To determine and compare the intraoperative durability of 4 major surgical glove brands.

This study is a randomized open-label clinical trial in which surgical gloves from 4 manufacturers are randomized to 5 surgical subspecialty study groups: (1) orthopedic surgery, (2) neurosurgery, (3) colorectal surgery, (4) trauma or acute general surgery, and (5) cardiac and plastic surgeries. The study was divided into 10 periods, with a cross-over design, and was conducted at a tertiary care academic medical center. Participants were licensed and certified physicians, physicians-in-training, scrub nurses, or technicians working within the sterile field.

Participants from each study group were randomly assigned to 1 of 4 surgical glove manufacturer types and subsequently rotated through the other 3 glove brands such that each participant acted as their own control in the sequential cross-over design.

The primary outcome was to determine and compare the intraoperative failure rate of Biogel® Sterile Surgical undergloves against sterile surgical undergloves from 3 other manufacturers, both as a combined competitor group and individually.

There were no differences between brands with respect to the primary outcome of underglove intraoperative failures. Brand 1 wearers were slightly more likely to detect glove failures when they occurred.

The durability of surgical gloves intraoperatively is similar across 4 major glove manufacturers. Detection of intraoperative failures is infrequent, though specific glove characteristics may promote enhanced detection. Recognition of glove perforations intraoperatively is important in the maintenance of a maximally sterile field.

We assessed the effectiveness of heterologous vaccination strategy in immunocompromised individuals regarding COVID-19 outcomes, comparing it to homologous approaches.

Systematic literature review/meta-analysis.

We searched PubMed, CINAHL, EMBASE, Cochrane Central Register of Controlled Trials, Scopus, and Web of Science from January 1, 2020 to September 29, 2023. We included studies that evaluated the heterologous vaccination strategy on immunocompromised individuals through outcomes related to COVID-19 (levels of anti-SARS-CoV-2 spike protein IgG, neutralizing antibodies, symptomatic COVID-19 infection, hospitalization, and death) in comparison to homologous schemes. We also used random-effect models to produce pooled odds ratio estimates. Heterogeneity was investigated with I2 estimation.

Eighteen studies met the inclusion criteria for this systematic review. Fourteen of them provided quantitative data for inclusion in the meta-analysis on vaccine response, being four of them also included in the vaccine effectiveness meta-analysis. The vaccination strategies (heterologous vs homologous) showed no difference in the odds of developing anti-SARS-CoV-2 spike protein IgG (odds ratio 1.12 [95% Cl: 0.73–1.72]). Heterologous schemes also showed no difference in the production of neutralizing antibodies (odds ratio 1.48 [95% Cl: 0.72–3.05]) nor vaccine effectiveness in comparison to homologous schemes (odds ratio 1.52 [95% CI: 0.66–3.53]).

Alternative heterologous COVID-19 vaccinations have shown equivalent antibody response rates and vaccine effectiveness to homologous schemes, potentially aiding global disparity of vaccine distribution.

With the rise of online references, podcasts, webinars, self-test tools, and social media, it is worthwhile to understand whether textbooks continue to provide value in medical education, and to assess the capacity they serve during fellowship training.

A prospective mixed-methods study based on surveys that were disseminated to seven paediatric cardiology fellowship programmes around the world. Participants were asked to read an assigned chapter of Anderson’s Pediatric Cardiology 4th Edition textbook, followed by the completion of the survey. Open-ended questions included theming and grouping responses as appropriate.

The survey was completed by 36 participants. When asked about the content, organisation, and utility of the chapter, responses were generally positive, at greater than 89%. The chapters, overall, were rated relatively easy to read, scoring at 6.91, with standard deviations plus or minus 1.72, on a scale from 1 to 10, with higher values meaning better results. When asked to rank their preferences in where they obtain educational content, textbooks were ranked the second highest, with in-person teaching ranking first. Several themes were identified including the limitations of the use of textbook use, their value, and ways to enhance learning from their reading. There was also a near-unanimous desire for more time to self-learn and read during fellowship.

Textbooks are still highly valued by trainees. Many opportunities exist, nonetheless, to improve how they can be organised to deliver information optimally. Future efforts should look towards making them more accessible, and to include more resources for asynchronous learning.

Fear learning is a core component of conceptual models of how adverse experiences may influence psychopathology. Specifically, existing theories posit that childhood experiences involving childhood trauma are associated with altered fear learning processes, while experiences involving deprivation are not. Several studies have found altered fear acquisition in youth exposed to trauma, but not deprivation, although the specific patterns have varied across studies. The present study utilizes a longitudinal sample of children with variability in adversity experiences to examine associations among childhood trauma, fear learning, and psychopathology in youth.

