Abstract
BACKGROUND Heart failure is a complex clinical syndrome noted on approximately 1 in 8 death certificates in the United States. Vital to reducing complications of heart failure and preventing hospital readmissions is adherence to heart failure self-care routines. Mobile health offers promising opportunities for enhancing self-care behaviors by facilitating tracking and timely reminders. OBJECTIVE We sought to investigate three characteristics of heart failure patients with respect to their heart failure self-care behaviors: (1) internet use to search for heart failure information; (2) familiarity with mobile health apps and devices; and (3) perceptions of using activity trackers or smartwatches to aid in their heart failure self-care. METHODS Forty-nine heart failure patients were asked about their internet and mobile health usage. The structured interview included questions adapted from the Health Information National Trends Survey. RESULTS Over 50% of the patients had utilized the internet to search for heart failure information in the past 12 months, experience using health-related apps, and thoughts that an activity tracker or smartwatch could help them manage heart failure. Qualitative analysis of the interviews revealed six themes: trust in their physicians, alternatives to mobile health apps, lack of need for mobile health devices, financial barriers to activity tracker and smartwatch ownership, benefits of tracking and reminders, and uncertainty of their potential due to lack of knowledge. CONCLUSIONS Trust in their physicians was a major factor for heart failure patients who reported not searching for health information on the internet. While those who used mobile health technologies found them useful, patients who did not use them were generally unaware of or unknowledgeable about them. Considering patients' preferences for recommendations from their physicians and tendency to search for heart failure information including treatment and management options, patient-provider discussions about mobile health may improve patient knowledge and impact their usage.

CTP-based estimated ischemic core: A comparative multicenter study between Olea and RAPID software. J Stroke Cerebrovasc Dis 2023; 32:107297. [PMID: 37738915 DOI: 10.1016/j.jstrokecerebrovasdis.2023.107297] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 08/01/2023] [Accepted: 08/03/2023] [Indexed: 09/24/2023] Open
Abstract
BACKGROUND AND PURPOSE CTP is increasingly used to assess eligibility for endovascular therapy (EVT) in patients with large vessel occlusions (LVO). There remain variability and inconsistencies between software packages for estimation of ischemic core. We aimed to use heterogenous data from four stroke centers to perform a comparative analysis for CTP-estimated ischemic core between RAPID (iSchemaView) and Olea (Olea Medical). METHODS In this retrospective multicenter study, patients with anterior circulation LVO who underwent pretreatment CTP, successful EVT (defined TICI ≥ 2b), and follow-up MRI included. Automated CTP analysis was performed using Olea platform [rCBF < 25% and differential time-to-peak (dTTP)>5s] and RAPID (rCBF < 30%). The CTP estimated core volumes were compared against the final infarct volume (FIV) on post treatment MRI-DWI. RESULTS A total of 151 patients included. The CTP-estimated ischemic core volumes (mean ± SD) were 18.7 ± 18.9 mL on Olea and 10.5 ± 17.9 mL on RAPID significantly different (p < 0.01). The correlation between CTP estimated core and MRI final infarct volume was r = 0.38, p < 0.01 for RAPID and r = 0.39, p < 0.01 for Olea. Both software platforms demonstrated a strong correlation with each other (r = 0.864, p < 0.001). Both software overestimated the ischemic core volume above 70 mL in 4 patients (2.6%). CONCLUSIONS Substantial variation between Olea and RAPID CTP-estimated core volumes exists, though rates of overcalling of large core were low and identical. Both showed comparable core volume correlation to MRI infarct volume.

