Abstract The potential of daylight harvesting is related to the building location. However, climatic zonings adopted by energy efficiency programs focus only on the thermal performance, neglecting important variables of the buildings’ luminous performance. This paper aims to investigate the relationship between the angle of solar incidence, the annual occurrence of clear sky, and the annual lighting energy consumption when daylight harvesting is practiced. The lighting consumption of a square floor space, orientated in the cardinal directions, was simulated for 20 Brazilian cities. The frequency of the 15 CIE sky types was determined for each city using weather files and the angle of solar incidence was calculated for each hour of the year. The analysis comprised graphical exploration, Pearson's correlation, and multiple regression. The sensitivity of the consumption to the other two variables could be perceived in the hourly but not the annual analysis. The correlation between annual consumption and latitude was more robust for the intertropical range, with increased consumption moving south, and varied significantly for each orientation. It was concluded that, although relevant, the variables are not representative of variations in annual lighting consumption for application in climate zoning.

O aproveitamento da luz natural está relacionado à localização do edifício. Tadavia, os zoneamentos climáticos dos programas de eficiência energética focam no desempenho térmico, negligenciando importantes variáveis do desempenho luminoso das edificações. Este trabalho objetivou investigar a relação entre o ângulo de incidência solar, a ocorrência anual de céu claro e o consumo anual de iluminação, considerando o aproveitamento da luz natural. Simulou-se o consumo de iluminação de um ambiente quadrado, orientado aos pontos cardeais, para 20 cidades brasileiras. Determinou-se a frequência dos 15 tipos de céu CIE para cada cidade, usando-se arquivos climáticos, e calculou-se o ângulo de incidência solar para cada hora do ano. A análise compreendeu exploração gráfica, correlação de Pearson e regressão múltipla. A sensibilidade do consumo às outras duas variáveis pode ser percebida na análise horária, mas não na anual. A correlação entre consumo anual e latitude foi mais robusta para a faixa intertropical, com o consumo aumentando para o sul, e variando significativamente para cada orientação. Concluiu-se que, embora relevantes, as variáveis não são representativas das variações de consumo anual de iluminação para aplicação em zoneamentos climáticos.

Abstract Mucormycosis is a low-prevalence, rapidly progressive and high-mortality pathology that encompasses a wide spectrum of opportunistic infections caused by fungi of the Mucoraceae, Lichtheimiaceae, Thamnidiaceae, Cunninghamellaceae, Syncephalastraceae, and Radiomycetaeae. It is currently the third cause of invasive fungal infection, after candidiasis and aspergillosis, with its most frequent clinical presentation being rhinocerebral of paranasal origin, whose characteristic symptom is acute bacterial rhinosinusitis with projection to the antral teeth, with rapid progression and fatality. In this review, manually extracted results from articles indexed in the MEDLINE and EBSCO databases were used following the search for the terms mucormycosis, oral surgery and patient care management with the aim of providing an updated view of the literature regarding the diagnosis and treatment of mucormycosis of the head and neck.

Resumen La mucormicosis, es una patología de baja prevalencia, rápidamente progresiva y de alta mortalidad que engloba un amplio espectro de infecciones del tipo oportunistas, causada por hongos de la familia Mucoraceae, Lichtheimiaceae, Thamnidiaceae, Cunninghamellaceae, Syncephalastraceae y Radiomycetaeae. Actualmente es la tercera causa de infección fúngica invasiva, posterior a la candidiasis y aspergilosos, siendo su presentación clínica más frecuente la rinocerebral de origen paranasal, cuyo síntoma característico es la rinosinusitis aguda bacteriana con proyección a los dientes antrales, de rápido avance y fatalidad. En esta revisión se emplearon resultados extraídos manualmente de artículos indexados en las bases de datos MEDLINE y EBSCO a raíz de la búsqueda de los términos mucormycosis, oral surgery y patient care management con el objetivo de entregar una visión actualizada de la literatura, respecto al diagnóstico y tratamiento de la mucormicosis de cabeza y cuello.

