ABSTRACT
BACKGROUND: Functional connectivity alterations in the lateral and medial hypothalamic networks have been associated with the development and maintenance of obesity, but the possible impact on the structural properties of these networks remains largely unexplored. Also, obesity-related gut dysbiosis may delineate specific hypothalamic alterations within obese conditions. We aim to assess the effects of obesity, and obesity and gut-dysbiosis on the structural covariance differences in hypothalamic networks, executive functioning, and depressive symptoms. METHODS: Medial (MH) and lateral (LH) hypothalamic structural covariance alterations were identified in 57 subjects with obesity compared to 47 subjects without obesity. Gut dysbiosis in the subjects with obesity was defined by the presence of high (n = 28) and low (n = 29) values in a BMI-associated microbial signature, and posthoc comparisons between these groups were used as a proxy to explore the role of obesity-related gut dysbiosis on the hypothalamic measurements, executive function, and depressive symptoms. RESULTS: Structural covariance alterations between the MH and the striatum, lateral prefrontal, cingulate, insula, and temporal cortices are congruent with previously functional connectivity disruptions in obesity conditions. MH structural covariance decreases encompassed postcentral parietal cortices in the subjects with obesity and gut-dysbiosis, but increases with subcortical nuclei involved in the coding food-related hedonic information in the subjects with obesity without gut-dysbiosis. Alterations for the structural covariance of the LH in the subjects with obesity and gut-dysbiosis encompassed increases with frontolimbic networks, but decreases with the lateral orbitofrontal cortex in the subjects with obesity without gut-dysbiosis. Subjects with obesity and gut dysbiosis showed higher executive dysfunction and depressive symptoms. CONCLUSIONS: Obesity-related gut dysbiosis is linked to specific structural covariance alterations in hypothalamic networks relevant to the integration of somatic-visceral information, and emotion regulation.

ANTECEDENTS AND OBJECTIVE: Local infiltrations are second line therapy in the treatment of chronic low back pain, although their use is controversial in the literature. Our objective was to compare the effectiveness of 2 types of infiltration at the paravertebral lumbar level in two groups of patients diagnosed with low back pain: corticosteroids, and selective local anaesthetic administered using segmental neural therapy (SNT). MATERIAL AND METHODS: Double-blind clinical trial in 55 patients diagnosed with low back pain in the neurosurgery department of the Hospital Central de la Defensa Gómez Ulla. Patients were randomised to 2 treatment groups to receive either paravertebral injections of corticosteroids or SNT. Outcomes were measured using a visual analogue scale, the Oswestry Disability Index, the Short Form-36, and patient satisfaction at the start of treatment (baseline) and at 3 and 12 months post intervention. RESULTS: The combined treatment group showed a statistically significant improvement in Oswestry Disability Index at 3 months. The SNT group showed a statistically significant improvement in baseline visual analogue scale vs. visual analogue scale at 3 (1.398cm, p=0.001) and 12 months (0.791cm, p=0.007). No differences were observed in the remaining variables measured. The percentage of patients that would repeat the treatment was 81% and 83%, respectively. CONCLUSIONS: Significant pain relief was achieved with SNT, and disability improved with the combined treatment. Although clinical improvement was limited, patients were satisfied. Local infiltrations should be considered as an alternative treatment for chronic low back pain. CLINICAL TRIAL REGISTRATION: This clinical trial was registered at the European Union Clinical Trials Register with EUDRA-CT number 2015-001146-29.

