Authors: Sousa de Morais Carvalho Filho Filho Rothchild , Celestino Júnior Onesio , Alves Élida Maria Amaral , Alves Silvana De Brito 
Published: April 2024

Os indicadores naturais ácido-base são corantes extraídos de plantas. Esses corantes são ricos em antocianinas, substância responsável pela variação de coloração em função do pH. As antocianinas são pertencentes ao grupo dos flavonóides fenólicos. Esta substância compõem o maior grupo de pigmentos solúveis em meio aquoso do reino vegetal e são encontrado em maior quantidade nos grupos das angiospermas. De modo geral, a estabilidade dos extratos naturais depende de dois fatores: temperatura e tempo de armazenamento. Neste contexto, o presente trabalho avaliou a estabilidade térmica do extrato da allamanda (Allamanda cathartica L.) e do cróton (Codiaeum variegatum (L.) A. Juss), em temperatura de 0 °C e 25 °C, no período de 5, 10 e 30 dias. Observou-se que os extratos 1 e 2 (allamanda e cróton) apresentaram excelente estabilidade térmica. Os extratos foram enumerados da seguinte forma: extrato 1 (alamanda), extrato 2 (cróton), extrato 3 (beterraba) e extrato 4 (repolho roxo). Os extratos 1 e 2 (alamanda-amarela e louro variegado) apresentaram uma estabilidade térmica significativa em diferentes temperaturas ao longo do período de 30 dias em comparação com os já presentes na literatura, sendo uma alternativa de fácil aquisição e baixo custo para serem usados no ensino de química.

ABSTRACT
ATTR amyloidosis involving the heart solely despite it being a multisystem disease is quite an enigmatic entity. Here is a case of a 65-year-old man presenting with features of heart failure with reduced ejection fraction who on extensive workup and imaging was found to have cardiac amyloidosis of ATTR hereditary variety despite a negative family history. This sporadic case of hereditary transthyretin amyloidosis affecting only the heart was put through profound genetic workup and eventually treated with newer but expensive drugs in the hopes to achieve clinical remission.

Published: April 2024

Background An easy-to-use application to facilitate direct observation and allow for 2-way feedback between residents and faculty is needed.
Objective To develop a mobile-based application (app) with the goals of (1) providing just-in-time feedback to residents; (2) improving timeliness of feedback by faculty; and (3) allowing residents to comment on the value of faculty feedback.
Methods Fifty-one of 69 (74%) internal medicine (IM) residents and 20 of 25 (80%) IM core faculty participated in the study from July 1, 2020, to December 31, 2021. An iOS app was designed by authors with expertise in medical education and application development to capture entrustable professional activities (EPAs)-based feedback (eg, informed consent) based on direct observation of residents’ skills in the workplace. App utilization and narrative feedback characteristics of faculty comments were examined by exporting the data from the database server. The end user satisfaction was examined using a survey instrument.
Results Eighty-seven percent of assessments (117 of 134) initiated were fully completed by residents and faculty. Faculty narrative comments were noted in 97% (114 of 117) of completed assessments and 64% (75 of 117) of residents’ feedback to the faculty contained narrative comments. Eighty-three percent (97 of 117) of comments were behaviorally specific and 71% (83 of 117) contained an actionable item. Eighty-six percent (18 of 21) of residents and 90% (9 of 10) of core faculty stated that this application promoted an educational interaction between them.
Conclusions This app facilitates the efficient completion of EPA-based formative assessments and captures bidirectional feedback in the workplace setting.

