SMS for Life: a pilot project to improve anti-malarial drug supply management in rural Tanzania using standard technology

Background: Maintaining adequate supplies of anti-malarial medicines at the health facility level in rural sub-Saharan Africa is a major barrier to effective management of the disease. Lack of visibility of anti-malarial stock levels at the health facility level is an important contributor to this problem. Methods: A 21-week pilot study, 'SMS for Life', was undertaken during 2009-2010 in three districts of rural Tanzania, involving 129 health facilities. Undertaken through a collaborative partnership of public and private institutions, SMS for Life used mobile telephones, SMS messages and electronic mapping technology to facilitate provision of comprehensive and accurate stock counts from all health facilities to each district management team on a weekly basis. The system covered stocks of the four different dosage packs of artemether-lumefantrine (AL) and quinine injectable. Results: Stock count data was provided in 95% of cases, on average. A high response rate (≥ 93%) was maintained throughout the pilot. The error rate for composition of SMS responses averaged 7.5% throughout the study; almost all errors were corrected and messages re-sent. Data accuracy, based on surveillance visits to health facilities, was 94%. District stock reports were accessed on average once a day. The proportion of health facilities with no stock of one or more anti-malarial medicine (i.e. any of the four dosages of AL or quinine injectable) fell from 78% at week 1 to 26% at week 21. In Lindi Rural district, stock-outs were eliminated by week 8 with virtually no stock-outs thereafter. During the study, AL stocks increased by 64% and quinine stock increased 36% across the three districts. Conclusions: The SMS for Life pilot provided visibility of anti-malarial stock levels to support more efficient stock management using simple and widely available SMS technology, via a public-private partnership model that worked highly effectively. The SMS for Life system has the potential to alleviate restricted availability of anti-malarial drugs or other medicines in rural or under-resourced areas

Limited resources restrict the provision of adequate neonatal respiratory care in the countries of Africa

Aim Over two thirds of newborn deaths occur in Africa and South Asia, and respiratory failure is a major contributor of these deaths. The exact availability of continuous positive airway pressure (CPAP) and surfactant in Africa is unknown. The aim of this study was to describe the availability of newborn respiratory care treatments in the countries of Africa. Methods Surveys, in English, French and Portuguese, were sent to neonatal leaders in all 48 continental countries and the two islands with populations over 1 million. Results Forty-nine (98%) countries responded. Twenty-one countries reported less than 50 paediatricians, and 12 countries had no neonatologists. Speciality neonatal nursing was recognised in 57% of countries. Most units were able to provide supplemental oxygen. CPAP was available in 63% and 67% of the most well-equipped government and private hospitals. Surfactant was available in 33% and 39% of the most well-equipped public and private hospitals, respectively. Availability of CPAP and surfactant was greatly reduced in smaller cities. Continuous oxygen saturation monitoring was only available in 33% of countries. Conclusion The availability of proven life-saving interventions in Africa is inadequate. There is a need to sustainably improve availability and use of these interventions

Carrier frequency of the GJB2 mutations that cause hereditary hearing loss in the Japanese population.

Hearing impairment is one of the most common sensory disorders that affect ~1 in 1000 children, and half of them are considered to be hereditary. Information about the carrier frequencies of mutations that underlie autosomal recessive disorders is indispensable for accurate genetic counseling to predict the probability of patients' children's disease. However, there have been few reports specific to the Japanese population. GJB2 mutations are reported to be the most frequent cause of hereditary hearing loss, and the mutation spectrum and frequency of GJB2 mutations were reported to vary among different ethnic groups. In this study, we investigated the carrier frequency of GJB2 mutations and the mutation spectrum in 509 individuals randomly selected from the general Japanese population. We show that the carrier frequencies of the two most common pathogenic mutations are 1.57% (8/509) for c.235delC and 1.77% (9/509) for p.Val37Ile. In addition to these mutations, we found two pathogenic variants (p.[Gly45Glu;Tyr136*] and p.Arg143Trp), and the total carrier frequency was estimated to be around 3.73% (19/509). We also detected six unclassified variants, including two novel variants (p.Cys60Tyr and p.Phe106Leu), with the former predicted to be pathogenic. These findings will provide indispensable information for genetic counseling in the Japanese population
