Introduction: Microsurgery for paraclinoid aneurysms remains the first line of treatment in resource-constrained settings. The authors describe their institutional experience and evaluate functional outcomes after microsurgical treatment of paraclinoid aneurysms.
Methods: A retrospective review of clinical records was conducted.
Objectives: The specific aims of the project are: (1) Examine the impact of COVID-19 on pregnancy experiences and outcomes; (2) Examine the mental health impact of COVID-19 in pregnant women and mothers of children 12 months or younger; (3) Identify risk and protective factors among this population in Puerto Rico.
Methods: Participants were recruited from the Puerto Rico Team for Exploring Contamination Threats (PROTECT) Superfund Program, which is composed of pregnant women and mothers from the northern karst region of Puerto Rico. The research had a mixed methods approach with a quantitative survey (n = 184) and qualitative interviews (n = 10); data collection was done in virtual mode.
Article Synopsis
- Cancers of unknown primary (CUP) are aggressive cancers where the origin remains unidentified, making treatment difficult and leading to poor outcomes.
- Advances in large-scale sequencing and machine learning have opened up new pathways for diagnosing CUP by identifying specific genetic signatures, even from blood samples.
- The review discusses the strengths and weaknesses of machine learning in classifying CUP tumors, emphasizing the need for improved strategies that integrate diverse data types to enhance diagnostic accuracy in clinical settings.
Although endovascular management has been increasingly adopted for basilar apex aneurysms (BAAs), microsurgery still represents an amenable treatment option. In this case series, six female patients (median age: 46 years) with six saccular high-riding BAAs (50% ruptured) were included. The median neck size was 5.

- Posterior communicating artery (PCoA) aneurysms account for about 15-25% of intracranial aneurysms and come with a 44% rupture risk, complicating surgical procedures due to limited visibility.
- A case is presented involving a 54-year-old woman who experienced severe headaches, vomiting, and a loss of consciousness, leading to a diagnosis of a PCoA aneurysm via imaging after a subarachnoid hemorrhage.
- She successfully underwent a right minipterional craniotomy with exoscopic clipping, which provided high-quality images and improved ergonomics during surgery, resulting in her significant recovery within three days post-operation.
