Herbal Medications Used to Treat Fever.
Hines, CB
The Nursing clinics of North America. 2021;(1):91-107
Abstract
Fever is a natural body defense and a common symptom of disease. Herbs have been used for thousands of years to treat fever. Many herbs have anti-inflammatory properties. Some are useful in reducing the release of cytokines and mediators of inflammation, whereas others work as natural aspirins to inhibit cyclooxygenase. In addition, herbs have known antipathogenic properties and can be effective in the treatment of infection from numerous microorganisms. Last, in traditional Chinese medicine, herbs are used to restore imbalances between the nonpathogenic and the pathogenic clearing interior heat and treating heat patterns in a variety of ways.

Abstract
OBJECTIVE We aimed to investigate the relationship between clinical characteristics, outcomes and the severity of severe acute respiratory syndrome coronavirus 2 pneumonia. METHODS We performed a systematic review and meta-analysis using PubMed, Embase, and Cochrane Library databases to assess the clinical characteristics and outcomes of confirmed COVID-19 cases and compared severe (ICU) and nonsevere (non-ICU) groups. RESULTS We included 12 cohort studies including 2,445 patients with COVID-19. Compared with nonsevere (non-ICU) patients, severe (ICU) disease was associated with a smoking history (P = .003) and comorbidities including chronic obstructive pulmonary disease (OR = 5.08, P < .001), diabetes (OR = 3.17, P < .001), hypertension (OR = 2.40, P < .001), coronary heart disease (OR = 2.66, P < .001), cerebrovascular diseases (OR = 2.68, P = .008), and malignancy (OR=2.21, P = .040). We found significant differences between the 2 groups for fever, dyspnea, decreased lymphocyte and platelet counts, and increased leukocyte count, C-creative protein, procalcitonin, lactose dehydrogenase, aspartate aminotransferase, alanine aminotransferase, creatinine kinase, and creatinine levels (P < .05). Significant differences were also observed for multiple treatments (P < .05). Patients in the severe (ICU) group were more likely to have complications and had a much higher mortality rate and lower discharge rate than those with nonsevere (non-ICU) disease (P < .05). CONCLUSIONS Investigation of clinical characteristics and outcomes of severe cases of COVID-19 will contribute to early prediction, accurate diagnosis, and treatment to improve the prognosis of patients with severe illness.

Neurocritical care and target immunotherapy for febrile infection-related epilepsy syndrome.
Sakuma, H, Horino, A, Kuki, I
Biomedical journal. 2020;(3):205-210
Abstract
Febrile infection-related epilepsy syndrome (FIRES) is an intractable neurological disease characterized by an unexplained refractory status epilepticus triggered by febrile infection. A Consensus definition of FIRES was proposed in 2018, and its clinical features and prognosis are gradually being clarified. However, the development of effective treatments has been hindered as the etiology of this rare disease is as yet unelucidated. The basic approach to the management of FIRES, like other forms of epilepsy, is based on the control of seizures, however seizures are extremely intractable and require intravenous administration of large doses of anticonvulsants, mainly barbiturates. This treatment strategy produces various complications including respiratory depression and drug hypersensitivity syndrome, which make it more difficult to control seizures. Consequently, it is crucial to predict these events and to formulate a planned treatment strategy. As well, it is important to grow out of conventional treatment strategies that rely on only anticonvulsants, and alternative therapies are gradually being developed. One such example is the adoption of a ketogenic diet which may lead to reduced convulsions as well as improve intellectual prognosis. Further, overproduction of inflammatory cytokines in the central nervous system has been shown to be strongly related to the pathology of FIRES which has led to attempts at immunomodulation therapy including anti-cytokine therapy.

Abstract
We conducted a prospective, multicenter, non-randomized observational study to assess the duration of fever and symptoms of influenza A/H1N1pdm09 and A/H3N2 infected children < 19 years old treated with either baloxavir or oseltamivir. Additionally, these symptoms were investigated in association with pre- and post-baloxavir treatment-emergent polymerase acidic unit (PA) variants as compared to non-substituted viruses. Following receipt of informed consent, baloxavir was administered to 102 influenza A patients, and oseltamivir to 52 patients during the 2018-2019 influenza season in Japan. The average age was higher in the baloxavir treatment group compared to the oseltamivir treatment group (10.6 ± 2.7 versus 6.9 ± 2.9 years old, p < 0.01). The duration of fever and symptoms in baloxavir-treated A/H1N1pdm09 and A/H3N2-infected children did not differ from those in oseltamivir-treated groups (median 22.0, 11.8, 23.0, and 21.0 h, and median 114.5, 121.0, 123.0, and 122.0 h, respectively). One (1.2%) of 83 A/H3N2 patients possessed a PA/I38T substituted virus prior to treatment. The frequency of PA variants in post-treatment samples obtained 2-11 days after beginning of baloxavir was 12.5% (4/32) for A/H1N1pdm09 and 14.1% (9/64) for A/H3N2 when the total number of cases was used as the denominator, however, were 57.1% (4/7) and 33.3% (9/27) when PCR-positive cases at the time of second sampling was used as the denominator. The most frequent PA substitution was I38T (9), with E23K (1), I38K (1), I38M (1), and PA/I38S (1) also observed. The duration of fever and overall symptoms did not differ significantly following baloxavir treatment in individuals with PA variant viruses, non-substituted virus, or in those that were PCR negative at the second sampling (median 20, 24 and 11 h, and median 121, 115 and 121 h, respectively). Rebound of viral RNA load was observed in 13.5% (2/13) of PA variants but it was not associated with recurrence of fever and symptoms. Hence, prolonged fever or symptoms were not observed in children treated with baloxavir following emergence of PA variants, however, further studies are needed to evaluate the clinical impact of PA variants.

