BACKGROUND AND OBJECTIVE

Public health nurses (PHNs) are vital in the local implementation of the provisions of the Universal Healthcare (UHC) Act of 2019. However, they need adequate competencies in health systems approach to successfully implement the provisions of the law. In response to this, a leadership development course for public health nurses (LDC-PHN), anchored on the building blocks of health systems, was developed and implemented. This paper aims to describe the extent to which training participants have applied the competencies acquired from the LDC-PHN as manifested by the workplace application of their capstone projects.

Following Kirkpatrick’s Model of Evaluation, we used a multi-method study design to evaluate the extent of the participants’ workplace application of acquired competencies. Sources of data included the Workplace Application Plan (WAP) accomplished by each participant, a questionnaire to determine the perceived implementation status of the participants’ capstone project, interviews, and focus group discussions (FGDs) conducted with selected participants and their supervisors, and observation visits. Data were collected from May to December 2022. Data from the semi- structured interviews and FGDs were analyzed through content analysis, while the participants’ perceived status of their capstone project implementation was summarized as frequencies.

Majority of the participants (61.9%) reported partial implementation of their capstone project while 16.77% reported full implementation. Capstone project implementation was facilitated by the support received from their supervisors and local chief executives. Barriers identified included the demands of the COVID-19 pandemic and the challenges imposed by the events before and after the 2022 Philippine National elections. Major themes emerged from the interviews conducted among participants and their supervisors. The workplace application of the training program outcomes, based on participants’ perspectives, yielded increased capacity to lead and innovate, improved ability to advocate for capstone project implementation, transferability of acquired skill sets, and improved population outcomes. From supervisors’ perspectives, workplace application of training program outcomes include increased ability of PHNs to deliver health services, and visible enhancement of leadership and supervision skills among PHNs.

Given ample support and opportunities, and despite the barriers and challenges they faced, LDC-PHN participants, in general, utilized and applied the competencies they gained from the course in their actual work setting. Course graduates participated in health systems strengthening at various capacities by acting upon their capstone projects that addressed UHC challenges within their particular work settings.

Objective: To describe the trend and landscape of Coronavirus Disease (COVID-19)-related publications in nursing authored by at least one Philippine-based author. Methods: This study is a bibliometric analysis of documents retrieved from Scopus using the search terms “COVID-19” and “nurs*” in the article title, abstract, and keywords. The documents were limited to those published in English, affiliated with Philippine-based authors, and those published from 2020 to 2023. We used the ‘analyze report’ function in Scopus to analyze the data including the number of publications, types, sources, authors, and affiliations. We used VOSViewer for the co-authorship analysis of countries and co-occurrence analysis of author keywords. Results: A total of 136 documents were found. Majority of these documents were classified as original articles (83%). There was a rapid increase in COVID-19 publications in nursing authored by at least one Philippine-based researcher published from 2020 to 2021 and plateaued from 2022-2023. Co-authorship analysis showed that Philippine-based authors have written documents with authors from 111 countries most notably from Saudi Arabia, the United States, Indonesia, and Australia. Most documents were published in the Belitung Nursing Journal. Authors from the University of Santo Tomas had the most publications. The most cited articles focused on psychosocial impacts, resilience, workplace stress, and online education. Author keywords commonly used in the documents were COVID-19, nursing, and nursing students, covering topics such as pandemic impacts, workplace impacts, nurse well-being, psychosocial impacts, and nursing education. Keywords have evolved through the pandemic period with a recent focus on stress and professional values. Conclusion Philippine-based authors actively contributed in understanding the impact of COVID-19 on nurses and nursing education. Their scientific productivity was driven partly by their collaboration with foreign-based researchers. To sustain this trend in productivity and collaboration, policies, programs, and strategies are needed to promote, support, and foster research collaboration among local and international nursing researchers and institutions.

Extracellular vesicles (EVs) function as potent mediators of intercellular communication for many in vivo processes, contributing to both health and disease related conditions. Given their biological origins and diverse functionality from correspondingly unique “cargo” compositions, both endogenous and modified EVs are garnering attention as promising therapeutic modalities and vehicles for targeted therapeutic delivery applications. Their diversity in composition, however, has revealed a significant need for more comprehensive analytical-based characterization methods, and manufacturing processes that are consistent and scalable. In this review, we explore the dynamic landscape of EV research and development efforts, ranging from novel isolation approaches, to their analytical assessment through novel characterization techniques, and to their production by industrial-scale manufacturing process considerations. Expanding the horizon of these topics to EVs for in-human applications, we underscore the need for stringent development and adherence to Good Manufacturing Practice (GMP) guidelines. Wherein, the intricate interplay of raw materials, production in bioreactors, and isolation practices, along with analytical assessments compliant with the Minimal Information for Studies of Extracellular Vesicles (MISEV) guidelines, in conjunction with reference standard materials, collectively pave the way for standardized and consistent GMP production processes.

