Assessment of subclinical atherosclerosis in hidradenitis suppurativa.

BACKGROUND: Patients with hidradenitis suppurativa (HS) have an increased prevalence of traditional cardiovascular risk factors. OBJECTIVE: Our aim was to investigate the association between subclinical atherosclerosis, detected by carotid ultrasound, and HS. METHODS: A prospective observation and analytical study assessing subclinical atherosclerosis using carotid ultrasound in patients with HS. RESULTS: A total of 62 HS patients and 62 matched controls were studied. Diabetes mellitus (22.6% vs. 6.5%, P = 0.020), hypertension (41.9% vs. 12.9%, P < 0.001) and metabolic syndrome (MetS) (38.7% vs. 8.1%, P < 0.001) were more common in HS patients. Elevated neutrophil-to-lymphocyte ratio (59.7% vs. 40.3%, P = 0.031), high-sensitivity C-reactive protein (61.1 vs. 29.0%, P < 0.001) and erythrocyte sedimentation rate (46.8% vs. 9.7%, P < 0.001) were more frequent in patients with HS. Subclinical atherosclerosis was present in 30.6% of HS patients and in 16.1% of the controls subjects (P = 0.06). After a logistic regression analysis, elevated age was associated with the presence of subclinical atherosclerosis (P < 0.001), and HS showed a tendency towards this association [adjusted OR (95% CI) 3.8 (0.9-16.0), P = 0.066]. This association was statistically significant between patients 40 years and older [OR (95% CI) 4.9 (1.8-13.1)]. CONCLUSIONS: Our clinical results indicate that patients with HS have a higher prevalence of subclinical atherosclerosis than expected when correcting for traditional risk factors. The findings support the conclusions of previous epidemiological studies.

Biological markers of fertility (inhibin-B) in HIV-infected men: influence of HIV infection and antiretroviral therapy.

OBJECTIVES: Inhibin B (IB) levels and the IB: follicle-stimulating hormone (FSH) ratio (IFR), biomarkers of global Sertoli cell function, show a strong relationship with male fertility. The aim of the study was to examine the prevalence of impaired fertility potential in HIV-infected men and the influence of antiretroviral therapy (ART) on fertility biomarkers. METHODS: A cross-sectional study with sequential sampling was carried out. A total of 169 clinically stable patients in a cohort of HIV-infected men undergoing regular ambulatory assessment in a tertiary hospital were included. The mean [± standard deviation (SD)] age of the patients was 42.6 ± 8.1 years, all were clinically stable, 61.5% had disease classified as Centers for Disease Control and Prevention (CDC) stage A, and were na?ve to ART or had not had any changes to ART for 6 months (91.1%). Morning baseline IB and FSH concentrations were measured using an enzyme-linked immunosorbent assay (ELISA) and an electrochemiluminescent immunoassay (ECLIA), respectively. A multivariate logistic regression model was used to identify factors associated with impaired fertility, defined as IB < 119 pg/mL or IFR < 23.5. RESULTS: The mean (± SD) IB level was 250 ± 103 pg/mL, the median [interquartile range (IQR)] FSH concentration was 5.1 (3.3-7.8) UI/L and the median (IQR) IFR was 46.1 (26.3-83.7). The prevalence of impaired fertility was 21.9% [95% confidence interval (CI) 16.3-20.7%]. Negative correlations of body mass index and waist: hip ratio with FSH and IB levels were observed (P < 0.01), while a sedentary lifestyle and previous nevirapine exposure were associated with a decreased risk of IB levels ≤ 25th percentile in multivariate analysis. Only older age, as a risk factor, and sedentary lifestyle, with a protective effect, were independently associated with impaired fertility in multivariate analysis. CONCLUSIONS: Global testicular Sertoli cell function and fertility potential, assessed indirectly through serum IB levels and IB: FSH ratio, appear to be well maintained in HIV-infected men and not damaged by ART.

Empirical monotherapy with meropenem or combination therapy: the microbiological point of view.

