Notas sobre o pesquisar em cena(s) / Notes on researching in scenes / Notas sobre la investigación en escena(s)

O presente artigo tem como objetivo apresentar a construção metodológica desenvolvida em uma pesquisa de mestrado, na qual sustentamos a escrita de cenas como método de pesquisa da escuta clínica. As cenas do trabalho em questão foram recolhidas ao longo do tempo, no contorno da experiência de um projeto de extensão universitária de atenção à infância e adolescência em situação de vulnerabilidade social, situado em uma comunidade periférica. Apresentamos, neste texto, as interrogações que se elaboraram em torno da escolha pelo trabalho com cenas, e compartilhamos o resgate histórico dessas como um método de escrever a clínica, bem como a retomada de sua análise a partir da tradição psicanalítica. Amparadas nesta teoria e em leituras e contribuições do filósofo francês Jacques Derrida, embasamos a noção de que a cena se constitui como um lugar de produção, ao engendrar a configuração particular de elementos significantes nos processos de subjetivação e de construção social. A cena não é, então, compreendida aqui como uma representação do que acontece na clínica, mas como um modo de produzir a escuta e os seus processos de investigação.(AU)

This article aims to present the methodological construction developed in a master's research, in which the writing of scenes as a method of clinical listening research was endorsed. The scenes from the study in question were collected over time, from the experience gained in a project conducted within a university extension program on care in childhood and adolescence in social vulnerability, in a peripheral community. In this study, we present some questions that were elaborated surrounding the choices of working with scenes; and we share the historical rescue of this work as a method of writing on clinic practices and resuming their analysis from the psychoanalytic tradition. Based on the psychoanalytic theory and on the readings and contributions of the French philosopher Jacques Derrida, we corroborate the notion that the scene is constituted as a place of production, engendering the particular configuration of significant elements in the processes of subjectivation and social construction. Here, the scene is not a representation of clinical practice but one mode of producing listening and its research processes.(AU)

Organic Photo-antimicrobials: Principles, Molecule Design, and Applications.

The emergence of multi-drug-resistant pathogens threatens the healthcare systems world-wide. Recent advances in phototherapy (PT) approaches mediated by photo-antimicrobials (PAMs) provide new opportunities for the current serious antibiotic resistance. During the PT treatment, reactive oxygen species or heat produced by PAMs would react with the cell membrane, consequently leaking cytoplasm components and effectively eradicating different pathogens like bacteria, fungi, viruses, and even parasites. This Perspective will concentrate on the development of different organic photo-antimicrobials (OPAMs) and their application as practical therapeutic agents into therapy for local infections, wound dressings, and removal of biofilms from medical devices. We also discuss how to design highly efficient OPAMs by modifying the chemical structure or conjugating with a targeting component. Moreover, this Perspective provides a discussion of the general challenges and direction for OPAMs and what further needs to be done. It is hoped that through this overview, OPAMs can prosper and will be more widely used for microbial infections in the future, especially at a time when the global COVID-19 epidemic is getting more serious.

A novel intraoral neuromuscular stimulation device for treating sleep-disordered breathing.

PURPOSE: To ascertain the usefulness of a novel intraoral neuromuscular stimulation device in treating patients with primary snoring and mild obstructive sleep apnoea (OSA). This device uses daytime awake neuromuscular electrical stimulation (NMES) as an application to induce toning of the tongue muscles. METHODS: A prospective cohort study of 70 patients with sleep-disordered breathing was conducted. Objective snoring and respiratory parameters were recorded with 2 consecutive night WatchPat sleep studies before and after treatment. The device was used for 20 min once daily for a 6-week period. Secondary outcome measures using visual analogue scale reporting of snoring by patient and Epworth Sleepiness Score (ESS) were recorded. Quality of life parameters were also noted. RESULTS: Objective reduction of snoring was noted on the sleep studies in 95% of participants, with an average snoring time reduction of 48%. Subjectively, the visual analogue scale reported by partners' similarly demonstrated reduction in 95% of the patients with an average reduction of 40%. In a subset of 38 patients with mild OSA, AHI reduced from 9.8 to 4.7/h (52% reduction), ODI 7.8 to 4.3/h (45% reduction), and ESS from 9.0 to 5.1. Adverse effects encountered were minimal. CONCLUSION: This prospective cohort study demonstrates a notable improvement in both objective and subjective parameters of snoring and mild OSA in both simple snorers and patients with mild OSA. This device offers a safe and novel approach to reduce snoring and mild OSA by utilising intraoral neuromuscular electrical stimulation. This could be a preferred option for patients as it alleviates the need of using an oral device during sleep. TRIAL REGISTRATION: clinicaltrials.gov identifier NCT03829956.

