Abstract Introduction: In Mexico, cardiac rehabilitation (CR) as an interdisciplinary intervention with therapeutic impact in patients with heart disease is growing. There is the need to know actual conditions of CR in our country. Objectives: The objective of this National Registry is to follow-up those existing and new CR units in Mexico through the comparison between the two previous registries, RENAPREC-2009 and RENAPREC II-2015 studies. This is a descriptive study focused on diverse CR activities such as assistance training, and certification of health professionals, barriers, reference, population attended, interdisciplinarity, permanence over time, growth prospects, regulations, post-pandemic condition, integrative characteristics, and scientific research. Results: Data were collected from 45 CR centers in the 32 states, 75.5% are private practice units, 67% are new, 33% were part of RENAPREC II-2015, and 17 have continued since 2009. With a better distribution of CR units along the territory, the median reference of candidates for CR programs is 9% with a significant reduction into tiempo of enrollment to Phase II admission (19 ± 11 days). Regarding to previous registries, the coverance of Phases I, II, and III is 71%, 100%, and 93%, respectively; and a coverance increases in evaluation, risk stratification, and prescription, more comprehensive attendance and prevention strategies. Conclusions: CR in Mexico has grown in the past 7 years. Even there is still low reference and heterogeneity in specific processes, there are strengths such as interdisciplinarity, scientific professionalization of specialists, national diversification, and an official society that are consolidated over time.

Abstract Some experimental results concerning the performance of fiber-reinforced soil composites made of soil and shredded fibers from waste tires are presented. The composite mixtures were prepared with fiber addition of 0, 15, 30, and 45 wt%. After molding, the specimens were oven-dried and tested for unconfined compressive strength and water immersion durability. The results showed an improvement in durability with the addition of fiber. The results also indicated good compressive strength performance for the composites with a fiber content of 15 and 30 wt%. The 30 wt% fiber addiction was the best choice because of the environmental sustainability appeal to solid waste reduction.

Resumen Objetivo: Evaluar las características tomográficas preoperatorias de la nariz y los senos paranasales de niños con dacriocistitis crónica. Método: Estudio prospectivo, observacional, transversal y descriptivo. Se evaluaron tomografías de senos paranasales de pacientes candidatos a dacriocistorrinostomía endoscópica, durante 2 años. Se identificaron características demográficas, hallazgos radiológicos, procesos inflamatorios y variantes anatómicas, utilizando la clasificación Lund-Mackay. Análisis estadístico con Stata 10.0, análisis descriptivo con t de Student: diferencia medias y χ2. Estudios logísticos para estimar la probabilidad entre variables. Resultados: Se incluyeron 27 hombres y 11 mujeres (n = 38). De ellos, 22 tenían afección del conducto nasolagrimal unilateral y 16 bilateral. Rango de puntuación de Lund-Mackay: 2-20. Once pacientes tuvieron patología asociada. Seno etmoidal anterior y maxilar más afectados (69%), complejo osteomeatal (68%), etmoidal posterior (51%). La probabilidad de que los pacientes con rinosinusitis grave puedan presentar dacriocistitis es 12 veces mayor que en los pacientes con < 12 puntos. Los hombres presentaron mayor gravedad, afectación y repercusión clínica. Conclusiones: Existe afección rinosinusal radiológica en la dacriocistitis, que debe ser evaluada y tratada en el preoperatorio para evitar complicaciones o reinfecciones posquirúrgicas.

Abstract Objective: To evaluate the preoperative tomographic characteristics of the nose and paranasal sinuses of children with chronic dacryocystitis. Method: Prospective, observational, cross-sectional, and descriptive study. CT scans of the paranasal sinuses of patients candidates for endoscopic dacryocystorhinostomy were evaluated for two years. Demographic characteristics, radiological findings, inflammatory processes and anatomical variants were identified using the Lund-Mackay classification. Statistic analysis. Stata 10.0, descriptive analysis, Student's t: mean difference and χ2. Logistic studies to estimate the probability between variables. Results: 27 men and 11 women (n = 38) were included. Of these, 22 had unilateral and 16 bilateral nasolacrimal duct involvement. Lund-Mackay score range: 2-20. Eleven patients had associated pathology. The most affected were anterior and maxillary ethmoidal sinus (69%), osteomeatal complex (68%), posterior ethmoidal (51%). Patients with severe rhinosinusitis are 12 times more likely to develop dacryocystitis than patients with < 12 points. Men presented greater severity, affectation, and clinical repercussion. Conclusions: There is radiological rhinosinusal involvement in dacryocystitis, which must be evaluated and treated preoperatively to avoid postoperative complications or reinfections.

