Antipsychotic prescribing patterns on admission to and discharge from a tertiary care program for treatment-resistant psychosis at Riverview Hospital
Creators: name: Lee, Lik Hang
Publisher: name: University of British Columbia
Year: 2019

description: The treatment of psychosis typically requires the use of only one antipsychotic. Even in instances of treatment-resistant psychosis, the atypical antipsychotic clozapine has proven to be effective when used on its own. However, antipsychotic polypharmacy is commonly prescribed despite a lack of evidence for this practice. This concurrent use of two or more antipsychotics can also prolong the time before clozapine is tried. Antipsychotic polypharmacy should be reserved for instances of clozapine-resistant psychosis if it is to be used at all. In this retrospective study, data were collected from individuals who were referred to a tertiary care program for treatment-resistant psychosis. The main objectives were to compare the use of antipsychotic monotherapy to polypharmacy in treatment-resistant psychosis and to characterize within-individual changes in treatment and symptomatology secondary to hospitalization. At admission, individuals who were prescribed only one antipsychotic were comparable to those who were prescribed at least two antipsychotics with regard to demographics and symptom severity. The use of drugs other than antipsychotics was also similar between groups. However, the magnitude of antipsychotic utilization was greater in individuals who were receiving antipsychotic polypharmacy. In addition, a greater proportion of these individuals received excessive doses at admission. Similar findings were observed when monotherapy and polypharmacy were compared at discharge. Three important patterns were identified when investigating within-individual changes. First, fewer individuals were on polypharmacy at discharge. This was accompanied by a general decrease in both the number of antipsychotics prescribed and the magnitude of antipsychotic utilization. Second, the number of individuals who were prescribed clozapine had increased by discharge. Those who were already prescribed clozapine at admission typically had their doses increased. Third, improvements in symptomatology were observed across all of the subscales included in the Positive and Negative Syndrome Scale (PANSS). However, only 57.9% of individuals experienced a relative reduction in PANSS scores greater than 20%. Based on these findings, it is possible to alleviate the symptoms of psychosis in treatment-resistant psychosis while reducing antipsychotic utilization. Although this may seem counterintuitive, an increase in the use of clozapine and a decrease in antipsychotic polypharmacy may have contributed to clinical improvement.

description: Cellular nucleic acid levels are specifically regulated by Argonaute (Ago) proteins. Eukaryotic (e)Ago participates mainly in posttranscriptional regulation of gene expression. In contrast, prokaryotic (p)Ago proteins are involved in defense processes. Our work adds to the understanding of pAgo function and elucidates dynamic aspects of Ago-mediated substrate binding thereby highlighting mechanistic differences between eAgo and pAgo proteins.

description: Emotional states have been indicated to affect intentional binding, resulting in an increase or decrease as a function of valence and arousal. Sexual arousal is a complex emotional state proven to impair attentional and perceptual processes, and is therefore highly relevant to feeling in control over one’s actions. We suggest that sexual arousal affects intentional binding in the same way as highly negative arousing states such as fear and anger. Ninety participants performed the intentional binding task before and after watching an either sexually arousing or emotionally neutral film clip. Analyses were conducted for the subcomponents action and outcome binding separately including the change in arousal before and after the emotion induction as a continuous measure. Results showed an interactive effect for time of measurement (before and after emotion induction) and arousal change on action binding: a decrease in action binding was noted in participants who reported to be more aroused and an increase in action binding was observed for participants who reported to be less aroused. Results emphasize that alterations in action binding are likely to reflect the deficits in the dopaminergic system involved in action execution. An impaired feeling of control in aroused states may play a crucial role for the underlying psychological mechanisms of impulsive violent behavior.

