RESUMEN

Deforestation is one of the most relevant transformations characterizing global environmental change in the tropics at present. There is wide consensus in pointing the context-dependent nature of tropical deforestation. In this sense, a better characterization of the phenomenon considering the social context could provide a more accurate picture of tropical deforestation. With this aim, a Q-methodology discourse analysis was conducted to characterise the different discourses that coexist in the particular region of the Paraguayan Chaco concerning the development of cattle ranching and derived deforestation. Four different discourses were identified as making sense the wide range of interests and values coexisting and clashing in the Paraguayan Chaco, namely: the Environmentalist discourse, the Business discourse, the Resigned discourse, and the Possibilist discourse. The results point that the fundamental differences between the discourses are largely explained by the different positions on three specific domains: (i) the socio-economic benefits the expansion of cattle ranching brings about; (ii) the environmental impacts the expansion of cattle ranching and the derived deforestation brings on; and, finally (iii) the degree to which an active intervention from the side of policy making to regulate the expansion of cattle ranching and to minimize possible detrimental effects is seen as necessary. The position of the different discourses in relation to these domains could help policy makers to make measures and regulations more widely accepted and followed.

RESUMEN

Whole exome and genome sequencing, coupled with refined bioinformatic pipelines, have enabled improved diagnostic yields for individuals with Mendelian conditions and have led to the rapid identification of novel syndromes. For many Mendelian neurodevelopmental disorders (NDDs), there is a lack of pre-existing model systems for mechanistic work. Thus, it is critical for translational researchers to have an accessible phenotype- and genotype-informed approach for model system selection. Single-cell RNA sequencing data can be informative in such an approach, as it can indicate which cell types express a gene of interest at the highest levels across time. For Mendelian NDDs, such data for the developing human brain is especially useful. A valuable single-cell RNA sequencing dataset of the second trimester developing human brain was produced by Bhaduri et al in 2021, but access to these data can be limited by computing power and the learning curve of single-cell data analysis. To reduce these barriers for translational research on Mendelian NDDs, we have built the web-based tool, Neurodevelopment in Trimester 2 - VIsualization of Single cell Data Online Tool (NeuroTri2-VISDOT), for exploring this single-cell dataset, and we have employed it in several different settings to demonstrate its utility for the translational research community.

RESUMEN

Hepatitis E Virus (HEV) infection is an emergent zoonotic disease of increasing concern in developed regions. HEV genotype 3 (HEV-3) is mainly transmitted through consumption of contaminated food in high-income countries and is classified into at least 13 subtypes (3a-3n), based on p-distance values from complete genomes. In Latin America, HEV epidemiology studies are very scant. Our group has previously detected HEV3 in clinical cases, swine, wild boars, captive white-collared peccaries, and spotted deer from Uruguay. Herein, we aimed to provide novel insights and an updated overview of the molecular epidemiology of zoonotic HEV in Uruguay, including data from wastewater-based surveillance studies. A thorough analysis of HEV whole genomes and partial ORF2 sequences from Uruguayan human and domestic pig strains showed that they formed a separate monophyletic cluster with high nucleotide identity and exhibited p-distance values over the established cut-off (0.093) compared with reference subtypes' sequences. Furthermore, we found an overall prevalence of 10.87% (10/92) in wastewater, where two samples revealed a close relationship with humans, and animal reservoirs/hosts isolates from Uruguay. In conclusion, a single, new HEV-3 subtype currently circulates in different epidemiological settings in Uruguay, and we propose its designation as 3o along with its reference sequence.

RESUMEN

OBJECTIVES: Polypyrimidine tract binding protein is a 57-Kda protein located in the perinucleolar compartment where it binds RNA and regulates several biological functions through the regulation of RNA splicing. Numerous research articles have been published that address the cellular network and functions of PTB and its isoforms in various disease states. METHODOLOGY: Through an extensive PubMed search, we attempt to summarize the relevant research into this biomolecule. RESULTS: Besides its roles in embryonic development, neuronal cell growth, RNA metabolism, apoptosis, and hematopoiesis, PTB can affect cancer growth via several metabolic, proliferative, and structural mechanisms. PTB overexpression has been documented in several cancers where it plays a role as a novel prognostic factor. CONCLUSION: The diverse carcinogenic effect opens an argument into its potential role in inhibitory targeted therapy.

