Current status of robotic training during the urology residency: results from a national survey in Spain.

INTRODUCTION AND OBJECTIVES: The increasing number of robotic urological procedures observed in recent years highlights the need to expand training opportunities in robotic surgery. Our objective is to investigate the state of robotic training during urology residency in Spain in order to identify significant deficiencies. MATERIALS AND METHODS: A 20-item online survey was conducted among urology residents in Spain who were registered in the database of the Residents and Young Urologists Group of the Spanish Association of Urology. The survey assessed subjective opinions, institutional aspects, training resources, and experience regarding robotic surgery. A total of 455 email invitations were sent throughout the year 2021. Descriptive analysis of the responses was performed. RESULTS: The participation rate reached 30%, with a total of 135 residents. 52% of respondents lacked access to a robotic system in their institution, of which only 48% could compensate for this deficiency through external rotations. Among those with access to a robotic system, 25% and 23% reported having access to theoretical and practical training, respectively. The existence of a formal training program was low (13%). 85% of the respondents considered robotic surgery training in Spain to be deficient. CONCLUSIONS: Training for Spanish residents in robotic urological surgery is perceived as inadequate, emphasizing the crucial need for improvement in training programs in this field.

Clinical Usefulness of Prostate-specific Membrane Antigen-ligand Positron Emission Tomography/Computed Tomography for the Detection of Prostate Cancer Biochemical Recurrence after Primary Radiation Therapy in Patients with Prostate-specific Antigen Below the Phoenix Threshold: Systematic Review and Meta-analysis.

AIMS: After primary radiotherapy, biochemical recurrence is defined according to the Phoenix criteria as a prostate-specific antigen (PSA) value >2 ng/ml relative to the nadir. Several studies have shown that prostate-specific membrane antigen (PSMA)-ligand positron emission tomography/computed tomography (PET/CT) can help in detecting recurrence in patients with low PSA values. This study aimed to assess the detection rate and patterns of PSMA-ligand PET/CT uptake in patients with suspected biochemical recurrence after primary radiotherapy and with PSA levels below the Phoenix threshold. MATERIALS AND METHODS: The meta-analysis was carried out in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Articles providing data on patients with suspected prostate cancer recurrence after primary radiotherapy with a PSA value below the Phoenix threshold and who underwent PSMA-ligand PET/CT were included. Quality assessment was carried out using the Quality Assessment of Diagnostic Accuracy Studies-2 tool (QUADAS-2). RESULTS: In total, five studies were included, recruiting 909 patients (202 with PSA ≤2 ng/ml). The PSMA-ligand detection rate in the patients with ≤2 ng/ml ranged from 66 to 83%. The most frequent source of PSMA-ligand PET/CT uptake was local recurrence, followed by lymph node metastasis and bone metastasis. PSMA-ligand PET/CT uptake due to local-only recurrence was more likely in patients with PSA ≤2 ng/ml compared with PSA > 2 ng/ml: risk ratio 0.72 (95% confidence interval 0.58-0.89), P = 0.003. No significant differences were observed in the detection of PSMA-ligand uptake in other areas. Limitations include a lack of biopsy confirmation, cohort reports with small sample sizes and a potentially high risk of bias. CONCLUSION: A significant detection of PSMA-ligand-avid disease was observed in patients with PSA levels below the Phoenix threshold. There was a higher likelihood of detecting local-only uptake when the PSA value was ≤2 ng/ml. The findings suggest that a critical review of the Phoenix criteria may be warranted in the era of PSMA-ligand PET/CT and highlight the need for further prospective trials.

Attitudes scale toward cancer-related cognitive changes - an initial Colombian validation.

