[PMID: 38799700 PMCID: PMC11128233 DOI: 10.2147/ijn.s458907] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Accepted: 04/15/2024] [Indexed: 05/29/2024] Open
Abstract
Cannabinoids are compounds found in and derived from the Cannabis plants that have become increasingly recognised as significant modulating factors of physiological mechanisms and inflammatory reactions of the organism, thus inevitably affecting maintenance of homeostasis. Medical Cannabis popularity has surged since its legal regulation growing around the world. Numerous promising discoveries bring more data on cannabinoids' pharmacological characteristics and therapeutic applications. Given the current surge in interest in the medical use of cannabinoids, there is an urgent need for an effective method of their administration. Surpassing low bioavailability, low water solubility, and instability became an important milestone in the advancement of cannabinoids in pharmaceutical applications. The numerous uses of cannabinoids in clinical practice remain restricted by limited administration alternatives, but there is hope when biodegradable polymers are taken into account. The primary objective of this review is to highlight the wide range of indications for which cannabinoids may be used, as well as the polymeric carriers that enhance their effectiveness. The current review described a wide range of therapeutic applications of cannabinoids, including pain management, neurological and sleep disorders, anxiety, and cancer treatment. The use of these compounds was further examined in the area of dermatology and cosmetology. Finally, with the use of biodegradable polymer-based drug delivery systems (DDSs), it was demonstrated that cannabinoids can be delivered specifically to the intended site while also improving the drug's physicochemical properties, emphasizing their utility. Nevertheless, additional clinical trials on novel cannabinoids' formulations are required, as their full spectrum therapeutical potential is yet to be unravelled.

de Morais SV, Calado GP, Carvalho RC, Garcia JBS, de Queiroz TM, Cantanhede Filho AJ, Lopes AJO, Cartágenes MDSDS, Domingues GRDS. Impact of Cuminaldehyde and Indomethacin Co-Administration on Inflammatory Responses in MIA-Induced Osteoarthritis in Rats. Pharmaceuticals (Basel) 2024; 17:630. [PMID: 38794200 PMCID: PMC11125240 DOI: 10.3390/ph17050630] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2024] [Revised: 05/06/2024] [Accepted: 05/09/2024] [Indexed: 05/26/2024] Open
Abstract
Osteoarthritis (OA) remains a chronic incurable condition, presenting substantial challenges in treatment. This study explores a novel strategy by investigating the concurrent use of cuminaldehyde, a natural compound, with indomethacin in animal models of MIA-induced OA. Our results demonstrate that the co-administration of cuminaldehyde and indomethacin does indeed produce a superior effect when compared to these compounds individually, significantly enhancing therapeutic outcomes. This effect is evidenced by a marked reduction in pro-inflammatory cytokines IL-6 and IFN-γ, alongside a significant increase in the anti-inflammatory cytokine IL-10, compared to treatments with each compound alone. Radiographic analyses further confirm the preservation of joint integrity and a reduction in osteoarthritic damage, highlighting the association's efficacy in cartilage-reducing damage. These findings suggests that the association of cuminaldehyde and indomethacin not only slows OA progression but also offers enhanced cartilage-reducing damage and fosters the production of protective cytokines. This study underscores the potential benefits of integrating natural products with pharmaceuticals in OA management and stresses the importance of further research to fully understand the mechanisms underlying the observed potentiated effects.

