BACKGROUND AND OBJECTIVES

The global pandemic caused by Coronavirus Disease 2019 (COVID-19) has affected millions, with growing evidence of the potential role of ocular tissues in viral transmission. At the time of writing, local data regarding the phenomenon was limited. This study investigated external ocular manifestations in patients with COVID-19 at a referral center in the Philippines, examined correlations between demographics, systemic manifestations, and laboratory results with ocular manifestations, and determined their timing relative to systemic symptoms.

METHODS

This single-center, descriptive cross-sectional study was carried out from December 8 to 18, 2020 at the adult COVID-19 wards of the Philippine General Hospital involving 72 participants. Data collection involved relevant clinical history taking and performing gross eye examination. The prevalence of ocular manifestations was described with 95% confidence intervals. Correlations between ocular manifestations and quantitative variables were analyzed with point-biserial correlation, and associations with qualitative variables were tested using chi-square or Fisher’s exact tests.

RESULTS

Among participants, 31.9% presented with ocular manifestations with foreign body sensation as the most prevalent ocular symptom (11.1%) and conjunctival hyperemia as the most prevalent ocular finding (19.4%). The median age of patients with ocular manifestations was 41 years old with a higher prevalence in the male population (73.9%, CI=95%, p=0.001). No significant correlation was observed between presence of external ocular manifestations and the different systemic and ocular co-morbidities as well as with COVID-19 clinical classification. Among those who experienced symptoms, majority (29.2%) of the patients experienced systemic symptoms prior to the onset of ocular symptoms. Ocular complaints may present as the sole manifestation (13.9%). Several laboratory parameters were measured and only temperature and AST levels showed a low positive correlation with the presence of ocular manifestations. 

CONCLUSION

Ocular manifestations occur in roughly one third of patients with COVID-19 based on this study population. With some individuals presenting with ocular signs or symptoms as the initial and sole manifestation, healthcare practitioners must exercise caution and remain vigilant in managing patients who present as such. At the time of writing, this is the first local study investigating the different external ocular manifestations in patients with COVID-19. There is a need to pursue more robust studies and conduct more local investigations which will guide both ophthalmologists and other practitioners in strengthening existing guidelines regarding precautionary practices, clinical diagnosis, and management of COVID-19 patients.

Bullous hemorrhagic dermatosis (BHD) is a rare cutaneous manifestation characterized by tense hemorrhagic bullae that appear at sites distant from low molecular weight heparin (LMWH) injections, typically within seven days of exposure. As of March 2022, only 94 cases have been reported. It most commonly affects elderly males with predisposing factors for thromboembolism, such as carcinoma, and usually involves the extremities.

This case highlights the importance of maintaining a high index of suspicion for bullous hemorrhagic dermatosis (BHD) in patients receiving low molecular weight heparin, even beyond the typical 7-day window and in demographics not commonly affected. Early recognition and prompt discontinuation of the offending agent, as demonstrated in this atypical presentation involving a Filipino elderly woman with multiple comorbidities and no malignancy, can lead to favorable outcomes. Clinicians should be aware of this rare but reversible complication to avoid misdiagnosis and ensure appropriate management.

OBJECTIVES

In Asia, younger individuals (below age 45) are diagnosed to have type 2 diabetes with increased rates of obesity defined by lower BMI yet with greater visceral adiposity (waist circumference and waisthip ratios). The prevalence data on type 1 diabetes is not well established, considered to be low, but is seen to be increasing as well. This changing phenotype therefore, presents a clinical dilemma in terms of correctly classifying diabetes and deciding on the consequent appropriate treatment. Distinguishing type 1 from type 2 diabetes has become more difficult with type 2 diabetes dramatically increasing in young adults and children. This study aims to define the characteristics of diabetes among young adults in the Philippines to provide a basis for appropriate management amidst changes in diabetes phenotypes seen globally.

