Ibuprofen delays ovulation by several hours: prospective controlled study in natural cycles with HCG-triggered ovulation.

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 3 × 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.

Grisel's Syndrome After COVID-19 in a Pediatric Patient: A Case Report.

An eight-year-old female presenting with posterior neck pain and torticollis who had been diagnosed with coronavirus disease 2019 (COVID-19) three weeks earlier was radiographed and diagnosed with atlantoaxial rotatory fixation (AARF). Following treatment with non-steroidal anti-inflammatory drugs (NSAIDs), the posterior neck pain improved, and the torticollis was cured. Symptoms returned after two weeks, and computed tomography showed a 3.94 mm atlantodental interval and axis rotation. The patient was diagnosed with AARF relapse; symptoms resolved spontaneously prior to subsequent examination, and no further relapses were observed. This case highlights the need for clinicians to be aware that AARF may develop after COVID-19. Treatment options should be carefully considered.

Celecoxib-tramadol co-crystal in patients with moderate-to-severe pain following bunionectomy with osteotomy: Secondary analyses by baseline pain intensity and use of rescue medication of a phase 3, randomized, double-blind, factorial, active- and placebo-controlled trial.

BACKGROUND: In the randomized, phase 3, SUSA-301 trial, celecoxib-tramadol co-crystal (CTC) provided significantly greater analgesia compared with celecoxib, tramadol, or placebo in adults with acute, moderate-to-severe, postoperative pain. This post hoc, secondary analysis further evaluated the use of rescue medication and the incidence of treatment-emergent adverse events (TEAEs). METHODS: Patients (N = 637) were randomized 2:2:2:1 to receive oral CTC 200 mg twice daily (BID; n = 184), tramadol 50 mg four times daily (QID; n = 183), celecoxib 100 mg BID (n = 181), or placebo QID (n = 89). Post hoc analyses were conducted on the use of rescue medications up to 4 and 48 h post-study drug dose, stratified by baseline pain intensity (moderate/severe), and on the incidence of TEAEs, stratified by rescue medication use. RESULTS: A significantly lower proportion of patients received any rescue medication within 4 h post-study dose with CTC (49.5%) versus tramadol (61.7%, p = 0.0178), celecoxib (65.2%, p = 0.0024), and placebo (75.3%, p = 0.0001); this was also seen for oxycodone use. Fewer patients in the CTC group received ≥3 doses of rescue medication compared with the other groups, irrespective of baseline pain intensity. In patients who did not receive opioid rescue medication, CTC was associated with a lower incidence of nausea and vomiting TEAEs versus tramadol alone. In patients who received rescue oxycodone, the incidence of nausea was similar in the CTC and tramadol groups, and higher versus celecoxib and placebo. CONCLUSION: Celecoxib-tramadol co-crystal was associated with reduced rescue medication use and an acceptable tolerability profile compared with tramadol or celecoxib alone in adults with acute, moderate-to-severe, postoperative pain.

Consumer awareness and knowledge regarding use of non-steroidal anti-inflammatory drugs (NSAIDs) in a metropolitan area.

Background: Non-steroidal anti-inflammatory drugs (NSAIDs) have well-known adverse effects, and numerous studies have shown inappropriate behaviors regarding their use. The primary aim of this study was to analyze the knowledge, attitudes, and behaviors regarding the use of NSAIDs simultaneously in one of the largest and most populated areas of Italy, Naples. Methods: From 2021 December 14th to 2022 January 4th, a cross-sectional survey study was conducted among community centers, working places, and universities using a snowball sampling method. For inclusion in the study, the participants were required to be at least 18 years old and residents in the metropolitan area of Naples. Three multiple linear regression analysis (MLRA) models were developed by including variables that could potentially be associated with the following outcomes of interest: knowledge (Model I), attitudes (Model II), and behavior (Model III) regarding the use of NSAIDs. Results: Data were acquired from 1,012 questionnaires administered to subjects evenly divided by gender with an average age of 36.8 years and revealed that only 7.9% of the participants self-admittedly did not take NSAIDs, while approximately half the participants (50%) admitted to occasionally using them. The results showed a statistically significant correlation between attitudes regarding the appropriate use of NSAIDs and less knowledge. The regression analyses indicated that behaviors regarding the appropriate use of NSAIDs were statistically significant in younger respondents, non-smokers, and those without children. These interesting results showed that behaviors regarding the appropriate use of NSAIDs were significantly higher among respondents with less knowledge and more positive attitudes. Conclusion: According to the collected data and statistical analysis results, it is possible to identify factors that can greatly affect inappropriate behaviors regarding the use of NSAIDs and establish targeted prevention programs.

