Comparison of The Effectiveness of Thymoquinone, St. John Wort Oil and Silver Sulfadiazine in Experimental Burn Wounds.

We aimed to compare the effectiveness of thymoquinone (TQ), most important bioactive component of black cumin, St. John wort (SJW) oil, a traditional medicinal plant used in burns, and silver sulfadiazine (AgSD), well-known anti-inflammatory agent used in modern medicine, in an experimental burn rat-model. 63 Wistar-Albino rats were randomly divided into 9 groups (n=7). TQ, SJW were administered topically and systemically but AgSD was applied topically. Epithelialization, inflammatory cell response, granulation tissue, vascularization, and fibrosis were evaluated. Malondialdehyde (MDA), total antioxidant status (TAS), total oxidant status (TOS), vitamin E, 8-hydroxy-deoxyguanosine (8-OHdG), coenzyme Q10 (CoQ10) were analyzed in serum. Topical TQ accelerated theepithelialization, enabled granulation, vascularization and fibrosis in wounds (P=0.001). Topical and systemic TQ increased Vitamin-E levels (P=0.003) but reduced TOS and 8-OHdG levels (P=0.001). Topical SJW reduced granulation and vascularization. Topical and systemic SJW decreased TOS, MDA and 8-OHdG levels (P=0.001), but increased TAS (P=0.001), and Vitamin-E levels (P=0.003). Topical AgSD reduced TOS, 8-OHdG, MDA levels (P=0.001). Topical and systemic TQ demonstrated significant advantages in accelerating wound healing process, while also enhancing antioxidant defenses and reducing oxidative damage. SJW oil, particularly in topical application, improved epithelialization and antioxidant status but showed less efficacy in systemic use. AgSD, while effective in reducing oxidative stress, was less successful in promoting wound healing and appeared to delay granulation and fibrosis. TQ offers superior protective and healing benefits, SJW is effective locally but less so systemically, and AgSD should be used cautiously, potentially combined with antioxidants to mitigate its negative impact on wound healing.

Computational and biological evaluation of naphthofuran-based scaffold as an anti-inflammatory agent

Naphthofuran derivatives can reduce inflammation by inhibiting prostaglandins and cytokines. They also modulate immune cell activity and scavenge reactive oxygen species to alleviate oxidative stress-induced inflammation. In this study, we evaluated the anti-inflammatory potential of a naphthofuran-based derivative, 2-phenyl-1-(phenylthio)naphtho[2,1-b]furan (PTNF), to inhibit nitric oxide (NO) and its impact on the production of pro-inflammatory cytokines TNF-α and IL-6. In addition to 6–311++G(d,p) basis set, quantum mechanical calculations were carried out to explain the geometry and stability of the PTNF using DFT at the B3LYP level. Molecular docking investigations revealed that PTNF exhibited strong binding interactions with TNF-α and IL-6. These results emphasize the potential of naphthofuran derivatives in shaping future therapeutic approaches, specifically for addressing inflammatory diseases.

Sulfated Chinese yam polysaccharide exert anti-inflammatory potential via MAPK/NF-κB signaling pathways in a co-culture system and LPS-induced acute inflammatory mice model.

Our previous study has demonstrated that sulfated Chinese yam polysaccharide (SCYP) can improve immunomodulatory activity in Raw 264.7 cells. However, its anti-inflammatory is little known. In this study, the anti-inflammatory effects of SCYP were systematically investigated via the Lipopolysaccharides (LPS)-induced Raw264.7 cell model, Caco-2/Raw264.7 co-culture system, and acute inflammation mice model. The results suggested SCYP promoted the cell proliferation and have no toxicity in Raw264.7 and Caco-2 cells at the concentration of 200µg/mL. Moreover, when treated with SCYP, the production of pro-inflammatory cytokines (interleukin [IL]-1β, IL-6, and tumor necrosis factor-α) reduced significantly in Raw264.7 via the MAPK/NF-κB pathway. In the Caco-2/Raw264.7 co-cultured system, SCYP could regulate inflammation reaction by improving intestinal barrier, which might prevent systemic inflammation. Further, systemic inflammation was alleviated by SCYP in LPS-induced acute inflammation mice through MAPK/NF-κB pathway. PRACTICAL APPLICATION: These results supported that SCYP may be used as an anti-inflammation agent in the functional food field.

