Audit of preoperative localisation of tumor with tattoo for patients undergoing laparoscopic colorectal surgery
Authors: Saleh A , Ihedioha U , Babu B , Evans J , Kang P 
Published: July 2015

Background Preoperative localisation of tumour is an essential requirement in laparoscopic colorectal surgery. Since the introduction of laparoscopic colorectal resections in NGH in February 2010, the difficulties of tumour localisation at the time of surgery without tattoo have been highlighted. Furthermore, endoscopic documentation of site of tattoo with respect to the tumour can be inconsistent and at times misleading or difficult to interpret. Tattooing guidelines should be simple to follow and consistent for all lesions irrespective of the location of the tumour. The recommendations were to place at least three spots of tattoo one mucosal fold distal to the lesion and clearly document site of tattoo with respect to tumour in the endoscopy report. Method We identified 100 patients undergoing elective laparoscopic colorectal cancer resections over a two-year period. Data were collected regarding presence of tattoo preoperatively as documented in the colonoscopy report and subsequently the visibility of the tattoo at time of laparoscopy and its accuracy in relation to the tumour. Abdominoperineal resections and emergency colorectal operations were excluded. Results Only 59% of the patients had a visible and accurate tattoo. In 17% of the patients, the tattoo was not visible at all, although it was documented in the endoscopy report that it had been administered. In 4% of patients, it was visible but inaccurately placed. In 20% of the patients, there were no tattoos at all, necessitating on table endoscopy and intraoperative specimen analysis to confirm that the tumour/lesion was within the resection specimen. Discussion Preoperative tumour localisation is extremely important to correctly identify the site of tumour or lesion at laparoscopy. A standardised departmental protocol should be implemented by all endoscopists to place three spots of tattoo one mucosal fold distal to any significant lesions found. Failure to tattoo lesions/cancers preoperatively can lead to intraoperative delays and potential harm to patients from on-table endoscopy.

Published: July 2015

Objective To evaluate right iliac vein and left iliac vein compression in asymptomatic subjects, right-sided and left-sided iliofemoral deep vein thrombosis patients. Methods A retrospective analysis of records and computed tomography images was conducted in 200 asymptomatic subjects (male:female, 100:100). A prospective analysis was conducted in 79 consecutive deep vein thrombosis patients (left:right deep vein thrombosis, 47:32) who had undergone contrast-enhanced computed tomography examination. The minor diameter and percentage compression of the iliac vein were evaluated. Results In asymptomatic subjects, 13.5% had right iliac vein compression >50%, 2.0% had right iliac vein compression >70%, mean compression was 23.48%; 45.0% had left iliac vein compression >50% and 17.0% had left iliac vein compression >70%, mean compression was 47.58%. Right iliac vein sandwiched between the right external iliac artery and the right internal iliac artery was the most common compression pattern (59.26%). Males had higher right iliac vein compression than the females (male:female, 26.29%:20.68%, P < 0.001). Mean percentage compression of the right iliac vein was higher in right deep vein thrombosis patients than in left deep vein thrombosis patients (right:left deep vein thrombosis, 48.54%:22.29%, P < 0.001). Conclusion Similar to left iliac vein compression, right iliac vein compression was a frequent imaging finding in CT and represented a normal anatomic pattern. Right deep vein thrombosis patients had more serious right iliac vein compression than left deep vein thrombosis patients, and further research is required on the association of right iliac vein compression with right iliofemoral deep vein thrombosis.

Authors: Martin Kristy-Jane , Sinclair Emma J , dasNair Roshan 
Published: July 2015

Objective: To establish what aspects of group-based cognitive rehabilitation for memory problems are reported, and to develop a checklist for authors, which may to improve reporting of these interventions in future studies. Data sources: A systematic search was conducted on Web of Knowledge, CINAHL, MEDLINE, AMED, EMBASE and PsycINFO electronic databases (last search: 01/05/2015). Review methods: Articles were included if the sample were adults with a neurological disorder, the intervention was group-based cognitive rehabilitation for memory problems, and if the study was a randomised controlled trial. Articles were independently screened for inclusion and data extracted by two researchers, with the third researcher arbitrating any disputes. Results: Fourteen studies were included in this review. The reporting of certain aspects of an intervention was found to be poor, particularly in relation to: duration of the programme (6 of 14 studies did not report), the development of the intervention (7 of 14 studies did not discuss), and the content and structure of intervention (7 of the 14 studies did not provide details). Conclusion: This review found that the overall reporting of memory rehabilitation content and format is poor. Refinement and adaption of pre-existing checklists to capture aspects of cognitive rehabilitation programmes may help authors when reporting complex interventions. A draft checklist is provided that could be refined and validated in further research.

