Noise-induced hearing loss is one of the most prevalent causes of hearing impairment and occupational diseases. Although multiple factors lead to noise-induced hearing loss, prevention and protection strategies remain limited. Studies in the past decade have employed antioxidants, especially N-acetyl-cysteine, to prevent noise-induced hearing loss. Therefore, this systematic review and meta-analysis of randomized controlled trials evaluated the effect of N-acetyl-cysteine on the prevention of noise-induced hearing loss. ⋯ The present review and meta-analysis recommends that N-acetyl-cysteine may be considered as an option for protective therapy for noise-induced hearing loss. Nonetheless, larger randomized controlled trials are requisite for further investigation and verification.

The role of low-dose aspirin combined with low-molecular-weight heparin (LMWH) in the treatment of preeclampsia (PE) remains unclear. We aimed to assess the efficacy and safety of low-dose aspirin combined with LMWH in PE treatment, to provide evidence for clinical PE management. ⋯ Low-dose aspirin combined with LMWH treatment of PE may be advantageous to improve blood pressure, 24-hour proteinuria and coagulation function, and it may reduce the adverse reactions in pregnant women without increasing adverse perinatal outcomes.

Influenza virus infection is associated with high morbidity and mortality, and so additional therapeutic strategies to reduce the burden for healthcare systems are needed. Statins, by virtue of their anti-inflammatory and immunomodulatory effects, have been hypothesized as capable of influencing the host's response against the influenza virus. The aim of this meta-analysis was to assess the effect of ongoing statin treatment on susceptibility to influenza virus infection and on influenza-associated mortality. ⋯ Reduced influenza prevalence and increased survival from influenza infection was observed in patients on ongoing statin treatment. Further research is needed to define the possible role of statins as adjunctive therapy in patients with influenza infection.

There are limited studies exploring the effects of n-3 PUFA supplementation on pregnancy outcomes. The goal of this study was to review relevant studies in order to determine the effect of n-3 polyunsaturated fatty acid (n-3 PUFA) supplementation on pregnancy outcomes based on eligible randomized controlled trials (RCTs). ⋯ The available evidence shows that n-3 PUFA is not beneficial in reducing the incidence of maternal pregnancy outcomes such as gestational diabetes mellitus and hypertension; but it is beneficial to neonatal health such as decreasing the incidence of preterm delivery and low birthweight and increasing birth weight and birth length.

No early treatment intervention for COVID-19 has proven effective to date. We systematically reviewed the efficacy of hydroxychloroquine as early treatment for COVID-19. ⋯ Hydroxychloroquine was not efficacious as early treatment for COVID-19 infections in RCTs with low to very low quality of evidence for all outcomes. More RCTs are needed to elucidate the efficacy of hydroxychloroquine as early treatment intervention.
