The Use of Social Media in Searching for Information about Papua
Authors: Cobaaaa Cobaaa
Published: March 2021

The use of social media in searching for information relating to conflict and political issues has become immensely crucial since in those domains the information appearing is often biased and dominated by certain parties or groups. One of the political information that has frequently emerged in Indonesia is about Papua. Papua is the longest problem in the history of Indonesia and that conversation has continued, especially in social media in the last three years.This study intends to examine the use of social media in searching for information about Papua. The Uses and Gratification Theory (UGT) is used in the study with a mixed method approach as both quantitative and qualitative data were concurrently utilized. Quantitative data obtained from a questionnaire distributed to 100 UPN "Veteran" students in Yogyakarta. While qualitative data from in-depth interviews with some sources. In conclusion, social media cannot be used as the only media for seeking information about Papua. Social media has a set of limitations requiring the audience to employ other means including face-to-face meetings through discussions. This is in line with UGT, which states that audiences actively choose the media based on their motivation, experience, and satisfaction.

Published: March 2021

Mental health is currently a health that must be considered in addition to physical health. According to Riset Kesehatan Dasar (2018), it shows that depression is the highest mental illness and there are 450,000 people who are people with severe mental disorders (ODGJ) who have an age range of 15-29 years. This study aims to see the communication made by survivor of mental health disorders in creating millennials to their closest people. The theory used in this research is Communication Privacy Management Theory (CPM) and Contructivism Theory. CPM theory explains how a person with a health disorder communicates mental illness by considering their personal information. Meanwhile, constructivism theory supports the CPM theory to explain how sufferers of mental health disorders choose the right diction so as not to cause wrong perceptions. Constructivism theory explains how a person constructs the message to be delivered. The method used in this study is a qualitative method with purposive sampling, which is to determine the information required by the researcher. The results of this study are each information that has rules for conveying privacy information to the closest person. The informants' trust with other people still have their privacy boundaries made based on gender, culture and context. In addition, informants used proper diction to convey their mental illness to the closest people.

As a night tourist destination that is unique and has great potential, Puncak Sosok requires an evaluation of Puncak Sosok's marketing communications. The formulation of the problem in this research is how to evaluate marketing communication conducted by Puncak Sosok managers. The purpose of this research is to describe and to find out the evaluation of Puncak Sosok marketing communication and the supporting and inhibiting factors in its implementation. This research uses eight main marketing communication models by Kotler and the PII (Preparation, Implementation, Impact) evaluation model by Cutlip-Center-Broom with a qualitative approach. The results of the evaluation on the preparation aspect are conformity with the objectives and background where fluctuations in visits, but there are no details number of the tourist targets so that the measurement of success is not detailed. Evaluation on the implementation aspect are that most of the programs have been running well, but there are problems such as social media creativity and the absence of tour packages and authentic Puncak Sosok products. Impact evaluation results on most programs have had a positive impact such as the number of media publications and known as a typical night tourism destination with live music. Nevertheless, some programs are still ineffective and need to be improved, such as direct marketing and personal selling programs, which have less impact on attracting tourists. Supporting factors are the relationship that exists with the media and stakeholders, while the lack of innovation and knowledge of human resources in marketing and media use become inhibiting factors.

Bases de datos de mujeres expertas: escenario global y situación en España
Authors: Campos-Rueda Marcela , Herrera-Damas Susana
Published: March 2021

This paper examines databases of female experts as tools to promote gender parity in the sources consulted and cited by journalists. To do this, we conducted a search of databases available online (n = 88) and carried out in-depth interviews with people in charge of these databases (n = 4) as well as a survey among female scientific researchers included in the database of the Association of Women Researchers and Technologists of Spain (AMIT) (n = 919). The main results reflect the great potential of these tools but indicate that, to be effective, they require fluid communication with the media and a design that allows their incorporation into the regular routines of journalists. In Spain, their impact is still low and, as in the rest of the world, there is great fragmentation of resources accompanied by very weak interaction among the different initiatives.

