Salmonella enterica in Invasive Lizard from Fernando de Noronha Archipelago: Serotyping, Antimicrobial Resistance and Molecular Epidemiology

Salmonella infection can pose serious health issues, especially to children, elders or immunosuppressed humans. Wild populations of reptiles can reach Salmonella prevalence of up to 100% and the direct or indirect transmission from reptiles to humans have been extensively reported. Fernando de Noronha (FN) is an inhabited oceanic archipelago in the northeast coast of Brazil, with an economy based on tourism. The tegu (Salvator merianae) is the largest lizard native to South America and was introduced to the archipelago in the early 20th century. This study determines the prevalence, serotypes, antimicrobial resistance, and molecular epidemiology of Salmonella enterica in the tegu population from FN archipelago. Results show that S. enterica is widely distributed in the FN tegu population, with 43.8% prevalence. The bacteria were isolated from 70.5% of the sampled sites and a total of 15 serotypes were detected in 98 S. enterica isolates. Strains were further classified into 31 genotypes. Recaptured animals presented distinct genotypes in each season, demonstrating a seasonal strain turnover. Most S. enterica isolates from FN tegus presented low antimicrobial resistance. This is possibly due to geographical isolation of the island population, hampering contact with strains from livestock from the continent, where antimicrobial resistance is common.
Novel Liver X Receptor Ligand GAC0001E5 Disrupts Glutamine Metabolism and Induces Oxidative Stress in Pancreatic Cancer Cells

Pancreatic ductal adenocarcinoma (PDAC) is the predominant form of pancreatic cancer with a high mortality rate due to the lack of early detection and effective treatment options for advanced diseases. Metabolic reprogramming, a common hallmark of malignant transformation in pancreatic cancer, is critical for the growth and survival of cancer cells and a potential target mechanism for the treatment of pancreatic cancer. PDAC cells have upregulated glutamine metabolism to meet their biosynthetic and oxidative demands. Liver X receptors (LXRs) are ligand-dependent transcription factors involved in maintaining metabolic homeostasis. LXRs regulate critical cancer-related processes and pathways, including cholesterol, glucose and lipid metabolism, and inflammatory and immune responses. Analysis of transcriptomic data from PDAC clinical samples reveals overexpression of LXRs and their target genes in tumors as compared to normal tissue controls. Targeting LXRs with the novel LXR inverse agonist and degrader GAC0001E5 inhibited PDAC cell proliferation. Using a metabolomics approach, we discovered that 1E5 inhibits glutamine anaplerosis and induces oxidative stress, which are detrimental to PDAC cells. These findings highlight a novel role for LXR in regulating cancer metabolism and the potential application of LXR modulators in targeting cancer metabolism in pancreatic cancer and other malignancies.
Gas and liquid fuel injection into an enclosed swirling flow

A swirler with good premixed performance has been tested with direct central propane injection and with direct central kerosene and gas oil injection using the swirler air for atomisation. The results have been compared with non swirling flow systems at the same test conditions. Direct propane injection results in a major extension of the stability limits compared with the premixed situation, but with liquid fuel injection the stability limits are generally worse than for premixed fuel and air. It is argued that the cause of this is the action of the centrifugal forces on the liquid droplets in the swirl flow which results in vaporisation in the outer swirl flow and weaker mixtures in the core recirculation region than for propane injection. The gas composition results support this conclusion. Direct propane injection caused a deterioration in the combustion efficiency and a large increase in NOx. The poor stability limits with liquid fuels prevented a high combustion efficiency and low NOx situation from being achieved. A comparison of the performance with non swirling systems showed that all emissions were higher with swirl for propane but that the swirler may have some advantages for liquid fuels.Copyright © 1984 by ASME
Eukaryotic and Prokaryotic Microbiota Interactions

