Pouvoirs du disque et du tourne-disque au cinéma. Analyse de ces objets dans deux films contemporains
Authors: Dufays Sophie
Published: February 2020

Cet article s’interroge sur les rôles et les significations du tourne-disque et du disque vinyle au cinéma, en procédant de deux manières complémentaires. D’abord, il passe en revue de manière panoramique les principaux pouvoirs de ces objets tels que le cinéma les a exploités, en mentionnant quelques exemples classiques. Ensuite, il se concentre sur deux films (latino-américains) récents, situés dans le présent contemporain au moment du tournage et protagonisés par des jeunes gens, pour lesquels le tourne-disque est un objet du passé. En effet, dans 25 Watts (Stoll et Rebella, 2001, Uruguay) et Abrir puertas y ventanas (Mumenthaler, 2011, Argentine), le tourne-disque est mis en scène comme un objet désuet, provenant d’une génération antérieure, que les jeunes personnages s’approprient au sein d’un processus d’apprentissage et/ou de deuil. L’article analyse les différentes versions de ce processus dans les films et montre que le tourne-disque apparait comme un marqueur signifiant de celui-ci. Il n’intervient que dans une seule scène des films, mais son utilisation rend compte de la structure temporelle de la narration et du rapport des personnages à leur époque.
D’une nostalgie à l’autre : La trilogie romanesque Wayward Pines, entre rétro fordiste et restauration d’un passé préindustriel
Authors: Duret Christophe
Published: February 2020

Cet article porte sur la trilogie romanesque Wayward Pines, de Blake Crouch. Dans le cadre de cette fiction post-catastrophique, une ville conçue sur le modèle d’une banlieue idéale de l’après-guerre américain est reconstruite et tient lieu d’arche à une humanité au bord de l’extinction. L’objet rétro, qui y tient une grande place, est abordé ici en tant qu’embrayeur d’un milieu et d’un mode d’habiter fordiste, suburbain et écologiquement insoutenable dont il est fait l’analyse. Le texte, dans son appréciation du milieu et de l’habiter en question, témoigne d’une attitude rétro qui balance entre nostalgie restauratrice et distance réflexive, alors qu’un habiter alternatif est proposé, porteur d’une volonté de reconduire dans le futur une ère préindustrielle, néo-agraire et écologiquement soutenable. L’article propose une lecture mésocritique des nostalgies rétro et préindustrielle mises en coprésence dans l’univers fictionnel des romans.
Les dynamiques d’hybridité au sein d’un projet multipartenaire
Authors: Larroche Valérie , Dymytrova Valentyna
Published: February 2020

Dans une approche constitutive de la communication, les auteurs étudient l’hybridité à partir de leur participation à un projet de recherche multipartenaire, qui vise la conception d’une boite à outils facilitant la ré-utilisation des données ouvertes. L’hybridité renvoie ici à une articulation entre plusieurs logiques, objectifs, croyances et valeurs de différents acteurs du projet. Elle se construit dans la durée du projet au travers de négociations, de pratiques et d’ajustements de points de vue autour des objets intermédiaires qui sont ici principalement des objets techniques en cours de conception, des textes accompagnant le déroulement du projet et deux expérimentations. L’agentivité des textes, celle des objets techniques et les jeux d’acteurs sont des modalités importantes d’hybridité dans de tels projets et plus particulièrement dans les situations de médiation où l’articulation des cadres de fonctionnement et des cadres d’usage est à l’œuvre.
Communication et dynamiques d’hybridation dans les organisations de type laboratoire vivant : un regard constitutif sur le démarrage d’un living lab au service des aînés
Authors: Baillargeon Dany , Bruneau Hélène
Published: February 2020

