RESUMEN

INTRODUCTION: Peripheral trauma is a very frequent cause of consultation in paediatric emergency departments but few studies have been published describing the characteristics of these patients. MATERIAL AND METHODS: We performed a retrospective descriptive study by reviewing computerised emergency department forms during January and February 2020. OBJECTIVE: To describe the characteristics of traumatic injuries in our area and to detect possible areas for improvement. RESULTS: A total of 714 peripheral trauma cases were attended, which represents 9.5% of the total consultations. A total of 52.7% were schoolchildren (6-11 years). The most frequent locations were the ankle (27.5%) and fingers (17.2%). Fracture was detected in 6.7% of cases. Radiographs were requested in 78.6% of the patients, with pathological findings in 9.6% of them. Half of the X-rays were requested due to ankle or finger trauma. Referral to traumatology was made in 16.4% of patients, mainly for elbow and knee trauma, and the most commonly used treatment was general measures (49%) and bandaging (29.4%). CONCLUSIONS: Peripheral trauma is very common and, in general, banal. A large number of X-rays are requested with a very low yield, so it seems necessary to establish new protocols to reduce the number of requests. Improving training in elbow and knee trauma could improve paediatricians' autonomy in dealing with these more complex injuries.

RESUMEN

OBJECTIVES: Women with a hypertensive disorder of pregnancy (HDP) are at increased risk of developing hypertension and cardiovascular disease later in life. However, from previous studies, it is difficult to define whether this association reflects pre-existing maternal cardiovascular risk or a potentially causal relationship between HDP and later cardiovascular risk. In this study, we performed detailed cardiovascular assessment in women in midgestation, prior to development of HDP, and at 2 years postpartum, aiming to identify cardiovascular changes prior to development of HDP and to assess persistent cardiovascular alterations long after the HDP event. METHODS: This was a prospective observational study in which we performed detailed cardiovascular assessment in midgestation and at a median of 2.3 (interquartile range, 2.1-2.4) years postpartum. We examined 112 women who developed HDP and 451 women whose pregnancy was not complicated by hypertension. We used conventional and more advanced (i.e. speckle tracking) echocardiographic techniques to determine accurately left ventricular systolic and diastolic function. We used M-mode measurements to determine left ventricular remodeling and estimate left ventricular mass. Maternal vascular status was assessed using ophthalmic artery Doppler and by calculating peak systolic velocity (PSV) ratio, as a marker of peripheral vascular resistance. RESULTS: In midgestation, women who subsequently developed HDP had increased ophthalmic artery PSV ratio. These women also had mild cardiac functional and morphological alterations, which were accounted for mostly by maternal cardiovascular risk factors. At 2 years postpartum, women who had experienced HDP, compared to those who did not, had cardiovascular abnormalities with reduction in left ventricular systolic and diastolic function, which remained after multivariable analysis. Longitudinal analysis demonstrated that the evolution of cardiovascular changes in the HDP and non-HDP groups was similar. CONCLUSIONS: Mild cardiac functional and morphological alterations precede the development of HDP and such changes persist for at least 2 years postpartum. The cardiac changes are likely to be the consequence of pre-existing maternal cardiovascular risk factors rather than an adverse consequence of HDP. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

RESUMEN

OBJECTIVE: Epidemiological studies suggest that, following in-utero exposure to hypertensive disorder of pregnancy (HDP), children may be at increased long-term cardiovascular risk, but data in early childhood are lacking. We aimed to investigate the independent influence of HDP on infant cardiac structure and function, after accounting for differences in childhood risk-factor profile. METHODS: This was a longitudinal study of 71 children born of a pregnancy complicated by HDP (gestational hypertension or pre-eclampsia) and 304 children born of a normotensive pregnancy. Detailed cardiovascular assessment was performed at mid gestation and at a median of 2.3 (interquartile range, 2.1-2.4) years postnatally. Linear mixed-effects modeling was used to determine the independent influence of HDP on infant cardiac function and structure after accounting for differences in childhood risk-factor profile. RESULTS: There were no differences in demographic characteristics between children whose mother developed HDP and those born of a normotensive pregnancy, but delivery was earlier and birth weight was lower in the HDP group. In fetal life, there were no significant differences in cardiac function or structure between the HDP and non-HDP groups. In early childhood, in the HDP group compared with the non-HDP group, there was greater relative wall thickness (mean ± SD, 0.7 ± 0.3 vs 0.6 ± 0.3; P = 0.047) and increased left ventricular mass (indexed to body surface area) (mean ± SD, 80.9 ± 20.4 g/m2 vs 75.7 ± 16.5 g/m2; P = 0.024); however, these differences did not persist on multivariable analysis. Longitudinal analysis revealed that there was no difference in the change in cardiac functional indices from fetal life to early childhood between the HDP and non-HDP groups. CONCLUSION: There is no evidence that HDP has an adverse effect on offspring cardiovascular health in fetal life or in early childhood. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

