Treatment delays in muscle invasive bladder cancer (MIBC) have been shown to be associated with worse outcomes. While every attempt is made to provide adequate treatment expeditiously, Black and Hispanic patients often experience delays at a higher rate than their White counterparts. This study aims to quantify the mechanisms that contribute to this disparity in treatment delay.

Retrospective analysis of clinical T-stages II-IVa MIBC patients who underwent surgical resection from 2004 to 2017 in the National Cancer Database. A causal inference mediation analysis using the counterfactual framework was implemented to estimate the extent to which racial/ethnic disparities in patient and system factors explain the racial/ethnic disparities in time to treatment. Mediators included income, education, comorbidities, insurance, and hospital type.

Among 22,864 patients who met inclusion criteria, 7%, 3%, 2% were of Black, Hispanic, and Other race/ethnicity, respectively. In multivariable models, compared to Whitclinical settings.

Black and Hispanic MIBC patients experience treatment delays when compared to White patients. Intervening upon patient and system factors could reduce substantial treatment delays. Future research is needed to identify other causes of disparities in treatment delays and may help population health initiatives to address racial/ethnic disparities in clinical settings.

The characteristics of recent National Institutes of Health (NIH) grant funding to anesthesiology researchers in United States (US) medical schools have not been systematically quantified. NIH funding to cardiac anesthesiologists has also not been estimated. The author conducted an internet-based analysis of NIH awards to anesthesiology researchers from 2011-2020 to identify the types, duration of funding, and amount of grants, and the terminal degree(s), faculty rank, gender, board certification status, and type of appointment of the grant recipients including those with an interest in cardiac anesthesiology.

Internet analysis.

NIH grants recipients.

None.

NIH grant recipients affiliated with anesthesiology departments were identified from the Blue Ridge Institute for Medical Research website. The number of grants, years of support, and total amount of funding were quantified for research project grants (R series), mentored career development awards (K series), and other gran of physician-scientists in anesthesiology.

PhDs, Professors, and male researchers receive the majority of R01 and other R series grants to anesthesiology departments at US medical schools. Physician-scientists, including those interested in cardiac anesthesiology, are awarded a minority of R series grants. FAER continues to provide an important stimulus for subsequent NIH funding of physician-scientists in anesthesiology.

To quantify dental forces during double-lumen tube intubations with different laryngoscopy techniques.

Experimental biomechanical mannequin study.

Two German university hospitals.

One hundred four anesthesiologists with varying levels of experience.

Participants performed a sequence of intubations on a mannequin equipped with hidden forces sensors in the maxillary incisors. Different laryngoscopy techniques were evaluated under normal and difficult airway conditions. Direct laryngoscopy was compared with different videolaryngoscopy techniques the C-MAC with a Macintosh blade, the GlideScope, and the KingVision with hyperangulated blades.

A total of 624 intubations were evaluated. In normal airway conditions, the median (interquartile range [range]) peak forces were significantly lower when the GlideScope (15.7 (11.3-22.0 [2.1-110.5]) N) was used compared with direct laryngoscopy (21.0 (14.1-28.5[4.7-168.6]) N) (p=0.007). In difficult airways, resulting forces were reduced using hyperangulated videolaryngoscopes (GlideScope -13.7 N [p < 0.001]; KingVision -11.9 N [p < 0.001]) compared with direct laryngoscopy, respectively. The time to intubation was prolonged with the use of the KingVision (25.5 (17.1-41.9[9.2-275.0])s [p < 0.001]) in comparison to direct laryngoscopy (20.8 (15.9-27.4[8.7-198.6]) s). The C-MAC demonstrated the shortest time to intubation.

Although hyperangulated videolaryngoscopes improve dental strain, clinicians also should consider the time to intubation, which is shortest with nonhyperangulated videoblades, when choosing a laryngoscopy technique on an individual patient basis.

