RESUMEN
OBJECTIVES: Well-established clinical practice for assessing progress in labor involves routine abdominal palpation and vaginal examination (VE). However, VE is subjective, poorly reproducible and painful for most women. In this study, our aim was to evaluate the feasibility of systematically integrating transabdominal and transperineal ultrasound assessment of fetal position, parasagittal angle of progression (psAOP), head-perineum distance (HPD) and sonographic cervical dilatation (SCD) to monitor the progress of labor in women undergoing induction of labor (IOL). We also aimed to determine if ultrasound can reduce women's pain during such examinations. METHODS: Women were recruited as they presented for IOL in three maternity units. Ultrasound assessments were performed in 100 women between 37 + 0 and 41 + 6 weeks' gestation. A baseline combined transabdominal and transperineal scan was performed, including assessment of fetal biometry, umbilical artery and fetal middle cerebral artery Doppler, amniotic fluid index, fetal spine and occiput positions, psAOP, HPD, SCD and cervical length. Intrapartum scans were performed instead of VE, unless there was a clinical indication to perform a VE, according to protocol. Participants were asked to indicate their level of pain by verbally giving a pain score between 0 and 10 (with 0 representing no pain) during assessment. Repeated measures data were analyzed using mixed-effect models to identify significant factors that affected the relationship between psAOP, HPD, SCD and mode of delivery. RESULTS: A total of 100 women were included in the study. Of these, 20% delivered by Cesarean section, 65% vaginally and 15% by instrumental delivery. There were no adverse fetal or maternal outcomes. A total of 223 intrapartum ultrasound scans were performed in 87 participants (13 women delivered before intrapartum ultrasound was performed), with a median of two scans per participant (interquartile range (IQR), 1-3). Of these, 76 women underwent a total of 151 VEs with a median of one VE per participant (IQR, 0-2), with no significant difference between vaginal- or Cesarean-delivery groups. After excluding those with epidural anesthesia during examination, the median pain score for intrapartum scans was 0 (IQR, 0-1) and for VE it was 3 (IQR, 0-6). Cesarean delivery was significantly associated with a slower rate of change in psAOP, HPD and SCD. CONCLUSIONS: Comprehensive transabdominal and transperineal ultrasound assessment can be used to assess progress in labor and can reduce the level of pain experienced during examination. Ultrasound assessment may be able to replace some transabdominal and vaginal examinations during labor. © 2024 The Authors.

OBJECTIVE: To compare the predictive performance of three different mathematical models for first-trimester screening of pre-eclampsia (PE), which combine maternal risk factors with mean arterial pressure (MAP), uterine artery pulsatility index (UtA-PI) and serum placental growth factor (PlGF), and two risk-scoring systems. METHODS: This was a prospective cohort study performed in eight fetal medicine units in five different regions of Spain between September 2017 and December 2019. All pregnant women with singleton pregnancy and a non-malformed live fetus attending their routine ultrasound examination at 11 + 0 to 13 + 6 weeks' gestation were invited to participate in the study. Maternal characteristics and medical history were recorded and measurements of MAP, UtA-PI, serum PlGF and pregnancy-associated plasma protein-A (PAPP-A) were converted into multiples of the median (MoM). Risks for term PE, preterm PE (< 37 weeks' gestation) and early PE (< 34 weeks' gestation) were calculated according to the FMF competing-risks model, the Crovetto et al. logistic regression model and the Serra et al. Gaussian model. PE classification was also performed based on the recommendations of the National Institute for Health and Care Excellence (NICE) and the American College of Obstetricians and Gynecologists (ACOG). We estimated detection rates (DR) with their 95% CIs at a fixed 10% screen-positive rate (SPR), as well as the area under the receiver-operating-characteristics curve (AUC) for preterm PE, early PE and all PE for the three mathematical models. For the scoring systems, we calculated DR and SPR. Risk calibration was also assessed. RESULTS: The study population comprised 10 110 singleton pregnancies, including 32 (0.3%) that developed early PE, 72 (0.7%) that developed preterm PE and 230 (2.3%) with any PE. At a fixed 10% SPR, the FMF, Crovetto et al. and Serra et al. models detected 82.7% (95% CI, 69.6-95.8%), 73.8% (95% CI, 58.7-88.9%) and 79.8% (95% CI, 66.1-93.5%) of early PE; 72.7% (95% CI, 62.9-82.6%), 69.2% (95% CI, 58.8-79.6%) and 74.1% (95% CI, 64.2-83.9%) of preterm PE; and 55.1% (95% CI, 48.8-61.4%), 47.1% (95% CI, 40.6-53.5%) and 53.9% (95% CI, 47.4-60.4%) of all PE, respectively. The best correlation between predicted and observed cases was achieved by the FMF model, with an AUC of 0.911 (95% CI, 0.879-0.943), a slope of 0.983 (95% CI, 0.846-1.120) and an intercept of 0.154 (95% CI, -0.091 to 0.397). The NICE criteria identified 46.7% (95% CI, 35.3-58.0%) of preterm PE at 11% SPR and ACOG criteria identified 65.9% (95% CI, 55.4-76.4%) of preterm PE at 33.8% SPR. CONCLUSIONS: The best performance of screening for preterm PE is achieved by mathematical models that combine maternal factors with MAP, UtA-PI and PlGF, as compared to risk-scoring systems such as those of NICE and ACOG. While all three algorithms show similar results in terms of overall prediction, the FMF model showed the best performance at an individual level. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