OBJECTIVE: The aim of this study was to develop an initial valid tool to measure attitudes toward cancer-related cognitive changes. SUBJECTS AND METHODS: After revising the literature, three main dimensions were hypothesized. Eight judges were contacted to obtain content validity evidence. A robust Exploratory Factor Analysis (EFA) was performed via a parallel analysis with an Unweighted Least Squares (ULS) estimator and polychoric correlations. The results were crossed with sociodemographic variables to find possible statistical differences and estimate the size effect. Analysis was performed in the software Factor and the statistical package R. RESULTS: A sample of 374 participants was obtained, involving oncology patients, their caregivers, and people from the general community. A statistical fit was found in two dimensions: Awareness and Judgments [root mean squared error of approximation (RMSEA) = 0.042, standardized root mean square residual (SRMR) = 0.02, comparative fit index (CFI) = 0.99, Tucker-Lewis index (TLI) = 0.98] with a moderate correlation between them (r = 0.612). Optimal reliability indices were obtained for the total scale and its dimensions. No real statistical difference was found between sociodemographic variables; the interpretation norms were established via the quartiles. CONCLUSIONS: The first attempt to measure the construct of interest was developed with two primary validity evidence based on the content and its internal structure. This instrument could help strengthen the prevention of cancer-related cognitive changes. More research is needed to adhere more valid evidence to the scale.

Impact of genetic diversity and antibiotic-resistance of Salmonella isolated from feral cats: One Health approach.

Free-living cats usually live in colonies in urban areas, especially close to parks and neighbourhoods where people feed them without any sanitary control. This can pose a human, animal and environmental health concern due to the close contact between uncontrolled colonies, the population and other domestic and/or wild animals. Thus, this study aimed to assess the genetic diversity and antimicrobial resistance (AMR) among Salmonella enterica subsp. enterica strains isolated from feral cats in a previous epidemiological study in the Gran Canaria island (Spain). A total of nineteen Salmonella isolates were obtained from November 2018 to January 2019 in a Salmonella epidemiological study in feral cats. All isolates obtained were genotyped by pulsed-field gel electrophoresis (PGFE) and were tested for antimicrobial susceptibility, in accordance with Decision 2013/652/EU. PFGE analysis revealed isolates clustering by serovar, with identical clones for serovars Bredeney and Grancanaria, while differing pulsotypes were observed for serovars Florida (88.89 % similarity) and Nima (83.23 % similarity). All but two isolates were resistant to at least one antimicrobial. The results obtained demonstrate that feral cats in the region investigated are a reservoir of Salmonella strains resistant to gentamicin (94.1 %) and of the critically important antimicrobial tigecycline (23.5 %). Hence, they could excrete AMR strains through their faeces and contaminate the environment, favoring the spread of such bacteria to cohabiting pets. Moreover, this widespread presence of AMR Salmonella clones across various serovars highlights the urgent need to implement efficient antimicrobial stewardship and control programs by the local governments due to the ongoing need to protect human and animal health under a One Health concept.

Impact of percutaneous cholecystostomy in the management of acute cholecystitis: a retrospective cohort study at a tertiary center.

Laparoscopic cholecystectomy is the gold standard for the treatment of acute cholecystitis (AC). Percutaneous cholecystostomy (PC) for management of AC is increasing; safe and less invasive than laparoscopic cholecystectomy and is very useful in selected patients with severe comorbidities, not suitable for surgery/general anesthesia. We conducted a retrospective observational study between 2016 and 2021 of patients treated with PC for AC, based on the application of the Tokyo guidelines 13/18. The aim was to analyse the clinical results and management of PC in patients undergoing elective or emergency cholecystectomy. Subsequently, a retrospective analytical study was designed to compare various cohorts: elective or emergency surgery and management with PC alone; patients with/without a high surgical risk; and elective vs emergency surgery. Hundred and ninety five patients with AC were treated with PC. Mean age was 74 years, 59.5% were ASA class III/IV, and the mean Charlson comorbidity index was 5.5. Adherence to Tokyo guidelines regarding indication of PC was 50.8%. The rate of complications associated to PC was 12.3% and the 90-day mortality rate was 14.4%. Mean length of time using PC was 10.7 days. Emergency surgery was performed in 4.6%. The overall success rate using PC was 66.7%, and the 1-year readmission rate due to biliary complications after PC was 28.2%. The rate of scheduled cholecystectomy after PC was 22.6%. Conversion to laparotomy and open approach was more frequent in patients who underwent emergency surgery (p = 0.009). No differences were found in 90-day mortality or in the complication rate. PC achieves improvements in the inflammation and infection associated with AC. In our series, it proved to be an effective and safe treatment during the acute episode of AC. Mortality in patients treated with PC is high due to their older age, greater morbidity, and higher Charlson comorbidity index scores. After PC, emergency surgery is uncommon but readmission due to biliary events is high. Cholecystectomy after PC is the definitive treatment and the laparoscopic approach is feasible. Clinical trial registery: The study was registered in the public accessible database clinicaltrials.gov with the ClinicalTrials.gov ID: NCT05153031. Public release date: 12/09/2021.

