Authors: López-Díaz Juan Antonio , Gómez Benigno , González-Soriano Enrique , Gómez-Tolosa María
Published: June 2021

Con el fin de evaluar la diversidad del orden Odonata y relacionarla con la calidad del ambiente, en San Cristóbal de Las Casas (Chiapas) se eligieron cuatro humedales de acuerdo con su accesibilidad y permisibilidad. Para la tipología ambiental se consideró, entre otras características, la calidad visual, estimada a través del Índice del Estado de Conservación de Humedales (IECH). Recolectas sistemáticas mensuales de los odonatos adultos fueron realizadas entre julio de 2014 y junio de 2015. Un total de 14 especies, distribuidas en cinco familias y 10 géneros fueron encontradas. El género Argia fue el de mayor riqueza, mientras que Ischnura denticollis y Enallagma rua representaron las especies dominantes. Las Cañadas, humedal con calidad visual subóptima, presentó la mayor diversidad de libélulas al integrar un ambiente lótico. El grado de alteración de la vegetación acuática, como uno de los parámetros evaluados en la calidad visual, fue muy importante en las diferencias encontradas en la diversidad y abundancia de Odonata en los cuatro humedales. María Eugenia y La Kisst catalogados como ambientes con calidad visual óptima y regular, respectivamente, obtuvieron la mayor similitud en su odonatofauna relacionada con las distintas formas de vida de su vegetación acuática y por el tamaño equivalente de estos dos humedales.
Evidence of Construct Validity of Computer-Based Tests for Clinical Reasoning: Instrument Validation Study
Authors: Zuo Tianming , Sun Baozhi , Guan Xu , Zheng Bin , Qu Bo
Published: June 2021

Background

Clinical reasoning (CR) is a fundamental skill for all medical students. In our medical education system, however, there are shortcomings in the conventional methods of teaching CR. New technology is needed to enhance our CR teaching, especially as we are facing an influx of new health trainees. China Medical University (CMU), in response to this need, has developed a computer-based CR training system (CMU-CBCRT).

Objective

We aimed to find evidence of construct validity of the CMU-CBCRT.

Methods

We recruited 385 students from fifth year undergraduates to postgraduate year (PGY) 3 to complete the test on CMU-CBCRT. The known-groups technique was used to evaluate the construct validity of the CBCRT by comparing the test scores among 4 training levels (fifth year MD, PGY-1, PGY-2, and PGY-3).

Results

We found that test scores increased with years of training. Significant differences were found in the test scores on information collection, diagnosis, and treatment and total scores among different training years of participants. However, significant results were not found for treatment errors.

Conclusions

We provided evidence of construct validity of the CMU-CBCRT, which could determine the CR skills of medical students at varying early stage in their careers.
Acceptability and Effectiveness of Artificial Intelligence Therapy for Anxiety and Depression (Youper): Longitudinal Observational Study
Authors: Mehta Ashish , Niles Andrea Nicole , Vargas Jose Hamilton , Marafon Thiago , Couto Diego Dotta , Gross James Jonathan
Published: June 2021

Background

Youper is a widely used, commercially available mobile app that uses artificial intelligence therapy for the treatment of anxiety and depression.

Objective

Our study examined the acceptability and effectiveness of Youper. Further, we tested the cumulative regulation hypothesis, which posits that cumulative emotion regulation successes with repeated intervention engagement will predict longer-term anxiety and depression symptom reduction.

Methods

We examined data from paying Youper users (N=4517) who allowed their data to be used for research. To characterize the acceptability of Youper, we asked users to rate the app on a 5-star scale and measured retention statistics for users’ first 4 weeks of subscription. To examine effectiveness, we examined longitudinal measures of anxiety and depression symptoms. To test the cumulative regulation hypothesis, we used the proportion of successful emotion regulation attempts to predict symptom reduction.

Results

Youper users rated the app highly (mean 4.36 stars, SD 0.84), and 42.66% (1927/4517) of users were retained by week 4. Symptoms decreased in the first 2 weeks of app use (anxiety: d=0.57; depression: d=0.46). Anxiety improvements were maintained in the subsequent 2 weeks, but depression symptoms increased slightly with a very small effect size (d=0.05). A higher proportion of successful emotion regulation attempts significantly predicted greater anxiety and depression symptom reduction.

Conclusions

Youper is a low-cost, completely self-guided treatment that is accessible to users who may not otherwise access mental health care. Our findings demonstrate the acceptability and effectiveness of Youper as a treatment for anxiety and depression symptoms and support continued study of Youper in a randomized clinical trial.

