Objective:
There is increased use of 3-dimensional (3D)-printing for manufacturing of interbody cages to create microscale surface features that promote bone formation. Those features may be vulnerable to abrasion and/or delamination during cage impaction. Our objective was to quantify loss of mass and changes in surface topography of 3D-printed titanium interbody cages due to surgical impaction.
Methods:
Eight surfaces of four 3D-printed titanium modular interbody fusion cages were tested. The cages were impacted into the Sawbones model with compression preload of either 200N or 400N using a guided 1-lb (0.45 kg) drop weight. Mass and surface roughness parameters of each endplate were recorded and compared for differences.
Results:
Significant weight loss was observed for the superior endplate group and for both 200N and 400N preloads. For pooled data comparison, significant postimpaction decreases were observed for mean roughness, root-mean-squared roughness, mean roughness depth, and total height of roughness profile. No significant differences were observed for profile skewness and kurtosis. There were significant changes in almost all roughness parameters in the anterior region of the cage postimpaction with significant changes in 2 out of 6 parameters in the middle, posterior, and central regions postimpaction.
Conclusion
Three-dimensional-printed titanium interbody fusion cages underwent loss of mass and alteration in surface topography during benchtop testing replicating physiologic conditions. There was an endplate- and region-specific postimpaction change in roughness parameters. The anterior surface experienced the largest change in surface parameters postimpaction. Our results have implications for future cage design and pre-approval testing of 3D-printed implants.

BACKGROUND AND OBJECTIVE
Filipino farmers face unique occupational challenges that increase the risk of mental health issues, particularly anxiety. This study aims to determine the different personal, environmental, socioeconomic, occupational, and psychosocial factors associated with anxiety symptoms among Filipino farmers in Central Luzon.
METHODSChain referral sampling method was used to recruit participants for the study, who underwent screening based on the eligibility criteria. Eligible participants were then asked about anxiety symptoms using the Generalized Anxiety Disorder-7 (GAD-7), while the validated, researcher-constructed Data Collection Tool for Factors Associated with Anxiety Symptoms (DCFAAS) was used to determine the farmers’ exposure to a variety of factors. Microsoft Excel was utilized in computing for frequency and percent distribution of participants, in each factor. Binary logistic regression was used to compute crude and adjusted odds ratio of each factor thru IBM SPSS Statistics®.
RESULTSAmong the 113 eligible farmers enrolled in the study, only 19 (16.8%) experienced anxiety symptoms, with excessive worrying, which was seen among 45 participants (39.8%). The mental health of Filipino farmers was significantly affected by the presence of physical illness (OR = 10.70 [95% CI 1.367, 83.773]) and having relatives affecting work completion (OR = 6.45 [95% CI 1.346, 30.896]).
CONCLUSIONDespite the low prevalence of anxiety symptoms in this study, the findings suggest government policies to improve mental health service access to farmers, to integrate psychosocial support into agricultural programs, and to address family-related work pressures. By addressing these factors, it can improve farmer productivity and promote overall well-being, putting emphasis on the mental health of the Filipino farmers.

BACKGROUND
Medication compliance contributes to preventing significant morbidities, such as stroke, among hypertensive patients.
OBJECTIVEThis study aimed to examine the factors affecting hypertensive patients' medication compliance in Sambag II, Cebu City.
METHODSThis study is an observational cross-sectional study. The study was conducted in Barangay Sambag II of Cebu City and involved 170 random, voluntary, self-reporting hypertensive patients. The Tao Yamane formula was used to determine the sample size. An interviewer-guided survey questionnaire was utilized to collect the data for the pilot study. The data were analyzed using Cronbach’s Alpha Test for internal consistency and reliability.
RESULTSThree factors were shown to influence compliance with antihypertensive medications. These are the source of medication, access to medication, and symptoms experienced before intake of anti-hypertensive medications. A factor that significantly affects compliance is the source of medication, wherein hypertensive patients prefer medications from retail pharmacies compared to the free medications supplied by the local health center.
CONCLUSIONResidents of Sambag II, Cebu City preferred medications from retail pharmacies over the free medications provided by the local health center. Local health units may use this information to implement information drugs regarding the efficacy of medications provided by government agencies. Further studies are recommended to use subgroup analysis on factors influencing compliance and non-compliance to anti-hypertensive medicines.

