RESUMO

Bakery products, especially bread, exist in many homes worldwide. One of the main reasons for its high consumption is that the main raw material is wheat, a cereal that can adapt to a wide variety of soils and climates. However, the nutritional quality of this raw material decreases during its industrial processing, decreasing the value of fibers, proteins, and minerals. Therefore, bread has become a product of high interest to increase its nutritional value. Due to the high consumption of bread, this paper provides a general description of the physicochemical and rheological changes of the dough, as well as the sensory properties of bread by incorporating alternative flours such as beans, lentils, and soy (among others). The reviewed data show that alternative flours can improve fiber, macro, and micronutrient content. The high fiber content reduces the quality of the texture of the products. However, new processing steps or cooking protocols, namely flour proportions, temperature, cooking, and fermentation time, can allow adjusting production variables and optimization to potentially overcome the decrease in sensory quality and preserve consumer acceptance.

RESUMO

The component Allee effect (AE) is the positive correlation between an organism's fitness component and population density. Depending on the population spatial structure, which determines the interactions between organisms, a component AE might lead to positive density dependence in the population per-capita growth rate and establish a demographic AE. However, existing spatial models impose a fixed population spatial structure, which limits the understanding of how a component AE and spatial dynamics jointly determine the existence of demographic AEs. We introduce a spatially explicit theoretical framework where spatial structure and population dynamics are emergent properties of the individual-level demographic and movement rates. This framework predicts various spatial patterns depending on its specific parametrization, including evenly spaced aggregates of organisms, which determine the demographic-level by-products of the component AE. We find that aggregation increases population abundance and allows population survival in harsher environments and at lower global population densities when compared with uniformly distributed organisms. Moreover, aggregation can prevent the component AE from manifesting at the population level or restrict it to the level of each independent aggregate. These results provide a mechanistic understanding of how component AEs might operate for different spatial structures and manifest at larger scales.

RESUMO

The development of B cells into antibody-secreting plasma cells is central to the adaptive immune system as they induce protective and specific antibody responses against invading pathogens. Various studies have shown that, during this process, hormones can play important roles in the lymphopoiesis, activation, proliferation, and differentiation of B cells, and depending on the signal given by the receptor of each hormone, they can have a positive or negative effect. In autoimmune diseases, hormonal deregulation has been reported to be related to the survival, activation and/or differentiation of autoreactive clones of B cells, thus promoting the development of autoimmunity. Clinical manifestations of autoimmune diseases have been associated with estrogens, prolactin (PRL), and growth hormone (GH) levels. However, androgens, such as testosterone and progesterone (P4), could have a protective effect. The objective of this review is to highlight the links between different hormones and the immune response mediated by B cells in the etiopathogenesis of systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and multiple sclerosis (MS). The data collected provide insights into the role of hormones in the cellular, molecular and/or epigenetic mechanisms that modulate the B-cell response in health and disease.

RESUMO

SUMMARY: The aim was to analyze the relationship between somatic maturation and physical performance in male youth soccer players belonging to a professional Mexican academy. In 121 male soccer aged 11 to 16 years from a professional academy the peak height velocity (PHV), percentage of adult height (PAS), jump capacity, sprint, intermittent speed and muscle mass were estimated. ANOVA was conducted to compare performance variables among maturity somatic categories and percentiles were calculated based on maturity offset using LMS method. Furthermore, a general linear model was employed to determine the explanatory variables for performance. Post-PHV soccer players demonstrated superior physical performance across several tests compared to Pre-PHV (p<0.001) and Circa-PHV (p<0.001) players. The smoothed percentile values of performance tests, based on somatic maturation, indicated progressive performance enhancement as individuals approached PHV (-2 to 2 years from PHV) (p<0.005). PHV was associated with jump capacity (p<0.001) and intermittent speed (p=0.007) while PAS was associated with time in sprint (p=.0004). In conclusion PHV and PAS explained better performance than chronological age, body composition characteristics, injuries, or training factors.