The increase in the number of clinical isolates of multiresistant Enterobacteriaceae and Pseudomonas aeruginosa raises problems in decision-making on empirical treatments for severe Gram-negative bacilli-associated infections. The aim of our study is to determine the resistance of meropenem in our setting and the co-resistance of a combination of this compound with two antibiotics from different families: amikacin and ciprofloxacin. Between 2009 and 2013, a total of 81,310 clinical isolates belonging to the main species of Enterobacteriaceae and 39,191 clinical isolates of P. aeruginosa isolated in 28 hospitals in the Valencian Community on the South East Mediterranean Coast of Spain were analyzed using data provided by RedMiva (microbiological surveillance network of the Valencian Community). Meropenem resistance in Enterobacteriaceae increased from 0.16 % in 2009 to 1.25 % in 2013. Very few Enterobacteriaceae strains resistant to meropenem were sensitive to ciprofloxacin; in contrast, the combination of meropenem and amikacin led to a marked decrease in the risk of the microorganisms being resistant to both drugs (RR = 34 in 2013). In the case of P. aeruginosa, meropenem resistance also increased (from 14.32 % in 2009 to 24.52 % in 2013). Most meropenem-resistant P. aeruginosa isolates were also resistant to fluoroquinolones. However, the addition of amikacin led to a more than three-fold decrease in the risk of resistance. In our setting, empirical treatment with meropenem is adequate in enterobacterial infections, but poses difficulties when infection due to P. aeruginosa is suspected, in which case a combination of meropenem and amikacin has been shown to have a higher microbiological success rate.

Effectiveness of a programme to reduce the burden of catheter-related bloodstream infections in a tertiary hospital.

The objective of this study was to assess the effectiveness of a catheter-related bloodstream infection (CR BSI) reduction programme and healthcare workers' compliance with recommendations. A 3-year surveillance programme of CR BSIs in all hospital settings was implemented. As part of the programme, there was a direct observation of insertion and maintenance of central venous catheters (CVCs) to determine performance. A total of 38 education courses were held over the study period and feedback reports with the results of surveillance and recommendations were delivered to healthcare workers every 6 months. A total of 6722 short-term CVCs were inserted in 4982 patients for 58 763 catheter-days. Improvements of compliance with hand hygiene was verified at the insertion (87·1-100%, P < 0·001) and maintenance (51·1-72·1%, P = 0·029) of CVCs; and the use of chlorhexidine for skin disinfection was implemented at insertion (35·7-65·4%, P < 0·001) and maintenance (33·3-45·9%, P < 0·197) of CVCs. There were 266 CR BSI incidents recorded with an annual incidence density of 5·75/1000 catheter-days in the first year, 4·38 in the second year [rate ratio (RR) 0·76, 95% confidence interval (CI) 0·57-1·01] and 3·46 in the third year (RR 0·60, 95% CI 0·44-0·81). The education programme clearly improved compliance with recommendations for CVC handling, and was effective in reducing the burden of CR BSIs.

Computed tomography protocols used in staging bronchopulmonary carcinoma: results of a national survey. / Protocolos de tomografía computarizada empleados en la estadificación del carcinoma broncopulmonar: resultados de una encuesta a nivel nacional.

OBJECTIVES: To know the protocols used for staging bronchopulmonary carcinoma by computed tomography in Spain. MATERIAL AND METHODS: Radiologists in 129 hospitals were sent email questionnaires about the organization of their department, scanner type and manufacturer, study extension, techniques employed, and protocol for administering contrast material. RESULTS: A total of 109 hospitals responded with data from 91 teams. Most hospitals were affiliated with a university, and most departments were organized by organ-systems. Scanners were from four manufacturers, and 68% had either 16 or 64 detectors. In 61% of the hospitals, the dose of contrast agent is modified only in patients with extreme body weights, and in 22% the dose is not individualized. Most hospitals do contrast-enhanced studies of the chest and upper abdomen, 42.4% through a single thoracoabdominal acquisition and 55.9% through independent chest and abdominal acquisitions; there was a significant association between these approaches and the scanner manufacturer's protocols and whether the hospital was affiliated with a university. The most commonly used technical parameters were 120kV with dose modulation and variable milliamperage. CONCLUSION: There is very little variability among hospitals in the type of scanner used, the study extension, and the technical parameters used to stage bronchopulmonary carcinoma. Most centers individualize the dose of contrast agent only in extreme weights. There is a broad division between using one or two acquisitions to image the thorax and abdomen, and the number of acquisitions is related to the scanner manufacturer and whether the hospital is affiliated with a university.

Src, a potential target for overcoming trastuzumab resistance in HER2-positive breast carcinoma.

