RESUMO
BACKGROUND: Maternal nutrition is a determinant of pregnancy outcomes. Few studies have evaluated the potential of online nutrition resources to modify behaviour. This randomized controlled trial aimed to determine whether access to a customized evidence-based nutrition website in pregnancy improved neonatal outcomes. METHODS: Women <18 weeks gestation were recruited at their convenience. The control group received standard care. In addition to standard care, the intervention group received access to an evidence-based nutrition website, customized to the preferences of pregnant women. RESULTS: Of the 250 women, there were no differences in characteristics between the two groups. Of the women, 91.0% reported they make a conscious effort currently to eat a healthy diet. However, only 19.6% met dietary requirements for calcium, 13.2% for iron, 2.7% for folate and 2.3% for iodine. The most popular website section was pregnancy nutrition advice but engagement was not sustained. Access to the website was not associated with any improvement in clinical outcomes (P > 0.05). CONCLUSIONS: We found that provision of a customized website providing nutrition information, did not improve neonatal outcomes. Future studies should explore whether redesign with website interactivity or embedding information on popular digital platforms sustains women's engagement and modifies dietary behaviour.

AIMS: Deciding if a diabetic foot ulcer is infected in a community setting is challenging without validated point-of-care tests. Four inflammatory biomarkers were investigated to develop a composite algorithm for mildly infected diabetic foot ulcers: venous white cell count, C-reactive protein (CRP) and procalcitonin, and a novel wound exudate calprotectin assay. Calprotectin is a marker of neutrophilic inflammation. METHODS: In a prospective study, people with uninfected or mildly infected diabetic foot ulcers who had not received oral antibiotics in the preceding 2 weeks were recruited from community podiatry clinics for measurement of inflammatory biomarkers. Antibiotic prescribing decisions were based on clinicians' baseline assessments and participants were reviewed 1 week later; ulcer infection was defined by clinicians' overall impression from their two assessments. RESULTS: Some 363 potential participants were screened, of whom 67 were recruited, 29 with mildly infected diabetic foot ulcers and 38 with no infection. One participant withdrew early in each group. Ulcer area was 1.32 cm2 [interquartile range (IQR) 0.32-3.61 cm2 ] in infected ulcers and 0.22 cm2 (IQR 0.09-1.46 cm2 ) in uninfected ulcers. Baseline CRP for mild infection was 9.00 mg/ml and 6.00 mg/ml for uninfected ulcers; most procalcitonin levels were undetectable. Median calprotectin level in infected diabetic foot ulcers was 1437 ng/ml and 879 ng/ml in uninfected diabetic foot ulcers. Area under the receiver operating characteristic curve for a composite algorithm incorporating calprotectin, CRP, white cell count and ulcer area was 0.68 (95% confidence intervals 0.52-0.82), sensitivity 0.64, specificity 0.81. CONCLUSIONS: A composite algorithm including CRP, calprotectin, white cell count and ulcer area may help to distinguish uninfected from mildly infected diabetic foot ulcers. Venous procalcitonin is unhelpful for mild diabetic foot ulcer infection.

Background: The World Health Organization recommends that women take 400 µg of folate supplementation daily throughout pregnancy. We examined the relationship between total folate intake from the diet and supplements at the first prenatal visit and haematological indices at this visit and subsequently. Methods: Women were recruited at their convenience and in addition to clinical and sociodemographic details, detailed questionnaires on dietary intakes and supplementation consumption were completed under supervision. A full blood count and serum and red blood cell (RBC) folate levels were taken. Results: Of the 502 women studied, 97.5% had inadequate total dietary folate intake at the first visit, but, 98.2% were taking folic acid (FA) supplementation. Only 1.8% (n = 9) had anaemia at their first visit (with no case of macrocytosis). Subsequently, 212 women had a further Hb sample in the third trimester and 8.5% (n = 18) were anaemic and 43.4% (89/205) were anaemic postnatally. There was a relationship between the development of anaemia postnatally and lower RBC folate levels at the first visit (P = 0.02). Conclusions: In a country where FA food fortification remains voluntary, these findings support the recommendation that women should start FA supplementation before pregnancy and continue FA after the first trimester.

OBJECTIVES: During pregnancy, women are increasingly turning to web-based resources for information. This study examined the use of web-based nutritional information by women during pregnancy and explored their preferences. STUDY DESIGN: Cross-sectional observational study. METHODS: Women were enrolled at their convenience from a large maternity hospital. Clinical and sociodemographic details were collected and women's use of web-based resources was assessed using a detailed questionnaire. RESULTS: Of the 101 women, 41.6% were nulliparous and the mean age was 33.1 years (19-47 years). All women had internet access and only 3% did not own a smartphone. Women derived pregnancy-related nutritional information from a range of online resources, most commonly: What to Expect When You're Expecting (15.1%), Babycenter (12.9%), and Eumom (9.7%). However, 24.7% reported using Google searches. There was minimal use of publically funded or academically supported resources. The features women wanted in a web-based application were recipes (88%), exercise advice (71%), personalized dietary feedback (37%), social features (35%), videos (24%) and cooking demonstrations (23%). CONCLUSIONS: This survey highlights the risk that pregnant women may get nutritional information from online resources which are not evidence-based. It also identifies features that women want from a web-based nutritional resource.

