Abstract	The synthesis, photophysical properties, and applications of highly fluorescent and phosphorescent palladium complexes are reviewed, covering the period 2018-2022. Despite the fact that the Pd atom appears closely related with an efficient quenching of the fluorescence of different molecules, different synthetic strategies have been recently optimized to achieve the preservation and even the amplification of the luminescent properties of several fluorophores after Pd incorporation. Beyond classical methodologies such as orthopalladation or the use of highly emissive ligands as porphyrins and related systems (for instance, biladiene), new concepts such as AIE (Aggregation Induced Emission) in metallacages or in coordination-driven supramolecular compounds (CDS) by restriction of intramolecular motions (RIM), or complexes showing TADF (Thermally Activated Delayed Fluorescence), are here described and analysed. Without pretending to be comprehensive, selected examples of applications in areas such as the fabrication of lighting devices, biological markers, photodynamic therapy, or oxygen sensing are also here reported.

Article: Reactivity of (Z)-4-Aryliden-5(4H)-thiazolones: [2 + 2]-Photocycloaddition, Ring-Opening Reactions, and Influence of the Lewis Acid BF₃

Abstract	The irradiation of (Z)-2-phenyl-4-aryliden-5(4H)-thiazolones 2 with blue light (465 nm) in CH₂Cl₂ solution promotes [2 + 2]-photocycloaddition of the exocyclic C═C bonds and the formation of the dispirocyclobutanes 3. This reaction takes place with high stereoselectivity, given that the ε-isomer (1,3 head-to-tail syn coupling) is formed in more than 90% yield in most of the cases. However, irradiation of 5(4H)-thiazolones 2 with blue light (456 nm) in dry MeOH in the presence of BF₃·OEt₂ leads to the monospirocyclobutanes 4 with full stereoselectivity, also affording the ε-isomer. A ring-opening reaction of only one of the thiazolone rings appears to have taken place in 4 upon methanolysis, leading to the corresponding ester and thioamide groups. The treatment of free 4-aryliden-5(4H)-thiazolones 2 with a base in alcohol (NaOR/ROH) also produces a ring-opening reaction of the heterocycle by methanolysis, although, under these reaction conditions, further intramolecular S-attack at the exocyclic C(H)═C bond and cyclization is observed, forming the dihydrothiazoles 5 or 6 as mixtures of cis (RS/SR)- and trans (RR/SS)-isomers with high diastereomeric excess. trans-(RR/SS)-Dihydrothiazoles 6 can be isolated as pure diastereoisomers by column chromatography. Surprisingly, dihydrothiazoles 5 can also be obtained by the treatment of 4-aryliden-5(4H)-thiazolones 2 with BF₃·OEt₂ in methanol in the absence of a base.

Abstract	Objective: To estimate life expectancy of people with HIV (PWH) and describe causes of death. Design: Antiretroviral therapy (ART)-naive adults from the CoRIS cohort starting ART in 2004-2019. Methods: We calculated life expectancy at age 40 for men and women according to their ART initiation period, and stratified by transmission category, CD4 + cell count and AIDS diagnosis. We estimated life expectancy in 10-year age bands using life tables constructed from mortality rates, estimated through Poisson models. Results: Life expectancy increased from 65.8 [95% confidence interval (CI) 65.0-66.6] in 2004-2008 to 72.9 (72.2-73.7) in 2014-2019 in men [general population comparators (GPC): 79.1 and 81.2 years, respectively] and from 65.8 (65.0-66.6) to 72.5 (71.8-73.3) in women (GPC: 84.9 and 86.4, respectively). Non-AIDS-related deaths accounted for 68% of deaths among men and 78% among women. Life expectancy was longer when starting ART with higher CD4 + cell counts and without AIDS. For men acquiring HIV through sex with men, starting ART in 2014-2019 without AIDS, life expectancy was 75.0 (74.2-75.7) with CD4 + cell count less than 200 cells/μl, rising to 78.1 (77.5-78.8) with CD4 + cell count at least 350 cells/μl. Corresponding figures were 70.1 (69.4-70.9) and 76.0 (75.3-76.7) for men acquiring HIV heterosexually (HTX) and 61.5 (60.7-62.3) and 69.0 (68.2-69.8) for those acquiring HIV through injection drug use (IDU). For women starting ART from 2014 without AIDS, life expectancy increased from 71.7 (71.0-72.4) to 77.3 (76.7-77.9) among HTX and from 63.7 (62.9-64.5) to 70.7 (70.0-71.5) among IDU. Conclusion: Our findings confirm the progressive improvement of life expectancy in PWH in Spain over the last decades, supporting the insurability of PWH on suppressive ART in our current setting and time.

