Resultados. Los pacientes presentaron una media de edad de 49,4 ± 19,6 años y el 53 % fueron hombres. El 86 % de los pacientes presentaron ruidos intestinales antes de 24 horas posteriores a la operación. La primera evacuación en los pacientes que ingirieron café tipo espresso fue a las 42,6 horas y para aquellos en el grupo de café americano fue a las 43,4 horas en comparación con 89,4 horas en el grupo control (p < 0,001). Conclusión. Se recomienda el uso del café como una medida segura y económica para el inicio de la dieta, como una alternativa al esquema tradicional, constituyéndose en una opción para el manejo del íleo postoperatorio

Introduction. Etymologically the word ileus comes from the Greek eileos, which means rolling or turning. It is described as the temporary delay of gastrointestinal motility. It is recognized worldwide that postoperative ileus is one of the main complications after surgery and represents an important problem due to its high healthcare cost. Research has been done regarding the preventive use of physical and pharmacological measures, such as prokinetics, for the management of postoperative ileus.Methods. Clinical-therapeutic, comparative, prospective longitudinal follow-up research, with non-probabilistic convenience sampling, made up of four groups with 25 patients each, treated in the General Surgery Service between May and August 2021. Results. The patients had a mean age of 49.4 ± 19.6 years and 53% were male; 86% of patients had bowel sounds within 24 hours after the operation. The first bowel movement in patients who ingested espresso coffee was 42.6 hours and for those in the American coffee group it was at 43.4 hours compared to 89.4 hours in the control group (p < 0.001). Conclusion. The use of coffee is recommended as a safe and economical measure to start the diet as an alternative to the traditional fashion, becoming an option for the management of postoperative ileus.

A oferta do café de rua nas capitais São Paulo e Vitória / The offer of coffee on the streets of the state capitals São Paulo and Vitória / La oferta de café en las calles de las capitales estatales São Paulo y Vitória

A pandemia gerou impactos sociais e econômicos, como o trabalho informal dos que se ocupam do serviço de café de rua, ampliado na retomada pós-isolamento. O artigo analisa as significações construídas pelas instalações do serviço nas ruas de São Paulo (SP) e Vitória (ES), enquanto manifestações do empreendedo-rismo por necessidade. O corpus foi coletado em dias úteis, no início das manhãs, em diversos pontos das capitais. A semiótica discursiva sustentou a análise, e o seu método permitiu traçar isotopias conectoras de figuras e temas. Os resultados apontam para comunicação dos sentidos da informalidade, casualidade e familiaridade, marcados pela presença feminina, pela autonomia imposta aos sujeitos produtor/vendedor e consumidor e pela conexão entre a energia proporcionada pela bebida e o trabalho. Esses significadosvêm embebidos no risco vivido por esses sujeitos, aconchegados entre si e alijados da proteção de políticas públicas de trabalho, condições sanitárias, serviços de transporte e saúde.

The pandemic has generated social and economic impacts, such as the informal work of those who sell coffee on the streets, expanded in the post-isolation resumption. The article analyzes the meanings constructed by the service facilities in São Paulo (SP) and Vitória (ES), as demonstrations of the entrepreneurship by necessity. The corpus was collected on weekdays, in places of the state capitals. Discursive semiotics underpins the analysis, suggesting connective isotopies of figures and themes. The results point to the communication of the senses of informality, casualness and familiarity, marked by the female presence, by the autonomy imposed on the subjects producer/seller and consumer and by the connection between the energy given by the drink and the work. These meanings are embedded in the risk experienced by these subjects, snuggled among themselves and excluded from the protection of public policies of work, sanitary conditions, transportation and health services.

Identification of microorganisms in wet coffee fermentation Coffea arabica Var Catimor and Castillo in Jardín, Antioquia-Colombia, using culture-dependent methods / Identificación de microorganismos en fermentación húmeda de café Coffea arabica Var Catimor y Castillo en Jardín, Antioquia-Colombia, usando métodos cultivo-dependientes

Background: Mild Colombian coffees are recognized worldwide for their high-quality coffee cup. However, there have been some failures in post-harvest practices, such as coffee grain fermentation. These failures could occasionally lead to defects and inconsistencies in quality products and economic losses for coffee farmers. In Colombia, one of the fermentation methods most used by coffee growers is wet fermentation, conducted by submerging the de-pulped coffee beans for enough time in water tanks to remove the mucilage. Objectives: We evaluated the effect of the water (g)/de-pulped coffee (g) ratio (I: 0/25, II: 10/25, III: 20/25) and final fermentation time (24, 48, and 72 hours) on the total number of microbial groups. We also identified microorganisms of interest as starter cultures. Methods: We used a completely randomized experimental design with two factors; the effect of the water (g)/de-pulped coffee (g) ratio (I: 0/25, II: 10/25, III: 20/25) and final fermentation time (24, 48, and 72 hours), for 9 treatments with two replicates. During the coffee fermentation (1,950 g), the pH and °Brix were monitored. Total counts of different microbial groups (mesophiles, coliforms, lactic-acid bacteria, acetic-acid bacteria, and yeasts) were performed. Various isolates of microorganisms of interest as starter cultures (lactic-acid bacteria and yeasts) were identified using molecular sequencing techniques. Results: 21 lactic-acid bacteria (LAB) isolates and 22 yeasts were obtained from the different mini-batch fermentation systems. The most abundant lactic-acid bacteria species found were Lactiplantibacillus plantarum (46%) and Levilactobacillus brevis (31%). Pichia kluivery (39%) and Torulaspora delbrueckii (22%) were the most abundant yeast species. Conclusion The studied factors did not have effect over the microorganism's development. The identified bacterial and yeasts species have potential as starter cultures for better-quality coffees and in fermentation-related applications.