Visión global de la VMNI en las tres primeras olas de la COVID-19en la Comunidad de Madrid / Global vision of NIV during the first three waves of COVID-19 in the Community of Madrid

La neumonía COVID ha supuesto un reto para la Neumología que ha respondido de forma rápida y con resultados muy satisfactorios a la demanda de soporte ventilatorio no invasivo que esta enfermedad y sobre todo la sobrecarga en las Unidades de Cuidados Intensivos ha ocasionado. En el caso de la Comunidad Autónoma de Madrid (CAM), la mayoría de los centros hospitalarios ampliaron o implantaron los recursos que facilitaron el uso de esta terapia para miles de pacientes que de otro modo no hubieran tenido la oportunidad de mejorar su situación respiratoria. Mediante este artículo queremos dar a conocer la visión global de esta intervención en 14 centros de la red de hospitales de la CAM (AU)

COVID pneumonia has been a challenge for Pulmonology that has responded quickly and with very satisfactory results to the demand for non-invasive ventilatory support that this disease and especially the overload in Intensive Care Units has caused. In the case of the Autonomous Community of Madrid (CAM), most hospitals expanded or implemented the resources that facilitated the use of this therapy for thousands of patients who otherwise would not have had the opportunity to improve their respiratory situation. Through this article we want to present the global vision of this intervention in 14 centers of the CAM network of hospitals (AU)

Atención del paciente con EPOC mediante un programa de e-salud / E-health for copd patients

La e-salud, apoyada en el uso de las nuevas tecnologías, nos da las herramientas necesarias para innovar en la asistencia a nuestros pacientes y ha permitido evolucionar el concepto de la relación profesional sanitario-paciente. Sus aplicaciones son prácticamente ilimitadas y los estudios avalan su eficacia, si bien, existen una serie de cuestiones que limitan su implementación real (dificultad para la comparación metodológica, factores asociados al profesional o al paciente, aspectos éticos y legales, etc.). Una de las aplicaciones más interesantes desde el punto de vista clínico es la tele-consulta, especialmente en la actual situación de pandemia por la COVID-19. En este trabajo revisamos las posibilidades de implementación de un programa de tele-consultas en pacientes con EPOC, la selección de candidatos, las posibles herramientas tecnológicas y las limitaciones de este tipo de programas (AU)

E-health using new technologies is a new way to attend our patients and creates a new scenario in the relation between patients and their health carers. Their applications are uncontable and many articles support their efficacy, although some questions still make difficult its implementation. One of the most interesting applications for clinicians is teleconsultation, specially nowadays with COVID pandemic. We review the possible implementation of a tele-consultation program for COPD patients, the right selection of patients, technological tools and its limitations (AU)

Evaluation of health care-associated infections following radical cystectomy. / Estudio de las infecciones relacionadas con la asistencia sanitaria tras la realización de cistectomía radical.

