OBJECTIVE: The objective of this study was to determine serum fibroblast growth factor-23 levels in preeclampsia, eclampsia, gestational hypertension, and the presence of fetal growth restriction subgroups.
METHODS: A total of 55 pregnant women with planned cesarean section were included in this cross-sectional study. They were divided into two groups, namely, control (25) and gestational hypertensive disease (30). The gestational hypertensive disease group was evaluated by dividing it into three subgroups (preeclampsia, eclampsia, and gestational hypertension) according to the clinical and laboratory findings of the disease and two subgroups (presence of fetal growth restriction and absence of fetal growth restriction) according to the birth weight percentile. Demographic parameters, obstetric history, physical examination findings, and laboratory values were evaluated.
RESULTS: Demographic parameters and obstetric history were similar between the two groups, while gestational week of delivery was lower in the gestational hypertensive disease group (p=0.002). Laboratory parameters and serum fibroblast growth factor-23 (pg/mL) values were similar between the two groups. In the subgroup analysis for gestational hypertension, preeclampsia, and eclampsia, there was no statistically significant difference in serum fibroblast growth factor-23 levels between gestational hypertension, preeclampsia, eclampsia, and control groups. In the subgroup analysis based on the presence of fetal growth restriction, serum fibroblast growth factor-23 levels were similar to the control group in the gestational hypertensive disease absence of fetal growth restriction, while serum fibroblast growth factor-23 levels and serum calcium levels were statistically significantly lower in the gestational hypertensive disease with the presence of fetal growth restriction (p=0.044 and p<0.001, respectively).
CONCLUSION: Serum fibroblast growth factor-23 levels are similar between pregnancies complicated with gestational hypertensive disease and normotensive pregnancies. However, serum fibroblast growth factor-23 levels were found to be lower in pregnancies complicated with gestational hypertensive disease with the presence of fetal growth restriction.

BACKGROUND: Cervical cancer poses a heavy health burden in China, with the second highest incidence and mortality rate among female tumors, yet human papillomavirus (HPV) vaccination rate among female university students remain remains low. This study conducted a cross-sectional survey to assess the degree of HPV vaccine hesitancy among female university students and to explore the potential association between knowledge, risk perception, trust, and HPV vaccine hesitancy.
METHODS: A total of 1,438 female university students from four Chinese cities were recruited through stratified, multistage, cluster sampling method. The mediation model was constructed using the Bootstrap method, introducing trust and risk perception as mediating variables to examine the effect of knowledge on HPV vaccine hesitancy.
RESULTS: The study found that 8.9% (95%CI:7.4%∼10.4%) of the female university students exhibited HPV vaccine hesitancy. Pearson's correlation analysis revealed a negative association between vaccine hesitancy and knowledge, risk perception, and trust. The mediation model showed that knowledge had significant indirect effects on HPV vaccine hesitancy through trust (indirect effect: -0.224, 95% CI: -0.293 ∼ -0.167) and risk perception (indirect effect: -0.013, 95% CI: -0.033 ∼ -0.002).
CONCLUSION: HPV vaccine hesitancy among female university students has mitigated, but still needs to be addressed. In addition, trust and risk perception are mediators mediating the relationship between knowledge with HPV vaccine hesitancy. Therefore, there is a need to strengthen public health education to improve knowledge, with a particular focus on providing information about trust and risk perception to reduce HPV vaccine hesitancy.
BACKGROUND: Osteonecrosis is a complication of talar neck fractures associated with chronic pain and poor functional outcomes. The Hawkins sign, the radiographic presence of subchondral lucency seen in the talar dome 6 to 8 weeks after trauma, is a strong predictor of preserved talar vascularity. This study sought to assess the accuracy of the Hawkins sign in a contemporary cohort and assess factors associated with inaccuracy.
METHODS: A retrospective review of talar neck fractures at a level-I trauma center from 2008 to 2016 was conducted. Both the Hawkins sign and osteonecrosis were evaluated on radiographs. The Hawkins sign was determined on the basis of radiographs taken approximately 6 to 8 weeks after injury, whereas osteonecrosis was determined based on radiographs taken throughout follow-up. The Hawkins sign accuracy was assessed using proportions with 95% confidence intervals (CIs), and associations were examined with Fisher exact testing.