RESUMEN

Photoinduced phase transitions in correlated materials promise diverse applications from ultrafast switches to optoelectronics. Resolving those transitions and possible metastable phases temporally are key enablers for these applications, but challenge existing experimental approaches. Extreme nonlinear optics can help probe phase changes, as higher-order nonlinearities have higher sensitivity and temporal resolution to band structure and lattice deformations. Here the ultrafast transition from the semiconducting to the metallic phases in polycrystalline thin-film NbO_{2} is investigated by time-resolved harmonic spectroscopy. The emission strength of all harmonic orders shows a steplike suppression when the excitation fluence exceeds a threshold (∼11-12 mJ/cm^{2}), below the fluence required for the thermal transition-a signature of the nonthermal emergence of a metallic phase within 100±20 fs. This observation is backed by full ab initio simulations as well as a 1D chain model of high-harmonic generation from both phases. Our results demonstrate femtosecond harmonic probing of phase transitions and nonthermal dynamics in solids.

RESUMEN

High-harmonic generation is typically thought of as a sub-laser-cycle process, with the electron's excursion in the continuum lasting a fraction of the optical cycle. However, it was recently suggested that long-lived Rydberg states can play a particularly important role in high harmonic generation by atoms driven by the combination of the counterrotating circularly polarized fundamental light field and its second harmonic. Here we report direct experimental evidence of very long and stable Rydberg trajectories contributing to high-harmonic generation in such fields. We track their dynamics inside the laser pulse using the spin-orbit evolution in the ionic core, utilizing the spin-orbit Larmor clock. We confirm their effect on harmonic emission both via microscopic simulations and by showing how this radiation can lead to a well-collimated macroscopic far-field signal. Our observations contrast sharply with the general view that long-lived Rydberg orbits should generate negligible contribution to the macroscopic far-field high harmonic response of the medium.

RESUMEN

BACKGROUND: To determine the number of nurses who are supervised by a charge nurse in the Nursing Units of Aragonese general public hospitals and to analyze how this affects the organizational behaviors of nurses and the quality of the relationships established with the charge nurses. METHODS: Cross-sectional study carried out in nine public hospitals. Validated questionnaires were used to assess the working behavior of nurses and the quality of their relationships with charge nurses, and the charge nurse's relationship with their immediate superior and nursing staff. We analyzed whether there was an association between these variables and the number of nurses per unit. RESULTS: The study included 2,541 nurses and 192 supervisors. The mean span of control was 29 (SD=22.4). Statistically significant differences were observed with respect to empowerment (p<0.001), satisfaction (p=0.027), perceived organizational support (p<0.001) and the quality of the nurse's relationships with the supervisor (p<0.001) and the supervisor with her immediate superior (p<0.001), obtaining lower scores as the span of control increased. No significant associations were observed with respect to turnover intention, organizational citizenship behavior and organizational commitment. CONCLUSIONS: The span of control is related to the perception of nurses' organizational behaviors and with the quality of interpersonal relationships with the charge nurse, indicating a need to adjust the span of of control per unit in order to improve the quality of the management of the units.

