The effectiveness of nirsevimab in reducing the burden of disease due to respiratory syncytial virus (RSV) infection over time in the Madrid region (Spain): a prospective population-based cohort study.

Introduction: Respiratory syncytial virus (RSV) infection is one of the main causes of morbidity and mortality from lower respiratory tract infections in children under 5 years of age worldwide. Given that, the objective of this study was estimate the effectiveness of nirsevimab (a single-dose, long-acting, human recombinant monoclonal antibody against RSV) over time for the prevention of respiratory episodes treated at different levels of care. Methods: A prospective and dynamic population-based cohort study was performed including infants born between April 1 and December 31, 2023, in the Madrid region who resided there during the follow-up period from October 1, 2023, to February 29, 2024. Infants were considered immunized from the day after receiving one dose (50 or 100 mg) of nirsevimab or nonimmunized individuals if they did not receive any dose. Results: There were 4,100 episodes of primary care, 1,954 hospital emergencies, and 509 admissions, 82 of which required intensive care in the 33,859 participants analyzed. The adjusted effectiveness of nirsevimab in preventing hospitalization due to RSV infection was 93.6% (95% CI: 89.7 to 96.1) at 30 days and 87.6% (95% CI: 67.7 to 95.3) at 150 days. The number needed to treat to prevent one hospitalization were 314.19 (95% CI: 306.22 to 327.99) at 30 days and 24.30 (95% CI: 22.31 to 31.61) at 150 days. The adjusted effectiveness of nirsevimab in avoiding admission to an intensive care unit was 94.4% (95% CI: 87.3 to 97.5) at 30 days and 92.1% (95% CI: 64.0 to 98.3) at 90 days. The adjusted effectiveness of nirsevimab for avoiding primary care consultations and hospital emergency visits was lower. Discussion: Immunization with nirsevimab is an effective measure for reducing the burden of care related to RSV at all levels of care albeit it decreases throughout follow-up. At 150 days it remained high for preventing hospital admissions. Other articles already published have also demonstrated high effectiveness although with preliminary results, short follow-up periods and wide confidence intervals. None have detected a decrease in effectiveness over time. These results can be quite useful in individual infant prevention and in the design of immunization campaigns.

Temporary clamping of the uterine arteries versus coventional technique for the prevention of postpartum hemorrage during cesarean section: a randomized controlled trial study.

BACKGROUND: Cesarean sections are the most common abdominal surgical interventions worldwide, with increasing rates in both developed and developing countries. Postpartum (hemorrhage PPH) during cesarean sections can lead to maternal morbidity, prolonged hospital stays, and increased mortality rates. Although various non-surgical measures have been recommended for PPH prevention, surgical techniques such as uterine artery ligation and embolization have been used to manage PPH effectively. OBJECTIVE: This study aimed to evaluate the effectiveness of a surgical technique based on the temporary bilateral clamping of uterine arteries to reduce blood loss during cesarean sections. METHODS: A longitudinal prospective, randomized, controlled study was conducted with a preliminary population group of 180 patients at the University Hospital Regional de Málaga from November 2023 to January 2024. The study protocol was approved by the Ethics Committee of the Regional University Hospital of Malaga (protocol 1729-N-23 and registred with ISRCTN15307819|| http://www.isrctn.org/ , Date submitted 12 June 2023 ISRCTN 15307819). The patients were divided into two groups based on whether the clamping technique was applied during their cesarean sections. The study assessed hemoglobin levels before and after surgery, hospitalization durations, and the prevalence of anemia at discharge as the primary outcomes. RESULTS: The patients who underwent the clamping technique demonstrated significant reductions in hemoglobin differences (0.80 g/dL) compared to the control group (1.42 g/dL). The technique also resulted in shorter hospital stays (3.02 days vs. 3.90 days) and a lower prevalence of anemia at discharge (76.2% vs. 60%). CONCLUSION: Temporary clamping of uterine arteries during cesarean sections appears to be an effective measure for preventing postpartum hemorrhaging, reducing hospital stays, and decreasing the prevalence of anemia at discharge. Further research with larger sample sizes and standardized indications is warranted to confirm the benefits and potential broader applications of this technique.

Factors associated to influenza vaccination among hospital's healthcare workers in the Autonomous Community of Madrid, Spain 2021-2022.

