RESUMEN
AIM: This retrospective cohort study aimed to compare the risk of serious infections in patients with rheumatoid arthritis (RA) treated with tumor necrosis factor-α inhibitors (TNFαi) and interleukin-6 inhibitors (IL-6i), with no prior use of biological disease-modifying antirheumatic drugs (bDMARDs). METHODS: We employed the nationwide insurance claims database encompassing the years 2005 to 2018 in Japan. The inclusion criteria specified patients who were prescribed any type of bDMARDs, including TNFαi and IL-6i. The following exclusion criteria were applied: missing prescription dates, RA not diagnosed, below 16 years of age, bDMARDs prescribed within 6 months of registration, RA diagnosed post-bDMARDs prescription, and incidence of serious infections within 2 weeks before bDMARDs therapy. We applied stabilized inverse probability weights and utilized a Cox regression model to estimate the risk of serious infections associated with TNFαi and IL-6i. RESULTS: The cohort of 2493 patients with RA was categorized into a TNFαi group and an IL-6i group of 2018 and 475 participants, respectively. The median follow-up duration (interquartile range) was 347 (147-820) days in the TNFαi group and 369 (149-838) days in the IL-6i group. In the inverse probability-weighted cohort, the incidence rates (95% confidence interval) of serious infections were 2.13 (1.65-2.71) and 3.25 (2.15-4.69) per 100 person-years for the TNFαi and IL-6i groups, respectively. The hazard ratio (95% confidence interval) comparing the TNFαi group to the IL-6i group was 0.66 (0.36-1.20, p = 0.168). DISCUSSION: The results underscore the lack of evidence to preferentially favor either TNFαi or IL-6i as later-line therapy in the management of bDMARDs-naive RA to mitigate the risk of serious infections.

PURPOSES: This study aimed to retrospectively assess the response to a newly developed compression brace for improving the deformity of the secondary pectus carinatum in infants and toddlers undergoing cardiac surgery with midline sternotomy. Factors affecting the response to the brace were identified. METHODS: Fifty-one children were enrolled. Severity was expressed as the protrusion angle of the sternum obtained from chest X-ray. The patients were divided into two groups by positive or negative binary residuals of the relationship between the angle at the beginning and its percentage change after wearing the brace. Logistic regression analysis was used to identify the influencing factors. RESULTS: Thirty patients (58.8%) showed zero and positive residuals to the relationship (good responders, Group G), whereas 21 patients showed negative residuals (poor responders, Group P). Male sex, severe cardiac anomaly, complex surgical procedure, multiple sternotomy, total duration, and self-discontinuation were associated with poor response to the brace by univariate analysis. The first three factors remained with high odds ratio for poor response by multivariate analysis. No adverse events occurred with the brace. CONCLUSION: Our newly developed compression brace contributed, at least in part, to improve the deformity of the secondary pectus carinatum. Further studies are required to clarify the therapeutic efficacy of anterior chest compression for secondary pectus carinatum.
RESUMEN
A 40-year-old man was incidentally found to have right-sided pelvic arteriovenous malformation (AVM) with an aneurysmal dominant outflow vein (DOV). The AVM had two main feeding arteries forming a cluster of fine vessels shunt to the DOV. As transvenous approach was impossible due to anatomical difficulty, transarterial ethanol embolization was performed under simultaneous double microballoon occlusion of the two feeding arteries in combination with protective coil embolization of the prostatic branches. Ethanol (13 mL) was intermittently injected from both microballoon catheters until the AV shunt was completely occluded. At 1-year follow-up, contrast-enhanced CT revealed shrinkage of the thrombosed DOV without any symptom. Our case demonstrated the usefulness of simultaneous double microballoon-occluded ethanol embolization for treating a localized pelvic AVM with a few feeding arteries.
RESUMEN
BACKGROUND: In 2018, diagnostic criteria were introduced for IgG4-related periaortitis/periarteritis and retroperitoneal fibrosis (PA/RPF). This study assessed the existing criteria and formulated an improved version.MethodsâandâResults: Between August 2022 and January 2023, we retrospectively analyzed 110 Japanese patients diagnosed with IgG4-related disease (IgG4-RD) involving cardiovascular and/or retroperitoneal manifestations, along with 73 non-IgG4-RD patients ("mimickers") identified by experts. Patients were stratified into derivation (n=88) and validation (n=95) groups. Classification as IgG4-RD or non-IgG4-RD was based on the 2018 diagnostic criteria and various revised versions. Sensitivity and specificity were calculated using experts' diagnosis as the gold standard for the diagnosis of true IgG4-RD and mimickers. In the derivation group, the 2018 criteria showed 58.5% sensitivity and 100% specificity. The revised version, incorporating "radiologic findings of pericarditis", "eosinophilic infiltration or lymphoid follicles", and "probable diagnosis of extra-PA/-RPF lesions", improved sensitivity to 69.8% while maintaining 100% specificity. In the validation group, the original and revised criteria had sensitivities of 68.4% and 77.2%, respectively, and specificities of 97.4% and 94.7%, respectively. CONCLUSIONS: Proposed 2023 revised IgG4-related cardiovascular/retroperitoneal disease criteria show significantly enhanced sensitivity while preserving high specificity, achieved through the inclusion of new items in radiologic, pathological, and extra-cardiovascular/retroperitoneal organ categories.
RESUMEN
We describe a technique to repair ischemic ventricular septal rupture via a left ventriculotomy. It employs a large endoventricular patch as a "lining" over the locally patched septal defect and the free wall defect which is going to be roofed with an external patch. Both defects are then closed in double layers, holding a single continuous patch. The technique enhances the advantage of the left ventriculotomy in the repair and minimizes ventriculotomy-related morbidity.
