Anxiety levels in patients admitted to the emergency department with myocardial infarction or COVID-19 pneumonia

ABSTRACT The COVID-19 related high morbidity and mortality have led to a common fear and anxiety. This study aimed to determine the state/trait and death anxiety levels of patients with myocardial infarction (MI) and COVID-19 pneumonia. The study was conducted at the emergency department of a tertiary hospital in Central Anatolia of Turkey. 120 patients with myocardial infarction , 120 patients with COVID-19 pneumonia, and 120 healthy volunteers as a control group were included in the study. The participants filled out the questionnaire that included the State-Trait Anxiety Inventory (STAI) and the Thorson–Powell’s Revised Death Anxiety Scale (RDAS). All scores of patient groups were significantly higher than the control group. There was no significant difference in terms of STAI-S, STAI-T, and RDAS scores between COVID-19 pneumonia and MI groups. The anxiety risk increased 2.14-fold for STAI-T and 1.97-fold for STAI-S in patients with COVID-19 pneumonia compared to the control group. In this study, the state/trait and death anxiety levels of patients with COVID-19 pneumonia were as high as patients with myocardial infarction.COVID-19 pneumonia-related anxiety was associated with chronic diseases and smoking. Knowing the level of anxiety in these patients is important to provide better health services in the emergency departments.
Two intronic cis‐acting variants in both alleles of the POLR3A gene cause progressive spastic ataxia with hypodontia

POLR3A encodes the largest subunit of the DNA‐dependent RNA polymerase III. Pathogenic variants in this gene are associated with dysregulation of tRNA production and other non‐coding RNAs. POLR3A‐related disorders include variable phenotypes. The genotype–phenotype correlation is still unclear. Phenotypic analysis and exome sequencing were performed in four affected siblings diagnosed clinically with hereditary spastic ataxia, two healthy siblings and their unaffected mother. All four affected siblings (ages 46–55) had similar clinical features of early childhood‐onset hypodontia and adolescent‐onset progressive spastic ataxia. None had progeria, gonadal dysfunction or dysmorphism. All affected individuals had biallelic POLR3A pathogenic variants composed by two cis‐acting intronic splicing‐altering variants, c.1909 + 22G > A and c.3337–11 T > C. The two healthy siblings had wild‐type alleles. The mother and another unaffected sibling were heterozygous for the allele containing both variants. This is the first report addressing the clinical consequence associated with homozygosity for a unique pathogenic intronic allele in the POLR3A gene. This allele was previously reported in compound heterozygous combinations in patients with Wiedemann‐Rautenstrauch syndrome, a severe progeroid POLR3A‐associated phenotype. We show that homozygosity for this allele is associated with spastic ataxia with hypodontia, and not with progeroid features. These findings contribute to the characterization of genotype–phenotype correlation in POLR3A‐related disorders.
Comparison of procedural efficacy and biophysical parameters between two competing cryoballoon technologies for pulmonary vein isolation: Insights from an initial multicenter experience

Recently a novel cryoballoon system (POLARx, Boston Scientific) became available for the treatment of atrial fibrillation. This cryoballoon is comparable with Arctic Front Advance Pro (AFA‐Pro, Medtronic), however, it maintains a constant balloon pressure. We compared the procedural efficacy and biophysical characteristics of both systems.
Root-derived inputs are major contributors to soil carbon in temperate forests

Roots promote the formation of slow-cycling soil carbon (C), yet we have limited understanding of the magnitude and controls on this flux. We hypothesized that root-derived inputs from ectomycorrhizal (ECM)-associated trees would be greater than those from arbuscular mycorrhizal (AM)-associated trees, and that soils receiving the greatest inputs would promote greater root-derived C accumulation in mineral-associated pools. We installed δ13C-enriched ingrowth cores across mycorrhizal gradients in six Eastern U.S. forests (n = 54 plots). Counter to our hypothesis, root-derived C was 54% greater in AM versus ECM-dominated plots, resulting in 175% more root-derived C in mineral-associated, slow-cycling pools in AM compared to ECM plots. Notably, root-derived soil C was comparable in magnitude to leaf litter inputs and aboveground net primary production. Our results suggest that variation in root-derived C inputs due to tree mycorrhizal dominance may be a key control of soil C dynamics in forests.
Toward a Universal Acute Fish Threshold of Toxicological Concern

