Assessment of forces during side-posture adjustment with the use of a table-embedded force plate: Reference values for education
Authors: Russell Brent S. , Owens Edward F. , Hosek Ronald S. , Dever Lydia L. , Weiner Michael T. 
Published: September 2023

ABSTRACT

Objective
Force-sensing treatment tables are becoming more commonly used by chiropractic educational institutions. However, when a table-embedded force platform is the sole measurement method, there is little information available about what force-time values instructors and students should expect for side-posture spinal manipulative thrusts. The purpose of this report is to provide force-time values recorded with such a system during side-posture manipulation with human recipients.

Methods
Student volunteers were examined by and received lumbar or pelvic side-posture manipulation from experienced chiropractors who were diplomates of the Gonstead Clinical Studies Society. Forces were recorded using proprietary software of a Bertec force platform; force and time data were analyzed with a custom-programmed software tool in Excel.

Results
Seven doctors of chiropractic performed 24 thrusts on 23 student recipients. Preload forces, averaging 69.7 N, and thrust loading duration, averaging 167 milliseconds, were similar to previous studies of side-posture manipulation. Peak loads were higher than previous studies, averaging 1010.9 N. Other variables included prethrust liftoff force, times from thrust onset to peak force and peak load to resolution of thrust, and average rates of force loading and unloading.

Conclusion
The values we found will be used for reference at our institution and may be useful to instructors at other chiropractic educational institutions, in the teaching of lumbar side-posture manipulation. A caveat is that the values of this study reflect multiple sources of applied force, not solely the force applied directly to the spine.
Association of pain neurophysiology knowledge and application amongst UK chiropractic students: A cross-sectional study
Authors: Nordbo Kajsa , Dewhurst Philip 
Published: September 2023

ABSTRACT

Objective
To investigate if chiropractic placement students in the United Kingdom are aware of current pain evidence and how they relate this to the management of chronic pain patients. Moreover, to gain an understanding of how this can lead to improved pain education planning and engagement in the future.

Methods
The revised Neurophysiology of Pain Questionnaire and the researchers' own questionnaire were administered online to chiropractic placement students. The aggregated total number of correct responses and the individual mean scores were calculated. Statistical analysis included tests of normality and difference using the Kolmogorov-Smirnov, Mann-Whitney U, Kruskal-Wallis, and Χ2 tests.

Results
There was an overall response rate of 21.6% (n = 50). The mean score achieved on the revised neurophysiology of pain questionnaire was 37.8%. A significant difference between individual mean scores on the revised Neurophysiology of Pain Questionnaire was observed between male and female participants. No differences in mean score were observed between age, number of chronic pain patients seen, and previous qualifications. For the study-specific questionnaire, statistically significant differences were found in mean score for previous qualifications, number of patients seen, and sex.

Conclusion
Chiropractic placement students in the United Kingdom appear to have a lower level of pain knowledge than other health care professionals and education institutions may wish to consider how to best address this within their curricula.
Keeping It Real: Practice Relevant Education. Chiropractic Educators Research Forum (CERF), June 24, 2023
Authors:   Chiropractic Educators Research Forum
Published: September 2023

ABSTRACT
This conference was convened by the Chiropractic Educators Research Forum (CERF) on June 24, 2023. This meeting provided a forum for the presentation of scholarly works in education theory and practice. This conference specifically focused on research related to developing competency in practice-relevant skills, knowledge, and attitudes. As educators, we help our students develop their cognitive, psychomotor, and affective abilities. Throughout this process, we must keep in mind what we are producing: health care providers. Our graduates must demonstrate competency in relevant knowledge, skills, and attitudes to practicing health care in a professional and evidence-based manner (ie, intersection of best evidence, clinical expertise, and patient values). Therefore, integrating practice-relevant skills, knowledge, and attitudes is essential throughout our programs. During the June 2023 CERF meeting, presenters and panelists took an in-depth look at education research and how chiropractic programs work to deliver practice-relevant education.

Published: September 2023

The method based on the description of the probabilities of states using a non-stationary Poisson flow allows using elementary reasoning to find not only a stationary, but also a non-stationary distribution of the number of requirements in the system.
To find a stationary distribution of the number of requirements in queuing systems (QS), the method of introducing additional variables leading to a piecewise linear Markov process is used.
The fact of invariance is shown: the stationary probabilities of pi states in queuing systems (QS) M/G/n/0 depend only on the average service time of the requirement and do not depend on the type of distribution G(x).