BACKGROUND: Src is a non-receptor tyrosine kinase involved in signalling and crosstalk between growth-promoting pathways. We aim to investigate the relationship of active Src in response to trastuzumab of HER2-positive breast carcinomas. METHODS: We selected 278 HER2-positive breast cancer patients with (n=154) and without (n=124) trastuzumab treatment. We performed immunohistochemistry on paraffin-embedded tissue microarrays of active Src and several proteins involved in the PI3K/Akt/mTOR pathway, PIK3CA mutational analysis and in vitro studies (SKBR3 and BT474 cancer cells). The results were correlated with clinicopathological factors and patients' outcome. RESULTS: Increased pSrc-Y416 was demonstrated in trastuzumab-resistant cells and in 37.8% of tumours that correlated positively with tumour size, necrosis, mitosis, metastasis to the central nervous system, p53 overexpression and MAPK activation but inversely with EGFR and p27. Univariate analyses showed an association of increased active Src with shorter survival in patients at early stage with HER2/hormone receptor-negative tumours treated with trastuzumab. CONCLUSIONS: Src activation participates in trastuzumab mechanisms of resistance and indicates poor prognosis, mainly in HER2/hormone receptor-negative breast cancer. Therefore, blocking this axis may be beneficial in those patients.

A comparison of early diagnostic utility of Alzheimer disease biomarkers in brain magnetic resonance and cerebrospinal fluid.

INTRODUCTION: The goals of this study were to compare the early diagnostic utility of Alzheimer disease biomarkers in the CSF with those in brain MRI in conditions found in our clinical practice, and to ascertain the diagnostic accuracy of both techniques used together. METHODS: Between 2008 and 2009, we included 30 patients with mild cognitive impairment (MCI) who were examined using 1.5 Tesla brain MRI and AD biomarker analysis in CSF. MRI studies were evaluated by 2 radiologists according to the Korf́s visual scale. CSF biomarkers were analysed using INNOTEST reagents for Aß1-42, total-tau and phospho-tau181p. We evaluated clinical changes 2 years after inclusion. RESULTS: By 2 years after inclusion, 15 of the original 30 patients (50%) had developed AD (NINCDS-ADRA criteria). The predictive utility of AD biomarkers in CSF (RR 2.7; 95% CI, 1.1-6.7; P<.01) was greater than that of MRI (RR 1.5; 95% CI 95%, 0.7-3.4; P<.2); using both techniques together yielded a sensitivity and a negative predictive value of 100%. Normal results on both complementary tests ruled out progression to AD (100%) within 2 years of inclusion. CONCLUSIONS: Our results show that the diagnostic accuracy of biomarkers in CSF is higher than that of biomarkers in MRI. Combined use of both techniques is highly accurate for either early diagnosis or exclusion of AD in patients with MCI.

Impact of vitamin D insufficiency on insulin homeostasis and beta cell function in nondiabetic male HIV-infected patients.

OBJECTIVES: Vitamin D is thought to play a role in glucose homeostasis and beta cell function. Our aim was to examine the impact of plasma 25-hydroxyvitamin D [25(OH)D] upon in vivo insulin sensitivity and beta cell function in HIV-infected male patients without diabetes. METHODS: A cross-sectional study was carried out involving a cohort of HIV-infected patients undergoing regular assessment in a tertiary hospital. Eighty-nine patients [mean (± standard deviation) age 42 ± 8 years] were included in the study: 14 patients were antiretroviral therapy (ART)-naïve, while 75 were on ART. Vitamin D insufficiency (VDI) was defined as 25(OH)D < 75 nmol/L; insulin sensitivity was determined using a 2-h continuous infusion of glucose model assessment with homeostasis (CIGMA-HOMA), using the trapezoidal model to calculate the incremental insulin and glucose areas under the curve (AUCins and AUGglu, respectively). Beta cell function was assessed using the disposition index (DI). Abdominal visceral adipose tissue (VAT) and hepatic triglyceride content (HTGC) were measured by magnetic resonance imaging (MRI) and 1-H magnetic resonance spectroscopy. Multivariate linear regression analysis was performed. RESULTS: VDI was associated with insulin resistance (IR), as indicated by a higher CIGMA-HOMA index (odds ratio 1.1) [1.01-1.2]. This association was independent of the main confounders, such as age, Centers for Disease Control and Prevention (CDC) stage, ART, lipodystrophy, body mass index, VAT:subcutaneous adipose tissue ratio and HTGC, as confirmed by multivariate analysis (B = 12.3; P = 0.01; r² = 0.7). IR in patients with VDI was compensated by an increase in insulin response. However, beta cell function was lower in the VDI subpopulation (33% decrease in DI). CONCLUSIONS: VDI in nondiabetic HIV-positive male patients is associated with impaired insulin sensitivity and a decrease in pancreatic beta cell function.

