Zoom-ryhmähaastattelun vuorovaikutusta rakentamassa: uusmaterialistisia tulkintoja verkkovälitteisestä kenttätyöstä
Authors: Hokka Johanna , Kurtti Elisa , Olsson Pia 
Published: June 2022

Verkkovälitteiset haastattelut ovat tarjonneet koronapandemian aikana yhden ratkaisun tutkimusaineiston tuottamiseksi kohtaamisiin liittyvien rajoitusten vaikuttaessa perinteisiin haastattelu- ja kenttätyömenetelmiin. Artikkelissa tarkastelemme, miten ryhmähaastattelu muotoutuu eri toimijoiden välisessä vuorovaikutuksessa, kun se toteutetaan Zoom-välitteisesti. Analyysissämme tarkastelemme verkkovälitteisten haastattelujen vuorovaikutusprosesseja haastattelijan, haastateltavan ja teknologian yhteistoimintana hyödyntäen uusmaterialistista ajattelua. Kysymme, miten viestintäteknologia muokkaa tutkimushaastattelutilanteita ja mitä viestintäteknologia tekee ymmärryksellemme tutkimushaastattelutilanteista. Analysoimme visuaalisen etnografian keinoin kolmea vuosina 2020–2021 järjestämäämme oppimiskahvilaa, joissa hyödynnettiin Zoomia.
Teknologian fasilitoivuuden vuoksi videovälitteiset vuorovaikutustilanteet ovat lähtökohtaisesti aina myös vuorovaikutusta teknologian kanssa. Analyysimme tuo yhtäältä esiin, kuinka aiheellista on kiinnittää huomiota niihin tapoihin, joilla teknologia ja ihmistoimijat tulevat haastattelutilanteessa yhteen. Toisaalta analyysimme herättää pohtimaan sitä, millä tavoin myös ihmistoimijoiden tavat vuorovaikuttaa ovat aineistojen muodostamisessa tilannekohtaisia ja uniikkeja. Näiden tekijöiden arvioiminen voi olla haasteellista mutta välttämätöntä eri haastattelumenetelmien toimivuutta harkittaessa.

Published: June 2022

The current study aims at investigating the effectiveness of using strategy-based instruction on the studentâ€™s listening achievement. This research applied quasi-experimental design, and the instruments were pretest and posttest. Both tests were about putting the pictures in order and form completion. Â Prior to strategy choice, this study utilized Posteriori Taxonomy of Strategies of Learning English Listening Skill (Zuhairi & Hidayanti, 2014) especially focusing on the use of eight strategy categories deployed by successful students (Hidayanti & Umamah, 2018). Gaining the result from Independent t-Test analysis, it was found out that the experimental group outperformed better than their counterparts in control group. Thus, Strategy-based instruction plays important role to enhance and improve the EFL learnersâ€™ listening skill.

Published: June 2022

INTRODUCCIÓN: La cirugía colorrectal laparoscópica mano asistida (CLMA) es un abordaje alternativo a la laparoscopia directa (LD) que requiere de un dispositivo específico para mantener el neumoperitoneo. Nuestro grupo describió una técnica original de doble guante como alternativa a este dispositivo. El objetivo del presente trabajo fue analizar los resultados de esta técnica comparándola con la técnica de LD.
MÉTODOS: Se analizó una serie consecutiva de pacientes sometidos a cirugías colorrectales laparoscópicas entre 2004 y 2020 en el Hospital Italiano de Bs, As, Argentina. Se realizó un modelo de regresión múltiple de selección progresiva y apareamiento por puntaje de propensión para analizar los resultados perioperatorios.
RESULTADOS: Los casos de CLMA (n=458) y LD (n=1692) fueron demográficamente similares. CLMA se asoció a un menor tiempo operatorio (170,3 vs 206,9 minutos, p<0.001). Dicha reducción fue más marcada en obesos (44.1 min), pacientes grandes (37.5 min), cirugías complejas (33.8 min) y en procedimientos realizados por cirujanos no entrenados (57,6 vs 31,6 minutos, p<0.001). CLMA resultó tener menor índice de conversión (5% vs 9.9%, p<0.001) con una razón de probabilidades ajustada de 0,45. No se hallaron diferencias en cuanto a estadía hospitalaria, morbimortalidad y readmisión.
CONCLUSIÓN: CLMA con doble guante es comparable a la LD manteniendo un tiempo operatorio reducido y bajo índice de conversión, particularmente en pacientes obesos sometidos a procedimientos complejos.
A taxonomy for brainstem cavernous malformations: subtypes of medullary lesions
Authors: Catapano Joshua S. , Rumalla Kavelin , Srinivasan Visish M. , Lawrence Peter M. , Larson Keil Kristen , Lawton Michael T. 
Published: June 2022

OBJECTIVE
Medullary cavernous malformations are the least common of the brainstem cavernous malformations (BSCMs), accounting for only 14% of lesions in the authors’ surgical experience. In this article, a novel taxonomy for these lesions is proposed based on clinical presentation and anatomical location.

