RESUMEN

PURPOSE: We sought to evaluate the prognostic impact of prostate-specific antigen (PSA) at 6 months after completion of radiotherapy (RT) in patients treated with RT alone, RT plus short-term (st; 3-6 months), and RT plus long-term (lt; 24-36 months) androgen-deprivation therapy (ADT). PATIENTS AND METHODS: Individual patient data were obtained from 16 randomized trials evaluating RT ± ADT for localized prostate cancer (PCa) between 1987 and 2011. The lowest PSA recorded within 6 months after RT completion was identified and categorized as < or ≥0.1 ng/mL. The primary outcomes were metastasis-free survival (MFS), PCa-specific mortality (PCSM), and overall survival (OS), from 12 months after random assignment. RESULTS: Ninety-eight percent (n = 2,339/2,376) of patients allocated to RT alone, 84% (n = 4,756/5,658) allocated to RT + stADT, and 77% (n = 1,258/1,626) allocated to RT + ltADT had PSA ≥0.1 ng/mL within 6 months after completing RT. PSA ≥0.1 ng/mL was associated with lower MFS and OS and higher PCSM among patients allocated to RT ± ADT (RT - MFS: hazard ratio [HR], 2.24 [95% CI, 1.21 to 4.16]; PCSM: subdistribution hazard ratio [sHR], 1.82 [0.51 to 6.49]; OS: HR, 1.72 [0.97 to 3.05]; RT + stADT - MFS: HR, 1.27 [1.12 to 1.44]; PCSM: sHR, 2.10 [1.52 to 2.92]; OS: HR, 1.26 [1.11 to 1.44]; RT + ltADT - MFS: HR, 1.58 [1.27 to 1.96]; PCSM: sHR, 1.97 [1.11 to 3.49]; OS: HR, 1.59 [1.27 to 1.99]). Five-year MFS rates among patients allocated to RT, RT + stADT, and RT + ltADT were 91% versus 79%, 83% versus 76%, and 87% versus 74%, respectively, based on PSA < or ≥0.1 ng/mL. CONCLUSION: PSA ≥0.1 ng/mL within 6 months after RT completion was prognostic for lt outcomes in patients treated with RT ± ADT for localized PCa. This can be used to counsel patients treated with RT ± ADT and in guiding clinical trial design evaluating novel systemic therapies with RT + ADT as well as (de)intensification strategies.

RESUMEN

BACKGROUND: Acute kidney injury (AKI) is a common complication of hospitalisations. This national audit assessed the care received by patients with AKI in hospital Trusts in England and Wales. METHODS: Twenty four hospital Trusts across England and Wales took part. Patients with AKI stage2/3 were identified using the UK Renal Registry AKI master patient index. Data was returned through a secure portal with linkage to hospital episode statistic mortality and hospitalisation data. Completion rates of AKI care standards and regional variations in care were established. RESULTS: 989 AKI episodes were included in the analyses. In-hospital 30-day mortality was 31-33.1% (AKI 2/3). Standard AKI interventions were completed in >80% of episodes. Significant inter-hospital variation remained in attainment of AKI care standards after adjustment for age and sex. Recording of urinalysis (41.9%) and timely imaging (37.2%) were low. Information on discharge summaries relating to medication changes/re-commencement and follow-up blood tests associated with reduced mortality. No quality indicators relating to clinical management associated with mortality. Better communication on discharge summaries associated with reduced mortality. CONCLUSIONS: Outcomes for patients with AKI in hospital remain poor. Regional variation in care exists. Work is needed to assess whether improving and standardising care improves patient outcomes.