The sample includes 170 youths aged 10–13 years (M = 11.56, s.d. = 0.47, 48.24% female). Children completed a fear conditioning task while skin conductance responses (SCR) were obtained, which included both acquisition and extinction. Childhood trauma and deprivation severity were measured using both parent and youth report. Symptoms of anxiety, externalizing problems, and post-traumatic stress disorder (PTSD) were assessed at baseline and again two-years later.

Greater trauma-related experiences were associated with greater SCR to the threat cue (CS+) relative to the safety cue (CS−) in early fear acquisition, controlling for deprivation, age, and sex. Deprivation was unrelated to fear learning. Greater SCR to the threat cue during early acquisition was associated with increased PTSD symptoms over time controlling for baseline symptoms and mediated the relationship between trauma and prospective changes in PTSD symptoms.

Childhood trauma is associated with altered fear learning in youth, which may be one mechanism linking exposure to violence with the emergence of PTSD symptoms in adolescence.

The Korean Basketball League(KBL) holds an annual draft to allow teams to select new players, mostly graduates from the elite college basketball teams even though some are from high school teams. In sports games, many factors might influence the success of an athlete. In addition to possessing excellent physical and technical factors, success in a sports game is also influenced by remarkable psychological factors. Several studies reported that elite sports players can control their anxiety during competition, which may lead to better performance. In particular, the temperament and characteristics of players have been regarded as crucial determinants of the player’s performance and goal. In this regard, numerous studies suggest that personality is considered to be an important predictor of long-term success in professional sports

Based on previous reports and studies, we hypothesized that physical status, temperament and characteristics, and neurocognitive functions of basketball players could predict the result of KBL draft selection. Especially, temperament and characteristics were associated with the result of KBL selection. The basketball performances including average scores and average rebound were associated with emotional perception and mental rotation.

We recruited the number of 44 college elite basketball players(KBL selection, n=17; Non-KBL selection, n=27), and the number of 35 age-matched healthy comparison subjects who major in sports education in college. All participants were assessed with the Temperament and Character Inventory(TCI), Sports Anxiety Scales(SAS), Beck Depression Inventory(BDI), Perceived Stress Scale (PSS-10), Trail Making Test(TMT), and Computerized Neuro-cognitive Test(CNT) for Emotional Perception and Mental Rotation.

Current results showed that physical status, temperament and characteristics, and Neurocognitive functions of college basketball players could predict the KBL draft selection. Among temperament and characteristics, novelty seeking and reward dependence were associated with KBL draft selection. The basketball performances including average scores and average rebound were associated with emotional perception and mental rotation.

In order to be a good basketball player for a long time, it was confirmed that temperamental factors and Neurocognitive factors were very closely related. Furthermore, it is also judged that these results can be used as basic data to predict potential professional basketball players.

The bidirectional relationship between the effects of sleep and exercise is often underappreciated. We aim to explore the bidirectional relationship of sleep and exercise. We further discuss the prominence of poor sleep in both the athletic and general population and understand the underlying mechanisms of interdependencies between the two. The goal is to illuminate practical implications to improve both areas and optimize physical and mental health.

• - To explore the bidirectional relationship between sleep and exercise

• - To understand how exercise can counterbalance the adverse metabolic consequences of sleep deprivation.

We conducted a systemic literature review from Pubmed, Scopus, and PsychINFO using the search terms: “(exercise) and (sleep),” “(exercise performance) and (sleep),” “(sleep quality) and (exercise).” We included original studies in English conducted on age groups 18 years and older.

Data from 31 studies shows that a significant number of athletes experience poor sleep quality and daytime sleepiness. 68.5% of Qatar Stars League soccer players and 61% of collegiate athletes in NCAA institutions report daytime fatigue several times a week. Most common causes include overtraining, hectic travel schedules, and sleeping in unfamiliar settings. Studies confirm athletes often sleep less before intense training or competitions. Sleep deficiency may lead to reduced muscular strength and endurance, mood changes, increased perceived effort, impaired cognitive processing, and diminished motor skills. Athletes averaging less than 8 hours of sleep nightly were 1.7 times more prone to injuries. Physiologically, sleep loss alters ventilation, plasma lactate concentration, hormone secretion, and inflammatory responses, hinders muscle glycogen restoration. Extended sleep restriction decreases testosterone levels, which influence muscle mass, energy, bone strength, and more. On the contrary, exercise may counter adverse metabolic impacts of sleep deprivation. High-intensity interval exercise (HIIE) has shown to nullify negative metabolic effects of sleep deprivation, suggesting exercise’s protective potential.

