We synthesized samarium oxotellurites SmMTeO4.5 (M — Mg, Ba) by the method of ceramic technology with solid-phase interaction (800–1200 °С) of Sm2O3 and TeO2 oxides with MgCO3 and BaCO3 carbonates. The compounds were characterized by X-ray and electrophysics methods. It has been established that the synthesized compounds crystallize in the tetragonal syngony with the following crystallographic characteristics: SmMgTeO4.5 — a = 12.226; c = 5.783 Å, V0un.cell = 864.38 Å3, Z = 4, ρxray. = 2.876, ρpycn. = (2.874±0.002) g∙cm-3; SmBaTeO4.5 — a = 12.717; с = 6.132Å, V0un.cell = 991.62Å3, Z = 4, ρxray. = 3.264, ρpycn. = (3.260±0.004) g∙cm-3; for both tellurites α = β = γ = 90°. The experimental and calculated values of 2 Th and d-sp, X-ray and pycnometric densities, as well as theoretical and experimental values of unit cell volumes are agreed satisfactorily. Thus, we can confirm correctness and reliability of the results of indexing X-ray patterns of new samarium oxotellurites. We found that increase in the ionic radii from Mg to Ba increases the lattice parameters of the synthesized oxotellurites. Oxotellurites are crystallized in the structural types of distorted perovskite Pm3m. Based on the given study samarium oxotellurites can have semiconductor and ferroelectric properties.

A Tale of Two Languages in Blogging: Code-Switching Analysis in Pakistani Blogosphere
Authors: Fatima Kanwal , Qadir Samina Amin
Published: April 2023

Computer-Mediated Communication (CMC) have brought about a new medium for information sharing and communication and weblogs are becoming more and more popular in the virtual sphere. The process of code- switching can be traced in this fast evolving medium of communication. This paper aims at investigating the existence of code-switching patterns by examining the categories and frequency of Urdu code-switches in Pakistani English weblogs authored by Pakistani bloggers. The quantitative and qualitative approaches were used in this study. The blog entries of 10 Pakistani bloggers were analyzed by using the descriptive research paradigm. The findings illustrated that the linguistic choices of Pakistani bloggers as bilingual internet users are living in between two worlds, two cultures, and two languages which they employ in this mode of communication to fully express themselves. The findings showed the linguistic features that are particular to the context of CMC. The study concluded that the presence of code-switching in CMC have to be considered and treated as a unique and different entity from spoken form or written form of code-switching to capture its fundamental attributes.

Transitivity in Pakistani English: A Corpus-based Approach towards Mapping Frequency Profiles
Authors: Tehseem Tazanfal , Talaat Mubina
Published: April 2023

This paper aims at building frequency profiles based on transitivity patterns of a small number of text corpora belonging to Pakistani English newspaper editorials. The profiles have been built by using UAM Corpus Tool (O’ Donnell, 2008) to explore transitivity features. The empirical analysis then has been compared with the frequency profiles of English language (Matthiessen, 2006 and Stubbs, 1996) to establish common features. The present work draws inspiration by Michael Halliday who is known as one of the pioneer corpus linguists since his early work on the Chinese language (Halliday 1956, cited in Halliday 1993). Mapping his (ibid) study on the BNC model he concluded that the relative frequencies of past and non-past are about 50-50 and the relative frequencies of positive and negative are about 9-1 (reported in Halliday 1993). Similarly, the present study looks closer to Standard English, and this is partially because the editorials are written by professional writers, and are well edited before printing.
Link between both infratentorial and supratentorial intracranial pressure burdens and final outcome in patients with infratentorial brain injury
Authors: Petr Ondra , Ho Wing Mann , Petutschnigg Thomas , Krigers Aleksandrs , Treichl Stephanie Alice , Preuss-Hernández Christian , Brawanski Konstantin , Helbok Raimund , Thomé Claudius
Published: April 2023

OBJECTIVE

Increased intracranial pressure (ICP) is most likely not being transmitted uniformly within the cranium. The ICP profiles in the supra- and infratentorial compartments remain largely unclear. Increased ICP in the cerebellum, however, is insufficiently captured by supratentorial ICP (ICPsup) monitoring due to compartmentalization through the tentorium. The authors hypothesized that additional infratentorial ICP (ICPinf) monitoring can be clinically valuable in selected patients. The aims of this study were to demonstrate the safety and feasibility of ICPinf monitoring and to investigate the influence of the ICPinf on clinical outcome in a real-world setting.

