Few studies have determined whether the declining incidence of myocardial infarction carries into the current decade, and how it is affected by age and sex. We aimed to determine age- and sex-specific changes in myocardial infarction incidence in Denmark from 2005 through 2021.
First-time myocardial infarction admissions in adults aged ≥18 years were identified through Danish nationwide registries. Incidence rates per 100,000 persons with 95% confidence intervals (CI) were calculated across calendar year, sex, and age groups (≤49, 50-69, 70-84, ≥85 years). We also presented incidence rate ratios (IRR) with 95% CIs for 2019-2021 compared to 2005-2007.
From January 1, 2005, through August 4, 2021, there were 116,481 incident acute myocardial infarctions in approximately 4.5 million Danes aged ≥18 years. Overall incidence rate of myocardial infarction per 100,000 persons decreased in both sexes from 2005 through 2021 (females 143 to 80; males 243 to 174) and across all age groups. The steepest declines in incidence were observed for ages ≥85 years (males 55%, IRR 0.45 [0.41-0.49]; females 58%, IRR 0.42 [0.39-0.45]) and 70-84 years (males 46%, IRR 0.54 [0.52-0.57]; females 52%, IRR 0.48 [0.46-0.51]). Rates also declined significantly for ages 50-69 (males 19%, IRR 0.81 [0.79-0.84]; females 17%, IRR 0.83 [0.78-0.88]) and ≥49 years (males 30%, IRR 0.70 [0.64-0.76]; females 37%, IRR 0.63 [0.54-0.74]).
Declines in the incidence of myocardial infarction continued into the current decade across age groups and sex. However, significantly steeper absolute and relative declines were observed among the oldest age groups (≥70 years).

The present study addresses this research gap by surveying N = 702 managers in three European countries (Germany, United Kingdom, Spain) about their expectations and concerns regarding sensor-based monitoring of employee mental workload. The data confirm the relevance of expectations regarding improvements of workplace design and employee well-being, as well as concerns about restrictions of employees' privacy and sovereignty, for the implementation of workload monitoring. see more Furthermore, Bayesian regression models show that the examined expectations have a substantial positive association with managers' willingness to support workload monitoring in their company. Privacy concerns are identified as a significant barrier to the acceptance of workload monitoring, both in terms of their prevalence among managers and their strong negative relationship with monitoring support.Iron(II) [Fe(II)] oxidation coupled to denitrification is recognized as an environmentally important process in many ecosystems. However, the Fe(II)-oxidizing bacteria (FeOB) dominating autotrophic nitrate-reducing Fe(II)-oxidizing enrichment cultures, affiliated with the family Gallionellaceae, remain poorly taxonomically defined due to lack of representative isolates. We describe the taxonomic classification of three novel FeOB based on metagenome-assembled genomes (MAGs) acquired from the autotrophic nitrate-reducing enrichment cultures KS, BP and AG. Phylogenetic analysis of nearly full-length 16S rRNA gene sequences demonstrated that these three FeOB were most closely affiliated to the genera Ferrigenium, Sideroxydans and Gallionella, with up to 96.5%, 95.4% and 96.2% 16S rRNA gene sequence identities to representative isolates of these genera, respectively. In addition, average amino acid identities (AAI) of the genomes compared to the most closely related genera revealed highest AAI with Ferrigenium kumadai An22 (76.35-76.74%), suggesting that the three FeOB are members of this genus. Phylogenetic analysis of conserved functional genes further supported that these FeOB represent three novel species of the genus Ferrigenium. Moreover, the three novel FeOB likely have characteristic features, performing partial denitrification coupled to Fe(II) oxidation and carbon fixation. Scanning electron microscopy of the enrichment cultures showed slightly curved rod-shaped cells, ranging from 0.2-0.7 μm in width and 0.5-2.3 μm in length. Based on the phylogenetic, genomic and physiological characteristics, we propose that these FeOB represent three novel species, 'Candidatus Ferrigenium straubiae' sp. nov., 'Candidatus Ferrigenium bremense' sp. nov. and 'Candidatus Ferrigenium altingense' sp. nov. that might have unique metabolic features among the genus Ferrigenium.The Body Appreciation Scale-2 (BAS-2) is the most current measure of body appreciation, a central facet of positive body image. This work aimed to examine the factor structure and psychometric properties of a German version. In Study 1 (N = 659; Mage = 27.19, SD = 8.57), exploratory factor analysis (EFA) revealed that the German BAS-2 has a one-dimensional factor structure in women and men, showing cross-gender factor similarity. In Study 2 (N = 472; Mage = 30.08, SD = 12.35), confirmatory factor analysis (CFA) further supported the original scale's one-dimensional factor structure after freeing correlated errors. The German BAS-2 also showed partial scalar invariance across gender, with women and men not differing significantly in latent mean scores. As predicted, we found convergent relationships with measures of self-esteem, intuitive eating, and variables associated with negative body image (i.e., weight- and shape concerns, drive for thinness). Correlations with BMI were small and in an inverse direction. Incremental validity was demonstrated by predicting self-esteem and intuitive eating over and above measures of negative body image. Additionally, the German BAS-2 showed internal consistency and 2-week test-retest