Antiplatelet agents'-ticagrelol and eptifibatide-safety in experimental colitis in mice.

BACKGROUND/AIMS: To evaluate the side effects of two antiplatelet agents - ticagrelor and eptifibatide - in mice with experimentally-induced inflammatory bowel disease. METHODS AND MATERIAL: This study was designed as a controlled, animal, drug safety investigation. C57Bl/6 mice were used to establish the ulcerative colitis model by exposure to dextran sulfate sodium (DSS), and divided into three experimental groups: eptifibatide-treated (150 µg/day intraperitoneally; n = 10), ticagrelol-treated (1 mg/day via gastric tube; n = 10), and DSS-control (plain drinking water; n = 10). An unmodeled non-DSS group served as the experimental control. Complete blood count was taken for all mice at baseline (day 0, treatment initiation) and after four days of treatment. On day 4, all animals were sacrificed for autopsy. The primary outcome measure was bleeding, and the secondary outcomes were change in platelet count, hemoglobin level, and hematocrit level. RESULTS: Neither ticagrelor nor eptifibatide treatment produced a significant effect on DSS colitis mice for the safety parameters measured. Platelet count and hemoglobin and hematocrit levels were statistically similar between the three DSS groups and the non-DSS control group (P > 0.05). Autopsy found no evidence of recent bleeding in liver, spleen, central nervous system or serous cavities. CONCLUSION: The antiplatelet agents ticagrelor and eptifibatide were safe in DSS colitis mice, suggesting their potential in humans suffering from ulcerative colitis, and supporting future safety studies.

Anesthesia for patients with psychiatric illnesses: a narrative review with emphasis on preoperative assessment and postoperative recovery and pain.

The physical and psychological fragility of patients with psychiatric illness poses critical importance in the preoperative assessment, evaluation, and choice of premedication, which includes regular therapy, as well as concerns about polypharmacy with possible interactions of anesthetics, analgesics, and psychiatric medications. A considerable effort is to reduce risks for exacerbations or relapses of imminent illness in the postoperative period. In this narrative review, the goal was also set towards the use of proper tools for the preoperative assessment of anxiety and management of postoperative pain. Indeed anxiety can be a manifestation of primary comorbidity within the spectrum of a major psychiatric condition and affects dramatically the presentations of other symptoms as well evolution. Pain perception is changed in patients with psychiatric illness; therefore, the postoperative bundle of measures including assessment of pain using tools adjusted to the patient's cognitive state and regular nonopioid analgesics is important aiming to minimize opioid use. Ketamine, esketamine, xenon, nitrous oxide, dexmedetomidine, and propofol seem to have a novel role and benefit the management of certain types of psychiatric illness during the perioperative period. Psychiatrist involvement is necessary throughout the perioperative period, starting preoperatively and continuing after discharge. Clinical pharmacologists should be part of the team during the management of critically ill patients when polypharmacy can cause undesirable effects. Psychosocial wellbeing of surgical patients with psychiatric co-morbidity depends deeply on the collaboration of medical staff, family, and friends and international guidelines aim to establish standards, including but not limited to postoperative management.

Preoperative anxiety and implications on postoperative recovery: what can we do to change our history.

Preoperative anxiety can influence the intensity of postoperative pain and anesthesia and analgesia requirement. In certain types of surgery, anxiety may even increase postoperative morbidity and mortality. The goal of this narrative review is to remind anesthesiologists that anxiety measurement using specific tools can be done in clinical practice, to present the implications of preoperative anxiety on postoperative patient recovery, and to acknowledge the importance of a dedicated anesthesia plan in the management of anxious adult patients. Preoperative assessment performed several weeks before surgery in an outpatient clinic is a reasonable option to give information about surgery, anesthesia and postoperative pain. This is the time to assess patient preoperative anxiety by using VAS-A. If high anxiety level is detected early, the patient can be referred to a psychologist for preoperative preparation. This is consistent with the guidelines for enhanced recovery after surgeries, which underline the importance of patient-doctor discussion about hospitalization and perioperative care. Patients with preoperative anxiety could benefit from multimodal analgesia, including non-pharmacological methods, such as cognitive therapy and music therapy and relaxation. The authors' opinion is that greater education about preoperative anxiety consequences in the surgical community is needed. A systemized approach and guidelines about the management of preoperative anxiety should be followed.

Cross-sectional survey on complementary and alternative medicine awareness among health care professionals and students using CHBQ questionnaire in a Balkan country.

OBJECTIVE: To conduct a study on attitudes, knowledge, and use of complementary and alternative medicine (CAM) therapies in Serbia. Available data about CAM therapies in the region are scarce, opinions lacking from health sector. Balkan region countries had a delay in issuing national policies on CAM therapies. METHODS: The questionnaire used was based on previously validated CAM Health Belief Questionnaire (CHBQ), formulated as 5-item Likert type scale, adjusted for local environment. Health care students and professionals were evaluated. The questionnaire comprehended 10 closed questions on attitudes, knowledge and use of CAM therapies. This survey was conducted in eight cities of Serbia, January 2010-July 2011. A total of 797 participants was included. The second group of participants was 145 healthcare professionals (50 academic staff, 64 clinical staff, 19 pharmacists, 6 other clinical branch specialists and 6 nurses). Data were collected by an interview. Examinees could acquire maximum of 70 points, 35 representing neutral attitude. RESULTS: Students of dentistry (54.65±6.07) were better informed on CAM therapies than medicine students (50.26±7.92). Pharmacy students (51.16±7.10) accepted low-scientific CAM. Pharmacists scored better than university professors (55.12±6.55 vs. 50.29±9.50). Primary health care professionals had better awareness than pharmacists in dispensing pharmacies. Both groups of participants preferred use of vitamins over any other CAM therapy. CONCLUSION: These pioneering efforts in the region exposed weaknesses in CAM attitudes of current and future health care professionals. Nevertheless, awareness on alternative medicine treatment choices is growing among Balkan prescribers. Supportive legal framework would facilitate dissemination of CAM medical practices.
