Lung ultrasound and postoperative follow-up of congenital diaphragmatic hernia.

Lung ultrasound (LU) has emerged as a valuable tool for assessing pulmonary aeration noninvasively, rapidly, and reliably in different neonatal conditions. However, its role in the preoperative and postoperative evaluation in congenital diaphragmatic hernia (CDH) is still poorly analyzed. We present a cohort of 8 patients diagnosed with CDH who underwent lung ultrasound examinations at various time points before and after surgical correction. The lung ultrasound patterns were compared between two groups: mechanical ventilation ≤ 7 days (MV ≤ 7) and mechanical ventilation > 7 days (MV > 7). The ultrasound findings were also compared to CT scans and chest X-ray images to assess its diagnostic capacity for identifying postoperative complications: pneumothorax, pleural effusion, and pneumonia. Group MV ≤ 7 exhibited a normal pattern even at 48 h postsurgery, while group MV > 7 presented interstitial or alveolointerstitial pattern in both lungs for prolonged periods (2-3 weeks). Furthermore, contralateral LU pattern may be predictive of respiratory evolution.  Conclusion: Lung ultrasound is a valuable tool for evaluating the progressive reaeration of the lung following surgical correction in CDH patients. It demonstrates the ability to diagnose common postoperative complications without the need for radiation exposure while offering the advantages of quick and serial assessments. These findings highlight the potential of lung ultrasound as an effective alternative to conventional imaging methods in the management of CDH. What is Known: • Lung ultrasound evaluates lung aeration and predicts respiratory outcomes in neonatal patients. What is New: • Lung ultrasound is useful in the postsurgical management of congenital diaphragmatic hernia patients, detecting reaeration and respiratory complications.

[Statement of the Spanish Interdisciplinary Vascular Prevention Committee on the updated European Guidelines on Cardiovascular Disease Prevention]. / Comentario del CEIPV a las nuevas Guías Europeas de Prevención Cardiovascular 2021.

Statement of the Spanish Interdisciplinary Vascular Prevention Committee on the updated European Guidelines on Cardiovascular Disease Prevention. We present the Spanish adaptation of the 2021 European Guidelines on Cardiovascular Disease (CVD) prevention in clinical practice. The current guidelines besides the individual approach greatly emphasize on the importance of population level approaches to the prevention of cardiovascular diseases. Systematic global CVD risk assessment is recommended in individuals with any major vascular risk factor. Regarding LDL-Cholesterol, blood pressure, and glycemic control in patients with diabetes mellitus, goals and targets remain as recommended in previous guidelines. However, it is proposed a new, stepwise approach (Step 1 and 2) to treatment intensification as a tool to help physicians and patients pursue these targets in a way that fits patient profile. After Step 1, considering proceeding to the intensified goals of Step 2 is mandatory, and this intensification will be based on 10-year CVD risk, lifetime CVD risk and treatment benefit, comorbidities and patient preferences. The updated SCORE algorithm-SCORE2, SCORE-OP- is recommended in these guidelines, which estimates an individual's 10-year risk of fatal and non-fatal CVD events (myocardial infarction, stroke) in healthy men and women aged 40-89 years. Another new and important recommendation is the use of different categories of risk according different age groups (< 50, 50-69 ≥ 70 years). Different flow charts of CVD risk and risk factor treatment in apparently healthy persons, in patients with established atherosclerotic CVD, and in diabetic patients are recommended. Patients with chronic kidney disease are considered high risk or very high-risk patients according to the levels of glomerular filtration rate and albumin-to-creatinine ratio. New lifestyle recommendations adapted to the ones published by the Spanish Ministry of Health as well as recommendations focused on the management of lipids, blood pressure, diabetes and chronic renal failure are included.

Executive summary: Updates to the dietary treatment of prediabetes and type 2 diabetes mellitus.

