ABSTRACT

Policy Points This study examines the impact of several world-changing events in 2020, such as the pandemic and widespread racism protests, on the US population's comfort with the use of identifiable data for public health. Before the 2020 election, there was no significant difference between Democrats and Republicans. However, African Americans exhibited a decrease in comfort that was different from other subgroups. Our findings suggest that the public remained supportive of public health data activities through the pandemic and the turmoil of 2020 election cycle relative to other data use. However, support among African Americans for public health data use experienced a unique decline compared to other demographic groups. CONTEXT: Recent legislative privacy efforts have not included special provisions for public health data use. Although past studies documented support for public health data use, several global events in 2020 have raised awareness and concern about privacy and data use. This study aims to understand whether the events of 2020 affected US privacy preferences on secondary uses of identifiable data, focusing on public health and research uses. METHODS: We deployed two online surveys-in February and November 2020-on data privacy attitudes and preferences using a choice-based-conjoint analysis. Participants received different data-use scenario pairs-varied by the type of data, user, and purpose-and selected scenarios based on their comfort. A hierarchical Bayes regression model simulated population preferences. FINDINGS: There were 1,373 responses. There was no statistically significant difference in the population's data preferences between February and November, each showing the highest comfort with population health and research data activities and the lowest with profit-driven activities. Most subgroups' data preferences were comparable with the population's preferences, except African Americans who showed significant decreases in comfort with population health and research. CONCLUSIONS: Despite world-changing events, including a pandemic, we found bipartisan public support for using identifiable data for public health and research. The decreasing support among African Americans could relate to the increased awareness of systemic racism, its harms, and persistent disparities. The US population's preferences support including legal provisions that permit public health and research data use in US laws, which are currently lacking specific public health use permissions.

ABSTRACT

BACKGROUND & AIMS: Hepatocellular carcinoma (HCC) has an increasing mortality in the United States and is a leading cause of morbidity and mortality in patients with cirrhosis. We aimed to estimate the financial burden related to HCC in a large nationally representative United States cohort. METHODS: We used the Surveillance, Epidemiology, and End Results program (SEER)-Medicare database to identify 4525 adult patients who were diagnosed with HCC between 2011 and 2015. We generated a 1:1 propensity score-matched cohort of patients with cirrhosis but no HCC as a comparator group to define incremental HCC-specific costs beyond costs related to underlying cirrhosis. Our main outcomes were patient liabilities and Medicare payments in the first year after HCC diagnosis. RESULTS: Compared with patients with cirrhosis, those with HCC had higher incremental patient liabilities (median +$7166; interquartile range, $2401-$16,099) and Medicare payments (+$50,110; interquartile range, $142,42-$136,239; P < .001 for both) in the first year after diagnosis. Patients with HCC had significantly higher inpatient, outpatient, and physician service costs compared with the matched cohort with cirrhosis (P < .001 for all). Patients with early-stage HCC had lower incremental patient liabilities (median, $4195 vs $8238; P < .001) and Medicare payments (median, $28,207 vs $59,509; P < .001) than those with larger tumor burden. In multivariable median regression analysis, incremental patient liabilities and Medicare payments were significantly associated with the National Cancer Institute comorbidity index, nonalcoholic fatty liver disease etiology, presence of ascites, and presence of hepatic encephalopathy. CONCLUSIONS: Patients with HCC suffer from cancer-related financial burden, highlighting a need for policy interventions and financial support systems.

ABSTRACT

Coriandrum sativum (coriander) is an edible herb in the family Apiaceae. The leaves, fruits, and stems of C. sativum have long been used as culinary spice due to their favorable odor. Traditional practitioners used this plant for treating different diseases like blepharitis, scabies, aphthous stomatitis, laryngitis, headache, and palpitation. In modern researches, coriander has demonstrated anxiolytic, anticonvulsant, antimigraine, neuroprotective, analgesic, diuretic, hypoglycemic, hypolipidemic, hypotensive, anticancer, and antioxidant activities. Coriander contains a wide range of bioactive phytochemicals among which phenylpropenes, terpenoids, isocoumarins, phytosterols, and fatty acids are the most important. This review provides information about the botanical and ethnobotanical aspects, chemical profile, therapeutic uses in Islamic traditional medicine (ITM), and recent pharmacological studies of coriander effects. The results have shown that coriander and its monoterpenoid compound, linalool, can be considered as potential drug candidates for treating metabolic syndrome and different inflammatory conditions especially neural and CNS diseases.

