Exploring Microorganisms from Plastic-Polluted Sites: Unveiling Plastic Degradation and PHA Production Potential.

The exposure of microorganisms to conventional plastics is a relatively recent occurrence, affording limited time for evolutionary adaptation. As part of the EU-funded project BioICEP, this study delves into the plastic degradation potential of microorganisms isolated from sites with prolonged plastic pollution, such as plastic-polluted forests, biopolymer-contaminated soil, oil-contaminated soil, municipal landfill, but also a distinctive soil sample with plastic pieces buried three decades ago. Additionally, samples from Arthropoda species were investigated. In total, 150 strains were isolated and screened for the ability to use plastic-related substrates (Impranil dispersions, polyethylene terephthalate, terephthalic acid, and bis(2-hydroxyethyl) terephthalate). Twenty isolates selected based on their ability to grow on various substrates were identified as Streptomyces, Bacillus, Enterococcus, and Pseudomonas spp. Morphological features were recorded, and the 16S rRNA sequence was employed to construct a phylogenetic tree. Subsequent assessments unveiled that 5 out of the 20 strains displayed the capability to produce polyhydroxyalkanoates, utilizing pre-treated post-consumer PET samples. With Priestia sp. DG69 and Neobacillus sp. DG40 emerging as the most successful producers (4.14% and 3.34% of PHA, respectively), these strains are poised for further utilization in upcycling purposes, laying the foundation for the development of sustainable strategies for plastic waste management.

Evaluation of Solanum linnaeanum and S. sisymbriifolium extracts for the management of Meloidogynechitwoodi.

Meloidogyne chitwoodi causes significant yield losses in many crops and the chemical control measures currently used are less effective for this nematode. The activity of aqueous extracts (0.8 mg/mL) of one-month-old (R1M) and two-months-old roots and immature fruits (F) of Solanum linnaeanum (Sl) and S. sisymbriifolium cv. Sis 6001 (Ss) were tested on hatching, mortality, infectivity and reproduction of M. chitwoodi. The extracts selected reduced the hatching of second-stage juveniles (J2) (cumulative hatching of 40% for Sl R1M and 24% for Ss F) but did not affect J2 mortality. However, infectivity of J2 exposed to the selected extracts, during 4 and 7 days, was lower (3% and 0% for Sl R1M and 0% and 0% for Ss F) compared to the control (23% and 3%). Reproduction was affected only after 7 days of exposure (reproduction factor (RF) was 7 for Sl R1M and 3 for Ss F) compared to the control (RF = 11). The results suggest that the selected Solanum extracts are effective and can be a useful tool in sustainable M. chitwoodi management. This is the first report on the efficacy of S. linnaeanum and S. sisymbriifolium extracts against root-knot nematodes.

Economic and financial model to the mass-rearing of Macrolophus pygmaeus (Rambur) (Heteroptera: Miridae), a biological control agent against the tomato moth Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) in protected culture.

BACKGROUND: Tuta absoluta (Meyrick) is a major pest of tomato produced in glasshouses and open field, causing severe damages to crops, reducing the quality of tomato fruits. The current maintenance of the pest populations below the economic threshold is not achieved by natural and classical control, thus requiring the continuous application of biological control agents (BCAs), under an augmentative or inoculative approach. The present study aims to develop an economic and financial model to evaluate the commercial viability of a continuous mass production of Macrolophus pygmaeus (Rambur), a BCA commonly used against the tomato moth, Tuta absoluta, in protected culture. The estimations for our model were based on two approaches: the farm-level impact analysis and the benefit-cost analysis. RESULTS: The results of the farm-level analysis show that the adoption of a more sustainable biological control approach is profitable for farmers and the benefit-cost analysis provides evidence that the investment on a new factory dedicated to the mass rearing of M. pygmaeus to control tomato moth populations generates a positive net present value (NPV) of 7.2 million euros, corresponding to an internal rate of return (IRR) of 28.4% per year. CONCLUSION: Our results are in line with (i) the more recent European Commission proposals for a new Regulation on sustainable use of plant protection products, which includes the reduction of 50% the use and risk of chemical pesticides by 2030 and (ii) most of the existing literature which conclude that new projects on BCA production are worth investments. © 2023 The Authors.

