Amniotic fluid (AF) is a dynamic medium that plays a significant role in fetal well-being. It is production and amount varies with gestational age. It plays a vital role in fetal life as it contains antimicrobial factors, growth factors and it help the fetal lung to grow and expand. Amnioinfusion can be performed either transabdominally or transvaginal. Amnioinfuion can be done antenatally and during labor. Aminoinfusion can be used for diagnostic purposes to enable better visualization of the fetus as liquor is very important acoustic widow for better fetal examination. Amnioinfusion have some therapeutic benefits in conditions like early premature rupture of membrane and may help cases of external cephalic version for breech presentation at term. Amnioinfusion has been shown to reduce the incidence of variable deceleration due to cord compression, reduces the risk of meconium aspiration and it will help reduce cesarean delivery. 相似文献

The integration within existing health care systems of preventive initiatives to maintain independent living among older people is increasingly emphasized. This article describes the development and refinement of the [G]OLD home visitation programme: an eight-step programme, including a comprehensive geriatric assessment, for the early detection of health and well-being problems among older people (≥75 years) by general practices. A single group post-test study using a mixed model design is performed to evaluate (a) the feasibility of the home visitation programme in general practice, (b) the practical usefulness of the geriatric assessment instrument, and (c) programme implementation with respect to reinventions introduced by general practitioners (GPs) and practice nurses (PNs). Within 3 months time, 22 PNs of 18 participating general practices visited 240 community-dwelling older people (mean age = 82.0 years; SD 4.2) who had not been in contact with their general practice for more than 6 months. Mean time investment of the programme per older person was 118.1 min (SD 27.0) for GPs and PNs combined. Evaluation meetings revealed that GPs and PNs considered the home visitation programme to be feasible in daily practice. They judged the geriatric assessment to be useful, although minor adjustments are needed (e.g., lay-out, substitution of tests). PNs often failed to register follow-up actions for detected problems in a care and treatment plan. Future training for PNs should address this issue. No reinventions were introduced that threatened fidelity of implementation. The findings are used to improve the home visitation programme before its evaluation in a large-scale controlled trial. 相似文献

The maintenance and modulation of cutaneous mast cell (MC) numbers is held to be important for skin immune responses to allergens and pathogens. The increase in MC numbers in the skin is achieved by proliferation and the differentiation of precursor to mature MCs. Fibroblast‐derived SCF is thought to be the major skin MC growth factor and it potently induces MC proliferation. The mechanisms of fibroblast‐induced skin MC differentiation, including the role of SCF, however, remain insufficiently characterized and understood. Using cocultures of immature murine MCs and fibroblasts, we found that the adhesion of immature MCs to fibroblasts via VCAM‐1 and α4β7 integrin is very important for subsequent differentiation, which is driven by fibroblast membrane‐bound SCF and additional fibroblast‐derived membrane‐bound signals. Thus, our results show that fibroblast‐induced MC differentiation is induced by direct cell–cell contact and involves both Kit‐dependent and Kit‐independent pathways. Our findings add to the understanding of how immature mast cells mature in murine skin and encourage further analyses of the underlying mechanisms, which may result in novel targets for the modulation of skin mast cell driven diseases. 相似文献

BackgroundThe prevalence of targeted and serendipitous treatment for, and associated recovery from, urinary tract infection (UTI) in pre-school children is unknown.AimTo determine the frequency and suspicion of UTI in children who are acutely ill, along with details of antibiotic prescribing, its appropriateness, and whether that appropriateness impacted on symptom improvement and recovery.MethodSystematic urine sampling from children aged <5years presenting in primary care with acute illness with culture in NHS laboratories.ResultsOf 6079 children’s urine samples, 339 (5.6%) met laboratory criteria for UTI and 162 (47.9%) were prescribed antibiotics at the initial consultation. In total, 576/7101 (8.1%) children were suspected of having a UTI prior to urine sampling, including 107 of the 338 with a UTI (clinician sensitivity 31.7%). Children with a laboratory-diagnosed UTI were more likely to be prescribed antibiotics when UTI was clinically suspected than when it was not (86.0% versus 30.3%, P<0.001). Of 231 children with unsuspected UTI, 70 (30.3%) received serendipitous antibiotics (that is, antibiotics prescribed for a different reason). Overall, 176 (52.1%) children with confirmed UTI did not receive any initial antibiotic. Organism sensitivity to the prescribed antibiotic was higher when UTI was suspected than when treated serendipitously (77.1% versus 26.0%; P<0.001). Children with UTI prescribed appropriate antibiotics at the initial consultation improved a little sooner than those with a UTI who were not prescribed appropriate antibiotics initially (3.5 days versus 4.0 days; P = 0.005).ConclusionOver half of children with UTI on culture were not prescribed antibiotics at first presentation. Serendipitous UTI treatment was relatively common, but often inappropriate to the organism’s sensitivity. Methods for improved targeting of antibiotic treatment in children who are acutely unwell are urgently needed. 相似文献

BackgroundSymptoms are important drivers for the use of primary care services. Strategies aimed at shifting the focus away from the GP have broadened the range of primary healthcare available.AimTo explore preferences for managing symptoms and investigate trade-offs that the public are willing to make when deciding between different primary care services.MethodA discrete choice experiment examined management preferences for three symptoms of differing seriousness (diarrhoea, dizziness, and chest pain). Willingness-to-pay estimates compared preferences between symptoms, and by sex, age, and income.ResultsPreferences differed significantly between symptoms. ‘Self-care’ was the preferred action for diarrhoea and ‘consulting a GP’ for dizziness and chest pain. ‘Waiting time’ and ‘chance of a satisfactory outcome’ were important factors for all three symptoms, although their relative importance differed. Broadly, people were more prepared to wait longer and less prepared to trade a good chance of a satisfactory outcome for symptoms rated as more serious. Generally, preferences within subgroups followed similar patterns as for the whole sample, although there were differences in the relative strength of preferences.ConclusionDespite increased choices in primary care, ‘traditional’ actions of ‘self-care’ for minor symptoms and ‘GP consultation’ for more serious symptoms were preferred. The present findings suggest, however, that people may be willing to trade between different health services, particularly for less serious symptoms. Understanding the relative importance of different factors may help inform interventions aimed at changing management behaviour or improving services. 相似文献