Abstract	Objectives: People with HIV (PWH) have a higher cardiovascular risk than the general population. It remains unclear, however, whether the risk of cardiovascular disease (CVD) is higher in late HIV presenters (LP; CD4 ≤ 350 cells/μL at HIV diagnosis) compared to PWH diagnosed early. We aimed to assess the rates of incident cardiovascular events (CVEs) following ART initiation among LP compared to non-LP. Methods: From the prospective, multicentre PISCIS cohort, we included all adult people with HIV (PWH) initiating antiretroviral therapy (ART) between 2005 and 2019 without prior CVE. Additional data were extracted from public health registries. The primary outcome was the incidence of first CVE (ischemic heart disease, congestive heart failure, cerebrovascular, or peripheral vascular disease). The secondary outcome was all-cause mortality after the first CVE. We used Poisson regression. Results: We included 3,317 PWH [26 589.1 person/years (PY)]: 1761 LP and 1556 non-LP. Overall, 163 (4.9%) experienced a CVE [IR 6.1/1000PY (95%CI: 5.3-7.1)]: 105 (6.0%) LP vs. 58 (3.7%) non-LP. No differences were observed in the multivariate analysis adjusting for age, transmission mode, comorbidities, and calendar time, regardless of CD4 at ART initiation [aIRR 0.92 (0.62-1.36) and 0.84 (0.56-1.26) in LP with CD4 count <200 and 200- ≤ 350 cells/μL, respectively, compared to non-LP]. Overall mortality was 8.5% in LP Conclusion: CVD remains a common cause of morbidity and mortality among PWH. LP without prior CVD did not exhibit an increased long-term risk of CVE compared with non-LP. Identifying traditional cardiovascular risk factors is essential for CVD risk reduction in this population.

Abstract	Background: We studied the association of obesity-related single-nucleotide polymorphisms (OR-SNPs) with weight gain after antiretroviral therapy (ART) in people with human immunodeficiency virus (HIV; PWH). Methods: Participants were ART-naive PWH from the Spanish HIV Research Cohort who started ART from 2014 onward and had blood/DNA deposited in the cohort Biobank. The primary outcome was change in weight at 96 weeks after starting ART. We genotyped 14 OR-SNPs from a meta-analysis of genome-wide association studies of body mass index (BMI) loci. Changes over time in weight and BMI were studied using adjusted linear mixed models. Results: A total of 1021 PWH were included. The mean weight gain over 96 weeks was 2.90 (95% confidence interval, 2.54-3.26) kg. Factors associated with higher weight gain were female sex, birth in sub-Saharan Africa, prior AIDS, CD4+ <200 cells/µL, HIV-RNA >100 000 copies/mL, negative hepatitis C virus serology, and use of tenofovir alafenamide. A significant association was found between ZC3H4 rs3810291 GG genotype and BCDIN3D/FAIM2 rs7138803 GG genotype polymorphisms and weight and BMI increase. The estimated adjusted mean (standard error [SE]) of weight gain was 4.26 (0.56) kg in ZC3H4 rs3810291 GG carriers and 2.66 (0.19) kg in AA/AG carriers (P = .007). Likewise the estimated weight gain at 96 weeks was 3.35 (0.29) kg in BCDIN3D/FAIM2 rs7138803 GG carriers and 2.51 (0.24) kg in AG/AA carriers (P = .020). Conclusions: Genetic factors may play a role in weight gain after ART initiation. Further work is needed to replicate our findings and understand how the identified SNPs lead to higher weight gain in this context.