RESUMO

True brachial artery aneurysms are rare. We present the case of a 47-year-old male who was referred to our clinic for the evaluation of progressive right arm claudication. He had suffered a gunshot wound in the right elbow 16 years before his symptoms. Computed tomography angiography revealed a thrombosed true brachial artery aneurysm. The patient was placed in the operating room, and aneurysm resection and reconstruction were performed using an interposition saphenous vein graft. His postoperative period was uneventful, and 1 year after the procedure, he remained asymptomatic. True brachial artery aneurysms associated with remote traumas are rare. This case illustrates the clinical presentation and successful management of arterial reconstruction using an autologous vein graft.

RESUMO

INTRODUCTION: The management of ureteral strictures longer than 1-2 cm must be treated by major surgery (1, 2). The strictures located at the distal part of the ureter can be managed by a ureteral reimplantation using a psoas hitch or a Boari flap depending on its proximity to the bladder (3). Those located at the proximal ureter can be treated by a pyeloplasty (4). The ureteric strictures in the mid-ureter are the ones that pose a greater challenge for the urologist because a ureteral substitution is needed, either using a segment of the intestine or a buccal mucosa graft (5, 6). Our main objective is to present the management and results at 36 months of a patient with a right mid-ureter stricture. MATERIAL AND METHODS: A 63-year-old male with chronic kidney disease (CKD) and a right single functioning kidney was referred to our department with the diagnosis of a 3 cm stricture in the right mid-ureter. He had a long-term JJ-stent in place but in the last year we had to replace it three times precociously and he even needed the placement of a nephrostomy tube due to the obstruction of the JJ-stent. Accordingly, a permanent resolution was sought and a laparoscopic onlay-flap ureteroplasty using cecal appendix was performed. RESULTS: The first step was to identify the cecal appendix. Then we identified and dissected the ureter. With the ureter dissected, we performed a ureteroscopy to pinpoint the stricture. Once we knew where the stricture was, we proceeded with the ureterotomy and preparation of the cecal appendix. The final step was to perform the ureteroplasty between the ureter and the cecal appendix placing a JJ-stent before the last stitches were done. Total operative time was 190 minutes without any intraoperative complication. The JJ-stent was removed 7 weeks later. The follow-up of the patient was done with regular blood test and ultrasound to rule out deterioration of the CKD and worsening of the residual hydronephrosis. With a follow-up of 36 months, the patient is stent free, he hasn't had any further intervention and neither the CKD nor the hydronephrosis haven't worsened. CONCLUSIONS: Laparoscopic onlay-flap ureteroplasty using cecal appendix is a feasible and well tolerated procedure for patients with right mid-ureter stricture. However, we must bear in mind the difficulty of these cases and they should be performed in expert centers.

RESUMO

BACKGROUND: Caring for people with dementia (PwD) usually triggers stress and leads to mental and somatic health complaints (SHCs). Physical activity (PA) can provide burden relief in PwD caregivers, but it is not clear whether PA habits would contribute to reducing SHCs. This study aims to analyze the effect of PA on the relationship between burden and SHCs in a sample of family caregivers of PwD. METHODS: One hundred and fifty-seven caregivers of PwD reported their PA habits, and completed the Giessen's Subjective Health Complaints Questionnaire (GBB-8) and the Zarit Burden Interview (ZBI). The relationship between PA habits, burden of care (ZBI), and SHCs (B-GBB-8 scale) was examined. Subsequently, the moderating effect of PA habits on the relationship between burden and SHCs was tested. RESULTS: PA habit was inversely associated with ZBI (rbp = -0.242) and GBB-8 scores (rbp (Gastrointestinal) = -0.174; rbp (Musculoskeletal) = -0.195; rbp (Exhaustion) = -0.247; rbp (Cardiovascular) = -0.250; and rbp (Overall) = -0.257, respectively), whereas moderate positive correlations were found between ZBI and GBB-8 scores (r (Gastrointestinal) = 0.483; r (Musculoskeletal) = 0.536; r (Exhaustion) = 0.542; r (Cardiovascular) = 0.438; and r (Overall) = 0.598, respectively). The interaction effect of PA habit and burden was significant for the overall SHCs (b = -0.11; P < 0.05) and cardiovascular complaints (b = -0.06; P < 0.05). However, the association between burden and SHCs was significant (P < 0.001) only for sedentary caregivers. CONCLUSION: These findings indicate that maintaining an active lifestyle through regular PA could potentially help alleviate the adverse effects of caregiver burden on somatic health among caregivers of PwD. Encouraging and endorsing PA interventions for informal caregivers might yield substantial advantages for their health and general well-being.

