Aluminium adjuvants in vaccines and potential health effects: systematic review

May 6, 2026

The authors conducted a systematic review to assess the potential health effects of aluminium adjuvanted vaccines by analyzing human studies on health outcomes following vaccination. Their findings indicate no causal associations between these vaccines and serious or long-term health issues, with only minor and infrequent localized reactions observed. The review highlights the need for higher quality research due to the predominance of methodologically limited studies in the existing literature.

Accelerated continuous theta burst stimulation targeting left primary motor cortex for children with autism spectrum disorder: multicentre randomised sham controlled trial

Apr 29, 2026

The authors aimed to evaluate the efficacy and safety of a five-day accelerated continuous theta burst stimulation (a-cTBS) protocol in enhancing social communication abilities in children with autism spectrum disorder. The multicentre randomized sham-controlled trial found that a-cTBS significantly reduced social communication impairments and improved language skills compared to the sham treatment, with a favorable safety profile. These results suggest that a-cTBS could be a promising therapeutic option for this population.

Benzodiazepine or Z-hypnotic use during pregnancy and risk of psychiatric disorders in children: population based cohort study

Apr 29, 2026

The authors aimed to investigate the relationship between prenatal exposure to benzodiazepines or Z-hypnotics and the risk of psychiatric disorders in children. Their population-based cohort study found no significant increase in psychiatric disorders among children exposed to these medications during pregnancy after controlling for familial factors, although some subgroup analyses suggested modestly elevated risks in specific contexts, particularly with exposure during the latter half of pregnancy. Overall, the findings indicate that while there may be slight risks in certain situations, the general association appears minimal.

Home environment conditions during childhood and psychosocial outcomes across three generations in Sweden: population based adoption-discordant sibling comparison study

Apr 22, 2026

The authors aimed to investigate whether early adoption into families with favorable home environments can reduce long-term psychosocial risks and provide intergenerational benefits for individuals born to parents with psychiatric or behavioral issues. Their findings indicate that adopted individuals exhibited lower rates of psychiatric disorders, criminal convictions, and social welfare dependency, along with higher educational attainment and cognitive skills, with some positive effects also observed in their offspring. This study underscores the potential of improving childhood environments to alleviate intergenerational disadvantages.

Advances in the drug treatment of Alzheimer's disease: pathophysiology and mechanisms of action

Apr 21, 2026

The authors review recent advances in the drug treatment of Alzheimer's disease, aiming to address the multifactorial nature of the disorder, including amyloid beta and tau pathology, neuroinflammation, and metabolic dysfunction. They highlight the need for combination therapies that target these diverse mechanisms to improve patient outcomes, as current anti-Aβ treatments do not fully prevent cognitive decline. The paper discusses emerging multimodal strategies in late-stage development that could enhance treatment efficacy and quality of life for patients.

Prenatal exposure to buprenorphine or methadone and adverse neurodevelopmental outcomes: population based cohort study

Apr 15, 2026

This study aimed to compare the incidence of neurodevelopmental disorders in children with prenatal exposure to buprenorphine versus methadone. Analyzing data from over 18,000 pregnancies, the authors found no significant increase in the risk of neurodevelopmental disorders associated with buprenorphine compared to methadone, suggesting that buprenorphine may be a safer treatment option for opioid use disorder during pregnancy.

Effectiveness of interventions to increase vaccine uptake: component network meta-analysis

Apr 15, 2026

The authors aimed to identify effective components of interventions designed to increase vaccine uptake and to assess variations in effectiveness across different population groups, particularly in relation to the COVID-19 pandemic. Their component network meta-analysis of 237 studies revealed that strategies such as extended opportunities, appointment scheduling assistance, and motivational interviewing were effective, with the importance of human interaction and community involvement highlighted in delivery methods. The findings underscore the need for tailored interventions that consider age, underserved populations, and the context of the pandemic to enhance vaccine uptake.

Efficacy and safety of VPM1002 and Immuvac in preventing tuberculosis: phase 3 randomised clinical trial (PreVenTB trial)

Apr 10, 2026

The PreVenTB trial aimed to evaluate the safety and efficacy of the vaccines VPM1002 and Immuvac in preventing microbiologically confirmed tuberculosis (TB) among healthy household contacts of TB patients. The results indicated that while both vaccines were well tolerated, VPM1002 demonstrated significant efficacy against extrapulmonary TB, particularly in participants with a positive tuberculin skin test, but neither vaccine showed efficacy against all forms of confirmed TB or pulmonary TB. Overall, the study highlights the potential of VPM1002 in specific populations, despite limited effectiveness in broader TB prevention.

Non-drug perioperative interventions to reduce postoperative pulmonary complications after abdominal surgery: systematic review and meta-analysis

Apr 9, 2026

The authors aimed to evaluate the effectiveness of non-drug perioperative interventions in reducing postoperative pulmonary complications (PPCs) in adults undergoing abdominal surgery. Their systematic review and meta-analysis of 255 trials involving over 55,000 participants found that low fraction of inspired oxygen (FiO2) significantly reduced PPCs, while other interventions such as lung protective ventilation, physiotherapy, analgesia, and nutrition also showed moderate benefits. The study highlights the importance of prioritizing these effective strategies in clinical practice to enhance patient outcomes.

Airway management of adults in the acute care setting

Apr 8, 2026

The authors aim to provide an evidence-based approach to airway management for adults in acute care settings, addressing the challenges and complications associated with tracheal intubation. They emphasize the importance of preparation, appropriate drug selection, and the use of video laryngoscopy to enhance first-pass success, while also highlighting the need for effective analgesia and sedation to prevent awareness during procedures. The review consolidates current data and tools to improve airway management practices for clinicians.
