Interculturalidad: más allá de la diversidad Reflexiones y experiencias en contextos latinoamericanos / Interculturality: beyond diversity Reflections and experiences in Latin American contexts

Este libro tiene como origen las diversas reflexiones originadas por la ejecución de un trabajo de investigación en el área de la salud con comunidades indígenas de la Amazonia colombiana denominado: "Estrategia de Atención Primaria en Salud con enfoque intercultural e investigación Acción Participativa para la prevención del cáncer de cuello uterino en el resguardo indígena de El Paujil" (Colombia) y desarrollado por lideresas pertenecientes a la región e investigadores de las universidades Fundación Universitaria de Ciencias de la Salud, FUCS; Universidad de Ciencias Aplicadas y Ambientales, UDCA; y Universidad El Bosque, con la cofinanciación del Ministerio de Ciencia, Tecnología e Innovación de Colombia. Los avances del proyecto permitieron explorar las visiones sobre diversos temas de algunas comunidades indígenas de la Amazonia, en especial, los relacionados con la salud de las mujeres y sus roles en las familias y en las comunidades. El trabajo conjunto, mediante una metodología de investigación participativa alrededor de la prevención del cáncer de cuello uterino, incluyó en primer lugar el análisis de la interculturalidad como un enfoque que coincide con los postulados de respeto por los valores culturales y las diferencias.

This book has as origin the diverse reflections originated by the execution of a research work in the area of health with indigenous communities of the Colombian Amazon called: "Primary Health Care Strategy with intercultural approach and Participatory Action Research for the prevention of cervical cancer in the indigenous reservation of El Paujil" (Colombia) and developed by leaders belonging to the region and researchers from the universities Fundación Universitaria de Ciencias de la Salud, FUCS; Universidad de Ciencias Aplicadas y Ambientales, UDCA; and Universidad El Bosque, with co-financing from the Ministry of Science, Technology and Innovation of Colombia. The progress of the project made it possible to explore the views on various topics of some indigenous communities in the Amazon, especially those related to women's health and their roles in the families and communities. The joint work, through a participatory research methodology on cervical cancer prevention, included first of all the analysis of interculturality as an approach that coincides with the postulates of respect for cultural values and differences.

Concepções da saúde sexual e reprodutiva entre mulheres curipacas em situação de mobilidade humana / Conceptions of sexual and reproductive health in Kurripaco women in conditions of human mobility / Concepciones de la salud sexual y reproductiva en mujeres kurripacos en condición de movilidad humana

Resumo A migração dos povos indígenas apresenta tensões entre as tradições ancestrais e a visão ocidental com implicações para a saúde pública, especialmente a saúde sexual e reprodutiva. Este texto teve como objetivo analisar as concepções de saúde sexual e reprodutiva de mulheres indígenas curipacas de uma reserva indígena no departamento de Guainía (Colômbia). Trata-se de um estudo de caso, com uma amostra de 40 mulheres indígenas curipacas, residentes na reserva Paujil, em Guainía, provenientes de diferentes comunidades. Foram aplicadas entrevistas semiestruturadas elaboradas com membros da mesma comunidade e traduzidas para a língua curipaca. Três categorias resultaram da análise: impacto da mobilidade de mulheres indígenas; autonomia relativa como estrutura da sexualidade; e concepções da abordagem ocidental da saúde sexual e reprodutiva. Esta última categoria identificou que as participantes não têm conhecimento sobre a saúde sexual e reprodutiva desde o ponto de vista ocidental e vislumbram suas próprias formas de compreender a saúde-doença como parte integrante de todas as dimensões da vida/morte. A inter-relação entre as tradições ancestrais dos povos indígenas e a visão ocidental sobre a saúde requer uma abordagem intercultural de profissionais, serviços e do sistema de saúde para que reconheça a autonomia pessoal e relacional desses povos.

