The aim of the study was to assess the effects of therapeutic ultrasound (US) on oxidative stress (OS)-induced changes in cultured human chondrocytes (HCH). For this, monolayer HCH were randomized in ...three groups: a control group (CG), a group exposed to OS (OS group), and a group exposed to US and OS (US-OS group). US exposure of the chondrocytes was performed prior to OS induction by hydrogen peroxide. Transmission electron microscopy (TEM) was used to assess the chondrocytes ultrastructure. OS and inflammatory markers were recorded. Malondialdehyde (MDA) and tumor necrosis factor (TNF)-α were significantly higher (p < 0.05) in the OS group than in CG. In the US-OS group MDA and TNF-α were significantly lower (p < 0.05) than in the OS group. Finally, in the US-OS group MDA and TNF-α were lower than in CG, but without statistical significance. TEM showed normal chondrocytes in CG. In the OS group TEM showed necrotic chondrocytes and chondrocytes with a high degree of vacuolation and cell organelles damages. In the US-OS group the chondrocytes ultrastructure was well preserved, and autophagosomes were generated. In conclusion, US could protect chondrocytes from biochemical (lipid peroxidation, inflammatory markers synthesis) and ultrastructural changes induced by OS and could stimulate autophagosomes development.
This article investigates the determinants of the intention to migrate of nursing students at a major medical university in Romania and relates them to major international developments, specifically ...the Brexit referendum and the COVID-19 pandemic.
An online survey about the intention to migrate was made available to nursing students at the University of Medicine and Pharmacy "Iuliu Hațieganu", Cluj-Napoca, Romania, in 2016 (before Brexit) and again in 2016 (after Brexit), 2017, 2018, and 2021 and 2022 (during the pandemic). A total of 549 students responded (response rate: 84.6%).
Before the Brexit referendum, 62.6% of the respondents had a plan to seek employment abroad, whereas after the Brexit referendum, only 34.7% indicated that they had such a plan after graduation. Before the pandemic, 43.6% of the students expressed an intention to work abroad, while during the pandemic, only 19.8% had such plans.
This study documented the effect of significant international developments-such as the Brexit referendum and the COVID-19 pandemic-on decreasing the intention to migrate. As expected, the change in preference for the UK as a destination country changed dramatically. Additionally, the study provides both theoretical and empirical insights into the types of and the consistency of preparation for migration of nursing students.
Osteoarthritis (OA) is the most prevalent chronic joint disease, increases in prevalence with age, and affects most individuals over 65. The present study aimed to assess the oxidative status in ...relation to diet and physical activity in patients with OA. We used a cross-sectional study applied to 98 females with OA. Blood samples were collected to determine oxidative stress markers: malonyl dialdehyde (MDA), reduced glutathione (GSH), oxidized glutathione (GSSG), and GSH/GSSG. Diet was estimated with a standardized food frequency questionnaire. We used the International Physical Activity Questionnaire (IPAQ) to assess the females’ physical activity. Multiple regression analyses were executed to determine the association between the oxidative markers and the intake of vegetables and fruit. The study showed that most patients were overweight or obese (88.8%). The level of physical activity was above the recommended level for adults, mainly based on household activities. The intake of vegetables and fruit was low. The MDA marker was inversely, statistically significantly associated with the consumption of vegetables (p < 0.05). Public health policies must address modifiable risk factors to reduce energy intake and obesity and increase the intake of vegetables and fruit. Higher consumption of vegetables and fruit may provide natural antioxidants that can balance oxidative compounds.
Background and Objectives: The ongoing COVID-19 pandemic has posed an array of new challenges for medical students worldwide. Amidst academic rigors, students are confronted with unique stressors, ...potentially affecting their mental health and substance use. This study aimed to investigate the multifaceted effects of depression, alcohol use, and stress on medical students and discern how these factors have been amplified by the pandemic’s circumstances, and to identify predictors of mental distress during the COVID-19 pandemic period. Materials and Methods: Two online anonymous and cross-sectional surveys were conducted at the University of Medicine and Pharmacy “Iuliu Hatieganu” in Romania among medical students in 2018 and in 2022. Data were gathered via online questionnaires distributed through closed student groups on social media platforms, with a total of 1061 participants, to investigate stress, depression, alcohol and drug use, and the impact of the pandemic and online education on mental health, maintaining anonymity and ethical approval. The Medical Student Stress Questionnaire (MSSQ) was employed to measure different aspects of stress, the Beck Depression Inventory (BDI) provided insights into the participants’ depressive symptoms, and for the assessment of alcohol consumption habits, the Alcohol Use Disorders Identification Test (AUDIT) was utilized. Results: Our findings showed a significant decrease in mean depression scores (13.81 vs. 11.56, with p < 0.001) from 2018 to 2022. In 2018, students scored significantly higher in the overall stress-related domains. Additionally, being female, facing financial constraints, and being in pre-clinical years emerged as predictors of heightened academic-related stress and depressive symptoms. Students who had experienced the loss of a family member due to COVID-19 exhibited a statistically significant rise in their average BDI score and current anxiety levels. Conclusions: The pandemic, despite introducing new stressors, may have indirectly fostered an increased focus on students’ mental health, leading to more refined support mechanisms. Specialized interventions, taking into account gender and financial problems, are needed to address the multifaceted challenges faced by medical students. Our study highlights the ongoing need to nurture both the academic and emotional strength of future medical practitioners.
