Busulfan and cyclophosphamide (BuCy) is a frequently used myeloablative conditioning regimen for allogeneic hematopoietic cell transplantation (allo-HCT). Theoretical considerations and pharmacological data indicate that application of busulfan prior to subsequent cyclophosphamide (BuCy) may trigger liver toxicity. Reversing the order of application to cyclophosphamide-busulfan (CyBu) might be preferable, a hypothesis supported by animal data and retrospective studies. We performed a prospective randomized trial to determine impact of order of application of Bu and Cy before allo-HCT in 70 patients with hematological malignancy, 33 patients received BuCy and 37 CyBu for conditioning. In the short term, there were minimal differences in liver toxicity favoring CyBu over BuCy, significant only for alanine amino transferase at day 30 (p = 0.03). With longer follow-up at 4 years, non-relapse mortality (6% versus 27%, p = 0.05) was lower and survival (63% versus 43%, p = 0.06) was higher with CyBu compared to BuCy. Other outcomes, such as engraftment (p = 0.21), acute and chronic graft-versus-host disease (p = 0.40; 0.36), and relapse (p = 0.79), were similar in both groups. We prospectively show evidence that the order of application of Cy and Bu in myeloablative conditioning in allo-HCT patients has impact on outcome.The microsampling workshop generated recommendations pertaining to blood sampling site (venous blood versus capillary blood), when to conduct a bridging study, statistical approaches to establish correlation/concordance and deciding on sample size, opportunities and challenges with patient-centric sampling, and how microsampling technology can enrich clinical drug development. Overall, the goal was to provide clarity and recommendations and enable the broader adoption of microsampling supporting patients' needs, convenience, and the transformation from clinic-centric to patient-centric drug development. The need and adoption of away-from-clinic sampling techniques has become critical to maintain patient safety during the current COVID-19 pandemic.In the USA, efforts to improve unequal infant health outcomes require knowledge about how the relationship between education and infant health varies by parental gender and race/ethnicity. Drawing from a pooled random sample of over 1 million live births from the 2011 to 2017 National Vital Statistics System data, we examine the relationship between maternal and paternal education and infant health and assess how it varies by maternal racial and ethnic background. The model fit statistics suggest that the relationship between paternal education and infant health is about equal to maternal education and infant health. However, we find a weaker relationship overall between parental education and infant health among Asian and Hispanic fathers than Whites, American Indian, and Black fathers. Ridaforolimus solubility dmso Black fathers' education is more strongly associated with infant health than that of Black mothers. At some levels, paternal education is also more strongly related to health among Hispanic infants. The results suggest a greater focus on fathers' contributions to infant health is warranted, and programs or policies that focus on fathers could help address racial and ethnic infant health disparities.
To determine whether maternal age has an impact on monozygotic twinning (MZT) rates in women undergoing single embryo transfer (SET).
This is a retrospective cohort study analyzed for the incidence of MZT of all clinical pregnancies after a single embryo transfer was carried out between 2014 and 2018. The effect of different assisted reproductive technology (ART) parameters on the incidence of MZT was evaluated.
There were a total of 8459 cycles resulting in pregnancy during the study period. Of these pregnancies, 8236 were singletons and 223 were MZT. The preterm birth rate, miscarriage rate, and cesarean section rate were higher in MZT. Birth weight and gestational age at delivery were lower and smaller. In the univariate analysis, the risk of MZT was decreased with frozen embryo transfer (ET). A nonlinear relationship was observed between maternal age and MZT. A negative relationship between maternal age and MZT was observed in the patients' age ≥ 36years.
Advanced maternal age was associated with a lower rate of MZT. A threshold female age of 36years existed for lower MZT.

To evaluated the metabolic profiles and vascular properties in congenital growth hormone (GH) deficiency (GHD) and its replacement in adults.
Cross-sectional study conducted in a single tertiary center for pituitary diseases. Eighty-one adult subjects were divided into three groups (1) 29 GHD patients with daily subcutaneous GH replacement therapy (GHRT) during adulthood; (2) 20 GHD patients without GHRT during adulthood and (3) 32 controls. Only patients with adequate adherence to others pituitary hormone deficiencies were included. Anthropometric parameters, body composition by dual-energy X-ray absorptiometry, metabolic profiles and vascular properties (carotid intima media thickness, pulse wave velocity and flow-mediated dilation) were compared among the groups.
Waist-to-height ratio (WHR), body fat percentages and fat mass index (FMI) were lower in patients with GHRT than patients without GHRT during adulthood (0.49 ± 0.06 vs. 0.53 ± 0.06 p = 0.026, 30 ± 10 vs. 40 ± 11 p = 0.003 and 7.3 ± 4 vs. 10 ring new insight into the treatment and follow-up of these patients.The study aimed to identify the mediating role of emotional intelligence and social competences in the relationship between gender and broad autism phenotype (BAP) as well as between age and BAP. It comprised 85 parents of children with ASD. They completed the questionnaires of Autism-Spectrum Quotient, social competences, and emotional intelligence. The results revealed that emotional intelligence in general and its two dimensions the ability to accept and express emotions and to empathize are important mediators of the relationship between gender and BAP. Also, social competences in general and two of their dimensions the effectiveness of behavior in intimate situations and in social situations were significant mediators. The relationship between age and BAP could not be confirmed.
