To examine the impact of TRE on HR-QoL in adults.

Two researchers were involved in the screening and paper selection process. A single researcher extracted all relevant data from eligible studies.

Overall, 10 studies were eligible for inclusion in this systematic review. Four studies reported improvements in overall HR-QoL scores among participants with type 2 diabetes, middle-aged women with obesity, generally healthy adults, and generally healthy adult employees. Three studies reported significant and nonsignificant improvements in some domains of HR-QoL assessment tools among overweight, sedentary older adults, overweight or obese adults, and 24-hour shift workers. No studies reported that TRE adversely affected HR-QoL. Improvements in HR-QoL appeared to occur primarily at 12 weeks/3 months. There was no clear relationship between HR-QoL scores and TRE protocol, additional study outcomes, participant health status, age, or adherence. Although further research is required to elucidate the impact of TRE on HR-QoL, the findings reveal that no studies show that TRE adversely affects HR-QoL.

This systematic review aimed to critically investigate the effect of the MedDiet on glycation markers in healthy or overweight individuals with type 2 diabetes or cardiovascular disease.

The authors of most of the studies demonstrated a reduction in serum concentrations of advanced glycation end products (AGEs), such as εN-carboxymethyllysine and methylglyoxal, and in skin autofluorescence levels after at least 4 weeks of adherence to the MedDiet. The MedDiet also led to positive effects on gene expression of receptors for AGEs, as RAGE and AGER1, and an enzyme involved in detoxification (glyoxalase I). There is no evidence that short-term adherence affects glycation markers.

Glycation markers improved in response to the MedDiet. The possible mechanisms involved may be related to the low AGE and refined sugars content of the diet, as well as its high monounsaturated fatty acid, phenolic compound, and dietary fiber contents.

This review aims to summarize recent studies that highlight the complex relationship between nutrition, carbohydrate, insulin provision and glycaemic control in the critically ill patient population.

Results of observational studies concur to support early hypoglycaemia and persisting hyperglycaemia as life-threatening events. In contrast, interventional studies indicate that early macronutrient restriction appears to reduce the benefits related to insulin therapy. This restriction is however associated with improved outcomes in itself. The potential role of modified enteral solutions as an adjunctive treatment to attenuate hyperglycaemia warrants further research. The selection of a therapeutic modality may also differ according to the characteristics of the setting, such as the nurse-to-patient ratio, the type and accuracy of meters, including near-continuous glucose monitoring and the availability of computer-guided protocols.

There appears to be significant interplay between nutrition, including carbohydrate provision, blood glucose control and clinical outcomes. Individualized care is probably needed to define the optimal glucose target and nutritional intervention. This can differ according to the preexistence of chronic hyperglycaemia, the timing from the onset of critical illness and the clinical condition itself.
