Published: May 2024

OBJECTIVE

The authors of this study aimed to investigate independent prognostic factors of survival with a particular focus on comparing the safety and efficacy of endoscopic endonasal versus open approaches in the surgical management of skull base chordoma.

METHODS

A retrospective National Cancer Database review of skull base chordoma patients was performed to capture resection cases from 2010 to 2020, evaluating overall survival (OS), early postoperative mortality, readmission rates, and hospital length of stay (LOS) between surgical approaches and the independent prognostication of death utilizing Cox multivariate regression analysis.

RESULTS

Among the 736 patients included in the cohort, 456 patients (62.0%) and 280 patients (38.0%) underwent endoscopic endonasal and open resection, respectively. These values represent a rate of change over the study period of +4.1 versus –0.14 cases per year, respectively. Gross-total resection was achieved in 32.5% of cases. A positive margin status was found in 51.8% of cases. There was no association between extent of resection and surgical approach (p = 0.257). There was no difference in OS (p = 0.562), 30- and 90-day mortality (p = 0.209 and 0.126, respectively), and 30-day readmission (p = 0.438) between the two surgical groups. The mean LOS was reduced by 2.1 days in the endoscopic cohort (p = 0.013) compared with the open approach cohort. Finally, multivariate analysis revealed a tumor size ≥ 4 cm (HR 4.03, p = 0.005) and public insurance (HR 2.76, p = 0.004) as negative predictors of survival and treatment at an academic center (HR 0.36, p = 0.043) as a positive prognosticator of survival.

CONCLUSIONS

The endoscopic endonasal approach has been increasingly utilized over time and touts noninferiority with respect to safety and efficacy with a marked improvement in LOS, which carries substantial implications for both healthcare costs and enhanced patient recovery. Future prospective studies are necessary to further delineate trends and surgical outcomes for skull base chordoma.

OBJECTIVE

Chordomas are locally aggressive neoplasms of the spine or skull base that arise from embryonic remnants of the notochord. Intradural chordomas represent a rare subset of these neoplasms, and few studies have described intradural chordomas in the spine. This review evaluates the presentation, management, and outcomes of intradural spinal chordomas.

METHODS

A systematic review of PubMed/MEDLINE, EMBASE, Cochrane Library, Scopus, and Web of Science was performed. Studies describing at least 1 case of intradural chordomas anywhere in the spine were included. Extracted details included presenting symptoms, radiological findings, treatment course, follow-up, and disease progression.

RESULTS

Thirty-one studies, with a total of 41 patients, were included in this review. Seventy-six percent (31/41) of patients had primary intradural tumors, whereas 24% (10/41) presented with metastasis. The most common signs and symptoms were pain (n = 27, 66%); motor deficits (n = 20, 49%); sensory deficits (n = 17, 42%); and gait disturbance (n = 10, 24%). The most common treatment for intradural chordoma was resection and postoperative radiotherapy. Sixty-six percent (19/29) of patients reported improvement or complete resolution of symptoms after surgery. The recurrence rate was 37% (10/27), and the complication rate was 25% (6/24). The median progression-free survival was 24 months (range 4–72 months). Four patient deaths were reported. The median follow-up time was 12 months (range 13 days–84 months).

CONCLUSIONS

Treatment of intradural spinal chordomas primarily involves resection and radiotherapy. A significant challenge and complication in management is spinal tumor seeding after resection, with 9 studies proposing seeding as a mechanism of tumor metastasis in 11 cases. Factors such as tumor size, Ki-67 positivity, and distant metastasis may correlate with worse outcomes and demonstrate potential as prognostic indicators for intradural spinal chordomas. Further research is needed to improve understanding of this tumor and develop optimal treatment paradigms for these patients.

Published: May 2024

OBJECTIVE

There is a lack of effective drugs to treat the progression and recurrence of chordoma, which is widely resistant to treatment in chemotherapy. The authors investigated the functional and therapeutic relevance of the E1A-binding protein p300 (EP300) in chordoma.