description: Using the formalism of constrained superfields, we derive the most general effective action of a light goldstino coupled to the minimal supersymmetric standard model (MSSM) and study its phenomenological consequences. The goldstino-induced couplings become important when the (hidden sector) scale of spontaneous supersymmetry breaking, $\sqrt f$, is relatively low, of the order of few TeV. In particular, we compute the Higgs potential and show that the (tree level) mass of the lightest Higgs scalar can be increased to the LEP bound for $\sqrt f\sim 2$ TeV to 7 TeV. Moreover, the effective quartic Higgs coupling is increased due to additional tree-level contributions proportional to the ratio of visible to hidden sector supersymmetry breaking scales. This increase can alleviate the amount of fine tuning of the electroweak scale that exists in the MSSM. Among the new goldstino couplings, beyond those in MSSM, the most important ones generate an invisible decay of the Higgs boson into a goldstino and neutralino (if m_h>m_{χ_1^0}), with a partial decay rate that can be comparable to the SM channel h^0-> γγ. A similar decay of Z boson is possible if m_Z>m_{χ_1^0} and brings a lower bound on $\sqrt f$ that must be of about 700 GeV. Additional decay modes of the Higgs or Z bosons into a pair of light goldstinos, while possible, are suppressed by an extra 1/f factor and have no significant impact on the model.

description: ATP-dependent DEAD-box helicases constitute one of the largest families of RNA helicases and are important regulators of most RNA-dependent cellular processes. The functional core of these enzymes consists of two RecA-like domains. Changes in the interdomain orientation of these domains upon ATP and RNA binding result in the unwinding of double-stranded RNA. The DEAD-box helicase DbpA from E. coli is involved in ribosome maturation. It possesses a C-terminal RNA recognition motif (RRM) in addition to the canonical RecA-like domains. The RRM recruits DbpA to nascent ribosomes by binding to hairpin 92 of the 23S rRNA. To follow the conformational changes of Dbpa during the catalytic cycle we initiated solution state NMR studies. We use a divide and conquer approach to obtain an almost complete resonance assignment of the isoleucine, leucine, valine, methionine and alanine methyl group signals of full length DbpA (49 kDa). In addition, we also report the backbone resonance assignments of two fragments of DbpA that were used in the course of the methyl group assignment. These assignments are the first step towards a better understanding of the molecular mechanism behind the ATP-dependent RNA unwinding process catalyzed by DEAD-box helicases.

Hilbert schemes of points on a locally planar curve and the Severi strata of its versal deformation
Creators: name: Shende, Vivek

Subjects: subject: Algebraic Geometry (math.AG)
subject: FOS: Mathematics

description: Let C be a locally planar curve. Its versal deformation admits a stratification by the genera of the fibres. The strata are singular; we show that their multiplicities at the central point are determined by the Euler numbers of the Hilbert schemes of points on C. These Euler numbers have made two prior appearances. First, in certain simple cases, they control the contribution of C to the Pandharipande-Thomas curve counting invariants of three-folds. In this context, our result identifies the strata multiplicities as the local contributions to the Gopakumar-Vafa BPS invariants. Second, when C is smooth away from a unique singular point, a special case of a conjecture of Oblomkov and Shende identifies the Euler numbers of the Hilbert schemes with the "U(infinity)" invariant of the link of the singularity. We make contact with combinatorial ideas of Jaeger, and suggest an approach to the conjecture.

description: Developing students' global awareness and competencies is crucial in our increasingly interconnected world. This qualitative case study explored what influences social studies teachers' curricular decisions regarding incorporating global topics into their classrooms. The study focused specifically on five high school teachers in Indiana, USA who identified as interested in global education. Data collection involved individual semi-structured interviews, classroom observations, and document analysis. Interviews provided insights into teachers' purposes, goals, barriers, and decision-making regarding global curriculum integration. Observations and teaching artifacts offered direct evidence of classroom practices. Data was coded using a flexible inductive-deductive approach incorporating both data-driven and theory-driven codes.Key findings were that teachers' own global experiences and mindsets strongly shaped their desire to develop students' global perspectives, despite facing external constraints like standardized curriculum and testing requirements. Teachers were driven by aims to expand students' worldviews, foster cultural appreciation, build skills for an interdependent world, and ignite passion for lifelong global learning. However, restrictive standards, content sequencing, and time limitations posed challenges. Still, internally driven teachers leveraged their agency as curricular gatekeepers to creatively infuse global topics through discussions, activities, and resources aligned with mandated outcomes. The study highlights the importance of developing internal global orientations in teachers while allowing curricular flexibility for meaningful global education. Findings inform efforts in teacher training, hiring, and professional development to support global citizenship teaching within systemic bounds.

