The Sugar-Zombie, Race and Cash-Crop Monocultures
Authors: Oloff Kerstin
Published: January 2024

Chapter two turns to the 1930s, which saw a proliferation of zombies and zombie effects across a number of different locations and genres. Viewing the crisis of the 1930s, heralded by the Wall Street Crash, from the perspective of today is instructive, since today’s economic and environmental crisis has its roots in the former. Reading comparatively, I examine the sugar-zombie alongside zombie-esque figures that map the exhaustion of former commodity frontiers. Gendering, racialisation and proletarianisation are environment-making processes, unfolding through the web of life. The zombie, as a highly racialised and gendered figure, makes manifest these entanglements and helps us to shed light on what one might term the 'ecological unconscious' of modernity.
Holiday Horror
Authors: Wiggins Steve A.
Published: January 2024

Holiday horror is a sub-genre in which the horror of a film is drawn from a holiday. This generally takes place because holidays are religious in origin and therefore are only vaguely understood. The Wicker Man is holiday horror based on May Day.
May Day
Authors: Wiggins Steve A.
Published: January 2024

The Wicker Man is set on May Day and draws its energy from it. May Day, or Beltane, is an ancient Celtic festival whose origins and practice are mostly lost to history. To understand the movie it is necessary to consider the reconstructed May Day it uses.
Manhunter and Modernism
Authors: Swan Deryck
Published: January 2024

Chapter 6 begins by establishing the pre-eminence of Mann’s 4th work and its achievement as arguably the first film to introduce terminology like serial killer and forensic profiling. It then lays out Manhunter’s conceptual debts to Fritz Lang’s M and Alfred Hitchcock’s Psycho, both in terms of those films’ presentations of the dual personality and their frank treatment of cinematic violence. It details the complex mise en scene of the Manhunter and the way in which it mirrors the mania of the central characters, something the book terms its psychogeography.
Heat and Los Angeles
Authors: Swan Deryck
Published: January 2024

Chapter 8 explores the lodestone of Mann’s filmography and its enduring popularity via an ethnographic assessment of the film’s host city, Los Angeles. It signposts Heat’s thorough reconfiguration of the city - from its prior incarnations as a tropical hellhole or locus for period nostalgia - into something indelibly modern and futuristic, thereby setting an enduring template that would reappear in films like Drive and Nightcrawler. It aligns the city with the film’s narrative concerns and details the multi-faceted connections between the two.
A Phenomenon Resembling Early Superhumps in a New SU UMa-type Dwarf Nova with a 2 hr Orbital Period
Authors: Boyle Rebecca S. , Littlefield Colin , Garnavich Peter , Ridden-Harper Ryan , Szkody Paula , Boyd Patricia , Smith Krista Lynne
Published: January 2024

We investigate K2BS5, an optical transient that we identified in Campaign 13 of the Kepler/K2 archives by the K2 Background Survey, and classify it as a new SU UMa-type dwarf nova. Using the light curve generated from Keplers long-cadence observation mode, we analyze the dwarf nova during quiescence and superoutburst. Following 20 days of quiescence at the start of the observation, the system entered a superoutburst lasting 12 days, after which it experienced at least one rebrightening. K2BS5 clearly meets the criteria for an SU UMa star, but at the peak of the superoutburst, it also shows double-wave oscillations consistent with the spectroscopic orbital period, a phenomenon that closely resembles early superhumps in WZ Sge stars. While we do not classify K2BS5 as a WZ Sge system, we discuss how this phenomenon could complicate efforts to use the suspected detection of early superhumps to distinguish SU UMa-type dwarf novae from the recently recognized class of long-orbital-period WZ Sge systems.
ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): Molecular Jets and Episodic Accretion in Protostars

Protostellar outflows and jets are almost ubiquitous characteristics during the mass accretion phase and encode the history of stellar accretion, complex organic molecule (COM) formation, and planet formation. Episodic jets are likely connected to episodic accretion through the disk. Despite the importance, studies on episodic accretion and ejection links have not been done yet in a systematic fashion using high-sensitivity and high-resolution observations. To explore episodic accretion mechanisms and the chronologies of episodic events, we investigated 39 fields containing protostars with Atacama Large Millimeter/submillimeter Array observations of CO, SiO, and 1.3 mm continuum emission. We detected SiO emission in 19 fields, where 17 sources are driving molecular jets. Jet velocities, mass-loss rates, mass accretion rates, and periods of accretion events appear to have some dependence on the driving forces of the jet (e.g., bolometric luminosity, envelope mass). Next, velocities and mass-loss rates appear to be somewhat correlated with the surrounding envelope mass, suggesting that the presence of high mass around protostars increases the ejection–accretion activity. We determine mean periods of ejection events of 20–175 yr for our sample, which could be associated with perturbation zones of ∼2−25 au extent around the protostars. In addition, mean ejection periods show an apparent anticorrelation with the envelope mass, where high accretion rates may trigger more frequent ejection events. The observed periods of outburst/ejection are much shorter than the freezeout timescale of the simplest COMs like CH3OH, suggesting that episodic events could affect the ice–gas balance inside and around the snowline.