Abstract
We report on the synthesis of hybrid light emitting particles with a diameter ranging between 100 and 500 nm, consisting in a compact semiconductor CdSe/CdS/CdZnS nanocrystal aggregate encapsulated by a controlled nanometric size silica and gold layers. We first characterize the Purcell decay rate enhancement corresponding to the addition of the gold nanoshell as a function of the particle size and find a good agreement with the predictions of numerical simulations. Then, we show that the contribution corresponding to Förster resonance energy transfer is inhibited.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study. Lancet Digit Health 2022; 4:e520-e531. [PMID: 35750401 DOI: 10.1016/s2589-7500(22)00069-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 01/07/2022] [Accepted: 04/06/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
BackgroundIn cancer immunotherapy, T-lymphocyte activation can lead to secondary autoimmune diseases named OASI for Opportunistic Autoimmunity Secondary to cancer Immunotherapy [1]. The epidemiology of OASI deserves to be further studied due to the unadapted reporting of clinical trials and the lack of prospective studies. Moreover, literature focuses on the most severe OASI and/or on specific OASI (myocarditis, colitis, arthritis).ObjectivesOur goal was to determine incidence, severity of all grade OASI using a multicentric prospective patient cohort starting treatment with cancer immunotherapy.MethodsWe present a multicentric, prospective, observational, longitudinal, real life, French e-cohort. 900 patients treated with ipilimumumab and/or nivolumab will be included. Data is collected from the patient and the oncologist at inclusion, then patients report directly any symptom that could be suggestive of OASI with the help of monthly digital questionaries. In case an OASI is suspected, further confirmation is made with the practician in charge and by a paired analysis with the Système National De Santé (SNDS), the French health insurance registry.ResultsOn the 19/01/2022, 439 patients were included, 310 males (70.6%) and 129 females (29.4%). Mean age is 66 years old with a median follow up of 192 days. 354 patients (80.6%) are treated with Nivolumab alone, 7 (1.6%) with Ipilimumab alone and 76 (17.8 %) with combined Nivolumab + Ipilimumab. 136 patients (31.6%) are treated for a non-small cell lung carcinoma, 107 patients (24.9%) for a clear cell renal carcinoma, 91 patients (21.2%) for a skin melanoma, 49 patients (11.4%) for a head or neck epidermoid carcinoma, 24 patients (5.6%) for another lung cancer sub-type, and 32 patients (5.3%) for another histological cancer type. The mean follow-up is 294 days (+/- 192). 83 patients (18.9%) died since the beginning of the follow up.47 patients (10.7%) developed 63 OASI. The mean delay between the beginning of cancer immunotherapy and the OASI is 134.7 days (+/- 103.4).Approximately, one third of the OASI were musculoskeletal diseases. The OASI included polymyalgia rheumatica (3 patients), psoriatic arthritis (1 patient), polyarthritis (1 patient) systemic lupus (1 patient), arthralgias and myalgias (8 patients), colitis (11 patients), dysthyroïditis (6 patients), hepatitis (4 patients), nephritis (3 patients), pneumonitis (2 patients), hypophysitis (2 patients), adrenal insufficiency (4 patients), myocarditis (1 patient), hemophagocytic lympho-histiocytosis (1 patient), and other types of OASI (15 patients).26 patients (55% of patients with OASI, 5,9% of all patients) had to stop cancer immunotherapy due to an OASI, one because of a rheumatic disease (systemic lupus). 52 patients were treated with corticosteroids, 1 patient with methotrexate (psoriatic arthritis), 3 patients with infliximab (colitis) and 1 patient with abatacept (myocarditis). 1 patient died after an OASI (colitis).ConclusionThe first results of this prospective study, using an original patient-centered methodology, confirm the expected incidence of autoimmune events secondary to cancer immunotherapy and the role of rheumatologists in their therapeutic management.References[1]Kostine M, Chiche L, Lazaro E, et al.