ABSTRACT

Curcumin has been shown to have beneficial effects on pathogenic factors involved in the development of atherosclerosis. The aim of this study was to assess the effects of curcumin phytosomes on atherosclerosis induced by high-fat diet in rabbits. A total of 16 adult male New Zealand white rabbits (1.8-2 kg) were fed with a diet containing 0.5% cholesterol for 4 weeks. The rabbits were randomly divided into four groups of four animals each. Group I orally received PBS for 4 weeks. Group II animals were treated with curcumin-phosphatidylcholine solid state dispersion (Meriva®, Indena, Italy) suspended in normal saline at doses equivalent to 100 mg/kg of curcuminoids per day p.o., for 4 weeks. Groups III and IV were treated with curcumin-phosphatidylserine solid state dispersion (Meriserin®, Indena, Italy) suspended in normal saline at doses equivalent to 10 and 100 mg/kg of curcuminoids, respectively, per day p.o., for 4 weeks. For atherosclerosis evaluation, histological examinations on aortic arch section were performed. Blood samples were obtained to determine lipid profile and high-sensitivity C-reactive protein (hs-CRP) levels. Curcumin-phosphatidylserine (100 mg/kg) therapy resulted in a significant reduction in grading of atherosclerotic plaque and intima/media thickness ratio (P < 0.05) and decreased presence of inflammatory cells in the atherosclerotic lesions compared to the control group. However, no significant differences were observed between the curcumin-phospholipid preparations and the control group regarding lipid profile and hs-CRP levels. Results of the present study revealed an atheroprotective effect of curcumin-phosphatidylserine (100 mg/kg) solid dispersion as revealed by a reduction in the development of atherosclerotic lesions.

ABSTRACT

Today, there is an increased tendency to use herbal remedies. Rhubarb refers to several species of the genus Rheum L. in the Polygonaceae family. This species-rich genus is mainly distributed in Asian countries. Several medicinal effects have been attributed to the Rheum spp. in the traditional and modern medicine such as healing lungs, liver, kidney, womb and bladder diseases, cancer, diabetes, insect bites, relapsing fevers, diarrhea and constipation. Various in vitro, in vivo and clinical studies have investigated the therapeutic effect of extracts, fractions and pure compounds isolated from different species of this genus. Considering the positive findings, several pharmaceutical formulations containing rhubarb extract like capsules, drops, mouthwashes and different topical formulations are now present in the market. However, there are other traditional therapeutic effects of rhubarb that have not been studied yet and it is of great importance to perform confirmatory experiments or clinical investigations. The current review summarizes general information regarding botany, phytochemistry, ethnobotany and pharmacological aspects of Rheum spp. It is hoped that the present review could motivate subsequent research on the other medicinal properties of these plants that have been neglected until today.

ABSTRACT

Actaea racemosa (AR) also known as Cimicifuga racemosa, is a perennial plant from Ranunculaceae family which was used as traditional remedies in treatment of various condition like rheumatoid muscular pain, headache, inflammation and dysmenorrhea. Actaea racemosa was basically native to Canada and the Eastern United State. This chapter proposed the ethnopharmacological uses of Actaea racemosa, and its phytochemical properties. Specifically, in this article we focused on use of Actaea racemose for menopausal and post-menopausal symptoms management. Electronic databases including PubMed and Scopus were searched for studies on Actaea racemose and its administration in management of menopausal symptoms. Chem Office software was also used in order to find chemical structures. The key words used as search terms were Cimicifuga racemose, Actaea racemose, Ranunculaceae, Black cohosh, Menopausal symptoms. We have included all relevant animal and human studies up to the date of publication. The analysis on Actaea racemose showed various indications for different plant's extracts. Approximately 131 chemical compounds have been isolated and identified from Actaea racemosa. According to recently studies, the most important chemicals known of the Actaea racemosa are phenolic compounds, chromones, triterpenoids, nitrogen-containing constituents. In addition, in vivo and in vitro studies reported wide range of pharmacological activities for Black cohosh like attenuating menopausal symptoms. Mechanism of action for some ethnomedicinal indications were made clear while some of its activities are not confirmed by pharmacological studies yet. Further investigations on its pharmacological properties are necessary to expand its clinical effective use. Also, additional large clinical trials are recommended for clarifying the effect of Black cohosh.