Abstract
New-onset refractory status epilepticus (NORSE) and febrile infection-related epilepsy syndrome (FIRES) are relatively rare clinical presentations. They are characterized by de novo onset of refractory status epilepticus (RSE) without clearly identifiable acute or active cause (structural, toxic, or metabolic). We reviewed the literature using PubMed reports published between 2003 and 2019 and summarized the clinical, neurophysiological, imaging, and treatment findings. Focal motor seizures, which tend to evolve into status epilepticus, characterize the typical presentation. Disease course is biphasic: acute phase followed by chronic phase with refractory epilepsy and neurological impairment. Aetiology is unknown, but immune-inflammatory-mediated epileptic encephalopathy is suspected. Electroencephalograms show variety in discharges (sporadic or periodic, focal, generalized, or more frequently bilateral), sometimes with a multifocal pattern. About 70% of adult NORSE have abnormal magnetic resonance imaging (MRI); in paediatric series of FIRES, 61.2% of patients have a normal brain MRI at the beginning and only 18.5% during the chronic phase. No specific therapy for FIRES and NORSE currently exists; high doses of barbiturates and ketogenic diet can be used with some effectiveness. Recently, anakinra and tocilizumab, targeting interleukin pathways, have emerged as potential specific therapies. Mortality rate is around 12% in children and even higher in adults (16-27%).

Jang, JG, Hur, J, Choi, EY, Hong, KS, Lee, W, Ahn, JH
Journal of Korean medical science. 2020;(23):e209
Abstract
BACKGROUND Since its first detection in December 2019, coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 infection has spread rapidly around the world. Although there have been several studies investigating prognostic factors for severe COVID-19, there have been no such studies in Korea. METHODS We performed a retrospective observational study of 110 patients with confirmed COVID-19 hospitalized at a tertiary hospital in Daegu, Korea. Demographic, clinical, laboratory, and outcome data were collected and analyzed. Severe disease was defined as a composite outcome of acute respiratory distress syndrome, intensive care unit care, or death. RESULTS Diabetes mellitus (odds ratio [OR], 19.15; 95% confidence interval [CI], 1.90-193.42; P = 0.012), body temperature ≥ 37.8°C (OR, 10.91; 95% CI, 1.35-88.36; P = 0.025), peripheral oxygen saturation < 92% (OR, 33.31; 95% CI, 2.45-452.22; P = 0.008), and creatine kinase-MB (CK-MB) > 6.3 (OR, 56.84; 95% CI, 2.64-1,223.78, P = 0.010) at admission were associated with higher risk of severe COVID-19. The likelihood of development of severe COVID-19 increased with an increasing number of prognostic factors. CONCLUSION In conclusion, we found that diabetes mellitus, body temperature ≥ 37.8°C, peripheral oxygen saturation < 92%, and CK-MB > 6.3 are independent predictors of severe disease in hospitalized COVID-19 patients. Appropriate assessment of prognostic factors and close monitoring to provide the necessary interventions at the appropriate time in high-risk patients may reduce the case fatality rate of COVID-19.

Extinguishing Febrile Infection-Related Epilepsy Syndrome: Pipe Dream or Reality?
Payne, ET, Koh, S, Wirrell, EC
Seminars in neurology. 2020;(2):263-272
Abstract
Febrile infection-related epilepsy syndrome (FIRES) is a rare and devastating epileptic encephalopathy with historically abysmal neurocognitive outcomes, including a high incidence of mortality. It tends to affect children and young adults and is characterized by superrefractory status epilepticus following a recent febrile illness. Growing evidence suggests a heterogeneous etiology resulting in fulminant nonantibody-mediated neuroinflammation. For some children with FIRES, this aberrant neuroinflammation appears secondary to a functional deficiency in the endogenous interleukin-1 receptor antagonist. A precise etiology has not been identified in all FIRES patients, and current treatments are not always successful. Limited treatment evidence exists to guide choice, dosing, and duration of therapies. However, the ketogenic diet and certain targeted immunomodulatory treatments, including anakinra, appear safe and have been associated with relatively excellent clinical outcomes in some FIRES patients. Future prospective multicenter collaborative studies are needed to further delineate the FIRES heterogeneous disease pathophysiology and to determine the safety and efficacy of treatment strategies through a robust measurement of neurocognitive outcomes.

