Introducción: La infección por Listeria monocytogenes es una enfermedad grave que afecta mayoritariamente a personas de edad avanzada e inmunodeprimidos y cuya incidencia está aumentando. En este estudio se analizan los casos de listeriosis en dos hospitales con el fin de estudiar cambios en su incidencia, formas de presentación clínica y posibles factores asociados a mortalidad. Material y métodos: Estudio retrospectivo multicéntrico de pacientes con listeriosis diagnosticada por aislamiento microbiológico entre 1977 y 2021 en dos hospitales universitarios de Madrid. Se recogen variables epidemiológicas, clínicas, estado de inmunodepresión, pruebas complementarias y tratamiento. Se analizan factores asociados a mortalidad. Resultados: Se analizaron 194 casos de listeriosis. La incidencia de listeriosis por ingresos aumentó a lo largo del estudio, con una importante caída del número de casos en 2020. La bacteriemia aislada (37,1%) y la afectación del sistema nervioso central (SNC) (36,6%) fueron las presentaciones más frecuentes. El 21% de los casos tuvo síntomas de gastroenteritis. El 16,5% presentó otras infecciones focales, siendo las más frecuentes peritonitis bacteriana espontánea (8,2%), colecistitis (2,1%), infección respiratoria (1,5%) e infección de prótesis vascular (1,5%). La mortalidad intrahospitalaria fue del 24,7%. Fueron factores independientes asociados a mortalidad al ingreso la edad (odds ratio [OR] 1.027, intervalo de confianza [IC] 95% 1.003-1.056) y la presencia de tumor sólido (OR 3.525, IC 95% 1.652-7.524). Conclusiones: En este estudio se constata un aumento de la incidencia de listeriosis en nuestro medio. Las presentaciones más frecuentes fueron la bacteriemia aislada y la afectación del SNC. La mortalidad intrahospitalaria se asoció a la edad y al diagnóstico de tumor sólido.(AU)

Introduction: Listeria monocytogenes infection is a severe disease affecting mainly aged people and patients with immune depression. The incidence of listeriosis seems to be increasing. In the present study cases of listeriosis from two hospitals are analyzed with the aims of studying changes in its incidence, clinical forms of presentation and possible factors associated with mortality. Methods: Retrospective multicentric study of patients with culture-proven listeriosis in two university hospitals in Madrid between 1977 and 2021. Epidemiological and clinical variables, as well as factors for immune depression, complementary studies and treatments were registered. Factors associated with mortality were analyzed. Results: A total of 194 cases of listeriosis were analyzed. The incidence of listeriosis among in-patients increased through the study period, with a significant drop in the number of cases in 2020. The most common clinical presentations were isolated bacteriemia (37.1%) and central nervous system involvement (CNS) (36.6%). Symptoms of gastroenteritis occurred in 21% of cases. Other focal infections were present in 16.5% of patients, the most frequent were spontaneous bacterial peritonitis (8.2%), cholecystitis (2.1%), respiratory infection (1.5%) and vascular prothesis infection (1.5%). In-hospital mortality was 24.7%. Independent factors associated with mortality at admission were age (odds ratio [OR] 1.027, 95% confidence interval [95% CI]1.003–1.056) and a diagnosis of a solid tumor (OR 3.525, 95% CI1.652–7.524). Conclusions: This study confirms an increasing incidence of listeriosis in our millieu. The most common clinical presentations were isolated bacteriemia and central nervous system involvement. In-hospital mortality was associated with age and the diagnosis of a solid tumor.(AU)

An Undergraduate Interprofessional Experience with Self-Learning Methodology in Simulation Environment (MAES©): A Qualitative Study.

This article describes the impact that a Self-learning Methodology in Simulated Environments can have on Interprofessional Education within a Crisis Resource Management simulated scenario. We used a qualitative approach. It is divided into three phases: study and design, plan of action, and analysis and evaluation. During the first phase of the study, there emerged a poor use of Interprofessional Education in the nursing and medical degrees, and it became apparent that there was a need for an implementation. Due to the possibility for better training for both technical and non-technical skills within Crisis Resource Management, a simulation scenario within this setting has been established as a learning baseline objective. The technique used to develop the scenario in the second phase of the study was the Self-learning Methodology in Simulated Environments. Its structure, comprising six items, was previously demonstrated in the literature as appropriate for healthcare degree students. The main result of the third phase shows an overall acceptance of an Interprofessional Education within Self-learning Methodology in Simulated Environments during the practice of a Crisis Resource Management scenario. The integrated application of a Self-learning Methodology in Simulated Environments, Interprofessional Education, and Crisis Resource Management result in a synergistic combination that allows students to share knowledge, technical, and non-technical skills using an innovative learning method.