Single-crystal X-ray diffraction measurements show the compound to be a coordination polymer with the Cu(II) ions alternately bridged in μ1,1- and μ1,3-fashion by the formate ions. The sodium ions are coordinated to both formate ions and perchlorate ions in the lattice. Magnetic measurements were made over the range 1.8-310 K and show the presence of a singlet ground state at low temperature, the µ1,1-bridged copper ions being strongly antiferromagnetically coupled. The data were modeled equally well, within experimental error, by the alternating chain model and the dimer model with a Curie-Weiss correction for weak inter-dimer interactions, yielding C = 0.432(2) emu-K/mol-Oe, J/kB = −94.3(9) K and J’ = −2.4(1.5) K (H= −J∑S1·S2).

description: Previous analysis of CFTR-knockout (CFTR−/−) in piglets has provided important insights into the pathology of cystic fibrosis. However, controversies exist as to the true contribution of CFTR to the pH balance in airways and intestine. We therefore compared ion transport properties in newborn wild-type (CFTR+/+) and CFTR-knockout (CFTR−/− piglets). Tracheas of CFTR−/− piglets demonstrated typical cartilage malformations and muscle cell bundles. CFTR−/− airway epithelial cells showed enhanced lipid peroxidation, suggesting inflammation early in life. CFTR was mainly expressed in airway submucosal glands and was absent in lungs of CFTR−/− piglets, while expression of TMEM16A was uncompromised. mRNA levels for TMEM16A, TMEM16F, and αβγENaC were unchanged in CFTR−/− airways, while mRNA for SLC26A9 appeared reduced. CFTR was undetectable in epithelial cells of CFTR−/− airways and intestine. Small intestinal epithelium of CFTR−/− piglets showed mucus accumulation. Secretion of both electrolytes and mucus was activated by stimulation with prostaglandin E2 and ATP in the intestine of CFTR+/+, but not of CFTR−/− animals. pH was measured inside small bronchi using a pH microelectrode and revealed no difference between CFTR+/+ and CFTR−/− piglets. Intracellular pH in porcine airway epithelial cells revealed only a small contribution of CFTR to bicarbonate secretion, which was absent in cells from CFTR−/− piglets. In contrast to earlier reports, our data suggest a minor impact of CFTR on ASL pH. In contrast, enhanced amiloride-sensitive Na+ absorption may contribute to lung pathology in CFTR−/− piglets, along with a compromised CFTR- and TMEM16A-dependent Cl− transport.

description: Proteins and nucleic acids are highly dynamic bio-molecules that can populate a variety of conformational states. NMR relaxation dispersion (RD) methods are uniquely suited to quantify the associated kinetic and thermodynamic parameters. Here, we present a consistent suite of ¹⁹F-based CPMG, on resonance R₁ρ and off-resonance R₁ρ RD experiments. We validate these experiments by studying the unfolding transition of a 7.5 kDa cold shock protein. Furthermore we show that the ¹⁹F RD experiments are applicable to very large molecular machines by quantifying dynamics in the 360 kDa half proteasome. Our approach significantly extends the timescale of chemical exchange that can be studied with ¹⁹F RD, adds robustness to the extraction of exchange parameters and can determine the absolute chemical shifts of excited states. Importantly, due to the simplicity of ¹⁹F NMR spectra, it is possible to record complete datasets within hours on samples that are of very low costs. This makes the presented experiments ideally suited to complement static structural information from cryo-EM and X-ray crystallography with insights into functionally relevant motions.

description: The complexes trans/cis-[RuCl2(DPEphos)(ampy)] (trans – 1a; cis – 1b) and trans/cis-[RuCl2(DPEphos)(en)] (trans – 2a; cis – 2b) were obtained from the reactions of mer-[RuCl2(DPEphos)(PPh3)] (PPh3 = triphenylphosphine) with the corresponding amine in CH2Cl2. The isomer 1a was observed in situ when the reaction was carried out at r.t.; isolation leads to mixtures with 1b, while the latter was isolated when the reaction was performed under reflux. On the other hand, trans-[RuCl2(DPEphos)(en)] (2a) was obtained at r.t., in good yield and the cis-isomer 2b was observed when the reaction was carried out under reflux or when a CH2Cl2 solution of 2a is exposed to ambient light, but 2b was not isolated in pure form even under reflux for one week. Cyclic voltammetry studies revealed the presence of one reversible process with E1/2 0.57 and 0.40 V for 1b and 2a, respectively. Both 1b and 2a were used as pre-catalysts for reduction of acetophenone and p-substituted acetophenones (F–, Me– and MeO–) in transfer-hydrogenation conditions (isopropanol, 82 °C, and pre-catalyst:KOH:acetophenones in molar ratio 1:20:500 and/or 1:20:1000) showing conversions of 93–99% and TOF values up to 4.2 104 h−1.

