Present trends in bariatric surgery in Poland.

Introduction: As obesity has become a major health problem in Poland and bariatric procedures are the best way of treatment, an increasing trend has been observed in Polish bariatric surgery for the last decade.

Aim: Our purpose was to provide an updated overview of the bariatric surgical procedures performed in Polish institutions in comparison to the situation in Europe as well as to analyze the trends in Polish bariatric surgery over the last decades.

Material And Methods: A questionnaire about the number and type of bariatric procedures performed in 2016 was sent to all Polish surgical departments.

[Implication of probability analysis for diagnosis of stable coronary diseases. Comparison of non-invasive diagnostic tests].

Unlabelled: A prospective collection of clinical (history), electrocardiography (ECG), exercise electrocardiography (EE), dobutamine stress echocardiography (SE) and catheterization data was performed in 551 patients with chest pain regarded as definite or probable stable angina pectoris. All patients (65% male) without prior history of myocardial infarction undergone clinical evaluation: chest pain classification according to Diamond, ECG, EE (regarded as positive on the basis of > or = 1 mm ST-depression), SE (ischemia was defined as new or worsening wall motion abnormalities using a 16-segment model) and coronary angiography (CA):CAD was defined as > or = 50% narrowing of at least one major vessel. Sensitivity and specificity of ECG, EE, SE was calculated: and results are as follows respectively: 23% and 87%, 93% and 21%, 85% and 69%.

Prediction of lethal or life-threatening cardio-circulatory events in patients who apparently are not at risk : a preliminary retrospective echocardiographic study.

Major cardio-circulatory events, defined as circulatory death, myocardial infarction, unstable angina, or stroke, sometimes occur unexpectedly in patients who apparently have no evident increase in risk (absence of overt heart failure, hypertrophy, uncontrolled or severe hypertension, previous or present myocardial infarction, angina, myocarditis, infectious or any other pericardial, valvular or great vessel disease, heart malformation, significant arrhythmia or conduction disturbances). To investigate whether 2D-guided M-mode echocardiographic variables have predictive value in such patients, a retrospective analysis of 1,965 cases was performed. Twenty-one patients were found who on the day of echocardiographic examination fulfilled the above criteria, but suffered major cardio-circulatory events during the first following year (1 yr group), 12 during the second year (2 yr group), and 16 during the third year (3 yr group).
