ABSTRACT
This study aimed to investigate the antioxidant and anti-inflammatory properties of quercetin on the cellular components of the Enteric Nervous System in the ileum of rats with arthritis. Rats were distributed into five groups: control (C), arthritic (AIA), arthritic treated with ibuprofen (AI), arthritic treated with quercetin (AQ) and arthritic treated with both ibuprofen and quercetin (AIQ). The ileum was processed for immunohistochemical techniques for HuC/D, calcitonin gene-related peptide, and vasoactive intestinal polypeptide. Measurements in histological sections, chemiluminescence assays, and total antioxidant capacity were also performed. Rheumatoid arthritis resulted in a decrease in neuronal density, yet neuroplasticity mechanisms were evident through observed changes in varicosities size and neuronal area compared to the control group. Reduced paw edema and neuroprotective effects were predominantly noted in both plexuses, as evidenced by the increased density preservation of HuC/D-IR neurons in the AIQ group. The increase of lipoperoxidation levels and paw edema volume in the AQ group was observed compared to the arthritic, whereas the AIQ group mainly showed similar results to those observed in the control. The enteropathy associated with arthritis proved to be significant in the field of gastroenterology, and the combination of quercetin and ibuprofen demonstrated promising anti-inflammatory and neuroprotective effects.

The challenges of the COVID-19 pandemic have highlighted an increasing clinical demand for safe and effective treatment options against an overzealous immune defence response, also known as the "cytokine storm". Andrographolide is a naturally derived bioactive compound with promising anti-inflammatory activity in many clinical studies. However, its cytokine-inhibiting activity, in direct comparison to commonly used nonsteroidal anti-inflammatory drugs (NSAIDs), has not been extensively investigated in existing literature. The anti-inflammatory activities of andrographolide and common NSAIDs, such as diclofenac, aspirin, paracetamol and ibuprofen were measured on lipopolysaccharide (LPS) and interferon-γ induced RAW264.7 cells. The levels of PGE2, nitric oxide (NO), TNF-α & LPS-induced release of pro-inflammatory cytokines on differentiated human macrophage THP-1 cells were measured against increasing concentrations of andrographolide and aforementioned NSAIDs. The associated mechanistic pathway was examined on NFκB using flow cytometry on the human endothelial-leukocyte adhesion molecule (ELAM9) (E-selectin) transfected RAW264.7 cells with green fluorescent protein (GFP). Andrographolide exhibited broad and potent anti-inflammatory and cytokine-inhibiting activity in both cell lines by inhibiting the release of IL-6, TNF-α and IFN-γ, which are known to play a key role in the etiology of cytokine storm and the pathogenesis of inflammation. In comparison, the tested NSAIDs demonstrated weak or no activity against proinflammatory mediators except for PGE2, where the activity of andrographolide (IC50 = 8.8 µM, 95% CI = 7.4 to 10.4 µM) was comparable to that of paracetamol (IC50 = 7.73 µM, 95% CI = 6.14 to 9.73 µM). The anti-inflammatory action of andrographolide was associated with its potent downregulation of NFκB. The wide-spectrum anti-inflammatory activity of andrographolide demonstrates its therapeutic potential against cytokine storms as an alternative to NSAIDs.

