Prognostic role for the derived neutrophil-to-lymphocyte ratio in early breast cancer: a GEICAM/9906 substudy.

PURPOSE: Elevated markers of host inflammation, a hallmark of cancer, have been associated with worse outcomes in several solid tumors. Here, we explore the prognostic role of the derived neutrophil-to-lymphocyte ratio (dNLR), across different tumor subtypes, in patients with early breast cancer. PATIENTS AND METHODS: This was a retrospective analysis of 1246 patients with lymph node-positive, operable early breast cancer enrolled in the GEICAM/9906 trial, a multicenter randomized phase 3 study evaluating adjuvant chemotherapy. dNLR was calculated as the ratio of neutrophils and the difference between total leukocytes and neutrophils in peripheral blood before chemotherapy. Disease-free survival (DFS) and overall survival were explored using a Cox proportional hazard analysis. RESULTS: The analysis comprised 1243 (99.8%) patients with dNLR data, with a median follow-up of 10 years. Data on intrinsic subtypes were available from 818 (66%) patients (luminal A 34%, luminal B 32%, HER2-enriched 21% and basal-like 9%). Median dNLR was 1.35 [interquartile range (IQR) 1.08-1.71]. In the whole population, dNLR was not prognostic after adjustment for clinico-pathological factors. However, dNLR ≥ 1.35 was independently associated with worse DFS in the hormone receptor-negative/HER2+ population (HR 2.86; p = 0.038) and in patients with one to three lymph node metastases (HR 1.32, p = 0.032). There was a non-significant association with worse DFS in non-luminal and in HER2-enriched tumors (HR 1.40, p = 0.085 and HR 1.53, p = 0.067). No significant interaction was observed between the treatment arm and dNLR. CONCLUSION: Elevated dNLR appears to be an adverse prognostic factor in hormone receptor-negative early breast cancer.

Outcomes of single versus double hormone receptor-positive breast cancer. A GEICAM/9906 sub-study.

BACKGROUND: Retrospective data suggest better outcomes for patients with double hormonal receptor (oestrogen [ER] and progesterone receptor [PgR])-positive (dHR+) early breast cancer, compared with single hormonal receptor-positive, sHR+, (ER+/PgR- or ER-/PgR+) disease. Here, we evaluate the classification according to intrinsic subtypes and clinical outcomes of sHR+ versus dHR+ in HER2-negative breast cancer patients enrolled in GEICAM/9906 study (NCT00129922). METHODS: Archival tumours were retrieved retrospectively for the analysis of ER, PgR and HER2 status and classified into intrinsic subtypes using the PAM50 gene expression assay. Disease-free survival (DFS) and overall survival (OS) were explored using a Cox proportional hazard analysis. RESULTS: Data on intrinsic subtypes were available in 571 (50%) patients with ER+ and/or PR+, and HER2-negative primary tumours. The incidence of luminal A and luminal B subtypes were 52%/36% in dHR+ tumours (ER+/PgR+), and 15%/58% in ER+/PgR-tumours. ER-/PgR+ tumours were mainly luminal A (52%). Compared with ER+/PgR+ patients, DFS was similar in ER-/PgR+ (hazard ratio [HR] 1.15, 95% confidence interval [CI] 0.57-2.34, p = 0.70) but worse in ER+/PgR- patients (HR 1.60, 95% CI 1.12-2.28, p < 0.01). Similar results were observed for OS (HR 1.50, p = 0.30 and HR 1.86, p < 0.01, respectively). CONCLUSIONS: The ER+/PgR- group is characterised by higher proliferation and worse outcomes. In spite of the ER-/PgR+ subgroup resembles ER+/PgR+ disease in terms of molecular subtypes and outcomes, the small number of patients in this subgroup prevents from drawing any conclusions.

Renal cell carcinoma with vascular invasion: Mortality and prognostic factors. / Carcinoma de células renales con invasión vascular: mortalidad y factores pronósticos.