RESUMEN

OBJECTIVE: Coronavirus disease 2019 (COVID-19) has evolved into a global pandemic, affecting a wide range of medical and surgical specialties. During COVID-19, we assisted in the reallocation of medical resources and services, as well as social distancing measures, and many patients with chronic diseases and comorbidities may have experienced difficulties in obtaining the correct medical care. The aim of the study was to investigate the impact of the COVID-19 pandemic on major adverse cardiovascular events (MACE) and major adverse limb events (MALE) in patients with peripheral arterial disease (PAD) and chronic limb-threatening ischemia (CLTI), compared to previous years. PATIENTS AND METHODS: We evaluated 1,335 hospital admissions of 877 patients with PAD admitted to Policlinico A. Gemelli Hospital between January 2017 and February 2020 and 368 hospital admissions of 272 patients with PAD admitted to the Policlinico A. Gemelli Hospital between March 2020 and March 2021. Data on demographic characteristics, comorbidities, symptoms, physical and radiological findings, laboratory tests, and routine visits before or after discharge were collected from electronic medical records. RESULTS: Emergency room (ER) admissions among PAD patients during COVID-19 were higher than before the pandemic [190 (51.63%) vs. 579 (43.37%), p = 0.01]. A MACE was found in 78 (5.84%) pre-pandemic hospitalizations and 126 (34.24%) pandemic hospitalizations (p < 0.01). A MALE was identified in 942 (70.56%) pre-pandemic hospitalizations and 331 (89.95%) pandemic hospitalizations (p < 0.01). Amputation rates during the pandemic were higher than before the pandemic [80 (21.74%) vs. 191 (14.31%), p < 0.01]. The number of in-hospital deaths did not differ between the pandemic and pre-pandemic periods [11 (2.99%) vs. 51 (3.82%), p = 0.55]. CONCLUSIONS: In patients with PAD and CLTI, the number of MACE, MALE, and amputations was higher during the COVID-19 period compared to the three years before the pandemic.

RESUMEN

Finding effective ways to perform cancer sub-typing is currently a trending research topic for therapy opti-mization and personalized medicine. Stemming from genomic field, several algorithms have been proposed. In the context of texture analysis, limited efforts have been attempted, yet imaging information is known to entail useful knowledge for clinical practice. We propose a distant supervision model for imaging-based cancer sub-typing in Intrahepatic Cholangiocar-cinoma patients. A clinically informed stratification of patients is built and homogeneous groups of patients are characterized in terms of survival probabilities, qualitative cancer variables and radiomic feature description. Moreover, the contributions of the information derived from the ICC area and from the peri tumoral area are evaluated. The findings suggest the reliability of the proposed model in the context of cancer research and testify the importance of accounting for data coming from both the tumour and the tumour-tissue interface. Clinical relevance - In order to accurately predict cancer prognosis for patients affected by ICC, radiomic variables of both core cancer and surrounding area should be exploited and employed in a model able to manage complex information.

RESUMEN

BACKGROUND: To investigate the impact of COVID-19 outbreak on the diagnosis and treatment of non-muscle invasive bladder cancer (NMIBC). METHODS: A retrospective analysis was performed using an Italian multi-institutional database of TURBT patients with high-risk urothelial NMIBC between January 2019 and February 2021, followed by Re-TURBT and/or adjuvant intravesical BCG. RESULTS: A total of 2591 patients from 27 institutions with primary TURBT were included. Of these, 1534 (59.2%) and 1056 (40.8%) underwent TURBT before and during the COVID-19 outbreak, respectively. Time between diagnosis and TURBT was significantly longer during the COVID-19 period (65 vs. 52 days, p = 0.002). One thousand and sixty-six patients (41.1%) received Re-TURBT, 604 (56.7%) during the pre-COVID-19. The median time to secondary resection was significantly longer during the COVID-19 period (55 vs. 48 days, p < 0.0001). A total of 977 patients underwent adjuvant intravesical therapy after primary or secondary resection, with a similar distribution across the two groups (n = 453, 86% vs. n = 388, 86.2%). However, the proportion of the patients who underwent maintenance significantly differed (79.5% vs. 60.4%, p < 0.0001). CONCLUSIONS: The COVID-19 pandemic represented an unprecedented challenge to our health system. Our study did not show significant differences in TURBT quality. However, a delay in treatment schedule and disease management was observed. Investigation of the oncological impacts of those differences should be advocated.