Knowledge, Perceptions, and Practices on Risks and Disasters Among Medical Students. A Multicenter Cross-Sectional Study in 9 Latin American and Caribbean Countries.

Purpose: The objective of this study was to describe the level of knowledge, perceptions, and practices in relation to risks and disasters in medical schools in Latin America and the Caribbean. Participants and Methods: Multicenter, observational, analytical, non-probabilistic convenience sample study with 2546 medical students in 9 countries of Latin America and the Caribbean. An online survey was conducted between October 2020 and November 2020, using an instrument validated in each country to assess knowledge, perceptions, and practices regarding risk and disaster prevention measures. Frequencies, percentages, mean and standard deviation (SD) were used for descriptive analysis. Differences resulting from the relationship between the variables studied and the level of knowledge were obtained using the Chi-square test. P-value <0.05 was accepted as statistically significant for all analyses. Results: The highest proportion of responses came from women, third-semester students, and those studying in public universities. Students from Colombia and Honduras had the highest percentage of high levels of knowledge about disasters, while Peruvian students had the highest percentage of low levels of knowledge. Women and students from public universities showed a higher proportion of high levels of knowledge. 52.7% considered that they live in a country with a medium risk of natural disasters, while 91.2% said that Latin American and Caribbean countries are not prepared to face natural disasters. Only 43.6% believe they are prepared to help in the event of a natural disaster. Conclusion: Most of medical students from Latin America and Latin America and the Caribbean have high and medium level of knowledge in risks and disasters. However, the implementation of disaster training programs for medical students has the potential to improve the preparedness, knowledge, and skills that are important for medical personnel to improve their self-confidence, and their ability to respond, resulting in more effective systems.

Representaciones sociales del desastre natural para las madres damnificadas de una comunidad urbano-marginal de Lima, Perú / Social Representations of Natural Disasters for Affected Women from an Urban-Marginal Community in Lima, Peru

Introducción: Los desastres naturales generan un impacto negativo en la salud y vida de la población; sin embargo, existen escasos estudios cualitativos que aborden su repercusión en la vida, la salud mental y el imaginario de los afectados. Objetivo: Caracterizar las representaciones sociales del desastre natural que tienen las madres damnificadas del fenómeno del Niño Costero de una comunidad urbano-marginal de Lima, Perú. Métodos: Investigación cualitativa, exploratoria, basada en la metodología de las representaciones sociales. Se realizó en diciembre del 2019, en Lima, Perú. El muestreo fue no probabilístico intencional, debido al acceso al lugar y la disponibilidad hasta llegar al punto de saturación; se entrevistó en profundidad a 11 madres y luego se realizó análisis del discurso. Resultados: Emergieron tres categorías: vivir la vulnerabilidad socioambiental, reconfortarse con un ser divino y enfrentar la crisis ecológica. Conclusiones: Las mujeres damnificadas reconocen la vulnerabilidad socioambiental por su condición socioeconómica precaria y vivir en la ribera del río. Asimismo, no encuentran las estrategias para superar su situación y se refugian en la ayuda y protección de un ser divino; frente al desastre natural tienen conciencia de la crisis ecológica en la que viven y la necesidad de una respuesta integral y colectiva(AU)

Introduction: Natural disasters generate a negative impact on the health and life of the population; however, there are few qualitative studies addressing their impact on the life, mental health and imaginary of those affected. Objective: To characterize the social representations of the natural disaster held by mothers affected by "El Niño Costero" phenomenon in an urban-marginal community of Lima, Peru. Methods: A qualitative and exploratory research, based on the methodology of social representations, was conducted in December 2019, in Lima, Peru. The sampling was intentional nonprobabilistic, due to the access to the place and the availability until reaching the saturation point; in-depth interviews were conducted with 11 mothers and then discourse analysis was performed. Results: Three categories emerged: living the socioenvironmental vulnerability, being comforted by a divine being, and facing the ecological crisis. Conclusions: The affected women recognize their socioenvironmental vulnerability due to their precarious socioeconomic condition and the fact that they live on the riverbank. Likewise, they do not find any strategies for overcoming their situation and take refuge in the help and protection from a divine being instead. In the face of the natural disaster, they are aware of the ecological crisis in which they live and the need for an integral and collective response(AU)

Acanthus mollis Formulations for Transdermal Delivery: From Hydrogels to Emulsions.

