RESUMO
INTRODUCTION: The smoker's narrative during smoking quitting provides insight into aspects not fully explored in daily clinical practice. The aim of the study was to analyze the smoker narrative using two types of methodologies: content analysis and grounded theory, before and after smoking cessation intervention, provided to the smoker in a specialized Smoking Cessation Unit accredited by the Spanish Society of Pneumology and Thoracic Surgery. METHODS: A prospective observational study of current smokers included in a tobacco cessation program between 2017 and 2020 was conducted at the Smoking Cessation Unit of Santiago de Compostela Health Area, Spain. Routine clinical variables and patient narrative data were collected. A descriptive analysis of the sample, the content of the textual corpus, and a grounded theory were performed in semi-structured interviews at baseline and at follow-up at 6 months. RESULTS: A total of 116 patients were included (mean age 55.6 ± 10.6 years; 56.9% male; mean nicotine dependence score 5.7 ± 1.6). Quantitative analysis of the narrative shows that the most frequent phrases and words are associated with smoking, nicotine craving, and predisposition for smoking cessation. After the intervention, phrases related to the manifestation of abstinence, response to pharmacological treatment, and self-perception of smoking cessation were predominant. In the qualitative analysis, the most frequent categories in the smoker's textual corpus were dependence, motivation, and emotionality, which decreased after the intervention (11.4%, 21.4%, and 9.9%, respectively) accompanied by increased satisfaction (19.2%) and the manifestation of abstinence (21.5%). CONCLUSIONS: Motivation, nicotine dependence, and sensitivity to emotions are all closely intertwined in the current smoker narrative and can be modified as a consequence of treatment.
RESUMO
BACKGROUND: Although pulmonary rehabilitation (PR) is recommended in patients with chronic obstructive pulmonary disease (COPD), there is a scarcity of data demonstrating the cost-effectiveness and effectiveness of PR in reducing exacerbations. METHODS: A quasi-experimental study in 200 patients with COPD was conducted to determine the number of exacerbations 1 year before and after their participation in a PR program. Quality of life was measured using the COPD assessment test and EuroQol-5D. The costs of the program and exacerbations were assessed the year before and after participation in the PR program. The incremental cost-effectiveness ratio (ICER) was estimated in terms of quality-adjusted life years (QALYs). RESULTS: The number of admissions, length of hospital stay, and admissions to the emergency department decreased after participation in the PR program by 48.2%, 46.6%, and 42.5%, respectively (P < 0.001 for all). Results on quality of life tests improved significantly (P < 0.001 for the two tests). The cost of PR per patient and the cost of pre-PR and post-PR exacerbations were 1867.7 and 7895.2 and 4201.9, respectively. The PR resulted in a cost saving of 1826 (total, 365,200) per patient/year, and the gain in QALYs was+0.107. ICER was -17,056. The total cost was <20,000/QALY in 78% of patients. CONCLUSIONS: PR contributes to reducing the number of exacerbations in patients with COPD, thereby slowing clinical deterioration. In addition, it is cost-effective in terms of QALYs.
RESUMO
Introduction: Recently, contrast-enhanced mammography (CEM) has emerged as a reliable alternative to breast magnetic resonance imaging (MRI) for the assessment of pathological response in breast cancer patients. Our study sought to determine the diagnostic accuracy of CEM to predict pathological complete response (pCR) in patients who received neoadjuvant chemotherapy (NACT). Methods: We retrieved the medical records of patients who underwent NACT at our institution. Using post-surgery pCR, morphological evidence and CEM enhancement tumours were classified as follows: 1) radiologic complete response (rCR); 2) functional radiological complete response (frCR); and 3) non-complete response. Initially, we used multivariate analyses adjusted by clinical variables and frCR or rCR to determine which variables affected pathological response. Then, CEM diagnostic accuracy to discriminate pCR was assessed using receiver operating characteristic curves in univariate and multivariate models including either frCR or rCR. Results: A total of 48 patients were included in our study. Most patients (68.7%) were hormone receptor (HR)+ and 41.6% (20) of the patients achieved pCR. Using univariate logistic regression analyses we found that HR status, HER2 status, rCR and frCR had a significant impact on CEM diagnostic accuracy. Exploratory analyses found that CEM sensitivity was higher for HR- tumours. Multivariate logistic regression analyses found 60% sensitivity, 92.9% specificity and 79.2% accuracy in a model that included clinical variables and rCR. Conclusion: CEM is a reliable alternative to high-cost, time-consuming breast MRI that predicts pCR in patients undergoing NACT; CEM diagnostic accuracy was higher among patients who harboured HR- tumours.
