Public Knowledge, Beliefs and Behavior on Antibiotic Use and Self-Medication in Lithuania

Irrational antibiotic use has led society to antibiotic resistance—a serious health problem worldwide. This study aimed to assess public knowledge, beliefs, and behavior concerning antibiotic use and self-medication in Lithuania. The cross-sectional survey method was processed using a validated questionnaire in different regions of Lithuania. In total, 1005 adults completed the questionnaire and were included in the study. More than half of the respondents (61.1%) had poor knowledge of antibiotics. Almost half of the respondents incorrectly identified antibiotics as being effective either against viral (26.0%) or mixed (bacterial and viral) infections (21.7%). The respondents with lower educational qualifications (OR = 2.515; 95% CI 1.464–4.319; p = 0.001) and those from rural areas (OR = 1.765; 95% CI 1.041–2.991; p = 0.035) were significantly less knowledgeable of antibiotics. There was no significant difference between genders, different age groups, or different parenthood status. The determined level of self–medication with antibiotics was 31.0%. The men (OR = 1.650; 95% CI 1.120–2.430; p = 0.011), the respondents from rural areas (OR = 2.002; 95% CI 1.343–2.985; p = 0.001), and those without children (OR = 2.428; 95% CI 1.477–3.991; p < 0.001) were more likely to use antibiotics in self-medication. Lithuanian residents’ knowledge of antibiotics is insufficient. More information about antibiotic use should be provided by physicians and pharmacists. Self-medication with antibiotics is a serious problem in Lithuania and requires considerable attention.

Response inhibition, set shifting, and complex executive function in patients with chronic lower back pain

OBJECTIVE The aim of our study was to evaluate how response inhibition, set shifting, and complex executive function (represented by risky decision-making) are altered in chronic lower back pain patients. MATERIALS AND METHODS A total of 29 patients with chronic lower back pain (CLBP >6 months) aged 49-69 years and 30 healthy volunteers matched for age, gender, and education were enrolled in a case-control study. The study was conducted in the Departments of Neurology and Neurosurgery of Panevėžys Regional Hospital, Lithuania. Pain was evaluated by the visual analog scale, Pakula Pain Questionnaire (Lithuanian analog of McGill Pain Questionnaire), and Fibromyalgia Tender Points Examination. A battery of neuropsychological tests used included Stroop Test Victoria version, Trail Making Test parts A and B, and Game of Dice Task (GDT). RESULTS CLBP patients did not score significantly worse in any examined neuropsychological tests. Response Inhibition correlated inversely with number of tender points in CLBP patients. GDT performance showed no significant difference in net score (number of safe minus risky decisions). Unexpectedly, both groups favored risky decisions. CONCLUSIONS We found no statistically significant difference in response inhibition, set shifting, or complex executive function between CLBP patients and healthy older adults. Moreover, a risky decision-making pattern found in the Lithuanian population may underscore the importance of cultural context when examining complex executive function. However, further studies are needed to prove this point.

Validation of the EFFECT questionnaire for competence-based clinical teaching in residency training in Lithuania

BACKGROUND AND AIM In 2013, all residency programs at the Lithuanian University of Health Sciences were renewed into a competency-based medical education curriculum. To assess the quality of clinical teaching in residency training, we chose the EFFECT (evaluation and feedback for effective clinical teaching) questionnaire designed and validated at the Radboud University Medical Centre in the Netherlands. The aim of this study was to validate the EFFECT questionnaire for quality assessment of clinical teaching in residency training. MATERIALS AND METHODS The research was conducted as an online survey using the questionnaire containing 58 items in 7 domains. The questionnaire was double-translated into Lithuanian. It was sent to 182 residents of 7 residency programs (anesthesiology reanimathology, cardiology, dermatovenerology, emergency medicine, neurology, obstetrics and gynecology, physical medicine and rehabilitation). Overall, 333 questionnaires about 146 clinical teachers were filled in. To determine the item characteristics and internal consistency (Cronbachs α), the item and reliability analyses were performed. Furthermore, confirmatory factor analysis (CFI) was performed using a model for maximum-likelihood estimation. RESULTS Cronbachs α within different domains ranged between 0.91 and 0.97 and was comparable with the original version of the questionnaire. Confirmatory factor analysis demonstrated satisfactory model-fit with CFI of 0.841 and absolute model-fit RMSEA of 0.098. CONCLUSIONS The results suggest that the Lithuanian version of the EFFECT maintains its original validity and may serve as a valid instrument for quality assessment of clinical teaching in competency-based residency training in Lithuania.