Resumen
Se presenta un análisis de las bases de datos de mujeres expertas como herramientas para fomentar la paridad de género en las fuentes que consultan y citan los periodistas. Para informar nuestro trabajo, hemos llevado a cabo una búsqueda de las bases de datos disponibles online (n=88). En un segundo momento, la completamos con la realización de entrevistas en profundidad con las directivas al frente de estas bases (n=4) y con la realización de una encuesta a expertas científicas que participan de la base de datos de la Asociación de Mujeres Investigadoras y Tecnólogas de España (AMIT) (n=919). Los principales resultados reflejan el alto potencial de estas herramientas e indican que, para que resulten eficaces a la hora de sumar diversidad en la selección de fuentes expertas, requieren una comunicación fluida con los medios y un diseño que permita incorporarlas a las rutinas habituales de los periodistas. En España su impacto aún es bajo y, al igual que ocurre a nivel global, se aprecia una alta fragmentación de los recursos junto a un nivel casi nulo de interacción entre las distintas iniciativas.

Analysis of composition and dispersion of fuel emulsions
Authors: Melnyk V. O.
Published: March 2021

The development of the economy of the state, as well as industrial enterprises, leads to an increase in demand for all types of energy carriers. This is characterized by the constant search and exploration of new progressive types of energy and sources of raw materials, especially for thermal power plant TPPs, CHPs and utilities, which use liquid fuel - usually fuel oil - to operate. For such enterprises, stable and timely supply of fuel raw materials, improvement of methods of its combustion, reduction in the cost of obtaining energy, etc. are relevant. Existing heavy hydrocarbon combustion technologies are of poor quality and it is therefore advisable to develop new ones or to optimize existing ones. This will reduce energy costs for technological preparatory operations for the de-watering of fuels, reduce the amount of polluted water reservoirs, and minimize their harmful effects on the envi-ronment. One of the most promising areas for combustion of heavy water hydrocarbons is the use of water emulsion fuels (WEF). The stability and efficiency of combustion of such a fuel emulsion will greatly depend on the amount and dispersion of water in the WEF. Today, such emulsification technologies and WEF parameters are not yet well understood and are therefore of great scientific and practical importance. The analysis of the theories describing the effect of dispersion and the amount of water in the emulsion on the combustion indices shows that they are contradictory. This can be due to the different physical characteristics of the fuel: composition, viscosity, temperature, etc., which has led to different results. Since studies by different authors were conducted under dif-ferent conditions, modes, equipment and with different fuel emulsions, it is not possible to indicate the optimum value of dispersion and amount of water. Obviously, in each case there will be a different optimal "surface" of the ratio of the size of the droplets of water and its number in the WEF. Future experimental and theoretical studies on the combustion of WEF should focus on the water content range of 3-30% and the dispersion of 1-35 microns.

What can ethnography offer: methodological reflections and case studies
Authors: Fleming K. , Smagulova J. , Tleuov A.
Published: March 2021

This paper discusses the advantages and challenges of ethnography as a research method, especially as applied to the study of language in complex multilingual contexts. In this paper, we briefly outline the theoretical and methodological foundations of ethnography, and then we reflect on our own experiences as researchers making use of this method in two different contexts — Hong Kong (Fleming) and Kazakhstan (Smagulova). We conclude by suggesting possible benefits of ethnography and ethnographically-informed approaches in relation to the study of language and education in Kazakhstan. The authors of this article specialize in the fields of language, society, and education; accordingly, the insights we offer might be of particular interest for scholars doing research in similar domains. However, we do acknowledge that the potential of the methodological application of ethnography transcends language studies. Indeed, ethnographic methods have contributed substantially to knowledge production across various academic disciplines. The strength of ethnography as a method, we believe, lies in its capacity to generate rich, deep, and context-sensitive data whether used separately or together with other approaches in multi-dimensional studies. Kazakhstan is a context where relatively few ethnographic studies have taken place, and which might benefit greatly from further studies of this type.

