This is the case of a 62-year-old male with prior modified Bentall’s procedure using a 23-mm bioprosthetic valve last 2013 who came in with progressive heart failure symptoms. On physical examination, vital signs are stable. Physical exam revealed rhonchi on both lung fields and irregular rhythm with a grade 3 systolic ejection murmur at the aortic area. A 2-dimensional transthoracic echocardiogram showed an ejection fraction of 25%, aortic valve area of 1.0 cm2 and mean gradient of 21 mmHg consistent with severe low-flow, low-gradient aortic stenosis (AS). Options for re-do surgical aortic valve replacement (SAVR) were discussed. Since the patient was deemed high risk for another surgery, the option for transcatheter aortic valve in surgical aortic valve (TAV-in-SAV) was considered. The patient underwent successful TAV-in-SAV using a 26-mm self-expanding bioprosthetic valve. Post-procedure, there was significant improvement of functional capacity from class IV to class I.

eToyBox is a learning management system for preschool teachers to improve their health literacy, which ultimately aims
to improve children’s obesity-related behaviour. As part of the development process of eToyBox, assessment on digital
literacy, acceptance of digitization of education materials, and perceived barriers in adopting online learning is needed.
Fifty-four preschool teachers under the Community Development Department (KEMAS) in Kuala Lumpur, Selangor,
and Sarawak, who participated in ToyBox Study Malaysia intervention in 2018, took part in this cross-sectional study.
An online self-administered questionnaire was used to assess sociodemographic background, use of communication
tools and media, and teacher’s views on adapting the ToyBox modules to digital education materials. Respondents were
contacted, and questionnaire link was shared through WhatsApp messages. Most participants (74.0%) were Malay
females aged 31 to 40 years old. Most participants had internet access (94.4%) and owned at least a smart phone,
laptop or tablet (94.4%). Participants perceived their computer skills to be average (75.0%). Majority of respondents
(65.0%) reported advanced and higher abilities in word processing and email, but only 22.0% in spreadsheet skills. The
main barrier to accessing online material was unstable internet connection (74.1%). Most respondents (90.0%) agree
that adapting effective modules to online learning will be beneficial for professional development and teaching practices.
In conclusion, most participants supported digitizing Toybox Study Malaysia educational content and were comfortable
72
with its implementation via an online learning platform. The findings from this study can advise future development of
online learning materials for preschool teachers in Malaysia.

Rib fractures account for a significant number of emergency department visits each year. A patient’s disposition often depends on the severity of rib fractures, comorbidities, and ability to achieve adequate analgesia. We present a 44-year-old male patient with severe pain secondary to rib fractures. The initial disposition was to admit for pain control. However, upon performing a serratus anterior plane block, patient was functionally appropriate for discharge with proper return precautions. Serratus anterior plane block is within the skillset of the emergency physician and can be used to achieve analgesia for rib fractures without the sedative and respiratory depressive effects associated with opioids.

Objective:
To evaluate the accuracy of a one-piece bracket jig system fabricated using computer-aided design and manufacturing (CAD/CAM) by employing three-dimensional (3D) digital superimposition.
Methods:
This in vitro study included 226 anterior teeth selected from 20 patients undergoing orthodontic treatment. Bracket position errors from each of the 40 arches were analyzed quantitatively via 3D digital superimposition (best-fit algorithm) of the virtual bracket and actual bracket after indirect bonding, after accounting for possible variables that may affect accuracy, such as crowding and presence of the resin base.
Results:
The device could transfer the bracket accurately to the desired position of the patient’s dentition within a clinically acceptable range of ± 0.05 mm and 2.0° for linear and angular measurements, respectively. The average linear measurements ranged from 0.029 to 0.101 mm. Among the angular measurements, rotation values showed the least deviation and ranged from 0.396° to 0.623°. Directional bias was pronounced in the vertical direction, and many brackets were bonded toward the occlusal surface. However, no statistical difference was found for the three angular measurement values (torque, angulation, and rotation) in any of the groups classified according to crowding. When the teeth were moderately crowded, the mesio-distal, bucco-lingual, and rotation measurement values were affected by the presence of the resin base.
Conclusions
The characteristics of the CAD/CAM one-piece jig system were demonstrated according to the influencing factors, and the transfer accuracy was verified to be within a clinically acceptable level for the indirect bracket bonding of anterior teeth.

