This study investigates the functionality and feasibility of a novel smart seat cushion system designed for wheelchair users with spinal cord injuries. The cushion, equipped with air cells that serve as both sensors and actuators, was tested on 24 participants for its real-time pressure mapping, automated pressure redistribution, and pressure offloading functions. A commercial pressure mat was concurrently used to validate the cushion's pressure modulation functions. Additionally, the perceived comfort of the cushion was evaluated using General Discomfort Assessment (GDA) and Discomfort Intensity (DIS) scores, which provided insights into participants' overall comfort and discomfort levels. Real-time pressure profiles generated by the cushion resembled commercial pressure mat readings. During tests with individuals with spinal cord injury, the cushion was able to dynamically generate and display the real-time pressure profile of a seated individual with strong precision (correlation to commercial pressure mat: r ranging from 0.76 to 0.88), providing effective input into pressure modulation functions. Pressure redistribution algorithms eliminated peak pressure and reduced the overall pressure at the interface. Pressure offloading algorithms automatically identified the regions with the highest interface pressure and subsequently relieved the pressure from those areas. User feedback showed that the cushion was comfortable after redistribution and offloading. This work demonstrated the feasibility of an advanced smart seat cushion system for wheelchair users with spinal cord injuries. The cushion was capable of redistributing pressure evenly across the seating surface, ensuring user's comfort. Additionally, it identifies and eliminates high-pressure points, further improving comfort and reducing the risk of pressure injuries. IMPLICATIONS FOR REHABILITATION: Majority of wheelchair users acquire pressure injuries in their lifetime, where the magnitude and duration of sitting interface pressure are major contributing factors to develop pressure injuries. Compliant cushions and frequent weight shifting can reduce the magnitude and duration of sitting interface pressure; however, the long-term effectiveness of these cushions and the user's lack of compliance to the weight shifting protocols impact their efficacy drastically. An automated cushion system that can reduce the magnitude of the pressure based on the user's current pressure profile and offload pressure from vulnerable areas would improve the effectiveness of the cushion and compensate for poor adherence to weight shifting protocols. Automated solutions will significantly improve the quality of care provided to wheelchair users and reduce the risk of developing pressure injuries. [ABSTRACT FROM AUTHOR]

After spinal cord injury (SCI), inpatient rehabilitation begins and continues through outpatient therapy. Overground exoskeleton gait training (OEGT) has been shown to be feasible in both settings, yet its use as an intervention across the continuum has not yet been reported. This study describes OEGT for patients with SCI across the continuum and its effects on clinical outcomes. Medical records of patients with SCI who completed at least one OEGT session during inpatient and outpatient rehabilitation from 2018 to 2021 were retrospectively reviewed. Demographic data, Walking Index for Spinal Cord Injury-II (WISCI-II) scores, and OEGT session details (frequency, "walk" time, "up" time, and step count) were extracted. Eighteen patients [male (83%), White (61%), aged 37.4 ± 15 years, with tetraplegia (50%), American Spinal Injury Association Impairment Scale A (28%), B (22%), C (39%), D (11%)] completed OEGT sessions (motor complete, 18.2 ± 10.3; motor incomplete, 16.7 ± 7.7) over approximately 18 weeks (motor complete, 15.1 ± 6.4; motor incomplete, 19.0 ± 8.2). Patients demonstrated improved OEGT session tolerance on device metrics including "walk" time (motor complete, 7:51 ± 4:42 to 24:50 ± 9:35 minutes; motor incomplete, 12:16 ± 6:01 to 20:01 ± 08:05 minutes), "up" time (motor complete, 16:03 ± 7:41 to 29:49 ± 12:44 minutes; motor incomplete, 16:38 ± 4:51 to 23:06 ± 08:50 minutes), and step count (motor complete, 340 ± 295.9 to 840.2 ± 379.4; motor incomplete, 372.3 ± 225.2 to 713.2 ± 272). Across therapy settings, patients with motor complete SCI experienced improvement in WISCI-II scores from 0 ± 0 at inpatient admission to 3 ± 4.6 by outpatient discharge, whereas the motor incomplete group demonstrated a change of 0.2 ± 0.4 to 9.0 ± 6.4. Patients completed OEGT across the therapy continuum. Patients with motor incomplete SCI experienced clinically meaningful improvements in walking function. [ABSTRACT FROM AUTHOR]

Objective: Learning to walk is a major goal of inpatient rehabilitation and robotic exoskeletons may provide a new gait training approach. Our purpose was to determine the feasibility of integrating the Ekso Gait Training device into inpatient rehabilitation in a neurologic population. Design: Longitudinal cohort design and convenience sample including physical therapists trained to use the Ekso Bionics Ekso GT™ robotic exoskeleton or inpatients with stroke or SCI. Therapists completed a focus group and survey at baseline and 6 months after initial Ekso training. Patients completed a survey indicating their satisfaction with using the Ekso. Results: Twenty-five patients used the Ekso an average of 4.5 sessions during their 38.5-day rehabilitation stay. Survey and focus group feedback revealed that therapists encountered measurement difficulties with the Ekso and limited treatment time influencing effectiveness of usage. After 6 months, therapists reported an improvement in feasibility. Patients tolerated Ekso sessions well, without any complications or adverse incidents, and reported improved mobility post session. Conclusion: Integrating Ekso gait training into clinical practice was not seamless but appears feasible. Barriers were addressed within the rehabilitation team and received administrative support in a process lasting several months. Patients enjoyed walking in Ekso and felt secure within the device. Integrating Ekso gait training into clinical practice during inpatient rehabilitation is feasible. Overcoming barriers to implementation required administrative support and clinician persistence over several months. Patients tolerated Ekso sessions well, without any complications or adverse incidents. [ABSTRACT FROM AUTHOR]

