RESUMO

BACKGROUND: Limited data are available regarding the real-world effectiveness and safety of Cyclin Dependent Kinase 4/6 inhibitor (CDK4/6i) (palbociclib/ribociclib) just as a first-line treatment for patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR + /HER2‒) metastatic breast cancer (MBC). OBJECTIVE: To assess whether clinical or demographic characteristics limit access to first-line CDK4/6i treatment in clinical practice in the Autonomous Community of Andalusia (Spain) between November 2017 and April 2020. In addition, effectiveness will be described in an exploratory analysis. METHODS: Physicians from 12 centers participated in selecting demographic and clinical characteristics, treatment, and outcome data from women with HR + /HER2- MBC treated with or without CDK4/6i in addition to hormonal in the first-line setting, in a 3:1 proportion. Kaplan-Meier analysis estimated progression-free rates (PFRs) and survival rates (SRs). RESULTS: A total of 212 patients were included, of whom 175 (82.5%) were in the CDK4/6i treatment group and 37 (17.5%) were in the non-CDK4/6i treatment group (control group). Patients in the CDK 4/6i treatment group were younger (p = 0.0011), the biopsies of the metastatic site at the moment of the relapse were most commonly performed (p = 0.0454), and had multiple metastatic sites (p = 0.0025). The clinical benefit rate (CBR) was 82.3% in the CDK4/6i group and 67.8% in the control group. Median time to a progression event or death (PFS) was 20.4 months (95%CI 15.6-28) in the CDK4/6i group and 12.1 months (95%CI 7.9-not reached) in the control group. CONCLUSIONS: Younger patients, biopsies of metastatic disease and with multiple metastatic sites were more frequently treated with CDK4/6i in our daily clinical practice.

RESUMO

OBJECTIVE: To determine whether adenomyosis is present in the cornual portion of hysterectomies of symptomatic sterilization device users and in patients hysterectomized for different benign causes and who presented with pelvic pain and/or menstrual alterations. METHODS: An observational, analytical, cross-sectional, single-center, retrospective cohort study was conducted in a secondary level hospital. Cohort 1 consisted of women who had Essure® hysteroscopic sterilization devices inserted between 2009 and 2017, who developed gynecologic symptoms (pelvic pain, heavy menstrual bleeding, and/or abnormal uterine bleeding) and who underwent a hysterectomy for explantation of the devices. Cohort 2 consisted of women with the same gynecologic symptoms, who underwent a hysterectomy for other benign causes. All surgeries were performed by the gynecology team between 2018 and 2022. A descriptive and comparative analysis of sociodemographic, clinical characteristics, and pathologic findings between cohorts was made. RESULTS: In total, 96 patients were studied (cohort 1 included 34 women, cohort 2 included 62 women). Pelvic pain was found to be more frequent in the cohort of Essure users (76.47% vs. 50%, P = 0.012), with a ratio of three times higher in this group (odds ratio 3.25, 95% confidence interval 1.27-8.28). Adenomyosis was more frequently found in the Essure group, both at corporal and cornual portions, the latter being five times higher in this cohort (relative risk = 5.47; 95% confidence interval 1.17-25.64). CONCLUSIONS: The present study may be the first to describe cornual adenomyosis related to Essure devices. These devices may play a role in the development of adenomyosis and, consequently, pelvic pain. However, causality is difficult to establish.