Abstract
Objectives Randomized clinical trials are used to evaluate the efficacy of various pain treatments individually, while a limited number of observational studies have portrayed the overall relief experienced by persons living with chronic pain. This study aimed to describe pain relief in real-world clinical settings and to identify associated factors. Methods This exploratory web-based cross-sectional study used data from 1,419 persons recruited in the community. Overall pain relief brought by treatments used by participants was assessed using a 0%-100% scale (10-unit increments). Results A total of 18.2% of participants reported minimal pain relief (0%-20%), 60.0% moderate to substantial pain relief (30%-60%), and 21.8% extensive pain relief (70%-100%). Multivariable multinomial regression analysis revealed factors significantly associated with greater pain relief, including reporting a stressful event as circumstances surrounding the onset of pain, living with pain for ≥10 years, milder pain intensity, less catastrophic thinking, use of prescribed pain medications, use of nonpharmacological pain treatments, access to a trusted healthcare professional, higher general health scores, and polypharmacy. Factors associated with lower pain relief included surgery as circumstances surrounding pain onset, use of over-the-counter pain medications, and severe psychological distress. Discussion In this community sample of persons living with chronic pain, 8 out of 10 persons reported experiencing at least moderate relief with their treatment. The analysis has enabled us to explore potential modifiable factors as opportunities for improving the well-being of persons living with chronic pain.

Abstract
Background Pain perception and management vary across cultural contexts; yet, little is known about pain approaches in the general population of Palestine. Existing research lacks specific knowledge about how pain is coped with in this region. Objective To explore pain management among Palestine's general population, studying prevalence, characteristics, and sociodemographic influences. It aims to uncover treatment choices and understand cultural impacts on pain experiences, offering insights into Palestinian pain perception and coping strategies. Methods Convenience and snowball sampling methods were employed to collect data from 646 adults in Palestine. Participants' sociodemographic characteristics, pain experiences, and pain management strategies were examined. Descriptive statistics, chi-square tests, and binary logistic regression followed by multiple logistic regressions were used for data analysis. Results A significant portion of participants reported experiencing pain, with chronic pain being predominant. Pain prevalence varied across age groups, with higher rates in the elderly, followed by middle-aged and younger participants. Marital status and education level were linked to pain prevalence. Participants employed diverse pain management strategies, such as self-medication, physician visits, complementary medicine, and physical therapy. Age, gender, marital status, and education level influenced choices in pain management approaches. For instance, the elderly favored traditional medical interventions, while higher education levels were associated with reduced inclination toward conventional treatments. Conclusion This study underscores the complex interaction of sociodemographic factors, pain experiences, and treatment preferences in pain management. It emphasizes personalized strategies considering age, marital status, education, and gender. Integrating these aspects improves treatment and satisfaction. The findings empower healthcare providers to create precise strategies, enhancing patient experiences for better outcomes.

Abstract
Background Patients are increasingly utilizing the internet to learn about dietary and herbal supplements (DHSs) for various diseases/conditions, including pain management. Online health information has been found to be inconsistent and of poor quality in prior studies, which may have detrimental effects on patient health. This study assessed the quality of online DHSs consumer health information for pain. Methods Six search items related to DHSs and pain were used to generate the first 20 websites on Google across four English-speaking countries. The identified 480 webpages produced 68 eligible websites, which were then evaluated using the DISCERN tool. The mean scores and standard deviations (SD) of the reviewers' ratings on each of the 15 DISCERN instrument items as well as the overall total score were calculated. Results The mean summed score for the 68 eligible websites was 46.6 (SD = 10.1), and the mean overall rating was 3.3 (SD = 0.8). Websites lacked information regarding areas of uncertainty, the effects of no treatment being used, and how treatments affect the overall quality of life. These shortcomings were especially apparent across commercial websites, which frequently displayed bias, failed to report the risks of DHS products, and lacked support for shared decision-making regarding the use of DHSs. Conclusion Variability exists in the quality of online consumer health information regarding DHS use for pain. Healthcare providers should be aware of and provide guidance to patients regarding the identification of reliable online resources so that they can make informed decisions about DHS use for pain management.

