ROX-HR Index Shows Early Predictive Value for Conventional Oxygen Therapy Outcomes in Acute Respiratory Failure
The ROX index and ROX-HR index demonstrate favorable diagnostic performance in predicting the treatment outcomes of conventional oxygen therapy in patients with acute respiratory failure. These indicators show potential as reliable predictive tools and may serve as dynamic monitoring indices for evaluating the efficacy of conventional oxygen therapy, although further prospective studies with larger sample sizes are warranted to validate their clinical utility.

T-Wave Morphology Variation Improves Risk Stratification in Type 2 Long-QT Syndrome Beyond QTc Duration
This study demonstrates that the TMV index provides prognostic information beyond QTc duration in patients with LQT2. More negative TMV values were independently associated with an increased lifetime risk of cardiac events, whereas T-wave amplitude and the morphology combination score were not predictive of outcomes. TMV may enhance ECG-based risk stratification, particularly in patients with borderline or prolonged QTc intervals, pending validation in larger prospective multicenter studies.

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.
