For example, the prevalence of past-month HED was 30.0% (28.2, 31.8) among bisexual people versus 25.5% (23.8, 27.2) among lesbian/gay and 21.3% (19.6, 23.0) among heterosexual individuals. Pooled odds ratio estimates showed that bisexual people were more likely to report alcohol use and HED compared to their counterparts. Gender was a significant effect modifier in meta-regression analysis, with greater disparities among women than among men.

These results highlight the need for additional research to understand factors underlying bisexual people's greater risk, and particularly bisexual women, as well as alcohol use interventions that are targeted towards the specific needs of bisexual people.

A neural substrate of alcohol-related instability of gait and balance is the cerebellum. Whether disruption of neural communication between cerebellar and cortical brain regions exerts an influence on ataxia in alcohol use disorder (AUD) was the focus of this study.

Study groups comprised 32 abstinent AUD participants and 22 age- and sex-matched healthy controls (CTL). All participants underwent clinical screening, motor testing, and resting-state functional MR imaging analyzed for functional connectivity (FC) among 90 regions across the whole cerebrum and cerebellum. Ataxia testing quantified gait and balance with the Fregly-Graybiel Ataxia Battery conducted with and without vision.

The AUD group achieved lower scores than the CTL group on balance performance, which was disproportionately worse for eyes open than eyes closed in the AUD relative to the CTL group. Differences in ataxia were accompanied by differences in FC marked by cerebellar-frontal and cerebellar-parietal hyperconnectivity and corticoting to instability.

Quantitative results of SARS-CoV-2 testing reported as viral load copies/mL can provide valuable information, but are rarely used in practice. We analyze whether viral load in the upper respiratory tract is correlated with transmission and disease course and how this information can be used in practice.

Municipal Health Service (MHS) and clinical patients ≥18 years tested positive for SARS-CoV-2 with RT-PCR between June 1 and September 25, 2020 were included. Transmission was defined as an index having at least one contact tested positive. Test delay was defined as the time between symptom onset and SARS-CoV-2 testing.

683 patients were included (656 MHS and 27 clinical patients). The viral load was considerably lower among clinical patients compared to MHS patients median log

copies/mL 2.51 (IQR -1.52 - 6.46) vs 4.92 (IQR -0.54 - 8.26), p<0.0001. However, the test delay was higher for clinical patients (median 7 [IQR 2 - 19] vs 3 [IQR 0 - 26] days, p<0.0001). SARS-CoV-2 transmitters showed much higher viral loads than non-transmitters (log

copies/mL 5.23 [IQR -0.52 - 8.26] vs 4.65 [IQR -0.72 - 8.00], p<0.0001), but not for those with a test delay > 7 days. Higher viral loads were significantly correlated with older age and with more (severe) COVID-19 related symptoms.

Indexes that transmitted SARS-CoV-2 had more than three times higher viral loads than non-transmitters. Viral load information can be useful during source and contact tracing to prioritize indexes with highest risk of transmission, taking into account the test delay.

China is poised to become the world's second-largest oncology drug market. Its ability to continue broadening health coverage is in question. Institutional innovations such as performance-based risk-sharing agreements (PBRSAs) have been developed to promote access to novel therapeutics beyond that provided by public health insurance and central procurement systems. We examine in depth the financial implications of a PBRSA developed in China for the breast cancer drug palbociclib.

We generated a 2-state Markov model from PBRSA information made publicly available. Model inputs included breast cancer outcomes data from the published literature. The primary analysis estimates the percentage reduction in overall drug expenditures due to the PBRSA. Sensitivity analyses explored the financial impact of varied computed tomography scan utilization, rebate rate, and rebate duration.

Estimated palbociclib expenditures for the PBRSA cohort totaled $36 278 000. Based on the publicly available information for the PBRSA, an effective discount of 1.3% was estimated. The effective discount was insensitive to changes in computed tomography scan utilization.

The palbociclib PBRSA likely had negligible impact on patient access to therapy and limited downstream financial impact to patients and payers. The short duration of the rebate window, small rebate, and disease indolence contributed to the low expected rebate percentage.

Progressive AOS can present in isolation or co-occur with agrammatic aphasia and is associated with degeneration of the supplementary motor area. We aimed to assess breakdowns in structural connectivity from the supplementary motor area in patients with any combination of progressive AOS and/or agrammatic aphasia to determine which supplementary motor area tracts are specifically related to these clinical symptoms. Eighty-four patients with progressive AOS or progressive agrammatic aphasia were recruited by the Neurodegenerative Research Group and underwent neurological, speech/language, and neuropsychological testing, as well as 3 T diffusion magnetic resonance imaging. Of the 84 patients, 36 had apraxia of speech in isolation (primary progressive apraxia of speech, PPAOS), 40 had apraxia of speech and agrammatic aphasia (AOS-PAA), and eight had agrammatic aphasia in isoared to both other groups, with PAA showing greatest abnormalities furthest from the supplementary motor area. Severity of AOS correlated with tract metrics in the supplementary motor area commissural and motor cortex tracts. Severity of aphasia correlated with the frontal aslant and prefrontal tracts. These findings provide insight into how AOS and agrammatism are differentially related to disrupted diffusivity, with progressive AOS associated with abnormalities close to the supplementary motor area, and the frontal aslant and prefrontal tracts being particularly associated with agrammatic aphasia.