High First Trimester Levels of TSH as an Independent Risk Factor for Gestational Diabetes Mellitus: A Retrospective Cohort Study.

Although numerous articles have found an association between alterations in thyroid function and the risk of gestational diabetes mellitus (GDM), other studies have failed to demonstrate this association. This may be due to the different cut-off points used to define subclinical hypothyroidism. We aim to clarify the role of thyroid stimulating hormone (TSH) level in GDM within pregnant women with normal free thyroxine (fT4) levels. This retrospective cohort study was performed in 6775 pregnant women. The association between TSH and GDM was assessed by bivariate and multivariate logistic regression. Pregnant women with subclinical hypothyroidism are at significantly greater risk for GDM when compared with euthyroid pregnant women (OR = 1.85; 95% CI = 1.36-2.52). We have also observed that TSH levels increase the risk of GDM within euthyroid pregnant women, since the TSH levels between 2.5 and 4.71 showed a higher risk of GDM than those whose TSH levels are between 0.31 and 2.49 (OR = 1.54; 95% CI = 1.28-1.84). In addition, pregnant women with positive thyroid antibodies have almost 2.5 times the risk of developing GDM (OR = 2.47; 95% CI = 1.57-3.89). Our results support that in pregnant women with normal fT4 levels, higher first trimester TSH level implies a higher risk of GDM.

INTERGROWTH-21st versus a customized method for the prediction of neonatal nutritional status in hypertensive disorders of pregnancy.

BACKGROUND: Hypertensive disorders of pregnancy (HDP) generate complications and are one of the principal causes of maternal, foetal, and neonatal mortality worldwide. It has been observed that in pregnancies with HDP, the incidence of foetuses small for their gestational age (SGA) is twice as high as that in noncomplicated pregnancies. In women with HDP, the identification of foetuses (SGA) is substantially important, as management and follow-up are determined by this information. OBJECTIVE: The objective of this study was to evaluate whether the INTERGROWTH-21st method or customized birthweight references better identify newborns with an abnormal nutritional status resulting from HDP. METHOD: A comparative analysis study was designed with two diagnostic methods for the prediction of neonatal nutritional status in pregnancies with HDP. The performance of both methods in identifying neonatal malnutrition (defined by a neonatal body mass index < 10th centile or a ponderal index < 10th centile) was assessed by calculating sensitivity, specificity, positive predictive value, negative predictive value, diagnostic odds ratio, Youden's index and probability ratios. RESULTS: The study included 226 pregnant women diagnosed with HDP. The customized method identified 45 foetuses as small for gestational age (19.9%), while the INTERGROWTH-21st method identified 27 newborns with SGA (11.9%). The difference between proportions was statistically significant (p < 0.01). Using body mass index (< 10th centile) as a measure of nutritional status, newborns identified as SGA by the customized method showed a higher risk of malnutrition than those identified as SGA by INTERGROWTH-21st (RR: 4.87 (95% CI: 1.86-12.77) vs. 3.75 (95% CI: 1.49-9.43)) (DOR: 5.56 (95% CI: 1.82-16.98) vs. 4.84 (95% CI: 1.51-15.54)) Even when using Ponderal index (< 10th centile), newborns identified as SGA by the customized method showed a higher risk of malnutrition than those identified as SGA by INTERGROWTH-21st (RR 2.37 (95% CI: 1.11-5.05) vs. 1.68 (95% CI: 0.70-4.03))(DOR 2.62 (95% CI: 1.00-6.87) vs. 1.90 (95% CI: 0.61-5.92)). CONCLUSION: In pregnant women with HDP, the predictive ability of the customized foetal growth curves to identify neonatal malnutrition appears to surpass that of INTERGROWTH-21st.

Nursing Diagnosis of Grieving in Cases of Perinatal Loss: A Preliminary Clinical Validation.

