AbstractObjectivesAlthough cardiovascular disease (CVD) risk has been shown to differ between occupations, few studies have specifically evaluated the distribution of known CVD risk factors across occupational groups. This study assessed CVD risk factors in a range of occupational groups in New Zealand, stratified by sex and ethnicity.MethodsTwo probability-based sample surveys of the general New Zealand adult population (2004–2006; n = 3003) and of the indigenous people of New Zealand (Māori; 2009–2010; n = 2107), for which occupational histories and lifestyle factors were collected, were linked with routinely collected health data. Smoking, body mass index, deprivation, diabetes, high blood pressure, and high cholesterol were dichotomized and compared between occupational groups using age-adjusted logistic regression.ResultsThe prevalence of all known CVD risk factors was greater in the Māori survey than the general population survey, and in males compared with females. In general for men and women in both surveys ‘Plant and machine operators and assemblers’ and ‘Elementary workers’ were more likely to experience traditional CVD risk factors, while ‘Professionals’ were less likely to experience these risk factors. ‘Clerks’ were more likely to have high blood pressure and male ‘Agricultural and fishery workers’ in the general survey were less likely to have high cholesterol, but this was not observed in the Māori survey. Male Māori ‘Trades workers’ were less likely to have high cholesterol and were less obese, while for the general population survey, this was not observed.ConclusionsThis study showed differences in the distribution of known CVD risk factors across occupational groups, as well as between ethnic groups and males and females.

Abstract

Background
Influenza antigens may undergo adaptive mutations during egg-based vaccine production. In the 2017–2018 influenza season, quadrivalent, inactivated cell-derived influenza vaccine (ccIIV4) vaccine was produced using A(H3N2) seed virus propagated exclusively in cell culture, thus lacking egg adaptive changes. This United States study estimated relative vaccine effectiveness (rVE) of ccIIV4 vs egg-derived quadrivalent vaccines (egg-derived IIV4) for that season.

Methods
Vaccination, outcome, and covariate data were ascertained retrospectively from a electronic medical record (EMR) dataset and analyzed. The study cohort included patients ≥ 4 years of age. rVE was estimated against influenza-like illness (ILI) using diagnostic International Classification of Diseases, Ninth or Tenth Revision codes. The adjusted odds ratios used to derive rVE estimates were estimated from multivariable logistic regression models adjusted for age, sex, race/ethnicity, geographic region, and health status.

Results
Overall, 92 187 individuals had a primary care EMR record of ccIIV4 and 1 261 675 had a record of egg-derived IIV4. In the ccIIV4 group, 1705 narrowly defined ILI events occurred, and 25 645 occurred in the standard egg-derived IIV4 group. Crude rVE was 9.2% (95% confidence interval [CI], 4.6%–13.6%). When adjusted for age, sex, health status, comorbidities, and geographic region, the estimated rVE changed to 36.2% (95% CI, 26.1%–44.9%).

Conclusions
ccIIV4, derived from A(H3N2) seed virus propagated exclusively in cell culture, was more effective than egg-derived IIV4 in preventing ILI during the 2017–2018 influenza season. This result suggests that cell-derived influenza vaccines may have greater effectiveness than standard egg-derived vaccines.
Short-Term Dispersal and Long-Term Spatial and Temporal Patterns of Carabidae (Coleoptera) in Lowbush Blueberry Fields

Published: April 2020

AbstractCarabidae (Coleoptera) are important natural enemies of many insect pests in various cropping systems. Their population dynamics and how they disperse determine how effective they are at carrying out the natural enemy function. There are robust patterns of community dynamics in annual cropping systems, but it is unclear if these would carry over into a relatively underexplored North American perennial crop. In Nova Scotia lowbush blueberry fields, we found that Carabidae diversity did not change with distance from field edge nor with time. Their activity density also did not change with time, but it did change with distance from field edge. We also found that the most abundant carabid of lowbush blueberry, Harpalus rufipes (De Geer) (Coleoptera: Carabidae), can disperse approximately 14.5 m/d. Our results shed more light on the community dynamics of Carabidae in lowbush blueberry fields and can help growers make informed decisions when it comes to incorporating natural enemies into their pest management practices.

Abstract

Aims
Intensive and repetitive athletic training may result in cardiac geometric changes, but the determinants of left atrial (LA) enlargement (LAE) has been poorly studied. We investigated incidence and determinants of LAE and its association with LA strains in highly trained university athletes.

