RESUMO

The green synthesis of zinc oxide nanoparticles (ZnO NPs) using plants has grown in significance in recent years. ZnO NPs were synthesized in this work via a chemical precipitation method with Jasminum sambac (JS) leaf extract serving as a capping agent. These NPs were characterized using UV-vis spectroscopy, FT-IR, XRD, SEM, TEM, TGA, and DTA. The results from UV-vis and FT-IR confirmed the band gap energies (3.37 eV and 3.50 eV) and the presence of the following functional groups: CN, OH, C=O, and NH. A spherical structure and an average grain size of 26 nm were confirmed via XRD. The size and surface morphology of the ZnO NPs were confirmed through the use of SEM analysis. According to the TEM images, the ZnO NPs had an average mean size of 26 nm and were spherical in shape. The TGA curve indicated that the weight loss starts at 100 °C, rising to 900 °C, as a result of the evaporation of water molecules. An exothermic peak was seen during the DTA analysis at 480 °C. Effective antibacterial activity was found at 7.32 ± 0.44 mm in Gram-positive bacteria (S. aureus) and at 15.54 ± 0.031 mm in Gram-negative (E. coli) bacteria against the ZnO NPs. Antispasmodic activity: the 0.3 mL/mL sample solution demonstrated significant reductions in stimulant effects induced by histamine (at a concentration of 1 µg/mL) by (78.19%), acetylcholine (at a concentration of 1 µM) by (67.57%), and nicotine (at a concentration of 2 µg/mL) by (84.35%). The antipyretic activity was identified using the specific Shodhan vidhi method, and their anti-inflammatory properties were effectively evaluated with a denaturation test. A 0.3 mL/mL sample solution demonstrated significant reductions in stimulant effects induced by histamine (at a concentration of 1 µg/mL) by 78.19%, acetylcholine (at a concentration of 1 µM) by 67.57%, and nicotine (at a concentration of 2 µg/mL) by 84.35%. These results underscore the sample solution's potential as an effective therapeutic agent, showcasing its notable antispasmodic activity. Among the administered doses, the 150 mg/kg sample dose exhibited the most potent antipyretic effects. The anti-inflammatory activity of the synthesized NPs showed a remarkable inhibition percentage of (97.14 ± 0.005) at higher concentrations (250 µg/mL). Furthermore, a cytotoxic effect was noted when the biologically synthesized ZnO NPs were introduced to treated cells.

RESUMO

Fever is a serious condition that can lead to various consequences ranging from prolonged illness to death. Tetrastigma hemsleyanum Diels et Gilg (T. hemsleyanum) has been used for centuries to treat fever, but the specific chemicals responsible for its antipyretic effects are not well understood. This study aimed to isolate and identify the chemicals with antipyretic bioactivity in T. hemsleyanum extracts and to provide an explanation for the use of T. hemsleyanum as a Chinese herbal medicine for fever treatment. Our results demonstrate that kaempferol 3-rutinoside (K3OR) could be successfully isolated and purified from the roots of T. hemsleyanum. Furthermore, K3OR exhibited a significant reduction in rectal temperature in a mouse model of fever. Notably, a 4 µM concentration of K3OR showed more effective antipyretic effects than ibuprofen and acetaminophen. To explore the underlying mechanism, we conducted an RNA sequencing analysis, which revealed that PXN may act as a key regulator in the fever process induced by lipopolysaccharide (LPS). In the mouse model of fever, K3OR significantly promoted the secretion of IL-6 and TNF-α during the early stage in the LPS-treated group. However, during the middle to late stages, K3OR facilitated the elimination of IL-6 and TNF-α in the LPS-treated group. Overall, our study successfully identified the chemicals responsible for the antipyretic bioactivity in T. hemsleyanum extracts, and it answered the question as to why T. hemsleyanum is used as a traditional Chinese herbal medicine for treating fever. These findings contribute to a better understanding of the therapeutic potential of T. hemsleyanum in managing fever, and they provide a basis for further research and development in this field.