The nature of the relationship between the communities of microorganisms making up the microbiota in and on a host body has been increasingly explored in recent years. Microorganisms, including bacteria, archaea, viruses, parasites and fungi, have often long co-evolved with their hosts. In human, the structure and diversity of microbiota vary according to the host’s immunity, diet, environment, age, physiological and metabolic status, medical practices (e.g., antibiotic treatment), climate, season and host genetics. The recent advent of next generation sequencing (NGS) technologies enhanced observational capacities and allowed for a better understanding of the relationship between distinct microorganisms within microbiota. The interaction between the host and their microbiota has become a field of research into microorganisms with therapeutic and preventive interest for public health applications. This review aims at assessing the current knowledge on interactions between prokaryotic and eukaryotic communities. After a brief description of the metagenomic methods used in the studies were analysed, we summarise the findings of available publications describing the interaction between the bacterial communities and protozoa, helminths and fungi, either in vitro, in experimental models, or in humans. Overall, we observed the existence of a beneficial effect in situations where some microorganisms can improve the health status of the host, while the presence of other microorganisms has been associated with pathologies, resulting in an adverse effect on human health.
Patterns of Current Cigarette Smoking, Quit Attempts, and Cessation Counseling Among Survivors of Smoking Related and Non-smoking Related Urologic Malignancies: A Nationally Representative Cross-Sectional Analysis.

INTRODUCTION AND OBJECTIVE Cigarette smoking is the leading modifiable risk factor for several genitourinary (GU) malignancies. Although smoking cessation after GU cancer diagnosis is a critical component of survivorship, factors related to continued smoking are understudied. METHODS A cross-sectional analysis was conducted using data from the NHIS (2014-2018). Our primary study outcome was the prevalence and correlates of cigarette smoking among adults with history of smoking-related (kidney or bladder) urologic cancer compared with a nonsmoking-related control (prostate cancer). We used regression analyses to assess the association of having a smoking-related GU cancer history with continued cigarette smoking after diagnosis. Secondary outcomes were yearly smoking trends, quit attempts and reported receipt of smoking cessation counseling. RESULTS A total of 2,664 respondents reported a history of a GU cancer, representing weighted estimates of 990,820 (smoking-related GU cancer) and 2,616,596 (prostate cancer) adults. Survivors of smoking-related GU cancers had a significantly higher overall prevalence of current cigarette use (14.8% vs 8.6%, p <0.001) and also reported more frequent receipt of counseling (79.8% vs 66.2%, p=0.02) but did not attempt to quit any more often than those with prostate cancer (52.4% vs 47.2%, p=0.44). Time trends demonstrated stable and persistent cigarette use among survivors of all GU cancers. After adjustment for sociodemographic confounders, cancer type was not associated with current cigarette smoking (OR 1.23, 95% CI 0.86-1.77). However, older age and more advanced educational attainment were associated with lower odds of current cigarette smoking while single marital status was associated with higher odds. CONCLUSIONS In this population-based cross-sectional study of survivors of GU cancers, those with a reported smoking-related GU cancer had a higher prevalence of current cigarette smoking compared to prostate cancer, our nonsmoking related control. Those with smoking-related GU cancers reported more frequent receipt of smoking cessation counseling.
Other- and All-Cause Mortality Among Men Diagnosed with Prostate Cancer in the PLCO Trial.

PURPOSE Men with prostate cancer (PCa) have high cause-specific survival, and most deaths are of other causes. This study aimed to investigate other- and all-cause mortality in a large cancer screening cohort. MATERIALS AND METHODS From the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial cohort, we selected men diagnosed with PCa from 1994-2014. We examined other- and all-cause survival by PCa risk level, defined as the D'Amico categories for localized disease (low-, intermediate- and high-risk) plus non-localized disease. We developed three Cox proportional hazards models to assess the relationship between risk level and survival. Model I controlled for age, race, study arm, and diagnosis year. Model II additionally controlled for other demographic and medical history factors; Model III additionally controlled for initial treatment. RESULTS Of 76,672 men in PLCO and 10,859 PCa cases, 9248 (85.2%) had known PCa risk level (mean (SD) age 70.4 (6.2) years). Median (25th/75th) follow-up time from diagnosis was 10.8 (6.8/15.0) years. Of 3318 deaths, 81% were from other-causes. Compared to the low-risk group, other-cause mortality HRs were 1.13 (95% CI: 1.04-1.23), 1.35 (95% CI: 1.21-1.50), and 1.63 (95% CI: 1.35-1.97), for intermediate-risk, high-risk, and advanced disease, respectively in Model II. Model III HRs were similar to Model II except for advanced disease, where the HR decreased to 1.35. CONCLUSIONS Other-cause survival was higher in lower compared to higher risk disease, even after controlling for lifestyle characteristics and comorbidities. Further research is needed to identify factors contributing to this higher other-cause mortality to help mitigate the risk.
Substrate stiffness tunes the dynamics of polyvalent rolling motors.

