Summary Background Ending the global tobacco epidemic is a defining challenge in global health. Timely and comprehensive estimates of the prevalence of smoking tobacco use and attributable disease burden are needed to guide tobacco control efforts nationally and globally. Methods We estimated the prevalence of smoking tobacco use and attributable disease burden for 204 countries and territories, by age and sex, from 1990 to 2019 as part of the Global Burden of Diseases, Injuries, and Risk Factors Study. We modelled multiple smoking-related indicators from 3625 nationally representative surveys. We completed systematic reviews and did Bayesian meta-regressions for 36 causally linked health outcomes to estimate non-linear dose-response risk curves for current and former smokers. We used a direct estimation approach to estimate attributable burden, providing more comprehensive estimates of the health effects of smoking than previously available. Findings Globally in 2019, 1·14 billion (95% uncertainty interval 1·13–1·16) individuals were current smokers, who consumed 7·41 trillion (7·11–7·74) cigarette-equivalents of tobacco in 2019. Although prevalence of smoking had decreased significantly since 1990 among both males (27·5% [26·5–28·5] reduction) and females (37·7% [35·4–39·9] reduction) aged 15 years and older, population growth has led to a significant increase in the total number of smokers from 0·99 billion (0·98–1·00) in 1990. Globally in 2019, smoking tobacco use accounted for 7·69 million (7·16–8·20) deaths and 200 million (185–214) disability-adjusted life-years, and was the leading risk factor for death among males (20·2% [19·3–21·1] of male deaths). 6·68 million [86·9%] of 7·69 million deaths attributable to smoking tobacco use were among current smokers. Interpretation In the absence of intervention, the annual toll of 7·69 million deaths and 200 million disability-adjusted life-years attributable to smoking will increase over the coming decades. Substantial progress in reducing the prevalence of smoking tobacco use has been observed in countries from all regions and at all stages of development, but a large implementation gap remains for tobacco control. Countries have a clear and urgent opportunity to pass strong, evidence-based policies to accelerate reductions in the prevalence of smoking and reap massive health benefits for their citizens.

The recent outbreak of the novel COVID-19 is posing a severe public health risk across the globe. The Kingdom of Saudi Arabia (KSA) is one of the greatest destinations of religious congregations of Muslims. One of the largest religious gatherings is the Hajj that is anticipated to produce serious challenges of mass level exposures and spread to every corner of the world. Therefore, it is highly recommended that the Ministry of Hajj and Umrah (KSA), must regularly analyze the prevailing situation of COVID-19, and involve the religious scholars to make appropriate decisions about Hajj 2020. Although the Saudi government has been continuously taking all possible measures to contain the pandemic, people's cooperation is crucial in the fight against COVID-19.
Service quality has become a major concern for both the hospitals and the patients. The increase in competition coupled with the increased patients' perception of service quality makes it difficult for hospitals to provide services that meet patient satisfaction. Recognition of the importance of service quality is the need of the hour in order to provide better services to the patients. The objectives of the present study are to identify the critical factors of inpatient service quality in a hospital and to develop the HospitalQual theoretical model to measure inpatient service quality. The present study was explorative and descriptive in its nature. An empirical study was conducted in a public hospital located in Hyderabad, India. The data was collected through a self administered questionnaire from 246 in-patients with a purposive sampling technique. The statistical techniques such as factor analysis and the multiple regression were used in the data analysis. The study has identified the factors to measure the inpatient service quality and developed a comprehensive instrument i.e. "HospitalQual" with seven dimensions, namely; medical, nursing, support, administrative services, patient safety, communication and hospital infrastructure. In addition, the supportive services are found to be the most important factor to predict the overall inpatient service quality, followed by nursing services, administrative services, medical services, patient communication patient safety and hospital infrastructure. The application of HospitalQual would help to identify the gaps in each of the dimensions over a period of time and enable hospital administrators to monitor, control and improve the inpatient service quality in a hospital.
Background: The tobacco use epidemic is one of the major global public health challenges and causes > 7 million deaths each year, including ~70 000 Saudis who die from smoking-related diseases. Aims: To present recent government initiatives in Saudi Arabia that have been designed to combat tobacco use in the country. Methods: This was a review based on secondary data sources such as published reports, articles in newspapers, and research studies published in various journals. Results: We present initiatives taken from June 2017 to April 2019 by the Saudi government to combat tobacco use, including value-added tax on tobacco, antismoking campaigns, antismoking clinics, mobile apps and other initiatives. Conclusion: The study suggests that the government should evaluate the impact of these initiatives on tobacco control in Saudi Arabia.
