Exponential-like infection growth leading to peaks (denoted by inflection points [IP] or turning points) is usually the hallmark of infectious disease outbreaks, including coronaviruses. To determine the IPs of the novel coronavirus (COVID-19), we applied the item response theory model to detect phase transitions for each country/region and characterize the IP feature on the temporal bar graph (TBG). ⋯ Temporal visualization is recommended for researchers in future relevant studies (e.g., the evolution of keywords in a specific discipline) and is not merely limited to the IP search in COVID-19 pandemics as we did in this study.

Nonalcoholic non-virus-related hepatocellular carcinoma (NANV-HCC) is considered to occur in steatotic livers; however, emerging evidence indicates that a subset of NANV-HCC occurs in nonsteatotic livers. Currently, little information is available regarding this subset. This study sought to provide the clinical and pathological features of NANV-HCC in nonsteatotic livers. ⋯ NANV-HCC with a nonsteatotic liver was independently associated with a shorter disease-free survival (DFS) (hazard ratio [HR] 2.14; 95% confidence interval [CI] 1.21-3.80; P = .009) and a shorter overall survival (OS) (HR 2.79; 95% CI 1.27-6.16; P = .01) than NANV-HCC with a steatotic liver. The absence of steatosis in the liver is independently associated with shorter DFS and OS in patients with NANV-HCC. Our findings indicate that nonsteatotic liver can be a surrogate phenotype of aggressive NANV-HCC.

Meta Analysis
Programmed intermittent epidural bolus in parturients: A meta-analysis of randomized controlled trials.
To evaluate the efficacy and safety of programmed intermittent epidural bolus (PIEB) in parturients. ⋯ PIEB is a good alternative for labor analgesia with better analgesic effect, maternal and infant outcome.

Randomized Controlled Trial
Usefulness of the additional contrast agents to identify offending nerve root in selective nerve root block.
It is hypothesized that if it is confirmed that the pain caused by the injection needle coincides with the lower leg radiating pain(LLRP) that the patient mainly complains of, then the contrast agents may be used less. This study aims to understand if the identification of lancinating identical pain in the procedure could replace the use of contrast agents that causes additional pain provocation using control arm of randomized clinical trial. This retrospective study included 165 patients who met exclusion criteria from among patients who underwent Selective nerve root block for the treatment of LLRP. ⋯ At 12 weeks after injection, there was a statistically significant difference, but they were below Minimum Clinical Important Difference, bearing little clinical implications. There was no statistically significant difference between the 2 groups in Owestry Disability Index, Rolland-Morris Disability Questionnair, SF-36 Physical component score, and SF-36 Mental component score at every interval (all P > .05). Instead of contrast agent injections that have been used for accurate nerve root identification during Selective Nerve Root Block, the method of merely checking if the needle-induced pain under fluoroscopic imaging is consistent with the LLRP that the patient predominantly experiences shows the same effect in the patient's pain control and functional outcome.

Review Case Reports
Acute respiratory distress syndrome associated with macrophage activation syndrome in systemic lupus erythematosus: A case report and literature review.
Previous treatment for macrophage activation syndrome (MAS) includes high-dose intravenous methylprednisolone along with intravenous immunoglobulin G. If MAS worsened, second-line therapy consisted of anakinra; if the disease remained refractory, third-line therapy with etoposide was considered. In addition, cyclosporine A plays a role in early MAS and in preventing recurrence. Some studies have reported the use of cytokine-targeting agents other than anakinra, such as canakinumab, tocilizumab, abatacept, and tofacitinib. ⋯ Early diagnosis of MAS and dexamethasone treatment for MAS with ARDS appear to be crucial for these patients.
