BACKGROUND AND OBJECTIVE

Colorectal cancer (CRC) has the third highest incidence in the Philippines. Currently, there is a paucity in literature that is focused on the knowledge, attitudes, and perceptions of Filipinos regarding CRC screening. This is the first study in the Philippines that describes this.

This is a cross-sectional study that validated a 52-item Filipino questionnaire on the knowledge on colorectal cancer, willingness to undergo CRC screening, and perceived benefits and barriers to fecal occult blood test (FOBT) and colonoscopy. The study enrolled household heads more than 20 years of age residing in both urban and rural communities in the Philippines.

The UP-PGH CRC KAP (University of the Philippines – Philippine General Hospital Colorectal Cancer Knowledge, Attitudes, and Practices) and Rawl Questionnaire’s validity and internal consistency were established in a pilot study of 30 respondents. A total of 288 respondents were then enrolled to the main study group with a median age of 54.0. Knowledge scores for prognosis and utility of CRC screening were modest (6.3/12 and 8.4/20, respectively). Perceived benefit scores to FOBT and colonoscopy were high (9.9/12 and 13.9/16, respectively).Median scores to barriers to FOBT and colonoscopy were intermediate (22.5/36 and 35.8/60, respectively). Notably, a vast majority (86.1%) were willing to participate in CRC screening programs initiated by the government, and 46.9% agreed to undergo screening tests even as out-of-pocket expense.

The UP-PGH CRC KAP Questionnaire as well as the Filipino translation of the Rawl Questionnaire are reliable and valid tools in extensively assessing the knowledge of Filipinos on CRC and willingness to undergo screening, as well as the benefits of and barriers to FOBT and colonoscopy. Knowledge scores were modest suggesting that directed educational campaigns and awareness programs can aid in increasing awareness about CRC and its screening. Household income and highest educational attainment were significantly positively correlated with knowledge scores, and perceived benefits of and barriers to CRC screening. Scores were generally comparable between urban and rural communities.

OBJECTIVES

Blood glucose levels of the majority of Filipino patients with type 2 diabetes (T2D) remain uncontrolled. Insulin degludec/insulin aspart (IDegAsp) is a fixed‑ratio coformulation of the long‑acting basal insulin degludec and the rapid acting prandial insulin aspart. The realworld ARISE (A Ryzodeg® Initiation and Switch Effectiveness) study investigated clinical outcomes across six countries in people with T2D who initiated IDegAsp. This publication presents the clinical outcomes of the Filipino cohort from a subgroup analysis of the ARISE study.

This 26-week, openlabel, noninterventional study examined outcomes in adults with T2D initiating or switching to IDegAsp (N=185) from other antidiabetic treatments per local clinical guidance.

Compared with the baseline, there was a significant improvement in glycated hemoglobin at the end of the study (EOS) (estimated difference [ED] −1.4 [95% confidence interval −1.7, −1.1]; P < 0.0001). Fasting plasma glucose (ED −46.1 mg/dL [−58.2, −34.0]; P < 0.0001) and body weight (ED −1.0 kg [−2.0, −0.1]; P = 0.028) were significantly reduced at EOS compared with baseline. IDegAsp was associated with a decrease in the incidence of selfreported healthcare resource utilization. Adverse events were reported in eight (4.3%) participants.

Initiating or switching to IDegAsp was associated with improved glycemic control, lower body weight, and lower HRU for people with T2D in the Philippines. No new, unexpected AEs were reported.

The COVID-19 pandemic created the urgent need to use online and virtual platforms to facilitate development of skills and competencies as part of remote learning of students. MyDispense®, a learning management system developed by Monash University in Australia, is a practice-based online tool utilized by the University of the Philippines College of Pharmacy to teach dispensing skills in Dispensing and Incompatibilities courses (Phar 154 and Pharm 133). This commentary describes how MyDispense® was used as an online retail pharmacy simulation through the SEIPS (Systems Engineering Initiative for Patient Safety) model, with discussion on how the person, tasks, organization, tools and technology, and virtual environment work within the teaching and learning process in dispensing. The application of MyDispense® as a learning platform both in remote and traditional teaching can be further explored to maximize its features and utility.

