The aim of this study was to evaluate the correlation between several ocular parameters (intraocular pressure [IOP], corneal biomechanical properties) and the visual field (VF) mean deviation (VF MD) in eyes with open-angle glaucoma (OAG).

We conducted a cross-sectional, observational study in which we measured the IOP with Goldmann applanation tonometry, the central corneal thickness (CCT), and the corneal parameters obtained from the Ocular Response Analyzer® (ORA®) and the Corvis® ST non-contact tonometer, in newly diagnosed and treatment-naïve eyes with OAG, to investigate whether there was any correlation between these ocular parameters and the VF MD.

A total of 51 eyes were analyzed. A statistically significant correlation was found only between the VF MD and corneal hysteresis (CH) (P = 0.003, r
 = 0.16) and CCT (P = 0.03, r
 = 0.08).

These results demonstrate that CH and CCT are associated with the amount of VF damage in treatment-naïve OAG eyes.
These results demonstrate that CH and CCT are associated with the amount of VF damage in treatment-naïve OAG eyes.People's ability to critically assess cancer-related information is essential from a preventional and therapeutic, as well as a general democratic perspective. Such cancer literacy is not just about acquiring factual knowledge. It also involves the ability to analyze how the information is contextualized-how cancer is framed. Previous research concerning the framing of cancer in public discourse is voluminous and penetrating but also fragmented and inaccessible to non-experts. In this study, we have developed an integrated and applicable tool for analyzing cancer discourse by systematically classifying distinctive ways of framing of the concept of cancer. Building on previous research and an inductive framing analysis of a broad range of public cancer discourse, systematically selected from British and Norwegian newspapers, we have characterized nine cancer frames the biomedical, the environmental, the epidemiological, the personal, the sociopolitical, the economic, the antagonistic, the alternative, and the symbolic frame. This framing scheme may be applied to analyze cancer-related discourse across a plurality of themes and contexts. We also show how different frames combine to produce more complex messages, thereby revealing underlying patterns, strategies, and conflicts in cancer communication. In conclusion, this analytical tool enables critical reading of cancer-related information and may be especially useful in educational initiatives to advance health communication and public understanding of cancer.
Intravenous lipid emulsions (ILE) have been credited for successful resuscitation in drug intoxication cases where other cardiac life-support methods have failed. However, inter-individual variability can function as a confounder that challenges our ability to define the scope of efficacy for lipid interventions, particularly as relevant data are scarce. To address this challenge, we developed a quantitative systems pharmacology model to predict outcome variability and shed light on causal mechanisms in a virtual population of rats subjected to bupivacaine toxicity and ILE intervention.

