Trastorno eréctil ¿Qué factores pueden afectar a su gravedad? Un estudio descriptivo-correlacional / Erectile dysfunction: what factors affect its severity? A descriptive correlate story

Una de las disfunciones sexuales más comunes es el trastorno eréctil (TE). Pretendemos identificar factores asociados a la gravedad del TE. Treinta y seis hombres, entre 18 y 70 años, que presentan un diagnóstico de TE, basado en los criterios DSM-V, han sido evaluados a través de una entrevista clínica y de una batería de 7 cuestionarios (IIEF, SCL-90, PDQ-4, PSWQ, STAI, SSES, SSEI). La metodología se centró en un estudio cuantitativo, de tipo descriptivo-correlacional de diseño ex post facto con muestreo por conveniencia. Los resultados del modelo de regresión final muestran que la autoeficacia sexual, determinadas tendencias de personalidad y la sintomatología de depresión, somatización, obsesión-compulsión y ansiedad son factores asociados a la gravedad del TE, explicando el 51,3% de la varianza. Poder identificar aquellos factores asociados a la gravedad del TE, puede tener una relevante importancia para poder trabajar en su prevención y mejorar la orientación de las intervenciones psicológicas.(AU)

One of the most common sexual dysfunctions is erectile disorder (ED). Therefore, this research aims to identify factors associated with the severity of ED. Thirty-six men, aged 18 to 70 years, with a diagnosis of ED, based on DSM-V criteria, were assessed by means of a clinical interview and a battery of 7 questionnaires (IIEF, SCL-90, PDQ-4, PSWQ, STAI, SSES, SSEI). The methodology focused on a quantitative, descriptive-correlational study of ex post facto design with convenience sampling. The results of the final regression model shows that sexual self-efficacy, certain personality tendencies and the symptomatology of depression, somatization, obsession-compulsion and anxiety are factors associated with the severity of TE, explaining 51.3% of the variance. Being able to identify those factors associated with the severity of TE may be of relevant importance in order to work on its prevention and improve the orientation of psychological interventions.(AU)

Reflexiones sobre la aplicación de la "Ley Trans” en la atención sanitaria / Reflections on the application of the “trans law” in health care

En este artículo se reflexiona sobre la reciente ley aprobada por el Congreso de los Diputados conocida como Ley 4/2023 para la igualdad real y efectiva de las personas trans y para la garantía de los derechos de las personas LGTBI (BOE-A-2023-5366, 2023). Se analizan inicialmente los artículos que más polémica han causado en el ámbito social, que son los relativos a la rectificación registral (Art. 43-51), y posteriormente los que hacen referencia directa o indirectamente a aspectos sanitarios; 1) el que prohíbe de métodos, programas o las llamadas terapias de conversión (Art. 17), 2) los que definen cómo debe ser en términos generales la atención sanitaria (Art. 56-59), y 3) finalmente el único artículo que menciona a los menores (Art 70). Se comenta que el término utilizado de persona trans, al englobar un amplio abanico de diversidades sexuales, variantes y expresiones de género, incluye tanto a personas que necesitan una atención médica como a otras que no. Se plantea que la rectificación registral acorde con esta ley 2023 al no precisar ningún requisito para su inscripción, ofrece menos garantías que la legislación ya existente de marzo 2007. Se considera que las directrices de la nueva ley se están traduciendo en una toma de decisiones por parte del usuario sin disponer de una valoración o diagnóstico por el equipo de profesionales que atienden el caso. Se destaca que la ley no incluye ninguna referencia a la atención por salud mental. Y en conjunto, se concluye que el texto aprobado, en el ámbito sanitario, puede mermar la calidad de la asistencia integral, sobre todo en menores, o personas con identidades complejas, dudosas, o con comorbilidades, que pueden generar discrepancia entre el criterio del profesional y la opinión del usuario.(AU)

Depression in internal medicine inpatients at the time of hospital discharge and referral to primary care