Abstract Objective: To assess factors associated with emotional changes and Hyperactivity/Inattention (HI) motivated by COVID-19 quarantine in adolescents with immunocompromising diseases. Methods: A cross-sectional study included 343 adolescents with immunocompromising diseases and 108 healthy adolescents. Online questionnaires were answered including socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and validated surveys: Strengths and Difficulties Questionnaire (SDQ), Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0). Results: The frequencies of abnormal emotional SDQ scores from adolescents with chronic diseases were similar to those of healthy subjects (110/343 [32%] vs. 38/108 [35%], p = 0.548), as well as abnormal hyperactivity/inattention SDQ scores (79/343 [23%] vs. 29/108 [27%], p = 0.417). Logistic regression analysis of independent variables associated with abnormal emotional scores from adolescents with chronic diseases showed: female sex (Odds Ratio [OR = 3.76]; 95% Confidence Interval (95% CI) 2.00–7.05; p < 0.001), poor sleep quality (OR = 2.05; 95% CI 1.08–3.88; p = 0.028) and intrafamilial violence during pandemic (OR = 2.17; 95% CI 1.12–4.19; p = 0.021) as independently associated with abnormal emotional scores, whereas total PedsQL score was inversely associated with abnormal emotional scores (OR = 0.95; 95% CI 0.93–0.96; p < 0.0001). Logistic regression analysis associated with abnormal HI scores from patients evidenced that total PedsQL score (OR = 0.97; 95% CI 0.95–0.99; p = 0.010], changes in medical appointments during the pandemic (OR = 0.39; 95% CI 0.19–0.79; p = 0.021), and reliable COVID-19 information (OR = 0.35; 95% CI 0.16–0.77; p = 0.026) remained inversely associated with abnormal HI scores. Conclusion: The present study showed emotional and HI disturbances in adolescents with chronic immunosuppressive diseases during the COVID-19 pandemic. It reinforces the need to promptly implement a longitudinal program to protect the mental health of adolescents with and without chronic illnesses during future pandemics.

Abstract The litter deposited on the soil surface at various stages of decomposition is important for primary productivity that impacts the microbial communities and soil carbon storage. The objective of this study was to evaluate the accumulation and decomposition of cultural residues of Theobroma grandiflorum (Willd. ex. Spreng) Schum, Paullinia cupana (Mart.) Ducke, Bixa orellana L., and forest in the Amazon region. The study was carried out in the São Francisco settlement, Canutama in the south of Amazonas, in a randomized block experimental design, and the treatments consisted of four areas with different crops: 1 - P. cupana; 2 - T. grandiflorum; 3 - B. orellana; 4 - Native woodland area (forest), in time subdivided plots: 7, 15, 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, and 330 days after the distribution of the bags in the field, all with four repetitions. To evaluate the contribution and fractions of litter, conical collectors were used in each area, and collections were performed monthly in the period from March 2020 to February 2021. The estimate of the decomposition rate of the litter was done by quantifying the loss of mass, using litter bags, which allow for a direct analysis of the rate of decay over time. The forest and P. cupana environments presented the highest litter production, and greater deposition when compared to environments cultivated with T. grandiflorum and B. orellana. The forest and B. orellana areas showed the highest speed of decomposition, while the opposite situation occurred under T. grandiflorum and P. cupana cultivation.

