Purpose: Proton pump inhibitors (PPIs) are widely prescribed for gastrointestinal disorders. Lansoprazole, a PPI, has been recognized for its potential effects of improving insulin resistance, reduction of oxidative stress, and improvement in atherosclerosis through peroxisome proliferator-activated receptor gamma (PPARγ) induction. This study aims to investigate whether lansoprazole poses a distinct risk of coronary heart disease (CHD) compared to other PPIs.

Article Synopsis
  • Thyroid cancer rates have risen significantly among Taiwanese females, with age-adjusted rates increasing from 7.37 to 20.53 per 100,000 people between 1995-1999 and 2015-2019, respectively.
  • The study found younger females showed the highest increase in incidence rates, particularly in the 50-54 age group, with a notable trend linked to later birth cohorts.
  • Researchers suggested that overdiagnosis might largely explain this trend, alongside a significant negative correlation between thyroid cancer incidence and fertility rates, highlighting a need for further investigation into these relationships.

The safety of human papillomavirus (HPV) vaccines has been evaluated continuously in pre-licensure clinical trials, post-marketing surveillance systems, and observational studies. Most studies have found no significant association between serious adverse events and HPV vaccination. However, these studies have focused on Western populations; similar studies focusing on Asian populations are insufficient.

Article Synopsis
  • In Taiwan, high rates of cigarette smoking, betel chewing, and alcohol consumption have led to significant cancer deaths, particularly in the oral cavity and throat.
  • Analysis from 1980 to 2019 showed strong links between these cancers and lifestyle factors, with a notable period effect from 1990 to 2009 related to betel nut consumption and an ongoing effect from HPV on oropharyngeal cancers.
  • Government initiatives to reduce smoking and betel quid usage since the 1990s have successfully stabilized cancer rates, suggesting continued policy impact may lead to further declines in head and neck cancer incidence.

Previous studies have indicated that HBV infection and T2DM are the factors that increase the risk of developing HCC. The experimental evidence has shown that antiglycemic agents may reduce the risk of HCC. However, the effect of dipeptidyl peptidase-4 inhibitors (DPP-4 inhibitors) on the risk of HCC in T2DM patients with chronic HBV infection remains unclear.
