Impact of an Intervention Aimed at Improving Sleep Quality in Hospitalized Children.

BACKGROUND: Hospitalized children need adequate sleep to favor early recovery. METHODS: To study the sleep pattern of children admitted to a pediatric inpatient unit, a cross-sectional study was carried out at a reference hospital in northern Spain. The main study variables were medical specialty of admission, sleep-inducing treatment, hours of sleep at home and during admission, number of nocturnal awakenings, and reasons for awakening. Differences in the hours of sleep and nighttime awakenings between the initial period and at six months were calculated using the Student's t-test. RESULTS: We included 100 baseline patients and 100 post-intervention patients. Up to 4% of the baseline sample and 3% of the six-month sample had been prescribed a sleep-promoting drug. Regarding awakenings, 79% of the children in the baseline sample suffered awakenings, with a mean of 1.98 awakenings (range 1-13). At six months, the percentage of children who experienced awakenings decreased by 17%, with a mean of 1.34 (range 1-5). In the baseline sample, 48% were caused by nursing care, decreasing to 34% after the intervention. CONCLUSIONS: An educational intervention with the implementation of targeted evidence-based practices is a useful measure for improving the sleep pattern by decreasing the number of awakenings.

Promoting sleep and rest in hospitalized children: a best practice implementation project.

OBJECTIVE: The objective of this project was to implement scientific evidence to promote sleep and rest in pediatric patients during hospitalization. INTRODUCTION: Hospitals are not conducive to quality sleep, as external factors such as light, noise, and interruptions from health care staff can disturb patients. Being hospitalized has a detrimental impact on children's sleep because it reduces how much sleep they get and the quality of that sleep. It has been reported that up to 20% to 30% of hospitalized children experience sleep problems. METHODS: This project was conducted at the Marqués de Valdecilla University Hospital in Cantabria, northern Spain. The project used the JBI Evidence Implementation Framework, which is grounded in an audit, feedback, and re-audit process, together with a structured approach to identifying and managing barriers to change. The study subjects were 100 children aged 2 to 16 years, who were admitted to the hospital's pediatric unit from November to December 2021, and 27 multi-disciplinary health care staff. RESULTS: Implementing the evidence-based strategies improved our care practices, with the follow-up audit results showing a marked improvement in compliance. Thus, training health care staff on pediatric sleep increased from 4% to 80%; using a multi-faceted approach to sleep promotion increased from 21% to 87%; and promoting relaxation techniques to promote sleep increased from 0% to 80%. CONCLUSIONS: The project met its objectives. Areas for improving children's sleep and rest during hospitalization were identified. To avoid resistance to change, it was necessary to involve the entire team and maintain training. We recommend follow-up audits once a year, to ensure the sustainability of the project.

Development of SARS-CoV-2 specific IgG and IgA antibodies in serum and milk with different SARS-COV-2 vaccines in lactating women.

BACKGROUND: Our main objective was to determine the evolution of IgG and IgA antibodies directed against SARS-CoV-2 protein S in the blood of lactating women and in breast milk. METHODS: A cohort of 110 uninfected and vaccinated breastfeeding women was followed-up for 6 months at the Marqués de Valdecilla University Hospital, Spain, in 2020. An additional group of 23 breastfeeding mothers who had no previously documented infection and had not been vaccinated against SARS-CoV-2 were included as a control group. The antibodies in blood and breast milk and their evolution at 6 months post-vaccination were analysed. RESULTS: One hundred ten breastfeeding mothers were included; 70 women (63.6%) were vaccinated with two doses of BNT162b2, 20 women (18.2%) received two doses of mRNA-1273, and 20 women (18.2%) received a single dose of ChAdOx1-S. No evidence of differences between concentrations of antibodies was found according to the type of vaccine, with the exception of serum IgA antibodies, which was higher in women vaccinated with mRNA-1273: mean [95%CI]: 0.05 AU/mL [0.03,0.06] with mRNA-1273, 0.02 AU/mL [0.01,0.03] with BNT162b2 and 0.01 AU/mL [0.00,0.03] with ChAdOx1-S, ANOVA p value = 0.03. The lack of difference between vaccines was also found when anti-S1 specific IgG in serum and breast milk were measured. CONCLUSIONS: In lactating women vaccinated against COVID-19, anti-SARS-CoV-2 antibodies can be detected in both serum and breastmilk 6 months after receiving the second dose, although their concentrations decreased when compared with concentrations reached immediately after vaccination.

Declared Reasons for Cessation of Breastfeeding during the First Year of Life: An Analysis Based on a Cohort Study in Northern Spain.

