ObjectiveTo evaluate the epidemiologic features of psychiatric comorbidities following mild traumatic brain injury (MTBI, or concussion) in a state-wide hospital system cohort over a 10-year period.BackgroundThe epidemiology of neuropsychiatric symptoms and diagnoses following concussion are poorly understood. Despite the rebirth of post-concussion syndrome (PCS) as persistent post-concussion symptoms (PPCS), entailing diverse and complex somatic, cognitive, and emotional components with significant potential overlap or confounding of psychiatric comorbidities, there is scarce characterization of the incidence of such comorbidities following concussion. The study of demographic factors as they relate to psychiatric diagnoses following concussion remains in infancy.Design/MethodsWe conducted an observational retrospective cohort study of all patients who received a diagnosis of concussion within Ochsner Health (OH) over a 10-year period. System-wide electronic medical records were evaluated using ICD-10 codes to collect data on patients with a diagnosis of MTBI or concussion, as compared to patients with no diagnosis of concussion over the same period. Data on subpopulations corresponding to psychiatric diagnostic outcomes following diagnosis of concussion were collected and evaluated to determine timeline-related incidences of outcomes, as well as on demographic and morbid features corresponding to each outcome. These included age, sex, race, ethnicity, household income, neurologic and psychiatric history, cause of concussion, and presence of loss of consciousness.ResultsWe report incidence, demographic, and morbid factor data on patients with a diagnosis of concussion, and as related to outcomes following diagnosis of concussion, including: (1) new diagnosis of PCS, (2) meeting PPCS Berlin Sport Concussion Consensus criteria, (3) new unclassified neuropsychiatric symptoms, (4) any new psychiatric diagnosis, (5) new psychiatric diagnosis excluding PCS, (6) new anxiety, dissociative, stress-related, or somatoform disorder diagnosis, (7) new reaction to severe stress or adjustment disorder diagnosis, and (8) new PTSD diagnosis.ConclusionsWe call for multidisciplinary awareness, screening, and longitudinal research of patients with concussion.

Adjustment Disorder (AD) is one of the most common psychiatric diagnoses employed. In fact, it is the most frequent diagnosis utilized for psychiatric disorders in the military and in children, and is often utilized in the consultation-liaison medical setting. However, it is acknowledged that the diagnosis is not reliable, it cannot be validated, and it has an important degree of subjective consideration in its use. Commonly used screening tools like the Hamilton and Beck Depression Scales do not give an assessment of AD. Furthermore, its use is accompanied with descriptors of depression, anxiety, mixed affects, etc., so that it crosses over several areas of psychiatric dysfunction. It does allow the placement of a patient within a psychiatric diagnosis when they do not reach criteria for a major psychiatric nomenclature. To date, biological studies have not been reported. It is not known if AD with depression is closer to the biological characteristics of depression, or AD with anxiety would have similar characteristics to that seen with major anxiety. It is also not known if AD has a biological signature that would make them an entity with common features, or if they may be more closely allied biologically with the descriptor that accompanies them. Nevertheless, AD is an important category in any psychiatric lexicon and warrants further study and biological understanding.

Preoperative Examination

Forty consecutive liver transplantation candidates underwent a standard psychiatric evaluation as part of a multidisciplinary preoperative examination. Psychiatric diagnoses were determined using DSM-III criteria and correlations between the psychiatric diagnoses and the results of bedside cognitive examinations, biochemical measures of hepatic function, and EEG's were made. Half of the patients could not be given a specific psychiatric diagnosis despite the fact of their being in terminal stages of a severe medical illness and being stressed by the uncertainty of whether they would be accepted for possible liver transplantation. Of the twenty patients given a psychiatric diagnosis, 60 percent were found to be delirious and 35 percent had an adjustment disorder. Delirium was associated with a serum albumin less than 3.0 g/dl, grades 1 through 3 EEG dysrhythmias, a Mini Mental State score less than 24 or impairment on Trailmaking Tests. In addition, discriminant analyses were performed to determine which batteries of tests best differentiated the delirious patients. A unique pattern of psychosocial stressors was noted in these patients where the severity of overall stress and of occupational dysfunction was high in most, yet family and social relationships were reported as less affected.

Abstract Background The syndrome of inappropriate sinus tachycardia (IST) is well recognized and affects ∼1% of the population. We believe IST in pregnancy is a relatively frequent yet under-recognized phenomenon that may represent a distinct arrhythmia. To date, there are only three case reports in the literature. Purpose To further understand the natural history of IST in pregnancy, and to explore maternal outcomes. Methods A retrospective, observational cohort analysis. Results 19 pregnant women presented to our institute with a definitive diagnosis of IST (as defined by task force criteria) between January 2016 and January 2017. Symptom onset was 4–36 weeks gestation (mean 20 weeks). Of those in their second or subsequent pregnancy (n=8), 50% described symptoms compatible with IST in previous pregnancies. 42% attended the emergency department on ≥1 occasion with symptoms of IST. 32% required hospital admission. 26% required pharmacological therapy (beta-blockers in all). There were no maternal deaths, instances of heart failure or acute coronary syndrome, no thromboembolic or haemorrhagic complications during pregnancy. Rates of Caesarean section were similar to the background rate of our unit; however, rates of induction were notably elevated (58% vs 25%), with 55% of these women being induced purely for symptoms of IST. Following delivery, symptoms resolved within one week for 17 of the women in the cohort, 1 had symptoms resolve after 4 month and 1 had persistent symptoms as she became pregnant again. Conclusion IST in pregnancy likely represents a distinct arrhythmia; the majority of individuals here had symptoms only during pregnancy, which resolved rapidly postpartum. Additionally, half of the women in a second or subsequent pregnancy had suffered IST symptoms during previous pregnancies, with no symptoms in between pregnancies. It is biologically plausible and may represent an exaggerated cardio-autonomic response to the physiological changes of pregnancy such as increased sympathetic tone and change in baroreceptor reflex sensitivity. Recognition of the condition is important given it is associated with significant morbidity, the distressing nature of symptoms leading to high rates of hospitalization and induction of labour.

B12 Deficiency

ObjectivesOur study investigated the use of vitamin B12 testing in a large cohort of patients on metformin and assesses appropriateness and benefits of screening recommendations for vitamin B12 deficiency.DesignThis retrospective cohort study included insured adult patients who had more than 1 year of metformin use between 1 January 2010 and 1 October 2016 and who filled at least two consecutive prescriptions of metformin to establish compliance. The comparison group was not exposed to metformin. Primary outcome was incidence of B12 deficiency diagnosed in patients on metformin. Secondary outcome was occurrence of B12 testing in the patient population on metformin. Records dated through 31 December 2018 were analysed.SettingLarge hospital system consisting of inpatient and outpatient data base.ParticipantsA diverse, adult, insured population of patients who had more than 1 year of metformin use between 1 January 2010 and 1 October 2016 and who filled at least two consecutive prescriptions of metformin.ResultsOf 13 489 patients on metformin, 6051 (44.9%) were tested for vitamin B12 deficiency, of which 202 (3.3%) tested positive (vs 2.2% of comparisons). Average time to test was 990 days. Average time to test positive for deficiency was 1926 days. Factors associated with testing were linked to sex (female, 47.8%), older age (62.79% in patients over 80 years old), race (48.98% white) and causes of malabsorption (7.11%). Multivariable logistic regression showed older age as the only factor associated with vitamin B12 deficiency, whereas African-American ethnicity approached significance as a protective factor.ConclusionsBased on our study’s findings of vitamin B12 deficiency in patients on metformin who are greater than 65 years old and have been using it for over 5 years, we recommend that physicians consider screening in these populations.
