Twenty-eight neurotrauma experts generated 675 research questions. Of these, 364 (53.9%) reached consensus, and 56 were determined to be high priority (15.4%), 303 were deemed to be medium priority (83.2%), and 5 were low priority (1.4%). The research topics were stratified into three groups-severe traumatic brain injury (TBI), mild TBI (mTBI), and spinal cord injury. The number of high-priority questions for each subtopic was 46 for severe TBI (19.7%), 3 for mTBI (4.3%) and 7 for SCI (11.7%).

This Delphi gap analysis of neurotrauma research identified 56 high-priority research questions. There are clear areas of focus for severe TBI, mTBI, and spinal cord injury that will help guide investigators in future neurotrauma research. Funding agencies should consider these gaps when they prioritize future research.

Diazepam is one of the most commonly prescribed tranquilizers for the therapy of alcohol withdrawal syndrome (AWS). However, diazepam therapy often turns out to be ineffective, and some patients experience dose-dependent adverse drug reactions. Previous studies have shown that the metabolism of diazepam involves the CYP2C19 isoenzyme, whose activity is highly dependent on polymorphism of the encoding gene.

The study aimed to investigate the effects of CYP2C19*17 genetic polymorphisms on plasma and saliva concentrations of diazepam as well as its impact on the efficacy and safety rates of therapy in patients with AWS.

The study was conducted on 100 Russian male patients suffering from the AWS who received diazepam injections at a dosage of 30.0 mg/day for 5 days. Genotyping was performed by real-time PCR with allele-specific hybridization. The efficacy and safety assessment was performed using psychometric scales.

Based on the results of the study, we revealed differences in the efficacy and safety of therapy in patients with different CYP2C19 -806C>T genotypes. Therapeutic drug monitoring revealed the statistically significant difference in the levels of diazepam plasma concentration (CC) 251.76 (214.43; 310.61) vs. (CT+TT) 89.74 (54.18; 179.13); P = 0.003, and diazepam saliva concentration (CC) 3.86 (3.22; 5.12) vs. (CT+TT) 0.79 (0.44; 1.56); P = 0.003.

Our study showed the effects of CYP2C19*17 genetic polymorphisms on the efficacy and safety rates of diazepam. Furthermore, we revealed the statistically significant differences in plasma and saliva concentration levels of diazepam in patients carrying different genotypes.

Network approaches can be used to study sociosexual partnerships and identify individuals at high risk of infection. Little is known about the cost structure of these services and their association with STD diagnoses.

We collected costs associated with using a peer network strategy to recruit men who have sex with men and transwomen of color in 4 counties in North Carolina Guilford, Forsyth, Durham, and Wake from February through October 2019. We used a comprehensive costing approach to gather detailed retrospective information on the intervention cost, broken down by category and programmatic activity.

The sociosexual networks collected consisted of 31 initial seeds (index cases) and 49 peers of those seeds. In peers, 5 cases of human immunodeficiency virus (HIV) and 10 cases of syphilis were identified. The cost per case (HIV or syphilis) identified was $7325. Personnel costs accounted for 80% of total expenditures, followed by laboratory expenses (12%). Personnel cost was distributed between disease intervention specialist patient navigators (51%), nonclinical (37%), and management (12%) staff. General administration was the costliest programmatic activity (37%), followed by case management and field services (37%), and study activities (11%). The estimated average cost per patient tested was $2242.

Finding positive peer cases in nonclinical settings is costly but may be crucial for limiting the spread of sexually transmitted diseases. The cost of staff was the major driver. This study demonstrates that using a network strategy can be a cost-effective way to identify, test, and refer patients at high risk of syphilis and HIV infections to care.

Reinfection and partner transmission are common with Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT). We assessed treatment and follow-up laboratory testing for GC and CT and evaluated associations with patient- and system-level factors.

The analysis included positive GC and/or CT nucleic acid amplification test results from patients aged 14 to 24 years at a federally qualified health center system site in Denver, CO, from January 2018 to December 2019. Outcomes assessed include treatment within 14 days, HIV/syphilis testing within 6 months, and repeat GC and CT testing within 2 to 6 months. Bivariate and multivariable regression modeling assessed associated factors.

Among 27,168 GC/CT nucleic acid amplification tests performed, 1.8% (484) were positive for GC and 7.8% (2125) were positive for CT. Within the assessed time frames, 87% (2275) of patients were treated, 54.1% (1411) had HIV testing, 50.1% (1306) had syphilis testing, and 39.9% (1040) had GC and CT retesting. Older patients were moent of these infections to decrease complications, reduce transmission, and combat the rising rates of sexually transmitted infections.