RESUMEN

Fundamento: Las alteraciones del estado nutricional materno generalmente se relacionan con desviaciones del crecimiento fetal, que pueden detectarse por los parámetros biofísicos fetales e identifican la posible condición trófica al nacer. Objetivo: Determinar la posible relación entre los parámetros biométricos fetales, la condición trófica al nacer y el producto de acumulación de los lípidos. Metodología: Se realizó un estudio transversal en el Policlínico Chiqui Gómez Lubian del municipio Santa Clara, durante el año 2019, en una población de 253 gestantes normopeso supuestamente sanas al inicio de la gestación. La muestra no probabilística fue de 144 gestantes. Las variables de estudio fueron: producto de acumulación de los lípidos, biometría fetal y condición trófica al nacer. Se utilizaron métodos teóricos, empíricos y estadísticos. Resultados: En el segundo trimestre ningún parámetro biométrico coincidió con la condición al nacer de pequeño, mientras que para el grande coincidieron las circunferencias cefálica y abdominal. En el tercer trimestre la longitud del fémur y la circunferencia abdominal coinciden en la identificación del pequeño y del grande. El PAL se correlacionó con la circunferencia abdominal del tercer trimestre y con el peso al nacer; presentando mayor frecuencia de valores en el tercer tertil para los nacimientos grandes. Conclusiones: La circunferencia abdominal fue el parámetro biométrico con mayor coincidencia con la condición trófica al nacer, la que se asoció con valores en el tercer tertil del PAL para la detección de nacimientos grandes, relacionándose el fenotipo normopeso metabólicamente obeso con el crecimiento fetal por exceso.


Background: Maternal nutritional status disorders are usually related to fetal growth deviations, which can be detected by fetal biophysical parameters and identify the possible trophic condition at birth. Objective: To determine the possible relationship between fetal biometric parameters, the birth trophic state and lipid accumulation product. Methodology: A cross-sectional study was conducted at the Chiqui Gómez Lubian Polyclinic in Santa Clara municipality, during 2019, in a population of 253 normal-weight pregnant women who were apparently healthy at the beginning of their gestation. The non-probability sample was made up of 144 pregnant women. Study variables were: lipid accumulation product, fetal biometry and trophic condition at birth. Theoretical, empirical and statistical methods were used. Results: In the second trimester, none of the biometric parameters matched the condition at birth as a small child, while in the large one the head and abdominal circumferences matched. In the third trimester, femoral length and abdominal circumference coincide in identifying the small one and the large one. LAP correlated with third trimester abdominal circumference and birth weight, presenting higher frequency of values in the third tertile for large births. Conclusions: Abdominal circumference was the biometric parameter with the highest coincidence with trophic condition at birth, associated with values in the third tertile of the LAP for detecting large births, relating the metabolically obese normal weight phenotype with excessive fetal growth.

RESUMEN

OBJECTIVE: To evaluate the attitudes, capacities and perceived barriers associated with research among nurses and midwives of the Canary Health Service (SCS). METHODS: Descriptive observational cross-sectional study with an analytical component carried out in the different SCS departments by means of an online survey in which sociodemographic and specific variables, the Spanish version of the Attitudes towards Research and Development within Nursing Questionnaire (ATRDNQ-e) instrument and the BARRIERS scale were collected. Authorisation was obtained from the two provincial ethics committees. A descriptive and inferential analysis (Mann-Whitney U test and Kruskal-Wallis test, post hoc contrast by Dwass-Steel-Critchlow-Fligne test) was performed with JAMOVI® v.2.3.24 software. RESULTS: A total of 512 nurses and midwives with a mean age of 41.82 years participated in the study. Regarding the scores with the ATRDNQ-e instrument, the dimension with the lowest score was «Language of research¼ (mean = 3.55/SD = 0.84) and the highest «Assessment of nursing research and development of the nursing discipline¼ (mean = 4.54/SD = 0.52). The total mean score with the BARRIERS scale was 54.33 (SD = 16.52), with «Organizational characteristics¼ being the highest scoring subscale (mean = 17.25/SD = 5.90). The two highest perceived barriers were «Not enough time at work to implement new ideas¼ (mean = 2.55/SD = 1.11) and «Nursing does not have time to read research¼ (mean = 2.46/ SD = 1.11). CONCLUSIONS: SCS nurses have a positive attitude towards research, although there are some barriers where improvement actions for nursing research should be implemented.

