Sauna Bathing

Components of the metabolic syndrome (i.e., hypertension, insulin resistance, obesity, atherosclerosis) are a leading cause of death in the United States and result in low-grade chronic inflammation, excessive oxidative stress, and the eventual development of cardiometabolic diseases (CMD). High-stress occupations (HSO: firefighters, police, military personnel, first responders, etc.) increase the risk of developing CMD because they expose individuals to chronic and multiple stressors (i.e., sleep deprivation, poor nutrition habits, lack of physical activity, psychological stress). Interestingly, heat exposure and, more specifically, sauna bathing have been shown to improve multiple markers of CMD, potentially acting as hormetic stressors, at the cellular level and in the whole organism. Therefore, sauna bathing might be a practical and alternative intervention for disease prevention for individuals with HSO. The purpose of this review is to detail the mechanisms and pathways involved in the response to both acute and chronic sauna bathing and collectively present sauna bathing as a potential treatment, in addition to current standard of care, for mitigating CMD to both clinicians and individuals serving in HSO.

In April 2020, at the onset of COVID-19 in the U.S., we implemented a weekly survey of underrepresented undergraduate students participating in a biomedical research training program. The 10-week survey collected qualitative and quantitative data on mental health, physical health, and financial health. Responses indicated high stress during the pandemic, particularly during the survey’s final weeks which occurred during a period of social unrest. Physical health declined throughout the survey, stabilizing in its final weeks. Financial health declined initially and stayed low throughout. Students from certain demographic groups, such as first generation college students and those with dependents were disproportionately impacted. Qualitative responses highlighted the intersectionality of the three constructs and illustrated the impacts of these events.

Indirect Relationship

A plethora of research has extolled the benefits of public service motivation (PSM) in public organizations. However, much less empirical attention has focused on its relationship to work stress. Even though it has been theorized that high levels of PSM causes individuals to be more resilient in stressful public service work environments, empirical research has failed to provide support. Only one study has been conducted which has revealed that high levels of PSM is directly associated with high levels of job stress among public employees, but that its beneficial effects are partially mediated by person-organization (PO) fit. That is, employees with high levels of PSM and high levels of fit to their organizations did not appear to suffer from high stress. This study sought to add to this limited body of research and explore the extent to which person-job (PJ) improves the field’s understanding of the relationships among PSM, PO fit, and work stress. Based on a sample of federal employees in the United States, this study challenged and confirmed the findings of existing research. For instance, PSM had no direct relationship to work stress. However, PSM maintained an indirect relationship to stress through PO fit. The respondents with high levels of PSM reported that they had high levels of fit to their organizations which was associated with significantly lower levels of work stress. Similarly, PSM was not directly related to PJ fit, but was indirectly related through its association with PO fit. PSM was associated with high levels of fit between employees and public organizations, which was subsequently associated with high levels of fit with public service jobs and lower work stress. Above all, this research clarifies the process of how PSM influences work stress among public employees, through PO fit and PJ fit.

Abstract Background Evidence is limited about the joint health effects of the Mediterranean lifestyle on cardiometabolic health and mortality. The aim of this study was to evaluate the association of the Mediterranean lifestyle with the frequency of the metabolic syndrome (MS) and the risk of all-cause and cardiovascular mortality in Spain. Methods Data were taken from ENRICA study, a prospective cohort of 11,090 individuals aged 18+ years, representative of the population of Spain, who were free of cardiovascular disease (CVD) and diabetes at 2008–2010 and were followed-up to 2017. The Mediterranean lifestyle was assessed at baseline with the 27-item MEDLIFE index (with higher score representing better adherence). Results Compared to participants in the lowest quartile of MEDLIFE, those in the highest quartile had a multivariable-adjusted odds ratio 0.73 (95% confidence interval (CI) 0.5, 0.93) for MS, 0.63. (0.51, 0.80) for abdominal obesity, and 0.76 (0.63, 0.90) for low HDL-cholesterol. Similarly, a higher MELDIFE score was associated with lower HOMA-IR and highly-sensitivity C-reactive protein (P-trend < 0.001). During a mean follow-up of 8.7 years, 330 total deaths (74 CVD deaths) were ascertained. When comparing those in highest vs. lowest quartile of MEDLIFE, the multivariable-adjusted hazard ratio (95% CI) was 0.58 (0.37, 0.90) for total mortality and 0.33 (0.11, 1.02) for cardiovascular mortality. Conclusions The Mediterranean lifestyle was associated with lower frequency of MS and reduced all-cause mortality in Spain. Future studies should determine if this also applies to other Mediterranean countries, and also improve cardiovascular health outside the Mediterranean basin.

The COVID-19 pandemic examines not only the state of actual health care but also the state of fundamental medicine in various countries. Pro-inflammatory processes extend far beyond the classical concepts of inflammation. They manifest themselves in a variety of ways, beginning with extreme physiology, then allostasis at low-grade inflammation, and finally the shockogenic phenomenon of “inflammatory systemic microcirculation”. The pathogenetic core of critical situations, including COVID-19, is this phenomenon. Microcirculatory abnormalities, on the other hand, lie at the heart of a specific type of general pathological process known as systemic inflammation (SI). Systemic inflammatory response, cytokine release, cytokine storm, and thrombo-inflammatory syndrome are all terms that refer to different aspects of SI. As a result, the metabolic syndrome model does not adequately reflect the pathophysiology of persistent low-grade systemic inflammation (ChSLGI). Diseases associated with ChSLGI, on the other hand, are risk factors for a severe COVID-19 course. The review examines the role of hypoxia, metabolic dysfunction, scavenger receptors, and pattern-recognition receptors, as well as the processes of the hemophagocytic syndrome, in the systemic alteration and development of SI in COVID-19.

