Rasagiline and safinamide as a dopamine-sparing therapy for Parkinson's disease.

OBJECTIVES: To evaluate whether the prescription of monoamine oxidase B inhibitors (MAOB-I), rasagiline and safinamide, contributes to the reduction of levodopa and/or dopamine agonists (DA) dose in order to minimize adverse effects. MATERIALS AND METHODS: A total of 724 patients with Parkinson's disease (PD) have been prospectively included in our database since the year 2000, representing a total of 5124 visits. For each patient and visit, antiparkinsonian treatment was recorded. In the presence of rasagiline and safinamide, we analysed the evolution of levodopa equivalent dose (LED) and LED for DA (LED-DA). RESULTS: The data obtained from the 1664 visits between 2006 and 2010 (321 patients) and the 1709 visits between 2014 and 2018 (403 patients) were analysed in order to assess the impact of the introduction of rasagiline and safinamide, respectively. The annual mean LED remained stable without statistically significant differences. In the first period (impact of rasagiline), the annual mean LED-DA in 2010 was significantly higher than in 2006 (P = 0.001). In the second period (impact of safinamide), the annual mean LED-DA in 2018 was significantly lower than in 2014 (P = 0.002). A repeated-measure analyses of LED-DA including only patients who had taken safinamide showed a statistically significant decrease in LED-DA (P = 0.027). CONCLUSIONS: The introduction of MAOB-I in the overall treatment of PD as part of routine clinical practice has not helped to reduce annual mean LED. However, safinamide reduces annual mean LED-DA and may be linked to a reduction in dose-dependent adverse effects in the long term.

Prophylactic intracameral cefazolin and postoperative topical moxifloxacin after cataract surgery: endophthalmitis risk reduction and safety results in a 16-year study.

PURPOSE: This large retrospective observational study describes the evolution of the rates of postoperative endophthalmitis in cataract surgery in a 16-year period, and compares them before and after two different changes in the prophylaxis protocol of a general hospital in Barcelona, Spain. METHODS: This study included all the phacoemulsification procedures performed from January 2002 to December 2017. In January 2004, intracameral cefazolin at the end of the surgery was added to the prophylaxis protocol of cataract surgery. In January 2011, topical postoperative ofloxacin was replaced by topical moxifloxacin. Cumulative incidences of postoperative endophthalmitis before and after the addition of intracameral cefazolin and the change of ofloxacin by moxifloxacin as postoperative topical treatment were compared. RESULTS: The study included 55,984 surgeries. In the period after the introduction of intracameral cefazolin (2004-2010), the cumulative incidence of endophthalmitis was 0.047% (95% CI 0.019-0.099%), significantly lower than in the previous period. From January 2011 to December 2017, after the postoperative change of topical ofloxacin by moxifloxacin, the cumulative incidence dropped to 0.0037% (95% CI 0.000468-0.01862%), with a relative risk reduction between both periods of 91.3%. CONCLUSION: An intracameral bolus of cefazolin was a very effective prophylaxis of endophthalmitis in cataract surgery. The continuous surveillance and prophylaxis protocol revision over time further reduced the incidence of this complication to extremely low levels.

Agomelatine for Depression in Parkinson Disease: Additional Effect on Sleep and Motor Dysfunction.

Depression and sleep disorders are among the most prevalent nonmotor symptoms of Parkinson disease (PD). Because agomelatine acts as a MT1 and MT2 agonist and as a 5HT2c antagonist, this study was designed to assess the efficacy of agomelatine in treating depressive symptoms in PD patients, and the potential changes both in sleep quality and motor symptoms. Depressed patients with PD were treated with agomelatine for 6 months, and they were evaluated with an array of scales. Completed nocturnal video-polysomnography was performed at baseline and week 12. The efficacy analysis population included 24 patients (12 men). The mean (SD) age was 75.2 (8.3) years. The mean (SD) daily dose of agomelatine was 25.00 (10.43) mg at 24 weeks. No changes in dopamine replacement therapy were made. There was a significant decrease in the 17-item Hamilton Depression Scale score over the course of the study (P < 0.0005). The Scales for Outcomes in Parkinson disease Sleep Questionnaire showed a statistically significant improvement over time in each of its subscales: nighttime sleep (P < 0.005), last month nighttime sleep (P < 0.0005), and daytime sleepiness (P < 0.0005). Surprisingly, changes over time in the motor subscale of Unified Parkinson Disease Rating Scale were statistically significant (P < 0.0005). Periodic limb movements and awakenings measured by polysomnography improved significantly (P < 0.005 and P < 0.05, respectively). We concluded that the use of agomelatine in PD depressed patients may have a considerable therapeutic potential because of its dual action for treating both symptoms of depression and disturbed sleep given its secondary beneficial effects regarding the reduction of extrapyramidal symptoms.