INTRODUCTION AND OBJECTIVE: Radical cystectomy is a complex surgery with a high rate of complications including infections, which lead to increased morbidity and mortality, longer hospital stay and higher costs. The aim of this work is to evaluate health care-associated infections (HAIs) in these patients, as well as associated microorganisms, antibiotic resistance profiles and risk factors. MATERIAL AND METHODS: Prospective study from 2012 to 2017. Epidemiologic variables, comorbidities and surgical variables are collected. The microorganisms involved and antibiotic susceptibility patterns are analyzed. RESULTS: 122 patients. Mean age 67 (SD:18,42). Mean hospital stay 23.5 days (18.42). HAIs rate of 45%, with predominant urinary tract infections (43%) and surgical wound infections (31%). Positive cultures in 78.6% of cases. Increased isolation of Enterococcus (18%) and Escherichia coli (13%). Forty-three percent of microorganisms were resistant to amoxicillin/ampicillin, 23% to beta-lactamases and 36% to quinolones. Empirical treatment was adequate in 87.5%. Hospital stay is increased (17 days, p< 0.05) due to HAIs. Lower rate of infectious complications in the laparoscopic vs. open approach (p< 0.001) and in orthotopic vs. ileal conduit diversion (p = 0.04) CONCLUSIONS: We found a high rate of HAIs in our radical cystectomy series, with predominant urinary tract and surgical wound infections. E.coli and Enterococcus spp. are the most frequently isolated microorganisms, with high rates of resistance to some commonly used antibiotics.

Active unilateral condylar hyperplasia: Assessment of the usefulness of single photon emission computed tomography.

BACKGROUND: This study aims to evaluate whether the uptake difference by the condyles evaluated using single photon emission computed tomography (SPECT) examination is useful for predicting the activity of the feature and the advance of this pathology. MATERIAL AND METHODS: An observational and prospective study has been carried out on nine patients affected by unilateral condylar hyperplasia (UCH) with complete bone maturation, with a follow-up over 18 months. At the beginning of the study, a test-battery was conducted including dental casts, articular examination, teleradiography and cephalometry, computed tomography and SPECT, creating two groups of patients from a difference in uptake between both condyles greater than 10% over the follow-up period. Evolution of data obtained with the rest of the diagnostic tests were compared to confirm UCH activity predicted by SPECT. RESULTS: The comparison of both groups did not show hardly any significant differences, with little clinical significance. Deviation of the mandibular line, the size of the branches or condyles behaved similarly in both study groups. CONCLUSIONS: From the data obtained in our study, we can conclude that the use of the difference in uptake between both condyles by applying the SPECT technique is not a valid approach for predicting clinical activity in cases of UCH.

[Development of animal experimental model for bacterial peritonitis]. / Desarrollo de modelo experimental animal de peritonitis bacteriana.

OBJECTIVE: The aim of the study was to develop a model of abdominal sepsis in the experimental animal. METHODS: Sprague-Dawley male rats of 5 weeks (N=39) were used. Initially, a pilot study (N = 9) was performed and distributed in 3 groups with 1cc inoculum of Escherichia coli ATCC 25922 intraperitoneally at concentrations of 10E8, 10E9 and 10E10 CFU. Subsequently, concentrations of 10E10 CFU are used in two groups of 3 rats with dilutions of 10 cc and 15 cc of distilled water respectively. Finally, a randomized trial of 24 rats was started in three treatment groups after intraperitoneal infection: Group I with physiological serum (N = 6), Group II with ceftriaxone (N = 9), Group III with ceftriaxone plus allicin (N = 9). Microbiological samples of blood and peritoneal fluid were made, as well as histopathological study of intraperitoneal organs (liver, diaphragm and peritoneum). RESULTS: Death of 100% of the rats infected with 10E10 E. coli UFC concentration with the dilution of 15 ml of distilled water and without antibiotic was oberved. The blood culture and peritoneal fluid culture was positive for the same strain in all of them. The formation of abscesses on the liver surface and polymorphonuclear infiltration in tissues were observed. CONCLUSIONS: The lethal dose of E. coli is 10E10 CFU diluted in 15 cc distilled water by intraperitoneal injection.

