Abstract There are several characteristics that influence fire resistance of load-bearing masonries, wherein stand out the bricks compressive strength. Verification of wall systems fire behavior was conducted as prescribed by NBR 5628. This research aims to comparatively analyze fire resistance in real scale load-bearing walls, considering thermal insulation, structural stability, and airtightness. The thickness of the coating and laying mortar were standardized for all specimens just varying brick geometry and septs design in blocks of EST 60, 100, and 140 class. The obtained results show that the compressive strength of the bricks can induce both the structural stability of the constructive systems and its thermal insulation, being a typically critical characteristic for clay brick walls in a building fire. The sample with the highest compressive strength obtained the shortest local displacement, contributing to mitigate the generation of fissures in the system, enhancing the thermal insulation of the clay brick wall, and, thereby, its fire resistance.

Resumo Diversas características influenciam a resistência ao fogo de sistema de parede em alvenaria estrutural, dentre as quais pode se incluir sua resistência à compressão. O comportamento desse sistema é validado experimentalmente conforme a norma NBR 5628. Esse estudo tem como objetivo analisar comparativamente a resistência ao fogo obtida através de ensaios em escala real em alvenaria estrutural, envolvendo as características de isolamento térmico, estanqueidade a passagem de gases e fumaça e estabilidade estrutural. Foram avaliados componentes com a mesma configuração em termos de revestimento e assentamento, assumindo como variável a resistência a compressão dos blocos, tendo sido considerados neste estudo blocos de classe EST 60, 100 e 140. Os resultados obtidos apontam que a resistência à compressão da alvenaria pode influenciar, além da estabilidade estrutural do sistema, também seu isolamento térmico, critério tipicamente crítico para alvenarias de blocos cerâmicos em situação de incêndio. A amostra de maior resistência à compressão apresentou menor deslocamento horizontal, contribuindo para mitigar a geração de fissuras, aumentando a oposição da alvenaria à passagem da temperatura ao longo de sua seção transversal e assim aumentar sua resistência ao fogo.

Community-led monitoring (CLM) of health services is a mechanism of community participation and accountability that is increasingly advocated across the globe. In South Africa (SA), a large-scale community-led monitoring initiative called Ritshidze ('saving our lives') was established in 2019. Steered by a coalition of civil society organisations representing people living with HIV, Ritshidze monitors just over 400 primary healthcare (PHC) facilities in 8 provinces on a quarterly basis. In this piece we describe the purposes and design features and the five-step approach to CLM of the Ritshidze model. We also highlight some of the positive changes achieved, and reflect on possible reasons for successes. In doing so, we aim to draw attention to this significant national initiative and its potential as a mechanism of social accountability in SA.

ABSTRACT: Protocols to artificially induce cows and heifers into lactation are effective and commercially available in Brazil. However, these protocols demand long hormonal treatments, which is debatable since little research has been done in the subject. To further understand artificial induction to lactation (AIL) protocols, we conducted two experiments. In experiment 1, our objective was to better characterize steroidal profile during an AIL protocol and assess the estradiol (E2) and progesterone (P4) serum profiles of Jersey cows (n=6) subjected to a conventional protocol. In experiment 2, we aimed to compare milk production and serum E2 concentrations of Holstein heifers induced into lactation by the standard AIL protocol (15 injections of E2 and 8 P4 injections) and by a short protocol in which the number of E2 injections and, consequently, the overall dosage of E2, were reduced (8 injections of E2 and 8 P4 injections). We hypothesized that a short AIL protocol (8 days) would be as efficient as the long standard protocol of 15 days. Our hypothesis was confirmed, since we demonstrated that a shorter protocol was able to induce lactation in Holstein heifers without hindering milk production.

RESUMO: Protocolos que induzem à lactação artificial em vacas e novilhas são eficazes e estão comercialmente disponíveis no Brasil. No entanto, esses protocolos demandam longos tratamentos hormonais, o que é discutível visto que poucas pesquisas foram feitas sobre o assunto. Para entender melhor os protocolos de indução artificial à lactação (IAL), realizamos dois experimentos. Foi testada a hipótese de que um protocolo curto (oito dias) de IAL é tão eficiente quanto o protocolo padrão de 15 dias. No experimento 1 objetivou-se caracterizar o perfil esteroidal durante um protocolo de IAL e avaliou-se os perfis séricos de estradiol (E2) e progesterona (P4) de vacas Jersey (n=6) submetidas a um protocolo convencional. No experimento 2 foram comparadas a produção de leite e as concentrações séricas de E2 de novilhas holandesas induzidas à lactação pelo protocolo padrão de IAL (15 injeções de E2 e 8 injeções de P4) e por um protocolo curto, no qual o número de injeções de E2 e, consequentemente, a dosagem geral de E2 foram reduzidas (oito injeções de E2 e oito injeções de P4). A hipótese foi confirmada, demonstrado que um protocolo mais curto induziu a lactação em novilhas holandesas sem prejudicar a produção de leite.

