Virgin coconut oil as adjunctive therapy for hospitalized COVID-19 patients in a Tertiary Referral Hospital: A randomized controlled trial

Background@#Virgin coconut oil (VCO) has anti-viral and anti-inflammatory properties, making it a potential therapeutic candidate against COVID-19 infection.@*Objective@#To determine the efficacy and safety of VCO as adjunctive therapy for hospitalized patients with COVID-19.@*Methods@#We conducted a randomized, open-label controlled trial involving laboratory-confirmed COVID-19 patients admitted at the Philippine General Hospital. The study participants were randomized to the intervention group who received virgin coconut oil with local standard of care, or to the control group who received local standard of care alone.@*Results@#We enrolled 39 participants into the VCO group and 38 participants into the control group. Significantly fewer participants in the VCO group had abnormal CRP levels at the end of treatment compared to control. (relative risk [RR] 0.75, 95% confidence interval [CI] 0.58 to 0.95; p=0.02) No significant difference was found in the duration of hospital stay (mean 9.33 days for VCO vs. 10.29 days for control; p=0.45) and time to symptom resolution (mean 6.8 days for VCO, vs. 6.74 days for control; p=0.91). Although the proportion of patients who developed the secondary outcomes of mortality, need for ICU admission, need for invasive ventilation, and negative viral conversion was lower in the VCO group, results did not reach statistical significance. The VCO group had larger reduction in the inflammatory markers ferritin, lactate dehydrogenase, TNF-alpha, IP-10 and IL-6, but results did not reach statistical significance. Adverse events were significantly higher in the VCO group (RR 4.87, 95% CI 1.14 to 20.79; p=0.03).@*Conclusion@#This clinical trial on hospitalized patients showed significant benefit in CRP levels of participants given VCO compared to control. There was no significant benefit in the use of VCO as adjunctive therapy in reducing duration of hospital stay. Larger studies are needed to conclusively demonstrate the effect of VCO on other clinical outcomes and inflammatory markers.

Clinical outcomes of Gravidocardiac patients in Silliman University Medical Center from January 2015 to December 2019: A retrospective study

Background@#Cardiac disease increases morbidity and mortality in pregnant patients. This is found in both developing countries and underdeveloped countries. Cardiovascular demand increases with pregnancy, causing additional stress on a diseased heart. This then poses a greater risk of complications; thus, specialized care involving an Obstetric-Gynecologist and a Cardiologist is warranted. The Modified WHO Classification of Maternal Cardiovascular Risk, CARPREG, and CARPREG II predict risk among gravidocardiac patients and corresponding needed medical attention perinatally. Little data has been known on the clinical outcomes of pregnancy among gravidocardiac patients in the Philippines. This study aims to gauge the clinical outcomes of gravidocardiac patients admitted to a tertiary hospital in Dumaguete City.@*Methods@#A retrospective, cross-sectional descriptive study was carried out among all gravidocardiac patients admitted for labor and delivery between January 2015 and December 2019. A chart review of the cases satisfying the inclusion criteria was done. Data gathered were tabulated, and a Chi-Square was used to assess if there was a significant relationship between the cardiac condition and the mode of delivery, duration of pregnancy, maternal outcomes, and fetal outcomes.@*Results@#Cardiac lesions noted among gravidocardiac patients include mitral valve prolapse, which comprised the majority of cases, patent ductus arteriosus, ventricular septal defect, mitral valve regurgitation, aortic valve regurgitation, atrial septal defect, and peripartum cardiomyopathy. Pregnancies were mainly carried to term with vaginal delivery as the primary mode of birth. Maternal outcomes were generally favorable, with no deaths recorded. Fetal outcomes were variable among cases, and fetal mortality was recorded at 3.92%. A significant relationship was seen between maternal cardiac condition and maternal outcomes of the pregnancies.@*Conclusion@#Among pregnant patients with cardiac conditions, maternal outcomes of pregnancy can be predicted in association with the cardiac condition. There is a great need to educate the public on the need for proper perinatal care when a cardiac condition in pregnancy is detected.

