Impact of Pleural Lavage Cytology Positivity on Early Recurrence After Surgery for Non-Small Cell Lung Cancer.

OBJECTIVE: The aim of this study was to elucidate the impact of pleural lavage cytology positivity on early recurrence in patients operated on non-small cell lung cancer (NSCLC). METHODS: This is a multicentre prospective cohort study of 684 patients undergoing an anatomical lung resection for NSCLC between October 2015 and October 2017 at 12 national centres. A pleural lavage was performed before and after lung resection. The association between the different predictors of early recurrence and PLC positivity was performed using univariate and multivariate logistic regression models. A propensity score analysis was performed by inverse probability weighting (IPSW) using average treatment effect (ATE) estimation to analyse the impact of PLC positivity on early recurrence. RESULTS: Overall PLC positivity was observed in 15 patients (2.2%). After two years, 193 patients (28.2%) relapsed, 182 (27.2%) with a negative PLC and 11 (73.3%) with a positive PLC (p<0.001). Factors associated to early recurrence were adenocarcinoma histology (OR=1.59, 95%CI 1.06-2.38, p=0.025), visceral pleural invasion (OR=1.59, 95%CI 1.04-2.4, p=0.03), lymph node involvement (OR=1.84, 95%CI 1.14-2.96, p=0.013), advanced pathological stage (OR=2.12, 95%CI 1.27-3.54, p=0.004) and PLC positivity (OR=4.14, 95%CI 1.25-16.36, p=0.028). After IPSW, PLC positivity was associated with an increased risk of early recurrence (OR=3.46, 95%CI 2.25-5.36, p<0.001). CONCLUSIONS: Positive pleural lavage cytology was found to be the strongest predictor of early recurrence.

[Surgical management of primary spontaneous pneumothorax. A national survey of the Emerging Thoracic Surgery Group of the Spanish Society of Pneumology and Thoracic Surgery (SEPAR)]. / Manejo quirúrgico del neumotórax espontáneo primario. Encuesta nacional del Grupo Emergente de Cirugía Torácica de la Sociedad Española de Neumología y Cirugía Torácica (SEPAR).

Introduction: In February 2022, the Emerging Thoracic Surgery Group of the Spanish Society of Pneumology and Thoracic Surgery initiated a multicenter study on the surgical management of primary spontaneous pneumothorax (PSP). As a preliminary step, this survey was developed with the aim of finding out the current situation in our country to specify and direct this project. Method: A descriptive study was carried out based on the results of this survey launched through the Google Docs® platform. The survey was sent to all active national thoracic surgeons, a total of 319. It consisted of 20 questions including demographic, surgical and follow-up data. Results: We obtained 124 responses (39% of all specialists and doctors in training in the national territory). The most consistent indications were: homolateral recurrence for 124 (100%), lack of resolution of the episode for 120 (96.7%), risk professions for 104 (84%) and bilateral pneumothorax for 93 (75%). The approach of choice for 100% of respondents was videothoracoscopy. Of these, 96 contemplated pulmonary resection of obvious lesions (77%). Regarding the pleurodesis technique, pleural abrasion was the technique most used by 70 respondents (56.7%) while 49 (40%) performed chemical pleurodesis with talc either alone or in combination with mechanical pleurodesis. Conclusions: While there is some consistency in some aspects of surgical management of PSP, this survey makes evident the variability in pleurodesis techniques applied among surgeons in our country.

Effects of diaphragm muscle treatment in shoulder pain and mobility in subjects with rotator cuff injuries: A dataset derived from a pilot clinical trial.

The rotator cuff inflammatory or degenerative pathology is the main cause of shoulder pain. The shoulder and diaphragm muscle have a clear relation through innervation and the connection through myofascial tissue. A prospective, randomized, controlled, single-blind (assessor) pilot clinical trial was performed with a sample size of 27 subjects with rotator cuff injuries and with clinical diagnosis of myofascial pain syndrome at shoulder. The sample were divided into 3 groups of treatment (9 subjects per group):1.A direct treatment over the shoulder by ischemic compression of myofascial trigger points (MTP) (control / rotator cuff group).2.Diaphragm manual therapy techniques (diaphragm group).3.Active diaphragm mobilization by breathing exercises (breathing exercises group).The pain and range of shoulder motion were assessed before and after treatment in all the participants by inclinometry, NRS of pain in shoulder movements and pressure algometry. Methodology and full data analyzing the effect of the three interventions are presented in this article. These data could give a basis for further experiments on revealing the underlying mechanism of action of the visceral manual therapy in reducing the symptoms of shoulder pain.

