Consumer preferences for Nile tilapia (Oreochromis niloticus) value-added products in Samoa

Nile tilapia (Oreochromis niloticus) is an introduced low-value freshwater fish available in the Pacific that has limited scope for consumption in its fresh form. With increased fishing activity and climate change posing threats to global food security, utilisation of this cultured fish may aid in alleviating food security issues in the Pacific. This study explores the potential for better utilisation of Nile tilapia by developing four processed forms – salted-cold smoked, cured-cold smoked, surimi and fish paste – and evaluating these forms through consumer preference testing. A list of sensory terminology and a scoring system for fresh and cooked tilapia were developed prior to the testing. The consumer preference testing was conducted in the fish market, Apia, Samoa with a total of 71 consumers. Fish paste was the most preferred product, followed by salted-cold smoked, then surimi while cured-cold smoked tilapia was the least preferred. However, no significant difference (P ≥ 0.05) was observed between preference of these products, indicating the acceptability of all four products by Samoan consumers. This means that there is the potential for commercialising these products.
Pathogenic viruses in Finnish waters : occurrence, fate and control

Waterborne outbreaks occur worldwide, even though knowledge of the health risks posed by microbes in the environment is increasing. In Finland, between 3 and 11 waterborne outbreaks occur every year, and the number of patients may vary from a few to several thousand. Enteric viruses, especially noroviruses, are the main causative agents of waterborne outbreaks, and they end up in the environment mainly through wastewater discharge. The cause of the outbreak is usually connected to deficiencies in the management of water supply and sewerage systems, which results in human wastewater contamination of groundwater or recreational water. In this thesis, both laboratory and pilot-scale experiments as well as investigations performed during the waterborne outbreaks were utilised in order to study the occurrence, transport, persistence and control of enteric viruses (noroand adenoviruses). In addition, the aim was to study the feasibility of currently used feacal indicator microbes in assessing water quality. Enteric viruses showed high prevalence in wastewater. Norovirus GI, norovirus GII and adenoviruses were found in 94.7%, 100% and 100%, respectively, of 19 influent samples collected from municipal wastewater treatment plant (WWTP) during a one-year period. The stable occurrence of adenoviruses in wastewater throughout the year supports their use as markers of human wastewater pollution. Although noroviruses were also detected throughout the year in wastewater, their numbers varied, being highest in winter. High numbers of norovirus GII were detected in groundwater and tap water samples in two drinking water outbreaks (I and II) described in this study. In addition, adenovirus was detected in drinking water outbreak II. On the other hand, only 25% of the water samples collected during seven bathing water outbreaks were positive for noroand/or adenoviruses. This addresses the temporal and methodological challenges related to detecting contamination.
Factors Associated with Return to Work Following Myocardial Infarction: A Systematic Review of Observational Studies.

OBJECTIVES To identify and critically synthesise literature on return to work of patients following a myocardial infarction, and to identify factors that are associated with this. BACKGROUND Understanding when patients return to work after myocardial infarction and what factors are associated with this may be helpful in designing person-centred treatment plans to facilitate patients' rehabilitation and return to work. DESIGN A narrative systematic review. REVIEW METHODS Six databases, MEDLINE, CINAHL, Academic Search Complete, EMBASE, SCOPUS, and ProQuest Health and Medicine, and the search engine Google were searched to retrieve peer-reviewed articles published in English from January 2008 to January 2020. In total 22,217 papers were sourced and screened, with 18 papers retained for quality appraisal using the Joanna Briggs Institute Critical Appraisal Tools. RESULTS The mean time to return to work varied between 46 and 192 days; about half the participants resumed work by three months. Patients who were male, younger, educated, non-manual workers or owned their own business, and those who evaluated their general and mental health highly, had shorter hospitalisation, fewer comorbidities, complications and mental health issues, were more likely to return to work after myocardial infarction. CONCLUSION & RELEVANCE TO CLINICAL PRACTICE Findings may help nurses detect patients at increased risk of failure to return to work, and provide appropriate support to facilitate this.
Association between Brachyspira and irritable bowel syndrome with diarrhoea

