RESUMO

Dry pea (Pisum sativum L.) is a cool-season food legume rich in protein (20-25%). With increasing health and ecosystem awareness, organic plant-based protein demand has increased; however, the protein quality of organic dry pea has not been well studied. This study determined the genetic variation of individual amino acids (AAs), total AAs (liberated), total protein, and in vitro protein digestibility of commercial dry pea cultivars grown in organic on-farm fields to inform the development of protein-biofortified cultivars. Twenty-five dry pea cultivars were grown in two USDA-certified organic on-farm locations in South Carolina (SC), USA, for two years (two locations in 2019 and one in 2020). The concentrations of most individual AAs (15 of 17) and the total AA concentration significantly varied with dry pea cultivar. In vitro protein digestibility was not affected by the cultivar. Seed total AA and protein for dry pea ranged from 11.8 to 22.2 and 12.6 to 27.6 g/100 g, respectively, with heritability estimates of 0.19 to 0.25. In vitro protein digestibility and protein digestibility corrected AA score (PDCAAS) ranged from 83 to 95% and 0.18 to 0.64, respectively. Heritability estimates for individual AAs ranged from 0.08 to 0.42; principal component (PCA) analysis showed five significant AA clusters. Cultivar Fiddle had significantly higher total AA (19.6 g/100 g) and digestibility (88.5%) than all other cultivars. CDC Amarillo and Jetset were significantly higher in cystine (Cys), and CDC Inca and CDC Striker were significantly higher in methionine (Met) than other cultivars; CDC Spectrum was the best option in terms of high levels of both Cys and Met. Lysine (Lys) concentration did not vary with cultivar. A 100 g serving of organic dry pea provides a significant portion of the recommended daily allowance of six essential AAs (14-189%) and daily protein (22-48%) for an average adult weighing 72 kg. Overall, this study shows organic dry pea has excellent protein quality, significant amounts of sulfur-containing AAs and Lys, and good protein digestibility, and thus has good potential for future plant-based food production. Further genetic studies are warranted with genetically diverse panels to identify candidate genes and target parents to develop nutritionally superior cultivars for organic protein production.

RESUMO

Early relational health between caregivers and children is foundational for child health and well-being. Children and caregivers are also embedded within multiple systems and sectors, or a "child-serving ecosystem", that shapes child development. Although the COVID-19 pandemic has made this embeddedness abundantly clear, systems remain siloed and lack coordination. Fostering relational health amongst layers of this ecosystem may be a way to systematically support young children and families who are facing adversity. We integrate theory, examples, and empirical findings to develop a conceptual model informed by infant mental health and public health frameworks that illustrates how relational health across the child-serving ecosystem may promote child health and well-being at a population level. Our model articulates what relational health looks like across levels of this ecosystem from primary caregiver-child relationships, to secondary relationships between caregivers and child-serving systems, to tertiary relationships among systems that shape child outcomes directly and indirectly. We posit that positive relational health across levels is critical for promoting child health and well-being broadly. We provide examples of evidence-based approaches that address primary, secondary, and tertiary relational health, and suggest ways to promote relational health through cross-sector training and psychoeducation in the science of early development. This model conceptualizes relational health across the child-serving ecosystem and can serve as a template for promoting child health and well-being in the context of adversity.


