RESUMEN

En este artículo se describe el proceso de investigación-acción llevado a cabo para la redefinición y el diseño de un programa destinado a niños, niñas y adolescentes con dificultades y/o situaciones conflictivas en el ámbito familiar. El diseño del nuevo programa NAYFA se ha realizado siguiendo los estándares de calidad de los programas basados en la evidencia y mediante un proceso colaborativo entre responsables políticos, profesionales e investigadores. Se utilizó la técnica DAFO para identificar las principales fortalezas y debilidades de las actuaciones previas desarrolladas en diferentes provincias andaluzas. Los resultados pusieron de manifiesto una importante falta de sistematización que se ha tratado de solventar definiendo, mediante un proceso colaborativo y de acuerdo con los criterios de calidad más consensuados, los componentes clave del nuevo programa: fundamentación teórica y metodológica, destinatarios, objetivos, contenidos, condiciones de implementación y diseño de la evaluación. El alto grado de acuerdo de profesionales y responsables con las características propuestas puede contribuir a que la implementación del programa se lleve a cabo con fidelidad al diseño original y, con ello, favorecer su efectividad (AU)


This article describes the action-research process carried out to redefine and design a program for children and adolescents with difficulties and/or conflictive situations in the family. The design of the NAYFA program has been carried out following the quality standards of evidence-based programs and through a collaborative process between policymakers, professionals and researchers. The SWOT technique was used to identify the main strengths and weak-nesses of the previous actions carried out in different Andalucía provinces. The results revealed an important lack of systematization that an attempt has been made to solve by defining, through a collaborative process and in accordance with the most agreed quality criteria, the key components of the new program: theoretical and methodological founda-tions, recipients, objectives, contents, implementation conditions and evaluation design. The high degree of agreement of professionals and managers with the proposed characteristics can contribute to the implementation of the program being carried out with fidelity to the original design and, thus, favor its effectiveness.

RESUMEN

La pandemia de la COVID-19 ha demostrado la fragilidad del mundo globalizado y se está combatiendo mediante una combinación de técnicas y herramientas de ámbitos muy diferentes, desde clínico hasta tecnológico. La aplicación de las nuevas tecnologías ha suscitado el actual gran debate europeo sobre la privacidad. Una de sus manifestaciones es la Orden SND/29/2020, de 27 de marzo, del Ministerio de Sanidad, en la que se prevé el desarrollo de la app DataCOVID de seguimiento digital. Este trabajo tiene por objeto examinar la legalidad y alcance de estas medidas desde la perspectiva del respeto al derecho a la privacidad en el marco de las garantías para los derechos humanos y la protección de datos


The COVID-19 pandemic has demonstrated the fragility of the globalized world and is being fought through a combination of techniques and tools, among which new contact tracing technologies play a fundamental role. These new tracking technologies have sparked the current great European debate on privacy. One of its manifestations is Order SND/29/2020, of March 27, approved by the Ministry of Health of the Government of Spain, which provides for the development of a website and a contact tracing app DataCOVID. This work aims at examining the legality and scope of the measures adopted in the Ministerial Order considering its implications for the respect of the right to privacy and data protection from the perspective of human rights guarantees

RESUMEN

BACKGROUND: Classification of growth hormone (GH) - secreting tumors by the granular pattern might predict their clinical behavior in acromegalic patients. There are several other prognostic factors. AIM: To compare the features at presentation and cure rates of patients with GH secreting tumors according to the granular pattern, and to define independent prognostic factors for surgical treatment in these patients. MATERIAL AND METHODS: A retrospective, observational study of 85 active acromegalic patients surgically treated in two medical centers. RESULTS: Seventy-four patients (87%) were classified as having densely granulated (DG) and 11 (13%) as sparsely granulated (SG) tumors. The latter were less active biochemically, had a higher rate of macroadenoma and cavernous sinus invasion and had a lower rate of biochemical cure than the DG group. Several characteristics were associated with disease persistence but only age (Odds ratio (OR) = 0.93) and cavernous sinus invasion (OR = 21.7) were independently associated in the logistic regression model. CONCLUSIONS: The sparsely granulated pattern is associated with a more aggressive behavior, but the main determinants of prognosis are age and cavernous sinus invasion.

