Childhood maltreatment and non-suicidal self-injury in adolescent population: A systematic review and meta-analysis.

BACKGROUND: Non-suicidal self-injury (NSSI) is highly prevalent among adolescents. However, knowledge about the possible factors that might precede and influence its development remains scarce. OBJECTIVE: Our goal is to examine the impact of adverse childhood events, and more specifically of different types of childhood maltreatment (CM) in adolescent NSSI. This involves performing a systematic review and meta-analysis of the different CM subtypes (physical and emotional neglect, physical and emotional abuse, sexual abuse) in clinical and non-clinical samples of adolescents with NSSI. PARTICIPANTS AND METHODS: A digital search of the PsycInfo, PubMed and Web of Science platforms for articles published up to June 2022 was performed. The search terms were "self harm", "non-suicidal self-injury", "childhood maltreatment" and "adolescents". RESULTS: Forty-six articles that fit the research objectives were included in the study, which covered a total of 1,505,430 adolescents, of whom 560,337 belonged to the NSSI group, while 945,093 were in the control group. The results describe strong positive associations between all CM subtypes and NSSI, especially with emotional abuse (odds ratio [OR] 2.91, 95 % CI 2.37-3.56) and sexual abuse (OR 2.72, 95 % CI 2.12-3.48), in clinical and non-clinical samples of adolescents. CONCLUSIONS: The experience of CM, and especially emotional and/or sexual abuse, seems to be associated with a greater risk of developing NSSI in adolescence. Therefore, early identification and detection of children who have suffered or are suffering these forms of CM are of vital importance for instigating psychotherapeutic treatments that can minimize the risk of developing NSSI in adolescence.

Impact of education on knowledge, attitudes, and practices for gestational toxoplasmosis.

BACKGROUND: Toxoplasmosis is potentially avoidable, treatable, and curable by simple and direct preventive measures. Knowledge, attitudes, and practices (KAP) assessments concerning gestational toxoplasmosis were evaluated in a cohort of pregnant women from Armenia-Quindío (Colombia, South America). METHODS: This cross-sectional descriptive KAP-type study was performed with informed consent between October 2021 and March 2022. The intervention involved a ten-minute talk administered by prenatal clinic nurses to pregnant women. This took place in the public health clinic RedSalud and the private clinic Happy Maternity with a post-KAP survey after pregnancy. RESULTS: The findings of the initial KAP survey revealed that approximately 42.8 % of the 250 mothers surveyed had IgG anti-T. gondii antibodies present. A strong correlation was observed between a lower frequency of antibodies and a higher level of education. Following an educational intervention, 73 seronegative women demonstrated a significant improvement in their knowledge and behavior. Among the 111 mothers who received the intervention, 42 (37 %) were followed until delivery. Unfortunately, their level of compliance with prenatal serological follow-up was lower compared to previous historical records of cohort of mothers in the same health center during pre-pandemic periods. No seroconversion occurred, although the small number of cases makes the outcome inconclusive with respect to statistical significance. CONCLUSIONS: Education plays a crucial role in imparting valuable knowledge and fostering effective practices. It holds significant potential to prevent toxoplasmosis in pregnant seronegative mothers. Prenatal check-ups have proven to be a critical determinant in leveraging the benefits of education for seronegative mothers. Reporting and observed behaviors differed, identifying areas for improvement.

Do neuroticism and efficacy beliefs moderate the relationship between climate change worry and mental wellbeing?

BACKGROUND: Research on the nature and prevalence of phenomena like climate anxiety (or eco-anxiety) is increasing rapidly but there is little understanding of the conditions under which climate change worry becomes more or less likely to significantly impact mental wellbeing. Here, we considered two plausible moderators of the relationship between climate change worry and mental wellbeing: neuroticism and efficacy beliefs. METHODS: Analysis was conducted with survey data gathered in six European countries in autumn 2019. Participants were recruited from universities in the participating countries using opportunity sampling. RESULTS: We found that climate change worry is negatively related to mental wellbeing at any level of perceived efficacy. In contrast, climate change worry is only significantly related to mental wellbeing at low and average levels of neuroticism. High neuroticism appears to have a masking, rather than amplifying, role in the relationship between climate change worry and mental wellbeing. LIMITATIONS: The cross-sectional design of the study precludes verification of causal relationships among variables. The brief measure of neuroticism employed also did not allow for nuanced analysis of how different facets of neuroticism contribute to the observed interaction with climate change worry. Findings cannot be indiscriminately generalised to less privileged groups facing the worst impacts of the climate crisis. CONCLUSION: Our findings lend to a view that harmful impacts of climate change worry on mental wellbeing cannot simply be ascribed to dispositional traits like neuroticism. We advocate for interventions that tackle negative climate-related emotions as unique psychological stressors.

Sex Differences in Left Bundle Branch Area Pacing Versus Biventricular Pacing for Cardiac Resynchronization Therapy.