OBJECTIVE: Analysis of the results of patients who had been operated of renal cell carcinoma with vascular invasion in our institution, evaluation of prognostic factors and complications. METHODS: Retrospective observational study of 37 patients diagnosed of renal cell carcinoma with vascular invasion operated between May 1999 and July 2013. We used the method of Kaplan-Meier survival analysis and the Mantel-Haenszel's test (log rank) and the Cox's proportional hazards analysis test to analyse the risk factors of mortality. RESULTS: The median age was 60 years. Mean follow-up period was 42.1 months. The median overall survival and disease-free survival were 53.8and 36.3 months, respectively. There was statistical association between overall survival and ASA (p=0.047), tumor stage (p=0.003), lymph node involvement (p=0.024), presence of metastases (p=0.013), level of tumor thrombus (p=0, 05) and histological type (p=0.001). 14 patients had grade IIIb complications or higher according to the Clavien Dindo classification, the most frequent was bleeding. CONCLUSIONS: Renal cell carcinoma with vascular invasion is a disease with high rate of mortality. Surgery is a therapeutic option that can be curative. The number of complications is important. Survival is conditioned by the ASA, tumor stage, the level of tumor thrombus, lymph node involvement, metastasis and histological type.

Cost-effectiveness analysis in the treatment of heavy menstrual bleeding in Spain.

OBJECTIVE: To compare the effectiveness and costs associated with first-line medical treatments for chronic heavy menstrual bleeding (HMB) in Spain. STUDY DESIGN: A cost-effectiveness analysis was conducted comparing the levonorgestrel-releasing intrauterine system (LNG-IUS) with the estradiol valerate/dienogest multiphase oral contraceptive (E2V/DNG), combined oral contraceptives (COC) and progestins (PROG). Study patients were fertile women diagnosed with HMB who initially wished to remain fertile. A Markov model based on reported clinical data and the opinion of a panel of experts was used. The time horizon of the analysis was 5 years. The analysis was conducted from the perspective of the Spanish National Health System (NHS), discounting both costs (€ 2013) and future effects at an annual rate of 3%. One-way sensitivity analyses and probabilistic sensitivity analysis were performed to test the robustness of the results. RESULTS: In the analysis at 5 years, the LNG-IUS was associated with a gain of 0.67, 2.22, and 3.53 symptoms free months (SFM) compared with E2V/DNG, COC and PROG, respectively. LNG-IUS contributed more quality-adjusted life months (QALM) than the other treatment alternatives (+1.74 vs. E2V/DNG, +3.33 vs. COC +3.53 vs. PROG). First-line LNG-IUS treatment resulted in savings of € 583, € 988, and € 1891 vs. E2V/DNG, COC and PROG, respectively. These cost benefits, coupled with the greater clinical benefits in terms of SFM and QALM, show that LNG-IUS is the dominant option (less costly and more effective). CONCLUSION: LNG-IUS is the medical treatment of choice and cost-saving option for the control of HMB in Spain.

Peliosis hepatis due to disseminated tuberculosis in a patient with AIDS.

Peliosis hepatis is a rare histopathological entity of unknown etiology. We present a case of peliosis hepatis in a 44-year-old man with disseminated tuberculosis and acquired immunodeficiency syndrome. The diagnosis of peliosis hepatis was based on liver biopsy results which were suggestive of tuberculous etiology. Diagnosis of tuberculosis was confirmed by auramine stain, rRNA amplification and culture of Mycobacterium tuberculosis from synovial fluid of the elbow joint. The patient responded favourably to tuberculostatic treatment with four drugs and the early initiation of highly active antiretroviral therapy. Histopathological evidence of peliosis hepatis, without an obvious cause, makes it necessary to rule out tuberculosis, especially in the context of immunodeficiency diseases and immigrants from endemic areas.

Objectively measured physical activity and C-reactive protein: National Health and Nutrition Examination Survey 2003-2004.

The association between physical activity (PA) and C-reactive protein (CRP) is inconsistent, with nearly all studies using self-report measures of PA. The purpose of this study was to examine the association between objectively measured PA and CRP in US adults and children. Adults (N=2912) and children (N=1643) with valid accelerometer data and CRP data were included in the analyses. Logistic regression analysis was used to assess the odds of meeting PA guidelines across CRP quartiles for children and among adults with low, average, and high CRP levels. For adults, after adjustments for age, gender, race, body mass index, smoking, diabetes, and high-density lipoprotein cholesterol (HDL-C), compared with those with low CRP levels, odds ratios were 0.59 (CI=0.45-0.77) and 0.46 (CI=0.28-0.76) for participants with average and high CRP levels, respectively. For children, after adjustments for age, gender, race, weight status, and HDL-C, compared with those in CRP quartile 1, odds ratios were 0.96 (CI=0.5-1.84), 1.23 (CI=0.71-2.12), and 0.79 (CI=0.33-1.88) for participants in quartiles 2, 3, and 4, respectively. Objectively measured PA is inversely associated with CRP in adults, with PA not related to CRP in children.