Antecedentes: Los cafés suaves lavados colombianos son reconocidos a nivel mundial por su buena puntuación sensorial; sin embargo, se han detectado fallas en las prácticas de postcosecha, como lo es la fermentación de los granos de café. Dichas fallas pueden causar defectos y carecer de consistencia en la calidad del producto, ocasionando pérdidas económicas para los caficultores. En Colombia, uno de los métodos más usados por los caficultores es la fermentación húmeda, la cual consiste en sumergir los granos de café despulpado en tanques con agua por un período de tiempo que permita la remoción del mucílago. Objetivos: La presente investigación evaluó la incidencia que tienen la proporción agua/granos despulpados de café (I: 0/25, II: 10/25, III: 20/25) y el tiempo final de fermentación (24, 48 y 72 horas) en el recuento final de grupos microbianos. Por otra parte, se identificaron taxonómicamente microorganismos de interés para su uso como cultivos iniciadores. Métodos: Mini-lotes consistieron en café despulpado (1950 g) puesto en recipientes de plástico abiertos y sumergidos en agua. Se aplicó un diseño experimental completamente aleatorizado de dos factores (proporción agua/ granos de café despulpado y tiempo) a tres niveles, para un total de nueve tratamientos con dos replicas. Durante las fermentaciones de café (1,950 g), el pH y los grados ºBrix, fueron monitoreados. Se realizaron los recuentos totales de los diferentes grupos microbianos: mesófilos, coliformes, bacterias ácido-lácticas, bacterias ácido-acéticas y levaduras. Se identificaron molecularmente diferentes aislados con potencial para ser usados como cultivos iniciadores (bacterias ácido-lácticas y levaduras). Resultados: Los resultados obtenidos mostraron que no hubo diferencia estádisticamente significativa entre los tratamientos aplicados y el recuento final de microorganismos. Un total de 21 aislados de bacterias ácido-lácticas (BAL) y 22 levaduras lograron obtenerse a partir de los diferentes sistemas de fermentación en mini-lote. Las especies de bacterias ácido-lácticas con mayor porcentaje acorde a su identificación taxonómica, corresponden a Lactiplantibacillus plantarum (46%), Levilactobacillus brevis (31%). Las especies de levaduras con mayor porcentaje acorde a su identificación taxonómica corresponden a Pichia kluivery (39%) y Torulaspora delbrueckii (22%). Conclusión Los factores estudiados no afectaron el crecimiento de ninguno de los grupos microbianos presentes en la fermentacion del café. Las especies de microorganismos identificados tienen potencial para se usados como cultivos starter o en aplicaciones dentro de las ciencias de fermentación.

A knowledge, attitude and practices based study to know the awareness and acceptance of contraceptive methods in married couples coming to well-baby clinic of a tertiary care centre in Panvel, Maharashtra, India

Background: Family planning plays a major role in improving the financial, nutritional, educational, social well-being of a family as a unit. To study the level of knowledge, attitude and practices of various family planning methods in eligible couples. Methods: Prospective Qualitative study was carried out from June 2021 - December 2022 on data of 180 eligible couples selected randomly from Well-Baby Clinic, collected through pretested and validated standardized questionnaire. Sample size was estimated scientifically. Results were arrived by descriptive statistical tests and correlational statistics using software’s like excel, SPSS. Results: The level of knowledge of contraceptive methods was 89.44% for OC pills, 67.08% depot medroxyprogesterone, 97.22% condoms, 84.03%, IUCD, 93.56% for female and 98.04% for male sterilization. Overall acceptance of any type of contraception was 55%, most commonly used method being condoms i.e.78.49%, OC pills 12.90%, IUCD 6.35%, depot 1.37% and 45% were using natural methods. Major factors affecting acceptance were desire to have more children, hesitancy to seek, lack of knowledge, decision making power of a woman in the family. Conclusions: Since our research finds contraceptive acceptance at 55% much lower than state average, we look into components of gender dynamics and offer array of choices to couples so that a well informed choice free of gender bias is taken. Continuity of personalized and dignified couple counseling from preconceptional, antenatal to postnatal period is emphasized to increase contraceptive acceptance. We recommend well baby clinics as effective point of delivery for family welfare activities using gender sensitive cafe-teria approach.