BACKGROUND: Women respond more favorably to biventricular pacing (BIVP) than men. Sex differences in atrioventricular and interventricular conduction have been described in BIVP studies. Left bundle branch area pacing (LBBAP) offers advantages due to direct capture of the conduction system. We hypothesized that men could respond better to LBBAP than BIVP. OBJECTIVES: This study aims to describe the sex differences in response to LBBAP vs BIVP as the initial cardiac resynchronization therapy (CRT). METHODS: In this multicenter prospective registry, we included patients with left ventricular ejection fraction ≤35% and left bundle branch block or a left ventricular ejection fraction ≤40% with an expected right ventricular pacing exceeding 40% undergoing initial CRT with LBBAP or BIVP. The composite primary outcome was heart failure-related hospitalization and all-cause mortality. The primary safety outcome included all procedure-related complications. RESULTS: There was no significant difference in the primary outcome when comparing men and women receiving LBBAP (P = 0.46), whereas the primary outcome was less frequent in women in the BIVP group than men treated with BIVP (P = 0.03). The primary outcome occurred less frequently in men undergoing LBBAP (29.9%) compared to those treated with BIVP (46.5%) (P = 0.004). In women, the incidence of the primary endpoint was 24.14% in the LBBAP group and 36.2% in the BIVP group; however, this difference was not statistically significant (P = 0.23). Complication rates remained consistent across all groups. CONCLUSIONS: Men and women undergoing LBBAP for CRT had similar clinical outcomes. Men undergoing LBBAP showed a lower risk of heart failure-related hospitalizations and all-cause mortality compared to men undergoing BIVP, whereas there was no difference between LBBAP and BIVP in women.

Human T-cell activation with Toxoplasma gondii antigens loaded in maltodextrin nanoparticles.

Toxoplasmosis is the most prevalent parasitic zoonosis worldwide, causing ocular and neurological diseases. No vaccine has been approved for human use. We evaluated the response of peripheral blood mononuclear cells (PBMCs) to a novel construct of Toxoplasma gondii total antigen in maltodextrin nanoparticles (NP/TE) in individuals with varying infectious statuses (uninfected, chronic asymptomatic, or ocular toxoplasmosis). We analyzed the concentration of IFN-γ after NP/TE ex vivo stimulation using ELISA and the immunophenotypes of CD4+ and CD8+ cell populations using flow cytometry. In addition, serotyping of individuals with toxoplasmosis was performed by ELISA using GRA6-derived polypeptides. Low doses of NP/TE stimulation (0.9 µg NP/0.3 µg TE) achieved IFN-γ-specific production in previously exposed human PBMCs without significant differences in the infecting serotype. Increased IFN-γ expression in CD4+ effector memory cell subsets was found in patients with ocular toxoplasmosis with NP/TE but not with TE alone. This is the first study to show how T-cell subsets respond to ex vivo stimulation with a vaccine candidate for human toxoplasmosis, providing crucial insights for future clinical trials.

Novel paradigm enables accurate monthly gestational screening to prevent congenital toxoplasmosis and more.

BACKGROUND: Congenital toxoplasmosis is a treatable, preventable disease, but untreated causes death, prematurity, loss of sight, cognition and motor function, and substantial costs worldwide. OBJECTIVES: We asked whether high performance of an Immunochromatographic-test (ICT) could enable accurate, rapid diagnosis/treatment, establishing new, improved care-paradigms at point-of-care and clinical laboratory. METHODS: Data were obtained in 12 studies/analyses addressing: 1-feasibility/efficacy; 2-false-positives; 3-acceptability; 4-pink/black-line/all studies; 5-time/cost; 6-Quick-Information/Limit-of-detection; 7, 8-acute;-chronic; 9-epidemiology; 10-ADBio; 11,12-Commentary/Cases/Chronology. FINDINGS: ICT was compared with gold-standard or predicate-tests. Overall, ICT performance for 1093 blood/4967 sera was 99.2%/97.5% sensitive and 99.0%/99.7% specific. However, in clinical trial, FDA-cleared-predicate tests initially caused practical, costly problems due to false-positive-IgM results. For 58 persons, 3/43 seronegative and 2/15 chronically infected persons had false positive IgM predicate tests. This caused substantial anxiety, concerns, and required costly, delayed confirmation in reference centers. Absence of false positive ICT results contributes to solutions: Lyon and Paris France and USA Reference laboratories frequently receive sera with erroneously positive local laboratory IgM results impeding patient care. Therefore, thirty-two such sera referred to Lyon's Reference laboratory were ICT-tested. We collated these with other earlier/ongoing results: 132 of 137 USA or French persons had false-positive local laboratory IgM results identified correctly as negative by ICT. Five false positive ICT results in Tunisia and Marseille, France, emphasize need to confirm positive ICT results with Sabin-Feldman-Dye-test or western blot. Separate studies demonstrated high performance in detecting acute infections, meeting FDA, CLIA, WHO REASSURED, CEMark criteria and patient and physician satisfaction with monthly-gestational-ICT-screening. CONCLUSIONS/SIGNIFICANCE: This novel paradigm using ICT identifies likely false positives or raises suspicion that a result is truly positive, rapidly needing prompt follow up and treatment. Thus, ICT enables well-accepted gestational screening programs that facilitate rapid treatment saving lives, sight, cognition and motor function. This reduces anxiety, delays, work, and cost at point-of-care and clinical laboratories. TRIAL REGISTRATION: NCT04474132, https://clinicaltrials.gov/study/NCT04474132 ClinicalTrials.gov.

