RESUMO

(1) Background: Non-Hodgkin Lymphoma is a neoplasm that can significantly compromise the immune system, but timely assessment can change the patient outcome. In cancer, the activation of the immune system could lead to the secretion of autoantibodies. (2) Methods: A retrospective cohort study was performed from 2017 to 2019 in patients with Non-Hodgkin Lymphoma diagnosed with a biopsy. (3) Results: We included 39 patients who were newly diagnosed, untreated, and without any autoimmune disease previously reported. Thirty patients had the presence of autoantibodies (antiphospholipid antibodies, anti-cytoplasmic neutrophils antibodies, antinuclear antibodies), and nine were without autoantibodies. There were no statistical differences among groups regarding clinical, demographic, staging, and prognosis characteristics. Also, there were no differences in the outcomes of the patients after finishing chemotherapy and one year after initiating treatment. (4) Conclusions: Further investigations must be conducted regarding an extended panel of autoantibodies because the panel of autoantibodies in this study did not show a relationship between the presence and the clinical outcome of the patients.

RESUMO

Head and neck cancer (H&NC) is a diverse category of tumors related to malignancies in the common aerodigestive pathway, with high metabolic rate, poor nutritional and treatment outcomes, and elevated mortality despite the best standard treatment. Herein, we focus on determining how the phase angle (PA) differs across sex as a predictor of poor prognosis, low quality-of-life (QoL) scores, and mortality in patients with head and neck cancer. This follow-up study presents a sex-differential analysis in a prospective cohort of 139 head and neck cancer patients categorized by sex as male (n = 107) and female (n = 32). Patients were compared in terms of nutritional, biochemical, and quality-of-life indicators between low and normal PA in women (<3.9° (n = 14, 43.75%) and ≥3.9°) and men (<4.5° (n = 62, 57.9%) and ≥4.5°). Our results show that most patients were in locally advanced clinical stages (women: n = 21 (65.7%); men: n = 67 (62.6%)) and that patients with low PA had a lower punctuation in parameters such as handgrip strength, four-meter walking speed, albumin, C-reactive protein (CRP), and CRP/albumin ratio (CAR), as well as the worst QoL scores in functional and symptomatic scales in both the male and female groups. A comparison between sexes revealed significant disparities; malnourishment and tumor cachexia related to an inflammatory state was more evident in the women's group.

RESUMO

The phase angle, an indicator of muscle mass status and membrane cell integrity, has been associated with low survival, poorer clinical outcomes, and worse quality of life among cancer patients, but information on women with uterine cervical cancer (UCCa) is scarce. In this prospective study, we used a bioelectrical impedance analyzer to obtain the PA of 65 women with UCCa. We compared the health-related quality of life and inflammatory and nutritional indicators between low PA and normal PA. The mean age was 52 ± 13. The low PA and normal PA groups differed in terms of the C-reactive protein (15.8 ± 19.6 versus 6.82 ± 5.02, p = 0.022), glucose (125.39 ± 88.19 versus 88.78 ± 23.08, p = 0.021), albumin (3.9 ± 0.39 versus 4.37 ± 0.30, p = 0.000), EORTC QLQ-C30 loss of appetite symptom scale score (33.33 (0.0-100.00) versus 0.0 (0.0-0.0), p = 0.005), and EORTC QLQ-CX24 menopausal symptoms scale score (0.0 (0.0-33.33) versus 0.0 (0.0-100.0), p = 0.03). The main finding of the present study is the interaction between PA and obesity as critical cofactors in the UCCa adeno and adenosquamous histologic variants, to a greater extent than cervical squamous cell carcinoma.

RESUMO

In patients with head and neck cancer, malnutrition is common. Most cases are treated by chemo-radiotherapy and surgery, with adverse effects on the aerodigestive area. Clinical and biochemical characteristics, health-related quality of life, survival, and risk of death were studied. The selected subjects were divided into normal- and low-phase-angle (PA) groups and followed up for at least two years. Mean ages were 67.2 and 59.3 years for low and normal PA, respectively. Patients with PA < 4.42° had significant differences in age, anthropometric and biochemical indicators of malnutrition, and inflammatory status compared to patients with PA > 4.42°. Statistical differences were found in the functional and symptom scales, with lower functional scores and higher symptom scores in patients with low PA. Median survival was 19.8 months for those with PA < 4.42° versus 34.4 months for those with PA > 4.42° (p < 0.001).The relative risk of death was related to low PA (2.6; p < 0.001). The percentage of living patients (41.7%) is almost the same as the percentage of deceased subjects (43.1%; p = 0.002), with high death rates in patients with PA < 4.42°. Phase angle was the most crucial predictor of survival and a risk factor for death in the studied cases.

