Prospective and retrospective analysis of whole slide images of sentinel and targeted lymph node frozen sections in breast cancer.

Different types of digital modalities are currently available for frozen section (FS) evaluation in surgical pathology practice. However, there are limited studies that demonstrate the potential of whole slide imaging (WSI) as a robust digital pathology option for FS FS diagnosis. In the current study, we compared the diagnostic accuracy achieved with WSI to that achieved with Light Microscopy (LM) for evaluating FSs of axillary sentinel lymph nodes (SLNs) and clipped lymph nodes (LNs) from breast cancer patients using two modalities.

Estimating relative risks and risk differences in randomised controlled trials: a systematic review of current practice.

Background: Guidelines for randomised controlled trials (RCTs) recommend reporting relative and absolute measures of effect for binary outcomes while adjusting for covariates. There are a number of different ways covariate-adjusted relative risks and risk differences can be estimated.

Objectives: Our goal was to identify methods used to estimate covariate-adjusted relative risk and risk differences in RCTs published in high-impact journals with binary outcomes.

Cost-effectiveness of long-acting progestogens versus the combined oral contraceptives pill for preventing recurrence of endometriosis-related pain following surgery: an economic evaluation alongside the PRE-EMPT trial.

Objectives: To evaluate the cost-effectiveness of long-acting progestogens (LAP), including levonorgestrel-releasing intrauterine system (LNG-IUS) and depot-medroxyprogesterone acetate (DMPA), compared with the combined oral contraceptives pill (COCP) in preventing recurrence of endometriosis-related pain postsurgery.

Design: Within-trial economic evaluation alongside a multicentre, pragmatic, parallel-group, open-label, randomised controlled trial (Preventing Recurrence of Endometriosis by means of Long-Acting Progestogen Therapy trial).

Setting: Thirty-four UK hospitals recruiting participants from November 2015 to March 2019.

Imaging for suspected paediatric ventriculoperitoneal shunt dysfunction: are shunt series X-rays always necessary?

Purpose: Based on an initial hypothesis that the abdominal radiograph is rarely useful in the radiographic shunt series (SS), this study sought to determine which components of the SS are useful in identifying and diagnosing shunt dysfunction. This enquiry broadened to evaluate which modalities were most clinically useful in patients who ultimately underwent shunt revision for their suspected dysfunction.

Methods: Arm1: Abdominal radiographs (AXR) performed over a 2-year period were reviewed retrospectively to identify shunt abnormalities.

Longitudinal clinical and proteomic diabetes signatures in post-gestational diabetes women.

We characterized the longitudinal serum protein signatures of women 6 and 10 years after gestational diabetes mellitus (GDM) to identify factors associated with the development of type 2 diabetes mellitus (T2D) and prediabetes in this at-risk post-GDM population, aiming to discover potential biomarkers for early diagnosis and prevention of T2D. Our study identified 75 T2D-associated serum proteins and 23 prediabetes-associated proteins, some of which were validated in an independent T2D cohort. Machine learning (ML) performed on the longitudinal proteomics highlighted protein signatures associated with progression to post-GDM diabetes.
