Background: Estrogen and progesterone levels undergo changes throughout the menstrual cycle. Existing literature regarding the effect of menstrual phases on cardiovascular and autonomic regulation during central hypovolemia is contradictory.

Aims And Study: This study aims to explore the influence of menstrual phases on cardiovascular and autonomic responses in both resting and during the central hypovolemia induced by lower body negative pressure (LBNP).

The validity of venous ultrasound (V-US) for the diagnosis of deep vein thrombosis (DVT) during spaceflight is unknown and difficult to establish in diagnostic accuracy and diagnostic management studies in this context. We performed a systematic review of the use of V-US in the upper-body venous system in spaceflight to identify microgravity-related changes and the effect of venous interventions to reverse them, and to assess appropriateness of spaceflight V-US with terrestrial standards. An appropriateness tool was developed following expert panel discussions and review of terrestrial diagnostic studies, including criteria relevant to crew experience, in-flight equipment, assessment sites, ultrasound modalities, and DVT diagnosis.

Article Synopsis
  • The study examines the effects of lower body negative pressure (LBNP) on retinal microcirculation, a response that has been largely overlooked in existing literature despite known physiological impacts on larger arteries.
  • Forty-four participants underwent a controlled LBNP protocol while retinal measurements were taken at various time points to assess changes in blood flow in the eyes.
  • The results revealed no significant alterations in retinal microcirculation between the measured time intervals or between male and female participants, indicating that further studies with higher LBNP levels are necessary to explore retinal responses in conditions like hypovolemic shock.

Introduction: Lower body negative pressure (LBNP) eliminates the impact of weight-bearing muscles on venous return, as well as the vestibular component of cardiovascular and autonomic responses. We evaluated the hemodynamic and autonomic responses to central hypovolemia, induced by LBNP in both males and females.

Methodology: A total of 44 participants recruited in the study.

The recent incidental discovery of an asymptomatic venous thrombosis (VT) in the internal jugular vein of an astronaut on the International Space Station prompted a necessary, immediate response from the space medicine community. The European Space Agency formed a topical team to review the pathophysiology, risk and clinical presentation of venous thrombosis and the evaluation of its prevention, diagnosis, mitigation, and management strategies in spaceflight. In this article, we discuss the findings of the ESA VT Topical Team over its 2-year term, report the key gaps as we see them in the above areas which are hindering understanding VT in space.

Although clinical decision support systems (CDSSs) are increasingly emphasized as one of the possible levers for improving care, they are still not widely used due to different barriers, such as doubts about systems' performance, their complexity and poor design, practitioners' lack of time to use them, poor computer skills, reluctance to use them in front of patients, and deficient integration into existing workflows. While several studies on CDSS exist, there is a need for additional high-quality studies using large samples and examining the differences between outcomes following a decision based on CDSS support and those following decisions without this kind of information. Even less is known about the effectiveness of a CDSS that is delivered during a grand round routine and with the help of socially assistive humanoid robots (SAHRs).

Introduction: Population ageing, the rise of chronic diseases and the emergence of new viruses are some of the factors that contribute to an increasing share of gross domestic product dedicated to health spending. COVID-19 has shown that nursing staff represents the critical part of hospitalisation. Technological developments in robotics and artificial intelligence can significantly reduce costs and lead to improvements in many hospital processes.

Background: Symptomatic patients with chronic mesenteric ischemia (CMI) should be treated without much delay because symptoms of CMI are present in 43% patients who present with acute mesenteric ischemia. There are few reported series with large numbers of patients undergoing surgery for CMI, and many controversies persist regarding the optimal surgical treatment. These controversies include the type of surgical repair (antegrade vs.

Secondary aortoenteric fistulas (SAEF) are a relatively rare but dangerous complication of aortal reconstructive surgery. We present a patient that underwent aortobifemoral bypass three years before developing the signs of aortoenteric fistula, and we reviewed the literature on the topic. Since the clinical signs are nonspecific, physicians should have a high index of suspicion for SAEF in patients who underwent aortal reconstructive surgery.