Objectives:
The aims of this study were to examine the prevalence of overweight/obesity and to explore sex differences in body weight perceptions and correlates of weight gain among Black students at 2 historically Black colleges and universities (HBCUs) in the USA.
Methods:
Participants completed a paper-based survey, and their height and weight weremeasured (67% completion rate).
Results:
The overweight and obesity rates were 33.8% and 26.9%, respectively. More females than males accurately assessed their weight (p < 0.05). Body weight underestimation was associated with male sex, excellent/very good perceived overall health, and not being informed by a doctor of having overweight or obesity (p <0.01). Higher odds of ≥5% weight gain were related to female sex, living on campus, and not being informed by a doctor of having overweight or obesity (p <0.05).
Conclusion
Given the high overweight and obesity rates among Black students, HBCUs in the USA should develop intervention strategies for the prevention and management of overweight and obesity. College health educators at HBCUs need to provide regular check-ups or health screenings that help male students perceive their weight accurately and prevent weight underestimation. It is important for HBCUs to monitor and address weight gain among Black students as early as possible.

Objective:
To identify the most favorable sites that optimize the initial stability and survival rate of orthodontic mini-implants, this study measured hard and soft tissue thicknesses in the median and paramedian regions of the palate using cone-beam computed tomography (CBCT) and determined possible sexand age-related differences in these thicknesses.
Methods:
The study sample comprised CBCT images of 189 healthy subjects. The sample was divided into four groups according to age. A grid area was set for the measurement of hard and soft tissue thicknesses in the palate. Vertical lines were marked at intervals of 0, 1.5, and 3.0 mm lateral to the midpalatal suture, while horizontal lines were marked at 2-mm intervals up to 24 mm from the posterior margin of the incisive foramen. Measurements were made at 65 points of intersection between the horizontal and vertical lines.
Results:
The palatal hard tissue thickness decreased from the anterior to the posterior region, with a decrease in the medial-to-lateral direction in the middle and posterior regions. While the soft tissue was rather thick around the lateral aspects of the palatal arch, it formed a constant layer that was only 1–2-mm thick throughout the palate. Statistically significant differences were observed according to sex and age.
Conclusions
The anterolateral palate as well as the midpalatal suture seem to be the most favorable sites for insertion of orthodontic mini-implants. The thickness of the palate differed by age and sex; these differences should be considered while planning the placement of orthodontic mini-implants.

Philippine Journal of Ophthalmology 2012;37(2):97-103
Objective:
To determine the efficacy of the Wong incision in providing wound seal compared to stromal wall
hydration in clear cornea phacoemulsification in cadaveric porcine eyes.
Method:
This was an in vitro comparative experimental study using ten porcine eyes. All eyes were randomly
assigned to the stromal wall hydration (control) or the Wong incision group (experimental). A side port was made
and the anterior chamber formed with viscoelastic device. The main incision was made 180 degrees away. In the
experimental group, a Wong incision was made first anterior to the main incision. Phacoemulsification surgery
with IOL insertion was simulated. The main incision was sealed by hydration. The anterior chamber (AC) was
infused with balanced salt solution (BSS) through an AC maintainer and leakage of fluid from the main incision
was assessed. Samples from the AC were taken before and after tryphan blue drip and were sent for analysis
by UV spectrophotometry. Trypan blue was dripped over the main incision and the whole eyeball was sent for
histopathology.
Results:
There was a significant increase in density from the pre-dye to the post-dye AC samples of the control
(0.0052 to 0.0074, p=0.01) and the experimental groups (0.0076 to 0.0094, p=0.02), although the final samples
showed an optical density comparable to pure BSS, indicating that there was no significant amount of trypan blue
detected in both groups. On histology, trypan blue staining was not seen in the incision tracts of both groups.
After infusing the AC with BSS, there was outward wound leakage in all eyes of the control group and none in the
experimental group.
Conclusion
The Wong incision was as effective as the lateral stromal wall hydration in preventing fluid influx.
Furthermore, the Wong incision showed a more stable wound seal against outward wound leakage in an in-vitro
porcine model of clear corneal phacoemulsification.
