ABSTRACT

BACKGROUND: This study explores live and recorded music listening in the outpatient pain clinic. There is evidence demonstrating the effectiveness of live and recorded music in a hospital setting but a comparison study of this kind has yet to be conducted. METHODS: A multimethod survey study design was used. A questionnaire utilizing rating scales was self-administered across two outpatient pain clinic waiting rooms. Patients were included through convenience sampling. In one clinic, a playlist of recorded music curated by two of the authors was provided. In the second clinic, a music therapy student played live music using guitar, flute, and voice. The questionnaire gathered data on music's impact on pain and emotional states, as well as attitudes toward music in the waiting room. Quantitative data was analyzed using descriptive statistics and qualitative data, gathered in the questionnaires open ended question, was analyzed using thematic analysis. RESULTS: The questionnaire was completed by 200 adult patients. Patients reported lowered levels of anxiety, stress, and pain in both clinics, as well as a shorter waiting time and more caring experience. Patients in the live music clinic reported that music lowered levels of stress, nervousness, agitation, and pain more than in the recorded music clinic. CONCLUSIONS: Participants in this study identified that music is a useful tool in the pain clinic waiting room. This study contributes to evidence that music should be considered as a complimentary treatment for people living with pain and in the wider hospital setting. Additional research is warranted with a control group, pre- and posttesting, and studies of music in hospitals in a range of cultural contexts.

ABSTRACT

OBJECTIVE: To investigate the association between planned mode of birth after previous caesarean section and a child's risk of having a record of special educational needs (SENs). DESIGN: Population-based cohort study. SETTING: Scotland. POPULATION: A cohort of 44 892 singleton children born at term in Scotland between 2002 and 2011 to women with one or more previous caesarean sections. METHODS: Linkage of Scottish national health and education data sets. MAIN OUTCOME MEASURES: Any SENs and specific types of SEN recorded when a child was aged 4-11 years and attending a Scottish primary or special school. RESULTS: Children born following planned vaginal birth after previous caesarean (VBAC) compared with elective repeat caesarean section (ERCS) had a similar risk of having a record of any SENs (19.24 versus 17.63%, adjusted risk ratio aRR 1.04, 95% CI 0.99-1.09) or specific types of SEN. There was also little evidence that planned VBAC with or without labour induction compared with ERCS was associated with a child's risk of having a record of any SENs (21.42 versus 17.63%, aRR 1.09, 95% CI 1.01-1.17 and 18.78 versus 17.63%, aRR 1.03, 95% CI 0.98-1.08, respectively) or most types of SEN. However, an increased risk of sensory impairment was seen for planned VBAC with labour induction compared with ERCS (1.18 versus 0.78%, risk difference 0.4%, adjusted odds ratio aOR 1.60, 95% CI 1.09-2.34). CONCLUSIONS: This study provides little evidence of an association between planned mode of birth after previous caesarean and SENs in childhood beyond a small absolute increased risk of sensory impairment seen for planned VBAC with labour induction. This finding may be the result of performing multiple comparisons or residual confounding. The findings provide valuable information to manage and counsel women with previous caesarean section concerning their future birth choices. TWEETABLE ABSTRACT: There is little evidence planned mode of birth after previous caesarean section is associated with special educational needs in childhood.

ABSTRACT

To understand and reduce the impact of postoperative complications, we studied 568 patients who had had operations over 72 months in our hospital. Multivariate analysis indicated that factors indicative of coexisting conditions (including activated systemic inflammation) and the complexity of the operation are primary determinants of postoperative complications. The enhanced recovery after surgery (ERAS) care pathway did not have an effect on their occurrence or severity. Systematic study of patients' toleration of major head and neck operations is required, as optimal perioperative care pathways remain elusive.

