Introduction Y Objectives: Tako-tsubo syndrome (TTS) is a cardiac condition that mimics acute coronary syndrome, characterized by transient left ventricular dysfunction in the absence of culprit coronary artery stenosis. Although its etiology remains unknown, reversible microvascular dysfunction secondary to an adrenergic surge is thought to play a role. Treatment is empirical, although most patients receive beta-blockers (BB) in clinical practice.

Background: The purpose of this study was to evaluate potential predictors of no-shows and late cancellations in an outpatient clinic within a large healthcare system serving vulnerable communities.

Methods: Demographic data and appointment status were recorded for 537 consecutive patients scheduled for neuropsychological evaluation in an outpatient psychiatry clinic. Patients include 220 males and 317 females with an average formal education of 11.

Article Synopsis
  • A study in Sweden analyzed trends in acute Achilles tendon ruptures (ATR) from 2002 to 2021, noting a significant increase in incidence rates alongside a decrease in surgical treatment.
  • Out of 53,688 ATR cases identified, the long-term incidence rate rose by 45%, while the surgical incidence rate dropped from 13.4 to 6.0 per 100,000 person-years.
  • Additionally, the time from injury to surgery (TTS) increased substantially from 0.6 days in 2002 to 5.1 days in 2021, indicating a need for better treatment and rehabilitation strategies for non-surgically treated patients.

Background ST-segment-elevation myocardial infarction complicated with no reflow after primary percutaneous coronary intervention is associated with adverse outcomes. Although several hyperemic drugs have been shown to improve the Thrombolysis in Myocardial Infarction flow, optimal treatment of no reflow remains unsettled. Saline infusion at 20 mL/min via a dedicated microcatheter causes (flow-mediated) hyperemia.

Human space flight poses several challenges to human health, such as microgravity, space radiation, and prolonged confinement. Humans are anatomically and physiologically adapted to the gravitation on earth, and microgravity affects crucial functions. We review the pathophysiological consequences of spaceflight on the sensomotoric, cardiovascular, cerebral, and musculoskeletal systems, as well as effects of space radiation and psychosocial considerations.
