Olive Oil, Sunflower Oil or no Oil for Baby Dry Skin or Massage: A Pilot, Assessor-blinded, Randomized Controlled Trial (the Oil in Baby SkincaRE [OBSeRvE] Study).

Topical oils on baby skin may contribute to development of childhood atopic eczema. A pilot, assessor-blinded, randomized controlled trial assessed feasibility of a definitive trial investigating their impact in neonates. One-hundred and fifteen healthy, full-term neonates were randomly assigned to olive oil, sunflower oil or no oil, twice daily for 4 weeks, stratified by family history of atopic eczema. We measured spectral profile of lipid lamellae, trans-epidermal water loss (TEWL), stratum corneum hydration and pH and recorded clinical observations, at baseline, and 4 weeks post-birth. Recruitment was challenging (recruitment 11.1%; retention 80%), protocol adherence reasonable (79-100%). Both oil groups had significantly improved hydration but significantly less improvement in lipid lamellae structure compared to the no oil group. There were no significant differences in TEWL, pH or erythema/skin scores. The study was not powered for clinical significance, but until further research is conducted, caution should be exercised when recommending oils for neonatal skin.

The effectiveness of acupressure for the control and management of chemotherapy-related acute and delayed nausea: a randomized controlled trial.

CONTEXT: Both positive and negative results have been reported in the literature from the use of acupressure at the P6 point, providing evidence of highly suggestive but not conclusive results. OBJECTIVES: To clarify whether acupressure is effective in the management of chemotherapy-related nausea and vomiting. METHODS: A randomized, three-group, sham-controlled trial was designed. Patients with cancer receiving chemotherapy were randomized to receive standardized antiemetics and acupressure wristbands, sham acupressure wristbands, or antiemetics alone. Primary outcome assessment (nausea) was carried out daily for seven days per chemotherapy cycle over four cycles. Secondary outcomes included vomiting, psychological distress, and quality of life. RESULTS: Five hundred patients were randomized. Primary outcome analysis (nausea in Cycle 1) revealed no statistically significant differences between the three groups, although nausea levels in the proportion of patients using wristbands (both real and sham) were somewhat lower than those in the proportion of patients using antiemetics-only group. Adjusting for gender, age, and emetic risk of chemotherapy, the odds ratio of lower nausea experience was 1.18 and 1.42 for the acupressure and sham acupressure groups, respectively. A gender interaction effect was evident (P = 0.002). No significant differences were detected in relation to vomiting, anxiety, and quality-of-life measures. CONCLUSION: No clear recommendations can be made about the use of acupressure wristbands in the management of chemotherapy-related nausea and vomiting as results did not reach statistical significance. However, the study provided evidence of encouraging signals in relation to improved nausea experience and warrants further consideration in both practice and further clinical trials. TRIAL REGISTRATION: This trial is registered with the ISRCT register, number ISRCTN87604299.

A pilot quasi-experimental study to determine the feasibility of implementing a partograph e-learning tool for student midwife training in Nairobi.

OBJECTIVE: the partograph is a tool used globally to record labour progress. Although it has the potential to improve maternal and neonatal outcomes, some midwives struggle with using it in practice. Training in partograph use is limited, and the theory is often divorced from practice. Innovative ways of improving training are urgently required. We therefore aimed to determine whether the use of an e-learning tool is beneficial for learning partograph skills. DESIGN: an uncontrolled before-and-after study was conducted, informed by Kirkpatrick's four-stage model of evaluation; we report on the first two stages. We included a cohort of third and fourth year midwifery students who were studying at one university in Nairobi. The same hypothetical case scenario was used, pre- and post-implementation of the World Health Organization partograph e-learning tool, to assess students' partograph completion ability. Views on the tool were also sought, using semi-structured questionnaires. Data were analysed using standard statistical techniques and framework analysis. FINDINGS: 92 (88%) students participated. Students expressed positive views about the e-learning tool. However, the mean post-intervention score (27.21) was less than half of the maximum obtainable score. There was some improvement in test scores; year three mean score pre-intervention was 21.39 (SD 5.72), which increased to 25.10 (5.41) post-intervention (paired-t=3.47, p=0.001); year four mean score pre-intervention was 24.39 (5.98) which increased to 29.30 (6.77) post-intervention (paired t=3.85, df=91, p<0.001). In the post-test, year four students scored higher than year three students (unpaired t=3.28, df=90, p=0.001). Students were unable to plot cervical dilatation correctly, once established labour had been confirmed. KEY CONCLUSION: e-Learning training is acceptable to student midwives and has the potential to be an effective means of teaching the practical application of the partograph. However, in this study, their inability to correctly plot transference from the latent to active phase of labour suggests that the partograph itself may be too complicated. Modifications and further evaluation of the e-learning tool would be required before any widespread implementation. Furthermore, students need the clinical support to operationalise their learning; educating qualified midwives and obstetricians to be positive role models when completing the partograph would be one potential solution. Further research is required, taking on board the recommendations from our pilot study, to investigate the impact of partograph e-learning on practice and clinical outcomes.

