Evaluation of maternal health and labor and delivery conditions as risk factors for childhood leukemias in children with Down syndrome

Publication date: February 2017 Source:Cancer Epidemiology, Volume 46 Author(s): Susan E. Carozza, Harold Bae, Thomas Meath, Adam Branscum, Marit L. Bovbjerg, Peter H. Langlois Children with Down syndrome (DS) have a remarkably high risk of developing leukemia during childhood; the mechanisms driving that risk are not well understood, and no clear prevention strategies exist. We conducted a nested case-control study in a Texas DS birth cohort to investigate possible links between maternal health, labor/delivery conditions, and leukemia risk. For most of the factors studied there was no evidence of an increased risk of total leukemias, or the subtypes acute lymphoid or acute myeloid leukemia. Ultrasound use showed an almost 2-fold increased odds of leukemia, but this result is likely an example of confounding by indication. There was a pattern of increased risk seen for presence of co-occurring heart anomalies, including tetralogy of Fallot, ventricular septal defects, atrial septal defects, and patent ductus arteriosus. Further investigation of the links between co-occurring heart defects in children with DS and development of leukemia may provide new understanding of cancer mechanisms, and ultimately lead to prevention opportunities for this high-risk population.

AbstractThree BODIPY ‐peptide conjugates designed to target the epidermal growth factor receptor (EGFR) at the extracellular domain were synthesized and their specificity for binding to EGFR was investigated. Peptide sequences containing seven amino acids, GLARLLT (2) and KLARLLT (3), and 13 amino acids, GYHWYGYTPQNVI (4), were conjugated to carboxyl BODIPY dye (1) by amide bond formation in up to 73% yields. The BODIPY ‐peptide conjugates and their “parent” peptides were determined to bind to EGFR experimentally using SPR analysis, and were further investigated using computational methods (AUTODOCK).

CONCLUSIONS: GC treatment has implications in CVR, despite in SSc GC doses administered are lower than in other autoimmune diseases (in our cohort even prednisone ≤10 mg daily was associated with ED). GC may be associated with an early vascular damage in these patients, which could lead to changes in FMD, ED and finally AP. On the other hand, optimum levels of 25(OH)D3 seemed to be beneficial against vascular damage. PMID: 32083542 [PubMed - as supplied by publisher]

CONCLUSIONS: Patients with axSpA are more likely to be reclassified into the very-high risk category after carotid ultrasound than controls. The influence of traditional cardiovascular risk factors on this reclassification differs between patients and controls. PMID: 32083538 [PubMed - as supplied by publisher]

ConclusionCompounds 1, 2, 5, and 6 showed anti-prostate cancer activities using the LNCaP prostate cancer cells with IC50 values of 17.84, 33.26, 54.13, and 81.55 μg/mL, and compounds 3, 4, 8, and 9 exhibited moderate hepatoprotective activities, respectively. A preliminary structure-activity relation was summarized in this paper.Graphical abstract

Authors: Gholami A, Mousavi SM, Hashemi SA, Ghasemi Y, Chiang WH, Parvin N Abstract Nowadays, magnetic nanoparticles (MNPs) have been rapidly investigated and attracted worldwide attention due to their great potential as mediators of heat for treating hyperthermia and their possibility to deliver drugs at specific locations, which can thereby limit systematic effects. Cancer therapy via MNPs proposes novel properties rather than normal methods such as almost zero side effects and a high-efficiency rate of effectiveness. The key aim of targeted drug delivery is to reduce side effects of the main cancer treatment tha...

Authors: Zeng Q, Zhao L, Wang C, Gao M, Han X, Chen C, Tu C, Han P, Li J Abstract Background: A high prevalence of autoimmune thyroid disease (AITD) has been observed in patients with autoimmune liver disease (AILD); however, data on the clinical relationship between AILD and AITD remain scant. We aimed to evaluate the relationship between AILD and AITD.Methods: We performed a retrospective study using medical records from 324 patients with AILD, 113 of whom had concurrent AITD.Results: Patients with autoimmune hepatitis (AIH) were more likely to develop AITD (45.8%), followed by autoimmune hepatitis-primary biliar...

In this study we tried to explore Diazepam as a repurposed drug and tested it in Neuroblastoma (Neuro 2a) cells. Diazepam loaded Poly Lactic Acid Nanoparticles were developed (D-PLA-NPs) using nanoprecipitation method. Entrapment efficiency was found to be ± 99.7% and drug loading was ± 12.88%. The particle size developed was 188.8 nm and zeta potential was −25.6 millivolt. Dissolution profiles were studied in PBS (pH 7.4) or simulated media, almost 50% release was observed within 6 h. In vitro, cytotoxicity was analyzed using MTT assay where dose-dependent cytotoxicity was observed for developed D-PLA-NPs.