RESUMEN

OBJECTIVES: To determine ultrasound (US) and clinical findings of thyroid microcalcifications in the absence of a nodule and their association with the risk of malignancy. METHODS: The Institutional Review Board approved a 5-year retrospective study. Twenty-one patients with clustered or scattered thyroid microcalcifications in the absence of nodules on US images who underwent fine-needle aspiration biopsies (FNABs) were included. Demographic and clinical data, US findings, and pathologic results were registered. Patients with a suspicion of malignancy or papillary thyroid carcinoma (PTC) on FNAB underwent thyroidectomy. Patients with benign results on FNAB underwent clinical and US surveillance. RESULTS: The mean age of the 21 patients was 33.2 years (29.5 years in patients with PTC patients and 39.4 years in those with benign findings; P = .034). Eleven of 21 patients had clustered microcalcifications (9 had cancer), and 10 of 21 patients had scattered microcalcifications (4 of 10 had cancer; P = 0.063). Sixty-two percent of the patients had FNAB findings that were suspicious for cancer or had a diagnosis of cancer. Eleven of 13 patients had surgical thyroidectomy performed in our institution; in all cases, Hashimoto thyroiditis was confirmed. Univariate and multivariate analysis showed that only age was significant (odds ratio, 0.9; P < .05). CONCLUSIONS: Our study suggests that the presence of thyroid microcalcifications without a nodule is suspicious for PTC. We found that both patterns were suspicious for PTC, particularly in young patients. Special concern arises for those clustered microcalcifications on a background of Hashimoto thyroiditis.

RESUMEN

BACKGROUND: Cortisol dysregulation has a potential role in depression. AIM AND METHODS: We evaluated depressive symptoms using the Hamilton Rating Scale for Depression in 48 primary care subjects without history of previous or current depression and its association with cortisol dysregulation (morning plasma cortisol, 24-hour urinary free cortisol and cortisol metabolites). Presence of metabolic syndrome and inflammatory parameters were also assessed. RESULTS: Hamilton Rating Scale for Depression correlated significantly with morning cortisol, but not with urinary free cortisol or metabolites. A significant increase in morning cortisol by Hamilton groups (asymptomatic ≤8; mild to moderate: 9-18; moderate to severe: ≥19) was observed even when adjusted by age/gender. We observed no association of depressive symptoms with metabolic or inflammatory parameters. CONCLUSION: Depressive symptoms in primary care subjects not consulting for their mood are associated with higher morning plasma cortisol, but not urinary cortisol or its metabolites. These observations suggest that systemic hypercortisolism and related metabolic disorders are not observed in mild/initial states of depressive disorders.

RESUMEN

RESUMEN: El odontólogo como profesional integral del área de la salud, debe tener conocimiento acerca de distintas manifestaciones bioquímicas que pueden tener repercusión en la cavidad oral. El objetivo del trabajo fue determinar las manifestaciones bioquímicas y alteraciones en biomarcadores salivales en la cavidad oral producto de la fibrosis quística o del consumo crónico de medicamentos para el tratamiento de la FQ. Se seleccionó un total de cinco personas con fibrosis quística y cuatro personas sanas, pertenecientes a la ciudad de Concepción en la Octava Región de Chile. Se midió pH salival, capacidad buffer, concentración de proteínas totales, tasa de flujo salival estimulado y se determinó presencia de ciertas enzimas salivales en pacientes que padecen la enfermedad. Se pudo evidenciar que el pH salival en sujetos con fibrosis quística tiende a ser mayor a los valores de referencia, la tasa de flujo salival es mucho menor al igual que la capacidad buffer, la concentración de proteínas totales en saliva se encuentra igual a los valores de referencia y se determinó la presencia biomarcadores salivales a través de la técnica de electroforesis. La fibrosis quística afecta de muchas formas a las personas que la padecen, genera cambios a nivel de los biomarcadores salivales como también en la cavidad oral, por lo que el odontólogo debe estar capacitado para identificar estos cambios y poder tratar de la mejor manera a todo tipo de paciente.


