Determination of Polyphenolic Profile of Apple Pomace (Malus domestica Golden Delicious Variety) by HPLC-MS.

Apple (Malus domestica Borkh) is an appreciated source of polyphenols. Phenolic compounds are known as natural antioxidants and have a wide range of applications in different industries. Apple pomace has the potential of being an alternative source of polyphenols. To determine the polyphenolic profile of apple pomace, samples from the skin at two different stages of ripening were extracted with 80-20% EtOH-water/acetic acid 5% (S1) and 20-80% EtOH-water/acetic acid 5% (S2) in order to determine the solvent system. Ripe skins extracted with S1 showed a higher total polyphenol content or TPC (1.21 g of polyphenols per 100 g of fresh weight (FW)) than unripe apple skin, being the most effective system tested and a mean degree of polymerization of 2.47. Commercial apple pomace was extracted with S1, resulting in a TPC of 0.5615 ± 0.007 g of polyphenols per 100 g of FW. Meanwhile, the RP-HPLC-MS analysis led to the tentative identification of several polyphenolic compounds.

Pyeloureteral Anastomosis as a Reconstructive Technique for Post-Renal Transplant Ureteral Stenosis.

OBJECTIVE: Ureteral stenosis in renal transplant patients is a frequent urological complication that involves significant morbidity and may compromise graft function. Despite the common use of minimally invasive techniques, surgery continues to be the definitive treatment for ureteral stenosis, and pyeloureteral anastomosis is an infrequent but effective technique in the management of this pathology and has been described as a safe treatment with a low percentage of complications. METHODS: This is a retrospective study of patients in whom surgical intervention via pyeloureteral anastomosis was carried out in our center in the last 12 years. A descriptive analysis of perioperative management, complications, and functional results is provided. A comparison of renal function at diagnosis and after surgery was made to evaluate the effectiveness of the procedure. RESULTS: Thirteen patients underwent surgery within the described time frame. Time to diagnosis of stenosis was 60 days [interquartile range (IQR) 31-368]. Creatinine at diagnosis was 2.2 mg/dL [IQR 1.9-3] with a glomerular filtration rate, estimated by the modification of diet in renal disease equation, of 29 mL/min/1.73 m2 [IQR 22.6-34.5]. Of these patients, 92.3% underwent percutaneous nephrostomy, and 38.5% also had a ureteral catheter. The mean duration of surgery was 265 minutes [IQR 240-300], and hospital stay was 9 days [IQR 7.5-16]. A double J was placed in all cases, which was maintained for 36 days [IQR 30-49]. Postoperative complications occurred in 15.4% of patients. Serum creatinine 1 year after surgery was 1.6 ± 0.4 mg/dL. Among the patients, 76.9% had no new pyelocalyceal dilatation on follow-up Doppler ultrasound scans at a mean follow-up time of 12 months. The restenosis rate was 23.1%, and all were successfully treated by endoscopic approach. There was an improvement in renal function figures at 1, 3, 6, and 12 months compared to renal function at diagnosis, both in terms of serum creatinine and glomerular filtration rate, with statistically significant results. CONCLUSION: Pyeloureteral anastomosis as a reconstructive technique of the urinary tract in renal transplant patients is an effective and reproducible technique with good long-term results.

The presence of depressive symptoms and cognitive performance among older individuals with and without self-reported chronic diseases.

Dementias secondary to cardiovascular diseases are the second cause of neurogenerative diseases. These conditions can be prevented by controlling risk factors, and it is necessary to observe the relationship between chronic diseases. Objective: to know the influence of chronic non-communicable diseases on cognition and depressive symptoms in the elderly, amid the COVID-19 pandemic. Methods: 578 older adults were evaluated using a sociodemographic questionnaire, the Brazilian Telephone version of the Mini Mental State Examination (Braztel-MMSE), the Geriatric Depression Scale (GDS-15) and an open questionnaire related to NCDs.

Subjective impacts of computerized cognitive training for healthy older adults in the context of the COVID-19 pandemic.