Objective The incidence of IBS increases following enteric infections, suggesting a causative role for microbial imbalance. However, analyses of faecal microbiota have not demonstrated consistent alterations. Here, we used metaproteomics to investigate potential associations between mucus-resident microbiota and IBS symptoms. Design Mucus samples were prospectively collected from sigmoid colon biopsies from patients with IBS and healthy volunteers, and their microbial protein composition analysed by mass spectrometry. Observations were verified by immunofluorescence, electron microscopy and real-time PCR, further confirmed in a second cohort, and correlated with comprehensive profiling of clinical characteristics and mucosal immune responses. Results Metaproteomic analysis of colon mucus samples identified peptides from potentially pathogenic Brachyspira species in a subset of patients with IBS. Using multiple diagnostic methods, mucosal Brachyspira colonisation was detected in a total of 19/62 (31%) patients with IBS from two prospective cohorts, versus 0/31 healthy volunteers (p<0.001). The prevalence of Brachyspira colonisation in IBS with diarrhoea (IBS-D) was 40% in both cohorts (p=0.02 and p=0.006 vs controls). Brachyspira attachment to the colonocyte apical membrane was observed in 20% of patients with IBS and associated with accelerated oro-anal transit, mild mucosal inflammation, mast cell activation and alterations of molecular pathways linked to bacterial uptake and ion–fluid homeostasis. Metronidazole treatment paradoxically promoted Brachyspira relocation into goblet cell secretory granules—possibly representing a novel bacterial strategy to evade antibiotics. Conclusion Mucosal Brachyspira colonisation was significantly more common in IBS and associated with distinctive clinical, histological and molecular characteristics. Our observations suggest a role for Brachyspira in the pathogenesis of IBS, particularly IBS-D.
Infectious disease surveillance of apparently healthy horses at a multi-day show using a novel nanoscale real-time PCR panel

In the United States, horses are used for a variety of purposes including recreation, exhibition, and racing. As farm, performance, and companion animals, horses are a unique species from a zoonotic disease risk perspective, and the risks of subclinical infections spreading among horses can pose challenges. Using a nanoscale real-time PCR platform, we investigated the prevalence of 14 enteric pathogens, 11 Escherichia coli genes, and 9 respiratory pathogens in fecal samples from 97 apparently healthy horses at a multi-day horse event. In addition, sugar flotation test was performed for fecal parasites. E. coli f17 was commonly detected, prevalent in 59% of horses, followed closely by Streptococcus equi subsp. zooepidemicus (55%). Additional pathogens recognized included betacoronavirus, Campylobacter jejuni, Cryptosporidium sp. , E. coli O157, equine adenovirus 1, equine rhinitis B virus, and others. The use of PCR data may overestimate the true prevalence of these pathogens but provides a sensitive overview of common pathogens present in healthy horses. Our results prompt the continued need for practical biosecurity measures at horse shows, both to protect individuals interacting with these horses and to minimize transmission among horses.
Mitochondria and nucleus cross‐talk: Signaling in metabolism, apoptosis, and differentiation, and function in cancer