ABSTRACT

OBJECTIVES: To describe the characteristics, management and outcomes of women giving birth at advanced maternal age (≥48 years). DESIGN: Population-based cohort study using the UK Obstetric Surveillance System (UKOSS). SETTING: All UK hospitals with obstetrician-led maternity units. POPULATION: Women delivering at advanced maternal age (≥48 years) in the UK between July 2013 and June 2014 (n = 233) and 454 comparison women. METHODS: Cohort and comparison group identification through the UKOSS monthly mailing. MAIN OUTCOME MEASURES: Pregnancy complications. RESULTS: Older women were more likely than comparison women to be overweight (33% versus 23%, P = 0.0011) or obese (23% versus 19%, P = 0.0318), nulliparous (53% versus 44%, P = 0.0299), have pre-existing medical conditions (44% versus 28%, P < 0.0001), a multiple pregnancy (18% versus 2%, P < 0.0001), and conceived following assisted conception (78% versus 4%, P < 0.0001). Older women appeared more likely than comparison women to have pregnancy complications including gestational hypertensive disorders, gestational diabetes, postpartum haemorrhage, caesarean delivery, iatrogenic and spontaneous preterm delivery on univariable analysis and after adjustment for demographic and medical factors. However, adjustment for multiple pregnancy or use of assisted conception attenuated most effects, with significant associations remaining only with gestational diabetes (adjusted odds ratio [aOR] 4.81, 95% CI 1.93-12.00), caesarean delivery (aOR 2.78, 95% CI 1.44-5.37) and admission to an intensive care unit (aOR 33.53, 95% CI 2.73-412.24). CONCLUSIONS: Women giving birth at advanced maternal age have higher risks of a range of pregnancy complications. Many of the increased risks appear to be explained by multiple pregnancy or use of assisted conception. TWEETABLE ABSTRACT: The pregnancy complications in women giving birth aged 48 or over are mostly explained by multiple pregnancy.

ABSTRACT

INTRODUCTION: Axillary status remains an important prognostic indicator in breast cancer. Certain patients with a positive sentinel node (SLNB) may not benefit from axillary clearance (AC). Uncertainty remains if this approach could be applied to patients diagnosed with axillary metastases on ultrasound-guided fine needle aspiration cytology (USFNAC). The aim of this study was to compare nodal burden in patients with positive USFNAC and a positive SLNB. METHODS: A retrospective study was performed involving all BC patients between 2007 and 2014 who had either pre-operative USFNAC or a SLNB. Patient/tumour characteristics and nodal burden were examined in all patients proceeding to AC. RESULTS: 974 patients were eligible for analysis. 439 patients (45 %) had positive USFNAC and 535 (55 %) had a positive SLNB. USFNAC-positive patients were more likely to undergo mastectomy (Chi-square test; p < 0.001), have extra-nodal extension (p < 0.001), be oestrogen receptor negative (p < 0.001) and be HER2 positive (p < 0.001). The median total number of lymph nodes (LNs) excised during AC was higher in the USFNAC group (Mann-Whitney test; 23 vs. 21; p < 0.001). The median total number of involved LNs was 3 (range 1-47) in FNAC-positive patients versus 1 (range 1-37) in SLNB-positive patients (p < 0.001). The median number of involved LNs in level 1 was 3 in FNAC-positive patients versus 1 in SLNB-positive patients (p < 0.001). Within the SLN-positive group, 49 % of the patients had only one involved LN, 28 % had two nodes involved and 23 % had ≥3. In comparison, within the FNAC-positive group only 13 % of the patients had one involved LN, 12 % had two nodes involved and 74 % had ≥3. CONCLUSION: Patients with positive USFNAC have more aggressive clinico-pathological characteristics and higher nodal burden compared to SLNB-positive patients. Currently, the authors advocate that patients not receiving neoadjuvant chemotherapy, with a positive USFNAC, should proceed directly to an axillary ALND.