BACKGROUND: Computerized cognitive training programs may have benefited the self-assessment of memory, quality of life, and mood among older adults during the coronavirus disease 2019 (COVID-19) pandemic. OBJECTIVE: To determine the subjective impacts of computerized cognitive training on mood, frequency of forgetfulness, memory complaints, and quality of life in the elderly using an online platform. METHODS: In total, 66 elderly participants of USP 60 + , a program for the elderly offered by Universidade de São Paulo, who voluntarily enrolled in the study were selected and randomized with an allocation ratio of 1:1 into 2 groups: the training group (n = 33) and the control group (n = 33). After signing the free and informed consent form, they answered a protocol which included a sociodemographic questionnaire, the Memory Complaints Questionnaire (MAC-Q), the McNair and Kahn's Frequency of Forgetfulness Scale, the Geriatric Depression Scale (GDS-15), the Geriatric Anxiety Inventory (GAI), and the Control, Autonomy, Self-Realization, and Pleasure (CASP-19) questionnaire. The training cognitive game platform aimed to stimulate various cognitive aspects, including memory, attention, language, executive functions (reasoning, logical thinking), and visual and spatial skills. RESULTS: The participants of the training group showed a reduction in the MAC-Q, MacNair and Kahn, and GAI scores in the pre- and posttest comparison. Significant differences were identified between the groups regarding the total scores of the MAC-Q in the post-test, which was also evidenced by the logistic regression. CONCLUSION: Participation in a computerized cognitive intervention promoted reductions in memory complaints, frequency of forgetfulness, and anxiety symptoms, in addition to improving self-reported quality of life.

Amaurosis as an initial presentation of Takayasu arteritis in children.

Visual disturbances in Takayasu arteritis (TA) are common but tend to be late manifestations of the disease. However, its presence at diagnosis must alert TA to avoid sight disabilities. Herein, we present two children with TA that debuted with vision loss, and the results of the literature review displayed 58 subjects with vision loss before the diagnosis of TA. The world English literature was reviewed by searching the PubMed database of the National Library of Medicine for the terms "Takayasu Arteritis" and "Blindness" or "Amaurosis fugax", from 190 to 2021. Cases eligible must present vision loss before or at TA diagnosis. Our two patients who presented with amaurosis fulfilled the criteria for TA diagnosis. The first patient had a bilateral and transient visual loss, whereas the second had monocular and permanent amaurosis. Both patients were cursed with hypertension and demonstrated large vessel compromise; their clinical picture improved with corticosteroids and immunosuppressant therapy. We identified in the literature review sixteen patients with TA in case reports and 42 in case series, plus our two cases presented herein with monocular or bilateral vision loss at the time of diagnosis. Previous literature indicated that amaurosis represents a severely advanced disease. Herein, we reported two children with amaurosis as their pivotal symptom; they had significant head and neck vascular alterations, so prompt and aggressive treatment is needed to prevent disease progression and disability. Transient or permanent vision loss must alert the physician to include Takayasu arteritis in the differential diagnosis.

Changes in the total corneal refractive power after insertion of intrastromal rings in patients with keratoconus in short, medium and long term / Mudanças no poder refrativo total da córnea após a inserção de anéis intrastromais em pacientes com ceratocone a curto, médio e longo prazo

ABSTRACT Objective To analyze the short, medium and long-term efficacy and stability in 46 eyes with keratoconus, operated with Ferrara intrastromal corneal ring segments. Methods The primary endpoint was the mean keratometry of total corneal refractive power. We also studied the effects of age, degree of keratoconus and clinical phenotype on the results, as well as the following keratometry variations and aberrometry variations: flattest, most curved, mean, maximum, astigmatism, root mean square of primary coma aberration and root mean square of secondary coma aberration. Results The immediate postoperative reduction in mean keratometry of total corneal refractive power was 3.08±1.51 diopters (D) (p<0.001). At 4 years, the mean keratometry of total corneal refractive power increased to 0.57±0.96D (p=0.005). Between 4 and 7 years, there was no change in mean keratometry of total corneal refractive power (p=0.727). The degree of keratoconus was a factor affecting the efficacy of the intrastromal corneal ring segments, achieving a greater effect in those with a greater degree of keratoconus (p=0.012 between groups). The immediate postoperative reduction was 1.77±1.88D for the flattest, 3.91±2.30D for the most curved, 2.76±1.63D for the mean, 4.42±3.26D for the maximum, 2.15±2.68D for astigmatism, 1.03±0.83µm for root mean square of primary coma aberration and root mean square of secondary coma aberration (p<.001 in all cases). At 4 years, most curved increased by 0.42±0.78D (p=0.001), mean increased by 0.54±0.64 (p<0.001) and root mean square of primary coma aberration decreased 0.14±0.27µm (p=0.020). Conclusion Ferrara intrastromal corneal ring segment implantation is an effective and stable long-term treatment for patients with keratoconus. There is, however, partial regression in the medium term.

