A case study of the long-term sustainability of an oral health program for persons experiencing homelessness

Stakeholders engaged in funding health programs and investing in human capital are concerned that their investments lead to beneficial long-term outcomes and do not fade from existence when funding streams dry up. However, dissemination and implementation researchers often pay little attention to what happens after programs are implemented. An essential function of the public health nurse operating at the executive management or leadership level is to evaluate overall effectiveness, quality, and sustainability of programs and to design systems-level quality initiatives and evaluation plans that foster program sustainability. This article applies a conceptual framework for sustainability to an oral health program serving persons experiencing homelessness, exploring the essential programmatic, community, and organizational factors that have positively impacted the long-term sustainability of the program. Lessons learned from a model program that has thrived in a political and economic resource poor climate may assist the public health nurse in planning and developing health programs that can withstand the test of time even in the most challenging of circumstances.

Contemporary Childbirth Education Models

Since the 1960s, childbirth education advocates have attempted to persuade pregnant women that educational preparation for labor and birth is an essential component of the transition to motherhood. Initially, pregnant women who were seeking unmedicated births as a refuge from the inhumane childbirth treatments of the mid‐20th century embraced this view. However, with the changing childbirth climate, including a growing preference for medicated birth, scheduled inductions, and cesarean sections, attendance has diminished and childbirth education finds itself at a crossroads. Commonly used childbirth education models/organizations and several new emerging models along with the available research literature and recommendations for clinical practice and research are presented.     

Calcium and phosphorus contents of body parts of some domestic animals used as meat source in Nigeria

ObjectiveTo investigate the calcium and phosphorus contents of four domestic animals used as sources of meat in Nigeria.MethodsThe calcium contents of the body parts of the animals were determined using atomic absorption spectrometer. Their phosphorus contents were determined colorimetrically using the molybdenum blue method.ResultsThe calcium and phosphorus contents were significantly higher in the bone samples than in the other animal parts investigated (P<0.05). The calcium contents of all the edible parts were higher in chicken than in the other animals. High calcium and phosphorus contents were detected in the faeces of chicken and goat, and that of cattle and goat, respectively. Low calcium and phosphorus contents were detected in the urine samples. Calcium: phosphorus ratios calculated for the bones of chicken, cattle and goat were satisfactory.ConclusionsIn conclusion, calcium and phosphorus contents of the animal parts vary significantly and their relative contents may be related to the animal's diet. Chicken parts may be the preferred dietary source of these minerals. This study highlights the need for routine investigation of the mineral contents of food, which is necessary for proper nutritional guidelines.