Ongoing observing projects like the James Webb Space Telescope and future missions offer the chance to characterize Earth-like exoplanetary atmospheres. Thereby, M dwarfs are preferred targets for transit observations, for example, due to their favorable planet–star contrast ratio. However, the radiation and particle environment of these cool stars could be far more extreme than what we know from the Sun. Thus, knowing the stellar radiation and particle environment and its possible influence on detectable biosignatures—in particular, signs of life like ozone and methane—is crucial to understanding upcoming transit spectra. In this study, with the help of our unique model suite INCREASE, we investigate the impact of a strong stellar energetic particle event on the atmospheric ionization, neutral and ion chemistry, and atmospheric biosignatures of TRAPPIST-1e. Therefore, transit spectra for six scenarios are simulated. We find that a Carrington-like event drastically increases atmospheric ionization and induces substantial changes in ion chemistry and spectral transmission features: all scenarios show high event-induced amounts of nitrogen dioxide (i.e., at 6.2 μm), a reduction of the atmospheric transit depth in all water bands (i.e., at 5.5–7.0 μm), a decrease of the methane bands (i.e., at 3.0–3.5 μm), and depletion of ozone (i.e., at ∼9.6 μm). Therefore, it is essential to include high-energy particle effects to correctly assign biosignature signals from, e.g., ozone and methane. We further show that the nitric acid feature at 11.0–12.0 μm, discussed as a proxy for stellar particle contamination, is absent in wet-dead atmospheres.
Constraining Neutrino Cosmologies with Nonlinear Reconstruction
Authors: Zang 臧 Shi-Hui 诗慧 , Zhu 朱 Hong-Ming 弘明
Published: January 2024

Nonlinear gravitational evolution induces strong nonlinearities in the observed cosmological density fields, leading to positive off-diagonal correlations in the power spectrum covariance. This has caused the information saturation in the power spectrum, e.g., the neutrino mass constraints from the nonlinear power spectra are lower than their linear counterparts by a factor of ∼2 at z = 0. In this paper, we explore how nonlinear reconstruction methods improve the cosmological information from nonlinear cosmic fields. By applying nonlinear reconstruction to cold dark matter fields from the Quijote simulations, we find that nonlinear reconstruction can improve the constraints on cosmological parameters significantly, nearly reaching the linear theory limit. For neutrino mass, the result is only 12% lower than the linear power spectrum, i.e., the theoretical best result. This makes nonlinear reconstruction an efficient and useful method to extract neutrino information from current and upcoming galaxy surveys.
Enhanced Magnetic Field Amplification by Ion-beam Weibel Instability in Weakly Magnetized Astrophysical Shocks
Authors: Jikei Taiki , Amano Takanobu , Matsumoto Yosuke
Published: January 2024

We examine the evolution of ion-beam Weibel instability at strong collisionless shocks in weakly magnetized media. We find that a finite background magnetic field substantially affects both the linear and nonlinear phases of the instability, depending on whether the background electrons behave magnetized or not. Particle-in-cell simulations for magnetized electrons identify a dynamo-like mechanism of magnetic field amplification, which eventually leads to spontaneous magnetic reconnection. We conclude that this scenario is applicable to typical young supernova remnant shocks.

Published: January 2024

The adult, pupa and larva of a new species, Gnaptorina (Gnaptorina) lhorongica Li, sp. nov., from northeastern Xizang, China are described and illustrated. The species was identified using molecular phylogenetic analyses based on three mitochondrial fragments and one nuclear gene fragment (COI, Cytb, 16S, and 28S-D2). The taxonomic status of the new species is confirmed using a combination of molecular and morphological datasets. This study provides valuable molecular and morphological data for phylogenetic studies of the tribe Blaptini.
Exit Polls and Voter Turnout in the 2017 French Elections
Authors: Grillo Alberto , Raiber Eva
Published: January 2024

