related to ECMO and others secondary to the patient's underlying degree of illness. Despite the risks, reports demonstrate survival > 70% in some circumstances for patients requiring ECMO for refractory respiratory failure. As the utilization of ECMO in adult patients with respiratory failure continues to expand, ongoing discussion and investigation are needed to determine whether ECMO should remain a "rescue" therapy or if earlier ECMO may be beneficial as a lung-protective strategy.

    Nemaline myopathy is a rare congenital myopathy that generally presents in childhood. We report a case of a 44-year-old man who presented with severe hypoxic hypercapnic respiratory failure as the initial manifestation of nemaline myopathy. After starting noninvasive ventilation, his pulmonary function test results improved substantially, and over the 4 years since diagnosis his respiratory function remained stable. There are few reported cases of respiratory failure in patients with adult-onset nemaline myopathy, and the insidious onset in this case is even more unusual. This case highlights the varied presenting features of adult-onset nemaline myopathy and that noninvasive ventilation improves respiratory function.

    Full Text Available Abstract Background An estimated 350 adults develop severe, but potentially reversible respiratory failure in the UK annually. Current management uses intermittent positive pressure ventilation, but barotrauma, volutrauma and oxygen toxicity can prevent lung recovery. An alternative treatment, extracorporeal membrane oxygenation, uses cardio-pulmonary bypass technology to temporarily provide gas exchange, allowing ventilator settings to be reduced. While extracorporeal membrane oxygenation is proven to result in improved outcome when compared to conventional ventilation in neonates with severe respiratory failure, there is currently no good evidence from randomised controlled trials to compare these managements for important clinical outcomes in adults, although evidence from case series is promising. Methods/Design The aim of the randomised controlled trial of Conventional ventilatory support vs extracorporeal membrane oxygenation for severe adult respiratory failure (CESAR is to assess whether, for patients with severe, but potentially reversible, respiratory failure, extracorporeal membrane oxygenation will increase the rate of survival without severe disability ('confined to bed' and 'unable to wash or dress' by six months post-randomisation, and be cost effective from the viewpoints of the NHS and society, compared to conventional ventilatory support. Following assent from a relative, adults (18–65 years with severe, but potentially reversible, respiratory failure (Murray score ≥ 3.0 or hypercapnea with pH Discussion Analysis will be based on intention to treat. A concurrent economic evaluation will also be performed to compare the costs and outcomes of both treatments.

    Anesthesiologists have the privilege and challenge of providing care for an extremely diverse population of patients, at times in urgent or emergent situations. We present a case of a 31-year-old woman with Pierre Robin sequence, severe juvenile scoliosis, and respiratory failure who underwent successful awake nasal fiberoptic intubation for tracheostomy at an adult tertiary care medical center. Familiarity with patient conditions infrequently encountered within our practice, as well as adherence to practice guidelines, proved essential to providing our patient with the safest care possible.

    Extracorporeal membrane oxygenation (ECMO) provides complete or partial support of the heart and lungs. Ever since its inception in the 1960s, it has been used across all age groups in the management of refractory respiratory failure and cardiogenic shock. While it has gained widespread acceptance in the neonatal and pediatric physician community, ECMO remains a controversial therapy for Acute Respiratory Distress Syndrome (ARDS) in adults. Its popularity was revived during the swine flu (H1N1) pandemic and advancements in technology have contributed to its increasing usage. ARDS continues to be a potentially devastating condition with significant mortality rates. Despite gaining more insights into this entity over the years, mechanical ventilation remains the only life-saving, yet potentially harmful intervention available for ARDS. ECMO shows promise in this regard by offering less dependence on mechanical ventilation, thereby potentially reducing ventilator-induced injury. However, the lack of rigorous clinical data has prevented ECMO from becoming the standard of care in the management of ARDS. Therefore, the results of two large ongoing randomized trials, which will hopefully throw more light on the role of ECMO in the management of this disease entity, are keenly awaited. In this article we will provide a basic overview of the development of ECMO, the types of ECMO, the pathogenesis of ARDS, different ventilation strategies for ARDS, the role of ECMO in ARDS and the role of ECMO as a bridge to lung transplantation.

    Full Text Available Background: Administering extracorporeal membrane oxygenation (ECMO to critically ill patients with acute respiratory distress syndrome has substantially increased over the last decade, however administering ECMO to patients with hematologic malignancies may carry a particularly high risk. Here, we report the clinical outcomes of patients with hematologic malignancies and severe acute respiratory failure who were treated with ECMO. Methods: We performed a retrospective review of the medical records of patients with hematologic malignancies and severe acute respiratory failure who were treated with ECMO at the medical intensive care unit of a tertiary referral hospital between March 2010 and April 2015. Results: A total of 15 patients (9 men; median age 45 years with hematologic malignancies and severe acute respiratory failure received ECMO therapy during the study period. The median values of the Acute Physiology and Chronic Health Evaluation II score, Murray Lung Injury Score, and Respiratory Extracorporeal Membrane Oxygenation Survival Prediction Score were 29, 3.3, and -2, respectively. Seven patients received venovenous ECMO, whereas 8 patients received venoarterial ECMO. The median ECMO duration was 2 days. Successful weaning of ECMO was achieved in 3 patients. Hemorrhage complications developed in 4 patients (1 pulmonary hemorrhage, 1 intracranial hemorrhage, and 2 cases of gastrointestinal bleeding. The longest period of patient survival was 59 days after ECMO initiation. No significant differences in survival were noted between venovenous and venoarterial ECMO groups (10.0 vs. 10.5 days; p = 0.56. Conclusions: Patients with hematologic malignancies and severe acute respiratory failure demonstrate poor outcomes after ECMO treatment. Careful and appropriate selection of candidates for ECMO in these patients is necessary.

    Full Text Available Extracorporeal membrane oxygenation (ECMO for severe acute respiratory failure was proposed more than 40 years ago. Despite the publication of the ARDSNet study and adoption of lung protective ventilation, the mortality for acute respiratory failure due to acute respiratory distress syndrome has continued to remain high. This technology has evolved over the past couple of decades and has been noted to be safe and successful, especially during the worldwide H1N1 influenza pandemic with good survival rates. The primary indications for ECMO in acute respiratory failure include severe refractory hypoxemic and hypercarbic respiratory failure in spite of maximum lung protective ventilatory support. Various triage criteria have been described and published. Contraindications exist when application of ECMO may be futile or technically impossible. Knowledge and appreciation of the circuit, cannulae, and the physiology of gas exchange with ECMO are necessary to ensure lung rest, efficiency of oxygenation, and ventilation as well as troubleshooting problems. Anticoagulation is a major concern with ECMO, and the evidence is evolving with respect to diagnostic testing and use of anticoagulants. Clinical management of the patient includes comprehensive critical care addressing sedation and neurologic issues, ensuring lung recruitment, diuresis, early enteral nutrition, treatment and surveillance of infections, and multisystem organ support. Newer technology that delinks oxygenation and ventilation by extracorporeal carbon dioxide removal may lead to ultra-lung protective ventilation, avoidance of endotracheal intubation in some situations, and ambulatory therapies as a bridge to lung transplantation. Risks, complications, and long-term outcomes and resources need to be considered and weighed in before widespread application. Ethical challenges are a reality and a multidisciplinary approach that should be adopted for every case in consideration.

    Background: Biotinidase deficiency (BD) is a rare, inherited autosomal recessive disorder that is treatable within childhood. We present a patient with pneumonia and respiratory acidosis who was not diagnosed with any systemic disorders; the patient was finally diagnosed as BD. Case Report: A thirty-year-old woman was admitted to the emergency department with respiratory failure that had persisted for a few days and progressively weakening over the previous six months. Then, the patient was admitted to the intensive care unit with marked respiratory acidosis, respiratory failure and alterations in consciousness. At the follow-up, the patient was not diagnosed with a systematic disorder. Rather, the patient’s historical clinical findings suggested a metabolic disorder. Finally, the patient was diagnosed with biotinidase deficiency. Conclusion: Even though biotinidase deficiency is not frequently seen in the intensive care unit, metabolic syndromes such as biotinidase deficiency should be considered. Patients should be evaluated holistically with attention to medical history, family history and clinical findings. PMID:27761288

    Respiratory failure complicating the course of diabeticketoacidosis (DKA) is a source of increased morbidityand mortality. Detection of respiratory failure in DKA requiresfocused clinical monitoring, careful interpretationof arterial blood gases, and investigation for conditionsthat can affect adversely the respiration. Conditions thatcompromise respiratory function caused by DKA can bedetected at presentation but are usually more prevalentduring treatment. These conditions include deficits ofpotassium, magnesium and phosphate and hydrostatic ornon-hydrostatic pulmonary edema. Conditions not causedby DKA that can worsen respiratory function under theadded stress of DKA include infections of the respiratorysystem, pre-existing respiratory or neuromuscular diseaseand miscellaneous other conditions. Prompt recognitionand management of the conditions that can lead torespiratory failure in DKA may prevent respiratory failureand improve mortality from DKA.

Data including comorbidities, Sequential Organ Failure Assessment (SOFA score, Acute Physiological Assessment and Chronic Health Evaluation II (APACHE II score, PaO2, FiO2, PaO2/FiO2, PEEP, mean airway pressure (mPaw, and oxygenation index (OI on the 1st and the 3rd day of mechanical ventilation, and change in OI within 3 days were recorded. Primary outcome was hospital mortality; secondary outcome measure was ventilator weaning failure. Results. 38 out of 100 (38% patients died within the study period. 48 patients (48% failed to wean from ventilator. Multivariate analysis showed day 3 OI ( and SOFA ( score were independent predictors of hospital mortality. Preexisting cerebrovascular accident (CVA ( was the predictor of weaning failure. Results from Kaplan-Meier method demonstrated that higher day 3 OI was associated with shorter survival time (log-Rank test, . Conclusion. Early OI (within 3 days and SOFA score were predictors of mortality in severe acute respiratory failure. In the future, prospective studies measuring serial OIs in a larger scale of study cohort is required to further consolidate our findings.

  13. Respiratory failure in elderly patients.

    Elderly individuals comprise an increasing proportion of the population and represent a progressively expanding number of patients admitted to the ICU. Because of underlying pulmonary disease, loss of muscle mass, and other comorbid conditions, older persons are at increased risk of developing respiratory failure. Recognition of this vulnerability and the adoption of proactive measures to prevent decompensation requiring intrusive support are major priorities together with clear delineation of patients' wishes regarding the extent of support desired should clinical deterioration occur. Further, the development of coordinated approaches to identify patients at risk for respiratory failure and strategies to prevent the need for intubation, such as the use of NIV in appropriate patients, are crucial. As soon as endotracheal intubation and mechanical ventilation are implemented strategies that facilitate the liberation of elderly patients from the ventilator are especially important. The emphasis on a team approach, which characterizes geriatric medicine, is essential in coordinating the skills of multiple health care professionals in this setting. Respiratory failure can neither be effectively diagnosed nor managed in isolation. Integration with all other aspects of care is essential. Patient vulnerability to nosocomial complications and the "cascade effect" of these problems such as the effects of medications and invasive supportive procedures all impact on respiratory care of elderly patients. For example, prolonged mechanical ventilation may be required long after resolution of the underlying cause of respiratory failure because of unrecognized and untreated delirium or residual effects of small doses of sedative and/or analgesic agents or other medications in elderly patients with altered drug metabolism. The deleterious impact of the foreign and sometimes threatening ICU environment and/or sleep deprivation on the patient's course are too often overlooked because

    Adult respiratory distress syndrome (ARDS) has now been described as a sequela to such diverse conditions as burns, amniotic fluid embolism, acute pancreatitis, trauma, sepsis and damage as a result of elective surgery in general. Patients with ARDS require immediate intubation, with the average patient now being ventilated for between 8 and 11 days. While the acute management of ARDS is conducted by the critical care team, almost any surgical patient can be affected by the condition and we believe that it is important that a broader spectrum of hospital doctors gain an understanding of the nature of the pathology and its current treatment.

    2012-07-01

    Use of high flow nasal cannula oxygen (HFNC) is increasingly popular in adult ICUs for patients with acute hypoxemic respiratory failure. This is the result of the successful long-term use of HFNC in the neonatal field and recent clinical data in adults indicating beneficial effects of HFNC over conventional facemask oxygen therapy. HFNC rapidly alleviates symptoms of respiratory distress and improves oxygenation by several mechanisms, including deadspace washout, reduction in oxygen dilution and in inspiratory nasopharyngeal resistance, a moderate positive airway pressure effect that may generate alveolar recruitment and an overall greater tolerance and comfort with the interface and the heated and humidified inspired gases. Indications of HFNC are broad, encompassing most if not all causes of acute hypoxemic respiratory failure. HFNC can also provide oxygen during invasive procedures, and be used to prevent or treat post-extubation respiratory failure. HFNC may also alleviate respiratory distress in patients at a palliative stage. Although observational studies suggest that HFNC might reduce the need for intubation in acute hypoxemic respiratory failure; such a reduction has not yet been demonstrated. Beyond this potential additional effect on outcome, the evidence already published argues in favor of the large use of HFNC as first line therapy for acute respiratory failure.

Materials and methods. Double-lumen cannula 22 F was placed percutaneously in the right internal jugular vein. The ext- racorporeal contour reduced in length and the polymethylpeptene oxygenator (priming volume 175 ml were also. Results. In 1 hour after the beginning of VV ECMO, we registered the noted improvement of arterial blood gas and acid-base balance (regress of respiratory acidosis, improvement of arterial oxygenation which allowed us to use the «protective» mode of mechanical ventilation. Improvement of gas exchange and regress of clinical and radiological manifestations of ARDS allowed for VV ECMO weaning and decannulation on day 7. The patient was discharged from ICU and then from our Centre to a homestay respectively on the 9th and 16th day after VV ECMO weaning with the satisfactory liver graft and lungs function. Conclusion. VV ECMO can be successfully applied to correct the life-threatening acute respiratory failure in the early period after liver transplantation.

    Although, miliary tuberculosis is an unusual cause of severe acute respiratory failure, we describe nine patients with miliary tuberculosis who developed adult respiratory distress syndrome. This complication occurred in seven patients despite treatment with antituberculous drugs. In two patients who developed the syndrome, miliary tuberculosis was diagnosed only at postmortem. The presence of pulmonary hypertension in all cases and disseminated intravascular coagulation in seven cases suggests a possible pathophysiologic relationship with severe pulmonary vascular damage. The high mortality rate (88.8%) was associated with nonpulmonary organ system failure. Miliary tuberculosis should be considered in patients with adult respiratory distress syndrome of unknown etiology, and simple diagnostic procedures such as sputum, bronchial brushing, and gastric examination should be followed by invasive diagnostic procedures to confirm this etiology. Since untreated miliary tuberculosis is usually fatal, early recognition of this disease is of great importance, and specific therapy may play a lifesaving role.

Beyond pharmacological treatment, supplemental oxygen and mechanical ventilation are major treatment options. This review describes the physiological concepts underlying respiratory failure and its therapy, as well as important treatment outcomes. The rationale for the controlled supply of oxygen in acute hypoxic respiratory failure is undisputed. There is also a clear survival benefit from long-term oxygen therapy in patients with chronic hypoxia, while in mild, nocturnal, or exercise-induced hypoxemia such long-term benefits appear questionable. Furthermore, much evidence supports the use of non-invasive positive pressure ventilation in acute hypercapnic respiratory failure. It application reduces intubation and mortality rates, and the duration of intensive care unit or hospital stays, particularly in the presence of mild to moderate respiratory acidosis. COPD with chronic hypercapnic respiratory failure became a major indication for domiciliary mechanical ventilation, based on pathophysiological reasoning and on data regarding symptoms and quality of life. Still, however, its relevance for long-term survival has to be substantiated in prospective controlled studies. Such studies might preferentially recruit patients with repeated hypercapnic decompensation or a high risk for death, while ensuring effective ventilation and the patients’ adherence to therapy.Keywords: respiratory failure, COPD, mechanical ventilation, non-invasive ventilation long-term oxygen therapy, chronic

    Extracorporeal membrane oxygenation (ECMO) for neonatal and pediatric cardiac and/or respiratory failure is well established, and its use for adult respiratory failure is rapidly increasing. Management strategies developed over the past 30 years coupled with significant recent technological advances have led to improved ECMO survival. These new technologies are expanding the potential applications for ECMO in exciting ways, including new patient populations and the ability to make ECMO mobile for both intra- and inter-hospital transport. In this article, we highlight some of the recent technological advances and their impact on the utilization of ECMO in increasingly diverse patient populations.

    Introduction: Antisynthetase syndrome (ASS) is characterized by the presence of anti-Jo-1 antibodies in conjunction with clinical findings of fever, polymyositis-dermatomyositis, and interstitial lung disease (ILD). Inflammatory myopathies carry a high risk of malignancy, but this association is less well outlined in ASS. We present the case of a patient with ASS who developed non-Hodgkin's lymphoma with acute hypoxemic respiratory failure. Case Presentation: A 44-year-old female with ASS presented with acute hypoxemic respiratory failure. She was empirically treated with broad-spectrum antibiotics for a health care-associated pneumonia; however, she failed to improve. Chest computed tomography revealed extensive bilateral ground glass opacities as well as extensive mediastinal and axillary lymphadenopathy. Infectious workup was negative. A surgical lung biopsy revealed peripheral T-cell lymphoma (PTCL). The patient was started on chemotherapy with complete resolution of hypoxemic respiratory failure. Conclusions: Malignancy is very rare in the setting of ASS; and our case illustrates the unique presentation of PTCL in ASS. In addition, lung involvement in PTCL is variable (incidence ranging from 8% to 20%); and in this case, bilateral multifocal consolidation was biopsied and proven to be PTCL involving the lungs. This case highlights the rare noninfectious conditions that can present as acute hypoxemic respiratory failure in the setting of ASS.

    Full Text Available Noninvasive ventilation (NIV refers to positive pressure ventilation delivered through a noninvasive interface (nasal mask, facemask, or nasal plugs etc. Over the past decade its use has become more common as its benefits are increasingly recognized. This review will focus on the evidence supporting the use of NIV in various conditions resulting in acute hypoxemic respiratory failure (AHRF, that is, non-hypercapnic patients having acute respiratory failure in the absence of a cardiac origin or underlying chronic pulmonary disease. Outcomes depend on the patient's diagnosis and clinical characteristics. Patients should be monitored closely for signs of noninvasive ventilation failure and promptly intubated before a crisis develops. The application of noninvasive ventilation by a trained and experienced team, with careful patient selection, should optimize patient outcomes.

    Full Text Available Ovarian hyperstimulation syndrome is a serious and potentially life-threatening physiological complication that may be encountered in patients who undergo controlled ovarian hyperstimulation cycles. The syndrome is typically associated with regimes of exogenous gonadotropins, but it can be seen, albeit rarely, when clomiphene is administered during the induction phase. Although this syndrome is widely described in scientific literature and is well known by obstetricians, the knowledge of this pathological and potentially life-threatening condition is generally less than satisfactory among physicians. The dramatic increase in therapeutic strategies to treat infertility has pushed this condition into the realm of acute care therapy. The potential complications of this syndrome, including pulmonary involvement, should be considered and identified so as to allow a more appropriate diagnosis and management. We describe a case of a woman with an extremely severe (Stage 6 ovarian hyperstimulation syndrome who presented ascites, bilateral pleural effusion and severe respiratory failure treated with non-invasive ventilation. The patient was admitted to the intensive care unit because of severe respiratory failure, ascites, and bilateral pleural effusion due to ovarian hyperstimulation syndrome. Treatment included non-invasive ventilation and three thoracentesis procedures, plus the administration of albumin, colloid solutions and high-dose furosemid. Severe form of ovarian hyperstimulation syndrome is observed in 0.5-5% of the women treated, and intensive care may be required for management of thromboembolic complications, renal failure and severe respiratory failure. Pulmonary intensive care may involve thoracentesis, oxygen supplementation and, in more severe cases, assisted ventilation. To our knowledge, there have been only two studies in English language medical literature that describe severe respiratory failure treated with non

Both techniques, and some others that have been recently introduced and which integrate some technological innovations, have extensively demonstrated a faster improvement of acute respiratory failure in different patient populations, avoiding endotracheal intubation and facilitating the release of conventional invasive mechanical ventilation. In acute settings, NIV is currently the first-line treatment for moderate-to-severe chronic obstructive pulmonary disease exacerbation as well as for acute cardiogenic pulmonary edema and should be considered in immunocompromised patients with acute respiratory insufficiency, in difficult weaning, and in the prevention of postextubation failure. Alternatively, it can also be used in the postoperative period and in cases of pneumonia and asthma or as a palliative treatment. NIV is currently used in a wide range of acute settings, such as critical care and emergency departments, hospital wards, palliative or pediatric units, and in pre-hospital care. It is also used as a home care therapy in patients with chronic pulmonary or sleep disorders. The appropriate selection of patients and the adaptation to the technique are the keys to success. This review essentially analyzes the evidence of benefits of NIV in different populations with acute respiratory failure and describes the main modalities, new devices, and some practical aspects of the use of this technique.

    Acute respiratory failure (ARF) is a leading indication for performing critical care ultrasonography (CCUS) which, in these patients, combines critical care echocardiography (CCE) and chest ultrasonography. CCE is ideally suited to guide the diagnostic work-up in patients presenting with ARF since it allows the assessment of left ventricular filling pressure and pulmonary artery pressure, and the identification of a potential underlying cardiopathy. In addition, CCE precisely depicts the consequences of pulmonary vascular lesions on right ventricular function and helps in adjusting the ventilator settings in patients sustaining moderate-to-severe acute respiratory distress syndrome. Similarly, CCE helps in identifying patients at high risk of ventilator weaning failure, depicts the mechanisms of weaning pulmonary edema in those patients who fail a spontaneous breathing trial, and guides tailored therapeutic strategy. In all these clinical settings, CCE provides unparalleled information on both the efficacy and tolerance of therapeutic changes. Chest ultrasonography provides further insights into pleural and lung abnormalities associated with ARF, irrespective of its origin. It also allows the assessment of the effects of treatment on lung aeration or pleural effusions. The major limitation of lung ultrasonography is that it is currently based on a qualitative approach in the absence of standardized quantification parameters. CCE combined with chest ultrasonography rapidly provides highly relevant information in patients sustaining ARF. A pragmatic strategy based on the serial use of CCUS for the management of patients presenting with ARF of various origins is detailed in the present manuscript.

    A 24-year-old woman with quadriplegia was admitted with respiratory failure because of pneumonia. She was on multiple medications including diazepam, oxycodone, and amitriptyline, known to be associated with coma blisters, though she did not overdose on any of them. On hospital day 2, she developed multiple blisters on both sides of her right forearm and hand. Skin biopsy showed eccrine gland degeneration consistent with coma blisters. It was felt that hypoxemia from her pneumonia contributed to the development of these blisters, which occurred on both pressure and non-pressure bearing areas of the arm. Coma blisters are self-limited skin lesions that occur at sites of maximal pressure, mostly in the setting of drug overdose. However, coma blisters may occur with metabolic and neurological conditions resulting in coma.

    Intestinal failure (IF) is the inability of the alimentary tract to digest and absorb sufficient nutrition to maintain normal fluid balance, growth, and health. It commonly arises from disease affecting the mesenteric root. Although severe IF is usually managed in specialized units, it lies at the end of a spectrum with degrees of nutritional compromise being widely encountered, but commonly under-recognized. Furthermore, in the majority of cases, the initial enteric insult occurs in non-specialist IF centres. The aim of this article is to review the common causes of IF, general principles of its management, some commoner complications, and the role of radiology in the approach to a patient with severe IF. The radiologist has a crucial role in helping provide access for feeding solutions (both enteral and parenteral) and controlling sepsis (via drainage of collections) in an initial restorative phase of treatment, whilst simultaneously mapping bowel anatomy and quality, and searching for disease complications to assist the clinicians in planning a later, restorative phase of therapy.

    2013-03-01

    Full Text Available Introduction: The application of continuous positive airway pressure (CPAP is one of the most important therapeutic interventions used in patients with acute respiratory failure (ARF secondary to acute cardiogenic pulmonary edema (ACPE. Thanks to its positive effects on both hemodynamics and ventilation, CPAP improves clinical and blood-gas parameters. Compared with standard oxygen therapy, use of CPAP is associated with decreased mortality and reduced need for intubation in these patients. Aim of the study: This review examines the principles of CPAP, techniques and equipment used to deliver it, and clinical applications. Special emphasis is placed on CPAP delivered with the Boussignac device. Discussion and conclusions: In emergency departments, this simple, lightweight, disposable device has proved to be well tolerated and similar to Venturi-like flow generators in terms of effectiveness. These findings suggest that Boussignac CPAP might be useful for managing ARF in non-critical care areas where other more complicated CPAP equipment (Venturi-like flow generators and ventilators are not available (for example, in general medical wards.

    Conventional treatment of respiratory failure involves positive pressure ventilation that can worsen lung damage. Extracorporeal membrane oxygenation (ECMO) is typically used when conventional therapy fails. In this study, we evaluated the use of venovenous (VV)-ECMO for the treatment of severe pediatric respiratory failure at our institution. A retrospective analysis of pediatric patients (age 1-18) placed on ECMO in the last 15 years (1999-2014) by the pediatric surgery team for respiratory failure was performed. Five pediatric patients underwent ECMO (mean age 10 years; range, 2-16). All underwent VV-ECMO. Diagnoses were status asthmaticus (2), acute respiratory distress syndrome due to septic shock (1), aspergillus pneumonia (1), and respiratory failure due to parainfluenza (1). Two patients had severe barotrauma prior to ECMO initiation. Average oxygenation index (OI) prior to cannulation was 74 (range 23-122). No patients required conversion to VA-ECMO. The average ECMO run time was 4.4 days (range 2-6). The average number of days on the ventilator was 15 (range 4-27). There were no major complications due to the procedure. Survival to discharge was 100%. Average follow up is 4.4 years (range 1-15). A short run of VV-ECMO can be lifesaving for pediatric patients in respiratory failure. Survival is excellent despite severely elevated oxygen indices. VV-ECMO may be well tolerated and can be considered for severe pediatric respiratory failure.

    Pulmonary agenesis (PA) is a rare congenital anomaly, which may be unilateral or bilateral. Unilateral PA may be associated with nonspecific respiratory symptoms. We report the case of 5-month-old infant who presented a normal development until the age of 4 months when a respiratory infection caused an acute respiratory distress syndrome with a fatal outcome. The autopsy findings depicted the right lung agenesis without any other concomitant malformation. Although respiratory symptoms represent frequent complaints in pediatrics, the aim of this study is not only to draw attention to the unilateral pulmonary agenesis as a possible underlying malformation in children who present recurrent and severe respiratory symptoms, but also to report a case diagnosed at autopsy.

The objective of this study was to assess the relation of the occurrence of respiratory infections in the past 12 months to adult-onset asthma in a population-based incident case-control study of adults 21-63 years of age. METHODS/PRINCIPAL FINDINGS: We recruited all new clinically diagnosed cases of asthma (n = 521 during a 2.5-year study period and randomly selected controls (n = 932 in a geographically defined area in South Finland. Information on respiratory infections was collected by a self-administered questionnaire. The diagnosis of asthma was based on symptoms and reversible airflow obstruction in lung function measurements. The risk of asthma onset was strongly increased in subjects who had experienced in the preceding 12 months lower respiratory tract infections (including acute bronchitis and pneumonia with an adjusted odds ratio (OR 7.18 (95% confidence interval [CI] 5.16-9.99, or upper respiratory tract infections (including common cold, sinusitis, tonsillitis, and otitis media with an adjusted OR 2.26 (95% CI 1.72-2.97. Individuals with personal atopy and/or parental atopy were more susceptible to the effects of respiratory infections on asthma onset than non-atopic persons. CONCLUSIONS/SIGNIFICANCE: This study provides new evidence that recently experienced respiratory infections are a strong determinant for adult-onset asthma. Reducing such infections might prevent onset of asthma in adulthood, especially in individuals with atopy or hereditary propensity to it.

    2013-11-01

    Organophosphate (OP) pesticide poisoning is a global health problem with over 250,000 deaths per year. OPs affect neuronal signaling through acetylcholine (Ach) neurotransmission via inhibition of acetylcholinesterase (AChE), leading to accumulation of Ach at the synaptic cleft and excessive stimulation at post-synaptic receptors. Mortality due to OP agents is attributed to respiratory dysfunction, including central apnea. Cholinergic circuits are integral to many aspects of the central control of respiration, however it is unclear which mechanisms predominate during acute OP intoxication. A more complete understanding of the cholinergic aspects of both respiratory control as well as neural modification of pulmonary function is needed to better understand OP-induced respiratory dysfunction. In this article, we review the physiologic mechanisms of acute OP exposure in the context of the known cholinergic contributions to the central control of respiration. We also discuss the potential central cholinergic contributions to the known peripheral physiologic effects of OP intoxication.

    Background Severe acute respiratory syndrome is frequently complicated by respiratory failure requiring ventilatory support. We aimed to compare the efficacy of non-invasive ventilation against invasive mechanical ventilation treating respiratory failure in this disease. Methods Retrospective analysis was conducted on all respiratory failure patients identified from the Hong Kong Hospital Authority Severe Acute Respiratory Syndrome Database. Intubation rate, mortality and secondary outcome of a hospital utilizing non-invasive ventilation under standard infection control conditions (NIV Hospital) were compared against 13 hospitals using solely invasive ventilation (IMV Hospitals). Multiple logistic regression analyses with adjustments for confounding variables were performed to test for association between outcomes and hospital groups. Results Both hospital groups had comparable demographics and clinical profiles, but NIV Hospital (42 patients) had higher lactate dehydrogenase ratio and worse radiographic score on admission and ribavirin-corticosteroid commencement. Compared to IMV Hospitals (451 patients), NIV Hospital had lower adjusted odds ratios for intubation (0.36, 95% CI 0.164-0.791, P=0.011) and death (0.235, 95% CI 0.077-0.716, P=0.011), and improved earlier after pulsed steroid rescue. There were no instances of transmission of severe acute respiratory syndrome among health care workers due to the use of non-invasive ventilation.Conclusion Compared to invasive mechanical ventilation, non-invasive ventilation as initial ventilatory support for acute respiratory failure in the presence of severe acute respiratory syndrome appeared to be associated with reduced intubation need and mortality.

    Full Text Available A 40 year old woman presented with a short history of acute onset of breathlessness to the ER of our hospital and after initial evaluation for acute pulmonary embolism which was ruled out after carrying out the appropriate investigations, she was diagnosed to be afflicted with syringomyelia based on her neurological symptoms and clinical findings, which was confirmed by doing an MRI scan, which was her basic diagnosis that was complicated by acute hypercapnic respiratory failure. This case is being reported to highlight syringomyelia as an unusual cause of acute respiratory failure, which manifested clinically in this patient as its first presentation and the underlying neurological diagnosis has been found to be present in very few reported cases (less than 0.01% of case reports in the available literature as the basic disease in the absence of its classical presenting features. Problems associated with acute respiratory failure in the setting of syringomyelia are discussed.

    Hypercarbic respiratory failure, occurring secondary to chronic lung disease, is a frequently encountered problem. These patients present a significant challenge to respiratory and critical care services, as many are unsuitable for mechanical ventilation and most have multiple comorbidities. Recently, noninvasive ventilation (NIV) has become established as the primary modality for respiratory support in this group of patients. Several factors limit patient compliance with NIV, not least comfort and tolerability. A recent innovation in adult critical care is the use of high-flow nasal oxygen (HFNO) devices. These systems are capable of delivering high gas flows via nasal cannulae, with the ability to blend air and oxygen to give a controlled FiO2. Few clinical studies have been conducted in adults, although several are planned. To date the majority of available evidence addresses the use of HFNO in hypoxemic respiratory failure. Here we present a case in which a HFNO system was used to successfully manage hypercarbic respiratory failure in a patient unable to tolerate conventional NIV.

Seventy-eight patients (57 males, mean age 78.3 ± 9.2 years undergoing NIV were evaluated. Of them, 48 (62.3% had acute hypercapnic respiratory failure because of a chronic obstructive pulmonary disease exacerbation, and the remaining 30 had acute hypercapnic respiratory failure from other causes, mainly cardiac failure. All patients were treated by NIV using the bi-level positive airway pressure set up at high pressure/high backup rate. NIV was successful in 67 subjects (85.9% and the patients were discharged, 57 of whom continued NIV at home and ten had spontaneous breathing. NIV was unsuccessful in eleven patients, ten of whom died and one was successfully treated by invasive mechanical ventilation. Significant differences were detected for a higher basal Glasgow Coma Scale score in successfully treated patients (P = 0.007, a higher basal Acute Physiology and Chronic Health Evaluation score in unsuccessfully treated patients (P = 0.004, and a lower pH after 1 hour in unsuccessfully treated patients (P = 0.015. These findings show a very high rate of success of NIV in patients with acute hypercapnic respiratory failure not only from chronic obstructive pulmonary disease but also from cardiac failure. This suggests that the use of invasive mechanical ventilation may be further reduced, with a decrease in its known complications as well.

    Acute respiratory failure represents one of the most common causes of intensive care unit admission and oxygen therapy remains the first-line therapy in the management of these patients. In recent years, high-flow oxygen via nasal cannula has been described as a useful alternative to conventional oxygen therapy in patients with acute respiratory failure. High-flow oxygen via nasal cannula rapidly alleviates symptoms of acute respiratory failure and improves oxygenation by several mechanisms, including dead space washout, reduction in oxygen dilution and inspiratory nasopharyngeal resistance, a moderate positive airway pressure effect that may generate alveolar recruitment and an overall greater tolerance and comfort with the interface and the heated and humidified inspired gases. However, the experience in adults is still limited and there are no clinical guidelines to establish recommendations for their use. This article aims to review the existing evidence on the use of high-flow oxygen via nasal cannula in adults with acute respiratory failure and its possible applications, advantages and limitations.

    Heart failure (HF) is a leading cause of morbidity, hospitalization, and mortality in older adults and a growing public health problem placing a huge financial burden on the health care system. Many challenges exist in the assessment and management of HF in geriatric patients, who often have coexisting multimorbidity, polypharmacy, cognitive impairment, and frailty. These complex "geriatric domains" greatly affect physical and functional status as well as long-term clinical outcomes. Geriatric patients have been under-represented in major HF clinical trials. Nonetheless, available data suggest that guideline-based medical and device therapies improve morbidity and mortality. Nonpharmacologic strategies, such as exercise training and dietary interventions, are an active area of research. Targeted geriatric evaluation, including functional and cognitive assessment, can improve risk stratification and guide management in older patients with HF. Clinical trials that enroll older patients with multiple morbidities and HF and evaluate functional status and quality of life in addition to mortality and cardiovascular morbidity should be encouraged to guide management of this age group.

    2013-08-20

    Interstitial pneumonitis as an adverse effect of mesalamine therapy is a rare but potentially serious complication. Patients typically have a mild disease course with no documented cases of respiratory failure in published literature. Given its variable latent period and non-specific signs and symptoms, it may be difficult to diagnose. We present the case of a 65-year-old man who presented with symptoms of fever, shortness of breath and a non-productive cough, 2 weeks after initiation of therapy with mesalamine. His hospital course was complicated by acute respiratory failure requiring intubation and mechanical ventilation. Radiographic studies revealed bilateral lower lobe infiltrates and bronchosopy with bronchoalveolar lavage and transbronchial biopsy were consistent with a diagnosis of drug-induced interstitial pneumonitis. The aim of this paper is to highlight the importance of considering a diagnosis of mesalamine-induced lung injury in patients presenting with respiratory symptoms while on mesalamine therapy and to review relevant literature.

    2015-08-01

    Respiratory sleep disorders (RSD) occur in about 40-50% of patients with symptomatic congestive heart failure (CHF). Obstructive sleep apnea (OSA) is considered a cause of CHF, whereas central sleep apnea (CSA) is considered a response to heart failure, perhaps even compensatory. In the setting of heart failure, continuous positive airway pressure (CPAP) has a definite role in treating OSA with improvements in cardiac parameters expected. However in CSA, CPAP is an adjunctive therapy to other standard therapies directed towards the heart failure (pharmacological, device and surgical options). Whether adaptive servo controlled ventilatory support, a variant of CPAP, is beneficial is yet to be proven. Supplemental oxygen therapy should be used with caution in heart failure, in particular, by avoiding hyperoxia as indicated by SpO2 values >95%.

All had respiratory acidosis (mean pH 7.17), hypercapni a (mean PaCO2 94.10mmHg) (63.97~143.18mmHg), and hypoxemia (mean PaO2 39mmHg) (29.03~44.03mmHg). During periods of clinical stability all but 2 had awaken hypercapnia (mean PaCO2 46.73mmHg) (38.25~54.68mmHg). Four of the 9 patients had pulmonary function test showing FEV1>70%. Conclusion OSAS induced acute respiratory fail ure has a sudden onset and various presentations and can be reversed with early and proper treatment. The severity of abnormal pulmonary function was less than what would be expected to cause respiratory failure.

    Full Text Available OBJECTIVE: Post-operative pulmonary complications significantly affect patient survival rates, but there is still no conclusive evidence regarding the effect of post-operative respiratory failure after liver transplantation on patient prognosis. This study aimed to predict the risk factors for post-operative respiratory failure (PRF after liver transplantation and the impact on short-term survival rates. DESIGN: The retrospective observational cohort study was conducted in a twelve-bed adult surgical intensive care unit in northern Taiwan. The medical records of 147 liver transplant patients were reviewed from September 2002 to July 2007. Sixty-two experienced post-operative respiratory failure while the remaining 85 patients did not. MEASUREMENTS AND MAIN RESULTS: Gender, age, etiology, disease history, pre-operative ventilator use, molecular adsorbent re-circulating system (MARS use, source of organ transplantation, model for end-stage liver disease score (MELD and Child-Turcotte-Pugh score calculated immediately before surgery were assessed for the two groups. The length of the intensive care unit stay, admission duration, and mortality within 30 days, 3 months, and 1 year were also evaluated. Using a logistic regression model, post-operative respiratory failure correlated with diabetes mellitus prior to liver transplantation, pre-operative impaired renal function, pre-operative ventilator use, pre-operative MARS use and deceased donor source of organ transplantation (p<0.05. Once liver transplant patients developed PRF, their length of ICU stay and admission duration were prolonged, significantly increasing their mortality and morbidity (p<0.001. CONCLUSIONS: The predictive pre-operative risk factors significantly influenced the occurrence of post-operative respiratory failure after liver transplantation.

    Many young working age adults in developed countries are failing to thrive in economic, demographic and social terms. Their 'failure to thrive' is a relatively new phenomenon that has not been widely recognized, but it affects young adults in virtually all the more developed countries for which we have relevant data. Young adults nowadays are more often in poverty. They are leaving their parental homes at ever later ages and in some countries the frequency of psychological problems increased....

    Full Text Available Objective: To enhance the clinician's awareness of Strongyloidiasis as a cause of critical illness. Design: A case report. Setting: A 600- bed, tertiary care hospital in New Delhi, India. Patient: A 53 years old diabetic male, presenting with acute respiratory failure, having received treatment for 2 weeks for acute bronchitis that included corticosteroids. He had a history of receiving several courses of treatment for Strongyloides stercoralis larvae detected in his stools. During this admission, he went on to develop neurological signs, cutaneous lesions and acute respiratory distress syndrome (ARDS. Negative stool examinations led to the diagnosis being delayed until the 7th day, when the larvae were demonstrated in the skin lesions and tracheal aspirate. Conclusion: Awareness of the varied presentations of Strongyloidiasis and a diligent search for the larvae at various sites are crucial for early diagnosis.

    Full Text Available Fourteen patients with severe neuroparalytic snake envenomation, resulting in acute type II respiratory failure, admitted to respiratory critical care unit for mechanical ventilation during one year period, were studied. Ventilatory requirements, amount of anti snake venom (ASV infused, period of neurological recovery and hospital survival were evaluated. All patients had severe manifestations such as ptosis, extraocular muscle paresis and limb weakness along with dyspnoea. Seven patients (50% had additional complaints of dysphagia and dysphonia. ASV was administered to all, with a median requirement of 900 ml. Mechanical ventilation was required for a median duration of 17 hours and all except one patient, who had suffered irreversible hypoxic cerebral injury prior to resuscitation, survived with complete neurological recovery. We conclude, that the timely institution of ventilatory support and anti-venom therapy in such patients, is associated with an excellent outcome.

Objective of this study is to verify applicability of NIV in a general non respiratory medical ward. We enrolled 68 consecutive patients (Pts with Hypoxemic or Hyper capnic ARF: acute cardiogenic pulmonary edema (ACPE, exacerbation of chronic obstructive pulmonary disease (COPD, Pneu - monia, acute lung injury / acute respiratory distress syndrome (ALI/ARDS. NIV treatment was CPAP or PSV + PEEP. 12 Pts (18,5% met primary endpoint (NIV failure: 11 Pts (17% needed ETI (5ALI/ARDS p < 0,0001, 6COPD 16,6%, 1 Patient (1,5% died (Pneumonia. No Pts with ACPE failed (p = 0,0027. Secondary endpoints: significant improvement in Respiratory Rate (RR, Kelly Score, pH, PaCO2, PaO2 vs baseline. Median duration of treatment: 16:06 hours: COPD 18:54, ACPE 4:15. Mean length of hospitalisation: 8.66 days. No patients discontinued NIV, no side effects. Results are consistent with literature. Hypoxemic ARF related to ALI/ARDS and pneumonia show worst outcome: it is not advisable to manage these conditions with NIV outside the ICU. NIV for ARF due to COPD and ACPE is feasible, safe and effective in a general medical ward if selection of Pts, staff’s training and monitoring are appropriate. This should encourage the diffusion of NIV in this specific setting. According to strong evidences in literature, NIV should be considered a first line and standard treatment in these clinical conditions irrespective of the setting.

