Background: Medication use during pregnancy and lactation can be unavoidable, but knowledge on safety for the fetus or breastfed infant is limited among patients and healthcare providers. Research aim: This study aimed to determine (a) the prevalence of medication use in pregnant and lactating women in a tertiary academic center, (b) the types and safety of these medicines, and (c) the influence of medication use on initiation of breastfeeding. Methods: This study used a cross-sectional survey among women ( N = 292) who underwent high-risk or low-risk deliveries. Data about their use of prescribed, over-the-counter, and homeopathic medication during pregnancy were obtained through a structured interview, followed by a questionnaire during lactation. Safety was classified according to the risk classification system from the Dutch Teratological Information Service. Results: Overall, 95.5% of participants used medication. One third of participants used at least one medicine with an unknown risk for the fetus. Teratogenic medication was used by 6.5% of participants, whereas 29.5% used medication with a (suspected) pharmacological effect on the fetus. Lactation was initiated by 258 (88.7%) participants, of which 84.2% used medication while breastfeeding. In 3.8% of participants, this medication was classified unsafe, but none used medication with an unknown risk. One-third of the nonlactating participants decided not to initiate breastfeeding because of medication use. In 70% of participants, this decision was appropriate. Conclusion: The prevalence of overall use of medication in Dutch pregnant and lactating women admitted to a tertiary center was high. There is an urgent need for pharmacometric studies for determination of the safe use of the most frequently used medicines during pregnancy or lactation.

Published: July 2018

Background: Pain is one of the most frequent symptoms in older adults. It severely impairs quality of life, increases delirium risk, and may lead to progression of dementia. Assessment of pain performed by taking anamnesis from the patient is not reliable in patients with dementia due to cooperation and communication problems. The aim of this study was to assess pain and its consequences in patients with dementia. Methods: Seventy-five nursing home residents with dementia were enrolled. After comprehensive geriatric assessment, presence of pain was asked to patients, and Pain Assessment in Advanced Dementia (PAINAD), Discomfort Scale for Dementia of the Alzheimer’s Type (DS-DAT), Pain Assessment for the Dementing Elderly (PADE), Wong-Baker Faces Pain Rating Scale, and Numeric Rating Scale tests were performed. Results: Mean age was 81.1 (7.0), and 46.7% (n = 35) were female. Thirty-two percent of the patients were at early stage, 24% at moderate stage, and 44% at severe stage. Although the number of patients declaring pain was lower in moderate and severe stage, scores of PADE, PAINAD, and DS-DAT were significantly higher in severe stage showing the presence of pain ( P < .001). Furthermore, scores of PADE, PAINAD, and DS-DAT were negatively correlated with comprehensive geriatric assessment test scores. Conclusion: These results demonstrate that pain is not rare in patients with dementia, but they are not usually capable of expressing it, especially in the severe stage. Therefore, objective pain assessment scales developed for patients with dementia should be routinely used and management of pain should be done regarding the association of pain with other geriatric syndromes.

Published: July 2018

Background and Aims: The Swedish National Patient Insurance Company (LÖF) can compensate patients who believe they have been exposed to an avoidable injury or malpractice in healthcare. Its register covers 95% of Swedish healthcare providers. Material and Methods: Data on patients operated for primary or incisional ventral hernia in Sweden between 2010 and 2015 and who had filed a claim, were retrieved from LÖF. A total of 290 cases were identified and included. Files include a copy of records, relevant imaging, and an expert advisor’s opinion. Results: Inadvertent enterotomy occurred during 25 repairs and in these cases, laparoscopic repair was clearly overrepresented ( p  < 0.001). Complications related to the surgical site (infection and ugly scar) were predominantly related to open repairs ( p  < 0.001). Twenty percentage (57/290) of the claims were directly related to an anesthetic mishap. Univariate ordinal regression showed that the odds of receiving a high reimbursement was significantly increased if laparoscopic repair was performed p  < 0.001 (odds ratio: 0.37; 95% confidence interval: 0.21–0.65). Sixty-three percentage of claims were filed by women. Conclusion: Inadvertent enterotomy is overrepresented, and the probability that a claim filed for an avoidable injury leads to high reimbursement is greater if laparoscopic repair is performed rather than open ventral hernia repair. The high amount of injuries related to general anesthesia during umbilical hernia repair may be reduced with an increased proportion executed in local anesthesia.