Lors des élections françaises, les médias belges et suisses interfèrent régulièrement en publiant des sondages et des prédictions avant la fermeture des bureaux de vote. Nous utilisons la précocité et le degré de confiance inhabituels des sondages au second tour de l’élection présidentielle de 2017 pour étudier leurs effets sur la participation électorale. Notre analyse compare les taux de participation à différents horaires, aux premier et second tours, et par rapport aux élections de 2012 et 2022. Les résultats montrent une baisse significative de la participation après la publication des sondages à la sortie des urnes. L’effet s’élève à 1,1 point de pourcentage dans l’analyse en triples differences avec l’élection de 2022 et il est plus fort dans les départements limitrophes de la Belgique. Nous constatons également un léger effet underdog pouvant réduire la marge de victoire jusqu’à 1 point de pourcentage.
Existence and concentration of homoclinic orbits for first order Hamiltonian systems
Authors: Wang Tianfang , Zhang Wen
Published: January 2024

This paper is concerned with the following first-order Hamiltonian system

   \begin{document}$ \begin{equation} \nonumber \dot{z} = \mathscr{J}H_{z}(t, z), \end{equation} $\end{document}

where the Hamiltonian function $ H(t, z) = \frac{1}{2}Lz\cdot z+A(\epsilon t)G(|z|) $ and $ \epsilon > 0 $ is a small parameter. Under some natural conditions, we obtain a new existence result for ground state homoclinic orbits by applying variational methods. Moreover, the concentration behavior and exponential decay of these ground state homoclinic orbits are also investigated.
Stability analysis of switching systems with all modes unstable based on a $ \Phi $-dependent max-minimum dwell time method
Authors: Yu Qiang , Feng Yuanyang
Published: January 2024

This paper applies stable and unstable switching instants to study switching systems with unstable modes under time-dependent switching signals. A new Lyapunov function is proposed to study the properties of switching instant using different $ \Phi $-dependent max-minimum dwell time methods. After that, the global exponential stability conditions for nonlinear and linear switching systems are derived and stable switching is used to compensate for unstable switching and unstable modes. The relevant results are extended to the controller design of linear switching systems. Finally, a simulation verifies the effectiveness of the results of this paper.
Moment inequalities for multinomial choice with fixed effects
Authors: Pakes Ariel , Porter Jack
Published: January 2024

This paper proposes a new approach to identification of the semiparametric multinomial choice model with fixed effects. The framework employed is the semiparametric version of the traditional multinomial logit with the fixed‐effects model (Chamberlain (1980)). This semiparametric multinomial choice model places no restrictions on either the joint distribution of the random utility disturbances across choices or their within group (or across time) correlations. We show that a novel within‐group comparison leads to a set of conditional moment inequalities. Our main finding shows that the derived conditional moment inequalities yield the sharp identified set for the random utility covariate index, while avoiding the incidental parameter problem. Specializing this result to the binary choice case shows that Manski (1987)'s conditional moment inequalities still lead to sharp bounds without restrictions on covariates.
A robust permutation test for subvector inference in linear regressions
Authors: D'Haultfœuille Xavier , Tuvaandorj Purevdorj
Published: January 2024

We develop a new permutation test for inference on a subvector of coefficients in linear models. The test is exact when the regressors and the error terms are independent. Then we show that the test is asymptotically of correct level, consistent, and has power against local alternatives when the independence condition is relaxed, under two main conditions. The first is a slight reinforcement of the usual absence of correlation between the regressors and the error term. The second is that the number of strata, defined by values of the regressors not involved in the subvector test, is small compared to the sample size. The latter implies that the vector of nuisance regressors is discrete. Simulations and empirical illustrations suggest that the test has good power in practice if, indeed, the number of strata is small compared to the sample size.
A dynamic model of censorship
Authors: Sun Yiman
Published: January 2024

We study the interaction between an agent of uncertain type, whose project gives rise to both good and bad news, and an evaluator who must decide if and when to fire the agent. The agent can hide bad news from the evaluator at some cost, and will do so if this secures her a significant increase in tenure. When bad news is conclusive, censorship hurts the evaluator, the good agent, and possibly the bad agent. However, when bad news is inconclusive, censorship may benefit all those players. This is because the good agent censors bad news more aggressively than the bad agent, which improves the quality of information.
Nuits de Beyrouth
Authors: Bonte Marie
Published: January 2024