    Full Text Available Hydrothorax secondary to a pancreaticopleural fistula (PPF is a rare complication of acute pancreatitis. In patients with a history of pancreatitis, diagnosis is made by detection of amylase in the pleural exudate. Imaging, particularly magnetic resonance cholangiopancreatography, aids in the detection of pancreatic ductal disruption. Management includes thoracocentesis and pancreatic duct drainage or pancreatic resection procedures. We present a case of massive right hydrothorax secondary to a PPF due to recurrent acute pancreatitis. Due to respiratory failure, urgent thoracocentesis was done. Distal pancreatectomy with splenectomy and cholecystectomy was performed. The patient remains well at one-year follow-up.

    Full Text Available PURPOSE: Acute respiratory failure (ARF is a common life-threatening complication in morbidly obese patients with obesity hypoventilation syndrome (OHS. We aimed to identify the determinants of noninvasive ventilation (NIV success or failure for this indication. METHODS: We prospectively included 76 consecutive patients with BMI>40 kg/m2 diagnosed with OHS and treated by NIV for ARF in a 15-bed ICU of a tertiary hospital. RESULTS: NIV failed to reverse ARF in only 13 patients. Factors associated with NIV failure included pneumonia (n = 12/13, 92% vs n = 9/63, 14%; p<0.0001, high SOFA (10 vs 5; p<0.0001 and SAPS2 score (63 vs 39; p<0.0001 at admission. These patients often experienced poor outcome despite early resort to endotracheal intubation (in-hospital mortality, 92.3% vs 17.5%; p<0.001. The only factor significantly associated with successful response to NIV was idiopathic decompensation of OHS (n = 30, 48% vs n = 0, 0%; p = 0.001. In the NIV success group (n = 63, 33 patients (53% experienced a delayed response to NIV (with persistent hypercapnic acidosis during the first 6 hours. CONCLUSIONS: Multiple organ failure and pneumonia were the main factors associated with NIV failure and death in morbidly obese patients in hypoxemic ARF. On the opposite, NIV was constantly successful and could be safely pushed further in case of severe hypercapnic acute respiratory decompensation of OHS.

    2013-07-22

    Benign goitres have the potential to reach massive sizes if neglected, but most have a protracted course that may or may not present with compressive symptoms. We report the case of a 57-year-old man who presented with a rapidly enlarging nodular goitre resulting in acute respiratory failure. Endotracheal intubation and emergency total thyroidectomy were performed, revealing massive thyroid nodules with minimal intrathoracic extension and tracheal erosion. Despite a course and clinical findings suggestive of malignant disease, histopathology was consistent with a benign multinodular goitre. Several cases of benign goitres necessitating endotracheal intubation have been reported. Airway compromise was attributed to a significant intrathoracic component, or inciting events such as thyroid haemorrhage, pregnancy, radioiodine uptake or major surgery. Obstructive symptoms may not correlate well with objective measures of upper airway obstruction such as radiographs or flow volume loops.

    Full Text Available Objective: The incidence of hypophosphatemia is higher in critically ill patients and prolonged the length of ICU stay and duration of mechanical ventilation. This study evaluated the prognostic value of phosphate levels in critically ill patients. Materials and Methods: All patients admitted to the general and surgical intensive care unit (ICU of Trakya University Medical Faculty, with respiratory failure during 1 year period (from January 1, 2009, to December 31, 2009, were retrospectively enrolled. The phosphate levels, age, gender, length of ICU stay, duration of mechanical ventilation, APACHE II scores, medical drug usage and prognosis were recorded. Hypophosphataemia was defined as a level under 2.5 mg/dL and normophosphatemia was defined as a level between 2.5-4.7 mg/dL. Results: 139 patients were retrospectively enrolled into the study, of these, 41% had hypophosphataemia. There was no statistically significant difference in age, gender and APACHE II scores. The length of ICU stay was 20.16±16.31 days in hypophosphatemic patients and 12.62±12.43 days in normophosphatemic patients (p<0.05. The duration of mechanical ventilation was 17.54±16.27 days in hypophosphatemic patients and 9.94±11.55 days in normophosphatemic patients (p<0.05. The usage of catecholamines, beta adrenergic receptor agonists, diuretics and glucocorticoids were higher in hypophosphatemic patients (p<0.05. Conclusion: The duration of mechanical ventilation and the length of ICU stay was prolonged in hypophosphatemic patients with respiratory failure. We suggested to follow the phosphate levels tightly for early diagnosis and treatment of phosphate deficiency. (Journal of the Turkish Society of Intensive Care 2011; 9: 19-22

    Full Text Available Objective: to reveal the factors that are responsible for the development of respiratory distress syndrome (RDS and the specific features of its course in preterm twin neonates. Subjects and methods. Twenty-three patients who had had twin pregnancy, including 9 (39.1% and 14 (60% with monochorial and bichorial biamniotic twin pregnancies, respectively, were examined. Their mean age was 28.5±5.4 years. Obstetric and gynecologic histories, conditions at conception, the course of pregnancy, the type of pla-centation, and fetal presentation were considered. The placentas were morphologically examined. In all the patients, pregnancy ended in birth of 46 premature neonates, of them there were 19 (41.3% boys and 27 (58.7% girls. The gestational age of the neonates averaged 31.7±2.3 weeks. The evaluation of the efficiency of performed therapy used clinical assessment of the status of the premature neonates; measurement of partial oxygen tension (pO2 and calculation of alveolar-arterial oxygen gradient (A-a DO2, respiratory index (RI, and oxygenation index (OI; death rates were analyzed. Results. The main cause of respiratory failure (RF was RDS in premature twins. Neonatal blood aspiration-caused pneumonia occurred in one case. The course of RDS was variable. Most neonatal infants needed exogenous surfactant replacement therapy and mechanical ventilation (MV. No signs of RF were present in 7 (15.2% premature neonates. Conclusion. Premature twins are a high RDS risk group. The unfavorable factors that contribute to the development of the disease are multiple pregnancy, a past maternal obstetric history, in-vitro fertilization-induced pregnancy, severe gestosis in the second half of pregnancy, and preterm delivery. The type of placentation affects the fetal status after birth. Fatal outcome occurred in infants from the monochorial bioamniotic twins. In multiple pregnancies, there are pathological changes in the placenta, its membranes, and umbilical

    A syndrome consisting of a rigid spine and myopathy predominantly affecting proximal limb muscles has been previously described in children, and as with most neuromuscular disorders, the respiratory muscles appear to be affected only at an advanced stage in the disease. We describe an adult male with this syndrome who presented with ventilatory failure caused by severe respiratory muscle weakness and who demonstrated profound nocturnal arterial oxygen desaturation, particularly during rapid eye movement sleep. Treatment with negative pressure ventilation initially resulted in only modest improvements in symptoms, blood gas tensions, and nocturnal desaturation. The cause of this only partial improvement was upper airway obstruction provoked by the mode of ventilatory support used. After tracheostomy there was a dramatic and sustained improvement in symptoms and blood gas tensions and complete abolition of nocturnal arterial oxygen desaturation. This is the first report of an adult with the rigid spine syndrome presenting with ventilatory failure and cor pulmonale due to severe respiratory muscle weakness.

    Full Text Available Objectives. To investigate the effect of the cause of acute respiratory failure and the role of comorbidities both acute and chronic on the outcome of COPD patients admitted to Respiratory Intensive Care Unit (RICU with acute respiratory failure and treated with NIV. Design. Observational prospective study. Patients and Methods. 176 COPD patients consecutively admitted to our RICU over a period of 3 years and treated with NIV were evaluated. In all patients demographic, clinical, and functional parameters were recorded including the cause of acute respiratory failure, SAPS II score, Charlson comorbidity index, and further comorbidities not listed in the Charlson index. NIV success was defined as clinical improvement leading to discharge to regular ward, while exitus or need for endotracheal intubation was considered failure. Results. NIV outcome was successful in 134 patients while 42 underwent failure. Univariate analysis showed significantly higher SAP II score, Charlson index, prevalence of pneumonia, and lower serum albumin level in the failure group. Multivariate analysis confirmed a significant predictive value for pneumonia and albumin. Conclusions. The most important determinants of NIV outcome in COPD patients are the presence of pneumonia and the level of serum albumin as an indicator of the patient nutritional status.

    Full Text Available Human metapneumovirus (HMPV is a common virus that can cause respiratory problems ranging from mild upper respiratory tract disease to respiratory failure requiring mechanical support. Here, we report a case of a 32-month-old male with a previous history of asthma, who developed respiratory failure two weeks after onset of cough and rhinorrhea and required extracorporeal membrane oxygenation (ECMO for 9 days after failing high-frequency oscillatory ventilation (HFOV. To our knowledge, this is the oldest reported pediatric patient with respiratory failure secondary to human metapneumovirus that did not respond to mechanical ventilation. This case highlights three critical points: the potentially fatal causative role of HMPV in respiratory failure in an older pediatric age group of immunocompetent hosts, the importance of early recognition of impending respiratory failure, and the timely utilization of ECMO.

We evaluate the effects of RMT on the hemodynamic and autonomic function, arterial baroreflex sensitivity (BRS), and respiratory mechanics in rats with HF. Rats were assigned to one of four groups: sedentary sham (n = 8), trained sham (n = 8), sedentary HF (n = 8), or trained HF (n = 8). Trained animals underwent a RMT protocol (30 min/day, 5 day/wk, 6 wk of breathing through a resistor), whereas sedentary animals did not. In HF rats, RMT had significant effects on several parameters. It reduced left ventricular (LV) end-diastolic pressure (P RMT (P RMT (P RMT (P RMT protocol in HF rats promotes an improvement in hemodynamic function, sympathetic and vagal heart modulation, arterial BRS, and respiratory mechanics, all of which are benefits associated with improvements in cardiopulmonary interaction.

    Full Text Available Diffuse alveolar hemorrhage (DAH is associated with severe outcomes. We report a case of acute respiratory failure that required mechanical ventilation and was clinically and pathologically diagnosed as DAH related to exposure to organic dust. A 39-year-old man, who had visited a warehouse to grade beans for purchase, was referred to our hospital for impending respiratory failure. His initial radiographic examinations revealed diffuse bilateral ground-glass opacities in his lungs and bronchoalveolar lavage resulted in progressively bloodier returns, which is characteristic of DAH. He underwent bedside open lung biopsy of his right lower lobe in the intensive care unit. Biopsy results revealed DAH and organization with accumulation of hemosiderin-laden macrophages and a few fibroblastic foci. The patient was treated with empirical antibiotics and high-dose corticosteroids and successfully weaned from mechanical ventilation. DAH might be considered in the differential diagnosis of patients with acute respiratory failure after exposure to organic particles.

    Full Text Available INTRODUCTION: The transition from paternalistic medicine to a healthcare culture centred on the patient's decision making autonomy presents problems of communication and understanding. Chronic respiratory failure challenges patients, their families and caregivers with important choices, such as invasive and non-invasive mechanical ventilation and tracheostomy, which, especially in the case of neuromuscular diseases, can significantly postpone the end of life. MATERIAL AND METHODS: A 7-item questionnaire was administered to 100 patients with advanced COPD, neuromuscular diseases and pulmonary fibrosis, all of them on oxygen therapy and receiving day-hospital treatment for respiratory failure. The objective was to find out whether or not patients, if faced with a deterioration of their health condition, would want to take part in the decision making process and, if so, how and with whom. RESULTS. Results showed that: 90% of patients wanted to be interviewed, 10% preferred not to be interviewed, 82% wanted to be regularly updated on their clinical situation, 75% wanted to be intubated, if necessary, and 56% would also agree to have a tracheostomy. These choices have been confirmed one year later, with 93% of respondents accepting the questionnaire and considering it useful. CONCLUSIONS: It is possible to conclude that a simple questionnaire can be a useful tool contributing to therapeutic decision making in respiratory failure.

    To identify determinants of respiratory disease progression in late-onset Pompe disease (LOPD), we studied relationships between pulmonary function, respiratory muscle strength, gas exchange, and respiratory control. Longitudinal evaluation of 22 LOPD patients (mean age 38 years) was performed at 6-month intervals for 6-24 months. Measurements included vital capacity (VC), maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), tidal volume (VT), dead space (VD), and ventilatory response to CO2. Although reduction in VC correlated with MIP and MEP (p respiratory failure, is tightly linked to the degree of respiratory muscle weakness and severity of pulmonary dysfunction in LOPD patients. Reductions in CO2 clearance efficiency and ventilatory responsiveness may contribute to the development of chronic daytime hypercapnia.

    Acute respiratory failure caused by pulmonary tuberculosis is a rare event but with a high mortality even while receiving mechanical ventilatory support. We report the case of a young man with severe pulmonary tuberculosis refractory to conventional therapy who successfully overcame the critical period of his condition using noninvasive ventilation and immunoadjuvant therapy that included three doses of etanercept 25 mg subcutaneously. We conclude that the use of etanercept along with antituberculosis treatment appears to be safe and effective in patients with pulmonary tuberculosis presenting with acute respiratory failure.

    Velopharyngeal insufficiency (VPI) is an uncommon pediatric disorder often associated with congenital syndromes. After speech therapy, surgery is the standard management. Many surgical approaches to VPI repair have been reported and the complications of these procedures are well documented. To date, there have been no published cases of respiratory failure secondary to pneumomediastinum, pneumopericardium, and bilateral pneumothoraces with associated subcutaneous emphysema after superior-based pharyngeal flap. We present the first case in the literature. Our proposed etiology for the respiratory failure is air tracking from the flap donor site to the pleural spaces of the thoracic cavity via the visceral or prevertebral fascia following positive pressure ventilation.

    2007-01-01

    Full Text Available A 21-year-old primigravida, at 32 weeks of gestation, presented with acute onset of respiratory failure and circulatory shock. Chest imaging showed findings suggestive of ruptured hydatid cyst, which was confirmed by histology post-thoracotomy. Tissue cultures from the removed cyst grew Mycobacterium tuberculosis also. She was successfully managed in the intensive care unit and was then discharged home on antituberculosis medications in addition to albendazole after prolonged hospitalization and a need for chest tube for bronchopleural fistula. Acute respiratory failure and anaphylactic shock secondary to ruptured pulmonary hydatid cyst and superimposed pulmonary tuberculosis in a pregnant lady should be considered in patients living in endemic areas.

    2012-01-01

    Full Text Available Endoscopic third ventriculostomy (ETV is a relatively safe procedure. However, postoperative acute respiratory failure may be fatal. The authors report an 8-month-old patient with obstructive hydrocephalus secondary to posterior fossa cyst, and Chiari malformation. After ETV he developed difficulty in breathing, and had to be reintubated and ventilated. The infant recovered fully after craniocervical decompression and insertion of cystoperitoneal shunt. We speculate that respiratory failure is related to relative expansion of the posterior fossa arachnoid cyst, causing significant compression on the brain stem. Supportive care with mechanical ventilation and brain stem decompression were the mainstay of treatment.

    Congenital arteriovenous malformations (AVMs) of the thoracic region are rarely reported in adults. The authors report an unusual case of a 30-year-old man who presented with a large congenital AVM and heart failure. The diagnosis was made using transthoracic Doppler echocardiography and computed tomography. Embolization followed by surgical resection of the AVM resulted in the prompt relief of heart failure.

    Respiratory failure is associated with a high mortality rate in burned children. Recently, a specialized pulmonary enteral formula (SPEF) was commercially introduced as an adjunct intervention in acute lung injury management. SPEF contains condition-specific nutrients to modulate the inflammatory response. The study examined SPEF impact in critically ill, pediatric burn patients with respiratory failure. Medical records of acute burn patients admitted December 1997 to October 2006 were reviewed for SPEF treatment. Respiratory and renal indices were compared on the first and final days of SPEF use. Nineteen patients with respiratory failure received SPEF for a mean of 10.8 +/- 0.9 days during their acute burn course. Mean age was 5.3 +/- 1.5 years. Mean total body surface area burn was 44.3 +/- 5.4% with 32.5 +/- 6.4% full thickness. Patients were admitted 2.3 +/- 0.9 days postburn. Significant improvements in peak pressure, PEEP, FiO2, P:F ratio, Pco2, Po2, and ETco2 were noted. Seventeen of the 19 patients survived despite the fact that 9 of the 19 patients developed severe barotrauma requiring multiple tube thoracotomies, and all 19 had extremely poor prognoses at SPEF initiation. Adult SPEF formula for critically ill, pediatric burn patients with respiratory failure is safe and well tolerated. SPEF seems to facilitate recovery from acute lung injury as evidenced by improvements in oxygenation and pulmonary compliance.

    The critical care nurse can no longer view adult respiratory distress syndrome (ARDS) as a single organ dysfunction. ARDS may be the triggering event or the end result of a systemic inflammatory response. This article focuses on the research examining the cellular and humoral mediators precipitating the pathophysiologic processes seen in ARDS. An examination of assessment cues for early diagnosis and continued evaluation of the progression of acute lung injury and the systemic response are explored. Concluding the article is a critical analysis of supportive and experimental treatment modalities and their impact on patient outcome.

    Heading AbstractBackground. In patients with acute severe respiratory failure (ARF) treated with extracorporeal membrane oxygenation (ECMO) the radiological evaluation has until now almost exclusively relied on bedside radiography and US. At St. Goeran/Karolinska ECMO centre CT has become a routine complement to bedside examinations.Objective. To review retrospectively the frequency, indications and findings on CT of patients with ARF on ECMO and to evaluate the risk of complications associated with transportation for CT examinations.Materials and methods. One hundred twelve neonates, children and adults were treated with ECMO from May 1994 to January 2001. Forty-six per cent of these patients had CT examinations on one or more occasions during ECMO, giving a total number of 238 examination sites on 104 occasions. All CT examinations were performed in the Paediatric Radiology Department and included a 10-min transport using a mobile ECMO system.Results. CT was more often performed in older patients and in patients with long ECMO runs. The main indications were suspected complications of ECMO and/or the underlying disease or a delay in clinical improvement. In 57% of the CT occasions, significant findings affecting treatment were revealed. There were no complications associated with the examinations or transport.Conclusions. CT is safe and useful in evaluation of patients with ARF during ECMO. (orig.)

    We studied respiratory function and Chest Wall kinematics in a large population of adult patients affected by slow course muscular dystrophies such as Limb-Girdle Muscular Dystrophy (LGMD, n=38), Becker Muscular Dystrophy (BMD, n=20) and Facio-Scapulo Humeral Dystrophy (FSHD, n=30), through standard spirometry and through the Optoelectronic Plethysmography, to measure the thoraco-abdominal motion during Quiet Breathing and Slow Vital Capacity maneuvers. Within the restrictive pulmonary syndrome characterizing LGMD and FSHD, several different thoraco-abdominal patterns compared to those of healthy subjects were present in the more advanced stages of the disease. These differences were present in the seated position, during the execution of a maximal maneuver such as Slow Vital Capacity. A global respiratory (both inspiratory and expiratory) muscle involvement was more pronounced in the LGMD and FSHD than in the BMD patients, and a significant reduction of abdominal contribution in wheelchair bound patients was observed. In conclusion, OEP technique is able to reveal mild initial modifications in the respiratory muscles in FSHD and LGMD patients, which could be helpful for functional and new therapeutic strategy evaluation.

    Full Text Available Respiratory failure due to subglottic stenosis is a rare but serious condition. A 22-year-old male presented to the emergency department (ED with shortness of breath, stridor, and change in tone of voice. The patient did not complain of B-symptoms (fever, weight loss, and night sweats. In the week before this presentation, he was diagnosed with an upper respiratory tract infection with associated bronchospasm and discharged on oral antibiotics and inhaled salbutamol without effect. He developed hypercapnic respiratory failure in the ED after a coughing episode. A normal nasopharyngoscopic examination and a subtle mediastinal abnormality on chest radiograph lead to a working diagnosis of retrosternal subglottic obstruction. The complexities of his airway management and suggestions for multidisciplinary approach are discussed.

  9. [Learning from failure - implications for respiratory and intensive care medicine: a conceptual review].

    Kabitz, H-J

    2013-08-01

    The clinical, social and economical impact of failure in medicine [i. e., adverse health care events (AHCE)] is overwhelming. Respiratory and intensive care medicine are strongly relevant to AHCE, particularly in cases associated with respiratory failure, mechanical ventilation and pharmacotherapy. In spite of the obvious necessity to learn from AHCE, its realisation in health-care organisations is still rare. This conceptual review therefore aims to (i) clarify the most relevant terminology, (ii) identify obstacles related to this health-care topic, and (iii) present possible strategies for solving the problems, thereby enabling respiratory and intensive care medicine to systematically and effectively learn from failure. A review of the literature (effective as of June 2013) derived from the electronic databases Medline via PubMed, EMBASE, ERIC and Google Scholar identified the following relevant obstacles (ii): a so-called blame culture associated with concealing failure, missing system analyses (vs. individual breakdown), and (economically) misdirected incentives. Possible strategies to overcome these obstacles (iii) include acknowledging the importance of leadership, a safe environment, open reporting, an effective feedback culture, and detection (e. g., trigger-tools), analysis and discussion (e. g., double loop learning) of failure. The underlying reasons for the occurrence of AHCE are based on structural, organisational and human shortcomings, and affect all categories of caregivers. Approaches to solving the problem should therefore focus primarily on the entire system, rather than on the individual alone.

    Background:Stress index at post-recruitment maneuvers could be a method of positive end-expiratory pressure (PEEP) titration in acute respiratory distress syndrome (ARDS) patients.However,airway pressure (Paw) stress index may not reflect lung mechanics in the patients with high chest wall elastance.This study was to evaluate the Paw stress index on lung mechanics and the correlation between Paw stress index and transpulmonary pressure (PL) stress index in acute respiratory failure (ARF) patients.Methods:Twenty-four ARF patients with mechanical ventilation (MV) were consecutively recruited from July 2011 to April 2013 in Zhongda Hospital,Nanjing,China and Ospedale S.Giovanni Battista-Molinette Hospital,Turin,Italy.All patients underwent MV with volume control (tidal volume 6 ml/kg) for 20 min.PEEP was set according to the ARDSnet study protocol.The patients were divided into two groups according to the chest wall elastance/respiratory system elastance ratio.The high elastance group (H group,n =14) had a ratio ≥30%,and the low elastance group (L group,n =10) had a ratio <30%.Respiratory elastance,gas-exchange,Paw stress index,and PL stress index were measured.Student's t-test,regression analysis,and Bland-Altman analysis were used for statistical analysis.Results:Pneumonia was the major cause of respiratory failure (71.0%).Compared with the L group,PEEP was lower in the H group (5.7 ± 1.7 cmH2O vs.9.0 ± 2.3 cm2O,P < 0.01).Compared with the H group,lung elastance was higher (20.0 ± 7.8 cmH2O/L vs.11.6 ± 3.6 cmH2O/L,P < 0.01),and stress was higher in the L group (7.0 ± 1.9 vs.4.9 ± 1.9,P =0.02).A linear relationship was observed between the Paw stress index and the PL stress index in H group (R2 =0.56,P < 0.01) and L group (R2 =0.85,P < 0.01).Conclusion:In the ARF patients with MV,Paw stress index can substitute for PL to guide ventilator settings.

    Pneumonia refers to lung inflammation caused by different pathogens or other factors, and is a common pediatric disease occurring in infants and young children. It is closely related to the anatomical and physiological characteristics of infants and young children and is more frequent during winter and spring, or sudden changes in temperature. Pneumonia is a serious disease that poses a threat to children's health and its morbidity and mortality rank first, accounting for 24.5-65.2% of pediatric inpatients. Due to juvenile age, severe illness and rapid changes, children often suffer acute heart failure, respiratory failure and even toxic encephalopathy at the same time. The concurrence in different stages of the process of emergency treatment tends to relapse, which directly places the lives of these children at risk. Severe pneumonia constitutes one of the main causes of infant mortality. In the process of nursing children with severe pneumonia, intensive care was provided, including condition assessment and diagnosis, close observation of disease, keeping the airway unblocked, rational oxygen therapy, prevention and treatment of respiratory and circulatory failure, support of vital organs, complications, and health education. The inflammatory response was proactively controlled, to prevent suffocation and reduce mortality. In summary, positive and effective nursing can promote the rehabilitation of children patients, which can be reinforced with adequate communication with the parents and/or caretakers.

Although randomized controlled trials show lowered mortality rates in highly selected patients with acute exacerbation and respiratory failure, there are only few reports on long-term survival after receiving NIV. We present long-term all-cause mortality data from patients receiving NIV for the first time. Method: Data from medical records were retrospectively retrieved from all patients receiving NIV for the first time after being admitted acutely to an acute medical ward and further transfer to a respiratory ward with respiratory failure and a diagnosis of COPD in the period January 1, 2005 to December 31, 2007; patients were followed until January 2012. Demographic data collected included age, sex, diagnoses at discharge, and, when present, FEV1; a “not-to-intubate” order was also registered when listed. Results: In total, 253 patients (143 female, 110 male received NIV for the first time. The median age was 72 years (range 46–91 years. The 30-day mortality rate was 29.3%. The 5-year survival rate was 23.7%. Women showed a trend towards better survival than men (25.7% vs 19.2%, P = 0.25, and the trend was even more pronounced for patients with COPD. Conclusion: The mortality rate of patients receiving NIV is high, as expected in a real-life setting, but with a 5-year survival rate

    Full Text Available Guillain-Barré syndrome (GBS is a rare entity in infants. We report a case of GBS in a 5-month-old girl. The child presented with cough, loose stools, breathing difficulty, and listlessness. The child was treated as pneumonia with respiratory failure. Due to difficulty in weaning from ventilation with areflexia, marked hypotonia, and reduced power in all four limbs; possibilities of spinal muscular atrophy, poliomyelitis, and myopathies were kept. Nerve conduction velocity study was suggestive of mixed sensory-motor, severe axonal, and demyelinating polyradiculoneuropathy. Cerebrospinal fluid study revealed albuminocytological dissociation. Child was diagnosed as GBS and treated with intravenous immunoglobulin. Child recovered completely on follow-up. GBS should be considered as a differential diagnosis in acute onset respiratory failure with neuromuscular weakness in infants.

    A number of video-assisted thoracoscopic surgery (VATS) procedures are being increasingly performed by awake anesthesia in an attempt of minimizing the surgical- and anesthesia-related traumas. However, so far the usefulness of awake VATS for urgent management of retained haemothorax has been scarcely investigated. Herein we present two patients with retained haemothorax following previous thoracentesis and blunt chest trauma, respectively, who developed acute respiratory failure and underwen...

  18. Respiratory failure induced by acute organophosphate poisoning in rats: effects of vagotomy.

    Acute organophosphate (OP) poisoning causes respiratory failure through two mechanisms: central apnea and pulmonary dysfunction. The vagus nerve is involved in both the central control of respiratory rhythm as well as the control of pulmonary vasculature, airways and secretions. We used a rat model of acute OP poisoning with and without a surgical vagotomy to explore the role of the vagus in OP-induced respiratory failure. Dichlorvos (2,2-dichlorovinyl dimethyl phosphate) injection (100mg/kg subcutaneously, 3 x LD50) resulted in progressive hypoventilation and apnea in all animals, irrespective of whether or not the vagi were intact. However, vagotomized animals exhibited a more rapidly progressive decline in ventilation and oxygenation. Artificial mechanical ventilation initiated at onset of apnea resulted in improvement in oxygenation and arterial pressure in poisoned animals with no difference between vagus intact or vagotomized animals. Our observations suggest that vagal mechanisms have a beneficial effect during the poisoning process. We speculate that vagally mediated feedback signals from the lung to the brainstem serve as a modest protective mechanism against central respiratory depressive effects of the poison and that bulbar-generated efferent vagal signals do not cause sufficient pulmonary dysfunction to impair pulmonary gas exchange.

    Our objective was to characterize our experience with 8 patients with Rett syndrome undergoing scoliosis surgery in regard to rates of respiratory failure and rates of ventilator-acquired pneumonia in comparison to patients with neurologic scoliosis and adolescent idiopathic scoliosis. This study was a retrospective chart review of patients undergoing scoliosis surgery at a tertiary children's hospital. Patients were divided into 3 groups: (1) adolescent idiopathic scoliosis, (2) neurologic scoliosis, and (3) Rett syndrome. There were 133 patients with adolescent idiopathic scoliosis, 48 patients with neurologic scoliosis, and 8 patients with Rett syndrome. We found that patients with Rett syndrome undergoing scoliosis surgery have higher rates of respiratory failure and longer ventilation times in the postoperative period when compared with both adolescent idiopathic scoliosis and neurologic scoliosis patients. There is insufficient evidence to suggest a difference in the incidence of ventilator-acquired pneumonia between the Rett syndrome and the neurologic scoliosis group. We believe our findings are the first in the literature to show a statistically significant difference between these 3 groups in regard to incidence of respiratory failure.

    Neuromuscular diseases affect alveolar air exchange and therefore cause chronic respiratory failure. The onset of respiratory failure can be acute, as in traumas, or progressive (slow or rapid), as in amyotrophic lateral sclerosis, muscular dystrophies, diseases of the myoneural junction, etc. Respiratory muscle impairment also affects cough efficiency and, according to the current knowledge regarding the type of treatment available in Brazil to these patients, it can be said that the high rates of morbidity and mortality in these individuals are more often related to the fact that they cough inefficiently rather than to the fact that they ventilate poorly. In this review, with the objective of presenting the options of devices available to support and substitute for natural ventilation in patients with neuromuscular diseases, we have compiled a brief history of the evolution of orthopedic braces and prostheses used to aid respiration since the end of the 19th century. In addition, we highlight the elements that are fundamental to the diagnosis of alveolar hypoventilation and of failure of the protective cough mechanism: taking of a clinical history; determination of peak cough flow; measurement of maximal inspiratory and expiratory pressures; spirometry in two positions (sitting and supine); pulse oximetry; capnography; and polysomnography. Furthermore, the threshold values available in the literature for the use of nocturnal ventilatory support and for the extension of this support through the daytime period are presented. Moreover, the maneuvers used to increase cough efficiency, as well as the proper timing of their introduction, are discussed.

    Full Text Available Purpose. Venoarterial extracorporeal membrane oxygenation (VA-ECMO is known to improve cardiorespiratory function and outcome in neonates with severe respiratory failure. We tested the hypothesis that VA-ECMO therapy improves the microcirculation in neonates with severe respiratory failure. Methods. This single-center prospective observational pilot study took place in an intensive care unit of a level III university children’s hospital. Twenty-one-term neonates, who received VA-ECMO treatment, were included. The microcirculation was assessed in the buccal mucosa, using Orthogonal Polarization Spectral imaging, within 24 hours before (T1 and within the first 24 hours after initiation of ECMO treatment (T2. Data were compared to data of a ventilated control group (=7. Results. At baseline (T1, median functional capillary density (FCD, microvascular flow index (MFI, and heterogeneity index (HI did not differ between the ECMO group and the control group. At T2 the median FCD was lower in the control group (median [range]: 2.4 [1.4–4.2] versus 4.3 [2.8–7.4] cm/cm2; P value <0.001. For MFI and HI there were no differences at T2 between the two groups. Conclusion. The perfusion of the microcirculation does not change after initiation of VA-ECMO treatment in neonates with severe respiratory failure.

    Full Text Available Background and Purpose : A water decoction of the poisonous shrub Cleistanthus collinus is used for suicidal purposes. The mortality rate is 28%. The clinical profile includes distal renal tubular acidosis (DRTA and respiratory failure. The mechanism of toxicity is unclear. Objectives : To demonstrate features of C. collinus toxicity in a rat model and to identify its mechanism(s of action. Materials and Methods : Rats were anesthetized and the carotid artery was cannulated. Electrocardiogram and respiratory movements were recorded. Either aqueous extract of C. collinus or control solution was administered intraperitoneally. Serial measurements of blood gases, electrolytes and urinary pH were made. Isolated brush border and basolateral membranes from rat kidney were incubated with C. collinus extract and reduction in ATPase activity was assessed. Venous blood samples from human volunteers and rats were incubated with an acetone extract of C. collinus and plasma potassium was estimated as an assay for sodium-potassium pump activity. Results : The mortality was 100% in tests and 17% in controls. Terminal event in test animals was respiratory arrest. Controls had metabolic acidosis, respiratory compensation , acidic urine and hyperkalemia. Test animals showed respiratory acidosis, alkaline urine and low blood potassium as compared to controls. C. collinus extract inhibited ATPase activity in rat kidney. Plasma K + did not increase in human blood incubated with C. collinus extract. Conclusions and Implications : Active principles of C. collinus inhibit proton pumps in the renal brush border, resulting in type I DRTA in rats. There is no inhibition of sodium-potassium pump activity. Test animals develop respiratory acidosis, and the immediate cause of death is respiratory arrest.

    Sea drowning is a common cause of accidental death worldwide. Respiratory complications such as acute pulmonary oedema, which is often complicated by acute respiratory distress syndrome, is often seen. Noninvasive ventilation is already widely used as a first approach to treat acute respiratory failure resulting from multiple diseases. We report a case of a 45 year old man with a history of epilepsy, motor and mental handicap who developed acute respiratory failure secondary to sea water drowning after an epileptic crisis. We illustrate successful and rapid management of this case with noninvasive ventilation. We emphasize the advantages and limitations of using noninvasive ventilation to treat acute respiratory failure due to sea water drowning syndrome.

    Background Infection due to pandrug-resistant Pseudomonas aeruginosa (PDRPA) has become a challenge in clinical practice. The aim of this research was to summarize the treatment of large-area burns (60%-80%) with PDRPA infection and respiratory failure in our hospital over the last two years, and to explore a feasible treatment protocol for such patients.Methods We retrospectively analyzed the treatment of five patients with large-area burns accompanied by PDRPA infection and respiratory failure transferred to our hospital from burn units in hospitals in other Chinese cities from January 2008 to February 2010. Before PDRPA infection occurred, all five patients had open wounds with large areas of granulation because of the failure of surgery and dissolving of scar tissue; they had also undergone long-term administration of carbapenems. This therapy included ventilatory support, rigorous repair of wounds, and combined antibiotic therapy targeted at drug-resistance mechanisms, including carbapenems, ciprofloxacin, macrolide antibiotics and β-lactamase inhibitors.Results Four patients recovered from bums and one died after therapy.Conclusions First, compromised immunity caused by delayed healing of burn wounds in patients with large-area bums and long-term administration of carbapenems may be the important factors in the initiation and progression of PDRPA infection. Second, if targeted at drug-resistance mechanisms, combined antibiotic therapy using carbapenems,ciprofloxacin, macrolide antibiotics and β-lactamase inhibitors could effectively control PDRPA infection. Third, although patients with large-area burns suffered respiratory failure and had high risks from anesthesia and surgery, only aggressive skin grafting with ventilatory support could control the infection and save lives. Patients may not be able to tolerate a long surgical procedure, so the duration of surgery should be minimized, and the frequency of surgery increased.

    Extracorporeal membrane oxygenation (ECMO) is an important rescue therapy for patients with cardiac and/or respiratory failure, with a growing body of literature supporting its use. Despite widespread use of ECMO, there remains a paucity of data on optimal management strategies for ECMO patients. Management of ECMO patients involves an understanding of the complex interaction between this technology and the critically ill patients being supported. ECMO providers typically rely on a combination of consensus guidelines and institutional experience to make management decisions. Substantial controversy continues to exist regarding many elements of ECMO management, including seemingly straightforward decisions such as the initial implementation of this technology. In addition, there are multiple providers involved in the management of ECMO patients who must be co-ordinated for this supportive therapy to be most effective. This manuscript provides an overview of current techniques for treating respiratory ECMO patients.

    Full Text Available Licorice is the root of Glycyrrhiza glabra, which has a herbal ingredient, glycyrrhizic acid. Excessive intake of licorice may cause a hypermineralocorticoidism-like syndrome characterized by sodium and water retention, hypokalemia, hypertension, metabolic alkalosis, low-renin activity, and hypoaldosteronism. In this paper, an 34 years old man who admitted to the emergency department with respiratory failure and marked muscle weakness of all extremities that progressed to paralysis after excessive intake of licorice syrup was presented. It was aimed to draw attention to the necessity of questioning whether there is excessive intake of licorice or not in patients who admitted to emergency department with paralysis and dyspnea. Plasma potassium concentration of the patient was 1.4 mmol/L. The patient\\'s respiratory distress and loss of muscle strength recovered completely after potassium replacement.

    We report a case of acute respiratory failure due to refeeding syndrome caused by hypocaloric enteral tube feeds. A 60-y-old obese man, with a diagnosis of esophageal carcinoma with local metastases, underwent feeding jejunostomy tube insertion. Enteral tube feeding was initiated at small volumes providing 4.4 kcal x kg(-1) x d(-1) and gradually increased over 48 h to 29 kcal x kg(-1) x d(-1) (based on adjusted body weight). The patient then developed acute respiratory distress requiring intubation and ventilatory support. Serum phosphorus (P) level was extremely low at 4 d to adequately correct the electrolyte derangements. Successful liberation from mechanical ventilation was then possible. In chronically malnourished patients undergoing nutritional support, even hypocaloric feeding should be considered a risk factor for developing refeeding syndrome leading to severe and acute electrolyte fluid-balance and metabolic abnormalities.

We report herein the successful treatment of severe respiratory failure in two patients with urorectal septum malformation sequence and prenatally diagnosed oligohydramnios. The patients showed significant hypoxic deterioration and persistent pulmonary artery hypertension soon after birth. We used high-frequency ventilation (HFO, nitric oxide (NO, and extracorporeal membrane oxygenation (ECMO. The patients were successfully weaned from ECMO and artificial ventilation and discharged to home. Although termination of the pregnancy has often been selected for fetuses with oligohydramnios-related urorectal septum malformation sequence, our results suggest the opportunity for these fetuses to be treated using respiratory supports including HFO, NO, and ECMO after birth.

    2011-03-01

    Full Text Available Non invasive positive pressure ventilation (NPPV is increasingly used for patients with hypercapnic respiratory failure secondary to acute exacerbation of chronic obstructive pulmonary disease (COPD. NPPV has been shown to improve arterial blood gas tensions and dyspnoea and to prevent the need for intubation in patients admitted to hospital with an exacerbation of COPD associated with respiratory acidosis. Although advantages of NPPV over conventional treatment have been convincingly documented in the short period, there are fewer data as to the outcomes following hospital discharge. We have undertaken a prospective descriptive study to obtain comprehensive data on the in hospital and 3 month outcomes of a cohort of 57 COPD patients treated with NPPV for acute hypercapnic respiratory failure as a first intervention in addition to usual medical care. Patients with a COPD exacerbation had better outcomes than patients with COPD complicated by other acute conditions. Pneumonia was specifically associated with a higher inhospital risk of death. In our series about one in four patients with an indicator of previous severe respiratory disease (past admission for acute respiratory failure, previous use of NPPV, long term oxygen therapy or home NPPV was dead at three months after discharge and almost one in two was dead or had been readmitted. On the contrary, patients without indicators of previous severe respiratory disease benefited from NPPV during an acute episode of respiratory failure and had a chance of approximately 80% of being alive and free from recurrence at three months.

    Kosky, Christopher; Turton, Charles

    2006-01-01

    Acute hypercapnic respiratory failure in chronic obstructive pulmonary disease can usually be managed initially with medical treatment and non- invasive ventilation. In circumstances where non- invasive ventilation cannot be used or has failed, intubation and invasive ventilation may be lifesaving. The outcome of patients with an exacerbation of COPD requiring invasive ventilation is better than often thought, with a hospital survival of 70-89%. Decisions regarding invasive ventilation made by physicians and patients with COPD are unpredictable and vary with the individual. This article reviews the role of invasive ventilation in exacerbations of COPD to assist decision making.

    Callister, T Brian

    The successful treatment of a patient with acute respiratory failure is a complex undertaking that requires clinical competence, evidence-based interventions, seamless coordination of care transitions, and transparent open communication among all members of the health care team. Many of the processes of care in these critically ill patients are reassuringly consistent across services, across hospitals, across health systems, and even across the country. Although the clinical course of such complicated patients can be extremely unpredictable, we are fortunate that the professional, technical, and psychosocial aspects of care for these patients can be relatively orderly, evidence-based, and transparent.

  2. Noninvasive ventilation for acute respiratory failure: state of the art (II part

    Directory of Open Access Journals (Sweden)

    Federico Lari

    2013-04-01

    Full Text Available Background: In the last years Non-Invasive Ventilation (NIV has been playing an important role in the treatment of Acute Respiratory Failure (ARF. Prospective randomised controlled trials have shown improvements in clinical features (respiratory rate, neurological score, pH and arterial blood gases and in particular clinical conditions (Acute Cardiogenic Pulmonary Edema, ACPE, and acute exacerbation of Chronic Obstructive Pulmonary Disease, COPD systematic reviews and metha-analysis confirm a reduction in the need for intubation and in-hospital mortality compared to standard medical treatment. Methods: The most important techniques of ventilation in spontaneous breathing are: Continuous Positive Airway Pression (CPAP, usually performed with Venturi-like flow generators, and bi-level positive pressure ventilation (an high inspiratory pressure and a low expiratory pressure, performed with ventilators. Facial mask rather than nasal mask is used in ARF: the helmet is useful for prolonged treatments. Results: NIV’s success seems to be determined by early application, correct selection of patients and staff training. Controindications to NIV are: cardiac or respiratory arrest, a respiratory rate < 12 per minute, upper airway obstruction, hemodynamic instability or unstable cardiac arrhythmia, encephalopathy (Kelly score > 3, facial surgery trauma or deformity, inability to cooperate or protect the airway, high risk of aspiration and an inability to clear respiratory secretions. Conclusions: Bi-level ventilation for ARF due to COPD and CPAP or bi-level bentilation for ARF due to ACPE are feasible, safe and effective also in a General Medical ward if the selection of patients, the staff’s training and the monitoring are appropriate: they improve clinical parameters, arterial blood gases, prevent ETI, decrease mortality and hospitalisation. This should encourage the diffusion of NIV in this specific setting.