OBJECTIVE
Preterm birth is a major cause of complications leading to death of children under 5 years old. Infections are important to be identified because antimicrobial treatment may prevent or delay progression to preterm delivery. This study determined if routine screening tests of infections are useful in the clinical management of preterm labor.
METHODSA cross-sectional (descriptive) study was done involving 417 pregnant patients who had preterm labor and was subsequently admitted from 2015 to 2019 at a tertiary hospital in the Philippines, using review of past medical records, inpatient charts, and admission charts.
RESULTSMajority of the patients delivered at less than 34 weeks, most of the culture results turned out negative, and urine tests were more commonly employed as screening tests for preterm labor. The endocervical and rectovaginal swab studies had no significant growths. Asymptomatic bacteriuria was diagnosed in 1 out of 10 patients and they were subsequently started on antibiotic treatment. Majority of the patients who were given antibiotics delivered within 48 hours from admission.
CONCLUSIONThe routine use of cultures in the assessment of preterm labor is costly and is unlikely to be helpful in the clinical management of patients in preterm labor.

BACKGROUND AND OBJECTIVES
Many patients have received acupuncture treatment to address various health problems and it has been presented in several studies to be effective. However, stories of patients on the use of acupuncture may present some additional information including contextual factors about acupuncture treatment. This study was conducted to explore experiences of patients in a community-based acupuncture clinic on the impact of acupuncture as a treatment modality. In particular, this study aimed to understand how acupuncture has changed patients’ lives through a life stories approach, describe how the treatment affected their perceptions about their well-being, and to elicit their views of the acupuncture as an alternative or complementary treatment.
METHODSA narrative inquiry was done using in-depth interviews individually conducted among eight participants, who were selected purposively based on having had at least 12 consecutive acupuncture sessions at a communitybased acupuncture clinic. All the interviews were audio-recorded and later transcribed by a professional external interviewer following written informed consent from all the participants. The research protocol was submitted and approved by the Ethics Review Committee of the University Research Institute for Health Sciences. The researchers analyzed the interview transcripts using Murray’s narrative analysis approach.
RESULTSParticipants’ stories highlighted their personal experiences of how they had come to know about acupuncture, how their experiences have changed their perceptions of the treatment, and how the outcomes of acupuncture treatment have affected their lives. The findings emphasize four narratives: pain relief, acupuncture being complementary to Western medicine, social support, and advocacy.
CONCLUSIONThis study emphasizes qualitative findings that are essential to be considered in the implementation of community-based acupuncture clinics that may help make acupuncture care accessible to community residents as well as maximize the potential of this treatment modality.

BACKGROUND AND OBJECTIVES
The global pandemic caused by Coronavirus Disease 2019 (COVID-19) has affected millions, with growing evidence of the potential role of ocular tissues in viral transmission. At the time of writing, local data regarding the phenomenon was limited. This study investigated external ocular manifestations in patients with COVID-19 at a referral center in the Philippines, examined correlations between demographics, systemic manifestations, and laboratory results with ocular manifestations, and determined their timing relative to systemic symptoms.
METHODSThis single-center, descriptive cross-sectional study was carried out from December 8 to 18, 2020 at the adult COVID-19 wards of the Philippine General Hospital involving 72 participants. Data collection involved relevant clinical history taking and performing gross eye examination. The prevalence of ocular manifestations was described with 95% confidence intervals. Correlations between ocular manifestations and quantitative variables were analyzed with point-biserial correlation, and associations with qualitative variables were tested using chi-square or Fisher’s exact tests.
RESULTSAmong participants, 31.9% presented with ocular manifestations with foreign body sensation as the most prevalent ocular symptom (11.1%) and conjunctival hyperemia as the most prevalent ocular finding (19.4%). The median age of patients with ocular manifestations was 41 years old with a higher prevalence in the male population (73.9%, CI=95%, p=0.001). No significant correlation was observed between presence of external ocular manifestations and the different systemic and ocular co-morbidities as well as with COVID-19 clinical classification. Among those who experienced symptoms, majority (29.2%) of the patients experienced systemic symptoms prior to the onset of ocular symptoms. Ocular complaints may present as the sole manifestation (13.9%). Several laboratory parameters were measured and only temperature and AST levels showed a low positive correlation with the presence of ocular manifestations.
CONCLUSIONOcular manifestations occur in roughly one third of patients with COVID-19 based on this study population. With some individuals presenting with ocular signs or symptoms as the initial and sole manifestation, healthcare practitioners must exercise caution and remain vigilant in managing patients who present as such. At the time of writing, this is the first local study investigating the different external ocular manifestations in patients with COVID-19. There is a need to pursue more robust studies and conduct more local investigations which will guide both ophthalmologists and other practitioners in strengthening existing guidelines regarding precautionary practices, clinical diagnosis, and management of COVID-19 patients.