Episodic memory is the ability that enables individuals to recall and re-experience previous events and usually includes information concerning the spatial and temporal context. This study examined the effects of a physical exercise break during a period of prolonged sitting on episodic memory. Furthermore, we aimed to investigate whether alterations of functional connectivity patterns might contribute to the exercise-induced changes in episodic memory.

Sixty healthy male college students were randomly assigned (11 ratio) to a prolonged-sitting group (PS group) or a physical-exercise-break group (PE group). The face-name paired-associate learning task was used to probe episodic memory. During the task, cortical hemodynamics in the prefrontal cortex were recorded using functional near-infrared spectroscopy (fNIRS). Changes in cortical hemodynamics were used to determine functional connectivity using graph-theoretical network analysis.

There was no between-group difference in neurobehavioral outcomes at tpisodic memory. However, physical breaks do facilitate functional connectivity patterns of the prefrontal cortex while performing a episodic memory task.

Our findings suggest that a physical exercise break during a prolonged sitting period has neither a beneficial nor a detrimental effect on behavioral performance concerning episodic memory. However, physical breaks do facilitate functional connectivity patterns of the prefrontal cortex while performing a episodic memory task.Carbon-based materials activated peracetic acid (PAA) to repair groundwater is an environmentally friendly and low-cost technology to overcome secondary pollution problems. In this study, thermally modified activated carbon (AC600) was applied to activate PAA to degrade sulfamethoxazole (SMX). And the effect of groundwater pH, chloride ion (Cl-), bicarbonate (HCO3-), sulfate ion (SO42-), and natural organic matter (NOM) on SMX removal by AC600/PAA process was studied in detail. PAA could be effectively activated by AC600. Increasing AC600 dose (10-100mg/L) or PAA dosages (0.065-0.39 mM) generally enhanced the SMX removal, the excellent performance in SMX removal was achieved at 50 mg/L AC600 and 0.26 mM PAA. The removal of SMX was well-described by second-order kinetic, with the rate constant (kobs) of 10.79 M-1s-1, both much greater than the removal constants of PAA alone (0.034 M-1s-1) and AC600 alone (1.774 M-1s-1). R-O·(CH3C(O)OO·, CH3C(O)O·) and electron-transfer process were proved to be responsible for the removal of SMX while HO· and 1O2 made little to no contribution to the novel PAA/AC600 system, which differs from typical advanced oxidation processes. The SMX can be removed effectively over a wide pH range (3-9), exhibiting a remarkable pH-tolerant performance. Sulfate ion (SO42-), dissolved oxygen (DO), NOM displayed negligible influence on the SMX removal. Bicarbonate (HCO3-) exerted an inhibitory effect on SMX abatement, while chloride ion (Cl-) promoted the removal of SMX. This showed excellent anti-interference capacity and satisfactory decontamination performance under actual groundwater conditions. Furthermore, the degradation pathways of SMX were proposed, there was no obvious difference in the acute toxicity of the mixed products during the degradation process. It will facilitate further research of metal-free catalyst/PAA system as a new strategy for groundwater in-situ remediation technology.This work investigates the feasibility of using a nonlinear low-frequency Lamb wave approach for characterizing the interfacial property of a two-layered plate. Compared with the case of the exact phase-velocity matching, the approximate phase-velocity matching in the low-frequency region can still guarantee the cumulative second-harmonic generation (SHG) of primary Lamb wave propagation, which overcomes the drawbacks arising from the inherent dispersion and multimode features of Lamb wave propagation. For a given two-layered plate, the appropriate mode pair at low frequency consisting of primary Lamb wave and double-frequency Lamb wave (DFLW), which satisfies the approximate phase-velocity matching and nonzero energy flux, is selected to ensure that the amplitude of the generated second harmonic grows within the maximum cumulative distance (MCD). Meanwhile, the numerical analyses indicate that the variation of the SHG efficiency is maximized at the MCD during the interfacial degradation. Using the nonlinear ultrasonic measurement-based experimental setup, the time-domain signal of the second harmonic generated at different propagation distances is conveniently extracted, and then the relative nonlinear acoustic parameter curve consistent with the theoretical prediction is obtained.