Abstract To compare the prevalence of hospitalizations and deaths due to Leishmaniasis among Brazilian regions from 2010 to 2020. This is a retrospective, descriptive, quantitative, documentary-based study. Data were obtained from the SUS Hospital Information System (SIH/SUS), by the SUS IT Department (DATASUS). In the period evaluated, 32.320 hospitalizations for Leishmaniasis were recorded in Brazil. Visceral leishmaniasis comprised the majority of hospitalizations 25.761 (79.70%). However, the highest numbers of hospitalizations occurred in the Northeast (42.82%) and Southeast (19.91%) for visceral leishmaniasis, Southeast (37.29%) and Northeast (33.42%) for Cutaneous Leishmaniasis and Southeast (42.82%) and Northeast (22.94%) due to mucocutaneous leishmaniasis. There was a predominance of males and brown color/race. A total of 1.193 deaths were observed. The highest number of deaths occurred in patients hospitalized for visceral leishmaniasis (1.086/91.03%). Leishmaniasis and, consequently, hospitalizations and deaths due to this pathology, cause a considerable impact on the public health system in Brazil, generating high costs for the country. Thus, government measures are needed to stimulate health promotion actions for disease prevention.

Resumo Comparar as prevalências das internações e óbitos por Leishmaniose entre as regiões brasileiras no período de 2010 a 2020. Trata-se de um estudo retrospectivo, descritivo, quantitativo, de base documental. As variáveis utilizadas foram: sociodemográficas (sexo, faixa etária e etnia) e clínicas (número de internações e média de permanência, taxa de mortalidade, caráter, regime de atendimento e custos das internações). Os dados foram obtidos do Sistema de Informações Hospitalares do SUS (SIH/SUS), pelo Departamento de informática do SUS (DATASUS). No período avaliado, foram registradas 32.320 internações por Leishmaniose no Brasil. A Leishmaniose visceral compondo a maior parte das internações 25.761 (79.70%). No entanto, os maiores números de internações ocorreram nas regiões Nordeste (42.82%) e Sudeste (19.91%) pela Leishmaniose visceral, Sudeste (37.29%) e Nordeste (33.42%) na Leishmaniose Cutânea e Sudeste (42.82%) e Nordeste (22.94%) pela Leishmaniose mucocutânea. Houve predomínio no sexo masculino e cor/raça parda. Observou-se um total de 1.193 óbitos. O maior número de óbitos ocorreu nos pacientes internados por Leishmaniose visceral (1.086/91.03%). As Leishmanioses e, consequentemente as internações e óbitos em decorrência dessa patologia, ocasiona considerável impacto no sistema público de saúde do Brasil, gerando altos custos para o país. Dessa forma, são necessárias medidas governamentais, com objetivo de estimular ações de promoção de saúde prevenção de doenças.

SUMMARY: In the last decade, forensic odontology has focused on the development of age estimation (AE) methodologies due to the great request in identification processes. Among these techniques, the tooth cementum annulation (TCA) count method has offered promising but also contradictory results, raising questions about its accuracy and reliability. The aim of this work was to characterize, establish the scope, and identify the limitations of the TCA count method according to the current normative and methodological standards. A scoping review was carried out for TCA count methods for AE, including experimental studies and technical notes in the PubMed/Medline, Scopus, Web of Science (WoS) and Embase databases. The terms "estimation”, “age” and “cementum” were used, with a complementary manual search in Google Scholar. Reviews, studies in archaeological collections, radiological studies and letters to the editor were excluded. The search yielded a total of 273 articles, selecting 27 of them that met the inclusion criteria. Most of the studies were published in Asia, particularly India (n=21). Only 6 articles declared the total number of individuals, types of teeth, and histological sections, with the premolar being the most studied. Only two articles evaluated the quality of the sample to be analyzed through the legibility of the cuts obtained. The most widely used test to assess the precision of the method was the Pearson correlation coefficient (n=21). These findings expose the high heterogeneity reported in EE methodologies by counting TCA, so there is still no standardized process that covers in all its stages and delivers reliable results following current legal standards for scientific evidence. More control of the detected technical limitations will increase the value as evidence in a legal or forensic identification context.

