RESUMO

INTRODUCTION: High-dose methotrexate (HDMTX) is administered for the treatment of some cancers. HDMTX is usually safe but may crystallize in renal tubules causing acute kidney injury (AKI). Consequently, MTX elimination is delayed, resulting in a severe and life-threatening condition. No studies have been published about the impact of MTX toxicity in Spain. This study aims to estimate the incidence and management of MTX delayed elimination and toxicity. METHODS: A two-round Delphi study was performed to reach consensus between 10 medical experts on haemato-oncology and paediatric oncology with experience in the management of HDMTX treated patients from leading Spanish hospitals. An online questionnaire was developed based on national and international guidelines and previous evidence regarding HDMTX-related toxicity. Consensus was established at 80% agreement. Median and interquartile ranges were calculated, and incidence data were extrapolated to the Spanish general population. RESULTS: Out of 1.475 patients estimated to receive HDMTX treatment annually in Spain, 27.5% present MTX delayed elimination and 11.6% develop HDMTX-induced AKI (35.4% with severe systemic toxicities (>grade 3) and 18.8% develop chronic renal disease). Mortality is estimated in 4.2%. Immuno-enzymatic assay is used in most of the hospitals (90%) for MTX serum level monitoring. All experts use increased supportive care and high leucovorin as first-line treatment. Available treatments in experts' hospitals in case toxicity persists are haemodialysis (90% of hospitals), glucarpidase (60%) and hemofiltration (50%). Most prevalent non-renal systemic toxicities are haematologic and mucositis (21-40% of patients). Patients with HDMTX-induced AKI require from intensive care (5% of patients), more than 3 sessions and 4 days of dialysis, and about 8.5 days of hospitalization (non-ICU patients) and 12 days in case of patients requiring ICU. CONCLUSIONS: These results are the first evidence regarding HDMTX-induced AKI in Spain. Incidence and mortality results are in line with previous studies. Clinical management is based on preventive measures and the treatment depend on the availability in the hospital. The need for effective, safe and rapid treatment for the reduction of MTX toxic levels and the improvement of monitoring methods were noted by experts as urgent needs. Further observational studies to validate these results would be needed.

RESUMO

A hydrocoele surgery facility assessment tool (HSFAT) was developed to assess the readiness of hydrocoele surgery services in health facilities prior to implementation of hydrocoele surgical campaigns for the elimination of lymphatic filariasis (LF). A first version of the tool was piloted in Bangladesh, Malawi and Nepal in 2019, then, following feedback from country programme managers, a second version of the tool was rolled out across countries implementing hydrocoele surgery in the Accelerating the Control of Neglected Tropical Diseases (Ascend) West and Central Africa Programme, including Benin, Burkina Faso, Ghana, Guinea, Niger and Nigeria. The HSFAT assessed facilities across 10 domains: background information, essential amenities, emergency patient transfer, laboratory capacity, surgical procedures and trained staff, infection prevention, non-disposable basic equipment, disposable basic equipment, essential medicines and current hydrocoele practices. The HSFAT results highlight key areas for improvement in different countries and can be used to develop a quality improvement plan, which may include actions with agreed deadlines to improve the readiness and quality of hydrocoele surgery services provided by the health facility, prior to implementation of surgical campaigns and assist country programmes to achieve the dossier requirements set out by the World Health Organization for the elimination of LF.

RESUMO

PURPOSE: Several frameworks have been developed to define and quantify the value of oncologic therapies and to support decision making; however, they define treatment value mainly in terms of clinical benefit. As part of its mission to improve oncologic care, the ECO Foundation (Excellence and Quality in Oncology) directed this pilot study aimed at developing a reflective multicriteria decision analysis (MCDA)-based framework for evaluating and positioning oncologic drugs in the clinical setting. METHODS: The framework was developed following Evidence and Value: Impact on Decision-Making methodology, and literature was reviewed to identify relevant criteria. The selected criteria were then presented to a group of experts composed of 9 clinical oncologists who assessed each criterion for inclusion in the framework and suggested modifications in their definition and/or response scale. The framework was tested in 2 case studies (abemaciclib for advanced or metastatic hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer and TAS-102 for metastatic colorectal cancer) to validate the proposed framework; this was followed by a discussion of the results. RESULTS: Eight of the 15 criteria presented to the experts were included in the framework: disease severity, unmet needs, comparative efficacy, comparative safety/tolerability, treatment intent, comparative treatment cost, comparative other medical costs, and quality of evidence. Framework validation in 2 drug cases resulted in similar value scores, although they were based on different contributing criteria and resulted in different clinical recommendations. CONCLUSION: We developed and validated a reflective MCDA framework for the assessment and positioning of oncologic therapies in Spain. Additional work is needed to create a manual for practical decision making in the clinical setting.