Background: Human papillomavirus (HPV) and p53 alterations are speculated to play a role in carcinogenesis. This study was carried out to find out the association of HPV and p53 with precancerous lesions of the oral cavity such as leukoplakia: The objective of this study was to find the association among human papilloma virus (HPV) 16 infections and p53 polymorphism in tobacco using the oral leukoplakia patients. Methods: A total of 91 oral leukoplakia patients and 100 controls were randomly selected from the out-patient department of a tertiary care dental hospital of North-east India. Blood samples were drawn incisional biopsy was performed from the lesion proper and the tissue was processed for histopathological grading. Cytological smears were taken from the lesional site of leukoplakia patients and buccal mucosa of controls. The rate of HPV infection and p53 polymorphism was detected with the help of polymerase chain reaction, gel electrophoresis and deoxyribonucleic acid sequencing. Results: The rate of HPV 16 infection was found significantly high in the oral leukoplakia patients. No particular p53 genotype at exon 4 of codon 72 was found to be associated with oral leukoplakia, but "C" allele (proline) at exon 4 of codon 72 was significantly raised in these patients. Conclusions: Oral leukoplakia, a well-known pre-cancerous lesion, has been shown to be associated with tobacco, but certain other factors like HPV infection and p53 polymorphism may play an important role in its development.

Peripheral ossifying fibroma (POF) is a reactive gingival lesion exhibiting a diverse spectrum of histopathology, accounting for 9.6% of gingival lesions. This study encompasses a detailed clinical, radiographic, and histopathological analysis of 15 cases of POF, retrieved from departmental archives. The following cases were subsequently stained with a histochemical stain (van Gieson) and observed under a polarizing microscope. This study is an effort to analyze the diverse spectrum of mineralized components and their surrounding tissues. Clinically, the study revealed a female predilection (73%) with the second and third decade commonly affected. The most common site was interdental papilla of anterior region, presenting itself as pink and sessile nodular mass. Radiographic examination revealed 93% of the cases showing no manifestation on the radiograph. Histopathological analysis showed 73% of the cases exhibited a fibrocellular connective tissue stroma with plump fibroblasts around the mineralized areas. The collagen was predominantly mature. Polarizing microscopy of the mineralized tissue revealed that 53% of the cases showed only woven bone, 20% showed combination of lamellar bone and cellular cementum, 13.3% showed only cementum (cellular and acellular) with another 13.3% showing mixture of woven and lamellar bone. Thus, the concept/theory that POF develops from cells of PDL/periosteum is emphasized. The undifferentiated mesenchymal cells have an inherent proliferative potential and can form bone or cementum, whose nature can be confirmed by polarizing microscope. This origin from periodontal ligament can also account for the high recurrence rate seen in POF. [ABSTRACT FROM AUTHOR]

Aggressive fibromatosis is a comparitively rare tumor with unpredictable growth and varying local recurrence rates. It does not develop distant metastases but locally it shows an aggressive and infiltrative behavior. Clinically, aggressive fibromatosis manifests as a painless, firm, often rapidly enlarging mass, fixed to underlying bone or soft tissue. It is never encapsulated. Histologically, it is rich in collagen and fibroblastic cells that are devoid of hyperchromatic or atypical nuclei, but with more variable cellularity in different tumor sections.

Purpose/objective: Individuals with a spinal cord injury (SCI) may experience posttraumatic stress disorder (PTSD) at a higher rate, which is associated with worse psychiatric comorbidity, decreased quality of life, and greater disability. Yet, effective PTSD interventions remain understudied for individuals with SCI. We conducted the first randomized controlled trial (RCT) of an evidence-based psychotherapy (prolonged exposure [PE]) with survivors of SCI during acute rehabilitation. We examined the efficacy, feasibility, and secondary outcomes., Research Method/design: Participants ( n = 29) were adults recruited from 2018 to 2021 1-month postinjury with PTSD randomized into either PE therapy or treatment as usual. The primary outcome was PTSD assessed at baseline, 6, 10, and 32 weeks postenrollment., Results: An overall group-by-time interaction was not statistically significant ( p = .102), but effect sizes demonstrated moderate and large improvements in PTSD for the PE group at 6 (-19.4 vs. -9.7) and 10 (-25.8 vs. -5.7), respectively. Similarly, moderate to large effect sizes were observed for depression, maladaptive posttraumatic cognitions, disruptive nocturnal behaviors, SCI-related quality of life, and risky alcohol consumption. Low rates of enrollment (50%) and treatment completion (25%) suggest feasibility challenges; however, treatment completers did report high satisfaction (100%)., Conclusions/implications: Results suggest that individuals who received PE had a quicker and clinically meaningful reduction in PTSD symptoms, but delivery during acute rehabilitation is not feasible for many individuals. Future research should examine abbreviated versions of PE for PTSD to enhance the feasibility of treatment in this setting. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