The article considers the place of Abay's poems in modern Kazakh artistic texts. Each author conveys his worldview and worldview in different situations through an artistic text. His lexicon includes, along with various means of the national language, fragments of various texts known to varying degrees in a certain linguistic and cultural community, as well as the word use of poets and writers who lived and worked before him. Such fragments may be used without change or А.С. Əділова, Б.С. Каукербекова 12 Вестник Карагандинского университета with a transformation. In the Kazakh linguistic and cultural community, Abay's poems can be called strong literary texts with a high frequency of use. Quotation at the level of structure, word, phrase, sentence, whole text can be seen in poetic and prose texts of the last 60–70 years in the Kazakh literary process. In this regard, the texts of such writers as M. Makataev, M. Magauin, J. Abdrashev, G. Zhailybai, G. Sаlykbai, M. Raiymbek, J. Sarsek are immediately recalled. Pointing out that this trend continues by young poets engaged in creativity in the last decades of this, XXI century, the authors concludes that the legacy of Abay is a standard of verbal art for more generations of poets and writers.

Panorama: O mecanismo da evacuação ocorre através da combinação de movimentos reflexos e voluntários. A alteração funcional nesses mecanismos pode levar à constipação intestinal. Objetivo: Fornecer evidências empíricas a respeito da possível relação entre a falha no relaxamento da musculatura do assoalho pélvico com a constipação intestinal. Método: voluntárias maiores de 18 anos respondem o questionário de ROMA III e a Escala de Bristol para Consistência de Fezes, além de uma avaliação funcional do assoalho pélvico onde foram avaliadas a coordenação, força, potência, endurance e atividade automática dos músculos do assoalho pélvico durante a contração e o relaxamento. Teste exato de Fisher foi utilizado para relacionar constipação à falha no relaxamento. Resultados: 50 mulheres com idades entre 18 e 63 anos atenderam ao estudo, sendo que 84% apresentaram ausência ou falha no relaxamento do assoalho pélvico, dessas, 85,7% foram consideras constipadas. Dentre as mulheres que apresentaram relaxamento completo, 50% foram consideradas constipadas. Conclusão: A falha no relaxamento da musculatura do assoalho pélvico pareceu relacionada à constipação intestinal, e fatores socioculturais podem explicar a hiperatividade do assoalho pélvico, caracterizada por falha no relaxamento, responsável pela epidemia de constipação funcional em mulheres.

Published: March 2021

O objetivo do presente estudo foi verificar o efeito da aplicação de diferentes percentuais da velocidade crítica (VC) no consumo de oxigênio (VO2), no esforço percebido (EP) e na frequência média de ciclos de passadas (FP) em teste incremental de caminhada. Oito indivíduos, do sexo masculino, realizaram testes máximos com durações de seis e nove minutos, para a determinação da VC. Posteriormente, os sujeitos realizaram teste incremental em percentuais da VC: cinco velocidades de seis minutos de duração cada, nos percentuais de 75, 80, 85, 90 e 100% da VC. Os resultados mostraram que os valores de velocidade de caminhada (Vcam) e EP apresentaram diferenças significativas nos percentuais de 75%, 80%, 85%, 90% e 100% da VC (p < 0,05). As demais variáveis de FP e de VO2 não apresentaram diferença significativa, somente entre os percentuais de 85% (FP = 70,22 ± 3,04 ciclos.min-1 e VO2 = 23,81 ± 4,82 ml?kg-1?min-1) e 90% (FP = 73,67 ± 4,91 ciclos.min-1 e de VO2 = 26,92 ± 4,50 ml?kg-1?min-1) da VC (p < 0,05). Os valores de EP aumentaram conforme o aumento dos percentuais da VC. A FP e o VO2 não apresentaram diferença significativa entre os percentuais de 85 e 90% da VC, o que pode representar uma mesma zona de resposta fisiológica. Assim, os percentuais da VC determinados, nas respectivas velocidades acima do ritmo autosselecionado na caminhada podem ser utilizados de uma maneira eficaz para o controle do treinamento.