Although several endoscopic findings of eosinophilic esophagitis (EoE), such as the EoE endoscopic reference score (EREFS), have been reported thus far, these endoscopic findings exhibit low specificity. Furthermore, most of these endoscopic findings were evaluated solely in patients from Western nations. We have recently noted a fragile, protruded mucosal lesion sandwiched between longitudinal furrows (similar to caterpillar tracks) on the esophagus in patients with EoE. We have termed this novel finding the "caterpillar sign". This study evaluated the clinical significance of the caterpillar sign and the EREFS for diagnosis of EoE in Japanese patients.
We retrospectively analyzed endoscopic images from 165 consecutive patients who underwent tissue collection on suspicion of EoE. We compared the clinical significance between the EREFS and the caterpillar sign. We defined EoE as the presence of ≥ 15 eosinophils on esophageal mucosa per high-power field; control images had < 15 eosinophils per high-powebe a novel reliable indicator for endoscopic diagnosis of EoE.
Neurofilament light chain (NfL) in serum indicates neuro-axonal damage in diseases of the central and peripheral nervous system. Reliable markers to enable early estimation of clinical outcome of intensive care unit (ICU) patients are lacking. The aim of this study was to investigate, whether serum NfL levels are a possible biomarker for prediction of outcome of ICU patients.
Thirty five patients were prospectively examined from admission to ICU until discharge from the hospital or death. NfL levels were measured longitudinally by a Simoa assay.
NfL was elevated in all ICU patients and reached its maximum at day 35 of ICU treatment. Outcome determined by modified Rankin Scale at the end of the follow-up period correlated with NfL level at admission, especially in the group of patients with impairment of the central nervous system (n = 25, r = 0.56, p = 0.02).
NfL could be used as a prognostic marker for outcome of ICU patients, especially in patients with impairment of the central nervous system.

Neurolymphomatosis (NL) is a disease characterized by the infiltration of malignant lymphocytes into the peripheral nervous system. We report clinical features, radiographic findings, modes of treatment, and outcomes of patients with NL.
We retrospectively investigated patients with NL. We extracted data, including clinical features, magnetic resolution imaging (MRI),
F-fludeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) scans, cerebrospinal fluid cytology findings, the results of electrodiagnostic studies, as well as patient treatments and outcomes.
Ten NL patients were identified. All patients reported pain/paresthesia and weakness in the affected area. The MRI scans were abnormal in eight out of nine patients with an enhancement of the spinal nerve root, plexus, peripheral nerve trunk, and cranial nerve. The FDG PET/CT scans were positive in all patients. Radiculopathy or radiculoplexopathy was the most common electrodiagnostic finding. Neurological improvement was obsern of NL are key. FDG PET/CT was the most sensitive diagnostic imaging modality to detect relevant neural invasion. The root within the spinal neural foramen was the most frequently affected neural structure. Early diagnosis of this rare neurologic manifestation of lymphoma may improve treatment outcomes.
Trait anxiety is associated with an increased occurrence of awake bruxism episodes, a behavior characterized by clenching of the teeth contributing to temporomandibular disorders in some individuals. Here we measured the activity of the masseter and the intensity and duration of spontaneous wake-time tooth clenching episodes in healthy individuals with different levels of trait anxiety (TA).
Two hundred fifty-five individuals completed a web survey. Using their TA scores, we allocated them in low (< 20
percentile of the TA score distribution), intermediate (between 20
and 80
), and high (> 80
) TA groups. We analyzed the electromyographic (EMG) activity of the right masseter during a 15-min silent reading task in forty-three individuals with low (n = 12), intermediate (n = 17), and high TA (n = 14). We tested between-group differences in EMG activity of the masseter, as well as postural activity-the muscular activity that maintains mandibular posture, and amplitude and duration of spontaneous tooth clenching episodes.
The activity of the masseter (mean ± SEM %maximum voluntary contraction/MVC) was greater in the high TA (10.23 ± 0.16%MVC) than the intermediate (8.49 ± 0.16%MVC) and low (7.97 ± 0.22%MVC) TA groups (all p < 0.001). Postural activity did not differ between groups (all p > 0.05). The EMGamplitude of tooth clenching episodes was greater in the high TA (19.97 ± 0.21 %MVC) than the intermediate (16.40 ± 0.24%MVC) and low (15.48 ± 0.38 %MVC) TA groups (all p < 0.05). The cumulative duration of clenching episodes was not different between groups (p = 0.390).
Increased TA is associated with both increased masseter muscle activity and intensity of wake-time tooth clenching episodes.
TA may contribute significantly to masticatory muscle overload.