Abstract
Zusammenfassung
Hintergrund
Zu den Aufgaben in der rechtsmedizinischen Praxis gehören zunehmend forensisch-medizinische Untersuchungen von Lebenden. Im Gegensatz zu Studien über Gewaltopfer findet sich in der Fachliteratur allerdings ein erhebliches Defizit an Ergebnissen über systematische rechtsmedizinische Untersuchungen von Tatverdächtigen.
Fragestellung
Welche relevanten Daten können aus einer retrospektiven Analyse von forensisch-medizinischen Untersuchungen von Tatverdächtigen erhoben und welche Rückschlüsse für die rechtsmedizinische Praxis gezogen werden?
Material und Methode
Es wurden insgesamt 270 Gutachten nach forensisch-medizinischen Untersuchungen von Tatverdächtigen aus dem Einzugsgebiet des Instituts für Rechtsmedizin der Universitätsmedizin Rostock der Jahre 2006 bis 2018 nach vorab definierten Kriterien ausgewertet.
Ergebnisse
Die vorgeworfenen Straftaten waren am häufigsten Körperverletzungen (n = 88 = 30,7 %), gefolgt von vorsätzlichen Tötungen (n = 63 = 22,0 %) und Sexualdelikten (n = 49 = 17,1 %). Von den begutachteten Personen waren 236 (87,4 %) männlich und 34 (12,6 %) weiblich. Die Mehrzahl der Tatverdächtigen (n = 175 = 65,5 %) war in einem Lebensalter von 18 bis 40 Jahren.
Im Hinblick auf die Aussage der rechtsmedizinischen Ergebnisse in Bezug auf den vorgeworfenen Straftatbestand wurden 126 (46,7 %) Gutachten als für den Tatverdächtigen belastend, 13 (4,8 %) als entlastend und 131 (48,5 %) als frei von Be- oder Entlastungsaussagen eingestuft.
Zu den 270 Gutachten über Tatverdächtige gab es 209 (77,4 %) korrespondierende Opferuntersuchungen. Von diesem Teilkollektiv mit Täter-Opfer-Begutachtungen wurden in 193 Fällen (92,3 %) Tatverdächtige und Opfer von demselben Gutachter untersucht.
Schlussfolgerungen
Für die Rekonstruktion eines Tatgeschehens sind rechtsmedizinische Untersuchungen des Opfers und des Tatverdächtigen wertvoller als die nicht selten beobachtete Untersuchung der geschädigten Person allein. Befunde mit belastenden Tendenzen für den Tatverdächtigen werden häufiger festgestellt als solche, die zu einer Entlastung des Beschuldigten führen. Da es in der Fachliteratur im Vergleich zu den Opfern von Gewalttaten ein Defizit an Ergebnissen über systematische forensisch-medizinische Untersuchungen von Tatverdächtigen gibt, sollten weitere Studien folgen.

Abstract
BACKGROUND Cerebral palsy (CP) is the most common motor impairment in childhood and often accompanied by a broad spectrum of comorbidities. Data are sparse concerning visual impairment (VI) and functional classification among CP children. OBJECTIVE The objective of this study was to analyze the prevalence of VI among children with CP and to investigate a possible association between VI and Gross Motor Function Classification System (GMFCS) and the Bimanual Fine Motor Function (BFMF). METHODS In this hospital-based study, records of 200 children with CP aged 2 to 17 years were reviewed. RESULTS Overall, VI was found in 59.5% of children with CP. Prevalence of VI was higher when compared with non-CP children. A correlation between GMFCS as well as BFMF and severity of VI was found. Children with severe CP were at greater risk for severe VI, especially cerebral VI compared with children with mild CP. CONCLUSION VI is a significant problem in children with CP and is correlated with motor function. Children with CP should undergo detailed ophthalmologic and orthoptic assessment to enable early intervention.