Introduction. Tuberculosisis called multifocal (TMF) when there is involvement of at least two non-contiguous extrapulmonary sites, whether or notassociated with pulmonary involvement. This study aimed to study the epidemiological, diagnostic and evolutionary aspects of FMT in the pneumo-phthisiology department of the CHU-RN of N'Djamena. Materials and method. This was a 5-year retrospective study with a descriptive aim from January 2018 to December 2022. The variables studied were epidemiological, clinical and progressive. Results. In total, 185 patients were included out of 2001 cases of tuberculosis, i.e. a frequency of 9.24%. The average age was 34.1 years with extremes of 16 and 75 years. The sex ratio was 1.28. Unemployed patients were the majority, i.e. 47% of cases. The notion of tuberculosis contagion represented 13.5% of cases, and 66.5% of patients were vaccinated with BCG with an HIV seroprevalence of 54.6%. All the usual signs of tuberculosis were present. The pulmonary location was the most represented (66.2%) followed by the lymph node location (48.6%). In 80% of cases, bifocal localization. Mortality was 21.6% for an average hospital stay of 20.26 days. Conclusion.Multifocal tuberculosis is a rare and serious form, which generally occurs in patients infected with HIV, but immunocompetent subjects can also be affected. Anti-tuberculosis treatment must be started as quickly as possible to avoid complications.

Maternal satisfaction with childbirth services among postnatal mothers at a primary health center

Background: Primary health centers (PHC) are the first point of contact among the public and structured health services. Maternal satisfaction is an indicator of the quality of services received by the mother during their childbirth experience at the primary health centers. This study aimed to assess the maternal satisfaction of postnatal mothers with childbirth services at a primary health center. Methods: A descriptive study was undertaken at a conveniently selected 24-hour functional primary health center. Maternal satisfaction of mothers delivering at the selected PHC was assessed by using the standardized SMMS tool. 36 mothers selected by convenience sampling were interviewed. Results: All (100%) mothers were satisfied with their childbirth experience (overall mean score 143.3 and SD 5.68). Mothers expressed their highest level of satisfaction with the childbirth experience as one of their best experiences (4.9±.3), they agreed that doctors did all interventions they could do (4.8±0.4) and also, they said that doctors and nurses explained them about all new situations related to labor (4.4±0.5). Mothers were least satisfied with the management of labor pain (1.9±1), nurses could have given them a little more time to start their breast feed (3.1±0.8) and if they could have started breast-feeding a little early (3.2±1.2). Conclusions: Maternal satisfaction is an important indicator of maternal and newborn services provided at any health care facility. Assessing the mother’s perspective is a good determinant of their expectations and can help improve the quality of services at the primary health centers.

Impact Of Communication Skills Training in Postgraduate Medical Education

Background: Effective communication is a key feature of optimal doctor-patient relationship. As the postgraduate curriculum lacks standardized teaching and assessment, this study aimed to assess effec-tiveness of training program on communication skills of postgraduate medical students. Materials and methods: A prospective, interventional study was conducted among first year postgrad-uate medical students from different clinical specialty. Training program included introduction to prin-ciples of communication with basics of doctor-patient relationship, administering informed consent, breaking bad news and counselling patients with HIV/cancer. Pre and post-test skill assessment by Fac-ulty and postgraduate (PG) self-rating was carried out using KEECC-A Assessment tool for seven core communication competencies. Perception of students on training program was collected via feedback questionnaire. Results: Forty-three postgraduate medical students participated. Statistically significant increase in communication skills scores was observed post training with mean post-test assessment scores of 24.26�94, p<0.001(rating by faculty), 25.19�76, p<0.001(PG self-rating) and high degree of internal consistency was found. Students perceived the training program as valuable and highlighted its im-portance as a part of curriculum. Conclusion: Training program significantly enhanced communication skills of postgraduate medical students. Integration of standardized teaching and assessment of communication skills is essential for better healthcare practice and optimal doctor-patient relationship.

Post-radiation neutrophil-to-lymphocyte ratio is a prognostic marker in patients with localized pancreatic adenocarcinoma treated with anti-PD-1 antibody and stereotactic body radiation therapy