The effect of vitamin D and frailty on mortality among non-institutionalized US older adults.

BACKGROUND/OBJECTIVES: Although both frailty and low vitamin D have been separately associated with an increased risk for adverse health, their joined effects on mortality have not been reported. The current study examined prospectively the effects of frailty and vitamin D status on mortality in US older adults. SUBJECTS/METHODS: Participants aged ≥ 60 years in The Third National Health and Nutrition Examination Survey with 12 years of mortality follow-up were included in the analysis (n=4731). Frailty was defined as meeting three or more criteria and pre-frailty as meeting one or two of the five frailty criteria (low body mass index (BMI), slow walking, weakness, exhaustion and low physical activity). Vitamin D status was assessed by serum 25-hydroxyvitamin D (25(OH)D) and categorized into quartiles. Analyses were adjusted for gender, race, age, smoking, education, latitude and other comorbid conditions. RESULTS: Serum 25(OH)D concentrations were lowest in participants with frailty, intermediate in participants with pre-frailty and highest in participants without frailty. The odds of frailty in the lowest quartile of serum 25(OH)D was 1.94 times the odds in the highest quartile (95% confidence interval (CI): 1.09-3.44). Mortality was positively associated with frailty, with the risk among participants who were frail and had low serum 25(OH)D being significantly higher than those who were not frail and who had high concentrations of serum 25(OH)D (hazards ratio 2.98; 95% CI: 2.01-4.42). CONCLUSION: Our results suggest that low serum 25(OH)D is associated with frailty, and there is additive joint effects of serum 25(OH)D and frailty on all-cause mortality in older adults.

Body mass index and mortality rate among Hispanic adults: a pooled analysis of multiple epidemiologic data sets.

OBJECTIVE: To evaluate the association between body mass index (BMI, kg m⁻²) and mortality rate among Hispanic adults. METHODS AND PROCEDURES: Analysis of five data sets (total N=16,798) identified after searching for publicly available, prospective cohort data sets containing relevant information for at least 500 Hispanic respondents (≥18 years at baseline), at least 5 years of mortality follow-up, and measured height and weight. Data sets included the third National Health and Nutrition Examination Survey, the Puerto Rico Heart Health Program (PRHHP), the Hispanic Established Population for Epidemiologic Studies of the Elderly (HEPESE), the San Antonio Heart Study (SAHS) and the Sacramento Area Latino Study on Aging. RESULTS: Cox proportional hazards regression models, adjusting for sex and smoking, were fit within three attained-age strata (18 to younger than 60 years, 60 to younger than 70 years, and 70 years and older). We found that underweight was associated with elevated mortality rate for all age groups in the PRHHP (hazard ratios [HRs]=1.38-1.60) and the SAHS (HRs=1.88-2.51). Overweight (HRs=0.38 and 0.84) and obesity grade 2-3 (HRs=0.75 and 0.60) associated with reduced mortality rate in the HEPESE dataset for those in the 60 to younger than 70 years, and 70 years and older attained-age strata. Weighted estimates combining the HRs across the data sets revealed a similar pattern. CONCLUSION: Among Hispanic adults, there was no clear evidence that overweight and obesity associate with elevated mortality rate.

[Incidence of childhood cancer in the autonomous region of Castilla y León in Spain (2003-2007)]. / Incidencia del cáncer infantil en la Comunidad de Castilla y León (2003-2007).

