Knowledge and Attitudes of Health Care Professionals and Laypeople in Relation to Brain Death Diagnosis and Organ Donation in Hungary: A Questionnaire Study

ObjectivesThe aim of the present work was to assess the knowledge and attitudes of different health care workers and laypeople toward the donation and transplantation procedure.Subjects and methodsA survey consisting of questions regarding brain death diagnosis, legal organization or organ donation, and the transplantation procedure were sent to participants: 56 intensive care unit (ICU) doctors, 76 ICU nurses, 188 sixth-year medical students, and 320 general practitioners (GPs). Laypeople were also asked to complete the survey.ResultsThe majority of participants reported being aware of legal regulations for organ donation in Hungary (88.5%). Roughly 25% of GPs and 60% of laypeople were unaware of the opt-out system effective in the country. Less than one-third of ICU physicians (26.9%) and nurses (34.7%) were able to list the organs that may be transplanted from a deceased donor; GPs (22.4%) and medical students (20%) performed even worse on this item. The willingness of ICU specialists (57%) and ICU nurses (45%) to support donating their own organs was moderate.ConclusionsThe results of this survey indicate a need for graduate and postgraduate education and regular teaching programs regarding organ donation and transplantation. More active use of modern media is proposed to improve public awareness and acceptance of organ donation.     

Carcinoma intraductal de próstata concomitante y respuesta al tratamiento hormonal en el carcinoma de próstata metastásico

Introduction and objectiveMost prostate cancers are classified as acinar adenocarcinoma. Intraductal carcinoma of the prostate (IDC-P) is a distinct histologic entity that is believed to represent retrograde spread of invasive acinar adenocarcinoma into prostatic ducts and acini.We have analyzed the impact of IDC-P in hormonal naïve and castration resistant metastatic prostate cancer patients.Patients and methodsWe retrospectively evaluated 118 metastatic castration resistant prostate cancer (mCRPC) patients who were initially diagnosed with distant metastases from May 2010 to September 2018. Group 1 patients included 81 metastatic PCa patients with acinar adenocarcinoma and Group 2 included 37 metastatic PCa patients with IDC-P.ResultsMean age at presentation was 76 years (IQR 73.4-78.7) in group 1 and 74 years (68.5-80.6) in group 2. Mean PSA at diagnosis was 619 ng/mL (IQR 85-1113) and 868 ng/mL (IQR 186-1922), respectively. Time to castration resistance was 24.7 months (IQR 16.7-32.7) in group 1 and 10.2 months (IQR 4.2-16.2) in group 2 (p = 0.007). Time to progression in CPRC patients was: 10.6 months (IQR 5.6-15.6) and at 6.2 months (3.2-9.2), respectively (p = 0.05). Overall survival was 57.9 months in group 1(CI 95% 56.4-59.5) and 38 months (CI 95% 19.9-48.06) in group 2 (p = 0.001). In the multivariate analysis, adenocarcinoma subtype was statistically significant p 0.014, CI 95% (HR 0.058, 0.006-0.56).ConclusionsIDC-P seems to be a subtype of prostate cancer that is associated with a shorter response to hormonal treatment when compared to acinar adenocarcinoma in metastatic patients. New drugs in CRPC scenario as abiraterone and enzalutamide also obtained less response in IDC-P patients. In daily clinical practice it might be interesting to take into account that patients with IDC-P may present shorter responses to first and second line hormonal treatments.     

Estudio de las infecciones relacionadas con la asistencia sanitaria tras la realización de cistectomía radical

Introduction and objectiveRadical cystectomy is a complex surgery with a high rate of complications including infections, which lead to increased morbidity and mortality, longer hospital stay and higher costs. The aim of this work is to evaluate health care-associated infections (HAIs) in these patients, as well as associated microorganisms, antibiotic resistance profiles and risk factors.Material and methodsProspective study from 2012 to 2017. Epidemiologic variables, comorbidities and surgical variables are collected. The microorganisms involved and antibiotic susceptibility patterns are analyzed.Results122 patients. Mean age 67 (SD:18,42). Mean hospital stay 23.5 days (18.42). HAIs rate of 45%, with predominant urinary tract infections (43%) and surgical wound infections (31%). Positive cultures in 78.6% of cases. Increased isolation of Enterococcus (18%) and Escherichia coli (13%). Forty-three percent of microorganisms were resistant to amoxicillin/ampicillin, 23% to beta-lactamases and 36% to quinolones. Empirical treatment was adequate in 87.5%. Hospital stay is increased (17 days, p< 0.05) due to HAIs. Lower rate of infectious complications in the laparoscopic vs. open approach (p< 0.001) and in orthotopic vs. ileal conduit diversion (p = 0.04)ConclusionsWe found a high rate of HAIs in our radical cystectomy series, with predominant urinary tract and surgical wound infections. E.coli and Enterococcus spp. are the most frequently isolated microorganisms, with high rates of resistance to some commonly used antibiotics.     

