Personal Listening Device Use and Attitude to Noise in Relation to Depression and Anxiety among Medical Students.

Background: High levels of environmental noise may lead to psychological symptoms. The present study has hypothesized that personal listening device (PLD) use and a negative attitude to noise are significantly related to anxiety and/or depression. Methods: This is a cross-sectional study conducted on 431 six-grade students (35% male) at the Faculty of Medicine, University of Belgrade. All students completed the questionnaires related to socio-demographic data, noise/music exposure habits, behaviors related to PLD use, tinnitus, headaches, consumption of alcohol, coffee, energy drinks and cigarettes, YANS (Youth Attitude to Noise Scale), CES-D (The Center for Epidemiologic Studies Depression), and GAD-7 (Generalised Anxiety Disorder Assessment - 7 item scale) questionnaires. Results: There were 396 (91.9%) of investigated students who used PLD, with more frequent use among girls compared to boys (95.0% and 86.8%, respectively; p = 0.002). We found no significant relationship between the frequency of PLD use and depression and anxiety. However, continuous daily PLD use longer than 1 hour was significantly and positively related to depression (p = 0.006). Students with depression had a lower total YANS score compared to those without depression, indicating a more negative attitude toward noise (p = 0.042). Students with no difficulties to concentrate in noise and with a positive attitude to daily noises had about 37% lower chance to suffer from depression and anxiety, respectively. Conclusions: PLD use is common among medical students and may be associated with their mental health. Longer than 1 hour of continuous daily use of PLD may be positively related to depression. We also found a significant relationship between difficulties concentrating in noisy environments and depression, and between negative attitudes to daily noises and anxiety.

Myotonic dystrophy type 1 in the COVID-19 era.

INTRODUCTION: Myotonic dystrophy type 1 (DM1) is the most prevalent muscular dystrophy in adults. People with DM1 might represent a high-risk population for respiratory infections, including COVID-19. Our aim was to evaluate the characteristics of COVID-19 infection and vaccination rate in DM1 patients. METHODS: This cross-sectional cohort study included 89 patients from the Serbian registry for myotonic dystrophies. Mean age at testing was 48.4 ± 10.4 years with 41 (46.1%) male patients. Mean duration of the disease was 24.0 ± 10.3 years. RESULTS: COVID-19 infection was reported by 36 (40.4%) DM1 patients. Around 14% of patients had a more severe form of COVID-19 requiring hospitalization. The severity of COVID-19 was in accordance with the duration of DM1. A severe form of COVID-19 was reported in 20.8% of patients who were not vaccinated against SARS-CoV-2 and in none of the vaccinated ones. The majority of 89 tested patients (66.3%) were vaccinated against SARS-CoV-2. About half of them (54.2%) received three doses and 35.6% two doses of vaccine. Mild adverse events after vaccination were recorded in 20.3% of patients. CONCLUSIONS: The percentage of DM1 patients who suffered from COVID-19 was like in general population, but with more severe forms in DM1, especially in patients with longer DM1 duration. The study indicated an overall favorable safety profile of COVID-19 vaccines among individuals with DM1 and its ability to protect them from severe COVID-19.

Transcultural adaptation and validation of the Serbian version of the colorectal-specific quality of life questionnaire FACT-C.

OBJECTIVE: Transcultural adaptation and validation of the FACT-C questionnaire to Serbian language. METHODS: The study included 131 patients with colorectal cancer. Translation included standard forward and backward translation from original language to Serbian and back. Pilot testing of the questionnaire was conducted on 10 patients with diagnosed colorectal cancer. The questionnaires EORTC-QLQ-C30 and DASS will be used as validated tools to evaluate validity of examined, FACT-C questionnaire. RESULTS: The FACT-C demonstrated satisfactory construct validity using Cronbach's alpha. Satisfactory concurrent validity was demonstrated using correlations with EORTC-QLQ-C30 and DASS questionnaires. High reproducibility was demonstrated using repeated questionnaires on 30 patients two weeks after the first interview. CONCLUSION: The Serbian version of the FACT-C was demonstrated to have satisfactory applicability, reliability and validity in Serbian patients with colorectal cancer. It can be considered as a valid colorectal cancer specific health related quality of life tool for the Serbian population.

Long-term outcome in patients with myasthenia gravis: one decade longitudinal study.