BACKGROUND: Since 1980, childhood cancer cases have been registered in Spain in the National Registry of Childhood Cancer (based on hospital cases) and since 1990, five autonomous regions have had a population based registry. There is no specific registry of childhood cancer in Castilla y Leon. OBJECTIVES: Our aim was to estimate the childhood cancer incidence in the autonomous region of Castilla y Leon and to assess the usefulness of the computerised diagnosis of hospital discharges as a source of data in a potential autonomous region population based registry. METHODS: We included patients younger than 15 years old who were diagnosed, for the first time, of cancer during the years 2003-2007. The information collected was obtained through the Minimum Basic Data Set (MBDS) of the public hospitals in the autonomous region of Castilla y Leon. RESULTS: In this period of 5 years (2003-2007), 220 cases of childhood cancer had been reported. The most frequent cancer detected was leukaemia (28.6%) followed by the central nervous system tumours (19.5%) and lymphoma (15.9%). The overall rate of childhood cancer incidence was 152.8 cases per million children. The diagnostics codes did not allow tumours to be classified by their histological type in 74 cases (33.6%). CONCLUSIONS: The overall incidence by diagnostic groups of childhood cancer in the autonomous region of Castilla y Leon was similar to those reported by other national and international registries. In a Cancer registry the MBDS could be useful as a data source in the capture of new cases, but in a high percentage of cases it does not allow tumours to be classified by their histological type.

Effects of chronic fluoxetine treatment on the rat somatosensory cortex: activation and induction of neuronal structural plasticity.

Recent hypotheses support the idea that disruption of normal neuronal plasticity mechanisms underlies depression and other psychiatric disorders, and that antidepressant treatment may counteract these changes. In a previous report we found that chronic fluoxetine treatment increases the expression of the polysialylated form of the neural cell adhesion molecule (PSA-NCAM), a molecule involved in neuronal structural plasticity, in the somatosensory cortex. In the present study we intended to find whether, in fact, cell activation and neuronal structural remodeling occur in parallel to changes in the expression of this molecule. Using immunohistochemistry, we found that chronic fluoxetine treatment caused an increase in the expression of the early expression gene c-fos. Golgi staining revealed that this treatment also increased spine density in the principal apical dendrite of pyramidal neurons. These results indicate that, apart from the medial prefrontal cortex or the hippocampus, other cortical regions can respond to chronic antidepressant treatment undergoing neuronal structural plasticity.

Coffee intake and risk of incident diabetes in Puerto Rican men: results from the Puerto Rico Heart Health Program.

OBJECTIVE: To study prospectively the association of coffee intake with incident diabetes in the Puerto Rico Heart Health Program cohort, comprising 9824 middle-aged men (aged 35-79 years). METHODS: Of 9824 men, 3869 did not provide a fasting blood sample at baseline, 1095 had prevalent diabetes and 131 were not given fasting glucose tests at any subsequent study visit. Thus, the present analysis includes 4685 participants. Diabetes was ascertained at baseline and at two study visits between 1968 and 1975 using fasting glucose tests and self-reports of physician-diagnosed diabetes or use of insulin or hypoglycaemic medication. Logistic regression analysis was used to assess the association of coffee intake with risk of incident diabetes while adjusting for covariates (age, BMI, physical activity, smoking, education, alcohol intake, family history of diabetes, intakes of milk and sugar). RESULTS: Five hundred and nineteen participants met the criteria for incident diabetes. Compared with those reporting intake of 1-2 servings of coffee/d, coffee abstainers were at reduced risk (OR = 0.64; 95 % CI 0.43, 0.94). Among coffee drinkers, there was a significant trend of decreasing risk by intake (P = 0.02); intake of >/=4 servings/d was associated with an odds ratio of 0.75 (95 % CI 0.58, 0.97). CONCLUSIONS: Study findings support a protective effect of coffee intake on diabetes risk, while also suggesting that abstainers may be at reduced risk.

Thoracic epidural anesthesia decreases C-reactive protein levels in patients undergoing elective coronary artery bypass graft surgery with cardiopulmonary bypass.