Potential anxiolytic and antidepressant-like effects of luteolin in a chronic constriction injury rat model of neuropathic pain: Role of oxidative stress, neurotrophins, and inflammatory factors. Int Immunopharmacol 2023; 122:110520. [PMID: 37478667 DOI: 10.1016/j.intimp.2023.110520] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 06/07/2023] [Accepted: 06/13/2023] [Indexed: 07/23/2023]
Abstract
This study aimed to examine the effects of luteolin (LUT) on chronic neuropathic pain (NP)-induced mood disorders (i.e., anxiety and depression) by regulating oxidative stress, neurotrophic factors (NFs), and neuroinflammation. Chronic constrictive injury (CCI) was used to induce NP in the animals. Animals in the treatment groups received LUT in three doses of 10, 25, and 50 mg/kg for 21 days. The severity of pain and mood disorders were examined. Finally, animals were sacrificed, and their brain tissue was used for molecular and histopathological studies. CCI led to cold allodynia and thermal hyperalgesia. Mood alterations were proven in the CCI group, according to the behavioral tests. Levels of glial cell-derived neurotrophic factor (GDNF), brain-derived neurotrophic factor (BDNF), B-cell lymphoma-2 (Bcl2), superoxide dismutase (SOD), catalase (CAT), and nuclear factor erythroid-2-related factor 2 (Nrf2) were reduced in the hippocampus (HPC) and prefrontal cortex (PFC). Furthermore, the levels of MDA, Bcl-2-associated X protein (Bax), and inflammatory markers, including nuclear factor kappa B (NF-κB), NLR family pyrin domain containing 3 (NLRP3), interleukin-1β (IL-1β), IL-18, IL-6, and tumor necrosis factor-α (TNF-α) significantly increased in the HPC and PFC following CCI induction. LUT treatment reversed the behavioral alterations via regulation of oxidative stress, neurotrophines, and inflammatory mediators in the HPC and PFC. Findings confirmed the potency of LUT in the improvement of chronic pain-induced anxiety- and depressive-like symptoms, probably through antioxidant, anti-inflammatory, and neuroprotective properties in the HPC and PFC.

Abstract
BACKGROUND There is increasing use of complementary and alternative medicines (CAMs) alone or as an adjuvant therapy to conventional medicines in osteoarthritis (OA) patients. OBJECTIVES This study aimed to describe the prevalence and correlates of the use of CAMs among community-dwelling older adults. METHODS Data from the Tasmania Older Adult Cohort Study (TASOAC, n = 1099) were used to describe the prevalence of CAM use. Correlates of CAM use were assessed by comparing CAM users and non-users. To further assess correlates of CAM use, participants with at least one joint with pain were classified into four categories: CAM-only, analgesics-only, co-therapy, and "neither CAMs nor analgesics" (NCNA). RESULTS In all, 385 (35.0%) of our participants reported use of CAMs, among which vitamins/minerals were used most (22.6%, n = 232). Compared with CAM non-users, CAM users were more likely to be female, were less likely to be overweight, were better educated, had more joints with OA, had fewer WOMAC scores, and did more steps per day. Among participants with any joint pain, the CAM-only group were less likely to be overweight, consumed more alcohol, had higher quality of life, had more steps per day, and had fewer pain-related symptoms compared with the analgesic-only group. CONCLUSION Complementary and alternative medicines were commonly used among Tasmanian older adults, with 35% of the population using CAMs either alone or in combination with conventional analgesics. CAM users were more likely to be female, be better educated, have more joints with OA, and had healthier lifestyles, including lower body mass index and higher number of steps per day.

Abstract
BACKGROUND The use of herbal medicine (HM) as a self-management practice for treating various diseases has gained popularity worldwide. Consumers co-administer herbal products with conventional medicine without the knowledge of possible herb-drug interaction (HDI). AIM This study aimed to assess patients' perception and use of HM and their knowledge of HDI. SETTING Participants attending primary health care (PHC) clinics in three provinces (Gauteng, Mpumalanga and Free State), South Africa, were recruited. METHODS Focus group discussions comprising a total of thirty (N = 30) participants were conducted using a semi-structured interview guide. Discussions were audio-recorded and then transcribed verbatim. Data were analysed using thematic content analysis. RESULTS Reasons for using HM, sources of information on HM, co-administration of HM and prescribed medicine, disclosure of the use of HM, PHC nurses' attitudes and not having time to engage were frequently discussed. Respondents' lack of knowledge and perceptions about HDI and their dissatisfaction with prescribed medicine because of experienced side effects were also discussed. CONCLUSION Because of the lack of discussions and non-disclosure about HM in PHC clinics, patients are at risk of experiencing HDIs. Primary health care providers should regularly enquire about HM use on every patient, to identify and prevent HDIs. The lack of knowledge about HDIs by patients further compromises the safety of HM.Contribution: The results highlighted the lack of knowledge of HDI by patients thus assisting the healthcare stakeholders in South Africa to implement measures to educate patients attending PHC clinics.

