BACKGROUND: Priming strategies that improve the functionality of MSCs may be required to address issues limiting successful clinical translation of MSC therapies. For conditions requiring high trophic support such as brain and spinal cord injuries, priming MSCs to produce higher levels of trophic factors may be instrumental to facilitate translation of current MSC therapies. We developed and tested a novel molecular priming paradigm using docosahexaenoic acid (DHA) to prime adipose tissue-derived mesenchymal stromal cells (ASCs) to enhance the secretome neuroregulatory potential. METHODS: Comprehensive dose–response and time-course assays were carried to determine an optimal priming protocol. Secretome total protein measurements were taken in association with cell viability, density and morphometric assessments. Cell identity and differentiation capacity were studied by flow cytometry and lineage-specific markers. Cell growth was assessed by trypan-blue exclusion and senescence was probed over time using SA-b-gal, morphometry and gene expression. Secretomes were tested for their ability to support differentiation and neurite outgrowth of human neural progenitor cells (hNPCs). Neuroregulatory proteins in the secretome were identified using multiplex membrane arrays. RESULTS: Priming with 40 lM DHA for 72 h significantly enhanced the biosynthetic capacity of ASCs, producing a secretome with higher protein levels and increased metabolic viability. DHA priming enhanced ASCs adipogenic differentiation and adapted their responses to replicative senescence induction. Furthermore, priming increased concentrations of neurotrophic factors in the secretome promoting neurite outgrowth and modulating the differentiation of hNPCs. CONCLUSIONS These results provide proof-of-concept evidence that DHA priming is a viable strategy to improve the neuroregulatory profile of ASCs.

BACKGROUND

To compare biomechanical strength of the Pulvertaft (PT) weave and the side-to-side (STS) tendon repair techniques.

We conducted a comprehensive literature search using PubMed, MEDLINE and Cochrane library from inception to November 2020. All studies comparing the PT weave and STS were included. Methodological quality and assessment of risk of bias were assessed by two independent researchers. Publication bias was assessed using a funnel plot and confirmed by the Begg’s and Egger’s test. The random effects mode was used due to both statistical and clinical heterogeneity among studies.

The initial search resulted in 624 articles; however, after a thorough review, only six studies were selected for inclusion in the meta-analysis and systematic review. We were able to pool findings for maximum load and load to failure. By definition, maximum load is the peak force achieved in tensile testing while load to failure is the first negative inflection of force during the failure test. For maximum load, results showed that there was no evidence that the two tendon repair techniques were significantly different (SMD = –0.84, z = 0.88, p = 0.379, 95% CI = –2.72 – 1.04). However, there was significantly high heterogeneity detected among the included studies (Q=21.10, p = 0.001, I2 = 90.50%, τ2 = 2.47). For load to failure, results indicated that the load to failure was statistically higher in the side-to-side approach (SMD = 1.36, z = 5.26, p = 0.001, 95% CI = 0.85 – 1.86) than the PT approach. It is also notable that a small, non-significant heterogeneity was detected among the included studies (Q=3.66, p = 0.300, I2 = 18.10%, τ2 = 0.05).

STS is stronger than PT weave in terms of load to failure but comparable in terms of maximum load. STS is a possible alternative to PT weave for tendons in need of grafting.

BACKGROUND: The Covid-19 pandemic caused educational institutions to shift from traditional to distance learning. Higher educational institutions offering bachelor’s degrees in Physical Therapy (PT) adapted to the situation by employing various strategies to facilitate learning online. One of the strategies employed is inviting family members as simulated patients in various performance-based assessments (PBA). In the Philippines, the PT department at the University of Santo Tomas made similar changes in the delivery of its courses. Given that family members are one of the primary stakeholders of PT education, it is important to know their experience, insights, and knowledge gained about the profession of PT after playing as a simulated patient (SP) during online performance-based assessments. OBJECTIVES: This study aims to explore how family members describe their experiences playing the role of patients in PT PBAs. METHODS: This study will utilize a phenomenological explorative research design. Family members, including parents, siblings, grandparents, cousins, and household helpers who played the role of a patient in any PT PBAs such as case presentation, case discussion, and practical examination, will be invited to participate. Semi-structured one-on-one interviews will be used for data gathering. Qualitative data from interview transcriptions will be analyzed using thematic analysis using NVivo 12 plus program. EXPECTED RESULTS Family Members will offer experiences in role-playing as patients in PBAs. Main themes and findings will be generated from their sharing that will provide insights regarding the improvement of remote PT PBAs.