Analysis: The article treats infrastructure as a form of non-discursive politics and examines the critical status of the concept in light of the historical and contemporary implications of infrastructure in colonialism, settler colonialism, and racial capitalism.

Conclusions and implications: The article concludes that treatments of infrastructure in recent critical feminist, queer, and Indigenous thought open new possibilities for rethinking politics, communication, and media.
Mediating the Tree: Infrastructures of Pulp and Paper Modernity inThe Bowater Papers
Authors: Kaminska Aleksandra , Ruiz Rafico
Published: June 2021

Background: Through a close reading of the four issues of The Bowater Papers, this article aims to understand the rise of a paper modernity and to reinsert it—as material and infrastructure—into media studies.

Analysis: Producing wood paper is a strain on the landscape and the environment. The Bowater Papers showcases the histories and material possibilities of paper media products. A paper-dependent modernity can be understood as an infrastructural assemblage of harvesting, production, circulation, and consumption.

Conclusion and implications: Paper calls for a natural history and geography of media. Thinking about the mediations from tree to paper through the encompassing notion of “xylomedia” is a way of articulating the intersection of the material, environmental, and infrastructural in media studies. Today is still a paper world, one that is also the age of lignin, package, and Amazon.

Published: June 2021

La pielonefritis enfisematosa es una enfermedad grave y de alta mortalidad, pero de baja frecuencia, que suele presentarse en población con factores de riesgo, dentro de los que destacan la diabetes mellitus tipo 2, la uropatía obstructiva, el etilismo y la inmunosupresión. La clasificación radiológica de la pielonefritis enfisematosa va desde clase 1, que comprende el gas que compromete el sistema colector, hasta clase 4, que es la afección de un solo riñón o bilateral. El tratamiento de la pielonefritis enfisematosa depende del grado de severidad: los casos más leves pueden tratarse con catéter o drenaje percutáneo más terapia antibiótica, mientras que los más graves pueden necesitar intervención quirúrgicapara nefrectomía. Aquellos pacientes con choque séptico, trombocitopenia, insuficiencia renal aguda e hipoalbuminemia generalmente tienen pronóstico desfavorable. A continuación, se presentan dos casos de pacientes diabéticos mal controlados mayores de 50 años de edad, quienes fueron diagnosticados a través de estudios imagenológicos. Uno de los pacientes tenía uropatía obstructiva y el otro, riñón en herradura; ambos fueron tratados exitosamente con manejo médico y procedimiento mínimamente invasivo.

Published: June 2021

El síndrome de la bolsa de orina púrpura es una condición clínica de prevalencia desconocida en Colombia debido al escaso reporte de casos a nivel nacional. Esta entidad se presenta exclusivamente en pacientes portadores de sonda vesical con factores de riesgo asociados como enfermedad renal crónica, patologías neurológicas, residentes de hogares geriátricos, sexo femenino, entre otros. La coloración púrpura de la orina se da en un ambiente urinario alcalino propiciado por bacterias específicas, en donde se genera una reacción de oxidación del indoxil sulfato en índigo e indirrubina por acción de las enzimas fosfatasas/sulfatasas de estos microorganismos, dichos pigmentos se mezclan generando la coloración púrpura en la bolsa urinaria. Se reporta el caso de un paciente masculino de 75 años con un cuadro clásico de síndrome de la bolsa urinaria púrpura, con el propósito de ampliar el conocimiento en la literatura nacional vigente. Adicionalmente, con esta publicación se busca que los profesionales de la salud comprendan los mecanismos fisiopatológicos por los cuales se produce esta entidad para saber abordarla apropiadamente.

Authors: Ahmed Nusrat , Akter Jesmin , Archie Sabrina Rahman
Published: June 2021

Since orally disintegrating tablets (ODTs) of tramadol hydrochloride are not available in the market, so an attempt has been taken to formulate and evaluate ODT preparation of tramadol hydrochloride. In this present work, direct compression was the technique used for preparing ODT using superdisintegrants like croscarmellose sodium, sodium starch glycolate and crospovidone at different concentrations. Prepared formulations were evaluated for various quality parameters- angle of repose, Carr’s index, Hausner ratio, weight variation, friability, hardness, drug content, dispersion time, wetting time and in-vitro dissolution. The angle of repose data indicated that the flow property of all the formulations was good to excellent. Comparing with the specifications, the results of Carr's index (%) and Hausner’s ratio indicated that the flowability of all the formulations blend was significantly good. Prepared formulations showed average wetting time ranging from 40-45 seconds, average dispersion time with 3-6 minutes. In-vitro dissolution profile indicated the cumulative % drug release between 30-80% for most of the cases.
Keywords: Orally disintegrating tablets, Tramadol hydrochloride, Superdisintegrants, Direct compression.
A Call for Point-of-Care Ultrasound Fellowship Training Programs for General Internal Medicine in Canada
Authors: Wiskar Katie , Ma Irene , Arishenkoff Shane , Arntfield Robert
Published: June 2021

