BACKGROUND: Cushing's syndrome is a state of hypercortisolism manifesting non-specific clinical; features where its diagnosis entails biochemical confirmation of cortisol excess. this study aims to validate the efficacy of midnight salivary cortisol as a screening test for Filipino suspected with Cushing's syndrome and determine the cut-off value applicable in the local setting.
METHODS: This is a cross-sectional study of Filipinos suspected with endogenous Cushing's syndrome seen at a tertiary hospital. Modification of plasma cortisol measured by RIA was used to measure salivary cortisol. The sensitivity, specificity, positive predictive curve, negative predictive curve and area under the screening tests were estimated and compared using 48 hour low dose dexamethasone suppression test (LDDST) as the reference standard.
RESULTS: The determine cut-off value (? 7.0 nmol/L) for salivary cortisol showed a relatively high sensitivity (91.3%) and specificity (89.5%) in detecting cases suspected of Cushing's syndrome. One milligram (1mg) dexamethasone suppression test had the highest sensitivity (100%) but had the lowest specificity (68.4%) as a screening test. The area under the curve of the three diagnostic test appeared to be similar when compared with the low dose dexamethasone suppression test.
CONCLUSIONS: Using a cut-off value of 7nmol/L, local utility if late-night salivary cortisol has a high sensitivity and specificity in detecting Cushing's syndrome. It has a similar efficiency with 24-hour urine free cortisol and 1mg dexamethasone suppression test as a screening test for Cushing's syndrome. Salivary cortisol may be considered as a valid initial screening test for Filipinos suspected of cushing's syndrome.

OBJECTIVE: To describe the demographic and stress profile of the participants in the LIFECARE cohort.
METHODS: The Life Course Study in Cardiovascular Disease Epidemiology (LIFECARE) is a community-based prospective cohort of apparently healthy individuals aged 20 to 50 years old with no preexisting cardiovascular disease. The second phase out of four phases of study involves collection of baseline socio-demographic, anthropometric, biochemical and cardiovascular parameters and stress profiles. It was conducted via face-to-face interview using a survey questionnaire.
RESULTS AND CONCLUSION: A total of 3072 participants from Metro Manila and 4 provinces in Luzon were recruited. The female to male ratio was 1.3:1. Majority of the participants were aged 30 years old and above. Most were married, employed and literate. Majority attained at least high school level of education. Loss of job was the most common stressor experienced in the past year. Majority of the cohort reported occasional experience of general stress and moderate level of financial stress. Occurrence of general stress within the past year was higher among females (p < 0.001), younger age-group (p=0.006), and among those who reached college level of education (p<0.001). Furthermore, level of current financial stress was high to severe among older age-group (p=0.004), and among widow/widower/separated (p<0.0001). While the relationship between psychosocial stress and physical illness had not been established in this study, there is a need to investigate demographics and psychosocial stress, and their implications in increasing adverse health outcomes in general, and cardiovascular risk in particular.

OBJECTIVE: This study aims to describe the socio-ecological and health profile of the Philippine LIFECARE study sites, its health care services and leading causes of mortality and morbidity.
METHODS: This is a prospective cohort study that recruited participants aged 20-50 years from Metro Manila and four provinces (Bulacan, Batangas, Quezon, Rizal). Study sites were characterized according to their geographical area, terrain and environmental profile, and available health care system.
RESULTS: 3,072 subejects were included, with male-to-female ratio of 1:1.3 and majority aged 30-50 years. Metro Manila was the most congested site. Two-thirds of the 62 villages (barangays) were rural, outside the town proper, and in lowlands. One-fourth were along coastal area. Almost all were accessible by public transportation. Majority have reduced forest cover, but were relatively safe from environmental hazards. Rural health units, hospitals, and professional health care workers were concentrated in Metro Manila. Leading cause of morbidity was respiratory tract infection, while cardiovascular diseases caused most of mortalities.
CONCLUSION: Study sites were mainly rural, outside the town proper and in lowlands, with available public transportation. There is an unequal distribution of health resources. Cardiovascular diseases is still the leading cause of mortality. The disparities in geographical access to health care play an important role in shaping human health.

OBJECTIVE: To describe the distribution of the clinical cardiovascular risk profile of the LIFECARE Philippine cohort in relation to its socio-demographic factors.
METHODS: We recruited a total of 3,072 apparently healthy participants from Manila and nearby provinces of Rizal, Batangas, Bulacan and Quezon. Face-to-face interview was done to obtain socio-demographic data. Baseline clinical parameters and biochemical tests were obtained. Prevalence of cardiovascular risk factors was determined by sex, place of residence, level of education and employment.
RESULTS: Overall prevalence of diabetes mellitus was at 5%, similar between sexes, area class, educational attainment and employment status. More smokers were male, employed or with an elementary level of education. Prevalence of hypertension was at 14.5% and was seen more in males, urban dwellers, employed or with an elementary level of education. Dyslipidemia was seen more in males, living in the rural areas, employed or with a college level of education. Lastly, obese participants were seen more in females, living in urban areas, employed with a college level of eduction.
CONCLUSION: Older, male and employed participants who are living in the urban areas have more cardiovascular risk factors.