Ancrée dans le paradigme de l’innovation ouverte, la méthodologie laboratoire vivant (living lab) met en relation chercheurs, représentants des secteurs public et privé et citoyens afin de créer des solutions innovantes à des problématiques complexes. À travers un partage mutuel de connaissances et d’expériences autour d’un but commun, ce mode d’organisation hybride suppose également de maintenir les intérêts de chaque acteur, ce qui vient avec son lot de tensions. À partir d’une analyse des figures (Cooren, 2013) animées dans des textes et des conversations entourant le démarrage d’un laboratoire vivant axé sur les enjeux du vieillissement, nous exposons différentes tensions émanant du processus d’hybridation, mais également le favorisant. Quatre enjeux sont particulièrement porteurs des tensions : le statut du laboratoire, son fonctionnement, la représentation des parties prenantes et la terminologie en usage. D’un point de vue constitutif, nous démontrons que les tensions liées à l’appartenance participent du processus d’hybridation, ce dernier étant fait de dynamiques de détachements/rattachements.
L'art de dire et de faire le goût : les médiations culturelles dans un manga culinaire
Authors: Deramond Julie , Lambert Emmanuelle
Published: February 2020

A travers l'étude monographique d'un manga spécialisé sur le vin et la cuisine (Les Gouttes de Dieu, de Tadashi Agi et Shu Okimoto), cet article analyse les questions de mise en correspondance des sens, de croisement des arts et d'interculturalité pour montrer comment s'élaborent des formes de médiations et de médiatisation des goûts culinaires, esthétiques et culturels. Le manga, considéré comme médiaculture, se fait ainsi non seulement discours sur le vin mais également passeur de formes, d'objets et de valeurs culturels, devenant prescripteur. Entre discours expert et profane, terminologies professionnelle et autodidaxique, il s'apparente alors à une forme hybride de critique œnologique. Cette bande dessinée japonaise nous invite donc à penser les processus et discours communicationnels liés à la construction du goût, œnologique et esthétique.

Published: February 2020

La conception de cartes à des fins de communication ou, de manière plus générale, la visualisation de données est un champ de recherches relativement ancien qui a subi de profonds changements au cours de ces dernières années. Si de nombreuses recherches y sont consacrées, très peu d’entre elles s’intéressent à une autre tendance forte du moment : l’emploi ou le détournement du jeu à des fins de communication. Ce papier traite de cette question en abordant le cas d’un support informationnel rappelant un jeu de stratégie sur plateau développé dans un but d’information à propos d’un nouveau procédé de lutte contre le cancer : la thérapie photodynamique.

Les Vedettes du Sport et des Médias. Introduction
Authors: Derèze Gérard
Published: February 2020

Contemporain de l’avènement du cinéma, Marcel Mauss reconnaît dans la démarche des infirmières celle des actrices américaines et repère très tôt ce que les usages sociaux doivent aux représentations qu’on en donne. Quelques décennies plus tard, Edgar Morin prolonge cette réflexion et ouvre un champ de recherche, mais depuis Les Stars, force est de constater que le sens et la place des vedettes, des héros et des idoles –que produisent nos sociétés médiatisées– suscitent des questions complexes et récurrentes. Dans ce numéro de Recherches en communication, nous tenterons de mieux comprendre le sens et de mieux identifier la place qu’occupent aujourd’hui dans les médias, parmi les vedettes du loisir ou du divertissement, les vedettes du sport.
North-South Distribution and Asymmetry of GOES SXR Flares during Solar Cycle 24
Authors: Joshi Anita , Chandra Ramesh
Published: February 2020

Here we present the results of the study of the north-south (N-S) distribution and asymmetry of GOES soft X-ray (SXR) flares during solar cycle 24. The period of study includes ascending, maximum and descending phases of the cycle. During the cycle double-peaked (2011, 2014) solar maximum has occurred. The cycle peak in the year 2011 is due to B-class flares excess activity in the northern hemisphere (NH) whereas C and M class flares excess activity in the southern hemisphere (SH) supported the second peak of the cycle in 2014. The data analysis shows that the SXR flares are more pronounced in 11 to 20 degree latitudes for each hemisphere. Cumulative values of SXR flare count show northern excess during the ascending phase of the cycle. However, in the descending phase of the cycle, southern excess occurred. In the cycle a significant SH dominated asymmetry exists. Near the maximum of the cycle, the asymmetry enhances pronouncedly and reverses in sign.
Highly porous, fast responding acrylamide hydrogels through emulsion polymerization using coconut oil
Authors: Dharmasiri Mihisirini Bhagya , Kuruwita Mudiyanselage Thilini
Published: February 2020