RESUMEN La displasia fibrosa es una enfermedad ósea benigna y progresiva, de base genética que puede afectar a uno o varios huesos. Su alta incidencia en la edad pediátrica sirvió de base para que anteriormente fuera considerada exclusiva de esta etapa; sin embargo, a la fecha, existen reportes que evidencian su desarrollo y crecimiento posterior en la segunda década de vida. Cuando está asociada a desequilibrios endocrinos y manchas café con leche, forma parte del síndrome de McCune-Albright. El presente reporte de caso muestra las características clínicas y radiológicas de la región bucofacial de un paciente adulto portador del síndrome de McCune-Albright. Las lesiones en los maxilares afectan la morfología y causan disfunción. A nivel dentario, los cambios producidos se traducen en maloclusión y defectos estructurales. En los estudios radiológicos se observaron cambios con densidad mixta y el patrón de vidrio esmerilado.

ABSTRACT Fibrous dysplasia is a benign and progressive bone disease of genetic basis that can affect one or several bones. Its high incidence in the pediatric age served as a basis for it to be previously considered exclusive to this stage; however, there are reports to date that show its development and later growth in the second decade of life. When associated with endocrine imbalances and café-au-lait spots, it is part of the McCune-Albright syndrome. The present case report shows the clinical and radiologic features of the oral-facial region of an adult patient with McCune-Albright syndrome. Lesions in the jaws affect the morphology and cause dysfunction. At the dental level, the changes produced result in malocclusion and structural defects. Radiological studies showed changes with mixed density and ground glass pattern.

RESUMO A displasia fibrosa é uma doença óssea benigna, progressiva e de base genética que pode afetar um ou mais ossos. A sua elevada incidência no grupo etário pediátrico foi a base para que anteriormente fosse considerada exclusiva desta fase; no entanto, existem relatos até à data do seu desenvolvimento e crescimento mais tardio na segunda década de vida. Quando associada a desequilíbrios endócrinos e manchas café-com-leite, faz parte da síndrome de McCune-Albright. Este relato de caso mostra as características clínicas e radiológicas da região bucofacial de um paciente adulto com síndrome de McCune-Albright. As lesões nos maxilares afetam a morfologia e provocam disfunções. A nível dentário, as alterações produzidas resultam em má oclusão e defeitos estruturais.

olf413 Gene Controls Taste Recognition, Preference and Feeding Activity in Drosophila melanogaster

Recognition and responsiveness to food taste becomes a crucial event in foraging and feeding behaviour of an organism. Adjusting the feeding behaviour through a sophisticated and robust taste system is critical to fulfil their nutritional needs and facilitate its survival in environment. Palatability of food sources depends on the sensory and motor cues provided by the brain, in co-ordination with the other body systems to enable decisive feeding. Drosophila melanogaster is an apt model organism to decipher these behavioural paradigms. Octopamine a neurotransmitter, is required in regulation of feeding behavioural responses. olf413, a paralogue of TH, is a gene predicted for its involvement in octopamine biosynthesis. The biological function of this gene is yet to be unravelled. Here we propose this gene function in taste recognition, food preference and feeding activity. We test the olf413 loss of function mutants for food preference between two fruit extracts using CAFE and horizontal box methods. In our study we have used olf413 gene disruption strain, olf413MI02014 homozygous and in transheterozygous condition with another allele isolated in our lab, olf413SG1.1. The results show that olf413 mutants display a severe phenotype in feeding behaviour and there is an allele specific phenotypic distinction between the two strains. Thus implying that olf413 gene function is required for taste recognition, starvation driven initiation and execution of feeding behaviour of the flies.

Mc Cune Albright syndrome: gynecological perspective

The key features of McCune-Albright syndrome include sexual precocious puberty, polyostotic fibrous dysplasia and café au lait spots. It is associated with hyperfunction of multiple endocrine glands. Other endocrine dysfunctions often associated are growth hormone excess, hyperthyroidism, Cushing’s syndrome, hyperprolactinemia and phosphate wasting. We had a case of McCune-Albright syndrome with precocious puberty and irregular cycles and was managed. It is a rare cause of precocious puberty and should be kept in mind while dealing with such cases.

Improvement of Health Awareness among Pharmacy Students through Holding a Women's Health Care Cafe / 日本プライマリ・ケア連合学会誌

In Japan, there are insufficient measures to ensure that women can maintain good health while working. In addition, many women have limited health literacy, making it difficult for them to access information on physical and mental health problems that are specific to them. In this context, it is essential for pharmacists to become the first point of contact for women seeking information about their physical health, as they are familiar with healthcare providers in the community. To address this issue, we organized a Women's Health Care Cafe for pharmacy students to provide them with an opportunity to learn about women's health.

