Taking together, these results provide new insight to ameliorate resistance to SG-ARIs and improve treatment outcome.Identification of pediatric patients with acute myeloid leukemia (AML) candidates to receive allogeneic hematopoietic stem cell transplantation (allo-HSCT) in first complete remission (CR1) is still a matter of debate. Currently, transplantation is reserved to patients considered at high risk of relapse based on cytogenetics, molecular biology, and minimal residual disease (MRD) assessment. However, no randomized clinical trial exists in the literature comparing transplantation with other types of consolidation therapy. Here, we provide an up-to-date meta-analysis of studies comparing allo-HSCT in CR1 with chemotherapy alone as a post-remission treatment in high-risk pediatric AML. The literature search strategy identified 10 cohorts from 9 studies performing as-treated analysis. The quantitative synthesis showed improved overall survival (OS) (relative risk, 1.15; 95% confidence interval [CI], 1.06-1.24; P = 0.0006) and disease-free survival (relative risk, 1.31; 95% CI, 1.17-1.47; P = 0.0001) in the allo-HSCT group, with increased relapse rate in the chemotherapy group (relative risk, 1.26; 95% CI, 1.07-1.49; P = 0.006). Sensitivity analysis including prospective studies alone and excluding studies that reported the comparison only on intermediate-risk patients confirmed the benefit of allo-HSCT on OS. Further research should focus on individualizing allo-HSCT indications based on molecular stratification and MRD monitoring.Common outdoor air pollutants present threats to fetal and neonatal health, placing neonatal-perinatal clinical specialists in an important role for harm reduction through patient counseling and advocacy. Climate change is intertwined with air pollution and influences air quality. There is increasing evidence demonstrating the unique vulnerability in the development of adverse health consequences from exposures during the preconception, prenatal, and early postnatal periods, as well as promising indications that policies aimed at addressing these toxicants have improved birth outcomes. Advocacy by neonatal-perinatal providers articulating the potential impact of pollutants on newborns and mothers is essential to promoting improvements in air quality and reducing exposures. The goal of this review is to update neonatal-perinatal clinical specialists on the key ambient air pollutants of concern, their sources and health effects, and to outline strategies for protecting patients and communities from documented adverse health consequences.
The cerebroplacental ratio (CPR) is associated with adverse perinatal outcome (APO) in low-risk pregnancies near term. A Doppler parameter, which also includes information from the uterine vessels could potentially improve detection of subclinical placental dysfunction. The aim of this study is to investigate the performance of cerebro-placental-uterine ratio (CPUR) related to APO prediction in low-risk term pregnancies in > 40 + 0weeks.

This is a retrospective cohort study. All low-risk pregnancies in which feto-maternal Doppler was examined from 40 + 0weeks and an appropriate for gestational age fetus was present were included. ROC (receiver operating characteristic curves) analyses were performed to assess the predictive value of CPUR. The presence of at least one of the following outcome parameters was defined as composite APO (CAPO) operative delivery (OD) due to intrapartum fetal compromise (IFC), admission to the neonatal intensive care unit, umbilical cord arterial pH ≤ 7.15, 5min APGAR ≤ 7.

A total of n = 114 cases were included. Mean gestational age at examination and delivery were 40 + 3weeks and 40 + 6weeks, respectively. Overall, CAPO occurred in 38 of 114 cases (33.3%). ROC analyses showed a significant association of CPUR (AUC = 0.67, p = 0.004) and CPR (AUC = 0.68, p = 0.002) with CAPO. Additionally, CPUR (AUC = 0.64, p = 0.040) showed a predictive value for OD due to IFC.

The CPUR in > 40 + 0weeks showed a predictive value for CAPO and OD due to IFC in low-risk pregnancies. However, the extent to which CPUR can be used to optimize delivery management warrants further investigations in prospective interventional studies.