Influenza vaccination (IV) aims primarily to protect high-risk groups against severe influenza-associated disease and death. It is recommended in Spain for high-risk groups, including Healthcare workers (HCWs). However, vaccination uptake has been consistently below desirable levels. The objective of this study were to evaluate influenza vaccination coverage using data from the regional vaccination registry, during 2021-2022 season, among HCWs in public hospitals in Autonomous Community of Madrid (CAM) and to explore factors associated with influenza vaccination. We conducted a cross-sectional study using administrative data retrieved from the Regional Department of Health data repositories. A multilevel logistic regression model was designed to estimate Level 1 (individual) and Level 2 (contextual) variables that are associated with HCWs vaccination. The study population was HCWs from 25 public hospitals in CAM who were active during the period of the influenza 2021-2022 vaccination campaign. The global influenza vaccination coverage (IVC) was 52.1 %. All study Level 1 variables were significantly associated with vaccine uptake. Greater IVC is associated with individual characteristics: female (OR1.14; 95 %CI 1.09-1.19), older age 59-69 years old (OR1.72; 95 %CI 1.60-1.84), born in Spain, medical staff, more than one high-risk condition (OR1.24; 95 %CI 1.10-1.40; respectively) and vaccinated in two previous campaigns (OR25.64; 95 %CI 24.27-27.09). IVC was highest among HCWs celiac disease (65.5 %) followed by diabetes mellitus (65.1 %) and chronic inflammatory disease (64.3 %). The hospital where the study subject worked also showed an effect on the vaccination uptake, although Level 2 variable (hospital complexity) was not positively associated. IVC in HCWs remains suboptimal. These findings may prove useful to tailor strategies to reach specific groups. It is recommended to delve into the identification of factors associated with the HCWs workplace that may have a positive impact on IV.

Vaccination against influenza: Coverage and adherence in children under 15 years with high-risk medical conditions in the Community of Madrid.

INTRODUCTION: Vaccination against influenza is indicated in children at risk of complications or severe disease. The objective of this study was to describe the percentage of children aged less than 15 years with risk conditions vaccinated against influenza in the Community of Madrid, and to analyze the factors associated with adherence to vaccination throughout 3 vaccination campaigns. MATERIALS AND METHODS: Population-based cross-sectional observational study of children aged 6 months to 14 years with conditions that indicated influenza vaccination at the beginning of the 2018-2019 campaign. Electronic population registers were used. We described the percentage of children vaccinated in 3 consecutive campaigns, and assessed the association of adherence to vaccination with demographic and socioeconomic variables and risk conditions using bivariate and multivariate analysis. RESULTS: The vaccination coverage was 15.6% in the 2018-2019 campaign. The adherence to vaccination was 65.9%. The variables associated with greater adherence were age greater than 2 years, especially in the 6-10 years group (aOR = 1.63; 95% CI, 1.43-1.85) and presenting more than one risk condition, especially 3 or more diseases (aOR = 1.80; 95% CI, 1.00-3.26). Diabetes mellitus was the disease associated most strongly with adherence (aOR = 2.15; 95% CI, 1.74-2.65). Adherence was lower in the immigrant population (aOR = 0.43; 95% CI, 0.36-0.51). We found no association between vaccination adherence and sex or socioeconomic status. CONCLUSIONS: Vaccination coverage and adherence were suboptimal. Adherence to vaccination against influenza is associated with demographic and clinical conditions. Strategies need to be established to increase vaccination in children, with greater involvement of professionals and education of parents.

Met and Unmet Needs in an Inpatient Psychiatry Setting in Spain.

PURPOSE: Patients with severe mental disorder have health and social needs that require care. The aim of the study was to determine the main areas of perceived needs among inpatients with severe mental disorders and to identify risk factors of the group of patients with the greatest unmet needs. PATIENTS AND METHODS: A total of 150 patients with severe mental illness were assessed during admission prior to discharge from the hospital. Camberwell Assessment of Needs was used as evaluation measure, in addition to clinical status (The Brief Psychiatric Rating Scale), social functioning (Personal and Social Performance) and sociodemographic variables. A descriptive and a multivariate logistic regression analysis were used to analyse variables related to the group of patients with the highest number of unmet needs (≥3). RESULTS: Mean number of needs was 7.93, being 4.61 the mean number of needs met and 3.32 the needs unmet. The highest proportion of unmet needs were intimate relationships (44.0%), company (40.7%) and daytime activities (38.7%). A relationship was also found between the presence of three or more unmet needs and the following variables: Brief Psychiatric Rating Scale score (p=0.004), Personal and Social Performance score (p = 0.013), marital status (p=0.018), employment status (p=0.009) and voluntary admission (p=0.032). The multivariate model explained 29.5% of the variance (Nagelkerke's R2: 0.295). CONCLUSION: Treatments aimed at improving social relationships and daytime activities could be a good option for inpatients with many unmet needs.