This intervention examined the efficacy of a six-week online weight loss programme. Students and staff of a third level institution (n=183) were recruited to the programme which provided individualised dietary advice for weight loss. Eighty-five participants (mean age 29.7 years, mean BMI 28.9kg/m2, 33% male) met the minimum inclusion criterion of logging on to the study website at least twice. All participants who completed the full six-week programme lost weight (n=31), with significant reductions in mean weight (2.8kg), BMI (0.9kg/m2) and waist circumference (4.1cm) observed between the start and end of the programme (all P<0.001). Among "completers", males lost more weight than females (4.2kg vs. 1.9kg, P=0.004). One in four completers lost >5% of their bodyweight, with reductions in biscuit and alcohol consumption being most predictive of weight loss. These findings suggest that individualised online dietary advice is effective in achieving short-term weight loss, especially in males.

There is international consensus that smoking cessation in the first half of pregnancy improves foetal outcomes. We surveyed all 19 maternity units nationally about their antenatal smoking cessation practices. All units recorded details on maternal smoking at the first antenatal visit. Only one unit validated the self-reported smoking status of pregnant women using a carbon monoxide breath test. Twelve units (63%) recorded timing of smoking cessation. In all units women who reported smoking were given verbal cessation advice. This was supported by written advice in 12 units (63%), but only six units (32%) had all midwives trained to provide this advice. Only five units (26%) reported routinely revisiting smoking status later in pregnancy. Although smoking is an important modifiable risk factor for adverse pregnancy outcomes, smoking cessation services are inadequate in the Irish maternity services and there are variations in practices between hospitals.

UNLABELLED: The scale of genetic-variation datasets has increased enormously and the linkage equilibrium (LD) structure of these polymorphisms, particularly in whole-genome association studies, is of great interest. The significant computational complexity of calculating single- and multiple-marker correlations at a genome-wide scale remains challenging. We have developed a program that efficiently characterizes whole-genome LD structure on large number of SNPs in terms of single- and multiple-marker correlations.

AIMS: To compare the outcomes for trochanteric fractures treated with a sliding hip screw (SHS) or a cephalomedullary nail. PATIENTS AND METHODS: A total of 400 patients with a trochanteric hip fracture were randomised to receive a SHS or a cephalomedullary nail (Targon PFT). All surviving patients were followed up to one year from injury. Functional outcome was assessed by a research nurse blinded to the implant used. RESULTS: Recovery of mobility, as assessed by a mobility scale, was superior for those treated with the intramedullary nail compared with the SHS at eight weeks, three and nine months (p-values between 0.01 and 0.04), the difference at six and 12 months was not statistically significant (p = 0.15 and p = 0.18 respectively). The mean difference was around 0.4 points (0.3 to 0.5) on a nine point scale. Surgical time for the nail was four minutes less than that for the SHS (p < 0.001). Fracture healing complications were similar for the two groups. There were no statistically significant differences between implants for any other recorded outcomes including the need for post-operative blood transfusion, wound healing complications, general medical complications, hospital stay or mortality. CONCLUSION: This study confirms the findings of a previous study that both methods of treatment produce similar results, although intramedullary fixation does result in marginally improved regain of mobility in comparison with the SHS.

Strong evidence that folic acid (FA) prevents the majority of cases of neural tube defects (NTDs) has led to national organisations developing guidelines for women concerning periconceptional supplementation. In Europe, there is evidence of national variations in the incidence of NTDs, with a recent Irish study reporting an increase in the rate. This review compares the periconceptional FA supplementation guidelines between the different countries in Europe. An online search of country-specific guidelines produced before 2015 concerning periconceptional FA supplementation was conducted. If an English version was not available directly, the EUROCAT register was searched for the English version of the recommendations. We identified national guidelines from 20 European countries. Over half recommended that FA supplements be taken by women planning a pregnancy, but three recommended that they should be taken by all women of child-bearing age. Four guidelines recommended starting FA at least 4 weeks preconceptionally, but no country recommended starting FA at least 12 weeks preconceptionally as suggested by recently published studies. There is a need for further consideration of the duration of preconceptional FA supplementation specifically. The latest scientific evidence in this area should inform the development of European guidelines on FA, as there is wide variation in current recommendations. Overall, the wide variation in national guidelines concerning periconceptional FA supplementation may in part explain the differences in national rates of NTDs reported by EUROCAT. National guidelines on FA supplementation should be standardised across European countries.