Published: July 2018

Background People with intellectual disability are believed to be at risk of receiving poor end-of-life care. Nurses, given their advocacy role and duty to provide compassionate end-of-life care, have the potential to change this situation but research regarding this aspect of their role is limited. Aims This paper thus seeks to answer the question ‘How and when are nurses involved in providing care at end of life for people with intellectual disability?’ Methods A total of 38 intellectual disability care providers in the UK providing support to 13,568 people with intellectual disability were surveyed. Data regarding 247 deaths within this population were gathered in two stages and subsequently entered into SPSSX for analysis. Results Findings revealed that the majority of deaths occurred between the ages of 50 and 69 years, the most commonly reported cause of death being respiratory problems. Both community and hospital-based nurses were involved in supporting individuals during their final 3 months of life, and sometimes more than one type of nurse provided support to individuals. Generally nursing care was rated positively, although room for improvement was also identified. Conclusions Nurses are involved in supporting people with intellectual disability at end of life and appropriate education is required to undertake this role. This may require change in curricula and subsequent research to determine the impact of such change on nursing support to this population.
The presence and prevalence of Legionella spp in collected rainwater and its aerosolisation during common gardening activities
Authors: Steege L , Moore G 
Published: July 2018

Aims: To determine the presence and prevalence of Legionella spp in domestic rainwater storage butts and to quantify its aerosolisation when collected rainwater is used for common gardening activities. Methods: Volunteers were asked to take a water sample from their garden rainwater storage butt. The presence of Legionella was determined using quantitative polymerase chain reaction (qPCR). Two new rainwater storage butts were installed on-site at PHE Porton and positioned in sunlight or in the shade. Ambient conditions and those within the two ‘experimental’ water butts were continually monitored. A cyclone air sampler was used to detect the presence of Legionella in the air when collected rainwater was poured from a watering can or delivered via a hosepipe attached to a submersible water butt pump. Results: A total of 63 volunteers provided water samples from 113 different rainwater storage butts. Legionella spp was detected in 107 of these samples at a mean concentration of 4.7 × 104 genomic units l–1. Two of these samples also contained L. pneumophila. The water butt positioned in the shade stored water at a significantly lower temperature than that exposed to sunlight. While the concentration of Legionella was significantly higher in this cooler water, meteorological conditions rather than conditions within the water butt had the greatest effect upon Legionella concentration. No Legionella was detected in the air when rainwater was poured from a watering can. However, using a hose pipe on a ‘fine spray’ setting increased both the number of organisms detected in the air and their dissemination. Conclusion: In this study, Legionella spp were common contaminants of collected rainwater. However, the use of rainwater for common gardening activities should not be discouraged. Aerosolisation of Legionella when using a watering can is minimal and any increased risk associated with hose pipe use can be mitigated by using a coarse spray setting.