Abstract
Neuropathic pain is a debilitating condition characterized by abnormal signaling within the nervous system, resulting in persistent and often intense sensations of pain. It can arise from various causes, including traumatic nerve injury, neuropathy, and certain diseases. We present an overview of current and emerging pharmacotherapies for neuropathic pain, focusing on novel drug targets and potential therapeutic agents. Current pharmacotherapies, including tricyclic antidepressants, gabapentinoids, and serotonin norepinephrine re-uptake inhibitors, are discussed, as are emerging treatments, such as ambroxol, cannabidiol, and N-acetyl-L-cysteine. Additionally, the article highlights the need for further research in this field to identify new targets and develop more effective and targeted therapies for neuropathic pain management.

Srivastava S, Girandola RN. Effect of E-PR-01 on Activity-Induced Acute Knee Joint Discomfort in Healthy Individuals: A Randomized, Placebo-Controlled, Double-Blind, Cross-Over Study. J Pain Res 2023; 16:2141-2153. [PMID: 37384126 PMCID: PMC10295599 DOI: 10.2147/jpr.s412018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Accepted: 06/12/2023] [Indexed: 06/30/2023] Open
Abstract
Purpose A randomized, double-blind, placebo-controlled cross-over study was conducted to investigate the efficacy and safety of E-PR-01, a proprietary formula containing Vitex negundo and Zingiber officinale, on knee joint discomfort due to pain. Patients and Methods Forty adults aged 20-60 years with self-reported pain score of ≤30 mm at rest and ≥60 mm post-exertion on a 100-mm visual analog scale (VAS) were randomized in a 1:1 ratio to receive either the E-PR-01 (200 mg twice daily) or placebo for 5 days. The primary outcome was time to achieve meaningful pain relief (MPR) (≥40% reduction in post-exertion pain VAS score from baseline) post-single dose of intervention on day 1 compared to placebo. The secondary outcomes were post-exertion pain intensity difference (PID) at 2-, 3- and 4-hours and time-weighted sum of pain intensity difference (SPID) over 4 hours post single dose on day 1; post-exertion VAS score at 4 hours' post-intervention on day 5; percentage of responders on day 1; and physical efficiency as assessed by the total duration of exercise sessions completed after single dose of IP compared to placebo. Results The average time to achieve MPR was 3.38 hours, 32.50% of participants achieved it in the E-PR-01 group post single-dose administration on day 1 as opposed to the placebo where no participant achieved MPR. There were significant intergroup differences in PID (-23.58 vs 2.45 mm) and SPID (-67.48 vs -0.08 mm) at 4 hours of E-PR-01 and placebo administration on day 1. 95% of participants in the IP group experienced some degree of pain relief within 2 hours compared to 37.5% in the placebo group. Conclusion A single dose of E-PR-01 provided a statistically significant as well as clinically meaningful reduction in exercise-induced knee joint discomfort within 4 hours of administration.

