The sympathetic effects of renal denervation and carotid baroreceptor stimulation as well as the possible involvement of sympathetic neural factors in the determination of the so-called "residual risk" of the treated hypertensive patients will be finally discussed.
Within the context of the wide use of fluoroquinolones (FQs) and the emergence of multidrug-resistant bacteria, French recommendations concerning the appropriate use of systemic FQs in adults were published in 2015. This study assessed the impact of antibiotic stewardship intervention on the use of FQs over a 5-year period.

Five annual audits were performed to evaluate FQ prescriptions. Following the baseline audit, a campaign of appropriate antibiotic use was initiated with courses on antibiotics including FQs. All audits included quantitative and qualitative evaluations to calculate an index of therapeutic adequacy (ITA) with six criteria indication, molecule type, dosage, duration, route of administration and association. These audits were performed annually from 2015 to 2019.

The number of prescriptions decreased substantially from 90 in 2015 to 17 in 2019. This reduction was consistent with consumption data, such that the defined daily dose for 1000 bed days diminished from 67 in 2015 to 42 in 2019. Between 2015 and 2016, the ITA decreased significantly from 3.27 to 1.79 (P = 0.001), corresponding to an improvement in prescription quality. The ITA stabilised between 2016 and 2019. Moreover, improvements were observed in the proportion of entirely conforming prescriptions, conformity of indications, choice of molecule type among FQs and proportion of prescriptions with non-conforming treatment durations.

Between 2015 and 2019, we observed quantitative and qualitative improvements in FQ prescriptions within the hospital. Prescription follow-up through annual audits, combined with training courses, contributed to consistent results.

Early combined antiretroviral therapy (cART) limits the total HIV-DNA load in children. However, data on its impact in older children and adolescents remain scarce. This study compares HIV reservoirs in children (5-12 years) and adolescents (13-17 years) who started cART <6 months (early [E-] group) or >2 years (late [L-] group).

The ANRS-EP59-CLEAC study prospectively enrolled 76 patients perinatally infected with HIV-1 who reached HIV-RNA <400 copies/mL <24 months after cART initiation, regardless of subsequent viral suppression (E-group 27 children, 9 adolescents; L-group 19 children, 21 adolescents). Total and integrated HIV-DNA were quantified in blood and in CD4+ T-cell subsets. A substudy assessed HIV reservoir inducibility after ex vivo peripheral blood mononuclear cell (PBMC) stimulation.

Total HIV-DNA levels were lower in early- versus late-treated patients (children 2.14 vs 2.87 log copies/million PBMCs; adolescents 2.25 vs 2.74 log; P < .0001 for both). Low reservoir was independently associated with treatment precocity, protective HLA, and low cumulative viremia since cART initiation. The 60 participants with undetectable integrated HIV-DNA started cART earlier than other patients (4 vs 54 months; P = .03). In those with sustained virological control, transitional and effector memory CD4+ T cells were less infected in the E-group than in the L-group (P = .03 and .02, respectively). Viral inducibility of reservoir cells after normalization to HIV-DNA levels was similar between groups.

Early cART results in a smaller blood HIV reservoir until adolescence, but all tested participants had an inducible reservoir. This deserves cautious consideration for HIV remission strategies.

Patient-based real-time quality control (PBRTQC) has gained increasing attention in the field of clinical laboratory management in recent years. Despite the many upsides that PBRTQC brings to the laboratory management system, it has been questioned for its performance and practical applicability for some analytes. This study introduces an extended method, regression-adjusted real-time quality control (RARTQC), to improve the performance of real-time quality control protocols.

In contrast to the PBRTQC, RARTQC has an additional regression adjustment step before using a common statistical process control algorithm, such as the moving average, to decide whether an analytical error exists. We used all patient test results of 4 analytes in 2019 from Zhongshan Hospital, Fudan University, to compare the performance of the 2 frameworks. Three types of analytical error were added in the study to compare the performance of PBRTQC and RARTQC protocols constant, random, and proportional errors. The false alarm rate and error detection charts were used to assess the protocols.

The study showed that RARTQC outperformed PBRTQC. RARTQC, compared with the PBRTQC, improved the trimmed average number of patients affected before detection (tANPed) at total allowable error by about 50% for both constant and proportional errors.

The regression step in the RARTQC framework removes autocorrelation in the test results, allows researchers to add additional variables, and improves data transformation. RARTQC is a powerful framework for real-time quality control research.

The utility of root hairs for nitrogen (N) acquisition is poorly understood.

We explored the utility of root hairs for N acquisition in the functional-structural model SimRoot and with maize genotypes with variable root hair length (RHL) in greenhouse and field environments.