Threshold of toxicological concern (TTC) is a concept that has been around for decades in human health sciences. Ecotoxicology recently adopted a variant of this concept as eco‐TTC. Adoption of the concept of TTC considerably reduces the amount of animal testing required for regulatory purposes. We provide an application of a universal TTC for the entirety of acute fish toxicity data (i.e., establishment of an exposure level below which there would be minimal probability of acute fish toxicity for any chemical, without consideration of mechanism of action). We calculated TTC values for a number of subgroups using various approaches. These approaches were evaluated using data from a cohort of 69 999 acute fish toxicological assays. This database was normalized/curated for units, exposure duration, quality assurance/control, and duplicates, which reduced it to 47 694 assays. Data were not normally but log‐normally distributed, making geometric means the most appropriate statistical parameter. Thus, we developed descriptive statistics using geometric means with 95, 99, and 99.9% confidence intervals. Various assessment factors (akin to predicted‐no‐effect concentration derivation) were applied to the geometric means to derive TTCs. Other approaches employed were the calculation of y = 0 intercepts as well as development of 95 and 99.75% cutoffs of cumulative data as well as modular uncertainty scoring tool (MUST) analysis. All of the methodologies derived highly congruent TTCs ranging from to 2 to 8 μg/L except for the 99.75th percentile cutoff of 0.3 μg/L. The data would be most useful in making a binary testing/no testing required decision. For acute fish toxicity, a TTC value of 2 μg/L was most appropriate, based on the 95th percentile of data distribution without any assessment factor.

How selecting best upfront therapy for metastatic disease?—Focus on ROS1-rearranged disease

ROS proto-oncogene 1 (ROS1) rearrangements defines a distinct group of non-small cell lung cancer (NSCLC), mainly represented by younger subjects, never smokers and with adenocarcinoma histology. Fusions involving ROS1 gene are present in 1-2% of lung adenocarcinomas and other solid tumors. Identification of patients harboring ROS1 rearrangements is a critical issue and current guidelines recommend screening of all advanced non-squamous NSCLC and certain squamous lung cancer patients. A number of trials have supported crizotinib as the best option for NSCLC patients with ROS1 translocations, irrespective of line of therapy. Unfortunately, the majority of patients become insensitive to crizotinib, due to the occurrence of secondary ROS1 mutations or failure within the central nervous system (CNS). Several highly potent and CNS penetrant ROS1 inhibitors have been developed and recent data highlight their potential role in the front-line treatment of this disease. Among them entrectinib, also known as RXDX-101, is a potent second-generation, multitarget oral inhibitor against the neurotrophin receptors TRKA, TRKB, TRKC ALK, and ROS1 with the ability to cross the blood-brain barrier. In the next few years, results of ongoing trials with novel ROS1 inhibitors and dedicated translational research studies might help to define the optimal sequence of treatment for ROS1-positive NSCLC patients.
Immunotherapy beyond progression in patients with advanced non-small cell lung cancer

Background Immune checkpoint inhibitors (ICIs) represent a great breakthrough in the treatment of advanced non-small cell lung cancer (aNSCLC). However, whether immunotherapy beyond progression (IBP) is effective for aNSCLC has yet to be established. Therefore, a retrospective clinical study was conducted to investigate the efficacy of IBP in patients with aNSCLC under real-world conditions. Methods A total of 125 Chinese patients with aNSCLC who experienced progressive disease (PD) after receiving monotherapy or combination therapy (combined with chemotherapy or/and antiangiogenic therapy) with programmed cell death-1 (PD-1)/programmed cell death ligand-1 (PD-L1) inhibitors between January 2015 and March 2019 were enrolled. Patients who were treated with ICIs for more than 6 weeks after PD were defined as IBP (n=39), while those who received ICI treatment for less than 6 weeks or discontinued it due to PD were defined as non-IBP (n=86). Patient clinical characteristics were evaluated. An optimization-based method was applied to balance the clinical baseline characteristics between the two groups. Results In total population, the IBP group had longer overall survival (median OS, 26.6 vs. 9.5 months; HR, 0.40; 95% CI: 0.23–0.69; P<0.001) and progression-free survival (median PFS, 8.9 vs. 4.1 months; HR, 0.41; 95% CI: 0.26–0.65; P<0.001), compared with the non-IBP group. Despite no significant difference in objective response rate (ORR, 15.4% vs. 11.6%, P=0.560), disease control rate (DCR) was significantly higher in the IBP group (89.7% vs. 61.6%, P<0.001). After balancing baseline covariates, the IBP group also had longer OS (median: 26.6 vs. 10.7 months; HR, 0.40; 95% CI: 0.19–0.84; P=0.015) and PFS (median: 9.7 vs. 4.3 months; HR, 0.28; 95% CI: 0.15–0.51; P<0.001), with a benefit in either of patients previously treated with ICI monotherapy or in combination therapy and with non-response to the previously ICI. Conclusions IBP is associated with longer OS and PFS in patients with aNSCLC. Our findings may suggest new therapeutic options for patients with aNSCLC who experienced disease progression after initial immunotherapy.
Dietary sodium intake does not alter renal potassium handling and blood pressure in healthy young males

