Unveiling the factors influencing public knowledge and behaviours towards medication errors in Jordan: a cross-sectional study.

BACKGROUND: Medication errors are preventable incidents resulting from improper use of drugs that may cause harm to patients. They thus endanger patient safety and offer a challenge to the efficiency and efficacy of the healthcare system. Both healthcare professionals and patients may commit medication errors. METHODS AND OBJECTIVES: A cross-sectional, observational study was designed using a self-developed, self-administered online questionnaire. A sample was collected using convenience sampling followed by snowball sampling. Adult participants from the general population were recruited regardless of age, gender, area of residence, medical history, or educational background in order to explore their practice, experience, knowledge, and fear of medication error, and their understanding of this drug-related problem. RESULTS: Of the 764 participants who agreed to complete the questionnaire, 511 (66.9%) were females and 295 (38.6%) had a medical background. One-fifth of participants had experienced medication errors, with 37.7% of this segment reporting these medication errors. More than half of all medication errors (84, 57.5%) were minor and thus did not require any intervention. The average anxiety score for all attributes was 21.2 (The highest possible mean was 36, and the lowest possible was 0). The highest level of anxiety was seen regarding the risk of experiencing drug-drug interactions and the lowest levels were around drug costs and shortages. Being female, having no medical background, and having experience with medication errors were the main predictors of high anxiety scores. Most participants (between 67% and 92%) were able to recognise medication errors committed by doctors or pharmacists. However, only 21.2 to 27.5% of participants could recognise medication errors committed by patients. Having a medical background was the strongest predictor of knowledge in this study (P < 0.001). CONCLUSION: The study revealed that the prevalence of self-reported medication errors was significantly high in Jordan, some of which resulted in serious outcomes such as lasting impairment, though most were minor. Raising awareness about medication errors and implementing preventive measures is thus critical, and further collaboration between healthcare providers and policymakers is essential to educate patients and establish effective safety protocols.

Assessment of knowledge and awareness of stroke among the Syrian population: unveiling the current landscape in Syria through the first nationally representative study.

Stroke is a global public health concern, contributing to high rates of morbidity and mortality. In Syria, the current conflict and associated challenges have had a profound impact on healthcare infrastructure, including education and awareness programs related to stroke. An essential aspect of preventing stroke is the awareness of individuals. The study aimed to investigate factors associated with knowledge and awareness of stroke among Syrian people. A cross-sectional national representative study was conducted in Syria. The questionnaire was created on Google form and disseminated as a link through online platform social media like Facebook, WhatsApp, and Twitter. The population of the study was divided using proportionate random sampling into the 14 governorates. A random sample was selected from each area. The STROBE reporting guideline for cross-sectional studies was followed. Logistic regression analysis was performed to identify the factors associated with poor knowledge of stroke. A total of 1013 Syrian adults participated in the study. With more than half of them were females (53.5%) and employed (55.6%). Significant associations were found between ability to identify at least one correct risk factor and employability status (p = 0.029), single group (p = 0.036) and smokers (p < 0.001). In addition, significant associations were found between identifying at least one correct stroke symptom and smokers (p < 0.001) and no-obese people (p = 0.048). Furthermore, younger age group (below 30 years) were significantly able to list at least one correct stroke consequence compared to the older age groups (p = 0.025). Moreover, a significantly higher number of smokers compared to non-smokers correctly identified at least one stroke consequence (p = 0.019). The study revealed that there is a relatively weak understanding of the preventable nature of stroke among Syrian population. The overall awareness is still inadequate and varies depending on lifestyle factors and employment status.

Prescribing Patterns of Isotretinoin for Acne Among Dermatologists in Central Jordan.

