Emergency Room Visit Prevention for Older Patients with Parkinsonism in a Geriatric Clinic
Authors: Lee Joyce W. , Mah Greta , Kalia Sumeet , Miyasaki Janis 
Published: November 2020

ABSTRACT:Background:Older persons with parkinsonism (PWP) are at high risk for hospitalization and adverse outcomes. Few effective strategies exist to prevent Emergency Department (ED) visits and hospitalization. The interdisciplinary Geriatrics Clinic for Parkinson’s (“our clinic”) was founded to address the complexity of parkinsonism in older patients, supported by a pharmacist-led telephone intervention (TI) service. Our primary objective was to study whether TI could avert ED visits in older PWP.Methods:Using a prospective, observational cohort, we collected data from all calls in 2016, including who initiated and reasons for the calls, patient demographics, number of comorbidities and medications, diagnoses, duration of disease, and intervention provided. Calls with intention to visit ED were classified as “crisis calls”. Outcome of whether patients visited ED was collected within 1 week, and user satisfaction by anonymous survey within 3 weeks.Results:We received 337 calls concerning 114 patients, of which 82 (24%) were “crisis calls”. Eighty-one percent of calls were initiated by caregivers. Ninety-three percent of “crisis calls” resolved without ED visit after TI. The main reasons for “crisis calls” were non-motor symptoms (NMS) (39%), adverse drug effects (ADE) (29%), and motor symptoms (18%). Ninety-seven percent of callers were satisfied with the TI.Conclusion:Pharmacist-led TI in a Geriatrics Clinic for Parkinson’s was effective in preventing ED visits in a population of older PWP, with high user satisfaction. Most calls were initiated by caregivers. Main reasons for crisis calls were NMS and ADE. These factors should be considered in care planning for older PWP.
Kneading sequences for toy models of Hénon maps
Authors: ARAUJO ERMERSON 
Published: November 2020

AbstractThe purpose of this article is to study the relation between combinatorial equivalence and topological conjugacy, specifically how a certain type of combinatorial equivalence implies topological conjugacy. We introduce the concept of kneading sequences for a setting that is more general than one-dimensional dynamics: for the two-dimensional toy model family of Hénon maps introduced by Benedicks and Carleson, we define kneading sequences for their critical lines, and prove that these sequences are a complete invariant for a natural conjugacy class among the toy model family. We also establish a version of Singer’s theorem for the toy model family.
Motivic Steenrod operations in characteristicp
Authors: Primozic Eric 
Published: November 2020

AbstractFor a primepand a fieldkof characteristic$p,$we define Steenrod operations$P^{n}_{k}$on motivic cohomology with$\mathbb {F}_{p}$-coefficients of smooth varieties defined over the base field$k.$We show that$P^{n}_{k}$is thepth power on$H^{2n,n}(-,\mathbb {F}_{p}) \cong CH^{n}(-)/p$and prove an instability result for the operations. Restricted to modpChow groups, we show that the operations satisfy the expected Adem relations and Cartan formula. Using these new operations, we remove previous restrictions on the characteristic of the base field for Rost’s degree formula. Over a base field of characteristic$2,$we obtain new results on quadratic forms.
Profinite invariants of arithmetic groups
Authors: Kammeyer Holger , Kionke Steffen , Raimbault Jean , Sauer Roman 
Published: November 2020

AbstractWe prove that the sign of the Euler characteristic of arithmetic groups with the congruence subgroup property is determined by the profinite completion. In contrast, we construct examples showing that this is not true for the Euler characteristic itself and that the sign of the Euler characteristic is not profinite among general residually finite groups of typeF. Our methods imply similar results for$\ell^2$-torsion as well as a strong profiniteness statement for Novikov–Shubin invariants.
‘A Perfectly Self-Contained Tetralogy’: Mahler’s Tragicomic Inspirations
Authors: BATSTONE LEAH 
Published: November 2020

AbstractThis article examines Mahler’s Fourth Symphony and its role in what the composer called his ‘perfectly self-contained tetralogy’. Previous explanations for this phrase include the first four symphonies’ shared song quotations and ideological content, but the dramas of ancient Dionysian festivals present a better model: three serious tragedies and a comic satyr play, a performance grouping also known as a ‘tetralogy’. Following Mahler’s first three symphonies (his ‘Trilogie der Leidenschaft’), the Fourth Symphony – originally entitled ‘Humoreske’ – is compared to a light-hearted satyr play, featuring abrupt juxtapositions of moods and a setting of the humorous song ‘Das himmlische Leben’. Praise for the redemptive effects of this ancient tragicomic juxtaposition plays an important role in Nietzsche’s The Birth of Tragedy, and the importance of humour especially shaped the philosopher’s later writings, many of which Mahler knew from his time as a student in Vienna. This new reading not only provides a better explanation for Mahler’s comment, but also illustrates Nietzsche’s influence on the composer’s sense of drama.
Amateur Recording on the Phonograph inFin-de-siècleBarcelona: Practices, Repertoires and Performers in the Regordosa-Turull Wax Cylinder Collection
Authors: MOREDA RODRÍGUEZ EVA 
Published: November 2020