Fármacos en investigación / Investigational drugs

La piedra angular del tratamiento de la enfermedad pulmonar obstructiva crónica (EPOC) es la broncodilatación, y en los últimos años se ha desarrollado un importante número de moléculas que han ido cambiando paulatinamente la práctica clínica habitual en estos pacientes. Los fármacos multivalentes con más de un mecanismo de acción broncodilatador representan el próximo paso en materia de relajación del músculo liso bronquial, pero dada la creciente evidencia sobre el estrés oxidativo y estado inflamatorio generalizado de la EPOC, existe una clara tendencia a demostrar el beneficio de formulaciones antiinflamatorias respecto a un potencial control sintomático, y secundariamente la reducción de la importante carga económica que supone el consumo de recursos sanitarios. En este capítulo se pretende dar un resumen esquemático y actualizado sobre los fármacos en investigación en EPOC en las fases previas de su desarrollo clínico

Bronchodilators are the cornerstone of Chronic obstructive pulmonary disease (COPD) treatment, and in the last years an important number of new molecules have changed gradually the clinical practice in these patients. Multivalent drugs with more than one mechanism of action represent the next step in terms of bronchial smooth muscle relaxation, although, giving the growing evidence of oxidative stress and generalized inflammation in COPD, there is a clear tendency to test the potential benefit of new anti-inflammatory drugs for symptoms control in the first place and consequently the reduction of the high economic burden of this disease. This chapter aims to give a schematical and updated review of new drugs for COPD in the preclinical phases of their clinical development

Síndrome de apnea e hipopnea del sueño y cáncer / Obstructive sleep apnea and cáncer

Recientemente se ha vinculado al Síndrome de apnea e hipopnea del sueño (SAHS) con la incidencia y mortalidad por cáncer, aunque la literatura epidemiológica al respecto no es concluyente. A partir de modelos animales y algunos estudios en humanos sobre todo en pacientes con melanoma, se ha propuesto que la hipoxia intermitente y la fragmentación del sueño propias del SAHS constituyen el sustrato fisiopatológico de su relación con el cáncer, y al parecer el punto clave es la regulación del sistema inmune defensor de células con potencial oncogénico. La presente revisión pretende resumir una actualización en este campo dada la cantidad ingente de estudios publicados en los últimos años, con la propuesta de futuras líneas de investigación para mejorar la atención de los pacientes que acuden a las Unidades de Sueño

Recently, obstructive sleep apnea (OSA) has been related to cancer incidence and mortality, though epidemiological studies are not conclusive on the matter. Out of basic research and some studies in humans specially of patients with melanoma, it has been proposed that intermittent hypoxia and sleep fragmentation, hallmarks of OSA, are the main physiopathological factors in this relationship, and immune regulation against potentially oncogenic cells appears to be the key point of the effect of OSA on cancer. This review aims to present an updated revision highlighting future research areas in order to improve the medical care of OSA patients

Infections related to healthcare in patients hospitalized in a Urology service: resistance patterns and adequacy of empirical antibiotic treatment as a prognostic factor. / Infecciones relacionadas con la asistencia sanitaria en pacientes ingresados en un servicio de Urología: patrones de resistencia y adecuación del tratamiento antibiótico empírico como factor pronóstico.

OBJECTIVES: To evaluate the suitability of empirical antibiotic therapy in HAIs and the antibiotic resistance patterns of the responsible microorganisms, as well as the incidence of mortality and risk factors involved. METHOD: A prospective observational study was carried out on patients of both sexes older than 16years, admitted by any urological process during a period of 4years. The incidence and characteristics of HAIs, as well as the causative organism and its resistance, the initial empirical antibiotic therapy and its modification, if required, and mortality rates are analysed. RESULTS: Out of 6,546 patients, 6.3% suffered HAIs, 70.5% corresponding to urinary tract infection and 22.1% to infection of the surgical wound. E.coli, Enterococcus spp., Klebsiella spp. y P.aeruginosa were the most frequently implicated (25.1%, 17.5%, 13.5% and 12.3%, respectively). E.coli and Klebsiella spp. were producers of extended-spectrum beta-lactamases (ESBL) in 24.7% and 47.8%, respectively. 4.3% of Klebsiella and 33.3% of Pseudomonas were carbapenems-resistant. The overall resistance to quinolones was approximately 50%. The most commonly used antibiotics for empirical therapy were cephalosporins of 3rd and 4th generation (33.6%) and carbapenems (28.2%). An overall rate of adequacy of empirical antibiotic therapy of 82.9% was obtained. The mortality rate in patients with HAIs was 2.2%, compared with 0.3% in patients without infection. In a multivariate analysis, the variables associated with the highest mortality risk were the isolation of ESBL-producing enterobacteria and the inadequate empirical antibiotic treatment. CONCLUSIONS: The selection of empirical antibiotic therapy was quite accurate. An increase in HAIs by multiresistant microorganisms, such as ESBL Enterobacteria or multiresistant P.aeruginosa is being observed. The mortality risk increases with inadequate initial empirical antibiotic therapy or when the responsible microorganism is an ESBL enterobacteria.

