Aim: To describe gut colonization in preterm infants using standard culture and 16S gene rRNA profiling, exploring differences in healthy infants and those who developed NEC/late onset sepsis (LOS). Methods: Ninety‐nine stools from 38 infants of median 27‐week gestation were cultured; 44 stools from 27 infants had their microbial profiles determined by 16S. Ordination analyses explored effects of patient variables on gut communities. Results: Standard microbiological culture identified a mean of two organisms (range 0–7), DGGE 12 (range 3–18) per patient. Enterococcus faecalis and coagulase negative staphylococci (CONS) were most common by culture (40% and 39% of specimens). Meconium was not sterile. No fungi were cultured. Bacterial community structures in infants with NEC and LOS differed from healthy infants. Infants who developed NEC carried more CONS (45% vs 30%) and less Enterococcus faecalis (31% vs 57%). 16S identified Enterobacter and Staphylococcus presence associated with NEC/LOS, respectively. Conclusions: Important differences were found in the gut microbiota of preterm infants who develop NEC/LOS. The relationship of these changes to current practices in neonatal intensive care requires further exploration. 相似文献

Background
Selective serotonin reuptake inhibitors (SSRIs), a popular class of antidepressants, may increase breast cancer risk by stimulating the secretion of prolactin, a potential tumour promoter. We evaluated the effects of duration of SSRI use, cumulative dose, and latency on the risk of breast cancer by conducting a population-based case-control study utilizing Saskatchewan health databases. 相似文献43.
The first permanent molar (FPM) is commonly subject to significant compromise which may arise due to caries or endodontic complication, or from developmental anomalies such as hypoplasia. Compromised teeth with questionable prognosis may result in short and long-term clinical dilemmas. This review article highlights the factors that require careful consideration when a compromised FPM is detected and the importance of timely FPM extraction. Several clinical cases are described in detail to discuss possible treatment options from the orthodontic perspective. 相似文献

Psychiatric morbidity has been shown to be associated with the increased reporting of a range of social problems involving legal rights (‘rights problems’). Using a validated measure of psychiatric morbidity, this paper explores the relationship between psychiatric morbidity and rights problems and discusses the implications for the delivery of health and legal services. New representative national survey data from the English and Welsh Civil and Social Justice Survey (CSJS) surveyed 3040 adults in 2007 to explore the relationship between GHQ‐12 scores and the self reported incidence of and behaviour surrounding, rights problems. It was found that the prevalence of rights problems increased with psychiatric morbidity, as did the experience of multiple problems. It was also found the likelihood of inaction in the face of problems increased with psychiatric morbidity, while the likelihood of choosing to resolve problems without help decreased. Where advice was obtained, psychiatric morbidity was associated with a greater tendency to obtain a combination of ‘legal’ and ‘general’ support, rather than ‘legal’ advice alone. The results suggest that integrated and ‘outreach’ services are of particular importance to the effective support of those facing mental illness. 相似文献

ABSTRACTEnglish is one of eleven official languages in South Africa, but there is limited information on children’s acquisition of English and other languages in this context. This paper describes speech development in 308 children aged 3;0–5;11 acquiring South African English in Cape Town. The study focused on English speech acquisition, although children were grouped by language background into monolingual, isiXhosa bilingual, Afrikaans bilingual and trilingual groups. The primary objective was to describe phonetic and phonological acquisition (percentage consonants and vowels correct (PCC and PVC); phonetic inventory and phonological processes) by children’s age and language background. As a secondary objective we described the prevalence of speech disorders in the sample using Dodd’s (2005) framework. The Diagnostic Evaluation of Articulation and Phonology was used to assess participants with modified scoring criteria appropriate for the context. Phonological processes and inventories were broadly comparable to normative data for English speech acquisition documented in the literature, and a progression was observed with increasing age. PCC and PVC were similar for children within age bands despite different language backgrounds. Bilingual children showed aspects of English phonological development linked to their L1, and some differences in phonological processes were observed. Approximately 9% of children (n = 28) had speech difficulties, with 75% of this group having a speech delay. The study highlights the importance of adapting speech assessments for use with populations that differ from the originally intended audience. This work contributes to knowledge of typical speech development in South Africa and in multilingual contexts more generally. 相似文献