ABSTRACT

Discovering new drugs for treating different health problems is one of the basic needs of human societies. There are various strategies to find new lead compounds. One of the most important strategies in this regard is using the knowledge in traditional and folk medicines as a valuable guide. Islamic traditional medicine (ITM) is a well reputed school of medicine with a long history. In the textbooks of this medical system, the properties and applications of many medicinal plants have been described. As a part of an ongoing project on plants used in ITM, in this study we investigated botany, traditional uses, phytochemistry, and pharmacology of Berberis spp. The great genus Berberis (Berberidaceae) consists of 594 species worldwide which have been used in different traditional medicines for a wide range of diseases. In ITM reference books such as Al-Hâwi fi'at-Tibbe (Comprehensive Book of Medicine), Kâmel al-Sinâh at-Tibbiyah (Complete Book of the Medical Art), Al-Qânun fi' at-Tibbe (Canon of Medicine), Dakhireh Khârazmshâhi (Treasure of Khârazmshâh), and Makhzan al-Adwyah (Drug Treasure), different parts of B. vulgaris and B. integrimma, known as Zereshk, have been mainly prescribed for skin, liver, stomach, kidney, and eye problems. There are several pharmacological studies reporting beneficial effects of various Berberis plants confirming traditional uses. Most of the activities reported for Berberis is attributed to the presence of an important class of alkaloids namely isoquinolines. Nevertheless, clinical studies are necessary to confirm the therapeutic effects of different species of this genus.

ABSTRACT

Centella asiatica (CA) or Gotu cola is an herbal plant from the Apiaceae family with a long history of usage in different traditional medicines. It has long been used for the treatment of various ailments such as central nervous system (CNS), skin and gastrointestinal disorders especially in the Southeast Asia. This chapter focused on the phytochemical constituent and pharmacological activities of CA based on preclinical and clinical studies. Additionally, botanical description and distribution, traditional uses, interactions, and safety issues are reviewed. Electronic databases of Google Scholar, Scopus, PubMed, and Web of Science were searched to obtain relevant studies on the pharmacological activities of CA. Approximately, 124 chemical compounds including triterpenoids, polyphenolic compounds, and essential oils have been isolated and identified from CA. Ethnomedicinal applications of CA mostly include treatment of gastrointestinal diseases, wounds, nervous system disorders, circulatory diseases, skin problems, respiratory ailments, diabetes and sleep disorders in various ethnobotanical practices. Pharmacological studies revealed a wide range of beneficial effects of CA on CNS, cardiovascular, lung, liver, kidney, gastrointestinal, skin, and endocrine system. Among them, neuroprotective activity, wound healing and treatment of venous insufficiency, as well as antidiabetic activity seem to be more frequently reported. At the moment, considering various health benefits of CA, it is marketed as an oral supplement as well as a topical ingredient in some cosmetic products. Additional preclinical studies and particularly randomized controlled trials are needed to clarify the therapeutic roles of CA.

ABSTRACT

BACKGROUND: Reaping the benefits from massive volumes of data collected in all sectors to improve population health, inform personalized medicine, and transform biomedical research requires the delicate balance between the benefits and risks of using individual-level data. There is a patchwork of US data protection laws that vary depending on the type of data, who is using it, and their intended purpose. Differences in these laws challenge big data projects using data from different sources. The decisions to permit or restrict data uses are determined by elected officials; therefore, constituent input is critical to finding the right balance between individual privacy and public benefits. OBJECTIVE: This study explores the US public's preferences for using identifiable data for different purposes without their consent. METHODS: We measured data use preferences of a nationally representative sample of 504 US adults by conducting a web-based survey in February 2020. The survey used a choice-based conjoint analysis. We selected choice-based conjoint attributes and levels based on 5 US data protection laws (Health Insurance Portability and Accountability Act, Family Educational Rights and Privacy Act, Privacy Act of 1974, Federal Trade Commission Act, and the Common Rule). There were 72 different combinations of attribute levels, representing different data use scenarios. Participants were given 12 pairs of data use scenarios and were asked to choose the scenario they were the most comfortable with. We then simulated the population preferences by using the hierarchical Bayes regression model using the ChoiceModelR package in R. RESULTS: Participants strongly preferred data reuse for public health and research than for profit-driven, marketing, or crime-detection activities. Participants also strongly preferred data use by universities or nonprofit organizations over data use by businesses and governments. Participants were fairly indifferent about the different types of data used (health, education, government, or economic data). CONCLUSIONS: Our results show a notable incongruence between public preferences and current US data protection laws. Our findings appear to show that the US public favors data uses promoting social benefits over those promoting individual or organizational interests. This study provides strong support for continued efforts to provide safe access to useful data sets for research and public health. Policy makers should consider more robust public health and research data use exceptions to align laws with public preferences. In addition, policy makers who revise laws to enable data use for research and public health should consider more comprehensive protection mechanisms, including transparent use of data and accountability.

