Summary: The objective of this study was to assess the 5-year h-index (h5-index) by nation and examine its relationship with the numbers of neurosurgeons, population, gross domestic product (GDP), and expenditure on health and research. The results showed a strong positive correlation between the h5-index and GDP, proportion of GDP spent on health, and total amount spent on health per capita. In terms of the total number of publications, a strong positive correlation was found with GDP and the total number of neurosurgeons. In conclusion, GDP and health expenditure were found to be the strongest correlates of the h5-index, and a higher number of neurosurgeons did not necessarily result in higher quality research.

Summary: This study re-evaluated the h-index of neurosurgical units in the UK and Ireland, showing changes in rankings over a 5-year period. The h-index is deemed the most reliable bibliometric, correlating with academic standing and research activity. Regular updates of ranking tables and the establishment of an online database for transparency and accessibility are recommended.

Summary: This study evaluated the influence of multiple author profiles on neurosurgeons' academic productivity metrics (h-index, document number, citation number) on Scopus. It found that having multiple profiles leads to a 17.3% decrease in h-index, a 16.2% decrease in document number, and a 14.1% decrease in citation number.

Summary: The academic productivity of neurosurgeons with international medical school and residency training did not significantly differ from those trained in the United States. However, dual fellowship training in both domestic and international programs was associated with higher academic productivity.

Summary: Author-level bibliometrics can be used to measure scholarly contributions, and Google Scholar provides a more comprehensive reflection of the contributions of special education scholars. This study analyzed publicly available Google Scholar profiles of special education faculty at 213 U.S. universities and explored current measures such as citation counts, h-index, and i10-index. The findings showed significant differences across variables based on academic rank and Carnegie classification. The currently reported metrics favored scholars with higher academic rank and those working at universities with higher research activity. Suggestions are provided for career development.

Summary: A new bibliometric indicator called the citing authors index was proposed to assess the impact and spread of individual scientific research by focusing on the number of citing authors. The index was tested in the mathematical community using the MathSciNet database and an aggregate version was also proposed for comparing different institutions' performances.

Summary: While the decline in the number of publications in UK anaesthesia has flattened, the output remains at half the level of the 1990s when considering a wider range of publication types. The majority of papers are in secondary analysis research, reflecting the current academic capacity in terms of publications, academic units, and staffing. This information can be used to inform a new strategy for UK academic anaesthesia.

Summary: The William P. Van Wagenen Fellowship has provided opportunities for young neurosurgeons to pursue research outside their country of residency, with a high return on investment in terms of academic productivity. The majority of fellows have remained in academic neurosurgery, with many receiving NIH funding and achieving professorships. The fellowship has also produced leaders in neurosurgery who have contributed back to the field through research funding.

Summary: The sudden spread of the monkeypox virus has led to increased scientific interest, with over 1,400 PubMed-indexed documents authored by about 5,800 unique authors. More than 30% of the documents are Quantitative Productivity (QP), illustrating emerging trends. There are also hyper-prolific authors previously identified in the COVID-19 literature, indicating continued interest in publishing monkeypox literature.

Summary: Despite recent advances in depression treatment, many patients still do not respond to serial conventional therapies and are considered treatment resistant. Deep brain stimulation (DBS) has therapeutic potential in this context. This comprehensive review of recent studies of DBS for depression in animal models identifies potential biomarkers for improving therapeutic efficacy and predictability of conventional DBS to aid future development of closed-loop control of DBS system.

Summary: Although dopamine is the most implicated neurotransmitter in addiction, serotonin also plays a vital role. This study used N-shaped fast-scan cyclic voltammetry to investigate the acute effects of cocaine on phasic serotonin release in the nucleus accumbens core. The findings contribute to our understanding of the mechanism of action of cocaine and provide a baseline for further research in cocaine addiction.

Summary: This review summarizes the preclinical and clinical studies of deep brain stimulation (DBS) as a novel therapy for refractory addiction. Animal studies showed that DBS reduces drug use and seeking, while human studies targeting the nucleus accumbens (NAc) had positive outcomes. Future research should explore the use of objective biomarkers and investigate DBS in other brain regions.

Summary: This article presents a case of trigeminal CCM in a child with otalgia and left-sided headaches. The patient initially underwent radiological surveillance but eventually required microsurgical resection. The study concludes that a CCM should be considered in the differential diagnosis of mass lesions in the trigeminal nerve area, and surgical resection is recommended to prevent neurological deterioration.

Summary: DBS as a treatment for substance use disorder (SUD) is being explored due to the limitations of current treatment modalities. Ethical concerns include informed consent and risks/benefits of DBS compared to traditional methods. Legal issues may arise from the criminalization of substance use and familial consent. Given the lack of clinical guidelines, general medico-legal principles should be considered for responsible use of DBS, and incorporating the IDEAL framework is recommended for future research.

Summary: Deep brain stimulation (DBS) is effective for treating neurological diseases, but implanting the device can cause cosmetic concerns. This study presents a subfascial technique for implanting the IPG under the breast to improve aesthetics. An inframammary incision provides better cosmetic outcomes and reduces complications compared to other implantation planes.

Summary: This study investigated the outcomes of postoperative discitis treated with debridement and a novel technique focused on reducing outpatient antibiotic requirement in a low- and middle-income country (LMIC) setting. The results showed that patients with medically refractory postoperative discitis potentially have good outcomes after debridement plus 2-week local antibiotic instillation in LMICs.

Summary: Corticocortical evoked potentials (CCEPs) have emerged as a valuable intraoperative monitoring technique in eloquent brain tumor surgery, aiding in preserving critical functional areas. Current research shows the potential of CCEPs in guiding surgical decision making, reducing the risk of postoperative neurological deficits, and mapping functional connectivity, but further research and standardization are needed.

Summary: This study aimed to compare the effect of different Modic changes (MC) grades on the cage subsidence rate after spinal interbody fusion surgery. A meta-analysis was conducted on relevant randomized controlled trials and cohort studies. The results showed that MC may be associated with a higher cage subsidence rate. With the increase in MC grades, the incidence of subsidence decreased gradually, but it was always higher than that in the non-Modic changes (NMC). Oblique lumbar interbody fusion may be a better treatment choice for lumbar degenerative disease with MC.

Summary: Early exposure to neurosurgery during medical school is critical for improving recruitment into the specialty. However, about 30% of medical schools in the U.S. lack a neurosurgery program, limiting students' exposure to the field. Virtual education, facilitated by webinars during the pandemic, has advantages such as global outreach and accessibility for international medical students. This review identifies and describes 16 educational resources, serving as a guide for medical students interested in neurosurgery.