Adequate lifestyle changes significantly reduce the cardiovascular risk factors associated with prediabetes and type 2 diabetes mellitus. Therefore, healthy eating habits, regular physical activity, abstaining from using tobacco, and good sleep hygiene are recommended for managing these conditions. There is solid evidence that diets that are plant-based; low in saturated fatty acids, cholesterol, and sodium; and high in fiber, potassium, and unsaturated fatty acids are beneficial and reduce the expression of cardiovascular risk factors in these subjects. In view of the foregoing, the Mediterranean diet, the DASH diet, a low-carbohydrate diet, and a vegan-vegetarian diet are of note. Additionally, the relationship between nutrition and these metabolic pathologies is fundamental in targeting efforts to prevent weight gain, reducing excess weight in the case of individuals with overweight or obesity; and personalizing treatment to promote patient empowerment. This document is the executive summary of an updated review that includes the main recommendations for improving dietary nutritional quality in people with prediabetes or type 2 diabetes mellitus. The full review is available on the webpages of the Spanish Society of Arteriosclerosis (SEA, for its initials in Spanish), the Spanish Diabetes Society (SED, for its initials in Spanish), and the Spanish Society of Internal Medicine (SEMI, for its initials in Spanish).

Resumen ejecutivo: actualización en el tratamiento dietético de la prediabetes y la diabetes mellitus tipo 2 / Executive summary: Updates to the dietary treatment of prediabetes and type 2 diabetes mellitus

Los cambios adecuados del estilo de vida reducen significativamente los factores de riesgo cardiovascular asociados a la prediabetes y la diabetes mellitus tipo 2, por lo que en su manejo se debe recomendar un patrón saludable de alimentación, actividad física regular, no consumir tabaco, y una buena higiene del sueño. Hay una sólida evidencia de que los patrones alimentarios de base vegetal, bajos en ácidos grasos saturados, colesterol y sodio, con un alto contenido en fibra, potasio y ácidos grasos insaturados, son beneficiosos y reducen la expresión de los factores de riesgo cardiovascular en estos sujetos. En este contexto destacan la dieta mediterránea, la dieta DASH, la dieta baja en hidratos de carbono y la dieta vegano-vegetariana. Adicionalmente, en la relación entre nutrición y estas enfermedades metabólicas es fundamental dirigir los esfuerzos a prevenir la ganancia de peso o a reducir su exceso en caso de sobrepeso u obesidad, y personalizar el tratamiento para favorecer el empoderamiento del paciente.Este documento es un resumen ejecutivo de una revisión actualizada que incluye las principales recomendaciones para mejorar la calidad nutricional de la alimentación en las personas con prediabetes o diabetes mellitus tipo 2, disponible en las páginas web de la Sociedad Española de Arteriosclerosis, la Sociedad Española de Diabetes y la Sociedad Española de Medicina Interna.(AU)

Ensayo clínico fase III para evaluar la eficacia y seguridad del uso de plasma rico en plaquetas frente a ácido hialurónico en coxartrosis / Randomized, double-blind, controlled trial, phase III, to evaluate the use of platelet-rich plasma versus hyaluronic acid in hip coxarthrosis

