Schools should adopt a team- or whole-school approach to develop and enforce policies that help protect children with food allergies.
With so much variation in food allergy policies in schools coupled with inconsistent enforcement, parents and children may feel unsafe or unsupported by the school. Schools should adopt a team- or whole-school approach to develop and enforce policies that help protect children with food allergies.The purpose of this study is to maintain the proliferation capability of human parotid gland acinar cells (ACs) in vitro to extend passage number and to study the mechanism that regulates AC stemness. N-acetylglucosaminyltransferase V (GnT-V) is the Golgi enzyme, and it has been reported that the β1,6GlcNAc-branched N-linked glycans are associated with various cell behaviors. Therefore, we modify the gene expression of ACs by transfection of the GnT-V-overexpression plasmid, and we found that upregulation of GnT-V extensively increased ACs proliferation and stemness properties in ACs/GnT-V compared to ACs transfected with Mock plasmid. More importantly, we observed that high levels of GnT-V positively correlated with ALDH1A3 expression via increasing phosphorylation of cell surface receptors and activating the downstream signaling transduction. Hence, the current study suggested that GnT-V is a significant factor for cell immortalization in the ACs model by activating the EGFR/ERK/ALDH1A3 signaling pathway.Biomarkers of neuronal damage in status epilepticus (SE) would be of great relevance for clinical and research purposes. In a retrospective cross-sectional study, serum neurofilament light chain (NfL) levels were measured in patients with SE (30 subjects), patients with drug-resistant epilepsy (30 subjects), and healthy controls (30 subjects). Serum NfL levels were higher in patients with SE (median = 26.15 pg/ml) compared to both epilepsy patients (median = 7.35 pg/ml) and healthy controls (median = 6.81 pg/ml; p 28.8 pg/ml predicted 30-day clinical worsening or death (odds ratio [OR] = 10.83, 95% confidence interval [CI] = 1.96-59.83, p = .006) and SE refractoriness (OR = 9.33, 95% CI = 1.51-57.65, p = .016). In conclusion, serum NfL levels are increased in SE and correlate with SE treatment response, duration, and outcomes, therefore representing a promising biomarker of seizure-related neuronal damage.
To examine nonprofit hospitals' financial and spending allocations when the private sector payment rate is higher than the Medicare's payment rate.

Hospital financial data for 2014-2018 from Center for Medicare and Medicaid Services Hospital Cost Reports, hospital characteristics from the American Hospital Association (AHA) Annual Survey.

Hospital and year level fixed effects regressions modeling each hospital's (1) operating net income per discharge equivalent (DE); (2) administrative cost per DE; (3) patient care cost per DE; (4) registered nurse per bed; charity care cost per DE; and (5) provision of unprofitable services as a function of the private sector to Medicare payment ratio (PMR).

Hospital/year-level data from hospital cost reports merged with AHA data. check details Samples included general short-term hospitals with nonprofit ownership, excluding critical access hospitals.

The final sample included a total of 8862 hospital-year observations, with a mean PMR of 1.62. Nonprofit hospitals having a 0.1 higher PMR were associated with $257 (95% CI $181-$334) increase in operating net income per DE; $66 (95% CI $32-$99) increase in administrative cost per DE; $170 (95% CI $120-$220) increase in patient care cost per DE; and $18 (95% CI $10-$25) increase in charity care cost per DE. We found hospitals hired 0.86 (95% CI -0.08 to 1.81) more registered nurses per 100 beds, but no evidence on providing more beds for unprofitable services, such as obstetric care, burn care, alcohol/drug abuse treatment, or psychiatric care.

Higher private sector prices led primarily to greater surplus and administrative cost for nonprofit hospitals and smaller increases in spending on services that will directly benefit patients.

People report negative attitudes towards fractions and percentages relative to whole numbers (WNs, Sidney, Thompson, Fitzsimmons, & Taber, 2021), and these attitudes may relate to an individual's interpretation of what experiences with these number types signify. Because fractions are challenging, individual differences related to beliefs about challenge, such as endorsement of a growth versus fixed mindset (Dweck, 2006) and interpretations of easy or difficult experiences (Fisher & Oyserman, 2017), could relate to attitudes towards fractions relative to other number types.

Two studies tested whether gender, math skills, mindset beliefs, and perceptions of difficulty relate to negative math attitudes towards specific number types.

Two samples of college students (Study 1 N = 491; Study 2 N = 415), approximately 19 years of age (17% male, 51% first year students) participated.

Participants rated attitudes pertaining to WNs, fractions, and percentages, endorsement of a growth mindset, and perceptions of ease and difficulty.

Replicating prior work (Sidney, Thompson, Fitzsimmons, & Taber, 2021), college students endorsed more negative attitudes about fractions than WNs and percentages. Self-reported ACT scores related to all number-type attitudes, endorsement of the belief that 'difficult tasks/goals are important' related to fraction attitudes, andendorsement of the belief that 'easy tasks/goals are possible' related to whole number attitudes. Endorsement of a growth mindset did not relate to specific math attitudes.