Conventional acrylamide hydrogel exhibits a slow swelling rate which limits its potential for novel applications. It is a formidable challenge to increase the rate of swelling and if addressed successfully, this paves new paths for significant advanced applications. Fast responding polyacrylamide hydrogels with microporous structures and an interconnected network of capillary channels have been successfully synthesized by free radical emulsion-templated polymerization (a 2.5 m acrylamide monomer solution was crosslinked with 1% N,N-methylenebisacrylamide using 5% potassium persulfate as the initiator). Virgin coconut oil (70% v/v) was used as the pore forming agent, which was dispersed in the aqueous monomer solution by using 5% non-ionic surfactant (Tween 80®). Developed porous acrylamide hydrogel displayed approximately 600 wt% water absorptivity compared to the dry weight of the sample in 15 s at 30°C. Swelling ratio and scanning electron microscopy studies uncovered the characteristic microporous structure of the hydrogel. Pores of the hydrogel are interconnected to form capillary channels and thus they are responsible for the higher swelling rate of the hydrogel.
Elder Law and Its Justifications: A Hybrid Vision Inspired by Family Law Jurisprudence
Authors: Hacker Daphna
Published: February 2020

This Article calls for a departure from the ‘positivist–professional’ definition of Elder Law. It offers a new definition that demands answers regarding the justifications for this legal area and the normative base that should guide its content. The paper draws on findings from a qualitative study with grown children who have an elderly parent in need. These findings point toward a) a preliminary theoretical framework that justifies a special area of Elder Law, embracing and transcending that of anti-ageist law, and b) the relevance of Family Law jurisprudence as a normative inspiration for this legal area.
Intergenerational Support of Older Adults by the ‘Mature’ Sandwich Generation: The Relevance of National Policy Regimes
Authors: Silverstein Merril , Tur-Sinai Aviad , Lewin-Epstein Noah
Published: February 2020

In this article we examine the association between national welfare regime and the propensity of middle–aged and older individuals with adult children of their own to provide social support to aged parents. Using data from mature adults (50+) in 26 European countries, we examine whether older and younger generations compete for the time resources of the middle “sandwiched” generation, and whether national policy context shapes this competition. Contrary to expectations, we found that sandwich generation members were less likely to provide support to their parents in Conservative–Mediterranean and East European regimes, but more likely to do so in universalistic Social–Democratic regimes. This evidence supports the hypothesis that well–developed welfare states “crowd–in” family support to older individuals. Middle generation members who provided social support to their adult children tended to provide to their older parents as well. This was particularly true in the two regimes where resources and public benefits tend to be more generous and may be interpreted as state benefits that reduce intergenerational competition. Findings are discussed in terms of the capacity of state policies to shape the allocation of family resources to older adults where extended family lineages have become the norm.
Effects of Inertial Load on Sagittal Plane Kinematics of the Lower Extremity During Flywheel-Based Squats
Authors: Worcester Katherine S. , Baker Paul A. , Bollinger Lance M.
Published: February 2020