RESUMO

OBJECTIVE: There are differences between countries regarding data requirements for orphan drug evaluation and it  is also unknown which criteria might determine the price and reimbursement decision. This study aimed to identify the key  criteria for price and reimbursement of orphan drugs in Spain, approved by the European Commission, between January 2012 and June 2018. METHOD: A descriptive analysis of the orphan drugs and its characteristics was performed. Outcomes criteria assessed  were: therapeutic area, existence of alternative treatment, rarity of the disease, clinical trial outcomes and therapeutic  positioning report assessment. Hypotheses for each variable regarding Spanish pricing and reimbursement were made  and tested with two regression analyses. RESULTS: Out of 78 orphan drugs approved by the European Commission, 82.1% asked pricing and reimbursement in  Spain. From this, 43.8% had pricing and reimbursement approved and 20.3% rejected. Mean time from Spanish  marketing authorisation approval to pricing and reimbursement approval was 12.1 ± 5.1 months. Having a positive  therapeutic positioning report and no therapeutic alternatives would be associated with a positive pricing and  reimbursement in Spain. CONCLUSIONS: It remains challenging to establish which are the driving criteria for pricing and reimbursement approval  of orphan drugs in Spain. Further research should be done including other variables that might influence the pricing and  reimbursement final decision in Spain.


Objetivo: Los requisitos para la evaluación de los medicamentos huérfanos difieren entre los países  miembros de la Unión Europea y tampoco se sabe qué criterios influyen en la decisión final sobre  precio y financiación. Este estudio ha tenido como objetivo identificar los criterios clave para establecer el precio y la financiación de los medicamentos huérfanos en España, una vez  aprobados por la Comisión Europea, entre enero de 2012 hasta junio de 2018.Método: Se realizó un análisis descriptivo de los medicamentos huérfanos y sus características. Los  criterios evaluados fueron: área terapéutica, existencia de tratamientos alternativos, rareza de la  enfermedad, tipo de resultados de los ensayos clínicos e informe de posicionamiento terapéutico. Para  cada variable se estableció una hipótesis con respecto a la aprobación de precio y  financiación y se analizaron con dos análisis de regresión.Resultados: De las 78 aprobaciones de medicamentos huérfanos realizadas por la Comisión Europea,  el 82,1% solicitaron precio y financiación en España. De estas, el 43,8% fueron aprobadas  y el 20,3% fueron rechazadas. El tiempo medio desde la aprobación de la autorización de comercialización en España hasta la aprobación del precio y la financiación fue de 12,1 ± 5,1  meses. Un informe de posicionamiento positivo y la falta de alternativas terapéuticas se asociaría con  una aprobación de precio y financiación.Conclusiones: Sigue siendo un reto establecer cuáles son los criterios clave para la aprobación de los  medicamentos huérfanos en España. Los próximos estudios deberían incluir un mayor número de  variables que puedan influir en el precio y la decisión de financiación.