RESUMEN

BACKGROUND: We investigated the effectiveness and safety of mirabegron oral treatment in a group of patients with Parkinson's disease (PD) and overactive bladder (OAB), refractory to antimuscarinics. MATERIALS AND METHODS: Thirty patients with PD and refractory OAB were prospectively included in the study. At baseline, motor symptoms, severity of disease and cognitive status were assessed with the Hoehn-Yahr Scale, the Unified Parkinson's disease Rating Scale, the Mini Mental State examination and the Montreal Cognitive Assessment. At baseline, urinary symptoms, satisfaction with treatment and the impact of urinary incontinence on quality of life (QoL) were assessed with the 3-day voiding diary, the Visual Analogue Scale (VAS), the Incontinence-QoL questionnaire and urodynamics. Patients started assuming mirabegron 50 mg tablets once daily. Evaluation of urinary symptoms and related questionnaires, motor symptoms, severity of PD and uroflowmetry with postvoid residual volume measurement were then repeated at the 3- and 6-month follow up. Side effects were also noted. RESULTS: At baseline, the most frequently reported urinary symptoms were: urinary urgency (present in all the patients), urge urinary incontinence in 28/30 (93.3%) and increased daytime urinary frequency in 25 (83.3%) patients. At the 3-month follow up, 7 out of the 30 patients achieved a complete urinary continence. Significant improvements in VAS and Incontinence-QoL scores were observed in 24 patients. These benefits were maintained for the whole observation period. Four patients discontinued treatment due to poor efficacy, and two due to the cost of the drug. CONCLUSIONS: Mirabegron is a safe and effective treatment in patients with PD and OAB refractory to anticholinergics in the short-term follow up.

RESUMEN

Purpose: Non-muscle-invasive bladder cancer (NMIBC) is a malignant disease characterized by high heterogeneity, which corresponds to dysregulated gene expression and alternative splicing (AS) profiles. Bioinformatics analyses of splicing factors potentially linked to bladder cancer progression identified the heterogeneous nuclear ribonucleoprotein I (i.e., PTBP1) as candidate. This study aimed at investigating whether PTBP1 expression associates with clinical outcome in patients with NMIBC.Experimental Design: A cohort of 152 patients presenting with primary NMIBC (pTa-pT1) was enrolled. Primary NMIBCs were assessed for PTBP1 expression by IHC, and the results were correlated with clinical data using Kaplan-Meier curves and Cox regression analyses. Cell proliferation and survival assays were performed to assess the function of PTBP1. Furthermore, the impact of PTBP1 on the AS pattern of specific bladder cancer-related genes was investigated in cancer cell lines and in patients' specimens.Results: Public datasets querying highlighted a positive correlation between PTBP1 expression and NMIBC progression, which was then confirmed by IHC analysis. High PTBP1 expression was associated with worse clinical outcome in terms of incidence of tumor relapse and survival in patients with NMIBC. Interestingly, downregulation of PTBP1 in bladder cancer cell lines affected prosurvival features. Accordingly, PTBP1 modulated AS of bladder cancer-related genes in cell lines and patient's specimens.Conclusions: PTBP1 expression correlates with disease progression, poor prognosis, and worse survival in patients with NMIBC. Downregulation of PTBP1 expression affects prosurvival features of bladder cancer cells and modulates AS of genes with relevance for bladder cancer, suggesting its role as an outcome-predictor in this disease.