Abstract
Β-sitosterol is a phytosterol, documented to possess various activities including protection against inflammation, diabetes and Alzheimer's disease. The current investigation was designed to explore the analgesic potential of β-sitosterol and the possible molecular mechanism involved in the observed effect. β-sitosterol was administered at varying doses of 10, 20, and 40 mg/kg before subjecting the mice to acetic acid and formalin challenges. The number of writhings in acetic acid and the number of flinchings and foot tappings were quantified in the formalin test. For mechanistic studies, substance P (cyclooxygenase-2 (COX-2) stimulator) and L-Nitro arginine methyl ester (L-NAME) (nitric oxide synthetases (NOS) inhibitor) and L-arginine (nitric oxide precursor) were administered before β-sitosterol treatment. β-sitosterol (10, 20, 40 mg/kg) treatment significantly reduced acetic acid-induced writhings and ameliorated the formalin-induced inflammatory phase dose-dependently. Whereas, 40 mg/kg dose of β-sitosterol abrogated the formalin-induced neurogenic phase. Substance-P abrogated the effect of β-sitosterol in both neurogenic and inflammatory phases. Whereas, L-arginine only abrogated the inflammatory phase. In biochemical analysis, β-sitosterol treatment reduced the level of interleukin-6 (IL-6), thiobarbituric acid reactive substances (TBARS) and increased the level of reduced glutathione (GSH). Furthermore, L-arginine and substance-P abrogated the GSH increasing and TBARS lowering effect of β-sitosterol (40 mg/kg). Overall, the current study delineated that β-sitosterol may induce an anti-nociceptive effect via inhibiting the IL-6, oxidative stress, cyclo-oxygenase and nitric oxide.

Abstract
BACKGROUND AND OBJECTIVES Safe and effective management of cancer-related pain is a worldwide challenge. In the search for treatment options, natural products used in Chinese herbal medicines (CHMs) have received attention in clinical studies for their effects on cancer-related pain. The objective of this systematic review is to evaluate the clinical evidence for topically applied CHMs as adjunctive treatments for cancer pain management. METHODS Nine biomedical databases and 4 clinical trial registries were searched for randomized-controlled trials (RCTs) that reported measures of pain and/or quality of life. Risk of bias was assessed using the Cochrane tool. Meta-analysis employed mean difference (MD) with 95% confidence intervals (random effects). RESULTS Twenty (20) RCTs (1636 participants) met the inclusion criteria. Meta-analyses were grouped based on the comparisons and outcome measures. For pain intensity, there was a greater reduction in the topical CHM group versus placebo (MD -0.72 [-1.04, -0.40]), no difference when compared to tramadol (MD -0.15 [-0.38, 0.08]), and a greater reduction when topical CHMs were combined with conventional analgesic medications (MD -0.67 [-0.93, -0.40]). Analgesic onset time was reduced in the CHM group compared to tramadol (MD -26.02 [-27.57, -24.47] minutes), and for CHMs combined with conventional medications (MD -19.17 [-21.83, -16.52] minutes). When CHMs were combined with analgesic medications, improvements were found for duration of analgesia (MD 1.65 [0.78, 2.51] hours), analgesic maintenance dose (MD -31.72 [-50.43, -13.01] milligrams/day), and quality of life. CONCLUSION Addition of topical CHMs to conventional analgesic medications was associated with improved outcomes for pain intensity, some other pain-related outcomes, and measures of quality of life. Limitations included methodological issues in some studies and considerable heterogeneity in some pooled results.

A Protocol for a Single-Centered, Pragmatic, Randomized, Controlled, Parallel Trial Comparing Comprehensive Nonsurgical Therapy Options for Individuals with Lumbar Spinal Stenosis. J Pain Res 2023; 16:773-784. [PMID: 36923649 PMCID: PMC10010744 DOI: 10.2147/jpr.s398897] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2022] [Accepted: 02/20/2023] [Indexed: 03/11/2023] Open
Abstract
Aim Lumbar spinal stenosis (LSS) is a long-term degenerative disease. Considering the risks and advantages of the patient's age range and the characteristics of the condition, non-surgical treatment is recommended. To determine the best first-line non-surgical therapy for LSS, few studies have examined different non-surgical therapies. Therefore, the main objective of this study is to determine whether the selection of comprehensive Chinese medicine (CM) treatment for LSS is more successful than non-surgical conservative treatment. Patients and Methods In this two-armed, parallel, single-centered, pragmatic randomized controlled study, 94 LSS participants will be randomized to receive 24 sessions of comprehensive CM therapy or conservative treatment for 3 months, with follow-up assessments at 6, 9, 12, and 15 months. The primary outcome will be based on the success rate of the Zurich Claudication Questionnaire (ZCQ) for the most clinical important difference (MCID) at 3 and 15 months. Secondary outcomes include Numerical Rating Scale (NRS) scores for back and leg pain, ZCQ scores, Oswestry Disability Index scores for lumbar dysfunction, and Short-Form 12 scores for health-related quality of life at 3, 6, 9, 12, and 15 months. Adverse events and incidences of surgery will be reported anytime during the trial and follow-up. Conclusion This protocol examines the comparative efficacy of comprehensive CM therapy compared with conventional care through a pragmatic randomized controlled trial to present data to facilitate clinical or policy decision-making. The outcomes will make it easier to decide which patient-centered treatments to prioritize for LSS.