RESUMO

Introducción: Se presenta el caso clínico de un varón de 15 años con fracturas de huesos cortos del pie derecho como consecuencia de un accidente de tránsito. Tras 24 h de evolución, ingresa con disnea, desaturación, pico febril objetivo y posterior desarrollo de insuficiencia respiratoria. Ante la sospecha clínica de síndrome de embolia grasa, se solicita una angiotomografía pulmonar que confirma el diagnóstico. Se trata de una entidad inusual en pacientes con este tipo de fractura. El tratamiento inicial consistió en vigilancia estrecha en la unidad de cuidados intensivos, medidas de soporte con oxígeno suplementario, terapia res-piratoria y manejo quirúrgico de las fracturas. La evolución clínica del paciente fue adecuada y el cuadro respiratorio se resolvió por completo. Conclusiones: El síndrome de embolia grasa secundario a fracturas de huesos cortos es un cuadro infrecuente; por lo tanto, es preciso tener un alto grado de sospecha diagnóstica, no solo en los escenarios más comunes, sino también en este tipo de contextos inusuales y retadores, que permita su identificación temprana y, de esta forma, implementar un manejo oportuno y generar un impacto favorable en los desenlaces clínicos y en la disminución del riesgo de secuelas a largo plazo. Nivel de Evidencia: IV

Introduction: We present the clinical case of a 15-year-old male who sustained fractures to the short bones of his right foot as a result of a traffic accident. After 24 hours of evolution, he was admitted for dyspnea, desaturation, an objective febrile peak, and the development of respiratory failure. Given the clinical suspicion of fat embolism syndrome, pulmonary angiotomography was requested, which confirmed the diagnosis. This is a rare finding in patients with this type of fracture. The initial treatment included close monitoring in the intensive care unit, supportive measures such as supplemental oxygen, respiratory therapy, and surgical fracture management. The patient's clinical progression was adequate, and the respiratory condition resolved completely. Conclusion: Fat embolism syndrome resulting from short bone fractures is a rare condition; therefore, it is necessary to have a high level of diagnostic suspicion, not only in the most common scenarios, but also in these unusual and challenging contexts, which allows for its early detection and, as a result, timely management, which has a positive impact on clinical outcomes and reduces the risk of long-term sequelae. Level of Evidence: IV

RESUMO

Ethnobotanical studies that use the participatory research approach seek to involve the residents of a community in different stages of the study, promoting the registration, dissemination and strengthening of local knowledge, as well as the empowerment of decisions related to the sustainable use and management of resources. Using the participatory methodology, this study recorded and made a comparative analysis on the use of plants in two quilombola communities (Quilombo do Cambury-QC and Quilombo da Fazenda-QF) in the State of São Paulo. After a training on anthropological and botanical methods, local researchers selected and interviewed the local experts, recording their knowledge on plant uses and collecting the indicated plants, to be identified and deposited in herbariums. In addition, participant observation and field diaries were used by the academic researchers, helping to analyze the data. To test the differences in the composition of species known to local community, a Jaccard dissimilarity matrix was created, and a Permanova test was employed. During the 178 days of fieldwork, three local researchers from the QC and two from the QF, selected nine and eight experts on the uses of the plants in each quilombo, respectively, corresponding to 214 plant species, indicated for eight ethnobotanical categories. Our hypothesis has been confirmed, since the traditional knowledge found in both quilombos, regarding plant uses and the number of plant species by category, are distinct, since each community occupies particular plant areas and different phytophysiognomies. Most of the indicated species are native to the Atlantic forest, and no significant differences were observed in the proportion of native species vs. introduced among quilombos for any of the categories of use studied. Furthermore, the innovative methodology used, participatory ethnobotany, contributed to the empowerment of community members with regard to the use of their available resources in the environment in which they live, while retaining the intellectual property rights over their own knowledge.