Published: July 2015

Background: There are no long-term prospective controlled trials comparing postoperative regimens after Achilles tendon rupture repair. Purpose: To compare ≥10-year outcomes of 2 postoperative regimens after Achilles tendon rupture repair: early weightbearing with early mobilization versus early weightbearing with early immobilization in tension. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A total of 50 patients with acute Achilles tendon ruptures were randomized postoperatively to receive either early movement of the ankle between neutral and plantar flexion in a brace for 6 weeks (group 1) or Achilles tendon immobilization in tension using a below-knee cast with the ankle in a neutral position for 6 weeks (group 2). Patients were assessed at 3, 6, and 14 months and 11 years postoperatively. Results: There were 37 patients (74%) evaluated at a mean (±SD) of 11.0 ± 0.9 years. The mean Leppilahti score was 92.9 ± 5.6 in group 1 and 93.6 ± 7.2 in group 2 ( P = .68). The mean isokinetic plantar flexion peak torque deficits or average work deficits in plantar flexion showed no differences between the groups with any angular velocity. Isokinetic strength changed minimally between 1 and 11 years compared with the unaffected ankle, but a mean deficit of 5% in peak torque and mean deficit of 8% in average work were still present after 11 years. On the contrary, isometric plantar flexion strength recovered significantly, with only a 2.4% difference at 11-year follow-up. Conclusion: After the 11-year follow-up, early mobilization and immobilization in tension after Achilles rupture repair resulted in similar clinical outcomes and isokinetic strengths. Regardless of patient satisfaction with the operative treatment, calf muscle strength did not recover normally even at 11-year follow-up.
Women’s Malnutrition in India: The Role of Economic and Social Status
Authors: Dahiya Shikha , Viswanathan Brinda 
Published: July 2015

This study has used data from the India Human Development Survey (IHDS), 2005–06, to study the factors influencing the body mass index (BMI) of women between 20 and 40 years of age in India. BMI captures both undernutrition and over-nutrition, and a quantile regression model has been used to capture the differential impact of the explanatory variables across the wide range of its values. Variables such as per capita income, per capita consumption expenditure and wealth are important in explaining variations in BMI, but the impact varies across the quantiles. The impact of per capita consumption expenditure is greater than that of per capita income, indicating the effectiveness with which resources are converted to consumption. Higher levels of wealth status affect BMI more across all the quantiles. Women’s autonomy index shows a positive impact only for higher levels of the index value, but the magnitude is very small, while caste and religion play an important role even after controlling for economic status.

Authors: Kroll Amanda L , Corrigan Patricia A , Patel Shejal , Hawks Kelly G 
Published: July 2015

Introduction Up until 2010, the recommended duration of empiric broad-spectrum antibiotics for febrile neutropenia was until absolute neutrophil count (ANC) recovery. An updated guideline on the use of antimicrobial agents in neutropenic patients with cancer indicates that patients who have completed an appropriate treatment course of broad-spectrum antibiotics, with resolution of signs and symptoms of infection but persistent neutropenia, can be de-escalated to oral fluoroquinolone prophylaxis until ANC recovery. Methods The primary objective of this retrospective investigation was to evaluate the safety and efficacy of de-escalating broad-spectrum antibiotics in patients remaining neutropenic after at least 14 days of empiric broadspectrum antibiotics for febrile neutropenia compared to patients continuing broad-spectrum antibiotics until ANC recovery. Results There were 16 patients (61.5%) in the comparator group who met the primary endpoint of remaining afebrile and without escalation of antibiotics for at least 72 hours after 14 days of broad-spectrum antibiotics and 21 patients (80.7%) in the de-escalation group who met the primary endpoint of remaining afebrile and without reinitiation of broad-spectrum antibiotics for at least 72 hours after de-escalation to levofloxacin therapy ( p = 0.11). Mean total duration of broad-spectrum antibiotic therapy was 23.5 ± 1.5 days in the comparator group versus 22.2 ± 1.43 days in the de-escalation group ( p = 0.39). Conclusions Results of this investigation indicate that broad-spectrum antibiotics can be safely de-escalated to levofloxacin prophylaxis prior to ANC recovery in select patients. This practice may decrease the duration of broad-spectrum antibiotic exposure and associated complications.
The Impact and Treatment of Obesity in Kidney Transplant Candidates and Recipients
Authors: Chan Gabriel , Garneau Pierre , Hajjar Roy 
Published: July 2015

