Students' perception of online learning during the COVID-19 pandemic: A survey study of Polish medical students.

ABSTRACT: The COVID-19 pandemic has disrupted teaching in a variety of institutions, especially in medical schools. Electronic learning (e-learning) became the core method of teaching the curriculum during the pandemic. After 8 weeks of only online learning, a survey was conducted to investigate perception of this type of learning among medical students.A survey was conducted by distributing an online questionnaire to Polish medical students. Data gathered from the survey were analyzed with routine statistical software.Eight hundred four students answered the questionnaire. According to respondents' answers, the main advantages of online learning were the ability to stay at home (69%), continuous access to online materials (69%), learning at your own pace (64%), and comfortable surroundings (54%). The majority of respondents chose lack of interactions with patients (70%) and technical problems with IT equipment (54%) as the main disadvantages. There was no statistical difference between face-to-face and online learning in terms of opinions on the ability of the learning method to increase knowledge (P = .46). E-learning was considered less effective than face-to-face learning in terms of increasing skills (P < .001) and social competences (P < .001). Students assessed that they were less active during online classes compared to traditional classes (P < .001). E-learning was rated as enjoyable by 73% of respondents.E-learning is a powerful tool for teaching medical students. However, successful implementation of online learning into the curriculum requires a well thought-out strategy and a more active approach.

A subjective sense of the quality of life in adolescents from the Swietokrzyskie Voivodship.

OBJECTIVES: The measurement of the health-related quality of life (HRQOL) is one of the most important methods for self-assessment of health, which makes it possible to identify irregularities in the physical, mental and social functioning. The aim of the research was to determine HRQOL using the Health Related Quality of Life Questionnaire for Children and Young People (the KIDSCREEN-52 questionnaire) - the instrument recommended by the World Health Organization - which makes it possible to distinguish groups of adolescents with a diversified subjective sense of the quality of life. MATERIAL AND METHODS: The study involved a group of 871 adolescents, 411 boys and 460 girls, aged 13-16 years, residing in the Swietokrzyskie Voivodship. The method of a diagnostic survey was used in the research. The KIDSCREEN-52 questionnaire, which is an instrument for examining the HRQOL of adolescents, was employed in the study. The k-means clustering method was applied, which made it possible to establish 3 groups of adolescents with a different subjective sense of the quality of life. RESULTS: Three groups of adolescents with a diversified subjective sense of the quality of life (high, average, low) were identified using the KIDSCREEN-52 questionnaire. The subjective quality of life in the majority of the respondents was high, in particular in those living in rural areas. The surveyed boys with a high subjective quality of life showed a significantly higher self-esteem, acceptance and peer support than the surveyed girls. CONCLUSIONS: The KIDSCREEN-52 questionnaire is an accurate and sensitive tool for assessing HRQOL. It allows identifying 3 groups of adolescents with a diversified subjective sense of the quality of life. It can form the basis for further diagnosis of the bio-psycho-social functioning of adolescents. Int J Occup Med Environ Health. 2021;34(3):415-25.

A Non-randomized Controlled Trial of EMDR on Affective Symptoms in Patients With Glioblastoma Multiforme.

Glioblastoma multiforme (GBM) is a highly aggressive brain cancer and its survival after diagnosis is less than 2 years. Therefore, GBM patients are especially prone to co-occurring psychological conditions such as anxiety and depressive disorders. Furthermore, aggressive medical therapies affect patients' lives, undermining their sense of meaning and coherence. The main aim of this study was to determine the effectiveness of Eye Movement Desensitization and Reprocessing (EMDR) therapy on anxiety, depression and sense of coherence in patients with GBM. Thirty-seven GBM-diagnosed women were included in this trial and received standard medical care. Of those, 18 patients were treated during 4 months with 10-12 individual EMDR sessions (60-90 minutes each). Nineteen GBM patients were used as a non-randomized control group as they consented to psychological evaluations but not to a psychotherapeutic intervention. The groups were homogeneous in terms of gender, age, educational level and treatment, but not in anxiety and depressive levels at baseline. All patients were evaluated at baseline, after treatment (4 months) and at follow-up (further 4 months) by the Hospital Anxiety and Depression Scale (HADS-M) and the Sense of Coherence Scale (SOC-29). Caregivers in both groups were interviewed by the Patient Caregiver Questionnaire after 4 months follow-up. Statistical analyses were conducted using ANOVA statistics, correlation and regression analysis. Results showed a statistically significant decrease in the EMDR group in anxiety, depression and anger, when compared to the experimental group. EMDR therapy also had a positive impact upon the sense of coherence level in the experimental group, whereas in the control group this declined. Finally, the caregivers reported beneficial outcomes of the EMDR therapy with less anxiety- and anger-related behaviors in patients in the experimental group compared to the control group. This study is the first to show beneficial effects of EMDR therapy in alleviating affective symptoms and improving coherence in a severe medically ill population with GBM.

