The global, regional, and national burden of adult lip, oral, and pharyngeal cancer in 204 countries and territories:A systematic analysis for the Global Burden of Disease Study 2019

Importance Lip, oral, and pharyngeal cancers are important contributors to cancer burden worldwide, and a comprehensive evaluation of their burden globally, regionally, and nationally is crucial for effective policy planning.Objective To analyze the total and risk-attributable burden of lip and oral cavity cancer (LOC) and other pharyngeal cancer (OPC) for 204 countries and territories and by Socio-demographic Index (SDI) using 2019 Global Burden of Diseases, Injuries, and Risk Factors (GBD) Study estimates.Evidence Review The incidence, mortality, and disability-adjusted life years (DALYs) due to LOC and OPC from 1990 to 2019 were estimated using GBD 2019 methods. The GBD 2019 comparative risk assessment framework was used to estimate the proportion of deaths and DALYs for LOC and OPC attributable to smoking, tobacco, and alcohol consumption in 2019.Findings In 2019, 370 000 (95% uncertainty interval [UI], 338 000-401 000) cases and 199 000 (95% UI, 181 000-217 000) deaths for LOC and 167 000 (95% UI, 153 000-180 000) cases and 114 000 (95% UI, 103 000-126 000) deaths for OPC were estimated to occur globally, contributing 5.5 million (95% UI, 5.0-6.0 million) and 3.2 million (95% UI, 2.9-3.6 million) DALYs, respectively. From 1990 to 2019, low-middle and low SDI regions consistently showed the highest age-standardized mortality rates due to LOC and OPC, while the high SDI strata exhibited age-standardized incidence rates decreasing for LOC and increasing for OPC. Globally in 2019, smoking had the greatest contribution to risk-attributable OPC deaths for both sexes (55.8% [95% UI, 49.2%-62.0%] of all OPC deaths in male individuals and 17.4% [95% UI, 13.8%-21.2%] of all OPC deaths in female individuals). Smoking and alcohol both contributed to substantial LOC deaths globally among male individuals (42.3% [95% UI, 35.2%-48.6%] and 40.2% [95% UI, 33.3%-46.8%] of all risk-attributable cancer deaths, respectively), while chewing tobacco contributed to the greatest attributable LOC deaths among female individuals (27.6% [95% UI, 21.5%-33.8%]), driven by high risk-attributable burden in South and Southeast Asia.Conclusions and Relevance In this systematic analysis, disparities in LOC and OPC burden existed across the SDI spectrum, and a considerable percentage of burden was attributable to tobacco and alcohol use. These estimates can contribute to an understanding of the distribution and disparities in LOC and OPC burden globally and support cancer control planning efforts

The global burden of cancer attributable to risk factors, 2010-19 : a systematic analysis for the Global Burden of Disease Study 2019

Background Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings Globally, in 2019, the risk factors included in this analysis accounted for 4.45 million (95% uncertainty interval 4.01-4.94) deaths and 105 million (95.0-116) DALYs for both sexes combined, representing 44.4% (41.3-48.4) of all cancer deaths and 42.0% (39.1-45.6) of all DALYs. There were 2.88 million (2.60-3.18) risk-attributable cancer deaths in males (50.6% [47.8-54.1] of all male cancer deaths) and 1.58 million (1.36-1.84) risk-attributable cancer deaths in females (36.3% [32.5-41.3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20.4% (12.6-28.4) and DALYs by 16.8% (8.8-25.0), with the greatest percentage increase in metabolic risks (34.7% [27.9-42.8] and 33.3% [25.8-42.0]). Interpretation The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

