Genetic susceptibility to angiotensin-converting enzyme-inhibitor induced angioedema: A systematic review and evaluation of methodological approaches.

Angiotensin-converting enzyme (ACE) converts angiotensin I to angiotensin II which causes vasoconstriction. ACE inhibitors reduce blood pressure by inhibiting ACE. A well-known adverse drug reaction to ACE inhibitors is ACE inhibitor-induced angioedema (ACEi-AE). Angioedema is a swelling of skin and mucosa, which can be fatal if the airway is compromised. We have performed a systematic review of the evidence suggesting that genetic polymorphisms are associated with ACEi-AE and evaluated the methodological approaches of the included studies. The Cochrane Database of Systematic Reviews, Google Scholar, and PubMed were searched. Studies investigating the association between genetic markers and…

ShRNA-mediated knock-down of CXCL8 inhibits tumor growth in colorectal liver metastasis.

CXCL8 belongs to proinflammatory chemokines that are predominantly involved in neutrophil chemotaxis and degranulation. Several studies have suggested that secretion of CXCL8 from cancer cells have a profound effect on tumor microenvironment. In this study, in continuation to our previous work of understanding the global picture of invasion related genes in colorectal liver metastases, we clearly show an up-regulation of CXCL8 expression in the tumor cells at the invasion front as compared to the tumor cells in the inner parts of the tumor. Furthermore, ShRNA mediated down-regulation of CXCL8 resulted in inhibition of cell proliferation, viability and invasion in vitro and a near complete g…

Low Frequency of Viral Respiratory Tract Infections During Family-Centered Neonatal Intensive Care: Results of a Prospective Surveillance Study

Background: Viral respiratory tract infections (VRTI) may cause severe respiratory and sepsis-like symptoms in infants hospitalized in the neonatal intensive care unit (NICU). Little is known about the frequencies of VRTI in relation to visiting policies in the NICU. Objective: Aim of this study was to evaluate the frequency of symptomatic and asymptomatic VRTI in our family-centered NICU. Methods: This was a 12-month, prospective, observational study from February 2018 to January 2019. Infants hospitalized ≥72 h were eligible for the study. To determine the frequency of VRTI, multiplexed point-of-care testing (mPOCT) of symptomatic infants was combined with a weekly screening of all infant…

Adverse Events and Unsuccessful Intubation Attempts Are Frequent During Neonatal Nasotracheal Intubations.

Background: Intubation of neonates is difficult and hazardous. Factors associated with procedure-related adverse events and unsuccessful intubation attempts are insufficiently evaluated, especially during neonatal nasotracheal intubations.Objective: Aim of this study was to determine the frequency of tracheal intubation–associated events (TIAEs) during neonatal nasotracheal intubations and to identify factors associated with TIAEs and unsuccessful intubation attempts in our neonatal unit.Methods: This was a prospective, single-site, observational study from May 2017 to November 2019, performed at a tertiary care neonatal intensive care unit in a German academic teaching hospital. All endotr…

Prescription patterns of angiotensin-converting enzyme inhibitors for various indications: A UK population-based study

AIM: Angiotensin‐converting enzyme inhibitors (ACEIs) are widely prescribed for several cardiovascular indications. This study investigated patterns of ACEI use for various indications. METHODS: A descriptive, retrospective population‐based study was conducted using data from the UK Clinical Practice Research Datalink. Patients starting ACEIs (2007–2014) were selected and ACEI indications were retrieved from electronically recorded medical records. Stratified by indication, we distinguished between persistent and nonpersistent ACEI use, considering a 6‐month interval between two prescription periods as a maximum for persistent use. Five‐year persistence rates for various indications were ca…

Age-sex specific pulmonary embolism-related mortality in the USA and Canada, 2000-18: an analysis of the WHO Mortality Database and of the CDC Multiple Cause of Death database

Contains fulltext : 232738.pdf (Publisher’s version ) (Closed access) BACKGROUND: Pulmonary embolism (PE)-related mortality is decreasing in Europe. However, time trends in the USA and Canada remain uncertain because the most recent analyses of PE-related mortality were published in the early 2000s. METHODS: For this retrospective epidemiological study, we accessed medically certified vital registration data from the WHO Mortality Database (USA and Canada, 2000-17) and the Multiple Cause of Death database produced by the Division of Vital Statistics of the US Centers for Disease Control and Prevention (CDC; US, 2000-18). We investigated contemporary time trends in PE-related mortality in th…

Trends in mortality related to pulmonary embolism in the European Region, 2000-15: analysis of vital registration data from the WHO Mortality Database

Summary Background European estimates of the burden imposed by pulmonary embolism are not available to this date. We aimed to assess pulmonary embolism-related mortality and time trends in the WHO European Region. Methods We analysed vital registration data from the WHO Mortality Database (2000–15) covering subregions of the WHO European Region: Eastern Europe, Northern Europe, Southern Europe, Western Europe, and Central Asia. Deaths were considered pulmonary embolism-related if International Classification of Disease-10 code for acute pulmonary embolism (I26) or any code for deep or superficial vein thrombosis was listed as the primary cause of death. We used locally estimated scatterplot…

Prognostic value of right ventricular dysfunction or elevated cardiac biomarkers in patients with low-risk pulmonary embolism: a systematic review and meta-analysis

Abstract Aims Patients with acute pulmonary embolism (PE) classified as low risk by the Pulmonary Embolism Severity Index (PESI), its simplified version (sPESI), or the Hestia criteria may be considered for early discharge. We investigated whether the presence of right ventricular (RV) dysfunction may aggravate the early prognosis of these patients. Methods and results We did a systematic review and meta-analysis of studies including low-risk patients with acute PE to investigate the prognostic value of RV dysfunction. Diagnosis of RV dysfunction was based on echocardiography or computed tomography pulmonary angiography. In addition, we investigated the prognostic value of elevated troponin…