Background and objectives. This is the first multi-center study intended to document the prevalence, characteristics, and associations of depression in Medicine patients at the time of hospital discharge and their referral to Primary Care (PC). Methods. Adult patients randomly selected among consecutive admissions to Medicine wards in 8 hospitals in Spain, covering health districts, were examined in a two-phase 'case-finding' procedure. Standardized, Spanish versions of instruments were used, including the Standardized Polyvalent Psychiatric Interview (SPPI) and Cumulative Illness Rating Scale (CIRS). Cases of depression were diagnosed according to ICD-10 general hospital research criteria. Results. Three hundred and twelve patients with treatable depression and 777 non-depressed controls were identified. In a conservative estimate, the global prevalence of major depression was 7.1%, dysthymia 4.2% and adjustment depression 7.1%, and 51.9% of cases were of moderate/ severe intensity. Depression was more frequent in women, the differences being significant in all categories of depression. The prevalence of depression was lower in individuals aged 85 or more years, the differences being significant in cases of both dysthymia and adjustment depression. A clear pattern of decreasing prevalence with age was observed in women. The depressed had as an average five medical systems affected, and higher CIRS scores compared with the controls, the differences being significant in cases of both major depression and dysthymia. Conclusions. This is the first report showing a considerable prevalence of treatable cases of depression in Medicine patients at the time of hospital discharge and referral to PC. Depression is associated with the severity of the medical condition, and differences observed by age and sex have clinical implications.

Case study of pipeline failure analysis from two automated vacuum collection system.

Conventional municipal waste management systems based on collecting and storing waste for future management are cost-effective and flexible. These systems present significant problems such as odours, plagues and hygiene problems caused by their storage and greenhouse gas emissions from garbage trucks used for the transport of waste. The Automated Waste Collection System (AWCS) and Automated Vacuum Waste Collection (AVWC) systems, in which waste is transported directly underground to the processing plants, are efficient collection systems and respectful of the environment as alternatives to traditional systems. The pneumatic system reduces the value of the per capita generation of general waste. The present study explains the origin of pipe failure in two different AWCS factories, as well as the identification of the failure phenomena. To carry out the study, a classification of 90 failure cases by primary cause was performed, followed by recommendations to avoid these failures in the future. Moreover, a computational fluid dynamics (CFD) simulation was performed in order to help in the failure determination and the key recommendations to avoid the most common and frequent failures.

Determining personalized treatment by gene expression profiling in metastatic breast carcinoma patients: a pilot study

Purpose: The present study evaluates the massive study of gene expression in metastatic breast carcinoma (MBC) patients using microarray gene expression profiling (MAGE) complemented with conventional sequencing, immunohistochemistry (IHC) and fluorescent "in situ" hybridization (FISH), seeking to optimize the treatment in a subset of heavily pretreated patients and with limited life expectancy. Patients, material and methods: MBC patients in hormone therapy progression with survival expectancy of at least 3 months (m) have been included. The MAGE contains gene probes representing genes known to potentially interact with available drugs as cited in the literature. Results: Thirty-nine procedures were performed from October 2010 to April 2016. Within the 30 evaluable procedures, considering all hormonal manipulations as a single line, the patients had received a median of 4 treatment lines prior to MAGE (range 1-7). Progression was observed in 6 cases, stable disease (SD) in 7 cases and partial response (PR) in 16 cases, which implies a clinical benefit rate (SD + PR) of 76%. Actuarial median progression-free survival (PFS) was 6 m (95% CI 2.5-9.5) in patients with clinical benefit. The median overall survival (OS) for the entire series was 11 m (95% CI 2.2-19.8). Conclusion: Data presented here indicate that the use of MAGE provides relevant information to establish personalized treatment in frail patients with limited life expectancy in which therapeutic futility is a particularly difficult burden to assume

Parathormone Levels Are Independently Associated with the Presence of Left Ventricular Hypertrophy in Patients with Coronary Artery Disease.