RESUMO

PURPOSE: HER2-targeted therapies have dramatically improved outcomes of patients with HER2-positive breast cancer (BC), as demonstrated in neoadjuvant trials. This study aims to provide real-world evidence on the use and effectiveness of combined pertuzumab, trastuzumab and chemotherapy (CT) in early-stage HER2-positive BC. METHODS: A retrospective, multicentre study was conducted on patients diagnosed with HER2-positive early BC treated with neoadjuvant pertuzumab and trastuzumab plus CT at 13 Spanish sites. The primary endpoint was pathological complete response (pCR). RESULTS: A total of 310 patients were included. Pertuzumab and trastuzumab were combined with anthracyclines and taxanes, carboplatin and docetaxel, and taxane-based CT in 77.1%, 16.5%, and 6.5% of patients, respectively. Overall, the pCR rate was 62.2%. The pCR was higher amongst patients with hormone receptor-negative tumours and with tumours expressing higher levels of Ki-67 (> 20%). After postoperative adjuvant treatment, 13.9% of patients relapsed. Those patients who did not achieve pCR, with tumours at advanced stages (III), and with node-positive disease were more likely to experience distant relapse. Median overall survival (OS) and distant disease-free survival (D-DFS) were not reached at the study end. The estimated mean OS and D-DFS times were 7.5 (95% CI 7.3-7.7) and 7.3 (95% CI 7.1-7.5) years, respectively (both were significantly longer amongst patients who achieved pCR). Grade 3-4 anti-HER2 related toxicities were reported in six (1.9%) patients. CONCLUSION: Neoadjuvant pertuzumab and trastuzumab plus CT achieve high pCR rates in real-life patients with HER2-positive early BC, showing an acceptable safety profile. Innovative adjuvant strategies are essential in patients at high risk of distant disease recurrence.

RESUMO

PURPOSE: To analyze the results of the telemedicine screening program for diabetic retinopathy (DR) in patients with type 1 diabetes conducted by the Endocrinology and Nutrition Management Unit of Virgen del Rocío University Hospital. METHODS: This cross-sectional study comprised patients with type 1 diabetes mellitus (DM) in our DR screening program from January 2018 to November 2020. Fundus photographs are performed by trained nurses and reviewed by a trained endocrinologist. Those suggestive of pathology are sent to ophthalmology through a telematic program for review. RESULTS: Of the 995 fundus photographs evaluated, 646 (65.3%) showed no evidence of DR, 327 (33.1%) presented possible DR, and 16 (1.6%) were not gradable. The diagnosis was confirmed in 254 patients after reviewing by ophthalmology, and the screening program achieved a positive predictive value for DR of 77.7%. Seventy-three were excluded by ophthalmology due to the absence of DR (false positive rate - 22.3%). In 92.5% of the cases classified by the ophthalmologist, the degree of DR was mild or very mild. CONCLUSION: Our telemedicine screening program for DR in patients with type 1 DM is consistent with the literature. Effective screening for DR is performed, with patients diagnosed in the early stages. Telemedicine programs facilitate efficient communication among healthcare personnel.

RESUMO

INTRODUCTION: In severe forms of obesity there is a high prevalence of psychopathological comorbidity. Psychiatric evaluation is an important component of comprehensive obesity care and contributes to optimizing therapeutic results after bariatric surgery. OBJECTIVE: To assess the effectiveness of psychometric tests used in the protocol for selecting patients for bariatric surgery. MATERIAL AND METHODS: Retrospective naturalistic observational study of 100 patients who were candidates for bariatric surgery. Patients who complete the psychometric protocol and the psychiatric interview between January 2019 and June 2021 are included. Two groups are formed: those considered unfit for any psychopathological reason and those considered fit. To evaluate the effectiveness of the tests used, ROC curves will be used. The sensitivity and specificity values of each test used will be obtained. RESULTS: 97 patients included, aged between 20 and 61 years, 64.9% women. 51.5% had a family history and 38.1% a personal history of any psychiatric disorder. Regarding the area under the curve, the scales that presented a value greater than 0.7 were the YFAS total score (0.771), HADS-D (0.757), the Edinburgh Bulimia total score (0.747), the severity score of YFAS (0.722) and Edinburgh Bulimia Severity Score (0.705). The most frequent diagnoses as a cause of exclusion were Food Addiction 8 (20.5%) and Generalized Anxiety Disorder (GAD) 6 (15.5%). CONCLUSIONS: The YFAS, BITE and HADS-A scales were useful to discriminate those patients considered unsuitable for bariatric surgery for any psychopathological cause.