INTRODUCTION: Even treated, myasthenia gravis (MG) continues to represent a significant burden and might continuously affect patients' quality of life (QoL). The aim of our longitudinal study was to analyze QoL in a large cohort of MG patients after a 10-year follow-up period. METHODS: This study comprised 78 MG patients (60% females, 50 ± 16 years old at baseline, 70% AchR positive) who were retested after 10 years. Disease severity was evaluated by MGFA classification. QoL was assessed using SF-36 questionnaire and Myasthenia Gravis-specific Questionnaire (MGQ). Hamilton rating scales for depression and anxiety (HDRS and HARS), Multidimensional Scale of Perceived Social Support (MSPSS) and Acceptance of Illness Scale (AIS) were also used. RESULTS: Similar percentage of patients was in remission at both time points (42% and 45%). However, at baseline all patients were treated, while 32% were treatment-free at follow-up. SF-36, MGQ, MSPSS and AIS scores were similar at baseline and retest. Mean HDRS and HARS scores worsened during time (p < 0.05), although percentage of patients with depression and anxiety did not change significantly. Significant predictors of worse SF-36 score at retest were depression (ß = - 0.45, p < 0.01), poor disease acceptance (ß = - 0.44, p < 0.01) and older age (ß = - 0.30, p < 0.01). Significant predictors of worse MGQ score at retest were poor disease acceptance (ß = - 0.40, p < 0.01), retirement (ß = - 0.36, p < 0.01), lower education (ß = 0.25, p < 0.01), and depression (ß = - 0.18, p < 0.05). CONCLUSIONS: Although after 10 years, a significant number of MG patients were in remission, their QoL was still reduced. Neurologists should be aware that patients' perception of poor QoL may persist even if MG is well treated from a physician's perspective.

Predictors of burnout among Belgrade veterinary students: A cross-sectional study.

BACKGROUND: To the best of our knowledge, studies are lacking on burnout among veterinary students in Serbia, and this is the first study trying to address such a problem. Therefore, the aim of this cross-sectional study was to investigate the predictors of burnout among Belgrade veterinary students. METHODS: Maslach Burnout Inventory (MBI) and anonymous structured questionnaire addressed to personal data, health habits and stressful influence of educational process were applied among 496 respondents from a total of 1113 students from all grades in spring semester 2014 (response rate 44.6%). RESULTS: The prevalence of burnout was 43.3%. High scores on depersonalization and emotional exhaustion scales of MBI were found among 79.4% and 45.0% students, respectively; low personal accomplishment was reported by 50.5% students. Female students reported higher levels of emotional exhaustion compared to males (p = 0.012). A low score on personal achievement scale of MBI was least frequent among the freshmen and most frequent among sophomores (41.1% and 65.3%, respectively; p = 0.986). There were more students with burnout who considered their health as a worsened vs. pre-study period compared to students with no burnout, both concerning mental (61.4% vs. 38.6%) and physical health (61.1% vs. 38.9%; both p<0.001). There were more smokers among students who suffered from burnout compared to students who did not (52.0% vs. 48.0%; p = 0.013). A multiple regression revealed an independent dose-response effect of perceived stress at exams on the onset of burnout (moderate stress OR = 2.164 and high stress OR = 3.878). Also, students with the moderate and high stressful effect of communication with teaching staff, as well as, those with worse self-perceived physical and mental health had more than two times higher presence of burnout. CONCLUSIONS: The prevalence of burnout among Belgrade veterinary students is relatively high. Primary prevention should be focused on the revealed predictors of burnout.

Impact of epilepsy duration, seizure control and EEG abnormalities on cognitive impairment in drug-resistant epilepsy patients.

Cognitive impairment frequently occurs in epilepsy patients. Patients with drug-resistant epilepsy (DRE) have poor drug responsivity and higher seizure frequency which consequently lead to brain damage and may have implications on cognitive status. In the present study, we assessed a frequency and degree of cognitive impairment in 52 patients with drug-sensitive epilepsy (DSE) and 103 DRE patients at three time points (baseline, after 12 and 18 months). Degree of cognitive decline was assessed with Montreal Cognitive Assessment (MoCA) scale. We examined the possible correlation between demographic and clinical characteristics and cognitive deterioration in epilepsy patients. Patients in the DRE group had significantly lower MoCA score than patients in the DSE group at baseline (28.83 ± 2.05 vs. 29.69 ± 0.61, p = 0.003), after 12 months (27.36 ± 2.40 vs. 29.58 ± 1.22, p = 0.000) and 18 months (26.86 ± 2.73 vs. 29.33 ± 1.47, p = 0.000). Patients with DRF epilepsy had significantly lower MoCA score than patients with DSF epilepsy at three time points (28.71 ± 2.48 vs. 29.86 ± 0.35, p = 0.015; 27.22 ± 2.72 vs. 29.52 ± 1.37, p = 0.000; 26.80 ± 2.99 vs. 29.31 ± 1.56, p = 0.000). After 12 and 18 months of follow-up, patients with DRG epilepsy had significantly lower MoCA score than patients with DSG epilepsy (27.52 ± 2.01 vs. 29.65 ± 1.02, p = 0.000; 26.94 ± 2.43 vs. 29.35 ± 1.40, p = 0.000). Illness duration negatively correlated with cognitive status (p = 0.005); seizure control and EEG findings positively correlated with MoCA score (p = 0.000). Illness duration, seizure control, drug responsivity, and EEG findings are significant predictors of MoCA score (p < 0.05). Clinicians have to pay attention to patients with drug-resistant epilepsy and concepts of aggressive treatment to minimize the adverse effects of epilepsy on cognition.