RESUMEN

OBJECTIVE: To define the sensitization pattern of patients with anaphylaxis to Vespa velutina nigrithorax (VVN). METHODS: We studied 100 consecutive Spanish patients with anaphylaxis to Hymenoptera venom and systematically determined specific IgE (sIgE) to whole venoms (Vespula species, Polistes dominula, Apis mellifera, Vespa crabro, and Dolichovespula maculata) and their molecular components (rApi m 1, rApi m 5, rApi m 10, rVes v 1, rVes v 5, rPol d 5, and cross-reactive carbohydrates). Specific IgE to VVN venom and its antigen 5 (nVesp v 5) were measured in a subsample. RESULTS: Seventy-seven patients had anaphylaxis to VVN. Of these, only 16 (20.8%) reported previous VVN stings, but were stung by other Hymenoptera. Positive sIgE (>0.35 kUA/L) to each of the whole venoms was detected in >70% of patients (Vespula species in 100%). The components showing >50% positivity were rApi m 5 (51.4%), rPol d 5 (80.0%), and rVes v 5 (98.7%). This pattern was similar to that of Vespula species anaphylaxis (n=11) but different from that of A mellifera anaphylaxis (n=10). Specific IgE to nVesp v 5 was positive in all patients (n=15) with VVN anaphylaxis and was correlated with sIgE to both rVes v 5 (R=0.931) and rPol d 5 (R=0.887). CONCLUSIONS: VVN has become the commonest cause of Hymenoptera anaphylaxis in our area. Most cases report no previous VVN stings. Their sensitization pattern is similar to that of patients with anaphylaxis to other Vespidae. Specific IgE to antigen-5 from VVN, Vespula species, and P dominula are strongly correlated in patients with VVN anaphylaxis.

RESUMEN

BACKGROUND: Mycoplasma bovis is an important pathogen for the cattle industry worldwide causing significant economic losses. Several transmission routes, including those related to reproduction, have been described. Indeed, the pathogen can colonize the female reproductive tract after artificial insemination (AI) with contaminated semen. Lactobacillus spp.-based probiotics have been used for vaginal dysbiosis treatment in women and cows although their role in controlling cervico-vaginal infections due to M. bovis is unknown. The objective of the present work is to assess the viability of M. bovis (PG45, NCTC 10131) in experimentally contaminated cervical mucus after the addition of Lactobacillus spp. at different concentrations as a competing agent and pH acidifier. RESULTS: The addition of probiotic at a concentration higher than 108 colony forming units (CFU/mL had a detrimental effect (P < 0.05) on mycoplasma viability in cervical mucus. This coincided with a significant LAB growth and an important decrease in pH from 8.4 to 5.6 (P < 0.05). However, after the addition of less concentrated probiotic, M. bovis survival was not affected and there was no significant LAB growth despite the drop of pH from 8.4 to 6.73 (P < 0.05). CONCLUSION: The addition of concentrations higher than 108 CFU/mL of Lactobacillus spp. negatively affects M. bovis viability in bovine cervical mucus under in vitro conditions. Although the effect observed on the pathogen viability seems to be related to the pH decrease after LAB proliferation in cervical mucus, further studies are necessary to elucidate if other factors are implicated. Nevertheless, the administration of Lactobacillus spp.-based probiotics might be used in the future to control M. bovis proliferation in the cervico-vaginal tract of cows.

RESUMEN

The use of cryopreserved dolphin spermatozoa facilitates the exchange of genetic material between aquatic parks and makes spermatozoa accessible to laboratories for studies to further our understanding of marine mammal reproduction. Sperm cryopreservation in the bottlenose dolphin (Tursiops truncatus) has been developed for the exchange of gametes within the ex situ population. The aim of this study was to develop an effective method for refrigeration of bottlenose dolphin spermatozoa diluted in a commercial extender (BTS). In Experiment 1, the effect of temperature (5 compared with 15 °C) on sperm quality was evaluated during 7 days of storage at 100 × 106 spermatozoa/ml. In Experiment 2, the effect of the storage concentration (100 × 106 compared with 20 × 106 spermatozoa/ml) on sperm quality was assessed during 7 days of storage at 5 °C. In Experiment 1, total motility (including % of rapid sperm) was greater at 5 than 15 °C. When the effect of storage concentration was evaluated (Experiment 2), total motility and ALH were greater at the higher storage concentration (100 × 106 spermatozoa/ml). For both experiments, values for viability, acrosome integrity, and normal morphology variables were consistent throughout the 7 days of refrigeration. In Experiment 3, a microbiological study was performed to evaluate the effect of the refrigeration temperature and days of storage on bacterial growth. The results of microbiological analysis indicated there was Staphylococcus aureus in some samples, however, there was no effect of temperature or days of refrigeration. In conclusion, bottlenose dolphin semen can be refrigerated for a short to medium period of storage and there is maintenance of functionality of sperm when stored at 100 × 106 spermatozoa/ml at 5 °C.