Sleep and exercise are fundamental to maintaining physical, mental, emotional, and spiritual health. The bidirectional, interdependent relationship can be best utilized by the providers to optimize overall well being. The critical impact of adequate sleep, particularly among athletes, is frequently underestimated. Poor sleep can detrimentally affect performance, amplify injury risks, and disrupt physiological functions, yet contemporary lifestyles often downplay its significance. It is important for healthcare professionals to emphasize a balanced approach to optimize these vital aspects. Continued research can offer strategies that benefit athletes and the broader populace, aiming to uplift daily life functionality.

Suicide has a complex relationship with several factors, and it is known that identifying high-risk groups of suicide and managing crisis in advance can help prevent suicide. Moreover in a previous study, it showed that people with chronic diseases often suffer from psychological difficulties such as depression and anxiety, which can influence one to commit suicide. Based on many studies about the relationship between diabetes and depression, 10% of diabetic patients experience major depression, and diabetic patients experience twice as much depression as the general population. But, there are few studies examining the relationship between diabetes and suicide risk, and most of them were targeted for type 1 diabetes only.

The objectives of this study were to investigate the suicide risk in diabetic patients, and evaluate the suicide risk varies by the duration of diabetes, using a large population sample in South Korea

Using the 2019 Korea National Health and Nutrition Examination Survey data, 6,296 adults (aged 19 years or older) were included. Suicidal ideation, suicidal plan, and suicidal behavior of diabetic patients were compared with the general population. After classifying the patients into ≤ 1 year, 2 to 9 years, and 10 years ≤ for the duration of diabetes, we evaluated the relationship between the duration of diabetes and the risk of suicide.

Diabetic patients had higher prevalence of suicidal ideation (9.1%, P<0.001) and suicidal plan (3.6%, P<0.001) than general population. After adjusting for potential confounding factors, suicidal plan (aOR = 3.011, 95% CI = 1.392-6.512) was significantly associated with diabetes. In the 2 to 9 year group of diabetes, we found an increase in risk of suicidal ideation (aOR=2.068, 95% CI=1.219-3.510), suicidal plan (aOR=3.640, 95% CI=1.592-8.320), and suicidal behavior (aOR=6.222, 95% CI=1.759-22.008) after adjusting covariates. However, increase in suicide risk was not observed in the ≤1 year and 10 years ≤ groups after diagnosis of diabetes.

In adults, diabetes is associated with increase in suicide risk. Suicide risk in diabetic patients shows an ‘inverted U-shaped’ depending on the duration of diabetes.

Sleep disturbance, particularly insomnia, is prevalent across various mental health disorders. While it is a common sign in mood disorders, emerging evidence suggests that insomnia might act as a precursor or an early sign of psychosis. Our case report and literature review emphasize the importance of evaluating sleep disturbances in the diagnosis and management of mental disorders.

• - To explore potential neurobiological underpinnings linking sleep disturbances to psychosis onset.

• - To advocate for the importance of early identification and intervention for sleep disturbances in the broader context of preventing or managing psychotic disorders.

We present a case describing a young patient’s first episode of psychosis, which was masked by an initial presentation of insomnia. Additionally, we conducted a review of the relationship between sleep disturbances and psychosis, with a comprehensive literature search from Pubmed, Scopus and psychINFO.

A 20-year-old African-American male with a history of poor sleep was initially diagnosed with Major Depressive Disorder. He was treated with Bupropion, Quetiapine, and Trazodone. However, he later presented with worsening depression, odd behavior, and signs of disorganization, suggestive of a psychotic episode. After switching his medication to Risperidone 4mg twice daily, the patient’s sleep and other symptoms markedly improved. Through our literature review, we identified that sleep disturbances, especially insomnia, can be a risk factor for developing psychosis. While a cross-sectional study recorded one-fourth of their study population experiencing First Episode Psychosis (FEP) with clinical insomnia, another study reported close to 80% of their study sample with early psychosis suffering from a minimum of one sleep disorder; insomnia and nightmare disorder being the most frequent. A large sample longitudinal analysis lasting one year also observed patients with sleep disorders to be twice at risk of onset and persistence of psychotic episodes. A growing body of evidence also suggests that structural brain abnormalities and neural development alterations in the early stages of psychosis may lead to sleep disturbances and subsequent psychotic symptoms. Findings suggest that thalamic dysfunction may in particular contribute to sleep spindle deficits and altered EEG microstate dynamics. These deficits are unrelated to antipsychotic medication exposure, and are also not observed in patients with other psychiatric illnesses.