INTRODUCTION: Prescribing practices among dermatologists play a crucial role in managing acne, particularly concerning medications like isotretinoin. In Jordan's central region, encompassing the Governorates of Amman, Balqa, Zarqa, and Madaba, dermatologists in both public and private sectors encounter diverse cases of acne. Understanding their prescription patterns and awareness regarding isotretinoin usage is essential for optimizing acne treatment outcomes and minimizing potential risks. METHODS: This study aimed to evaluate dermatologists' practices in prescribing isotretinoin for acne. It relied on the descriptive analytical approach, with the study population including all dermatologists working in the public and private sectors in the central region of Jordan. Simple random sampling was used to include 147 male and female doctors. An online questionnaire was adopted to collect data from the study sample, which was distributed through social media platforms and messaging platforms such as Facebook, WhatsApp, and Instagram to dermatologists working in the central region. RESULTS:  In this study of 147 dermatologists, 58 (39.45%) prescribed isotretinoin primarily for severe acne, and 53 (36.06%) prescribed isotretinoin to about 50-100 patients per year, with the initial dosage based on guidelines (n=102, 69.39%). The majority (n=115; 78.23%) refrained from prescribing if liver enzymes were elevated. Pregnancy tests were required by 42 (28.57%) in the first session, while 78 (53.07%) deemed it the patient's responsibility. Common precautions included sunscreen (n=77; 52.38%) and moisturizing cream (n=31, 21.09%). Only six of the dermatologists (4.08%) advised their patients not to use contact lenses, and only 17 (11.57%) prescribed moisturizing eye drops. CONCLUSION: This study's findings emphasize how crucial physicians' experience is when it comes to prescribing isotretinoin for severe acne. Continued educational initiatives are imperative to address gaps in patient information and safeguards in order to optimize treatment outcomes and ensure patient safety.

Stroke awareness and knowledge in Sudan: a cross-sectional analysis of public perceptions and understanding.

Introduction: Stroke, a leading cause of morbidity and mortality globally, demands heightened awareness and knowledge for effective preventive strategies and tailored response. Sudan is classified as a low income country with a low rate of literacy, lack of knowledge, and awareness about diseases. Thus, this study aimed to assess stroke awareness and knowledge among Sudanese population, and identify the associated factors influencing awareness. Methods: A cross-sectional study conducted between October and November 2022 through a self-administered online survey distributed via various social media platforms. The study involved adults aged 18 years and above through snow-ball sampling technique. The survey covered general awareness and knowledge concerning stroke risk factors, consequences, and the appropriate responses taken during acute stroke attacks. Results: A total of 410 participants were enrolled in the study, majority (93.4%) were from urban area and had university degree (92.4%). Furthermore, 92.2% were aware about stroke and 74.9% were able to recognize the symptoms of stroke. Only 40.2% identified all correct answers, 96.3, 92.3, and 95.1% recognized at least one risk factor, early symptom, and consequences, respectively. Females were significantly more than males able to identify at least one risk factor. Almost all participants (99.5%) perceived stroke as a serious disease (99.5%). Notably, 86.3% would promptly transport a suspected stroke patient to the hospital. The multivariable analysis showed that females versus males and patients with depression versus without depression had significantly higher odds to identify at least one risk factor (OR of 14.716 [95% CI 1.901; 113.908] and 0.241 [95% CI 0.059; 0.984], respectively). Conclusion: The study concluded that stroke knowledge and awareness among Sudanese population is suboptimal. Furthermore, early stroke recognition and intake of the appropriate management strategies are lacking which highlights the need for targeted education and awareness campaigns.

Cannabis and cancer: unveiling the potential of a green ally in breast, colorectal, and prostate cancer.