La salud de la temprana relación entre quienes prestan cuidado y los niños es fundamental para la salud y el bienestar del niño. Los niños y quienes les cuidan forman parte de múltiples sistemas y sectores, o un "ecosistema de servicio al niño," que moldea el desarrollo del niño. Aunque la pandemia del COVID-19 ha demostrado abundante y claramente esta pertenencia, los sistemas permanecen aislados y les hace falta coordinación. Fomentar la salud de la relación entre las capas del ecosistema pudiera ser una manera de apoyar sistemáticamente a los niños pequeños y familias que se enfrentan con situaciones adversas. Presentamos un modelo conceptual con base en marcos de trabajo de la salud mental infantil y la salud pública que ilustra cómo la salud de la relación a lo largo del ecosistema de servicio al niño pudiera promover el desarrollo del niño al nivel de grupo de población. Nuestro modelo articula cómo aparece la salud de la relación a lo largo de los niveles del ecosistema desde las relaciones entre quien presta el cuidado primario y el niño, hasta las relaciones secundarias entre quienes prestan el cuidado y loa sistemas de servicio al niño, y las relaciones terciarias entre sistemas que amoldan directa e indirectamente los resultados en el niño. Una positiva salud de la relación a través de todos los niveles es esencial para promover la salud y el bienestar del niño de manera amplia. Describimos ejemplos específicos de salud de la relación primaria, secundaria y terciaria, y sugerimos maneras de promover la salud de la relación a través del entrenamiento intersectorial y la educación sicológica dentro de la ciencia del desarrollo temprano. Este modelo conceptualiza la salud de la relación a lo largo del ecosistema de servicio al niño y puede ser un esquema patrón para promover el desarrollo del niño dentro del contexto de situaciones adversas.


La Santé Relationnelle Précoce entre les personnes prenant soin des enfants et les enfants est fondamentale pour la santé de l'enfant et son bien-être. Les enfants et les personnes prenant soin d'eux sont encastrés dans de multiples systèmes et des secteurs, ou un « écosystème ¼ servant l'enfant qui forme le développement de l'enfant. Bien que la pandémie du Covid19 ait rendu cet encastrement très clair, les systèmes demeurent compartimentés et manquent de coordination. Cultiver la santé relationnelle au sein des couches de l'écosystème pourrait s'avérer être une manière de soutenir des jeunes enfants et les familles faisant face aux obstacles. Nous présentons un modèle conceptuel informé par les structures de la santé mentale du nourrisson et de la santé publique qui illustre la manière dont la santé relationnelle au travers de l'écosystème servant les enfants peut promouvoir le développement de l'enfant au niveau de la population. Notre modèle articule ce à quoi la santé relationnelle ressemble au travers des niveaux de l'écosystème, des relations entre la personne principale qui s'occupe de l'enfant et l'enfant aux relations secondaires entre les personnes prenant soin de l'enfant et les systèmes servant l'enfant, jusqu'aux relations tertiaires entres les systèmes qui donnent forme aux résultats directement et indirectement. Une santé relationnelle positive au travers de tous les niveaux est critique pour la promotion de la santé de l'enfant et de son bien-être en général. Nous décrivons des exemples spécifiques de santé relationnelle primaire, secondaire et tertiaire, et suggérons des manières de promouvoir la santé relationnelle au travers de la formation entre secteurs et de la psychoéducation dans la science du développement précoce. Ce modèle conceptualise la santé relationnelle au travers de l'écosystème servant l'enfant et peut servir de modèle pour la promotion du développement de l'enfant dans le contexte de l'adversité.

RESUMO

A primary criticism of organic agriculture is its lower yield and nutritional quality compared to conventional systems. Nutritionally, dry pea (Pisum sativum L.) is a rich source of low digestible carbohydrates, protein, and micronutrients. This study aimed to evaluate dry pea cultivars and advanced breeding lines using on-farm field selections to inform the development of biofortified organic cultivars with increased yield and nutritional quality. A total of 44 dry pea entries were grown in two USDA-certified organic on-farm locations in South Carolina (SC), United States of America (USA) for two years. Seed yield and protein for dry pea ranged from 61 to 3833 kg ha-1 and 12.6 to 34.2 g/100 g, respectively, with low heritability estimates. Total prebiotic carbohydrate concentration ranged from 14.7 to 26.6 g/100 g. A 100-g serving of organic dry pea provides 73.5 to 133% of the recommended daily allowance (%RDA) of prebiotic carbohydrates. Heritability estimates for individual prebiotic carbohydrates ranged from 0.27 to 0.82. Organic dry peas are rich in minerals [iron (Fe): 1.9-26.2 mg/100 g; zinc (Zn): 1.1-7.5 mg/100 g] and have low to moderate concentrations of phytic acid (PA:18.8-516 mg/100 g). The significant cultivar, location, and year effects were evident for grain yield, thousand seed weight (1000-seed weight), and protein, but results for other nutritional traits varied with genotype, environment, and interactions. "AAC Carver," "Jetset," and "Mystique" were the best-adapted cultivars with high yield, and "CDC Striker," "Fiddle," and "Hampton" had the highest protein concentration. These cultivars are the best performing cultivars that should be incorporated into organic dry pea breeding programs to develop cultivars suitable for organic production. In conclusion, organic dry pea has potential as a winter cash crop in southern climates. Still, it will require selecting diverse genetic material and location sourcing to develop improved cultivars with a higher yield, disease resistance, and nutritional quality.