RESUMO

BACKGROUND: Despite eradication efforts, ~135,000 African children sustained brain injuries as a result of central nervous system (CNS) malaria in 2021. Newer antimalarial medications rapidly clear peripheral parasitemia and improve survival, but mortality remains high with no associated decline in post-malaria neurologic injury. A randomized controlled trial of aggressive antipyretic therapy with acetaminophen and ibuprofen (Fever RCT) for malarial fevers being conducted in Malawi and Zambia began enrollment in 2019. We propose to use neuroimaging in the context of the RCT to further evaluate neuroprotective effects of aggressive antipyretic therapy. METHODS: This observational magnetic resonance imaging (MRI) ancillary study will obtain neuroimaging and neurodevelopmental and behavioral outcomes in children previously enrolled in the Fever RCT at 1- and 12-months post discharge. Analysis will compare the odds of any brain injury between the aggressive antipyretic therapy and usual care groups based upon MRI structural abnormalities. For children unable to undergo imaging without deep sedation, neurodevelopmental and behavioral outcomes will be used to identify brain injury. DISCUSSION: Neuroimaging is a well-established, valid proxy for neurological outcomes after brain injury in pediatric CNS malaria. This MRI ancillary study will add value to the Fever RCT by determining if treatment with aggressive antipyretic therapy is neuroprotective in CNS malaria. It may also help elucidate the underlying mechanism(s) of neuroprotection and expand upon FEVER RCT safety assessments.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: The desiccative ripe fruits of Gardenia (Gardenia jasminoides Ellis) (called Zhizi in China) are known with cold character and the effects of reducing fire except vexed, clearing away heat evil, and cooling blood and eliminating stasis. Zhizi is often clinical formulated to treat various types of fever. Fever is a sign of inflammation and, geniposide from Zhizi has been proved with anti-inflammatory in various inflammatory models. AIM OF STUDY: The aim of this study was to investigate the antipyretic role of geniposide with three classical inflammatory fever models and explore the underlying mechanisms. MATERIALS AND METHODS: Water extract (WE), high polar part (HP), iridoid glycoside part (IG), and gardenia yellow pigment part (GYP) from Gardeniae Fructus (GF) were obtained from Zhizi. The antipyretic activities of these composes were tested with dry yeast induced fever rats. Geniposide was further purified from IG and the antipyretic activity was evaluated by gavage, intraperitoneal injection, and caudal intravenous injection to rats of fever induced by dry yeast, lipopolysaccharide (LPS), and 2, 4-dinitrophenol (DNP) in rats. Then, the mechanism of geniposide by intragastric administration was studied. The contents of thermoregulatory mediators and inflammatory factors relating to TLR4/NF-κB pathway in serum were determined by ELISA and Western blot, and the pathological changes of the hypothalamus were observed by HE staining. RESULTS: The temperature was decreased by geniposide in the three fever model rats. Geniposide can not only inhibit the increase of inflammatory factors in serum but also protect the hypothalamus from fever pathological damage in the three fever models. Western blot showed that geniposide could inhibit the TLR4/NF-κB pathway. CONCLUSION: Geniposide exerts antipyretic effect in febrile rats through modulating the TLR4/NF-κB signaling pathway.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: "Snow-white waterlily" (Nymphaea candida) dried flower possesses various efficacy in Uighur medicine such as reducing fever and nourishing the liver, anti-inflammatory and cough relieving, moistening the throat and quenching thirst. AIM OF THE STUDY: Polyphenols are characteristic component of N. candida as well as its quality markers, and the purpose of this study was to conduct investigations into anti-inflammatory, antitussive, antipyretic, and analgesic activities of the polyphenol-enriched fraction from N. candida (NCTP) in order to validate the traditional efficacy of this plant. MATERIALS AND METHODS: The polyphenols in NCTP were analyzed