    Full Text Available The use of non-invasive ventilation (NIV in severe hypoxemic respiratory failure (PaO2/FIO2 ≤250 due to H1H1 virus pneumonia is controversial. In this prospective study, we aimed to assess the efficacy of NIV in avoiding endotracheal intubation and to identify predictors of success or failure. Nineteen patients with H1N1 viral pneumonia had severe respiratory failure (PaO2/FIO2 ratio ≤250. Five patients with PaO2/FIO2 lower than 150 and simplified acute physiology score (SAPS II lower than 34 underwent NIV and were admitted to the Intensive Care Unit and received NIV as first-line therapy. NIV failed in 2 of the 14 patients but had a good outcome in 12. None of the patients treated with NIV died. The duration of NIV was 5.0±1.9 days and the hospital stay was 11.3±1.2 days. The average PaO2/FIO2 ratio after 1 h of NIV was 239.1+38.7. No patient had multi-organ failure. PaO2/FIO2 ratio after 1 h and SAPS II at admission were independent variables correlated with the success of NIV. In our study, NIV was successful in 12 of the 14 patients (85.7% and this is one of the highest success rates in the literature. In our opinion, the reason for these results is the strict selection of patients with severe respiratory failure (PaO2/FIO2 ratio ≥150 and the strict following of predictors of success for NIV such as SAPS II of 34 or lower and PaO2/FIO2 ratio of 175 or lower after 1 h of NIV. Clinicians should be aware of pulmonary complications of influenza A H1N1 and strictly select the patients to undergo NIV. NIV could have an effective and safe role in reducing the high demand for critical care beds, particularly during the pandemic.

    Conventionally, a substantial number of patients with acute respiratory failure require mechanical ventilation (MV) to avert catastrophe of hypoxemia and hypercapnia. However, mechanical ventilation per se can cause lung injury, accelerating the disease progression. Extracorporeal membrane oxygenation (ECMO) provides an alternative to rescue patients with severe respiratory failure that conventional mechanical ventilation fails to maintain adequate gas exchange. The physiology behind ECMO and its interaction with MV were reviewed. Next, we discussed the timing of ECMO initiation based on the risks and benefits of ECMO. During the running of ECMO, the protective ventilation strategy can be employed without worrying about catastrophic hypoxemia and carbon dioxide retention. There is a large body of evidence showing that protective ventilation with low tidal volume, high positive end-expiratory pressure, and prone positioning can provide benefits on mortality outcome. More recently, there is an increasing popularity on the use of awake and spontaneous breathing for patients undergoing ECMO, which is thought to be beneficial in terms of rehabilitation.

    Full Text Available Treatment of Type II Respiratory Failure in a COPD patient is a difficult task for the ICU and Pulmonary physician. Multi factorial and multi - disciplinary approach is required . Our experience of two cases treated recently in Katuri medical College Hospita l have common features. One is a male of 54 years age and the other is a female of similar age. Both of them were obese and were nonsmokers. Both were poor and could not afford any ICU treatment on their own. Both were rescued by State sponsored Arogyasree programme. Both of them had the advantage of support from their families. Aided by Arogyasree programme, dedicated staff of ICU, Pulmonology, ENT departments , timely interventions with electrolyte balance, balanced antibiotic therapy, Noninvasive and inva sive ventilator strategies, Nutritional support, Blood transfusions, Timely Tracheostomy and excellent nursing care and drug administration in ICU both patients recovered back to normalcy . Initially both required home oxygen therapy and both were subsequen tly seen maintaining normal oxygenation status even without oxygen causing happiness to family members and the treating physicians

    Inhaled nitric oxide (INO) is a colorless, odorless gas that is also a potent pulmonary vasodilator. When given via the inhaled route it is a selective pulmonary vasodilator. INO is approved by the United States Food and Drug Administration (FDA) for the treatment of term and near-term neonates with hypoxemic respiratory failure associated with clinical or echocardiographic evidence of pulmonary arterial hypertension. A systematic review of the literature was conducted with the intention of making recommendations related to the clinical use of INO for its FDA-approved indication. Specifically, we wrote these evidence-based clinical practice guidelines to address the following questions: (1) What is the evidence for labeled use? (2) What are the specific indications for INO for neonates with acute hypoxemic respiratory failure? (3) Does the use of INO impact oxygenation, mortality, or utilization of extracorporeal membrane oxygenation (ECMO)? (4) Does INO affect long-term outcomes? (5) Is INO cost-effective therapy? (6) How is the appropriate dosing regimen and dose response to INO established? (7) How is the dose of INO titrated and weaned? (8) Which INO delivery system should be used? (9) How should INO be implemented with different respiratory support devices? (10) What adverse effects of INO should be monitored, and at what frequency? (11) What physiologic parameters should be monitored during INO? (12) Is scavenging of gases necessary to protect the caregivers? Using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) scoring system, 22 recommendations are developed for the use of INO in newborns.

    Oscar E Larios

    Full Text Available BACKGROUND: The gold standard for respiratory virus testing is a nasopharyngeal (NP swab, which is collected by a healthcare worker. Midturbinate (MT swabs are an alternative due to their ease of collection and possible self-collection by patients. The objective of this study was to compare the respiratory virus isolation of flocked MT swabs compared to flocked NP swabs. METHODS: Beginning in October 2008, healthy adults aged 18 to 69 years were recruited into a cohort and followed up for symptoms of influenza. They were asked to have NP and MT swabs taken as soon as possible after the onset of a fever or two or more respiratory symptoms with an acute onset. The swabs were tested for viral respiratory infections using Seeplex® RV12 multiplex PCR detection kit. Seventy six pairs of simultaneous NP and MT swabs were collected from 38 symptomatic subjects. Twenty nine (38% of these pairs were positive by either NP or MT swabs or both. Sixty nine (91% of the pair results were concordant. Two samples (3% for hCV OC43/HKU1 and 1 sample (1% for rhinovirus A/B were positive by NP but negative by MT. One sample each for hCV 229E/NL63, hCV OC43/HKU1, respiratory syncytial virus A, and influenza B were positive by MT but negative by NP. CONCLUSIONS: Flocked MT swabs are sensitive for the diagnosis of multiple respiratory viruses. Given the ease of MT collection and similar results between the two swabs, it is likely that MT swabs should be the preferred method of respiratory cell collection for outpatient studies. In light of this data, larger studies should be performed to ensure that this still holds true and data should also be collected on the patient preference of collection methods.

    Background Acute hypoxemic respiratory failure (AHRF) often develops acute respiratory distress syndrome (ARDS),and its incidence and mortalities in critically ill pediatric patients in China were 2% and 40% respectively.This study aimed at prospectively investigating incidence,causes,mortality and its risk factors,and any relationship to initial tidal volume (VT) levels of mechanical ventilation,in children ≤5 years of age with AHRF and ARDS.Methods In 12 consecutive months in 23 pediatric intensive care units (PICU),AHRF and ARDS were identified in those requiring >12 hour intratracheal mechanical ventilation and followed up for 90 days or until death or discharge.ARDS was diagnosed according to the American-European Consensus definitions.The mortality and ventilation free days (VFD) were measured as the primary outcome,and major complications,initial disease severity,and burden were measured as the secondary outcome.Results In 13 491 PICU admissions,there were 439 AHRE,of which 345 (78.6%) developed ARDS,resulting in incidences of 3.3% and 2.6%,and corresponding mortalities of 30.3% and 32.8% respectively along with 8.2 and 6.7 times of relative risk of death in those with pneumonia (62.9%) and sepsis (33.7%) as major underlying diseases respectively.No association was found in VT levels during the first 7 days with mortality,nor for VT at levels <6,6-8,8-10,and >10 ml/kg in the first 3 days with mortality or length of VFD.By binary Logistic regression analyses,higher pediatric risk of mortality score Ⅲ,higher initial oxygenation index,and age <1 year were associated with higher mortality or shorter VFD in AHRF.Conclusions The incidence and mortalities of AHRF and ARDS in children ≤5 years were similar to or lower than the previously reported rates (in age up to 15 years),associated with initial disease severity and other confounders,but causal relationship for the initial VT levels as the independent factor to the major outcome

    Acute respiratory distress syndrome (ARDS) continues to have significant mortality and morbidity. The only intervention proven to reduce mortality is the use of lung-protective mechanical ventilation strategies, although such a strategy may lead to problematic hypercapnia. Extracorporeal carbon dioxide removal (ECCO₂R) devices allow uncoupling of ventilation from oxygenation, thereby removing carbon dioxide and facilitating lower tidal volume ventilation. We performed a systematic review to assess efficacy, complication rates, and utility of ECCO₂R devices. We included randomised controlled trials (RCTs), case-control studies and case series with 10 or more patients. We searched MEDLINE, Embase, LILACS (Literatura Latino Americana em Ciências da Saúde), and ISI Web of Science, in addition to grey literature and clinical trials registries. Data were independently extracted by two reviewers against predefined criteria and agreement was reached by consensus. Outcomes of interest included mortality, intensive care and hospital lengths of stay, respiratory parameters and complications. The review included 14 studies with 495 patients (two RCTs and 12 observational studies). Arteriovenous ECCO₂R was used in seven studies, and venovenous ECCO₂R in seven studies. Available evidence suggests no mortality benefit to ECCO₂R, although post hoc analysis of data from the most recent RCT showed an improvement in ventilator-free days in more severe ARDS. Organ failure-free days or ICU stay have not been shown to decrease with ECCOvR. Carbon dioxide removal was widely demonstrated as feasible, facilitating the use of lower tidal volume ventilation. Complication rates varied greatly across the included studies, representing technological advances. There was a general paucity of high-quality data and significant variation in both practice and technology used among studies, which confounded analysis. ECCO₂R is a rapidly evolving technology and is an efficacious treatment

  11. Technical-Induced Hemolysis in Patients with Respiratory Failure Supported with Veno-Venous ECMO - Prevalence and Risk Factors.

    Full Text Available The aim of the study was to explore the prevalence and risk factors for technical-induced hemolysis in adults supported with veno-venous extracorporeal membrane oxygenation (vvECMO and to analyze the effect of hemolytic episodes on outcome. This was a retrospective, single-center study that included 318 adult patients (Regensburg ECMO Registry, 2009-2014 with acute respiratory failure treated with different modern miniaturized ECMO systems. Free plasma hemoglobin (fHb was used as indicator for hemolysis. Throughout a cumulative support duration of 4,142 days on ECMO only 1.7% of the fHb levels were above a critical value of 500 mg/l. A grave rise in fHb indicated pumphead thrombosis (n = 8, while acute oxygenator thrombosis (n = 15 did not affect fHb. Replacement of the pumphead normalized fHb within two days. Neither pump or cannula type nor duration on the first system was associated with hemolysis. Multiple trauma, need for kidney replacement therapy, increased daily red blood cell transfusion requirements, and high blood flow (3.0-4.5 L/min through small-sized cannulas significantly resulted in augmented blood cell trauma. Survivors were characterized by lower peak levels of fHb [90 (60, 142 mg/l] in comparison to non-survivors [148 (91, 256 mg/l, p≤0.001]. In conclusion, marked hemolysis is not common in vvECMO with modern devices. Clinically obvious hemolysis often is caused by pumphead thrombosis. High flow velocity through small cannulas may also cause technical-induced hemolysis. In patients who developed lung failure due to trauma, fHb was elevated independantly of ECMO. In our cohort, the occurance of hemolysis was associated with increased mortality.

    The improved survival in people with cystic fibrosis has led to an increasing number of patients reaching adulthood. This trend is likely to be maintained over the next decades, suggesting a need to increase the number of centres with expertise in the management of adult patients with cystic fibrosis. These centres should be capable of delivering multidisciplinary care addressing the complexity of the disease, in addition to addressing the psychological burden on patients and their families. Further issues that require attention are organ transplantation and end of life management.Lung disease in adults with cystic fibrosis drives most of the clinical care requirements, and major life-threatening complications, such as respiratory infection, respiratory failure, pneumothorax and haemoptysis, and the management of lung transplantation require expertise from trained respiratory physicians. The taskforce therefore strongly reccommends that medical leadership in multidisciplinary adult teams should be attributed to a respiratory physician adequately trained in cystic fibrosis management.The task force suggests the implementation of a core curriculum for trainees in adult respiratory medicine and the selection and accreditation of training centres that deliver postgraduate training to the standards of the HERMES programme.

    Full Text Available The Guillain-Barré syndrome (GBS is an acute post-infective autoimmune polyradiculoneuropathy, it is the commonest peripheral neuropathy causing respiratory failure. The aim of the study is to use the New Combined Scoring System in anticipating respiratory failure in order to perform elective measures without waiting for emergency situations to occur.
    Patients and methods: Fifty patients with GBS were studied. Eight clinical parameters (including progression of patients to maximum weakness, respiratory rate/minute, breath holding
    count (the number of digits the patient can count in holding his breath, presence of facial muscle weakness (unilateral or bilateral, presence of weakness of the bulbar muscle, weakness of the neck flexor muscle, and limbs weakness were assessed for each patient and a certain score was given to
    each parameter, a designed combined score being constructed by taking into consideration all the above mentioned clinical parameters. Results and discussion: Fifteen patients (30% that were enrolled in our study developed respiratory failure. There was a highly significant statistical association between the development of respiratory failure and the lower grades of (bulbar muscle weakness score, breath holding count scores, neck muscle weakness score, lower limbs and upper limbs weakness score , respiratory rate score and the total sum score above 16 out of 30 (p-value=0.000 . No significant statistical difference was found regarding the progression to maximum weakness (p-value=0.675 and facial muscle weakness (p-value=0.482.
    Conclusion: The patients who obtained a combined score (above 16’30 are at great risk of having respiratory failure.

    Background. Few studies have prospectively assessed viral etiologies of acute respiratory infections in community-based elderly individuals. We assessed viral respiratory pathogens in individuals ≥65 years with influenza-like illness (ILI). Methods. Multiplex reverse-transcriptase polymerase chain reaction identified viral pathogens in nasal/throat swabs from 556 episodes of moderate-to-severe ILI, defined as ILI with pneumonia, hospitalization, or maximum daily influenza symptom severity score (ISS) >2. Cases were selected from a randomized trial of an adjuvanted vs nonadjuvanted influenza vaccine conducted in elderly adults from 15 countries. Results. Respiratory syncytial virus (RSV) was detected in 7.4% (41/556) moderate-to-severe ILI episodes in elderly adults. Most (39/41) were single infections. There was a significant association between country and RSV detection (P = .004). RSV prevalence was 7.1% (2/28) in ILI with pneumonia, 12.5% (8/64) in ILI with hospitalization, and 6.7% (32/480) in ILI with maximum ISS > 2. Any virus was detected in 320/556 (57.6%) ILI episodes: influenza A (104/556, 18.7%), rhinovirus/enterovirus (82/556, 14.7%), coronavirus and human metapneumovirus (each 32/556, 5.6%). Conclusions. This first global study providing data on RSV disease in ≥65 year-olds confirms that RSV is an important respiratory pathogen in the elderly. Preventative measures such as vaccination could decrease severe respiratory illnesses and complications in the elderly. PMID:24482398

    Wan C Tan

    Full Text Available BACKGROUND: The relationship between patient-reported symptoms and objective measures of lung function is poorly understood. AIM: To determine the association between responsiveness to bronchodilator and respiratory symptoms in random population samples. METHODS: 4669 people aged 40 years and older from 8 sites in Canada completed interviewer-administered respiratory questionnaires and performed spirometry before and after administration of 200 ug of inhaled salbutamol. The effect of anthropometric variables, smoking exposure and doctor-diagnosed asthma (DDA on bronchodilator responsiveness in forced expiratory volume in 1 second (FEV1 and in forced vital capacity (FVC were evaluated. Multiple logistic regression was used to test for association between quintiles of increasing changes in FEV1 and in FVC after bronchodilator and several respiratory symptoms. RESULTS: Determinants of bronchodilator change in FEV1 and FVC included age, DDA, smoking, respiratory drug use and female gender [p<0.005 to p<0.0001 ]. In subjects without doctor-diagnosed asthma or COPD, bronchodilator response in FEV1 was associated with wheezing [p for trend<0.0001], while bronchodilator response for FVC was associated with breathlessness. [p for trend <0.0001]. CONCLUSIONS: Bronchodilator responsiveness in FEV1 or FVC are associated with different respiratory symptoms in the community. Both flow and volume bronchodilator responses are useful parameters which together can be predictive of both wheezing and breathlessness in the general population.

    An elderly woman diagnosed with multiple myeloma (MM) in 2007 had improved with chemotherapy. She had severe kyphosis and a diaphragmatic hernia (DH), but no respiratory symptoms. In 2011, because of thoracic deformity and emaciation, we advised her to continue the previously prescribed domiciliary noninvasive positive pressure ventilation (NPPV) therapy for chronic type II respiratory failure. However, she refused to continue NPPV. She was later admitted for deterioration in respiratory status and carbon dioxide (CO2) narcosis. We believed her low adherence to domiciliary NPPV caused CO2 narcosis; hence, we advised her to continue domiciliary NPPV and she complied. In May 2012, the now 79-year-old patient was admitted for acute exacerbation of chronic respiratory failure and CO2 narcosis. Chest imaging suggested that DH had caused a deterioration of her status. She underwent laparoscopic diaphragmatic hernia repair. Operative findings revealed a retrosternal hernia sac, and she was diagnosed as having a Morgagni hernia (MH). Her respiratory status subsequently improved. We hypothesize that NPPV increased intra-abdominal pressure, thereby worsening the MH and exacerbating respiratory failure. We believe that clinicians should be cautious when prescribing NPPV for MH patients.

    Full Text Available We studied the role of base excess (BE as marker of chronic hypercapnia and survival in patients with chronic obstructive pulmonary disease (COPD and chronic hypercapnic respiratory failure (CHRF. Moreover, it was investigated whether the effects of non-invasive positive pressure ventilation (NPPV on CHRF were reflected in BE and survival. In 240 (160 without exacerbation patients with COPD (mean±SD FEV1 30.7±9.7 %pred; PaCO2 56.9±9.9 mmHg body-mass index (BMI, lung function, respiratory muscle function, blood gases and 6-minute walking distance (6-MWD were assessed prior to initiation of NPPV. In addition, the changes of risk factors 6.3±2.9 months after initiation of NPPV were evaluated. Overall mortality during the follow-up time (26.0±24.5 months was 34.6%. Deaths resulted predominantly from respiratory causes (65.1%; among those, respiratory failure was most frequent (85.2%. Univariate analysis revealed BMI, FEV1, maximal inspiratory pressure (PImax, inspiratory load (P0.1, haemoglobin, 6-MWD, hyperinflation (IC/TLC, RV/TLC, blood gases and BE to be associated (p<0.05 each with prognosis. In multivariate analyses, however, only BMI, RV/TLC and BE turned out to be independent cross-sectional predictors (p<0.05. Kaplan-Meier analyses showed that BE had predictive value particularly in patients with BMI25 kg·m–2, RV/TLC70 % and PaCO257 mmHg. Furthermore, changes of BMI, RV/TLC and BE (p<0.01 were associated with improved prognosis in severe hypercapnic COPD. In patients with COPD and CHRF, BE was a prognostic marker for mortality, that was independent from other factors, particularly PaCO2. In addition, reversal of CHRF was reflected in BE and appeared to have an impact on prognosis.

    Myotonic dystrophy (DM1) is a multisystemic disease caused by an expansion of CTG repeats in the region of DMPK, the gene encoding DM protein kinase. The severity of muscle disability in DM1 correlates with the size of CTG expansion. As respiratory failure is one of the main causes of death in DM1, we investigated the correlation between respiratory impairment and size of the (CTG)n repeat in DM1 animal models. Using pressure plethysmography the respiratory function was assessed in control an...

    Myotonic dystrophy (DM1) is a multisystemic disease caused by an expansion of CTG repeats in the region of DMPK, the gene encoding DM protein kinase. The severity of muscle disability in DM1 correlates with the size of CTG expansion. As respiratory failure is one of the main causes of death in DM1, we investigated the correlation between respiratory impairment and size of the (CTG)n repeat in DM1 animal models. Using pressure plethysmography the respiratory function was assessed in control and transgenic mice carrying either 600 (DM600) or >1300 CTG repeats (DMSXL). The statistical analysis of respiratory parameters revealed that both DM1 transgenic mice sub-lines show respiratory impairment compared to control mice. In addition, there is no significant difference in breathing functions between the DM600 and DMSXL mice. In conclusion, these results indicate that respiratory impairment is present in both transgenic mice sub-lines, but the severity of respiratory failure is not related to the size of the (CTG)n expansion.

    Continuous positive airway pressure (CPAP) and noninvasive ventilation (NIV) are frequently used inhospital for treating respiratory failure, especially in treatment of acute cardiogenic pulmonary edema and exacerbation of chronic obstructive pulmonary disease. Early initiation of treatment...... is important for success and introduction already in the prehospital setting may be beneficial. Our goal was to assess the evidence for an effect of prehospital CPAP or NIV as a supplement to standard medical treatment alone on the following outcome measures; mortality, hospital length of stay, intensive care...... examine prehospital CPAP. Of these, only one small, randomized controlled trial shows a reduced mortality rate and a reduced intubation rate with supplemental CPAP. The other three studies have neutral findings, but in two of these a trend toward lower intubation rate is found. The effect of supplemental...

    We report the case of a 47-year old Caucasian man with a history of depression and high alcohol intake who presented with a one-month history of weight loss, dry cough and abdominal pain. He had no smoking history of note. The patient was treated for a suspected chest infection, however developed respiratory failure and was intubated. A CT showed multiple pulmonary nodules, left pleural thickening extending to the mediastinum and bilateral pleural effusions-larger on the left, suggestive of disseminated malignancy. A broncho-alveolar lavage surprisingly contained numerous acid-fast bacilli and no malignant cells. Treatment for tuberculosis was initiated and the patient recovered gradually. After several weeks, a pyrazinamide-resistant organism was cultured and subsequently identified to be Mycobacterium Bovis. We discuss this unexpected finding and review the literature on Bovine Tuberculosis in humans.

    2009-05-01

    Full Text Available Abstract Introduction The occurrence of an intravascular lymphoma with severe pulmonary involvement mimicking pulmonary embolism is described. Case presentation A 38-year-old man was referred to our intensive care unit with acute respiratory failure and long lasting fever. Appropriate investigations failed to demonstrate any bacterial, viral, parasitic or mycobacterial infection. A chest computed tomography scan ruled out any proximal or sub-segmental pulmonary embolism but the ventilation/perfusion lung scan concluded that there was a high probability of pulmonary embolism. The cutaneous biopsy pathology diagnosed intravascular lymphoma. Conclusion Intravascular lymphoma is a rare disease characterized by exclusive or predominant growth of neoplastic cells within the lumina of small blood vessels. Lung involvement seems to be common, but predominant lung presentation of this disease is rare. In our patient, urgent chemotherapy, along with adequate supportive care allowed complete recovery.

    Full Text Available Macrocystic lymphatic malformations (cystic hygromas are a common cause of cystic neck lesions. These lesions are often diagnosed prenatally in children. In cases without airway compromise, these children are discharged from the hospital for elective treatment. Surgical excision is one treatment modality while sclerotherapy has recently shown adequate results as well. While infection is a relatively common problem for lymphatic malformations, the majority can be treated with antibiotics alone. We present a case in which septic shock and respiratory failure resulted from primary infection of a macrocystic lymphatic malformation in a term infant discharged with a lymphatic malformation of the neck. Urgent surgical drainage failed, and complete excision was ultimately required for source control due to numerous small multiloculated small cysts inaccessible via incision and drainage.

    Death from traumatic shock has been associated with loss of blood externally or internally. However, many patients die after trauma, even though blood volume restoration is adequate. Death is often due to pulmonary failure (adult respiratory distress syndrome [ARDS]). Death and ARDS have been associated with disseminated intravascular coagulation (DIC) and microclots in the lungs. Dissolution of the microclots after trauma can be achieved by activation of endogenous plasmin. Nine pigs were anesthetized for 48 h. Trauma was administered by 60 standard blows to each thigh resulting in a bruise of muscle but no skin, bone, or major vessel injury. Nutrition and respiration were maintained at normal levels. All nine pigs died with severe lung pathology and low PaO2. Ten other traumatized pigs were treated with a plasminogen activator iv 4 h after trauma. Five of these were treated with tissue plasminogen activator (tPA) and five with urokinase. All treated pigs survived 48 h and maintained a normal PaO2. Autopsy showed minimal lung pathology.

  5. Noninvasive ventilation for acute respiratory failure: state of the art (I part

    2013-04-01

    Full Text Available Background: In the last years Non-Invasive Ventilation (NIV has been playing an important role in the treatment of Acute Respiratory Failure (ARF. A lot of trials have shown improvements in clinical features (respiratory rate, neurological score, pH and arterial blood gases. Methods: In particular clinical conditions, such as Acute Cardiogenic Pulmonary Edema (ACPE and acute exacerbation of Chronic Obstructive Pulmonary Disease (COPD, systematic reviews and meta-analysis show a reduction in the need for intubation and in-hospital mortality compared to standard medical treatment. In other clinical conditions, such as acute asthma, Acute Lung Injury (ALI/Acute Respiratory Distress Syndrome (ARDS and severe pneumonia, NIV does not show significant improvements in term of avoided intubations or mortality rate. Although the first important data on NIV comes from studies performed in Intensive Care Units (ICUs, subsequently these methodologies of ventilation have been used with increasing frequency in Emergency Departments (ED and medical wards. Results: Studies developed in ICU sometimes report slightly worse outcomes compared to studies performed in general wards due to the need to treat more severe patients in ICU. Aetiology remains one of the most important factor determining prognosis: different pathological mechanisms substain different clinical conditions and not in all cases the application of positive pressures to the airways is useful. NIV for ARF due to COPD and ACPE is feasible, safe and effective also in a general medical ward if selection of patients, staff training and monitoring are appropriate: its early application improves clinical parameters, arterial blood gases, prevents endotracheal intubation, decreases mortality and hospitalisation. This should encourage the diffusion of NIV in this specific setting.

    2011-10-01

    Full Text Available Abstract Introduction Media sensationalism on the H1N1 outbreak may have influenced decisional processes and clinical diagnosis. Case Presentation We report two cases of patients who presented in 2009 with coexisting H1N1 virus and Legionella infections: a 69-year-old Caucasian man and a 71-year-old Caucasian woman. In our cases all the signs and symptoms, including vomiting, progressive respiratory disease leading to respiratory failure, refractory hypoxemia, leukopenia, lymphopenia, thrombocytopenia, and elevated levels of creatine kinase and hepatic aminotransferases, were consistent with critical illness due to 2009 H1N1 virus infection. Other infectious disorders may mimic H1N1 viral infection especially Legionnaires' disease. Because the swine flu H1N1 pandemic occurred in Autumn in Italy, Legionnaires disease was to be highly suspected since the peak incidence usually occurs in early fall. We do think that our immediate suspicion of Legionella infection based on clinical history and X-ray abnormalities was fundamental for a successful resolution. Conclusion Our two case reports suggest that patients with H1N1 should be screened for Legionella, which is not currently common practice. This is particularly important since the signs and symptoms of both infections are similar.

Outcome data in these patients are scarce.Clinical and radiological features were collected in 83 patients with ILD-associated acute respiratory failure (ARF. Determinants of hospital mortality and response to corticosteroid therapy were identified by logistic regression.Hospital and 1-year mortality rates were 41% and 54% respectively. Pulmonary hypertension, computed tomography (CT fibrosis and acute kidney injury were independently associated with mortality (odds ratio (OR 4.55; 95% confidence interval (95%CI (1.20-17.33; OR, 7.68; (1.78-33.22 and OR 10.60; (2.25-49.97 respectively. Response to steroids was higher in patients with shorter time from hospital admission to corticosteroid therapy. Patients with fibrosis on CT had lower response to steroids (OR, 0.03; (0.005-0.21. In mechanically ventilated patients, overdistension induced by high PEEP settings was associated with CT fibrosis and hospital mortality.Mortality is high in ILD-associated ARF. CT and echocardiography are valuable prognostic tools. Prompt corticosteroid therapy may improve survival.

    Acute and chronic respiratory failure is one of the major and potentially life-threatening features in individuals with myotonic dystrophy type 1 (DM1). Despite several clinical demonstrations showing respiratory problems in DM1 patients, the mechanisms are still not completely understood. This study was designed to investigate whether the DMSXL transgenic mouse model for DM1 exhibits respiratory disorders and, if so, to identify the pathological changes underlying these respiratory problems. Using pressure plethysmography, we assessed the breathing function in control mice and DMSXL mice generated after large expansions of the CTG repeat in successive generations of DM1 transgenic mice. Statistical analysis of breathing function measurements revealed a significant decrease in the most relevant respiratory parameters in DMSXL mice, indicating impaired respiratory function. Histological and morphometric analysis showed pathological changes in diaphragmatic muscle of DMSXL mice, characterized by an increase in the percentage of type I muscle fibers, the presence of central nuclei, partial denervation of end-plates (EPs) and a significant reduction in their size, shape complexity and density of acetylcholine receptors, all of which reflect a possible breakdown in communication between the diaphragmatic muscles fibers and the nerve terminals. Diaphragm muscle abnormalities were accompanied by an accumulation of mutant DMPK RNA foci in muscle fiber nuclei. Moreover, in DMSXL mice, the unmyelinated phrenic afferents are significantly lower. Also in these mice, significant neuronopathy was not detected in either cervical phrenic motor neurons or brainstem respiratory neurons. Because EPs are involved in the transmission of action potentials and the unmyelinated phrenic afferents exert a modulating influence on the respiratory drive, the pathological alterations affecting these structures might underlie the respiratory impairment detected in DMSXL mice.

    The purpose of this study was to explore the care processes experienced by community-dwelling adults dying from advanced heart failure, their family caregivers, and their health-care providers. A descriptive qualitative design was used to guide data collection, analysis, and interpretation. The sample comprised 8 patients, 10 informal caregivers, 11 nurses, 3 physicians, and 3 pharmacists. Data analysis revealed that palliative care was influenced by unique contextual factors (i.e., cancer model of palliative care, limited access to resources, prognostication challenges). Patients described choosing interventions and living with fatigue, pain, shortness of breath, and functional decline. Family caregivers described surviving caregiver burden and drawing on their faith. Health professionals described their role as trying to coordinate care, building expertise, managing medications, and optimizing interprofessional collaboration. Participants strove towards 3 outcomes: effective symptom management, satisfaction with care, and a peaceful death.

    Our purpose was to evaluate the association of new benzodiazepine use relative to non-use with adverse clinical respiratory outcomes among older adults with chronic obstructive pulmonary disease (COPD). This was a retrospective population-based cohort study of Ontario, Canada, residents between 2003 and 2010. A validated algorithm was applied to health administrative data to identify adults aged 66 years and older with COPD. Relative risks (RRs) of several clinically important respiratory outcomes were examined within 30 days of incident benzodiazepine use compared with non-use, applying propensity score matching. New benzodiazepine users were at significantly higher risk for outpatient respiratory exacerbations (RR 1.45, 95% CI 1.36-1.54) and emergency room visits for COPD or pneumonia (RR 1.92, 95% CI 1.69-2.18) compared to non-users. Risk of hospitalisation for COPD or pneumonia was also increased in benzodiazepine users, but was nonsignificant (RR 1.09, 95% CI 1.00-1.20). There were no significant differences in intensive care unit admissions between the two groups and all-cause mortality was slightly lower among new versus non-users. Benzodiazepines were associated with increased risk for several serious adverse respiratory outcomes among older adults with COPD. The findings suggest that decisions to use benzodiazepines in older patients with COPD need to consider potential adverse respiratory outcomes.

    Abrupt destruction of >70% of the pre-Bötzinger complex (preBötzC) in awake goats results in terminal apnea (Wenninger et al. 2004b). Herein we report data on awake and sleeping goats in which the preBötzC was incrementally destroyed by injection of ibotenic acid (IBO) in increasing volumes at weekly intervals. All injections resulted in an acute tachypnea and dysrhythmia featuring apneas and increased variation in breathing. In studies at night, 10-15 hours after the injections, apneas were nearly all central and occurred during the awake state and variation in breathing was greater while awake than during NREM sleep. However, one week after the final IBO injection, the breathing pattern, breath-to-breath variation, and arterial blood gases were unchanged from baseline, indicating recovery. Histology revealed more than 90% destruction of the preBötzC region, and greater than 80% destruction of the surrounding area. We conclude: (1) the dysrhythmic effects on breathing acutely after the injection are state-dependent, and (2) after incremental, near-complete destruction of the preBötzC region, time-dependent plasticity within the respiratory network provides a normal respiratory rhythm that sustains normal arterial blood gases.

    Full Text Available Objectives: To correlate the degree of encephalopathy, baseline values of PaCO2 and pH, and their early response to NIV with eventual in-hospital outcome in patients of severe acute-on-chronic hypercapnic respiratory failure in COPD. Design: Retrospective review. Setting: Intensive care unit. Material and methods: 24 episodes of acute exacerbation of COPD in 17 patients (10 females, 7 males with a mean age of 59.5 years (range 48 - 82 where NIV was initiated. Data collected: encephalopathy score at baseline and at 24 hours, respiratory rate, breathing pattern, serial arterial blood gases, duration of NIV support per day and hospital days. Results: All patients had severe hypercapnia (mean peak PaCO2 89.0 mm Hg ± 21; range 66-143, respiratory acidosis (mean nadir pH 7.24 ± 0.058, range 7.14 - 7.33 and tachypnoea (mean respiratory rate 29.5 ± 4.69/mt; range 24 - 40. In 17 episodes, altered mental state was present (encephalopathy score 1.92 ± 1.32, median 2.5. Clinically stable condition occurred over several days (mean 13± 9.6 days; range 5 - 40. Intubation was avoided in 22 out of 24 episodes (91.6% despite significant initial worsening of PaCO2 and pH. Two patients died. The mean time on NIV was16.5 hours/day (range 4 - 22. Conclusions: In selected patients of COPD with acute hypercapnic failure on NIV worsening PaCO2 and pH in the initial hours may not predict failure provided the level of consciousness and respiratory distress improve.

    2014-06-01

    Questions surrounding physiological interdependence in romantic relationships are gaining increased attention in the research literature. One specific form of interdependence, coregulation, can be defined as the bidirectional linkage of oscillating signals within optimal bounds. Conceptual and theoretical work suggests that physiological coregulation should be instantiated in romantic couples. Although these ideas are appealing, the central tenets of most coregulatory models await empirical evaluation. In the current study, we evaluate the covariation of respiratory sinus arrhythmia (RSA) in 32 romantic couples during a series of laboratory tasks using a cross-lagged panel model. During the tasks, men's and women's RSA were associated with their partners' previous RSA responses, and this pattern was stronger for those couples with higher relationship satisfaction. The findings are discussed in terms of their implications for attachment theory, as well as the association between relationships and health.

    The data show respiratory variables in 108 critically ill patients with acute respiratory failure placed on proportional assist ventilation with load adjustable gain factors (PAV+) after at least 36 h on passive mechanical ventilation. PAV+ was continued for 48 h until the patients met pre-defined criteria either for switching to controlled modes or for breathing without ventilator assistance. Data during passive mechanical ventilation and during PAV+ are reported. Data are acquired from the whole population, as well as from patients with and without acute respiratory distress syndrome. The reported variables are tidal volume, driving pressure (ΔP, the difference between static end-inspiratory plateau pressure and positive end-expiratory airway pressure), respiratory system compliance and resistance, and arterial blood gasses.

    We studied the porcine pulmonary response to endotoxemia before and after administration of nonsteroidal antiinflammatory drugs (NSAID, i.e., indomethacin or flunixin meglumine) or dexamethasone (DEX). Escherichia coli endotoxin was infused intravenously into anesthetized 10- to 12-wk old pigs for 4.5 h. In endotoxemic pigs, the phase 1 (i.e., 0-2 h) increases in pulmonary arterial pressure, pulmonary vascular resistance (PVR), and alveolar-arterial O2 gradient and the decreases in cardiac index (CI) and lung dynamic compliance (Cdyn) were blocked by NSAID. Thus phase 1 changes were cyclooxygenase dependent. Furthermore, these effects were blocked or greatly attenuated by DEX. During phase 2 of endotoxemia (i.e., 2-4.5 h), the increased PVR and decreased CI and Cdyn were not blocked by NSAID but were attenuated by DEX, suggesting the presence of cyclooxygenase-independent metabolites. Both NSAID and DEX blocked the endotoxin-induced increases in lung water, bronchoalveolar lavage (BAL) neutrophil, and BAL albumin content. The fall in plasma proteins persisted in NSAID but not DEX-treated pigs. We conclude that endotoxemia in the pig causes severe acute respiratory failure largely mediated by cyclooxygenase and possibly lipoxygenase products of arachidonic acid metabolism.

  6. Predicting postoperative acute respiratory failure in critical care using nursing notes and physiological signals.

    2014-01-01

    Postoperative Acute Respiratory Failure (ARF) is a serious complication in critical care affecting patient morbidity and mortality. In this paper we investigate a novel approach to predicting ARF in critically ill patients. We study the use of two disparate sources of information – semi-structured text contained in nursing notes and investigative reports that are regularly recorded and the respiration rate, a physiological signal that is continuously monitored during a patient's ICU stay. Unlike previous works that retrospectively analyze complications, we exclude discharge summaries from our analysis envisaging a real time system that predicts ARF during the ICU stay. Our experiments, on more than 800 patient records from the MIMIC II database, demonstrate that text sources within the ICU contain strong signals for distinguishing between patients who are at risk for ARF from those who are not at risk. These results suggest that large scale systems using both structured and unstructured data recorded in critical care can be effectively used to predict complications, which in turn can lead to preemptive care with potentially improved outcomes, mortality rates and decreased length of stay and cost.

    Full Text Available BACKGROUND: Congestive heart failure is associated with decline in quality of life and, possibly, cognitive functions such as memory and attention. AIMS: The present study was designed to investigate the presence of cognitive impairment amongst patients with congestive heart failure (CHF. We hypothesised that CHF patients would have lower scores than elderly controls on general measures of cognitive functioning. METHODS AND RESULTS: We examined a sample of 50 consecutive patients admitted to hospital with CHF functional class III/IV and a convenience sample of 30 older adults assessed at the outpatient service of geriatric medicine of a teaching hospital in São Paulo, Brazil. All subjects were interviewed with the Cambridge Examination for Mental Disorders of the Elderly (CAMDEX, as well as the neuropsychological battery of the CAMDEX (CAMCOG, Mini-Mental State Examination (MMSE, Trail Making A and B, Digit Span, Digit Symbol, and Letter Cancellation Test. All CHF patients had left ventricular ejection fraction (EF below 45% and all controls above 65%. The cognitive performance of CHF patients was significantly worse than controls for all cognitive assessments. Twenty-seven of 50 CHF patients had a MMSE total score lower than 24, compared with only 10/30 controls (p=0.073. Similarly, 36/49 and 9/30 CHF subjects and controls respectively had CAMCOG scores below 80 (p<0.001. Cognitive scores were significantly associated with EF, which was the most robust predictor of cognitive impairment according to the CAMCOG in a logistic regression model. CONCLUSION: Our results indicate that CHF is associated with significant levels of cognitive impairment and show that mental performance is, at least partly, a consequence of EF. Physicians should be prepared to assess the mental state of patients, as poor cognitive functioning may interfere with treatment compliance and management plan.