RESUMEN: En la última década, la odontología forense se ha enfocado en el desarrollo de metodologías para la estimación de edad (EE) debido a la gran demanda en procesos identificatorios. Entre esas técnicas, el conteo de anulaciones del cemento dental (TCA) ha ofrecido resultados promisorios, pero también contradictorios que han generado dudas sobre su precisión y confiabilidad. El objetivo de este trabajo fue caracterizar, establecer alcances, e identificar las limitaciones del conteo de TCA según los actuales estándares normativos y metodológicos. Se realizó una revisión con búsqueda sistemática del método de conteo de TCA para EE incluyendo estudios experimentales y notas técnicas en las bases PubMed/Medline, Scopus, Web of Science (WoS) y Embase. Se emplearon los términos “estimation”, “age” y “cementum”, con búsqueda manual complementaria en Google Scholar. Se excluyeron revisiones, estudios en colecciones arqueológicas, estudios radiológicos y cartas al editor. La búsqueda arrojó un total de 273 artículos, seleccionándose 27 que cumplieron con los criterios de inclusión. La mayoría de los estudios fueron publicados en Asia, particularmente en India (n=21). Sólo 6 artículos declararon el número total de individuos, tipos de diente y de cortes histológicos, siendo el premolar el más estudiado. Apenas dos artículos evaluaron la calidad de la muestra a analizar mediante legibilidad de los cortes obtenidos. El test más empleado para evaluar la precisión del método fue el coeficiente de correlación de Pearson (n=21). Estos hallazgos exponen la alta heterogeneidad reportada en las metodologías de EE mediante conteo por TCA, por lo que aún no existe un proceso estandarizado que abarque todas sus etapas y entregue resultados confiables siguiendo los estándares jurídicos actuales para la evidencia científica. Un mayor control de las limitaciones técnicas detectadas aumentará el valor como prueba en un contexto identificatorio legal o forense.

RESUMEN: El objetivo de este estudio fue comparar el tiempo empleado al estimar la edad dental (ED) entre el método propuesto por Demirjian et al. y el cuadro integral del enfoque de Demirjian (DAEcc) utilizando radiografías panorámicas digitales de individuos peruanos de 5 a 13 años residentes en Lima. Se realizó un estudio no experimental, comparativo, transversal y retrospectivo. Se utilizaron 100 radiografías panorámicas digitales que presentaban siete dientes permanentes mandibulares izquierdos. Una odontóloga forense capacitada y calibrada determinó el tiempo utilizado en evaluar la maduración dental y la estimación de ED con dos métodos (Demirjian y DAEcc). La unidad de medida utilizada fue los minutos (min.). No hubo diferencias en el tiempo de evaluación del estadio de maduración dental entre ambos métodos (p<0,05). El tiempo para estimar ED fue estadísticamente inferior con DAEcc (2,09 min) que con Demirjian (4,19 min). La diferencia del tiempo total de evaluación resultó estadísticamente significativa entre ambos métodos (Δ2,1 min.; 2,05-2,11; p=0,000). La aplicación del DAEcc redujo en 50 % el tiempo empleado en estimar ED en comparación con los cuadros propuestos por Demirjian. Aunque la odontología forense se centra en el estudio de la eficacia de estimación de la edad, es necesario abordar también su uso práctico.

SUMMARY: The objective of this study was to compare the time used to estimate dental age (DA) between the method proposed by Demirjian et al., and the comprehensive chart for dental age estimation (DAEcc) using digital panoramic radiographs of Peruvian individuals aged 5 to 13 years residing in Lima. A non- experimental, comparative, cross-sectional and retrospective study was carried out. 100 digital panoramic radiographs showing seven mandibular left permanent teeth were used. A trained and calibrated forensic odontologist determined the time used to assess tooth maturation and DA estimation with two methods (Demirjian and DAEcc). The unit of measurement used was minutes (min.). There were no differences in the evaluation time of the dental maturation stage between both methods (p<0.05). The time spent to estimate DA was statistically less with DAEcc (2.09 min) than with Demirjian (4.19 min). The difference in total evaluation time was statistically significant between both methods (Δ2.1 min; 2.05-2.11; p=0.000).The application of DAEcc reduced by 50 % the time spent estimating DA compared to the method proposed by Demirjian. Although forensic odontology focuses on the study of the effectiveness of age estimation, its practical use needs to be addressed as well.

