Abstract: Disasters threaten the safety of vulnerable groups such the eldery, children and women. Based on the case of natural disasters that occurred in Indonesia, the need for a pragmatic strategy in forming the Indonesian people are aware of the dangers of natural disasters. One strategic step that taken is through the education sector. This research aims to create a disaster mitigation curriculum that has been formulated to produce disaster responsive learners. This research uses R&D (research and development method) by Borg and Gall (2003), in the stages of research and information, planning and initial product development. While for curriculum development used the Tyler model with the infusion method and block method. Data collection techniques used namely interviews, observation, and documentation. The findings of this research are based curriculum products to the stages of disaster mitigation include, 1) the concept of disaster mitigation curriculum, 2) The concept of the learning process (Intrakurikuler), 3) The concept of training process (Extracurricular, and 4) The concept of the assessment process (Evaluation). These results indicate curriculum products are made to increase disaster response capabilities of students through intracurricular and extracurricular activities as well as minimizing the impact of the disaster victims and improve disaster response capabilities for students in Indonesia.

Postoperative outcomes and the association with overlap before or after the critical step of lumbar fusion
Authors: Farooqi Ali S. , Borja Austin J. , Detchou Donald K. E. , Glauser Gregory , Shultz Kaitlyn , McClintock Scott D. , Malhotra Neil R. 
Published: October 2021

OBJECTIVE
This study assesses how degree of overlap, either before or after the critical operative portion, affects lumbar fusion outcomes.

METHODS
The authors retrospectively studied 3799 consecutive patients undergoing single-level, posterior-only lumbar fusion over 6 years (2013–2019) at a university health system. Outcomes recorded within 30–90 and 0–90 postoperative days included emergency department (ED) visit, readmission, reoperation, overall morbidity, and mortality. Furthermore, morbidity and mortality were recorded for the duration of follow-up. The amount of overlap that occurred before or after the critical portion of surgery was calculated as a percentage of total beginning or end operative time. Subsequent to initial whole-population analysis, coarsened exact-matched cohorts of patients were created with the least and most amounts of either beginning or end overlap. Univariate analysis was performed on both beginning and end overlap exact-matched cohorts, with significance set at p < 0.05.

RESULTS
Equivalent outcomes were observed when comparing exact-matched patients. Among the whole population, the degree of beginning overlap was correlated with reduced ED visits within 30–90 and 0–90 days (p = 0.007, p = 0.009; respectively), and less 0–90 day morbidity (p = 0.037). Degree of end overlap was correlated with fewer 30–90 day ED visits (p = 0.015). When comparing only patients with overlap, degree of beginning overlap was correlated with fewer 0–90 day reoperations (p = 0.022), and no outcomes were correlated with degree of end overlap.

CONCLUSIONS
The degree of overlap before or after the critical step of surgery does not lead to worse outcomes after lumbar fusion.
Novel wrapping surgery for symptomatic sacral perineural cysts
Authors: Sugawara Taku , Higashiyama Naoki , Tamura Shinya , Endo Takuro , Shimizu Hiroaki 
Published: October 2021

OBJECTIVE
Perineural cysts, also called Tarlov cysts, are dilatations of the nerve root sleeves commonly found in the sacrum. The majority of the cysts are asymptomatic and found incidentally on routine spine imaging. Symptomatic sacral perineural cysts (SPCs) that induce intractable low-back pain, radicular symptoms, and bladder/bowel dysfunction require surgery. However, the surgical strategy for symptomatic SPCs remains controversial. The authors hypothesized that the symptoms were caused by an irritation of the adjacent nerve roots caused by SPCs, and developed a wrapping surgery to treat these cysts.

METHODS
Seven patients with severe unilateral medial thigh pain and ipsilateral SPCs were included. Preoperative MRI showed that the cysts were severely compressing the adjacent nerve roots in all patients. After a partial laminectomy of the sacrum, the SPCs were punctured and CSF was aspirated to reduce their size, followed by dissection of the adjacent nerve roots from the SPCs. The SPCs were then wrapped with a Gore-Tex membrane to avoid reexpansion.