Published: March 2021

O objetivo do presente estudo foi analisar um projeto de extensão universitária em atividade desde 2006 e cujo intuito reside no oferecimento de atividades circenses para crianças de 6 a 12 anos nas dependências de uma Universidade pública brasileira no interior do estado de São Paulo. Considerando que se trata de um projeto consolidado, em curso há mais de 10 anos, foi realizada pesquisa qualitativa, por meio de observações de campo durante um semestre de atividades (16 encontros) e entrevistas semiestruturadas com os monitores e com o coordenador do projeto. Os resultados apontam aulas ministrados por educadores em formação acadêmica (graduados e pós-graduandos em Educação Física) sendo suplantados por um coletivo de estudiosos do Circo (artistas, historiadores, pedagogos), atividades e ações pedagógicas orientadas por uma diversidade de fontes de conhecimentos e (re)ações discentes em acordo com as proposições educativas do projeto. A ludicidade dos jogos e brincadeiras, a aceitação das diferenças e o contato com a diversidade de práticas circenses atreladas à expressividade, criatividade e criticidade foram elementos que permearam o projeto e configuram-se em princípios a serem extrapolados (adaptados e/ou inspiradores) para outras iniciativas com a pedagogia das atividades circenses. Por fim, ressaltamos, a partir dos resultados observados e das proposições apresentadas, que a desejada composição arte circense/Educação Física escolar dá azo ao tensionamento de uma educação demasiada informativa, opinativa e imediatista. De resto, vale a menção de que está em jogo o desafio aos professores de Educação Física por engendrar gretas para a temática circense em suas propostas curriculares.

Published: March 2021

Vários métodos de aquecimento têm sido empregados no campo do treinamento esportivo. O foam rolling (FR) é uma das técnicas mais populares. No entanto, permanece o esclarecimento sobre os períodos ótimos de FR para melhorar ou manter o desempenho. Portanto, o objetivo do presente estudo foi explorar o efeito agudo de diferentes períodos do FR no desempenho do salto vertical contramovimento (SV). Doze indivíduos recreacionalmente ativos (23,92 ± 4,08 anos, 70 ± 12 kg, 171 ± 8cm) foram voluntários para o estudo. Os participantes realizaram seis visitas separadas por 48 horas. A primeira sessão incluiu a coleta de dados antropométricos, familiarização com o FR e a técnica do SV. Em seguida, cinco protocolos experimentais foram executados em ordem aleatória: Protocolo controle (CP) - salto vertical sem FR; P30 – uma série de 30 segundos de FR antes do salto vertical; P60 - duas séries de 30 segundos de FR; P90: três séries de 30 segundos de FR; P120 – quatro séries de 30 segundos de FR. O FR foi implementado para quadríceps, isquiotibiais, glúteo e gastrocnêmio. Diferenças significativas no desempenho do salto vertical (p

Introdução: A utilização de métodos específicos de mensuração é de fundamental importância para a identificação da capacidade aeróbia e prescrição da intensidade de exercício. Normalmente esta definição é feita pela determinação do limiar anaeróbio (Lan) que corresponde à máxima fase estável entre produção e remoção de lactato sanguíneo (MFEL). Dentre as mais variadas formas de se determinar a MFEL estão os testes de lactato mínimo (LM) e carga crítica (CC). No entanto, não se sabe se a utilização dessas formas de avaliação podem acarretar em resultados distintos. Objetivo: O objetivo do presente estudo foi comparar os valores de Lan obtidos por meio dos testes de CC e de LM em ratos Wistar. Método: Foram utilizados 32 ratos machos (Wistar), com peso médio 411,0 (± 40,7 gramas), os quais foram submetidos às baterias de testes de CC e de LM. O teste de LM foi realizado com a indução à hiperlactacidemia com dois estímulos correspondentes a 13% do peso corporal (PC), seguido de intervalo passivo de nove minutos e teste incremental composto por estágios com duração de cinco minutos e cargas equivalentes a 4.0, 4.5, 5.0, 5.5, 6.0 e 7.0 % do PC. Já a CC foi obtida por meio da indução ao exercício em quatro diferentes estímulos randomizados, com cargas correspondentes a 7, 9, 11 e 13% do PC. Resultados: Os resultados demonstraram que o Lan médio determinado pelo Teste de CC foi de 5,8 ± 1,2% do peso corporal (PC) e 4,9 ± 0,6% do PC determinado pelo Teste de LM. Conclusão: Pode–se concluir que o limiar anaeróbio determinado por meio do teste CC superestimou em 18,4% o valor obtido por meio do teste de LM.

