There is very little evidence of the similarity of the mechanics of maternal and bottle feeding. We assessed the mechanics of sucking in exclusive breastfeeding, exclusive bottle feeding, and mixed feeding. The hypothesis established was that physiological pattern for suckling movements differ depending on the type of feeding. According to this hypothesis, babies with breastfeeding have suckling movements at the breast that are different from the movements of suckling a teat of babies fed with bottle. Children with mixed feeding mix both types of suckling movements.

The diagnosis and treatment of patients with chronic obstructive pulmonary disease (COPD) in Spain continues to present challenges, and problems are exacerbated when there is a lack of coordinated follow-up between levels of care. This paper sets out the protocol for assessing the impact of an integrated management model for the care of patients with COPD. The new model will be evaluated in terms of 1) improvement in the rational utilization of health-care services and 2) benefits reflected in improved health status and quality of life for patients.

Early pulmonary rehabilitation (PR), started during hospitalization or within the first month after discharge, has been shown to reduce exacerbations and improve health-related-quality of life (HRQoL) and exercise capacity. However, no randomized clinical trials (RCT) have compared the efficacy of PR started during hospitalization (DHPR) to PR initiated one month post-hospitalization (PHPR). We conducted an RCT to compare DHPR to PHPR in severe patients with COPD readmitted for exacerbations in a tertiary hospital setting. Patients were randomized to receive three months of DHPR or PHPR. Outcomes were assessed at completion of the PR programme and at months 3 and 9. A total of 53 patients (26 DHPR and 27 PHPR) were included. There were no between-group differences in the number of exacerbations (mean, 3.62 vs. 3.04 in the DHPR and PHPR groups, respectively; p = 0.403). Dyspnea in activities of daily living, exercise capacity, and all HRQoL parameters improved in the PHPR group. In the DHPR group, improvement was observed only for some HRQoL parameters. All gains in both groups were lost during follow-up. More adverse events were observed in the DHPR group (20 vs 5, p = 0.023), although none of these were clinically significant. In this sample of patients with severe COPD readmitted to the hospital for exacerbations, both approaches to PR were safe, but PHPR yielded better outcomes overall. These findings suggest that, PR should be initiated in patients with severe COPD only after hospital discharge when the patients’ clinical condition has stabilized.

Purpose: The aim of this study was to describe the anterior cruciate ligament (ACL) injury incidence differences depending on sex and age‐related categories in a large cohort of soccer players over six consecutive seasons. Methods: This study was designed as a retrospective descriptive epidemiological study. All soccer players in a specific geographical area who sustained an ACL injury across six consecutive seasons were included in this analysis. ACL injury incidence was calculated by sex and age‐related category as a percentage of all registered soccer players in the region. Additionally, soccer participation evolution, ACL injury incidence evolution, and monthly ACL injury distribution were studied. Group, seasonal, and monthly differences were analysed using chi‐square tests. Results: Between the 2016–2017 and the 2021–2022 seasons, 3381 ACL injuries were registered from a total of 782,856 player‐seasons. ACL injury incidence was 0.43%. Female soccer players showed 2.79 times higher injury incidence than male players, with overall rates of 1.06% in females and 0.38% in males ( p < 0.001). However, female players only showed higher ACL injury incidence than males in age groups older than 14 years. ACL injury incidence increased over the six seasons studied only in the male group. October and January were the months with the highest number of ACL injuries, with no significant differences in monthly distribution between sexes. Conclusions: Female soccer players showed higher ACL injury incidence than males, particularly in age groups older than 14 years. October and January were identified as the months with the highest injury incidences regardless of sex. Additionally, a rising injury incidence was observed in male players, a trend not seen in females. Level of Evidence: Level III, retrospective comparative study.

Background: Indications for the revascularization treatment of peripheral arterial disease (PAD) generate much discussion, and practice varies significantly among hospitals. This study looked at patients with PAD admitted to all hospitals of the Catalan Health Service and analyzed patterns of revascularization techniques with subsequent amputation procedures. Methods: We used the clinical-administrative registry of admissions of all patients in the hospitals of Catalonia, north-east Spain, between 2009 and 2014. We analyzed the clinical course of patients admitted with PAD throughout their successive hospital admissions. Variability between hospitals was described for the revascularization techniques and amputations performed. Endovascular outcomes were compared with those from open surgery. Results: Annually, there were 9,828 admissions with PAD and 631 major amputations. Eight hospitals accounted for 52% of all admissions, and endovascular techniques occurred predominantly in high-tech, high-resolution or reference hospitals. The ratio of admissions involving endovascular techniques/open surgery varied from 0.02 to 3.73 according to the hospital, and had a correlation of -0.175 (P=0.447) with the percentage of performed major amputations and of 0.122 (P=0.598) ratio of minor / major amputations. At the end of the 6 studied years, endovascular revascularization resulted in lower patency and more minor amputations than open surgery, but had the same percentage of major amputations (10.3% vs. 10.7%, P=0.526) and lower in-hospital mortality (7.1% vs. 9.5%, P<0.0001). Conclusions: Interventions of PAD are centralized in complex hospitals and have an important variability depending on the treating hospital. Hospital variability in revascularization techniques seems to have no impact on leg salvage. Endovascular and surgical revascularization would result in similar percentages of major amputations.
