and Risk Factors Study 2019 (GBD 2019) provided systematic estimates of incidence, morbidity, and mortality to inform local and international efforts toward reducing cancer burden. OBJECTIVE To estimate cancer burden and trends globally for 204 countries and territories and by Sociodemographic Index (SDI) quintiles from 2010 to 2019. EVIDENCE REVIEWThe GBD 2019 estimation methods were used to describe cancer incidence, mortality, years lived with disability, years of life lost, and disability-adjusted life years (DALYs) in 2019 and over the past decade. Estimates are also provided by quintiles of the SDI, a composite measure of educational attainment, income per capita, and total fertility rate for those younger than 25 years. Estimates include 95% uncertainty intervals (UIs).FINDINGS In 2019, there were an estimated 23.6 million (95% UI, 22.2-24.9 million) new cancer cases (17.2 million when excluding nonmelanoma skin cancer) and 10.0 million (95% UI, 9.36-10.6 million) cancer deaths globally, with an estimated 250 million (235-264 million) DALYs due to cancer. Since 2010, these represented a 26.3% (95% UI, 20.3%-32.3%) increase in new cases, a 20.9% (95% UI, 14.2%-27.6%) increase in deaths, and a 16.0% (95% UI, 9.3%-22.8%) increase in DALYs. Among 22 groups of diseases and injuries in the GBD 2019 study, cancer was second only to cardiovascular diseases for the number of deaths, years of life lost, and DALYs globally in 2019. Cancer burden differed across SDI quintiles. The proportion of years lived with disability that contributed to DALYs increased with SDI, ranging from 1.4% (1.1%-1.8%) in the low SDI quintile to 5.7% (4.2%-7.1%) in the high SDI quintile. While the high SDI quintile had the highest number of new cases in 2019, the middle SDI quintile had the highest number of cancer deaths and DALYs. From 2010 to 2019, the largest percentage increase in the numbers of cases and deaths occurred in the low and low-middle SDI quintiles. CONCLUSIONS AND RELEVANCEThe results of this systematic analysis suggest that the global burden of cancer is substantial and growing, with burden differing by SDI. These results provide comprehensive and comparable estimates that can potentially inform efforts toward equitable cancer control around the world.
Background: Pneumonia is the most common cause of community-acquired infection requiring ICU admission. 60-87% of patients with severe community acquired pneumonia (CAP) admitted to the ICU develops respiratory failure and require mechanical ventilation (MV). Objectives: To assess the efficacy and safety of adjunctive low dose hydrocortisone infusion treatment in Egyptian ICU patients with CAP. Methods: Hospitalized patients, clinically and radiologically diagnosed with CAP, were randomized to receive hydrocortisone 12.5 mg/h IV infusion for 7 days or placebo, along with antibiotics. The end-points of the study were improvement in PaO2:FIO2 (PaO2:FIO2 > 300 or ≥100 increase from study entry) and SOFA score by study day 8 and the development of delayed septic shock. Results: 80 patients were recruited, 40 of them received hydrocortisone and the remaining 40 received placebo. By study day 8, hydrocortisone treated patients showed a significant improvement in PaO2:FIO2 and chest radiograph score, and a significant reduction in C-reactive protein (CRP) levels, Sepsis-related Organ Failure Assessment (SOFA) score, and delayed septic shock compared to the control group. Hydrocortisone treatment was associated with a significant reduction in the duration of MV. However, hydrocortisone infusion did not show significant difference in the ICU mortality. Conclusions: adjunctive 7-day course of low dose hydrocortisone IV in patients with CAP hastens recovery of pneumonia and prevents the development of sepsis related complications with a significant reduction in duration of the mechanical ventilation
Background and objective: Many trace elements play important roles in activating or inhibiting enzymatic reactions, by competing with other elements and metalloproteins for binding sites, by affecting the permeability of cell membranes and by other mechanisms. They play important roles in the oxidant/ antioxidant balance. As such, trace elements are thought to be involved directly or indirectly in the pathogenesis of several diseases.The aim of the present study is to investigate the effect trace elements (Se, Mn and Zn) intravenously administered on the period the COPD patients spend on mechanical ventilation. Methods: In a randomized double-blinded controlled trial a set of 120 subjects (40 normal volunteers and 80 COPD) were recruited. Serum concentration levels of Se, Mn and Zn were determined for all enrolled subjects with Inductively Coupled Plasma spectroscopy. COPD patients received intravenous supplementation of the above trace elements and the period the patients spent on mechanical ventilation was determined.Results: There was a significant reduction (P = 0.013) in the period the patients with COPD spent on the mechanical ventilation when received intravenous supplementation (9.4 Ϯ 7.3 days) compared with the COPD patients who received placebo (17.8 Ϯ 7.6 days). Conclusions: Trace element (Se, Mn and Zn) status is altered in critically ill patients with COPD. The supplementation achieved a reduction in the period those patients spent on the mechanical ventilation. A larger multi-centre trial is required to confirm this preventive effect and to explore its applicability to other critical care conditions.
Salbutamol patches were prepared and evaluated. The effect of different Eudragits and various plasticizers on the properties of the patches were studied. Patches were prepared by casting method employing different plasticizers. These patches were evaluated for weight, thickness uniformity, swelling index, tensile strength, elongation percent and moisture absorption capacity. Release was studied. Tensile strength of the patches using Eudragit RS 100 as well as RS100 + L100 and triacetin was the lowest. Formulae containing 10% oleic acid and 5% dimethyl formamide, respectively, showed the highest permeability. These two formulae were studied clinically, the first formula only showed a significant improvement.
