Radioactive iodine (129I) is of great concern owing to its high mobility in the environment and long-term radiotoxicity. However, there is a lack of effective techniques for removing iodate (IO3-) from aqueous solution. This study aims to develop a new technique for removing radioactive iodate from contaminated solution by using barite (BaSO4). We examined the coprecipitation mechanism of iodate by barite at the molecular level to determine the optimum conditions for iodate removal. Results showed that iodate was effectively removed from the aqueous solution by coprecipitation even in the presence of competitive anions. Based on comparison of our method with previous techniques, the iodate removal efficiency by barite was determined to be about two orders of magnitude greater than that by hydrotalcite-like layered double hydroxide at 10 mmol L-1 Cl-. Extended X-ray absorption fine structure analysis indicated that the incorporated iodate was strongly bound to the crystal lattice of barite by substituting the sulfate site in the structure when the iodine concentration was low. The charge compensation problem from the IO3- substitution in the SO42- site was achieved by the substitution of Na+-IO3- pairs at the nearest Ba2+ site. Given the high removal efficiency and strong binding of iodate to barite, coprecipitation with barite is a promising tool for removing radioactive iodate from various aqueous solutions contaminated with iodate.Arsenic is a well-established human carcinogen and is considered a health risk worldwide, especially where groundwater is consumed as drinking water. In 2018, bladder and kidney cancers were the 14th and 17th leading causes of global cancer mortality, respectively. Our aim was to investigate the association between arsenic exposure, DNA damage, and the incidence of bladder and kidney cancers. A total of 788 participants aged ≥40 years were enrolled in a prospective cohort study in Taiwan between 1991 and 1994, with follow-up between 2011 and 2014. Well-water and first-morning spot urine samples were collected between 1991 and 1994 to estimate arsenic exposure, and the baseline urinary levels of 8-Oxo-2'-deoxyguanosine (8-OHdG) and N7-methylguanine (N7-MeG) were quantified to assess DNA lesions. The Cox proportional hazard model was used to estimate the effects of arsenic exposure and DNA adduct levels on the risk of bladder or kidney cancer. Urinary arsenic species were associated with significantly increased 8-OHdG and N7-MeG after adjusting for age, sex, and cigarette smoking. Only non-statistically significant mediation effects of 8-OHdG were observed. In a fully adjusted Cox model, participants with arsenic exposure and urinary 8-OHdG levels higher than the median had a higher risk of bladder cancer (HR = 4.60, confidence interval 1.43-14.85). Overall, the combined effects of high cumulative arsenic exposure from artesian well-water and advanced DNA damage predicted the risk of bladder cancer.
Clinical breast examination (CBE) is an integral component of triple assessment for women presenting with symptomatic breast disease. Four common search patterns of CBE are "dial of a clock" (DC), "vertical strips" (VS), "quadrant-wise" (QW), and "concentric circles" (CC). The most sensitive search pattern of CBE has not been established.

A cross-sectional study was conducted on women with symptomatic breast disease, to measure various diagnostic performance indices of four different search patterns of CBE by a professor, a surgical resident trainee, and a trained nurse. Women were examined one at a time randomly by three examiners. Each examiner examined with four different search patterns of CBE, one method at a time. Any nodularity or lump detected was noted and the findings were compared with breast sonography, which was considered as the gold standard. Statistical analysis was done using STATA 14, SPSS 20, and OpenEpi software for diagnostic test indices.

Sixty women (mean age=39.6) with palpable findings of both breasts were included (n=120). Most women presented with complaints of breast lump (70%) and mastalgia (27%). Sensitivity was highest for DC as elaborated [% (95% confidence interval)] DC[73.2 (60-83)] > CC[66 (53-77)] > VS[62.5 (49-73)] > QW[58.9 (45-70)] for professor; DC[64.2 (51-75)] > VS[62.5 (49-73)] > CC[57.1 (44-69)] > QW[57.1 (44-69)] for resident; and DC[82.1 (70- 90)] > VS[78.5 (66-87)] > CC(75 (62-84)] > QW[73.2 (60-83)] for nurse. Seclidemstat purchase The minimum sonographic tumor size picked up by DC by all the examiners was 7mm.

The DC search pattern of CBE demonstrated the highest sensitivity for all the examiners. The trained nurse achieved the highest sensitivity among all the examiners.

The impact of the stage of cancer on perioperative mortality remains obscure. The purpose of this study was to investigate whether cancer stage influences 30-d mortality for gastric, pancreatic, and colorectal cancers.

Data were collected from the National Cancer Database for patients undergoing resections for cancers of the stomach, pancreas, colon, or rectum between 2004 and 2015. The main analysis was conducted among patients with cancer stages 1-3. A sensitivity analysis also included cancer stage 4. Descriptive statistics were used to compare the patients' baseline characteristics. Generalized linear mixed models were used to evaluate the relationship between stage and 30-d mortality, controlling for other disease-, patient- and hospital-level factors. Pseudo R2 statistics (%Δ pseudo R
) were used to quantify the relative explanatory capacity of the variables to the model for 30-d mortality. All analyses were performed using SAS 9.4.

The cohort included 24,468, 28,078, 176,285, and 64,947 patients with stomach, pancreas, colon, and rectal cancers, respectively. After adjusting for other variables, 30-d mortality was different by stage for all cancer types examined. The factor most strongly associated with 30-d mortality was age (%Δ pseudo R
range 14%-39%). The prognostic impact of cancer stage (Stages 1, 2, or 3) on 30-d mortality was comparable to that of the Charlson comorbidity index.

Cancer stage contributes to explaining differences observed in short-term mortality for gastrointestinal cancers. Short-term mortality models would benefit by including more granular cancer stage, beyond disseminated status alone.