OBJECTIVE: Emerging data indicate that acetaminophen may adversely affect lung health. We examined whether acetaminophen compared with cyclooxygenase (COX) inhibitor alone for patent ductus arteriosus (PDA) is associated with mortality or respiratory morbidity in extremely preterm infants. METHODS: This is a retrospective cohort study using data from the National Institute of Child Health and Human Development Neonatal Research Network. Infants were born at 22 to 28 weeks' gestation or weighing 401 to 1000 g between 2016 and 2020 and received acetaminophen, ibuprofen, and/or indomethacin for PDA closure. The primary outcome was death or grade 2 to 3 bronchopulmonary dysplasia (BPD) at 36 weeks' postmenstrual age. Secondary outcomes included predischarge mortality and respiratory morbidities. Risk ratios were adjusted for baseline and early postnatal factors. Additional exploratory analyses were adjusted for later postnatal covariates. RESULTS: Of 1921 infants, 627 (32.6%) received acetaminophen and 1294 (67.3%) received COX inhibitor only. Multidrug therapy (42.9% vs 4.7%) and surgical or catheter PDA closure (26.5% vs 19.9%) were more common among acetaminophen-exposed infants. Death or grade 2 to 3 BPD at 36 weeks' postmenstrual age was similar between infants treated with acetaminophen versus COX inhibitor only (57.1% vs 58.3%; adjusted relative risk [aRR] 0.96, 95% confidence interval [CI] 0.87-1.06). Acetaminophen was associated with increased risk of predischarge mortality (13.3% vs 10.0%) when adjusting for perinatal and early postnatal factors (aRR 1.42, 95% CI 1.02-1.93), but not in exploratory analyses that included later postnatal factors (aRR 1.28, 95% CI 0.91-1.82). CONCLUSIONS: Treatment with acetaminophen versus COX inhibitor alone for PDA was not associated with the composite outcome of death or BPD in extremely preterm infants. Our results support further evaluation of whether acetaminophen for PDA increases mortality.

RESEARCH QUESTION: Does ibuprofen, a non-steroidal anti-inflammatory drug (NSAID), delay ovulation? DESIGN: Two-stage, proof-of-concept, controlled study, assessing the percentage of non-ovulated follicles 42 h after HCG injection in patients taking ibuprofen. The intervention group consisted of women undergoing natural cycle IVF treatment taking ibuprofen 3â¯×â¯400 mg per day. The control group consisted of women undergoing timed sexual intercourse or intrauterine insemination. The proportion of patients with non-ovulated follicles in the ibuprofen group was first compared against a reference of 50% using a one-sample binomial test, and second against the proportion observed in the control group using an adjusted logistic regression. RESULTS: A total of 26 women were recruited in the ibuprofen intervention group. Twenty-five patients were recruited in the control group. The proportion of patients with delayed ovulation observed (22/26 [84.6%]; 95% CI 65.1% to 95.6%) was significantly higher than the reference of 50% (P < 0.001). In the control group, the proportion of patients with delayed ovulation was 20.0% ([5/25], 95% CI 6.8% to 40.7%). Compared with the ibuprofen group, a significantly increased probability of a delayed ovulation was found in the ibuprofen intervention group (adjusted OR 22.72, 95% CI 5.77 to 115; P < 0.001). Of the 22 women with delayed ovulation, oocytes were retrieved in 20 women (90.9%) and all oocytes were mature (metaphase II). CONCLUSIONS: Women trying to conceive should avoid non-selective NSAIDs around the time of ovulation. Ibuprofen or other NSAID can be used to delay ovulation for several hours in assisted reproductive technology and other infertility treatments if required.

PURPOSE: To compare compliance with the French national guidelines before and after the implementation (in 2018) of a new protocol on acute fracture pain management in the pediatric emergency department of a French university medical center. METHODS: We conducted a retrospective, before-after study in patients aged below 16 years presenting at the pediatric emergency department with a fracture. We compared pain management before (in 2017) and after (in 2019 and 2020) implementation of the new procedure. The primary endpoint was appropriate pain management, defined as (i) an appropriate initial assessment of pain, (ii) appropriate treatment with analgesic drugs (acetaminophen for mild pain, acetaminophen and ibuprofen for moderate pain, ibuprofen and morphine for severe pain) and (iii) reassessment of the pain intensity. RESULTS: 572 patients were included (mean age: 6.5 years; male: 60%). 190 in 2017 and 382 in 2019-2020. Pain management was appropriate for 40% of the patients in 2017 and 52% in 2019-2020 (p = 0.004). Pain was rated for 98% of patients in 2017 vs. 100% in 2019-2020 (p = 0.04). The frequency of appropriate treatment for mild pain and moderate pain increased significantly from 52 to 76% and from 0 to 44%, respectively. The administration of ibuprofen increased by 26% points (from 3 to 20 patients treated) and the administration of morphine increased by 29% points (from 1 to 17 patients treated). Pain reassessment rose significantly from 21 to 43%. Levels of compliance with the guidelines were similar in 2019 and 2020. Analgesia was significantly more effective in 2019-2020 than in 2017 (in 20% vs. 14% of the patients, respectively; p = 0.005). CONCLUSION: After the implementation of a new protocol for the management of acute fracture pain, we observed an increase in compliance with the guidelines. Although the use of ibuprofen and morphine rose significantly as did the frequency of pain reassessment, further improvements are required.

