To investigate cognitive changes after carotid revascularization in elderly patients with asymptomatic carotid artery stenosis. We also compared cognitive outcomes of carotid endarterectomy CEA with stenting in asymptomatic patients.

From April 2019 to December 2019, patients with ≥70% asymptomatic carotid stenosis who were treated with CEA or CAS, were recruited for this study. The Montreal cognitive assessment (MoCA) instrument was used to evaluate cognitive function preoperatively and postoperatively at 3, 6, and 12months. The incidence of ipsilateral ischemic cerebrovascular events and restenosis were analyzed within 12months.

In 50 patients treated with CEA or carotid artery stenting CAS, baseline cognitive function was not different between CEA and CAS groups (P>0.05). There was no difference in the incidence of ipsilateral ischemic cerebrovascular events and restenosis within the first 12months between the two groups. There was a significant improvement in the total MoCA score, scores of attention, and delayed recall at 3, 6 and 12months after revascularization compared with scores at baseline (all P<0.001). At 12months, scores of cube copying and clock drawing were significantly improved (P=0.014, P=0.020). The clock drawing score was improved at 12months after CAS compared with CEA (P=0.040).

Carotid revascularization has a beneficial effect on cognition in asymptomatic patients within 12months of the procedure. Compared with CEA, CAS show improved test scores of executive functioning by 1year.

Development of vaccines with high efficacy against COVID-19 disease has ushered a new ray of hope in the fight against the pandemic. Thromboembolic events have been reported after administration of vaccines. We aim to systematically review thromboembolic events reported after COVID-19 vaccination.

The available literature was systematically screened for available data on thromboembolic events after COVID-19 vaccination. Data were extracted from selected studies and analyzed for site of thromboembolism as well as other risk factors. All data were pooled to determine cumulative incidence of thromboembolism at various sites after vaccination.

A total of 20 studies were selected for the final analysis. The mean age of the population was 48.5±15.4years (females - 67.4%). The mean time to event after vaccination was 10.8±7.2days. Venous thrombosis (74.8%, n=214/286) was more common than arterial thrombosis (27.9%, n=80/286). Cerebral sinus thrombosis was the most common manifestation (28.3%, n=81/286) of venous thrombosis followed by deep vein thrombosis (19.2%, n=49/254). Myocardial infarction was common (20.1%, n=55/274) in patients with arterial thrombosis followed by ischemic stroke (8.02%, n=22/274). Concurrent thrombosis at multiple sites was noted in 15.4% patients. Majority of patients had thrombocytopenia (49%) and antiplatelet factor 4 antibodies (78.6%). Thromboembolic events were mostly reported after the AstraZeneca vaccine (93.7%). Cerebral sinus thrombosis was the most common among thromboembolic events reported after the AstraZeneca vaccine. Among the reported cases, mortality was noted in 29.9% patients.

Thromboembolic events can occur after COVID-19 vaccination, most commonly after the AstraZeneca vaccine. Cerebral sinus thrombosis is the most common manifestation noted in vaccinated individuals.

However, the appearance of some effector CD4+ T cell populations displaying cytotoxic activity, in particular during viral infections, has been observed, thus breaking the functional dichotomy of CD4+ and CD8+ T lymphocytes. The strong association of the appearance of CD4+ cytotoxic T lymphocytes (CD4 CTLs) with viral infections suggests an important role of this subset in antiviral immunity by controlling viral replication and infection. Moreover, CD4 CTLs have been linked with anti-tumor activity and might also cause immunopathology in autoimmune diseases. This raises interest into the molecular mechanisms regulating CD4 CTL differentiation, which are poorly understood in comparison to differentiation pathways of other Th subsets. In this review, we provide a brief overview about key features of CD4 CTLs, including their role in viral infections and cancer immunity, and about the link between CD4 CTLs and immune-mediated diseases. Subsequently, we will discuss the current knowledge about transcriptional and epigenetic networks controlling CD4 CTL differentiation and highlight recent data suggesting a role for histone deacetylases in the generation of CD4 CTLs.Follicular helper T (TFH) cells are expanded in systemic lupus erythematosus (SLE), where they are required for production of high affinity autoantibodies. A better understanding of the mechanisms that regulate the differentiation of TFH cells is critical. Naïve T cells from lupus-prone B6.NZM2410.Sle1.Sle2.Sle3 (TC) mice showed an intrinsic higher capacity to differentiate into TFH cells. Metabolic reprogramming is a vital regulatory mechanism for T cell differentiation, but how metabolic pathways contribute to TFH cell expansion in SLE remains elusive. Here we show that glycolysis, mTOR signaling, FAO, and the activity of complex V of the electron transport chain support TFH lineage commitment. Blocking complex I uniquely decreased the expansion of TFH cells from lupus-prone mice, and inhibition of some pathways had a greater effect in lupus-prone than control TFH cells. However, blocking glutaminolysis, complex III and ADP/ATP translocase did not affect TFH cell expansion. Together, our results identified novel intrinsic metabolic requirements for TFH cell differentiation, and further defined the differential metabolic pathways that support the expansion of TFH cells in lupus-prone mice. Together, our data indicates the crucial but distinct roles for metabolic pathways in TFH cell differentiation and provide a comprehensive experimental basis for fully understanding the precise roles of distant metabolic signaling in regulating the TFH cell differentiation.
Frailty is associated with long-term physical deterioration after COVID-19. Mental health recovery has been less well investigated. Early studies have shown minimal effect from the virus, although studies have not focused on whether people living with frailty may have different psychiatric outcomes. We aimed to examine the effect of living with frailty on mental health outcomes one year after hospital with COVID-19.

