Abstract BackgroundSo far, no research about the burden of the incidence rate, Disability-Adjusted Life Years (DALYs), and death rate associated with nasopharyngeal carcinoma (NPC) has been reported on the global, regional, and national levels. In this paper, we provide an overview of the most recent global epidemiology of nasopharyngeal cancer with data obtained from the Global Health Data Exchange (GHDx) repository.MethodsWe utilized the reports of the Global Burden of Diseases (GBD), Injuries, and Risk Factors Study in 2017 to estimate the burden of NPC in 194 countries and territories by age, sex, and Socio-Demographic Index (SDI) from 2007 to 2017. Moreover, we assessed the risk factors of NPC-related DALYs and deaths through the Comparative Risk Assessment Framework.ResultsIn the year 2017, 10.978 million new NPC cases with a 95% uncertainty interval of 10.444 to 11.556 million were recorded globally, whereas the DALYs and deaths were 2.09 million cases with a 95%UI 2 to 2.17 million and 695.5 thousand cases with 95% UI 668.7 to 722.7 thousand, respectively. From 2007 to 2017, the estimated incidence rate of NPC decreased by 2.3% with 95% uncertainty interval -7% to 3.28%, the estimated DALY rate decreased by 4.95% with 95% uncertainty interval from -8.46% to -1.24%, and the estimated death rate decreased by 3.01% with 95% uncertainty interval -6.36% to 0.43%. The age-standardized incidence, DALY, and death rates in 2017 were all the highest among the countries located in the middle-SDI quintiles region. At the GBD regional level, the most severe age-standardized incidence, DALY, and death rates in 2017 occurred in Oceania, followed by Southeast Asia and East Asia. From 2007 to 2017, the Caribbean and South Asia have the most increase in percentage in age-standardized incidence, DALY, and death rates. At the national level, countries like Ukraine, Jamaica, and the Dominican Republic reported the largest percentage increases in the age-standardized incidence, DALY, and death rates in a decade. From 2007 to 2017, DALYs and death rate of NPC increased by 18.99% (95%UI:13.34% - 25.73%) and 23.5% (95%UI:17.76% - 29.84%), respectively. While the estimated age-standardized attributable risk DALY rate and the age-standardized attributable risk mortality rate decreased by 5.55% (95% UI: -9.93% - 0.34%) and 4.25% (95% UI: -8.64% - 0.56%). ConclusionThe middle-SDI quintiles had the highest age-standardized incidence, DALY, and death rates in 2017. The largest increases in age-standardized incidence, DALY, and death rates were reported in the Caribbean and South Asia from 2007 to 2017, especially in countries such as Ukraine, Jamaica, Dominican Republic, and Dominica. In these regions, Alcohol consumption, Smoking, and A diet short of fruits were the primary three risk factors contributing to both DALYs and deaths in 2017.

IntroductionThe current study determined the level and trends associated with the incidence, death and disability rates for bladder cancer and its attributable risk factors in 204 countries and territories, from 1990 to 2019, by age, sex and sociodemographic index (SDI; a composite measure of sociodemographic factors).MethodsVarious data sources from different countries, including vital registration and cancer registries were used to generate estimates. Mortality data and incidence data transformed to mortality estimates using the mortality to incidence ratio (MIR) were used in a cause of death ensemble model to estimate mortality. Mortality estimates were divided by the MIR to produce incidence estimates. Prevalence was calculated using incidence and MIR-based survival estimates. Age-specific mortality and standardised life expectancy were used to estimate years of life lost (YLLs). Prevalence was multiplied by disability weights to estimate years lived with disability (YLDs), while disability-adjusted life years (DALYs) are the sum of the YLLs and YLDs. All estimates were presented as counts and age-standardised rates per 100 000 population.ResultsGlobally, there were 524 000 bladder cancer incident cases (95% uncertainty interval 476 000 to 569 000) and 229 000 bladder cancer deaths (211 000 to 243 000) in 2019. Age-standardised death rate decreased by 15.7% (8.6 to 21.0), during the period 1990–2019. Bladder cancer accounted for 4.39 million (4.09 to 4.70) DALYs in 2019, and the age-standardised DALY rate decreased significantly by 18.6% (11.2 to 24.3) during the period 1990–2019. In 2019, Monaco had the highest age-standardised incidence rate (31.9 cases (23.3 to 56.9) per 100 000), while Lebanon had the highest age-standardised death rate (10.4 (8.1 to 13.7)). Cabo Verde had the highest increase in age-standardised incidence (284.2% (214.1 to 362.8)) and death rates (190.3% (139.3 to 251.1)) between 1990 and 2019. In 2019, the global age-standardised incidence and death rates were higher among males than females, across all age groups and peaked in the 95+ age group. Globally, 36.8% (28.5 to 44.0) of bladder cancer DALYs were attributable to smoking, more so in males than females (43.7% (34.0 to 51.8) vs 15.2% (10.9 to 19.4)). In addition, 9.1% (1.9 to 19.6) of the DALYs were attributable to elevated fasting plasma glucose (FPG) (males 9.3% (1.6 to 20.9); females 8.4% (1.6 to 19.1)).ConclusionsThere was considerable variation in the burden of bladder cancer between countries during the period 1990–2019. Although there was a clear global decrease in the age-standardised death, and DALY rates, some countries experienced an increase in these rates. National policy makers should learn from these differences, and allocate resources for preventative measures, based on their country-specific estimates. In addition, smoking and elevated FPG play an important role in the burden of bladder cancer and need to be addressed with prevention programmes.