PURPOSE: To develop a preliminary clinical validation the NANDA-I nursing diagnosis "Grieving" in cases of perinatal loss. METHODS: Descriptive cross-sectional study using the Fehring model. FINDINGS: The overall clinical validity index for the diagnosis was 0.15. Only four defining characteristics and five manifestations identified in the literature were validated. CONCLUSIONS: The variability of manifestations identified in the study participants is considered to be detrimental to the overall clinical validity index. IMPLICATIONS FOR NURSING PRACTICE: The clinical validity of the diagnosis could not be substantiated by the preliminary results of this study and, therefore, additional research is necessary to determine the ability of the diagnosis to adapt to perinatal loss situations in real contexts. Some manifestations have been proposed to NANDA-I for inclusion as defining characteristics in the nursing diagnosis of grieving. OBJETIVO: Validar clínicamente de forma preliminar el diagnóstico enfermero NANDA-I duelo en caso de pérdida perinatal. MÉTODOS: Estudio descriptivo transversal usando el modelo de Fehring. RESULTADOS: El índice de validez clínica global del diagnóstico fue de 0.15. Se validaron únicamente cuatro características definitorias y cinco manifestaciones identificadas en la literatura. CONCLUSIONES: Se considera que la variabilidad de las manifestaciones presentadas por los participantes actuó en detrimento del índice de validación clínica global. IMPLICACIONES PARA LA PRÁCTICA ENFERMERA: La validez clínica del diagnóstico no pudo ser corroborada por los resultados preliminares de este estudio y, por tanto, se necesita investigación adicional para terminar la capacidad de este diagnóstico para adaptarse a las situaciones de pérdidas perinatales en contexto reales. Se han propuesto a NANDA-I algunas manifestaciones para que sean incluidas como Características Definitorias del diagnóstico enfermero Duelo.

Design of a nursing objective structured clinical examination of a first-year clinical practice program.

OBJECTIVE: The aim of the present study was to design a content-valid nursing objective structured clinical examination attending a first-year clinical nursing practice program. METHOD: The examination was designed following a procedure based on the consensus of experts which was comprised of three phases: selection of the activities in which students should be competent according to the learning outcomes of the course, clinical case design, and integration of the clinical cases designed into the stations of the test. RESULTS: Of the 44 surveys submitted for the design of the stations, 37 were answered, of which 31 respondents met the inclusion criteria of the panel of experts. The activities on which the experts reached the highest degrees of consensus were: basic physical assessment and monitoring of vital signs, assessment of hygiene and skin status, ability to develop care plans, management of safety principles in administration of medication and administration of oral medication. Based on the selected activities, the experts developed 20 clinical cases, from which a four-station nursing objective structured clinical examination was designed. CONCLUSION: The structured methodology based on the design of experts enabled the design of a content-valid objective structured clinical examination appropriate for the evaluation of the learning outcomes achieved by the students attending a clinical practice program.

"INTERGROWTH21st vs customized fetal growth curves in the assessment of the neonatal nutritional status: a retrospective cohort study of gestational diabetes".

BACKGROUND: Gestational diabetes mellitus is associated with increased incidence of adverse perinatal outcomes including newborns large for gestational age, macrosomia, preeclampsia, polyhydramnios, stillbirth, and neonatal morbidity. Thus, fetal growth should be monitored by ultrasound to assess for fetal overnutrition, and thereby, its clinical consequence, macrosomia. However, it is not clear which reference curve to use to define the limits of normality. Our aim is to determine which method, INTERGROWTH21st or customized curves, better identifies the nutritional status of newborns of diabetic mothers. METHODS: This retrospective cohort study compared the risk of malnutrition in SGA newborns and the risk of overnutrition in LGA newborns using INTERGROWTH21st and customized birth weight references in gestational diabetes. The nutritional status of newborns was assessed using the ponderal index. Additionally, to determine the ability of both methods in the identification of neonatal malnutrition and overnutrition, we calculate sensitivity, specificity, positive predictive value, negative predictive value and likelihood ratios. RESULTS: Two hundred thirty-one pregnant women with GDM were included in the study. The rate of SGA indentified by INTERGROWTH21st was 4.7% vs 10.7% identified by the customized curves. The rate of LGA identified by INTERGROWTH21st was 25.6% vs 13.2% identified by the customized method. Newborns identified as SGA by the customized method showed a higher risk of malnutrition than those identified as SGA by INTERGROWTH21st. (RR 4.24 vs 2.5). LGA newborns according to the customized method also showed a higher risk of overnutrition than those classified as LGA according to INTERGROWTH21st. (RR 5.26 vs 3.57). In addition, the positive predictive value of the customized method was superior to that of INTERGROWTH21st in the identification of malnutrition (32% vs 27.27%), severe malnutrition (22.73% vs 20%), overnutrition (51.61% vs 32.20%) and severe overnutrition (28.57% vs 14.89%). CONCLUSIONS: In pregnant women with DMG, the ability of customized fetal growth curves to identify newborns with alterations in nutritional status appears to exceed that of INTERGROWTH21st.

