Use of electronic health records and primary health care accessibility according to data from the third cycle of the PMAQ-AB. / Uso de prontuário eletrônico e parâmetros de acesso e acolhimento segundo dados do terceiro ciclo do PMAQ-AB.

The use of electronic health records (EHR) in primary healthcare (PHC) aims for better integration of services and care quality. One of most the critical points of Brazilian PHC is access. This article aims to analyze, through data from the third evaluation cycle of the Brazilian Program for Improving Access and Quality of Primary Care (PMAQ-AB), the relationship between the use of electronic health records and the parameters of access of the participant teams. Cross-sectional analytical study with secondary data. Data from 38,865 primary care teams, 30,346 health units and 140,444 interviewed users were evaluated. The use of EHR was associated with greater care for non-programmed demands (OR 1.664; 95%CI 1.485-1.866), risk and vulnerability assessment (OR 1.329; 95%CI 1.122-1.574) and use of protocols for clinical conducts (OR 1.656; 95%CI 1.530-1.793), in addition to a greater possibility of scheduling consultation by telephone (OR 3.179; 95%CI 3.030-3.335). Services using EHR are more likely to be the patients first contact (OR 1.226; 95%CI 1.171-1.283) and to be sought when facing urgent health problem (OR 1.198; 95%CI 1.161-1.236).

Tic-Tac: A Translational Approach in Mechanisms Associated with Irregular Heartbeat and Sinus Rhythm Restoration in Atrial Fibrillation Patients.

Atrial fibrillation (AF) is a prevalent cardiac condition predominantly affecting older adults, characterized by irregular heartbeat rhythm. The condition often leads to significant disability and increased mortality rates. Traditionally, two therapeutic strategies have been employed for its treatment: heart rate control and rhythm control. Recent clinical studies have emphasized the critical role of early restoration of sinus rhythm in improving patient outcomes. The persistence of the irregular rhythm allows for the progression and structural remodeling of the atria, eventually leading to irreversible stages, as observed clinically when AF becomes permanent. Cardioversion to sinus rhythm alters this progression pattern through mechanisms that are still being studied. In this review, we provide an in-depth analysis of the pathophysiological mechanisms responsible for maintaining AF and how they are modified during sinus rhythm restoration using existing therapeutic strategies at different stages of clinical investigation. Moreover, we explore potential future therapeutic approaches, including the promising prospect of gene therapy.

Natural Trypanosoma cruzi Infection and Climatic Season Influence the Developmental Capacity in Field-Caught Mepraia spinolai Nymphs.

In this study, we evaluated the effect of the climatic season and infection by Trypanosoma cruzi, etiological agent of Chagas disease, on the molting capacity of the triatomine vector Mepraia spinolai endemic to Chile. We used wild-caught first-to-fourth instar nymphs during cooling (fall and winter) and warming (spring) periods. After capturing, nymphs were fed at the laboratory, and maintained under optimal rearing conditions. Feeding was repeated 40 days later. We followed-up the molting events on 709 nymphs, recording one, two or the absence of molts after two feeding opportunities. Within the same climatic period, only infected second- and fourth-instar nymphs from the warming period showed a larger proportion of double molting compared to uninfected nymphs. Regarding the climatic period, infected and uninfected first- and fourth-instar nymphs exhibited a larger proportion of double molting in the warming and cooling periods, respectively. The pattern of non-molting nymph occurrence suggests they probably reach diapause by environmental stochasticity. The effect of the climatic period and T. cruzi infection on the development of M. spinolai is an instar-dependent phenomenon, highlighting the occurrence of finely synchronized processes at different moments of the life cycle of such an hemimetabolous insect as triatomines.

Endostatin and Cancer Therapy: A Novel Potential Alternative to Anti-VEGF Monoclonal Antibodies.

Angiogenesis is a physiological process that consists of the formation of new blood vessels from preexisting ones. Angiogenesis helps in growth, development, and wound healing through the formation of granulation tissue. However, this physiological process has also been linked to tumor growth and metastasis formation. Indeed, angiogenesis has to be considered as a fundamental step to the evolution of benign tumors into malignant neoplasms. The main mediator of angiogenesis is vascular endothelial growth factor (VEGF), which is overexpressed in certain cancers. Thus, there are anti-VEGF monoclonal antibodies, such as bevacizumab, used as anti-cancer therapies. However, bevacizumab has shown adverse events, such as hypertension and proteinuria, which in the most severe cases can lead to cessation of therapy, thus contributing to worsening patients' prognosis. On the other hand, endostatin is an endogenous protein that strongly inhibits VEGF expression and angiogenesis and shows a better safety profile. Moreover, endostatin has already given promising results on small scale clinical studies. Hence, in this review, we present data supporting the use of endostatin as a replacement for anti-VEGF monoclonal antibodies.