Application of microbial enzymes in medicine and industry: current status and future perspectives.

Microbes are a major source of enzymes due to their ability to be mass-cultivated and genetically modified. Compared with plant and animal enzymes, microbial enzymes are more stable and active. Enzymes are generally classified into six classes based on their reaction, substrate specificity and mechanism of action. In addition to their application in medicine for treating diseases, these compounds are used as anti-inflammatory, thrombolytic and digestive agents. However, challenges such as immunogenicity, tissue specificity and short in vivo half-life make clinical trials complex. Enzymes are metabolic catalysts in industry and their production and extraction must be optimized to preserve profitability due to rising demand. The present review highlights the increasing importance of bacterial enzymes in industry and medicine and explores methods for their production, extraction and purification.

276 Use of triaxial accelerometers and a machine learning algorithm for behavioral identification to assess the effectiveness of a joint supplement in old domestic cats (Felis catus)

Abstract Degenerative joint disease (DJD) has a 90% prevalence in older cats and adversely affects quality of life1. Long-term administration of non-steroidal anti-inflammatory drugs is usually required but can have adverse effects2. Nutraceuticals have been shown to relieve joint pain in cats without such side effects; however, due to differences in dose rates and formulations there is no consensus as to their efficacy. Most studies have utilized subjective insensitive measures such as veterinary or owner-assessed changes in activity. Accelerometers can provide objective data on cat activity and can identify specific behaviors3.Triaxial accelerometers (ActiGraph, Pensacola, FL) were fitted to the collars of 16 cats (aged 11 to 16 yr; Massey University, Palmerston North, NZ) for 20 wk to assess their activity and behavior. The cats were fed the same diet (Chef: Kraft Heinz Wattie’s Ltd., Hastings, NZ) for 4 wk to collect baseline acceleration data, before being divided into two groups balanced for physical activity. After 4 wk, a blood sample were taken from all of the cats to establish their baseline levels of a range of inflammatory markers (e.g., IL-6, TNFα, INF- γ, SDF-1). The test group (n = 8) then received a joint supplement added to the baseline diet while the control group (n = 8) were fed the diet unsupplemented for 16 wk. The commercial joint supplement contained glucosamine, chondroitin sulphate, and green-lipped mussel (Tandem, Wellington, NZ), at daily doses shown previously to be effective in cats4,5,6. The aim of the work was to assess the efficacy of the joint supplement in maintaining or promoting activity and specific behaviors in the cats. At the end of the period of supplementation a second blood sample was taken and assessed for the same range of inflammatory markers. Overall physical activity was not different between groups at baseline but was greater over the study in the test group compared with the control (P < 0.03). Grooming, as identified by the algorithm, showed a tendency (P = 0.051) to be greater in the test group than the control. These results suggest that the supplement had a positive effect on both overall activity and more specifically on grooming behavior in old cats. However, no differences in the range of inflammatory markers were seen before or after supplementation. While the behavioral measures could indicate the supplement reduced the effects of DJD, further research is required to confirm this.1Cunningham et al (2022) Journal of Feline Medicine and Surgery 24, 962-974. 2Lemetayer and Taylor (2014) Journal of Feline Medicine and Surgery 16, 547-562; 3Smit et al., (2023) Sensors 23, 7165; 4Corbee (2022) Veterinary Medicine and Science 8, 1025–1035; 5Corbee et al.