Estado de la ventilación mecánica en la Comunidad de Madrid / Home mechanical ventilation in Madrid area

Introducción. En la actualidad, la ventilación mecánica domiciliaria (VMD) se ha convertido en una terapia de uso habitual. La tasa de uso en España es desconocida, por lo que se ha realizado una encuesta en todos los hospitales de la Comunidad de Madrid (CAM) adscritos al Sistema Nacional de Salud para recoger los datos de los pacientes tratados con VMD en octubre y noviembre de 2018. Material y métodos. Se distribuyó una encuesta on-line entre todos los hospitales de la CAM de los grupos funcionales homogéneos (GFH) 1, 2 y 3 pertenecientes al Sistema Nacional de Salud. La encuesta constaba de 50 preguntas y se solicitó que se respondiera a las preguntas con datos reales, no estimados. Resultados. La encuesta la contestaron 18 hospitales, aunque todas las preguntas del cuestionario solo fueron contestadas por 10. La tasa de uso de VMD en la CAM fue de 74/100.000 habitantes. La edad media de los pacientes en VMD era de 69 años (63-76) y el 56% eran varones. La patología que más frecuentemente justificaba la VMD fue el síndrome de obesidad hipoventilación 41% (25-70). Se encontró mucha variabilidad intercentro tanto en la tasa de VMD como en la patología que justificaba la indicación. Todos los hospitales menos 2 disponían de consulta monográfica de VMD. La adaptación se realizaba fundamentalmente en hospitalización (33%) u hospital de día (33%). Se necesita más tiempo, más personal y mejores recursos técnicos para realizar una adecuada monitorización. La relación con las empresas suministradoras de terapias es buena

Introduction. Nowadays home mechanical ventilation (HMV) is a normal use in pneumology. Rate of use in Spain is unknown. We have developed a survey in all Public Madrid Area Hospitals to keep data about HMV patients between 2018 october and november. Methods. We sent an on-line survey to all Public Madrid Area Hospitals with 50 questions about HMV uses. We asked for real data answers, trying to not estimate answers. Results. The survey was answered by 18 hospitals, although all survey questions were answered by 10 hospitals. Rate of use of HMV in Madrid Area was 74/100.000. Mean age was 69 (63-76) years and 56% were males. The most frequent pathology that justified HMV was obesity hipoventilation syndrome 41% (25-70). We found a high variability interhospital in HMV rate and in the pathology that justified it. All the hospitals instead 2 of them had a monography HMV consult. HMV adaptation was done majority in hospitalization (33%) and in day hospital (33%). It is necessary more time, more people and better devices to achieve a proper monitoring. The relationship with the therapy providers is good

Motivos para seguir fumando en pacientes ingresados en un Servicio de Neumología / Reasons to continue smoking in patients admitted to the Pneumology Department

