Wilms tumor (WT) is a curable type of cancer with 5-year survival rates of over 90% in high-income countries, whereas this is less than 50% in low- and middle-income countries. We assessed treatment outcomes of children with WT treated at a large Kenyan teaching and referral hospital.

We conducted a retrospective record review of children diagnosed with WT between 2013 and 2016. Treatment protocol consisted of 6weeks of preoperative chemotherapy and surgery, and 4-18weeks of postoperative chemotherapy depending on disease stage. Probability of event-free survival (pEFS) and overall survival (pOS) was assessed using Kaplan-Meier method with Cox regression analysis. Competing events were analyzed with cumulative incidences and Fine-Gray regression analysis.

Of the 92 diagnosed patients, 69% presented with high-stage disease. Two-year observed EFS and OS were, respectively, 43.5% and 67%. Twenty-seven percent of children died, 19% abandoned treatment, and 11% suffered from progressive or relapsed disease. working on earlier diagnosis strategies.Acrolein is a ubiquitous environmental pollutant that produced by the incomplete combustion of cigarette smoke, forest fires, petroleum fuels, plastic materials, and cooking fumes. Inhalation is a common form of people exposure to acrolein, increasing evidence demonstrates that acrolein impairs the cardiovascular system by targeting vascular endothelial cells. However, the molecular mechanism of the cytotoxicity of acrolein exposure on vascular endothelial cells remains unclear. This work focused on the toxicity of acrolein on human umbilical vein endothelial cells (HUVECs). The molecular mechanism was studied based on oxidative stress, DNA damage response (DDR), and mitochondrial apoptosis pathways. After HUVECs were treated with 12.5, 25, and 50 μM acrolein for 24 h, cell viability, cell colony formation, mitochondrial membrane potential, and adenosine triphosphate content significantly reduced, and acrolein increased intracellular reactive oxygen species, apoptosis rate, and 8-hydroxy-2 deoxyguanosine (8-OHdG) level. Furthermore, p38MAPK and c-Jun N-terminal kinase signaling pathways were activated in response to oxidative stress. Moreover, acrolein induced G0/G1phase arrest, promoted the expression of γ-H2AX, activated the DDR signaling pathway (Ataxia-Telangiectasia-Mutated [ATM] and Rad-3-related/Chk1 and ATM/Chk2), and triggered the consequent cell cycle checkpoints. Finally, the protein expression of Bax/Bcl-2 and cleaved Caspase-3 was up-regulated, suggesting apoptosis was induced by triggering the mitochondrial apoptosis pathway. All these results indicated that acrolein induced HUVECs cytotoxicity by regulating oxidative stress, DNA damage, and apoptosis. This study provides a novel perspective on the mechanism of acrolein-induced cardiovascular toxicity, it will be helpful for the prevention of acrolein-induced cardiovascular disease.
The sodium-glucose co-transporter 2 inhibitor empagliflozin reduced the total burden of cardiovascular, mortality, and all-cause hospitalization events, including first and recurrent events, in EMPA-REG OUTCOME participants with type 2 diabetes (T2D) and established atherosclerotic cardiovascular disease (ASCVD). We investigated the effect of empagliflozin on the total burden of cardiovascular and hospitalization events in Asian participants.

Participants were randomized to empagliflozin 10 mg, 25 mg or placebo plus standard of care. The primary and key secondary outcomes were the composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke and the primary outcome plus hospitalization for unstable angina, respectively. The effect of pooled empagliflozin versus placebo on total (first plus recurrent) cardiovascular and hospitalization events was analysed using a negative binomial model that preserves randomization and accounts for within-patient correlation of multiple events. Wed ASCVD, consistent with the overall trial population.
This study reports cancer incidence and survival among Aboriginal and Torres Strait Islander children and other Australian children, and assesses changes over time.

Data were from the population-based Australian Childhood Cancer Registry. The study comprised children aged under 15 diagnosed between 1997 and 2016 and with mortality follow-up until 31 December 2017. Incidence trends were analysed using JoinPoint regression. Five-year cancer-specific survival was calculated using the semi-complete approach with survival comparisons made using multivariable flexible parametric models.

Aboriginal and Torres Strait Islander children accounted for 506 of 13,299 eligible cases (3.8%). Incidence rates for Aboriginal and Torres Strait Islander children across the study period increased by 2.3% annually (95% confidence interval [CI] +0.6% to +4.0%) and for other Australian children increased by 0.6% annually (95% CI +0.3% to +0.9%; p = .05). Nonetheless, cancer incidence was consistently lower for Aboriginal and Torres Strait Islander children, with an incidence rate ratio of 0.73 (95% CI 0.62-0.85; p<.01) between 2012 and 2016. Survival for Aboriginal and Torres Strait Islander children with solid tumours was 70.6% (95% CI 62.5%-77.3%) and for other Australian children was 83.5% (95% CI 82.3%-84.7%; p < .01), with indications of this difference diminishing in recent years.