RESUMEN

INTRODUCTION: The aim of this multicenter study was to investigate the prognostic impact of residual T1 high-grade (HG)/G3 tumors at re-transurethral resection (TUR of bladder tumor) in a large multi-institutional cohort of patients with primary T1 HG/G3 bladder cancer (BC). PATIENTS AND METHODS: The study period was from January 2002 to -December 2012. A total of 1,046 patients with primary T1 HG/G3 and who had non-muscle invasive BC (NMIBC) on re-TUR followed by adjuvant intravesical Bacillus Calmette-Guerin (BCG) therapy with maintenance were included. Endpoints were time to disease recurrence, progression, and overall and cancer-specific death. RESULTS: A total of 257 (24.6%) patients had residual T1 HG/G3 tumors. The presence of concomitant carcinoma in situ, multiple and large tumors (> 3 cm) at first TUR were associated with residual T1 HG/G3. Five-year recurrence-free survival (RFS), progression-free survival (PFS), overall survival (OS), and cancer-specific survival (CSS) were 17% (CI 11.8-23); 58.2% (CI 50.7-65); 73.7% (CI 66.3-79.7); and 84.5% (CI 77.8-89.3), respectively, in patients with residual T1 HG/G3, compared to 36.7% (CI 32.8-40.6); 71.4% (CI 67.3-75.2); 89.8% (CI 86.6-92.3); and 95.7% (CI 93.4-97.3), respectively, in patients with NMIBC other than T1 HG/G3 or T0 tumors. Residual T1 HG/G3 was independently associated with RFS, PFS, OS, and CSS in multivariable analyses. CONCLUSIONS: Residual T1 HG/G3 tumor at re-TUR confers worse prognosis in patients with primary T1 HG/G3 treated with maintenance BCG. Patients with residual T1 HG/G3 for primary T1 HG/G3 are very likely to fail BCG therapy alone.

RESUMEN

BACKGROUND: Serum levels of neutrophils, platelets, and lymphocytes have been recognized as factors related to poor prognosis for many solid tumors, including bladder cancer (BC). OBJECTIVE: To evaluate the prognostic role of the combination of the neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and lymphocyte/monocyte ratio (LMR) in patients with high-risk non-muscle-invasive urothelial BC (NIMBC). DESIGN, SETTING, AND PARTICIPANTS: A total of 1151 NMIBC patients who underwent first transurethral resection of the bladder tumor (TURBT) at 13 academic institutions between January 1, 2002 and December 31, 2012 were included in this analysis. The median follow-up was 48 mo. INTERVENTION: TURBT with intravesical chemotherapy or immunotherapy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Multivariable Cox regression analysis was performed to identify factors predictive of recurrence, progression, cancer-specific mortality, and overall mortality. A systemic inflammatory marker (SIM) score was calculated based on cutoffs for NLR, PLR, and LMR. RESULTS AND LIMITATIONS: The 48-mo recurrence-free survival was 80.8%, 47.35%, 20.67%, and 17.06% for patients with an SIM score of 0, 1, 2, and 3, respectively (p<0.01, log-rank test) while the corresponding 48-mo progression free-survival was 92.0%, 75.67%, 72.85%, and 63.1% (p<0.01, log-rank test). SIM scores of 1, 2, and 3 were associated with recurrence (hazard ratio [HR] 3.73, 7.06, and 7.88) and progression (HR 3.15, 4.41, and 5.83). Limitations include the lack of external validation and comparison to other clinical risk models. CONCLUSIONS: Patients with high-grade T1 stage NMIBC with high SIM scores have worse oncologic outcomes in terms of recurrence and progression. Further studies should be conducted to stratify patients according to SIM scores to identify individuals who might benefit from early cystectomy. PATIENT SUMMARY: In this study, we defined a risk score (the SIM score) based on the measurement of routine systemic inflammatory markers. This score can identify patients with high-grade bladder cancer not invading the muscular layer who are more likely to suffer from tumor recurrence and progression. Therefore, the score could be used to select patients who might benefit from early bladder removal.

RESUMEN

Bladder cancer is very common and most cases are diagnosed as nonmuscle invasive disease, which is characterized by its propensity to recur and progress. Intravesical therapy is used to delay recurrence and progression, while cystectomy is reserved for patients who are refractory to transurethral resection and intravesical therapy. There is an increasing interest in methods to enhance the delivery of intravesical chemotherapeutic agents to improve efficacy. In vitro and in vivo studies demonstrated that electro-osmosis of mitomycin C (MMC) is more effective in delivering this drug into the urothelium, lamina propria, and superficial muscle layers of the bladder wall than is passive transport. Higher MMC tissue concentrations might have a clinical impact in the treatment of nonmuscle invasive bladder cancer (NMIBC). In randomized trials, intravesical electro-osmotic MMC was associated with superior response rate in high-risk NMIBC cancer, compared with passive diffusion MMC transport. New strategies such as intravesical Bacillus Calmette-Guerin (BCG) combined with electro-osmotic MMC as well as intravesical pre-operative electro-osmotic MMC provided promising results in terms of higher remission rates and longer remission times.Device-assisted intravesical chemotherapy may be a useful ancillary procedure in the treatment of NMIBC. Its evaluation must be planned with respect to the technical functioning of equipment and their use for a clear purpose to avoid the financial and human costs associated with incorrect therapies.