Natural remedies medicine derived from flaxseed (secoisolariciresinol diglucoside, lignans, and α-linolenic acid) improve network targeting efficiency of diabetic heart conditions based on computational chemistry techniques and pharmacophore modeling. J Food Biochem 2022; 46:e14480. [PMID: 36239429 DOI: 10.1111/jfbc.14480] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 08/31/2022] [Accepted: 09/29/2022] [Indexed: 01/14/2023]
Abstract
Cytokine storms lead to cardiovascular diseases (CVDs). Natural herbal compounds are considered the primary source of active agents with the potential to prevent or treat inflammatory-related pathologies such as CVD and diabetes. Flaxseed contains phytochemicals, including secoisolariciresinol diglucoside (SDG), α-linolenic acid (ALA), and lignans, termed "SAL." Hence, we evaluated the effect of the SAL on the H9c2 cardiac cells in hyperlipidemic and hyperglycemic conditions. Here, candidate hub genes, TNF-α, IL6, SIRT1, NRF1, NPPA, and FGF7, were selected as effective genes in diabetic cardiovascular pathogenesis based on in-silico analysis and chemoinformatic. Myocardial infarction (MI) was induced using H9c2 cardiac cells in hyperlipidemic and hyperglycemic conditions. Real-time qPCR was conducted to assess the expression level of hub genes. This study indicated that SAL compounds bound to the Il-6, SIRT1, and TNF-α active sites as druggable candidate proteins based on the chemoinformatics analysis. This study displayed that the TNF-α, IL6, SIRT1, NRF1, NPPA, and FGF7 network dysfunction in MI models were ameliorated by SAL consumption. Furthermore, SAL compounds improved the function and myogenesis of H9c2 cells in hyperlipidemic and hyperglycemic conditions. Our data suggested that phytochemicals obtained from flaxseed might have proposed potential complementary treatment or preventive strategies for MI. PRACTICAL APPLICATIONS: Phytochemicals obtained from flaxseed (SAL) could reverse diabetic heart dysfunction hallmarks and provide new potential treatment approaches in cardiovascular therapy. SAL could be considered complementary and alternative medicines for treating various disorders/diseases singly or synchronizing with prescription drugs.

Abstract
Pain is the predominant symptom of many clinical diseases and is frequently associated with neurological and musculoskeletal problems. Chronic pain is frequent in the elderly, causing suffering, disability, social isolation, and increased healthcare expenses. Chronic pain medication is often ineffective and has many side effects. Nonsteroidal over-the-counter and prescription drugs are frequently recommended as first-line therapies for pain control; however, long-term safety issues must not be neglected. Herbs and nutritional supplements may be a safer and more effective alternative to nonsteroidal pharmaceuticals for pain management, especially when used long-term. Recently, topical analgesic therapies have gained attention as an innovative approach due to their sufficient efficacy and comparatively fewer systemic side effects and drug-drug interactions. In this paper, we overview the main natural herbal pain relievers, their efficacy and safety, and their potential use as topical agents for pain control. Although herbal-derived medications are not appropriate for providing quick relief for acute pain problems, they could be used as potent alternative remedies in managing chronic persistent pain with minimal side effects.