Nurses' characteristics and practice environments: Comparison between clusters with different attitude and utilisation profiles regarding nursing diagnosis.

AIM: To identify clusters of nurses in relation to the utilisation and attitude towards nursing diagnosis and to compare their profiles considering demographics, professional characteristics and nursing practice environments. BACKGROUND: Nursing diagnosis has benefits for both patients and nurses, and the attitude of nurses towards nursing diagnosis has been proposed as a determinant of its use. Therefore, an adequate understanding of nurses' attitude and utilisation profiles regarding nursing diagnosis is essential for the nursing managers who want to adopt nursing diagnosis as a practice framework. METHODS: A cross-sectional survey design was used. A sample of 239 nurses working in the Catalan primary health care system were categorised into clusters with similar attitude and utilisation profiles, which were compared with each other a posteriori. RESULTS: Nursing managers were grouped into more positive attitude clusters than clinical nurses. Nurses working in supportive nursing practice environments were classified into more positive attitude and higher utilisation clusters. CONCLUSION: The field of work and nursing practice environments were found as differential factors in profiles of nurses with different attitudes towards and/or utilisation of nursing diagnosis. IMPLICATIONS FOR NURSING MANAGEMENT: The promotion of supportive nursing practice environments could enhance the implementation and maintenance of nursing diagnosis as a practice framework in primary health care.

[Overweight and obesity at risk factors for hypertensive states of pregnancy: a retrospective cohort study]. / Sobrepeso y obesidad como factores de riesgo de los estados hipertensivos del embarazo: estudio de cohortes retrospectivo.

INTRODUCTION: obesity has been associated with an increased risk of preeclampsia and gestational hypertension. OBJECTIVE: to determine if overweight and/or maternal obesity at the beginning of the pregnancy are associated with an increased risk of suffering from some hypertensive state of pregnancy in a population of southern Spain. METHODS: retrospective cohort study. We studied 4,711 cases where the IMC had been registered at the beginning of pregnancy. Two study groups were included: overweight/obesity at the beginning of the gestation. CONTROL GROUP: pregnant women with normal BMI at the beginning of gestation. Global risk of hypertensive disorders of pregnancy (HDP) and the risk of gestational hypertension, preeclampsia, chronic hypertension and preeclampsia superimposed on chronic hypertension were evaluated. RESULTS: maternal overweight was associated with an increased risk of HDP (OR 2.04, 95% CI: 1.43-2.91) and an increased risk of gestational hypertension (OR 1.68, 95% CI: 1.03-2.72) and chronic HT (OR: 3.70, 95% CI: 1.67-8.18). Maternal obesity was associated with an increase in some HDP (OR 3.54, 95% CI: 2.65-4.73), gestational hypertension (OR 2.94, 95% CI: 2-4.33), chronic HT (OR 8.31, 95% CI: 4.23-16.42) and preeclampsia (OR 2.08, 95% CI: 1.12-3.87) In the multivariate analysis (adjusted for parity and maternal age), overweight was associated with an increased risk of gestational hypertension (OR: 1.74, 95% CI: 1.06-2.85), chronic HT (OR 3.76, 95% CI: 1.69-8.35) and preeclampsia (OR 2.12, 95% CI: 1.005-4.48); obesity also increased the risk of gestational hypertension (OR 2.40, 95% CI: 1.39-4.13), chronic hypertension (OR 17.96, 95% CI: 8.78-36.76) and preeclampsia (OR 3, 69; 95% CI: 1.64-8.27). CONCLUSIONS: in conclusion, a significant and independent association was found between maternal overweight/obesity and HDP. The risk is significantly higher as the BMI increases (from overweight to obesity grade 3).

