In the field of medicine and cardiology, there is perhaps no other condition or situation that stimulates an adrenalin rush for the healthcare team than a patient presenting with wide QRS complex tachycardia. These cases may be potentially fatal and are usually associated with worse outcomes. While the real-world experience in the evaluation and management of these cases can be chaotic situations, a careful, systematic and organized scrutiny of the electrocardiographic tracing is key to obtaining a correct diagnosis and proceeding with the right therapeutic management. An understanding of the physiological mechanisms of arrhythmia, the appreciation of scientific basis for electrocardiographic features and recognition of different criteria for diagnosis provides endless opportunities and “teachable moments” in medicine. For both learners and teachers, the academic discussion of these points and features can be an exciting journey and electrifyingly educational experience. This article provides a simplified yet beautifully complicated approach to diagnosing wide complex tachycardia.

INTRODUCTION

Strength is a key modifiable risk factor for hamstring strains with significant differences between injured and non-injured sides in the lengthened position. Ensuring the test-retest reliability of measurement protocols ensures consistent injury prevention, rehabilitation and return-to-sport planning.

To evaluate the test-retest reliability of hamstring strength protocols in both standardized and lengthened positions among healthy adults.

Test-retest reliability study.

Human Performance Laboratory, Fr. Roque Ruano building, University of Santo Tomas, Espana Manila.

Ten healthy adults (six males and four females; mean age: 26.5 ± 4.03 years).

Absolute and relative peak torque for concentric and eccentric hamstring and quadriceps were measured at 60°/sec, 180°/sec and 240°/sec in the standardized position (hip and knee flexed at 90°). In the lengthened position (hip flexed at 85° and knee at 30°), isometric knee flexion and peak torque for concentric and eccentric hamstring and quadriceps were assessed at 60°/sec and 180°/sec. Strength ratios were calculated for both positions.

Intraclass Correlation Coefficient (ICC) values demonstrated good to excellent reliability for peak torque measurements, with higher reliability in the standardized position (ICC 0.83-0.94) than in the lengthened position (ICC 0.79-0.96). Conventional and functional ratios varied, with lower ICCs for the right leg in the standardized position (ICC 0.32-0.92) and moderate to good reliability in the lengthened position (ICC 0.63-0.87).

Standardized and lengthened positions provide reliable assessments of absolute and relative peak torque for hamstring and quadriceps muscles during concentric and eccentric contractions across all speeds, including conventional and functional strength ratios.

INTRODUCTION

Administration of antenatal corticosteroids (ACS) between 24 and 36 weeks of gestation is recommended to pregnant women at risk of preterm delivery to decrease the risk of respiratory distress syndrome, intra-ventricular hemorrhage and neonatal death. However, it may worsen glycemic profile primarily in those with gestational diabetes mellitus (GDM).

To determine the effects of ACS on maternal glycemia in Filipino women with GDM and to analyze the factors associated with insulin use or increased insulin requirement.

A retrospective study of the medical records of Filipino women with GDM who were admitted and received ACS treatment (betamethasone) between 24- and 36-weeks age of gestation (AOG) for fetal lung maturity from 2017-2019. Clinical characteristics (age, parity, completed ACS dose, AOG at ACS administration and mode of delivery) and glycemic control were retrieved and compared before and after ACS treatment. Data collection began the day or on the day before steroids were given and continued until discharge or delivery.

Included were 42 pregnant women with GDM. Of these, 28 women with GDM were treated by diet alone (Group A) while 14 women with GDM were started on insulin in addition to diet (Group B). After betamethasone therapy was initiated, only three (Group A1; n=3/28) patients had good glycemic control with diet alone and the rest were given insulin treatment (Group A2; n=25/28). In this subpopulation of Group A2, insulin requirement within 24 hours after ACS was at 0.3 units per kg of body weight. There was a steady increase with maximum requirement observed on day 4 and decreased thereafter to 0.33 units per kg of body weight on day 5. For GDM women in Group B, only three maintained their insulin dose (Group B1; n=3/14) while 11 (Group B2; n=11/14) women with GDM previously on insulin, required further increase in insulin from day 1-2 reaching 140% increase in insulin dose on day 2. Thereafter, there was a gradual decrease of insulin dose almost returning to initial dose on day 5.