Efeitos da cafeína no organismo humano / Effects of caffeine on the human body / Efectos de la cafeina en el cuerpo humano

A cafeína é uma substância presente em diversas bebidas e suplementos, que sua forma mais comum de ingestão é através do café. Devido a ampla procura pela substância e sua larga distribuição mundial, este trabalho apresenta uma revisão de literatura sobre a cafeína e seus efeitos no organismo humano. Ao longo do tempo, a cafeína teve seu consumo aumentado em diversas faixas etárias, além de estar presente em diferentes produtos. A ingestão da cafeína pode estimular a concentração e melhorar o desempenho físico, devido ao seu efeito estimulante do sistema nervoso central. O uso em suplementos está envolvido nos seus efeitos termogênicos, auxiliando no processo de lipólise e melhorando o rendimento nas atividades físicas. O consumo da cafeína é associado ainda com a redução do LDL-colesterol, porém, os efeitos sobre o colesterol plasmático ainda são controversos. Todavia, o uso excessivo da cafeína pode trazer malefícios ao sistema cardiovascular como a diminuição da frequência e pressão cardíaca, dilatação de vasos e redução da temperatura corporal. A sua ingestão quando associada a bebidas alcoólicas pode ocultar a sensação depressiva do álcool, podendo elevar as chances de intoxicação. Na gestação aconselha-se o uso limitado, pois não há estudos conclusivos sobre os efeitos da cafeína para o feto. A relação risco e benefício deve sempre ser avaliada de acordo com cada indivíduo, sendo o aconselhamento e acompanhamento do consumo da cafeína realizado por um profissional de saúde habilitado, como o farmacêutico, para assim se reduzir possíveis prejuízos que a cafeína pode trazer à saúde.

Caffeine is a substance present in several drinks and supplements, which its most common form of intake is through coffee. Due to the broad demand for the substance and its wide distribution worldwide, this work presents a literature review on caffeine and its effects on the human organism. Over time, caffeine has increased its consumption in several age groups, in addition to being present in different products. The intake of caffeine can stimulate concentration and improve physical performance, due to its central nervous system stimulating effect. The use in supplements is involved in its thermogenic effects, assisting in the process of lipolysis and improving the performance in physical activities. The consumption of caffeine is also associated with the reduction of LDL-cholesterol, but the effects on plasma cholesterol are still controversial. However, excessive use of caffeine can cause harm to the cardiovascular system, such as decreased heart rate and pressure, vessel dilation, and reduced body temperature. Ingestion of alcohol in association with alcohol may mask the depressive sensation of alcohol and may increase the chances of intoxication. In pregnancy, limited use is advised, as there are no conclusive studies on the effects of caffeine on the fetus. The risk-benefit ratio should always be evaluated according to each individual, and the advice and follow-up of caffeine consumption is carried out by a qualified health care professional, such as the pharmacist, in order to reduce possible damage that caffeine can bring to health.

Sin embargo, el uso excesivo de cafeína puede dañar el sistema cardiovascular, como una reducción de la frecuencia y la presión cardiaca, la dilatación de los vasos y una reducción de la temperatura corporal. La deglución combinada con alcohol puede enmascarar la sensación deprimida de alcohol y puede aumentar la posibilidad de intoxicación. En el embarazo se aconseja un uso limitado, ya que no hay estudios concluyentes sobre los efectos de la cafeína sobre el feto. La relación riesgo-beneficio debe evaluarse siempre de acuerdo con cada individuo, con el asesoramiento y el control del consumo de cafeína por parte de un profesional sanitario autorizado, como el farmacéutico, a fin de reducir el posible daño que la cafeína puede causar a la salud.

Skipping breakfast associated with socioeconomic and lifestyle factors in Brazilian adolescents / Omitir o café da manhã está associado a fatores socioeconômicos e de estilo de vida entre adolescentes brasileiros

Abstract The aim is to estimate the prevalence and evaluate the association of socioeconomic and lifestyle factors with skipping breakfast among Brazilian adolescent students. A cross-sectional study carried out with adolescent ninth-graders from Brazilian public and private schools participating in the 2015 National School Health Survey. The prevalence of skipping breakfast (less than five days/week) and its respective 95% confidence intervals were estimated and stratified by gender according to demographic, socioeconomic, and lifestyle factors, self-perceived body image, and attitudes towards weight. A three-block hierarchical Poisson regression, considering the complex sample design. The prevalence of skipping breakfast was 35.6%, higher among girls than boys. In both genders, skipping breakfast was positively associated with the highest socioeconomic level, morning school shift, paid work, regular consumption of alcoholic beverages, living only with the mother, the father or neither, the irregular consumption of school food and meals with parents, considering oneself too fat/fat and trying to lose weight. In general, skipping breakfast was associated with socioeconomic factors and lifestyle behaviors harmful to health among adolescent students.