by HPLC, and an acute oral toxicity study was conducted for NCTP. The anti-inflammatory activities of NCTP were evaluated using xylene induced ear edema, capillary permeability, cotton pellet granuloma, and carrageenan-induced rat paw edema, of which multiple biochemical indices were measured in carrageenan-induced rat paw edema such as prostaglandin E2 (PGE2), cyclooxygenase-2 (COX-2),5-lipoxygenase (5-LOX), interleukin-6 (IL-6), interleukin-1ß (IL-1ß), tumor necrosis factor-α (TNF-α), malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione (GSH) activities; the analgesic activities were investigated using acetic acid writhing, hot plate test, and formalin test; the anti-tussive and antipyretic effects were tested by ammonia induced cough in mice and yeast-induced fever respectively. RESULTS: NCTP with LD50 of 5222 mg/kg was low toxicity and safety. NCTP (200 mg/kg) could significantly reduce ear swelling and capillary permeability by 30.63% and 31.37%, respectively. NCTP revealed 15.76% inhibiting activities in cotton pellet granuloma in mice at a dosage of 200 mg/kg. Furthermore, NCTP (50, 100, and 200 mg/kg) substantially decreased carrageenin-induced paw edema in rats between 1 and 5 h, and NCTP could decrease PGE2, 5-LOX, COX-2 levels as well as IL-6, IL-1ß, TNF-α activities compared with the control group; NCTP could decrease MDA contents in carrageenin-induced rise, and increase SOD and GSH activities. Furthermore, the dose-dependent inhibition effect of NCTP on pain was revealed in the hot plate experiment. In addition to reducing the amount of writhes brought on by acetic acid, NCTP (50, 100, and 200 mg/kg) significantly inhibited pain latency against both stages of the formalin test. Moreover, NCTP (50, 100, 200 mg/kg) showed the better antitussive activities in mice in a dose-dependent manner. In the yeast-induced pyrexia test, dosages of 50, 100, and 200 mg/kg resulted in a statistically significant drop in rectal temperature. CONCLUSION: The experimental results proved the analgesic, anti-inflammatory, anti-tussive and antipyretic activities of the polyphenol-enriched fraction from N. candida, and supported the traditional use of this plant as well.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Tetrastigma hemsleyanum Diels et Gilg, is one of the perennial evergreen plants with grass vine, which has obvious curative effect on severe infectious diseases. Although Tetrastigma hemleyanum has long been recognized for its capacity of antipyretic and antitoxic, its specific mechanism is unknown. AIM OF THE STUDY: To evaluate the antipyretic effect of Tetrastigma hemleyanum polysaccharide (THP) on mice with dry yeast-induced fever, and to explore its specific antipyretic mechanism. METHODS: In this study, THP was administered by aerosol in febrile mice. The rectal temperatures of treated animals were monitored at different time points. Histopathological evaluation and various inflammatory indexes were used to assess inflammatory damage. The concentration variations of the central neurotransmitter, endocrine system, substance and energy metabolism indicators were measured to explore the physiological mechanism. Quantitative real-time PCR, Western bolt and Immunohistochemistry were performed to identify the correlation between antipyretic and TLR4/NF-κB signaling pathway. RESULTS: THP reduced the body temperature of febrile mice induced by dry yeast, as well as the levels of thermogenic cytokines and downregulated the contents of thermoregulatory mediators. THP alleviated the pathological damage of liver and hypothalamus caused by fever. In addition, THP decreased the secretion of thyroid hormone, substance and energy metabolism related indicators. Furthermore, THP significantly suppressed TLR4/NF-κB signaling pathway-related indicators. CONCLUSIONS: In conclusion, our results suggest that inhaled THP exerts antipyretic effect by mediating the thermoregulatory mediator, decreasing the content of pyrogenic factors to lower the body temperature, and eventually restoring the high metabolic level in the body to normal via inhibiting TLR4/NF-κB signaling pathway. The study provides a reasonable pharmacodynamic basis for the treatment of polysaccharide in febrile-related diseases.