Inflammatory markers as predictors of postoperative adverse outcome in octogenarian surgical patients: an observational prospective study.

INTRODUCTION: The value of inflammatory proteins, interleukin-6 and alpha-1-acid glycoprotein as prognostic factors in elderly people undergoing surgery has not been determined yet. OBJECTIVE: To know whether preoperatively determined inflammatory markers may predict the postoperative outcome of elderly patients undergoing surgery. A scoring system for predicting postoperative morbidity was assessed. METHODS: Hospital-based observational prospective study, with geriatric surgical patients. Preoperative determination of following data: age, gender, scheduled or urgent operation, comorbid diseases, malignancy, physical, mental and nutritional profile. Biochemical markers of inflammation, C Reactive Protein, interleukin-6, and alpha-1-acid glycoprotein were also studied. Preoperative data and postoperative complications were recorded. Binary logistic regression analysis was used to obtain a morbidity risk prediction model. RESULTS: A total of 225 patients were included. Fifty-five patients (24.4%) had postoperative complications, with a mortality rate of 5.3%. Binary logistic regression analysis showed an independent relation between morbidity and the variables malignancy, alpha-1-acid glycoprotein and interleukin-6. The risk (R) of postoperative morbidity adjusted by age was calculated. The model showed a 22.2% sensitivity, 94.8% specificity, and a percentage of correct classification of 78.3%. The area under the ROC curve was 0.781 (95% CI: 0.703-0.858). CONCLUSIONS: An age-adjusted equation for predicting 30-day morbidity that included malignancy, serum IL-6 and alpha 1-acid glycoprotein levels may be useful for risk assessment in octogenarian surgical patients.

[Tecuide. Telemonitoring of patients with dementia and their caregivers]. / Tecuide. Telemonitorización de pacientes con deterioro cognitivo y sus cuidadores.

INTRODUCTION: Given the growing increase in dementia, the need to control these patients, together with the rise of new technologies, makes a change in the current control system imperative. MATERIAL AND METHOD: We have carried out a single-center, clinical study with two groups, a control group of 72 patients/caregivers, who followed the usual controls in consultations, and another telematic group of 76 patients/caregivers, who followed the controls through of the Tecuide platform. The platform had a survey part to detect problems in patients and caregiver claudication, another training part and another chat for direct communication when the caregiver needed it and also served to respond when a problem was detected. RESULTS: After a year of monitoring with the platform we have obtained: a)in patients, reduce behavioral disorders and use of drugs, increase physical exercise and delay institutionalization (DS not found); b)in caregivers there is an improvement in satisfaction with respect to the control of patients with cognitive impairment, and c)in terms of resources, visits to emergency services and dementia consultations have decreased, although admissions to the psychogeriatric unit have increased. CONCLUSIONS: The use of Tecuide as a telematic tool in the control of patients with cognitive impairment does not seem to be inferior to the usual controls in consultations and improves caregiver satisfaction.

Relationship of arterial stiffness and baseline vascular burden with new lacunes and microbleeds: A longitudinal cohort study.

INTRODUCTION: Arterial stiffness may have a significant impact on the development of cerebral small vessel disease (cSVD). PATIENTS AND METHODS: We obtained pulse wave velocity (24-h PWV) by means of ambulatory blood pressure monitoring (ABPM) in patients with a recent small subcortical infarct (RSSI). Patients with known cardiac or arterial embolic sources were excluded. Lacunes, microbleeds, white matter hyperintensities and enlarged perivascular spaces at baseline were assessed in a brain MRI and included in a cSVD score. A follow-up MRI was obtained 2 years later and assessed for the appearance of new lacunes or microbleeds. We constructed both unadjusted and adjusted models, and subsequently selected the optimal models based on the area under the curve (AUC) of the predicted probabilities. RESULTS: Ninety-two patients (mean age 67.04 years, 69.6% men) were evaluated and 25 had new lacunes or microbleeds during follow-up. There was a strong correlation between 24-h PWV and age (r = 0.942, p < 0.001). cSVD was associated with new lacunes or microbleeds when adjusted by age, 24-h PWV, NT-proBNP and hypercholesterolemia (OR 2.453, CI95% 1.381-4.358). The models exhibiting the highest discrimination, as indicated by their area under the curve (AUC) values, were as follows: 1 (AUC 0.854) - Age, cSVD score, 24-h PWV, Hypercholesterolemia; 2 (AUC 0.852) - cSVD score, 24-h PWV, Hypercholesterolemia; and 3 (AUC 0.843) - Age, cSVD score, Hypercholesterolemia. CONCLUSIONS: cSVD score is a stronger predictor for cSVD progression than age or hemodynamic parameters in patients with a RSSI.

