RESUMO

Multiple bodies and territories experience impacts, conflicts, and socioenvironmental injustices in different ways. The consequences of the neoextractivist accumulation patterns weigh differently on women, especially non-white women. This text brings narratives of a wide range of women who live in different territories and experience different impacts from major undertakings. Through their narratives, we seek to understand how they constitute their territorial bodies; how they are impacted; and how they resist colonialist domination, defend life, and restore health. These impacts affect women's means and ways of life, and restrict their ways of being, power, and knowledge in these territories, rendering them vulnerable, subject to the precariousness of life, immersed in systemic intoxication, reaching situations classified as genocide. Faced with such threats, they manage collective resistance; trigger what makes them active subjectivity; and decolonize themselves as beings, knowledge, and power. In this way they defend life and restore their health and that of their environments. These experiences indicate ways to strengthen public health surveillance perspectives and networks.

Corpos e territórios múltiplos vivenciam de diferentes formas impactos, conflitos e injustiças socioambientais. As consequências do padrão de acumulação neoextrativista recai de modo diferenciado sobre as mulheres, em especial não brancas. Esse texto traz narrativas de mulheres plurais, que vivem em diferentes territórios e que experienciam distintos impactos de grandes empreendimentos. Por meio de suas narrativas, buscamos compreender como constituem seus corpos-territórios, como são impactados e como resistem a dominação colonialista, defendem a vida e restituem a saúde. Os impactos analisados atingem os meios e modos de vida das mulheres, cerceiam suas formas de ser, poder e saber nesses territórios, tornam-nas vulnerabilizadas, sujeitas à precarização dos meios e modos de vida, imersas em intoxicações sistêmicas, chegando a situações classificadas como genocídios. Frente a tais ameaças, elas agenciam a resistência coletiva, acionam o que lhes torna subjetividade ativa, descolonizam-se como ser, saber e poder. Assim defendem a vida e restituem a saúde de si mesmas e de seus ambientes. Essas experiências apontam caminhos para o fortalecimento de perspectivas e redes de vigilância popular em saúde.

RESUMO

OBJECTIVE: To describe the discrimination experienced by the general female surgeon. METHOD: Prospective, cross-sectional and descriptive study, with a survey of 30 questions, closed, anonymous, voluntary and confidential, distributed through a link in the WhatsApp chat in a closed group of female surgeons who are members of the Asociación Mexicana de Cirugía General. RESULTS: 146 female surgeons participated, with a response rate of 58.4%. The discrimination perceived by female surgeons in training was 86 (58.9%), and 28 (19.2%) when they are already surgeons by not allowing them to perform the same procedures as their peers. Regarding the patients, discrimination against female surgeons was 72 (49.3%). They do not call them doctors, but "ladies", in 126 (86.3%), and they are asked to perform nursing duties in 120 (82.2%). On the other hand, there is also discrimination against female surgeons by nursing staff in 87 (59.6%). CONCLUSIONS: Discrimination is common in the daily surgical practice of female surgeons in all three areas: peers, patients, and nursing staff. This is an initial work, where the quantification of discrimination in Mexico is carried out. Strategies must be implemented to avoid discrimination against female surgeons and be in an environment of equality.

OBJETIVO: Describir la discriminación que vive la cirujana general en México. MÉTODO: Estudio prospectivo, transversal y descriptivo, con una encuesta de 30 preguntas cerradas, de manera anónima, voluntaria y confidencial, distribuida a través de un enlace en el chat de WhatsApp en un grupo cerrado de cirujanas de todo el país que son miembros de la Asociación Mexicana de Cirugía General. RESULTADOS: Participaron 146 cirujanas, con un porcentaje de respuesta del 58.4%. La discriminación percibida por las cirujanas en formación fue de 86 (58.9%), frente a 28 (19.2%) cuando ya son cirujanas, al no permitirles realizar los mismos procedimientos que sus pares. La discriminación por parte de los pacientes fue de 72 (49.3%). No las llaman doctoras sino «señoritas¼ en 126 (86.3%) y les solicitan hacer funciones de enfermería en 120 (82.2%). También existe discriminación hacia las cirujanas por el personal de enfermería en 87 (59.6%). CONCLUSIONES: La discriminación hacia las cirujanas es frecuente en los tres ámbitos: pares, pacientes y personal de enfermería. Este es un trabajo inicial, donde se realiza la cuantificación de la discriminación en México. Se deberán implementar las estrategias para evitar la discriminación a las cirujanas y estar en un ambiente de igualdad.