RESUMO

Acetaminophen is a widely used antipyretic and analgesic drug, and its overdose is the leading cause of drug-induced acute liver failure. This study aimed to investigate the effect and mechanism of Lacticaseibacillus casei Shirota (LcS), an extensively used and highly studied probiotic, on acetaminophen-induced acute liver injury. C57BL/6 mice were gavaged with LcS suspension or saline once daily for 7 days before acute liver injury was induced via intraperitoneal injection of 300 mg/kg acetaminophen. The results showed that LcS significantly decreased acetaminophen-induced liver and ileum injury, as demonstrated by reductions in the increases in aspartate aminotransferase, total bile acids, total bilirubin, indirect bilirubin, and hepatic cell necrosis. Moreover, LcS alleviated acetaminophen-induced intestinal mucosal permeability, decreased serum IL-1α and lipopolysaccharide levels, and elevated serum eosinophil chemokine (eotaxin) and hepatic glutathione levels. Furthermore, analysis of the gut microbiota and metabolome showed that LcS reduced the acetaminophen-enriched levels of Cyanobacteria, Oxyphotobacteria, long-chain fatty acids, cholesterol, and sugars in the gut. Additionally, the transcriptomic and proteomic results showed that LcS mitigated the decrease in metabolic and immune pathways as well as glutathione formation during acetaminophen-induced acute liver injury. This is the first study showing that pretreatment with LcS alleviates acetaminophen-enriched acute liver injury, and it provides a reference for the application of LcS.IMPORTANCEAcetaminophen is the most frequently used antipyretic analgesic worldwide. As a result, overdoses easily occur and lead to drug-induced acute liver injury, which quickly progresses to liver failure with a mortality of 60%-80% if not corrected in time. The current emergency treatment for overused acetaminophen needs to be administered within 8 hours to avoid liver injury or even liver failure. Therefore, developing preventive strategies for liver injury during planned acetaminophen medication is particularly important, preferably nonpharmacological methods. Lacticaseibacillus casei Shirota (LcS) is a famous probiotic that has been used for many years. Our study found that LcS significantly alleviated acetaminophen-induced acute liver injury, especially acetaminophen-induced liver injury toward fulminant hepatic failure. Here, we elucidated the function and potential mechanisms of LcS in alleviating acetaminophen-induced acute liver injury, hoping it will provide preventive strategies to people during acetaminophen treatment.

RESUMO

INTRODUCTION: Hyperpyrexia, algesia and inflammation are pathological disorders which are treated with synthetic as well as herbal medications. AIMS: The basic aim of the present study is to evaluate the ethnopharmacological activities of phytoconstituents that are present in C. colocynthis (fruit extract) by using in vivo and in silico studies. METHODS: Thirty-six albino rats were used in our studies with an average weight between 150-170 g. Anti-inflammatory activity was investigated using carrageenan (an extract from a red seaweed) that induced edema in albino rat paws. However, in antipyretic and analgesic activity studies, yeast and acetic acid were used to cause pyrexia or algesia, respectively. Different doses of acetone fruit extract were used to treat inflammation, pyrexia and algesia. RESULTS: Our results showed that the maximum percentage inhibition of acetonic fruit extract in anti-inflammatory and analgesic activities was observed at 70% and 100%, respectively, with 400 mg/kg doses, and in pyretic activity the maximum inhibitory percentage was 86% with a 100 mg/kg dose. In in silico analysis, we have shown that bioactive compounds (α-spinasterol, ascorbic acid and chlorogenic acid) found in fruit extract have outstanding inhibition properties that involves proteins PTGS2, TLR2 and TRPV4. C. colocynthis fruit extract shows results that are statistically significant (p < 0.005) and comparable to a reference drug. Acetonic fruit extract of C. colocynthis can be used as a natural and safe remedy with no side effects. CONCLUSION: Both in vivo and in silico studies on chlorogenic acid, ascorbic acid and α-spinasterol have shown that these are inhibitory compounds that can be used for boosting the immune response.