Abstract
The rejection of composite veneerings in fixed partial dentures is primarily caused by the inadequacy of the bonds between the metal framework and the composite veneering. The development of improved veneering composites necessitates an investigation of their clinical suitability compared with ceramic materials. Nineteen patients with at least two suitable, adjacent natural teeth for crowning were treated with 64 high noble alloy crowns. The adjacent crowns were veneered with ceramic (IPS inline) and composite materials (SR Adoro). Seven follow-up examinations were carried out over a period of 10 years. The crowns were investigated for mechanical defects, periodontal parameters, and discolorations. The survival rates of the ceramic veneered metal crowns (CeMCs) and composite veneered metal crowns (CoMCs) at the 10-year follow-up were 87.1 and 87.9%, respectively. The success rates of the crowns after 10 years were 83.9% for CeMCs and 51.5% for CoMCs (log-rank test, p = 0.009). No significant differences between the groups were found in the periodontal parameters (Kruskal-Wallis one-way analysis of variance, ANOVA p ⟩ 0.05). After 10 years, discoloration patterns of the two materials differed significantly (Mann-Whitney-U-test, p = 0.017). Thus, despite the improvements associated with CoMCs, CeMCs remain the gold standard for veneered metal crowns.

Abstract
Abstract
Background
Food insecurity has a high prevalence among asylum seekers living in Western countries. Previous studies suggest that food skills can protect against food insecurity. This study investigates the impact of food skills on food security and dietary diversity among refugees living in Norwegian reception centers.
Methods
The study has a cross-sectional research design. Eight asylum reception centers where selected and 205 asylum seekers (131 men and 74 women) were recruited through convenience sampling among the largest asylum seeking groups. We measured food skills by adopting questions from the Canadian Community Health Survey 2013 Rapid Response on Food Skills. Food skills were divided into cooking skills (ability to prepare meals) and shopping skills (ability to plan meals and budgeting). Food security was measured with the 10-item version of the Radimer/Cornell Hunger and Food Insecurity Scale. Dietary data was collected via a 24-hour recall, and the Food and Agriculture Organization of the United Nations (FAO) dietary diversity score was calculated to assess dietary quality. Data were analyzed with bivariate logistic analysis.
Results
Cooking skills and shopping skills contribute differently to food security and dietary diversity. Higher cooking skills were associated with higher dietary diversity but not with food security. Shopping skills were not associated with either food security or dietary diversity. Women had better cooking skills then men, but there were no gender differences in shopping skills. Married asylum seekers had better shopping skills than those who were not married.
Conclusions
Cooking skills have an impact on dietary diversity, initiatives promoting cooking skills should be encouraged. Further research is needed on what kind of purchasing skills can be useful for asylum seekers coping. Despite high food skills the level of food insecurity remained high. Initiatives addressing the multiple causes of food insecurity are needed.
Key messages
Food skills alone do not protect from food insecurity. Cooking skills are easier to transfer in a new food environment than shopping skills.

Abstract
Eutectic NiAl-(Cr,Mo) composites are promising high temperature materials due to their high melting point, excellent oxidation behavior and low density. To enhance the strength, hardness and fracture toughness, high cooling rates are beneficial to obtain a fine cellular-lamellar microstructure. This can be provided by the additive process of selective electron beam melting. The very high temperature gradient achieved in this process leads to the formation of the finest microstructure that has ever been reported for NiAl-(Cr,Mo) in-situ composites. A very high hardness and fracture toughening mechanisms were observed. This represents a feasibility study towards additive manufacturing of eutectic NiAl-(Cr,Mo) in-situ composites by selective electron beam melting.

Resonant Inelastic X-Ray Scattering Reveals Hidden Local Transitions of the Aqueous OH Radical. PHYSICAL REVIEW LETTERS 2020; 124:236001.

Abstract
Resonant inelastic x-ray scattering (RIXS) provides remarkable opportunities to interrogate ultrafast dynamics in liquids. Here we use RIXS to study the fundamentally and practically important hydroxyl radical in liquid water, OH(aq). Impulsive ionization of pure liquid water produced a short-lived population of OH(aq), which was probed using femtosecond x-rays from an x-ray free-electron laser. We find that RIXS reveals localized electronic transitions that are masked in the ultraviolet absorption spectrum by strong charge-transfer transitions-thus providing a means to investigate the evolving electronic structure and reactivity of the hydroxyl radical in aqueous and heterogeneous environments. First-principles calculations provide interpretation of the main spectral features.

