Successful blood pressure (BP) control requires good adherence to medication and specific health‐related behaviors. However, the BP control rate is not optimal, and limited research has focused on the patient's perspective. This study aimed at investigating the illness perceptions of hypertensive patients and how they relate to drug adherence. One hundred and seventeen hypertensive patients enrolled in this study, and data were collected in a family physician clinic of a medical center located in northern Taiwan. The Illness Perception Questionnaire was administered, and medication adherence and demographic data were also collected. Results showed the patients' perceptions of their hypertension, that it was a chronically severe but stable disease, and the patients were confident in the effectiveness of medical treatments and their ability to control their disease. The participants were divided into three clusters by cluster analysis. There were 46.15% participants in the first cluster; they had less negative belief in their illness consequence and less negative emotional responses, but a low personal sense of control. The second cluster (11.97%) had more negative emotional responses and more negative beliefs in their illness consequence, but these individuals scored highly on their personal sense of control and treatment control beliefs. The third cluster (41.88%) had scores between clusters 1 and 2. Cluster 1 had the best drug adherence, and cluster 2 had the worst drug adherence (χ ² = 7.67, p < 0.05). It may be beneficial for clinical physicians to pay attention to patients' illness perceptions, including their negative emotional response and symptoms, in order to improve their drug adherence.

(1) Background: Colorectal cancer is one of the leading causes of cancer-related death, while early detection decreases incidence and mortality. Current screening programs involving fecal immunological testing and colonoscopy commonly bring about unnecessary colonoscopies, which adds burden to healthcare systems. The objective of this study was to provide an assessment of the diagnostic performance of an electronic nose serving as a complementary screening tool to improve current screening programs in clinical settings. (2) Methods: We conducted a case–control study that included patients from a medical center with colorectal cancer and non-colorectal cancer controls. We analyzed the composition of volatile organic compounds in their exhaled breath using the electronic nose. We then used machine learning algorithms to develop predictive models and provided the estimated accuracy and reliability of the breath testing. (3) Results: We enrolled 77 patients, with 40 cases and 37 controls. The area under the curve, Kappa coefficient, sensitivity, and specificity of the selected model were 0.87 (95% CI 0.76–0.95), 0.66 (95% CI 0.49–0.83), 0.81, and 0.85. For subjects at an early stage of disease, the sensitivity and specificity were 0.90 and 0.85. Excluding smokers, the sensitivity and specificity were 0.88 and 0.92. (4) Conclusions: This study highlights the promising potential of breath testing using an electronic nose for enabling early detection and reducing unnecessary treatments. However, more independent data for external validation are required to ensure applicability and generalizability.

This community-based study aimed to elucidate whether there is a gender difference in the effect of metabolic syndrome (MetS) and its individual components on an elevated risk for incident colorectal adenoma. A prospective cohort study was conducted by enrolling 59,767 subjects aged 40 years or older between 2001 and 2009 in Keelung, Taiwan, to test this hypothesis, excluding those with a prior history of colorectal cancer and those with colorectal cancer diagnosed at the first screening. Cox proportional hazards regression models were used to assess the effect of MetS in terms of a dichotomous classification, each individual component and the number of components for males and females. Colorectal adenoma was present in 2.7% (n = 652) of male participants and 1.1% (n = 403) of female participants. The prevalence rate of MetS was 26.7% and 23.3% for males and females, respectively. The effect of MetS on colorectal adenoma was statistically significant and similar for the 2 genders, with an adjusted hazard ratio (aHR) of 1.33 (95% CI: 1.13–1.58) in males and 1.33 (95% CI: 1.06–1.66) in females after adjustment for confounders. However, MetS led to higher risk of advanced colorectal adenoma in men than in women. Regarding the effect of each component of MetS on colorectal adenoma, abnormal waist circumference and hypertriglyceridemia led to an elevated risk of colorectal adenoma in both genders. A rising risk of colorectal adenoma among females was noted in those with a moderately higher level of glycemia (100–125 mg/dL, aHR = 1.44, 95% CI: 1.12–1.85). Hypertriglyceridemia and high blood pressure were associated with an increased risk of advance colorectal adenoma in males. Both male and female subjects with MetS had a higher risk of colorectal adenoma. The contributions from individual components of MetS varied by gender. These findings suggest that the possible risk reduction of colorectal adenoma through metabolic syndrome-based lifestyle modifications may differ between genders.
