Anti-LGI1 Autoimmune Encephalitis in a Patient with Rheumatoid Arthritis and MGUS.

Background: Anti-leucine-rich glioma inactivated 1 limbic encephalitis (anti-LGI1 LE) is one of the most frequent autoimmune encephalitis, commonly coexisting with other autoimmune diseases. Rheumatoid arthritis (RA) and monoclonal gammopathy of unknown significance (MGUS) are commonly associated with autoimmune phenomena. However, neither RA nor MGUS have been described in the literature to date as coexisting with anti-LGI1 LE. Case description: We present the case of anti-LGI1 LE in a male patient with rheumatoid arthritis, who was also found to have an MGUS. The patient was initially treated with corticosteroids and IV immunoglobulin. After a mild relapse, his treatment was complemented with rituximab, resulting in complete regression of the disease symptoms. Conclusions: Our report provides evidence for the coexistence of anti-LGI1 LE with RA and/or MGUS, thus extending the differential diagnosis of patients suffering with these disease entities that present with neuropsychiatric symptoms suggestive of encephalitis. Moreover, this case raises challenges on the management of the coexistence of these diseases, given the lack of therapeutic guidelines and their potential interaction on a pathophysiological and a clinical level. LEARNING POINTS: In a patient with known autoimmune or malignant background who presents with neuropsychiatric symptoms, after excluding infectious encephalitis or central nervous system involvement in the primary disease condition, autoimmune limbic encephalitis (LE) should also be considered.In a patient diagnosed with anti-LGI1 LE there should be an extensive check for coexisting occult pre-malignant conditions, even for months after disease presentation.Clinical management and treatment options of anti-LGI1 LE when coexisting with other autoimmune or pre-malignant conditions can be challenging; thus, more research is needed towards that direction.

Dietary Inflammatory Index score and prodromal Parkinson's disease incidence: The HELIAD study.

The aim of the present study was to investigate the association of the inflammatory potential of diet with prodromal Parkinson's disease (pPD) probability and incidence among community-dwelling older individuals without clinical features of parkinsonism at baseline. The sample consisted of 1,030 participants 65 years old or older, drawn from a population-based cohort study of older adults in Greece (Hellenic Longitudinal Investigation of Aging and Diet - HELIAD). We calculated pPD probability, according to International Parkinson and Movement Disorder Society research criteria. Dietary Inflammatory Index (DII) was used to measure the dietary inflammatory potential, with higher index score reflecting a more pro-inflammatory diet. Associations of baseline DII with pPD probability cross-sectionally, and with possible/probable pPD incidence (pPD probability ≥30%) during the follow-up period, were examined via general linear models and generalized estimating equations, respectively. Cross-sectionally, one unit increase of DII score [DII (min, max) = -5.83, 6.01] was associated with 4.9% increased pPD probability [ß=0.049, 95%CI (0.025-0.090), p<0.001]. Prospectively, 62 participants developed pPD during 3.1±0.9 (mean±SD) years of follow-up. One unit increase in DII was associated with 20.3% increased risk for developing pPD [RR=1.203, 95%CI (1.070-1.351), p=0.002]. Participants in the highest tertile of DII score were 2.6 times more likely to develop pPD [ß=2.594, 95%CI (1.332-5.050), p=0.005], compared to those in the lowest tertile. More pro-inflammatory diet was related with higher pPD probability and pPD incidence (pPD probability ≥30%) in a community-dwelling older adult population. Further studies are needed to confirm these findings.

An educational intervention to optimize use of proton pump inhibitors in a Greek university hospital.

BACKGROUND: Misuse of proton pump inhibitors (PPIs) is an alarming issue for patients and healthcare systems. METHODS: We conducted a 3-phase interventional, prospective study in a Greek university hospital. During Phase I, we collected data from patients' records to evaluate the appropriate use of PPIs. During Phase II, educational seminars about the proper use of PPIs were offered to the medical staff. In Phase III we collected data from the records of patients admitted to the hospital department with the highest rate of inappropriate PPI administration during Phase I, to evaluate the efficacy of the intervention. Inappropriate use was defined as either PPI administration without indication, or lack of use despite adequate indication. Appropriateness of PPI use was measured at admission, during hospitalization and at discharge. RESULTS: The rate of inappropriate PPI use was higher (51.7% and 48.6%) during hospitalization than at admission (34.9% and 21.9%), but at discharge was similar to pre-hospitalization levels (26.9% and 23.6%), in Phases I and III, respectively. At discharge during Phase I, the inappropriate use of PPIs was significantly higher (odds ratio 3.79, 95% confidence interval 1.98-7.19) for internal medicine patients than for surgical patients. The educational intervention failed to reduce the inappropriate use of PPIs during hospitalization (51.7% vs. 48.6%, P=0.478) or at discharge (26.9% vs. 23.6%, P=0.391) in the internal medicine patients. CONCLUSIONS: The rate of inappropriate PPI use is almost double during hospitalization compared to the rates at admission and at discharge. Implementation of an educational intervention failed to reduce the inappropriate use of PPIs in internal medicine patients.

Hand hygiene education of Greek medical and nursing students: A cross-sectional study.

AIM: To investigate medical and nursing students' education on hand hygiene, their attitude on hand hygiene education and how this education influences their hand hygiene knowledge and practices. BACKGROUND: Hospital-acquired infections are associated with prolonged hospitalisation and mortality. The most effective measure for their control is healthcare workers' hand hygiene compliance. Since medical and nursing students constitute the future healthcare workers, our study focuses on them. DESIGN: Cross-sectional study METHODS: This study was conducted during the academic year 2016-2017, using a modified World Health Organisation questionnaire. Our sample consisted of 132 medical and 111 nursing students from National and Kapodistrian University of Athens, Greece. In data analysis, the Mann-Whitney and Fisher's exact tests were applied to compare differences in continuous variables and proportions in categorical variables, respectively. Knowledge and practices overall scores were calculated per student group. Multiple linear regression analyses were performed to assess the influence of potential confounders on these scores. RESULTS: We found that 73.1% of medical and 98.2% of nursing students had received relevant education, which was reported as "only theoretical" by 77.4% of the former and as "hands-on and theoretical" by 88.1% of the latter group. Besides the risk of infection, knowledge acquired in lectures and trainer's behaviour were also considered very influential factors shaping hand hygiene attitude in both groups. Overall, medical students reported better hand hygiene practices than nursing ones (69.9% and 59.7%, respectively; p < 0.001). The opposite finding was observed regarding their overall knowledge on hand hygiene (57.2% of medical versus 60.4% of nursing students, p = 0.04). The majority of students (86.6% of all participants; p < 0.001) supported the inclusion of compulsory hand hygiene education in their curriculum. Compulsory education and seminars were assessed as the most effective measures to increase hand hygiene compliance (71.4% of all students). CONCLUSION: In our study, medical students scored better in practices questions than nursing students; this did not apply for the knowledge score. The majority of students supported the inclusion of compulsory education on hand hygiene principles in their Departments' curricula, highlighting compulsory education and seminars as the most effective measures to increase compliance with hand hygiene.