RESUMO
OBJECTIVE: Currently in developed countries there is an increase in the consumption of roll your own tobacco, which is associated with a higher proportion of users of this form of tobacco who wish to make an attempt to quit. The objective of this study was to analyze the effectiveness of tobacco cessation interventions based on the type of tobacco consumed. METHODS: Longitudinal study of a cohort of 641 smokers recruited between 2015 and 2018 in a health area of Galicia included in smoking cessation programs, based on psychological counseling and pharmacological treatment. The characteristics and success of the intervention were evaluated in two groups: roll your own tobacco smokers (RYO) and manufactured tobacco smokers (MT). A logistic regression was performed to determine the probability of success in smoking cessation. The risk measure was the odds ratio (OR) with its 95% confidence interval. RESULTS: RYO users started at a younger age and had a lower sociocultural stratum than MT users. Interventions to quit smoking in RYO users were associated with less abstinence at 4 weeks (52% MT vs 38% LT) (OR: 0.5; 95% CI 0.35-0.99; p=0.045;) and at 3 months (42% TM vs 30% TL) (OR:0.6; 95% CI 0.33-0.98; p=0.04). CONCLUSIONS: Smoking cessation programs are less effective in short-term RYO users. There are no differences in long-term abstinence between the two groups.
OBJETIVO: Actualmente en los países desarrollados existe un aumento del consumo de tabaco de liar lo que se asocia a una mayor proporción de usuarios de esta forma de tabaco que desean realizar un intento de abandono. El objetivo de este estudio fue analizar la efectividad de las intervenciones de cesación tabáquica en función del tipo de tabaco consumido. METODOS: Estudio longitudinal de una cohorte de 641 fumadores reclutados entre 2015 y 2018 en un área sanitaria de Galicia incluidos en programas de deshabituación tabáquica, basados en el asesoramiento psicológico y en el tratamiento farmacológico. Se evaluaron las características y el éxito de la intervención en dos grupos: fumadores de tabaco de liar (TL) y fumadores de tabaco manufacturado (TM). Se realizó una regresión logística para determinar la probabilidad de éxito en la cesación tabáquica. La medida de riesgo fue el odds ratio (OR) con su intervalo de confianza al 95%. RESULTADOS: Los consumidores de TL se iniciaron a una edad más temprana y tenían un estrato sociocultural más bajo que los consumidores de TM. Las intervenciones para abandonar el tabaco en los consumidores de TL se asociaron a una menor abstinencia a las 4 semanas (52%TM vs 38% TL) (OR: 0,5; 95%IC 0,35-0,99; p=0,045;) y a los 3 meses (42%TM vs 30%TL) (OR:0,6; 95%IC 0,33-0,98; p=0,04). CONCLUSIONES: Los programas de cesación tabáquica son menos efectivas en los consumidores de TL a corto plazo. No se observan diferencias en la abstinencia a largo plazo entre ambos grupos.

PURPOSE: The implementation of national breast cancer (BC) screening programs in Latin America has been rather inconsistent. Instead, most countries have opted for "opportunistic" mammogram screenings on the population at risk. Our study assessed and compared epidemiological, clinical factors, and survival rates associated with BC detected by screening (SDBC) or self-detected/symptomatic (non-SDBC) in Chilean female patients. METHODS: Registry-based cohort study that included non-metastatic BC (stage I/II/III) patients diagnosed between 1993 and 2020, from a public hospital (PH) and a private university cancer center (PC). Epidemiological and clinical data were obtained from medical records. RESULTS: A total of 4559 patients were included. Most patients (55%; n = 2507) came from PH and were diagnosed by signs/symptoms (non-SDBC; n = 3132, 68.6%); these patients displayed poorer overall (OS) and invasive disease-free survival (iDFS) compared to SDBC. Importantly, the proportion of stage I and "luminal" BC (HR + /HER2 -) were significantly higher in SDBC vs. non-SDBC. Finally, using a stage/subset-stratified age/insurance-adjusted model, we found that non-SDBC cases are at a higher risk of death (HR:1.75; p < 0.001). In contrast, patients with PC health insurance have a lower risk of death (HR: 0.60; p < 0.001). CONCLUSION: We confirm previous studies that report better prognosis/survival on SDBC patients. This is probably due to a higher proportion of stage I and luminal-A cases versus non-SDBC. In turn, the survival benefit observed in patients with PC health insurance might be attributed to a larger proportion of SDBC. Our data support the implementation of a systematic BC screening program in Chile to improve patient prognosis and survival rates.