BACKGROUND: Abnormalities of mineral metabolism and inflammation may affect the cardiovascular system. We have assessed the relationship of left ventricular hypertrophy (LVH) with inflammation and mineral metabolism. METHODS: LVH was measured in 146 outpatients with stable coronary artery disease (SCAD) using echocardiography. Calcidiol (a vitamin D metabolite), parathyroid hormone (PTH), fibroblast growth factor-23, high-sensitivity C-reactive protein, MCP-1 (monocyte chemoattractant protein-1), galectin-3, NGAL (neutrophil gelatinase-associated lipocalin), and sTWEAK (soluble TNF-related weak inducer of apoptosis) plasma levels were studied. RESULTS: LVH, defined as septal thickness ≥11 mm, was present in 19.9% of cases. These patients were older [75.0 (61.0-81.0) vs 64.0 (51.0-76.0) years; p=0.002], had higher prevalence of left ventricular ejection fraction (LVEF)>40%, and had higher PTH [84.7 (59.6-104.7) vs 63.2 (49.2-85.2) pg/ml; p=0.007], galectin-3 [9.6 (8.0-11.1) vs 8.3 (6.9-9.9) ng/ml; p=0.037], and NGAL (208.5±87.6 vs 173.9±73.4 ng/ml; p=0.031) plasma levels than those without LVH. Glomerular filtration rate was lower in patients with LVH than in those without it (65.1±20.0 vs 74.7±19.9 mL/min/1.73 m2; p=0.021). There were no significant differences in hypertension (79.3 vs 68.4%; p=0.363) or sex between both groups. Variables showing differences based on univariate analysis and hypertension were entered into a logistic regression analysis. Only age [odds ratio (OR) =1.052 (1.011-1.096); p=0.013], PTH plasma levels [OR=1.017 (1.003-1.031); p=0.021], and LVEF>40% [OR=7.595 (1.463-39.429); p=0.016] were independent predictors of LVH. CONCLUSIONS: In patients with SCAD, elevated PTH levels are independently associated with the presence of LVH. Further studies are needed to elucidate the role of PTH in the development of myocardial hypertrophy.

The determination of copeptin levels helps management decisions among transient ischaemic attack patients.

BACKGROUND: Most approaches to transient ischaemic attack (TIA) triage use clinical scores and vascular imaging; however, some biomarkers have been suggested to improve the prognosis of TIA patients. METHODS: Serum levels of copeptin, adiponectin, neopterin, neuron-specific enolase, high-sensitivity C-reactive protein, IL-6, N-terminal pro-B-type natriuretic peptide, S100ß, tumour necrosis factor-alpha and IL-1α as well as clinical characteristics were assessed on consecutive TIA patients during the first 24 h of the onset of symptoms. RESULTS: Among 237 consecutive TIA patients, 12 patients (5%) had a stroke within 7 days and 15 (6%) within 90 days. Among all candidate biomarkers analysed, only copeptin was significantly increased in patients with stroke recurrence (SR) within 7 days (P = 0.026) but not within 90 days. A cut-off point of 13.8 pmol/l was established with a great predictive negative value (97.4%). Large artery atherosclerosis (LAA) [hazard ratio (HR) 12.7, 95% CI 3.2-50.1, P < 0.001] and copeptin levels ≥13.8 pmol/l (HR 3.9, 95% CI 1.01-14.4, P = 0.039) were independent predictors of SR at the 7-day follow-up. LAA was the only predictor of 90-day SR (HR 7.4, 95% CI 2.5-21.6, P < 0.001). ABCD3I was associated with 7- and 90-day SRs (P = 0.025 and P = 0.034, respectively). The association between copeptin levels and LAA had a diagnostic accuracy of 90.3%. CONCLUSIONS: Serum copeptin could be an important prognostic biomarker to guide management decisions among TIA patients. Therefore, TIA patients with copeptin levels below 13.8 pmol/l and without LAA have an insignificant risk of 7-day SR and could be managed on an outpatient basis.

The use of the acute Pd/Pa drop after intracoronary nitroglycerin infusion to rule out significant FFR: CANICA (Can intracoronary nitroglycerin predict fractional flow reserve without adenosine?) multicenter study.

