Leukotriene receptor antagonists as add-on therapy to antihistamines for urticaria: Systematic review and meta-analysis of randomized clinical trials.

BACKGROUND: The benefits and harms of adding antileukotrienes to H1 antihistamines (AHs) for the management of urticaria (hives, itch, and/or angioedema) remain unclear. OBJECTIVE: We sought to systematically synthesize the treatment outcomes of antileukotrienes in combination with AHs versus AHs alone for acute and chronic urticaria. METHODS: As part of updating American Academy of Allergy, Asthma & Immunology and American College of Allergy, Asthma, and Immunology Joint Task Force on Practice Parameters urticaria guidelines, we searched Medline, Embase, Central, LILACS, WPRIM, IBECS, ICTRP, CBM, CNKI, VIP, Wanfang, US Food and Drug Administration, and European Medicines Agency databases from inception to December 18, 2023, for randomized controlled trials (RCTs) evaluating antileukotrienes and AHs versus AHs alone in patients with urticaria. Paired reviewers independently screened citations, extracted data, and assessed risk of bias. Random effects models pooled effect estimates for urticaria activity, itch, wheal, sleep, quality of life, and harms. The GRADE approach informed certainty of evidence ratings. The study was registered at the Open Science Framework (osf.io/h2bfx/). RESULTS: Thirty-four RCTs enrolled 3324 children and adults. Compared to AHs alone, the combination of a leukotriene receptor antagonist with AHs probably modestly reduces urticaria activity (mean difference, -5.04; 95% confidence interval, -6.36 to -3.71; 7-day urticaria activity score) with moderate certainty. We made similar findings for itch and wheal severity as well as quality of life. Adverse events were probably not different between groups (moderate certainty); however, no RCT reported on neuropsychiatric adverse events. CONCLUSION: Among patients with urticaria, adding leukotriene receptor antagonists to AHs probably modestly improves urticaria activity with little to no increase in overall adverse events. The added risk of neuropsychiatric adverse events in this population with leukotriene receptor antagonists is small and uncertain.

Current Status of Burnout in Canadian Radiology.

Burnout is a healthcare concern affecting physicians around the world. Physicians experiencing burnout tend to display signs of emotional exhaustion, depersonalization, and low personal accomplishment. Ongoing burnout trends have posed numerous challenges to Canadian physicians, notwithstanding the added complexity of the COVID-19 pandemic's impact in recent years. In particular, Canadian radiologists frequently reported experiencing high rates of burnout. This review aims to examine prominent factors affecting burnout in Canadian radiologists and summarize the impact of recent trends. In doing so, the overall wellbeing of Canadian radiologists can be assessed, and strategies for improvement can be discussed as the Canadian healthcare system prepares for new challenges of increasing demand and pressures.

Barriers to Screening At-risk Populations in Canada.

Cancer screening is invaluable for early detection of disease, including for breast and lung cancer. Through early detection, cancer treatment can be commenced prior to the development of advanced stage disease, significantly reducing morbidity and mortality. However, eligible patients may face barriers when accessing screening services, and some groups may be more disproportionately affected than others. This review aims to describe some of the most prominent barriers that at-risk populations may face when accessing image-based cancer screening services in Canada. Characterizing these barriers would be helpful in determining the best strategies to increase uptake to these screening services and, consequently, improve health equity.

Phenotyping the Association between Nocturia and Hypertension: A Systematic Review and Meta-Analysis.

PURPOSE: The association between nocturia and hypertension has been widely reported yet remains poorly characterized, precluding a more refined understanding of blood pressure as it relates to the clinical urology setting. We synthesized current evidence on the relationship between nocturia and hypertension as a function of nocturia severity, age, gender, race, body mass index and diuretic use. MATERIALS AND METHODS: We searched PubMed®, EMBASE® and Cochrane databases for studies published up to May 2020. Random effects meta-analyses were performed to identify pooled odds ratios for nocturia given the presence of hypertension. Meta-regression and subgroup analyses were performed to identify differences across study samples. RESULTS: Of 1,193 identified studies, 25 met the criteria for inclusion. The overall pooled OR for the association of nocturia with hypertension was 1.25 (95% CI 1.21-1.28, p <0.001). Pooled estimates were 1.20 (1.16-1.25, p <0.001) and 1.30 (1.25-1.36, p <0.001) using a 1-void and 2-void cutoff for nocturia, respectively (p <0.001 between cutoffs). The association was more robust in patient-based (1.74 [1.54-1.98], p <0.001) vs community-based (1.24 [1.24-1.29], p <0.001) study samples (p <0.001). The association was stronger in females compared to males (1.45 [1.32-1.58] vs 1.28 [1.22-1.35], p <0.001), and Black (1.56 [1.25-1.94]) and Asian (1.28 [1.23-1.33]) vs White subgroups (1.16 [1.08-1.24]; p <0.05 for both). No effect was observed for age or body mass index. Evidence on diuretics was limited. CONCLUSIONS: Hypertension is associated with a 1.2-fold to 1.3-fold higher risk of nocturia. This association is more robust at a higher nocturia cutoff, in patient-based study samples, among females and in Black and Asian patients, but unrelated to age or body mass index.

Impact of neuraxial analgesia on outcomes following radical cystectomy: A systematic review.

Radical cystectomy (RC) is associated with significant morbidity. Neuraxial analgesia is recommended by enhanced recovery after surgery guidelines, but largely supported by evidence extrapolated from colorectal surgery outcomes. We synthesized current evidence regarding short- and long-term outcomes associated with neuraxial analgesia versus patient controlled non-neuraxial analgesia following RC. PubMed, Embase, and Cochrane databases were searched for relevant studies published up to May 2020. Studies reporting complications, length of stay (LOS), pain score, opioid usage within 72 hours, overall survival, cancer-specific survival, and recurrence rate were included. Of 550 identified studies, 9 met criteria for inclusion. Four studies demonstrated a higher percentage of 90-day complications in the neuraxial analgesia cohort. Out of 6 studies reporting information regarding LOS, 4 demonstrated no improvement in LOS in the neuraxial cohort. A reduction in 72 hours post-RC opioid usage was observed in 2 out of 3 studies with available data. Information regarding post-RC pain scores were variable up to 3 days post-RC. One out of 2 studies with available data reported a significant association between neuraxial analgesia and an earlier time to recurrence. No significant associations were seen with respect to overall survival or cancer-specific survival. A majority of low-to-moderate quality evidence demonstrates neuraxial analgesia is associated with a higher rate of complications, variable information regarding pain control, no improvements in LOS, and no significant association with long-term oncological outcomes. Further research regarding the incorporation of nonopiate-based analgesic modalities into RC ERAS protocols is warranted.