ABSTRACT

OBJECTIVE: To describe the incidence, risk factors, management and outcomes of amniotic-fluid embolism (AFE) over time. DESIGN: A population-based cohort and nested case-control study using the UK Obstetric Surveillance System (UKOSS). SETTING: All UK hospitals with obstetrician-led maternity units. POPULATION: All women diagnosed with AFE in the UK between February 2005 and January 2014 (n = 120) and 3839 control women. METHODS: Prospective case and control identification through UKOSS monthly mailing. MAIN OUTCOME MEASURES: Amniotic-fluid embolism, maternal death or permanent neurological injury. RESULTS: The total and fatal incidence of AFE, estimated as 1.7 and 0.3 per 100 000, respectively, showed no significant temporal trend over the study period and there was no notable temporal change in risk factors for AFE. Twenty-three women died (case fatality 19%) and seven (7%) of the surviving women had permanent neurological injury. Women who died or had permanent neurological injury were more likely to present with cardiac arrest (83% versus 33%, P < 0.001), be from ethnic-minority groups (adjusted odds ratio [OR] 2.85, 95% confidence interval [95% CI] 1.02-8.00), have had a hysterectomy (unadjusted OR 2.49, 95% CI 1.02-6.06), had a shorter time interval between the AFE event and when the hysterectomy was performed (median interval 77 minutes versus 248 minutes, P = 0.0315), and were less likely to receive cryoprecipitate (unadjusted OR 0.30, 95% CI 0.11-0.80). CONCLUSION: There is no evidence of a temporal change in the incidence of or risk factors for AFE. Further investigation is needed to establish whether earlier treatments can reverse the cascade of deterioration leading to severe outcomes.

ABSTRACT

OBJECTIVE: To describe the management and outcomes of placenta accreta, increta, and percreta in the UK. DESIGN: A population-based descriptive study using the UK Obstetric Surveillance System (UKOSS). SETTING: All 221 UK hospitals with obstetrician-led maternity units. POPULATION: All women diagnosed with placenta accreta, increta, and percreta in the UK between May 2010 and April 2011. METHODS: Prospective case identification through the monthly mailing of UKOSS. MAIN OUTCOME MEASURES: Median estimated blood loss, transfusion requirements. RESULTS: A cohort of 134 women were identified with placenta accreta, increta, or percreta: 50% (66/133) were suspected to have this condition antenatally. In women with a final diagnosis of placenta increta or percreta, antenatal diagnosis was associated with reduced levels of haemorrhage (median estimated blood loss 2750 versus 6100 ml, P = 0.008) and a reduced need for blood transfusion (59 versus 94%, P = 0.014), possibly because antenatally diagnosed women were more likely to have preventative therapies for haemorrhage (74 versus 52%, P = 0.007), and were less likely to have an attempt made to remove their placenta (59 versus 93%, P < 0.001). Making no attempt to remove any of the placenta, in an attempt to conserve the uterus or prior to hysterectomy, was associated with reduced levels of haemorrhage (median estimated blood loss 1750 versus 3700 ml, P = 0.001) and a reduced need for blood transfusion (57 versus 86%, P < 0.001). CONCLUSIONS: Women with placenta accreta, increta, or percreta who have no attempt to remove any of their placenta, with the aim of conserving their uterus, or prior to hysterectomy, have reduced levels of haemorrhage and a reduced need for blood transfusion, supporting the recommendation of this practice.

ABSTRACT

In 2010, Coxiella burnetii was identified at a high prevalence in the placentas of Northern fur seals (Callorhinus ursinus) collected at a single rookery on St. Paul Island Alaska; an area of the United States where the agent was not known to be present. As contamination was hypothesized as a potential cause of false positives, but nothing was known about environmental C. burnetii in the region, an environmental survey was conducted to look for the prevalence and distribution of the organism on the island. While environmental prevalence was low, two strains of the organism were identified using PCR targeting the COM1 and IS1111 genes. The two strains are consistent with the organism that has been increasingly identified in marine mammals as well as a strain type more commonly found in terrestrial environments and associated with disease in humans and terrestrial animals. Further work is needed to elucidate information regarding the ecology of this organism in this region, particularly in association with the coastal environment.

