RESUMEN

BACKGROUND: The aim of this prospective study was to evaluate the role of serum IL-6 as a potential predictive biomarker of postoperative complications (POC) in elective colorectal surgery. METHOD: A total of 115 patients underwent colorectal surgery for malignancy. IL-6 was measured on the first and third postoperative days (POD1, POD3), and C-reactive protein (CRP) was measured on the POD3. POC was analysed in subgroups according to Clavien‒Dindo (CD), antibiotic (ATB) treatment, intensive care unit (ICU) and hospital length of stay. The predictive power of variables for evaluated endpoints was analysed using receiver-operating characteristic (ROC) analysis and described by area under the curve (AUC). ROC analysis was adopted for the identification of optimal cut-offs. Histological analysis was performed to verify IL-6 production by the tumour. RESULTS: Out of 115 patients who were analysed, 42% had POC. Patients with POC had significantly higher serum levels of IL-6 on POD1 (p < 0.001) and POD3 (p < 0.001). IL-6 early on POD1 as a predictor of antibiotic treatment, ICU stay and hospital stay (AUC 0.818; 0.811; 0.771) did not significantly differ from the AUC of CRP late on POD3 (0.879; 0.838, 0.752). A cut-off IL-6 value of 113 pg/ml on POD1 and 180.5 pg/ml on POD3 in severe complications (CD > 3a) resulted in 75% and 72% sensitivity, 78.6% and 99% specificity, negative predictive value 96.4% and 97% and positive predictive value 29% and 88.9%. CONCLUSION: The serum level of interleukin-6 can predict severe (CD > 3a) POC early on POD1. On POD3, IL-6 is superior to CRP in terms of high positive predictive power of severe POC. Interestingly, the advantage of IL-6 on POD1 is early prediction of the need for antibiotic treatment, ICU stay and hospital stay, which is comparable to the CRP serum level late on the third POD.

RESUMEN

OBJECTIVES: This study examined the prognostic significance of breast cancer patients characteristics (coping strategies, BMI, age) and disease characteristics (stage of disease, relapse) with respect to quality of life (QoL) following treatment.Sample and settings: 120 breast cancer patients following treatment were recruited. Health-related QoL was assessed using the Czech version of FACT-B and SF-36; additionally, we used a life satisfaction questionnaire. Coping strategies were assessed using the SVF-78 method. In our sample of women, the average time from diagnosis to start of the study was 5.3 years. STATISTICAL ANALYSIS: Factors influencing QoL after treatment were analysed with univariate and multivariate linear regression. RESULTS: Overall negative strategy defined in SVF-78 (Flight tendency, Resignation and Self-accusation) was found to be associated with lower scores of most components of used QoL methods, while Resignation was found as the most negatively influencing strategy. Active problem confrontation (Situation control and Positive self-instruction) was associated with better QoL. More advanced stages and recurrence were related to a significant decrease in QoL for certain components only. CONCLUSION: Our findings suggest a significant predictive power of disease-related factors and of patients characteristics including coping strategies for QoL following treatment in Czech breast cancer survivors.Key words: breast cancer survivors - coping strategy - linear regression model - quality of life prediction - resignation.

RESUMEN

INTRODUCTION: After spinal cord injury (SCI), individuals are typically considered by the general public to be asexual. Handicapped women have more problems with socio-sexual adaptation, stemming from low self-confidence, low self-esteem, and the absence of spontaneity. AIMS: To determine changes in the sexual lives of women after SCI. METHODS: A self-constructed questionnaire was used to map sexual function after SCI. We retrospectively compared sexual function in 30 women with SCI with that in 30 without SCI who led an active sexual life. Descriptive and inductive statistics were applied using the Student paired and non-paired t-tests and the Levene test. MAIN OUTCOME MEASURES: The main variables were presence vs absence of sexual dysfunction in a group of women after SCI and a comparison of the incidence of sexual dysfunctions in women after SCI with that of a control group. RESULTS: A significant difference was ascertained in women with SCI in sexual desire (P < .001), lubrication (P < .001), and reaching orgasm before and after injury (P = .030). A comparison of the two groups showed a significant difference in the realization of coital sexual activity (P < .001), erotogenous zones of the mouth (P = .016), nipples (P = .022), and genitals (P < .001), and in the ability to reach orgasm (P = .033). The negative impact of incontinence on the sexual life of women with SCI proved significant (P < .001). Negative factors for sexual activity in women with SCI were lower sensitivity in 16 (53%), spasms and mobility problems in 12 (40%), lower desire in 11 (36%), pain in 4 (13%), and a less accommodating partner in 3 (10%). CONCLUSION: Intercourse was the preferred sexual activity in women with SCI. Compared with the period before injury, there was significant lowering of sexual desire, impaired lubrication, and orgasmic ability after SCI. A comparison of the two groups showed a difference in erotogenous zones and in reaching orgasm. Sramkova T, Skrivanova K, Dolan I, et al. Women's Sex Life After Spinal Cord Injury.

RESUMEN

The present study investigates the photochemical properties of a potential photosensitiser, indocyanine green (ICG), in an in vitro HeLa cell system. Cell proliferation was studied after a combined effect of ICG, at a concentration range of 24-94 microM, and therapeutic laser irradiation at several different energy densities. In addition, ICG cytotoxicity was evaluated in HeLa cells and V79 Chinese hamster by the MTT assay. Phototoxicity was evaluated at 1, 24, and 48 h after irradiation. No phototoxic effect was detected 1h after irradiation. The maximum phototoxic effect of ICG on HeLa cells was detected for an ICG concentration of 94 microM, a laser output of 360 mW, and an energy density of 99 J/cm(2) at 24h after irradiation. Potentiation of the ICG phototoxic effect was achieved by adding 20 microM H(2)O(2), which was a non-toxic concentration for HeLa cells in this experimental design. At 48 h after laser irradiation a statistically significant difference was found between the toxicity of ICG plus peroxide, as compared to ICG alone. The addition of H(2)O(2) at a concentration of 20 microM caused a significant increase in phototoxicity of ICG for HeLa cells. Our results confirm that ICG could be a perspective agent for use in photodynamic therapy and that its phototoxic effect can be potentiated by addition of an oxidative agent.