Cette géographie des loisirs nocturnes à Beyrouth nous emmène au-delà du cliché des nuits enflammées et sans fin de la capitale libanaise, pour analyser les espaces de sociabilités festives, les pratiques des acteurs qui produisent et fréquentent cet univers au quotidien, et les représentations qui lui sont associées. Dans cet ouvrage, Marie Bonte croise les problématiques liées aux usages ludiques de la nuit avec les questions que posent les héritages complexes des conflits, notamment de la guerre civile libanaise. Ce faisant, elle montre comment les pratiques liées à l’alcool, la drague, la danse, constituent des manières de produire et de se réapproprier l’espace urbain, mais aussi d’énoncer un possible vivre-ensemble au-delà des assignations identitaires que le conflit a imposées et matérialisées dans la ville. Au cœur des problématiques de la géographie sociale, culturelle et politique, et intégrant des éléments de marketing territorial, l’ouvrage revisite les questions urbaines au Proche-Orient et de gestion du post-conflit.
Entre expressivité et persuasivité : penser le play design des apprentissages et des discours à partir The Witness
Authors: Giner Esteban
Published: January 2024

The Witness (2016, Thekla Inc.) est un jeu d’exploration et de résolution d’énigmes si le joueur ou la joueuse le décide. Son parti pris, fort dans la façon qu’il a de proposer des éléments de discours, lui confère un éthos à cheval entre persuasive games et expressive games. Or, ces deux genres ne semblent identifiables que par les intentions de leurs auteurs. Dans cet article, nous proposons un modèle permettant d’observer plus finement l’expressivité et la persuasivité des jeux vidéo. Pour cela, nous partons de la pédagogie pour identifier les jeux comme des contextes proposant des situations communicationnelles qui peuvent aboutir à des apprentissages potentiels. L’identification des approches communicationnelles permet alors de statuer sur la persuasivité ou l’expressivité d’un discours contenu dans un jeu à propos d’un objectif précis. Ainsi, plutôt que d’analyser directement un message contenu dans un jeu, nous proposons une méthode analysant les stratégies discursives que nous associons au play design d’un jeu. The Witness sert ici d’étude de cas. En appliquant la méthode que nous proposons, nous statuons sur les divers objectifs de son play design.
Qu’est-ce que l’exploration vidéoludique ?
Authors: Grandjean Guillaume
Published: January 2024

La notion d’exploration est aujourd’hui centrale dans le discours vidéoludique : rares sont les jeux qui ne proposent pas d’explorer quelque chose, quand d’autres se réclament même d’un nouveau genre que serait le « jeu d’exploration ». Sous cette appellation se rencontrent pourtant des jeux aux caractéristiques très diverses, dont l’apparition ne date pas des walking simulators, mais remonte aux tout premiers jeux d’aventure textuels. Cependant, aucune tentative de définition du terme n’a jusqu’ici été proposée par la recherche en études vidéoludiques. Après un bref historique de son association au jeu vidéo, la présente contribution tente de procéder à un éclairage conceptuel de la notion d’exploration à partir des apports de l’épistémologie historique (Gallegos Gabilondo, 2018), en dégageant certaines valeurs liées à l’activité exploratoire en relation avec le type d’espaces dans lesquels elle s’exerce. Deux valeurs primaires sont ainsi mises en avant, rattachant l’exploration vidéoludique à son équivalent historique : l’exploration « plinienne » d’une part, c’est-à-dire l’exploration comme productrice de récits, et l’exploration « ptoléméenne » d’autre part, c’est-à-dire l’exploration comme productrice de savoirs. À ces deux aspects traditionnels de l’activité exploratoire, nous proposons d’ajouter une troisième valeur, plus spécifique au jeu vidéo, la valeur esthétique de l’exploration, abordée par le biais de l’analyse phénoménologique. L’exploration est ainsi présentée comme l’activité synthétique par excellence d’une certaine vision du jeu vidéo, conçu comme système encyclopédique, narratif et esthétique.
Appréhender l’histoire de l’industrie vidéoludique française par l’étude de ses réseaux de distribution : enjeux et apports
Authors: Sidre Colin
Published: January 2024

De l’arrivée des premières consoles de jeux vidéo en France au milieu des années 1970, à la concentration de l’industrie autour de plusieurs consoliers au milieu des années 1990, l’industrie vidéoludique française connait des évolutions singulières. Les comprendre nécessite de s’intéresser à une figure peu étudiée de l’industrie : celle du distributeur et du revendeur de jeu vidéo. Décentrer le regard en direction de cette figure met en évidence plusieurs traits caractéristiques de l’industrie française : ainsi de la séparation progressive des fonctions d’éditeur et de distributeur, ou de la diversité des formes matérielles prises par le jeu vidéo sur une vingtaine d’années.