Resumo O objetivo é estimar a prevalência e avaliar a associação dos fatores socioeconômicos e de estilo de vida com a omissão do café da manhã entre adolescentes escolares brasileiros. Um estudo transversal realizado com adolescentes do 9º ano de escolas públicas e privadas brasileiras participantes da Pesquisa Nacional de Saúde do Escolar de 2015. A prevalência de omissão do café da manhã (menos de cinco dias/semana) e seus respectivos intervalos de confiança de 95% foram estimados e estratificados por sexo de acordo com fatores demográficos, socioeconômicos, estilo de vida, autopercepção da imagem corporal e atitudes em relação ao peso. Uma regressão de Poisson hierárquica de três blocos, considerando o desenho amostral complexo. A prevalência de pular o café da manhã foi de 35,6%, maior entre as meninas do que entre os meninos. Em ambos os sexos, omitir o café da manhã associou-se positivamente com maior nível socioeconômico, turno escolar matutino, trabalho remunerado, consumo regular de bebidas alcoólicas, morar apenas com a mãe, pai ou nenhum dos dois, consumo irregular de alimentação escolar e refeições com os pais, considerar-se muito gordo/gordo e tentar perder peso. Em geral, a omissão do café da manhã foi associada a fatores socioeconômicos e comportamentos de estilo de vida prejudiciais à saúde entre estudantes adolescentes.

CARACTERIZACIÓN Y DISMINUCIÓN EN LA EXPRESIÓN DE UNA QUITINA SINTASA MEDIADA POR ARNi EN Hypothenemus hampei (CURCULIONIDAE) / Characterization and RNAi-mediated knockdown of a chitin synthase in Hypothenemus hampei (Curculionidae)

RESUMEN La broca del café, Hypothenemus hampei, es un insecto plaga que causa daños significativos al grano de café y grandes pérdidas económicas a los productores en todo el mundo. Al igual que otros insectos, la broca de café requiere de quitina sintasas (CHS) para la biosíntesis de la quitina, componente principal del exoesqueleto del insecto, y de vital importancia para su crecimiento y desarrollo. En este estudio, el gen CHS1 de la broca del café (HhCHS1) fue identificado, caracterizado y posteriormente silenciado mediante el uso de ARNi, mecanismo que permite degradar el ARNm e interrumpir la expresión de proteínas de interés en un organismo. Los perfiles de expresión del gen HhCHS1, medidos por RT-qPCR, mostraron niveles de expresión diferencial en las diferentes etapas del desarrollo del insecto. Los niveles más altos de expresión se encontraron en larvas de segundo estadio (L2) y machos adultos. El ARNcd administrado por vía oral, a concentraciones de 2 µg/100 µL, generó un silenciamiento efectivo del gen HhCHS1 (84 %) después de 7 días de tratamiento. Estos resultados sugieren que el gen HhCHS1 desempeña un papel importante en el desarrollo del insecto, y que, por ende, podría usarse como objetivo para desarrollar nuevas estrategias de manejo de este insecto plaga, mediante el uso de ARNi.

ABSTRACT The coffee berry borer, Hypothenemus hampei, is an insect pest that causes significant damage to the grain and profound economic losses to coffee crops and producers worldwide. Like other insects, the coffee berry borer requires chitin synthases (CHS) for the biosynthesis of chitin, which is the main component of the insect exoskeleton, as well as a component of vital importance for their growth and development. In this study, the coffee berry borer CHS1 gene (HhCHS1) was identified, characterized, and subsequently silenced by using RNAi, a mechanism that allows mRNA to be degraded, interrupting the expression of the proteins of interest in an organism. The expression profiles of the HhCHS1 gene, measured by RT-qPCR, showed levels of differential expression in the different stages of insect development. The highest levels of expression were found in second instar (L2) larvae and adult males. Orally administered dsRNA, at concentrations of 2 µg/100 µL, was able to generate effective HhCHS1 silencing (84 %) after 7 days of treatment. These results suggest that the HhCHS1 gene plays an important role in the development of the coffee berry borer that could be used as target to develop new management strategies of this insect pest by using RNAi.

Evaluación del desempeño de una celda de combustible microbiana con electrodo de grafito modificado para el tratamiento de agua residual del procesamiento del café / Evaluation of the performance of a microbial fuel cell with modified graphite electrode for the treatment of wastewater from coffee processing / Avaliação do desempenho de uma célula combustível microbial com eletrodo de grafite modificado para o tratamento de águas residuais do processamento de café