Point-of-care ultrasound (POCUS) offers numerous benefits and is recognized as an important competency within Internal Medicine (IM). Despite this, a significant educational gap exists, owing in large part to a lack of expertly trained faculty and structured training opportunities. A robust POCUS training program requires not only technical excellence among faculty but also leadership with expertise in program creation and administration, quality assurance, medical education, and research. A dedicated 6- to 12-month POCUS fellowship model in programs with well-established infrastructure allows for the development of these competencies and the establishment of a network of key POCUS contacts, and prepares trainees to create or expand POCUS programs at their centers. We propose that the expansion of dedicated General IM POCUS fellowships in Canada is imperative to addressing this educational bottleneck and shaping the future leaders of Canadian IM POCUS.
RésuméL’échographie au point d’intervention (POCUS) offre de nombreux avantages et est considérée comme une compétence importante en médecine interne. Pourtant, il existe une lacune importante au chapitre de la formation, attribuable en grande partie au manque d’enseignants qualifiés et d’occasions de formation structurée. Un programme de formation solide sur la POCUS exige non seulement une excellence technique parmi le corps professoral, mais aussi un leadership démontrant une expertise dans la création et l’administration de programmes, l’assurance de la qualité, l’éducation médicale et la recherche. Un modèle de formation complémentaire de 6 à 12 mois consacrée à la POCUS dans des programmes dont l’infrastructure est bien établie permet d’acquérir ces compétences et d’établir un réseau de personnes-ressources clés sur la POCUS, et prépare les personnes en cours de formation à créer ou à élargir des programmes sur la POCUS dans leur centre. Nous proposons qu’il soit impératif d’élargir les formations complémentaires sur la POCUS en médecine interne générale au Canada pour remédier à ce goulot d’étranglement en matière de formation et façonner les futurs chefs de file de la POCUS en médecine interne au Canada.

A festa do caboclo Truvezeiro, realizada no terreiro Ilê axé Akaraizô, é interessante motivo para uma imersão visual fotográfica e etnográfica em contexto urbano, em âmbito religioso urbano. Os processos de interação corporal (pela necessidade de se movimentar no barracão para realizar registros fotográficos) e visual (para entender sinalizações de permissão ou não para fotografar em determinados momentos do ritual) tanto quanto o gancho possibilitado para se pensar sobre as relações entre a religião, candomblé, e o culto ao caboclo, são de interesse antropológico.Palavras-chave: antropologia urbana. antropologia visual. fotoetnografia. religiosidade. festa de caboclo.
Possibilidades do desenho à mão na etnografia urbana: estudo de caso em Florianópolis/SC
Authors: Ruchaud Guilherme , Alfonso Louise Prado
Published: June 2021

Este ensaio traz reflexões sobre o lugar ocupado pelo gesto do desenho durante um trabalho etnográfico na cidade, abrangendo desenhos de observação e aqueles feitos a posteriori, e algumas possibilidades de pensar a inserção dessa prática na etnografia. A partir de uma experiência particular de uma inserção de campo feita durante minhas pesquisas de TCC em Arquitetura e Urbanismo, e depois de dissertação de mestrado em Antropologia, buscamos interpretar uma seleção de desenhos autorais desenvolvidos em diferentes momentos e o papel que podem ter tido na construção do trabalho etnográfico em questão, desenvolvido em Florianópolis entre 2015 e 2019. A partir dessa experiência propomos algumas reflexões e apontamentos que podem compôr um debate mais amplo no campo da metodologia em Antropologia e nas Ciências Sociais aplicadas, situando o lugar do desenho como, mais do que registro e representação, parte de um processo de produção de sentido a partir da inserção e revisita a campo.
O lugar de encontro nas praças públicas do DF: as intervenções artísticas pelos afetos
Authors: Figueiredo Lorena Da Silva , Freitas Gabriela
Published: June 2021