RESUMO

Insulin levels, adipocytokines, and inflammatory mediators trigger benign breast disease (BBD) and breast cancer (BC). The relationship between serum adipocytokines levels, overweight-obesity, metabolic disturbs, and BC is unclear. Methods: To analyze the serum levels of the adipocytokines, insulin, and the HOMA IR in women without breast disease, with BBD or BC, and the role of these as risk factors for benign breast disease or breast cancer. Results: Adipsin values > 0.91 and visfatin levels > 1.18 ng/mL represent a risk factor to develop BBD in NBD lean women (OR = 18; and OR = 12). Data in overweight-obese women groups confirm the observation due to insulin levels > 2.6 mU/mL and HOMA IR > 0.78, with OR = 60.2 and 18, respectively; adipsin OR = 26.4, visfatin OR = 12. Breast cancer risk showed a similar behavior: Adipsin risk, adjusted by insulin and visfatin OR = 56 or HOMA IR and visfatin OR = 22.7. Conclusion: Adipose tissue is crucial for premalignant and malignant tissue transformation in women with overweight-obesity. The adipocyte−breast epithelium interaction could trigger a malignant transformation in a continuum, starting with BBD as premalignant disease, especially in overweight-obese women.

RESUMO

One of the main groups of lipids is phospholipids, which are mainly involved in forming cell membranes. Neoplastic processes such as cell replication have increased lipid synthesis, making tumor cells dependent on this synthesis to maintain their requirements. Antiphospholipid antibodies attack phospholipids in the cell membranes. Three main types of antiphospholipid antibodies are recognized: anti-ß2 glycoprotein I (anti-ß2GP-I), anticardiolipin (aCL), and lupus anticoagulant (LA). These types of antibodies have been proven to be present in hematological neoplasms, particularly in LH and NHL. This review on antiphospholipid antibodies in hematological neoplasms describes their clinical relationship as future implications at the prognostic level for survival and even treatment.

RESUMO

BACKGROUND: Health-related quality of life (QoL) is a measure that allows us to know the patient's perception of well-being and how it is affected by their disease and treatments. In cancer patients, sarcopenia has been associated with low scores on various instruments used to assess the QoL; however, little information is available on the effects of sarcopenia and sarcopenic obesity on the QoL of patients with head and neck cancer (H&NC). METHODS: In this cross-sectional study with 71 H&NC patients aged between 40 and 80 years, we describe the scores on the instruments EORTC QLQ C-30 and EORTC QLQ-H&N35 according to the sarcopenia phenotype (NSG, nonsarcopenic group; SG, sarcopenic group; and SOG, sarcopenic obesity group), hand-grip strength, gait speed, total lymphocyte count, albumin, cholesterol and C-reactive protein, and the relationships between these variables. RESULTS: The prevalence of sarcopenia and sarcopenic obesity was 48% and 28%, respectively. The QoL analysis showed that NSG had higher scores on the physical functioning scale [NSG 93 (83-100); SG 73 (52-88); SOG 83 (53-93), P = .009] and lower scores on the fatigue scale [NSG 11 (0-22); S 39 (30-67); SOG 44 (14-56); P = .004]. The NSG had a higher hand-grip strength (31.1 kg) than SG (24.1 kg, P = .007) and SOG (26.3 kg, P = .001), and a lower C-reactive protein. The SG and SOG showed no differences between them. CONCLUSIONS: Patients with sarcopenia or sarcopenic obesity have lower physical performance and a higher level of fatigue than nonsarcopenic patients. This loss of function can maintain or worsen sarcopenia due to the patient's self-restraint in physical exertion that encourages an increase in muscle tissue.