RESUMEN

Research shows many positive effects from physical exercise. The present study examined the impact of a structured physical exercise program compared to treatment as usual on the gross motor skills of children diagnosed with autism spectrum disorder (ASD). Participants included 20 children, from 4 to 7 years old, who were assigned to two groups; an experimental group (n = 10) who received a structured physical exercise program for 60-min sessions, three times a week for eight weeks, and a control group (n = 10) who received conventional physiotherapy. Gross motor skills were assessed with the Abbreviated Development Scale -3 before and after the physical exercise program. The experimental group exhibited significant improvements in gross motor skills compared to the control group. This study suggests that structured physical exercise programs can improve gross motor skills in children with ASD.

RESUMEN

Spheroid culture systems have allowed in vitro propagation of cells unable to grow in canonical cell culturing conditions, and may capture cellular contexts that model tumor growth better than current model systems. The insights gleaned from genome-wide clustered regularly interspaced short palindromic repeat (CRISPR) screening of thousands of cancer cell lines grown in conventional culture conditions illustrate the value of such CRISPR pooled screens. It is clear that similar genome-wide CRISPR screens of three-dimensional spheroid cultures will be important for future biological discovery. Here, we present a protocol for genome-wide CRISPR screening of three-dimensional neurospheres. While many in-depth protocols and discussions have been published for more typical cell lines, few detailed protocols are currently available in the literature for genome-wide screening in spheroidal cell lines. For those who want to screen such cell lines, and particularly neurospheres, we provide a step-by-step description of assay development tests to be performed before screening, as well as for the screen itself. We highlight considerations of variables that make these screens distinct from, or similar to, typical nonspheroid cell lines throughout. Finally, we illustrate typical outcomes of neurosphere genome-wide screens, and how neurosphere screens typically produce slightly more heterogeneous signal distributions than more canonical cancer cell lines. Completion of this entire protocol will take 8-12 weeks from the initial assay development tests to deconvolution of the sequencing data.

RESUMEN

Introducción: La muerte fetal es uno de los accidentes obstétricos más difíciles de enfrentar, tanto para la paciente y su familia como para el personal de salud que atiende a la gestante. Objetivo: Identificar los factores de riesgo maternos asociados con la muerte fetal tardía en el contexto santaclareño. Métodos: Se realizó un estudio descriptivo, longitudinal y retrospectivo en el municipio Santa Clara, provincia Villa Clara, en el período comprendido de enero de 2015 a diciembre de 2019. La población estuvo conformada por 71 gestantes con fetos muertos en una etapa tardía y sus productos; en el análisis y procesamiento de los datos, se usó el software SPSS versión 20 para Windows. Resultados: Existió predominio de gestantes multíparas (56,3 %), en edad reproductiva óptima (69 %) y con uno a tres factores de riesgo (71,8 %). Conclusiones: Los factores maternos asociados con mayor frecuencia a la muerte fetal tardía pueden agruparse en: los vinculados a las enfermedades crónicas, en primer lugar la hipertensión arterial y en segundo el hipotiroidismo, y los relacionados con las afecciones del tracto genital, entre las que prevalece la vaginitis.