Feasibility of a wearable inertial sensor to assess motor complications and treatment in Parkinson's disease.

BACKGROUND: Wearable sensors-based systems have emerged as a potential tool to continuously monitor Parkinson's Disease (PD) motor features in free-living environments. OBJECTIVES: To analyse the responsivity of wearable inertial sensor (WIS) measures (On/Off-Time, dyskinesia, freezing of gait (FoG) and gait parameters) after treatment adjustments. We also aim to study the ability of the sensor in the detection of MF, dyskinesia, FoG and the percentage of Off-Time, under ambulatory conditions of use. METHODS: We conducted an observational, open-label study. PD patients wore a validated WIS (STAT-ONTM) for one week (before treatment), and one week, three months after therapeutic changes. The patients were analyzed into two groups according to whether treatment changes had been indicated or not. RESULTS: Thirty-nine PD patients were included in the study (PD duration 8 ± 3.5 years). Treatment changes were made in 29 patients (85%). When comparing the two groups (treatment intervention vs no intervention), the WIS detected significant changes in the mean percentage of Off-Time (p = 0.007), the mean percentage of On-Time (p = 0.002), the number of steps (p = 0.008) and the gait fluidity (p = 0.004). The mean percentage of Off-Time among the patients who decreased their Off-Time (79% of patients) was -7.54 ± 5.26. The mean percentage of On-Time among the patients that increased their On-Time (59% of patients) was 8.9 ± 6.46. The Spearman correlation between the mean fluidity of the stride and the UPDRS-III- Factor I was 0.6 (p = <0.001). The system detected motor fluctuations (MF) in thirty-seven patients (95%), whilst dyskinesia and FoG were detected in fifteen (41%), and nine PD patients (23%), respectively. However, the kappa agreement analysis between the UPDRS-IV/clinical interview and the sensor was 0.089 for MF, 0.318 for dyskinesia and 0.481 for FoG. CONCLUSIONS: It's feasible to use this sensor for monitoring PD treatment under ambulatory conditions. This system could serve as a complementary tool to assess PD motor complications and treatment adjustments, although more studies are required.

Risk Factors Involved in the High Incidence of Bladder Cancer in an Industrialized Area in North-Eastern Spain: A Case-Control Study.

Bladder cancer (BC) is the most common of the malignancies affecting the urinary tract. Smoking and exposure to occupational and environmental carcinogens are responsible for most cases. Vallès Occidental is a highly industrialized area in north-eastern Spain with one of the highest incidences of BC in men. We carried out a case-control study in order to identify the specific risk factors involved in this area. Three hundred and six participants were included (153 cases BC and 153 controls matched for age and sex): in each group, 89.5% (n = 137) were male and the mean age was 71 years (range 30-91; SD = 10.6). There were no differences between groups in family history, body mass index, or dietary habits. Independent risk factors for CV were smoking (OR 2.08; 95% CI 1.30-3.32; p = 0.002), the use of analgesics in nonsmokers (OR 10.00; 95% CI 1.28-78.12; p = 0.028), and profession (OR: 8.63; 95% CI 1.04-71.94; p = 0.046). The consumption of black and blond tobacco, the use of analgesics in nonsmokers, and occupational exposures are risk factors for the development of BC in this area, despite the reduction in smoking in the population and the extensive measures taken in the last few decades in major industries to prevent exposure to occupational carcinogens.

Systematic review of population-based bladder cancer registries: How criteria heterogeneity affects the comparison of incidences.