Abstract The migration of indigenous peoples presents tensions between ancestral traditions and the western vision, with implications for public health, particularly sexual and reproductive health. To analyze the conceptions of sexual and reproductive health of Kurripaco indigenous women from a reservation in the department of Guainía. Case study in a sample of 40 Kurripaco indigenous women, residents of the Paujil reservation, Guainía, Colombia, from different communities. Semi-structured interviews built with members of the same community and translated into the native language will be applied. Three categories emerged from the analysis: impact of mobility on indigenous women; Relative autonomy as frameworks of sexuality and conceptions against the Western approach to sexual and reproductive health. In this last category, it is found that the aspects of sexual and reproductive health as a Western construct are unknown by the participants, but instead they glimpse their own ways of understanding health-disease as an integrated part of all dimensions of life/death. The interrelationship between the ancestral traditions of native peoples and the western approach to health requires professionals, services, and the system to adopt an intercultural approach that recognizes relative personal and relational autonomy.

Resumen La migración de pueblos indígenas presenta tensiones entre las tradiciones ancestrales y la visión occidental, con implicaciones para la salud pública, particularmente en salud sexual y reproductiva. Este texto tuvo por objetivo analizar las concepciones sobre salud sexual y reproductiva de mujeres indígenas kurripacos de un resguardo del departamento de Guainía (Colombia). Se trata de un estudio de casos en una muestra de 40 mujeres indígenas kurripacos, residentes en el resguardo Paujil, en Guainía, procedentes de distintas comunidades. Se aplicaron entrevistas semiestructuradas construidas con miembros de la misma comunidad y traducidas a lengua nativa. Tres categorías emergieron del análisis: Impacto de la movilidad en las mujeres indígenas; autonomía relativa como marcos de la sexualidad; y concepciones frente al abordaje occidental de la salud sexual y reproductiva. Esta última categoría identificó que los aspectos de la salud sexual y reproductiva como constructo occidental son desconocidos por las participantes, quienes vislumbran formas propias de comprender la salud-enfermedad como parte integrada a todas las dimensiones de la vida/muerte. La interrelación entre las tradiciones ancestrales de los pueblos originarios y el abordaje occidental de la salud exige a profesionales, servicios y sistema un enfoque intercultural que reconozca la autonomía relativa personal y relacional.

Estrategia de atención primaria en salud con enfoque intercultural e investigación acción participativa en la prevención de cáncer de cuello uterino en 5 etnias indígenas del Resguardo de Paujil, departamento de Guainía: memorias del proyecto / Primary health care strategy with intercultural approach and participatory action research in the prevention of cervical cancer in 5 indigenous ethnic groups of the Paujil Resguardo, department of Guainía: project proceedings

El cáncer de cuello uterino es un problema de salud pública al ubicarse como el cuarto cáncer más común entre las mujeres a nivel mundial, con una estimación de 604.127 casos nuevos y 341.831 muertes para el año 2020. El 90% de estas muertes fue aportado por países de ingresos bajos y medios y entre 2015 y 2020 se presentaron 1.495.211 casos de cáncer de cuello uterino (1). En Colombia, el número de casos nuevos de cáncer de cuello uterino para el 2022 fue de 4.570 y 2.435 muertes (2). En el 99,7% de los casos de cáncer de cuello uterino, la causa asociada fue la infección persistente por una de las cepas de VPH catalogadas como de alto riesgo (3); en este sentido, la vacunación se considera como una medida eficaz para la reducción de la incidencia del cáncer de cuello uterino, tal como lo reporta un estudio realizado en Dinamarca, en el que se estimó una reducción del 86% en la tasa de incidencia del cáncer de cuello uterino entre las niñas y mujeres vacunadas a los 16 años o antes (4). Asimismo, el cribado regular mediante pruebas de Papanicolaou y pruebas del VPH permite identificar células cervicales con lo que podría reducirse la incidencia entre un 69% y un 81% (5).

Cervical cancer is a public health problem by ranking as the fourth most common cancer among women worldwide, with an estimated 604,127 new cases and 341,831 deaths by 2020. Ninety percent of these deaths were contributed by low- and middle-income countries and between 2015 and 2020 there were 1,495,211 cases of cervical cancer (1). In Colombia, the number of new cases of cervical cancer by 2022 was 4,570 and 2,435 deaths (2). In 99.7% of cervical cancer cases, the associated cause was persistent infection by one of the HPV strains classified as high risk (3); in this sense, vaccination is considered an effective measure for reducing the incidence of cervical cancer, as reported by a study conducted in Denmark, which estimated an 86% reduction in the incidence rate of cervical cancer among girls and women vaccinated at 16 years of age or earlier (4). Likewise, regular screening by Pap smears and HPV tests can identify cervical cells, which could reduce the incidence by 69% to 81% (5).