OBJETIVO: Determinar predictores de buena respuesta con el uso de prótesis en la estenosis traqueobronquial. MATERIALES Y MÉTODO: Estudio retrospectivo descriptivo de una serie de casos entre junio de 2014 y junio de 2016. Se revisaron registros clínicos, protocolos operatorios, estudios histopatológicos y de imagen. Se consignaron antecedentes demográficos y clínicos al ingreso y luego del procedimiento, etiología de la estenosis traqueal, necesidad de oxígeno en litros, estadía hospitalaria, morbilidad asociada al procedimiento, indicación de terapia complementaria posterior y sobrevida. Se analizaron los datos con estadística descriptiva y analítica. RESULTADOS: Se realizaron 68 procedimientos, en 44 pacientes, 24 mujeres, el diagnóstico principal fue estenosis traqueal con 40 casos. La etiología neoplásica fue el 88% de los casos. El Performance status (PS) de ingreso fue mayor o igual a 2 en el 68% y posterior al procedimiento disminuyó a 22% p < 0,05. En 36 casos los pacientes requerían al menos 1 L de oxígeno lo que disminuyó en 13 casos posterior a la intervención p < 0,05. El tiempo de hospitalización promedio fue 6,2 días (1-60). En 13 pacientes con patología neoplásica se indicó terapia paliativa complementaria. La morbilidad asociada al procedimiento fue de 2,9% dado por prótesis desplazada y lesión iatrogénica. La sobrevida fue de 27% a un año. CONCLUSIONES: La etiología benigna, el PS previo a la intervención menor o igual a 3, requerimiento de oxígeno de 1 litro y obstrucción tumoral menor al 70% del lumen fueron elementos de buena respuesta.
AIM: Determine good response predictors in use of stent in benign and malignant tracheobronchial stenosis. MATERIAL AND METHODS: We retrospectively reviewed medical records of patients submitted to the procedure in the period 2014 to 2016. Clinical records, operative protocols, and histopathological and imaging studies were reviewed. Demographic and clinical data, performance status (PS) at admission and after the procedure, etiology of tracheal stenosis, need for oxygen in liters (L) Post-intervention, hospital stay, procedure-related morbidity, indication of therapy (Chemotherapy and/or Radiotherapy) and survival. Data were analyzed with descriptive and analytics statistics. RESULTS: A total of 68 procedures were performed in 44 patients, 24 women. Tracheal stenosis 40 cases were diagnosed. The malignant etiology was 88%. The admission PS was greater than or equal to 2 in 68% and 22% after the procedure. The oxygen requirements prior to the procedure were at least 1 L in 36 cases and decreased in 13 cases after the procedure. The average hospitalization period was 6.2 days (1-60). Complementary therapy was indicated in 13 patients; the morbidity associated with the procedure was 2.9%, displaced installation and iatrogenic injury. The one year survival was 27%. CONCLUSIONS: Benign etiology, el PS minor than or equal to 3, oxygen requirements prior to the procedure of 1 L and tumoral obstruction less than 75% were good response predictors in our study.

Altered interactions between the gut mucosa and bacteria during HIV infection seem to contribute to chronic immune dysfunction. A deeper understanding of how nutritional interventions could ameliorate gut dysbiosis is needed. Forty-four subjects, including 12 HIV+ viremic untreated (VU) patients, 23 antiretroviral therapy-treated (ART+) virally suppressed patients (15 immunological responders and 8 non-responders) and 9 HIV- controls (HIV-), were blindly randomized to receive either prebiotics (scGOS/lcFOS/glutamine) or placebo (34/10) over 6 weeks in this pilot study. We assessed fecal microbiota composition using deep 16S rRNA gene sequencing and several immunological and genetic markers involved in HIV immunopathogenesis. The short dietary supplementation attenuated HIV-associated dysbiosis, which was most apparent in VU individuals but less so in ART+ subjects, whose gut microbiota was found more resilient. This compositional shift was not observed in the placebo arm. Significantly, declines in indirect markers of bacterial translocation and T-cell activation, improvement of thymic output, and changes in butyrate production were observed. Increases in the abundance of Faecalibacterium and Lachnospira strongly correlated with moderate but significant increases of butyrate production and amelioration of the inflammatory biomarkers soluble CD14 and high-sensitivity C-reactive protein, especially among VU. Hence, the bacterial butyrate synthesis pathway holds promise as a viable target for interventions.