BACKGROUND: The population-based registry of bladder cancer (BC) raises specific problems intrinsic to the tumor, as the inclusion of noninfiltrating, potentially malignant and multiple tumors. We performed a systematic review (PRISMA guidelines) of population-based BC registries to obtain information on their geographic areas involved, last dates of real incidence of BC, and rules coding used in BC for uncertain behavior, in situ and multiple tumors. METHODS: Using MEDLINE and Google Scholar, we identified scientific publications of in the last 10 years in English or Spanish, whether they were related to a national or international cancer registry, provided information on registry rules, and provided data on the incidence of BC. RESULTS: After the first screening, a total of 194 references were obtained. After a second analysis, three registries were selected: International Agency for Research on Cancer (IARC) is a world registry providing real incidence of BC in the period 2008-2012. Surveillance, Epidemiology, and End Results (SEER) Program registered incidence until 2017 in more than 90% of the US population. Spanish Network of Cancer Registries (REDECAN) unifies 14 Spanish registries (27.4% of the population) with real incidence data from 2010 to 2015. The coding and inclusion rules have been modified, but currently, most registries include BC in situ and uncertain behavior tumors. Whenever a new case occurs 36 months after a previous diagnosis, SEER registers those as multiple incident cancers in the same location, while IARC and REDECAN only allow one cancer per location during the lifespan of the patient. CONCLUSIONS: Comparison of the incidence of BC among different population-based cancer registries is prone to bias due to the methodological differences regarding the inclusion of carcinomas in situ, indeterminate, and multiple tumors. A good cancer registry could provide better surveillance strategies for BC patients.

Morbimortality after 1321 consecutive CRS + HIPEC procedures: seeking excellence in surgery for peritoneal surface malignancy.

PURPOSE: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) treatment has classically presented a percentage of associated complications that have limited its expansion. The aim of this study is to describe the morbimortality results obtained from a referral center implemented with the support of a governmental health agency and directed by a surgical team experienced in CRS for Peritoneal Surface Malignancies (PSM). METHODS: Data from the Peritoneal Carcinomatosis Program of Catalonia (PCPC) prospective database, including patients who underwent CRS + HIPEC between September 2006 and January 2021, were analyzed. RESULTS: A total of 1151 consecutive patients underwent 1321 CRS + HIPEC procedures. Colonic origin of peritoneal metastasis was the most frequent (47.3%). Median PCI was 7 and most patients had CC0-1 (96.1%). Multivisceral resection was performed in 44% of all patients, 57% required digestive anastomosis. Median hospital stay was 11 days (range 6-144 days). High-grade complications occurred in 20% of all patient, most of them surgical complications. Anastomotic leak occurred in 0.6% of all cases. The overall in-stay and 30-day mortality rate was 0.4%. The low-rate of complications and the high rate of complete CRS were achieved from the beginning of the PCPC. Median overall survival was 54.7 months, with a 5-year survival rate of 47.5%. CONCLUSIONS: Implementation of a CRS + HIPEC referral program for the treatment of PSM with preferably an experienced surgical team enables acceptable rates of severe morbidity (20%) and mortality (< 1%).

NT-proBNP, cerebral small vessel disease and cardiac function in patients with a recent lacunar infarct.

NT-proBNP is produced from both atria and ventricles and it is increased in patients with cardiac disease. NT-proBNP is also associated with cerebral small vessel disease(cSVD) but there are no studies that had carried out a systematic evaluation of cardiac function in this specific setting. We conducted a prospective observational study in 100 patients within 30 days after a recent lacunar infarct by means of brain MRI, 24 h ambulatory blood pressure monitoring, transthoracic echocardiography, and plasmatic NT-proBNP. Global cSVD burden was quantified using a validated visual score (0 to 4) and dichotomized into 2 groups (0-2 or 3-4). Age (73.8 vs 63.5 years) and NT-proBNP (156 vs 76 pg/ml) were increased in patients with SVD 3-4, while daytime augmentation index normalized for the heart rate of 75 bpm (AIx75) (22.5 vs 25.6%) was decreased. The proportion of patients with left atrial enlargement, left ventricular hypertrophy, or septal e' velocity <7 cm/s was not different between both groups. NT-proBNP was increased in patients with left atrial enlargement (126 vs 88 pg/ml). In multivariate analysis, age (OR 1.129 CI 95% 1.054-1.209), daytime AIx75 (OR 0.91 CI 95% 0.84-0.987,) and NT-proBNP (OR 1.007 CI 95% 1.001-1.012,) were independently associated with cSVD score 3-4. In conclusion, as well as in other patients with cSVD we found an association between NT-proBNP and cSVD. This association was independent of cardiac function.

