Neurocognitive and psycho-emotional profile of children with disabilities.

OBJECTIVE: Neurocognitive deficits in attention, short-term memory, and sequential information processing are present in children with a variety of disabilities, whereas language and visuospatial abilities vary. METHOD: We compared the performance of 59 children (mean age, 15 years) with learning disabilities (n = 18), Down syndrome (n = 21), and intellectual disabilities (n = 20). A series of neuropsychological tests were used to evaluate the neurocognitive processes of memory, attention, visuospatial perception, and executive function. To better understand what emotions they experience, we assessed emotions like anxiety, depression, and positive and negative mood. RESULTS: The performance of children with Down syndrome was statistically significantly different from that of other groups, indicating lower performance (p = 0.001). In comparison to other groups, children with Down syndrome performed significantly worse across all cognitive domains. Additionally, there were no statistically significant differences between groups and low emotional functioning scores across the board for all children. People with DS frequently have distinctive neurocognitive and neurobehavioral profiles that appear during particular developmental phases and have many distinct strengths and weaknesses that should be respected as they mature over the course of their lives. The current findings have substantial consequences for interventions that are focused on achieving the best results.

Acalculous Cholecystitis in COVID-19 Patients: A Narrative Review.

Acute acalculous cholecystitis (AAC) represents cholecystitis without gallstones, occurring in approximately 5-10% of all cases of acute cholecystitis in adults. Several risk factors have been recognized, while infectious diseases can be a cause of cholecystitis in otherwise healthy people. Coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and has spread worldwide, leading to an unprecedented pandemic. The virus enters cells through the binding of the spike protein to angiotensin-converting enzyme 2 (ACE2) receptors expressed in many human tissues, including the epithelial cells of the gastrointestinal (GI) tract, and this explains the symptoms emanating from the digestive system. Acute cholecystitis has been reported in patients with COVID-19. The purpose of this review is to provide a detailed analysis of the current literature on the pathogenesis, diagnosis, management, and outcomes of AAC in patients with COVID-19.

What Do Cancer Surgery and orthopedic Surgery Elderly Patients Have in Common? A Long-term Postoperative Cognitive Dysfunction in Orthopedic and Cancer Patients Original Research.

Objectives-background: Postoperative cognitive dysfunction (POCD) involves decline in several cognitive domains after surgery and is particularly common after cardiac surgery, while also common among other types of surgery. Given the potential effects of such cognitive dysfunction on the quality of life, it is important to study it in multiple populations in order to limit its occurrence. Study design: We present the long-term neuropsychological outcome of 200 patients, 100 of whom had orthopedic surgery and 100 oncological surgery. Methods: We administered a series of neuropsychological tests assessing attention, complex scanning, verbal working memory, executive functioning, short-term and long-term memory, and visuospatial perception before surgery, prior to discharge, at 3-month follow-up and 6 years after surgery. We compared the performance of these patients to normative datasets. Results: Despite equivalent levels of pre-surgery performance between patients, oncology patients exceeded their preoperative neurocognitive levels, suggesting less postoperative cognitive dysfunction in orthopedic patients overall, in all neuropsychological domains at a 6-year follow-up, except short-term retention. In contrast, orthopedic patients showed no improvement, and, instead, showed some cognitive decline, which remained consistent over time. Conclusions: Our findings highlight the critical role of the type of surgery utilized in the development of POCD and have implications for clinical management and patients' quality of life in the very long term. Health policy professionals should be aware that patients' low POCD may persist in the long term, and this is useful from a clinician's point of view.

Protecting the Brain While Healing Hearts: The Protective Role of Cognitive Reserve in Cardiac Surgery.

OBJECTIVE: One of the most significant complications following coronary artery bypass grafting (CABG) is postoperative cognitive decline (POCD). CABG patients frequently experience considerable postoperative cognitive dysfunction (POCD), including decline in attention, orientation, memory, judgment, and social functioning. DESIGN: These negative effects may potentially be resolved by a protective factor, cognitive reserve (CR) that has been considered to function as a buffer against the consequences of neuropathology. SETTING: We explored the frequency of POCD and CR in coronary artery disease patients undergoing CABG. We hypothesized that high levels of CR would protect against POCD after cardiac surgery. PARTICIPANTS: We assessed 101 patients before surgery, and 4 months after cardiopulmonary bypass surgery with the use of extracorporeal circulation. MEASUREMENTS: Measures of cognitive functions, CR, anxiety, and depression were included in the assessment. RESULTS: Each patient was placed in the high (n = 50) or low CR (n = 51) group, based on median split. Chi-square tests effect showed that patients with low CR were more likely to a great extend to demonstrate postsurgical cognitive decline in attention, memory, visuospatial perception and executive functions than patients with high CR upon postsurgery neuropsychological assessment. CONCLUSIONS: Our results suggest that CR can forecast neuropsychological outcomes of cardiac surgery, recognizing the patients with low CR and help them to participate to interventions programs that could slow cognitive aging or reduce the risk of dementia and enhance their overall postsurgical functional outcome.

