BACKGROUND

Due to the COVID-19 outbreak, schools had to switch online. The sudden transition to blended teaching and learning (BTL) poses challenges for students and teachers, especially for health science programs that require hands-on practical experience. The validity, reliability, and responsiveness of these self-report questionnaires (SRQs) should be established to ensure the accuracy of the results as intended by the SRQ.

This study critically appraised, compared, and summarized the psychometric properties of SRQ evaluating BTL among health science university students. This review determined the SRQ’s reliability, internal consistency, various forms of validity (content, criterion, construct), and responsiveness.

Following a 10-step procedure based on COSMIN guidelines, we conducted a systematic review of SRQs used by health science university students to evaluate blended teaching and learning. Studies were eligible if they reported psychometric properties of SRQs related to blended learning among university health science students; exclusions included studies focusing on perceptions, attitudes, self-efficacy, and satisfaction, as well as articles such as biographies, editorials, and conference materials. Searches covered multiple electronic databases until April 26, 2023, including PubMed, EMBASE, Web of Science, MEDLINE (OVID), PsycInfo, CINAHL, EBSCOHOST, ERIC, Scopus, Science Direct, Google Scholar, JSTOR, Acta Medica Philippina, Philippine Journal of Health Research and Development, and HERDIN, managed through Zotero. Two independent reviewers performed database searches, title and abstract screening, and full-text evaluations, with a third reviewer resolving any disputes. The COSMIN Risk of Bias Checklist was employed to evaluate included studies on the development and various measurement properties of SRQs. The reviewers assessed SRQ standards, including validity, reliability, internal consistency, measurement error, responsiveness, interpretability, and feasibility. Data extraction and result tabulation were independently completed, with content comparison by two health education experts. This evaluation categorized the SRQs into three quality and validity levels.

The study examined five articles; four were rated as 'doubtful' and one as 'inadequate' in the overall development of SRQ. All four 'doubtful' studies demonstrated questionable content validity when university students were asked about the questionnaire's relevance, comprehensiveness, and comprehensibility. Only half of these studies achieved an 'adequate' rating for content validity based on expert opinions on relevance and comprehensiveness. All but one study scored from 'very good' to 'adequate' in structural validity. Three out of the four studies scored a very good rating for internal consistency, while one was deemed 'inadequate' in internal consistency, cross-cultural validity, and reliability. Three out of four studies scored 'very good' on construct validity, but all overlooked criterion validity and responsiveness. Conducted in various locations, including Australia, Romania, Turkey, and Taiwan, these studies highlighted both common characteristics and limitations in questionnaire development according to the COSMIN guidelines. Four studies were deemed reliable and valid for BTL constructs (Category A); Wu et al. requires further validation (Category B). Study limitations included heterogeneity in populations, settings, and questionnaire versions, potential subjective bias in SRQ content comparison, and the evolving nature of SRQs in blended learning contexts.

The systematic review reports the development and evaluation of SRQs for BTL while identifying gaps in their applicability to health science programs. The Blended Learning Scale (BLS) of Lazar et al. and the Blended Learning Questionnaire (BLQ) of Ballouk et al. showed an ‘adequate' rating for content validity. BLS revealed very good structural validity, internal consistency, and adequate content validation. Although the BLQ lacked Confirmatory Factor Analysis, it yielded valuable constructs for evaluating health sciences students' experiences in BTL. Both tools require improvements on recall period, completion time, interpretability, and feasibility. The review underscores the necessity for cont inuous assessment and enhancement of such instruments in BTL, advocating a rigorous scale development process. Furthermore, it encourages the customization of teaching and learning evaluation tools to suit specific institutional contexts while promoting further validation of these questionnaires across different populations in future research.

OBJECTIVE

To compare the frequency and severity of color vision defects between diabetes mellitus (DM) patients without retinopathy and those with mild non-proliferative diabetic retinopathy (NPDR), and to evaluate the relationship between these color vision defects and capillary blood glucose (CBG) levels.

This was a cross-sectional, hospital-based study conducted over a seven-month period at the Ophthalmology Outpatient Department of Cardinal Santos Medical Center. Thirty-five (35) DM patients (70 eyes) aged 50 to 75 years with best-corrected visual acuity of ≥20/50 and no more than mild NPDR were included. Patients with moderate or severe NPDR, macular edema, optic nerve pathology, or significant cataracts were excluded. All participants underwent visual acuity testing, fundus examination, and color vision assessment using the Ishihara pseudoisochromatic plates and Farnsworth D-15 tests conducted under standardized lighting conditions. CBG was measured using the finger-prick method. Main outcome measures included the proportion and type of color vision defects, their association with DR classification, and CBG levels. Statistical analyses included descriptive statistics, the Fisher exact test, the Mann-Whitney U test for the Farnsworth D-15 Color Confusion Index (CCI), and Spearman correlation between CBG and CCI.

Tritan-type defects were the most common, accounting for 36.2%. Color vision defects were observed in 91.3% (64 eyes) of patients with no DR, while defects were seen in all eyes (100%) with mild NPDR (5 eyes). However, this difference was not statistically significant (p = 1.000). There was no significant correlation between CBG levels and color vision scores. Mean CCI scores were similar between groups (p = 0.394), indicating no substantial difference in defect severity.