    Full Text Available Abstract Background Respiratory symptoms are common in the general population, and their presence is related to Health-related quality of life (HRQoL. The objective was to describe the association of respiratory symptoms with HRQoL in subjects with and without asthma or COPD and to investigate the role of atopy, bronchial hyperresponsiveness (BHR, and lung function in HRQoL. Methods The European Community Respiratory Health Survey (ECRHS I and II provided data on HRQoL, lung function, respiratory symptoms, asthma, atopy, and BHR from 6009 subjects. Generic HRQoL was assessed through the physical component summary (PCS score and the mental component summary (MCS score of the SF-36. Factor analyses and linear regressions adjusted for age, gender, smoking, occupation, BMI, comorbidity, and study centre were conducted. Results Having breathlessness at rest in ECRHS II was associated with mean score (95% CI impairment in PCS of -8.05 (-11.18, -4.93. Impairment in MCS score in subjects waking up with chest tightness was -4.02 (-5.51, -2.52. The magnitude of HRQoL impairment associated with respiratory symptoms was similar for subjects with and without asthma/COPD. Adjustments for atopy, BHR, and lung function did not explain the association of respiratory symptoms and HRQoL in subjects without asthma and/or COPD. Conclusion Subjects with respiratory symptoms had poorer HRQoL; including subjects without a diagnosis of asthma or COPD. These findings suggest that respiratory symptoms in the absence of a medical diagnosis of asthma or COPD are by no means trivial, and that clarifying the nature and natural history of respiratory symptoms is a relevant challenge. Several community studies have estimated the prevalence of common respiratory symptoms like cough, dyspnoea, and wheeze in adults 123. Although the prevalence varies to a large degree between studies and geographical areas, respiratory symptoms are quite common. The prevalences of respiratory

    Directory of Open Access Journals (Sweden)

    Claudio Terzano

    Full Text Available BACKGROUND: Hypercapnic Chronic Obstructive Pulmonary Disease (COPD exacerbation in patients with comorbidities and multidrug therapy is complicated by mixed acid-base, hydro-electrolyte and lactate disorders. Aim of this study was to determine the relationships of these disorders with the requirement for and duration of noninvasive ventilation (NIV when treating hypercapnic respiratory failure. METHODS: Sixty-seven consecutive patients who were hospitalized for hypercapnic COPD exacerbation had their clinical condition, respiratory function, blood chemistry, arterial blood gases, blood lactate and volemic state assessed. Heart and respiratory rates, pH, PaO(2 and PaCO(2 and blood lactate were checked at the 1st, 2nd, 6th and 24th hours after starting NIV. RESULTS: Nine patients were transferred to the intensive care unit. NIV was performed in 11/17 (64.7% mixed respiratory acidosis-metabolic alkalosis, 10/36 (27.8% respiratory acidosis and 3/5 (60% mixed respiratory-metabolic acidosis patients (p = 0.026, with durations of 45.1 ± 9.8, 36.2 ± 8.9 and 53.3 ± 4.1 hours, respectively (p = 0.016. The duration of ventilation was associated with higher blood lactate (p<0.001, lower pH (p = 0.016, lower serum sodium (p = 0.014 and lower chloride (p = 0.038. Hyponatremia without hypervolemic hypochloremia occurred in 11 respiratory acidosis patients. Hypovolemic hyponatremia with hypochloremia and hypokalemia occurred in 10 mixed respiratory acidosis-metabolic alkalosis patients, and euvolemic hypochloremia occurred in the other 7 patients with this mixed acid-base disorder. CONCLUSIONS: Mixed acid-base and lactate disorders during hypercapnic COPD exacerbations predict the need for and longer duration of NIV. The combination of mixed acid-base disorders and hydro-electrolyte disturbances should be further investigated.

    Rapidly progressive acute respiratory failure attributed to 2009 H1N1 influenza A infection has been reported worldwide-3. Refractory hypoxaemia despite conventional mechanical ventilation and lung protective strategies has resulted in the use a combination of rescue therapies, such as conservative fluid management, prone positioning, inhaled nitric oxide, high frequency oscillatory ventilation and extracorporeal membrane oxygenation (ECMO)4. ECMO allows for pulmonary or cardiopulmonary support as an adjunct to respiratory and cardiac failure, minimising ventilator-associated lung injury (VALI). This permits treatment of the underlying disease process, while concurrently allowing for recovery of the acute lung injury. This case documents a previously healthy twenty-two year old Asian male patient with confirmed pandemic (H 1N1) 2009 influenza A who was successfully managed with ECMO in the setting of severe refractory hypoxaemia and progressive hypercapnia.

    Acute respiratory failure resistant to conventional pulmonary therapy often requires intensive medical care. In rare cases, ventilator therapy proves insufficient, and only the option of employing veno-venous extracorporeal membrane oxygenation (ECMO V-V) remains. The present article describes the case of a 23-year-old patient who experienced severe acute respiratory distress syndrome with associated multiple organ failure. The patient was admitted to the pulmonary ward of the Alfred Sokołowski Regional Pulmonary Hospital in Szczecin-Zdunowo with suspected pneumonia of unknown etiology. After the initial 5 days of diagnostics at the pulmonary ward, the patient required a further 97 days of hospital treatment and spent 63 days at the Intensive Care Unit. There, he underwent ECMO V-V therapy lasting 22 days, which resulted in the improvement of his arterial blood gas parameters and clinical condition. PMID:26336483

    Full Text Available Background: It is estimated that 5.7 million Americans are living with heart failure (HF today. Despite the fact that HF is one of the most common reasons people aged 65 years and older are admitted into the hospital, few studies describe the self-care in this older adult population. Purpose: The purpose of the study was to review the current literature on self-care in this population to better understand the influence of selected factors on self-care and health outcomes. Methods: A literature search was completed and resulted in including 28 studies. Results: Multiple factors have been reported as barriers to self-care including depression and presence of peripheral arterial disease. Factors having a positive effect on self-care are male gender, number of cardiologist referrals, and self-efficacy. There were few studies that described the association between cognitive functioning and self-care. There is a lack of strong evidence to support the association between self-care and health outcomes such as readmission rate, but recent studies suggest that a 30-day readmission is not a valid predictor of health outcomes. Implications: The assessment of the psychological factors and health care resource utilization patterns that may influence self-care is recommended. More research that addresses the role of cognitive factors in influencing self-care is needed.

    Full Text Available BACKGROUND : Non - invasive ventilation (NIV is the delivery of positive pressure ventilation through an interface to upper airways without using the invasive airway. Use of NIV is becoming common with the increasing recognition of its benefits. OBJECTIVES: This study was done to evaluate the feasibility and outcome of NIV (BiPAP in Type II Respiratory Failu re in Department of Pulmonary Medicine, Kurnool Medical College. Materials and Methods: An observational study conducted over a period of 18 months in Department of pulmonary medicine, Kurnool Medical C ollege in 40 patients who were treated by NIV (BiPaP. Patients were stratified on basis of set of exclusion and inclusion criteria. NIV was given in accordance with the arterial blood gas (ABG parameters defining Type II respiratory failure. RESULTS: In the present study NIPPV was successful in 34(85% and failed in 6(15% patients . The most common indication of NIV in our hospital was acute exacerbation of chronic obstructive pulmonary disease (AE - COPD 90% and 88% of AE - COPD patients were improved by NIV. Application of NIV resulted in significant improvem ent of pH and blood gases in COPD patients. Kyphoscoliosis, Obstructive Sleep Apnea (OSA patients with Type II Respirato r y failure also showed significant improvement in partial pressure of oxygen and carbon dioxide. CONCLUSION: This study demonstrates and encourages the use of NIV as the first - line ventilator treatment in AE - COPD patients with Type II respiratory failure. It also supports NIV usage in other causes of type II Respiratory failure as a promising step toward prevention of mechanical ventila tion.

    Full Text Available Appropriate intervention is critical in reducing deaths among under-five, severe acutely malnourished (SAM children with danger signs of severe pneumonia; however, there is paucity of data on outcome of World Health Organisation (WHO recommended interventions of SAM children with severe pneumonia. We sought to evaluate outcome of the interventions in such children.We prospectively enrolled SAM children aged 0-59 months, admitted to the Intensive Care Unit (ICU or Acute Respiratory Infection (ARI ward of the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b, between April 2011 and June 2012 with cough or respiratory difficulty and radiological pneumonia. All the enrolled children were treated with ampicillin and gentamicin, and micronutrients as recommended by the WHO. Comparison was made among pneumonic children with (n = 111 and without WHO defined danger signs of severe pneumonia (n = 296. The outcomes of interest were treatment failure (if a child required changing of antibiotics and deaths during hospitalization. Further comparison was also made among those who developed treatment failure and who did not and among the survivors and deaths.SAM children with danger signs of severe pneumonia more often experienced treatment failure (58% vs. 20%; p<0.001 and fatal outcome (21% vs. 4%; p<0.001 compared to those without danger signs. Only 6/111 (5.4% SAM children with danger signs of severe pneumonia and 12/296 (4.0% without danger signs had bacterial isolates from blood. In log-linear binomial regression analysis, after adjusting for potential confounders, danger signs of severe pneumonia, dehydration, hypocalcaemia, and bacteraemia were independently associated both with treatment failure and deaths in SAM children presenting with cough or respiratory difficulty and radiological pneumonia (p<0.01.The result suggests that SAM children with cough or respiratory difficulty and radiologic pneumonia who

  20. Increased Plasma Levels of Heparin-Binding Protein on Admission to Intensive Care Are Associated with Respiratory and Circulatory Failure.

    Jonas Tydén

    Full Text Available Heparin-binding protein (HBP is released by granulocytes and has been shown to increase vascular permeability in experimental investigations. Increased vascular permeability in the lungs can lead to fluid accumulation in alveoli and respiratory failure. A generalized increase in vascular permeability leads to loss of circulating blood volume and circulatory failure. We hypothesized that plasma concentrations of HBP on admission to the intensive care unit (ICU would be associated with decreased oxygenation or circulatory failure.This is a prospective, observational study in a mixed 8-bed ICU. We investigated concentrations of HBP in plasma at admission to the ICU from 278 patients. Simplified acute physiology score (SAPS 3 was recorded on admission. Sequential organ failure assessment (SOFA scores were recorded daily for three days.Median SAPS 3 was 58.8 (48-70 and 30-day mortality 64/278 (23%. There was an association between high plasma concentrations of HBP on admission with decreased oxygenation (p<0.001 as well as with circulatory failure (p<0.001, after 48-72 hours in the ICU. There was an association between concentrations of HBP on admission and 30-day mortality (p = 0.002. ROC curves showed areas under the curve of 0,62 for decreased oxygenation, 0,65 for circulatory failure and 0,64 for mortality.A high concentration of HBP in plasma on admission to the ICU is associated with respiratory and circulatory failure later during the ICU care period. It is also associated with increased 30-day mortality. Despite being an interesting biomarker for the composite ICU population it's predictive value at the individual patient level is low.

    We evaluated risk of adverse respiratory outcomes associated with incident opioid use among older adults with chronic obstructive pulmonary diseases (COPD).This was a retrospective population-based cohort study using a validated algorithm applied to health administrative data to identify adults aged 66 years and older with COPD. Inverse probability of treatment weighting using the propensity score was used to estimate hazard ratios comparing adverse respiratory outcomes within 30 days of incident opioid use compared to controls.Incident opioid use was associated with significantly increased emergency room visits for COPD or pneumonia (HR 1.14, 95% CI 1.00-1.29; p=0.04), COPD or pneumonia-related mortality (HR 2.16, 95% CI 1.61-2.88; p<0.0001) and all-cause mortality (HR 1.76, 95% CI 1.57-1.98; p<0.0001), but significantly decreased outpatient exacerbations (HR 0.88, 95% CI 0.83-0.94; p=0.0002). Use of more potent opioid-only agents was associated with significantly increased outpatient exacerbations, emergency room visits and hospitalisations for COPD or pneumonia, and COPD or pneumonia-related and all-cause mortality.Incident opioid use, and in particular use of the generally more potent opioid-only agents, was associated with increased risk for adverse respiratory outcomes, including respiratory-related mortality, among older adults with COPD. Potential adverse respiratory outcomes should be considered when prescribing new opioids in this population.

    Total liquid ventilation (TLV) has the potential to provide respiratory support superior to conventional mechanical ventilation (CMV) in the acute respiratory distress syndrome (ARDS). However, laboratory studies are limited to trials in small animals for no longer than 4 hours. The objective of this study was to compare TLV and CMV in a large animal model of ARDS for 24 hours. Ten sheep weighing 53 ± 4 (SD) kg were anesthetized and ventilated with 100% oxygen. Oleic acid was injected into the pulmonary circulation until PaO2:FiO2 ≤ 60 mm Hg, followed by transition to a protective CMV protocol (n = 5) or TLV (n = 5) for 24 hours. Pathophysiology was recorded, and the lungs were harvested for histological analysis. Animals treated with CMV became progressively hypoxic and hypercarbic despite maximum ventilatory support. Sheep treated with TLV maintained normal blood gases with statistically greater PO2 (p < 10(-9)) and lower PCO2 (p < 10(-3)) than the CMV group. Survival at 24 hours in the TLV and CMV groups were 100% and 40%, respectively (p < 0.05). Thus, TLV provided gas exchange superior to CMV in this laboratory model of severe ARDS.

    The treatment of choice for patients with respiratory failure of neuromuscular origin, especially in patients with hypercapnic respiratory acidosis, is noninvasive ventilation (NIV). Endotracheal intubation and invasive ventilation are indicated for patients with severe respiratory compromise or failure of NIV. In recent years, high-flow oxygen therapy and active humidification devices have been introduced, and emerging evidence suggests that high-flow oxygen may be effective in various clinical settings, such as acute respiratory failure, after cardiac surgery, during sedation and analgesia, in acute heart failure, in hypoxemic respiratory distress, in do-not-intubate patients, in patients with chronic cough and copious secretions, pulmonary fibrosis, or cancer, in critical areas and the emergency department. We report on a patient with amyotrophic lateral sclerosis who arrived at the emergency department with acute hypercapnic respiratory failure. She did not tolerate NIV and refused intubation, but was treated successfully with heated, humidified oxygen via high-flow nasal cannula. Arterial blood analysis after an hour on high-flow nasal cannula showed improved pH, P(aCO2), and awareness. The respiratory acidosis was corrected, and she was discharged after 5 days of hospitalization. Her response to high-flow nasal cannula was similar to that expected with NIV. We discuss the mechanisms of action of heated, humidified high-flow oxygen therapy.

    Acute respiratory distress syndrome (ARDS) increases mortality in patients with multiorgan dysfunction syndrome (MODS). This study evaluates the feasibility of intrapleural steroid instillation (IPSI) in patients with ARDS and MODS unresponsive to conventional extracorporeal membrane oxygenation (ECMO). Ninety-two of 467 patients who underwent ECMO between 2005 and 2009 had ARDS, and 30 consecutive adult patients of these 92 patients with severe ARDS and MODS were retrospectively analyzed in this study. Nine of these 30 patients, who did not respond to therapy and whose condition deteriorated, were managed with IPSI. All patients met the inclusion criteria of hemodynamic instability with high catecholamine infusion requirement and 100% oxygen demand in ventilation and ECMO flow. On initial diagnosis of ARDS, no differences in prognostic scorings were observed in patients who underwent conventional treatment (n = 21) and those who underwent IPSI (n = 9). Blood oxygenation, tidal volume, changing in chest radiographic findings, and survival rates were analyzed. The primary outcome was survival until discharge from the hospital. Pulmonary radiographic appearance improved after 3 days of IPSI treatment (P = 0.008); the ratio of arterial partial pressure of oxygen to fraction of inspired oxygen also increased significantly after 5 days of IPSI treatment (P = 0.028). Moreover, the 28-day mortality rate (P = 0.017), 60-day mortality rate (P = 0.003), and survival rate (78% vs. 19%; P = 0.003) significantly improved in patients undergoing IPSI, which therefore appears to be an easily implemented and highly effective treatment for patients with severe ARDS in combination with MODS, particularly in patients who fail to respond to conventional treatment.

    Full Text Available Background and Objective. Environmental factors are an increasing concern for respiratory health in developing countries. The objective of this study was to investigate whether Nigerien people living in cultivated areas have more respiratory symptoms than those living in pastoral areas. Method. A cross-sectional study was conducted in 2013 in two populations during the rainy season when land is cultivated. Environmental factors including pesticide use and respiratory symptoms were collected in adults and children during face-to-face interviews. Multivariate analysis between exposures and symptoms was performed in children and in adults separately. Results. The study included 471 adults and 229 children. Overall, none of the households reported the use of pesticides for agricultural purposes. However, 87.2% reported the use of insecticides at home. Multivariate analysis showed that people living in agricultural areas compared to those in pastoral areas had an increased risk of respiratory symptoms in adults (wheezing, dyspnea, sudden shortness of breath, and cough without fever and in children (cough without fever. The use of insecticides showed no effect on respiratory symptoms after adjustment. Conclusion. This first epidemiological study on the environment and respiratory health conducted in Niger demonstrates a significant relationship between respiratory manifestations and the agricultural characteristics of the living area. However only the effect of insecticides in the home on respiratory health was observed.

    Full Text Available We report a case of nephropleural fistula causing empyema and respiratory failure in a 68-year-old gentleman with a long history of urological problems including recurrent nephrolithiasis and urinary tract infections. He was admitted with sepsis, a productive cough, pyuria, and reduced breath sounds over the left hemithorax. Radiological imaging revealed a fistulous connection between a left-sided perinephric abscess and the pleural space. He was commenced on broad spectrum intravenous antibiotics but developed progressive respiratory failure requiring intensive care admission. Urinary and pleural aspirates cultured facultative anaerobic pathogens with identical resistance patterns. Drainage of thoracic and perinephric collections was carried out, allowing him to be extubated after 24 hours and discharged home after 18 days on an extended course of oral antibiotics. Left nephrectomy is now planned after a period of convalescence. Empyema developing in patients with known urolithiasis should alert the treating physician to the possibility that a pathological communication has formed especially if typical urinary tract pathogens are cultured from respiratory sampling.

    Study objective: To investigate the clinical features and prognosis of patients with coal worker's pneumoconiosis (CWP) requiring invasive mechanical ventilation (MV) in the ICU for their first episode of acute respiratory failure (ARF), with special attention to the prognostic implication of radiographic progressive massive fibrosis (PMF). Design: Retrospective study. Setting: A 16-bed medical ICU at a community hospital. Patients and methods: We reviewed 53 patients with CWP and ARF requiring invasive MV in the ICU for the first time between August 1998 and March 2002. Results: Of the 53 patients with CWP, 28 patients (53%) with PMF had their first ARF at a younger age than those without PMF. Pneumonia (49%) was the most common cause of ARF. The mean APACHE (acute physiology and chronic health evaluation) II score was 26.0 {+-}9.9, and the mean ICU stay was 14.7 {+-}16.1 days. Twenty-one patients (40%) were weaned successfully in the ICU, with mean ventilator time of 17.0 {+-}25.1 days. The ICU and in-hospital mortality rates were 40% and 43%, respectively. The median survivals for all patients and the ICU survivors were 2.6 months and 14.3 months, respectively. Multivariate analysis showed the following risk (or protective) factors for the ICU mortality: Paco(2) {gt} 45 mm Hg at the time of intubation (adjusted odds ratio (OR), 0.04; 95% confidence interval (CI), 0.003 to 0.44), Pao(2)/fraction of inspired oxygen ratio {lt} 200 mm Hg at the time of intubation (OR, 8.78; 95% CI, 1.36 to 56.48), and APACHE II score greater than or equal to 25 (OR, 11.99; 95% CI, 1.49 to 96.78). PMF was not associated with the ICU mortality (OR, 1.18; 95% CI, 0.20 to 7.10). Conclusions: Radiographic PMF was not associated with the ICU mortality in patients with CWP and ARF receiving invasive MV in the ICU. Although a substantial proportion of them could be weaned from the ventilator and discharged from the hospital, their long-term prognosis was poor.

The aim of this study was to evaluate functioning of the respiratory system and to estimate the correlation between the function parameters of the respiratory system and the level of physical activity and body composition in the adult rural population. The study involved a group of 116 people from rural population aged 35–60 years, staying on 3-week rehabilitation camps. They were divided into two groups: men (29 and women (87. The somatic features: body height, body weight, Body Mass Index (BMI and body copmposition were analysed, on the status of smoking and declared level of physical activity (PA was checked. For the evaluation of the functional parameters of the respiratory system the pattern of flow volume curve was used. The following parameters were determined: vital capacity (VC, forced vital capacity (FVC, forced expiratory volume in one second (FEV1, peak expiratory flow (PEF, MEF50 (maximum expiratory flow at 50% of VC and Tiffenau index. Hand grip and maximum torque of the knee join flexor and extensor muscles was measured. As expected, men had significantly higher levels of respiratory parameters. In analyzing the status of smoking cigarettes, it can be stated that the majority of subjects are smokers. conclusions. The values of functional parameters of the respiratory system were suitable for the age they were within the norm and did not show lung ventilation disorder. Most subjects of the study declared low physical activity which may be due to manual work on the farm. Smoking cigarettes significantly lowered the value of such parameters as FEV1, PEF and MEF50 only in the male group but the values did not indicate ventilatory disorder. Parameters of the respiratory system show the highest correlations with the parameters of muscle strength. Significant correlations with body compositions parameters (FFM, water have been noticed too.

    Takotsubo cardiomyopathy which is characterised by a transient left ventricular wall motion abnormality was first described in 1990. The disease is still not well known, and as such it is suggested that an emotional trigger is mandatory in this disease. We present the case of a 51-year old female patient seven years after bilateral lung transplantation, who developed acute respiratory distress syndrome and subsequently suffered from atypical takotsubo cardiomyopathy with transient severe reduction of ejection fraction and haemodynamic instability needing acute intensive care treatment. Acute respiratory failure has emerged as an important physical trigger factor in takotsubo cardiomyopathy. Little is known about the association of hypoxia and takotsubo cardiomyopathy which can elicit a life-threatening condition requiring acute intensive care. Therefore, experimental studies are needed to investigate the role of hypoxia in takotsubo cardiomyopathy.

    A 24-year-old woman developed adult respiratory distress syndrome (ARDS) after near-drowning due to attempted suicide. Conventional mechanical ventilation together with prone positioning and inhaled nitric oxide could not provide sufficient oxygenation. Surface tension data (gamma min = 27 dyn/cm, stability index = 0.341) from a lavage sample supported the hypothesis that the surfactant function of this patient was drastically reduced due to a washout effect by aspiration of fresh water. Porcine surfactant (Curosurf, 50 mg/kg for each lung) was instilled via fibreoptic bronchoscope. The partial arterial carbon dioxide pressure (paCO2) and fraction of inspired oxygen (FiO2) ratio as well as shunt fraction (Qs/Qt) improved impressively. When respiratory situation deteriorated again, surfactant application was repeated. Altogether, six bolus instillations of surfactant (total dose 300 mg/kg = 18,000 mg) were administered until the respiratory situation had stabilized and oxygenation could be maintained by conventional mechanical ventilation. The radiological findings did not show substantial amelioration. The patient developed septic shock and died 12 days after admission. Surfactant application apparently led to a significant improvement of the respiratory function. However, the outcome could not be influenced positively. The high cost of surfactant therapy prevents the more widespread early administration in patients at risk.

    Injury to the myocardium disrupts geometric integrity and results in changes to intracardiac pressure, wall stress and tension, and the pattern of blood flow through the heart. Significant disruption to pump function results in heart failure which is defined in terms of symptoms: breathlessness and fatigue, signs of salt and water retention, and neurohormonal activation. This syndrome most commonly occurs in the context of injury due to ischaemic heart disease and dilated cardiomyopathy but because patients with congenital heart disease (CHD) are born with sometimes gross distortions of cardiac anatomy they too are subject to the forces that drive heart failure. This paper explores the available data relating to the clinical and neurohormonal manifestations of heart failure in patients with congenital heart disease and describes how, by additionally exploring events at a cellular level, we may be able to arrive at a definition of heart failure relevant to this population.

    Objective To estimate the feasibility and the efficacy of early extubation and sequential non-invasive mechanical ventilation (MV) in chronic obstructive pulmonary disease (COPD) with exacerbated hypercapnic respiratory failure.Methods Twenty-two intubated COPD patients with severe hypercapnic respiratory failure due to pulmonary infection (pneumonia or purulent bronchitis) were involved in the study. At the time of pulmonary infection control window (PIC window) appeared, when pulmonary infection had been significantly controlled (resolution of fever and decrease in purulent sputum, radiographic infiltrations, and leukocytosis) after the antibiotic and the comprehensive therapy, the early extubation was conducted and followed by non-invasive MV via facial mask immediately in 11 cases (study group). Other 11 COPD cases with similar clinical characteristics who continuously received invasive MV after PIC window were recruited as control group.Results All patients had similar clinical characteristics and gas exchange before treatment, as well as the initiating time and all indices at the time of the PIC window. For study group and control group, the duration of invasive MV was (7.1±2.9) vs (23.0±14.0) days, respectively, P<0.01. The total duration of ventilatory support was (13±7) vs (23±14) days, respectively, P<0.05. The incidence of ventilator associated pneumonia (VAP) were 0/11 vs 6/11, respectively, P<0.01. The duration of intensive care unit (ICU) stay was (13±7) vs (26±14) days, respectively, P<0.05. Conclusions In COPD patients requiring intubation and MV for pulmonary infection and hypercapnic respiratory failure, early extubation followed by non-invasive MV initiated at the point of PIC window significantly decreases the invasive and total durations of ventilatory support, the risk of VAP, and the duration of ICU stay.

    Objective:To explore the efficacy of noninvasive ventilator of ICU in the treatment of COPD merged with type II respiratory failure. Methods:A total of 70 patients with COPD merged with type II respiratory failure were randomized into the observation group and the control group. The patients in the two groups were given anti-infection, cough relieving, phlegm dispersing, asthma relieving, cardiac function improving, electrolyte disturbance and acid-base balance correcting, and appropriate nursing interventions. The patients in the control group were given low-flow oxygen inhalation, while the patients in the observation group were given additional noninvasive ventilator for mask assisted ventilation through the mouth and nose. The changes of PaO2, PaCO2, SaO2, RR, and HR before treatment, and 3d after treatment were detected. The efficacy was evaluated, and the adverse reactions were observed. Results:After treatment, PaO2 and SaO2 in the two groups were elevated, while PaCO2 was reduced when compared with before treatment, and those in the observation group were significantly superior to those in the control group. After treatment, RR and HR were reduced, and those in the observation group were significantly superior to those in the control group. The total effective rate in the observation group was significantly higher than that in the control group (57.1%). And the comparison of the adverse reactions between the two groups was not statistically significant. Conclusions:ICU noninvasive ventilator in the treatment of COPD merged with type II respiratory failure can effectively improve hypoxia and CO2 retention, and rapidly relieve dyspnea, in combined with appropriate nursing intervention can guarantee the successful treatment.

    Full Text Available Protease inhibitors, used as treatment in human immunodeficiency virus (HIV infection, are associated with a syndrome of peripheral lipodystrophy, central adiposity, hyperlipidemia and insulin resistance. An HIV-positive patient with chronic obstructive pulmonary disease is presented who developed the lipodystrophy syndrome that is associated with the use of protease inhibitors. It is postulated that the lipodystrophy syndrome further compromised his lung function, leading to respiratory failure. Patients who have pulmonary disease and are taking protease inhibitors require monitoring of clinical status and pulmonary function tests.

  2. Is there a threshold concentration of cat allergen exposure on respiratory symptoms in adults?

    Directory of Open Access Journals (Sweden)

    Chih-Mei Chen

    Full Text Available Cat allergen concentrations higher than 8 μg/g in settled house dust, have been suggested to provoke exacerbation of allergic respiratory symptoms. However, whether the 8 μg/g of indoor cat allergen concentration is indeed the minimal exposure required for triggering the asthma related respiratory symptoms or the development of sensitization has not yet been confirmed. We studied the associations between domestic cat allergen concentrations and allergic symptoms in the European Community Respiratory Health Survey II, with the aim of confirming this suggested threshold.Cat allergen concentrations were measured in the mattress dust of 3003 participants from 22 study centres. Levels of specific immunoglobulin E to cat allergens were measured in serum samples using an immunoassay. Information on allergic symptoms, medication use, home environment and smoking was obtained from a face-to-face interview.Domestic cat allergen concentrations were not associated with allergic/ asthmatic symptoms in the entire study population, nor in the subset sensitized to cat allergen. We also found no association among individuals exposed to concentrations higher than 8 μg/g. However, exposure to medium cat allergen concentrations (0.24-0.63 μg/g was positively associated with reported asthmatic respiratory symptoms in subjects who have experienced allergic symptoms when near animals.The proposed 8 μg/g threshold of cat allergen concentrations for the exacerbation of allergic/ respiratory symptoms was not confirmed in a general European adult population. Potential biases attributable to avoidance behaviours and an imprecise exposure assessment cannot be excluded.

    Parvovirus B19 induced acute hepatitis and hepatic failure have been previously reported,mainly in children.Very few cases of parvovirus induced hepatic failure have been reported in adults and fewer still have required liver transplantation.We report the case of a 55-year-old immunocompetent woman who developed fulminant hepatic failure after acute infection with Parvovirus B19 who subsequently underwent orthotopic liver transplantation.This is believed to be the first reported case in the literature in which an adult patient with fulminant hepatic failure associated with acute parvovirus B19 infection and without hematologic abnormalities has been identified prior to undergoing liver transplantation.This case suggests that Parvovirus B19 induced liver disease can affect adults,can occur in the absence of hematologic abnormalities and can be severe enough to require liver transplantation.

    Full Text Available Oscillations of arterial pressure occur spontaneously at a frequency of approx. 0.1Hz coupled with synchronous oscillations of sympathetic nerve activity (Mayer waves. This study investigated the extent to which corresponding oscillations may occur in ventricular action potential duration (APD.14 ambulatory (outpatient heart failure patients with biventricular pacing devices were studied while seated upright watching movie clips to maintain arousal. Activation recovery intervals (ARI as a measure of ventricular APD were obtained from unipolar electrograms recorded from the LV epicardial pacing lead during steady state RV pacing from the device. Arterial blood pressure was measured non-invasively (Finapress and respiration monitored. Oscillations were quantified using time frequency and coherence analysis.Oscillatory behaviour of ARI at the respiratory frequency was observed in all subjects. The magnitude of the ARI variation ranged from 2.2 ms to 6.9 ms (mean 5.0 ms. Coherence analysis showed a correlation with respiratory oscillation for an average of 43% of the recording time at a significance level of p < 0.05. Oscillations in systolic blood pressure in the Mayer wave frequency range were observed in all subjects for whom blood pressure was recorded (n=13. ARI oscillation in the Mayer wave frequency range was observed in 6/13 subjects (46% over a range of 2.9ms to 9.2ms. Coherence with Mayer waves at the p < 0.05 significance level was present for an average of 29 % of the recording time. In ambulatory patients with heart failure during enhanced mental arousal, left ventricular epicardial APD (ARI oscillated at the respiratory frequency (approx. 0.25Hz. In 6 patients (46% APD oscillated at the slower Mayer wave frequency (approx. 0.1 Hz. These findings may be important in understanding sympathetic activity-related arrhythmogenesis.

    Full Text Available Helmy Haja Mydin, Stephen Murphy, Howell Clague, Kishore Sridharan, Ian K TaylorDepartment of Respiratory Medicine, Sunderland Royal Infirmary, Sunderland, United KingdomBackground: In patients with acute hypercapnic respiratory failure (AHRF during exacerbations of COPD, mortality can be high despite noninvasive ventilation (NIV. For some, AHRF is terminal and NIV is inappropriate. However there is no definitive method of identifying patients who are unlikely to survive. The aim of this study was to identify factors associated with inpatient mortality from AHRF with respiratory acidosis due to COPD.Methods: COPD patients presenting with AHRF and who were treated with NIV were studied prospectively. The forced expiratory volume in 1 second (FEV1, World Health Organization performance status (WHO-PS, clinical observations, a composite physiological score (Early Warning Score, routine hematology and biochemistry, and arterial blood gases prior to commencing NIV, were recorded.Results: In total, 65 patients were included for study, 29 males and 36 females, with a mean age of 71 ± 10.5 years. Inpatient mortality in the group was 33.8%. Mortality at 30 days and 12 months after admission were 38.5% and 58.5%, respectively. On univariate analysis, the variables associated with inpatient death were: WHO-PS ≥ 3, long-term oxygen therapy, anemia, diastolic blood pressure < 70 mmHg, Early Warning Score ≥ 3, severe acidosis (pH < 7.20, and serum albumin < 35 g/L. On multivariate analysis, only anemia and WHO-PS ≥ 3 were significant. The presence of both predicted 68% of inpatient deaths, with a specificity of 98%.Conclusion: WHO-PS ≥ 3 and anemia are prognostic factors in AHRF with respiratory acidosis due to COPD. A combination of the two provides a simple method of identifying patients unlikely to benefit from NIV.Keywords: acute exacerbations of COPD, noninvasive ventilation, emphysema, prognostic markers

    Full Text Available To determine the outcome of severe dengue viral infection (DVI and the main dengue fatality risk factors.The medical records of patients aged <15 years admitted to Songklanagarind Hospital in southern Thailand during 1989-2011 were reviewed. Patients who had dengue hemorrhagic fever (DHF grades III-IV, organ failure (cardiovascular, respiratory, liver, renal or hematologic, impaired consciousness, or aspartate aminotransferase more than 1,000 units/L, were classified as having severe DVI. To determine the fatality risk factors of severe DVI, the classification trees were constructed based on manual recursive partitioning.Of the 238 children with severe DVI, 30 (12.6% died. Compared to the non-fatal DVI cases, the fatal cases had higher rates of DHF grade IV (96.7% vs 24.5%, repeated shock (93.3% vs 27.9%, acute respiratory failure (ARF (100% vs 6.7%, acute liver failure (ALF (96.6% vs 6.3%, acute kidney injury (AKI (79.3% vs 4.5%, and active bleeding requiring blood transfusion (93.3% vs 5.4%, all p<0.01. The combined risk factors of ARF and active bleeding considered together predicted fatal outcome with sensitivity, specificity, and negative and positive predictive values of 0.93 (0.78-0.99, 0.97 (0.93-0.99, 0.99 (0.97-1.00, and 0.82 (0.65-0.93, respectively. The likelihood ratios for a fatal outcome in the patients who had and did not have this risk combination were 32.4 (14.6-71.7 and 0.07 (0.02-0.26, respectively.Severe DVI patients who have ARF and active bleeding are at a high risk of death, while patients without these things together should survive.

  14. Potential therapeutic application of adult stem cells in acute respiratory distress syndrome

    2009-01-01

    Acute respiratory distress syndrome (ARDS) remains a poor prognosis in spite of the recent development of new therapeutic strategies. Cell-based therapy with stem cells has been considered as a promising way for the treatment of vital organ damage. Putative endogenous stem cells have been shown to be located within the adult lung in the basal layer of the upper airways, within or near pulmonary neu-roendocrine cell rests, at the bronchoalveolar junction, as well as within the alveolar epithelium. These stem cells are hypothesized to be the source of lung regeneration and repair. But this mechanism seems to be insufficient after lung injury. There is increasing excitement over the last few years with the suggestion that exogenous stem cells may offer new treatment options for ARDS. Exogenous stem cells have the abihty to differentiate and function as both airway and lung parenchymal epithelial cells in both in vitro and in-creasingly in vivo experiments. However, there is great con-troversy concerning the repair effect of adult stem cells in lung injury. This review evaluates the advances in endog-enous respiratory stem cells, and assesses the evidence for the use of stem cells in the repair of lung injury.

    Rhinovirus infections occur frequently throughout life and have been reported in about one-third of asymptomatic cases. The clinical significance of sequential rhinovirus infections remains unclear. To determine the incidence and clinical relevance of sequential rhinovirus detections, nasopharyngeal samples from 2485 adults with acute cough/lower respiratory illness were analysed. Patients were enrolled prospectively by general practitioners from 12 European Union countries during three consecutive years (2007-2010). Nasopharyngeal samples were collected at the initial general practitioner consultation and 28 days thereafter and symptom scores were recorded by patients over that period. Rhinovirus RNA was detected in 444 (18%) out of 2485 visit one samples and in 110 (4.4%) out of 2485 visit two respiratory samples. 21 (5%) of the 444 patients had both samples positive for rhinovirus. Genotyping of both virus detections was successful for 17 (81%) out of 21 of these patients. Prolonged rhinovirus shedding occurred in six (35%) out of 21 and re-infection with a different rhinovirus in 11 (65%) out of 21. Rhinovirus re-infections were significantly associated with chronic obstructive pulmonary disease (p=0.04) and asthma (p=0.02) and appeared to be more severe than prolonged infections. Our findings indicate that in immunocompetent adults rhinovirus re-infections are more common than prolonged infections, and chronic airway comorbidities might predispose to more frequent rhinovirus re-infections.

    A 4-year-old boy with atrioventricular discordance, double-outlet right ventricle, pulmonary stenosis, and mitral regurgitation, was undergoing anatomical repair consisting of Senning, Rastelli, Damus-Kaye-Stansel procedures, and a mitral valve repair, complained of post-operative excessive airway tract secretion, which ultimately developed into acute respiratory distress syndrome (ARDS) 28 days after the operation. The cause of the ARDS was thought to be frequent manual positive pressure recruitment and prolonged inhalation of pure oxygen. At 45 days after the operation, hypercapnia and respiratory acidosis turned out to be irreversible, and therefore, veno-arterial extracorporeal membrane oxygenation (ECMO) was established utilizing the Endumo(®)4000 system. Pulmonic interstitial inflammation gradually improved while resting the lung under ECMO support; however, effective ventilation volume decreased critically because a massive pulmonary hemorrhage occurred at 2 and 9 days after the initiation of ECMO. To maximize the effectiveness of respiratory physical therapy, "Awake ECMO" was started and tidal volume dramatically increased with a regained cough reflex. Five days later, he was successfully weaned off from ECMO, and discharged 7 months after the operation without any neurological and physiological sequelae.

    The 'epidemic' of heart failure seems to be changing, but precise prevalence estimates of heart failure and left ventricular dysfunction (LVD) in older adults, based on adequate echocardiographic assessment, are scarce. Systematic reviews including recent studies on the prevalence of heart failure and LVD are lacking. We aimed to assess the trends in the prevalence of LVD, and heart failure with reduced (HFrEF) and preserved ejection fraction (HFpEF) in the older population at large. A systematic electronic search of the databases Medline and Embase was performed. Studies that reported prevalence estimates in community-dwelling people ≥60 years old were included if echocardiography was used to establish the diagnosis. In total, 28 articles from 25 different study populations were included. The median prevalence of systolic and 'isolated' diastolic LVD was 5.5% (range 3.3-9.2%) and 36.0% (range 15.8-52.8%), respectively. A peak in systolic dysfunction prevalence seems to have occurred between 1995 and 2000. 'All type' heart failure had a median prevalence rate of 11.8% (range 4.7-13.3%), with fairly stable rates in the last decade and with HFpEF being more common than HFrEF [median prevalence 4.9% (range 3.8-7.4%) and 3.3% (range 2.4-5.8%), respectively]. Both LVD and heart failure remain common in the older population at large. The prevalence of diastolic dysfunction is on the rise and currently higher than that of systolic dysfunction. The prevalence of the latter seems to have decreased in the 21st century.

    Introduction: Extracorporeal membrane oxygenation (ECMO) has been extensively used for potentially reversible acute respiratory failure associated with severe influenza A (H1N1) pneumonia; however, it remains an expensive, resource-intensive therapy, with a high associated mortality. This systematic review and meta-analysis aims to summarize and pool outcomes data available in the published literature to guide clinical decision-making and further research. Methods: We conducted a systematic search of MEDLINE (1966 to April 15, 2015), EMBASE (1980 to April 15, 2015), CENTRAL, and Google Scholar for patients with severe H1N1 pneumonia and respiratory failure who received ECMO. The study validity was appraised by Newcastle–Ottawa Scale. The primary outcome was all-cause mortality. The secondary outcomes were duration of ECMO therapy, mechanical ventilation, and Intensive Care Unit (ICU) length of stay. Results: Of 698 abstracts screened and 142 full-text articles reviewed, we included 13 studies with a total of 494 patients receiving ECMO in our final review and meta-analysis. The study validity was satisfactory. The overall mortality was 37.1% (95% confidence interval: 30–45%) limited by underlying heterogeneity (I2 = 65%, P value of Q statistic = 0.006). The median duration for ECMO was 10 days, mechanical ventilation was 19 days, and ICU length of stay was 33 days. Exploratory meta-regression did not identify any statistically significant moderator of mortality (P < 0.05), except for the duration of pre-ECMO mechanical ventilation in days (coefficient 0.19, standard error: 0.09, Z = 2.01, P < 0.04, R2 = 0.16). The visual inspection of funnel plots did not suggest the presence of publication bias. Conclusions: ECMO therapy may be used as an adjunct or salvage therapy for severe H1N1 pneumonia with respiratory failure. It is associated with a prolonged duration of ventilator support, ICU length of stay, and high mortality. Initiating ECMO early once the patient

    Full Text Available CANOMAD is a rare chronic neuropathy, characterized by chronic sensory ataxia and intermittent brain stem symptoms due to antidisialosyl antibodies. The disorder results in significant morbidity but is poorly understood and often misdiagnosed. We describe a unique case of CANOMAD, associated with involuntary movements of the face; patient reported exacerbations with citrus and chocolate and respiratory muscle weakness. Our patient was initially misdiagnosed with Miller Fisher Syndrome, highlighting the need for vigilance should neurological symptoms recur in patients initially diagnosed with a Guillain Barre variant. Moreover, the optimal treatment is unknown. This patient responded remarkably to intravenous immunoglobulin and has been maintained on this treatment, without further exacerbations.

    Full Text Available Abstract We present a case of severe interstitial pneumonitis, mild polyarthritis and polymyositis, and Raynaud's syndrome with the presence of anti-Jo-1 antibodies, which had been diagnosed as anti-synthetase syndrome. The presence, however, of anti-Ro/SSA antibodies led us to understand that we were dealing here with a more severe form of interstitial lung disease. The patient was treated for acute respiratory failure but he showed resistance to glucocorticoids and cyclosporine. Thus, he was treated with infusions of anti-CD20 therapy (rituximab: his clinical conditions improved very rapidly and a significant decrease in the activity of pulmonary disease was detected using high-resolution computerized tomography (HRCT of the thorax and pulmonary function tests.

    Full Text Available Vasculotoxic snake bites are well known to cause local complications like necrosis and cellulitis and systemic complications such as coagulopathy, acute renal failure (ARF, and hemolysis. We report a case of young female patient who was bitten by a viper. She developed cellulitis, sepsis, ARF, and Disseminated Intravascular Coagulation. She was treated for the above complications and all her renal and hematological parameters returned to normal on seventh day. After this, on the same day, patient developed Acute Respiratory Distress Syndrome probably due to the direct toxic effect of venom on pulmonary vascular endothelium which has been reported as a late complication of snake venom. With close monitoring and proper management of complications, the patient recovered and walked out of the hospital on the twenty first day without any complications.

