Significant relationship between parameters measured by transrectal color Doppler ultrasound and sexual dysfunction in patients with BPH 12 months after TURP.

BACKGROUND: A link between sexual dysfunction and lower urinary tract symptoms due to benign prostatic hyperplasia (BPH) has been noticed. Transurethral resection of the prostate (TURP) remains the standard treatment for symptomatic BPH, whether TURP causes sexual dysfunction is still uncertain. In this retrospective study, we investigated the relationship between parameters measured by color Doppler ultrasound (CDU) and sexual dysfunction in patients with BPH 12 months after TURP. METHODS: The parameters include presumed circle area ratio (PCAR), maximal horizontal area of seminal vesicles (MHA), resistive index of the prostate (RIP), and peak systolic velocity in the flaccid penis (PSV). The international prostate symptom score was used to evaluate the lower urinary tract symptoms and the five-item version of the International Index of Erectile Function was used to evaluate sexual function before and after TURP. RESULTS: Of the 103 patients without sexual dysfunction before TURP, 11 (10.7%) had erectile dysfunction (ED) after TURP. These 11 patients had significantly lower PCAR, RIP, PSV and MHA than those without ED. The patients with retrograde ejaculation after TURP had significantly lower PCAR than those without retrograde ejaculation, and the patients with premature ejaculation after TURP had significantly lower MHA than those without premature ejaculation. Comparing the parameters between baseline and after TURP, PCAR, RIP, and MHA decreased significantly in the patients with sexual dysfunction, but no significant differences were noted in the patients without sexual dysfunction after TURP. CONCLUSIONS: More extended TURP can lead to a higher incidence of ED and retrograde ejaculation in BPH patients without sexual dysfunction before TURP. Patients with a lower volume of seminal vesicles after TURP may have a higher incidence of premature ejaculation.

Varicocele is associated with varicose veins: A population-based case-control study.

OBJECTIVE: To analyze the association between patients with varicocele and varicose veins in Taiwan. METHODS: Between 2001 and 2010, comprehensive data were analyzed on the characteristics of patients with varicocele and varicose veins in Taiwan through a retrospective, nationwide, population-based study. Data were obtained from the Taiwan National Health Insurance Research Database. A total of 2727 cases with varicose veins and 10 908 randomly selected controls were included in this study. Conditional logistic regression analyses were used to examine the association between varicose veins and varicocele. RESULTS: The prevalence of varicocele was 1.3% and 0.3% for cases (with varicose veins) and controls (without varicose vein), respectively (P < 0.001). Conditional logistic regression analysis showed that the odds ratio of being previously diagnosed with varicose veins for cases was 4.71 (95% confidence interval 2.87-7.89) when compared with controls after adjusting for age, diabetes, heart disease, chronic obstructive pulmonary disease, liver and kidney disease, and edema. Furthermore, the odds ratio was 5.96 (95% confidence interval 2.90-12.24), 4.76 (95% confidence interval 1.68-13.48) and 1.69 (95% confidence interval 0.30-9.55) in patients aged <50 years, 51-65 years and >65 years, respectively. In addition, the prevalence of male infertility was 15.1% for patients with varicocele and varicose veins, and 14.5% for patients with varicocele only, but no significant difference was observed. CONCLUSION: Our findings suggest an association between both varicocele and varicose veins. In addition, this association is higher in patients aged younger than 50 years. Evaluation of male patients with varicose veins for varicocele should be recommended.

Enhanced labor pain monitoring using machine learning and ECG waveform analysis for uterine contraction-induced pain.