Nature has evolved many mechanisms for achieving directed motion on the subcellular level. The burnt-bridges ratchet (BBR) is one mechanism used to achieve superdiffusive molecular motion over long distances through the successive cleavage of surface-bound energy-rich substrate sites. This mechanism has been associated with both nanoscale and microscale movement, with the latter accomplished through polyvalent interactions between a large hub (e.g. influenza virus) and substrate (e.g. cell surface receptors). Experimental successes in achieving superdiffusive motion by synthetic polyvalent BBRs have raised questions about the dynamics of their motility, including whether rolling or translation is better able to direct motion of microscale spherical hubs. Here we simulate the three-dimensional dynamics of a polyvalent sphere moving on and cleaving an elastic substrate. We find that substrate stiffness plays an important role in controlling both the motor's mode of motility and its directional persistence. As we tune lateral substrate stiffness from soft to stiff we find there exists an intermediate value that optimizes rolling behaviour. We also find that there is an optimal substrate stiffness for maximizing persistence length, while stiffness does not influence as strongly the superdiffusive dynamics of the particle. Lastly, we examine the effect of substrate density, and show that softer landscapes are better able to buffer against decreases in substrate occupancy, with the spherical motor maintaining superdiffusive motion more on softer landscapes than on stiff landscapes as occupancy drops. Our results highlight the importance of surface in controlling the motion of polyvalent BBRs.
High-density lipoprotein cholesterol and arterial calcification in midlife women: the contribution of estradiol and C-reactive protein.

OBJECTIVE Studies suggest a reversal in the protective association of high-density lipoprotein cholesterol (HDL-C) and cardiovascular disease in women traversing menopause. Decreasing estrogen levels during the transition, as well as inflammation, may explain this reversal. We tested whether either estradiol or C-reactive protein (CRP) concentrations modified the association of HDL-C with aortic (AC) or coronary artery calcification (CAC). METHODS A total of 478 participants between ages 46 to 59 from the Study of Women's Health Across the Nation Heart baseline visit were included. AC and CAC presence were defined as Agatston score of 100 or higher and 10 or higher, respectively. Logistic regression was used for analysis. RESULTS A total of 112 (23.53%) participants had AC 100 or higher and 104 (21.76%) had CAC 10 or higher. In unadjusted models, a 1-mg/dL higher in HDL-C was associated with 3% lower odds of AC (95% CI: 0.95-0.99) and 4% lower odds of CAC (95% CI: 0.95-0.98). In adjusted models, a significant interaction between HDL-C and estradiol with respect to AC but not CAC was detected, such that higher HDL-C level was protective at the highest estradiol quartile (odds ratio: 0.91, 95% CI: 0.84-0.99 per 1 mg/dL higher HDL-C, P = 0.03) but tended to associate with greater risk at the lowest quartile (odds ratio: 1.04, 95% CI: 0.98-1.10 per 1 mg/dL higher HDL-C, P = 0.16). CRP did not modify any association. CONCLUSIONS The protective cardiovascular association of higher HDL-C levels on AC was modified by estradiol but not CRP concentrations. The pathways through which estradiol might influence this association should be further investigated. Video Summary:http://links.lww. com/MENO/A689.
Genetic diagnosis of infantile‐onset epilepsy in the clinic: Application of whole‐exome sequencing following epilepsy gene panel testing