description: Let S be a minimal complex surface of general type with irregularity q>=2 and let C be an irreducible curve of geometric genus g contained in S. Assume that C is "Albanese defective", i.e., that the image of C via the Albanese map does not generate the Albanese variety Alb(S); we obtain a linear upper bound in terms of K^2_S and g for the canonical degree K_SC of C. As a corollary, we obtain a bound for the canonical degree of curves with g<= q-1, thereby generalizing and sharpening the main result of [S.Y. Lu, On surfaces of general type with maximal Albanese dimension, J. Reine Angew. Math. 641 (2010), 163-175].

description: We perform an su(2) Hamiltonian reduction in the bosonic sector of the su(2)-invariant action for two free (4, 4, 0) supermultiplets. As a result, we get the five dimensional N=4 supersymmetric mechanics describing the motion of an isospin carrying particle interacting with a Yang monopole. We provide the Lagrangian and Hamiltonian descriptions of this system. Some possible generalizations of the action to the cases of systems with a more general bosonic action, a four-dimensional system which still includes eight fermionic components, and a variant of five-dimensional N=4 mechanics constructed with the help of the ordinary and twisted N=4 hypermultiplets were also considered.

description: Die vorliegende Studie stellt eine Replikation des quantitativen Teils der Studie von Rank (2008, 2009) dar, in der die bei Fachkräften vorhandenen pädagogischen Orientierungen zum vorschulischen Lernen und Schriftspracherwerb untersucht wurden. An der erneuten Erhebung im Jahr 2016 mit demselben Fragebogen nahmen 147 Fachkräfte teil. Die Ergebnisse belegen eine nach wie vor hohe Zustimmung zum Kindergarten als Lernort. Selbstgesteuerter Schriftspracherwerb wird allerdings signifikant häufiger abgelehnt als noch vor zehn Jahren. Als signifikante Prädiktoren hierbei zeigen sich in der Regressionsanalyse ein instruierendes Lernkonzept und Unsicherheit gegenüber der Schule. Abstract The present study is a replication of the quantitative part of Rank’s study (2008, 2009), in which data about the pedagogical orientation of preschool teachers were collected. The replication reached 147 preschool teachers. The same questionnaire was used as in Rank 2008, 2009. There is still a high level of agreement with the kindergarten as a place of learning. The rejection of self-directed writing is significantly higher than ten years ago. The regression analysis shows an instructive learning concept and uncertainty towards school as significant predictors.

description: Motivated by complex multi-fluid geometries currently being explored in fibre-device manufacturing, we study capillary instabilities in concentric cylindrical flows of $N$ fluids with arbitrary viscosities, thicknesses, densities, and surface tensions in both the Stokes regime and for the full Navier--Stokes problem. Generalizing previous work by Tomotika (N=2), Stone & Brenner (N=3, equal viscosities) and others, we present a full linear stability analysis of the growth modes and rates, reducing the system to a linear generalized eigenproblem in the Stokes case. Furthermore, we demonstrate by Plateau-style geometrical arguments that only axisymmetric instabilities need be considered. We show that the N=3 case is already sufficient to obtain several interesting phenomena: limiting cases of thin shells or low shell viscosity that reduce to N=2 problems, and a system with competing breakup processes at very different length scales. The latter is demonstrated with full 3-dimensional Stokes-flow simulations. Many $N > 3$ cases remain to be explored, and as a first step we discuss two illustrative $N \to \infty$ cases, an alternating-layer structure and a geometry with a continuously varying viscosity.
Critical thinking in the content and language integrated classroom : perceptions of secondary mathematics teachers in overseas Canadian curriculum contexts
Creators: name: Li, Tian
Publisher: name: University of British Columbia
Year: 2017

