Background: Obesity and exercise are associated with disturbances of mineral metabolism, which can lead to physical inefficiency. Our study aimed to compare the influence of endurance and endurance–strength training on mineral status in women with abdominal obesity. Methods: Thirty-eight abdominally obese women were randomized into groups A and B and underwent 3 months long training: group A—endurance training and group B—endurance–strength training. Anthropometric and body composition measurements were carried out and the Graded Exercise Test was performed. Blood, urine, and hair samples were collected for mineral content analysis. Results: Endurance training decreased serum Fe and Zn concentrations as well as hair Zn and Cu content, and increased urine Zn concentration. Endurance–strength training increased serum Mg and Cu concentrations, decreased serum Fe and Zn concentrations, decreased hair Ca and Mg content, and increased urine Ca and Zn concentrations. After training, serum and urine Fe concentration was higher in group A, while urine Ca concentration was higher in group B. A number of correlations was found. Conclusions: Both endurance and endurance–strength training have a significant effect on mineral metabolism in obese women; the favorable effects of endurance–strength exercise predominate in iron, magnesium, zinc, and copper balance.

Rationale Acute calculous cholecystitis is a prevalent disease whose diagnosis and management still face significant debate. Although the overall incidence of gallstone disease is 18.8% in European women aged 30 to 69 years, there is little data and experience in managing acute calculous cholecystitis in populations over 80 years old. The incidence of acute cholecystitis among the elderly is probably increasing. For the reason, we here highlight the advantages and disadvantage of various treatment and management opens based on a 96-year-old patient. Patient concerns We present a rare case in which a 96-year-old woman suffered from abdominal pain, nausea, and lack of appetite for over a month. Diagnoses She was diagnosed with acute calculous cholecystitis and pancreatitis. Interventions She was successfully treated without surgery, regaining her physical health after 5 months. Outcomes The question of how to manage acute calculous cholecystitis is extremely difficult in many aspects. The patient of very advanced age presented in this paper, not very well diagnosed and with a life-threating condition, survived because of careful treatment and reasonable decision-making. Lessons The take-away from this case is that, in a high-risk senile patient, strict conservative therapy of cholecystitis may be successful, as it can avoid the complications of surgery and leave the patient with a good quality of life.
