03), while cerebral autoregulation was not affected and showed no difference. Conclusion Cerebral hemodynamics in mild neonatal encephalopathy is heterogeneous across different brain regions, while cerebral autoregulation remains intact. These findings indicate the robustness of the wavelet measure of cerebral autoregulation in this population, but need to be further investigated in the presence of severe injury. Impact This proof-of-concept study is the first to investigate the regional difference of cerebral hemodynamics and autoregulation in mild neonatal encephalopathy.Study findings confirm that brain functions are complex in the developing neonatal brain and that cerebral hemodynamics are region specific in newborns with frontal-posterior heterogeneity among brain regions probed by multichannel NIRS.Regional MRI lesions were associated with differences across NIRS regional channels among the affected side.Cerebral autoregulation with multichannel NIRS is not affected by regional MRI abnormalities.Background Very low birth weight (VLBW) infants may be at risk for late-onset circulatory collapse (LCC) where otherwise stable infants develop hypotension resistant to vasoactive agents. The risk factors for LCC development are poorly defined, and it has been theorized that it may be in part due to withdrawal from exogenous prenatal steroids. The goal of this study was to define the clinical characteristics of LCC and investigate its association with antenatal steroid administration. Methods This is a retrospective cohort study of infants born ≤1500 g. Human cathelicidin ic50 LCC was retrospectively diagnosed in infants requiring glucocorticoids for circulatory instability at >1 week of life. Demographic and clinical characteristics were compared between groups using Mann-Whitney test. Results Three hundred and ten infants were included; 19 (6.1%) developed LCC. Infants with LCC were born at a median 4.6 weeks' lower gestation, 509 g lower birth weight than those without LCC. There was no difference in antenatal steroid delivery bef LCC in a U.S.-based cohort will provide insight into both its prevalence and presentation to inform clinicians about this potentially devastating disorder and foster early diagnosis and treatment.This study validates LCC characteristics and prevalence previously outlined by Asian studies in a single-center U.S.-based cohort while also identifying potential risk factors for LCC development.This manuscript will provide education for U.S. physicians about the risk factors and clinical presentation of LCC to facilitate early diagnosis and treatment, potentially decreasing neonatal mortality.With prompt recognition and treatment of LCC, infants may have decreased exposure to vasoactive medications that have significant systemic effects.Background Psychosocial stress in early childhood is associated with adult obesity and cardiometabolic disease. The association of psychosocial stress with the metabolome in childhood is unknown. Method Low-income children (n = 28, mean age 1.8 years), recruited from the community, participated. Psychosocial stress was measured by diurnal salivary cortisol (cortisol intercept and slope) and by mother-reported chaos in the home using the Confusion, Hubbub, and Order Scale (CHAOS). At mean age 6.1 years, anthropometry was collected and fasting metabolites measured using an untargeted metabolomics and shotgun lipidomics platform. Results Cortisol slope was inversely associated with fatty acid (FA) 203, FA 204 and polyunsaturated fatty acids (PUFA) metabolites. A higher CHAOS score was associated with lower very long-chain PUFA metabolites and a trend towards lower long-chain PUFA containing triglycerides. Conclusions Psychosocial stress in early childhood, measured with both biological markers and parent report, was associated with lower PUFAs later in childhood. Future work should examine potential mechanisms of association, including dietary intake or direct effects on polyunsaturated fatty acid levels or metabolism. Impact In this longitudinal study, the key message is that diurnal cortisol patterns and greater parent-reported psychosocial stress exposure in early childhood are associated with lower plasma polyunsaturated fatty acid containing lipids 5 years later, potentially indicating altered dietary intake or metabolism associated with psychosocial stress. Untargeted metabolomics and lipidomics can be used to assess changes in metabolism response to psychosocial stress. Stress exposure in early childhood may be associated with the future metabolome. Future work should examine potential pathways of association, including dietary intake and direct effects on metabolism.Objectives To analyze the diagnostic accuracy of two-dimensional (2D) and three-dimensional transvaginal ultrasound (3D TV-US) for evaluation of parametrial status in locally advanced cervical cancer patients after neoadjuvant chemotherapy (NACT), using histology as the gold standard. Methods Consecutive patients with histologically confirmed cervical cancer were staged according to FIGO (International Federation of Gynaecology and Obstetrics) criteria. All IB2-IIIB FIGO stage patients were examined by 2D and 3D TV-US and magnetic resonance imaging (MRI) at the diagnosis time (T0) and after NACT. At T0, the US evaluation of parametrial involvement was compared to MRI before treatment. The results of US and MRI examinations of parametrial status after NACT were compared with the histological specimen. Results We enroled 51 consecutive patients in the study. Before chemotherapy, clinical examination under anaesthesia identified parametrial involvement in 48 patients, ultrasonography in 46 patients, and MRI in 48%, respectively. Conclusion In locally advanced cervical cancer patients, 2D/3D TV-US can be considered accurate in