Design of double-core-shell structural materials for the extraction of non-steroidal anti-inflammatory drugs.

In this work, core-shell material with a special structure was designed and applied in solid-phase extraction (SPE) for non-steroidal anti-inflammatory drugs (NSAIDs) combined with high-performance liquid chromatography. Based on the advantages of core-shell ZIF-8@ZIF-67 (Zeolite imidazole ester framework materials [ZIFs]), effective derivatization treatment was carried out to partially vulcanize the original ZIFs, resulting in a special and new double-core-shell structural material CoS/ZIF-67/ZnS/ZIF-8 (ZIFs@ZnS@CoS) with porous surface and center hollow. The multiple forces caused by the rich chemical structure, the large specific surface area caused by the special pore structure, and the effective protection of the ZIFs core by sulfide shell make the designed material have higher extraction efficiency and longer service life, compared with ZIF-8@ZIF-67 and ZIF-8. At the same time, the established analytical method for non-steroidal drugs had a high recovery rate (98.93%-102.10%), low detection limit (0.11-0.27 µg/L), and wide linear range (1-200 µg/L) within a good correlation coefficient R2 (0.9978-0.9993). Satisfactory results were also obtained from the extraction of NSAIDs from the Yellow River water samples. These results indicate that the designed double-core-shell structure material can effectively exert its structural advantages and become a promising extraction material.

Non-Steroidal Anti-Inflammatory Drugs in the Aquatic Environment and Bivalves: The State of the Art.

In recent years, contaminants of emerging concern have been reported in several environmental matrices due to advances in analytical methodologies. These anthropogenic micropollutants are detected at residual levels, representing an ecotoxicological threat to aquatic ecosystems. In particular, the pharmacotherapeutic group of non-steroidal anti-inflammatories (NSAIDs) is one of the most prescribed and used, as well as one of the most frequently detected in the aquatic environment. Bivalves have several benefits as a foodstuff, and also as an environment bioindicator species. Therefore, they are regarded as an ideal tool to assess this issue from both ecotoxicological and food safety perspectives. Thus, the control of these residues in bivalves is extremely important to safeguard environmental health, also ensuring food safety and public health. This paper aims to review NSAIDs in bivalves, observing their consumption, physicochemical characteristics, and mechanisms of action; their environmental occurrence in the aquatic environment and aquatic biota; and their effects on the ecosystem and the existent legal framework. A review of the analytical methodologies for the determination of NSAIDs in bivalves is also presented.

Beneficial effect of metformin on tolerance to analgesic effects of sodium salicylate in male rats.

Background: Tolerance to the analgesic effects of opioids and non-steroidal anti-inflammatory drugs (NSAIDs) is a major concern for relieving pain. Thus, it is highly valuable to find new pharmacological strategies for prolonged therapeutic procedures. Biguanide-type drugs such as metformin (MET) are effective for neuroprotection and can be beneficial for addressing opioid tolerance in the treatment of chronic pain. It has been proposed that analgesic tolerance to NSAIDs is mediated by the endogenous opioid system. According to the cross-tolerance between NSAIDs, especially sodium salicylate (SS), and opiates, especially morphine, the objective of this study was to investigate whether MET administration can reduce tolerance to the anti-nociceptive effects of SS. Methods: Fifty-six male Wistar rats were used in this research (weight 200-250 g). For induction of tolerance, SS (300 mg/kg) was injected intraperitoneally for 7 days. During the examination period, animals received MET at doses of 50, 75, or 100 mg/kg for 7 days to evaluate the development of tolerance to the analgesic effect of SS. The hot plate test was used to evaluate the drugs' anti-nociceptive properties. Results: Salicylate injection significantly increased hot plate latency as compared to the control group, but the total analgesic effect of co-treatment with SS + Met50 was stronger than the SS group. Furthermore, the effect of this combination undergoes less analgesic tolerance over time. Conclusions: It can be concluded that MET can reduce the analgesic tolerance that is induced by repeated intraperitoneal injections of SS in Wister rats.

