RESUMO
Considering the progressive nature of type 2 diabetes, glycated hemoglobin (HbA1c) goals and treatment plans should be regularly tailored to the patient's need to prevent hypoglycemia. There are individual HbA1c target levels that take into account factors such as age, comorbidity, and risks of treatment. The emergence of new therapeutic classes reducing hypoglycemia has changed ongoing practices. This article presents a potentially preventable case of a patient with hypoglycemia and reflects on the latest European and American recommendations for antidiabetic treatment in elderly patients.
Le diabète de type 2 étant une maladie progressive, les objectifs d'hémoglobine glyquée (HbA1c) et le traitement doivent être régulièrement adaptés aux besoins du patient pour prévenir les hypoglycémies. À cet effet, il existe des valeurs cibles d'HbA1c individuelles qui tiennent compte de l'âge, des comorbidités du patient et des risques liés aux traitements. L'arrivée de nouvelles classes thérapeutiques limitant les hypoglycémies a modifié les pratiques récentes. Cet article illustre un cas d'hypoglycémie potentiellement évitable et reprend les dernières recommandations européennes et américaines sur le traitement antidiabétique chez le patient âgé.

BACKGROUND: An adjunctive topical therapy with gentamicin-sponges to systemic antibiotic therapy might improve the healing of infected diabetic foot ulcers (DFUI). METHODS: Single-center, investigator-blinded pilot study, randomizing (1:1) the gentamicin-sponge with systemic antibiotic versus systemic antibiotics alone for patients with DFUI. RESULTS: We included 88 DFUI episodes with 43 patients in the gentamicin-sponge arm and 45 in the control arm. Overall, 64 (64/88; 73%) witnessed total clinical cure, 13 (15%) significant improvement, and 46 (52%) showed total eradication of all pathogens at the final visit. Regarding final clinical cure, there was no difference in favour of the gentamicin-sponges (26/45 vs. 31/43; p = 0.16). However, the gentamicin-sponge arm tended to a more rapid healing. In multivariate analysis adjusting for the case-mix, the variable "gentamicin-sponge" was not significantly associated with "cure and improvement". Gentamicin-sponges were very well tolerated, without any attributed adverse events. CONCLUSIONS: The gentamicin-sponge was very well tolerated, but did not significantly influence overall cure. TRIAL REGISTRATION: ClinicalTrials.gov ( NCT01951768 ). Date 2 April 2013.

Diabetic foot complications are a public health challenge and preventive measures although simple are often not enforced, as evidenced by the lack of decrease in the rate of ulcers and amputation in Switzerland. This article proposes a risk score to grade individual risk of the diabetic patient and an individualized prevention measures as this risk. We discuss the importance of collaboration of various specialists. Two areas are important, first the early involvement of specialists in revascularization because the diabetic population with feet at risk of ulcération risk nowadays primarily has neuro-ichemic ulcerations and also the close collaboration with podiatrists and orthopedic shoemakers who are full partners of the multidisciplinary team.

News on the front of diabetes have revealed the remarkable results of multifactorial treatment of type 2 diabetes on morbidity and mortality. Micro and macro-angiopathic complications have markedly decreased during the last 20 years. However, intervention trials on glycemic control alone show a slight or no benefit on cardiovascular complications or mortality when intensive treatment aims at HbA1c below 7.0-7.5%. Life adaption remains a critical part of diabetes treatment to decrease cardiovascular risk. Recent knowledge on nutrition and meal frequency has taught us to distrust old dogmas.

Foot infections are a frequent and potentially harmful complication of diabetes mellitus. In one skin ulceration out of two, further evolution towards infection occurs and often leads to amputation increasing morbidity and health care costs. Skin disruptions, favored by the sensorimotor neuropathy and vascular disease, constitute the initial factors leading to this complication. To ensure effective care, these cases must be managed by a multidisciplinary team in a specialized center. All caretakers involved with patients suffering from diabetes mellitus must be capable of preventing and recognizing diabetic foot infections, as well as informing the patients about this complication and its management.