Utilidad de la quimioterapia neoadyuvante en el carcinoma vesical músculo invasivo no metastásico

ObjectiveWe analyzed the profile of patients who were candidates for neoadjuvant chemotherapy (NACT) in stage pT2-4aN0M0, the tolerability and adherence of our cisplatin-based protocol and oncological outcomes.Material and methodsRetrospective observational cohort study including patients diagnosed with muscle-invasive bladder carcinoma treated with NACT. Clinical, histopathological, therapeutic and evolutionary characteristics of the patients were analyzed. The use of NACT was evaluated by the complete response in the surgical specimen (pT0). This and other pathological factors were related to overall survival and progression-free survival.ResultsWe included 90 patients with muscle-invasive bladder carcinoma (clinical stage T2a-T4aN0M0) who received a cisplatin-based NACT regimen between January 2011 and December 2018, prior to radical surgery. Forty percent of patients presented an adverse reaction, with a compliance with the NACT regimen of 92.2%. There were no deaths related to systemic treatment and no adverse reaction to treatment made radical cystectomy impracticable. After performing radical cystectomy, the presence of complete response (pT0) was observed in 20 patients (21%), lower stage in the surgical specimen (<pT2) in 36 patients (40%), positive surgical margins in 7 patients (8%), lymph node involvement (N1) in 16 patients (17.8%). A shorter time to progression was observed in the group of patients who did not achieve a complete pathological response (53 months vs. 83.1 in pT0 patients, P = 0.012), in patients with lymph node involvement compared to pN0 (65.4 vs. 28, 2 months, P = 0.014) and in those with positive surgical margins compared to those with tumor-free margins (63.5 vs. 8.5 months, P = 0.021).ConclusionThe adequate selection of patients with muscle-invasive bladder carcinoma has shown a good tolerance to NACT, with a high compliance rate prior to RC. The improvement in the complete response rate implies a greater survival in this group of patients, with lymph node involvement and positive surgical margins being important prognostic factors.     

El manejo de la torsión testicular en Urgencias: lecciones aprendidas de las reclamaciones por responsabilidad profesional médica

ObjectiveTo evaluate emergency care for testicular torsion in medical professional liability claims.MethodClaims related to testicular torsion from 2000 to 2018 were located. The assistance provided and the association with medical professional liability were analyzed.ResultsEighty complaints were identified, testicular pain was reported in 83.75% of first consultations, with a mean evolution time of 15.5 h. The mean time to diagnosis was 7.98 days. The first consultation was at the hospital in 75.1% of cases, but an ultrasound was performed only in 7.5%. When testicular torsion diagnosis was performed, 97.3% had undergone ancillary tests. The medical professional liability was significantly associated with non-criminal proceedings and with less than 6 h of symptoms’ evolution, and, within this subgroup, without undergoing an ultrasound scan.ConclusionsLate consultations, wrong diagnosis and late diagnosis are claimed. When medical professional liability are claimed by means of non-criminal law, the existence of responsibility is frequently considered, even more in those cases when the consultation took place before 6 h of evolution with no ancillary tests having been performed.

Microencapsulation of human spermatozoa increases membrane stability and DNA longevity

The microencapsulation of spermatozoa offers potential benefits for maintaining sperm survival in vitro. The technique has also resulted in the production of offspring in several domestic animal species, but as yet, it has not been successfully applied in human reproductive medicine. This study examined the effect of alginic acid microencapsulation on human sperm membrane integrity (viability) and sperm DNA fragmentation (SDF) following storage for 24 hr at 37°C. The cumulative sperm viability (Log-rank, Mantel–Cox; Chi-square = 114.95, p = .000) and cumulative sperm DNA fragmentation (Log-rank, Mantel–Cox; Chi-square = 187.86, p = .000) of encapsulated spermatozoa were substantially improved when compared to control spermatozoa. Significant differences in the dynamic behaviour of different individuals were only apparent for sperm viability in microencapsulated samples (p = .021) while no significant differences were observed in control spermatozoa (p = .245); the equivalent comparison for SDF showed no differences (control p = .320; microencapsulated p = .432). We present potential scenarios for the use of microencapsulated human spermatozoa in reproductive medicine.     

Trends in burn injury mortality in Spain (1979–2018): Sex-specific age-cohort-period effects

BackgroundPrevious studies about burns mortality are often exclusively based on hospital and burn centre data. National population-based reports on this topic are rather limited. The aim of this study was to analyse sex- and age-specific mortality rates of burns in Spain during the period 1979–2018.MethodsAge-standardised burns mortality rates were calculated from death records and mid-year population data were provided by the Spanish National Statistics Institute. Joinpoint regression analyses were used to identify significant points of change in trends over time and to compute average annual per cent change (AAPC). Age, period and cohort effects were also analysed.ResultsMortality due to burn injury decreased in both sexes between 1979 and 2018: from the first quinquennium of this period up to the last one age-adjusted mortality rates decreased from 1.37 to 0.49 per 100,000 in men and from 0.96 to 0.26 per 100,000 in women.ConclusionsBurns mortality rates in Spain have been decreasing during the last decades. Promotion of primary prevention measures should continue.