Cancer comes in second place on the list of causes of death worldwide. In 2018, the 5-year prevalence of breast cancer (BC), prostate cancer (PC), and colorectal cancer (CRC) were 30%, 12.3%, and 10.9%, respectively. Cannabinoids are chemicals derived from the Cannabis sativa plant; the most investigated cannabinoids are cannabinol, delta 9-tetrahydrocannabinol (Δ9-THC), and cannabidiol. In humans, the endogenous endocannabinoid system consists of endocannabinoids, cannabinoids receptors (CBs), and enzymes that degrade the endocannabinoids. In this review, we will review the most recent literature for evidence that discusses the role of cannabis in the treatment of the three types of neoplasms mentioned. Studies have proved that BC cells express CB receptors; many in-vivo studies showed that cannabinoids cause apoptosis and inhibit proliferation and migration. Also, researchers found that treating BC mice with THC and JWH-133 (CB2 receptor agonist) slowed the tumor growth. Regarding CRC, cannabidiol was found to decrease the viability of chemotherapy-resistant CRC cells and inhibit metastasis by antagonizing the G-protein-coupled receptor 55 (GPR55; a novel cannabinoid receptor) necessary for metastasis. Moreover, cannabidiol had anti-angiogenetic effects by reducing the expression of vascular endothelial growth factor (VEGF) in addition to anti-inflammatory effects. Finally, studies demonstrated that PC cells highly express CB1 and CB2 receptors and that cannabinoids are capable of inhibiting the release of exosomes and microvesicles related to cancer progression. Cannabinoids also have antiproliferative, anti-invasive, anti-fibroblastic, cell cycle arrest, and proapoptotic effects on PC cells.

Knowledge and awareness of stroke in the United Arab Emirates: a cross-sectional study of the general population.

BACKGROUND: The study aimed to assess stroke knowledge among the general population in the United Arab Emirates (UAE) and determine the factors associated with stroke awareness among people. METHODS: A cross-sectional study was conducted in the UAE between September and November 2021. The general population has self-administered an online bilingual survey (Arabic and English) distributed via social media platforms. The questionnaire covered general knowledge about stroke risk factors, consequences of stroke, and responding to somebody with acute stroke attack. RESULTS: A total of 545 surveys were completed, with more than half of the participants being female (58.5%), married (55.4%) and employed (59.4%). The majority were less than 50 years old (90.5%) and had a university degree (71.0%). Many of the participants (70.8%) had a good general knowledge of stroke; however, around 20% of the participants were able to recognize all symptoms and risk factors of stroke. The most common sources of stroke-related information were the internet/social media (53.6%). Females were better able to correctly identify at least one stroke symptom and outcome than males (p=0.008). University education has significantly affected participants' ability to identify early stroke symptoms (p=0.001) correctly. In addition, diabetic people were more likely to recognize at least one stroke outcome than non-diabetic people (p=0.039). CONCLUSIONS: The knowledge of stroke was good among highly educated people and females. However, the awareness of all stroke risk factors, symptoms, consequences and risk factors was inadequate among the general population of the UAE. Thus, there is still a gap between recognition of the relevant stroke and taking action among people.

Students' Perspectives of the Economic, Financial, and Psychological Effects of Online Learning and Its Gender Association: A Cross-Sectional Study in Jordanian Universities.

INTRODUCTION: Jordan declared a quarantine in March 2020 and shut down all educational institutions in response to the COVID-19 outbreak. E-learning was a novel way to continue the educational process in the wake of the pandemic. The study evaluates online learning (OL), aiming to examine the economic, financial, and psychological effects of OL on students, as well as their concentration, university instructors' efficiency, and satisfaction with OL. This research also explores the gender association of OL effects in Jordanian universities. METHODS: This is a cross-sectional study. A self-filled questionnaire was generated using an online form and distributed to students at public and private universities through social media. The questionnaire utilized a five-point Likert scale to assess various aspects related to OL. The main evaluation involved a Chi-square test and posthoc test to examine gender-based differences in the factors associated with OL. The reliability of the questionnaire was assessed using a Kaiser-Meyer-Olkin (KMO) value of 0.721 and a Cronbach's Alpha of 0.7. RESULTS: A total of 720 responses were collected and analyzed. The results revealed a significant gender association with the economic/financial (P=0.001) and psychological (P=0.002) effects of OL. It was observed that 65.3% of students reported feeling depressed due to online learning. Moreover, a significant correlation was found between students' concentration and university instructors' efficiency (P=0.00). Interestingly, only 14.72% of students believed university instructors were 100% efficient in teaching theoretical and practical subjects. Additionally, 55% of the students expressed their desire for university instructors to record lectures for ease of access. CONCLUSION: The study concludes that OL's poor economic/financial effects disproportionately affect female students. On the other hand, male students were more likely to strongly disagree with the poor psychological effects of OL. Moreover, female students were more inclined to strongly disagree with the notion that OL has no psychological effect. Lastly, significant findings indicate that both students and university instructors share equal responsibility for the success of OL in Jordanian universities.

