ABSTRACT

BACKGROUND: Temperament has been increasingly studied in relation to neurodevelopmental disorders, including Attention-Deficit/Hyperactivity Disorder (ADHD). This study examines the association between ADHD and affective temperament traits using the Temperament Scale of Memphis, Pisa, Paris, and San Diego (TEMPS-A) in a clinical outpatient sample in Beirut, Lebanon.

METHODS: This cross-sectional study included 2564 psychiatric outpatients aged 15 or older who completed the TEMPS-A. ADHD diagnosis was determined through clinical assessments based on the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) criteria. Statistical analyses included descriptive comparisons and multivariate logistic regression, with temperament trait scores categorized based on Lebanese population norms.

RESULTS: Participants had an average age of 38.53 years, with females comprising 52.3 % of the sample. Bivariate analyses showed ADHD was associated with higher cyclothymic (CT), hyperthymic (HT), and irritable (IT) temperament trait scores. After adjusting for age, gender, and comorbidities, only IT remained a significant risk factor for ADHD (OR = 2.73, 95 % CI: 1.23-6.09), while depressive temperament trait (DT) emerged as a protective factor (OR = 0.38, 95 % CI: 0.17-0.87).

CONCLUSION: Our findings highlight the complex relationship between temperament traits and ADHD. IT was a significant risk factor, while DT unexpectedly appeared protective. These results underscore the need for further investigation into temperament traits as a diagnostic and therapeutic consideration in ADHD.

ABSTRACT

BACKGROUND: Studies examining the association between maternal antibiotic use during pregnancy and the risk of childhood attention-deficit/hyperactivity disorder (ADHD) have yielded inconsistent results. This meta-analysis synthesizes available evidence to establish a more comprehensive understanding of this association.

METHODS: Observational studies published through October 2, 2024, were systematically searched from Cochrane Library, EMBASE, Web of Science, and PubMed databases. The Newcastle-Ottawa Scale was used to assess the quality of the included studies, and statistical analyses were performed using Stata version 15.0.

RESULTS: Nine studies encompassing 6,180,434 participants were included. Prenatal antibiotic exposure was associated with an increased risk of childhood ADHD (HR = 1.15; 95 % CI = 1.09-1.22, P < 0.0001; OR = 1.28; 95 % CI = 1.21-1.35, P < 0.001). Both mid-pregnancy (HR = 1.11; 95 % CI = 1.02-1.22, P = 0.282) and late-pregnancy (HR = 1.07; 95 % CI = 1.02-1.12, P = 0.521) antibiotic exposure was associated with an increased risk of ADHD. Repeated antibiotic exposures was associated with an increased risk further (twice: HR = 1.13; 95 % CI = 1.10-1.16, P = 0.856; ≥3 times: HR = 1.21; 95 % CI = 1.17-1.24, P = 0.166).

CONCLUSION: This analysis identified a link between maternal antibiotic use during pregnancy and an increased risk of childhood ADHD. Large-scale, multicenter, well-designed prospective studies are needed to confirm these findings and adjust for potential confounders in evaluating the relationship between prenatal antibiotic exposure and childhood ADHD.

ABSTRACT

OBJECTIVES: It would be prudent to consider the mental health of psychiatrists, who are entrusted with the responsibility of caring for our mental well-being. This study aimed to examine psychiatrists’ mental health and coping strategies.

METHODS: The study was conducted among 217 psychiatry residents and specialists in Turkey. Data was collected via online test programs. The participants were given a Sociodemographic Form, the Brief COPE inventory, the Generalized Anxiety Disorder-7 Scale (GAD-7), and the Patient Health Questionnaire-9 (PHQ-9).

RESULTS: The psychiatrists exhibited symptoms of poor mental health, with 35.5 % reporting anxiety and 12.4 % reporting depression. A statistically significant relationship was identified between burnout and depression and anxiety in the participants (p < 0.001, p < 0.001, respectively). A positive significant relationship was found between depression and emotion-focused coping style (R = 0.15, p = 0.025). Other statistically significant positive relationships were found between depression, anxiety and dysfunctional coping styles (R = 0.35, p < 0.001, R = 0.31, p < 0.001, respectively).

