Background
The ability to walk is a key issue for independent old age. Optimizing older peoples’ opportunities for an autonomous and active life and reducing health disparities requires a better understanding of how to support independent mobility in older people. With increasing age, changes in gait parameters such as step length and cadence are common and have been shown to increase the risk of mobility decline. However, gait assessments are typically based on laboratory measures, even though walking in a laboratory environment may be significantly different from walking in outdoor environments.

Objective
This project will study alterations in biomechanical features of gait by comparing walking on a treadmill in a laboratory, level outdoor, and hilly outdoor environments. In addition, we will study the possible contribution of changes in gait between these environments to outdoor mobility among older people.

Methods
Participants of the study were recruited through senior organizations of Central Finland and the University of the Third Age, Jyväskylä. Inclusion criteria were community-dwelling, aged 70 years and older, able to walk at least 1 km without assistive devices, able to communicate, and living in central Finland. Exclusion criteria were the use of mobility devices, severe sensory deficit (vision and hearing), memory impairment (Mini-Mental State Examination ≤23), and neurological conditions (eg, stroke, Parkinson disease, and multiple sclerosis). The study protocol included 2 research visits. First, indoor measurements were conducted, including interviews (participation, health, and demographics), physical performance tests (short physical performance battery and Timed Up and Go), and motion analysis on a treadmill in the laboratory (3D Vicon and next-generation inertial measurement units [NGIMUs]). Second, outdoor walking tests were conducted, including walking on level (sports track) and hilly (uphill and downhill) terrain, while movement was monitored via NGIMUs, pressure insoles, heart rate, and video data.

Results
A total of 40 people (n=26, 65% women; mean age 76.3, SD 5.45 years) met the inclusion criteria and took part in the study. Data collection took place between May and September 2022. The first result is expected to be published in the spring of 2024.

Conclusions
This multidisciplinary study will provide new scientific knowledge about how gait biomechanics are altered in varied environments, and how this influences opportunities to participate in outdoor activities for older people.

Authors: Yttergård Vegard Alexander Olsen , Foshaug Vennebo Kirsten 
Published: March 2024

Denne artikkelen rapporterer fra en studie der vi undersøker ledelsespraksiser i oppstarten av skolers arbeid for utvikling av tilpasset opplæring iverksatt på initiativ fra skoleeieren. Studien har et aksjonsforskningsdesign med fire deltakende skoler og ledergrupper. Samlet viser studien hvordan ledelsespraksiser som er preget av distribuert og samhandlende «tettpå-ledelse», kjennetegnet av kontekstsensitive og verdibevisste handlingsorienteringer og -valg, utvikles gjennom oppstartsarbeidet. Ledergruppene, med rektorene i spissen, forankrer arbeidet i skolenes profesjonsfellesskap gjennom å sette verdier samt skolenes praktisering av tilpasset opplæring i sentrum for felles meningsskapende aksjoner, med klare koblinger til skoleeierens plan. Basert på funn i studien diskuterer vi hvordan ledelsespraksisene kan få betydning for det videre utviklingsarbeidet og utvikling i skolene, før vi avslutningsvis konkluderer og peker på noen av studiens implikasjoner og begrensninger.
ENGLISH ABSTRACT
School leadership practices in the initial phase of schools’ work for developing adapted education
This article reports on a study in which we investigate school leadership practices for the development of adapted education, as they are expressed in the initial phase of schools’ development work, which is undertaken at the initiative of local educational authorities. The study has an action research design with four participating schools and school leadership groups. Overall, the study shows how leadership practices that are characterised by distributed and interactive “close-up” leadership as well as by context-sensitive and value-conscious action orientations and choices are developed through the initial phase. The work of the leadership groups, led by the principals, is anchored in the schools’ professional community by focusing on values and the schools’ practice of adapted education in joint meaning making actions with clear links to the plan from the local educational authorities. Based on the findings of the study, we discuss how leadership practices can have an impact on further development work and development in the schools before concluding and pointing out some of the study’s implications and limitations.

Published: March 2024

This paper presents a discussion of Radcliffe’s pedagogy-space-technology (PST) framework for the development, implementation, and evaluation of learning spaces in light of Merleau-Ponty’s Phenomenology of Perception. The following research questions have guided the theoretical discussion: In which ways can Merleau-Ponty’s body-subject phenomenology enlighten Radcliffe’s framework? How can Merleau-Ponty’s body-subject paradigm be integrated into the development and implementation of hybrid learning environments? The reference to an exploratory case study within the frame of a larger research project will support the theoretical argumentation. In the study, the genesis of an innovative learning environment linked to a cross-institution master’s program located at two Norwegian universities will serve as an example.