A pharmacovigilance study on clinical factors of active vitamin D3 analog-related acute kidney injury using the Japanese Adverse Drug Event Report Database

Acute kidney injury (AKI) due to vitamin D therapy for osteoporosis is encountered in clinical practice, but epidemiological studies are scarce. We aimed to determine the association between AKI and vitamin D therapy and to identify risk factors for AKI using the Japanese Adverse Drug Event Report database. We used reporting odds ratios (RORs) to detect signals and evaluate risk factors using multiple logistic regression analysis. Among 298,891 reports from April 2004 to September 2023, 1071 implicated active vitamin D3 analogs as suspect drugs for adverse events. There was a significant association between AKI and active vitamin D3 analogs (ROR [95% confidence interval {CI}], eldecalcitol: 16.75 [14.23–19.72], P < 0.001; alfacalcidol: 5.29 [4.07–6.87], P < 0.001; calcitriol: 4.46 [1.88–10.59], P < 0.001). The median duration of administration before AKI onset was 15.4 weeks. Multiple logistic regression analysis showed a significant association between AKI and age ≥ 70 years (odds ratio [95% CI], 1.47 [1.04–2.07]; P = 0.028), weight < 50 kg (1.55 [1.12–2.13]; P = 0.007), hypertension (1.90 [1.42–2.54]; P < 0.001), and concomitant use of nonsteroidal anti-inflammatory drugs (1.58 [1.10–2.25], P = 0.012) and magnesium oxide (1.96 [1.38–2.78]; P < 0.001). Our results suggest that active vitamin D3 analogs are associated with AKI development. Physicians prescribing these medications to patients with risk factors should consider the possibility of AKI, especially during the first 6 months.

Emergency Department Use of Heart Failure-Exacerbating Medications in Patients with Chronic Heart Failure.

Use of heart failure-exacerbating medications (HFEMs) may lead to preventable episodes of acute decompensated heart failure (HF). HFEMs use is common in patients with HF, and there may be opportunities to reduce their use from the emergency department (ED). We performed an observational study on patients with HF presenting to EDs within a healthcare system between 1 January 2016 and 31 December 2020. Patients with chronic HF were identified using diagnostic codes within the electronic health record. The cohort was restricted to ambulatory (i.e., discharged to home) ED encounters. Medications, either ordered in the ED or prescribed at ED discharge, were extracted from the medication administration record and identified as potential HFEMs based on the 2016 American Heart Association Scientific Statement. Descriptive statistics were used to summarize the prevalence of HFEM use during ambulatory ED encounters. Exploratory analyses to identify correlates of HFEM use were performed. The study cohort included 23,907 ED encounters. ED administration or prescription of HFEMs occurred during 20% of ambulatory ED encounters. HFEM administration in the ED (17%) was more common than HFEM prescription at ED discharge (6%). The most common HFEMs administered in the ED included nonsteroidal anti-inflammatory drugs (11%) and albuterol (7%). HFEM use is common in patients with HF seeking ED care, occurring in roughly one-fifth of ambulatory ED encounters. There may be opportunities to optimize medication use among patients with HF in the ED.

Solubility and thermodynamic analysis of aceclofenac in different {Carbitol + water} mixtures at various temperatures

The solubility and thermodynamic properties of the anti-inflammatory drug aceclofenace (ACF) have been assessed in a range of {2-(2-ethoxyethoxy)ethanol (Carbitol) + water} combinations at temperatures ranging from 298.2 K to 318.2 K and atmospheric pressure of 101.1 kPa. The shake flask method was employed to determine the solubility of ACF, and various models including “van’t Hoff, Apelblat, Buchowski-Ksiazczak λh, Yalkowsky-Roseman, Jouyban-Acree, and Jouyban-Acree-van’t Hoff models” were used to validate the results. The computational models demonstrated a strong correlation with the experimental ACF solubility data, as indicated by the error values of < 3.0%. In the compositions of {Carbitol + water}, the ACF mole fraction solubility was enhanced by temperature and Carbitol mass fraction. The solubility of ACF in mole fraction was found to be lowest in pure water (1.07 × 10− 6 at 298.2 K), and highest in pure Carbitol (1.04 × 10− 1 at 318.2 K). Based on the positive values of the calculated thermodynamic parameters, the dissolution of ACF was determined to be “endothermic and entropy-driven” in all of the {Carbitol + water} solutions that were studied. It was also observed that enthalpy controls the solvation of ACF in solutions containing {Carbitol + water}. ACF-Carbitol had the strongest molecular interactions in contrast to ACF-water. Based on the results of this study, Carbitol holds significant potential for enhancing the solubility of ACF in water.