Combination of phenobarbital with phenytoin and pregabalin produces synergy in the mouse tonic-clonic seizure model: An isobolographic analysis.

AIMS: Despite many antiepileptic drugs (AEDs) are available to treat epilepsy, there is still about 30% of epilepsy patients inadequately treated with these AEDs. For these patients, polytherapy with two or three AEDs to fully control their seizure attacks is recommended. Unfortunately, polytherapy is always associated with drug interactions, whose nature may be beneficial, neutral or unfavorable. To determine a type of interaction for the combination of three AEDs (i.e., phenobarbital [PB], phenytoin [PHT] and pregabalin [PGB]) at the fixed-ratio of 1:1:1, we used a model of tonic-clonic seizures in male albino Swiss mice. MATERIALS AND METHOD: Tonic-clonic seizures in mice were evoked by a current (sine-wave, 25 mA, 500 V, 0.2 s stimulus duration) delivered via auricular electrodes. The anticonvulsant effects of the three-drug combination (PB, PHT and PGB) in terms of suppression of tonic-clonic seizures in mice were assessed with type I isobolographic analysis. Potential acute side effects for the mixture of PB, PHT and PGB along with total brain concentrations of the AEDs were determined to confirm pharmacodynamic nature of observed interaction. RESULTS: The three-drug combination of PB, PHT and PGB (at the fixed-ratio of 1:1:1) exerted synergistic interaction (at P < 0.01) in the mouse model of tonic-clonic seizures. The combination of PB, PHT and PGB did not produce any side effects in experimental animals, when measuring long-term memory, muscular strength and motor coordination. The measurement of total brain concentrations of PB, PHT and PGB was conducted to confirm that none of the three AEDs significantly influenced total brain concentrations (pharmacokinetic profiles) of the other co-administered AEDs in mice. CONCLUSIONS: The synergistic pharmacodynamic interaction for the combination of PB, PHT and PGB observed in this preclinical study can be translated into clinical settings and this favorable AED combination is worthy of being recommended to some patients with refractory epilepsy.

Effects of arachidonyl-2'-chloroethylamide (ACEA) on the protective action of various antiepileptic drugs in the 6-Hz corneal stimulation model in mice.

Accumulating evidence indicates that cannabinoid CB1 receptor ligands play a pivotal role in seizures, not only in preclinical studies on animals, but also in clinical settings. This study was aimed at characterizing the influence of arachidonyl-2'-chloroethylamide (ACEA-a selective cannabinoid CB1 receptor agonist) co-administered with phenylmethylsulfonyl fluoride (PMSF) on the anticonvulsant potency of various antiepileptic drugs (clobazam, lacosamide, levetiracetam, phenobarbital, tiagabine and valproate) in the 6-Hz corneal stimulation model. Psychomotor seizures in male albino Swiss mice were evoked by a current (32 mA, 6 Hz, 3 s stimulus duration) delivered via corneal electrodes. Potential adverse effects produced by the antiepileptic drugs in combination with ACEA+PMSF were assessed using the chimney test (motor performance), passive avoidance task (remembering and acquisition of learning), and grip-strength test (muscular strength). Brain concentrations of antiepileptic drugs were measured by HPLC to exclude any pharmacokinetic contribution to the observed effect. ACEA (5 mg/kg, i.p.) + PMSF (30 mg/kg, i.p.) significantly potentiated the anticonvulsant potency of levetiracetam (P<0.05), but not that of clobazam, lacosamide, phenobarbital, tiagabine or valproate in the 6-Hz corneal stimulation model. Moreover, ACEA+PMSF did not significantly affect total brain concentrations of levetiracetam in mice. No behavioral side effects were observed in animals receiving combinations of the studied antiepileptic drugs with ACEA+PMSF. In conclusion, the combined administration of ACEA+PMSF with levetiracetam is associated with beneficial anticonvulsant pharmacodynamic interaction in the 6-Hz corneal stimulation model. The selective activation of cannabinoid CB1 receptor-mediated neurotransmission in the brain may enhance levetiracetam-related suppression of seizures in epilepsy patients, contributing to the efficacious treatment of epilepsy in future.