Objetivos. Conocer los motivos por los que los pacientes ingresados en neumología continúan fumando, y describir las características de fumadores, exfumadores y no fumadores. Métodos. Estudio observacional de corte transversal de 6 meses de duración. Se entregó una encuesta anónima y voluntaria a todos los pacientes ingresados en hospitalización. Resultados. Fueron incluidos un total de 284 pacientes, de los cuales 57 (20,1%) eran fumadores, 125 (44%) exfumadores y 102 (35,9%) no habían fumado nunca. Entre los fumadores hombres (37), el motivo más frecuente por el que fumaban fue ‘Placer-relajación’ (78,38%), mientras que entre las fumadoras mujeres (20) fue ‘Reducción de estados negativos’ (90%). Los exfumadores (125) dejaron de fumar en su mayoría por ‘Progresión de su enfermedad’ (50,4%). Los exfumadores presentaban una mayor frecuencia de hipertensión arterial, cardiopatía, enfermedad pulmonar obstructiva crónica (EPOC) y neoplasias que los fumadores, y mayor frecuencia de cardiopatías, EPOC y neoplasias que en aquellos que nunca habían fumado. El riesgo de padecer EPOC fue mayor en fumadores al compararlo con los que nunca habían fumado. Las mujeres comenzaron a fumar más tarde con una tasa de tabaquismo acumulado menor que los hombres. Una mayor edad se mostró como un predictor positivo de abandono. Conclusiones. Un 20,1% de los pacientes fumaba en el momento del ingreso. Continúan fumando por placer-relajación, adicción y reducción de estados negativos. Se ha encontrado en exfumadores una mayor frecuencia de diversas patologías, siendo la EPOC más frecuente en fumadores. Mayor edad se mostró como predictor positivo de abandono (AU)

Objectives. Determine the reasons why respiratory inpatients continue to smoke and describe the characteristics of smokers, former smokers and people who have never smoked. Methods. It was a 6-month observational, transversal study. A questionnaire was given to every patient admitted in the respiratory department. Results. 284 patients were included in the study, of which 57 (20.1%) were smokers, 125 (44%) former smokers and 102 (35.9%) had never smoked. Amongst the smoker men (37), the most frequent reason to continue smoking was ‘Pleasurable relaxation’ (78.38%), while in smoker women (20) it was ‘Tension reduction’ (90%). Former smokers (125) quitted the habit due to ‘Progression of their disease’ (50.4%). Former smokers had a greater frequency of developing hypertension, heart disease, chronic obstructive pulmonary disease (COPD) and cancer than those who had never smoked. The risk of having COPD was greater in smokers compared to those who had never smoked. Women began smoking later with a lower accumulated smoking rate than men. An older age was shown to be a positive predictor of abandon. Conclusions. A 20.1% of patients were reported as smokers at the time of admission. In general they continue smoking due to relaxation and pleasure, addiction and tension reduction. Different types of pathologies were found more frequently in former smokers, although COPD was more frequent in smokers. An older age was shown to be a positive predictor of abandon (AU)

The effect of crack cocaine addiction and age on the microstructure and morphology of the human striatum and thalamus using shape analysis and fast diffusion kurtosis imaging.

The striatum and thalamus are subcortical structures intimately involved in addiction. The morphology and microstructure of these have been studied in murine models of cocaine addiction (CA), showing an effect of drug use, but also chronological age in morphology. Human studies using non-invasive magnetic resonance imaging (MRI) have shown inconsistencies in volume changes, and have also shown an age effect. In this exploratory study, we used MRI-based volumetric and novel shape analysis, as well as a novel fast diffusion kurtosis imaging sequence to study the morphology and microstructure of striatum and thalamus in crack CA compared to matched healthy controls (HCs), while investigating the effect of age and years of cocaine consumption. We did not find significant differences in volume and mean kurtosis (MKT) between groups. However, we found significant contraction of nucleus accumbens in CA compared to HCs. We also found significant age-related changes in volume and MKT of CA in striatum and thalamus that are different to those seen in normal aging. Interestingly, we found different effects and contributions of age and years of consumption in volume, displacement and MKT changes, suggesting that each measure provides different but complementing information about morphological brain changes, and that not all changes are related to the toxicity or the addiction to the drug. Our findings suggest that the use of finer methods and sequences provides complementing information about morphological and microstructural changes in CA, and that brain alterations in CA are related cocaine use and age differently.
