Oral allergy syndrome (OAS) is an IgE-mediated food allergy. Ingestion of causative antigens leads to the development of local symptoms such as numbness of the oral mucosa in most cases and anaphylaxis in a few cases. The prevalence of OAS including in healthy people has not been investigated. Thus, we conducted a questionnaire survey of Japanese university students.

We conducted a cross-sectional study of 2688 first-year students using a questionnaire survey in marksheet format and examined the epidemiological characteristics of OAS.

Only 2.7% of students were aware of the term "oral allergy syndrome". A total of 143 (5.3%) students had OAS. There were significant associations between OAS and other allergic diseases including allergic rhinitis (AR) (OR 3.8, 95% CI 2.7-5.5), atopic dermatitis (AD) (OR 4.6, 95%CI 3.3-6.6), and bronchial asthma (BA) (OR 3.0, 95%CI 2.0-4.5). The onset age of OAS showed bimodal peaks at 0 and 10 years, and the latter peak coincided with the peak onset age of AR.

Awarenessnt OAS-related symptoms such as anaphylaxis.
Right ventricular (RV) contractile reserve shows promise as an indicator of occult RV dysfunction in pulmonary vascular disease. We investigated which measure of RV contractile reserve during exercise best predicts occult RV dysfunction and clinical outcomes.

We prospectively studied RV contractile reserve in 35 human subjects referred for right heart catheterization for known or suspected pulmonary hypertension. All underwent cardiac magnetic resonance imaging, echocardiography, and supine invasive cardiopulmonary exercise testing with concomitant RV pressure-volume catheterization. Event-free survival was prospectively adjudicated from time of right heart catheterization for a 4-year follow-up period.

RV contractile reserve during exercise, as measured by a positive change in end-systolic elastance (Ees) during exertion, was associated with elevation in pulmonary pressures but preservation of RV volumes. Lack of RV reserve, on the other hand, was tightly coupled with acute RV dilation during exertion (R
 = 0.76, p< 0.001). RV Ees and dilation changes each predicted resting RV-PA dysfunction. RV ejection fraction during exercise, which captured exertional changes in both RV Ees and RV dilation, proved to be a robust surrogate for RV contractile reserve. Reduced exercise RV ejection fraction best predicted occult RV dysfunction among a variety of resting and exercise RV measures, and was also associated with clinical worsening.

RV ejection fraction during exercise, as an index of RV contractile reserve, allows for excellent identification of occult RV dysfunction, more so than resting measures of RV function, and may predict clinical outcomes as well.

Long-term outcome in PAH is best preserved by targeting hemodynamic improvements to reduce risk of subsequent right ventricular (RV) failure. Saracatinib manufacturer Methods that can assess RV adaptation to stress have important implications to better understand an individual's physiology and may play a pivotal role in guiding therapy in PAH. In this novel pilot study, we evaluate the feasibility of monitoring hemodynamic response to 6-minute walk distance in patients with PAH using the CardioMEMS HF System.Leigh syndrome is a severe mitochondrial neurodegenerative disease with no effective treatment. In the Ndufs4-/- mouse model of Leigh syndrome, continuously breathing 11% O2 (hypoxia) prevents neurodegeneration and leads to a dramatic extension (~5-fold) in lifespan. We investigated the effect of hypoxia on the brain metabolism of Ndufs4-/- mice by studying blood gas tensions and metabolite levels in simultaneously sampled arterial and cerebral internal jugular venous (IJV) blood. Relatively healthy Ndufs4-/- and wildtype (WT) mice breathing air until postnatal age ~38 d were compared to Ndufs4-/- and WT mice breathing air until ~38 days old followed by 4-weeks of breathing 11% O2. Compared to WT control mice, Ndufs4-/- mice breathing air have reduced brain O2 consumption as evidenced by an elevated partial pressure of O2 in IJV blood (PijvO2) despite a normal PO2 in arterial blood, and higher lactate/pyruvate (L/P) ratios in IJV plasma revealed by metabolic profiling. In Ndufs4-/- mice, hypoxia treatment normalized the cerebral venous PijvO2 and L/P ratios, and decreased levels of nicotinate in IJV plasma. Brain concentrations of nicotinamide adenine dinucleotide (NAD+) were lower in Ndufs4-/- mice breathing air than in WT mice, but preserved at WT levels with hypoxia treatment. Although mild hypoxia (17% O2) has been shown to be an ineffective therapy for Ndufs4-/- mice, we find that when combined with nicotinic acid supplementation it provides a modest improvement in neurodegeneration and lifespan. Therapies targeting both brain hyperoxia and NAD+ deficiency may hold promise for treating Leigh syndrome.Fibroma of tendon sheath is a rare benign tumor originating in the tendon or tendon sheath. It most commonly occurs in upper extremity and rarely presents in the foot. In this report, a case of fibroma of tendon sheath in the web space with Morton's neuroma-like symptoms was presented. The tumor was resected endoscopically with preservation of the interdigital nerve. Post-operatively, the symptoms were subsided and the toe sensation was preserved. There was no sign of recurrence of the tumor at the end of 3-year-period of follow-up.
To determine whether personalized, stepped prehabilitation care is a feasible, safe, and effective implementation strategy.