Worcester, KS, Baker, PA, and Bollinger, LM. Effects of inertial load on sagittal plane kinematics of the lower extremity during flywheel-based squats. J Strength Cond Res 36(1): 63–69, 2022—Increasing load increases flexion of lower extremity joints during weighted squats; however, the effects of inertial load on lower extremity kinematics during flywheel-based resistance training (FRT) squats remain unclear. The purpose of this study was to evaluate sagittal plane kinematics of lower extremity joints during FRT squats at various inertial loads. Nine recreationally resistance-trained subjects (3M, 6F) completed a bout of FRT squats with inertial loads of 0.050, 0.075, and 0.100 kg·m2. Two-dimensional sagittal plane kinematics were monitored with retroreflective markers at a rate of 60 Hz. Joint angles and angular velocities of the knee, trunk + hip, trunk inclination, and ankle were quantified throughout concentric and eccentric actions. Effects of inertial load were determined by repeated-measures analysis of variance with α = 0.05. Average power and average vertical velocity decreased with increasing inertial load, whereas average force increased. Minimal and maximal sagittal plane joint angles of the knee, trunk + hip, trunk inclination, and ankle were not significantly different among inertial loads. However, peak joint angular velocities of the knee and trunk + hip tended to decrease with increasing inertial load. Conversely trunk inclination and ankle dorsiflexion velocities were not significantly different among inertial loads. Increasing inertial load from 0.050 to 0.100 kg·m2 significantly reduces average power during FRT squats primarily by decreasing movement velocity, which seems to be specific to the knee and hip joints. It is possible that lower concentric energy input at high inertial loads prevents increased joint flexion during FRT squats.

Köklü, Y, Köklü, Ö, Işıkdemir, E, and Alemdaroğlu, U. Effect of varying recovery duration on postactivation potentiation of explosive jump and short sprint in elite young soccer players. J Strength Cond Res 36(2): 534–539, 2022—The purpose of this study was to investigate the effects of postactivation potentiation (PAP) on vertical jump and sprint performances with different recovery durations. Twelve elite young soccer players (average age: 17.0 ± 0.6 years; body mass: 67.0 ± 5.4 kg; height: 175.0 ± 3.5 cm) voluntarily performed countermovement jump (CMJ) and 30-m sprints (with 10-m split times) under unloaded and 4 different recovery duration conditions (R1: 1 minute, R2: 2 minutes, R3: 3 minutes, and R4: 4 minutes) after a set of 3 repetitions of half-squat exercises at 90% of 1-repetition maximum. Electromyographic assessments of both limbs' vastus lateralis (VL) and semitendinosus (ST) muscle activity were also made during the tests. Vertical jump height, sprint time, and VL and ST muscle activity root mean square (RMS) values were analyzed. The results show that players demonstrated significantly better CMJ, 10-, and 30-m sprint performances in the R4 condition compared with the unloaded condition (p < 0.05). The players also showed significantly higher RMS values for VL and ST muscle activity in the CMJ and 30-m test performances for both legs in the R4 condition compared with the unloaded, R1, R2, and R3 conditions (p < 0.05). According to these results, if sports scientists and coaches desire to increase the PAP effect after heavy resistance training, 4 minutes of recovery time instead of 1, 2, or 3 minutes for CMJ, 10-, and 30-m sprint performances is recommended.

Scantlebury, S, Till, K, Sawczuk, T, Dalton-Barron, N, Phibbs, P, and Jones, B. The frequency and intensity of representative and nonrepresentative late adolescent team-sport athletes' training schedules. J Strength Cond Res 35(12): 3400–3406, 2021—This study aimed to identify and compare the training frequency and intensity (via session rating of perceived exertion load [sRPE load]) of representative and nonrepresentative late adolescent athletes. Thirty-six team sport athletes completed a web-based questionnaire daily over an 8-month period, reporting their training/match activities from the previous day. Athletes were categorized as representative (academy/county/international) or nonrepresentative (club/school) depending on the highest level of their sport they participated. Mean weekly frequencies and sRPE load of different training/match activities were quantified for each athlete across 5 school terms. Mann-Whitney U tests established the significance of differences and effect sizes between playing standards for mean weekly frequencies and mean sRPE load. Within-athlete weekly sRPE loads were highly variable for both playing standards; however, representative level athletes participated in significantly more activity outside of school compared with nonrepresentative athletes during November–December (effect size; 0.43—club technical training; 0.36—club matches), January–February (effect size; 0.78—club technical training; 0.75—club matches), and February–March (effect size; 0.63—club technical training; 0.44—club matches). Therefore, club and school coaches must ensure that all elements of representative athletes training schedules are coordinated and flexible to promote positive adaptions to training such as skill and physical development and prevent maladaptive responses such as overuse injury and nonfunctional overreaching. A cooperative and malleable training schedule between club/school coaches and the athlete will allow the athlete to perform on multiple fronts while also being able to meet the demands of additional stressors such as schoolwork.

