To estimate the annual and lifetime economic productivity loss due to adult out-of-hospital cardiac arrest (OHCA) in the United States (U.S.).
All adult (age≥18years) non-traumatic EMS-treated OHCA with complete data for age, sex, race, and survival outcomes from the CARES database for 2013-2018 were included. Annual and lifetime labor productivity values, based on age and gender, were obtained from previously published national economic data. Productivity losses for OHCA events were calculated by year in U.S. dollars. Productivity losses for survivors were assigned by cerebral performance category score (CPC) CPC 1 and 2=0% productivity loss; CPC 3-5=100% productivity loss. Sensitivity analyses were performed assigning CPC 2 varying productivity losses (0-100%) based on CPC score and discharge location. Lifetime productivity values assumed 1% annual growth and 3% discount rate and were adjusted for inflation based on 2016 values. Results were extrapolated to annual U.S. population estimates for the study period.
A total of 338,492 (96.5%) cases met inclusion criteria. The mean annual and lifetime productivity losses per OHCA in 2018 were $48,224 and $638,947 respectively. The total annual economic productivity loss due to OHCA in the U.S. increased from $7.4B in 2013 to $11.3B in 2018. Lifetime economic productivity loss increased from $95.2B in 2013 to $150.2B in 2018. Sensitivity analyses yielded similar findings. Per annual death, OHCA ranked third ($10.2B) in annual economic productivity loss in the U.S. behind cancer ($22.9B) and heart disease ($20.3B) in 2018.
Adult non-traumatic OHCA events are associated with significant annual and lifetime economic productivity losses and should be the focus of public health resources to improve preventative measures and survival outcomes.

Using memory reactivation and emotional updating manipulations, we investigated how positive and neutral emotion may update aversive memories for reconsolidation in humans. We found that positive updating after reactivation was equivalent to neutral updating in impairing true memories of a previous aversive event after a 12-hour wakeful delay, but induced more false memory. Moreover, additional 12-hour delay with overnight sleep did not further enlarge true memory differences, but attenuated the effect of reactivation and updating on false memory. Interestingly, the neutral rather than the positive updating reduced the emotional arousal of the aversive memory 24 h later. Our findings could serve as a reference for real-world therapeutic applications regarding how positive and neutral updating may reshape aversive memories, especially when taking wake- and sleep-filled reconsolidation into account.Cell destruction in Hashimoto's thyroiditis (HT) involves autoantibodies and cytotoxic T lymphocytes. Thyrocytes maintenance occurs by pro-apoptotic, anti-apoptotic and cell proliferation balance.
To characterize factors related to the mechanisms of apoptosis and cell proliferation in thyroid cells and intrathyroid lymphocytic infiltrate in HT.
We assessed lymphocytic infiltrate and thyroid cells from HT and normal thyroid by immunohistochemical analysis of cell proliferation (Ki-67), antiproliferation (p27Kip1), pro-apoptosis (Fas, Fas-ligand, BID) and anti-apoptosis (MCL-1, BCL2) markers.
Lymphocytic infiltrate presented BCL2 and MCL-1 higher expression, Ki-67 and p27kip1 balance. Thyrocytes exhibited Fas and FasL balance, higher BID expression; MCL-1, BCL-2, Ki-67 similar to the normal thyroid. T4 and higher lymphocytes BID expression were associated.
In lymphocytic infiltrate predominated anti-apoptosis in relation to pro-apoptosis except for BID. Thyrocytes presented pro-apoptosis and anti-apoptosis balance and cell proliferation similar to normal thyroid. T4-associated BID expression in HT lymphocytes suggests the influence of thyroid hormone as a signal to up-regulate the BID pro-apoptotic protein and thus increase lymphocytic apoptosis rates.