RESULTS
All 7 patients experienced substantial relief of their symptoms. The average numeric rating scale pain score was reduced from an average preoperative value of 7.9 to 0.6 postoperatively. Postoperative MRI showed that all cysts were reduced in size and the adjacent nerve roots were decompressed. Regrowth of the treated cysts or recurrence of the symptoms did not occur during the entire follow-up period, which ranged from 39 to 90 months. No complications were noted.

CONCLUSIONS
The authors’ new wrapping technique was effective in relieving radicular symptoms for patients with symptomatic SPCs. The results suggested that the symptoms stemmed from compression of the adjacent nerve roots caused by the SPCs, and not from the nerve roots in the cysts.
Failure patterns and related risk factors of sagittal reconstruction following pedicle subtraction osteotomy in patients with ankylosing spondylitis and thoracolumbar kyphosis

Published: October 2021

OBJECTIVE
The aim of this study was to analyze the specific patterns and risk factors of sagittal reconstruction failure in ankylosing spondylitis (AS)–related thoracolumbar kyphosis after pedicle subtraction osteotomy (PSO).

METHODS
A retrospective study was performed in patients with AS and thoracolumbar kyphosis after lumbar PSO with a minimum follow-up of 2 years. Patients were classified as having successful realignment (group A), inadequate correction immediately postoperatively (group B), and sagittal decompensation during follow-up (group C) according to the immediately postoperative and latest follow-up sagittal vertical axis (SVA). Radiographic parameters and clinical outcomes were collected. Pelvic tilt (PT) was used to assess the magnitude of pelvic backward rotation. Hip structural damage and ossification of the anterior longitudinal ligament (ALL) at the proximal junction, PSO level, and distal junction were also evaluated on radiographs.

RESULTS
Overall, 109 patients with a mean age of 35.3 years were included. Patients in both group B (n = 16) and group C (n = 13) were older than those in group A (n = 80) (mean ages 43.6 vs 32.9 years, p < 0.011; and 39.2 vs 32.9 years, p = 0.018; respectively). Age (OR 1.102, p = 0.011), and preoperative PT (OR 1.171, p = 0.041) and SVA (OR 1.041, p = 0.016) were identified as independent risk factors of inadequate correction. Additionally, a higher distribution of patients with adequate ALL ossification at the PSO level was found in group B than in group A (37.5% vs 22.5%, p = 0.003). Age (OR 1.101, p = 0.011) and preoperative SVA (OR 1.013, p = 0.020) were identified as independent risk factors of sagittal decompensation. Furthermore, compared with group A, group C showed a higher distribution of patients with severe hip structural damage (15.4% vs 0, p = 0.018) and higher incidences of rod fracture (RF) (38.5% vs 8.8%, p = 0.011) and pseudarthrosis (15.4% vs 0, p = 0.018). Additionally, the incidence of RF (19.6% vs 6.9%, p = 0.045) and changes in the proximal junctional angle (0.5° vs 2.2°, p = 0.027) and the distal junctional angle (0.3° vs 2.2°, p = 0.019) were lower during follow-up in patients with adequate ALL ossification than in those without adequate ossification.

CONCLUSIONS
Sagittal reconstruction failure in patients with AS could be attributed to inadequate correction immediately after surgery (14.7%) and sagittal decompensation during follow-up (11.9%). Adequate ALL ossification was a risk factor of inadequate correction. However, adequate ALL ossification could decrease the development of RF and relieve the junctional kyphotic change during follow-up. Older age and greater baseline SVA were independent risk factors for both inadequate correction and sagittal decompensation.
The role of an anterior approach in the treatment of ankylosing spondylitis–associated cervical fractures: a systematic review and meta-analysis
Authors: Govindarajan Vaidya , Bryant Jean-Paul , Perez-Roman Roberto J. , Wang Michael Y. 
Published: October 2021

OBJECTIVE
Cervical fractures in patients with ankylosing spondylitis can have devastating neurological consequences. Currently, several surgical approaches are commonly used to treat these fractures: anterior, posterior, and anterior-posterior. The relative rarity of these fractures has limited the ability of surgeons to objectively determine the merits of each. The authors present an updated systematic review and meta-analysis investigating the utility of anterior surgical approaches relative to posterior and anterior-posterior approaches.

