Background: The gold standard of treatment for ulnar collateral ligament (UCL) injuries has been reconstruction. Despite early repair studies yielding less than satisfactory results, there has been recent renewed interest in UCL repair due to improved outcomes and new technologies. Data regarding clinical use of these procedures are lacking. The purpose of this study was to define the epidemiological trends of UCL repair and reconstruction surgery from 2010 to 2019, compare demographic characteristics of patients undergoing either procedure, and determine incidence of concomitant procedures in each surgical group as well as comparing respective patient-level charges. Methods: A retrospective database analysis of UCL surgeries was performed through the Texas Healthcare Information Collection database, a comprehensive and publicly available statewide billing dataset. Inclusion criteria were defined using Current Procedural Terminology billing codes for elbow UCL repair and reconstruction between 2010 through 2019, excluding patients who had concomitant elbow fractures or lateral collateral ligament tears indicative of high-energy trauma. Procedural volume changes, patient demographics, and commonly performed concomitant procedures including elbow arthroscopy, ulnar nerve surgery, and platelet-rich plasma injection were compared. Total patient-level charges were compared across groups. Results: A total of 1664 patients were included, consisting of 484 UCL repairs and 1180 reconstructions. Total UCL surgeries increased eleven-fold when corrected for population growth from 2010 (N = 25) to 2019 (N = 315). In 2010, repair constituted 23% of all UCL tear surgeries and increased to 40% by the end of 2019. The annual frequency of UCL repair increased at a 5.4% faster rate than UCL reconstruction from 2010 to 2019 (P

In the new normal, educational institutions find ways for teaching-learning to continue. It is remarkable that distance education has been a great means of continuous learning. In this kind of learning condition, access to quality learning is paramount. The main goal of this research was to determine the effect of the factors of distance education on learning quality during the time of the COVID-19 pandemic. The research design was an exploratory descriptive approach that involved the teachers and students in the Senior High School (SHS) Department of four different campuses. Based on the results, the factors in distance education such as instructional design, support system, and implementation significantly predicted the learning quality of SHS students during the COVID-19 pandemic. When grouped according to campuses, the perceived level of learning quality in distance education noted a significant difference. This may indicate that learning quality can be intensified by the factors in distance education and be carried out on the four campuses. This intensification may be considered in the formulation of the Distance Education Program in the SHS on all campuses of the university.

This study assessed the factors of educational resource management that relate to the quality of work-life among public elementary school teachers. Descriptive-correlational research design was employed to gather data among 534 teaching personnel from 26 public elementary schools in Candelaria District during the academic year 2021-2022. The primary instrument of the study was a researcher-made survey questionnaire distributed using Google forms. The study revealed that physical resources in different schools is managed while time, financial, human, information and communication technology and community resources is well-managed. Moreover, the community and physical/material resources are factors that significantly relate to the respondents’ quality of work-life in terms of job satisfaction, workplace stress, financial reimbursement, working condition, work-life balance, and safety and health based on the regression of variables. However, there is no significant difference in the perceptions of two groups of respondents to educational resource management and level of their quality of work-life. School leaders may prioritize the management of community and physical resources since these are the two factors that can be linked to personnel’s quality of work-life. This is important for all organizational inputs because it leads employee’s satisfaction and influences organizational effectiveness.

This study focused on the preparedness and promotion of technology leadership towards self- efficacy and instructional performance of public elementary school teachers. This utilized 442 public elementary school teachers from Candelaria, Quezon through a descriptive correlational design conducted during academic year 2021- 2022. A researcher- made survey questionnaire was utilized via Google form. The study revealed that self- efficacy was significantly predicted by systematic development when it comes to preparedness of technology leadership while promotion of technology leadership, self- efficacy was significantly predicted by technology infrastructure and support and vision, planning and management. Meanwhile, instructional performance was significantly predicted by systematic development and visionary leadership when it comes to preparedness of technology leadership while promotion of technology leadership, it was significantly predicted by vision, planning and management, technology and infrastructure support, and evaluation and research. This implies that working with peers and doing reflection may also help in enhancing self-evaluation towards teaching performance so teachers can assess points they are good at and they need to develop further.

Abstract Background Direct cannulation of the innominate artery for selective antegrade cerebral perfusion has been shown to be safe in elective proximal aortic reconstructions. We sought to evaluate the safety of this technique in acute aortic dissection. Methods A multi-institutional retrospective review was undertaken of patients who underwent proximal aortic reconstruction for Stanford type A dissection between 2006 and 2016. Those patients who had direct innominate artery cannulation for selective antegrade cerebral perfusion were selected for analysis. Results Seventy-five patients underwent innominate artery cannulation for ACP for Stanford Type A Dissections. Isolated replacement of the ascending aorta was performed in 36 patients (48.0%), concomitant aortic root replacement was required in 35 patients (46.7%), of whom 7 had a valve-sparing aortic root replacement, ascending aorta and arch replacement was required in 4 patients (5%). Other procedures included frozen elephant trunk (n = 11 (14.7%)), coronary artery bypass grafting (n = 20 (26.7%)), and peripheral arterial bypass (n = 4 (5.3%)). Mean hypothermic circulatory arrest time was 19 ± 13 min. Thirty-day mortality was 14.7% (n = 11). Perioperative stroke occurred in 7 patients (9.3%). Conclusions This study is the first comprehensive review of direct innominate artery cannulation through median sternotomy for selective antegrade cerebral perfusion in aortic dissection. Our experience suggests that this strategy is a safe and effective technique compared to other reported methods of cannulation and cerebral protection for delivering selective antegrade cerebral perfusion in these cases.