Resumo A serrapilheira depositada na superfície do solo, em vários estágios de decomposição tem importância na produtividade primária que impacta nas comunidades microbianas e estocagem de carbono no solo. Objetivou-se neste trabalho avaliar o acúmulo e decomposição dos resíduos culturais de cupuaçu, guaraná, urucum e floresta na região do Amazonas. O estudo foi realizado no assentamento São Francisco, Canutama no Sul do Amazonas, em delineamento experimental de blocos casualisados, sendo que os tratamentos constaram de quatro áreas com diferentes culturas: 1- Guaraná; 2 – Cupuaçu; 3 – Urucum; 4 – Área de mata nativa (floresta), em parcelas subdivididas no tempo: 07, 15, 30, 60, 90, 120, 150, 180, 210, 240, 270 e 300, 330 dias após a distribuição das sacolas no campo, todas com 04 repetições. Para avaliar o aporte e frações dá serapilheira, foram utilizados coletores cônicos em cada área, sendo as coletas realizadas mensalmente no período de março de 2020 a fevereiro de 2021. A estimativa da taxa de decomposição da serrapilheira foi realizada pela quantificação da perda de massa, utilizando-se litter bags, os quais permitem analisar de forma direta a taxa de decaimento ao longo do tempo. Os ambientes de floresta e guaraná apresentaram as maiores produções de serapilheira, e maior deposição quando comparados aos ambientes cultivados com cupuaçu e urucum. As áreas de floresta e urucum apresentaram a maior velocidade de decomposição, já a situação inversa ocorreu sob o cultivo do cupuaçu e guaraná.

Abstract The objective of this study was to evaluate reproductive traits in adults of Astyanax lacustris subjected to different spawning inducers. The study involved 240 females (12.54 g ± 2.33 and 7.66 cm ± 0.63 cm) and 240 males (5.83 g ± 0.39 g and 6.14 cm ± 0.64 cm), all at reproductive age. Three different inducers were evaluated: (i) 0.4 pellets of Ovopel®/kg of body weight; (ii) 0.5 ml of buserelin acetate/kg of body weight; and (iii) carp pituitary extract (CPE) (5.5 mg CPE/kg body weight for females and 2.5 mg CPE/kg body weight for males), as well as saline solution (without hormone). The degree-hours for spawning were greater (P<0.05) for the Ovopel® treatment (with 204.93) than in the treatment with CPE (183.2). Ovary weight and gonadosomatic index were higher (P<0.05) in CPE and Ovopel® treatments when compared to buserelin acetate. The number of oocytes per female, absolute and relative fecundity were greater (P<0.05) for Ovopel® and CPE treatments. Fertilization rate was higher (P<0.05) in treatment with buserelin acetate (82.3%) in relation to Ovopel® (72.33%) and CPE (62.40%) treatments, and the highest (P<0.05) hatching rates were achieved with buserelin acetate and Ovopel®. The number of larvae per female body weight was greater (P<0.05) when Ovopel® was used. In conclusion, Ovopel® proves to be a more effective reproductive inducer for induced reproduction of A. lacustris when compared to CPE and buserelin acetate.

Resumo O objetivo deste estudo foi avaliar as características reprodutivas em adultos de Astyanax lacustris submetidos a diferentes indutores da desova. Foram utilizadas 240 fêmeas (12,54 g ± 2,33 e 7,66 cm ± 0,63 cm) e 240 machos (5,83 g ± 0,39 g e 6,14 cm ± 0,64 cm), todos em idade reprodutiva. Três diferentes indutores foram avaliados: (i) 0,4 pellets de Ovopel®/kg de peso corporal; (ii) 0,5 ml de acetato de buserelina/kg de peso corporal; e (iii) Extrato de Pituitária de Carpa (CPE) (5,5 mg CPE/kg de peso corporal para fêmeas e 2,5 mg de CPE/kg de peso corporal para machos) e solução salina (sem hormônio). Horas-grau para desova foi maior (P<0,05) no tratamento com Ovopel® (204,93) do que no tratamento com CPE (183,2). O peso das gônadas e o índice gonadossomático foram maiores (P<0,05) nos tratamentos com CPE e Ovopel® quando comparados ao acetato de buserelina. O número de oócitos por fêmea, a fecundidade absoluta e relativa foram maiores (P<0,05) para os tratamentos com Ovopel® e CPE. A taxa de fertilização foi maior (P<0,05) no tratamento com acetato de buserelina (82,3%) em relação aos tratamentos com Ovopel® (72,33%) e CPE (62,40%); e maior (P<0,05) taxa de eclosão foi obtida nos tratamentos com acetato de buserelina e Ovopel®. O número de larvas por peso corporal da fêmea foi maior (P<0,05) quando utilizado Ovopel®. Conclui-se que Ovopel® é um indutor reprodutivo mais eficaz para a reprodução induzida de A. lacustris quando comparado ao CPE e ao acetato de buserelina.

