The Latin American Society of Pediatric Infectious Diseases (SLIPE by its Spanish acronyms) is working to understand the current situation, gaps, and opportunities for traceability of the quality vaccination process in Latin America and the Caribbean.On September 24th and 25th, a Latin American forum of experts in immunization programs was held through the Zoom platform; the topics discussed included: computerized systems for recording immunizations, vaccination programs traceability, challenges, and information systems for the integrated management of vaccination.Latin American countries have transitioned from having a nominal registration system to a nominal tracking system, with many of them not migrating their platforms to new technologies; therefore, the low-quality data, fragmented databases, and slow information traffic present a challenge that must be taken on.

Background: The glucosuria induced by sodium-glucose cotransporter-2 inhibitors (SGLT2i) stimulates endogenous (hepatic) glucose production (EGP) blunting the decline in HbA1c. We hypothesized that, in response to glucosuria, a renal signal is generated and stimulated EGP. Aim: To examine the effect of acute administration of dapagliflozin (DAPA) in nondiabetic, renal transplant subjects on SGLT2i-induced stimulation of EGP. Methods: 20 subjects [10 with intact native kidneys (IK) and 10 with bilateral nephrectomy (NK)] underwent measurement of EGP ([6,6-2H2]-glucose) before and for 6 hours after administration of DAPA or placebo (PLC) on 2 separate days. Results: DAPA induced greater glucosuria in subjects with IK versus NK (8.6±1.1 vs. 5.5±0.5 grams/6-hrs; p=0.02). During 6-hour, plasma glucose decreased slightly and similarly in both groups, with no difference compared to PLC. Following PLC, there was a progressive time-related decline in EGP that was similar in both groups. Following DAPA, EGP declined in both groups but the decrement in EGP was 56% greater in the NK. During DAPA, urinary glucose excretion was correlated with EGP (r = 0.34, p Conclusions: In NK subjects the hepatic compensatory response to acute SGLT2i-induced glucosuria was attenuated compared to diabetic subjects with IK, suggesting a SGLT2i-mediated stimulation of hepatic glucose production via efferent renal nerves in an attempt to compensate for the urinary glucose loss, i.e., a renal-hepatic axis.

The stochasticity of fluid and sediment parameters has been identified as a source of diffusion, particularly anomalous diffusion at different temporal and spatial scales of bed load particle trajectories. Data from two sets of flume experiments are presented, one data set has gravel particle trajectories tracked over a limited area and was used in identifying the influence of different shear stress conditions on diffusive processes. A new experiment was performed using spherical particles moving as bed load in an annular flume in order to address concerns about censorship effects caused by the size of the detection window. An annular flume allowed collection of practically uncensored particle trajectories over longer time period than has been previously possible in the laboratory. Three diffusive regimes were observed at distinct stages of particle motion: (i) ballistic regime at the local range; (ii) Fickian diffusion at the intermediate range; (iii) subdiffusion at the global range. Characteristic time scales separate the regimes and correlate with the mean traveling and resting times of particles. Fickian diffusion in the intermediate range is first recognized as a result of the balance between intermittent weak transport and near-bed turbulence, as first predicted by Nikora et al. (2002, https://doi.org/10.1029/2001WR000513). In the global range, extreme values were observed in the distribution of particle resting times, suggesting that two types of distributions (related to surface motion and vertical mixing) were responsible for the subdiffusion at longer time scales. Diffusion was found to be anisotropic at all stages of particle motion.

Aims/hypothesis The glucosuria induced by sodium–glucose cotransporter 2 (SGLT2) inhibition stimulates endogenous (hepatic) glucose production (EGP), blunting the decline in HbA1c. We hypothesised that, in response to glucosuria, a renal signal is generated and stimulates EGP. To examine the effect of acute administration of SGLT2 inhibitors on EGP, we studied non-diabetic individuals who had undergone renal transplant with and without removal of native kidneys. Methods This was a parallel, randomised, double-blind, placebo-controlled, single-centre study, designed to evaluate the effect of a single dose of dapagliflozin or placebo on EGP determined by stable-tracer technique. We recruited non-diabetic individuals who were 30–65 years old, with a BMI of 25–35 kg/m2 and stable body weight (±2 kg) over the preceding 3 months, and HbA1c Results Twenty non-diabetic renal transplant patients (ten with residual native kidneys, ten with bilateral nephrectomy) participated in the study. Dapagliflozin induced greater glucosuria in individuals with residual native kidneys vs nephrectomised individuals (8.6 ± 1.1 vs 5.5 ± 0.5 g/6 h; p = 0.02; data not shown). During the 6 h study period, plasma glucose decreased only slightly and similarly in both groups, with no difference compared with placebo (data not shown). Following administration of placebo, there was a progressive time-related decline in EGP that was similar in both nephrectomised individuals and individuals with residual native kidneys. Following dapagliflozin administration, EGP declined in both groups, but the differences between the decrement in EGP with dapagliflozin and placebo in the group with bilateral nephrectomy (Δ = 1.11 ± 0.72 μmol min−1 kg−1) was significantly lower (p = 0.03) than in the residual native kidney group (Δ = 2.56 ± 0.33 μmol min−1 kg−1). In the population treated with dapagliflozin, urinary glucose excretion was correlated with EGP (r = 0.34, p Conclusions/interpretation In nephrectomised individuals, the hepatic compensatory response to acute SGLT2 inhibitor-induced glucosuria was attenuated, as compared with individuals with residual native kidneys, suggesting that SGLT2 inhibitor-mediated stimulation of hepatic glucose production via efferent renal nerves occurs in an attempt to compensate for the urinary glucose loss (i.e. a renal–hepatic axis).

The results report a significant increase in social self-esteem, academic / work self-esteem; Home self-esteem and general self-esteem in students considering the measures used before and after the training received.

Cerebrovascular accidents (CVA) represent a major complication in diabetes (DM). Real-life evidence as to whether modern management of CVA and DM have softened this relationship is currently limited. We assessed the prevalence of DM, previously known or newly-diagnosed, in all patients (N=542, males 51.5%) admitted for CVA at the Stroke Unit (SU) of Verona University Hospital from 1/1/2015 to 12/31/2016. DM was ascertained by previous diagnosis, glucose-lowering therapy at admission/discharge or admittance plasma glucose (PG) ≥11.1 mmol/L. Prevalence of DM was 21.03% (78.1% known-DM; 21.9% new-DM). In-hospital death rate was 10.5%. Compared to non-DM, patients with DM showed an increased risk of death (15.8 vs. 9.1%; OR 1.87 95% CI, 1.03-3.41) and complications (48.2 vs. 33.3%; 1.87, 1.22-2.86) with similar duration of hospitalization (mean±SEM, 9.14±1.06 vs. 8.80±0.39 days, p=0.72). All deaths occurred in the SU. The “survivors” with DM transferred to non-intensive ward had an out-of-SU hospital stay twice as longer than non-DM (2.32±1.02 vs. 0.98±0.19 days, p=0.038). After multivariable adjustment, DM remained predictor of complications (adj-OR 1.87, 1.22-2.86) but not mortality (1.79, 0.92-3.46). Patients in the highest PG quartile (≥6.55 mmol/L) displayed the highest risk of death (7.89, 2.73-22.79; PG In conclusion, these data highlight that DM frequently occurs in patients admitted for CVA and adds an excess burden of adverse clinical outcomes that urgently calls for strategies to anticipate DM diagnosis in high-risk individuals.
