BACKGROUND AND OBJECTIVES

Telerehabilitation is the remote delivery of rehabilitation services using telecommunication technologies. Its local adoption was catalyzed by the COVID-19 pandemic, prompting the need to assess user acceptance. This study aimed to determine the acceptance of stroke telerehabilitation among patients, carers, and rehabilitation providers in the Department of Physical Medicine and Rehabilitation at St. Luke’s Medical Center – Global City and Quezon City.

METHODS

This descriptive cross-sectional study used purposive sampling to recruit 73 rehabilitation providers and 10 consumers. Data were collected using a self-administered survey based on the Technology Acceptance Model, covering perceived ease of use, usefulness, and behavioral intent. Descriptive and inferential statistics were used for analysis.

RESULTS

Most providers (94.4%) were familiar with telerehabilitation, while only half of the consumers were aware of it. Acceptance was moderate among providers (mean score: 35.75 ± 8.67) and high among consumers (mean score: 31.6 ± 7.52). Female providers were less likely to accept telerehabilitation (p=0.049). Consumers identified financial constraints and lack of a companion as key barriers, while providers cited internet issues and technology use. Both groups viewed telerehabilitation positively for teleconsultation, teletherapy, and telemonitoring. Smartphones were the preferred device; Viber and Facebook Messenger were the most commonly chosen platforms.

CONCLUSION

Stroke telerehabilitation was moderately to highly accepted by rehabilitation stakeholders in two tertiary private hospitals in Manila. Findings may guide institutional planning for telerehabilitation services. Training, infrastructure support, and awareness campaigns can help address implementation barriers.

BACKGROUND

Occupational burnout is a growing concern in healthcare, which affects professionals across various disciplines. Radiographers working in non-traditional practice settings may face unique stressors that contribute to burnout, yet this population remains understudied, particularly in the Philippines.

OBJECTIVES

This study aimed to (1) assess and compare burnout levels among Filipino radiographers in non-traditional roles, (2) investigate the relationship between demographic variables and burnout, and (3) assess burnout severity by imaging role.

METHODS

A cross-sectional, quantitative survey design was employed. Participants (n = 188) completed an online survey including demographic questions and the Maslach Burnout Inventory (MBI). Data analysis was performed using SPSS 23. Non-parametric tests were used to assess relationships between demographic variables and MBI scores.

RESULTS

Significant differences in burnout scores were found across imaging roles (p = .000). Mobile imaging professionals reported the highest emotional exhaustion (M = 48.4, SD = 4.7) and depersonalization (M = 21.5, SD = 4.7), and the lowest personal accomplishment (M = 18.1, SD = 7.2). Forensic imaging professionals reported the lowest overall burnout (M = 58.9, SD = 13.8) and depersonalization (M = 7.7, SD = 4.3), and the highest personal accomplishment (M = 29.4, SD = 8.3). Sex differences were observed for depersonalization (p = .045), with males scoring higher. Participants with graduate degrees reported lower personal accomplishment (p = .036). Severe burnout was the dominant category, especially in mobile, military, and veterinary imaging.

CONCLUSION

Burnout levels vary significantly among Filipino radiographers in non-traditional roles, with mobile imaging professionals at particularly high risk. These findings highlight the need for targeted interventions to mitigate burnout and promote wellbeing in this population.

BACKGROUND

Stroke is a leading cause of morbidity and mortality in the Philippines. Telestroke systems have been introduced to improve timely recognition and referral; however, their effectiveness depends on utilization at the community level.

OBJECTIVE

To assess stroke and telestroke knowledge, attitudes, practices, and barriers among barangay health workers (BHWs), and to determine factors associated with telestroke utilization.

METHODS

A cross-sectional study was conducted among 202 BHWs. Data were collected using a structured questionnaire assessing knowledge, attitudes, practices, and perceived barriers. Descriptive statistics were used to summarize responses. Associations between variables were analyzed using appropriate statistical tests, with significance set at p < 0.05.