Crucial role of carotid ultrasound for the rapid diagnosis of hyperacute aortic dissection complicated by cerebral infarction: A case report and literature review

Aortic dissection is a life-threatening rare condition that may virtually present by any organ system dysfunction, the nervous system included. Acute cerebral infarction among multiple other neurological and non-neurological presentations is part of this acute aortic syndrome. Rapid and correct diagnosis is of extreme importance keeping in mind the possibility of thrombolytic treatment if a patient with a suspected ischemic stroke arrives to the Emergency Department within a 4.5-h window after symptom onset. Systemic intravenous thrombolysis in the case of an acute brain infarction due to aortic dissection may lead to fatal outcomes. In this neurological emergency it is important to rule out underlying aortic dissection by choosing appropriately quick and accurate diagnostic tool. We aimed to present a prospective follow-up case, where carotid ultrasound examination was the primary key method that led to a correct diagnosis in hyperacute (<24h) Stanford type A aortic dissection presenting as an acute ischemic stroke, and thereafter with a repeated contrast-enhanced computed tomography and transthoracic echocardiography, helped to monitor topography of intravascular processes and hemodynamic properties during the clinical course of a disease, which influenced treatment decisions. Thus, we reviewed the literature mainly focusing on the various neurological aspects associated with aortic dissection.

Impact of the World Health Organization Pain Treatment Guidelines and the European Medicines Agency Safety Recommendations on Nonsteroidal Anti-Inflammatory Drug Use in Lithuania: An Observational Study

Background and objective: Irrational use of nonsteroidal anti-inflammatory drugs (NSAIDs) is the main cause of adverse effects-associated hospitalizations among all medication groups leading to extremely increased costs for health care. Pharmacoepidemiological studies can partly reveal such issues and encourage further decisions. Therefore, the aim of our study was to evaluate the utilization of non-opioid analgesics (ATC classification N02B and M01A) in Lithuania, and to compare it with that of other Baltic and Scandinavian countries in terms of compliance to the WHO pain treatment guidelines and the EMA safety recommendations on NSAID use. Materials and methods: The dispensing data were obtained from the sales analysis software provider in the Baltic countries (SoftDent, Ltd., Kaunas, Lithuania); State Medicine Control Agencies of Lithuania, Latvia, and Estonia; Norwegian Prescription Database; Swedish Database for Medicines; and Danish Prescription Database. Data included the utilization of both prescription and over-the-counter drugs. Utilization was expressed in defined daily doses (DDD)/1000 inhabitants/day. Results: During the 11-year period, the utilization of drugs belonging to the N02B and M01A groups increased by 22.8%, from 58.37 in 2005 to 71.68 DDD/1000 inhabitants/day in 2016 in Lithuania. Contrary to the WHO guidelines on pain management, all Baltic countries were more likely to use NSAIDs than other analgesics and antipyretics: in 2015, the drugs of the M01A group were used 6.04, 5.79, and 6.11 times more than those of N02B in Lithuania, Estonia, and Latvia, respectively, whereas the Scandinavian countries preferred the N02B to the M01A group: in Denmark and Sweden, the utilization of other analgesics and antipyretics was 2.33 and 1.24, respectively, times higher than that of NSAIDs. In Norway, the use of both groups was similar. In the Scandinavian countries, paracetamol was the analgesic of first choice, whereas, in Lithuania, it took only the third place. The most popular drug in Lithuania was diclofenac, and its utilization accounted for 30.04% of all non-opioid analgesics in 2016. Although the European Medicines Agency (EMA) restricted the use of certain NSAIDs, i.e., cyclooxygenase-2 (COX-2) inhibitors, nimesulide, and diclofenac, their use consistently increased by 15.91, 2.83, and 1.41 times, respectively, showing incompliance with the international guidelines. Conclusions: Neither the EMA safety policy on NSAID use nor the WHO pain treatment guidelines had a sufficient impact on the rational use of NSAIDs in Lithuania. The use of NSAIDs restricted by the EMA (diclofenac, COX-2 inhibitors, nimesulide, and piroxicam) remains high or even increases, while the utilization of safer alternatives (paracetamol and naproxen) remains relatively low as compared with the Scandinavian countries. Incompliance with international guidelines may result in increased morbidity, mortality and higher costs for health care.

Cognitive functions and normal tension glaucoma

Purpose: Only a few studies have analyzed the potential link between glaucoma and cognitive function impairment. They have found controversial results. This study aims to perform quick cognitive function assessment with clock drawing test (CDT) using two different scoring systems and compare between normal tension glaucoma (NTG) and cataract patients. Methods: Totally, 30 NTG and 30 patients with cataracts were included in a prospective, pilot study. The predrawn circle was given, and patients were asked to draw the clock showing a time of 11:10. The test was evaluated using two methods – Freund method using a 7-point scoring scale (optimal cutoff ≤4) and Rakusa using a 4-point scoring scale (optimal cutoff ≤3). The level of significance was set at P < 0.05. Results: CDT result was significantly better in cataract group than in NTG group: 3.5 (2) versus 2 (2) by Freund, (P = 0.003) and 6.5 (1) versus 4.5 (2.75) by Rakusa, respectively (P = 0.004). Sixty percent (n = 18) of NTG group and 10% (n = 3) of cataract group patients completed the CDT in the specific picture manner (the short hand on 11 and the long hand between 11 and 12), (P = 0.001). Conclusions: Lower CDT results were seen in NTG patients according to two different scoring systems. NTG patients showed a specific manner of drawing. Further prospective studies are needed to investigate the CDT reliability as fast screening test of cognitive function impairment in glaucoma patients.