Methods and results
A total of 1073 athletes (451 females, 22.4 ± 2.4 years old) who were able to measure LA size, volume, and strains during 2015 Gwangju Summer Universiade were enrolled. LAE was defined as the increased LA volume index &gt; 42 mL/m2. LA strains, reservoir, conduit, and contractile were measured by 2D speckle tracking method, and LA reservoir strain &lt; 27.6% was considered as abnormal. LAE was developed in 205 athletes (19.1%). In univariate analysis, male [odds ratio (OR) = 1.679], Caucasian (OR = 1.746), non-African descent (OR = 1.804), body muscle mass (OR = 1.056), body fat mass (OR = 0.962), systolic blood pressure (OR = 1.012), heart rate (OR = 0.980), sports type with cardiovascular (CV) demand (OR = 1.474), training time (OR = 1.011), left ventricular (LV) global longitudinal strain (LVGLS, OR = 0.906), and LV stroke volume (LVSV, OR = 1.044) were significantly associated with LAE. In multivariate logistic regression analysis, heart rate (OR = 0.961) and sports type with CV demand (OR = 1.299), LVGLS (OR = 0.865) and LVSV (OR = 1.013) were independent determinants of LAE. Abnormal LA reservoir strain was noted in 56 athletes (5.2%), and the incidence of abnormal value was not different between two groups; 42 athletes (4.8%) in LAE vs. 14 (6.8%) in no LAE group (P = 0.293).

Conclusion
LAE was common in university athletes (19.1%) and associated with heart rate, sports type with CV demand, LVGLS, and LVSV. Although LAE was significantly associated with the lower LA reservoir strain, the incidence of abnormal value was very low (5.2%) and indifferent between LAE and no LAE group.

Abstract

Background
Sarcopenia is often conceptualized as a precursor to loss of mobility, but its effect on recovery of mobility after a hip fracture is unknown. We determined the prevalence of low muscle strength (weakness) after hip fracture using putative sarcopenia metrics (absolute grip strength, and grip strength normalized to body mass index, total body fat, arm lean mass, and weight) identified by the Sarcopenia Definitions and Outcomes Consortium (SDOC).

Methods
We examined two well-characterized hip fracture cohorts of community-dwelling older adults from the Baltimore Hip Studies (BHS). The prevalence of muscle weakness was assessed using the SDOC cut points compared to published definitions at 2 and 6 months postfracture. We assessed associations of 2-month weakness with 6-month walking speed &lt;0.6 m/s and calculated the sensitivity and specificity in predicting lack of meaningful change in walking speed (change &lt; 0.1 m/s) at 6 months.

Results
Two hundred and forty-six participants (192 women; 54 men) were included; mean (SD) age of 81 (8) for women and 78 (7) for men. At 2 months, 91% women and 78% men exhibited slow walking speed (&lt; 0.6 m/s). SDOC grip strength standardized by weight (&lt;0.34 kg women, &lt;0.45 kg men) was the most prevalent measure of weakness in men (74%) and women (79%) and provided high sensitivity in men (86%) and women (84%) predicting lack of meaningful change in walking speed at 6 months, although specificity was poor to moderate.

Conclusions
SDOC cut points for grip strength standardized to weight provided consistent indication of poor walking speed performance post-hip fracture.

Abstract
N-glycanase 1 (NGLY1) deficiency, an autosomal recessive disease caused by mutations in the NGLY1 gene, is characterized by developmental delay, hypolacrima or alacrima, seizure, intellectual disability, movement disorders and other neurological phenotypes. Because of few animal models that recapitulate these clinical signatures, the mechanisms of the onset of the disease and its progression are poorly understood, and the development of therapies is hindered. In this study, we generated the systemic Ngly1-deficient rodent model, Ngly1−/− rats, which showed developmental delay, movement disorder, somatosensory impairment and scoliosis. These phenotypes in Ngly1−/− rats are consistent with symptoms in human patients. In accordance with the pivotal role played by NGLY1 in endoplasmic reticulum-associated degradation processes, cleaving N-glycans from misfolded glycoproteins in the cytosol before they can be degraded by the proteasome, loss of Ngly1 led to accumulation of cytoplasmic ubiquitinated proteins, a marker of misfolded proteins in the neurons of the central nervous system of Ngly1−/− rats. Histological analysis identified prominent pathological abnormalities, including necrotic lesions, mineralization, intra- and extracellular eosinophilic bodies, astrogliosis, microgliosis and significant loss of mature neurons in the thalamic lateral and the medial parts of the ventral posterior nucleus and ventral lateral nucleus of Ngly1−/− rats. Axonal degradation in the sciatic nerves was also observed, as in human subjects. Ngly1−/− rats, which mimic the symptoms of human patients, will be a useful animal model for preclinical testing of therapeutic options and understanding the detailed mechanisms of NGLY1 deficiency.