Environmental Factors Involved in the High Incidence of Bladder Cancer in an Industrialized Area in North-Eastern Spain.

Background: Bladder cancer (BC) is the most common of those affecting the urinary tract, and a significant proportion of the cases are attributable to tobacco use as well as occupational and environmental factors. Objective: The aim of this study is to estimate the current incidence of BC in an industrialized area in northeastern Spain and to analyze its time trends over three decades from an ecological perspective. Methods: Patients diagnosed with histologically confirmed primary BC, during 2018-2019, in an area in northeastern Spain (430,883 inhabitants) were included. Crude and age-standardized incidence rates were estimated per 100,000 person-years based on the number of individuals getting their first diagnosis. An exploratory time trend analysis was carried out to describe the evolution in tobacco use and occupational or environmental risk factors and the incidence of BC in the same area from the 1990s. Results: 295 patients were included (age 72.5 ± 10.3 years; 89.8% men). The crude rate was 62.6 (95% CI: 51.9-73.2) for men and 6.8 (95% CI: 3.4-10.3) for women. The annual rate adjusted to the European Standard Population was 85.3 (95% CI:75.0-95.5) for men and 7.0 (95% CI:4.5-9.5) for women. From 1994 to 2018, the prevalence of smokers decreased in men (42.3% to 30.9%) as well as in the active population working in the industry (44.36% to 22.59%). Nevertheless, the car fleet, especially diesel, has increased considerably. The annual mean concentrations of air (PM10, PM2.5, O3, and NO2) and water (nitrates, arsenic, trihalomethanes) pollutants were within the regulatory limit values, but not the maximum levels. Conclusions: The incidence of BC is one of the highest in men but not in women, despite the decrease in tobacco use and industrial activity (perhaps related to high latency after carcinogen exposure cessation) and despite the control of environmental pollution (the maximum regulatory limit probably needs to be lowered). Finally, a similar exposure to the carcinogen would result in a gender-specific differential incidence.

[Evolution of patient colonization with methicillin-resistant Staphylococcus aureus in a skilled nursing facility]. / Evolución de la colonización por Staphylococcus aureus resistente a meticilina en un hospital de media y larga estancia.

BACKGROUND AND OBJECTIVE: Methicillin-resistant Staphylococcus aureus (MRSA) asymptomatic colonization is common in long-term care facilities, but the burden of symptomatic infection appears to be low. It is not usually known whether a patient is colonized at the time of admission to the geriatric facility. Our purpose was to determine the prevalence, characteristics and factors associated with MRSA colonization on admission, and the cumulative incidence of colonization over the following 6 months. PATIENTS AND METHOD: Longitudinal and prospective study conducted over a 6-month period. All patients were screened at admission using nasal and ulcers swabs within the first 24h. Patients were screened also at the end of the study to assess carrier status. RESULTS: The prevalence of MRSA colonization was 7.6% at the entry (25 patients). In the multivariate analysis, advanced age, recent use of antibiotics, prior colonization by MRSA, and peripheral vascular disease were independent risk factors for colonization at admission. With standard precautions, the 6-month cumulative incidence of MRSA colonization was 4.2%. CONCLUSIONS: In our long-term care facility, MRSA colonization at the time of admission was frequent. Few patients were colonized during the study and no episodes of infection were reported. Probably, standard precautions, including hand washing and appropriate barrier procedures during the care of wounds, are the most useful control measures.

Blood pressure in the initial phase of acute ischaemic stroke: evolution and its role as an independent prognosis factor at discharge and after 3 months of follow-up.

BACKGROUND: A prospective observational study was aimed at assessing the role of blood pressure (BP) during the first 24 h from stroke onset on the outcome of acute ischaemic stroke. METHODS: Subjects admitted within the first 3 h from stroke onset were included. Stroke severity was evaluated with the Canadian Stroke Scale (CSS). Functional recovery was defined as a modified Rankin Scale score < or =2. RESULTS: One hundred subjects were included. In a logistic regression model, the independent predictors of poor functional recovery at discharge were: age (OR = 1.12; 95% CI 1.04-1.21; p = 0.0033), non-lacunar stroke subtype (OR = 4.31; 95% CI 1.07-17.31; p = 0.0395), diabetes mellitus (OR = 8.38; 95% CI 1.67-41.95; p = 0.0097), a CSS score at admission < or =8 (OR = 28.64; 95% CI 5.59-146.68; p<0.0001), an average systolic BP during the first 6 h > or =180 mmHg (OR = 13.34; 95% CI 1.34-133.10; p = 0.0272) and a lower diastolic BP average from 6 to 24 h (OR for 5 mmHg increase: 0.57; CI 95% 0.36-0.88; p = 0.0115). Similar results were observed after 3 months of follow-up. CONCLUSION: In ischaemic stroke patients, systolic BP over 180 mmHg in the first 6 h and a decrease of diastolic BP during the 6-24 h from stroke onset were independent predictors of a poor functional recovery.