RESUMO

OBJECTIVES: Patient involvement in drug evaluation decision making is increasing. The aim of the current study was to develop a multi-criteria decision analysis (MCDA) framework that would enable the inclusion of the patient perspective in the selection of appropriate criteria for MCDAs being used in the value assessments of oncologic drugs. METHODS: A literature review was conducted to identify and define criteria used in drug assessments from patient perspectives. The Evidence and Value: Impact on Decision Making methodology was used to develop a MCDA framework. Identified criteria were discussed by a sample of oncology patient association representatives who decided which criteria were important from patient perspectives. Selected criteria were rated by importance. The preliminary MCDA framework was tested through the assessment of a hypothetical oncology treatment. A discussion was carried out to agree on a final pilot MCDA framework. RESULTS: Twenty-two criteria were extracted from the literature review. After criteria discussion, sixteen criteria remained. The most important criteria were comparative patient reported outcomes (PRO), comparative efficacy and disease severity. After the discussion generated by the scoring of the hypothetical oncology treatment, the final pilot MCDA framework included seven quantitative criteria ("disease severity", "unmet needs", "comparative efficacy / effectiveness", "comparative safety / tolerability", "comparative PROs", "contribution of oncological innovation") and one contextual criterion ("population priorities and access"). CONCLUSIONS: The present study developed a pilot reflective MCDA framework that could increase patient's capability to participate in the decision-making process by providing systematic drug assessments from the patient perspective.

RESUMO

PURPOSE: Despite availability of multimodal treatment options for acromegaly, achievement of long-term disease control is suboptimal in a significant number of patients. Furthermore, disease control as defined by biochemical normalization may not always show concordance with disease-related symptoms or patient's perceived quality of life. We developed and validated a tool to measure disease activity in acromegaly to support decision-making in clinical practice. METHODS: An international expert panel (n = 10) convened to define the most critical indicators of disease activity. Patient scenarios were constructed based on these chosen parameters. Subsequently, a panel of 21 renowned endocrinologists at pituitary centers (Europe and Canada) categorized each scenario as stable, mild, or significant disease activity in an online validation study. RESULTS: From expert opinion, five parameters emerged as the best overall indicators to evaluate disease activity: insulin-like growth factor I (IGF-I) level, tumor status, presence of comorbidities (cardiovascular disease, diabetes, sleep apnea), symptoms, and health-related quality of life. In the validation study, IGF-I and tumor status became the predominant parameters selected for classification of patients with moderate or severe disease activity. If IGF-I level was ≤1.2x upper limit of normal and tumor size not significantly increased, the remaining three parameters contributed to the decision in a compensatory manner. CONCLUSION: The validation study underlined IGF-I and tumor status for routine clinical decision-making, whereas patient-oriented outcome measures received less medical attention. An Acromegaly Disease Activity Tool (ACRODAT) is in development that might assist clinicians towards a more holistic approach to patient management in acromegaly.

RESUMO

BACKGROUND: The objective of the study was to reveal through pragmatic MCDA (EVIDEM) the contribution of a broad range of criteria to the value of the orphan drug lenvatinib for radioiodine refractory differentiated thyroid cancer (RR-DTC) in country-specific contexts. METHODS: The study was designed to enable comprehensive appraisal (12 quantitative, 7 qualitative criteria) in the current disease context (watchful waiting, sorafenib) of France, Italy and Spain. Data on the value of lenvatinib was collected from diverse stakeholders during country-specific panels and included: criteria weights (individual and social values); performance scores (judgments on evidence-collected through MCDA systematic review); qualitative impacts of contextual criteria; and verbal and written insights structured by criteria. The value contribution of each criterion was calculated and uncertainty explored. RESULTS: Comparative effectiveness, Quality of evidence (Spain and Italy) and Disease severity (France) received the greatest weights. Four criteria contributed most to the value of lenvatinib, reflecting its superior Comparative effectiveness (16-22% of value), the severity of RR-DTC (16-22%), significant unmet needs (14-21%) and robust evidence (14-20%). Contributions varied by comparator, country and individuals, highlighting the importance of context and consultation. Results were reproducible at the group level. Impacts of contextual criteria varied across countries reflecting different health systems and cultural backgrounds. The MCDA process promoted sharing stakeholders' knowledge on lenvatinib and insights on context. CONCLUSIONS: The value of lenvatinib was consistently positive across diverse therapeutic contexts. MCDA identified the aspects contributing most to value, revealed rich contextual insights, and helped participants express and explicitly tackle ethical trade-offs inherent to balanced appraisal and decisionmaking.

