Objective: This study aimed to evaluate the anatomical and functional outcomes of secondary pars plana vitrectomy (PPV) after failed scleral buckling (SB) surgery and to compare it with primary PPV for rhegmatogenous retinal detachment (RRD), including complicated proliferative vitreoretinopathy cases.
Design: Retrospective series in a tertiary care centre.
Participants: One hundred and twenty consecutive patients.
Methods: The medical records of patients who underwent PPV with silicone oil tamponade for RRD were reviewed. Forty-four eyes were operated on for primary RRD (primary PPV group), and 76 eyes were operated on for failed SB surgery (secondary PPV group). The single-operation anatomical success rate, final anatomical success rate, and best-corrected visual acuity preoperatively, at 6 months, at 1 year, and at final follow-up were analyzed.
Results: The single-operation anatomical success rate was 74.2% in the primary PPV group and 77% in the secondary PPV group (p = 0.48). The final anatomical success rate was 90.3% in the primary PPV group and 91.8% in the secondary PPV group (p = 0.55). The number of cases with visual acuities of 3 visual categories (20/50 or better, 20/200 to 20/50, less than 20/200) was not statistically different at each time point.
Conclusions: Consequent PPV with silicone oil tamponade for failed SB surgery seems not to have inferior anatomical and functional outcomes when compared with primary PPV for RRD.

Background: This study aims to identify optimal acceleration factors (AFs) for compressed sensing (CS) technology to enhance its clinical application for suspected coronary artery disease (CAD) in whole-heart non-contrast coronary magnetic resonance angiography (CMRA).
Methods: Two hundred and seventeen individuals with suspected CAD underwent whole-heart non-contrast CMRA on a 1.5-T CMR scanner with CS AFs of 2, 4, and 6 (CS2, CS4, and CS6).
Expanded non-invasive prenatal testing offers better detection of fetal copy number variations but not chromosomal aneuploidies.

Purpose: To evaluate the clinical performance of expanded non-invasive prenatal testing (NIPT-plus) and compare its effectiveness in screening for chromosomal aneuploidies with that of NIPT.
Methods: Screening results, confirmatory invasive testing results, and follow-up data from pregnant women who underwent either NIPT (6792 cases) or NIPT-Plus (5237 cases) testing at Luohe Central Hospital, China, from January 2019 to June 2023 were collected. The positive predictive value (PPV), sensitivity, specificity, and other indicators for different types of chromosomal abnormalities in NIPT/NIPT-plus screening were calculated.

Background: Subcutaneous immunoglobulin (SCIg) replacement therapy is indicated for patients with hypogammaglobulinemia caused by primary (PID) and secondary immunodeficiencies (SID).
Objective: To compare healthcare resource utilization (HCRU) and related direct medical costs of patients in France treated with weekly conventional SCIg (cSCIg) vs monthly hyaluronidase-facilitated SCIg (fSCIg).
Methods: This retrospective study of Ig-naïve patients with PID or SID newly receiving a SCIg between 2016 and 2018, extracted from the French National Healthcare reimbursement database (SNDS), analyzed the SCIg-related HCRU and reimbursed costs generated from in-hospital (hospitalizations and SCIg doses) or at-home (nurse visits [NV] and pump provider visits [PPV], drug doses) SCIg administration.

(PCV2) is the main and primary causative agent of Postweaning Multisystemic Wasting Syndrome (PMWS). To date, immunoperoxidase monolayer assay (IPMA), indirect immunofluorescent assay (IFA), and enzyme linked immunosorbent assay (ELISA) are the most commonly diagnostic methods for detecting PCV2 antigens. However, these methods require specialized equipment and technical expertise and are suitable for laboratory use only.

Screening tests for disease have their performance measured through sensitivity and specificity, which inform how well the test can discriminate between those with and without the condition. Typically, high values for sensitivity and specificity are desired. These two measures of performance are unaffected by the outcome prevalence of the disease in the population.