RESUMO Objetivo Analisar a eficácia e a estabilidade a curto, médio e longo prazo em 46 olhos com ceratocone, operados com segmentos de anel intrastromal corneano de Ferrara. Métodos A meta primária foi a ceratometria média de poder refrativo total da córnea. Também estudamos os efeitos da idade, grau de ceratocone e fenótipo clínico nos resultados, bem como as seguintes variações de ceratometria e variações de aberrometria: mais plana, mais curva, média, máxima, astigmatismo, raiz quadrada média da aberração comática primária e raiz quadrada média da aberração comática secundária. Resultados A redução pós-operatória imediata da ceratometria média do poder refrativo total da córnea foi de 3,08±1,51 dioptrias (D) (p<0,001). Aos 4 anos, a ceratometria média do poder refrativo total da córnea aumentou para 0,57±0,96D (p=0,005). Entre 4 e 7 anos, não houve mudança na ceratometria média da potência refrativa total da córnea (p=0,727). O grau de ceratocone foi um fator que afetou a eficácia dos segmentos do anel intrastromal da córnea, alcançando um efeito maior naqueles com maior grau de ceratocone (p=0,012 entre grupos). A redução pós-operatória imediata foi de 1,77±1,88D para a mais plana, 3,91±2,30D para a mais curva, 2,76±1,63D para a média, 4,42±3,26D para a máxima, 2,15±2,68D para o astigmatismo, 1,03±0,83µm para a raiz quadrada média da aberração comática primária e raiz quadrada média da aberração comática secundária (p<0,001 em todos os casos). Aos 4 anos, a maioria das curvas aumentou 0,42±0,78D (p=0,001), a média aumentou 0,54±0,64 (p<0,001) e a raiz quadrada média da aberração comática primária diminuiu 0,14±0,27µm (p=0,020). Conclusão O implante de anel intrastromal corneano Ferrara é um tratamento eficaz e estável a longo prazo para pacientes com ceratocone. Há, no entanto, uma regressão parcial a médio prazo.

Expresión clínica de la COVID-19 en pediatría de atención primaria: estudio COVIDPAP / COVID-19 clinical features in primary care: COVIDPAP study

Objetivos: En España, las pruebas diagnósticas de COVID-19 en atención primaria estuvieron disponibles desde mayo de 2020. Previamente la mayoría de los estudios describían pacientes hospitalarios: la fiebre y la tos eran los síntomas más frecuentes. Interesaba conocer la expresión clínica de la COVID-19 pediátrica en la comunidad. Métodos: Estudio descriptivo analítico observacional de casos pediátricos (0-14 años) de 255 pediatras de atención primaria españoles, del 12/5/2020 al 30/4/2021. Los diagnósticos se determinaron por PCR, test rápido de detección de antígeno o serología IgG positiva. Resultados: Se incluyeron 10.021 niños, 48,4% mujeres, con una edad media de 8,04±4,17 años. Se detectó la infección por búsqueda de contactos (70,9%) o síntomas compatibles (18,8%). El hogar familiar fue la principal fuente de contagio (64,9%), seguido por los colegios (10%) o de origen desconocido (9,9%). No hubo diferencias significativas en la incidencia entre temporadas vacacionales o lectivas. El 43,2% fueron asintomáticos. Los síntomas más frecuentemente encontrados fueron rinorrea en menores de 2 años, fiebre entre 3 y 8 años y cefalea en mayores de 9 años. Se describen exhaustivamente los síntomas y signos observados por edad. Se hospitalizaron a 8 pacientes, uno con un síndrome inflamatorio multisistémico. No hubo fallecimientos. Conclusiones: La COVID-19 es una enfermedad leve con un gran número de casos asintomáticos, con pocas hospitalizaciones y fallecimientos. El lugar principal de transmisión es el domicilio y el cierre de colegios debería ser el último recurso para controlar la pandemia. No se pudo describir un cuadro clínico característico de la enfermedad. (AU)