METHODS

The expression of EP300 and vimentin was examined in specimens from 9 patients with primary and recurrent chordoma with immunohistochemistry. The biological functions of EP300 were evaluated with Cell Counting Kit-8, clonogenic assays, and transwell assays. The effects of EP300 inhibitors (C646 and SGC-CBP30) on chordoma cell motility were assessed with these assays. The effect of the combination of EP300 inhibitors and cisplatin on chordoma cells was evaluated with clonogenic assays. Reverse transcription quantitative polymerase chain reaction and Western blot techniques were used to explore the potential mechanism of EP300 through upregulation of the expression of vimentin to promote the progression of chordoma.

RESULTS

Immunohistochemistry analysis revealed a positive correlation between elevated EP300 expression levels and recurrence. The upregulation of EP300 stimulated the growth of and increased the migratory and invasive capabilities of chordoma cells, along with upregulating vimentin expression and consequently impacting their invasive properties. Conversely, EP300 inhibitors decreased cell proliferation and downregulated vimentin. Furthermore, the combination of EP300 inhibition and cisplatin exhibited an enhanced anticancer effect on chordoma cells, indicating that EP300 may influence chordoma sensitivity to chemotherapy.

CONCLUSIONS

These findings indicate that EP300 functions as an oncogene in chordoma. Targeting EP300 offers a novel approach to the development and clinical treatment of chordoma.

Published: May 2024

OBJECTIVE

The influence of sleep on baseline and postconcussion neurocognitive performance prior to Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is poorly understood. Since ImPACT is widely used in youth sport to assess neurocognitive performance before and after head injury, it is important to delineate factors that affect testing performance. While some have reported correlations between fewer hours of sleep and lower scores on baseline tests, others have not observed any such associations. Therefore, the authors sought to compare the relationship between sleep and neurocognitive performance on ImPACT at both baseline and postinjury.

METHODS

The authors queried a database of 25,815 ImPACT tests taken from 2009 to 2019 by athletes aged 12–22 years. There were 11,564 baseline concussion tests and 7446 postinjury concussion ImPACT tests used in the analysis. Linear regression was used to model the effect of sleep on baseline and postconcussion ImPACT scores adjusting for sex, age, learning disability, attention-deficit/hyperactivity disorder, number of prior concussions, number of games missed, and strenuous exercise before testing.

RESULTS

Mean composite scores expectedly were all significantly lower in the post–head injury group compared with the baseline group. In the multivariable analysis, at baseline, hours of sleep significantly affected symptom scores (β = −1.050, 95% CI −1.187 to −0.9138; p < 0.0001). In the postinjury multivariable analysis, verbal memory (β = 0.4595, 95% CI 0.2080–0.7110; p = 0.0003), visual memory (β = 0.3111, 95% CI 0.04463–0.5777; p = 0.0221), impulse control (β = −0.2321, 95% CI −0.3581 to −0.1062; p = 0.0003), and symptom scores (β = −0.9168, 95% CI −1.259 to −0.5750; p < 0.0001) were all affected by hours of sleep.

CONCLUSIONS

Hours of sleep did not alter neurocognitive metrics at baseline but did have an impact on post–head injury metrics. These findings suggest that individuals may be able to compensate for lack of sleep at baseline but not immediately after concussion. Concussions may reduce cognitive reserve or detract from the brain’s resources, making sleep even more important for proper neurocognitive functioning postconcussion. Future work will analyze the effects of sleep on postconcussion test performance.
Development of moyamoya arteriopathy following treatment of intracranial tumors: clinical and radiographic characterization
Authors: Lee Jong Seok , Storey Armide , Lanpher Arianna , Smith Edward R.
Published: May 2024

OBJECTIVE

Moyamoya arteriopathy can develop in patients with brain tumors, particularly when associated with neurofibromatosis type 1 (NF1) or cranial irradiation. The present study aimed to analyze the clinical outcomes of moyamoya after brain tumor treatment and elucidate the effect of revascularization on brain tumors.