RESUMO

BACKGROUND: Although there is scientific evidence of the presence of immunometabolic alterations in major depression, not all patients present them. Recent studies point to the association between an inflammatory phenotype and certain clinical symptoms in patients with depression. The objective of our study was to classify major depression disorder patients using supervised learning algorithms or machine learning, based on immunometabolic and oxidative stress biomarkers and lifestyle habits. METHODS: Taking into account a series of inflammatory and oxidative stress biomarkers (C-reactive protein (CRP), tumor necrosis factor (TNF), 4-hydroxynonenal (HNE) and glutathione), metabolic risk markers (blood pressure, waist circumference and glucose, triglyceride and cholesterol levels) and lifestyle habits of the participants (physical activity, smoking and alcohol consumption), a study was carried out using machine learning in a sample of 171 participants, 91 patients with depression (71.42% women, mean age = 50.64) and 80 healthy subjects (67.50% women, mean age = 49.12). The algorithm used was the support vector machine, performing cross validation, by which the subdivision of the sample in training (70%) and test (30%) was carried out in order to estimate the precision of the model. The prediction of belonging to the patient group (MDD patients versus control subjects), melancholic type (melancholic versus non-melancholic patients) or resistant depression group (treatment-resistant versus non-treatment-resistant) was based on the importance of each of the immunometabolic and lifestyle variables. RESULTS: With the application of the algorithm, controls versus patients, such as patients with melancholic symptoms versus non-melancholic symptoms, and resistant versus non-resistant symptoms in the test phase were optimally classified. The variables that showed greater importance, according to the results of the area under the ROC curve, for the discrimination between healthy subjects and patients with depression were current alcohol consumption (AUC = 0.62), TNF-α levels (AUC = 0.61), glutathione redox status (AUC = 0.60) and the performance of both moderate (AUC = 0.59) and vigorous physical exercise (AUC = 0.58). On the other hand, the most important variables for classifying melancholic patients in relation to lifestyle habits were past (AUC = 0.65) and current (AUC = 0.60) tobacco habit, as well as walking routinely (AUC = 0.59) and in relation to immunometabolic markers were the levels of CRP (AUC = 0.62) and glucose (AUC = 0.58). In the analysis of the importance of the variables for the classification of treatment-resistant patients versus non-resistant patients, the systolic blood pressure (SBP) variable was shown to be the most relevant (AUC = 0.67). Other immunometabolic variables were also among the most important such as TNF-α (AUC = 0.65) and waist circumference (AUC = 0.64). In this case, sex (AUC = 0.59) was also relevant along with alcohol (AUC = 0.58) and tobacco (AUC = 0.56) consumption. CONCLUSIONS: The results obtained in our study show that it is possible to predict the diagnosis of depression and its clinical typology from immunometabolic markers and lifestyle habits, using machine learning techniques. The use of this type of methodology could facilitate the identification of patients at risk of presenting depression and could be very useful for managing clinical heterogeneity.

RESUMO

OBJECTIVES: To evaluate clinical data in women who underwent Essure® hysteroscopic sterilization and to determine whether this sterilization technique plays a role in developing new-onset symptoms. STUDY DESIGN: An observational, retrospective, single-center study. It was conducted in a secondary level hospital. It included 804 women who had Essure® hysteroscopic sterilization from 2009 to 2017. Charts from these women were reviewed from June 2009 to November 2019, searching for the development of gynecological symptoms (pelvic pain and bleeding disorders) and non-gynecological symptoms (bloating, joint pain, fatigue, headache, alopecia, allergy and depression). The sample was divided into two groups depending on whether they had developed gynecological symptoms (symptomatic group) or not (asymptomatic group), and a descriptive and comparative analysis was made between them. The impact of the global social alarm in 2015 regarding adverse events attributed to the devices, the development of non-gynecological symptoms, and the treatments required, including conservative and surgical options, were also described. RESULTS: Out of 804 women who had Essure® devices placed, 541(67.29%) remained asymptomatic, 263(32.71%) developed gynecological symptoms, and 41 of these (15.5% of the total sample) requested Essure® surgical removal. Pelvic pain was the most frequent symptom and the main reason for surgical removal. Bleeding alterations were the second most frequent symptom. Up to 55.89% described the symptoms after the social alarm. Non-gynecological symptoms were statistically significantly more frequent in the symptomatic group. CONCLUSIONS: More than a half of the women who underwent Essure® sterilization remained asymptomatic. The new-onset symptoms attributed to the devices are the minority and causality is difficult to establish. IMPLICATIONS STATEMENT: Our research provides new follow-up data about Essure® hysteroscopic sterilization. Association between gynecological symptoms and Essure® devices is difficult to demonstrate and some confounding factors may be implicated. The results we described, may guide and counsel medical-patient decisions for the treatment of symptoms related to the devices, including surgical removal.