BACKGROUND AND OBJECTIVE: Although paracetamol (acetaminophen) combined with other analgesics can reduce pain intensity in some pain conditions, its effectiveness in managing low back pain and osteoarthritis is unclear. This systematic review investigated whether paracetamol combination therapy is more effective and safer than monotherapy or placebo in low back pain and osteoarthritis. METHODS: Online database searches were conducted for randomised trials that evaluated paracetamol combined with another analgesic compared to a placebo or the non-paracetamol ingredient in the combination (monotherapy) in low back pain and osteoarthritis. The primary outcome was a change in pain. Secondary outcomes were (serious) adverse events, changes in disability and quality of life. Follow-up was immediate (≤ 2 weeks), short (> 2 weeks but ≤ 3 months), intermediate (> 3 months but < 12 months) or long term (≥ 12 months). A random-effects meta-analysis was conducted. Risk of bias was assessed using the original Cochrane tool, and quality of evidence using Grading of Recommendations Assessment, Development and Evaluation (GRADE). RESULTS: Twenty-two studies were included. Pain was reduced with oral paracetamol plus a non-steroidal anti-inflammatory drug (NSAID) at immediate term in low back pain (paracetamol plus ibuprofen vs ibuprofen [mean difference (MD) - 6.2, 95% confidence interval (CI) -10.4 to -2.0, moderate evidence]) and in osteoarthritis (paracetamol plus aceclofenac vs aceclofenac [MD - 4.7, 95% CI - 8.3 to - 1.2, moderate certainty evidence] and paracetamol plus etodolac vs etodolac [MD - 15.1, 95% CI - 18.5 to - 11.8; moderate certainty evidence]). Paracetamol plus oral tramadol reduced pain compared with placebo at intermediate term for low back pain (MD - 11.7, 95% CI - 19.2 to - 4.3; very low certainty evidence) and osteoarthritis (MD - 6.8, 95% CI - 12.7 to -0.9; moderate certainty evidence). Disability scores improved in half the comparisons. Quality of life was infrequently measured. All paracetamol plus NSAID combinations did not increase the risk of adverse events compared to NSAID monotherapy. CONCLUSIONS: Low-to-moderate quality evidence supports the oral use of some paracetamol plus NSAID combinations for short-term pain relief with no increased risk of harm for low back pain and osteoarthritis compared to its non-paracetamol monotherapy comparator.