Resumen La actividad cafetalera en Costa Rica procesa aproximadamente 69.000 toneladas de café mediante la técnica de beneficiado húmedo. Esta actividad conlleva un alto impacto ambiental debido a la generación de8Lde agua residual/kg de café oro producido. El presente trabajo tiene como objetivo utilizar el agua residual del procesamiento de café como sustrato en celdas combustibles microbianas (CCM), con el propósito de generar energía eléctrica a través de su uso y, a la vez, disminuir la carga orgánica del residuo. La CCM empleó un cátodo modificado con ftalocianinas de hierro (FePc), generó una eficiencia coulómbica de 0,7% y una densidad de potencia de 89 UW/ cm2 en un ciclo de operación de cinco días. Además, se determinó que la CCM disminuye la demanda química de oxígeno (DQO) del residuo hasta en 27% bajo las condiciones de operación nativas del sustrato, a temperatura ambiente, sin mediadores químicos para la reacción anódica y con el uso de electrodos de platino para el cátodo. El estudio confirma la oportunidad de emplear el sustrato con una flora microbiana nativa apta para la operación de la tecnología de la CCM, y así perfilar el dispositivo como una opción novedosa para el tratamiento de este residuo en Costa Rica.

Abstract In Costa Rica coffee production is the most traditional agroindustrial activity, each year approximately 69,000 tons of coffee are processed through the technique of wet processing. The process has a high environmental impact since it generates eight liters of wastewater/kg of produced coffee. Consequently, the main goal of this research was to evaluate the electric generation of a Microbial Fuel Cell (MFC) with two chambers, using coffee wastewater as a substrate, which would generate a sustainable solution with an added economic value to this waste in Costa Rica. The MFC with a cathode modified with iron phthalocyanines (FePc) generated a coulombic efficiency of 0.7% and a power density of 89 -uW/cm2 in a 5-day operation cycle. In addition, it was determined that the MFC decreases the COD of the waste by up to 27% under native substrate conditions, without the use of high temperatures, or chemical mediators for the anodic reaction and platinum electrodes for the cathode chamber. The efficiency of the device can be improved with changes at design level that reduce the ohmic internal resistance and improve electrical generation, the study confirms the potential of the substrate with a native microorganism suitable for the use of MFC technology, shaping the device as a novelty option for the treatment of the waste in Costa Rica.

Resumo A indústria do café na Costa Rica processa cerca de 69 000 toneladas de café por meio da técnica de moagem úmida, o que acarreta um alto impacto ambiental devido à geração de 8 L de água residual / kg de café dourado. O objetivo deste trabalho era usar águas residuais do processamento do café como substrato em Células de Combustível Microbianas (CCM) a fim de gerar energia elétrica por meio do seu aproveitamento e ao mesmo tempo reduzir a carga orgânica do resíduo. CCM usando cátodo modificado com ftalocianinas de ferro (FePc) gerou uma eficiência coulômbica de 0,7% e uma densidade de potência de 89 uW/cm2 em um ciclo operacional de cinco dias. Além disso, foi determinado que o CCM reduz a Demanda Química de Oxigénio (DQO) do resíduo em até 27% nas condições nativas de operação do substrato, à temperatura ambiente, sem mediadores químicos para a reação anódica e com a utilização de eletrodos de platina para o cátodo. O estudo confirma a oportunidade de utilizar o substrato com flora microbiana nativa adequada para o funcionamento da tecnologia CCM e, assim, delinear o dispositivo como uma nova opção para o tratamento desses resíduos na Costa Rica.

Green coffee bean extract attenuates gentamicin induced acute nephrotoxicity in rats / El extracto de grano de café verde atenúa la nefrotoxicidad aguda inducida por gentamicina en ratas

Gentamicin induced acute nephrotoxicity (GIAN) is considered as one of the important causes of acute renal failure. In recent years' great effort has been focused on the introduction of herbal medicine as a novel therapeutic agent for prevention of GIAN. Hence, the current study was designed to investigate the effect of green coffee bean extract (GCBE) on GIAN in rats. Results of the present study showed that rat groups that received oral GCBE for 7 days after induction of GIAN(by a daily intraperitoneal injection of gentamicin for 7days), reported a significant improvement in renal functions tests when compared to the GIAN model groups. Moreover, there was significant amelioration in renal oxidative stress markers (renal malondialdehyde, renal superoxide dismutase) and renal histopathological changes in the GCBE-treated groups when compared to GIAN model group. These results indicate that GCBE has a potential role in ameliorating renal damage involved in GIAN.

La nefrotoxicidad aguda inducida por gentamicina (GIAN) se considera una de las causas importantes de insuficiencia renal aguda. En los últimos años, el gran esfuerzo se ha centrado en la introducción de la medicina herbal como un nuevo agente terapéutico para la prevención de GIAN. Por lo tanto, el estudio actual fue diseñado para investigar el efecto del extracto de grano de café verde (GCBE) sobre la GIAN en ratas. Los resultados del presente estudio mostraron que los grupos de ratas que recibieron GCBE oral durante 7 días después de la inducción de GIAN (mediante una inyección intraperitoneal diaria de gentamicina durante 7 días), informaron una mejora significativa en las pruebas de función renal en comparación con los grupos del modelo GIAN. Además, hubo una mejora significativa en los marcadores de estrés oxidativo renal (malondialdehído renal, superóxido dismutasa renal) y cambios histopatológicos renales en los grupos tratados con GCBE en comparación con el grupo del modelo GIAN. Estos resultados indican que GCBE tiene un papel potencial en la mejora del daño renal involucrado en GIAN.