Transcatheter aortic valve replacement (TAVR) has become a widely adopted treatment modality for severe aortic stenosis. Transfemoral access is the approach of choice; however, approximately 25% of patients undergoing TAVR also have concomitant peripheral arterial disease. The recent advent of intravascular lithotripsy has enabled preservation of transfemoral access in some patients; although, a proportion still require alternative, non-femoral access. Alternative access sites can be broadly categorized into transthoracic and peripheral, facilitated by surgical or percutaneous techniques. In this review, the technical details and clinical outcomes of various TAVR accesses are discussed. Initially, transthoracic approaches were most common, but recently, the trend has been toward alternative peripheral access due to superior outcomes. Although there are no randomized data to support all the alternative access sites, the experiences reported provide available options for a large portion of patients to be candidates for TAVR. The intervention site should be selected by a multidisciplinary heart team based on patient anatomical factors and institutional expertise.

Lagrangian isopycnal diffusivities quantify the along-isopycnal mixing of any tracer with mean gradients along isopycnal surfaces. They are studied in the Southern Ocean of the 1/10° Parallel Ocean Program (POP) model using more than 50 000 float trajectories. Concurrent Eulerian isopycnal diffusivities are estimated directly from the eddy fluxes and mean tracer gradients. Consistency, spatial variation, and relation to mean jets are evaluated. The diffusivities are calculated in bins large enough to reduce contributions from the rotational components that do not lead to net tracer mixing. Because the mean jets are nonzonal and nonparallel, meridional dispersion includes standing eddies and is significantly different from cross-stream dispersion. With the subtraction of the local Eulerianmean, the full Lagrangian diffusivity tensor can be estimated. Along-stream diffusivities are about 6 times larger than cross-stream diffusivities. Along-streamline averages of Eulerian and Lagrangian isopycnal diffusivities are similar in that they are larger north of the Antarctic Circumpolar Current (ACC) and smaller in the ACC in the upper 500 m. Eulerian diffusivities are often twice as large as the Lagrangian diffusivities below 500 m. There is large longitudinal variability in the diffusivities and in their relation to the mean flow. In bins with one prominent jet, diffusivities are reduced at the surface in the jet and increased to the north and south of the jet. There is a local maximum at depths of 500-1000m. In other bins where mean jets merge and diverge because of topography, there is no consistent relation of the diffusivities with the mean flow. Eulerian fluxes are upgradient in about 15% of the bins. © 2014 American Meteorological Society.

This study is focused on the school head's professional identity, emotional intelligence, and perfectionism as three tier factors to advance pedagogical leadership. The study employed the quantitative descriptive methodology, combining descriptive and multiple linear regression analysis. The researchers-made online survey instrument, via a google form. Responses from 132 school heads were analyzed using descriptive statistics such as mean, and standard deviation. Multiple linear regression analysis was employed to determine the significant relationships of the variables. The results reveal that professional identity has a positive relationship with pedagogical leadership. Contradicting result is the emotional intelligence which has a negative relationship with pedagogical leadership. Lastly, perfectionism has a positive relationship with pedagogical leadership. It is concluded that a school head's professional identity, emotional intelligence and perfectionism significantly predict pedagogical leadership. Hence, the department (DepEd) may conduct series of training and workshops for teachers as a capacity building to equip them with knowledge and competencies to handle the numerous challenges in the delivery of quality, relevant, inclusive, and liberating education to the Filipino learners. Further, during Gender and Development programs one activity to consider is the training in emotional development among teachers and school heads. [ABSTRACT FROM AUTHOR]

Dry direct-seeded rice is widely practiced in drought-prone environments in tropical Asia where mechanized options for crop establishment are in great demand. The objective of this study is to identify the suitable design of a hand tractor-mounted multigrain seed drill under biophysical conditions in the Philippines. The prototype was newly designed and tested under field conditions in three provinces in 2015 and 2016. The results suggested that the prototype with tined furrow openers and an inclined circular seed plate in the hopper for seed metering driven by the ground wheel through the combination of chain and sprocket produced rice grain yield similar to the crop established from broadcasting. Field experiments also confirmed that the seed drill has a capacity of over 2 ha day−1 for rice and over 3 ha day−1 for mung bean, and thus, the prototype appears promising for rainfed lowlands in the Philippines.

The drastic development of urban districts around the world has caused changes in the environment, specifically on metropolitan waterways such as the Pasig River in the Philippines. These significant changes resulted in diversity of microorganisms and their mechanisms employed such as antibiotic resistance and their communication system or quorum sensing (QS). In this study, four bacterial isolates from Pasig River, identified as Aeromonas salmonicida, Acinetobacter sp., Morganella morganii, and Citrobacter freundii, were observed to employ short-chain acyl homoserine lactone (AHL) as their signalling molecule based on in vitro assays using the biosensor strain Chromobacterium violaceum CV026. Furthermore, M. morganii isolate was shown to be resistant to chloramphenicol. This poses a significant threat not just to public health but also to the aquatic life present in the river. Thus, green tea (Camellia sinensis) extract was tested for its capability to inhibit in vitro biofilm formation in M. morganii, as well as the short-chain acyl homoserine lactone QS system using C. violaceum ATCC 12472. Results showed that the extract significantly (p < 0.05) inhibited biofilm formation in M. morganii at as low as 62.5 μg/mL (31.55%). Increasing the concentration (500 μg/mL) did not significantly (p > 0.05) enhance the activity (41.21%). Furthermore, the extract also inhibited pigmentation in C. violaceum ATCC 12472, suggesting QS inhibition. This study adds into record the production of short-chain AHLs by Aeromonas salmonicida, Acinetobacter sp., Morganella morganii, and Citrobacter freundii, as well as the potential of green tea extract as inhibitor of biofilm formation in antibiotic-resistant M. morganii possibly through QS inhibition.