The Impact of the COVID-19 Pandemic on Loneliness Among University Students: A Cross-Sectional Study in Jordan.

INTRODUCTION: Loneliness is characterized by a sense of melancholy, emptiness, and despair, as well as a higher risk of both psychological and physical problems. Numerous post-coronavirus disease 2019 (COVID-19) sequela, both physically and mentally, have been caused by the global COVID-19 pandemic that has affected many people. Memory issues and loneliness were found to be uniquely correlated. The purpose of this study was to evaluate how the COVID-19 epidemic affected the levels of loneliness among Jordanian university students. METHODS: This is a cross-sectional questionnaire-based study. Google Forms were used for data collection, utilizing a three-item loneliness scale developed by the University of California, Los Angeles (UCLA), United States, which accounts for the following items: (1) how often does the participant feel about lacking companionship, (2) how often does the participant feel being left out, and (3) how often does the participant feel isolated from others. Each item was marked for three frequency levels of experience: (1) hardly ever, (2) some of the time, and (3) often. Responses to the three loneliness questions were graded on a scale of 3-9, with scores between 3 and 5 indicating "not lonely" and scores between 6 and 9 indicating "lonely." RESULTS: The study included 802 participating students. Specifically, 75.4% of the participants were females, 58% were aged 20-25, and 39% were 17-19. In addition, 37% were from the capital city, while 28% lived in the middle area. Seventy nine percent were from public universities, and 74% were studying in their second year. According to UCLA's three-item loneliness scale, 411 (51.2%) participants were lonely, while 391 (48.8%) participants were not feeling lonely. According to direct question answers, 576 (71.8%) participants were lonely, and 226 (28.2%) were not lonely. CONCLUSION: The study concluded that the frequency of loneliness was high among Jordanian university students. However, both genders experienced equal levels of loneliness, while younger participants felt more lonely than older ones.

Identifying psychosocial problems, needs, and coping mechanisms of adolescent Syrian refugees in Jordan.

Background: Refugees who have fled war zones are at a heightened risk of psychosocial problems that can impact their ability to function in day-to-day life and place a significant burden on the family structure. This study aimed to assess the psychosocial problems and needs and coping mechanisms of Adolescent Syrian refugees in Jordan. Methods: Between October and December 2018, we conducted a qualitative study using semi-structured interviews with a sample of key and individual informants. Our sample included 20 primary healthcare professionals, 20 schoolteachers, 20 Syrian parents, and 20 adolescents aged 12-17 years. All interviews were transcribed verbatim, and we utilized thematic analysis to group, categorize, and analyze the original Arabic language transcripts. To ensure thorough analysis, we adopted a bottom-up inductive approach that covered the six-phase iterative process proposed by Braun and Clarke. Results: The main psychosocial problems encountered by Syrian adolescents included stress, depression, loneliness, lack of a sense of security, isolation, aggressiveness, fear of war, and family disintegration. Almost all schoolteachers reported that they observed that Jordanian adolescents are more settled, self-confident, and financially stable relative to their Syrian peers. The Jordanian government and community were praised for their support, including education, recreational centers, health services, and awareness campaigns. Going to school, praying and reading the Holy Quran, listening to music, and talking to friends and engaging with them were reported as the main coping mechanisms. The majority of respondents said that more services are still needed for adolescents, including more places for entertainment, psychosocial support and psychological counseling, medical care, job creation, and providing health insurance. Conclusion: Syrian refugees are aware of the psychological aspects of their situation, but they are not always able to access clinic-based humanitarian assistance for mental health and psychosocial support. Stakeholders must interact with refugees to learn about their needs and develop services that are appropriate for their culture.