RESULTS: In total, 105 talar neck fractures were identified. The Hawkins sign was observed in 21 tali, 3 (14% [95% CI, 3% to 36%]) of which later developed osteonecrosis. In the remaining 84 tali without a Hawkins sign, 32 (38% [95% CI, 28% to 49%]) developed osteonecrosis. Of the 3 tali that developed osteonecrosis following observation of the Hawkins sign, all were in patients who smoked.
CONCLUSIONS: A positive Hawkins sign may not be a reliable predictor of preserved talar vascularity in all patients. We identified 3 patients with a positive Hawkins sign who developed osteonecrosis, all of whom were smokers. Factors impairing the restoration of microvascular blood supply to the talus may lead to osteonecrosis despite the presence of preserved macrovascular blood flow and an observed Hawkins sign. Further research is needed to understand the factors limiting Hawkins sign accuracy.
LEVEL OF EVIDENCE: Prognostic Level III . See Instructions for Authors for a complete description of levels of evidence.
BACKGROUND & AIMS: The changes in HBV-specific B cells in patients with chronic hepatitis B (CHB) undergoing pegylated interferon-α (PEG-IFNα) treatment and achieving functional cure remain unclear. We aimed to evaluate the alterations in HBV-specific B cells during treatment and therefore explored the mechanism of functional recovery of HBsAg-specific B cells.
METHODS: We included 39 nucleos(t)ide analogue-treated patients with CHB who received sequential combination therapy with PEG-IFNα and eight treatment-naïve patients. HBV-specific B cells were characterized ex vivo using fluorescently labeled hepatitis B surface and core antigens (HBsAg and HBcAg). The frequency, phenotype, and subsets of HBV-specific B cells and follicular helper T cells (Tfh cells) were detected using flow cytometry. The functionality of HBV-specific B cells was quantified through ELISpot assays.
RESULTS: During treatment, the fraction of activated memory B cells (MBCs) among HBsAg-specific B cells and the expression of IgG, CXCR3, and CD38 increased. The antibody-secretion capacity of HBsAg-specific B cells was only restored in patients achieving a functional cure after treatment and it positively correlated with serum hepatitis B surface antibody levels. The phenotype and function of HBsAg-specific B cells differed between patients with and without functional cure. Patients with functional cure exhibited IgG+ classical MBCs and plasmablasts among HBsAg-specific B cells. HBcAg-specific B cells displayed both attenuated antibody secretion with reduced IgG expression and an IgM+ atypical type of MBC after treatment, irrespective of functional cure. The number of CD40L+ Tfh cells increased after PEG-IFNα treatment and positively correlated with HBsAg-specific B-cell activation.
CONCLUSIONS: After PEG-IFNα treatment, HBsAg- and HBcAg-specific B cells exhibit various changes in antibody secretion. Their functional differences are reflected in the alterations in phenotypes and subtypes. The presence of CD40L+ Tfh cells is associated with the active recovery of HBsAg-specific B cells.
IMPACT AND IMPLICATIONS: HBV-related complications and hepatocellular carcinoma remain the leading causes of mortality from chronic liver disease worldwide, and a cure is rarely achieved with antiviral therapies. Elucidating the immunological mechanisms underlying the functional cure of patients with chronic hepatitis B offers a promising therapeutic strategy for viral clearance, e.g. via therapeutic vaccination. We analyzed the alterations in HBV-specific B cells in patients treated with pegylated interferon-α and identified novel pathways for immunotherapeutic boosting of B cell immunity.
This study is designed as a pragmatic trial. All candidates for endovascular treatment of one or more unruptured intracranial aneurysms will be offered to participate. Unruptured aneurysms may be recently discovered or prevalent. If they accept, subjects will be randomized to one of the two arms of the trial: Conservative management (Observation) or Endovascular treatment.

Both groups will be advised to obtain medical treatment for hypertension if necessary and will receive counselling for behavioural risk factor modelling (smoking or excessive drinking) when indicated. A non-invasive (MRA or CTA) or catheter angiogram and a baseline CT-scan or MRI of the brain are required to enter the study. These studies should demonstrate the unequivocal presence of a saccular aneurysm \>=3 mm treatable by endovascular methods. A catheter angiogram is required if there is doubt. Imaging studies will be reviewed centrally. Both treatments will be standardized. Patients will be followed similarly for a minimum of 10 years.