Introduction. While developing the algorithms for diagnosis and treatment of patients with thermal injury, an injury outcome prediction index with the best predictive properties should be used.Aim. To compare the predictive properties of the Revised Frank Index and other specialized indices.Material and methods. A retrospective observational study included 307 patients with thermal injury, of whom 80 (26%) died. We compared the discriminatory ability, as well as sensitivity, specificity, positive predictive value and negative predictive value, the accuracy of the diagnostic test in relation to predicting a fatal outcome for 8 specialized prediction indices: RFI, FI, Baux, RBS, PBI, ABSI, BOBI, and Ryan.Results. RFI showed the largest area under the ROC curve: 0.942 [0.913–0.971], other indices had a smaller area: FI 0.827 [0.768–0.886], Baux 0.860 [0.811–0.909], RBS 0.891 [0.848–0.933], PBI 0.893 [0.848–0.937], ABSI 0.838 [0.786–0.890], BOBI 0.865 [0.819–0.910], Ryan 0.816 [0.764–0.869]. The Ryan index had the highest sensitivity (95%), but its specificity (49%) was the lowest, and the proportion of false positive results was 60%. The RBS index had high sensitivity (84%) and specificity (80%), but the false positive rate was 40%. The RFI and PBI indices showed similar sensitivity (81%), however, the proportion of false positive results for RFI (23%) was lower than that of PBI (39%) and all other indices, and the RFI accuracy in predicting the outcome was the highest among the other indices, making 89%.Conclusion. The predictive properties of the Revised Frank Index are better than those of other specialized indices.

Published: March 2024

Background. Postoperative analgesia in kidney transplant recipients is challenging due to potential nephrotoxicity of nonsteroidal anti-inflammatory drugs and the reduced clearance of opioid metabolites during transient renal impairment. Opioid-sparing multimodal postoperative analgesia using regional analgesia methods could provide better pain control and early activation after kidney transplantation.Aim. To evaluate the clinical results of treatment using regional pain management methods in kidney transplant recipients.Material and methods. A single-center study was conducted at Republican Research Center of Emergency Medicine from 2020 to 2022. The study included 97 patients who underwent heterotopic kidney transplantation from a living related donor. Patients were divided into 3 groups. In group 1 (31 patients), general anesthesia was used. For postoperative analgesia opioid analgesics in combination with metamizole 1000 mg were used. In group 2 (33 recipient patients), a combination of general anesthesia and open transversus abdominis plane block was used. In group 3 (33 recipient patients), a combination of general anesthesia and erector spine plane block was performed. Opioid analgesics were used as a "rescue analgesia" when necessary. The primary study end points were the pain intensity assessed by a visual analogue scale and opioid consumption on the first day after surgery. Secondary endpoints were the time of intestinal motility recovery, the presence of nausea and vomiting, the Intensive Care Unit length of stay and the hospital length of stay.Results. Pain intensity 6 hours after surgery in patients of group 1 was 13.5% and 24.6% higher than in patients of group 2 and 3, respectively. In group 2, pain intensity was 12.8% higher compared to group 3 (p=0.0017). At 12 hours after surgery, the pain intensity was 42% higher in group 1 compared to group 2 and group 3 (p<0.0001). After 18 hours, the pain score in group 3 was 48.5% and 35.7% lower compared to groups 1 and 2, respectively (p<0.0001 and p=0.0016). 24 hours after surgery, the sensation of pain was 18.6% and 65.3% higher in group 1 compared to groups 2 and 3 (p<0.0001). The mean dose of narcotic analgesic equivalent to morphine in group 1 was 22.6±8.6 mg, which was 18.5% higher than in group 2 patients. In group 3, it was 12.0±4.3 mg and was 47% lower compared to group 1 (p<0.0001) and 34.7% lower compared to group 2 (p<0.0001) (all comparisons are statistically significant). The adequacy of analgesia and less opioid consumption contributed to the absence of postoperative nausea and vomiting in 75% of cases, early restoration of intestinal motility in 63% compared with the group of patients where opioid analgesics were used for postoperative pain relief.Conclusion. The combined use of general anesthesia and erector spine plane block may be recommended as a method of effective perioperative analgesia in kidney transplantation.

