5 ± 1.5%. We conclude that a treosulfan-based conditioning regimen gives excellent DFS in pediatric HSCT performed for a nonmalignant disorder but with substantial mucosal toxicity. In a malignant disorder a treosulfan-based regimen looks promising but larger, preferably randomized, studies are needed to prove efficacy.D-2-hydroxyglutaric aciduria (D-2-HGA) is a rare metabolic disorder characterized by developmental delay, hypotonia, and bi-allelic mutations in D-2-hydroxyglutarate dehydrogenase (D2HGDH) or a single gain-of-function mutation in isocitrate dehydrogenase 2 (IDH2). Metaphyseal chondromatosis with D-2-hydroxyglutaric aciduria (MC-HGA) is a type of D-2-HGA that has been previously reported in ten patients (OMIM 614875), three of whom had somatic mosaicism for R132 variants in isocitrate dehydrogenase 1 (IDH1). We describe a 3-year-old boy with MC-HGA who subsequently developed acute myeloid leukemia (AML) and was found to have an IDH1 R132C mutation in a leukemic bone marrow sample. Further testing revealed presence of somatic mosaicism for IDH1 R132C variant, suggesting an association of IDH1 in inducing myeloid leukemogenesis.Introduction Supervised exercise may improve physical function and quality of life during oncological treatment. Providing supervised exercise to all patients at hospitals may be impractical, with community-based settings (e.g. public gyms) as a possible alternative. To facilitate implementation, knowledge about the experiences of professionals who deliver exercise programs in community-based settings is crucial.Objective To explore how physical therapists and personal trainers experience supervising exercise in a community-based setting for persons undergoing curative oncological treatment. Methods Nine physical therapists and two personal trainers (coaches) were interviewed individually. The semi-structured interviews lasted 33-67 minutes and were analyzed using thematic analysis. Results Two main themes emerged "A meaningful task" and "A challenging task," with nine sub-themes. The coaches experienced supervising exercise for persons undergoing treatment as meaningful, as they became a link between oncology care and health promotion. They grew more confident in the role and ascertained that exercising during treatment was feasible. Challenges included managing side effects of treatment and contradictory information from oncology care staff at hospitals, advising patients not to exercise.Conclusion Supervising exercise for persons undergoing oncological treatment in a community-based setting may be highly rewarding for professionals who deliver exercise programs, which is promising for implementation. However, patients receive contradictory information about exercise, which may prevent physical activity. Also, supervising exercise for persons undergoing oncological treatment requires skills training; this is suggested for inclusion in educational programs for physical therapists and others. Future research should focus on strategies for cooperation between oncology care and health promotion.Objective In Japan, supplementation with 400 µg of folic acid per day is recommended for women who are planning to get pregnant to decrease the risk of their babies getting neural tube defects (NTD). However, the proportion of women who have taken folic acid supplements before conception is low among Japanese pregnant women. In addition, the dietary intake of folic acid has not yet reached the government recommended dietary intake levels (480 µg per day). This study aimed to clarify the prevalence and determinants of adequate folic acid supplements among Japanese pregnant women with dietary folic acid intake lower than 480 µg per day.Methods This cross-sectional study was a part of the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study. We collected information on folic acid supplements before conception, sociological/lifestyle characteristics, and food consumption. The primary outcome was the use of folic acid supplements (adequate or inadequate, based on the timing of initiation of folic acid supplements). Multiple logistic regression analysis was used to examine the association between sociological/lifestyle characteristics and the adequate intake of folic acid supplements.Results Among the 11,562 pregnant women who took lower than 480 µg per day of folic acid from food, the prevalence of adequate users was 18.0%. Pregnant women who reported adequate use of folic acid supplements were more likely to be older and educated; and reported higher household income, and history of fertility treatment. Conversely, they were less likely to be ever or current smokers and multipara.Conclusion This study found that the prevalence of folic acid supplements use for the prevention of NTD among Japanese pregnant women was still low.In cosmetics and food products, parabens are widely used as antimicrobial agents. Reports have suggested that parabens may be linked to infertility, owing to their effects on basal steroidogenesis properties or their capacity to inflict mitochondrial damage. Despite growing concerns about parabens as endocrine disruptors, it is unclear whether they affect any of these actions in humans, particularly at environmentally relevant concentrations. In this work, an in vitro primary culture of human granulosa cells was used to evaluate steroidogenesis, based on the assessment of progesterone production and regulation of critical steroidogenic genes CYP11A1, HSD3B1, CYP19A1, and HSD17B1. The effects of two commercially relevant parabens, methylparaben (MPB) and butylparaben (BPB), were screened. Cells were exposed to multiple concentrations ranging from relatively low (typical environmental exposure) to relatively high. The effect was assessed by the parabens' ability to modify steroidogenic genes, progesterone or estradiol production, and on mitochondrial health, by evaluating mitochondrial