Objectives: In Spain, the tools to diagnose COVID-19 were available in primary care from May 2020. Previously most studies described inpatients, and fever and cough were the most frequent symptoms. This study aims to define the clinical picture of the pediatric COVID-19 in the community. Methods: A descriptive and analytical observational study was performed including pediatric cases (0-14y) from 255 pediatricians, proportionally distributed to its population, from primary health centers in Spain, from 12th May 2020 to 30th April 2021. Diagnostics were made by PCR detection of viral RNA, rapid antigen detection test or positive IgG serology. Results: There were 10,021 positive children included, 48.4% women, mean age 8,04±4.17 years. Infection was detected due to contact tracing (70.9%), compatible symptoms (18.8%). Household was the main source of transmission (64.9%), followed by school setting (10%) or unknown (9.9%). We did not find any significant differences in the incidence between holidays and school terms. 43.2% of the children were asymptomatic. Most frequent symptoms are rhinorrhea in <2y, fever in 3-8y and headache in >9y. An exhaustive description of objective and subjective symptoms by age is made. 18 patients were hospitalized, one with multisystem inflammatory syndrome in children. There were no deaths. Conclusions: Pediatric COVID-19 is a mild disease, with a large number of asymptomatic cases, with very few hospital admissions and deaths. The main setting for transmission is the household, and school closures should be a last resource measure during the COVID-19 pandemic. A specific clinical picture of pediatric COVID-19 was not found. (AU)

Trifocal IOL Implantation in Eyes With Previous Laser Corneal Refractive Surgery: The Impact of Corneal Spherical Aberration on Postoperative Visual Outcomes.

PURPOSE: To analyze corneal aberrations and factors affecting visual outcomes after implantation of a trifocal intraocular lens (IOL) in eyes previously treated with laser corneal refractive surgery. METHODS: This retrospective case series included 222 consecutive eyes implanted with the trifocal FineVision Micro-F IOL (PhysIOL) after laser corneal refractive surgery. The series was divided into two groups according to safety outcomes after lensectomy: eyes with loss of one or more lines of corrected distance visual acuity (CDVA) [n = 59, 26.5%]) (failed eyes group) and eyes with no loss or gain in CDVA lines (n = 163, 73.4%]) (successful eyes group). Distribution of tomographic corneal aberrations (spherical aberration [Z40], comatic and root mean square of higher order aberrations [RMS-HOA]), laser corneal refractive surgery error, kappa angle, and CDVA after laser corneal refractive surgery were compared among both groups. RESULTS: Mean CDVA after lensectomy was 0.15 ± 0.07 logMAR (range: 0.05 to 0.30 logMAR) versus 0.03 ± 0.04 logMAR (range: 0.00 to 0.15 logMAR) in the failed and successful eyes groups, respectively (P < .001). Comparison of both groups showed that failed eyes had a statistically significantly higher grade of hyperopic laser corneal refractive surgery than successful eyes measured as mean sphere (+0.71 ± 3.10 diopters [D] [range: -7.75 to +6.00 D] vs -0.46 ± 3.70 D [range: -10.75 to +6.00 D], P < .01), spherical equivalent (+0.27 ± 3.10 D [range: -8.00 to +5.50 D] vs -0.97 ± 3.60 D [range: -12.50 to +4.90 D], P < .05), and percentage of hyperopic laser corneal refractive surgery (64% vs 43.5%, P < .05). Corneal aberration analysis showed that mean Z40 values were significantly more negative in the failed eyes group than in the successful eyes group (+0.07 ± 0.40 mm [range: -0.82 to +0.65 mm] vs +0.18 ± 0.37 mm [range: -0.79 to +0.87 mm], P < .05). Laser corneal refractive surgery cylinder was distributed homogeneously between both groups, as well as coma and RMS-HOA, kappa angle, and CDVA after laser corneal refractive surgery that were not statistically significant. CONCLUSIONS: Surgeons should consider tomographic corneal spherical aberration after implantation of a trifocal IOL in eyes after keratorefractive surgery, particularly in eyes previously treated with hyperopic laser corneal refractive surgery, to prevent loss of lines of visual acuity after lensectomy.