PURPOSE: This study aims to conduct a thorough analysis, both quantitative and qualitative, of bibliometric parameters related to preemptive analgesia (PA) in oral surgical procedures (OSP). METHODS: Research trends on PA in OSP using ibuprofen were reviewed through bibliometric analysis of 68 journal articles published from 1991 to 2022 in the Web of Science database. Bibliometric indicators were applied to analyze the journal article data, including the annual distribution of publications and literature growth, document types, citation indicators to measure qualitative research performance, and keyword mapping to identify research trends. The results were imported into RStudio, and the Bibliometrix package was used to prepare and analyze the metadata. RESULTS: The 68 included articles received a total of 900 citations, ranging from 1 source to 72 citations with some fluctuations. The papers on PA in OSP using ibuprofen had an average of 16.85 citations per paper. These publications were originated from 25 countries, with the highest contributions from Brazil (n = 17), the USA (n = 13), and Turkey (n = 8). The top five major contributing journals were the International Journal of Oral and Maxillofacial Surgery, Journal of Oral and Maxillofacial Surgery, Journal of Cranio-Maxillo-Facial Surgery, Journal of Periodontology, and Acta Odontologica Scandinavica, representing more than half of all selected papers. CONCLUSION: Papers focused on PA in OSP received numerous citations. The citation per article correlated with the number of publications at the affiliation, author, country, and journal levels. However, there is still a scarcity of studies in this field.

Importance: A third of children who survive malaria with neurological involvement (central nervous system [CNS] malaria) develop sequelae. A higher maximum temperature (Tmax) and seizures are risk factors for sequelae. Objective: To compare aggressive antipyretic therapy using scheduled acetaminophen and ibuprofen vs usual care with acetaminophen alone given only for a temperature of 38.5 °C or higher. Design, Setting, and Participants: This randomized clinical trial was conducted at inpatient pediatric services of 1 tertiary care and 1 district hospital in Zambia and a tertiary care center in Malawi. Included were children aged 2 to 11 years with CNS malaria (excluding those with creatinine >1.2 mg/dL), who were enrolled from 2019 to 2022. Data analysis took place from December 2022 to April 2023. Intervention: The aggressive antipyretic group received acetaminophen (30 mg/kg load, then 15 mg/kg) plus ibuprofen, 10 mg/kg, every 6 hours, regardless of clinical temperature for 72 hours. The usual care group received 15 mg/kg of acetaminophen as needed every 6 hours for a temperature of 38.5 °C or higher. Main Outcomes and Measures: The primary outcome variable was Tmax over 72 hours, the total duration of follow-up. Secondary outcomes included seizures and parasite clearance. Results: Five hundred fifty-three patients were screened, 226 (40.9%) were ineligible, and 57 (10.3%) declined. A total 256 participants (n = 128/group) had a mean (SD) age of 4.3 (2.1) years; 115 (45%) were female, and 141 (55%) were male. The aggressive antipyretic group had a lower Tmax, 38.6 vs 39.2 °C (difference, -0.62 °C; 95% CI, -0.82 to -0.42; P < .001) and lower odds of experiencing multiple or prolonged seizures, 10 (8%) vs 34 children (27%) in the usual care group (odds ratio [OR], 0.26; 95% CI, 0.12 to 0.56). No group difference in parasite clearance time was detected. Severe adverse events occurred in 40 children (15%), 25 (20%) in the usual care group and 15 (12%) in the aggressive antipyretic group, including 13 deaths (10 [8%] and 3 [2%], respectively). Increased creatinine resulted in study drug discontinuation in 8 children (6%) in the usual care group and 13 children (10%) in the aggressive antipyretic group (OR, 1.74; 95% CI, 0.63 to 5.07). Conclusions and Relevance: This study found that aggressive antipyretic therapy reduced mean Tmax to temperature levels comparable with the Tmax among children without neurological impairments in prior observational studies and improved acute seizure outcomes with no prolongation of parasitemia. Trial Registration: ClinicalTrials.gov Identifier: NCT03399318.