METHODS
After a comprehensive literature search of the PubMed, Cochrane, and Embase databases, 7 clinical studies were included in the final qualitative and 6 in the final quantitative analyses. Of these studies, 6 compared anterior approaches with anterior-posterior and posterior approaches, while 1 investigated only an anterior approach. Odds ratios and 95% confidence intervals were calculated where appropriate.

RESULTS
A meta-analysis of postoperative neurological improvement revealed no statistically significant differences in gross rates of neurological improvement between anterior and posterior approaches (OR 0.40, 95% CI 0.10–1.59; p = 0.19). However, when analyzing the mean change in neurological function, patients who underwent anterior approaches had a significantly lower mean change in postoperative neurological function relative to patients who underwent posterior approaches (mean difference [MD] −0.60, 95% CI −0.76 to −0.45; p < 0.00001). An identical trend was seen between anterior and anterior-posterior approaches; there were no statistically significant differences in gross rates of neurological improvement (OR 3.05, 95% CI 0.84–11.15; p = 0.09). However, patients who underwent anterior approaches experienced a lower mean change in neurological function relative to anterior-posterior approaches (MD −0.46, 95% CI −0.60 to −0.32; p < 0.00001). There were no significant differences in complication rates between anterior approaches, posterior approaches, or anterior-posterior approaches, although complication rates trended lower in patients who underwent anterior approaches.

CONCLUSIONS
The results of this review and meta-analysis demonstrated the varying benefits of anterior approaches relative to posterior and anterior-posterior approaches in treatment of cervical fractures associated with ankylosing spondylitis. While reports demonstrated lower degrees of neurological improvement in anterior approaches, they may benefit patients with less-severe injuries if lower complication rates are desired.

Authors: Song Gang , Sun Liyong , Bao Yuhai , Liang Jiantao 
Published: October 2021

The main objectives of microsurgery for vestibular schwannoma are total tumor removal and preservation of facial and cochlear nerve function. For giant tumors, total tumor removal and facial nerve function preservation are challenging. The semisitting position has some advantages. In this video the authors show the removal of a giant vestibular schwannoma with the patient in a semisitting position. They demonstrate the advantages of the semisitting technique, such as the two-handed microsurgical dissection technique and a clear operative field. Finally, a small residual tumor in the internal auditory canal was removed by endoscopy. The patient’s facial function was House-Brackmann grade I at discharge.

Long-term degradation, damage and fracture in deep rock tunnels: A review on the effect of excavation methods
Authors: Frenelus Wadslin , Peng Hui , Zhang Jingyu 
Published: October 2021

Rocks are frequently host materials for underground structures, particularly for deep Tunnels. Their behavior plays a fundamental role in the overall stability of these structures. In fact, the erection of deep tunnels imposes rocks excavations around the defined routes. These excavations are generally carried out by various methods of which the most used are Drill-and-Blast (DB) and Tunnel Boring Machine (TBM). However, regardless of the tunnelling method used, the impacts such as the perturbation of the initial stress field in rocks and the release of the stored energy are always significant. The impacts produce damage, fractures and deformations which are generally time-dependent and influence the long-term stability of deep tunnels built in rocks. Thus, by considering the aforementioned excavation methods, this paper identifies, reviews and describes the relevant factors generated during and after rock excavations. Interestingly, such factors directly or indirectly influence the long-term stability and therefore the structural integrity of deep rock tunnels. In addition, some recommendations and proposals for future works are presented. This paper can provide useful references in understanding the degradations, damage and fractures generated by tunnelling methods and facilitate suitable actions to ensure long-term stability of deep underground structures.

