OBJECTIVE: Dengue fever remains a public health problem in the Philippines. Eliminating key container artificial breeding sites of mosquito vectors is a vital part of dengue control. The objective of this descriptive cross-sectional study was to conduct an entomological survey of artificial container breeding sites of Aedes mosquitoes in households of two puroks in Batasan Hills, Quezon City.
METHODS: All potential artificial container breeding sites of dengue in each household were inspected for mosquito larvae. Water was sampled from all containers that had mosquito larvae. Water was sampled from all containers that had mosquito larvae and the larval species determined through microscopic examination. Using the World Health Organization list of recognized containers, each container was classified as recognized or an unrecognized container.
RESULTS: The larval indices computed were: container index = 6.4%, household index = 23.9% and Breteau index = 29%. The proportion of containers positive for A. aegypti larvae was significantly higher for the unrecognized containers (9.9%) than that of the recognized containers (3.9%) (p=0.002).
CONCLUSION: The high household index and Breteau index indicate that the potential for dengue transmission is high in the study area. Unrecognized artificial containers contributed significantly to the number of Aedes breeding sites. "Search-and-destroy" campaigns in the community should be expanded to include these containers. Crafting specific vector control messages that address the problem of particular unrecognized containers as well as those of recognized containers with the highest proportion positive for Aedes larvae will also aid dengue control and prevention. Repeat surveys to monitor larval indices may be used to help ascertain the effectiveness of these messages in decreasing mosquito breeding sites.

OBJECTIVE: Malaria is a life-threatening, mosquito-borne disease that continues to cause numerous deaths worldwide. In the Philippines, malaria remains an important problem, with five provinces having >1000 cases of malaria a year. The objective of this cross-sectional analytical study was to determine the association of selected factors with non-compliance to anti-malarial treatment among malaria patients in Puerto Princesa, Palawan, specifically: perceived susceptibility to malaria, perceived seriousness and severity of malaria, perceived benefits of medication, perceived barriers to treatment compliance and cues to action.
METHODS: Using an interviewer-administered structured questionnaire, 320 individuals diagnosed with and treated for malaria from January to October 2010 were interviewed regarding compliance to anti-malarial treatment and the factors related to compliance. Descriptive statistics and multiple logistic regression were used to analyze the data.
RESULTS: The rate of non-compliance to anti-malaria treatment was 17% (95% Cl 12.1%-21.2%). After multivariate analysis using logistic regression, symptom perception as a cue to action and forgetfulness as a perceived barrier to treatment compliance were found to be significantly associated with non-compliance to treatment. The odds of non-compliance were three times higher for individuals who perceived that an improvement in symptoms implied cure of malaria. An individual who forgot to take at least one dose of medication was 17 times more likely to be non-compliant with treatment compared to someone who did not forget to take a single dose.
CONCLUSION: Given the factors found to be associated with noncompliance to treatment, more effective ways of ensuring compliance with anti-malaria treatment may be explored e.g., doing directly observed treatment and utilizing treatment partners that may help address the problem of forgetfulness. The fact that symptom improvement is not equivalent to cure must be stressed when advising patients. Emphasizing compliance to treatment and the consequences of noncompliance when conducting patient education activities may also help boost treatment compliance.

Background:
Tuberculous arthritis is a rare extra-pulmonary manifestation of tuberculosis (TB) that can lead to significant disability when left untreated. This study described the clinical profile of patients with TB arthritis admitted in a tertiary hospital in the Philippines.
Methods:
We reviewed medical records of 65 patients with TB arthritis admitted in the Philippine General Hospital from 2006 to 2019.
Results:
Majority of patients were male (41, 63.0%) and the mean age upon diagnosis was 46.7 ± 1.7 years (20– 85). Majority (33, 50.8%) had underlying co-morbidities including hypertension (16, 24.6%), type 2 diabetes mellitus (10, 15.4%), and chronic kidney disease (8, 12.3%). A history of previous TB treatment (10, 15.4%), intake of immunosuppressive drugs (7, 10.8%), and trauma on affected joints (13, 20.0%) were also reported. Majority presented with chronic mono-arthritis (50, 76.9%) involving the knees (27, 41.5%) and hips (21, 32.3%) with a mean duration of symptoms of 20.9 ± 3.9 months. The most frequent initial diagnosis upon admission was septic arthritis (21, 32.3%). Confirmed septic arthritis (10, 15.6%), pulmonary TB (9, 14.3%), and disseminated TB (4, 6.3%) were also observed. Majority were diagnosed based on positive acid-fast bacilli (AFB) smear, polymerase chain reaction (PCR) for Mycobacterium tuberculosis, or synovium biopsy (34, 54.0%). Anemia (43, 68.3%) and elevated inflammatory biomarkers (erythrocyte sedimentation rate, ESR [36, 97.3%] and C-reactive protein, CRP [40, 87%]) were also seen in majority of patients. The most common radiographic findings on x-ray were joint space narrowing (42, 84.0%), soft tissue swelling (22, 44.0%), and erosions (21, 42.0%). The mean length of hospital stay was 23.8 ± 2.8 days (2–113). Majority underwent surgical interventions (35, 55.6%) including debridement (28, 80.0%) and arthrotomy (25, 71.4%). All received anti-tuberculosis treatment upon diagnosis.
Conclusion
Majority of patients with TB arthritis in this study were male, with mean age in the 5th decade of life, presenting with mono-arthritis, anemia, elevated inflammatory markers, and radiologic findings of joint narrowing. All patients received medical treatment while more than half underwent surgery. There should be a high index of suspicion for TB arthritis in a patient from an endemic country presenting with chronic mono arthritis in weight-bearing joints to prevent delay in diagnosis and significant joint destruction and disability