Exploring potential neuroimaging biomarkers for the response to non-steroidal anti-inflammatory drugs in episodic migraine.

BACKGROUND: Non-steroidal anti-inflammatory drugs (NSAIDs) are considered first-line medications for acute migraine attacks. However, the response exhibits considerable variability among individuals. Thus, this study aimed to explore a machine learning model based on the percentage of amplitude oscillations (PerAF) and gray matter volume (GMV) to predict the response to NSAIDs in migraine treatment. METHODS: Propensity score matching was adopted to match patients having migraine with response and nonresponse to NSAIDs, ensuring consistency in clinical characteristics and migraine-related features. Multimodal magnetic resonance imaging was employed to extract PerAF and GMV, followed by feature selection using the least absolute shrinkage and selection operator regression and recursive feature elimination algorithms. Multiple predictive models were constructed and the final model with the smallest predictive residuals was chosen. The model performance was evaluated using the area under the receiver operating characteristic (ROCAUC) curve, area under the precision-recall curve (PRAUC), balance accuracy (BACC), sensitivity, F1 score, positive predictive value (PPV), and negative predictive value (NPV). External validation was performed using a public database. Then, correlation analysis was performed between the neuroimaging predictors and clinical features in migraine. RESULTS: One hundred eighteen patients with migraine (59 responders and 59 non-responders) were enrolled. Six features (PerAF of left insula and left transverse temporal gyrus; and GMV of right superior frontal gyrus, left postcentral gyrus, right postcentral gyrus, and left precuneus) were observed. The random forest model with the lowest predictive residuals was selected and model metrics (ROCAUC, PRAUC, BACC, sensitivity, F1 score, PPV, and NPV) in the training and testing groups were 0.982, 0.983, 0.927, 0.976, 0.930, 0.889, and 0.973; and 0.711, 0.648, 0.639, 0.667,0.649, 0.632, and 0.647, respectively. The model metrics of external validation were 0.631, 0.651, 0.611, 0.808, 0.656, 0.553, and 0.706. Additionally, a significant positive correlation was found between the GMV of the left precuneus and attack time in non-responders. CONCLUSIONS: Our findings suggest the potential of multimodal neuroimaging features in predicting the efficacy of NSAIDs in migraine treatment and provide novel insights into the neural mechanisms underlying migraine and its optimized treatment strategy.

Corneal Melt and Perforation Associated With Prolonged Oral Non-Steroidal Anti-Inflammatory Drug (NSAID) Use: A Case Report.

Corneal melt and perforation can arise from various etiologies, including the use of toxic topical drops, particularly topical non-steroidal anti-inflammatory drugs (NSAIDs). The literature has frequently documented the association between the use of topical NSAIDs and the subsequent development of corneal ulcers. More recently, reports have emerged linking the use of oral NSAIDs and colchicine to impaired corneal wound healing and corneal perforation. This case report presents an instance of corneal melting and subsequent perforation in a medically unburdened patient who had been self-administering oral NSAIDs for one year. The evidence presented in this report suggests a plausible association between the prolonged administration of oral NSAIDs and corneal melt. Consequently, healthcare practitioners should be mindful of this potential risk when considering the prolonged use of oral NSAIDs.

NOSH-aspirin (NBS-1120) inhibits estrogen receptor negative breast cancer in vitro and in vivo by modulating redox-sensitive signaling pathways.