RESUMEN

AIM OF THE STUDY: The aim of this study is to identify potential perinatal risk or protective factors associated with NEC. MATERIALS AND METHODS: Single-center, retrospective case-control study of newborns admitted to the neonatal intensive care unit with NEC from 2014 to 2015. Clinical charts were reviewed recording maternal factors (fever, positive recto-vaginal swab and signs of corioamnionitis or fetal distress), and neonatal factors analyzed were: birth-weight and weeks gestation, umbilical vessel catheterization, time of enteral feedings and the use of probiotics, antibiotics and antifungal agents. Cases and controls were matched for all of these factors. Parametric tests were used for statistical analysis and p < 0.05 deemed significant. RESULTS: We analyzed 500 newborns of which 44 developed NEC (cases) and 456 controls. Univariate analysis did not identify any maternal risk factors for NEC. We did not found statistical differences between patients either time of enteral feedings or probiotics. Nevertheless, patients with signs of fetal distress and early sepsis had a higher risk of NEC (p < 0.0001). CONCLUSIONS: Infants with history of fetal distress and signs of early sepsis are at a higher risk of NEC. The use of prophylactic catheter infection or orotracheal intubation with antifungal treatment seemed to elevate the incidence of NEC. However, antibiotic treatment couldn´t be demonstrated to increase the risk of NEC.


OBJETIVOS: Identificar factores perinatales que favorezcan el desarrollo de enterocolitis necrotizante (ECN) en las unidades de cuidados intensivos neonatales (UCIN). METODOS: Estudio de casos y controles de los recién nacidos (RN) tratados entre 2014-2015. Se evaluaron factores de riesgo materno-fetal (fiebre, corioamnionitis, cultivos rectovaginales y sufrimiento intrauterino) y neonatales (edad gestacional, canalización de vasos umbilicales, hemocultivos, sepsis, nutrición y probióticos) y su asociación a la ECN. Estudiamos también la existencia de tratamiento antibiótico y antifúngico intravenoso previo al cuadro de ECN. Se estimó la odds ratio con un nivel de significación p < 0,05. RESULTADOS: Se analizaron 500 neonatos: 44 ECN y 456 controles. En el análisis univariante ninguno de los factores de riesgo maternos se relacionó con el desarrollo de ECN. No se encontraron diferencias significativas en los RN que recibieron alimentación enteral o probióticos. Los RN con sufrimiento fetal y los diagnosticados de sepsis precoz presentaron mayor riesgo de desarrollo de ECN (p < 0,0001). CONCLUSION: La pérdida de bienestar fetal y la sepsis precoz favorecen el desarrollo de ECN, que también parece aumentar con el uso de antibioterapia sistémica así como el tratamiento antifúngico profiláctico para las infecciones de catéter o intubaciones orotraqueales prolongadas.

RESUMEN

Several dental implants are commercially available and new prototype design are constantly being fabricated. Nevertheless, it is still unclear what parameters of the design affect most the osseointegration of dental implants. The purpose of this study is to assess the effects of the microscopic and macroscopic design of dental implants in the osseointegration by comparing three macroscopic designs (Straumann tissue level (STD), essential cone (ECD) and prototype design (PD)) and six surface treatments. A total of 96 implants were placed in 12 minipigs. The implant stability quotient (ISQ), was assessed at the time of implantation, as well as at 2, 4 and 8 weeks. Histomorphometric and statistical analyses were conducted at the different sacrifice times, being 2, 4 and 8 weeks, to analyse the bone to implant contact (BIC), the bone area density (BAT) and the density of bone outside the thread region (ROI). The macroscopic design results showed higher ISQ values for the ECD, whereas the histomorphometric analysis showed higher ossoeintegration values for the STD. Regarding the microscopic design, both Sandblasted plus acid etching (hydrochloric/sulphuric acid) in a nitrogen atmosphere (SLActive) and Shot-blasted or bombarded with alumina particles and posterior alkaline immersion and thermal treatment (ContacTi) showed superior results in terms of osseointegration and reduced the osseointegration times from 8 weeks to 4 weeks compared to the other analysed surfaces. In conclusion, each of the macroscopic and microscopic designs need to be taken into account when designing novel dental implants to enhance the osseointegration process.

