RESUMEN
Diabetic foot ulcers (DFUs) remain a major cause of morbidity. This narrative mini-review aimed to investigate the potential role of folic acid (FA) in DFUs. Individuals with DFUs exhibit lower levels of FA and lower daily intake, compared to those without DFUs. There is preliminary evidence that FA administration may contribute to improved DFUs healing. In this context, regular evaluation of dietary FA intake may prove important towards reduction or even prevention of DFUs. However, data are still limited and further research is required to enable definitive conclusions and any recommendations.
RESUMEN
This narrative review aimed to discuss the potential interplay among frailty syndrome, sarcopenia and metformin in type 2 diabetes mellitus (T2DM). There is emerging evidence on the potential protective role of metformin on both frailty and sarcopenia. However, results are not always consistent. Thus, further research is needed to provide a definitive answer on any role of metformin in improving frailty and/or sarcopenia in T2DM.

The aim of this nonsystematic mini review was to discuss serum levels of zinc in subjects with diabetic foot ulcers (DFUs). Most studies have reported low zinc levels in subjects with DFUs. Furthermore, there is some evidence that oral zinc supplementation may have a positive and beneficial impact on DFUs healing. Nonetheless, findings have so far not provided definitive answers. More studies are needed to clarify the role of zinc and its supplementation in this setting.
RESUMEN
This narrative mini-review discusses vitamin E levels in subjects with diabetic foot ulcers (DFUs). Vitamin E may be reduced in subjects with DFUs, but this finding is inconsistent. Its administration appears to benefit patients with DM, delaying the onset of complications, including DFU. There is also evidence that it may promote DFU healing. Nonetheless, further studies are required to confirm these promising results and estimate vitamin E administration's cost-effectiveness.
RESUMEN
There is accumulating evidence that magnesium, an important mineral having a pivotal role in many physiological functions, may be important in development and healing of diabetic foot ulcers (DFUs). In this non-systematic mini review, we discuss the role of magnesium in DFUs, as well as the effects of magnesium administration in DFUs. Reduced Mg levels appear to be associated with DFUs. Moreover, Mg administration may be beneficial for the outcome of DFUs. Further investigation is imperative in order to shed more light on these findings.
RESUMEN
The aim of this narrative non-systematic review was to investigate the potential interplay among frailty syndrome, sarcopenia and diabetic kidney disease (DKD) in type 2 diabetes mellitus (T2DM) patients. Data derived from a limited number of studies underline that DKD is a significant risk factor for frailty. On the other hand, frailty syndrome poses a higher risk for end-stage renal disease (ESRD) in subjects with DKD. In addition, frailty seems to affect the cognitive function and social life of DKD individuals, whilst as DKD deteriorates, there is a higher prevalence of sarcopenia which is a fundamental frailty factor. As a result, it is shown that a bidirectional relation is established between these entities, as diabetes mellitus (DM) affects the components of frailty and sarcopenia and vice versa. This vicious cycle is created through multiple pathophysiologic mechanisms, including the anabolic role of insulin, low-grade inflammation, cytokines and endothelial function, prompting further investigation in this area. Specific nutritional and exercise interventions are imperative to be established in order to ameliorate potential adverse outcomes, concerning these entities.

This narrative mini-review article aimed to investigate the potential association of vitamin B12 levels with diabetic neuropathy (DN) and diabetic foot ulcers (DFUs). It was demonstrated that B12 deficiency seems to be related to DFUs in cases of metformin administration and bariatric surgery. B12 supplementation with dietary measures and agents may improve DN and quality of life (QoL). However, data are still preliminary and more experience is needed.
RESUMEN
The aim of this narrative mini review was to investigate the potential association of the diabetic foot (DF) with sarcopenia and frailty. Data is still limited, but it appears that DF patients may be more prone to frailty. In addition, patients with DF and sarcopenia exhibit more frequently foot ulcers and amputations, as well as increased mortality rates post-operatively. Further studies are now needed to see how these realizations may be used in clinical practice, aiming to improve DF outcomes.
RESUMEN
Dulaglutide is an injectable glucagon-like peptide-1 receptor agonist approved for the treatment of adults with type 2 diabetes. Angioedema is defined as self-limiting edema, localized in the deeper layers of the skin and mucosa. Angioedema can be hereditary or acquired which can be allergic due to reactions to foods, insect bites and stings, and latex, drug-induced, caused by physical stimuli and associated with lupus erythematosus and hypereosinophilia. Angioedema represents a rare adverse event of glucagon-like peptide-1 receptor agonists. The only glucagon-like peptide-1 receptor agonist that has been mentioned to induce angioedema in literature is exenatide. We report the first case of dulaglutide-associated angioedema in a 72-year-old male in order to point out to the clinicians this potential rare side effect of this drug and its clinical significance.
RESUMEN
AIM: The chemokine fractalikine is expressed in vascular endothelium, exerting a pro-atherogenic effect. Two single-nucleotide polymorphisms of the CX3CR1 gene (T280M and V249I) affect frac-talkine receptor expression and function. We aimed to assess the prevalence of CX3CR1 polymor-phisms and the association with ischemic cerebrovascular attacks in a cohort of carotid atheromatous disease patients and age-matched controls. METHODS: Using PCR-RFLP, we analyzed allelotypes for T280M and V249I in 150 patients with and 151 controls without carotid atherosclerosis assessed using carotid duplex ultrasound; the subjects were patients admitted for any reason to a tertiary hospital. Genotype data were compared with modifiable risk factors for cerebrovascular disease and the reason for admission, using ischemic stroke as an endpoint. Stroke types associated with carotid atherosclerosis were analysed separately. RESULTS: The M280 allelic frequency was lower among carotid atherosclerosis patients than controls (0.15 versus 0.23, adjusted OR 0.47, 95% CI 0.30-0.74). Absence of M280 allele was an indepen-dent factor associated with carotid atherosclerosis (OR 3.70, 95% CI 1.92-7.14), stronger than hypertension, dyslipidemia, diabetes and cigarette smoking. The I249 allele was also under-repre-sented in carotid atherosclerosis; this was not statistically significant. T280M and V249I genotypes were not associated with admission due to ischemic stroke of the large vessel subtype (TOAST classi-fication, 73 episodes), whereas carotid atherosclerosis, previous ischemic event, age, hypertension, diabetes, hyperlipidemia and cigarette smoking were all independently associated. CONCLUSIONS: The M280 fractalkine receptor gene allele is associated with a lower risk of carotid ath-eromatous disease, independent from the modifiable cerebrovascular risk factors.