METHODS
The taxonomy system was applied to a large 2-surgeon experience over a 30-year period (1990–2019). Of 601 patients who underwent microsurgical resection of BSCMs, 551 were identified who had the clinical and radiological information needed for inclusion. These 551 patients were classified by lesion location: midbrain (151 [27%]), pons (323 [59%]), and medulla (77 [14%]). Medullary lesions were subtyped on the basis of their predominant surface presentation. Neurological outcomes were assessed according to the modified Rankin Scale (mRS), with an mRS score ≤ 2 defined as favorable.

RESULTS
Five distinct subtypes were defined for the 77 medullary BSCMs: pyramidal (3 [3.9%]), olivary (35 [46%]), cuneate (24 [31%]), gracile (5 [6.5%]), and trigonal (10 [13%]). Pyramidal lesions are located in the anterior medulla and were associated with hemiparesis and hypoglossal nerve palsy. Olivary lesions are found in the anterolateral medulla and were associated with ataxia. Cuneate lesions are located in the posterolateral medulla and were associated with ipsilateral upper-extremity sensory deficits. Gracile lesions are located outside the fourth ventricle in the posteroinferior medulla and were associated with ipsilateral lower-extremity sensory deficits. Trigonal lesions in the ventricular floor were associated with nausea, vomiting, and diplopia. A single surgical approach was preferred (> 90% of cases) for each medullary subtype: the far lateral approach for pyramidal and olivary lesions, the suboccipital-telovelar approach for cuneate lesions, the suboccipital-transcisterna magna approach for gracile lesions, and the suboccipital-transventricular approach for trigonal lesions. Of these 77 patients for whom follow-up data were available (n = 73), 63 (86%) had favorable outcomes and 67 (92%) had unchanged or improved functional status.

CONCLUSIONS
This study confirms that the constellation of neurological signs and symptoms associated with a hemorrhagic medullary BSCM subtype is useful for defining the BSCM clinically according to a neurologically recognizable syndrome at the bedside. The proposed taxonomical classifications may be used to guide the selection of surgical approaches, which may enhance the consistency of clinical communications and help improve patient outcomes.

Published: June 2022

OBJECTIVE
Measuring costs across entire episodes of care, time-driven activity-based costing (TDABC) has recently been described as a novel cost accounting arm of value-based care organizations. Lean methodology is a system used to understand pathways of care at a granular level, allowing for standardization. The current work presents an attempt at combining the 2 methodologies to detect meaningful variation in a patient’s care following single-level spine fusion. The objective of this study was to evaluate the combination of TDABC and lean methodologies in detecting meaningful variability in time-based care in patients undergoing single-level spine fusion surgery.

METHODS
This study is a consecutive case series of patients who underwent single-level spine fusion performed by 1 of 5 fellowship-trained spine surgeons. Patients were diagnosed with either lumbar stenosis or spondylolisthesis. Additional inclusion criteria included inpatient stays from 1 to 3 days, discharge to home, and no readmission within 30 days of surgery. Patient demographic data were obtained. Time spent on activities for each personnel role was aggregated in 15-minute increments occurring preoperatively, intraoperatively, and postoperatively. Patients were analyzed in 3 groups based on the duration of their in-hospital stay.

RESULTS
Patients discharged on postoperative day (POD) 3 had statistically significantly more total time spent than those discharged on POD 2. Patients discharged on POD 1 had less total time than those in the former 2 groups. The amount of time spent with patients did not differ for personnel in either preoperative or postanesthesia care unit phases of care. There was a statistically significant difference in time spent in surgery for surgeons, anesthesia attendings, circulators, and scrub technicians.