Antecedentes Se ha descrito una elevada incidencia de tromboembolismo pulmonar (TEP) durante la pandemia por coronavirus. Métodos Estudio retrospectivo unicéntrico, con revisión de las angiografías pulmonares por tomografía computarizada solicitadas por sospecha de tromboembolismo pulmonar durante dos períodos, del 01 de marzo del 2020 al 31de mayo del 2020 (pandemia), e igual intervalo en 2019 (control). Resultados Se diagnosticaron 22 tromboembolismos pulmonares durante el período control y 99 en el pandémico, 74 asociados con COVID-19. El 5,3% de los pacientes hospitalizados con COVID-19 sufrió un tromboembolismo pulmonar, con un retraso entre ambos diagnósticos de 9,1 ± 8,4 días. Durante la pandemia, los pacientes con tromboembolismo pulmonar tenían menos condiciones predisponentes (tromboembolismo pulmonar previo 5,1 vs. 18,2%, p = 0,05, cirugía previa 2 vs. 35,4%, p = 0,0001, trombosis venosa profunda 11,1 vs. 45,5%, p = 0,0001), y los tromboembolismos pulmonares periféricos eran más frecuentes (73,5 vs. 50%, p = 0,029). Conclusiones Existe un riesgo incrementado de sufrir un TEP durante la pandemia por SARS-CoV-2, que afecta a pacientes con perfil clínico diferente y causa más frecuentemente TEP distales (AU)
Background A high incidence of pulmonary embolism has been described during the coronavirus pandemic. Methods This work is a single-center retrospective study which reviewed computed tomography pulmonary angiograms ordered due to suspected pulmonary embolism during two periods: from March 1, 2020 to May 31, 2020 (pandemic) and during the same interval in 2019 (control). Results Twenty-two pulmonary embolism were diagnosed during the control period and 99 in the pandemic, 74 of which were associated with COVID-19. Of all patients hospitalized with COVID-19, 5.3% had a pulmonary embolism, with a delay between the two diagnoses of 9.1 ± 8.4 days. During the pandemic, patients with pulmonary embolism had fewer predisposing conditions (previous pulmonary embolism 5.1 vs. 18.2%, p = .05; previous surgery 2 vs. 35.4%, p = .0001; deep vein thrombosis 11.1 vs. 45.5%, p = .0001); peripheral pulmonary embolisms were the most frequent (73.5 vs. 50%, p = . 029). Conclusions There is an increased risk of having a pulmonary embolism during the SARS-CoV-2 pandemic, which affects patients with a different clinical profile and more often causes distal pulmonary embolisms (AU)

Introducción: Actualmente no existe ningún tratamiento curativo para la demencia por lo que se considera que su prevención es clave. El objetivo es analizar la asociación entre los factores de riesgo y la demencia, y su variación según la edad y el sexo. Pacientes y métodos: Este estudio transversal incluye a 1.048.956 personas de 65 años o más. Los datos se obtuvieron de la base de datos clínicos pseudoanonimizados SIDIAP. La variable respuesta fue la demencia y se identificaron los casos mediante un algoritmo validado. Se evaluó la exposición a los siguientes factores de riesgo: tabaquismo, enfermedad coronaria, enfermedad cerebrovascular, insuficiencia cardíaca, arteriopatía periférica, alcoholismo, hipertensión arterial, hiperlipidemia, diabetes, hipertiroidismo, Parkinson, trastorno depresivo y ruralidad. Se calcularon modelos de regresión logística para evaluar la asociación de los factores de riesgo y la demencia, y se estratificó por edad, sexo y ambos conjuntamente. Resultados: La asociación entre los antecedentes de enfermedad cerebrovascular, el Parkinson, el trastorno depresivo o el hipertiroidismo y la demencia fue más pronunciada en los hombres. La asociación inversa entre la enfermedad coronaria, la insuficiencia cardíaca o el tabaquismo con la demencia fue significativa sólo en las mujeres. Se observó una mayor asociación en los grupos de menor edad en la mayoría de los factores de riesgo. Conclusión: El sexo y la edad condicionan la asociación de los factores de riesgo y la demencia. Recomendamos promover el control eficaz de los factores de riesgo cardiovascular para prevenir la demencia.(AU)
Introduction: There is currently no cure for dementia and its prevention is considered to be crucial. The aim is to analyse the association between risk factors and dementia, and how this varies according to age and sex. Patients and methods: This cross-sectional study includes 1,048,956 people aged 65 and over. Data were obtained from the SIDIAP pseudonymised clinical database. The response variable was dementia and cases were identified using a validated algorithm. Exposure to the following risk factors was assessed: smoking, coronary heart disease, cerebrovascular disease, heart failure, peripheral arterial disease, alcoholism, high blood pressure, hyperlipidaemia, diabetes, hyperthyroidism, Parkinsons disease, depressive disorder and rurality. Logistic regression models were estimated to assess the association between risk factors and dementia, and they were stratified by age, sex and both jointly. Results: The association between a medical history of cerebrovascular disease, Parkinson, depressive disorder or hyperthyroidism and dementia was more pronounced in men. The inverse association between coronary heart disease, heart failure or smoking and dementia was significant only in women. A stronger association was observed in younger age groups for most risk factors, but hypertension, coronary heart disease, heart failure or smoking were negatively associated among the older age groups. Conclusion: Sex and age both condition the association between risk factors and dementia. We recommend promoting effective control of cardiovascular risk factors in order to prevent dementia.(AU)