BACKGROUND: Breastfeeding is the gold standard of infant feeding due to the many advantages it offers to both the child and the mother. OBJECTIVE: To identity the main reasons for cessation of breastfeeding reported by mothers during the first year of life. DESIGN: A prospective cohort study was conducted, recruiting 970 infants from a university hospital in Spain. The main maternal variables studied were maternal age, parity, educational level, work occupation, smoking habit, weeks of gestation at birth, birth weight, feeding type, and duration of breastfeeding. All participants were followed for one year to determinate the duration of breastfeeding and to gather reasons for abandoning breastfeeding. RESULTS: At six months, the percentage of breastfeeding experienced a decline of 50%, and only 24.5% of these mothers maintained breastfeeding. Up to 15.8% of the mothers decided to give up exclusive breastfeeding by their own choice, whereas 15.4% did so because they suspected low milk production. Work-related causes represent the third reason of abandonment. CONCLUSIONS: Our results highlight the need to improve the health policies for the promotion, protection, and support for the initiation and maintenance of breastfeeding. In particular, our results highlight the importance of researching women's low milk production and work-related factors, with particular emphasis on improving conciliation measures.

Induction of SARS-CoV-2-Specific IgG and IgA in Serum and Milk with Different SARS-CoV-2 Vaccines in Breastfeeding Women: A Cross-Sectional Study in Northern Spain.

Breastfeeding mothers were excluded from the clinical trials conducted for vaccines against SARS-CoV-2. Since the start of the vaccination, some doubts have arisen regarding its compatibility with breastfeeding. The aim of this study was to analyse the presence of anti-SARS-CoV-2 antibodies in breast milk and serum (IgG and IgA) of vaccinated breastfeeding women. The main variables of the observational study were: adverse related events after vaccination and determination of the presence of IgG and IgA isotypes antibodies in serum and in breast milk of vaccinated women against the SARS-CoV-2 antigens. Results: 110 breastfeeding mothers were included; 70 women (63.6%) were vaccinated with two doses of BNT162b2, 20 women (18.2%) with two doses of mRNA-1273, and 20 women (18.2%) with a single dose of ChAdOx1-S. Regarding adverse reactions and vaccine safety, 38 women had no adverse reactions; 20 (18.2%) had general malaise or adenopathies; 10 (9.1%) had a headache; and 7 (6.4%) had fever. When analysing IgG antibodies, significantly higher levels of antibodies were found in serum and breast milk from mothers vaccinated with BNT162b2 or mRNA-1273 vs. ChAdOx1-S (p < 0.001 and p = 0.001, respectively). Analysing IgA antibodies, significant differences were found when comparing mean values in serum from mothers vaccinated with BNT162b2 or mRNA-1273 vs. ChAdOx1-S (0.12, 0.16, and 0.02, respectively; p < 0.001) and breast milk of mothers vaccinated when comparing BNT16b2 vs. ChAdOx1-S. All vaccinated breastfeeding mothers had serum anti-S1 IgG antibodies in response to vaccination against SARS-CoV-2, regardless of the commercial vaccine administered. Conclusions: the anti-SARS-CoV-2 vaccines were well tolerated by the mothers and the breastfed infant. In addition, breastfeeding mothers offer their infants IgA and IgG isotype antibodies directed against SARS-CoV-2 protein S in breast milk.

High prevalence of cryofibrinogenemia in patients with chilblains during the COVID-19 outbreak.

BACKGROUND: Many cutaneous manifestations have been described in possible association with the COVID-19 pandemic, including acral lesions resembling chilblains. The underlying pathomechanisms of COVID-19 chilblains are not fully understood. The aim of this study was to describe the clinical, pathological, and laboratory findings of a series of patients who developed chilblains during the COVID-19 outbreak and to investigate the possible factors that could be involved in the pathogenesis of these lesions. METHODS: We conducted a prospective cohort study that included 54 patients who presented with chilblains during the highest peak in the incidence of COVID-19 in Cantabria (northern Spain). Skin biopsies were performed on 10 of these patients who presented with recent lesions. Laboratory investigations, including immunological analysis, serological studies, and the assessment of cryoproteins, were also performed. RESULTS: Most patients presented erythematous plaques located on the toes and/or purpuric macules located on the feet. Histopathological findings were compatible with those of idiopathic chilblains. Immunohistochemical evaluation showed C3d and C4d deposits in the vessel walls in seven cases. The autoimmunity panel was negative in most of our series. Cryoprotein testing showed positive cryofibrinogen in two-thirds (66.7%) of the patients assessed. On follow-up, most patients presented almost complete resolution, although six patients required prednisone and antiaggregant drug treatment. CONCLUSIONS: This study shows, for the first time to our knowledge, a high prevalence of cryofibrinogenemia in patients with chilblains during the COVID-19 pandemic. Cryofibrinogenemia could be implicated in the pathogenesis of chilblains related to COVID-19.