OBJECTIVE: Functional assessment of coronary artery stenosis is performed by measuring the fractional flow reserve (FFR) under hyperemic conditions (Adenosine). However, the use of adenosine portends limitations. OBJECTIVE: We sought to investigate the relationship and correlation between FFR and the Pd/Pa value obtained just after the intracoronary infusion (acute drop) of nitroglycerin (Pd/Pa-NTG) and if this parameter enhances diagnostic accuracy for FFR prediction compared to the resting baseline Pd/Pa. METHODS: We conducted a multicenter study including prospectively patients presenting intermediate coronary artery stenosis (30-70%) evaluated with pressure wire. Resting baseline Pd/Pa, Pd/Pa-NTG and FFR were measured. RESULTS: 283 patients (335 lesions) were included. Resting baseline Pd/Pa value was 0.72 to 1.0 (0.93 ± 0.04), Pd/Pa-NTG was 0.60 to 1.0 (0.87 ± 0.07) and FFR 0.55 to 1.0 (0.83 ± 0.08). The ROC curves for resting baseline Pd/Pa and for Pd/Pa-NTG, using a FFR ≤ 0.80 showed an AUC of 0.88 (95% CI: 0.84-0.92, P < 0.001) and 0.94 (95% CI: 0.92-0.96, P < 0.001) respectively. The optimal cutoff values of resting baseline Pd/Pa and Pd/Pa-NTG for an FFR > 0.80, were >0.96 and >0.88, respectively. These values were present in a 29.8% (n = 100) and a 47.1% (n = 158), of the total lesions. Scatter plots showed a better correlation and agreement points with Pd/Pa-NTG than resting baseline Pd/Pa. The cutoff value of Pd/Pa-NTG > 0.88 showed an excellent NPV (96.2% for FFR > 0.8 and 100% for FFR > 0.75) and sensitivity (95% for FFR > 0.8 and 100% for FFR > 0.75) which were consistently high across all the subgroups analysis. CONCLUSION: The cutoff value of acute Pd/Pa-NTG > 0.88 has a high NPV meaning adenosine-FFR can be avoided in almost half of lesions.

Sex addiction and gambling disorder: similarities and differences.

OBJECTIVE: Recently, the DSM-5 has developed a new diagnostic category named "Substance-related and Addictive Disorders". This category includes gambling disorder (GD) as the sole behavioral addiction, but does not include sex addiction (SA). The aim of this study is to investigate whether SA should be classified more closely to other behavioral addictions, via a comparison of the personality characteristics and comorbid psychopathology of individuals with SA with those of individuals with GD, which comes under the category of addiction and related disorders. METHOD: The sample included 59 patients diagnosed with SA, who were compared to 2190 individuals diagnosed with GD and to 93 healthy controls. Assessment measures included the Diagnostic Questionnaire for Pathological Gambling, the South Oaks Gambling Screen, the Symptom CheckList-90 Items-Revised and the Temperament and Character Inventory-Revised. RESULTS: No statistically significant differences were found between the two clinical groups, except for socio-economic status. Although statistically significant differences were found between both clinical groups and controls for all scales on the SCL-90, no differences were found between the two clinical groups. The results were different for personality characteristics: logistic regression models showed that sex addictive behavior was predicted by a higher education level and by lower scores for TCI-R novelty-seeking, harm avoidance, persistence and self-transcendence. Being employed and lower scores in cooperativeness also tended to predict the presence of sex addiction. CONCLUSIONS: While SA and GD share some psychopathological and personality traits that are not present in healthy controls, there are also some diagnostic-specific characteristics that differentiate between the two clinical groups. These findings may help to increase our knowledge of phenotypes existing in behavioral addictions.

Cross-sectional anatomy, computed tomography and magnetic resonance imaging of the head of common dolphin (Delphinus delphis) and striped dolphin (Stenella coeruleoalba).

Computed tomography (CT) and low-field magnetic resonance imaging (MRI) were used to scan seven by-caught dolphin cadavers, belonging to two species: four common dolphins (Delphinus delphis) and three striped dolphins (Stenella coeruleoalba). CT and MRI were obtained with the animals in ventral recumbency. After the imaging procedures, six dolphins were frozen at -20°C and sliced in the same position they were examined. Not only CT and MRI scans, but also cross sections of the heads were obtained in three body planes: transverse (slices of 1 cm thickness) in three dolphins, sagittal (5 cm thickness) in two dolphins and dorsal (5 cm thickness) in two dolphins. Relevant anatomical structures were identified and labelled on each cross section, obtaining a comprehensive bi-dimensional topographical anatomy guide of the main features of the common and the striped dolphin head. Furthermore, the anatomical cross sections were compared with their corresponding CT and MRI images, allowing an imaging identification of most of the anatomical features. CT scans produced an excellent definition of the bony and air-filled structures, while MRI allowed us to successfully identify most of the soft tissue structures in the dolphin's head. This paper provides a detailed anatomical description of the head structures of common and striped dolphins and compares anatomical cross sections with CT and MRI scans, becoming a reference guide for the interpretation of imaging studies.