RESUMO

Available disease-specific questionnaires like the Acromegaly Quality of Life questionnaire have confirmed that quality of life (QoL) is impaired in acromegaly, especially in active disease. Successful therapy improves QoL, but it may not normalize completely even after endocrine cure; furthermore, there is not always a correlation between growth hormone (GH) and insulin-like growth factor 1 and subjective health perception of QoL. Appearance is the dimension most affected and has the highest impact on the patient's QoL. Worse QoL is associated with the presence of musculoskeletal pain, headache (if only medical therapy, not surgery, has been provided), having required treatment with radiotherapy, being older, of female gender, with a longer disease duration, coexisting diabetes mellitus, a higher BMI or becoming GH deficient after treatment for acromegaly.

RESUMO

Structural characterization of the human Y4 receptor (hY4R) interaction with human pancreatic polypeptide (hPP) is crucial, not only for understanding its biological function but also for testing treatment strategies for obesity that target this interaction. Here, the interaction of receptor mutants with pancreatic polypeptide analogs was studied through double-cycle mutagenesis. To guide mutagenesis and interpret results, a three-dimensional comparative model of the hY4R-hPP complex was constructed based on all available class A G protein-coupled receptor crystal structures and refined using experimental data. Our study reveals that residues of the hPP and the hY4R form a complex network consisting of ionic interactions, hydrophobic interactions, and hydrogen binding. Residues Tyr(2.64), Asp(2.68), Asn(6.55), Asn(7.32), and Phe(7.35) of Y4R are found to be important in receptor activation by hPP. Specifically, Tyr(2.64) interacts with Tyr(27) of hPP through hydrophobic contacts. Asn(7.32) is affected by modifications on position Arg(33) of hPP, suggesting a hydrogen bond between these two residues. Likewise, we find that Phe(7.35) is affected by modifications of hPP at positions 33 and 36, indicating interactions between these three amino acids. Taken together, we demonstrate that the top of transmembrane helix 2 (TM2) and the top of transmembrane helices 6 and 7 (TM6-TM7) form the core of the peptide binding pocket. These findings will contribute to the rational design of ligands that bind the receptor more effectively to produce an enhanced agonistic or antagonistic effect.

RESUMO

Mutagenic investigations of expressed membrane proteins are routine, but the variety of modifications is limited by the twenty canonical amino acids. We describe an easy and effective cysteine substitution mutagenesis method to modify and investigate distinct amino acids in vitro. The approach combines the substituted cysteine accessibility method (SCAM) with a functional signal transduction readout system using different thiol-specific reagents. We applied this approach to the prolactin-releasing peptide receptor (PrRPR) to facilitate biochemical structure-activity relationship studies of eight crucial positions. Especially for D(6.59)C, the treatment with the positively charged methanethiosulfonate (MTS) ethylammonium led to an induced basal activity, whereas the coupling of the negatively charged MTS ethylsulfonate nearly reconstituted full activity, obviously by mimicking the wild-type charged side chain. At E(5.26)C, W(5.28)C, Y(5.38)C, and Q(7.35)C, accessibility was observed but hindered transfer into the active receptor conformation. Accordingly, the combination of SCAM and signaling assay is feasible and can be adapted to other G-protein-coupled receptors (GPCRs). This method circumvents the laborious way of inserting non-proteinogenic amino acids to investigate activity and ligand binding, with rising numbers of MTS reagents allowing selective side chain modification. This method pinpoints to residues being accessible but also presents potential molecular positions to investigate the global conformation.