Quality improvement project. Data collected prospectively from August 2018 to December 2019 were analyzed retrospectively to describe the clinical implementation of a prehabilitation care program for elective lung cancer surgery.

Single center, tertiary university hospital.

Eighty-one consecutive adult patients living in the metropolitan area of Montreal were included if an elective resection of suspected or confirmed lung cancer was planned.

At the earliest contemplation of surgery, the whole cohort was screened for impaired physical, nutritional, and/or psychological status. Patients screened at higher risk received dedicated assessmentand personalized prehabilitation care upon specific needs.

Patients' specific needs and their access and flow through the different services were described. Prehabilitation effectiveness was evaluated using walking and exercise tests, and advitation program targeting high-risk patients undergoing elective lung cancer surgery was feasible, safe, and effective.

To identify the causal relation between growth velocity and injury in elite-level youth football players, and to assess the mediating effects of motor performance in this causal pathway.

Prospective cohort study.

We measured the body height of 378 male elite-level football players of the U13 to U15 age categories three to four months before and at the start of the competitive season. At the start of the season, players also performed a motor performance test battery, including motor coordination (Körperkoordinationstest für Kinder), muscular performance (standing broad jump, counter movement jump), flexibility (sit and reach), and endurance measures (YoYo intermittent recovery test). Injuries were continuously registered by the academies' medical staff during the first two months of the season. Based on the causal directed acyclic graph (DAG) that identified our assumptions about causal relations between growth velocity (standardized to cm/y), injuries, and motor performance, the causal effect of growth velocity on injury was obtained by conditioning on maturity offset. We determined the natural indirect effects of growth velocity on injury mediated through motor performance.

In total, 105 players sustained an injury. Odds ratios (OR) showed a 15% increase in injury risk per centimetre/year of growth velocity (1.15, 95%CI 1.05-1.26). There was no causal effect of growth on injury through the motor performance mediated pathways (all ORs were close to 1.0 with narrow 95%CIs).

Growth velocity is causally related to injury risk in elite-level youth football players, but motor performance does not mediate this relation.

Here we review the advances in take-all research over the last 15 years, focusing on the identification of new sources of genetic resistance in wheat relatives and the role of the microbiome in disease development. We also highlight recent breakthroughs in the molecular interactions between G. tritici and wheat, including genome and transcriptome analyses. These new findings will aid the development of novel control strategies against take-all disease. In light of this growing understanding, the G. tritici-wheat interaction could provide a model study system for root-infecting fungal pathogens of cereals.
This study was undertaken to select an appropriate tool to predict risk of obstructive sleep apnea (OSA) among pediatric patients in the preoperative setting.

A retrospective chart review and a survey of nursing staff to compare two tools that were determined to be valid in assessing risk of OSA and postanesthesia complications in pediatric patients aged 6months to 18years was conducted. About 300 pediatric patients presenting for elective surgery were screened for OSA using STBUR (Snoring, Trouble Breathing during sleep, struggling to Breathe during Sleep, and waking UnRefreshed) and ST(1)OP-BANG (Snoring, Tonsillar hypertrophy, sleep Obstruction, BMI, Age, Neuromuscular disorders, and Genetic/congenital deformities) concurrently. Six preoperative nurses were then surveyed to compare ease of use and time to complete the screening tools.

The STBUR tool was found to predict complications in 37.5% patients versus 22.7% patients with the pediatric ST(1)OP-BANG. Nursing staff found that although both tools were quick and easy to use, the STBUR tool was easier for parents to answer.

Use of a screening tool to help predict risk of OSA and postanesthetic complications also helps to dictate anesthesia technique, nursing staffing requirements, and plans of care for postoperative management of pediatric patients.

Dementia, diabetes, and African American race are three factors that are independently associated with emergency department (ED) use. This study tested the hypothesis that ED use is associated with worse cognitive function in African Americans with Mild Cognitive Impairment (MCI) and poorly controlled diabetes.

This study examined differences in ED use among African Americans with MCI and diabetes in a secondary data analysis of baseline data from a one-year randomized controlled trial (N = 101).

Over one year, 49/92 participants (53.3%) had at least one ED visit. At baseline, participants who had an incident ED visit had significantly fewer years of education; lower scores on neuropsychological tests assessing working memory, psychomotor speed, and complex scanning; higher diabetes-related interpersonal distress scores; lower adherence to a diabetes medication; and higher hemoglobin A1c levels compared to participants with no ED visits (p ≤ 0.05 for all comparisons).

This study identified multiple risk factors for ED visits in older African Americans with MCI and diabetes.