description: This qualitative study explores the impacts of Content and Language Integrated Learning (CLIL) on students’ mathematical critical thinking development in Canadian offshore secondary schools. Critical thinking is a necessary ability in modern society. Until now, the relationship between CLIL and mathematical critical thinking has not been fully examined, particularly in Canadian offshore schools. The objective of this study was to examine the impacts of CLIL in secondary mathematics in Canadian offshore schools for students from non-native English speaking backgrounds. The overarching research question for this study was: How do mathematics teachers working in schools using a hybrid Canadian and Chinese curriculum in China perceive the impacts of CLIL on the development of mathematical critical thinking in secondary students? Qualitative methods contributed to a study design that combined an email questionnaire and follow-up interviews to triangulate data for analysis. A constructivist theoretical framework supported the analysis of the data. Data indicated that CLIL could affect students’ mathematical critical thinking development positively and negatively, as well as directly and indirectly. Three prominent themes, with a number of subthemes, were found throughout the data, including critical thinking, CLIL in mathematics classrooms, and critical thinking and CLIL. Participants referred to external and internal factors that could influence critical thinking development in CLIL and their beliefs related to CLIL. Those beliefs had major effects on pedagogical choices and, as a result, could influence the development of critical thinking skills. The results of this study can assist CLIL instructors in seeing what and how various factors affect students’ critical thinking, thus creating better conditions for students to develop mathematical critical thinking. The findings point to future research related to gathering more perspectives and experiences of secondary mathematics teachers at other Canadian offshore schools.

description: In the domain of visual arts, professional artists usually graduate from academies and universities. For professional development, art students must practise domain-specific activities. Support from lecturers and exchanges with fellow students also help advance accomplishments. Amateurs without academic or vocational artistic education can acquire their skills autodidactically or attend courses such as those at an adult-education centre. Empirical research in the domain of visual arts remains scarce; therefore, the present study’s objective was to analyse which kinds of domain-specific practice activities and social interactions artists, intermediates and amateurs rate as relevant to their artistic development in visual arts. The Professional Development in Arts Questionnaire (PDA-Q), including closed and open questions, was developed to examine artists’ activities and interactions. In this study, 81 experts, 58 intermediates and 31 amateurs participated. Experts and intermediates perceived domain-specific practice activities working on artworks and reflecting as the most important in their professional development. Experts and intermediates also rated these two activities as the most demanding. Amateurs rated these activities as less relevant and demanding. Experts and intermediates most often received feedback from lecturers and fellow students, while amateurs most often received feedback from friends and family. Experts and intermediates cited lecturers as being the most helpful sources of feedback, while amateurs cited family.

description: In this paper, the production rates of quarkonia eta_c, J/psi, eta_b, Upsilon, B_c and B_c^* through W boson decay at the LHC are calculated, at the leading order in both the QCD coupling constant and in v, the typical velocity of the heavy quark inside of mesons. It shows that a sizable number of quarkonia from W boson decay will be produced at the LHC. Comparison with the predictions by using quark fragmentation mechanism is also discussed. Results show that, for the charmonium production through W decay, the difference between predictions by the fragmentation mechanism and complete leading order calculation is around 3%, and it is insensitive to the uncertainties of theoretical parameters; however, for the bottomonium and B_c^(*) productions, the difference cannot be ignored as the fragmentation mechanism is less applicable here due to the relatively large ratio mb/mw.

description: Catalytic hydrogenation of β-himachalene, the main constituent of Atlas cedar’s essential oil, led to the formation of β-8,9-dihydrohimachalene (2,6,6,9-tetramethylbicyclo[5.4.0]undeca-1-ene). This latter when treated with palladium(II) chloride gives neutral bis(chloro)-bridged cyclopalladated dimers, [Pd2C12(C15H25)2] (di-μ-chloro-bis{[(1,2,15-η)-2,6,6,9-tetramethylbicyclo[5.4.0]undeca-1-ene]palladium), with a high regio- and stereoselectivity, which is stable under air and moisture. Its reaction with triphenylphosphine provided a monomer (π-allyl-β-8,9-dihydrohimachalene) palladium(triphenylphosphine) complex. Both complexes were characterized by 1H and 13C NMR spectroscopy and single crystal X-ray diffraction. DFT calculations were conducted on both compounds in order to predict their optimized structures, the frontier molecular orbitals and the global reactivity descriptors. A good correlation of bond lengths and angles with the experimental data was found at the B3LYP/6-31 +G(d,p) basis set. Moreover, Hirshfeld surface (HS) and 2D fingerprint analyses revealed an intermolecular hydrogen bond of 2.56 Å for the monomer palladium complex, which is close to the experimental value, along with an intramolecular close contact dominated by H-H interactions in both compounds.