The phytochemical allicin, found in garlic extract is a commendable antimicrobial agent that can be used in synergistic combination with modern antibiotics. Determination of optimal antibacterial combination for the target species is vital for maximizing efficacy, lowering toxicity, total eradication of the bacterial cells and minimization of the risk of resistance generation. In this present investigation, Hill function-based pharmacodynamics models were employed to elaborate various time-kill kinetics parameters. The bactericidal potency of the synergistic combinations of allicin and individual antibiotic was assessed in comparison to their monotherapy application viz. using sole allicin and sole antibiotics (levofloxacin, ciprofloxacin, oxytetracycline, rifaximin, ornidazole and azithromycin) on actively growing Bacillus subtilis and Escherichia coli bacteria. Here, all the synergistic combinations showed significantly better (t-test p-value less then 0.05) killing effect and biofilm reduction potential compared to their respective monotherapy application, where the highest killing effect was observed with rifaximin-allicin combination (kill rate was more than 5.5 h-1). Moreover, the average inhibition potential to protein denaturation by the synergistic combination group was significantly higher (3.4 fold) than the sole antibiotic's group manifests reduction in the dose-related toxicity. The potential of synergism between antibiotics and allicin combination demonstrated greater killing efficiency at significantly lower concentration compared to monotherapy with increased kill rates in all cases.Tissue-specific extracellular matrix (ECM) plays a critical role in cell survival and homeostasis, which are particularly essential for directing differentiation of different complex tissues such as retina. However, ECM maintenance should be considered to design an effective therapeutic strategy for retina regeneration. To achieve this, cell sheet engineering has emerged as a growing approach to closely reconstruct basal membrane of cells through a scaffold-free manner. Several irreversible sight-threatening diseases are characterized by the dysfunction and lose of retinal pigment epithelium (RPE), leading to vision loss and eventually total blindness in patients. According to impressive developments in achievement of RPE from human embryonic stem cells (hESCs), we obtained RPE cells without any extrinsic factors in a co-culture system, and cultured them on a temporary alginate hydrogel substrate. Subsequently, Arg-Gly-Asp (RGD) peptide was superficially immobilized on the upper layer of hydrogel to improve cell attachment before harvesting sheet layer. RPE cell sheet layer was released by treating pre-seeded hydrogels with sodium citrate as a calcium chelating agent and characterized in both in vitro and in vivo models. RPE sheets formed tight junction and expressed high levels of retina structural markers such as ZO-1, Bestrophin and Collagen type IV. One week after in vivo transplantation of RPE sheet, cells survived in the subretinal space, indicating that our harvesting method is non-invasive. To sum up, we introduced a unique scaffold-free method for RPE cell sheet engineering, which can find potential use for future therapeutic purposes.

We aimed to examine the effects of multisite anodal transcranial direct current stimulation (tDCS) combined with cognitive stimulation (CS) over 2 months on cognitive performance and brain activity, and the relationship between them, in patients with Alzheimer's disease (AD).

Patients with AD were randomly assigned to an active tDCS+CS (n=18) or a sham tDCS+CS (n=18) group. Cognitive performance was assessed using the Alzheimer Disease Assessment Scale-cognitive subscale (ADAS-cog) and brain activity using EEG (spectral power and coherence analysis) before and after the intervention. Multisite anodal tDCS (2 mA, 30 min) was applied over six brain regions [left and right dorsolateral prefrontal cortex (F3 and F4), Broca's area (F5), Wernicke's area (CP5), left and right somatosensory association cortex (P3 and P4)] for 24 sessions (three times a week). Both groups performed CS during tDCS.

Anodal tDCS+CS delays cognitive decline (ADAS-cog change) to a greater extent than sham tDCS+CS (-3.4±1.1 vs. -1.7±0s with AD.

We conducted an open-label cross-over study assessing the global effect of two high-frequency protocols of electric-field navigated repetitive transcranial magnetic stimulation (rTMS) targeted to functional facial motor cortex and comparing their efficacy and tolerability in patients with chronic facial pain. Outcome predictors were also assessed.

We randomized twenty consecutive patients with chronic facial pain (post-traumatic trigeminal neuropathic pain, n=14; persistent idiopathic facial pain, n=4; secondary trigeminal neuralgia, n=2) to receive two distinct 5-day rTMS interventions (10Hz, 2400 pulses and 20Hz, 3600 pulses) separated by six weeks. The target area was assessed by mapping of lower face representation. The primary endpoint was the change in weekly mean of pain intensity (numeric rating scale, NRS) between the baseline and therapy week (1

week), and follow-up weeks (2

and 3

weeks) for each rTMS intervention. Response was defined using a combination scale including the patient's globove 2400 pulses/session) did not improve the outcome. The results support early consideration of rTMS.

High-frequency rTMS targeted to face M1 alleviates treatment resistant chronic facial pain. Repeated treatment improves the analgesic effect. A protocol with higher frequency (above 10Hz), longer session duration (more than 20 minutes) and higher number of pulses (above 2400 pulses/session) did not improve the outcome. The results support early consideration of rTMS.

Iron deficiency is common in patients with end-stage renal disease (ESRD). SNX-5422 Platelet count changes may reflect iron status, but the relationship between platelet count and iron indices is unclear in patients with ESRD.

We conducted a retrospective study in 1,167 patients with ESRD from 2012 to 2017 in West China Hospital. Baseline data were used to analyze the relationship between the platelet count and iron indices. Patients were followed up for 3years.

Patients with iron deficiency (both absolute and functional) had a higher platelet count than those without iron deficiency (174±61×10

/L vs. 153±58×10

/L, P<.001). Receiver operating characteristic analysis showed a weak predictive power of platelet count on absolute iron deficiency (area under curve 0.620; cutoff value>137×10

/L, sensitivity 76%, specificity 43%) and functional iron deficiency (area under curve 0.540; cutoff value>124×10

/L, sensitivity 77%, specificity 32%). Platelet count was negatively correlated with ferritin (Spearman's rho [ρ] -0.
