INTRODUCTION
Hypertension is a serious public health issue that puts individuals at risk for various morbidity and mortality indicators. One of the most crucial factors in managing blood pressure and preventing complications is medication adherence which is linked to several determinants. This study explored the correlation between medication adherence among middle-aged hypertensive adults and the different domains of quality of life (QOL), which includes physical, psychological, social relationship and environment.
METHODSThis cross-sectional study involved 96 Filipino residents of Brgy. San Jose, Navotas City aged 35 to 65 years old diagnosed with hypertension and prescribed anti-hypertensive medications. Pearson’s correlation coefficient was used to calculate the correlation between different domains of QOL as well as the overall QOL score.
RESULTSResults revealed a statistically significant but weak positive correlation between overall QOL and medication adherence (r = 0.336, p<0.001). Among the QOL domains, environmental domain had the strongest correlation with adherence (r = 0.446, p = 0.00), followed by physical health (r = 0.443, p = 0.01) and psychological well-being (r = 0.382, p = 0.01). The social relationship domain showed negligible correlation (r = 0.163, p = 0.4).
CONCLUSIONThe study demonstrates that while medication adherence is modestly associated with better perceived QOL, especially in physical, psychological and environmental aspects, other factors likely influence both outcomes. These findings highlight the need for holistic, community-based interventions that address not only medication adherence but also environmental and psychosocial barriers to care in managing hypertension.

WAGR syndrome is a rare congenital disorder, occurring in approximately 1 in 500,000 to 1,000,000 individuals, often presenting with ocular malformations such as aniridia. Glaucoma frequently develops when the iris and angle structures are affected, posing a significant risk of vision loss. We report a one-year and seven-month-old patient who presented with corneal opacity of the left eye. Examination revealed corneal opacity, aniridia, and markedly elevated intraocular pressure of 65 mmHg, while the fellow eye, also with aniridia, was normotensive. The patient underwent immediate combined trabeculectomy-trabeculotomy. Postoperative follow-up and timely management of complications allowed acceptable pressure control over one year, though visual prognosis remained guarded. This case highlights the challenges of managing glaucoma in WAGR syndrome, particularly in resource-limited settings. Medical therapy alone is often insufficient, making surgical intervention essential. Combined trabeculectomytrabeculotomy proved effective in maintaining pressure control when glaucoma drainage devices were not feasible. Multiple interventions and close monitoring are frequently required due to the risk of scarring and postoperative complications. Our experience emphasizes the need for a multidisciplinary ophthalmology approach to optimize outcomes. Despite pressure control, visual outcomes often remain poor due to structural anomalies and the challenges inherent to pediatric patients with this rare syndrome.

BACKGROUND
Corticosteroids have been used in ophthalmology for its potent anti-inflammatory and immunosuppressive actions. Although the role of corticosteroid treatment is pivotal in the treatment of numerous inflammatory diseases and as postoperative management of patients who undergo ocular surgeries, intraocular pressure (IOP) elevation has been a significant ocular side effect that could result after steroid use. Evaluating the changes in IOP in pediatric eyes will provide early detection and timely intervention to prevent glaucomatous optic neuropathy.
OBJECTIVEThis study aimed to determine the incidence of IOP elevation among pediatric patients given corticosteroids after strabismus surgery in a tertiary hospital in Manila, Philippines.
METHODSThis is a single-center, retrospective, observational study that employs review of the clinical records of pediatric patients who underwent strabismus surgery between January 2015 and December 2022. This study was conducted last February to November 2023. Data were gathered and descriptively summarized regarding patient demographics, ophthalmologic diagnosis, type of strabismus surgery performed, preoperative and postoperative IOP readings, frequency and duration of postoperative topical steroid use, and treatment received and response to elevated IOP.
RESULTSForty-five (28.48%) out of the 158 pediatric patients who had strabismus surgery during the study period met the inclusion criteria for the study. The mean age of pediatric patients was 11.38 ± 5.28 years (range 2-18 years old). There were more males (55.6%) than females. All patients were administered Tobramycin + Dexamethasone eyedrops, ointment or both. The baseline, peak, and net change in IOP were 13.5 ± 2.7 mmHg, 23.1 ± 8.8 mmHg and 10 ± 8.4 mmHg respectively. IOP increased in thirty-seven (82.2%) of the patients from baseline, and 21 (56.7%) of them had a considerable rise. For most patients with considerable rise of IOP, topical steroid medication was either stopped or immediately tapered off. Nine patients received topical IOP-lowering medicine, and most of them returned to normal IOP levels two months following surgery. After then, topical IOP-lowering drugs were stopped.
CONCLUSIONIOP elevation following strabismus surgery was frequently associated with topical steroid usage, and most patients experienced considerable IOP elevation. It is highly advised to closely monitor IOP following strabismus surgery, particularly in children receiving topical steroid treatment.