Discovery of the therapeutic potential of PPARδ agonist bearing 1,3,4- thiadiazole in inflammatory disorders

As a defense mechanism against deleterious stimuli, inflammation plays a vital role in the development of many disorders, including atherosclerosis, inflammatory bowel disease, experimental autoimmune encephalomyelitis, septic and non-septic shock, and non-alcoholic fatty liver disease (NAFLD). Despite the serious adverse effects of extended usage, traditional anti-inflammatory medications, such as steroidal and non-steroidal anti-inflammatory medicines (NSAIDs), are commonly used for alleviating symptoms of inflammation. The PPARδ subtype of peroxisome proliferator-activated receptors (PPARs) has attracted interest because of its potential for reducing inflammation and related disorders. In this study, a series of 1,3,4-thiadiazole derivatives were designed, synthesized, and evaluated. Compound 11 exhibited potent PPARδ agonistic activity with EC50 values 20 nM and strong selectivity over PPARα and PPARγ. Furthermore, compound 11 demonstrated favorable in vitro and in vivo pharmacokinetic properties. In vivo experiments using labeled macrophages and paw thickness measurements confirmed compound 11’s potential to reduce macrophage infiltration and alleviate inflammation. These findings highlight compound 11 as a potent and promising therapeutic candidate for the treatment of acute inflammatory diseases and warrant further investigation to explore various biological roles.

Sodium butyrate alleviates lipopolysaccharide-induced inflammation through JAK/STAT signalling in primary human corneal fibroblasts

BackgroundBacterial keratitis is a common cause of blindness. Antibiotic treatment leads to the rapid release of lipopolysaccharide (LPS), which can activate corneal fibroblasts and cause persistent and excessive inflammatory responses. The anti-inflammatory drugs currently used to treat keratitis have serious side effects. Therefore, the ability of sodium butyrate (NaB), which can suppress the production of proinflammatory cytokines and promote the production of anti-inflammatory cytokines, to ameliorate keratitis was assessed in the present study. MethodsThe effect of NaB on the viability of primary human corneal fibroblasts was assayed with a CCK-8 kit. Cell migration was assessed by an in vitro scratch assay. Cell phenotypes were assessed by Western blotting and immunofluorescence staining. An antibody array was used to measure the production of proinflammatory cytokines and chemokines. ResultsAt 0–1 mM, NaB had no significant effect on cell viability, promoted the expression of the keratocyte marker keratocan and inhibited the fibroblast marker vimentin. Inhibition of cell migration was observed in the wound healing assay. By targeting the Janus kinase/signal transducer and activator of transcription (JAK/STAT) signalling pathway, NaB decreased the levels of inflammation-related cytokines and chemokines whose expression was induced by LPS. ConclusionsNaB maintained the keratocyte phenotype, inhibited cell migration, and relieved LPS-induced inflammatory responses through the JAK/STAT signalling pathway.