Topical formulations of Acanthus mollis L. leaf and the optimization of the release of their active compounds and their topical bioavailability were investigated for the first time. In vitro, the release of active compounds from three formulations-an oil-in-water cream and two hydrogels (Carbopol 940 and Pluronic F-127)-was determined using Franz diffusion cells. Detection and quantification of the compounds was performed via high-performance liquid chromatography with a photodiode array (HPLC-PDA). DIBOA, a bioactive compound of this medicinal plant, exhibited release kinetics of the Weibull model for the Carbopol and Pluronic F-127 formulation, identifying it as a potential active agent to optimize the topical distribution of the formulations. The implications extend to applications in inflammation treatment and tyrosinase inhibition, suggesting that it can make a significant contribution to addressing skin conditions, including melanoma and various inflammatory diseases.

Terapia ocupacional social, gêneros e sexualidades dissidentes: experiências a partir da extensão universitária / Social occupational therapy and dissenting genders and sexualities: experiences from extension projects

Resumo Este artigo trata do relato de experiência do projeto de extensão ResisTO em parceria com uma política pública municipal numa capital do nordeste voltada à população dissidente de gêneros e sexualidades. O relato está organizado em três partes: na primeira parte, o projeto de extensão é apresentado e contextualizado; na segunda parte, discute-se a terapia ocupacional social, seu histórico e a aproximação com as discussões sobre gêneros e sexualidades; a terceira parte contém a trajetória das ações desenvolvidas e as parcerias realizadas ao longo dos seis anos de existência do projeto, elencando e refletindo sobre os principais desafios e a potencialidade do trabalho desenvolvido. O projeto tem se dedicado a ações e reflexões que tomam como base a análise dos marcadores sociais da diferença — em especial, gêneros e sexualidades — e da interseccionalidade. Ancora-se também no referencial teórico-metodológico da terapia ocupacional social e nas políticas públicas voltadas à população LGBTQIAP+. Ao longo dos seis anos de execução do projeto, por meio de diferentes ações, foi possível promover o acesso a um conhecimento democrático problematizando a essencialização das diferenças e desigualdades, buscando formas para uma convivência pautada no respeito e na solidariedade, produzindo estratégias que respondem às necessidades dos sujeitos - individuais e coletivos, visando construir e ampliar os direitos sociais e produzindo reflexões e ações democráticas.

Abstract This study addresses the experience report of the ResisTO university extension project in partnership with a municipal public policy in a state capital in northeastern Brazil aimed at the gender and sexuality dissenting population. The report is organized into three parts: in the first part, the extension project is presented and contextualized; the second part discusses social occupational therapy, its history, and the approach to debates on gender and sexualities; the third part presents the trajectory of the actions developed and the partnerships carried out over the six years of the project's existence, listing and reflecting on the main challenges and the potential of the work developed. The project has been dedicated to actions and reflections that are based on the analysis of social markers of difference—especially, genders and sexualities—and intersectionality. It is also anchored in the theoretical-methodological framework of social occupational therapy and public policies aimed at the LGBTQIAP+ population. Over six years of project execution, through different actions, it was possible to promote access to democratic knowledge questioning the essentialization of differences and inequalities, seek ways of living together based on respect and solidarity, produce strategies that respond to the individual and collective needs of subjects, aiming to build and expand social rights and producing reflections and democratic actions.

Effect of Phenolic Compounds from Cymbopogon citratus (DC) Stapf. Leaves on Micellar Solubility of Cholesterol.

