Anxiety during abstinence from alcohol: A systematic review of rodent and human evidence for the anterior insula's role in the abstinence network

Alcohol Use Disorder (AUD) is a chronic, relapsing disease that impacts almost a third of Americans. Despite effective treatments for attaining sobriety, the majority of patients relapse within a year, making relapse a substantial barrier to long‐term treatment success. A major factor contributing to relapse is heightened negative affect that results from the combination of abstinence‐related increases in stress‐reactivity and decreases in reward sensitivity. Substantial research has contributed to the understanding of reward‐related changes in AUD. However, less is known about anxiety during abstinence, a critical component of understanding addiction as anxiety during abstinence can trigger relapse. Most of what we know about abstinence‐related negative affect comes from rodent studies which have identified key brain regions responsible for abstinence‐related behaviors. This abstinence network is composed of brain regions that make up the extended amygdala: the nucleus accumbens (NAcc), the central nucleus of the amygdala (CeA), and the bed nucleus of the stria terminalis (BNST). More recently, emerging evidence from rodent and human studies suggests a fourth brain region, the anterior insula, might be part of the abstinence network. Here, we review current rodent and human literature on the extended amygdala's role in alcohol abstinence and anxiety, present evidence for the anterior insula's role in the abstinence network, and provide future directions for research to further elucidate the neural underpinnings of abstinence in humans. A better understanding of the abstinence network is critical toward understanding and possibly preventing relapse in AUD.
Quantitative diffusion-weighted magnetic resonance imaging for prediction of early infection in pancreatic collections: Results of a pilot study

Background/Aims: The development of infection in pancreatitis increases the mortality rate up to 32%. Therefore, it is important to identify patients who are at high risk of developing infection, at an early stage. The objectives of the study were (a) to analyze the quantitative parameters of diffusion-weighted magnetic resonance imaging (DW-MRI) and apparent diffusion coefficient (ADC) in infected as well as sterile pancreatic collections (b) to establish “cut-off” values for ADC that can identify infected pancreatic collections. Materials and Methods: Prospective observational study of pancreatitis cases who underwent DW-MRI from August 2018 to July 2019 were enrolled in the study. The collections were analyzed for diffusion restriction. The average of the three ADC values from the wall and center of collection was noted. Results: Infected collections were seen in 7 and sterile collections observed in 11 cases. The optimal cut-off ADC value to differentiate sterile and infected collection in our study was 1.651 × 10-3 mm2/s (sensitivity of 81.8%; specificity of 100.0%). ROC curve for mean ADC from the wall showed a significant diagnostic accuracy with AUC: 0.91; 95% CI: 0.77-1.0 (P = 0.004). Conclusion: DW-MRI is a reliable noninvasive technique to differentiate sterile and infected pancreatic collections. ADC values from the periphery of the collection can predict infected pancreatic collections at an early stage. DW-MRI should not be considered as a substitute for aspiration cytology in patients with septic symptoms and absent diffusion restriction on MRI.
Morpholino Target Molecular Properties Affect the Swelling Process of Oligomorpholino-Functionalized Responsive Hydrogels

Responsive hydrogels featuring DNA as a functional unit are attracting increasing interest due to combination of versatility and numerous applications. The possibility to use nucleic acid analogues opens for further customization of the hydrogels. In the present work, the commonly employed DNA oligonucleotides in DNA-co-acrylamide responsive hydrogels are replaced by Morpholino oligonucleotides. The uncharged backbone of this nucleic acid analogue makes it less susceptible to possible enzymatic degradation. In this work we address fundamental issues related to key processes in the hydrogel response; such as partitioning of the free oligonucleotides and the strand displacement process. The hydrogels were prepared at the end of optical fibers for interferometric size monitoring and imaged using confocal laser scanning microscopy of the fluorescently labeled free oligonucleotides to observe their apparent diffusion and accumulation within the hydrogels. Morpholino-based hydrogels’ response to Morpholino targets was compared to DNA hydrogels’ response to DNA targets of the same base-pair sequence. Non-binding targets were observed to be less depleted in Morpholino hydrogels than in DNA hydrogels, due to their electroneutrality, resulting in faster kinetics for Morpholinos. The electroneutrality, however, also led to the total swelling response of the Morpholino hydrogels being smaller than that of DNA, since their lack of charges eliminates swelling resulting from the influx of counter-ions upon oligonucleotide binding. We have shown that employing nucleic acid analogues instead of DNA in hydrogels has a profound effect on the hydrogel response.
Glucose absorption from peritoneal dialysate is associated with a gain in fat mass and a reduction in lean body mass in prevalent peritoneal dialysis patients.