OBJETIVOS: Comparar la eficacia y seguridad de la infiltración de plasma rico en plaquetas preparado respecto a ácido hialurónico en pacientes con coxartrosis refractaria a tratamiento conservador. Así como correlacionar el impacto clínico entre las diferentes concentraciones celulares. MATERIALES Y MÉTODOS: Ensayo clínico fase III, doble-ciego, controlado, en el que se aleatorizaron a los pacientes en dos grupos de tratamiento (PRP o AH) con una única infiltración de cadera ecoguiada. El seguimiento fue de 12 meses, registrando escala de dolor (EVA) y escalas funcionales (HHS y WOMAC), analgesia consumida, respondedores (criterios OARSI) y efectos adversos. Se analizaron, en el grupo experimental, las concentraciones celulares en sangre periférica y en el PRP infiltrado. RESULTADOS: Se incluyeron un total de 74 pacientes. Ambos grupos de tratamiento presentaron mejoría en las escalas EVA, WOMAC, HHS y reducción del consumo de analgesia en el tiempo (p < 0,05). Únicamente encontramos diferencias significativas entre grupos al año de tratamiento en los valores de HHS (Grupo PRP 70,9 [3,7-58] grupo AH 60,2[43-74,2] p < 0,05). No se registraton efectos adversos en ninguno de los grupos. Encontramos correlación entre la concentración de plaquetas en pacientes respondedores (un mes postratamiento; no respondedores 449[438-578] x103 plaquetas/μl, respondedores 565 [481-666] x103 plaquetas/μl, p < 0,044). Se correlaciona la concentración de leucocitos con las escalas clínico-funcionales (EVA 6 meses, r=0,748, p < 0,013, subescala rigidez WOMAC 6 meses, r=0,748, p < 0,013). Los pacientes con estadios de coxartrosis iniciales (KL 1 y 2) tienen mayor probabilidad de responder al tratamiento con plasma rico en plaquetas (11,51 OR, IC 95% 2,34-50,65, p < 0,03). CONCLUSIONES: La infiltración única de PRP es eficaz en términos de mejoría funcional, reducción del dolor y disminución del consumo de analgesia en coxartrosis. Los sistemas de preparación abiertos, son un procedimiento seguro para la obtención de PRP. Se deben indicar las infiltraciones de cadera en estadios evolutivos iniciales. Se debe tener en cuenta la composición celular para garantizar una repuesta clínica positiva

AIMS OF THE STUDY: To compare efficacy and safety of a home-made platelet-rich plasma (PRP) solution versus hyaluronic acid in patients with hip osteoarthritis not responding to conservative treatment and to correlate cellular composition of PRP to clinical outcomes. MATERIAL AND METHODS: This is a phase III clinical trial, double-blinded, controlled and randomised into two treatment groups (PRP and hyaluronic acid). Patients received one hip ultrasound-guided injection. Follow up was 12 months. Pain was assessed using VAS score, HHS and WOMAC were used as functional scores, analgesia, adverse events, cellular components (PRP group) in peripheral blood and in PRP were recorded. Clinical response was assessed using OARSI criteria. RESULTS: Seventy-four patients were included. Both groups improved in VAS, WOMAC and HHS score and reduced the amount of analgesia (p<.05). Significant differences were seen at 1 year post-treatment in HHS score (PRP 70.9 [3.7-58], hyaluronic acid 60.2[43-74.2] p<.05). No adverse events were observed in none of the groups. Platelet concentration was different between responders and non-responders (at 1 month, non-responders 449[438-578] x103 platelets/μl versus responders 565 [481-666] x103 platelets/μl, p<.044). There was a correlation between leukocytes concentration and clinical scores (VAS at six months, r=0.748, p<.013, WOMAC at 6 months r=0.748, p <.013). Patients with early stage hip OA showed higher response rate to PRP compared with late stage (11.51 OR, 95%CI 2.34-50.65, p<.03). CONCLUSIONS: Platelet-rich plasma injection improved hip function, reduced pain and the use of analgesia. It is important to bear in mind the cellular composition in order to achieve a better clinical response

Buccal dental-microwear and feeding ecology of Early Pleistocene Theropithecus oswaldi from Cueva Victoria (Spain).

Despite the scarcity of fossil specimens of Theropithecus oswaldi in Eurasia, its presence out of Africa attests to the great dispersal of this Papionini genus during the Early Pleistocene. In the present study, we analyze the buccal dental microwear of T. oswaldi (T. o. leakeyi) fossil specimens from Cueva Victoria (Southeastern Spain). This analysis is the first characterization of the feeding ecology of T. oswaldi in Europe. The buccal microwear pattern of the molar and premolar teeth of T. oswaldi from Cueva Victoria shows great similarities to that observed for the extant frugivorous forest-dwelling Mandrillus sphinx and mangabeys (Cercocebus sp.)-both species adapted to durophagous dietary habits-while significantly different from that observed for the gramnivorous Theropithecus gelada. These results suggest that T. oswaldi from Cueva Victoria could have exploited both hard-shelled fruits or seeds and succulent fruits from open and forested Mediterranean ecosystems.