RESUMO

Endometriosis is characterized by the growth of endometrial-like tissue outside the uterus, and it is associated with alterations in the expression of hormone receptors and inflammation. Estetrol (E4) is a weak estrogen that recently has been approved for contraception. We evaluated the effect of E4 on the growth of endometriotic-like lesions and the expression of TNF-α, estrogen receptors (ERs), and progesterone receptors (PRs) in an in vivo murine model. Endometriosis was induced surgically in female C57BL/6 mice. E4 was delivered via Alzet pump (3 mg/kg/day) from the 15th postoperative day for 4 weeks. E4 significantly reduced the volume (p < 0.001) and weight (p < 0.05) of ectopic lesions. Histologically, E4 did not affect cell proliferation (PCNA immunohistochemistry) but it did increase cell apoptosis (TUNEL assay) (p < 0.05). Furthermore, it modulated oxidative stress (SOD, CAT, and GPX activity, p < 0.05) and increased lipid peroxidation (TBARS/MDA, p < 0.01). Molecular analysis showed mRNA (RT-qPCR) and protein (ELISA) expression of TNF-α decreased (p < 0.05) and mRNA expression of Esr2 reduced (p < 0.05), in contrast with the increased expression of Esr1 (p < 0.01) and Pgr (p < 0.05). The present study demonstrates for the first time that E4 limited the development and progression of endometriosis in vivo.

RESUMO

Bioactive compounds from medicinal plants have applications in the development of functional foods. However, since they are unstable, encapsulation is used as a conservation alternative. This work aimed to assess the bioactive properties (antioxidant and hypoglycemic) of different extracts, including the infusion, as well as their spray-dried microencapsulates from Tecoma stans leaves. A factorial design was proposed to determine the best extraction conditions, based on ABTS and DPPH inhibition. Maltodextrin (MD), arabic gum (AG), and a 1:1 blend (MD:AG) were used as encapsulating agents. Moreover, characterization through physicochemical properties, gas chromatography/mass spectrometry (GC-MS) and scanning electron microscopy (SEM) of the best two powders based on the bioactive properties were analyzed. The results showed that the combination of stirring, water, and 5 min provided the highest inhibition to ABTS and DPPH (35.64 ± 1.25 mg Trolox/g d.s. and 2.77 ± 0.01 g Trolox/g d.s., respectively). Spray drying decreased the antioxidant activity of the extract while preserving it in the infusion. The encapsulated infusion with MD:AG had the highest hypoglycemic activity as it presented the lowest glycemic index (GI = 47). According to the results, the microencapsulates could potentially be added in foods to enhance nutritional quality and prevent/treat ailments.

Objetivos: Caracterizar la diversidad genética de aislamientos virales cubanos en el periodo comprendido entre junio de 2020 y diciembre de 2022. Métodos: Se obtuvo el ARN de SARS-CoV-2 de 27 aislamientos a partir de sobrenadante de cultivo celular y se secuenció el gen S. Las secuencias generadas se emplearon para la identificación y posterior caracterización molecular de las variantes genéticas del virus mediante análisis filogenético y el uso de las herramientas disponibles en la base de datos GISEAD. Resultados: Las variantes detectadas en los aislamientos cubanos de SARS-CoV-2 estudiados se correspondieron a las identificadas en los estudios de vigilancia genómica realizados en las diferentes etapas pandémicas de la COVID-19 en Cuba. El 33,3 % de los aislamientos secuenciados correspondieron a los diferentes linajes de la variante Ómicron, seguido de la variante Beta B 1.351 (29,6 %), otros linajes de SARS-CoV-2 (25,9 %), Alfa B 1.1.7 (7,4 %) y Delta B.1.575 (3,7 %). Se detectó la mutación D614G en todos los aislamientos de SARS-CoV-2 estudiados. Conclusiones: La caracterización molecular de los aislamientos cubanos de SARS-CoV-2 tiene una elevada diversidad genética. Posibilita evaluar in vitro e in vivo los candidatos vacunales y agentes terapéuticos desarrollados por la industria biofarmacéutica cubana.