Published: October 2021

INTRODUCTION: Essential thrombocythemia (ET) is an entity of classic Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs), characterized by thrombocytosis with megakaryocytic hyperplasia where in the thrombocytes are increased with abnormal function. Thrombotic events are seen frequently and represent the main cause of morbidity and mortality in patients with MPNs, mainly polycythemia vera and ET. This study has aimed to research the effects of clonally increased thrombocytes on plasma viscosity (PV) levels among patients with ET and the relationship between PV and thromboembolism history, according to the hypotheses about the effects of PV in thromboembolic events among patients with ET. METHODS: A total of 55 patients were enrolled in the study group, 18 of who had been newly diagnosed with ET according to 2016 World Health Organization criteria and had not previously been treated. 37 of them had already been diagnosed with ET and had been treated. There were 47 healthy volunteers in the control group. 5 cc blood samples were taken from the patients into tubes including an anticoagulant to measure their PV levels. RESULTS: PV of the control group was found to be lower than in the study group and both each patient groups ( p < 0.05). No relationship was found between the patient groups in terms of PV ( p = 0.404). The mean PV levels of the 16 patients with a history of thromboembolism and the 39 patients with no such history were 2.42±0.17 cP and 2.33±0.20 cP, respectively. The mean PV levels were found to be similar according to their history of thromboembolism in all patient groups and in treated patients ( p = 0.572 vs p = 0.991). CONCLUSION: We have found that PV levels were increased in clonally increased thrombocytes in patients with ET when compared with the control group. This is the first study in this field according to our knowledge.
EVALUATION OF THE THERAPEUTIC EFFECT OF THE COMBINED USE OF CRYOPRESERVED PLACENTA EXTRACT AND DICLOFENAC SODIUM IN EXPERIMENTAL RHEUMATOID ARTHRITIS BY HEMATOLOGICAL PARAMETERS
Authors: Hladkykh F. V. 
Published: October 2021

Relevance. Cryopreserved placenta extract (CPE) increase the resistance of the mucous membrane of the gastrointestinal tract to the damaging effects of nonsteroidal anti-inflammatory drugs. Preventive administration of CPE can reduce the ulcerogenic effect of meloxicam, ibuprofen, diclofenac sodium (DS) and others. There is evidence of CPE's own anti-inflammatory activity, which can be successfully combined with the pharmacological properties of nonsteroidal anti-inflammatory drugs, while improving their safety profile.
Objective: to characterize the therapeutic activity of the combined use of CPE and DS according to hematological parameters in the model of experimental rheumatoid arthritis (RA).
Materials and methods. Studies were performed on 28 nonlinear laboratory rats. The rats were divided into 4 groups: I (n = 7) – intact rats; II (n = 7) – rats with experimental RA; ІІІ (n = 7) – rats with experimental RA, treated with DN; IV (n = 7) – rats with experimental RA, treated with DN and CPE. Adjuvant arthritis was modeled by subplantar administration of complete Freund's adjuvant. Treatment was performed from 14 to 28 days. CPE was administered on days 14, 17, 20, 23 and 26, and DS – daily. Blood tests were performed on day 28 of the experiment.
Results. The combined use of CPE and DS is accompanied by a more pronounced leveling of inflammatory signs by hematological parameters – erythrocyte clotting rate decreased by 72.2% (p<0.001), and the number of leukocytes decreased by 54.81% (p<0.001) relative to rats with adjuvant arthritis without treatment. There was a leveling of signs of anemia of chronic inflammation – the level of hemoglobin and erythrocytes increased (p<0,001) by 17.6% and 36.8%, respectively, relative to rats with adjuvant arthritis without treatment.
Conclusions. The combined use of CPE and DS is superior in therapeutic activity to monotherapy with this nonsteroidal anti-inflammatory drug of experimental rheumatoid arthritis.