    Sleeping and resting respiratory rates (SRR and RRR, respectively) are commonly used to monitor dogs and cats with left-sided cardiac disease and to identify animals with left-sided congestive heart failure (L-CHF). Dogs and cats with subclinical heart disease have SRRmean values 40 breaths/min. Median feline RRRmean was 24 breaths/min (15-45 breaths/min); five cats had RRRmean ≥25 breaths/min; one had ≥30 breaths/min, and two had ≥40 breaths/min. These data suggest that most dogs and cats with CHF that is medically well-controlled and stable have SRRmean and RRRmean <30 breaths/min at home. Clinicians can use these data to help determine how best to control CHF in dogs and cats.

    Magnesium is known to act at the neuromuscular junction by inhibiting the presynaptic release of acetylcholine and desensitizing the postsynaptic membrane. Because of these effects, magnesium has been postulated to potentiate neuromuscular weakness. We describe the case of a 62-year-old woman with myasthenia gravis and a metastatic thymoma who was admitted to our intensive care unit for management of a myasthenic crisis. The patient's neuromuscular weakness worsened in association with standard intravenous magnesium replacement, and the exacerbated respiratory failure necessitated intubation, mechanical ventilation, and an extended stay in the intensive care unit. The effect of magnesium replacement on myasthenia gravis patients has not been well documented, and we present this case to increase awareness and stimulate research. In addition, we discuss the relevant medical literature.

    A 27-year-old woman was admitted to our ICU with acute hypoxemic respiratory failure and criteria for ARDS. Despite an F(IO(2)) of 1.0 and a lung protective strategy, the patient died on day 15 without any improvement. The relatives gave consent for post-mortem analysis. The histopathologic study of the lung showed findings typical of an acute fibrinous and organizing pneumonia. Apropos of this case we performed a PubMed search. We found 13 articles, including a total of 29 patients. Acute fibrinous and organizing pneumonia is an unusual cause of acute lung injury. The diagnostic criterion is histopathologic. There is little information regarding the pathophysiology of this illness. Important questions remain regarding this disease, including predisposing factors and management. Patients who require mechanical ventilation have poor outcomes.

    Full Text Available Polymyositis is a systemic, inflammatory muscle disease. Respiratory insufficiency as a result of respiratory muscle involvement could also be observed. Here we report a fortyone-year-old man who attended to the hospital with the complaints of shortness of breath and chest pain that have suddenly started. Physical examination has revealed proximal muscle weakness. Serum creatinine phosphokinase level has increased, ANA was positive and the electromyographic examination has revealed myopathic changes. Deltoid muscle biopsy was in accordance with polymyositis. Methyl-prednisolone 1 gram iv pulse therapy was given during the first 5 days. He was started with 25 mg/week parenteral methotrexate. Laboratory tests suggested hypothyroidism and levothyroxine replacement therapy was started. The clinical findings have improved concomitant with the reduction in the muscle enzymes and thyroid stimulant hormone levels into the normal ranges. He was discharged with the recommendation of the NIMV device application during night-time. The clinical symptoms are more severe in the presence of alveolar hypoventilation due to polymyositis and coincidantal hypothyroidism. [Cukurova Med J 2013; 38(4.000: 744-750

    Quality of life and prognosis of patients with myotonic dystrophy type 1 (MD1) often depend on the degree of lung function impairment. This study was designed to assess the respective prevalence of ventilatory restriction, hypoxaemia and hypercapnia in MD1 patients and to determine whether postural changes in lung function could contribute to the early diagnosis of poor respiratory outcome. Fifty-eight patients (42.6±12.9 years) with MD1 were prospectively evaluated from April 2008 to June 2010 to determine their supine and upright lung function and arterial blood gases. The prevalence of ventilatory restriction was 36% and increased with the severity of muscular disability (from 7.7% to 70.6%). The prevalence of hypoxaemia and hypercapnia was 37.9% and 25.9%, respectively. Multiple regression analysis showed that the supine fall in FEV1 was the only variable associated with ventilatory restriction, hypoxaemia and hypercapnia. Our data indicate that supine evaluation of lung function could be helpful to predict poor respiratory outcome, which is closely correlated with hypoxaemia and/or hypercapnia.

    Morphological alterations of the lung in respiratory distress syndrome of adults (ARDS) were analyzed in 10 cases with traumatic-and septic shock, laryngitis subglottica descendens and bronchopneumonia. For the better understanding of the pathomechanism of the disease in addition to the standard methods, first of all ultrastructural alterations were studied. Two phases of the morphologic alterations could be distinguished, the phase of the destruction and the phase of the repair. These two processes are not sharply distinguishable. Genesis of the characteristic histological alterations (damage to the epithelial and endothelial cells, formation of hyaline membranes, microcoagulation, proliferation of the type II pneumocytes and fibroblasts, fibrosis) is discussed, with regard to the data of the literature.

    2016-01-01

    Full Text Available Antisynthetase (AS syndrome is a major subgroup of inflammatory myopathies seen in a minority of patients with dermatomyositis and polymyositis. Although it is usually associated with elevated creatine phosphokinase level, some patients may have amyopathic dermatomyositis (ADM like presentation with predominant skin involvement. Interstitial lung disease (ILD is the main pulmonary manifestation and may be severe thereby determining the prognosis. It may rarely present with a very aggressive course resulting in acute respiratory distress syndrome (ARDS. We report a case of a 43-year-old male who presented with nonresolving pneumonia who was eventually diagnosed to have ADM through a skin biopsy without any muscle weakness. ADM may be associated with rapidly progressive course of interstitial lung disease (ADM-ILD which is associated with high mortality. Differentiation between ADM-ILD and AS syndrome may be difficult in the absence of positive serology and clinical presentation may help in clinching the diagnosis.

    Full Text Available Ovarian hyperstimulation syndrome (OHSS was first described in 1960. It may occur as a complication of gonadotropin hormone therapy during assisted pregnancy or for primary infertility. A 26-year-old female patient with polycystic ovarian syndrome and primary infertility was treated to conceive. She received intravenous gonadotropin-releasing hormone (GnRH along with follicle-stimulating hormone in an outside private clinic. She presented to the emergency department with abdominal and chest pain, loose stool, vomiting, shortness of breath and decreasing urine output. She was found to have edema, ascites, effusion and acute kidney injury (AKI. Considering the symptoms preceding the drug history and anasarca, a diagnosis of severe OHSS was made. Ascites was further complicated by spontaneous bacterial peritonitis (SBP, which had already been reported before. We speculate that low immunity due to decreased immunoglobulin in patients with OHSS makes them prone to SBP. In our case, septicemia secondary to SBP and fluid loss due to capillary leakage from OHSS resulted in AKI and respiratory failure. This critically ill patient was treated in a special care unit, and she fully recovered with supportive measures. Severe OHSS may present as anasarca including ascites which can develop SBP leading to sepsis and multiorgan failure.

    Full Text Available Objective. To present a case of a healthy 41-year-old female who developed fulminant hepatic failure leading to death. The cause of hepatic failure identified on postmortem exam was herpes simplex virus hepatitis. Design. Observation of a single patient. Setting. Intensive care unit of a tertiary care university teaching hospital in Canada. Patient. 41-year-old previously healthy female presenting with a nonspecific viral illness and systemic inflammatory response syndrome. Intervention. The patient was treated with intravenous fluids and broad-spectrum antibiotics. On the second day of admission, she was found to have elevated transaminases, and, over 48 hours, she progressed to fulminant liver failure with disseminated intravascular coagulopathy, refractory lactic acidosis, and shock. She progressed to respiratory failure requiring intubation and mechanical ventilation. She was started on N-acetylcysteine, a bicarbonate infusion, hemodialysis, and multiple vasopressors and inotropes. Measurements and Main Results. Despite treatment, the patient died roughly 70 hours after her initial presentation to hospital. Her postmortem liver biopsy revealed herpes simplex virus hepatitis as her cause of death. Conclusions. Herpes simplex virus must be considered in all patients presenting with liver failure of unknown cause. If suspected, prompt treatment with acyclovir should be initiated.

    1995-01-01

    The adult respiratory distress syndrome (ARDS) in children has a very poor prognosis with a mortality risk of between 55 and 85%, in spite of improvements due to the introduction of positive endexpiratory pressure ventilation. We describe the clinical course of a not yet 3 year-old boy with severe ARDS following near-drowing. Treatment with exogenous surfactant and high frequency oscillatory ventilation, a well-established procedure in neonatology, was responsible for the favorable outcome. The high cost of surfactant therapy, however, is the main limiting factor for this kind of treatment in children beyond the neonatal period, but it may be the last therapeutic resort in the management of severe ARDS.

    We reviewed the medical records of 123 adult reduced-intensity cord blood transplantation (RI-CBT) recipients to investigate the clinical features of graft failure after RI-CBT. Nine (7.3%) had graft failure, and were classified as graft rejection rather than primary graft failure; they showed peripheral cytopenia with complete loss of donor-type haematopoiesis, implying destruction of donor cells by immunological mechanisms rather than poor graft function. Three of them died of bacterial or fungal infection during neutropenia. Two recovered autologous haematopoiesis. The remaining four patients underwent a second RI-CBT and developed severe regimen-related toxicities. One died of pneumonia on day 8, and the other three achieved engraftment. Two of them died of transplant-related mortality, and the other survived without disease progression for 9.0 months after the second RI-CBT. In total, seven of the nine patients with graft failure died. The median survival of those with graft failure was 3.8 months (range, 0.9-15.4). Graft failure is a serious complication of RI-CBT. As host T cells cannot completely be eliminated by reduced-intensity preparative regimens, we need to be aware of the difficulty in differentiating graft rejection from other causes of graft failure following RI-CBT. Further studies are warranted to establish optimal diagnostic and treatment strategies.

    Full Text Available Abstract Background Health-related quality of life (HRQL is considered as an important outcome parameter in patients with chronic diseases. This study aimed to assess the role of disease-specific HRQL for long-term survival in patients of different diagnoses with chronic hypercapnic respiratory failure (CHRF. Methods In a cohort of 231 stable patients (chronic obstructive pulmonary disease (COPD, n = 98; non-COPD (obesity-hypoventilation syndrome, restrictive disorders, neuromuscular disorders, n = 133 with CHRF and current home mechanical ventilation (HMV, HRQL was assessed by the disease-specific Severe Respiratory Insufficiency (SRI questionnaire and its prognostic value was prospectively evaluated during a follow-up of 2–4 years, using univariate and multivariate regression analysis. Results HRQL was more impaired in COPD (mean ± SD SRI-summary score (SRI-SS 52.5 ± 15.6 than non-COPD patients (67.6 ± 16.4; p 1 turned out to be independent predictors (p Conclusion In patients with CHRF and HMV, the disease-specific SRI was an overall predictor of long-term survival in addition to established risk factors. However, the SRI predominantly beared information regarding long-term survival in non-COPD patients, while in COPD patients objective measures of the disease state were superior. This on one hand highlights the significance of HRQL in the long-term course of patients with CHRF, on the other hand it suggests that the predictive value of HRQL depends on the underlying disease.

    Full Text Available Patients with chronic obstructive pulmonary disease (COPD are susceptible to airway malacia, which may be unmasked following mechanical ventilation or tracheostomy decannulation. Dynamic imaging of central airways, a non-invasive test as effective as bronchoscopy to diagnose airway malacia, has increased the recognition of this disorder. We describe a 70-year-old woman admitted with adult respiratory distress syndrome. She had cardiorespiratory arrest on admission, from which she was successfully resuscitated. She had obesity, hypertension, diabetes mellitus, recurrent ventricular tachycardia, sarcoidosis with interstitial lung disease and COPD. She received short-term (18 days mechanical ventilation with tracheostomy and developed respiratory distress following tracheostomy decannulation.

  2. Alveolar macrophages are essential for protection from respiratory failure and associated morbidity following influenza virus infection.

    2014-04-01

    Full Text Available Alveolar macrophages (AM are critical for defense against bacterial and fungal infections. However, a definitive role of AM in viral infections remains unclear. We here report that AM play a key role in survival to influenza and vaccinia virus infection by maintaining lung function and thereby protecting from asphyxiation. Absence of AM in GM-CSF-deficient (Csf2-/- mice or selective AM depletion in wild-type mice resulted in impaired gas exchange and fatal hypoxia associated with severe morbidity to influenza virus infection, while viral clearance was affected moderately. Virus-induced morbidity was far more severe in Csf2-/- mice lacking AM, as compared to Batf3-deficient mice lacking CD8α+ and CD103+ DCs. Csf2-/- mice showed intact anti-viral CD8+ T cell responses despite slightly impaired CD103+ DC development. Importantly, selective reconstitution of AM development in Csf2rb-/- mice by neonatal transfer of wild-type AM progenitors prevented severe morbidity and mortality, demonstrating that absence of AM alone is responsible for disease severity in mice lacking GM-CSF or its receptor. In addition, CD11c-Cre/Ppargfl/fl mice with a defect in AM but normal adaptive immunity showed increased morbidity and lung failure to influenza virus. Taken together, our results suggest a superior role of AM compared to CD103+ DCs in protection from acute influenza and vaccinia virus infection-induced morbidity and mortality.

    This study examined the relationship between spiritual well-being (SWB) and perceived control (PC) in adult patients with heart failure (HF). The sample included 75 adults ranging in age from 27 to 82 years. Participants verbally completed study questionnaires in a clinic room selected for privacy. Multiple linear regression results indicated that increased existential spiritual well-being (a subscale of SWB) predicted increased PC. Thus, patients with HF who adjust to personal changes and who also connect with others may develop meaning and purpose in life and may perceive increased control over their heart disease.

    Aim: To evaluate the extent to which single measurements of microvascular lung permeability may be relevant as an additional parameter in a heterogenous clinical patient collective with Acute Lung Injury (ALI) and Acute Respiratory Distress Syndrome (ARDS). Methods: In 36 patients with pneumonia (13), non pneumogenic sepsis (9) or trauma (14) meeting the consensus conference criteria of ALI or ARDS double-isotope protein flux measurements ({sup 51}Cr erythrocytes as intravascular tracer, Tc-99m human albumin as diffusible tracer) of microvascular lung permeability were performed using the Normalized Slope Index (NSI). The examination was to determine whether there is a relationship between the clinical diagnosis of ALI/ARDS, impaired permeability and clinical parameters, that is the underlying disease, oxygenation, duration of mechanical ventilation and mean pulmonary-artery pressure (PAP). Results: At the time of study, 25 patients presented with increased permeability (NSI > 1 x 10{sup -3} min{sup -1}) indicating an exudative stage of disease, and 11 patients with normal permeability. The permeability impairment correlated with the underlying disease (p > 0.05). With respect to survival, there was a negative correlation to PAP (p < 0.01). Apart from that no correlations between the individual parameters were found. Especially no correlation was found between permeability impairment and oxygenation, duration of disease of PAP. Conclusion: In ALI and ARDS, pulmonary capillary permeability is a diagnostic parameter which is independent from clinical variables. Permeability measurement makes a stage classification (exudative versus non exudative phase) of ALI/ARDS possible based on a measurable pathophysiological correlate. (orig.)

    Full Text Available Background: Shock includes different pathophysiological mechanisms not fully understood and remains a challenge to manage. Exhaled breath condensate (EBC may contain relevant biomarkers that could help us make an early diagnosis or better understand the metabolic perturbations resulting from this pathological situation. Objective: we aimed to establish the metabolomics signature of EBC from patients in shock with acute respiratory failure in a pilot study. Material and methods: We explored the metabolic signature of EBC in 12 patients with shock compared to 14 controls using LC-HRMS. We used a non-targeted approach, and we performed a multivariate analysis based on Orthogonal Partial Least Square-Discriminant Analysis (OPLS-DA to differentiate between the two groups of patients. Results: We optimized the procedure of EBC collection and LC-HRMS detected more than 1000 ions in this fluid. The optimization of multivariate models led to an excellent model of differentiation for both groups (Q2 > 0.4 after inclusion of only 6 ions. Discussion and conclusion: We validated the procedure of EBC collection and we showed that the metabolome profile of EBC may be relevant in characterizing patients with shock. We performed well in distinguishing these patients from controls, and the identification of relevant compounds may be promising for ICC patients.

Exhaled breath condensate (EBC) may contain relevant biomarkers that could help us make an early diagnosis or better understand the metabolic perturbations resulting from this pathological situation. Objective: we aimed to establish the metabolomics signature of EBC from patients in shock with acute respiratory failure in a pilot study. Material and methods: We explored the metabolic signature of EBC in 12 patients with shock compared to 14 controls using LC-HRMS. We used a non-targeted approach, and we performed a multivariate analysis based on Orthogonal Partial Least Square-Discriminant Analysis (OPLS-DA) to differentiate between the two groups of patients. Results: We optimized the procedure of EBC collection and LC-HRMS detected more than 1000 ions in this fluid. The optimization of multivariate models led to an excellent model of differentiation for both groups (Q2 > 0.4) after inclusion of only 6 ions. Discussion and conclusion: We validated the procedure of EBC collection and we showed that the metabolome profile of EBC may be relevant in characterizing patients with shock. We performed well in distinguishing these patients from controls, and the identification of relevant compounds may be promising for ICC patients. PMID:27598216

    Full Text Available This study was concerned with the comparative evaluation of the morphologic and morphometric parameters of the lower respiratory tract of Japanese quail and that of pigeon. In the course of this work twenty birds (ten pigeons and ten Japanese quails of both sexes were purchased from a poultry market in Sokoto metroplis, Sokoto, Nigeria and used. It was observed in this study that the lower respiratory tract extended from the caudal part of the oral cavity (around the larynx down to the neck and to the thoracic region. The lower respiratory tract structures were the trachea (including the syrinx, the bronchus and the lungs. In the study, all the birds used were adults with mean body weight of 159.51±8.19g and 265.78±4.88g for the Japanese quail and pigeon respectively, this was considered extremely significant (P

    Full Text Available BACKGROUND: Inhaled nitric oxide (iNO reduces death or need for extracorporeal membrane oxygenation (ECMO in infants with persistent pulmonary hypertension of the newborn (PPHN. However, the response to iNO is variable and only 50-60% of infants demonstrate a response to iNO. It is not known why only some infants respond to iNO. Adults and children with blood groups B or AB do not respond as well to iNO as those with blood groups O/A. METHODS/PRINCIPAL FINDINGS: To determine if blood group was associated with iNO response in newborn infants, a retrospective medical record review was done of infants admitted to a regional NICU from 2002-9 with a diagnosis of PPHN. Data were collected during the first twelve hours post-initiation of treatment. Of 86 infants diagnosed with PPHN, 23 infants had blood group A [18 received iNO], 21 had group B [18 with iNO], 40 had group O [36 with iNO], and 2 had group AB [both received iNO]. Change in PaO(2/FiO(2 was less in infants with blood group A, of whom less than half were responders (ΔPaO(2/FiO(2>20% at 12 h versus 90% of infants with either O or B. Race, sex, birth weight, gestational age, Apgar scores at 1 and 5 minutes, and baseline PaO(2/FiO(2 were similar among groups. Outcomes including need for ECMO, death, length of ventilatory support, length of iNO use, and hospital stay were statistically not different by blood groups. CONCLUSIONS/SIGNIFICANCE: Our results indicate that blood group influences iNO response in neonates. We hypothesize that either there is genetic linkage of the ABO gene locus with vasoregulatory genes, or that blood group antigens directly affect vascular reactivity.

    Full Text Available BACKGROUND: Acute respiratory tract infections (ARTIs represent a serious global health burden. To date, few reports have addressed the prevalence of respiratory viruses (RVs in adults with ARTIs attending an emergency department (ED. Therefore, the potential impact of respiratory virus infections on such patients remains unknown. METHODOLOGY/PRINCIPAL FINDINGS: To determine the epidemiological and clinical profiles of common and recently discovered respiratory viruses in adults with ARTIs attending an ED in Beijing, a 1-year consecutive study was conducted from May, 2010, to April, 2011. Nose and throat swab samples from 416 ARTI patients were checked for 13 respiratory viruses using multiple reverse transcription polymerase chain reaction(RT-PCR assays for common respiratory viruses, including influenza viruses (Flu A, B, and adenoviruses (ADVs, picornaviruses (PICs, respiratory syncytial virus (RSV, parainfluenza viruses (PIVs 1-3, combined with real-time RT-PCR for human metapneumovirus (HMPV and human coronaviruses (HCoVs, -OC43, -229E, -NL63, and -HKU1. Viral pathogens were detected in 52.88% (220/416 of patient samples, and 7.21% (30/416 of patients tested positive for more than one virus. PICs (17.79% were the dominant agents detected, followed by FluA (16.11%, HCoVs (11.78%, and ADV (11.30%. HMPV, PIVs, and FluB were also detected (<3%, but not RSV. The total prevalence and the dominant virus infections detected differed significantly between ours and a previous report. Co-infection rates were high for HCoV-229E (12/39, 30.76%, PIC (22/74, 29.73%, ADV (12/47, 25.53% and FluA (15/67, 22.39%. Different patterns of clinical symptoms were associated with different respiratory viruses. CONCLUSIONS: The pattern of RV involvement in adults with ARTIs attending an ED in China differs from that previously reported. The high prevalence of viruses (PIC, FluA, HCoVs and ADV reported here strongly highlight the need for the development of safe and

    In this cohort study we examined whether gender, age at onset, observation time or human papillomavirus (HPV) genotype are risk factors for an aggressive clinical course in Recurrent Respiratory Papillomatosis (RRP). Clinical data from patient records comprised gender, age at onset, date of first endolaryngeal procedure with biopsy, date of last follow-up, total number of endolaryngeal procedures, and complications during the observation period. Disease was defined as juvenile (JoRRP) or adult onset (AoRRP) according to whether the disease was acquired before or after the age of 18. Aggressive disease was defined as distal spread, tracheostomy, four surgical operations annually or >10 surgeries in total. DNA was extracted from formalin-fixed paraffin-embedded tissue. HPV genotyping was performed by quantitative PCR assay identifying 15 HPV genotypes. The study included 224 patients. The majority were males (141/174 in AoRRPs and 31/50 in JoRRPs; p = 0.005). The median follow-up from initial diagnosis was 12.0 years (IQR 3.7-32.9) for JoRRPs and 4.0 years (IQR 0.8-11.7) for AoRRPs. The disease was more aggressive in juveniles than adults (pjuveniles, while HPV11 (OR = 3.74, 95% CI [1.40, 9.97], p = 0.008) and observation time >10 years (OR = 13.41, 95% CI [5.46, 32.99[, p10 years were risk factors for an aggressive disease course in AoRRPs.

  12. Exposure of neonates to Respiratory Syncytial Virus is critical in determining subsequent airway response in adults

    Full Text Available Abstract Background Respiratory syncytial virus (RSV is the most common cause of acute bronchiolitis in infants and the elderly. Furthermore, epidemiological data suggest that RSV infection during infancy is a potent trigger of subsequent wheeze and asthma development. However, the mechanism by which RSV contributes to asthma is complex and remains largely unknown. A recent study indicates that the age of initial RSV infection is a key factor in determining airway response to RSV rechallenge. We hypothesized that severe RSV infection during neonatal development significantly alters lung structure and the pulmonary immune micro-environment; and thus, neonatal RSV infection is crucial in the development of or predisposition to allergic inflammatory diseases such as asthma. Methods To investigate this hypothesis the present study was conducted in a neonatal mouse model of RSV-induced pulmonary inflammation and airway dysfunction. Seven-day-old mice were infected with RSV (2 × 105 TCID50/g body weight and allowed to mature to adulthood. To determine if neonatal RSV infection predisposed adult animals to enhanced pathophysiological responses to allergens, these mice were then sensitized and challenged with ovalbumin. Various endpoints including lung function, histopathology, cytokine production, and cellularity in bronchoalveolar lavage were examined. Results RSV infection in neonates alone led to inflammatory airway disease characterized by airway hyperreactivity, peribronchial and perivascular inflammation, and subepithelial fibrosis in adults. If early RSV infection was followed by allergen exposure, this pulmonary phenotype was exacerbated. The initial response to neonatal RSV infection resulted in increased TNF-α levels in bronchoalveolar lavage. Interestingly, increased levels of IL-13 and mucus hyperproduction were observed almost three months after the initial infection with RSV. Conclusion Neonatal RSV exposure results in long term

    Full Text Available Exacerbation of bronchial asthma (BA and common deterioration of health during chronic bronchiolitis obliterans (ChBO are associated with viral infections in adults in 64 and 83% respectively. Mixed virus-viral associations were shown in 21–25% of cases. Respiratory syncytial infections were diagnosed with the highest frequency (50% in patients with BA. Influenza A(H1N1pdm09 and adenoviral infections dominated in persons with ChBO in 50 and 42% of cases, respectively. Response of virus-specific IgG in patients with BA and ChBO indicates the acute course of influenza A(H1N1pdm09 (63% of seroconversions. There were no reactions of IgG which is specific to respiratory syncytial virus in 75% of cases and to adenovirus in 83% of cases, that is the risk factor for occurrence of latent/persistent infection. Presence of structural components of respiratory syncytial virus in the upper respiratory tract had been revealed in three patients with asthma within at least 21–28 days. Respiratory syncytial viral infections and pandemic influenza A(H1N1 pdm09 in patients with BA and ChBO are characterized by the presence of an allergic component, which is indicated by the high levels of virus-specific IgE in blood. An adenoviral infection, in contrast, has no such peculiarity.

    Full Text Available We describe a case of intraoperative diagnosis and successful deferred percutaneous closure of a patent foramen ovale (PFO in the clinical setting of acute refractory hypoxemic respiratory failure and new-onset ischemic stroke in an elderly patient after coronary artery bypass graft. Perioperative morbidity (i.e. severe hypoxemia, worsening right ventricular dysfunction, and embolic stroke that is potentially related to intraoperatively diagnosed PFO during cardiac surgery can complicate management in the Intensive Care Unit and perhaps affect the patient′s outcome. Although the PFO closure can be challenging in the clinical setting of hypoxemic respiratory failure and stroke following cardiac surgery, it can be a reasonable perioperative option.

    Full Text Available Li Wei,1,2 Yinghui Chen1,2 1Department of Neurology, Jinshan Hospital, 2Department of Neurology, Shanghai Medical College, Fudan University, Shanghai, People's Republic of China Abstract: Neuroleptic malignant-like syndrome (NMLS is a rare but catastrophic complication of drug treatment for Parkinson's disease (PD. Sudden withdrawal and abrupt reduction of antiparkinsonian drugs are major risk factors. Just as its name suggests, the clinical features of NMLS are similar to neuroleptic malignant syndrome, which is a dangerous adverse response to antipsychotic drugs. Both of these conditions can present with hyperthermia, marked muscle rigidity, altered consciousness, autonomic dysfunction, and elevated serum creatine-kinase (CK levels. However, we describe a special NMLS case with a slight elevation of CK levels and respiratory failure in the full course of her treatment. The patient, a 68-year-old woman with a 4-years history of Parkinson's disease, presented with hyperthermia and severe muscular rigidity. During the course of her treatment, her maximum temperature was extremely high (above 41°C. At the beginning, the diagnosis of NMLS secondary to dopamine decrease was difficult to make, because her initial blood examination revealed that her serum CK levels were mildly elevated and decreased to normal range rapidly. Although antiparkinsonian drugs and supportive treatment were applied, the patient developed an acute respiratory failure in the early course of treatment. This case report highlights that when confronted with Parkinson's patients with high body temperature and muscle rigidity, NMLS should be taken into consideration even if there is no CK elevation. Likewise, the need for supportive care is essential, because its complications are severe, even such as respiratory failure.

    Clinical reports on management and rewarming complications after prolonged avalanche burial are not common. We present a case of an unreported combination of respiratory failure and unexpected spontaneous hypoglycemia during noninvasive rewarming from severe hypothermia. We collected anecdotal observations in a 42-year-old, previously healthy, male backcountry skier admitted to the ICU at a tertiary care center after 2 hours 7 minutes of complete avalanche burial, who presented with a patent airway and a core body temperature of 25.0°C (77.0°F) on extrication. There was no decrease in core body temperature during transport (from 25.0°C [77.0°F] to 24.7°C [76.5°F]). Atrial fibrillation occurred during active noninvasive external rewarming (to 37.0°C [98.6°F] during 5 hours), followed by pulmonary edema and respiratory failure (SaO(2) 73% and PaO(2)/FIO(2) 161 mm Hg), which resolved with endotracheal intubation and continuous positive end-respiratory pressure. Moreover, a marked spontaneous glycemic imbalance (from 22.2 to 1.4 mmol/L) was observed. Despite a possible favorable outcome, clinicians should be prepared to identify and treat severe respiratory problems and spontaneous hypoglycemia during noninvasive rewarming of severely hypothermic avalanche victims.

    Full Text Available Household air pollution (HAP contributes to the global burden of disease. Our primary purpose was to determine whether HAP exposure was associated with reduced lung function and respiratory and non-respiratory symptoms in Belizean adults and children. Our secondary purpose was to investigate whether lifestyle (physical activity (PA and fruit and vegetable consumption (FV is associated with reported symptoms. Belizean adults (n = 67, 19 Male and children (n = 23, 6 Male from San Ignacio Belize and surrounding areas participated in this cross-sectional study. Data collection took place at free walk-in clinics. Investigators performed initial screenings and administered questionnaires on (1 sources of HAP exposure; (2 reported respiratory and non-respiratory symptoms and (3 validated lifestyle questionnaires. Participants then performed pulmonary function tests (PFTs and exhaled breath carbon monoxide (CO. There were no significant associations between HAP exposure and pulmonary function in adults. Increased exhaled CO was associated with a significantly lower forced expiratory volume in 1-s divided by forced vital capacity (FEV1/FVC in children. Exposed adults experienced headaches, burning eyes, wheezing and phlegm production more frequently than unexposed adults. Adults who met PA guidelines were less likely to experience tightness and pressure in the chest compared to those not meeting guidelines. In conclusion, adults exposed to HAP experienced greater respiratory and non-respiratory symptoms, which may be attenuated by lifestyle modifications.

    Full Text Available Abstract Introduction Respiratory failure may develop during the later stages of pregnancy and is usually associated with tocolysis or other co-existing conditions such as pneumonia, sepsis, pre-eclampsia or amniotic fluid embolism syndrome. Case presentation We present the case of a 34-year-old healthy woman with a twin pregnancy at 31 weeks and 6 days who experienced acute respiratory failure, a few hours after administration of tocolysis (ritodrine, due to preterm premature rupture of the membranes. Her chest discomfort was significantly ameliorated after the ritodrine infusion was stopped and a Cesarean section was performed 48 hours later under spinal anesthesia; however, 2 hours after surgery she developed severe hypoxemia, hypotension, fever and mild coagulopathy. The patient was intubated and transferred to the intensive care unit where she made a quick and uneventful recovery within 3 days. As there was no evidence for drug- or infection-related thromboembolic or myocardial causes of respiratory failure, we conclude that our patient experienced a rare type of non-fatal amniotic fluid embolism. Conclusion In spite of the lack of solid scientific support for our diagnosis, we conclude that our patient suffered an uncommon type of amniotic fluid embolism syndrome and we believe that this report highlights the need for extreme vigilance and a high index of suspicion for such a diagnosis in any pregnant individual.

    Objective: To analyze effect of Naloxone combined with noninvasive positive pressure ventilation therapy on blood gas indexes and serum indexes of COPD complicated with respiratory failure patients. Methods: 116 cases of COPD complicated with respiratory failure patients treated in our hospital from June 2012 to June 2014 were enrolled and randomly divided into observation group (58 cases) who received Naloxone combined with noninvasive positive pressure ventilation therapy, and control group (58 cases) who received plain noninvasive positive pressure ventilation therapy. Then differences of blood gas indexes, serum inflammatory factor levels and serum prognosis-related factor levels of both groups were compared. Results: 1) after treatment, artery blood PaO2 and PH level of observation group were higher than those of control group; PaCO2 level was lower than that of control group (P<0.05); 2) after treatment, serum factor levels of IL-13, IL-18, sICAM-1, PGE2 and hs-CRP, etc of observation group were all significantly lower than those of control group (P<0.05); 3) after treatment, serum α1-AT, D-Dimer and BNP levels of observation group were lower than those of control group; FT3 level was higher than that of control group (P<0.05). Conclusion:Naloxone combined with noninvasive positive pressure ventilation therapy helps to improve ventilation and oxygenation levels of COPD complicated with respiratory failure patients, reduce systemic inflammatory response and optimize prognosis-related indexes.

    The plant homeodomain (PHD) finger is identified in many chromatin-binding proteins,and functions as a ‘reader' that recognizes specific epigenetic marks on histone tails,bridging transcription factors and their associated complexes to chromatin,and regulating gene expression.PHD finger-containing proteins perform many biological functions and are involved in many human diseases including cancer.PHF14 is predicted to code for a protein with multiple PHD fingers.However,its function is unidentified.The aim of this study is to characterize PHF14 and investigate its biological significance by employing multiple approaches including mouse gene-targeting knockout,and molecular cloning and characterization.Three transcripts of PHF14 in human cell lines were identified by reverse transcriptase polymerase chain reaction.Two isoforms of PHF14 (PHF14α and PHF14β) were cloned in this study.It was found that PHF14 was ubiquitously expressed in mouse tissues and human cell lines.PHF14α,the major isoform of PHF14,was localized in the nucleus and also bound to chromatin during cell division.Interestingly,co-immunoprecipitation results suggested that PHF14α bound to histones via its PHD fingers.Strikingly,genetargeting knockout of PHF14 in mice resulted in a neonatal lethality due to respiratory failure.Pathological analysis revealed severe disorders of tissue and cell structures in multiple organs,particularly in the lungs.These results indicated that PHF14 might be an epigenetic regulator and play an important role in the development of multiple organs in mouse.

    Recent advances in our understanding of neonatal pulmonary circulation and the underlying pathophysiology of hypoxemic respiratory failure (HRF)/persistent pulmonary hypertension of the newborn (PPHN) have resulted in more effective management strategies. Results from animal studies demonstrate that low alveolar oxygen tension (PAO2) causes hypoxic pulmonary vasoconstriction, whereas an increase in oxygen tension to normoxic levels (preductal arterial partial pressure of oxygen (PaO2) between 60 and 80 mm Hg and/or preductal peripheral capillary oxygen saturation between 90% and 97%) results in effective pulmonary vasodilation. Hyperoxia (preductal PaO2 >80 mm Hg) does not cause further pulmonary vasodilation, and oxygen toxicity may occur when high concentrations of inspired oxygen are used. It is therefore important to avoid both hypoxemia and hyperoxemia in the management of PPHN. In addition to oxygen supplementation, therapeutic strategies used to manage HRF/PPHN in term and late preterm neonates may include lung recruitment with optimal mean airway pressure and surfactant, inhaled and intravenous vasodilators and 'inodilators'. Clinical evidence suggests that administration of surfactant or inhaled nitric oxide (iNO) therapy at a lower acuity of illness can decrease the risk of extracorporeal membrane oxygenation/death, progression of HRF and duration of hospital stay. Milrinone may be beneficial as an inodilator and may have specific benefits following prolonged exposure to iNO plus oxygen owing to inhibition of phosphodiesterase (PDE)-3A. Additionally, sildenafil, and, in selected cases, hydrocortisone may be appropriate options after hyperoxia and oxidative stress owing to their effects on PDE-5 activity and expression. Continued investigation into these and other interventions is needed to optimize treatment and improve outcomes.

    Abstract Background: Endotracheal intubation and prolonged immobilization of patients receiving mechanical ventilation may reduce expectoration function. High-frequency chest wall oscillation (HFCWO) may ameliorate airway secretion movement; however, the instantaneous changes in patients’ cardiopulmonary responses are unknown. Moreover, HFCWO may influence ventilator settings by the vigorous oscillation. The aim of this study was to investigate these issues. Methods: Seventy-three patients (52 men) aged 71.5 ± 13.4 years who were intubated with mechanical ventilation for pneumonic respiratory failure were recruited and randomly classified into 2 groups (HFCWO group, n = 36; and control group who received conventional chest physical therapy (CCPT, n = 37). HFCWO was applied with a fixed protocol, whereas CCPT was conducted using standard protocols. Both groups received sputum suction after the procedure. Changes in ventilator settings and the subjects’ responses were measured at preset intervals and compared within groups and between groups. Results: Oscillation did not affect the ventilator settings (all P > 0.05). The mean airway pressure, breathing frequency, and rapid shallow breathing index increased, and the tidal volume and SpO2 decreased (all P < 0.05). After sputum suction, the peak airway pressure (Ppeak) and minute ventilation decreased (all P < 0.05). The HFCWO group had a lower tidal volume and SpO2 at the end of oscillation, and lower Ppeak and tidal volume after sputum suction than the CCPT group. Conclusions: HFCWO affects breathing pattern and SpO2 but not ventilator settings, whereas CCPT maintains a steadier condition. After sputum suction, HFCWO slightly improved Ppeak compared to CCPT, suggesting that the study extends the indications of HFCWO for these patients in intensive care unit.

    Full Text Available There is much interest in the mechanisms that regulate adult tissue homeostasis and their relationship to processes governing foetal development. Mice deleted for the Wilms' tumour gene, Wt1, lack kidneys, gonads, and spleen and die at mid-gestation due to defective coronary vasculature. Wt1 is vital for maintaining the mesenchymal-epithelial balance in these tissues and is required for the epithelial-to-mesenchyme transition (EMT that generates coronary vascular progenitors. Although Wt1 is only expressed in rare cell populations in adults including glomerular podocytes, 1% of bone marrow cells, and mesothelium, we hypothesised that this might be important for homeostasis of adult tissues; hence, we deleted the gene ubiquitously in young and adult mice. Within just a few days, the mice suffered glomerulosclerosis, atrophy of the exocrine pancreas and spleen, severe reduction in bone and fat, and failure of erythropoiesis. FACS and culture experiments showed that Wt1 has an intrinsic role in both haematopoietic and mesenchymal stem cell lineages and suggest that defects within these contribute to the phenotypes we observe. We propose that glomerulosclerosis arises in part through down regulation of nephrin, a known Wt1 target gene. Protein profiling in mutant serum showed that there was no systemic inflammatory or nutritional response in the mutant mice. However, there was a dramatic reduction in circulating IGF-1 levels, which is likely to contribute to the bone and fat phenotypes. The reduction of IGF-1 did not result from a decrease in circulating GH, and there is no apparent pathology of the pituitary and adrenal glands. These findings 1 suggest that Wt1 is a major regulator of the homeostasis of some adult tissues, through both local and systemic actions; 2 highlight the differences between foetal and adult tissue regulation; 3 point to the importance of adult mesenchyme in tissue turnover.

    Background Early withdraw from invasive mechanical ventilation (MV) followed by noninvasive MV is a new strategy for changing modes of treatment. This study was conducted to estimate the feasibility and the efficacy of early extubation and sequential noninvasive MV commenced at beginning of pulmonary infection control window in patients with exacerbated hypercapnic respiratory failure caused by chronic obstructive pulmonary diseases (COPD). Methods A prospective, randomized controlled study was conducted in eleven teaching hospitals' respiratory or medical intensive care units in China. Ninety intubated COPD patients with severe hypercapnic respiratory failure triggered by pulmonary infection (pneumonia or purulent bronchitis) were involved in the study. When the pulmonary infection had been controlled by antibiotics and comprehensive therapy, the "pulmonary infection control window (PIC window)" has been reached. Each case was randomly assigned to study group (extubation and noninvasive MV via facial mask immediately) or control group (invasive MV was received continuously after PIC window by using conventional weaning technique).Results Study group (n=47) and control group (n=43) had similar clinical characteristics initially and at the time of PIC window. Compared with control group, study group had shorter duration of invasive MV [(6.4±4.4) days vs (11.3±6.2) days, P=0.000], lower rate of ventilator associated pneumonia (VAP) (3/47 vs 12/43, P=0.014), fewer days in ICU [(12±8) days vs (16±11) days, P=0.047] and lower hospital mortality (1/47 vs 7/43, P=0.025).Conclusions In COPD patients requiring intubation and invasive MV for hypercapnic respiratory failure, which is exacerbated by pulmonary infection, early extubation followed by noninvasive MV initiated at the start of PIC window may decrease significantly the duration of invasive MV, the risk of VAP and hospital mortality.

We assessed the factors associated with failure of NIMV in patients with ARF and severe acidosis admitted to the emergency department and followed on respiratory ward.Patients and methods: This is a retrospective observational cohort study conducted in a tertiary teaching hospital specialized in chest diseases and thoracic surgery between June 1, 2013 and May 31, 2014. COPD patients who were admitted to our emergency department due to ARF were included. Patients were grouped according to the severity of acidosis into two groups: group 1 (pH=7.20–7.25 and group 2 (pH=7.26–7.30.Results: Group 1 included 59 patients (mean age: 70±10 years, 30.5% female and group 2 included 171 patients (mean age: 67±11 years, 28.7% female. On multivariable analysis, partial arterial oxygen pressure to the inspired fractionated oxygen (PaO2/FiO2 ratio <200, delta pH value <0.30, and pH value <7.31 on control arterial blood gas after NIMV in the emergency room and peak C-reactive protein were found to be the risk factors for NIMV failure in COPD patients with ARF in the ward.Conclusion: NIMV is effective not only in mild respiratory failure but also with severe forms of COPD patients presenting with severe exacerbation. The determination of the failure criteria of NIMV and the expertise of the team is critical for treatment success. Keywords: noninvasive mechanical ventilation

    Obesity is both a risk factor and a direct cause of heart failure (HF) in adults. Severe obesity produces hemodynamic alterations that predispose to changes in left ventricular morphology and function, which, over time, may lend to the development of HF (obesity cardiomyopathy). Certain neurohormonal and metabolic abnormalities as well as cardiovascular co-morbidities may facilitate this process. Substantial purposeful weight loss is capable of reversing most of the alterations in cardiac performance and morphology and may improve functional capacity and quality of life in patents with obesity cardiomyopathy.