Socio-Economic Determinants of Terrorism in Tunisia
Authors: Dardouri Nesrine , Aguir Abdelkader , Smida Mounir
Published: January 2024

Tunisia has always been affected by terrorism, but since the late 2011s there has been a sharp increase in terrorism perpetrated. The object of this research is to analyze the socio-economic determinants of terrorism using terrorist attacks as a dependent variable and indicators that affect the level of growth in Tunisia such as explanatory variables. The aim of this work is to develop recommendations on how to respond to the state in response to terrorist shocks. The following policy implications were deduced. First, we must increase the level of growth of the country by stabilizing the policy and by controlling governance to show the effectiveness of the results of this study which aims at reducing terrorism and improving the country's economic conditions. Second, in view of the results found in this research, terrorism can stabilize the long-term labor market through investment by putting in place realistic economic policies that are time-bound to encourage the State to create vacancies for the unemployed.
A Tripartite Evolutionary Game Model for Chinese-Style Education Investment in ASEAN Under Local Government Policy
Authors: Zhu Zheqi , Zhai Kun
Published: January 2024

With the deepening of the Belt and Road Initiative (BRI), many Chinese have been dispatched to Southeast Asian countries to participate in technical support and management. However, there are no OCE schools locally that can provide educational resources for their children. The decision of whether to invest in overseas Chinese-OCE has become a challenge for Chinese education groups. In this paper, the authors put forward an evolutionary game analysis scheme to study the OCE investment decisions among host country governments, students, and Chinese enterprises. The simulation results show that (1) the government's subsidy is always helpful to Chinese enterprise, especially at the beginning stage, (2) applying a soft strength of positive execution and combining with other methods could encourage the enterprise at the beginning and regulate the market later on, and (3) high strength of high support of government for the educational infrastructure is a win-win method for both students and the enterprise. Some managerial insights and suggestions are proposed based on these results.
Application of Behavior Recognition Technology Based on Deep Learning in Elderly Care
Authors: Zhang Shihui , Mi Jing , Liu Naidi
Published: January 2024

China is currently one of the countries with the largest elderly population in the world, and the issue of population aging has become a widespread concern. The behavior recognition algorithm based on deep learning is currently the main behavior recognition algorithm and one of the basic technologies in the field of computer vision. In existing research, the method of constructing complex classification models based on manual feature representation can no longer meet the requirements of high recognition accuracy and applicability, and the introduction of deep learning has brought new development directions for behavior recognition. Therefore, this article aims to study how to apply deep learning-based behavior recognition technology more accurately and effectively in the care of elderly people in the context of “artificial intelligence.”
Análise de dados Harmonized Landsat Sentinel para mapeamento de uso e cobertura da terra em área de expansão agrícola no Cerrado

Published: January 2024

Diferentes iniciativas de mapeamento de uso e da cobertura da terra por sensoriamento remoto orbital têm sido realizadas com objetivo de apoiar o planejamento agroambiental no Cerrado. No entanto, a complexa dinâmica agropecuária regional exige um maior detalhamento na discriminação dos usos agrícolas, tarefa que exige séries temporais de imagens de satélite. Este estudo objetivou avaliar se o uso integrado de dados Landsat 8 Operational Land Imager (OLI) e Sentinel-2 Multispectral Instrument (MSI) pode contribuir para o possível aumento da exatidão de classificações digitais de uso e cobertura da terra em região de expansão agrícola no Cerrado. Para isso, o município de Balsas, que possui relevante interesse econômico e agroambiental, foi escolhido como área de estudo para avaliar a performance de modelos Random Forest de classificação gerados com dados dos sensores OLI/Landsat 8 e MSI/Sentinel 2, de forma individual e integrada, por meio de uma base de dados inovadora Harmonzed Landsat Sentinel 2 (HLS).  Os modelos MSI, HLS e OLI apresentaram performance semelhante, com Exatidão Global de 0,857, 0,844 e 0,832, e índice de Kappa de 0,819, 0,803 e 0,787, respectivamente. O Teste T indicou que esses resultados não são estatisticamente diferentes entre si.  Apesar da performance do modelo, o mapa final elaborado com os dados OLI apresentou elevadas perdas de informações por ausência de pixels na série temporal. Os novos dados HLS mostraram-se aptos para mapeamento de uso e cobertura, mesmo em larga escala, em resolução de 30 m, com muito boa exatidão e tempo reduzido de processamento em relação aos dados MSI. Os resultados obtidos podem apoiar a tomada de decisão no planejamento e execução de novos mapeamentos agrícolas do Cerrado.
Reconhecendo a área de influência do IFNMG Teófilo Otoni: uma proposta metodológica a partir do local de residência dos discentes do Ensino Médio Integrado
Authors: Morais Sérgio Lana , Diniz Alexandre Magno Alves
Published: January 2024

