Article Abstract
Aims: Periprosthetic femoral fracture (PPFF) is a major complication following hip arthroplasty. This study examined the influence of femoral component design and fixation method on the risk of reoperation for PPFF.
Methods: We analyzed data on femoral component type use for primary hip arthroplasty stems reported to the Norwegian Arthroplasty Register and the Norwegian Hip Fracture Register from 1 January 2005 to 31 December 2023. The study included 187,576 well-documented femoral components used in hemi- and total hip arthroplasties which were assessed by Cox regression. The femoral components were categorized into five groups: 1) cemented composite beam (n = 30,415), and two types of cemented polished taper-slip components; 2) double-tapered (n = 52,255); 3) triple-tapered (n = 13,894), and two types of uncemented femoral components; 4) wedged collarless (n = 38,389); and 5) wedged collared (n = 40,853). Endpoint was reoperation for PPFF (revisions and osteosyntheses).
Results: A total of 1,398 femoral components (0.7%) were reported with a reoperation due to PPFF. The risk of reoperation was significantly higher for cemented double-tapered (adjusted hazard rate ratio (aHRR) 4.0 (95% CI 3.1 to 5.2), cemented triple-tapered (aHRR 4.0 (95% CI 2.9 to 5.6)), uncemented wedged collarless (aHRR 7.3 (95% CI 5.6 to 9.5)), and uncemented wedged collared (aHRR 3.5 (95% CI 2.6 to 4.6)) components compared to cemented composite beam components. Cemented triple-tapered prostheses exhibited a similar risk of reoperation (aHRR 1.0 (95% CI 0.8 to 1.3)) to cemented double-tapered components. Uncemented wedged collarless prostheses were associated with a higher risk of PPFF (aHRR 2.1 (95% CI 1.8 to 2.5)) compared to uncemented wedged collared designs.
Conclusion: To minimize the risk of PPFF, cemented composite-beam femoral components should be the surgeon's preferred choice. If cementing is not an option, uncemented wedged collared components are the best alternative. Opting for a cemented triple-tapered design does not improve outcomes compared to double-tapered component.

How many doses and what type of antibiotic should be used as systemic antibiotic prophylaxis in primary hip and knee arthroplasty? A register-based study on 301,204 primary total and hemi- hip and total knee arthroplasties in Norway 2005-2023.

Background And Purpose: Guidelines for systemic antibiotic prophylaxis (SAP) in arthroplasty surgery vary worldwide from repeated doses to only 1 preoperatively. We aimed to investigate, primarily whether 4 doses reduced the risk of PJI compared with 1 to 3 doses, and secondarily if there was a difference between types of antibiotics.
Methods: Patients reported to the Norwegian Arthroplasty Register and the Norwegian Hip Fracture Register with primary total knee (TKA), total (THA) or hemi- (HA) hip arthroplasty between 2005 and 2023 were included.
Predictive value and mediating effect analysis of the AHR-ARNT-CYP1A1 axis for missed abortion related to polycyclic aromatic hydrocarbons exposure.

This study aimed to determine the predictive value of aryl hydrocarbon receptor (AHR) signaling pathway genes, and to detect the mediating effect of AHR that may mediate the influence of polycyclic aromatic hydrocarbons (PAHs) on missed abortion. The present study was conducted using a 1:2 matched case-control study, a total of 94 cases of women with missed abortion and 188 matched women controls with normal pregnancy but voluntarily abortion were included. The receiver operating characteristic curve (ROC) and the area under the ROC curve (AUC) were used to evaluate the predictive value of AHR signaling pathway genes for missed abortion.

Background: This study aimed to assess trends in surgical site infection (SSI), re-operations for SSI, and re-operations for periprosthetic joint infection (PJI) following primary total hip arthroplasty (THA) in Norway from 2013 to 2022. Two national health registers were used to compare their abilities as surveillance tools for PJI after primary THA.
Methods: The Norwegian Surveillance System for Healthcare-Associated Infections (NOIS) was evaluated for 30-day incidence and risk of SSI and reoperations for SSI after THA.
Clinical and sociodemographic characteristics associated with relapse following electroconvulsive therapy for bipolar disorder.

Objectives: Electroconvulsive therapy (ECT) is an effective treatment for bipolar disorder, but relapse following a successful ECT series is common. We aimed to identify clinical and sociodemographic characteristics associated with the risk of relapse following ECT in bipolar disorder.
Methods: Using data from nationwide Danish registers, we identified all patients receiving their first ECT series with an indication diagnosis of bipolar disorder between 2006 and 2018.