Вплив загартування на механічні властивості монокристала In2Se2.7Sb0.3

Напівпровідникові сполуки III-VI є цікавими матеріалами для виготовлення таких приладів як детектори іонізуючого випромінювання, твердотільні електроди, іонні акумулятори, а також фоточутливі гетероструктури та сонячні елементи. Структурна складність сімейства In-Se спонукала нас до дослідження невивченого складу In2Se3 та його властивостей із легуванням сурмою (Sb). Метою даної роботи є вивчення впливу сурми на нову конфігурацію In2Se3. Потрійні напівпровідникові сполуки у вигляді монокристалів або тонких плівок викликають значний інтерес через свої структурні, оптичні та електричні властивості, які дозволяють їх широко використовувати в багатьох електронних і оптоелектронних пристроях. Оскільки світовий енергетичний ринок шукає застосування, які пропонують більш ефективні електронні системи, монокристали In2Se2.7Sb0.3, синтезовані за модифікованою вертикальною технікою Бріджмена, відкривають шлях для захоплюючих інновацій у твердотільних фотоелектричних системах та секторах чистої енергії. Ми виростили монокристал In2Se2.7Sb0.3 за методикою Бріджмена-Стокбаргера. Температурний градієнт системи підтримували на рівні 60 °С/см зі швидкістю росту 0,35 см/год. Випробування твердості має важливе значення для інтерпретації механічної поведінки матеріалів і корелює з іншими фізичними властивостями. Твердість до деформації вирощених кристалів залежить від міцності зчеплення та досконалості структури. Вимірювання мікротвердості розщеплених і загартованих зразків проводили за допомогою проекційного мікроскопа Віккерса. У статті результати досліджень обговорені та докладно викладені.III-VI semiconductor compounds are interesting materials for the fabrication of such devices as ionizing radiation detectors, solid-state electrodes, ion batteries, as well as photosensitive heterostructures and solar cells. The structural complexity of In-Se family has motivated us to examine an unexplored composition (In2Se3) and its properties with antimony doping (Sb). The purpose of the present work is to study the influence of antimony on the novel configuration In2Se3. Ternary semiconductor compounds in the form of single crystals or thin films have attracted considerable interest because of their structural, optical and electrical properties, which allow them to be widely used in many electronic and optoelectronic devices. As the global energy market seeks applications that offer more efficient electronic systems, In2Se2.7Sb0.3 single crystals synthesized by the modified vertical Bridgeman technique pave the way for exciting innovations in solid-state photovoltaic systems and clean energy sectors. We have grown In2Se2.7Sb0.3 single crystal using the Bridgman-Stockbarger technique. The temperature gradient of the system was kept at 60 °C/cm with a growth rate of 0.35 cm/h. Hardness testing is of significant importance in interpreting the mechanical behavior of materials and correlates with other physical properties. Hardness to deformation of as-grown crystals depends on the bond strength and structural perfection. The microhardness measurements of ascleaved and quenched samples were made by using a Vickers projection microscope. In this paper, the results have been discussed and reported in detail

The global, regional, and national burden of adult lip, oral, and pharyngeal cancer in 204 countries and territories : a systematic analysis for the global burden of disease study 2019

Abstract Importance: Lip, oral, and pharyngeal cancers are important contributors to cancer burden worldwide, and a comprehensive evaluation of their burden globally, regionally, and nationally is crucial for effective policy planning. Objective: To analyze the total and risk-attributable burden of lip and oral cavity cancer (LOC) and other pharyngeal cancer (OPC) for 204 countries and territories and by Socio-demographic Index (SDI) using 2019 Global Burden of Diseases, Injuries, and Risk Factors (GBD) Study estimates. Evidence review: The incidence, mortality, and disability-adjusted life years (DALYs) due to LOC and OPC from 1990 to 2019 were estimated using GBD 2019 methods. The GBD 2019 comparative risk assessment framework was used to estimate the proportion of deaths and DALYs for LOC and OPC attributable to smoking, tobacco, and alcohol consumption in 2019. Findings: In 2019, 370 000 (95% uncertainty interval [UI], 338 000‐401 000) cases and 199 000 (95% UI, 181 000-217 000) deaths for LOC and 167 000 (95% UI, 153 000‐180 000) cases and 114 000 (95% UI, 103 000‐126 000) deaths for OPC were estimated to occur globally, contributing 5.5 million (95% UI, 5.0‐6.0 million) and 3.2 million (95% UI, 2.9‐3.6 million) DALYs, respectively. From 1990 to 2019, low-middle and low SDI regions consistently showed the highest age-standardized mortality rates due to LOC and OPC, while the high SDI strata exhibited age-standardized incidence rates decreasing for LOC and increasing for OPC. Globally in 2019, smoking had the greatest contribution to risk-attributable OPC deaths for both sexes (55.8% [95% UI, 49.2%‐62.0%] of all OPC deaths in male individuals and 17.4% [95% UI, 13.8%‐21.2%] of all OPC deaths in female individuals). Smoking and alcohol both contributed to substantial LOC deaths globally among male individuals (42.3% [95% UI, 35.2%‐48.6%] and 40.2% [95% UI, 33.3%‐46.8%] of all risk-attributable cancer deaths, respectively), while chewing tobacco contributed to the greatest attributable LOC deaths among female individuals (27.6% [95% UI, 21.5%‐33.8%]), driven by high risk-attributable burden in South and Southeast Asia. Conclusions and relevance: In this systematic analysis, disparities in LOC and OPC burden existed across the SDI spectrum, and a considerable percentage of burden was attributable to tobacco and alcohol use. These estimates can contribute to an understanding of the distribution and disparities in LOC and OPC burden globally and support cancer control planning efforts
