How are multifactorial beliefs about the role of genetics and behavior in cancer causation associated with cancer risk cognitions and emotions in the US population?

Multifactorial causal beliefs and colorectal cancer screening: A structural equation modeling investigation

We tested a conceptual model that describes the relationship between individuals' understanding of the multifactorial nature of cancer and their self-reported colorectal cancer screening. We collected cross-sectional survey data from 205 men and women age 50-75. Data were analyzed using structural equation modeling. The proposed model had reasonable fit (RMSEA = 0.09, CFI = 0.65). Multifactorial causal beliefs were associated with cancer risk perceptions (β = 0.16, p = 0.019) and more optimistic cancer cognitions (β = 0.17, p = 0.013). However, these constructs were not associated with colorectal cancer screening (p's > 0.05). Further testing could reveal whether this model can be applied to other cancer-related health behaviors including lifestyle changes and genetic testing.

The effect of prophylactic rewarming on postoperative nausea and vomiting among patients undergoing laparoscopic hysterectomy: a prospective randomized clinical study

BACKGROUND

Postoperative nausea and vomiting (PONV) is a common complication from general anesthesia that impacts on postoperative recovery.

OBJECTIVE

To evaluate prophylactic rewarming following general anesthesia, so as to decrease the incidence of PONV among patients undergoing laparoscopic hysterectomy.

DESIGN AND SETTING

Prospective randomized clinical study at a hospital in China.

METHODS

Sixty-two patients were randomly assigned into two groups. The forced air warming (FAW) group received pre-warmed Ringer's solution with FAW until the end of surgery. The control group received Ringer's solution without FAW. The pre-warmed Ringer's solution was stored in a cabinet set at 40 °C. The FAW tube was placed beside the patient's shoulder with a temperature of 43 °C.

RESULTS

Sixty patients completed the study. The FAW group showed significant differences versus the controls regarding temperature. At 6, 24 and 48 hours postoperatively, the incidences of PONV were 53.3%, 6.7% and 3.3% in the FAW group versus 63.3%, 30% and 3.3% in the controls. VAS scores were significantly lower in the FAW group than in the controls at 24 hours (P= 0.035). Forty-item questionnaire total scores in the FAW group were significantly higher than in the controls. The physical independence and pain scores at 24 hours and emotional support and pain scores at 48 hours in the FAW group were higher than in the controls (P < 0.05). There was no difference in hemodynamics or demographics between the two groups (P > 0.05).

CONCLUSIONS

Prophylactic rewarming relieved PONV and improved the quality of postoperative recovery.

Predictors of genetic beliefs toward cancer risk perceptions among adults in the United States: Implications for prevention or early detection

The objective of this study is to assess predictors of genetic beliefs toward cancer risk perceptions among adults, aged 18 years and over, in the United States (US). Data were obtained from the National Cancer Institute's (NCI) Health Information National Trends Survey 2014 (HINTS) 4 Cycle 4. Bivariate and multivariable logistic regression analyses were conducted to assess factors associated with an individual's beliefs about genetic and cancer risk perceptions. The results showed that African Americans, Non-White Hispanics, Non-Hispanic Asians, individuals with a high school education or less, and annual household incomes less than $20,000 and do not believe that health behaviors play some role in determining whether a person will develop cancer was significantly less likely to report that genetics plays at least some role in whether a person will develop cancer. Findings of this study provide an opportunity for genetic counselors to address beliefs about genetics and cancer risk perceptions among minority populations and promote health equity.