While the correlation between sleep disorders and psychosis has been well-established for decades, very limited literature is available on the role of sleep in FEP. Recognizing and treating sleep disturbances is pivotal in managing psychiatric disorders, including psychosis. Thus, a comprehensive evaluation of sleep issues in patients presenting with psychiatric symptoms is imperative for accurate diagnosis and management.

While technology continues to evolve and the prevalence of screen-based activities is rising, limited studies have investigated the effect of various types of screen time on youth behavioural problems. Further, the influence of mindfulness intervention programs on behavioural problems beyond hyperactivity is largely understudied.

This study aims to address a research gap by examining the associations between four types of screen time and hyperactivity and conduct problems among community youth during the pandemic. The current study also aimed to investigate the efficacy of a mindfulness-based intervention in reducing hyperactivity and conduct problems.

Community youth aged 12-25 from Ontario, Canada, were recruited between April 2021 and April 2022 (n=117, mean age=16.82, male=22%, non-White=21%). The Mindfulness Ambassador Program, a structured, 12-week, evidence-based intervention program, was offered live, online and led by two MAP-certified facilitators. We conducted linear regression analyses using pre-intervention data to examine the unique association between the four types of screen time and behavioural problems (hyperactivity and conduct problems). The efficacy of the MAP on adolescent hyperactivity and conduct problems was examined considering the three survey time points (pre-, post-, and follow-up) using a series of linear regression models utilizing the Generalized Least Squares (GLS) Maximum Likelihood (ML), unstructured model.

The average score for conduct problems was classified within the normal range, while the average score for hyperactivity was considered borderline at baseline. More than 5 hours of playing video games were significantly associated with increased conduct problems [β= -1.75, 95% CI=-0.20 – 3.30, p=0.03]. Accounting for age, sex, baseline mental health status, and screen time, the mindfulness intervention program significantly contributed to decreased hyperactivity at post-intervention compared to the baseline [β=-0.49, 95% CI=-0.91 to -0.08, p=0.02]. It was maintained at follow-up [β=-0.64, 95% CI=-1.26 to -0.03, p=0.04].

Our findings suggest an adverse impact of excessive video gaming on behavioural problems among community youth and confirm that the trend remains the same. Considering the simplicity, brevity, non-invasive nature and other mental health benefits of the mindfulness intervention, we argue that the results are promising and worthy of further study and larger-scale implementation. Clinicians, parents, and educators should work collaboratively to provide developmentally appropriate strategies to moderate screen time spent on video games among youth.

Despite the unclear nature of catatonia, the treatment response of catatonia to benzodiazepines is widely known for its typical, dramatic recovery. The neurobiological correlates of this phenomenon regarding specific receptors and neurotransmitters are unclear, as are the potential treatment options. This is important to consider when the most commonly recommended treatments of catatonia with Lorazepam or Electroconvulsive Therapy (ECT) are unavailable or unsuccessful. In this report, we describe a case of severe, malignant catatonia and psychosis mostly unresponsive to Lorazepam during two different hospitalizations, but with eventual return to baseline after successful treatment with Valproate.

• - To describe a unique case of malignant catatonia that was unresponsive to Lorazepam

• - To illustrate the potential utility of Valproate as an alternative treatment strategy for catatonia

This is a case report.

A 19-year-old Hispanic male presented to our hospital initially with family reports of severe and sudden depression with bizarre behavior. Prior to this admission, the patient had been discharged recently from another tertiary hospital following a 2-week admission for severe catatonia. Chart review from that admission scored the patient’s Bush-Francis Catatonia Rating Scale (BFCRS) at 16, which remained mostly unchanged after numerous additional intramuscular doses and standing oral doses of Lorazepam, with a reduction of BFCRS the next day of only 2. During the patient’s admission at our hospital, the patient endorsed bizarre, guilt-related delusions, and his catatonia was more severe and malignant with a BFCRS of 19, with tachycardia and diaphoresis. The patient was initially given a total of seven doses of a mix of intramuscular and oral Lorazepam (total 18mg), with a minimal 2-point reduction in BFCRS. As ECT was unavailable, Lorazepam was discontinued in favor of a trial of oral Valproate 500mg twice daily, and after his catatonia subsided (with a serum level of 60.8), he was started on oral Risperidone 0.5mg once at night, titrated up to 3mg twice daily, and eventually returned to baseline as confirmed by his family members.