Chronic kidney disease (CKD) mineral and bone disorder (MBD) comprises a triad of biochemical abnormalities (of calcium, phosphate, parathyroid hormone and vitamin D), bone abnormalities (turnover, mineralization and growth) and extra-skeletal calcification. Mineral dysregulation leads to bone demineralization causing bone pain and an increased fracture risk compared to healthy peers. Vascular calcification, with hydroxyapatite deposition in the vessel wall, is a part of the CKD-MBD spectrum and, in turn, leads to vascular stiffness, left ventricular hypertrophy and a very high cardiovascular mortality risk. While the growing bone requires calcium, excess calcium can deposit in the vessels, such that the intake of calcium, calcium- containing medications and high calcium dialysate need to be carefully regulated. Normal physiological bone mineralization continues into the third decade of life, many years beyond the rapid growth in childhood and adolescence, implying that skeletal calcium requirements are much higher in younger people compared to the elderly. Much of the research into the link between bone (de)mineralization and vascular calcification in CKD has been performed in older adults and these data must not be extrapolated to children or younger adults. In this article, we explore the physiological changes in bone turnover and mineralization in children and young adults, the pathophysiology of mineral bone disease in CKD and a potential link between bone demineralization and vascular calcification.
This invention provides a non-radioactive assay to monitor and quantify the target-cell killing activities mediated by cytotoxic T lymphocytes (CTLs). This assay is predicated on the discovery that apoptosis pathway activation and, in particular, granzyme B activity, provides a measure of cytotoxic effector cell activity. In one embodiment, measurement of CTL-induced granzyme B activation in target cells is achieved through detection of the specific cleavage of fluorogenic granzyme B substrates. This assay reliably detects antigen-specific CTL killing of target cells, and provides a more sensitive, more informative and safer alternative to the standard  51 Cr-release assay most often used to quantify CTL responses. The assay can be used to study CTL-mediated killing of primary host target cells of different cell lineages, and enables the study of antigen-specific cellular immune responses in real time at the single-cell level. As such, the assay can provide a valuable tool for studies of infectious disease pathogenesis and development of new vaccines and immunotherapies.
A randomized controlled trial (RCT) involving nursing students from a university in Stockholm, Sweden. The students are randomly allocated in a 1:1 ratio to either VR (intervention) or standard training in triaging during a mass casualty Incident. Both groups of participants will receive the same lecture on disaster events and triage using the same method before undergoing triage training either with VR support or traditional paper-based training. To achieve a power of 0.80 and a p-value of 0.05, a total of 60 participants are required (control n=30, intervention n=30). However, all students (approximately 100) will be invited to participate in the study to avoid excluding those who wish to take part in the study. The primary outcome measure is the students' ability to triage correctly. Secondary outcome measures include knowledge and knowledge retention, as well as the time taken to triage correctly. Knowledge tests will be conducted approximately one week after training and again 3-6 months after completing the training. The knowledge test consists of a questionnaire with 20 multiple-choice questions used in previous studies.
The patient was a 49-year-old man presenting with recurrent melena due to progressive ulcerative colitis. One day, he developed left lower facial weakness and dysarthria, and the next day, he was transferred to our hospital because of muscle weakness in his left upper and lower extremities. On admission, neurological findings revealed left hemiplegia, including left facial palsy, dysarthria, and left hemispatial neglect. Brain MRI with diffusion-weighted image showed a fresh infarction in the right anterior and middle cerebral artery territory. Contrast-enhanced CT showed thrombus in the ascending aorta in addition to occlusion of the right internal carotid artery, suggesting the diagnosis of cerebral infarction with an embolic source in the aortic lesion. The intra-aortic thrombus disappeared after 48th day of antithrombotic therapy. Laboratory findings revealed elevated blood viscosity, proteinase-3-anti-neutrophil cytoplasmic antibody (PR3-ANCA), and β2GP1-IgG antibodies, suggesting that the cause of the aortic thrombus may be due to elevated blood viscosity and autoantibodies, as well as highly active ulcerative colitis.