Methods: A prospective randomized study of 76 patients who underwent lumbar and thoracolumbar surgeries was conducted by randomly allocating patients into three anesthetic groups: GA alone, GA with spinal anesthesia (SA), and GA with erector spinae plane block (ESPB) by the allocation concealment method to avoid selection bias. The working conditions were assessed by the same operating surgeon who was blinded by the type of anesthesia to eliminate the assessment bias. Muscle relaxation and surgical field were compared among the three groups along with other hemodynamic parameters to identify any significant differences. Results: Significantly better muscle relaxation, surgeon satisfaction, postoperative analgesia, and blood pressure (BP) were observed in the GA+RA when compared to GA alone (p <0.01), whereas no difference was observed between the GA+SA and GA+ESPB groups (p >0.05). Complications were only observed in the GA+SA group (19%). Conclusions The study results suggest that the addition of RA to GA may provide better working conditions and surgeon’s satisfaction by improving relaxation of the erector spinae in addition to decreasing the BP and postoperative pain in contrast to the use of GA alone. The combined GA and ESPB techniques may be a viable anesthetic alternative to provide better working conditions for surgeons.

Methods: Patients >18 years old who underwent primary one- or two-level TLIFs at our institution were identified and propensitymatched in a 3:1 fashion (unilateral:bilateral). Patient demographics, surgical characteristics, and radiographic outcomes, including vertebral endplate obliquity, segmental lordosis, subsidence, and fusion status, were compared between groups. Results: Of the 184 patients included, 46 received bilateral cages. Bilateral cage placement was associated with greater subsidence (1.06±1.25 mm vs. 0.59±1.16 mm, p=0.028) and enhanced restoration of segmental lordosis (5.74°±14.1° vs. −1.57°±10.9°, p=0.002) at the 1-year postoperative point, while unilateral cage placement was associated with an increased correction of endplate obliquity (−2.02°±4.42° vs. 0.24°±2.81°, p<0.001). Bilateral cage placement was significantly associated with radiographic fusion on bivariate analysis (89.1% vs. 70.3%, p=0.018) and significantly predicted radiographic fusion on multivariable regression analysis (estimate, 1.35; odds ratio, 3.87; 95% confidence interval, 1.51–12.05; p=0.010). Conclusions Bilateral interbody cage placement in TLIF procedures was associated with restoration of lumbar lordosis and increased fusion rates. However, endplate obliquity correction was significantly greater for patients who received a unilateral cage.

Methods: All patients aged >18 years who underwent primary one- to four-level ACDF at a single institution were retrospectively identified. Propensity matching was performed to compare patients’ PEEK or titanium alloy cages with structural allograft. Multivariate logistic regression analysis was performed to measure the effect of interbody spacer composition on the likelihood of pseudarthrosis development. Results: Of the 502 patients who received structural allograft and had 1-year postoperative dynamic radiographs, 96 patients were propensity matched to 32 patients who received a PEEK cage, and 162 patients were propensity matched to 54 patients who received a titanium alloy cage. Multivariate logistic regression analysis identified that PEEK cage implants (odds ratio [OR], 3.34; p =0.007) predicted pseudarthrosis development compared with structural allograft implantation. Titanium alloy cage (OR, 1.64; p =0.156) implantation was not predictive of pseudarthrosis. One-year postoperative PROMs were not significantly different between patients who received PEEK or titanium alloy cages and those who received structural allograft (all p >0.05). Conclusions Compared with structural allograft, receiving a PEEK cage increased the risk of pseudarthrosis development following ACDF, whereas receiving a titanium alloy cage had no significant effect on pseudarthrosis development. One-year postoperative patient-reported outcomes were similar between patients who received structural allograft, PEEK, and titanium alloy interbody spacers.

Emerging therapies based on localized delivery of siRNA to lungs have opened up exciting possibilities for treatment of different lung diseases. Localized delivery of siRNA to lungs has shown to result in severalfold higher lung accumulation than systemic route, while minimizing non-specific distribution in other organs. However, to date, only 2 clinical trials have explored localized delivery of siRNA for pulmonary diseases. Here we systematically reviewed recent advances in the field of pulmonary delivery of siRNA using non-viral approaches. We firstly introduce the routes of local administration and analyze the anatomical and physiological barriers towards effective local delivery of siRNA in lungs. We then discuss current progress in pulmonary delivery of siRNA for respiratory tract infections, chronic obstructive pulmonary diseases, acute lung injury, and lung cancer, list outstanding questions, and highlight directions for future research. We expect this review to provide a comprehensive understanding of current advances in pulmonary delivery of siRNA.