Background Residents report high levels of distress but low utilization of mental health services. Prior research has shown several barriers that prevent residents from opting into available mental health services.Objective To determine the impact of a mental health initiative centered around an opt-out versus an opt-in approach to help-seeking, on the use of psychotherapy.Methods Resident use of psychotherapy was compared between 2 time frames. During the first time frame (July 1, 2020 to January 31, 2021), residents were offered access to therapy that they could self-initiate by calling to schedule an appointment (opt-in). The second time frame (February 1, 2021 to April 30, 2021) involved the switch to an opt-out structure, during which the same residents were scheduled for a session but could choose to cancel. Additional changes were implemented to reduce stigma and minimize barriers. The outcome was psychotherapy use by residents.Results Of the 114 residents, 7 (6%) self-initiated therapy during the opt-in period. When these same residents were placed in an opt-out context, 59 of the remaining 107 residents (55%) kept their initial appointment, and 23 (39%) self-initiated additional sessions. Altogether, across both phases, a total of 30 of the 114 residents initiated therapy (ie, 7 during the opt-in and 23 during the opt-out). The differences in therapy use between the 2 phases are statistically significant (P&lt;.001 by McNemar’s test).Conclusions There was a substantial increase in residents’ use of psychotherapy after the opt-out initiative that included efforts to reduce stigma and encourage mental health services.

Published: April 2024

Background The “X+Y” residency scheduling model includes “X” weeks of uninterrupted inpatient or subspecialty rotations, followed by “Y” week(s) of uninterrupted outpatient rotations. The optimal ratio of X to Y is unclear.
Objective Determine the impact of moving from a 6+2 to a 3+1 schedule on patient access to care, perceived quality of care, and resident/faculty satisfaction.
Methods Our residency program switched from a 6+2 to a 3+1 scheduling model in July 2018. We measured access to care before and after the change using the “third next available” (TNA) metric. In June 2019, we administered a voluntary, anonymous, 20-item survey to residents, staff, and faculty who worked in resident clinic in both the 6+2 and 3+1 years.
Results Patient access to appointments with their resident physician, as measured by TNA, improved significantly after the schedule change (mean 34.1 days in 6+2, mean 26.5 days in 3+1, P&lt;.0001). Fifteen of 17 (88%) eligible residents and 13 of 24 (54%) faculty/staff filled out the voluntary anonymous survey. Surveyed residents and faculty/staff had concordant perception that the schedule change led to improvement in patient continuity, quality of care, and ability of residents to follow up on diagnostic tests and have regular interaction with clinic attendings. However, residents did not report a change in satisfaction with continuity clinic.
Conclusions Changing from a 6+2 to a 3+1 schedule was associated with improvement in patient access to care. Residents and faculty/staff perceived that this schedule change improved several aspects of patient care.

Este artigo traz como objeto de estudo a orientação sobre a não utilização de adornos por acadêmicos de medicina no campo da prática oferecido pela instituição de ensino. A ideia inicial desse estudo partiu da aula de Aprendizagem Baseada em Projetos (PjBL), onde os acadêmicos do primeiro período deveriam desenvolver um produto educacional para orientar os próximos calouros, quanto a biossegurança. O objetivo geral desse estudo é conscientizar os acadêmicos de medicina a não usar adornos no campo de prática. Os objetivos específicos são: descrever as principais consequências causadas pelo uso de adornos; apresentar um vídeo educacional mostrando a importância do não uso de adornos, elaborado pelos alunos do PjBL. Este estudo foi elaborado em 2 tempos. Para elaboração do texto e do conteúdo do vídeo educacional, utilizou-se a pesquisa de revisão bibliográfica. Após a elaboração do conteúdo escrito, partiu-se para a elaboração do material visual. Foram selecionados artigos em português, com lapso temporal de 2019 a 2023, utilizando os descritores infecção hospitalar, equipamento de proteção individual e a palavra chave adornos. Foram encontrados para o descritor equipamento de proteção individual 26 artigos, e, para infecção hospitalar 38 artigos. As escolhas foram feitas após leitura do título e resumo. A segunda etapa que pertence a elaboração do vídeo educacional, com público alvo a se atingir. Percebe-se que a quantidade de pessoas que entram na instituição educacional, em sua maioria, são jovens entre 17 a 25 anos (também os mais velhos), com um vídeo curto da plataforma tiktok com a música de fundo “dança da mãozinha”, onde o refrão oferece a possibilidade de acrescentar tópicos de relevância do tema, em flash rápido. A principal problemática do uso de adornos é a microbiota que se mantêm presa a eles, e sua transmissão durante o toque torna-se comum. O uso de esmalte, unhas em gel, dificultam a higienização completa e eficaz das mãos o que também pode contribuir. No ambiente hospitalar, essa transmissão de microorganismos pode desencadear infecções hospitalares. A NR32 tem por finalidade estabelecer e regulamentar as diretrizes básicas para a implementação de medidas de proteção à segurança e à saúde dos trabalhadores dos serviços de saúde, principalmente aqueles que mantêm contato com agentes biológicos . Por tudo isso, pensa-se sobre a necessidade de ações promotivas e preventivas que ensinam “boas práticas” e assim, o académico consegue de forma consciente, reproduzir condutas que serão primordias para evitar a disseminação de doenças no ambiente de saúde, que além de cumprir na sua vida acadêmica como aluno, irá realizar após formado, e poderá ser um agente transformador no seu ambiente de trabalho.
Assessment of Community Radio Social Impact in Tanzania
Authors: Mpehongwa Gasper 
Published: April 2024