ABSTRACT: This study evaluated the effect of black wattle (Acacia mearnsii) condensed tannin extract in simple and complex diets for weaned piglets on performance, faecal consistency and serum haptoglobin concentrations. Eighty-eight female and castrated male piglets were used, weaned at 28 ± 3 days old, with an initial body weight of 8.02 ± 1.21 kg, housed in same-sex pairs and distributed in four treatments in a 2 x 2 factorial experiment in a randomised complete block design. The experimental treatments were simple diet (SD), simple diet + tannin (SD+T), complex diet (CD) and complex diet + tannin (CD+T). The simple diets contained lower concentrations of dairy ingredients, inclusion of barley and no addition of zinc oxide, palatant, acidifier and yeast. The diets with tannin were supplemented with 1,850 mg kg-1 of black wattle condensed tannin extract. The feed programme consisted of three diets: Pre-starter I (0-7 days), Pre-starter II (8-21 days) and Starter (22-28 days). Feed and water were available ad libitum. Body weight and feed intake were measured weekly to calculate the average daily feed intake, daily weight gain and feed conversion ratio. The faecal consistency score was measured daily to calculate the diarrhoea occurrence percentage. Blood samples for serum haptoglobin concentration were collected at 7 and 14 days after weaning. The addition of condensed tannin had no effect (P > 0.05) on evaluated performance variables for weaned piglets. The diet type also did not affect the piglets’ performance (P > 0.05). The inclusion of black wattle (Acacia mearnsii) condensed tannin does not affect piglet performance, reduces the incidence of diarrhoea in the first week after weaning and decreases the haptoglobin inflammatory response.

RESUMO: O objetivo do estudo foi avaliar o efeito de extrato de tanino condensado de acácia-negra (Acacia mearnsii) no desempenho, consistência fecal e concentração sérica de haptoglobina em leitões na fase de creche. Foram utilizados 88 leitões desmamados aos 28±3 dias, com peso vivo médio inicial 8,02 ± 1,21 kg, alojados em duplas de mesmo sexo, e distribuídos em quatro tratamentos em um delineamento de blocos inteiramente ao acaso, em esquema fatorial 2 x 2. Os tratamentos experimentais foram: dieta simples (SD); dieta simples + tanino (SD+T); dieta complexa (CD) e dieta complexa + tanino (CD+T). As dietas simples foram formuladas com menores concentrações de derivados de leite, inclusão de cevada e sem adição de óxido de zinco, palatabilizante e levedura. As dietas com inclusão de tanino foram suplementadas com 1850 mg kg-1 de extrato concentrado de tanino de acácia negra. O programa alimentar foi constituído de três dietas: Pré-inicial I (0 a 7 dias), Pré-inicial II (8 a 21 dias) e Inicial (22 a 28 dias). Ração e água ficaram disponíveis ad libitum. O peso e o consumo de ração dos leitões foram mensurados semanalmente, para calcular a média diária de consumo, o ganho de peso diário e a conversão alimentar. O índice de consistência fecal foi medido diariamente para calcular a porcentagem de ocorrência de diarreia. Amostras de sangue para concentração sérica de haptoglobina foram coletadas aos sete e 14 dias após o desmame. A adição de tanino condensado não teve efeito (P > 0,05) no desempenho de leitões desmamados. O tipo de dieta também não afetou o desempenho dos leitões (P > 0,05). A inclusão do tanino condensado de acácia-negra (Acacia mearnsii) não afetou desempenho, reduziu a incidência de diarreia na primeira semana após o desmame, e diminuiu a resposta inflamatória da haptoglobina.