Impact of Maternal Smoking on the Onset of Breastfeeding versus Formula Feeding: A Cross-Sectional Study.

This study sought to estimate the prevalence of maternal smoking and its association with exclusive breastfeeding vs. formula feeding. A cross-sectional study was performed on postpartum women at a public hospital in Spain, between January and August 2018. The main variables studied were their age, level of study, smoking habits, and chosen mode of infant feeding. In total, 948 postpartum women were included. Of these, 12.45% were smokers who smoked a mean of 7.23 cigarettes/day. Among the group of smokers, the probability of feeding the newborns with formula milk was multiplied by 2.32 ([95%CI 1.50-3.58] p < 0.001). When stratifying tobacco use into mild, moderate and severe, we found a statistically significant dose-response pattern. These associations and their statistical significance were maintained when adjusting by age and level of study. In conclusion, in the group of postpartum mothers who smoked, the probability of feeding the newborns with formula milk doubled. Our data highlight the need to improve health education programs in women of childbearing age, especially during pregnancy.

[Influence of demographic changes on the number of visits to hospital emergency departments: 13 years experience]. / Influencia de los cambios demográficos en la frecuentación de urgencias hospitalarias: 13 años de experiencia.

OBJECTIVE: The aim of the present study is to describe the trend in volume and age-specific rates in visits to the Paediatric Emergency Department of a university teaching hospital in Cantabria (Spain) from January 2001 to December 2013, and evaluate the influence of population growth on Emergency Department use. MATERIAL AND METHODS: A retrospective study was conducted in which an analysis was made on all Emergency Department visits over a 13 year period. Simple and polynomial linear regressions were used to assess the relationship between population size and Emergency Department attendance rates across 2 age groups (0-2 and 3-14 years). RESULTS: From 2001 to 2013, attendance in the Emergency Department increased by 14.1%, whereas the paediatric population rose by 26.3%. Rates of presentation per head of population were greatest among those aged<3 years: 1.48 (95% CI 1.40-1.56) vs. 0.46 (95% CI 0.44-0.48) for the older age group (P<.01). A significant regression equation was found (F[1, 11]=11.2, P<.05) with an R2=0.50, showing that population growth produces a continuous rise in the Emergency Department visits for those aged<3 years. However, ED presentations of patients aged 3-14 years fit a quadratic regression model (R2=0.48, F[2, 10]=4.6, P<.05) so increases in population increase ED presentations until an inflection point, after which increases in population will decrease ED visits. CONCLUSIONS: Those aged 0-2 years presented a steady increase in ED visits related to population growth, whereas children aged 3-14 years experienced a "saturation of the demand" and a reduction in ED presentations.

Influencia de los cambios demográficos en la frecuentación de urgencias hospitalarias: 13 años de experiencia / Influence of demographic changes on the number of visits to hospital emergency departments: 13 years experience

Objetivo: Este estudio evalúa la influencia del crecimiento de la población en la utilización del Servicio de Urgencias Pediátricas de un hospital universitario de Cantabria (España) entre enero de 2001 y diciembre de 2013. Material y métodos: Se realizó un estudio retrospectivo de todas las urgencias ocurridas durante 13 años. Se emplean modelos de regresión lineal simple y polinómica para analizar la relación entre la población y la frecuentación en 2 grupos de edad (0-2 y 3-14 años). Resultados: De 2001 a 2013, las urgencias aumentaron un 14,1% y la población pediátrica un 26,3%. Las tasas de presentación por persona fueron mayores en los menores de 3 años, 1,48 (IC 95% 1,40 a 1,56) frente a 0,46 (IC 95% 0,44 a 0,48) (p < 0,01). El modelo de regresión lineal simple muestra que el crecimiento de la población produce un aumento continuo de las urgencias en los menores de 3 años (R2 = 0,50, F(1, 11) = 11,2, p < 0,05). En pacientes de 3 a 14 años la frecuentación se ajusta a un modelo de regresión cuadrática (R2 = 0,48, F(2, 10) = 4.6, p < 05) y el incremento de la población aumenta las urgencias hasta alcanzar un punto de inflexión a partir del cual disminuyen. Conclusiones: El grupo de edad de 0 a 2 años presentó un aumento constante en las urgencias relacionado con el crecimiento de la población, mientras que el grupo de 3 a 14 años experimentó una «saturación de la demanda» y una reducción de las visitas