BACKGROUND: Coronary artery bypass graft surgery with cardiopulmonary bypass induces a systemic inflammatory response. However, when thoracic epidural anaesthesia is administered as part of a combined anesthetic technique, the stress response associated with the cardiopulmonary bypass (CPB) may be attenuated. METHODS: Twenty-two patients undergoing elective coronary artery bypass graft surgery were randomized to receive either balanced general anesthesia with 7-20 microg/kg fentanyl (GA group) or combined anesthesia with 3-6 microg/kg fentanyl and an epidural bolus of 0.33% bupivacaine followed by a continuous perfusion of 0.175% bupivacaine, which was continued up to 48 hours after surgery (TEA group). The hemodynamic levels, troponin I, C-reactive protein (CRP), fibrinogen, leukocyte and platelet counts were recorded preoperatively, and 5 h, 16 h, 24 h, and 36 h after termination of the cardiopulmonary bypass. The time to tracheal extubation and cardiopulmonary complication rate were measured postoperatively. Data were analyzed with the Student's t and Mann Whitney tests, as appropriate. Differences were considered significant at P<0.05. RESULTS: All parameters significantly increased following CPB. The increase in CRP levels were lower in the TEA group at 16 hours (P=0.048). The increase of fibrinogen levels were lower in the TEA group at 24 hours (P=0.047). No differences were found in troponin levels between groups during the study. No significant differences were observed in extubation times (GA group 750+/-144 min; TEA group 702+/-451 min). CONCLUSION: Thoracic epidural anaesthesia, as a part of a combined anesthetic technique, attenuated the inflammatory response (CRP and fibrinogen levels) to cardiac surgery with cardiopulmonary bypass. However, this effect was not reflected in a decrease of troponin I levels, reduced incidence of complications, or in an earlier extubation time.

Analysis of CXCL12 3'UTR G>A polymorphism in colorectal cancer.

Colorectal cancer is one of the most prevalent cancers in developed countries. However, the genetic factors influencing its appearance remain far from being fully characterized. Recently, a G>A functional transition mapping the 3' untranslated region of the CXCL12 gene (rs1801157) has been found to be under-represented among rectal cancer patients when compared to colon cancer patients from a Swedish series. Here we present the results from an independent analysis of CXCL12 rs1801157 in a larger CRC series of Spanish origin in order to analyse the robustness of this association within a different European population. No significant difference was observed between controls and colon or rectal cancer patients. We were also unable to find a correlation between rs1801157 and different prognostic markers such as metastasis development or disease-free survival time. The epidemiologic data involving CXCL12 rs1801157 in colorectal cancer risk are discussed.

[Effect of tranexamic acid on postoperative bleeding in pediatric heart surgery]. / Efecto del ácido tranexáimico en el sangrado postoperatorio de cirugía cardiaca en pediatría.

OBJECTIVE: To assess the effects of a single dose of tranexamic acid on bleeding and requirement for blood product transfusion in children undergoing cardiac surgery with cardiopulmonary bypass. PATIENTS AND METHODS: A prospective study of closed cohorts undergoing pediatric heart surgery was carried out. The children weighed between 4 and 10 kg. Reoperated and cyanotic patients were included in the sample. The treatment group received 50 mg x kg(-1) of tranexamic acid before surgery. Analyzed data collected during the first 24 hours after surgery were biochemical parameters, bleeding, use of blood products, and D-dimer levels. RESULTS: Fifty-three patients, 25 in the treatment group, were enrolled. Patients on treatment had 24.8% less bleeding in the first 24 hours after surgery (P = .02). The transfusion of blood products was 20% less in the treatment group, although the difference was not significant except in the subgroup of patients who were reoperated. In that group the amount of blood products transfused was 72% less than in the control group (P = .05). D-dimer levels were also lower in the treatment group (P = .003). No adverse effects attributable to the treatment were observed. CONCLUSIONS: A single preoperative dose of tranexamic acid to inhibit fibrinolysis reduces bleeding 24.8% in pediatric patients undergoing heart surgery with cardiopulmonary bypass. The effect is greater in reoperated patients, leading to a reduction in their requirement for transfusion. The use of this therapy in these patients is therefore highly justified.

Chronic antidepressant treatment induces contrasting patterns of synaptophysin and PSA-NCAM expression in different regions of the adult rat telencephalon.

