OBJECTIVE
To compare the refractive absolute error when axial length (AL), anterior chamber depth (ACD) and keratometry (K) are sourced from different measuring devices (IOL Master vs a combination of automated keratometer and A-scan) and inputted into the Barrett Universal II or SRK/T formula.
METHODSThis was a retrospective study. Medical charts of eyes that underwent uncomplicated phacoemulsification with in-the-bag implantation of Envista or multifocal FineVision IOL were reviewed. The results of manifest refraction at 1 month after surgery were collected. The predicted refraction corresponding to the IOL power implanted was collected from 4 IOL sheets: using the SRK/T with AL, ACD, and K from IOL Master (Group A); SRK/T formula with AL and ACD from A-scan and K from the automated keratometer (Group B); Barrett formula with AL, ACD and K from IOL Master (Group C); and Barrett formula using with AL, ACD from A-scan and K from automated keratometer. For each group, the absolute error, prediction error, and variances of prediction error were computed.
RESULTSA total of 132 eyes were included in the study: 56 in the monofocal group and 76 in the multifocal group. The means of manifest refraction spherical equivalent (MRSE) were 0.06 ± 0.38 D and –0.08 ± 0.31 D in the monofocal and multifocal groups, respectively. When AL and K were obtained from various sources and entered into the Barrett formula, the mean absolute error difference in both the monofocal (p = 0.70) and multifocal (p = 0.10) groups did not reach statistical significance. If the SRK/T formula was used, similar outcomes were observed (monofocal p = 0.97; multifocal p = 0.37). When compared to A-scan groups, the prediction error variances are significantly smaller in the groups that used the IOL Master as their data source. Among the four groups, the Barrett group using IOL Master as the data source showed the lowest overall variation of prediction error (monofocal F = 0.04; multifocal F = 0.03).
CONCLUSIONThough the refractive outcomes may not be statistically different, using the IOL Master as the source of AL and K makes the refractive outcomes more consistent and predictable. Combining the AL and K from the IOL Master with the Barrett Universal II formula further increases the predictability of refractive outcomes.

Introduction:
In 2021, the International Diabetes Federation, reported 536 million people with diabetes, mainly from countries with lower income.
Methods:
A cross-sectional descriptive study was employed using the Finnish Diabetes Risk Score (FINDRISC), a validated questionnaire which determines the risk of developing diabetes. The questionnaire was conducted online to be accomplished by students enrolled in universities located in Quezon City.
Results:
Among the 178 college students in Quezon City, with average age of 20 years old, 28.1% are
at risk of developing T2DM. The factors contributing to the risk were: (1) Lack of physical activity of at
least 30 minutes a day (51.7%); (2) lack of daily intake of vegetables and fruits or berries (52.8%); and
(3) family history of DM (74.7%).
Conclusion
The study found that one in every four college students in Quezon City is at risk of developing
T2DM in the next ten years.

Objective:
Recent advances in epigenetic studies continue to reveal novel mechanisms of gene regulation and control, however little is known on the role of epigenetics in sensorineural hearing loss (SNHL) in humans. We aimed to investigate the methylation patterns of two regions, one in RB1 and another in GJB2 in Filipino patients with SNHL compared to hearing control individuals.
Methods:
We investigated an RB1 promoter region that was previously identified as differentially methylated in children with SNHL and lead exposure. Additionally, we investigated a sequence in an enhancer-like region within GJB2 that contains four CpGs in close proximity. Bisulfite conversion was performed on salivary DNA samples from 15 children with SNHL and 45 unrelated ethnically-matched individuals. We then performed methylation-specific real-time PCR analysis (qMSP) using TaqMan® probes to determine percentage methylation of the two regions.
Results:
Using qMSP, both our cases and controls had zero methylation at the targeted GJB2 and RB1 regions.
Conclusion
Our study showed no changes in methylation at the selected CpG regions in RB1 and GJB2 in the two comparison groups with or without SNHL. This may be due to a lack of environmental exposures to these target regions. Other epigenetic marks may be present around these regions as well as those of other HL-associated genes.

