A machine learning study involving 4,900 critically ill patients with COPD and sepsis developed a naive Bayes model to predict in-hospital mortality. The model outperformed the SOFA score in internal testing, achieving an AUC of 0.743 versus 0.696, but performance declined to 0.681 during external validation. Prospective multicentre validation is needed before routine clinical use.

The CFTR I556V variant may increase COPD risk by promoting oxidative stress, lung inflammation, and airway remodelling.

CFTR I556V Variant and COPD Risk: Genetic Study Findings

A study investigating 208 patients with COPD and 100 controls identified the CFTR I556V variant as a potential genetic risk factor for COPD, associated with nearly twice the odds of developing the disease. Cell and mouse experiments linked the variant to increased oxidative stress, mitochondrial dysfunction, lung inflammation, and airway remodelling, particularly after cigarette smoke exposure.

Scapular tip free flaps achieved 88.6% dental implant success in patients undergoing midface reconstruction after maxillectomy.

Scapular Tip Flap for Dental Implants After Maxillectomy

A 10-year study of 15 patients undergoing midface reconstruction after maxillectomy found that dental implants placed in scapular tip free flaps achieved an 88.6% success rate. Of the 35 implants placed, four failed during follow-up. All patients received removable implant-supported overdentures, highlighting the scapular tip flap as a potential option for functional dental rehabilitation.

Underweight patients had more complications and longer hospital stays after glossectomy, highlighting the role of BMI in surgical outcomes.

BMI and Surgical Outcomes After Glossectomy: Obesity Paradox

A retrospective study of 6,816 patients undergoing partial or total glossectomy found that underweight patients had the highest complication rate (35.9%) and longest hospital stay (8 days). Overweight and obese patients had shorter stays and fewer complications. The findings suggest that the observed obesity paradox may reflect greater vulnerability among underweight patients rather than a protective effect of excess weight.

A study of temporal bone resection examines reconstruction methods, wound complications, and facial nerve rehabilitation outcomes.

Temporal Bone Resection: Reconstruction and Complication Outcomes

A retrospective study of 140 adults undergoing temporal bone resection found that free flaps were used in 72 cases, with wound dehiscence and infection among the reported complications. Smoking history was associated with wound complications, while prior resection and advanced tumour stage were associated with free flap reconstruction. Facial reanimation procedures were frequently required following facial nerve sacrifice.

Low adherence to healthy dietary patterns was associated with higher oral cavity cancer risk in women in a 30-year study.

Unhealthy Diet and Oral Cavity Cancer Risk in Women

A 30-year analysis of three large US cohorts involving over 210,000 participants found that women with lower adherence to healthy dietary patterns had a higher risk of oral cavity cancer. Low adherence to the Prudent diet and Alternative Healthy Eating Index was associated with 1.86-fold and 2.17-fold higher risks, respectively. No significant associations were observed in men.

BRD4-NUTM1 fusions were linked to poorer survival in head and neck NUT midline carcinoma, a pooled analysis found.

NUT Midline Carcinoma: Tumour Location and Survival Outcomes

A pooled analysis of 81 studies examining head and neck NUT midline carcinoma found that BRD4-NUTM1 gene fusions were associated with significantly poorer overall survival (HR 8.3, 95% CI 4.26–16.23). Tracheo-laryngopharyngeal tumours showed an association with worse survival, while orbito-sinonasal tumours showed a non-significant trend towards better outcomes, suggesting primary tumour location may help guide future prognostic research.