High Plasma Levels of Fibroblast Growth Factor 23 Are Associated with Increased Risk of COVID-19 in End-Stage Renal Disease Patients on Hemodialysis: Results of a Prospective Cohort.

End-stage renal disease (ESRD) patients are a population with high rates of COVID-19 and mortality. These patients present a low response to anti-SARS-CoV-2 immunization, which is associated with immune dysfunction. ESRD patients also present high plasma titers of Fibroblast Growth Factor 23 (FGF23), a protein hormone that reduces immune response in vivo and in vitro. Increased FGF23 levels associate with higher infection-related hospitalizations and adverse infectious outcomes. Thus, we evaluated whether ESRD patients with high FGF23 titers have an increased rate of SARS-CoV-2 infection. METHODS: We performed a prospective cohort of ESRD patients in hemodialysis who had measurements of plasma intact FGF23 in 2019. We determined COVID-19 infections, hospitalizations, and mortality between January 2020 and December 2021. RESULTS: We evaluated 243 patients. Age: 60.4 ± 10.8 years. Female: 120 (49.3%), diabetes: 110 (45.2%). During follow-up, 45 patients developed COVID-19 (18.5%), 35 patients were hospitalized, and 12 patients died (mortality rate: 26.6%). We found that patients with higher FGF23 levels (defined as equal or above median) had a higher rate of SARS-CoV-2 infection versus those with lower levels (18.8% versus 9.9%; Hazard ratio: 1.92 [1.03-3.56], p = 0.039). Multivariate analysis showed that increased plasma FGF23 was independently associated with SARS-CoV-2 infection and severe COVID-19. DISCUSSION: Our results suggest that high plasma FGF23 levels are a risk factor for developing COVID-19 in ESRD patients. These data support the potential immunosuppressive effects of high circulating FGF23 as a factor implicated in the association with worse clinical outcomes. Further data are needed to confirm this hypothesis.

Antioxidant Protection against Trastuzumab Cardiotoxicity in Breast Cancer Therapy.

Breast cancer is the most frequent malignant neoplastic disease in women, with an estimated 2.3 million cases in 2020 worldwide. Its treatment depends on characteristics of the patient and the tumor. In the latter, characteristics include cell type and morphology, anatomical location, and immunophenotype. Concerning this latter aspect, the overexpression of the HER2 receptor, expressed in 15-25% of tumors, is associated with greater aggressiveness and worse prognosis. In recent times some monoclonal antibodies have been developed in order to target HER2 receptor overexpression. Trastuzumab is part of the monoclonal antibodies used as targeted therapy against HER2 receptor, whose major problem is its cardiac safety profile, where it has been associated with cardiotoxicity. The appearance of cardiotoxicity is an indication to stop therapy. Although the pathophysiological mechanism is poorly known, evidence indicates that oxidative stress plays a fundamental role causing DNA damage, increased cytosolic and mitochondrial ROS production, changes in mitochondrial membrane potential, intracellular calcium dysregulation, and the consequent cell death through different pathways. The aim of this review was to explore the use of antioxidants as adjuvant therapy to trastuzumab to prevent its cardiac toxicity, thus leading to ameliorate its safety profile in its administration.

Potential Antioxidant Multitherapy against Complications Occurring in Sepsis.