RESUMEN

INTRODUCTION: Acquired stenosis of the airway is a common complication after endotracheal intubation. Endoscopic dilation has been accepted as the treatment of choice in cases detected precociously. Our goal is to know the current status of the patients treated in our hospital with endoscopic dilation in the last 10 years. MATERIAL AND METHODS: Retrospective cohort study of patients with subglottic and tracheal acquired stenosis (STAS) early treated endoscopically with balloon dilation at our center in the last 10 years. Bronchoscopy control at 2 weeks, a month, 3 and 6 months post-dilation were performed and later on depending on the symptoms. RESULTS: 32 patient were treated in the period considered. The median age was 4.5 (3-120) months. There were necessary 2.5 (1-5) dilations per patient. All cases were extubated in the operating room or in the following 24 hours. There were no complications during the procedure. Follow-up time was 6 (1-10) years. Only 1 of the 32 patients have had recurrence of stenosis 2 years after, it was secondary to reintubations due to new surgical interventions; which it was dilated successfully. CONCLUSIONS: Early endoscopic dilation in the acquired airway stenosis is a safe and effective long-term procedure. The results support the use of this technique as a treatment of choice in these patients.


INTRODUCCION: La estenosis adquirida de la vía aérea es una complicación frecuente tras la intubación endotraqueal. La dilatación endoscópica ha sido aceptada como tratamiento de elección en los casos detectados de forma precoz. Nuestro objetivo es conocer el estado actual de los pacientes tratados en nuestro centro mediante dilatación endoscópica en los últimos 10 años. MATERIAL Y METODOS: Estudio de cohorte retrospectivo de pacientes con estenosis subglóticas y traqueales adquiridas (ESTA) tratadas endoscópicamente mediante dilatación con balón en nuestro centro en los últimos 10 años. Se realizaron broncoscopias de control a las 2 semanas, al mes, a los 3 y 6 meses postdilatación y posteriormente en función de la clínica. RESULTADOS: Se trataron 32 pacientes de ESTA de reciente aparición en dicho periodo. La mediana de edad fue de 4,5 (3-120) meses. Fueron necesarias 2,5 (1-5) dilataciones por paciente. Todos los pacientes fueron extubados en quirófano o en las 24 horas siguientes al procedimiento. No hubo complicaciones durante los procedimientos ni durante el postoperatorio. El tiempo de seguimiento fue de 6 (1-10) años. Solo 1 de los 32 pacientes presentó recidiva de la estenosis 2 años después que fue secundaria a reintubaciones por nuevas intervenciones quirúrgicas; la cual se dilató nuevamente. CONCLUSIONES: La dilatación endoscópica precoz en las estenosis adquiridas de la vía aérea es un procedimiento seguro y eficaz a largo plazo. Los resultados avalan el uso de esta técnica como tratamiento de elección en estos pacientes.

RESUMEN

INTRODUCTION/AIM OF THE STUDY: Gastroschisis is a congenital malformation with an easy and early prenatal diagnosis, however, it has a variable post-natal outcome. Our aim was to determine if certain ultrasound markers or early delivery were related with a worse postnatal outcome. PATIENTS AND METHODS: Retrospective study of a cohort of patients with gastroschisis diagnosed between 2005-2014, with emphasis on prenatal ultrasounds, gestational age at delivery and post-natal outcome. Oligohydramnios, peel, mesenteric edema, fixed and dilated bowel with loss of peristalsis and small wall defect were considered ultrasonographic markers associated with poor prognosis. Outcome variables included: length-of-stay, complications, nutritional and respiratory factors. Non-parametric statistical analysis were used with p < 0,05 regarded as significant. RESULTS: Clinical charts of 30 patients with gastroschisis were reviewed (17M/13F). Gestational age at diagnosis was 20 (12-31) and at delivery 36 (31-39) weeks (33% of the patients over 36+3 weeks). A 73% of the patients presented at least one ultrasonographic marker factor during follow-up. Univariate analysis showed that mesenteric edema was associated with poor outcome variables: short-bowel syndrome (p= 0,000), PN-dependence (p= 0,007) and intestinal atresia (p= 0,02). The remaining risk factors analysed, including late delivery (> 36+3 weeks) were not associated with length-of-stay, ventilatory support, digestive autonomy, complications or mortality. CONCLUSIONS: Neither the presence of ultrasonographic markers classically associated with unfavorable outcomes, nor early delivery (< 36 weeks) resulted in worse postnatal outcome. Mesenteric edema was the only alarming ultrasound marker and that may suggest the need of closer follow-up.