Neuropsychological Consequences of Massive Trauma: Implications and Clinical Interventions.

Traumatic events, especially massive trauma resulting from catastrophic incidents, wars, or severe abuse can elicit significant neuropsychological alterations, with profound implications for cognitive, emotional, and behavioral functioning. This mini-review delineates the primary neural changes post-trauma and underscores the importance of timely neuropsychological and clinical interventions. Specific brain regions, including the amygdala and prefrontal cortex, undergo physiological changes that can lead to memory impairments, attention deficits, and emotional disturbances. PTSD, a commonly diagnosed condition post-trauma, exemplifies the intricate relationship between trauma and memory processing. Furthermore, the concept of neuroplasticity, the brain's inherent ability to adapt and rewire, offers hope for recovery. Current clinical interventions, such as cognitive behavioral therapy, mindfulness practices, and biofeedback, leverage this neuroplastic potential to foster healing. The review underscores the vital importance of early intervention to mitigate long-term neuropsychological impacts, emphasizing the role of timely and targeted clinical interventions. The synthesis of this knowledge is crucial for clinicians, allowing for informed therapeutic approaches that holistically address both the physiological and psychological dimensions of trauma.

Neuropsychological functioning among patients with different types of cancer : Postchemotherapy cognitive impairment and implications for rehabilitation.

BACKGROUND: Chemotherapeutic drugs often contribute to the cognitive impairment observed in some individuals following chemotherapy treatment. Postchemotherapy cognitive impairment (PCCI) is referred to as a decline in a variety of neuropsychological measures after chemotherapy and has an acute onset. METHODS: The goals of the present study are to compare the manifestation of longitudinal PCCI among 182 patients with four different types of cancer (breast, colorectal, prostate and thyroid cancer) before chemotherapy (T1), immediately after chemotherapy (T2) and 6 months later (T3). RESULTS: Although no statistically significant differences were observed between the study groups in any of the cognitive domains before chemotherapy, patients with breast cancer showed significantly lower performance on all cognitive domains compared to other patients at the postchemotherapy timepoints. CONCLUSIONS: Although cognitive difficulties are reported during and after chemotherapy for cancer, it seems that there are differences between different types of cancer. We conclude that it is particularly important to assess and manage these cognitive disorders. Management includes rehabilitation programs that can improve cognitive functions and contribute to changes in brain functions to facilitate this improvement.

Language impairment among patients with different types of cancer. Comparison with healthy adults.

PURPOSE: Language dysfunction is a crucial deficit in terms of cognitive functioning, quality of life and activities of daily living. Several studies have identified cognitive impairment in patients with cancer across several cognitive domains, including language. METHODS: We investigated language functions among 182 patients with different types of cancer (not brain cancer) and compared them with the performance of Greek healthy adults with the same age and educational levels as the patients. The assessment included verbal fluency test, both semantic (animals) and phonological (X), and Boston Naming Test (BNT-60) among other neuropsychological measures. RESULTS: Breast cancer patients performed worse compared to patients with prostate, colorectal and thyroid cancer in language tasks. In addition, breast cancer patients had a decreased performance compared with healthy adults, while patients with other types performed to the mean in two out of three language tasks. CONCLUSIONS: Semantic and phonological fluency requirements of cognitive processes in the brain are discussed. IMPLICATIONS FOR CANCER SURVIVORS: Language dysfunction is a crucial deficit in terms of cognitive functioning, quality of life and activities of daily living, especially in brain cancer patients, but it can be crucial for patients with other types of cancer as stated in the present study.

Perioperative Use of Erythromycin Reduces Cognitive Decline After Coronary Artery Bypass Grafting Surgery: A Pilot Study.