METHODS

In this cross-sectional analytic study, we characterized the demographic, metabolic, and autoimmune features of diabetes among young adult Filipinos aged 18 to 45 years old consulting at a tertiary referral center in Manila, Philippines. Baseline serum A1c, FBS, 75-g oral glucose tolerance test, insulin, serum C-peptide, insulin autoantibodies, leptin, adiponectin, lipid profile, and thyroid function tests were obtained from the participants and analyzed. The homeostasis model assessment (HOMA) was used to estimate the insulin sensitivity.

RESULTS

A total of 348 patients with diabetes were included, with females comprising two-thirds of the participants. The mean age at diagnosis of diabetes was 35.9±7.22 years. The mean BMI was 28.12 kg/m2, with median waist to hip ratio (WHR) of 0·93. Metabolic syndrome was found in 60% of participants and 67.82% were obese by body mass index. The mean A1c was 9.07±2.52%. Good glucose control (A1c less than 7.0%) was seen in 23% of participants  while nearly half (48%) had HbA1c which was >9.0%. The median levels of fasting insulin and C-peptide were 12.62 (range 1.33–90.42) mIU/L and 0.78 ng/mL (range 0–16.2), respectively. 

Included participants were diagnosed with diabetes within a year and as such, majority did not have any micro- or macrovascular complications. The most common diabetes complication was sensory neuropathy detected by monofilament testing, which was found in 28% of participants, followed by non-proliferative diabetic retinopathy in 13%. A history of previous diabetic ketoacidosis was found in 10 patients (2.87%). Glutamic acid decarboxylase (GAD) and insulin auto-antibodies were found in 3.2% and 19.3% of participants, respectively. Approximately half (51.73%) of the participants were insulin resistant by HOMA-IR.

CONCLUSION

In contrast with Caucasians and other Asians, diabetes among young Filipino adults is associated with lower BMI but with a similarly high visceral adiposity as shown by an elevated WHR. Metabolic syndrome with insulin resistance as defined by a variety of indices is predominant. Type 1 diabetes with autoantibodies occur in only a small fraction of this population. Data derived from this work can provide a framework for cluster analysis towards personalized management specific to this population.

BACKGROUND

Drowning is a significant cause of accidental death worldwide, and forensic investigation plays an important role in determining the circumstances and causes of these deaths. Despite its importance, research in forensic investigations related to drowning remains fragmented and insufficiently characterized.

OBJECTIVE

This study aimed to examine trends and patterns in publications on forensic examinations related to drowning deaths. Specifically, it sought to identify research gaps, highlight key contributions, and determine major thematic areas in the field.

METHODS

A total of 116 articles published between 2014 and 2023 were retrieved from the PubMed database using search terms related to forensic science and drowning deaths. Bibliometric analysis was performed using VOSviewer (version 1.6.20) to identify research clusters, patterns of author collaboration, and keyword co-occurrence. Filtered data were exported in .txt format to facilitate analysis and visualization.

RESULTS

Visualization analysis identified seven thematic clusters. China had the highest number of publications on this topic. The Academy of Forensic Science in Shanghai was the most productive institution, while Fa Yi Xue Za Zhi had the highest number of publications. Lippmann J. was the most prolific author. The most frequently cited source received 180 citations. The three most commonly discussed topics were drowning, forensic pathology, and autopsy, while the most frequent terms overall were forensic pathology, autopsy, and people.

CONCLUSION

The findings indicate substantial initial research interest in forensic investigations of drowning. However, publication output during the study period showed a downward trend, with a decrease of 16.4%. This decline suggests a notable gap in the literature and highlights the need for further research in this field.

OBJECTIVE: Observational studies have shown inconsistent associations of loneliness or social isolation (SI) with ischemic heart disease (IHD), with unknown mediators. METHODS: Using data from genome-wide association studies of predominantly European ancestry, we performed a bidirectional two-sample Mendelian Randomization (MR) study to estimate causal effects of loneliness ( N = 487,647) and SI traits on IHD ( N = 184,305). SI traits included whether individuals lived alone, participated in various types of social activities, and how often they had contact with friends or family ( N = 459,830 to 461,369). A network MR study was conducted to evaluate the mediating roles of 20 candidate mediators, including metabolic, behavioral and psychological factors. RESULTS: Loneliness increased IHD risk ( OR= 2.129; 95% confidence interval [ CI]: 1.380 to 3.285), mediated by body fat percentage, waist-hip ratio, total cholesterol, and low-density lipoprotein cholesterol. For SI traits, only fewer social activities increased IHD risk ( OR= 1.815; 95% CI: 1.189 to 2.772), mediated by hypertension, high-density lipoprotein cholesterol, triglycerides, fasting insulin, and smoking cessation. No reverse causality of IHD with loneliness and SI was found. CONCLUSION These findings suggested more attention should be paid to individuals who feel lonely and have fewer social activities to prevent IHD, with several mediators as prioritized targets for intervention.