ABSTRACT

BACKGROUND AND PURPOSE: The severity of white matter hyperintensity, or leukoaraiosis, is a marker of cerebrovascular disease. In stroke, WMH burden is strongly linked to lacunar infarction; however, impaired cerebral perfusion due to extracranial or intracranial atherosclerosis may also contribute to WMH burden. We sought to determine whether WMH burden is associated with extracranial or intracranial stenosis in patients with AIS. MATERIALS AND METHODS: Patients with AIS with admission head/neck CTA and brain MR imaging were included in this analysis. "Extracranial stenosis" was defined as >50% stenosis in the extracranial ICA, and "intracranial," as >50% stenosis in either the middle, anterior, or posterior cerebral arteries on CTA, on either side. WMHV was determined by using a validated semiautomated protocol. Multiple regression was used to assess the relationship between WMHV and extracranial/intracranial atherosclerosis. RESULTS: Of 201 subjects, 51 (25.4%) had extracranial and 63 (31.5%) had intracranial stenosis. Mean age was 62 ± 15 years; 36% were women. Mean WMHV was 12.87 cm(3) in the extracranial and 8.59 cm(3) in the intracranial stenosis groups. In univariate analysis, age (P < .0001), SBP and DBP (P = .004), and HTN (P = .0003) were associated with WMHV. Extracranial stenosis was associated with greater WMHV after adjustment for intracranial stenosis (P = .04). In multivariate analysis including extracranial stenosis, only age (P < .0001) and HTN (P = .03) demonstrated independent effects on WMHV. CONCLUSIONS: In our cohort of patients with AIS, age and HTN were the strongest determinants of the WMHV severity. Future studies are warranted to unravel further association between WMHV and cerebral vessel atherosclerosis.

ABSTRACT

OBJECTIVE: White matter hyperintensity (WMH) may be a marker of an underlying cerebral microangiopathy. Therefore, we hypothesized that WMH would be most severe in patients with lacunar stroke and intracerebral hemorrhage (ICH), 2 types of stroke in which cerebral small vessel (SV) changes are pathophysiologically relevant. METHODS: We determined WMH volume (WMHV) in cohorts of prospectively ascertained patients with acute ischemic stroke (AIS) (Massachusetts General Hospital [MGH], n = 628, and the Ischemic Stroke Genetics Study [ISGS], n = 263) and ICH (MGH, n = 122). RESULTS: Median WMHV was 7.5 cm³ (interquartile range 3.4-14.7 cm³) in the MGH AIS cohort (mean age 65 ± 15 years). MGH patients with larger WMHV were more likely to have lacunar stroke compared with cardioembolic (odds ratio [OR] = 1.87 per SD normally transformed WMHV), large artery (OR = 2.25), undetermined (OR = 1.87), or other (OR = 1.85) stroke subtypes (p < 0.03). These associations were replicated in the ISGS cohort (p = 0.03). In a separate analysis, greater WMHV was seen in ICH compared with lacunar stroke (OR = 1.2, p < 0.02) and in ICH compared with all ischemic stroke subtypes combined (OR = 1.34, p < 0.007). CONCLUSIONS: Greater WMH burden was associated with SV stroke compared with other ischemic stroke subtypes and, even more strongly, with ICH. These data, from 2 independent samples, support the model that increasing WMHV is a marker of more severe cerebral SV disease and provide further evidence for links between the biology of WMH and SV stroke.

ABSTRACT

Current guidance recommends that all adults should take a minimum of 10,000 steps a day to remain healthy. We assessed the activity levels of 45 anaesthetists while at work, using accelerometers. These devices also allowed us to measure sitting, standing and walking time--features of the working day that are also likely to contribute to health and well-being. In addition, each anaesthetist was asked to guess how many steps they had taken and complete a questionnaire assessing current activity levels. Median (IQR [range]) number of steps taken per day at work was 3694 (2435-4646 [1444-7712]). Almost all anaesthetists underestimated the number of steps they had taken. We concluded that no anaesthetists in our study were able to take the recommended 10,000 steps solely during their working day. A concerted effort is required in recreational time to ensure anaesthetists stay fit and healthy.