Introduction: Prostate cancer is the third most common cancer among Filipino males. Ga-68 PSMA PET-CT and Lu-177 PRLT have been introduced in the Philippines for the diagnostics and therapy of prostate cancer. Objective: The aim of this study is to compare treatment outcomes of standard therapy plus Lu-177 PSMA radioligand therapy and standard therapy alone among patients with prostatic cancer status-post castration using Ga-68 PET-CT as an outcome indicator. Methodology: This is an ambispective cohort study on Ga-68 PSMA PET-CT scans performed between January 1, 2018 and July 31, 2021. Serum PSA data taken within one month of the PET-CT scans were also collected when available. The PET-CT images were reviewed by a radiologist for RECIST response, and by a nuclear medicine physician for PERCIST response . Results: A total of 11 participants were included in the study. Six participants (55.5%) received standard therapy, while five participants (45.5%) received Lu-177 PSMA radioligand therapy plus standard therapy. There was no significant difference in the baseline and follow-up CT as shown by all p values > 0.05. A trend towards higher number of participants with non-complete/non-progressive RECIST response was noted in the control group than the treatment group, as well as higher number of participants with progressive or stable disease using the PERCIST response. Conclusion There were no significant differences noted in the clinical outcomes of participants who received Lu-177 PRLT and those with standard therapy alone. A trend towards decreasing serum PSA, CT and PET measurements were noted among patients given Lu-177 PRLT than those with standard therapy.

INTRODUCTION: Physical therapy students, who train on how to handle patients, also experience burnout due to social, academic, and personal factors. The study aimed to determine the prevalence of burnout among third year physical therapy students of UERM and the factors that contribute to it. METHODS: A descriptive cross-sectional research design was used to determine the prevalence of burnout and its perceived contributing factors. Eligible students answered the Maslach Burnout Inventory General Survey for Students (MBI-GS(S)) and a self-developed questionnaire regarding academic, social, and personal factors of burnout. Microsoft Excel was used to compute the standard (z) values and prevalence rate. RESULTS: None of the 26 respondents fit the criteria to be classified as “burnout”, however 42.3% were “overextended”, 34.6% were “ineffective” and 23.1% were “engaged”. The top factors reported by the participants were too much workload to handle, being left behind academically compared to peers, and pushing oneself too hard for the academic, social, and personal categories, respectively. CONCLUSION None of the limited number of respondents met the criteria for “burnout”. The most perceived academic reason contributing to their burnout is the volume of workload. The feeling of being left behind academically compared to their peers was shown to be the most perceived social factor. The tendency to push themselves too hard to accomplish their task perfectly/completely was seen as the most perceived personal factor in this study.

INTRODUCTION: Since there are limited studies about the return-to-work experiences of Filipino amputees, this study will be able to contribute to studies that delve deeper into the lower extremity amputees’ experiences and put into light the factors that may be present in relation to their return to work. METHODS: This study utilized a qualitative phenomenological design. Participants who were willing to join the study were all gathered for a focus group discussion conducted by a hired interviewer. The researchers adapted Colaizzi’s descriptive phenomenological method for analyzing the data. RESULTS: Factors that allowed amputees to have a successful return to work experience were motivation to continue with life, positive impact of lower extremity prosthesis, and rehabilitation. Factors that hindered the successful return to work of amputees were social barriers, work environment, negative self-image, discrimination from the community, and ft of prosthesis. CONCLUSION Employment was possible after amputation among amputees who were provided with prosthesis at UERMMMCI, since most of the respondents of this study were employed. Positive and negative factors that infuenced their return to work were also identifed. Non-compliance to rehabilitation limited the usage of prosthesis resulting in not being able to return to work.
