Hypophosphatemia appears to be a marker of disease severity. Limited number of available studies and varied study designs did not allow for the ascertainment of the effect of severe hypophosphatemia on patient mortality.

Hypophosphatemia in ICU was associated with increased hospital and ICU length of stay but not all-cause mortality. Hypophosphatemia appears to be a marker of disease severity. Limited number of available studies and varied study designs did not allow for the ascertainment of the effect of severe hypophosphatemia on patient mortality.

To determine the impact of women's age on the cesarean section (CS) rate according to Robson groups 1, 2A, 3 and 4A.

Retrospective cohort study of term, livebirth, singleton pregnancies with spontaneous or induced labor who delivered at the San Paolo Hospital from 1996 through 2019, and had the Robson group assigned. Women were grouped in 5 age classes (≤24, 25-29, 30-34, 35-39 and ≥40 years). The primary outcome was the rate of CS.

24 843 women were included 36.4% classified as Robson group 1, 18.9% as Robson group 2A, 34.4% as Robson group 3 and 10.2% as Robson group 4A. The CS rate of women in Robson groups 1, 2A, 3 and 4A was 6.6%, 21.8%, 1.6% and 4.3% respectively. In nulliparous women [Robson groups 1 and 2A] group 1, the adjusted OR of CS increased steadily from 30 to ≥40 years, when compared to women aged 25-29 years. On the contrary, in multiparous women [Robson groups 3 and 4A] significant increased OR were present only for women ≥40 years. In young women [≤24 years] there was a significant reduction in the number of cesarean sections only in Robson group 1.

The results of our study show that multiparous women aged ≥40, either in spontaneous or induced labor have an independent twofold increased risk of delivering by cesarean section when compared to women of 25-29 years. On the contrary, in nulliparous women, the risk slightly, but significantly, increases with age and again becomes twofold in women ≥40 years.

The role of the carotid siphon within the whole ICA trajectory in pulsatility attenuation is still poorly understood. This study aims to assess arterial variances in velocity pulsatility and distensibility over the whole ICA trajectory, including effects of age and sex. Methods and Results We assessed arterial velocity pulsatility and distensibility using flow-sensitized 2-dimensional phase-contrast 3.0 Tesla magnetic resonance imaging in 118 healthy participants. Velocity pulsatility index (vPI=(Vmax-Vmin)/Vmean) and arterial distensibility defined as area pulsatility index (Amax-Amin)/Amean) were calculated at C1, C3, and C7 segments of the ICA. vPI increased between C1 and C3 (0.85±0.13 versus 0.93±0.13, P less then 0.001 for averaged right+left ICA) and decreased between C3 and C7 (0.93±0.13 versus 0.84±0.13, P less then 0.001) with overall no effect (C1-C7). Conversely, the area pulsatility index decreased between C1 and C3 (0.18±0.06 versus 0.14±0.04, P less then 0.001) and increased between C3 and C7 (0.14±0.04 versus 0.31±0.09, P less then 0.001). vPI in men is higher than in women and increases with age (P less then 0.015). vPI over the carotid siphon declined with age but remained stable over the whole ICA trajectory. Conclusions Along the whole ICA trajectory, vPI increased from extracranial C1 up to the carotid siphon C3 with overall no effect on vPI between extracranial C1 and intracranial C7 segments. This suggests that the bony carotid canal locally limits the arterial distensibility of the ICA, increasing the vPI at C3 which is consequently decreased again over the carotid siphon. In addition, vPI in men is higher and increases with age.

has a great ability to form biofilms on implant-related biomaterials. This study aimed to investigate the resistance, biofilm and molecular characteristics of

strains isolated from patients with postoperative infections after arthroplasty in two Chinese tertiary care hospitals during 2017 to 2018.

Antimicrobial susceptibility was determined by the agar dilution method. Bevacizumab datasheet Bacterial biofilm formation was determined by crystal violet staining. The genes related to biofilm formation and molecular typing were analyzed by PCR amplification.

A total of 33 isolates were collected, 21 of which were from Henan. The strains were completely sensitive to vancomycin, linezolid, and nitrofurantoin. All the isolates had adhesion ability and could produce biofilms. Of the isolates, 75.0% from Chongqing and 85.7% from Henan had stronger biofilm formation abilities. The strains from Henan had slightly higher resistance, adhesion and biofilm-forming abilities than those from Chongqing. The strains in both hospitals carried at least two genes related to biofilm formation, and the

and

genes were the most frequently detected genes. Three SCC

types and seven sequence types (STs) were found in Henan, and two SCC

types and six STs were found in Chongqing. ST239-SCC

III was the main epidemic clone in the two hospitals.

The resistance phenotype and molecular characteristics of

strains varied in different hospitals. The results reflect the potential risks of

infection in postoperative arthroplasty patients. Our study provides a powerful basis for the clinical treatment, infection control and monitoring of outbreaks of epidemic strains.