People struggle to integrate their whole number and rational number representations, and one reason people hold negative attitudes about fractions may be that they view them as difficult and even impossible.

Examine whether Medicare Advantage (MA) coverage is associated with more efficient prescribing of Part B drugs than traditional Medicare (TM) coverage.

Twenty percent sample of 2016 outpatient and carrier TM claims and MA encounter records and Master Beneficiary Summary File data.

We analyzed whether MA enrollees compared to TM enrollees more often received the low-cost Part B drug in four clinical scenarios where multiple similarly effective drugs exist (1) anti-VEGF agents to treat macular degeneration, (2) bone resorption inhibitors for osteoporosis, (3) bone resorption inhibitors for malignant neoplasms, and (4) intravenous iron for iron deficiency anemia. We then estimated differences in spending if TM prescribing aligned with MA prescribing. Finally, using linear probability models, we examined whether differences in MA and TM prescribing patterns were attributable to differences in the hospitals and clinician practices who treat MA and TM enrollees or differences in how these hospitals and clinice more likely than TM enrollees to receive low-cost Part B drugs in four clinical scenarios where multiple similarly or equally effective treatment options exist.
Brain tumours are the most common and fatal of all solid tumours for children and adolescents. The effects of the tumour and treatment (chemotherapy, radiation, and/or surgery) results in significant disruptions to childhood development and large amounts of missed schooling. Among other challenges for families, this produces obstacles for children and adolescents to achieve and maintain academic performance and experience positive schooling encounters.

We thus aimed to systematically identify and synthesize qualitative evidence on how families experience paediatric brain tumour from diagnosis and beyond with regards to their schooling and education to identify gaps in service delivery, research, and policy.

A protocol for this review was registered with PROSPERO (ID CRD42020177165). Searches were conducted in Medline, CINAHL, PsycInfo, Embase, and Web of Science, and yielded 22 eligible papers (representing 17 studies). Data were extracted into NVivo12 and analysed by qualitative description.

We formeructures across families, health care facilities, schools, and educational departments are essential to achieving this.
This study was done to determine the representation of minorities, women, and the elderly in National Cancer Institute (NCI) clinical trials.

This is an analysis in the NCI Clinical Data Update System. Patients were evaluated in breast, colorectal, lung, and prostate cancer trials from 2000 to 2019. Representation in a trial was determined by race/ethnicity, sex, and age. Secondarily, the change in trial participation by multivariable analysis by comparing years 2000 through 2004 to 2015 through 2019 was evaluated.

The cohort included 242,720 participants 197,320 Non-Hispanic White (81.3%), 21,190 Black (8.7%), 11,587 Hispanic (4.8%), and 6880 Asian/Pacific Islander (2.8%). Black and Hispanic patients were underrepresented for colorectal (odds ratio [OR], 0.58; 95% confidence interval [CI], 0.50-0.67; P < .001 and OR, 0.74; 95% CI, 0.64-0.87; P < .001, respectively), lung (OR, 0.83; 95% CI, 0.76-0.91; P < .001 and 0.66; 95% CI, 0.57-0.77; P < .001, respectively), and prostate cancer trials ( has increased. These findings indicate that minority participation has increased over time, but further efforts are needed.
To investigate the safety and efficacy of intranasal ketamine for the treatment of a single cluster headache (CH) attack.

Acute treatment options for patients with CH who have an insufficient response to oxygen and triptans are limited. Intranasal ketamine has anecdotally been successful in treating a CH attack.

We conducted an open-label pilot study enrolling 23 patients with chronic CH (International Classification of Headache Disorders, 3rd edition), and of these, 20 patients treated a single CH attack with intranasal ketamine. Under in-hospital observation, patients received 15mg of intranasal ketamine every 6min a maximum of five times. The primary endpoint was a 50% reduction in pain intensity within 15min after initiating treatment.

The primary endpoint was not met; 15min after the first ketamine administration, the mean reduction in pain intensity was 1.1 (95% confidence interval [CI] -0.6 to 2.7, p=0.188) on the numeric rating scale (NRS), equivalent to a 15% reduction in pain intensity. However, 30min after the first application, the pain intensity was reduced by 59% on an 11-point NRS (mean difference 4.3, 95% CI 2.4-6.2, p<0.001, N=16) and 11 out of 16 (69%) scored 4 or below on the NRS. Four patients received rescue medication 15min after the first ketamine application and were therefore excluded from the analysis at 30min. Half of the patients preferred ketamine to oxygen and/or sumatriptan injection. No serious adverse events were identified during the trial.

Intranasal ketamine may be an effective acute treatment for CH at 30min but should be tested in a larger controlled design. Patients and physicians should be conscious of the abuse potential of ketamine.
