BACKGROUND

Type 2 diabetes is the most common type of diabetes in the Philippines. Diabetic foot complications represent a prevalent and significant chronic concern for individuals with type 2 diabetes. This poses an immediate community health concern, as diabetic complications may threaten an individual's well-being.

This study intends to cross-culturally adapt the Diabetic Foot Knowledge Subscale (DFKS) and Foot Self-Care Behavior Scale (FSCBS) questionnaires into the Filipino language as an assessment tool among Filipinos with diabetes.

The study employed a psychometric research design, where it entailed Phase A and Phase B. Phase A involved the forward translation of the DFKS and FSCBS questionnaires, followed by the synthesis of the translations and backward translation. Subsequently, an expert committee reviewed the translations and concluded the final version. The final translated versions of the questionnaires ensured that it can be understood by an individual who has a Grade 6 level of reading proficiency. Phase B entailed the validity testing with the evaluation of the expert committee, and reliability testing of the said questionnaires with a sample size of 30 participants. A wash-out period of 24 hours was given for the test-retest reliability, followed by data analysis. The validity and reliability of the questionnaires were measured using the item and scale content validity indices and the internal consistency and test-retest reliability, respectively, to ensure their accuracy and appropriateness. The content validity of the questionnaires was evaluated individually by the experts using a Likert scale from 1-4, with 4 being the highest meaning the item was very relevant and succinct. Scores per item were between 3 and 4, which indicate that the translated version of the items were relevant and succinct or were relevant but needed minor revisions.

The validity scores for the translated DFKS and FSCBS questionnaires were obtained using the Scale Content Validity Index (S-CVI) with a score of 0.96 and 0.92, respectively. Moreover, all items in the questionnaires obtained an Item Content Validity Index (I-CVI) of 0.88-1.00. The DFKS also has an acceptable internal consistency with a Cronbach’s alpha of 0.72, while the FSCBS has a good internal consistency with a Cronbach’s alpha of 0.85. The test-retest reliability shows an acceptable Spearman’s correlation at 0.76 for the DFKS and a strong positive Pearson correlation coefficient at 0.73 for the FSCBS.

The validity of the two questionnaires was acceptable and the test-retest reliability showed a strong positive correlation among the items thereby making the cross-cultural adaptation of the questionnaires successful. The Filipino versions of the DFKS and FSCBS questionnaires accurately measure the knowledge and behavior of individuals with type 2 diabetes, respectively.

BACKGROUND AND OBJECTIVE

Type II Diabetes Mellitus remains a pressing public health concern among Filipino adults, particularly prevalent in urban households belonging to the middle to richest wealth population. As body composition influences glucose metabolism, understanding the potential of anthropometric parameters is vital in predicting fasting blood sugar. This study aims to generate and find the most appropriate model that can detect likelihood of elevated FBS using different anthropometric parameters.

The data set from 2018-2019, 2021 Expanded National Nutrition Survey of Department of Science and Technology - Food and Nutrition Research Institute, consisting of 14,655 adults aged 18–65 years from 33 highly urbanized cities (HUCs) was used in this study. While controlling for study variables, multiple logistic regression was used to determine significant predictors affecting the fasting blood sugar (FBS) status of these adults.

The above normal status of each anthropometric parameter, in the models for BMI (aOR=2.33; pCONCLUSION

There is no single anthropometric parameter that can truly discern the status of elevated FBS. However, it appears the use of waist circumference and waist-hip ratio have the potential to be an indicator especially in settings where the evaluation of the actual FBS of the individuals is not feasible. Future research suggests exploring possible interaction of BP, and FBS, diet quality and adequacy, and the effectiveness of having multiple anthropometric parameters in one model.