BACKGROUND: Maternal diet is critical to fetal development and lifelong health outcomes. In this context, dietary quality indices in pregnancy should be explicitly underpinned by data correlating food intake patterns with nutrient intakes known to be important for gestation. AIMS: Our aim was to assess the correlation between dietary quality scores derived from a novel online dietary assessment tool (DAT) and nutrient intake data derived from the previously validated Willett Food Frequency Questionnaire (WFFQ). METHODS: 524 women completed the validated semi-quantitive WFFQ and online DAT questionnaire in their first trimester. Spearman correlation and Kruskal-Wallis tests were used to test associations between energy-adjusted and energy-unadjusted nutrient intakes derived from the WFFQ, and diet and nutrition scores obtained from the DAT. RESULTS: Positive correlations were observed between respondents' diet and nutrition scores derived from the online DAT, and their folate, vitamin B12, iron, calcium, zinc and iodine intakes/MJ of energy consumed derived from the WFFQ (all P < 0.001). Negative correlations were observed between participants' diet and nutrition scores and their total energy intake (P = 0.02), and their percentage energy from fat, saturated fat, and non-milk extrinsic sugars (NMES) (all P ≤ 0.001). Median dietary fibre, beta carotene, folate, vitamin C and vitamin D intakes derived from the WFFQ, generally increased across quartiles of diet and nutrition score (all P < 0.001). CONCLUSIONS: Scores generated by this web-based DAT correlate with important nutrient intakes in pregnancy, supporting its use in estimating overall dietary quality among obstetric populations.

BACKGROUND/OBJECTIVES: The incidence of neural tube defects (NTDs) in Ireland has increased in recent years. This study examines knowledge about folic acid (FA) supplementation for the prevention of NTDs among women presenting for antenatal care. SUBJECTS/METHODS: Women were recruited at their convenience in the first trimester after sonographic confirmation of an ongoing singleton pregnancy. A detailed questionnaire was completed under the supervision of a research dietitian. Clinical and socio-demographic details were collected. RESULTS: Of the 587 women studied, 96% took FA during early pregnancy. Of these, 56.4% cited brain/spinal development or the prevention of brain/spinal defects, spina bifida or NTDs as the reason for taking FA. Multivariate analysis showed that women who were experiencing material deprivation or who were living in Ireland <5 years were least likely to be knowledgeable about the benefits of FA supplementation (P<0.05 for both). Over half (57.1%) of the women did not take FA preconceptionally. The main reason reported for not supplementing preconceptionally was that the woman did not expect to get pregnant (76.4%). Over one-third of women (35%), however, reported that they did not know they needed to take FA before becoming pregnant. CONCLUSIONS: These results highlight the need for a renewed public health campaign in Ireland about the importance of FA. As well as focusing on women who have recently come to live in Ireland, this campaign needs focus on women living in deprivation, as these are the women most at risk of having inadequate knowledge about the importance of FA in improving pregnancy outcomes.

We describe and assess the performance of the gene finding program pretty handy annotation tool (Phat) on sequence from the malaria parasite Plasmodium falciparum. Phat is based on a generalized hidden Markov model (GHMM) similar to the models used in GENSCAN, Genie and HMMgene. In a test set of 44 confirmed gene structures Phat achieves nucleotide-level sensitivity and specificity of greater than 95%, performing as well as the other P. falciparum gene finding programs Hexamer and GlimmerM. Phat is particularly useful for P. falciparum and other eukaryotes for which there are few gene finding programs available as it is distributed with code for retraining it on new organisms. Moreover, the full source code is freely available under the GNU General Public License, allowing for users to further develop and customize it.

We have undertaken the first comparative pilot gene discovery analysis of approximately 25,000 random genomic and expressed sequence tags (ESTs) from three species of Plasmodium, the infectious agent that causes malaria. A total of 5482 genome survey sequences (GSSs) and 5582 ESTs were generated from mung bean nuclease (MBN) and cDNA libraries, respectively, of the ANKA line of the rodent malaria parasite Plasmodium berghei, and 10,874 GSSs generated from MBN libraries of the Salvador I and Belem lines of Plasmodium vivax, the most geographically wide-spread human malaria pathogen. These tags, together with 2438 Plasmodium falciparum sequences present in GenBank, were used to perform first-pass assembly and transcript reconstruction, and non-redundant consensus sequence datasets created. The datasets were compared against public protein databases and more than 1000 putative new Plasmodium proteins identified based on sequence similarity. Homologs of previously characterized Plasmodium genes were also identified, increasing the number of P. vivax and P. berghei sequences in public databases at least 10-fold. Comparative studies with other species of Apicomplexa identified interesting homologs of possible therapeutic or diagnostic value. A gene prediction program, Phat, was used to predict probable open reading frames for proteins in all three datasets. Predicted and non-redundant BLAST-matched proteins were submitted to InterPro, an integrated database of protein domains, signatures and families, for functional classification. Thus a partial predicted proteome was created for each species. This first comparative analysis of Plasmodium protein coding sequences represents a valuable resource for further studies on the biology of this important pathogen.