Os Institutos Federais de Educação, Ciência e Tecnologia (IF’s) foram ampliados nas primeiras décadas do século XXI e culminaram em um processo de interiorização que ainda carece de um mapeamento mais sistemático quanto à abrangência dos seus campi. Foi a partir desse pressuposto que a pesquisa buscou identificar o alcance espacial do Instituto Federal do Norte de Minas Gerais (IFNMG) Campus Teófilo Otoni – com base no local de moradia dos seus discentes – vis-à-vis a sua área de abrangência institucionalmente verificada e analisar a possível sobreposição com outras unidades do IFNMG, especialmente Almenara, Araçuaí e Diamantina. Os recursos metodológicos utilizados se associaram à revisão de literatura, à obtenção de dados primários dos discentes matriculados nos cursos técnicos integrados entre os anos letivos de 2016 a 2022 com a Coordenação de Registros Escolares e Acadêmicos e a espacialização dos dados em um Sistema de Informação Geográfica. Para o período analisado, a baixa diversidade de municípios com discentes que realizam o movimento pendular em direção ao IFNMG pode ser explicada pelos deslocamentos com até 60 minutos de duração pelo transporte público e em um raio inferior a 45 quilômetros. Os demais municípios estão geograficamente distantes e com um tempo de deslocamento que inviabiliza o movimento pendular. Por isso, a espacialização que emprega a Região Imediata de Teófilo Otoni como referência espacial parece ser a mais adequada para delimitar a sua real área de influência.

PROCESSOS DE SOCIALIZAÇÃO NA FORMAÇÃO DE PORTFÓLIOS FINANCEIROS DE INVESTIDORES DE VAREJO
Authors: Verhine Alan , Lodi Marluce
Published: January 2024

Esta pesquisa parte de duas premissas. A primeira é que investidores de varejo estabelecem uma relação de consumo com instituições financeiras ao adquirirem produtos de renda fixa e/ou variável. A segunda premissa é os processos de socialização desses investidores-consumidores influenciam e são construídos nas decisões sobre a aquisição de produtos de investimento. O objetivo deste artigo foi identificar elementos das trajetórias dos sujeitos - utilizando conceitos da sociologia de Bourdieu - e associá-los à aplicação do recurso financeiro. Para alcançar a proposta, foram realizadas entrevistas com investidores individuais e aplicada, posteriormente, a Análise de Conteúdo. As entrevistas, além de revelarem a influência dos pais na gestão do dinheiro, apontaram que os investidores com preferência para a renda variável compartilham experiências no mercado financeiro nas relações interpessoais e se concentram no acúmulo de capital informacional sobre finanças; já os entrevistados com preferência para a renda fixa não possuem interesse na dinâmica do mercado e se apoiam em questões extraeconômicas na escolha dos produtos financeiros.

Published: January 2024

Background:

Childhood fractures are frequent. The aim of this study was to evaluate their epidemiological and clinical peculiarities in our context.

Materials and Methods:

This was a retrospective study that focused on the files of children with a fracture. They were aged 0–15 years and received between January 2011 and December 2015 at the Emergency Department of the National Teaching Hospital of Cotonou.

Results:

Two hundred and eighty fractures were recorded in 257 children. The average age was 8.24 years (7 days–15 years). Older children (6–10 years) were the most affected with 33.8% of cases. The predominance was male (sex ratio = 2.3:1). The aetiologies were dominated by road traffic accidents (45.1%) followed by domestic accidents (42.7%). Fractures were predominant in the lower limbs (52.1%). The most affected segments were the leg (25.4%) and the femur (23.6%). The fracture was open in 13.9% of cases.

Conclusion:

Childhood fractures interest preferentially the older boys. Then, road traffic accidents are the most frequent circumstances of occurrence in our context. Measures to prevent the main causes of these fractures must be taken, in order to reduce their frequency and ensure the development of children.

Objective:

The authors report their experience of the transanal endorectal pull through technique as described by De la Torre Mondragon in the treatment of Hirschsprung’s disease (HD).

Materials and Methods:

It was a retro prospective, observational and descriptive hospital based study involving all proven cases of HD managed within a time frame of 8 years.

Results:

Fifty two patients with a mean age of 18 months at the time of surgery. The male pre dominance was remarkable. The mean duration of the surgery was 2 h and a half hours. The surgical indication was based on the history, clinical findings and on the contrast enema (transition zone) with a 24 h film (prolonged contrast evacuation) and calculation of the rectosigmoid index (<1). With a mean follow up of 16 months, the morbidity was dominated by soiling, anastomotic strictures and enterocolitis. The mortality in one case was related to a post operative enterocolitis that was not amenable to resuscitation.

