Evaluation of the nutritional status of the elderly in a permanent geriatric stay
El proceso de envejecimiento sugiere una serie de cambios fisiológicos a nivel de los diversos órganos y sistemas provocando pérdida de la masa y fuerza conocida como sarcopenia. La desnutrición es uno de los grandes síndromes geriátricos y un factor desencadenante para fragilidad en los adultos mayores. Esto representa un factor de riesgo para institucionalización y desencadenamiento de otras morbilidades. Es por esto que la realización de un diagnóstico oportuno sobre el estado nutricional de los adultos mayores dentro de una estancia geriátrica permanente es una herramienta para la realización y evaluación de las intervenciones de enfermería para los cuidadores y los pacientes institucionalizados. El presente trabajo fue parte de la materia de Cuidado de Enfermería en la salud mental donde los estudiantes de la materia de Cuidado de Enfermería en el adulto mayor tomaron los datos a evaluar a través de 4 escalas de evaluación que fueron la escala de Braden para determinar úlceras por presión, Escala de Morse para evaluar riesgo de caídas, Mini nutricional Self MNA para evaluar estado nutricional y SARC – F que evalúa presencia de sarcopenia. Dentro de los principales resultados encontramos que los adultos mayores institucionalizados presentan desnutrición 17%, 30% riesgo de desnutrición, 45% estado nutricional normal y un 8% se negó a evaluar, en cuanto a riesgo bajo de úlceras por presión, con un poco riesgo de caídas con un 50% y 25 sin riesgo de caídas, en cuanto a la presencia de úlceras se encontró un 70% de riesgo bajo, 15% con riesgo moderado y 15 % de pacientes con alto riesgo de presentar úlceras por presión. Es por esto que la evaluación y seguimiento de la nutrición tanto de cuidadores como de personal de enfermería son cruciales para evitar compromiso en la salud del adulto mayor.The aging process suggests a series of physiological changes at the level of various organs and systems, causing loss of mass and strength known as sarcopenia. Malnutrition is one of the major geriatric syndromes and a triggering factor for frailty in older adults. This represents a risk factor for institutionalization and triggering of other morbidities. This is why making a timely diagnosis of the nutritional status of older adults within a permanent geriatric stay is a tool for carrying out and evaluating nursing interventions for caregivers and institutionalized patients. The present work was part of the subject of Nursing Care in mental health where the students of the subject of Nursing Care in the elderly took the data to be evaluated through 4 evaluation scales that were the Braden scale to determine pressure ulcers, Morse Scale to assess the risk of falls, Mini nutritional Self MNA to assess nutritional status and SARC - F that assesses the presence of sarcopenia. Among the main results we found that institutionalized older adults have 17% malnutrition, 30% risk of malnutrition, 45% normal nutritional status and 8% refused to evaluate, in terms of low risk of pressure ulcers, with a little risk of falls with 50% and 25 without risk of falls, in terms of the presence of ulcers, 70% were found to be at low risk, 15% at moderate risk and 15% of patients at high risk of presenting pressure ulcers. This is why the evaluation and follow-up of the nutrition of both caregivers and nursing staff are crucial to avoid compromising the health of the elderly

Recruiting a New Substrate for Triacylglycerol Synthesis in Plants: The Monoacylglycerol Acyltransferase Pathway
BACKGROUND: Monoacylglycerol acyltransferases (MGATs) are predominantly associated with lipid absorption and resynthesis in the animal intestine where they catalyse the first step in the monoacylglycerol (MAG) pathway by acylating MAG to form diacylglycerol (DAG). Typical plant triacylglycerol (TAG) biosynthesis routes such as the Kennedy pathway do not include an MGAT step. Rather, DAG and TAG are synthesised de novo from glycerol-3-phosphate (G-3-P) by a series of three subsequent acylation reactions although a complex interplay with membrane lipids exists. METHODOLOGY/PRINCIPAL FINDINGS: We demonstrate that heterologous expression of a mouse MGAT acyltransferase in Nicotiana benthamiana significantly increases TAG accumulation in vegetative tissues despite the low levels of endogenous MAG substrate available. In addition, DAG produced by this acyltransferase can serve as a substrate for both native and coexpressed diacylglycerol acyltransferases (DGAT). Finally, we show that the Arabidopsis thaliana GPAT4 acyltransferase can produce MAG in Saccharomyces cerevisiae using oleoyl-CoA as the acyl-donor. CONCLUSIONS/SIGNIFICANCE: This study demonstrates the concept of a new method of increasing oil content in vegetative tissues by using MAG as a substrate for TAG biosynthesis. Based on in vitro yeast assays and expression results in N. benthamiana, we propose that co-expression of a MAG synthesising enzyme such as A. thaliana GPAT4 and a MGAT or bifunctional M/DGAT can result in DAG and TAG synthesis from G-3-P via a route that is independent and complementary to the endogenous Kennedy pathway and other TAG synthesis routes
A Myb Transcription Factor of Phytophthora sojae, Regulated by MAP Kinase PsSAK1, Is Required for Zoospore Development