RESUMEN

Clinical trials have shown that hexaminolevulinate (HAL) fluorescence cystoscopy improves the detection of bladder tumors compared with standard white-light cystoscopy, resulting in more efficacious treatment. However, some recent meta-analyses report controversially on recurrence-free rates with this procedure. A systematic review of literature was performed from December 2014 to January 2015 using the PubMed, Embase and Cochrane databases for controlled trials on photodynamic diagnosis (PDD) with HAL. A total of 154 publications were found up to January 2015. Three of the authors separately reviewed the records to evaluate eligibility and methodological quality of clinical trials. A total of 16 publications were considered eligible for analysis. HAL-PDD-guided cystoscopy increased overall tumor detection rate (proportion difference 19%, 95% confidence interval [CI] 0.152-0.236) although the benefit was particularly significant in patients with carcinoma in situ (CIS) lesion (proportion difference 15.7%, 95% CI 0.069-0.245) and was reduced in papillary lesions (Ta proportion difference 5.9%, 95% CI 0.014-0.103 and T1 proportion difference 1.2%, 95% CI 0.033-0.057). Moreover, there were 15% of patients (95% CI 0.098-0.211) with at least one additional tumor seen with PDD. With regard to recurrence rates, the data sample was insufficient for a statistical analysis, although the evaluation of raw data showed a trend in favor of HAL-PDD. This meta-analysis confirms the increased tumor detection rate by HAL-PDD with a most pronounced benefit for CIS lesion.

RESUMEN

Dental composite resins are biomaterials commonly used to aesthetically restore the structure and function of teeth impaired by caries, erosion, or fracture. Residual monomers released from resin restorations as a result of incomplete polymerization processes interact with living oral tissues. The objective of this study was to evaluate the genotoxicity of a common dental composite material (Enamel Plus-HFO), in subjects with average 13 filled teeth with the same material, compared to a control group (subjects having neither amalgam nor composite resin fillings). Genotoxicity assessment of composite materials was carried out in vitro in human peripheral blood leukocytes using sister-chromatid exchange (SCE) and chromosomal aberrations (CA) cytogenetic tests. The results of correlation and multiple regression analyses confirmed the absence of a relationship between SCE/cell, high frequency of SCE(HFC) or CA frequencies and exposure to dental composite materials. These results indicate that composite resins used for dental restorations differ extensively in vivo in their cytotoxic and genotoxic potential and in their ability to affect chromosomal integrity, cell-cycle progression, DNA replication and repair.

RESUMEN

OBJECTIVE: To evaluate the concordance and prognostic role of histologic variants of bladder urothelial carcinoma in transurethral resection of bladder tumor (TURBT) and radical cystectomy (RC) specimens. METHODS: Clinicopathologic information available at the time of RC and follow-up data from 4110 RC specimens, collected between January 2000 and December 2009 at 17 tertiary referral centers were retrospectively analyzed and evaluated for the presence or absence of uncommon variants of bladder urothelial carcinoma. The presence or absence of uncommon variants of bladder urothelial carcinoma was evaluated on previous TURBT specimens of patients undergoing RC. Cox regression was used to assess the impact of these parameters on cancer-specific survival, and the Kaplan-Meier test for disease-free survival was plotted for survival estimate. RESULTS: Of 4110 patients, 579 were found to have uncommon variants of bladder urothelial carcinoma at RC (14.1%), whereas 266 (6.4%) at TURBT. A lack of agreement about uncommon variants was observed between TURBT and RC specimens in the entire population (P <.001). The presence of uncommon variants at TURBT was associated with an increased risk of pathologic upstage (hazard ratio, 3.24; confidence interval, 1.19-6.37; P <.003) and significant decrease in cancer-specific survival and recurrence-free survival (P <.001). CONCLUSION: Although the concordance of presence of uncommon histologic variants of urothelial bladder carcinoma between TURBT and RC is low, the presence of uncommon histologic variants of urothelial bladder carcinoma at TURBT is associated with a less favorable clinical outcome.

