RESUMEN
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.

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.

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.

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.
RESUMEN
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.
RESUMEN
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.

INTRODUCTION: Considering people's tendency to self-treatment, efforts to address the broad aspects of health literacy are extremely important. 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.
RESUMEN
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.

Extensive in vitro studies have been conducted to evaluate the anticancer activity of oral hypoglycemic agents. Many of these studies experienced detrimental limitations, since they were conducted on cancer cells commonly grown in culture media consisting of extremely high concentrations of growth factors and glucose. The present study was aimed at exploring the antiproliferative effects of the commonly studied metformin and the less frequently reported phenformin oral hypoglycemic agents on different molecular subtypes of breast cancer under rich glucose and glucose deprived conditions. Our results indicate that under glucose deprived conditions, which better reflect the factual glucose-starved solid tumors in vivo, biguanides exert more antiproliferative activities against the three molecular subtypes of breast cancer cell lines examined in this study. In addition, the observed antiproliferative activities of biguanides appear to be mediated by apoptosis induction in breast cancer cells. This induction is significantly augmented under glucose deprived conditions.

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.