Abstract Background The effects of sodium (Na+) intakes on renal handling of potassium (K+) are insufficiently studied. Methods We assessed the effect of Na+ on renal K+ handling in 16 healthy males assigned to three 7-day periods on low salt diet [LSD, 3 g sodium chloride (NaCl)/day], normal salt diet (NSD, 6 g NaCl/day) and high salt diet (HSD, 15 g NaCl/day), with constant K+ intake. Contributions of distal NaCl co-transporter and epithelial Na+ channel in the collecting system on K+ and Na+ handling were assessed at steady state by acute response to 100 mg oral hydrochlorothiazide and with addition of 10 mg of amiloride to hydrochlorothiazide, respectively. Results Diurnal blood pressure slightly increased from 119.30 ± 7.95 mmHg under LSD to 123.00 ± 7.50 mmHg (P = 0.02) under HSD, while estimated glomerular filtration rate increased from 133.20 ± 34.68 mL/min under LSD to 187.00 ± 49.10 under HSD (P = 0.005). The 24-h K+ excretion remained stable on all Na+ intakes (66.28 ± 19.12 mmol/24 h under LSD; 55.91 ± 21.17 mmol/24 h under NSD; and 66.81 ± 20.72 under HSD, P = 0.9). The hydrochlorothiazide-induced natriuresis was the highest under HSD (30.22 ± 12.53 mmol/h) and the lowest under LSD (15.38 ± 8.94 mmol/h, P = 0.02). Hydrochlorothiazide increased kaliuresis and amiloride decreased kaliuresis similarly on all three diets. Conclusions Neither spontaneous nor diuretic-induced K+ excretion was influenced by Na+ intake in healthy male subjects. However, the respective contribution of the distal convoluted tubule and the collecting duct to renal Na+ handling was dependent on dietary Na+ intake.
Fabrication and surface modification of micro/nanoporous silicon

We have studied surface and structural properties of micro/nanoporous silicon, synthesized by electrochemical etching of p-type Si (100) with different etching conditions. SEM studies reveal tunable pore sizes from 200 nm to 1.5 μm for etching time 5 to 30 min, and the thickness of pore walls decreases upto 20 nm for 30 min etching. AFM investigations reveal increase in roughness of the porous structure with increase in etching time and saturate around 250 nm at higher etching time. X-ray diffractogram of porous Si surface for etching time 20 min shows the appearance of two peaks at 2θ = 69.13° and 69.33°. For 30 min etching time a broad peak is observed at 26 = 69.39°. The broadening may due to the size distributions of pore walls, and up ward shifts may due to relaxation of strain in the porous structure. FTIR investigations show the presence of Si-H bending in Si 3 -SiH groups at 624 cm -1 , Si-O stretching in O-Si-O in between 1056-1160 cm -1 . The bands at 2958, 2927, and 2856 cm -1 are related to C-H stretching of CH 3, CH 2, and CH groups, which probably come from residual of HF-dimethylformamide.
Outpatient Opioid Prescriptions are Associated With Future Substance Use Disorders and Overdose Following Adolescent Trauma

