We compared the effects of two waste-based culture media (M1 and M2) on the technological properties of (L90) for its application as a secondary culture in Cremoso cheese. The following parameters were studied at different ripening times: pH (7, 20, and 40 d), microbiological counts, carbohydrates and organic acids (7 and 40 d), moisture, fat, protein and volatile compounds (40 d). The viability and the metabolic performance of the strain in cheeses were also verified along ripening.

Tidal marshes are coastal systems that provide valuable ecosystem services, highlighting coastal protection and carbon burial. For centuries, these dynamic ecosystems have kept pace with sea level rise through organic and mineral matter accumulation. In the current situation of accelerated sea-level rise and changes in suspended sediment concentrations, the evolution of these systems has gained special attention across scientific fields.

Article Synopsis
  • A study was conducted to evaluate the health-related quality of life (HRQOL) of very preterm children (born before 32 weeks) compared to their full-term siblings and the general population, involving 442 preterm children and 145 of their siblings.
  • It found that very preterm children showed similar HRQOL scores to full-term siblings and peers, suggesting preterm birth does not significantly impair HRQOL.
  • Chronic health conditions, age, and respiratory issues were identified as significant factors affecting HRQOL in preterm children, indicating potential areas for improvement.

Introduction: Understanding the relationships between taxonomic, functional, and phylogenetic diversity and endemism across environmental gradients is essential for elucidating the eco-evolutionary mechanisms that shape local plant communities.

Methods: A database was compiled from field surveys, national herbarium records, and virtual records of perennial plant specimens collected in the aridity gradient of northern Chile, between 18 and 32°S. A large-scale dated phylogeny of available perennial plants was used, and 11 functional traits were selected to construct a dendrogram using the Unweighted Pair-Group Method with Arithmetic Mean (UPGMA) method for the species present in our database.

Clinical trials (CTs) are essential for medical advancements but face significant challenges, particularly in professional training and role clarity. Principal investigators, clinical research coordinators (CRCs), nurses, clinical trial pharmacists, and monitors are key players. Each faces unique challenges, such as maintaining protocol compliance, managing investigational products, and ensuring data integrity.

Objective: The existence of catch-up lung function growth and its predictors is uncertain. We aimed to identify lung function trajectories and their predictors in a population-based birth cohort.

Methods: We applied group-based trajectory modelling to z-scores of forced expiratory volume in 1 second (zFEV) and z-scores of forced vital capacity (zFVC) from 1151 children assessed at around 4, 7, 9, 10, 11, 14 and 18 years.

Unlabelled: Understanding health-related quality of life (HRQOL) in children and adolescents, during a pandemic and afterwards, aids in understanding how circumstances in their lives impact their well-being. We aimed to identify determinants of HRQOL from a broad range of biological, psychological, and social factors in a large longitudinal population-based sample. Data was taken from a longitudinal sample (n = 1843) of children and adolescents enrolled in the prospective school-based cohort study Ciao Corona in Switzerland.

Plant-pollinator interactions are ecologically and economically important, and, as a result, their prediction is a crucial theoretical and applied goal for ecologists. Although various analytical methods are available, we still have a limited ability to predict plant-pollinator interactions. The predictive ability of different plant-pollinator interaction models depends on the specific definitions used to conceptualize and quantify species attributes (e.

Introduction: Patients with chronic obstructive pulmonary disease (COPD) accumulate low levels of physical activity. How environmental factors affect their physical activity in the short-term is uncertain.

Aim: to assess the short-term effects of air pollution and weather on physical activity levels in COPD patients.

Cantabria Cohort stems from a research and action initiative lead by researchers from Valdecilla Research Institute (IDIVAL), Marqués de Valdecilla University Hospital and University of Cantabria, supported by the regional Goverment. Its aim is to identify and follow up a cohort that would provide information to improve the understanding of the etiology and prognosis of different acute and chronic diseases. The Cantabria Cohort will recruit between 40,000-50,000 residents aged 40-69 years at baseline, representing 10-20% of the target population.

We investigated changes in adherence to physical activity (PA) and screen time (ST) recommendations of children and adolescents throughout the pandemic, and their association with health-related quality of life (HRQOL). 1,769 primary (PS, grades 1-6) and secondary (SS, 7-9) school children from Ciao Corona, a school-based cohort study in Zurich, Switzerland, with five questionnaires 2020-2022. HRQOL was assessed using the KINDL questionnaire.

Article Synopsis
  • Soils are key carbon reservoirs, storing more carbon than other land ecosystems, but the mechanisms behind soil organic carbon (SOC) formation and persistence are still unclear, complicating predictions about their behavior in a changing climate.
  • Microorganisms are critical in influencing SOC through various processes, and microbial carbon use efficiency (CUE) serves as a key indicator of how these processes balance, impacting SOC storage.
  • Research suggests that CUE is significantly more important than other factors like carbon input or decomposition in determining SOC levels globally, and a better understanding of CUE and its environmental interactions could enhance predictions of SOC responses to climate change.

Article Synopsis
  • - The study investigates the prevalence and severity of respiratory symptoms in children born very preterm (under 32 weeks) and their effects on parents' health-related quality of life (HRQoL) and family functioning, focusing on children recruited in Zurich, Switzerland, from 2006 to 2019.
  • - Over 600 very preterm children (including those with bronchopulmonary dysplasia) and 180 control children completed an online survey assessing respiratory health and family impact, revealing that very preterm children reported significantly more respiratory issues than controls, particularly those aged 6-18 years.
  • - Results indicate that parents of children with respiratory symptoms experienced lower HRQoL scores, highlighting that respiratory issues in very preterm

Background: We previously reported an association of high fat mass levels from age 9 to 15 years with lower forced expiratory flow in 1 s (FEV )/forced vital capacity (FVC) ratio (i.e., increased risk of airflow limitation) at 15 years.

Article Synopsis
  • The study analyzed changes in physical activity, screen time, and sleep duration among Swiss children during the early waves of the COVID-19 pandemic, involving 2,534 participants aged 5-16.
  • Results indicated a decline in adherence to recommended lifestyle behaviors from pre-pandemic to the first wave, with a slight recovery during the second wave.
  • Children who met all three lifestyle recommendations (physical activity, screen time, and sleep) during the second wave reported better health and higher life satisfaction compared to those who did not meet any recommendations.
