RESUMEN

Purpose Cervical cancer is an important cause of mortality in low- and middle-income countries. Although screening technologies continue to improve, systems of care remain fragmented. It is important to better understand factors that affect use of screening services and loss to follow-up along the care continuum. Methods We conducted a mixed-methods study of a cytology-based screening program in rural Guatemala. A retrospective electronic chart review was performed on data from all patients from 2013 to 2014. We analyzed progression through care and calculated loss-to-follow-up rates. We also analyzed the prior experiences of patients with cervical cancer screening on the basis of self-reported historical data available in the chart review. Structured interviews with a subset of individuals to explore social supports and barriers to screening and engagement in care were conducted at the time of screening. Results The analysis included 515 women (median age, 36 years). Cytologic screening showed concern for neoplastic changes in 0.83%; half resulted in biopsy-proven cervical intraepithelial neoplasia. An additional 9.9% showed severe inflammation. The rate of loss to follow-up was 11.3%. All losses to follow-up occurred for severe inflammation, not for cervical intraepithelial neoplasia. Historical data showed that 73% of the cohort had previously been screened and had high levels of loss to follow-up (57.4%). Qualitative interviews revealed factors that promoted loss to follow-up; these included cost, lack of social supports, transportation, distrust in public facilities, long turn-around times, and failure to return test results or offer follow-up treatments. Conclusions Taken together, these quantitative and qualitative results highlight the need for cervical cancer screening programs in Guatemala to improve uptake of screening services by eligible women and to improve follow-up after a first abnormal screen.

RESUMEN

Limited funding for medical technology, low levels of education and poor infrastructure for delivering and maintaining technology severely limit medical decision support in low- and middle-income countries. Perinatal and maternal mortality is of particular concern with millions dying every year from potentially treatable conditions. Guatemala has one of the worst maternal mortality ratios, the highest incidence of intra-uterine growth restriction (IUGR), and one of the lowest gross national incomes per capita within Latin America. To address the lack of decision support in rural Guatemala, a smartphone-based system is proposed including peripheral sensors, such as a handheld Doppler for the identification of foetal compromise. Designed for use by illiterate birth attendants, the system uses pictograms, audio guidance, local and cloud processing, SMS alerts and voice calling. The initial prototype was evaluated on 22 women in highland Guatemala. Results were fed back into the refinement of the system, currently undergoing RCT evaluation.

RESUMEN

BACKGROUND: Argininemia is rare inborn error of metabolism which, when untreated, presents in late infancy with growth delay and developmental regression. In developed countries, argininemia is diagnosed early by newborn screening and is treated immediately with a protein-restricted diet. In developing countries, diagnosis may be delayed by the assumption that stunting is related to malnutrition alone. CASE PRESENTATION: We describe the diagnosis and treatment of argininemia in a 60-month-old Kaqchikel Maya girl in rural Guatemala. The patient initially presented with severe stunting and developmental regression. The initial diagnosis of argininemia was made by a screening test in dried blood spots and confirmed with urine and serum amino acid profiles. The patient was treated with a low-protein diet using locally available foods, leading to significant improvement in her growth and development. CONCLUSIONS: This case demonstrates that the identification, diagnosis and treatment of IEM in developing countries are increasingly feasible, as well as ethically imperative. Providers working with malnourished children in developing countries should suspect IEM in malnourished children who do not respond to standard therapies.