Estrogen receptor (ER)-negative breast cancers are known to be aggressive and unresponsive to anti-estrogen therapy, and triple negative breast cancers are associated with poor prognosis and metastasis. Thus, new targeted therapies are needed. FOXM1 is abundantly expressed in human cancers and implicated in protecting tumor cells from oxidative stress by reducing the levels of intracellular reactive oxygen species (ROS). Aspirin, a prototypical anti-cancer agent with deleterious side effects, has been modified to release nitric oxide and hydrogen sulfide, called NOSH-aspirin (NOSH-ASA), generating a 'safer' class of new anti-inflammatory agents. We evaluated NOSH-ASA against (ER)-negative breast cancer using cell lines and a xenograft mouse model. NOSH-ASA strongly inhibited growth of MDA-MB-231 and SKBR3 breast cancer cells with low IC50s of 90{plus minus}5 and 82{plus minus}5 nM, respectively, with marginal effects on a normal breast epithelial cell line. NOSH-ASA inhibited cell proliferation, caused G0/G1 phase arrest, increased apoptosis, and was associated with increases in ROS. In MDA-MB-231 cell xenografts, NOSH-ASA reduced tumor size markedly, which was associated with reduced proliferation (decreased PCNA expression), induction of apoptosis (increased TUNEL positive cells), and increased ROS, while NF-kB and FoxM1 that were high in untreated xenografts were significantly reduced. mRNA data for FoxM1, p21 and CyclinD1 corroborated with the respective protein expressions and arrest of cells. Taken together, these molecular events contribute to NOSH-ASA mediated growth inhibition and apoptotic death of (ER)-negative breast cells in vitro and in vivo. Additionally, as a ROS-inducer and FOXM1-inhibitor, NOSH-ASA has potential as a targeted therapy. Significance Statement In this investigation, we examined the cellular effects and xenograft tumor inhibitory potential of NOSH-aspirin, an NO and H2S-donating hybrid, against ER-negative breast cancer, which currently lacks effective therapeutic options. The induction of reactive oxygen species and subsequent downregulation of FOXM1 represents a plausible mechanism contributing to the observed decrease in cell proliferation and concurrent increase in apoptosis. NOSH-ASA demonstrated a remarkable reduction in tumor size by 90% without inducing any observable gross toxicity, underscoring its promising translational potential.

A Comprehensive Meta-Analysis on the Role of Analgesics and Anti-Inflammatories in Pan-retinal Photocoagulation.

PURPOSE: Pan-retinal photocoagulation (PRP) is the mainstay of treatment for proliferative diabetic retinopathy (PDR), reducing the risk of severe vision loss. Pain poses a potential obstacle to effective laser delivery and patient compliance. Therefore, implementing pain relief strategies can enhance both treatment efficacy and patient comfort. DESIGN: A systematic review and meta-analysis. METHODS: We conducted a systematic review and meta-analysis according to PRISMA guidelines. The PubMed, Embase and Cochrane Central Register of Controlled Trials databases were searched for randomized controlled trials (RCTs) that enrolled patients undergoing PRP due to DR and compared analgesics or non-steroidal anti-inflammatory drugs (NSAID) to placebo. Pain was evaluated with the visual analogue scale. The version 2 of the Cochrane Collaboration's Risk of Bias in Randomized Controlled Trials tool and its version for crossover trials were used to assess the risk of bias. The Grading of Recommendations, Assessment, Development, and Evaluation tool was used to measure the certainty of evidence. RESULTS: A total of 13 studies were included, comprising 1404 eyes from RCTs, nine of which were crossover. Patients who were administered analgesia reported a significantly lower pain sensitivity compared to those who received placebo (Standardized mean difference [SMD] -0.38; 95% confidence interval [CI] -0.58, -0.17; P<0.01; I2=69%). Subgroup analysis of systemic administration of analgesics/NSAIDs (metamizole, Entonox, acetaminophen, ibuprofen, caffeine, mefenamic acid, intramuscular ketorolac tromethamine, and potassium diclofenac) also showed a statistically significant reduction in pain when compared to placebo (SMD -0.28; 95% CI -0.50, -0.07; P<0.01; I2=43%). Exclusive eye drops administration (ketorolac tromethamine 0.5% and sodium diclofenac 0.1%) also showed a significant difference in pain sensitivity (SMD -0.46; 95% CI -0.88, -0.05; I2=83%), however with a more significant heterogeneity. CONCLUSION: The results of this meta-analysis including over 1000 patients demonstrated that the use of analgesics significantly reduced pain sensitivity during PRP, and systemic analgesia is potentially better than topical administration when compared to placebo.

Association of Cytokines with Clinical Indicators in Patients with Drug-Induced Liver Injury.

