Human populations are experiencing unprecedented growth and longevity with lingering knowledge gaps of the characteristics, mechanisms, and pathologies of senescence. Invasive measurements and long-term control conditions for longitudinal studies are infeasible, necessitating the need for surrogate animal models. Rats have short lifespans (2-3 years) with translatable cardiovascular systems, and Sprague Dawley microcirculatory preparations are key to studying the oxygen transport mechanisms critical to the loss of skeletal muscle function in aging.

Congenital cytomegalovirus is a leading cause of neurodevelopmental impairment and sensorineural hearing loss. We evaluated infants ≤21 days postnatal age who had both urine and saliva cytomegalovirus testing and determined concordance between the 2 tests and influence of very low birth weight on concordance. Discordance was low overall between urine and saliva testing; however, discordance was high in very low birth weight infants.

Background: The Antimicrobial Resistance Laboratory Network (AR Lab Network) was developed by the CDC to detect emerging antimicrobial-resistant (AR) threats and prevent outbreaks. However, low submission rates of AR isolates limit the potential of the AR Lab Network to address antimicrobial resistance (AMR).

Aim: The aim of this study was to investigate barriers to submission of AR isolates in acute care hospitals (ACHs) and critical access hospitals (CAHs) within Texas Public Health Region 8 (PHR8) counties.

Background And Objectives: Packed red blood cell transfusions (pRBCT) in preterm infants have been associated with significant morbidity. Although infants <26 weeks' gestational age typically require several pRBCT, preterm infants born between 26 and 34 weeks' gestational age may also require pRBCT during their hospitalization that are potentially preventable. We aimed to reduce pRBCT in this population by 20%.

Article Synopsis
  • Brain injury is closely linked to preterm birth, with complications like intestinal perforations contributing to long-term neurological issues that are not well understood.
  • The study found that subventricular zone echogenicity (SVE) on cranial ultrasound in preterm infants after intestinal perforations was associated with motor impairment at age 2.
  • Research in a neonatal mouse model showed that SVE involves specific cellular changes, suggesting that ultrasound detection of SVE could be an early indicator of neurodevelopmental impairment in preterm infants experiencing inflammatory conditions.

This study examined changes in interstitial PO, which allowed calculation of VO during periods of rest, muscle contraction and recovery using an rat spinotrapezius muscle preparation. The PO was measured using phosphorescence quenching microscopy and the muscle VO was calculated as the rate of O disappearance during brief periods of muscle compression to stop blood flow with a supra-systolic pressure. The PO and VO measurements were made during "5 s compression and 15 s recovery" (CR) cycles.

The ability to encode (spell) is an integral writing skill needed to communicate effectively. The ability to spell, also, enhances decoding as spelling and decoding are reciprocal skills that rely on knowledge of the same subskills. Spelling can also be particularly difficult for students with literacy and phonological-processing difficulties such as dyslexia.

This retrospective study of 68 premature infants examined whether there was a difference between male and female mixed-sex multiple gestation infants with regard to stage of retinopathy of prematurity (ROP) developed or need for ROP treatment. We found that among mixed-sex twin infants there was no statistically significant difference between sexes in most severe ROP stage developed or need for ROP treatment, but males were treated at an earlier postmenstrual age (PMA) than females, despite females having a lower mean birthweight and slower mean growth velocity compared to males.

Drug-resistant variants of herpes simplex viruses (HSV) have been reported that are not effectively treated with first-line antiviral agents. The objective of this study was to evaluate available literature on the possible efficacy of second-line treatments in HSV and the use of second-line treatments in HSV strains that are resistant to first-line treatments. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a final search was conducted in six databases on November 5, 2021 for all relevant literature using terms related to antiviral resistance, herpes, and HSV.

The ability to store red blood cells (RBCs) and other components for extended periods of time has expanded the availability and use of transfusion as a life-saving therapy. However, conventional RBC storage has a limited window of effective preservation and is accompanied by the progressive accumulation of a series of biochemical and morphological modifications, collectively referred to as "storage lesions." These lesions have been associated with negative clinical outcomes (i.

The current paper expands an under-addressed concept within the job insecurity literature, namely, whether threats to job security are specific to the jobholder (person-at-risk threats) or specific to the job (job-at-risk threats). Using a between-person experimental vignette design, 136 employed participants were asked to imagine themselves in either a Person-at-Risk or a Job-at-Risk scenario. As expected, participants in a person-at-risk scenario indicated more negative reactions to job insecurity, as captured by greater anticipated negative affect and poorer perceived social exchanges and organization-based self-esteem.

The effects of the COVID-19 pandemic on essential service workers has given rise to their newfound "hero" status, resulting in a dramatic shift of their occupational value. Service work has been long envisioned as "dirty work", and further, stigmatized by members of society (the Out-Group), until recently. This study utilized occupational stigma theory to identify the mechanisms under which both essential service workers and society at large came to unify around the importance of perceived dirty work in the United States.

August Krogh twice won the prestigious international Steegen Prize, for nitrogen metabolism (1906) and overturning the concept of active transport of gases across the pulmonary epithelium (1910). Despite this, at the beginning of 1920, the consummate experimentalist was relatively unknown worldwide and even among his own University of Copenhagen faculty. But, in early 1919, he had submitted three papers to Dr Langley, then editor of The Journal of Physiology in England.

The invention of the phosphorescence quenching method for the measurement of oxygen concentration in blood and tissue revolutionized physiological studies of oxygen transport in living organisms. Since the pioneering publication by Vanderkooi and Wilson in 1987, many researchers have contributed to the measurement of oxygen in the microcirculation, to oxygen imaging in tissues and microvessels, and to the development of new extracellular and intracellular phosphorescent probes. However, there is a problem of congruency in data from different laboratories, because of interlaboratory variability of the calibration coefficients in the Stern-Volmer equation.

Under physiologic conditions, microvascular oxygen delivery appears to be well matched to oxygen consumption in respiring tissues. We present a technique to measure interstitial oxygen tension (PISFO2) and oxygen consumption (VO2) under steady-state conditions, as well as during the transitions from rest to activity and back. Phosphorescence Quenching Microscopy (PQM) was employed with pneumatic compression cycling to achieve 1 to 10 Hz sampling rates of interstitial PO2 and simultaneous recurrent sampling of VO2 (3/min) in the exteriorized rat spinotrapezius muscle.