METHODS

Fifteen consecutive patients with posterior fossa (PF) lesions requiring surgery and anticipated prolonged neurointensive care between June 2019 and December 2021 were included. Simultaneous ICPsup and ICPinf were recorded. ICP burden was defined as a 15-minute interval with a mean ICP > 22 mm Hg. The Glasgow Outcome Scale score was assessed after 3 months.

RESULTS

The mean ICPinf was substantially higher compared with ICPsup throughout the entire period of ICP recording (16.08 ± 4.44 vs 10.74 ± 3.6 mm Hg, p < 0.01). ICPinf was significantly higher in patients with unfavorable outcome when compared with those with favorable outcome (mean 17.2 ± 4.1 vs 11.4 ± 3.5 mm Hg, p < 0.05). Patients with unfavorable outcome showed significantly higher ICPinf burden compared with those with favorable outcome (mean 40.6 ± 43.8 vs 0.3 ± 0.4 hours, p < 0.05). Neither absolute ICPsup nor ICPsup burden was significantly associated with unfavorable outcome (p = 0.13). No monitoring-associated complications occurred.

CONCLUSIONS

Supplementary ICPinf monitoring is safe and reliable. There is a significant transtentorial pressure gradient within the cranium showing elevated ICPs in the PF. Elevated ICP levels in the PF were strongly associated with unfavorable neurological outcome irrespective of ICPsup values.

Authors: Asmaro Karam , Zhang Michael , Rodrigues Adrian J. , Mohyeldin Ahmed , Vigo Vera , Nernekli Kerem , Vogel Hannes , Born Donald E. , Katznelson Laurence , Fernandez-Miranda Juan C.
Published: April 2023

OBJECTIVE

Pituitary tumors (PTs) continue to present unique challenges given their proximity to the cavernous sinus, whereby invasive behavior can limit the extent of resection and surgical outcome, especially in functional tumors. The aim of this study was to elucidate patterns of cavernoinvasive behavior by PT subtype.

METHODS

A total of 169 consecutive first-time surgeries for PTs were analyzed; 45% of the tumors were functional. There were 64 pituitary transcription factor–1 (PIT-1)–expressing, 62 steroidogenic factor–1 (SF-1)–expressing, 38 T-box transcription factor (TPIT)–expressing, and 5 nonstaining PTs. The gold standard for cavernous sinus invasion (CSI) was based on histopathological examination of the cavernous sinus medial wall and intraoperative exploration.

RESULTS

Cavernous sinus disease was present in 33% of patients. Of the Knosp grade 3 and 4 tumors, 12 (19%) expressed PIT-1, 7 (11%) expressed SF-1, 8 (21%) expressed TPIT, and 2 (40%), were nonstaining (p = 0.36). PIT-1 tumors had a significantly higher predilection for CSI: 53% versus 24% and 18% for TPIT and SF-1 tumors, respectively (OR 6.08, 95% CI 2.86–13.55; p < 0.001). Microscopic CSI—defined as Knosp grade 0–2 tumors with confirmed invasion—was present in 44% of PIT-1 tumors compared with 7% and 13% of TPIT and SF-1 tumors, respectively (OR 11.72, 95% CI 4.35–35.50; p < 0.001). Using the transcavernous approach to excise cavernous sinus disease, surgical biochemical remission rates for patients with acromegaly, prolactinoma, and Cushing disease were 88%, 87%, and 100%, respectively. The granule density of PIT-1 tumors and corticotroph functional status did not influence CSI.