Background Chewing tobacco and other types of smokeless tobacco use have had less attention from the global health community than smoked tobacco use. However, the practice is popular in many parts of the world and has been linked to several adverse health outcomes. Understanding trends in prevalence with age, over time, and by location and sex is important for policy setting and in relation to monitoring and assessing commitment to the WHO Framework Convention on Tobacco Control. Methods We estimated prevalence of chewing tobacco use as part of the Global Burden of Diseases, Injuries, and RiskFactors Study 2019 using a modelling strategy that used information on multiple types of smokeless tobacco products. We generated a time series of prevalence of chewing tobacco use among individuals aged 15 years and older from 1990 to 2019 in 204 countries and territories, including age-sex specific estimates. We also compared these trends to those of smoked tobacco over the same time period. FindingsIn 2019, 273•9 million (95% uncertainty interval 258•5 to 290•9) people aged 15 years and older used chewing tobacco, and the global age-standardised prevalence of chewing tobacco use was 4•72% (4•46 to 5•01). 228•2 million (213•6 to 244•7; 83•29% [82•15 to 84•42]) chewing tobacco users lived in the south Asia region. Prevalence among young people aged 15-19 years was over 10% in seven locations in 2019. Although global agestandardised prevalence of smoking tobacco use decreased significantly between 1990 and 2019 (annualised rate of change: -1•21% [-1•26 to -1•16]), similar progress was not observed for chewing tobacco (0•46% [0•13 to 0•79]). Among the 12 highest prevalence countries
Background The sustainable development goals (SDGs) aim to end HIV/AIDS as a public health threat by 2030. Understanding the current state of the HIV epidemic and its change over time is essential to this effort. This study assesses the current sex-specific HIV burden in 204 countries and territories and measures progress in the control of the epidemic.Methods To estimate age-specific and sex-specific trends in 48 of 204 countries, we extended the Estimation and Projection Package Age-Sex Model to also implement the spectrum paediatric model. We used this model in cases where age and sex specific HIV-seroprevalence surveys and antenatal care-clinic sentinel surveillance data were available. For the remaining 156 of 204 locations, we developed a cohort-incidence bias adjustment to derive incidence as a function of cause-of-death data from vital registration systems. The incidence was input to a custom Spectrum model. To assess progress, we measured the percentage change in incident cases and deaths between 2010 and 2019 (threshold >75% decline), the ratio of incident cases to number of people living with HIV (incidence-to-prevalence ratio threshold <0•03), and the ratio of incident cases to deaths (incidence-to-mortality ratio threshold <1•0). FindingsIn 2019, there were 36•8 million (95% uncertainty interval [UI] 35•1-38•9) people living with HIV worldwide. There were 0•84 males (95% UI 0•78-0•91) per female living with HIV in 2019, 0•99 male infections (0•91-1•10) for every female infection, and 1•02 male deaths (0•95-1•10) per female death. Global progress in incident cases and deaths between 2010 and 2019 was driven by sub-Saharan Africa (with a 28•52% decrease in incident cases, 95% UI 19•58-35•43, and a 39•66% decrease in deaths, 36•49-42•36). Elsewhere, the incidence remained stable or increased, whereas deaths generally decreased. In 2019, the global incidence-to-prevalence ratio was 0•05 (95% UI 0•05-0•06) and the global incidence-to-mortality ratio was 1•94 (1•76-2•12). No regions met suggested thresholds for progress.Interpretation Sub-Saharan Africa had both the highest HIV burden and the greatest progress between 1990 and 2019. The number of incident cases and deaths in males and females approached parity in 2019, although there remained more females with HIV than males with HIV. Globally, the HIV epidemic is far from the UNAIDS benchmarks on progress metrics.
Background Tuberculosis is a major contributor to the global burden of disease, causing more than a million deaths annually. Given an emphasis on equity in access to diagnosis and treatment of tuberculosis in global health targets, evaluations of differences in tuberculosis burden by sex are crucial. We aimed to assess the levels and trends of the global burden of tuberculosis, with an emphasis on investigating differences in sex by HIV status for 204 countries and territories from 1990 to 2019. MethodsWe used a Bayesian hierarchical Cause of Death Ensemble model (CODEm) platform to analyse 21 505 siteyears of vital registration data, 705 site-years of verbal autopsy data, 825 site-years of sample-based vital registration data, and 680 site-years of mortality surveillance data to estimate mortality due to tuberculosis among HIV-negative individuals. We used a population attributable fraction approach to estimate mortality related to HIV and tuberculosis coinfection. A compartmental meta-regression tool (DisMod-MR 2.1) was then used to synthesise all available data sources, including prevalence surveys, annual case notifications, population-based tuberculin surveys, and tuberculosis cause-specific mortality, to produce estimates of incidence, prevalence, and mortality that were internally consistent. We further estimated the fraction of tuberculosis mortality that is attributable to independent effects of risk factors, including smoking, alcohol use, and diabetes, for HIV-negative individuals. For individuals with HIV and tuberculosis coinfection, we assessed mortality attributable to HIV risk factors including unsafe sex, intimate partner violence (only estimated among females), and injection drug use. We present 95% uncertainty intervals for all estimates.Findings Globally, in 2019, among HIV-negative individuals, there were 1•18 million (95% uncertainty interval 1•08-1•29) deaths due to tuberculosis and 8•50 million (7•45-9•73) incident cases of tuberculosis. Among HIV-positive individuals, there were 217 000 (153 000-279 000) deaths due to tuberculosis and 1•15 million (1•01-1•32) incident cases in 2019. More deaths and incident cases occurred in males than in females among HIV-negative individuals globally in 2019, with 342 000 (234 000-425 000) more deaths and 1•01 million (0•82-1•23) more incident cases in males than in females. Among HIV-positive individuals, 6250 (1820-11 400) more deaths and 81 100 (63 300-100 000) more incident cases occurred among females than among males in 2019. Age-standardised mortality rates among HIV-negative males were more than two times greater in 105 countries and age-standardised incidence rates were more than 1•5 times greater in 74 countries than among HIV-negative females in 2019. The fraction of global tuberculosis deaths among HIV-negative individuals attributable to alcohol use, smoking, and diabetes was 4•27 (3•69-5•02), 6•17 (5•48-7•02), and 1•17 (1•07-1•28) times higher, respectively, among males than among females in 2019. Among individuals with HIV and tuberculosi...