Septic shock currently represents one of the main causes of mortality in critical patient units with an increase in its incidence in recent years, and it is also associated with a high burden of morbidity in surviving patients. Within the pathogenesis of sepsis, oxidative stress plays an important role. The excessive formation of reactive oxygen species (ROS) leads to mitochondrial damage and vasomotor dysfunction that characterizes those patients who fall into septic shock. Currently, despite numerous studies carried out in patients with septic shock of different causes, effective therapies have not yet been developed to reduce the morbidity and mortality associated with this pathology. Despite the contribution of ROS in the pathophysiology of sepsis and septic shock, most studies performed in humans, with antioxidant monotherapies, have not resulted in promising data. Nevertheless, some interventions with compounds such as ascorbate, N-acetylcysteine, and selenium would have a positive effect in reducing the morbidity and mortality associated with this pathology. However, more studies are required to demonstrate the efficacy of these therapies. Taking into account the multifactorial features of the pathophysiology of sepsis, we put forward the hypothesis that a supplementation based on the association of more than one antioxidant compound should result in a synergistic or additive effect, thus improving the beneficial effects of each of them alone, potentially serving as a pharmacological adjunct resource to standard therapy to reduce sepsis complications. Therefore, in this review, it is proposed that the use of combined antioxidant therapies could lead to a better clinical outcome of patients with sepsis or septic shock, given the relevance of oxidative stress in the pathogenesis of this multi-organ dysfunction.

Humoral Immune Response of BNT162b2 and CoronaVac Vaccinations in Hemodialysis Patients: A Multicenter Prospective Cohort.

The CoronaVac vaccine is the most used anti-SARS-CoV-2 vaccine worldwide. Previous data indicate that this vaccine produces a lower immune response than RNA vaccines such as BNT162b2. End-stage renal disease (ESRD) patients have an increased rate of COVID-19 and a reduced immune response to vaccinations. Currently, there is little data on this population's immune response induced by CoronaVac. Methods: This study involved a prospective cohort of ESRD patients in chronic hemodialysis who received a two-dose immunization scheme of either CoronaVac (Sinovac Biotech) or BNT162b2 vaccines (Pfizer-BioNTech). We measured the plasma levels of anti-SARS-CoV-2 IgG antibodies. We determined antibody titers before immunization, 2 and 4 months after two doses, plus 4 months after a booster dose. Results: We evaluated 208 patients in three hemodialysis centers. The mean age was 62.6 ± 15.6 years, of whom 91 were female (41.75%). Eighty-one patients (38.94%) received the BNT162b2 vaccine and 127 (61.06%) received the CoronaVac vaccine. Patients who received the BNT162b2 vaccine had a higher humoral response compared to those who received the CoronaVac vaccine (4 months after the second dose: BNT162b2: 88.89%, CoronaVac: 51.97%, p < 0.001; 4 months after the booster: BNT162b2: 98.77%, CoronaVac: 86.61%, p < 0.001). Conclusions: Our results suggest that the CoronaVac vaccine induced a lower humoral response than the BNT162b2 vaccine in ESRD patients on hemodialysis.

Clinical Efficacy of SARS-CoV-2 Vaccination in Hemodialysis Patients.

Introduction: The COVID-19 pandemic is a global public health problem. Patients with end-stage renal disease on hemodialysis are at a higher risk of infection and mortality than the general population. Worldwide, a vaccination campaign has been developed that has been shown to reduce severe infections and deaths in the general population. However, there are currently limited data on the clinical efficacy of vaccinations in the hemodialysis population. Methods: A national multicenter observational cohort was performed in Chile to evaluate the clinical efficacy of anti-SARS-CoV-2 vaccination in end-stage renal disease patients on chronic hemodialysis from February 2021 to August 2021. In addition, the BNT162b2 (Pfizer-BioNTech) and CoronaVac (Sinovac) vaccines were evaluated. The efficacy of vaccination in preventing SARS-CoV-2 infection, hospitalizations, and deaths associated with COVID-19 was determined. Results: A total of 12,301 patients were evaluated; 10,615 (86.3%) received a complete vaccination (2 doses), 490 (4.0%) received incomplete vaccination, and 1196 (9.7%) were not vaccinated. During follow-up, 1362 (11.0%) patients developed COVID-19, and 150 died (case fatality rate: 11.0%). The efficacy of the complete vaccination in preventing infection was 18.1% (95% confidence interval [CI]:11.8-23.8%), and prevention of death was 66.0% (95% CI:60.6-70.7%). When comparing both vaccines, BNT162b2 and CoronaVac were effective in reducing infection and deaths associated with COVID-19. Nevertheless, the BNT162b2 vaccine had higher efficacy in preventing infection (42.6% vs. 15.0%) and deaths (90.4% vs. 64.8%) compared to CoronaVac. Conclusion: The results of our study suggest that vaccination against SARS-CoV-2 in patients on chronic hemodialysis was effective in preventing infection and death associated with COVID-19.