Reproducibility of the circadian blood pressure pattern in 24-h versus 48-h recordings: the Spanish Ambulatory Blood Pressure Monitoring Registry.

OBJECTIVES: To assess the reproducibility of the circadian blood pressure (BP) pattern over a 48-h period by comparing the first 24 h of ambulatory blood pressure monitoring (ABPM) with the following 24 h and with the mean over 48 h. PATIENTS AND METHODS: Patients undergoing 48-h ABPM within the National ABPM Registry of the Spanish Society of Hypertension, based on 800 Spacelabs 90207 monitors distributed throughout Spain in hypertension units and primary healthcare centres, were included. Between June 2004 and September 2005, 611 valid 48-h ABPM recordings were obtained, 235 corresponded to patients without antihypertensive treatment. RESULTS: The percentages of patients classified as non-dipper for the first 24 h, the second 24 h and the 48-h average were 47, 50 and 48%, respectively. When the first and second 24-h periods were compared, 147 (24%) subjects switched from dipper (D) to non-dipper (ND) or vice-versa. When the first 24-h period was compared to the 48-h average, 66 (11%) subjects switched patterns. The proportions were similar separately for systolic blood pressure (SBP) and diastolic blood pressure (DBP) and between treated and untreated patients. In subjects with poor ABPM reproducibility, night-to-day ratios were of an intermediate value between those of subjects always classified as D or ND. CONCLUSION: Categorization of D or ND based on a single 24-h ABPM is moderately reproducible, since one out of every five patients change profile over the following 24 h. Nevertheless, the use of 48-h ABPM in clinical practice should be assessed according to cost-effectiveness criteria. Night-to-day ratios may be helpful in identifying patients with a stable profile.

[Stratification and degree of control of cardiovascular risk factors in hypertensive Spanish population. Results of the DICOPRESS study]. / Estratificación y grado de control del riesgo cardiovascular en la población hipertensa española. Resultados del estudio DICOPRESS.

BACKGROUND AND OBJECTIVE: Hypertension, together with other contributing risk factors, is a major risk for cardiovascular disease. The aim of this study was to assess the cardiovascular risk in the Spanish hypertensive population according to the 2003 European Society of Hypertension-European Society of Cardiology (ESH/ESC) guidelines criteria and to determine the control rate of the main cardiovascular risk factors (CVRF). PATIENTS AND METHOD: Observational and transversal study including 22,639 patients with essential hypertension, who have been admitted to primary care units and hypertension units in Spain. RESULTS: Dyslipemia (52.1%), diabetes (36.6%) and smoking (22.3%) were the most prevalent CVRF. Cardiovascular risk stratification according to the ESH/ESC guidelines showed that more than 70% patients were considered at high added risk (36.9%) or at very high added risk (35.8%), whereas only 7.6% were classified in the low-risk stratum. Blood pressure was the worst controlled risk factor among hypertensive patients (80.6%). Total cholesterol was also poorly controlled in a high percentage of the analyzed population (66.4%). Diabetes was the best predictor of uncontrolled blood pressure with an odds ratio of 5.25 (99% confidence interval, 4.57-6.06). CONCLUSIONS: Coexistence of several cardiovascular risk factors, as well as the presence of target organ damage and associated cardiovascular conditions in the Spanish hypertensive population, increase the vascular risk, complicate the control in the hypertensive population and show the convenience of using ESH/ESC 2003 guidelines to estimate the cardiovascular risk.

[Impact of a clinical self-evaluation intervention on the appropriateness of hospital stays]. / Impacto de una intervención de autoevaluación clínica sobre la adecuación de la estancia hospitalaria.