RESUMO

OBJECTIVE: There is conflicting evidence around prescription practices in the management of malnutrition; the study objective was to explore medication classifications prescribed and their relationship between time-to-recovery and specific demographic characteristics among children with malnutrition in Guatemala. DESIGN: Descriptive correlational study of data obtained in a retrospective record review. SAMPLE: Children aged 0-5 years with malnutrition treated in a Guatemalan Nutrition Rehabilitation Center between 2019 and 2020 (N = 155). MEASURES: Variables assessed were medication classification of prescribed medications, age, gender, time-to-recovery, malnutrition severity, and COVID cohort. RESULTS: The most frequently used medication classifications were vitamins (95%), respiratory (75%), antipyretic (68%), antibiotic (61%), and gastrointestinal agents (54%). Antibiotic, respiratory, corticosteroid, antipyretic, and gastrointestinal agents were prescribed significantly more in cases with a time-to-recovery of 6 weeks or greater. CONCLUSIONS: Medication classifications prescribed most often were related to common comorbidities of malnutrition and illnesses affecting children in Guatemala, such as respiratory and diarrheal diseases. The medication used in cases with a time-to-recovery of ≥6 weeks suggest these cases may have had more comorbidities, which could explain the longer recovery times. Caution is suggested in routine prophylactic antibiotic use in public health settings, given the lack of association with improved recovery times, the potential for antibiotic drug resistance, and the negative effects on renal function among children.

RESUMO

There are few reports on the association between antipyretic use and antibody titers in adolescents and young adults following SARS-CoV-2 vaccination. Multivariable linear regression analyses were performed to examine the association between antipyretic use and antibody titers. The use of antipyretics was not associated with antibody titers (ß coefficient [95% CI] = -0.107 [-0.438 to 0.224]).

RESUMO

OBJECTIVES: In Unani medicine, a comprehensive treatment plan has been delineated to deal with febrile illnesses using herbal drugs along with modified dietetics, which stands as a promising area of research. The present study was aimed at evaluating the antipyretic activity of the HAE of Artemisia absinthium L. whole plant as a standalone and as an adjuvant with barley water in an animal model of pyrexia to validate the age-old Unani principle of the treatment. METHODS: The pyrexia was induced in all the groups except the plain control using Brewer's yeast. Group II did not receive any treatment, while group III received crocin, group IV received HAE of A. absinthium, group V administered Ma al-Sha'ir, and group VI was treated with the HAE of A. absinthium along with Ma al-Sha'ir by oral route. The rectal temperature of each rat was recorded at '0' h, 30 min, 60 min, and 180 min. RESULTS: The mean rectal temperature of group III went down from 101.82±0.20 °F to 100.4±0.57 °F over the period of (0-180) minutes, whereas the mean temperature in group IV went down from 102.45±0.60 °F to 100.14±0.57 °F. The mean rectal temperature of group V decreased from 100.62±0.11 °F to 99.55±0.51 °F, while the mean rectal temperature of group VI went down from 101.95±0.1 °F to 97.7±0.11 °F. CONCLUSIONS: It is concluded that the HAE of A. absinthium L. as a standalone and along with Ma al Sha'ir showed excellent antipyretic activity as compared to the standard drug in an animal model.

RESUMO

CONTEXT: Zi Xue Powder (ZXP) is a traditional formula for the treatment of fever. However, the potential mechanism of action of ZXP remains unknown. OBJECTIVE: This study elucidates the antipyretic characteristics of ZXP and the mechanism by which ZXP alleviates fever. MATERIALS AND METHODS: The key targets and underlying fever-reducing mechanisms of ZXP were predicted using network pharmacology and molecular docking. The targets of ZXP anti-fever active ingredient were obtained by searching TCMSP, STITCH and HERB. Moreover, male Sprague-Dawley rats were randomly divided into four groups: control, lipopolysaccharide (LPS), ZXP (0.54, 1.08, 2.16 g/kg), and positive control (acetaminophen, 0.045 g/kg); the fever model was established by intraperitoneal LPS injection. After the fever model was established at 0.5 h, the rats were administered treatment by gavage, and the anal temperature changes of each group were observed over 10 h after treatment. After 10 h, ELISA and Western blot analysis were used to further investigate the mechanism of ZXP. RESULTS: Network pharmacology analysis showed that MAPK was a crucial pathway through which ZXP suppresses fever. The results showed that ZXP (2.16 g/kg) decreased PGE2, CRH, TNF-a, IL-6, and IL-1ß levels while increasing AVP level compared to the LPS group. Furthermore, the intervention of ZXP inhibited the activation of MAPK pathway in LPS-induced fever rats. CONCLUSIONS: This study provides new insights into the mechanism by which ZXP reduces fever and provides important information and new research ideas for the discovery of antipyretic compounds from traditional Chinese medicine.

