    Cardiotoxicity is the major challenge in chemotherapy with doxorubicin (DOX) or adriamycin. Doxorubicin manifests oxidative stress via an uncontrolled progression of reactive oxygen species in cardiomyocytes; thereby, dysregulation and dysfunction of myocardium thus lead to apoptosis. Several attempts have been made to overcome this side effect in patients with antioxidant-rich supplements to control the free radicals. Plant-based or plant-derived compounds pay more attention to cure such complications in patients for supporting the treatment, revitalizing or regulating the normal metabolism. Hence, our study focused on pretreatment of embryonically derived rat cardiomyocytes (H9c2) with phytocompound lotusine to prevent DOX-mediated oxidative stress. From the experiment, the DOX-exposed cells have shown morphological abnormalities such as reduced cell size, shrinkage, blebbing, and chromatin condensation, whereas no such deformities were observed in lotusine-pretreated cells even after the exposure to DOX. Increased endogenous antioxidants with reduced lipid peroxidation were observed in lotusine-pretreated cells, whereas the antioxidants were reduced along with increased lipid peroxidation in doxorubicin-exposed cells. A decreased reactive oxygen species generation was evidenced with the 2′,7′-dichlorofluorescein diacetate (DCF-DA) staining method. In qPCR analysis, the lotusine-pretreated cells have mitigated doxorubicin-mediated apoptosis by downregulating the pro-apoptotic gene Bax and apoptotic executor caspase-3. It was further confirmed with the luminometric assay, which resulted in lesser luminescence in lotusine-pretreated cells, whereas higher luminescence was recorded in doxorubicin-alone-treated cells. In conclusion, the present study revealed that the lotusine pretreatment has exhibited potential cardioprotective activity against DOX-induced oxidative stress by increasing the intracellular antioxidant defense.Coronavirus disease 2019 (COVID-19) is a global pandemic infectious disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), and abnormal, overactivated innate immunity and “cytokine storms” have been proposed as potential pathological mechanisms for rapid COVID-19 progression. Theoretically, asthmatic patients should have increased susceptibility and severity for SARS-CoV-2 infection due to a deficient antiviral immune response and the tendency for exacerbation elicited by common respiratory viruses. However, existing studies have not shown an expected prevalence of asthmatic individuals among COVID-19 patients. Certain aspects of type 2 immune response, including type 2 cytokines (IL-4, IL-13, etc.) and accumulation of eosinophils, might provide potential protective effects against COVID-19. Furthermore, conventional therapeutics for asthma, including inhaled corticosteroids, allergen immunotherapy (AIT), and anti-IgE monoclonal antibody, might also reduce the risks of asthmatics suffering infection of the virus through alleviating inflammation or enhancing antiviral defense. The interactions between COVID-19 and asthma deserve further attention and clarification.Background Cervical cancer ranks fourth amongst the commonest malignancies worldwide and the second most prevalent cancer afflicting women in low-to-middle income countries (LMICs), hence, of great public health importance. Opaganib LMICs are the most affected regions as evidenced by their high prevalence of the disease. Mortality associated with cervical neoplasms is preventable through the implementation of recommended preventive approaches. Aims This review aimed to appraise evidence on the cost effectiveness of cervical cancer prevention interventions in LMICs involving cervical screening and human papilloma virus (HPV) vaccination programmes. Methods A search of CINAHL, MEDLINE, PubMed, and Web of Science was elicited and studies published between 1st January 2008 and 31st December 2018 were retrieved. Two authors independently undertook the screening, review, selection of studies, and data extraction with disagreements being resolved through discussion and consensus. Results Twelve studies were selected. The cost-effectiveness outcomes of HPV vaccination and screening interventions are dependent on age, screening method used, intervention coverage, and the number of doses or visits required for vaccination and screening, respectively. A combination of visual inspection with acetic acid (VIA) screening and HPV vaccination appears to be the most cost-effective approach in reducing the lifetime risk for HPV-linked cervical neoplasms. Similarly, vaccination as a stand-alone intervention is potentially cost effective provided the coverage is maintained between 70 and 100%. Conclusions HPV vaccination and screening interventions may be cost effective in LMICs and potentially reduce the lifetime risk, economic burden, and associated mortality. However, it is important to consider the factors that influence the cost effectiveness of cervical cancer prevention interventions for better outcomes to be realised.The fiscal regime implemented in Brazil with the constitutional amendment 95 (EC-95) of December 2016 froze primary expenditures for 20 years, including healthcare spending. Previous studies have estimated strong negative effects of this policy on the health of Brazilians. Although there has been a constant pressure to repeal EC-95, this policy is unlikely to be changed in the near future. Thus, there is also a need to take actions within its own terms in order to mitigate its harmful consequences on population health. Shedding light on the existing evidence about the impact of austerity on health, the present work discusses how decision-makers can use a formal framework of decision making in priority setting and resource allocation to tackle the amplified budgetary strain. Drawing on principles of Program Budgeting and Marginal Analysis (PBMA), efficiency can be improved by shifting spending from low-value to higher-value areas, avoiding the “across-the-board cut” caused by non-differential consideration of expenditures in a context of mismatched growth of demand and supply of healthcare. By evaluating opportunity costs of investment and disinvestment proposals on the basis of multiple criteria and marginal analysis, the Brazilian public healthcare system could obtain gains in value, achieving better performance and attenuating the relative decline in spending on health brought by an austerity scenario.