Purpose: This paper assessed social impacts of three community radio stations located in three different social-economic zones in Tanzania namely, Kilosa in the Eastern Zone, Karagwe in the Lake Victoria Zone and Orkonerei Community Radio (ORS) in the Northern Zone.
Methodology: The study used cross sectional design whereby data were collected at one point in time. Purposive sampling methods were used to obtain 585 (48% female) respondents based on whether the area was well covered by community radio broadcasts or otherwise. Data were collected interview schedule, in-depth interview of key informants, systematic observations and focus group discussions. Key informants included community radio management and journalists working in the community radios. As for focus group discussions, four discussions were held (two in each community radio) with a total of 40 respondents.
Findings: The study found that 51% of the respondents viewed community radio stations as enhanced access to information (news, current affairs and educational informational). On popularity, the study found that on average, community radios were more popular with local audience than other radio stations. This was due to broadcasting local contents. An analysis of sex and education levels of people who preferred community radio showed that 53.4% were men and 46.5% were women. As for education levels, 57% of those who preferred community radio broadcast had primary education followed by those without formal education at 24%. However, contrary to the theory of community radio which asserts that community radios focus on local social economic development, the study found that the most dominant theme was music and general entertainment.
Unique Contribution to Theory, Practice and Policy: The study found that community radio stations have enhanced information flow (news, current affairs and education). They are also most popular with local audience compared to other radios. This indicates that if tailored to address contemporary local development issues, community radio can have huge impact. However, the study found that, the most dominant themes in studied stations was music and general entertainment. This is contrary to the theory asserting that community radio should focus on local social development issues. This calls for further investigation on circumstances leading community radios deviation from the popular theory.

Authors: BOARATI Sandra Rodrigues Sarro , CASTRO Marcus Cesar Avezum Alves de 
Published: April 2024

RESUMO - O biogás gerado em aterros sanitários é uma fonte renovável e pode ser utilizado para gerar calor ou eletricidade, apresentando um alto percentual energético e trazendo benefícios econômicos aliados ao saneamento ambiental. O objetivo deste trabalho foi analisar a composição do biogás gerado, relacionando-a com o tempo de aterramento dos resíduos sólidos dispostos no aterro sanitário de Rio Claro/SP. Realizou-se a análise comparativa da temperatura, influência da precipitação pluviométrica na vazão e na concentração de metano (CH4) e de dióxido de carbono (CO2) do biogás no período de 18 meses. Conclui-se que a produção de biogás foi menor em áreas mais antigas. A influência da precipitação na geração de biogás foi mais acentuada em células com menor tempo de disposição no aterro. Os valores crescentes de vazão de biogás sinalizam para o aumento da atividade biológica anaeróbia.

ABSTRACT - Biogas generated in landfills is a renewable source and can be used to generate heat or electricity with a high energy percentage bringing economic benefits combined with environmental sanitation. The objective of this work was to analyze the composition of the generated biogas, relating it to the grounding time of the solid residues disposed in the sanitary landfill of Rio Claro/SP. A comparative analysis of temperature, influence of rainfall on the flow and concentration of methane (CH4) and carbon dioxide (CO2) of the biogas in the period of 18 months was carried out. It is concluded that biogas production was lower in older areas. The influence of precipitation on biogas generation was more pronounced in cells with less disposal time in the landfill. The increasing values of biogas flow indicate an increase in anaerobic biological activity.

