AIM:To describe our clinical experience in treating circumscribed choroidal haemangioma(CCH)in a tertiary referral centre over a fifteen year period prior to photodynamic therapy.METHODS:The departmental database and photographic records of a tertiary referral center were used to identify patients who were treated for CCH between 1992 and 2007.Their case records were reviewed.RESULTS:Visual acuity improved(＞2 Snellen lines)in eleven patients(69%)remained stable in one patient (6%)and deteriorated in four patients(25%).Six of the seven treated with brachytherapy and three of the four treated with transpupillary thermotherapy achieved better visual acuity after treatment.86% of patients treated within six months of onset of symptoms and 50% of patients treated after six months of onset of symptoms noted an improvement in visual acuity.Only one patient in our series had a final VA of 6/60 or worse.Mean follow-up was thirty-five months.CONCLUSION:Visual outcome is better when treatment is performed within 6 months of symptoms.The majority of patients achieved an improvement in visual acuity without any adverse effect following treatment.

BACKGROUND: Diabetes mellitus (DM) is a major cause of morbidity and mortality in the Philippines. Improvement in hemoglobin A1c (HbA1c) remains below recommended targets for Filipino patients. Safe and effective therapies are needed for this population.
OBJECTIVE: To investigate treatment-emergent adverse events (TEAEs) and change in HbA1c among Filipino patients with DM treated with insulin lispro mix 25/75 in a real-world setting.
MATERIALS AND METHODS: This was a prospective, non-interventional, post-marketing surveillance study among 459 Filipinos aged 18 years or older with type 1 or 2 DM. Patients were treated with insulin lispro mix 25/75 according to the approved label, as prescribed by the investigators, and observed for 12 weeks. Occurrence of all TEAEs and change in HbA1c from baseline to final visit were reported.
RESULTS: Mean (SD) treatment duration was 12.93 (5.7) weeks, and mean total daily dose was 0.62 (0.29) units/kg. Eighteen patients (3.9%) experienced 23 TEAEs, the majority of which were mild. None were reported to be related to treatment. No serious TEAEs or hypoglycemic episodes were reported. Mean (95% confidence interval) HbA1c was significantly reduced by -2.03% (-2.19%, -1.87%), and 36.3% of patients achieved HbA1c <7.0% at 12 weeks.
CONCLUSION: In this observational study, no treatmentrelated safety signals using insulin lispro mix 25/75 were detected among Filipino diabetic patients. HbA1c was significantly reduced in Filipino patients with DM at 12 weeks.

BACKGROUND: Prevalence surveys are important to aid in assessing the current burden of diseases, which will impact on the public health agenda as well as preventive interventions and health policies. Three previous local surveys on asthma prevalence of Filipino adults have been carried out. This is the fourth local survey and is also a part of the second NNHeS study, which is carried out every five years. The purpose of the survey is to determine the trend in asthma prevalence and to aid in formulating and evaluating local initiatives.
OBJECTIVE: To determine the prevalence of asthma among Filipino adults
METHODOLOGY: Using a multi-staged cluster sampling methodology, this study evaluated 7,202 adults at least 20 years old, from 3,744 households, 79 provinces and 17 regions. A pre-validated written questionnaire for wheezing among children based on the International Study of Asthma and Allergies of Childhood (ISAAC) was used as the survey instrument. This instrument was adopted since it has been widely used as a case definition for asthma, which allows for comparison of prevalence outcomes across time and population.
RESULTS: The overall prevalence of asthma based on wheezing for the past 12 months was 8.7% (SE 0.4%). Males had a higher prevalence of wheezing for the past 12 months at 9.4% (SE 0.5%) compared to females at 8.2% (SE 0.5%). The overall prevalence of asthma based on wheezing at any time was 14.3% (SE 0.5%). Males had a higher prevalence of wheezing at any time of 14.8% (SE 0.7%) compared to females at 13.8% (SE 0.6%). The prevalence of adult asthma in the rural area was slightly higher than in the urban area (15.3% vs 13.3%), but the difference was not statistically significant.
CONCLUSION: The overall prevalence of adult asthma in the Philippine based on the second NHHeS is 8.7%. This figure is lower than previous reported local prevalence data. The prevalence of adult asthma in the rural and urban setting is almost similar.

Tracking the most recent advances in Coronavirus disease 2019 (COVID-19)‒related research is essential, given the disease's novelty and its impact on society. However, with the publication pace speeding up, researchers and clinicians require automatic approaches to keep up with the incoming information regarding this disease. A solution to this problem requires the development of text mining pipelines; the efficiency of which strongly depends on the availability of curated corpora. However, there is a lack of COVID-19‒related corpora, even more, if considering other languages besides English. This project's main contribution was the annotation of a multilingual parallel corpus and the generation of a recommendation dataset (EN-PT and EN-ES) regarding relevant entities, their relations, and recommendation, providing this resource to the community to improve the text mining research on COVID-19‒related literature. This work was developed during the 7th Biomedical Linked Annotation Hackathon (BLAH7).

Accessible negative results are relevant for researchers and clinicians not only to limit their search space but also to prevent the costly re-exploration of research hypotheses. However, most biomedical relation extraction datasets do not seek to distinguish between a false and a negative relation among two biomedical entities. Furthermore, datasets created using distant supervision techniques also have some false negative relations that constitute undocumented/unknown relations (missing from a knowledge base). We propose to improve the distinction between these concepts, by revising a subset of the relations marked as false on the phenotype-gene relations corpus and give the first steps to automatically distinguish between the false (F), negative (N), and unknown (U) results. Our work resulted in a sample of 127 manually annotated FNU relations and a weighted-F1 of 0.5609 for their automatic distinction. This work was developed during the 6th Biomedical Linked Annotation Hackathon (BLAH6).