Abstract
This study introduces a novel monoclonal anti-α9 integrin antibody (MA9-413) with human variable regions, isolated by phage display technology. MA9-413 specifically binds to both human and mouse α9 integrin by recognizing a conserved loop region designated as L1 (amino acids 104–122 of human α9 integrin). MA9-413 inhibits human and mouse α9 integrin-dependent cell adhesion to ligands and suppresses synovial inflammation and osteoclast activation in a mouse model of arthritis. This is the first monoclonal anti-α9 integrin antibody that can react with and functionally inhibit both human and mouse α9 integrin. MA9-413 allows data acquisition both in animal and human pharmacological studies without resorting to surrogate antibodies. Since MA9-413 showed certain therapeutic effects in the mouse arthritis model, it can be considered as a useful therapy against rheumatoid arthritis and other α9 integrin-associated diseases.
The Identity of Psychiatry and the Challenge of Mad Activism: Rethinking the Clinical Encounter
Authors: Rashed Mohammed Abouelleil 
Published: April 2020

AbstractCentral to the identity of modern medical specialities, including psychiatry, is the notion of hypostatic abstraction: doctors treat conditions or disorders, which are conceived of as “things” that people “have.” Mad activism rejects this notion and hence challenges psychiatry’s identity as a medical specialty. This article elaborates the challenge of Mad activism and develops the hypostatic abstraction as applied to medicine. For psychiatry to maintain its identity as a medical speciality while accommodating the challenge of Mad activism, it must develop an additional conception of the clinical encounter. Toward elaborating this conception, this article raises two basic framing questions: For what kind of understanding of the situation should the clinical encounter aim? What is the therapeutic aim of the encounter as a whole? It proposes that the concepts of “secondary insight” (as the aim of understanding) and of “identity-making” (as a therapeutic aim) can allow the clinical encounter to proceed in a way that accommodates the challenge of Mad activism.

AbstractUnderstanding the genetic basis of similar phenotypes shared between lineages is a long-lasting research interest. Even though animal evolution offers many examples of parallelism, for many phenotypes little is known about the underlying genes and mutations. We here use a combination of whole-genome sequencing, expression analyses, and comparative genomics to study the parallel genetic origin of ptilopody (Pti) in chicken. Ptilopody (or foot feathering) is a polygenic trait that can be observed in domesticated and wild avian species and is characterized by the partial or complete development of feathers on the ankle and feet. In domesticated birds, ptilopody is easily selected to fixation, though extensive variation in the type and level of feather development is often observed. By means of a genome-wide association analysis, we identified two genomic regions associated with ptilopody. At one of the loci, we identified a 17-kb deletion affecting PITX1 expression, a gene known to encode a transcription regulator of hindlimb identity and development. Similarly to pigeon, at the second loci, we observed ectopic expression of TBX5, a gene involved in forelimb identity and a key determinant of foot feather development. We also observed that the trait evolved only once as foot-feathered birds share the same haplotype upstream TBX5. Our findings indicate that in chicken and pigeon ptilopody is determined by the same set of genes that affect similar molecular pathways. Our study confirms that ptilopody has evolved through parallel evolution in chicken and pigeon.

AbstractBackgroundHepatitis C virus (HCV) coinfection among people with human immunodeficiency virus (HIV) might perturb immune function and HIV persistence. We aimed to evaluate the impact of HCV clearance with direct-acting antivirals (DAAs) on immune activation and HIV persistence in HIV/HCV-coinfected individuals on antiretroviral therapy (ART).MethodsIn a prospective observational study, ART-treated participants with HIV/HCV coinfection received sofosbuvir/daclatasvir ± ribavirin (n = 19). Blood samples were collected before DAA therapy, at the end of treatment, and 12 months after DAA termination (12MPT). T- and natural killer (NK)-cell phenotype, soluble plasma factors, cell-associated (CA)-HIV deoxyribonucleic acid (DNA) forms (total, integrated, 2LTR), CA-unspliced (US) and multiple-spliced ribonucleic acid (RNA), and plasma HIV RNA were evaluated.ResultsHepatitis C virus clearance was associated with (1) a downmodulation of activation and exhaustion markers in CD4+, CD8+ T, and NK cells together with (2) decreased plasma levels of Interferon gamma-induced protein 10 (IP10), interleukin-8 (IL-8), soluble (s)CD163 and soluble intercellular adhesion molecule (sICAM). Cell-associated US HIV RNA was significantly higher at 12MPT compared to baseline, with no change in HIV DNA or plasma RNA.ConclusionsElimination of HCV in HIV/HCV-coinfected individuals alters immune function and the transcriptional activity of latently infected cells. This report provides insights into the effects of HCV coinfection in HIV persistence and regards coinfected subjects as a population in which HIV remission might prove to be more challenging.