Purpose@#To investigate the role of pre- and post-stereotactic body radiation therapy (SBRT) neutrophil-to-lymphocyte ratio (NLR) in patients with localized pancreatic cancer treated with anti-PD-1 (programmed cell death protein-1) antibody and SBRT. @*Materials and Methods@#This was a retrospective review of 68 patients with borderline resectable or locally advanced pancreatic cancer treated with anti-PD-1 antibody and SBRT after multi-agent chemotherapy. Immunotherapy was administered with 5-fraction SBRT in the neoadjuvant, concurrent, or adjuvant/maintenance setting. Clinical outcomes included overall survival (OS), local progression-free survival, distant metastasis-free survival, and progression-free survival. Median pre- and post-SBRT peripheral blood markers were compared with the Mann-Whitney U test. Univariate and multivariable analyses (UVA and MVA) were performed to identify variables associated with clinical outcomes. Linear regression was performed to determine correlations between variables and peripheral blood markers. @*Results@#A total of 68 patients were included in the study. The percent change between median pre- and post-SBRT absolute lymphocyte count (ALC), absolute neutrophil count, and NLR were -36.0% (p < 0.001), -5.6% (p = 0.190), and +35.7% (p = 0.003), respectively. Median OS after SBRT was 22.4 months. On UVA, pre-SBRT CA19-9 (hazard ratio [HR] = 1.001; 95% confidence interval [CI], 1.000–1.001; p = 0.031), post-SBRT ALC (HR = 0.33; 95% CI, 0.11–0.91; p = 0.031), and post-SBRT NLR (HR = 1.13; 95% CI, 1.04–1.22; p = 0.009) were associated with OS. On MVA, induction chemotherapy duration (HR = 0.75; 95% CI, 0.57–0.99; p = 0.048) and post-SBRT NLR (HR = 1.14; 95% CI, 1.04–1.23; p = 0.002) predicted for OS. Patients with post-SBRT NLR ≥3.2 had a median OS of 15.6 months versus 27.6 months in patients with post-SBRT NLR <3.2 (p = 0.009). On MVA linear regression, log10CTV had a negative correlation with post-SBRT ALC (regression coefficient = -0.314; 95% CI, -0.626 to -0.003; p = 0.048). @*Conclusion@#Elevated NLR after SBRT is primarily due to depletion of lymphocytes and associated with worse survival outcomes in localized pancreatic cancer treated with anti-PD-1 antibody. Larger CTVs were associated with decreased post-SBRT ALC.

Effectiveness of chia (Salvia hispanica L.) as an adjuvant therapy for Type 2 diabetes mellitus: A systematic review and meta-analysis / The Health Sciences Journal

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.

Hearing and clinical otologic profile of Filipinos living in Southern Tagalog Region IV-A (CALABARZON), Philippines: The Southern Tagalog ENT Hearing Specialists (STENTS) Survey 2012-2017

@#<p><strong>Objective:</strong> To determine the prevalence of hearing loss and otologic diseases among Filipinos living in the Southern Tagalog Region IV-A: CALABARZON (Cavite, Laguna, Batangas, Rizal and Quezon), Philippines.</p><p><strong>Methods:</strong></p><p><strong>               Design:</strong> Retrospective Review of Community Survey Data</p><p><strong>               Setting:</strong> Communities in Region IV-A provinces, Philippines</p><p><strong>               Participants:</strong> 3267 residents of the five provinces aged 0 months and above</p><p> <strong>Results:</strong> About 71.29% and 74.60% had at least mild hearing loss, in right and left ears, respectively.

Toll-like Receptor 2 in Autoimmune Inflammation

TLR signaling is critical for broad scale immune recognition of pathogens and/or danger molecules. TLRs are particularly important for the activation and the maturation of cells comprising the innate immune response. In recent years it has become apparent that several different TLRs regulate the function of lymphocytes as well, albeit to a lesser degree compared to innate immunity. TLR2 heterodimerizes with either TLR1 or TLR6 to broadly recognize bacterial lipopeptides as well as several danger-associated molecular patterns. In general, TLR2 signaling promotes immune cell activation leading to tissue inflammation, which is advantageous for combating an infection. Conversely, inappropriate or dysfunctional TLR2 signaling leading to an overactive inflammatory response could be detrimental during sterile inflammation and autoimmune disease. This review will highlight and discuss recent research advances linking TLR2 engagement to autoimmune inflammation.