[Patients with mild cognitive impairment and a reduced CSF Aß1₋42 protein progress rapidly to Alzheimer's disease]. / Pacientes con deterioro cognitivo leve y reducción de la proteína Aß(1-42) en LCR evolucionan rápidamente a enfermedad de Alzheimer.

INTRODUCTION: Some studies have shown that CSF amyloid-beta 1-42 (Aß1₋42), total tau (T-tau) and tau phosphorylated at threonine 181 (P-tau(181p)) proteins are useful diagnostic markers for distinguishing between clinically stable mild cognitive impairment (MCI) patients and those who will develop Alzheimers disease (AD). Our objective was to test the ability of this technique to discriminate in our cohort of MCI patients, according to the clinical outcome, one year after the lumbar puncture. MATERIAL AND METHODS: A total of 36 MCI patients were included from the local hospital memory clinic. Using INNO-BIA Alzbio-3 reagents from Innogenetics, we measured CSF Aß1₋42, T-tau and P-tau(181p) proteins, and calculated the T-tau/Aß1₋42 y P-tau(181p)/Aß1₋42 ratios. This project was approved by the local ethics committee. RESULTS: One year after the lumbar puncture, 14 MCI patients (38%) developed AD. These patients had lower Aß1₋42 protein levels (285.3 vs 377 ng/ml, P<.02) and higher P-tau(181p)/Aß1₋42 ratio (0,25 vs 0,16, p<.02) than the clinically stable patients. CONCLUSIONS: Our MCI patients with lower Aß1₋42 protein levels and an increased P-tau(181p) /Aß1₋42 ratio progressed quickly to AD. These results may help to identify those MCI patients with a poorer prognosis.

[Epidemiologic study of skin diseases among immigrants in Alicante, Spain]. / Estudio epidemiológico de la patología cutánea en la población inmigrante de Alicante.

BACKGROUND: The influx of a large number of immigrants has altered the sociodemographic profile in Spain. To date, few studies of the skin diseases of immigrants to Spain have been done. OBJECTIVE: To determine the frequency of visits by immigrants to our dermatology clinic, to describe their skin complaints, and to compare them to those of the autochthonous Spanish population. PATIENTS AND METHODS: Prospective, descriptive, analytic study, with an observational substudy of cases and controls from a cross-section of the population. We included all immigrant patients seen at the dermatology clinic between February 2005 and February 2006. RESULTS: Visits by immigrants to the dermatology clinic accounted for 4.1% of the caseload. Their most frequent complaints were eczematous dermatitis (18.4%), viral warts (6.4%), and acne (6.3%). Comparison between the immigrant and autochthonous patient populations showed that eczematous dermatitis, alopecia, melasma, ringworm, scabies, Herpes simplex infection, keratosis pilaris, and xerosis were significantly more frequent among immigrant patients, whereas viral warts, actinic keratosis, hidradenitis suppurativa, lupus, melanoma, and squamous cell carcinoma were significantly less frequent (P < .05). CONCLUSIONS: The immigrant population consults the dermatologist about skin conditions that are already well represented in our routine practice. As the infectious skin diseases of immigrants are also common in our environment, these patients are unlikely to transmit serious tropical skin diseases to the local population.

Biomarkers of Alzheimer's disease in the cerebrospinal fluid of Spanish patients with mild cognitive impairment.