Aims: Bacillus thuringiensis Y1 is a copper-tolerant bacterium that can serve as a model for the elucidation of the mechanism of energy metabolism under simulated copper stress. This study aimed to elucidate the effects of simulated copper stress on the genes associated with the biosynthesis of polyhydroxyalkanoates (PAH) and the metabolism of polyphosphates (PP). Methodology and results : The gene expression study involved the growth of the bacterium in nutrient broth supplemented with two concentrations of copper sulphate (0.4 mM and 0.8 mM), followed by RNA extraction and quantification of four and 11 genes associated with the metabolism of polyphosphate (PP) and polyhydroxyalkanoates (PAHs) respectively, using reverse transcription quantitative polymerase chain reaction (RT-qPCR). Three genes associated with polyphosphate metabolism, which are polyphosphate kinase (ppk), exopolyphosphatase (ppx) and NAD kinase (ppnk), were all shown to be upregulated by both 0.4 mM and 0.8 mM copper, except for the 5’-nucleotidase (surE) gene that was downregulated under the second treatment. Among the 11 genes associated with the metabolism of polyhydroxyalkanoates, only the 3-ketoacyl-CoA-thiolase (phaA) gene was upregulated in both treatments and highly expressed in the second treatment; the majority were downregulated and repressed. Conclusion, significance and impact of study The study demonstrated that copper induces the metabolism of polyphosphates in B. thuringiensis Y1 that serve as an alternative source of energy under copper stress. This model can be extended to the study of other species of Bacillus under environmental stress.

INTRODUCTION: Salba-chia (Salvia hispanica L.) is a popular functional food containing high levels of protein, total dietary fiber, and is an excellent source of α-linolenic acid. Chia seeds significantly decreases weight, suppresses appetite, and has a potential benefit in the management of Type 2 diabetes mellitus (T2DM). This study aimed to determine the effectiveness of chia seeds as an adjuvant treatment for T2DM. METHODS: Randomized controlled trials from 1990 onwards involving Type 2 diabetic patients given chia seed were included. PubMed, Cochrane, ClinicalKey, Google Scholar, and Hinari were searched systematically using MeSH terms “chia”, “Salvia hispanica”, “dietary supplement”, and “diabetes”. The quality of trials was assessed using the Cochrane Collaboration tool. Data on the study design, blinding status, characteristics of participants, medications taken by participants, chia seed intervention, comparator, duration of intake, and interval of assessment were extracted. The percent change of outcome from baseline was compared between the chia and control groups. RESULTS: Four randomized trials with a total of 213 diabetic patients were enrolled in the treatment group using ground salba-chia or the control group using bran. The supplementation of chia resulted in a statistically significant decrease in fasting glucose (-2.90 mmol/L; 95% CI, -3.08, -2.72; p < 0.001), waist circumference (-2.49 cm; 95% CI -2.81, -2.17; p < 0.001), total cholesterol (-2.72 mmol/L; 95% CI -3.68, -1.74; p < 0.001), HDL (-3.69 mmol/L; 95% CI -3.95, -3.42; p < 0.001), LDL (-3.22 mmol/L; 95% CI -4.08, -2.36; p < 0.001); and an increase adiponectin levels (6.50 mg/L; 95% CI 6.25, 6.25; p < 0.001). CONCLUSION Intake of chia seeds resulted in a statistically significant decrease in fasting blood glucose, waist circumference, total cholesterol levels, HDL and LDL cholesterol levels, and increased adiponectin. Chia seeds are generally safer and have lesser side effects compared to the placebo. Chia is effective as adjunctive treatment for Type 2 diabetic patients.

