Global economic burden of depression in 154 countries from 2025 to 2050.

July 28, 2026| Source: Nature medicine

Depression is a major contributor to the global burden of diseases with substantial socioeconomic consequences. Here, to estimate the economic effects of depression, we developed a macroeconomic model using data from the World Bank and Global Burden of Disease Study 2021. The model estimated the impact of depression on labor force participation, educational attainment and work experience, adjusted for age and sex. The projected global economic burden from 2025 to 2050 is estimated at US$12 trillion (2024 US dollars), representing 0.460% of annual global gross domestic product. When suicide-related deaths attributable to depression are accounted for, based on an assumed 60% attribution rate representing the upper bound of estimates in the literature, the overall economic burden increases to US$14 trillion. The highest economic burdens are observed in the United States and China. Relative to regional gross domestic product, the impact is greatest in North America. Reduced labor force participation and productivity were identified as the predominant drivers of this cost. The macroeconomic burden of depression is substantial and inequitably distributed globally. These findings underscore the importance of addressing depression as a public health and economic concern. Reducing the health burden of depression could yield economic returns by supporting productivity and capital accumulation.

PLASTID ENVELOPE ION CHANNELS (PEC1/2) link Ca 2+ and jasmonic acid signaling in plant cells.

Plants constantly encounter adverse environmental interactions. One organelle is particularly specialized in stress signaling and phytohormone synthesis: the plastid. Calcium (Ca 2+ ), a key second messenger, is known to intersect with cellular phytohormone signaling networks. While cytosolic Ca 2+ dynamics have been studied extensively, the physiological relevance of stromal Ca 2+ transients and the identity of channels mediating rapid Ca 2+ flux into plastids remain largely unexplored. In this

Structural insights into fosfomycin efflux by a streptococcal ABC transporter.

Gram-positive bacteria encode a broad array of ABC transporters that mediate substrate translocation across the cell membrane, with some contributing to their survival under environmental stresses such as antimicrobial exposure. While several of these transporters have been shown to exhibit multidrug efflux activity, the functional roles of many others remain unknown. Here, using an efflux pump screen in the opportunistic human pathogen Streptococcus pneumoniae , we identified a previously uncha

Detection of "hidden" mitotic crossovers by long-read DNA sequencing.

Mitotic crossovers in diploid organisms are usually detected by looking for loss of heterozygosity (LOH) for a marker. Assuming the crossover occurs between two duplicated chromatids, a single reciprocal crossover will result in two recombinant chromatids and two nonrecombinant chromatids. LOH will only be observed when a recombinant chromatid cosegregates with a nonrecombinant chromatid. Cells containing both recombinant chromosomes will not result in LOH. Below, we use long-range DNA sequencin

Amino acid homeostasis by CORVET/HOPS: A metabolic and stress resilience checkpoint for T cells.

Amino acid sufficiency is critical for T cell metabolic reprogramming, yet how T cells maintain amino acid homeostasis remains poorly defined. Here, we identify the CORVET and HOPS (CORVET/HOPS) tethering complexes as essential upstream regulators. In activated T cells, they sustain intracellular amino acid levels by promoting macropinocytosis to acquire extracellular nutrients. This function enables dual signaling outcomes: suppression of the integrated stress response (ISR) and activation of m

Bright monomeric fluorescent protein elite-niRFP704 for two-channel near-infrared STED nanoscopy.

The near-infrared (NIR) spectral region is attractive for live-cell imaging, due to low autofluorescence and reduced phototoxicity. Some phytochrome-derived fluorescent proteins absorb and emit fluorescence in the NIR, but have short fluorescence lifetimes and relatively low quantum yields, requiring higher laser powers thus limiting their usefulness for live-cell superresolution microscopy. Using the bacterial phytochrome miRFP703 as a template, we screened for variants with longer fluorescence