Red mud (RM) is an industrial waste of the aluminum industry with presently estimated worldwide legacy-site stockpiles of 4 billion tones. RM is typically disposed in the sea, dams or dykes, posing a significant environmental hazard due to its high alkalinity and traces of heavy metals. Despite recent valorization efforts, only 15% of RM deposits are currently utilized. In this work, a novel use of RM to formulate composite phase change materials (CPCMs) is proposed. The CPCM is formulated by milling nitrate salts with RM, compressing and subsequent sintering of the two. Overall good performance over the temperature range of 25-400 â is observed. Maximum latent heat of the CPCMs is 58 J/g, while average thermal conductivity and Cp are in the range of 0.77-0.83 W/mK and 1.03-1.31 J/g â, respectively. No variations in the melting point or latent heat are observed after 48 cycles. Energy storage density is calculated to be up to 1396 MJ/m3. The working temperature of this novel CPCM make it ideal for waste heat recovery of medium-high temperature waste heat streams providing a valorization pathway and valorization for RM as a by-product for energy-related applications.
RESUMO
ABSTRACT Background: About 80% of breast cancer (BC) cases express estrogen receptor (ER), which has been correlated with good prognosis and response to estrogen deprivation Aim: To characterize ER positive advanced BC (ABC) patients treated at our institution assessing the impact of clinical pre-sentation (stage IV, de novo disease at diagnosis versus systemic recurrence) and BC subtype on survival rates. Material and Methods: We evaluated 211 ER+ advanced BC (ABC) patients, treated between 1997 and 2017. Results: The median overall survival (OS) was 37 months. Median OS for the period 1997/2006 and 2007/2017 were 33 and 42 months, respectively (p = 0.47). Luminal A, ABC stage IV disease at diagnosis displayed better OS rates than Luminal B stage IV tumors (100 and 32 months respectively, p < 0.01). Conclusions: Clinical presentation (stage IV vs. systemic recurrence) and tumor subtype are key determinants of OS in ABC.
Antecedentes: Casi el 80% de los casos de cáncer de mama (CM) son positivos para receptores de estrógenos (RE+). Éstos se caracterizan por una mejor sobrevida y respuesta a terapia endocrina. Objetivo: Caracterizar a pacientes con CM avanzado (CMA), RE+, y determinar sobrevida según presentación clínica y subtipos. Material y Métodos: Analizamos en nuestra base de datos los antecedentes de 211 pacientes con CMA RE+, tratados en nuestra institución en el período 1997-2017. Se evaluó el impacto de la presentación clínica (estadio IV al diagnóstico, enfermedad de novo, versus recurrencia sistémica) y subtipo de CM, en los niveles de sobrevida. Resultados: La mediana de sobrevida global (SG) fue de 37 meses. La mediana de SG para el período 1997/2006 y 2007/2017 fue de 33 y 42 meses; respectivamente (p = 0,47). Pacientes con CMA, estadio IV, Luminal A al momento del diagnóstico mostraron mejores tasas de SG frente al estadio IV del Luminal B (100 y 32 meses respectivamente (p < 0,01). Conclusiones: La presentación clínica (estadio IV, de novo, versus recurrencia sistémica) y subtipo son determinantes clave de la SG en CMA.

Breast cancer (BC) is the most common malignancy in women. We retrieved medical records from >2,000 Chilean BC patients over the 1997-2018 period. The objective was to assess changes in clinical presentation or prognosis of our patients throughout these 20 years of practice. Although most variables did not display significant variations, we observed a progressive increase in stage IV BC over this period. Our data showed that tumour stage III/IV or HER2-enriched subtype tumours were associated with poorer prognosis. In contrast, we found that patients diagnosed by mammography had better overall survival. We speculate that better screenings and more sensitive imaging could explain the unexpected rise in stage IV cases. Our results support mammography screenings as an effective measure to reduce BC-related mortality.