There were 14 false negative cases (4.6%) and 36 false positive cases (11.8%). CONCLUSIONS: Age, SUVmax, previous malignant disease, and female sex were independent risk factors in our study. Each case should be individually evaluated in a multidisciplinary committee, and the patient's preferences or concerns should be kept in mind in decision-making. Surgical resection of PSN is not exempt from morbidity and mortality, even in sublobar or pulmonary wedge resection.

VIH y tabaco / HIV and tobacco

El virus de la inmunodeficiencia humana (VIH) se considera una enfermedad crónica tras la introducción de la terapia antirretroviral (TAR). Se ha reportado que las personas con VIH tienen una alta prevalencia de tabaquismo, fuman en mayor cantidad y con niveles más altos de dependencia. El mayor problema radica en que estos pacientes tienen una mayor susceptibilidad al tabaco, desarrollando enfermedades cardiacas o cáncer en edades más tempranas y con un menor consumo acumulado. Además, también provoca alteraciones en la respuesta al TAR, ocasionando una probabilidad menor de lograr la supresión viral y una mayor de fallo inmunológico en pacientes fumadores. Por todo ello, disminuir la morbilidad y mortalidad en esta población abordando el tratamiento del tabaquismo debería ser una prioridad. Las intervenciones combinadas de tratamiento farmacológico y terapia cognitivo conductual parecen ser eficaces y seguras. Sin embargo, sería imprescindible plantear estudios futuros que incluyan las características especiales de esta población para poder obtener resultados concluyente

The human immunodeficiency virus (HIV) is considered a chronic disease after the introduction of antiretroviral therapy (ART). It has been reported that people with HIV have a higher prevalence of smoking, smoke more number of cigarettes and have higher levels of dependence. The biggest problem is that these patients have a greater susceptibility to tobacco. In this group of patients, this situation strongly relates to comorbidities, such as heart disease or different types of cancer which develop at younger ages and all of this with a lower cumulative consumption. Furthermore, smoking also causes alterations in the response to ART, causing a lower probability of achieving viral suppression and a greater probability of immune failure in smokers. Therefore, reducing morbidity and mortality in this population using smoking cessation interventions should be a priority. The combined interventions of pharmacological treatment and cognitive therapy seem to be effective and safe. However, it would be essential to propose future studies in order to determine the special characteristics of this population with the objective to obtain conclusive results

Diferencias entre los fumadores que no inician el tratamiento y los que sí lo inician / Differences between smokers who do not begin the treatment and those who do

Introducción: De los pacientes que acuden a la consulta a dejar de fumar, muchos no vuelven a la segunda consulta, por lo que no inician el tratamiento. Objetivo: Se intentaron determinar las características diferenciales de esta población respecto a los pacientes que sí iniciaron tratamiento. Pacientes y métodos: 1.484 pacientes acudieron a la Unidad de Tratamiento Especializado en Tabaquismo del Complejo Hospitalario Universitario de Albacete desde el 1 de enero de 2008 hasta el 31 de diciembre de 2012. Se utilizaron la Chi-cuadrado y la prueba exacta de Fisher para variables cualitativas y t de Student para cuantitativas y se realizó una regresión logística para evitar variables confusoras. El nivel de significación se estableció con una p < 0,05. Resultados: Se incluyeron en el estudio un total de 1.484 pacientes, de ellos, 731 sujetos abandonan el tratamiento sin acudir a la segunda consulta, esto es un 49,26% del total. En el modelo de regresión logística que se hizo no se observó que ninguna variable influyera de forma significativa. Conclusión: Hay muchos pacientes que, a pesar de acudir a una primera cita, no continúan con el tratamiento. Esto supone un fracaso que debemos estudiar