A partir de uma reflexão sobre a Praça do Povo (Brasília – DF) e da Praça do Cidadão (Ceilândia – DF), o artigo pretende fazer associações entre os saberes filosóficos, sociais e arquitetônicos que se unem na compreensão da produção de subjetividades das intervenções artísticas. O aporte teórico da “partilha do sensível”, de Jacques Rancière, nos ajuda a pensar sobre um conjunto comum partilhado pela via dos afetos. Como metodologia, utilizamos uma cartografia social que abrange o conceito de corpo, proposto pela filosofia de Spinoza, e assim vemos como resultado a tomada de consciência do espaço público no tecido urbano que pertence à população, e não à esfera privada. As praças mencionadas, neste sentido, são pensadas como um lugar de encontro proporcionado pela atuação deste espaço público em decorrência das interações entre as pessoas e o meio urbano.Palavra-chave: Afeto. Espaço urbano. Praça do Povo. Praça do Cidadão. Subjetividades.  MEETING PLACE IN PUBLIC SQUARES ON THE FEDERAL DISTRICT: THE ARTISTIC INTERVENTIONS BY AFFECTIONS Abstract: Through the analysis about the People Square (Brasília) and Citizen Square (Ceilândia), the article has been associating with Philosophy, Social Studies and Architecture knowledge to understand the production of subjectivities for artistics intervention. The theoretical contribution is related to an idea of “distribution of the sensitive” of Jacques Rancière to think of a common set shared by means of affection. As methodology we have used Social Cartography to include the idea about the body proposed by Spinoza Philosophy. Then, as a result, to be aware of public space as urban fabric that belongs to the population and not to the private sphere. The squares mentioned are thought of as a meeting place provided by the performance of this public space by interactions between people and the urban environment.Key words: Affection. Urban space.

As Flanâncias Urbanas de Sophie Calle: Reflexões entre público e privado
Authors: Garcia Carolina Gallo
Published: June 2021

Neste artigo, apresento a obra da artista francesa Sophie Calle (1953 - presente) como um vetor para investigação acerca do espaço público, indagando o papel que as práticas artísticas críticas (Mouffe, 2013) podem desempenhar no questionamento da pressuposição democrática de tais espaços a partir dos conceitos de dissenso, aqui compreendido enquanto racionalidade política não consensual, e da partilha do sensível, que nos permite vislumbrar potencialidades da arte enquanto ferramenta política (Rancière, 1996; 2009). A partir das obras Suíte Veneziana (1980), The Detective (1981), The Address Book (1983), The Bronx (1980), Phone Booth (1994) os conceitos de dissenso e partilha do sensível serão articulados para análise das imagens e à luz dos registros textuais da artista sobre estes trabalhos.Palavras-chave: Sophie Calle; Flânerie; Performance Urbana; Partilha do Sensível; Dissenso.  SOPHIE CALLE’S FLÂNERIE: REFLECTIONS ON PUBLIC AND PRIVATE SPACESAbstract: In this article, I present the artwork of the French artist Sophie Calle (born 1953) as a medium to investigate the public space, inquiring which role that critical art practices (Mouffe, 2013) can play in questioning the assumption of democracy given to public spaces from the concepts of dissent as a non-consensual political rationality, and the distribution of the sensible, which allows us to glimpse the potential of art as a political tool (Rancière, 1996; 2009). From the artworks Suite Venetienne (1980), The Detective (1981), The Address Book (1983), The Bronx (1980) and Phone Booth (1994), the concepts of dissent and distribution of the sensible will be articulated for the analysis of images and the artist's textual records of these artworks.Keywords: Sophie Calle; Flânerie; Urban Performance; Distribution of the Sensible; Dissent.
Resistência Individual e Memórias Coletivas em Álbuns Fotográficos no Poço da Draga/Fortaleza-CE

Published: June 2021

A partir de uma ação de extensão intitulada Fotobiografias: a Fortaleza que se encontra em acervos fotográfico pessoais, buscamos refletir sobre como a partir de fotografias podemos desvelar as biografias individuais, mas também a biografia de uma cidade. A ação é realizada no Poço da Draga. Tomamos esse território a partir das fotografias que as pessoas guardam em suas casas e escutamos suas narrativas. As fotografias promovem aparições, evocam narrativas, acionam lembranças, interligam relações. Podemos tomar essas paisagens narrativas como patrimônios da cidade? Como podemos a partir da memória, refleti-las como “espaços da recordação”, que nos permitem repensar a própria leitura social, histórica e antropológica da cidade? Desta forma, partimos das narrativas de Dona Zenir, uma das moradoras mais antigas do lugar. A partir de suas narrativas e imagens ela nos leva às pessoas, às suas vivências, aproxima-se das vivências compartilhadas com outras mulheres, e costura, através da memória, o Poço da Draga à história de Fortaleza.Palavras-Chave: Biografias.

