Significant increase of CTX-M-15-ST131 and emergence of CTX-M-27-ST131 Escherichia coli high-risk clones causing healthcare-associated bacteraemia of urinary origin in Spain (ITUBRAS-2 project).

OBJECTIVES: To assess the microbiological characteristics of Escherichia coli causing healthcare-associated bacteraemia of urinary origin (HCA-BUO) in Spain (ITUBRAS-2 project), with particular focus on ESBL producers and isolates belonging to ST131 high-risk clone (HiRC). Clinical characteristics and outcomes associated with ST131 infection were investigated. METHODS: A total of 222 E. coli blood isolates were prospectively collected from patients with HCA-BUO from 12 tertiary-care hospitals in Spain (2017-19). Antimicrobial susceptibility and ESBL/carbapenemase production were determined. ST131 subtyping was performed. A subset of 115 isolates were selected for WGS to determine population structure, resistome and virulome. Clinical charts were reviewed. RESULTS: ESBL-producing E. coli prevalence was 30.6% (68/222). ST131 represented 29.7% (66/222) of E. coli isolates and accounted for the majority of ESBL producers (46/68, 67.6%). The C2/H30-Rx subclone accounted for most ST131 isolates (44/66) and was associated with CTX-M-15 (37/44) and OXA-1 enzymes (27/44). Cluster C1-M27 was identified in 4/10 isolates belonging to subclade C1/H30-R1 and associated with CTX-M-27. Additionally, ST131 isolates showed a high content of other acquired resistance genes, and clade C/ST131 isolates carried characteristic QRDR mutations. They were categorized as uropathogenic E. coli and had higher aggregate virulence scores. ST131 infection was associated with more complex patients, prior use of cephalosporins and inadequate empirical treatment but was not associated with worse clinical outcomes. CONCLUSIONS: ST131 HiRC is the main driver of ESBL-producing E. coli causing HCA-BUO in Spain, mainly associated with the expansion of subclade CTX-M-15-C2/H30-Rx and the emergence of CTX-M-27-C1/H30-R1 (Cluster C1-M27).

HPV knowledge and vaccine acceptability: a survey-based study among parents of adolescents (KAPPAS study).

BACKGROUND: Human papillomavirus (HPV) infection is recognized as one of the major causes of infection-related cancer worldwide. In Spain, the HPV vaccination program started in 2007 and until 2022, it targeted 12-year-old girls. METHODS: This was a cross-sectional, multicenter survey-based research carried out at 24 pediatric offices to describe HPV knowledge and vaccine acceptability in parents of children aged between 9 and 14 years-old in Spain. Parents were randomly selected from the medical records following specific quotas to ensure representativeness. The survey included five sections that aim to collect information about sociodemographic characteristics, knowledge of HPV, knowledge and acceptability of vaccines in general, HPV vaccination knowledge and HPV vaccine acceptability. Each section was constituted by a number of close questions with different answer options. Specific scores were assigned to each possible answer to these questions. Based on these scores, four composite variables were created to assess HPV knowledge, HPV vaccine knowledge, HPV vaccine acceptability and vaccines knowledge and acceptability in general. A latent class analysis was performed to identify different group of respondents according to their HPV vaccine acceptability. RESULTS: A total of 1405 valid surveys were included, with 86.19% of the respondents being mothers. The mean score of HPV knowledge was 28.92 out of 40 (maximum value) (95% CI 28.70-29.20) and the mean score of HPV vaccine acceptability was 3.37 out of 5 (maximum value). One third of parents still need more information to take a final decision about HPV vaccination in their children. Parents perceived that females were more likely to become infected than males and tended to associate HPV infection mainly with cervical cancer, showing a. a lack of information about other HPV-related diseases affecting males. CONCLUSIONS: This study results highlight the need for future actions and educational initiatives to raise awareness of HPV consequences in both genders and to contribute to achieving the elimination of HPV-related diseases beyond cervical cancer.

Factors influencing HPV knowledge and vaccine acceptability in parents of adolescent children: results from a survey-based study (KAPPAS study).

Human Papillomavirus (HPV) is one of the most common sexually transmitted infections associated with a wide range of diseases and cancers that may affect both genders. Since 2007, the Spanish National Immunization Program includes HPV vaccination, and currently it only targets 12-year-old girls. The objective of our study is to assess differences in the knowledge of HPV and HPV vaccine acceptability according to different factors, and to identify the role of different sources of information. A cross-sectional, multicenter survey research was carried out in twenty-four pediatric offices in Spain, and included parents of children aged 9 to 14 years old. 1,405 valid survey-responses were considered for the analysis. Parental awareness of HPV and HPV vaccine, as well as vaccine acceptability, are still strongly associated with child gender (girls) and age (12-14 years old). HPV knowledge and HPV vaccine acceptability are related to parental gender, HPV vaccination status and having at least one daughter. Parents who consulted a healthcare source to obtain further information about HPV had greater HPV and HPV vaccine knowledge and acceptability. HPV and HPV vaccine awareness and acceptability are strongly associated with child gender and age, which correlates with the current immunization program.