Color vision defects may be more prevalent in early NPDR compared to no DR, but this difference was not significant in this sample. No correlation was found between CBG levels and color vision performance. Color vision testing may serve as a useful adjunctive screening tool for early diabetic retinal changes; however, further studies with larger sample sizes are necessary.

Introduction: Atopic dermatitis (AD) is a complex disease with an interplay of genetic and environmental factors. In the United States, AD affects 10.7% of children andyc 7.2% of adults. Similarly in the Philippines, the prevalence of AD is 12.7% in the under 18 population, and 2% in the over 18 population. While AD affects all ages, the burden of the disease is greater in the pediatric population. The pathogenesis of AD is multifactorial. Variations in genes responsible for epidermal barrier function, keratinocyte terminal differentiation, and the innate and adaptive immune responses have been linked to AD. A null mutation involving the filaggrin gene is the strongest known risk factor for AD. This mutation results in a loss of filaggrin (FLG) protein by at least 50%. Filaggrin breakdown products form part of the natural moisturizing factor (NMF) of the skin, which is essential in skin hydration. A decrease in NMF and an increase in transepidermal water loss (TEWL) are observed in AD patients with FLG mutation. The defective barrier in AD patients decreases skin defenses against irritation and allergen penetration. Exposure to certain environmental chemicals like formaldehyde may worsen this barrier. This may lead to increased skin permeability to aeroallergens that leads to dermatitis in sensitized patients. Barrier defects may also play a role in epicutaneous sensitization and the subsequent development of other atopic conditions, such as bronchial asthma and allergic rhinitis. The Philippine Dermatological Society (PDS) consensus on AD aims to provide a comprehensive guideline and evidence-based recommendations in the management of this condition, with consideration of cultural factors that are often encountered in the Philippine setting. These guidelines are intended to provide practitioners with an overview of the holistic approach in the management of AD, ameliorating the negative effects of the disease and improving overall quality of life.. Methodology: A group of 21 board-certified dermatologists from the Philippine Dermatological Society (PDS) convened to discuss aspects in the clinical management of AD. Database and literature search included the full-text articles of observational studies, randomized controlled clinical trials, and observational studies using the Cochrane library, PubMed, Hardin (for Philippine based studies) as well as data from the PDS health information system. The terms used in combinations from the literature included “atopic dermatitis”, “atopic eczema”, “emollients”, “topical corticosteroids”, “topical calcineurin inhibitors”, “anti-histamines” and “phototherapy”. A total of fifty (50) full text articles were reviewed and found applicable for the scope of the study. Articles were assessed using the modified Jadad scale, with score interpretations as follows: (5- excellent, 3- good, 1– poor). Consensus guidelines for AD from within and outside of the region were also reviewed, from the 2013 Asia-Pacific guidelines, 2014 Taiwanese Dermatological Association consensus, 2016 guidelines in the management of AD in Singapore, 2014 American Academy of Dermatology guidelines, and the 2020 Japanese guidelines for AD. From the literature review, proposed consensus statements were developed, and a Delphi survey was conducted over two separate virtual meetings. Individual dermatologists provided Likert Scoring (1- strongly disagree to 5- strongly agree) based on consensus statements. A consensus was deemed reached at mean scores of > 4.00, a near consensus at > 3.5, and no consensus at <3.5. Summary: AD is a chronic relapsing condition with a significant burden of disease, most commonly affecting the pediatric population. The PDS AD Consensus Guidelines summarizes the standards of therapy and the therapeutic ladder in the management of AD based on published clinical trials and literature review. While these modalities remain the cornerstone of therapy, an individualized approach is the key to the holistic management of an AD patient. Knowledge and awareness of frequently associated conditions, whether in the realm of food allergies, contact allergies, or secondary infections, is paramount. In addition to the standard therapeutic armamentarium, the physician must also consider cultural practices and be knowledgeable of alternative therapeutic options. Referral to a specialist is recommended for recalcitrant cases of AD, or when initiation of systemic immunosuppressive agents, phototherapy, or biologic agents is contemplated.

BACKGROUND: A reliable and socially validated definition of recovery in schizophrenia is essential to decrease stigma associated with the illness. This study aimed to define recovery in schizophrenia in the Philippine context, determine its specific elements, and describe methods of assessment in clinical practice. METHODS: We invited a group of purposively selected Filipino psychiatrists to participate in six simultaneous roundtable discussions to gather their opinions and perspectives on recovery in schizophrenia. Transcripts of the discussions were then subjected to framework analysis. RESULTS AND CONCLUSION Most Filipino psychiatrists were of the considered opinion that recovery in schizophrenia is possible, and their vision of a recovered patient resembles a combination of psychological and medical models. The mini-FROGS tool was deemed generally applicable in the Philippine setting except for self-esteem and sense of independence primarily because it is difficult to evaluate. The SWN was received with mixed reactions among the psychiatrists. Spirituality as an element of recovery and the family-oriented culture of the Filipinos were emphasized as important considerations in assessing patients. Other suggestions were given to tailor-fit these tools to the Philippine context.

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.