CONCLUSIONS

The likelihood of CSI differed by transcription factor expression; PIT-1–expressing tumors had a higher predilection for invading the cavernous sinus, particularly microscopically, compared with the other tumor subtypes. This elucidates a unique cavernoinvasive behavior absent in cells from other lineages. Innovative surgical techniques, however, can mitigate tumor behavior and achieve robust, reproducible biochemical remission and gross-total resection rates. These findings can have considerable implications on the surgical management and study of PT biology and behavior.
Safety of discontinuing antiplatelet therapy 12–24 months after stent-assisted coil embolization: a multicenter retrospective study
Authors: Kim Chang Hyeun , Hong Noah , Rhim Jong-Kook , Mun Jong Hyeon , Lim Jeongwook , Choi Hyun Ho , Kim Young Ha , Lee Sang Weon , Cho Young Dae
Published: April 2023

OBJECTIVE

Antiplatelet medication is required after stent-assisted coil embolization (SACE) to avoid thromboembolic complications. Currently, there is no consensus on how long the antiplatelet agent should be maintained. The authors investigated clinical outcomes in patients who discontinued their antiplatelet agent 12–24 months after SACE.

METHODS

Data were retrieved from a prospective database for 373 consecutive patients with SACE at 6 institutions who discontinued antiplatelet therapy 12–24 months after SACE. Thromboembolic complications associated with discontinuation were defined as neurological or radiographic ischemia that occurred within 6 months after discontinuation of the antiplatelet agent; the lesion had to be correlated with the territory of the stented artery.

RESULTS

The mean time until discontinuation of the antiplatelet medication was 15.8 ± 4.7 months after SACE (12–18 months, n = 271; 19–24 months, n = 102). The most common location of treated aneurysms was the internal carotid artery (n = 223, 59.8%). A laser-cut open-cell stent was most commonly applied (n = 236/388, 60.8%), followed by laser-cut closed-cell stents (n = 119, 30.7%) and braided closed-cell (n = 33, 8.5%); double stenting was applied in 15 aneurysms. There were no patients who experienced cerebral ischemia related to discontinuation of antiplatelet medications, except for 1 patient at high risk of ischemia (0.27%, 95% CI 0.01%–1.48%).

CONCLUSIONS

These results suggest that it may be safe to discontinue antiplatelet medication after SACE in patients at low risk for ischemia, and that it appears safe to discontinue the agent at approximately 15 months after the procedure. Large cohort-based prospective studies or randomized clinical trials are warranted to confirm these results.
Surgical treatment of craniovertebral junction instability in children with Down syndrome: a systematic review
Authors: Isaacs Albert M. , Narapareddy Ashruta , Nam Andrew , Hutcheson Kasey , Stone Michelle , Bonfield Christopher M.
Published: April 2023

OBJECTIVE

Down syndrome (DS) affects 1 in 700 live births and approximately one-third of patients develop craniovertebral junction (CVJ) instability, diagnosed by clinical examination and radiological measures such as the atlantodens interval (ADI) and space available for the cord (SAC). Patients with symptomatic CVJ instability are at increased risk for spinal cord injury. There are no guidelines for surgical management of CVJ instability in DS, the existing literature is sparse, and there is a lack of consistent pediatric data. This systematic review aimed to synthesize practice patterns of the surgical management of CVJ stability in pediatric DS patients to facilitate future standardization of care.

METHODS

Peer-reviewed studies reporting surgical management of CVJ instability in pediatric DS patients were systematically reviewed. Inclusion criteria were studies reporting primary data on patients younger than 18 years with DS, who had CVJ instability evaluation and underwent surgical treatment. Bias risk was assessed. Descriptive statistics of the independent patient data were presented. Interval variables were analyzed using the Wilcoxon rank-sum test.

RESULTS

Of 1056 records, 38 studies were included. Of the included patients, 169 (6%) underwent surgery. The surgical indication was symptomatic, radiologically confirmed CVJ instability in 81% of the patients, presenting with myelopathy (30%), weakness (25%), abnormal gait (24%), torticollis (15%), and neck pain (14%). A cutoff of ADI ≥ 4 mm or SAC ≤ 14 mm, cord compression, cord signal change, and anomalous bony anatomy were used in diagnosing CVJ instability. Surgical approaches focused on internal fixation with posterior occipitocervical or atlantoaxial instrumented fusion in 57% and 44% of patients, respectively. Autograft, wiring, and allograft constructs were used in 48%, 45%, and 9% of patients. Anterior cervical approaches were performed in 6% of patients. Preoperative and postoperative external orthoses were used in approximately 50% of patients. The surgical mortality rate was 3%, and the complication rate was 36%.