METHODS

The authors retrospectively reviewed clinical and radiographic findings in 27 patients with brain tumors who developed moyamoya requiring revascularization surgery between January 1985 and June 2017 at a single institution. The long-term clinical and neuroimaging-based outcomes were analyzed.

RESULTS

Among 27 patients, 22 patients underwent radiotherapy, and 12 patients had NF1. The mean ages at diagnosis of brain tumors and moyamoya were 4.4 years and 10.3 years, respectively. The mean interval between radiotherapy and moyamoya diagnosis was 4.0 years. The mean follow-up period after revascularization surgery was 8.5 years. Among 46 affected hemispheres in 27 patients, the patients who underwent radiotherapy (30 hemispheres in 22 patients) had a higher incidence of Suzuki stage 5 or 6 (20% [6/30] vs 0% [0/8]) and infarction (63.6% [14/22] vs 0% [0/5]) compared with patients without radiotherapy (8 hemispheres in 5 patients). After revascularization, stroke occurred in 4 patients, and 6 hemispheres showed Matsushima grade C, all of which occurred in patients with a history of radiotherapy. The residual brain tumors progressed in 4 of 21 patients (19%) after revascularization, comparable to the progression rates of brain tumors without revascularization in previous literature.

CONCLUSIONS

Patients with brain tumors can develop moyamoya that exhibits characteristic clinical and radiographic features of idiopathic MMD. Moyamoya associated with cranial irradiation has a higher incidence of stroke with less capacity for revascularization, requiring thorough evaluations and timely treatment. Revascularization does not appear to have any effect on the progression of existing brain tumors.

Published: May 2024

An analysis of the silica nanosol-hexadecyltrimethoxysilane hybrid has been carried out through optimizing the concentration of silica nanosol and determining the type of fabric regarding hydrophobicity. This research began with the synthesis of silica nanosol via the sol-gel method, where TEOS as a precursor was dissolved in a mixture of ethanol-distilled water with a base catalyst with a contact time of 2 hours. The concentration of silica nanosol was varied by 0.025, 0.05, and 0.075 mol. The dip-coating method was used to coat the fabric with nanosol, with a tensile rate of 3 cm per second. Then the fabric was re-coated with silica nanosol in HDTMS solution (4% wt/wt ethanol) and dried in a 120°C oven for 10 minutes. This research tested calico, cotton and mori fabrics. A Canon DSLR camera with a Thamron 100mm lens was used to measure the contact angle of the fabric surface. ImageJ software processes images to obtain contact angle values on the fabric surface. The fabric was then characterized using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscope (SEM) and the silica nanosol was characterized using a Transmission Electron Microscope (TEM). The optimum concentration of silica-hdtms nanosol was obtained at a concentration of 0.075 mol with surface contact angles of cotton, mori and calico fabrics of 134, 132 and 135°. The flow speed of water with a slope of 100 on cotton, mori, and calico fabric produces flow speeds of 3.3, 6, and 5 m/s.
The use of dexmedetomidine in suppressing cardiovascular response due to intubation in general anesthesia
Authors: Zulfikar Zulfikar
Published: May 2024

Endotracheal intubation is commonly used to maintain a safe airway during general anesthesia. This intubation action can trigger a dangerous response for the patient, one of which is the cardiovascular system. Increases in arterial blood pressure, plasma catecholamine levels, and heart rate are responses that can occur during intubation. Therefore, various methods and treatments have been used to control this cardiovascular response, including dexmedetomidine. Dexmedetomidine is a highly selective α2-adrenergic receptor agonist that has analgesic, sympatholytic, and sedative effects with minimal depression of ventilation. Much research has been done on how well dexmedetomidine works to stop the cardiovascular response to intubation. Dexmedetomidine was significantly associated with reductions in heart rate, systolic blood pressure, and MAP.