Improvements in identification, particularly in urban areas, most likely accounts for the greater increase in cancer incidence rates among Aboriginal and Torres Strait Islander children. Examination of data on stage at diagnosis and treatment may provide important insights into survival for children with solid tumours.

Devastating plant virus diseases leading to bad harvests and lower quality of crops have made feeding the beyond seven billion population a huge challenge. Nevertheless, growing resistance and cross resistance of crop protection agents have made this challenge harder. Therefore, an efficient crop protection agent with novel structure and mode of action showing higher efficiency and eco-friendly is urgently needed.

The coat protein (CP) of a virus is a potential target for the discovery of new antiviral agents. Antiviral molecules can inhibit infection by obstructing the assembly of virus particles. A series of novel phthalamide-like thiourea derivatives containing trifluoromethylpyridine was designed and synthesized. Most of the compounds exhibited good antiviral activity against tobacco mosaic virus (TMV). Compound 7b showed notable curative, protective and inactivation activities against TMV. Its inactivation half-maximal effective concentration (EC
) value (20.5μg mL
) was better even than commercial ningnanmycin (23.2μg mL
). Compound 7b also had stronger TMV-CP binding ability than ningnanmycin and destroyed the external shape of TMV particles and hindered the self-assembly of TMV-CP and TMV-RNA.

These phthalamide-like thiourea derivatives especially compound 7b containing trifluoromethylpyridine are potential lead compounds and inhibitors of TMV particle self-assembly.

They cannot be effectively removed by conventional dialysis therapies due to their high albumin binding affinity. Our previous research revealed that cationic liposomes (i.e., polyethyleneimine [PEI]-decorated liposomes) could enhance the clearance of PBUTs via electrostatic interactions. However, the poor biocompatibility (hemolysis) restricted their applications in clinical dialysis treatment. Herein, we produced PEI-anchored, linoleic acid-decorated liposomes (CP-LA liposomes) via the conjugation of PEI to cholesterol chloroformate (Chol-PEI, CP), and linoleic acid (LA) was added to provide liposomal colloidal stability. The CP-LA liposomes outperformed the plain liposomes, demonstrating significantly higher PBUT binding rates and removal rates. In addition, in vitro dialysis simulation verified that the CP-LA liposomes had a better capacity for PBUT clearance than the plain liposomes, especially for PBUTs with a strong negative net charge. Hemolysis and cytotoxicity tests revealed that the biocompatibility of the CP-LA liposomes was better than that of the physically-decorated PEI-liposome. CP-LA liposomes possess great potential for PBUT clearance in clinical dialysis therapy.22q11.2 Deletion Syndrome (22q11DS) is a genetic syndrome caused by a chromosomal microdeletion. It affects approximately 1 in 850-992 pregnancies, and its clinical manifestations include congenital heart disease, gastrointestinal symptoms, and psychiatric illnesses. The study examined the relationship between adaptive behavior and functional outcomes, educational attainment, employment, and independent living, and whether age, gender, intellectual disability, presence of psychiatric disorder, and close friendships could predict levels of adaptive behavior. Parents of adults with 22q11DS (n = 101; 48 male and 54 female) completed the Waisman Activities of Daily Living Scale, demographic details, and questions elicited employment, education, and relationships status. Analysis conducted in SPSS, included descriptive statistics, measures of association, Analysis of Variance, logistic and linear regressions. Epigenetic inhibitor Differences in levels of overall adaptive behavior were found regarding employment and living status, but not in educational attainment. Having close friendships was associated with adaptive behavior as well as the likelihood of living independently. Further research is needed, ideally using prospective designs and purposive sampling strategies. This needs to examine how social and communication deficits impact relationship building and how they are affected by the clinical manifestations of 22q11DS. It also needs to focus on how different social structures interface with levels of adaptive behavior.Obesity is a major global health problem leading to serious complications. It has been consistently associated with alterations in brain structure. Diffusion tensor imaging is used to examine brain white matter microstructure by assessing the dynamics of water diffusion in white matter tracts. Fractional anisotropy and mean diffusivity are two parameters measuring the directionality and rate of diffusion, respectively. Changes in these indices associated with obesity have been previously reported in numerous fiber tracts. This systematic review investigates microstructural white matter alterations in obesity using diffusion tensor imaging. A computerized search was performed in PubMed, Web of Science, and Livivo databases. Based on the inclusion/exclusion criteria, 31 cross-sectional studies comparing individuals with obesity and lean controls were identified. The studies included mixed-gender samples of children, young, middle-aged, and older adults. The majority of included studies reported decreased fractional anisotropy and increased mean diffusivity associated with elevated body mass index, suggesting white matter abnormalities.