The uptake of preexposure prophylaxis (PrEP) against HIV is low among young men who have sex with men (MSM) in the Netherlands. Studying the intention to use PrEP among non-PrEP using young and older MSM can guide health authorities in developing new prevention campaigns to optimize PrEP uptake.

We investigated the sociodemographic, behavioral, and psychosocial factors associated with a high PrEP use intention in the coming 6 months among 93 young MSM (aged ≤25 years), participating in an online survey, and 290 older MSM (aged ≥26 years), participating in an open, prospective cohort in 2019 to 2020.

Perceiving PrEP as an important prevention tool was associated with a high PrEP use intention among young and older MSM. Among young MSM, a high level of PrEP knowledge and believing that PrEP users take good care of themselves and others were associated with a high PrEP use intention. Among older MSM, 2 or more anal sex partners, chemsex, high HIV risk perception, and believing PrEP increases sexual pleasure were associated with a high PrEP use intention. Believing PrEP leads to adverse effects was associated with a low intention to use PrEP among older MSM.

To conclude, we showed that both behavioral and psychosocial factors were associated with a high PrEP use intention among young and older MSM. In addition to focusing on sexual behavior and HIV risk, future prevention campaigns and counseling on PrEP could incorporate education, endorsing positive beliefs, and disarming negative beliefs to improve the uptake of PrEP in young and older MSM.

The recent detection of hepatitis C virus genotype 4 infection in human immunodeficiency virus-infected patients prompted performing molecular characterization of these isolates. All the Mexican isolates belonged to a subcluster within the 4d group and shared a common ancestor with a French isolate. The estimated timing of introduction in Mexico City was as recent as December 2015.

However, candidate endo-PGases for this purpose have rarely been reported. TEN-010 In this study, we expressed a gene from Penicillium oxalicum in Pichia pastoris. The recombinant enzyme PoxaEnPG28C had an optimal enzyme activity at pH 4.5 and 45°C and was stable at pH 3.0-6.5 and less then 45°C. The enzyme had a specific activity of 4,377.65 ± 55.37 U/mg towards polygalacturonic acid, and the Km and Vmax values of PoxaEnPG28C were calculated as 1.64 g/l and 6127.45 U/mg, respectively. PoxaEnPG28C increased the light transmittance of orange, lemon, strawberry and hawthorn juice by 13.9 ± 0.3%, 29.4 ± 3.8%, 95.7 ± 10.2% and 79.8 ± 1.7%, respectively; it reduced the viscosity of the same juices by 25.7 ± 1.6%, 52.0 ± 4.5%, 48.2 ± 0.7% and 80.5 ± 2.3%, respectively, and it increased the yield of the juices by 24.5 ± 0.7%, 12.7 ± 2.2%, 48.5 ± 4.2% and 104.5 ± 6.4%, respectively. Thus, PoxaEnPG28C could be considered an excellent candidate enzyme for acidic fruit juice production. Remarkably, fruit juice production using hawthorn as an material was reported for the first time.In this study we aimed to develop novel ZnO-NP/chitosan/β-glycerophosphate (ZnO-NP/CS/β-GP) antibacterial hydrogels for biomedical applications. According to the mass fraction ratio of ZnO-NPs to chitosan, mixtures of 1, 3, and 5% ZnO-NPs/CS/β-GP were prepared. Using the test-tube inversion method, scanning electron microscopy and Fourier-transform infrared spectroscopy, the influence of ZnO-NPs on gelation time, chemical composition, and cross-sectional microstructures were evaluated. Adding ZnO-NPs significantly improved the hydrogel's antibacterial activity as determined by bacteriostatic zone and colony counting. The hydrogel's bacteriostatic mechanism was investigated using live/dead fluorescent staining and scanning electron microscopy. In addition, crystal violet staining and MTT assay demonstrated that ZnO-NPs/CS/β-GP exhibited good antibacterial activity in inhibiting the formation of biofilms and eradicating existing biofilms. CCK-8 and live/dead cell staining methods revealed that the cell viability of gingival fibroblasts (L929) cocultured with hydrogel in each group was above 90% after 24, 48, and 72 h. These results suggest that ZnO-NPs improve the temperature sensitivity and bacteriostatic performance of chitosan/β-glycerophosphate (CS/β-GP), which could be injected into the periodontal pocket in solution form and quickly transformed into hydrogel adhesion on the gingiva, allowing for a straightforward and convenient procedure. In conclusion, ZnO-NP/CS/β-GP thermosensitive hydrogels could be expected to be utilized as adjuvant drugs for clinical prevention and treatment of peri-implant inflammation.