AbstractThe Regordosa-Turull wax cylinder collection, held at the Biblioteca de Catalunya, Barcelona, is unique among early recording collections. It contains 358 cylinders recorded by the textile industrialist Ruperto Regordosa, mostly at his Barcelona home, featuring prominent Spanish and non-Spanish singers of opera and zarzuela, as well as the composer Isaac Albéniz. This article aims to establish the significance of the collection for the study both of the amateur recording culture that existed alongside commercial phonograph recordings and of performance practices in opera and zarzuela. By examining the broader characteristics of the collection and textual sources from the period, and by closely analysing some of the cylinders, this article explores how Regordosa adopted (and in some cases adapted) certain generic conventions employed in commercial recordings of the time, and what the implications of this are when considering these early recordings as documents of performance practice.

Published: November 2020

AbstractMammary tissue (MT) turnover is characterized by programed cell death and remodeling which might be affected by both feeding level and animal species. Thus, twenty-four dairy goats and the same number of sheep were assigned to three homogenous sub-groups per animal species and fed the same diet in quantities which met 70% (FL70), 100% (FL100) and 130% (FL130) of their daily energy and crude protein requirements. Individual MT samples were taken by biopsy from the animals on the 30th and 60th experimental day. The results showed, in the first sampling time, a significant reduction in the mRNA abundance for selected genes involved in programed cell death in both FL 70 fed goats (STAT3 and BECN1) and sheep (CASPASE8 and BECN1) compared with the respective FL100 groups. The FL130, in comparison with the FL100, caused a significant increase in transcripts accumulation of STAT3 gene in both sampling times and CASPASE8 gene in the second sampling time in goat MT, while the opposite happened for the mRNA expression of CASPASE8 and BECN1 genes in sheep MT, but only in the first sampling time. Moreover, a significant up regulation in the mRNA levels of MMP2 gene in MT of FL130 fed sheep was observed. The FL130, in comparison with the FL70, caused an enhancement in the mRNA expression levels of BECN1, CASPASE8, BAX and STAT3 genes in goat MT only. It was also shown that apoptosis and autophagy can be affected simultaneously by the feeding level. Overfeeding affects MT programed cell death and remodeling by a completely different way in goats than sheep. In conclusion, feeding level and animal species have strong effects on both MT programed cell death (apoptosis and autophagy) and remodeling but the molecular mechanisms need further investigation.
An ecological study of objective rest–activity markers of lithium response in bipolar-I-disorder
Authors: Scott Jan , Hennion Vincent , Meyrel Manon , Bellivier Frank , Etain Bruno 
Published: November 2020

AbstractBackgroundDespite its pivotal role in prophylaxis for bipolar-I-disorders (BD-I), variability in lithium (Li) response is poorly understood and only a third of patients show a good outcome. Converging research strands indicate that rest–activity rhythms can help characterize BD-I and might differentiate good responders (GR) and non-responders (NR).MethodsSeventy outpatients with BD-I receiving Li prophylaxis were categorized as GR or NR according to the ratings on the retrospective assessment of response to lithium scale (Alda scale). Participants undertook 21 consecutive days of actigraphy monitoring of sleep quantity (SQ), sleep variability (SV) and circadian rhythmicity (CR).ResultsTwenty-five individuals were categorized as GR (36%). After correcting statistical analysis to minimize false discoveries, four variables (intra-daily variability; median activity level; amplitude; and relative amplitude of activity) significantly differentiated GR from NR. The odds of being classified as a GR case were greatest for individuals showing more regular/stable CR (1.41; 95% confidence interval (CI) 1.08, 2.05;p< 0.04). Also, there was a trend for lower SV to be associated with GR (odds ratio: 0.56; 95% CI 0.31, 1.01;p< 0.06).ConclusionsTo our knowledge, this is the largest actigraphy study of rest–activity rhythms and Li response. Circadian markers associated with fragmentation, variability, amount and/or amplitude of day and night-time activity best-identified GR. However, associations were modest and future research must determine whether these objectively measured parameters, singly or together, represent robust treatment response biomarkers. Actigraphy may offer an adjunct to multi-platform approaches aimed at developing personalized treatments or stratification of individuals with BD-I into treatment-relevant subgroups.
‘I'm old, but I'm not old-fashioned’: mealtimes and cooking practices among Danish widows and widowers
Authors: Andersen Sidse Schoubye 
Published: November 2020