Diagnóstico de la dinámica cardiaca mediante proporciones de la entropía / Heart dynamics diagnosis based on entropy proportions

Introducción: Los valores de la frecuencia cardiaca normales y anormales registrados en los equipos electrocardiográficos ambulatorios o continuos han sido caracterizados mediante nuevas metodologías diagnósticas, las cuales se han desarrollado en el contexto de la teoría de los sistemas dinámicos y la entropía. Objetivo: Evaluar la dinámica cardiaca de adultos, teniendo en cuenta su comportamiento en el contexto de la teoría de sistemas dinámicos y las proporciones de la entropía mediante un estudio ciego. Métodos: Se realizó una prueba diagnóstica mediante un estudio ciego de 500 Holter, aplicando una nueva metodología basada en las proporciones de la entropía del atractor numérico construido con los valores registrados en el Holter. Para esto, los valores máximos y mínimos de la frecuencia cardiaca para cada hora, así como el número de latidos, fueron tomados de cada Holter durante, mínimo, 18 horas. Con estos valores se generó un atractor numérico que cuantificó la probabilidad de parejas de frecuencias cardiacas consecutivas. Se evaluó cada dinámica a partir de los valores de entropía y de sus proporciones. Posteriormente, estos resultados fueron comparados con la evaluación clínica convencional estimando la sensibilidad y especificidad, así como el coeficiente Kappa. Resultados: Se encontraron diferencias entre la dinámica de casos normales y anormales, en las dinámicas cardiacas evaluadas en 18 horas, hallando valores de sensibilidad y especificidad del 100 por ciento y coeficiente Kappa de uno, respecto al diagnóstico clínico convencional. Conclusiones: Los valores de entropía y de sus proporciones permiten diferenciar cuantitativamente la normalidad de la enfermedad en la dinámica cardiaca, durante un mínimo de 18 horas(AU)

Introduction: The normal and abnormal heart rate values recorded on ambulatory or continuous electrocardiographic devices have been characterized with novel diagnostic methodologies developed in the context of dynamic systems and entropy theory. Objective: Through a blind study, evaluate the heart dynamics of adults taking into account their behavior in the context of dynamic systems theory and entropy proportions. Methods: A diagnostic test was conducted through a 500 Holter blind study, applying a novel methodology based on the entropy proportions of the numerical attractor constructed with the values registered on the Holter device. To achieve this end, maximum and minimum heart rate values for each hour, as well as the number of beats, were obtained from each Holter device for at least 18 hours. Based on these values, a numerical attractor was generated which quantified the probability of consecutive heart rate pairs. Each dynamic was evaluated in terms of entropy values and their proportions. These results were then compared with the conventional clinical evaluation, estimating the sensitivity and specificity as well as the kappa coefficient. Results: Differences were found between the dynamics of normal and abnormal cases, in the heart dynamics evaluated in 18 hours, finding sensitivity and specificity values of 100 percent and a kappa coefficient of 1, with respect to conventional clinical diagnosis. Conclusions: Entropy values and their proportions make it possible to quantitatively differentiate the normality of the disease in heart dynamics for a minimum of 18 hours(AU)

Propuesta de sistema innovador de comunicación digital utilizando IoT para equipo biomédico de monitoreo de pacientes: de interés sector salud pública / Innovative digital communication system proposal using IoT in biomedical equipment for patient monitoring: interest in public health sector

