[Far East scarlet-like fever in a Caucasian man with Yersinia pseudotuberculosis bacteriaemia].

Yersinia pseudotuberculosis is a Gram-negative bacterium causing infection in humans through contaminated water and/or food. The infection commonly occurs as gastroenteritis and fever, abdominal pain due to mesenteric lymphadenitis and diarrhoea. Bacteraemia is rare and is typically seen in immunocompromised patients and occurs with different clinical presentations like Far East scarlet-like fever, splenic abscess, or mimic appendicitis. This is a case report of Y. pseudotuberculosis bacteraemia and splenic abscess in a Caucasian male.

Effects of a 12-week aerobic exercise on markers of hypertension in men.

Introduction: This study was aimed at determining the effects of a 12-week aerobic exercise program on markers of hypertension in men. Methods: The study was of a semi-experimental design featuring repeated measurements. A total of 40 men (age range=37.9 ± 2.68) with primary hypertension were divided into two groups, namely, the exercise group (n=20) and the control group (n=20) (systolic blood pressure [SBP]: 140.531 ± 0.23, diastolic blood pressure [DBP]: 90.71 ± 0.05). The exercise group participated in a 12-week aerobic exercise program (55% to 70% of HRmax). Blood samples were taken from both groups at the baseline and at the 4th, 8th, and 12th weeks of the training program for the assessment of adiponectin, paraoxonase-1 (PON-1), and hydrogen peroxide (H2 O2 ) levels as the markers for investigation. A linear mixed model was also used to evaluate the association among the markers. Results: In the exercise group, exercise reduced the SBP and DBP at week 12 (P=0.031 and 0.023, respectively), and adiponectin increased at weeks 8 and 12 (P=0.014 and 0.001, respectively). The plasma PON-1 level showed a significant increase in all the three stages of measurement (P=0.007, 0.004, and 0.002 at weeks 4, 8, and 12, respectively), whereas the H2 O2 levels showed a significant decrease at weeks 8 and 12 (P=0.013 and 0.011, respectively). The control group exhibited significantly decreased PON-1 (P=0.003) and adiponectin (P=0.025) levels but significantly increased SBP at week 12 (P=0.032). Conclusion: The exercise-induced reduction of oxidative stress exerts a considerable effect on the reduction of blood pressure in hypertensive patients. According to our results increase in oxidative stress has the great impact on the of blood pressure.

Physical activity and beta-amyloid pathology in Alzheimer's disease: A sound mind in a sound body.

Alzheimer's disease (AD) is the most common type of dementia worldwide. Since curative treatment has not been established for AD yet and due to heavy financial and psychological costs of patients' care, special attention has been paid to preventive interventions such as physical activity. Evidence shows that physical activity has protective effects on cognitive function and memory in AD patients. Several pathologic factors are involved in AD-associated cognitive impairment some of which are preventable by physical activity. Also, various experimental and clinical studies are in progress to prove exercise role in the beta-amyloid (Aß) pathology as a most prevailing hypothesis explaining AD pathogenesis. This study aims to review the role of physical activity in Aß-related pathophysiology in AD.