Objetivo. Determinar el papel de la gammagrafía salival (GS) cuantitativa en la detección de alteraciones funcionales de las glándulas salivales en pacientes con cáncer de cabeza y cuello tratados con radioterapia (RT). Material y métodos. Se estudió a 19 pacientes (17 varones) con edad media de 62,4 años (4475). Se realizaron tres estudios a cada paciente: basal, a los 3 y a los 18 meses tras la RT. La gammagrafía salival se realizó con 3,7MBq/kg de 99mTc-pertecnetato durante 25 minutos y zumo de limón al final del minuto 15. Se calculó la fracción de excreción (FE), las cuentas máximas/minuto/píxel/MBq (CMPM), el porcentaje de captación a partir de las curvas actividad/tiempo de áreas de interés sobre ambas glándulas parótidas (GP) y glándulas submaxilares (GSM) y la influencia de las dosis recibidas por las parótidas. Resultados. La FE mostró una disminución significativa del estudio basal a los 3 meses (p<0,001), tanto en las GP como en las GSM, y a los 18 meses en las GSM (p<0,001). Se observó un aumento significativo de la FE del estudio a los 3 meses al de los 18 meses (p<0,05). Resultados. La CMPM no cambió significativamente en las GP desde el estudio basal a los de 3 y 18 meses, pero sí en las GSM con disminución significativa (p<0,01) desde el estudio basal al de 18 meses. El porcentaje de captación no cambió significativamente. Se observó correlación moderada entre la dosis a parótidas y los parámetros a los 3 meses post-RT (p<0,05). Conclusiones. La FE presentó mayor sensibilidad que la captación al efecto de la RT sobre la función salival, mostrando, además, recuperación funcional a lo largo del tiempo en las GP(AU)
Objective. To assess the role of quantitative salivary gland scintigraphy (SGS) in the detection of functional impairment of salivary glands in patients with head and neck cancer treated with radiotherapy (RT). Material and methods. We studied 19 patients (17 men), mean age 62.4 years (4475). Three studies were performed to each patient: baseline, 3 and 18 months after RT. SGS was acquired for 25 minutes following injection of 3.7MBq/kg of 99mTc-pertechnetate with lemon juice at the end of minute 15. Material and methods. Excretion fraction (EF), counts per minute/pixel/MBq (CMPM) and uptake percentage were obtained from time-activity curves from ROIs placed over parotid (PG) and submandibular glands (SMG) and related to the doses received by the PG. Results. EF showed a significant reduction from the baseline to the 3 months study (p<0.001) for the PG and SMG and from the baseline to the 18 months study for the SMG (p<0.001). A significant improvement of EF was seen from the 3 months to the 18 months study for the PG (p<0.05). Results. CMPM did not change significantly from the baseline to the 3 months and 18 months studies for the PG and showed a significant reduction (p<0.01) for the SMG from the baseline to 18 months study. The uptake percentage did not change significantly between studies. A moderate association was observed between the doses to PG and the 3m study parameters. Conclusions. EF was more sensitive than uptake in assessing post-RT impairment of salivary function. In addition, it reflected functional recovery of parotid glands over time(AU)

Entre el 1 y el 4 por ciento de los tumores germinales (TG) pueden originarse en el mediastino, siendo esta su localización extragonadal más frecuente. De ellos, los tumores germinales mediastínicos (TGM) no seminomatosos como el coriocarcinoma son menos habituales, más agresivos y de peor pronóstico. Presentamos el caso de un paciente varón de 34 años, diagnosticado de inicio en Febrero del 2000 de un coriocarcinoma mediastínico primario con metástasis pulmonares bilaterales, hepáticas y cerebrales, aprovechando la ocasión para revisar algunas características de estos tumores, de su historia natural, diagnóstico y tratamiento (AU)