We combined a physiologically based pharmacokinetic-pharmacodynamic model with data from a small study in Sprague-Dawley rats to characterize individual-specific cardiac responses to lipid infusion. We used the resulting individual parameter estimates to posit a population distribution of responses to lipid infusion. On that basis, we constructed a large virtual population of rats (N=10,000) undergoing lipid therapy followmplex, dynamic physiological outcomes over a virtual population. Despite being informed by very limited data, our mechanistic model predicted a plausible range of treatment outcomes that accurately predicts changes in LD50 when extrapolated to putatively toxic doses of bupivacaine. Furthermore, causal analysis of the predicted survival outcomes indicated a critical synergy between scavenging and direct cardiotonic mechanisms of ILE action.There have been recent encouraging reports about the development of vaccines for COVID-19. Given the scale and effects of this pandemic on public health and economies worldwide, there has been an unprecedented approach across the globe, leading to the emergence of vaccine candidates many times faster than the normal process would allow. This review gives up-to-date information as of November 28, 2020, on the latest developments in this area and covers the plans to roll out the most promising vaccines across the entire world to halt the spread of this devastating virus.The exaggerated host response to Sars-CoV-2 plays an important role in COVID-19 pathology but provides a therapeutic opportunity until definitive virus targeted therapies and vaccines become available. Given a central role of endothelial dysfunction and systemic inflammation, repurposing ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), statins, and aspirin has been of interest. In this retrospective, single-center study, we evaluated the primary outcomes of mortality and ICU admission in 587 hospitalized patients with documented COVID-19 with or without ACEIs, ARBs, statins, and aspirin. Atorvastatin was associated with reduced mortality, which persisted after adjusting for age, lockdown status, and other medications (OR 0.18. 95% CI 0.06-0.49, P = 0.001). ACEIs were also associated with reduced mortality in the crude model (OR 0.20, CI 0.06-0.66, P = 0.008), as ACEIs and ARBs were combined as a single group (OR 0.35, CI 0.16-0.75, P = 0.007), although ARBs alone did not reach statistical significance. There was no association between any medications and risk of ICU admission. Aspirin only achieved a significant association of reduced mortality in a subgroup of patients with diabetes in the crude model (OR 0.17, CI 0.04-0.80, P = 0.02). The reduced mortality observed with atorvastatin is consistent with other literature, and consideration should be given to atorvastatin as a COVID-19 treatment. While there was suggested benefit of ACEIs and ARBs in the present study, other studies are varied and further studies are warranted to recommend employing these medications as a treatment strategy. Nevertheless, this study combined with others continues to give credibility that ACEIs and ARBs are safe to continue in the setting of COVID-19.COVID-19 is now pandemic throughout the world, and scientists are searching for effective therapies to prevent or treat the disease. The combination of curcumin and piperine is a potential option for the management of COVID-19 based on several mechanisms including antiviral, anti-inflammatory, immunomodulatory, antifibrotic, and antioxidant effects. Here, we describe the probable mechanism of curcumin-piperine against COVID-19. Administration of curcumin-piperine combination appears as a potential strategy to counterbalance the pathophysiological features of COVID-19 including inflammation. The optimal dose and duration of curcumin-piperine supplementation should be determined in the future.COVID-19 is a pandemic and acute respiratory disease. Every day, all around the world, researchers are endeavoring to find effective or potential adjuvant therapies. Studies illustrate that essential oils from cinnamon and derivatives such as cinnamaldehyde and cinnamic acid possess numerous biological activities. In this paper, we have reviewed the possible mechanisms of cinnamon on the inflammatory cascade as a potential alternative therapy to decrease oxidative stress and inflammation in COVID-19 patients.With the largest viral loads in both symptomatic and asymptomatic patients with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) present in the oral and nasal cavities, agents that act on these two areas have the potential for large therapeutic and prophylactic benefit. A literature review was conducted to elucidate the possible agents useful in treatment of SARS-CoV-2. These agents were evaluated for their current applications, adverse reactions, their current state of study, and any future considerations in their management of coronavirus disease 2019 (COVID-2019). Our review has found that, while there are many promising agents with proven efficacy in their in-vitro efficacy against SARS-CoV-2, more clinical trials and in-vivo studies, as well as safety trials, must be conducted before these agents can be effectively implemented.In COVID-19 infection, a balance must be achieved in immune defence against the virus without precipitating a cytokine storm, which is responsible for lung injury and respiratory distress in severe cases. The initial immune response and the subsequent resolution of inflammation are likely to be dependent on nutritional status, as one contributing factor. Here, we have reviewed the potential link between two specific nutrients, coenzyme Q10 (CoQ10) and selenium, with effects on oxidative stress and inflammation in viral infection. We conclude that both reagents show promise in the treatment of patients with COVID-19 disease. This could give particular relevance over the next several months as promising vaccines are deployed to minimise the COVID-19 spread and as a potential preventative or mitigating approach for future epidemics and pandemics.Recent investigations are seeking a novel treatment to control the new pandemic of coronavirus 19 (COVID-19). The aim of this systematic review was to study the effect of ozone therapy on COVID-19 patients and the available supporting evidence. Electronic databases including MEDLINE (via PubMed), EMBASE, Cochrane Library (CENTRAL), and TRIP, clinical trial registries, and preprint sources were searched for published evidence-based articles. Y-27632 price In addition, manual searching was conducted for articles published up to April 6, 2020, using MeSH and free text keywords with no language limitation. Articles were screened, categorized, and extracted for relative data. Data were reported in a descriptive manner. Among 234 articles, 9 were selected for review of the inclusion criteria. No published original articles were found regarding the efficacy of ozone therapy on COVID-19. Five review studies were found in which the potential role of systemic ozone therapy was concluded to be effective in controlling COVID-19 because of its antiviral, oxygenation, anti-inflammatory, oxidation balancing, and immunomodulation effects. Three ongoing clinical trials were registered in China. A preliminary report of an ongoing study in Italy on 46 patients (11 intubated and 35 non-intubated) showed that in 39 (84%) of the patients, an improvement was seen. In spite of the promising background data, as well as the expert opinions and a preliminary report indicating the effectiveness of ozone, there is still not enough evidence to confirm this as a viable treatment option for COVID-19.Background and aims Non-contrast chest computed tomography (CT) scanning is one of the important tools for evaluating of lung lesions. The aim of this study was to use a deep learning approach for predicting the outcome of patients with COVID-19 into two groups of critical and non-critical according to their CT features. Methods This was carried out as a retrospective study from March to April 2020 in Baqiyatallah Hospital, Tehran, Iran. From total of 1078 patients with COVID-19 pneumonia who underwent chest CT, 169 were critical cases and 909 were non-critical. Deep learning neural networks were used to classify samples into critical or non-critical ones according to the chest CT results. Results The best accuracy of prediction was seen by the presence of diffuse opacities and lesion distribution (both=0.91, 95% CI 0.83-0.99). The largest sensitivity was achieved using lesion distribution (0.74, 95% CI 0.55-0.93), and the largest specificity was for presence of diffuse opacities (0.95, 95% CI 0.9-1). The total model showed an accuracy of 0.