CONCLUSIONS

Assessment of CVJ instability in DS is based on radiographic and clinical factors. Surgery is recommended if symptoms are present, and the procedure type depends on patient factors, degree of instability, anomalous bony anatomy, and reduction results to relieve cord compression. Most commonly, posterior instrumented fusion is used. However, further research is required to determine the strength of evaluation methods, create standardized guidelines for evaluation and surgical treatment, and investigate the long-term results of different surgical techniques.
Establishment of a novel risk prediction model for recompression of augmented vertebrae at the thoracolumbar junction and modified puncture technique for prevention: a multicenter retrospective study
Authors: Yu Weibo , Jiang Xiaobing , Zhang Haiyan , Yao Zhensong , Zhong Yuanming , Tang Fubo , Cai Daozhang
Published: April 2023

OBJECTIVE

Recompression of augmented vertebrae (RCAV) is often seen after percutaneous kyphoplasty (PKP), especially at the thoracolumbar junction. The authors aimed to develop and validate a risk prediction model (nomogram) for RCAV and to evaluate the efficacy of a modified puncture technique for RCAV prevention after PKP for thoracolumbar osteoporotic vertebral fractures (OVFs).

METHODS

Patients who underwent PKP for single thoracolumbar OVFs (T10–L2) between January 2016 and October 2020 were reviewed and followed up for at least 2 years. All patients were randomly divided into a training group (70%) and a validation group (30%). Relevant potential data affecting recompression were collected. Predictors were screened by using binary logistic regression analysis to construct the nomogram. Calibration and receiver operating characteristic curves were used to evaluate the consistency of the prediction models. Finally, the efficacy of the modified puncture technique for prevention of RCAV in OVF patients with a preoperative intravertebral cleft (IVC) was further demonstrated through binary logistic regression analysis.

RESULTS

Overall, 394 patients were included and 116 of them (29.4%) sustained RCAV. The independent risk factors included decreased bone mineral density, lower level of serum 25-hydroxy vitamin D3, larger C7–S1 sagittal vertical axis (SVA), preoperative IVC, and solid-lump cement distribution. The area under the curve (AUC) of the prediction model was 0.824 in the training group and 0.875 in the validation group patients. The calibration curve indicated the predictive power of this nomogram, with the preoperative IVC having the highest prediction accuracy (AUC 0.705). The modified puncture technique significantly reduced the incidence of RCAV by enhancing bone cement distribution into a sufficiently diffused distribution in OVF patients with preoperative IVC.

CONCLUSIONS

The nomogram prediction model had satisfactory accuracy and clinical utility for identification of patients at low and high risk of postoperative RCAV. Patients at high risk of postoperative RCAV might benefit from the target puncture technique and vitamin D supplementation as well as effective antiosteoporotic therapies.

One of the economic values of plants is that they can be used as medicine. Indonesian people since ancient times have used plants as traditional medicine. This knowledge has been passed down from generation to generation and there are differences between regions. This is due to differences in customs and experiences of people who use traditional medicine. Based on this, it is necessary to carry out an inventory or record of plants that act as medicines so that they can be properly documented. The purpose of this study was to obtain data on the types of plants used as traditional medicine by the local community. This research was conducted in West Pussui Village, Luwo District, Kab. Polewali Mandar, West Sulawesi. The method used is explorative which is descriptive qualitative in nature. The data collection technique used Participatory Rural Appraisal (PRA), through in-depth interviews covering the types of plants that can be used as medicine, their uses and how to mix the plants used. In addition to interviews, direct observation was also carried out to see the conditions at the research location. The technique of selecting respondents was done by snowball sampling. Data from interviews and observations were then presented in the form of pictures and tables and then analyzed using descriptive qualitative. The results showed that the people of the Mandar tribe used kirinyuh, guava, soursop, jatropha banana, cocoa duck, papaya, black turmeric, moringa, coconut, secang wood, bitter melon, meniran, lime, purslane and breadfruit as traditional medicine to treat various kinds of diseases. The part of the plant that is most widely used to treat diseases is the leaf with a percentage of 50%.
