Performances of low frequency impact sound in wooden buildings
Authors: Hagberg Klas , Bard Delphine
Published: December 2023

Since 1999 Sweden has required an extended frequency range for sound insulation in residential buildings, using 50 Hz as the lower limit. This regulation update has driven the design and development of multi storey residential building systems with wooden structures in a positive direction.
Already in the mid 1980'ies there existed scientific proof that it the perceived impact sound will improve if the frequency range was extended below the lower standard limit 100 Hz at that time. Lately, researchers have indicated that the perceived impact sound can be even further improved
if the frequency range is extended below current lower standardized limit of 50 Hz. Assume that the frequency range for impact sound requirement will be further extended to include frequencies from 25 Hz, what would that mean for modern wooden apartment buildings? Acouwood and Kuster &
Partner AG are collecting data from 20 Hz, no matter if the standard measurement procedure cannot be applied below 50 Hz. It gives a good overview of potential annoyance risk but also of acoustic performances of modern sustainable multifamily buildings and how they can be improved. This paper
summarizes measurement results of impact sound from 20 Hz in several wooden buildings.
Revision of stand alone standard, ECMA-418-1 for the detection of prominent discrete tones using tone-to-noise ratio method and prominence ratio method
Authors: Kimizuka Ikuo
Published: December 2023

In 2020 December, ECMA-418-1 1st edition was published as a stand alone and dedicated standard that specifies two parallel detection methods for prominent discrete tones in noise emitted by Information Technology and Telecommunication Equipment. The two parameters are, so called, tone-to-noise
ratio (TNR) and prominence ratio (PR), which were developed in an informative annex of ECMA-74, in 1980's and 1990's respectively. The 1st edition of ECMA-418-1, December 2020 was derived from ECMA-74:2019, Annex D. The 2nd edition was subsequently developed as minor revision, in 2022 December.
And, the 3rd edition is planned for the end of 2023. This paper reviews the history of the technical challenges in the standardization both of TNR and PR, and mentions the standardization (clarification) of terminology planned for the third edition and other issues. In addition, differences
from the similar standard, ISO/PAS 20065 etc. that were compared and contrasted during this standardization processes are also mentioned.

Published: December 2023

Infrasound carries information useful for detecting a strong natural phenomenon such as volcanic eruption and tsunami, which may cause catastrophic disaster. Therefore, infrasound measurement is gathering attention for potential applications in disaster prevention and life protection.
However, the methodology of its measurement has not been well established except a few specific applications such as Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO). Some sensor devices employ Micro Electro Mechanical Systems (MEMS) sensors, which are, in general, small and available
at a low price. This advantage enables us to increase the number of locations where infrasound can be monitored at multiple observation points. Another attempt is to assemble multiple sensors of different characters for widening dynamic range and frequency coverage of the sensor. These progress
in infrasound measurement would make it possible to utilize infrasound in various purposes. In this respect, infrasound measurement needs to be standardized because one may want to analyze infrasound data together with those acquired using different devices by other organizations. At the same
time, a platform for sharing infrasound data is becoming important to accelerate such usage. This paper overviews recent development of sensor devices for infrasound measurement and sensor deployment on going in Japan.
Non-intrusive Speech Intelligibility Prediction Method for Reverberant Speech Using Neural Network-Based Frequency Segmentation and Masking Front-end
Authors: Nakazawa Kazushi , Kondo Kazuhiro
Published: December 2023

In conventional non-intrusive speech intelligibility estimation, reverberation is extracted from the time-frequency representation of the input by explicit filter bank processing or spectral masking. However, these filter banks and masking processes are not always optimal. We replaced
these processes with convolutional neural networks using rectangular kernels restricted to the frequency direction and masking such as a self-attention mechanism. We believe that this will enable feature extraction that is optimal for intelligibility estimation and will enable its estimation
with high accuracy that generalizes well to input under various conditions. We further applied this front-end CNN to a previously proposed prediction model using speech enhancement. As a result, the estimation accuracy was improved compared to conventional front-ends using fixed filter banks,
and this prediction showed a correlation coefficient with the subjective evaluation of 0.84 compared to 0.80 with the fixed filter bank.
Current Performance of Floor Impact Sound Insulation in Wooden Apartment Buildings in Hokkaido
Authors: Hirota Tomohito
Published: December 2023