OBJECTIVES: This study aims to develop an innovative approach for monitoring and assessing labor pain through ECG waveform analysis, utilizing machine learning techniques to monitor pain resulting from uterine contractions. METHODS: The study was conducted at National Taiwan University Hospital between January and July 2020. We collected a dataset of 6010 ECG samples from women preparing for natural spontaneous delivery (NSD). The ECG data was used to develop an ECG waveform-based Nociception Monitoring Index (NoM). The dataset was divided into training (80%) and validation (20%) sets. Multiple machine learning models, including LightGBM, XGBoost, SnapLogisticRegression, and SnapDecisionTree, were developed and evaluated. Hyperparameter optimization was performed using grid search and five-fold cross-validation to enhance model performance. RESULTS: The LightGBM model demonstrated superior performance with an AUC of 0.96 and an accuracy of 90%, making it the optimal model for monitoring labor pain based on ECG data. Other models, such as XGBoost and SnapLogisticRegression, also showed strong performance, with AUC values ranging from 0.88 to 0.95. CONCLUSIONS: This study demonstrates that the integration of machine learning algorithms with ECG data significantly enhances the accuracy and reliability of labor pain monitoring. Specifically, the LightGBM model exhibits exceptional precision and robustness in continuous pain monitoring during labor, with potential applicability extending to broader healthcare settings.

Factors affecting do-not-resuscitate decisions among patients with amyotrophic lateral sclerosis in Taiwan.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease. Usually, patients survive for approximately 2-4 years after the onset of the disease, and they often die of respiratory failure. This study examined the factors associated with signing a "do not resuscitate" (DNR) form in patients with ALS. This cross-sectional study included patients diagnosed with ALS between January 2015 and December 2019 in a Taipei City hospital. We recorded patients' age at disease onset; sex; presence of diabetes mellitus, hypertension, cancer, or depression; use of invasive positive pressure ventilator (IPPV) or non-IPPV (NIPPV); use of nasogastric tube (NG) or percutaneous endoscopic gastrostomy (PEG) tube; follow-up years; and number of hospitalizations. Data from 162 patients were recorded (99 men). Fifty-six (34.6%) signed a DNR. Multivariate logistic regression analyses revealed that the factors associated with DNR included NIPPV (OR = 6.95, 95% CI = 2.21-21.84), PEG tube feeding (OR = 2.86, 95% CI = 1.13-7.24), NG tube feeding (OR = 5.75, 95% CI = 1.77-18.65), follow-up years (OR = 1.13, 95% CI = 1.02-1.26), and number of hospital admissions (OR = 1.26, 95% CI = 1.02-1.57). The findings suggest that end-of-life decision making among patients with ALS may often be delayed. DNR decisions should be discussed with patients and their families during the early stages of disease progression. Physicians are advised to discuss DNR with patients when they can speak and to offer palliative care options.

Precision health in Taiwan: A data-driven diagnostic platform for the future of disease prevention.

"Precision medicine" has revolutionized how we respond to diseases by using an individual's genomic data and lifestyle and environment-related information to create an effective personalized treatment. However, issues surrounding regulations, medical insurance payments and the use of patients' medical data, have delayed the development of precision medicine and made it difficult to achieve "true" personalization. We therefore recommend that precision medicine be transformed into precision health: a novel and generalized platform of tools and methods that could prevent, manage, and treat disease at a population level. "Precision health," one of six core strategic industries highlighted in Taiwan's vision for 2030, uses various physiological data, genomic data, and external factors, to develop unique "preventative" solutions or therapeutic strategies. For Taiwan to implement precision health, it has to address three challenges: (1) the high-cost issue of precision health; (2) the harmonization issues surrounding integration and transmission of specimen and data; (3) the legal issue of combining information and communications technology (ICT) with Artificial Intelligence (AI) for medical use. In this paper, we propose an innovative framework with six recommendations for facilitating the development of precision health in Taiwan, including a novel model of precise telemedicine with AI-aided technology. We then describe how these tools can be proactively applied in early response to the COVID-19 crisis. We believe that precision health represents an important shift to more proactive and preventive healthcare that enables people to lead healthier lives.

Physician Palliative Education Associated With High Use of Hospice Care Service.