The majority of peritoneal dialysates use glucose to generate an osmotic gradient for the convective removal of water and sodium. Although glucose can potentially be absorbed, previous studies have failed to establish whether this leads to increased fat weight gain. We measured body composition using bioimpedance in peritoneal dialysis (PD) patients, electively starting PD, attending for their first assessment of peritoneal membrane function after 2-3 months, and then after 12 months. We studied 143 patients; 89 (62.2%) males, 53 (37.1%) diabetics, mean age 61.3±14.9 years, with 90 (62.1%) of patients treated by automated PD cyclers (APD) with a daytime icodextrin exchange and 37 (25.9%) by continuous ambulatory PD (CAPD). Median fat mass increased by 1.8 (-0.5 to 4.1) kg, whereas fat free mass fell -1.3 (-2.9 to 1.0) kg, and the increase in fat mass was negatively associated with the fall in soft lean mass (r-0.41, p<0.001). Increased fat mass was associated with measured peritoneal glucose absorption (r=0.69, p<0.001), and glucose absorption was associated with the amount of 22.7 g/L glucose dialysate (odds ratio (OR) 2.0, 95% confidence limits (CL) 1.5-2.5, p<0.001), peritoneal urea clearance (OR 9.5 (CL 2.4-37.1) p=0.001), and male gender (OR 4.8 (CL 1.5-14.9) p=0.008). We report an observational study in prevalent PD patients following body composition from their first assessment of peritoneal dialysis membrane function for approximately 12 months, and despite the majority of patients prescribed icodextrin, we have demonstrated an association between intra-peritoneal glucose absorption and fat weight gain, but also loss of fat-free mass.
A Detailed Biological and Chemical Investigation of Sixteen Achillea Species’ Essential Oils via Chemometric Approach

Representatives of the Achillea genus are widely used as foods or nutraceuticals. Considering the increasing demand for herbal dietary supplements with health promoting effects, the objective of this research was to evaluate the chemical composition and biological activities of the essential oils obtained from sixteen Achillea species (A. biebersteinii, A. wilhelmsii subsp. wilhelmsii, A. aleppica subsp. zederbaueri, A. vermicularis, A. monocephala, A. nobilis, A. goniocephala, A. sintenisii, A. coarctata, A. kotschyi subsp. kotschyi, A. millefolium subsp. millefolium, A. lycaonica, A. spinulifolia, A. teretifolia, A. setacea, and A. schischkinii). Anticholinesterase, antiurease, antityrosinase enzymes inhibition, antioxidant, antimicrobial, toxic and cytotoxic activities of obtained essential oils were investigated. DPPH activities were found to be very low in all studied samples, while ABTS and CUPRAC antioxidant activities were found to be moderate. In addition, all samples were found to have moderate anticholinesterase and antimicrobial effects. It has been determined that the studied species have low cytotoxicity and high toxicity. Besides, chemical composition of the essential oils were determined by GC/MS and the results were chemometrically analyzed. The chemometric analyses of Achillea species collected from nine different regions were accomplished by principal component analysis (PCA) and hierarchical cluster analysis (HCA) techniques. According to the PCA analysis, A. nobilis subsp. neilreichii was found to be different from all studied species in terms of essential oil composition. The major components found in these species were piperitone, camphor, α‐terpinene, eucalyptol, artemisia ketone, endo‐borneol, β‐eudesmol and verbenol. The fact that camphor was toxic and found in majority of the studied species stands out as a remarkable result.
Stringent Selection of Knobby Plasmodium falciparum-Infected Erythrocytes during Cytoadhesion at Febrile Temperature

