The Six Worst U.S. Health Disasters of the Last 50 Years

Up until the first half of the twentieth century, large-scale health disasters were mostly due to natural causes (earthquakes, volcanoes, hurricanes, etc.) or infections (e.g., smallpox, influenza epidemics, cholera). But something peculiar happened as we entered the second half of the century: Health disasters due to natural causes became dwarfed by large-scale health disasters that are man-made. Here’s a list of the Six Worst U.S. Health Disasters of the Last 50 Years, mostly man-made phenomena that have exacted huge tolls: widespread disease, premature death, poorly managed (though nonetheless highly profitable for healthcare insiders–but perhaps that is the rub). This is not to make light of the lesser health disasters over the same time period, ranging from lead poisoning in children, to E. coli contamination of high-volume commercial produce, to proliferation of gun violence. But it highlights the tidal wave of change in the landscape of health disasters. We have gone from being victims of forces beyond our control to forces that are under human influence, even profitable to those “properly” positioned.   The Six Worst U.S. Health Disasters of the Last 50 Years The U.S. Dietary Guidelines for Americans–A joint effort between the U.S. Department of Health and Human Services (HHS) and the Department of Agriculture (USDA) resulted in the first U.S. Dietary Guidelines for Americans in 1980—and the American public has yet to recover f...

ConclusionsThe findings showed the presence of antibiotic resistance in probiotic bacteria isolated from commercially available dietary supplements. As multidrug resistance is a serious emerging issue and the risk of drug resistant gene transfer to commensals or pathogens of the gut is inevitable, the safety of probiotics has become a major criterion of interest. The findings of this study would serve as a platform for further screening and characterization of the determinants of antibiotic resistance and the genetic mechanisms of resistance.

This study characterized Listeria monocytogenes, Salmonella enterica, and E. coli O157:H7 by collecting rectoanal mucosal swabs and fecal samples from 518 imported beef cattle at Jordan’s major abattoir. A unique 53 L. monocytogenes, 287 S. enterica, and 17 E. coli O157:H7 were isolated from 37, 120 and 9 different animals; respectively. The prevalence of S. enterica, L. monocytogenes and E. coli O157:H7 were 23.2% (95% CI, 19.7-27.0%), 7.1% (95% CI, 5.2-9.7%) and 1.7% (95% CI, 0.9-3.3%); respectively. All L. monocytogenes, all E. coli O157:H7 and 93.0% of S. enterica isolates resisted at least one antimicrobial clas...

Authors: Fan D, Yang S, Han Y, Zhang R, Yang L Abstract MicroRNAs (miRNAs) are widely known as critical regulators in isoflurane-induced neurotoxicity during the development of brain. Moreover, isoflurane could aggravate cognitive impairment in diabetic rats. The present study was designed to investigate the role and mechanism of miR-140-5p on isoflurane-induced neurotoxicity in diabetic rats. Firstly, a diabetic rat model was established by injection of streptozotocin (STZ) and identified by Morris water maze test. The result indicated that isoflurane treatment exacerbated STZ-induced cognitive impairment, as demo...

Authors: Ma Q, Shao Y, Chen W, Quan C, Zhu Y, Xu X, Zhou Z, Wang S Abstract Aim: To investigate whether cervical cancer (CC) and cervical intraepithelial neoplasia (CIN) can be screened by analyzing gene expression profiling of peripheral blood. Methods: RNA-sequencing analysis of blood was performed on 11 CC patients, 21 CIN patients and 19 healthy controls (H). Fifty-nine genes were validated by quantitative real-time PCR using blood samples from 46 H, 83 CC and 32 CIN patients. Results: There were significant differences in the expression levels of six genes between CC and H, five genes between CIN and H and fou...

Authors: Deng Z, Wu J, Xu S, Chen F, Zhang Z, Jin A, Wang J Abstract Exosomes have appeared as fundamental vehicle-modulated crosstalk among various cells in the tumor microenvironment. The systematic understanding of exosomes in gastric cancer (GC) enhances our comprehension about the tumor growth, metastasis, chemoresistance and diagnosis of cancers. The versatile functions of exosomes provide reasonable explanations about the propensity for GC metastasis. The selectively enriched components, especially some exosomal miRNAs, are potential noninvasive biomarkers for sensitive and specific GC diagnosis. Given the c...

This study aimed to quantitatively grasp the structure of support for balancing cancer treatment and work among occupational health nurses (OHNs) with the current implementation status. The anonymous questionnaire was designed based on the findings of our previous qualitative study and distributed to OHNs. The degrees of support implementation for workers with cancer, superiors and colleagues, and human resource managers were assessed for each item. Factor analysis of support items was conducted, and Wilcoxon signed-rank test was carried out to compare the support scores between the factors. Support for workers with cancer...

It has become a major risk factor of human diseases, including diabetes, cancers, cardiovascular diseases and neurodegenerative diseases. Silencing information regulator 2 related enzyme 1(sirtuin1, SIRT1) is an NAD+-dependent deacetylase, which has been reported to be involved in the regulation of cellular senescence and aging. The expression of SIRT1...