OBJECTIVE

This seven-year, two-center retrospective cross-sectional study aimed to describe the demographic, clinical characteristics and surgical indications of patients managed with open or laparoscopic cholecystectomy in the pediatric age group, and determine these variables’ associations with patient outcomes.

METHODS

Records of all patients less than 19 years old who underwent laparoscopic or open cholecystectomy at Jose R. Reyes Memorial Medical Center (JRRMMC) and National Children’s Hospital (NCH) from January 2015 to December 2021 were reviewed. The gathered data were organized, described and analyzed using univariate and multivariate statistics.

RESULTS

A total of 32 patients underwent open or laparoscopic cholecystectomy at the two institutions. Majority were female (78.1%). The diagnoses included chronic calculous cholecystitis (62.5%), acute calculous cholecystitis (21.9%), choledocholithiasis (12.5%). One (3.1%) patient had empyema of the gallbladder. The 15 – 18 year age group made up 78.1%, with the rest (21.9%) from the 10 – 14 year age group. By BMI percentile, 62.5% were normal, 15.6% were overweight, and 12.5% were obese. Most patients across all conditions (96.9%) had no known hemolytic disorder. Underweight patients (9.4% of the cohort) had statistically higher lengths of stay [F(3,28) = 3.444, p = .030]. No significant associations were found between the categorical outcomes (discharged well, morbidity, mortality) and patient variables (age group, sex, BMI percentile, presence of co-morbidities, symptoms, indication for surgery, operation done).

CONCLUSION

In pediatric patients undergoing laparoscopic or open cholecystectomy, BMI percentile is inversely related to the length of hospital stay.

INTRODUCTION: Obstructive sleep apnoea (OSA) is a serious but underdiagnosed condition. Demand for the gold standard diagnostic polysomnogram (PSG) far exceeds its availability. More efficient diagnostic methods are needed, even in tertiary settings. Machine learning (ML) models have strengths in disease prediction and early diagnosis. We explored the use of ML with oximetry, demographic and anthropometric data to diagnose OSA. METHODS: A total of 2,996 patients were included for modelling and divided into test and training sets. Seven commonly used supervised learning algorithms were trained with the data. Sensitivity (recall), specificity, positive predictive value (PPV) (precision), negative predictive value, area under the receiver operating characteristic curve (AUC) and F1 measure were reported for each model. RESULTS: In the best performing four-class model (neural network model predicting no, mild, moderate or severe OSA), a prediction of moderate and/or severe disease had a combined PPV of 94%; one out of 335 patients had no OSA and 19 had mild OSA. In the best performing two-class model (logistic regression model predicting no-mild vs. moderate-severe OSA), the PPV for moderate-severe OSA was 92%; two out of 350 patients had no OSA and 26 had mild OSA. CONCLUSION Our study showed that the prediction of moderate-severe OSA in a tertiary setting with an ML approach is a viable option to facilitate early identification of OSA. Prospective studies with home-based oximeters and analysis of other oximetry variables are the next steps towards formal implementation.

