Objective To analyse, on the basis of the literature, the potential of mobile phones to improve maternal health services in Low and Middle Income Countries (LMIC). Methods Wide search for scientific and grey literature using various terms linked to: maternal health, mobile telecommunication and LMIC. Applications requiring an internet connection were excluded as this is not widely available in LMIC yet. Results Few projects exist in this field and little evidence is available as yet on the impact of mobile phones on the quality of maternal health services. Projects focus mainly on the delay in receiving care – that is in recognizing the need and making the decision to seek care – and the delay in arriving at the health facility. This is achieved by connecting lesser trained health workers to specialists and coordination of referrals. Ongoing projects focus on empowering women to seek health care. Discussion There is broad agreement that access to communication is one of several essential components to improve maternal health services and hence the use of mobile phones has much potential. However, there is a need for robust evidence on constraints and impacts, especially when financial and human resources will be invested. Concurrently, other ways in which mobile phones can be used to benefit maternal health services need to be further explored, taking into consideration privacy and confidentiality. 相似文献

We have recently reported reduced telomere length in T lymphocytes of individuals with Down syndrome (DS) and dementia due to Alzheimer's disease (AD). We have now replicated and extended that study by finding that people with DS and mild cognitive impairment (MCI-DS) also have shorter telomeres than people with DS without MCI-DS. Additional new findings demonstrated that light intensity measurements from chromosome 21 alone, or in concert with chromosomes 1, 2, and 16, exhibited shorter telomeres in adults with DS and with either dementia or MCI-DS compared to aging per se. Chromosome 21 measurements appeared to be especially promising for use as a biomarker because there was no overlap in the distribution of light intensity measurement scores between demented or MCI-DS and non-demented participants. Given that early clinical symptoms of AD can be very difficult to recognize in this population of adults due to their pre-existing cognitive impairments, a valid biomarker would be of great value. Early detection is especially important because it would allow treatments to begin before significant damage to the central nervous system has occurred. Our findings suggest that it may be feasible to use telomere shortening as a biomarker for accurately inferring dementia status. 相似文献

These guidelines for the management of patients up to 18 years with Langerhans cell histiocytosis (LCH) have been set up by a group of experts involved in the Euro Histio Net project who participated in national or international studies and in peer reviewed publications. Existing guidelines were reviewed and changed where new evidence was available in the literature up to 2012. Data and publications have been ranked according to evidence based medicine and when there was a lack of published data, consensus between experts was sought. Guidelines for diagnosis, initial clinical work‐up, and treatment and long‐term follow‐up of LCH patients are presented. Pediatr Blood Cancer 2013;60:175–184. © 2012 The Authors.

BACKGROUND: Bone marrow changes and their relation to blood cytopenia in patients with Langerhans cell histiocytosis (LCH) have not been extensively studied to date. The aim of the present study was to characterize the bone marrow changes in LCH patients and to ascertain their relation to disease severity. METHODS: Fifty-seven marrow samples of LCH patients were studied by conventional cytology, immunocytochemistry (ICC) and flow cytometry (FCM). RESULTS: On conventional cytology there was no significant difference between LCH cases and controls with respect to cellularity, number of monocytes and progenitor cells, and presence of histiocytes and hemophagocytosis. The numbers of nucleated cells, CD34(pos) cells, and CD14(pos) cells on FCM did not differ, either. The CD1a staining by ICC was positive in 14/41 LCH samples, and was consistently negative in controls. FCM staining for CD1a was positive in 12/54 samples, but also in 5/35 controls. The number of the CD1a(pos) cells in LCH marrows was usually very low (<10-20 cells/slide by ICC, or <0.5% of the leukocytes by FCM). The CD1a staining was more frequently positive and more pronounced in patients with severe disease. CONCLUSIONS: The combination of conventional aspirate cytology with ICC (CD1a staining) appears to be the most reliable tool for bone marrow assessment in LCH. 相似文献

Autism Spectrum Disorder (ASD) presents pervasive challenges for individuals throughout their lifetime. Although some financial, community, and individual supports are available for children, there are fewer resources available for adults with ASD, their families, and/or caregivers. It is important to understand the multidimensional shifts associated with the transition from adolescence to adulthood for individuals with ASD. To better understand the transitional process, a qualitative study comprised 11 semi-structured interviews with individuals with ASD and their families. Interviews elicited the experiences of individuals and families impacted by ASD as they transition to adulthood and adult systems of care. This study found that individuals with ASD and their family are exposed to a “lifetime of difficult transitions” due to a limited number of service providers and resources including stringent and restrictive program and funding criteria. As a result, individuals with ASD and their families were concerned about the ability of some individuals with ASD to establish meaningful lives in adulthood. These findings challenge existing barriers and broader societal values and stigma that impede emerging adults with developmental disabilities. 相似文献

First representatives of a new family of isoquinolines, so called boroisoquinolines, were synthesized and characterized. The synthesis was based on the insertion of the difluoroboranyl group into the 1-methylidene-3,4-dihydroisoquinoline core. The optimization of the 2-difluoroboranyl-3,4-dihydroisoquinoline-1(2H)-ylidene core led to efficient fluorescence in a range of 400–600 nm with outstanding (>100 nm) Stokes shifts. The compounds might be suitable for reversible or irreversible labelling of proteins, particularly the cannabinoid receptor CB2.First representatives of a new family of isoquinolines, so called boroisoquinolines, were synthesized and characterized. 相似文献

Skeletal involvement is generally, but not universally, characteristic of Langerhans cell histiocytosis (LCH). We investigated whether the presence of bone lesions at diagnosis is a prognostic factor for survival in LCH. Nine hundred and thirty‐eight children with multisystem (MS) LCH, both high (386 RO+) and low (RO?) risk, were evaluated for bone lesions at diagnosis. Risk organ (RO+) involvement was defined as: haematopoietic system (haemoglobin <100 g/l, and/or white blood cell count <4·0 × 109/l and/or platelet count <100 × 109/l), spleen (>2 cm below the costal margin), liver (>3 cm and/or hypoproteinaemia, hypoalbuminaemia, hyperbilirubinaemia, and/or increased aspartate transaminase/alanine transaminase). Given the general view that prognosis in LCH worsens with increasing extent of disease, the surprising finding was that in MS+RO+ LCH the probability of survival with bone involvement 74 ± 3% (n = 230, 56 events) was reduced to 62 ± 4% (n = 156, 55 events) if this was absent (P = 0·007). An even greater difference was seen in the subgroup of patients with both liver and either haematopoiesis or spleen involvement: 61 ± 5% survival (n = 105; 52 events) if patients had bony lesions, versus 47 ± 5% (n = 111; 39 events) if they did not (P = 0·014). This difference was retained in multivariate analysis (P = 0·048). Although as yet unexplained, we conclude that bone involvement at diagnosis is a previously unrecognized favourable prognostic factor in MS+RO+ LCH. 相似文献
