RESUMEN

Objective: This study aimed to provide a comprehensive overview of self-medication practices among students by conducting a bibliometric analysis of the available scientific literature. This research highlights the importance of promoting safe and responsible healthcare behaviors among students. Methods: A systematic search was conducted in the Scopus database to retrieve all peer-reviewed English articles and reviews published from 1968 onwards. The retrieved documents were analyzed to identify publication trends, citation counts, top journals, geographical distribution, and emerging research themes. Results: The findings indicate a significant increase in published literature about student self-medication over the past fifteen years. However, it was observed that the citation count for these documents was lower than expected, suggesting a need for increased attention toward this critical topic. The analysis also identified several hot topics in student self-medication, including the misuse of over-the-counter medications, dietary supplements, and psychoactive substances. The inappropriate use of antibiotics and the self-medication of mental health issues, such as anxiety and depression, were also identified as significant problems. Conclusions and recommendations: Self-medication among students is a complex and critical issue that requires immediate attention. This study highlights the urgent need for greater awareness and education regarding responsible self-medication practices among students. New policies, interventions, and strategies should be developed to address malpractices, misconceptions, and harmful practices related to self-medication. Educational institutions and health authorities should play a crucial role in providing students with mental health resources and support services... (AU)

RESUMEN

Aim: Our objectives were to compare the frequency of alexithymia and the alteration of quality of life in irritable bowel syndrome (IBS) and to determine the factors associated with alexithymia and quality of life deterioration. Method: This is a comparative study which collected 80 IBS patients and 80 controls. Results: Quality of life was impaired in 75% of patients vs 37.5% (p < 0.0001). The prevalence of alexithymia was 50% in patients vs 1.2% (p < 0.0001). In multivariate analysis, an impaired quality of life was associated with alexithymia (p = 0.003). The factors associated with impaired quality of life were anxiety and alexithymia. Conclusion: Alexithymia was present in half of patients with IBS and its was associated with impaired quality of life.

RESUMEN

OBJECTIVES: We aimed to evaluate the levels of serum lipoprotein a, LP (a), in Jordanian patients with type 2 diabetes mellitus (DM); and to examine its relation to glycemic control, metabolic syndrome (MS) and duration of DM. The LP (a) is considered one of the independent risk factors for coronary artery disease (CAD) in the general population. METHODS: Fasting blood samples were drawn from 51 diabetic patients with type 2 DM and 31 non-diabetic age and sex control subjects. Serum LP (a) was measured along with other parameters, including triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c) and glycosylated haemoglobin (HbA1c). Correlation analyses were performed between LP (a) and the various variables measured. RESULTS: LP (a) measurement showed a skewed distribution towards the lower levels in both groups. Mean LP (a) levels showed a statistically insignificant difference between the two groups. No correlations of LP (a) were observed with age, sex or body mass index (BMI). No correlations of LP (a) with LDL-c, HDL-c, TG, TC, MS, DM duration or HbA1c were observed. The LP (a) serum levels were significantly higher in type 2 diabetic patients with retinopathy. CONCLUSIONS: LP (a) serum levels are not increased in type 2 diabetic patients; so, LP (a) may not be a reliable marker for early therapeutic interventions in DM patients, even in high-risk for thrombosis groups.

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.

RESUMEN

The adipose tissue is not only an inert storage depot for lipids, but also it secretes a variety of bioactive molecules, known as adipokines, which affect whole-body homeostasis. Adiponectin is the most abundant of these adipocytokines and is known to have a regulatory effect on the metabolism of glucose and lipid. The main objectives of this study were to evaluate the serum levels of adiponectin and to establish a correlation between adiponectin serum levels and the degree of insulin resistance in type 2 diabetic patients. Eighty participants were enrolled in this study; 61 type 2 diabetic patients and 19 apparently healthy subjects. Serum level of adiponectin was measured by enzyme-linked immunosorbent assay (ELISA) for each participant. Data collection sheet was filled with all required information for each participant. Adiponectin level in the diabetic patients (5.05 ± 2.61 µg/ml) was lower than in non-diabetic healthy controls (5.71 ± 2.35 µg/ml). When the results were compared according to gender, diabetic females showed significantly higher adiponectin levels (5.76 ± 2.64 µg/ml) than diabetic males (4.366 ± 2.43 µg/ml, P = 0.035). In addition, female diabetic patients with abdominal obesity (waist circumference (WC) â©¾ 88 cm) had lower adiponectin levels (5.58 ± 2.58 µg/ml) than diabetic females without abdominal obesity (6.96 ± 3.12 µg/ml). The correlation analysis indicated that adiponectin had a significant positive correlation with age (r = -0.450, P < 0.001). In conclusion, female diabetic patients had a statistically significant higher adiponectin level than male diabetic patients which could indicate a gender effect. Adiponectin levels were inversely related to insulin resistance; as patients with abdominal obesity had lower serum levels of adiponectin.