Abstract
OBJECTIVE To investigate the relationships between exercise and incidence of congenital anomalies and hyperthermia. DESIGN Systematic review with random-effects meta-analysis . DATA SOURCES Online databases were searched from inception up to 6 January 2017. STUDY ELIGIBILITY CRITERIA Studies of all designs were eligible (except case studies and reviews) if they were published in English, Spanish or French, and contained information on population (pregnant women without contraindication to exercise), intervention (subjective or objective measures of frequency, intensity, duration, volume or type of exercise, alone ["exercise-only"] or in combination with other intervention components [e.g., dietary; "exercise + co-intervention"]), comparator (no exercise or different frequency, intensity, duration, volume or type of exercise) and outcome (maternal temperature and fetal anomalies). RESULTS This systematic review and meta-analysis included 'very low' quality evidence from 14 studies (n=78 735) reporting on prenatal exercise and the odds of congenital anomalies, and 'very low' to 'low' quality evidence from 15 studies (n=447) reporting on maternal temperature response to prenatal exercise. Prenatal exercise did not increase the odds of congenital anomalies (OR 1.23, 95% CI 0.77 to 1.95, I2=0%). A small but significant increase in maternal temperature was observed from pre-exercise to both during and immediately after exercise (during: 0.26°C, 95% CI 0.12 to 0.40, I2=70%; following: 0.24°C, 95% CI 0.17 to 0.31, I2=47%). SUMMARY/CONCLUSIONS These data suggest that moderate-to-vigorous prenatal exercise does not induce hyperthermia or increase the odds of congenital anomalies. However, exercise responses were investigated in most studies after 12 weeks' gestation when the risk of de novo congenital anomalies is negligible.

Fuentes, D, Muñoz, NM, Guo, C, Polak, U, Minhaj, AA, Allen, WJ, Gustin, MC, Cressman, ENK
International journal of hyperthermia : the official journal of European Society for Hyperthermic Oncology, North American Hyperthermia Group. 2018;(1):559-567
Abstract
OBJECTIVE A molecular dynamics approach to understanding fundamental mechanisms of combined thermal and osmotic stress induced by thermochemical ablation (TCA) is presented. METHODS Structural models of fibronectin and fibronectin bound to its integrin receptor provide idealized models for the effects of thermal and osmotic stress in the extracellular matrix. Fibronectin binding to integrin is known to facilitate cell survival. The extracellular environment produced by TCA at the lesion boundary was modelled at 37 °C and 43 °C with added sodium chloride (NaCl) concentrations (0, 40, 80, 160, and 320 mM). Atomistic simulations of solvated proteins were performed using the GROMOS96 force field and TIP3P water model. Computational results were compared with the results of viability studies of human hepatocellular carcinoma (HCC) cell lines HepG2 and Hep3B under matching thermal and osmotic experimental conditions. RESULTS Cell viability was inversely correlated with hyperthermal and hyperosmotic stresses. Added NaCl concentrations were correlated with a root mean square fluctuation increase of the fibronectin arginylglycylaspartic acid (RGD) binding domain. Computed interaction coefficients demonstrate preferential hydration of the protein model and are correlated with salt-induced strengthening of hydrophobic interactions. Under the combined hyperthermal and hyperosmotic stress conditions (43 °C and 320 mM added NaCl), the free energy change required for fibronectin binding to integrin was less favorable than that for binding under control conditions (37 °C and 0 mM added NaCl). CONCLUSION Results quantify multiple measures of structural changes as a function of temperature increase and addition of NaCl to the solution. Correlations between cell viability and stability measures suggest that protein aggregates, non-functional proteins, and less favorable cell attachment conditions have a role in TCA-induced cell stress.

Abstract
OBJECTIVE To assess the efficacy and safety in 105 patients with seasonal Influenza in Beijing, the mixture prepared with Chinese medicines follows the treatment regimen of releasing exterior cold and clearing interior heat. METHODS Total 330 patients with seasonal influenza were enrolled and randomly and averagely divided into the Chinese herbal medicine, the western medicine and the Chinese patent medicine group. They were treated with Chinese medicine Oseltamivir Phosphate Capsules and the Scattering Wind and Resolving Toxins Capsules. The main efficacy indicators were the antifebrile onset time and recovery time of body temperature. The efficacy and safety of the mixture was scientifically evaluated. Comparisons of several variables were analyzed. RESULTS Median antifebrile onset time of the Chinese herbal medicine group was significantly shorter than the western medicine group (P < 0.05) and the Chinese patent medicine group (P < 0.05). The median antifebrile recovery time of the Chinese herbal medicine group was significantly shorter than the Chinese patent medicine group (P < 0.05). The groups evaluated by TCM symptom pattern effect, both the Chinese herbal medicine group and Western Medicine group were better than the Chinese patent medicine group (P < 0.05). The disappearance rate of main symptoms and some minor symptom patterns of the Chinese herbal medicine group were higher than the other 2 groups. CONCLUSION The mixture of releasing exterior cold and clearing interior heat could significantly shorten the fever time with safety.
