Global, regional, and national incidence and mortality burden of non-COVID-19 lower respiratory infections and aetiologies, 1990–2021: a systematic analysis from the Global Burden... by Bender, RG, Sirota, SB, Swetschinski, LR, Berkley, JA, Eyre, DW, McManigal, B, Pollard, AJ, Roberts, T, Runghien, T, Sartorius, B

“…For aetiology estimation, we analysed multiple causes of death, vital registration, hospital discharge, microbial laboratory, and literature data using a network analysis model to produce the proportion of LRI deaths and episodes attributable to the following pathogens: Acinetobacter baumannii, Chlamydia spp, Enterobacter spp, Escherichia coli, fungi, group B streptococcus, Haemophilus influenzae, influenza viruses, Klebsiella pneumoniae, Legionella spp, Mycoplasma spp, polymicrobial infections, Pseudomonas aeruginosa, respiratory syncytial virus (RSV), Staphylococcus aureus, Streptococcus pneumoniae, and other viruses (ie, the aggregate of all viruses studied except influenza and RSV), as well as a residual category of other bacterial pathogens. <p><b>Findings</b></p> Globally, in 2021, we estimated 344 million (95% uncertainty interval [UI] 325–364) incident episodes of LRI, or 4350 episodes (4120–4610) per 100 000 population, and 2·18 million deaths (1·98–2·36), or 27·7 deaths (25·1–29·9) per 100 000. 502 000 deaths (406 000–611 000) were in children younger than 5 years, among which 254 000 deaths (197 000–320 000) occurred in countries with a low Socio-demographic Index. …”

Amino-functionalised β-diketiminate ligands (N-nacnacs): Synthesis and coordination chemistry with Main Group elements by Huan, D

“…This is broadly in line with the experimental findings, with the exception of the R = P(SiMe₃)₂ system which, together with the σ-withdrawing R = Cl system, exists in the N-nacnac-chelate form at room temperature.…”

Genetic and observational associations of nuclear magnetic resonance-measured lipid-related traits and atherosclerotic cardiovascular mortality in the Mexico City Prospective Study by Wang, Y

“…Further MR analyses supported that only ApoB was independently and significantly related to an increased risk of ASCVD mortality in a multivariable setting and suggested ApoB, as the accurate measure of apoB particles, is causally related to the risk of ASCVD, independent of lipid contents such as TG and cholesterol, and HDL or ApoA1. MR findings did not support TG as a causal factor in the development of ASCVD.…”

Molecular and immunological profiling of Bartonella spp. in shelter cat population in Peninsular Malaysia by Alias, Nurul Najwa Ainaa
