Neuropsychiatric Manifestations and Cognitive Decline in Patients With Long-Standing Lyme Disease: A Scoping Review.

Lyme disease (LD), or Lyme borreliosis, is a vector-borne disease that is caused by the transmission of the bacterium Borrelia burgdorferi through a tick bite. The symptoms of LD can persist in individuals chronically, even after the treatment and resolution of the initial infection. These symptoms include various neuropsychiatric manifestations and cognitive decline. The purpose of this review was to report the neuropsychiatric manifestations, cognitive decline, and effects of a delayed diagnosis on symptom severity in patients with long-standing LD (LSLD). A scoping review was conducted utilizing the electronic databases Embase, Ovid Medical Literature Analysis and Retrieval System Online (MEDLINE), and Web of Science. A total of 744 articles were retrieved and considered for inclusion. After a rigorous screening process, 10 articles that met the inclusion criteria for this review were included (i.e., reported neuropsychiatric manifestations and cognitive decline in patients with LSLD and the effects of a delayed diagnosis). Neuropsychiatric manifestations in the patients consisted of suicidal ideation, homicidal tendencies, extreme anger, depressive symptoms, aggression, and anxiety. Cognitive symptoms included dysfunctions in working memory, verbal learning/memory, non-verbal learning/memory, alertness, visuoconstructive, and frontal executive functioning. A delayed LD diagnosis increased symptom severity in most patients. The findings of this review indicate that neuropsychiatric and cognitive symptoms tend to present for a chronic period, even after disease recovery. Although researchers have established a link between a delayed LD diagnosis and increased symptom severity, LSLD is often an overlooked diagnosis in patients with neuropsychiatric symptoms and cognitive decline. More research is needed to compare the time to diagnosis and symptom severity in patients with LSLD.

The 2018 Global Point Prevalence Survey of antimicrobial consumption and resistance in 47 Canadian hospitals: a cross-sectional survey.

BACKGROUND: Patient-level surveillance of antimicrobial use (AMU) in Canadian hospitals empowers the reduction of inappropriate AMU and was piloted in 2017 among 14 hospitals in Canada. We aimed to describe AMU on the basis of patient-level data in Canadian hospitals in 2018 in terms of antimicrobial prescribing prevalence and proportions, antimicrobial indications, and agent selection in medical, surgical and intensive care wards. METHODS: Canadian adult, pediatric and neonatal hospitals were invited to participate in the standardized web-based cross-sectional Global Point Prevalence Survey of Antimicrobial Consumption and Resistance (Global-PPS) conducted in 2018. An identified site administrator assigned all wards admitting inpatients to specific surveyors. A physician, pharmacist or nurse with infectious disease training performed the survey. The primary outcomes were point prevalence rates for AMU over the study period regarding prescriptions, indications and agent selection in medical, surgical and intensive care wards. The secondary outcomes were AMU for resistant organisms and practice appropriateness evaluated on the basis of quality indicators. Antimicrobial consumption is presented in terms of prevalence and proportions. RESULTS: Forty-seven of 118 (39.8%) hospitals participated in the survey; 9 hospitals were primary care centres, 15 were secondary care centres and 23 were tertiary or specialized care centres. Of 13 272 patients included, 33.5% (n = 4447) received a total of 6525 antimicrobials. Overall, 74.1% (4832/6525) of antimicrobials were for therapeutic use, 12.6% (n = 825) were for medical prophylaxis, 8.9% (n = 578) were for surgical prophylaxis, 2.2% (n = 143) were for other use and 2.3% (n = 147) were for unidentified reasons. A diagnosis or indication was documented in the patient's file at the initiation for 87.3% (n = 5699) of antimicrobials; 62.9% (n = 4106) of antimicrobials had a stop or review date; and 72.0% (n = 4697) of prescriptions were guided by local guidelines. INTERPRETATION: Overall, three-quarters of AMU was for therapeutic use across participating hospitals. Canadian hospitals should be further incentivized to create and adapt local guidelines on the basis of recent antimicrobial resistance data.

Trastuzumab beyond progression for HER2 positive metastatic breast cancer: progression-free survival on first-line therapy predicts overall survival impact.

Trastuzumab beyond first progression in the metastatic setting has been adopted based on limited data suggesting improved outcomes compared to second-line chemotherapy alone although predictive factors for preferential benefit remain elusive. We conducted a retrospective review of all patients receiving trastuzumab for HER2 + metastatic disease between Jan 1, 1999-June 15, 2011. Univariate and time to event analyses described treatment and survival patterns. Median duration of each line of therapy and overall survival times for covariates, including treatment era (pre versus post Jan 1, 2005), lines of trastuzumab-based therapy (1 versus 2 versus 3 + ), first-line chemotherapy partner (docetaxel/paclitaxel versus other) and median exposure to first-line trastuzumab-based therapy (=/> versus < cohort median) were estimated. A total of 119 patients received a median of two lines of trastuzumab-based therapy (range 1-8). Median overall survival was 21.8 months (95% CI = 14.5-27.1 m), by era was 15.6 m (95% CI = 9.7-24.8 m) versus 26.1 m (95% CI = 20.0-39.3 m; p = 0.11) and by lines of trastuzumab-based therapy received was 10.6 m (95% CI = 5.3-17.4 m) versus 13.9 m (95% CI = 9.5-27.6 m) versus 32.5 m (95% CI = 25-49.4 m) (p = 0.0014). Median overall survival was significantly longer for those receiving taxanes with trastuzumab compared to other first line partners (26.1 m, 95% CI = 17.8-31.4 m versus 14.5 m, 95% CI = 9.4-21.9 m, p = 0.02). Median overall survival with duration of first-line trastuzumab-based therapy =/> cohort median was 31.9 m (95% CI = 26.2-52.2 m) versus 10.3 m for shorter durations (95% CI = 6.9-15.6 m; p < 0.0001). Our observations support progression-free survival on first-line trastuzumab-based therapy as a clinically relevant predictive factor for overall survival benefit with the adoption of a trastuzumab beyond progression treatment strategy.
