Impact on quality of life in multiple sclerosis patients: Which urinary symptoms are to blame?

AIM: To evaluate the correlation between the Expanded Disability Status Scale (EDSS) in multiple sclerosis (MS) subjects, and the severity of lower urinary tract symptoms (LUTS), the bother caused by these symptoms and subjects' quality of life (QoL). MATERIAL AND METHODS: This cross-sectional study included 50 subjects with persistent LUTS secondary to MS who were recruited from the registry of a national NGO, between October 2017 and November 2019. Subjects with a history of any disease besides MS that could otherwise explain the presence of LUTS, as well as those with other neurological conditions were excluded. Information including MS duration, subjects' EDSS, voiding and storage LUTS, voiding symptoms' subscore of the International Prostate Symptom Score (IPSS-V), Overactive Bladder Symptom Scores (OABSS), Urinary Bothersome Questionnaire in Multiple Sclerosis (UBQMS), and urologic QoL (SF-Qualiveen) was gathered. Correlations between these scores were assessed using Spearman's bivariate correlations. Wilcoxon's signed rank test was used to evaluate the difference of impact between voiding and storage LUTS on bother of subjects. RESULTS: The median disease duration was 7±5.8years and the predominant lower urinary symptom was urgency (82%). Median OABSS and IPSS-V were respectively 8±3.8 and 8±3. Subjects were significantly more bothered from storage than voiding symptoms (2 vs. 1.6; P=0.03), and their QoL was directly affected by storage LUTS. Urgency urinary incontinence had the highest positive correlation with SFQ (r=0.542; P<0.01). MS duration and urologic QoL measured by SF-Q were negatively correlated (r=-0.345; P=0.01). CONCLUSION: In MS patients with LUTS, urologic QoL is mainly affected by storage urinary symptoms. Physicians should use a holistic approach to reduce the risk of complications in these patients, by controlling both voiding and storage symptoms, in particular urgency urinary incontinence that mostly affects patient's QoL.

Safety in the preparation of cytotoxic drugs: How to integrate gravimetric control in the quality assurance policy?

PURPOSE: We present the way to integrate gravimetric control (GC) in a centralized preparation of cytotoxic drugs unit. Two different modalities are described. In the first strategy, the balance is located inside the isolator, whereas in the second, it is located outside in order to remove many technical and ergonomic constraints. These two modalities are compared in terms of benefits and limits. METHODS: GC consists in comparing the observed weight variation with the expected weight variation using a precision balance. According to the B-in strategy, this variation is directly attributable to the weight of the cytotoxic solution injected, whereas with the B-out strategy, the weight of various additional components must be taken into account. RESULTS: Five hundred and seventy-seven preparations have been weighed. For "B-in" strategy, the 95% confidence interval is [1.02-1.14%] and every preparation is below the threshold of 5%. For "B-out" strategy, the 95% confidence interval is [2.34-2.63%] and 94% of preparations are below the threshold of 5%. B-in strategy is distinctly more precise than B-out strategy and can be applied to all preparations. However, B-out strategy is a feasible option in practice and enables the detection of an important mistake. All in all, results obtained from B-out strategy can be considered as a quality indicator in the production line. CONCLUSION: Results of GC are helpful in the final step of release, which the pharmacist is responsible for. Many contributions in the quality assurance policy could justify using of GC in every unit.