RESUMO

BACKGROUND: Previous research suggests that the mental health impacts of the COVID-19 pandemic were stronger during the first months of it. It has also been proposed that those impacts depended on gender and other social determinants. AIMS: We aim to describe the change in prevalence of mental health problems (symptoms of common mental disorders [CMD], alcohol, and drug use) between two time periods during the pandemic, and the association of mental health problems with social determinants, in adolescents and young adults in Mexico. METHODS: We conducted a repeated cross-section analysis of data from VoCes-19, an online survey in November 2020 to February 2021 and November 2021 to March 2022 (combined n = ×224,099). We assessed the change in the prevalence of mental health problems, the differences in prevalence and change in the prevalence by gender, and the association of social determinants and pandemic-related variables with mental health problems, by means of multivariate regression models. RESULTS: The prevalence of CMD decreased (46.0% vs. 42.4%), while the prevalence of alcohol (frequent use 8.4% vs. 10.3%) and drug use (4.6% vs. 7.7%) increased. The three conditions increased more among girls/young women and trans/queer/non-binary participants than among boys/young men. CONCLUSIONS: The results point to the importance of considering the gendered social context of young people. A better understanding of the social circumstances that relate with mental health is required to inform interventions for these age groups.

RESUMO

Polyphenols called procyanidins can be extracted from agro-industrial waste like litchi peel and coffee pulp. However, their efficacy is limited due to instability, which hinders both the bioavailability and preservation of their activity. This study aims to establish the ideal encapsulation conditions required to preserve the procyanidin properties found in extracts taken from litchi peel and coffee pulp. To attain the maximum procyanidin encapsulation efficacy (EE), the Taguchi method was utilized to streamline the spray-drying conditions for different wall materials-maltodextrin (MD), whey protein (WP), citrus pectin (CP), and skim milk (SM). The optimized conditions consisted of feed flow (3, 4.5, and 6 mL/min), temperature (125, 150, and 175 °C), and airflow (30, 35, and 40 m3/h). The microcapsules were characterized using ABTS, DPPH, lipoperoxidation, and scanning electron microscopy. Objective evaluations revealed that MD was the most effective encapsulation material for the litchi extract, whereas WP was the optimal option for the coffee extract. Of all the factors considered in the spray-drying process, feed flow had the strongest impact. The spray-drying process for the litchi peel extracts achieved high procyanidin encapsulation efficiencies at a feed flow rate of 4.5 mL/min, a temperature of 150 °C, and an airflow rate of 35 m3/h. Meanwhile, the coffee extract spray drying achieved similar results at a feed flow rate of 4.5 mL/min, a temperature of 175 °C, and an airflow rate of 40 m3/h. Encapsulation efficiencies of 98.1% and 93.6% were observed for the litchi and coffee extracts, respectively, under the mentioned optimal conditions. The microencapsulation process was successful in preserving the antioxidant properties of procyanidins. The microcapsules' size ranged from 2.6 to 3.2 micrometers. The results imply that the phenolic compounds present in the extracts function as effective antioxidant agents.

RESUMO

This descriptive prospective study investigated the clinical features and treatment adherence of individuals who started the treatment for Pulmonary tuberculosis (TB) during the COVID-19 pandemic in São Luís. Thirty-six TB patients and thirty-five age/sex-matched individuals were recruited between January 2021 and January 2022. The clinical features, sociodemographic information, and serum were obtained at the diagnosis time. Adherence to treatment and adverse reactions were investigated monthly. The most common symptoms in TB patients were cough (91.6%) and fever (83.3%). All TB patients had elevated pre-therapy levels of CRP and reduced HDL: 88.9% presented hypocalcemia and 47.2% showed elevated ALP and GGT. TB patients showed higher levels of ALT, AST, ALP, GGT, CRP, amylase, and triglycerides than the comparison group (p < 0.05), while the calcium levels were reduced (p < 0.0001). TB patients with anti-SARS-CoV-2-IgG antibodies (seroprevalence of 66.7%) presented higher values of amylase and lower CRP levels (p < 0.05). Most patients (~70%) reported at least one adverse drug reaction, mainly pruritus and nausea. The treatment abandonment rate was 19.2%. In conclusion, TB patients showed elevated pre-therapy levels of CRP, low levels of HDL, and hypocalcemia. Liver and pancreatic functions were also compromised in several patients before the therapy. The treatment non-adherence rate observed was similar to other studies performed before the pandemic period.

