RESUMO
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]).

OBJECTIVE: To investigate risk factors for mortality in dengue. METHODS: We performed a systematic review and meta-analysis searching MEDLINE, Embase, SciELO, LILACS Bireme, and OpenGrey databases to identify eligible observational studies of patients with dengue, of both genders, aged 14 years or older, that analysed risk factors associated with mortality and reported adjusted risk measures with their respective confidence intervals (CIs). We estimated the pooled weighted mean difference and 95% CIs with a DerSimonian and Laird random-effects model. We assessed the methodological quality using the Newcastle-Ottawa Scale. RESULTS: Of 1,170 citations reviewed, 18 papers, with a total of 25,851 patients, were included in the systematic review and 12 in the meta-analysis. Severe hepatitis (OR 29.222, 95% CI 3.876-220.314), dengue shock syndrome (OR 23.575, 95% CI 3.664-151.702), altered mental status (OR 3.76, 95% CI 1.67-8.42), diabetes mellitus (OR 3.698, 95% CI 1.196-11.433), and higher pulse rate (OR 1.039, 95% CI 1.011-1.067) are associated with mortality in patients with dengue. All studies included were classified as having a high quality. CONCLUSIONS: Proper identification and management of these risk factors should be considered to improve patient outcomes and reduce the hidden burden of this neglected tropical disease. Future well-designed studies are needed to investigate the association of other clinical, radiological, and laboratorial findings with mortality in dengue, as well as to develop prognostic models based on the risk factors found in our study.

Precision medicine has helped identify several tumor molecular aberrations to be treated with targeted therapies. These therapies showed substantial improvement in efficacy without excessive toxicity in patients with specific oncogenic drivers with advanced cancers. In metastatic lung cancers, the implementation of broad platforms for molecular tumor sequencing has helped oncology providers identify oncogenic drivers linked with better outcomes when treated upfront with targeted therapies. Mesenchymal-epithelial transition factor (MET) alterations are present in up to 60% of non-small cell lung cancer and are associated with a poor prognosis. Capmatinib and tepotinib are currently the only two approved targeted therapies by the U.S. Food and Drug Administration (FDA) for patients with MET exon 14 skipping mutation. Several agents are being developed to tackle an unmet need in patients with MET alterations. Some of these agents are being used in combination with EGFR targeted therapy to mitigate resistance to EGFR inhibitor. These agents are poised to provide new hope for these patients.

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.

RESUMO
Abstract COVID-19 is a pandemic associated with systemic clinical manifestations. In this study, we aimed to present a narrative review on kidney involvement in COVID-19. Kidney involvement could be derived from direct cytopathic effects, immunological mechanisms, indirect effects on renal tissue through other mediators, and dysfunction or injury of other organs. The evolution of COVID-19 may be complicated with acute kidney injury (AKI) in a significant percentage of patients, and renal dysfunction seems to be associated with worse prognosis. Patients with chronic kidney disease (CKD) seem to be more susceptible to the severe forms of COVID-19. Patients with renal replacement therapy (RRT) are also a vulnerable population as consequence of their advanced age, underlying comorbidities, impaired immune response, and clustering in hemodialysis centers, with requirements for frequent contact with healthcare services. Kidney transplant patients may be at high-risk due to long-term immunosuppression and comorbidities, hence, managing immunosuppression is imperative. Lastly, renal replacement therapy may be required during COVID-19, and different modalities are discussed based on clinical findings and laboratorial aspects. Therefore, COVID-19 seems to affect kidney by different mechanisms, which contributes for AKI development and increases the severity of the disease. Also, patients with CKD and kidney transplant recipients are at higher risk for COVID-19 and mortality.
Resumo COVID-19 é uma pandemia associada a manifestações clínicas sistêmicas. Neste estudo, apresenta-se revisão narrativa acerca do envolvimento renal na COVID-19. Envolvimento renal parece ser relacionado a efeitos citopáticos diretos, mecanismos imunológicos, efeitos indiretos de outros mediadores no tecido renal, além de disfunção e lesão de outros órgãos. A evolução da COVID-19 pode ser complicada por lesão renal aguda (LRA) em percentual significativo dos pacientes, e a disfunção renal parece ser associada a pior prognóstico. Pacientes com doença renal crônica (DRC) parecem ser mais suscetíveis a formas severas da COVID-19. Pacientes em terapia de substituição renal (TSR) contínua também constituem população vulnerável em razão de idade avançada, comorbidades subjacentes, resposta imune disfuncional e aglomeração em unidades de diálise, com necessidade de visitas frequentes aos serviços de saúde. Pacientes transplantados renais podem estar em alto risco dadas imunossupressão a longo prazo e comorbidades; assim, o manejo da imunossupressão é mandatório. Finalmente, TSR pode ser necessária durante a COVID-19, e diferentes modalidades são discutidas conforme manifestações clínicas e aspectos laboratoriais. Assim, COVID-19 parece acometer os rins por diferentes mecanismos, os quais contribuem para o desenvolvimento de LRA e aumento da severidade da doença. Ainda, pacientes com DRC e transplantados renais apresentam elevado risco para desenvolvimento de COVID-19 e de mortalidade.