Objective: Tumor response to neoadjuvant chemotherapy (NAC) in breast cancer (BC) patients is a predictor for overall survival. The aim of our study was to determine a relationship between the neutrophil to lymphocyte ratio (NLR) prior to NAC, BC subtypes and the probability of a pathologic complete response (pCR). Materials and Methods: Medical records were collected retrospectively from Centro de Cancer at Red Salud UC-Christus. Clinical data collected included peripheral blood cell counts, BC subtype at diagnosis and the pathology report of surgery after chemotherapy. Results: A total of 88 patients were analyzed. Approximately, a 25% had a pCR, and displayed a significant correlation between BC subtype and pCR (p= 0.0138 Chi2); this was more frequent in epidermal growth factor receptor type 2 (HER2) enriched subtype patients (54%). Luminal B BC patients with a pCR had significantly lower NLR levels (t test, p= 0.0181). Conclusions: HER2-enriched tumors had a higher probability of pCR. In Luminal B tumors, NLR had a statistically significant relationship with the probability of pCR. In this subtype, NLR could be a useful biomarker to predict tumor response to NAC. Further studies including other clinical parameters for systemic inflammation such as platelet counts, intratumoral NLR or body mass index could help identify patients that would get the most benefit from NAC.

INTRODUCTION: The optimal management of breast lesions with atypia (BLA), detected in percutaneous biopsies after screening mammograms, is a controversial issue. The aim of this paper is to compare histological diagnosis by percutaneous biopsy with the results of the surgical biopsy of these lesions and to analyse the changes to clinical approach this would imply. METHOD: A retrospective study was carried out on patients operated on between June 2007 and June 2017 with a diagnosis of BLA. One hundred and forty-seven patients were identified with a pre-operative diagnosis of flat epithelial atypia (FEA), atypical ductal hyperplasia (ADH), atypical lobular hyperplasia, lobular carcinoma in situ and other atypia. RESULTS: The average age at diagnosis of BLAs was 52 ± 9.4 years. Radiologically, the lesions presented as microcalcifications in 79%, nodules in 15.6% and other lesions 5.4%. 73.5% of these were biopsied by means of digital stereotaxis. All of the patients analysed underwent a partial mastectomy. Changes in a biologically high-risk lesion were observed in 26.5% of the surgical specimens, of which 75.5% corresponded with ADH and FEA. In the percutaneous biopsies consistent with ADH (40.1%), ductal carcinoma was discovered in 6.8% (5.1% in situ and 1.7% invasive), which implied specific, multi-disciplinary management. Of the FEAs, 84.8% required a second treatment (surgery and/or hormone therapy ± radiotherapy, depending on whether it concerned FEA 59.6%, ADH 21.2% or ductal carcinoma in situ 3.8%). CONCLUSION: These data show the clinical relevance in the diagnosis of ADH and FEA in percutaneous biopsies. For the diagnosis of FEA in particular, the associated risk of biologically high-risk lesions and ductal carcinoma is made evident.
RESUMO
Metastatic breast cancer (MBC) management is based on systemic treatment (ST), while the local therapy role remains controversial. We present the case of a 36-year-old woman with a diagnosis of hormone receptor-positive and human epidermal growth factor receptor type 2-positive breast cancer and isolated sternal metastasis, who received neoadjuvant ST with complete remission and later primary tumour surgery. Oligometastatic patients are a subgroup of MBC that can benefit from aggressive local therapies, even with curative intent.
RESUMO
The association of granulomatous lobular mastitis and carcinoma of the breast is very infrequent. We present the case of a 44-year-old woman with concurrent granulomatous lobular mastitis with coryneform bacteria and ductal carcinoma in situ in the same breast.
RESUMO
Background: HER2+ breast cancer (BC) subtype overexpresses the Human Epidermal growth factor Receptor type-2 (HER2) and is characterized by its aggressiveness and its high sensitivity to monoclonal antibody-based HER2-targeted therapies. Aim: To assess the prognosis and evaluate the impact of novel anti-HER2 therapies on advanced HER2+ BC patients treated at our institution over the last decades. Material and Methods: Analysis of the patient database at a cancer center of a university hospital. Information about the subtype of cancer was obtained in 2,149 of 2,724 patients in the database. Eighteen percent of the latter were HER2+. We analyzed data of 83 of these patients with advanced disease. Results: Median overall survival (OS) was 24 months. For patients treated between 1997-2006 median OS was 17 months and for those treated in the period 2007-2017 median OS was 32 months (p = 0.09). Conclusions: A non-significant trend towards better survival in the last decade was observed. HER2+ BC overall survival has improved in our center. This can be probably attributed to the use of novel more effective anti-HER2 therapies.