ABSTRACT Objective: To study associations between polymorphisms in the angiotensin converting enzyme (ACE I/D), actinin 3 (ACTN3 R577X) and paraoxonase 1 (PON1 T(-107)C) genes and chronic diseases (diabetes and hypertension) in women. Materials and methods: Genomic DNA was extracted from saliva samples of 78 women between 18 and 59 years old used for genetic polymorphism screening. Biochemical data were collected from the medical records in Basic Health Units from Southern Brazil. Questionnaires about food consumption, physical activity level and socioeconomic status were applied. Results: The XX genotype of ACTN3 was associated with low HDL levels and high triglycerides, total cholesterol and glucose levels. Additionally, high triglycerides and LDL levels were observed in carriers of the TT genotype of PON1, and lower total cholesterol levels were associated to the CC genotype. As expected, women with diabetes/hypertense had increased body weight, BMI (p = 0.02), waist circumference (p = 0.01), body fat percentage, blood pressure (p = 0.02), cholesterol, triglycerides (p = 0.02), and blood glucose (p = 0.01), when compared to the control group. Conclusion: Both ACTN3 R577X and PON1 T(-107)C polymorphisms are associated with nutritional status and blood glucose and lipid levels in women with diabetes/hypertense. These results contribute to genetic knowledge about predisposition to obesity-related diseases.

Abstract The aim of this study was to evaluate the influence of adding quaternary ammonium methacrylates (QAMs) to experimental adhesives by assessing the degree of conversion (DC), cytotoxicity against keratinocytes and fibroblasts, and antibacterial activity against biofilm formation. Two QAMs were added to an experimental adhesive: dimethylaminododecyl methacrylate bromododecane (DMADDM) or dimethylaminododecyl methacrylate bromohexadecane (DMAHDM) at three concentrations each: 1, 2.5, and 5 wt.%. Experimental adhesive without QAMs (control group) and commercially available Transbond XT Primer (3M Unitek, Monrovia, California, USA) were used for comparisons. The adhesives were tested for DC, cytotoxicity against keratinocytes and fibroblasts, and antibacterial activity against biofilm formation. DC, cytotoxicity against fibroblasts, and antibacterial activity were analyzed using one-way ANOVA and Tukey’s multiple comparisons. Cytotoxicity against keratinocytes was evaluated using the Kruskal Wallis and Dunn’s post-hoc (α = 5%) tests. Transbond showed lower DC as compared to 5% DMAHDM, 1% DMADDM, and 5% DMADDM (p < 0.05). However, all groups presented proper DC when compared to commercial adhesives in the literature. In the evaluation of cytotoxicity against keratinocytes, Transbond induced higher viability than 2.5 wt.% groups (p < 0.05). Against fibroblasts, Transbond induced higher viability as compared to 5 wt.% groups (p < 0.05). DMAHDM at 5 wt.% reduced biofilm formation when compared to all the other groups (p < 0.05). Despite their cytotoxic effect against keratinocytes, gingival fibroblasts showed higher viability. DMAHDM at 5 wt.% decreased Streptococcus mutans viability. The incorporation of DMAHDM at 5 wt.% may be a strategy for reducing the development of white spot lesions.

ABSTRACT: Pythiosis is the disease caused by aquatic oomycetes of the genus Pythium. In dogs the typical course of the disease involves the gastrointestinal tract, characterized by transmural thickening of the stomach or intestines. However, infection by Pythium spp. has only rarely been recognized as a cause of esophagitis in dogs. Thus, the present reports a case of esophageal and gastric pythiosis in an eight-month-old female pit bull dog. The dog was attended at the hospital after two months presenting regurgitation and dyspnea. It was reported that the dog lived in an urban area and had no previous sanitary issues. At clinical examination it was noted that the dog presented crackling sounds at pulmonary auscultation. A support therapy accompanied by antibiotics has been employed; however, 22 days after hospitalization the clinical condition worsened, and the dog died. At necropsy, the wall of the distal segment of the esophagus and the cardia and part of the fundus of the stomach were expanded by a focal extensive irregular intramural annular mass. Additionally, there was a transmural esophageal fistula. At histology, the walls of the esophagus and stomach were extensively expanded by multifocal extensive areas of necrosis, associated with a pyogranulomatous infiltrate and abundant granulation tissue containing multiple negative images of hyphae that were highlighted by silver impregnation (Grocott). Furthermore, immunohistochemistry and PCR for P. insidiosum were both positive in samples of paraffin-embedded esophageal tissue.