RESUMO

Abstract Introduction Resilience is the capacity in which the qualities and resources of the individual help in the successful coping of adverse situations. Studying the construct of resilience requires seeing it as a process and not only a characteristic of the individual. Saavedra's resilient response is a model that fits this idea and explains resilience satisfactorily. Having a measuring instrument for health personnel working in hospitals would allow discovering its benefits as a protective factor in the workplace. Objective Adapt and validate the Resilience Scale SV-RES in hospital health professionals in Mexico. Method Based on recent research literature, including response models and modified and adapted items from the Resilience Scale SV-RES, a total of 909 health professionals responded. Distribution, factor analysis, and internal consistency tests were performed. Results The process led to a scale of 28 items grouped into six factors with an overall internal consistency of (α = .908) and 50.5% of explained variance. Discussion and conclusion The Resilience Scale SV-RES has adequate psychometric properties that make it appropriate to measure the resilience capacity of hospital health professionals in Mexico.

Resumen Introducción La resiliencia es la capacidad en que las cualidades y recursos del individuo le ayudan al afrontamiento exitoso de situaciones adversas. Se ha advertido que estudiar el concepto de resiliencia requiere verse como un proceso y no sólo como elementos característicos del individuo, un modelo que explica de manera adecuada este proceso es el modelo de respuesta resiliente de Saavedra. Contar con un instrumento que permita su medición en personal de salud hospitalario permitiría descubrir su beneficio como factor protector en el lugar de trabajo y diseñar intervenciones preventivas o remediales. Objetivo Adaptar y validar la Escala de Resiliencia SV-RES en profesionales de salud hospitalaria en México. Método Se tomó como base la literatura de investigación científica contemporánea, modelos de respuesta resiliente y los reactivos de la Escala de Resiliencia SV-RES, adaptados y modificados, a los que respondieron 909 profesionales de la salud. Se realizaron pruebas de distribución, análisis factorial y consistencia interna. Resultados Se obtuvo una escala conformada por 28 reactivos agrupados en seis factores con consistencia interna global de (α = .908) y una varianza explicada de 50.5%. Discusión y conclusión La Escala de Resiliencia SV-RES cuenta con propiedades psicométricas adecuadas que la hacen apropiada para medir la capacidad de resiliencia en profesionales de la salud hospitalaria de México.

RESUMO

BACKGROUND: Peripheral arterial disease (PAD) is a common and highly morbid disease. Although there have been recent advancements in the endovascular modalities to treat PAD, comparisons of these strategies, especially in the popliteal region, remain underinvestigated. The objective of this study was to compare midterm outcomes in patients with PAD undergoing treatment with both novel and SS compared with drug-coated balloon (DCB) angioplasty. METHODS: All patients at a multi-institution health system treated for PAD in the popliteal region from 2011 to 2019 were identified. Presenting features, operative details, and outcomes were included in the analysis. Patients who underwent popliteal revascularization with stents were compared with DCB. SS were compared separately with novel dedicated stents. Two-year primary patency was the primary outcome. RESULTS: We included 408 patients (72.7 ± 11.8 years old; 57.1% men) in the analysis. There were 221 (54.7%) patients who underwent popliteal stenting and 187 (45.3%) who underwent popliteal DCB. There were high rates of tissue loss in both groups (57.9% vs 50.8%; P = .14). Stented patients had longer lesions (112.4 ± 3.2 vs 100.2 ± 5.8 mm; P = .03) and higher rates of concomitant superficial femoral artery treatment (88.2% vs 39.6%; P < .01). Chronic total occlusions accounted for the majority of lesions treated (stent 62.4%, DCB 64.2%). Perioperative complications were similar between groups. Primary patency for the stented group was higher at two years than the DCB group (61.0% vs 46.1%; P = .03). When evaluating stented patients only, SS had higher 2-year patency than novel stents in the popliteal segment (69.6% vs 51.4%; P = .04). On multivariable analysis, stenosis, as opposed to chronic total occlusion, was associated with improved patency (hazard ratio, 0.49; 95% confidence interval, 0.25-0.96; P = .04), whereas novel stents were associated with worse primary patency (hazard ratio, 2.01; 95% confidence interval, 1.09-3.73; P = .03). CONCLUSIONS: In a population of patients with severe vascular disease, stents do not have inferior patency and limb salvage rates compared with DCB angioplasty when treating the popliteal region. For patients with advanced vascular disease, and especially tissue loss, stents and DCB are both beneficial when treating popliteal lesions.