Introduction: The development of safe and effective vaccines against SARS-CoV-2 posed a huge challenge to face the COVID-19 pandemic. The appearance of new variants of SARS-CoV-2 represents a challenge in evaluating the effectiveness of vaccines, different vaccine and therapeutic candidates developed by the scientific community. Objectives: Characterize and analyze the genetic diversity of Cuban viral isolates, in the period between June 2020 and December 2022. Methods: SARS-CoV-2 RNA was obtained from 27 isolates from cell culture supernatant and the S gene was sequenced. The generated sequences were used for the identification and subsequent molecular characterization of the genetic variants of the virus through phylogenetic analysis and the use of the tools available in the GISEAD database. Results: The variants detected in the Cuban SARS-CoV-2 isolates corresponded to those identified in the genomic surveillance studies carried out in the different stages of the COVID-19 pandemic in Cuba. 33.3% of the sequenced isolates corresponded to the different lineages of the Omicron variant, followed by Beta B 1.351 (29.6%), other SARS-CoV-2 lineages (25.9%), Alpha B 1.1.7 (7.4%) and Delta B.1.575 (3.7%). The D614G mutation was detected in all SARS-CoV-2 isolates studied. Conclusions: The molecular characterization of the Cuban isolates of SARS-CoV-2 has a high genetic diversity. It makes it possible to evaluate in vitro and in vivo vaccine candidates and therapeutic agents developed by the Cuban biopharmaceutical industry.

RESUMO

The aims of this study are to characterize the antiplatelet activity of StSBTc-3, a potato serine protease with fibrino (geno) lytic activity, and to provide information on its mechanism of action. The results obtained show that StSBTc-3 inhibits clot retraction and prevents platelet aggregation induced by thrombin, convulxin, and A23187. Platelet aggregation inhibition occurs in a dose-dependent manner and is not affected by inactivation of StSBTc-3 with the inhibitor of serine proteases phenylmethylsulfonyl fluoride (PMSF). In addition, StSBTc-3 reduces fibrinogen binding onto platelets. In-silico calculations show a high binding affinity between StSBTc-3 and human α2bß3 integrin suggesting that the antiplatelet activity of StSBTc-3 could be associated with the fibronectin type III domain present in its amino acid sequence. Binding experiments show that StSBTc-3 binds to α2bß3 preventing the interaction between α2bß3 and fibrinogen and, consequently, inhibiting platelet aggregation. StSBTc-3 represents a promising compound to be considered as an alternative to commercially available drugs used in cardiovascular therapies.

RESUMO

Community-based psychosocial interventions are key elements of mental health and psychosocial support; yet evidence regarding their effectiveness and implementation in humanitarian settings is limited. This study aimed to assess the appropriateness, acceptability, feasibility and safety of conducting a cluster randomized trial evaluating two versions of a group psychosocial intervention. Nine community clusters in Ecuador and Panamá were randomized to receive the standard version of the Entre Nosotras intervention, a community-based group psychosocial intervention co-designed with community members, or an enhanced version of Entre Nosotras that integrated a stress management component. In a sample of 225 refugees, migrants and host community women, we found that both versions were safe, acceptable and appropriate. Training lay facilitators to deliver the intervention was feasible. Challenges included slow recruitment related to delays caused by the COVID-19 pandemic, high attrition due to population mobility and other competing priorities, and mixed psychometric performance of psychosocial outcome measures. Although the intervention appeared promising, a definitive cluster randomized comparative effectiveness trial requires further adaptations to the research protocol. Within this pilot study we identified strategies to overcome these challenges that may inform adaptations. This comparative effectiveness design may be a model for identifying effective components of psychosocial interventions.