AIM: To assess the impact of an intervention on inappropriate hospital stays (IHS) in acute-care hospitals in Catalonia (Spain) with the aim of testing the hypothesis that a simple intervention (adeQhos) reduces the proportion of IHS. METHODS: A pre-test/post-test study was performed through the <> questionnaire. Two intervention groups (internal medicine and general surgery) and 2 control groups (other medical specialities, orthopedics) were compared in 10 acute-care hospitals in Catalonia. The same evaluators assessed appropriateness of hospital stays before and after the intervention, using the Appropriateness Evaluation Protocol. RESULTS: A total of 1,594 pre-test stays and 1,495 post-test stays were reviewed. Of all the stays reviewed (day before discharge), 41.1% were inappropriate. The intervention was applied to 4,613 stays. There was a significant increase of IHS in the medicine control group (from 39.7 to 48.6%), and no decrease in the intervention groups (internal medicine [from 46.7 to 50.6%] or general surgery [from 27.2 to 31.2%]). The correlation between the intensity of the intervention and the difference in IHS before and after the intervention was r = -0.373 (p = 0.106). The intensity of intervention differed among the hospitals. In hospitals with an intensity of intervention > 60%, the proportion of IHS decreased by 10.7 points in internal medicine and by 4.8 points in general surgery, while the proportion of IHS increased in the control groups. CONCLUSIONS: The prevalanece of IHS the day before discharge in the hospitals studied was high (41.1%). No significant decrease in IHS was observed after a low-intensity intervention.

[A new artificial intelligence tool for assessing symptoms in patients seeking emergency department care: the Mediktor application]. / Experiencia de Mediktor®: un nuevo evaluador de síntomas basado en inteligencia artificial para pacientes atendidos en el servicio de urgencias.

OBJECTIVES: To analyze agreement between diagnoses issued by the Mediktor application and those of an attending physician, and to evaluate the usefulness of this application in patients who seek emergency care. MATERIAL AND METHODS: Prospective observational study in a tertiary care university hospital emergency department. Patients with medical problems and surgical conditions (surgery and injuries) who did not require immediate emergency care responded to the Mediktor questions on a portable computer tablet. The software analyzed the answers and provided a list of 10 possible preliminary diagnoses in order of likelihood. The patient and the attending physician were blinded to the list to so that the usual care process would not be altered. The level of agreement between the physician's diagnosis and the Mediktor diagnosis was analyzed. RESULTS: A total of 1015 patients were included; 622 cases were considered valid for study. Cases were excluded if the patients did not meet the inclusion criteria, they did not have a discharge diagnosis, they had a final diagnosis expressed as a symptom or their final diagnosis was not included in the Mediktor database. The physician's diagnosis (the gold standard) coincided with one of the 10 MEDIKTOR diagnoses in 91.3% of the cases, with one of the first 3 diagnoses in 75.4%, and with the first diagnosis in 42.9%. Sensitivity was over 92% and specificity over 91% in the majority of common diagnostic groups; the κ statistic ranged from 0.24 to 0.98. CONCLUSION: The Mediktor application is a reliable diagnostic aid for the most prevalent problems treated in a hospital emergency department. The general public finds it easy to use.

OBJETIVO: Analizar la concordancia entre los diagnósticos emitidos por Mediktor® con el realizado por el médico responsable, así como valorar la utilidad de este dispositivo en pacientes que acuden a un servicio de urgencias (SU). METODO: Estudio observacional prospectivo realizado en el SU de un hospital terciario universitario. A los pacientes con patologías médicas y quirúrgicas (cirugía y traumatología) que no precisaban asistencia médica inmediata se les entregó una tableta digital para responder al interrogatorio de Mediktor®. Según las respuestas, el software adjudicaba un listado de 10 prediagnósticos ordenados por probabilidad, que se ocultaban al paciente y al médico responsable, para no modificar el proceso habitual. Posteriormente se analizó el grado de coincidencia entre el diagnóstico médico y los diagnósticos ofrecidos por Mediktor®. RESULTADOS: 1.015 pacientes fueron incluidos, de los que 622 se consideraron casos válidos para el estudio. Se excluyeron los pacientes que no cumplían los criterios de inclusión, sin diagnóstico al alta, con diagnóstico final expresado como síntoma y aquellos con diagnósticos no incluidos en Mediktor®. Las coincidencias entre el diagnóstico médico (patrón oro) y los diez diagnósticos de Mediktor® fueron de un 91,3%, en los tres primeros diagnósticos de un 75,4% y en el primer diagnóstico de un 42,9%. Según los grupos de diagnósticos más frecuentes, se objetivó una sensibilidad > 92% y una especificidad > 91% en la mayoría de ellos, con un índice kappa que osciló entre el 0,24 y el 0,98. CONCLUSIONES: Mediktor® es una herramienta fiable para ayudar al diagnóstico de las enfermedades más prevalentes de un SU y fácil de utilizar por el público en general.

