Background: To investigate the concurrent, long-term, and future adverse events and assess the trend of adverse events in pediatric patients with patent ductus arteriosus (PDA) after transcatheter closure.

Methods: A total of 1590 patients underwent transcatheter PDA closure were enrolled, including 465 patients (median age = 22 months) in the training group and 1125 patients in the validation group. Logistic regression analysis was used to assess independent risk factors associated with concurrent adverse events after closure. The chi-square test was used to evaluate the 5-year follow-up trend.

Results: Multivariable logistic regression analysis indicated that low age, female, and high pulmonary end diameter were independent risk factors for concurrent adverse events after closure. For patients without concurrent adverse events and for those who with concurrent adverse events but return to normal, the Chi-square test showed no abnormal results at the 5-year follow-up. Furthermore, the follow-up data of the validation group were not significantly different from those of the training group.

Conclusion: The value of long-term follow-up of children may be limited for those who did not have a concurrent adverse event after closure nor for those who had a concurrent adverse event after closure but returned to normal during the 5-year follow-up period.

Impact: Follow-up monitoring of adverse events tended to be recommended in pediatric patients with PDA after transcatheter closure. However, follow-up in these pediatric patients is expensive and there is a risk of sedation for echocardiography examination frequently. ·Patients who had no concurrent adverse events after closure did not show any abnormality at 5-year follow-up. ·Most of the patients who had concurrent adverse events after closure returned to normal at 5-year follow-up. The value of long-term follow-up may be limited for the above patients after transcatheter PDA closure.

Importance: Routine preoperative blood tests and electrocardiograms before low-risk surgery do not prevent adverse events or change management but waste resources and can cause patient harm. Given this, multispecialty organizations recommend against routine testing before low-risk surgery.

Objective: To determine whether a multicomponent deimplementation strategy (the intervention) would reduce low-value preoperative testing before low-risk general surgery operations.

Background: Proprotein convertase subtilisin/kexin type 9 (PCSK9) monoclonal antibodies (mAbs) have demonstrated promising effects in lowering cardiovascular incidents among patients with acute coronary syndrome. However, their influence on early platelet reactivity after primary percutaneous coronary intervention (PPCI) remains unclear.

Objectives: This research sought to investigate the effects of entirely human anti-PCSK9 antibodies on platelet function as measured by thrombelastography and 12-month postoperative results in patients receiving PPCI and treated with ticagrelor-based dual antiplatelet therapy.

Introduction: Many interventional strategies are commonly used to treat chronic low back pain (CLBP), though few are specifically intended to target the distinct underlying pathomechanisms causing low back pain. Restorative neurostimulation has been suggested as a specific treatment for mechanical CLBP resulting from multifidus dysfunction. In this randomized controlled trial, we report outcomes from a cohort of patients with CLBP associated with multifidus dysfunction treated with restorative neurostimulation compared to those randomized to a control group receiving optimal medical management (OMM) over 1 year.

Introduction: Results from randomized controlled trials of upadacitinib, a Janus kinase (JAK) inhibitor, have led to its approval for the treatment of moderate-to-severe atopic dermatitis (AD) in patients aged ≥ 12 years. The aim of this study was to report the effectiveness and safety of upadacitinib in real-world settings over a period of 96 weeks.

Methods: This retrospective study included all patients treated with upadacitinib at our centre between April 2022 and September 2024.

Background: The purpose of this study was to compare outcomes and adverse events between three-dimensional conformal radiation therapy (3D-CRT) and intensity-modulated radiation therapy (IMRT) in patients undergoing long-course neoadjuvant radiation therapy (NA-RT) for locally advanced rectal adenocarcinoma (LARC).

Methods: We retrospectively analyzed a total of 47 consecutive patients who received NA-RT for LARC between January 2011 and September 2022. Seven and 40 patients were diagnosed with clinical stages II and III, respectively.
