Analysis of foreign and Russian approaches to the study of personal patriotism
Authors: Cveks Mihails Vasil'evich 
Published: May 2024

The subject of the study is patriotism. The author conducted a theoretical analysis of domestic and foreign scientific literature on the problem of patriotism. The features of approaches to the study of this phenomenon in the framework of philosophical, sociological, historical, psychological, pedagogical and psychological disciplines are considered in detail. A comparative analysis of the theoretical views of foreign and domestic authors on the content and nature of patriotism is carried out. An analysis of the literature allows us to conclude that Western and Russian studies of patriotism have many connotations, especially in the sociological and political sciences. Western and domestic scientists have identified similar essential signs of patriotism: patriotism as one of the highest feelings, as a creative feeling; patriotism as selfless work for the benefit of one's country, as a manifestation of higher feelings in action, as a duty to the country; patriotism as a deeply social phenomenon, as a civic virtue. The author conducts a comparative theoretical analysis of foreign and domestic approaches to the study of the problem of patriotism, understanding the psychological nature of this phenomenon. The main conclusions of the study are: in the studies of foreign scientists, patriotism is analyzed in the context of national and social issues and is practically not studied as a personal education, property or quality; at the heart of patriotism, most foreign authors note identification with their country based on feelings of love, pride and shame. In the West, patriotism is seen as a phenomenon of political awareness, quite closely related to nationalism. In Russian literature, such essential signs of patriotism as statehood and personality, which is the main subject of patriotism, are noted. The differences in the interpretation of the concept of "patriotism" and in approaches to its research can be explained by fundamental differences in culture and state and political traditions. In turn, the intersections in the definition of patriotism indicate that this phenomenon has certain interethnic and interstate features. The question of studying remains open and quite relevant.

Objectives:
The primary objective was to compare the hypnotic efficacy of oral melatonin, oral L-theanine, and placebo in improving sleep in cancer patients with insomnia by the Athens Insomnia Scale (AIS). The secondary objective was to know the prevalence of insomnia in patients with cancer.

Materials and Methods:
A prospective, double-blinded, placebo-controlled study was conducted after obtaining Institutional Ethics Committee approval. One hundred and twenty patients were randomly assigned to either Group A (melatonin), Group B (L-theanine), or Group C (placebo). They were instructed to take the tablets for 14 consecutive days, two h (hours) before bedtime, and evaluated with AIS on the 1st day, 7th day, and 14th day.

Results:
There were seven dropouts: Two in Group A, two in Group B, and three in Group C. Significant differences in favour of melatonin treatment were found. There were statistically significant improvements in insomnia in cancer patients on melatonin intake compared to L-theanine. L-theanine had statistically significant improvements in insomnia in comparison to placebo. The mean ± standard deviation AIS on day one in Group A was 14.82 ± 1.29; on day seven was 10.92 ± 1.12; and on day 14 was 5.00 ± 0.70. Similarly, in Group B, the mean ± standard deviation AIS was 15.39 ± 1.03, 13.05 ± 1.06, and 9.55 ± 1.01, and in Group C, the mean AIS was 14.92 ± 1.40, 14.54 ± 1.35 and 13.05 ± 1.61 on the 1st, 7th and 10th day, respectively. There was an improvement in sleep from 1 to 7 days, 7 days to 14 days, and 1 day to 14 days in all the groups (P < 0.005).

Conclusion:
The hypnotic efficacy of oral melatonin 3 mg was better than oral L-theanine 200 mg in cancer patients having insomnia. Furthermore, L-theanine had a better hypnotic efficacy when compared to a placebo.

The floor plate is one of the important components in a multi-story building. Conventional methods are still widely used for building floor slabs. This method requires a lot of labor and time, which can reduce productivity. Other methods, such as bondek and half precast in floor slab work, are expected to increase work effectiveness and efficiency. This study aims to determine which method is most effective in floor slab work by reviewing cost, time, and work productivity. Floor plate planning consists of calculating each method's structural strength and volume of work, including formwork, reinforcement, concrete, and formwork dismantling. Cost analysis is carried out by collecting data on material prices and labor wages for the building's Draft Budget (RAB). Estimated work time involves formwork preparation, installation of reinforcement, and concrete casting for the three work methods. Based on the results of the calculation analysis on the floor slab work of the Al-Azhar Boys Dormitory Building with an area of the floor plate of 375,318 m2. Conventional floor slab work is more economical than bondek slab work by around 31.23%, but requires the longest work time. Meanwhile bondek floor slabs offer the fastest processing time, even though the cost is higher than conventional slabs, around 31.19% and 5.18% lower than half precast slabs. This can be a recommendation in choosing a floor slab work method.

Published: May 2024

OBJECTIVE
The mainstay of treatment for skull base chordoma (SBC) is maximal safe resection followed by radiotherapy. However, even after gross-total resection (GTR), the recurrence rate is high due to microscopic disease in the resection margins. Therefore, supramarginal resection (SMR) could be beneficial, as has been shown for sacral chordoma. The paradigm of postoperative radiation therapy for every patient has also begun to change, as molecular profiling has shown variability in the risk of recurrence. The aim of this study was to present the concept of SMR applied to SBC, along with an individualized decision for postoperative radiation therapy.

METHODS
This is a retrospective analysis of all SBCs operated on by the senior author between 2018 and 2023. SMR was defined as negative histological margins of bone and/or dura mater, along with evidence of bone resection beyond the tumor margins in the craniocaudal and lateral planes on postoperative imaging. Tumors were classified into 3 molecular recurrence risk groups (group A, low risk; group B, intermediate risk; and group C, high risk). Postoperative radiation therapy was indicated in group C tumors, in group B chordomas without SMR, or in cases of patient preference.