This process is light-induced and relies on the orchestrated transcription of nuclear and plastid genes, enabling the effective assembly and regulation of the photosynthetic machinery. Here we reveal a new regulation level for this process by showing the involvement of chromatin remodelling in the nuclear control of plastid gene expression for proper chloroplast biogenesis and function. The two Arabidopsis homologues of yeast EPL1 protein, components of the NuA4 histone acetyltransferase complex, are essential for plastid transcription and correct chloroplast development and performance. We show that EPL1 proteins are light-regulated and necessary for concerted expression of nuclear genes encoding most components of chloroplast transcriptional machinery, directly mediating H4K5ac deposition at these loci and promoting the expression of plastid genes required for chloroplast biogenesis. These data unveil a NuA4-mediated mechanism regulating chloroplast biogenesis that links the transcription of nuclear and plastid genomes during chloroplast development.Engineering the plastid genome based on homologous recombination is well developed in a few model species. Homologous recombination is also the rule in mitochondria, but transformation of the mitochondrial genome has not been realized in the absence of selective markers. The application of transcription activator-like (TAL) effector-based tools brought about a dramatic change because they can be deployed from nuclear genes and targeted to plastids or mitochondria by an N-terminal targeting sequence. Recognition of the target site in the organellar genomes is ensured by the modular assembly of TALE repeats. In this paper, I review the applications of TAL effector nucleases and TAL effector cytidine deaminases for gene deletion, base editing and mutagenesis in plastids and mitochondria. I also review emerging technologies such as post-transcriptional RNA modification to regulate gene expression, Agrobacterium- and nanoparticle-mediated organellar genome transformation, and self-replicating organellar vectors as production platforms.
The use of dual mobility cups (DMC) has been shown to reduce hip instability after revision surgery. For severe acetabular bone loss, reconstruction with a Kerboull cross-plate and bone allograft would contribute to restoring native hip position and bone stock. Only two papers reported on the combination of Kerboull cross-plate with bone allograft and cemented DMC in revision total hip arthroplasty (THA).

This is a monocentric retrospective study (28 cases) of first-time revision THA using such a construct in American Association of Orthopaedic Surgeons (AAOS) grade III and IV acetabular bone defect. Detailed demographic, clinical and radiographic results were recorded and evaluated.

With a mean follow-up of six ± 3.63years, no case of instability was reported. The modified Harris Hip Score (mHHS) was 88.4 ± 10.1. No hook fracture or mechanical failure was observed. Non-progressive radiolucent lines were recorded. Osteointegration of the allografts was observed in all cases with a mean Grodet score of 7.9 ± 0.97.

In first revision THA, the use of a Kerboull cross-plate with allograft and a cemented DMC in AAOS grade III and IV acetabular bone defects demonstrated excellent clinical and radiological outcomes with no recorded cases of dislocation or mechanical failure.

MRI measures of pure multifidus muscle cross-sectional area (CSA) were acquired from 522 patients presenting with low back and/or leg symptoms in an outpatient clinic. We explored cross-sectional associations between the presence, distribution, and/or severity of lumbar degenerative pathologies (individually and in aggregate) and muscle outcomes in multivariable analyses (beta coefficients [95% CI]). We identified associations between lower pure multifidus muscle CSA and disc degeneration (at two or more levels) - 4.51 [- 6.72; - 2.3], Modic 2 changes - 4.06 [- 6.09; - 2.04], endplate defects - 2.74 [- 4.58; - 0.91], facet arthrosis - 4.02 [- 6.26; - 1.78], disc herniations - 3.66 [- 5.8; - 1.52], and when > 5 pathologies were present - 6.77 [- 9.76; - 3.77], with the last supporting a potential dose-response relationship between number of spinal pathologies and multifidus morphology. Our findings could hypothetically indicate that these spinal and muscle findings (1) are part of the same degenerative process, (2) result from prior injury or other common antecedent events, or (3) have a directional relationship. Future longitudinal studies are needed to further examine the complex nature of these relationships.
The main objective of this retrospective study was to establish an epidemiological overview of patients admitted to an Emergency department specialized in musculo-skeletal trauma for acute lesions related to Badminton practice in the period from January 1st 2010 to January 1st 2015.

There were 135 patients with 140 admissions and 146 total number of injuries. There were 67 females (48%) and 73 males (52%). The mean age was 28 ± 13.8years, ranging 10-66years. 91 patients (65%) could be contacted by telephone to fill a questionnaire aimed at completing the information provided by the medical records.

129 lesions (88.3%) were located to the lower limbs, 16 (11%) to the upper limbs, and one (0.7%) at the head. For the whole series, there were 89 sprains (60.9%), 32 tendino-muscular lesions (21.9%), 13 fractures (8.9%), 5 dislocations (3.4%), 3 painful contusions (2.1%), 3 meniscal injuries (2.1%) and one wound (0.7%). In the lower limbs, lateral ankle sprain was the most frequent diagnosis (43.4%), followed successively by rupture of the Achilles tendon (13.9%), tennis leg (8.5%), and mid-foot sprain (6.9%). Of the 146 lesions, 117 (80.1%) received non-operative treatment, 28 (19.1%) received surgical treatment in the operation room, and one simple wound (0.7%) was sutured in the emergency room.

Lateral ankle sprains followed by tendino-muscular lesions of the calf are by far the most frequent lesions of badminton. Modification of the shoes of badminton players should be considered to decrease the high incidence of ankle injuries.