PsSAK1, a mitogen-activated protein (MAP) kinase from Phytophthora sojae, plays an important role in host infection and zoospore viability. However, the downstream mechanism of PsSAK1 remains unclear. In this study, the 3'-tag digital gene expression (DGE) profiling method was applied to sequence the global transcriptional sequence of PsSAK1-silenced mutants during the cysts stage and 1.5 h after inoculation onto susceptible soybean leaf tissues. Compared with the gene expression levels of the recipient P. sojae strain, several candidates of Myb family were differentially expressed (up or down) in response to the loss of PsSAK1, including of a R2R3-type Myb transcription factor, PsMYB1. qRT-PCR indicated that the transcriptional level of PsMYB1 decreased due to PsSAK1 silencing. The transcriptional level of PsMYB1 increased during sporulating hyphae, in germinated cysts, and early infection. Silencing of PsMYB1 results in three phenotypes: a) no cleavage of the cytoplasm into uninucleate zoospores or release of normal zoospores, b) direct germination of sporangia, and c) afunction in zoospore-mediated plant infection. Our data indicate that the PsMYB1 transcription factor functions downstream of MAP kinase PsSAK1 and is required for zoospore development of P. sojae
Large sub-clonal variation in <i>Phytophthora infestans</i> from recent severe late blight epidemics in India
Abstract The population structure of the Phytophthora infestans populations that caused the recent 2013–14 late blight epidemic in eastern India (EI) and northeastern India (NEI) was examined. The data provide new baseline information for populations of P. infestans in India. A migrant European 13_A2 genotype was responsible for the 2013–14 epidemic, replacing the existing populations. Mutations have generated substantial sub-clonal variation with 24 multi-locus genotypes (MLGs) found, of which 19 were unique variants not yet reported elsewhere globally. Samples from West Bengal were the most diverse and grouped alongside MLGs found in Europe, the UK and from neighbouring Bangladesh but were not linked directly to most samples from south India. The pathogen population was broadly more aggressive on potato than on tomato and resistant to the fungicide metalaxyl. Pathogen population diversity was higher in regions around the international borders with Bangladesh and Nepal. Overall, the multiple shared MLGs suggested genetic contributions from UK and Europe in addition to a sub-structure based on the geographical location within India. Our data indicate the need for improved phytosanitary procedures and continuous surveillance to prevent the further introduction of aggressive lineages of P. infestans into the country
The c4h, tat, hppr and hppd Genes Prompted Engineering of Rosmarinic Acid Biosynthetic Pathway in Salvia miltiorrhiza Hairy Root Cultures
Rational engineering to produce biologically active plant compounds has been greatly impeded by our poor understanding of the regulatory and metabolic pathways underlying the biosynthesis of these compounds. Here we capitalized on our previously described gene-to-metabolite network in order to engineer rosmarinic acid (RA) biosynthesis pathway for the production of beneficial RA and lithospermic acid B (LAB) in Salvia miltiorrhiza hairy root cultures. Results showed their production was greatly elevated by (1) overexpression of single gene, including cinnamic acid 4-hydroxylase (c4h), tyrosine aminotransferase (tat), and 4-hydroxyphenylpyruvate reductase (hppr), (2) overexpression of both tat and hppr, and (3) suppression of 4-hydroxyphenylpyruvate dioxygenase (hppd). Co-expression of tat/hppr produced the most abundant RA (906 mg/liter) and LAB (992 mg/liter), which were 4.3 and 3.2-fold more than in their wild-type (wt) counterparts respectively. And the value of RA concentration was also higher than that reported before, that produced by means of nutrient medium optimization or elicitor treatment. It is the first report of boosting RA and LAB biosynthesis through genetic manipulation, providing an effective approach for their large-scale commercial production by using hairy root culture systems as bioreactors
Calpain-5 gene variants are associated with diastolic blood pressure and cholesterol levels
BACKGROUND: Genes implicated in common complex disorders such as obesity, type 2 diabetes mellitus (T2DM) or cardiovascular diseases are not disease specific, since clinically related disorders also share genetic components. Cysteine protease Calpain 10 (CAPN10) has been associated with T2DM, hypertension, hypercholesterolemia, increased body mass index (BMI) and polycystic ovary syndrome (PCOS), a reproductive disorder of women in which isunlin resistance seems to play a pathogenic role. The calpain 5 gene (CAPN5) encodes a protein homologue of CAPN10. CAPN5 has been previously associated with PCOS by our group. In this new study, we have analysed the association of four CAPN5 gene variants(rs948976A>G, rs4945140G>A, rs2233546C>T and rs2233549G>A) with several cardiovascular risk factors related to metabolic syndrome in general population. METHODS: Anthropometric measurements, blood pressure, insulin, glucose and lipid profiles were determined in 606 individuals randomly chosen from a cross-sectional population-based epidemiological survey in the province of Segovia in Central Spain (Castille), recruited to investigate the prevalence of anthropometric and physiological parameters related to obesity and other components of the metabolic syndrome. Genotypes at the four polymorphic loci in CAPN5 gene were detected by polymerase chain reaction (PCR). RESULTS: Genotype association analysis was significant for BMI (p ≤ 0.041), diastolic blood pressure (p = 0.015) and HDL-cholesterol levels (p = 0.025). Different CAPN5 haplotypes were also associated with diastolic blood pressure (DBP) (0.0005 ≤ p ≤ 0.006) and total cholesterol levels (0.001 ≤ p ≤ 0.029). In addition, the AACA haplotype, over-represented in obese individuals, is also more frequent in individuals with metabolic syndrome defined by ATPIII criteria (p = 0.029). CONCLUSION: As its homologue CAPN10, CAPN5 seems to influence traits related to increased risk for cardiovascular diseases. Our results also may suggest CAPN5 as a candidate gene for metabolic syndrome