Identification of Seniors at Risk: transcultural adaptation for Brazilian Portuguese.

OBJECTIVE: To perform cross-cultural adaptation of the Identification of Seniors at Risk tool. METHODS: This methodological study was based on the guidelines process proposed by Beaton, attending the stages of translation, back-translation, judgment by judges and content validation of the Identification of Seniors at Risk tool. The goal of this tool is to allow the identification of the elderly at risk for hospitalization, composed of six dichotomous questions (yes or no) related to functional decline, comorbidities, previous hospitalization (last 6 months), visual impairment, significant changes in memory and polypharmacy. Two bilingual translators and 16 health professionals with hospital and academic performance in the fields of geriatrics and gerontology participated in the study. RESULTS: Differences were observed between the initial translations and the final version. Changes were made to questions 1, 3, 4 and 6. In the last question, an item was modified to meet the Brazilian polypharmacy criterion. After the cross-cultural adaptation, the tool showed 100% agreement between the judges. CONCLUSION: Brazilian Identification of Seniors at Risk has indexes of verbal comprehension and high content validity.

Fatores associados a hospitalização de idosos longevos residentes no Distrito Federal ­ Brasil / Factors associated with hospitalization for long elderly residents in the Federal District ­ Brazil / Factores asociados a la hospitalización de ancianos largo residentes en el Distrito Federal - Brasil

Foram investigados 208 idosos longevos (80 anos e mais) atendidos em ambulatório do Distrito Federal entre os anos de 2016 a 2018. Utilizaram-se testes de rastreio cognitivo, desempenho funcional, fragilidade e questionários padronizados.Ahospitalização no último ano foi associada a idade mais avançada, menor escolaridade, maior prevalência de declínio cognitivo, e possuir fragilidade nos domínios perda de peso e força de preensão manual. Após ajustes segundo modelo logístico múltiplo permaneceram associadas à hospitalização as variáveis escolaridade, fragilidade perda de peso e número de consultas médicas no último ano. Nesse contexto, para prevenção da hospitalização na velhice avançada faz-se necessário investimentos em medidas de gerenciamento de caso, qualificação da atenção em saúde, rastreio e manejo da fragilidade.

The objective of this study was to analyze the factors associated with hospitalization of elderly people aged 80 years and over residing in the Federal District -Brazil. A total of 208 long-lived elderly (80 years and older) treated at an outpatient clinic of the Federal District between 2016 and 2018 were investigated. Cognitive screening, functional performance, frailty and standardized questionnaires tests were used. Hospitalization in the last year was associated with older age, lower education, higher prevalence of cognitive decline, and frailty criteria in the weight loss and handgrip strength. After adjustments according to the multiple logistic model, the variables schooling, frailty weight loss and number ofmedical appointments in the last year remained associated with hospitalization.In this way, to prevent hospitalization in advanced old age, investments in case management measures, health care qualification, screening and management of frailty are required.