Abstract: En | Text: En | PDF: En

Objective: To compare plasma concentrations of cannabidiol (CBD) following oral administration of two formulations of the drug (powder and dissolved in oil), and to evaluate the effects of these distinct formulations on responses to emotional stimuli in healthy human volunteers. Methods: In a randomized, double-blind, placebo-controlled, parallel-group design, 45 healthy male volunteers were randomly assigned to three groups of 15 subjects that received either 150 mg of CBD powder; 150 mg of CBD dissolved in corn oil; or placebo. Blood samples were collected at different times after administration, and a facial emotion recognition task was completed after 150 min. Results: There were no significant differences across groups in the subjective and physiological measures, nor in the facial emotion recognition task. However, groups that received the drug showed statistically significant differences in baseline measures of plasma CBD, with a significantly greater difference in favor of the oil formulation. Conclusion: When administered as a single 150-mg dose, neither formulation of oral CBD altered responses to emotional stimuli in healthy subjects. The oil-based CBD formulation resulted in more rapid achievement of peak plasma level, with an approximate fourfold increase in oral bioavailability.

Abstract Classic phase retrieval techniques use intensity patterns to obtain typical aberrations such as coma or astigmatism. However, the patterns obtained using the transport of intensity equation techniques have not been studied yet. In this work, we propose a method to obtain intensity distributions of some aberration wavefronts. We expect that this characterization method may facilitate new testing strategies in optical workshops.

Analisamos 226 estômagos de K. heteresthes e 425 de M. lepidura, sendo utilizados os métodos volumétrico e frequência de ocorrência, aplicando-se o índice de importância alimentar. Para a similaridade das dietas entre as espécies calculamos a sobreposição de nicho com índice de Pianka. Ambas as espécies no rio Juruena têm preferência alimentar por artrópodes (IAi > 0,95), no rio Teles Pires a dieta concentra-se em três fontes para ambas espécies: artrópodes (IAi > 0,52), vegetais (IAi > 0,33) e peixes (IAi > 0,12). A dieta é dissimilar quando comparados os ambientes (ANOSIM, R ≥ 0,57; p < 0,001), com alta sobreposição de nicho trófico (α > 0,97), independente do ambiente amostrado. No rio Teles Pires, ambas as espécies foram classificadas como onívoras com tendência insetívora e no rio Juruena ocorre o comportamento insetívoro.

Abstract The composition of the diet of two species of characids (Knodus heteresthes and Moenkhausia lepidura) was evaluated in the Teles Pires and Juruena Rivers, sampled in September and October 2016. We analyzed 226 stomachs of K. heteresthes and 425 of M. lepidura. The analysis of the stomach contents was based on volumetric and frequency of occurrence methods, applying the food importance index. For the similarity of the diets between the species we calculated the niche overlap with Pianka’s index. Both species in the Juruena River have a dietary preference for arthropods (IAi > 0.95). In the Teles Pires River the diet is concentrated in three sources for both species: arthropods (IAi > 0.52), vegetables (IAi > 0.33) and fish (IAi > 0.12). The diet was dissimilar when compared to environments (ANOSIM, R ≥ 0.57, p < 0.001) with high trophic niche overlap (α > 0.97), regardless of the sampled environment. In the Teles Pires River, both species were classified as omnivorous with an insectivorous tendency and in the Juruena River the insectivorous behaviour occurs.

