Interleukin-15 and high-intensity exercise: relationship with inflammation, body composition and fitness in cancer survivors.

Pre-clinical murine and in vitro models have demonstrated that exercise suppresses tumour and cancer cell growth. These anti-oncogenic effects of exercise were associated with the exercise-mediated release of myokines such as interleukin (IL)-15. However, no study has quantified the acute IL-15 response in human cancer survivors, and whether physiological adaptations to exercise training (i.

Multi-Class Analysis of 57 Drugs Quantitatively in Blood and Qualitatively in Urine by LC-MS/MS to Complement Comprehensive DFC, DUID and Postmortem Testing.

A streamlined LC-MS/MS method utilizing protein precipitation and filtration extraction was developed to consolidate analyses for drug-facilitated crime (DFC), postmortem investigations, and driving under the influence of drugs (DUID) testing. Fifty-seven target drug and metabolite analytes eluted in under 6-minutes and compromised of GHB precursors (1), hallucinogens (3), muscle relaxants (3), anticonvulsants (7), antidepressants (20), antihistamines (5), antipsychotics (11), antihypertensives and alpha-adrenergics (3), analgesics and anesthetics (3), and miscellaneous (1) in blood (quantitatively) and urine (qualitatively). Limits of detection were set to meet the more challenging sensitivity requirements for DFC, and are therefore also suitable for postmortem investigations, and other forensic casework, including DUID.

Roadmap for low-carbon ultra-low temperature storage in biobanking.

Biobanks have become an integral part of health and bioscience research. However, the ultra-low temperature (ULT) storage methods that biobanks employ [ULT freezers and liquid nitrogen (LN2)] are associated with carbon emissions that contribute to anthropogenic climate change. This paper aims to provide a 'Roadmap' for reducing carbon emissions associated with ULT storage in biobanking.

Cancer-related cognitive impairment as a key contributor to psychopathology in cancer survivors: implications for prevention, treatment and supportive care.

A significant proportion of cancer survivors will experience some form of mental health compromise across domains including mood, anxiety, psychosis, eating disorders, and substance use. This psychopathology within cancer survivors is related to a range of negative outcomes and can also have a substantial negative impact on quality of life. Along with psychopathology, cognitive impairments are also commonly experienced, resulting in deficits in memory, reasoning, decision-making, speed of processing, and concentration, collectively referred to as cancer-related cognitive impairment (CRCI).

Molecular and Epidemiological Investigation of Fluconazole-resistant -Georgia, United States, 2021.

Background: Reports of fluconazole-resistant bloodstream infections are increasing. We describe a cluster of fluconazole-resistant bloodstream infections identified in 2021 on routine surveillance by the Georgia Emerging Infections Program in conjunction with the Centers for Disease Control and Prevention.

Methods: Whole-genome sequencing was used to analyze bloodstream infections isolates.

Effectiveness of 13-valent pneumococcal conjugate vaccine for prevention of invasive pneumococcal disease among children in the United States between 2010 and 2019: An indirect cohort study.

Background: A U.S. case-control study (2010-2014) demonstrated vaccine effectiveness (VE) for ≥ 1 dose of the thirteen-valent pneumococcal conjugate vaccine (PCV13) against vaccine-type (VT) invasive pneumococcal disease (IPD) at 86 %; however, it lacked statistical power to examine VE by number of doses and against individual serotypes.

Analysis of over 250 novel synthetic opioids and xylazine by LC-MS-MS in blood and urine.

Novel Synthetic Opioids (NSO) are frequently found in postmortem (PM) and human performance (HP) forensic toxicology casework, resulting in impairment and fatal overdoses. Developing a broad NSO method benefits public health, as it can be used to identify trends in potent opioid use to develop risk management programs. This project aimed to design a comprehensive, rapid and routine method for the selective analysis of over 250 novel synthetic opioids in blood and urine.

Genomic description of acquired fluconazole- and echinocandin-resistance in patients with serial isolates.

is one of the most common causes of systemic candidiasis, often resistant to antifungal medications. To describe the genomic context of emerging resistance, we conducted a retrospective analysis of 82 serially collected isolates from 33 patients from population-based candidemia surveillance in the United States. We used whole-genome sequencing to determine the genetic relationships between isolates obtained from the same patient.