Influenza and Measles-MMR: two case study of the trend and impact of vaccine-related Twitter posts in Spanish during 2015-2018.

Social media, and in particularly Twitter, can be a resource of enormous value to retrieve information about the opinion of general populaton to vaccines. The increasing popularity of this social media has allowed to use its content to have a clear picture of their users on this topic. In this paper, we perform a study about vaccine-related messages published in Spanish during 2015-2018. More specifically, the paper has focused on two specific diseases: influenza and measles (and MMR as its vaccine). By also including an analysis about the sentiment expressed on the published tweets, we have been able to identify the type of messages that are published on Twitter with respect these two pathologies and their vaccines. Results showed that in contrary on popular opinions, most of the messages published are non-negative. On the other hand, the analysis showed that some messages attracted a huge attention and provoked peaks in the number of published tweets, explaining some changes in the observed trends.

HPV knowledge and vaccine acceptance among European adolescents and their parents: a systematic literature review.

BACKGROUND: Since the introduction of HPV vaccines, several studies have been conducted in different countries to assess HPV knowledge and vaccine acceptance. The aim of this study was to perform a systematic literature review to summarize results and identify factors associated with HPV knowledge and vaccine acceptance in adolescents and their parents and to compile the measurement tools used in the published research studies performed in European countries where HPV is licensed. METHODS: A systematic literature review was conducted for studies published between January 1st 2006 and December 31st 2017. RESULTS: Seventy non-interventional studies performed in 16 European countries met the inclusion criteria. Thirty-eight of them reported data on HPV knowledge and 40 reported data on HPV vaccine acceptance. Further, 51.8% of adolescents (range 0% to 98.6%) and 64.4% of parents (range 1.7% to 99.3%) knew about HPV infection. Insufficient information and safety concerns were the main barriers to vaccination acceptance. CONCLUSION: HPV knowledge and vaccine acceptance are still modest and vary widely between studies across EU countries. Coordinated efforts should be made to provide the relevant population with information for informed decision-making about HPV vaccination.

The Influence of Patient Experience with Healthcare on the Health-Related Quality of Life of People Living with HIV: An Observational Cross-Sectional Survey.

INTRODUCTION: Patient experience is central to the quality of healthcare delivery, showing positive associations with several outcome measures. The main objectives of this study are to analyze the influence of patient experience on the health-related quality of life in people living with HIV and the role played by treatment complexity and clinical care. METHODS: We conducted a cross-sectional survey with 467 patients with HIV. We used the Instrument for Evaluation of the Experience of Chronic Patients and the Health-related Quality of Life Questionnaire (EQ-5D-5L). We analyzed a predictive model through the partial least squares (PLS) method. RESULTS: The patient self-management scores showed the highest positive relationship with the patient's health-related quality of life (ß = 0.24, ß = 0.32, p < 0.0001). Patients' treatment complexity had a negative influence on health-related quality of life (ß = - 0.21, ß = - 0.28, p < 0.0001). The complexity of clinical care had negative effects on health-related quality of life, both directly (ß = - 0.37, ß = - 0.19, p < 0.0001) and through its negative influence on the productive interactions with healthcare professionals (ß = - 0.21, p < 0.0001) and patient self-management factors (ß = - 0.21, p < 0.0001). The effects of patient experience dimensions on their health-related quality of life were higher in people living with HIV > 50 years old (p < 0.05). CONCLUSIONS: Patient experience mainly influenced the health-related quality of life of older people living with HIV. The treatment and clinical care complexity played an important role in degrading the patients' experience and their quality of life. More integrated care would benefit the health-related quality of life of people living with HIV. FUNDING: This project was funded by Merck Sharp & Dohme, Spain.

Changes in Liver Steatosis After Switching From Efavirenz to Raltegravir Among Human Immunodeficiency Virus-Infected Patients With Nonalcoholic Fatty Liver Disease.