Dyslipidemias are one of the risk factors for cardiovascular diseases, the leading cause of death and hospitalization worldwide. One way to control cholesterol levels is to control the exogenous cholesterol intake in the body. Natural polyphenolic compounds, namely theaflavins from plant extracts such as black tea, showed the ability to inhibit the formation of the micellar structure, essential for the absorption of cholesterol in the intestine. There are several methodologies to determine this effect, many of which are expensive and time-consuming. Due to these facts, the main purposes of this work were to optimize an inexpensive colorimetric method to study, in vitro, the micellar solubility of cholesterol and applied it to plant extracts. In this work, Cymbopogon citratus leaf extracts, its phenolic fractions, and flavonoids were evaluated. The non-delipidified infusion (CcI) obtained a maximum percentage of micelle destruction of 59.22% for a concentration of 50 µg/mL and the delipidified infusion (CcdI) obtained a maximum percentage of micelle destruction of 58.01% for a concentration of 200 µg/mL. In the case of the fraction of phenolic acids (CcPAs), 23.85% of maximum micellar destruction was recorded for the concentration of 100 µg/mL, while for the fraction of flavonoids (CcF), the micellar destruction was 92.74% at 1 µg/mL, and for the tannin fraction (CcT) of 99.45% at 25 µg/mL. Luteolin presented a percentage of micelle destruction of 94.83% in the concentration of 1 ng/mL, followed by luteolin-7-O-glucoside with 93.71% and luteo-lin-6-C-glucoside with 91.26% at the concentrations of 25 ng/mL and 50 ng/mL, respectively. These results suggest the capability of polyphenols from Cymbopogon citratus to prevent the cholesterol absorption in the gut by micellar destruction, and its contribution for cholesterol-lowering activity.

Synergistic Effect of DIBOA and Verbascoside from Acanthus mollis Leaf on Tyrosinase Inhibition.

Overexpression of melanin contributes to darkening of plant and fruit tissues and skin hyperpigmentation, leading to melasma or age spots. Although melanin biosynthesis is complex and involves several steps, a single enzyme known as tyrosinase is key to regulating this process. The melanogenesis pathway is initiated by oxidation of the starting material l-tyrosine (or l-DOPA) to dopaquinone by tyrosinase; the resulting quinone then serves as a substrate for subsequent steps that eventually lead to production of melanin. Medicinal plants are considered a good source of tyrosinase inhibitors. This study investigated the tyrosinase inhibitory activity of A. mollis leaf extracts and their phytochemicals. Significant activity was verified in the ethanol extract -EEt (IC50 = 1.21 µg/mL). Additionally, a kinetic study showed that this tyrosinase inhibition occurs by DIBOA (2,4-dihydroxy-1,4-benzoxazin-3-one) and verbascoside contribution through a non-competitive reaction mechanism. A synergistic effect on tyrosinase inhibition was observed in the binary combination of the compounds. In conclusion, both EEt and a mixture of two of its phytochemicals can be effective tyrosinase inhibitors and can be used as a bleaching agent for cosmetic formulations in the future.

Forest Biomass as a Promising Source of Bioactive Essential Oil and Phenolic Compounds for Alzheimer's Disease Therapy.

Alzheimer's disease (AD) is the most common neurodegenerative disorder affecting elderly people worldwide. Currently, there are no effective treatments for AD able to prevent disease progression, highlighting the urgency of finding new therapeutic strategies to stop or delay this pathology. Several plants exhibit potential as source of safe and multi-target new therapeutic molecules for AD treatment. Meanwhile, Eucalyptus globulus extracts revealed important pharmacological activities, namely antioxidant and anti-inflammatory properties, which can contribute to the reported neuroprotective effects. This review summarizes the chemical composition of essential oil (EO) and phenolic extracts obtained from Eucalyptus globulus leaves, disclosing major compounds and their effects on AD-relevant pathological features, including deposition of amyloid-ß (Aß) in senile plaques and hyperphosphorylated tau in neurofibrillary tangles (NFTs), abnormalities in GABAergic, cholinergic and glutamatergic neurotransmission, inflammation, and oxidative stress. In general, 1,8-cineole is the major compound identified in EO, and ellagic acid, quercetin, and rutin were described as main compounds in phenolic extracts from Eucalyptus globulus leaves. EO and phenolic extracts, and especially their major compounds, were found to prevent several pathological cellular processes and to improve cognitive function in AD animal models. Therefore, Eucalyptus globulus leaves are a relevant source of biological active and safe molecules that could be used as raw material for nutraceuticals and plant-based medicinal products useful for AD prevention and treatment.