Se estudiaron 4.711 casos en los cuales se había registrado el IMC al inicio de la gestación. Grupos de estudio: a) sobrepeso; y b) obesidad al inicio de la gestación (desglosada por tipo de obesidad). Grupo control: IMC normal al inicio de la gestación. Se calculó el riesgo de presentar estados hipertensivos del embarazo (EHE) en general, hipertensión arterial (HTA) gestacional, preeclampsia, HTA crónica y preeclampsia sobreañadida a HTA crónica.Resultados: el sobrepeso materno se asoció a un incremento del riesgo de padecer algún EHE (OR 2,04, IC 95%: 1,43-2,91) y a un incremento del riesgo de padecer HTA gestacional (OR 1,68, IC 95%: 1,03-2,72) e HTA crónica (OR: 3,70, IC 95%: 1,67-8,18). La obesidad materna se asoció a un incremento de padecer algún EHE (OR 3,54, IC 95% 2,65-4,73), HTA gestacional (OR 2,94, IC 95% 2-4,33), HTA crónica (OR 8,31, IC 95%: 4,23-16,42) y preeclampsia (OR 2,08, IC 95%: 1,12-3,87). En el análisis multivariante (ajustado por la paridad y edad materna), el sobrepeso se asoció a un riesgo aumentado de padecer HTA gestacional (OR:1,74, IC 95%: 1,06-2,85), HTA crónica (OR 3,76, IC 95% 1,69-8,35) y preeclampsia (OR 2,12, IC 95% 1,005-4,48); la obesidad también incrementó el riesgo de HTA gestacional (OR 2,40, IC 95% 1,39-4,13), HTA crónica (OR 17,96, IC 95% 8,78-36,76) y preeclampsia (OR 3,69, IC 95% 1,64-8,27). Conclusiones: el sobrepeso y la obesidad aumentan el riesgo de padecer EHE. El riesgo es significativamente mayor conforme se incrementa el IMC (desde sobrepeso a obesidad grado 3).

Olive Oil Consumption and Bone Microarchitecture in Spanish Women.

Olive oil has been demonstrated to enhance various cardiometabolic risk factors. However, to our knowledge, the association between olive oil intake and cortical and trabecular bone microarchitecture has never been evaluated in Spanish women. We aimed to examine the association between olive oil intake and cortical and trabecular bone microarchitecture. We analyzed 523 women aged 50 (9) year, range (23⁻81) year. Participants underwent dual-energy X-ray absorptiometry and peripheral quantitative computed tomography scans. Dietary intake of calcium, vitamin D, energy and olive oil (g/day) were assessed by a self-administered food frequency questionnaire (FFQ). After adjustment for potential confounding factors (calcium (mg/day), vitamin D (µg/day) energy (Kcal/day), age, body mass index (BMI) (kg/m²), menopausal status, and osteoporotic diagnosis (normal, osteopenia, or osteoporosis)), there were significant increases in volumetric bone mineral density (vBMD) (mg/cm³) (p < 0.01) in the group with a higher intake of olive oil. Total, trabecular and cortical bone density were positively correlated with olive oil intake. The dietary intake of olive oil was significantly associated with vBMD in multiple regression analysis; total density: olive oil intake (g/day) standardized ß = 0.185 (p < 0.001), trabecular density: olive oil intake (g/day) standardized ß = 0.186 (p < 0.001) and cortical density olive oil intake (g/day) standardized ß = 0.114 (p = 0.008). We conclude that the dietary intake of olive oil is positively associated with a better vBMD in Spanish women.

A Student Assessment Tool for Standardized Patient Simulations (SAT-SPS): Psychometric analysis.

BACKGROUND: The evaluation of the level of clinical competence acquired by the student is a complex process that must meet various requirements to ensure its quality. The psychometric analysis of the data collected by the assessment tools used is a fundamental aspect to guarantee the student's competence level. AIM: To conduct a psychometric analysis of an instrument which assesses clinical competence in nursing students at simulation stations with standardized patients in OSCE-format tests. METHOD: The construct of clinical competence was operationalized as a set of observable and measurable behaviors, measured by the newly-created Student Assessment Tool for Standardized Patient Simulations (SAT-SPS), which was comprised of 27 items. The categories assigned to the items were 'incorrect or not performed' (0), 'acceptable' (1), and 'correct' (2). PARTICIPANTS: 499 nursing students. Data were collected by two independent observers during the assessment of the students' performance at a four-station OSCE with standardized patients. Descriptive statistics were used to summarize the variables. The difficulty levels and floor and ceiling effects were determined for each item. Reliability was analyzed using internal consistency and inter-observer reliability. The validity analysis was performed considering face validity, content and construct validity (through exploratory factor analysis), and criterion validity. RESULTS: Internal reliability and inter-observer reliability were higher than 0.80. The construct validity analysis suggested a three-factor model accounting for 37.1% of the variance. These three factors were named 'Nursing process', 'Communication skills', and 'Safe practice'. A significant correlation was found between the scores obtained and the students' grades in general, as well as with the grades obtained in subjects with clinical content. CONCLUSIONS: The assessment tool has proven to be sufficiently reliable and valid for the assessment of the clinical competence of nursing students using standardized patients. This tool has three main components: the nursing process, communication skills, and safety management.