INTRODUCCION: La gastrosquisis es una anomalía congénita de fácil diagnóstico prenatal y pronóstico postnatal variable. Nuestro objetivo es determinar si los signos ecográficos prenatales o el momento del parto se relacionan con peor pronóstico postnatal. PACIENTES Y METODOS: Se realiza un estudio retrospectivo de la cohorte de pacientes con gastrosquisis diagnosticados entre 2005-2014, registrando las ecografías prenatales, edad gestacional al parto y evolución postnatal. Se valoraron los hallazgos ecográficos prenatales: oligohidramnios, peel, edema mesentérico, asas fijas, aperistálticas y/o dilatadas y defecto pequeño de pared. Se consideraron variables resultado: la estancia hospitalaria, complicaciones, mortalidad y factores nutricionales y respiratorios. Se utilizaron pruebas no paramétricas, considerándose significativo un valor p < 0,05. RESULTADOS: Se analizaron 30 pacientes con gastrosquisis (17V/13M). La edad gestacional al diagnóstico fue de 20 (12-31) y al parto de 36 (31-39) semanas (33% mayores de 36+3 semanas). El 73% de los pacientes presentaron al menos un signo ecográfico de mal pronóstico. El análisis univariante asoció el edema mesentérico al síndrome de intestino corto (p= 0,000), falta de autonomía digestiva (p= 0,007) y mayor incidencia de atresia (p= 0,02). El resto de los factores, incluyendo la edad gestacional > 36+3 semanas, no tuvieron repercusión negativa en términos de estancia, asistencia respiratoria, autonomía digestiva, complicaciones o mortalidad. CONCLUSIONES: Ni la presencia de signos ecográficos considerados generalmente como desfavorables ni la tendencia a acercar el parto a la semana 36ª tienen repercusiones significativas en el curso postnatal. Únicamente el edema mesentérico parece un signo alarmante que sugiere la necesidad de aumentar la frecuencia de intervenciones (ecografías, pruebas de bienestar fetal).

RESUMEN

AIM OF THE STUDY: The hemodynamic imbalance due to placental vascular anastomoses in TTTS but also vascular changes generated after intrauterine treatment may lead to hypoxic-ischemic complications. Different intestinal complications in TTTS are reviewed in this paper. METHODS: Retrospective review of TTTS cases treated by laser coagulation (LC) from 2012-2015. Demographic data, fetal therapy, prenatal diagnosis (US, MRI) and perinatal outcome were recorded. We describe cases with intestinal complications and their postnatal management. Results are expressed by median and range. RESULTS: 29 monochorionic pregnancies with TTTS were treated (23 LC, 4 cord occlusions and 2 cord occlusions after LC). The diagnosis was made at 19 (16-26) weeks and 86% presented stage of Quintero ≥ II. In 70% of mothers survived at least one fetus with a median of 31 (24-37) weeks at birth. Four patients had intestinal complications (1 jejunal atresia, 2 ileal atresia, 1 perforated necrotizing enterocolitis), half of them had prenatal diagnosis. Postnatal resections of the affected segments and ostomies were performed. Intestinal transit was restored and there were no severe digestive sequelae after 21 (8-38) months of follow up. CONCLUSIONS: Different types of intestinal complications were associated with TTTS and LC. US and MRI enable prenatal diagnosis of these complications and this allows prompt decisions after birth.