This study aimed to evaluate the clinical utility of whole‐exome sequencing in a group of infantile‐onset epilepsy patients who tested negative for epilepsy using a gene panel test. Whole‐exome sequencing was performed on 59 patients who tested negative on customized epilepsy gene panel testing. We identified eight pathogenic or likely pathogenic sequence variants in eight different genes (FARS2, YWHAG, KCNC1, DYRK1A, SMC1A, PIGA, OGT, and FGF12), one pathogenic structural variant (8.6 Mb‐sized deletion on chromosome X [140 994 419–149 630 805]), and three putative low‐frequency mosaic variants from three different genes (GABBR2, MTOR, and CUX1). Subsequent whole‐exome sequencing revealed an additional 8% of diagnostic yield with genetic confirmation of epilepsy in 55.4% (62/112) of our cohort. Three genes (YWHAG, KCNC1, and FGF12) were identified as epilepsy‐causing genes after the original gene panel was designed. The others were initially linked with mitochondrial encephalopathy or different neurodevelopmental disorders, although an epilepsy phenotype was listed as one of the clinical features. Application of whole‐exome sequencing following epilepsy gene panel testing provided 8% of additional diagnostic yield in an infantile‐onset epilepsy cohort. Whole‐exome sequencing could provide an opportunity to reanalyze newly recognized epilepsy‐linked genes without updating the gene panel design.
Knowing you are there makes the difference: perceived social support, preferences for using support, and health

ABSTRACT Using cluster analysis, we investigated whether perceived social support and individual differences in preferences to use support combined to form distinct profiles. Self-report data were collected from U.S. adults (N = 454; aged 40–90, M age = 55.37, SD = 9.73). Four profiles were identified: disengaged, interpersonally connected, isolated independent, and connected independent. Profiles characterized by high perceived support were associated with better overall health, even among those who preferred not to use support; men and those not married or cohabiting were less likely to be in these profiles. Implications for understanding associations between social support and health and the identification of at-risk groups are discussed.
Neuroplasticity in N‐methyl‐d‐aspartic acid receptor signaling in subregions of the rat rostral ventrolateral medulla following sedentary versus physically active conditions

The rostral ventrolateral medulla (RVLM) is a brain region involved in normal regulation of the cardiovascular system and heightened sympathoexcitatory states of cardiovascular disease (CVD). Among major risk factors for CVD, sedentary lifestyles contribute to higher mortality than other modifiable risk factors. Previous studies suggest excessive glutamatergic excitation of presympathetic neurons in the RVLM occurs in sedentary animals. Therefore, the purpose of this study was to examine neuroplasticity in the glutamatergic system in the RVLM of sedentary and physically active rats. We hypothesized that relative to active rats, sedentary rats would exhibit higher expression of glutamate N‐methyl‐d‐aspartic acid receptor subunits (GluN), phosphoGluN1, and the excitatory scaffold protein postsynaptic density 95 (PSD95), while achieving higher glutamate levels. Male Sprague–Dawley rats (4 weeks old) were divided into sedentary and active (running wheel) conditions for 10–12 weeks. We used retrograde tracing/triple‐labeling techniques, western blotting, and magnetic resonance spectroscopy. We report in sedentary versus physically active rats: 1) fewer bulbospinal non‐C1 neurons positive for GluN1, 2) significantly higher expression of GluN1 and GluN2B but lower levels of phosphoGluN1 (pSer896) and PSD95, and 3) higher levels of glutamate in the RVLM. Higher GluN expression is consistent with enhanced sympathoexcitation in sedentary animals; however, a more complex neuroplasticity occurs within subregions of the ventrolateral medulla. Our results in rodents may also indicate that alterations in glutamatergic excitation of the RVLM contribute to the increased incidence of CVD in humans who lead sedentary lifestyles. Thus, there is a strong need to further pursue mechanisms of inactivity‐related neuroplasticity in the RVLM.
The Clinical Course of Coronavirus Disease 2019 in a US Hospital System: A Multistate Analysis

