Comparative efficacy and safety of systemic antifungal agents for candidemia: a systematic review with network meta-analysis and multicriteria acceptability analyses.

AIM: Invasive candidiasis is the most common fungal infection in patients attending health services and is associated with high mortality rates and prolonged hospital stay. The aim of this review was to evaluate and compare efficacy and safety of antifungal agents for the treatment of candidemia. METHODS: A systematic review with network meta-analysis (NMA), surface under the cumulative ranking analysis (SUCRA) and stochastic multicriteria acceptability analyses (SMAA) was performed (PROSPERO-CRD42020149264). Searches were conducted in PubMed and Scopus (Nov-2021). Randomised controlled trials evaluating the effect of oral antifungals (any dose or regimen) on mycological cure, discontinuation rates and adverse events were included. RESULTS: Overall, 13 trials (n=3632) were analysed. There were no significant differences between therapies for the efficacy outcomes; however, caspofungin (50-150 mg), rezafungin (200-400 mg) and micafungin (100-150 mg) had higher rates of clinical and mycological responses (SUCRA overall response >60%) and were considered the most promising therapies. Fluconazole (400 mg) rated worst for overall response (17%). Rezafungin (200-400 mg) and micafungin (100 mg) were associated with lower discontinuation rates (<40%). Conventional amphotericin B (0.6-0.7 mg/kg) was more likely to be discontinued (odds ratio [OR] 0.08; 95% credibility interval [CrI] 0.00-0.95 vs. caspofungin 150 mg) and may impair liver function (87%). CONCLUSION: Echinocandins are recommended as first-line treatments for invasive candidiasis following a priority order of caspofungin then micafungin. Rezafungin, an echinocandin under development, represents a potential option that should be further investigated. Azoles and liposomal amphotericin B can be used as second-line treatments in cases of fungal resistance or hypersensitivity.

Influence of foods and nutrients on COVID-19 recovery: A multivariate analysis of data from 170 countries using a generalized linear model.

BACKGROUND & AIMS: COVID-19 is an emergency public health problem of global importance. This study aimed to investigate the effect of foods and nutrients as complementary approaches on the recovery from COVID-19 in 170 countries, especially considering the complexity of the disease and the current scarcity of active treatments. METHODS: A retrospective study was performed using the Kaggle database, which links the consumption of various foods with recovery from COVID-19 in 170 countries, using multivariate analysis based on a generalized linear model. RESULTS: The results showed that certain foods had a positive effect on recovery from COVID-19: eggs, fish and seafood, fruits, meat, milk, starchy roots, stimulants, vegetable products, nuts, vegetable oil and vegetables. In general, consumption of higher levels of proteins and lipids had a positive effect on COVID-19 recovery, whereas high consumption of alcoholic beverages had a negative effect. In developed countries, where hunger had been eradicated, the effect of food on recovery from COVID-19 had a greater magnitude than in countries with a higher global hunger index (GHI), where there was almost no identifiable effect. CONCLUSION: Several foods had a positive effect on COVID-19 recovery in developed countries, especially food groups with a higher content of lipids, proteins, antioxidants and micronutrients (e.g., selenium and zinc). In countries with extreme poverty (high GHI), foods presented little effect on recovery from COVID-19.

Systematic review with meta-analysis of the accuracy of diagnostic tests for COVID-19.

OBJECTIVE: To collate the evidence on the accuracy parameters of all available diagnostic methods for detecting SARS-CoV-2. METHODS: A systematic review with meta-analysis was performed. Searches were conducted in Pubmed and Scopus (April 2020). Studies reporting data on sensitivity or specificity of diagnostic tests for COVID-19 using any human biological sample were included. RESULTS: Sixteen studies were evaluated. Meta-analysis showed that computed tomography has high sensitivity (91.9% [89.8%-93.7%]), but low specificity (25.1% [21.0%-29.5%]). The combination of IgM and IgG antibodies demonstrated promising results for both parameters (84.5% [82.2%-86.6%]; 91.6% [86.0%-95.4%], respectively). For RT-PCR tests, rectal stools/swab, urine, and plasma were less sensitive while sputum (97.2% [90.3%-99.7%]) presented higher sensitivity for detecting the virus. CONCLUSIONS: RT-PCR remains the gold standard for the diagnosis of COVID-19 in sputum samples. However, the combination of different diagnostic tests is highly recommended to achieve adequate sensitivity and specificity.

Five-year survival analysis and predictors of death in HIV-positive serology patients attending the Military Hospital of Nampula, Mozambique.

An observational retrospective study was conducted over a 5-year period to assess survival and predictors of death in people with HIV-positive serology undergoing antiretroviral treatment with first-line regimens at the Military Hospital of Nampula, Mozambique. We collected data from 332 patient records. Kaplan-Meier boundary product estimator, log-rank, Gehan-Breslow, Tarone-Ware, time-dependent Cox models and estimates of hazard ratios (HR), with 95% confidence interval (CI) were calculated. Meantime survival for females and males was 54.8 months [95% CI 50.32-55.40] and 49.7 months [95% CI 45.89-53.53], respectively. Cox regressions indicated higher death rates significantly or potentially associated with: male sex (HR = 1.3; [95% CI 0.7-2.39]); suspected diagnosis reported only by the physician (HR = 3.6; [95% CI 1.8-7.4]); disease stages III (HR=1.2 [95% CI 0.3-3.6]) or IV (HR 1.4 [95% CI 0.4-5.8]); first TCD4+ lymphocyte count lower than 350 cells per ml (HR = 3.2; [95% CI 0.9-11.2]) or between 350-500 cells per ml (HR = 1.3; [95% CI 0.3-5.8]); or do not present cells count (HR = 3.6; [95% CI 1.2-10.2]). The above variables were significant for HIV prognosis and as predictors of death and should be considered in the clinical care of these patients.
