The blood cultures were positive for Klebsiella pneumoniae. The patient died.

In our case, we describe a community-onset, healthcare-facility-associated, severe CDI complicated by a blood stream infection. The administration of oral Vancomycin, which is highly active against the intestinal flora, could have been responsible for the persistence and overgrowth of Klebsiella pneumoniae.

Severe CDIs after orthopaedic surgery and antibacterial treatment complicated by the development of nosocomial infection significantly worsen the prognosis of the disease. Careful consideration of antibacterial therapy and early symptom recognition may help prevent catastrophic events.

Lemierre's syndrome is a rare and potentially fatal entity characterized by the spread of an oropharyngeal infection, with secondary suppurative thrombophlebitis of the internal jugular vein and septic emboli.

We discuss the case of a 52-year-old male who developed Lemierre's syndrome following peritonsillar abscess. He presented with submandibular and submental swelling extending into the neck. His management included; incision and drainage of the abscesses; and prolonged anticoagulant therapy.

The incidence of Lemierre's disease appears to be increasing, perhaps due to ignorance of the disease by many clinicians, and diagnosis is often delayed with potentially fatal consequences.

Here we investigate the effect of emodin, an anthraquinone derivative isolated from rhubarb using a mouse silicosis model and in vitro cultured human macrophages and alveolar epithelial cells. Results from histological examination indicated that emodin reduced the degree of alveolitis and fibrosis in the lungs of mice exposed to silica particles. We also demonstrated that emodin effectively inhibited the phosphorylation of Smad3 and NF-κB and reduced the levels of inflammatory factors in the lung tissue of mice treated with silica particles. In addition, we found that emodin inhibited apoptosis and demonstrated an anti-fibrotic effect by down-regulating the pro-apoptotic protein Bax and up-regulating the anti-apoptotic protein Bcl-2. Furthermore, emodin increased E-cadherin levels, reduced the expression of Vimentin, α-SMA and Col-I, as well as pro-inflammatory factors TGF-β1, TNF-α and IL-1β in vivo and in vitro. These results suggested that emodin can regulate epithelial-mesenchymal transition (EMT) through the inhibition of the TGF-β1/Smad3 signaling pathway and the NF-κB signaling pathway to prevent alveolar inflammation and apoptotic process. Overall, this study showed that emodin can alleviate pulmonary fibrosis in silicosis through regulating the inflammatory response and fibrotic process at multiple levels.Cordycepin (CRD), an adenosine analog derived from traditional Chinese medicine, is an active component in Cordyceps militaris. It has been shown to have many protective effects during liver injury and ameliorate liver disease progression, but little is known about its effect on non-alcoholic fatty liver disease (NAFLD). This study aims to explore the effects of CRD on obesity-induced NAFLD. In this experiment, C57BL/6 J mice were randomly assigned into normal control group (NC), high fat diet group (HFD) and HFD + CRD group for 8 weeks. The body weights were recorded weekly, at the end of the experiments, the liver and serum samples were collected. We found that CRD administration reduced body weight and decreased the weight of adipose and liver, and CRD relieved liver injure through diminishing of histopathological changes and decreasing serum levels of AST, ALT, TG, TC, LDL-C and increased the level of HDL-C. Furthermore, treatment with CRD significantly alleviated expression of inflammatory factors (TNF-α, IL-6 and Il-1β) and macrophage markers (MCP1, MIP2, mKC and VCAM1). On the other hand, compared with HFD group, the CRD treated group markedly down-regulated relative proteins of lipid anabolism (SREBP1-c, ACC, SCD-1, LXRα and CD36) and up-regulated relative proteins of β-oxidation (p-AMPK, AMPK, CPT-1 and PPARα). LY2780301 In summary, our results suggest that CRD can be a potential therapeutic agent in the prevention and treatment of NAFLD, which may be closely related to its effect on lipid metabolism and inflammatory responses.
There are no publicly available national data on healthcare worker infections in Australia. It has been documented in many countries that healthcare workers (HCW) are at increased occupational risk of COVID-19. We aimed to estimate the burden of COVID-19 on Australia HCW and the health system by obtaining and organizing data on HCW infections, analyzing national HCW cases in regards to occupational risk and analyzing healthcare outbreak.

We searched government reports and websites and media reports to create a comprehensive line listing of Australian HCW infections and nosocomial outbreaks between January 25
and July 8
, 2020. A line list of HCW related COVID-19 reported cases was created and enhanced by matching data extracted from media reports of healthcare related COVID-19 relevant outbreaks and reports, using matching criteria. Rates of infections and odds ratios (ORs) for HCW were calculated per state, by comparing overall cases to HCW cases. To investigate the sources of infection amongst HCW, tare at greater risk of infection than the general community and nosocomial outbreaks can have substantial effects on workforce capacity by the quarantine of numerous HCW during an outbreak. The occurrence of hospital outbreaks even when community incidence was low highlights the high risk setting that hospitals present. Australia faced a resurgence of COVID-19 after the study period, with multiple hospital outbreaks. We recommend formal reporting of HCW infections, testing protocols for nosocomial outbreaks, cohorting of workforce to minimize the impact, and improved PPE guidelines to provide precautionary and optimal protection for HCW.