Introduction: fetal death is one of the most difficult obstetric accidents to face, both for patients and their families as well as for the health personnel who take care of the pregnant women. Objective: to identify the maternal risk factors associated with late fetal death in the Santa Clara context. Methods: a descriptive, longitudinal and retrospective study was carried out in Santa Clara municipality, Villa Clara province, from January 2015 to December 2019. The population consisted of 71 pregnant women with late fetal demise and their products; the SPSS software version 20.0 for Windows was used in the data processing and analysis. Results: multiparous pregnant women predominated (56.3%), in optimal reproductive age (69%) and from one to three risk factors (71.8%). Conclusions: the most frequently maternal factors associated with late fetal death can be grouped into those that were linked to chronic diseases, firstly arterial hypertension and secondly hypothyroidism, and those related to disorders of the genital tract, among which vaginitis prevails.

RESUMEN

The perinucleolar compartment (PNC) is a small nuclear body that plays important role in tumorigenesis. PNC prevalence correlates with poor prognosis and cancer metastasis. Its expression in pediatric Ewing sarcoma (EWS) has not previously been documented. In this study, we analyzed 40 EWS tumor cases from Caucasian and Hispanic patients for PNC prevalence by immunohistochemical detection of polypyrimidine tract binding protein and correlated the prevalence with dysregulated microRNA profiles. EWS cases showed staining ranging from 0 to 100%, which were categorized as diffuse (≥77%, n = 9, high PNC) or not diffuse (<77%, n = 31) for low PNC. High PNC prevalence was significantly higher in Hispanic patients from the US (n = 6, p = 0.017) and in patients who relapsed with metastatic disease (n = 4; p = 0.011). High PNC was associated with significantly shorter disease-free survival and early recurrence compared to those with low PNC. Using NanoString digital profiling, high PNC tumors revealed upregulation of eight and downregulation of 18 microRNAs. Of these, miR-320d and miR-29c-3p had the most significant differential expression in tumors with high PNC. In conclusion, this is the first study that demonstrates the presence of PNC in EWS, reflecting its utility as a predictive biomarker associated with tumor metastasis, specific microRNA profile, Hispanic ethnic origin, and poor prognosis.

RESUMEN

El TDAH es el trastorno del neurodesarrollo más diagnosticado en escolares. La evidencia indica que las funciones ejecutivas, como es el caso de la velocidad de procesamiento y la memoria de trabajo, están afectadas en estudiantes con TDAH, aunque no existe un acuerdo definitivo sobre su presencia sistemática en este trastorno. Esta investigación pretende determinar si la velocidad de procesamiento y la memoria de trabajo corresponden a variables cognitivas en el TDAH. Participaron 138 estudiantes de 10 a 17 años. Se determinó TDAH con la escala VADTRS; se evaluó velocidad de procesamiento con una tarea de rapidez grafomotora y memoria de trabajo con una tarea de dígitos. Se utilizó un diseño transversal, univariante e intersujeto para el análisis de los datos. El VADTRS detectó un grupo con TDAH (N = 97) y otro sin TDAH (N = 41). A ambos grupos se aplicaron tareas de velocidad de procesamiento y memoria de trabajo; los análisis permitieron detectar diferencias significativas en estas variables entre los grupos con y sin TDAH. El grupo con TDAH fue dividido según su presentación; no se detectaron diferencias significativas en velocidad de procesamiento; la memoria de trabajo mostró un rendimiento significativa- mente menor en las presentaciones de TDAH inatenta y combinada. La velocidad de procesamiento y la memoria de trabajo parecen distinguir entre sujetos con y sin TDAH, la velocidad de procesamiento no parece distinguir entre presentaciones y la memoria de trabajo aparece alterada en aquellas presentaciones en que el componente atencional es definitorio


ADHD is the most commonly diagnosed neurodevelopmental disorder in schoolchildren. Evidence indicates that executive functions, such as processing speed and working memory, are affected in students with ADHD, although there is no definitive agreement on their sys- tematic presence in this disorder. This research aims to determine whether processing speed and working memory correspond to cognitive variables in ADHD. A total of 138 students aged 10 to 17 years participated. ADHD was determined with the VADTRS scale; processing speed was assessed with a graphomotor speed task and working memory with a digit task. A cross-sectional, univariate, intersubject design was used for data analy- sis. The VADTRS detected one group with ADHD (N = 97) and one without ADHD (N = 41). Processing speed and working memory tasks were applied to both groups; analyses detected significant differences in these variables between the ADHD and non- ADHD groups. The ADHD group was divided according to presentation; no significant differences were detected in processing speed; working memory showed significantly lower performance in the inattentive and combined ADHD presentations. Processing speed and working memory appear to distinguish between subjects with and without ADHD, processing speed does not appear to distinguish between presentations, and working memory appears impaired in those presentations in which the attentional component is defining.

