RESUMO
OBJECTIVE: In this study, we investigated whether regular use of aspirin or acetaminophen was associated with risk of cervical cancer in women treated at an American cancer hospital. METHODS: This case-control study included 328 patients with cervical cancer and 1,312 controls matched on age and decade enrolled. Controls were women suspected of having but not ultimately diagnosed with a neoplasm. Analgesic use was defined as regular (at least once per week for ≥6 months), frequent (≥7 tablets/week), very long term (≥11 years), or frequent, long term (≥7 tablets per week for ≥5 years). RESULTS: Compared to nonusers, frequent aspirin use was associated with decreased odds of cervical cancer (odds ratio, 0.53; 95% confidence interval, 0.29-0.97). A slightly larger association was observed with frequent, long-term use of aspirin (odds ratio, 0.46; 95% confidence interval, 0.22-0.95). Acetaminophen use was not associated with the risk of cervical cancer. CONCLUSIONS: Our findings suggest that frequent and frequent, long-term use of aspirin is associated with decreased odds of cervical cancer. To our knowledge, this is the first US-based study examining these associations. Given the widespread use of nonsteroidal anti-inflammatory drugs and acetaminophen worldwide, further investigations of the possible role of analgesics in cervical cancer, using a larger sample size with better-defined dosing regimens, are warranted.

In nonpregnant populations, sleep-disordered breathing (SDB) has been associated with cardiovascular and metabolic disease. Few studies have examined the relationship between SDB and adverse pregnancy outcomes (APO). The objective of this study was to examine the association between SDB and APO. Women who had a delivery as well as an in-laboratory polysomnogram (PSG) were identified. Demographics, PSG results, and pregnancy outcomes were abstracted from the medical record. Absence of SDB was defined as an apnea hypopnea index (AHI) of <5, mild SDB as an AHI of 5 to 14.9, and moderate to severe SDB as an AHI of ≥15. The primary outcome was a composite measure of APO: pregnancy-related hypertension, gestational diabetes, or preterm birth ≤34 weeks. We identified 143 women who had undergone a PSG and a delivery. Increasing severity of SDB was associated with an increasing risk of the composite APO: AHI <5, 18.1%; AHI 5 to 14.9, 23.5%; AHI ≥15, 38.5% (p = 0.038). Obese women (body mass index ≥30) with moderate to severe SDB had the highest rate of APO, 41.7%. SDB, especially moderate to severe disease, may be associated with APO. However, it is unclear if SDB is a risk factor for APO independent of obesity.