RESUMO

OBJECTIVE: To bring up which was the surgical resident's perception about their learning experience during COVID-19 pandemic and if it interfered or not with their classes. METHOD: Cross-sectional observational study through an anonymous survey conducted among surgical residents. The Mexican Association of General Surgery, through its Women in Surgery Committee, created a questionnaire that included 40 questions. RESULTS: 465 participants were included in the survey: 225 women (48.3%), 240 men (51.7%); of 32 entities, only 26 participated. A great part of them said their skills and abilities were affected because elective surgeries were called off. While 303 residents stayed at hybrid hospitals, while a third of them were at 100% Covid facilities. Residents who were on call worked at COVID-19 units. They continued attending class through online platforms and only 134 were able to practice their skills using simulators. 71% of the residents were infected with COVID-19, all were tested to confirm it, and the number of asymptomatic cases was unknown. CONCLUSIONS: COVID-19 pandemic has affected the learning process of surgical residents in Mexico.

RESUMO

BACKGROUND: In recent years, the rising global demand for cheese, the high cost and limited supply of calf rennet, and consumer choices have increased research into new alternatives to animal or recombinant chymosins for cheese making. Plant proteases with caseinolytic activity (CA) and milk-clotting activity (MCA) have been proposed as alternatives for milk clotting to obtain artisanal cheeses with new organoleptic properties. They have been named vegetable rennets (vrennets). The aim of this study was to evaluate the performance of two Solanum tuberosum aspartic proteases (StAP1 and StAP3) as vrennets for cheese making and to obtain a statistical model that could predict and optimize their enzymatic activity. RESULTS: To optimize the CA and MCA activities, a response surface methodology was used. Maximum values of CA and MCA for both enzymes were found at pH 5.0 and 30-35 °C. Analysis of the degradation of casein subunits showed that it is possible to tune the specificity of both enzymes by changing the pH. At pH 6.5, the αS - and ß- subunit degradation is reduced while conserving a significant MCA. CONCLUSION: The statistical models obtained in this work showed that StAP1 and StAP3 exert CA and MCA under pH and temperature conditions compatible with those used for cheese making. The casein subunit degradation percentages obtained also allowed us to select the best conditions for the degradation of the κ-casein subunit by StAPs. These results suggest that StAP1 and StAP3 are good candidates as vrennets for artisan cheese making. © 2023 Society of Chemical Industry.

RESUMO

BACKGROUND: SOBERANA 02 has been evaluated in phase I and IIa studies comparing homologous versus heterologous schedule (this one, including SOBERANA Plus). Here, we report results of immunogenicity, safety, and reactogenicity of SOBERANA 02 in a two- or three-dose heterologous scheme in adults. METHOD: Phase IIb was a parallel, multicenter, adaptive, double-blind, randomized, and placebo-controlled trial. Subjects (n = 810) aged 19-80 years were randomized to receive two doses of SARS-CoV-2 RBD conjugated to tetanus toxoid (SOBERANA 02) and a third dose of dimeric RBD (SOBERANA Plus) 28 days apart; two production batches of active ingredients of SOBERANA 02 were evaluated. Primary outcome was the percentage of seroconverted subjects with ≥4-fold the anti-RBD immunoglobulin G (IgG) concentration. Secondary outcomes were safety, reactogenicity, and neutralizing antibodies. FINDINGS: Seroconversion rate in vaccinees was 76.3% after two doses and 96.8% after the third dose of SOBERANA Plus (7.3% in the placebo group). Neutralizing IgG antibodies were detected against D614G and variants of concern (VOCs) Alpha, Beta, Delta, and Omicron. Specific, functional antibodies were detected 7-8 months after the third dose. The frequency of serious adverse events (AEs) associated with vaccination was very low (0.1%). Local pain was the most frequent AE. CONCLUSIONS: Two doses of SOBERANA 02 were safe and immunogenic in adults. The heterologous combination with SOBERANA Plus increased neutralizing antibodies, detectable 7-8 months after the third dose.