BACKGROUND

Melioidosis is an infectious disease caused by Burkholderia pseudomallei. It is endemic in the Philippines and is underreported. Of the reported cases, the most common comorbidity is diabetes mellitus. The increasing cases of antibiotic resistance and the relatively high mortality rate highlights the need for increased awareness among clinicians regarding this disease. We aim to report a case of Burkholderia pseudomallei resistant to trimethoprim/sulfamethoxazole (TMP-SMX), used in its eradication following initial intravenous therapy.

A 51-year-old male Filipino with poor health-seeking behavior came with generalized body weakness, weight loss, dysarthria, fever, cough, difficulty breathing, bloatedness, dysuria, joint pains, and bilateral lower extremity hyperpigmented macules for four months. He has diabetes mellitus and hypertension and is a mechanic by trade. Initial workups revealed hemoglobin A1c (HbA1c) of 14.7%, and urinalysis with bacteriuria. Imaging revealed bilateral pneumonia on chest xray, hepatosplenomegaly on whole abdomen ultrasound, and old cerebral infarcts on cranial computed tomography scan (CT scan). Empiric antibiotics for the impression of sepsis from community-acquired pneumonia and urinary tract infection were ertapenem and azithromycin. Upon isolation of Burkholderia pseudomallei from blood cultures, the team shifted to TMP-SMX and ceftazidime for initial therapy of melioidosis. Sensitivity showed resistance to TMP-SMX; hence the team revised the antimicrobials to four weeks of levofloxacin and ceftazidime. After eleven hospital days, the team sent the patient home, clinically improved. The team continued levofloxacin for eradication therapy for three months and the patient responded well.

Fever with multi-system involvement in a Filipino patient with diabetes mellitus with significant environmental risk factors, poor glycemic control, splenomegaly, and treatment failure with appropriate empiric antibiotic therapy should raise suspicion for melioidosis. It is paramount that antimicrobial resistance be detected and documented upon isolation of Burkholderia pseudomallei, given the high relapse rates and the need for a prolonged duration of treatment.

OBJECTIVE

To assess the diagnostic accuracy of point-of-care screening using Medios™ Artificial Intelligence (AI) in the diagnosis of diabetic retinopathy (DR).

This is a multi-center, cross-sectional, instrument validation study among adult Filipinos with Type 2 diabetes seen at Endocrine specialty clinics from May to November 2021. Retinal images were captured by a minimally trained nurse using the Remedio Fundus on Phone (FOP). Images were interpreted separately by the Medios™ AI and three retina specialists. The primary outcome measure is the accuracy of Medios™™ AI in diagnosing DR compared to retina specialists’ findings using sensitivity and specificity, predictive values, and likelihood ratios.

A total of 182 subjects with Type 2 diabetes were included in the study. The sensitivity and specificity of the Medios™ AI in diagnosing any DR were 73.68% (95%CI, 57.99-85.03) and 83.74% (95%CI, 79.35-87.35), respectively, compared with the retinal specialists’ findings using the same images. The positive and negative predictive values were 34.57% (95%CI, 25.12-45.41) and 96.47% (95%CI, 93.62-98.07). The positive and negative likelihood ratios were 4.53 (95%CI, 4.26 4.82) and 0.31 (95%CI, 0.26-0.38). The overall diagnostic accuracy of Medios™ AI in detecting DR was 82.69% (95%CI, 78.47-86.23).

The Medios™ AI system showed acceptable diagnostic accuracy when used as a point-of-care screening tool in detecting DR among patients with Type 2 diabetes seen at Endocrine specialty clinics. This technology can be a useful screening tool for endocrinologists as it is relatively inexpensive, safe, and easily performed. It can also shorten the lead time from screening to referral and intervention.

BACKGROUND

Diabetes Mellitus (DM) is a long-term metabolic disease distinguished by persistently elevated levels of glucose in the bloodstream. It affects 7.5% of adults in the Philippines, translating to 4,303,899 adults with diabetes in 2021. Type 2 DM (T2DM), which results from a combination of genetic predispositions and lifestyle choices, is the most prevalent form of diabetes in the Philippines. Foot ulcers are a common and highly comorbid complication of diabetes. By improving the knowledge and behavior regarding foot care using health education strategies, preventing diabetic foot ulcers is achievable.