Abstract
Cardiovascular diseases (CVDs) are the leading cause of mortality worldwide and, together with associated risk factors such as diabetes, hypertension, and dyslipidaemia, greatly impact patients' quality of life and health care systems. This burden can be alleviated by fomenting lifestyle modifications and/or resorting to pharmacological approaches. However, due to several side effects, current therapies show low patient compliance, thus compromising their efficacy and enforcing the need to develop more amenable preventive/therapeutic strategies. In this scenario, medicinal and aromatic plants are a potential source of new effective agents. Specifically, plants from the Allioideae subfamily (formerly Alliaceae family), particularly those from the genus Allium and Tulbaghia, have been extensively used in traditional medicine for the management of several CVDs and associated risk factors, mainly due to the presence of sulphur-containing compounds. Bearing in mind this potential, the present review aims to gather information on traditional uses ascribed to these genera and provide an updated compilation of in vitro and in vivo studies validating these claims as well as clinical trials carried out in the context of CVDs. Furthermore, the effect of isolated sulphur-containing compounds is presented, and whenever possible, the relation between composition and activity and the mechanisms underlying the beneficial effects are pointed out.

Abstract
Conflicting evidence exists concerning the effects of nutrient intake in osteoarthritis (OA). A systematic literature review and meta-analysis were performed using PubMed, EMBASE, and Cochrane Library up to November 2021 to assess the effects of nutrients on pain, stiffness, function, quality of life, and inflammation markers. We obtained 52 references including 50 on knee OA. Twelve studies compared 724 curcumin patients and 714 controls. Using the standardized mean difference, improvement was significant with regard to pain and function in the curcumin group compared to placebo, but not with active treatment (i.e., nonsteroidal anti-inflammatory drugs, chondroitin, or paracetamol). Three studies assessed the effects of ginger on OA symptoms in 166 patients compared to 164 placebo controls. Pain was the only clinical parameter that significantly decreased. Vitamin D supplementation caused a significant decrease in pain and function. Omega-3 and vitamin E caused no changes in OA parameters. Herbal formulations effects were significant only for stiffness compared to placebo, but not with active treatment. A significant decrease in inflammatory markers was found, especially with ginger. Thus, curcumin and ginger supplementation can have a favorable impact on knee OA symptoms. Other studies are needed to better assess the effects of omega-3 and vitamin D.

Abstract
The research article aimed to examine the antioxidant nature of freeze–dried extracts from Urtica dioica L. and Mentha piperita L. and to present a deep characterization of their influence on the properties of natural rubber–based vulcanizates before and after simulated aging processes. Natural extracts were prepared in three solvent systems at selected volume ratios: water (100), methanol–water (50/50), ethanol–water (50/50), which were further lyophilized and used as additive to natural rubber mixtures. Freeze–dried materials were investigated by UV–VIS diffuse reflectance spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), thermal stability by thermogravimetric analysis (TGA). Antioxidant activity and total phenolic content (TPC) were also examined. Prepared samples were subjected to accelerated simulated degradation processes by using ultraviolet and thermo-oxidative aging. Vulcanizates resistance to degradation effects was determined by the study of cross-linking density (equilibrium swelling method), mechanical properties (tensile strength, elongation at break) and color change in comparison with the results of the reference samples. The research showed that analyzed extracts are characterized by a high content of polyphenols and antioxidant activity, thus have a protective influence on elastomer vulcanizates against damaging effects of aging processes, which consequently extends the lifetime of materials.