AbstractExisting research on how older adults handle challenges associated with domestic housework, and in particular food work, almost invariably assumes that older adults are traditionalist, and that this affects the way they adjust to widowhood. This assumption is problematic, as decades of research have emphasised increasing gender equality in food work. In this paper, I explore how older adult men and women adjust to food preparation after the loss of a spouse. Interviews with 31 Danish widows and widowers aged between 67 and 86 years old suggest that the men have made culinary progress. However, I also show that the narratives around domestic food work among the older generations remain gendered: both men and women identify widowed men's domestic food work as something meriting acknowledgement, and men and women draw on traditional masculine and feminine ways of approaching domestic food work.
ANOTHER CASE OF THE MIDDLE-INCOME TRAP: CHILE, 1900–1939
Authors: Couyoumdjian Juan Pablo , Larroulet Cristián , Díaz Diego A. 
Published: November 2020

ABSTRACTThis paper studies the evolution of the Chilean economy in the late 19th and early 20th century, a period when the country's convergence with developed countries came to an end. We analyse this problem in the context of the modern literature on the middle-income trap. The social, political and economic history of Chile between 1875 and 1939 is examined and the presence of most of the factors associated with the middle-income trap is found. We complement this narrative through a quantitative analysis based on the synthetic control method and argue that the process of state-led industrialisation undertaken in the country leading to the formation of CORFO was a key economic and political event. Our work presents some general lessons for developing countries facing a similar context.
THE ABSOLUTION OF HISTORY: CUBAN LIVING STANDARDS AFTER 60 YEARS OF REVOLUTIONARY RULE
Authors: Devereux John 
Published: November 2020

ABSTRACTSix decades ago, Cuba initiated a momentous social and economic experiment. This paper documents the effects of the experiment on Cuban living standards. Before the revolution, Cuban income per capita was on a par with Ireland or Finland. Indeed, Cuba was one of the richest of the Spanish-speaking societies. Growth is glacially slow after the revolution as GDP per capita increased by 40 per cent between 1957 and 2017 equal to an annual growth rate of 0.6 per cent—among the lowest anywhere. To be sure, other dimensions of well-being such as education and health improved, yet broader welfare measures do not change the conclusion that the revolution impoverished Cuba relative to any plausible counter factual.
Chasing the ghost of infection past: identifying thresholds of change during the COVID-19 infection in Spain
Authors: Santamaría Luis , Hortal Joaquín 
Published: November 2020

AbstractOne of the largest nationwide bursts of the first COVID-19 outbreak occurred in Spain, where infection expanded in densely populated areas through March 2020. We analyse the cumulative growth curves of reported cases and deaths in all Spain and two highly populated regions, Madrid and Catalonia, identifying changes and sudden shifts in their exponential growth rate through segmented Poisson regressions. We associate these breakpoints with a timeline of key events and containment measures, and data on policy stringency and citizen mobility. Results were largely consistent for infections and deaths in all territories, showing four major shifts involving 19–71% reductions in growth rates originating from infections before 3 March and on 5–8, 10–12 and 14–18 March, but no identifiable effect of the strengthened lockdown of 29–30 March. Changes in stringency and mobility were only associated to the latter two shifts, evidencing an early deceleration in COVID-19 spread associated to personal hygiene and social distancing recommendations, followed by a stronger decrease when lockdown was enforced, leading to the contention of the outbreak by mid-April. This highlights the importance of combining public health communication strategies and hard confinement measures to contain epidemics.
School lunch nutritional adequacy: what is served, consumed and wasted
Authors: Liz Martins Margarida , Rodrigues Sara SP , Cunha Luís M , Rocha Ada 
Published: November 2020

AbstractObjective:To determine nutritional adequacy of school lunch and to assess the impact of food waste on nutrient intake of primary schoolchildren.Design:The weighing method was used for evaluating initial servings and plate waste for lunch. Energy and nutritional contents of meals served, consumed and wasted were estimated using the software Food Processor Plus. The mean nutritional value of food served and consumed was compared with dietary guidelines.Setting:Portuguese public primary schools in the city of Porto.Participants:All 525 fourth-grade children, aged from 9 to 10 years old, attending to twenty-one public primary schools.Results:Overall, school lunches served did not meet the dietary guidelines for energy and nutrients, as only 12·5 % of the evaluated meals were adequate for energy, 33·5 % for proteins, 11·9 % for carbohydrates and 57·1 % for lipids. The majority of meals served were below the age-specific lower limit, namely for energy (83·7 %) and carbohydrates (86·8 %). The only exception, also unbalanced, was observed for proteins, as 42·4 % of lunches served exceeded the recommended upper limit. Furthermore, lunches served and consumed by children did not meet the dietary guidelines for fibre and for the micronutrients evaluated. Children wasted 26 % of the energy content provided in lunches, corresponding to 91·5 kcal, 25 % of proteins and 29 % of carbohydrates supplied.Conclusions:The lunches served and consumed by children at school canteens failed to meet nutritional standards. These results are not only a consequence of inadequate food portions served but also a result of the high plate waste values observed.
Spectrums of depositional practice in later prehistoric Britain and beyond. Grave goods, hoards and deposits ‘in between’
Authors: Cooper Anwen , Garrow Duncan , Gibson Catriona 
Published: November 2020

