Medical student´s motivational changes during the COVID-19 university lockdown: a mixed-method study.

BACKGROUND: During the crucial stage of the COVID-19 pandemic, face-to-face undergraduate medical education was disrupted and replaced with online teaching activities. Based on its emphasized impact on several outcomes, a deeper insight into the pandemic related effects on medical students´ motivation is aspirational. Therefore, this study aimed to assess the motivational changes that took place during the pandemic in medical students and explored, how motivation of medical students is influenced. METHODS: Using a mixed method inter-cohort study design, 4th year medical students´ motivation, assessed pre- and post-pandemic were compared. In subsequent qualitative analyses underlying variables that may have contributed to both- medical students´ motivation and pandemic related changes were identified. These variables were then systematically explored- both individually and in combination. In a final step, the results were embedded within the Self-Determination Theory. RESULTS: Students who were affected by the university lockdown reported significantly higher levels of less self-determined motivation and amotivation. The qualitative analysis identified determinants that influence medical students´ motivation. The common core of these determinants is lacking social interaction and support, with a great emphasis on the interaction with the lecturer and patients. CONCLUSION: This study emphasizes the crucial role of medical educators, patient contact, social interactions and personal support on students´ motivation. Students need to be strengthened in their beliefs about their abilities, the value of their task at hand and receive encouragement in their efforts. All this will result in an increased identification with the task and less detrimental outcomes.

Infectious complications of radiologically placed upper arm ports: A single center analysis.

OBJECTIVES: Infections are common complications in venous access ports. The presented analysis aimed to investigate the incidence, microbiological spectrum, and acquired resistances of pathogens in upper arm port associated infections to provide a decision aid in the choice of therapy. MATERIALS AND METHODS: In total, 2667 implantations and 608 explantations were performed at a high-volume tertiary medical center between 2015 and 2019. In cases with infectious complications (n = 131, 4.9%), procedural conditions and results of microbiological testing were reviewed retrospectively. RESULTS: Of 131 port associated infections (median dwell time 103 days, interquartile range 41-260), 49 (37.4%) were port pocket infections (PPI) and 82 (62.6%) were catheter infections (CI). Infectious complications occurred more often after implantation in inpatients compared to outpatients (P < 0.01). PPI were mainly caused by Staphylococcus aureus (S. aureus, 48.3%) and coagulase-negative staphylococci (CoNS, 31.0%). Other gram-positive and gram-negative species were encountered in 13.8% and 6.9%, respectively. CI were caused less frequently by S. aureus (8.6%) than CoNS (39.7%). Other gram-positive and gram-negative strains were isolated in 8.6% and 31.0%, respectively. Candida species were seen in 12.1% of CI. An acquired antibiotic resistance was detected in 36.0% of all significant isolates, occurring especially in CoNS (68.3%) and gram-negative species (24.0%). CONCLUSIONS: Staphylococci comprised the largest group of pathogens in upper arm port associated infections. However, gram-negative strains and Candida species should also be considered as a cause of infection in CI. Due to the frequent detection of potential biofilm-forming pathogens, port explantation is an important therapeutic measure, especially in severely ill patients. Acquired resistances must be anticipated when choosing an empiric antibiotic treatment.