Abstract The scope of this study was to analyze the factors associated with the use of dental services in Brazil. The review strategy included PubMed, SciELO, LILACS, BBO, EMBASE, Scopus, WOS and Google Scholar databases, in addition to repositories and databases of dissertations and theses. Studies were selected using the PEO (Population/Exposure/Outcomes) strategy. The outcome of this study was the use of dental services in the last year by the Brazilian population, treated as dichotomous variables for the following analyses: ≤ 1 year and > 1 year. Mantel-Haenszel random effect meta-analysis was performed, estimating Prevalence Ratios (PR) and 95% confidence intervals (95%CI). A total of 94 studies were selected. The majority (98%) had a cross-sectional design, with 63% derived from primary data. For the meta-analysis, 25 studies were included. The use of oral health services in the last year was associated with higher education (≥ 8 years of schooling) (PR = 0.49, (95%CI: 0.39-0.60)); higher family income (≥ 2 minimum wages) (RP = 0.79, (95%CI: 0.74-0.84)); and living in urban areas (RP = 0.79, (95%CI: 0.64-0.97)). The availability of dental services in the Unified Health System needs to be made readily accessible to people with lower income, less education and those living in rural areas.

Resumo O objetivo foi analisar os fatores associados ao uso dos serviços odontológicos no Brasil. A estratégia de revisão incluiu as bases PubMed, SciELO, LILACS, BBO, EMBASE, Scopus, WOS e Google Scholar, além de repositórios e bancos de dissertações e teses. Os estudos foram selecionados usando a estratégia PEO (população/exposição/desfechos). O desfecho deste estudo foi o uso dos serviços odontológicos no último ano pela população brasileira, tratado como variáveis dicotômicas para as análises: ≤ 1 ano e > 1 ano. Foi realizada uma metanálise de efeito randômico de Mantel-Haenszel, estimando-se razões de prevalência (RP) e intervalos de confiança de 95% (IC95%). Foram selecionados 94 estudos. A maioria (98%) tinha delineamento transversal, sendo 63% oriundos de dados primários. Para a metanálise, 25 estudos foram incluídos. O uso dos serviços odontológicos no último ano esteve associado com maior escolaridade (≥ 8 anos de estudo) (RP = 0,49, (IC95%: 0,39-0,60)); maior renda familiar (≥ 2 salários-mínimos) (RP = 0,79, (IC95%: 0,74-0,84)); e residir na zona urbana (RP = 0,79, (IC95%: 0,64-0,97)). A oferta de serviços odontológicos no Sistema Único de Saúde precisa ser ampliada entre pessoas com menor renda, menor escolaridade e moradores da zona rural.

ABSTRACT Purpose Bladder endometriosis (BE) accounts for 84% of cases of urinary tract involvement. The use of cystoscopy for preoperative evaluation is limited. The aim of this study was to evaluate the accuracy of preoperative dynamic cystoscopy (DC) in patients undergoing surgery for deep endometriosis and to describe the main findings and their impact on surgical planning. Materials and Methods This cross-sectional observational study was conducted from January 2011 to March 2022. DC findings were divided into two groups according to the depth of involvement. To estimate sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), laparoscopic findings of bladder involvement and histopathological report were used as the gold standard. Results We included 157 patients in this study. 41 had abnormalities in DC. Of these, 39 had abnormalities that were confirmed intraoperatively. The sensitivity and specificity of the test were 58.21% and 97.78%, respectively. PPV was 95.12%, and NPV was 75.86%. The presence of any lesions in the DC had a diagnostic odds ratio (OR) of 61.28 for BE. Patients with BE type 2 had a higher rate of partial cystectomy than those with BE type 1 lesions (OR 9.72 CI 95% 1.9-49.1) Conclusion DC appears to be a highly specific test with lower sensitivity. DC abnormalities are associated with a higher ratio of bladder surgery for the treatment of deep endometriosis, and BE type 2 seems to be associated with a greater ratio (9.72) of partial cystectomy.

