The Community Health Assessment Program in the Philippines (CHAP-P) diabetes health promotion program for low- to middle-income countries: study protocol for a cluster randomized controlled trial.

BACKGROUND: Type 2 diabetes is increasing globally, with the highest burden in low- to middle-income countries (LMICs) such as the Philippines. Developing effective interventions could improve detection, prevention, and treatment of diabetes. The Cardiovascular Health Awareness Program (CHAP), an evidence-based Canadian intervention, may be an appropriate model for LMICs due to its low cost, ease of implementation, and focus on health promotion and disease prevention. The primary aim of this study is to adapt the CHAP model to a Philippine context as the Community Health Assessment Program in the Philippines (CHAP-P) and evaluate the effect of CHAP-P on glycated hemoglobin (HbA1c) compared to a random sample of community residents in control communities. METHODS: Six-month, 26-community (13 intervention, 13 control) parallel cluster randomized controlled trial in Zamboanga Peninsula, an Administrative Region in the southern Philippines. Criteria for community selection include: adequate political stability, connection with local champions, travel feasibility, and refrigerated space for materials. The community-based intervention, CHAP-P sessions, are volunteer-led group sessions with chronic condition assessment, blood pressure monitoring, and health education. Three participant groups will be involved: 1) Random sample of community participants aged 40 or older, 100 per community (1300 control, 1300 intervention participants total); 2) Community members aged 40 years or older who attended at least one CHAP-P session; 3) Community health workers and staff facilitating sessions. PRIMARY OUTCOME: mean difference in HbA1c at 6 months in intervention group individuals compared to control. SECONDARY OUTCOMES: modifiable risk factors, health utilization and access (individual); diabetes detection and management (cluster). Evaluation also includes community process evaluation and cost-effectiveness analysis. DISCUSSION: CHAP has been shown to be effective in a Canadian setting. Individual components of CHAP-P have been piloted locally and shown to be acceptable and feasible. This study will improve understanding of how best to adapt this model to an LMIC setting, in order to maximize prevention, detection, and management of diabetes. Results may inform policy and practice in the Philippines and have the potential to be applied to other LMICs. TRIAL REGISTRATION: ClinicalTrials.gov ( NCT03481335 ), registered March 29, 2018.

Choosing the optimal method of blood pressure measurement for limited-resource rural communities in the "Community Health Assessment Program-Philippines".

The Community Health Assessment Program-Philippines (CHAP-P) is an international collaboration of investigators whose aim is to adapt a previously proven Canadian community-based cardiovascular awareness and prevention intervention to the Philippines and other low-middle-income countries. Choosing a method of blood pressure measurement for the research program presents a challenge. There is increasing consensus globally that blood pressure measurement with automated devices is preferred. Recommendations from low-middle-income countries, including the Philippines, are less supportive of automated blood pressure devices. The value placed on factors including device accuracy, durability, cost, energy source, and complexity differ with local context. Our goal was to support the progress of local policy concerning blood pressure measurement while testing a comprehensive approach to community-based screening for cardiovascular risk. The authors describe the challenges in making a choice of blood pressure device and the approach to determine optimal method of measurement for our research program.

The interplay of Graves' disease and twin molar pregnancy.

Twin molar pregnancy with coexistent viable fetus in a patient with Graves' disease is a rare entity. The patient is a 37-year-old woman who was hospitalised owing to persistent vomiting and vaginal bleeding. The pregnancy test was positive and the pelvic ultrasound disclosed twin gestation of complete mole and a coexistent viable 12-week fetus. ß-Human chorionic gonadotropin (ß-HCG) and free thyroid hormones were both elevated. The patient was also a diagnosed case of Graves' disease prior to this pregnancy. Given the risks for perinatal complications, the patient was offered early termination of pregnancy. She, however, decided to continue her pregnancy and control the hyperthyroidism with an antithyroid drug (ATD). A week after her discharge from the hospital, she had spontaneous abortion and the histopathology of the abortus revealed complete hydatidiform mole and a 13-week fetus.

Papillary thyroid-type carcinoma arising from struma ovarii.

Malignant transformation of benign monodermal teratoma is a rare presentation of struma ovarii. A 41-year-old Filipina presented with 1-year history of recurrent lower abdominal pain, abdominal swelling and vomiting. Ultrasound of the abdomen revealed a large cystic abdomino-pelvic mass densely adherent to the intestinal and uterine wall with moderate ascitis. The patient underwent total abdominal hysterectomy and bilateral salphingo-oophorectomy and histopathology showed papillary thyroid-type carcinoma arising from the left struma ovarii. She underwent total thyroidectomy, postoperative radioactive iodine ablation and maintained on levothyroxine suppressive therapy. She is now on regular follow-up for monitoring of possible tumour recurrence and metastasis.
