El objetivo de este trabajo de investigación es relacionar el estado nutricional con los hábitos alimentarios de los estudiantes de
Educación Física de la Universidad Nacional Enrique Guzmán y Valle.
Metodología: La investigación es de tipo no experimental descriptivo con diseño
correlacional, la muestra fue probabilística de tipo aleatorio simple, cuyo tamaño fue 184
estudiantes de la especialidad mencionada. Se realizaron medidas antropométricas como la
talla y peso para calcular el ÍMC y clasificarlo el estado nutricional. Se empleó un
cuestionario de hábitos alimentarios que está compuesto por 23 ítems, este instrumento fue
validado mediante un juicio de expertos. Los datos fueron procesados mediante la estadística
descriptiva e inferencial. Se determinó la correlación mediante el Rho de Spearman.
Resultados: Se identificó que el 67,9% de los estudiantes de educación física tenían un
estado nutricional normal, el 28,8% sobrepeso, asimismo el 3,3% obesidad y 0,0% delgadez.
Por lo que consideramos al estado nutricional como preocupante. El 63,5% de los
estudiantes respondieron que no en costumbres alimentarias y 57,3% respondió que sí en
conducta alimentaria; por lo tanto, la dimensión costumbres alimentarias de la variable
hábitos alimentarios no presentan aceptación. Conclusión: Existe relación significativa entre
los hábitos alimentarios y el estado nutricional de los estudiantes de educación física de la
Universidad Nacional Enrique Guzmán y Valle.The objective of this research work is to relate the nutritional status with the eating habits of the Physical Education students of the Enrique Guzmán y Valle National University. Methodology: The research is of a non-experimental descriptive type with a correlational design, the sample was probabilistic of a simple random type, whose size was 184 students of the aforementioned specialty. Anthropometric measurements such as height and weight were taken to calculate the BMI and classify the nutritional status. A questionnaire on eating habits was used, which is made up of 23 items; this instrument was validated by expert judgment. Data were processed using descriptive and inferential statistics. Correlation was determined using Spearman's Rho. Results: It was identified that 67.9% of physical education students had a normal nutritional status, 28.8% overweight, likewise 3.3% obesity and 0.0% thinness. Therefore, we consider the nutritional status as worrisome. 63.5% of the students answered no in eating habits and 57.3% answered yes in eating behavior; therefore, the eating habits dimension of the eating habits variable is not accepted. Conclusion: There is a significant relationship between eating habits and the nutritional status of physical education students at the Enrique Guzmán y Valle National University.ChosicaEducación Alimentaria y Nutrición en la ComunidadEscuela Profesional de Nutrición Human
Heme oxygenase-1 and 2 common genetic variants and risk for restless legs syndrome
Varios neurotransmisores, neuropatológicos, neuroimagen, y los datos experimentales, sugieren que la deficiencia de hierro juega un papel importante en la fisiopatología del síndrome de piernas inquietas (RLS). HMOX (Hemeoxygenases) es un importante mecanismo de defensa contra el estrés oxidativo, principalmente a través de la degradación del hemo a biliverdin, libre de hierro, y monóxido de carbono. Hemos analizado si los genes HMOX1 y HMOX2 están relacionados con el riesgo de desarrollar el síndrome de piernas inquietas. Se analizó la distribución de genotipos y las frecuencias alélicas de los HMOX1 rs2071746, HMOX1 rs2071747, HMOX2 rs2270363 y rs1051308 HMOX2 SNPs, así como la presencia de variaciones de número de copia (CNVs) de estos genes en 205 sujetos RLS y 445 controles sanos. Las frecuencias de rs2071746 genotipo TT y R2071746T variante alélica fueron significativamente inferiores en los pacientes de SPI que en controles, aunque los otros 3 SNPs estudiados RLS no difirió entre pacientes y controles. Ninguno de los polimorfismos estudiados influyeron en el inicio de la enfermedad, la gravedad de la RLS, historia familiar de SPI, la ferritina sérica, o respuesta a agonistas dopaminérgicos, clonazepam o GABAergic drogas. El presente estudio sugiere una débil asociación entre el polimorfismo rs2071746 HMOX1 y el riesgo de desarrollar el SPI en la población española.Several neurochemical, neuropathological, neuroimaging, and experimental data, suggest that iron deficiency plays an important role in the pathophysiology of restless legs syndrome (RLS). Hemeoxygenases (HMOX) are an important defensive mechanism against oxidative stress, mainly through the degradation of heme to biliverdin, free iron, and carbon monoxide. We analyzed whether HMOX1 and HMOX2 genes are related with the risk to develop RLS. We analyzed the distribution of genotypes and allelic frequencies of the HMOX1 rs2071746, HMOX1 rs2071747, HMOX2 rs2270363, and HMOX2 rs1051308 SNPs, as well as the presence of Copy number variations (CNVs) of these genes in 205 subjects RLS and 445 healthy controls. The frequencies of rs2071746TT genotype and rs2071746T allelic variant were significantly lower in RLS patients than that in controls, although the other 3 studied SNPs did not differ between RLS patients and controls. None of the studied polymorphisms influenced the disease onset, severity of RLS, family history of RLS, serum ferritin levels, or response to dopaminergic agonist, clonazepam or GABAergic drugs. The present study suggests a weak association between HMOX1 rs2071746 polymorphism and the risk to develop RLS in the Spanish population.• Instituto de Salud Carlos III, Fondo de Investigación Sanitaria: Ayudas PI12/00241, PI12/00324 y RETICS RD12/0013/0002

Association between vitamin D receptor rs731236 (Taq1) polymorphism and risk for restless legs syndrome in the Spanish caucasian population
Varios trabajos recientes sugieren un posible papel de la deficiencia de vitamina D en la etiología o el síndrome de las piernas inquietas (RLS). Hemos analizado la posible relación de 2 polimorfismos de un solo nucleótido (SNP) en el receptor de la vitamina D3 (GEN VDR) con el riesgo de SPI. Hemos estudiado la variante alélica genotipo y frecuencias de VDR rs2228570 y rs731236 VDR SNPs en 205 RLS pacientes y 445 controles sanos mediante un ensayo TaqMan. Las frecuencias de los rs731236AAgenotype y la variante alélica rs731236un SPI fue significativamente inferior en los pacientes que en los controles (P<0,005 y 0,01, respectivamente). El síndrome de las piernas inquietas pacientes portadoras de la variante alélica rs731236G había una edad temprana en el inicio, y los portadores del genotipo GG731236rs tuvieron mayor severidad de RLS, aunque estos datos desaparecieron después de los análisis multivariados. Ninguno de los SNPs estudiados estaba relacionada con la positividad de la historia familiar de SPI. Estos resultados sugieren una modesta, pero significativa asociación entre rs731236 VDR SNP y el riesgo de síndrome de piernas inquietas.Several recent works suggest a possible role of vitamin D deficiency in the etiology or restless legs syndrome (RLS). We analyzed the possible relationship of 2 common single nucleotide polymorphisms (SNPs) in the vitamin D3 receptor (VDR) gene with the risk for RLS. We studied the genotype and allelic variant frequencies of VDR rs2228570 and VDR rs731236 SNPs in 205 RLS patients and 445 healthy controls using a TaqMan essay. The frequencies of the rs731236AAgenotype and the allelic variant rs731236A were significantly lower in RLS patients than in controls (P<0.005 and<0.01, respectively). Restless legs syndrome patients carrying the allelic variant rs731236G had an earlier age at onset, and those carrying the rs731236GG genotype had higher severity of RLS, although these data disappeared after multivariate analyses. None of the SNPs studied was related with the positivity of family history of RLS. These results suggest a modest, but significant association between VDR rs731236 SNP and the risk for RLS.• Instituto de Salud Carlos III, Madrid, Fondo de Investigación Sanitaria: Ayudas PI12/00241, PI12/00324, y RETICS RD12/0013/0002

Anti-Spike antibodies 3 months after SARS-CoV-2 mRNA vaccine booster dose in patients on hemodialysis: the prospective SENCOVAC study
Background: Patients on hemodialysis are at high-risk for complications derived from coronavirus disease 2019 (COVID-19). The present analysis evaluated the impact of a booster vaccine dose and breakthrough severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections on humoral immunity 3 months after the booster dose. Methods: This is a multicentric and prospective study assessing immunoglobulin G anti-Spike antibodies 6 and 9 months after initial SARS-CoV-2 vaccination in patients on hemodialysis that had also received a booster dose before the 6-month assessment (early booster) or between the 6- and 9-month assessments (late booster). The impact of breakthrough infections, type of vaccine, time from the booster and clinical variables were assessed. Results: A total of 711 patients [67% male, median age (range) 67 (20-89) years] were included. Of these, 545 (77%) received an early booster and the rest a late booster. At 6 months, 64 (9%) patients had negative anti-Spike antibody titers (3% of early booster and 29% of late booster patients, P =. 