Full Recovery without Complications by Early Intervention for Malignant Hyperthermia that Occurred during General Anaesthesia: A Case Series of Two Infants with Facial Anomaly
Authors: Lee Jae Eun , Choi Hyoun Ho , Won Young Ju , Lim Byung Gun 
Published: September 2023

Introduction: Malignant hyperthermia (MH) is a rare and life-threatening condition characterized by muscle rigidity, hypermetabolism, and other symptoms triggered by certain anaesthetic agents. It is linked to abnormal calcium release in skeletal muscles, often associated with genetic susceptibility or musculoskeletal disorders like scoliosis. Early recognition of MH symptoms, including muscle rigidity, tachycardia, and acidosis, is crucial for prompt intervention. Here, we report two infants with successful recovery following early MH intervention during general anaesthesia.
Case Report 1: A 26-month-old male with cleft hard palate, prematurity history, and chromosomal anomaly underwent palatoplasty. Anesthesia was induced with thiopental, fentanyl, and rocuronium, followed by sevoflurane/remifentanil maintenance. During surgery, the heart rate increased suddenly with hypercapnia. Hyperthermia of 39.5°C, suggestive of MH, arose. Sevoflurane was discontinued, cooling measures were initiated, and dantrolene was administered 2 hours later. Temperature normalized, ventilation improved, and extubation succeeded. Creatine phosphokinase (CPK) level was briefly elevated to 1062 IU/L but returned to normal. Despite being suspected of having MH, the patient was discharged without any complications after one day of intensive care unit (ICU) care.
Case Report 2: A 5-month-old female with cleft lip underwent cleft lip repair surgery. She had underlying congenital heart diseases. During anaesthesia, sudden hypercapnia and hyperthermia indicated potential MH. Sevoflurane was discontinued, and ketamine, and fentanyl were used to maintain anaesthesia. Dantrolene was administered after 80 min, cooling the patient and stabilizing the hypercapnia. The surgery ended 110 min after the sudden hyperthermia. In the ICU, metabolic acidosis was managed with sodium bicarbonate. Postoperative muscle enzyme, such as CPK, levels slightly rose, then normalized. Stable recovery led to discharge after 8 days without complications.
Conclusion: In both cases, MH occurred in infants with facial anomalies and early interventions, such as dantrolene administration, for suspected MH was done. Early suspicion, supported by diagnostic tools like the MH Clinical Grading Scale, is vital.

ImportanceCollaborative dementia care programs are effective in addressing the needs of patients with dementia and their caregivers. However, attempts to consider effects on health care spending have been limited, leaving a critical gap in the conversation around value-based dementia care.ObjectiveTo determine the effect of participation in collaborative dementia care on total Medicare reimbursement costs compared with usual care.Design, Setting, and ParticipantsThis was a prespecified secondary analysis of the Care Ecosystem trial, a 12-month, single-blind, parallel-group randomized clinical trial conducted from March 2015 to March 2018 at 2 academic medical centers in California and Nebraska. Participants were patients with dementia who were living in the community, aged 45 years or older, and had a primary caregiver and Medicare fee-for-service coverage for the duration of the trial.InterventionTelehealth dementia care program that entailed assignment to an unlicensed dementia care guide who provided caregiver support, standardized education, and connection to licensed dementia care specialists.Main Outcomes and MeasuresPrimary outcome was the sum of all Medicare claim payments during study enrollment, excluding Part D (drugs).ResultsOf the 780 patients in the Care Ecosystem trial, 460 (59.0%) were eligible for and included in this analysis. Patients had a median (IQR) age of 78 (72-84) years, and 256 (55.7%) identified as female. Participation in collaborative dementia care reduced the total cost of care by $3290 from 1 to 6 months postenrollment (95% CI, −$6149 to −$431; P = .02) and by $3027 from 7 to 12 months postenrollment (95% CI, −$5899 to −$154; P = .04), corresponding overall to a mean monthly cost reduction of $526 across 12 months. An evaluation of baseline predictors of greater cost reduction identified trends for recent emergency department visit (−$5944; 95% CI, −$10 336 to −$1553; interaction P = .07) and caregiver depression (−$6556; 95% CI, −$11 059 to −$2052; interaction P = .05).Conclusions and RelevanceIn this secondary analysis of a randomized clinical trial among Medicare beneficiaries with dementia, the Care Ecosystem model was associated with lower total cost of care compared with usual care. Collaborative dementia care programs are a cost-effective, high-value model for dementia care.Trial RegistrationClinicalTrials.gov Identifier: NCT02213458