ABSTRACT: The dentist as an integral health professional must have knowledge of various biochemical manifestations that may have repercussions on the oral cavity. The objective of the study was to determine the biochemical manifestations and salivary biomarker alterations in the oral cavity resulting from cystic fibrosis or chronic consumption of drugs for the treatment of CF. We selected a total of five people with cystic fibrosis and four healthy people, from the city of Concepcion in the eighth region of Chile. Salivary pH, buffer capacity, total protein concentration, stimulated salivary flow rate and the presence of certain salivary enzymes were measured in patients suffering from the disease. It was observed that the salivary pH in subjects with cystic fibrosis tends to be higher than the reference values, the salivary flow rate and buffer capacity are less than normal, the total protein concentration in saliva is equal to the reference values and the presence of salivary biomarkers was determined through the electrophoresis technique. Cystic fibrosis affects those who suffer the disease in many ways, it generates changes at the salivary biomarker level, as well as in the oral cavity. The dentist must therefore, be able to identify these changes in order to treat them in the best possible approach for all types of patients.

RESUMEN

Long-term non-invasive ventilation (NIV) is a common modality of breathing support used for a range of sleep and respiratory disorders. The aim of this scoping review was to provide a summary of the literature relevant to long-term NIV use in children. We used systematic methodology to identify 11,581 studies with final inclusion of 289. We identified 76 terms referring to NIV; the most common term was NIV (22%). Study design characteristics were most often single center (84%), observational (63%), and retrospective (54%). NIV use was reported for 73 medical conditions with obstructive sleep apnea and spinal muscular atrophy as the most common conditions. Descriptive data, including NIV incidence (61%) and patient characteristics (51%), were most commonly reported. Outcomes from sleep studies were reported in 27% of studies followed by outcomes on reduction in respiratory morbidity in 19%. Adverse events and adherence were reported in 20% and 26% of articles respectively. Authors reported positive conclusions for 73% of articles. Long-term use of NIV has been documented in a large variety of pediatric patient groups with studies of lower methodological quality. While there are considerable data for the most common conditions, there are fewer data to support NIV use for many additional conditions.

RESUMEN

BACKGROUND: The antidepressant bupropion has received increasing attention as a pharmacological tool to treat addiction although little is known about its effects on social behaviour in adolescents. The present study aimed to evaluate if environmental housing conditions influence bupropion's actions on social behaviour of adolescent mice. METHODS: Mice were either group- or individually housed for 2-weeks and then randomly divided into 2 cohorts: half of the mice remained in the initial housing condition and the other half were changed to isolated conditions for further 2-weeks. The following groups were compared: isolated/isolated (ISO/ISO), isolated/group-housed (ISO/GR), group-housed/isolated (GR/ISO), and group-housed/group-housed (GR/GR). The effects of bupropion (40, 20, 10mg/kg) or saline on social interaction were assessed for each housing condition. Social encounters were evaluated using ethological analysis. RESULTS: Data showed significant effects of bupropion on grooming and digging. This drug diminished time mice allocated to these behavioural categories in all housing conditions. In ISO/GR and GR/ISO conditions, bupropion increased environmental exploration (non-social exploration and exploration from a distance), reduced social investigation and increased avoidance/flee and defence/submission behaviours. An augment of avoidance/flee during social interactions was observed in bupropion-treated mice in GR/GR housing condition. CONCLUSION: These results suggest that this drug exhibits anxiogenic-like properties in social encounters between adolescent mice, especially when a transition in housing conditions has been experienced during this period. Changes in housing conditions may be a useful model for evaluating the effects of bupropion on social behaviour and the role of environmental housing conditions.