The prevalence of obesity in patients with chronic kidney failure and renal transplant candidates has paralleled the epidemic in the general population. The associated risks of surgical complications and long-term cardiovascular death are significant: most transplant centers consider obesity a relative contra-indication for transplant. Few studies have focused on conservative weight loss strategies in transplant patients. Studies using administrative databases have found that only a minority of wait-listed patients lose weight and with no apparent benefit to transplant outcomes. The only clinical trial in this area found that an intensive weight-loss program had significantly better success (to listing) than self-directed weight loss. However, only a minority that succeeded with the help of a program (36 %), while the “diet and exercise” group had negligible results. Laparoscopy has radically shortened the recovery time and decreased the complications associated with bariatric surgery. Reports in transplant patients, who were previously deemed too medically complex, have demonstrated a dramatic and rapid weight loss. The only randomized clinical trial in patients with CKD, which compared sleeve gastrectomy to best medical care clearly favoured the surgical arm for weight loss, but was too small to assess other outcomes. The emerging experience is small but quite promising. Surgical complications and the effect on immunosuppression remain the chief concerns regarding the use of bariatric surgery in transplant patients. Rigorous prospective studies will be essential to properly evaluate the expected weight loss and the effect on pharmacokinetics of immunosuppressive medications. A routine role for bariatric surgery in transplantation would require evidence of improvements in patient-important outcomes and evidence of safety.
Online Checkpointing with Improved Worst-Case Guarantees
Authors: Bringmann Karl , Doerr Benjamin , Neumann Adrian , Sliacan Jakub 
Published: July 2015

In the online checkpointing problem, the task is to continuously maintain a set of k checkpoints that allow rewinding an ongoing computation faster than by a full restart. The only operation allowed is to replace an old checkpoint by the current state. Our aim is checkpoint placement strategies that minimize rewinding cost, i.e., such that at all times T when requested to rewind to some time t ≤ T the number of computation steps that need to be redone to get to t from a checkpoint before t is as few as possible. In particular, we want the closest checkpoint earlier than t to be no farther away from t than qk times the ideal distance T/(k + 1), where qk is a small constant. Improving earlier work showing 1 + 1/k ≤ qk ≤ 2, we show that qk can be chosen asymptotically less than 2. We present algorithms with asymptotic discrepancy qk ≤ 1.59 + o(1) valid for all k and qk ≤ ln(4) + o(1) ≤ 1.39 + o(1) valid for k being a power of two. Experiments indicate the uniform bound pk ≤ 1.7 for all k. For small k, we show how to use a linear programming approach to compute good checkpointing algorithms. This gives discrepancies of less than 1.55 for all k < 60. We prove the first lower bound that is asymptotically more than 1, namely qk ≥ 1.30 − o(1). We also show that optimal algorithms (yielding the infimum discrepancy) exist for all k.
Equine neonates and infection control
Authors: Smeddle Suzannah 
Published: July 2015

Providing nursing care to equine neonates requires the veterinary nurse to have specific skills, clinical experience and a comprehensive understanding of infection control. There are many factors that should be considered when a neonate is hospitalised, such as the ability to separate the foal from the mare and the proximity of the accommodation to other inpatients. When considering the development of new biosecurity protocols for equine neonatal nursing there are several lessons that could be learned from studies in the human nursing field. Reflecting on veterinary nursing care is essential as it facilitates progress and improves the quality of patient care.
Spreading the message! Fanzines and the punk scene in Portugal1
Authors: Guerra Paula , Quintela Pedro 
Published: July 2015

Abstract
Even though the production of fanzines precedes the emergence of punk, the truth is that it was with punk that the fanzines become relevant as a space for freedom of thought and creation, as well as an alternative to the conventional media. Since the 1970s, the fanzines’ universe has expanded thematically and stylistically, and also in its territorial coverage and in the communicational supports used. In this article we adopt an approach that goes beyond the Anglo-Saxon reality and intend to look at fanzines as ‘communities’ founded around a cultural object, which have produced texts, photos and other materials regarding the Portuguese punk scene from the late 1970s until now. From a large set of fanzines we will analyse the ways of production, design and typography, the main themes, distribution channels, bands, the scenes and lifestyles covered in them. In this study, we consider fanzines to be an alternative media that, from late modernity, is able to reveal the punk movement and the DIY ethos associated with it. We seek to understand fanzines’ relevance to the Portuguese punk scene context, both past and present, and we also identify some patterns of evolution and change.

