[Metabolic Stone assessment: Underused tool and how to implement it on daily practice.]

Nephrolithiasis is a highly prevalent disease presenting itself mostly at a working age, which leads to a great economic burden on health system. Kidney Stone disease should be viewed as a systemic disorder,associated with or predictive of hypertension, insulin resistance, chronic kidney disease and cardiovasculardamage. According to current guidelines and evidence,a full screening of risk factors for kidney stones and for cardiovascular damage should be recommended in all cases of kidney stone disease, yet it is rarely performed, and a real-world clinical practice is lacking. The aim of this narrative literature is to serve as guidance for a patient-tailored dietary suggestion after a clinical and biochemistry evaluation, with limited resources, and still offer a rational management of kidney stone patients. Meta-analysis, systematic review, experimental studies, case-control plus high-impact factor journals PubMed and EMBASE, on the topic were included. Search criteria included metabolic profile, metabolic work-up, kidney stone, urolithiasis between 2010 and 2020.

Cardiac rehabilitation in older patients: Indication or limitation?

OBJECTIVE

To assess the clinical impact of a cardiac rehabilitation program in an older population.

METHODS

This is a retrospective analysis of 731 coronary patients who attended phase 2 of a cardiac rehabilitation program between January 2009 and December 2016. We compared the response to the program of older (≥65 years) and younger (<65 years) patients, analyzing changes in metabolic profile (including body mass index, waist circumference and lipid profile), exercise capacity, cardiac autonomic regulation parameters (such as chronotropic index and resting heart rate), and health-related quality of life scores.

RESULTS

Older patients represented 15.9% of our cohort. They showed significant reductions in waist circumference (male patients: 98.0±7.9 cm vs. 95.9±7.9 cm, p<0.001; female patients: 90.5±11.4 cm vs. 87.2±11.7 cm, p<0.001), LDL cholesterol (102.5 [86.3-128.0] mg/dl vs. 65.0 [55.0-86.0] mg/dl, p<0.001) and triglycerides (115.0 [87.8-148.5] mg/dl vs. 97.0 [81.8-130.0] mg/dl, p<0.001). Post-training data also showed a noticeable improvement in older patients' exercise capacity (7.6±1.8 METs vs. 9.3±1.8 METs, p<0.001), along with a higher chronotropic index and lower resting heart rate. Additionally, health-related quality of life indices improved in older subjects. However, our overall analysis found no significant differences between the groups in changes of the studied parameters.

CONCLUSION

Older coronary patients benefit from cardiac rehabilitation interventions, similarly to their younger counterparts. Greater involvement of elderly patients in cardiac rehabilitation is needed to fully realize the therapeutic and secondary preventive potential of such programs.