IMPLEMENTASI BIODIESEL HVO DI INDONESIA : METODE ECONOMIC BENEFIT COST ANALYSIS
Authors: Imaniar Rizani
Published: May 2024

Dalam forum United Nation Framework Convention on Climate Change (UNFCCC) – Conference of Parties (COP) ke-21 pada Desember 2015, Presiden Republik Indonesia menyampaikan komitmen nasional terkait penurunan emisi gas rumah kaca (GRK) salah satunya melalui pengembangan energi terbarukan. Komitmen nasional ini ditindaklanjuti dengan pengembangan roadmap energi nasional yang dikenal dengan Grand Strategi Energi Nasional (GSEN) oleh Dewan Energi Nasional (DEN) dimana Indonesia memiliki target Nationally Determined Contributions (NDC) sebesar 314 juta ton CO2e per tahun penurunan emisi karbon dari sektor energi yang harus dicapai pada tahun 2030 (hingga 2020 telah tercapai 64,4 juta ton CO2e per tahun).
Salah satu upaya yang dilakukan terkait pengembangan energy terbarukan adalah dengan implementasi biodiesel yang sejak tahun 2019 telah mulai diimplementasikan dengan pencampuran bahan bakar diesel dengan Fatty Acid Methyl Ester (FAME) yang saat ini dikenal dengan B30 (blending 30% bahan bakar nabati dengan 70% bahan bakar diesel). Namun Secara teknis B30 dengan blending FAME tidak bisa melebihi 30% karena keterbatasan teknis (water content, monoglyceride, dll). Sedangkan Presiden Republik Indonesia memiliki target yang cukup ambisius yaitu tingkat blending yang lebih tinggi yaitu B40 bahkan hingga B50. Untuk itu, Hydrotreated Vegetable Oil (HVO) muncul sebagai solusi yang dapat memenuhi dari sisi kriteria teknis. Namun terdapat beberapa pertimbangan dari sisi keekonomian nya.
Setelah penelitian ini mengukur kelayakan dari sisi finansial proyek, serta mempertimbangkan pula beberapa aspek benefit lain yang muncul antara lain seperti kontribusi terhadap target pencapaian NDC sebesar 521,000 ton reduksi CO2e per tahun, penghematan current account deficit dan lain sebagainya maka proyek ini layak dari sisi Economic Benefit Cost Analysis.

Published: May 2024

В работе изучен уровень экологической культуры и мировоззрения среди различных социальных групп в г. Астана. Проведен социальный опрос среди обучающихся и преподавателей ВУЗов, учеников школ, г. Астаны, специалистов департамента экологии по г. Астана, предприятий-природопользователей, а также волонтеров и граждан столицы. Статья рассматривает факторы, влияющие на уровень экологической грамотности, а также ответственность населения в области охраны окружающей среды. Проведенный онлайн опрос выявил относительно удовлетворительный уровень экологической культуры населения города, однако имеется недостаточность экологичного поведения населения в секторе обращения с твердо-бытовыми отходами.  Анализ результатов опроса по возрастным и отраслевым категориям, а также полученные предложения специалистов и граждан столицы позволяют корректировать образовательные программы и воспитательные мероприятия по повышению общей экологической образованности и культуры.

Authors: Itan Iskandar , Giovani Marshella , Butar-Butar Dea Tiara Monalisa
Published: May 2024

This research seeks to explore how the implementation of social responsibility practices impacts a company's performance and to investigate whether certain characteristics of the board play a moderating role in this relationship. The study collected data from 43 companies listed on the Indonesia Stock Exchange (IDX) that engaged in social responsibility activities during the period from 2017 to 2022. The analysis employed panel regression techniques. The findings of the study indicate a noteworthy negative correlation between corporate social responsibility (CSR) and return on assets (ROA). Conversely, the relationship between CSR and Tobin's Q is found to be statistically insignificant and positive. Moreover, the number of directors does not appear to moderate the relationship between CSR and company performance, whether measured by ROA or Tobin's Q. Similarly, independent commissioners do not seem to moderate the relationship between CSR and company performance when measured by ROA, but they do exhibit a moderating effect in the context of Tobin's Q.