RESUMO

BACKGROUND: Alterations in cognitive performance have been described in patients with major depressive disorder (MDD). However, the specific risk factors of these changes are not yet known. This study aimed to explore whether inmunometabolic parameters are related to cognitive performance in MDD in comparison to healthy controls (HC) METHODS: Sample consisted of 84 MDD patients and 78 HC. Both groups were compared on the results of cognitive performance measured with the Cambridge Neuropsychological Test Automated Battery (CANTAB), the presence of metabolic syndrome (MetS) and an inflammatory/oxidative index calculated by a principal component analysis of peripheral biomarkers (tumor necrosis factor, C-reactive protein and 4-hydroxynonenal). A multiple linear regression was carried out, to study the relationship between inmunometabolic variables and the global cognitive performance, being the latter the dependent variable. RESULTS: Significant differences were obtained in the inflammatory/oxidative index between both groups (F(1157)= 12.93; p < .001), also in cognitive performance (F(1157)= 56.75; p < .001). The inmunometabolic covariate regression model (i.e., condition (HC/MDD), sex, age and medication loading, MetS, inflammatory/oxidative index and the interaction between MetS and inflammatory/oxidative index) was statistically significant (F(7157)= 11.24; p < .01) and explained 31% of variance. The condition, being either MDD or HD, (B=-0.97; p < .001), age (B=-0.28; p < .001) and the interaction between inflammatory/oxidative index and MetS (B=-0.38; p = .02) were factors associated to cognitive performance. LIMITATIONS: Sample size was relatively small. The cross-sectional design of the study limits the possibilities of analysis. CONCLUSIONS: Our results provide evidence on the conjoint influence of metabolic and inflammatory dysregulation on cognitive dysfunction in MDD patients. In this way, our study opens a line of research in immunometabolic agents to deal with cognitive decline associated with MDD.

RESUMO

OBJECTIVE: The primary objective of the study is to compare the  effectiveness of trastuzumab-chemotherapy with and without  pertuzumab. As a secondary objective, we seek to evaluate the cardiac  safety of the treatment. METHOD: Retrospective observational study including all patients treated with either pertuzumab-trastuzumab-chemotherapy (n = 10) or  trastuzumab-chemotherapy (n = 13) (January 2015-December 2018) in a specialty hospital, which met the criteria established by the  Commission Central for the Optimization and Harmonization of the  pharmacotherapy of the Andalusian Health Service for the use of  pertuzumab in neoadjuvance: HER2 positive tumor, negative hormonal  receptors, with high risk of relapse (tumor > 2 cm or lymph node  involvement). To assess effectiveness, the complete pathological  response was used. For cardiac safety, the decrease in left ventricular  ejection fraction greater than 10% was employed. RESULTS: Complete pathological response was superior in the  pertuzumab group (70.0% vs. 30.8%). Cardiac safety was similar in  both. CONCLUSIONS: For patients with HER2 positive tumors and negative hormonal receptors with high risk criteria that receive  pertuzumab, the complete pathological response is superior, with no  increase in cardiac toxicity.


Objetivo: El objetivo primario del estudio es comparar la efectividad trastuzumab-quimioterapia con y sin pertuzumab. Como  objetivo secundario se busca evaluar la seguridad cardiaca del  tratamiento.Método: Estudio observacional retrospectivo que incluyó todas las  pacientes tratadas con pertuzumab-trastuzumab-quimioterapia (n = 10) o trastuzumab-quimioterapia (n = 13) (enero 2015-diciembre 2018) en  un hospital de especialidades, que cumplían los criterios establecidos  por la Comisión Central para la Optimización y Armonización de la  farmacoterapia del Servicio Andaluz de Salud para uso de pertuzumab  en neoadyuvancia: tumor HER2 positivo, receptores hormonales  negativos, con alto riesgo de recaída (tumor > 2 cm o afectación  ganglionar). Para valorar la efectividad se utilizó la respuesta completa  patológica, y para la seguridad cardiaca, el descenso de la fracción de  eyección del ventrículo izquierdo superior al 10%.Resultados: La respuesta completa patológica fue superior en el grupo con pertuzumab (70,0% versus 30,8%). La seguridad cardiaca  fue similar en ambos.Conclusiones: Para las pacientes con tumores HER2 positivo y  receptores hormonales negativos con criterios de alto riesgo que reciben  pertuzumab, la respuesta completa patológica resulta superior,  sin observarse incremento de la toxicidad cardiaca.