RESULTS

Respondents had high stroke knowledge (75.5%, SD = 17.45) and telestroke knowledge (85.5%, SD = 18.82), as well as favorable attitudes (mean = 4.37). However, only 31.1% reported telestroke utilization. The most commonly reported barriers were lack of training (61.4%) and poor internet connectivity (15.8%). Telestroke familiarity was significantly associated with higher knowledge (p = 0.005) and more favorable attitudes (p = 0.001). Stroke-related training (p = 0.001) and years of experience (p = 0.001) were significantly associated with higher utilization.

CONCLUSION

Despite high knowledge and favorable attitudes, telestroke utilization among BHWs remains low. Training, familiarity, and infrastructure appear to play key roles in bridging the gap between knowledge and practice. Strengthening these factors may improve the effectiveness of community-based telestroke systems.

BACKGROUND

Diabetes mellitus (DM) remains a major global health burden, with increasing prevalence in developing countries such as the Philippines. Accuracy of glucose measurement is vital for diagnosis and management; however, preanalytical variables, particularly glycolysis from varying collection tubes, temperature and time interval can significantly affect test results. Despite guideline recommendations favoring plasma, serum is still commonly used in local clinical practice.

OBJECTIVE

This study evaluated the effectiveness of different commercially available blood collection tubes in preserving glucose stability by minimizing pre-analytical glycolysis.

METHODOLOGY

A cross-sectional observational and quasi-experimental study was conducted among 40 healthy adult participants (18–59 years) from a tertiary institution in Quezon City, Philippines. A total of 160 samples were collected using four tube types (one plasma and three serum tubes). Samples were analyzed at varying time intervals (0–180 minutes) and storage conditions (room temperature and 4°C). Glucose levels were measured using the glucose oxidase method. Statistical analysis included Shapiro–Wilk, Kruskal–Wallis H-test, Welch’s t-test, and Dwass–Steel–Critchlow–Fligner post hoc comparisons at a 1% significance level.

RESULTS

Glucose concentrations differed significantly across tube types (pCONCLUSION

Blood collection tube type and delayed processing significantly influence glucose measurements. While acceptable within analytical limits, systematic biases may affect clinical interpretation. Standardization of blood collection practices and stricter pre-analytical protocols are essential to improve diagnostic accuracy for diabetes in the Philippines.

BACKGROUND AND OBJECTIVES

The COVID-19 pandemic forced academic institutions to suspend face-to-face activities, causing a drastic shift to a remote and online setting for learning and teaching. While necessary, the sudden change created a lasting effect on the constituents of medical schools whose curriculum relied on lectures, clinical skills, and hospital experience in teaching its students. This study aims to describe the effect of the rapid digitalization on the medical faculty at the St. Luke’s Medical Center College of Medicine-William H. Quasha Memorial (SLMCCM) in Metro Manila, Philippines.

METHODS

Members of the medical faculty of the college were invited to participate in focus group discussions (FGDs) where four frames were discussed, namely content, pedagogy, technology, and mindset. Responses taken in the FGDs underwent thematic analysis to find commonalities and patterns among the concerns and comments of the faculty.

RESULTS

Analysis of faculty feedback regarding the four frames revealed a spectrum of responses, encompassing both positive and negative sentiments. Content-related feedback predominantly focused on strategies for effectively segmenting and synthesizing information within the online environment. Pedagogical concerns are primarily centered on adapting teaching methods and delivery styles to the online format. Technological feedback highlighted the perceived advantages and limitations of online platforms and tools, as well as the role of technological support in facilitating the transition to online instruction. Finally, a significant portion of the feedback addressed the psychological effects of the pandemic on faculty members as medical educators, with responses ranging from expressions of fear to statements of confidence.

CONCLUSION

In the context of the evolving educational landscape, particularly the accelerated adoption of online and hybrid learning models in medical education, faculty recognition of the necessity of digitalization is paramount. Despite the inherent challenges of this transition, the faculty's demonstrated openness to change and innovation presents a significant opportunity for institutional growth. By continuing to invest in these technologies, institutions can not only enhance the medical curriculum but also prepare future physicians for the increasingly digital nature of healthcare delivery.