Published: March 2021

O diabetes mellitus tipo 2 (DM2) é uma doença crônico-degenerativa não transmissível, caracterizada pela hiperglicemia que acomete cada vez mais a população idosa, principalmente, devido ao estilo de vida. Os sintomas da doença envolvem algumas complicações fisiológicas, dentre elas existe a possibilidade de desenvolvimento da neuropatia autonômica cardiovascular, que comumente acomete o diabético com a diminuição da variabilidade da frequência cardíaca (VFC). Levando assim, a uma insuficiência cardíaca que pode comprometer de forma severa a vida do diabético. Sendo assim, o objetivo foi analisar o efeito crônico da prática do exercício físico em idosas com DM2 baseado nos parâmetros da VFC. Para que a pesquisa fosse realizada um grupo de 30 idosas foi selecionado aleatoriamente, sendo divididos em três grupos de 10 voluntárias: grupo diabético ativo (GDA), grupo diabético sedentário (GDS) e grupo controle (GC), para ambos os grupos foram coletados as seguintes variáveis: idade, estatura, massa corporal, IMC, gordura corporal relativa e VFC. Os resultados demonstraram que idosas GDA (870,6 ± 55,3 ms) tiveram uma menor média do intervalo RR e pode demonstrar que com a pratica regular de atividade física é possível retardar e/ou evitar quando comparado ao GC (788,4 ± 27,7 ms) as possíveis complicações cardíacas que acometem ao GDS (874,3 ± 45,7 ms). Diante do exposto acredita-se que o exercício físico foi determinante para o resultado encontrado na VFC, principalmente, a média do intervalo RR no que tange estratificar idosas que possuem diabete tipo 2.

Objetivos: Comparar os efeitos do treino com restrição de fluxo sanguíneo com o treino resistido de alta intensidade no ganho de força e hipertrofia. Material e Métodos: Neste ensaio clínico randomizado e controlado, 24 homens sedentários foram randomizados em dois grupos: treino com restrição de fluxo sanguíneo ou treino resistido de alta intensidade. Ambos os grupos realizaram 10 sessões de exercício de preensão manual até com 3 séries de exercícios até a falha, sendo que o grupo com treino de restrição de fluxo sanguíneo realizou com 30% da carga máxima obtida no teste de 1 repetição máxima, enquanto que o grupo de alta intensidade realizou com 80% da carga. Todos os voluntários foram avaliados e reavaliados a dinamometria de preensão manual e a perimetria de antebraço. Os dados foram tabulados e analisados no statistical package for the social sciences, utilizando o teste T-student, e o não paramétrico U de Mann Whitney, adotando a significância de 5% (? = 0,05). Resultados: PAra o desfecho força, identificou-se que tanto o grupo que treino com restrição do fluxo, quanto o grupo que treinou com alta intensidade tiveram aumentos significativos (p= 0,005 e 0,026, respectivamente). Já em relação ao aumento da circunferência, notou-se que somente o treino de restrição do fluxo se mostrou estatisticamente quando comparado o aumento entre os grupos (p= 0,001). Conclusão: Foi possível concluir que o treinamento com restrição do fluxo sanguíneo mostrou eficaz tanto para o ganho de força, quanto para o aumento de circunferência, apresentando vantagens quando comparado ao grupo de treinamento resistido com alta intensidade.