INTRODUCCION: El desequilibrio hemodinámico secundario a la presencia de anastomosis vasculares placentarias en el STFF así como los cambios hemodinámicos generados durante y tras su tratamiento mediante fotocoagulación con láser (FC) puede dar lugar a complicaciones hipóxico-isquémicas en distintos sistemas. Revisamos nuestra experiencia en el tratamiento del STFF con FC y presentamos las complicaciones intestinales encontradas. MATERIAL Y METODOS: Estudio retrospectivo de casos tratados intraútero entre 2012 y 2015. Recogimos datos sociodemográficos, terapia fetal, pruebas diagnósticas prenatales (ecografía, RM) y resultados perinatales. Expresamos las medidas en medianas y rangos. RESULTADOS: Se procedió al tratamiento intraútero de 29 gestaciones monocoriales complicadas con STFF (23 FC, 4 oclusiones de cordón y 2 FC seguidas de oclusión). La edad gestacional en el procedimiento fue 19 (16-26) semanas y en el 86% de los casos se trataba de un estadio de Quintero ≥ II. El 70% de las madres tuvieron al menos 1 recién nacido vivo, con mediana de edad gestacional al parto de 31 (24-37) semanas. Presentaron problemas intestinales 4 pacientes (1 atresia yeyunal, 2 atresias ileales, 1 enterocolitis necrotizante con perforación), con sospecha prenatal diagnóstica en 2 de ellos. Postnatalmente se realizó resección del segmento afecto y ostomía. Actualmente se ha restablecido el tránsito intestinal en todos sin secuelas digestivas graves tras 21(8-38) meses de seguimiento. CONCLUSIONES: Hemos descrito distintos tipos de complicaciones intestinales asociadas al STFF y/o su tratamiento con FC. Es posible hacer el diagnóstico prenatal de dichas complicaciones mediante ecografía y RM. Su conocimiento pone al cirujano en alerta y es importante en la toma de decisiones postnatales.

RESUMEN

Objetivo: Identificar cuáles han sido las principales limitaciones y dificultades en el acceso a los recursos sociosanitarios que han vivido las personas al final de la vida, a través de las vivencias y las percepciones de los cuidadores de estos enfermos. Método: Estudio cualitativo multicéntrico con enfoque fenomenológico, mediante 5 grupos de discusión y 41 entrevistas en profundidad, en Andalucía, España. La selección de los participantes se realizó intencionadamente entre los cuidadores que habían sufrido la muerte de su familiar, entre 2 meses y 2 años después del fallecimiento. Se optó por el método de Giorgi para el análisis de la información, y como soporte informático utilizamos Atlas ti 6.0. Resultados: Se han obtenido una serie de categorías relacionadas con distintos niveles de asistencia sanitaria: el sufrimiento en los servicios de urgencias, la necesidad de intimidad, la sensación de soledad y la vivencia en el domicilio. Conclusiones: Los cuidadores han descrito una serie de obstáculos de acceso a los distintos recursos sociosanitarios, entre los que destacan la existencia de protocolos muy generales de atención que no tenían en cuenta el proceso de enfermedad de su familiar y la necesidad de una habitación individualizada, durante el ingreso hospitalario. En el domicilio se sienten protegidos por los profesionales de atención primaria, pero presentan dificultades de acceso a apoyo psicológico y a las unidades de cuidados paliativos. Por tanto, es prioritario que desde el sistema sanitario se puedan fomentar los aspectos asistenciales esenciales en la atención a estos enfermos y favorecer una muerte con dignidad.


Objective: From the perspective of their health providers, to identify the main limitations and difficulties which persons at the end of their lives have experienced in relation to their accessibility to social-sanitary resources. Method: This is a phenomenological-focused qualitative and multi-centric study which conducted 5 discussion groups and 41 in-depth interviews in Andalucia, Spain. The participant selection was limited to those health providers who had suffered the death of a family member within the past two years. The Giorgi method was chosen to analyze and back-up the data. Atlas ti 6.0 was also used. Results: From the analysis, several sanitary-assistance-level categories arose including: the suffering at the urgency services, the need of intimacy, the feelings of loneliness, and the life at home. Conclusions: The care providers described a series of barriers to the access to social-sanitary resources highlighting the very general attention protocols which did not integrally consider the illness process of the beloved, and the need to an individualized room while admission at the hospital. Although while at home, these persons feel protected under the attention of the primary care professionals, they have difficulties to having access to psychological support at the palliative care units. Therefore, it is a priority that, from the sanitary system, the essential assisting attention can be warranted, thus supporting these sick persons to go through death in dignity.
