This article delves into the dynamics of human interaction with artificial intelligence (AI), emphasizing the optimization of these interactions to enhance human productivity. Employing a Grounded Theory Literature Review (GTLR) methodology, the study systematically identifies and analyzes themes from literature published between 2018 and 2023. Data were collected primarily from the Scopus database, with the Web of Science used to corroborate findings and include additional sources identified through a snowball effect.

We introduce FocalPose++, a neural render-and-compare method for jointly estimating the camera-object 6D pose and camera focal length given a single RGB input image depicting a known object. The contributions of this work are threefold. First, we derive a focal length update rule that extends an existing state-of-the-art render-and-compare 6D pose estimator to address the joint estimation task.

Background: Glioblastoma (GB) is the most common intrinsic brain cancer and is notorious for its aggressive nature. Despite widespread research and optimization of clinical management, the improvement in overall survival has been limited. The aim of this study was to characterize the impact of service reconfiguration on GB outcomes in a single centre.

Objective: To determine how the first wave of the COVID-19 pandemic affected outcomes for all operatively managed neurosurgical patients, not only those positive for SARS-CoV-2.

Design: Matched cohort (pairwise method).

Setting: A single tertiary neurosurgical referral centre at a large UK Major Trauma Centre.

Article Synopsis
  • MRI is crucial for evaluating brain lesions, but conventional MRI lacks specificity.
  • Multiparametric MRI, which includes advanced techniques like diffusion and perfusion-weighted imaging, offers better insights into tissue conditions.
  • This review aims to illustrate the effectiveness of multiparametric MRI in diagnosing and planning treatment, showcasing cases that highlight its superior ability to distinguish between cancerous and non-cancerous lesions compared to standard MRI.

Spontaneous spinal epidural haematoma is a rare entity associated with high morbidity. Although there are previous reports of spinal haematoma secondary to X-linked genetic haemophilia, there are no such cases secondary to acquired autoimmune haemophilia. We report the case of a 71-year-old patient who presented with sudden quadriplegia secondary to cervical (C2 to T1) epidural haematoma as a result of undiagnosed autoimmune acquired haemophilia A.

Background: Artificial cervical disk replacements are commonly used to treat radiculomyelopathy caused by degenerative disk disease. However, long-term disk mobility and an effect on adjacent segment disease have yet to be demonstrated. We report improvements in clinical outcome after disk replacement but also demonstrate potential limitations.

Angiogenesis plays a key role in glioblastoma biology and antiangiogenic agents are under clinical investigation with promising results. However, the angiogenic profiles of patients with glioblastoma and their clinical significance are not well understood. Here we characterize the serum angiogenic profile of patients with glioblastoma, and examine the prognostic significance of individual angiogenic factors.

Background: Glioblastoma, the most common primary brain tumor, has variable prognosis. We aimed to identify serum biomarkers that predict survival of patients with glioblastoma.

Methods: In phase 1 (biomarker discovery), SELDI-TOF mass spectra were studied in 200 serum samples from 58 control subjects and 36 patients with grade II astrocytoma, 15 with anaplastic astrocytoma, and 91 with glioblastoma.

Currently, brain tumours are diagnosed by surgical biopsy and light microscopic examination of tissue, with immunohistochemistry in difficult cases. We review research in the field of brain tumour diagnosis and discuss several new approaches. In future, tumour type, optimal treatment, and prognosis could be obtained by studying the gene (genomics), protein (proteomics) or metabolite (metabolomics) content of tumour cells.

Objective: To provide a historical account of the events surrounding the development of the computed tomography scanner.

Methods: Information was obtained by interviewing people who worked with Sir Godfrey Hounsfield and Dr. James Ambrose at Atkinson Morley's Hospital in the 1970s, and from published books, articles, and several web sites, including the Nobel web site.