Transsphenoidal surgery is the treatment of choice for acromegaly due to pituitary adenoma but it is not always possible to reduce or control tumor growth, inhibit GH hypersecretion and normalize IGF-I. The first-line drug treatment in 2013 remains the somatostatin analogues. In 2012 and 2013 have been published several publications presenting the prognosis of well-differentiated thyroid cancers of intermediate risk. Indeed, the dose of radioactive iodine administered to patients with "favorable" histology in this risk category should be reduced without change in prognosis. Elastograhy could, in combination with conventional ultrasound features, allow a better selection of thyroid nodules that need a cytology, with, however, still limitations in the detection of follicular carcinomas.

Diabetes is a major risk factor for cardiovascular diseases. Although aspirin is considered a cornerstone of the prevention and treatment of atherothrombotic-related ischemic events, this antiplatelet drug appears to be less effective in patients with poorly controlled diabetes. It has been suggested that the glycation of platelet proteins plays a pivotal role in poor responsiveness to aspirin. However, a direct effect on the critical residue (serine 529, or Ser 529) of the catalytic pocket of cyclooxygenase 1 (COX-1) has never been demonstrated. This pilot study aimed to elucidate the impact of hyperglycaemia on aspirin acetylation of COX-1 using a targeted mass spectrometry approach. We observed that high glucose concentration had a direct impact on the level of acetylation of the COX-1 Ser 529 residue, whereas it's overall acetylation level remained unchanged. Moreover, the functional aspirin-induced inhibition of COX-1 was dose-dependently impaired as glucose concentrations increased. These in vitro findings were in line with data obtained using platelets from diabetic patients. These data provide new insights into the interplay between glucose and aspirin on platelet proteins and their effects on platelet COX-1. They also suggest a potential mechanistic explanation for the phenomenon of poor response to aspirin in diabetic patients. Data are available via ProteomeXchange with identifier PXD011204. SIGNIFICANCE: Deciphering the mutual interplay between glucose and aspirin-mediated acetylation on platelet COX-1, might be of great interest as there is still a lack of information of the mechanism underlying this process that may contribute to the less-than expected response of platelets to aspirin, often observed in diabetes.

This data article associated with the manuscript "A high glucose levels is associated with decreased aspirin-mediated acetylation of platelet cyclooxygenase (COX)-1 at serine 529: a pilot study" (Finamore et al., 2018) refers to the shotgun proteomics approach carried out on platelet protein extracts from diabetic patients and healthy controls. Platelet proteins were in vitro incubated with 500⯵M aspirin for 30â¯min at 37⯰C to enhance the acetylation process. After protein digestion with trypsin, DDA data were acquired on a Thermo QExactive plus using 3 technical replicate injections per sample. Here, we were able to elucidate the preferential sites of aspirin-induced acetylation on a significant fraction of the platelet proteome and to quantify the impact of diabetes on the effect of aspirin on several platelet proteins. Data are available via ProteomeXchange with identifier PXD011582.
RESUMO
BACKGROUND: Clinical experience suggests that a high proportion of orthopaedic infections occur in persons with diabetes. METHODS: We reviewed several databases of adult patients hospitalized for orthopaedic infections at Geneva University Hospitals from 2004 to 2014 and retrieved 2740 episodes of infection. RESULTS: Overall, diabetes was noted in the medical record for 659 (24%) of these cases. The patients with, compared with those without, diabetes had more than five times more foot infections (274/659 [42%] vs 155/2081 [7%]; p < 0.01) and a significantly higher serum C-reactive protein level at admission (median 96 vs 70 mg/L; p < 0.01). Diabetic patients were older (median 67 vs 52 years; p < 0.01), more often male (471 [71%] vs 1398 [67%]; p = 0.04), and had more frequent polymicrobial infections (219 [37%] vs 353 [19%]; p < 0.01), including more gram-negative non-fermenting rods (90 [15%] vs 168 [9%]; p < 0.01). Excluding foot infections from these analyses did not change the statistically significant differences. Diabetes was present in 17% of all infected orthopaedic patients without foot involvement. In Geneva canton, the overall prevalence of diabetes is estimated at 5.1%, while we have found that the prevalence is 13% in our hospitalized adults. CONCLUSIONS: Diabetes is present in 24% of all adult patients hospitalized for surgery for an orthopaedic infection, a prevalence that is several times higher than for the general population and twice as high as that for the population of hospitalized patients. Compared with non-diabetics, patients with diabetes have significantly more infections that are polymicrobial, including gram-negative non-fermenting rods.