RESUMEN

SARS-CoV-2 surveillance of viral populations in wastewater samples is recognized as a useful tool for monitoring epidemic waves and boosting health preparedness. Next generation sequencing of viral RNA isolated from wastewater is a convenient and cost-effective strategy to understand the molecular epidemiology of SARS-CoV-2 and provide insights on the population dynamics of viral variants at the community level. However, in low- and middle-income countries, isolated groups have performed wastewater monitoring and data has not been extensively shared in the scientific community. Here we report the results of monitoring the co-circulation and abundance of variants of concern (VOCs) of SARS-CoV-2 in Uruguay, a small country in Latin America, between November 2020-July 2021 using wastewater surveillance. RNA isolated from wastewater was characterized by targeted sequencing of the Receptor Binding Domain region within the spike gene. Two computational approaches were used to track the viral variants. The results of the wastewater analysis showed the transition in the overall predominance of viral variants in wastewater from No-VOCs to successive VOCs, in agreement with clinical surveillance from sequencing of nasal swabs. The mutations K417T, E484K and N501Y, that characterize the Gamma VOC, were detected as early as December 2020, several weeks before the first clinical case was reported. Interestingly, a non-synonymous mutation described in the Delta VOC, L452R, was detected at a very low frequency since April 2021 when using a recently described sequence analysis tool (SAM Refiner). Wastewater NGS-based surveillance of SARS-CoV-2 is a reliable and complementary tool for monitoring the introduction and prevalence of VOCs at a community level allowing early public health decisions. This approach allows the tracking of symptomatic and asymptomatic individuals, who are generally under-reported in countries with limited clinical testing capacity. Our results suggests that wastewater-based epidemiology can contribute to improving public health responses in low- and middle-income countries.

RESUMEN

Introducción: La preeclampsia-eclampsia es una de las principales causas de morbimortalidad materna y perinatal. Objetivos: Determinar el riesgo aterogénico en la preeclampsia precoz y tardía. Método: Estudio descriptivo de corte transversal en gestantes que ingresaron en el hospital materno con diagnóstico de preeclampsia agravada entre los años 2010 ­ 2019. La muestra quedó constituida por 506 mujeres, que se subdividieron en precoz (menos de 34 semanas) y tardía (con 34 y más). Se determinó riesgo aterogénico en el momento del diagnóstico de preeclampsia grave y se clasificó a las gestantes según riesgo cardio metabólico usando el método multivariante de clasificación: técnica de conglomerados en dos fases. Las variables utilizadas para el riesgo aterogénico fueron los índices de Castelli y proaterogénico a partir del cociente CT/cHDL. Resultados: Con predominio en edad fértil, con una media de 27,3 años, en la preeclampsia precoz la media resulto 30,6 semanas y en la preeclampsia tardía 37,6 semanas. En los antecedentes patológicos se encontró la multiparidad en 211 gestantes, seguido de la Hipertensión arterial crónica en 207. Del total de las 506 pacientes, 488 tienen un riesgo moderado y máximo (419 (82,8%) máximo riesgo aterogénico y 69(13,6%) riesgo moderado) con un marcado predominio en el grupo de preeclampsia de aparición tardía. Conclusiones: Pertenecen generalmente al grupo de edades reproductivas, la mayoría son multíparas, y la hipertensión arterial crónica es uno de los antecedentes más frecuentes encontrados. El riesgo aterogénico máximo y moderado predomino en la mayoría de las mujeres con preeclampsia agravada sobre todo en la aparición tardía. (provisto por Infomedic International)