Activity of propolis from Mexico on the proliferation and virulence factors of Candida albicans.

BACKGROUND: This research evaluated the anti-Candida albicans effect of Mexican propolis from Chihuahua. Chemical composition of the ethanolic extract of propolis was determined by GC-MS, HPLC-DAD, and HPLC-MS. The presence of anthraquinone, aromatic acid, fatty acids, flavonoids, and carbohydrates was revealed. RESULTS: The anti-Candida activity of propolis was determined. The inhibitions halos were between 10.0 to 11.8 mm; 25% minimum inhibitory concentration (0.5 mg/ml) was fungistatic, and 50% minimum inhibitory concentration (1.0 mg/ml) was fungicidal. The effect of propolis on the capability of C. albicans to change its morphology was evaluated. 25% minimum inhibitory concentration inhibited to 50% of germ tube formation. Staining with calcofluor-white and propidium iodide was performed, showing that the propolis affected the integrity of the cell membrane. INT1 gene expression was evaluated by qRT-PCR. Propolis significantly inhibited the expression of the INT1 gene encodes an adhesin (Int1p). Chihuahua propolis extract inhibited the proliferation of Candida albicans, the development of the germ tube, and the synthesis of adhesin INT1. CONCLUSIONS: Given the properties demonstrated for Chihuahua propolis, we propose that it is a candidate to be considered as an ideal antifungal agent to help treat this infection since it would not have the toxic effects of conventional antifungals.

Evaluation the Potential of Onion/Laponite Composites Films for Sustainable Food Packaging with Enhanced UV Protection and Antioxidant Capacity.

Agro-industrial residues have attracted attention for their applications in the field of biodegradable packaging. Recently, our research group has developed onion-based films with promising properties for this type of application due to their non-toxicity, biocompatibility and biodegradability. Therefore, in this study, we investigated the effect of Laponite clay concentration on the physicochemical and antioxidant properties of the onion-based films, which were prepared by a casting method. The XRD and FTIR data confirm the presence of the mineral clay in the onion-based films. These findings are consistent with those obtained from FE-SEM analysis, which revealed the presence of typical Laponite grains. In terms of wettability, the results show that the clay decreases the hydrophilic character of the material but slightly increases the water vapor permeation. Optical characterization revealed that the materials exhibited zero transmittance in the UV region and increased opacity in the visible region for composites containing 5% and 10% Laponite. Furthermore, the antioxidant test demonstrated higher antioxidant potential in the composites compared to the pure films. Consequently, these results suggest that the formation of Laponite and onion composites could be an essential strategy for developing natural polymers in the field of food contact packaging.

Improving knowledge, attitudes, and practices on dengue and diarrhea in rural primary school students, their parents, and teachers in Colombia: A cluster-randomized controlled trial.

BACKGROUND: Improved education on water-related diseases in schools could help to reduce disease burden. This paper presents specific results on knowledge, attitudes and practices (KAP) of a cluster-randomized controlled trial to reduce diarrheal disease and dengue entomological risk factors in rural primary schools in Colombia. The aim was to investigate whether enhanced educational interventions on dengue and diarrheal disease in schools could improve KAP scores related to these diseases in students and teachers in rural primary schools, as well as the students' parents. METHODOLOGY/PRINCIPAL FINDINGS: A factorial cluster-randomized controlled trial was carried out in 35 rural primary schools in two municipalities in Cundinamarca, central Colombia. Schools were randomized into four arms: interventions related to diarrheal disease (DIA), dengue (DEN), both (DIADEN), or no interventions (control, CON). Both educational and physical interventions to reduce risk factors of dengue and diarrhea were implemented. Comprehensive teachers' manuals were developed and deployed to guide the learning activities. The intervention was carried out over two school years. The knowledge scores of students receiving dengue interventions (DEN, DIADEN) increased by 1.16 point score (0.75-1.56, p<0.001) and those receiving diarrhea interventions (DIA, DIADEN) increased by 1.15 point score (0.67-1.63, p<0.001). The attitude and practice scores of students receiving the diarrhea interventions increased (Attitudes: 0.41 [0.11-0.71, p = 0.01]; Practices: 0.33 [0.01-0.65, p = 0.042]), but not for those receiving the dengue interventions (p = 0.31 and p = 0.08, respectively). CONCLUSIONS/SIGNIFICANCE: There were increases in knowledge scores among students, their teachers and their parents for both diseases. However, the attitudes and practices components were not affected to the same extent. The hypothesis that the students would disseminate knowledge acquired from the educational interventions to their parents was confirmed for dengue, but not for diarrhea. TRIAL REGISTRATION: ISRCTN40195031 The trial is registered in the Current Controlled Trials under Infections and Infestations category.