We undertook a multicentre cross-sectional study of people admitted with COVID-19. We assessed quality of life (ICECAP-O and MRC), psychiatric symptoms including generalised anxiety (GAD-7), depression (Patient Health Questionnaire-9), and trauma (Trauma Screening Questionnaire). Frailty was measured using the Clinical Frailty Scale (CFS). We used a multivariable mixed-effects logistic and linear regression to examine the adjusted odds ratio (aOR) and adjusted mean difference (aMD).

From eight hospitals 224 participants consented. Median follow-up time from admission 358days (IQR 153-418), mean age 63.8 (SD=13.7), 34.8% female (n=78), and 43.7% living with frailty (n=98 CFS 4-8). Dactolisib People living with frailty were significantly more likely to have symptoms of anxiety aOR=5.72 (95% CI 1.71-19.13), depression aOR=2.52 (95% CI 1.59-14.91), post-traumatic stress disorder aMD=1.16 (95% CI 0.47, 1.85), and worse quality of life aMD=1.06 (95% CI 0.76-1.36).

Patient-rated symptoms were captured rather than formal mental health diagnoses. CFS has not been validated in under 65-year-olds.

Living with frailty is associated with significant psychiatric morbidity and reduced wellbeing one year after COVID-19 hospital admission. We recommend clinical follow-up after COVID-19 for people living with frailty should include a psychiatric assessment.

Puerarin has been shown to have a good antidepressant effect, and our previous study found that it can remedy stress-induced dysbiosis. However, its gut microbiota-related mechanism has not been fully elucidated. Therefore, this study aimed to investigate the potential link between puerarin on gut microbiota and inflammatory responses in depressed rats.

A chronic unpredictable mild stress (CUMS) rat model of depression was established, open field test (OFT), sucrose preference test (SPT) and forced swimming test (FST) were used to evaluate its antidepressant effect. 16S rRNA sequencing was performed to identify the rat fecal microflora. At the same time, inflammatory cytokines, colonic histopathological changes, and brain-derived neurotrophic factor (BDNF), nuclear factor kappa-B (NF-κB), inhibitor a of NF-κB (IκB-α) protein expression were detected.

Puerarin attenuated CUMS-induced depressive-like behavior and gut microbiota dysregulation in rats, significantly reducing the abundance of harmful bacteria such as Desulfovibrio, Verrucomicrobiae, and Verrucomicrobia. In addition, puerarin can also reduce the pro-inflammatory factors and increase the level of anti-inflammatory factors in depressed rats, improve the damaged colon tissue, enhance the expression of BDNF and IκB-α in the hippocampus and inhibit the expression of NF-κB.

Direct evidence that puerarin improves depressive-like behaviors via gut microbiota is lacking.

The underlying mechanism of puerarin's antidepressant-like effect is closely related to the bidirectional communication of the microbiota-gut-brain axis by regulating the inflammatory response.

The health crisis caused by the COVID-19 pandemic has led to a considerable increase in the psychopathology of COVID-19 patients and among the general population. This study aims to conduct the psychometric analysis of the scale of concern about COVID-19 in the Spanish population and to estimate the level of concern and dysfunctional anxiety present one year after the lockdown measures in Spain aimed at resisting the spread of the viral disease among the population.

The factorial structure of the instrument, its reliability for the general population and for COVID patients, and its construct validity have been analyzed, and measurements of dysfunctional concern have been obtained from a sample of 502 adults.

The scale of concern about COVID-19 showed optimal results of reliability and validity for the Spanish population, confirming that it is an ideal instrument for estimating the concern regarding coronavirus contagion.

This study used a cross-sectional design and thus, could not compare the changes in the incidence of anxiety symptoms before and after the COVID-19 outbreak.