CONCLUSIONS: Psychiatrists should not neglect their mental health and that of their colleagues for the mental health of the community and should develop more functional coping strategies to deal with problems to carry the empathic burden of their profession.

ABSTRACT

BACKGROUND: Laughter has been associated with mental and physical health benefits, but longitudinal evidence on whether laughter in daily life protects against depression remain limited. This study aimed to examine whether the frequency of laughter in daily life is associated with the risk of depression onset among older adults.

METHODS: We analyzed data from 32,666 adults aged ≥65 years participating in the Japan Gerontological Evaluation Study, a three-wave cohort conducted over six-years. Frequency of laughter was assessed in 2019 using a self-administered questionnaire with response categories: “almost every day”, “1-5 days per week”, “1-3 days per month”, and “never or almost never”. Depression onset during 2016-2022 was defined using the Geriatric Depression Scale. We fitted a modified Poisson regression model to estimate the adjusted risk ratios and their 95 % confidence intervals (CIs), controlling potential confounders measured in 2016.

RESULTS: During follow-up, 4805 (14.7 %) participants developed depression. Compared to those who laughed almost every day, those who laughed 1-5 days per week had 1.25 (95 % CI 1.09-1.44) times, those who laughed 1-3 days per week had 1.26 (95 % CI 1.05-1.52) times, and those who laughed never had 1.49 (95 % CI 1.18-1.89) times higher risks of depression. A significant dose-response trend was observed (P for trend<0.001).

CONCLUSION: Lower frequency of laughter in daily life was associated with an increased risk of depression onset in older adults. These findings suggest that frequent laughter may play a role in depression prevention in later life.

ABSTRACT

BACKGROUND: An accurate understanding of protein requirements helps prevent health risks caused by deficiency. No statistical comparison exists between the nitrogen balance (NB) method, the standard method for estimating protein requirements, and the indicator amino acid oxidation (IAAO) method, which has been increasingly studied.

OBJECTIVE: To quantitatively compare the protein requirements of the NB and IAAO methods through meta-analyses.

METHODS: Studies estimating protein requirements in healthy individuals using the NB or IAAO methods were reviewed. First, previous reviews were systematically searched to identify original NB articles up to 2012 and IAAO articles up to 2023 from their references. Original articles published after each review’s search period, up to January 11, 2025, were systematically searched using PubMed and Ichushi-Web. Manual searches were performed through citation tracking of included literature and gray literature. This study followed PRISMA guidelines. Differences in protein requirements between assessment methods were compared using Welch’s t-test.

RESULTS: A total of 43 NB articles (777 participants) and 17 IAAO articles (186 participants) were included. In non-athletes, protein requirements were significantly higher by 36% with IAAO (mean: 0.88 g/kg/day; 95% confidence interval (CI): 0.85, 0.90) than with NB (mean: 0.64 g/kg/day; 95% CI: 0.61, 0.68). In athletes, protein requirements were significantly higher by 27% with IAAO (mean: 1.61 g/kg/day; 95% CI: 1.44, 1.78) than with NB (mean: 1.27 g/kg/day; 95% CI: 1.06, 1.47). In non-athletes, IAAO values remained significantly higher than NB values across age and sex subgroups.

CONCLUSIONS: The protein requirements calculated using the IAAO method were approximately 30% higher than those obtained using the NB method. The quantitative findings of this study provide important information for scientific consideration of protein requirements. REGISTRY AND REGISTRY NUMBER FOR SYSTEMATIC REVIEWS OR META-ANALYSES: This study was registered with PROSPERO as CRD42025636735.

ABSTRACT

PURPOSE: This study aimed to investigate the prevalence and anatomical patterns of temporal bone pneumatisation surrounding the internal acoustic meatus (IAM), specifically across its three anatomical regions: the porus acusticus internus (medial opening), the proper IAM (tubular midportion), and the fundus (lateral end). A secondary objective was to evaluate the association between pneumatisation and the thickness of the overlying tegmen in each region.

