Objective Seasonal influenza affects healthcare demand. However, the efficacy of anti-influenza drugs, particularly among young patients at a low risk of complications, has rarely been evaluated. Therefore, we evaluated the efficacy of anti-influenza drugs against seasonal influenza in healthy young and middle-aged adults. ⋯ Oseltamivir (300 mg/day for 5 days) showed the largest reduction in time to fever alleviation by -19.1 [95% confidence interval (CI): -29.4, -10.7] h compared with a placebo. Baloxavir marboxil (40 mg/day) reduced the time to symptom alleviation by -28.2 (95% CI: -42.7, -13.7) h, and peramivir (300 mg/day) administered by intravenous infusion for 1 day reduced the time to resumption of usual activities by -43.5 (95% CI: -72.8, -14.2) h. Conclusion Several pharmaceutical treatments were able to reduce the recovery time for fever and symptom alleviation and resumption of usual activities in young and middle-aged adults with seasonal influenza without increasing the risk of complications.

Review Meta Analysis
Prevalence of Drug Fever Among Cases of Nosocomial Fever: A Systematic Review and Meta-analysis.
Objective Drug fever is defined as a fever that temporally coincides with the start of a culprit drug and disappears after discontinuation of the drug. It is a common cause of nosocomial fever, which refers to a fever that develops beyond the first 48 h after hospital admission. However, the exact prevalence of drug fever among cases of nosocomial fever is unclear, as is the variation in prevalence depending on the clinical setting and most common causative drugs. ⋯ Only four studies reported the causative agents, and antibiotics were the most frequently reported. Conclusions The prevalence of drug fever is low in patients with nosocomial fever. Clinicians should recognize that drug fever is a diagnosis of exclusion, even in cases of nosocomial fever.

Meta Analysis
Seizure Control in Patients with Epilepsy During the COVID-19 Pandemic: A Systematic Review and Meta-analysis.
Objective To investigate seizure control in patients with epilepsy during the coronavirus disease 2019 (COVID-19) pandemic. Method A systematic review and meta-analysis was conducted, and the MEDLINE, EMBASE, CENTRAL, and ClinicalTrials.gov databases were comprehensively searched for relevant studies. Studies that reported seizure control in patients with epilepsy during the COVID-19 pandemic were included. ⋯ The pooled proportion of seizure worsening in the subgroup analysis was 18.9% (95% CI: 13.5-25.0; I2=96%; p<0.01). Conclusion Although the heterogeneity was high, our results showed a relatively high incidence of seizure worsening during the COVID-19 pandemic. During the COVID-19 pandemic, physicians should be aware of the likelihood of worsening seizures in patients with epilepsy.

Objective As the calreticulin (CALR) mutation frequency is significantly associated with essential thrombocythemia (ET) and primary myelofibrosis (PMF), this mutation may be an important biomarker in patients with ET and PMF. Methods We performed a literature search until April 2015 and obtained 21 relevant studies. The outcome was pooled as the effect size by using the Stata software program. ⋯ Moreover, the mutation ratio in Asian patients with PMF was lower (21%) than that in European-American patients (23%). A slight trend toward fibrotic transformation was found in ET with CALR mutations, whereas leukemic transformation was not significant in patients with ET or PMF with CALR mutations. Conclusion CALR mutations significantly influence the incident of ET as demonstrated by the meta-analysis.

Objective The impact of dialysis initiation on survival is still somewhat controversial. Given that race or ethnicity has been observed to be a predictor of mortality and the rate of progression of chronic kidney disease, we conducted a meta-analysis to investigate the effect of early vs. late dialysis initiation on mortality in East Asian populations. Methods All eligible cohort studies of target were selected from the MEDLINE (PubMed), EMBASE, The Cochrane Library and the Clinical Trials Registry databases from inception to October 2014. ⋯ Compared to late dialysis initiation, patients who received early dialysis initiation had a higher overall mortality risk (adjusted HR, 1.36; 95% CI, 1.0-1.85; p<0.05) in East Asian populations. In a subgroup analysis, baseline characteristic differences (adjusted HR, 2.0; 95%CI, 1.56-2.57; p<0.001), initial dialysis modalities (adjusted HR, 2.12; 95% CI, 1.72-2.62; p<0.001) and follow up duration (adjusted HR, 1.59; 95% CI, 1.19-2.12; p=0.002), demonstrated that the association between early dialysis initiation and mortality were significant. Conclusion A higher glomerular filtration rate (early) at the initiation of dialysis is associated with a higher all-cause mortality risk in East Asian populations.