RESUMO

BACKGROUND: Community- and strengths-based psychosocial interventions are central to mental health and psychosocial support guidelines, but rigorous evidence regarding the effectiveness of these interventions is limited. The complexity and variability that is inherent to many community-based psychosocial interventions requires innovative strategies in order to facilitate the comparability and synthesis across research studies without compromising the fit and appropriateness of interventions to specific study populations and context. Entre Nosotras is a community-based psychosocial intervention developed for migrant and host community women that is designed to be flexible enough to enable integration of external intervention components and adaptable to diverse study contexts and populations. This protocol describes a study that aims to evaluate the appropriateness, acceptability, and feasibility of integrating a standardized stress management intervention into Entre Nosotras. METHODS: This study will evaluate the appropriateness, acceptability, feasibility, and safety of intervention and research procedures for a cluster randomized comparative effectiveness trial conducted in Ecuador and Panamá with migrant and host community women. In this feasibility trial, we will allocate communities nested within the three study sites to the integrated Entre Nosotras + stress management intervention versus Entre Nosotras alone through stratified randomization. Migrant and host community women residing in these study communities who report low to moderate levels of distress will be allocated to the intervention condition that their community is assigned (n = 220 total). We will collect quantitative measures of psychosocial wellbeing, psychological distress, coping, social support, and functioning from study participants. We will collect quantitative measures of fidelity and facilitator competencies through observation and facilitator self-assessment. Data on appropriateness, acceptability, feasibility, and safety will be gathered from participants and facilitators through quantitative assessments at 0, 5, and 10 weeks post-enrollment and qualitative interviews conducted with all facilitators and a subset of 70 study participants during the post-intervention follow-up period. DISCUSSION: Results from this feasibility trial will determine whether a multi-site cluster randomized comparative effectiveness trial of an adaptable community-based psychosocial intervention for migrant and host community women is relevant, acceptable, and feasible.

RESUMO

BACKGROUND: SOBERANA 02 is a COVID-19 vaccine based on SARS-CoV-2 recombinant RBD conjugated to tetanus toxoid (TT). SOBERANA Plus antigen is dimeric-RBD. Here we report safety and immunogenicity from phase I and IIa clinical trials using two-doses of SOBERANA 02 and three-doses (homologous) or heterologous (with SOBERANA Plus) protocols. METHOD: We performed an open-label, sequential and adaptive phase I to evaluate safety and explore the immunogenicity of SOBERANA 02 in two formulations (15 or 25 µg RBD-conjugated to 20 µg of TT) in 40 subjects, 19-59-years-old. Phase IIa was open-label including 100 volunteers 19-80-years, receiving two doses of SOBERANA 02-25 µg. In both trials, half of volunteers were selected to receive a third dose of the corresponding SOBERANA 02 and half received a heterologous dose of SOBERANA Plus. Primary outcome was safety. The secondary outcome was immunogenicity evaluated by anti-RBD IgG ELISA, molecular neutralization of RBD:hACE2 interaction, live-virus-neutralization and specific T-cells response. RESULTS: The most frequent adverse event (AE) was local pain, other AEs had frequencies ≤ 5%. No serious related-AEs were reported. Phase IIa confirmed the safety in 60 to 80-years-old subjects. In phase-I SOBERANA 02-25 µg elicited higher immune response than SOBERANA 02-15 µg and progressed to phase IIa. Phase IIa results confirmed the immunogenicity of SOBERANA 02-25 µg even in 60-80-years. Two doses of SOBERANA02-25 µg elicited an immune response similar to that of the Cuban Convalescent Serum Panel and it was higher after the homologous and heterologous third doses. The heterologous scheme showed a higher immunological response. Anti-RBD IgG neutralized the delta variant in molecular assay, with a 2.5-fold reduction compared to D614G neutralization. CONCLUSIONS: SOBERANA 02 was safe and immunogenic in persons aged 19-80 years, eliciting neutralizing antibodies and specific T-cell response. Highest immune responses were obtained in the heterologous three doses protocol. TRIAL REGISTRY: https://rpcec.sld.cu/trials/RPCEC00000340, https://rpcec.sld.cu/trials/RPCEC00000347.

RESUMO

Aspartic proteases are proteolytic enzymes widely distributed in living organisms and viruses. Although they have been extensively studied in many plant species, they are poorly described in potatoes. The present study aimed to identify and characterize S. tuberosum aspartic proteases. Gene structure, chromosome and protein domain organization, phylogeny, and subcellular predicted localization were analyzed and integrated with RNAseq data from different tissues, organs, and conditions focused on abiotic stress. Sixty-two aspartic protease genes were retrieved from the potato genome, distributed in 12 chromosomes. A high number of intronless genes and segmental and tandem duplications were detected. Phylogenetic analysis revealed eight StAP groups, named from StAPI to StAPVIII, that were differentiated into typical (StAPI), nucellin-like (StAPIIIa), and atypical aspartic proteases (StAPII, StAPIIIb to StAPVIII). RNAseq data analyses showed that gene expression was consistent with the presence of cis-acting regulatory elements on StAP promoter regions related to water deficit. The study presents the first identification and characterization of 62 aspartic protease genes and proteins on the potato genome and provides the baseline material for functional gene determinations and potato breeding programs, including gene editing mediated by CRISPR.