The study aimed to find out the level of health literacy related to the use of retinol creams among female undergraduate students of the Faculty of Artificial Intelligence at Al-Balqa Applied University. METHODS: This study adopted an analytical descriptive research methodology by designing and applying a questionnaire tool. The questionnaire consisted, after arbitration and testing its validity and stability, of 15 items. Each item represents one of the indicators for measuring the level of health literacy about the use of retinol creams. The sample of the study was a random sample of female students in the Faculty of Artificial Intelligence at Al-Balqa Applied University. RESULTS: A total of 221 undergraduate female students were enrolled in the study. The most important results were that the arithmetic mean for estimating the level of health culture among female students in the study on the use of retinol creams was 3.117 out of 5, with a relative weight percentage of 62.3% and an average total score on the general level of indicators of total health culture. CONCLUSION: This study provided insights into the health literacy related to the use of retinol creams among female students. While the students demonstrated a high level of health education in some aspects, there were areas where their knowledge and practices could be improved. These findings can contribute to the development of educational programs and interventions aimed at promoting the safe and informed use of retinol creams among university students.

Perception of Jordanian pharmacy students towards community pharmacy-virtual training experience during COVID-19 outbreak

Background: This study aims to assess the perception of pharmacy students towards this new modality of training during CoViD-19 period. Methods: Senior pharmacy students were included in this study. Accredited and certified community pharmacy preceptors were asked to simulate the community pharmacy training and record that as videos, which were evaluated and assessed by expert academics before being delivered to students. A validated online questionnaire was then distributed for self-administration electronically to evaluate their perception. Results: A convenience sample (n=109) of senior pharmacy students were recruited. The majority of the participants were females (70.6%) and the median age of students was 22.0 years (IQR= 1). Around half of the participants showed positive perceptions towards the virtual training module and the pharmacy training preceptors. A 46.8% of the students benefited from the virtual training in time management, and 43.1% in developing lifelong learning skills. The absence of eye contact during the learning was the most important barrier revealed by the students (52.3%). Half of the students agreed/strongly agreed that combining the virtual and conventional techniques for future training would improve training outcomes. Conclusion: While students had an overall positive experience, there were many hurdles that need to be addressed, such as lack of communication and technical support. This spot the light on the crucial need to continually improve and redesign our experiential education; to achieve optimum learning outcomes for students. (AU)

Factors associated with knowledge and awareness of stroke in the Iraqi population: a cross-sectional study.

Introduction: Stroke is a highly prevalent condition with high rates of death and disability in Iraq and around the world. Knowledge of stroke and its associated risk factors is essential for disease prevention and rapid response when confronted with a stroke patient. Purpose: The purpose of this study is to assess stroke knowledge and identify factors associated with awareness among the Iraqi public. Material and methods: A questionnaire-based, cross-sectional survey was conducted on the Iraqi population. The self-administered online questionnaire contained three sections. The study got ethical approval from the Research Ethics Committee at the University of Baghdad. Results: The results showed that 26.8% of the participants reported knowledge regarding identifying all risk factors. In addition, 18.4% and 34.8% of the participants recognized all symptoms and mentioned all possible consequences of stroke, respectively. Previous medical history with chronic diseases had essential relationships with the response when faced with a person having an acute stroke. In addition, there was a significant relationship between gender, smoking history, and identification of early stroke symptoms. Conclusion: There was a lack of knowledge about risk factors for stroke among the participants. There is a need for an awareness program among the Iraqi people to raise their understanding of stroke that can reduce stroke mortality and morbidity.

Anti-Proliferative Effect of Potential LSD1/CoREST Inhibitors Based on Molecular Dynamics Model for Treatment of SH-SY5Y Neuroblastoma Cancer Cell Line.