Identification of Seniors at Risk: transcultural adaptation for Brazilian Portuguese

ABSTRACT Objective To perform cross-cultural adaptation of the Identification of Seniors at Risk tool. Methods This methodological study was based on the guidelines process proposed by Beaton, attending the stages of translation, back-translation, judgment by judges and content validation of the Identification of Seniors at Risk tool. The goal of this tool is to allow the identification of the elderly at risk for hospitalization, composed of six dichotomous questions (yes or no) related to functional decline, comorbidities, previous hospitalization (last 6 months), visual impairment, significant changes in memory and polypharmacy. Two bilingual translators and 16 health professionals with hospital and academic performance in the fields of geriatrics and gerontology participated in the study. Results Differences were observed between the initial translations and the final version. Changes were made to questions 1, 3, 4 and 6. In the last question, an item was modified to meet the Brazilian polypharmacy criterion. After the cross-cultural adaptation, the tool showed 100% agreement between the judges. Conclusion Brazilian Identification of Seniors at Risk has indexes of verbal comprehension and high content validity.

Adaptação transcultural do Team Member Perspectives of Person-centered Care (TM-PCC) em pessoas idosas institucionalizadas / Cross-cultural adaptation of the Team Member Perspectives of Person-Centered Care (TM-PCC) in institutionalized older adults

Resumo Objetivo Realizar a tradução, retrotraduação para o português falado no Brasil e a adaptação transcultural do instrumento Team Member Perspectives of Person-Centered Care (TM-PCC) e ainda, a sua validade de constructo. O objetivo do TM-PCC é avaliar a frequência de comportamentos e de práticas de cuidados centrados no indivíduo segundo os profissionais que atuam nas Instituições de Longa Permanência para Idosos (ILPIs). Método Foram seguidos o processo de tradução, retrotraduação e adaptação transcultural por meio da equivalência semântica, idiomática, experiencial e conceitual realizado por cinco juízes especialistas da área de Geriatria e da Gerontologia e, por fim, aplicou-se o instrumento piloto em 49 profissionais de quatro ILPIs de três estados brasileiros. Resultados Após a avaliação realizada pelos juízes especialistas, obteve-se discordância quanto aos termos "previous associations", "fufilling relationships" e "incorporate this caring into my daily routine", os quais foram substituídos por "histórias pregressas", "relações satisfatórias", e "incorporar esse cuidado na minha rotina diária". Após as correções e revisões, o questionário foi reenviado aos juízes, obtendo-se 100% de concordância. Observou-se boa compreensão das questões durante a aplicação piloto e boa consistência interna por meio do alfa de Cronbach= 0,78. Conclusão O TM-PCC pode ser ferramenta útil para avaliação dos cuidados centrados ao indivíduo em ILPIs, no Brasil, segundo a avaliação de profissionais. Isso possibilitará ao gestor ou profissional supervisor de cuidados, planejar e desenvolver intervenções educacionais e de gestão voltadas a promoção dos cuidados centrados ao indivíduo nas ILPI.

Abstract Objective carry out the translation and back-translation into Brazilian Portuguese, and the cross-cultural adaptation of the instrument called Team Member Perspectives of Person-Centered Care (TM-PCC), as well as its construct validity. The objective of the TM-PCC is to assess the frequency of behaviors and care practices centered on the individual according to professionals who work in Long-Term Care Facilities for Older Adults (ILPIs). Method The process of translation, back-translation, and cross-cultural adaptation was followed through semantic, idiomatic, experiential, and conceptual equivalence carried out by five expert judges in the field of Geriatrics and Gerontology, with the pilot instrument being administered to 49 professionals from four ILPIs in three Brazilian states Results After the assessment was conducted by the expert judges, disagreement was found regarding the terms "previous associations," "fulfilling relationships," and "incorporate this caring into my daily routine," which were replaced by"histórias pregressas" (past stories), "relações satisfatórias" (satisfactory relationships), and "incorporar esse cuidado na minha rotina diária" (incorporate this care into my daily routine). After these corrections and revisions, the questionnaire was sent back to the judges, who were in total agreement. Good understanding of the questions was observed during the pilot application and good internal consistency through Cronbach's alpha (0.78 Conclusion The TM-PCC can be a useful tool for assessing individual-centered care in ILPIs in Brazil, according to the assessment of professionals. This will enable patient care managers or supervisors to plan and develop educational and management interventions aimed at promoting individual-centered care in ILPIs.