Abstract Introduction: Breast cancer is the most common cancer in women worldwide. However, no comprehensive study has been conducted to compare the incidence, mortality, and disability-adjusted life years (DALYs) for female breast cancer among different countries. The current study examined the level and trends of incidence, death, and DALYs for breast cancer and its attributable risk factors among women in 195 countries from 1990 to 2017 by age, socio-demographic index (SDI; a composite of socio-demographic factors), and healthcare access and quality (HAQ; an indicator of health system performance) index.Methods: Vital registration, verbal autopsy, and cancer registries were used across the globe to generate estimates. Incidence, mortality, and DALYs were estimated. All estimates are presented as counts and age-standardised rates per 100,000 person-years. Results: Between 1990 and 2017 the global incidence of breast cancer increased significantly by 17.1% (95% uncertainty interval [UI]: 7.1–23.6; with 1.9 million incidences in 2017 [95% UI 1.9–2.0]; age-standardised rate of 45.9 [95% UI: 44.2–47.4]). However, over this same period the age-standardised death rate significantly decreased by 10.6% (95% UI: -19.5 to -4.4), with 600.7 thousand deaths in 2017 (95% UI: 578.7–630.0; age-standardised death rate of 14.1 95% UI: 13.6–14.8). Global DALYs also significantly decreased between 1990 and 2017 by 9.3% (95% UI: -19.9 to -1.6) with 17.4 million DALYs reported in 2017 (95% UI: 16.6–18.4; age-standardised rate of 414.7; 95% UI: 395.5– 437.6). Lebanon [138.3 (95% UI: 106.5–170.7)], the Netherlands [109.8 (95% UI: 97.4–122.7)], and the UK [102.6 (95% UI: 99.6–105.8)] had the three highest age-standardised incidence rates in 2017. Meanwhile, Pakistan [34.1 (95% UI: 20.9–71.3)], Tonga [34.0 (95% UI: 26.8–41.9)], and the Bahamas [33.3 (95% UI: 28.9–37.8)] had the three highest age-standardised death rates in 2017. Between 1990 and 2017, Saudi Arabia [232% (95% UI: 93–410)], Mauritius [174% (95% UI: 134–222)], and Taiwan [172% (95% UI: 141–208)] showed an increasing trend for the highest age-standardised incidence rate of breast cancer. Meanwhile, Mauritius [90% (95% UI: 66–117)], Philippines [76% (95% UI: 43–115)], and the Dominican Republic [69% (95% UI: 11–125)] produced the greatest significant increasing trend in age-standardised death rates. An increasing trend between population ageing and age-standardised incidence and death rates were observed globally, peaking among the oldest population grouping [incidence: 535.6 (95% UI: 511.8–560.7); death: 251.4 (95% UI: 242.6–260.9)]. Non-linear associations were observed between age-standardised DALY rates with SDI and HAQ. Alcohol consumption [9.2% (95% UI: 7.7–10.7)], high fasting plasma glucose [6.1% (95% UI: 1.1–13.6)], and high body mass index [4.5% (95% UI: 1.4–8.5)] were the three largest contributors to breast cancer DALYs globally.Conclusions: Remarkable inter-country variation exists in the burden of breast cancer. While there is a global downward trend in breast cancer age-standardised mortality rates, some countries are experiencing increases in age-standardised incidence and death rates from breast cancer. Prevention measures should be tailored to national-level estimates specific for each country and strengthened through early detection and treatment and public policy awareness campaigns aimed to reduce exposure to modifiable risk factors, particularly for countries with high incidence levels and/or increasing trends.