activity as well as mtDNA content. Neither MPB nor BPB showed any effect over progesterone production or the expression of genes controlling steroid production. Only BPB affected the mitochondria, decreasing mtDNA content at supraphysiological concentrations (1000 nM). Prolonged exposure to these compounds produced no effects in neither of these parameters. In conclusion, neither MPB nor BPB significantly affected basal steroidogenesis in granulosa cells. Although evidence supporting paraben toxicity is prevalent, here we put forth evidence that suggests that parabens do not affect basal steroidogenesis in human granulosa cells.Purpose To present the clinical picture and radiological characteristics of orbital manifestations of granulomatosis with polyangiitis in a Mexican hospital and compare them with worldwide literature.Methods Retrospective, observational study from January 2007 to January 2019. An electronic file review was performed. All patients with the diagnosis of granulomatosis with polyangiitis (GPA) in the Oculoplastics department were included. Ophthalmological examination, biopsy, antibodies and tomographical results were included in the data collected. Descriptive statistics were obtained.Results One hundred and one patients in our institute had a diagnosis of GPA. Only 15 (14.8%) had orbital manifestations and were included in our study. 73.3% were female with a median age of 46.20 years (17-81). Diagnostic delay was on average 6 months. Only 6.7% had bilateral manifestations. No past medical history was found in 40%, 20% had a previous diagnosis of systemic GPA. Pain was reported in 73.3%. Increase of volume (proptosis or diffuse orbital mass) was present in 86.7%. C-ANCA antibodies were positive in seven patients (46.7%). In tomography, lacrimal gland involvement was present in 33.3% and diffuse orbital mass was present in 66.6%. Definite diagnosis was done with biopsy in 93.3%. One patient died from complications of GPA.Conclusions Ophthalmologists should consider this rare disease as a differential diagnosis of orbital tumors, as it may have different clinical manifestations, even in non-Caucasian population. When in doubt, biopsy is always valuable. The statistics at our reference center correspond with statistics reported worldwide.Introduction The application of artificial intelligence (AI) and machine learning (ML) in medicine and in particular in respiratory medicine is an increasingly relevant topic.Areas covered We aimed to identify and describe the studies published on the use of AI and ML in the field of respiratory diseases. The string '(((pulmonary) OR respiratory)) AND ((artificial intelligence) OR machine learning)' was used in PubMed as a search strategy. The majority of studies identified corresponded to the area of chronic obstructive pulmonary disease (COPD), in particular to COPD and chest computed tomography scans, interpretation of pulmonary function tests, exacerbations and treatment. Another field of interest is the application of AI and ML to the diagnosis of interstitial lung disease, and a few other studies were identified on the fields of mechanical ventilation, interpretation of images on chest X-ray and diagnosis of bronchial asthma.Expert opinion ML may help to make clinical decisions but will not replace the physician completely. Human errors in medicine are associated with large financial losses, and many of them could be prevented with the help of AI and ML. AI is particularly useful in the absence of conclusive evidence of decision-making.The in situ hydrogel drug delivery system is a hot research topic in recent years. selleck chemicals llc Combining both properties of hydrogel and solution, in situ hydrogels can provide many advantages for drug delivery application, including easy application, high local drug concentration, prolonged drug retention time, reduced drug dose in vivo, good biocompatibility and improved patient compliance, thus has potential in tumor treatment. In this paper, the related literature reports in recent years were reviewed to summarize and discuss the research progress and development prospects in the application of in situ hydrogels in tumor treatment.Growing evidence points at an association between microRNAs and tumor development. Although dysregulation of microRNA-103a-3p (miR-103a-3p) in multiple human cancers has been reported, its expression in prostate cancer (PCa) remains unknown and there is currently no research on the relationship between miR-103a-3p and tumor protein D52 (TPD52) in PCa. Our aim in this study was to explore the effect and potential mechanism of miR-103a-3p in PCa. qRT-PCR was performed to detected the level of miR-103a-3p in PCa tissues and cells, and in normal tissues. Colony, wound-healing, invasion, proliferation, and apoptosis assays were performed in search miR-103a-3p effect in PCa. TargetScan was used to predict potential targets of miR-103a-3p. Additionally, dual-luciferase reporter, western blot, and immunofluorescence assays were performed to detected the target gene of miR-103a-3p. Finally, we explore the differences in tumor xenograft experiments between nude mice injected with stably miR-103a-3p expressing cells and those expressing a miR-negative control. Low level of miR-103a-3p was detected in PCa tissues and cells, when compared with normal tissues. Enhancement of miR-103a-3p significantly inhibited migration and invasion of PCa cells, and negatively regulated expression of the oncogenic tumor protein D52 (TPD52) through direct binding to its 3'-UTR. Interestingly, overexpression of TPD52 significantly attenuated the effect of mir-103a-3p on PCa. Our study provides the first evidence that miR-103a-3p directly targets TPD52 and inhibits the proliferation and invasion of PCa. This finding helps clarify the role of mir-103a-3p-TPD52 axis in PCa and may provide new therapeutic targets for the disease.