RESUMO: A Pitiose é uma doença causada por oomicetos aquáticos do gênero Pythium. Em cães o curso típico da doença envolve o trato gastrointestinal, caracterizado por espessamento transmural do estômago ou intestinos. No entanto, a infecção por Pythium spp. raramente foi reconhecida como causa de esofagite em caninos. Assim, o presente trabalho tem como objetivo relatar um caso de pitiose esofágica e gástrica em um canino Pit Bull fêmea de oito meses de idade. O cão foi recebido no hospital com histórico de regurgitação e dispneia durante dois meses. Foi relatado que o animal era de um domicílio de área urbana e não possuía histórico pregresso de enfermidades. No exame clínico contatou-se ainda crepitações à ausculta pulmonar. Foi instituído tratamento de suporte e antibioticoterapia, porém após 22 dias de internação, o cão evoluiu para o óbito. Na necropsia, as paredes do segmento distal do esôfago e o cárdia e parte do fundo do estômago estavam expandidos por uma massa anular intramural focalmente extensiva e irregular. Além disso, havia uma fístula esofágica transmural. À histologia, as paredes do esôfago e do estômago apresentavam-se difusamente expandidas por áreas multifocais extensas de necrose, associadas a infiltrado piogranulomatoso, abundante proliferação de fibroblastos imaturos, neovascularização e contendo múltiplas imagens negativas de hifas realçadas pela impregnação por prata (Grocott). Além disso, tanto a imuno-histoquímica como PCR para P. insidiosum foram positivas em amostras de esôfago embebidas em parafina.

Mn-doped ZnO nanocrystals with Mn content varying from 0 to 5 at% were successfully synthesized via a simple hydrothermal method. The structural, morphological, and optical properties of the as prepared nanostructures were investigated. The photocatalytic activities of these materials were evaluated by determining the extent of the degradation reaction yield of an organic dye, methyl orange (MO) in an aqueous solution under UV light irradiation. The photodegradation efficiency of MO reached 91% in 180 min for pure ZnO, while all Mn- doped samples showed lower photocatalytic activity according to the following sequence: Zn095Mn005O < Zn099Mn001O < Zn097Mn003O < ZnO. Photocurrent measurements showed that the photocurrent density of ZnO was higher to that of Zn0.97Mn0.03O. In addition, impedance spectroscopy was used to investigate the electrical properties of ZnO and Zn097Mn003O at different temperatures (373-773 K) and various frequencies (10 Hz-13 MHz). The photocurrent density measurements and the explored electrical properties of ZnO and Zn097Mn003O revealed good accordance with the reduced photocatalytic activity of Zn097Mn003O nanocrystals.

BACKGROUND: Irrational medicine use is a global problem that may potentiate antimicrobial resistance AIM: This study aims to assess prescribing practices and the effect of a prescription audit and feedback coupled with small-group education intervention on prescribing indicators SETTING: The study was conducted in public-sector healthcare facilities in Eswatini METHODS: A cluster quasi-randomised controlled study was conducted from 2016 to 2019 using the World Health Organization/ International Network for Rational Use of Drugs (WHO/INRUD) prescribing indicators at baseline, post-intervention and post-follow-up. A 6-month unblinded intervention was tested in 32 healthcare facilities, randomly allocated to intervention (16) and control (16) arms. Prescribing practices were assessed post-intervention, and 6 months after the intervention, through an audit of 100 randomly selected prescriptions from each facility. Comparisons of WHO or INRUD prescribing indicators were conducted using the intention-to-treat analysis at the two times RESULTS: At baseline, in both arms, rational prescribing standards were met by the number of medicines per prescription and the use of injections. Antibiotic use was above 50% in both arms. After adjustment for baseline antibiotics use, region and level of care, there were no significant differences in all prescribing indicators between the two arms, post-intervention and at 6 months follow-up CONCLUSION: In a lower middle-income setting with a high prevalence of irrational prescribing practices, a prescription audit, feedback and small-group education intervention had no benefits in improving rational prescribing CONTRIBUTION: Multifaceted strategies, strengthening of pharmacy and therapeutics committees, and holistic monitoring of medicine use are recommended to promote rational medicine use

In this article, we review the monitoring and evaluation system that is used to measure the performance of primary healthcare delivered through the district health system and district management teams. We then review some global frameworks, especially linked to the World Health Organization, and look at some of the differences between what is internationally recommended and what we do in South Africa. We end with some recommendations to improve the system.