the evaluation of parametrial infiltration to assess the response to NACT. link2 It could be included as a diagnostic method in the preoperative work-up of cervical cancer.Introduction Football is characterised by intermittent high-intensity efforts varying according to the field position of a player. We wished to ascertain whether polymorphisms in the ACTN3 gene are associated to different playing positions in elite professional football players. Subjects and methods Genotyping of the ACTN3 gene was conducted in 43 elite professional football players of a single team. Playing position was recorded based on the player's most frequent position. Results The genotype distribution was not significant between positions (p=0.057), while the allele distribution differed significantly (p=0.035). Goalkeepers (p=0.04, p=0.03), central defenders (p=0.03, p=0.01) and central midfielders (p=0.01, p=0.00) had a significantly different allele distribution compared with wide midfielders and forward players. Conclusions Genetic biomarkers may be important when analysing performance capability in elite professional football. Identifying the genetic characteristics of a player to adapt his playing position may lead to a position orientation based on physical capabilities and tissue quality in young football players and to performance enhancement in those who are already playing in professional teams.Introduction One of the most frequent abnormalities of B cells in common variable immunodeficiency (CVID) is reduced number of class-switched memory B cells, suggesting an impaired germinal center response. Therefore, due to its pivotal role in regulating the development of humoral immunity, the objective of this study was to evaluate the role of circulating T follicular helper (cTFH) and circulating T follicular regulatory (cTFR) cells in the pathogenesis of CVID. Methods cTFH and cTFR cells from CVID patients and healthy subjects were phenotypically characterized by flow cytometry. cTFH and memory B cells from CVID patients and healthy subjects were isolated and cocultured. Results Our results showed a reduced proportion of cTFH17 cells in patients with CVID and an increased ratio of cTFH/cTFR cells in CVID patients with autoimmune diseases. Furthermore, the proportion of IL-21-producing cTFH cells was directly related to the proportion of CD27+ IgD- B cells. Interestingly, coculture assay showed that CVID-derived cTFH cells are able to help memory B cells from healthy controls to produce immunoglobulins. Conclusions The proportions of cTFH17 and cTFR cells are altered in CVID patients; however, the cTFH function in assisting B cells to produce antibodies in vitro is preserved.Background Wake-up stroke (WUS) accounts for up to 25% of all new ischemic strokes, but debate exists regarding whether WUS differs from non-WUS in previous studies. Our study aimed to investigate the proportion of WUS cases and to examine differences in clinical characteristics and outcomes in these two groups. Methods Data from acute ischemic stroke patients who presented to the First Affiliated Hospital of Chongqing Medical University between April 2017 and September 2017 were prospectively collected. Admission demographic information, clinical and radiological characteristics, and 3-month functional outcomes were assessed and compared between patients with WUS and those with non-WUS. Poor functional outcome was defined as modified Rankin Scale ≥ 3 at the 90-day follow-up. Risks of poor outcomes for WUS were estimated with logistic regression analysis. Results A total of 473 eligible patients were included, of which 132 had been diagnosed with WUS (27.9%). Forty WUS patients had poor functional outcomes an WUS accounts for 27.9% of 473 ischemic strokes in the Chinese population. WUS and non-WUS patients were similar in terms of stroke risk factors, severity, etiology, and early outcomes. Age, previous stroke, and a high admission NIHSS score were independent risk factors for unfavorable outcomes in patients with WUS.Introduction Many clinical trials fail because of placebo responses. Prior therapeutic experiences and patients' expectations may affect the capacity to respond to placebos in chronic disorders. Objective The scope of this study in 763 chronic orofacial pain and healthy study participants was to compare the magnitude and prevalence of placebo effects and determine the putative role of prior therapeutic experiences vs. expectations. link3 Methods We tested placebo propensity in a laboratory setting by using 2 distinct levels of individually tailored painful stimulations (high pain and low pain) to reinforce expectations and provide a hypoalgesic experience (conditioning phase). Afterwards, both levels of pain were surreptitiously set at a moderate pain level to test for placebo effects (testing phase). Pain and expectation ratings were assessed as primary outcomes using visual analog scales. Results In both chronic pain and healthy participants, placebo effects were similar in magnitude, with the larger prevalence of responders in the healthy participants. Although chronic pain participants reported higher pain relief expectations, expectations did not account for the occurrence of placebo effects. Rather, prior experience via conditioning strength mediated placebo effects in both pain and healthy participants. Conclusions These findings indicate that participants with chronic pain conditions display robust placebo effects that are not mediated by expectations but are instead directly linked to prior therapeutic experiences. This confirms the importance of assessing the therapeutic history while raising questions about the utility of expectation ratings. Future research is needed to enhance prediction of responses to placebos, which will ultimately improve clinical trial designs.