A novel amphiphilic squalene-based compound with open-chain polyethers reduces malignant melanoma metastasis in-vitro and in-vivo

Squalene (SQ) is a well-known antioxidant and anti-inflammatory agent that provides promising anti-aging and UV-protective roles on human skin. However, its strong hydrophobic nature, accompanied by issues such as poor solubility and limited tissue permeation, has created challenges for scientists to investigate its untapped potential in more complex conditions, including cancer progression. The present study assessed the potent anti-metastatic properties of a newly synthesized amphiphilic ethylene glycol SQ derivative (SQ-diEG) in melanoma, the most fatal skin cancer. In vitro and in vivo experiments have discovered that SQ-diEG may exert its potential on melanoma malignancy through the mitochondria-mediated caspase activation apoptotic signaling pathway. The potent anti-metastatic effect of SQ-diEG was observed in vitro using highly proliferative and aggressive melanoma cells. Administration of SQ-diEG (25 mg/kg) significantly decreased the tumor burden on the lung and inhibited the metastasis-associated proteins and gene markers in B16F10 lung colonization mice model. Furthermore, global gene profiling also revealed a promising role of SQ-diEG in tumor microenvironment. We anticipated that the amphiphilic nature of the SQ compound bearing ethylene glycol oligomers could potentially augment its ability to reach the pathology site, thus enhancing its therapeutic potential in melanoma.

Efficacy of Intra-articular Platelet-rich Plasma versus Hydrocortisone with Local Anaesthetic Injection in Temporomandibular Joint Disorders - A Prospective Study

Abstract Introduction: Temporomandibular joint (TMJ) is subjected to many disorders commonly termed temporomandibular disorders (TMDs) which include TMJ hypermobility, ankylosis and internal derangement. In the past, many non-invasive conservative treatment modalities were tried out for their treatment which include joint unloading, the use of anti-inflammatory agents and physiotherapy. In recent times, injections of corticosteroids and platelet-rich plasma (PRP) into the TMJ have been proposed as alternative therapeutic methods. The main objective of the prospective study was to compare the efficacy of intra-articular injection of PRP and hydrocortisone with local anaesthetic agents in reducing the symptoms in patients with TMDs. Materials and Methods: This prospective study included 30 patients with TMDs, out of which 15 patients (Group I) received PRP injections and 15 patients (Group II) received hydrocortisone with local anaesthetics for arthrocentesis in their affected joints. The patients were assessed for pain, maximum interincisal mouth opening, TMJ sound and disc displacement. Results: The pain was markedly reduced in patients who received PRP injections (Group I) as compared to those who received hydrocortisone injection (Group II). An increase in mouth opening was similar in both the groups, and TMJ sounds were reduced in patients who received PRP. Magnetic resonance imaging also showed that PRP-treated patients showed better articular disc repair than patients treated with hydrocortisone. Discussion: PRP increases chondrocyte proliferation and production of matrix molecules and helps maintain the integrity of the chondral surface, thereby facilitating joint movement, whereas corticosteroids are more potent anti-inflammatory agents and they act by inhibiting prostaglandin synthesis which is the mediator of inflammation. Thus, the use of PRP has been proven to show better results in reducing the symptoms of TMDs and also helped in articular disc repair.

Anti-inflammatory effects of Gingerenone A through modulation of toll-like receptor signaling pathways

Toll-like receptors (TLRs) play a pivotal role in initiating immune responses, particularly in the context of inflammation. However, an excessive inflammation can detrimentally affect the immune homeostasis Thus, it is important to regulate TLR signaling pathways appropriately. Gingerenone A (GIA), a bioactive compound derived from ginger, has garnered significant attention due to its potential anti-inflammatory properties. In this study, we investigate modulatory effects of GIA on TLR signaling pathways. Results showed that GIA effectively suppressed TLR-mediated inflammatory responses by modulating key signaling molecules such as nuclear factor kappa B and interferon regulatory factor 3. These results indicate that GIA is a novel regulator of TLR signaling, offering promising avenues for the development of new anti-inflammatory agents.