Published: March 2021

We consider an optimal control problem for the Navier–Stokes system with Navier slip boundary conditions. We denote by α the friction coefficient and we analyze the asymptotic behavior of such a problem as [Formula: see text]. More precisely, we prove that if we take an optimal control for each α, then there exists a sequence of optimal controls converging to an optimal control of the same optimal control problem for the Navier–Stokes system with the Dirichlet boundary condition. We also show the convergence of the corresponding direct and adjoint states.

BACKGROUND: Protein kinase R (PKR) can suppress various types of solid tumors by inducing cellular oxidative stress and apoptosis. Likewise, Slaidorside, a plant flavonoid, was shown to have anti-tumorigenesis in many solid tumors. OBJECTIVE: This study evaluated anti-tumorigenesis of Salidroside in HT29 colorectal cancer and investigated if the underlying mechanism involves activation of PKR. METHODS: Control or PKR deficient cells were cultured in DMEM media treated with 100 μM Salidroside and cell survival, apoptosis, and other biochemical-related markers were evaluated. RESULTS: Salidroside significantly reduced cell survival and proliferation and increased the release of lactate dehydrogenase (LDH) and levels of single-stranded DNA (ssDNA). It also increased the protein levels of caspases 3 and 8. Concomitantly, Salidroside increased the protein level and activity of PKR and increased the expression of its downstream targets, p-eIF2α (Ser51), p53 MAPK, and p53. On the contrary, it inhibited the nuclear activation of STAT-3 and NF-κB p65. In PKR deficient cells, the partial effects of Salidroside on cell survival, proliferation, and apoptotic markers were observed coincided with no effects on the expression of eIF-2α, and JNK, p53, p38 MAPK, and caspase 8 but with a significant decrease in the nuclear activities of STAT3 and NF-κB. CONCLUSION: Salidroside suppresses the tumorigenesis of HT29 CRC by increasing activation of eIF-2α and JNK and upregulation of p53, p38 MAPK, and caspase-8 through upregulating and activation of PKR. However, the tumor suppressor effect of Salidroside requires also inhibition of STAT3 and NF-κB in a PKR-independent mechanism.
Extraction of multimodal features from depth and RGB images for recognising hand gestures
Authors: Suni S.S. , Gopakumar K.
Published: March 2021

In this study, we propose a multimodal feature based framework for recognising hand gestures from RGB and depth images. In addition to the features from the RGB image, the depth image features are explored into constructing the discriminative feature labels of various gestures. Depth maps having powerful source of information, increases the performance level of various computer vision problems. A newly refined Gradient-Local Binary Pattern (G-LBP) is applied to extract the features from depth images and histogram of gradients (HOG) features are extracted from RGB images. The components from both RGB and depth channels, are concatenated to form a multimodal feature vector. In the final process, classification is performed using K-Nearest Neighbour and multi-class Support Vector Machines. The designed system is invariant to scale, rotation and illumination. The newly developed feature combination method is helpful to achieve superior recognition rates for future innovations.
Intra-rater reliability and repeatability of pulse oximetry values obtained before, between sets, and after resistive exercise
Authors: Caruso John F. , Shefflette Alex C.S.
Published: March 2021

BACKGROUND:

Pulse oximetry measures heart rate (HR) and percent oxygen saturation (SpO[Formula: see text]). For aerobic exercise, whereby cellular oxygen demand and delivery are elevated and maintained for extended periods, HR and SpO[Formula: see text] values are consistent when measured by pulse oximetry. Yet due to its intermittent nature, HR and SpO[Formula: see text] values from resistive exercise may exhibit lower data reliability and repeatability.

OBJECTIVE:

Assess intra-rater reliability and repeatability of pulse oximetry HR and SpO[Formula: see text] values from two identical resistive exercise protocols.