RESUMEN

Famotidine was investigated as an inhibitor of glycogen synthase kinase-3ß (GSK-3ß) in an attempt to explain the molecular mechanism of its hypoglycemic side effects. The investigation included simulated docking experiments, in vitro enzyme inhibition assay, glycogen sparing studies using animal models and single dose oral glucose tolerance test (OGTT). Docking studies showed how famotidine is optimally fit within the binding pocket of GSK-3ß via numerous attractive interactions with some specific amino acids. Experimentally, famotidine could inhibit GSK-3ß (IC50 = 1.44 µM) and increased significantly liver glycogen spares in fasting animal models. Moreover, a single oral dose of famotidine was shown to decrease the glycemic response curve after 75 g OGTT.

RESUMEN

BACKGROUND: The search for novel xanthine oxidase (XO) inhibitors with a higher therapeutic activity and fewer side effects are desired not only to treat gout but also to combat various other diseases associated with the XO activity. At present, the potential of developing successful natural products for the management of XO-related diseases is still largely unexplored. In the present study, we have screened the methanolic extracts of various Jordanian medicinal plants for their XO inhibitory activities using an optimized protocol. MATERIALS AND METHODS: The methanolic extracts of 23 medicinal plants, belonging to 12 families, were tested in vitro, at 200 µg/ml concentrations, for their XO inhibitory potential. The dose-dependent inhibition profiles of the most active plants were further evaluated by estimating the IC(50) values of their corresponding extracts. RESULTS: Six plants were found most active (% inhibition more than 39%). These plants are Salvia spinosa L. (IC(50) = 53.7 µg/ml), Anthemis palestina Boiss. (168.0 µg/ml), Chrysanthemum coronarium L. (199.5 µg/ml), Achillea biebersteinii Afansiev (360.0 µg/ml), Rosmarinus officinalis L. (650.0 µg/ml), and Ginkgo biloba L. (595.8 µg/ml). Moreover, four more plants, namely Lavandula angustifolia Mill. (28.7% inhibition), Helianthemum ledifolium (L.) Mill. (28.4%), Majorana syriaca (L.) Kostel. (25.1%), and Mentha spicata L. (22.5%) showed a XO inhibitory activity in the range of 22-30%. CONCLUSION: The study showed that many of the tested plant species are potential sources of natural XO inhibitors that can be developed, upon further investigation, into successful herbal drugs for treatment of gout and other XO-related disorders.

RESUMEN

CONTEXT: Xanthine oxidase (XO) is a key enzyme in the pathophysiological homeostasis of hyperuricemia. It catalyzes the oxidation of hypoxanthine to xanthine and then to uric acid, the reaction involves the formation of free radical intermediates and superoxide byproducts. OBJECTIVES: This study was undertaken to investigate the antioxidant, antihyperuricemic, and xanthine oxidase inhibitory potentials of Hyoscyamus reticulatus L. (Solanaceae) extract. MATERIALS AND METHODS: The antioxidant potency was measured using the ABTS•+ scavenging capacity system, which includes Trolox as a standard. The xanthine oxidase inhibitory activity of the extract was quantitated in vitro by measuring the decline in the catalytic rate of xanthine oxidase following incubations with the plant extracts and using xanthine as a substrate. The hypouricemic potential of the extract was evaluated using an in vivo model for hyperuricemia. We tested three different doses of the extract and allopurinol was used as standard antihyperuricemic positive control. RESULTS: H. reticulatus aqueous extract exhibited significant antioxidant scavenging properties (533.26 µmol TE/g dry extract weight) and inhibitory effect on xanthine oxidase activity (IC50 12.8 µg/mL). Furthermore, oral administration of the aqueous extract significantly reduced serum urate levels in oxonate-induced hyperuricemic mice in a dose-dependent manner. DISCUSSION AND CONCLUSION: Our results suggest that the aqueous extract of H. reticulatus aerial parts might have great potential as an antioxidant and a hypouricemic agent. Our lab is currently identifying the active compounds in the extract to which the biological activities could be attributed.