    Objective:To observe the efficacy of non-invasive positive pressure ventilation (NIPPV) in the treatment of respiratory failure in patients with COPD at the acute exacerbation stage. Methods:A total of 38 COPD patients at the acute exacerbation stage with respiratory failure who were admitted in our hospital from January, 2012 to January, 2013 with complete medical materials were included in the study and divided into the observation group and the control group according to different treatment methods. On admission, the patients in the two groups were given oxygen inhalation, positive infection control, and drugs that could improve the respiratory function. On the basis, the patients in the observation group were given additional NIPPV. The improvement of blood gas indicators 4, 24, 72 d after admission, and 5, 30 d after discharge in the two groups was compared. The hospitalization time and the number of second hospitalization within 3 months in the two groups were compared.Results: In the observation group, pH value after 4 h ventilation was significantly elevated, and maintained at a stable state after 24 h ventilation, while in the control group, the change of pH value was not statistically significant, and after 5 d treatment, pH value was yet low. In the observation group, PaCO2 was significantly reduced in a short ventilation time, while in the control group, the descending range was small. The comparison of pH and PaCO2 4 h, 24 h, 72 h, and 5 d after treatment between the two groups was statistically significant, but PaCO2 in the two groups could not reduce to the normal level. PaO2 after treatment in the two groups was improved, but the improved degree in the observation degree was significantly superior to that in the control group. The comparison of blood gas indicators 30 d after discharge between the two groups was not statistically significant. The hospitalization time in the observation group was shortened, and the number of second hospitalization

    We report a unique utilization of a double-lumen, bi-caval Avalon cannula for veno-venous (VV) extracorporeal membrane oxygenation (ECMO) during placement of a total artificial heart (TAH, SynCardia, Tucson, AZ). A 22-year-old female with post-partum cardiomyopathy was rescued on veno-arterial (VA) ECMO because of cardiogenic shock. The inability to wean ECMO necessitated implantation of the TAH as a bridge to transplant. In addition, the patient continued to have respiratory failure and concomitant VV ECMO was planned with the implant. During TAH implantation, the Avalon cannula was placed percutaneously from the right internal jugular vein into the inferior vena cava (IVC) under direct vision while the right atrium was open. During VV ECMO support, adequate flows on both ECMO and TAH were maintained without adverse events. VV ECMO was discontinued, without reopening the chest, once the patient's respiratory failure improved. However, the patient subsequently developed a profound respiratory acidosis and required VV ECMO for CO2 removal. The Avalon cannula was placed in the femoral vein to avoid accessing the internal jugular vein and risking damage to the TAH. The patient's oxygenation eventually improved and the cannula was removed at the bedside. The patient was supported for 22 days on VV ECMO and successfully weaned from the ventilator prior to her orthotropic heart transplantation.

    Full Text Available Abstract Background Human bocavirus (HBoV is a newly discovered parvovirus associated with acute respiratory tract illness (ARTI and gastrointestinal illness. Our study is the first to analyze the characteristics of HBoV-positive samples from ARTI patients with a wide age distribution from Guangzhou, southern China. Methods Throat swabs (n=2811 were collected and analyzed from children and adults with ARTI over a 13-month period. The HBoV complete genome from a 60 year-old female patient isolate was also determined. Results HBoV DNA was detected in 65/2811 (2.3% samples, of which 61/1797 were from children (Mycoplasma pneumoniae had the highest frequency of 16.9% (11/65. Upper and lower respiratory tract illness were common symptoms, with 19/65 (29.2% patients diagnosed with pneumonia by chest radiography. All four adult patients had systemic influenza-like symptoms. Phylogenetic analysis of the complete genome revealed a close relationship with other HBoVs, and a more distant relationship with HBoV2 and HBoV3. Conclusions HBoV was detected from children and adults with ARTI from Guangzhou, southern China. Elderly people were also susceptive to HBoV. A single lineage of HBoV was detected among a wide age distribution of patients with ARTI.

    We report two children who survived neurologic injury (near-drowning and Reye's syndrome) and adult respiratory distress syndrome and who required prolonged ventilatory support. Follow-up examination in both children showed steady neurologic recovery, but five months following discharge from their acute illness, profound hearing loss was diagnosed in both children. A review of the literature is reported and the hypothesis that combined aminoglycoside antibiotic and loop diuretic therapy caused the hearing loss is presented. Recommendation is made for audiologic assessment within six months of recovery from critical illness of pediatric patients in whom therapy has included loop diuretic and aminoglycoside antibiotic therapy.

    Full Text Available Introduction: The majority of Indian hospitals do not provide intensive care unit (ICU care or ward-based noninvasive positive pressure ventilation (NIV. Because no mechanical ventilation or NIV is available in these hospitals, the majority of patients suffering from respiratory failure die. Objective: To perform a cost-effective analysis of two strategies (ward-based NIV with concurrent standard treatment vs standard treatment alone in chronic obstructive pulmonary disease (COPD respiratory failure patients treated in Indian hospitals without ICU care. Materials and Methods: A decision-analytical model was created to compare the cost-effectiveness for the two strategies. Estimates from the literature were used for parameters in the model. Future costs were discounted at 3%. All costs were reported in USD (2012. One-way, two-way, and probabilistic sensitivity analysis were performed. The time horizon was lifetime and perspective was societal. Results: The NIV strategy resulted in 17.7% more survival and was slightly more costly (increased cost of $101 (USD 2012 but resulted in increased quality-adjusted life-years (QALYs (1.67 QALY. The cost-effectiveness (2012 USD/QALY in the standard and NIV groups was $78/QALY ($535.02/6.82 and $75/QALY ($636.33/8.49, respectively. Incremental cost-effectiveness ratio (ICER was only $61 USD/QALY. This was substantially lower than the gross domestic product (GDP per capita for India (1489 USD, suggesting the NIV strategy was very cost effective. Using a 5% discount rate resulted in only minimally different results. Probabilistic analysis suggests that NIV strategy was preferred 100% of the time when willingness to pay was >$250 2012 USD. Conclusion: Ward-based NIV treatment is cost-effective in India, and may increase survival of patients with COPD respiratory failure when ICU is not available.

  18. Usefulness of clinical data and rapid diagnostic tests to identify bacterial etiology in adult respiratory infections

    Full Text Available Respiratory tract infections are a common complaint and most of them, such as common cold and laryngitis, are viral in origin, so antibiotic use should be exceptional. However, there are other respiratory tract infections (sinusitis, pharyngitis, lower respiratory tract infections, and exacerbations of chronic obstructive pulmonary disease where a bacterial etiology is responsible for a non-negligible percentage, and antibiotics are often empirically indicated. The aim of the study is to identify the strength of the data obtained from the symptoms, physical examination and rapid diagnostic methods in respiratory infections in which antibiotic use is frequently proposed in order to improve diagnosis and influence the decision to prescribe these drugs. The review concludes that history, physical examination and rapid tests are useful to guide the need for antibiotic treatment in diseases such as acute sinusitis, acute pharyngitis, exacerbation of lower respiratory tract infection and chronic obstructive pulmonary disease. However, no isolated data is accurate enough by itself to confirm or rule out the need for antibiotics. Therefore, clinical prediction rules bring together history and physical examination, thereby improving the accuracy of the decision to indicate or not antibiotics.

    microRNAs (miRNAs) belong to a class of non-coding RNAs that regulate post-transcriptional gene expression during development and disease. Growing evidence indicates abundant miRNA expression changes and their important role in cardiac hypertrophy and failure. However, the role of miRNAs in fetal cardiac remodeling is little known. Here, we investigated the altered expression of fifteen miRNAs in rat fetal cardiac remodeling compared with adult cardiac remodeling. Among fifteen tested miRNAs, eleven and five miRNAs (miR-199a-5p, miR-214-3p, miR-155-3p, miR-155-5p and miR-499-5p) are significantly differentially expressed in fetal and adult cardiac remodeling, respectively. After comparison of miRNA expression in fetal and adult cardiac remodeling, we find that miRNA expression returns to the fetal level in adult cardiac failure and is activated in advance of the adult level in fetal failure. The current study highlights the contrary expression pattern between fetal and adult cardiac remodeling and that supports a novel potential therapeutic approach to treating heart failure.

    Human rhinovirus (HRV) is an important causative agent of acute respiratory tract infections (ARTIs). The roles of specific HRV genotypes in patients suffering from ARTIs have not been well established. We recruited 147 adult inpatients with community-acquired pneumonia (CAP) and 291 adult outpatients with upper ARTIs (URTIs). Respiratory pathogens were screened via PCR assays. HRV was detected in 42 patients, with 35 species A, five B and two C. Seventeen genotypes were identified, and HRV-A21 ranked the highest (9/42, 21.4%). The HRV-A21-positive infections were detected in four patients with CAP and in five with URTIs, all without co-infections. The HRV-A21 genome sequenced in this study contained 12 novel coding polymorphisms in viral protein (VP) 1, VP2 EF loop, VP3 knob and 3D regions. The infections of HRV-A21 virus obtained in this study could not be neutralized by antiserum of HRV-A21 prototype strain (VR-1131), indicating remarkable antigenic variation. Metagenomic analysis showed the HRV-A21 reads were dominant in bronchoalveolar lavage fluid of the three HRV-A21-positive patients with severe CAP, in which two dead. Our results highlight an unexpected infection of genotype HRV-A21 in the clinic, indicating the necessity of precise genotyping and surveillance of HRVs to improve the clinical management of ARTIs.

    The aim of the present study was to specifically investigate the involvement of serotonin [5-hydroxytryptamine (5-HT(2))] receptors in 5-HT-mediated respiratory recovery after cervical hemisection. Experiments were conducted on C(2) spinal cord-hemisected, anesthetized (chloral hydrate, 400 mg/kg ip), vagotomized, pancuronium- paralyzed, and artificially ventilated female Sprague-Dawley rats in which CO(2) levels were monitored and maintained. Twenty-four hours after spinal hemisection, the ipsilateral phrenic nerve displayed no respiratory-related activity indicative of a functionally complete hemisection. Intravenous administration of the 5-HT(2A/2C)-receptor agonist (+/-)-2,5-dimethoxy-4-iodoamphetamine hydrochloride (DOI) induced respiratory-related activity in the phrenic nerve ipsilateral to hemisection under conditions in which CO(2) was maintained at constant levels and augmented the activity induced under conditions of hypercapnia. The effects of DOI were found to be dose dependent, and the recovery of activity could be maintained for up to 2 h after a single injection. DOI-induced recovery was attenuated by the 5-HT(2)-receptor antagonist ketanserin but not with the 5-HT(2C)-receptor antagonist RS-102221, suggesting that 5-HT(2A) and not necessarily 5-HT(2C) receptors may be involved in the induction of respiratory recovery after cervical spinal cord injury.

    Heart failure (HF) is the leading cause of death in adults with repaired congenital heart disease (CHD). However there is currently little evidence to guide treatment strategies in this growing group of patients. Unlike the majority of HF, which is usually caused by LV systolic or diastolic dysfunction, CHD-HF is more often a consequence of RV disease, valve dysfunction, shunting or pulmonary hypertension. It is therefore not appropriate to extrapolate from the acquired HF literature and apply it to this heterogeneous population of CHD patients. Additionally, patients with CHD have been excluded from most large trials of medical or device therapy of HF, which has resulted in small retrospective and underpowered studies in the CHD population. This article critically reviews the current knowledge about CHD-HF, paying particular attention to medical therapy in different CHD populations, cardiac resynchronisation therapy and implantable cardiac defibrillators, and the challenges of heart transplantation and mechanical circulatory support in CHD patients.

    The goal of therapy for older adults who have type 2 diabetes and pancreatic failure is to provide the best management program that meets his/her individual needs and lifestyle. The goals are to maintain blood sugar control, but more importantly, to prevent complications and to provide the patient with a better quality of life through a more natural metabolic state. Decisions about when to add insulin to the regimen, the goals of therapy, what types of insulin to use, and how to monitor response are based on the pathophysiologic mechanisms, which ensures overall treatment success. The information that patients gather and record will assist in decisions about therapy that maximize the benefits and eliminate the problems that patients often experience when therapies are modified without a careful plan.

    2005-04-01

    Full Text Available Abstract Background It has been postulated that genetic predisposition may influence the susceptibility to SARS-coronavirus infection and disease outcomes. A recent study has suggested that the deletion allele (D allele of the angiotensin converting enzyme (ACE gene is associated with hypoxemia in SARS patients. Moreover, the ACE D allele has been shown to be more prevalent in patients suffering from adult respiratory distress syndrome (ARDS in a previous study. Thus, we have investigated the association between ACE insertion/deletion (I/D polymorphism and the progression to ARDS or requirement of intensive care in SARS patients. Method One hundred and forty genetically unrelated Chinese SARS patients and 326 healthy volunteers were recruited. The ACE I/D genotypes were determined by polymerase chain reaction and agarose gel electrophoresis. Results There is no significant difference in the genotypic distributions and the allelic frequencies of the ACE I/D polymorphism between the SARS patients and the healthy control subjects. Moreover, there is also no evidence that ACE I/D polymorphism is associated with the progression to ARDS or the requirement of intensive care in the SARS patients. In multivariate logistic analysis, age is the only factor associated with the development of ARDS while age and male sex are independent factors associated with the requirement of intensive care. Conclusion The ACE I/D polymorphism is not directly related to increased susceptibility to SARS-coronavirus infection and is not associated with poor outcomes after SARS-coronavirus infection.

    Medication reconciliation problems are common among older adults at hospital discharge and lead to adverse events. The purpose of this study was to examine the rates and types of medication reconciliation problems among older adults hospitalized for acute episodes of heart failure who were discharged home. This secondary analysis of data generated from a transitional care intervention included 198 hospital discharge medical records, representing 162 patients. A retrospective chart review comparing medication lists between hospital discharge summaries and patient discharge instructions was completed to identify medication reconciliation problems. Most hospital discharges (71.2%) had at least one type of reconciliation problem and frequently involved a high-risk medication (76.6%). Discrepancies were the most common problem (58.9%), followed by incomplete discharge summaries (52.5%) and partial patient discharge instructions (48.9%). More attention needs to be given to the quality of discharge instructions, and the problem of vague phrases (e.g., "take as directed") can be addressed by adding it to "do not use" lists to promote safer transitions in care.

    Full Text Available Few investigators have studied cognition over time in adults with heart failure (HF. A battery of neuropsychological tests was administered to 279 adults with chronic systolic or diastolic HF at baseline, three and six months. Growth mixture modeling (GMM was used to model the measure anticipated to be most sensitive, the digit symbol substitution task (DSST. We describe how and why the DSST patterns change over time. Other measures of cognition were examined to identify consistency with the DSST patterns. The sample was predominantly male (63.2%, Caucasian (62.7%, mean age 62 years. The best fit GMM revealed two trajectories of DSST scores: Average processing speed group (40.5% and Below Average processing speed (59.9%. Neither group changed significantly over the six month study. Other measures of cognition were consistent with the DSST patterns. Factors significantly associated with increased odds of being in the Below Average processing speed group included older age, male gender, Non-Caucasian race, less education, higher ejection fraction, high comorbid burden, excessive daytime sleepiness, and higher BMI. As some of the factors related to cognitive impairment are modifiable, research is needed to identify interventions to preserve and improve cognition in these patients.

    Acute respiratory distress syndrome is a disease of acute onset characterized by hypoxemia and infiltrates on chest radiographs that affects both adults and children of all ages. It is an important cause of respiratory failure in pediatric intensive care units and is associated with significant morbidity and mortality. Nevertheless, until recently, the definitions and diagnostic criteria for acute respiratory distress syndrome have focused on the adult population. In this article, we review the evolution of the definition of acute respiratory distress syndrome over nearly five decades, with a special focus on the new pediatric definition. We also discuss recommendations for the implementation of mechanical ventilation strategies in the treatment of acute respiratory distress syndrome in children and the use of adjuvant therapies.

    Full Text Available Abstract Background Measuring the state of health is a method for quantifying the impact of an illness on the day-to-day life, health and wellbeing of a patient, providing a quantitative measure of an individual’s quality of life (QoL. QoL expresses patient point of view by a subjective dimension and can express the results of medical intervention. Pulmonary rehabilitation is an essential component in the management of COPD patients, and measuring QoL has become a central focus in the study of this disease. Although nowadays several questionnaires for measuring the QoL in COPD patients are available, there are no questionnaires specifically developed for evaluating QoL in COPD patients undergoing respiratory rehabilitation. The aim of this study was to develop a novel questionnaire for the QoL quantification in COPD patients undergoing in-patient pulmonary rehabilitation program. Methods The questionnaire, administered to COPD patients undergoing long-term oxygen therapy into a respiratory rehabilitation ward, was developed by a simple and graphic layout to be administered to elderly patients. It included one form for admission and another for discharge. It included only tips related to the subjective components of QoL that would be relevant for patient, although likely not strictly related to the respiratory function. A descriptive analysis was performed for the socio-demographic characteristics and both the non-parametric Wilcoxon T-test and the Cronbach’s alpha index were calculated for evaluating the sensitivity of the questionnaire to the effects of respiratory rehabilitation and for identifying its consistency. Results The physical and psychological condition of the 34 COPD patients improved after the rehabilitative treatment and this finding was detected by the questionnaire (overall improvement: 14.2±2.5%, as confirmed by the non-parametric Wilcoxon test (p Conclusions This proposed questionnaire represents a substantial innovation

    To assess associations between acculturation, depression, and self-reported stress score with reported diagnosis of respiratory disease (RD) in Puerto Rican adults, participants (N = 1,168) were identified from areas of high Hispanic density in the Boston, MA metropolitan area. Eligible participants were interviewed in the home by bilingual interviewers in either Spanish or English. Scales included topics ranging from general background to depressive symptomatology. Respiratory disease was self-reported and checked against prescribed medication. More than one-third (37.8%) of subjects reported doctor-diagnosed RD. A final binary logistical regression model (N = 850), which was adjusted for potential confounders (sex, age, education, poverty) showed that RD was significantly associated with psychological acculturation (OR = 1.97, P = 0.005), depressive symptomatology (OR = 1.52, P = 0.03) high perceived stress score (OR = 1.97, P = 0.009), and current smoking (OR = 1.61, P = 0.03). Significant inverse associations included a high level of language acculturation (OR = 0.65, P = 0.03), light (OR = 0.67, P = 0.01) and moderate to heavy physical activity versus sedentary physical activity (OR = 0.40, P = 0.03). We found self reported physician diagnosed RD was associated with high perceived stress and depression, as well as higher levels of psychological acculturation. Longitudinal research is needed to determine if there is a causal pathway for these associations.

    As the population of adults with congenital heart disease continues to grow, so does the number of these patients with heart failure. Ventricular assist devices are underutilized in adults with congenital heart disease due to their complex anatomic arrangements and physiology. Advanced imaging techniques that may increase the utilization of mechanical circulatory support in this population must be explored. Three-dimensional printing offers individualized structural models that would enable pre-surgical planning of cannula and device placement in adults with congenital cardiac disease and heart failure who are candidates for such therapies. We present a review of relevant cardiac anomalies, cases in which such models could be utilized, and some background on the cost and procedure associated with this process.

    The role of Serratia marcescens changed from a harmless saprophytic microorganism to an important opportunistic human pathogen. It often causes nosocomial device-associated outbreaks and rarely serious invasive community acquired infections. We present a case of a community-acquired Serratia marcescens bacteremia leading to Respiratory Distress Syndrome in a previously healthy 51-year-old man without identifiable risk factors. Full recovery was achieved with solely medical treatment and observation in ICU during three days. To our knowledge it is an extremely uncommon presentation and just few cases have been previously reported in the literature.

    Early liver transplant (LT) has been advocated for patients with cystic fibrosis liver disease (CFLD) and evidence of deterioration in nutritional state and respiratory function to prevent further decline. However, the impact of single LT on long-term respiratory function and nutritional status has not been adequately addressed. We performed a retrospective analysis of the outcomes of 40 (21 adult/19 pediatric) patients with CFLD transplanted between 1987 and 2009 with median follow-up of 47.8 months (range 4-180). One and five-year actuarial survival rates were 85%/64% for adult and 90%/85% for pediatric LT cohorts, respectively. Lung function remained stable until 4 years (FEV(1) % predicted; pretransplant 48.4% vs. 45.9%, 4 years posttransplant) but declined by 5 years (42.4%). Up to 4 years posttransplant mean annual decline in FEV(1) % was lower (0.74%; p = 0.04) compared with the predicted 3% annual decline in CF patients with comorbidity including diabetes. Number of courses of intravenous antibiotics was reduced following LT, from 3.9/year pretransplant to 1.1/year, 5 years posttransplant. Body mass index was preserved posttransplant; 18.0 kg/m(2) (range 15-24.3) pretransplant versus 19.6 kg/m(2) (range 16.4-22.7) 5 years posttransplant. In conclusion, LT is an effective treatment for selected patients with cirrhosis due to CFLD, stabilizing aspects of long-term lung function and preserving nutritional status.

    Importance Stem cell therapy is a promising treatment strategy for patients with heart failure, which accounts for over 10% of deaths in the U.S. annually. Despite over a decade of research, further investigation is still needed to determine whether stem cell regenerative therapy is clinically effective and can be routinely implemented in clinical practice. Objective The purpose of this review is to describe the current progress in cardiac stem cell regenerative therapy using adult stem cells and highlight the merits and limitations of clinical trials performed to date. Evidence Review Information for this review was obtained through a search of PubMed and the Cochrane database for English language studies published between January 1, 2000 and April 20, 2016. Twenty-nine randomized clinical trials and 7 systematic reviews and meta-analyses were included in this review. Findings Although adult stem cells were once believed to have the ability to create new heart tissue or grow blood vessels, preclinical studies suggest instead that these cells release cardio-protective paracrine factors that activate endogenous pathways, leading to myocardial repair. Subsequent randomized controlled clinical trials, the majority of which used autologous bone marrow mononuclear cells, have found only a modest benefit in patients receiving stem cell therapy. The lack of a significant benefit may result from variations in trial methodology, discrepancies in reporting, and an over-reliance on surrogate endpoints. Conclusions and Relevance Although stem cell therapy for cardiovascular disease is not yet ready for routine clinical application, significant progress continues to be made. Physicians should be aware of the current status of this treatment so that they can better inform their patients who may be in search of alternative therapies. PMID:27557438

    Acute respiratory distress syndrome (ARDS) caused by pneumonia in patients with hematologic malignancies can be life-threatening. Extracorporeal membrane oxygenation (ECMO) is the only temporary treatment for patients with ARDS who are refractory to conventional treatment. However, the immunosuppression and coagulopathies in hematological malignancies such as lymphoma and acute leukemia are relative contraindications for ECMO, due to high risks of infection and bleeding. Here, we report a 22-year-old man with acute myeloid leukemia (AML) who developed pneumonia and ARDS during induction chemotherapy; he was treated with ECMO. PMID:28275497

    2011-07-01

    Full Text Available Lobar fiberoptic lung lavage is a well-known procedure used in primary pulmonary alveolar proteinosis (PAP; the use of this procedure has increased in the recent years. This procedure has also been used in other pulmonary diseases such as desquamative interstitial pneumonia with good results. We describe a case of extremely severe respiratory failure due to concurrence of PAP and Influenza A H1N1 virus pneumonia which resolved with the help of this procedure. The patient, a 41- year-old woman, needed less mechanical ventilation after undergoing lobar fiberoptic bronchoscopic lavage. Moreover, a rapid and progressive improvement in the computed tomography of the lungs was observed. Flexibile fiberoptic bronchoscopic lobar lavage is a simple, safe procedure used not only in milder disease, but also in particular severe cases in which the physiological derangement of whole lung lavage would not be tolerated by patient or when extra-corporeal membrane oxygenation is not available.

    2012-10-01

    Full Text Available Background: Cerebral hypoperfusion accompanies heart failure (HF and is associated with reduced cognitive performance. Obesity is prevalent in persons with HF and is also a likely contributor to cognitive function, as it has been independently linked to cognitive impairment in healthy individuals. The current study examined the association between obesity and cognitive performance among older adults with HF and whether obesity interacts with cerebral hypoperfusion to exacerbate cognitive impairment. Methods: Patients with HF (n = 99, 67.46 ± 11.36 years of age completed neuropsychological testing and impedance cardiography. Cerebral blood flow velocity (CBF-V measured by transcranial Doppler sonography quantified cerebral perfusion and body mass index (BMI operationalized obesity. Results: A hierarchical regression analysis showed that lower CBF-V was associated with reduced performance on tests of attention/executive function and memory. Elevated BMI was independently associated with reduced attention/executive function and language test performance. Notably, a significant interaction between CBF-V and BMI indicated that a combination of hypoperfusion and high BMI has an especially adverse influence on attention/executive function in HF patients. Conclusions: The current findings suggest that cerebral hypoperfusion and obesity interact to impair cognitive performance in persons with HF. These results may have important clinical implications, as HF patients who are at high risk for cerebral hypoperfusion may benefit from weight reduction.

    Blood flow requirements of the respiratory muscles (RM) increase markedly during exercise in chronic heart failure (CHF). We reasoned that if the RM could subtract a fraction of the limited cardiac output (QT) from the peripheral muscles, RM unloading would improve locomotor muscle perfusion. Nine patients with CHF (left ventricle ejection fraction = 26 +/- 7%) undertook constant-work rate tests (70-80% peak) receiving proportional assisted ventilation (PAV) or sham ventilation. Relative changes (Delta%) in deoxy-hemoglobyn, oxi-Hb ([O2Hb]), tissue oxygenation index, and total Hb ([HbTOT], an index of local blood volume) in the vastus lateralis were measured by near infrared spectroscopy. In addition, QT was monitored by impedance cardiography and arterial O2 saturation by pulse oximetry (SpO2). There were significant improvements in exercise tolerance (Tlim) with PAV. Blood lactate, leg effort/Tlim and dyspnea/Tlim were lower with PAV compared with sham ventilation (P 0.05). Unloaded breathing, however, was related to enhanced leg muscle oxygenation and local blood volume compared with sham, i.e., higher Delta[O2Hb]% and Delta[HbTOT]%, respectively (P < 0.05). We conclude that RM unloading had beneficial effects on the oxygenation status and blood volume of the exercising muscles at similar systemic O2 delivery in patients with advanced CHF. These data suggest that blood flow was redistributed from respiratory to locomotor muscles during unloaded breathing.

    Cidofovir is an antiviral agent used in the therapy of recurrent respiratory papillomatosis (RRP). In this study, we hypothesized that cidofovir is effective in decreasing the viral load of human papillomavirus (HPV). We established a type specific real-time PCR and measured HPV DNA loads. The course of viral load of HPV types 6 and 11 after repeated applications of cidofovir intralesionally was compared to the clinical outcome using a modified Derkay score. In 6 of the 8 (75 %) patients, we detected HPV 6. In 2 (25 %) patients, we detected HPV 11. In all of the patients, the viral load and the modified Derkay score decreased significantly during the treatment. We conclude that viral load of HPV can be monitored using the technique described here. Cidofovir in combination with surgical debulking reduces the viral load in patients with RRP. Relapses of the symptoms cannot be avoided but might be delayed.

    Background: Application noninvasive ventilation in the patients with exacerbation of chronic obstructive pulmonary disease (COPD) reduced mortality. This case-control study was designed to compare efficiency and outcome of non-invasive (NIV) versus invasive positive pressure ventilation (IPPV) in respiratory failure due to COPD. Methods: The patients were assigned to NIV or IPPV intermittantly.The clinical parameters, including RR (respiratory rate), BP (blood pressure), HR (heart rate) and PH, PaCO2, PaO2 before and 1, 4 and 24 h after treatment were measured. Demographic information such as age, sex, severity of disease based on APACHE score, length of stay and outcome were recorded. Results: Fifty patients were enrolled in the NIV group and 50 patients in IPPV. The mean age was 70.5 in NIV and 63.9 in invasive ventilation group (p>0.05). In IPPV group, the average values of PH: PCO2: and PO2, were 7.22±0.11, 69.64 + 24.25: and 68.86±24.41 .In NIV, the respective values were 7.30±0.07, 83.94±18.95, and 60.60±19.88. In NIV group, after 1, 4 and 24 h treatment, the clinical and ventilation parameters were stable. The mean APACHE score in was IPPV, 26.46±5.45 and in NIV was 12.26±5.54 (p<0.05). The average length of hospital stay in IPPV was 15.90±10 and in NIV 8.12±6.49 days (p<0.05). The total mortality in the NIV was 4 (8%) and in IPPV, 27 patients (54%) (p<0.05). Conclusion: This study indicates that using NIPPV is a useful therapeutic mode of treatment for respiratory failure with acceptable success rate and lower mortality. The application of NIPPV reduces hospital stay, intubation and its consequent complications. PMID:27386061

    Full Text Available Abstract Background Scrub typhus, a mite-transmitted zoonosis caused by Orientia tsutsugamushi, is an endemic disease in Taiwan and may be potentially fatal if diagnosis is delayed. Case presentations We encountered a 23-year-old previously healthy Taiwanese male soldier presenting with the right ear pain after training in the jungle and an eleven-day history of intermittent high fever up to 39°C. Amoxicillin/clavulanate was prescribed for otitis media at a local clinic. Skin rash over whole body and abdominal cramping pain with watery diarrhea appeared on the sixth day of fever. He was referred due to progressive dyspnea and cough for 4 days prior to admission in our institution. On physical examination, there were cardiopulmonary distress, icteric sclera, an eschar in the right external auditory canal and bilateral basal rales. Laboratory evaluation revealed thrombocytopenia, elevation of liver function and acute renal failure. Chest x-ray revealed bilateral diffuse infiltration. Doxycycline was prescribed for scrub typhus with acute respiratory distress syndrome and multiple organ failure. Fever subsided dramatically the next day and he was discharged on day 7 with oral tetracycline for 7 days. Conclusion Scrub typhus should be considered in acutely febrile patients with multiple organ involvement, particularly if there is an eschar or a history of environmental exposure in endemic areas. Rapid and accurate diagnosis, timely administration of antibiotics and intensive supportive care are necessary to decrease mortality of serious complications of scrub typhus.

    2016-01-01

    Background: Chronic respiratory disease (CRD) causes substantial morbidity and mortality. Although the global CRD epidemic collides with the tuberculosis (TB) epidemic in many low- and middle-income country settings, the risk of TB-associated CRD is not well described in countries with a high burden of TB. Methods: We recruited 136 patients with a history of sputum smear-positive pulmonary TB (PTB) from the TB clinic at Omdurman Teaching Hospital in Khartoum, Sudan, and 136 age- and sex-matched community controls, between 28 July 2013 and 30 December 2013. Data were collected using standardised questionnaires and spirometry was performed before and after bronchodilator. Results: The mean age of the subjects with previous PTB and controls was respectively 44.0 years (SD 8.5) and 44.5 years (SD 8.6), with 27.2% females in both groups. Chronic respiratory symptoms such as chronic cough (OR 6.67, 95%CI 2.98–14.90, P grupo de los casos fue 44,0 (desviación estándar 8,5 años) y en el grupo de testigos fue 44,5 años (8,6 años); la proporción de mujeres en ambos grupos fue 27,2%. Se observó una fuerte asociación entre la presencia de síntomas respiratorios crónicos como la tos (OR 6,67; IC95% 2,98–14,90; P < 0,001) y la presencia de obstrucción crónica al flujo en las vías respiratorias (OR 12,39; IC95% 1,56–98,40; P = 0,02) en las personas con antecedente de TBP, una vez corregidos los posibles factores de confusión. Conclusión: La presencia de rasgos clínicos de EPC exhibe una fuerte correlación con el antecedente de TBP. Es preciso considerar la posibilidad de aplicar un enfoque integrado con el fin de mejorar la atención de ambas enfermedades tan frecuentes. PMID:27695684

    Full Text Available Acute respiratory distress syndrome (ARDS is a severe lung disease associated with high mortality despite recent advances in management. Significant advances in extracorporeal membrane oxygenation (ECMO devices and management allow short-term support for patients with acute reversible respiratory failure and can serve as a bridge to transplantation in patients with irreversible respiratory failure. When ARDS does not respond to conventional treatment, ECMO and the interventional lung assist membrane (iLA are the most widely used complementary treatment options. Here, we report a clinical case of an adult patient who required prolonged duration venovenous (VV-ECMO for severe ARDS resulting in improvement while waiting for lung transplantation.

    The presentation, natural history, clinical outcomes, and response to therapy in patients with heart failure differ in some ways across populations. Women, older adults, and non-Caucasian racial or ethnic groups compose a substantial proportion of the overall heart failure population, but they have typically been underrepresented in clinical trials. As a result, uncertainty exists about the efficacy of some guideline-directed medical therapies and devices in specific populations, which may result in the under- or overtreatment of these patients. Even when guideline-based treatments are prescribed, socioeconomic, physical, or psychologic factors may affect non-Caucasian and older adult patient groups to a different extent and affect the application, effectiveness, and tolerability of these therapies. Individualized therapy based on tailored biology (genetics, proteomics, metabolomics), socioeconomic and cultural considerations, and individual goals and preferences may be the optimal approach for managing diverse patients. This comprehensive approach to personalized medicine is evolving, but in the interim, the scientific community should continue efforts focused on intensifying research in special populations, prescribing guideline-directed medical therapy unless contraindicated, and implementing evidence-based strategies including patient and family education and multidisciplinary team care in the management of patients.

    Severe acute respiratory failure requiring mechanical ventilation is one of the most frequent reasons for admission to the intensive care unit. Among the most frequent causes for admission are exacerbation of chronic obstructive pulmonary disease and acute respiratory failure with acute lung injury (ALI) or with criteria of acute respiratory distress syndrome (ARDS). These patients have a high risk of malnutrition due to the underlying disease, their altered catabolism and the use of mechanical ventilation. Consequently, nutritional evaluation and the use of specialized nutritional support are required. This support should alleviate the catabolic effects of the disease, avoid calorie overload and, in selected patients, to use omega-3 fatty acid- and antioxidant-enriched diets, which could improve outcome.

    This study examined the association of subjective nighttime sleep quality and daytime sleepiness with cognitive impairment in 105 adults (old) and 167 elders (≥ 60 years old) with heart failure. Nighttime sleep quality and daytime sleepiness were measured by the Pittsburgh Sleep Quality Index and the Epworth Sleepiness Scale. Cognitive impairment was assessed using a neuropsychological battery measuring attention, memory, and processing speed. Multivariate logistic regression was used. In adults, daytime sleepiness was associated with cognitive impairment, whereas poor nighttime sleep quality was associated with cognitive impairment in elders. Age may play an important role in how sleep impacts cognition in persons with heart failure. Improving nighttime sleep quality and daytime sleepiness in this population may improve cognition.

    The pathogenesis of ARDS is largely unknown, but many factors are known to predispose one to ARDS: sepsis, aspiration of gastric contents, pneumonia, fracture, multiple transfusions, cardiopulmonary bypass, burn, dissemination intravascular coagulation, pulmonary contusion, near drowning, and pancreatitis. ARDS is characterized by severe hypoxemia, diffuse pulmonary infiltrates, and decreased pulmonary compliance. Current treatment methods still result in 50% mortality. Studies are underway at the University of Cincinnati to determine if treatment with a synthetic pulmonary surfactant, Exosurf{sup {reg_sign}} (contains dipalmitoyl phosphatidyl choline, Burroughs-Wellcome), improves the prognosis of these patients. BALF from these patients, before and after treatment, was analyzed to determine if the treatment resulted in an increase in disaturated phospholipids (surfactant phospholipids) in the epithelial lining fluid and if the treatments reduced the concentration of markers of inflammation and toxicity in the BALF. This study indicates that the method of administering Exosurf{sup {reg_sign}} did not lead to an increase in surfactant lipid or protein in the bronchoalveolar region of the respiratory tract.

    Background: Chronic respiratory disease (CRD) causes substantial morbidity and mortality. Although the global CRD epidemic collides with the tuberculosis (TB) epidemic in many low- and middle-income country settings, the risk of TB-associated CRD is not well described in countries with a high burden of TB. Methods: We recruited 136 patients with a history of sputum smear-positive pulmonary TB (PTB) from the TB clinic at Omdurman Teaching Hospital in Khartoum, Sudan, and 136 age- and sex-matched community controls, between 28 July 2013 and 30 December 2013. Data were collected using standardised questionnaires and spirometry was performed before and after bronchodilator. Results: The mean age of the subjects with previous PTB and controls was respectively 44.0 years (SD 8.5) and 44.5 years (SD 8.6), with 27.2% females in both groups. Chronic respiratory symptoms such as chronic cough (OR 6.67, 95%CI 2.98-14.90, P morbilidad y mortalidad. Aunque la epidemia mundial de EPC rivaliza con la epidemia de tuberculosis (TB) en muchos entornos de países con bajos y medianos recursos, el riesgo de aparición de EPC asociado con la TB se ha descrito cabalmente en los países con una alta carga de morbilidad por TB. Métodos: Entre el 28 de julio y el 30 de diciembre del 2013, participaron en el estudio 136 pacientes con antecedente de tuberculosis pulmonar (TBP) y baciloscopia positiva del esputo que habían recibido tratamiento en el consultorio de neumología del Hospital Universitario Omdurman de Jartún, en Sudán, y 136 testigos sanos de la comunidad, emparejados en función de la edad y el sexo. Se recogieron datos mediante cuestionarios normalizados y se practicó una espirometría antes y despuès una prueba de broncodilatación. Resultados: El promedio de la edad en el grupo de los casos fue 44,0 (desviación estándar 8,5 años) y en el grupo de testigos fue 44,5 años (8,6 años); la proporción de mujeres en ambos grupos fue 27,2%.

    Full Text Available Abstract Background Since the first outbreak of a respiratory illness caused by H1N1 virus in Mexico, several reports have described the need of intensive care or extracorporeal membrane oxygenation (ECMO assistance in young and often healthy patients. Here we describe our experience in H1N1-induced ARDS using both ventilation strategy and ECMO assistance. Methods Following Italian Ministry of Health instructions, an Emergency Service was established at the Careggi Teaching Hospital (Florence, Italy for the novel pandemic influenza. From Sept 09 to Jan 10, all patients admitted to our Intensive Care Unit (ICU of the Emergency Department with ARDS due to H1N1 infection were studied. All ECMO treatments were veno-venous. H1N1 infection was confirmed by PCR assayed on pharyngeal swab, subglottic aspiration and bronchoalveolar lavage. Lung pathology was evaluated daily by lung ultrasound (LUS examination. Results A total of 12 patients were studied: 7 underwent ECMO treatment, and 5 responded to protective mechanical ventilation. Two patients had co-infection by Legionella Pneumophila. One woman was pregnant. In our series, PCR from bronchoalveolar lavage had a 100% sensitivity compared to 75% from pharyngeal swab samples. The routine use of LUS limited the number of chest X-ray examinations and decreased transportation to radiology for CT-scan, increasing patient safety and avoiding the transitory disconnection from ventilator. No major complications occurred during ECMO treatments. In three cases, bleeding from vascular access sites due to heparin infusion required blood transfusions. Overall mortality rate was 8.3%. Conclusions In our experience, early ECMO assistance resulted safe and feasible, considering the life threatening condition, in H1N1-induced ARDS. Lung ultrasound is an effective mean for daily assessment of ARDS patients.

    Full Text Available Background and Objective: Acute exacerbation of chronic obstructive pulmonary disease (COPD leads to increased morbidity, mortality and requirement of invasive mechanical ventilation (MV. The aim of this study was to identify predictors of need of MV in these patients. Materials and Methods: Clinical symptomatology, demographic profile, biochemical parameters including renal functions, liver functions and acid base parameters, and acute physiology and chronic health evaluation II (APACHE II score at the time of admission were recorded in 100 patients of COPD exacerbation. Various parameters were compared between patients in whom MV was required with those managed with medical therapy. Results: MV was required in 73% of the patients. Parameters found to be independent predictors of need of MV were: Admission APACHE-II score ≥ 11.5 {adjusted odds ratio (OR [95% confidence interval (CI]: 1.42 [1.08-1.86]; P = 0.012}, first day pH ≤ 7.28 (adjusted OR [95% CI]: 1.09 [1.02-1.15]; P = 0.008, first day PaCO 2 ≥ 68.6 mmHg (adjusted OR [95% CI]: 1.09 [1.02-1.15]; P = 0.004 and worse premorbid functional status (adjusted OR [95% CI]: 17.01 [1.95-148.68]; P = 0.01. Conclusions: Underlying disease severity as assessed by premorbid functional status and APACHE-II score, and the acuity of respiratory system decompensation as assessed by the admitting arterial pH and PaCO 2 , are independent predictors of need of MV in patients with exacerbation of COPD.

Methods The data of 78 cases of COPD patients from June 2007 to June 2010 were retrospectively analyzed. Results Out of 78 hospitalized COPD patients, 45 cases had respiratory failure. The morbidity of respiratory failure was associated with the annual times of episodes, systemic nutritional status, COPD classification, inhaled corticosteroids application, acid -base balance disorders, high blood sugar,fungal infections and other f~tors. Respiratory failure had no relationship with age and the course of the disease ( P > 0.05 ). In the group who died of respiratory failure, the rate of combined complications including heart failure, pulmonary encephalopathy and acid - base disturbance was as high as 100%. Conclusion The causes of respiratory failure in COPD were complicated and risk of death respiratory failure was significantly increased.