Orr, RM, Robinson, J, Hasanki, K, Talaber, KA, Schram, B, and Roberts, A. The relationship between strength measures and task performance in specialist tactical police. J Strength Cond Res 36(3): 757–762, 2022—Specialist tactical police officers (STPOs) carry heavier on-body loads than generalist police officers. Improvements in strength may mitigate the impacts of these heavier loads. The aim of this investigation was to determine the correlations between absolute and relative strength measures and occupational task performance in STPOs. Retrospective data were provided for 47 male specialist police officers from an elite Australian police unit. Data included body mass (mean = 89.0 ± 8.58 kg), strength measures (1 repetition maximum measures for a bench press, squat, deadlift, and pull-up), and task performance measures (85-kg victim drag wearing 15 kg of operational load and 5-km pack march wearing 40 kg of operational load). Pearson's correlations were conducted to determine relationships between measures and were plotted on a linear regressions model. Significant, moderate to strong correlations were found between all strength measures and victim drag performance and significant negative moderate correlations between relative bench press, absolute and relative squat, and absolute and relative pull-up and pack march times. The absolute deadlift had the strongest correlation to the victim drag (r = 0.747, p < 0.01) while the relative pull-up showed the strongest correlation with pack march performance (r = −0.466, p < 0.01). The requirement to lift a portion of the dummy off the ground during the victim drag may explain the increased importance of absolute strength while the requirement to transport load affixed to the body may explain the importance of relative strength requirements. Improvements in absolute and relative upper- and lower-body strength may improve task performance in this population.

Medeiros, LHL, Sandbakk, SB, Bertazone, TMA, and Bueno Júnior, CR. Comparison of periodization models of concurrent training in recreationally active postmenopausal women. J Strength Cond Res 36(4): 977–983, 2022—Although concurrent training is the most effective way to improve both neuromuscular and cardiorespiratory functions in older populations, there are no studies in the literature comparing different periodization models on cardiorespiratory and muscle strength adaptations. Thus, the main objective of this study was to investigate the effects of different periodization models of concurrent aerobic and strength training using equalized training volume programs on muscle strength and cardiorespiratory fitness in recreationally active postmenopausal women. After 3 weeks of adaptation, 58 women aged 50–75 years were randomly assigned to (a) nonperiodization (NP), (b) daily nonlinear periodization (NLP), or (c) flexible daily NLP (FNLP). At baseline and after 12 weeks, aerobic fitness (peak oxygen uptake [V̇o
2peak] and the 6-minute walk test) and maximal muscle strength (1 repetition maximum of bench press and leg press) were measured. It was shown that maximal strength increased in the bench press (effect size [ES] 1.18 in NLP and 1.22 in FNLP) and leg press (ES 0.92 in NLP and 0.89 in FNLP) in the periodized groups—in the NP group, these values were 0.49 and 0.46, respectively. In the 6-minute walk test, aerobic fitness statistically improved in all groups—with an ES of 1.02 in the NP, 1.33 in the NLP, and 0.54 in the FNLP. This study showed that only periodization models (NLP and FNLP) induced a moderate ES in maximal strength, and all groups (NP, NLP, and FNLP) demonstrated improved aerobic fitness evaluated by V̇o
2peak and the 6-minute walk test in recreationally active postmenopausal women.