RESUMO

BACKGROUND: Cushing's disease (CD) is a rare disorder of chronic hypercortisolism due to an adrenocorticotropic hormone (ACTH)-secreting pituitary corticotroph adenoma. Because hypercortisolism symptoms are wide ranging, it is important to assess a variety of outcomes including both clinical factors, such as cortisol levels, and health-related quality of life (HR-QOL), to better understand the severity and impact of CD on patients and the potential efficacy of CD treatment. Pasireotide, a somatostatin analog that targets somatostatin receptors on the pituitary adenoma, is under development as a treatment for CD. A phase III clinical trial was conducted to investigate its safety and efficacy in patients with CD. In this trial, HR-QOL was assessed with the Cushing's Quality-of-Life (CushingQOL) questionnaire, specifically developed and validated in patients with Cushing's syndrome. OBJECTIVE: Reliability, validity, the ability to detect change, and a minimal important difference (MID) were evaluated for the CushingQOL questionnaire using data from patients diagnosed with CD who participated in the phase III clinical trial designed to assess the safety and efficacy of different doses of pasireotide. METHODS: Adult patients (n = 162) with CD participated in a randomized, double-blind, multinational, phase III clinical trial. Patients received subcutaneous pasireotide (600 µg or 900 µg) twice daily for 3 months (double blind). After 3 months, some patients were unblinded based on their mean urinary free cortisol (mUFC) levels and were given the chance to increase their dosage, while the other patients remained blinded. At month 6, an open-label 6-month period began. The CushingQOL questionnaire was self-administered four times (baseline [n = 160], and at months 3 [n = 134], 6 [n = 113], and 12 [n = 76]). A confirmatory factor analysis (CFA) was conducted. Reliability estimates were calculated for internal consistency (coefficient alpha) and test retest (intraclass correlation coefficients [ICCs]) for patients with stable hypercortisolism at month 3 and month 6. Construct validity hypotheses (correlations), mean differences in known groups (ANOVAs), and responsiveness effect sizes (Guyatt's) were estimated based on measures of cortisol, body mass index (BMI), waist circumference, weight, facial rubor (redness), striae (stretch marks), bruising, supraclavicular fat pad, dorsal fat pad, and results of the Beck Depression Inventory II (BDI-II). The half-standard deviation distribution method was used to estimate MID. RESULTS: CFA loadings supported a one-factor solution for the CushingQOL questionnaire items. Internal consistency reliability (0.87-0.88) and ICCs (0.87) were high. Construct validity hypotheses were in the anticipated direction. Changes in CushingQOL scores were moderately correlated with changes in mUFC levels, in BMI, and in weight. Mean scores for minimally depressed patients were significantly higher (indicating better HR-QOL) than for severely depressed patients. Moderate Guyatt's responsiveness effect sizes were observed for patients who achieved reductions in weight, BMI, and waist circumference. Using the half-standard deviation method, an estimate of the MID was computed as 10.1. CONCLUSIONS: This study provided evidence within the context of a longitudinal design that the CushingQOL questionnaire is a reliable, valid, and responsive instrument for the assessment of HR-QOL in adults with CD in accordance with recommendations set forth by regulatory agencies in the USA and Europe.

RESUMO

The neuropeptide Y (NPY) system is a multireceptor/multiligand system consisting of four receptors in humans (hY(1), hY(2), hY(4), hY(5)) and three agonists (NPY, PYY, PP) that activate these receptors with different potency. The relevance of this system in diseases like obesity or cancer, and the different role that each receptor plays influencing different biological processes makes this system suitable for the design of subtype selectivity studies. In this review we focus on the latest findings within the NPY system, we summarize recent mutagenesis studies, structure activity relationship studies, receptor chimera, and selective ligands focusing also on the binding mode of the native agonists.

RESUMO

OBJECTIVE: To evaluate health-related quality of life (HRQoL) in Cushing's syndrome (CS) with the disease-generated CushingQoL questionnaire and to confirm its psychometric properties of test-retest reliability and sensitivity to change. DESIGN: Clinical practice conditions in a tertiary referral center. METHODS: The CushingQoL and EuroQoL questionnaires were administered at baseline and during follow-up and correlated with clinical parameters in 59 patients with CS. To check test-retest reliability, stable patients (either biochemically cured or with active hypercortisolism) were evaluated twice. To investigate sensitivity to change, new patients were evaluated at diagnosis and twice more following improvement after successful surgery. RESULTS: At baseline, patients with active disease scored lower (indicating worse HRQoL) than those cured on the CushingQoL (46 ± 14 vs 58 ± 20, P<0.05) but not on the EuroQoL-visual analog scale (VAS; 64 ± 20 vs 70 ± 16, P NS). Test-retest reliability of CushingQoL was confirmed in stable patients, both in the 'cured group' (intraclass correlation coefficient (ICC)=0.78, n=34) and in the 'active group' (ICC=0.66, n=14). Sensitivity to change was confirmed in the 'improvement group' (n=11), as the CushingQoL score increased 4 ± 1.5 and 9 ± 3 months after surgery (P<0.01 and <0.001 respectively); the EuroQoL-VAS only improved after 9 ± 3 months (P<0.01). Effect sizes were 1.02 and 1.86 for CushingQoL at 4 ± 1.5 and 9 ± 3 months respectively. Finally, scores of both questionnaires were correlated (r=0.504; P<0.001). CONCLUSIONS: The CushingQoL questionnaire shows good test-retest reliability and sensitivity to change in clinical practice conditions.