[Prevalence of hypertension in elderly long-term care residents in Spain. The Geriatric HTA study]. / Prevalencia de hipertensión arterial en ancianos ingresados en centros sociosanitarios y residencias españoles. Estudio Geriatric HTA.

BACKGROUND AND OBJECTIVE: This study aimed to estimate the prevalence of hypertension in elderly long-term care residents in Spain and to describe such population in terms of comorbidity and hypertension treatment and control. PATIENTS AND METHOD: A countrywide cross-sectional study was conducted in May 2003 among long-term care residents aged 65 or more. Patients in palliative care units were excluded. Hypertension was defined in patients who fulfilled at least one of the following criteria: diagnosis of hypertension on the medical record, antihypertensive medication and/or highest blood pressure values during the previous year > or = 140/90 mmHg. RESULTS: Overall, 13,272 subjects - mean age (standard deviation) 82.9 (7.5) years (range: 65-106 years) - were included from 223 centres; 70.6% were women. Almost 2 thirds of patients met at least one hypertension criterion (8,242 patients, 62.1%; 95% confidence interval, 61.3-62.9%). In those patients, other frequent cardiovascular risk factors were obesity (26.3%), diabetes (25.7%) and dislipemia (23.8%). A concomitant diagnosis of dementia, peripheral vascular disease, stroke or congestive heart failure was present in 37.1%, 28.3%, 26.0% and 25.1%, respectively. The proportion of hypertensive patients receiving at least one antihypertensive drug was 69.7%. Diuretics were the most commonly used agents (46.3%), followed by angiotensine converting enzyme inhibitors (34.6%). The latest blood pressure measurement was < 140/90 mmHg in 60.4% of the hypertensive patients. CONCLUSIONS: Elderly long-term care residents in Spain showed a high prevalence of hypertension and other cardiovascular risk factors, and a substantial degree of associated clinical conditions. The proportion of antihypertensive drug therapy was comparable to those reported in similar studies.

[Clustering of cardiovascular risk factors and prevalence of metabolic syndrome in subjects with resistant hypertension]. / Agregación de factores de riesgo cardiovascular y de prevalencia de síndrome metabólico en personas con hipertensión arterial resistente.

BACKGROUND AND OBJECTIVE: The aim of this study was to analyse the clustering of cardiovascular risk factors and the prevalence of metabolic syndrome (MS) in this sample of subjects with resistant hypertension (RH). PATIENTS AND METHOD: One hundred and fifteen subjects with RH were sequentially included. RH was defined as a level of office blood pressure (BP)>or=140/90 mmHg in subjects treated with at least 3 antihypertensive drugs (one of them a diuretic) during at least 2 months and with good compliance. The usual protocol of the Hypertension Unit and ambulatory BP monitoring during 24 h was applied on all the subjects, and an echocardiogram with Doppler was performed on 68 of them. Subjects with a daytime BP>or=135/85 mmHg were defined as pseudoresistant hypertensive. RESULTS: The mean age (standard deviation) was 61 (10) years, and 50 patients (44%) were males. The mean office BP was 166/95 (16/9) mmHg. The daytime BP was 141/83 (15/12) mmHg. Out of the patients, 88 (76.5%) had a family history of cardiovascular disease; 64 (56%) of obesity; 43 (37%) of hypercholesterolemia; 34 (30%) of low high-density lipoprotein cholesterol; 32 (28%) of diabetes mellitus; and 63 (55%) were sedentary. The prevalence of MS was 54%; target organ damage was found in 70 cases (61%), and 44 (38%) had other associated clinical conditions. Out of the subjects with echocardiography, 49 (72%) presented left ventricular hypertrophy. Pseudoresistant hypertension was found in 31 (27%). There were no significant differences in clinical variables between subjects with RH or psudoresistant hypertension. CONCLUSIONS: Patients with RH had high cardiovascular risk, independent of a good control of ambulatory BP, because of the high prevalence of cardiovascular risk factors and MS. An optimal antihypertensive treatment including specific programs for the control of obesity and a sedentary lifestyle are necessary in the management of these patients.
