Department of Vitreoretinal Services, Aravind Eye Hospital, Madurai (Tamil Nadu), India.
To investigate the use of short-term postoperative endotamponade with perfluorocarbon liquids (PFCLs) for the treatment of giant retinal tear-associated rhegmatogenous retinal detachment (RRD). This retrospective study evaluated patients who had 2-stage surgery, which entailed pars plana vitrectomy (PPV) completed in 2 consecutive surgeries spaced 5 days apart, during which a short-term tamponade with PFCL was used (Group 1), and patients who had conventional single-stage PPV with long-term silicone oil (SO) tamponade (Group 2). The study comprised 74 eyes of 68 patients, 52 in Group 1 and 22 in Group 2.

Purpose: This study aimed to design and evaluate a prior-knowledge-guided U-Net (PK-UNet) for automatic clinical target volume (CTV) segmentation in postmastectomy radiation therapy for breast cancer.
Methods And Materials: A total of 102 computed tomography (CT) scans from breast cancer patients who underwent postmastectomy were retrospectively collected. Of these, 80 scans were used for training with 5-fold cross-validation, and 22 scans for independent testing.

Article Synopsis
- Atrial fibrillation (AF) is categorized by duration into paroxysmal, persistent, and long-standing persistent types, with longer durations increasing the risk of recurrence during catheter ablation treatment.
- The study aims to enhance the diagnosis accuracy of AF duration through a predictive model, utilizing data from 272 patients to train a machine learning algorithm.
- Results showed the model achieved 81.8% accuracy in predicting AF duration, significantly improving cardiologists' diagnostic performance from 63.9% to 71.6% after using the model's insights.
Recommendations for monitoring adherence and fidelity in pragmatic trials based on experience in the Pain Management Collaboratory.

Pain Management Collaboratory Coordinating Center, Yale University, New Haven, CT 06519, United States.
Objective: Most pragmatic trials follow the PRagmatic Explanatory Continuum Indicator Summary (PRECIS-2) criteria. The criteria specify unobtrusive measurement of participants' protocol adherence and practitioners' intervention fidelity but suggest no special monitoring strategies to assure trial integrity. We present experience with adherence/fidelity monitoring in the Pain Management Collaboratory (PMC) and provide recommendations for their monitoring in pragmatic trials to preserve inferences of treatment comparisons.