La presente propuesta de diseño busca la interoperabilidad de datos en salud por medio de la integración de un sistema de comunicación a equipos especializados, utilizando las TI (Tecnologías de la Información) y el IoT (Internet de las Cosas) en los equipos biomédicos especializados o monitor que está siendo utilizado actualmente en los centros hospitalarios público a nivel nacional para la medición de signos vitales, con el objetivo de poder brindar una atención sanitaria a pacientes con padecimientos médicos y que necesitan de una constante supervisión y vigilancia. En los centros hospitalarios se cuenta con equipo biomédico especializado que carece de dichas funcionalidades. Esto repercute u obliga al responsable especialista a tener que estar frente al monitor y paciente para poder observar las mediciones o lecturas que presenta un paciente.

This design proposal seeks the interoperability of health data through the integration of a communication system to specialized equipment, using IT (Information Technology) and IoT (Internet of Things) in specialized biomedical equipment or monitor that is currently being used in public hospitals nationwide for the measurement of vital signs, in order to provide health care to patients with medical conditions and who need constant surveillance. Hospitals have specialized biomedical equipment that lacks these functionalities. This forces the responsible specialist to have to be in front of the monitor and the patient to be able to observe the measurements or readings that a patient presents.

Protective and regenerative effects of a novel medical device against esophageal mucosal damage using in vitro and ex vivo models.

Gastroesophageal reflux disease (GERD) is a common digestive disorder that causes esophagitis and injuries to the esophageal mucosa. GERD symptoms are recurrent during pregnancy and their treatment is focused on lifestyle changes and nonprescription medicines. The aim of this study was to characterize the mechanism of action of a new patented medical device, an oral formulation containing hyaluronic acid, rice extract, and amino acids dispersed in a bioadhesive polymer matrix, by assessing its protective effects in in vitro and ex vivo models of esophageal mucosa damage. Acidic bile salts and pepsin cocktail (BSC) added to CP-A and COLO-680 N esophagus cells were used as an in vitro GERD model to evaluate the binding capacities, anti-inflammatory effects and reparative properties of the investigational product (IP) in comparison to a viscous control. Our results showed that the IP prevents cell permeability and tight junction dysfunction induced by BSC. Furthermore, the IP was also able to down-regulate IL-6 and IL-8 mRNA expression induced by BSC stimulation and to promote tissue repair and wound healing. The results were confirmed by ex vivo experiments in excised rat esophagi through the quantification of Evans Blue permeability assay. These experiments provided evidence that the IP is able to bind to the human esophagus cells, preventing the damage caused by gastroesophageal reflux, showing potential anti-irritative, soothing, and reparative properties.

Anestesia en el angiofibroma juvenil: un reto al anestesiólogo / Anesthesia in juvenile angiofibroma: an challenge for the anesthesiologist

Introducción: La anestesia para el angiofibroma juvenil es una de las intervenciones más complejas dentro de la otorrinolaringología, pues el sangramiento incoercible causa hipovolemia aguda la cual se produce en un breve período y lleva al shock hipovolémico y a la muerte de no tratarse adecuadamente. Objetivo: Realizar una actualización sobre el perioperatorio de la anestesia en el angiofibroma juvenil. Desarrollo: Se debe minimizar las pérdidas sanguíneas a toda costa. La mejor asociación fue la hipotensión inducida, la hemodilución hipovolémica y el predepósito de sangre autóloga, con la angiografia y embolización arterial selectiva del tumor. Conclusiones: La exéresis quirúrgica del angiofibroma juvenil es una intervención de alto riesgo. El equipo de trabajo constituye un elemento primordial. La asociación de hipotensión inducida, hemodilución hipovolémica y predepósito de sangre autóloga son los pilares fundamentales para la mejor evolución de estos pacientes(AU)

Objective: To carry out an update about the perioperative period of anesthesia in juvenile angiofibroma. Development: Blood losses must be minimized at all costs. The best association was induced hypotension, hypovolemic hemodilution, and autologous blood predeposit, with angiography and selective arterial embolization of the tumor. Conclusions: Surgical removal of juvenile angiofibroma is a high-risk intervention. The work team is an essential element. The association of induced hypotension, hypovolemic hemodilution, and autologous blood predeposit are the fundamental pillars for the best evolution of these patients(AU)

'Being a midwife is being prepared to help women in very difficult conditions': midwives' experiences of working in the rural and fragile settings of Ituri Province, Democratic Republic of Congo.