The activity takes place in Poço da Draga. We approach this territory through photographs that people keep in their homes and the narratives they tell about them. The photographs evoke narratives, activate memories, interconnect relationships. Can we consider these narrative landscapes as heritage of Fortaleza? How can we think about them as “spaces of remebrance” that allow us to reconsider social, historical and anthropological readings of the city? We take as a starting point the narratives told by Dona Zenir, one of the oldest residents of Poço da Draga. Her narratives and images take us to people, their lives, bring us closer to the lived experiences shared with other women, entwining – through memory – Poço da Draga to the history of Fortaleza.Key words: Biographies.

Published: June 2021

Objective: Diabetes is one of the most common chronic disease that
requires comparatively more care to achieve optimal therapeutic
outcomes. The aim of this study was to study the impact of pharmacist
intervention on glycemic control of type 2 diabetes patients in a
tertiary care hospital. The objectives were: To assess the parameters of
glycemic control namely FBS, PPBS, and HbA1c; To provide patient
education to one group of patients while other group of patients get
standard care; To assess the impact of the educational intervention on
blood sugar levels and HbA1c. Materials and methods: It was hospital
based prospective interventional study carried out in the general
medicine out-patient department of St. Philomena’s hospital, a tertiary
care hospital, in Bangalore, India. The patients recruited were divided
equally and randomly into control and intervention groups. Patients in
the interventional group received patient informational leaflets, and
education in addition to standard treatment, while the control group
patients received only standard treatment. Parameters of glycemic
control namely FBS, PPBS, and HbA1c of the patients were measured at
baseline and at the end of the follow up period of 3 months and compared
using appropriate statistical tests. Result: 50 patients having HbA1c
value of >8% were included in the study. FBS, PPBS, and
HbA1c values of all patients were measured at baseline and compared to
the values obtained at the end of the follow up period, and was found to
be statistically significant (p < 0.05). The difference in the
baseline and follow up values between the control and intervention
groups was also compared and found to be statistically significant
(p< 0.05). Conclusion: It was observed from our study that
pharmacist led educational intervention program for the management of
type 2 diabetes had a positive impact in lowering the levels of glycemic
parameter.
Derived Storage Allocation Rules to Meet Shared Water Demands for Optimal Operation of an Inter-basin Multi-reservoir Water Supply System
Authors: Wan Fang , Wang Yu , Xiao Lingfeng , Chai Qihui
Published: June 2021

The priority principle of storage allocation rules of serial cascade
reservoirs within an inter-basin water supply can reduce water loss and
reduce water supply times. Reasonable balancing curves for reservoirs in
parallel are proposed and the proportional distribution of water is
determined to illustrate the optimal allocation rule for different
scheduling periods of reservoirs. The mutation point and slope are used
to describe the segmentation of reservoirs in parallel. In addition, the
optimization model is established with the objective function to
minimize times of water shortage while the particle swarm optimization
algorithm based on the immune evolutionary algorithm is applied to
calibrate the balancing curves. Finally, the relative optimal water
supply rule is obtained, providing a larger water supply capacity and
higher storage synchronization of member reservoirs. The reservoir
groups downstream of Luan River are used as an example, with the results
showing that the suggested method can effectively improve the
operational performance and meet shared water demands in an inter-basin
multi-reservoir. This article highlights the superior results obtained
compared to the current storage allocation rules to meet shared water
demands.

Authors: Kirk Frazer , Eng Lim , Yadav Sumit
Published: June 2021

The introduction of Transcatheter Aortic Valve Implantation (TAVI) has
transformed interventional cardiology and minimally invasive cardiac
surgery. TAVI is a relatively new technique that is rapidly expanding in
its indications and technology as well as places of practice.
De-centralisation of this previous supra-specialised procedure can be
done safely and efficaciously, to improve the health inequalities across
regional and remote Australia. The purpose of this study is to detail
the introduction of the TAVI program at a geographically isolated
tertiary hospital in regional Australia. Illustrating the safe
introduction of TAVI in this location may guide other isolated hospitals
on the introduction of the service.