METHODS:

Subjects ([Formula: see text] 32) performed two calf press workouts on a flywheel-based ergometer as HR and SpO[Formula: see text] were measured before, between sets, and after exercise. Workouts entailed a 4-set 15-repetition protocol separated by 120-second rests. Intra-rater reliability was assessed with intraclass correlation coefficients (ICC). Repeatability was measured by the smallest real difference in absolute and relative terms.

RESULTS:

ICC and standard error of estimate results for HR ranged from 0.60–0.79 and 9.1–13.0 respectively. SpO[Formula: see text] ICC and standard error of estimate results ranged from 0.16–0.71 and 1.44–4.33 respectively. Between sets, smallest real difference values tended to be less for HR.

CONCLUSIONS:

Results demonstrate acceptable intra-rater reliability and repeatability for HR, but not SpO[Formula: see text] which we attribute to the exercise mode and protocol examined.
Incorporating agile practices in public sector IT management: A nudge toward adaptive governance
Authors: Ylinen Maija
Published: March 2021

Public sector organizations are moving from digitalization toward digital transformation. However, this fast-paced and fundamental transformation can be difficult to manage with traditional approaches. One solution is the application of agile methods and adaptive governance. Currently, it is not clear whether the agile mindset can be successfully adopted by public sector organizations, which value stability over agility. To provide a much-needed example of how the agile approach can be introduced in the context of the public sector, this paper presents the findings of a single case study of a municipal IT department. The case shows how the IT department adopted an agile IT management approach in response to the growing demand for digital services and the effects of the digital transformation inside the IT department and throughout the municipality. The findings reveal that introducing agile IT management in public sector IT departments can help improve operational flexibility, collaboration, and customer service despite barriers, such as traditional operational structures, and resistance to change. Consequently, bottom-up agile experiments can drive large-scale agile transformations, especially if such transformations are also accepted at the organizational level.

Background: Neuropsychiatric symptoms (NPS) are non-cognitive manifestations common to dementia and other medical conditions, with important consequences for the patient, caregivers, and society. Studies investigating NPS in individuals with Down syndrome (DS) and dementia are scarce. Objective: Characterize NPS and caregiver distress among adults with DS using the Neuropsychiatric Inventory (NPI). Methods: We evaluated 92 individuals with DS (≥30 years of age), divided by clinical diagnosis: stable cognition, prodromal dementia, and AD. Diagnosis was determined by a psychiatrist using the Cambridge Examination for Mental Disorders of Older People with Down’s Syndrome and Others with Intellectual Disabilities (CAMDEX-DS). NPS and caregiver distress were evaluated by an independent psychiatrist using the NPI, and participants underwent a neuropsychological assessment with Cambridge Cognitive Examination (CAMCOG-DS). Results: Symptom severity differed between-groups for delusion, agitation, apathy, aberrant motor behavior, nighttime behavior disturbance, and total NPI scores, with NPS total score being found to be a predictor of AD in comparison to stable cognition (OR for one-point increase in the NPI = 1.342, p = 0.012). Agitation, apathy, nighttime behavior disturbances, and total NPI were associated with CAMCOG-DS, and 62% of caregivers of individuals with AD reported severe distress related to NPS. Caregiver distress was most impacted by symptoms of apathy followed by nighttime behavior, appetite/eating abnormalities, anxiety, irritability, disinhibition, and depression (R2 = 0.627, F(15,76) = 8.510, p < 0.001). Conclusion: NPS are frequent and severe in individuals with DS and AD, contributing to caregiver distress. NPS in DS must be considered of critical relevance demanding management and treatment. Further studies are warranted to understand the biological underpinnings of such symptoms.

