Implications of Compression Race Suit on Forced Vital Capacity: Assessment Considerations for Paradoxical Vocal Fold Motion in Competitive Female Swimmers.

Purpose The purpose of this investigation was to quantify the extent to which forced vital capacity (FVC) in competitive swimmers may differ from nonswimmers and determine if compression race suits reduced FVC when compared to practice swimsuits. Identification of the differences in FVC between swimmers and nonswimmers as well as pulmonary function differences secondary to swimsuit construction may inform assessment of the competitive swimmer with paradoxical vocal fold motion (PVFM). Method Using a prospective, mixed within- and between-groups, repeated measures design with 10 female competitive swimmers and 13 female nonswimmers, FVC was measured and compared between the two groups.

Emergency Medicine Residents on Electronic Medical Records: Perspectives and Advice.

Given the near-universal implementation of electronic medical records (EMRs) in emergency departments (EDs), emergency medicine (EM) residents spend significant time interfacing with EMRs without any established national curriculum to learn best practices. While EMRs have the potential to increase physician efficiency and improve the quality of documentation, they have also been cited as a factor in physician burnout. Understanding the target audience of the EMR, knowing what and when to chart, and practicing time-saving strategies can streamline the process of charting.

Delayed Diagnosis of Acromegaly in the Context of Post-Traumatic Stress Disorder due to Symptoms Mimicking Known Psychotropic Medication Side Effects.

Background: Acromegaly is caused by elevated secretion of human growth hormone, which is frequently because of intracranial tumors. This diagnosis is fairly uncommon with an incidence of 3 to 4 cases per million patients per year. We are presenting a case of acromegaly diagnosed in an active duty Chief Petty Officer.

Diagnosis and treatment of seborrheic dermatitis.

Seborrheic dermatitis is a common skin condition in infants, adolescents, and adults. The characteristic symptoms-scaling, erythema, and itching-occur most often on the scalp, face, chest, back, axilla, and groin. Seborrheic dermatitis is a clinical diagnosis based on the location and appearance of the lesions.

Midbrain dopamine neurons associated with reward processing innervate the neurogenic subventricular zone.

Coordinated regulation of the adult neurogenic subventricular zone (SVZ) is accomplished by a myriad of intrinsic and extrinsic factors. The neurotransmitter dopamine is one regulatory molecule implicated in SVZ function. Nigrostriatal and ventral tegmental area (VTA) midbrain dopamine neurons innervate regions adjacent to the SVZ, and dopamine synapses are found on SVZ cells.

Fitness epistasis among 6 biosynthetic loci in the budding yeast Saccharomyces cerevisiae.

We generated all possible haploid and homozygous diploid genotypes at 6 biosynthetic loci in yeast and scored their fitness to examine whether there was any pattern of weak synergistic epistasis, which is a requirement of the deterministic mutation model for the evolution of sex. We measured 4 components of fitness: haploid growth rate, haploid mating efficiency, diploid growth rate, and diploid sporulation efficiency. We found that in agreement with previous work in yeast, epistasis tended to be small in magnitude and variable in sign, regardless of the fitness component measured.

Growth of primary embryo cells in a microculture system.

We present optimal perfusion conditions for the growth of primary mouse embryonic fibroblasts (mEFs) and mouse embryonic stem cells (mESCs) using a microfluidic perfusion culture system. In an effort to balance nutrient renewal while ensuring the presence of cell secreted factors, we found that the optimal perfusion rate for culturing primary embryonic fibroblasts (mEFs) in our experimental setting is 10 nL/min with an average flow velocity 0.55 microm/s in the microchannel.
