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.

BACKGROUND

Non-Alcoholic Fatty Liver Disease (NAFLD) is common in Type 2 Diabetes Mellitus (T2DM). The FIB-4 index is one of the most-studied non-invasive biomarkers that combines age and laboratory parameters (platelet count, alanine-and aspartate- aminotransferase) to evaluate underlying hepatic fibrosis. This study aims to determine the diagnostic value of Fibrosis-4 (FIB-4) index scoring in screening for non-alcoholic fatty liver disease in patients with type 2 diabetes mellitus, which is a high-risk population in development of advance fibrosis.

A single center, analytical cross-sectional study was conducted among adult T2DM patients with and without NAFLD seen at the Out-Patient Department (OPD) and those with NAFLD enrolled under the Liver Disease Databank of the Liver Disease and Transplant Center in collaboration with Research and Biotechnology Division at St. Luke’s Medical Center, Quezon City. Medical history was obtained by reviewing charts of eligible patients using data collection form. Liver ultrasound was used as the reference standard in the diagnosis of NAFLD. The FIB-4 index was calculated with this formula: age (years) x AST (U/L)/(platelets (10^9/L) x ALT (U/L)^1/2.

A total of 305 adult patients with type 2 diabetes mellitus were included in the study. The prevalence of non-alcoholic fatty liver disease based on ultrasound among diabetic patients is 76.07%. The median age (p = 0.0204), AST (p < 0.00001), ALT (p < 0.00001) were significantly higher in patients with NAFLD than those without. Platelet count (p = 0.0002) was significantly lower in patients with NAFLD than those without. The proportion of patients with low platelet count, high AST and high ALT were significantly higher in patients with NALFD than those without. In this study, the FIB-4 index cutoff score for screening of NAFLD is ≥0.76, which has an accuracy of 66.23%, sensitivity of 75%, specificity of 38.3%, PPV of 79.46% and NPV of 32.56% in detecting fatty liver.

A FIB-4 index value of ≥0.76 has an acceptable sensitivity for screening NAFLD even in the absence of fibrosis among patients with T2DM. However, due to its low specificity, additional tests to establish NAFLD diagnosis may be required.

INTRODUCTION

Demyelinating central nervous system (CNS) disorders such as transverse myelitis (TM) and multiple sclerosis (MS) have been reported with mRNA Covid-19 vaccine. Some cases were relapses of a pre-existing condition but de novo and initial presentation of MS after BNT162b2 COVID-19 mRNA vaccine has very rarely been documented.

We report a 72-year-old female, right-handed, Filipina, with a one-month history of bilateral lower extremity weakness which occurred 7 days after she received her first booster dose of BNT162b2 mRNA vaccine. This was later accompanied by fecal and urinary incontinence. On examination, she had motor deficit below L1 myotome manifesting with loss of hip flexion, knee extension, dorsiflexion, and plantar flexion. There was also sensory deficit below T10 level with relative 80% sensation of vibratio, proprioception, light touch and complete loss of pain and temperature sensation. The initial impression was Transverse Myelitis which may be related to a post-vaccination state. Spinal magnetic resonance imaging (MRI) revealed long segment enhancing T2W hyperintense lesion at T2 to T7. Cranial MRI revealed ovoid areas of heterogeneous, predominantly T2/FLAIR hyperintense signals exhibiting restricted diffusion in the periventricular white matter of the fronto-parietal lobes. Cerebrospinal fluid (CSF) analysis was negative for infectious causes such as tuberculosis but with high levels of CSF immunoglobulin G. She was then diagnosed to have Multiple Sclerosis (MS) and was treated with high dose oral prednisone. However, there was no improvement in neurological deficits on follow-up.

This case adds to the reported rare cases of initial presentation of MS occurring after vaccination for COVID-19 and the first reported case in the Philippines. Early recognition and prompt treatment is important to improve outcomes.

OBJECTIVE

This study determined the diagnostic accuracies of Growth and Retinopathy of Prematurity (GROP) criteria and a novel modified G-ROP criteria on identifying retinopathy of prematurity (ROP) in infants referred for screening at a tertiary hospital.

This was a single-center, cross-sectional, retrospective study. Medical records of infants referred for ROP screening from January 2012 to December 2021 were reviewed. Infants were labelled as “requiring ROP examination” if they met the 2020 Philippine Academy of Ophthalmology – ROP Working Group (PAO-ROPWG) screening consensus, G-ROP, or modified G-ROP criteria. We compared the accuracy of each criterion in predicting prethreshold ROP, evaluating sensitivity, specificity, and predictive values, as well as percentage of low-risk infants. Statistical analysis used Chi-square tests and one-way ANOVA with post hoc testing.