Authors: Frumkin David , Mattig Isabel , Al-Daas Maamoun , Laule Nina-Maria , Canaan-kühl Sima , Knebel Fabian , Stangl Karl , Brand Anna
Published: June 2021

Background ‘Classical’ echocardiographic signs of Fabry cardiomyopathy
(FC), such as left ventricular hypertrophy (LVH), posterolateral strain
deficiency (PLSD) and papillary muscle hypertrophy may have a limited
diagnostic accuracy in clinical practice. Our aim was to evaluate the
diagnostic value of left atrial (LA) strain impairment compared to
‘classical’ echocardiographic findings to discriminate FC. Methods In
standard echocardiographic assessments, we retrospectively analyzed the
diagnostic value of the “classical” red flags of FC as well as LA
strain in 20 FC patients and in 20 subjects with other causes of LVH.
Receiver operating characteristic (ROC) curve analysis was performed to
assess the respective diagnostic accuracy. Results FC was confirmed in
20 patients by genetic testing. In the LVH group, 12 patients were
classified by biopsy to have hypertrophic cardiomyopathy, two had
hypertensive heart disease, and six LVH combined with borderline
myocarditis. Global and regional left ventricular (LV) strain was not
significantly different between groups while LA strain was significantly
impaired in FC (Left atrial reservoir strain (LASr) 19.1%±8.4 in FC and
25.6%±8.9 in LVH, p=0.009; left atrial conduction strain (LAScd)
-8.4%±4.9 in FC and -15.9%±8.4 in LVH, p<0.01). LAScd, with
an area under the curve (AUC) of 0.81 [95% confidence interval (CI)
0.66-0.96] showed the highest diagnostic accuracy to discriminate FC.
The PLSD pattern showed an AUC of 0.49, quantification of papillary
muscle hypertrophy an AUC of 0.47. Conclusion Adding LA strain analysis
to a comprehensive echocardiographic work-up of unclear LVH may be
helpful to identify FC as a possible cause.
Assessing learning styles through eye tracking for e-learning applications
Authors: Nugrahaningsih Nahumi , Porta Marco , Klasnja-Milicevic Aleksandra
Published: June 2021

Adapting the presentation of learning material to the specific student?s characteristics is useful to improve the overall learning experience and learning styles can play an important role to this purpose. In this paper, we investigate the possibility to distinguish between Visual and Verbal learning styles from gaze data. In an experiment involving first year students of an engineering faculty, content regarding the basics of programming was presented in both text and graphic form, and participants? gaze data was recorded by means of an eye tracker. Three metrics were selected to characterize the user?s gaze behavior, namely, percentage of fixation duration, percentage of fixations, and average fixation duration. Percentages were calculated on ten intervals into which each participant?s interaction time was subdivided, and this allowed us to perform time-based assessments. The obtained results showed a significant relation between gaze data and Visual/Verbal learning styles for an information arrangement where the same concept is presented in graphical format on the left and in text format on the right. We think that this study can provide a useful contribution to learning styles research carried out exploiting eye tracking technology, as it is characterized by unique traits that cannot be found in similar investigations.
Vital Bleaching Influences the Bond Strength of Adhesive Systems to Enamel and Dentin: A Systematic Review and Meta-Analysis ofIn VitroStudies
Authors: Savian TG , Oling J , Soares FZM , Rocha RO
Published: June 2021

Objective:

This systematic review evaluates the influence of vital bleaching on the bond strength of adhesive systems to enamel and dentin.

Methods:

This review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA). In vitro studies comparing the bond strength of bleached and unbleached enamel and dentin were searched at the electronic databases—PubMed/MEDLINE, Scopus, and Web of Science—with no limit on year or language. The studies were screened and had data extracted by two reviewers independently. Bond strength data were meta-analyzed using the inverse variance method and the random effect model (p≤0.05).

Results:

The electronic search provided 4941 eligible studies, and 52 were included in the systematic review and the meta-analysis. The global meta-analysis showed that bleaching impairs the bond strength of adhesive systems to enamel and dentin (p<0.001; mean difference [MD]: −0.96; confidence interval [CI]: −1.18 to −0.73), regardless of the bleaching agent (p<0.001; MD: −9.98; CI: −1.37 to −0.58) or substrate (p<0.001; MD: −0.89; CI: −1.12 to −0.66). The detrimental effect of bleaching on bond strength was not observed after two and three weeks after bleaching (p=0.1; MD: −0.39; CI: −0.84 to 0.65; and p=0.18; MD: −0.99; CI: −2.45 to 0.47, respectively).

Conclusion:

This systematic review and meta-analysis demonstrated that vital bleaching impairs the bonding of adhesive systems to enamel and dentin, and this adverse effect persists for two weeks.
