What the literature leaves open

  • The odds of spontaneous miscarriage, spontaneous fetal loss, elective cesarean section, 5-minute APGAR score <7, and admission to the neonatal intensive care unit were significantly greater in ASM-exposed than in unexposed pregnancies in women with the same indications, but the possible confounding effect of between-group differences in disease severity could not be assessed.

  • The mechanisms underlying VPA-associated weight gain remain incompletely mapped. There is a need for further research to fully understand the mechanisms of VPA-associated weight gain.

    Mechanisms of weight gain associated with valproic acid: a scoping review · 2026 · DOI

  • Our findings reveal well-established hormonal and lipid pathways alongside emerging but underexplored genetic mechanisms, highlight- ing key knowledge gaps that warrant further investigation. However, evidence remains inconclusive, and larger, standardized studies are needed to validate these associations, as current research often relies on small, heterogeneous cohorts (e. Findings on adiponec- tin were inconsistent, with some studies reporting reduced levels under VPA therapy, warranting further investigation.

    Mechanisms of weight gain associated with valproic acid: a scoping review · 2026 · DOI

  • Treatment resistance to antiepileptic medications. Unpleasant effects of antiepileptic medications. Lack of sufficient reliable pediatric clinical research on Valeriana wallichii.

  • There is a need for safer and more effective treatment options for preterm neonates with seizures. The current treatment options have limitations and potential adverse effects. There is a lack of randomized controlled trials comparing the effectiveness of different treatment options for preterm neonates with seizures.

    Levetiracetam Versus Phenobarbitone in the Treatment of Seizure in Preterm Neonate · 2026 · DOI

  • BACKGROUND AND OBJECTIVES: Evidence remains inconclusive on whether paternal valproate exposure during spermatogenesis is associated with adverse offspring outcomes, with findings lacking beyond Nordic countries.

    Monthly or menstrual? A scoping review of catamenial epilepsy and non‐menstrual seizure rhythms · 2026 · DOI

  • Lack of consensus on what entails a menstrual-related seizure exacerbation. Poorly defined diagnostic criteria for CE. Limited understanding of the relationship between seizure activity and the menstrual cycle.

  • Objective Sodium valproate (SV) is a widely used anti-epileptic drug with well-established reproductive and teratogenic effects, yet its impact on the developing prepubertal reproductive system remains poorly understood.

    Investigation into the effects of sodium valproate on prepubertal mouse gonads in vivo · 2026 · DOI

  • Nonetheless, the trend toward reduced testicular germ cell density warrants further investigation with longer exposure durations and functional fertility endpoints, to better inform clinical risk assessment in paediatric patients receiving SV.

  • The review was limited by the lack of access to certain documents due to legal reasons. Bayer asked the review not to publish or provide links to certain documents.

  • 72 process Ethicon agreed to pay Professor Ulmsten $400,000 if the early results that he had achieved with the TVT could be replicated by other surgeons. This consensus should be validated by carrying out follow up on those who have removals at the specialist centres. This consensus should be validated by carrying out follow up on those who have removals at the specialist centres. 462 A letter to its members from the British Association of Urological Surgeons (BAUS) in February 2004 recognised the lack of evidence and went on to say, ‘The European CE mark constitutes no more than recognition that the product is “fit for purpose” and it is possible for products to become registered with no clinical data at all. The outcome data that exists currently does not capture all reported symptoms, hence complication rates are not fully understood.

  • Atypical neuroleptic malignant syndrome is a difficult matter, especially when symptoms of hyperthermia or muscle rigidity is lacking, but using Levenson's or Adityanjee and Aderibigbe's criteria may increase it detectability, can permit earlier intervention and prevent development of life-threatening typical neuroleptic malignant syndrome.

  • TDM has been used as a tool to optimize treatment of epilepsy for almost 50 years, and while VPA evidence for its usefulness in improving clinical outcome is scarce, TDM continues to play a role in epilepsy management for reasons: (1) physiological changes due to aging, pregnancy, nutritional status, drug interactions, and comorbidities (ie, those involving…