RESUMEN

INTRODUCTION: Differences in facial preferences between heterosexual men and women are well documented. It is still a matter of debate, however, how variations in sexual identity/sexual orientation may modify the facial preferences. AIM: This study aims to investigate the facial preferences of male-to-female (MtF) individuals with gender dysphoria (GD) and the influence of short-term/long-term relationships on facial preference, in comparison with healthy subjects. METHODS: Eighteen untreated MtF subjects, 30 heterosexual males, 64 heterosexual females, and 42 homosexual males from university students/staff, at gay events, and in Gender Clinics were shown a composite male or female face. The sexual dimorphism of these pictures was stressed or reduced in a continuous fashion through an open-source morphing program with a sequence of 21 pictures of the same face warped from a feminized to a masculinized shape. MAIN OUTCOME MEASURES: An open-source morphing program (gtkmorph) based on the X-Morph algorithm. RESULTS: MtF GD subjects and heterosexual females showed the same pattern of preferences: a clear preference for less dimorphic (more feminized) faces for both short- and long-term relationships. Conversely, both heterosexual and homosexual men selected significantly much more dimorphic faces, showing a preference for hyperfeminized and hypermasculinized faces, respectively. CONCLUSIONS: These data show that the facial preferences of MtF GD individuals mirror those of the sex congruent with their gender identity. Conversely, heterosexual males trace the facial preferences of homosexual men, indicating that changes in sexual orientation do not substantially affect preference for the most attractive faces.

RESUMEN

Alternative splicing (AS) is tightly coupled to transcription for the majority of human genes. However, how these two processes are linked is not well understood. Here, we unveil a direct role for the transcription factor FBI-1 in the regulation of AS. FBI-1 interacts with the splicing factor SAM68 and reduces its binding to BCL-X mRNA. This, in turn, results in the selection of the proximal 5' splice site in BCL-X exon 2, thereby favoring the anti-apoptotic BCL-XL variant and counteracting SAM68-mediated apoptosis. Conversely, depletion of FBI-1, or expression of a SAM68 mutant lacking the FBI-1 binding region, restores the ability of SAM68 to induce BCL-XS splicing and apoptosis. FBI-1's role in splicing requires the activity of histone deacetylases, whose pharmacological inhibition recapitulates the effects of FBI-1 knockdown. Our study reveals an unexpected function for FBI-1 in splicing modulation with a direct impact on cell survival.

RESUMEN

OBJECTIVE: To evaluate the efficacy and safety of duloxetine hydrochloride in the treatment of patients affected by chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). METHODS: Thirty-eight CP/CPPS patients completed the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) and International Index of Erectile Function-Erectile Function-5 (IIEF-5) questionnaires, uroflowmetry, and evaluation of psychologic status using Hamilton Anxiety Scale (HAM-A) and Hamilton Depression Scale (HAM-D). Patients were randomly assigned to 2 treatments groups. Treatment in group 1 consisted of a simultaneous oral administration of tamsulosin (0.4 mg/d, 60 mg/d), saw palmetto (320 mg/d), and duloxetine (60 mg/d). Treatment in group 2 consisted of tamsulosin (0.4 mg/d) and saw palmetto (320 mg/d). NIH-CPSI and IIEF-5 questionnaires, uroflowmetry, and evaluation of the psychological status were repeated at 16 weeks of follow-up. RESULTS: At 16 weeks, a significant improvement in NIH-CPSI pain subscore, NIH-CPSI quality of life subscore, and NIH-CPSI total score were observed in group 1 patients compared with those in group 2 (P <.01, respectively), together with a significant improvement in HAM-A and HAM-D scores (P <.01, respectively). Patients in group 2 showed a significant improvement in NIH-CPSI total score, in the urinary symptoms subscore, and in the HAM-A total score. No significant differences were observed in IIEF-5 scores in the 2 groups. Maximum flow rate significantly increased in both groups. In group 1, 20% of patients stopped the study due to adverse effects. CONCLUSION: The use of duloxetine in a multimodal treatment with an α-blocker medication and a saw palmetto extract allowed better results in controlling clinical symptoms, psychologic status and quality of life patients affected by CP/CPPS.

