Tested in 175 participants, the battery demonstrated excellent reliability, with an overall Cronbach’s alpha of 0.977, and an area under the ROC curve of 0.9998. The findings support its potential for culturally appropriate aphasia assessment.

UROLOGY

Study of 52 healthy men finds little difference in urinary flow between sitting and standing, with a small difference in flow timing.

Sitting vs Standing Urination: Effects on Urinary Flow

A randomized crossover study of 52 healthy men compared urinary flow while sitting and standing. Researchers found no statistically significant differences in maximum urinary flow rate or total urine volume between the two positions. However, time to maximum flow was slightly longer while standing. The study did not formally establish equivalence between postures, highlighting the need for larger studies, particularly among men with urinary symptoms.

DERMATOLOGY

Individualized surgery and superficial radiotherapy achieved an 88.1% response rate in 42 patients with sternal keloids.

Sternal Keloid Treatment: Surgery and Radiotherapy Outcomes

A retrospective study of 42 patients with sternal keloids found an 88.1% response rate with individualized surgery followed by superficial radiotherapy and adjunctive scar treatments. At 12 months, scar assessment scores improved across all treatment groups, while recurrence occurred in 11.9% of patients. Radiation dermatitis was reported in three patients and resolved with symptomatic management.

DNA aptamers and alginate–agarose hydrogels show promise for fibrosis treatment, but clinical validation remains limited.

DNA Aptamers and Hydrogels for Keloid and Fibrosis Treatment

A systematic review of 16 studies explored DNA aptamers and alginate–agarose hydrogels as emerging strategies for managing fibrosis, including keloids and hypertrophic scars. Aptamers target profibrotic signalling pathways such as TGF-β and IL-6, while hydrogels support local drug retention and controlled release. However, limited clinical evidence and few integrated approaches highlight the need for further research.

Paul Glaucoma Implant shows comparable 12-month outcomes to Ahmed and Baerveldt devices, but evidence remains limited.

Paul Glaucoma Implant vs Ahmed and Baerveldt Devices

A Bayesian network meta-analysis of five comparative studies involving 238 patients found that the Paul Glaucoma Implant (PGI) achieved broadly comparable intraocular pressure and glaucoma medication reductions to the Ahmed Glaucoma Valve and Baerveldt Glaucoma Implant over 12 months. However, evidence certainty was low to very low, highlighting the need for larger randomised trials and longer follow-up.

ENDO-DIABETOLOGY

Front-of-pack warning labels reduce sugar consumption, but their effects on socioeconomic inequalities remain inconsistent.

Front-of-Pack Food Labels and Sugar Consumption Inequality

A systematic review of 10 studies found that front-of-pack food labels, particularly warning labels, reduced sugar consumption at the population level. However, their impact on socioeconomic inequalities was inconsistent, with studies reporting greater benefits among both higher- and lower-income groups. Poor overall study quality highlights the need for robust longitudinal research to assess equitable outcomes.

GYNAECOLOGY - IVF

A study of 10,009 IVF pregnancies links early ultrasound findings with viability and identifies a potential miscarriage threshold.

Early Ultrasound Findings and Miscarriage Risk in IVF Pregnancies

A multicenter study of 10,009 IVF pregnancies found significant differences in early crown–rump length (CRL) measurements between pregnancies that remained viable and those that ended in miscarriage. An empty gestational sac at 47 days or later after embryo transfer showed 100% positive predictive value and specificity for miscarriage in the study cohort. External validation is needed before clinical application.

Zumba improves cardiorespiratory fitness and reduces body fat in inactive women, although BMI changes are not significant.

Zumba Benefits for Fitness and Body Fat in Inactive Women

A systematic review and meta-analysis of seven randomized controlled trials found that Zumba significantly improved cardiorespiratory fitness and reduced body fat percentage in physically inactive women.