INTRODUCTION: Maternal and neonatal health are core focus areas in fragile and conflict-affected areas, and hence midwives are key actors. But there is currently very little evidence on midwives' experiences, the challenges that they face and coping strategies they employ in the challenging and fragile rural areas of Ituri Province in the north-eastern part of the Democratic Republic of Congo (DRC). This understanding is critical to developing strategies to attract, retain and support midwives to provide vital services to women and their families. This study aims to explore midwives' work experiences and challenges through time from initial professional choice to future career aspiration in rural Ituri Province, north-eastern DRC. METHODS: As part of a qualitative approach, life history interviews with 26 midwives and 6 ex-midwives, and three focus group discussions with 22 midwives in three health districts of Ituri Province (Bunia, Aru and Adja), were conducted in 2017. Purposive sampling was used to recruit research participants. The transcripts were digitally recorded, and thematically analyzed using NVivo software. A timeline framework was deployed in the analytical process. RESULTS: Problem solving, childhood aspirations and role models were the main reasons for both midwives and ex-midwives to join midwifery. Midwives followed a range of midwifery training courses, resulting in different levels and training experiences. Midwives faced many work challenges: serious shortages of qualified health workers; poor working conditions due to lack of equipment, supplies and professional support; and no salary from the government. This situation was worsened by insecurity caused by militia operating in some rural health districts. Midwives in those settings have developed coping strategies such as generating income and food from farm work, lobbying local organizations for supplies and training traditional birth attendants to work in facilities. Despite these conditions, most midwives wanted to continue working as midwives or follow further midwifery studies. Family-related reasons were the main reasons for most ex-midwives to leave the profession. CONCLUSION: Midwives play a critical role in supporting women to deliver babies safely in rural Ituri Province. They face immense challenges and demonstrate bravery and resilience as they navigate the interface between underresourced health systems and poor, marginalized rural communities. This situation requires a call to action: donors need to prioritize these contexts; and the government and other stakeholders in DRC need to invest more in improving security conditions as well as working conditions and professional support for midwives in rural Ituri Province. Only then will midwives be able to provide the critical services that women and their families need, and therefore contribute to achieving universal health coverage.

Resource evaluation framework for total knee arthroplasty.

PURPOSE: This article describes a framework for evaluating efficiency of OR procedures incorporating time measurement, personnel activity, and resource utilization using traditional industrial engineering tools of time study and work sampling. METHODS: The framework measures time using time studies of OR procedures and work sampling of personnel activities, ultimately classified as value-added or non-value-added. Statistical methods ensure that the collected samples meet adequate levels of confidence and accuracy. Resource utilization is captured through documentation of instrument trays used, defects in instruments, and trash weight and classification at the conclusion of surgeries. FINDINGS: A case study comprising 12 observations of total knee arthroplasty surgeries illustrates the use of the framework. The framework allows researchers to compare time, personnel, and resource utilization simultaneously within the OR setting. PRACTICAL IMPLICATIONS: The framework provides a holistic evaluation of methods, instrumentation and resources, and staffing levels and allows researchers to identify areas for efficiency improvement. ORIGINALITY/VALUE: The methods presented in this article are rooted in traditional industrial engineering work measurement methods but are applied to a healthcare setting in order to efficiently identify areas for improvement including time, personnel, and processes in operating rooms.

Provision of Care to Preterm Infants at Resource Limited Health Facilities of Mopani District, South Africa.