Ivabradine attenuates the anticonvulsant potency of lamotrigine, but not that of lacosamide, pregabalin and topiramate in the tonic-clonic seizure model in mice.

Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels are involved not only in synaptic transmission and neuronal excitability under physiological conditions, but also in seizure activity. To determine the influence of ivabradine (an HCN channel inhibitor) on the anticonvulsant potency of four novel antiepileptic drugs (AEDs: lacosamide, lamotrigine, pregabalin and topiramate) in the mouse maximal electroshock-induced seizure (MES) model. Adult male albino Swiss mice were challenged with maximal electroconvulsions (electric current of 25mA delivered via auricular electrodes). Total brain concentrations of AEDs were measured with high-pressure liquid chromatography. Ivabradine (10mg/kg, i.p.) significantly reduced the anticonvulsant potency of lamotrigine by elevating the ED50 value of the AED from 7.48 (6.15-9.11) to 10.07 (8.85-11.45) mg/kg (P<0.05) in the mouse MES model. In contrast, ivabradine (10mg/kg, i.p.) did not significantly affect the anticonvulsant potency of lacosamide, pregabalin or topiramate in the mouse MES model. Additionally, ivabradine had no impact on total brain concentrations of all the studied AEDs in mice. A special caution is advised when combining ivabradine with lamotrigine in epilepsy patients due to the possible pharmacodynamic reduction of the anticonvulsant action of the later drug. The combinations of ivabradine with lacosamide, pregabalin and topiramate seem to be pharmacodynamic and neutral from a preclinical viewpoint.

Influence of Ivabradine on the Anticonvulsant Action of Four Classical Antiepileptic Drugs Against Maximal Electroshock-Induced Seizures in Mice.

Although the role of hyperpolarization-activated cyclic nucleotide-gated (HCN) channels in neuronal excitability and synaptic transmission is still unclear, it is postulated that the HCN channels may be involved in seizure activity. The aim of this study was to assess the effects of ivabradine (an HCN channel inhibitor) on the protective action of four classical antiepileptic drugs (carbamazepine, phenobarbital, phenytoin and valproate) against maximal electroshock-induced seizures in mice. Tonic seizures (maximal electroconvulsions) were evoked in adult male albino Swiss mice by an electric current (sine-wave, 25 mA, 0.2 s stimulus duration) delivered via auricular electrodes. Acute adverse-effect profiles of the combinations of ivabradine with classical antiepileptic drugs were measured in mice along with total brain antiepileptic drug concentrations. Results indicate that ivabradine (10 mg/kg, i.p.) significantly enhanced the anticonvulsant activity of valproate and considerably reduced that of phenytoin in the mouse maximal electroshock-induced seizure model. Ivabradine (10 mg/kg) had no impact on the anticonvulsant potency of carbamazepine and phenobarbital in the maximal electroshock-induced seizure test in mice. Ivabradine (10 mg/kg) significantly diminished total brain concentration of phenytoin and had no effect on total brain valproate concentration in mice. In conclusion, the enhanced anticonvulsant action of valproate by ivabradine in the mouse maximal electroshock-induced seizure model was pharmacodynamic in nature. A special attention is required when combining ivabradine with phenytoin due to a pharmacokinetic interaction and reduction of the anticonvulsant action of phenytoin in mice. The combinations of ivabradine with carbamazepine and phenobarbital were neutral from a preclinical viewpoint.

Influence of xanthotoxin (8-methoxypsoralen) on the anticonvulsant activity of various novel antiepileptic drugs against maximal electroshock-induced seizures in mice.

