OBJECTIVES
This study investigated the risk of developing and dying from all types of cancer, as well as cancer-specific mortality, in women diagnosed with prediabetes and diabetes.
METHODS
We included women aged ≥40 years who underwent cancer screening from 2009 to 2014 with follow-up until 2020. Diabetes status was determined based on fasting plasma glucose levels, self-reported history of diabetes, and the use of antidiabetic medication. We quantified the risk of cancer and mortality in the prediabetes and diabetes groups, relative to the normoglycemia group, by calculating adjusted hazard ratios (aHRs).
RESULTS
The study included 8,309,393 participants with a mean age of 52.7±9.7 years. Among these participants, 522,894 cases of cancer and 193,283 deaths were detected. An increased risk of cancer was observed in both the prediabetes group (aHR, 1.03; 95% confidence interval [CI], 1.02 to 1.04) and the diabetes group (aHR, 1.13; 95% CI, 1.12 to 1.14). The highest risk was identified in those with diabetes who developed liver (aHR, 1.72; 95% CI, 1.66 to 1.79), pancreatic (aHR, 1.68; 95% CI, 1.60 to 1.76), and gallbladder cancer (aHR, 1.43; 95% CI, 1.36 to 1.51). Women with prediabetes and diabetes exhibited a 1.07-fold (95% CI, 1.05 to 1.08) and 1.38-fold (95% CI, 1.36 to 1.41) increased risk of death from cancer, respectively.
CONCLUSIONS
Both prediabetes and diabetes were associated with an elevated risk of cancer, as well as an increased risk of death from cancer, in middle-aged Korean women. However, the degree of risk varied depending on the specific site of the cancer.; Summary

Korean summary
40세 이상의 중년 여성에서 당뇨 또는 당뇨 전 단계는 암 발생 위험과 암으로 인한 사망위험을 증가시킴. 암 종별로는 위암, 대장암, 직장암, 간암, 담낭암, 췌장암, 유방암, 자궁경부암, 자궁암, 신장암, 방광암의 발생 위험이 증가한 반면, 갑상선암의 발생 위험은 감소하였음. 거의 대부분의 암종에서 당뇨는 암으로 인한 사망위험을 증가시킴

Key Message
Both prediabetes and diabetes were independently associated with an overall increased risk of cancer, with a stronger association with malignancies in the liver and pancreas in women. Additionally, both prediabetes and diabetes status are associated with an elevated risk of death from cancer. These findings support the need for prevention and management to reduce cancer-related burden and premature deaths due to cancer, not only in individuals with diabetes but also in those with prediabetes.

Abstract

OBJECTIVES
This study investigated how changes in metabolic syndrome (MetS) are associated with the subsequent risk of breast and endometrial cancer according to menopausal status.

METHODS

This cohort study, using data from the National Health Insurance Service database, included women aged ≥40 years who underwent 2 biennial cancer screenings (2009-2010 and 2011-2012) and were followed up until 2020. Participants were grouped into MetS-free, MetS-recovery, MetS-development, and MetS-persistent groups. Menopausal status (premenopausal, perimenopausal, and postmenopausal) was assessed at 2 screenings. Cox proportional hazard regression was used to assess the association between MetS changes and cancer risk.

RESULTS

In 3,031,980 women, breast and endometrial cancers were detected in 39,184 and 4,298, respectively. Compared with the MetS-free group, those who recovered, developed, or had persistent MetS showed an increased risk of breast cancer, with adjusted hazard ratios (aHRs) of 1.05, 1.05, and 1.11, respectively (p<0.005). MetS persistence was associated with an increased risk of breast cancer in postmenopausal women (aHR, 1.12, 95% confidence interval [CI], 1.08 to 1.16) but not in premenopausal or perimenopausal women. MetS persistence was associated with an increased risk of endometrial cancer in premenopausal, perimenopausal, and postmenopausal women, with aHRs of 1.41 (95% CI, 1.17 to 1.70), 1.59 (95% CI, 1.19 to 2.12), and 1.47 (95% CI, 1.32 to 1.63), respectively.

CONCLUSIONS

Increased breast cancer risk was associated with recovered, developed, and persistent MetS in postmenopausal women. Meanwhile, increased endometrial cancer risk was found in obese women who recovered from MetS or persistently had MetS, regardless of menopausal status, when compared to MetS-free women.

Summary

Korean summary
- 폐경후 여성에서 대사증후군이 회복되었거나, 지속적으로 대사증후군을 앓고 있거나, 대사증후군이 발병한 여성은 유방암 위험과 관련이 있었습니다. - 한편, 폐경 상태와 관계없이 대사증후군에서 회복되었거나 지속적으로 대사증후군를 앓고 있는 비만 여성은 대사증후군이 없는 여성에 비해 자궁내막암 위험이 증가하는 것으로 나타났습니다.

Key Message
- Increased breast cancer risk was associated with recovered, developed, and persistent MetS in postmenopausal women. - Increased endometrial cancer risk was found in obese women who recovered from MetS or persistently had MetS, regardless of menopausal status, when compared to MetS-free women.

Abstract

OBJECTIVES
This study examined how trends in the weekly frequencies of gastrointestinal infectious diseases changed before and during the coronavirus disease 2019 (COVID-19) pandemic in Korea, and compared them with the trends in the United States.

METHODS

We compared the weekly frequencies of gastrointestinal infectious diseases (16 bacterial and 6 viral diseases) in Korea during weeks 5-52 before and after COVID-19. In addition, the weekly frequencies of 5 gastrointestinal infectious diseases in the United States (data from the Centers for Disease Control and Prevention) that overlapped with those in Korea were compared.

RESULTS

The mean weekly number of total cases of gastrointestinal infectious diseases in Korea showed a significant decrease (from 522 before COVID-19 to 245 after COVID-19, p<0.01). Only bacterial gastrointestinal infectious diseases caused by Campylobacter increased significantly; other bacterial gastrointestinal infectious diseases showed either a decrease or no change. The incidence of all other viral diseases decreased. In the United States, the weekly numbers of Salmonella, Campylobacter, typhoid, shigellosis, and hepatitis A virus cases sharply decreased after the COVID-19 outbreak. The weekly case numbers of all viral diseases markedly decreased in both countries; however, bacterial gastrointestinal infectious diseases showed a different pattern.

CONCLUSIONS

The incidence of gastrointestinal infectious diseases decreased after the COVID-19 outbreak. In contrast, Campylobacter infections showed an increasing trend in Korea, but a decreasing trend in the United States. Further studies are needed to elucidate the different trends in bacterial and viral infectious diseases before and after non-pharmaceutical interventions and between different countries.

Summary

Korean summary
한국과 미국 모두 코로나-19 발생 이후 위장관 감염 질환의 발생은 감소하고 있습니다. 하지만, 미국과 달리 한국에서는 캄필로박터 감염은 증가 하고 있습니다. 이는 COVID-19이 발생한 이후 캄필로박터 감염의 열악한 통제의 가능성을 설명할 수 있습니다.

Key Message
The incidence of gastrointestinal infectious diseases decreased after the COVID-19 outbreak, however, campylobacter infections showed an increasing trend in Korea, unlike the United States, which could explain the poor control of Campylobacter.