In Hokkaido, Japan, technological developments have been introduced to improve the floor impact sound insulation performance in wooden apartment buildings. However, such technological developments are not widely used, especially in rental properties. To effectively disseminate the required
technology, it is vital to report examples of implementation. Therefore, we measured the performance of five types of wooden apartment buildings with high sound insulation performance and analyzed the results. The main results are listed below. (1) A relatively high performance was obtained
by installing a floating floor and an independent ceiling. (2) For heavy weight floor impact sound insulation of a car tire source, a floating floor with a surface density of 60 kg/m2 or higher could achieve a performance of Li,Fmax,r,H(1)-60 or higher. However, in the case of a rubber ball
source, vibration radiation noise from the wall surface of the lower floor is large, so it is necessary to consider vibration countermeasures. (3) For light weight floor impact sound insulation, sufficient performance cannot be obtained even with a floating floor. Therefore, carpet or wooden
soundproof flooring should be used. (4) The light weight floor impact sound pressure level is high when the floor area of the sound receiving room is small.
Development of ventilation and sound insulation materials by the multi-objective optimization
Authors: Kajitani Keigo , Sawada Kiichiro , Nguyen Thu Lan , Trieu Bach Lien
Published: December 2023

Natural ventilation-based houses in tropical countries often suffer from poor acoustic performance. To address this issue, we developed ventilation and sound-absorbing materials using a multi-objective optimization program. The program was developed to design test specimens that optimize
the sum of the flow velocities of all elements of the divided cylindrical 3D model for sound-absorbing ability and the sum of the flow velocities in the bottom elements of the model for ventilation ability, with the objective of maximizing both. By outputting the specimens using a 3D printer,
we were able to select materials suitable for the installation environment without requiring individual design changes. In this report, we focus on improving the sound insulation rate by refining the objective functions used to create the specimens. We measured the transmission loss using
a self-made impedance tube and the 4mic method and verified the validity of our programming results by comparing them with those of laboratory experiments. Our approach has the potential to improve the acoustic performance of natural ventilation-based houses in tropical countries, making them
more comfortable and conducive to living and working.

Published: December 2023

Within the joint research project "Real-time Calculation, Auralization and Visualization of Sound Propagation and Noise Protection Measures for Infrastructure Projects" (EAV-Infra), funded by the Federal Ministry for Economic Affairs, the potentials of digital infrastructure
planning based on Building Information Modeling (BIM) and the auralization of different states of planning will be combined. In this contribution, the objectives of the project will be presented with particular focus on the auralization. Currently, the effectiveness of noise mitigation measures
like acoustic barriers or rail dampers is evaluated and communicated mostly by means of SPL values. Through auralization, a more vivid impression of different states of planning can be given during the whole planning process. In EAV-Infra, the auralization will be based on audio data of partial
sound sources taken from real train passings. The data will be collected at various sites using a newly developed MEMS microphone array. To achieve a realistic hearing impression at the receiver position, a suitable model of the sound propagation will be implemented, which allows for a simulation
in real time. In a last step, the partial sound source's signals will be convolved with the calculated sound propagation to synthesize the signal at the receiver position.
Vibroacoustic simulations of asymmetric tapered duct mimicking cochlear hydrodynamics
Authors: Lakhmani Vikas Kumar , Ramdas Rahul , Ramamoorthy Sripriya
Published: December 2023

