Ventilatory chemosensitivity, cerebral and muscle oxygenation, and total hemoglobin mass before and after a 72-day mt. Everest expedition.
2014
Abstract. Cheung, Stephen S, Niina E. Mutanen, Heikki M. Karinen, Anne S. Koponen, Heikki Kyro ̈ la ̈ inen, Heikki O. Tikkanen, and Juha E. Peltonen. Ventilatory chemosensitivity, cerebral and muscle oxygenation, and total hemoglobin mass before and after a 72-day Mt. Everest expedition. High Alt Med Biol 15:331–340, 2014.— Background: We investigated the effects of chronic hypobaric hypoxic acclimatization, performed over the course of a 72-day self-supported Everest expedition, on ventilatory chemosensitivity, arterial saturation, and tissue oxygenation adaptation along with total hemoglobin mass (tHb-mass) in nine experienced climbers (age 37 – 6 years, _ VO 2peak 55 – 7mL $ kg - 1 $ min…
[Takotsubo cardiomyopathy: a consensus document].
2008
Takotsubo cardiomyopathy is a syndrome characterized by acute regional systolic dysfunction of the left ventricle, frequently related to psycho-physical acute stress, and usually reversible. This rare syndrome involves more often the female sex with the highest frequency of occurrence between the seventh and eighth decade of life. Etiology has not been clarified yet and several hypotheses have been postulated: multiple epicardial coronary artery damage, abnormal coronary microcirculation, catecholamine-mediated cardiac toxicity, and neurogenic stunning. Clinical presentation is not easy to distinguish from an acute coronary syndrome: chest pain at rest or dyspnea, new-onset electrocardiogra…
Alexithymia as a Predictor of Arousal and Affect Dysregulations when Batterers with Attention Deficit Hyperactivity Disorder Cope with Acute Stress
2020
Empirical research has stated that Attention Deficit Hyperactivity Disorder (ADHD) might underlie intimate partner violence against women (IPVAW) perpetration. Even though there is a clear relationship between these two variables, it is still unknown how ADHD facilitates violence proneness. In this regard, psychophysiological variables such as skin conductance levels (SCL) might offer information about emotional regulation when individuals cope with stress. Furthermore, alexithymia traits might be a strong candidate in explaining the above-mentioned emotional dysregulations. Hence, we compared the SCL response to acute cognitive stress in IPVAW perpetrators with and without ADHD symptoms to…

The asthma-COPD overlap syndrome (ACOS): hype or reality? That is, a curiosity for the media or an opportunity for physicians?
2014
Asthma-COPD Overlap Syndrome (ACOS) has been recently defined as a new pathological entity. Most studies support a large difference in the pathophysiology of bronchial asthma and chronic obstructive pulmonary disease (COPD). However, there is evidence of an increasing prevalence of patients in whom the two diseases coexist or in which one condition evolves into the other, leading to the pathological condition named ACOS. This occurs mainly in individuals with long-standing asthma, especially if also current or former-smokers. Indeed, epidemiological studies show that aging is one of the main risk factors for ACOS, creating the basis for the two entities to converge on the same subject. It i…
Lesions to the posterior insular cortex cause dysarthria
2011
Background: Up to now, there are few systematic studies in a sufficient number of patients with lesions involving the insular cortex (IC) examining whether damage of the IC is directly related to dysarthria. Thus, this is the first study applying modern voxel-lesion behaviour mapping (VLBM) aimed to examine whether the IC is involved in dysarthria – and if so – which part of the IC is involved. Methods: Twenty-five patients with acute stroke lesions affecting the IC and peri-insular region were investigated employing VLBM analysis. Results: Present data indicated that dysarthria is associated with stroke lesions affecting the right- and left-sided posterior IC. Conclusions: Owing to the…
Wild-type JAK2 secondary acute erythroleukemia developing after JAK2-V617F-mutated primary myelofibrosis.
2009
A 54-year-old female patient developed acute erythroleukemia after an 8-year course of primary myelofibrosis. The latter harbors the JAK2-V617F mutation and was treated with hydroxyurea and anagrelide. A bone marrow trephine biopsy disclosed 2 morphologically distinct areas of chronic primary myelofibrosis and acute erythroleukemia. Microdissection and a separate molecular pathological analysis was performed. Although the activating JAK2-V617F mutation was not maintained in blasts of acute erythroleukemia, it was detectable in the chronic phase of primary myelofibrosis, indicating that this mutation did not play a role in the leukemic transformation of erythroid cells.
Therapy with lamivudine and steroids in a patient with acute hepatitis B and rapidly progressive glomerulonephritis.
2006
To the Editor: Tang et al.1 recently reported that lamivudine (LAM) improves renal outcome in patients with chronic hepatitis B virus (HBV) infection and membranous nephropathy. We would like to add our experience on acute hepatitis B and rapidly progressive glomerulonephritis.
Instruction of haematopoietic lineage choices, evolution of transcriptional landscapes and cancer stem cell hierarchies derived from an AML1-ETO mous…
2013
The t(8;21) chromosomal translocation activates aberrant expression of the AML1-ETO (AE) fusion protein and is commonly associated with core binding factor acute myeloid leukaemia (CBF AML). Combining a conditional mouse model that closely resembles the slow evolution and the mosaic AE expression pattern of human t(8;21) CBF AML with global transcriptome sequencing, we find that disease progression was characterized by two principal pathogenic mechanisms. Initially, AE expression modified the lineage potential of haematopoietic stem cells (HSCs), resulting in the selective expansion of the myeloid compartment at the expense of normal erythro- and lymphopoiesis. This lineage skewing was foll…
Post-traumatic Stress Disorder and Risk Factors in Patients With Acute Myocardial Infarction After Emergency Percutaneous Coronary Intervention: A Lo…
2021
This study aimed to investigate the status and risk factors of post-traumatic stress disorder (PTSD) in patients with acute myocardial infarction (AMI) after emergency percutaneous coronary intervention (PCI) in acute and convalescence phases. A longitudinal study design was used. Two questionnaire surveys were conducted in the acute stage of hospitalization, and 3 months after onset in patients. Logistic regression was used to analyze the risk factors for PTSD in AMI patients. The incidence of PTSD was 33.1 and 20.4% in acute and convalescent patients, respectively. The risk factors related to PTSD were door-to-balloon time (DTB) (≥92.6 min), left ventricular ejection fraction (LVEF) (&…