BACKGROUND: Idiopathic carotidynia, also known as transient perivascular inflammation of the carotid artery (TIPIC) syndrome, is a rare, self-limited, clinical-radiologic entity. Over the years, the diagnosis of carotidynia has been controversial, but recent pathologic, radiologic, clinical, and laboratory findings support an inflammatory etiology. CASE REPORT: A 61-year-old woman with a history of hypertension, left lower extremity liposarcoma, and right internal jugular port placement 2 weeks prior with initiation of chemotherapy presented to the emergency department with right neck pain and swelling of the lateral neck and lower face for the past 3 days. Computed tomography-neck with IV contrast revealed marked mural thickening of the right common carotid artery, which can be seen with carotidynia (Fay syndrome and TIPIC syndrome) and vasculitis. The patient had elevated inflammatory markers and was treated clinically for carotidynia with ibuprofen, evaluated by vascular surgery, and discharged home. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: The causes of acute neck pain are diverse, ranging from nonemergent to surgically emergent etiologies. As radiologists and emergency physicians, we believe TIPIC syndrome is a rare entity with important clinical impact deserving attention, as it is not typically included in medical training and is usually learned only through years of clinical experience and practice. TIPIC syndrome requires a unique combination of both clinical and radiologic findings to diagnose accurately and appropriately. It is important to be familiar with this diagnosis because treatment is focused on symptomatic relief without the need for invasive procedures. Our goal was to increase awareness of this uncommon diagnosis to improve patient care by preventing unnecessary invasive procedures and aid in timely and accurate diagnosis.

Systemic sclerosis (SSc) is a devastating autoimmune illness with a wide range of clinical symptoms, including vascular abnormalities, inflammation, and persistent and progressive fibrosis. The disease's complicated pathophysiology makes it difficult to develop effective therapies, necessitating research into novel therapeutic options. Molecular hybridization is a strategy that can be used to develop new drugs that act on two or multiple targets and represents an interesting option to be explored for the treatment of complex diseases. We aimed to evaluate the effects of a hybrid mutual prodrug of ibuprofen and acetaminophen (IBPA) in peripheral blood mononuclear cells (PBMC) isolated from SSc patients, and in an in vivo model of SSc induced in BALB/c mice by intradermal injections of hypochlorous acid (HOCl) for 6 weeks. The mice were treated at the same time with daily intraperitoneal injections of IBPA (40 mg/kg). Pulmonary and skin fibrosis as well as immune responses were evaluated. IBPA significantly decreased the release of cytokines in PBMC culture supernatants from SSc patients after stimulation with phytohemagglutinin-M (IL-2, IL-4, IL-6, IL-10, IL-13, IL-17A, TNF and IFN-γ).In HOCl-induced SSc, IBPA treatment prevented dermal and pulmonary fibrosis, in addition to reducing CD4 + T and B cells activation and reversing the M2 polarization of macrophages in spleen cells, and inhibiting IFN-γ secretion in splenocyte cultures. These results show the anti-inflammatory and antifibrotic effects of IBPA in SSc and highlight the therapeutic potential of this mutual prodrug, providing support for future studies.

OBJECTIVES: This study examined the impact of premedication with ibuprofen and ibuprofen-arginine and the influence of preoperative pain and anxiety on inferior alveolar nerve block (IANB) efficacy in cases of symptomatic irreversible pulpitis. MATERIALS AND METHODS: The study involved 150 SIP patients who were randomly assigned to receive ibuprofen (600 mg), ibuprofen-arginine (1,155 mg), or a placebo 30 min before IANB. Preoperative anxiety and pain levels were assessed using the Modified Dental Anxiety Scale and the Heft-Parker visual scale. IANB efficacy was determined by the absence of or mild pain during the procedure. Statistical analysis included chi-square, z-tests, Analysis of Variance, and Student's t tests. RESULTS: The ibuprofen and ibuprofen-arginine groups exhibited significantly higher IANB success rates (62% and 78%, respectively) compared to the placebo group (34%). However, no significant difference was observed between the ibuprofen and ibuprofen-arginine groups. Patients with successful IANB in the ibuprofen and ibuprofen-arginine groups displayed lower median anxiety scores (8) than those with failed blocks (15) and lower mean preoperative pain scores (118.3). CONCLUSION: In cases of symptomatic irreversible pulpitis the preemptive medication with ibuprofen-arginine effectively increased the efficacy of the inferior alveolar nerve block The inferior alveolar nerve block efficacy was influenced by preoperative anxiety levels and the intensity of pain. CLINICAL RELEVANCE: This research underscores the potential benefits of oral premedication with ibuprofen and ibuprofen-arginine in improving anesthesia outcomes in cases of symptomatic irreversible pulpitis.