Upon excitation by two pure-tone closely spaced in frequency, the cochlea produces intermodulation distortion tones which can be measured at the ear canal as otoacoustic emissions (OAE). Although OAEs have been widely used in auditory diagnosis, their mechanism of generation and backward
propagation are not well-understood. It is known that sound stimulation elicits two types of intracochlear pressure waves: the fluid-borne compression wave, which travels at the speed of sound and the fluid-structure coupled traveling wave, which propagates significantly slowly, especially
as it approaches the best place. However, compression wave excitation of the cochlear structures, such as the basilar membrane (BM), has been questioned on the basis of the classical Peterson-Bogert model. This question has significant implications for identifying the mechanism of backward
propagation of OAE. To address this question, vibroacoustic simulations are performed in this study in symmetric and asymmetric tapered ducts mimicking the passive human cochlea with the objective of clarifying how compression wave can excite the BM. The two ducts are separated by BM without
restricting its number of radial modes. The details of compression wave excitation of the BM are shown up to very high frequencies, and insights on this interaction are brought out.

Published: December 2023

Soundscape of urban public green space plays an important role in urban green space sightseeing experience, but it is not clear whether there are differences in soundscape diversity of different urban green space. This study investigated soundscape diversity of 30 urban green space
samples, including urban park green space, roadside green space, square green space, campus green space and residential green space. The results showed that there are differences in soundscape diversity of urban different public green spaces. In campus green space, soundscape diversity and
soundscape perceived affective quality are closely related, while in urban parks and roadside green space, soundscape diversity and soundscape perceived affective quality are not significantly related. The linear regression of soundscape diversity indices and overall quality evaluation of
soundscape fit well in campus green space, square green space and residential green space. The R2 of these regression equations were 0.65, 0.74 and 0.63, respectively. This study provides potential ideas for the design and management of urban different public green spaces in the future.
Evaluating emotionalizing effects of active sound designs
Authors: Petersen Manuel , Zaimovic Mesud , Albers Albert
Published: December 2023

Numerous results in the field of musicological research and traffic psychology research show that emotions can be altered by certain sets of pitches or sound characteristics, and emotions on the other hand influence our driving behaviour. Regardless, there is no research on how different
artificial vehicle sounds could influence the driving behaviour via emotions. We want to create an active sound design that can alter the driver's emotions to increase traffic safety in certain driving scenarios. To evaluate which harmonic compositions and sound characteristics could be used
as stimuli, we first extracted sound characteristics from different music pieces or sounds that have a proven emotionalizing effect, and generated new sounds based on said characteristics that also could work in the context of an active sound design for electrical vehicles. With these sounds,
we conducted a subject study with 45 participants to evaluate if people perceive the intended emotions, and further determine the best sounds to use in future subject studies to evaluate their impact on drivers' behaviour. This paper describes the extracted sounds, their characteristics and
psychoacoustical properties. Furthermore, it discusses the correlation between the sound properties and the perception of and emotional effect on the subjects.
Inertial amplification plates for low-frequency sound and vibration reduction
Authors: Xi Chenyang , Mi Yongzhen , Yu Xiang
Published: December 2023

Reduction of vibration and sound radiation in the low-frequency range is a challenging task. In this work, a lever-type inertial amplification (LIA) mechanism is proposed to enhance the vibration reduction capability of thin plates. The mechanism consists of a rigid lever hinged on
the host plate at two separate locations and a small mass mounted at the end of the lever. Band-structures of the unit cell and vibration transmissibility of the finite LIA plate are computed using the finite element method. Numerical results show that compared with the local resonant (LR)
plates with the same added mass, the proposed LIA plates generate wider and deeper complete bandgaps at the same target frequency. The Bragg bandgaps occurring at higher frequencies are also broader compared with those of the LR plates due to a stronger impedance mismatch between the host
plate and the attachments. Moreover, the vibration reduction performance of the LIA plate presents unique direction-dependent characteristics: maximum vibration attenuation is achieved when the LIA mechanisms are installed parallel to the wave propagation direction.