Background: Inadequate neonatal facilities in rural areas is one of the challenges affecting the management of preterm infants. In low income countries with limited resources, over 90% of preterm babies die within few days of life. Purpose: The purpose of this study was to describe the challenges encountered by midwives when providing care to preterm infants at resource limited health facilities in Limpopo Province, South Africa. Methods: Qualitative research approach, using exploratory and descriptive design was used. Non-probability purposive sampling was used to select twenty three midwives who had an experience of two or more years in maternity. Data was collected using unstructured individual interviews, which were voice recorded and transcribed and data analysed qualitatively through the open-coding method. Findings: Revealed one theme, preterm condition and expected care; with sub-themes namely; perceived causes of preterm complications and deaths, preterm babies experience several difficulties which need specialised care, the need for constant individualised care and monitoring of preterm infants by midwives, functional relevant equipment needed for care of preterm infants, a need for constant training for midwives regarding care of preterm infants, and importance for a proper structure to house preterm infants which will lead to quality care provision. Conclusion: Preterm babies need simple essential care such as warmth, feeding support, safe oxygen use and prevention of infection. Lack of adequate resources and limited skills from midwives could contribute to morbidity and mortality. Health facility managers need to create opportunities for basic and advanced preterm care to equip the skills of midwives by sending them to special trainings such as Limpopo Initiative Neonatal Care (LINC), Helping Baby Breath (HHB) and Neonatal Intensive Care Unit (NICU). Operational managers should be involved in the identification, procurement and supply of required equipment. Continuous health education should be provided on the mothers about kangaroo mother care (KMC) and measures to prevent infections in the neonatal unit.

Regulatory perspectives on next-generation sequencing and complementary diagnostics in Japan.

INTRODUCTION: The 'one biomarker/one drug' scenario is unsustainable because cancer is a complex disorder that involves a number of molecular defects. In the past decade, major technological advances have lowered the overall cost and increased the efficiency of next-generation sequencing (NGS). AREAS COVERED: We review recent regulations on NGS and complementary diagnostics in Japan, mainly focusing on high-quality studies that utilized these new diagnostic modalities and were published within the last 5 years. We highlight significant changes in regulation, and explain the direction of efforts to translate the results of NGS and complementary diagnostics into clinical practice. EXPERT OPINION: NGS holds a number of advantages over conventional companion and complementary diagnostics that enable simultaneous analyzes of multiple cancer genes to detect actionable mutations. Parallel technological developments and regulatory changes have led to the rapid adoption of NGS into clinical practice. NGS-based genomic data have been leveraged to better understand the characteristics of a disease that affects its patient's response to a given therapy. As NGS-based tests become more widespread, however, Japanese authorities will face significant challenges particularly with respect to the complexity of genomic data, which will have to be managed if NGS is to benefit patients.

Evaluation of soft-tissue response around laser microgrooved titanium percutaneous devices.

Percutaneous devices are prone to epidermal downgrowth and sinus tract formation, which can serve as a nidus for bacterial colonization and increase the risk of peri-prosthetic infection. A laser microgrooved topography has been shown to limit gingival epidermal downgrowth around dental implants. However, the efficacy of this laser microgrooved topography to limit epidermal downgrowth around nongingival percutaneous devices is yet to be investigated. In this study, devices with a porous-coated subdermal component and a percutaneous post were designed and manufactured. The proximal 2 mm section of the percutaneous post were left smooth, or were textured with either a porous coating, or with the laser microgrooved topography. The smooth and porous topographies served as controls. The devices were tested in a hairless guinea pig back model, where 18 animals were randomly assigned into three groups, with each group receiving one implant type (n = 6/group). Four weeks postimplantation, the devices with surrounding soft-tissues were harvested and processed for histological analyses. Results indicated that the laser microgrooved topography failed to prevent epidermal downgrowth (23 ± 4%) around percutaneous posts in this model. Furthermore, no significant differences (p = 0.70) in epidermal downgrowth were present between the three topographies, with all the groups exhibiting similar measures of downgrowth. Overall, these findings suggest that the laser microgrooved topography may not halt downgrowth around percutaneous devices for dermal applications.

