Objective: The study aims to compare the effectiveness of individual and group nutrition education methods in improving key anthropometric and biochemical markers in drug-treated, overweight-obese hypertensive adults.

Methods: The randomized trial included 170 patients with pharmacologically well-controlled primary hypertension and body mass index (BMI) ≥ 25 kg/m. For six months, the patients received six sessions, either one-to-one individual nutrition education (IE, = 89) or group education (GE, = 81), developed by dietitians.

Background/aims: Benefits resulting from weight loss and dietary approaches to stop hypertension (DASH) diet in the treatment of arterial hypertension led to a search for a better therapy that would include psychological factors. The present study aimed to assess the relationship between the personality traits included in the Big Five personality traits and the effectiveness of treatment for weight loss in patients with essential hypertension and excessive body weight.

Methods: The study involved 84 patients with essential hypertension, overweight or obesity, managed by a hypertensiologist.

Background And Aim: The aim of the study was to assess the impact of individualised nutritional intervention based on the DASH diet (Dietary Approaches to Stop Hypertension) on the nutritional status, blood pressure, and selected biochemical parameters of obese/overweight patients with primary arterial hypertension.

Methods: A total of 131 participants were randomised to the DASH intervention group (DIG; n = 69, 33 males) or the control group (CG; n = 62, 32 males). A three-month nutritional intervention was carried out in the DIG group, while the control group received only standard recommendations.

Background: Iron deficiency may impair aerobic performance. This study aimed to determine whether treatment with intravenous iron (ferric carboxymaltose) would improve symptoms in patients who had heart failure, reduced left ventricular ejection fraction, and iron deficiency, either with or without anemia.

Methods: We enrolled 459 patients with chronic heart failure of New York Heart Association (NYHA) functional class II or III, a left ventricular ejection fraction of 40% or less (for patients with NYHA class II) or 45% or less (for NYHA class III), iron deficiency (ferritin level <100 microg per liter or between 100 and 299 microg per liter, if the transferrin saturation was <20%), and a hemoglobin level of 95 to 135 g per liter.