Published: July 2018

Background In healthy population cohorts, resting heart rate above 90 bpm is associated with mortality from coronary heart disease, but it is not clear whether associations are present at lower heart rates or whether these associations differ between women. Methods The CALIBER resource of linked electronic health records from primary care, hospitalisations, myocardial infarction registry and cause-specific mortality in the UK was used to assess associations between resting heart rate and 12 fatal and non-fatal coronary, cardiac, cerebral and peripheral vascular cardiovascular diseases and death using Cox proportional hazard models. Results Among 233,970 patients, 29,690 fatal and non-fatal events occurred. Fully adjusted models showed that resting heart rate was not associated in men or women with cerebrovascular events. In men a resting heart rate of 70–79 bpm (29.1% of all men) versus less than 60 bpm was associated with an increased risk of heart failure (hazard ratio (HR) 1.65, 95% confidence interval (CI) 1.26–2.16), unheralded coronary death (HR 1.65, 95% CI 1.13–2.41), total cardiovascular events (HR 1.22, 95% CI 1.15–1.28) and all-cause mortality (HR 1.39, 95% CI 1.22–1.58). Women with a higher resting heart rate level of 80–89 bpm versus 60 bpm had a higher risk of total cardiovascular disease events (HR 1.17, 95% CI 1.07–1.24) and all-cause mortality (HR 1.21, 95% CI 1.07–1.35) compared to a resting heart rate less than 60 bpm. The risk was also present at higher heart rates (>90 bpm) for heart failure and sudden cardiac death. Conclusions A resting heart rate that clinicians currently consider as ‘normal’ in the general population is specifically associated with the incidence of certain major cardiovascular diseases and death, with the risk starting at lower resting heart rate levels in men compared to women. Further research is required to evaluate whether interventions to lower resting heart rate are warranted to prevent disease. The study is registered at: clinicaltrials.gov (ID: NCT01947361).
Feline gastric pneumatosis
Authors: Silveira Carla , Benigni Livia , Gugich Kaye , McClaran Janet Kovak 
Published: July 2018

Case summary A 9-year-old male neutered domestic shorthair cat was presented with a 2 day history of anorexia and vomiting. A minimum database, including a complete blood count, serum biochemistry profile and urinalysis were unremarkable apart from a toxic neutrophilic left shift and borderline proteinuria. Abdominal ultrasound revealed intramural gas entrapment with thinning of the gastric wall, a hypoechoic pancreas, peritoneal fluid and a small volume of peritoneal gas along with a hyperechoic mesentery. CT was performed and demonstrated gas within the gastric submucosa and gas in the peritoneal cavity. Generalised gastric erythema was present at surgery and histopathology of excised abnormal areas reported gastric erosion with no obvious causative agents; however, pretreatment with dexamethasone may have been a contributing factor. Culture from biopsied gastric tissue was sterile. Clinical signs resolved after partial gastrectomy and medical management. Relevance and novel information Feline gastric pneumatosis is a rare clinical finding. Imaging is essential for diagnosis and to decide on the appropriate treatment; this is often medical but in cases where there is suspicion or evidence of gastric perforation, surgery is indicated. To our knowledge, this is the first case of feline gastric pneumatosis secondary to gastric ulceration, diagnosed via CT and where dexamethasone may have been a contributing factor.

Compartmentalisation of the respiratory tract microbiota in patients with different chronic obstructive pulmonary disease (COPD) severity degrees needs to be systematically investigated. In addition, it is unknown if the inflammatory and emphysematous milieux in patients with COPD are associated with changes in the respiratory tract microbiota and host macrophage gene expression.We performed a cross-sectional study to compare non-COPD controls (n=10) to COPD patients (n=32) with different disease severity degrees. Samples (n=187) were obtained from different sites of the upper and lower respiratory tract. Microbiota analyses were performed by 16S ribosomal RNA gene sequencing and host gene expression analyses by quantitative real-time PCR of distinct markers of bronchoalveolar lavage cells.Overall, the microbial communities of severe COPD (Global Initiative for Chronic Obstructive Lung Disease (GOLD) grade 3/4) patients clustered significantly differently to controls and less severe COPD (GOLD 1/2) patients (permutational multivariate ANOVA (MANOVA), p=0.001). However, we could not detect significant associations between the different sampling sites in the lower airways. In addition, the chosen set of host gene expression markers significantly separated COPD GOLD 3/4 patients, and we found correlations between the composition of the microbiota and the host data.In conclusion, this study demonstrates associations between host gene expression and microbiota profiles that may influence the course of COPD.