Características de los neonatos trasladados al hospital de referencia regional en Asturias / Characteristics of the newborns transferred to the regional reference hospital in Asturias

INTRODUCCIÓN: La regionalización de la asistencia neonatal es un punto importante de la asistencia pediátrica de calidad. Los traslados interhospitalarios neonatales forman parte de esta regionalización. OBJETIVO: Analizar las características de los neonatos trasladados al hospital de referencia en Asturias. MATERIAL Y MÉTODOS: Estudio observacional retrospectivo y descriptivo de los pacientes neonatales trasladados al Servicio de Neonatología del hospital regional de referencia, entre enero de 2017 y diciembre de 2018 en Asturias. RESULTADOS: Se incluyeron 136 pacientes (56 mujeres y 80 varones), lo que supone un traslado cada 5 días, el 1,8% de los neonatos nacidos en los hospitales emisores y el 14,4% de los ingresos en el hospital receptor. El 63,2% ingresaron en la unidad de cuidados intensivos y el 36,7% en la sala de cuidados intermedios, con un tiempo de ingreso medio de 9,5 días. El 20,7% eran prematuros. El peso medio al nacimiento fue de 2.983 g. La edad media al traslado fue de 5 días y el 46,3% de los traslados se realizaron durante las primeras 24 horas de vida. Las causas más frecuentes de traslado fueron: respiratorias (25%), neurológicas (14,7%), digestivas (13,2%) e infecciosas (12,5%). El 38% de los pacientes precisó soporte ventilatorio y el 1,4% falleció durante el ingreso. CONCLUSIONES: Los traslados neonatales interhospitalarios son relativamente frecuentes en nuestra región, siendo el distrés respiratorio y los problemas neurológicos las causas más comunes. El análisis de la regionalización de la asistencia neonatal resulta especialmente importante en regiones con escasa natalidad debido a la crisis demográfica

INTRODUCTION: Regionalization of neonatal care is an important point of quality in pediatric care. Neonatal interhospital transfers between regional hospitals and referral centers are part of this regionalization. OBJECTIVE: To analyze characteristics of newborns transferred from the different regional and private hospitals to theregional reference hospital in Asturias during 2017 and 2018. MATERIALS AND METHODS: An observational, descriptive and retrospective study was conducted, including all neonatal patients transferred fron other Asturian hospital to Neonatology Service of HUCA between January 2017 and December 2018, in Asturias. RESULTS: 136 patients were included (56 female and 80 male), which represents a transfer every 5 days, 1.8% of the 7,563 neonates born in the sending hospitals and 14.4% of the neonatal admissions in the receiving hospital. 63.2% of patients were admitted to the neonatal Intensive Care Unit and 36.7% to the neonatal Intermiediate care room with a mean admission time of 9.5 days. 20.7% were preterm newborns. The average born weight was 2,983 g. 20.6% were less than 2,500 g. Average age at transfer was 5 days, being the 46.3% made during first 24 hours of life. The most frequent causes of transfer were: respiratory (25%) neurological (14.7%), digestive (13.2%) and infectous (12.5%). 38% required ventilatory support and 1,4% died during admission. CONCLUSIONS: Neonatal inter-hospital transfers are relatively frequent in our region, with respiratory distress and neurological problems being the most common causes. The analysis of neonatal care regionalization is especially important in regions with low birth rates due to demographic crisis

Structural and molecular study of the supraspinatus muscle of modern humans (Homo sapiens) and common chimpanzees (Pan troglodytes).

