Indeed, these are exciting times for both pediatric patients with Gaucher disease and those with other lysosomal storage disorders.

For pediatric patients with non-neuronopathic Gaucher disease, there may be new therapeutic options on the horizon in the form of gene therapy or small molecule glucocerebrosidase chaperones. These have the potential to result in a cure for systemic disease manifestations and/or to reduce the cost and convenience of treatment. For children with neuronopathic Gaucher disease, the challenge of targeting therapy to the central nervous system is being explored through new modalities including brain-targeted gene therapy, in-utero therapy, brain-penetrant small molecule chaperones, and other methods that convey enzyme across the blood-brain barrier. Indeed, these are exciting times for both pediatric patients with Gaucher disease and those with other lysosomal storage disorders.AML with mutated NPM1 occurs in all age groups. Yet, the mutational pattern is not extensively studied in the very old, which may hamper appropriate risk assessment. Herein we examined 22 cases of NPM1-mutated de novo AML in patients older than 75, with a median age of 84. All diagnostic samples were sequenced aiming for coverage of the most relevant AML-associated mutations. For comparison with younger patients, we used already published data on several cohorts. A total of 76 mutations including 50 different variants were identified in 16 recurrently mutated AML genes. Compared with younger patients, a significant enrichment of TET2 and SRSF2 was observed, together with a reduced frequency of DNMT3A mutations. Our results indicate that the mutational pattern may be different in the very old as compared to younger patients with NPM1-mutated AML.HighlightsThe mutational spectrum of NPM1-mutated AML in patients above 75 years displays distinct features.A significant enrichment of TET2 and SRSF2 mutations together with a reduced frequency of DNMT3A mutations was observed in the elderly.NPM1 mutation is a secondary event in the development of AML in the very old.There is abundant evidence in the literature to show that victimization has a series of adverse consequences on child victims' physical and mental health. However, some studies detailed whether the family correlates of repeat victims differ from those who are victimized only once. This study fills this gap by describing the probabilities that children who fit certain profiles will be repeat victims and implies that it is possible to identify and screen individual and family factors who are at high risk of repeated victimization. Using the 2009-2010 Child Victimization Survey, we analyzed data from 14,564 Chinese adolescents aged 14-18 years from five major cities in China. We employed a multinomial logit regression model, using child victimization as the dependent variable and demographic factors as independent variables. We identified the top 1% of the most vulnerable cases and summarized their demographic characteristics. Our analysis revealed that older boys with siblings in the same household whose mothers' education was below average were the most vulnerable to one-time victimization. Further, boys with siblings whose parents were less-educated than average, unemployed, and unmarried were the most vulnerable to repeated victimization. This study has vast practical implications, including different ways to confront the problem of repeated child victimization (both practically and in the literature), develop a quick screening tool, and apply cost-effective prevention and interventions in China.Acute promyelocytic leukemia (APL) boasts overall survival (OS) of >90% at 3 years and early mortality of 60 years. OS at 1- and 3-year were 81% and 75%, respectively. In a multivariate analysis, age ≤ 40 years, treatment at academic center, use of multi-agent therapy, and diagnosis after 2009 conferred better OS. In this largest database study in APL till date, we demonstrated an overall improvement in OS over time but challenges still exist in translating successes of clinical trials to real-world practices.A Pd-catalyzed hydrothiocarbonylation of unactivated terminal alkenes is presented. According to this protocol, aliphatic thioesters were synthesized with exclusive linear selectivity under mild reaction conditions. Good to excellent yields (up to 91% yield), broad substrate scope, broad functional group tolerance, and utility of the method demonstrated the advantages of this protocol.Herein, the first Cp*Co(III)-catalyzed C-H allylation of ferrocene thioamides with allyl carbonates has been developed. This reaction is compatible with a wide range of functional groups, providing various allylated ferrocene derivatives in up to 90% yields. In addition, the C-H allylation protocol is also compatible with the use of vinylcyclopropanes as allylating reagents by merging C-H and C-C activation into one catalytic system. Mechanistic studies revealed that the thiocarbonyl-directing group plays a vital role in C-H activation.One-dimensional materials have been intensively studied because of their diverse properties, which are revealed when exfoliated from their bulk precursor. Liquid exfoliation is not only possibly the most suitable method for large-scale applications but also affords an opportunity to develop new deposition techniques. Fibrous phosphorus is a relatively new, one-dimensional material with high carrier mobility and a fast response velocity for future application in nanodevices. Because controllable liquid exfoliation processing of fibrous phosphorus (FP) remains challenging, we considered two factors the exfoliated result and the removable solvents. We proposed a method for determining suitable solvents for efficient exfoliation and controllable size of fibrous phosphorus using Hansen solubility parameters. Nintedanib clinical trial By controlling the water/acetone mixture ratios, the exfoliation effect could be controlled. Our work showed that 40% of the FP nanofibers were less than 10 nm in thickness and 70% of them were less than 20 nm. Furthermore, fibrous phosphorus produced a red fluorescence in bioimaging.Aside from their canonical role in hemostasis, it is increasingly recognized that platelets have inflammatory functions and can regulate both adaptive and innate immune responses. The main topic this review aims to cover is the proinflammatory effects and side effects of platelet transfusion. Platelets prepared for transfusion are subject to stress injury upon collection, preparation, and storage. With these types of stress, they undergo morphologic, metabolic, and functional modulations which are likely to induce platelet activation and the release of biological response modifiers (BRMs). As a consequence, platelet concentrates (PCs) accumulate BRMs during processing and storage, and these BRMs are ultimately transfused alongside platelets. It has been shown that BRMs present in PCs can induce immune responses and posttransfusion reactions in the transfusion recipient. Several recent reports within the transfusion literature have investigated the concept of platelets as immune cells. Nevertheless, current and future investigations will face the challenge of encompassing the immunological role of platelets in the scope of transfusion.Patients with asthma should be vaccinated against COVID-19. This includes patients with severe asthma. Treatment with a biological for asthma is no contra-indication for vaccination against COVID-19.Jean-Nicolas Corvisart des Marets (1755-1821) was the personal physician of the Emperor Napoleon I. He was one of the leading french physicians to promote and teach clinical and anatomical medicine. Corvisart was a pioneer of modern cardiology. He became famous by his contribution to the development and popularization of the chest percussion technique of Leopold Auenbrugger (1722-1809).

