Evaluation of homeobox protein B13 (HOXB13) gene G84E mutation in patients with prostate cancer.

OBJECTIVES: To comprehensively investigate the potential association between prostate cancer (PCa) and the G84E mutation within the Homeobox Protein B13 (HOXB13) gene among individuals of Turkish descent, our study aims to undertake a prospective examination. METHODS: We evaluated 300 patients (150 diagnosed with prostate cancer, 150 controls) who presented in our clinic. Data collected were prospectively examined. DNA isolation was performed using an isolation kit. The HOXB13-G84E mutation (rs138213197) was analyzed in the obtained samples. Data encoding and statistical analysis were performed. RESULTS: The pathological allele for the G84E mutation was T. According to the findings, no mutations were detected in the control group, while the G84E mutation was detected in 17 patients in the patient group, all of whom had the TC genotype. The analysis showed that having the CC genotype reduced the risk of prostate cancer by 0.47 times (OR=0.47, CI=0.415-0.532). Our results did not support a trend toward family history or earlier-onset disease in comparisons between carriers and non-carriers of HOXB13 G84E mutation. Individuals with a positive family history exhibited a higher frequency of the G84E mutation. CONCLUSIONS: We concluded that HOXB13 gene mutation is indeed linked to PCa in Turkish men. However, we did not find a relationship between the HOXB13 gene G84E mutation carrier status and either early-onset PCa or familial PCa in Turkish men.

The effect of duloxetine on female sexual functions in the treatment of stress incontinence.

OBJECTIVES: Stress urinary incontinence (SUI) is defined as urinary incontinence that occurs with coughing, sneezing, and physical exercise. It is frequently observed in women after middle age and has a negative impact on their sexual function. Duloxetine as one of the Serotonin-noradrenaline reuptake inhibitors (SNRIs) is commonly used in the non-surgical treatment of SUI. The aim of our study is to investigate the effect of duloxetine, which is used in the treatment of SUI, on sexual functions in female patients. METHODS: The study included 40 sexually active patients who received duloxetine 40 mg twice a day for the treatment of SUI. All patients had female sexual function index (FSFI), Beck's depression inventory (BDI), and incontinence quality of life score (I-QOL) applied before and 2 months after starting duloxetine treatment. RESULTS: FSFI total score significantly increased from 19.9 to 25.7 (p < 0.001). In addition, significant improvement was observed in all sub-parameters of FSFI, including arousal, lubrication, orgasm, satisfaction, and pain/discomfort (p < 0.001, for each FSFI subtotal score). BDI significantly decreased from 4.5 to 1.5 (p < 0.001). I-QOL score significantly increased from 57.6 to 92.7 after the duloxetine treatment. CONCLUSIONS: Although SNRIs carry a high risk of sexual dysfunction, duloxetine may have an indirect positive effect on female sexual activity, both through its stress incontinence treatment and its antidepressant effect. In our study, Duloxetine, one of the treatment options for stress urinary incontinence and an SNRI, has a positive effect on stress urinary incontinence, mental health, and sexual activity in patients with SUI.
