background: using of natural and synthetic surfactant is a rescue treatment for respiratory distress syndrome. in iran, survanta and curosurf are the most frequent used natural surfactant preparations. we compared the clinical response and safety of two surfactants poractant alpha (curosurf) and beractant (survanta) for treatment of respiratory distress syndrome (rds) in preterm infants. method...

INTRODUCTION There are some patients with severe respiratory disturbances like adult respiratory distress syndrome (ARDS) and suspicion of brain death, for whom typical performance of the apneic test is difficult to complete because of quick desaturation and rapid deterioration without effective ventilation. To avoid failure of brain death confirmation and possible loss of organ donation anothe...

BACKGROUND The literature offers discrepant findings regarding age at death in individuals with Huntington disease (HD). OBJECTIVE To study the age at death and causes of death in males and females with a diagnosis of HD in Norway. METHODS Registry study of deaths in 1986-2015 using data from two national registries: the Norwegian Cause of Death Registry (NCDR) and the registry of the Centr...

The objective of this study was to explore the causes of death in Chinese patients with multiple system atrophy (MSA) as well as differences in the cause of death according to sex, subtype, disease onset, and whether the disease was accompanied by nocturnal stridor. A total of 131 MSA patients were enrolled and followed up once every year until their deaths. Clinical information was collected b...

background: improving the neonatal health and reducing the neonatal mortality rate is valuable for not only health reasons, but social, psychological and economic reasons. it has advantages not just for the neonatal period of life but for the whole life. unfortunately in iran, in spite of efforts, there has been little success in decreasing the neonatal mortality rate. since investigating the c...

BACKGROUND The effectiveness of influenza vaccination against hospitalization and death can only ethically be assessed in observational studies. A concern is that individuals who are vaccinated are healthier than individuals who are not vaccinated, potentially biasing estimates of effectiveness upward. METHODS We conducted a historical cohort study of individuals >64 years of age, for whom th...

West Nile virus (WNV) disease can be fatal for high-risk patients. Since WNV or its antigens have been identified in multiple anatomical locations of the central nervous system of persons or rodent models, one cannot know where to investigate the actual mechanism of mortality without careful studies in animal models. In this study, depressed respiratory functions measured by plethysmography cor...

Respiratory tract infections represent the main cause of death from infectious diseases worldwide. SARS-CoV-2 infection (i.e. COVID-19) added to existing global burden respiratory infections, including tuberculosis. Among nanomaterials for fabric functionalization, graphene, in combination with hydrophobic molecules such as phytochemicals, represents a promising low-cost alternative antibiotics...