A pesar de que el cáncer constituye en la mayoría de las series publicadas la patología de base más frecuente para la indicación de Nutrición Parenteral Domiciliaria (NPD), su utilización en pacientes terminales sigue siendo objeto de controversias. Nuestro objetivo ha sido revisar la evolución de los pacientes con cáncer tratados con NPD procedentes del Hospital La Paz con el fin de estudiar su indicación, evolución y complicaciones. Revisamos un total de 9 pacientes oncológicos terminales que habían sido tratados con NPD entre enero de 2000 y diciembre del 2002. Con una edad media de 60,4 años (44-81), el cáncer de base más frecuente era el adenocarcinoma gástrico (44%). La obstrucción intestinal en el contexto de una carcinomatosis peritoneal fue el motivo de indicación en el 89% de los casos y la mediana de supervivencia de 71 días (23-131). La infección del catéter representó la complicación más frecuente con 1,4 episodios/paciente. La existencia de un Equipo de Soporte Domiciliario facilitó el seguimiento de los pacientes, estimándose la NPD como tratamiento proporcionado en el 67% de los casos. El 56% de los pacientes no estaban suficientemente informados de su enfermedad de base. Aunque la NPD es un recurso terapéutico más, del que podemos disponer en algunos pacientes oncológicos terminales, debemos afinar la indicación lo más posible teniendo en cuenta una serie de "garantías sistemáticas" que incluyen el cumplimiento de los criterios clínicos pertinentes, el consentimiento informado y la colegiación en la decisión de todos los profesionales implicados en el seguimiento del paciente. Proponemos un algoritmo de actuación para ayudar a mejorar el proceso de toma de decisiones en estos pacientes (AU)
Background and goals: The assessment of the acceptance of the diets served at the hospital allows the introduction of adjustments to improve the quality of the service provided to hospitalized patients by preventing the complications derived from incorrect nutrition and enhancing their stay in hospital. The goal of the present study was to analyze the acceptance of the menus offered by the Hospital's catering service. Scope of the study: Menus provided by the catering service of the "Sant Joan de Reus" University Hospital. Material and methods: A total of 160 tray meals consumed were assessed, all chosen at random and corresponding to standard diets and special diets, including puréed food. The assessment was made by two dieticians in the hospital´s kitchens. A visual scale was used with the following scores: 0 for a full plate, 1 for residual food amounting to over 75%, 2 from 50% to 75%, 3 more than or equal to 25% and 4 for empty plates. Results: A total of 68 trays containing a standard diet were analyzed, together with 34 containing special diets and 41 with puréed food. The remains on 36 different courses from the standard diet were analyzed. The mean acceptance score was 3.01 ± 1.30 in the case of the first courses, 3.24 ± 1.11 in second courses and 3.53 ± 0.96 for the desserts. As for special diets, a total of 27 different courses were analyzed. The mean acceptance score was 2.87 ± 1.38 in the case of the first courses, 3.02 ± 1.27 in second courses and 3.49 ± 1.22 for the desserts. The first courses of puréed diets received the worst score of all the dishes served, although the overall mean score was good, 2.76 ± 1.5. Conclusions: In general, a good level of acceptance has been observed for the set meals served in the hospital. Knowing which courses have lower acceptance scores allows changes to be proposed to the hospital menus, with their replacement by others with foreseeably better acceptance (AU)

BACKGROUND: In patients with syncope and bundle branch block (BBB), syncope is suspected to be attributable to a paroxysmal atrioventricular (AV) block, but little is known of its mechanism when electrophysiological study is negative. METHODS AND RESULTS: We applied an implantable loop recorder in 52 patients with BBB and negative conventional workup. During a follow-up of 3 to 15 months, syncope recurred in 22 patients (42%), the event being documented in 19 patients after a median of 48 days. The most frequent finding, recorded in 17 patients, was one or more prolonged asystolic pause mainly attributable to AV block; the remaining 2 patients had normal sinus rhythm or sinus tachycardia. The onset of the bradycardic episodes was always sudden but was sometimes preceded by ventricular premature beats. The median duration of the arrhythmic event was 47 seconds. An additional 3 patients developed nonsyncopal persistent III-degree AV block, and 2 patients had presyncope attributable to AV block with asystole. No patients suffered injury attributable to syncopal relapse. CONCLUSIONS: In patients with BBB and negative electrophysiological study, most syncopal recurrences have a homogeneous mechanism that is characterized by prolonged asystolic pauses, mainly attributable to sudden-onset paroxysmal AV block.

AIMS: To assess the diagnostic yield of the head-up tilt test and electrophysiology in different groups of patients with syncope of unknown origin established according to simple clinical criteria. METHODS AND RESULTS: Six hundred consecutive patients with syncope of unknown origin submitted to a tilt test. Two hundred and forty seven of them also underwent electrophysiology. Patients were divided into groups according to age at the time of first syncope, ECG findings and the presence of organic heart disease. Positive responses to the tilt test were more common in patients who had suffered their first syncope at an age equal to or below 65 years (group I) than in older patients (group II) (47% vs 33%, P<0.05, OR 1.8, CI 1.2-2.78), and in patients with a normal ECG and without organic heart disease than in the other subgroups of patients (47% vs 37%, P<0.008, OR 1.6). The lowest rate of positive response was observed in older patients with an abnormal ECG and organic heart disease. Electrophysiology disclosed abnormal findings in group II more often than in group I (23% vs 7%, P<0.001, OR 3.7, CI 1.7-9.2). The diagnostic yield from electrophysiology was higher in patients with an abnormal ECG than in those with a normal ECG (22% vs 3.7%, P<0.0005, OR 7.1), and it was especially low in patients with a normal ECG and without organic heart disease (2.6%). CONCLUSION: The diagnostic yield of the tilt test and electrophysiology differs in groups of patients with syncope of unknown origin, established according to simple clinical criteria. These findings have a bearing on selecting the most appropriate test in a particular patient.
