Introduction: Prevention of colorectal cancer (CRC) via reduction of lifestyle risk factors, and participation in bowel screening are two ways in which public engagement could lower mortality from colorectal cancer. This study examined public awareness of lifestyle risk factors and bowel screening, with determination of the factors affecting this.
Methods: A representative population sample (n = 1969) was surveyed using a study specific postal questionnaire to determine demographics, experience of bowel problems, awareness of lifestyle risk factors, knowledge about the incidence of CRC and potential benefits of screening, as well as personal experience of screening.
Results: The majority of respondents were aged over 50 (74%). 77% had either personal experience or a relative/friend with experience of a bowel problem. Knowledge of dietary advice was better than risks relating to weight and physical activity. Awareness of lifestyle risk factors was significantly worse in those less than 50 years old (p = 0.0004) and with a lower level of education (p = 0.0021). Awareness of bowel cancer diagnosis was significantly lower in those less than 50 years old (p=<0.0001). The most frequent reason for non-completion of a screening kit was that the process was dirty and unpleasant.
Conclusion: Initiatives are required to improve awareness of younger people with regard to lifestyle risk factors for CRC, especially since this group stand to benefit most from risk reduction. Those with a lower educational level also had poor awareness but felt that the NHS should not prescribe exercise and lifestyle change; targeting this group would need to take this into account.

Objective: Addressing the rising cancer rates through timely diagnosis and treatment is crucial. Additionally, cancer survivors need to understand the potential risk of developing secondary cancer (SC), which can be influenced by several factors including treatment modalities, lifestyle choices, and habits such as smoking and alcohol consumption. This study aims to establish a novel relationship using linear regression models between dose and the risk of SC, comparing different prediction methods for lung, colon, and breast cancer.

This delicate balance of microbiota plays an important role in health and disease and is highly influenced by lifestyle factors and the surrounding environment. As further research emerges, understanding the full potential of the gut microbiome and the impact of using nutraceuticals to positively influence its function may open the door to greater therapeutic outcomes in the treatment and prevention of disease.

Objective: This study aimed to assess the trend and factors associated with central obesity in four cross-sectional panels in schoolchildren aged 7-14 years between 2002 and 2019.
Methods: Waist circumference data were used to assess central obesity, and independent variables were gender, age, school shift (morning and afternoon), commuting to school method, mother's schooling, and family income. The chi-square test was used to assess the association between outcome and independent variables, and binary logistic regression was used to assess the predictors of central obesity and the effect size by odds ratio.
Background: Globally, gastrointestinal (GI) infections are common, particularly in populations with low socioeconomic levels, including high illiteracy rates, ignorance, poor housing and lifestyles, and unfavorable environmental conditions. These risk factors are the underlying cause of GI parasitic infections in many developing nations, including Nepal.
Aim: This study aimed to assess the prevalence and diversity of GI parasites and their association with a few risk factors within the marginalized indigenous Tharu people of the southern region of Nepal.

Background: The BCG vaccine induces trained immunity, an epigenetic-mediated increase in innate immune responsiveness. Therefore, this clinical trial evaluated if BCG-induced trained immunity could decrease coronavirus disease 2019 (COVID-19)-related frequency or severity.
Methods: A double-blind, placebo-controlled clinical trial of healthcare workers randomized participants to vaccination with BCG TICE or placebo (saline).