Objective:
To determine incidence, predictors, and impact of liver injury among hospitalized COVID-19 patients
Methods:
This is a retrospective cohort study of hospitalized COVID-19 patients at the University of the PhilippinesPhilippine General Hospital. Liver injury (LI) was defined as ALT elevation above institutional cut-off (>50 u/L) and was classified as mild (>1x to 3x ULN), moderate (>3x to 5x ULN), or severe (>5x ULN). Significant liver injury (SLI) was defined as moderate to severe LI. Univariate analysis of SLI predictors was performed. The impact of LI on clinical outcomes was determined and adjusted for known predictors -age, sex, and comorbidities.
Results:
Of the 1,131 patients, 565 (50.04%) developed LI. SLI was associated with male sex, alcohol use, chronic liver disease, increasing COVID-19 severity, high bilirubin, AST, LDH, CRP, and low lymphocyte count and albumin. An increasing degree of LI correlated with ICU admission. Only severe LI was associated with the risk of invasive ventilation (OR: 3.54, p=0.01) and mortality (OR: 2.76, p=0.01). Severe LI, male sex, cardiovascular disease, and malignancy were associated with longer hospital stay among survivors.
Conclusion
The liver injury occurred commonly among COVID-19 patients and was associated with important clinicodemographic characteristics. Severe liver injury increases the risk of adverse outcomes among hospitalized patients.

Objectives: To describe the clinical profile and factors associated with mortality among the first 200 patients confirmed to have COVID-19 infection admitted in the University of the Philippines – Philippine General Hospital (UP-PGH)
Methodology: We conducted a retrospective review of adult patients with confirmed COVID-19 infection admitted in PGH, a designated COVID-19 referral center. Demographic, clinical data, and clinical outcomes were extracted from medical records. Frequencies and distributions of various clinical characteristics were described, and factors associated with mortality were investigated.
Results: Of the 200 patients in our cohort, majority were male (55.5%), and more than half (58%) were over 60 years old. Underlying co-morbid illnesses (67.5%) included hypertension (49.5%), diabetes mellitus (26.5%), and cardiovascular disease (20.5%). Most frequent presenting symptoms were cough (69.0%), fever (58.5%), or shortness of breath (53.0%). Most patients presented with mild (n=41, 20.5%) to moderate illness (n=99, 49.5%) and only 60 were considered severely (n=32, 16.0%) or critically ill (n=28, 14.0%). Many (61%) received empiric antibiotics, while 44.5% received either repurposed drugs or investigational therapies for COVID-19. Bacterial co-infection was documented in 11%, with Klebsiella pneumoniae commonly isolated. In-hospital mortality was 17.5%, which was highest for critical COVID-19 (71.4%). Mortality was observed to be higher among patients age 60 and above, those requiring oxygen, ventilatory support and ICU admission, and among those who developed acute kidney injury, acute stroke, sepsis, and nosocomial pneumonia.
Conclusion: Our study confirms that COVID-19 affects males, older individuals and those with underlying co-morbid conditions. Empiric antimicrobial treatment was given for majority of patients, despite documentation of bacterial infection in only 11%. K. pneumoniae was commonly isolated, reflecting local epidemiology. Mortality rate during this early period of the pandemic was high and comparable to other institutions. Factors associated with mortality were related to critical COVID-19 and are similar to other studies.

Acta Medica Philippina 2019;53(4):315-326
Objectives:
This scoping review aimed to support a landscape analysis to identify lessons learned about intersectoral collaborations (ISCs) by describing their existing models in the context of dengue, malaria and yellow fever.
Methods:
A scoping review following the methodology of Joanna Briggs Institute was performed using the following inclusion criteria: studies involving humans; studies discussing intersectoral collaborations, malaria/dengue/yellow fever, and prevention or control at any level; and studies in countries endemic for the aforementioned diseases. Studies were screened using Covidence, while data were extracted using NVivo.
Results:
Of the 7,535 records retrieved, 69 were included in the qualitative analysis. Most ISCs were initiated by multilateral organizations and ministries of health, and none by communities. Strategies included advocacy, health education, research, public health measures, resource mobilization, service delivery and training; mostly employed on a community level. Monitoring and evaluation were mostly formative, ongoing, and participatory. Gaps included administrative and policy barriers, resource shortages, and inadequate research and training.
Conclusions
Multiple models of ISC exist in the literature. There is a need to develop a comprehensive framework for an effective and sustainable multisectoral approach for the prevention and control of VBDs ensuring adequate resources, active stakeholders, and strategies that span the entire socio-ecological spectrum.