Abstract There are limited data on longitudinal outcomes for coronavirus disease 2019 (COVID-19) hospitalizations that account for transitions between clinical states over time. Using electronic health record data from a hospital network in the St. Louis, Missouri, region, we performed multistate analyses to examine longitudinal transitions and outcomes among hospitalized adults with laboratory-confirmed COVID-19 with respect to 15 mutually exclusive clinical states. Between March 15 and July 25, 2020, a total of 1,577 patients in the network were hospitalized with COVID-19 (49.9% male; median age, 63 years (interquartile range, 50–75); 58.8% Black). Overall, 34.1% (95% confidence interval (CI): 26.4, 41.8) had an intensive care unit admission and 12.3% (95% CI: 8.5, 16.1) received invasive mechanical ventilation (IMV). The risk of decompensation peaked immediately after admission; discharges peaked around days 3–5, and deaths plateaued between days 7 and 16. At 28 days, 12.6% (95% CI: 9.6, 15.6) of patients had died (4.2% (95% CI: 3.2, 5.2) had received IMV) and 80.8% (95% CI: 75.4, 86.1) had been discharged. Among those receiving IMV, 35.1% (95% CI: 28.2, 42.0) remained intubated after 14 days; after 28 days, 37.6% (95% CI: 30.4, 44.7) had died and only 37.7% (95% CI: 30.6, 44.7) had been discharged. Multistate methods offer granular characterizations of the clinical course of COVID-19 and provide essential information for guiding both clinical decision-making and public health planning.
Venous Thromboembolism in Patents With Lung Cancer

Lung cancer is the leading cause of death from cancer in Japan. Studies in other countries have reported a venous thromboembolism (VTE) rate of 4%–20% in cancer patients. In this study, we aimed to determine the incidence of VTE in lung cancer patients in Japan and compared the characteristics of patients with and without VTE. In this retrospective cohort study, the clinicopathological characteristics of study patients with and without concomitant VTE were compared. Patients with lung cancer treated at Fukui Prefectural Hospital, Japan from 2008 to 2017. Of the 1471 patients with lung cancer studied, 28 developed VTE. Five patients developed pulmonary thromboembolism (PTE) alone, 9 PTE with concomitant deep vein thrombosis, and 14 deep vein thrombosis alone. Compared with patients in the non-VTE group, the VTE group was significantly younger (mean value ± SD 66.3 ± 10.1 vs. 73.0 ± 10.6 years, p = 0.001), contained significantly more patients with stage IIIb–IV disease (p = 0.002), and had a significantly higher rate of chemotherapy (p < 0.001) and radiation therapy (p = 0.007). There was no significant difference in median survival time from lung cancer diagnosis between the VTE and non-VTE groups. The 1-year mortality rate after VTE diagnosis was 60.7%. Lung cancer was the most frequent cause of death, followed by infection and VTE. Several baseline characteristics differed between patients with and without VTE. The prognosis may worsen after development of VTE, suggesting that lung cancer patients should be carefully monitored for it.
Personality Profiles and Psychological Adjustment in Breast Cancer Patients

Dispositional personality characteristics may play a role in psychosocial adjustment to any disease, including cancer. Purpose: The purpose of this study is to identify personality profiles in breast cancer patients and to determine whether these profiles are associated with psychological adjustment or psychopathology. Methods: Participants were 109 women (mean age, 52.01) diagnosed with breast cancer. They completed the Millon Clinical Multiaxial Inventory-III (MCMI-III), the Life Orientation Test-Revised (LOT-R), the Satisfaction with Life Scale, and the Positive and Negative Affect Scales. Results: The analysis revealed two different personality profiles: (a) one group, comprising 38.23% of the sample, was characterized by paranoid, negativistic, and dependent personality traits and was considered as a “vulnerable group”; and (b) another group (61.77%) was characterized by compulsive, histrionic, and narcissistic personality traits and was considered as a “psychologically adjusted group”. The vulnerable group scored higher than the psychologically adjusted group on all clinical syndromes, with scores above 60 on the anxiety, somatoform, dysthymic, and bipolar scales (score on anxiety being above 75); in contrast, the psychologically adjusted group did not reach a base rate score of 60 on any of the clinical syndromes, showing no manifestations of psychopathology. Additionally, the vulnerable group scored lower than the psychologically adjusted group on optimism, life satisfaction, and positive affect, but higher on negative affect. Conclusions: The results suggest that personality traits could affect the psychological adjustment of breast cancer survivors. We discuss the implications of belonging to each group and highlight the importance of early identification of vulnerable women in order to facilitate clinical and psychological support.