Authors: Hyodo Shinya , Yamashita Yu , Kobayashi Masahito , Morinaga Makoto , Yasuda Yosuke
Published: December 2023

To improve the floor impact sound insulation performance of cross laminated timber (CLT) buildings, a box-type test chamber made of CLT was constructed, and the countermeasure using a dry-type double floor was investigated. Several specimens with different area density and bending stiffness
of double flooring structure were prepared, and the materials of flooring and elastic floor posts were adjusted so that the natural frequency of each specimen was about 14 Hz when the specimen was considered as a single-degree-of-freedom system. The dry-type double flooring structure affected
the response at the natural frequencies not only of the slab but of walls. When installing the dry-type double flooring structure, the influence of acoustic radiation from the ceiling surface was relatively high at lower frequencies, while at higher frequencies, the influence from the walls
was relatively high. The installation of the dry-type double flooring structure resulted in an improvement in floor impact sound insulation performance.
Influence of dimensional and connection characteristics of CLT building elements on predictive calculations
Authors: Bella Antonino Di , Barbaresi Luca , Possenti Vincenzo Pettoni
Published: December 2023

The ISO 12354-1 standard provides different calculation methods for evaluating lateral transmission depending on the vibroacoustic behavior of building structures; the standard classifies them into types A and B depending on whether the structural reverberation time of the considered
element depends or not on the connecting elements. Although some construction elements are composed of the same material, they can belong to the first or second type, according to the technology of assembly or installation. CLT panels, generally belonging to type A, may sometimes behave as
type B elements. This study deals with some of these cases through calculation examples based on experimental data collected on a real-scale building mockup.
A study on soil propagation mechanism of traffic-induced vibration based on numerical analysis and theoretical approach
Authors: Sekiguchi Toru , Ishida Riei
Published: December 2023

In order to clarify soil propagation mechanism of traffic-induced vibration, soil surface responses excited by vertical and horizontal force focused on the frequency characteristics are examined based on numerical analyses, theory of surface wave, and field observations. Relationships
between natural frequency of surface soil and frequency at which wave with large amplitude propagates at distant points are examined. In the case of two-layer soil, vertical displacement amplitude excited by vertical point force becomes the largest at twice the natural frequency at distant
points. Horizontal displacement amplitude excited by horizontal point force becomes the largest at the natural frequency at distant points.

Published: December 2023

Friction induced brake squeal problem is not solved comprehensively despite several proposed theories about its mechanisms, and being frequently studied. Therefore, this study aims to make contribution to the relevant literature by obtained experimental data and built mathematical model.
Firstly, experimental modal analysis of the brake disc, caliper, bracket and pads, are performed. Afterwards, disc and pads, which have critical roles in squeal mechanism, are numerically modelled by using finite element methods. Then, model updating is performed to reach good correlation
between the experimental and computational resonant frequencies. Afterwards, high amount of brake squeal experiments are conducted by altering disc velocity, brake pressure and temperature on a laboratory set-up by acquiring sound pressure and acceleration data. Additionally, operational deflection
shape analysis is executed on the system, during selected operation conditions. Lastly, a mathematical model, which focuses on the interactions between the disc and pad, is developed to explain squeal induction mechanisms that observed in the experiments. Experiments and mathematical model
shows good agreement. It is concluded that the squeal dynamics and frequencies are depended on changing contact stiffness between the disc and pad due to changing brake pressure, and closely related to natural frequencies of the disc and caliper fingers.
Real-time sound field separation of multiple unsteady rotating loading sources
Authors: Xu Ying , Zhang Xiao-Zheng , Zhang Yong-Bin , Bi Chuan-Xing
Published: December 2023

This paper proposes a sound field separation technique based on the time-domain equivalent method for real-time separating the pressure field belonging to every source from the unsteady rotating loading multi-source sound field. In the proposed method, the transfer relationship between
the mixed time-dependent pressure and the equivalent unsteady rotating forces is first established. Then, all the equivalent unsteady rotating forces are solved via time-domain inversion procedure. Finally, the corresponding equivalent unsteady rotating forces distributed on one interested
source are used to calculate the pressure field generated by that source alone. Numerical simulations with four unsteady point forces rotating at different speeds around two different axes examine the validity of the proposed method. Keywords: Multiple unsteady loading sources rotating at
different speeds around different axes, Sound field separation, Time-domain equivalent method
Experimental evaluation of characteristics for high-speed moving source
Authors: Akutsu Mariko , Uda Toki , Oikawa Yasuhiro
Published: December 2023