RESULTS
Twenty-two cases of SBC fulfilled the inclusion criteria. SMR was achieved in 12 (55%) cases, with a mean (range) amount of bone resection beyond the tumor margins of 10 (2–20) mm (+40%) in the craniocaudal axis and 6 (1–15) mm (+31%) in the lateral plane. GTR and near-total resection were each achieved in 5 (23%) cases. Three (19%) tumors were classified as group A, 12 (75%) as group B, and 1 (6%) as group C. Although nonsignificant due to the small sample size, the trends showed that patients in the SMR group had smaller tumor volumes (13.9 vs 19.6 cm3, p = 0.35), fewer previous treatments (33% vs 60% of patients, p = 0.39), and less use of postoperative radiotherapy (25% vs 60%, p = 0.19) compared to patients in the non-SMR group. There were no significant differences in postoperative CSF leak (0% vs 10%, p = 0.45), persistent cranial nerve palsy (8% vs 20%, p = 0.57), and tumor recurrence (8% vs 10%, p = 0.99; mean follow-up 15 months) rates between the SMR and non-SMR groups.

CONCLUSIONS
In select cases, SMR of SBC appears to be feasible and safe. Larger cohorts and longer follow-up evaluations are necessary to explore the benefit of SMR and individualized postoperative radiation therapy on progression-free survival.

OBJECTIVE
Postoperative thrombotic complications represent a unique challenge in cranial neurosurgery as primary treatment involves therapeutic anticoagulation. The decision to initiate therapy and its timing is nuanced, as surgeons must balance the risk of catastrophic intracranial hemorrhage (ICH). With limited existing evidence to guide management, current practice patterns are subjective and inconsistent. The authors assessed their experience with early therapeutic anticoagulation (≤ 7 days postoperatively) initiation for thrombotic complications in neurosurgical patients undergoing cranial surgery to better understand the risks of catastrophic ICH.

METHODS
Adult patients treated with early therapeutic anticoagulation following cranial surgery were considered. Anticoagulation indications were restricted to thrombotic or thromboembolic complications. Records were retrospectively reviewed for demographics, surgical details, and anticoagulation therapy start. The primary outcome was the incidence of catastrophic ICH, defined as ICH resulting in reoperation or death within 30 days of anticoagulation initiation. As a secondary outcome, post-anticoagulation cranial imaging was reviewed for new or worsening acute blood products. Fisher’s exact and Wilcoxon rank-sum tests were used to compare cohorts. Cumulative outcome analyses were performed for primary and secondary outcomes according to anticoagulation start time.

RESULTS
Seventy-one patients satisfied the inclusion criteria. Anticoagulation commenced on mean postoperative day (POD) 4.3 (SD 2.2). Catastrophic ICH was observed in 7 patients (9.9%) and was associated with earlier anticoagulation initiation (p = 0.02). Of patients with catastrophic ICH, 6 (85.7%) had intra-axial exploration during their index surgery. Patients with intra-axial exploration were more likely to experience a catastrophic ICH postoperatively compared to those with extra-axial exploration alone (OR 8.5, p = 0.04). Of the 58 patients with postoperative imaging, 15 (25.9%) experienced new or worsening blood products. Catastrophic ICH was 9 times more likely with anticoagulation initiation within 48 hours of surgery (OR 8.9, p = 0.01). The cumulative catastrophic ICH risk decreased with delay in initiation of anticoagulation, from 21.1% on POD 2 to 9.9% on POD 7. Concurrent antiplatelet medication was not associated with either outcome measure.

CONCLUSIONS
The incidence of catastrophic ICH was significantly increased when anticoagulation was initiated within 48 hours of cranial surgery. Patients undergoing intra-axial exploration during their index surgery were at higher risk of a catastrophic ICH.

OBJECTIVE
Use of bone morphogenetic protein (BMP)—an osteoinductive agent commonly used in lumbar arthrodesis—is off-label for cervical arthrodesis. This study aimed to identify the effect of BMP use on clinical and radiological outcomes in instrumented cervical arthrodesis.

METHODS
A comprehensive systematic review of the literature was performed to identify studies directly comparing outcomes between cervical arthrodeses with and without using BMP. Outcomes were analyzed separately for cases of anterior cervical discectomy and fusion (ACDF) and posterior cervical fusion (PCF).

RESULTS
A total of 20 studies with 5828 patients (1948 with BMP and 3880 without BMP) were included. In the ACDF cases, BMP use was associated with higher fusion rates (98.9% vs 93.6%, risk difference [RD] 8%; risk ratio [RR] 1.12, p = 0.02), lower reoperation rates (2.2% vs 3.1%, RD 3%; RR 0.48, p = 0.04), and higher risk of dysphagia (24.7% vs 8.1%, RD 11%; RR 1.93, p = 0.02). No significant differences in the Neck Disability Index, neck pain, or arm pain scores were associated with the use of BMP. On subgroup meta-analysis of ACDF cases, older age (≥ 50 years) and higher BMP dose (≥ 0.9 mg/level) were associated with significantly higher fusion rates and relatively lower risk for dysphagia, whereas arthrodesis of fewer segments (< 2 levels) showed significantly higher dysphagia rates without a significant increase in fusion rates. In the PCF cases, the use of BMP was not associated with significant differences in fusion (p = 0.38) or reoperation (p = 0.61) rates but was associated with significantly higher blood loss during surgery (mean difference 146.7 ml, p ≤ 0.01).

CONCLUSIONS
Use of BMP in ACDF offers higher rates of augmented fusion and lower rates of all-cause reoperation but with an increased risk of dysphagia. The benefit of fusion outweighs the risk of dysphagia with a higher BMP dose in older patients being operated on for < 2 levels. The use of BMP in PCF seems to have a less important effect on clinical and radiological outcomes.