Purulent pericarditis and cardiac tamponade in HIV: a case report on a dreaded complication of streptococcus pneumoniae

Introduction and importance: Purulent pericarditis is an uncommon complication of Streptococcus pneumoniae, which commonly occurs in an immunocompromised state such as HIV and can lead to life-threatening complications such as cardiac tamponade and potentially death if untreated. Early identification, pericardiocentesis, and general measures such as antibiotics and anti-inflammatory medications can be life-saving. Case presentation: We present a case of a 64-year-old male with HIV who presented with clinical symptoms suggestive of pericarditis. Chest imaging revealed multifocal airspace diseases and moderate pericardial effusion. He had worsening lactic acidosis, and bedside point-of-care ultrasound showed pericardial effusion with features suggestive of cardiac tamponade. His lactic acidosis improved with emergency pericardiocentesis. Blood and pericardial fluid cultures revealed Streptococcus pneumoniae. He was further treated with intravenous antibiotics, colchicine, and ibuprofen. Clinical discussion: Although Streptococcus pneumoniae is a common etiology of community-acquired pneumonia (CAP), it has not been cited as the leading cause of pericarditis or pericardial effusion. In immunocompromised patients, it is necessary to consider a broad differential diagnosis as an etiology of acute chest pain, as it may be challenging to differentiate pleuritic and pericarditic chest pain from clinical presentation only. Moreover, infectious etiology of acute pericarditis and pericardial effusion should be considered in this patient population, especially those with HIV. At the same time, it is crucial to promptly identify and treat cardiac tamponade to prevent further deterioration. Conclusion: Our case provides insight into the diagnosis and management of CAP and its potential complication of purulent pericarditis and cardiac tamponade in immunocompromised patients.

Exploring the Anti-Inflammatory and Antioxidative Potential of Selenium Nanoparticles Biosynthesized by Lactobacillus casei 393 on an Inflamed Caco-2 Cell Line.

Selenium (Se) plays a crucial role in modulating inflammation and oxidative stress within the human system. Biogenic selenium nanoparticles (SeNPs) synthesized by Lactobacillus casei (L. casei) exhibit anti-inflammatory and anti-oxidative properties, positioning them as a promising alternative to traditional supplements characterized by limited bioavailability. With this context in mind, this study investigates the impact of selenium and L. casei in ameliorating inflammation and oxidative stress using a cell line model. The study is centered on the biosynthesis of selenium nanoparticles (SeNPs) by L. casei 393 under anaerobic conditions using a solution of sodium selenite (Na2SeO3) in the bacterial culture medium. The generation of SeNPs ensued from the interaction of L. casei bacteria with selenium ions, a process characterized via transmission electron microscopy (TEM) to confirm the synthesis of SeNPs. To induce inflammation, the human colonic adenocarcinoma cell line, Caco-2 was subjected to interleukin-1 beta (IL-1β) at concentrations of 0.5 and 25 ng/ml. Subsequent analyses encompass the evaluation of SeNPs derived from L. casei, its supernatant, commercial selenium, and L. casei probiotic on Caco2 cell line. Finally, we assessed the inflammatory and oxidative stress markers. The assessment of inflammation involved the quantification of NF-κB and TGF-β gene expression levels, while oxidative stress was evaluated through the measurement of Nrf2, Keap1, NOX1, and SOD2 gene levels. L. casei successfully produced SeNPs, as confirmed by the color change in the culture medium and TEM analysis showing their uniform distribution within the bacteria. In the inflamed Caco-2 cell line, the NF-κB gene was upregulated, but treatment with L. casei-SeNPs and selenium increased TGF-β expression. Moreover, L. casei-SeNPs upregulated SOD2 and Nrf2 genes, while downregulating NOX1, Keap1, and NF-κB genes. These results demonstrated the potential of L. casei-SeNPs for reducing inflammation and managing oxidative stress in the Caco-2 cell line. The study underscores the ability of L. casei-SeNPs to reduce oxidative stress and inflammation in inflamed Caco-2 cell lines, emphasizing the effectiveness of L. casei as a source of selenium. These insights hold significant promise for the development of SeNPs derived from L. casei as potent anti-inflammatory and anti-cancer agents, paving the way for novel therapeutic applications in the field.