In this study, we evaluate the characteristics of a moving sound source in frequency and amplitude by visualizing a sound field around it. This is because train noise propagates with the characteristics of a moving sound source. To evaluate the characteristics, the visualization measurement
was conducted using an optical sound measurement system, parallel phase-shifting interferometer, and low-noise moving model test facility. In the frequency result, modulation was observed, and the frequencies agreed well with the theoretical values. To evaluate the amplitude of sound, we determined
the correction coefficient by which the integral pressure fluctuations recorded with the parallel phase-shifting interferometer are converted to the ones in one cross-section. By applying the conversion coefficient to the measured sound field, the shadow zone generated by the boundary layer
was observed.
Comparison of different methods for dynamic characterization of porous-elastic materials
Authors: Schweighardt Attila , Vehovszky Balázs
Published: December 2023

Acoustical simulation of porous-elastic materials requires several properties to be characterized, one of them is the dynamic mechanical behavior of the structure. For this goal, quasi-static mechanical analysis (QMA) is the generally used method executed in the ca. 20-60 Hz frequency
range, resulting constant (averaged) mechanical properties. Polymer-based materials, however, are well-known from their time- and frequency-dependent behavior. This implies the need for having frequency-dependent data in a wider frequency range, but the error induced by the fluid motion inside
the pores increases with frequency. For that reason, dynamic mechanical analysis (DMA) together with frequency-temperature superposition method was chosen to analyze the possibility of extending the evaluable frequency range. Different measurement setups and strategies were tested and evaluated
to minimize the errors coming from machine resonances and other influencing factors, and results were compared to those obtained from the classical QMA measurements. It was finally proven, that with thoroughly chosen technique, DMA can give high quality results for porous-elastic materials
as well, in a remarkably wide frequency range.
FxLMS and Lateralization: A Combined Strategy for Crosstalk Cancellation in Bone Conduction
Authors: IRWANSYAH  , OTSUKA Sho , NAKAGAWA Seiji
Published: December 2023

This study aimed to address the issue of "crosstalk" in bone conduction hearing aids, where sound meant for one ear is mistakenly perceived by the other ear via bone conduction. We explored a potential solution by canceling the crosstalk sound at the cochlea. To achieve this,
an accelerometer was placed on the mastoid to monitor the crosstalk sound produced by an audiometric bone transducer on the opposite side of the head, while a second transducer on the same side as the accelerometer was used to cancel it out. The filtered-x least mean square (FxLMS) algorithm
was used to optimize the crosstalk compensation (CTC) filter for cancellation at the mastoid. Then, the subjects manually adjusted the filter coefficients through a lateralization task to achieve crosstalk cancellation at the cochlea. This task involved modifying phase and level differences
between pure-tone sounds from the two transducers, making the sound seem to originate from the leftmost or rightmost side of the head. Our results indicated successful cancellation of crosstalk sound at the cochlea, as subjects' hearing thresholds under noise masking were lower with crosstalk
cancellation.

Strategic noise maps by means of calculation methods allow the administrations managing road infrastructures to estimate the level of noise generated during their operating regime. The sound power emitted by this source of noise depends on multiple factors, which can be classified into
three groups: meteorological conditions, variables associated with the physical characteristics of the road and variables related to road traffic. This study evaluates how temperature can have an effect on the sound pressure level generated in the surroundings of the infrastructure. A case
study is presented in this paper where on-site measurements of noise levels and temperature were performed next to a two-lane national road with mixed traffic under regular operating conditions. The results were compared with the scientific literature and those coefficients proposed in CNOSSOS-EU