BACKGROUND: Most methodologically rigorous, ED-based, comparative effectiveness analgesic studies completed in the last two decades failed to find a clinically important difference between the comparators. We believe that many of these comparative effectiveness studies were biased towards the null hypothesis because some ED patients with intense pain will respond to relatively mild interventions. We hypothesized that including a run-in period would alter the results of an acute pain RCT. METHODS: We conducted a sequential, multiple-assignment, randomized study. Adults with acute moderate/severe musculoskeletal pain were randomized (3:1 ratio) to run-in period or no run-in. We administered 650 mg acetaminophen to run-in participants. Those run-in patients who reported insufficient relief one-hour later were randomized (1:1 ratio) to ibuprofen 800mg PO or ketorolac 20mg PO as were all participants randomized to no run-in. The primary outcome was achieving a clinically important improvement, defined as improvement ≥1.3 on a 0-10 scale. We built a logistic regression model including run-in/no run-in, ketorolac/ibuprofen, age and sex. RESULTS: Of 307 participants who received acetaminophen, 100 (32.6%) reported inadequate relief and were randomized to an NSAID. Of the 100 patients randomized to no run-in, 84/100 (84%) achieved the primary outcome versus 246/287 (86%) run-in participants (95% CI for difference = 2%:-7,10%). Among run-in participants who received an NSAID, 82/99(83%) achieved the primary outcome versus 84/100(84%) no run-in participants (p = 0.82). Among all ibuprofen participants, 44/49(90%) randomized to run-in and 42/50(84%) randomized to no run-in achieved the primary outcome. Among all ketorolac participants, 38/50(76%) randomized to run-in and 42/50 (84%) randomized to no run-in achieved the primary outcome. We observed the following results in a multivariable analysis: OR for ketorolac versus ibuprofen:0.60 (95% CI: 0.28, 1.28); OR for run-in versus no run-in:0.91(95% CI: 0.43, 1.93). CONCLUSIONS: Among patients with acute musculoskeletal pain, using an acetaminophen first strategy did not alter pain outcomes.

OBJECTIVES: Multimodal pain management is one component in enhanced recovery after surgery protocol. Here we evaluate the efficacy of tramadol-paracetamol in acute postoperative pain and pain outcome at 12 months after spine surgery in randomized, double-blind, placebo-controlled trial. METHODS: We randomized 120 patients undergoing spine surgery to receive, for add-on pain management, two tramadol-paracetamol 37.5 mg/325 mg (n = 61) or placebo tablets (n = 59) twice a day for 5 postoperative days. In the hospital, multimodal pain management consisted of dexketoprofen and oxycodone. After discharge, patients were prescribed ibuprofen 200 mg, maximum 1,200 mg/day. Pain, analgesic use, and satisfaction with pain medication were followed up with the Brief Pain Inventory questionnaire before surgery and at 1 and 52 weeks after surgery. The primary outcome was patients' satisfaction with pain medication 1 week after surgery. RESULTS: At 1 week after surgery, patients' satisfaction with pain medication was similarly high in the two groups, 75% [interquartile range, 30%] in the placebo group and 70% [40%] in the tramadol-paracetamol group (p = 0.949) on a scale: 0% = not satisfied, 100% = totally satisfied. At 1 week, ibuprofen dose was lower in the placebo group 200 mg [1,000] compared to the tramadol-paracetamol group, 800 mg [1,600] (p = 0.016). There was no difference in the need for rescue oxycodone. Patients in the tramadol-paracetamol group had more adverse events associated with analgesics during the first postoperative week (relative risk = 1.8, 95% confidence interval, 1.2-2.6). CONCLUSION: Add-on pain treatment with tramadol-paracetamol did not enhance patients' satisfaction with early pain management after back surgery.