The cross‐talk between the mitochondrion and the nucleus regulates cellular functions, including differentiation and adaptation to stress. Mitochondria supply metabolites for epigenetic modifications and other nuclear‐associated activities and certain mitochondrial proteins were found in the nucleus. The voltage‐dependent anion channel 1 (VDAC1), localized at the outer mitochondrial membrane (OMM) is a central protein in controlling energy production, cell growth, Ca2+ homeostasis, and apoptosis. To alter the cross‐talk between the mitochondria and the nucleus, we used specific siRNA to silence the expression of VDAC1 in glioblastoma (GBM) U87‐MG and U118‐MG cell‐derived tumors, and then monitored the nuclear localization of mitochondrial proteins and the methylation and acetylation of histones. Depletion of VDAC1 from tumor cells reduced metabolism, leading to inhibition of tumor growth, and several tumor‐associated processes and signaling pathways linked to cancer development. In addition, we demonstrate that certain mitochondrial pro‐apoptotic proteins such as caspases 3, 8, and 9, and p53 were unexpectedly overexpressed in tumors, suggesting that they possess additional non‐apoptotic functions. VDAC1 depletion and metabolic reprograming altered their expression levels and subcellular localization, specifically their translocation to the nucleus. In addition, VDAC1 depletion also leads to epigenetic modifications of histone acetylation and methylation, suggesting that the interchange between metabolism and cancer signaling pathways involves mitochondria‐nucleus cross‐talk. The mechanisms regulating mitochondrial protein trafficking into and out of the nucleus and the role these proteins play in the nucleus remain to be elucidated.
Spontaneous homeotic mutants and genetic control of floral organ identity in a ranunculid

The regulation of floral organ identity was investigated using a forward genetic approach in five floral homeotic mutants of Thalictrum, a noncore eudicot. We hypothesized that these mutants carry defects in the floral patterning genes. Mutant characterization comprised comparative floral morphology and organ identity gene expression at early and late developmental stages, followed by sequence analysis of coding and intronic regions to identify transcription factor binding sites and protein–protein interaction (PPI) motifs. Mutants exhibited altered expression of floral MADS‐box genes, which further informed the function of paralogs arising from gene duplications not found in reference model systems. The ensuing modified BCE models for the mutants supported instances of neofunctionalization (e.g., B‐class genes expressed ectopically in sepals), partial redundancy (E‐class), or subfunctionalization (C‐class) of paralogs. A lack of deleterious mutations in the coding regions of candidate floral MADS‐box genes suggested that cis‐regulatory or trans‐acting mutations are at play. Consistent with this hypothesis, double‐flower mutants had transposon insertions or showed signs of transposon activity in the regulatory intron of AGAMOUS (AG) orthologs. Single amino acid substitutions were also found, yet they did not fall on any of the identified DNA binding or PPI motifs. In conclusion, we present evidence suggesting that transposon activity and regulatory mutations in floral homeotic genes likely underlie the striking phenotypes of these Thalictrum floral homeotic mutants.
Interrupted versus continuous magnesium sulfate and blood loss at cesarean delivery

Abstract Objective Magnesium sulfate is standard of care for prevention of eclampsia in women with preeclampsia with severe features. The American College of Obstetrics and Gynecology endorses its use throughout labor, delivery and the immediate postpartum period. Some providers pause magnesium sulfate infusion preoperatively due to concern for increased risk of uterine atony and postpartum hemorrhage. Using a non-inferiority analysis, we investigated the effect of interrupted versus continuous infusion of magnesium sulfate on postpartum hemorrhage in women with preeclampsia with severe features undergoing cesarean delivery. Study design Retrospective non-inferiority cohort study of women with preeclampsia with severe features treated with magnesium sulfate undergoing cesarean delivery with singleton pregnancies at tertiary care hospital from 2013 to 2018. The primary outcome was postpartum hemorrhage. Secondary outcomes included estimated blood loss, change in hematocrit and a composite of postpartum hemorrhage severity, including transfusion of blood products, use of more than one uterotonic and additional surgical interventions. Results Of 249 women, magnesium sulfate infusion was interrupted in 171 (69%) and continued in 78 (31%). Women with interrupted magnesium sulfate infusion were more likely to be Caucasian (73% vs 67%, p = .024), have chronic hypertension (23% vs 1%, p < .001), labor prior to cesarean delivery (84% vs 55%, p < .001), undergo primary cesarean delivery (86% vs 67%, p = .005), and experience shorter surgical time (50 vs 55 min, p = .026). The rate of postpartum hemorrhage for those receiving interrupted magnesium sulfate infusion (9.9%) and continuous magnesium sulfate infusion (10.2%) was similar, falling within the non-inferiority margin (absolute difference 0.3%, 95% CI -7.8 to 8.4%, p = .88). There were no significant differences in the secondary outcomes. Conclusion Interrupted magnesium sulfate infusion is non-inferior to continued magnesium sulfate infusion for rates of postpartum hemorrhage in women with preeclampsia with severe features undergoing cesarean delivery.
Fate and propagation of endogenously formed Tau aggregates in neuronal cells