Theoretical and numerical analysis on low-frequency sound transmission from façades into room
Authors: Liu Jinyu , Inoue Naohisa , Sakuma Tetsuya
Published: December 2023

Regarding low-frequency sound transmission from building façades into room for outdoor noise, its mechanism is very complicated due to the combination of outer walls and windows, the vibration behavior of an entire building structure, and the acoustic coupling with an interior
sound field. In particular, the installation of a double window system involves combined phenomena of its resonance transmission and normal modes of the room, which has not been fully understood. In order to investigate the phenomena, a theoretical examination is first conducted based on a
one-dimension vibro-acoustic model assuming piston vibration of double windowpanes and air spring between them. Next, numerical simulations based on the vibro-acoustic FEM are performed for a house model that consists of outer walls and double windowpanes. The results are compared to clarify
the effects of the thickness, stiffness and size of glazing and the air layer thickness for the double window, and also sound absorption of the room. Furthermore, the composite soundproofing effect of weight increasing of the outer walls and installation of the double window is examined to
consider appropriate measures for low-frequency sound.

Published: December 2023

Noise control for vehicle mainly uses a reduction method through sound absorbing and insulating materials but has disadvantages of increasing cost and weight. It is known that the noise reduction performance of Active Noise Control (ANC) technology that can be considered as an alternative
is limited to the low frequency range. However, there could be a case when the use of active noise cancellation is required at higher frequency range. Therefore, the purpose of this paper is to find out how much high-frequency noise can be controlled by applying active noise cancellation and
the performance of ANC according to the equipment used. For this end, an ANC experimental environment was installed at the passenger's seat interior vehicle. By using Filtered-x Least Mean Square (FxLMS) algorithm based on adaptive control, ANC was conducted to reduce the high frequency noise
in the 2kHz~4kHz and its noise reduction performance was compared according to the following variables: Filter length, step size, sampling frequency, etc. As a result of selecting the audio DSP board as the control system and applying appropriate filter length, step size, and sampling frequency,
noise reduction of up to 40 dB(A) was obtained at the position of both ears of the occupant.

The physical phenomenon of sound can be visualized with a high degree of freedom in terms of sound pressure level and loudness with respect to time and frequency. On the other hand, to obtain a sensory evaluation of the sound, it is a labor-intensive and costly task to prepare a certain
number of subjects, set up a playback environment and playback equipment, tabulate the results, and perform subsequent analysis. The system introduced here can easily create simple listening experiments using sound source data managed on the cloud, and distribute the experiments on the Web.
Subjects can participate in experiments without time and travel constraints, and experiments with an unprecedented number of subjects can be performed in a short period of time. In addition, the correlation between the rating scale and the physical quantity is automatically calculated, reducing
the man-hours required for analysis. In this paper, we present the advantages and disadvantages of this system over conventional controlled subjective evaluation experiments, and mention the value of using this system based on actual examples.

Introdução: A impactação dentária é uma condição em que os dentes não erupcionam normalmente na cavidade oral por algum impedimento mecânico. Após os terceiros molares, os caninos são os dentes mais propensos à impactação, sendo mais comum em mulheres do que em homens, tendo maior acometimento do canino superior em relação ao inferior. A impactação dentária dos caninos pode ocorrer uni ou bilateralmente, com uma maior proporção de casos unilaterais. O diagnóstico de impactação dentária é feito por meio de anamnese, exames clínicos e radiográficos. O tratamento depende da posição do canino em relação aos dentes adjacentes e sua distância da linha de oclusão, podendo incluir abordagens conservadoras, cirúrgicas ou orto-cirúrgicas. Relato de Caso: Paciente do sexo feminino de 46 anos, com histórico de caninos superiores inclusos e impactados. Devido à idade da paciente e a posição dos dentes, optou-se por realizar a exodontia dos caninos. A cirurgia foi realizada sob anestesia local e, após a sutura, confeccionada uma contenção para garantir a estabilidade dos dentes e fixação de provisório. Discussão: Fatores sistêmicos e locais, como problemas genéticos, deficiências endócrinas, dentes supranumerários e falta de espaço na arcada dentária podem estar associados à impactação de caninos permanentes. A remoção cirúrgica foi necessária devido às complicações relacionadas à impactação de caninos. Conclusão: O tratamento dos caninos inclusos deve levar em conta a possibilidade de reposicioná-los no arco. Em casos nos quais esta manobra se torne inviável, a exodontia é a manobra terapêutica de eleição.