Pharmacological Effects of Caffeic Acid and Its Derivatives in Cancer: New Targeted Compounds for the Mitochondria.

Cancer is a complex pathology of great heterogeneity and difficulty that makes the constant search for new therapies necessary. A major advance on the subject has been made by focusing on the development of new drugs aimed to alter the metabolism of cancer cells, by generating a disruption of mitochondrial function. For this purpose, several new compounds with specific mitochondrial action have been tested, leading successfully to cell death. Recently, attention has centered on a group of natural compounds present in plants named polyphenols, among which is caffeic acid, a polyphenol that has proven to be a powerful antitumoral agent and a prominent compound for studies focused on the development of new therapies against cancer.In this review, we revised the antitumoral capacity and mechanisms of action of caffeic acid and its derivatives, with special emphasis in a new class of caffeic acid derivatives that target mitochondria by chemical binding to the lipophilic cation triphenylphosphonium.

Cardioprotective Mechanisms against Reperfusion Injury in Acute Myocardial Infarction: Targeting Angiotensin II Receptors.

Ischemia/reperfusion injury is a process associated with cardiologic interventions, such as percutaneous coronary angioplasty after an acute myocardial infarction. Blood flow restoration causes a quick burst of reactive oxygen species (ROS), which generates multiple organelle damage, leading to the activation of cell death pathways. Therefore, the intervention contributes to a greater necrotic zone, thus increasing the risk of cardiovascular complications. A major cardiovascular ROS source in this setting is the activation of multiple NADPH oxidases, which could result via the occupancy of type 1 angiotensin II receptors (AT1R); hence, the renin angiotensin system (RAS) is associated with the generation of ROS during reperfusion. In addition, ROS can promote the expression of NF-κΒ, a proinflammatory transcription factor. Recent studies have described an intracellular RAS pathway that is associated with increased intramitochondrial ROS through the action of isoform NOX4 of NADPH oxidase, thereby contributing to mitochondrial dysfunction. On the other hand, the angiotensin II/ angiotensin type 2 receptor (Ang II/AT2R) axis exerts its effects by counter-modulating the action of AT1R, by activating endothelial nitric oxide synthase (eNOS) and stimulating cardioprotective pathways such as akt. The aim of this review is to discuss the possible use of AT1R blockers to hamper both the Ang II/AT1R axis and the associated ROS burst. Moreover; we suggest that AT1R antagonist drugs should act synergistically with other cardioprotective agents, such as ascorbic acid, N-acetylcysteine and deferoxamine, leading to an enhanced reduction in the reperfusion injury. This therapy is currently being tested in our laboratory and has shown promising outcomes in experimental studies.

[Institutionalizing evidence-based policies in BrazilInstitucionalización de las políticas informadas por evidencia]. / Institucionalização das políticas informadas por evidências no Brasil.

OBJECTIVE: To evaluate capacities, organizational arrangements, and barriers to the implementation of Evidence Centers (NEvs) as part of Brazil's Evidence-Informed Policy Network (EVIPNet). METHOD: A mixed methods descriptive-analytical, multiple-case exploratory study was performed. Coordinators of active NEvs answered a questionnaire in three parts: participant characteristics, assessment of the capacity to "acquire, assess, adapt, and apply" evidence (4A), and open questions addressing organizational arrangements and barriers to the implementation of NEvs. RESULTS: The study included 15 NEvs, mostly from the Midwest; 73.3% were based in universities, while 20% were installed in state/city health departments or in the Ministry of Health. All coordinators had completed graduate training and 80% reported 1 to 5 years' experience with evidence-based policies as well as proficiency in English. None of the participants worked exclusively as NEv coordinator. NEv teams included health care professionals, students (undergraduate/graduate), professors, and civil servants from health departments. The data revealed high capacity to "acquire" and "assess" evidence, and low capacity to "adapt" and "apply" evidence. On average, three activities or products were developed yearly by each NEv, especially knowledge translation initiatives (systematic reviews and deliberative dialogues) and training for health care professionals, managers and undergraduate/graduate students. Five barrier categories were described: 1) financing, 2) network integration, 3) institutionalization of demands, 4) adaptive capacity, and 5) research communication skills to recommend actions at the local level. CONCLUSIONS: Trained human resources associated with academic and research institutions are available to support evidence-informed policies. However, the sustainability of NEvs depends on coordinated action to ensure the capacity to adapt and apply evidence.

