CRITICAL CARE

Staphylococcus aureus and Pseudomonas aeruginosa often infect the airways in cystic fibrosis (CF). Because registry studies show higher prevalence of P. aeruginosa versus S. aureus in older patients with CF, a common assumption is that P. aeruginosa replaces S. aureus over time. In vitro, P. aeruginosa can outgrow and kill S. aureus.

Neutrophilic Inflammation May Predict Reduced Symptom Improvement After Sinus Surgery in CRSwNP

Complete functional endoscopic sinus surgery (FESS) significantly improved quality of life in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). In a retrospective study of 207 patients, tissue neutrophilia was associated with less improvement in SNOT-22 scores, particularly when tissue eosinophilia was also high. Combining histopathology with the Completeness of Surgery Index may help guide postoperative treatment decisions.

Study findings highlight low-frequency music perception challenges in cochlear implant users compared with hearing aid users.

Music Perception in Hearing Aid and Cochlear Implant Users

A cross-sectional study of 52 adults found that bilateral hearing aid users were more sensitive to low-frequency sound degradation in music than cochlear implant users. At 200 and 400 Hz, hearing aid users reported better sound quality, while differences disappeared at 800 Hz. The findings highlight music perception challenges after cochlear implantation and support counseling candidates about postoperative listening experiences.

Study explores how birth satisfaction and resilience may help explain the association between prenatal anxiety and postpartum depression.

Prenatal Anxiety, Birth Satisfaction and Postpartum Depression

A study of 635 women in China found that birth satisfaction and psychological resilience showed significant indirect associations between prenatal anxiety and postpartum depressive symptoms at six weeks. Resilience accounted for 30.26% of the total statistical association, while birth satisfaction accounted for 17.34%. The findings highlight the potential importance of psychological support during pregnancy and positive childbirth experiences in postpartum mental health.

GASTROENTEROLOGY

A study of patients with PSC found that brush cytology had a 0.99 negative predictive value, while ERC score and serum IgG4 improved risk prediction for biliary dysplasia and cholangiocarcinoma-related outcomes.

Brush Cytology for Cholangiocarcinoma Surveillance in PSC

A study evaluating 4,017 brush cytology samples from 984 patients with primary sclerosing cholangitis (PSC) assessed the detection of biliary dysplasia and cholangiocarcinoma (CCA). Brush cytology demonstrated a negative predictive value of 0.99 and an overall accuracy of 0.91. The endoscopic retrograde cholangiography (ERC) score and serum IgG4 were identified as key predictors of biliary dysplasia and CCA-related outcomes. Combining these markers improved predictive performance, potentially supporting more individualized surveillance strategies in patients with PSC.

A genetic association study linked homozygous MUC13 p.Arg503Ser to elevated transferrin saturation and identified a potential role for MUC13 in intestinal iron absorption.

MUC13 Genetic Variant and Unexplained Hyperferritinemia

A sequencing-based genetic association study identified the MUC13 p.Arg503Ser variant as a potential contributor to unexplained hyperferritinemia, particularly in individuals homozygous for the 503Ser allele. The discovery was validated in an independent cohort of 263 patients, where the homozygous genotype was associated with elevated transferrin saturation (OR 4.52; 95% CI 1.55–13.19). Functional experiments in mice and human intestinal cell models supported a role for MUC13 in intestinal iron absorption. These findings may improve understanding of the genetic mechanisms underlying unexplained elevations in ferritin and iron levels.

A survey of 1,436 patients with rheumatologic conditions found that balanced THC-CBD products were associated with higher positive impact scores, while some formulations were linked to more reported side effects.

Cannabis Products and Patient-Reported Outcomes in Rheumatology

A survey of 1,436 cannabis-using patients with rheumatologic conditions in Alberta, Canada, examined associations between cannabis product characteristics and patient-reported outcomes. Products with balanced tetrahydrocannabinol (THC) and cannabidiol (CBD) content were associated with higher positive impact scores (adjusted OR 1.76; 95% CI 1.18–2.63). Edible products and dried cannabis were also associated with higher positive impact scores. However, THC-dominant products were associated with increased dampening and sensory effects, while dried cannabis was linked to several reported side effects. These findings highlight variability in patient experiences and the importance of considering product composition and formulation.

A national study found that greater neighborhood socioeconomic deprivation was associated with worse physical function and a higher likelihood of functional decline among adults with SLE.

Neighborhood Deprivation and Physical Function in Systemic Lupus Erythematosus

A national electronic health record-based study examined the relationship between neighborhood socioeconomic disadvantage and functional status among adults with systemic lupus erythematosus (SLE). In the cross-sectional cohort of 20,620 patients, those living in the most deprived neighborhoods had worse adjusted mean functional status scores than those in the least deprived neighborhoods. In the longitudinal cohort of 10,604 patients, functional decline occurred in 17.0% of patients in the most deprived quintile, compared with 11.4% in the least deprived quintile. The findings highlight the potential importance of addressing socioeconomic barriers alongside clinical care to improve functional outcomes in SLE.

A longitudinal lupus nephritis study found that lower baseline eGFR, chronic kidney damage, and incomplete early clinical response were associated with long-term kidney function loss.

Predictors of Long-Term Kidney Outcomes in Lupus Nephritis

A longitudinal study of 172 patients with lupus nephritis (LN) from the Accelerating Medicines Partnership cohort investigated predictors of long-term kidney function loss over a median follow-up of 4.6 years. Kidney function loss occurred in 33% of patients. Lower baseline estimated glomerular filtration rate (eGFR), greater chronic histologic damage, and failure to achieve a complete clinical response at 3, 6, or 12 months were associated with increased risk. Proteinuria below 0.7 g/g at 12 months was associated with better outcomes, although it did not guarantee kidney protection. The findings highlight the need for improved biomarkers to assess treatment response and predict long-term kidney outcomes.

A study of 286 postpartum women in Turkey found that inadequate labor information and several obstetric practices were associated with higher reported obstetric violence scores.

Obstetric Violence and Associated Factors in Maternity Care in Turkey

A cross-sectional study of 286 women who gave birth in Turkey examined reported obstetric violence and its associated factors during the first postpartum year. Multivariable analysis identified lack of information during labor, prolonged bed rest, prolonged fasting, continuous non-stress testing, vacuum extraction, fundal pressure, and postpartum complications as factors independently associated with higher Obstetric Violence Scale scores. Lack of information during labor was associated with a 2.40-fold adjusted rate, while prolonged bed rest showed a 3.07-fold adjusted rate. The findings emphasize the importance of respectful maternity care, informed consent, clear communication, and careful assessment of obstetric interventions.

TIR-defined cam morphology was associated with hip osteoarthritis development over 10 years, supporting its potential role in risk assessment.

Triangular Index Ratio for Predicting Hip Osteoarthritis Risk

A 10-year follow-up study involving 1,002 participants found that cam morphology defined by a triangular index ratio (TIR) of ≥1.05 was associated with the development of radiographic hip osteoarthritis. TIR-defined cam morphology was linked to 2.48 times higher adjusted odds of osteoarthritis. Compared with the conventional alpha angle, TIR showed a higher positive predictive value, although both methods had low sensitivity.

Olfactory training may improve smell-related quality of life and cognition, but its effects on depression remain uncertain.

Olfactory Training May Improve Quality of Life and Cognition

A systematic review of 51 studies found that olfactory training (OT) may improve smell-related quality of life and cognitive performance in people with olfactory dysfunction. Controlled trials showed greater quality-of-life improvement with OT than without training. However, no significant benefit was observed for depressive symptoms, highlighting the need for further research.
