Diazepam's amnestic effects mirror those in patients with probable severe medial temporal damage, mostly restricted to initial consolidation and differ from other OAA (Korsakoff syndrome, frontal, transient epileptic, posttraumatic amnesia, and most progressive amnesias) in terms of WMC, susceptibility to RI and accelerated forgetting.

To assess the association between taking antibiotics in pregnancy and the occurrence of infections in children at four years of age.

We studied children who participated in the follow-up of the birth cohort Generation XXI, Porto-Portugal, at the age of four years. We evaluated the associations between the use of antibiotics by the mother at any time in pregnancy with the occurrence of infections. Data were analysed using logistic regression, controlling for potential confounding variables.

We studied 7459 children (50.7% boys). The use of antibiotics at any stage of pregnancy, and not only in the third trimester, was associated with the occurrence of tonsillitis at four years, even after controlling for potential confounders (OR 1.19, 95% CI 1.03-1.38). Other infections did not show association.

Maternal use of antibiotics during pregnancy was associated with an increased risk of tonsillitis reported at four years of age. Antibiotics could favour the potential transmission of an unfavourable microbiome from mother to child.

Selisistat There is currently no information on the role of the Delta-like homologue 1 (DLK1), a NOTCH inhibitor, in the regulation of renal damage. Here, we investigated the contribution of DLK1 to experimental renal damage and the underlying molecular mechanisms. Using a Dlk1-null mouse model in the experimental renal damage of unilateral ureteral obstruction, we found activation of NOTCH, as shown by increased nuclear translocation of the NOTCH1 intracellular domain, and upregulation of Dlk2/hey-1 expression compared to wild-type (WT) littermates. NOTCH1 over-activation in Dlk1-null injured kidneys was associated with a higher inflammatory response, characterized by infiltration of inflammatory cells, mainly CD4/IL17A + lymphocytes, and activation of the Th17 immune response. Furthermore, pharmacological NOTCH blockade inhibited the transcription factors controlling Th17 differentiation and gene expression of the Th17 effector cytokine IL-17A and other related-inflammatory factors, linked to a diminution of inflammation in the injured kidneys. We propose that the non-canonical NOTCH ligand DLK1 acts as a NOTCH antagonist in renal injury regulating the Th17-mediated inflammatory response.Acute kidney injury (AKI) is a common clinical problem, and patients who survive AKI have a high risk of chronic kidney disease (CKD). The mechanism of CKD post-AKI, characterized by progressive renal fibrosis, is still unclear. Maladaptive tubular epithelial cells (TECs) after AKI are considered a leading cause of renal fibrosis post-AKI. TECs under maladaptive repair manifest characteristics of senescence. Removing senescent TECs by genetic ablation has been proven effective in reducing renal fibrosis. Senolytics, which eliminate senescent cells by pharmacological intervention, have been studied in a series of degenerative diseases. To our knowledge, the effects of senolytics on renal fibrosis post-AKI have not been verified before. Here, we confirmed renal senescence in the unilateral ischemia/reperfusion injury murine model. Senescent TECs could activate fibroblasts and senolytics specifically induced apoptosis of senescent TECs. Next, we demonstrated that senolytics could reduce renal senescence and ameliorate renal fibrosis in both unilateral renal ischemia/reperfusion injury and multiple-cisplatin-treatment murine models. Our results indicate senescent TECs as a vital factor in renal fibrosis progression, and senolytic therapy might be promising for treating CKD post-AKI.
To assess the efficacy of glucagon-like peptide-1 receptor agonists (GLP1-RAs) and sodium-glucose co-transporter 2 (SGLT2) inhibitors, administered without metformin on cardiovascular outcomes in type 2 diabetes patients.

A systematic review was performed according to Cochrane's methodological standards. We included randomized clinical trials (RCTs) on adult type 2 diabetes patients, assessing the efficacy of SGLT2 inhibitors and GLP1-RAs compared to other glucose-lowering drugs and/or RCTs that presented data of a subgroup of type 2 diabetes patients without metformin use at baseline. The main outcome was the reduction of the risk of any major adverse cardiovascular events (MACE) reported individually or as a composite outcome.

Five RCTs including 50,725 type 2 diabetes patients, of whom 10,013 had not received metformin, were included in this meta-analysis. Three of these studies assessed the efficacy of GLP1-RAs and two of SGLT2 inhibitors. In patients without metformin at baseline, GLP1-RAs in comparison with placebo reduced the risk of MACE significantly by 20% (HR 0.80; 95% CI 0.71-0.89). SGLT2 inhibitors also significantly reduced the risk of MACE by 32% (HR 0.68; 95% CI 0.57-0.81).

SGLT2 inhibitors and GLP1-RAs provided without metformin at baseline may reduce the risk of MACE in comparison with placebo in type 2 diabetes patients at increased risk of cardiovascular events.