Tau accumulation in the form of neurofibrillary tangles in the brain is a hallmark of tauopathies such as Alzheimer's disease (AD). Tau aggregates accumulate in brain regions in a defined spatiotemporal pattern and may induce the aggregation of native Tau in a prion‐like manner. However, the underlying mechanisms of cell‐to‐cell spreading of Tau pathology are unknown and could involve encapsulation within exosomes, trans‐synaptic passage, and tunneling nanotubes (TNTs). We have established a neuronal cell model to monitor both internalization of externally added fibrils, synthetic (K18) or Tau from AD brain extracts, and real‐time conversion of microtubule‐binding domain of Tau fused to a fluorescent marker into aggregates. We found that these endogenously formed deposits colabel with ubiquitin and p62 but are not recruited to macroautophagosomes, eventually escaping clearance. Furthermore, endogenous K18‐seeded Tau aggregates spread to neighboring cells where they seed new deposits. Transfer of Tau aggregates depends on direct cell contact, and they are found inside TNTs connecting neuronal cells. We further demonstrate that contact‐dependent transfer occurs in primary neurons and between neurons and astrocytes in organotypic cultures.
Optimized Doxorubicin Chemotherapy for Diffuse Large B-cell Lymphoma Exploits Nanocarrier Delivery to Transferrin Receptors

Targeted nanoparticle delivery of doxorubicin chemotherapy via the TRF1 receptor presents a new opportunity against high-risk DLBCL tumors using potency and precision. New treatments are needed to address persistent unmet clinical needs for diffuse large B-cell lymphoma (DLBCL). Overexpression of transferrin receptor 1 (TFR1) is common across cancer and permits cell-surface targeting of specific therapies in preclinical and clinical studies of various solid tumors. Here, we developed novel nanocarrier delivery of chemotherapy via TFR1-mediated endocytosis, assessing this target for the first time in DLBCL. Analysis of published datasets showed novel association of increased TFR1 expression with high-risk DLBCL cases. Carbon–nitride dots (CND) are emerging nanoparticles with excellent in vivo stability and distribution and are adaptable to covalent conjugation with multiple substrates. In vitro, linking doxorubicin (Dox) and transferrin (TF) to CND (CND–Dox–TF, CDT) was 10–100 times more potent than Dox against DLBCL cell lines. Gain- and loss-of-function studies and fluorescent confocal microscopy confirmed dependence of these effects on TFR1-mediated endocytosis. In contrast with previous therapeutics directly linking Dox and TF, cytotoxicity of CDT resulted from nuclear entry by Dox, promoting double-stranded DNA breaks and apoptosis. CDT proved safe to administer in vivo, and when incorporated into standard frontline chemoimmunotherapy in place of Dox, it improved overall survival by controlling patient-derived xenograft tumors with greatly reduced host toxicities. Nanocarrier-mediated Dox delivery to cell-surface TFR1, therefore, warrants optimization as a potential new therapeutic option in DLBCL. Significance: Targeted nanoparticle delivery of doxorubicin chemotherapy via the TRF1 receptor presents a new opportunity against high-risk DLBCL tumors using potency and precision.
What Strategies Are Hospitals Adopting to Address the Opioid Epidemic? Evidence From a National Sample of Nonprofit Hospitals

