Human papillomavirus genotype distribution and human papillomavirus 16 and human papillomavirus 18 genomic integration in invasive and in situ cervical carcinoma in human immunodeficiency virus-infected women.

BACKGROUND: Women infected with human immunodeficiency virus (HIV) are at increased risk of developing precancerous and cancerous lesions in cervix because of persistence of oncogenic human papillomavirus (HPV) infection. Scarce information about the HPV genotypes attributed to cervical cancer in the HIV-infected population is available, especially in countries with a low prevalence of this pathology. OBJECTIVE: The objective of the study was to assess the prevalence and distribution of HPV types, and the viral integration of HPV-16 and HPV-18 in cervical squamous cell carcinoma of HIV-infected and HIV-negative women. METHODS: A total of 140 formaldehyde-fixed paraffin-embedded specimens from 31 HIV-infected and 109 matched HIV-negative women, with a diagnosis of in situ or invasive cervical carcinoma, were identified between 1987 and 2010 from different hospitals of the Barcelona area, Spain. Human papillomavirus genotyping and integration were analyzed by standardized polymerase chain reaction. RESULTS: Similar prevalence and distribution of HPV genotypes were detected in cervical cancers (in situ and invasive) regardless of HIV condition. The most common types were as follows: HPV-16 (58% in HIV-positive vs 72% in HIV-negative) and HPV-33 (16% vs 8%). In invasive cervical carcinoma, HPV-18 was significantly more prevalent in HIV-positive women (14% vs 1%; P = 0.014). The proportion of samples with integrated forms of HPV-16 (39% vs 45%) and HPV-18 (50% vs 50%) was similar in both groups. CONCLUSIONS: The prevalence and distribution of principal HPV types involved in the carcinogenesis process of the cervix were similar in HIV-infected and noninfected women, although a tendency toward a lower HPV-16 and a higher HPV-18 prevalence in invasive cervical carcinoma was detected in HIV-positive women. Similar percentage of HPV-16 and HPV-18 viral integration was found in formaldehyde-fixed paraffin-embedded specimens of cervical cancer regardless of the HIV infection status.

Smoked cocaine in socially-depressed areas.

BACKGROUND: The main objectives of this study are to describe the smoked cocaine user's profile in socially-depressed areas and their needs from a harm-reduction perspective, to investigate their use of smoking crack and compare the acute effects between injecting and smoking consumption. METHODS: The study took place in SAPS, Barcelona, Spain. Two focus group sessions were undertaken with a total of 8 drug users. Secondly, the 8 participants answered a structured questionnaire and in the course of the sessions, as a snowball activity, were trained to survey 6 other crack smokers. RESULTS: We obtained 56 questionnaires. The majority of participants were from non-European Community countries (62.69%), 70.2% of participants referred to sharing the smoking equipment. The most frequent symptoms reported during smoked cocaine were mydriasis (83.33%)), perspiration (72.92%) and compulsive object search (70.83%) During the group sessions, participants said that smoked cocaine is much more addictive than injected cocaine and causes more anxiety. Participants also reported the difficulty of changing from injected use to smoked use, due to the larger amount of cocaine needed to reach the same effects as when having injected. CONCLUSIONS: We can conclude that the research, focused on achieving greater knowledge of the smoked cocaine user's profile, their usage of smoking crack, consumption patterns and acute effects, should be incorporated into substance misuse interventions.

[Evaluation of a home-based intervention in heart failure patients. Results of a randomized study]. / Evaluación de una intervención domiciliaria en pacientes con insuficiencia cardíaca. Resultados de un estudio aleatorizado.

INTRODUCTION AND OBJECTIVES: Home-based interventions after hospital discharge in patients with heart failure (HF) have been shown to decrease readmission and mortality rates. The primary aim of this study was to determine the effect of a home-based educational intervention carried out by nursing staff on the readmission rate, emergency department visits, and healthcare costs. PATIENTS AND METHOD: Patients hospitalized with systolic HF were randomly assigned to receive either usual care or a single home-based educational intervention 1 week after discharge. RESULTS: Between July 2001 and November 2002, 70 patients entered the study: 34 in the intervention group and 36 in the control group. During the 6-month follow-up, there were fewer unplanned readmissions in the intervention group than in the control group (0.09 vs 0.94; P<.001), fewer emergency department visits (0.21 vs 1.33; P<.001), and fewer out-of-hospital deaths (2 vs 11; P<.01). Costs were also significantly lower in the intervention group (difference, ; 1190.9; P<.001). Moreover, patient-perceived health status, as indicated by scores on a quality-of-life questionnaire, increased significantly in the intervention group. CONCLUSIONS: In a cohort of patients with systolic HF who received a home-based educational intervention there were significant reductions in the unplanned readmission rate, mortality, and healthcare costs, and better quality of life. Some limitations of the study warrant validation of the resultats in further studies.

Compliance with local guidelines for antibiotic prophylaxis in surgery.

OBJECTIVES: To describe the development and implementation of a local protocol for antibiotic prophylaxis in surgery and to assess compliance with these guidelines using a computer-based system. DESIGN: One 5-week prospective period (phase 1) followed by three 1-week, cross-sectional assessments (phases 2, 3, and 4). SETTING: Pharmacy of a 350-bed acute care teaching hospital in Barcelona, Spain. METHODS: In phase 1, 395 forms for antibiotic prescribing delivered to the pharmacy were reviewed. Nonadherence was defined as the prescription of an antibiotic (or doses) different from what the protocol specified. In phases 2, 3, and 4, antibiotic prescribing forms for all elective procedures (630 patients) performed during 1-week periods were analyzed. RESULTS: A total of 1,047 patients (mean age, 58.9 +/- 17.3 years) were included. Cefazolin was administered in 41% of procedures. Overall compliance with antibiotic prescribing forms was 83.3%. There was a statistically significant increase in compliance with guidelines throughout the four phases of the study, from 80.3% in phase 1 to 87.8% in phase 4 (P < .042), as well as adherence to completing forms for surgical procedures, from 51% in phase 2 to 77.6% in phase 4 (P < .001). The main reason for non-adherence was that some procedures had not been included in the protocol in phase 2. CONCLUSION: Surgeons sensitized to the implementation of local antibiotic prophylaxis guidelines showed a high degree of compliance with them, using both the procedure established for antibiotic prescribing and the antimicrobials recommended for particular operations