RESUMO

Neoplasms result from changes in the mechanisms of growth, differentiation, and cellular death. Cancers are of high clinical relevance due to their prevalence and associated morbidity and mortality. The clinical and biological diversity of cancer depends mainly on cellular origin and degree of differentiation. These changes result from alterations in molecular expression that generate a complex clinical, biochemical, and morphologic phenotype. Although cancer is associated with a hypercoagulable state, few cancers result in a thrombotic event. Many factors influence thrombotic incidence, such as advanced disease, central catheter placement, chemotherapy, neoplasia, and surgery. The pro-coagulant state is associated with anomalies in the vascular wall, blood flow, blood constituents (tissue factor, thrombin), coagulation state, and cell growth factors. Tumor cells perpetuate this phenomenon by releasing tissue factor, inflammatory cytokines, and growth factors. These changes favor cellular activation that gives rise to actions involving coagulation, inflammation, thrombosis, tumor growth, angiogenesis, and tumor metastases. These, in turn, are closely linked to treatment response, tumor aggressiveness, and host survival. Activation of the coagulation cascade is related to these phenomena through molecules that interact in these processes. As such, it is necessary to identify these mediators to facilitate treatment and improve outcomes.

RESUMO

Background: The Wnt/ß catenin pathway promotes bone mineralization stimulating proliferation, differentiation, and survival of osteoblasts; it also inhibits osteoclast differentiation and osteocyte activity. Sclerostin (SOST) and Dickkopf 1 (DKK1) are Wnt/ß catenin pathway inhibitors. Genetic variability in the expression of SOST and DKK1 might be involved in the development of postmenopausal osteoporosis (OP). Aim: To determine whether the SOST rs851056 and DKK1 rs1569198 polymorphisms are associated with OP in Mexican-Mestizo postmenopausal women. Materials and Methods: Two hundred and eighty Mexican-Mestizo postmenopausal women were assessed for their bone mineral density by dual-energy X-ray absorptiometry (DXA). Patients were classified as OP or non-OP. Genomic DNA was extracted from peripheral blood leukocytes. Genetic polymorphisms were analyzed by quantitative polymerase chain reaction using TaqMan probes. Results: The frequency of OP was 40% among the study population. Osteoporotic patients were older (p < 0.001), had a higher frequency of smoking (p = 0.01), and lower body mass index (p < 0.001) compared with the non-osteoporotic patients. The genotypic frequencies of the rs851056 locus of the SOST gene were GG 19%, GC 45%, and CC 35%, whereas the genotypic frequencies of the rs1569198 locus of the DKK1 gene were GG 15%, GA 40%, and AA 44%. In relation to rs851056 locus of the SOST gene, no differences were observed between the OP and non-OP cohorts in the frequencies of the GC polymorphism (48.7% vs. 43.1%). Similarly, analyses of the DKK1 rs1569198 does not demonstrate differences in the GA genotypic frequencies between the OP and non-OP cohorts (42.5% vs. 38.9%). Conclusion: Polymorphisms SOST rs851056 and DKK1 rs1569198 polymorphisms are not associated with OP in Mexican-Mestizo postmenopausal women.

RESUMO

Up to 60% of colorectal cancer (CRC) patients develop malnutrition, affecting treatment effectiveness, increasing toxicity, postoperative complications, hospital stay, and worsening health-related quality of life (HRQOL). This cross-sectional study analyzed data from 48 women and 65 men with CRC. We correlated scores of the scales from the questionnaires EORTC (European Organisation for Research and Treatment of Cancer) Quality of Life Questionnaire Core 30 (QLQ)-C30 and Colorectal Cancer module Colorectal 29 (QLQ-CR29) with patients' body composition and clinical and biochemical indicators of nutritional status. Results: Scores on quality of life were negatively associated with the lymphocyte count (rP = -0.386) and the fat trunk percentage (rP = -0.349) in the women's group. Scores on the physical and role functioning were inversely associated with the adiposity percentage (rP = -0.486 and rP = -0.411, respectively). In men, total skeletal muscle mass (SMM) was positively associated with emotional functioning (rP = 0.450); the trunk SMM was negatively related to fatigue (rP = -0.586), nausea and vomiting (rP = -0.469), pain (rP = -0.506), and financial difficulties (rP = -0.475); additionally, serum albumin was positively related to physical, emotional, and social functioning scales (rPs = 0.395, 0.453, and 0.363, respectively) and negatively to fatigue (rP = -0.362), nausea and vomiting (rP = -0.387), and appetite loss (rP = -0.347). Among the men, the reduced SMM and biochemical, nutritional parameters were related to low scores on the EORTC QLQ-C30 and QLQ-CR29 functioning scales. In conclusion, in patients with CRC, malnourishment could have a profound effect on the patients' functionality and QoL (quality of life).