Abstract This study aimed to assess the impact of the implementation of a rapid multiplex molecular FilmArray Respiratory Panel (FRP) on the medical management of immunocompromised patients from a community general hospital. We conducted a single-center, retrospective, and before-after study. Two periods were evaluated: before the implementation of the FRP (pre-FRP) from April 2017 to May 2018 and after the implementation of the FRP (post-FRP) from January to July 2019. The inclusion criteria were immunocompromised patients over 18 years of age with suspected acute respiratory illness tested by conventional diagnostic meth-ods (pre-FRP) or the FilmArray™ Respiratory Panel v1.7 (post-FRP). A total of 142 patients were included, 64 patients in the pre-FRP and 78 patients in the post-FRP. The positive detec-tion rate was significantly higher in the post-FRP (63% vs. 10%, p <0.01). There were more patients receiving antimicrobial treatment in the pre-FRP compared with the post-FRP period (94% vs. 68%, p <0.01). A decrease in beta-lactam (89% vs. 61%, p <0.01) and macrolide (44% vs. 13%, p < 0.01) prescriptions were observed in the post-FRP. No differences were observed in oseltamivir use (22% vs. 13%, p = 0.14), changes in antimicrobial treatment, hospital admission rate, days-reduction in droplet isolation precautions, hospital length of stay (LOS), admission to intensive care unit (ICU), LOS in ICU, treatment failure and 30-day mortality. The implementa-tion of the FRP impacted patient care by improving diagnostic yield and optimizing antimicrobial treatment in immunocompromised adult patients.

Resumen El objetivo de este estudio fue evaluar el impacto de la implementación del panel respiratorio FilmArray® (FRP), un sistema automatizado de PCR multiplex, en el estándar de cuidado de pacientes adultos inmunocomprometidos en un hospital general. Es un estudio retrospectivo de un único centro con diseno antes/después. Los periodos evaluados fueron abril 2017-mayo 2018, previo a la implementación del FRP (pre-FRP), y enero 2019-julio 2019, luego de la implementación (post-FRP). Los criterios de inclusión fueron pacientes mayores de 18 años inmunocomprometidos con sospecha de infección respiratoria aguda a los que se les realizó, en pre-FRP, diagnóstico por métodos convencionales, y en post-FRP, el panel respiratorio FRP versión 1.7. Se incluyeron un total de 142 pacientes, 64 en pre-FRP y 78 en post-FRP. La tasa de positividad fue significativamente mayor en post-FRP frente a pre-FRP (63 vs. 10%, p<0,01). Hubo más pacientes con tratamiento antimicrobiano en pre-FRP que en post-FRP (94 vs. 68%, p <0,01). En pre-FRP hubo más pacientes tratados con betalactámicos (89 vs. 61%, p <0,01) y macrólidos (44 vs. 13%, p < 0,01). No se observaron diferencias significativas en el uso de oseltamivir (22 vs. 13%, p = 0,14), cambios en los tratamientos, número de hospitalizaciones, uso de aislamientos, duración de la estadía hospitalaria, ingreso a la unidad de cuidados intensivos, estadía en dicha unidad, falla de tratamiento y mortalidad a 30 días. El uso de FRP contribuyó a la atención del paciente mejorando el rendimiento diagnóstico y optimizando la terapia antimicrobiana en pacientes adultos inmunocomprometidos.

ABSTRACT The article aims to investigate Gilberto Freyre’s ecological and environmental discourses in two distinct but interrelated historical moments. In the first moment, this work analyzes newspaper articles published by the Diário de Pernambuco in the 1920s, particularly in 1924, when the young Freyre wrote a series of texts in defense of the arborization of Recife. The second moment, in the 1930s, was marked by the publication of Nordeste, book from 1937, in which the sociologist from Pernambuco criticized the environmental devastation of the Coastal Strip and the sugar mill complex. Freyre approached ecological questions within the intellectual and political architecture that characterized his work, intertwined with the defense of the tropics and Iberian traditions.

RESUMEN Este artículo tuvo por objetivo investigar los discursos ecológicos y ambientales de Gilberto Freyre en dos momentos históricos distintos, pero relacionados. En el primer momento, se analizan sus artículos periodísticos publicados en el Diário de Pernambuco durante la década de 1920, con énfasis en el año 1924, cuando el joven Freyre escribió una serie de textos en defensa de la arborización de la ciudad de Recife. En el segundo momento, en los años 1930, destaca la publicación Nordeste, libro de 1937 en el cual el sociólogo pernambucano criticó la devastación ambiental de la zona del monte y el complejo industrial de ingenios azucareros. Freyre abordó las temáticas ecológicas en el marco de la arquitectura intelectual y política de su obra, que se caracteriza por la defensa del trópico y de las tradiciones ibéricas.