IL-17 and IL-17C Signaling Protects the Intestinal Epithelium against Diisopropyl Fluorophosphate Exposure in an Acute Model of Gulf War Veterans' Illnesses

Gulf War Veterans' Illnesses (GWI) encompasses a broad range of unexplained symptomology specific to Veterans of the Persian Gulf War. Gastrointestinal (GI) distress is prominent in veterans with GWI and often presents as irritable bowel syndrome (IBS).Neurotoxins, including organophosphorus pesticides and sarin gas, are believed to have contributed to the development of GWI, at least in a subset of Veterans. However, the effects of such agents have not been extensively studied for their potential impact to GI disorders and immunological stability. Here we utilized an established murine model of GWI to investigate deleterious effects of diisopropyl fluorophosphate (DFP) exposure on the mucosal epithelium in vivo and in vitro. In vivo, acute DFP exposure negatively impacts the mucosal epithelium by reducing tight junction proteins and antimicrobial peptides as well as altering intestinal microbiome composition. Furthermore, DFP treatment reduced the expression of IL-17 in the colonic epithelium. Conversely, both IL-17 and IL-17C treatment could combat the negative effects of DFP and other cholinesterase inhibitors in murine intestinal organoid cells. Our findings demonstrate that acute exposure to DFP can result in rapid deterioration of mechanisms protecting the GI tract from disease. These results are relevant to suspected GWI exposures and could help explain the propensity for GI disorders in GWI Veterans.

Impact of somatic mutations on clinical and pathologic outcomes in borderline resectable and locally advanced pancreatic cancer treated with neoadjuvant chemotherapy and stereotactic body radiotherapy followed by surgical resection

Purpose@#The purpose of this study was to determine if somatic mutations are associated with clinical and pathologic outcomes in patients with borderline resectable pancreatic cancer (BRPC) or locally advanced pancreatic cancer (LAPC) who were treated with neoadjuvant chemotherapy and stereotactic body radiotherapy (SBRT). @*Materials and Methods@#Patients treated with neoadjuvant chemotherapy and SBRT followed by surgical resection from August 2016 to January 2019 and who underwent next generation sequencing of their primary tumor were included in the study. Next-generation sequencing was performed either in-house with a Solid Tumor Panel or with FoundationOne CDx. Univariate (UVA) and multivariable analyses (MVA) were performed to determine associations between somatic mutations and pathologic and clinical outcomes. @*Results@#Thirty-five patients were included in the study. Chemotherapy consisted of modified FOLFIRINOX, gemcitabine and nab-paclitaxel, or gemcitabine and capecitabine. Patients were treated with SBRT in 33 Gy in 5 fractions. On UVA and MVA, tumors with KRAS G12V mutation demonstrated better pathologic tumor regression grade (TRG) to neoadjuvant therapy when compared to tumors with other KRAS mutations (odds ratio = 0.087; 95% confidence interval [CI], 0.009–0.860; p = 0.036). On UVA and MVA, mutations in NOTCH1/2 were associated with worse overall survival (hazard ratio [HR] = 4.15; 95% CI, 1.57–10.95; p = 0.004) and progression-free survival (HR = 3.61; 95% CI, 1.41–9.28; p = 0.008). On UVA, only mutations in NOTCH1/2 were associated with inferior distant metastasis-free survival (HR = 3.38; 95% CI, 1.25–9.16; p = 0.017). @*Conclusion@# In BRPC and LAPC, the KRAS G12V mutation was associated with better TRG following chemotherapy and SBRT. Additionally, NOTCH1/2 mutations were associated with worse overall survival, distant metastasis-free survival, and progression-free survival.

Role of ultrasonographic optic nerve sheath diameter in the diagnosis and follow-up of papilledema and its correlation with Frisén's severity grading

Purpose: The aim of this study was to compare the ultrasonographic optic nerve sheath diameter (ONSD) in different grades of papilledema and in controls and to evaluate ONSD in atrophic papilledema/optic atrophy when raised ICP was suspected. Methods: Prospective cross-sectional case–control study. Following an ocular examination, papilledema was graded clinically using modified Frisén's grading. An ultrasonographic cross section of the retrobulbar optic nerve was obtained with a posterior transverse scan. Independent t-test and analysis of variance were the statistical tools used in the study. Results: The study included 55 cases and 55 age- and gender-matched controls; mean (± standard deviation) age was 37.17 (±11.25) years and male: female ratio was 49:61. There was a statistically significant difference in the mean ultrasonographic ONSD between cases [4.89 (±0.65) mm] and controls [3.12 (±0.22) mm] (P < 0.001). There was a significant difference in the mean ONSD across Frisén's grades of papilledema (P < 0.001). The mean ONSD in atrophic papilledema was 6.2 (±0.75) mm. Conclusion: In the presence of symptoms, ultrasonographic ONSD >4 mm is diagnostic of papilledema. Ultrasonographic ONSD correlates well with the severity of papilledema and can be used to follow-up patients with chronically elevated ICP. It is useful in detecting raised ICP in the presence of optic atrophy and to distinguish true papilledema from pseudopapilledema.