RESUMO

Biomarkers play a critical role in the medical care of patients with cancer, including in early detection of the disease, diagnostic accuracy, risk stratification, treatment, and follow-up. Biomarkers in hematological malignancies can support the redefinition of the diagnosis and adjustments in the treatment plan. Biomarkers can be classified into 4 categories: (1) protein antigens, (2) cytogenetic abnormalities, (3) genetic polymorphisms, and (4) gene expression. Efforts in genomics, proteomics, and metabolomics to observe new biomarkers that contribute to the development of clinical medicine with greater precision in the strategies that improve prevention, diagnosis, and treatment of patients with malignant hematological disease. New biomarkers should accomplish several issues such as the biological plausibility, methodology used, analytical validation, intellectual property registry, and legal framework of application. This knowledge should be transferred to health professionals who can carry out the process of its implementation in clinical practice.

RESUMO

Multiple myeloma (MM) is characterized by bone pain, pathologic fractures, bone destruction, and secondary hypercalcemia, all these conditions impact on health-related quality of life of patients. The objective was to evaluate the global health state and health-related quality of life in a group of patients with MM who attended a tertiary health-care center of the Instituto Mexicano del Seguro Social in Mexico, through the questionnaires designed by European Organization for Research and Treatment of Cancer (EORTC) quality of life group. Exploratory cross-sectional study in patients with MM treated in a Department of Hematology in a High-Specialty Medical Unit was conducted. Patients older than 18 years of age, men and women, were selected, and their informed written consent was obtained. We included all consecutive cases treated from January 2012 to December 2014. Questionnaires EORTC QLQ-C30, EORTC QLQ-MY20, and EORTC IN-PATSAT-32 were used. We studied 37 patients, 19 (51%) men and 18 women. The mean age was 61.9 years. Twenty-two (59.46%) patients presented with clinical stage III. The mean time for diagnosis was 33.11 months. The most used first-line treatment schedule was melphalan/prednisone/thalidomide (15; 40%). The global health median was 66.67, and symptoms showed a median score of 22.22. Treatment side effects score was 16.67; for general satisfaction, the median score was 75. In conclusion, the patients showed an advanced clinical stage and poor prognosis but had scores higher than 50 in functional scales and lower than 50 for symptom scales. The scores for symptom scales were related to age, renal failure, and disease-free survival. Identification of quality of life and satisfaction of care markers allow for early therapeutic intervention and efficiency and enable a change in quality of life and perception of care in Health Services.

RESUMO

Neoplasms exhibits a high incidence and mortality rates due to their complex and commonly overlapping clinical, biochemical, and morphologic profiles influenced by acquired or inherited molecular abnormalities, cell of origin, and level of differentiation. Obesity appears related to ~20% of cancers including endometrial, esophageal, colorectal, postmenopausal breast, prostate, and renal. Several factors other than obesity, i.e., insulin, insulin-like growth factor, sexual hormones, and adipokines may play a potential role in neoplasia. Cancer-associated hypercoagulable and thrombotic states are influenced by abnormalities in the vascular wall and susceptibility to invasion, interference in blood flow and increase in circulating tissue factor and thrombin, activation of cell growth factors, the presence of a central catheter, chemotherapies, neoplasm type, and surgery. In cancer, thromboembolic complications are the second most frequent cause of death with pulmonary thromboembolism in ~50% of cases postmortem. Thrombosis worsens prognosis as demonstrated with a survival rate as low as 12% per year vs 36% in nonthrombic patients. Deep vein thrombosis is the most frequent thromboembolic complication in cancer. It is usually detected at diagnosis and within the first 3 months of chemotherapy. The underlining mechanisms of this association should be further studied to identify patients at higher risk and develop adequate prevention, diagnostic, and treatment measures. The D-dimer test can be successfully used to assess the fibrinolytic phase of coagulation and as such is routinely used in suspected cases of deep vein thrombosis and pulmonary thromboembolism. In addition, significant advances have been made in understanding the composition and functional capabilities of the gut microbiota in the inflammatory process, obesity, and its roles in cancer; however, the intricate balance that exists within the microbiota may not only affect the host directly, it can also disrupt the entire microbial community. CONCLUSIONS: Cancer is a prothrombotic and inflammatory state in which the activation of coagulation is related to tumor growth, angiogenesis, and metastasis. It is important to identify the relationship between body mass index with these processes and clarify their importance in cancer prognosis. Future research should answer the question if manipulation of resident microbial communities could potentially improve prognosis and treatment outcome.