Introduction: Breast cancer can be classified into subtypes based on immunohistochemical markers, with Ki67 expression levels being used to divide luminal BC tumors in luminal A and B subtypes; however, Ki67 is not routinely determined due to a lack of standardization. Objective: To evaluate histological grade and Eliminate: the mitotic index to determine if they can be used as an alternative method to Ki67 staining for luminal subtype definition. Methods: We evaluated estrogen receptor positive breast cancer tissue samples. Pathological analysis included determination of Ki67. A low level of Ki67 was defined as <14% positive cells. Results: We evaluated 151 breast cancer samples; 24 (15,9%) were classified as I; 74 as HG II (49%), and 53 (35,1%) as HG III. The median value for Ki67 was 13% (range: <1% - 82%) and for MI was 2 (0-12). Histological grade I tumors exhibited Ki67 values significantly lower than HG II and III tumors (Anova, Tamhane test p=0,001). A higher Ki67 value was related to a higher MI (Rho Sperman p=0,336; R2= 0,0273). ROC curve analysis determined that a MI ≥ 3 had a sensibility of 61.9% and specificity of 66.7% in predicting a high Ki67 value (≥14%) (area under the curve: 0,691; p =0,0001). A HG I tumor or HG II-III with MI ≤2, had a high probability of corresponding to a LA tumor (76,3%), as defined using Ki67 expression, while the probability of a LB subtype was higher with HG II-III and a MI ≥3 (57.4%). Global discrimination was 68.1%. Conclusions: For the LA subtype, our predictive model showed a good correlation of HG and MI with the classification based on Ki67<14%. In the LB subtype, the model showed a weak correlation; therefore Ki67 determination seems to be needed for this group of patients.

Background: Pathological factors, based mainly on immunohistochemistry (IHC) and histological differentiation, are mostly used to differentiate breast cancer (BC) subtypes. Our present aim was to describe the characteristics and survival of a relapsing BC patient cohort based on clinico-pathologic subtypes determined for the primary tumors. Methods: We used a clinico- pathological definition of BC subtypes based on histological grade (HG), estrogen receptor (ER), progesterone receptor (PgR),and epidermal growth factor receptor type 2 (HER2) expression assessed by IHC. We determined variables associated with loco-regional recurrence (LRR), second primaries (SP), systemic recurrence (SR) and post-recurrence survival (PRS). Results: Out of 1,702 patients, 240 (14%) had an event defined as recurrence. Those with recurrent disease were significantly younger than those without,and were initially diagnosed at more advanced stages, with larger tumors, greater lymph nodal involvement and higher HG. With a median follow up of 61 months (1-250), 4.6% of patients without recurrence and 56.6% of patients with an event defined as recurrence had died. The median PRS for the LRR group was 77 months; 75 months for those who developed a SP and 22 months for patients with an SR (p <0.0001). In SR cases, the median PRS was shorter for ER- tumors than for ER+ tumors (15 vs. 26 months, respectively; p = 0.0019, HR 0.44; CI: 0.25-0.44). Conclusions: Subtype, defined through classic histopathologic parameters determined for primary tumors, was found to eb related to type of recurrence and also to prognosis after relapse.
RESUMO
Vasomotor symptoms are one of the main reasons for climateric women to consult a physician. Hormone therapy is the first treatment choice, but it is not indicated to all patients. Veralipride is an option for those who cannot or will not try hormone treatment. The Mexican Association for the Study of Climateric (AMEC) assembled an interdisciplinary group of medical experts so that they revised the medical literature on the subject and reached a consensus on veralipride indication, doses, counterindications and safety. The recommendations of the consensus conference on veralipride are: (1) Physicians must be familiar with its indication, side effects, pharmacokinetics and dosage. (2) Patients must be informed on other therapeutical options. (3) Patients' mental and neurological state must be evaluated, in particular to identify movement disorders, extrapyramidal symptoms (tremor or dystonia), anxiety and depression that can be mistaken for climateric symptoms. (4) Any adverse effect associated with the drug must be reported. (5) A random multicenter trial must be carried out in order to identify the frequency and severity of side effects, and (6) Written information on possible health risks when using the drug must be provided.