Objective: To explore characteristics of clinical parameters and cytokines in patients with drug-induced liver injury (DILI) caused by different drugs and their correlation with clinical indicators. Method: The study was conducted on patients who were up to Review of Uncertainties in Confidence Assessment for Medical Tests (RUCAM) scoring criteria and clinically diagnosed with DILI. Based on Chinese herbal medicine, cardiovascular drugs, non-steroidal anti-inflammatory drugs (NSAIDs), anti-infective drugs, and other drugs, patients were divided into five groups. Cytokines were measured by Luminex technology. Baseline characteristics of clinical biochemical indicators and cytokines in DILI patients and their correlation were analyzed. Results: 73 patients were enrolled. Age among five groups was statistically different ( P = 0.032). Alanine aminotransferase (ALT) ( P = 0.033) and aspartate aminotransferase (AST) ( P = 0.007) in NSAIDs group were higher than those in chinese herbal medicine group. Interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) in patients with Chinese herbal medicine (IL-6: P < 0.001; TNF-α: P < 0.001) and cardiovascular medicine (IL-6: P = 0.020; TNF-α: P = 0.001) were lower than those in NSAIDs group. There was a positive correlation between ALT ( r = 0.697, P = 0.025), AST ( r = 0.721, P = 0.019), and IL-6 in NSAIDs group. Conclusion: Older age may be more prone to DILI. Patients with NSAIDs have more severe liver damage in early stages of DILI, TNF-α and IL-6 may partake the inflammatory process of DILI.

Comparison of the Efficacy of Omalizumab and Mepolizumab in Non-Steroidal Anti-Inflammatory Drug-Exacerbated Respiratory Disease.

INTRODUCTION: Non-steroidal anti-inflammatory drug-exacerbated respiratory disease (N-ERD) is heterogeneous in both phenotypes and endotypes. Due to insufficient head-to-head comparison studies, it is hard to decide which biological to initiate. This study aimed to compare the efficacy of omalizumab and mepolizumab which can be used in the treatment of patients with severe eosinophilic asthma diagnosed with N-ERD. METHODS: The population of this observational, cross-sectional study comprised of N-ERD patients who received omalizumab or mepolizumab for at least 6 months for severe asthma. Outcomes included the asthma control test (ACT), and sino-nasal outcome test scores (SNOT-22), blood eosinophil counts at initiation of biological treatment (T0, baseline) and at the end of 6th months (T6). Adverse effects related to biological treatment and changes of oral corticosteroids dose was recorded. RESULTS: The study included a total of 22 patients, of whom 11 received mepolizumab and 11 received omalizumab. The change in ACT, SNOT-22, eosinophil counts, and adverse effects related to biologicals were similar at T6 (p = 0.606, p = 0.168, p = 0.05, p = 0.053, respectively). However, when examining the SNOT-22 and ACT based on the cumulative distribution curve (SUCRA), mepolizumab (SUCRA value: 0.61, 0.72, respectively) demonstrated greater efficacy compared to omalizumab (SUCRA value: 0.19, 0.35, respectively). The oral corticosteroids discontinuation rate was similar between the two groups (p = 0.05). CONCLUSION: We found both omalizumab and mepolizumab to be effective in treatment; however, we determined that mepolizumab may have a potential superiority in efficacy.

Infectious Mononucleosis Revealed by Non-steroidal Anti-inflammatory Drug: A First Clinical Report.

Infectious mononucleosis (IM), primarily caused by the Epstein-Barr virus (EBV), is a common viral illness among adolescents and young adults. IM typically presents with symptoms such as fever, lymphadenopathy, and pharyngitis. We present a case of a 32-year-old woman who developed a maculopapular rash following ibuprofen administration, revealing an underlying undiagnosed IM. Laboratory investigations confirmed EBV infection. This represents the first documented case linking non-steroidal anti-inflammatory drugs (NSAIDs) to IM presentation. Awareness of this association is crucial for timely diagnosis and management, especially when evaluating patients with unexplained skin reactions to medications.

[Expert consensus on the diagnosis and treatment of respiratory diseases exacerbated by nonsteroidal anti-inflammatory drugs （2024, Chengdu）].

Non-steroidal anti-inflammatory drugs-exacerbated respiratory disease （N-ERD） is a chronic respiratory disease characterized by eosinophilic inflammation, featuring chronic rhinosinusitis （CRS）, asthma, and intolerance to cyclooxygenase 1 （COX-1） inhibitors. The use of these medications can lead to an acute worsening of rhinitis and asthma symptoms. This condition has not yet received sufficient attention in China, with a high rate of misdiagnosis and a lack of related research. The Chinese Rhinology Research Group convened a group of leading young experts in otolaryngology from across the country, based on the latest domestic and international evidence-based medical practices to formulate this consensus.The consensus covers the epidemiology, pathogenesis, clinical manifestations, diagnostic methods, and treatment strategies for N-ERD, including pharmacotherapy, surgery, biologic treatments, and desensitization therapy. The goal is to improve recognition of N-ERD, reduce misdiagnosis, and enhance treatment outcomes.