CONCLUSIONS
In a healthcare setting run by lean methodology, TDABC may detect meaningful variability in an episode of care for single-level spine fusion. Clinicians and administrators can use this combination to allocate costs appropriately, optimize value care streams, and help improve patient care.
Evaluating a paradigm shift from anterior decompression and fusion to muscle-preserving selective laminectomy: a single-center study of degenerative cervical myelopathy
Authors: Kitamura Kazuya , de Dios Eddie , Bodon Gergely , Barany Laszlo , MacDowall Anna 
Published: June 2022

OBJECTIVE
Muscle-preserving selective laminectomy (SL) is an alternative to conventional decompression surgery in patients with degenerative cervical myelopathy (DCM). It is less invasive, preserves the extensor musculature, and maintains the range of motion of the cervical spine. Therefore, the preferred treatment for DCM at the authors’ institution has changed from anterior decompression and fusion (ADF), including anterior cervical discectomy and fusion (ACDF) and anterior cervical corpectomy and fusion (ACCF), toward SL. The aim of this study was to evaluate surgical outcomes before and after this paradigm shift with patient-reported outcome measures (PROMs), complications, reoperations, and cost-effectiveness.

METHODS
This study was a retrospective register-based cohort study. All patients with DCM who underwent ADF or SL at the authors’ institution from 2008 to 2019 were reviewed. Using ANCOVA, changes in PROMs from baseline to the 2-year follow-up were compared between the two groups, adjusting for clinicodemographic parameters, baseline PROMs, number of decompressed levels, and MRI measurements (C2–7 Cobb angle, C2–7 sagittal vertical axis [SVA], and modified K-line interval [mK-line INT]). The PROMs, including the European Myelopathy Score (EMS), the Neck Disability Index (NDI), and the EQ-5D, were collected from the national Swedish Spine Register. Complications, reoperations, and in-hospital treatment costs were also compared between the two groups.

RESULTS
Ninety patients (mean age 60.7 years, 51 men [57%]) were included in the ADF group and 63 patients (mean age 68.8 years, 41 men [65%]) in the SL group. The ADF and SL groups had similar PROMs at baseline. The preoperative MR images showed similar C2–7 Cobb angles (10.7° [ADF] vs 14.1° [SL], p = 0.12) and mK-line INTs (4.08 vs 4.88 mm, p = 0.07), but different C2–7 SVA values (16.2 vs 19.3 mm, p = 0.04). The comparison of ANCOVA-adjusted mean changes in PROMs from baseline to the 2-year follow-up presented no significant differences between the groups (EMS, p = 0.901; NDI, p = 0.639; EQ-5D, p = 0.378; and EQ-5D health, p = 0.418). The overall complication rate was twice as high in the ADF group (22.2% vs 9.5%, p = 0.049), while the reoperation rate was comparable (16.7% vs 7.9%, p = 0.146). The average in-hospital treatment cost per patient was $6617 (USD) for SL, $7046 for ACDF, and $12,000 for ACCF.

CONCLUSIONS
SL provides similar PROMs after 2 years, a significantly lower complication rate, and better cost-effectiveness compared with ADF.
Effects of rod diameter on kinematics of posterior cervical spine instrumented constructs: an ex vivo study

Published: June 2022

OBJECTIVE
Posterior cervical spine fixation is a robust strategy for stabilizing the spine for a wide range of spinal disorders. With the evolution of spinal implant technology, posterior fixation with lateral mass screws in the subaxial spine is now common. Despite interest in variable rod diameters to meet a wide range of clinical needs such as trauma, revision, and deformity surgery, indications for use of posterior cervical spine fixation are not clear. This laboratory investigation evaluates the mechanical stability and kinematic properties of lateral mass fixation with various commercially available rod diameters.

METHODS
The authors conducted an ex vivo experiment using 13 fresh-frozen human cervical spine specimens, instrumented from C3 to C6 with lateral mass screws, to evaluate the effects of titanium rod diameter on kinematic stability. Each intact spine was tested using a kinematic profiling machine with an optoelectrical camera and infrared sensors applying 1.5-Nm bending moments to the cranial vertebra (C2) simulating flexion-extension, lateral bending, and axial rotation anatomical motions. A compressive follower preload of 150 N was applied in flexion-extension prior to application of a bending moment. Instrumented spines were then tested with rod diameters of 3.5, 4.0, and 4.5 mm. The kinematic data between intact and surgical cases were studied using a nonparametric Wilcoxon signed-rank test. A multivariable, multilevel linear regression model was built to identify the relationship between segmental motion and rod diameter.