McCune-Albright syndrome - A case report with transmission electron microscopy

Abstract McCune - Albright syndrome is a genetic disease with cutaneous mosaicism caused by post-zygotic activating mutations in GNAS locus, it has a triad of fibrous bone dysplasia, café-au-lait macules and precocious puberty. We examined a 22-year-old female patient with café au lait spot in right side of the abdomen, with a chessboard - like distribution, extending to right thigh with geographical contours, she has also an ovarian cyst, scoliosis and truncal obesity. Biopsies were taken from the hyperpigmented area and processed for light microscopy and for transmission electron microscopy. Light microscopy showed increased melanin pigment with HE staining. Immunohistochemistry with melanocytic markers (HMB-45 and Melan-A) revealed a normal number of melanocytes. Transmission electron microscopy demonstrated normal epidermal structures, such as desmosomes, cytokeratin filaments and hemidesmosomes. With high magnifications an irregular melanossomal contour was seen, with some indentations in their outline.

Analysis of clinical features in children with McCune-Albright syndrome / 中华实用儿科临床杂志

Objective:To summarize and analyze the clinical features of McCune-Albright syndrome (MAS) in 26 children, to improve the understanding of MAS diagnosis and treatment, and to achieve early clinical diagnosis of MAS.Methods:The clinical data of 26 children with MAS treated in Department of Pediatrics, Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology from August 2011 to June 2021 were retrospectively analyzed.Their clinical characteristics were summarized and studied. t-test, Mann- Whitney U test, χ 2 test or Fisher′ s exact probability method was used for comparison between groups. Results:(1) Among the 26 MAS patients enrolled, there were 22 females and 4 males.The average onset age of female and male patients was (5.87±2.94) years old and (7.48±3.36) years old, respectively.(2) In female patients, there were 7 cases with the typical triad and 15 cases with the atypical triad.(3) Female patients had the first symptom of vaginal bleeding (8/22) and breast development (14/22). Among the 4 male children, 1 case had " fracture" and 3 cases " lagged behind their peers in height" at the first visit.(4) Compared with the breast development group, the vaginal bleeding group had an earlier onset age[(4.06±1.88) years old vs.(7.82±1.82) years old] ( t=5.023, P<0.001), earlier bone maturation[(1.26±0.07) vs.(1.09±0.13)] ( t=2.933, P<0.05), a greatly lowered predicted adult height[(-2.16±0.98) SDS vs.(-0.96±1.09) SDS]( t=1.352, P<0.05), a lower blood phosphorus level[(1.41±0.14) nmol/L vs.(1.67±0.24) nmol/L] ( t=1.941, P<0.05), and a significantly elevated alkaline phosphatase level[339(313, 656) U/L vs.243(205, 452) U/L] ( U=1.000, P<0.05). All patients (8 cases) in the vaginal bleeding group had fibrous dysplasia of bone.(5) Ten patients progressed to central precocious puberty (CPP). They showed an older average age of onset[(7.27±2.69)years old vs.(4.69±2.68)years old] ( U=44.000, P<0.05), significantly earlier bone maturation at diagnosis[(1.23±0.11) vs.(1.01±0.13)] ( t=1.834, P<0.05), and a lower predicted adult height[(152.00±4.62) cm vs.(162.10±6.91) cm] ( t=3.805, P<0.05), compared with those who did not progress to CPP.(6) Eleven children developed polyostotic fibrous dysplasia of bone, and most common type (8 cases) was polyostotic fibrous dysplasia of bone, primarily at lower limb bones and skulls.(7) Of the 26 children, 20 cases had scattered Café au lait pigments on the skin.The Café au lait pigmented skin lesions in 35% (7/20) cases crossed the midline. Conclusions:With complicated clinical manifestations, MAS is more common and occurs earlier in girls than boys.It is difficult to clinically diagnose MAS in boys due to the insidious onset and atypical symptoms.Female MAS patients with vaginal bleeding as the first symptom usually have an early age of onset, advanced bone age and lower predicted adult height, so they should be monitored and evaluated clinically.Vaginal bleeding is significantly associated with polyostotic fiber dysplasia of bone in MAS patients.Therefore, it is recommended that patients with vaginal bleeding should undergo a routine bone single-photon emission computed tomography scan.This helps understand the situation of occult fiber dysplasia of bone.Patients with later diagnosis and advanced bone age should be aware of the possibility of progression to CPP.