Abstract
Background
Glioblastoma (GBM) is the most common, malignant, and lethal primary brain tumor in adults accounting for about 50% of all gliomas. Up to now, the chemotherapy approaches for GBM were limited. 3-O-acetyl-11-keto-β-boswellic acid (AKBA), the major active ingredient of the gum resin from Boswellia serrata and Boswellia carteri Birdw., was reported to inhibit the growth of many types of cancer cells; however, the underlying mechanism of its anticancer effects are still unclear.

Methods
The effects of AKBA on cell viability and its cytotoxicity were determined using CCK8 and LDH kits respectively. The EdU-DNA synthesis assay was used to evaluate inhibition of cell proliferation by AKBA. The role of AKBA in glioblastoma cell functions such as migration/invasion, and colony formation was evaluated using transwell chambers and soft agar, respectively. Flow cytometry and western blotting were used to detect AKBA-induced apoptosis. Potential mechanisms of AKBA action were explored by RNA sequencing and the identified hub genes were validated by real-time quantitative PCR and western blotting. Finally, the in vivo anti-tumor activity of AKBA was evaluated against a human glioblastoma cell line, U87-MG, in a xenograft mouse model.

Results
AKBA inhibited cell proliferation, caused the release of LDH, decreased DNA synthesis, and inhibited the migration, invasion, and colony formation of U251 and U87-MG human glioblastoma cell lines. AKBA increased apoptosis as well as the activity of caspase 3/7 and the protein expression of cleaved-caspase 3 and cleaved PARP, while decreasing mitochondrial membrane potential. RNA-sequencing analyses showed that AKBA suppressed the expression of pRB, FOXM1, Aurora A, PLK1, CDC25C, p-CDK1, cyclinB1, Aurora B, and TOP2A while increasing the expression of p21 and GADD45A. These findings were validated by qRT-PCR and western blotting. The data are consistent with a mechanism in which AKBA arrested the cell cycle in glioblastoma cells at the G2/M phase by regulating the p21/FOXM1/cyclin B1 pathway, inhibited mitosis by downregulating the Aurora B/TOP2A pathway, and induced mitochondrial-dependent apoptosis. Oral administration of AKBA (100 mg/kg) significantly suppressed the tumorigenicity of U87-MG cells in a xenograft mouse model.

Conclusions
Taken together, these results suggest that AKBA (molecular weight, 512.7 Da) might be a promising chemotherapy drug in the treatment of GBM.
The volatilome – investigation of volatile organic metabolites (VOM) as potential tumor markers in patients with head and neck squamous cell carcinoma (HNSCC)
Authors: Opitz Philipp , Herbarth Olf 
Published: July 2018

Background Different organisms such as bacteria, molds and humans produce and release a relative unknown class of metabolites which are responsible for the individual olfactory pattern. These volatile organic metabolites (VOM) represent a kind of biosignature that reflects the sum of all multifactorial influences, including genetics, environmental factors, nutritional and disease status. As a result of pathological processes the individual body odor can be influenced by newly produced or altered compositions of the VOM. Until now, human VOM have been detected in various body media, such as on the skin, in the exhaled air as well as in body fluids such as saliva, mother's milk, sweat, blood and urine. Methods In this retrospective case-control study urinary VOM of 53 therapy-naive patients with head and neck squamous cell carcinoma (HNSCC) and 82 healthy controls were semi-quantified by headspace solid-phase micro extraction (SPME) gas chromatography (GC) mass spectrometry (MS). At first, the procedure was optimized in respect to the extraction parameters. By using Student's t-test significant differences in the VOM pattern with the corresponding p-values were obtained. For multivariate metabolite pattern recognition the hierarchical cluster analysis by Ward was applied, followed by the supervised partial least squares-discriminant analysis (PLS-DA). Results In total 81 VOMs could identified in the urine samples of all study participants, of which 25 were significantly increased and of which were 10 significantly reduced in HNSCC-patients compared to the controls. In addition, the multivariate statistics confirmed that on the basis of the renal excreted pattern of the volatile metabolites a high discrimination can be carried out between patients with a tumor in the head and neck region and controls. The substance group of the saturated, unbranched aldehydes makes a substantial contribution in this context. Conclusions The systematic pattern analysis of urinary VOMs appears to have potential clinical application as a diagnostic tool for cancer, especially HNSCC.
Early Motor Unit Conduction Velocity Changes to High-Intensity Interval Training versus Continuous Training
Authors: MARTINEZ-VALDES EDUARDO , FARINA DARIO , NEGRO FRANCESCO , DEL VECCHIO ALESSANDRO , FALLA DEBORAH 
Published: July 2018