OBJECTIVES: Adverse neurologic outcome can be a debilitating complication after cardiac surgery. The aim of this study was to investigate the potential neuroprotective action of erythromycin, a well known antibiotic agent, regarding postoperative cognitive decline in patients undergoing cardiac surgery. METHODS: Forty patients scheduled for elective coronary artery bypass grafting surgery were prospectively randomly assigned in 2 groups: the erythromycin group (n = 19) who received erythromycin at a dose of 25 mg/kg before and after surgery and the control group (n = 21) who did not receive it. All patients were monitored with near-infrared spectroscopy during the operation. Interleukin (IL) 1 and IL-6 as inflammatory markers and tau protein as a marker of brain injury were measured before and after surgery. Neurocognitive assessment was performed before surgery, on the day of discharge, and at 3 months postoperatively. RESULTS: Both groups were comparable in terms of demographic and clinical data. Patients who took erythromycin presented with significantly better cognitive performance before discharge and 3 months after surgery. No significant differences between the 2 groups referring to IL-1 and IL-6 values were detected. Tau serum values were lower in the erythromycin group after surgery. CONCLUSIONS: Erythromycin administration attenuates cerebral damage and postoperative cognitive decline after coronary artery bypass grafting surgery. TRIAL REGISTRATION: The study was retrospectively registered at ClinicalTrials.gov (NCT01274754). Study start day: November 2008.

Quality of Life in Chronic Disease Patients.

During the past decades there was an increasing predominance of chronic disorders, with a large number of people living with chronic diseases that can adversely affect their quality of life. The aim of the present paper is to study quality of life and especially Health-related quality of life (HRQoL) in chronic diseases. HRQOL is a multidimensional construct that consists of at least three broad domains - physical, psychological, and social functioning - that are affected by one's disease and/or treatment. HRQoL is usually measured in chronic conditions and is frequently impaired to a great extent. In addition, factors that are associated with good and poor HRQoL, as well as HRQoL assessment will be discussed. The estimation of the relative impact of chronic diseases on HRQoL is necessary in order to better plan and distribute health care resources aiming at a better HRQoL. [«All the people perceive the concept of living good or being well, that is the same as being happy¼. (Aristotle. 384-322 BC. Ethica Nichomachea)].

Working memory and verbal fluency in simultaneous interpreters.

We investigated working memory and verbal fluency in simultaneous interpreters, expecting to find enhanced working memory and semantic processing in interpreters relative to others fluent in a second language. The interpreters (n = 15) outperformed the control group (n = 35) on semantic fluency and most measures of working memory; their advantage over teachers of a foreign language (n = 15) approached, but did not reach, statistical significance. Our findings suggest that, while proficiency in a foreign language may enhance fluency and working memory skills, simultaneous interpreters have semantic processing and working memory capacities greater than those expected from mere proficiency in a foreign language.

Neurocognitive outcome after coronary artery bypass surgery using minimal versus conventional extracorporeal circulation: a randomised controlled pilot study.

OBJECTIVE: Neurocognitive impairment can be a debilitating complication after cardiac surgery. The aim of this study was to assess the effect of minimal extracorporeal circulation (MECC) versus conventional extracorporeal circulation (CECC) on neurocognitive function after elective coronary artery bypass grafting (CABG) and whether this can be attributed to improved cerebral perfusion intraoperatively. METHODS AND RESULTS: 64 patients scheduled for elective CABG surgery were prospectively randomly assigned to surgical revascularisation with MECC versus CECC. All patients were continuously monitored for changes in cerebral oxygenation with near-infrared spectroscopy during the procedure. Neurocognitive assessment was performed before surgery, on the day of discharge and at 3 months postoperatively using a battery of standardised neurocognitive tests. Both groups were comparable in terms of demographic and clinical data. MECC was associated with improved cerebral perfusion during cardiopulmonary bypass (CPB). Eleven patients operated on with MECC and 17 with CECC experienced at least one episode of cerebral desaturation (38% vs 55%, p=0.04) with similar duration (10 vs 12.3 min, p=0.1). At discharge patients operated on with MECC showed a significantly improved performance on complex scanning, visual tracking, focused attention and long-term memory. At 3 months significantly improved performance was also evident on visuospatial perception, executive function, verbal working memory and short-term memory. Patients operated on with MECC experienced a significantly lower risk of early cognitive decline both at discharge (41% vs 65%, p=0.03) and at 3-month evaluation (21% vs 61%, p<0.01). CONCLUSIONS: Use of MECC attenuates early postoperative neurocognitive impairment after coronary surgery compared with conventional CPB. This finding may have important implications on the surgical management strategy for coronary artery disease. CLINICAL TRIAL REGISTRATION NUMBER: The study is registered at ClinicalTrials.gov, number NCT01213511.

Non-pulsatile circulation with axial-flow left ventricular assist device preserves neurocognitive function.

Concerns about the potential impact of the non-pulsatile circulation pattern generated by the new generation axial-flow left ventricular assist devices on neurocognitive function led us to evaluate a patient in whom a Jarvik 2000 pump was implanted. We assessed the patient's baseline neurocognitive function preoperatively as well as at 1-month and 6-month follow-up, using a comprehensive battery of neuropsychological tests. A slight improvement in circumscribed neurocognitive domains was noted, with no evidence of further decline at the end of a 6-month follow-up period.