RATIONALE/OBJECTIVE
Hemifacial spasm (HFS) is painless, paroxysmal, repetitive twitching of the unilateral facial muscle initially starting with the orbicularis oculi progressing to mid and lower facial muscles. This condition can be disabling and affect quality of life. Microvascular decompression (MVD) offers t he m ost permanent treatment and outcomes are measured through cessation of spasm. There are currently no Filipino-translated questionnaires to measure the quality of life (QOL) of patients with HFS. This study translated and validated the HFS-7 questionnaire and used it to assess and compare the preoperative and postoperative QOL of patients with HFS following MVD.
METHODSThe HFS-7 questionnaire was translated to Tagalog using a “forward–backward” translation method by 2 independent linguists. The translated questionnaire was validated by 4 expert neurosurgeons and were sent to 27 HFS patients to retrospectively assess pre-op and post-op QOL.
RESULTSTwenty out of 27 HFS patients answered the survey. Majority of HFS patients were middle-aged females. The Criterion Validity Index (CVI) showed a result of 1 which indicates good validity of the translated HFS-7. It has good reliability with Cronbach alpha score of 0.97. T-test comparing the pre-op and post op scores showed that there is a significant improvement in QOL of HFS patients after MVD.
CONCLUSIONIn patients with HFS, MVD offers an improvement of postoperative versus preoperative quality of life measurements. The Tagalog-translated HFS-7 questionnaire is a valid and reliable objective tool in measuring this treatment outcome.

Introduction:
Hypertension is common in obesity and increases
cardiovascular risk. Bariatric surgery improves metabolic
health, but subgroup differences in blood pressure response
remain unclear. This study examined 1-year changes in
systolic blood pressure (SBP) and diastolic blood pressure
(DBP) after bariatric surgery across sex, age group, and
diabetes status.
Methodology:
This study included 32 obese adults undergoing bariatric
surgery, with blood pressure measured at baseline, 6
and 12 months. Generalized estimating equation models
were used to evaluate changes in SBP and DBP over time,
adjusting for age, sex, surgery type, diabetes category,
baseline body mass index, antihypertensive medication
use, and baseline blood pressure. Interaction terms were
tested to assess differences in blood pressure trajectories
across subgroups.
Results:
Participants were predominantly female (67.4%), with a
mean age of 36.9 ± 6.2 years and a mean body mass index
of 40.7 ± 8.8 kg/m². Hypertension and diabetes were present
in 40.6 and 31.3% of participants, respectively. There was a
significant time effect for both SBP (p <0.001) and DBP (p
= 0.004). At 12 months post-surgery, mean SBP decreased
by 15 mmHg and DBP by 7.9 mmHg compared with
baseline (both p <0.001). No significant interactions were
observed between time and sex, diabetes category, or age
category, indicating that blood pressure improvements
were comparable across subgroups.
Conclusion
Bariatric surgery was associated with clinically meaningful
reductions in both SBP and DBP, with similar improvement
patterns observed across demographic and metabolic subgroups. These findings support the effectiveness of bariatric
surgery as a strategy for blood pressure reduction and
cardiovascular risk management in patients with obesity.

OBJECTIVE:
To establish a three-dimensional finite element model of a digital wire loop space maintainer for the mandible and primary tooth loss, in order to investigate the stress, deformation, and shear force experienced by patients with the loss of the second primary molar when wearing the wire loop space maintainer.
METHODS:
Cone beam computed tomography (CBCT) scans were performed on the patients to create a digital model of the mandible with the absence of the second primary molar using Mimics 21.0 software. A digital model integrating the crown's retention and the wire loop structure of the full crown and ring wire loop space maintainer was constructed using pediatric space maintainer design software, utilizing three different materials: cobalt-chromium alloy, polyether ether ketone (PEEK), and titanium alloy. In ANSYS Work Beach 2023 R2 software, vertical loads of 70 N, tilted 45° along the long axis of the tooth loads of 70 N, and a 10 N load on the surface of the wire loop were applied to the occlusal surfaces of models 46 and 84, simulating centric and lateral occlusions during chewing with the wire loop space maintainer in place. The stress states of the wire loop space maintainer and supporting teeth were analyzed.
RESULTS:
Under various loading conditions, the maximum principal stress of the ring wire loop space maintainer was significantly lower than that of the full crown. Stress contour maps indicated that the peak of the maximum principal stress occurred at the junction of the wire loop and crown structure, indicating that this area was more susceptible to fracture. The ring wire loop space maintainer made from PEEK material exhibited the lowest maximum shear stress on the internal organizational surfaces, with equivalent stresses of 23.18 MPa and 36.35 MPa for models 46 and 84, respectively. Stress contour maps demonstrated that the maximum stress on tooth 46 was located at its mesial, while the maximum stress on tooth 84 was situated near the root area on its distal, in contact with the wire loop space maintainer.
CONCLUSION
In cases of second primary molar loss, wearing the digital ring wire loop space maintainer can effectively distribute stress, and the ring wire loop space maintainer made from PEEK material reduces the stress experienced by supporting teeth to some extent, demonstrating its superiority in clinical application.