Changes in the erythrocyte membrane induced by Plasmodium falciparum invasion allow cytoadhesion of infected erythrocytes (IEs) to the host endothelium, which can lead to severe complications. Binding to endothelial cell receptors (ECRs) is mainly mediated by members of the P. falciparum erythrocyte membrane protein 1 (PfEMP1) family, encoded by var genes. Malaria infection causes several common symptoms, with fever being the most apparent. In this study, the effects of febrile conditions on cytoadhesion of predominately knobless erythrocytes infected with the laboratory isolate IT4 to chondroitin-4-sulfate A (CSA), intercellular adhesion molecule 1 (ICAM-1), and CD36 were investigated. IEs enriched for binding to CSA at 40 °C exhibited significantly increased binding capacity relative to parasites enriched at 37 °C. This interaction was due to increased var2csa expression and trafficking of the corresponding PfEMP1 to the IE surface as well as to a selection of knobby IEs. Furthermore, the enrichment of IEs to ICAM-1 at 40 °C also led to selection of knobby IEs over knobless IEs, whereas enrichment on CD36 did not lead to a selection. In summary, these findings demonstrate that knobs are crucial for parasitic survival in the host, especially during fever episodes, and thus, that selection pressure on the formation of knobs could be controlled by the host.
SV40 Large T Antigen Is Not Responsible for the Loss of STING in 293T Cells but Can Inhibit cGAS-STING Interferon Induction

Several DNA viruses have evolved antagonists to inhibit the cyclic GMP–AMP synthase (cGAS)-stimulator of interferon genes (STING) DNA-sensing immune pathway. This includes DNA viral oncogenes that antagonize the cGAS-STING pathway by binding STING through the LxCxE motif. The 293T human cells are widely used in biology studies as they are highly transfectable. While parental 293 cells express high levels of STING, 293T cells lack STING and are unable to induce interferon antiviral responses to cytosolic DNA. Additionally, 293T cells express the SV40 polyomavirus large T antigen (LT) which enhances the replication of transfected DNA plasmids carrying the SV40 origin of replication. Since SV40 LT also encodes the LxCxE motif, the lack of STING expression in 293T cells is commonly assumed to be due to SV40 large T antigen. We find that SV40 LT does not alter exogenously expressed and endogenous levels of STING protein. We show that STING transcription is suppressed in 293T cells but is not driven by SV40. This study also revealed that SV40 LT does indeed inhibit cGAS-STING interferon induction, but through a mechanism distinct from other DNA virus oncogenes. Collectively, these results indicate that while SV40 LT can inhibit cGAS-STING interferon induction, it does so in an unanticipated manner.
Validation of the Lithuanian version of the Eating Disorder Examination Questionnaire 6.0 in a student sample

The Eating Disorder Examination Questionnaire 6.0 (EDE‐Q 6.0) is one of the most broadly used self‐report tools that assesses attitudes and behaviors associated with eating disorders (EDs). The aim of the present study was to examine the reliability, validity, and factor structure of the Lithuanian version of the EDE‐Q 6.0 (LT‐EDE‐Q 6.0) in a nonclinical student sample.
Effects of a campus-wide tobacco-free policy on tobacco attitudes, norms and behaviors among students, staff and faculty

Abstract Objective: In 2016 a private Missouri university implemented a campus-wide tobacco-free policy to change social norms and prevent tobacco use among students, staff and faculty. This study assesses impact on tobacco and policy-related perceptions and behaviors. Methods: Before the policy went into effect and again one year later, all university students, staff and faculty were invited to participate in an online survey. Missouri Assessment of College Health Behaviors survey findings supplement results for students. Results: Policy support and norms disapproving tobacco use on campus increased, and self-reported use of any tobacco decreased after the ban was enacted. Conclusions: Our results suggest that the policy led to an increase in the proportion of university community members who agree that smoking on campus is unacceptable, which contributed in turn to a decline in tobacco use on campus, consistent with our theory of effects.