Background: Patients with dementia are vulnerable during the coronavirus disease 2019 (COVID-19) pandemic, yet few studies describe their hospital course and outcomes. Objective: To describe and compare the hospital course for COVID-19 patients with dementia to an aging cohort without dementia in a large New York City academic medical center. Methods: This was a single-center retrospective cohort study describing all consecutive patients age 65 or older with confirmed COVID-19 who presented to the emergency department or were hospitalized at New York-Presbyterian/Columbia University Irving Medical Center between March 6 and April 7, 2020. Results: A total of 531 patients were evaluated, including 116 (21.8%) with previously diagnosed dementia, and 415 without dementia. Patients with dementia had higher mortality (50.0%versus 35.4%, p = 0.006); despite similar comorbidities and complications, multivariate analysis indicated the association was dependent on age, sex, comorbidities, and code status. Patients with dementia more often presented with delirium (36.2%versus 11.6%, p < 0.001) but less often presented with multiple other COVID-19 symptoms, and these findings remained after adjusting for age and sex. Conclusion: Hospitalized COVID-19 patients with dementia had higher mortality, but dementia was not an independent risk factor for death. These patients were approximately 3 times more likely to present with delirium but less often manifested or communicated other common COVID-19 symptoms. For this high-risk population in a worsening pandemic, understanding the unique manifestations and course in dementia and aging populations may help guide earlier diagnosis and optimize medical management.

Primary segmental intestinal volvulus is a rare condition that may affect neonates. This condition occurs when a loop of bowel torses around the axis of its mesentery without any other abnormality or malrotation. In the earlier stages, the diagnosis can be challenging due to the lack of specific clinical and radiographic signs. Prompt surgical management is critical as a delay in diagnosis may result in bowel loss or death. We present a series of three cases of extremely low birth weight infants with primary segmental volvulus. A sentinel bowel loop was critical in guiding each patient’s surgical management as there were no other clinical markers concerning a pending intra-abdominal catastrophe. This case series suggests that a sentinel bowel loop may be a radiographic marker for primary segmental intestinal volvulus in extremely low birth weight infants.
Improving relevance: Istat experience on experimental statistics
Authors: Carciotto Arianna , Signore Marina
Published: March 2021

In line with Eurostat and other National Statistical Institutes, Istat has been publishing experimental statistics since April 2018. Experimental statistics inform users on topics not fully exploited by official statistics, and differ from them because they are not yet entirely developed. This enlargement of Istat statistical supply was fostered by the satisfaction of users’ needs and the increased availability of new data sources. An internal procedure was set up to select, evaluate and disseminate experimental statistics before their publication on a dedicated area of the Istat website. At Istat, the primary purpose of experimental statistics is to improve relevance. Indeed, they are new statistics or improved existing outputs, which have a value added for the users in terms of “new” or “additional” information available. Important features of experimental statistics are the use of non-traditional data sources, the use of innovative methodologies, the geo-spatial reference or other types of data visualisation, the integration of multiple sources. Up to now, improving timeliness seems to be a less important motivational factor for developing experimental statistics. Recently, the transition from experimental to official statistics was tackled, leading to the definition of a set of criteria to be satisfied.
Implications of the SARS-CoV-2 spike protein interaction with type-1 macrophages via α7-nAChR.

The human immune system has a generic response strategy to viral infections that begins with local inflammation at the infected site along with the initiation of a primary innate immune response. Beyond a certain threshold, innate immune cells cannot handle the infection, and they call upon adaptive immunity. The innate cells then take up their role in “The Resolution of Inflammation”. The recognition of the SARS-CoV-2 antigen triggers an eicosanoid storm and initiates a robust inflammatory response, leading to a sustained cytokine storm that interferes with the activation of adaptive immune cells, specifically BCL6+ B cells. The mechanism of this interaction, and hence the pathogenesis of the virus with the immune system, is yet to be determined. In silico studies predict a direct viral interaction with type 1 resident macrophages, which could initiate the cascade of events described above. The macrophage population being the target would also explain why older age groups are relatively more susceptible to the virus. Here, we review the interaction of the SARS-CoV-2 spike protein via a cryptic epitope with the α7-nAChR in Type-1 macrophages, discuss the implications it might have on our approach to the generic treatment of COVID-19 patients, and present better prospects for the design and dissemination of more effective vaccines and their importance.