The gradient coils of MRI equipment can induce vibrations in implantable medical devices, causing periodic vibrations of implantable medical devices with respect to the surrounding tissue. This not only results in instrument failure but also causes discomfort to the patient. Therefore, studying the vibration characteristics of implantable devices under different scanning sequences and the orientation of the device relative to the magnetic field is crucial for comprehending vibration performance. This study observed the vibration spectra of a full cranial bone-implanted neurostimulator by using laser vibrometry under typical rapid imaging sequences and explored the impact of different magnetic field orientations on vibration. The results demonstrated that the rapid echo sequences induced diverse and rich vibration components, whereas the planar echo sequences caused relatively simple vibrations. Additionally, the strongest vibrations normally occurred in the maximum conductive surface parallel to the phase-coded direction. It revealed the factors influencing the vibrations of skull fixation active implantable devices and provided guidance for enhancing device safety and protecting patient well-being during MR examinations.

8.Finite Element Simulation Analysis of a Nickel-Titanium Alloy Patent Foramen Ovale Occluder.
Chinese Journal of Medical Instrumentation 2025;49(2):119-124
In this paper, a preliminary stress/strain analysis of the design structure of a nickel-titanium alloy patent foramen ovale occluder is conducted with the finite element simulation analysis method. In the analysis, solid structure modeling is carried out on three different specifications of domestic patent foramen ovale occluders. Referring to the test method of fatigue performance in inspection standard YY/T 1553-2017, an initial installation deformation is applied to the model, and then the fatigue displacement of 2 mm is applied to the sample to make the model fatigue deformation. The fatigue safety factors of each type of occluder are obtained by strain simulation analysis. The results indicate that the minimum fatigue safety factors of the three specifications of domestic patent foramen ovale occluders are 2.09, 2.35 and 2.06 respectively, which all meet the design of fatigue safety factor greater than 1. Among them, 1818 and 3030 specifications of patent foramen ovale occluders have close values in minimum fatigue safety factors, and both are lower than that of 1825 model. Therefore, it is recommended to carry out physical fatigue tests on both 1818 and 3030 specifications to further verify the fatigue performance of the products.

This study investigated a novel coronary knobby scoring balloon through finite element analysis (FEA) and in vitro anti-slippage testing, evaluating its dilation process under various vascular conditions and comparing it with other balloons. The FEA results indicated that in the cases of healthy artery and diseased artery with different stenosis rates, the stress on the vessels caused by the knobby scoring balloon was significantly smaller than that of the scoring balloon, and was close to that of the plain balloon. In vitro anti-slippage testing showed that the slippage distance of a plain balloon was 0.11±0.06 mm, and there was no slippage for knobby scoring balloon under nominal pressure. Knobby scoring balloon can effectively expand calcified lesion while providing anti-slippage function, and has a lower risk of vascular injury.

Chinese Journal of Medical Instrumentation 2025;49(3):330-335
OBJECTIVE:
The study investigates the performance parameters of a nebulizer for pressurized intraperitoneal aerosol chemotherapy (PIPAC).
METHODS:
Laser diffraction spectroscopy was used to measure the median droplet diameter ( D 50) and spray angle during the steady-state aerosol phase.
RESULTS:
The minimum droplet diameter of aerosol was achieved when using a nozzle of 0.2 mm diameter and 0.07 mm thickness. The nebulizer could not produce steady-state aerosol when the liquid flow rate was less than or equal to 0.3 mL/s. When the liquid flow rate was greater than or equal to 0.5 mL/s, as the working pressure increased, the median particle size gradually decreased and the spray angle gradually increased. When the pressure is greater than or equal to 200 psi(1 psi=6 894.76 Pa), as the liquid flow rate increased, the spray angle gradually increased. At a flow rate of 0.7 mL/s and working pressure of 300 psi, the median droplet diameter of aerosol D 50 was 16 μm with a spray angle up to 89.2°.
CONCLUSION
As a novel intraperitoneal drug delivery technology, PIPAC requires further research focusing on reducing droplet size, expanding drug distribution, improving tissue permeability, and increasing drug concentration.