RESUMO

BACKGROUND: CD6 is a lymphocyte surface co-receptor physically associated with the T-cell receptor (TCR)/CD3 complex at the center of the immunological synapse. There, CD6 assists in cell-to-cell contact stabilization and modulation of activation/differentiation events through interaction with CD166/ALCAM (activated leukocyte cell adhesion molecule), its main reported ligand. While accumulating evidence is attracting new interest on targeting CD6 for therapeutic purposes in autoimmune disorders, little is known on its potential in cancer. In an attempt to elucidate the in vivo relevance of blocking CD6-mediated interactions in health and disease, we explored the consequences of expressing high circulating levels of a soluble form CD6 (sCD6) as a decoy receptor. METHODS: High sCD6 serum levels were achieved by using transgenic C57BL/6 mice expressing human sCD6 under the control of lymphoid-specific transcriptional elements (shCD6LckEµTg) or wild type either transduced with hepatotropic adeno-associated virus coding for mouse sCD6 or undergoing repeated infusions of recombinant human sCD6 protein. Characterization of sCD6-induced changes was performed by ex vivo flow cytometry and functional analyses of mouse lymphoid organ cells. The in vivo relevance of those changes was explored by challenging mice with subcutaneous or metastatic tumors induced by syngeneic cancer cells of different lineage origins. RESULTS: Through a combination of in vitro and in vivo studies, we show that circulating sCD6 expression induces defective regulatory T cell (Treg) generation and function, decreased CD166/ALCAM-mediated tumor cell proliferation/migration and impaired galectin-induced T-cell apoptosis, supporting the fact that sCD6 modulates antitumor lymphocyte effector function and tumorigenesis. Accordingly, sCD6 expression in vivo resulted in delayed subcutaneous tumor growth and/or reduced metastasis on challenge of mice with syngeneic cancer cells. CONCLUSIONS: Evidence is provided for the disruption of CD6 receptor-ligand interactions as a feasible immunomodulatory approach in cancer.

RESUMO

PURPOSE: Operable triple-negative breast cancers (TNBCs) have a higher risk of relapse than non-TNBCs with standard therapy. The GEICAM/2003-11_CIBOMA/2004-01 trial explored extended adjuvant capecitabine after completion of standard chemotherapy in patients with early TNBC. PATIENTS AND METHODS: Eligible patients were those with operable, node-positive-or node negative with tumor 1 cm or greater-TNBC, with prior anthracycline- and/or taxane-containing chemotherapy. After central confirmation of TNBC status by immunohistochemistry, patients were randomly assigned to either capecitabine or observation. Stratification factors included institution, prior taxane-based therapy, involved axillary lymph nodes, and centrally determined phenotype (basal v nonbasal, according to cytokeratins 5/6 and/or epidermal growth factor receptor positivity by immunohistochemistry). The primary objective was to compare disease-free survival (DFS) between both arms. RESULTS: Eight hundred seventy-six patients were randomly assigned to capecitabine (n = 448) or observation (n = 428). Median age was 49 years, 55.9% were lymph node negative, 73.9% had a basal phenotype, and 67.5% received previous anthracyclines plus taxanes. Median length of follow-up was 7.3 years. DFS was not significantly prolonged with capecitabine versus observation [hazard ratio (HR), 0.82; 95% CI, 0.63 to 1.06; P = .136]. In a preplanned subgroup analysis, nonbasal patients seemed to derive benefit from the addition of capecitabine with a DFS HR of 0.53 versus 0.94 in those with basal phenotype (interaction test P = .0694) and an HR for overall survival of 0.42 versus 1.23 in basal phenotype (interaction test P = .0052). Tolerance of capecitabine was as expected, with 75.2% of patients completing the planned 8 cycles. CONCLUSION: This study failed to show a statistically significant increase in DFS by adding extended capecitabine to standard chemotherapy in patients with early TNBC. In a preplanned subset analysis, patients with nonbasal phenotype seemed to obtain benefit with capecitabine, although this will require additional validation.

