RESUMEN
BACKGROUND: Cadmium (Cd) and lead (Pb) exhibit nephrotoxic activity and may accelerate kidney disease complications in diabetic patients, but studies investigating the relation to diabetic kidney disease (DKD) have been limited. We aimed to examine the associations of Cd and Pb with DKD in diabetic patients. METHODS: 3763 adults with blood metal measurements and 1604 adults with urinary ones who were diabetic from National Health and Nutrition Examination Survey (NHANES) 2007-2016 were involved. Multivariate logistic regression models were used to analyze the associations of blood Cd (BCd), blood Pb (BPb), urinary Cd (UCd), and urinary Pb (UPb) with DKD. RESULTS: BPb, BCd, and UCd levels were higher among participants with DKD than diabetics without nephropathy, but UPb performed the opposite result. BPb and UCd were significantly associated with DKD in the adjusted models (aOR, 1.17 (1.06, 1.29);1.52 (1.06, 2.02)). Participants in the 2nd and 3rd tertiles of BPb and BCd levels had higher odds of DKD, with a significant trend across tertiles, respectively (all P-trend < 0.005). Multiplication interaction was also identified for BPb and BCd (P for interaction = 0.044). CONCLUSION: BPb, BCd, and UCd were positively associated with the risk of DKD among diabetic patients. Furthermore, there were the dose-response relationship and multiplication interaction in the associations of BPb, BCd with DKD.

OBJECTIVES: Research indicates adverse childhood experiences (ACEs) were associated with subjective cognitive decline (SCD), with higher ACEs reported by sexual minoritized individuals (i.e. lesbian, gay, and bisexual; LGB). This study aimed to explore the relationships between ACEs and SCD based on sexual orientation in middle-aged and older adults. METHODS: The study included 76,592 participants from the 2019-2020 Behavioral Risk Factor Surveillance Survey (BRFSS). Multivariate logistic regressions analyzed ACEs status, score, and type associations with SCD. RESULTS: 2.18% of the participants identified as sexual minoritized individuals. More sexual minoritized individuals reported SCD compared to heterosexual individuals (10.70% for heterosexuals; 17.27% for sexual minoritized individuals). Positive association between SCD and ACEs status (OR = 2.18, 95%CI: 1.09-4.40) was identified among sexual minoritized individuals. CONCLUSIONS: The association between ACEs and SCD was strong in both heterosexual and sexual minoritized populations. Given the higher experience of ACEs among sexual minoritized adults, the subsequent frequency of SCD among these adults also may be higher. CLINICAL IMPLICATIONS: Sexual minoritized older adults may have a history of numerous ACEs, which could contribute to a greater burden of SCD. Clinicians and other stakeholders may wish to consider relationships between ACEs and SCD based on sexual orientation.
RESUMEN
OBJECTIVES: Autophagy is critical for myocardial ischemia-reperfusion (I/R) injury. However, there is still considerable debate over its protective and deleterious effects. The purpose of this study was to determine the involvement of the proprotein convertase subtilisin/Kexin type 9 (PCSK9) and its inhibitor in myocardial ischemia-reperfusion injury autophagy (MRI). METHODS: Nine groups of eighty rats were used: sham, I/R2 h, I/R4 h, I/R6 h, I/R8 h, I/R1 d, and I/R2 d. A 30-min coronary artery blockage was used to produce myocardial IR. The time required for reperfusion rose linearly with the time gradient, from 2 h to 2 days. Following the determination of the best reperfusion period, three groups were formed: sham, I/R, and I/R + P (PCSK9 inhibitor (evolocumab) 10 mg/kg diluted in 2 ml sterile injection water was administered subcutaneously 1 week and half an hour before to surgery. Each group's infarction area was determined by electrocardiography (ECG), cardiac function, and 2,3,5-triphenyltetrazolium chloride (TTC) /Evan Blue (EB) staining. To detect morphological alterations in myocardial cells in each group, hematoxylin and eosin (HE) staining was used. Meanwhile, western blotting, immunohistochemistry, and Masson trichrome staining were utilized to quantify myocardial fibrosis and PCSK9 and autophagy protein expression. RESULTS: The results indicated that PCSK9 expression levels increased significantly in MRI, as indicated by increased levels of the autophagy regulatory protein light chain 3 (LC3) and Beclin-1, which activated autophagy in cardiomyocytes, exacerbated myocardial injury, and increased the size of myocardial infarcts. Meanwhile, PCSK9 regulates mitophagy via the Bcl-2/adenovirus E1B 19-kDa interacting protein (BNIP3) pathway, which controls myocardial infarction MRI throughout. Additionally, the PCSK9 inhibitor significantly decreased autophagy, enhanced cardiac function, and reduced the extent of reperfusion injury, consequently reducing myocardial infarct size expansion. CONCLUSION: PCSK9 is upregulated in the myocardial ischemia-reperfusion injury hearts and regulates mitophagy via the BNIP3 pathway, which in turn contributes to reperfusion injury after myocardial infarction. PCSK9 inhibition protects against myocardial ischemia-reperfusion injury via suppressing autophagy.