RESUMO

BACKGROUND: The Receptor Binding Domain (RBD) of the SARS-CoV-2 spike protein is the target for many COVID-19 vaccines. Here we report results for phase I clinical trial of two COVID-19 vaccine candidates based on recombinant dimeric RBD (d-RBD). METHODS: We performed a randomized, double-blind, phase I clinical trial in the National Centre of Toxicology in Havana. Sixty Cuban volunteers aged 19-59 years were randomized into three groups (20 subjects each): 1) FINLAY-FR-1 (50 µg d-RBD plus outer membrane vesicles from N. meningitidis); 2) FINLAY-FR-1A-50 (50 µg d-RBD, three doses); 3) FINLAY-FR-1A-25 (25 µg d-RDB, three doses). The FINLAY-FR-1 group was randomly divided to receive a third dose of the same vaccine candidate (homologous schedule) or FINLAY-FR-1A-50 (heterologous schedule). The primary outcomes were safety and reactogenicity. The secondary outcome was vaccine immunogenicity. Humoral response at baseline and following each vaccination was evaluated using live-virus neutralization test, anti-RBD IgG ELISA and in-vitro neutralization test of RBD:hACE2 interaction. RESULTS: Most adverse events were of mild intensity (63.5%), solicited (58.8%), and local (61.8%); 69.4% with causal association with vaccination. Serious adverse events were not found. The FINLAY-FR-1 group reported more subjects with adverse events than the other two groups. After the third dose, anti-RBD seroconversion was 100%, 94.4% and 90% for the FINLAY-FR-1, FINLAY-FR-1A-50 and FINLAY-FR-1A-25 respectively. The in-vitro inhibition of RBD:hACE2 interaction increased after the second dose in all formulations. The geometric mean neutralizing titres after the third dose rose significantly in the group vaccinated with FINLAY-FR-1 with respect to the other formulations and the COVID-19 Convalescent Serum Panel. No differences were found between FINLAY-FR-1 homologous or heterologous schedules. CONCLUSIONS: Vaccine candidates were safe and immunogenic, and induced live-virus neutralizing antibodies against SARS-CoV-2. The highest values were obtained when outer membrane vesicles were used as adjuvant. TRIAL REGISTRY: https://rpcec.sld.cu/en/trials/RPCEC00000338-En.

RESUMO

There is increasing evidence supporting the effectiveness of scalable mental health and psychosocial support (MHPSS) interventions delivered by non-specialists for improving wellbeing among migrant populations in humanitarian settings. Balancing fidelity in the implementation of evidence-based MHPSS interventions with their fit to the needs and preferences of new populations and contexts remains a challenge when introducing MHPSS interventions in new settings. This paper describes a community-based participatory approach to MHPSS intervention design incorporating processes to promote local adaptability and fit while maintaining standardized elements of existing MHPSS interventions. We conducted a mixed-methods study to design a community-based MHPSS intervention that fit the mental health and psychosocial needs of migrant women in three sites in Ecuador and Panama. Drawing from a set of community-based participatory research methods, we identified the priority mental health and psychosocial needs among migrant women, co-developed intervention mechanisms that aligned with those needs, matched mechanisms to existing psychosocial intervention components, and iteratively piloted and refined the intervention with community stakeholders. The resulting intervention was a five-session, lay facilitator-delivered group intervention titled, Entre Nosotras ('among/between us'). The intervention combined elements of individual and community problem solving, psychoeducation, stress management, and social support mobilization to address prioritized problems including psychological distress, safety, community connectedness, xenophobia and discrimination, and social support. This research outlines an emphasis on the social dimension of psychosocial support, as well as a process for balancing fit and fidelity in intervention design and implementation.