Thermal Stability and Crystallization Behavior of Contaminated Recycled Polypropylene for Food Contact.

Polypropylene is one of the most widely used polymers, especially in the food packaging industry, which causes negative environmental effects. Recycling is a good option to partially solve this environmental problem. Thus, the polymer was contaminated with a cocktail to simulate the conditions of disposal and recycling following FDA guidelines. The influence of contaminants on recycled PP was analyzed by quiescent and nonquiescent crystallization. It was found that the contaminants alter the crystallization flow since longer induction times were observed for all contaminated samples. Also, the thermal behavior was performed considering that the thermogravimetric (TGA) results indicated an increase in the stability with the presence of contaminants. Therefore, a deep investigation using the induced oxidation time and induced oxidation temperature was performed. The contaminants play an important role in the crystallization process, as well as, in the degradation of the samples. Furthermore, the use of TGA and DSC as complementary techniques is fundamental to analyze this influence.

Microwave-induced self-ignition: An efficient approach for high purity graphite digestion and multitechnique halogen determination.

In this work, high purity graphite, a high chemically stable material, was effectively digested using a single method allowing compatible solutions for the further multitechnique determination of halogens by: ion chromatography (F and Cl), inductively coupled plasma mass spectrometry (Cl, Br and I) and by ion selective electrode (only for F). The recent system using microwave-induced self-ignition (MISI) is based on the strong interaction between microwave radiation and graphite in a closed system pressurized with oxygen (Maxwell-Wagner effect). Carbon-based materials present intense and specific interfacial polarization when exposed to microwave electromagnetic field resulting in a fast heating rate. This effect associated to a pressurized oxygen system, provides a quick self-ignition of carbon-based materials and consequent combustion/digestion of organic matrices. Under optimized conditions, sample masses up to 600 mg were fully digested in a quartz vessel under 20 bar of oxygen pressure and using just a diluted solution (100 mmol L-1 NH4OH) for the quantitative absorption of all the analytes. MISI method was validated, and the accuracy (better than 94%) was evaluated by comparison of results obtained by pyrohydrolysis for two coal certified reference materials as well as with subsequent analytes determination by the three techniques: IC, ICP-MS and ISE. It is important to point out that no filter paper disks, electrical connections or other ignition aids are required as in the case of previous or classical combustion methods. Moreover, just a diluted absorbing solution was used resulting in negligible blanks and relatively low limits of detection. The digestion efficiency was higher than 99%, making the proposed method a suitable and powerful alternative for the quasi complete digestion of graphite and determination of halogens virtually free of interferences.

A Perspective of the COVID-19 Pandemic in the Plastic Waste Management and Cooperatives of Waste Pickers in Brazil.

Brazil is the fourth largest producer of plastic waste in the world. Among all the challenges the country had faced in the development of public policies for the banning of single-use plastics, the new coronavirus pandemic scenario determined the suspension of these laws indefinitely. In 2020, Brazil became the global epicenter of COVID-19. This scenario changed the habit and behavior of Brazilian consumers, who increased the consumption of plastics due to their importance in applications as protective material. The country also has social problems related to waste management that depend mainly on waste pickers. These workers need social visibility and protection not only to face the current health crisis but also to guarantee their income and survival. This work aims to discuss the increase in single-use plastics that are not intended for recycling and the respective environmental, economic, and social impacts for the country. We demonstrate the lack of data on waste management in Brazil and highlight the importance of the social inclusion of waste pickers for a circular economy. Especially after the change of scenario with the COVID-19 pandemic, the country must have adequate planning and improvements in waste management, recycling programs, and political intervention to raising awareness among the population and guaranteeing social rights for waste pickers.

Prevalence of abdominal aortic aneurysms in four different metropolitan areas in Mexico.