RESUMO

Background: As China amends its "zero COVID" strategy, a sudden increase in the number of infections may overwhelm medical resources and its impact has not been quantified. Specific mitigation strategies are needed to minimize disruption to the healthcare system and to prepare for the next possible epidemic in advance. Method: We develop a stochastic compartmental model to project the burden on the medical system (that is, the number of fever clinic visits and admission beds) of China after adjustment to COVID-19 policy, which considers the epidemiological characteristics of the Omicron variant, age composition of the population, and vaccine effectiveness against infection and severe COVD-19. We also estimate the effect of four-dose vaccinations (heterologous and homologous), antipyretic drug supply, non-pharmacological interventions (NPIs), and triage treatment on mitigating the domestic infection peak. Result: As to the impact on the medical system, this epidemic is projected to result in 398.02 million fever clinic visits and 16.58 million hospitalizations, and the disruption period on the healthcare system is 18 and 30 days, respectively. Antipyretic drug supply and booster vaccination could reduce the burden on emergency visits and hospitalization, respectively, while neither of them could not reduce to the current capacity. The synergy of several different strategies suggests that increasing the heterologous booster vaccination rate for older adult to over 90% is a key measure to alleviate the bed burden for respiratory diseases on the basis of expanded healthcare resource allocation. Conclusion: The Omicron epidemic followed the adjustment to COVID-19 policy overloading many local health systems across the country at the end of 2022. The combined effect of vaccination, antipyretic drug supply, triage treatment, and PHSMs could prevent overwhelming medical resources.

RESUMO

OBJECTIVE: This study aimed to explore paediatric hospitalisation related to medication administration errors (MAEs) of non-opioid analgesics, antipyretics and antirheumatics in England and Wales. DESIGN: An ecological study. SETTING: A population-based study on hospitalised patients in England and Wales. Hospital admission data were extracted from the Hospital Episode Statistics database in England and the Patient Episode Database for Wales for the period between April 1999 and April 2020. Admissions cause was confirmed using the diagnostic codes T39.0-T39.9. PARTICIPANTS: Paediatric patients aged 15 years and below who were hospitalised at all National Health Service (NHS) trusts and any independent sector funded by NHS trusts. PRIMARY OUTCOME MEASURE: Hospitalisation rates related to MAEs of non-opioid analgesics, antipyretics and antirheumatics. RESULTS: The yearly number of admissions for MAEs associated with non-opioid analgesics, antipyretics and antirheumatics experienced a notable growth of 21.7% over the span of two decades, rising from 4574 cases in 1999 to 5568 cases in 2020. The observed increase demonstrates a significant upward trend in hospital admissions rate, with a 12.3% growth from 46.16 per 100 000 individuals in 1999 to 51.83 per 100 000 individuals in 2020 (95% CIs 44.83 to 47.50 and 50.47 to53.19, respectively, trend test, p<0.05). The therapeutic categories that exhibited the highest frequency of MAEs were '4-aminophenol derivatives' and 'other non-steroidal anti-inflammatory drugs', accounting for 79.3% and 16.0% of cases, respectively. It is worth noting that there was a significant increase of 28.9% in hospitalisations linked to MAEs specifically associated with '4-aminophenol derivatives.' CONCLUSION: The research revealed a notable rise in the overall yearly number of hospital admissions associated with MAEs within the paediatric population. This study emphasises the necessity for additional research aimed at mitigating the potential hazards associated with the ingestion of these medications, particularly within susceptible demographics, such as young children.