Introduction: Many of the patients who come to the consultation to stop smoking do not return to the second visit, so they do not initiate treatment. Objective: An attempt was made to determine the differential characteristics of the latter population regarding the patients who did initiate treatment. Patients and methods: 1484 patients came to the Smoking Habit Specialized Treatment Unit of the Complejo Hospitalario Universitario of Albacete from 1 January 2008 to 31 December 2012. The Chi-squared and the Fisher exact test were used for qualitative variables and the Student T test for quantitative variables and a logistic regression was performed to avoid confounding variables. Significance level was established with a p < 0.05. Results: A total of 1484 patients were included in the study. Of these, 731 abandoned treatment wihout coming to the second visit, this accounting for 49.26% of the total. It was not observed that any variable significantly affected the result in the logistic regressions model made. Conclusion: There are many patients who, in spite of coming to the first visit, do not continue with the treatment. This supposes a failure we need to study

Is video-assisted thoracoscopic diaphragmatic plication a widespread technique for diaphragmatic hernia in adults? Review of the literature and results of a national survey.

Diaphragmatic plication is the most accepted treatment for symptomatic diaphragmatic hernia in adults. The fact that this pathology is infrequent and this procedure not been widespread means that this is an exceptional technique in our field. To estimate its use in the literature, we carried out a review in English and Spanish, to which we added our series. We found only six series that contribute 59 video-assisted mini-thoractomy for diaphragmatic plications in adults, and none in Spanish. Our series will be the second largest with 18 cases. Finally, we conducted a survey in all the Spanish Thoracic Surgery units in Spain: none reported more than 10 cases operated by thoracoscopy in the last 8 years (except our series) and most continue employing thoracotomy as the main approach. We believe that many patients with symptomatic diaphragmatic hernia could benefit from the use of such techniques.

Influencia pronóstica de la pérdida de la expresión del antígeno del grupo sanguíneo A en el carcinoma no microcítico de pulmón en estadio I patológico / Prognostic Influence of Loss of Blood Group A Antigen Expression in Pathologic Stage I Non-Small-Cell Lung Cancer

Introducción: En la literatura científica se han publicado resultados contradictorios sobre el valor pronóstico de la pérdida de la expresión del antígeno de grupo sanguíneo A (GSA) en el cáncer de pulmón, por lo que analizamos retrospectivamente este hecho en nuestra serie quirúrgica. Pacientes y métodos. En un estudio multicéntrico de 402 pacientes con carcinoma no microcítico de pulmón (CNMP) en estadio I patológico según la nueva clasificación TNM-2009 se analizó la influencia pronóstica de la pérdida de la expresión del antígeno del GSA en los 209 pacientes con grupos sanguíneos A o AB. Resultados: La supervivencia a los 5 años de los pacientes en estadio I patológico que mantenían la expresión del antígeno del GSA fue del 73%, frente a una supervivencia del 53% en los pacientes que habían perdido la expresión del mismo (p=0,03). Cuando se analizó la supervivencia subdividiendo la muestra en estadios IA y IB, solo se alcanzó la significación estadística en el estadio IA (p=0,038). Al analizar la supervivencia según el tipo histológico, los pacientes con adenocarcinoma que perdían la expresión del antígeno del GSA tenían una menor supervivencia, con una p estadísticamente muy significativa (p=0,003). El análisis multivariable mostró que la edad, el género y la expresión del antígeno del GSA eran factores pronósticos independientes. Conclusiones: La pérdida de la expresión del antígeno del grupo sanguíneo A tiene una influencia pronóstica negativa en el CNMP estadio I patológico, sobre todo en el tipo histológico adenocarcinoma(AU)

Introduction: In the scientific literature, contradictory results has been published on the prognostic value of the loss of expression of blood group antigen A (BAA) in lung cancer. The objective of our study was to analyze this fact in our surgical series. Patients and methods: In a multicenter study, 402 non-small-cell lung cancer (NSCLC) patients were included. All were classified as stage-I according to the last 2009-TNM classification. We analyzed the prognostic influence of the loss of expression of BAA in the 209 patients expressing blood group A or AB. Results: The 5-year cumulative survival was 73% for patients expressing BAA vs 53% for patients with loss of expression (P=.03). When patients were grouped into stages IA and IB, statistical significance was only observed in stage I-A (P=.038). When we analyzed the survival according to histologic type, those patients with adenocarcinoma and loss of expression of BAA had a lower survival rate that was statistically very significant (P=.003). The multivariate analysis showed that age, gender and expression of BAA were independent prognostic factors. Conclusions: The loss of expression of blood group antigen A has a negative prognostic impact in stage I NSCLC, especially in patients with adenocarcinoma(AU)
