Chemotherapy is the main treatment for acute myeloid leukemia (AML), but the therapeutic efficacy is modest, and most commonly manifests as relapse from remission. Thus, improving long-term AML survival is a crucial clinical challenge. In recent years, oncolytic virotherapy has provided an alternative approach for AML treatment. The use of oncolytic reoviruses has been explored in more than 30 clinical trials for safety and feasibility issues. However, like other oncolytic viruses, neutralizing antibodies (NAbs) reduce therapeutic efficacy. To tackle this problem, human umbilical cord mesenchymal stem cells (hUC-MSCs) were used to deliver reovirus using in vitro and in vivo models. Human UC-MSCs were successfully loaded with reovirus, without impairing biological function.We also observed in vitro protective effects of hUC-MSCs on reovirus in the presence of NAbs. In the immunocompromised AML mouse model, hUC-MSCs effectively carried reoviruses to tumor lesions and significantly prolonged the survival of AML xenografts in mice in the presence of a high titer anti-reovirus antibody (p = 0.001). However, reovirus-induced activation of AKT, stress-activated protein kinase/c-Jun N-terminal kinase (SAPK/JNK), and NF-κB signaling led to the maintenance of intrinsic migratory properties and secretion of pro-inflammatory cytokines from hUC-MSCs, particularly CXCL10. In immuno-competent AML mice, MSCs carrying reovirus triggered immune responses, and eventually inhibited tumor growth. Therefore, these results suggest that MSCs as carriers of oncolytic reoviruses can enhance the antitumor efficacy of virotherapy.Chronic obstructive pulmonary disease (COPD) is characterized by irreversible and progressive airflow limitation and encompasses varying degrees of chronic obstructive bronchitis and emphysema. Our previous study showed that Forkhead box protein A2 (FOXA2) is involved in cigarette smoke (CS)-induced squamous metaplasia. However, the contribution of FOXA2 activity to CS-induced cellular senescence and lung inflammation remains largely unknown. Here, we report that FOXA2 was underexpressed in CS-exposed mouse lungs, and decreased expression of FOXA2 was related to cell senescence and inflammation. Subsequent investigation suggested that FOXA2 is an anti-senescence factor in lung that is involved in inflammatory responses. Furthermore, FOXA2 overexpression delayed CSE-induced senescence and inflammation, which correlated with regulation of the p38 and Erk1/2 MAPK signaling pathways by CSE-induced FOXA2 downregulation. Collectivelly, these findings reveal a protective role for FOXA2 as a regulator of cell senescence and inflammation during COPD.COVID-19 pandemic has started in December 2019 in China and quickly extended to become a worldwide health and economic emergency issue. It is caused by the novel coronavirus; SARS-CoV-2. GSK-3 inhibitor review COVID-19 patients' clinical presentations vary from asymptomatic infection or flu like symptoms to serious pneumonia which could be associated with multiple organ failure possibly leading to death. It is understood that the immune response to SARS-CoV-2 includes all elements of the immune system which could altogether succeed in viral elimination and complete cure. Meanwhile, this immune response may also lead to disease progression and could be responsible for the patient's death. Many trials have been done recently to create therapies and vaccines against human coronavirus infections such as MERS or SARS, however, till now, there is some controversy about the effectiveness and safety of antiviral drugs and vaccines which have been developed to treat and prevent this disease and its management depends mainly on supportive care. The spike glycoprotein or protein S of SARS-CoV-2 is the main promoter that induces development of neutralizing antibodies; hence, many attempts of vaccines and antiviral drugs development have been designed to be directed specifically against this protein. While some of these attempts have been proved to be efficient in in vitro settings, only few of them have been proceeded to randomized animal trials and human studies which makes COVID-19 prevention an ongoing challenge. This review describes the natural immune response scenario during COVID-19 and the vaccines development trials to create efficient vaccines thus helping to build more effective approaches for prophylaxis and management.
Inpatient portals have been introduced into tertiary hospitals to meet patients' information and communication needs, to increase their awareness of health care, and to facilitate their transition after discharge. However, there is inadequate knowledge about hospitalised oncology patients' use and perceptions of these technologies.
To explore cancer patients' use and perceptions of an inpatient portal in a tertiary hospital and to identify the main benefits and barriers for patients in using the portal.
A qualitative case study was conducted in a tertiary hospital in Riyadh, Saudi Arabia. Only cancer patients were invited to participate. Twenty-two semi-structured interviews were conducted in the patient's room in a cancer care centre in January 2020. Interviews were audio-recorded, fully transcribed, and analysed using a thematic analysis method.
Most patients used the portal for the first time. The most used features were entertainment, watching fall prevention videos and viewing medication lists. Ain improving cancer patients' hospitalisation experience. It helped cancer patients to acquire knowledge about their own health, to actively engage in their care processes, and to request and acquire electronic services, in addition to providing entertainment. Future research on which factors inspire patients' use of the portal and how the influence is achieved is needed for the successful integration of the portal into the patients' hospital care process.
The lack of interoperability is one of the biggest obstacles to the complete digitalization of patient health information in electronic medical records (EMR). The high volume of data breaches has put pressure on care providers to adopt data protection measures to remain compliant with legal requirements. Extreme data protection measures can impede information flow, but they also instill confidence in secure information sharing. This study investigates how the adoption of security measures, privacy regulations, and communication standards has impacted patient health information interoperability at technical (TI), semantic (SI), and organizational (OI) levels within the hospitals.
The study utilizes a quasi-experimental research design to probe the relationships of interest. Secondary data from a survey of randomly selected 773 hospitals conducted by the European Commission in over 30 countries in Europe is used to understand the relationships. The study counters selection bias and accounts for systematic differences in adopting treatments of interest in the hospitals using the propensity score-based approaches for the observational data.