AbstractBimetallic composites exhibit great potential as anode materials in advanced energy storage systems owing to their inherent tunability, cost‐effectiveness, and simultaneous achievement of high specific capacity and low reaction potential. However, simple biphase mixing often fails to achieve satisfactory performance. Herein, an innovative stress self‐adaptive bimetallic stellar nanosphere (50–200 nm) wherein bismuth (Bi) is fabricated, as a core, is seamlessly encapsulated by a tin (Sn) sneath (Sn‐Bi@C). This well‐integrated stellar configuration with bimetallic nature embodies the synergy between Bi and Sn, offering fortified conductivity and heightened sodium ion diffusion kinetics. Moreover, through meticulous utilization of finite element analysis simulations, a homogeneous stress distribution within the Sn‐enveloped Bi, efficiently mitigating the structural strain raised from the insertion of Na+ ions, is uncovered. The corresponding electrode demonstrates remarkable cyclic stability, as it exhibits no capacity decay after 100 cycles at 0.1 A g−1. Furthermore, it achieves an impressive 86.9% capacity retention even after an extensive 2000 cycles. When employed in a Na3V2(PO4)3 ‖ Sn‐Bi@C full cell configuration, it demonstrates exceptional capacity retention of 97.06% after 300 cycles at 1 A g−1, along with a high energy density of 251.2 W h kg−1.

Published: September 2023

AbstractMicroporous annealed particle (MAP) scaffolds are injectable granular materials comprised of micron sized hydrogel particles (microgels). The diameter of these microgels directly determines the size of the interconnected void space between particles where infiltrating or encapsulated cells reside. This tunable porosity allows the authors to use MAP scaffolds to study the impact of spatial confinement (SC) on both cellular behaviors and the host response to biomaterials. Despite previous studies showing that pore size and SC influence cellular phenotypes, including mitigating macrophage inflammatory response, there is still a gap in knowledge regarding how SC within a biomaterial modulates immune cell recruitment in vivo in wounds and implants. Thus, the immune cell profile within confined and unconfined biomaterials is studied using small (40 µm), medium (70 µm), and large (130 µm) diameter spherical microgels, respectively. This work uncovered that MAP scaffolds impart regenerative wound healing with an IgG1‐biased Th2 response. MAP scaffolds made with large microgels promote a balanced pro‐regenerative macrophage response, resulting in enhanced wound healing with mature collagen regeneration and reduced inflammation levels.

AbstractTitanium selenide (TiSe2), a model transition metal chalcogenide material, typically relies on topotactic ion intercalation/deintercalation to achieve stable ion storage with minimal disruption of the transport pathways but has restricted capacity (<130 mAh g−1). Developing novel energy storage mechanisms beyond conventional intercalation to break capacity limits in TiSe2 cathodes is essential yet challenging. Herein, the ion storage properties of TiSe2 are revisited and an unusual thermodynamically stable twin topotactic/nontopotactic Cu2+ accommodation mechanism for aqueous batteries is unraveled. In situ synchrotron X‐ray diffraction and ex situ microscopy jointly demonstrated that topotactic intercalation sustained the ion transport framework, nontopotactic conversion involved localized multielectron reactions, and these two parallel reactions are miraculously intertwined in nanoscale space. Comprehensive experimental and theoretical results suggested that the twin‐reaction mechanism significantly improved the electron transfer ability, and the reserved intercalated TiSe2 structure anchored the reduced titanium monomers with high affinity and promoted efficient charge transfer to synergistically enhance the capacity and reversibility. Consequently, TiSe2 nanoflake cathodes delivered a never‐before‐achieved capacity of 275.9 mAh g−1 at 0.1 A g−1, 93.5% capacity retention over 1000 cycles, and endow hybrid batteries (TiSe2‐Cu||Zn) with a stable energy supply of 181.34 Wh kg−1 at 2339.81 W kg−1, offering a promising model for aqueous ion storage.
Crystal Engineering of Silica Anode Achieving Intrinsic Zero‐Strain
Authors: Wang Fei , Mao Jian , Zhao Yan 
Published: September 2023

AbstractSi‐based anodes have large intrinsic volume expansion, which hinders their practicality and commercialization. To address this challenge, the design principle of intrinsic zero‐strain anodes (① large intracrystalline cavities and ② strong bonds) is proposed, and silica with large intracrystalline cavities (SLIC) established by strong Si─O bonds ([SiO4] coordinate structures) is obtained and acts as an anode, achieving the intrinsic zero‐strain feature first in silicon‐based anodes. The phase structure of SLIC is maintained and the [SiO4] coordinate structure merely shows slight disorder during cycling. The feature stems from lithiation taking place by the solid‐solution insertion reaction rather than the conventional conversion/alloying addition reactions, because the solid‐solution insertion reaction for the SLIC has the lowest change in the Gibbs free energy. The SLIC anode demonstrates excellent cycling stability and high initial Coulombic efficiency (≈85%). Moreover, owing to the low working voltage (≈0.28 V) and relatively high specific capacity, the SLIC anode presents the highest gravimetric energy density among reported zero‐/quasi‐zero‐strain anodes and high volumetric energy density (around twice as much as graphite). The universality of the designing principle is also validated. This work provides design guidelines for zero‐strain anodes in next‐generation batteries.