OBJECTIVE: Epidemiological data on aneurysmal disease affecting the abdominal aorta in Latin American countries are limited. In our institution, the National Institute of Medical Sciences and Nutrition Salvador Zubiran (INCMNSZ), we have reported an Abdominal Aortic Aneurysm (AAA) prevalence of 3.26% in patients at risk from our Ultrasound (US) screening program. We aim to determine and compare the prevalence of undetected AAA in four different Metropolitan areas in Mexico to justify further US screening efforts. METHODS: A cross-sectional multicenter study was conducted in 9 different academic institutions. Abdominal Computed Tomographies (CT) from patients with age equal or greater than 55 years in our center (INCMNSZ), and in 65 year old patients and older in the remainder institutions were systematically reviewed. Abdominal aortic diameters were measured at the level of the superior (SMA) and inferior mesenteric arteries (IMA) in nonaneurysmal aortas and maximum diameters in the found AAA. Categorical data were analyzed by nonparametric statistic test at significance level (P < 0.05), the Pearson test was used to determine the correlation of age and aortic diameters. RESULTS: The cohort included a total of 12, 936 patients paired with respect gender (53% females, with a mean age of 69 years), the AAA prevalence found in the studied Mexican population was 3.08% (399 AAA patients). In centers where more than 200 CTs scans were reviewed, the prevalence was 4.03%, compared to the 4.63% found in centers with less than 200 studies (P = 0.41). In patients between the ages of 55 to 64 from INCMNSZ (3889 total), the prevalence was 0.77%, supporting the need of focused US-screening programs in individuals at the age of 65 and older in our country. CONCLUSIONS: The introduction of a national US Screening Program for the detection of AAA in Mexico represents a challenge in our current health system. This Multicenter initiative demonstrates that our AAA prevalence is not different to other international reports; imaging screening might represent cost-effective strategy for reduction of aneurysm-related mortality.

Challenges in the context of single-use plastics and bioplastics in Brazil: A legislative review.

Plastic has been present in our lives for the past century as an essential material for many commodity items. However, the same properties that make plastic convenient are also responsible for the current dramatic environmental pollution. As an alternative, most of the world has been working with technological innovations, and one of its strategies is the use of bioplastics. Despite being considered environmentally beneficial by some people, there are still developments and discussions that need to be made. This article aims to present a legislative review and discusses the difficulty in implementing policies related to the incentive of the bioplastics market, as well as presenting some state and municipal laws, already prohibiting single-use plastics in Brazil. These laws aim to encourage the substitution of these plastics for biodegradable ones. However, it still has gaps and a lack of clarification on how the banning of disposable plastics and their substitution will be beneficial since composting is still an incipient process in the country. It is also the purpose of this article to discuss the challenges in the context of the Circular Economy, as well as the potential solution based on the creation of public policies aimed at improving waste management, in addition to clearer legislation on alternatives to single-use plastics.

Bioactive Ag3PO4/Polypropylene Composites for Inactivation of SARS-CoV-2 and Other Important Public Health Pathogens.

The current unprecedented coronavirus pandemic (COVID-19) is increasingly demanding advanced materials and new technologies to protect us and inactivate SARS-CoV-2. In this research work, we report the manufacture of Ag3PO4 (AP)/polypropylene (PP) composites using a simple method and also reveal their long-term anti-SARS-CoV-2 activity. This composite shows superior antibacterial (against Staphylococcus aureus and Escherichia coli) and antifungal activity (against Candida albicans), thus having potential for a variety of technological applications. The as-manufactured materials were characterized by XRD, Raman spectroscopy, FTIR spectroscopy, AFM, UV-vis spectroscopy, rheology, SEM, and contact angle to confirm their structural integrity. Based on the results of first-principles calculations at the density functional level, a plausible reaction mechanism for the initial events associated with the generation of both hydroxyl radical •OH and superoxide radical anion •O2- in the most reactive (110) surface of AP was proposed. AP/PP composites proved to be an attractive avenue to provide human beings with a broad spectrum of biocide activity.

Analyzing the Effects of Silica Nanospheres on the Sol-Gel Transition Profile of Thermosensitive Hydrogels.

