Article Synopsis
  • * A total of 37 studies were analyzed, with findings showing limited significant negative associations between lung function (measured by FEV1(%)) and anxiety, while a clearer negative association was found with depression.
  • * The review concluded that there is little evidence linking anxiety with lung function impairment, but there is stronger evidence supporting a connection between decreased lung function and increased depression in COPD patients.

Article Synopsis
  • Many COPD patients are diagnosed late, often during their first acute exacerbation (AECOPD), which increases mortality risk.
  • In a study of over 107,000 patients, those diagnosed in primary care were younger, while those identified in hospitals were older, mostly male, and had more comorbidities.
  • Hospital diagnoses were linked to higher one-year mortality rates compared to earlier diagnoses in primary care, emphasizing the importance of timely diagnosis.

Article Synopsis
  • Predicting survival rates of discarded aquatic animals using vitality indicators is more resource-efficient than captive observation, but these indicators can be inaccurate.
  • A new analytical method was developed to optimize predictions for the discard survival of European plaice, taking into account the varying impacts of specific reflexes and injuries.
  • In testing various vitality indicators, all were found to perform poorly in predicting survival rates without considering factors like air exposure and seawater temperature, highlighting the need for better predictive measures.

This paper analyses the transition of Ethereum (ETH) from the energy-intensive Proof-of-Work (PoW) to the less energy-intensive Proof-of-Stake (PoS). We analyze returns, volatility, return correlations and volume of ETH, ETC and Bitcoin for all events in the lead-up to the actual change from PoW to PoS also labelled "the merge." The analysis suggests that some investors value the less energy-intensive mining mechanism and invest in ETH.

Purpose: Breast cancer (BC) treatment may affect pulmonary function, but evidence of long-term pulmonary toxicity is scarce. This study aimed to evaluate pulmonary function, radiation fibrosis (RF), and patient-reported dyspnea up to 12 years after different BC treatment modalities.

Methods And Materials: Two hundred fifty patients with BC referred to postoperative radiotherapy (RT) were included in this study.