Insulin initiation was observed among GDM diet-controlled mothers (Group A) who were given ACS therapy at ≥31 weeks age of gestation. Age, parity, family history of diabetes and mode of delivery did not have significant effects on insulin use nor increased insulin requirement. Fasting capillary glucose (FCG) and one-hour post-prandial capillary glucose (PPCG) were elevated within 24 hours after administration of corticosteroid (betamethasone) in 60%-70% of our population. The FCG values remained elevated on day 2-3 in about 70% of patients. While the first hour PPCG was elevated in 85% of patients on day 2 and remained elevated in 70% of women on day 3-4, it reached 53% on day 5. Insulin requirement among Group B2 reached to 140% increase in insulin dose on day 2 followed by a gradual decrease of insulin dose almost returning to initial dose on day 5.

ACS administration caused maternal hyperglycemia in Filipino women with GDM during the first 24 hours and lasting up to five days. Both fasting glucose and post-prandial glucose were elevated, hence intensified monitoring of maternal glucose levels and temporary addition or increase of insulin doses may be necessary. The timing (≥31 weeks AOG) of administration of ACS on GDM women was associated with subsequent insulin initiation but only on patients initially controlled on diet alone.

BACKGROUND/IMPORTANCE OF THE STUDY

At present, there is not much data on the prevalence of cancer in the young adult population in the local setting, in addition to prevalence and determinants of distress in this population. The findings of this study may help to understand the current situation of this young population, and it may also provide a reference for further improving outcomes among these patients who have a distinct set of needs compared to the older counterparts, in addition to a long life expectancy ahead of them.

This study employed an observational cross-sectional design that included young adult cancer patients, aged 19 to 39 years old, seen at the hospital outpatient clinics and Cancer Center from October 2023 to December 2023. Demographic and clinical data were collected. The participants were also asked to fill out the National Comprehensive Cancer Network (NCCN) Distress Thermometer (DT) Screening Tool and Problem List after signing the written informed consent. Data were collated and analyzed per clinical variable.

The mean age of the participants was 34.55 years (SD=3.97), with most of them being 36 to 39 years old (51.67%). Comparative analyses of different demographic and clinical characteristics indicated that none of the characteristics were significantly different between those without and with significant distress levels (p >0.05). The mean distress score was 4.11 (SD=2.60) and categorizing these scores using the established cut-off score showed that 58.33% (95% CI = 44.88% to 70.93%) had distress. Time from cancer diagnosis significantly predicted distress development, specifically between 6 and 12 months from cancer diagnosis (aOR = 0.03, p = 0.042). Factors significantly contributing to distress are concerns on changes in eating, loss or change of physical abilities, worry or anxiety, sadness or depression, loss of interest or enjoyment, loneliness, changes in appearance, feelings of worthlessness or being a burden, relationship with friends, ability to have children, taking care of oneself, finances, access to medicine, issues on sense of meaning or purpose, and on death, dying and afterlife (pCONCLUSION

Significant distress is present in more than 50% of young adult cancer patients seen in a private tertiary institution in the Philippines. The time from cancer diagnosis significantly predicted distress development. Emotional and practical concerns significantly contributed to distress in this population.

OBJECTIVE

This study aimed to determine if selenium supplementation for a period of six months can decrease signs and prevent worsening of mild Graves’ ophthalmopathy among Filipino patients.

We conducted an open-label, assessor-masked, randomized controlled trial involving adult patients diagnosed with mild Graves’ ophthalmopathy. Participants were divided into two groups: one group received standard care (eye drops) alone (control group), while the other group received an additional 200 mcg/day oral selenium supplementation alongside standard care. Inclusion criteria encompassed adult patients with Graves’ hyperthyroidism presenting at least one sign of mild ophthalmopathy and a disease duration of less than 18 months. Statistical analyses were performed using independent sample t-test, Mann-Whitney U test and Fisher’s Exact/Chi-square test to compare means, ranks and frequencies between the two intervention groups. Paired sample t-test, Wilcoxon signed rank test and McNemar test were employed to assess changes from baseline to the third and sixth month observations.