    To study monitoring hemodynamics and oxygen dynamics of adult respiratory distress syndrome (ARDS)secondary to high altitude pulmonary edema (HAPE),we performed clinic and laboratory studies in 8 patients who preliminarily developed high altitude cerebral edema (HACE) and then ARDS occurred at an altitude of 4500 m.After an initial emergency treatment on high mountains,all the patients were rapidly transported to a hospital at a lower altitude of 2808 m.The right cardiac catheterizations were carried out within 5 h after hospitalized.The monitoring hemodynamics and oxygen dynamics were studied via a thermodilution Swan-Gaze catheter.The results showed that before treatments at the beginning of monitoring,there presented a significant pulmonary artery hypertension with a decreased cardiac function,and a lower oxygen metabolism in all the 8 patients.However,after some effective treatments,including mechanical ventilation and using dexamethasone,furosemide,etc,four days later the result of a repeated monitoring showed that their pulmonary artery pressure had been decreased with an improved cardiac function with all the oxygen metabolic indexes increased significantly.Our studies suggested that performing monitoring hemodynamics in patients with ARDS secondary to HAPE will define the clinical therapeutic measures which will benefit the outcome.

    Full Text Available Objective: Noninvasive positive pressure ventilation (NIPPV has been shown to decrease the need for invasive mechanical ventilation (MV in patients presenting with acute respiratory failure (ARF. We conducted a prospective study to assess if NIPPV use, in a developing country, was associated with clinical and physiological improvements. Design: Prospective observational study. Materials and Methods: Forty patients admitted to a medical intensive care unit during a 2-year period who fulfilled criteria for inclusion formed the study cohort to receive NIPPV. Findings: Baseline (mean ± SD pH, PaCO 2 and PaO 2 were 7.25 ± 0.08, 76.6 ± 20.9 and 79.18 ± 40.56 mmHg respectively. The primary indication for NIPPV was hypercapnic respiratory failure (n = 36, 90%. The success rate with NIPPV was 85%, with 34 of 40 patients weaned successfully. Significant improvements were observed at 1 hour following institution of NIPPV in pH (7.31 ± 0.09, P < 0.001 and PaCO 2 (65 ± 17.9, P < 0.001. These improvements continued up to the time of weaning (pH 7.38 ± 0.08, PaCO 2 54.7 ± 20 and maintained (within 12 h postweaning from the ventilator (pH 7.39 ± 0.08, PaCO 2 51.9 ± 12.4. No significant change in the PaO 2 was observed during NIPPV; PaO 2 after 1 h, prior to weaning and after weaning was 90.53 ± 42.85, 84.80 ± 33.76, 78.71 ± 43.81 respectively. Conclusion: This study has demonstrated benefits of NIPPV in avoiding the need for invasive MV in patients presenting with ARF of diverse etiology, with results comparable to developed nations. Increased use of NIPPV in ARF is likely to impact favorably in nations with limited resources.

    Preserved ejection fraction heart failure (HFpEF) diagnosis remains controversial, and invasive left ventricular (LV) hemodynamic evaluation and/or exercise testing is advocated by many. The stiffer HFpEF myocardium may show impaired stroke volume (SV) variation induced by fluctuating LV filling pressure during ventilation. Our aim was to investigate spectral transfer function (STF) gain from end-diastolic pressure (EDP) to indexed SV (SVi) in experimental HFpEF. Eighteen-week-old Wistar-Kyoto (WKY) and ZSF1 lean (ZSF1 Ln) and obese rats (ZSF1 Ob) randomly underwent LV open-chest (OC, n = 8 each group) or closed-chest hemodynamic evaluation (CC, n = 6 each group) under halogenate anesthesia and positive-pressure ventilation at constant inspiratory pressure. Beat-to-beat fluctuations in hemodynamic parameters during ventilation were assessed by STF. End-diastolic stiffness (βi) and end-systolic elastance (Eesi) for indexed volumes were obtained by inferior vena cava occlusion in OC (multibeat) or single-beat method estimates in CC. ZSF1 Ob showed higher EDP spectrum (P heart catheterization-derived EDP surrogates to noninvasively determined SV as screening/diagnostic tool to assess myocardial stiffness in HFpEF.

    Full Text Available Pulmonary interstitial glycogenosis (PIG is a rare interstitial lung disease in the newborns. We report on the clinical presentation and pathological findings of a full-term male infant with pulmonary hypertension requiring extracorporeal membrane oxygenation (ECMO. An open lung biopsy demonstrated interstitial changes resembling pulmonary interstitial glycogenosis as well as bronchopulmonary dysplasia (BPD, without convincing evidence of maturational arrest, infection, alveolar proteinosis, or alveolar capillary dysplasia. The boy was treated with glucocorticoids and, after a few days, was weaned from ECMO. A few hours later, the patient died due to acute severe pulmonary hypertension with acute right ventricular failure. The etiology and underlying pathogenic mechanisms of PIG are unknown. The clinical outcomes are quite varied. Deaths have been reported when PIG exists with abnormal lung development and pulmonary vascular growth and congenital heart disease. No mortality has been reported in PIG together with BPD in full-term infants. In this article, we reported on a full-term infant with interstitial changes resembling PIG and BPD who expired despite no convincing evidence of an anatomical maturational arrest or congenital heart disease.

    Community-acquired pneumonia (CAP) is the third cause of death worldwide. Viruses are frequently detected in adult CAP. Highly sensitive diagnostic techniques should be used due to poor viral shedding. Different sampling methods can affect viral detection, being necessary to establish the optimal type of sample for identifying respiratory viruses in adults. The detection rates of respiratory viruses by Luminex xTAG® RVP fast assay, real time RT-PCR (rtRT-PCR) (Sacace®), and immunofluorescence assay (IFA) in adult CAP were performed in nasopharyngeal swabs (NPS) and aspirates (NPA) from 179 hospitalized adults. Positivity was 47.5% for Luminex®, 42.5% for rtRT-PCR (P = 0.3), and 2.7% for IFA (2.7%) (P viruses in 112 NPA and 35 (34.3%) and 31 (30.4%) in 102 NPS, respectively (P viruses in CAP adults. Both molecular techniques yielded better results with nasopharyngeal aspirate than swabs.

    2010-12-01

    Full Text Available Abstract Background Sox9 (Sry box containing gene 9 is a DNA-binding transcription factor involved in chondrocyte development and sex determination. The protein's absence in testicular Sertoli nurse cells has been shown to disrupt testicular function in adults but little is known at the genome-wide level about molecular events concomitant with testicular break-down. Methods To determine the genome-wide effect on mRNA concentrations triggered by the absence of Sox9 in Sertoli cells we analysed adult testicular tissue from wild-type versus mutant mice with high-density oligonucleotide microarrays and integrated the output of this experiment with regulatory motif predictions and protein-protein network data. Results We report the genome-wide mRNA signature of adult testes lacking Sox9 in Sertoli cells before and after the onset of late spermatogenic failure as compared to fertile controls. The GeneChip data integrated with evolutionarily conserved Sox9 DNA binding motifs and regulatory network data identified genes involved in feminization, stress response and inflammation. Conclusions Our results extend previous observations that genes required for female gonadogenesis are up-regulated in the absence of Sox9 in fetal Sertoli cells to the adult stage. Importantly, we identify gene networks involved in immunological processes and stress response which is reminiscent of a phenomenon occurring in a sub-group of infertile men. This suggests mice lacking Sox9 in their Sertoli cells to be a potentially useful model for adult human testicular failure.

    Full Text Available Abstract Background Patients with acute exacerbation of chronic obstructive pulmonary disease (COPD commonly require hospitalization and admission to intensive care unit (ICU. It is useful to identify patients at the time of admission who are likely to have poor outcome. This study was carried out to define the predictors of mortality in patients with acute exacerbation of COPD and to device a scoring system using the baseline physiological variables for prognosticating these patients. Methods Eighty-two patients with acute respiratory failure secondary to COPD admitted to medical ICU over a one-year period were included. Clinical and demographic profile at the time of admission to ICU including APACHE II score and Glasgow coma scale were recorded at the time of admission to ICU. In addition, acid base disorders, renal functions, liver functions and serum albumin, were recorded at the time of presentation. Primary outcome measure was hospital mortality. Results Invasive ventilation was required in 69 patients (84.1%. Fifty-two patients survived to hospital discharge (63.4%. APACHE II score at the time of admission to ICU {odds ratio (95 % CI: 1.32 (1.138–1.532; p Conclusion APACHE II score at admission and SA levels with in 24 hrs after admission are independent predictors of mortality for patients with COPD admitted to ICU. The equation derived from these two parameters is useful for predicting outcome of these patients.

    Full Text Available BACKGROUND: Measurements of Energy Expenditure (EE at rest (REE and during physical activities are increasing in interest in chronic patients. In this study we aimed at evaluating the validity/reliability of the SenseWear®Armband (SWA device in terms of REE and EE during assisted walking in Chronic Respiratory Failure (CRF patients receiving long-term oxygen therapy (LTOT. METHODOLOGY/PRINCIPAL FINDINGS: In a two-phase prospective protocol we studied 40 severe patients and 35 age-matched healthy controls. In phase-1 we determined the validity and repeatability of REE measured by SWA (REEa in comparison with standard calorimetry (REEc. In phase-2 we then assessed EE and Metabolic Equivalents-METs by SWA during the 6-minute walking test while breathing oxygen in both assisted (Aid or unassisted (No-Aid modalities. When compared with REEc, REEa was slightly lower in patients (1351±169 vs 1413±194 kcal/day respectively, p<0.05, and less repeatable than in healthy controls (0.14 and 0.43 coefficient respectively. COPD patients with CRF patients reported a significant gain with Aid as compared with No-Aid modality in terms of meters walked, perceived symptoms and EE. CONCLUSIONS/SIGNIFICANCE: SWA provides a feasible and valid method to assess the energy expenditure in CRF patients on LTOT, and it shows that aided walking results in a substantial energy saving in this population.

    Full Text Available Kaposi Sarcoma (KS is the most common malignancy associated with Acquired Immune Deficiency Syndrome (AIDS and is caused by Human Herpesvirus 8 (HHV 8 or Kaposi Sarcoma Herpesvirus (KSHV. In about 90% of cases Kaposi Sarcoma is associated with cutaneous lesions; however visceral disease can occur in the absence of cutaneous involvement. In the era of Highly Active Antiretroviral Therapy (HAART, the incidence of KS has declined. Clinical features of pulmonary KS might be difficult to distinguish from pneumonia in the immunocompromised patients and could lead to diagnostic challenges. First-line treatment of KS is with HAART and the incidence has declined with its use. Systemic chemotherapy may play a role depending on the extent of the disease. We report the case of a young man who presented with pulmonary symptoms and was later found to have pulmonary KS. Interestingly this diagnosis was made in the absence of the classic skin lesions. His disease was complicated by progressive respiratory failure and he eventually died.

    Methods: Total 33 subjects aged between 15-73 years, 21 male and 12 female patients were selected for study from ICU, Neurological trauma unit Pune. Inclusion criteria: All subjects with respiratory failure due to different pathologies like ARDS, Pulmonary edema, pneumonia, tuberculosis, collection of fluid in pleural cavity with underlying lung collapse. Exclusion criteria: Unstable cardiac conditions, unstable fractures, unstable hemodynamic, recently operated cardiac subjects. The patients were kept in supine position, lateral and prone and vitals like BP, HR, RR and oxygen saturation with help of pulse oximeter noted just before position. Thorough ET or tracheostomy suction was done. Before turning patient if any intercostal drain present was clamped. Results: Paired t-test was used. p values for prone and bilateral side lying positions was < 0.05 showing its significance for above mentioned 3-positions. p value for supine was not < 0.05 showing its non-significance. Conclusion: The study concluded that oxygen saturation improves in prone lying and side lying position as compared to supine lying. But this improvement is quiet significant in prone position as compared to side lying. [Int J Res Med Sci 2015; 3(7.000: 1627-1631

    2014-01-01

    Introduction Comprehensively evaluating the efficacy and safety of high-frequency oscillatory ventilation (HFOV) is important to allow clinicians who are using or considering this intervention to make appropriate decisions. Methods To find randomized controlled trials (RCTs) comparing HFOV with conventional mechanical ventilation (CMV) as an initial treatment for adult ARDS patients, we searched electronic databases (including PubMed, MedLine, Springer Link, Elsevier Science Direct, ISI web of knowledge, and EMBASE) with the following terms: “acute respiratory distress syndrome”, “acute lung injury”, and “high frequency oscillation ventilation”. Additional sources included reference lists from the identified primary studies and relevant meta-analyses. Two investigators independently screened articles and extracted data. Meta-analysis was conducted using random-effects models. Results We included 6 RCTs with a total of 1,608 patients in this meta-analysis. Compared with CMV, HFOV did not significantly reduce the mortality at 30 or 28 days. The pooled relative risk (RR) was 1.051 (95% confidence interval (CI) 0.813 to 1.358). ICU mortality was also not significantly reduced in HFOV group, with a pooled RR of 1.218 (95% CI 0.925 to 1.604). The pooled effect sizes of HFOV for oxygenation failure, ventilation failure and duration of mechanical ventilation were 0.557 (95% CI 0.351 to 0.884), 0.892 (95% CI 0.435 to 1.829) and 0.079 (95% CI −0.045 to 0.203), respectively. The risk of barotrauma and hypotension were similar between the CMV group and HFOV group, with a RR of 1.205 (95% CI 0.834 to 1.742) and a RR of 1.326 (95% CI 0.271 to 6.476), respectively. Conclusions Although HFOV seems not to increase the risk of barotrauma or hypotension, and reduces the risk of oxygenation failure, it does not improve survival in adult acute respiratory distress syndrome patients.

    The impact of lifelong exposure to myocardial dysfunction in populations with congenital heart disease (CHD) is becoming increasingly recognized. Most children born with CHD now reach adulthood and the long-term sequelae of treatment are contributing to substantial comorbidity. The combination of structural changes present at birth with changes resulting from cardiac surgery can result in heart failure. This article reports on the current state of knowledge on the epidemiology of heart failure in this patient population.

    The National Free Antiretroviral Treatment Program was implemented in Jiangsu Province, China in 2005. We conducted a retrospective, open cohort study to determine treatment failure rates and associated risk factors. Data were obtained from the national web-based antiretroviral treatment database. WHO criteria were used to define immunologic treatment failure. Kaplan-Meier methods were used to determine treatment failure rates and Cox proportional hazards modeling was used to identify risk factors. A total of 5,083 (87.8%) having at least one CD4 cell count measure were included from 2005 to 2013. Overall, 30.4% had immunologic treatment failure with cumulative treatment failure rates increasing to 50.5% at month 60 and 64.1% at month 90. Factors predicting treatment failure included being treated in the Centers for Disease Control and Prevention system (HR 1.69, 95% CI 1.14–2.50, p = 0.009) or jail hospital (HR 1.20, 95% CI 1.08–1.34, p = 0.001), and having a baseline CD4 count >350 cells/uL (HR 2.37, 95% CI 1.94–2.89. p HIV patients. Providing second-line regimens and shifting treatment providers to professional hospitals should be considered to consolidate gains in averting morbidity and mortality. PMID:28220792

    Full Text Available INTRODUCTION: Influenza infections present with wide-ranging clinical features. We aim to compare the differences in presentation between influenza and non-influenza cases among those with febrile respiratory illness (FRI to determine predictors of influenza infection. METHODS: Personnel with FRI (defined as fever ≥ 37.5 °C, with cough or sore throat were recruited from the sentinel surveillance system in the Singapore military. Nasal washes were collected, and tested using the Resplex II and additional PCR assays for etiological determination. Interviewer-administered questionnaires collected information on patient demographics and clinical features. Univariate comparison of the various parameters was conducted, with statistically significant parameters entered into a multivariate logistic regression model. The final multivariate model for influenza versus non-influenza cases was used to build a predictive probability clinical diagnostic model. RESULTS: 821 out of 2858 subjects recruited from 11 May 2009 to 25 Jun 2010 had influenza, of which 434 (52.9% had 2009 influenza A (H1N1, 58 (7.1% seasonal influenza A (H3N2 and 269 (32.8% influenza B. Influenza-positive cases were significantly more likely to present with running nose, chills and rigors, ocular symptoms and higher temperature, and less likely with sore throat, photophobia, injected pharynx, and nausea/vomiting. Our clinical diagnostic model had a sensitivity of 65% (95% CI: 58%, 72%, specificity of 69% (95% CI: 62%, 75%, and overall accuracy of 68% (95% CI: 64%, 71%, performing significantly better than conventional influenza-like illness (ILI criteria. CONCLUSIONS: Use of a clinical diagnostic model may help predict influenza better than the conventional ILI definition among young adults with FRI.

    Full Text Available Type 2C and 2D limb girdle muscular dystrophies (LGMD are a group of autosomal recessive limb girdle muscular dystrophies manifested by proximal myopathy, impaired respiratory muscle function and cardiomyopathy. The correlation and the prognostic impact of respiratory and heart impairment are poorly described. We aimed to describe the long-term cardiac and respiratory follow-up of these patients and to determine predictive factors of cardio-respiratory events and mortality in LGMD 2C and 2D.We reviewed the charts of 34 LGMD patients, followed from 2005 to 2015, to obtain echocardiographic, respiratory function and sleep recording data. We considered respiratory events (acute respiratory failure, pulmonary sepsis, atelectasis or pneumothorax, cardiac events (acute heart failure, significant cardiac arrhythmia or conduction block, ischemic stroke and mortality as outcomes of interest for the present analysis.A total of 21 patients had type 2C LGMD and 13 patients had type 2D. Median age was 30 years [IQR 24-38]. At baseline, median pulmonary vital capacity (VC was 31% of predicted value [20-40]. Median maximal inspiratory pressure (MIP was 31 cmH2O [IQR 20.25-39.75]. Median maximal expiratory pressure (MEP was 30 cm H2O [20-36]. Median left ventricular ejection fraction (LVEF was 55% [45-64] with 38% of patients with LVEF <50%. Over a median follow-up of 6 years, we observed 38% respiratory events, 14% cardiac events and 20% mortality. Among baseline characteristics, LVEF and left ventricular end diastolic diameter (LVEDD were associated with mortality, whilst respiratory parameters (VC, MIP, MEP and the need for home mechanical ventilation (HMV were associated with respiratory events.In our cohort of severely respiratory impaired type 2C and 2D LGMD, respiratory morbidity was high. Cardiac dysfunction was frequent in particular in LGMD 2C and had an impact on long-term mortality.ClinicalTrials.gov NCT02501083.

    On May 15, 2014, CDC was notified of two laboratory-confirmed measles cases in the Federated States of Micronesia (FSM), after 20 years with no reported measles. FSM was assisted by the World Health Organization (WHO), the United Nations Children’s Fund (UNICEF), and CDC in investigating suspected cases, identify contacts, conduct analyses to guide outbreak vaccination response, and review vaccine cold chain practices. During February–August, three of FSM’s four states reported measles cases: Kosrae (139 cases), Pohnpei (251), and Chuuk (3). Two thirds of cases occurred among adults aged ≥20 years; of these, 49% had received ≥2 doses of measles-containing vaccine (MCV). Apart from infants aged vaccination, measles incidence was lower among children than adults. A review of current cold chain practices in Kosrae revealed minor weaknesses; however, an absence of historical cold chain maintenance records precluded an evaluation of earlier problems. Each state implemented vaccination campaigns targeting children as young as age 6 months through adults up to age 57 years. The preponderance of cases in this outbreak associated with vaccine failure in adults highlights the need for both thorough case investigation and epidemiologic analysis to guide outbreak response vaccination. Routine childhood vaccination coverage achieved in recent years limited the transmission of measles among children. Even in areas where transmission has not occurred for years, maintaining high 2-dose MCV coverage through routine and supplemental immunization is needed to prevent outbreaks resulting from increased measles susceptibility in the population.

    We tested the hypothesis that high frequency ventilation affects respiratory system mechanical functions in C57BL/6J and BALB/c mice. We measured respiratory mechanics by the forced oscillation technique over 1h in anesthetized, intubated, ventilated BALB/c and C57BL/6J male mice. We did not detect any change in airway resistance, Rn, tissue damping, G, tissue elastance, H and hysteresivity, eta in BALB/c mice during 1h of ventilation at 150 or at 450 breaths/min; nor did we find a difference between BALB/c mice ventilated at 150 breaths/min compared with 450 breaths/min. Among C57BL/6J mice, except for H, all parameters remained unchanged over 1h of ventilation in mice ventilated at 150 breaths/min. However, after 10 and 30 min of ventilation at 450 breaths/min, Rn, and respiratory system compliance were lower, and eta was higher, than their starting value. We conclude that high frequency mechanical ventilation affects respiratory system mechanics differently in C57BL/6J and BALB/c adult mice.

    Light detection and ranging (LIDAR) can estimate daily volumes of sand dust particles from the East Asian desert to Japan. The objective of this study was to investigate the relationship between sand dust particles and pulmonary function, and respiratory symptoms in adult patients with asthma. One hundred thirty-seven patients were included in the study. From March 2013 to May 2013, the patients measured their morning peak expiratory flow (PEF) and kept daily lower respiratory symptom diaries. A linear mixed model was used to estimate the correlation of the median daily levels of sand dust particles, symptoms scores, and PEF. A heavy sand dust day was defined as an hourly concentration of sand dust particles of >0.1 km(-1). By this criterion, there were 8 heavy sand dust days during the study period. Elevated sand dust particles levels were significantly associated with the symptom score (0.04; 95% confidence interval (CI); 0.03, 0.05), and this increase persisted for 5 days. There was no significant association between PEF and heavy dust exposure (0.01 L/min; 95% CI, -0.62, 0.11). The present study found that sand dust particles were significantly associated with worsened lower respiratory tract symptoms in adult patients with asthma, but not with pulmonary function.

    Chronic respiratory failure is a complex entity of varied etiology and physio-pathological mechanisms. It is mainly characterised by the respiratory system's difficulty in ensuring correct aeration at rest, resulting initially in insufficient oxygenation of arterial blood. Treatment is adapted to each etiology and aims to compensate for respiratory failure and to ensure the oxygenation of the organism.

    Problematic Internet use has been associated with the neglect of valued activities such as work, exercise, social activities, and relationships. In the present study, we expanded the understanding of problematic Internet use by identifying an important predictor of the inability to curb Internet use despite the desire to do so. Specifically, in a college student sample reporting a mean of 27.8 h of recreational Internet use in the past week, we investigated the role of distress intolerance (DI)-an individual difference variable that refers to the inability of an individual to tolerate emotional discomfort and to engage in goal-directed behavior when distressed-to predict the failure to meet personal restrictions on Internet use. Consistent with hypotheses, DI emerged as a significant predictor of the failure to meet self-control goals in both bivariate and multivariate models, indicating that DI offers unique prediction of self-control failure with problematic Internet use. Given that DI is a modifiable trait, these results encourage consideration of DI-focused early intervention strategies.

    Full Text Available BACKGROUND: In addition to SARS associated coronaviruses, 4 non-SARS related human coronaviruses (HCoVs are recognized as common respiratory pathogens. The etiology and clinical impact of HCoVs in Chinese adults with acute upper respiratory tract infection (URTI needs to be characterized systematically by molecular detection with excellent sensitivity. METHODOLOGY/PRINCIPAL FINDINGS: In this study, we detected 4 non-SARS related HCoV species by real-time RT-PCR in 981 nasopharyngeal swabs collected from March 2009 to February 2011. All specimens were also tested for the presence of other common respiratory viruses and newly identified viruses, human metapneumovirus (hMPV and human bocavirus (HBoV. 157 of the 981 (16.0% nasopharyngeal swabs were positive for HCoVs. The species detected were 229E (96 cases, 9.8%, OC43 (42 cases, 4.3%, HKU1 (16 cases, 1.6% and NL63 (11 cases, 1.1%. HCoV-229E was circulated in 21 of the 24 months of surveillance. The detection rates for both OC43 and NL63 were showed significantly year-to-year variation between 2009/10 and 2010/11, respectively (P<0.001 and P = 0.003, and there was a higher detection frequency of HKU1 in patients aged over 60 years (P = 0.03. 48 of 157(30.57% HCoV positive patients were co-infected. Undifferentiated human rhinoviruses and influenza (Flu A were the most common viruses detected (more than 35% in HCoV co-infections. Respiratory syncytial virus (RSV, human parainfluenza virus (PIV and HBoV were detected in very low rate (less than 1% among adult patients with URTI. CONCLUSIONS/SIGNIFICANCE: All 4 non-SARS-associated HCoVs were more frequently detected by real-time RT-PCR assay in adults with URTI in Beijing and HCoV-229E led to the most prevalent infection. Our study also suggested that all non-SARS-associated HCoVs contribute significantly to URTI in adult patients in China.

    2016-04-01

    Assistance from informal caregivers such as family members, friends, or neighbors is crucial to adequately managing the complex care of heart failure (HF) patients. This study examined the lived experience of African American caregivers caring for African American patients with HF. Purposive sampling was used to recruit 10 participants who were formally interviewed. The interviews, analyzed using Colaizzi's steps, revealed six themes: layers of support, realization of self-neglect, experiencing the "blues," connecting with healthcare providers, unmet financial needs, and perception of nonadherence. The information regarding the experience of African American caregivers of HF patients obtained through this research will inform the delivery of culturally competent support to caregivers, thereby improving quality of life for both the HF patients and their caregivers.

  4. Depression Is Associated with Cognitive Dysfunction in Older Adults with Heart Failure

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Persons with heart failure (HF frequently exhibit cognitive impairment with deficits in attention and memory. Depression is common in HF though its possible contribution to cognitive impairment is unknown. Cognitive dysfunction and depression may share common mechanisms in HF, as both are associated with similar abnormalities on neuroimaging. A total of 116 participants with HF (68.53±9.30 years completed a neuropsychological battery and self-report measures of depression. Regression models showed depression incrementally and independently predicted test performance in all cognitive domains. Follow-up partial correlations revealed that greater depressive symptoms were associated with poorer performance on tests of attention, executive function, psychomotor speed, and language. These results indicate that depressive symptoms are associated with poorer cognitive performance in HF though further work is needed to clarify mechanisms for this association and possible cognitive benefits of treating depression in persons with HF.

    2016-12-22

    In the Swedish Building Energy, Technical Status and Indoor environment study, a total of 1160 adults from 605 single-family houses answered a questionnaire on respiratory health. Building inspectors investigated the homes and measured temperature, air humidity, air exchange rate, and wood moisture content (in attic and crawl space). Moisture load was calculated as the difference between indoor and outdoor absolute humidity. Totally, 7.3% were smokers, 8.7% had doctor' diagnosed asthma, 11.2% current wheeze, and 9.5% current asthma symptoms. Totally, 50.3% had respiratory infections and 26.0% rhinitis. The mean air exchange rate was 0.36/h, and the mean moisture load 1.70 g/m(3) . Damp foundation (OR=1.79, 95% CI 1.16-2.78) was positively associated while floor constructions with crawl space (OR=0.49, 95% CI 0.29-0.84) was negatively associated with wheeze. Concrete slabs with overlying insulation (OR=2.21, 95% CI 1.24-3.92) and brick façade (OR=1.71, 95% CI 1.07-2.73) were associated with rhinitis. Moisture load was associated with respiratory infections (OR=1.21 per 1 g/m(3) , 95% CI 1.04-1.40) and rhinitis (OR=1.36 per 1 g/m(3) , 95% CI 1.02-1.83). Air exchange rate was associated with current asthma symptoms (OR=0.85 per 0.1/h, 95% CI 0.73-0.99). Living in homes with damp foundation, concrete slabs with overlying insulation, brick façade, low ventilation flow, and high moisture load are risk factors for asthma, rhinitis, and respiratory infections.

  6. Loss of extracellular superoxide dismutase leads to acute lung damage in the presence of ambient air: a potential mechanism underlying adult respiratory distress syndrome.

    The extracellular superoxide dismutase 3 (SOD3) is highly expressed in both blood vessels and lungs. In different models of pulmonary injury, SOD3 is reduced; however, it is unclear whether this contributes to lung injury. To study the role of acute SOD3 reduction in lung injury, the SOD3 gene was deleted in adult mice by using the Cre-Lox technology. Acute reduction of SOD3 led to a fivefold increase in lung superoxide, marked inflammatory cell infiltration, a threefold increase in the arterial-alveolar gradient, respiratory acidosis, histological changes similar to those observed in adult respiratory distress syndrome, and 85% mortality. Treatment with the SOD mimetic MnTBAP and intranasal administration of SOD-containing polyketal microparticles reduced mortality, prevented the histological alterations, and reduced lung superoxide levels. To understand how mice with the SOD3 embryonic deletion survived without lung injury, gene array analysis was performed. These data demonstrated the up-regulation of 37 genes and down-regulation of nine genes, including those involved in cell signaling, inflammation, and gene transcription in SOD3-/- mice compared with either mice with acute SOD3 reduction or wild-type controls. These studies show that SOD3 is essential for survival in the presence of ambient oxygen and that acute loss of this enzyme can lead to severe lung damage. Strategies either to prevent SOD3 inactivation or to augment its levels might prove useful in the treatment of acute lung injury.

    Full Text Available Background. Medical comorbidity has been theorized to contribute to cognitive impairment in heart failure (HF patients. Specifically, type-2 diabetes mellitus (T2DM, a common coexisting condition among HF patients, may be an independent predictor of cognitive impairment. Nonetheless, the relationships between T2DM and other risk factors for cognitive impairment among persons with HF are unclear. Methods. Persons with HF (N=169, 34.3% women, age 68.57±10.28 years completed neuropsychological testing within a framework of an ongoing study. History of T2DM, along with other medical characteristics, was ascertained through a review of participants’ medical charts and self-report. Results. Many participants (34.9% had a comorbid T2DM diagnosis. After adjustment for demographic and medical characteristics, HF patients with T2DM evidenced significantly greater impairments across multiple cognitive domains than HF patients without T2DM: λ=.92, F(5,156=2.82, P=.018. Post hoc tests revealed significant associations between T2DM and attention (P=.003, executive function (P=.032, and motor functioning (P=.008. Conclusion. The findings suggest additive contributions of T2DM and HF to impairments in attention, executive function, and motor function. Future work is needed to elucidate the mechanisms by which T2DM exacerbates cognitive impairment in HF.

    Extra corporeal membrane oxygenation (ECMO) is a form of life support, which facilitates gas exchange outside the body via an oxygenator and a centrifugal pumping system. A paediatric cardiac ECMO programme was established in 2005 at Our Lady's Children's Hospital, Crumlin (OLCHC) and to date 75 patients have received ECMO, the majority being post operative cardiac patients. The outcome data compares favourably with international figures. ECMO has been most successful in the treatment of newborn infants with life threatening respiratory failure from conditions such as meconium aspiration, respiratory distress syndrome and respiratory infections. There is no formal paediatric respiratory ECMO programme at OLCHC, or anywhere else in Ireland. Currently, neonates requiring respiratory ECMO are transferred to centres in Sweden or the UK at an average cost of 133,000 Euros/infant, funded by the Health Service Executive E112 treatment abroad scheme. There is considerable morbidity associated with the transfer of critically ill infants, as well as significant psycho-social impact on families. OLCHC is not funded to provide respiratory ECMO, although the equipment and expertise required are similar to cardiac ECMO and are currently in place. The average cost of an ECMO run at OLCHC is 65,000 Euros. There is now a strong argument for a fully funded single national cardiac and respiratory paediatric ECMO centre, similar to that for adult patients.

    Full Text Available BACKGROUND: Few comprehensive data exist on disease incidence for specific etiologies of acute respiratory illness (ARI in older children and adults in Africa. METHODOLOGY/PRINCIPAL FINDINGS: From March 1, 2007, to February 28, 2010, among a surveillance population of 21,420 persons >5 years old in rural western Kenya, we collected blood for culture and malaria smears, nasopharyngeal and oropharyngeal swabs for quantitative real-time PCR for ten viruses and three atypical bacteria, and urine for pneumococcal antigen testing on outpatients and inpatients meeting a ARI case definition (cough or difficulty breathing or chest pain and temperature >38.0 °C or oxygen saturation 5 years old (adjusted annual incidence 12.0 per 100 person-years, influenza A virus was the most common virus (22% overall; 11% inpatients, 27% outpatients and Streptococcus pneumoniae was the most common bacteria (16% overall; 23% inpatients, 14% outpatients, yielding annual incidences of 2.6 and 1.7 episodes per 100 person-years, respectively. Influenza A virus, influenza B virus, respiratory syncytial virus (RSV and human metapneumovirus were more prevalent in swabs among cases (22%, 6%, 8% and 5%, respectively than controls. Adenovirus, parainfluenza viruses, rhinovirus/enterovirus, parechovirus, and Mycoplasma pneumoniae were not more prevalent among cases than controls. Pneumococcus and non-typhi Salmonella were more prevalent among HIV-infected adults, but prevalence of viruses was similar among HIV-infected and HIV-negative individuals. ARI incidence was highest during peak malaria season. CONCLUSIONS/SIGNIFICANCE: Vaccination against influenza and pneumococcus (by potential herd immunity from childhood vaccination or of HIV-infected adults might prevent much of the substantial ARI incidence among persons >5 years old in similar rural African settings.

    Full Text Available Fulminant hepatic failure (FHF is characterized by massive hepatocellular injury, whose physiopathology is still unclear. Hepatitis B (HBV is probably the most common viral cause of FHF, while hepatitis A (HAV virus seem occurs less frequently. However, the host and viral factors that determine the outcome of these infections are poorly understood. In the present study, viral load and genotyping determining regions of HAV and HBV genomes were sequenced. Eight FHF patients and one patient with severe acute hepatitis (SAH were included. Liver and blood samples were collected during liver transplantation or necropsy procedures. HAV-RNA and HBV-DNA were extracted from serum, biopsy and paraffin liver. Nucleotide sequencing of HAV-RNA was performed from VP1/2A and HBV-DNA from PreS/S region. The amplified samples were quantified by Real-Time PCR. The cases of HAV infection were due to subgenotype IA. The cases of HBV infection were due to genotype A2 and D4. The case of HAV/HBV coinfection was infected by genotype IA and D3. Hepatitis A and B infection were associated with genotypes most prevalent in Brazil. In hepatitis A infection the mean of period evolution was 13 days. In hepatitis B, FHF patients infected by genotype D have a shorter period of evolution than FHF patients infected by genotype A (mean 15 v. 53 days. There was no association with genotype-determining region with the severity of hepatitis, however nucleotide differences and high viral load could be observed among FHF.

    Full Text Available Objectives: Studies have correlated second hand smoke (SHS with many diseases, especially respiratory effects. The goal of this study was to measure the impact of SHS on the respiratory symptoms and exhaled carbon monoxide. Material and Methods: The study population consisted of 50 young workers in restaurants serving waterpipes, 48 university students who sit frequently in the university cafeteria where cigarette smoking is allowed and 49 university students spending time in places where smoking is not allowed. Subjects completed questionnaires on socio-demographic characteristics, respiratory symptoms and exposure to SHS. Exhaled carbon monoxide levels were measured. ANOVA and Chi-square tests were used when applicable as well as linear and logistic regression analysis. Results: Exposure to cigarette smoke in university (adjusted odds ratio (ORa = 6.06 and occupational exposure to waterpipe smoke (ORa = 7.08 were predictors of chronic cough. Being married (ORa = 6.40, living near a heavy traffic road (ORa = 9.49 or near a local power generator (ORa = 7.54 appeared responsible for chronic sputum production. Moreover, predictors of chronic allergies were: being male (ORa = 7.81, living near a local power generator (ORa = 5.52 and having a family history of chronic respiratory diseases (ORa = 17.01. Carbon monoxide levels were augmented by the number of weekly hours of occupational exposure to waterpipe smoke (β = 1.46 and the number of daily hours of exposure to cigarette smoke (β = 1.14. Conclusions: In summary, young non-smoker subjects demonstrated more chronic cough and elevated carbon monoxide levels when exposed to SHS while the effect of waterpipe was even more evident.

WANG Xiaozhi(王晓芝),et al. Dept Respir & Intensive Care Unit, Binzhou Med Coll, Binzhou 256603. Chin J Tuberc Respir Dis 2007;30(1):44-47. Objective To compare the effects of BiPAP ventilation combined with lung recruitment maneuvers(LRM) with low tidal volume A/C ventilation in patients with acute respiratory distress syndrome (ARDS). Methods A prospective, randomized comparison of BiPAP mechanical ventilation combined with lung recruitment maneuvers(test group) with low tidal volume A/C ventilation (control group) was conducted in 28 patients with ARDS. FiO2/PaO2 ratio, respiratory system compliance(Cs), central venous pressure (CVP), duration of ventilation support were recorded at 0 h, 48 h and 72 h separately. The ventilation associated lung injury and mortality at 28 d were also recorded. Results The FiO2/PaO2 ratio were (298±16) and (309±16) cm H2O, Cs were (38.4±2.2) and (42.0±1.3) ml/cm H2O, CVP were (13.8±0.8) and (11.6±0.7) cm H2O in the test group at 48 h and 72 h separately. In the control group, FiO2/PaO2 ratio were (212±12) and (246±17) cm H2O, Cs were (29.5±1.3) and (29.0±1.0) ml/cm H2O, CVP were 18.6±1.1 and (16.8±1.0) cm H2O. The results were better in the test group as compared with the control group (t=10.03-29. 68, all P<0.01). The duration of ventilation support in the test group was shorter than the control group [(14±3) d vs (19±3)d, t=4.80, P<0.01]. The mortality in 28 d and ventilation associated lung injury were similar in the two groups. Conclusion The results show that combination of LRM with BiPAP mode ventilation, as compared with the control group, contributes to the improved FiO2/PaO2 ratio, pulmonary compliance, stable homodynamic and shorter duration of ventilation support in patients with ARDs.

  6. FSH-FSHR3-stem cells in ovary surface epithelium: basis for adult ovarian biology, failure, aging, and cancer.

    Despite extensive research, genetic basis of premature ovarian failure (POF) and ovarian cancer still remains elusive. It is indeed paradoxical that scientists searched for mutations in FSH receptor (FSHR) expressed on granulosa cells, whereas more than 90% of cancers arise in ovary surface epithelium (OSE). Two distinct populations of stem cells including very small embryonic-like stem cells (VSELs) and ovarian stem cells (OSCs) exist in OSE, are responsible for neo-oogenesis and primordial follicle assembly in adult life, and are modulated by FSH via its alternatively spliced receptor variant FSHR3 (growth factor type 1 receptor acting via calcium signaling and the ERK/MAPK pathway). Any defect in FSH-FSHR3-stem cell interaction in OSE may affect folliculogenesis and thus result in POF. Ovarian aging is associated with a compromised microenvironment that does not support stem cell differentiation into oocytes and further folliculogenesis. FSH exerts a mitogenic effect on OSE and elevated FSH levels associated with advanced age may provide a continuous trigger for stem cells to proliferate resulting in cancer, thus supporting gonadotropin theory for ovarian cancer. Present review is an attempt to put adult ovarian biology, POF, aging, and cancer in the perspective of FSH-FSHR3-stem cell network that functions in OSE. This hypothesis is further supported by the recent understanding that: i) cancer is a stem cell disease and OSE is the niche for ovarian cancer stem cells; ii) ovarian OCT4-positive stem cells are regulated by FSH; and iii) OCT4 along with LIN28 and BMP4 are highly expressed in ovarian cancers.

    Air pollution in the valley of Mexico is a risk to human health due to the high levels of ozone, acidic sulfates, nitrogen oxides, heavy metals and polycyclic aromatic hydrocarbons present. Epidemiologic studies have found an increase incidence of adverse respiratory symptoms among the residents of Mexico City. Histopathologic changes and DNA strand breaks have been observed in the nasal cells of residents of an area with high ozone levels. Since the nasal respiratory epithelium is directly exposed to air pollution we decided to investigate the frequency of MN in this tissue, in a group of 60 young adults (20-25 years old) that live in Mexico City and to compare it with the frequency of MN observed in a similar group of 60 individuals living in Merida, an urban area of the Yucatan peninsula, with lower air pollution. Volunteers completed questionnaires to give information about their health status, smoking habits and previous exposure to confounding factors such as radiation. Nasal cells were obtained by gently scraping the inner turbinate. The cells were smeared on previously coded glass slides, fixed and then stained with Feulgen`s method. 6000 cells were scored for each individual. Results from the analysis of twenty nasal cell samples from Mexico City residents and thirteen samples from Merida residents do not show significant differences in MN prevalence, although Mexico City showed in average a 50% increase in the frequency of MN. The presence of MN was not associated to smoking in either group. Condensed, karyorrhetic and karyolitic nuclei predominated (p<0.05) among the cell samples from Mexico City residents. These changes occur as an response to cellular injury in normal nonkeratinizing epithelium or can be observed in cell undergoing necrosis following injury by agents that cause perturbation of the cellular environment. These preliminary results showed clear cytotoxic effects in the nasal respiratory epithelium of Mexico City residents.