Pulpitis is a common infective oral disease in clinical situations. The regulatory mechanisms of immune defense in pulpitis are still being investigated. Osteomodulin (OMD) is a small leucine-rich proteoglycan family member distributed in bones and teeth. It is a bioactive protein that promotes osteogenesis and suppresses the apoptosis of human dental pulp stem cells (hDPSCs). In this study, the role of OMD in pulpitis and the OMD-induced regulatory mechanism were investigated. The OMD expression in normal and inflamed human pulp tissues was detected via immunofluorescence staining. Intriguingly, the OMD expression decreased in the inflammatory infiltration area of pulpitis specimens. The cellular experiments demonstrated that recombined human OMD could resist the detrimental effects of lipopolysaccharide (LPS)-induced inflammation. A conditional Omd knockout mouse model with pulpal inflammation was established. LPS-induced inflammatory impairment significantly increased in conditional Omd knockout mice, whereas OMD administration exhibited a protective effect against pulpitis. Mechanistically, the transcriptome alterations of OMD overexpression showed significant enrichment in the nuclear factor-κB (NF-κB) signaling pathway. Interleukin-1 receptor 1 (IL1R1), a vital membrane receptor activating the NF-κB pathway, was significantly downregulated in OMD-overexpressing hDPSCs. Additionally, the interaction between OMD and IL1R1 was verified using co-immunoprecipitation and molecular docking. In vivo, excessive pulpal inflammation in Omd-deficient mice was rescued using an IL1R antagonist. Overall, OMD played a protective role in the inflammatory response via the IL1R1/NF-κB signaling pathway. OMD may optimize the immunomodulatory functions of hDPSCs and can be used for regenerative endodontics.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Tooth pulpitis is a prevalent oral disorder. Understanding the underlying mechanisms of pulpitis and developing effective treatment strategies hold great significance. Ferroptosis has recently emerged as a new form of cell death, but the role of ferroptosis in pulpitis remains largely unknown. In our study, single-cell RNA sequencing (scRNA-seq) was used to identify cellular heterogeneity between 3 pulpitis tissue and 3 healthy pulp tissue, and explored ferroptosis occurrence in pulpitis tissue and inflamed dental pulp cells (DPCs). In scRNA-seq, 40 231 cells (Pulpitis: 17 814; Healthy pulp: 22 417) were captured, and visualized into 12 distinct cell clusters. Differentially expressed ferroptosis-related genes (DE-FRGs) were almost presented in each cluster in pulpitis vs healthy pulp. ROS and Fe²⁺ levels significantly rose, and immunohistochemistry showed low expression of GPX4 and high expression of PTGS2 in pulpitis. In LPS-stimulated DPCs, thymosin α1 increased the expression of GPX4 and FTL, and decreased expression of TNF-α, IL-1β, IL-6, and Fe²⁺ levels. In rat pulpitis models, both prothymosin α (PTMA, precursor of thymosin α1) gelatin sponge placed at the hole of pulp (LPS-P(gs)) and PTMA injection in pulp (LPS-P(i)) significantly reduced infiltration of inflammatory cells and expression of PTGS2, and increased the expression of GPX4. In RNA sequencing, the expression of DE-FRGs were reversed when thymosin α1 were added in LPS-stimulated DPCs. Collectively, single-cell atlas reveals cellular heterogeneity between pulpitis and healthy pulp, and ferroptosis occurrence in pulpitis. Thymosin α1 may reduce ferroptosis in DPCs to alleviate pulpitis and thus potentially has the ability to treat pulpitis.

