Abstract
OBJECTIVE To compare quality of life (Qol) of patients with stage IB2-IIA cervical cancer treated by neoadjuvant treatments followed by radical surgery (NTS) or standard chemoradiation (CRT). METHODS Patients with stage IB2-IIA cervical cancer during 2006-2012 were treated with NTS or CRT and were invited to participate. The Functional Assessment of Cancer Therapy-Cervix (FACT-Cx) Questionnaire was used to assess patient Qol. A multivariable linear regression analysis was performed to identify factors associated with Qol. RESULTS In total, 90 (78.3%) out of 115 eligible patients completed the questionnaires. No significant differences were found in Qol between treatment groups, except that patients after NTS reported higher scores in the social/family well-being (e.g. satisfaction with sexual life, close relationships with partner or friends, and support from friends) than those after CRT, in particular, during 2-3 years after treatment. Results of multivariate analysis indicated that NTS was associated with better social/family functioning, while advanced stage of cervical cancer, lower family income and lower education were associated with impaired Qol in different domains. CONCLUSIONS Although self-reported Qol after treatment were not significantly different, NTS treated patients reported better social/family functioning than CRT treated patients, such as satisfaction with their sexual life and close relationships with partner or friends, during 2-3 years post treatment. These results were helpful for physicians to make treatment decisions while considering treatment-related Qol, and moreover, for rehabilitation and supportive care of patients after treatment. Further validation of our findings in randomized, controlled clinical trials is warranted.

Abstract
To study the effect of formulas on the estimation of dietary sodium intake (sodium intake) and its association with mortality, we analyzed the TOHP (Trials of Hypertension Prevention) follow-up data. Sodium intake was assessed by measured 24-hour urinary sodium excretion and estimations from sodium concentration using the Kawasaki, Tanaka, and INTERSALT (International Cooperative Study on Salt, Other Factors, and Blood Pressure) formulas. We used both the average of 3 to 7 urinary measurements during the trial period and the first measurement at the beginning of each trial. Additionally, we kept sodium concentration constant to test whether the formulas were independently associated with mortality. We included 2974 individuals aged 30 to 54 years with prehypertension, not assigned to sodium intervention. During a median 24-year follow-up, 272 deaths occurred. The average measured sodium intake was 3766±1290 mg/d. All estimated values, including those with constant sodium concentration, were systematically biased with overestimation at lower levels and underestimation at higher levels. There was a significant linear association between the average measured sodium intake (ie, gold standard method) and mortality. This relationship was altered by using the estimated sodium intakes. There appeared to be a J- or U-shaped relationship for the average estimated sodium by all formulas. Despite variations in the sodium-mortality relationship among various formulas, a common pattern was that all estimated values including those with constant sodium appeared to be inversely related to mortality at lower levels of sodium intake. These results demonstrate that inaccurate estimates of sodium cannot be used in association studies, particularly as the formulas per se seem to be related to mortality independent of sodium.