    2003-07-01

    Our lab has previously shown that when administered acutely, the methylxanthine theophylline can activate a latent respiratory motor pathway to restore function to the hemidiaphragm paralyzed by an ipsilateral C2 spinal cord hemisection. The recovery is mediated by the antagonism of CNS adenosine A1 receptors. The objective of the present study was to assess quantitatively recovery after chronic theophylline administration, the effects of weaning from the drug, and the effects of the drug on adenosine A1 receptor mRNA expression in adult rats subjected to a C2 hemisection. Rats subjected to a left C2 hemisection received theophylline orally for 3, 7, 12, or 30 days and were classified as 3D, 7D, 12D, or 30D respectively. Separate groups of 3D animals were weaned from drug administration for 7, 12, and 30 days before assessment of respiratory recovery. Additional groups of 7D and 12D animals were also weaned from drug administration for 7 and 12 days prior to assessment. Sham-operated controls received theophylline vehicle for similar periods. Quantitative assessment of recovered respiratory activity was conducted under standardized electrophysiologic recording conditions approximately 18 h after each drug application period. Serum theophylline analysis was conducted at the end of electrophysiologic recordings. Adenosine A1 receptor mRNA expression in the phrenic nucleus was assessed with in situ hybridization and immunohistochemistry. Chronic theophylline induced a dose-dependent effect on respiratory recovery over a serum theophylline range of 1.2-1.9 microg/ml. Recovery was characterized as respiratory-related activity in the left phrenic nerve and expressed as a percentage of activity in the homolateral nerve in noninjured animals under similar recording conditions. Recovered activity was 34.13 +/- 2.07, 55.89 +/- 2.96, 74.78 +/- 1.93, and 79.12 +/- 1.75% respectively in the 3D, 7D, 12D, and 30D groups. Theophylline-induced recovered activity persisted for as

    Full Text Available Question: After stroke, does respiratory muscle training increase respiratory muscle strength and/or endurance? Are any benefits carried over to activity and/or participation? Does it reduce respiratory complications? Design: Systematic review of randomised or quasi-randomised trials. Participants: Adults with respiratory muscle weakness following stroke. Intervention: Respiratory muscle training aimed at increasing inspiratory and/or expiratory muscle strength. Outcome measures: Five outcomes were of interest: respiratory muscle strength, respiratory muscle endurance, activity, participation and respiratory complications. Results: Five trials involving 263 participants were included. The mean PEDro score was 6.4 (range 3 to 8, showing moderate methodological quality. Random-effects meta-analyses showed that respiratory muscle training increased maximal inspiratory pressure by 7 cmH2O (95% CI 1 to 14 and maximal expiratory pressure by 13 cmH2O (95% CI 1 to 25; it also decreased the risk of respiratory complications (RR 0.38, 95% CI 0.15 to 0.96 compared with no/sham respiratory intervention. Whether these effects carry over to activity and participation remains uncertain. Conclusion: This systematic review provided evidence that respiratory muscle training is effective after stroke. Meta-analyses based on five trials indicated that 30 minutes of respiratory muscle training, five times per week, for 5 weeks can be expected to increase respiratory muscle strength in very weak individuals after stroke. In addition, respiratory muscle training is expected to reduce the risk of respiratory complications after stroke. Further studies are warranted to investigate whether the benefits are carried over to activity and participation. Registration: PROSPERO (CRD42015020683.

    Recently, several prognostic scoring systems for patients with severe acute respiratory distress syndrome (ARDS) requiring extracorporeal membrane oxygenation (ECMO) have been published. The aim of this study was to validate the established scoring systems for outcome prediction in Korean patients. We retrospectively reviewed the data of 50 patients on ECMO therapy in our center from 2012 to 2014. A calculation of outcome prediction scoring tools was performed and the comparison across various models was conducted. In our study, the overall hospital survival was 46% and successful weaning rate was 58%. The Predicting Death for Severe ARDS on V-V ECMO (PRESERVE) score showed good discrimination of mortality prediction for patients on ECMO with AUC of 0.80 (95% CI 0.66-0.90). The respiratory extracorporeal membrane oxygenation survival prediction (RESP) score and simplified acute physiology score (SAPS) II score also showed fair prediction ability with AUC of 0.79 (95% CI 0.65-0.89) and AUC of 0.78 (95% CI 0.64-0.88), respectively. However, the ECMOnet score failed to predict mortality with AUC of 0.51 (95% CI 0.37-0.66). When evaluating the predictive accuracy according to optimal cut-off point of each scoring system, RESP score had a best specificity of 91.3% and 66.7% of sensitivity, respectively. This study supports the clinical usefulness of the prognostic scoring tools for severe ARDS with ECMO therapy when applying to the Korean patients receiving ECMO.

    Full Text Available Routine HIV viral load (VL monitoring is the standard of care for persons receiving antiretroviral therapy (ART in developed countries. Although the World Health Organization recommends annual VL monitoring of patients on ART, recognizing difficulties in conducting routine VL testing, the WHO continues to recommend targeted VL testing to confirm treatment failure for persons who meet selected immunologic and clinical criteria. Studies have measured positive predictive value (PPV, negative predictive value, sensitivity and specificity of these criteria among patients receiving first-line ART but not specifically among those on second-line or subsequent regimens. Between 2008 and 2011, adult ART patients in Nyanza, Kenya who met national clinical or immunologic criteria for treatment failure received targeted VL testing.

Of 12,134 patient specimens tested, 2,874 (23.7% were virologically confirmed as treatment failures. The PPV for 2,834 first-line ART patients who met either the clinical or immunologic criteria for treatment failure was 34.4% (95% CI 33.2-35.7, 33.1% (95% CI 24.7-42.3 for the 40 patients on second-line/subsequent regimens, and 33.4% (95% CI 33.1-35.6 for any ART. PPV, regardless of criteria, for first-line ART patients was lowest among patients over 44 years old and highest for patients aged 15 to 34 years. PPV of immunological and clinical criteria for correctly identifying treatment failure was similarly low for adult patients receiving either first-line or second-line/subsequent ART regimens. Our data confirm the inadequacy of clinical and immunologic criteria to correctly identify treatment failure and support the implementation of routine VL testing.

    A 67-year-old man visited an urological clinic with a chief complaint of urination pain. Cystourethroscopy and magnetic resonance imaging (MRI) examination revealed a bladder tumor (cT3bN0M0). Marked leukocytosis and respiratory distress with pleural effusion appeared. Pulse steroid therapy improved the general condition partially. The patient was sent to our hospital for further examination. Serum granulocyte colony-stimulating factor (G-CSF) and interleukin-6 (IL-6) were high and the pathological findings of bladder tumor obtained by transurethral resection (TUR) revealed an urothelial carcinoma that produced G-CSF and IL-6. Neoadjuvant systemic chemotherapy was performed along with use of steroid and sivelestat, which ameliorated the respiratory distress. After three courses of systemic chemotherapy, serum G-CSF and IL-6 normalized and cystoprostatectomy was performed. The patient has been in good health at 20 months after the surgery with no evidence of recurrence.

    This investigation compared the efficacy of diazepam and the water-soluble prodiazepam-avizafone-in sarin poisoning therapy. Guinea pigs, pretreated with pyridostigmine 0.1 mg/kg, were intoxicated with 4LD(50) of sarin (s.c. route) and 1 min after intoxication treated by intramuscular injection of atropine (3 or 33.8 mg/kg), pralidoxime (32 mg/kg) and either diazepam (2 mg/kg) or avizafone (3.5 mg/kg). EEG and pneumo-physiological parameters were simultaneously recorded. When atropine was administered at a dose of 3 mg/kg, seizures were observed in 87.5% of the cases; if an anticonvulsant was added (diazepam (2 mg/kg) or avizafone (3.5 mg/kg)), seizure was prevented but respiratory disorders were observed. At 33.8 mg/kg, atropine markedly increased the seizure threshold and prevented early respiratory distress induced by sarin. When diazepam was administered together with atropine, seizures were not observed but 62.5% of the animals displayed respiratory difficulties. These symptoms were not observed when using avizafone. The pharmacokinetic data showed marked variation of the plasma levels of atropine and diazepam in different antidote combination groups, where groups receiving diazepam exhibited the lowest concentration of atropine in plasma. Taken together, the results indicate that avizafone is suitable in therapy against sarin when an anticonvulsant is judged necessary.

    2015-01-01

    Full Text Available This study was conducted to evaluate the effects of open endotracheal suctioning on gas exchange and respiratory mechanics in ARF patients under the modes of PCV or VCV. Ninety-six ARF patients were treated with open endotracheal suctioning and their variations in respiratory mechanics and gas exchange after the suctions were compared. Under PCV mode, compared with the initial level of tidal volume (VT, ARF patients showed 30.0% and 27.8% decrease at 1 min and 10 min, respectively. Furthermore, the initial respiratory system compliance (Crs decreased by 29.6% and 28.5% at 1 min and 10 min, respectively. Under VCV mode, compared with the initial level, 38.6% and 37.5% increase in peak airway pressure (PAP were found at 1 min and 10 min, respectively. Under PCV mode, the initial PaO2 increased by 6.4% and 10.2 % at 3 min and 10 min, respectively, while 18.9% and 30.6% increase of the initial PaO2 were observed under VCV mode. Summarily, endotracheal suctioning may impair gas exchange and decrease lung compliance in ARF patients receiving mechanical ventilation under both PCV and VCV modes, but endotracheal suctioning effects on gas exchange were more severe and longer-lasting under PCV mode than VCV.

    Background:There has been no external validation of survival prediction models for severe adult respiratory distress syndrome (ARDS) with extracorporeal membrane oxygenation (ECMO) therapy in China.The aim of study was to compare the performance of multiple models recently developed for patients with ARDS undergoing ECMO based on Chinese single-center data.Methods:A retrospective case study was performed,including twenty-three severe ARDS patients who received ECMO from January 2009 to July 2015.The PRESERVE (Predicting death for severe ARDS on VV-ECMO),ECMOnet,Respiratory Extracorporeal Membrane Oxygenation Survival Prediction (RESP) score,a center-specific model developed for inter-hospital transfers receiving ECMO,and the classical risk-prediction scores of Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ and Sequential Organ Failure Assessment (SOFA) were calculated.In-hospital and six-month mortality were regarded as the endpoints and model performance was evaluated by comparing the area under the receiver operating characteristic curve (AUC).Results:The RESP and APACHE Ⅱ scores showed excellent discriminate performance in predicting survival with AUC of 0.835 (95% confidence interval [CI],0.659-1.010,P =0.007) and 0.762 (95% CI,0.558-0.965,P =0.035),respectively.The optimal cutoff values were risk class 3.5 for RESP and 35.5 for APACHE Ⅱ score,and both showed 70.0% sensitivity and 84.6% specificity.The excellent performance of these models was also evident for the pneumonia etiological subgroup,for which the SOFA score was also shown to be predictive,with an AUC of 0.790 (95% CI,0.571-1.009,P =0.038).However,the ECMOnet and the score developed for externally retrieved ECMO patients failed to demonstrate significant discriminate power for the overall cohort.The PRESERVE model was unable to be evaluated fully since only one patient died six months postdischarge.Conclusions:The RESP,APCHAE Ⅱ,and SOFA scorings systems show good

    Full Text Available Patients with severe acute respiratory distress syndrome (ARDS is an acute diffuse, inflammatory lung injury, leading to increased pulmonary vascular permeability with hypoxemia and bilateral radiographic opacities, associated with decreased lung compliance. Extracorporeal membrane oxygenation (ECMO has been used to support primary or secondary diseases causing respiratory or cardiac failures in newborns, children and adults. Patients with severe ARDS are candidates for ECMO therapy. ECMO is a support modality, not a treatment; it is only beneficial in patients whose primary disease is reversible. ECMO complications-which can lead to mortality, morbidity, long-term disability and reduced quality of life-include surgical and organ bleeding, renal and multi-organ failure and central nervous system problems. The aim of this article was to provide a general overview of ECMO use and outcomes patients with severe acute respiratory distress syndrom.

    The independent risk factors to predict mortality of critical severe acute respiratory syndrome (SARS) were investigated. One hundred and two patients diagnosed with critical SARS were admitted to hospitals of Shanxi Province, from March 7, 2003 to June 4, 2003. The patients were prospectively studied after admission to access their short term outcomes and the risk factors associated with adverse outcomes, defined as death. All the demographic and clinical characteristics were studied and univariate and multivariate Logistic regression were employed to access the risk factors.The results showed that of the 102 cases, 23 patients died, with a crude mortality rate of 22.5%.Multivariate Logistic regression revealed that age above 50 [odds ratio (OR) 1.10, 95 % confidence internal (CI) 1.03 to 1. 16, P=0. 004], lymphopenia at early stage (OR 14.62, 95 % CI 1.78 to 11.97, P= 0.01) were independently associated with mortality. On the other side, psychotherapy (OR 0.01, 95 % CI 0.00 to 0.06, P<0.001) was independently associated with aliveness. It was concluded that critical SARS is a new disease entity that carries significant mortality and morbidity. Specific clinical and laboratory parameters predicting unfavorable and favorable outcomes have been identified.

    OBJECT In patients with hydrocephalus and shunts, lasting symptoms such as headache and dizziness may be indicative of shunt failure, which may necessitate shunt revision. In cases of doubt, the authors monitor intracranial pressure (ICP) to determine the presence of over- or underdrainage of CSF to tailor management. In this study, the authors reviewed their experience of ICP monitoring in shunt failure. The aims of the study were to identify the complications and impact of ICP monitoring, as well as to determine the mean ICP and characteristics of the cardiac-induced ICP waves in pediatric versus adult over- and underdrainage. METHODS The study population included all pediatric and adult patients with hydrocephalus and shunts undergoing diagnostic ICP monitoring for tentative shunt failure during the 10-year period from 2002 to 2011. The patients were allocated into 3 groups depending on how they were managed following ICP monitoring: no drainage failure, overdrainage, or underdrainage. While patients with no drainage failure were managed conservatively without further actions, over- or underdrainage cases were managed with shunt revision or shunt valve adjustment. The ICP and ICP wave scores were determined from the continuous ICP waveforms. RESULTS The study population included 71 pediatric and 75 adult patients. There were no major complications related to ICP monitoring, but 1 patient was treated for a postoperative superficial wound infection and another experienced a minor bleed at the tip of the ICP sensor. Following ICP monitoring, shunt revision was performed in 74 (51%) of 146 patients, while valve adjustment was conducted in 17 (12%) and conservative measures without any actions in 55 (38%). Overdrainage was characterized by a higher percentage of episodes with negative mean ICP less than -5 to -10 mm Hg. The ICP wave scores, in particular the mean ICP wave amplitude (MWA), best differentiated underdrainage. Neither mean ICP nor MWA levels showed any

    Full Text Available Este é um relato de caso de exposição ocupacional a conservantes de alimentos que resultou em insuficiência respiratória aguda em três trabalhadores. A análise toxicológica demonstrou que a mistura dos conservantes, por eles realizada, produziu NO2 que inalado causou quadro compatível com edema pulmonar e insuficiência respiratória aguda. Na evolução, o dano pulmonar regrediu de forma completa nos três indivíduos. Faz-se uma breve revisão sobre dano pulmonar agudo relacionado a exposição ocupacional. Enfatiza-se a importância do treinamento dos trabalhadores que manipulam substâncias químicas bem com da utilização de equipamentos de proteção adequados.Herein, we report an instance of occupational exposure to food preservatives and resultant acute respiratory failure in three workers. The toxicological analysis revealed that mixing the particular food preservatives involved, a procedure that was performed by the three workers involved, produced NO2, the inhalation of which caused the pulmonary edema and respiratory failure. With time, the pulmonary damage was completely reversed in all three individuals. Accompanying this case report is a brief review of the literature regarding acute pulmonary injury resulting from occupational exposure to chemicals. We emphasize the importance of training, as well as of the use of protective gear, for workers who handle chemical substances.

    Hereditary angioedema (HAE) is a rare autosomal dominant disease most commonly associated with defects in C1 esterase inhibitor (C1-INH). HAE manifests as recurrent episodes of edema in various body locations. Atypical symptoms, such as ascites, acute respiratory distress syndrome, and hypovolemic shock, have also been reported. Management of HAE conventionally involves the treatment of acute attacks, as well as short- and long-term prophylaxis. Since attacks can be triggered by several factors, including stress and physical trauma, prophylactic therapy is recommended for patients undergoing surgery. Human plasma-derived C1-INH (pdC1-INH) concentrate is indicated for the treatment of both acute HAE attacks and pre-procedure prevention of HAE episodes in patients undergoing medical, dental, or surgical procedures. We report the first case of a patient with HAE who experienced an abdominal attack precipitated by a retroperitoneal bleed while being converted from warfarin to heparin in preparation for surgery. Subsequently, the patient had a protracted course in hospital with other complications, which included hypovolemic shock, ascites, severe sepsis from nosocomial pneumonia, renal and respiratory failure. Despite intensive interventions, the patient remained in a critical state for months; however, after a trial of daily intravenous infusion of pdC1-INH concentrate (Berinert®, CSL Behring GmbH, Marburg, Germany), clinical status improved, particularly renal function. Therefore, pdC1-INH concentrate may be an effective treatment option to consider for critically-ill patients with HAE.

    Full Text Available BACKGROUND: Heart failure as recognized and treated in typical practice may represent a complex condition that defies discrete categorizations. To illuminate this complexity, we examined treatment strategies for patients hospitalized and treated for decompensated heart failure. We focused on the receipt of medications appropriate for other acute conditions associated with shortness of breath including acute asthma, pneumonia, and exacerbated chronic obstructive pulmonary disease. METHODS AND RESULTS: Using Premier Perspective(®, we studied adults hospitalized with a principal discharge diagnosis of heart failure and evidence of acute heart failure treatment from 2009-2010 at 370 US hospitals. We determined treatment with acute respiratory therapies during the initial 2 days of hospitalization and daily during hospital days 3-5. We also calculated adjusted odds of in-hospital death, admission to the intensive care unit, and late intubation (intubation after hospital day 2. Among 164,494 heart failure hospitalizations, 53% received acute respiratory therapies during the first 2 hospital days: 37% received short-acting inhaled bronchodilators, 33% received antibiotics, and 10% received high-dose corticosteroids. Of these 87,319 hospitalizations, over 60% continued receiving respiratory therapies after hospital day 2. Respiratory treatment was more frequent among the 60,690 hospitalizations with chronic lung disease. Treatment with acute respiratory therapy during the first 2 hospital days was associated with higher adjusted odds of all adverse outcomes. CONCLUSIONS: Acute respiratory therapy is administered to more than half of patients hospitalized with and treated for decompensated heart failure. Heart failure is therefore regularly treated as a broader cardiopulmonary syndrome rather than as a singular cardiac condition.

    Full Text Available Mortality from acute respiratory distress syndrome (ARDS has gone down recently. In spite of this trend, the absolute numbers continue to be high even with improvements in ventilator strategies and a better understanding of fluid management with this disease. A possible reason for this could be an under-recognized involvement of the pulmonary vasculature and the right side of the heart in ARDS. The right heart is not designed to function under situations leading to acute elevations in afterload as seen in ARDS, and hence it decompensates. This brief review focuses on the magnitude of the problem, its detection in the intensive care unit, and recognizes the beneficial effect of prone-positioning on the pulmonary vasculature and right heart.

    The purpose of this study was to compare the efficacy of diazepam and the pro-diazepam avizafone in preventing the severity of soman-induced pathology in guinea pig. Survival, respiration and seizures of experimental animals were investigated with on-line monitoring of respiratory and EEG parameters. Guinea pigs were pretreated with pyridostigmine (0.1mg/kg i.m.) and 30 min later challenged with 1 or 2 LD50 soman. One minute after intoxication they were treated with atropine (3 or 33.8 mg/kg), pralidoxime chloride (32 mg/kg) and either diazepam (2 mg/kg), avizafone (3.5 mg/kg) or saline solution. The highest dose of atropine (33.8 mg/kg) gave a protective effect in groups treated without anticonvulsants by reducing the severity of clinical signs and death within 24 h but also by decreasing seizure occurrence and brain injuries. When injected at the similar molar dose of 7 micromoles/kg, the protection of anticonvulsants against soman neurotoxicity was higher with the atropine/pralidoxime/avizafone combination than with atropine/pralidoxime/diazepam. Indeed, when atropine was used at the lowest dose, avizafone was found to prevent early mortality and seizures occurrence with better efficacy than diazepam. On the other hand, when added to the therapy, the both anticonvulsants did not prevent the moderate EEG depression (reduction of amplitude by 30-52%) observed under 2 LD50 soman. Moreover, the number of animals suffering from respiratory distress (defined as a decrease of minute ventilation of more than 20% from the baseline value) was enhanced when diazepam or avizafone were used in the therapy. This effect was dependent on the atropine dose and the nature of the anticonvulsant. The beneficial effects of the different therapeutics tested were assessed and compared to the previous data obtained with the same therapies against sarin and from the pharmacokinetics properties of the atropine/diazepam mixture.

    Conclusion: PJK and failure are well-recognized suboptimal outcomes of long-segmental fusions of the thoracolumbar spine that can lead to significant neurological morbidity and costly revision surgeries. With no known proximal junction failures to date, the MLSS technique has shown promising results in preventing adverse proximal junctional conditions and can be safely performed under fluoroscopy guidance. Future direction includes a comparative study establishing the relative risk of developing PJK with this novel technique versus a traditional long-segmental thoracolumbar fusion.

    Definition of Respiratory Failure using PaO2 alone is confounded when patients are commenced on oxygen therapy prior to arterial blood gas (ABG) measurement. Furthermore, classification of Respiratory Failure as Type 1 or Type 2 using PaCO2 alone can give an inaccurate account of events as both types can co-exist. 100 consecutive presentations of acute respiratory distress were assessed initially using PaO2, and subsequently PaO2\\/FiO2 ratio, to diagnose Respiratory Failure. Respiratory Failure cases were classified as Type 1 or Type 2 initially using PaCO2, and subsequently alveolar-arterial (A-a) gradient. Any resultant change in management was documented. Of 100 presentations, an additional 16 cases were diagnosed as Respiratory Failure using PaO2\\/FiO2 ratio in place of PaO2 alone (p = 0.0338). Of 57 cases of Respiratory Failure, 22 cases classified as Type 2 using PaCO2 alone were reclassified as Type 1 using A-a gradient (p < 0.001). Of these 22 cases, management changed in 18.

    This book thoroughly covers each subfield of respiratory mechanics: pulmonary mechanics, the respiratory pump, and flow. It presents the current understanding of the field and serves as a guide to the scientific literature from the golden age of respiratory mechanics, 1960 - 2010. Specific topics covered include the contributions of surface tension and tissue forces to lung recoil, the gravitational deformation of the lung, and the interdependence forces that act on pulmonary airways and blood vessels. The geometry and kinematics of the ribs is also covered in detail, as well as the respiratory action of the external and internal intercostal muscles, the mechanics of the diaphragm, and the quantitative compartmental models of the chest wall is also described. Additionally, flow in the airways is covered thoroughly, including the wave-speed and viscous expiratory flow-limiting mechanisms; convection, diffusion and the stationary front; and the distribution of ventilation. This is an ideal book for respiratory ...

    To determine if age-associated vascular dysfunction in older adults with heart failure (HF) is due to insufficient synthesis of nitric oxide (NO), we performed two separate studies: 1) a kinetic study with a stable isotope tracer method to determine in vivo kinetics of NO metabolism, and 2) a vascular function study using a plethysmography method to determine reactive hyperemic forearm blood flow (RH-FBF) in older and young adults in the fasted state and in response to citrulline ingestion. In the fasted state, NO synthesis (per kg body wt) was ∼ 50% lower in older vs. young adults and was related to a decreased rate of appearance of the NO precursor arginine. Citrulline ingestion (3 g) stimulated de novo arginine synthesis in both older [6.88 ± 0.83 to 35.40 ± 4.90 μmol · kg body wt(-1) · h(-1)] and to a greater extent in young adults (12.02 ± 1.01 to 66.26 ± 4.79 μmol · kg body wt(-1) · h(-1)). NO synthesis rate increased correspondingly in older (0.17 ± 0.01 to 2.12 ± 0.36 μmol · kg body wt(-1) · h(-1)) and to a greater extent in young adults (0.36 ± 0.04 to 3.57 ± 0.47 μmol · kg body wt(-1) · h(-1)). Consistent with the kinetic data, RH-FBF in the fasted state was ∼ 40% reduced in older vs. young adults. However, citrulline ingestion (10 g) failed to increase RH-FBF in either older or young adults. In conclusion, citrulline ingestion improved impaired NO synthesis in older HF adults but not RH-FBF, suggesting that factors other than NO synthesis play a role in the impaired RH-FBF in older HF adults, and/or it may require a longer duration of supplementation to be effective in improving RH-FBF.

    X-linked agammaglobulinemia (XLA) is caused by mutation in the gene coding for Bruton’s tyrosine kinase (BTK), which impairs peripheral B cell maturation and hypogammaglobulinemia. In this report, we present a case of XLA in a 22-year-old adult male. Genetic testing revealed a novel mutation located at the conserved region (c.383T>C). The patient had a history of recurrent respiratory tract infection which eventually progressed to chronic type II respiratory failure. Several pathogenic bacteria were isolated on culture of respiratory secretions obtained on bronchoscopy. The patient improved on treatment with antibiotics. PMID:27867589

    Full Text Available Lung function abnormalities both at rest and during exercise are frequently observed in patients with chronic heart failure, also in the absence of respiratory disease. Alterations of respiratory mechanics and of gas exchange capacity are strictly related to heart failure. Severe heart failure patients often show a restrictive respiratory pattern, secondary to heart enlargement and increased lung fluids, and impairment of alveolar-capillary gas diffusion, mainly due to an increased resistance to molecular diffusion across the alveolar capillary membrane. Reduced gas diffusion contributes to exercise intolerance and to a worse prognosis. Cardiopulmonary exercise test is considered the “gold standard” when studying the cardiovascular, pulmonary, and metabolic adaptations to exercise in cardiac patients. During exercise, hyperventilation and consequent reduction of ventilation efficiency are often observed in heart failure patients, resulting in an increased slope of ventilation/carbon dioxide (VE/VCO2 relationship. Ventilatory efficiency is as strong prognostic and an important stratification marker. This paper describes the pulmonary abnormalities at rest and during exercise in the patients with heart failure, highlighting the principal diagnostic tools for evaluation of lungs function, the possible pharmacological interventions, and the parameters that could be useful in prognostic assessment of heart failure patients.

    Objective To evaluate the clinical efficacy of sequential invasive-noninvasive mechanical ventilation ( SINMV) in treatment of surgical acute respiratory failure ( ARF). Methods One hundred and twenty six ARF patients due to surgery diseases were admitted in intensive care unit (ICU) and underwent tracheal intubation and invasive mechanical ventilation (MV) from October 2010 to November 2011; the patients were randomly divided into two groups with 63 cases in each. When the switch point was achieved, patients in sequential group accepted noninvasive MV and intubations were removed. Those in routine group continually accepted invasive MV and disconnect MV with routine mode. Results There were no significant differences in APACHE II scores, respiratory rate, heart rate, mean arterial blood pressure, pH of arterial blood and oxygenation index between the two groups (all P >0.05). The incidence of ventilation associated pneumonia (VAP) in sequential and routine groups was 15. 9% and 42. 9% , respectively (^2 = 17. 387 , P <0. 001). The duration of invasive MV was (8 ±3) d and (24 ± 12) d; the total duration of MV was (16 ±6) d and (24 ± 12) d, and duration of ICU stay was (17 ± 5) d and (26 ± 11) d, respectively (t = 9. 673, 8. 896 and 6. 879, respectively, all P < 0. 001). Conclusion Compared with routine MV, SNIMV may decrease the prevalence of VAP and shorten the duration of invasive MV, total MV and ICU stay in the patients with ARF due to surgery diseases.%目的 评价有创-无创序贯性机械通气治疗外科急性呼吸衰竭(acute respiratory failure,ARF)的临床效果.方法 以2010年10月至2011年11月收住我院ICU的126例外科ARF行气管插管和机械通气者为研究对象,前瞻性随机分为两组,每组63例.达到序贯切换点后,序贯组拔除气管插管,应用无创机械通气支持直至脱机;常规组则继续有创机械通气,以常规方式脱机.结果 两组患者在治疗前,APACHEⅡ评分、呼吸频率、心

    Alagille syndrome (AS) is an autosomal-dominant, multisystem disorder affecting the liver, heart, eyes, skeleton, and face. The manifestations are predominantly pediatric. Diagnosis is based on findings of a paucity of bile ducts on liver biopsy combined with ≥3 of 5 major clinical criteria. Orthotopic liver transplantation (OLT) is the only option for treating patients who developed liver failure, portal hypertension, severe itching, and xanthomatosis. It is difficult to establish clear criteria for OLT; indications are controversial because of the wide variety of clinical symptoms and the multisystem involvement. Generally, AS-associated liver disease is never an acute illness. We report the case of a 28-year-old woman with AS who underwent urgent OLT for acute liver failure. At 24 months posttransplant, the patient is in good clinical condition and with normal hepatic and renal function.

    Cardiomyopathy secondary to toxic shock syndrome (TSS) is an uncommon but potentially life-threatening problem. We report the case of a 51-year-old male who presented with profound cardiogenic shock and multiorgan failure that could not be managed by conventional therapy with intravenous fluids, vasopressors and inotropes. Venoarterial extracorporeal membrane oxygenation (VA ECMO) was instituted as a bridge to recovery. After administration of antibiotics and intravenous immunoglobulin, the patient's condition improved and he was successfully weaned off ECMO after 6 days. The patient recovered from multiorgan failure, and left ventricular ejection fraction improved from <10% pre-ECMO to 65% 8 months after discharge. This case supports the view that VA ECMO can be used successfully to support vital organ perfusion in patients with profound but reversible cardiomyopathy attributed to TSS.

    Dental treatment is usually conducted in the oral cavity and in very close proximity to the upper respiratory airway. The possibility of unintentionally compromising this airway is high in the dental environment. The accumulation of fluid (water or blood) near to the upper respiratory airway or the loosening of teeth fragmentations and fallen dental instruments can occur. Also, some of the drugs prescribed in the dental practice are central nervous system depressants and some are direct respiratory drive depressors. For this reason, awareness of the respiratory status of the dental patient is of paramount importance. This article focuses on several of the more common causes of respiratory distress, including airway obstruction, hyperventilation, asthma, bronchospasm, pulmonary edema, pulmonary embolism and cardiac insufficiency. The common denominator to all these conditions described here is that in most instances the patient is conscious. Therefore, on the one hand, valuable information can be retrieved from the patient making diagnosis easier than when the patient is unconscious. On the other hand, the conscious patient is under extreme apprehension and stress under such situations. Respiratory depression which occurs during conscious sedation or following narcotic analgesic medication will not be dealt with in this article. Advanced pain and anxiety control techniques such as conscious sedation and general anesthesia should be confined only to operators who undergo special extended training.

To compare different scores and scales used to evaluate mortality in patients with trauma and adult respiratory distress syndrome (ARDS. Material and methods. The clinical charts of 80 adult patients, 70 men and 10 women, who were admitted during the period from January 1st, 1990, to December 31st, 1993, to the Hospital Guillermo Barroso C., Cruz Roja Mexicana in Mexico City with trauma and ARDS, were revised. The following data were evaluated: sex, age, injury-producing mechanisms, associated morbid conditions (shock, multiple blood transfusions, long bone fracture, pulmonary contusion and sepsis, ARDS diagnostic criteria, systemic failure, multiple organ failure, injury severity score, Acute Physiology and Chronic Health Evaluation Scoring System, time elapsed to ARDS diagnosis, period of tracheal intubation and stay at the intensive care unit. Results. Of the 80 patients, 26 died (32.5%, 2 women and 24 men. Injury-producing mechanisms were: running over (31.3%, car accidents (27.5%, gunshot wounds (15%, stab wounds (13.7% multiple contusions (7.5% and falls (5%. A highly significant relationship was found between all scores and scales investigated and mortality. In pulmonary contusion and gastrointestinal failure correlation was doubtful; period of tracheal intubation and stay at the intensive care unit showed no correlation to mortality. Conclusions. Adult patients with trauma who develop ARDS showed high probability of death if additional clinical data of shock and consolidation in three or four quadrants of thorax X-rays are present, among other factors.

    Multiple system atrophy (MSA) is an adult onset, incurable neurodegenerative disease, characterized by symptoms of nervous system failure. Occurrence of laryngeal dystonia indicates increased risk of sudden death caused by airway occlusion. We present the case report of 63-year-old patient with history of orthostatic hypotension, parkinsonism, progressive adynamia, and stridor. The patient was admitted to the hospital for diagnosis of orthostatic hypotension. A diagnosis of possible MSA was made. Because of patient's complaints, an X-ray of the hip joint was taken. It revealed femoral neck fracture. Endoprosthesis insertion under general anesthesia was performed. Two days later the patient presented progressive adynamy and respiratory insufficiency. Endotracheal intubation and respiratory support were required followed by extubation and one more intubation. After second extubation, stridor and acute respiratory insufficiency occurred. Urgent tracheostomy was performed. After 13 days in ICU, the patient was discharged to the rehabilitation center.

    Full Text Available BACKGROUND: Antimonials are still being used for visceral leishmaniasis (VL treatment among HIV co-infected patients in East-Africa due to the shortage of alternative safer drugs like liposomal amphotericin B. Besides tolerability, emergence of resistance to antimonials is a major concern. OBJECTIVES: This study was aimed at assessing the clinical outcome of VL-HIV co-infected patients when treated with sodium stibogluconate (SSG. METHODS: Retrospective patient record analysis of VL-HIV co-infected patients treated at a clinical trial site in north-west Ethiopia was done. Patients with parasitologically confirmed VL and HIV co-infection treated with SSG were included. The dose of SSG used was 20 mg Sb5 (pentavalent antimony/kg and maximum of 850 mg Sb5 for 30 days. The clinical outcomes were defined based on the tissue aspiration results as cure or failure, and additionally the safety and mortality rates were computed. RESULTS: The study included 57 patients treated with SSG and by the end of treatment only 43.9% of patients were cured. The parasitological treatment failure and the case fatality rate were 31.6% and 14.0% respectively. SSG was discontinued temporarily or permanently for 12 (21.1% cases due to safety issues. High baseline parasite load (graded more than 4+ was significantly associated with treatment failure (odds ratio = 8.9, 95% confidence interval = .5-51.7. CONCLUSION: SSG is not only unsafe, but also has low effectiveness for VL-HIV patients. Safe and effective alternative medications are very urgently needed. Drug sensitivity surveillance should be introduced in the region.

    Full Text Available BACKGROUND: For settings with limited laboratory capacity, 2013 World Health Organization (WHO guidelines recommend targeted HIV-1 viral load (VL testing to identify virological failure. We previously developed and validated a clinical prediction score (CPS for targeted VL testing, relying on clinical, adherence and laboratory data. While outperforming the WHO failure criteria, it required substantial calculation and review of all previous laboratory tests. In response, we developed four simplified, less error-prone and broadly applicable CPS versions that can be done 'on the spot'. METHODOLOGY/PRINCIPAL: Findings From May 2010 to June 2011, we validated the original CPS in a non-governmental hospital in Phnom Penh, Cambodia applying the CPS to adults on first-line treatment >1 year. Virological failure was defined as a single VL >1000 copies/ml. The four CPSs included CPS1 with 'current CD4 count' instead of %-decline-from-peak CD4; CPS2 with hemoglobin measurements removed; CPS3 having 'decrease in CD4 count below baseline value' removed; CPS4 was purely clinical. Score development relied on the Spiegelhalter/Knill-Jones method. Variables independently associated with virological failure with a likelihood ratio ≥ 1.5 or ≤ 0.67 were retained. CPS performance was evaluated based on the area-under-the-ROC-curve (AUROC and 95% confidence intervals (CI. The CPSs were validated in an independent dataset. A total of 1490 individuals (56.6% female, median age: 38 years (interquartile range (IQR 33-44; median baseline CD4 count: 94 cells/µL (IQR 28-205, median time on antiretroviral therapy 3.6 years (IQR 2.1-5.1, were included. Forty-five 45 (3.0% individuals had virological failure. CPS1 yielded an AUROC of 0.69 (95% CI: 0.62-0.75 in validation, CPS2 an AUROC of 0.68 (95% CI: 0.62-0.74, and CPS3, an AUROC of 0.67 (95% CI: 0.61-0.73. The purely clinical CPS4 performed poorly (AUROC-0.59; 95% CI: 0.53-0.65. CONCLUSIONS: Simplified CPSs retained

    The treatment of skeletal anterior open-bite malocclusion requires complex orthodontic planning that considers its multifactorial etiology, treatment limitations, and high relapse rates. This case report illustrates a successful treatment approach for a skeletal high-angle Class II malocclusion in an adult with a severe open bite. The treatment consisted of a high-pull headgear therapy after mini-implants failure during fixed orthodontic therapy. Adequate esthetics and function were achieved. Despite its low probability, the unexpected event of mini-implant loosening during complex treatments should be considered. Therefore, classic orthodontic mechanics should be established, especially when treating patients for whom invasive procedures such as miniplates or orthognathic surgery are not available options.

    Heterozygous mutations in the transcriptional regulator GATA-2 associate with multilineage immunodeficiency, myelodysplastic syndrome (MDS), and acute myeloid leukemia (AML). The majority of these mutations localize in the zinc finger (ZnF) domains, which mediate GATA-2 DNA binding. Deregulated hematopoiesis with GATA-2 mutation frequently develops in adulthood, yet GATA-2 function in the bone marrow remains unresolved. To investigate this, we conditionally deleted the GATA-2 C-terminal ZnF (C-ZnF) coding sequences in adult mice. Upon Gata2 C-ZnF deletion, we observed rapid peripheral cytopenia, bone marrow failure, and decreased c-Kit expression on hematopoietic progenitors. Transplant studies indicated GATA-2 has a cell-autonomous role in bone marrow hematopoiesis. Moreover, myeloid lineage populations were particularly sensitive to Gata2 hemizygosity, while molecular assays indicated GATA-2 regulates c-Kit expression in multilineage progenitor cells. Enforced c-Kit expression in Gata2 C-ZnF-deficient hematopoietic progenitors enhanced myeloid colony activity, suggesting GATA-2 sustains myelopoiesis via a cell intrinsic role involving maintenance of c-Kit expression. Our results provide insight into mechanisms regulating hematopoiesis in bone marrow and may contribute to a better understanding of immunodeficiency and bone marrow failure associated with GATA-2 mutation.

    A growing population experiencing heart failure (100,000 patients/year), combined with a shortage of donor organs (less than 2200 hearts/year), has led to increased and expanded use of mechanical circulatory support (MCS) devices. MCS devices have successfully improved clinical outcomes, which are comparable with heart transplantation and result in better 1-year survival than optimal medical management therapies. The quality of perfusion provided during MCS therapy may play an important role in patient outcomes. Despite demonstrated physiologic benefits of pulsatile perfusion, continued use or development of pulsatile MCS devices has been widely abandoned in favor of continuous flow pumps owing to the large size and adverse risks events in the former class, which pose issues of thrombogenic surfaces, percutaneous lead infection, and durability. Next-generation MCS device development should ideally implement designs that offer the benefits of rotary pump technology while providing the physiologic benefits of pulsatile end-organ perfusion.

    Full Text Available As doenças neuromusculares prejudicam a renovação do ar alveolar e, por esta razão, produzem insuficiência respiratória crônica. A instalação da insuficiência respiratória pode acontecer de modo agudo, como nos traumas, ou ser lenta ou rapidamente progressiva, como na esclerose lateral amiotrófica, distrofias musculares, doença da placa mioneural, etc. O comprometimento da musculatura respiratória prejudica também a eficiência da tosse e, no estado atual da terapêutica disponível no Brasil para estes doentes, pode-se dizer que a morbimortalidade nestes indivíduos está mais associada ao fato de que eles tossem mal do que de que ventilam mal. Nesta revisão, uma breve compilação histórica procura mostrar a evolução das órteses e próteses respiratórias, desde o final do século XIX até agora, com o objetivo de apresentar as opções de máquinas disponíveis para o suporte e substituição da ventilação nas doenças neuromusculares. Além disso, são enfatizados os elementos fundamentais para o diagnóstico da hipoventilação alveolar e da falência do mecanismo protetor da tosse: história clínica, determinação do pico de fluxo da tosse, medida da pressão expiratória máxima e da pressão inspiratória máxima, espirometria em dois decúbitos (sentado e supino, oximetria de pulso, capnografia e polissonografia. São apresentados os valores limites disponíveis na literatura tanto para a indicação do suporte noturno da ventilação como para a extensão do suporte para o período diurno. As manobras para incremento da eficiência da tosse são aqui também discutidas, assim como o momento adequado para sua introdução.Neuromuscular diseases affect alveolar air exchange and therefore cause chronic respiratory failure. The onset of respiratory failure can be acute, as in traumas, or progressive (slow or rapid, as in amyotrophic lateral sclerosis, muscular dystrophies, diseases of the myoneural junction, etc

    Full Text Available Background. With 214 million cases and 438,000 deaths in 2015, malaria remains one of the deadliest infectious diseases in tropical countries. Several species of the protozoan Plasmodium cause malaria. However, almost all the fatalities are due to Plasmodium falciparum, a species responsible for the severest cases including cerebral malaria. Immune response to Plasmodium falciparum infection is mediated by the production of pro-inflammatory cytokines, chemokines and growth factors whose actions are crucial for the control of the parasites. Following this response, the induction of anti-inflammatory immune mediators downregulates the inflammation thus preventing its adverse effects such as damages to various organs and death. Methods. We performed a retrospective, nonprobability sampling study using clinical data and sera samples from patients, mainly adults, suffering of non-cerebral or cerebral malaria in Dakar, Sénégal. Healthy individuals residing in the same area were included as controls. We measured the serum levels of 29 biomarkers including growth factors, chemokines, inflammatory and anti-inflammatory cytokines. Results. We found an induction of both pro- and anti-inflammatory immune mediators during malaria. The levels of pro-inflammatory biomarkers were higher in the cerebral malaria than in the non-cerebral malaria patients. In contrast, the concentrations of anti-inflammatory cytokines were comparable in these two groups or lower in CM patients. Additionally, four pro-inflammatory biomarkers were significantly increased in the deceased of cerebral malaria compared to the survivors. Regarding organ damage, kidney failure was significantly associated with death in adults suffering of cerebral malaria. Conclusions. Our results suggest that a poorly controlled inflammatory response determines a bad outcome in African adults suffering of cerebral malaria.