SUMMARY OBJECTIVE: The aim of this study was to evaluate serum 25(OH)D concentrations in the homebound elderly people and relate them to level of dementia, nutritional risk, and route of dietary administration. METHODS: This is a cross-sectional study involving 207 bedridden elderly people assisted by the Home Care Service in the city of Santo André – SP, from June to December 2016. The following factors were evaluated: dietary intake of vitamin D, arm circumference, triceps skin fold thickness, calf circumference, nutritional risk by Mini-Nutritional Assessment, level of dementia by the adapted Clinical Dementia Rating questionnaire, and laboratory tests such as serum concentrations of 25(OH)D, ultrasensitive C-reactive protein, alkaline phosphatase, serum calcium, and parathormone. RESULTS: The mean age of the elderly people was 81.6 (9.2) years. Deficiency of 25(OH)D was observed in 76.3% of the elderly people. There was an inverse correlation between serum concentrations of 25(OH)D: parathormone (r=-0.418, p<0.001) and alkaline phosphatase (r=-0.188, p=0.006) and a direct correlation with serum calcium (r=-0.158, p=0.022). Logistic regression showed that vitamin D deficiency was directly and independently associated with oral feeding (odds ratio 7.71; 95%CI 2.91–20.40). CONCLUSION: Bedridden households showed high prevalence of vitamin D deficiency without association with nutritional risk and level of dementia. Oral diet was associated with vitamin D deficiency, possibly due to low consumption of source foods.

ABSTRACT The use of echocardiography by physicians who are not echocardiographers has become common throughout the world across highly diverse settings where the care of acutely ill patients is provided. Echocardiographic evaluation performed in a point-of-care manner can provide relevant information regarding the mechanism of causes of shock, for example, increasing the rates of correct diagnosis and allowing for faster informed decision-making than through evaluation methods. Considering that the accurate diagnosis of life-threatening situations is essential for professionals working with acutely ill patients, several international associations recommend that physicians responsible for critically ill patients acquire and develop the ability to perform bedside ultrasound examinations, including echocardiographic examinations. However, there is no consensus in the literature regarding which specific applications should be included in the list of skills for nonechocardiographer physicians. Taking into account the multiplicity of applications of echocardiography in different scenarios related to acutely ill patients; the differences in the published protocols, with regard to both the teaching methodology and competence verification; and the heterogeneity of training among highly diverse specialties responsible for their care at different levels, this consensus document aimed to reflect the position of representatives of related Brazilian medical societies on the subject and may thus serve as a starting point both for standardization among different specialties and for the transmission of knowledge and verification of the corresponding competencies.

RESUMO O emprego da ecocardiografia por médicos não ecocardiografistas tem se tornado comum em todo o mundo nos mais diversos ambientes em que se dá o cuidado do paciente agudamente doente. A avaliação ecocardiográfica realizada de forma point-of-care pode fornecer informações pertinentes em relação ao mecanismo das causas de choque, por exemplo, incrementando as taxas de diagnóstico correto e possibilitando a tomada de decisão fundamentada de forma mais rápida do que por meio dos métodos tradicionais de avaliação. Considerando que o diagnóstico preciso de situações ameaçadoras à vida é indispensável a profissionais atuando junto a pacientes agudamente enfermos, diversas entidades associativas internacionais recomendam que médicos responsáveis por pacientes gravemente doentes devam adquirir e desenvolver a habilidade para realizar exames ultrassonográficos à beira do leito, inclusive ecocardiográficos. Entretanto, não há consenso na literatura acerca de quais aplicações específicas devam compor o rol de habilidades do médico não ecocardiografista. Levando-se em consideração a multiplicidade de aplicações da ecocardiografia em diversos cenários relativos ao paciente agudamente enfermo; as diferenças nos protocolos publicados, tanto no que diz respeito à metodologia de ensino como de verificação de competências, bem como a heterogeneidade da formação entre as mais diversas especialidades responsáveis pelo seu cuidado em diferentes níveis, este documento de consenso teve o objetivo de refletir o posicionamento de representantes de sociedades médicas brasileiras afins acerca do tema, podendo, assim, servir de ponto de partida para a uniformização entre diferentes especialidades, bem como para a transmissão de conhecimento e a verificação das competências correspondentes.