Introduction: Preeclampsia-eclampsia is one of the main causes of maternal and perinatal morbidity and mortality. Objectives: To determine the atherogenic risk in early and late preeclampsia. Methods: Descriptive cross-sectional study of pregnant women admitted to the maternity hospital with a diagnosis of aggravated preeclampsia between 2010 and 2019. The sample consisted of 506 women, who were subdivided into early (less than 34 weeks) and late (34 weeks and older). Atherogenic risk was determined at the time of diagnosis of severe preeclampsia and the pregnant women were classified according to cardio-metabolic risk using the multivariate method of classification: two-stage clustering technique. The variables used for atherogenic risk were the Castelli and proatherogenic indices based on the TC/cHDL ratio. Results: Predominantly in fertile age, with a mean of 27.3 years, in early preeclampsia the mean was 30.6 weeks and in late preeclampsia 37.6 weeks. In the pathological history, multiparity was found in 211 pregnant women, followed by chronic arterial hypertension in 207. Of the total 506 patients, 488 had moderate and maximum risk (419 (82.8%) maximum atherogenic risk and 69 (13.6%) moderate risk) with a marked predominance in the group of late onset preeclampsia. Conclusions: They generally belong to the reproductive age group, most are multiparous, and chronic arterial hypertension is one of the most frequent antecedents found. Maximum and moderate atherogenic risk predominated in most of the women with aggravated preeclampsia, especially in late onset. (provided by Infomedic International)

RESUMEN

Introducción: El crecimiento y el desarrollo son fenómenos biológicos que implican aumento de masa celular y diferenciación de forma o función, respectivamente. En beneficio del diagnóstico, se utilizan las bondades del ultrasonido en la evolución biométrica del crecimiento fetal. Objetivo: Determinar mensuraciones biométricas fetales más asociadas a la restricción del crecimiento fetal en infantes que sufrieron restricción del crecimiento intrauterino. Métodos: Se realizó un estudio longitudinal descriptivo y retrospectivo de gestantes captadas en dos áreas de salud del municipio Santa Clara, que terminaron su embarazo entre septiembre del 2013 y octubre del 2018 y cuyos recién nacidos experimentaron restricción del crecimiento. La muestra se clasificó al nacimiento en pequeños y adecuados, según condición trófica y en cada grupo se estudió relación con valores percentilares de variables biométricas en los dos últimos trimestres. Resultados: Predominaron en todas las biometrías y en los dos trimestres los valores por debajo del décimo percentil. En la totalidad de los infantes y durante todo el período fetal, la circunferencia abdominal estuvo por debajo del percentil 10. En las variables largo del fémur y circunferencia cefálica los percentiles más altos se encontraron en el tercer trimestre y desde el segundo en la variable diámetro biparietal, posiblemente relacionado con restricciones asimétricas del crecimiento. Conclusiones: La variable biométrica circunferencia abdominal desde el segundo trimestre es fiable en la detección de restricciones del crecimiento intrauterino y su existencia por debajo del décimo percentil debe servir como certeza de su existencia, aun cuando la condición trófica del recién nacido parezca revelar otra realidad(AU)


Introduction: Growth and development are biological phenomenons involving cell mass increase and differentiation of form or function, respectively. For diagnostic purposes, the benefits of ultrasound are used for the biometric evolution of fetal growth. Objective: To determine fetal biometric measurements mostly associated with fetal growth restriction in infants who suffered intrauterine growth restriction. Methods: A descriptive and retrospective longitudinal study was carried out with pregnant women from two health areas of Santa Clara Municipality, who finished their pregnancy between September 2013 and October 2018 and whose newborns experienced growth restriction. The sample was classified at birth into small and adequate, according to trophic condition; and, in each group, the relationship with percentile values of biometric variables in the last two trimesters was studied. Results: Values below the tenth percentile predominated in all biometrics and in the two trimesters. In all infants and during the whole fetal period, abdominal circumference was below the tenth percentile. In the variables femur length and cephalic circumference, the highest percentiles were found in the third trimester; while, from the second trimester on, the same occurred in the variable biparietal diameter, possibly related to asymmetric growth restrictions. Conclusions: The biometric variable abdominal circumference is, from the second trimester on, reliable in the detection of intrauterine growth restrictions; its existence below the tenth percentile should serve as certainty of its existence, even when the trophic condition of the newborn seems to reveal another reality(AU)