Indications of caesarean section in overweight and obese versus normal-weight pregnant women: a retrospective cohort study.

PURPOSE: The aim of this study was to test the hypothesis that indications of c-section in overweight or obese pregnant women are different from those with normal-weight. METHODS: Retrospective cohort study at University Hospital of Puerto Real (Cádiz-Spain). We compared frequency distribution of c-section indications in overweight and obese versus normal-weight. The risk of c-section by different indications was calculated as relative risk. RESULTS: A total of 4685 births were included in the study. There are significant differences in the frequency distribution of caesarean indications among normal weight and overweight or obese women. In overweight, we found an increased risk of c-section due to previous c-section (RR: 1.73; confidence interval [CI] 95% 1.24-2.42), obstructed/non-progressive labour (RR: 1.34; CI 95% 1.03-1.75), failed induction of labour (RR: 2.38; CI 95% 1.30-4.34) and foetal distress (RR: 1.73; CI 95% 1.21-2.49). This risk was even higher in obese women: previous c-section (RR: 3.25; CI 95% 2.24-4.71), obstructed/non-progressive labour (RR: 2; CI 95% 1.45-2.77), failed induction (RR: 2.52; CI 95% 1.15-5.51) and foetal distress (RR: 2.35; CI 95% 1.51-3.65). CONCLUSIONS: The risk of caesarean section due to previous caesarean section, obstructed/non-progressive labour, failed induction of labour or foetal distress is greater in overweight and obese than in normal-weight. This increase in risk also increases progressively as maternal BMI increases.

"Hypothyroidism screening during first trimester of pregnancy".

BACKGROUND: Subclinical hypothyroidism is defined as an elevated thyroid-stimulating hormone level with a normal thyroxin level without signs or symptoms of hypothyroidism. Although it is well accepted that overt hypothyroidism has a deleterious impact on pregnancy, recent studies indicate that subclinical hypothyroidism may affect maternal and fetal health. Studies suggest an association between miscarriage and preterm delivery in euthyroid women positive for anti-peroxidase antibodies and/or anti-thyroglobulin antibodies. A proposal of a new set-point to diagnose SCH was recently published. The aim of this research was to determine the optimal thyroid-stimulating hormone cut-off point to screen for subclinical hypothyroidism in the first trimester of gestation in a population of our clinical area and to determine the diagnostic value of this screening test for detecting anti-thyroid peroxidase antibodies. METHODS: This cross-sectional study determines the cutoff point for SCH screening and evaluates its usefulness to detect TPO Ab using the Receiver Operating Characteristics (ROC) curve. Prevalence of SCH was calculated using as cut-off 2.5 mIU/L, 4 mIU/L, and our TSH 97.5th percentile. The ability to detect positive anti-thyroglobulin antibodies (TG Ab) and anti-thyroid peroxidase antibodies (TPO Ab) in patients with levels of TSH >97.5th percentile was determined by ROC curves. RESULTS: The mean, range and standard deviation of TSH was 2.15 ± 1.34 mIU/L (range 0.03-8.82); FT4 was 1.18 ± 0.13 ng/dL (range 0.94-1.3); TG Ab was 89.87 ± 413.56 IU/mL (range 0.10-4000); and TPO Ab was 21.61 ± 46.27 IU/mL(range 0.10-412.4). The ROC. analysis of the ability of the TSH level to predict the presence of positive TPO Ab found an AUC of 0.563. CONCLUSION: In our population, the TSH cutoff value for gestational SCH screening is 4.7 mIU/L. Using the SEGO recommended 2.5 mIU/L TSH cut-off point, the prevalence of SCH is 37%. Applying the ATA 2017 recommended cutoff point of 4 mIU/L, the prevalence of SCH is 9.6%. Finally, when the cut-off of 4.7 mIU/L (our 97.5th centile) was used, the SCH prevalence is 5%. TSH levels in the first trimester of pregnancy are not useful to detect TPO Ab.