Conclusion:

Soiling, anastomotic strictures and enterocolitis are the main post operative complications of TEPT in the treatment of HD in our practice.

Penile agenesis is complete absence of the penis in an otherwise normal phenotypic and genotypic male at birth that results from failure of development of the genital tubercle. It is an extremely rare anomaly that may be associated with anomalies in other organ systems, the extent and severity of which may affect the prognosis. The management is challenging and may have far reaching implications for the individual and family. While gender reassignment with bilateral orchidectomy and feminising genitoplasty has been carried out for most patients, significant psychosexual and social issues related to the male identity may occur due to foetal or postnatal sex steroid imprinting. We report a neonate with penile agenesis with bilateral renal agenesis and anorectal malformation.

Published: January 2024

Background:

It is important to study the clinical profile of pediatric patients with acute lymphoblastic leukemia (ALL) and assess various prognostic factors implicated in response to induction chemotherapy for optimal treatment outcomes in India. The present study was done to evaluate the clinical profile and to find the correlation of day 7 and day 28 marrow blast response with already established prognostic factors in children with ALL in the region of North India using MCP 841 protocol for all patients.

Methods:

A total of 60 children up to ages 14 years with ALL were given treatment in the form of induction remission (MCP-841 protocol) I1 cycle (induction 1) therapy for 29 days. Complete hemogram for blast cells and bone marrow examination (bone marrow aspiration and, if required, bone marrow biopsy) was done on days 7 and 28 (completion of I1 cycle) to see early bone marrow response. Early response to induction therapy was compared in patients with and without high-risk factors, and results were analyzed statistically.

Results:

Out of 60 enrolled children, 56 (93.4%) patients were in complete remission at the end of induction 1 cycle. Various risk factors were found to be of prognostic significance in first remission and early response to induction therapy were initial total leukocyte count (TLC) at presentation, immunophenotype of ALL; while other factors including age and sex was not found to be significant.

Conclusion:

Prevalence and significance of various prognostic factors implicated in pediatric ALL tend to be different in various populations. A better understanding of such factors in these populations will help in the tailoring of risk-adapted treatment protocols to local needs.

Background:

In the past two decades, the growing economy associated with changes in lifestyle-related behavior is partially responsible for the increasing cancer burden in India. To assess the occurrence and distribution of oral cancer based on the analysis of hospital records from registered oncology institutes of South India over a period of three years.

Materials and Methods:

A multicenter, retrospective study was conducted at seven major hospitals in South India to assess the incidence and distribution of cancer among patients over a period of three years (2016–2018). Data were collected on a custom-made validated proforma. Analysis was done using R commander software.

Results:

A total of 156090 various types of cancers were reported to the included institutes over a three-year period, an almost similar gender distribution was observed, males (n = 78806, 42.99% per lakh) compared to their female counterparts (n = 77284, 42.16% per lakh). Among males’ lung cancer was the most common type with 17709 cases (9.65% per lakh) and among females, breast cancer was the leading cancer type with 22855 total cases (12.46% per lakh). Over a period of three years, a total of 21084 records of malignancies pertaining to oral cavity were identified accounting for 13.51% of cases. Among oral cancers, tongue was the most common site to be involved accounting for 44.22% (2016–2018) cases followed by buccal mucosa (14.69%), least common site to be involved was lip which accounted for 3.49% of the total oral cancer cases.

Conclusion:

Breast cancer was the most common cancer followed by lung cancer. Oral cancers occupied second among males and fifth rank in the order of occurrence among females. Tongue was the most common site followed by buccal mucosa. The least common site affected by oral cancer was the lip.
Promoting Millets: Charting a Journey from Food Security to Health
Authors: Jain Vishakha , Agarwal Neeraj , Bhatia Vikas
Published: January 2024

Millets have been the staple food in many parts of the world, but in recent times they have been losing ground because of the increased use of processed foods and grains, such as wheat and rice. India has been the granary of millets due to the largest production and export of Indian millets globally. The very nature of millets being drought-resistant, small seeded grass, which can be grown in arid conditions, with less water and less farming intensive, makes it a great choice for ecological agriculture and sustainable source of food for combating hunger in the rapidly changing global climate and constructing climate-resistant agri-food systems. The various health benefits of millets make them an excellent choice for patients with celiac disease, type 2 diabetes mellitus, ischemic heart disease, dyslipidemia, obesity, etc.
Drawing the Linkage Between Women’s Reproductive Health, Climate Change, Natural Disaster, and Climate-driven Migration: Focusing on Low- and Middle-income Countries - A Systematic Overview
Authors: Afzal Fahad , Das Arindam , Chatterjee Soumitra
Published: January 2024

Background:

One of the most important aspects of women’s well-being and welfare is RSH (reproductive and sexual health). Reproductive health is not an exception to the threat that CCC (climate change and climate crisis) poses to numerous facets of public health. Firstly, the present review seeks to identify the influence of climatic changes, natural disasters, and climate-driven migration on RSH. Secondly, to identify knowledge gaps regarding the same.