ABSTRACT OBJECTIVE To compare the incidence of covid-19 symptoms between informal home-based workers and a control group and to assess the association of these cases with blood elements concentrations and other relevant risk factors for Sars-Cov-2 infection. METHODS Welders chemically exposed to potentially toxic elements (PTEs) (n = 26) and control participants (n = 25) answered questionnaires on adherence to social distancing and signs and symptoms of the disease for five months during the covid-19 pandemic. After follow-up, covid-19 serology tests were performed on a subsample of 12 chemically exposed workers and 20 control participants. Before the pandemic, PTE concentrations in blood (As, Mn, Ni, Cd, Hg, Sb, Sn, Cu, Zn, and Pb) were measured by ICP-MS. RESULTS The chemically exposed group had higher lead and cadmium levels in blood (p < 0.01). The control group presented lower adherence to social distancing (p = 0.016). Although not significant, welders had a 74% greater chance of having at least one covid-19 symptom compared with control participants, but their adherence to social distancing decreased this chance by 20%. The use of taxis for transportation was a risk factor significantly associated with covid-19 symptoms. CONCLUSION The lower adherence to social distancing among the control group greatly influences the development of covid-19. The literature lacks data linking exposure to PTEs and Sars-Cov-2 infection and/or severity. In this study, despite chemical exposure, working from home may have protected welders against covid-19, considering that they maintained greater social distancing than control participants.

The results obtained in this study allow us to affirm that the MIR exam is an objective exam, of adequate difficulty and discrimination, as well as relatively stable from one call to another.

ABSTRACT BACKGROUND: Bariatric surgery is the best treatment option for patients with obesity. As a result of the advancement of technology, the robotic gastric bypass presents promising results, despite its still high costs. AIMS: The aim of this study was to compare patients submitted to a robotic versus a laparoscopic gastric bypass at a single center by a single surgeon. METHODS: This retrospective study collected data from the medical records of 221 patients (121 laparoscopic procedures versus 100 with daVinci platform). The variables analyzed were sex, age, body mass index, comorbidities, surgical time, length of stay, and complications. RESULTS: The mean surgical time for patients in the robotic group was shorter (102.41±39.44 min versus 113.86±39.03 min, p=0.018). The length of hospital stay in robotic patients was shorter (34.12±20.59 h versus 34.93±11.74 h, p=0.007). There were no serious complications. CONCLUSIONS: The group submitted to the robotic method had a shorter surgical time and a shorter hospital stay. No difference was found regarding strictures, bleeding, or leakage.

RESUMO RACIONAL: A cirurgia bariátrica é a melhor opção de tratamento para pacientes portadores de obesidade. Em decorrência do avanço da tecnologia, o bypass gástrico robótico apresenta resultados promissores, apesar de seus custos ainda elevados. OBJETIVOS: Comparar pacientes submetidos a bypass gástrico robótico versus laparoscópico em um único centro por um único cirurgião. MÉTODOS: Estudo retrospectivo com coleta de dados dos prontuários de 221 pacientes (121 procedimentos laparoscópicos vs 100 com plataforma daVinci). As variáveis analisadas foram sexo, idade, IMC, comorbidades, tempo cirúrgico, tempo de internação e complicações. RESULTADOS: O tempo cirúrgico médio dos pacientes do grupo robótico foi menor (102,41 ± 39,44 min. vs 113,86±39,03 min, p=0,018). O tempo de internação em pacientes robóticos foi menor (34,12±20,59 h vs 34,93±11,74 h, p=0,007). Não houve complicações graves. CONCLUSÕES: O grupo submetido ao método robótico apresentou menor tempo cirúrgico e menor tempo de internação. Nenhuma diferença foi encontrada na amostra em relação a estenoses, sangramento ou vazamento.