El análisis estadístico se realizó con t de Student y exacta de Fisher. Resultados: se incluyeron 54 pacientes aleatorizados en dos grupos: dexmedetomidina y control. El 81.5% de los sujetos fueron mujeres, no se encontró diferencia entre los grupos en las variables demográficas. La media de la calificación EVA a los 60 minutos para el grupo dexmedetomidina fue (2.89 ± 1.9), estadísticamente inferior comparada contra el grupo control (5.78 ± 2.3) (p ˂ 0.0001). El consumo de opioides para dexmedetomidina fue (0.424 ± 0.074 μg/h) estadísticamente menor al control (0.697 ± 0.136 μg/h) (p ˂ 0.0001) con un tamaño del efecto de Cohen de 250%. Conclusiones: disminución significativa en EVA y en el consumo de opioides con el uso de dexmedetomidina intranasal en colecistectomía laparoscópica.

Abstract: Introduction: dexmedetomidine is and useful adjuvant agent in the perioperative anesthetic management associated to nasal administration with minimum adverse effects. Material and methods: a randomized, controlled, double blind, clinical trial was carried out in elective patients undergoing laparoscopic cholecystectomy with general anesthesia. Aim of this study was to compare the postoperative analgesic effect through visual analogue scale (VAS) and the perioperative opioid consumption. Dexmedetomidine was administrated intranasally (1 μg/kg dose) versus placebo. Statistical analysis was realized through student t and Fisher Test. Results: 54 patients were randomized in two groups: dexmedetomidine vs control. Not significant differences were found between both groups in demographic variables but 81.5% were women. Mean of VAS score at 60 minutes was significantly inferior (2.89 ± 1.9) versus control group (5.78 ± 2.3) (p ˂ 0.0001). Mean of opioids consumption in dexmedetomidine group (0.424 ± 0.074 μg/h) was significant minor of control group (0.697 ± 0.136 μg/h) (p ˂ 0.0001). Size effect through Cohen test was 250%. Conclusion: statistically decrease in VAS and in opioid consumption was observed using dexmedetomidine nasally in laparoscopic cholecystectomy.

RESUMO

This study investigated the role of attentional resources in processing emotional faces in working memory (WM). Participants memorised two face arrays with the same emotion but different identities and were required to judge whether the test face had the same identity as one of the previous faces. Concurrently during encoding and maintenance, a sequence of high- or low-pitched tones (high load) or white noise bursts (low load) was presented, and participants were required to count how many low-tones were heard. Experiments 1 and 2 used an emotional and neutral test face, respectively. The results revealed a significant WM impairment for sad and angry faces in the high-load versus low-load condition but not for happy faces. In Experiment 1, participants remembered happy faces better than other emotional faces. In contrast, Experiment 2 showed that performance was poorer for happy than sad faces but not for angry faces. This evidence suggests that depleting attentional resources has less impact on WM for happy faces than other emotional faces, but also that differential effects on WM for emotional faces depend on the presence or absence of emotion in the probe face at retrieval.

RESUMO

Delayed diagnosis and a lack of adequate care for people with autism spectrum disorder (ASD) are related to worse outcomes and quality of life. This study aimed to identify the profile of service use, barriers to access care, and factors related to those barriers in Brazilian families with children with ASD. A total of 927 families with children with ASD (3-17 years) from five Brazilian regions completed an online version of the Caregivers Needs Survey. Results showed that the most used services were behavioral interventions and pharmacotherapy, while the most used professionals were neurologists, nutritionists, speech therapists, psychiatrists, psychologists, and pediatricians. The main barriers included waiting lists, costs, and the absence of services or treatment. Service use varied according to age, the region of residence, type of health care system used, and the parents/caregivers' education. Access to behavioral interventions was more frequent among users of the private system/health insurance and families whose caregivers had higher education. The absence of specialized services/treatments was less frequent among residents of state capitals and families whose caregivers had higher levels of education. This study highlights how families with children/adolescents with ASD in Brazil face significant barriers to access care related to sociodemographic factors.