Published: April 2020

Abstract

Background
Hydatid disease is a severe health problem in endemic areas. In recent years, the incidence of this disease in China has been increasing. As the imaging characteristics of pancreatic echinococcosis (PE) are similar to those of cystic diseases, such as cysts, tuberculosis, and tumors, PE is often misdiagnosed and mistreated.

Methods
The clinical manifestations, laboratory tests, radiological findings, and treatment of 19 patients with PE between January 2006 and December 2018 in 2 hospitals were retrospectively analyzed.

Results
The mean age of the patients was 38 years, and the ratio of women to men was 2. All patients came from rural areas. Clinical manifestations included cholestatic jaundice, mass, nausea, pain, and swelling. Hemagglutination inhibition test results were positive for all patients. Enzyme-linked immunosorbent assay test results were positive in 17 cases (89.5%). Foci in the pancreas were head in 52.6%, body in 26.3%, body and tail in 15.8%, tail in 5.3%. The size of lesions’ diameter ranged from 1 to 12 cm (mean, 6.5 cm). The imaging features of PE included the presence of (a) daughter cysts on abdominal computed tomography (CT) and/or magnetic resonance imaging (MRI); (b) internal cyst wall dissection and ribbon sign on abdominal CT and/or MRI; (c) typical eggshell cyst wall calcification on abdominal CT.

Conclusions
For patients with cystic lesions on CT and/or MRI combined with epidemiological history and positive echinococcosis serology, doctors can correctly diagnose PE earlier. Surgical treatment combined with drugs can reduce the mortality of PE, leading to a better prognosis.
ASYMPTOTICS OF ENTIRE FUNCTIONS AND A PROBLEM OF HAYMAN
Authors: Hilberdink Titus 
Published: April 2020

AbstractIn this paper, we study entire functions whose maximum on a disc of radius $r$ grows like $e^{h(\log r)}$ for some function $h(\cdot )$. We show that this is impossible if $h^{\prime \prime }(r)$ tends to a limit as $r\to \infty $, thereby solving a problem of Hayman from 1966. On the other hand, we show that entire functions can, under some mild smoothness conditions, grow like $\textrm{e}^{h(\log r)}$ if $h^{\prime \prime }(r)\to \infty $.

ABSTRACTHigh density single nucleotide polymorphism (SNP) arrays allow large numbers of individuals to be rapidly and cost-effectively genotyped at large numbers of genetic markers. However, despite being widely used in studies of humans and domesticated plants and animals, SNP arrays are lacking for most wild organisms. We developed a custom 90K Affymetrix Axiom array for an intensively studied pinniped, the Antarctic fur seal (Arctocephalus gazella). SNPs were discovered from a combination of genomic and transcriptomic resources and filtered according to strict criteria. Out of a total of 85,359 SNPs tiled on the array, 75,601 (88.6%) successfully converted and were polymorphic in 274 animals from a breeding colony at Bird Island in South Georgia. Evidence was found for inbreeding, with three genomic inbreeding coefficients being strongly intercorrelated and the proportion of the genome in ROH being non-zero in all individuals. Furthermore, analysis of genomic relatedness coefficients identified multiple second and third order relatives among a sample of ostensibly unrelated individuals. Such “cryptic relatedness” within fur seal breeding colonies may increase the likelihood of consanguinous matings and could therefore have implications for understanding fitness variation and mate choice. Finally, we demonstrate the cross-amplification potential of the array in three related species. Overall, our SNP array will facilitate future studies of Antarctic fur seals and has the potential to serve as a more general resource for the wider pinniped research community.

ABSTRACTCancer cells acquire resistance to cytotoxic therapies targeting major survival pathways by adapting their metabolism. The AKT pathway is a major regulator of human pancreatic adenocarcinoma progression. The mechanisms of adaptation to long-term silencing of AKT isoforms of pancreatic cancer cells were studied. Following silencing, cancer cells remained quiescent for long periods of time, after which they recovered proliferative capacities. Adaptation caused profound proteomic changes largely affecting mitochondrial biogenesis, energy metabolism, and acquisition of a number of distinct cancer stem cell (CSC) characteristics depending on the AKT isoform that was silenced. The adaptation to AKT1 silencing drove most de-differentiation and acquisition of stemness through C-MYC down-modulation and NANOG up-regulation, which were required for survival of adapted CSCs. The changes associated to adaptation sensitized cancer cells to inhibitors targeting regulators of oxidative respiration and mitochondrial biogenesis.In vivopharmacological co-inhibition of AKT and mitochondrial metabolism effectively controlled pancreatic adenocarcinoma growth in pre-clinical models.