The students in the experimental group will be divided into 8 main groups of 7 students according to their academic grade point average. In these groups, each member will be responsible for one of the 7 sections of the article. Those who take the same section in the groups will unite to form expert groups and specialize by working on this section. Students will then return to their main groups and analyze an experimental article. From the groups presenting their reviews, a winner will be selected and a prize will be awarded.
Participants will also be given access to the mindfulness app (Insight Timer), and instructed to use it for 10 min daily for 30 days. Two days before the end of the 30 day intervention period, participants will be sent a link to a Google Form for the post-intervention survey and will be asked to complete the survey within the next 3 days. Two months after the conclusion of the 30 day intervention period (90 days after study began), participants will be sent a link to a Google Form for another post-intervention survey, and asked to complete it within 5 days.
The study will be conducted in 2 parts for subjects with advanced malignancies and either normal liver function, or advanced malignancies and moderate, or severe hepatic impairment. Subjects in Part 1 of the study will receive a single oral, 800 mg dose of tazemetostat on Day 1 and Day 15. In addition, the subjects will receive tazemetostat (oral 800 mg dose) tablets to be taken twice daily from Day 5 to Day 14. Blood samples for PK analysis will be obtained on Day 1 through Day 4 and again on Day 15 through Day 18. Part 1 ends on Day 18.

Subjects continuing treatment in Part 2 will receive tazemetostat (oral 800 mg dose) tablets to be taken twice daily in repeated 28-day cycles beginning on Day 19 until Investigator-assessed clinical progression per standard practice, or unacceptable toxicity, or until another discontinuation criterion is met. Subjects must have an end of study visit for safety assessment 30 days after the last dose of tazemetostat or prior to initiation of a subsequent anticancer therapy, whichever occurs first. Supplementary study conduct information not mandated to be present in this protocol is provided in the accompanying procedure manuals (i.e., laboratory, pharmacy, ECG manuals). Such manuals will provide the site personnel with administrative and detailed technical information that does not impact subject safety.
In response to the growing number of outbreaks of emerging infectious diseases, the US Administration for Strategic Preparedness and Response (ASPR) has embarked on a plan to improve and expand special pathogen patient care capabilities. To achieve this, ASPR is developing a coordinated network of Regional Emerging Special Pathogen Treatment Centers (RESPTCs) to serve as state-of-the-art facilities staffed by a highly trained workforce to care for and manage special pathogen patients across the lifespan. The RESPTC network represents the operational arm of a broader US National Special Pathogen System of care to prevent and prepare for the next infectious disease outbreak. RESPTCs are strategically located in every region across the country and form a network linking local and regional healthcare partners to enhance national preparedness through training in best practices for detection, isolation, and treatment of individuals suspected of or known to be infected with a special pathogen. This local, regional, and national network is also designed to lead a coordinated response that includes the dissemination of accurate and trustworthy information to responders and the public. The overarching goal of the RESPTCs is to serve as a valuable resource for clinical care, training, and material support to meet current and future major infectious diseases challenges. In this case study, 2 new RESPTCs, MedStar Washington Hospital Center and the University of North Carolina, describe their experiences related to designing a biocontainment unit, creating clinical teams, building staff resiliency, receiving mentoring from regional RESPTC partners, and developing opportunities for innovation.
Plasma levels of endocannabinoids (eCBs) are very dynamic and variable in different circumstances and pathologies. The aim of the study was to determine the levels of the main eCBs and N-acylethanolamines (NAEs) in COVID-19 patients during the acute and post-acute phase of SARS-CoV-2 infection. Samples collected before December 31, 2020 were used for the determination of circulating eCB levels by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The association between plasma eCB measurements and biochemical and hematological parameters, as well as serum IL-6 levels, was evaluated. Samples of 64 individuals were analysed, n = 18 healthy donors, n = 30 acute, and n = 16 post-acute patients. Plasma levels of 2-arachidonoylglycerol (2-AG), were significantly elevated in COVID-19 patients when compared to healthy individuals. Plasma N-palmitoylethanolamide (PEA) and N-arachidonoylethanolamide (AEA) levels were found to be decreased in post-acute patient samples. These results suggest that 2-AG plays an important role in the inflammatory cascade in COVID-19 disease; in addition, eCBs might be involved in the post-acute pathogenesis of COVID-19. This study provides evidence of altered levels of circulating eCBs as a consequence of SARS-CoV-2 infection.