A review of the ethnomedicinal uses, chemistry, and pharmacological properties of the genus Acanthus (Acanthaceae).

ETHNOPHARMACOLOGICAL RELEVANCE: The Acanthus genus belongs to the Acanthaceae family, and its species are distributed in all continents, mainly in tropical and subtropical regions. Several traditional applications are referred to, but few scientific studies validate them. Despite this, studies in animal models corroborate some of its uses in folk medicine, such as anticancer, antidiabetic, anti-inflammatory, and antinociceptive, which encourages the research on plants of this genus. AIM OF THE REVIEW: To our knowledge, this document is the first comprehensive review study that provides information on the geographic distribution, botanical characteristics, ethnomedicinal uses, phytochemicals, and pharmacological activities of some Acanthus species to understand the correlation between traditional uses, phytochemical, and pharmacological activities, providing perspectives for future studies. RESULTS: In traditional medicine, Acanthus species are mainly used for diseases of respiratory, nervous and reproductive system, gastrointestinal and urinary tract, and skin illness. The most used species are A. montanus, A. ilicifolius, and A. ebracteatus. Chemical compounds (125) from different chemical classes were isolated and identified in seven species, mainly from A. ilicifolius, about 80, followed by A. ebracteatus and A. montanus, appearing with a slightly lower number with fewer phytochemical profile studies. Isolated phytoconstituents have been mainly alkaloids, phenylpropanoid glycosides, and phenylethanoids. In addition, aliphatic glycosides, flavonoids, lignan glycosides, megastigmane derivatives, triterpenoids, steroids, fatty acids, alcohols, hydroxybenzoic acids, simple phenols were also cited. Scientific studies from Acanthus species extracts and their phytoconstituents support their ethnomedical uses. Antimicrobial activity that is the most studied, followed by the antioxidant, anti-inflammatory, and anticancer properties, underlie many Acanthus species activities. A. dioscoridis, A. ebracteatus, A. hirsutus, A. ilicifolius, A. mollis, A. montanus, and A. polystachyus have studies on these activities, A. ilicifolius being the one with the most publications. Most studies were essentially performed in vitro. However, the anticancer, antidiabetic, anti-inflammatory and antinociceptive properties have been studied in vivo. CONCLUSION: Acanthus species have remarkable phytoconstituents with different biological activities, such as antioxidant, antimicrobial, anti-inflammatory, antinociceptive, hepatoprotective, and leishmanicidal, supporting traditional uses of some species. However, many others remain unexplored. Future studies should focus on these species, especially pharmacological properties, toxicity, and action mechanisms. This review provides a comprehensive report on Acanthus genus plants, evidencing their therapeutic potential and prospects for discovering new safe and effective drugs from Acanthus species.

Analysis of Variables that Influence the Success Rates of Induction of Labor with Misoprostol: A Retrospective Observational Study.