Diabetes mellitus and high-fat diets trigger the mechanisms that alter the walls of blood vessels. Gold nanoparticles, as new pharmaceutical drug delivery systems, may be used in the treatment of ...different diseases. In our study, the aorta was investigated via imaging after the oral administration of gold nanoparticles functionalized with bioactive compounds derived from
fruit extract (AuNPsCM) in rats with a high-fat diet and diabetes mellitus. Sprague Dawley female rats that received a high-fat diet (HFD) for 8 months were injected with streptozotocin to develop diabetes mellitus (DM). The rats were randomly allocated into five groups and were treated, for one additional month with HFD, with carboxymethylcellulose (CMC), insulin, pioglitazone, AuNPsCM solution or with
L. extract solution. The aorta imaging investigation consisted of echography, magnetic resonance imaging and transmission electron microscopy (TEM). Compared to the rats that received only CMC, the oral administration of AuNPsCM produced significant increases in aorta volume and significant decreases in blood flow velocity, with ultrastructural disorganization of the aorta wall. The oral administration of AuNPsCM altered the aorta wall with effects on the blood flow.
This study focuses on the assessment of attitudes and practices regarding research among undergraduate medical students from Cluj-Napoca, Romania.
A cross-sectional study was performed thorough ...anonymous questionnaires (May-June 2018) among 510 third- and fifth-year students of Iuliu Hatieganu University of Medicine and Pharmacy from Cluj-Napoca, Romania.
More than 60% of the third- and fifth-year students declared that they were interested and willing to perform research during medical studies, while more than two-thirds were interested in doing so after graduation. In total, 6% of third-year students and 31% of fifth-year students declared that they had prepared a scientific presentation for a medical congress at least once. Around 9% of the third-year students contributed to the writing of a scientific article and participated in research projects. Among fifth-year students, one-quarter were involved in writing scientific papers, and 21% participated in research projects.
To the best of our knowledge, this study assesses, for the first time in Romania, the perspectives and behaviors of medical undergraduate students with regard to involvement in research activities. The results show that Romanian medical students value opportunities for conducting research, which encourages institutional initiatives that support their involvement in curricular and extracurricular research activities.

Anatomy is an important and intense mandatory course offered during the first year of medical school. Corpse dissection is very important in Anatomy teaching, and first year students will encounter, ...most likely for the first time, a dead human body during Anatomy labs.
The purpose of this study was to evaluate the anxiety experienced by medical students with no previous corpse dissection background just before, after a week, and then after a month of dissection labs, and to investigate the relationship between students' personality and their attitude towards dissection.
138 first year English Section medical students from the "Iuliu Hatieganu" University of Medicine and Pharmacy, Cluj-Napoca, Romania, completed a personality inventory, an anxiety scale and a questionnaire to assess their attitudes and reactions to anatomical dissection.
The level of anxiety reported by students increased from before the first dissection encounter to after one month of dissection labs.
There is a relationship between the Five Factor model of personality and students' attitudes towards dissection. Medical students could be better prepared for their first corpse dissection experience if the preparation before dissection would take in consideration their psychological traits.
Stigmatizing attitudes to mental illness, and especially schizophrenia, are not limited to the general population but are also common among health professionals. Health professionals are in a ...position to model health related attitudes both in the general public and patients. Medical students are an interesting group to focus upon, since they are future health professionals and correcting stigmatizing attitudes is still possible during their educational curriculum.
This study investigated the attitude toward mental illness in medical students at the Iuliu Hatieganu University of Medicine and Pharmacy. We surveyed first year students, since they have not yet received specific classes or internships in psychiatry; 322 students from the Romanian and English sections participated, representing a response rate of 94.7%. The questionnaire consisted of the Romanian and English versions of Link's Social Distance Scale towards people with mental illness scale.
Overall, medical students had a relatively negative attitude towards people with mental illness, with moderate social distance and stereotypical attitudes. The level of personal contact with people with mental illness was correlated with positive attitudes. International students had scored lower then Romanian students on social distance toward mentally ill patients.
Medical education can play an important role in the attitudes of students toward mental illness. Medical students have stigmatizing attitudes about mentally ill patients. Personal contact with people suffering from mental illness might contribute to a positive attitude from the medical students toward mentally ill patients.
Osteoarthritis (OA) represents a public health challenge since the pathogenic treatment, able to induce cartilage regeneration, still remains unknown. Ageing of the population and increasing OA ...prevalence have led to a lot of research, aiming to identify treatments acting on chondrocytes that play a determinant role in cartilage degeneration÷regeneration balance. Pulsed shortwave therapy (with the classical application form - Diapulse) is a physiotherapy method with anabolic effects demonstrated on nervous, conjunctive and vascular tissues, but its effects on OA cartilage are not known.
Our aim was to demonstrate the effects of Diapulse on the cartilage in experimental induced OA.
Experimental OA was induced in 10 mature female rabbits by anterior cruciate ligament transection (ACLT). Ten weeks after ACLT, rabbits were randomized in a treatment group and a control group. Treatment group was exposed to Diapulse at a frequency of 27.12 MHz, pulse length of 65 μs, pulse frequency of 300 pulses÷s (300 Hz) for 10 minutes÷day. Control group was exposed to sham therapy. After treatment, rabbits were sacrificed and the cartilage was evaluated by histopathological examinations with Hematoxylin-Eosin (HE) staining and transmission electron microscopy (TEM).
OA characteristic changes were found in both groups. In the treatment group, we found that Diapulse influenced the degenerative process in the OA cartilage by improving the chondrocyte viability and the capacity to maintain cellular matrix integrity and structure.
Diapulse can be considered a disease modifying therapeutic procedure and could be a reliable option for treatment of OA patients.
