Influenza causes considerable morbidity and mortality in Europe, particularly among older adults due to comorbidities, as well as immunosenescence and inflammaging, which contribute to a diminished immune response. Vaccination remains the most effective way to prevent poor outcomes; however, uptake is suboptimal and many countries recommend standard vaccines despite evidence supporting better protection with enhanced (adjuvanted and high-dose) vaccines.

A multidisciplinary group of experts reviewed the burden of influenza in Europe and evaluated data on enhanced vaccines, providing recommendations for their use in older adults. The group discussed barriers to vaccination and strategies to increase uptake.

Improving protection of older adults against influenza relies upon increasing vaccine uptake and ensuring access to vaccines that overcome age-related immunological decline. Achieving higher uptake requires national policies that facilitate equitable access and clear communication about vaccine eligibility. Based on available evidence, enhanced vaccines offer better protection than standard vaccines against hospitalization and complications in older adults. National recommendations should prioritize the use of enhanced influenza vaccines over standard vaccines in older adults. Limitations to interpretation of evidence include discrepancies in reporting of influenza-related medical encounters and underreporting of influenza-related complications.

Morphological MRI can describe the brain structures and bleeding location but cannot describe the hydrocephalus' mechanisms in intraventricular hemorrhage (HIVH) in preterms. We have shown previously that phase-contrast MRI (PCMRI) can be used to quantify cerebral blood and CSF dynamics in newborns. The objective of the present study was to evaluate the impact of HIVH on CSF oscillations and blood flows in premature infants with hydrocephalus.

Fifteen preterm infants with HVIH underwent morphological MRI and PCMRI between 3 weeks and 6 years after birth. We used PCMRI to quantify CSF flows in the aqueduct of Sylvius and in the spinal canal.

Different morphological types of hydrocephalus were observed. We found communicating and obstructive hydrocephalus. We found different hydrodynamic behaviors at intraventricular and subarachnoid levels. The morphological analysis of the spinal canal did not systematically correspond to the PCMRI results. At the aqueduct, the results were concordant in three cases only.

PCMRI can quantify CSF and blood flows in newborns, reveal abnormally low or high CSF flows when a morphologic analysis cannot, and provide information that complements the morphological analysis and might be useful for understanding the physiopathology of the condition.

The value of a bridge in loop ileostomies is debated. We aimed to evaluate whether using a bridge when creating a loop ileostomy can reduce morbidity following an ileostomy.

Patients who had a loop ileostomy after elective colorectal surgery from January 2016 to July 2022 were randomized in this multicenter phase 2 randomized superiority trial. The primary endpoint was the absence of postoperative stomal complications at 2 months and was assessed in a blinded fashion by a stoma therapist. Secondary endpoints were morbidity at 1 month and the STOMA-QOL score at 2 months.

During the study period, 67 patients were randomized to the bridge group and 63 to the no-bridge group. Epidemiological and perioperative data did not differ between the two groups. The stomal complication-free rate was 76% in the bridge group and 67% in the no-bridge group (p = 0.3). There was no difference in the distribution of complications at 1 month according to the Clavien-Dindo score (p = 0.2) or the STOMA-QOL score at 2 months (p = 0.4) between the two groups.

The bridge does not reduce the rate of stomatal complications, nor does it appear to reduce patients' quality of life.