Os cuidados paliativos (CP) consistem na assistência promovida ao paciente e aos seus familiares objetivando a melhoria na qualidade de vida no contexto de doenças ameaçadoras à vida, por meio de identificação, prevenção e alívio da dor e do sofrimento. É um tema cada vez mais abordado no meio médico, devido ao aumento da expectativa de vida populacional e ao aumento da prevalência de doenças crônicas. No entanto, é notório o déficit de conhecimento teórico e prático sobre o assunto, uma vez que são minoria as escolas de medicina que tem os CP em suas grades curriculares, o que leva a formação de médicos despreparados para atuarem em situações tão especiais como as que os demandam. O presente estudo é uma revisão integrativa da literatura que busca revisar e demonstrar a realidade do ensino médico brasileiro sobre este tema tão importante. O levantamento bibliográfico foi feito através das plataformas: Scielo, Biblioteca Virtual de Saúde e PubMed, foram analisados e discutidos 11 artigos na íntegra. Conclui-se que, a maioria das escolas de medicina do Brasil não abordam os CP na formação de seus profissionais ou não os abordam de forma prática para a atuação. Apesar disso, a crescente discussão sobre o assunto teve impactos positivos, determinando a inclusão do tema nas Diretrizes Nacionais Curriculares dos cursos de Medicina, visando uma mudança no atual panorama apresentando neste trabalho.

Na atualidade, foi crescente o aumento de cirurgias plásticas no Brasil, as principais causas são a melhora da autoestima das pacientes. No entanto, nem sempre as próteses de silicone ficam com as pacientes, pois, após cirurgias algumas pacientes possuem complicações como, por exemplo, inflamações nas articulações e dores crônicas, conhecida como a inflamação por ASIA (Síndrome Autoimune-inflamatória Induzida por Adjuvantes) e outras doenças que são consideradas autoimunes e com dificuldade de diagnóstico. O presente trabalho foi realizado por meio de uma revisão sistemática da literatura, que possui como objetivo sintetizar as informações que existe disponível na literatura sobre a relação complexa de complicações e as próteses de silicone. Existe uma relação entre a inflamação ASIA e as prótese de silicone, uma vez que as próteses liberam o princípio ativo que agravam a inflamação. Porém, não são todas as pacientes que apresentam tal enfermidade. O explante de silicone nas pacientes que apresentam algum tipo inflamação pode ser uma das soluções para melhorar a qualidade de vida das pacientes.

Published: December 2023

A pelve constitui uma peça importante para manutenção da postura bípede, sendo também importante na abordagem osteopática. As alterações sacroilíacas acarretam disfunções mecânicas não só na cintura pélvica, como também no joelho, já que músculos biarticulares estarão modificando a fisiologia articular dessas mesmas estruturas. Sendo assim, os excessos de jogos e treinamentos levam os jogadores a uma maior predisposição às lesões. Verificar a prevalência de lesões osteopáticas da articulação sacroilíaca dos jogadores de futebol com relação a perna dominante e não-dominante do chute. O estudo foi composto de 20 jogadores com idade entre 16 e 18 anos. Foram avaliadas as articulações sacroilíacas através dos testes de Gillet de flexão em pé (TFP) e de flexão sentado (TFS) antes do treinamento. Quando encontrada alguma lesão osteopática, o fisioterapeuta normalizou articulação através de técnicas osteopáticas, sendo os jogadores reavaliados após o treinamento. A idade média dos participantes foi de 17,2 ± 0,77 anos, com relação a lesão osteopática da articulação sacroilíaca, 15(75%) jogadores apresentaram a lesão e 5 (15%) não tinham lesão.

