Patients with asthma are comparatively susceptible to respiratory viral infections and more likely to develop severe symptoms than people without asthma. During the coronavirus disease 2019 (COVID-19) pandemic, it is necessary to adequately evaluate the characteristics and outcomes of the population with asthma in the population tested for and diagnosed as having COVID-19.

To perform a study to assess the impact of asthma on COVID-19 diagnosis, presenting symptoms, disease severity, and cytokine profiles.

This was an analysis of a prospectively collected cohort of patients suspected of having COVID-19 who presented for COVID-19 testing at a tertiary medical center in Missouri between March 2020 and September 2020. We classified and analyzed patients according to their pre-existing asthma diagnosis and subsequent COVID-19 testing results.

Patients suspected of having COVID-19 (N= 435) were enrolled in this study. The proportions of patients testing positive for COVID-19 were 69.2% and 81.9% in the groue risk of COVID-19 severity if infected.

It is suggested that maternal mental health during pregnancy may affect offspring immune and respiratory features, based on the developmental origins of health and disease hypothesis.

To evaluate whether maternal quality of life (QoL) and depression during pregnancy leads to wheezing, asthma, and food allergy of the offspring at 3 years of age.

We conducted a nationwide, multicenter, prospective birth cohort study, Japan Environment and Children's Study. All variables were collected from questionnaires. Health-related QoL was measured using the Medical Outcomes Survey Short Form-8 questionnaire with a physical component summary and a mental component summary score. We conducted logistic regression analyses to evaluate the associations of offspring's wheezing, asthma, and food allergy with maternal QoL and depression.

There were 72,685 participants with no missing variables. Maternal physical component summary scores of the Medical Outcomes Survey Short Form-8 questionnaire were negatively associated with offspring's asthma (adjusted odds ratio [aOR], 0.99; 95% confidence interval [CI], 0.99-1.00), current wheezing (aOR, 0.99; 95% CI, 0.99-0.99), and food allergy diagnoses (aOR, 0.99; 95% CI, 0.98-0.99) in children. Offspring's wheezing and asthma were also associated with maternal depression and anxiety during pregnancy.

Poor maternal prenatal QoL increased the risk of wheezing, asthma, and food allergy in offspring. In addition, maternal depression and anxiety increased the risk of offspring's wheezing, asthma, and food allergy.

Metal allergy may be an uncommon cause of prosthetic joint failure. There exist little data on patch testing to metals in this context and its impact on outcomes of joint revision in these patients.

To explore the use and indications for metal patch testing in the evaluation of patients suspected of having metal allergy as a cause of failed joint replacements and to clarify the outcomes of patients revised with alternative metallic joints because of positive patch testing result.

A retrospective analysis from January 2016 to April 2020 was completed on a patient cohort referred for evaluation of metal hypersensitivity. Charts were reviewed for age, biological sex, referring specialty, patch testing results, joint, revision status, and outcome measures. Biostatistical analysis and descriptive statistics were performed to determine patch testing performance and functional outcome trends among this patient cohort.

The sensitivity and specificity of patch testing, in general, are limited when evaluating pith history of metal sensitivity and prosthetic failure.

Molecular information derived from dynamic [

F]sodium fluoride ([

F]NaF) PET imaging holds promise as a quantitative marker of bone metabolism. The objective of this work was to evaluate physiological mechanisms of [

F]NaF uptake in subchondral bone of individuals with and without knee osteoarthritis (OA).

Eleven healthy volunteers and twenty OA subjects were included. selleck products Both knees of all subjects were scanned simultaneously using a 3T hybrid PET/MRI system. MRI MOAKS assessment was performed to score the presence and size of osteophytes, bone marrow lesions, and cartilage lesions. Subchondral bone kinetic parameters of bone perfusion (K

), tracer extraction fraction, and total tracer uptake into bone (K

) were evaluated using the Hawkins 3-compartment model. Measures were compared between structurally normal-appearing bone regions and those with structural findings.

Mean and maximum SUV and kinetic parameters K

, K

, and extraction fraction were significantly different between Healthy subjects andPET imaging can complement assessments of structural abnormalities observed on MRI.

C-UCB-J binds to synaptic vesicle glycoprotein 2A, a protein ubiquitously expressed in presynaptic nerve terminals, and can therefore serve as in vivo proxy of synaptic density. There are discrepancies in postmortem data on stability of synaptic density with healthy aging. In this study, healthy aging and sex as potential modifiers of

C-UCB-J binding were investigated in healthy volunteers over 7 adult decades, assuming that the number of SV2A vesicles per synapse is not influenced by age or sex.

80 healthy volunteers underwent

C-UCB-J PET and structural T1 and T2 MR imaging. Grey matter changes with aging were firstly evaluated by voxel-based morphometry (VBM). Parametric

C-UCB-J standardized uptake value ratio (SUVR) images were calculated using the centrum semiovale as reference tissue. To correct for atrophy-related partial volume effects, a region-based voxel-wise type partial volume correction (PVC) was applied in FreeSurfer. The correlations of

C-UCB-J binding with age and with sex were inv1C-UCB-J does not support a cortical decrease of synaptic density with aging, whereas subcortically a small effect with aging in the caudate nucleus was observed. In addition, no association between synaptic density and sex was detected, which allows pooling of datasets of both sexes.