The role of donor-derived cell-free DNA (dd-cfDNA) in screening for cardiac allograft vasculopathy (CAV) is unknown. We hypothesized that dd-cfDNA correlates with CAV, markers of inflammation, and angiogenesis in stable heart transplant (HT) recipients.

Sixty-five HT recipients ≥2years post-transplant, without recent rejection, were stratified by high (≥0.12%) versus low levels (<0.12%) of dd-cfDNA. A targeted amplification, next-generation sequencing assay (AlloSure
; CareDx, Inc.) was used to detect dd-cfDNA. Peripheral blood inflammatory and angiogenesis markers were assessed using a multiplex immunoassay system (Bioplex
).

Of 65 patients, 58 patients had a known CAV status and were included. Thirty had high levels of dd-cfDNA (≥0.12%), and 28 had low levels (<0.12%). CAV was present in 63% of patients with high dd-cfDNA vs. 35% with low dd-cfDNA (p=.047). Donor-specific antibodies were present in 25% of patients with high dd-cfDNA vs. 3.8% in those with low dd-cfDNA (p=.03). There were no differences in rejection episodes, inflammatory, or angiogenesis markers. Importantly, dd-cfDNA levels were not different when stratified by time post-transplant.

Higher dd-cfDNA levels were associated with CAV in stable chronic HT recipients. Further studies are warranted to investigate a possible association between dd-cfDNA levels and CAV severity and whether dd-cfDNA can predict CAV progression.

To demonstrate the efficacy and safety of mini-percutaneous nephrolithotomy, micro-percutaneous nephrolithotomy, and flexible ureteroscopy for pediatric upper urinary tract calculi and to develop nomograms predicting surgical outcomes.

A prospectively managed database containing children who were diagnosed with upper urinary tract calculi and treated with mini-percutaneous nephrolithotomy, micro-percutaneous nephrolithotomy, and flexible ureteroscopy between June 2014 and April 2019 was analysed. Patient demographics, intraoperative data, stone characteristics, stone-free rate, and complication rate were analysed and compared. Nomograms predicting the postoperative stone-free rate and complication rate were established based on predictors, and internal validation was performed. Calibration curves and decision curves were generated to assess the predictive efficacy and clinical benefit.

Forty-three children underwent mini-percutaneous nephrolithotomy on 56 sides in 47 operations, 30 children underwent mition against threshold probabilities of stone-free rate ≤20% and complication rate ≤10%.

Both the percutaneous nephrolithotomy and flexible ureteroscopy procedures could have acceptable stone-free rates when treating pediatric stones. The Capital Medical University nomograms performed well in helping to predict stone-free and complication rates.

Refractometry is used to assess transfer of passive immunity (TPI), but studies evaluating different refractometers and appropriate thresholds for recommended target immunoglobulin G (IgG) concentrations for beef calves are limited.

To evaluate test performance of digital (DSTP) and optical (OSTP) serum total protein (STP) refractometers and a digital Brix (DBRIX) refractometer for assessment of passive immunity in beef calves.

A total of 398 beef calves from 6 herds, 1 to 7 days of age.

Serum IgG concentration was estimated by DSTP, OSTP, and DBRIX, and measured by radial immunodiffusion (RID). Correlation coefficients (r) among results were calculated. Optimal STP and Brix thresholds for identification of IgG <10, <16, and <24 g/L were determined using interval likelihood ratios. Refractometer performance and agreement were assessed using areas under the curve (AUC), diagnostic test characteristics, Cohen's kappa (κ), and Bland-Altman analysis.

Refractometer results were highly correlated with RID (r = 0.82-0.91) and with each other (r = 0.91-0.95), and overall test performance was excellent (AUC = 0.93-0.99). The STP concentrations of ≤5.1, ≤5.1, and ≤5.7 g/dL and Brix percentages of ≤7.9%, ≤8.3%, and ≤8.7% indicated IgG concentrations <10, <16, and <24 g/L, respectively. Agreement of refractometers with RID was variable (κ = 0.46-0.80) and among refractometers was substantial (κ = 0.62-0.89).

All refractometers showed good utility as monitoring tools for assessment of TPI in beef calves.

A new heart transplantation allocation system was implemented in the United States on October 18, 2018. The effect of the new allocation system on adult congenital patients is unknown. Adult congenital patients listed for transplantation between November 1, 2015 and September 30, 2019 registered in the United Network for Organ Sharing were included in the study. October 18, 2018 was used as the limit to distribute listed and transplanted patients into old and new groups. A total of 399 patients were listed for heart transplant only, 284 in the old system and 115 in the new system. Clinical characteristics were similar between both groups. The cumulative incidence of poor outcome on the transplant list was similar in both groups (P = .23), but the cumulative incidence of transplant was higher in the new system group (P less then .009) and was associated with a shorter waitlist time.