Perception sensor modeling for virtual validation of automated driving
Authors: Cao Peng , Wachenfeld Walther , Winner Hermann 
Published: July 2015

Abstract
The automotive innovations in the last decades are dominated by new
software-based functions. A validation of these functions is always
needed for ensuring the safety of the vehicles. XiL-methods are widely
used for this purpose. Along with the development of automated driving
vehicles, the demand for simulation based validation of such vehicles
is rising, as shown by examples. For the simulations, the modeling of
the perception sensors plays an essential role. A state-of-the-art
survey clarifies, that a dilemma between simulation efficiency and
fidelity of the current methods exists, especially when modeling
active sensors. A novel concept of grey box modeling promises to solve
the dilemma, or at least to defuse it. With a generalized sensor
structure and a simplified propagation modeling, the grey box model
considers the most important physically based performances of the
sensors and their ranges. The basic structure of the modeling is
sketched here, and an outlook for future requirements on it is
presented.
Constraining the Conformational Landscape of a Polyether Building Block by Raman Jet Spectroscopy
Authors: Bocklitz Sebastian , Suhm Martin A. 
Published: July 2015

Abstract
Collisionally induced chain isomerization of CH3OCH2CH2OCH3
around its three central torsional angles is characterized in
a supersonic slit jet by probing compound-seeded carrier gas expansions
with focussed 5–25 W cw 532 nm radiation as
a function of carrier gas, nozzle temperature and
distance. Spontaneously Raman scattered photons are collected and
dispersed down to 100 cm
–1. They reveal important
contributions from three chain conformations in the
expansion. Isomerization around the outer torsional angle is found to
be feasible, whereas the central OCCO angle remains largely
conserved under most expansion conditions. The spectroscopic results
are used for a critical assessment of quantum-chemical predictions for
the energy sequence of the three low-lying conformations. The
stretched global minimum energy structure of this polyether building
block is consistent with a statistical model of the dominant
unimolecular relaxation pathways.
Breath-Alcohol Analysis:Uses, Methods, and Some Forensic Problems—Review and Opinion
Authors: Mason MF , Dubowski KM 
Published: July 2015

Abstract
Presently when one uses the terms “breath analysis,” “breath testing,” or even the unqualified “chemical testing,” people, generally, think of a determination of alcohol in a specimen of breath for medicolegal purposes. (The unmodified term “alcohol” in this article refers to ethanol.) This is because of the notoriety of this application and, perhaps, the strong resentment of many to the police procedures involved. Actually, analysis of breath has been undertaken for a variety of purposes since before the recorded history of man. Thus an almost infinite number of conscious judgments about, or unconscious responses to, components of his inspired breath have been made based on odor, taste, and other sensory effects, many of these crucial for well-being or survival of both man and other animals. A striking example is the functioning of pheromones [1].

Abstract
In 1970, a five-month-old baby was admitted to a California hospital. The X-rays showed that his skull was fractured from ear to ear. His mother explained that the baby had fallen off a bed. The child was returned to the mother three days later. Twice within the next four weeks further medical treatment was required for injuries which included whip welts on the back, puncture wounds in the neck, and burned fingertips. The last time he was brought in he had strangulation marks and no respiration. Spontaneous respiration was restored but the baby suffered extensive brain damage. As a result, this small child will be confined in a home for the mentally retarded for the rest of his life. Time reported that The mother's boyfriend was convicted of child beating and sentenced to from one to ten years in prison (the mother.., was not charged ...). Meanwhile, the child's father brought a $5,000,000 suit against four doctors, for failing to report the attacks, and against the city and police chief ... for failing to investigate when another doctor did make charges.[1]
Determination of Fluoride by Specific Ion Electrode and Report of a Fatal Case of Fluoride Poisoning
Authors: Speaker JH 
Published: July 2015

Abstract
Postmortem fluoride levels in fluoride poisoning cases can be measured conveniently with the specific ion or ion-sensitive electrode. Earlier techniques commonly used complexing agents and depended on colorimetric quantitation [1–6]. Separation of fluoride from the postmortem specimens was achieved by several means including microdiffusion [3–6]. The specific ion electrode measurement of fluoride has been employed directly in urine and other fluids and after separation of the fluoride from biological specimens [6–10]. The subjects of this report are a method combining microdiffusion as a separation procedure with specific ion electrode quantitation of fluoride and the results obtained from a case in which this method was used.