RESULTS
Instrumentation resulted in significant reduction in range of motion in all three rod constructs versus intact specimens in flexion-extension, lateral bending, and axial rotation (p < 0.05). The maximum reductions in segmental ROM versus intact spines in 3.5-, 4.0-, and 4.5-mm rod constructs were 61%, 71%, and 81% in flexion-extension; 70%, 76%, and 81% in lateral bending; and 50%, 60%, and 75% in axial rotation, respectively. Segmental motion at the adjacent segments (C2–3 and C6–7) increased significantly (p < 0.05) with increasing rod diameter. The 4.5-mm rod construct had the greatest increase in motion compared to the intact spine.

CONCLUSIONS
With increasing rod diameters from 3.5 to 4.0 mm, flexion-extension, lateral bending, and axial rotation across C3–6 were significantly reduced (p < 0.05). Similar trends were observed with a statistically significant reduction in motion in all anatomical planes when the rod diameter was increased to 4.5 mm. Although the increase in rod diameter resulted in a more rigid construct, it also created an increase (p < 0.05) in the kinematics of the adjacent segments (C2–3 and C6–7). Whether this increase translates into adverse long-term clinical effects in vivo requires further investigation and clinical assessment.

Background: The endosomal-lysosomal and autophagy (ELA) pathway may be implicated in the progression of Alzheimer’s disease (AD); however, findings thus far have been inconsistent. Objective: To systematically summarize differences in endosomal-lysosomal and autophagy proteins in the cerebrospinal fluid (CSF) of people with AD and healthy controls (HC). Methods: Studies measuring CSF concentrations of relevant proteins in the ELA pathway in AD and healthy controls were included. Standardized mean differences (SMD) with 95% confidence intervals (CI) between AD and healthy controls in CSF concentrations of relevant proteins were meta-analyzed using random-effects models. Results: Of 2,471 unique studies, 43 studies were included in the systematic review and meta-analysis. Differences in ELA protein levels in the CSF between AD and healthy controls were observed, particularly in lysosomal membrane (LAMP-1: NAD/NHC = 348/381, SMD [95% CI] = 0.599 [0.268, 0.930], I2 = 72.8%; LAMP-2: NAD/NHC = 401/510, SMD [95% CI] = 0.480 [0.134, 0.826], I2 = 78.7%) and intra-lysosomal proteins (GM2A: NAD/NHC = 390/420, SMD [95% CI] = 0.496 [0.039, 0.954], I2 = 87.7%; CTSB: NAD/NHC = 485/443, SMD [95% CI] = 0.201 [0.029, 0.374], I2 = 28.5%; CTSZ: NAD/NHC = 535/820, SMD [95% CI] = –0.160 [–0.305, –0.015], I2 = 24.0%) and in proteins involved in endocytosis (AP2B1:NAD/NHC = 171/205, SMD [95% CI] = 0.513 [0.259, 0.768], I2 = 27.4%; FLOT1: NAD/NHC = 41/45, SMD [95% CI] = –0.489 [–0.919, –0.058], I2 <0.01). LC3B, an autophagy marker, also showed a difference (NAD/NHC = 70/59, SMD [95% CI] = 0.648 [0.180, 1.116], I2 = 38.3%)), but overall there was limited evidence suggesting differences in proteins involved in endosomal function and autophagy. Conclusion: Dysregulation of proteins in the ELA pathway may play an important role in AD pathogenesis. Some proteins within this pathway may be potential biomarkers for AD.

Authors: Semko Inga , Mokiienko Iuliia 
Published: June 2022

Modern education is undergoing a time of fundamental change: it is progressing, changing and being filled with new types of educational services. All types of activities of higher education institutions can be considered through the prism of project activities, especially educational projects. Educational projects of higher education institutions face a set of different risk groups, which differ in place and time of occurrence, the degree of impact on the project, the consequences, the composition of internal and external factors. Therefore, a very important area of research in educational activities is to reveal the nature and structure of risks of educational projects, features, factors on which the successful implementation of projects in educational institutions depends. The author analyzes the key positions on this issue: systematized and singled out groups of external and internal risks of educational activities, comprehensively revealed the system of external risks and proposed possible mechanisms for responding to them, outlined the range of losses (economic, social, political and pedagogical) that are the result of risky events; systematized risk groups (external and internal) and their factors of influence that are characteristic of educational projects; assessed risks according to the probability of impact on the project, identification of critical points with a list of unacceptable risks; the matrix of probability of risks importance with the subsequent definition of the most priority risk events is constructed. For effective implementation of educational activities in the field of higher education, it is necessary for higher education institutions to identify risks beforehand, which will reduce uncertainty in the educational institutions activities, determine the direction of movement, which should focus on management, personnel, methodological, research, financial, technological and organizational resource.