Objective: This study aims to determine if outpatient opioid prescriptions are associated with future SUD diagnoses and overdose in injured adolescents 5 years following hospital discharge. Summary of Background Data: Approximately, 1 in 8 adolescents are diagnosed with an SUD and 1 in 10 experience an overdose in the 5 years following injury. State laws have become more restrictive on opioid prescribing by acute care providers for treating pain, however, prescriptions from other outpatient providers are still often obtained. Methods: This was a retrospective cohort study of patients ages 12–18 admitted to 2 level I trauma centers. Demographic and clinical data contained in trauma registries were linked to a regional database containing 5 years of electronic health records and prescription data. Regression models assessed whether number of outpatient opioid prescription fills after discharge at different time points in recovery were associated with a new SUD diagnosis or overdose, while controlling for demographic and injury characteristics, and depression and posttraumatic stress disorder diagnoses. Results: We linked 669 patients (90.9%) from trauma registries to a regional health information exchange database. Each prescription opioid refill in the first 3 months after discharge increased the likelihood of new SUD diagnoses by 55% (odds ratio: 1.55, confidence interval: 1.04–2.32). Odds of overdose increased with ongoing opioid use over 2–4 years post-discharge (P = 0.016–0.025). Conclusions: Short-term outpatient opioid prescribing over the first few months of recovery had the largest effect on developing an SUD, while long-term prescription use over multiple years was associated with a future overdose.
Multiple paternity and the number of offspring: A model reveals two major groups of species

Parentage analyses via microsatellite markers have revealed multiple paternity within the broods of polytocous species of mammals, reptiles, amphibians, fishes and invertebrates. The widespread phenomenon of multiple paternity may have attending relationships with such evolutionary processes as sexual selection and kin selection. However, just how much multiple paternity should a species exhibit? We developed Bayesian null models of how multiple paternity relates to brood sizes. For each of 114 species with published data on brood sizes and numbers of sires, we compared our null model estimates to published frequencies of multiple paternity. The majority of species fell close to our null model, especially among fish and invertebrate species. Some species, however, had low probabilities of multiple paternity, far from the predictions of the null model, likely due to sexual selection and environmental constraints. We suggest a major division among species’ mating systems between those with close to random mating and high levels of multiple paternity, and those with constraints that produce low levels of multiple paternity.
Assessment of knowledge and attitude of allied healthcare professionals about COVID-19 across Saudi Arabia.

BACKGROUND The coronavirus disease (COVID-19) has shown a catastrophic effect on mankind. The allied healthcare professionals (AHPs) play a pivotal role against COVID-19. OBJECTIVES To appraise the knowledge and attitude about COVID-19 of AHPs working across Saudi Arabia. METHODS This cross-sectional study was conducted using Qualtrics software to gather data from all five regions of Saudi Arabia during the nationwide lockdown in April 2020. Complete responses of 195 AHPs were considered for analysis. The questionnaire consisted of 15 and 14 questions on knowledge and attitude, respectively. The overall scores of each domain were calculated and modified Bloom's criterion was applied to categorize them into a three-point ordinal scale. Statistical analysis was performed using Chi-square test along with multivariate logistic regression for significant parameters. RESULTS The AHPs displayed a moderate level of knowledge (58.2%) and a good level of attitude (80%). The AHPs were found to have a non-significant (P > 0.05) difference in the level of knowledge within age, gender, region, occupation, educational level, organizational setup and years of experience. The attitude of AHPs working in a private setup has shown a 2.8 times (P = 0.020) higher risk for having moderate/poor attitude compared to the AHPs working in a government organization. CONCLUSIONS AHPs displayed a moderate level of knowledge and good attitude towards COVID-19. Emphasis should be given to continuous professional development in order to enhance their knowledge. Furthermore, strategies should be developed in the private sector to positively reinforce the attitude of AHPs.
Analytical pyrolysis of a soil profile under Scots pine

The chemical properties of pine needle litter cause slow decomposition, which results in an accumulation of highly lignocellulosic material on the forest floor. Decomposition of organic matter is important for the nutrient turnover in pine forests on nutrient‐poor soils. We studied the biodegradation of needles in an organic layer focusing on the various stages of lignin degradation by fungi. Samples were obtained from pine needle litter and a stratified organic layer over nutrient‐poor sand under a 60‐year‐old Scots pine (Pinus sylvestris forest stand. Pyrolysis mass spectrometry (PyMS) and pyrolysis gas chromatography mass spectrometry (PyGCMS) were used to characterize the chemical composition of the needles and the soil. The pyrolysis data show that diterpenoid acids are a main component in fresh needles, but rapidly decrease in the organic layer of the soil, as a result of decomposition. The chemical composition of the soil profile is dominated by guaiacyl lignin and polysaccharides from needle litter. The hexose/pentose ratio increases with depth in the soil profile. The partial preservation of hexose polymers is the result of the preferential decomposition of pentose polymers by white‐rot fungi, and points to the input of microbially synthesized polysaccharides. Indications for the degradation of guaiacyl lignin are also found in the soil profile. Oxidative reactions by soil fungi result in a shortening of the side chain of the guaiacyl lignin derivatives and an increase of carbonyl and carboxyl groups. These degradational patterns of lignin in the soil profile under Scots pine are similar to those observed in lignin model compounds and wood lignin degraded by fungi under controlled laboratory conditions.
Modeling for PEFC MEAs Based on Reaction Rate on Pt Surface and Microstructures of Catalyst Layers