OBJECTIVES: To analyze the muscle architecture and the expression pattern of the myosin heavy chain (MyHC) isoforms in the supraspinatus of Pan troglodytes and Homo sapiens in order to identify differences related to their different types of locomotion. MATERIALS AND METHODS: We have analyzed nine supraspinatus muscles of Pan troglodytes and ten of Homo sapiens. For each sample, we have recorded the muscle fascicle length (MFL), the pennation angle, and the physiological cross-sectional area (PCSA). In the same samples, by real-time quantitative polymerase chain reaction, we have assessed the percentages of expression of the MyHC-I, MyHC-IIa, and MyHC-IIx isoforms. RESULTS: The mean MFL of the supraspinatus was longer (p = 0.001) and the PCSA was lower (p < 0.001) in Homo sapiens than in Pan troglodytes. Although the percentage of expression of MyHC-IIa was lower in Homo sapiens than in Pan troglodytes (p = 0.035), the combination of MyHC-IIa and MyHC-IIx was expressed at a similar percentage in the two species. DISCUSSION: The longer MFL in the human supraspinatus is associated with a faster contractile velocity, which reflects the primary function of the upper limbs in Homo sapiens-the precise manipulation of objects-an adaptation to bipedal locomotion. In contrast, the larger PCSA in Pan troglodytes is related to the important role of the supraspinatus in stabilizing the glenohumeral joint during the support phase of knuckle-walking. These functional differences of the supraspinatus in the two species are not reflected in differences in the expression of the MyHC isoforms.

Apendicitis abdominal neonatal. Experiencia en un hospital terciario y revisión de la literatura / Neonatal appendicitis. Our experience and review

Introducción: La apendicitis neonatal (AN) es una enfermedad poco frecuente, cuyo diagnóstico diferencial con otras entidades, como la enterocolitis necrosante, es muy difícil de realizar. Casos clínicos: Presentamos tres casos de AN en nuestro centro atendidos en los últimos 12 años. Resultados: Todos eran recién nacidos prematuros de menos de 1.500 g, con distensión abdominal y signos radiológicos de perforación. Todos sobrevivieron tras la realización de una laparotomía y una apendicectomía. No se encontraron en ningún caso otras enfermedades asociadas, como enfermedad de Hirschsprung (EH) o fibrosis quística (FQ). Conclusiones: La AN es un cuadro poco frecuente, y en nuestra experiencia no parece estar relacionado con la EH ni la FQ. Con un diagnóstico precoz, puede tener buen pronóstico (AU)

Introduction: Neonatal appendicitis (NA) is a rare disease, and differential diagnosis with necrotizing enterocolitis is hard to do. Clinical cases: We present three cases of NA found in our centre in the last 12 years. Results: All of them were premature infants less than 1,500 g, with physical findings of abdominal distention and perforation. All of them survived after laparotomy and appendectomy. No other diseases were associated (Hirschsprung disease, cystic fibrosis). Conclusions: We find neonatal appendicitis to be rare, and in our experience is not related to Hirschsprung disease or cystic fibrosis. With early diagnoses, prognosis seems to be good (AU)

Increased Expression of Aquaporin 9 in Trophoblast From Gestational Diabetic Patients.

Gestational diabetes mellitus is the most frequent pathophysiological alteration in pregnancy, increasing the incidence of complications in both mother and fetus. The macrosomia that occurs in these fetuses may be related with some changes in nutrient transport mechanism in placenta. The presence of aquaporin 9, an aquaglyceroporin, has previously been demonstrated in placenta. We raised the question whether aquaporin 9 expression may be upregulated in placenta from gestational diabetes, thus providing a faster transport of glycerol and water through placenta. We studied 21 placentas (13 controls and 8 gestational diabetes) from cesarean delivery at term. The expression of aquaporin 9 was analyzed by quantitative PCR, immunoblot, and immunohistochemistry. The median values from quantitative PCR were compared by nonparametric tests for independent samples (Mann-Whitney U-test). We have found that trophoblast from gestational diabetes express higher amount of aquaporin 9, which was found statistically significant (p<0.05). The increase in aquaporin 9 expression was confirmed by immunoblot, and localization in the syncytiotrophoblast was checked by immunohistochemistry. The increase in aquaporin 9 expression in placenta from gestational diabetes may contribute to the higher transport rate in this pathology of pregnancy.