Abstract Background Kidney cancer’s incidence and mortality vary in different regions and countries. To compare and interpret kidney cancer’s burden and change trends in the globe and in different countries, we conducted this study to report the global kidney cancer burden and attributable risk factors. Methods Data about kidney cancer’s incidence, death, disability-adjusted life-year (DALY) were extracted from the Global Burden of Diseases 2017. Besides, social-demographic index (SDI) values were adopted to investigate the correlation between kidney cancer’s burden and social development degrees. Results In the globe, the incidence case of kidney cancer increased sharply from 207.31*103 in 1990 to 393.04*103 in 2017. High SDI countries had the highest kidney cancer’s burden with a decreased trend in incidence rate. On the contrary, the incidence rate was rapidly increased in low-middle SDI countries, although their burden of kidney cancer kept relatively low. At the same time, the deaths of kidney cancer increased from 68.14*103 to 138.53*103, and the kidney cancer-related DALYs increased from 1915.49*103 in 1990 to 3284.32*103 in 2017. Then, we searched the GBD database for kidney cancer-related risk factor. The high body-mass index and smoking were the main factors contributing to kidney cancer-related mortality. Conclusions Generally, from 1990 to 2017, the incidence rate in developed countries had gone down from the historic peak values while the incidence rate was still on the rise in developing counties. Given the aging trend in the globe, it is necessary to appeal to the public to decrease the exposure of kidney cancer-associated risk factors.

The Impact

BACKGROUND The impact of climate temperature on the counts (number of positive COVID-19 cases reported), recovery, and death rates of COVID-19 cases in South Africa's nine provinces was investigated. The data for confirmed cases of COVID-19 were collected for March 25 and June 30, 2020 (14 weeks) from South Africa's Government COVID-19 online resource, while the daily provincial climate temperatures were collected from the website of the South African Weather Service. Our result indicates that a higher or lower climate temperature does not prevent or delay the spread and death rates but shows significant positive impacts on the recovery rates of COVID-19 patients. Thus, it indicates that the climate temperature is unlikely to impose a strict limit on the spread of COVID-19. There is no correlation between the cases and death rates, an indicator that no particular temperature range is closely associated with a faster or slower death rate of COVID-19 patients. As evidence from our study, a warm climate temperature can only increase the recovery rate of COVID-19 patients, ultimately impacting the death and active case rates and freeing up resources quicker to enable health facilities to deal with those patients' climbing rates who need treatment. OBJECTIVE This study aims to investigate the impact of climate temperature variation on the counts, recovery, and death rates of COVID-19 cases in all South Africa's provinces. The findings were compared with those of countries with comparable climate temperature values. METHODS The data for confirmed cases of COVID-19 were collected for March 25 and June 30 (14 weeks) for South African provinces, including daily counts, death, and recovery rates. The dates were grouped into two, wherein weeks 1-5 represent the periods of total lockdown to contain the spread of COVID-19 in South Africa. Weeks 6-14 are periods where the lockdown was eased to various levels 4 and 3. The daily information of COVID-19 count, death, and recovery was obtained from South Africa's Government COVID-19 online resource (https://sacoronavirus.co.za). Daily provincial climate temperatures were collected from the website of the South African Weather Service (https://www.weathersa.co.za). The provinces of South Africa are Eastern Cape, Western Cape, Northern Cape, Limpopo, Northwest, Mpumalanga, Free State, KwaZulu-Natal, Western Cape, and Gauteng. Weekly consideration was given to the daily climate temperature (average minimum and maximum). The recorded values were considered, respectively, to be in the ratio of death-to-count (D/C) and recovery-to-count (R/C). Descriptive statistics were performed for all the data collected for this study. The analyses were performed using the Person’s bivariate correlation to analyze the association between climate temperature, death-to-count, and recovery-to-count ratios of COVID-19. RESULTS The results showed that higher climate temperatures aren't essential to avoid the COVID-19 from being spread. The present results conform to the reports that suggested that COVID-19 is unlike the seasonal flu, which does dissipate as the climate temperature rises [17]. Accordingly, the ratio of counts and death-to-count cannot be concluded to be influenced by variations in the climate temperatures within the study areas. CONCLUSIONS The study investigates the impact of climate temperature on the counts, recovery, and death rates of COVID-19 cases in all South Africa's provinces. The findings were compared with those of countries with comparable climate temperatures as South Africa. Our result indicates that a higher or lower climate temperature does not prevent or delay the spread and death rates but shows significant positive impacts on the recovery rates of COVID-19 patients. Warm climate temperatures seem not to restrict the spread of the COVID-19 as the count rate was substantial at every climate temperatures. Thus, it indicates that the climate temperature is unlikely to impose a strict limit on the spread of COVID-19. There is no correlation between the cases and death rates, an indicator that there is no particular temperature range of the climatic conditions closely associated with a faster or slower death rate of COVID-19 patients. However, other shortcomings in this study's process should not be ignored. Some other factors may have contributed to recovery rates, such as the South African government's timely intervention to announce a national lockout at the early stage of the outbreak, the availability of intensive medical care, and social distancing effects. Nevertheless, this study shows that a warm climate temperature can only help COVID-19 patients recover more quickly, thereby having huge impacts on the death and active case rates.