This study aims to evaluate the effectiveness of health education strategies in improving the knowledge and behavior of participants diagnosed with T2DM regarding foot ulcer prevention in Binangonan, Rizal.

This study uses a quantitative quasi-experimental design. A 2-day workshop will be held by the researchers, including a screening, pretest, orientation on the health education material (HEM), and demonstration of the HEM content, followed by 2-weeks of self-intervention and posttest. The study will include males and females from Binangonan, Rizal, aged 20-79, who are medically diagnosed with T2DM by a physician. The effectiveness of the strategies will be evaluated using paired t-tests based on the mean of the pre-test and post-test scores obtained from the Diabetic Foot Knowledge Subscale (DFKS) and Foot Self-Care Behavior Scale (FSCBS) questionnaire.

The researchers expect an increase in the post-test scores of the participants in the DFKS and FSCBS questionnaires. This would mean increased behavior and knowledge of foot care practices to prevent diabetic foot ulcers after 2 weeks of self-intervention guided by the HEM and strategies.

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.

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

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.

BACKGROUND

There is an increasing population of elderly patients with diabetes. Malnutrition has been associated to higher morbidity and mortality among these patients. Currently, there are limited data on malnutrition and its risk factors among elderly patients with diabetes in the Philippines.

This study determined the prevalence, clinical profile and risk factors associated with malnutrition and identify the association of malnutrition with glycemic status and insulin resistance among elderly patients with diabetes.

This is a cross-sectional study involving 117 elderly patients with diabetes seen at a tertiary hospital in Manila, Philippines. Demographic, anthropometric, and clinical data were collected. Mini-Nutritional Assessment-Short form (MNA-SF), Simple FRAIL questionnaire and Mini-cog assessment were administered. Patients were categorized into normal, at risk for malnutrition, and malnourished using the MNA-SF. Comparative and logistic regression analyses were performed to identify the clinical profile and possible risk factors.

The prevalence of malnutrition was 1.71% with 29.06% at risk for malnutrition. There was no significant difference in demographic, anthropometric and biochemical parameters between the different nutrition statuses. High BMI, central obesity, and increased insulin resistance were observed across all nutrition status. Frail patients had almost five times increased likelihood (OR=4.94, p=0.043) of developing malnutrition. Good glycemic control had two-fold decreased likelihood (OR=0.44, p=0.050) of malnutrition. Insulin resistance was not associated with malnutrition.

Malnutrition is prevalent among elderly patients with diabetes. Frailty and poor glycemic control increased the risk of malnutrition. Therefore, malnutrition screening should be routinely performed among these patients. Diabetes management among elderly patients should include maintaining good glycemic control and preventing frailty and its complications.

BACKGROUND

Gestational diabetes mellitus (GDM) may increase fetal abdominal fat mass, but its correlation with fetal abdominal circumference (AC) is inconsistent. This study compares third trimester fetal AC between adult pregnant patients with and without GDM, and between those managed with diet modification alone versus insulin therapy.

This retrospective cohort study involved 354 Filipino adult pregnant patients at The Medical City admitted for delivery from January 2016 to May 2022. This included 180 patients with GDM, and 174 patients without GDM. One hundred sixteen (116) of the GDM patients were diet-managed, and 64 were insulin-requiring. Participants underwent third trimester fetal AC ultrasound and 75-gram oral glucose tolerance test (OGTT) between 24 to 28 weeks of gestation. The third trimester fetal AC, fetal outcomes and maternal outcomes between patient groups were analyzed using Stata 15.0.

The GDM group had higher rates of cesarean section delivery (70% vs 46.55%, pCONCLUSION

Third trimester fetal AC is significantly larger in women with GDM compared to non-GDM women, regardless of management method. Monitoring fetal AC during the third trimester is important for prenatal care in GDM pregnancies.