Material and Methods:

Two databases (Scopus and PubMed) were scanned using Boolean operation. The literature search aimed to find records pertaining to topics of RSH and climate change. Using the PRISMA-ScR method, records were screened and shortlisted based on established inclusion criteria. This literature search was carried out in November 2022. In the shortlisted records, preference for the comprehensive review articles was given.

Results:

The present review is based on 38 records that collectively revealed that climate crisis and natural disasters have many negative impacts on female reproductive health. These effects are observed in different phases of life, ranging from teenage to menopause. The unique strength of the present review is that it draws a relationship between female reproductive health and the direct as well as indirect effects of the CCC. The available literature about LMICs is predominantly confined to drought, flood, and earthquake. Disasters like tsunamis, cyclones, and avalanches remain unexplored.

Conclusion:

From the available literature, it is quite evident that CCC has an adverse effect on a woman’s reproductive life as well as a bearing on future generations’ health. Filling these knowledge gaps is pivotal for designing more effective disaster and health policies. Policymakers should take into consideration these detrimental effects while designing health schemes and policies for females.

Published: January 2024

Background:

Soil-transmitted helminth (STH) infections are widespread in developing countries with inadequate sanitation facilities. These infections can lead to malnutrition, anemia, and other complications that can negatively impact both the mother’s and fetus’s health during pregnancy. This study aimed to estimate the burden of STH by Kato-Katz microscopy and quantitative polymerase chain reaction (qPCR) in pregnant women from rural India. The diagnostic accuracy of these two methods was also compared.

Material and Methods:

A community-based cross-sectional study was conducted in rural areas of Wardha district of Maharashtra state. We randomly selected and interviewed 688 pregnant women. A total of 534 (77.61%) participants gave stool samples. Two containers (60 mL) labeled with a unique identification number were given to pregnant women to collect stool samples for Kato-Katz microscopy and qPCR. Stool specimens were transported to an accredited lab and examined within 24 hours. Suitable examinations were conducted to compare sensitivity between two tests.

Results:

The results are presented for 534 participants who gave stool samples. The prevalence of any STH by Kato-Katz stool microscopy was 6.55% (95%CI 4.46–12.19), and that by qPCR was 20.41 (95%CI 17.53–29.40). The sensitivity of Kato-Katz microscopy was 29.17% compared to sensitivity of 90.83% by qPCR (P = 0.001). Pregnant women with STH infection have a significantly lower weight gain during pregnancy, and the majority were either mild or moderate anemic compared to those without STH.

Conclusion:

The study highlighted significant differences in prevalence of STH among pregnant women by Kato-Katz microscopy and qPCR. The sensitivity of qPCR for detecting STH was higher than that of Kato-Katz microscopy.

Published: January 2024

Background:

Currently, most old age homes in India are completely occupied. Nowadays, nuclear families are more than joint families, and due to various factors such as urbanization, the elderly are deprived of essential care at home and are moved from their own homes to old-age homes. With the increasing geriatric population, this study explored the various social factors influencing the elderly to reside in old age homes.

Material and Methods:

The study was conducted among 330 elderly in old age homes using simple random sampling. The study population included elderly above the age of 60 years and residing in old age homes, who were willing to participate. A pretested structured questionnaire with data on sociodemographic characteristics, family, financial support, and various other social factors was collected. Data were analyzed using SPSS.

Results:

Among the respondents, 20.6% were supported by children financially and 18.5% had a pension. Almost 70% of the elderly were left unattended by friends and family. Care and support through means of calls, letters, and visits when analyzed showed that 27.3% were provided care and support through children and 33.6% were left unattended.

Conclusion:

Family members, friends, and relatives should be encouraged to give regular visits and spend time with the elderly so that the bonding will have a positive effect on their mental health. Aging and geriatric health should be considered sensitively and should be made mandatory for schools and colleges to arrange visits to old age homes, thereby keeping the younger generation aware of the issues.