The study of biomarkers in the cerebrospinal fluid (CSF) of patients with mild cognitive impairment (MCI) is a technique used with increasing frequency in the early diagnosis of Alzheimers disease (AD). Our objectiv was to gain an own experience while evaluating the reliability, sensitivity, and reproducibility of this technique in Spanish patients. Thirty-seven patients with MCI and twenty-four control subjects were studied by means of AD biomarker analysis in CSF. xMAP Luminex and INNO-BIA Alzbio3 reagents of Innogenetics were used. The study variables assessed were levels of Aß(1-42), T-tau and P-tau(181p) proteins as well as the ratios of T-tau/Aß(1-42) and P-tau(181p)/Aß(1-42). Samples from nineteen patients were examined twice. Intra-class correlation coefficients for the three biomarkers used showed values higher than 0.95. We observed significant differences between the control group and the MCI groups. In the 6 months following lumbar puncture (LP), eleven (29%) patients with MCI developed AD. These patients showed significant lower levels in Aß(1-42) protein (276.35 ± 78 vs. 367.13 ± 123.49, P < 0.03) and higher ratios (T-tau/Aß(1-42) [0.38 ± 0.2 vs. 0.22 ± 0.14, P < 0.01] and P-tau(181p)/Aß(1-42) [0.27 ± 0.13 vs. 0.16 ± 0.1, P < 0.008]) to those in the same group who remained stable. We obtained similar results to those in the most recent reliable literature with our ROC curves, especially with our P-tau(181p) values and T-tau/Aß(1-42) ratio in order to differentiate between control and AD groups. Our experience showed that the analysis of CSF-AD biomarkers in patients with MCI is reliable, sensitive and reproducible. In our knowledge, this is the first experience in Spanish patients.

Effectiveness of a SARS-CoV-2 infection prevention model in elective surgery patients - a prospective study: does universal screening make sense?

This observational study included patients who underwent pre-operative coronavirus disease 2019 (COVID-19) screening in order to preserve patient safety. Reverse transcriptase polymerase chain reaction (PCR) for severe acute respiratory syndrome coronavirus-2 was performed in 2292 of 8740 surgical procedures, and the incidence of a positive PCR result was 0.0022%. No healthcare-associated infections were detected. There was no difference in overall mortality or length of hospital stay compared with the same period from the previous year. A selective screening strategy to identify patients for PCR testing, based on isolation measures, presurgical clinical-epidemiological assessment and selected major surgeries susceptible to a poor COVID-19-related outcome, is effective and safe for patients and healthcare workers.

[Evaluation of the validity of Ag PANBIO-COVID19 in the diagnosis of SARS-CoV-2 infection in asymptomatic or mildly infected patients]. / Evaluación de la validez del Ag PANBIO-COVID19 de Abbott en el diagnóstico de la infección por SARS-CoV-2 en pacientes asintomáticos o con infección leve.

OBJECTIVE: To assess the validity of SARS-CoV-2 Antigen (Ag) detection for the diagnosis of SARS-CoV-2 infection in mildly infected or asymptomatic patients. METHODS: Observational study to evaluate diagnostic tests. Non-hospitalized patients with indication for diagnostic testing for SARS-CoV-2 infection were included. The diagnostic test to be evaluated was the determination of Ag and as a reference standard to determine the presence of viral RNA the RT-PCR was used. RESULTS: A total of 494 patients were included. Of these 71.5% (353/494) had symptoms and 28.5% (141/494) were asymptomatic (presurgery screening (35/494) and confirmed case-contact (106/494). The overall sensitivity of the Ag test was 61.1% and the specificity was 99.7%. The sensitivity and specificity in the asymptomatic group were 40% and 100% respectively, and in the symptomatic group 63.5% and 99.6% respectively. In turn, the sensitivity and specificity in the group of symptomatic patients varied according to the time of symptom evolution: in patients with recent symptoms, they were 71.4% and 99.6% respectively, while in patients with symptoms of more than 5 days of evolution, they were 26.7% and 100% respectively. In all groups studied, the presence of antigen is associated with a high viral load (Ct<30 cycles). CONCLUSIONS: The use of Ag detection test is not indicated for the diagnosis of SARS-CoV-2 infection in asymptomatic patients or with symptoms of more than 5 days of evolution, but it could be useful in patients with symptoms of 1-5 days of evolution.

Do CSF biomarkers help clinicians predict the progression of mild cognitive impairment to dementia?

