Nocturnal dexmedetomidine alleviates post–intensive care syndrome following cardiac surgery: a prospective randomized controlled clinical trial

Background Dexmedetomidine is a sedative agent that may have the potential to reduce the risk of post-intensive care syndrome (PICS). This study aimed to establish whether prophylactic nocturnal dexmedetomidine safely reduces postoperative PICS incidence and to develop an easy-to-use model for predicting the risk of PICS following cardiac surgery. Methods This was a single-center, double-blind, randomized, prospective, placebo-controlled trial. Patients undergoing cardiac surgery were randomly assigned (1:1) to dexmedetomidine or placebo (normal saline) groups between January 2019 and July 2020. Dexmedetomidine or a similar volume of saline was administered, with an infusion rate up to 1.2 μg/kg/h until the RASS remained between − 1 and 0. The primary study endpoint was PICS incidence at 6 months follow-up, as defined by cognitive, physical, or psychological impairments. Results We assessed 703 individuals for eligibility, of whom 508 were enrolled. Of these, there were 251 in the dexmedetomidine group and 257 in the placebo group that received the trial agent, forming a modified intention-to-treat population. PICS incidence at 6-month follow-up was significantly decreased in the dexmedetomidine group (54/251, 21.5%) relative to the placebo group (80/257, 31.1%) (odds ratio [OR] 0.793, 95% CI 0.665–0.945; p = 0.014). Psychological impairment was significantly reduced in the dexmedetomidine group relative to the placebo group (18.7% vs. 26.8%, OR 0.806, CI 0.672–0.967, p = 0.029). However, dexmedetomidine treatment was associated with a higher rate of hypotension. A nomogram revealed that age, education, a medical history of diabetes and smoking, dexmedetomidine treatment, postoperative atrial fibrillation, and sequential organ failure assessment scores at 8 h post-surgery were independent predictors of PICS. Conclusions Prophylactic nocturnal dexmedetomidine administration significantly reduced PICS incidence by a marked reduction in psychological impairment within a 6-month follow-up period.

Quality Of Life In Nepalese Patients With Alopecia: A Cross-Sectional Observational Study At A Tertiary Center (Preprint)

BACKGROUND Alopecia areata (AA) and Androgenetic alopecia (AGA) are fairly common hair disorders. Hair loss causes a significant impact in person’s life which may lead to loss of self-confidence and distorted body image. OBJECTIVE To find the level of impairment in the quality of life in patients with AA and AGA and compare findings between sexes and diagnoses. METHODS All consenting patients with hair loss presenting to the clinic from September 2020 to August 2021 were enrolled in this observational study. Clinical evaluation for AA and severity grading as percentage of scalp involved was recorded. Similarly, alopecia severity grading in AGA was done using Norwood and Hamilton grading in males and Ludwig grading in females. All participants were asked to complete the Nepali Dermatology Life Quality Index (DLQI) questionnaire. RESULTS Out of 142 patients, there were 79 (55.6%) males and 63 (44.4%) females. There were 48 (33.8%) patients of AA while ninety-four (66.2%) had AGA. The mean total DLQI score was 8.16 (±6.126). Mean DLQI score of females was 9.16±5.858 which was significantly higher than that of males 7.37±6.258 (P<0.05). DLQI of the AGA patients (9.45±6.094) was significantly higher than that of AA patients (5.65±5.417) (P<0.001). All sub-domains of the DLQI in females were impaired more than in males. Increasing duration of the disease increased the impairment in quality of life significantly. CONCLUSIONS The quality of life in females was more affected as compared to males in both kinds of hair loss. However, patients with AGA had a greater impairment than patients with AA in our population. Hair loss specific questionnaires in local language would better measure the psychological impairment.