ABSTRACT

The pharmacokinetics and metabolism of reparixin (formerly repertaxin), a potent and specific inhibitor of the chemokine CXCL8, were investigated in rats and dogs after intravenous administration of [14C]-reparixin L-lysine salt. Protein binding of reparixin was investigated in vitro in rat, dog, rabbit, cynomolgus monkey and human plasma. Plasma protein binding of reparixin was >99% in the laboratory animals and humans up to 50 microg ml-1, but lower at higher concentrations. Although radioactivity was rapidly distributed into rat tissues, Vss was low (about 0.15 l kg-1) in both rat and dog. Nevertheless, reparixin was more rapidly eliminated in rats (t1/2 approximately 0.5 h) than in dogs (t1/2 approximately 10 h). Systemic exposure in dog was due primarily to parent drug, but metabolites played a more prominent role in rat. Oxidation of the isobutyl side-chain was the major metabolic pathway in rat, whereas hydrolysis of the amide bond predominated in dog. Urinary excretion, which accounted for 80-82% of the radioactive dose, was the major route of elimination in both species, and biotransformation of reparixin was complete before excretion.

ABSTRACT

The triazine herbicide, atrazine, has come under scrutiny for its reported feminizing effects in amphibians. To date, there is little information concerning the effects of atrazine on reproduction in avian species. The current study examined the putative reproductive toxicity of atrazine after exposure in ovo. Atrazine at 504, 246, and 123 microg/kg was administered to Japanese quail eggs before incubation. The eggs were hatched and the birds raised to 14 days of age. Indices of hatchability, sex ratios, and growth were determined. Furthermore, circulating concentrations of reproductive hormones (estradiol, progesterone, and testosterone) and gonadal histology were examined. Atrazine at 504 microg/kg decreased 14-day hatchling weight by 13.1% versus controls. However, no detrimental effects on hatchability or sex ratios were observed. In female birds, atrazine at 504 microg/kg decreased ovarian weights and circulating concentrations of progesterone to 48.3% and 73.3%, respectively, versus control. However, concentrations of estradiol and testosterone did not differ from controls. In male quail, at all doses tested, atrazine had no effect on gonadal weights or circulating concentrations of estradiol, testosterone, or progesterone. Moreover, no incidences of left ovotestis formation were observed. In contrast, 10 ng/kg ethinylestradiol (a positive control) induced the formation of a left ovotestis in four of eight birds analyzed. The current results may suggest that exposure to atrazine in ovo at concentrations above ecologic relevance exerts effects on the reproductive system of young Japanese quail. However, no evidence is presented that atrazine induces feminization of the testis in male quail.

ABSTRACT

In this review, we combine the results of our published and unpublished work with the published results of other laboratories to provide an updated map of the centromeric heterochromatin of chromosome 3 in Drosophila melanogaster. To date, we can identify more than 20 genes (defined DNA sequences with well-characterized functions and (or) defined genetic complementation groups), including at least 16 essential loci. With the ongoing emergence of data from genetic, cytological, and genome sequencing studies, we anticipate continued, substantial progress towards understanding the function, structure, and evolution of centric heterochromatin.

ABSTRACT

BACKGROUND: The clinical presentation of celiac disease--a life-long gluten intolerance--may be characterized by chronic abdominal pain. The objective of this study was to determine if children with recurrent abdominal pain had a higher prevalence of antiendomysial antibodies (a serologic marker of celiac disease) compared with healthy children. METHODS: Children with recurrent abdominal pain and healthy control participants were recruited from the offices of community pediatricians. Serum samples were drawn and antiendomysial antibodies were measured in both groups. Demographic data included age, gender, height, and weight. RESULTS: A total of 200 children were recruited, of whom 173 (87%) had serum samples drawn. Of these, 92 were children with recurrent abdominal pain and 81 were control participants. Only 2 of the 173 samples (1.2%) were positive for antiendomysial antibody. The frequency of antiendomysial antibody positivity in children with recurrent abdominal pain was 1 in 92 (1%; 95% confidence interval, 0-6%) compared with 1 in 81 (1%; 95% confidence interval, 0-7%) in control participants. CONCLUSIONS: This community-based case-control study found no association between recurrent abdominal pain and the prevalence of antiendomysial antibody. Therefore, these data do not support screening for celiac disease in the child with classic recurrent abdominal pain in the primary care setting.