Objective: When multiple surveillance mammograms are performed within an annual interval, the current guidance for oneyear follow-up to determine breast cancer status results in shared follow-up periods in which a single breast cancer diagnosis can be attributed to multiple preceding examinations, posing a challenge for standardized performance assessment. We assessed the impact of using follow-up periods that eliminate the artifactual inflation of second breast cancer diagnoses. Materials and Methods: We evaluated surveillance mammograms from 2007–2016 in women with treated breast cancer linked with tumor registry and pathology outcomes. Second breast cancers included ductal carcinoma in situ or invasive breast cancer diagnosed during one-year follow-up. The cancer detection rate, interval cancer rate, sensitivity, and specificity were compared using different follow-up periods: standard one-year follow-up per the American College of Radiology versus follow-up that was shortened at the next surveillance mammogram if less than one year (truncated follow-up). Performance measures were calculated overall and by indication (screening, evaluation for breast problem, and short interval follow-up). Results: Of 117971 surveillance mammograms, 20% (n = 23533) were followed by another surveillance mammogram within one year. Standard follow-up identified 1597 mammograms that were associated with second breast cancers. With truncated follow-up, the breast cancer status of 179 mammograms (11.2%) was revised, resulting in 1418 mammograms associated with unique second breast cancers. The interval cancer rate decreased with truncated versus standard follow-up (3.6 versus 4.9 per 1000 mammograms, respectively), with a difference (95% confidence interval [CI]) of -1.3 (-1.6, -1.1). The overall sensitivity increased to 70.4% from 63.7%, for the truncated versus standard follow-up, with a difference (95% CI) of 6.6% (5.6%, 7.7%). The specificity remained stable at 98.1%. Conclusion Truncated follow-up, if less than one year to the next surveillance mammogram, enabled second breast cancers to be associated with a single preceding mammogram and resulted in more accurate estimates of diagnostic performance for national benchmarks.

OBJECTIVES: Despite increasing availability of global positioning system (GPS), no research has been conducted to analyze GPS data for exposure opportunities associated with time at indoor and outdoor microenvironments. We developed location-based and time-weighted spatial measures that incorporate indoor and outdoor time-location data collected by GPS. METHODS: Time-location data were drawn from 38 female subjects in California who wore a GPS device for seven days. Ambient standard deviational ellipse was determined based on outdoor locations and time duration, while indoor time weighted standard deviational ellipse (SDE) was developed to incorporate indoor and outdoor times and locations data into the ellipse measure. RESULTS: Our findings indicated that there was considerable difference in the sizes of exposure potential measures when indoor time was taken into consideration, and that they were associated with day type (weekday/weekend) and employment status. CONCLUSIONS: This study provides evidence that time-location weighted measure may provide better accuracy in assessing exposure opportunities at different microenvironments. The use of GPS likely improves the geographical details and accuracy of time-location data, and further development of such location-time weighted spatial measure is encouraged.

BACKGROUND: There has been no documented data on the prevalence of allergic rhinitis among Filipino adults. OBJECTIVE: The objective of this study is to determine the prevalence of allergic rhinitis among adults in the Philippines. METHODS: Using a multi-staged cluster sampling methodology, this study evaluated 7,202 adults from 3,744 households, 79 provinces and 17 regions. A pre-validated written questionnaire for allergic rhinitis based on the International Study of Asthma and Allergies of Childhood was used as the survey instrument. RESULTS: The response rate obtained from the interview was 94.1%. The overall prevalence of nose symptoms in the past 12 months was 20% while prevalence of nose symptoms at any time in the past was 23.8%. The proportion among both sexes was similar. The prevalence was highest among the respondents 40-49 years old. The overall prevalence of nose and eye symptoms for the past twelve months was 14.0%. The prevalence of respondents who reported presence of nose problems for the past twelve months was similar across the 12 months of the year with highest rates noted in the months of June and May. Respondents from the rural area (22.1%) reported a higher prevalence of nose symptoms for the past twelve months compared to respondents from urban area (18%). There was no significant difference in prevalence of nose symptoms among residents living in coastal and/or inland areas. CONCLUSION: The overall prevalence of allergic rhinitis in the Philippines based on the 2008 National Nutrition and Health Survey is 20.0%.

Human Immunodeficiency Virus (HIV) epidemic remains a significant burden in Malaysia. Stigma related to HIV and its effect on the quality of life (QOL) of persons living with HIV (PLHIV) remains under-reported. The aim of the present study was to assess self-perceived stigma amongst PLHIV attending an urban community clinic and its influence on their QOL. Data was collected using HIV Stigma Scale and WHO-QOL HIV BREF Scale. The overall stigma experienced by PLHIV in this community was higher than previous studies (mean ± SD; 103.37 ±18.14). Majority participants had fear disclosing their disease status, while personalized stigma or the experience of prejudice and rejection was the least experienced. The overall QOL was low and was significantly impaired in social relationship domain (mean ± SD; 12.72 ± 3.59). However, their ability to perform daily activities was not affected by the illness (mean ± SD; 14.48 ± 2.91). PLHIV with higher spiritual values demonstrate lower perception of negative self-image and inferiority (r= -0.54). This finding was unique to PLHIV in this study and suggested the importance of spirituality and personal beliefs on their self-esteem. In conclusion, stigma remains as a significant problem among PLHIV in this community. Primary care offers the best platform to promote a holistic management of PLHIV, where the integration between counselors, religious experts, family and non-governmental associations could come together. The management of PLHIV is unique in every community, hence individualized approach based on cultural norms and beliefs could assist in the overall management of
