Introduction:
Alcohol contributes to global morbidity and mortality. This study aimed to describe the prevalence and patterns of alcohol use, its correlates with health related quality of life (HRQoL) and chronic medical conditions in the Western Province of Sri Lanka.
Methods:
A cross-sectional study (2018-2020) was conducted in Western Province recruited 1800 adults (>20 years) via multi-stage stratified cluster sampling. Data collection included interviewer-administered questionnaires, physiological, anthropometric, and biochemical measurements. Alcohol consumption patterns were assessed with Alcohol Use Disorders Identification Test and CAGE tools, and HRQoL with RAND-36.
Results:
A total of 1333 adults participated. Alcohol consumption at any point in their life was reported by 25.5 % of participants (95 %CI:18.9-32.1), and 21.3 % (95 %CI:16.8-25.7) had consumed alcohol in the past year. The prevalence was highest among males (56.8 %;95 %CI:46.2-67.4), those aged 40-49 (27.9 %;95 %CI:20.9-34.6), residents of Gampaha district (33.2 %;95 %CI:21.4-44.9), rural dwellers (27.9 %;95 %CI:18.3-37.6), and those earning $300-400 monthly (46.5 %;95 %CI:28.4-64.6). Daily consumption was 5.2 % (95 %CI:1.9-8.3), harmful alcohol use was 28.1 % (95 %CI:19.5-36.7), and clinical alcoholism was 26.6 % (95 %CI:19.5-33.8) among alcohol consumers. Those without clinical alcoholism had higher quality of life than those with the condition. Comorbidities among consumers included dyslipidemia (81.3 %, undiagnosed:58.5 %), hypertension (61.6 %, undiagnosed:33.9 %), diabetes (41.4 %, undiagnosed:11.3 %), and prediabetes (33.8 %).
Conclusions:
One-fourth of Western Province adults reported alcohol consumption, highest among middle-aged, middle-income, and residents in Gampaha district. Cardio-metabolic diseases were high among individuals who consume alcohol, many remaining undiagnosed. Non-communicable diseases programs should focus high-risk screening, alcohol control, and preventive community initiatives.

The technique begins with separating proteins from the sample using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), followed by protein transfer, immunoblotting, and finally, protein detection.

Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.

Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...