RESUMO

BACKGROUND: Cytomegalovirus (CMV) pulmonary involvement is rarely associated with IRIS; therefore, limited information is available. CASE PRESENTATION: Here, we describe the case of a 43-year-old HIV-infected male who developed an unusual case of IRIS after cytomegalovirus (CMV) pneumonia. Clinically there was a progressive and paradoxical worsening of respiratory distress, despite being treated for CMV after initiation with antiretroviral therapy. Chest X-ray revealed disseminated infiltrates in both lungs; chest CT-scan showed generalized lung involvement and mediastinal adenopathy. Pulmonary biopsy confirmed CMV pneumonia with the observation of typical viral inclusions on pneumocytes. CONCLUSIONS: CMV pneumonia can be associated with the development of IRIS requiring treatment with immunosuppressant's and immunomodulatory drugs.

RESUMO

Objective To identify correlations of the serum leptin, adiponectin, interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) concentrations with the clinical characteristics, presence of spinal syndesmophytes, and body composition in patients with ankylosing spondylitis (AS). Methods Forty-eight patients with AS were compared with 41 sex- and age-matched controls. Assessment included clinical characteristics and the presence of spinal syndesmophytes. The serum leptin, adiponectin, TNF-α, and IL-6 concentrations were determined. Body composition was evaluated using dual-energy X-ray absorptiometry. Results Patients with AS and controls had similar fat mass and lean mass. Patients with AS had higher serum TNF-α and leptin concentrations than controls (52.3 vs. 1.5 pg/mL and 17.2 vs. 9.0 µg/mL, respectively). The IL-6 and adiponectin concentrations were not significantly different between the two groups. Patients with syndesmophytes had higher leptin concentrations than those without syndesmophytes (22.1 vs. 10.9 µg/mL); this difference remained after adjustment for the body mass index. Conclusion Elevated leptin concentrations are associated with spinal radiographic damage in patients with AS and can serve as a biomarker. Future studies should evaluate whether leptin might be a potential target for treatments to avoid structural damage.

RESUMO

BACKGROUND: Patients with cancer exhibit changes in their hemostatic mechanisms. The D-dimer (D-D) is the most important subproduct of fibrinolysis, and urokinase plasminogen activator receptor (uPAR) is related to invasiveness and metastases, and is overexpressed in neoplastic cells. The objective of this study was to identify in patients with hematological neoplasia, the serum levels of uPAR and D-D, and to determine their effects on outcome. PATIENTS AND METHODS: A cross-sectional study was performed. Clinical and demographic data were obtained from the clinical chart. Determination of uPAR in serum (pg/L) was performed using an enzyme-linked immunosorbent assay, and D-D (µg/dL) using nephelometry. RESULTS: We included 42 patients (35 with lymphomas). Statistically significant differences were found in D-D (P < .001) and uPAR (P < .01) between patients and control participants. Response was an accumulated clinical outcome. We observed statistical differences between groups (P < .001). D-D was positive in 70% of cases. CONCLUSION: We found differences in D-D serum levels and soluble uPAR between control participants and patients with lymphoma. These results indicate that D-D serum levels and soluble uPAR should be considered biomarkers of response and survival in patients with lymphoma.

RESUMO

Bone disease in rheumatoid arthritis (RA) is a complex phenomenon where genetic risk factors have been partially evaluated. The system formed by receptor activator for nuclear factor-κB (RANK), receptor activator for nuclear factor-κB ligand (RANKL), and osteoprotegerin (OPG): RANK/RANKL/OPG is a crucial molecular pathway for coupling between osteoblasts and osteoclasts, since OPG is able to inhibit osteoclast differentiation and activation. We aim to evaluate the association between SNPs C950T (rs2073617), C209T (rs3134069), T245G (rs3134070) in the TNFRSF11B (OPG) gene, and osteoporosis in RA. We included 81 women with RA and 52 healthy subjects in a cross-sectional study, genotyped them, and measured bone mineral density (BMD) at the lumbar spine and the femoral neck. Mean age in RA was 50 ± 12 with disease duration of 12 ± 8 years. According to BMD results, 23 (33.3%) were normal and 46 (66.7%) had osteopenia/osteoporosis. We found a higher prevalence of C allele for C950T SNP in RA. Polymorphisms C209T and T245G did not reach statistical significance in allele distribution. Further studies including patients from other regions of Latin America with a multicenter design to increase the sample size are required to confirm our findings and elucidate if C950T SNP could be associated with osteoporosis in RA.