A significant difference in clinical activity score (CAS) was observed between the selenium supplementation group and the control group. Initially, 14 eyes (33.33%) in the selenium group exhibited a CAS score of 0, which increased to 27 eyes (64.29%) at the third month of treatment and slightly decreased to 26 eyes (61.9%) at the sixth month. Conversely, the control group had 11 eyes with a CAS score of 0 at baseline, which increased to 16 eyes (38.1%) at three months and decreased to 14 eyes (33.33%) at the sixth month. The improvement in CAS was significantly associated with reductions in caruncle and plica swelling (p = 0.040). Further analysis revealed a statistically significant difference in CAS between the treatment and control groups (p = 0.017) at the sixth month mark.

Selenium supplementation provided significant benefit in reducing the signs and preventing deterioration of mild Graves’ ophthalmopathy, as indicated by improved CAS scores. Future research exploring baseline and end of treatment selenium concentrations in the Philippines is recommended to further substantiate these findings.

INTRODUCTION

Papillary thyroid cancer (PTC) is generally considered to be an indolent disease with relatively good prognosis. However, some studies have shown that the Filipino population has a higher risk for disease recurrence compared to non-Filipino patients and hence early identification and management during the follow-up period would be beneficial, especially those in whom risk factors for recurrence were identified.

This study aims to identify determinants for disease recurrence of patients with papillary thyroid carcinoma (as defined by the American Thyroid Association (ATA) guidelines 2015) diagnosed from January 1, 2013-December 31, 2017, seen at the University of Santo Tomas Hospital (USTH) outpatient endocrine clinic and underwent total thyroidectomy with or without radioactive iodine ablation therapy.

Retrospective review of outpatient medical records of 82 patients with PTC who underwent total thyroidectomy with or without radioactive iodine (RAI) therapy and achieved excellent response (ER) to therapy was performed. Baseline clinical profile such as age at diagnosis, sex, family history of thyroid cancer, family history of goiter, histopathology result, serial thyroglobulin (Tg), anti-thyroglobulin (anti-Tg) levels, whole body scan reports, neck ultrasound reports and RAI doses were collected. Logistic regression analysis was used to identify determinants to the development of worsening response.

Of the 82 patients, 18 (21.9%) developed worsening response to therapy. Predictors of poor outcomes identified from previous studies such as age, sex, extent of disease, size and multifocality of tumors, ATA risk classification and initial dynamic risk assessment, RAI therapy, level of thyroid-stimulating hormone (TSH) suppression were analyzed. After logistic regression analysis, there was no significant association between variables and progression to worsening response that were previously identified in other studies.

Even though no significant association between investigated variables and worsening response were identified in this study, previous studies with larger populations that had exhibited positive association should be considered and hence current Philippine guidelines for the management of PTC must still be applied.

INTRODUCTION

Patients with diabetes are at higher risk of developing severe COVID-19 infection with a two-fold increased risk of mortality. This study described the risk factors affecting clinical outcomes of confirmed COVID-19 patients with diabetes mellitus at the University of Santo Tomas Hospital, Manila, Philippines.

This retrospective study included 204 patients with COVID-19 (34 with known type 2 diabetes and 2 with new-onset diabetes) from March to October 2020. Clinical characteristics and laboratory parameters were collected and analyzed in subjects with diabetes. A univariate logistic regression was used to calculate the odds ratios and 95% confidence interval (CI) for the patient’s risk factors associated with mortality or poor prognosis.