OBJECTIVE: To assess the possible factors that influence sleep quality in adolescents with and without chronic immunosuppressive conditions quarantined during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: This cross-sectional study included 305 adolescents with chronic immunocompromised conditions and 82 healthy adolescents. Online surveys were completed, which included questions on socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and the following validated questionnaires: the Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0), and Pediatric Outcome Data Collection Instrument (PODCI). RESULTS: The median current age [14 (10-18) vs. 15 (10-18) years, p=0.847] and frequency of female sex (62% vs. 58%, p=0.571) were similar in adolescents with chronic conditions compared with healthy adolescents. The frequency of poor sleep quality was similar in both groups (38% vs. 48%, p=0.118). Logistic regression analysis, including both healthy adolescents and adolescents with chronic conditions (n=387), demonstrated that self-reported increase in screen time (odds ratio [OR] 3.0; 95% confidence interval [CI] 1.3-6.8; p=0.008) and intrafamilial violence report (OR 2.1; 95% CI 1.2-3.5; p=0.008) were independently associated with poor sleep quality in these adolescents. However, the PODCI global function score was associated with a lower OR for poor sleep quality (OR 0.97; 95% CI 0.94-0.99; p=0.001). Further logistic regression, including only adolescents with chronic conditions (n=305), demonstrated that self-reported increase in screen time (OR 3.1; 95% CI 1.4-6.8; p=0.006) and intrafamilial violence report (OR 2.0; 95% CI 1.2-3.4; p=0.011) remained independently associated with poor quality of sleep, whereas a lower PODCI global function score was associated with a lower OR for sleep quality (OR 0.96; 95% CI 0.94-0.98; p<0.001). CONCLUSION: Self-reported increases in screen time and intrafamilial violence report impacted sleep quality in both healthy adolescents and those with chronic conditions. Decreased health-related quality of life was observed in adolescents with poor sleep quality.

OBJECTIVES: To prospectively evaluate demographic, anthropometric and health-related quality of life (HRQoL) in pediatric patients with laboratory-confirmed coronavirus disease 2019 (COVID-19) METHODS: This was a longitudinal observational study of surviving pediatric post-COVID-19 patients (n=53) and pediatric subjects without laboratory-confirmed COVID-19 included as controls (n=52) was performed. RESULTS: The median duration between COVID-19 diagnosis (n=53) and follow-up was 4.4 months (0.8-10.7). Twenty-three of 53 (43%) patients reported at least one persistent symptom at the longitudinal follow-up visit and 12/53 (23%) had long COVID-19, with at least one symptom lasting for >12 weeks. The most frequently reported symptoms at the longitudinal follow-up visit were headache (19%), severe recurrent headache (9%), tiredness (9%), dyspnea (8%), and concentration difficulty (4%). At the longitudinal follow-up visit, the frequencies of anemia (11% versus 0%, p=0.030), lymphopenia (42% versus 18%, p=0.020), C-reactive protein level of >30 mg/L (35% versus 0%, p=0.0001), and D-dimer level of >1000 ng/mL (43% versus 6%, p=0.0004) significantly reduced compared with baseline values. Chest X-ray abnormalities (11% versus 2%, p=0.178) and cardiac alterations on echocardiogram (33% versus 22%, p=0.462) were similar at both visits. Comparison of characteristic data between patients with COVID-19 at the longitudinal follow-up visit and controls showed similar age (p=0.962), proportion of male sex (p=0.907), ethnicity (p=0.566), family minimum monthly wage (p=0.664), body mass index (p=0.601), and pediatric pre-existing chronic conditions (p=1.000). The Pediatric Quality of Live Inventory 4.0 scores, median physical score (69 [0-100] versus 81 [34-100], p=0.012), and school score (60 [15-100] versus 70 [15-95], p=0.028) were significantly lower in pediatric patients with COVID-19 at the longitudinal follow-up visit than in controls. CONCLUSIONS: Pediatric patients with COVID-19 showed a longitudinal impact on HRQoL parameters, particularly in physical/school domains, reinforcing the need for a prospective multidisciplinary approach for these patients. These data highlight the importance of closer monitoring of children and adolescents by the clinical team after COVID-19.