ABSTRACT

BACKGROUND AND AIMS: Niclosamide is an established anti-helminthic drug, which has recently been shown to inhibit the growth of various cancer cells. To exploit the potential anti-tumor activity of this drug for systemic use, the problem of low aqueous solubility should be addressed. The present study tested the in vivo anti-tumor effects of a recently developed nanoliposomal preparation of niclosamide in an experimental model of colon carcinoma. METHODS: The cytotoxicity of nanoliposomal niclosamide on CT26 colon carcinoma cells was evaluated using the MTT test. Inhibition of tumor growth was investigated in BALB/c mice bearing CT26 colon carcinoma cells. The animals were randomly divided into 4 groups including: 1) untreated control, 2) liposomal doxorubicin (15 mg/kg; single intravenous dose), 3) liposomal niclosamide (1 mg/kg/twice a week; intravenously for 4 weeks), and 4) free niclosamide (1 mg/kg/twice a week; intravenously for 4 weeks). To study therapeutic efficacy, tumor size and survival were monitored in 2-day intervals for 40 days. RESULTS: In vitro results indicated that nanoliposomal and free niclosamide could exert cytotoxic effects with IC50 values of 4.5 and 2.5 µM, respectively. According to in vivo studies, nanoliposomal niclosamide showed a higher growth inhibitory activity against CT26 colon carcinoma cells compared with free niclosamide as revealed by delayed tumor growth and prolongation of survival. CONCLUSION: Nnaoliposomal encapsulation enhanced anti-tumor properties of niclosamide in an experimental model of colon carcinoma.

ABSTRACT

ETHNOPHARMACOLOGICAL RELEVANCE: Borago L., (family Boraginaceae) is a small genus of annual or perennial herbs with branched flowers, which is commonly found in the Mediterranean region. Some species known as Gavzabȃn in Asian and some African countries are traditionally used instead of Borago. Aims of the review: The purpose of this study was to provide comprehensive scientific information on phytochemistry, traditional uses and pharmacological activities of Borago species to provide an insight into further research on the therapeutic potential of these plants. In many studies, it has been shown that different parts of Borago species, including leaves, flowers, seeds, roots and aerial parts possess numerous ethnobotanical values. MATERIALS AND METHODS: All ethnobotanical, phytochemical, pharmacological, and clinical data were collected from online journals, magazines and books (all of which were published in English, Arabic, and Persian) from 1968 to 2018. Electronic databases such as Google, Google Scholar, PubMed, Science Direct, Researchgate, and other online collections were used. RESULTS: The phytochemical studies on five species showed a wide range of phytochemicals belonging to different classes of secondary metabolites. From a pharmacological point of view, different extracts and fractions, essential oils, and pure compounds isolated from various Borago species have shown diverse activities in in vitro, in vivo, and clinical studies confirming various traditional uses of Borago genus. CONCLUSION: Considering the reported activities of the Borago genus both in traditional and modern medicine, further studies on biological aspects and identification of the mechanism of action for drug discovery are highly required.

ABSTRACT

BACKGROUND: Niclosamide is an FDA-approved and old anti-helminthic drug used to treat parasitic infections. Recent studies have shown that niclosamide has broad anti-tumor effects relevant to the treatment of cancer. However, this drug has a low aqueous solubility hindering its systemic use. Herein, we report the preparation and characterization of niclosamide nanoliposomes and their in vivo anti-tumor effects. METHODS: Nanoliposomes were prepared using thin-film method and the drug was encapsulated with a remote loading method. The nanoliposomes were investigated by the observation of morphology, analysis of particle size and zeta potential. Additionally, qualitative and quantitative analyses were performed using HPLC. We assessed the in vitro cytotoxicity of the nanoliposomal niclosamide on B16F10 melanoma cells. Inhibition of tumor growth was investigated in C57BL/6 mice bearing B16F0 melanoma cancer. RESULTS: Analytical results indicated that the nanoliposomal system is a homogeneous and stable colloidal dispersion of niclosamide particles. Atomic force microscopy images and particle size analysis revealed that all niclosamide particles had a spherical shape with a diameter of approximately 108nm. According to in vitro and in vivo studies, nanoliposomal niclosamide exhibited a better anti-tumor activity against B16F10 melanoma tumor compared with free niclosamide. CONCLUSION: Nanoliposomal encapsulation enhanced the aqueous solubility of niclosamide and improved its anti-tumor properties.