ETHNOPHARMACOLOGICAL RELEVANCE Zanthoxylum armatum DC is a traditional medicinal plant. It is widely used in clinical treatment and disease prevention in China, India and other regions. Modern studies have reported the phytotoxicity, cytotoxicity and the animal toxicity of Zanthoxylum armatum DC, and the damage of genetic material has been observed in plants, but the detailed mechanism has not been explored. Besides, the toxicity of normal mammalian cells has not been evaluated. AIM OF THE STUDY To evaluate the effects and underlying mechanism of genetic material damage in BRL 3A cells induced by Zanthoxylum armatum DC. MATERIALS AND METHODS Ultra-High Performance Liquid Chromatography and Orbitrap High-Resolution Mass Spectrometry was used for identification of compounds in methanol extract of Zanthoxylum armatum DC. BRL 3A cells were incubated with different concentrations of methanol extract of Zanthoxylum armatum DC (24 h). The cytotoxicity of extract was assessed with cell viability, LDH release rate, and ROS production. The damage of genetic material was assessed with OTM value of comet cells, cell cycle and the expression levels of p-ATM, p- Chk2, Cdc25A, and CDK2. RESULTS Ultra-High Performance Liquid Chromatography and Orbitrap High-Resolution Mass Spectrometry investigation revealed the presence of compounds belonging to flavonoid, fatty acid and alkaloid groups. The viability of BRL 3A cells was reduced in a time-dose dependent manner treated by methanol extract of Zanthoxylum armatum DC. It increased LDH release rate and ROS production, activated the DNA double strand damage marker of γH2AX and produced comet cells. In addition, methanol extract of Zanthoxylum armatum DC caused ATM-mediated DNA damage, further phosphorylated Chk2, inhibited cell cycle related proteins, and arrested the G1/S cycle. CONCLUSIONS Methanol extract of Zanthoxylum armatum DC induces DNA damage and further leads G1/S cell cycle arrest by triggering oxidative stress in the BRL 3A cells. This study provides some useful evidences for its development as an antitumor drug via activation of ATM/Chk2.

Abstract
Objectives To assess the use of complementary alternative medicines (CAM) in advanced cancer patients followed at home. Methods A consecutive sample of advanced cancer patients admitted to a home palliative care program was invited to participate in the study in a period of two months. Demographic characteristics, religious belief, education level, diagnosis, and socio-economic condition were recorded. Patients were asked about the use of CAM, considered to be a health-related treatment practiced outside the established health services. Information about CAM indications and those who prescribed or suggested CAM were also collected. Results Two hundred and eighty-three advanced cancer patients followed at home were surveyed. Twelve patients (4.2%) were receiving CAM. The indication and type of CAM were variable, as well as the costs. Given the low number of patients taking CAM, no further analysis was performed. Conclusion A limited number of advanced cancer patients followed at home were using CAM. Further multicenter studies with a larger sample should be performed to provide information about such therapies, also including eventual benefits.

Abstract
BACKGROUND AND OBJECTIVE Neuropathic pain remains a clinical challenge with limited effective treatments. Previous studies have found that magnolol (Mag), an ingredient existing in some herbs, showed neuroprotective effect. However, it remains unclear whether Mag can alleviate neuropathic pain. METHODS Chronic constriction injury (CCI) is used as the neuropathic pain model. Mice were randomly divided into 5 groups: Sham, CCI, CCI + 5, 10, 30 mg/kg Mag groups. Thermal and mechanical paw withdrawal threshold were performed at baseline and on the 3rd, 5th, 7th, 14th days post-surgery. Lumbar spinal cord and blood samples were collected on the 14th day. Blood lipid profile, kidney and liver functions, as well as the activation of microglia were evaluated, along with the related signal pathway examined using multiple methods including immunohistochemistry, RT-PCR and Western blot. RESULTS Mag alleviated thermal and mechanical hypersensitivity in CCI mice. CCI activated microglia and upregulated the expression of P2Y12, while Mag inhibited microglial activation, and downregulated the expression of P2Y12. Mag also blocked the activation of p38 mitogen-activated protein kinase (MAPK) and other pain-related cytokines such as IL-6, TNF-α and IL-1β. CONCLUSION The findings indicate that Mag has antinociceptive effect on neuropathic pain, probably mediated through P2Y12 receptors and p38 MAPK mediated pathways. With its relatively safe profile, Mag may be a potential therapeutic agent for neuropathic pain.