RESUMO

OBJECTIVES: Develop and validate a Spanish society of contraception quality-of-life (SEC-QOL) questionnaire to assess the impact of contraceptive methods on the health-related quality of life (HRQOL) of women. METHODS: SEC-QOL was developed following a standardized procedure including review of the literature, interviews with contraception users, and the administration of a pilot questionnaire to 187 women. SEC-QOL consists of 19 items and includes five dimensions. To validate the questionnaire, a multicenter, observational, prospective study was conducted in Spain. The following three study groups were defined: group A (n = 129) comprised women using effective contraceptive methods; group B (n = 251), comprised women about to start using an effective method; and group C (n = 73) comprised women using no or poorly effective contraception. All women attended baseline and final visits (4 ± 1 months). Participants completed the SEC-QOL, psychological well-being index, EuroQol five-dimensional questionnaire, and perceived health state questionnaires. RESULTS: At baseline, women from group A had a better HRQOL in all SEC-QOL dimensions, except for breast symptoms. Heavier menstrual bleeding, more androgenic and breast symptoms, menstrual pain, and not using hormonal contraceptive methods were associated with lower HRQOL. SEC-QOL scores showed moderate correlations to psychological well-being index and slightly lower correlation to EuroQol five-dimensional questionnaire scores. At follow-up, HRQOL had improved in all groups; most markedly in group B, which obtained an average effect size of 0.59. The minimum important difference was established as a 3.4-point change in the global SEC-QOL score. SEC-QOL obtained a Cronbach's α of 0.88 and an intraclass correlation coefficient of 0.82. CONCLUSIONS: SEC-QOL is a valid, reliable, and sensitive to change questionnaire for use in daily clinical practice and future research projects on contraception.

RESUMO

The aim of this validation study was to assess the measurement properties of the CECA (Spanish acronym for the Specific Questionnaire for Condylomata Acuminata) in patients with anogenital condylomas. A total of 247 patients aged > 18 years completed the questionnaire on 2 occasions as well as the Dermatology Life Quality Index (DLQI). The CECA questionnaire showed good internal consistency (Cronbach's alpha values of 0.86 and 0.91 in the emotional and sexual activity dimensions) and good testretest reliability (intraclass correlation coefficient 0.76 emotional dimension, 0.82 sexual activity dimension). Patients with de novo lesions and those with more extensive lesions and larger number of warts showed poorer health-related quality of life. CECA and DLQI scores correlated moderately. Patients whose lesions cleared at follow-up or with a reduction of >or= 50% showed a better improvement of health-related quality of life. The CECA questionnaire is a valid, reliable and sensitive tool for the assessment of health-related quality of life in patients with anogenital warts.

RESUMO

INTRODUCTION: Skeletal-related events (SREs) from malignant bone disease cause considerable morbidity and can dramatically reduce patients' quality of life. DISCUSSION: Pathologic fractures often require surgical intervention and palliative radiotherapy. Thus, patients suffer impaired mobility, loss of functional independence, and diminished health-related quality of life (HRQOL). Bisphosphonates can delay the onset and reduce the incidence of SREs and have become the standard of care for the treatment of malignant bone disease; however, minimal information on the effects of bisphosphonate treatment on HRQOL is available. Targeted HRQOL assessments for patients with malignant bone disease are currently under development and are discussed herein.

