RESUMEN

INTRODUCTION: COVID-19 is associated with endothelial activation and systemic inflammation; consequently, statins can be used in its treatment as they have anti-inflammatory, antithrombotic, and profibrinolytic properties and may interfere with COVID-19 viral entry into cells through disruption of cell membrane lipid rafts. OBJECTIVE: We performed a meta-analysis of randomized clinical trials that compared statin therapy to placebo or to standard care in adult patients hospitalized for COVID-19. METHODS: We searched the MEDLINE, EMBASE, and Cochrane Library databases for all-cause mortality, hospitalization duration, and admission to the intensive care unit. RESULTS: Of the 228 studies reviewed, four studies were included, with a total of 1,231 patients, of whom 610 (49.5%) were treated with statins. There was no significant difference in all-cause mortality (odds ratio [OR] 0.96; 95% confidence interval [95%CI]: 0.61-1.51; p=0.86; I2=13%), duration of hospitalization (mean difference [MD] 0.21; 95%CI: -1.74-2.16; p=0.83; I2=92%), intensive care unit admission (OR= 3.31; 95%CI: 0.13-87.1; p=0.47; I2=84%), need for mechanical ventilation (OR= 1.03; 95%CI: 0.36-2.94; p=0.95; I2=0%), or increase in liver enzyme levels (OR= 0.58; 95%CI: 0.27-1.25; p=0.16; I2=0%) between patients treated with or without statin therapy. CONCLUSION: Our findings suggest that in adult patients hospitalized with COVID-19, statin therapy results in no difference in clinical outcomes when compared to outcomes by placebo or standard of care.

RESUMEN

PURPOSE OF REVIEW: To assess the effects of tezepelumab on quality of life (QoL) in patients with moderate-to-severe, uncontrolled asthma. RECENT FINDINGS: Tezepelumab improves pulmonary function tests (PFTs) and reduces the annualized asthma exacerbation rate (AAER) in patients with moderate-to-severe, uncontrolled asthma. We searched MEDLINE, Embase, and Cochrane Library from inception to September 2022. We included randomized controlled trials comparing tezepelumab versus placebo in patients aged ≥ 12 years with asthma on medium- or high-dose inhaled corticosteroids with ≥ 1 additional controller medication for ≥ 6 months and who had ≥ 1 asthma exacerbation in the 12 months before enrollment. We estimated effects measures with a random-effects model. Of 239 records identified, three studies were included, with a total of 1,484 patients. Tezepelumab significantly decreased biomarkers of T helper 2-driven inflammation, including blood eosinophil count (MD -135.8 [95% CI -164.37, -107.23]) and fractional exhaled nitric oxide (MD -9.64 [95% CI -13.75, -5.53]); improved PFTs, including pre-bronchodilator forced expiratory volume in 1 s (MD 0.18 [95% CI 0.08-0.27]); reduced the AAER (MD 0.47 [95% CI 0.39-0.56]); improved asthma-specific health-related QoL in the Asthma Control Questionnaire-6 (MD -0.33 [95% CI -0.34, -0.32]), Asthma Quality of Life Questionnaire for 12 Years and Older (MD 0.34 [95% CI 0.33, -0.35]), Asthma Symptom Diary (MD -0.11 [95% CI -0.18, -0.04]), and European Quality of Life 5 Dimensions 5 Levels Questionnaire (SMD 3.29 [95% CI 2.03, 4.55]) scores, although not clinically important; and did not change key safety outcomes, including any adverse event (OR 0.78 [95% CI 0.56-1.09]).

RESUMEN

OBJECTIVE: Ectopic pregnancy is a well-known complication following in vitro fertilization with embryo transfer; studies have questioned, however, whether there are risk factors that could be identified before the procedure. The objective of this study was to investigate the possible risk factors involved in ectopic pregnancy following in vitro fertilization. METHODS: Retrospective case-control study performed at an assisted reproduction clinic in Brazil. To select the control group, we used a 1:4 ratio. The study included 499 patients submitted to in vitro fertilization with clinical pregnancy. We collected the data from electronic records, between 2000-2019 and divided into: Group 1, ectopic pregnancy (n=90) and Group 2, intrauterine pregnancies (n=409). RESULTS: When comparing groups, the results observed were: Tubal factor infertility (35.6% vs. 21.1%, p=.005) (OR 2.0 [1.2-3.4], p=.004); Previous miscarriage history (15.1% vs. 7.1%, p<.05) (OR 2.0 [1.02-4.29], p=.044); Number of cleavage-stage embryo transfers (69.2% vs. 54.0 p=.028) (OR 1.9 [1.08-3.33], p=.025); Two or more embryos transferred (OR 2.5 [1.12-5.70], p=.025), all associated with greater ectopic pregnancy risk. Oocyte recipient patients were excluded from this analysis, but when included a difference was found when comparing the groups (9.4% (10/106) vs. 3.0% (13/434), p=.007), (OR 3.3 [1.41-7.98] p=.005); this result should be interpreted with caution because of the sample size. CONCLUSIONS: In high-risk patients, a single blastocyst transfer seems to be a reasonable approach to decrease the ectopic pregnancy risk.