RESUMO

OBJECTIVE: To explore the correlation between prescribing rate of medications and hospital admissions related to medications administration errors in England and Wales during the time from 1999 to 2020. DESIGN: An ecological study. SETTING: A population-based study using hospital admission data that are publicly available in the UK. Data in this study were extracted from the Hospital Episode Statistics database in England and the Patient Episode Database in Wales from Wales. The Prescription Cost Analysis database was used to extract the prescription data. PARTICIPANTS: Patients who were hospitalised all National Health Service (NHS) trusts and any independent sector funded by NHS trusts. PRIMARY OUTCOME MEASURE: Hospitalisation rates related to medication administration errors and its associated prescriptions. RESULTS: The annual rate of hospital admissions related to medication administration errors increased by 32.0% (from 184.21 (95% CI 183.0 to 185.4) in 1999 to 243.18 (95% CI 241.9 to 244.4) in 2020 per 100 000 persons. The most common three indications of hospital admissions were T39 (non-opioid analgesics, antipyretics and antirheumatics), T43 (psychotropic drugs), T42 (antiepileptic, sedative-hypnotic and antiparkinsonism drugs). The age group 15-59 years had the highest number of hospital admissions (83.4%). Women contributed to 59.1% of the total number of hospital admissions. Admission rate among men increased by 16.7%. Among women, the admission rate increased by 44.6%. CONCLUSION: Admission rates due to medication administration errors increased markedly in the past decade. This increase was correlated with an increase in the prescription rate of several therapeutic classes. Patients taking non-opioid analgesics, antipyretics and antirheumatics, psychiatric medications, antiepileptic, sedative-hypnotic and antiparkinsonism drugs should have their recommended (and administered) doses closely monitored. They should be followed up on a regular basis to ensure that they are taking their medications as prescribed.

RESUMO

Antipyretic analgesics are used to manage and control symptoms occurring after vaccination, but may hamper immunogenicity or vaccine efficacy. We examined the association between prophylactic or therapeutic use of antipyretic analgesics and SARS-CoV-2 antibody titers for vaccine recipients. Data were obtained from 1,498 staff members of a medical and research institution in Tokyo, Japan, who had received the second dose of the BNT162b2 vaccine. We quantitatively measured anti-SARS-CoV-2 spike protein IgG titers in the participants three months after vaccination. The prophylactic and therapeutic use of antipyretic analgesics was ascertained via a questionnaire. A linear regression model was used to examine the association between antipyretic analgesic use and log-transformed anti-SARS-CoV-2 spike protein IgG titers. Based on model parameters, we estimated geometric mean titers (GMT) and the corresponding 95 % confidence intervals (CI). The results showed that IgG titers in vaccine recipients who used antipyretic analgesics therapeutically was higher than the titers in those who did not (geometric mean ratio [GMR] = 1.26, 95 % CI = 1.17-1.34) with GMTs being 6,147 (95 % CI = 5,833-6,460) and 4,895 (95 % CI = 4,676-5,115) for those who used antipyretic analgesics therapeutically and those who did not, respectively. The association was attenuated, but remained statistically significant after adjusting for symptoms (GMR = 1.14, 95 % CI = 1.06-1.23). We did not find any evidence of significant association in relation to the prophylactic use of antipyretic analgesics (GMR = 0.96, 95 % CI = 0.84-1.10), with GMTs being 5,245 (95 % CI = 4,577-5,913) and 5,452 (95 % CI = 5,258-5,645) for those who used antipyretic analgesics prophylactically and those who did not, respectively. In conclusion, we did not find any evidence of suppression of the humoral response after the second dose of SARS-CoV-2 vaccination by prophylactic or therapeutic use of antipyretic analgesics.

RESUMO

Aloe barbadensis is a stemless plant with a length of 60-100 cm with juicy leaves which is used for its remedial and healing properties in different suburbs of various countries. The present study was conducted to investigate the effect of A. barbadensis leaf extract (aqueous and ethanolic) in yeast induced pyrexia and acetic acid induced writhing in rat model to evaluate the antipyretic biomarkers and its phytochemical screening with computational analysis. For analgesic activity model 60 Albino rats (160-200 kg) were divided into four groups. Of the 4 groups, control consisted of 6 rats (Group I) treated with normal saline, standard comprised of 6 rats treated with drug diclofenac (Group I). Experimental groups consisted of 48 rats, treated with A. barbadensis ethanolic and aqueous leaf extracts at doses of 50 mg/kg, 100 mg/kg, 200 mg/kg, and 400 mg/kg (Group III. IV). For antipyretic activity group division was same as in analgesic activity. All groups were treated the same as in the analgesic activity except for the second group which was treated with paracetamol. In both antipyretic and analgesic activity at the dose of 400 mg/kg, group III showed significant inhibition. TNF-α and IL-6 showed significant antipyretic activity at a dose of 400 mg/kg. For molecular docking aloe emodin and cholestanol were used as ligand molecules to target proteins Tnf-α and IL-6. Acute oral toxicity study was performed. There was no mortality even at the dose of 2000 mg/kg. Quantitative and qualitative phytochemical screening was performed for the detection of various phytochemicals. Hence, A. barbadensis leaf extracts can be used in the form of medicine for the treatment of pain and fever.