Coronary heart disease is a common, highly lethal, disease which frequently attacks without warning and too often presents with sudden death as the first symptom. Chances of an American male developing CHD before age 60 are one in five.Most angina, infarctions and sudden deaths represent medical failures which should have been forecasted and prevented. About 30% of first MI's will shortly develop angina and experience a per annum death rate, half of which will be sudden deaths. Reinfarctions will occur at 6% per year and half the recurrences will be fatal.No major innovations are needed to identify coronary candidates or to establish their risk from the joint effect of known risk factors. However, all have much to learn about motivating changes in behavior required to control the major risk factors such as cigarette smoking, faulty diet, overweight, sedentary living, abnormal lipids, hypertension and impaired glucose tolerance.Low density lipoprotein cholesterol promotes atherogenesis whereas HDL-cholesterol is protective, and the net effect is judged by their ratio. Hypertension, systolic or diastolic, labile or fixed, at any age in either sex is a powerful contributor to CHD. The impact of diabetes is greater for women, diminishes with age and varies depending on coexisting risk factors.Optimal risk evaluation requires quantitative combination of risk factors so as to include persons with multiple marginal risk factor abnormalities who are at high risk.

Abstract Background Hemodialysis patients with COVID-19 have been reported to be at higher risk for death than the general population. Several prognostic factors have been identified in the studies from Asian, European or American countries. This is the first national Lebanese study assessing the factors associated with SARS-CoV-2 mortality in hemodialysis patients. Methods This is an observational study that included all chronic hemodialysis patients in Lebanon who were tested positive for SARS-CoV-2 from 31st March to 1st November 2020. Data on demographics, comorbidities, admission to hospital and outcome were collected retrospectively from the patients’ medical records. A binary logistic regression analysis was performed to assess risk factors for mortality. Results A total of 231 patients were included. Mean age was 61.46 ± 13.99 years with a sex ratio of 128 males to 103 females. Around half of the patients were diabetics, 79.2% presented with fever. A total of 115 patients were admitted to the hospital, 59% of them within the first day of diagnosis. Hypoxia was the major reason for hospitalization. Death rate was 23.8% after a median duration of 6 (IQR, 2 to 10) days. Adjusted regression analysis showed a higher risk for death among older patients (odds ratio = 1.038; 95% confidence interval: 1.013, 1.065), patients with heart failure (odds ratio = 4.42; 95% confidence interval: 2.06, 9.49), coronary artery disease (odds ratio = 3.27; 95% confidence interval: 1.69, 6.30), multimorbidities (odds ratio = 1.593; 95% confidence interval: 1.247, 2.036), fever (odds ratio = 6.66; 95% confidence interval: 1.94, 27.81), CRP above 100 mg/L (odds ratio = 4.76; 95% confidence interval: 1.48, 15.30), and pneumonia (odds ratio = 19.18; 95% confidence interval: 6.47, 56.83). Conclusions This national study identified older age, coronary artery disease, heart failure, multimorbidities, fever and pneumonia as risk factors for death in patients with COVID-19 on chronic hemodialysis. The death rate was comparable to other countries and estimated at 23.8%.
