The aim of this study was to isolate several species of Corynebacterium using an established protocol that led to the previous isolation of C. durum. Characterization of C. durum interspecies interactions revealed a specific mechanism for chain elongation in Streptococcus sanguinis that was the result of corynebacterial fatty acid production and secretion. While the protocol was successfully applied to isolate what we presumed to be additional Corynebacterium based on several phenotypic traits that seem to be identical to C. durum, genome sequencing of the newly isolated strains placed them closer to Actinomyces. Furthermore, it seems to be important to test common core phenotypes in bacterial ecology to understand the behavior of specific groups of microbes, rather than simply relying upon genome sequence homology to establish relationships in the microbiome.

GYNAECOLOGY - IVF

A cost-effectiveness model found that contingent NIPT strategies reduced false positives and invasive procedures, while universal NIPT required substantially lower prices to compete economically.

Contingent vs Universal NIPT: Cost-Effectiveness Across Healthcare Systems

A deterministic decision-analytic cohort model involving 1,000,000 pregnancies compared universal non-invasive prenatal testing (uNIPT) with contingent NIPT strategies across public, university, and private healthcare tariff systems. The analysis evaluated trisomy detection, false-positive and missed cases, invasive procedures, procedure-related fetal loss, short-term psychological quality-adjusted life year (QALY) losses, and healthcare costs. Contingent NIPT strategies substantially reduced false-positive results and invasive procedures, resulting in the lowest short-term QALY losses. In the full incremental cost-effectiveness analysis, Reflex300 was the only strategy on the cost-effectiveness frontier in private-sector scenarios, while CT and Reflex300 remained on the frontier in public-sector (SUT) and university scenarios.

High PD-1 expression in CD8⁺ T cells was associated with Atez/Bev response in HCC, while BCAA metabolism and BCAT1 expression highlighted liver-specific mechanisms of antitumor immunity.

PD-1 and BCAA Metabolism May Predict Immunotherapy Outcomes in Liver Cancer

A study investigating hepatocellular carcinoma (HCC) patients treated with atezolizumab plus bevacizumab (Atez/Bev) explored potential biomarkers of treatment response and the role of tumor-specific metabolism. High programmed cell death-1 (PD-1) expression in CD8⁺ tumor-infiltrating lymphocytes (TILs) was associated with therapeutic response, independent of disease etiology. RNA sequencing revealed enrichment of branched-chain amino acid (BCAA)-related metabolic pathways in tumors with high PD-1 expression in CD8⁺ TILs. In vitro experiments further demonstrated the importance of BCAAs in CD8⁺ T-cell activation and differentiation.

NEUROLOGY

Combining machine learning–derived brain imaging signatures with plasma biomarkers may improve Alzheimer’s disease detection and prediction of cognitive impairment.

Brain Imaging and Plasma Biomarkers Improve Alzheimer’s Disease Prediction

A study involving 1,297 participants without dementia evaluated machine learning–derived neuroimaging signatures for brain aging (SPARE-BA) and Alzheimer’s disease (SPARE-AD). SPARE-AD showed the strongest association with plasma phosphorylated tau 217 (p-tau217), while SPARE-BA correlated most strongly with plasma neurofilament light (NfL). Combining neuroimaging signatures with plasma biomarkers improved diagnostic discrimination and prediction of cognitive impairment, highlighting their potential for early detection and disease progression monitoring.

A randomized trial found that ultrasound-guided pushing reduced second-stage labor duration, significant perineal tears, and intrapartum fever in first-time mothers.

Ultrasound-Guided Pushing Reduces Labor Duration and Perineal Tears

A single-center randomized controlled trial involving 327 nulliparous women receiving epidural analgesia found that transperineal ultrasound (TPUS)-guided visual biofeedback delivered by midwives significantly reduced the duration of the second stage of labor compared with traditional coaching (107 vs 132 minutes; P = 0.001). The intervention also reduced second-degree or higher perineal tears (65.4% vs 77.3%; P = 0.020) and intrapartum fever (8.9% vs 16.4%; P = 0.043). However, the mode of delivery and key neonatal outcomes did not differ significantly. Larger studies are needed to confirm these findings and assess broader clinical benefits.

A retrospective study found that women with a previous second-stage cesarean experienced shorter labor during subsequent VBAC attempts than women with a previous elective cesarean.

Previous Labor Progress May Predict VBAC Duration

A retrospective study of 200 women attempting vaginal birth after cesarean (VBAC) at a tertiary maternity hospital in Germany found that the stage of labor reached during a previous pregnancy was associated with the duration of subsequent labor. VBAC was achieved in 75.5% of participants. Median labor duration was 12.2 hours after a previous elective cesarean, 10 hours after a cesarean during the first stage of labor, and 8 hours after a cesarean during the second stage. These findings suggest that greater cervical dilation during a previous labor may be associated with faster subsequent VBAC, although further research is needed to confirm the relationship.

Levonorgestrel, etonogestrel, and clomifene showed the strongest disproportionate reporting signals, while 16 drugs emerged as potential novel safety signals. These findings may guide further drug-safety research but do not establish causation or confirm increased ectopic pregnancy risk.

Trial finds ex utero cord blood collection comparable to standard collection in weight, cellular composition, and contamination.

Ex Utero vs In Utero Umbilical Cord Blood Collection

A randomized clinical trial involving 101 umbilical cord blood collections found that ex utero collection, performed after placental delivery, was non-inferior to standard in utero collection in terms of blood unit weight. Cellular composition and bacterial contamination rates were also comparable, supporting ex utero collection as a clinically viable alternative that may improve maternal comfort during childbirth and facilitate cord blood donation.

Study links prior concussion to persistent choice reaction-time slowing in collegiate athletes, despite adjusted cognitive scores.

Concussion History and Reaction Time in Collegiate Athletes

A study of 547 NCAA Division I athletes found that those with a history of concussion had significantly slower choice reaction times than matched controls, even after adjusting for memory, concentration, and cognitive performance. No significant differences were observed in simple reaction time, Stroop reaction time, or shifting-attention reaction time, suggesting that choice reaction time may help detect subtle, persistent neurocognitive deficits after concussion.

Study highlights sexual health disparities among transgender individuals, emphasizing inclusive care and policies addressing stigma.

Sexual Health and Vulnerability Among Transgender Individuals

A cross-sectional study of 74 transgender individuals in São Paulo, Brazil, found differences in relationship status, sexual partnerships, and sex work between trans women and trans men. Trans women were more frequently single (76% vs 44.9%) and more likely to report sex work (21.7% vs 6.3%). The findings highlight the need for inclusive sexual health services and policies addressing stigma and structural inequalities.

Meta-analysis links tumor budding to poorer survival in endometrial cancer, highlighting the need for further validation.

Tumor Budding as a Prognostic Marker in Endometrial Cancer

A systematic review and meta-analysis of 10 studies involving 1,307 patients found that tumor budding was associated with poorer progression-free survival (HR 2.44) and overall survival (HR 1.89) in endometrial cancer. However, evidence linking tumor budding to lymph node metastasis was inconsistent. Standardized assessment and validation in larger, molecularly stratified studies are needed to establish its prognostic value.