reliability. Overall, our results suggest that the German BAS-2 is a psychometrically sound instrument.Determination of atrazine (ATZ) residues in aquatic environment has important theoretical and practical significance for protecting the ecological environment and ensuring human health. A photoelectrochemical (PEC) aptasensing based on nitrogen deficiency and cyano group simultaneously engineered two-dimensional (2D) carbon nitride (named as DCN) has been proposed for sensitively detecting ATZ. The introduction of nitrogen deficiency can narrow band gap of DCN, leading to positive position of intermediate electronic state, and improving the absorption of visible light. The intermediate electronic state can function as an electron trap to promote the separation and migration of photogenerated carriers. Cyano groups can trap photoinduced electrons and suppress charge recombination. Gas produced by thermal decomposition has a tailoring effect, endowing DCN with 2D ultra-thin structure, which shortens transmission path of carriers. The synergistic effect of the above enhances PEC performance of DCN. The PEC aptasensing exhibited a wide linear range of 1.0 × 10-4 to 1.0 × 103 pM and a low detection limit of 3.33 × 10-5 pM with excellent selectivity, stability, and satisfactory accuracy during detecting real samples. The proposed design of carbon nitride-based materials may provide a better understanding of the relationship between kind of photoactive materials and PEC performance.Scalp cooling is currently the most approved treatment to prevent alopecia due to chemotherapy for cancer. Few reports can be available, and the mechanisms involved in scalp cooling were unclear. The present work tries to reveal a preliminary inhibitory mechanism of scalp cooling on paclitaxel-induced alopecia. The results found that low temperature enhanced local vasoconstriction to 0.32 (dimensionless diameter, @ 22 °C) and the vascular diameter presented an oscillating attenuation, which led to the concentration reduction of chemotherapeutic drugs transported by blood flow. Cooling significantly rescued M-HFK cells treated by paclitaxel, and the lower temperature for the better protection due to weakening the cytotoxicity in some extent. Cell cycle results showed that the G0/G1 phase was arrested at low temperature (i.e. 22 °C), which was beneficial to mitigate the effect of paclitaxel on the G2/M phase cycle and finally made the cell cycle return to normal. Also, cold stimulation significantly increased the concentration of HSP70 more than 3 times (@22 °C for 2h) compared with that of the control group, which means low temperature can protect cells from stresses. Furtherly, Cooling reduced the number of PH3+ and Caspase-3+ cells in the hair follicle, and effectively inhibited the cell apoptosis in the vitro hair follicle and alopecia in the mice experiments. The current work provides a basis for deeply understanding the chemotherapy-induced alopecia prevention with scalp cooling.Radiotherapy is an important treatment modality for cancer patients. Ionizing radiation kills cancer cells by inducing DNA damage. However, it remains unclear how this process affects the biomechanical properties of cells and how cellular mechanics affect DNA damage and repair. In this study, the effects of ionizing radiation on cell mechanics were investigated by precisely measuring the compressibility of cells in suspension using an in-house developed microfluidic device. We found that cell compressibility significantly increased after irradiation, depending on cell type and radiation dose. Radiation-induced DNA damage response (DDR) is an important process that alters cell mechanics, and this association was confirmed experimentally by inhibiting the DDR process. Furthermore, the mechanisms involved in changes in cell compressibility were investigated from the perspective of the nucleus and cytoplasm. Experiments showed that radiation reduced H3K9me3 staining intensity but had no effect on F-actin. This suggested that chromatin decondensation caused by radiation-induced DDR is the primary cause of changes in cell compressibility after radiation. The effects of cell mechanics on radiation-induced DNA damage were also investigated. The addition of blebbistatin reduced cytoskeletal forces on the nucleus, which resulted in a reduction in radiation-induced DNA damage. Collectively, this study elucidated reciprocal mechanisms of radiation-induced DNA damage and cell mechanics.α-ketoisocaproic acid (AKA), a metabolite of l-leucine, is one of the branched-chain amino acids (BCAAs) involved in energy metabolism. However, the effects of AKA on lipid metabolism, insulin signaling, and related mechanisms in preadipocytes have not been reported. Herein, we investigated the impacts of AKA on lipid accumulation in 3T3-L1 murine preadipocytes. Treatment with AKA for 4 days enhanced lipid accumulation and expression of lipogenic proteins, such as cleaved sterol-regulatory element-binding proteins (SREBP1) and stearoyl-CoA desaturase-1 (SCD1) in 3T3-L1 cells. Increased endoplasmic reticulum (ER) stress markers, such as phosphorylation of eukaryotic initiation factor 2 (eIF2) and CHOP, were observed in the presence of AKA. AKA treatment increased mTOR phosphorylation and reducing autophagy markers, such as LC3 conversion and degradation of p62. Treatment with rapamycin, an mTOR inhibitor, reduced the effects of AKA on ER stress and lipogenesis in 3T3-L1 preadipocytes. The present study demonstrates that AKA increases ER stress by impairing mTOR/autophagy signaling, thus promoting lipid accumulation and insulin resistance in preadipocytes.
