Prevalence of contrast intravasation in HyCoSy/HyFoSy. Results of a multicenter study and systematic review of the literature with meta-analysis.

Objective: To determine the frequency of uterine contrast agent intravasation during HyCoSy/HyFoSy for assessing tubal patency in infertile women.

Methods: Prospective observational multicenter study performed in nine European university hospitals, comprising a series of non-consecutive women who underwent HyFoSy (ExEm foam) for tubal patency assessment in the context of infertility between May 2016 and December 2022.

Pregnancy outcomes with the pregestational use of Minimed 780G compared to Minimed 640G: findings from a multicenter cohort study.

Aim: To compare glycemic control and maternal-fetal outcomes of women with type 1 diabetes (T1D) using Minimed™ 780G (MM780G) with those women using Minimed™ 640G (MM640G) since before pregnancy.

Methods: Multicenter prospective cohort study of pregnant women with T1D in Spain. We evaluated HbA1c, time spent within (TIRp), below (TBRp) and above (TARp) the pregnancy-specific glucose range 3.

Ecological study to estimate the prevalence of patients with acid sphingomyelinase deficiency in Spain. PREVASMD study.

Background And Objective: Prevalence studies of acid sphingomyelinase deficiency (ASMD) are scarce and different in Spain. The objective of the present study was to determine the estimated prevalence of patients diagnosed with ASMD (types A/B and B) in Spain.

Material And Methods: PREVASMD was a descriptive, multicenter, and ecological study involving 21 physicians from different specialties (mainly Internal Medicine, Paediatrics and Hematology), of different autonomous communities, with experience in ASMD management.

Oncological safety of fertility preservation treatment in ovarian cancer: A Spanish multicenter study.

Objective: To assess the safety of fertility-sparing treatments for early-stage ovarian cancer in women younger than 40 years old.

Methods: We performed a retrospective multicenter study including women aged 18-40 years diagnosed with early-stage (FIGO I-II) ovarian cancer in 55 Spanish hospitals, from January 2010 to December 2019. Benign and borderline tumors were excluded, as well as advanced stages (FIGO III-IV).

Pediatric kidney transplantation in Europe, a clinical snapshot pilot.

Background: Pediatric kidney transplantations are rarely performed, and there is limited knowledge about the diversity in current clinical practices across Europe. This study aims to explore the utility of clinical snapshot studies in identifying these disparities, establishing a foundation for future snapshot studies and standardization efforts.

Methods: A pilot clinical snapshot study was conducted, with invitations extended to all 109 pediatric kidney transplant centres in Europe.

Documenting adaptations to an evidence-based intervention in 58 resource-variable pediatric oncology hospitals across implementation phases.

Background: Adaptation of evidence-based interventions (EBIs) often occurs when implemented in new local contexts and settings. It is unclear, however, during which phase of implementation adaptations are most frequently made and how these changes may impact the fidelity, effectiveness, and sustainability of the EBI. Pediatric Early Warning Systems (PEWS) are EBIs for early identification of deterioration in hospitalized children with cancer.

Torque teno virus: a potential marker of immune reconstitution in youths with vertically acquired HIV.

Torque teno virus (TTV) viral load (VL), a component of the human virome, increases during immune suppression or dysregulation. This study aimed to explore TTV VL in youths living with vertically acquired HIV (YWVH) and its potential as an immunovirological marker. We performed an observational, retrospective study involving YWVH under antiretroviral treatment (ART) from the Spanish Cohort of HIV-infected children, adolescents, and vertically HIV-infected patients transferred to Adult Units (CoRISpe-FARO), compared to HIV-negative healthy donors (HD).

Impact of the COVID-19 Pandemic on Pediatric Bacterial Community-Acquired Pneumonia: A Multicenter Retrospective Study in Madrid (Spain).

This study conducted in Madrid (Spain) between 2018 and 2023 shows a significant decrease in the pediatric bacterial community-acquired pneumonia cases during the COVID-19 pandemic, followed by a notable postpandemic increase surpassing prepandemic incidence. Streptococcus pneumoniae remains predominant, with an increasing prevalence of serotype 3, while Streptococcus pyogenes was the second most common pathogen.

National survey on clinical practice in obstetric analgesia in Spain.

Introduction: A national survey was conducted among maternity hospitals nationwide to understand the variability in clinical practice for obstetric analgesia and to reach a consensus on optimal care in the future in Spain.

Materials And Methods: Spanish experts in obstetric anesthesiology designed a survey on the practice of obstetric analgesia during childbirth, following a Delphi process. The survey was sent to 195 Spanish maternity hospitals between April and September 2022 using Google Forms.

Impact of COVID-19 infection on lung function and nutritional status amongst individuals with cystic fibrosis: A global cohort study.

Background: Factors associated with severe COVID-19 infection have been identified; however, the impact of infection on longer-term outcomes is unclear. The objective of this study was to examine the impact of COVID-19 infection on the trajectory of lung function and nutritional status in people with cystic fibrosis (pwCF).

Methods: This is a retrospective global cohort study of pwCF who had confirmed COVID-19 infection diagnosed between January 1, 2020 and December 31, 2021.

Reproductive and pregnancy control in Wilson disease patients in Spain.

Background And Aim: Recommendations on pregnancy, lactation, and contraception in women with Wilson disease are briefly stated in international guidelines but are not entirely homogeneous. Data regarding the management of these special events among patients with Wilson disease in Spain are lacking. We used the Wilson Registry platform of the Spanish Association for the Study of the Liver to question patients on their reproductive and gestational lives.

Clinical practice guidelines for the treatment of Ewing sarcoma (Spanish Sarcoma Research Group-GEIS).

Ewing sarcoma is a small round-cell sarcoma characterized by gene fusion involving EWSR1 (or another TET family protein like FUS) and an ETS family transcription factor. The estimated incidence of this rare bone tumor, which occurs most frequently in adolescents and young adults, is 0.3 per 100,000/year.

Identification of copy-number variants in patients with overgrowth disorders.

Overgrowth syndromes (OGS) comprise a heterogeneous group of disorders whose main characteristic is that the weight, height or the head circumference are above the 97th centile or 2-3 standard deviations above the mean for age, gender, and ethnic group. Several copy-number variants (CNVs) have been associated with the development of OGS, such as the 5q35 microdeletion or the duplication of the 15q26.1-qter, among many others.

Real Implication of Fertility-Sparing Surgery for Ovarian Cancer: Reproductive Outcomes.

Background: to prove the effectivity of fertility-sparing procedures in early-stage ovarian cancer by assessing pregnancy rates and obstetrical outcomes.

Methods: we performed a retrospective multicenter study among 55 Spanish hospitals, collecting patients from 18 to 40 years old with diagnosis of early-stage ovarian cancer, epithelial (EOC) or non-epithelial (non-EOC), from January 2010 to December 2019. Data on the use of assisted reproductive techniques, pregnancy attempts and obstetrical outcomes were collected.

Increased Severity of Mycoplasma pneumoniae Infections in Spanish Children.

Background: Since the end of 2023, an elevated incidence and severity of Mycoplasma pneumoniae infections among children in Asia has been noted. Subsequently, this trend was observed in several European countries although limited data are currently available. We conducted a national study to delineate the ongoing M.