Abstract Weaning imposes multiple stressors that reduce feed intake and impair intestinal integrity. Furthermore, poor environmental management could compound the high stress period increasing morbidity and mortality of postweaning piglets. The objective of this research was to investigate the effect of supplemental Saccharomyces cerevisiae (ActiSaf HR+®) on postweaning growth performance, fecal scores and immune parameters in a clean or dirty nursery environment. The experiment was a 2 X 2 factorial design with 2 dietary treatments fed in a sanitized (following barn SOP) and un-sanitized (pits flushed, feeders and pens scraped) nursery environment. Weaned piglets (n = 260 and 5pigs/pen; 14.7±1.5lbs wt., 20.8d of age) were allotted to the following dietary treatments: 1) control or 2) ActiSaf HR+® (0.1% in phase 1 and 2 and 0.05% phase 3 diets) for 5-wks postweaning. On days 3, 7, 14, 21 and 35 fecal scores/pen and blood samples were collected for monitoring diarrhea and measurement of cytokines. Overall, pigs fed ActiSaf tended towards greater ADG compared to control fed pigs regardless of environment (P = 0.09; 379 vs. 357 g/d, ActiSaf vs control, respectively). Final pen weights at d35 were greater in ActiSaf vs. control fed pigs (101 vs. 97 kg/pen; P &lt; 0.05). Pigs reared in the dirty vs clean environment had reduced overall ADG (352 vs 384 g/d, respectively; P = 0.01), and pigs in the dirty environment tended towards higher overall feed:gain compared to pigs in clean environments; 1.87 vs. 1.76 g/g (P = 0.09). Diarrhea scores were increased in the dirty environment compared to the clean environment on days 3 and 7 (P &lt; 0.01). Serum TNF-a concentrations were not significantly affected by diet or environment. In conclusion, nursery pigs raised in clean environments had higher ADG and improved feed conversion than pigs reared in a dirty environment. Pigs fed diets containing ActiSaf HR+® tended towards increased ADG regardless of environment.

Abstract Current standard of care therapy for glioblastoma (GBM) includes cytoreduction followed by ablative therapies that target rapidly dividing cell types. However, the presence of quiescent-like/G0 states, therefore, represents a natural reservoir of tumor cells that are resistant to current treatments. Quiescence or G0 phase is a reversible state of “stasis” cells enter in response to developmental or environmental cues. To gain insight into how glioblastoma cells might regulate G0-like states, we performed a genome-wide CRISPR-Cas9 screen in patient-derived GBM stem-like cells (GSCs) harboring a G0-reporter to identify genes that when inhibited trap GSCs in G0-like states. Among the top screen hits were members of the Tip60/KAT5 histone acetyltransferase complex, which targets both histones (e.g., H4) and non-histone proteins for acetylation. NuA4 functions as a transcriptional activator, whose activities are coordinated with MYC in certain contexts, and also participates in DNA double-strand break repair by facilitating chromatin opening. However, currently little is known about the roles for NuA4 complex in GBM biology. Through modeling KAT5 function in GSC in vitro cultures and in vivo tumors, we find that KAT5 inhibition causes cells to arrest in a G0-like state with high p27 levels, G1-phase DNA content, low protein synthesis rates, low rRNA rates, lower metabolic rate, suppression of cell cycle gene expression, and low histone H4 acetylation. Interestingly, partial inhibition of KAT5 activity slows highly aggressive tumor growth, while increasing p27hi H4-aclow populations. Remarkably, we that low grade gliomas have significantly higher H4-aclow subpopulations and generally lower H4-ac levels than aggressive grade IV tumors. Taken together, our results suggest that NuA4/KAT5 activity may play a key role in quiescence ingress/egress in glioma and that targeting its activity in high grade tumors may effectively “down grade” them, thus, increase patient survival.

AbstractIn 2019, the American Cancer Society (ACS) estimates that 174,650 new cases of prostate cancer will be diagnosed and 31,620 will die due to the prostate cancer in the United States. Prostate cancer is often managed with aggressive curative intent standard therapies including radiotherapy or surgery. Regardless of how expertly done, these standard therapies often bring significant risk and morbidity to the patient's quality of life with potential impact on sexual, urinary, and bowel functions. Additionally, improved screening programs, using prostatic-specific antigen and transrectal ultrasound-guided systematic biopsy, have identified increasing numbers of low-risk, low-grade “localized” prostate cancer. The potential, localized, and indolent nature of many prostate cancers presents a difficult decision of when to intervene, especially within the context of the possible comorbidities of aggressive standard treatments. Active surveillance has been increasingly instituted to balance cancer control versus treatment side effects; however, many patients are not comfortable with this option. Although active debate continues on the suitability of either focal or regional therapy for the low- or intermediate-risk prostate cancer patients, no large consensus has been achieved on the adequate management approach. Some of the largest unresolved issues are prostate cancer multifocality, limitations of current biopsy strategies, suboptimal staging by accepted imaging modalities, less than robust prediction models for indolent prostate cancers, and safety and efficiency of the established curative therapies following focal therapy for prostate cancer. In spite of these restrictions, focal therapy continues to confront the current paradigm of therapy for low- and even intermediate-risk disease. It has been proposed that early detection and proper characterization may play a role in preventing the development of metastatic disease. There is level-1 evidence supporting detection and subsequent aggressive treatment of intermediate- and high-risk prostate cancer. Therefore, accurate assessment of cancer risk (i.e., grade and stage) using imaging and targeted biopsy is critical. Advances in prostate imaging with MRI and PET are changing the workup for these patients, and advances in MR-guided biopsy and therapy are propelling prostate treatment solutions forward faster than ever.
