Anti-Inflammatory and Anti-Oxidant Properties of N-Acetylcysteine: A Fresh Perspective.

N-acetyl-L-cysteine (NAC) was initially introduced as a treatment for mucus reduction and widely used for chronic respiratory conditions associated with mucus overproduction. However, the mechanism of action for NAC extends beyond its mucolytic activity and is complex and multifaceted. Contrary to other mucoactive drugs, NAC has been found to exhibit antioxidant, anti-infective, and anti-inflammatory activity in pre-clinical and clinical reports.

The Relation Between Domestic Violence and Professional, Contact Sports: It's Complicated.

Learning theories provide explanations for domestic violence; they can also aid in our understanding of the relation between contact sports and domestic violence. Notably, language used during sporting events and athletes' behaviors being rewarded both on and off the field can influence the behaviors of viewers. Adubato (2016) found a statistically significant relation between an increase in domestic violence arrests and the kick-off times of Philadelphia Eagles football games.

Early lung diffusion abnormalities and airways' inflammation in children with type 1 diabetes.

Background And Aims Of The Study: Type 1 diabetes (T1D) impacts lung function and exercise capacity in adults, but limited information is available in children. We hypothesize that T1D causes alterations in pulmonary function and cardiorespiratory fitness, i.e.

Acute dyspnea in the emergency department: a clinical review.

Acute dyspnea represents one of the most frequent symptoms leading to emergency room evaluation. Its significant prognostic value warrants a careful evaluation. The differential diagnosis of dyspnea is complex due to the lack of specificity and the loose association between its intensity and the severity of the underlying pathological condition.

Ultrasonographic Assessment of Diaphragmatic Function and Its Clinical Application in the Management of Patients with Acute Respiratory Failure.

Acute respiratory failure (ARF) is a common life-threatening medical condition, with multiple underlying etiologies. In these cases, many factors related to systemic inflammation, prolonged use of steroids, and lung mechanical abnormalities (such as hyperinflation or increased elastic recoil due to pulmonary oedema or fibrosis) may act as synergic mechanisms leading to diaphragm dysfunction. The assessment of diaphragm function with ultrasound has been increasingly investigated in the emergency department and during hospital stay as a valuable tool for providing additional anatomical and functional information in many acute respiratory diseases.

Acute Improvements of Oxygenation with Cpap and Clinical Outcomes in Severe COVID-19 Pneumonia: A Multicenter, Retrospective Study.

It is not known if the degrees of improvement in oxygenation obtained by CPAP can predict clinical outcomes in patients with COVID-19 pneumonia. This was a retrospective study conducted on patients with severe COVID-19 pneumonia treated with CPAP in three University hospitals in Milan, Italy, from March 2020 to March 2021. Arterial gas analysis was obtained before and 1 h after starting CPAP.

Keep on tailoring CMV management in lung transplantation: 24 versus 12-month CMV hyperimmune globulins regimen effects in combined universal prophylaxis.

Background: In lung transplantation (LTx), Cytomegalovirus (CMV) management is based on prophylaxis or pre-emptive therapy. CMV hyperimmune globulins (CMV IG) added to prophylactic antiviral agents reduce CMV manifestations and acute rejection. The length of prophylaxis regimens is variable among studies with different results.

A Positive Versus Negative Interaction Memory Affects Parole Officers' Implicit Associations Between the Self-Concept and the Group Parolees.

Background: Parole officers are one of many actors in the legal system charged with interpreting and enforcing the law. Officers not only assure that parolees under their supervision comply with the terms of their release, but also monitor and control parolees' criminal behavior. They conduct their jobs through their understanding of their official mandate and make considered and deliberate choices while executing that mandate.

A reappraisal of inspiratory capacity in chronic obstructive pulmonary disease: clinical correlates and role of long-acting muscarinic antagonists and long-acting β2 agonists.

Introduction: In patients with chronic obstructive pulmonary disease (COPD), static and dynamic hyperinflation, together with expiratory flow limitation and gas exchange abnormalities, is one of the major causes of dyspnea, decreased exercise performance and ventilatory failure. An increase in functional residual capacity (FRC) is accompanied by a decrease in inspiratory capacity (IC), which is a volume readily available, repeatable, and simple to measure with any spirometer. Changes in IC and FRC after bronchodilation, contrary to changes in FEV, have been closely associated with improvements in dyspnea and exercise performance.