Association of Erectile Dysfunction and extent of Coronary Vessel involvement by Syntax Score in Coronary Artery Disease patients undergoing Coronary Angiography at Perpetual Succour Hospital from October 2014 – September 2015

Introduction@#Erectile dysfunction (ED) has numerous links to cardiovascular disease. Numerous studies show the severity of ED is strongly associated with atherosclerosis and endothelial dysfunction implicated in the pathogenesis of coronary artery disease (CAD). These common vascular pathways have led to evidence that ED onset may be used as a marker of the severity of CAD as well as a preclinical marker of early onset-CAD. The researchers aim to determine the association of ED and CAD in terms of prevalence, clinical presentation and severity and extent of vessel involvement by SYNTAX score among CAD patients undergoing coronary angiography.@*Methods@#This is a prospective, cross sectional, analytical study design set at Perpetual Succour Hospital – Cebu Heart Institute, a private, tertiary hospital with cardiac specialty units located in Cebu City. This study includes all Filipino patients admitted at Perpetual Succour Hospital suspected to have coronary artery disease based on symptoms of angina, dyspnea or other anginal equivalent with indications to undergo coronary angiography during the period of October 1, 2014 to September 30, 2015 were included.@*Results@#A total of 160 patients were included in the study. The mean age is 57.23 years with most of the patients admitted for stable ischemic heart disease (SIHD) of 54.7%, non-ST elevation acute coronary syndromes (NSTEACS) 33.5% and ST-elevation myocardial infarction (STEMI) 11.8% with multiple cardiovascular risk factors like hypertension, diabetes mellitus, smoking and dyslipidemia. Eighty-two percent complained of ED symptoms with a mean International Index of Erectile Function (IIEF) score of 15.15. Most ED patients identified had mild to moderate ED (31.7%), mild ED (21.7%), moderate ED (17.4%) and severe ED (11.8%). There were only 17.4% of patients who had undergone coronary angiography for CAD complaints that had no ED symptoms on admission. Per clinical presentation, there was a significant association between patients presenting with severe ED, moderate ED and mild to moderate ED with those presenting with SIHD and ACS-NSTEMI on admission, moderate ED and mild to moderate ED. ED was significantly associated with obstructive CAD (p=0.001) and correlated directly with the number of vessels involved (p<0.01) and inversely related to SYNTAX scores (p<0.001). ED symptoms were noted to precede CAD diagnosis by 4.9 to 5.9 years.@*Conclusion@#In conclusion, there is a high prevalence of ED among CAD patients and its existence is significantly associated with obstructive CAD varying directly with extent and number of vessel involvement. There is a significant inverse relationship with severity of ED and SYNTAX scores. The existence of ED was present in all subsets of CAD patients, regardless of presentation of admission and preceded CAD symptoms and diagnosis by four to five years.

Antisickling and Radical Scavenging Activities of Selected Medicinal Plants and Compounds from Mitracarpus villosus (Sw.) DC. Cham

Aims: This study investigated the antisickling and radical scavenging activities of different morphological parts of nine plants, belonging to six families. A bioassay-guided fractionation was carried out on Mitracarpus villosus (Sw.) DC. Cham, which was one of the most active plants. Place and Duration of Study: Drug Research and Production Unit, Faculty of Pharmacy, Obafemi Awolowo University (OAU), Ile Ife, Nigeria between May 2013 and June 2016. Methodology: Plant materials were collected from OAU campus and Ile-Ife town, identified and voucher specimen deposited at IFE herbarium, OAU for future reference. In-vitro radical scavenging and antisickling (by haemoglobin polymerization inhibitory test) activities of extracts and isolated compounds were performed using ascorbic acid and vanillic acid as positive controls respectively. Bioassay-guided fractionation was achieved by combination of various chromatographic procedures and bioassay techniques to isolate the active constituents. Structural elucidation of the isolated compounds was by spectroscopic techniques including NMR and MS. Results: Six of the nine plant extracts showed considerable antisickling and antioxidant activities. Extracts of Emilia praetermissa and M. villosus, were however the most active. Extracts or compound which demonstrated strong radical scavenging activity were also found to demonstrate significant antisickling effects. Bioassay-guided fractionation of M. villosus resulted in the isolation of psychorubrin, quercetin and a mixture consisting of stigmasterol and an unidentified terpene. Quercetin was the most active antisickling and radical scavenging compound with percentage inhibition of 96.46±0.3 and 87.99±0.18 respectively. Conclusion: Mitracarpus villosus ranked second best in activity among the tested plants. Antisickling activity of its isolated compounds was found to increase with increase in the antioxidant capability of the compounds. Quercetin was the most active compound while the non-antioxidant terpenoidal mixture had very weak polymerisation inhibitory effect.

