Infliximab Trough Levels Are Not Predictive of Relapse in Patients with IBD in Endoscopic Remission: A Multicenter Cohort Study.

BACKGROUND: Therapeutic drug monitoring (TDM) is important in optimizing use of biologics in inflammatory bowel diseases (IBD). However, the role of proactive TDM during remission remains uncertain. METHODS: This retrospective study included patients receiving infliximab (IFX) therapy at Massachusetts General Hospital or Erasmus University Medical Center. All eligible patients had completed induction phase of IFX and were in clinical and endoscopic remission. Our primary outcome was clinical relapse within 2 years after baseline. Multivariable regression models examined the association between infliximab trough levels during remission and relapse, need for IBD-related surgery or hospitalization. RESULTS: Our study cohort included 110 patients with IBD (72 CD, 38 UC) on IFX maintenance therapy. In total, 12 patients (10.9%) experienced relapse of disease over 2 years. The mean IFX trough level at baseline was 8.0 µg/mL (± 8.6) and did not differ between the institutions. 49.1% of patients had levels < 5 µg/mL and 2.7% had antibodies to infliximab at baseline. There was no difference in the mean IFX trough levels between patients who relapsed (7.5 µg/mL ± 3.7 µg/mL) over 24 months compared to those who did not (8.1 µg/mL ± 7.9 µg/mL, p = 0.815). On multivariable logistic regression analysis, IFX trough levels at baseline were not associated with relapse of disease over 24 months (OR 1.01, 95% CI 0.93-1.09, p = 0.856). CONCLUSION: This retrospective multicenter study provides evidence that IFX trough levels during quiescent disease do not predict relapse over 2 years, suggestive that proactive TDM in this setting is not warranted.

A Multi-Sensor Cane Can Detect Changes in Gait Caused by Simulated Gait Abnormalities and Walking Terrains.

Due to the increasing rates of chronic diseases and an aging population, the use of assistive devices for ambulation is expected to grow rapidly over the next several years. Instrumenting these devices has been proposed as a non-invasive way to proactively monitor changes in gait due to the presence of pain or a condition in outdoor and indoor environments. In this paper, we evaluated the effectiveness of a multi-sensor cane in detecting changes in gait due to the presence of simulated gait abnormalities, walking terrains, impaired vision, and incorrect cane lengths. The effectiveness of the instrumented cane was compared with the results obtained directly from a shank-mounted inertial measurement unit. Results from 30 healthy participants obtained while simulating gait abnormalities and walking over different terrains demonstrated the ability of the cane to reliably and effectively discriminate among these walking conditions. Moreover, the results obtained while walking with impaired vision and incorrect cane lengths indicate the ability of cane to detect changes in gait during these scenarios as well.

Multi-disciplinary proactive follow-up algorithm for patients with advanced NSCLC receiving afatinib.

PURPOSE: Afatinib is a standard first-line therapy for advanced EGFR-positive NSCLC. We implemented a pharmacist-led proactive follow-up algorithm to identify and manage early afatinib-related adverse events (AEs). METHODS: We conducted a retrospective chart review of all patients treated with afatinib after implementation of the algorithm at the Sunnybrook Odette Cancer Centre (Toronto, ON, Canada) from April 1, 2015 to July 31, 2016. Our in-house algorithm involved consultations in person and proactive pharmacist-led callbacks on days 5, 10, and 17. All AEs were graded and documented in real time and management based on toxicity grade was standardized. This study evaluated the impact of our algorithm on real-world AEs. RESULTS AND DISCUSSION: Thirty-three patients were identified and reviewed. Median follow-up was 248 days. All patients experienced at least one drug-related AE; 18.2% were grade 3/4. The most common AEs were diarrhea 87.9%, rash 81.8%, stomatitis 57.6%, and paronychia 45.5%. Median dose of afatinib was 40 mg daily; 51.5% of patients had ≥ 1 dose reduction and 6.3% discontinued afatinib due to AEs. Proactive calls by the pharmacist identified 36.5% of all drug-related AEs, 33.3% of grade 3/4 AEs, 58.1% of first drug-related AEs and identified two patients that were non-compliant. Only 3.2% of AEs were identified by an emergency room/urgent clinic visit. CONCLUSIONS: This proactive multi-disciplinary AE management algorithm resulted in a low rate of urgent assessments and discontinuation due to toxicity while maintaining afatinib at ideal dose, thus providing a useful tool for centers prescribing afatinib.

Effect analysis of implementing proactive monitoring on elderly stroke women with Escherichia coli infection caused by indwelling urinary catheter / 中国实用护理杂志

Objective To explore the control effect of proactive monitoring on senile stroke women with Escherichia coli infection caused by indwelling catheter.Methods From October 2011 to September 2012 elderly female stroke patients with indwelling urinary catheter were chosen in the department of neurology and were given proactive monitoring,which included the following:management of antibiotics has been humanized,urinary catheter care used first-cleaning and then disinfection method,pathogen monitoring professionals directly went to the bacteria room for obtaining information.The monitoring results were compared with those last year.Results The urinary Escherichia coli infection in monitoring popu-lations declined sharply,Escherichia coli infection rate reduced from 20.5％ to 3.6％.The urinary infection rate in hospitalized patients reduced from 10.8％ to 5.7％ respectively.The preventive application of an-tibacterial drugs greatly reduced from 70.0％ to 24.7％.The nursing staff all mastered the nursing method of the catheter.Conclusions To give proactive monitoring to senile stroke women with indwelling urinary catheter can control Escherichia coli and other bacteria induced urinary infection due to indwelling catheter significantly,demonstrate a deterrent effect on unreasonable application of antibiotics,which can be recommended to control other indwelling catheter induced urinary hospital infection.