There is increasing interest in the value of CSF biomarkers to predict those individuals with mild cognitive impairment who will progress to dementia. However, lumbar puncture is not routine in these patients and biomarker assays are not universally available. To change clinical practice there must be very good evidence that biomarkers are helpful over and above clinical impression. Here we discuss the merits of CSF biomarkers compared with clinicians using simple bedside cognitive tests. Although every biomarker has a superior positive predictive value, most have inferior negative predictive values. When predicting the progression of mild cognitive impairment, the overall misclassification rate by clinicians using bedside cognitive tests is approximately 38% but this could be reduced to approximately 30% by using Abeta1-42 and to 24% with phosphorylated tau or total tau (or a combination of CSF biomarkers). Clinicians and patients together should decide whether this is sufficient to warrant the additional burden of a lumbar puncture, and the cost of the test, or whether further studies are needed before useful and clinically practical conclusions can be reached.

[Current prevalence and characteristics of dermatoses associated with human immunodeficiency virus infection]. / Prevalencia y características de las dermatosis relacionadas con la infección por VIH en la actualidad.

INTRODUCTION: The introduction of highly active antiretroviral therapy has produced a substantial change in the natural history of human immunodeficiency virus (HIV) infection. The frequency of opportunistic infections and AIDS-related cancers has fallen, though new health problems have developed. Likewise, there has been a change in the spectrum of skin diseases now observed in these patients. OBJECTIVE: To analyze the prevalence and characteristics of skin disease in a group of HIV-infected outpatients. METHODS: A cross-sectional, observational study was performed. All patients who attended the day care unit of the infectious diseases department over a 6-month period (May-October, 2003) were offered the possibility of complete dermatologic examination. Epidemiologic and clinical variables were recorded in all participants, together with the findings on examination of the skin. A comparative study was performed, grouping the patients according to CD4-lymphocyte count and antiretroviral treatment. RESULTS: The prevalence of dermatoses in the study patients was 98.3%. The most common conditions were xerosis (114 patients, 37.6%), seborrheic dermatitis (94 patients, 31%), distal subungual onychomycosis (80 patients, 26.4%), and viral warts (65 patients, 21.4%). Grouped by etiology, infectious diseases were the most common (68.6%), followed by inflammatory diseases (47.5%). CONCLUSION: Mucocutaneous lesions continue to be very common in HIV-infected patients, although there has been a qualitative change in the conditions that these patients present.

Etiology of bloodstream infections at a population level during 2013-2017 in the Autonomous Community of Valencia, Spain.

OBJECTIVE: Bloodstream Infections has become in one of the priorities for the antimicrobial stewardship teams due to their high mortality and morbidity rates. Usually, the first antibiotic treatment for this pathology must be empirical, without microbiology data about the microorganism involved. For this reason, the population studies about the etiology of bacteremia are a key factor to improve the selection of the empirical treatment, because they describe the main microorganisms associated to this pathology in each area, and this data could facilitate the selection of correct antibiotic therapy. METHODS: This study describes the etiology of bloodstream infections in the Southeast of Spain. The etiology of bacteremia was analysed by a retrospective review of all age-ranged patients from every public hospital in the Autonomous Community of Valencia (approximately 5,000,000 inhabitants) for five years. RESULTS: A total of 92,097 isolates were obtained, 44.5% of them were coagulase-negative staphylococci. Enterobacteriales was the most prevalent group and an increase in frequency was observed along the time. Streptococcus spp. were the second microorganisms more frequently isolated. Next, the most prevalent were Staphylococcus aureus and Enterococcus spp., both with a stable incidence along the study. Finally, Pseudomonas aeruginosa was the fifth microorganism more frequently solated. CONCLUSIONS: These data constitute a useful tool that can help in the choice of empirical treatment for bloodstream infections, since the knowledge of local epidemiology is key to prescribe a fast and appropriate antibiotic therapy, aspect capital to improve survival.

Evolution and associated factors of hand hygiene compliance in a pediatric tertiary hospital.