Hyponatraemia is frequently observed in cancer patients and can be due to the syndrome of inappropriate anti-diuresis (SIAD), related to ectopic vasopressin secretion, particularly in small cell lung cancer (SCLC). Hyponatraemia is associated with a worse outcome in cancer patients. The vasopressin receptor antagonist tolvaptan effectively corrects hyponatraemia secondary to SIAD and there is in vitro evidence that it has also an antiproliferative effect in cancer cells. The purpose of this study was i) to analyse the effect of low serum sodium concentrations ([Na
]) in SCLC cells and ii) to determine whether tolvaptan counteracts tumor progression.
We evaluated cell proliferation, cell cycle, apoptosis, oxidative stress, invasivity in low [Na
] as well as after exposure to tolvaptan. We also analysed the intracellular signalling pathways involved.
In reduced [Na
] cell proliferation was significantly increased compared to normal [Na
] and cells were mostly distributed in the G2/M phase. Apoptosis appeared reduced. In addition, the ability to cross matrigel-coated membranes markedly increased. As observed in other cancer cell models, the expression of the heme-oxigenase-1 gene was increased. Finally, we found that in cells cultured in low [Na
] the RhoA/ROCK1/2 pathway, which is involved in the regulation of actin cytoskeleton, was activated. On the other hand, we found that tolvaptan effectively inhibited cell proliferation, anchorage-independent growth, invasivity and promoted apoptosis. Accordingly, the RhoA/ROCK-1/2 pathway was inhibited.
These findings demonstrate for the first time that low [Na
] favours tumor progression in SCLC cells, whereas tolvaptan effectively inhibits cell proliferation, survival and invasivity.

In the traditional medicine system, plants have been utilized as a rich source of anti-microbial, anti-inflammatory, anti-cancer, anti-viral and anti-oxidant compounds. The biological properties of plant-based drugs depend on their interaction with endophytes which persist as an important provider of bioactive secondary metabolites. Bacterial endophytes secrete anti-inflammatory molecules whose activity can be the base for the anti-inflammatory property of the plant.
During the screening of endophytes from Emilia sonchifolia, we isolated six different bacteria whose potential as the sources of anti-inflamamtory compounds have been aimed at in this study.
Anti-inflammatory activity of the ethyl acetate extract of endophytes was studied by both in vitro and in vivo analyses. In vitro study was done using protein denaturation, COX, LOX, iNOS, myeloperoxidase and nitric oxide assays and in vivo analysis was carried out by carrageenan-induced and formalin-induced paw oedema tests. The expression level of antand thus justifies the possible role of endophytes in contributing anti-inflammatory property to E sonchifolia which is ethno-botanically important as a source of anti-inflammatory drug.The human brain demonstrates anatomical and functional lateralization/asymmetry between the left and right hemispheres, and such asymmetry is known to start from the early age of life. However, how the asymmetry changes with brain development during infancy remained unknown. In this study, we aimed to systematically investigate the spatiotemporal pattern of brain asymmetry in healthy preterm-born infants during the first-half-year of development, using high angular resolution diffusion MRI. Sixty-five healthy preterm-born infants (gestational age between 25.3-36.6 weeks) were scanned with postmenstrual age (PMA) ranging from term-equivalent age (TEA) to 6-months. At the regional level, we performed a region-of-interest-based analysis by segmenting the brain into 63 symmetrical pairs of regions, based on which the laterality index was assessed and correlated with PMA. At the voxel level, we performed a fixel-based analysis of each fiber component between the native and left-right flipped data, separately in TEfronto-occipital fasciculus showed significant leftward asymmetry and the extent of asymmetry increased with PMA. In summary, the results revealed unique spatiotemporal patterns of macro- and micro-structural asymmetry in early life, which dynamically changed with age. These findings may contribute to the understanding of brain development during infancy.Functional connectivity (FC), or the statistical interdependence of blood-oxygen dependent level (BOLD) signals between brain regions using fMRI, has emerged as a widely used tool for probing functional abnormalities in clinical populations due to the promise of the approach across conceptual, technical, and practical levels. With an already vast and steadily accumulating neuroimaging literature on neurodevelopmental, psychiatric, and neurological diseases and disorders in which FC is a primary measure, we aim here to provide a high-level synthesis of major concepts that have arisen from FC findings in a manner that cuts across different clinical conditions and sheds light on overarching principles. We highlight that FC has allowed us to discover the ubiquity of intrinsic functional networks across virtually all brains and clarify typical patterns of neurodevelopment over the lifespan. This understanding of typical FC maturation with age has provided important benchmarks against which to evaluate divergent maturation in early life and degeneration in late life. This in turn has led to the important insight that many clinical conditions are associated with complex, distributed, network-level changes in the brain, as opposed to solely focal abnormalities. We further emphasize the important role that FC studies have played in supporting a dimensional approach to studying transdiagnostic clinical symptoms and in enhancing the multimodal characterization and prediction of the trajectory of symptom progression across conditions. We highlight the unprecedented opportunity offered by FC to probe functional abnormalities in clinical conditions where brain function could not be easily studied otherwise, such as in disorders of consciousness. Lastly, we suggest high priority areas for future research and acknowledge critical barriers associated with the use of FC methods, particularly those related to artifact removal, data denoising and feasibility in clinical contexts.