METHODS: A total of 160 IAMs (80 patients, bilateral assessment) were analyzed using cone-beam computed tomography (CBCT). The IAM was anatomically subdivided into the porus, proper IAM, and fundus. Pneumatisation was assessed separately for each region’s superior (tegmen), inferior, anterior, and posterior bony walls. Linear measurements of tegmen thickness were obtained and compared between pneumatised and non-pneumatised regions. Statistical analyses included Shapiro-Wilk normality tests, Levene’s variance equality test, and independent samples t-tests.

RESULTS: Complete superior wall pneumatisation was observed in 23.8% of right sides and 22.5% of left sides. Inferior wall pneumatisation was absent bilaterally in 52.5% of cases, while anterior wall involvement was noted in fewer than 17% of cases. Posterior wall pneumatisation was absent in 80.0% (right) and 75.0% (left) sides. Pneumatised regions demonstrated significantly greater tegmen thickness across all areas (p < 0.001 in most cases). Gender-based analyses were conducted.

CONCLUSION: IAM-adjacent pneumatisation most often involves the superior wall and correlates with greater tegmen thickness, supporting targeted imaging for safer skull-base surgery and updating clinicians’ understanding of this region.

ABSTRACT

Lysophosphatidylcholine (LPC) has been the subject of research for many years, but its role in lipid turnover is still not fully understood, neither its role in cancer development and progression. A crucial aspect in LPC research is its efficient and fast extraction from plasma and tissues to use LPC as a biomarker in clinical settings. The extraction methods commonly in use like Bligh & Dyer require the use of toxic halogenated solvents and are time consuming due to multiple extraction steps and subsequent solvent evaporation. In this study, a new, salt-assisted one-step extraction protocol, which avoids halogenated solvents, is presented. Saturated ammonium acetate solution was used as a salt component and acetonitrile:isopropanol (2.5:1 v/v) as eluent. The new extraction is characterized by its simplicity, robustness and short total extraction time of 18 minutes. For validation according to the ICH M10 guideline for bioanalytical method validation, LPC species extracted from plasma were quantified by LC-MS/MS, using LPC 19:0 as internal standard. In addition to these advantages, the new extraction procedure showed a slightly but statistically significant better recovery compared to Bligh & Dyer (93.2% vs. 87.5%; p<0.05; n = 5), as shown by a t-test. The applicability of the new method was demonstrated in a pilot study, in which the plasma of 15 healthy volunteers was analyzed for its content of various LPC types.

ABSTRACT

BACKGROUND: Current recommendations for a prophylactic (primary prevention) implantable cardioverter defibrillator (ICD) in patients with both ischemic and non-ischemic heart failure with reduced ejection fraction (HFrEF) originate from clinical trials conducted in selected patients over 20 years ago that showed an overall statistically significant survival benefit associated with a primary prevention ICD in the range of 23%-34%. The recent introduction of angiotensin receptor-neprilysin inhibitors [ARNI] and sodium glucose co-transporter 2 inhibitors [SGLT2i]) was shown to further reduce the risk of sudden cardiac death (SCD) in patients with HFrEF. Thus, there is an unmet need appropriately designed comparative effectiveness clinical trials aimed to reassess the survival benefit of a primary prevention ICD in contemporary patients with HFrEF.

METHODS: The Comparative Effectiveness of ICD Versus Non-ICD Therapy in Contemporary Heart Failure Patients at a Low Risk for Arrhythmic Death (CONTEMP-ICD) trial is a prospective, multicenter, open-label, randomized-controlled trial; enrolling 3290 participants with HFrEF who are treated with optimal stable GDMT and are eligible for a primary prevention ICD, but have a lower predicted risk of life-threatening ventricular tachyarrhythmia (VTA) than non-arrhythmic mortality. Enrolled participants will be randomized to Non-ICD vs. ICD treatment arms and will be followed over an average period of 3.5 years. The Specific Aims of the proposed clinical trial are to: 1) Compare the risk of all-cause mortality of Non-ICD vs. ICD in HFrEF patients who have a lower predicted risk of VTA than non-arrhythmic mortality per the MADIT-ICD Benefit Score; 2) Evaluate whether Non-ICD vs. ICD is associated with improved survival free of major CV events in patients with HFrEF who are at a lower predicted arrhythmic risk; 3) Assess healthcare utilization and quality of life implications of Non-ICD vs. ICD management approaches in HFrEF patients who are at a lower predicted arrhythmic risk; and 4) Determine the effect of Non-ICD vs. ICD management on all-cause mortality in prespecified subgroups.