description: Many fixed-parameter tractable algorithms using a bounded search tree have been repeatedly improved, often by describing a larger number of branching rules involving an increasingly complex case analysis. We introduce a novel and general search strategy that branches on the forbidden subgraphs of a graph class relaxation. By using the class of $P_4$-sparse graphs as the relaxed graph class, we obtain efficient bounded search tree algorithms for several parameterized deletion problems. We give the first non-trivial bounded search tree algorithms for the cograph edge-deletion problem and the trivially perfect edge-deletion problems. For the cograph vertex deletion problem, a refined analysis of the runtime of our simple bounded search algorithm gives a faster exponential factor than those algorithms designed with the help of complicated case distinctions and non-trivial running time analysis [21] and computer-aided branching rules [11].

description: Following the recent successful synthesis and characterization of bulk SnTiO3, its energy landscape was studied by means of density functional theory, applying different exchange–correlation and hybrid functionals. Experimentally accessible structure candidates with composition ABX3 were identified by a database search and global exploration approach. Besides the common octahedral coordination of Ti, also fourfold and fivefold coordination spheres emerged to be reasonable structural motifs. Among the predicted high-pressure modifications, the tetragonal perovskite structure turned out to be stable at pressures between 11 GPa and 15 GPa. The possibility of a paraelectric-to-ferroelectric phase transition of the tetragonal perovskite structure was investigated by modeling the phonon spectra and soft mode behavior. Despite substantial long wavelength transverse optical mode softening, the predicted high c/a-ratio in tetragonal perovskite SnTiO3 inhibits the formation of a spontaneous reversible polarization.

description: Borrowing from concepts in expander graphs, we study the expansion properties of real-world, complex networks (e.g. social networks, unstructured peer-to-peer or P2P networks) and the extent to which these properties can be exploited to understand and address the problem of decentralized search. We first produce samples that concisely capture the overall expansion properties of an entire network, which we collectively refer to as the expansion signature. Using these signatures, we find a correspondence between the magnitude of maximum expansion and the extent to which a network can be efficiently searched. We further find evidence that standard graph-theoretic measures, such as average path length, fail to fully explain the level of "searchability" or ease of information diffusion and dissemination in a network. Finally, we demonstrate that this high expansion can be leveraged to facilitate decentralized search in networks and show that an expansion-based search strategy outperforms typical search methods.

description: Background Ultrasound diagnostics are widely used and are standard for radiologists, otolaryngologists, and oral and maxillofacial surgeons in the diagnostic work-up of various pathologies. There is agreement that digital documentation is urgently needed at present to improve and standardize the quality of sonographic documentation. There are more and more publications on the implementation of standardized documentation of findings in imaging diagnostics, including head and neck sonography. Objective The present work aims to determine the quality of routine head and neck sonography findings on a random basis, according to the criteria of the Bavarian Association of Statutory Health Insurance Physicians (KVB) at a selection of German university otolaryngology departments (ENT). Materials and methods A total of 70 randomly selected anonymized written findings including image documentation from seven ENT departments were retrospectively analyzed by an experienced KVB examiner concerning fulfilment of KVB criteria. The data were evaluated descriptively. Results Of the 70 reports, 69 were eligible for evaluation. The average documentation completeness was 80.6%. A total of 9 findings were correctly documented in full (13%). The documentation completeness of the individual departments was sorted in ascending order from 68.1% to 93%. With 88.5% vs. 75%, the hospitals with a structured report showed a higher level of completeness. In 75% of the cases the hospitals with structured reports also had digital solutions for reporting and image archiving. Conclusion In general, there is potential for optimization regarding the completeness and quality of routinely prepared head and neck sonography findings at the selected university ENT departments. The implementation of structured reporting masks and the conversion of analogue documentation into digital solutions as well as digital networking with the hospital information systems, picture archiving and communication systems should be promoted. Supervision by senior doctors is required to ensure the quality of findings of inexperienced colleagues and to help to achieve standards in reporting.