Simulation results indicate that long, dense root hairs can improve N acquisition under varying N availability. In the greenhouse, ammonium availability had no effect on RHL and low nitrate availability increased RHL, while in the field low N reduced RHL. Longer RHL was associated with 216% increase in biomass and 237% increase in plant N content under low N conditions in the greenhouse and a 250% increase in biomass and 200% increase in plant N content in the field compared with short RHL phenotypes. In a low N field environment, genotypes with long RHL had 267% greater yield than those with short RHL. We speculate that long root hairs improve N capture by increased root surface area and expanded soil exploration beyond the N depletion zone surrounding the root surface.

We conclude that root hairs play an important role in nitrogen acquisition. We suggest that root hairs merit consideration as a breeding target for improved N acquisition in maize and other crops.

Patients presenting with more comorbidities, requiring more complex cardiac surgical procedures and an increase in public scrutiny are impacting on training programme because of the perceived risk of worse outcomes. Hence, we aimed to provide evidence that trainees as the first operator can achieve comparable results to consultants when performing isolated surgical aortic valve replacement.

From 1996 to 2017, 2919 patients underwent surgical aortic valve replacement at the Bristol Heart Institute, operated on by either a consultant (n = 2220) or a trainee (n = 870) as the first operator. Propensity score matching was used to adjust for imbalance in the baseline characteristics of the 2 groups.

Over a 21-year period, the proportion of trainee cases dropped from 41.5% to 25.9%. No differences in the rates and risk of in-hospital mortality, new cerebrovascular accidents, re-exploration for bleeding, deep sternal wound infection and length of stay were found between patients operated on in the 2 groups. Also, there was a comparable risk of late death between the 2 groups (HR 0.88; 95% CI 0.73-1.06; P = 0.27) and this was present regardless of trainees career level and patients surgical risk based on the EuroSCORE. Finally, we showed an increase in patients risk profile in the latest year but, this was not associated with the worst outcomes when trainees performed the operation.

Surgical aortic valve replacement is a safe and reproducible technique and regardless of the patient's risk profile, and no differences in the outcomes between trainees and consultant cases were found.

The duration of rectal gonococcal and chlamydial infection remains unknown. This basic epidemiologic parameter is needed to understand transmission dynamics.

We conducted a prospective, longitudinal, observational, cohort study of 140 men who have sex with men (MSM) at-risk of gonorrhea and chlamydia acquisition. For 48 weeks, enrolled men collected rectal swabs (Aptima multitest kit) at home and responded to an electronic survey about sexual behavior and health conditions weekly. Swabs remained untested until participants completed the study. We used Kaplan Meier estimates to determine the median duration of infection, censoring infections for treatment, loss-to-follow-up and end-of-study. We used Log-rank test to compare duration of infection by HIV status, history of infection with gonorrhea or chlamydia, and co-infection with the other pathogen.

140 enrolled MSM contributed 70.5 person years of follow-up. Eighteen men had 20 incident rectal gonococcal infections, which persisted for 2 - 23 weeks; 30% were censored for treatment. The estimated median duration of rectal gonorrhea was 9 weeks (95% CI 3-12 weeks). Twenty-four men experienced 32 rectal chlamydial infections, persisting between 2 to 42 weeks; 60% were censored. The estimated duration of rectal chlamydia was 13 weeks (95% CI 6 weeks - undefined). There were no differences in the duration of rectal gonorrhea or chlamydia by HIV status, history of chlamydia/gonorrhea or co-infection.

On average, rectal gonorrhea and chlamydial infections last 2-3 months, though some infections some persist for 6-11 months. Further understanding into predictors of persistence are needed.

The aim of this study was to evaluate the outcomes of open and endovascular treatment of downstream thoracic or thoraco-abdominal aortic pathology in patients who underwent previous frozen elephant trunk (FET).

Data were retrieved to evaluate mortality, cardiac, pulmonary, cerebrovascular, renal and spinal cord major adverse events, early- and mid-term reintervention and survival rates. The Society for Vascular Surgery endovascular reporting standards were used.

From 2011 to 2020, 48 patients (36 males, median age 60 years) underwent downstream aortic repair at a median of 18 months (interquartile range 6-57) after the initial FET. Twenty-eight patients (58.3%) received open and 20 (41.7%) endovascular repair. The overall 30-day mortality was 6.3% and the initial clinical success was 88%, with no inter-group differences (P = 0.22 and 0.66 respectively). Six spinal cord deficits were recorded (13%) 3 (6.3%) were permanent. find more The major adverse events incidence was lower in the endovascular cohort [4 (20%) vs 14 (50%); P = 0.