ABSTRACT

Turmeric extracts contain three primary compounds, which are commonly referred to as curcuminoids. They are curcumin, demethoxycurcumin (DMC), and bisdemethoxycurcumin. While curcumin has been the most extensively studied of the curcuminoids, it suffers from low overall oral bioavailability due to extremely low absorption as a result of low water solubility and instability at acidic pH, as well as rapid metabolism and clearance from the body. However, DMC, which lacks the methoxy group on the benzene ring of the parent structure, has much greater chemical stability at physiological pH and has been recently reported to exhibit antitumor properties. However, the treatment of noncancerous diseases with DMC has not been comprehensively reviewed. Therefore, here we evaluate published scientific literature on the therapeutic properties of DMC. The beneficial pharmacological actions of DMC include anti-inflammatory, neuroprotective, antihypertensive, antimalarial, antimicrobial, antifungal, and vasodilatory properties. In addition, DMC's ability to ameliorate the effects of free radicals and an environment characterized by oxidative stress caused by the accumulation of advanced glycation end-products associated with diabetic nephropathy, as well as DMC's capacity to inhibit the migration and proliferation of vascular smooth muscle cells following balloon angioplasty are also addressed. This review collates the available literature regarding the therapeutic possibilities of DMC in noncancerous conditions.

ABSTRACT

Objectives: Hepatocellular carcinoma is one of the most frequent cancers worldwide, for the treatment of which various therapy protocols and drugs have been introduced; however, none of them has suppressed cancer tissues completely. New research programs have been developed on cancer and the accompanied effects of novel synthesized compounds on cancer cell lines. Our latest reports on the molecular basis of cancer revealed a pattern of changes in gene expression triggered in the cancer pathway. Methods: HepG2 cell lines were cultured under similar conditions in both test and control groups. The IC50 concentration of the (2R, 4S)-N-(2, 5-difluorophenyl)-4-hydroxy-1-(2, 2, 2-trifluoroacetyl) pyrrolidine-2-carboxamide compound was used in the treatment group. After 48 hours from the culture, the expressional profiles of apoptosis pathway genes (84 genes) were studied using the PCR array method. Results: The findings demonstrated that the expression of some apoptosis-related genes pertaining to TNF, BCL2, IAP, and caspase families was regulated by (2R, 4S)-N-(2, 5-difluorophenyl)-4-Hydroxy-1-(2, 2, 2-Trifluoroacetyl) Pyrrolidine-2-Carboxamide. In the same vein, an alteration was observed in the expression of both pro-apoptotic and anti-apoptotic genes associated with the extrinsic and intrinsic apoptosis signaling pathways. Conclusions: According to the data obtained, the pyrrolidine-2-carboxamide compound was demonstrated to be able to regulate the apoptotic activities of HepG2 cells by affecting both pro-apoptotic and anti-apoptotic relevant genes.

ABSTRACT

ETHNOPHARMACOLOGICAL RELEVANCE: The genus Curcuma, which is the most important source of curcumin, has been widely used in different traditional medicines. Various species of Curcuma have long been used for several purposes such as healing wounds, liver disorders, jaundice and also as a blood purifier. AIM OF THE STUDY: This review focused on the ethnopharmacological uses and phytochemical aspects of Curcuma. Additionally, in this study, the different properties of two species of Curcuma in Islamic Traditional Medicine (ITM), C. longa and C. zedoaria, as well as their pharmacological aspects in modern medicine are reviewed. MATERIALS AND METHODS: ITM literatures were searched to find Curcuma's applications. Also, electronic databases including PubMed and Scopus were searched to obtain studies giving any in vitro, in vivo or human evidence of the efficacy of C. longa and C. zedoaria in the treatment of different diseases. ChemOffice software was used to find chemical structures. RESULTS: The analysis showed that ethno-medical uses of Curcuma have been recorded for centuries. Approximately, 427 chemical compounds have been isolated and identified from Curcuma spp. This genus is rich in flavonoids, tannins, anthocyanin, phenolic compounds, oil, organic acids and inorganic compounds. Curcumin is one of the main active ingredients in Curcuma which has strong anti-inflammatory and antioxidant effects. Besides, pharmacological studies have indicated wide range of Curcuma's activities, such as hepato-protective, antifungal, antihypertensive and neuroprotective. CONCLUSIONS: In this study, we reviewed various studies conducted on ethno-medicinal, ITM properties and photochemistry of Curcuma spp. Also, pharmacological activities of two species, C. longa and C. zedoaria are summarized. Pre-clinical investigations have demonstrated some of the traditional aspects of Curcuma, such as wound healing, anti-arthritic, anti-tumor and liver protective activities. These could be related to antioxidant and anti-inflammatory properties of Curcuma which might be due to high amounts of phenolic compounds. Curcuma is mentioned to have neural tonic properties in ITM which have been confirmed by some animal studies. Considering various preclinical studies on C. longa and C. zedoaria and their active ingredient, curcumin, randomized controlled trials are warranted to confirm their promise as a clinically effective hepato and neuro-protective agents.