ABSTRACT

Previous research finds a significant relationship between socioeconomic inequalities and health status: individuals with lower income, education, and occupational prestige have and report more health problems. Interestingly, this relationship is not consistent across the life cycle: health differences among adolescents across socioeconomic groups are not as clearly defined. Using data (n = 1,039) on adolescents from southern Hungary, we examine the role of socioeconomic differences in predicting psychosocial health. We argue that this investigation is of particular importance in a post-communist system where the general perception of SES is undergoing significant transformation. Findings show that classical' SES (socioeconomic status) indicators (manual/nonmanual occupational status) were not significant predictors of psychosocial health in this sample of Hungarian adolescents. While parents' employment status as a 'objective' SES indicator had limited effect, SES self-assessment, as a subjective SES variable, proved to be a strong predictor of adolescents' psychosocial health. We discuss the implications of these findings for the broader SES-health literature with specific attention paid to the impact these relationships may have for adolescent and young adult development in a post-communist country like Hungary.

ABSTRACT

We have further characterized essential loci within the centric heterochromatin of the left arm of chromosome 3 (3L) of Drosophila melanogaster, using EMS, radiation and P element mutagenesis. We failed to find any new essential genes, a result that suggests a lower-than-average gene density in this region. Mutations affecting expression of the most proximal gene [lethal 1, l1 or l(3)80Fj] act as dominant suppressors of Polycomb (Pc), behavior which is consistent with a putative trithorax group (trx-G) gene. The third gene to the left of the centromere [lethal 3, l3 or l(3)80Fh] is likely to correspond to verthandi (vtd), a known trx-G gene that plays a role in the regulation of hedgehog (hh) expression and signalling. The intervening gene [lethal 2, l2 or l(3)80Fi] is required throughout development, and mutant alleles have interesting phenotypes; in various allelic combinations that survive, we observe fertility, bristle, wing, eye and cuticle defects.

ABSTRACT

BACKGROUND: Serotonin 5-HT(4) receptors are located on enteric cholinergic neurones and may regulate peristalsis. 5-HT(4) receptors on primary afferent neurones have been postulated to modulate visceral sensation. While 5-HT(4) agonists are used as prokinetic agents, the physiological role of 5-HT(4) receptors in the human gut is unknown. AIMS: Our aim was to characterise the role of 5-HT(4) receptors in regulating gastrointestinal motor and sensory function in healthy subjects under baseline and stimulated conditions with a 5-HT(4) receptor antagonist. METHODS: Part A compared the effects of placebo to four doses of a 5-HT(4) receptor antagonist (SB-207266) on the cisapride mediated increase in plasma aldosterone (a 5-HT(4) mediated response) and orocaecal transit in 18 subjects. In part B, 52 healthy subjects received placebo, or 0.05, 0.5, or 5 mg of SB-207266 for 10-12 days; gastric, small bowel, and colonic transit were measured by scintigraphy on days 7-9, and fasting and postprandial colonic motor function, compliance, and sensation during distensions were assessed on day 12. RESULTS: Part A: 0.5, 5, and 20 mg doses of SB-207266 had significant and quantitatively similar effects, antagonising the cisapride mediated increase in plasma aldosterone and acceleration of orocaecal transit. Part B: SB-207266 tended to delay colonic transit (geometric centre of isotope at 24 (p=0.06) and 48 hours (p=0.08)), but did not have dose related effects on transit, fasting or postprandial colonic motor activity, compliance, or sensation. CONCLUSION: 5-HT(4) receptors are involved in the regulation of cisapride stimulated orocaecal transit; SB 207266 tends to modulate colonic transit but not sensory functions or compliance in healthy human subjects.