Background: Nasopharyngeal swab/oropharyngeal swab (NPS/OPS) qRT-PCR is the gold standard for detecting SARS-CoV-2. However, it has its own limitations including cost and invasiveness. As an alternative, individual qRT-PCR testing of saliva samples was validated and shown to be comparable in sensitivity and specificity with NP-OP qRT-PCR. To further maximize its utility, the researchers wish to explore antigen and pooled testing methods. Objective: The study aimed to evaluate the diagnostic accuracy of detecting SARS-CoV-2 infection using saliva-based pooled qRT-PCR and rapid antigen test compared with individual saliva qRT-PCR. Methodology: In this retrospective cross-sectional study, saliva specimen from individuals aged 18 years old and above from the outpatient specimen collection station at the Philippine Children’s Medical Center were tested individually using qRT-PCR (Mag-bind RNA Extraction Kit/MACURA, Allsheng Extraction Machine, Sansure PCR kit, and MA-600 Sansure Biotech). Non-probability convenience sampling was utilized. Based on the individual results, pools of five (5) individual specimens, which includes one (1) positive sample were tested with qRT-PCR for sensitivity. DNK-2150-1S Dynamiker SARS-CoV-2 Ag Rapid Test (Dynamiker Biotechnology Co., Ltd., Tianjin, China) was also used to test individual saliva specimens. . Out of 196 individual saliva specimens, 73 were detected to have SARS-COV-2 by qRT-PCR, while the remaining 123 were negative. Compared with the individual saliva qRT-PCR, rapid antigen tests done showed sensitivity of 46.58% (95% CI 35.13%, 58.02%), specificity of 86.18% (95% CI 80.08%, 92.28%), positive and negative predictive value of 66.67% (95% CI 53.71%, 79.60%) and 73.10% (95% CI 65.89%, 80.32%) respectively. Based on the results of individual saliva-based qRT-PCR, 62 pools were tested and showed sensitivity of 98.39% (95% CI 91.34%, 99.96%). Conclusion and Recommendation Pooled saliva-based testing for SARS-CoV-2 is comparable with individual saliva-based rapid antigen testing. The use of rapid antigen testing is less sensitive and less specific compared with qRT-PCR consistent with prior reports. Additional studies are recommended to determine optimal conditions for testing.

Aims: The former Mamut Copper Mine, acid mine drainage site represents an anthropogenic altered landscape characterized by its acidic topsoil which is contaminated primarily with copper. Even though the mining operation was ceased at 1999, the bacterial diversity in this area has never been investigated. This study was conducted to ascertain the bacterial diversity of this abandoned copper mine and correlate it to the copper concentration in the soil. Methodology and results: Soil samples were collected from 7 sites near the mine pit and the vicinity. Soil samples were assessed for soil copper elemental concentration using inductively coupled plasma optical emission spectrometry and bacteria were isolated via serial dilution followed by culture on nutrient agar plates. Phylogenetic analysis was done based on the full-length sequences of 16S rRNA gene. Twenty-four phylotypes were obtained from the 7 locations which originated from the phyla Firmicutes, Actinobacteria, Bacteroidetes and Proteobacteria. The results of the study indicated that site 2 (6.030223°; 116.658030°), located in between the mine pit and the mine factory with a copper concentration of 88.96 ppm, possessed the most diverse bacterial community with a Shannon diversity index (H) of 1.68, evenness (EH) of 0.94 and richness (S) of 6. Conclusion, significance and impact of study Current study revealed that there was a positive correlation between the copper concentration and the H index and the richness, but this was not reflected in the evenness. This is the first report of bacterial diversity from the former Mamut Copper Mine site. The data provided a valuable insight for the future monitoring of the bacterial community in this ecologically important niche.

The pattern of antibiotics prescribed to patients with peripheral lymphadenopathy was assessed and compared with existing standard treatment guidelines (STGs) in Papua New Guinea (PNG). Information was obtained from patients referred to the Port Moresby General Hospital for fine needle aspiration biopsy by interviewing patients and reviewing patients’ clinic attendance record books and referral letters. Of the 107 patients recruited for the study, 51 (48%) were prescribed antibiotics and, of these, prescription data were obtained from 40 (78%). Amoxycillin, which is recommended as a first-line antibiotic for peripheral lymphadenopathy in PNG STGs, was prescribed in only 18/40 patients (45%). There was also high variability in other antibiotic selection, antibiotic combinations and treatment duration. The results highlight a need for ongoing training on rational antibiotic prescribing.