RESUMO

OBJECTIVE: To evaluate the effect of anti-TNF agents plus synthetic disease modifying antirheumatic drugs (DMARDs) versus DMARDs alone for ankylosing spondylitis (AS) with reduced pulmonary function vital capacity (FVC%). METHODS: In an observational study, we included AS who had FVC% <80% at baseline. Twenty patients were taking DMARDs and 16 received anti-TNF + DMARDs. OUTCOME MEASURES: changes in FVC%, BASDAI, BASFI, 6-minute walk test (6MWT), Borg scale after 6MWT, and St. George's Respiratory Questionnaire at 24 months. RESULTS: Both DMARDs and anti-TNF + DMARDs groups had similar baseline values in FVC%. Significant improvement was achieved with anti-TNF + DMARDs in FVC%, at 24 months, when compared to DMARDs alone (P = 0.04). Similarly, patients in anti-TNF + DMARDs group had greater improvement in BASDAI, BASFI, Borg scale, and 6MWT when compared to DMARDs alone. After 2 years of follow-up, 14/16 (87.5%) in the anti-TNF + DMARDs group achieved the primary outcome: FVC% ≥80%, compared with 11/20 (55%) in the DMARDs group (P = 0.04). CONCLUSIONS: Patients with anti-TNF + DMARDs had a greater improvement in FVC% and cardiopulmonary scales at 24 months compared with DMARDs. This preliminary study supports the fact that anti-TNF agents may offer additional benefits compared to DMARDs in patients with AS who have reduced FVC%.

RESUMO

INTRODUCCTION: Acute lymphoblastic leukemia (ALL) is a clonal disease characterized by a proliferation of immature cells. In immunophenotypic, cytogenetic and molecular studies, it is a heterogeneous disease with diverse manifestations and prognoses. The treatment is complex and is associated with complications during its course. PATIENTS AND METHODS: A prospective study of cohort of patients with ALL. Subjects were recruited consecutively from April 2010 to November 2012 in the Specialties Hospital, /MSS. RESULTS: We included 29 patients with ALL; of 16 females (55%) and 13 males (45%), 18 (64%) were treated with modified BFM, seven (25%) HiperCVAD, and three (11 %) others. In all, 70% achieved complete remission, and 8.5% partial responses. Induction mortality in five patients (17%). Consolidation mortality in three (13%). Relapse 33%, with a mean of eight months (5- 16 months), overall survival five months. At 26 months of follow-up, 13 patients (45%) maintained RC. Disease-free survival of 10 months and overall survival of 12 months was observed. CONCLUSION: The majority of patients, regardless of risk, reach complete remission. We found that the clinical and biological characteristics showed no significant differences related to the outcome. lmmunochemotherapy treatment may improve response.

RESUMO

Objetivo. Identificar las investigaciones sobre calidad de la atención en el IMSS. Material y métodos. Estudio bibliométrico, transversal, retrospectivo y descriptivo, sobre las publicaciones del IMSS de 1992 a 2011. Resultados. Se identificaron 881 investigaciones sobre calidad de la atención (11% IC95% 10.6-12.0) de 7 762 trabajos. Se publicaron 946 artículos (8.9% IC95% 8.4-9.5) relacionados con la calidad. Conclusiones. Se identificó interés en realizar investigación sobre calidad del servicio. Habrá que establecer cuál ha sido el impacto en la mejora de la atención, y su contribución a la toma de decisiones en materia de salud.


Objective. To identify studies on quality of health care in the IMSS. Materials and methods. A bibliometric, descriptive cross-sectional and retrospective study was conducted, from 1992 to 2011. Results. We identified 881 research studies related to the issue of quality (CI95% 10.6-12.0) of 7 762 studies presented at the annual research meetings. 10 521 articles were published in this period of time and only 946 (CI95% 8.4-9.5) were linked to the issue of quality. Conclusions. The results of this study allowed us to identify the interest about research on quality. Further research is needed to establish what has been the impact on the improvement of quality in health care.