Researching with older people: an experience in participative mapping and world café techniques / Pesquisando com pessoas idosas: uma experiência com as técnicas de mapeamento participativo e world café / Investigar con personas mayores: una experiencia en tecnicas de mapeo participativo y world café

The multidimensionality of the aging process involves changes in different capacities. The age-friendly cities strategy addressed the need for adaptations in urban spaces that meets the demands of older people's well-being. Thus, the aim of this study was to explore how Participative Mapping and World Café techniques could assist in identifying challenges to the delivery of services and resources to create communities that promote active aging, from the perspectives of older people and stakeholders. The techniques generated co-constructed discussion and shared understandings about the barriers residents face in negotiating and accessing services. Demands associated with the precariousness of local infrastructure, the absence of leisure activities, and a generalized feeling of insecurity in their neighborhoods were recurring themes. The demands led to the conclusion that for healthy aging, the interrelation of objective and subjective factors that take into account the multidimensionality of old age will enable the active participation.

El consumo de café: su asociación con el riesgo de padecer cáncer / Coffee consumption: its association with the risk of cancer

RESUMEN El café y su impacto en la salud es un tema en el que resulta válido profundizar. Históricamente, el consumo de café se ha asociado con efectos adversos, como problemas cardiovasculares y varios tipos de cáncer. Pero en gran cantidad de fuentes bibliográficas contemporáneas se enfatiza en los efectos beneficiosos de su consumo, sin mencionar los daños que puede ocasionar a la salud. Se hace esta revisión bibliográfica con el objetivo de profundizar en lo más actualizado sobre los beneficios y perjuicios del consumo del café y su relación con la aparición del cáncer. En la revisión se consultaron artículos de las bases de datos PubMed, SciELO, ClinicalKey y LILACS. Se constató que el consumo de café no se asocia con la aparición de diferentes tipos de cánceres, y que el consumo moderado aporta propiedades protectoras para la salud. Teniendo en cuenta el carácter multifactorial del cáncer, los autores consideran que suponer que el consumo de esta bebida puede impedir carcinogénesis, es una tesis que debe ser interpretada con cautela (AU).

ABSTRACT Coffee and its impact on health is a topic on which it is valid to deepen. Historically, coffee consumption has been associated with side effects, such as cardiovascular problems and several types of cancer. But many contemporary bibliographic sources emphasize the beneficial effects of its consumption, without mentioning the damage it can cause to health. This bibliographic review is done with the aim of deepening into the most updated knowledge about the benefits and harms of coffee consumption and its relationship with the appearance of cancer. Articles from PubMed, SciELO, ClinicalKey and LILACS databases were reviewed. It was found that coffee consumption is not associated with the appearance of different types of cancers, and that moderate consumption provides protective properties for health. In view of the multifactorial character of cancer, the authors consider that assuming that the consumption of this drink can prevent carcinogenesis is a thesis that should be taken with caution (AU).

Obtención de bioproductos a partir de residuos del beneficio húmedo del café (pulpa) / Obtaining Bioproducts from Residues of the Wet Benefit of Coffee (Pulp)

RESUMEN Este trabajo presenta los resultados obtenidos a escala de laboratorio para el aprovechamiento de la pulpa de café (residuos) en el proceso de beneficio húmedo aplicando el concepto de biorrefinería. Los resultados mostraron que es posible tratar este residuo mediante procesos fermentativos y obtener bioetanol separado por medio de la destilación simple con un contenido de alcohol entre 3,85 % al 6,90 % por cada 250 ml de biomasa tratada en condiciones ambientales. Se observó en todos los ensayos que una variable importante es el tiempo de fermentación y la estructura inicial del residuo ya que esto influye sobre el rendimiento obtenido en términos del bioalcohol producido. Este trabajo forma parte de un estudio preliminar para la implementación del concepto de biorrefinería a los residuos generados en el beneficio húmedo del café. La búsqueda de alternativas que permitan el aprovechamiento de los residuos del café constituye una problemática actual. Estos residuos al no ser tratados, por lo general son vertidos a las fuentes hídricas y en ocasiones utilizados como enmiendas agrícolas en los cultivos, lo cual puede causar graves problemas de contaminación. Por este motivo es necesario realizar investigaciones en este campo que permitan su tratamiento o aprovechamiento integral.

ABSTRACT This work presents the results obtained at a laboratory scale for the use of coffee pulp (residues) in the wet milling process applying the concept of biorefinery. The results showed that it is possible to treat this residue through fermentative processes and obtain bioethanol through simple distillation with an alcohol content between 3.85% to 6.90% for each 250ml of biomass with a solid-liquid ratio of 4 to 1 to environmental conditions. It was observed in all the tests that the fermentation time and the initial structure of the residue are important variables since they influence the yield obtained in terms of produced alcohol. This work is part of a preliminary study for the implementation of the biorefinery concept to the residues generated in the wet coffee mill. The search of alternatives that allow the use of coffee residues is a current problem. These residues, when not treated, are generally dumped into water sources and sometimes used as agricultural amendments in crops, which can cause serious contamination problems. For this reason, it is necessary to carry out research in this field for its treatment or comprehensive use.