Abstract. A tropospheric O3 pollution episode over the Atlantic coast of the Iberian Peninsula during 2–6 August 2018 has been analyzed. The episode was characterized by a permanent wind shear throughout the entire period, making the observed ozone surface distribution especially difficult to explain. A new methodology is described to analyze upper-level atmospheric parameters, such as temperature, wind direction, wind speed, and O3 concentrations, added to the traditional use of surface parameters, using the Weather Research and Forecasting (WRF) and Comprehensive Air Quality Model with Extensions (CAMx) models as well as available surface and upper-air observations. Results indicate that the episode was characterized by a first phase of a sudden increase in O3 concentrations produced by fumigation and inter-regional transport processes within the Iberian Peninsula, followed by continental O3 transport from Europe to the Atlantic coast. An Atlantic front produced the dissipation of the episode, generating an “ozone front” accompanying the cold front passage across the region.

Abstract. Monitoring changes in glacial dynamics is essential for understanding the environmental response to accelerated climate warming in the Arctic. However, geodetic surveys in polar regions continue to present considerable challenges because of the harsh environmental conditions and the polar night. This study records a 14-year-long time series (2006–2019) of global navigation satellite system (GNSS) surveys of the positions of 16 ablation stakes distributed across Hansbreen, a tidewater glacier in southern Svalbard. The measurements were conducted with an exceptionally high temporal resolution, from about 1 week to about 1 month, and covering altitudes ranging from 20 to 490 m a.s.l. The position of one stake was surveyed every day. The primary data products consist of the stake coordinates and velocities. Time series of annual and seasonal velocities are also provided. This dataset may be a subject of further studies of glacier dynamics in relation to the long-term and seasonal impact of climate change on ice flow in the region. It also offers unique material for tuning numerical models of glacier dynamics and for validating satellite-derived products such as velocity and digital elevation models. The dataset described here has been made publicly available through the Zenodo repository: https://doi.org/10.5281/zenodo.8289380 (Błaszczyk et al., 2023).
Morphological characteristics and conditions of drainage basins contributing to the formation of debris flow fans: an examination of regions with different rock strength using decision tree analysis

Abstract. Debris flows cause severe disasters that can result in human casualties and the collapse of houses. The establishment of early warning systems in basins with high debris flow risks is needed to reduce the negative impacts of debris flow disasters. Because debris flows often form debris flow fans near the mouths of valleys, debris flow fans are regarded as important topographical elements that indicate the occurrence of debris flows. The presence or absence of a debris flow fan makes it possible to clarify the morphological conditions of the contributing area that has generated debris flows. These morphological conditions may depend on rock strength, which controls the weathering activity and grain size of sediments. In this study, we investigated the morphological conditions of a drainage basin that contribute to the formation of debris flow fans using decision tree analysis. The analysis was conducted at two sites with clear differences in rock strength due to geological processes: Neogene sedimentary rock and Paleogene accretionary complex sites. As a result of decision tree analysis using data sets containing a total of 158 basins, the thresholds of morphological parameters needed for forming debris flow fans differed depending on the geological features. When the relief ratio was less than 0.29 at the Paleogene accretionary complex site, coarse-grained sediments were less likely to pass out of the valley, resulting in the absence of debris flow fans. On the other hand, at Neogene sedimentary rock sites, short basins were determined to form debris flow fans, even if the relief ratio was less than 0.36, because the sediments were fine-grained and tended to flow downstream. In contrast, morphological factors that influence the presence or absence of debris flow fans were common at both sites. The first, second, and third most important morphological factors were the relief ratio, most frequent slope gradient, and basin length, respectively. Therefore, these morphological factors are considered important in evaluating debris flow risks. This study demonstrates that the decision tree analysis is an effective tool for determining the hierarchy and threshold of morphological factors that classify the presence or absence of debris flows that reach valley mouths.