RESUMEN

This cross-sectional study aimed to develop and validate a patient-reported outcomes (PROs) assessment tool to assess symptom burden and daily functioning in patients after chimeric antigen receptor (CAR) T-cell therapy, the MD Anderson Symptom Inventory (MDASI-CAR). The items were generated based on literature review, content elicitation interviews with patients, and clinician's review. The patients completed the MDASI core and module, single-item quality-of-life (QoL) measure and Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29). The psychometric validation analysis was based on the acceptability after item reduction process. The final 10 MDASI-CAR module items included tremors, fever/chills, headache, balance, dizziness, attention, difficulty speaking, coughing, sexual dysfunction, and diarrhoea with high internal consistency (Cronbach's alpha: MDASI Core, 0.865; MDASI Interference, 0.915; CAR-T module, 0.746). The MDASI-CAR has excellent known-group validity that was demonstrated by differentiate patients based on patient's performance status (Cohen's d for MDASI core = -1.008, interference = -0.771, module = -0.835). Criterion validity was demonstrated by the significant correlations between the MDASI-CAR composite score, the single QoL item and the relevant domains on PROMIS-29 (all p < 0.05). This study established the MDASI-CAR module as a reliable and valid PRO tool for monitoring symptom burden after CAR T-cell therapy in patients with haematological malignancies. The findings need to be validated with a longitudinal design.

RESUMEN

Traditionally, underrepresented racial and ethnic groups experience marginalization, leading to inequities and disparities in health and health care. A holistic approach to care delivery can help providers meet a culturally diverse patient population's unique healing needs. A systematic assessment of nurses' cultural competency practice was conducted in Pennsylvania to reveal opportunities and provide direction for holistic, culturally competent health care services. This exploratory cross-sectional descriptive study used the Cultural Competence Education and Awareness Survey (CCEAS) to examine cultural competence practices of registered nurses employed in the state of Pennsylvania. A total of 1246 registered nurses completed the survey. Respondents expressed a strong desire for cultural competency. Education and organizational infrastructure to facilitate cultural competency could be improved. Health care leaders and policy makers at all levels should explore opportunities to strengthen nurses' culturally competent practices through ongoing professional-development activities and enhanced organizational infrastructure.

RESUMEN

Introducción: El equipo de rehabilitación asume un papel importante en el manejo de secuelas que pueden derivarse de la COVID-19 por el virus SARS-CoV-2. Objetivo: Caracterizar a pacientes que han padecido la COVID-19 y relacionar las pautas terapéuticas en rehabilitación con variables de interés. Métodos: Se realizó un estudio descriptivo en el Policlínico Universitario Santa Clara, de enero a septiembre del año 2021. En la totalidad de pacientes 322 con diagnóstico confirmado de COVID-19, por la prueba de reacción en cadena de la polimerasa en tiempo real con examen negativo al egreso. Se estudiaron las variables: edad, sexo, comorbilidades, síntomas y presencia de complicaciones en el curso de la enfermedad, síntomas post COVID-19, pautas rehabilitadoras. Se mostraron distribuciones de frecuencias absolutas y relativas. En el análisis estadístico se utilizó la prueba de independencia basada en la distribución chi cuadrado. Se tuvo en cuenta consideraciones éticas. Resultados: Prevaleció el sexo masculino y el grupo de edad entre 18 a 59 años; la comorbilidad más frecuente fue la hipertensión arterial. En el curso de la enfermedad fue la tos el síntoma más frecuente y en la valoración post COVID-19 la debilidad muscular. Un porcentaje elevado de casos necesitó rehabilitación, ya sea domiciliaria o institucional. La necesidad de rehabilitación domiciliaria o institucional alcanzó mayor frecuencia ante la presencia de comorbilidades y complicaciones. Conclusiones: Las comorbilidades y complicaciones mostraron una relación estadísticamente significativa con las pautas terapéuticas.