RESUMO

OBJECTIVE: This study aimed to assess the prevalence of nocturia and its impact on quality of life (QoL) in Spanish patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH). RESEARCH DESIGN AND METHODS: This was a Spanish, multicentre, cross-sectional study. Outpatients aged 60 years and over with LUTS/BPH, a prostate size > or = 25 g, untreated for LUTS/BPH and responding to the International Prostate Symptom Score (I-PSS) were included. Nocturia was defined as > or = 2 nocturnal voids/night. The Spanish version of the Nocturia-specific Quality of Life (N-QoL) questionnaire assessed the impact of nocturia on QoL, with a low score indicating a poor QoL due to nocturia. RESULTS: A total of 502 patients were included; mean age 68.1 +/- 5.7 years, mean I-PSS 14.9 +/- 7.1, mean prostate size 50.9 +/- 20 g. The overall prevalence of nocturia was 83.1% (95% confidence interval [CI]: 79.8-86.4). Patients with nocturia had a lower score on the overall N-QoL questionnaire and the sleep/energy and bother/concern domains than those without nocturia (p < 0.001); 42.9% of patients with nocturia stated that they had a good-very good QoL compared to 90.6% in those without nocturia (p < 0.001). CONCLUSION: This study shows a high prevalence of nocturia in Spanish LUTS/BPH patients. Nocturia negatively impacts on the QoL of LUTS/BPH patients, which is reflected in worse sleep, reduced energy levels and increased bother and concern. Therefore adequate treatment of this symptom is necessary.

RESUMO

Cancer is a high incidence disease, forcing healthcare systems to assign a significant amount of resources to its treatment. New developments have arisen recently: development of new agents that act at specific steps of cellular differentiation and proliferation and identification of predictive genetic markers which allow sub-groups of patients that will benefit from these agents, alone or in combination with chemotherapy, to be targeted. The majority of new drugs coming to the market combine greater clinical benefit and higher costs. Constraints on healthcare budgets worldwide make it necessary to rationalise the expense by prioritising allocation of available resources to the most efficient interventions, so that the best possible clinical result can be obtained at a reasonable cost and with the best quality of life for the patient. Economic evaluation studies represent the only tool available to scientifically determine the cost-effectiveness of new treatments and the budgetary impact of their introduction to the therapeutic arsenal available for the treatment of cancer.

RESUMO

OBJECTIVE: To determine whether impaired quality of life (QoL) in adults with GH deficiency (GHD) is reversible with long-term GH therapy and whether the responses in QoL dimensions differ from each other. METHODS: QoL was measured by the Quality of Life-Assessment for Growth Hormone Deficiency in Adults (QoL-AGHDA) in general population samples in England & Wales, The Netherlands, Spain and Sweden (n = 892, 1038, 868 and 1682 respectively) and compared with corresponding patients' data from KIMS (Pfizer International Metabolic Database) (n = 758, 247, 197 and 484 respectively) for 4-6 years a follow-up. The subsets of patients from England and Wales, and Sweden with longitudinal data for 5 years' follow-up were also analysed. The change of the total QoL-AGHDA scores and responses within dimensions were evaluated. Subanalyses were performed to identify any specificity in response pattern for gender, age, disease-onset and aetiology. RESULTS: Irrespective of the degree of impairment, overall QoL improved dramatically in the first 12 months, with steady progress thereafter towards the country-specific population mean. Problems with memory and tiredness were the most serious burden for untreated patients, followed by tenseness, self-confidence and problems with socialising. With treatment, these improved in the reverse order, normalising for the latter three. CONCLUSIONS: Long-term GH replacement results in sustained improvements towards the normative country-specific values in overall QoL and in most impaired dimensions. The lasting improvement and almost identical pattern of response in each patient subgroup and independent of the level of QoL impairment support the hypothesis that GHD may cause these patients' psychological problems.

RESUMO

The study aims to assess the effectiveness of an educational leaflet in the prevention of external genital warts recurrences after achieving clearance with topical immune response modifiers treatment. A six-month follow-up, prospective, open, multi-centre randomized by centres study was conducted, which included a total of 216 patients. A total of 103 (47.7%) patients were given an educational leaflet. In all, 201 subjects (93.1%) came to the second follow-up visit, of which 62.7% achieved condyloma acuminatum (CA) clearance. During follow-up, 15% (confidence intervals [CI] 95%, 7.1-26.6%) of the patients who were given the educational leaflet, and 33.3% (CI 95%, 20.4-48.4%) of those who were not given the educational leaflet showed CA recurrences; the global rate of CA recurrence at the end of the six-month follow-up was 23.1% (CI 95%, 15.6-32.2%). The educational leaflet has therefore proved to be effective at reducing the recurrence rate after successful treatment with immune response modifiers.