Of the 873 infants, 162 infants (18.6%) were noted to have ROP of any stage. Type 1 ROP developed in 15.4%, and type 2 ROP in 16.7%. The 2020 PAO-ROPWG consensus had 100% sensitivity (95% CI: 86.3%- 100%) in detecting type 1 and 2 ROP while 323 infants (37%) were low-risk. G-ROP criteria had 100% (95% CI: 86.3%-100%) sensitivity and 79.2% (95% CI: 76.4%-81.9%) specificity in predicting type 1 ROP, and 88.89% (95% CI: 70.84%-97.65%) sensitivity and 79.1% (95% CI: 76.2%-81.8%) specificity in predicting type 2 ROP, while 672 infants (77%) were classified as low-risk. Modified G-ROP criteria had a 100% (95% CI: 86.3%-100%) sensitivity in predicting type 1 and 2 ROP, 54.9% (95% CI: 51.5%-58.3%) and 55.1% (95% CI: 51.7%-58.5%) specificity in predicting type 1 and type 2 ROP, respectively, while 472 infants (54%) were classified as low-risk.

G-ROP and modified G-ROP criteria showed high sensitivity and better specificity compared to the 2020 PAO-ROPWG consensus. Their stricter criteria for gestational age and birth weight likely enhanced specificity. Further research is needed to confirm these findings in a broader population.

OBJECTIVE

This study compared the demographics, clinical profile, treatment, and outcomes of retinoblastoma patients seen at medical institutions in the Philippines between two time periods: 2010 to 2015 and 2016 to 2020.

This was a multicenter, analytical, cohort study using review of medical charts and databases of retinoblastoma patients seen in 11 medical institutions from 2010 to 2020.

There were 636 patients (821 eyes) included in this study: 330 patients were seen in 2010 to 2015 while 306 in 2016 to 2020. More cases per annum were seen in the latter timeline. The number of patients with unilateral disease was not significantly different between the two time periods (p=0.51). Age at onset of symptom, age at initial consultation, and delay in consult were also not significantly different between the two time periods (p > 0.05). Patients had significantly different distributions of intraocular grades (p < 0.0001) and systemic staging (p < 0.0001) between the two time periods. Enucleation was the most common surgical treatment performed in both timelines. There was significant difference in the status of patients based on the need for systemic chemotherapy (p < 0.01). There was significant difference in outcome between the two time periods, including the proportions of living and deceased patients.

This study compared the most comprehensive data on retinoblastoma patients in the country. There was no improvement in early health seeking behavior based on similar age at initial consult and delay in consult. Enucleation remained the most common treatment mode as opposed to chemotherapy due to similar percentage of patients with unilateral disease, an indication for enucleation rather than chemotherapy.

Introduction: We present a patient with long-standing uncontrolled type 2 diabetes mellitus (T2 DM) who developed sudden onset of choreiform movement, which rapidly resolved after insulin therapy and haloperidol. Case Description: A 53-year-old Filipino male, with T2DM and hypertension for more than 10 years, presented with sudden onset of hyperkinetic, involuntary, non-patterned, continuous movements of the left upper and lower extremities. Investigations revealed severe hyperglycemia without acidemia and ketonuria. Cranial computed tomography scan showed hyperdensity on the right caudate and lentiform nuclei. On cranial magnetic resonance imaging, there was T1- weighted hyperintense and T2 - weighted hypointense signal involving the right putamen, globus pallidus and caudate. Cranial magnetic resonance angiography showed stenosis on the cavernous segment of the right internal carotid artery (ICA), left ICA and middle cerebral artery (MCA) junction, the A1 segment of the left anterior communicating artery and proximal P2 segments of the bilateral posterior cerebral arteries. The patient was managed with a basal-bolus insulin regimen to control the blood glucose and haloperidol to manage the extrapyramidal symptoms. Consequently, there was complete resolution of the involuntary movements. Conclusion This case illustrates the importance of a systematic approach to movement disorders and early recognition of this rare diabetes complication known as chorea hyperglycemia basal ganglia syndrome or diabetic striatopathy.

BACKGROUND

According to the World Health Organization, in 2016, there were more than 1.9 billion adults who were overweight. Of these, over 650 million were obese. Physical inactivity is one of the major risk factors for several non-communicable diseases. Healthcare workers who have direct contact with patients often influence their behaviors. However, health care workers who educate their patients but they themselves do not practice what they recommend, may be one of the barriers that can affect patient education and influence.

This research paper aimed to investigate the motivation to participate in physical activity among healthcare workers and to determine the association between the profile of respondents with the different types of motivation.

There was a total of 250 randomly selected respondents who were included in the study. Data were gathered through a self-administered questionnaire utilizing the International Physical Activity Questionnaire-Short Form (IPAQ-SF) and the Behavioral Regulation in Exercise Questionnaire (BREQ-2). Descriptive statistics was used to summarize sociodemographic information, physical activity levels and BREQ-2 profiles. T-test was used to analyze differences in gender while analysis of variance (ANOVA) was used for levels of physical activity and professional category.

Female healthcare professionals have a higher average in amotivation (mean=0.56) while males have a higher average in intrinsic (mean=2.82) motivation. Nurses and ancillary services have higher average amotivation scores than physicians.

Health care workers who have high classification in physical activity have the highest average scores in terms of relative autonomy index, introjected, identified, and intrinsic scores. This demonstrates a positive association between motivation from internal regulation and increased physical activity.