Design and baseline characteristics of the Finerenone, in addition to standard of care, on the progression of kidney disease in patients with Non-Diabetic Chronic Kidney Disease (FIND-CKD) randomized trial.

BACKGROUND AND HYPOTHESIS: Finerenone, a non-steroidal mineralocorticoid receptor antagonist, improved kidney, and cardiovascular outcomes in patients with CKD and T2D in two Phase 3 outcome trials. The FIND-CKD study investigates the effect of finerenone in adults with CKD without diabetes. METHODS: FIND-CKD (NCT05047263 and EU CT 2023-506897-11-00) is a randomized, double-blind, placebo-controlled Phase 3 trial in patients with CKD of non-diabetic aetiology. Adults with a urinary albumin-creatinine ratio (UACR) of ≥ 200 to ≤3500 mg/g and eGFR ≥ 25 to <90 mL/min/1.73 m2 receiving a maximum tolerated dose of a renin-angiotensin-system (RAS) inhibitor were randomized 1:1 to once daily placebo or finerenone 10 or 20 mg depending on eGFR above or below 60 mL/min/1.73 m2. The primary efficacy outcome is total eGFR slope, defined as the mean annual rate of change in eGFR from baseline to Month 32. Secondary efficacy outcomes include a combined cardiorenal composite outcome comprising time to kidney failure, sustained ≥57% decrease in eGFR, hospitalization for heart failure, or cardiovascular death, as well as separate kidney and cardiovascular composite outcomes. Adverse events are recorded to assess tolerability and safety. RESULTS: Across 24 countries, 3231 patients were screened and 1584 were randomized to study treatment. The most common causes of CKD were chronic glomerulonephritis (57.0%) and hypertensive/ischaemic nephropathy (29.0%). Immunoglobulin A nephropathy was the most common glomerulonephritis (26.3% of the total population). At baseline, mean eGFR and median UACR were 46.7 mL/min/1.73 m2 and 818.9 mg/g, respectively. Diuretics were used by 282 participants (17.8%), statins by 851 (53.7%), and calcium channel blockers by 794 (50.1%). SGLT2 inhibitors were used in 16.9% of patients; these individuals had a similar mean eGFR (45.6 vs 46.8 mL/min/1.73 m2) and slightly higher median UACR (871.9 vs 808.3 mg/g) compared to those not using SGLT2 inhibitors at baseline. CONCLUSIONS: FIND-CKD is the first Phase 3 trial of finerenone in patients with CKD of non-diabetic aetiology.

Inter-Semispinalis Plane Block Versus General Anesthesia for Postoperative Analgesia in Posterior Cervical Spine Surgery: A Randomized Controlled Trial.

Background: Postoperative pain management is crucial for improving patient outcomes following posterior cervical spine surgery. Opioids are effective but carry a risk of respiratory depression. Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used but may not provide adequate pain relief and have potential complications. The inter-semispinalis plane (ISPB) block is a novel technique for postoperative analgesia in cervical spine surgery. Objectives: This study aims to evaluate and compare the efficacy of the ISPB with general anesthesia in terms of analgesia, postoperative Visual Analog Scale (VAS) pain scores, patient-surgeon satisfaction levels, and the occurrence of postoperative complications. Methods: This double-blind, randomized controlled trial was blinded to both the patient and the assessor. Fifty adult patients (18 - 60 years old) undergoing elective posterior cervical spine surgery were enrolled. The participants were divided into 2 groups: The ISPB group (receiving bilateral ultrasound-guided ISPB at the C5 level) and the control group (receiving general anesthesia only), with each group comprising 25 patients. The study assessed intraoperative fentanyl use, postoperative VAS pain levels, the need for rescue analgesia, and complications. Results: The ISPB group showed significantly lower intraoperative fentanyl consumption (median 100 vs. 100 - 150 µg, P = 0.022) and lower postoperative pain scores at 1, 8, 12, and 48 hours (P = 0.016, 0.009, 0.005, 0.016). Additionally, the ISPB group required less postoperative pethidine (20% vs. 64%, P = 0.002) and had a longer delay before requesting pethidine (hazard ratio 0.215, P = 0.001). Surgeon satisfaction was significantly higher in the ISPB group (P = 0.003). These results suggest that the ISPB can effectively reduce pain and analgesic requirements. Conclusions: The ISPB is an effective analgesic technique for posterior cervical spine surgery, reducing opioid consumption, providing better pain control, and enhancing surgeon satisfaction without increasing complications. This approach has the potential to improve postoperative care and patient outcomes in this surgical population.