BACKGROUND: Depressive disorder is a severe global public health problem. It is crucial to evaluate the global incidence trends of depressive disorder. METHODS: The incidence data were drawn from the Global Burden of Disease Study (GBD) 2019. Estimates were presented by global and sociodemographic index (SDI) quintiles, and the age-period-cohort (APC) model was used to estimate the incidence trends. RESULTS: APC analysis indicated a decline in depressive disorder incidence globally (net drift = -0.24%, 95%CI: -0.29, -0.18), except for an increase in SDI regions (net drift = 0.07, 95%CI:0, 0.14). In high SDI regions, depressive disorder incidence increased among the younger and declined among the elder population, whereas the opposite trend was observed in middle and low-middle SDI regions. The depressive disorder incidence increased significantly among people aged 15 to 24 years after adjusting for age effects, decreased since 2000 after adjusting for period effects and increased rapidly in the birth cohort after 1990 in high SDI by adjusting for cohort effects. CONCLUSION: Globally, there was a declining trend of depressive disorder incidence in 1990-2019. Specifically, the incidence was declining globally in younger populations, while increasing in older populations. However, this trend differed depending on the SDI of the region.

This study investigates sex differences in the effects of macronutrient quantity, quality, and timing on mortality in metabolically unhealthy overweight/obesity (MUO) populations. The study included 18,345 participants, including 9204 men and 9141 women. The Cox proportional risk model and isocaloric substitution effects were used to examine the association of macronutrient intake and subtype with all-cause mortality in the MUO populations. After adjusting for the potential covariates, The risk of all-cause mortality was elevated in men in the highest 25% percentile of poor-quality carbohydrates compared with men in the lowest quartile (odds ratio [OR]: 2.04; 95% confidence interval [CI], 1.40-2.98). Compared with women in the lowest quartile, the risk of all-cause mortality for women in the highest 25% percentile for high-quality carbohydrates (OR: 0.74; 95% CI, 0.55-0.99) and unsaturated fatty acids (OR: 0.54; 95% CI, 0.32-0.93) were decreased. In women, replacing low-quality carbohydrates with high-quality carbohydrates on an isocaloric basis reduces the risk of all-cause mortality by approximately 9%. We find that different macronutrient consumption subtypes are associated with all-cause mortality in MUO populations, with differential effects between men and women, and that the risk of all-cause mortality is influenced by macronutrient quality and meal timing.