BACKGROUND: The objective is to know the evolution of the Degree of Compliance with Recommendations (DCR) on hand hygiene (HH) and its associated factors in the pediatric care areas (PCAs) of a tertiary hospital. METHODS: Observational, cross-sectional study, repeated over time, with direct observation of the DCR on HH during the daily activity of health care workers. Over 13 years, 9226 HH opportunities were observed. Associations between DCR, PCA and other variables (eg, age, sex, and professional position) were examined using χ² and adjusted odds ratios (aOR) with 95% confidence intervals (CI). RESULTS: DCR on HH in 9 PCAs was 64.3% (95% CI, 63.3-65.3), and in the group of non-pediatric areas it was 49.6% (95% CI, 49.1-50.1). The areas with the highest degree of compliance were Oncology 72.8% (95% CI, 69.2-76.4), Neonatology 73.2% (95% CI, 71.3-75.1), and Neonatal intensive care unit 70.0% (95% CI, 67.5-72.6). These were the areas with the strongest association with HH compliance, with aOR:2.8 (95% CI, 2.2-3.6); aOR, 3.0 (95% CI, 2.6-3.6) aOR:2.6 (95% CI, 2.1-3.1), respectively. Other associated factors were the indications "after an activity," aOR, 1.6 (95% CI, 1.5-1.8) and the availability of pocket-size alcohol-based solution, aOR, 2.1(95% CI, 1.9-2.3). CONCLUSIONS: The DCR on HH in PCAs is higher than in other areas, although there is still margin for improvement. We have identified modifiable factors that have an independent association with HH compliance in PCAs. Focusing on modifiable factors will increase compliance with HH with the ultimate goal of reducing healthcare associated infections.

Assessing the short- and long-term prognosis of patients with cirrhosis and acute variceal bleeding.

OBJECTIVE: to evaluate the efficacy of various indicators in predicting short- and long-term survival in patients with cirrhosis and acute variceal bleeding. MATERIAL AND METHODS: prognostic indicators were calculated for a cohort of 201 cirrhotic patients with acute variceal bleeding hospitalized in our center, a third-level teaching hospital. The studied variables were: age, sex, etiology of cirrhosis, endoscopic findings, previous variceal bleeding episodes, human immunodeficiency virus (HIV) infection, hepatocellular carcinoma (HCC), infection during episode, and Child-Turcotte-Pugh (CTP) and Model for End-stage Liver Disease (MELD) scores within 24 hours of bleeding onset. Patients were followed up for at least 6 months until death, liver transplantation, or end of observation. RESULTS: median follow-up was 66.85 weeks (range 0-432.4). The 6-week, 3-month, 12-month and 36-month mortality rates were 22.9, 24.9, 34.3, and 39.8%, respectively. Age >= 65 years, presence of HCC, CTP score >=10, and MELD score >= 18 were the variables associated with mortality in the multivariate analysis. The accuracy of MELD scores as predictors of 6-week, 3-month, 12-month, and 36-month mortality was better than that of CTP scores (c-statistics: 6 week MELD 0.804, CTP 0.762; 3-month MELD 0.794, CTP 0.760; 12-month MELD 0.766, CTP 0.741; 36 month MELD 0.737, CTP 0.717). CONCLUSION: MELD and CTP scores together with age and a diagnosis of hepatocellular carcinoma are useful indicators to assess the short- and long-term prognosis of patients with acute variceal bleeding.

[Assessment of a pharmaceutical interventional programme in patients on medications with renal risk]. / Evaluación de un programa de intervención farmacéutica en pacientes con medicamentos de riesgo renal.

OBJECTIVE: To compare the adaptation of medical prescriptions according to the dosage guides in patients with renal disease, before and after applying a pharmaceutical intervention programme. The secondary objectives were to prepare a guide to dosing in renal disease and to measure the prevalence of prescription of drugs with renal risk. METHOD: Non-randomised, experimental interventional study (before/after) conducted in a general hospital with 800 beds, including hospitalised patients, over the age of 18, with kidney disease and drugs with renal risk prescribed in their pharmacotherapeutic profile. The study was designed to be carried out in two descriptive cross-cutting phases (control group) and a prospective interventional cohort study (intervention group). The primary variable was the percentage non-adaptation according to the stage of renal disease. RESULTS: The study included 185 patients, 88 in the control group and 97 in the intervention group. In the intervention group, the prevalence of non-compliance before and after the intervention was 18.7 % and 2.1 %, representing a statistically significant reduction in non-adaptation of the dose. The costs saved with the pharmaceutical intervention programme were 1,939.63 euro over two months, the average saving per medication intervened amounting to 62.57 euro (CI 95 %, 23.99-101.14 euro; p = 0.02). CONCLUSIONS: The results of the study indicate that the application of a pharmaceutical care model based on the prospective validation of drugs with renal risk, very significantly improved the adaptation of dosing regimens in kidney disease.