Biological activities of derived pigments and polyphenols from the newly recorded alga Phyllymenia gibbesii

The newly recorded Phyllymenia gibesii in the Mediterranean Sea at Alexandria coast of Egypt is regarded as a significant source of bioactive substances and is applied as an antioxidant, anti-inflammatory, and antimicrobial agent. According to the HPLC chromatograms, the acetone extract of P. gibesii comprised ten photosynthetic pigments (chlorophyll-a, chlorophyll-d, α-carotene, β-carotene, phycocyanin, allophycocyanin, antheraxanthin, β-cryptoxanthin, lutein, and violaxanthin). Total carotenoids were the dominant class in the pigments’ profile, achieving a concentration of 257 g/g dry weight. The P. gibbesii extract had a total content of phenols (146.67 mg/g) and a total content of flavonoids (104.40 mg/g). The capacity of all the investigated biological activities augmented with the concentration of the algal extract. The maximal DPPH scavenging capacity was 81.44%, with an inhibitory concentration (IC50) of 9.88 μg/mL. Additionally, the highest ABTS scavenging capacity was 89.62%, recording an IC50 of 21.77 μg/mL. The hemolytic activity of P. gibbesii attained a maximum capacity of 49.88% with an IC50 of 100.25 μg/mL. Data also showed the maximum anti-inflammatory effectiveness at 81.25%, with an IC50 of 99.75 μg/mL. Furthermore, the extract exhibited antimicrobial capacity against all reference strains, particularly at high concentrations (0.1 mg/mL), with the greatest effect on C. albicans and E. coli.

Treatment of spondyloarthritis with disease-modifying anti-rheumatic drugs during pregnancy and breastfeeding: comparing the recommendations and guidelines of the principal societies of rheumatology.

This paper aims to provide an overview of the use of treatments available for axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) during pregnancy and breastfeeding, according to current national recommendations and international guidelines, as well as data on the impact on pregnancy outcomes of paternal exposure to treatment. We performed a narrative review of national and international recommendations and guidelines on the reproductive health of patients suffering from rheumatic diseases. The last updated recommendations and guidelines were considered source data. We reported updated information regarding the treatment of axSpA and PsA with nonsteroidal anti-inflammatory drugs, intra-articular glucocorticoids, conventional synthetic disease-modifying antirheumatic drugs (DMARDs), biologic DMARDs, and targeted synthetic DMARDs during the preconception period, pregnancy, and breastfeeding, as well as data related to paternal exposure. We highlighted any medications that should be discontinued and/or not used in the reproductive age group and also treatments that may be continued, avoiding the withdrawal of drugs that can be used in the different phases, thus preventing the risk of increasing disease activity and flares before, during, and after pregnancy in SpA patients. The best management of pregnancy in patients with SpA is based on knowledge of updated drug recommendations, a careful and wise evaluation of the risks/benefits of starting or continuing treatment from the SpA diagnosis in a woman of childbearing age through pregnancy and lactation, and sharing therapeutic choices with other healthcare providers (in particular, gynecologists/obstetricians) and the patient.

Response of crop seed germination and primary root elongation to a binary mixture of diclofenac and naproxen.

Non-steroidal anti-inflammatory drugs, diclofenac (DCF) and naproxen (NPX), represent a group of environmental contaminants often detected in various water and soil samples. This work aimed to assess possible phytotoxic effects of DCF and NPX in concentrations 0.1, 1 and 10 mg/L, both individually and in binary mixtures, on the seed germination and primary root elongation of crops, monocots Allium porrum and Zea mays, and dicots Lactuca sativa and Pisum sativum. Results proved that the seed germination was affected by neither individual drugs nor their mixture. The response of primary root length in monocot and dicot species to the same treatment was different. The Inhibition index (%) comparing the root length of drug-treated plants to controls proved to be approximately 10% inhibition in the case of dicots lettuce and pea, and nearly 20% inhibition in monocot leek, but almost 20% stimulation in monocot maize. Assessment of the binary mixture effect confirmed neither synergistic nor antagonistic interaction of DCF and NPX on early plant development in the applied concentration range.
