Objective: This study aimed to develop and validate a smartphone-based ML app to predict bilirubin (SpB) levels in multiethnic neonates using skin color analysis.

Design, Setting, And Participants: This diagnostic study was conducted between June 2022 and June 2024 at a tertiary hospital and 4 primary-care clinics in Singapore with a consecutive sample of neonates born at 35 or more weeks' gestation and within 21 days of birth.

Thermographic and ultrasound assessment in patients with rheumatoid arthritis: can thermography detect subclinical synovitis at the wrist?

Background: Thermography is an emerging imaging modality which allows for a quick and objective measure of joint surface temperature in patients with rheumatoid arthritis (RA). To date, there are no published studies comparing thermography with ultrasonography in the subclinical assessment of joint inflammation at the wrist of patients with RA, and no published data on inter-rater reliability for multiple raters for thermographic assessment at the RA wrist. In our study comparing thermography and ultrasonography at the RA wrist, we aim to determine if thermography can detect subclinical synovitis.

Outcomes of total knee replacement versus unicompartmental knee arthroplasty in an enhanced recovery after surgery protocol.

Introduction: Unicompartmental Knee Arthroplasty (UKA) has become popular due to faster recovery and improved range of motion. However, concerns have been made regarding increased risk of early failure. Furthermore, the use of Enhanced Recovery After Surgery (ERAS) protocols have shown to allow faster return to activities, improved satisfaction, and reduced complication rates.

Subclinical joint inflammation in rheumatoid arthritis: comparing thermal and ultrasound imaging at the metacarpophalangeal joint.

Background: While ultrasound and MRI are both superior to clinical examination in the detection of joint inflammation, there is presently a lack of data whether thermography may be similarly useful in the assessment of joint inflammation in patients with RA. Our study aims to evaluate the use of thermography in detecting subclinical joint inflammation at clinically quiescent (non-tender and non-swollen) metacarpophalangeal joints (MCPJs) in patients with rheumatoid arthritis (RA). The outcomes from thermography in our study will be compared with ultrasonography (which is a more established imaging tool used for joint inflammation assessment in RA).

Long-term effectiveness and persistence rate of ustekinumab dose intensification in a South East Asian inflammatory bowel disease center.

Background And Aims: Ustekinumab (UST) is an effective biologic for treatment of inflammatory bowel disease (IBD). However, some patients treated with UST have suboptimal clinical response with standard dosing. The aims of this study were to determine the effectiveness of UST dose intensification (DI), identify factors associated with DI, cumulative incidence of DI and persistence of UST among treated patients.

Assessment of joint inflammation at the wrist of patients with rheumatoid arthritis: thermography findings closely mirror those from ultrasonography.

Objectives: To determine if thermography (in comparison with ultrasonography) may be helpful in detecting joint inflammation at the RA wrist categorised according to its clinical manifestations.

Methods: Four wrist groups were derived from the right wrist of RA subjects as follows: (1) swollen; tender (S1T1); (2) swollen; non-tender (S1T0); (3) non-swollen; tender (S0T1); (4) non-swollen; non-tender (S0T0). Thermographic parameters included the maximum (Tmax), average (Tavg) and minimum (Tmin) temperatures.

Relationship between CGM-derived nocturnal hypoglycemia and subjective sleep quality in people with type 1 diabetes.

This pilot study explores the relationship between nocturnal hypoglycemia (NH) and subjective sleep quality in people with type 1 diabetes (T1D). Twenty-seven adults with T1D wore a Freestyle Libre Pro CGM and recorded subjective sleep quality daily, as assessed by a single Likert scale question. Frequency, duration, area under the curve (AUC) of NH (00:00-06:00) defined as sensor glucose below threshold (< 3.

Association of Smartphone-Based Activity Tracking and Nocturnal Hypoglycemia in People With Type 1 Diabetes.

Background: Nocturnal hypoglycemia (NH) remains a major burden for people with type 1 diabetes (T1D). Daytime physical activity (PA) increases the risk of NH. This pilot study tested whether cumulative daytime PA measured using a smartphone-based step tracker was associated with NH.

Appropriateness of lumbar spine radiography and factors influencing imaging ordering patterns: paving the path toward value-driven health care.

The demand for diagnostic imaging continues to rise. Against the backdrop of rising health care costs and finite resources, this has prompted a paradigm shift toward value-driven patient care. Inappropriate imaging is a barrier toward achieving this goal, which runs counter to prevailing evidence-based guidelines and contributes to rising healthcare costs.

Prognostic Value of Tumor Budding in Urothelial Carcinoma: A Meta-Analysis and Systematic Review.

Recently, tumor budding (TB) has been suggested as a strong prognostic marker in urinary tract urothelial carcinoma (UC). The aim of this systematic review is to test the prognostic value of TB in UC by a meta-analysis of previously published studies. We systematically reviewed the literature related to TB by using the databases of Scopus, PubMed, and Web of Science.
