RESUMEN

Background: Traditionally, graduates from colleges of pharmacy in Saudi Arabia work mainly in hospital settings, and only a few graduates work in other practice settings. However, several initiatives and national plans have recently been introduced to facilitate employment in community pharmacies and the pharmaceutical industry/companies. Consequently, the objectives of this study were to explore the current state of career placement, type of employment sectors, and practice settings that Doctor of Pharmacy (PharmD) graduates join based on recent developments in the profession. Methods: This study is a cross-sectional, descriptive study. The target population was PharmD graduates from Unaizah College of Pharmacy, Qassim University, Saudi Arabia. Consequently, all 162 graduates from three recent cohorts (2018-2020) were contacted to participate in this survey. Results: A total of 157 graduates participated in this study, yielding a response rate of 96.91 %. Of the participants, 92 (58.6 %) were female graduates. The overall rate of employment was 84.7 %. Moreover, a higher proportion of male graduates than female graduates (97.1 % versus 73.7 %, P = 0.006) were employed. In this study, the three main sectors that the graduates joined were the pharmaceutical industry and companies (41.2 %), community pharmacies (29.4 %), and medical cities, hospitals and clinics (23.5 %). In addition, almost the same proportions of male and female graduates joined the pharmaceutical industry and companies (40.3 % versus 42.1 %). However, a higher proportion of male graduates than female graduates joined community pharmacies (32.3 % versus 26.3 %). Conversely, a higher proportion of female graduates joined medical cities, hospitals and clinics compared to male graduates (28.1 % versus 19.4 %). Conclusion: The current employment of PharmD graduates in the job market is generally high, but further improvement could be made, especially for female graduates. Moreover, the study findings showed that jobs are shifting toward community pharmacies and the pharmaceutical industry. Therefore, we believe that decision-makers in pharmacy education and curriculum developers must consider these trends and ensure that there is adequate preparation for careers in community pharmacy practice and other sectors of the profession in the curriculum.

RESUMEN

Lambda-cyhalothrin (LTC) is a synthetic pyrethroid with a broad spectrum of insecticidal and acaricidal activities used to control a wide range of insect pests in a variety of applications. However, there is little known about its adverse effects, in particular those related to its genotoxicity in humans. To elucidate the genotoxicity mechanisms of LTC, the micronuclei (MN) frequencies, the levels of reactive oxygen species (ROS), erythrocyte osmotic fragility, nitrite (NO) formation, protein carbonyl (PCO) levels and malondialdehyde (MDA) production were evaluated for a period of 7, 14 and 21 days. Our results show that exposure rat to LTC (1/10DL50 = 6.23 mg/kg) for a period of 7, 14 and 21 days induced a noticeable genotoxic effect in rat peripheral blood evidenced by a significant increase in the frequency of MN only at day 21 of treatment. Significant differences between the two groups were observed in erythrocyte osmotic fragility. Further, a significant (p < 0.01) increase in ROS contents, NO formation, PCO levels and lipid peroxidation in erythrocytes were observed at different times of treatments, suggesting the implication of oxidative stress in its toxicity. These results confirm the genotoxic and the pro-oxidant effects of LTC in rat peripheral blood.

RESUMEN

The present study was carried out to examine the adverse hematotoxic and genotoxic effects of water nitrate pollution on male adult rats and the use of hyparrhenia hirta methanolic extract in alleviating these effects. Sodium nitrate (NaNO3 ) was administered to adult rats by oral gavage at a dose of 400 mg kg(-1) bw daily for 50 days, while hyparrhenia hirta methanolic extract was given by drinking water at a dose of 1.5 mg mL(-1) (200 mg kg(-1) bw). The NaNO3 -treated group showed a significant decrease in red blood cell count, hemoglobin and hematocrit and a significant increase in total white blood cell, in neutrophil and eosinophil counts. Platelet count, mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration remained unchanged in treated groups compared to those of controls. Meanwhile, the results showed a marked reduction in the antioxidant enzyme activities, such as superoxide dismutase, catalase, and glutathione peroxidase, along with an elevation in the level of lipid peroxidation and a reduction in the total glutathione content, indicating the induction of oxidative stress in the erythrocytes of NaNO3 -treated group. Interestingly, NaNO3 treatment showed a significant increase in the frequencies of total chromosomal aberrations, aberrant metaphases and micronucleus in bone-marrow cells. The oxidative stress induced by nitrate treatment might be the major cause for chromosomal rearrangements as free radicals leading to DNA damage. Hyparrhenia hirta methanolic extract appeared to be effective against hematotoxic and genotoxic changes induced by nitrate, as evidenced by the improvement of the markers cited above.

RESUMEN

OBJECTIVE: The present study investigated the protective role of Hyparrhenia hirta (H. hirta) against sodium nitrate (NaNO3)-induced hepatoxicity. METHODS: Male Wistar rats were randomly divided into three groups: a control group and two treated groups during 50 d with NaNO3 administered either alone in drinking water or co-administered with H. hirta. RESULTS: NaNO3 treatment induced a significant increase in serum levels of glucose, total cholesterol and triglyceride while serum total protein level decreased significantly. Transaminases and lactate deshydrogenase activities in serum were elevated indicating hepatic cells' damage after treatment with NaNO3. The hyperbilirubinemia and the increased serum gamma glutamyl transferase activities suggested the presence of cholestasis in NaNO3 exposed rats. In parallel, a significant increase in malondialdehyde level along with a concomitant decrease in total glutathione content and superoxide dismutase, catalase and glutathione peroxidase activities were observed in the liver after NaNO3 treatment. Furthermore, nitrate caused a significant induction of DNA fragmentation. These modifications in NaNO3-treated rats corresponded histologically with hepatocellular necrosis and mononuclear cells infiltration. H. hirta supplementation showed a remarkable amelioration of the abnormalities cited above. CONCLUSION: The results concluded that the treatment with H. hirta had a significant role in protecting the animals from nitrate-induced liver dysfunction.

RESUMEN

The genetic polymorphisms in DNA repair genes might affect the repair activities of the enzymes, predisposing individuals to cancer risk. Due to these genetic variants, interethnic differences in DNA repair capacity were observed in various populations. Hence, our study aimed to determine the prevalence of three nonsynonymous single-nucleotide polymorphisms (SNPs) in an X-ray repair cross-complementation group 1 gene (XRCC1) (Arg194Trp, Arg280His, and Arg399Gln) in a healthy Tunisian population (TUN) and to compare that with HapMap ( www.hapmap.org ) populations. Also, we predicted their eventual functional effect based on the protein conservation analysis by Sorting Intolerant From Tolerant (SIFT; http://sift.jcvi.org/www/SIFT_dbSNP.html ) software. The genotypes of 154 healthy individuals were determined by the polymerase chain reaction-restriction fragment length polymorphism. Tunisians showed a relative relatedness with Caucasians (European ancestry) for Arg194Trp and Arg399Gln that may be explained by the strategic geographic location of Tunisia in the Mediterranean, allowing exchanges with European countries. However, a characteristic pattern was observed in Arg280His polymorphism, which could be explained by the high inbreeding rate in TUN. The analysis of protein conservation showed that the three amino acid substitutions were predicted as damaged. The results presented here provide the first report on XRCC1 polymorphisms about Tunisians and may establish baseline database for our future clinical and genetic studies.