Place of birth or place of death: an evaluation of 1139 maternal deaths in Nigeria.

OBJECTIVE: to describe the incidence of maternal death by age, marital status, timing and place of death in Ibadan North and Ido Local Government Areas of Oyo State, Nigeria. DESIGN: a retrospective study using multistage sampling with stratification and clustering to select local government areas, political wards and households. We included one eligible subject by household in the sample. Data on maternal mortality were collected using the principles of the indirect sisterhood method. SETTING: Ibadan city of Oyo state, Nigeria. We included eight randomly selected political wards from Ibadan North LGA (urban) and Ido LGA (rural). PARTICIPANTS: 3028 participants were interviewed using the four questions of the indirect sisterhood method: How many sisters have you ever had who are ever married (or who survived until age 15)? How many are dead? How many are alive? How many died while they were pregnant, during childbirth, or within six weeks after childbirth (that is, died of maternal causes)? We also included other questions such as place and timing of death, age of women at death and number of pregnancies. FINDINGS: 1139 deaths were reported to be related to pregnancy, childbirth or the puerperium. Almost half were aged between aged 25-34 years. More deaths occurred to women who were pregnant for the first time (33.4%, n=380) than for any other number of pregnancies, with 49.9% (n=521) dying within 24 hours after childbirth or abortion and 30.9% (n=322) dying after 24 hours but within 72 hours after childbirth or abortion. Only 71.5% (n=809) were reported to have been admitted to health-care facilities before their death, the percentage being higher in the urban LGA (72.4%, n=720) than the rural LGA (65.4%, n=89). The percentage being admitted varied from one political ward to another (from 42.9% to 80.4%), the difference being statistically significant (χ(2)=17.55, df=7, p=0.014). The majority of the deaths occurred after childbirth (63.5%, n=723). Most deaths were said to have occurred in the hospital (38.6%) or private clinic (28.2%), with 16.0% dying at home and 6.5% on the way to hospital. KEY CONCLUSIONS: maternal mortality in Nigeria is still unacceptably high. IMPLICATIONS FOR PRACTICE: ensure adequate training, recruitment and deployment of midwives and others with midwifery skills. Ensure midwives and other skilled birth attendants are backed up with functioning and well equipped health-care facilities. Provide health education and information to the public with regard to reproductive health and ensure the development and dissemination of a policy regarding attendance at birth by only health workers who have midwifery skills.

Mutation altering the miR-184 seed region causes familial keratoconus with cataract.

MicroRNAs (miRNAs) bind to complementary sequences within the 3' untranslated region (UTR) of mRNAs from hundreds of target genes, leading either to mRNA degradation or suppression of translation. We found that a mutation in the seed region of miR-184 (MIR184) is responsible for familial severe keratoconus combined with early-onset anterior polar cataract by deep sequencing of a linkage region known to contain the mutation. The mutant form fails to compete with miR-205 (MIR205) for overlapping target sites on the 3' UTRs of INPPL1 and ITGB4. Although these target genes and miR-205 are expressed widely, the phenotype is restricted to the cornea and lens because of the very high expression of miR-184 in these tissues. Our finding highlights the tissue specificity of a gene network regulated by a miRNA. Awareness of the important function of miRNAs could aid identification of susceptibility genes and new therapeutic targets for treatment of both rare and common diseases.

The Hyperemesis Impact of Symptoms Questionnaire: development and validation of a clinical tool.