OBJECTIVE: Determine the predictive criteria for success in inducing labor for live fetuses using misoprostol in pregnant women. Secondarily, the objective is to determine the rates of vaginal or cesarean delivery, duration of induction, interval of administration of misoprostol, the main causes of induction of labor and indication for operative delivery. METHODS: Medical records of 873 pregnant women admitted for cervical maturation from January 2017 to December 2018 were reviewed in a descriptive observational study of retrospective analysis, considering the following response variables: age, parity, Bishop Index, doses of misoprostol, labor induction time. Logistic regression models were used to predict success with misoprostol in non-operative deliveries. RESULTS: Of the 873 patients evaluated, 72% evolved with vaginal delivery, 23% of the cases were cesarean, 5% forceps or vacuum-extractor. For non-operative delivery the predictive variables at admission were age, parity, gestational age and dilation. During hospitalization, fewer vaginal touches, amniotomy or amniorrhexis with clear fluid lead to a shorter induction time and a greater chance of non-operative delivery. False positives and false negatives of the model were always below 50% and correct answers above 65%. CONCLUSION: At admission, age less than 24 years, previous normal births, lower the gestational age and greater the dilation, were predictive of greater probability of non-operative delivery. During hospitalization, the less vaginal touches and occurrence of amniotomy/amniorrhexis with clear liquid indicate shorter induction time. Future studies with a prospective design and analysis of other factors are necessary to assess the replicability, generalization of these findings.

OBJETIVO: Determinar os critérios preditivos para o sucesso na indução do trabalho de parto para fetos vivos utilizando misoprostol em gestantes. Em segundo lugar, o objetivo é determinar as taxas de parto vaginal ou cesáreo, duração da indução, intervalo de administração de misoprostol, as principais causas de indução do trabalho de parto e indicação para parto operatório. MéTODOS: Foram revisados os prontuários de 873 gestantes internadas para amadurecimento cervical entre janeiro de 2017 e dezembro de 2018 em um estudo descritivo observacional de análise retrospectiva, considerando as variáveis-resposta: idade, paridade, Índice de Bishop, doses de misoprostol, tempo de indução do trabalho de parto. Modelos de regressão logística foram utilizados para prever o sucesso com misoprostol em partos não operatórios. RESULTADOS: Dos 873 pacientes avaliados, 72% evoluíram com parto vaginal, 23% dos casos foram cesáreos, 5% fórceps ou vácuo-extrator. Para o parto não operatório as variáveis preditivas na internação foram idade, paridade, idade gestacional e dilatação. Durante a internação, um menor número de toques vaginais, amniotomia ou amniorrexe com líquido claro, levam a menor tempo de indução e maior chance de parto não operatório. Falsos positivos e falsos negativos do modelo sempre foram inferiores a 50% e respostas corretas acima de 65%. CONCLUSãO: Na internação, idade menor que 24 anos, ocorrência de partos normais anteriores, menor idade gestacional e maior dilatação, foram preditivos de maior probabilidade de parto não-operatório. Durante a internação, o menor número de toques vaginais, amniotomia/amniorrexe com líquido claro indicam menor tempo de indução. Estudos futuros com design prospectivo e análise de outros fatores são necessários para avaliar a replicabilidade, generalização desses achados.

Objetivo: Investigar o uso de Equipamentos de Proteção Individual no enfrentamento à Covid-19. Métodos: Estudodescritivo e quantitativo realizado através de plataformas digitais, entre agosto e outubro de 2020. A coleta deu-se por meio de formulário com posterior análise estatística pelo Software R. Resultados: A amostra conteve 61 participantes. Houve prevalência de pessoas entre 31 a 40 anos, com nível superior e solteiros. A análise estatística revelou (p<0.05) para uso dos equipamentos: gorro, luva, protetor facial, sapato, óculos e avental na proteção contra a Covid-19. Quanto ao uso destes, 57,4% dos profissionais realizaram procedimentos sem proteção e para 55,7% a quantidade fornecida foi insuficiente. Ainda, 80,3% reutilizaram os insumos na pandemia, sendo que 13,1% se contaminaram pela Covid-19. Conclusão: Os profissionais de saúde apontaram dificuldades para uso de equipamentos de proteção, o que aumentou o risco de contaminação pela Covid-19.