Dexamethasone and chronic postsurgical pain: the pendulum meets reductionistic thinking.

Reductionist thinking results in the bulk of anaesthesia trial designs being a single intervention to address what are in fact complex processes. The Perioperative Administration of Dexamethasone and Infection (PADDI) trial assessed the safety of a single preoperative dose of dexamethasone. Surprising to most, in the original report, a single dose of dexamethasone increased the incidence of the secondary outcome chronic postsurgical pain. Was this a chance finding or does dexamethasone increase chronic postsurgical pain? In an attempt to address this question, the PADDI investigators have now analysed this prespecified secondary outcome in two ways: as a substudy published earlier in this Journal, and as a retrospective analysis of the ENIGMA-II chronic pain database in this issue of the Journal. The PADDI investigators have now presented enough data to convince us that indeed a single dose of dexamethasone is safe and effective. However, the increase in chronic postsurgical pain seen in the original PADDI publication highlights the complexities, and the possible immunologic mechanisms, behind the genesis of chronic postsurgical pain. These publications from the PADDI group raise questions about other anti-inflammatory agents we use regularly for long-term postoperative pain management, and highlights the need for well-designed clinical trials to address this critically important patient-centred adverse functional outcome.

[Renal colic]. / Steinkolik.

INTRODUCTION: Renal colic accounts for 5-10% of all emergency department visits, making it a common condition in acute medicine. The typical clinical presentation is an early indication of urolithiasis. DIAGNOSIS: Diagnostic measures include laboratory tests, ultrasound, and low-dose noncontrast computed tomography (CT) scans. Kidney, ureter, bladder (KUB) plain film radiography has been widely replaced by low-dose noncontrast CT with similar radiation dosage. In special patient groups such as children or pregnant women, ionizing radiation should be avoided if possible. TREATMENT: General measures involve pain management (non-steroidal anti-inflammatory agents, opioids) and empirical antibiotic treatment for suspected bacterial infection. Depending on the location/size of the stone, pharmacological stone expulsion therapy may be considered. In cases of obstructive pyelonephritis or acute renal insufficiency, early urinary drainage (JJ stent/nephrostomy) is recommended. Definitive stone removal may be performed primarily in some cases (rather small and rather distal ureterolithiasis). It is common to schedule stone removal as a secondary intervention.

Reactive oxygen species induced by indomethacin enhance accumulation of heme carrier protein 1 and hematoporphyrin accumulation in vitro and in vivo in a brain tumor model.

Photodynamic therapy (PDT) is useful for various cancers such as high-grade glioma and cancers of other organs. However, the mechanism of tumor-specific accumulation of porphyrin is not clear. The authors previously reported that heme carrier protein 1 (HCP1) contributes to the transport of porphyrins; specifically, we showed that the production of cancer-specific reactive oxygen species from mitochondria (mitROS) leads in turn to enhanced HCP1 expression. Indomethacin (IND), a non-steroidal anti-inflammatory drug, increases ROS production by affecting mitochondrial electron transfer system. In the present work, the authors investigated the effect of pretreatment with IND on cancer-specific porphyrin accumulation, using both a glioma cell line and a rat brain tumor model. This work demonstrated that exposure of a rat glioma cell to IND results in increased generation of cancer-specific mitROS and accumulation of HCP1 expression and porphyrin concentration. Additionally, systemic dosing of a brain tumor animal model with IND resulted in elevated cellular accumulation of porphyrin in tumor cell. This is an effect not seen with normal brain tissue. Thus, the administration of IND increases intracellular porphyrin concentrations in tumor cell without exerting harmful effects on normal brain tissue, and increased porphyrin concentration in tumor cell may lead to improved PDT effect.