Structural modifications occur in the brain of severely depressed patients and they can be reversed by antidepressant treatment. Some of these changes do not occur in the same direction in different regions, such as the medial prefrontal cortex, the hippocampus or the amygdala. Differential structural plasticity also occurs in animal models of depression and it is also prevented by antidepressants. In order to know whether chronic fluoxetine treatment induces differential neuronal structural plasticity in rats, we have analyzed the expression of synaptophysin, a protein considered a marker of synaptic density, and the expression of the polysialylated form of the neural cell adhesion molecule (PSA-NCAM), a molecule involved in neurite and synaptic remodeling. Chronic fluoxetine treatment increases synaptophysin and PSA-NCAM expression in the medial prefrontal cortex and decreases them in the amygdala. The expression of these molecules is also affected in the entorhinal, the visual and the somatosensory cortices.

Solid sampling-graphite furnace atomic absorption spectrometry for the direct determination of silver at trace and ultratrace levels.

In this work, the possibilities of solid sampling-graphite furnace atomic absorption spectrometry for the direct determination of silver in solid samples of very different nature (a biological sample, a soil, an ore concentrate and a polymer) and showing substantial differences in their analyte content (from approximately, 40 ng g(-1) up to 350 microg g(-1)) have been evaluated, the goal always being to develop fast methods, only relying on the use of aqueous standards for calibration. Different factors had to be taken into account in order to develop suitable procedures for all the samples under investigation. Among the most important ones, the following can be mentioned: (i) optimization of the temperature program in order to selectively atomize the analyte; (ii) the use of chemical modifiers (such as Pd or HNO3), depending on the sample characteristics; (iii) appropriate wavelength, argon flow and sample mass selection (depending on the analyte content); (iv) the use of 3-field mode Zeeman-effect background correction in order to further expand the linear range up to 1000 ng of Ag, which was needed for analysis of the sample showing the highest Ag content (polypropylene). The procedures finally proposed show interesting features for the determination of silver in solid samples: the advantage of using aqueous standard solutions for calibration, a high sample throughput (approximately, 15 min per sample), a low detection limit (2 ng g(-1)), sufficient precision (R.S.D. values in the vicinity of 10%) and a reduced risk of analyte losses and contamination.

PSA-NCAM expression in the rat medial prefrontal cortex.

The rat medial prefrontal cortex, an area considered homologous to the human prefrontal cortex, is a region in which neuronal structural plasticity has been described during adulthood. Some plastic processes such as neurite outgrowth and synaptogenesis are known to be regulated by the polysialylated form of the neural cell adhesion molecule (PSA-NCAM). Since PSA-NCAM is present in regions of the adult CNS which are undergoing structural remodeling, such as the hypothalamus or the hippocampus, we have analyzed the expression of this molecule in the medial prefrontal cortex of adult rats using immunohistochemistry. PSA-NCAM immunoreactivity was found both in cell bodies and in the neuropil of the three divisions of the medial prefrontal cortex. All cell somata expressing PSA-NCAM corresponded to neurons and 5' bromodeoxyuridine labeling after long survival times demonstrated that these neurons were not recently generated. Many of these PSA-NCAM immunoreactive neurons in the medial prefrontal cortex could be classified as interneurons on the basis of their morphology and glutamate decarboxylase, isoform 67 expression. Some of the PSA-NCAM immunoreactive neurons also expressed somatostatin, neuropeptide Y and calbindin-D28K. By contrast, pyramidal neurons in this cortical region did not appear to express PSA-NCAM. However, some of these principal neurons appeared surrounded by PSA-NCAM immunoreactive puncta. Some of these puncta co-expressed synaptophysin, suggesting the presence of synapses. Since the etiology of some psychiatric disorders has been related to alterations in medial prefrontal cortex structural plasticity, the study of PSA-NCAM expression in this region may open a new approach to the pathophysiology of these mental disorders.

Solitary fibrous tumor arising in the fallopian tube.

BACKGROUND: Solitary fibrous tumor (SFT) is an uncommon neoplasm that usually arises in the pleura. Although this tumor has been described at other sites, in the female genital tract it is extremely uncommon. CASE: We present a case of solitary fibrous tumor arising in the fallopian tube. A 32-year-old woman who presented with acute flank pain had a presumptive diagnosis of leiomyoma of the fallopian tube after abdominopelvic ultrasound. The adnexal mass was excised laparoscopically. Histologic examination showed the characteristic features of a solitary fibrous tumor. CONCLUSION: Although rare, the diagnosis of solitary fibrous tumor can be considered in the differential diagnosis of adnexal masses.
