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.

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

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, the Spanish Diabetes Society, and the Spanish Society of Internal Medicine.

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.

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.

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.

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.

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.

Activated translation signaling in placenta from pregnant women with gestational diabetes mellitus: possible role of leptin.

Placentas from gestational diabetes (GDM) suffer from structural and functional changes including overgrowth. That is why we aimed to study [³H]-leucine incorporation into protein in addition to translation signaling in placenta from GDM. Thus, we investigated the expression of leptin and leptin receptor (LEPR), as well as the activation state of signaling proteins regulating protein synthesis, such as mTOR, S6 Kinase, EIF4E-BP1, EIF4E, and eEF2 by measuring protein phosphorylation by immunoblot. [³H]-Leucine incorporation into protein also was determined in trophoblastic placenta explants from GDM and control pregnancy. We found that leptin and LEPR expression are increased in placentas from GDM and the translation machinery activity as well as [³H]-leucine incorporation into protein were higher in placentas from GDM compared with placentas from control pregnancy. In conclusion, protein synthesis rate is increased in placenta from GDM patients, and this may be due, at least in part, by the activation of translation signaling. The increased expression of leptin and LEPR may contribute to these effects. These results may provide a possible mechanism for the previously observed increase in placenta growth in GDM.

Leptin expression in healthy and inflamed human dental pulp.

AIM: To investigate the expression of leptin in healthy and inflamed human dental pulp. METHODOLOGY: Twenty-one pulp samples were obtained from freshly caries- and restoration-free extracted human third molars. In seven-third molars (inflamed pulp group), inflammation was induced prior to extraction. Pulp samples were processed, and leptin expression was determined by quantitative real-time PCR (qRT-PCR) and the amount of leptin by immunoblot. RESULTS: All healthy and inflamed dental pulp samples expressed leptin. Western blot analysis revealed the presence of a protein with an apparent molecular weight of ~16 kDa in human dental pulp, which corresponds to the estimated molecular weight of leptin. The expression of leptin mRNA in dental pulp was confirmed by qRT-PCR analysis, and the size of the amplified fragments (296 bp for leptin and 194 bp for cyclophilin) was confirmed by agarose gel electrophoresis. The expression of leptin in the inflamed pulp group was significantly greater (P < 0.05) than in healthy teeth. The relative amount of leptin in inflamed pulps was almost twice than in healthy pulps. CONCLUSIONS: For the first time, the presence of leptin in human dental pulp tissues has been demonstrated. The upregulation of leptin expression in inflamed pulp samples suggests that leptin can play a role in pulpal inflammatory and immune responses.

Expression of myosin heavy chain isoforms in the human supraspinatus muscle: variations related to age and sex.

The contractile function of skeletal muscles is primarily regulated by the expression of myosin heavy chain (MHC) isoforms. Adult human skeletal muscles express three MHC isoforms (MHC-I, MHC-IIa and MHC-IIx). The muscles mainly expressing MHC-I are slow but resistant to fatigue, while those with major expression of MHC-IIa and MHC-IIx are fast and powerful but less resistant to fatigue. In this study, mRNA levels of the MHC isoforms were assessed in 24 human supraspinatus muscles by reverse-transcription polymerase chain reaction. The average expression of the MHC-I isoform was 36.72%, that of the MHC-IIa isoform was 33.52%, and the average expression of the MHC-IIx isoform was 29.76%. The higher average expression of the two MHC-II isoforms taken together (63.28%) indicates that the human supraspinatus muscle is a powerful, fast muscle with relatively low resistance to fatigue, in accordance with its role in the elevation of the upper extremity. In women, and more markedly in older women, the trend towards upregulation of the fast MHC-II isoforms and downregulation of the slow MHC-I isoform, which is absent in males, may improve our understanding of possible causes of the subacromial impingement syndrome.

[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.

Sam68 mediates leptin-stimulated growth by modulating leptin receptor signaling in human trophoblastic JEG-3 cells.

BACKGROUND: Sam68, a member of the signal transduction and activation of RNA metabolism (STAR) family of RNA-binding proteins, has been previously implicated as an adaptor molecule in different signaling systems, including leptin receptor (LEPR) signaling. LEPR activation is known to stimulate JAK-STAT, MAPK and PI3K signaling pathways, thus mediating the biological effects of leptin in different cell types, including trophoblastic cells. We have recently found that leptin stimulation also promotes the overexpression and tyrosine phosphorylation of Sam68 in human trophoblastic JEG-3 cells, suggesting a role for Sam68 in leptin signaling and action in these cells. In the present work, we have studied the participation of Sam68 in the main signaling pathways activated by LEPR to increase growth and proliferation in trophoblastic JEG-3 cells. METHODS: We used an antisense strategy to down-regulate Sam68 expression in these cells, and we studied LEPR signaling by immunoprecipitation and poly-U affinity precipitation and by analyzing phosphorylation levels of signaling proteins by immunoblot. The effect of leptin on protein synthesis and proliferation was studied by ³[H]-leucine and ³[H]-thymidine incorporation. RESULTS: Sam68 knockdown impaired leptin activation of JAK-STAT, PI3K and MAPK signaling pathways in JEG-3 cells. We have also found that leptin-stimulated Sam68 tyrosine phosphorylation is dependent on JAK-2 activity, since the pharmacological inhibitor AG490 prevents the phosphorylation of Sam68 in JEG-3 cells. Finally, the trophic and proliferative effect of leptin in trophoblastic cells is dependent on Sam68 expression, since its down-regulation impaired the leptin-stimulated DNA and protein synthesis. CONCLUSIONS: These data demonstrate that Sam68 participates in the main signaling pathways of LEPR to mediate the trophic and proliferative effect of leptin in human trophoblastic cells.

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

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.

Testing hypotheses of dietary reconstruction from buccal dental microwear in Australopithecus afarensis.

A recent study of occlusal microwear in Australopithecus afarensis described this species as an opportunistic dweller, living in both forested and open environments and greatly relying on fallback resources and using fewer food-processing activities than previously suggested. In the present study, analysis of buccal microwear variability in a sample of A. afarensis specimens (n=75 teeth) showed no significant correlations with the ecological shift that took place around 3.5Ma in Africa. These results are consistent with the occlusal microwear data available. In fact, significant correlations between buccal and occlusal microwear variables were found. However, comparison of the buccal microwear patterns showed clear similarities between A. afarensis and those hominoid species living in somewhat open environments, especially the Cameroon gorillas. A diet based mainly on succulent fruits and seasonal fallback resources would be consistent with the buccal microwear patterns observed.

[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.

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)

Acute febrile neutrophilic dermatosis (Sweet's syndrome) associated with post-myocardial infarction syndrome (Dressler's syndrome).

A case of Sweet's syndrome (acute febrile neutrophilic dermatosis) occurred in a patient with post-myocardial infarction syndrome (Dressler's syndrome). Although Sweet's syndrome has been described in association with leukemias, other malignant disorders, and a variety of chronic inflammatory disorders, it has not been reported associated with Dressler's syndrome. Sweet's syndrome is reviewed with regard to its associations and to its pathogenesis.