Tacrolimus is an immunosuppressive drug. Activation of the renin-angiotensin system (RAS) and associated inflammations may exacerbate the toxic effects of tacrolimus. Given the significant role of the kidney in RAS this study aimed to evaluate the effect of captopril as an angiotensin-converting enzyme (ACE) blocker and losartan as an angiotensin II receptor blocker on tacrolimus-induced nephrotoxicity.

In total, 36 adult male rats weighing 200-250 gr were completely randomized and divided into six groups (control, tacrolimus, tacrolimus and losartan, tacrolimus and captopril, losartan, and captopril) for 30 days. Afterwards, blood urea nitrogen (BUN), creatinine (Cr) and ACE2 enzyme were measured. Also, both kidneys were collected for histological examinations.

The level of BUN and Cr significantly increased in tacrolimus group. The level of BUN and Cr were lower in the groups treated with a combination of tacrolimus and losartan or captopril. While ACE2 level increased in the groups receiving a combination of tacrolimus and losartan or captopril, the level of increase was insignificant, compared to the group treated with tacrolimus alone. The glomerulus diameter and the thickness of the renal proximal tubular epithelium significantly decreased in the group treated with tacrolimus alone. the mentioned variables increased in the group treated with a combination of tacrolimus and losartan or captopril, compared to the tacrolimus group.

According to this study, tacrolimus increased the BUN and Cr levels while decreasing the ACE2 levels. However, tacrolimus in combination with losartan or captopril seemed to decrease the nephrotoxicity of the drug.

 The infection risk during dental procedures is a common concern for dental professionals which has increased due to coronavirus (severe acute respiratory syndrome coronavirus 2) pandemic. The development of devices to specifically mitigate cross-contamination by droplet/splatter is crucial to stop infection transmission. The objective of this study is to assess the effectiveness of a perioral suction device (Oral BioFilter, OBF) to reduce biological contamination spread during dental procedures.

 Forty patients were randomized 11 to a standard professional dental hygiene treatment with OBF and without. Adenosine triphosphate (ATP) bioluminescence assay was used to evaluate the spread of potential contaminants. The total number of relative light units (RLU) from key dental operatory locations operator's face-shield, back of the surgical operator's-gloves, patient's safety-goggles, and instrumental table were measured. Percentage contamination reductions between control and OBF were compared.