RESUMEN

BACKGROUND: Adolescence is characterized by major neurobiological changes, and the effects of some psychoactive drugs seem to differ between adolescents and adults. Bupropion, an antidepressant that is also used to treat nicotine addiction, induces behavioral actions in both adolescent and adult rodents. However, the effects of this drug on spatial ability have not been compared in animals at different stages of their development. The present study was conducted to assess the effects of bupropion on spatial learning and memory in adolescent and adult mice. METHODS: Adolescent (post-natal day: PND35-36) and adult (PND >65) NMRI mice received bupropion (10, 20 and 40mg/kg) or saline during the acquisition (4 trials/day on 5 consecutive days) of a Morris water maze (MWM) task. Retention was evaluated with a probe trial performed after the acquisition phase. RESULTS: Data showed that age did not affect performance of the task. However, the factor Drug treatment reached statistical significance, with high doses of bupropion (40 and 20mg/kg) impairing acquisition of the MWM test in adolescents. The drug did not induce detrimental effects on the acquisition or retention of the task in adults. CONCLUSION: Bupropion impairs acquisition of the spatial task in adolescent but not in adult mice. It does not seem to alter retrieval of previously acquired spatial information in either adolescents or adults. Our findings suggest that, during the adolescent period, mice are more vulnerable to the actions of bupropion on spatial learning.

RESUMEN

BACKGROUND: High sodium intake has been associated with various noncommunicable disease like hypertension, cardiovascular disease, or stroke. To estimate accurately sodium intake is challenging in clinical practice. We investigate the usefulness and limitations of assessing sodium intake simultaneously by dietary assessment and urinary samples in both children and adults. METHODS: We used a cross-sectional study design inviting 298 Chilean subjects (74 children and 222 adults) aged between 9 and 66 years of both genders. Sodium intake by dietary assessment was obtained from Chilean food composition data, based on FAO tables. Sodium and creatinine excretion were measured in 24-hour urine samples, in all participants. RESULTS: Adequate urinary collection was obtained in 81% of children (59/74) and 61% of adults (135/222). The mean sodium intake by dietary assessment was similar to the sodium excretion in 24 hours (3,121±1,153mg/d vs. 3,114±1,353mg/24h, P = nonsignificant) in children but was significantly lower (3,208±1,284mg/d vs. 4,160±1,651mg/24h, P < 0.001) in adults. In both children and adults, sodium intake correlated with urinary sodium excretion (r = 0.456, P < 0.003 and r = 0.390, P < 0.001, respectively). Secondary analyses also suggested that the dietary assessment was more inaccurate in overweight adult subjects. CONCLUSIONS: Our results showed that average sodium intake was higher than recommended in both children and adults (WHO ≤2,000mg/d). The sodium intake estimated by dietary assessment correlated with urinary excretion in all subjects, but in obese adults was more inaccurate than in children. Future studies to validate the appropriate test to assess sodium intake by age and nutritional status are warranted.

RESUMEN

CONTEXT: Primary pigmented nodular adrenocortical disease (PPNAD) is a rare cause of ACTH-independent Cushing's syndrome that may occur in an isolated form or as part of Carney complex. The diagnosis of this disease can be difficult preoperatively because computed tomography (CT) scan can be normal or suggest unilateral adrenal lesion, which can impede the correct diagnosis of bilateral adrenal disease. OBJECTIVE: The aim of our study was to describe the results of preoperative imaging (adrenal [6ß-(131)I]iodomethyl-19-norcholesterol] [NP-59] scintigraphy and standard adrenal CT scan) and their correlations with clinical, pathological, and genetics investigations in patients with PPNAD. PATIENTS AND METHODS: Seventeen patients with ACTH-independent syndrome due to PPNAD were investigated with a standard adrenal CT scan and NP-59 scintigraphy. Hormonal, pathological, and genetics data were analyzed. RESULTS: Four males and 13 females (median age, 27 y) were included. PPNAD was isolated in 11 patients (with PRKAR1A mutation, n = 7; and without PRKAR1A mutation, n = 4) and was associated with extra-adrenal manifestations of Carney complex in six patients (with PRKAR1A mutation, n = 4; and without PRKAR1A mutation, n = 2). Standard adrenal CT scan revealed micronodules in 11 patients, macronodules in three patients, and was normal in three patients. All patients demonstrated bilateral adrenal radiocholesterol uptake. Adrenal uptake was asymmetrical in 10 of 17 patients (59%). Asymmetrical uptake correlated with the presence of macronodules at pathological analysis (P = .03). CONCLUSION: Standard adrenal CT scan most often reveals micronodules but there is no specific CT imaging. NP-59 scintigraphy always shows a bilateral adrenal uptake confirming the bilateral nature of the disease, but asymmetrical scintigraphic uptake can be observed in patients with macronodules.