OBJECTIVES: The goal was to evaluate neonatal outcomes based on treatment strategies and time points for haemodynamically significant patent ductus arteriosus (hsPDA) in very-low-birth-weight preterm infants, with a particular focus on surgical closure. METHODS: This retrospective study included very-low-birth-weight infants born between 2014 and 2021 who received active treatment for hsPDA. Neonatal outcomes were compared between (i) primary surgical closure versus primary ibuprofen; (ii) early (<14th post-natal day) versus late primary surgical closure (≥14th post-natal day); and (iii) primary versus secondary surgical closure after ibuprofen failure. Further analysis using 1:1 propensity score matching was performed. Logistic regression was conducted to analyse the risk factors for post-ligation cardiac syndrome (PLCS) and/or acute kidney injury (AKI). RESULTS: A total of 145 infants with hsPDA underwent active treatment for closure. The in-hospital death rate and the incidence of severe bronchopulmonary dysplasia (BPD) were similar between the primary surgical closure group and the primary ibuprofen group in a 1:1 matched analysis. Severe BPD was significantly higher in the late surgical closure group than in the early primary surgical closure group with 1:1 propensity score matching (72.7% vs 40.9%, P=0.033). The secondary surgical closure group showed the mildest clinical condition; however, the probability of PLCS/AKI was highest (38.6%) compared to the early (15.2%) or the late primary surgical group (28.1%, P<0.001), especially in extremely premature infants (gestational age < 28 weeks). CONCLUSIONS: Surgical patent ductus arteriosus closure is not inferior to pharmacologic treatment. Considering the harmful effect of a prolonged patent ductus arteriosus shunt exposure, a timely decision and timely efforts should be made to minimize the risk of severe BPD and PLCS/AKI after surgical closure.

OBJECTIVE: Tension-type headache is the most common type of primary headache and results in a huge socioeconomic burden. This network meta-analysis (NMA) aimed to compare the efficacy and safety of simple analgesics for the treatment of episodic tension-type headache (ETTH) in adults. METHODS: We searched the Cochrane Library, PubMed, Web of Science, Embase, Chinese BioMedical Literature database and International Clinical Trials Registry Platform databases for eligible randomized clinical trials reporting the efficacy and/or safety of simple analgesics. A Bayesian NMA was performed to compare relative efficacy and safety. The surface under the cumulative ranking curve (SUCRA) was calculated to rank interventions. PROSPERO registration number: CRD42018090554. RESULTS: We highlighted six studies including 3507 patients. For the 2 h pain-free rate, the SUCRA ranking was ibuprofen > diclofenac-K > ketoprofen > acetaminophen > naproxen > placebo. All drugs except naproxen reported a higher 2 h pain-free rate than placebo, with a risk ratio (RR) of 2.86 (95% credible interval, CrI: 1.62-5.42) for ibuprofen and 2.61 (1.53-4.88) for diclofenac-K. For adverse events rate, the SUCRA ranking was: metamizol > diclofenac-K > ibuprofen > lumiracoxib > placebo > aspirin > acetaminophen > naproxen > ketoprofen. The adverse event rates of all analgesics were no higher than those of placebo, except for ketoprofen. Moreover, all drugs were superior to placebo in the global assessment of efficacy. In particular, the RR of lumiracoxib was 2.47 (1.57-4.57). Global heterogeneity I2 between the studies was low. CONCLUSIONS: Simple analgesics are considered more effective and safe as a placebo for ETTH in adults. Our results suggest that ibuprofen and diclofenac-K may be the two best treatment options for patients with ETTH from a comprehensive point of view (both high-quality evidence).
To our knowledge, this is the first network meta-analysis comparing the available data on adult patients with episodic tension-type headache (ETTH) treated with different simple analgesics recommended by the current guidelines.Ibuprofen (400 mg) and diclofenac-K (12.5 mg, 25 mg) are potentially the most effective and safe treatment options, supported by high-quality evidence.

