63, -0.89 to -0.36), with a significant decrease in total antioxidant capacity/status (-1.65, -2.88 to -0.43), aldehyde/NADPH dehydrogenase (-0.77, -1.38 to -0.17), lactoferrin/transferrin/albumin (-1.92, -2.96 to -0.89) and selenium/zinc (-1.42, -2.23 to -0.61). Oxidative stress markers were higher in tears and in cornea of keratoconus than in aqueous humour, and antioxidants were decreased in tears, aqueous humour and blood without difference between sample type. Heparan molecular weight Oxidative stress markers increased in stromal cells and antioxidants decreased in endothelium. Oxidative stress markers and antioxidants were dysregulated in keratoconus, involving an imbalance of redox homeostasis in tears, cornea, aqueous humour and blood.Oxidative stress markers and antioxidants were dysregulated in keratoconus, involving an imbalance of redox homeostasis in tears, cornea, aqueous humour and blood. The COVID-19 pandemic has introduced many mental health professionals to therapy via videoconferencing. Mostly individual teletherapy has been offered and studied, although group therapy is often offered in clinics. In fact, little is known regarding group therapy's acceptability, feasibility, and potential impact when offered via videoconferencing. This pilot study offered group cognitive-behavioural therapy for psychosis via videoconferencing to 14 individuals with early psychosis either living in remote areas or confined during the pandemic. The rate of consenting to the study (79%) and actual participation rates were acceptable (18.5 sessions out of 24). Although some technological obstacles were encountered, solutions offered allowed the videoconferencing group to be considered feasible for most participants and therapists. Prepost results on symptoms and self-esteem were comparable to those of other studies using the same group treatment but in-person. Alliance scores seemed similar as well. More studies are warranted on the efficacy of group therapy via videoconferencing. This pilot study does offer promising results, suggesting that a wider range of people with early psychosis can be reached and benefit from the advantages of receiving an evidence-based group intervention.More studies are warranted on the efficacy of group therapy via videoconferencing.

One particular trophic factor in the tissue environment is iron, which is intimately linked to macrophage effector functions. Macrophages have a well-described role in the control of systemic iron levels, but their activation state is also depending on iron-containing proteins/enzymes. Haemoproteins, dioxygenases and iron-sulphur (Fe-S) enzymes are iron-binding proteins that have bactericidal, metabolic and epigenetic-related functions, essential to shape the context-dependent macrophage polarization. In this review, I describe mainly pro-inflammatory macrophage polarization focussing on the role of iron biochemistry in selected haemoproteins and Fe-S enzymes. I show how iron, as part of haem or Fe-S clusters, participates in the cellular control of pro-inflammatory redox reactions in parallel with its role as enzymatic cofactor. I highlight a possible coordinated regulation of haemoproteins and Fe-S enzymes during classical macrophage activation. Finally, I describe tryptophan and α-ketoglutarate metabolism as two essential effector pathways in macrophages that use diverse iron biochemistry at different enzymatic steps. Through these pathways, I show how iron participates in the regulation of essential metabolites that shape macrophage function.Therapeutic options are urgently needed for non-alcoholic fatty liver disease (NAFLD), but development is time-consuming and costly. In contrast, drug repurposing offers the advantages of re-applying compounds that are already approved, thereby reducing cost. Acetylsalicylic acid (ASA) and pentoxifylline (PTX) have shown promise for treatment of NAFLD, but have not yet been tested in combination. Guinea pigs were fed a high-fat diet for 16 weeks and then continued on the diet while being treated with ASA, PTX or ASA+PTX for 8 weeks. Chow-fed animals served as healthy controls. Guinea pigs were CT scanned before intervention start and at intervention end. Animals without steatosis (ie NAFLD) at week 16 were excluded from the data analysis. ASA and PTX alone or in combination did not improve hepatic steatosis, ballooning, inflammation or fibrosis nor did the treatments affect liver enzymes (aminotransferases and alkaline phosphatase) or circulating lipids. Liver triglyceride levels, relative liver weight and hepatic mRNA expression of monocyte chemoattractant protein 1, interleukin 8 and platelet-derived growth factor b were nominally decreased. Thus, in the current study, treatment with ASA and PTX alone or in combination for 8 weeks did not ameliorate NASH or hepatic fibrosis in guinea pigs. To compare subfoveal choroidal thickness (SFCT) and associated clinical variables in patients with carotid stenosis (CS) before and 6months after carotid endarterectomy (CEA). The prospective non-randomized Helsinki Carotid Endarterectomy Study - Brain and Eye Sub-sTudy included seventy patients (81% male, mean age 69years) and 40 control subjects (77% male, 68years), from March 2015 to December 2018. Ophthalmological examination included SFCT measured with enhanced-depth imaging-optical coherence tomography. Carotid stenosis (CS) was more severe (≥70% stenosis in 92%) ipsilateral to the CEA than contralaterally (<50% stenosis in 74%; p<0.001). At baseline, patients had thinner mean SFCT than control subjects in both eyes (ipsilateral, 222 versus 257μm and contralateral, 217 versus 258μm, p≤0.005). At follow-up, SFCT did not change in ipsi- and contralateral eyes compared to baseline in patients (p=0.68 and p=0.77), or in control subjects (p=0.59 and p=0.79). Patients with coronary artery disease had thinner mean SFCT versus those without it in ipsilateral eyes before CEA (200 versus 233μm, p=0.