BACKGROUND: The association between change in lifestyle and cognitive impairment remains uncertain. OBJECTIVES: To investigate the association of change in lifestyle with cognitive impairment. METHODS: In this study, 4 938 participants aged 65 or older were involved from the Chinese Longitudinal Healthy Longevity Survey for years 2008-2018. A weighted healthy lifestyle score was derived from 4 lifestyle factors (smoking, alcohol consumption, physical activity, and diet). Multivariable Cox proportional hazards regression models were applied to investigate the associations between 3-year changes in healthy lifestyle (2008-2011) and cognitive impairment (2011-2018). RESULTS: Researchers documented 833 new-onset of cognitive impairments more than 20 097 person-years of follow up. Compared with those in the persistently unhealthy group, those in the improved and persistently healthy groups had a lower risk of cognitive impairment, with the multivariate-adjusted hazard ratios (HRs) of 0.67 (95% confidence interval (CI): 0.55, 0.83) and 0.53 (95% CI: 0.40, 0.71), respectively. Furthermore, a significant interaction was observed between change in lifestyle and sex (p-interactionâ =â .032); the HRs were 0.48 (95% CI, 0.34, 0.69) for the improved group and 0.41 (95% CI: 0.26, 0.64) for persistently healthy group among male vs 0.81 (95% CI, 0.63, 1.04) and 0.64 (95% CI, 0.44, 0.92) among female, respectively. CONCLUSIONS: This study suggests that improving or maintaining a healthy lifestyle can significantly mitigate the risk of cognitive impairment in Chinese older adults. Additionally, researcher's findings emphasize the significance of maintaining a healthy lifestyle and highlights the potential positive impact of improving previous unhealthy habits, especially for older women.

PURPOSE: This study aimed to examine independent association between inflammatory biomarkers and all-cause mortality as well as cardio-cerebrovascular disease (CCD) mortality among U.S. adults with diabetes. METHODS: A cohort of 6412 U.S. adults aged 20 or older was followed from the start until December 31, 2019. Statistical models such as Cox proportional hazards model (Cox) and Kaplan-Meier (K-M) survival curves were employed to investigate the associations between the inflammatory biomarkers and all-cause mortality and CCD mortality. RESULTS: After adjusting for confounding factors, the highest quartile of inflammatory biomarkers (NLR HR = 1.99; 95 % CI:1.54-2.57, MLR HR = 1.93; 95 % CI:1.46-2.54, SII HR = 1.49; 95 % CI:1.18-1.87, SIRI HR = 2.32; 95 % CI:1.81-2.96, nLPR HR = 2.05; 95 % CI:1.61-2.60, dNLR HR = 1.94; 95 % CI:1.51-2.49, AISI HR = 1.73; 95 % CI:1.4 1-2.12)) were positively associated with all-cause mortality compared to those in the lowest quartile. K-M survival curves indicated that participants with an inflammatory biomarker above a certain threshold had a higher risk of both all-cause mortality and CCD mortality (Log rank P < 0.05). CONCLUSION: Some biomarkers such as NLR, MLR, SII, AISI, SIRI, and dNLR, are significantly associated with all-cause mortality and CCD mortality among U.S. adults with diabetes. The risk of both outcomes increased when the biomarkers surpassed a specific threshold.

Metabolic factors are major and controllable risk factors for cardiovascular diseases (CVD), and few studies have described this burden. We aim to assess it from 1990 to 2019 and predict the trends through 2034. Global Burden of Disease (GBD) provides data on sex, age, and socio-demographic index (SDI) levels. Numbers, age-standardized death rates (ASDR) and estimated annual percentage change (EAPC) were used. Future trends were estimated by NORDPRED model. The deaths cases of metabolic-related CVD increased from 8.61 million (95% UI: 7.91-9.29) to 13.71 million (95% UI: 12.24-14.94) globally. The ASDR continued to decline globally (EAPC = -1.36). The burden was heavier in male and middle-aged people and elderly people. CVD-related ASDR caused by high systolic blood pressure (SBP) had a downward trend globally (EAPC = -1.45), while trends of high body mass index (BMI) (EAPC = 1.29, 1.97, 0.92) and fasting plasma glucose (FPG) (EAPC = 0.95, 1.08, 0.46) were increasing in the middle, low-middle, and low SDI regions, respectively. Compared to 2015-2019, cumulative deaths will increase by 27.85% from 2030 to 2034, while ASDR will decrease 10.47%. The metabolic-related CVD burden remained high globally and deaths will continue to rise in the future. Men, middle-aged and elderly people were focus of concern. High SBP was globally well-managed over the past 30 years, but the CVD burden due to high BMI and FPG remained high. Exceptional initiatives are needed to regarding interventions targeting high BMI and FPG in middle and lower SDI regions.
RESUMEN
BACKGROUND: This observational cross-sectional study was designed to explore the effects of a low-carbohydrate diet (LCD) and a low-fat diet (LFD) on metabolic-dysfunction-associated fatty liver disease (MAFLD). METHODS: This study involved 3961 adults. The associations between LCD/LFD scores and MAFLD were evaluated utilizing a multivariable logistic regression model. Additionally, a leave-one-out model was applied to assess the effect of isocaloric substitution of specific macronutrients. RESULTS: Participants within the highest tertile of healthy LCD scores (0.63; 95% confidence interval [CI], 0.45-0.89) or with a healthy LFD score (0.64; 95%CI, 0.48-0.86) faced a lower MAFLD risk. Furthermore, compared with tertile 1, individuals with unhealthy LFD scores in terile 2 or tertile 3 had 49% (95%CI, 1.17-1.90) and 77% (95%CI, 1.19-2.63) higher risk levels for MAFLD, respectively. CONCLUSIONS: Healthy LCD and healthy LFD are protective against MAFLD, while unhealthy LFD can increase the risk of MAFLD. Both the quantity and quality of macronutrients might have significant influences on MAFLD.