Moderate COVID-19 infection occurred in 52.8% of type 2 diabetes mellitus (T2DM) patients and critical COVID-19 infection in 27.8%. All patients with critical COVID-19 infection presented with acute respiratory distress syndrome, half had concomitant septic shock and respiratory failure was observed in 27.8%. The average length of hospital stay was approximately 17.5 days. T2DM patients with established atherosclerotic cardiovascular disease (ASCVD) are 5.1 times (95% CI 1.2 to 21.4) more likely to develop severe or critical COVID-19 infection, and more likely to stay in the hospital for more than 14 days. HbA1c >8.5% is a potential risk (OR = 3.7, 0.6 to 21.6) for severe to critical disease. T2DM patients with concomitant coronary artery disease are 7.6 times (95% CI 1.3 to 43.4) more likely to stay longer (more than 14 days) as compared to those without existing coronary artery disease. Prior statin use was a significant risk factor for ICU admission (p-value 0.0341). Other potential risk factors affecting clinical outcomes are obesity (OR 3, 0.4 to 22.7), prior use of thiazolidinedione (OR 7.8, 0.5 to 126.7) or sodium-glucose transporter 2 (SGLT2) inhibitors (OR 7.5, 0.4 to 145) and prior use of anti-thrombotic (OR 4.6, 0.4 to 56.8). The recovery rate of T2DM patients hospitalized for COVID-19 infection was 86.1%.

Patients with T2DM are more vulnerable to COVID-19 infection. The presence of established ASCVD increases the likelihood of severe COVID-19 disease as well as longer length of hospital stay for more than 14 days. Early recognition and prompt treatment led to a favorable recovery rate.

BACKGROUND

Curcumin has been investigated as a potential natural solution to prevent or even treat skeletal muscle decline. There are a number of externally sourced finished products (ie, those imported from other countries) containing curcumin, but high cost limits their usage. The emerging research and development of locally sourced curcumin is an opportunity to produce high-quality oral supplements comparable to existing imported products.

The primary purpose of this study is to determine the effects of oral administration of a local curcumin formulation on skeletal muscle using an animal model that similarly demonstrated the course of human sarcopenia.

Purpose-bred 11- to 12-week-old female Sprague Dawley (SD) rats will be used in this study. SD rats are extensively used in animal models of human diseases and conditions such as diabetes, obesity and sarcopenia. Female rats have been selected because they do not demonstrate more temperature or activity variance and have more stable behavior compared to males. To simulate sarcopenia in this animal model, the tail suspension (TS) method was utilized. The TS method involves decreased hind limb function by suspending the animal’s tail for the duration of treatment. The laboratory animals will be randomized to receive any of the four treatments: (1) low-dose curcumin + vehicle; (2) high-dose curcumin + vehicle; (3) vehicle only; and (4) control (distilled water). The interventions will be subdivided into two: 2-week treatment and 4-week treatment. The gastrocnemius muscles on both sides will be excised and weighed, and the muscle tissues subjected to rapid freezing in acetone-dry ice and sliced into 10 μm-thick sections for staining. Examination of muscle architecture and computation of atrophy factors will be performed. The presence of connective tissue, fat tissue and number of atrophic muscle cells will be determined. Accurate quantitative detection of the rat total AMP (adenosine monophosphate)-Activated Protein Kinase will be performed in the gastrocnemius muscle tissue utilizing the enzyme-linked immunosorbent assay kit.

BACKGROUND

The migration from classroom learning to real patient encounters during clinical clerkship is a transformative journey that carries with it many challenges which serve as rich sources of meaning. The actual patient interactions are pivotal opportunities that provide transcendental meanings which contribute to the well-rounded development of medical clerks, ultimately enhancing their ability to deliver better patient care.

Utilizing a qualitative phenomenological approach, the study allowed exploration of intricate layers of meaning embedded within the encounters of three female medical clerks in a medical university hospital in Manila, Philippines. The gathered narratives were analyzed and meanings were derived from these statements. The identified meanings were then organized into themes and essential insights that represented the core essence of the phenomenon being studied.

The reflections extracted from narratives revealed the emergence of 10 significant major themes stemming from medical clerks’ patient encounters. These encounters were consistently described as a sacred responsibility, providing opportunities for profound connections, resilience, deepened faith and comprehensive personal and professional development within a caring and compassionate environment.

The transformative journey was marked by profound personal and spiritual growth among medical clerks. Beyond developing their clinical skills, they experienced a transcendence that spoke to human desire for meaning beyond the material world. This "spirituality of encounter" fostered deeper connections with patients and enriched their perspectives on clinical practice that can further enhance their holistic development as medical students.