RESUMO

La hidatidosis es una zoonosis parasitaria causada por Echinococcus granulosus. Es endémica en Argentina y en la Provincia de Buenos Aires, especialmente al sur de la cuenca del río Salado. Durante 2014 y 2016, se notificaron al Departamento de Zoonosis Rurales 479 casos de hidatidosis; el 12,1% fueron casos confirmados en menores de 18 años de edad. El 59% correspondió al sexo masculino y el grupo de 13 a 17 años fue el más prevalente (47%). El 64% tuvo afectación hepática; 22%, pulmonar; 5%, hepatopulmonar; 5%, esplénica y 4%, cerebral. El 33% de los casos fueron asintomáticos. El 60% residía en el área urbana y, de estos, un 20% no presentó nexo epidemiológico. Esta es una enfermedad de denuncia obligatoria y existen programas provinciales y nacionales que contemplan acciones gratuitas tendientes a controlarla, pero, a pesar de esto, continúa siendo un problema de difícil solución.


Hydatidosis is a parasitic zoonosis caused by Echinococcus granulosus. It is endemic in Argentina and in the province of Buenos Aires, especially to the south of the Rio Salado basin. During 2014 and 2016, the Department of Rural Zoonoses was notified of479 cases of hydatidosis, with 12.1% confirmed in children under 18 years of age. Fifty-nine percent corresponded to males and the group of 13 to 17 years was the most prevalent one (47%). Sixty-four percent had liver involvement, 22% pulmonary involvement, 5% hepatopulmonary involvement, 5% splenic involvement and 4% cerebral involvement. Thirty-three percent of the cases were asymptomatic. Sixty percent resided in urban areas and of these 20% did not present an epidemiological link. This is a disease of mandatory reporting and there are provincial and national programs that contemplate free actions tending to control it, but despite this, it continues to be a difficult problem to solve.

RESUMO

Hydatidosis is a parasitic zoonosis caused by Echinococcus granulosus. It is endemic in Argentina and in the province of Buenos Aires, especially to the south of the Rio Salado basin. During 2014 and 2016, the Department of Rural Zoonoses was notified of 479 cases of hydatidosis, with 12.1% confirmed in children under 18 years of age. Fifty-nine percent corresponded to males and the group of 13 to 17 years was the most prevalent one (47%). Sixty-four percent had liver involvement, 22% pulmonary involvement, 5% hepatopulmonary involvement, 5% splenic involvement and 4% cerebral involvement. Thirtythree percent of the cases were asymptomatic. Sixty percent resided in urban areas and of these 20% did not present an epidemiological link. This is a disease of mandatory reporting and there are provincial and national programs that contemplate free actions tending to control it, but despite this, it continues to be a difficult problem to solve.


La hidatidosis es una zoonosis parasitaria causada por Echinococcus granulosus. Es endémica en Argentina y en la Provincia de Buenos Aires, especialmente al sur de la cuenca del río Salado. Durante 2014 y 2016, se notificaron al Departamento de Zoonosis Rurales 479 casos de hidatidosis; el 12,1% fueron casos confirmados en menores de 18 años de edad. El 59% correspondió al sexo masculino y el grupo de 13 a 17 años fue el más prevalente (47%). El 64% tuvo afectación hepática; 22%, pulmonar; 5%, hepatopulmonar; 5%, esplénica y 4%, cerebral. El 33% de los casos fueron asintomáticos. El 60% residía en el área urbana y, de estos, un 20% no presentó nexo epidemiológico. Esta es una enfermedad de denuncia obligatoria y existen programas provinciales y nacionales que contemplan acciones gratuitas tendientes a controlarla, pero, a pesar de esto, continúa siendo un problema de difícil solución.