RESUMEN

In the management of non-muscle invasive bladder cancer (NMIBC), high-level evidence supports the widespread practice of intravesical therapy with mitomycin-C (MMC). Randomized trials showed a significant reduction in short-term recurrence compared with transurethral resection of bladder tumor (TURBT) alone, but little effect on long-term and no impact at all in preventing progression. Electromotive drug administration (EMDA®) offers a means of controlling and enhancing the tissue transport of certain drugs, in order to increase their efficacy. In both laboratory and clinical studies, intravesical electromotive drug administration (EMDA) increases MMC bladder uptake, resulting in an improved clinical efficacy in NMIBC without systemic side effects. New frameworks for treatment of NMIBC - e.g., sequential intravesical BCG and EMDA/MMC, as well as intravesical EMDA/MMC immediately before TURBT - have provided promising preliminary results with higher remission rates and longer remission times, and they are a priority to minimise the costs of disease management. These findings suggest EMDA-enhanced MMC efficacy against urothelial cancer could be a major therapeutic breakthrough in the treatment of NMIBC.

RESUMEN

Dyslipidemia represents a common metabolic alteration in chronic kidney disease (CKD). Alterations can be different depending on the stage of the disease and the extent of proteinuria. Despite the high cardiovascular risk in patients with renal impairment, only a small percentage of patients receive adequate cholesterol-lowering therapy. The use of statins, inhibitors of the endogenous synthesis of cholesterol in patients with CKD, represents an efficient therapeutic instrument for reducing cardiovascular risk, at least in the early stage of the disease. Such evidence is currently lacking in dialysis, that is a setting where cardiovascular mortality is not consistently due to classical atherosclerosis. In addition to their efficacy, statins are proved as safe drugs with a high tolerability profile in CKD. In the case of intolerant patients, a new therapeutic perspective is represented by ezetimibe, inhibitor of intestinal absorption of cholesterol, whose effectiveness and tolerability allow its use throughout all stages of the renal disease.

RESUMEN

Patients with chronic migraine (CM) and medication overuse (MO) have high frequency of psychiatric comorbidity. Aims of this open label, prospective, independent study were: to evaluate the efficacy of duloxetine in a sample of patients with MO due to CM and with concomitant depression; to investigate, if the presence of OCD influences the outcome in this subgroup of patients. A total of 50 consecutive patients (40 F,10 M, aged 20-65 years, mean 39.4 years) from those attending our Headache Center to undergo an inpatient withdrawal programme followed by anti-migraine prophylaxis was enrolled. After a 1-month baseline period, all patients were prescribed duloxetine 30 mg in the morning for the first week, and 60 mg for the following 12 weeks. They filled a daily headache diary during the whole study period. They also completed Hamilton depression rating scale (HDRS) and migraine disability assessment scale (MIDAS) at baseline and at the 12-week follow-up. The primary outcome measure was the percentage of responders, i.e. of patients with a reduction ≥50 % in headache frequency as well as in symptomatic drug consumption. Comparison between patients with and without OCD was performed. Our results showed a rather high responder rate in the total sample (64 %), while none of the patients with OCD fell among responders. MIDAS and HDRS scores had a more evident decrease in patients without OSD. These findings suggest that duloxetine may be effective in patients with MO due to CM and with comorbid depression. They also confirm the importance of a systematic assessment of the psychopathological profile in these patients, and indicate that clinicians should be aware of the relevant prognostic role of OCD in favoring a poor outcome and persistent disability in headache patients with MO.