BACKGROUND: Antiretroviral drugs with a lower potential to induce hepatic steatosis in human immunodeficiency virus (HIV) infection need to be identified. We compared the effect of switching efavirenz (EFV) to raltegravir (RAL) on hepatic steatosis among HIV-infected patients with nonalcoholic fatty liver disease (NAFLD) receiving EFV plus 2 nucleoside analogues. METHODS: HIV-infected patients on EFV plus tenofovir/emtricitabine or abacavir/lamivudine with NAFLD were randomized 1:1 to switch from EFV to RAL (400 mg twice daily), maintaining nucleoside analogues unchanged, or to continue with EFV plus 2 nucleoside analogues. At baseline, eligible patients should show controlled attenuation parameter (CAP) values ≥238 dB/m. Changes in hepatic steatosis at 48 weeks of follow-up over baseline levels were measured by CAP. RESULTS: Overall, 39 patients were included, and 19 of them were randomized to switch to RAL. At week 48, median CAP for the RAL group was 250 (Q1-Q3, 221-277) dB/m and 286 (Q1-Q3, 269-314) dB/m for the EFV group (P = .035). The median decrease in CAP values was -20 (Q1-Q3, -67 to 15) dB/m for the RAL arm and 30 (Q1-Q3, -17 to 49) dB/m for the EFV group (P = .011). CAP values <238 dB/m at week 48 were observed in 9 (47%) patients on RAL and 3 (15%) individuals on EFV (P = .029). CONCLUSIONS: After 48 weeks, HIV-infected individuals switching EFV to RAL showed decreases in the degree of hepatic steatosis, as measured by CAP, compared with those continuing with EFV. In addition, the proportion of patients without significant hepatic steatosis after 48 weeks was greater for those who switched to RAL. CLINICAL TRIALS REGISTRATION: NCT01900015.

Impacto presupuestario de una combinación a dosis fija de efavirenz-emtricitabina-tenofovir para tratamiento de pacientes infectados por el virus de la inmunodeficiencia humana tipo 1 / Budget impact of a set-dose combination of efavirenz-emtricitabine-tenofovir in the treatment of patients infected with HIV-1

Objetivo: Estimación del impacto presupuestario de la utilización de la combinación fija de efavirenz-emtricitabina-tenofovir en el tratamiento de pacientes infectados por el virus de la inmunodeficiencia humana tipo 1 (VIH-1) para el Sistema Nacional de Salud en España, y evaluación de la repercusión para cada comunidad autónoma en el año 2008. Métodos: Se ha desarrollado un modelo de impacto presupuestario con los costes farmacológicos de las alternativas terapéuticas actualmente disponibles, a partir de las pautas recomendadas por GeSida para el tratamiento de la infección por el VIH-1. En el modelo se han definido 5 posibles escenarios en los que se asumen diferentes posibilidades de sustitución de las distintas asociaciones terapéuticas por la combinación efavirenz + emtricitabina + tenofovir. Resultados: La inversión por paciente en el ámbito nacional supone un coste de 7.989 € en el escenario base (sin considerar disponibilidad de la combinación efavirenz-emtricitabina-tenofovir) y de 7.997, 8.424, 7.830, 8.375 y 8.527 € para los escenarios 1 (sustitución de pautas con efavirenz, emtricitabina, tenofovir o efavirenz, lamivudina, tenofovir), 2 (sustitución de pautas con efavirenz), 3 (sustitución de pautas con tenofovir), 4 (sustitución de pautas con tenofovir o zidovudina) y 5 (sustitución total), respectivamente, lo que se traduce en incrementos respecto al escenario base del 0,11, 5,45, —1,99, 4,83 y 6,73 % para los escenarios 1, 2, 3, 4 y 5, respectivamente. Conclusión: La utilización de la combinación fija de efavirenz-emtricitabina-tenofovir en el tratamiento de pacientes adultos infectados por el VIH-1 conllevaría ligeros incrementos o incluso ahorros presupuestarios, con disminución del número de tomas diarias, lo que podría mejorar la calidad de vida de los pacientes, el cumplimiento y la adherencia al tratamiento (AU)

Objective: Estimate the budgetary impact of using a set-dose combination of efavirenz-emtricitabine-tenofovir for the Spanish health care system’s treatment of patients infected with HIV-1, while evaluating repercussions for each autonomous community in 2008.Methods: We developed a budgetary impact model with pharmacological costs for the different currently available treatment options, based on GeSida’s recommended guidelines for treating HIV-positive patients. The model defi nes fi ve possible scenarios in which various possibilities for substituting different drug cocktails with the efavirenz-emtricitabine-enofovir combination are contemplated.Results: The investment per patient on a national level amounts to €7,989 in the base scenario (without considering the availability of the efavirenz-emtricitabine-tenofovir combination) and to €7,997, €8,424, €7,830, €8,375 and €8,527 for scenario 1 (substitution of recommended drugs with efavirenz, emtricitabine and tenofovir or efavirenz, lamivudine and tenofovir); scenario 2 (substitution of recommended drugs with efavirenz); scenario 3 (substitution of recommended drugs with tenofovir); scenario 4 (substitution of recommended drugs with tenoforvir or zidovudine) and scenario 5 (total substitution), respectively. Compared with the base scenario this means increments of 0.11 %, 5.45 %, —1.99 %, 4.83 % and 6.73 % for scenarios 1, 2, 3, 4 and 5.Conclusion: Use of a set combination of efavirenz, emtricitabine and tenofovir to treat adult patients with the HIV-1 virus would lead to slight surpluses or even budgetary savings by decreasing the number of daily doses, which could increase patients’ quality of life and help them stay on the treatment properly (AU)