Introduction: The rehabilitation team assumes an important role in the management of sequelae that may result from COVID-19 due to the SARS-CoV-2 virus. Objectives: To characterize patients who have suffered from COVID-19 and relate therapeutic guidelines in rehabilitation with variables of interest. Methods: A descriptive study at the Santa Clara University Polyclinic, from January to September 2021. In all patients (322) with a confirmed diagnosis for SARS-CoV-2, by the polymerase chain reaction test in time real with negative exam at discharge. The variables were studied: age, sex, comorbidities, symptoms and presence of complications in the course of the disease, post-COVID-19 symptoms, rehabilitation guidelines. Absolute and relative frequency distributions were shown. In the statistical analysis, the test of independence based on the chi-square distribution was used. Ethical considerations were taken into account. Results: The male sex and the age group between 18 to 59 years prevailed; the most frequent comorbidity was high blood pressure. During the course of the disease, cough was the most frequent symptom and in the post-COVID-19 assessment, muscle weakness. A high percentage of cases required rehabilitation, either home or institutional. The need for home or institutional rehabilitation was more frequent in the presence of comorbidities and complications. Conclusions: Comorbidities and complications showed a statistically significant relationship with therapeutic guidelines.

RESUMEN

Introducción: Las acumulaciones excesivas de tejido adiposo, general o regional, constituyen hallazgos de valor clínico en el seguimiento nutricional y cardiometabólico durante la gestación y en el período posparto. Objetivo: Describir los cambios en la adiposidad corporal trascurridos 18 meses después del parto. Método: Se realizó un estudio observacional descriptivo de la adiposidad corporal, entre enero 2017 y agosto 2018, en 119 mujeres en el posparto a corto plazo, cuya adiposidad corporal se había estudiado al momento de la captación en el policlínico "Chiqui Gómez Lubián". Resultados: En el posparto con respecto al momento de la captación, se observó una disminución de las mujeres sin adiposidad general de 28,6 % a 21,8 % y de las mujeres con adiposidad general intermedia de 62,2 % a 53,8 %; con un aumento marcado de aquellas con adiposidad general alta de 9,2 % a 24,4 %. Aumentó la cantidad de mujeres con adiposidad central alta de 35,3 % a 43,7 % y disminuyeron las mujeres sin adiposidad central de 64,7 % a 56,3 %. Conclusiones: Evaluar los cambios de la adiposidad corporal por técnicas antropométricas sencillas y de fácil acceso, durante el embarazo y en el posparto a corto plazo, puede ofrecer información de utilidad para una mejor orientación del seguimiento de la salud cardiometabólica de la mujer.


Introduction: Excessive accumulations of adipose tissue, whether general or regional, are findings of clinical value in nutritional and cardiometabolic follow-up during pregnancy and in the postpartum period. Objective: To describe the changes in body adiposity at eighteenth months after delivery. Methods: A descriptive and observational study of body adiposity was carried from January 2017 to August 2018 in 119 women in the short-term postpartum period, whose body adiposity had been studied during the first antenatal visit at "Chiqui Gómez Lubián" Polyclinic. Results: In the postpartum period, with respect to the first antenatal visit, a decrease was observed in the number of women without general adiposity (from 28.6 % to 21.8 %) and of women with intermediate general adiposity (from 62.2 % to 53.8 %), with a marked increase in the number of women with high general adiposity (from 9.2 % to 24.4 %). The number of women with high central adiposity increased (from 35.3 % to 43.7 %), while the number of women without central adiposity decreased (from 64.7 % to 56.3 %). Conclusions: To evaluate the changes in body adiposity by simple and easily accessible anthropometric techniques, during pregnancy and in the short-term postpartum period, may provide useful information for designing better the follow-up of cardiometabolic health of women.