Background/Aims:
Chagasic megacolon is caused by Trypanosoma cruzi, which promotes in several cases, irreversible segmental colonic dilation. This alteration is the major anatomic-clinical disorder, characterized by the enteric nervous system and muscle wall structural damage. Herein, we investigate how T. cruzi-induced progressive colonic structural changes modulate the colonic contractile pattern activity.
Methods:
We developed a murine model of T. cruzi-infection that reproduced long-term modifications of the enlarged colon. We evaluated colonic and total intestinal transit time in animals. The patterns of motor response at several time intervals between the acute and chronic phases were evaluated using the organ bath assays. Enteric motor neurons were stimulated by electric field stimulation. The responses were analyzed in the presence of the nicotinic and muscarinic acetylcholine receptor antagonists. Western blot was performed to evaluate the expression of nicotinic and muscarinic receptors. The neurotransmitter expression was analyzed by real-time polymerase chain reaction.
Results:
In the chronic phase of infection, there was decreased intestinal motility associated with decreased amplitude and rhythmicity of intestinal contractility. Pharmacological tests suggested a defective response mediated by acetylcholine receptors. The contractile response induced by acetylcholine was decreased by atropine in the acute phase while the lack of its action in the chronic phase was associated with tissue damage, and decreased expression of choline acetyltransferase, nicotinic subunits of acetylcholine receptors, and neurotransmitters.
Conclusions
T. cruzi-induced damage of smooth muscles was accompanied by motility disorders such as decreased intestinal peristalsis and cholinergic system response impairment. This study allows integration of the natural history of Chagasic megacolon motility disorders and opens new perspectives for the design of effective therapeutic.

INTRODUCTION:
Stigmatizing attitudes are barriers to treatment of mental health disorders. The burden
of stigma has not been established locally. This study aimed to assess the stigma in the community by
determining the knowledge, attitudes and behaviors of barangay residents towards mental health and
persons with mental health illness.
METHODS:
A total of 422 participants were included using convenience sampling. Participants were given
self-administered questionnaires that consisted of the Mental Health Knowledge Schedule (MAKS),
Community Attitudes Towards the Mentally Ill (CAMI), and Reported and Intended Behavior Scale (RIBS)
tools. The mean scores and percentages were computed and compared across the sociodemographic data of the respondents.
RESULTS:
Knowledge levels were relatively high with a mean score of 26.63. Depression, stress, bipolar
disorder and drug addiction were recognized as mental illnesses by the majority of the participants.
Scores in the stigmatizing ideologies authoritarianism (3.07) and social restrictiveness (2.58) were low,
while the positive ideologies benevolence (3.76) and community health ideology (3.85) had higher scores. Participants were reluctant to work with mentally-ill people (3.18) but were willing to be friends with them (3.87).
CONCLUSION
This study concludes that the respondents were generally knowledgeable about mental health illness. There was a general acceptance and less stigmatizing attitude, and a willingness to interact with people with mental illness.

Philippine Journal of Ophthalmology 2013;38(1):13-20
Objectives:
To do report the incidence of capsular changes in Crystalens-implanted eyes and analyze the indications and outcomes of yag capsulotomy.
Methods:
We reviewed the records of 411 eyes of 258 patients implanted with the Crystalens IOL. Capsular change
indications for yag capsulotomy were posterior capsular opacification (PCO), lens tilt, and capsular striae. Eyes in
each indication were further subdivided into therapeutic yag (TY) and prophylactic yag (PY) groups. Outcomes
before and after yag capsulotomy were analyzed.
Results:
Ninety of 411 crystalens-implanted eyes (22%) had undergone yag capsulotomy. Sixty-one eyes had PCO,
12 had lens tilt, and 17 had striae. Twenty-seven eyes belonged to the therapeutic (TY) and 63 eyes to the prophylactic
(PY) yag subgroups. The mean interval between phacoemulsification and yag capsulotomy was 10 months. In the
TY PCO subgroup, uncorrected distance visual acuity (UDVA) changed from 20/40 pre-yag to 20/25 post-yag,
uncorrected near visual acuity (UNVA) from J3 to J2, manifest refraction spherical equivalent (MRSE) from -0.43D
to -0.2D. In the TY tilt subgroup, UDVA changed from 20/50 to 20/30, UNVA was unchanged at J2, and MRSE
from -1.21D to -0.89D. In the TY striae group, UDVA changed from 20/50 to 20/30, UNVA from J3 to J2, and
MRSE from 0.62D to -0.4D. In the PY PCO subgroup, UDVA was unchanged at 20/25, UNVA unchanged at J2,
and MRSE changed from -0.52D to -0.47D. In the PY tilt subgroup, UDVA changed from 20/25 to 20/20, UNVA
unchanged at J2, and MRSE changed from -0.87D to -0.45D. In the PY striae subgroup, UDVA was unchanged at
20/30, UNVA changed from J3 to J2, and MRSE changed from -0.62D to -0.7D.
Conclusion
Capsular changes occurred after Crystalens implantation that necessitated yag capsulotomy. Once
vision has deteriorated, a therapeutic yag treatment can help improve vision. If capsular changes have occurred but
vision has not deteriorated, a prophylactic yag capsulotomy can stabilize visual and refractive outcomes.