RESUMO

The simultaneous monitoring of individual or multiple diseases can be achieved by selecting therapeutic medicines used to treat the primary symptoms of the condition as biomarkers in wastewater. This study proposes a novel approach to monitor the prevalence of COVID-19 and influenza A (H1N1) by selecting nine medicines to serve as biomarkers, including three antipyretics, three antivirals, and three cough suppressants. To verify our approach, wastewater samples were collected from seventeen urban and five rural wastewater treatment plants (WWTPs) in a Chinese city over a period of one year. The use of antipyretics increased notably during the COVID-19 pandemic, while the consumption of antivirals for influenza A (H1N1) rose in the post-COVID-19 pandemic period, indicating a minor spike in the occurrence of influenza A (H1N1) after the COVID-19 pandemic. Fever is a significant symptom of COVID-19 and can serve as a reliable indicator of disease prevalence. Our research found that the prevalence of COVID-19 in urban areas was significantly higher (at 78.5 %, 95 % CI: 73.4 % - 83.9 %) than in rural areas (with a prevalence of 48.1 %, 95 % CI: 42.4 % - 53.8 %). The prevalence of COVID-19 in urban areas in this study was consistent with the data reported by the Chinese center for Disease Control and Prevention (82.4 %). Continuous monitoring of WWTPs in urban areas with fluctuating populations and complex demographics can provide early disease warning. Our results demonstrate the feasibility of evaluating community disease prevalence by selecting major therapeutic medicines as biomarkers in wastewater.

RESUMO

Background: On January 8, 2023, a change in the control policy for COVID-19 was implemented in China, whereby patient self-management of fever typically entails the utilization of over-the-counter fever-reducing medications. Objective: This study aimed to investigate the knowledge, attitudes, and practices (KAP) toward over-the-counter (OTC) antipyretics among fever patients. Methods: This cross-sectional study was conducted between October 2022 and February 2023 at author's hospital in Wuhan, China, among fever patients on OTC antipyretics, using a self-administered questionnaire. Results: A total of 481 valid questionnaires were collected, with the age of 36.05 ± 12.10 years, including 240 (49.90%) males, and 209 (43.45%) collected before policy change. The knowledge, attitudes, precautions for medication administration and decision-making practices scores were 6.86 ± 3.30 (possible range: 0-12), 16.67 ± 2.46 (possible range: 7-35), 29.98 ± 5.41 (possible range: 7-35) and 27.87 ± 1.28 (possible range: 8-40), respectively. The multivariable logistic regression analysis showed that knowledge (OR = 0.83, 95%CI: 0.81-0.92, p < 0.001) was independently associated with positive attitude. Knowledge (OR = 1.41, 95%CI: 1.28-1.56, p < 0.001), attitude (OR = 0.87, 95%CI: 0.79-0.95, p = 0.004), suburban (OR = 0.45, 95%CI: 0.23-0.88, p = 0.019) were independently associated with proactive precautions for medication administration practices. Knowledge (OR = 1.14, 95%CI: 1.07-1.22, p < 0.001), attitude (OR = 0.90, 95%CI: 0.82-0.98, p = 0.018), responding after policy change, 2023 (OR = 1.70, 95%CI: 1.10-2.63, p = 0.016) were independently associated with proactive decision making practices. Conclusion: Fever patients had moderate knowledge, negative attitude, proactive precautions for medication administration practices, moderate decision-making practices. After the policy change, there was a significant increase in knowledge regarding medication administration precautions and decision-making.