A obesidade atua como fator inflamatório importante no organismo humano, atuando e alterando significativamente a homeostase do indivíduo. Nesse contexto, a introdução da cirurgia bariátrica como prática terapêutica no controle de peso corporal tem se destacado como uma abordagem eficaz no tratamento da obesidade e suas comorbidades, incluindo diabetes mellitus tipo 2 (DM2) e hipertensão arterial sistêmica (HAS). Nesta revisão da literatura, exploramos estudos que investigam os efeitos da cirurgia bariátrica na redução do DM2 e da HAS, bem como os mecanismos subjacentes a essas melhorias. As buscas foram realizadas nas bases de dados PubMed, Scopus e Web of Science, utilizando termos de pesquisa relacionados à “cirurgia bariátrica”, “diabetes” e “hipertensão arterial sistêmica”. Dentre os estudos selecionados houve a constatação de uma sinalização benéfica do uso da cirurgia bariátrica no controle da obesidade e também na melhoria dos padrões pressóricos e também de redução da resistência insulínica. Conclui-se que a cirurgia bariátrica tem seu espaço no arsenal terapêutico de controle às patologias citadas, mas que sua indicação deve ser criteriosa e associada a melhora de hábitos de vida.

Severe hyperglycemia leads to classic symptoms such as polyuria, polydipsia, fatigue, and decreased performance. This condition presents, different classifications considering its possible etiologies, being four subtypes: type 1, type 2, gestational and other specific forms of diabetes type 3c. It is suggested that there is a strong association between diabetes mellitus (especially type 2 diabetes mellitus) and carcinogenesis, but this correlation is still underestimated during the diagnosis of diabetes. This paper aims to review the literature on the PubMed search platform for papers from the last five years on the correlation between pancreatic cancer and diabetes; through the adoption of specific descriptors and rigorous selection criteria of the selected articles to be used as a basis, and thus a total of twenty two articles fit to carry out this work. Based on the current literature, several studies have suggested that diabetes mellitus and cancer are often coexisting diseases, but they are rarely diagnosed concurrently and consequently make treatment difficult and the prognosis tends to be unfavorable, which makes greater disclosure about the correlation essential. among such diseases, aiming at a better diagnosis in a systematic way, and thus making the patient's prognosis more reliable.

Pressupondo que as puérperas possuem pouco conhecimento sobre violência obstétrica as quais são amiúde submetidas, que essa ultrapassa o corpo físico, acometendo a saúde mental e, que as vítimas não a reconhecem quando a estão sofrendo, devido às emoções do processo. O trabalho de parto é uma ocasião importante na vida da mulher. Um momento que deve ser cercado de rede de apoio que promova o acolhimento e segurança da puérpera. Infelizmente, não é isso que se observa na rotina de atendimento hospitalar, nomeadamente no sistema único de saúde (SUS), quando não é incomum presenciar passagens desestimulantes e, até mesmo cruéis como as asseverações propaladas por profissionais da saúde à parturientes em momento de sofrimento.  Avaliar a percepção das puérperas acerca da violência obstétrica no parto, e seus direitos. Trata-se de uma Revisão Narrativa de literatura em estudos científicos sobre percepção das puérperas relacionada a violência obstétrica. Da pesquisa que foi realizada nas bases de dados Brazilian Journal of Health Review, PubMed, BVS saúde e SciELO foram selecionados 4 estudos com relatos de vivências durante o procedimento de parto. mostraram, além da parcimoniosa quantidade de pesquisa sobre o tema, a carência de humanização de profissionais em relação ao tratamento dispensado à paciente e, deficiência de conhecimento, por parte das pacientes, em relação aos seus direitos. A pesquisa revelou que, além do número limitado de estudos sobre o tema, havia falta de humanidade no tratamento prestado aos pacientes pelos profissionais e falta de conhecimento por parte dos pacientes sobre seus direitos.