A quasi-experimental study on the effect of a nursery rhyme on the comfort of infants after vaccination in selected barangay health centers in Quezon City / The Health Sciences Journal

INTRODUCTION@#Administration of parenteral medications may cause pain in infants. This study aimed to assess the efficacy of a nursery rhyme in increasing the comfort of infants after vaccination.@*METHODS@#Infants who were brought to six barangay health centers for vaccination were recruited. Infants from three barangay health centers were randomly assigned to the experimental group, while infants from the other three were assigned to the control group. A Filipino nursery rhyme Tatlong Bibe was played to the experimental group. The comfort of each infant was then assessed by a pediatrician prior to, immediately after, and two minutes post-vaccination using the COMFORTB scale. Results were analyzed using independent t-tests.@*RESULTS@#Prior to vaccination, the control and experimental groups had mean COMFORT-B scores of 12.46 and 12.74 (p = 0.634), respectively. The immediate post-vaccination mean COMFORT-B scores were 22.14 and 21.63 (p = 0.420), while the 2 minutes post-vaccination mean COMFORT-B scores were 16.40 and 16.49 (p = 0.927), respectively. There were no significant differences between groups for the three determinations.@*CONCLUSION@#Based on the study results, the nursery rhyme had no significant effect on the comfort of infants after vaccination.

Nyssorhynchus dunhami: bionomics and natural infection by Plasmodium falciparum and P. vivax in the Peruvian Amazon

BACKGROUND Nyssorhynchus dunhami, a member of the Nuneztovari Complex, has been collected in Brazil, Colombia, and Peru and described as zoophilic. Although to date Ny. dunhami has not been documented to be naturally infected by Plasmodium, it is frequently misidentified as other Oswaldoi subgroup species that are local or regional malaria vectors. OBJECTIVES The current study seeks to verify the morphological identification of Nuneztovari Complex species collected in the peri-Iquitos region of Amazonian Peru, to determine their Plasmodium infection status, and to describe ecological characteristics of their larval habitats. METHODS We collected Ny. nuneztovari s.l. adults in 2011-2012, and Ny. nuneztovari s.l. larvae and adults in 2016-2017. When possible, samples were identified molecularly using cytochrome c oxidase subunit I (COI) barcode sequencing. Adult Ny. nuneztovari s.l. from 2011-2012 were tested for Plasmodium using real-time PCR. Environmental characteristics associated with Ny. nuneztovari s.l. larvae-positive water bodies were evaluated. FINDINGS We collected 590 Ny. nuneztovari s.l. adults and 116 larvae from eight villages in peri-Iquitos. Of these, 191 adults and 111 larvae were identified by COI sequencing; all were Ny. dunhami. Three Ny. dunhami were infected with P. falciparum, and one with P. vivax, all collected from one village on one night. Ny. dunhami larvae were collected from natural and artificial water bodies, and their presence was positively associated with other Anophelinae larvae and amphibians, and negatively associated with people living within 250m. MAIN CONCLUSIONS Of Nuneztovari Complex species, we identified only Ny. dunhami across multiple years in eight peri-Iquitos localities. This study is, to our knowledge, the first report of natural infection of molecularly identified Ny. dunhami with Plasmodium. We advocate the use of molecular identification methods in this region to monitor Ny. dunhami and other putative secondary malaria vectors to more precisely evaluate their importance in malaria transmission.