RESUMO

Ultrasound is a useful alternative to thermal processing that can be applied to many food products and juices to aid with enzymes and microorganism inactivation and to improve the efficiency of unit operations generally applied in the food industry. The aim of this study was to evaluate the effect of a high-intensity sonication treatment (frequency 20 kHz; intensity 39.4 W/cm2) applied for treatment times from 0 to 105 min on the content of polyphenols, vitamin C, organic acids, and carotenoids, and on the hydrophilic and lipophilic antioxidant capacity and color of orange juice. Treatments were performed in triplicate and data was statistically analyzed. Sonication time did not have a significant effect (P > 0.05) on total polyphenols, total vitamin C, organic acid, and carotenoid contents, lipophilic antioxidant capacity, or juice color. The hydrophilic antioxidant activity and the lutein content increased significantly (P < 0.05) with increased sonication time. These results may be useful as a baseline for the development of sonication treatments that could be used in combination with other traditional and emerging processing approaches to protect the most important bioactive compounds and quality properties of orange juice.

RESUMO

Introducción. La infección por SARS CoV-2 se caracteriza por una afección multisistémica que en la etapa aguda impacta de forma negativa la funcionalidad de los pacientes. Aunque en otros países existen programas de rehabilitación para tratar pacientes con COVID-19, los cuales se basan en la prevención y manejo de complica-ciones agudas, en Colombia existen pocos datos respecto a la epidemiología de esta población. Objetivos. Describir las intervenciones médicas y de rehabilitación que se ofrecieron a los pacientes adultos con COVID-19 que requirieron manejo intrahospitalario en la Clínica Universidad de La Sabana de Chía, Colombia, y definir las características sociodemográficas de esta población. Métodos. Se realizó un análisis descriptivo de las variables establecidas a través de la revisión de las historias clínicas de 96 pacientes atendidos entre julio y diciembre del 2020 en la Clínica Universidad de La Sabana. Resultados. La mayoría de los pacientes eran hombres (62,5%) y la comorbilidad más prevalente fue la hipertensión arterial (47,9%). De los pacientes que tuvieron que ingresarse a la unidad de cuidados intensivos (UCI), 45% requirieron soporte ventilatorio invasivo. La valoración por fisiatría se realizó en promedio a los 9,29 días desde el inicio de hospitalización y el 95,8% de los pacientes recibieron intervención por alguna modalidad terapéutica Conclusiones. Se encontró una alta prevalencia de pacientes masculinos adultos mayores con comorbilidades y procedentes de Chía. En cuanto a la intervención integral de rehabilitación, fisioterapia fue la más prescrita en un 79,5% de la población y el diagnostico más frecuente fue síndrome de desacondicionamiento físico.

Objectives. To describe the medical and rehabilitation interventions offered to adult patients with COVID-19 who required in-hospital management at the Clínica Universidad de La Sabana in Chía, Colombia, and to define the sociodemographic characteristics of this population. Methods. A descriptive analysis of the variables established through the review of the medical records of 96 patients attended between July and December 2020 at the Clínica Universidad de La Sabana was performed. Results. Most patients were men (62.5%) and the most prevalent comorbidity was arterial hypertension (47.9%). Of the patients who had to be admitted to the intensive care unit (ICU), 45% required invasive ventilatory support. Physiatry assessment was performed on average 9.29 days after hospitalization and 95.8% of the patients received intervention by some therapeutic modality. Conclusions. A high prevalence of older male patients with comorbidities and from Chía was found. Regarding the integral rehabilitation intervention, physiotherapy was the most prescribed in 79.5% of the population and the most frequent diangosto was physical deconditioning syndrome.

RESUMO

Plants are sessile organisms that, to survive they develop response mechanisms under water deficit conditions. Plant proteases play an essential role in a diversity of biological processes, among them tolerance to drought stress. Proteolysis is a critical regulator of stomatal development. Plant proteases are involved in the crosstalk among phytohormones and adjustment of stomatal aperture. Plant proteases are also related to the increment in reactive oxygen species (ROS) production detected in the plant biochemical response to drought. Plant proteases mitigate this process by degrading damaged, denatured, and aggregated proteins, remobilizing amino acids, and generating molecules involved in signal transductions. Although many roles for proteases have been proposed, molecular bases that regulate these mechanisms remain unknown. In this review, we summarize the current knowledge on the participation of proteases in the signaling pathways of plants in response to water deficit and their relationship with plant stress tolerance.