Background: and Purpose High-grade carotid artery stenosis may alter hemodynamics in the ipsilateral hemisphere, but consequences of this effect are poorly understood. Cortical thinning is associated with cognitive impairment in dementia, head trauma, demyelination, and stroke. We hypothesized that hemodynamic impairment, as represented by a relative time-to-peak (TTP) delay on MRI in the hemisphere ipsilateral to the stenosis, would be associated with relative cortical thinning in that hemisphere. Methods: We used baseline MRI data from the NINDS-funded Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis–Hemodynamics (CREST-H) study. Dynamic contrast susceptibility MR perfusion-weighted images were post-processed with quantitative perfusion maps using deconvolution of tissue and arterial signals. The protocol derived a hemispheric TTP delay, calculated by subtraction of voxel values in the hemisphere ipsilateral minus those contralateral to the stenosis. Results: Among 110 consecutive patients enrolled in CREST-H to date, 45 (41%) had TTP delay of at least 0.5 seconds and 9 (8.3%) subjects had TTP delay of at least 2.0 seconds, the maximum delay measured. For every 0.25-second increase in TTP delay above 0.5 seconds, there was a 0.006-mm (6 micron) increase in cortical thickness asymmetry. Across the range of hemodynamic impairment, TTP delay independently predicted relative cortical thinning on the side of stenosis, adjusting for age, sex, hypertension, hemisphere, smoking history, low-density lipoprotein cholesterol, and preexisting infarction (P=0.032). Conclusions Our findings suggest that hemodynamic impairment from high-grade asymptomatic carotid stenosis may structurally alter the cortex supplied by the stenotic carotid artery.

Achievement of Universal Health Care (UHC) in the Philippines requires capable health workers who can navigate changes and lead in the local implementation of health system reforms. Public health nurses are in a strategic position to lead in UHC implementation as they constitute the largest cadre of health workers in the public health setting, and core concepts of UHC intersect with principles of public health nursing practice. This paper aims to describe the development and implementation of a leadership training program for public health nurses in the Philippines, in response to UHC. Document reviews of training reports and evaluations, including course site data analytics, and evaluation of the training program were done for the four cohorts of the course. The University of the Philippines Manila College of Nursing, with support from the Department of Health, responded to the increased demand of the Philippine health system for public health nurses with strong foundations and advanced skills by designing and offering a leadership development course specific to PHNs. From November 2019 to March 2022, a total of 183 participants from 17 regions completed the training. With the COVID-19 pandemic and dynamic changes in governance, the experiences of the project highlighted the need for flexibility in delivering the training program, updating module contents according to the latest developments, and improving course duration and evaluation. Barriers to course engagement and completion must be addressed for PHNs, their workplaces, clients, and the health system to benefit the most from the training.

Background: While online orthopedic resources are becoming an increasingly popular avenue for patient education, videos on YouTube are not subject to peer review. The purpose of this cross-sectional study was to evaluate the quality of YouTube videos for patient education in ulnar collateral ligament (UCL) injuries of the elbow. Methods: A search of keywords for UCL injury was conducted through the YouTube search engine. Each video was categorized by source and content. Video quality, reliability, and accuracy were assessed by two independent raters using five metrics: (1) Journal of American Medical Association (JAMA) benchmark criteria (range 0–4) for video reliability; (2) modified DISCERN score (range 1–5) for video reliability; (3) Global Quality Score (GQS; range 1–5) for video quality; (4) ulnar collateral ligament-specific score (UCL-SS; range 0–16), a novel score for comprehensiveness of health information presented; and (5) accuracy score (AS; range 1–3) for accuracy. Results: Video content was comprised predominantly of disease-specific information (52%) and surgical technique (33%). The most common video sources were physician (42%) and commercial (23%). The mean JAMA score, modified DISCERN score, GQS, UCL-SS, and AS were 1.8, 2.4, 1.9, 5.3, and 2.7 respectively. Conclusions Overall, YouTube is not a reliable or high-quality source for patients seeking information regarding UCL injuries, especially with videos uploaded by non-physician sources. The multiplicity of low quality, low reliability, and irrelevant videos can create a cumbersome and even inaccurate learning experience for patients.