Low-density lipoprotein cholesterol target attainment in patients with stable or acute coronary heart disease in the Philippines: Results from the Dyslipidemia international study II

Objective@#To quantify the extent of hyperlipidemia and its treatment in patients with stable coronary heart disease (CHD) or an acute coronary syndrome (ACS) in the Philippines.@*Methods@#The Dyslipidemia International Study (DYSIS) II was an observational, multinational study conducted in patients aged ≥18 years with stable CHD or being hospitalized with an ACS. A full lipid profile was evaluated at baseline, and for the ACS cohort, at 4 months after discharge from hospital. Achievement of low-density lipoprotein cholesterol (LDL-C) targets and the use of lipid-lowering therapy (LLT) were assessed.@*Results@#A total of 232 patients were enrolled from 10 centers in the Philippines, 184 with stable CHD and 48 being hospitalized with an ACS. The mean LDL-C level for the CHD patients was 88.0±40.1 mg/dL, with 33.3% achieving the target of <70 mg/dL recommended for very high-risk patients. For the ACS cohort, the mean LDL-C level was 109.0±48.5 mg/dL, with target attainment of 25.0%. The majority of the CHD cohort was being treated with LLT (97.3%), while 55.3% of the ACS patients were receiving LLT prior to hospitalization, rising to 100.0% at follow-up. There was little use of non-statins.@*Conclusions@#For these very high-risk patients from the Philippines, LDL-C target attainment was poor. Opportunities for better monitoring and treatment of these subjects are being missed.

The prevalence of CYP2D6 Gene Polymorphisms among Filipinos and their use as biomarkers for lung cancer risk

Objectives@#The highly polymorphic nature of the CYP2D6 gene and its central role in the metabolism of commonly used drugs make it an ideal candidate for pharmacogenetic screening. This study aims to determine the prevalence of CYP2D6 polymorphisms among Filipinos and their association to lung cancer. @*Method@#Forty seven single nucleotide polymorphisms (SNPs) of the CYP2D6 gene were genotyped from DNA samples of 115 cases with lung cancer and age- and sex-matched 115 controls. @*Results@#Results show that 18 out of 47 polymorphisms have significant genotypic variability (>1% for at least 2 genotypes). No variant is associated with lung cancer. However, rs1135840, rs16947 and rs28360521, were found to be highly variable among Filipinos. @*Conclusion@#This study demonstrated that CYP2D6 polymorphisms are present among Filipinos, which, although not found to be associated with lung cancer, can be useful biomarkers for future pharmacogenetic studies. The SNP rs16947 is found to be associated with cancer and timolol-induced bradycardia; the SNP rs1135840, on the other hand, is only shown to be linked with cancer. The genetic variant rs28360521 is known to be associated with low-dose aspirin-induced lower gastrointestinal bleeding.

Genetic polymorphisms in NAT1, NAT2, GSTM1, GSTP1 and GSTT1 and susceptibility to colorectal cancer among Filipinos

@#Objectives. Polymorphisms in metabolic genes which alter rates of bioactivation and detoxification have been shown to modulate susceptibility to colorectal cancer. This study sought to evaluate the colorectal cancer risk from environmental factors and to do polymorphism studies on genes that code for Phase I and II xenobiotic metabolic enzymes among Filipino colorectal cancer patients and matched controls. Methods. A total of 224 colorectal cancer cases and 276 controls from the Filipino population were genotyped for selected polymorphisms in GSTM1, GSTP1, GSTT1, NAT1 and NAT2. Medical and diet histories, occupational exposure and demographic data were also collected for all subject participants.Results. Univariate logistic regression of non-genetic factors identified exposure to UV (sunlight) (OR 1.99, 95% CI: 1.16-3.39) and wood dust (OR 2.66, 95% CI: 1.21-5.83) and moldy food exposure (OR 1.61, 95% CI:1.11-2.35) as risk factors; while the NAT2*6B allele (recessive model OR 1.51, 95% CI :1.06-2.16; dominant model OR 1.87, 95% CI: 1.05-3.33) and homozygous genotype (OR 2.19, 95% CI: 1.19-4.03) were found to be significant among the genetic factors. After multivariate logistic regression of both environmental and genetic factors, only UV radiation exposure (OR 2.08, 95% CI: 1.21-3.58) and wood dust exposure (OR 2.08, 95% CI: 0.95-5.30) remained to be significantly associated with increasing colorectal cancer risk in the study population.Conclusion. This study demonstrated that UV sunlight and wood dust exposure play a greater role in influencing colorectal cancer susceptibility than genotype status from genetic polymorphisms of the GST and the NAT` genes.