The insertion of nanoparticles into smart hydrogels can diversify their functionalities by a synergistic combination of the components properties within the hydrogels. While these hybrid systems are attractive to the biomaterials field, careful design and control of their properties are required since the new interactions between the polymer and the nanoparticles can result in changes or the loss of hydrogels stimuli response. In order to understand the physicochemical aspects of the thermoresponsive systems, nanocomposites of poly(N-vinylcaprolactam) (PNVCL) and silica nanoparticles with different sizes and concentrations were synthesized. The UV-vis and DLS techniques showed that the PNVCL has a sharp phase transition at 34 °C, while the nanocomposites have a diffuse transition. The nanocomposites showed an initial coil-globule transition before the phase transition takes place. This was identified by the evolution of the hydrodynamic diameter of the nanocomposite globules before the cloud point temperature (Tcp), which remained constant for PNVCL. This new transition profile can be described by two stages in which microscopic volume transitions occur first, followed by the macroscopic transition that forms the hydrogel. These results show that the proposed nanocomposites can be designed to have tunable stimuli response to smaller temperature variations with the formation of intermediate globule states.

Importance of profile of volatile and off-odors compounds from different recycled polypropylene used for food applications.

Nowadays, polypropylene is one of the most common polymers used in the food packaging industry due to its good functionality and relatively low cost. Nevertheless, usage of plastic disposable packaging can be a generator of plastic pollution having negative environmental effects. A feasible solution for this issue would be to recycle. The polypropylene samples were submitted to two processes, forced contamination, and recycling, and they were analyzed by solid-phase microextraction gas chromatograph-olfactometry-mass spectrometry. 45 different volatile compounds were identified and 9 of them presented distinct odoriferous activities. Among them, two important markers were detected: diethyl phthalate (probably coming from the catalyst of PP polymerization, intentionally added substance (IAS)), and glycerine (a marker of non-intentionally added substances (NIAS)).

Cropping sequences and no-till quality indicators in the Middle Plateau of Rio Grande do Sul / Sucessão de cultivos e indicadores da qualidade do plantio direto no Planalto Médio do Rio Grande do Sul

The no-tillage system (SPD) brings together the largest complex of conservation technologies for tropical and subtropical soils, however many producers are partially adopting these precepts, enhancing its degradation. The objective of this work was to evaluate the quality of SPD in a locality, located in the Middle Plateau of Rio Grande do Sul, observing the current situation of soil management and agricultural plots in the region conducted under SPD. Land use monitoring was carried out at Linha Cristal, located in the city of Selbach, RS, as well as the evaluation of agricultural plots that represented the different managements observed there, as well as a native forest as reference. For this, the dry phytomass (DP) and the soil surface coverage rate (CR), the density (Sd), critical density (Bd) and degree of compaction (DC) of the soil were determined, in addiction to soil organic matter (SOM). Statistical analysis consisted of univariate analyzes (mean and standard deviation), while the results between the SOM and Ds levels were also submitted to regression analysis. The cultivated area showed low crop diversity in summer crops, predominating soybean (88.6%). Most of the corn in 2016/17 was destined to silage production (59%). The winter harvests were more diversified, with predominance of wheat, barley, white oats and black oats. The annual average DP added to the soil

O sistema plantio direto (SPD) reúne o maior complexo de tecnologias conservacionistas para solos tropicais e subtropicais, entretanto muitos produtores estão adotando parcialmente estes preceitos, potencializando a degradação do mesmo. O objetivo deste trabalho foi avaliar a qualidade do SPD em uma localidade, localizada no Planalto Médio do Rio Grande do Sul, observando qual a situação atual do manejo do solo e das glebas agrícolas da região conduzidas sob SPD. Foi realizado o monitoramento do uso do solo da localidade de Linha Cristal, situada no município de Selbach, RS, bem como a avaliação de glebas agrícolas que representassem diferentes manejos ali observados, além de uma mata nativa servindo de referência. Para isso, nestas glebas foram determinados os aportes de fitomassa seca (FMS) e o índice de cobertura (IC) da superfície do solo, a densidade (Ds), densidade crítica (Dsc) e grau de compactação (GC) do solo, além dos teores de matéria orgânica do solo (MOS). A análise estatística consistiu em análises univariadas (média e desvio padrão), já os resultados entre os teores de MOS e a Ds, também foram submetidos à análise de regressão. A área cultivada apresentou baixa diversidade de culturas no período de verão, predominando a soja (88,6%). Maior parte do milho em 2016/2017, destinou-se a produção de silagem (59%). Os cultivos de inverno foram mais diversificados