Dilemas sobre o uso da máscara facial no pós-pandemia: uma medida preventiva e controle de doenças respiratórias infectocontagiosas / Dilemmas about the use of face masks in post-pandemic times: a preventive measure and control of infectious and contagious respiratory diseases

Objetivou-se compreender os motivos da adesão ou não do participante ao uso da máscara em caso de ter alguma "gripe"; conhecer as ações realizadas pelos participantes para evitar a transmissão quando apresentavam os sintomas de gripe antes da pandemia; identificar a opinião dos participantes sobre o usos de máscara antes da pandemia; verificar as sensações quanto ao uso de máscara facial na pandemia e averiguar a aceitação da população quanto ao uso de máscara facial em caso de sintomas de doenças respiratórias infectocontagiosas na pós-pandemia. Consiste-se em um estudo descritivo, exploratório, com abordagem qualitativa, realizado com 62 participantes usuários de transporte coletivo. Utilizou-se entrevistas semiestruturadas no mês de outubro de 2020. Os dados coletados foram submetidos à análise segundo a fenomenologia social e categorizados conforme abordagem fenomenológica. As motivações para usar a máscara em locais públicos em caso de gripe na pós-pandemia, mostram a preocupação com a prevenção e a proteção consigo e com outros. A não adesão refere-se à dificuldade no convívio social e o desconforto. Assim, compreende-se que o autocuidado esteve presente entre vários discursos dos participantes e que quase a totalidade dos participantes, em caso de "gripe" utilizarão a máscara depois da pandemia. Conclui-se que a educação da população relacionada ao uso de máscara facial na pós-COVID-19, em locais públicos, visando diminuir a disseminação e a contaminação pelas doenças respiratórias infectocontagiosas é primordial.

The objective of this study was to understand the reasons for the participant's adherence or not to the use of mask in case of catching a "flu"; to analyze the actions taken by the participants to avoid transmission when they had flu symptoms before the pandemic; identify the opinion of the participants on the use of masks before the pandemic; to verify the general feeling towards the use of a face mask in the pandemic, and to verify the acceptance of the population regarding the use of a face mask in case of symptoms of infectious and contagious respiratory diseases in post-pandemic times. This consists of a descriptive, exploratory study, with a qualitative approach, carried out with 62 participants who use public transportation. Semi-structured interviews were used in October 2020. The data collected were subjected to analysis according to social phenomenology and categorized according to a phenomenological approach. The motivations for wearing the mask in public places in case of flu in post-pandemic times show the concern with prevention and protection for themselves and others. Non-adherence refers to difficulty in socializing and discomfort. Thus, it is understood that self-care was present among several answers and that almost all the participants, in case of a "flu", will wear a mask after the pandemic. It is concluded that instructing the population regarding the use of a face mask in public places in post-COVID-19 times in order to reduce the spread and contamination by infectious and contagious respiratory diseases is of paramount importance.

Estudio multicéntrico nacional sobre la organización de las consultas de Pediatría de Atención Primaria en España durante la primera ola de la pandemia de COVID-19 / Nationwide multicentre study on the organization of primary care paediatrics services in the first wave of the COVID-19

Introducción: la pandemia de COVID-19 ha originado cambios organizativos en los centros de Atención Primaria (AP). El objetivo de este estudio es conocer los cambios producidos en las consultas de Pediatría de AP durante la primera ola de la pandemia por COVID-19. Material y métodos: estudio observacional, descriptivo, retrospectivo, multicéntrico y de ámbito nacional, a través de una encuesta dirigida a los pediatras de Atención Primaria (PAP) distribuida en junio de 2020. Se recogieron datos desde el 16 de marzo al 10 de mayo de 2020, dividido en cuatro periodos de dos semanas cada uno. Se preguntó sobre la forma de trabajar en los centros durante ese periodo: existencia de sistema de triaje, modalidad de atención, presencial o telefónica, y volumen de consultas atendidas. Resultados: se consideraron válidas 105 encuestas de las 110 contestadas por PAP. Participaron pediatras de 17 comunidades autónomas (el 72,4% de medio urbano). Cubrían una población de 107 715 pacientes. Realizaron consulta telemática el 90,5% (38,1% antes de la pandemia). En todos los centros se realizó triaje. La media de pacientes atendidos por profesional en cada uno de los periodos considerados fue de 144, 114, 123, 136 (277, 214, 207 y 233 en los mismos periodos del año 2019). En el 88,6% de cupos se realizaron visitas presenciales del programa de salud infantil (PSI). De toda la población atendida, los PAP notificaron ingresos por cualquier motivo de 79 pacientes y en la unidad de cuidados intensivos (UCI) de siete. No se les notificó ningún fallecimiento. Conclusiones: durante el periodo inicial de pandemia COVID-19 se registró en las consultas de Pediatría de AP un aumento muy importante de la consulta telemática y, paralelamente, una disminución significativa de la consulta presencial. Se instauraron sistemas de triaje. Se mantuvo una actividad muy alta en el PSI. Hubo un número muy bajo de ingresos y casos graves (AU)