Introduction. When performing osteoplastic craniotomy, there is a need to fill the diastasis between the skull bone and the explanted bone fragment. Grafts based on allogeneic bone chips and collagen (bone-plastic material) may be very effective for cranial bone repair in diastasis area.Aim. To evaluate the safety and clinical efficacy of osteoplastic material during the osteoplastic craniotomy.Material and methods. A retrospective and prospective clinical study was conducted at the N.V. Sklifosovsky Research Institute for Emergency Medicine and included 12 patients treated in Urgent Neurosurgery Department with diagnoses suggesting the need for craniotomy. Allogenic osteoplastic material was obtained from a 0.7-0.9% solution of type I collagen and spongy bone chips with a fraction size of 315-630 microns. Osteoplastic material grafts were used intraoperatively at the cranioplastic stage of the operation after the main stages had been completed. The efficacy and safety of the use of osteoplastic material were evaluated clinically and radiologically in the early postoperative period.Results. In the early postoperative period, the study patients had no pyo-septic complications, severe pain or soft tissue swelling. All patients were discharged from the hospital in satisfactory condition to be followed-up by the physician or neurologist at the out-patient facility. The computed tomography performed in the early postoperative period visualized the diastasis lines along the bone flap line in the comparison group patients (without osteoplastic material); and in the main group, the osteoplastic material was clearly visualized. At computed tomography of the skull performed after 6–9 months and after 2–18 months, the signs of bone tissue consolidation were visualized in the patients of the main group. The radiodensity of the autologous bone flap in both groups did not significantly change at any periods. In the diastasis area, the radiodensity of diastasis in the main group was significantly higher than in the comparison group. After 1-1.15 years the radiodensity values in the diastasis area increased by average of 1.95 times (p<0.05) in the patients of the main group, while in the patients without osteoplastic material, this parameter did not significantly change during the entire follow-up period.Conclusions. In patients with intraoperative cranioplasty osteoplastic material grafts did not cause complications in the early and late postoperative period. Intraoperative cranioplasty performed with using osteoplastic allogeneic material caused no complications in either early or late postoperative periods. The presence of osteoplastic material contributed to the consolidation of the autologous bone flap and healthy bone.

Background. In many countries, there is an increase in the number of poisoning with antihypertensive and antiarrhythmic drugs taken either accidentally or for suicidal purposes. The mortality rate for these poisonings reaches 6.5%.The aim of the study was to analyze the causes of fatal outcomes in patients with acute poisoning with hypotensive and antiarrhythmic drugs.Material and methods. The inpatient medical records (Form No. 003/y), autopsy reports of forensic chemical and forensic histological studies of 80 people who died from acute poisoning with hypotensive and antiarrhythmic drugs at the N.V. Sklifosovsky Research Institute for Emergency Medicine for the period from 2011 to 2020 were analyzed.Results. The age of patients with acute poisoning with antihypertensive and antiarrhythmic drugs ranged from 16 to 94 years, of which 85% of patients were over 60 years old. Women made up 70%. Twenty five patients died in the toxicogenic stage of poisoning, other 55 died in the somatogenic stage. The causes of poisoning were the intake of hypotensive drugs (mainly calcium channel blockers) in 67% of cases, the intake of antiarrhythmic drugs from the group of beta-blockers in 33%. Poisoning on suicidal intent was recorded in 81.2% of cases. The main causes of death in the toxicogenic stage of poisoning were the following (listed in order of decreasing incidence): exotoxic shock, primary cardiotoxic effect, acute cardiovascular insufficiency. The main cause of patient death in the somatogenic stage was pneumonia.Conclusion. Acute poisoning with antihypertensive and antiarrhythmic drugs, in the vast majority of cases, occurs in patients over 60 years of age. Suicidal attempts make the main cause of poisoning. The main cause of death in the toxicogenic stage of poisoning is exotoxic shock, that one in the somatogenic stage is nosocomial pneumonia.

Published: March 2024

Background. The significance of the problem of acute pancreatitis is due to an increase in the incidence with an increase in the number of common forms of pancreatic necrosis, accompanied by a high incidence of severe complications.Aim. To determine the effect of regional application of mesenchymal stromal cells on the systemic manifestations of severe acute experimental pancreatitis.Material and methods. This experimental study was carried out on 42 adults Wistar rats. Acute pancreatitis was induced by administering 0.3 ml of 5% solution of non-ionic polyethylene glycol octylphenol ether detergent into the caudal part of the pancreas. The animals were randomly divided into 4 groups: Group I (n=6) consisting of intact animals, Group II (control group) (n=12) of rats with untreated pancreatitis, Group III (n=12) of rats with pancreatitis treated: anesthesia + infusions of 0.9% sodium chloride solution (saline), and Group IV (n=12) of rats with pancreatitis treated: anesthesia + infusions of saline + regional application of mesenchymal stromal cells. Animals were taken out of the experiment by euthanasia on the 3rd and 7th day. The hematological parameters, markers of systemic manifestation of the pathological process (pancreatic amylase, aspartate aminotransferase, alanine aminotransferase, urea, creatinine), markers of endogenous intoxication (lipid peroxidation activity, nitric oxide level), markers of systemic inflammatory response (C-reactive protein, tumour necrosis factor-alpha, interleukin-6) have been evaluated.Results. The application of mesenchymal stromal cells in the early stages of acute pancreatitis made a favourable effect on the platelet count, the level of glycemia, helped to reduce the content of endogenous intoxication elements (malonic dialdehyde, nitric oxide) and of those of the systemic inflammatory response (interleukin-6, tumor necrosis factor-α, C-reactive protein), which are key links in the pathogenesis of severe acute pancreatitis.Conclusion. Comparison of different treatment regimens for acute experimental pancreatitis has shown that the early use of mesenchymal stromal cells has a systemic positive effect and confirms the therapeutic efficacy of the method in the treatment of this disease.