RESUMEN

El dermatofibroma es una frecuente lesión cutánea con muchos subtipos sobre la base de la gran variedad de patrones histológicos. La presencia de patrones inusuales y/o la coexistencia de 2 o más patrones en una misma lesión causan dificultades diagnósticas. La variante epitelioide es un infrecuente y poco reconocido subtipo de dermatofibroma y debería ser diferenciado de otros tumores benignos y malignos cutáneos con patrón epitelioide. Nosotros presentamos un nuevo caso de dermatofibroma que combina características epitelioides y esclerosantes, y revisamos la literatura, en particular con respecto a acontecimientos morfológicos y de diagnóstico diferencial (AU)


Dermatofibroma is a common skin lesion with many subtypes based on the great variety of architectural patterns. The presence of unusual patterns and/or coexistence of two or more patterns in the same lesion can cause diagnostic difficulties. The epithelioid variant is an uncommon and poorly recognized subtype of dermatofibroma and should be differentiated from other benign and malignant skin tumours with an epithelioid pattern. We present a case of dermatofibroma with both epithelioid and sclerosing features and review the literature paying particular attention to morphology and differential diagnosis (AU)

RESUMEN

INTRODUCTION: Non-invasive ventilation (NIV) in children has become an increasingly common modality of breathing support where pressure support is delivered through a mask interface or less commonly through other non-invasive interfaces. At this time, NIV is considered a first-line option for ventilatory support of chronic respiratory insufficiency associated with a range of respiratory and sleep disorders. Previous reviews on the effectiveness, complications and adherence to NIV treatment have lacked systematic methods. The purpose of this scoping review is to provide an overview of the evidence for the use of long-term NIV in children. METHODS AND ANALYSIS: We will use previously established scoping methodology. Ten electronic databases will be searched to identify studies in children using NIV for longer than 3 months outside an intensive care setting. Grey literature search will include conference proceedings, thesis and dissertations, unpublished trials, reports from regulatory agencies and manufacturers. Two reviewers will independently screen titles and abstracts for inclusion, followed by full-text screening of potentially relevant articles to determine final inclusion. Data synthesis will be performed at three levels: (1) an analysis of the number, publication type, publication year, and country of publication of the studies; (2) a summary of the study designs, outcomes measures used; (3) a thematic analysis of included studies by subgroups. ETHICS AND DISSEMINATION: This study will provide a wide and rigorous overview of the evidence on the use of long-term NIV in children and provide critical information for healthcare professionals and policymakers to better care for this group of children. We will disseminate our findings through conference proceedings and publications, and evaluate the results for further systematic reviews and meta-analyses.