Hospital workers mental health during the COVID-19 pandemic: methods of data collection and characteristics of study sample in a university hospital in Milan (Italy)

Background The COVID-19 pandemic is currently a severe challenge for healthcare workers, with a considerable impact on their mental health. In order to focus preventive and rehabilitation measures it’s fundamental to identify risk factors of such psychological impairment. We designed an observational longitudinal study to systematically examine the psychological wellbeing of all employees in a large University Hospital in Italy, using validated psychometric scales in the context of the occupational physician’s health surveillance, in collaboration with Psychiatric Unit. Methods The study started after ethical approval in August 2020. For each worker, the psychological wellbeing is screened in two steps. The first level questionnaire collects sociodemographic characteristics, personal and occupational COVID-19 exposure, worries and concerns about COVID-19, general psychological discomfort (GHQ-12), post-traumatic stress symptoms (IES-R) and anxiety (GAD-7). Workers who score above the cut-off in at least one scale are further investigated by the second level questionnaire composed by PHQ-9, DES-II and SCL-90. If second level shows psychological impairments, we offer individual specialist treatment (third level). We plan to follow-up all subjects to monitor symptoms and possible chronicization; we aim to investigate potential risk factors through univariate analysis and multivariate logistic regressions. Results Preliminary results refer to a sample of 550 workers who completed the multi-step evaluation from August to December 2020, before vaccination campaign started. The participation rate was 90%. At first level screening, 39% of the subjects expressed general psychological discomfort (GHQ-12), 22% post-traumatic stress symptoms (IES-R), and 21% symptoms of anxiety (GAD-7). Women, nurses, younger workers, subjects with COVID-19 working exposure and with an infected family member showed significantly higher psychological impairment compared to colleagues. After the second level screening, 12% and 7% of all workers showed, respectively, depressive and dissociative symptoms; scorings were significantly associated with gender and occupational role. We are currently extending sample size and evaluating subjects over a period of further 12 months. Conclusions The possibility to perform a systematic follow-up of psychological wellbeing of all hospital workers, directly or indirectly exposed to pandemic consequences, constitutes a unique condition to detect individual, occupational, and non-occupational risk factors for psychological impairment in situations of prolonged stress, as well as variables associated with symptoms chronicization.

Evolution, Biology, and Aggression

There are numerous complementary approaches to the biology of aggression, ranging from genetic to cognitive research. Arguably, the most successful of them have been guided by hypotheses derived from evolutionary theory. In contrast to the view that human aggression is symptomatic of psychological impairment, social disorganization, or both, evolution-minded hypotheses typically begin from the premise that aggression has been designed by natural selection to serve one or more adaptive functions, and that the mechanisms involved can be sensitive to cues of reproductive consequences in the social environment. Specifically, anatomical, physiological, and psychological adaptations for aggression are expected to evolve when they help individuals secure resources and matings for themselves and for their genealogical kin. From a theoretical perspective, contexts of predation, sexual competition, and sexual conflict are especially likely to foment aggression. A considerable body of research on aggression in nonhuman animals reinforces the adaptationist position, and central findings of this viewpoint—such as differential risk of violence according to sex and kinship—are closely mirrored in humans. Although many features of human aggression are likely the result of adaptations designed to yield these very features, others are more plausibly understood as byproducts of adaptations designed for different purposes. In either case, evolutionary approaches can help to identify the mechanisms underlying aggression and thereby provide ways to reduce its impact.

Telephone-based assessment of multiple sclerosis patients at Ain Shams University Hospital in the coronavirus disease 2019 pandemic