Objective: To investigate the use of Personal Protective Equipment in confronting Covid-19. Methods:Descriptive and quantitative study conducted through digital platforms, between August and October 2020. The collection took place through a form with subsequent statistical analysis by R Software. Results:The sample contained 61 participants. There was a prevalence of people between 31 and 40 years old, with higher education, and single. Statistical analysis revealed (p<0.05) the use of the following equipment: cap, glove, face shield, shoes, goggles, and apron to protect against Covid-19. As for their use, 57.4% of the professionals performed procedures without protection and for 55.7% the amount provided was insufficient. Furthermore, 80.3% reused the supplies during the pandemic,and 13.1% were contaminated by Covid-19. Conclusion:The health care professionals pointed out difficulties in using protective equipment, which increased the risk of contamination by Covid-19.

Chemical Composition and Effect against Skin Alterations of Bioactive Extracts Obtained by the Hydrodistillation of Eucalyptus globulus Leaves.

Eucalyptus globulus is planted extensively for pulp, paper and wood production. Although bioactive compounds obtained from its biomass are used as cosmetics ingredients, the skin effects were not yet fully explored. In order to fill this gap, this work aimed to study the protective effect against skin damage provided by the essential oil (EO) obtained from the hydrodistillation of Eucalyptus globulus leaves, and by an extract obtained from the hydrodistillation residual water (HRW). The major compound identified in the EO was 1,8-Cineole, and the phenolic acids in the HRW included gallic acid as the main phenolic constituent. Moreover, non-toxic EO and HRW concentrations were shown to have anti-aging skin effects in vitro, decreasing age-related senescence markers, namely ß-galactosidase and matrix metalloproteinases activation, as well as collagen type 1 upregulation. In addition, EO and HRW were found to exhibit depigmenting effects by inhibiting tyrosinase and melanin production, along with potent anti-inflammatory properties. Furthermore, the absence of skin irritation and sensitization in cells exposed to EO and HRW revealed the safety of both extracts for topical use. Taken together, these results highlight the beneficial effects of extracts obtained from Eucalyptus globulus biomass for skin aesthetic and health purposes, which should be explored deeply for the prediction of future pharmaceutical and dermocosmetics industrial applications.

Individuals With SARS-CoV-2 Infection During the First and Second Waves in Catalonia, Spain: Retrospective Observational Study Using Daily Updated Data.

BACKGROUND: A description of individuals with SARS-CoV-2 infection comparing the first and second waves could help adapt health services to manage this highly transmissible infection. OBJECTIVE: We aimed to describe the epidemiology of individuals with suspected SARS-CoV-2 infection, and the characteristics of patients with a positive test comparing the first and second waves in Catalonia, Spain. METHODS: This study had 2 stages. First, we analyzed daily updated data on SARS-CoV-2 infection in individuals from Girona (Catalonia). Second, we compared 2 retrospective cohorts of patients with a positive reverse-transcription polymerase chain reaction or rapid antigen test for SARS-CoV-2. The severity of patients with a positive test was defined by their admission to hospital, admission to intermediate respiratory care, admission to the intensive care unit, or death. The first wave was from March 1, 2020, to June 24, 2020, and the second wave was from June 25, 2020, to December 8, 2020. RESULTS: The numbers of tests and cases were lower in the first wave than in the second wave (26,096 tests and 3140 cases in the first wave versus 140,332 tests and 11,800 cases in the second wave), but the percentage of positive results was higher in the first wave than in the second wave (12.0% versus 8.4%). Among individuals with a positive diagnostic test, 818 needed hospitalization in the first wave and 680 in the second; however, the percentage of hospitalized individuals was higher in the first wave than in the second wave (26.1% versus 5.8%). The group that was not admitted to hospital included older people and those with a higher percentage of comorbidities in the first wave, whereas the characteristics of the groups admitted to hospital were more alike. CONCLUSIONS: Screening systems for SARS-CoV-2 infection were scarce during the first wave, but were more adequate during the second wave, reflecting the usefulness of surveillance systems to detect a high number of asymptomatic infected individuals and their contacts, to help control this pandemic. The characteristics of individuals with SARS-CoV-2 infection in the first and second waves differed substantially; individuals in the first wave were older and had a worse health condition.