RESUMO

BACKGROUND: Hypoparathyroidism (HypoPT) is a common sequela of anterior neck surgeries. While the acute risks of HypoPT are well known, emerging evidence is beginning to define the risks chronic HypoPT poses to patients. This meta-analysis aims to evaluate that risk and give more insight into its consequences. METHODS: A systematic review and meta-analysis were performed, searching EMBASE, Web of Science, and Scopus for studies published up to July 1, 2020 and reported following PRISMA guidelines. Pooled analysis was estimated using the Mantel-Haenszel method and a random-effects model. A sub-analysis of the pooled data for each morbidity was performed and demonstrated in forest plots. RESULTS: Patients with postsurgical chronic HypoPT had a high risk of cardiac morbidities [odds ratio (OR) =1.43; 95% confidence interval (95% CI): 1.21 to 1.70; P<0.001] in the absence of elevated risk of cardiac arrhythmias (OR =1.35, 95% CI: 0.96 to 1.79, P=0.08). Analysis also showed higher odds of developing renal disease (OR =4.85, 95% CI: 3.54 to 6.67, P<0.001), renal stones (OR =3.86, 95% CI: 1.81 to 8.23, P<0.001), seizures (OR =2.41, 95% CI: 1.66 to 3.5, P<0.001), mental health problems (OR =1.46, 95% CI: 1.21 to 1.77, P<0.001), and infections (OR =1.51, 95% CI: 1.28 to 1.78, P<0.001). Conversely, HypoPT has no effect on mortality risk (OR =1.19, 95% CI: 0.96 to 1.49, P=0.12). CONCLUSIONS: Postsurgical HypoPT patients are vulnerable to a variety of medical and psychiatric diseases. This meta-analysis should guide surgeons in preoperative counseling and postoperative care for patients undergoing anterior neck surgeries.

RESUMO

Clinically approved neural stimulators are limited by battery requirements, as well as by their large size compared with the stimulation targets. Here, we describe a wireless, leadless and battery-free implantable neural stimulator that is 1.7 mm3 and that incorporates a piezoceramic transducer, an energy-storage capacitor and an integrated circuit. An ultrasonic link and a hand-held external transceiver provide the stimulator with power and bidirectional communication. The stimulation protocols were wirelessly encoded on the fly, reducing power consumption and on-chip memory, and enabling protocol complexity with a high temporal resolution and low-latency feedback. Uplink data indicating whether stimulation occurs are encoded by the stimulator through backscatter modulation and are demodulated at the external transceiver. When embedded in ex vivo porcine tissue, the integrated circuit efficiently harvested ultrasonic power, decoded downlink data for the stimulation parameters and generated current-controlled stimulation pulses. When cuff-mounted and acutely implanted onto the sciatic nerve of anaesthetized rats, the device conferred repeatable stimulation across a range of physiological responses. The miniaturized neural stimulator may facilitate closed-loop neurostimulation for therapeutic interventions.

RESUMO

Advances in minimally-invasive, distributed biological interface nodes enable possibilities for networks of sensors and actuators to connect the brain with external devices. The recent development of the neural dust sensor mote has shown that utilizing ultrasound backscatter communication enables untethered sub-mm neural recording devices. These implanted sensor motes require a wearable external ultrasound interrogation device to enable in-vivo, freely-behaving neural interface experiments. However, minimizing the complexity and size of the implanted sensors shifts the power and processing burden to the external interrogator. In this paper, we present an ultrasound backscatter interrogator that supports real-time backscatter processing in a rodent-wearable, completely wireless device. We demonstrate a generic digital encoding scheme which is intended for transmitting neural information. The system integrates a front-end ultrasonic interface ASIC with off-the-shelf components to enable a highly compact ultrasound interrogation device intended for rodent neural interface experiments but applicable to other model systems.