BACKGROUND: Lysine-specific demethylase is a demethylase enzyme that can remove methyl groups from histones H3K4me1/2 and H3K9me1/2. It is expressed in many cancers, where it impedes differentiation and contributes to cancer cell proliferation, cell metastasis and invasiveness, and is associated with inferior prognosis. LSD1 is associated with its corepressor protein CoREST, and utilizes tetrahydrofolate as a cofactor to accept CH2 from the demethylation process. The fact that the cofactor is best bound to the active site inspired us to explore its interactions to LSD1/CoREST enzyme complex utilizing molecular dynamics simulation, which aids designing novel and potent inhibitors. OBJECTIVE: In this study we minted to identify a new potential LSD1/CoREST inhibitors and test the potency and the safety of such inhibitors against human neuroblastoma and fibroblast cells lines. METHODS: We have implemented a previously derived model from the molecular dynamics simulation study and the key contacts to the active site in a subsequent structure based drug design and in-silico screening, which revealed a number of potential inhibitors toward LSD1/CoREST complex. The anti-proliferative activities of the identified compounds will be tested against neuroblastoma SH-SY5Y cancer cell line which known to highly express LSD1/CoREST complex. RESULTS: In-silico mining on National Cancer Institute (NCI) database identified 55 promising and structurally diverse inhibitors. Applying the abovementioned molecular modeling procedure yielded four compounds of LSD1/CoREST inhibiters with IC50 < 2µM. The four lead compounds were tested against SH-SY5Y neuroblastoma cell line that known to express high level of LSD1 and illustrated a potent activity with an IC50 ranging from 0.195 to 1.52µM. To estimate the toxicity of the selective leads, they were tested against normal fibroblast cells and scored a relatively high IC50 ranging from 0.303 to ≥ 100µM. CONCLUSION: Our model revealed promising inhibitors that can be used in treating cancers that overexpress the LSD1 enzyme such as the SH-SY5Y neuroblastoma.

Pharmacists' Perception of the Coronavirus Pandemic (COVID-19) in Jordan: A Cross-Sectional Study.

OBJECTIVES: To analyze the role of pharmacists during the COVID-19 pandemic, to measure pharmacists' attitude toward COVID-19 safety measures (wearing masks, wearing gloves, isolation shield, good hygiene, etc.), and explore their perspectives regarding a second wave of the virus. METHODS: This cross-sectional online survey study was conducted in Jordan during the COVID-19 outbreak in July 2020 to discuss Jordanian pharmacists' awareness of safety at their workplace during the COVID-19 outbreak, their sources of information, and their predictions for COVID-19 vaccination. RESULTS: The participants (n = 311) were all pharmacists mostly aged between 23-30 years old (45%) and female (83%). The primary source of information about COVID-19 was social networking (38.9%). Pharmacists were committed to social distancing (86.5%) and wearing masks (76.2%). They expressed levels of agreement to their role in decreasing COVID-19 spread (94.2%) and correcting false information (94.5%); they expressed levels of expectation toward concern about a second COVID-19 wave (83%) that would be more severe than the previous one (43.4%). Pharmacists expected that an influenza vaccine might be helpful in decreasing severity and spread of the COVID-19 pandemic (56.9%). Pharmacists expected COVID-19 vaccine development within 6 months of administering our study survey (84.9%) and that vaccination might be effective in preventing COVID-19 (93%) infection. CONCLUSION: Pharmacists expressed positive roles on COVID-19 spread through exemplary actions, self-commitment to protection measures, and public health awareness. Social media as a source of health information should be cautiously investigated, and pharmacists should always refer to evidence-based sources. The role of pharmacists is particularly important for the upcoming era of COVID-19 vaccination administration and awareness.

Factors Associated with Knowledge and Awareness of Stroke Among the Jordanian Population: A Cross-Sectional Study.

Background and objective: Stroke is the second leading cause of death in Jordan and over the world. Knowledge and awareness towards stroke play a crucial role in the management and prevention of its complications. This study aims to assess the knowledge and awareness about stroke among the Jordanian population and determine factors associated with stroke awareness. Methods: This cross-sectional study through a web-based anonymous questionnaire that needed 10 minutes to be completed. It examined sociodemographic characteristics and recognition of the risk factors, warning signs, stroke consequences, and early response to stroke symptoms. Logistic regression analysis identified the factors associated with poor knowledge of stroke.  Results: A total of 573 Jordanian adults participated in this study. The participant's ability to identify at least one early symptom of stroke and the proper response to the symptoms were significantly correlated with the educational level (OR of 3.4 and 2.5, respectively). At least one consequence of stroke was significantly associated with different demographic factors such as gender, socioeconomic income, females versus males and those with medium income versus low income had significantly higher odds (OR of 6.6 and 4.1, respectively). Conclusion: This study revealed a good knowledge and awareness level about stroke among Jordanians correlated mainly with their educational level. Therefore, new strategies should be considered to decrease the prevalence of stroke in Jordan, including the need for engagement in enhanced awareness campaigns.