ABSTRACT

Purpose
Moderate-intensity continuous training (MICT) and high-intensity interval training (HIIT) are associated with different adjustments in motor output. Changes in motor unit (MU) peripheral properties may contribute to these adjustments, but this is yet to be elucidated. This study evaluated early changes in MU conduction velocity (MUCV) and MU action potential amplitude after 2 wk of either HIIT or MICT.

Methods
Sixteen men were assigned to either an MICT group or HIIT group (n = 8 each), and participated in six training sessions over 14 d. HIIT: 8 to 12 × 60-s intervals at 100% peak power output. Moderate-intensity continuous training: 90 to 120 min continuous cycling at ~65% V˙O2peak. Preintervention and postintervention, participants performed maximal voluntary contractions (MVC) and submaximal (10%, 30%, 50%, and 70% of MVC) isometric knee extensions while high-density EMG was recorded from the vastus medialis (VM) and vastus lateralis (VL) muscles. The high-density EMG was decomposed into individual MU by convolutive blind-source separation and tracked preintervention and postintervention.

Results
Both training interventions induced changes in MUCV, but these changes depended on the type of training (P < 0.001). The HIIT group showed higher values of MUCV after training at all torque levels (P < 0.05), MICT only displayed changes in MUCV at low torque levels (10%–30% MVC, P < 0.002). There were no changes in MU action potential amplitude for either group (P = 0.2).

Conclusions
Two weeks of HIIT or MICT elicit differential changes in MUCV, likely due to the contrasting load and volume used in such training regimes. This new knowledge on the neuromuscular adaptations to training has implications for exercise prescription.
Reducing Impact Loading in Runners: A One-Year Follow-up
Authors: BOWSER BRADLEY J , FELLIN REBECCA , MILNER CLARE E. , POHL MICHAEL B. , DAVIS IRENE S. 
Published: July 2018

ABSTRACT
Increased vertical impact loading during running has been associated with a variety of running related injuries including stress fractures, patellofemoral pain, and plantar fasciitis.

Purpose
The purpose of this study was to examine the acute and long-term effect of a gait retraining program aimed at teaching runners with high impact loading to run softer.

Methods
Nineteen runners with high tibial shock (TS) first underwent a control period of eight sessions of treadmill running over 2 wk, progressing from 15 to 30 min. This was followed by eight sessions of gait retraining over 2 wk using the identical treadmill protocol. Real-time feedback of TS was provided as the participant ran. Feedback was gradually removed during the last four sessions. Variables of interest included peak TS, vertical impact peak and vertical average loading rate, and vertical instantaneous loading rate. These variables were assessed at intervals following the retraining and at a 1-yr follow-up.

Results
All variables of interest were significantly reduced post-retraining (P < 0.001). TS was reduced by 32%, vertical impact peak by 21%, vertical instantaneous loading rate by 27%, and vertical average loading rate by 25%. All variables continued to be significantly reduced at a 1-yr follow-up.

Conclusions
Impact loading can be reduced through gait retraining and the results persist at least 1 yr. As impact loading is associated with injury, this simple intervention may provide a powerful method of reducing musculoskeletal injury risk in runners.