CONCLUSIONS: We hypothesize that, in patients with HFrEF who are at a lower predicted arrhythmic risk, Non-ICD vs. ICD is non-inferior with respect to the primary endpoint of all-cause mortality and superior with respect to the secondary endpoint of survival free of major CV events.

ABSTRACT

Escherichia coli O157:H7 is a significant foodborne pathogen with global public health implications. This study, conducted from December 2022 to July 2023 in Hawassa and Yirgalem, Sidama Region, Ethiopia, assessed the prevalence, molecular identification, and antimicrobial resistance of E. coli O157:H7 in animal-derived foods. A total of 298 samples including beef, raw milk, and fish were analyzed using culture methods, biochemical identification, and PCR. The overall prevalence of E. coli O157:H7 was 3.7%, with isolation rates of 6.25% in fish and 5.6% in beef; no isolates were found in milk samples (p = 0.036). Notably, meat from butcher shops exhibited a higher contamination rate (7.6%) compared to abattoir samples (3.4%), though this difference was not statistically significant (p = 0.445). Among fish samples, Nile Tilapia had a higher isolation rate (8.1%) than African Catfish (3.7%), with fish skin showing greater contamination (8.6%) than muscle tissue (3.4%). All E. coli O157:H7 isolates were susceptible to most tested antibiotics; however, resistance was observed against amoxicillin (81.8%), streptomycin (45.5%), and clindamycin (100%). Additionally, 45.5% of isolates exhibited multidrug resistance with an multidrug resistance (MDR) index of 0.27, though none produced extended-spectrum beta-lactamases (ESBL). These findings underscore the necessity for stringent hygiene practices and effective monitoring of animal-derived foods to mitigate public health risks.

ABSTRACT

INTRODUCTION: Migraine headache not only is associated with high levels of suffering but also represents a considerable socioeconomic challenge. It is linked to various psychological and physiological impairments, including sensorimotor and somatosensory dysfunction, like those observed in other persistent pain syndromes. This study aims to determine whether individuals with high-frequency episodic (HFEM) or chronic migraine (CM) exhibit differences in somatosensory perception compared to healthy individuals and to explore potential correlations with neuropsychological features.

METHODS: Using a cross-sectional design, we assessed individuals with HFEM or CM (n = 45) and healthy controls (n = 25) using quantitative sensory testing (QST), conditioned pain modulation testing and neuropsychological questionnaires such as the Central Sensitization Inventory (CSI) and the Toronto Alexithymia Scale (TAS-20).

RESULTS: Data from 45 participants (39 females) with HFEM or CM and a healthy control group of 25 individuals (21 female) were analysed. Median (range) number of monthly headache days of was 12.3 (6) in the migraine group. Statistically significant differences were found only in the assessment of central sensitization (p < 0.0010) but not for QST parameters. Correlations with QST parameters were generally weak, only the wind-up ratio (WUR) showing weak to moderate monotonic associations with both emotion- and somatosensory-associated parameters.

CONCLUSION: Overall, the results provided no evidence of significant differences between the migraine and healthy control groups. The lack of significant differences might be attributed to methodological limitations. However, the comprehensive and standardized implementation of QST strictly following the protocol of the German Research Network on Neuropathic Pain (DFNS), the selection of robust questionnaires, uniform diagnostic criteria and rigorous statistical analysis represent methodological strengths and support the validity of the results. Nevertheless, these findings, which partly contrast with existing literature, may reflect limitations of the sample and methodology and should be interpreted with caution.