OBJETIVO: Evaluar la capacidad, los arreglos organizativos y los obstáculos existentes para la aplicación de los núcleos de evidencia (NEv) de la Red de Políticas Informadas por Evidencia (EVIPNet) en Brasil. MÉTODOS: Se realizó un estudio descriptivo, analítico y exploratorio de casos múltiples, con un enfoque mixto. Los coordinadores de los NEv activos en el país respondieron a un instrumento dividido en tres partes: caracterización de la persona encuestada, evaluación de la capacidad de "adquirir, evaluar, adaptar y aplicar" evidencia (conocidas como 4A por su sigla en portugués) y temas de discusión abierta en los cuales se abordaron los arreglos organizativos y los obstáculos existentes para la aplicación de los NEv. RESULTADOS: Participaron en la investigación 5 NEv concentrados en la región Centro-Oeste; 73,3% tenían su sede en universidades y un 20% en secretarías estatales/municipales o en el Ministerio de Salud. Todos los coordinadores participantes tenían título de posgrado en sentido amplio o estricto y 80% afirmaron que tenían experiencia de 1 a 5 años en políticas informadas por evidencia (PIE) y que dominaban el inglés. Ningún coordinador trabajaba exclusivamente en el NEv. Los equipos incluían profesionales de salud, estudiantes (de grado/posgrado), profesores universitarios y empleados en comisión de servicio en las secretarías de salud. Se determinó que tenían gran capacidad para "adquirir" y "evaluar" y poca capacidad para "adaptar" y "aplicar" evidencias. En cuanto a actividades y productos, prevaleció la media de tres al año, con hincapié en los productos de traducción del conocimiento (la síntesis de la evidencia y los diálogos deliberantes) y la capacitación para profesionales de salud, gestores y alumnos de grado/posgrado. Se describieron cinco clases de obstáculos: 1) financiamiento, 2) integración de la red, 3) institucionalización de las demandas, 4) capacidad de adaptación y 5) habilidades de comunicación de las investigaciones para recomendar la adopción de medidas en el nivel local. CONCLUSIONES: Existen recursos humanos capacitados, vinculados a instituciones de investigación y enseñanza, para apoyar las PIE. Sin embargo, la sostenibilidad de los NEv depende de la adopción de medidas coordinadas para garantizar que existe la capacidad de adaptar y aplicar evidencia.

Avaliar capacidades, arranjos organizativos e barreiras à implementação dos Núcleos de Evidências (NEvs) da Rede de Políticas Informadas por Evidências (EVIPNet) no Brasil. Realizou-se um estudo exploratório de casos múltiplos, descritivo-analítico, com abordagem mista. Os coordenadores dos NEvs em atividade no país responderam um instrumento com três partes: caracterização do respondente, avaliação da capacidade de "adquirir, avaliar, adaptar e aplicar" evidências (4A) e questões abertas abordando arranjos organizativos e barreiras à implementação dos NEvs. Participaram da pesquisa 15 NEvs, concentrados no Centro-Oeste; 73,3% estavam sediados em universidades e 20% em secretarias estaduais/municipais ou no Ministério da Saúde. Dos coordenadores participantes, 100% possuíam pós-graduação lato e/ou strictu sensu e 80% referiram experiência de 1 a 5 anos em políticas informadas por evidências (PIE) e proficiência em inglês. Nenhum coordenador atuava exclusivamente no NEv. As equipes incluíam profissionais de saúde, estudantes (graduação/pós-graduação), docentes de universidades e servidores efetivos em secretarias de saúde. Foram identificadas alta capacidade para "adquirir" e "avaliar" e baixa capacidade para "adaptar" e "aplicar" evidências. Quanto a atividades e produtos, prevaleceu a média de três por ano, com destaque para produtos de tradução do conhecimento (sínteses de evidência e diálogos deliberativos) e capacitação para profissionais de saúde, gestores e alunos de graduação/pós-graduação. Cinco categorias de barreiras foram descritas: 1) financiamento, 2) integração da rede, 3) institucionalização das demandas, 4) capacidade de adaptação e 5) habilidades de comunicação de pesquisa para recomendar ações no nível local. Existem recursos humanos capacitados, vinculados a instituições de pesquisa e ensino, para apoiar as PIE. No entanto, a sustentabilidade dos NEvs depende de ações coordenadas para garantir a capacidade de adaptar e aplicar evidências.