Purpose: Astragalus-cultivated soils are enriched in arbuscular mycorrhizal fungi (AMF); however, the community changes of AMF between years in stragalus-cultivated soils are still unclear. Methods: To illustrate this, using high-throughput amplicon sequencing and quantitative real-time PCR, we analyzed the AMF communities of the abandoned farmlands and interannual astragalus-cultivated soils for 1-, 2-, 3-, and 4-years, including community composition, dominant, core, specific and significantly fluctuating AMF, co-occurrence network, alpha diversity, and beta diversity. Results: A total of 74 OTUs were classified into one phylum, Glomeromycota; one class, Glomeromycetes; four orders; four families; and six genera. The 2-year soil had the highest number of reads among the interannual soils. Only one OTU was shared among all interannual soils. The treatments significantly affected the Ace, Shannoneven, and Shannon estimators of the communities. The 2-year soil had the highest richness, evenness, and diversity among all interannual soils and was the closest to the abandoned farmland in terms of alpha diversity. Glomus of the family Glomeraceae was the dominant genus present in all treatments, and the composition of the dominant genus in interannual soils was different. Both Glomus and Diversispora were the core AMF in interannual soils, and specific AMF existed in different interannual soils. Glomus is a genus that exhibits significant interannual variation. The interannual time significantly affected the network connectivity. The results of the principal coordinate analysis showed that the community composition of the interannual soils was close to each other and separated from the abandoned farmland, and that the interannual time significantly affected the community composition. Conclusion: Among the interannual soils, the 2-year soil may be more suitable for A. sinensis seedling rotation.
RESUMEN
It is surprising that, while arsenic trioxide (ATO) is now considered as "the single most active agent in patients with acute promyelocytic leukemia (APL)", the most important discoverer remains obscure and his original papers have not been cited by a single English paper. The discovery was made during the Cultural Revolution when most Chinese scientists and doctors struggled to survive. Beginning with recipes from a countryside practitioner that were vague in applicable diseases, Zhang TingDong and colleagues proposed in the 1970s that a single chemical in the recipe is most effective and that its target is APL. More than 20 years of work by Zhang and colleagues eliminated the confusions about whether and how ATO can be used effectively. Other researchers, first in China and then in the West, followed his lead. Retrospective analysis of data from his own group proved that APL was indeed the most sensitive target. Removal of a trace amount of mercury chloride from the recipe by another group in his hospital proved that only ATO was required. Publication of Western replication in 1998 made the therapy widely accepted, though neither Western, nor Chinese authors of English papers on ATO cited Zhang's papers in the 1970s. This article focuses on the early papers of Zhang, but also suggests it worth further work to validate Chinese reports of ATO treatment of other cancers, and infers that some findings published in Chinese journals are of considerable value to patients and that doctors from other countries can benefit from the clinical experience of Chinese doctors with the largest population of patients.
