Identification of Breathing Pattern Disorder in Athletes With Exercise-Induced Laryngeal Obstruction: A Novel Assessment Tool.

Objective: To report the diagnostic utility of the novel, high-ventilatory task assessment tool called the Milstein Breathing Pattern Assessment Index (M-BPAI) for evaluation of Breathing Pattern Disorder (BPD) in athletes with and without breathing difficulty, and to evaluate the prevalence of BPD in athletes referred for Exercise Induced Laryngeal Obstruction (EILO). BPD is an abnormal respiratory biomechanical pattern caused from functional or structural factors. The presence of BPD in athletes with EILO is unknown.

The use of virtual visits for obesity pharmacotherapy in patients with overweight or obesity compared with in-person encounters.

Objective: This study aimed to demonstrate noninferiority using telehealth in treating obesity with phentermine in patients with BMI ≥ 27 kg/m with comorbidities or BMI ≥ 30 compared with the standard in-person approach over a 90-day period.

Methods: A 12-week, randomized, prospective, single-center, open label trial compared the use of virtual visits versus in-person visits for the treatment of obesity using phentermine. The primary end point was percentage mean change in body weight from baseline to 12 weeks.

Assessing physical activity is an opportunity to encourage lifestyle-based tactics for reducing cardiovascular risk. These handy tables serve as practical guides.

Effects of Wearing an N95 Respirator or Cloth Mask Among Adults at Peak Exercise: A Randomized Crossover Trial.

This randomized crossover trial examines the effects of wearing a cloth mask or N95 respirator vs no mask at peak exercise among healthy, active adults.

Gamer's Health Guide: Optimizing Performance, Recognizing Hazards, and Promoting Wellness in Esports.

Electronic sports (esports), or competitive video gaming, is a rapidly growing industry and phenomenon. While around 90% of American children play video games recreationally, the average professional esports athlete spends 5.5 to 10 h gaming daily.

Sandwich corrected standard errors in family-based genome-wide association studies.

Given the availability of genotype and phenotype data collected in family members, the question arises which estimator ensures the most optimal use of such data in genome-wide scans. Using simulations, we compared the Unweighted Least Squares (ULS) and Maximum Likelihood (ML) procedures. The former is implemented in Plink and uses a sandwich correction to correct the standard errors for model misspecification of ignoring the clustering.

Fatal hemorrhagic pneumonia concomitant with Chlamydia pneumoniae and parainfluenza virus 4 infection.

Context: Cases of fatal hemorrhagic pneumonia need to be investigated for highly contagious viral causes. While not all hemorrhagic pneumonias are caused by very contagious agents, the etiology must be correctly determined in order to administer appropriate patient care.

Objective: To determine whether chlamydia, paramyxovirus, or mycoplasma was the causative agent in a case of fatal hemorrhagic pneumonia, and to evaluate the possibility that this was the first case of hantavirus pulmonary syndrome in Illinois.

Fatal Chaetomium cerebritis in a bone marrow transplant patient.

The number of opportunistic infections in the central nervous system (CNS) has been steadily increasing because of a rising number of immunocompromised patients. A rare form of CNS infection can be caused by Chaetomium species, one of the largest genera of saprophytic ascomycetes. The CNS lesions in the present case were caused by Chaetomium atrobrunneum.

Production of cytokinin-like substances by mycorrhizal fungi of pine (Pinus sylvestris L.) in cultures with and without metabolites of actinomycetes.

Studies on the effect of post culture liquids of actinomycetes on cytokinin-like substances production by mycorrhizal fungi have revealed that actinomycete metabolites inhibited or stimulated the synthesis of these compounds. The results of chromatographic analyses suggest, that substances stimulating the soybean callus are likely to be: riboside 6 (gamma, gamma-dimethylallylamino) purine and riboside zeatin. Using gas chromatography it was confirmed that both substances are produced by Rhizopogon luteolus.

Effect of pH on production of cytokinin-like substances by bacteria isolated from soil, rhizosphere and mycorrhizosphere of pine (Pinus silvestris L.).

Cytokinin-like substances were produced in higher amounts by soil isolates than by those isolated from the rhizosphere and mycorrhizosphere. However more bacterial strains isolated from the rhizosphere and mycorrhizosphere were capable of synthesizing cytokinin-like compounds. A distinct effect of pH on the production of these substances was found.

The synthesis of cytokinin-like substances by coryneform bacteria isolated from the roots of pine seedlings (Pinus silvestris L.).

Seven of ten strains studied produced cytokinin-like substances, mainly in 7 day old cultures. The cytokinin-like substances were most often located on chromatograms at Rf values 0.8 to 0.

Synthesis of auxins by fungi isolated from the roots of pine seedings (Pinus silvestris L.) and from soil.

Synthesis of auxins by fungi grown with and without tryptophan has been studied. 26 out of 30 fungal strains produced detectable amounts of auxins in tryptophan contain media. 18 strains produced but very small amounts of auxins in media without this amino acid.

Production of auxins by bacteria isolated from the roots of pine seedlings (Pinus silvestris L.).

Qualitative and quantitative studies were carried out on the production of auxins by Coryneform bacteria, the only bacterial types isolated from roots of pine seedlings. Almost all isolates were capable of producing auxins in tryptophan containing media. In media without this amino acid only trace or no auxins were produced.

Production of gibberellin-like substances by bacteria and fungi isolated from the roots of pine seedlings (Pinus silvestris L.).

The production of gibberellin-like substances by bacteria and fungi was investigated. A considerable number of the microorganisms studied produced these substances (55 and 86% of bacterial and fungal isolates respectively). Most of the organisms tested synthesized biologically active substances located on the chromatograms with the solvent system benzene, acetic acid (10:3 v/v) at Rf 0.