Coordinators of active NEvs answered a questionnaire in three parts: participant characteristics, assessment of the capacity to "acquire, assess, adapt, and apply" evidence (4A), and open questions addressing organizational arrangements and barriers to the implementation of NEvs.The study included 15 NEvs, mostly from the Midwest; 73.3% were based in universities, while 20% were installed in state/city health departments or in the Ministry of Health. All coordinators had completed graduate training and 80% reported 1 to 5 years' experience with evidence-based policies as well as proficiency in English. None of the participants worked exclusively as NEv coordinator. NEv teams included health care professionals, students (undergraduate/graduate), professors, and civil servants from health departments. The data revealed high capacity to "acquire" and "assess" evidence, and low capacity to "adapt" and "apply" evidence. On average, three activities or products were developed yearly by each NEv, especially knowledge translation initiatives (systematic reviews and deliberative dialogues) and training for health care professionals, managers and undergraduate/graduate students. Five barrier categories were described: 1) financing, 2) network integration, 3) institutionalization of demands, 4) adaptive capacity, and 5) research communication skills to recommend actions at the local level. Trained human resources associated with academic and research institutions are available to support evidence-informed policies. However, the sustainability of NEvs depends on coordinated action to ensure the capacity to adapt and apply evidence.

[Comparative analysis of the glycemic response and glycemic index of instant mashed potatoes in subjects undergoing laparoscopic sleeve gastrectomy and control subjects]. / Análisis comparativo de la respuesta glicémica e índice glicérico del puré de papas instantáneo determinado en sujetos sometidos a gastrectomía vertical en manga laparoscópica y en sujetos controles.

BACKGROUND: The laparoscopic sleeve gastrectomy (LSG) is a successful surgical procedure for morbid obesity. However, post surgery weight regain is usual, thus applying the glycemic index could promote good weight control. OBJECTIVE: To compare the glycemic index (GI) and glycemic response (GR) obtained of instant mashed potatoes in individuals subjected to LSG versus control subjects. METHODS: GI and GR were assessed in 10 LSG subjects and compared with 10 controls. GI methodology proposed by FAO/WHO was used; instant mashed potatoes as test food and white bread as standard food (50g available CHO). Capillary blood sample 0 (fasting), 30, 60, 90 and 120 minutes. The GI was determined by trapezoidal method. ANOVA was used to compare a factor between RG and IG groups; t-student to compare RG between foods. Statistical significance p<0.05. RESULTS: The GR of instant mashed potatoes at 30 min was higher in the group operated (LSG 159,8 ± 25,9 versus control subjects 135,3 ± 17,3 mg/dl; p=0,023). In LSG group, the GR of instant mashed potatoes was higher than white bread at 30 min (159,8 ± 25,9 versus 136,3 ± 24,4 mg/dl respectively; p<0,01). The GI obtained from instant mashed potatoes was similar en both groups (LSG 119 versus control subjects 120; p=0,974). CONCLUSIONS: Instant mashed potatoes despite having similar GI in both groups, generates higher glycemic responses in LSG group, and its consumption possibly favoring weight regain.

Introducción: La gastrectomía vertical en manga laparoscópica (GVML) es una técnica quirúrgica exitosa para la obesidad mórbida. Sin embargo, es común la reganancia de peso post cirugía, pudiendo la utilización del índice glicémico favorecer un buen control de peso. Objetivo: Comparar la respuesta glicémica (RG) e IG del puré de papas instantáneo en sujetos sometidos a GVML versus sujetos controles. Métodos: Se evaluó RG e IG en 10 sujetos con GVML y 10 sujetos controles. Se utilizó la metodología del IG propuesta por FAO/OMS; como alimento de prueba, el puré de papas instantáneo; como alimento estándar, el pan blanco. Se obtuvo muestra de sangre capilar a los 0 (ayuno), 30, 60, 90 y 120 minutos. El IG se determinó por método trapezoidal. Se utilizó ANOVA de un factor para comparar RG e IG entre grupos; t-student para comparar RG entre alimentos. Significancia estadística p.