Introduction: the COVID-19 pandemic has driven changes in the organization of care delivery in primary care (PC) centres. The objective of our study was to describe the changes in PC paediatric care that took place in the first wave of the COVID-19 pandemic. Material and methods: we conducted a nationwide, multicentre, retrospective, observational and descriptive study through a survey of PC paediatricians with distribution of the questionnaire in June 2020. We collected data from March 16 to May 10, 2020, divided in four 2-week periods. We asked about care delivery in these centres during this period: use of triage systems, modalities of care delivery (in person or by telephone) and volume of visits. Results: we received 105 responses by PC paediatricians, of which 110 were considered valid. We obtained responses from paediatricians in 17 autonomous communities (72.4% in urban settings). Respondents served a cumulative population of 107 715 patients. A total of 90.5% provided remote care (38.1% did before the pandemic). Triage was conducted in all centres. The mean number of patients managed per paediatrician in each of the time intervals under study was 144, 114, 123 and 136 (compared to 277, 214, 207 and 233 in the same periods in 2019). In 88.6% of the caseloads, in-person appointments were conducted as part of the child health programme (CHP). The total number of hospital admissions for any reason in the cumulative catchment population was of 79 patients, and the number of admissions to the intensive care unit was 7. The respondents did not report any deaths. Conclusions: in the first wave of the COVID-19 pandemic, there was a substantial increase in remote primary care paediatric visits parallel to a significant decrease in in-person visits. Triage systems were implemented. There was still substantial activity in the CHP. The number of hospital admissions and cases of serious disease was very low (AU)

Impact of Cations (Na+, K+, Mg+2) and Anions (F-, Cl-, SO42-) Leaching from Filters Packed with Natural Zeolite and Ferric Nanoparticles for Wastewater Treatment.

Natural zeolites have been employed to adsorb contaminants in water. This study is aimed to evaluate the cation and anion leaching from the zeolite after the wastewater was passed through filters packed with a natural zeolite (heulandite-CaAl2Si7O18·6H2O). Eight treatments were evaluated in a 2 × 2 × 2 factorial treatment design. Factor A was the zeolite with two levels: 127 g and 80.4 g. Factor B was the nanoparticles with two levels: one bag (3.19 g) and two bags (6.39 g); and Factor C was the use of a magnet: with and without. There were two replications; hence, a total of 16 filters were employed. The water was obtained from a municipal wastewater treatment plant (MWTP). The cations (Na+, K+; Mg+2 and Ca+2) and anions (F-, Cl- and SO42-) were measured before (influent = IW) and after filtering (effluent = EW) three times. All treatments leached the cations Na+ (EW in a range of 175 to 232 ppm), K+ (EW in a range of 15.4 to 33.2 ppm), and Mg+2 (EW in a range of 7.40 to 10.8 ppm) but did not leach Ca+2. Likewise, the treatments leached the anions F- (EW in a range of 7.59 to 8.87 ppm), Cl- (EW in a range of 85.9 to 120 ppm), and SO42- (EW in a range of 139 to 146 ppm). We conclude that this natural zeolite leaches cations (except Ca+2) and anions in MWTP passed through filters. Therefore, its application in wastewater treatment should be considered for purposes such as agriculture and animal production and not for drinking water.