Improved all-cause mortality with left bundle branch area pacing compared to biventricular pacing in cardiac resynchronization therapy: a meta-analysis.

BACKGROUND: Left bundle branch area pacing (LBBAP) has emerged as a physiological alternative pacing strategy to biventricular pacing (BIVP) in cardiac resynchronization therapy (CRT). We aimed to assess the impact of LBBAP vs. BIVP on all-cause mortality and heart failure (HF)-related hospitalization in patients undergoing CRT. METHODS: Studies comparing LBBAP and BIVP for CRT in patients with HF with reduced left ventricular ejection fraction (LVEF) were included. The coprimary outcomes were all-cause mortality and HF-related hospitalization. Secondary outcomes included procedural and fluoroscopy time, change in QRS duration, and change in LVEF. RESULTS: Thirteen studies (12 observational and 1 RCT, n = 3239; LBBAP = 1338 and BIVP = 1901) with a mean follow-up duration of 25.8 months were included. Compared to BIVP, LBBAP was associated with a significant absolute risk reduction of 3.2% in all-cause mortality (9.3% vs 12.5%, RR 0.7, 95% CI 0.57-0.86, p < 0.001) and an 8.2% reduction in HF-related hospitalization (11.3% vs 19.5%, RR 0.6, 95% CI 0.5-0.71, p < 0.00001). LBBAP also resulted in reductions in procedural time (mean weighted difference- 23.2 min, 95% CI - 42.9 to - 3.6, p = 0.02) and fluoroscopy time (- 8.6 min, 95% CI - 12.5 to - 4.7, p < 0.001) as well as a significant reduction in QRS duration (mean weighted difference:- 25.3 ms, 95% CI - 30.9 to - 19.8, p < 0.00001) and a greater improvement in LVEF of 5.1% (95% CI 4.4-5.8, p < 0.001) compared to BIVP in the studies that reported these outcomes. CONCLUSION: In this meta-analysis, LBBAP was associated with a significant reduction in all-cause mortality as well as HF-related hospitalization when compared to BIVP. Additional data from large RCTs is warranted to corroborate these promising findings.

Pseudomonas aeruginosa Bloodstream Infections Presenting with Septic Shock in Neutropenic Cancer Patients: Impact of Empirical Antibiotic Therapy.

This large, multicenter, retrospective cohort study including onco-hematological neutropenic patients with Pseudomonas aeruginosa bloodstream infection (PABSI) found that among 1213 episodes, 411 (33%) presented with septic shock. The presence of solid tumors (33.3% vs. 20.2%, p < 0.001), a high-risk Multinational Association for Supportive Care in Cancer (MASCC) index score (92.6% vs. 57.4%; p < 0.001), pneumonia (38% vs. 19.2% p < 0.001), and infection due to multidrug-resistant P. aeruginosa (MDRPA) (33.8% vs. 21.1%, p < 0.001) were statistically significantly higher in patients with septic shock compared to those without. Patients with septic shock were more likely to receive inadequate empirical antibiotic therapy (IEAT) (21.7% vs. 16.2%, p = 0.020) and to present poorer outcomes, including a need for ICU admission (74% vs. 10.5%; p < 0.001), mechanical ventilation (49.1% vs. 5.6%; p < 0.001), and higher 7-day and 30-day case fatality rates (58.2% vs. 12%, p < 0.001, and 74% vs. 23.1%, p < 0.001, respectively). Risk factors for 30-day case fatality rate in patients with septic shock were orotracheal intubation, IEAT, infection due to MDRPA, and persistent PABSI. Therapy with granulocyte colony-stimulating factor and BSI from the urinary tract were associated with improved survival. Carbapenems were the most frequent IEAT in patients with septic shock, and the use of empirical combination therapy showed a tendency towards improved survival. Our findings emphasize the need for tailored management strategies in this high-risk population.

Intracardiac Echocardiography-guided Left Atrial Appendage Occlusion.

Left atrial appendage occlusion (LAAO) is a suitable alternative to oral anticoagulant therapy to prevent stroke in patients with AF. Most procedures are performed under transoesophageal echocardiography (TOE) guidance, which facilitates transseptal puncture, reduces the risk of procedurerelated complications and provides an additional method for device selection and real-time monitoring during device deployment. However, TOE has significant shortcomings, including the need for general anaesthesia/deep sedation as well as a significant risk of procedure-related adverse events. More recently, intracardiac echocardiography has been proposed as an alternative to TOE guidance during LAAO procedures. In this review, we summarise the available evidence as well as providing a step-by-step approach for intracardiac echocardiography-guided LAAO.
