Diagnostic Accuracy of Point-Of-Care Ultrasound for Paediatric Testicular Torsion
The present systematic review and meta-analysis showed that POCUS had high sensitivity and specificity for identifying testicular torsion in paediatric patients although the risk of bias was high in the studies analysed.

A Systematic Review And Meta-Analysis
[Posted 17/May/2022]
AUDIENCE: Emergency Medicine, Pediatric
KEY FINDINGS: The present systematic review and meta-analysis showed that POCUS had high sensitivity and specificity for identifying testicular torsion in paediatric patients although the risk of bias was high in the studies analysed.
BACKGROUND: Previous studies have examined the utility of ultrasonography performed by radiologists for diagnosing paediatric testicular torsion. While point-of-care ultrasound (POCUS) is used in paediatric emergency medicine, its diagnostic accuracy is still unknown. The present systematic review and meta-analysis aimed to clarify the accuracy of POCUS in diagnosing testicular torsion in children.
DETAILS: Following the Preferred Reporting Items for Systematic Review and Meta-analysis of Diagnostic Test Accuracy guidelines, a systematic review was performed. Any study investigating the diagnostic accuracy of POCUS for paediatric testicular torsion was extracted. The primary outcome was the assessment of the diagnostic accuracy of POCUS for paediatric testicular torsion. The pooled sensitivity and specificity were calculated. Quality analysis was conducted using Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2). Four studies enrolling 784 patients in total were included. The pooled sensitivity, specificity, and positive and negative likelihood ratios of POCUS were 98.4% (95% CI: 88.5% to 99.8%), 97.2% (95% CI: 87.2% to 99.4%), 34.7 (95% CI: 7.4 to 164.4) and 0.017 (95% CI: 0.002 to 0.12), respectively. Risk-of-bias assessment using QUADAS-2 revealed that two of the studies had a high risk of bias in patient selection.

Comparative Effectiveness and Safety of Pharmacological Treatments for Rapid Tranquilisation in Emergency Settings
This IPD network meta-analysis suggests that antipsychoticbenzodiazepine combinations may offer the greatest efficacy for rapid tranquilisation in emergency settings. However, the very low certainty of evidence and study heterogeneity underscore the need for individualized treatment decisions and further high-quality randomized trials.

Gadolinium-Based Contrast Agents: Reassessing Safety Beyond Nephrogenic Systemic Fibrosis
This review highlights that gadolinium-based contrast agents continue to play a critical role in diagnostic MRI, but their use should be guided by careful patient selection and individualized risk assessment. Although the risk of nephrogenic systemic fibrosis has declined considerably, further research is needed to clarify the clinical significance of gadolinium retention and its long-term safety.

Promising Drug Candidates and Emerging Therapeutic Strategies Against Candida auris
Emerging therapies for Candida auris extend beyond conventional antifungal agents and include repurposed drugs, novel antifungal compounds, vaccines, antimicrobial peptides, and nanotechnology-based approaches. While further clinical validation is needed, these strategies may help address the growing challenge of multidrug-resistant C. auris infections.

Ensitrelvir for Covid-19 Postexposure Prophylaxis in Household Contacts
Early initiation of a 5-day oral ensitrelvir regimen within 72 hours after symptom onset in an index patient significantly reduced the risk of developing Covid-19 among household contacts while maintaining a safety profile comparable to placebo. Clinical benefit was observed across major patient subgroups, including individuals at increased risk for severe disease, and treatment was associated with reduced household transmission. These findings support ensitrelvir as an effective postexposure prophylactic option for household contacts and suggest potential utility in other high-risk exposure settings where rapid outbreak control is needed.

Ambulatory Antibiotic Prescribing for Acute Sinusitis
Overall, approximately one-third of patients with acute sinusitis did not meet guideline-based indications for antibiotic therapy, yet antibiotics continued to be prescribed frequently in this population. These findings highlight opportunities for antimicrobial stewardship initiatives to improve both prescribing frequency and treatment duration, particularly in clinical settings where adherence to recommended practices is suboptimal, while monitoring potential unintended effects such as repeat healthcare utilization.