Resumen Se desarrolló un inhibidor a base de linaza (Linum usitatissimum) que controlara la precipitación de incrustaciones a nivel experimental. Para ello inicialmente se extrajo el gel de linaza mediante un proceso de hidrólisis y a partir de éste se formularon los distintos inhibidores con concentraciones de 30, 40 y 50% m/V, estudiándose así las características fisicoquímicas de cada producto y del gel de linaza. Se formuló un agua sintética y se recolectó una muestra de agua de producción proveniente del campo Oritupano, las cuales fueron caracterizadas mediante pruebas fisicoquímicas. Posteriormente se evaluó la eficiencia de inhibición del producto formulado, considerando la norma NACE TM 0374-2007, a las dosis de 10, 55 y 100 ppm, resultando ser el inhibidor de 50% m/V el más eficiente, arrojando valores de eficiencia comprendidos entre 59% y 95.67% para el agua de producción y de 36.67% y 92.22% para el agua sintética, dando a demostrar que a mayor concentración aumentaba la eficiencia. Para finalizar, se aplicó un análisis de varianza ANOVA entre los inhibidores formulados y un inhibidor comercial de referencia, obteniendo un comportamiento bastante similar al inhibidor patrón y demostrando su eficiencia. Concluyendo que los inhibidores a base de gel de linaza resultaron ser eficientes en la inhibición de incrustaciones minerales y la precipitación de sales, debido a que, en algunos casos, presentaron eficiencias mayores que el producto comercial evaluado.

Abstract A linseed-based inhibitor (Linum usitatissimum) was developed that would control the scale precipitation applying experimental trials. The linseed gel was initially extracted by a hydrolysis process and then different inhibitors were formulated at 30, 40 and 50 %m/V concentrations. In order to study the physicochemical characteristics of each product and the linseed gel. A synthetic water was formulated and a sample of production water from the Oritupano oilfield was collected, they were characterized by physicochemical tests. Subsequently, the inhibition efficiency of the formulated product was evaluated, considering NACE TM 0374-2007, at different doses (10, 55 and 100 ppm). The 50 %m/V inhibitor was the most efficient, obtaining efficiency values between 59% and 95.67% for the production water and 36.67% and 92.22% for the synthetic water, showing that at higher concentration, the efficiency increases. Finally, an analysis of variance (ANOVA) was applied between the formulated inhibitors and a commercial reference inhibitor, obtaining a behavior quite similar to the standard inhibitor and demonstrating its efficiency. Concluding that linseed gel-based inhibitors were efficient in mineral scales and salt precipitation inhibition, because in some cases they showed greater efficiencies than the commercial product evaluated.

Abstract: En | Text: En | PDF: En

Current pharmacotherapy of Parkinson’s disease (PD) is palliative and unable to modify the progression of neurodegeneration. Treatments that can improve patients’ quality of life with fewer side effects are needed, but not yet available. Cannabidiol (CBD), the major non-psychotomimetic constituent of cannabis, has received considerable research attention in the last decade. In this context, we aimed to critically review the literature on potential therapeutic effects of CBD in PD and discuss clinical and preclinical evidence supporting the putative neuroprotective mechanisms of CBD. We searched MEDLINE (via PubMed) for indexed articles published in English from inception to 2019. The following keywords were used: cannabis; cannabidiol and neuroprotection; endocannabinoids and basal ganglia; Parkinson’s animal models; Parkinson’s history; Parkinson’s and cannabidiol. Few studies addressed the biological bases for the purported effects of CBD on PD. Six preclinical studies showed neuroprotective effects, while three targeted the antidyskinetic effects of CBD. Three human studies have tested CBD in patients with PD: an open-label study, a case series, and a randomized controlled trial. These studies reported therapeutic effects of CBD on non-motor symptoms. Additional research is needed to elucidate the potential effectiveness of CBD in PD and the underlying mechanisms involved.
