Objective. The goal of this study was to explore the relationship between acute psychological reactions and cognition as well as postconcussive symptoms in patients with MTBI. Research Methods. Sociodemographic and medical history data were gathered for 59 patients diagnosed with MTBI. Validated and standardized tools were used to assess anxiety, depression, and cognitive function two weeks after trauma. Postconcussive symptoms were assessed with the Rivermead postconcussive questionnaire. Results. Despite the absence of significant neuropsychological deficits, a very high level of anxiety and depression was observed in our cohort. Level of anxiety and depression were positively related to cognitive performances and to postconcussive symptoms. Moreover, patients with preexisting alcohol and psychological problems were more likely to present with acute depression after MTBI. Conclusions. Early psychological rehabilitation should be provided to decrease the intensity and frequency of postconcussive symptoms and diminish the risk of these problems becoming chronic.

Anxiety Depression

Medicine is a stressful job. It is shown in several studies that decreased clinical function, disturbance in decision making, and the doctor-patient relationship, anxiety, depression, alcohol and substance abuse, and suicide are associated with stress. So, it is important to investigate the prevalence of depression, anxiety, and stress among medical staff. This is a cross-sectional study on the Tehran University of Medical Sciences residents, and 152 residents were surveyed by the DASS-21 questionnaire, which measures the depression, anxiety, and stress level. One hundred fifty-two residents (24.5% male, 75.5% female) with a mean age of 29.6 (SD=2.96) were surveyed. According to this study results, 23% of residents had severe to extremely severe depression, 24.9% had severe to extremely severe anxiety, and 33.8% had severe to extremely severe stress. Prevalence of depression, anxiety, and stress among Tehran University of Medical Sciences residents are higher than some other countries and universities, and it could be due to more working pressure in our educational hospitals. However, similar studies in different countries have not similar results, especially about the associated factors; so, more studies should be done, especially with the interventional and socioeconomic considerations, to address these issues.

Background. Heat therapy is widely used for therapeutic purposes in health SPA resorts or hospitals. However, its benefits and consequences are not strongly evidenced and it is partially-related with a lack of experimental information. No one has explored how continuous head and neck warming applied in thermoneutral environment can affect body temperatures, subjective sensations and cognition and the purpose of this study was to investigate it. Methods. Seven subjects (21 ± 1 years) participated in two experimental trials: CON – control trial; and CONW – head and neck warming trial. These trials were designed to introduce the effects of continuous head and neck warming (surface warming by 44 ± 1°C) on thermal sensations, body temperatures and cognitive function in thermoneutral environment (24°C and 60% relative humidity). In each trial body temperatures (rectal, Tre; mean skin, Tsk), heart rate (HR) response, ratios of subjective sensations (SS) and cognitive function were assessed. Results. Head and neck warming (CONW trial) maintained significantly higher Tre and Tsk values (by 0.2 ± 0.1°C and 1 ± 0.3 °C, respectively), compared to the control (CON) trial. Head and neck warming caused significant increment in heart rate (8 ± 2 b/min) and improved thermal sensation (p < .05), but had no effect on shivering/ sweating sensation and thermal comfort. Moreover, head and neck warming (CONW trial) does not induce any significant impact on accuracy (p > .05) and response times (p >.05) in mathematical and spatial processing tasks. Conclusions. Continuous head and neck warming applied in thermoneutral conditions maintains higher internal (Tre) and peripheral (Tsk) body temperatures and improves thermal sensation, but does not alter cognitive function.

Purpose: To examine the effects of precooling via crushed ice ingestion on cognitive function during exercise in the heat. Methods: Eleven active men ingested either 7 g·kg−1 of crushed ice (ICE) or thermoneutral water (CON) 30 minutes before running 90 minutes on a treadmill at a velocity equivalent to 65% VO2peak in hot and humid conditions (35.0°C [0.5°C], 53.1% [3.9%] relative humidity). Participants completed 3 cognitive tasks to investigate decision making (8-choice reaction time [CRT]), working memory (serial seven [S7]), and executive control (color multisource interference task [cMSIT]) on arrival, after precooling, and after running. Results: Precooling significantly decreased preexercise core (Tcore) and forehead skin temperature in ICE compared with CON, respectively (Tcore 0.8°C [0.4°C], –0.2°C [0.1°C]; Thead –0.5°C [0.4°C], 0.2°C [0.8°C]; P ≤ .05). Postrun, ICE significantly reduced errors compared with CON for CRT (P ≤ .05; d = 0.90; 90% confidence interval, 0.13–1.60) and S7 (P ≤ .05; d = 1.05; 90% confidence interval, 0.26–1.75). Thermal sensation was lower after precooling with ICE (P ≤ .05), but no significant differences were recorded between conditions for cMSIT errors, skin temperature, heart rate, or ratings of perceived exertion or perceived thirst (P > .05). Conclusions: Precooling via ICE maintained cognitive accuracy in decision making and working memory during exercise in the heat. Thus, ICE may have the potential to improve sporting performance by resisting deleterious effects of exercise in a hot and humid environment on cognitive function.