One of the problems of providing a group launch of spacecraft is to ensure the re-launch of the propulsion engine for the transition to another orbit, after the separation of the first vehicle. When the spacecraft is separated into a stage, an acceleration is applied directed toward the bottom of the tank and leading to an outflow of the fuel component from the mesh separator. This, in turn, leads to the denudation of the mesh separator and the penetration of gas under it, which can lead to a breakdown of the launch of the engine. In viewof the complexity of the hydrodynamic processes taking place in the tanks, experimental confirmation of the mesh separators chosen during the design is required.In this paper, we describe the methods for determining the model conditions (the choice of the scale of the experimental design, the type of the model fluid, the magnitude of the accelerations, etc.), a description of the stand designed specifically for the test data, and the results of the experimental confirmation of the capillary sampling device performance in the separation of the spacecraft. The results of the performed works confirm the correctness of the decisions made in the development of capillary sampling devices.

The effect of modification by refractory dispersed compositions on the grain structure and properties of welded aluminium alloys is determined. Aluminium alloys of the Al-Mg-Mn system of chemical composition were studied: 4.8-6.0% magnesium, 0.3-0.5% manganese; 0.45 – 0.90% iron; aluminium - base. The iron content corresponded to the pre-eutectic and post-eutectic compositions of the aluminium-iron system. Titanium carbide (TiC) modifier powders with a dispersion of 1-5 microns obtained by the method of plasmachemical synthesis. The microstructure of the alloys was studied using MIM-8 and Neophot-2 optical microscopes. The strength properties of the alloys were determined using the MUP-20 machine. Production of samples was carried out according to GOST 1497-84 and GOST 9454-80. Fluidity was determined by the spiral sample method. The properties of alloys before and after modification were investigated. Improved technological properties of aluminium alloys after modification. Increased fluidity in AMg5 and 1420 alloys by 1.5% and 6%, respectively. The obtained homogeneous dispersed structure of aluminium alloys after modification. The strength properties of modified alloys are increased by20 %. Experiments were conducted on the effect of the charge type on the structure and properties of technically pure aluminium and aluminium alloys AMg5 and 1420. The advantage of solid charge in the smelting of aluminium ingots in reducing porosity and grinding grain in comparison with the use of liquid charge is established.

Kabuki syndrome consists in a series of congenital anomalies involving intellectual disability, hypotonia, and facial and body dysmorphism. In addition to these cardinal signs, craniofacial and dental changes are frequently observed, although they are not fully understood. Thus, the aim of this article is to present the dental findings in patients with Kabuki syndrome. This is a systematic review developed according to the PRISMA protocol. A search strategy with descriptors ("kabuki syndrome" AND "dentistry") was applied to six databases. As inclusion criteria, we selected clinical case reports that addressed dental findings in one or more patients with Kabuki syndrome between 1999 and 2019, without restrictions regarding gender, age or language. Data collection in all databases was performed by a calibrated evaluator and titles, abstracts and full-text studies were systematically analyzed. Eleven case reports that fit the proposed inclusion criteria were found. After the qualitative synthesis, teeth absence or agenesis were the most reported findings, being observed by nine authors. Less frequent dental findings in patients with this syndrome are taurodontism, microdontia, fusion, gemination and conical or screwdriver-shaped teeth. In fact, when any syndrome or genetic condition is related to manifestations of dental interest, the dental surgeon should be able to investigate them, especially teeth agenesis or absence. For this reason, the dentist should be aware of the manifestations of Kabuki syndrome, contributing to patients' understanding and management.