RESUMO

The inhibition of apoptotic cell death in T cells through the dysregulated expression of BCL2 family members has been associated with the protection against the development of different autoimmune diseases. However, multiple mechanisms were proposed to be responsible for such protective effect. The purpose of this study was to explore the effect of the T-cell overexpression of BCL2A1, an anti-apoptotic BCL2 family member without an effect on cell cycle progression, in the development of collagen-induced arthritis. Our results demonstrated an attenuated development of arthritis in these transgenic mice. The protective effect was unrelated to the suppressive activity of regulatory T cells but it was associated with a defective activation of p38 mitogen-activated protein kinase in CD4+ cells after in vitro TCR stimulation. In addition, the in vitro and in vivo TH17 differentiation were impaired in BCL2A1 transgenic mice. Taken together, we demonstrated here a previously unknown role for BCL2A1 controlling the activation of CD4+ cells and their differentiation into pathogenic proinflammatory TH17 cells and identified BCL2A1 as a potential target in the control of autoimmune/inflammatory diseases.

RESUMO

OBJECTIVES: The self-determination of blood glucose is relevant for diabetes mellitus (DM) insulin-treated patients. The use of glucometers with advanced features and measuring glycated haemoglobin (HbA1c) may help improve metabolic control. The main objective of this study was to determine the percentage of insulin treated patients who reduced HbA1c by at least 0.4% after 6 months of using Contour and A1CNow+. MATERIALS AND METHODS: Observational, prospective, multicentre study in adult DM insulin treated patients, with HbA1c> 8%. RESULTS: Of the 454 recruited patients analysed, a total of 333 were evaluable. After 6 months the HbA1c decreased (P<.05) in both groups [-0.89 (95% CI -1.01 to -0.76) and -0.98 (95% CI: -1.21 to -0.76), in type 1 and 2 DM, respectively]. An HbA1c reduction of 0.4% was observed in 73% of patients after 6 months of device use. A decrease in the number of patients with HbA1c > 8% was observed, with this reaching: 41% for all, 45% in type 1 DM, and 25% in type 2 DM. In the glycaemic profile, a reduction (P<.05) was observed in pre- and post-prandial glycaemia in both groups (-20.7±36.4 and -37.1±47.1mg/dL, respectively), with 23% pre-prandial glucose < 130mg/dL and post-prandial < 180mg/dL CONCLUSION: The use of glucometers with advanced features, and measuring glycated haemoglobin (HbA1c) may help improve metabolic control and to monitor insulin treated DM patients more closely.

RESUMO

OBJECTIVE: To measure the vascularization and ovarian volume with three-dimensional sonography in patients diagnosed of polycystic ovary syndrome with stimulated ovulation treatment, and to analyse the differences between the patients treated with clomiphen citrate versus clomiphen citrate and metformin. MATERIAL AND METHOD: Therty patients were studied. Twenty ovulation cycles were obtained with clomiphen citrate and 17 with clomiphen citrate plus merformin (added in case of obesity or hyperglucemy/hyperinsulinemia). Ovarian volumes and vascular indexes were studied with 3D-sonography and results were analysed by treatment. RESULTS: There were no statistical differences of ovarian volume by treatment along the cycles, although bigger volume were found in ovulatory cycles compared to non-ovulatory ones (20,36 versus 13,89 ml, p = 0,026). No statistical differences were also found concerning vascular indexes, neither by treatment nor by the obtention of ovulation in the cycle. CONCLUSIONS: Ovarian volume and vascular indexes measured with three-dimensional sonography in patients diagnosed of polycystic ovary syndrome do not show differents values in patients treated with clomiphen citrate alone versus clomiphen citrate plus metformin.

RESUMO

INTRODUCTION: A unicornuate uterus with a rudimentary horn is the most uncommon uterine anomaly of the female genital tract. It has an estimated frequency of one in 100,000 among the fertile female population. This anomaly results from the abnormal maturation of one Müllerian duct with the normal development of the contralateral one. CASE PRESENTATION: We report here the case of a 14-year-old Caucasian girl who came to our hospital with intense dysmenorrhea. Imaging techniques revealed a unicornuate uterus with a rudimentary horn and a large hematosalpinx. We performed a laparoscopic removal of this uterine anomaly without any complication in the postoperative period. CONCLUSION: In our case report, we demonstrate that laparoscopy is the best approach for the treatment of IIb Müllerian abnormalities. Laparoscopy resulted in anatomical and reproductive results equivalent to those offered by a laparotomic approach, but with the additional advantages of minimally invasive surgery, such as better cosmetic results and postoperative period, which are essential for very young patients.