OBJECTIVE: To investigate claims patterns for metamizole and other non-opioid analgesics in Switzerland. To characterise users of these non-opioid analgesics regarding sex, age, comedications and canton of residence. METHODS: We conducted a retrospective descriptive study using administrative claims data of outpatient prescribed non-opioid analgesics of the Swiss health insurance company Helsana between January 2014 and December 2019. First, we evaluated the number of claims and defined daily doses per year of metamizole, ibuprofen, diclofenac and paracetamol in adults aged 18 years or over. Second, we characterised new users of these non-opioid analgesics in terms of sex, age, claimed comedications and canton of residence. RESULTS: From 2014 to 2019, among the investigated non-opioid analgesics, metamizole showed the highest increase in claims (+9545 claims, +50%) and defined daily doses (+86,869 defined daily doses, +84%) per 100,000 adults. Metamizole users had the highest median age (62 years [IQR: 44-77]) compared to ibuprofen (47 years [IQR: 33-62]), diclofenac (57 years [IQR: 43-71]) and paracetamol (58 years [IQR: 39-75]) users. Metamizole users also more frequently claimed proton pump inhibitors, anticoagulants, platelet aggregation inhibitors and antihypertensive drugs than users of other non-opioid analgesics. While metamizole was most frequently claimed in German-speaking regions of Switzerland, ibuprofen and paracetamol were most frequently claimed in the French-speaking regions and diclofenac in German- and Italian-speaking regions. CONCLUSION: In Switzerland, metamizole was increasingly claimed between 2014 and 2019. Metamizole was most frequently claimed by older adults and patients with comedications suggestive of underlying conditions, which can be worsened or caused by use of nonsteroidal anti-inflammatory drugs. The lack of studies regarding the effectiveness and safety of metamizole in this population warrants further investigation.

OBJECTIVES: To investigate the risk factors for the failure of ibuprofen treatment in preterm infants with hemodynamically significant patent ductus arteriosus (hsPDA). METHODS: A retrospective collection of clinical data was conducted on preterm infants with a gestational age of <34 weeks who were diagnosed with hsPDA and treated at the Department of Neonatology, Maternal and Child Health Hospital of Hubei Province, Tongji Medical College, Huazhong University of Science and Technology, from January 2018 to June 2023. The subjects were divided into two groups based on the treatment approach: the ibuprofen group (95 cases) and the ibuprofen plus surgery group (44 cases). The risk factors for the failure of ibuprofen treatment in preterm infants with hsPDA were identified by binary logistic regression analysis. RESULTS: The binary logistic regression analysis revealed that an increased diameter of the ductus arteriosus, a resistance index (RI) value of the middle cerebral artery ≥0.80, and prolonged total invasive mechanical ventilation time were risk factors for the failure of ibuprofen treatment in preterm infants with hsPDA (P<0.05). Receiver operating characteristic curve analysis showed that a ductus arteriosus diameter >2.85 mm, a middle cerebral artery RI value ≥0.80, and a total invasive mechanical ventilation time >16 days had significant predictive value for the failure of ibuprofen treatment in preterm infants with hsPDA (P<0.05). The combined predictive value of these three factors was the highest, with an area under the curve of 0.843, a sensitivity of 86.5%, and a specificity of 75.0% (P<0.05). CONCLUSIONS: A ductus arteriosus diameter >2.85 mm, a middle cerebral artery RI value ≥0.80, and a total invasive mechanical ventilation time >16 days are risk factors for the failure of ibuprofen treatment in preterm infants with hsPDA, and they are of significant predictive value for the necessity of surgical treatment following the failure of ibuprofen treatment.