BACKGROUND: Taiwan's National Health Insurance provides coverage for palliative and hospice care. The following 10 types of diseases have been added to the National Health Insurance reimbursement regulation: end-stage cancer, motor neuron disease, organic psychosis, brain degeneration, heart failure, chronic airway obstruction diseases, other lung diseases, chronic liver disease and cirrhosis, acute renal failure, and chronic renal failure. OBJECTIVE: This study aimed to determine the association between physicians' palliative education and use of hospice care in hospitalized patients at the end of life. DESIGN AND SETTING: A cross-sectional study in a Taipei community hospital. PARTICIPANTS: Patients who died between 2014 and 2019 were identified. The deceased had at least 1 of the 10 diseases covered by health insurance were included. Hospice care services included hospice ward care and hospice shared care. This study included 2,661 individuals. In total, 972 (36.5%) patients used hospice care services. RESULTS: After adjusting for age, gender, and comorbidities, physicians' palliative education was found to significantly associated with the use of hospice care (OR: 14.38, 95% CI: 10.90-18.98). CONCLUSIONS: Physicians' palliative education was found to be an independent factor associated with higher use of hospice care. The findings suggest increasing palliative and hospice education among physicians so that they can ensure that their patients have high-quality end-of-life medical care in an aging society.

Predictors for lower urinary tract symptoms and the urinary specific quality of life in prostate cancer patients: One-year follow-up.

BACKGROUND: Prostate cancer (PCa) is the most frequently diagnosed cancer and is becoming a growing concern in global epidemiology. Quality of life of patients has become a major outcome for cancer care but limited study investigated quality of life of PCa patients. Our study is to investigate predictors for treatment outcomes of lower urinary tract symptoms (LUTS), nocturia, and the urinary specific quality of life (uQoL) in PCa patients one year following treatment. METHODS: A prospective study of 131 consecutive patients was conducted with outcome measurements before treatment, at 3 months, 6 months, and one year following therapy. We utilized the International Prostate Symptom Score questionnaire to collect data. Generalized estimating equations were performed to identify predictors for major outcomes of LUTS, nocturia, and uQoL. RESULTS: LUTS increased slightly over time, but nocturia and uQoL were improved from baseline to 12 months. Results of the interaction analysis indicated that patients with TNM stage 3 compared with those with stage 2 had a reduction in LUTS from diagnosis to 6 months. Patients who received surgery or radiation compared to hormone therapy had worse nocturia from diagnosis to 6 months compared to those of patients who received hormone therapy. Higher body mass index (BMI) decreased the uQoL from diagnosis to 3 months, and higher prostate-specific antigen (PSA) level deteriorated the uQoL from diagnosis to 12 months. CONCLUSION: TNM stage and BMI affected the LUTS. Patients undergone a prostatectomy or radiation therapy showed more frequency of nocturia, BMI and PSA were also risk factors for nocturia. Moreover, patients' age, BMI, and PSA affected uQoL. In such patients, we recommend close monitoring of patients' specific characteristics such as TNM stage, BMI, and PSA for a better quality of life.

Effectiveness of stress management in patients undergoing transrectal ultrasound-guided biopsy of the prostate.

BACKGROUND: To assess the utilization of stress management in relieving anxiety and pain among patients who undergo transrectal ultrasound (TRUS)-guided biopsy of the prostate. METHODS: Eighty-two patients admitted to a community hospital for a TRUS biopsy of the prostate participated in this case-controlled study. They were divided into an experimental group that was provided with stress management and a control group that received only routine nursing care. Stress management included music therapy and one-on-one simulation education. Before and after the TRUS biopsy, the patients' state-anxiety inventory score, pain visual analogue scale (VAS), respiratory rate, heart rate, and blood pressure were obtained. RESULTS: There were no differences in baseline and disease characteristics between the two groups. The VAS in both groups increased after the TRUS biopsy, but the difference in pre- and postbiopsy VAS scores was significantly lower in the experimental group (P=0.03). Patients in both groups experienced mild anxiety before and after the biopsy, but those in the experimental group displayed a significantly greater decrease in postbiopsy state-anxiety inventory score compared to the control group (P=0.02). CONCLUSION: Stress management can alleviate anxiety and pain in patients who received a TRUS biopsy of the prostate under local anesthesia.
