A longitudinal study of sexual activity and influencing factors in breast cancer patients during treatment in the Southwest of China: a trajectory analysis model.

PURPOSE: The aim of this study was to describe the longitudinal developmental trajectories and its influencing factors of sexual activity in patients with breast cancer during treatment. METHODS: A prospective longitudinal study was conducted, including 225 newly diagnosed breast cancer patients in A tumor specialty three-class hospital in Southwest China. We measured sexual activity at the time of admission and diagnosis (T0) and one month (T1), three months (T2), six months (T3), and nine months (T4) after diagnosis. A trajectory analysis model (GBTM) was used to explore the changes in sexual activity in breast cancer patients. Multivariate binary logistic regression analysis was used to analyse the factors that affected the classification of sexual activity trajectories. RESULTS: The ratio of sexual activity abruptly declined from 100% at baseline to 39.1% at T1. The percentage of sexual activity was improved, from 51.4% at T2 to 63.1% at T4. The optimal model was a 2-group trajectory of sexual activity in breast cancer patients,36.6% in the "low activity group" and 63.4% in the "high activity group." The multivariate binary logistic regression analysis revealed statistically significant and positive correlations between sexual activity and age (ß = 0.085, OR = 1.089, 95%CI 1.035 ∼ 1.145, P = 0.001),libido(ß = 0.774, OR = 2.168, 95%CI 1.337 ∼ 3.515, P = 0.002), vaginal lubrication(ß = 1.254, OR = 33.503, 95%CI 2.000 ∼ 6.137, P<0.001). CONCLUSIONS: Breast cancer patients exhibited varying levels of sexual activity during treatment; higher age was associated with increased sexual activity, which can contribute to the recovery of sexual function. Therefore, it is crucial to provide appropriate guidance on sexual health for younger patients.

Guide wire electrode versus liquid electrode for intravascular electrocardiography-guided central venous catheterization in adults: A systematic review and meta-analysis.

AIM: To assess the effectiveness and safety of guide wire electrode versus liquid electrode for intravascular electrocardiography-guided central venous catheter placement in adults. DESIGN: Systematic review and meta-analysis. DATA SOURCES: We searched the main electronic databases (Cochrane Library, the Joanna Briggs Institute Library, Embase, PubMed, CINAHL, China National Knowledge Infrastructure, and Wanfang) with articles published from inception up to March 2018. References of important articles were also screened for relevant studies. We used a structured search strategy and did not apply any search limitations. REVIEW METHODS: Randomized, controlled trials, quasi-experimental studies or studies using a within-subject design, evaluating guide wire electrode versus liquid electrode for intravascular electrocardiography-guided central venous catheter placement in adults, were eligible for inclusion. Risk of bias assessment was performed using the Cochrane Collaboration's tool and meta-analysis was performed using RevMan 5.3. RESULTS: In total, six studies with a total of 2176 participants were included. Meta-analysis showed that there was no statistically significant difference in accuracy of tip location placement between guide wire and liquid electrodes. Use of guide wire electrode had a higher risk of complications which were transient and there were an insufficient number of studies using the same parameters to evaluate intravascular electrocardiography signal quality. CONCLUSION: Due to the small number and low quality of identified studies, it is difficult to draw definitive conclusions on the relative effectiveness and safety of guide wire versus liquid electrodes for the placement of central venous catheters in adults. More well-designed studies are needed in the future.
