Background: Systemic stress, inflammation, and hydroelectrolytic and acid‒base abnormalities observed during diabetic ketoacidosis (DKA) can cause changes in the heart and even induce cardiovascular damage. We aimed to evaluate the structure and function of the heart during and after a DKA episode via echocardiography and biomarker assessment.

Methods: We performed a transthoracic echocardiogram (TTE) in subjects with an episode of DKA in the first 4-6 h of treatment.

Article Synopsis
  • Pleural effusion (PE) is commonly found in patients with acute decompensated heart failure (ADHF), but its effect on quality of life (QoL) is not well understood.
  • This study aimed to see if the presence of PE, detected by thoracic ultrasound (TUS), impacts the QoL of ADHF patients with a reduced ejection fraction (≤40%).
  • Results showed that patients with PE had significantly worse QoL scores (average of 40) compared to those without PE (average of 12), suggesting a strong link between the amount of pleural fluid and poorer QoL perceptions.

Detergents are highly produced pollutants with environmental problems like foam generation and toxic effects in biota. Nonylphenol ethoxylates (NPEs) are efficient, economical, and versatile surfactants, used in detergents for more than 40 years due to their detergency capacity. In the environment, NPE biodegrades into the metabolite nonylphenol (NP), classified as an endocrine disruptor.

Atorvastatin is widely recommended for long-term secondary prevention in STEMI patients with no contraindication. Although high-dose atorvastatin has been shown to reduce important patient outcomes such as MACE, there is still doubt that high-dose atorvastatin could have the same protective effect in patients undergoing PCI in the short and long term. We searched the following electronic databases: Scopus, Web of Science, MEDLINE, EMBASE, and Cochrane Central considering studies that enrolled adult patients with a confirmed diagnosis of STEMI or NSTEMI undergoing PCI.

Humanitarian crises can occur in places affected by chemical, physical, biological, and social threats, especially when these threats interact with each other and cause a syndemic. In order to avoid crises in these places, it is necessary to introduce mitigation measures that we have framed as "humanitarian scenarios". Due to their nature, implementation of these interventions requires the creation of multidisciplinary operational groups with a work strategy that integrates them into the affected community.