AbstractThis paper critically evaluates how archaeologists define ‘grave goods’ in relation to the full spectrum of depositional contexts available to people in the past, including hoards, rivers and other ‘special’ deposits. Developing the argument that variations in artefact deposition over time and space can only be understood if different ‘types’ of find location are considered together holistically, we contend that it is also vital to look at the points where traditionally defined contexts of deposition become blurred into one another. In this paper, we investigate one particular such category – body-less object deposits at funerary sites – in later prehistoric Britain. This category of evidence has never previously been analysed collectively, let alone over the extended time period considered here. On the basis of a substantial body of evidence collected as part of a nationwide survey, we demonstrate that body-less object deposits were a significant component of funerary sites during later prehistory. Consequently, we go on to question whether human remains were actually always a necessary element of funerary deposits for prehistoric people, suggesting that the absence of human bone could be a positive attribute rather than simply a negative outcome of taphonomic processes. We also argue that modern, fixed depositional categories sometimes serve to mask a full understanding of the complex realities of past practice and ask whether it might be productive in some instances to move beyond interpretively confining terms such as ‘grave’, ‘hoard’ and ‘cenotaph’. Our research demonstrates that is it not only interesting in itself to scrutinize archaeological evidence that does not easily fit into traditional narratives, but that the process of doing so also sheds new light on the validity of our present-day categories, enabling deeper insights into how people in the past ordered their material and conceptual worlds. Whilst our main focus is later prehistoric Britain, the issues we consider are potentially relevant across all periods and regions.

Abstract

Aims
Coronavirus disease 2019 (COVID-19) pandemic is a major public health concern all over the world. Little is known about the impact of COVID-19 pandemic on mental health in the general population. This study aimed to assess the mental health problems and associated factors among a large sample of college students during the COVID-19 outbreak in China.

Methods
This cross-sectional and nation-wide survey of college students was conducted in China from 3 to 10 February 2020. A self-administered questionnaire was used to assess psychosocial factors, COVID-19 epidemic related factors and mental health problems. Acute stress, depressive and anxiety symptoms were measured by the Chinese versions of the impact of event scale-6, Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7, respectively. Univariate and hierarchical logistic regression analyses were performed to examine factors associated with mental health problems.

Results
Among 821 218 students who participated in the survey, 746 217 (90.9%) were included for the analysis. In total, 414 604 (55.6%) of the students were female. About 45% of the participants had mental health problems. The prevalence rates of probable acute stress, depressive and anxiety symptoms were 34.9%, 21.1% and 11.0%, respectively. COVID-19 epidemic factors that were associated with increased risk of mental health problems were having relatives or friends being infected (adjusted odds ratio = 1.72–2.33). Students with exposure to media coverage of the COVID-19 ≥3 h/day were 2.13 times more likely than students with media exposure <1 h/day to have acute stress symptoms. Individuals with low perceived social support were 4.84–5.98 times more likely than individuals with high perceived social support to have anxiety and depressive symptoms. In addition, senior year and prior mental health problems were also significantly associated with anxiety or/and depressive symptoms.

Conclusions
In this large-scale survey of college students in China, acute stress, anxiety and depressive symptoms are prevalent during the COVID-19 pandemic. Multiple epidemic and psychosocial factors, such as family members being infected, massive media exposure, low social support, senior year and prior mental health problems were associated with increased risk of mental health problems. Psychosocial support and mental health services should be provided to those students at risk.

AbstractDNA origami, in which a long scaffold strand is assembled with a many short staple strands into parallel arrays of double helices, has proven a powerful method for custom nanofabrication. However, currently the design and optimization of custom 3D DNA-origami shapes is a barrier to rapid application to new areas. Here we introduce a modular barrel architecture, and demonstrate hierarchical assembly of a 100 megadalton DNA-origami barrel of ~90 nm diameter and ~250 nm height, that provides a rhombic-lattice canvas of a thousand pixels each, with pitch of ~8 nm, on its inner and outer surfaces. Complex patterns rendered on these surfaces were resolved using up to twelve rounds of Exchange-PAINT super-resolution microscopy. We envision these structures as versatile nanoscale pegboards for applications requiring complex 3D arrangements of matter, which will serve to promote rapid uptake of this technology in diverse fields beyond specialist groups working in DNA nanotechnology.
