Summary
Urinary incontinence (UI) often persists in women with chronic cough, even after treatment. Older age, higher BMI, and less improvement in cough symptoms are linked to persistent UI.
Area of Science:
- Pulmonology
- Urology
- Clinical Medicine
Background:
- Urinary incontinence (UI) is a common comorbidity in female patients experiencing chronic cough.
- Factors influencing persistent UI and its clinical impact in this population require further elucidation.
Purpose of the Study:
- To investigate the prevalence and factors associated with persistent UI in female patients with chronic cough.
- To analyze patient-reported outcomes (PROs) related to UI and cough management over a 6-month period.
Main Methods:
- Longitudinal analysis of data from the Korean Chronic Cough Registry, including 206 female patients.
- UI status (persistent, resolved, absent) assessed at baseline and 6 months.
- Regression analyses to identify predictors of persistent UI and changes in PROs.
Main Results:
- Approximately 24.3% of patients had persistent UI at 6 months.
- Persistent UI was associated with older age (≥60 years) and higher BMI (≥25 kg/m²).
- Patients with persistent UI showed less improvement in cough hypersensitivity scores compared to those with resolved UI.
Conclusions:
- Persistent UI affects a significant portion of female chronic cough patients despite guideline-based management.
- Older age, higher BMI, and reduced improvement in cough hypersensitivity are key factors associated with persistent UI.
- Clinical attention is warranted for patients with persistent UI to address heterogeneity in treatment outcomes.

01:21Nursing Assessment of the Genitourinary System I: Health History
The genitourinary system is critical to maintaining fluid balance, waste elimination, and reproductive function. Nurses play a vital role in assessing this system, beginning with a thorough health history. This process involves gathering patient information, identifying risk factors, and recognizing symptoms of genitourinary disorders. Early detection is vital for timely interventions and management.1. Gathering Patient InformationA complete health history includes the patient’s personal,...
01:24Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features
Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
01:19Urodynamic Studies: Uroflowmetry
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...
01:24Chronic Obstructive Pulmonary Disease
COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Nursing management of Chronic Obstructive Pulmonary Disease (COPD) is crucial for providing thorough care and support to patients. Nurses play an integral role in this process through detailed assessment, careful planning, targeted interventions, and ongoing evaluation. Here's an overview of the critical steps in nursing management for COPD.

The nursing assessment of the genitourinary (GU) system involves a systematic inspection and palpation to identify abnormalities in the kidneys, bladder, and surrounding structures.InspectionMouth: Inspect for signs of kidney dysfunction, such as stomatitis (inflammation of the mouth) and ammonia breath, which may occur in advanced kidney disease due to the buildup of urea, breaking down into ammonia.Skin: Check for pallor, which could indicate anemia caused by kidney disease. Look for...