Objectives: This study described the clinical profile of patients with keratoconus at a single tertiary referral hospital. Methods: This was a single-center, retrospective, cross-sectional study that reviewed medical records of patients diagnosed with keratoconus from January 2015 to August 2022. Data on the clinical profile, intervention, and clinical outcomes were collected from the chart review. Results: Forty (40) patients (79 eyes) were included in the study. Majority (98%) had bilateral disease in which 22 (55.5%) were affected asymmetrically. The mean age was 21 years. Most patients (72.5%) were male. Blurring of vision was the chief complaint in all patients. Atopy was present in 23 patients (57.5%). History of vigorous eye rubbing was present in 31 (77.5%). The mean interval from onset of symptoms to consult was 46.4 ± 33.38 months. The mean pinhole corrected distance visual acuity was 0.47 ± 0.41 (Snellen equivalent of 20/59). The average spherical equivalent was -7.48D ± 6.99D. Corneal protrusion on slit-lamp biomicroscopy was seen in 78 eyes (98.7%). Other findings included Fleischer ring (53.2%), Vogt's striae (19.0%), and apical corneal scar (24.0%). Only one eye (1.3%) had no corneal findings. Thirty-nine eyes (49.3%) were classified as advancedsevere keratoconus. Rigid contact lens was planned for 60 eyes (75.9%). Sixty-two eyes (78.5%) were for collagen cross-linking. Deep anterior lamellar keratoplasty was planned in 10 eyes (12.7%) and penetrating keratoplasty in two eyes (2.5%). Conclusion Keratoconus at the Philippine General Hospital was most frequently seen in young males and asymmetrically affects both eyes. Patients consulted relatively late and presented with a more advanced stage of the disease. History of ocular allergy and eye rubbing were significant risk factors. Improving awareness of this condition must be emphasized to detect keratoconus earlier.

INTRODUCTION

Nurses handling the Tuberculosis Directly Observed Treatment Short Course (TB-DOTS) are crucial in implementing the National Tuberculosis Program (NTP), which faced challenges during COVID-19. Hence, this study aimed to explore and to understand the TB DOTS Nurses' lived experiences on implementing NTP amidst the COVID-19 pandemic.

METHODS

A descriptive phenomenology research design was used in this study among purposively selected 15 TB DOTS nurses during the pandemic, using in-depth interviews. Descriptive phenomenology was chosen to focus on capturing and describing the nurses' direct experiences. Data were manually transcribed into EXCEL software, coded, clustered, and thematized. Data were also collected from January to April 2023, following IATF Guidelines. Colaizzi's descriptive phenomenology method was employed for analysis, allowing the study to remain true to the participants' own words and perspectives.

RESULTS

This study revealed three major themes with associated subthemes anchored from the significant statements extracted from the participants' verbatims. The first theme, “Menace of Uncertainties,” echoed nurses’ fears of contracting the disease, struggles with implementing the NTP, and balancing patient care with personal well-being. Despite obstacles, nurses formed support systems and remained determined, leading to the emergence of the second theme, "Seeing Light in the Darkness." The third theme, "Establishing a Strong Foundation," outlined nurses' ideas for managing the NTP during a pandemic.

CONCLUSION

The study underscored the significant challenges TB DOTS nurses faced during the pandemic, including fear, uncertainty, and difficulty balancing personal well-being with patient care. Despite these obstacles, nurses demonstrated resilience, adaptability, and a commitment to their work. The findings underscored the importance of support systems, flexibility, and enhanced resources in managing TB cases during crises. These insights had direct implications for nursing practice, education, and research, while having emphasized the need for improved facilities, support mechanisms, and training to better equip nurses for future health emergencies.

In this study, we investigated how empathic neural responses unfold over time in different empathy networks when viewing same-race and other-race individuals in dynamic painful conditions. We recorded magnetoencephalography signals from Chinese adults when viewing video clips showing a dynamic painful (or non-painful) stimulation to Asian and White models' faces to trigger painful (or neutral) expressions. We found that perceived dynamic pain in Asian models modulated neural activities in the visual cortex at 100 ms-200 ms, in the orbitofrontal and subgenual anterior cingulate cortices at 150 ms-200 ms, in the anterior cingulate cortex around 250 ms-350 ms, and in the temporoparietal junction and middle temporal gyrus around 600 ms after video onset. Perceived dynamic pain in White models modulated activities in the visual, anterior cingulate, and primary sensory cortices after 500 ms. Our findings unraveled earlier dynamic activities in multiple neural circuits in response to same-race (vs other-race) individuals in dynamic painful situations.