RESUMO

BACKGROUND: The controversy over whether certain pediatric craniofacial operations primarily address "functional" versus "aesthetic" goals has fostered tensions among insurance companies, patients and families, and treatment teams. The authors posit that such operations have objectives and outcomes that can be categorized as "functionally aesthetic" and describe the empirical basis for this assertion. Furthermore, the authors apply this concept to the difficult surgical decision-making process associated with treating children with severe cognitive impairments. METHODS: When patients have severe cognitive impairments, the social benefits of treatment may be less clear than for other patients, increasing the complexity of surgery decision-making. The authors discuss the nature of cognitive impairment, its prevalence in patients with craniofacial anomalies, links between social functioning and both cognitive development and appearance, and the importance of social integration for psychological and cognitive functioning. Special issues involved in working with cognitively impaired children are covered, including parent and patient expectations for surgical outcome and the difficulties involved in pain assessment and control. Potential linkages are described for craniofacial surgery, appearance, social functioning, and cognitive development. CONCLUSIONS: A craniofacial operation directed at reconstruction of a congenital defect in a child should not be dismissed as simply and purely cosmetic. The authors document and outline the potential ethical issues and social and cognitive benefits that should be considered by insurance companies, patients and families, and treatment teams when determining treatment options for cognitively impaired children with craniofacial anomalies.

RESUMO

California Verbal Learning Test-Children's Version (CVLT-C) indices have been shown to be sensitive to the neurocognitive effects of traumatic brain injury (TBI). The effects of TBI on the learning process were examined with a growth curve analysis of CVLT-C raw scores across the 5 learning trials. The sample with history of TBI comprised 86 children, ages 6-16 years, at a mean of 10.0 (SD=19.5) months postinjury; 37.2% had severe injury, 27.9% moderate, and 34.9% mild. The best-fit model for verbal learning was with a quadratic function. Greater TBI severity was associated with lower rate of acquisition and more gradual deceleration in the rate of acquisition. Intelligence test index scores, previously shown to be sensitive to severity of TBI, were positively correlated with rate of acquisition. Results provide evidence that the CVLT-C learning slope is not a simple linear function and further support for specific effects of TBI on verbal learning.

RESUMO

The purpose of this study was to examine parents' perceptions of the health and health-related quality of life in a series of children and adolescents with cleft and other craniofacial anomalies. The subjects for this prospective study were a consecutive series of 54 children and adolescents presenting to an outpatient craniofacial anomalies surgery clinic, ages 5 to 18 years (mean, 8.9 +/- 4.2 years), 50 percent with cleft lip and/or palate, 9 percent synostotic (two coronal, two bicoronal, and one sagittal), 17 percent syndromic (two Apert, one Crouzon, one Noonan, two Goldenhar, two Smith-Lemli-Opitz, and one brachio-oto-renal), and 24 percent with other diagnoses. Subjects were divided into two groups, those with primary cleft lip and/or palate and those with other craniofacial anomalies. Health and health-related quality of life were assessed with the Child Health Questionnaire version PF28, a reliable and valid 28-Likert-item questionnaire completed by parents and yielding physical and psychosocial status scale scores. Physical and psychosocial scale scores largely fell within normal limits for the subset of children with cleft lip and/or palate. There were significant group differences in parents' ratings of global health status, with greater health concerns noted in the non-cleft lip and/or palate group. There were no significant associations between either age or sex and physical or psychosocial health. Physical health, behavior, and psychological status were highly correlated. Using a health status and quality-of-life assessment instrument, findings indicate perceived health differences between groups with and without primary cleft lip and/or palate. In contrast to normative data with the Child Health Questionnaire, findings suggest that there is a significant association between perceived physical health and psychosocial adjustment in the population of children with craniofacial anomalies. The significant perceived health needs of the non-cleft lip and/or palate group and the association between physical health and psychological adjustment highlight the importance of the interdisciplinary nature of craniofacial teams.