A polymer electrolyte fuel cell membrane electrode assembly (PEFC MEA) model that focuses on the structural and reaction parameters of catalyst layers has been developed. The reaction and structural parameters were modeled independently by considering the oxygen reduction reaction (ORR) activity in terms of current per unit active surface area of Pt [A cm–2-Pt]. The catalyst layer models were constructed based on an assumption of cylindrical secondary pore structure, which was verified by measuring the primary pore size using mercury porosimetry. We found that penetration of Nafion® electrolyte into the primary pores of Pt/C catalysts was restricted, and thus diffusion and reaction in primary pores became negligible. Moreover, the experimental results demonstrated that for the same catalyst, ORR activity remained almost constant, irrespective of the agglomerate size (i.e., 2.7 × 10–6 A cm–2-Pt at 60°C for Pt/C TEC10E50E in this study). This supported our idea that reaction parameters and structural parameters should be considered independently in PEFC modeling. The cell performance predicted with the developed model was satisfactorily accurate as compared to that obtained from experiments. As a result, the modeling developed in this study can be used to construct simple PEFC models that yield results with good accuracy and can be a useful tool for the development of PEFCs in future.
Off-Label Use of Multitarget Stool DNA Testing in Primary Care.

INTRODUCTION We evaluated the off-label use of multitarget stool DNA (mt-sDNA) testing in the primary care setting. METHODS We reviewed all mt-sDNA orders between July 1, 2018, and June 30, 2019, to determine the frequency of off-label mt-sDNA orders. RESULTS Nine hundred two patients with mt-sDNA orders were evaluated, of which 160/902 patients (17.7%) met at least 1 criterion for off-label mt-sDNA order. Increasing age was associated with off-label order (Odds Ratio [OR] 2.32 [95% CI, 1.86-2.89] for every 10-year increase in age, P < 0.0001). On multivariate analysis, increased age (OR 1.04 [1.02-1.06], P = 0.001) and need for diagnostic colonoscopy (OR 2.9 [1.01-8.34], P = 0.048) were associated with a positive mt-sDNA result. DISCUSSION Off-label mt-sDNA testing is common, and further efforts are needed to educate patients and providers on appropriate use of mt-sDNA for colorectal cancer screening.
A genome-wide screen reveals microRNAs in peripheral sensory neurons driving painful diabetic neuropathy.

ABSTRACT Diabetes is a leading cause of peripheral neuropathy (diabetic peripheral neuropathy, DPN), and uncontrolled long-lasting hyperglycemia leads to severe complications. A major proportion of diabetics develop excruciating pain with a variable course. Mechanisms leading to painful DPN are not completely understood and treatment options limited. We hypothesized that epigenetic modulation at the level of microRNA (miRNA) expression triggered by metabolic imbalance and nerve damage regulates the course of pain development. We used clinically relevant preclinical models, genome-wide screening, in silico analyses, cellular assays, miRNA fluorescent in situ hybridization, in vivo molecular manipulations, and behavioral analyses in the current study. We identified miRNAs and their targets that critically impact on nociceptive hypersensitivity in painful DPN. Our analyses identify miR-33 and miR-380 expressed in nociceptive neurons as critical denominators of diabetic pain and miR-124-1 as a mediator of physiological nociception. Our comprehensive analyses on the putative mRNA targets for miR-33 or miR-124-1 identified a set of mRNAs that are regulated after miR-33 or miR-124-1 overexpression in dorsal root ganglia in vivo. Our results shed light on the regulation of DPN pathophysiology and implicate specific miRNAs as novel therapeutic targets for treating painful DPN.