Study on the effect of phototherapy for inhibition of symptoms associated with allergic rhinitis.

Summary: Previous published work has indicated that treatment of the inside of the nose with certain wavelengths of light can reduce the symptoms of allergic rhinitis. The objective of the study was to compare the efficacy of the phototherapy device on the relief of a range of symptoms provoked by indoor and outdoor allergens. A phototherapy emits visible light (mUV/VIS) and infrared light, and was compared to a placebo device which did not emit light on two groups of allergic rhinitis sufferers. Rhinophototherapy improved nasal symptoms of allergic rhinitis arising from exposure to indoor and outdoor allergens. The difference in the intensity of symptoms scored at the baseline, and at the final visit for the group using the photoperiod device was significantly lower. The device could potentially help improve the quality of life for allergy sufferers. Phototherapy may be suitable for sufferers either as a replacement therapy or used alongside traditional medication.

Extract of Mangifera indica L. leaves may reduce biofilms of Staphylococcus spp. in stainless steel and teatcup rubbers.

Human ingestion of antimicrobial residues in dairy products is a problem of public health. In this study we evaluated antibacterial effectiveness of aqueous and ethanolic leaf extracts of Mangifera indica L. as a natural alternative for reduction of Staphylococcus spp. biofilms. Eight Staphylococcus spp. strains from cows with mastitis and the Staphylococcus aureus strain (ATCC 25923) were evaluated. High performance liquid chromatography indicated the presence of phenolic compounds in the aqueous extract. Agilent Technologies gas chromatography revealed the presence of phenolic compounds, carbohydrates, and gallic acid in ethanolic extract. The tannin contents were 2.27 ± 0.01 and 2.67 ± 0.01% for ethanolic extract and aqueous extract, respectively. Extracts were evaluated in agar diffusion test and the size of inhibition zones were compared. The ethanolic extract was the most effective, showing minimum inhibitory concentrations and minimum bactericidal concentrations between 1.8-7.5 and 15.1-45.3 mg/ml, respectively. After tannin removal, the extracts were less effective, indicating these secondary metabolites as one of the main antibacterial compounds. The ethanolic extract at 45.3 mg/ml reduced mature biofilms in teat rubber (average: 3.91 log reduction) and stainless steel (average: 3.87 log reduction) after 5 min of contact. The extracts of M. indica leaves represent natural alternatives against Staphylococcus spp. strains and the ethanolic extract shows potential as a natural sanitizer.

[Health technology assessment of innovative medical devices: Timing and decision at national and local level]. / Accès au marché des dispositifs médicaux innovants : articulation entre évaluations nationales et hospitalières.

INTRODUCTION: The Medical Device Committee (CODIMS) evaluates all innovative medical devices (MD) before their introduction in the hospitals of the Assistance publique-hôpitaux de Paris (AP-HP). At the national level, the Medical Device and Health Technology Evaluation Committee (CNEDiMTS) provides recommendation for MD with respects to reimbursement by the National Health Insurance Fund. The aim of this study is to compare the recommendations of both committees and to analyze their timing on a six-year period. MATERIAL AND METHOD: We selected all innovative MD assessed by the CODIMS between 2013 and 2018. We retrieved all the recommendations for these MD from the CNEDiMTS. We performed quantitative and qualitative analysis of data collected. RESULTS: On 30 innovative MD assessed by both the CODIMS and the CNEDiMTS, 11 (37%) evaluations were performed by the CODIMS before the CNEDiMTS evaluation. They occurred approximately a year before the CNEDiMTS recommendation (an average of 378 days). Among the 25 MD with a recommendation of both committees, the two opinions were consistent in 88 per cent of all cases. DISCUSSION/CONCLUSION: This study highlights that there is a good consistency between the recommendations of both committees. This suggests that the MD evaluations conducted at the hospital level are relevant and timely. Finally, a better coordination between the national and local levels should be promoted for the MD assessment.