Insulin and Leptin Signaling in Placenta from Gestational Diabetic Subjects.

Insulin and leptin receptors are known to share signaling pathways, such as JAK2/STAT-3 (Janus kinase2/signal transduction and activator of transcription3), MAPK (Mitogen activated protein kinase), and PI3K (phosphoinositide 3-kinase). Both positive and negative cross-talk have been previously found in different cellular systems. Gestational diabetes (GDM) is a pathophysiological state with high circulating levels of both insulin and leptin. We have previously found that these 3 signaling pathways are activated in placenta from GDM patients to promote translation, involving the activation of leptin receptor. Now, we have tested the hypothesis that both leptin and insulin receptors might contribute to this activation in a positive way that may become negative when the system is overactivated. We studied the activation of leptin and insulin receptors in placenta from GDM and healthy pregnancies. We have also performed in vitro studies with insulin and leptin stimulation of trophoblast explants from healthy placenta. We have found that both leptin and insulin receptors are activated in placenta from GDM. In vitro stimulation of trophoblast explants with both leptin and insulin at submaximal doses (0.1 nM) potentiated the activation of signaling, whereas preincubation with maximal concentrations of insulin (10 nM) and further stimulation with leptin showed negative effect. Trophoblastic explants from GDM placenta, which presented high signaling levels, had a negative signaling effect when further incubated in vitro with leptin. In conclusion, insulin and leptin receptors have positive effects on signaling, contributing to high signaling levels in GDM placenta, but insulin and leptin have negative effects upon overstimulation.

[Effectiveness of a program of early instillation single chemotherapy in patients with bladder cancer]. / Efectividad de un programa de instilación de quimioterapia precoz en pacientes con cáncer de vejiga.

OBJECTIVE: To determine the effectiveness of early intravesical chemotherapy intervention for patients with non-muscle invasive bladder cancer, before and after a training and inter-professional communication plan. METHOD: Non-experimental prospective longitudinal study of a cohort of 349 patients with endoscopic diagnosis of a non-muscle invasive bladder tumour in Northern Area Health Management of Cadiz between 2010 and 2013 and amenable to postoperative treatment with mitomycin C. RESULTS: The mean rate of patients included in the program was 53.9%. The inclusion rate rose by 79.3% at 3 years. The absolute risk reduction of recurrence for patients receiving treatment is 18.1% (95% CI; 8.81% - 27.48%, p<.001), and the number of patients needed to treat was 5.5 (95% CI; 3.6 - 11.3, p<.001). CONCLUSIONS: A program of early postoperative chemotherapy that includes a plan for evaluation and dissemination of results has achieved a good level of adherence among professionals, obtaining the expected impact on the reduction of early recurrence of non-muscle invasive bladder cancer.

Expression and immunohistochemical localization of leptin receptor in human periapical granuloma.

AIM: To investigate the expression and immunohistochemical localization of leptin receptor (LEPR) in human periapical granulomas. METHODOLOGY: Periapical inflammatory lesions were obtained from extracted human teeth and teeth which underwent periapical surgery. After their histopathological categorization as periapical granulomas (n = 20), they were examined by immunohistochemistry using human LEPR monoclonal antibodies. LEPR mRNA expression was also determined by quantitative real-time PCR (qRT-PCR), and the amount of LEPR protein was analysed by immunoblot. RESULTS: All granuloma samples expressed LEPR. Amongst inflammatory cells, only macrophages showed expression of LEPR. Western blot analysis revealed the presence in the samples of a protein with apparent molecular weight of ~120 kDa, corresponding to the estimated molecular weight of LEPR. The qRT-PCR analysis demonstrated the expression of LEPR mRNA, corresponding the size of the amplified fragment (338 bp), assessed by agarose gel electrophoresis, to that of LEPR mRNA. CONCLUSIONS: Human periapical granulomas express LEPR. In periapical granulomas, only macrophages showed expression of LEPR. This finding suggests that leptin can play a role in inflammatory and immune periapical responses.