RESUMEN

We investigated the possible mechanisms of inhibition of colorectal carcinogenesis by green tea (GT) in azoxymethane-treated (AOM) Apc(Min/+) mice. Mice received water or a 0.6% (w/v) solution of GT as the only source of beverage. GT treatment commenced at the 8th week of age and lasted for 8 wk. The treatment caused a statistically significant reduction in the number of newly formed tumors (28%, P < 0.05). Immunohistochemical analysis showed that GT decreased the levels of beta-catenin and its downstream target cyclin D1. To probe a mechanism, we further investigated the expression of retinoic X receptor alpha (RXR alpha) in AOM/Apc(Min/+) tumors. Our results show that RXR alpha is selectively downregulated in AOM/Apc(Min/+) mouse intestinal tumors. In contrast, other retinoic receptors including retinoic acid receptor alpha (RAR alpha), RAR beta, RXR beta, and RXR gamma were all expressed in Apc(Min/+) adenomas. Furthermore, our results show that RXR alpha downregulation is an early event in colorectal carcinogenesis and is independent of beta-catenin expression. GT significantly increased the protein levels of RXR alpha. In addition, RT-PCR analysis showed that GT induced a similar increase in the levels of RXR alpha mRNA. Genomic bisulfite treatment of colonic DNA followed by pyrosequencing of 24 CpG sites in the promoter region of RXR alpha gene showed a significant decrease in CpG methylation with GT treatment. The results suggest that a low concentration of GT is sufficient to desilence RXR alpha and inhibit intestinal tumorigenesis in the Apc(Min/+) mouse.

RESUMEN

One of the liabilities of the Apc(Min) mouse as a model for colon cancer is its lack of a robust tumor response in the large bowel. In our protocol, we treated the Apc(Min) mouse with azoxymethane, a colon-selective carcinogen. This protocol induced a 4-fold increase in the number of colon tumors. We utilized this protocol to investigate the possible mechanisms of inhibition of colorectal carcinogenesis by green tea. Mice received water or a 0.6% (w/v) solution of green tea as the only source of beverage. Green tea treatment commenced at the eighth week of age and lasted for either 4 or 8 weeks. Green tea significantly inhibited the formation of new adenomas, but was ineffective against larger tumors. Mechanistically, we investigated the effects of green tea on the expression of biomarkers involved in colon carcinogenesis. Western blotting analysis showed that green tea decreased the total levels of the early carcinogenesis biomarker beta-catenin and its downstream target cyclin D1. In contrast, the expression of COX-2 was not altered. Immunohistochemical analysis showed that green tea inhibited the formation of adenomas overexpressing beta-catenin and cyclin D1, but did not reduce the number of COX-2-expressing adenomas. Our results suggest that green tea specifically targets initial stages of colon carcinogenesis; the time of administration of green tea is pivotal for effective chemoprevention. Beverage levels of green tea do not inhibit the progress of any large adenomas or adenocarcinomas existing prior to the tea administration.

RESUMEN

Synthetic oligonucleotides with a fluorescent coumarin group replacing a basepair have been used in recent time-resolved Stokes-shift experiments to measure DNA dynamics on the femtosecond to nanosecond timescales. Here, we show that the APE1 endonuclease cleaves such a modified oligonucleotide at the abasic site opposite the coumarin with only a fourfold reduction in rate. In addition, a noncatalytic mutant (D210N) binds tightly to the same oligonucleotide, albeit with an 85-fold reduction in binding constant relative to a native oligonucleotide containing a guanine opposite the abasic site. Thus, the modified oligonucleotide retains substantial biological activity and serves as a useful model of native DNA. In the complex of the coumarin-containing oligonucleotide and the noncatalytic APE1, the dye's absorption spectrum is shifted relative to its spectrum in either water or within the unbound oligonucleotide. Thus the dye occupies a site within the DNA:protein complex. This result is consistent with modeling, which shows that the complex accommodates coumarin at the site of the orphaned base with little distortion of the native structure. Stokes-shift measurements of the complex show surprisingly little change in the dynamics within the 40 ps-40 ns time range.