BACKGROUND: The Hyperemesis Impact of Symptoms Questionnaire is a clinical tool designed to assess holistically the impact of the physical and psychosocial symptoms of hyperemesis gravidarum (HG) on individuals. Its purpose is to aid planning and implementation of tailored care for women with HG. To our knowledge no similar tool exists. OBJECTIVE: To assess the validity and reliability of the HIS questionnaire. DESIGN: As no similar tool exists, we compared the HIS with three tools that reflect its key areas: physical impact (Pregnancy Unique Quantification of Emesis--PUQE score and markers of severity of HG), psychological impact (Hospital Anxiety and Depression Score--HADS) and social impact (SF12 quality of life score). SETTING: A large regional referral, women and children's hospital in the North West of England. PARTICIPANTS: The HIS was evaluated on 50 women admitted to hospital with HG and 50 women recruited from ante-natal clinic without severe nausea and vomiting of pregnancy and with an uncomplicated pregnancy. RESULTS: Good criterion validity was demonstrated by strong significant correlations with all three scores (PUQE, r=0.75, p<0.001, HADS, depression r=0.76, p<0.001, and SF12, mental component r=-0.65, p<0.001). The HIS showed good internal consistency, Cronbach alpha 0.87, split half 0.80. CONCLUSIONS: There is evidence for the validity and reliability of the HIS to assess the impact of the physical and psychosocial symptoms of HG. Further research is currently underway to establish the clinical utility of the HIS questionnaire in the care of women hospitalised with HG.

Internal mammary artery smooth muscle cells resist migration and possess high antioxidant capacity.

OBJECTIVE: This study investigated whether differences exist in atherogen-induced migratory behaviors and basal antioxidant enzyme capacity of vascular smooth muscle cells (VSMC) from human coronary (CA) and internal mammary (IMA) arteries. METHODS: Migration experiments were performed using the Dunn chemotaxis chamber. The prooxidant [NAD(P)H oxidase] and antioxidant [NOS, superoxide dismutase, catalase and glutathione peroxidase] enzyme activities were determined by specific assays. RESULTS: Chemotaxis experiments revealed that while both sets of VSMC migrated towards platelet-derived growth factor-BB (1-50 ng/ml) and angiotensin II (1-50 nM), neither oxidized-LDL (ox-LDL, 25-100 microg/ml) nor native LDL (100 microg/ml) affected chemotaxis in IMA VSMC. However, high dose ox-LDL produced significant chemotaxis in CA VSMC that was inhibited by pravastatin (100 nM), mevastatin (10 nM), losartan (10 nM), enalapril (1 microM), and MnTBAP (a free radical scavenger, 50 microM). Microinjection experiments with isoprenoids i.e. geranylgeranylpyrophosphate (GGPP) and farnesylpyrophosphate (FPP) showed distinct involvement of small GTPases in atherogen-induced VSMC migration. Significant increases in antioxidant enzyme activities and nitrite production along with marked decreases in NAD(P)H oxidase activity and O2- levels were determined in IMA versus CA VSMC. CONCLUSIONS: Enhanced intrinsic antioxidant capacity may confer on IMA VSMC resistance to migration against atherogenic agents. Drugs that regulate ox-LDL or angiotensin II levels also exert antimigratory effects.

Characterisation of Pt MYB1, an R2R3-MYB from pine xylem.

A cDNA encoding a member of the R2R3-MYB family of transcription factors was cloned from a library constructed from differentiating Pinus taeda (loblolly pine) xylem RNA. This MYB family member, Pinus taeda MYB1 (PtMYB1), was most abundantly expressed in differentiating xylem, as assessed by both ribonuclease protection assays, and by northern blot analysis with poly(A)-enriched RNA. Similar to other plant R2R3-MYB family members, recombinant Pt MYB1 protein was able to bind to AC elements in electrophoretic mobility shift assays (EMSAs). AC elements are DNA motifs rich in adenosine and cytosine that have been implicated in the xylem-localised regulation of genes encoding lignin biosynthetic enzymes. Pt MYB1 not only bound to AC elements, but was also able to induce AC-element-dependent shifts in the electrophoretic mobility of a plant promoter that contains three AC elements, the minimal PHENYLALANINE AMMONIA-LYASE 2 (PAL2) promoter from Phaseolus vulgaris. Transcriptional activation assays conducted using yeast showed that Pt MYB1 also activated transcription, and that it did so in an AC-element-dependent fashion. Pt MYB1 also activated transcription from the minimal PAL2 promoter in plant cells in an AC-element-dependent fashion, as revealed by transient transcriptional activation assays with microprojectile-bombarded tobacco NT-1 cells. Taken together, these finding are consistent with the hypothesis that Pt MYB1 may regulate transcription from cis -acting AC elements in pine xylem.