001). At 9 months, 91% of patients with 6-month negative response had seroconverted and there were no differences in residual prevalence of negative humoral response between early and late booster patients (0.9% vs 0.6%, P =. 693). During follow-up, 35 patients (5%) developed breakthrough SARS-CoV-2 infection. Antibody titers at 9 months were independently associated with mRNA-1273 booster (P =. 001), lower time from booster (P =. 043) and past breakthrough SARS-CoV-2 infection (P <. 001). Conclusions: In hemodialysis patients, higher titers of anti-Spike antibodies at 9 months were associated with mRNA-1273 booster, lower time from booster and past breakthrough SARS-CoV-2 infectionThe present project has been supported by Fresenius Medical Care, Diaverum, Vifor Pharma, Vircell, Fundación Renal Iñigo Álvarez de Toledo and ISCIII FEDER funds RICORS2040 (RD21/0005
Genomic Ancestry, CYP2D6, CYP2C9, and CYP2C19 Among Latin Americans
We present the distribution of CYP2D6, CYP2C9, and CYP2C19 variants and predicted phenotypes in 33 native and
admixed populations from Ibero-America (n > 6,000) in the context of genetic ancestry (n = 3,387). Continental
ancestries are the major determinants of frequencies of the increased-activity allele CYP2C19*17 and CYP2C19
gUMs (negatively associated with Native American ancestry), decreased-activity alleles CYP2D6*41 and CYP2C9*2
(positively associated with European ancestry), and decreased-activity alleles CYP2D6*17 and CYP2D6*29 (positively
associated with African ancestry). For the rare alleles, CYP2C9*2 and CYPC19*17, European admixture accounts
for their presence in Native American populations, but rare alleles CYP2D6*5 (null-activity), CYP2D6-multiplication
alleles (increased activity), and CYP2C9*3 (decreased-activity) were present in the pre-Columbian Americas.
The study of a broad spectrum of Native American populations from different ethno-linguistic groups show how
autochthonous diversity shaped the distribution of pharmaco-alleles and give insights on the prevalence of clinically
relevant phenotypes associated with drugs, such as paroxetine, tamoxifen, warfarin, and clopidogrel

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study
Summary
Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally.
Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies
have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of
the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income
countries globally, and identified factors associated with mortality.
Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to
hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis,
exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a
minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical
status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary
intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause,
in-hospital mortality for all conditions combined and each condition individually, stratified by country income status.
We did a complete case analysis.
Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital
diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal
malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome
countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male.
Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3).
Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income
countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups).
Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome
countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries;
p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients
combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11],
p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20
[1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention
(ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety
checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed
(ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of
parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65
[0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality.
Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome,
middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will
be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger
than 5 years by 2030