Maternal underweight and perinatal outcomes: a restrospective cohort study / Infrapeso materno y resultados perinatales: estudio de cohortes retrospectivo.

Introduction: Some studies have linked maternal underweight with adverse perinatal outcomes such as spontaneous abortion, abruptio placentae, small for gestational age newborn, intrauterine growth retardation and preterm birth. Objective: To determine the influence of maternal underweight in the onset of labor, route of delivery, birth weight, Apgar score and preterm birth. Methods: Retrospective cohort study. We included pregnant women from the Hospital Universitario de Puerto Real. Period of study: 2002-2011. Study group: underweight at the beginning of gestation (BMI < 18.5 kg/m2). Control group: pregnant women with normal body mass index (BMI) at the beginning of gestation (18.5-24.9 kg/m2). The risk (OR) of induction of labor, cesarean section, small for gestational age newborn, macrosomia, 5' Apgar score < 7, and preterm birth was calculated. Results: The prevalence of underweight was 2.5% versus 58.9% of pregnant women who had a normal BMI. We found no significant differences in the rate of induction of labor, fetal macrosomia, Apgar at 5' < 7 or preterm delivery. Maternal underweight was associated with a decreased risk of caesarean section (adjusted OR 0.45, 95% CI 0.22 to 0.89) and an increased risk of small for gestational age newborn (adjusted OR 1.74; 95% CI 1.05 to 2.90). Conclusions: Maternal underweight at the start of pregnancy is associated with a lower risk of caesarean section and a greater risk of small for gestational age newborns (birth weight < P10).

Introducción: algunos estudios han asociado el infrapeso materno con resultados perinatales adversos tales como aborto espontáneo, desprendimiento placentario, feto pequeño para edad gestacional, crecimiento intrauterino retardado y parto pretérmino. Objetivos: determinar si el infrapeso materno al inicio de la gestación influye sobre la forma de inicio y vía del parto, peso al nacer, índice de Apgar al minuto 5 y edad gestacional en el momento del parto. Métodos: estudio de cohortes retrospectivo en gestantes adscritas al Hospital Universitario de Puerto Real. Periodo de estudio: 2002-2011. Grupo de estudio: infrapeso al inicio de la gestación (índice de masa corporal [IMC] < 18,5); grupo control: IMC normal al inicio de la gestación (18,5-24,9). Analizamos el riesgo (OR) de inducción de parto, cesárea, bajo peso al nacer, macrosomía, Apgar a los 5' < 7 y parto pretérmino. Resultados: la prevalencia de infrapeso fue del 2,5% frente al 58,9% de gestantes que presentaron un IMC normal. No encontramos diferencias significativas en la tasa de inducción de parto, macrosomía fetal, Apgar a los 5' < 7 ni parto pretérmino. El infrapeso materno se asoció a una disminución en el riesgo de cesárea (OR ajustada 0,45; IC 95% 0,22-0,89) y a un riesgo aumentado de presentar recién nacido pequeño para su edad gestacional (OR ajustada 1,74; IC 95% 1,05-2,90). Conclusiones: el infrapeso materno al inicio de la gestación se asocia a una menor probabilidad de que el parto finalice mediante la realización de una cesárea y a un mayor riesgo de que el recién nacido presente un peso al nacer por debajo del percentil 10.

Development and Psychometric Evaluation of a Questionnaire Based on the Nursing Outcomes Classification to Determine the Knowledge of Parents on Breast-Feeding: Research Protocol.

PURPOSE: To develop and psychometrically evaluate a questionnaire based on the outcome "Knowledge: Breast-feeding" of the Nursing Outcomes Classification (NOC) to determine the knowledge of parents on breast-feeding. BACKGROUND: The NOC outcome "Knowledge: Breast-feeding" allows for nurses/midwives to assess the efficacy of interventions aimed to improve the knowledge on breast-feeding in parents thought the clinical interview/observation. However, the use of self-administered questionnaires by patients could facilitate its evaluation. METHODS: Two-phased study: (1) Development of the questionnaire based on experts' opinions; (2) Methodological design to assess its psychometric properties. IMPLICATIONS FOR NURSING PRACTICE: The availability of tools that enable the determination of the knowledge of patients would facilitate nurses/midwives to set objectives, individualize interventions, and measure their effectiveness.