The use of transposons offers the possibility of a directed approach to DNA sequencing, where a target DNA up to about 6kb in length can be sequenced quickly and with minimal redundancy. Transposons are mobile DNA elements which can be inserted in a reasonably random fashion into the target DNA. An important part of this process is the location of the transposon insertions (known as mapping) and the selection of a sensible subset of transposons to use as priming sites for sequencing reactions. This paper presents a probabilistic method of scoring selected subsets of transposons and a graph-theoretic algorithm for selection of a subset of maximal score.

In this study we explore whether elderly suicide victims who had a previous history of attempted suicide differ from those with no similar history. A group of the elderly, who ended their lives with fatal self-harm (FSH) and had a history of deliberate self-harm (DSH) was compared to a matching group of the elderly who also ended their lives with FSH, but who were not known to have had any history of DSH. The comparison was in respect of epidemiological, social, psychological characteristics, service input and methods of suicide. The elderly, with a history of DSH, were more likely to have been known to the mental health services than the elderly who did not have such a history (P<.05). The two groups used similar methods in their final FSH act. The elderly victims of FSH with or without a previous history of DSH share the same characteristics. The two groups appear to be part of one syndrome. Deliberate self-harm in the elderly should be taken seriously as an unsuccessful suicide rather than a manipulative act or a cry for help and attention.

In this study we examined the association between methods of Deliberate Self Harm (DSH) by the elderly and their subsequent methods of Fatal Self Harm (FSH). Data was collected from the files of inquests into suicide by the elderly in Birmingham and Cheshire Coroner's Courts. All the subjects were above the age of 60, had history of deliberate self harm before the final act of fatal self harm and attracted either suicide or open verdict returned by the Coroners over a period of four years 1995-1998. We compared the methods of Deliberate Self Harm (DSH) to the methods of Fatal Self Harm (FSH) used by all the included elderly. 18 per cent of elderly victims of FSH had a previous history of DSH and in 35 per cent of the sample, the last known attempt of DSH occurred more than one year prior to the FSH. The majority of the methods that had been used in elderly DSH were used again in their final act of FSH. Nearly two thirds of all the elderly who died of an overdose had attempted suicide earlier by an overdose and one in five of those who died by hanging or drowning used the same method in an unsuccessful attempt of FSH within 12 months. A detailed history of DSH can improve the quality of risk assessment of self harm in the elderly. As more than one in three elderly victims of FSH attempted DSH more than a year prior to the final act, it is important when assessing an elderly DSH attempt that we obtain any previous case notes and question informants about the distant as well as the recent past.

We examined the association between the psychiatric history of patients who were the subjects of a coroner's inquest and the recorded verdict, in a seven-year retrospective review. A suicide verdict was less frequently returned on patients who had inpatient psychiatric treatment compared to other unexpected deaths. History and diagnosis of an alcohol-related condition, method of death and intimation of intent were the main factors that appeared to be associated with the coroner's verdict. Age, sex, duration of illness, time and number of admissions, previous suicide attempts and treatment received did not appear to be significantly associated with the recorded verdict.

Concern about mentally ill patients admitted to psychiatric hospitals for short periods is long standing. Often, admission takes place at night when clinical expertise is in short supply. In this study, the researchers found that these patients were admitted to expensive hospital beds not for health needs but often for social reasons. The authors suggest that community-based, short stay psychiatric units are more suitable for the care of these patients.

A consecutive series of 320 patients with an intracapsular fracture of the hip treated with a dynamic locking plate (Targon Femoral Neck (TFN)) were reviewed. All surviving patients were followed for a minimum of two years. During the follow-up period 109 patients died. There were 112 undisplaced fractures, of which three (2.7%) developed nonunion or re-displacement and five (4.5%) developed avascular necrosis of the femoral head. Revision to an arthroplasty was required for five patients (4.5%). A further six patients (5.4%) had elective removal of the plate and screws. There were 208 displaced fractures, of which 32 (15.4%) developed nonunion or re-displacement and 23 (11.1%) developed avascular necrosis. A further four patients (1.9%) developed a secondary fracture around the TFN. Revision to a hip replacement was required for 43 patients (20.7%) patients and a further seven (3.3%) had elective removal of the plate and screws. It is suggested that the stronger distal fixation combined with rotational stability may lead to a reduced incidence of complications related to the healing of the fracture when compared with other contemporary fixation devices but this needs to be confirmed in further studies.