Purpose Cognitive dysfunction is reported in people with cancer. Therefore, we evaluated longitudinal changes in cognitive function and underlying mechanisms in people with colorectal cancer (CRC) and healthy controls (HCs). Patients and Methods Participants completed cognitive assessments and questionnaires reporting cognitive symptoms, fatigue, quality of life, and anxiety/depression at baseline (before chemotherapy, if given) and 6, 12, and 24 months. Blood tests included cytokines, clotting factors, apolipoprotein E genotype, and sex hormones. Primary end point was overall cognitive function measured by the Global Deficit Score at 12 months. Results We recruited 289 patients with localized CRC (173 received chemotherapy; median age, 59 years; 63% male), 73 patients with limited metastatic/recurrent CRC, and 72 HCs. Cognitive impairment was more frequent in patients with localized CRC than HCs at baseline (43% v 15%, respectively; P < .001) and 12 months (46% v 13%, respectively; P < .001), with no significant effect of chemotherapy. Attention/working memory, verbal learning/memory, and complex processing speed were most affected. Cognitive impairment was similar in patients with localized and metastatic CRC. Cytokine levels were elevated in patients with CRC compared with HCs. There was no association between overall cognitive function and fatigue, quality of life, anxiety/depression, or any blood test. Cognitive symptoms at 12 months were reported in 25% of patients with localized CRC versus 17% of HCs (P = .19). More participants who received chemotherapy had cognitive symptoms at 6 months (32%) versus those who did not (16%; P = .007), with no significant difference at 12 months (29% v 21%, respectively; P = .19). Objective cognitive function was only weakly associated with cognitive symptoms. Conclusion Patients with CRC had substantially more cognitive impairment at every assessment than HCs, with no significant added effect of chemotherapy. Mechanisms of cognitive impairment remain unknown.

Background: Personal protective equipment (PPE) is an essential component of safely treating suspected or confirmed SARS-CoV-2 patients. PPE acts as a barrier to heat loss, therefore increasing the risk of thermal strain which may impact on cognitive function. Healthcare workers (HCWs) need to be able to prioritize and execute complex tasks effectively to ensure patient safety. This study evaluated pre-cooling and per-cooling methods on thermal strain, thermal comfort and cognitive function during simulated emergency management of an acutely unwell patient.Methods: This randomized controlled crossover trial was run at the Clinical Services Department of the Medical Research Unit The Gambia. Each participant attended two sessions (Cool and Control) in standard PPE. Cool involved pre-cooling with an ice slurry ingestion and per-cooling by wearing an ice-vest external to PPE.Results: Twelve participants completed both sessions. There was a significant increase in tympanic temperature in Control sessions at both 1 and 2 h in PPE (p = 0.01). No significant increase was seen during Cool. Effect estimate of Cool was −0.2°C (95% CI −0.43; 0.01, p = 0.06) post 1 h and −0.28°C (95% CI −0.57; 0.02, p = 0.06) post 2 h on tympanic temperature. Cool improved thermal comfort (p &lt; 0.001), thermal sensation (p &lt; 0.001), and thirst (p = 0.04). No difference on cognitive function was demonstrated using multilevel modeling.Discussion: Thermal strain in HCWs wearing PPE can be safely reduced using pre- and per-cooling methods external to PPE.

9557 Background: A subset of women with breast cancer have cognitive impairment &/or fatigue before and after chemotherapy (CTh). We evaluated these symptoms and potential mechanisms prior to CTh in patients with CRC. Methods: Chemo-naïve patients with stage I-III CRC (Group 1) and pts with limited stage IV CRC prior to 1st line metastatic CTh (Group 2) were evaluated. Neuropsychological (NP) performance was assessed by classical and computerized (CANTAB) test batteries, with cognitive impairment defined using a global deficit score approach, and concurrent questionnaires for fatigue & quality of life (FACT-F), anxiety/depression (GHQ), and perceived cognitive function (FACT-COG). Group 1 had blood tests to evaluate 10 cytokines, clotting factors, sex hormones, CEA and apoE genotype. Primary endpoints were cognitive function (classical tests) and fatigue in group 1. Associations between test results, demographic and disease-related factors were sought. Results: We assessed 326 patients: Group 1, 253 (post-surgery [median 56 days] 174; pre-surgery 79); Group 2, 73. Median age was 59 (23–75); 61% were male. In group 1, 36% had cognitive impairment on classical tests & 29% on CANTAB; 32% and 30% in group 2. No differences were seen by disease stage or surgery status. Men had more cognitive impairment than women on classical tests (p=.001). Self-reported cognitive symptoms was 10%; higher in women (p=.08). Fatigue, QOL, anxiety/depression & self-reported cognitive symptoms were strongly associated with each other (r=.45-.76, p<.0001), but not with NP test performance. Fatigue was 52% in Group 1 vs 66% in Group 2 (p=.03); and greater in women (p=.002). All cytokines were elevated compared to healthy volunteers (p<.001). Cognitive function and fatigue prior to CTh were not associated with cytokines, sex hormones, clotting factors, CEA or apoE genotype. Symptoms of anxiety/depression were reported by 13% of group 1 pts vs 25% in group 2 (p=.02). Conclusions: Cognitive impairment was present in 36% of CRC patients prior to adjuvant CTh, with 10% self-reporting impairment and 52% reporting fatigue. Cytokine levels were elevated but were not associated with cognitive function or fatigue. The etiology of cognitive impairment prior to cancer treatment remains unknown. No significant financial relationships to disclose.
