Associations of Pap test utilisation with comorbidity and functional impairment among middle-aged non-Hispanic black women in the USA: a cross-sectional analysis of the 2018 BRFSS data.

OBJECTIVES: Limited evidence exists on the association of Pap test utilisation with comorbidity and functional impairment among middle-aged non-Hispanic black (NHB) women in the USA. We aimed to assess whether middle-aged NHB women with a higher burden of comorbidity and functional impairment have a lower rate of Pap test utilisation. DESIGN: Nationwide cross-sectional survey in the USA. SETTING: 2018 Behavioral Risk Factor Surveillance System. PARTICIPANTS: 6359 middle-aged NHB women. EXPOSURES AND OUTCOME: The primary exposures were comorbidity and functional impairment. The outcome of interest was whether a woman reported having a Pap test in the last 3 years. DATA ANALYSIS: We fit unadjusted and multivariable logistic regression models to calculate ORs and 95% CI for comorbidity and functional impairment. Sensitivity analysis was restricted to women without a history of hysterectomy or cancer. We added interaction terms between exposures and age, as well as lifestyle indicators. RESULTS: Of the 6359 women, 4141 (65.1%) had comorbidity and 2429 (38.2%) had functional impairment. Middle-aged NHB women with comorbidity (≥2 vs 0, aOR=0.72, 95% CI=0.61 to 0.85, p trend<0.01) or functional impairment (≥2 vs 0, aOR=0.69, 95% CI=0.57 to 0.83, p trend<0.01) had a lower rate of Pap test utilisation compared with healthier counterparts, regardless of histories of hysterectomy and prior cancer. The analyses for age and lifestyle indicators subgroup difference indicated no statistically significant effect (p interaction>0.05). However, the magnitude of these associations was stronger among women with adverse lifestyle factors (eg, comorbidity ≥2 v.s. 0, aOR=0.53, 95% CI=0.40, to 0.71; functional impairment ≥2 v.s. 0, aOR=0.35, 95% CI=0.16, to 0.72 among binge drinkers). CONCLUSION: Comorbidity or functional impairment could be a potential barrier to Pap test utilisation among middle-aged NHB women in the USA. Our study highlights the importance of implementing targeted intervention programmes and prioritised health resource allocation to promote Pap test utilisation. Cohort studies with clear temporality and indicators reflecting disease severity will be essential for further understanding this association.

Preliminary analysis of stimulation parameters for sacral neuromodulation in different indications: a multicenter retrospective cohort study from China.

BACKGROUND: Sacral neuromodulation (SNM) is an effective approach for treating lower urinary tract dysfunction (LUTD), and stimulation programming is essential for successful treatment. However, research on SNM programming for various indications is limited. Thus, the authors aimed to determine whether there were differences in the stimulation parameters for different SNM indications and the appropriate programming recommendations. MATERIALS AND METHODS: Clinical data were retrospectively collected from patients with LUTD who underwent SNM and completed internal pulse generator implantation. The parameters with the highest patient satisfaction or the most symptom improvement during the test period were considered optimal and used to set the programming after internal pulse generator implantation. RESULTS: After screening, 282 patients were enrolled and categorized into four groups based on the following indications: refractory overactive bladder (OAB) ( n =61), neurogenic lower urinary tract dysfunction (nLUTD) ( n =162), interstitial cystitis/painful bladder syndrome (IC/BPS) ( n =24), and idiopathic nonobstructive urinary retention (NOUR) ( n =35). When analyzing the optimal stimulus parameters, disparities in the stimulation amplitude and pulse frequency were noted among the four groups. The stimulation amplitude in the nLUTD group was higher than that in the idiopathic NOUR group ( P =0.013). Differences in pulse frequency were observed between the refractory OAB and nLUTD groups ( P <0.001) and between the refractory OAB and idiopathic NOUR groups ( P =0.001). No differences in the electrode configuration or pulse width settings existed among the four groups. CONCLUSIONS: The stimulation parameters for SNM varied among the different indications. For the initial programming of stage I, most patients are recommended to start with stimulation amplitudes below 2 V, although patients with nLUTD may benefit from higher amplitudes. A standard pulse width of 210 µs is recommended for all patients. However, for individuals experiencing nLUTD or idiopathic NOUR, the pulse frequency can begin above the standard 14 Hz but not exceed 50 Hz.