Perioperative Complications and Anesthesia Practices in Managing Patients With Quadriplegia Undergoing Surgery: A Systematic Review.

Quadriplegia is associated with a multitude of health complications affecting numerous organ systems. Complications during the perioperative periods are not uncommon in this patient population due to abnormal responses to surgical stressors. Such complications include autonomic dysreflexia, cardiac ischemia, and respiratory compromise.

The ameliorative effects of cinnamon oil against ethanol-induced gastric ulcer in rats by regulating oxidative stress and promoting angiogenesis.

Cinnamon is one of the herbal resources belonging to the Lauraceae family, is commonly used in traditional medicine and as a flavoring agent. It has antioxidant and anti-inflammatory activities. Therefore, the present study was performed to evaluate the gastroprotective effect of cinnamon on ethanol-induced gastric ulcer in comparison to omeprazole.

Predictors of Helmet CPAP Failure in COVID-19 Pneumonia: A Prospective, Multicenter, and Observational Cohort Study.

Background: Continuous positive airway pressure (CPAP) can be beneficial in acute respiratory failure (ARF) due to coronavirus (COVID-19) pneumonia, but delaying endotracheal intubation (ETI) in nonresponders may increase mortality. We aimed at investigating the performance of composite respiratory indexes as possible predictors of CPAP failure in ARF due to COVID-19.

Methods: This was a multicenter, prospective, observational, and cohort study conducted in the respiratory units of three University hospitals in Milan and in a secondary care hospital in Codogno (Italy), on consecutive adult patients with ARF due to COVID-19 pneumonia that underwent CPAP between March 2020 and March 2021.

A Case Report of Cystic Fibrosis Plus Tuberous Sclerosis: A Cautionary Tale Regarding Lung Transplantation.

Background: Cystic fibrosis (CF) and tuberous sclerosis complex (TSC) are 2 rare genetic diseases that often affect the lungs. Pulmonary compromise in TSC or CF can be severe enough to require lung transplantation. In rare instances patients with CF undergo pneumonectomy to control recurrent lung infections and lung necrosis affecting one lung more than the other.

This was a prospective, observational, physiological, cohort study on consecutive adult patients with COVID-19 pneumonia admitted in April-May 2020 in the high dependency respiratory unit of L. Sacco University Hospital in Milan (Italy).

Ultrasound and non-ultrasound imaging techniques in the assessment of diaphragmatic dysfunction.

Diaphragm muscle dysfunction is increasingly recognized as an important element of several diseases including neuromuscular disease, chronic obstructive pulmonary disease and diaphragm dysfunction in critically ill patients. Functional evaluation of the diaphragm is challenging. Use of volitional maneuvers to test the diaphragm can be limited by patient effort.

The potential use of ABO blood group system for risk stratification of COVID-19.

ABO blood groups is a cheap and affordable test that can be immediately retrieved from COVID-19 patients at the diagnosis. There is increasing evidence that non-O blood groups have both higher susceptibility and higher severity of COVID-19 infections. The reason behind such relationship seems elusive.

Helmet CPAP to Treat Acute Hypoxemic Respiratory Failure in Patients with COVID-19: A Management Strategy Proposal.

Since the beginning of March 2020, the coronavirus disease 2019 (COVID-19) pandemic has caused more than 13,000 deaths in Europe, almost 54% of which has occurred in Italy. The Italian healthcare system is experiencing a stressful burden, especially in terms of intensive care assistance. In fact, the main clinical manifestation of COVID-19 patients is represented by an acute hypoxic respiratory failure secondary to bilateral pulmonary infiltrates, that in many cases, results in an acute respiratory distress syndrome and requires an invasive ventilator support.

The Airways' Mechanical Stress in Lung Disease: Implications for COPD Pathophysiology and Treatment Evaluation.

The airway epithelium stretches and relaxes during the normal respiratory cycle, and hyperventilation exaggerates this effect, resulting in changes in lung physiology. In fact, stretching of the airways influences lung function and the secretion of airway mediators, which in turn may cause a potentially injurious inflammatory response. This aim of the present narrative review was to illustrate the current evidence on the importance of mechanical stress in the pathophysiology of lung diseases with a particular focus on chronic obstructive pulmonary disease (COPD) and to discuss how this may influence pharmacological treatment strategies.
