- Background: Peripheral artery disease is a growing public health problem. We aimed to estimate the global disease burden of peripheral artery disease, its risk factors, and temporospatial trends to inform policy and public measures.Methods: Data on peripheral artery disease were modelled using the Global Burden of Disease, Injuries, and Risk Factors Study (GBD) 2019 database. Prevalence, disability-adjusted life years (DALYs), and mortality estimates of peripheral artery disease were extracted from GBD 2019. Total DALYs and age-standardised DALY rate of peripheral artery disease attributed to modifiable risk factors were also assessed.Findings: In 2019, the number of people aged 40 years and older with peripheral artery disease was 113 million (95% uncertainty interval [UI] 99 center dot 2-128 center dot 4), with a global prevalence of 1 center dot 52% (95% UI 1 center dot 33-1 center dot 72), of which 42 center dot 6% was in countries with low to middle Socio-demographic Index (SDI). The global prevalence of peripheral artery disease was higher in older people, (14 center dot 91% [12 center dot 41-17 center dot 87] in those aged 80-84 years), and was generally higher in females than in males. Globally, the total number of DALYs attributable to modifiable risk factors in 2019 accounted for 69 center dot 4% (64 center dot 2-74 center dot 3) of total peripheral artery disease DALYs. The prevalence of peripheral artery disease was highest in countries with high SDI and lowest in countries with low SDI, whereas DALY and mortality rates showed U-shaped curves, with the highest burden in the high and low SDI quintiles.Interpretation: The total number of people with peripheral artery disease has increased globally from 1990 to 2019. Despite the lower prevalence of peripheral artery disease in males and low-income countries, these groups showed similar DALY rates to females and higher-income countries, highlighting disproportionate burden in these groups. Modifiable risk factors were responsible for around 70% of the global peripheral artery disease burden. Public measures could mitigate the burden of peripheral artery disease by modifying risk factors.

- Objective : Attitudes toward mental difficulties are influenced by culture, and different cultural backgrounds have different effects on people's behavior. This study aimed to prepare the Arabic version of the Peer Mental Health Stigmatization Scale (PMHSS) and validate it among Omani adolescents. Method : The study was conducted from October 2020 to the end of February 2021. The 24-items PMHSS was translated into Arabic and tested in a sample of 369 adolescents from different governmental schools in Oman. Both exploratory factor analysis (a principal component analysis (PCA) technique with Varimax rotation) and confirmatory factor analysis were performed to examine the construct validity of the PMHSS. Results : Confirmatory factor analysis was performed to examine the construct validity of the PMHSS. Cronbach’s α was 0.86 for the total scale and 0.84 and 0.81 for awareness and agreement, respectively. Therefore, the goodness-of fit-indicators support the two-correlated factor 16-item model to measure stigma (χ2 / df = 2.64 (p > 0.001), GFI = 0.92, AGFI = 0.89, CFI = 0.90, IFI = 0.90, RMSEA = 0.067). Conclusion : The Arabic version of the Peer Mental Health Stigmatization Scale (PMHSS) could assess adolescents’ stigmatizing attitudes toward various types of mental health problems within the Arabic context, and it can be utilized by researchers in Arab countries to screen for stigmatizing attitudes and to suggest suitable, effective, and outcome-focused interventions based on its results.

- New synthetic hybrid materials and their increasing complexity have placed growing demands on crystal growth for single-crystal X-ray diffraction analysis. Unfortunately, not all chemical systems are conducive to the isolation of single crystals for traditional characterization. Here, small-molecule serial femtosecond crystallography (smSFX) at atomic resolution (0.833 Å) is employed to characterize microcrystalline silver n-alkanethiolates with various alkyl chain lengths at X-ray free electron laser facilities, resolving long-standing controversies regarding the atomic connectivity and odd-even effects of layer stacking. smSFX provides high-quality crystal structures directly from the powder of the true unknowns, a capability that is particularly useful for systems having notoriously small or defective crystals. We present crystal structures of silver n-butanethiolate (C4), silver n-hexanethiolate (C6), and silver n-nonanethiolate (C9). We show that an odd-even effect originates from the orientation of the terminal methyl group and its role in packing efficiency. We also propose a secondary odd-even effect involving multiple mosaic blocks in the crystals containing even-numbered chains, identified by selected-area electron diffraction measurements. We conclude with a discussion of the merits of the synthetic preparation for the preparation of microdiffraction specimens and compare the long-range order in these crystals to that of self-assembled monolayers.