The treatment of catatonia with Lorazepam is usually reliable and has been found to be up to 80% effective, but when the recommended use of benzodiazepines and ECT fail or are unavailable, there are few studies exploring the viability of alternative treatment options. With the use of Valproate, previous studies have shown it can treat even severe catatonia (KrÜger, J Neuropsychiatry 2001; 13:303-304), or can actually be its cause (Lauterbach, Neuropsychiatry, Neuropsychology, and Behavioral Neurology. 1998 Jul;11(3):157-163). As such, this case report highlights the importance of exploring alternative treatments for catatonia, including Valproate, in order to better tailor the management of this unique syndrome.

Anxiety disorders are one of the most common mental disorders, yet only less than 20% of people with anxiety disorders receive adequate treatment. Digital interventions for anxiety disorders can potentially increase access to evidence-based treatment. However, there is no comprehensive meta-analysis study that covers all modalities of digital interventions and all anxiety disorders.

A preliminary meta-analysis was conducted to examine the treatment efficacy of digital interventions [e.g., virtual reality (VR)-, mobile application-, internet-based interventions] for anxiety disorders and to identify potential moderators that may lead to better treatment outcomes.

We searched Embase, PubMed, PsycINFO, Web of Science, and the Cochrane Library for randomized controlled trials examining the therapeutic efficacy of digital interventions for individuals with anxiety disorders from database inception to April 18, 2023. Search keywords were developed by combining the PICOS framework and MeSH terms. Data screening and extraction adhered to PRISMA guidelines. We used a random-effects model with effect sizes expressed as Hedge’s g. The quality of the studies was assessed using the Revised Cochrane risk-of-bias tool for randomized trials (RoB 2). The study protocol was registered in PROSPERO on April 22, 2023 (CRD42023412139).

A systematic literature search identified 19 studies with randomized controlled trials (21 comparisons; 1936 participants) with high overall heterogeneity (Q = 104.49; P < .001; I2 = 80.9%). Digital interventions reduced anxiety symptoms with medium to large effect sizes (g = 0.78; 95% CI: 0.55-1.02; P < .001), with interventions for specific phobia showing the largest effect size (n = 6; g = 1.22; 95% CI: 0.51-1.93; P < .001). VR-based interventions had a larger effect size (n = 6; g = 0.98; 95% CI: 0.39-1.57; P < .001) than mobile- or internet-based interventions, which had medium effect sizes. Meta-regression results exhibited that effect sizes of digital interventions were associated with the mean age of participants (β = 0.04; 95% CI: 0.02-0.06; P < .001).

The results of this study provide evidence for the efficacy of digital interventions for anxiety disorders. However, this also suggests that the degrees of effectiveness in reducing anxiety symptoms can be moderated by the specific diagnosis, the modalities of digital technologies, and mean age, implying that the application of digital interventions for anxiety disorders should be accompanied by personalized guidance.

This study investigates the effects of transcranial direct current stimulation (tDCS) on food craving improvement and changes in brain function associated with craving in overweight and obese subjects.

Food craving disregards the homeostatic mechanisms related to appetite and nullifies the rewarding effects of food, directly contributing to body weight and eventually leading to obesity. In this study, we aim to explore the effects of transcranial direct current stimulation (tDCS) on food craving improvement and changes in brain function associated with craving by conducting a total of 10 sessions of tDCS over a period of 2 weeks on overweight and obese subjects.

A total of 86 patients who were overweight or obese (BMI ≥ 23 kg/m2) during the study period were included. The tDCS montage involved placing the anode over the left and the cathode over the right DLPFC. Weight, BMI, neuropsychological variables, and food craving-related variables were assessed. We measured absolute and relative EEG power in 19 channels and analyzed QEEG according to the following frequency ranges: delta (1–4 Hz), theta (4–8 Hz), alpha (8–12 Hz), beta (12–25 Hz), high beta (25–30 Hz), and gamma (30–80 Hz).

After the application of tDCS, there was no significant reduction observed in weight and BMI. However, all measures related to food and eating showed a decrease in the intensity of cravings, and there was also a significant reduction in depression, anxiety, and perceived stress. In quantitative EEG analysis, an increase in theta waves was observed in the left frontal area (F7 and F3), an increase in alpha waves in the right parietal area (P4), and a decrease in beta waves in the frontal area (FP2) and occipital area (O1).

This study investigated the effects of tDCS on food craving in overweight and obese individuals, and it was found that there were improvements in psychological factors such as depression and anxiety. Additionally, using quantitative EEG, neurophysiological changes were observed, including an increase in theta waves and a decrease in beta waves.