Nutritional status and follicular-derived thyroid cancer: An update

Abstract The incidence of differentiated thyroid cancer has been increasing in the last decades all over the world. Such a steady growth cannot be entirely attributable to more intensive thyroid nodule screening and more sensitive diagnostic procedures. Several environmental factors have changed with sufficient rapidity in the same time frame and may represent credible candidates for this increase. They include modified iodine intake, lifestyle-associated risk factors, exposure to various toxic compounds, pollutants and xenobiotics, nutritional deficiencies, eating habits and comorbidities. Foremost, nutritional patterns have gained high interest as possible promoters and modifiable risk factors for thyroid cancer in recent years. The aim of this narrative review is to focus on the relationship between thyroid cancer and nutritional factors, dietary habits and obesity. Low iodine intake has been associated to increased risk of thyroid cancer, favoring the development of more aggressive histotypes. Moreover, correction of iodine deficiency can shift thyroid cancer subtypes toward less aggressive forms, without affecting the overall risk for cancer. Actually, evidence regarding the association between selenium and vitamin D deficiency and thyroid cancer is very limited, despite their well-known anti-cancer potentials, and the clinical usefulness of their supplementation is still uncertain in this setting. Albeit the relationship between single foods and thyroid cancer is difficult to examine, fish and iodine-rich foods, vegetables, and fruits might exert protective effects on thyroid cancer risk. Conversely, no clear association has been found for other foods to date. Lastly, a clear association between obesity and the risk of thyroid cancer, with more aggressive behavior, seems to emerge from most studies, likely involving variations in thyroid function and chronic inflammation mediated by cytokines, insulin, leptin and adiponectins. Although no definite association between dietary factors and thyroid cancer has been firmly established so far, some nutritional patterns, together with excessive weight, seem to play a relevant role in thyroid cancer carcinogenesis as well as in its severity and aggressiveness. These effects may play an additive role to the well-established one exerted by environmental carcinogens, such as pollutants and radiation exposure.
The 2019‐new coronavirus epidemic: Evidence for virus evolution

There is concern about a new coronavirus, the 2019-nCoV, as a global public health threat. In this article, we provide a preliminary evolutionary and molecular epidemiological analysis of this new virus. A phylogenetic tree has been built using the 15 available whole genome sequence of 2019-nCoV and 12 whole genome sequences highly similar sequences available in gene bank (5 from SARS, 2 from MERS and 5 from Bat SARS-like Coronavirus). FUBAR analysis shows that the Nucleocapsid and the Spike Glycoprotein has some sites under positive pressure while homology modelling helped to explain some molecular and structural differences between the viruses. The phylogenetic tree showed that 2019.nCoV significantly clustered with Bat SARS-like Coronavirus sequence isolated in 2015, whereas structural analysis revealed mutation in S and nucleocapsid proteins. From these results, 2019nCoV could be considered a coronavirus distinct from SARS virus, probably transmitted from bats or another host where mutations conferred upon it the ability to infect humans.
Targets of biologic disease‐modifying antirheumatic drugs and risk of multiple myeloma

Several commonly used immune‐suppressing biologic drugs target proteins and cytokines involved in myeloma pathogenesis. Our objective was to determine whether targeted biologic disease‐modifying antirheumatic drugs (DMARDs) are associated with risk of multiple myeloma (MM). We conducted a nested case–control study within a retrospective cohort of 56,886 commercially insured adults undergoing treatment for rheumatoid arthritis, psoriatic arthritis or ankylosing spondylitis between 2009 and 2015 using the Truven Health MarketScan Databases. MM cases (n = 287) were matched to up to 10 controls (n = 2,760) on age, sex and rheumatologic indication using incidence density sampling without replacement. Our exposures of interest were biologic DMARDs targeting tumor necrosis factor‐alpha, interleukin 6, cytotoxic t‐lymphocyte‐associated protein‐4 and depletion of B cells. Relative risks were estimated as adjusted odds ratios (OR) and 95% confidence intervals (CI) using conditional logistic regression models. Cases and controls were similar with respect to use of prescription NSAIDs and concurrent conventional‐synthetic DMARDs. Cases had slightly fewer etanercept users (4% vs. 7%) and slightly more tocilizumab users (1.4% vs. 0.4%). Compared to patients treated with only conventional‐synthetic DMARDs, those receiving concomitant conventional‐synthetic plus biologic DMARDs had lower risk of developing MM (OR = 0.48; 95% CI 0.30–0.88; p = 0.02). Risks differed by drug target with an inverse association observed with use of etanercept inhibiting tumor necrosis factor‐alpha (OR = 0.55; 95% CI 0.30–1.02; p = 0.06) and a positive association with tocilizumab inhibiting interleukin‐6 (OR = 4.33; 95% CI 1.33–14.19; p = 0.02) compared to biologic DMARD‐naïve patients. Further investigation is warranted to understand the roles of drugs suppressing tumor necrosis factor‐alpha and interleukin‐6 in myeloma pathogenesis.
Modeling of the Concentrations of Ultrafine Particles in the Plumes of Ships in the Vicinity of Major Harbors