Evaluating indwelling devices and other risk factors for mortality in invasive Carbapenem-resistant Enterobacterales infections in Georgia, 2012-2019.

Objective: Carbapenem-resistant Enterobacterales (CRE) infections are a public health threat due to the risk of transmission between patients and high associated mortality. We sought to identify risk factors for mortality in patients with invasive CRE infections and to specifically evaluate whether there was an association between indwelling medical devices and 90-day mortality.

Design: Retrospective observational cohort study of patients infected with CRE in the eight-county metropolitan Atlanta area between 2012 and 2019.

Biosymbiotic platform for chronic long-range monitoring of biosignals in limited resource settings.

Remote patient monitoring is a critical component of digital medicine, and the COVID-19 pandemic has further highlighted its importance. Wearable sensors aimed at noninvasive extraction and transmission of high-fidelity physiological data provide an avenue toward at-home diagnostics and therapeutics; however, the infrastructure requirements for such devices limit their use to areas with well-established connectivity. This accentuates the socioeconomic and geopolitical gap in digital health technology and points toward a need to provide access in areas that have limited resources.

Evaluation of Asymptomatic Bordetella Carriage in a Convenience Sample of Children and Adolescents in Atlanta, Georgia, United States.

Few data exist on asymptomatic carriage of Bordetella species among populations receiving acellular pertussis vaccine. We conducted a cross-sectional study among acellular-vaccinated children presenting to an emergency department (ED). Bordetella pertussis carriage prevalence was <1% in this population, a lower prevalence than that found in recent studies among whole-cell pertussis-vaccinated participants.

Understanding period poverty and stigma: Highlighting the need for improved public health initiatives and provider awareness.

Period poverty affects millions of people who menstruate, but there is limited research to fully understand the scope and impact. Societal stigmas and cultural taboos negatively affect menstruation, a natural, biologic process. When unable to afford or find appropriate menstrual products, individuals may resort to alternative, poorer quality items, which increase their risk of infections.

Sustainability and molecular biology: An interview with Martin Farley.

Molecular Cell has a conversation with Martin Farley about LEAF, the program he developed to run molecular biology laboratories in a sustainable way; the obstacles to making molecular biology sustainable; programs available to scientists; and caution to be exercised when taking steps towards sustainability.

Re-use of laboratory utensils reduces CO2 equivalent footprint and running costs.

Laboratory-based research is resource intensive in terms of financial costs and its carbon footprint. Research laboratories require immense amounts of energy to power equipment, as well as large volumes of materials, particularly of single-use item consumption. In fact, many laboratories have essentially become reliant on single-use plastics.

Coordinated stimulation of axon regenerative and neurodegenerative transcriptional programs by ATF4 following optic nerve injury.

Stress signaling is important for determining the fates of neurons following axonal insults. Previously we showed that the stress-responsive kinase PERK contributes to injury-induced neurodegeneration (Larhammar et al., 2017).

Context-aware electromagnetic design for continuously wearable biosymbiotic devices.

Imperceptible wireless wearable devices are critical to advance digital medicine with the goal to capture clinical-grade biosignals continuously. Design of these systems is complex because of unique interdependent electromagnetic, mechanic and system level considerations that directly influence performance. Typically, approaches consider body location, related mechanical loads, and desired sensing capabilities, however, design for real world application context is not formulated.

Immunomodulatory Function of Interleukin-15 and Its Role in Exercise, Immunotherapy, and Cancer Outcomes.

Exercise has been shown to improve physical and psychosocial outcomes for people across the cancer care continuum. A proposed mechanism underpinning the relationship between exercise and cancer outcomes is exercise-induced immunomodulation via secretion of anti-inflammatory myokines from skeletal muscle tissue. Myokines have the potential to impair cancer growth through modulation of natural killer (NK) cells and CD8+ T cells while improving the effectiveness of cancer therapies.