The impact of pharmaceutical care on the efficacy and safety of transdermal glucosamine sulfate and capsaicin for joint pain.

Background Arthritis is a common chronic joint disease. It progressively causes joint pain, stiffness, and disability. Glucosamine sulfate has been shown to be an effective symptom-relieving biological agent. Pharmaceutical care, including patient counseling, is very important to overcome inconsistencies in compliance and adherence. Objective The aim of this study is to evaluate the impact of pharmaceutical care on the efficacy and safety of transdermal glucosamine sulfate and capsaicin (TGC-Plus cream) in the management of chronic joint pain. Settings A rheumatology outpatient clinic, Jordan University Hospital, Amman, Jordan. Methods A cross sectional study with a single treatment group was conducted. One hundred (100) patients diagnosed with either osteoarthritis, rheumatoid arthritis or chronic joint pains were recruited. Patients started on TGC-Plus cream applied twice daily for duration of 12 weeks. Patients received pharmaceutical care services during the study duration. Main outcome measure Efficacy and safety of TGC-Plus cream in pain relief and joint function improvement (alleviating joint stiffness) the need of alternative analgesics and number of doctor's visits. Results There was a significant reduction of numerical pain score (7 ± 1.40 vs. 3.53 ± 2.13, p < 0.05), with significant reduction in the limitation of joint movement (6.18 ± 2.14 vs. 3.47 ± 2.23, p < 0.05) after 12 weeks. In addition, the need for analgesics and the number of doctor's visits were significantly reduced (1.99 ± 2.77 vs. 0.71 ± 1.90, p < 0.05), (1.11 ± 1.28 vs. 0.06 ± 0.293, p < 0.05) respectively. Conclusion Pharmacist supervised treatment with the TGC-Plus cream significantly reduces pain and enhances locomotor function in patients with chronic pain who failed to achieve adequate prior pain relief.

Oral contraceptive and breast cancer: do benefits outweigh the risks? A case - control study from Jordan.

BACKGROUND: Oral contraceptives (OCs) use has been linked to increased risk of breast cancer (BC) in several reports from the world. Limited number of similar studies have been conducted in the Middle Eastern female population. This study aimed to explore any possible correlation between the contemporary and duration of OCs use among Jordanian women and the risk of breast cancer. METHODS: A case control study was conducted in 450 Jordanian women (225 as cases and 225 as controls), aged 18 to 65. Chi-square test was used to study the association between risk of breast cancer and different factors. Mann Whitney-U test was employed to evaluate the relation between time-dependent risk factor and breast cancer. RESULTS: Our results indicated that regular use of OCs exhibited association with increased risk of breast cancer (OR = 2.25, 95% CI 1.34-2.79; p = 0.002), while the duration of OCs use was not associated with the increased risk of breast cancer (p > 0.05). In addition, other factors demonstrated significant association with the increased risk of breast cancer such as age at puberty, age at menopause, previous pregnancies, menopausal status, and family history of cancer. CONCLUSIONS: regular use of OCs may be associated with increased risk of breast cancer in Jordanian women. A larger sample size in multi-center setting study is required to confirm this finding among the Jordanian female population.

Reactive Oxygen Species: the Dual Role in Physiological and Pathological Conditions of the Human Body.

Reactive oxygen species (ROS) are well-known for playing a dual role as destructive and constructive species. Indeed, ROS are engaged in many redox-governing activities of the cells for the preservation of cellular homeostasis. However, its overproduction has been reported to result in oxidative stress, which is considered as a deleterious process, and is involved in the damage of cell structures that causes various diseased states. This review provides a concise view on some of the current research published in this topic for an improved understanding of the key roles of ROS in diverse conditions of health and disease. Previous research demonstrated that ROS perform as potential signaling molecules to control several normal physiological functions at the cellular level. Additionally, there is a growing body of evidence supporting the role of ROS in various pathological states. The binary nature of ROS with their profitable and injurious characteristics indicates the complexities of their specific roles at a biological compartment and the difficulties in establishing convenient intervention procedures to treat ROS-related diseases.

