Brain 18FDG-PET pattern in patients with alcohol-related cognitive impairment
AbstractPurposeBrain positron emission tomography using 18F-fluorodeoxyglucose (18FDG-PET) provides a metabolic assessment of brain function that is useful for differential diagnosis among several neurodegenerative diseases manifested by cognitive impairment (CI). The purpose of the study is to describe the pattern of 18FDG-PET abnormalities in patients with CI related to alcohol use disorder.MethodsPatients admitted to the addiction medicine department of a university hospital in Paris between January 2017 and October 2018 with a confirmed diagnosis of alcohol-related cognitive impairment (ARCI) or Wernicke encephalopathy (WE) were included. Brain 18FDG-PET uptake was measured after at least 1 month of monitored abstinence from alcohol. Standardized uptake values were obtained for 13 regions of interest (ROI) and normalized to the pons. Individual patients’ ROIZ-scores were calculated from healthy sex- and age-matched controls provided by Cortex ID software.ResultsTwenty-five patients were included in the analysis (20 males and 5 females; mean age 57.6 years (45–76 years old)). The group consisted of 19 ARCI and 6 WE cases. The mean hypometabolism was most severe in the prefrontal medial cortex (PFM) (− 2.80 (± 1.30)), the prefrontal lateral cortex (− 2.20 (± 1.35)), and the anterior cingulate cortex (− 2.24 (± 1.19)).

CONCLUSIONS: Immunohistochemistry seems to be a promising option not only in clinical recognition, but also in the selection and monitoring of treatment effects. However, these methods have not yet recommended for routine clinical use. PMID: 33032462 [PubMed - as supplied by publisher]
CONCLUSIONS: Considering the low number of university students disclosing sexual assaults to health professionals or support services, the results of this survey suggest more work is needed to facilitate greater disclosures to health professionals enabling victims to access the services they need regardless of alcohol use.

CONCLUSION: The nurse practitioner workforce offers stability and flexibility in working across multiple clinical settings in primary healthcare. They provide the potential solution to the general practitioner workforce shortage by improving access to primary healthcare and reducing health inequalities. As authorised prescribers able to enrol patients, receive capitation payments and claim general medical services, it is timely to facilitate the expansion of the nurse practitioner workforce in New Zealand.

CONCLUSIONS: Paramagnetic rims might be a characteristic MRI finding for MS, and therefore they have potential as an imaging marker for differentially diagnosing MS from NMOSD using 3-T MRI. PMID: 33029961 [PubMed]
CONCLUSION: When gastroenterologists encounter NAFLD/NASH patients, serum CK should be verified. If hyperCKemia, frontal baldness, a hatched face, history of cataract surgery, and grip myotonia are noted, the possibility of MD may be considered. PMID: 33033573 [PubMed]

CONCLUSION: The ultrasonography measure of right liver lobe diameter by itself can reliably identify patients with NAFLD with a good sensitivity and specificity, however, this can be improved by adding the LAP mathematical index in our population. PMID: 33031969 [PubMed - as supplied by publisher]
Abstract OBJECTIVE: The survey aimed to estimate, in the presence of alcohol use disorder, the frequency of systematic prescription of thiamine, the factors associated with it, and those related to the administration (oral, intravenous, intramuscular) when Wernicke's encephalopathy is suspected. METHODS: A self-questionnaire available on Internet was sent by e-mail to doctors and nurses taking care patients with alcohol use disorder. RESULTS: In all, 565 professionals responded. The systematic prescription frequency of thiamine was 84.8 %, addiction care centers and medical-psychological center...
Conclusion: Substitution of parenteral thiamine in individuals with suspected WE is a well-established treatment regimen. However, suggestions according to guidelines vary widely. Furthermore, hardly any evidence-based recommendations exist on a more general use of thiamine as a preventative intervention in individuals with AUD. Further research is of utmost importance to raise awareness for this potentially undervalued problem.Eur Addict Res 2019;25:103 –110