description: This review presents the state-of-the-art of optical sensors for determination of biogenic amines (BAs) in food by publications covering about the last 10 years. Interest in the development of rapid and preferably on-site methods for quantification of BAs is based on their important role in implementation and regulation of various physiological processes. At the same time, BAs can develop in different kinds of food by fermentation processes or microbial activity or arise due to contamination, which induces toxicological risks and food poisoning and causes serious health issues. Therefore, various optical chemosensor systems have been devised that are easy to assemble and fast responding and low-cost analytical tools. If amenable to on-site analysis, they are an attractive alternative to existing instrumental analytical methods used for BA determination in food. Hence, also portable sensor systems or dipstick sensors are described based on various probes that typically enable signal readouts such as photometry, reflectometry, luminescence, surface-enhanced Raman spectroscopy, or ellipsometry. The quantification of BAs in real food samples and the design of the sensors are highlighted and the analytical figures of merit are compared. Future instrumental trends for BA sensing point to the use of cell phone–based fully automated optical evaluation and devices that could even comprise microfluidic micro total analysis systems.

description: Multi-analyte sensing using exclusively laser-induced graphene (LIG)-based planar electrode systems was developed for sweat analysis. LIG provides 3D structures of graphene, can be manufactured easier than any other carbon electrode also on large scale, and in form of electrodes: hence, it is predestinated for affordable, wearable point-of-care sensors. Here, it is demonstrated that LIG facilitates all three electrochemical sensing strategies (voltammetry, potentiometry, impedance) in a multi-analyte system for sweat analysis. A potentiometric potassium-ion-selective electrode in combination with an electrodeposited Ag/AgCl reference electrode (RE) enabled the detection of potassium ions in the entire physiologically relevant range (1 to 500 mM) with a fast response time, unaffected by the presence of main interfering ions and sweat-collecting materials. A kidney-shaped interdigitated LIG electrode enabled the determination of the overall electrolyte concentration by electrochemical impedance spectroscopy at a fixed frequency. Enzyme-based strategies with amperometric detection share a common RE and were realized with Prussian blue as electron mediator and biocompatible chitosan for enzyme immobilization and protection of the electrode. Using glucose and lactate oxidases, lower limits of detection of 13.7 ± 0.5 μM for glucose and 28 ± 3 μM for lactate were obtained, respectively. The sensor showed a good performance at different pH, with sweat-collecting tissues, on a model skin system and furthermore in synthetic sweat as well as in artificial tear fluid. Response time for each analytical cycle totals 75 s, and hence allows a quasi-continuous and simultaneous monitoring of all analytes. This multi-analyte all-LIG system is therefore a practical, versatile, and most simple strategy for point-of-care applications and has the potential to outcompete standard screen-printed electrodes.
Home visits by a cardiac nurse clinician and patients diagnosed with heart failure

description: Heart failure (HF) is a debilitating syndrome affecting thousands of Canadians every year. It is one of the leading causes of death in Canada and has been found to be the leading cause of readmission to hospital in North America. We sought to determine if home visits by a cardiac nurse clinician reduced heart failure readmissions to hospital in Canada. A retrospective cohort study design examined the effect of an existing post-discharge home visit intervention program for patients with heart failure. The study sample consisted of 215 patients, each hospitalized with a “most responsible inpatient diagnosis of heart failure.” Between 2011 and 2013, 103 patients were referred to the home visit intervention program and seen by the cardiac nurse clinician at home. The usual care group 112 patients was randomly extracted from Discharge Abstract Database between 2009 and 2011. Meleis’ Transitions Theory informed and guided the study, and Wagner’s Chronic Care Model guided the intervention. The main outcome measure was 30-day hospital readmissions for heart failure. The intervention group had fewer readmissions to hospital for heart failure and a higher number of referrals to cardiac rehabilitation than usual care group (p ≤ 0.001). No significant differences were found between all-cause readmissions, length of stay of readmissions, or all-cause emergency visits between the two groups. Our results suggest that there may be a relationship between home visits by a cardiac nurse clinician and heart failure readmissions with patients who are diagnosed with heart failure. Furthermore, we believe the model may be beneficial for treatment of other cardiac patients. There may be a cost saving for the healthcare system in reducing heart failure readmissions to hospital; however, we recognize that a proper cost analysis is needed to confirm the economic benefits of the model. More work is needed in testing this intervention in other geographic areas (e.g., rural), as well as with patients who have different socioeconomic characteristics. A more rigorous study design, such as a randomized controlled trial or interrupted time series, is needed to further test the model of home visits with those patients who suffer from heart failure.