Phenolic Compounds and Bioactivity of Cytisus villosus Pourr.

The present study focuses on the chemical composition, antioxidant, antimicrobial, and antiproliferative activities of the ethyl acetate and aqueous extracts obtained from the aerial parts of Cytisus villosus Pourr. HPLC-DAD-ESI/MSn was used to identify the phenolic compounds, being (epi)gallocatechin dimer the major compound (111 ± 5 µg/g·dw) in the aqueous extract, while myricetin-O-rhamnoside (226 ± 9 µg/g·dw) was the main molecule in the ethyl acetate extract. Both extracts exhibited good scavenging activities against DPPH radical (EC50 µg/mL of 59 ± 2 and 31 ± 2 for aqueous and ethyl acetate extracts, respectively). However, the ethyl acetate extract demonstrated more potent quenching activities than the aqueous extract. The antimicrobial activities were assessed on selected Gram-positive (Staphylococcus epidermidis) and Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacteria, as well as on pathogenic fungus Candida glabrata. The extracts possessed selective and potent antimicrobial activities against the Gram-positive bacterium (IC50 of 186 ± 9 µg/mL and 92 ± 3 µg/mL for aqueous and ethyl acetate extracts, respectively). Finally, C. villosus extracts were evaluated for their antiproliferative potential on three human cancer cell lines representing breast and colon cancers. Although both extracts demonstrated sufficient growth inhibition of the three different cell lines, the ethyl acetate extract exhibited higher activity (LD50 values of 1.57 ± 0.06 mg/mL, 2.2 ± 0.1 mg/mL, and 3.2 ± 0.2 mg/mL for T47D, MCF-7, and HCT-116 cell lines). Both the extracts obtained from the aerial parts of C. villosus revealed very promising results and could be applied as functional agents in the food, pharmaceutical, and cosmeceutical industries.

Chemical composition, antioxidant, antimicrobial and Antiproliferative activities of essential oil of Mentha spicata L. (Lamiaceae) from Algerian Saharan atlas.

BACKGROUND: Mentha spicata (M. spicata) is a member of Lamiaceae that spreads mainly in the temperate and sub-temperate zones of the world. It is considered as a rich source of essential oils, which is widely used in pharmaceutical industries and food production. The objectives of the current study were to evaluate chemical composition, antioxidant, antimicrobial and antiproliferative activities associated with the essential oil of M. spicata cultivated in Algerian Saharan Atlas. METHODS: The aerial parts of M. spicata were subjected to hydrodistillation to produce the oil. Chemical identification of the oil composition was conducted by GC and GC-MS analyses. The antioxidant activity of the hydrodistilled oil was studied using DPPH, ABTS radical scavenging and ferric-reducing power assay. Antimicrobial potential was characterized against two microorganisms, signifying Gram positive, and Gram negative bacteria, and one Candida species. The microdilution method was employed to determine the minimum inhibitory concentration (MIC). The oil's antiproliferative effects against three human tumor cell lines were also investigated using the MTT assay, and the toxic doses that yielded 50% reduction of cell viability (LD50) were reported. RESULTS: Chemical analysis of the essential oil composition revealed 44 unique compounds with oxygenated monoterpenes (67.2%), followed by monoterpene hydrocarbons (20.8%), as the most abundant chemical components. Essential oil of M. spicata demonstrated moderate antioxidant activities as well as moderate to weak antimicrobial activities with best susceptibility observed for Gram positive bacteria towards the oil. In addition, anticancer activities that are associated with the oil against three human cancer cell lines were observed with LD50 values of 324 µg/mL, 279 µg/mL, 975 µg/mL against T47D, HCT-116 and MCF-7 cell lines, respectively. CONCLUSION: The results suggest that M. spicata essential oil may have potential value as a bioactive oil, for nutraceutical and medical applications, with its antioxidant, antimicrobial and antiproliferative activities.
