Thoracentesis and tube thoracostomy are common procedures with bleeding risks, but existing guidelines may be overly conservative. We reviewed the evidence on the safety of thoracentesis and tube thoracostomy in patients with uncorrected coagulopathy.

Is it safe to perform thoracentesis and tube thoracostomy in patients with uncorrected coagulopathy?

This systematic review was performed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. PubMed and Embase were searched from inception through December 31, 2019. Included studies involved patients with uncorrected coagulopathy because of disease (eg, thrombocytopenia, liver cirrhosis, kidney failure) or drugs (eg, antiplatelets, anticoagulants). Relevant outcomes were major bleeding and mortality.

Eighteen studies (5,134 procedures) were included. https://www.selleckchem.com/products/oxiglutatione.html Using random-effects meta-analysis, the pooled major bleeding and mortality rate was 0 (95%CI, 0%-1%). No publication bias was found. Excluding six studies that were in abstract form, meta-analysis of the remaining 12 full articles showed that the pooled major bleeding and mortality rate also was 0 (95%CI, 0%-2%). Subgroup analysis performed for patients with uncorrected coagulopathy resulting from disease or drugs showed similar results.

Among patients with uncorrected coagulopathy who underwent thoracentesis or tube thoracostomy, major bleeding and mortality complications were uncommon. Our results suggest that in appropriately selected patients, thoracentesis or tube thoracostomy can be performed safely.

The benefits of early antibiotics for sepsis have recently been questioned. Evidence for this mainly comes from observational studies. The only randomized trial on this subject, the Prehospital Antibiotics Against Sepsis (PHANTASi) trial, did not find significant mortality benefits from early antibiotics. That subgroups of patients benefit from this practice is still plausible, given the heterogeneous nature of sepsis.

Do subgroups of sepsis patients experience 28-day mortality benefits from early administration of antibiotics in a prehospital setting? And what key traits drive these benefits?

We used machine learning to conduct exploratory partitioning cluster analysis to identify possible subgroups of sepsis patients who may benefit from early antibiotics. We further tested the influence of several traits within these subgroups, using a logistic regression model.

We found a significant interaction between age and benefits of early antibiotics (P= .03). When we adjusted for this interaction and several other confounders, there was a significant benefit of early antibiotic treatment (OR= 0.07; 95%CI= 0.01-0.79; P= .03).

An interaction between age and benefits of early antibiotics for sepsis has not been reported before. When validated, it can have major implications for clinical practice. This new insight into benefits of early antibiotic treatment for younger sepsis patients may enable more effective care.

Hypoxemia is a cardinal feature of fibrotic interstitial lung disease (ILD). The incidence, progression, and prognostic significance of hypoxemia in patients with fibrotic ILD currently is unknown.

What are the epidemiologic features of hypoxemia and its additive prognostic value in a current risk prediction model of fibrotic ILD?

We identified 848 patients with fibrotic ILD (258 with idiopathic pulmonary fibrosis [IPF]) in five prospective ILD registries from Australia, Canada, and Switzerland. Cumulative incidence of exertional and resting hypoxemia from the time of diagnosis was estimated at 1-year intervals in patients with baseline 6-min walk tests, adjusted for competing risks of death and lung transplantation. Likelihood ratio tests were used to determine the prognostic significance of exertional and resting hypoxemia for 1-year mortality or transplantation when added to the ILD GAP model. The cohort was divided into derivation and validation subsets to evaluate performance characteristics of thexemia than patients without IPF. The extended ILD GAP O2 model provides additional risk stratification for 1-year prognosis in fibrotic ILD.

Cough characteristics vary between patients, and this can impact clinical diagnosis and care. The purpose of part two of this state-of-the-art review is to update the American College of Chest Physicians (CHEST) 2006 guideline on global physiology and pathophysiology of cough.

A review of the literature was conducted using PubMed and MEDLINE databases from 1951 to 2019 using prespecified search terms.

We describe the demographics of typical patients with cough in the clinical setting, including how cough characteristics change across age. We summarize the effect of common clinical conditions impacting cough mechanics and the physical properties of mucus on airway clearance.

This is the second of a two-part update to the 2006 CHEST cough guideline; it complements part one on basic phenomenology of cough by providing an extended clinical picture of cough along with the factors that alter cough mechanics and efficiency in patients. A greater understanding of the physiology and pathophysiology of cough will improve clinical management.

Idiopathic pulmonary fibrosis (IPF) is an interstitial lung disease of unknown origin. A limited number of small studies show an effect of tobacco smoking on risk of IPF, but second-hand smoking risk has not been examined.

Are smoking-related exposures associated with risk of IPF and does interaction between them exist?

We designed a prospective cohort study using UK Biobank data, including 437,453 nonrelated men and women of White ethnic background (40-69 years of age at baseline). We assessed the effect of tobacco smoking-related exposures on risk for IPF using Cox regression adjusted for age, sex, Townsend deprivation index, and home area population density. We also examined potential additive and multiplicative interaction between these exposures. Multiple imputation with chained equations was used to address missing data.

We identified 802 incident IPF cases. We showed an association between smoking status (hazard ratio [HR], 2.12; 95%CI, 1.81-2.47), maternal smoking (HR, 1.38; 95%CI, 1.18-1.62), and smoking in the household (HR, 1.