RESUMEN

BACKGROUND: Rac1 upregulation has been implicated in salt-sensitive hypertension as a modulator of mineralocorticoid receptor (MR) activity. Rac1 could affect the expression of oxidative stress markers, such as hemoxigenase-1 (HO-1) or nuclear factor-B (NF-κB), and the expression of neutrophil gelatinase-associated lipocalin (NGAL), a cytokine upregulated upon MR activation. AIM: We evaluated RAC1 expression in relation of high salt intake and association with MR, NGAL, HO-1, and NF-κB expression, mineralo- and glucocorticoids levels, and inflammatory parameters. SUBJECTS AND METHODS: We studied 147 adult subjects. A food survey identified the dietary sodium (Na) intake. RAC1 expression was considered high or low according to the value found in normotensive subjects with low salt intake. We determined the gene expression of RAC1, MR, NGAL, HO-1, NF-κB, and 18S, isolated from peripheral leukocytes. We measured aldosterone, cortisol, sodium, potassium excretion, metalloproteinase (MMP9 y MMP2), and C-reactive protein. RESULTS: We identified 126 subjects with high Na-intake, 18 subjects had high, and 108 low-RAC1 expression. The subjects with high-RAC1 expression showed a significant increase in MR (P = 0.0002), NGAL (P < 0.0001) HO-1 (P = 0.0004), and NF-κB (P < 0.0001) gene expression. We demonstrated an association between RAC1 expression and MR (R sp 0.64; P < 0.0001), NGAL (R sp 0.48; P < 0.0001), HO-1 (R sp 0.53; P < 0.0001), and NF-κB (R sp0.52; P < 0.0001). We did not identify any association between RAC1 and clinical or biochemical variables. CONCLUSIONS: RAC1 expression was associated with an increase in MR, NGAL, NF-κB, and HO-1 expression, suggesting that RAC1 could be a mediator of cardiovascular damage induced by sodium, and may also useful to identify subjects with different responses to salt intake.

RESUMEN

BACKGROUND: There is consensus in promoting the selective use of glucocorticoids (GC) in the peri-operative period of transsphenoidal surgery (TE) for pituitary adenomas (PA). AIM: To evaluate the safety of a selective glucocorticoid administration protocol and the usefulness of immediate postoperative cortisol levels as a predictor of final eucortisolism. PATIENTS AND METHODS: Clinical and biochemical data from 40 patients aged 27 to 78 years (65% males) were prospectively collected. Exclusion criteria were previous use of GC, apoplexy and Cushing disease. Patients with pre-operative short synthetic ACTH test (SST) > 18 µg/dl or basal cortisol > 15 µg/dl did not receive GC. A morning serum cortisol (SC) threshold of 10 µg/dl in postoperative days one to three was used to decide a discharge without GC. Hypotension, dizziness or nausea, requirement of increased dose of corticosteroids, hospitalizations and emergency service visits were investigated, as well as surgical and endocrinological complications. Corticotropic status was evaluated three months after surgery. RESULTS: Macroadenomas were present in 87% of patients. Median hospital stay was 4 days and follow up lasted 9 months. No differences were found in gender, age or tumor size between patients who received or not GC (35 and 65% respectively). Eighty five percent of patients were discharged without GC and all of them had normal corticotropic function three months after surgery. A SC ≥ 15 µg/dl had 100% specificity to predict eucortisolism. CONCLUSIONS: Selective glucocorticoid administration is safe. A normal corticotropic function before surgery and in the immediate postoperative period are useful to identify patients who do not need GC.

RESUMEN

La lesión lipomatosa fibrohistiocítica hemosiderótica, también llamada tumor fibrolipomatoso hemosiderótico, es una rara y recientemente descrita entidad fibrolipomatosa. Inicialmente considerada como el resultado de un proceso inflamatorio reactivo secundario a trauma o enfermedad vascular, evidencias más recientes sugieren que pueda ser de origen neoplásico. Presentamos el caso de una mujer de 57 años y revisamos la literatura, particularmente con respecto a acontecimientos genéticos, morfológicos, inmunohistoquímicos y de diagnóstico diferencial, con especial atención a su relación con el tumor angiectásico hialinizante pleomorfo precoz y el sarcoma fibroblástico mixoinflamatorio (AU)


A hemosiderotic fibrohistiocytic lipomatous lesion, also called hemosiderotic fibrolipomatous tumour, is a newly described, rare fibrolipomatous entity. Initially considered to be the result of a reactive inflammatory process subsequent to trauma or vascular disease, recent evidence suggests that it may have a neoplastic origin. We report a case occurring in a 57-year-old woman and review recent reports on current genetic developments, morphology, immunohistochemistry and differential diagnosis, paying special attention to its relation with early pleomorphic hyalinizing angiectatic tumour and myxoinflammatory fibroblastic sarcoma (AU)