Yoruba personal naming system
Authors: Fakuade Gbenga , Friday-Otun Joseph , Adeosun Hezekiah
Published: February 2020

The Yoruba, like many other ethnic nationalities in Africa, have developed personal naming traditions, practices and patterns that represent the beliefs, expectations and circumstances surrounding new births. This article examines this aspect of the Yoruba culture, set as models and practiced by members of every Yoruba speech community. It discusses the typology of Yoruba personal names by focusing on their sociolinguistic features, and the impact of Western culture, Christianity and Islam on these names. The data collected for the study were drawn primarily from participant observations and oral interviews in addition to previous studies on Yoruba personal names. Textual data were sourced from the West African Examination Council (WAEC) and the National Examinations Council (NECO) lists of Yoruba candidates and admission lists of four universities. This article is based on indexicality theory which purports that the referent of a name is determined by the context. It is revealed that these names tell stories of families’ socio-economic backgrounds, represent customs and religions, reflect dreams, as well as predict the child’s future path. Yoruba personal names, therefore, mirror their cultural norms and social imaginaries.
Onomastic strategies
Authors: Batoma Atoma
Published: February 2020

In this article I propose to analyze three verbal strategies underlying the use of personal names by the Kabye of northern Togo. Such strategies fulfill a variety of purposes, including attempts to influence the behavior of a name-bearer in the context of interpersonal or social relationships. They are often implemented with the intent to help name-bearers live up to their name. Among these strategies I examine (1) the choice of a name, (2) its intonation and (3) its amplification. All three strategies fall within the scope of the socio-pragmatic approach to naming (the giving of names as well as their use) defined here as essentially an act of interpellation.
Naming and social identity
Authors: Solomon-Etefia Patience , Ideh Amaka
Published: February 2020

Among the Awgbu Igbo people in Anambra State, South-east Nigeria, praise names are bestowed on community members as traditional identifying resources to reflect their personalities, aspirations and social being. These names are required for all adults to establish bonding, extend social relationships and strengthen feelings of solidarity within their local and translocal spaces. This study undertakes a sociolinguistic investigation of male praise names among members of the Awgbu Igbo community taking into account how the names are socially constructed to negotiate identity and authenticity. The discourse of praise names in Awgbu is analysed using social identity theory (Tajfel and Turner, 1979), which maintains that at the level of the self, a person may have multiple social identities, which widen circles of group membership, enact friendship and foster individual identity and collective belonging. We have classified praise names based on relevant social categories that reflect Awgbu life experiences. This study concludes that praise names can create a platform for group members to bond socially by offering an alternate naming enterprise which provides bearers with interactional strategies for the discursive and ideological construction of power and dominance.

RESUMO: Introdução: A comorbidade tuberculose e diabetes ainda continua um desafio para a saúde pública mundial. Objetivo: Analisar o perfil sociodemográfico e as características do diagnóstico e tratamento dos casos de tuberculose com e sem diabetes no Brasil. Métodos: Estudo transversal, com dados do Sistema de Informação de Agravos de Notificação e do Sistema de Gestão Clínica de Hipertensão Arterial e Diabetes Mellitus da Atenção Básica, no período de 2007 a 2011. Modelo de regressão de Poisson com variância robusta foi utilizado para estimar a razão de prevalência (RP) e seus respectivos intervalos de confiança. Resultados: A comorbidade estudada foi encontrada em 7,2% dos casos. Modelo hierárquico mostrou maior RP entre indivíduos do sexo feminino (RP = 1,31; intervalo de confiança de 95% - IC95% 1,27 - 1,35); maior associação nas faixas etárias 40-59 anos e ≥ 60 anos (RP = 11,70; IC95% 10,21 - 13,39 e RP = 17,49; IC95% 15,26-20,05) e com resultado positivo da baciloscopia - primeira amostra (RP = 1,40; IC95% 1,35 - 1,47). Reingresso após abandono e abandono foram inversamente associados na comorbidade (RP = 0,66; IC95% 0,57 - 0,76 e RP = 0,79; IC95% 0,72 - 0,87). Conclusão: Os achados, como a relação inversa do abandono ao tratamento da tuberculose no grupo das pessoas com comorbidade, reforçam a importância de ações integradas nos serviços para mudar o cenário dessa desafiadora comorbidade.