OBJECTIVES: This study aims to use 3D prin-ting technology based on the principle of stereo lithography apparatus (SLA) to shape dental lithium disilicate ceramics and study the effects of different slurry proportions on the microstructure and properties of heat-treated samples. METHODS: The experimental group comprised lithium disilicate ceramics manufactured through SLA 3D printing, and the control group comprised lithium disilicate ceramics (IPS e.max CAD) fabricated through commercial milling. An array of different particle sizes of lithium disilicate ceramic powder materials (nano and micron) was selected for mixing with photocurable acrylate resin. The proportion of experimental raw materials was adjusted to prepare five groups of ceramic slurries for 3D printing (Groups S1-S5) on the basis of rheological properties, stability, and other factors. Printing, debonding, and sintering were conducted on the experimental group with the optimal ratio, followed by measurements of microstructure, crystallographic information, shrinkage, and mechanical properties. RESULTS: Five groups of lithium disilicate ceramic slurries were prepared, of which two groups with high solid content (75%) (Groups S2 and S3) were selected for 3D printing. X-ray diffraction and scanning electron microscopy results showed that lithium disilicate was the main crystalline phase in Groups S2 and S3, and its microstructure was slender, uniform, and compact. The average grain sizes of Groups S2 and S3 were (559.79±84.58) nm and (388.26±61.49) nm, respectively (P<0.05). Energy spectroscopy revealed that the samples in the two groups contained a high proportion of Si and O elements. After heat treatment, the shrinkage rate of the two groups of ceramic samples was 18.00%-20.71%. Test results revealed no statistical difference in all mechanical properties between Groups S2 and S3 (P>0.05). The flexural strengths of Groups S2 and S3 were (231.79±21.71) MPa and (214.86±46.64) MPa, respectively, which were lower than that of the IPS e.max CAD group (P<0.05). The elasticity modulus of Groups S2 and S3 were (87.40±12.99) GPa and (92.87±19.76) GPa, respectively, which did not significantly differ from that of the IPS e.max CAD group (P>0.05). The Vickers hardness values of Groups S2 and S3 were (6.53±0.19) GPa and (6.25±0.12) GPa, respectively, which were higher than that of the IPS e.max CAD group (P<0.05). The fracture toughness values of Groups S2 and S3 were (1.57±0.28) MPa·m^0.5 and (1.38±0.17) MPa·m^0.5, respectively, which did not significantly differ from that of the IPS e.max CAD group (P>0.05). CONCLUSIONS The combination of lithium disilicate ceramic powders with different particle sizes can yield a slurry with high solid content (75%) and suitable viscosity and stability. The dental lithium disilicate ceramic material is successfully prepared by using 3D printing technology. The 3D-printed samples show a small shrinkage rate after heat treatment. Their microstructure conforms to the crystal phase of lithium disilicate ceramics, and their mechanical properties are close to those of milled lithium disilicate ceramics.

OBJECTIVES: This study aimed to evaluate the repeatability and reliability of a self-developed domestic wireless surface electromyography (sEMG) system (Oralmetry) in assessing the activity of the temporalis and masseter muscles to provide theoretical support for its clinical application. METHODS: Twenty-two volunteers were recruited. Through multiple repeated measurements, the sEMG signals of bilateral anterior temporalis and masseter muscles during maximum voluntary clenching were collected using the self-developed sEMG device, Oralmetry, and two commercial sEMG devices (Zebris and Teethan), filtered, screened, and standardized. Seven sEMG indicators for assessing masticatory muscle function were calculated. The intraclass correlation coefficient (ICC) was used to evaluate the repeatability of the measurements from the three sEMG devices, and statistical analysis was conducted to compare the consistency of the seven sEMG indicators obtained from the devices. RESULTS: Among the 22 participants, the ICC values of the repeated measurements from the three sEMG devices ranged from 0.88 to 0.99. The measurements of three sEMG indicators (antero-posterior coeffificient, percentage overlapping coeffificient_MM, and percentage overlapping coeffificient_TA) obtained by Zebris were significantly different from those obtained by Oralmetry and Teethan (P<0.05). No significant differences in the measurements of the seven sEMG indicators were found between Oralmetry and Teethan. CONCLUSIONS Oralmetry and the two commercial sEMG devices demonstrated good repeatability in capturing sEMG indicators for evaluating masticatory muscle function. In particular, Oralmetry showed the highest ICC values. All three devices also exhibited good consistency in measuring sEMG indicators, and a high agreement was observed between the two wireless sEMG devices (Oralmetry and Teethan). These findings provide theoretical support for the clinical application of Oralmetry.