The aim of this study was to determine the effects of xanthotoxin (8-methoxypsoralen) on the protective action of 5 various second- and third-generation antiepileptic drugs (i.e., lacosamide, lamotrigine, oxcarbazepine, pregabalin and topiramate) in the mouse maximal electroshock-induced seizure model. Seizure activity was evoked in adult male albino Swiss mice by a current (25mA, 500V, 0.2s stimulus duration) delivered via auricular electrodes. Drug-related adverse effects were determined in the chimney, grip-strength and passive avoidance tests. Total brain antiepileptic drug concentrations were measured to confirm pharmacodynamic nature of observed interactions with xanthotoxin. Results indicate that xanthotoxin (100mg/kg, i.p.) significantly enhanced the anticonvulsant action of lacosamide (P<0.01), oxcarbazepine (P<0.05), pregabalin (P<0.01), and topiramate (P<0.001), but not that of lamotrigine in the maximal electroshock-induced seizure test. Moreover, xanthotoxin (50mg/kg) still significantly potentiated the anticonvulsant action of lacosamide (P<0.05), pregabalin (P<0.05), and topiramate (P<0.001) in this seizure test. Xanthotoxin had no significant impact on total brain concentrations of the studied antiepileptic drugs in mice. Furthermore, combinations of xanthotoxin with oxcarbazepine or topiramate produced no adverse effects. However, xanthotoxin in combination with lacosamide, lamotrigine or pregabalin significantly reduced muscular strength in mice in the grip-strength test. In the chimney test, only the combinations of xanthotoxin with pregabalin significantly impaired motor coordination in mice. In conclusion, the combinations of xanthotoxin with oxcarbazepine and topiramate produce beneficial anticonvulsant pharmacodynamic interactions in the maximal electroshock-induced seizure test. A special caution is advised when combining xanthotoxin with pregabalin due to appearance of acute adverse effects.

Single centre 20 year survey of antiepileptic drug-induced hypersensitivity reactions.

BACKGROUND: Epilepsy is a chronic neurological disease which affects about 1% of the human population. There are 50 million patients in the world suffering from this disease and 2 million new cases per year are observed. The necessary treatment with antiepileptic drugs (AEDs) increases the risk of adverse reactions. In case of 15% of people receiving AEDs, cutaneous reactions, like maculopapular or erythematous pruritic rash, may appear within four weeks of initiating therapy with AEDs. METHODS: This study involved 300 epileptic patients in the period between September 1989 and September 2009. A cutaneous adverse reaction was defined as a diffuse rash, which had no other obvious reason than a drug effect, and resulted in contacting a physician. RESULTS: Among 300 epileptic patients of Neurological Practice in Kielce (132 males and 168 females), a skin reaction to at least one AED was found in 30 patients. As much as 95% of the reactions occurred during therapies with carbamazepine, phenytoin, lamotrigine or oxcarbazepine. One of the patients developed Stevens-Johnson syndrome. CONCLUSION: Some hypersensitivity problems of epileptic patients were obviously related to antiepileptic treatment. Among AEDs, gabapentin, topiramate, levetiracetam, vigabatrin, and phenobarbital were not associated with skin lesions, although the number of patients in the case of the latter was small.

[Addiction prevention programs in schools and welfare-educational institutions]. / Promocja profilaktyki uzaleznien w szkolach i placówkach opiekunczo-wychowawczych.

Results of research on the functioning of addictions prevention at schools, as well as in welfare-educational institutions have been presented in the study. The survey covered 861 teachers and form tutors from institutions situated all over Poland. The results of studied documents have been also used in the analyses. During last years, systematic growth of social pathology among groups of children and school children has been observed. Pathologies of family life are considered to be the main reason. 79.2% of those participating in the survey bear it out. Negative influence of violence in programmes presented in mass media appears to be another reason (23.7%). As many as 68.1% of being surveyed point to other causes: among them demoralizing influence of a place of residence, acquaintances, lack of possibilities to spend leisure time. A huge role in averting the social pathology growth is attributed to prevention, also to prevention carried out at schools. 35.7% of those under the survey think that prevention is carried out at Polish schools. However, its efficiency is low because it is done on irregular basis, mainly during so called weekly class meetings. In practice, programme contents included in different subjects are used to the limited extent during prevention actions. Thus, there appears an urgent need to promote prevention programmes designed by central, provincial and council institutions, as well as schools.