Objectives Hospitals are on the front lines of the opioid epidemic, seeing patients who overdose or have complicated infections, but the extent of services offered or whether services are evidence-based is not known. The objective of our study was to assess the extent to which nonprofit hospitals are addressing opioid abuse, a critical public health issue, through their community benefit work and to identify which evidence-based strategies they adopt. Methods We reviewed community benefit documents from January 1, 2015, through December 31, 2018, for a sample (N = 446) of all nonprofit hospitals in the United States. We classified hospital opioid-related strategies into 9 categories. Using logistic regression, we predicted the likelihood of hospitals adopting various strategies to address opioid abuse. Results Of the 446 nonprofit hospitals in our sample, 49.1% (n = 219) adopted ≥1 clinical strategy to address opioid use disorder in their community. Approximately one-quarter (26.5%; n = 118) of hospitals adopted a strategy related to treatment services for substance use disorder; 28.2% (n = 126) had ≥1 program focused on connecting patients to a primary care medical home, and 14.6% (n = 65) focused on caring for patients with opioid-related overdoses in the emergency department. We also identified factors that predicted involvement in programs that were less common than clinical strategies, but potentially effective, such as harm reduction and prescriber initiatives (both 6.3% of hospitals). Conclusions Evidence-based prevention and treatment require strong collaboration between health care and community institutions at all levels. Effective policy interventions may exist to encourage various types and sizes of nonprofit hospitals to adopt evidence-based interventions to address opioid abuse in their communities.
Partial and complete dependency among data sets has minimal consequence on estimates from integrated population models.

Integrated population models (IPMs) are widely used to combine disparate data sets in joint analysis to better understand population dynamics and provide guidance for conservation activities. An often-cited assumption of IPMs is independence among component data sets within the combined likelihood. Dependency among data sets should lead to underestimation of variance and bias because individuals contribute data to> 1 data set. In practice, studied individuals often occur in multiple data sets in IPMs (i.e., overlap), which is one way for the independence assumption to be violated. Such cases have the potential to dissuade practitioners and limit application of IPMs to solve emerging ecological problems. We assessed precision and bias of demographic rates estimated from IPMs using a complete gradient (0-100%) of overlap among data sets, wide ranges in demographic rates (e.g., survival 0.1-0.8) and sample sizes (100-1200 individuals) and variable data sources. We compared results from our simulations with those from IPMs constructed using empirical data on tree swallows (Tachycineta bicolor) where data sets either had complete overlap or included different individuals. Contrary to previous investigators, we found no substantive bias or uncertainty in any demographic rate from IPMs derived from data sets with complete overlap. While variability in demographic rates was greater at low sample sizes (i.e., low capture, recapture and survey probabilities), there were negligible differences in the posterior mean or root mean square error of demographic rates among IPMs with strong dependence versus complete independence among data sets. Our simulations suggest IPMs can be designed using only capture-recapture data or harvest and capture-recovery data where population estimates are obtained from the same data as survival and productivity data. While we encourage researchers to carefully consider the modeling approach best-suited for their data sets, our results suggest that dependence among data sets does not generally compromise IPM estimates. Thus, violation of the independence assumption should not dissuade researchers from the application of IPMs in ecological research.
Preliminary evaluation of an inter-professional e-consultation on vaccines

The aim of this study was to assess the preliminary effectiveness and acceptability of an inter-professional e-consultation on vaccines. We used a quasi-experimental design to introduce an application in electronic health records that allowed primary health providers to launch e-consults to the hospital vaccines unit. A total of 135 e-consults were received during 10 months. E-consults were more frequently about subjects with chronic diseases (82.2%). Most of the e-consults were global (60.7%), that is, to revise a patient’s complete vaccination schedule, whereas 39.3% were specific, that is, to request information regarding a concrete vaccine or serology, with hepatitis vaccines leading the ranking (42.9%). The e-consultation avoided hospital referral in 85.4% of the global e-consults and in 100% of the specific e-consults. Indicators of acceptability were all above nine points (10 points indicated the maximum). The best-rated aspect was the level of recommendation (9.7 ± 0.68 points). In summary, linking primary health-care providers with specialists in vaccines through an e-consultation tool is effective and well-accepted by users.
