Knowledge, attitudes, and practice with respect to antibiotic use among pharmacy students: a cross-sectional study.

OBJECTIVE: Antibiotic resistance is a major health threat and efforts should be intensified to reduce its burden. Healthcare providers, especially pharmacists, can be actively involved in the reduction of antibiotic resistance. However, negative practices among pharmacists have been observed. This study evaluated knowledge, attitudes, and practices (KAP) among Jordanian pharmacy students. PATIENTS AND METHODS: A cross-sectional study used an online questionnaire that was developed and distributed to Jordanian pharmacy students from five different universities. KAP scores were calculated, with students categorized into low and high levels based on each score mean. RESULTS: A total of 890 pharmacy students completed the questionnaire. High positive response rate (PR%) for the majority of the knowledge items was observed, exceeding 60% in all knowledge items, and similar PR% was observed in attitude items. The variables significantly associated with attitude were age [OR=0.92 (95% CI 0.87: 0.98), p=0.01] and knowledge [OR=1.35 (95% CI 1.01:1.82), p=0.04], while knowledge was significantly associated with practice [OR=0.23 (95% CI 0.16:0.31), p<0.001]. CONCLUSIONS: Jordanian pharmacy students showed adequate KAP toward the use of antibiotics although several aspects of malpractice were identified. Hence, adequate knowledge about antibiotics among pharmacy students should be ensured as knowledge is associated with attitudes and practices.

Ceftriaxone Reduces Waterpipe Tobacco Smoke Withdrawal-induced Anxiety in rats via Modulating the Expression of TNF-α/NFĸB, Nrf2, and GLT-1.

Tobacco exposure has been linked to neuroinflammation and adaptive/maladaptive changes in neurotransmitter systems, including in glutamatergic systems. We examined the effects of waterpipe tobacco smoke (WTS) on inflammatory mediators and astroglial glutamate transporters in mesocorticolimbic brain regions including the prefrontal cortex (PFC), nucleus accumbens (NAc) and ventral tegmental area (VTA). The behavioral consequences of WTS exposure on withdrawal-induced anxiety-like behavior were assessed using elevated plus maze (EPM) and open field (OF) tests. Male Sprague-Dawley rats were randomly assigned to 3 experimental groups: a control group exposed only to standard room air, a WTS exposed group treated with saline vehicle, and a WTS exposed group treated with ceftriaxone. WTS exposure was performed for 2 h/day, 5 days/week, for 4 weeks. Behavioral tests (EPM and OF) were conducted weekly 24 h after WTS exposure, during acute withdrawal. During week 4, rats were given either saline or ceftriaxone (200 mg/kg i.p.) 30 min before WTS exposure. WTS increased withdrawal-induced anxiety, and ceftriaxone attenuated this effect. WTS exposure increased the relative mRNA levels for nuclear factor ĸB (NFĸB), tumor necrosis factor-α (TNF-α), and brain-derived neurotrophic factor (BDNF) in the PFC, NAc and VTA, and ceftriaxone treatment reversed these effects. In addition, WTS decreased the relative mRNA of nuclear factor erythroid 2 related factor 2 (Nrf2), glutamate transporter 1 (GLT-1) and cystine-glutamate transporter (xCT) in PFC, NAc and VTA, and ceftriaxone treatment normalized their expression. WTS caused neuroinflammation, alteration in relative mRNA glutamate transport expression, and increased anxiety-like behavior, and these effects were attenuated by ceftriaxone treatment.