Marine traffic in harbors can be responsible for significant atmospheric concentrations of ultrafine particles (UFPs), which have widely recognized negative effects on human health. It is therefore essential to model and measure the time evolution of the number size distributions and chemical composition of UFPs in ship exhaust to assess the resulting exposure in the vicinity of shipping routes. In this study, a sequential modelling chain was developed and applied, in combination with the data measured and collected in major harbor areas in the cities of Helsinki and Turku in Finland, during winter and summer in 2010–2011. The models described ship emissions, atmospheric dispersion, and aerosol dynamics, complemented with a time–microenvironment–activity model to estimate the short-term UFP exposure. We estimated the dilution ratio during the initial fast expansion of the exhaust plume to be approximately equal to eight. This dispersion regime resulted in a fully formed nucleation mode (denoted as Nuc2). Different selected modelling assumptions about the chemical composition of Nuc2 did not have an effect on the formation of nucleation mode particles. Aerosol model simulations of the dispersing ship plume also revealed a partially formed nucleation mode (Nuc1; peaking at 1.5 nm), consisting of freshly nucleated sulfate particles and condensed organics that were produced within the first few seconds. However, subsequent growth of the new particles was limited, due to efficient scavenging by the larger particles originating from the ship exhaust. The transport of UFPs downwind of the ship track increased the hourly mean UFP concentrations in the neighboring residential areas by a factor of two or more up to a distance of 3600 m, compared with the corresponding UFP concentrations in the urban background. The substantially increased UFP concentrations due to ship traffic significantly affected the daily mean exposures in residential areas located in the vicinity of the harbors.
Rotavirus vaccination impact, Ireland, implications for vaccine confidence and screening.

BACKGROUND Rotavirus vaccine efficacy is well established. However, it is important to consistently demonstrate the positive impact of vaccination programmes in order to optimize uptake rates and combat vaccine hesitancy. METHODS Routine data were used to examine rotavirus vaccine effectiveness in Ireland, including changes in age-specific crude incidence rates (CIRs), hospitalizations and hospital length of stay. National intussusception incidence was interrogated. Vaccination status of vaccine-eligible cases of rotavirus infection was determined. RESULTS Nationally, a reduction in the CIR of rotavirus infection of 77.2% [95% confidence interval (CI) 57.8-88.5%, P<0.001] was observed post-inclusion of the rotavirus vaccine in the primary immunization schedule. A decrease in hospitalizations of 85.5% (95% CI 79.3-90.2%, P<0.001), 86.5% (95% CI 82.9-89.4%, P<0.001) and 78.5% (95% CI 74.7-81.9%, P<0.001) was observed in children aged <1, <2 and <5 years, respectively. Most hospitalizations occurred in infants too young to have been vaccinated. There was no significant difference in median length of stay for children hospitalized with rotavirus infection. Decreased CIRs and hospitalization rates in unvaccinated children aged between 2 and 5 years suggest community immunity. Vaccine non-protection was 0.13%. No increase in the national CIR of intussusception was observed. CONCLUSIONS Inclusion of the rotavirus vaccine in the Irish primary immunization schedule has resulted in a significant reduction in the burden of rotavirus infection. However, vaccine hesitancy remains a concern. With new vaccination programmes, risk of vaccine harms should be considered and mitigated in order to protect individuals and the integrity of the programme.
