old ones.Two nitrogen balance studies were conducted to evaluate the relative bioavailability values (RBV) of dl-methionine (dl-Met) and dl-methionine hydroxy analog calcium salt (MHA-Ca) to l-methionine (l-Met) as Met sources fed to pigs. In experiment 1, 42 pigs were assigned to 7 treatments feeding with basal diet (BD) formulated to be deficient in Met (0.22% standardized ileal digestible basis) but adequate in other amino acids. Diets included (1) BD, (2) BD + 0.025% dl-Met, (3) BD + 0.050% dl-Met, (4) BD + 0.075% dl-Met, (5) BD + 0.025% l-Met, (6) BD + 0.050% l-Met, and (7) BD + 0.075% l-Met. Increasing levels of l-Met and dl-Met enhanced N retained (g/d) and N retention (% of intake) linearly (P 0.05) on N retained (g/d) and N retention (% of intake). Using linear slope-ratio regression, the RBV of MHA-Ca compared with l-Met was 70% (95% confidence limits 59% to 81%) on a product-to-product basis or 83% on equimolar basis based on N retained expressed as g/d. Overall, the mean RBV of dl-Met to l-Met of 97% (95% confidence limits cover 100%) indicated that dl-Met and l-Met are equally bioavailable as Met sources in pigs. Gefitinib Compared with l-Met, the RBV of MHA-Ca was lower at 70% (95% confidence limits 59% to 81%) on a product-to-product basis or 83% on equimolar basis in starter pigs.
Reconstruction after endoscopic endonasal approaches is a key element. Lower clivus reconstruction is difficult and most of the times a pedicled flap is not available. As the complexity and the dimensions of the exposure increase, a reliable reconstruction technique becomes more and more important.
To describe the anatomic and technical nuances of the transposition of the temporoparietal fascial flap for lower clivus reconstruction.
A specific temporoparietal fascial flap (TPFF) design and tunneling technique has been studied using 4 head specimens, microscopic and endoscopic surgical techniques, and neuronavigation.
The L-shaped flap offers several advantages. It can be tunneled directly toward the lower clivus passing through the infratemporal fossa.
The infratemporal retro-eustachian transposition of an L-shaped TPFF provides a vascularized tissue virtually without dimension limits. This is the only technique that allows the flap to be tunneled directly in the lower clivus with the most vascular portion being at the bottom of the defect. Clinical validation is still required since more issues may become relevant in a real-surgery setting. Though, due to its possible complications, this methodology needs further testing and should not be attempted in less experienced hands.

Levofloxacin prophylaxis is recommended to prevent Gram-negative bloodstream infections (BSIs) in patients with prolonged chemotherapy-induced neutropenia. However, increasing fluoroquinolone resistance may decrease the effectiveness of this approach.
We assessed the prevalence of colonization with fluoroquinolone-resistant Enterobacterales (FQRE) among patients admitted for hematopoietic cell transplantation (HCT) from November 2016-August 2019 and compared the risk of Gram-negative BSI between FQRE-colonized and non-colonized patients. All patients received levofloxacin prophylaxis during neutropenia. Stool samples were collected upon admission for HCT and weekly thereafter until recovery from neutropenia, and underwent selective culture for FQRE. All isolates were identified and underwent antimicrobial susceptibility testing by broth microdilution. FQRE isolates also underwent whole-genome sequencing.
Fifty-four (23%) of 234 patients were colonized with FQRE prior to HCT, including 30 (25%) of 119 alwhile receiving levofloxacin prophylaxis and infections were typically caused by their colonizing strains. In contrast, levofloxacin prophylaxis was highly effective in patients not initially colonized with FQRE.Despite recent calls to integrate HIV testing into social services addressing intimate partner violence (IPV), few studies have reported on survivors' perspectives regarding the desired characteristics of this integration. The purpose of this study was to describe desired characteristics of HIV and sexually transmitted infection (STI) testing services from a survivor's perspective. A qualitative descriptive approach was taken to describe the perspectives of IPV survivors who may or may not have accessed this service. Four focus groups were conducted with a diverse sample of English and Spanish speakers (N = 25) who sought services through a family justice center and associated shelters. Focus groups were recorded, transcribed, and analyzed using conventional content analysis. Three themes were identified, including (1) peace of mind; (2) interacting stigmas and traumas; and (3) making testing easy, comfortable, and tailored. The findings of this study have the potential to influence survivor-centered practices and policies regarding the integration of culturally informed HIV/STI and IPV services.In the present study, we aimed to investigate the presence, seasonal distribution and biomolecular characterization of Vibrio parahaemolyticus and Vibrio vulnificus in samples of bivalve molluscs ( Mytilus galloprovincialis, Crassostrea gigas, Ruditapes decussatus, Venus verrucosa and Solen vagina ) and gastropod molluscs (Murex brandaris) harvested and marketed in Sardinia (Italy) between 2017 and 2018. A total of 444 samples were submitted to qualitative determination of Vibrio spp., V. parahaemolyticus and V. vulnificus. Identification and virulence profile of the isolated strains were performed by biomolecular methods. The overall prevalence of Vibrio spp. was 7%. The highest prevalence was pointed out in R. decussatus (8.3%). The prevalence of V. parahaemolyticus and V. vulnificus were 2.7% and 4.7% respectively. Higher levels of V. parahaemolyticus and V. vulnificus prevalence were highlighted in R. decussatus (4.2%) and C. gigas (6.2%) respectively. Potentially pathogenic V. parahaemolyticus strains were a minority ( n.Gefitinib