Background Assessment of multiple sclerosis (MS) patients during the era of the coronavirus disease 2019 (COVID-19) pandemic was confronted with the overwhelmed healthcare facilities in Egypt and fear of the patients to get infected while attending the follow-up visits. This study aimed to assess the value of telephone-based assessments in the follow-up of MS patients. It includes one hundred and five patients who participated in the study and completed 3 telephone-based assessments which are the Hauser Ambulation index, Multiple Sclerosis Neuropsychology Questionnaire (MSNQ), and Symptoms of Multiple Sclerosis Scale (SMSS). Results The Hauser Ambulation index was significantly correlated with the latest Expanded Disability Status Scale (EDSS) score done within 1 month from the telephone call (r=0.738, P<0.001). The analysis of MSNQ scores showed that one-third of the study population had evidence of cognitive and/or neuropsychological impairment. Post hoc analysis regarding the cognitive and psychological impairment component of SMSS revealed that the patients who answered “Never” had significantly lower MSNQ scores compared to those who answered “Sometimes” (P=0.016), “Often” (P=0.022), and “Always” (P=0.001). The comparison of the EDSS scores of the patients regarding the sensory-motor impairment component of SMSS showed a non-significant difference. Conclusion The Hauser Ambulation index may be a reliable telephone-based tool for the assessment of physical disability. The MSNQ and the cognitive and psychological impairment component of SMSS can be used for the assessment of cognitive and psychological impairment among patients with MS.

The association of proBNPage with manifestations of age-related cardiovascular, physical, and psychological impairment in community-dwelling older adults

NT-proB-type natriuretic peptide (NT-proBNP) serum concentration can be transformed by simple formulas into proBNPage, a surrogate of biological age strongly associated with chronological age, all-cause mortality, and disease count. This cross-sectional study aimed to assess whether proBNPage is also associated with other manifestations of the aging process in comparison with other variables. The study included 1117 noninstitutionalized older adults (73.1 ± 5.6 years, 537 men). Baseline measurements of serum NT-proBNP, erythrocyte sedimentation rate, hemoglobin, lymphocytes, and creatinine, which have previously been shown to be highly associated with both age and all-cause mortality, were performed. These variables were compared between subjects with and without manifestations of cardiovascular impairment (myocardial infarction (MI), stroke, peripheral artery disease (PAD), arterial revascularizations (AR)), physical impairment (long step test duration (LSTD), walking problems, falls, deficit in one or more activities of daily living), and psychological impairment (poor self-rating of health (PSRH), anxiety/depression, Mini Mental State Examination (MMSE) score < 24). ProBNPage (years) was independently associated (OR, 95% CI) with MI (1.08, 1.07–1.10), stroke (1.02, 1.00–1.05), PAD (1.04, 1.01–1.06), AR (1.06, 1.04–1.08), LSTD (1.03, 1.02–1.04), walking problems (1.02, 1.01–1.03), and PSRH (1.02, 1.01–1.02). For 5 of these 7 associations, the relationship was stronger than that of chronological age. In addition, proBNPage was univariately associated with MMSE score < 24, anxiety/depression, and falls. None of the other variables provided comparable performances. Thus, in addition to the known associations with mortality and disease count, proBNPage is also associated with cardiovascular manifestations as well as noncardiovascular manifestations of the aging process.

Maladaptive Daydreaming in an Adult Italian Population During the COVID-19 Lockdown

During the COVID-19 outbreak, individuals with or without mental disorders may resort to dysfunctional psychological strategies that could trigger or heighten their emotional distress. The current study aims to explore the links between maladaptive daydreaming (MD, i.e., a compulsive fantasy activity associated with distress and psychological impairment), psychological symptoms of depression, anxiety, and negative stress, and COVID-19-related variables, such as changes in face-to-face and online relationships, during the COVID-19 lockdown in Italy. A total of 6,277 Italian adults completed an online survey, including socio-demographic variables, COVID-19 related information, the 16-item Maladaptive Daydreaming Scale (MDS-16), and Depression, Anxiety, and Stress Scales-21 Items (DASS-21). Based on an empirically derived cut-off score, 1,082 participants (17.2%) were identified as probable maladaptive daydreamers (MDers). A binary logistic regression revealed that compared to controls, probable MDers reported that during the COVID-19 lockdown they experienced higher levels of anxiety and depression, decreased online social relationships, and, surprisingly, stable or increased face-to-face social relationships. Given the peculiar characteristics of the pandemic context, these findings suggest that the exposure to the risk of contagion had probably exacerbated the tendency of probable MDers to lock themselves inside their mental fantasy worlds, which in turn may have contributed to further estrangement from online social relationships and support, thus worsening their emotional distress.