Abstract
Elementary processes associated with ionization of liquid water provide a framework for understanding radiation-matter interactions in chemistry and biology. Although numerous studies have been conducted on the dynamics of the hydrated electron, its partner arising from ionization of liquid water, H2O+, remains elusive. We used tunable femtosecond soft x-ray pulses from an x-ray free electron laser to reveal the dynamics of the valence hole created by strong-field ionization and to track the primary proton transfer reaction giving rise to the formation of OH. The isolated resonance associated with the valence hole (H2O+/OH) enabled straightforward detection. Molecular dynamics simulations revealed that the x-ray spectra are sensitive to structural dynamics at the ionization site. We found signatures of hydrated-electron dynamics in the x-ray spectrum.

Abstract
INTRODUCTION Acute myeloid leukaemia (AML) is an aggressive haematological malignancy which is more common in the elderly and has a poor 5-year survival. There are no established beneficial interventions to treat AML in elderly patients. It is unclear whether outpatient delivery of palliative chemotherapies could reduce the burden of disease and hospitalisation for this group. AIMS To compare overall survival, response to treatment and supportive care needs between inpatient and outpatient-based treatments for AML in elderly patients. MATERIALS & METHODS We undertook a retrospective cohort study in the Haematology Department at Belfast City Hospital comparing overall survival (OS), treatment responses and supportive care needs between inpatient and outpatient treatments for AML in elderly patients. Consecutive entrants to outpatient and inpatient based clinical trials between February 2013 and January 2017 were included. Case notes, chemotherapy charts, clinic letters, blood bank and electronic care records were analysed. RESULTS OS and rates of CR (complete remission), CRi (CR with incomplete count recovery) and PR (partial response) was not significantly different between inpatient and outpatient regimens with a median OS of 201 vs. 124 days, respectively. No response was observed in 35% of patients in the inpatient group compared with 65% of the outpatient group, however this did not reach significance. Of patients who achieved CR/CRi in the outpatient group, 75% relapsed at a median of 271 days, compared with 60% of the inpatient group at a median of 209 days. At least one grade 3-4 toxicity was experienced by 90% and 83.3% of inpatient and outpatient groups, respectively. There was no difference in six common grade 3-4 toxicities. Patients on the outpatient regimen spent fewer days in hospital but had a median packed red cell use of more than twice that of the inpatient group. No difference was noted in infections, days on antibiotics or platelet use. DISCUSSION Our data suggests that outpatient chemotherapy is safe and can reduce hospitalisation for elderly patients with AML, without a decline in OS or response rates. These results provide an important rationale to test the comparative efficacy of outpatient chemotherapy. Chemotherapy related toxicities remain a significant source of morbidity in this population and highlight the need to develop novel, targeted therapies for this age group.

Mycobacterium tuberculosis and whole-genome sequencing: how close are we to unleashing its full potential? Clin Microbiol Infect 2017; 24:604-609. [PMID: 29108952 DOI: 10.1016/j.cmi.2017.10.030] [Citation(s) in RCA: 74] [Impact Index Per Article: 10.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2017] [Revised: 10/21/2017] [Accepted: 10/30/2017] [Indexed: 01/16/2023]
Abstract
BACKGROUND Nearly two decades after completion of the genome sequence of Mycobacterium tuberculosis (MTB), and with the advent of next generation sequencing technologies (NGS), whole-genome sequencing (WGS) has been applied to a wide range of clinical scenarios. Starting in 2017, England is the first country in the world to pioneer its use on a national scale for the diagnosis of tuberculosis, detection of drug resistance, and typing of MTB. AIMS This narrative review critically analyses the current applications of WGS for MTB and explains how close we are to realizing its full potential as a diagnostic, epidemiologic, and research tool. SOURCES We searched for reports (both original articles and reviews) published in English up to 31 May 2017, with combinations of the following keywords: whole-genome sequencing, Mycobacterium, and tuberculosis. MEDLINE, Embase, and Scopus were used as search engines. We included articles that covered different aspects of whole-genome sequencing in relation to MTB. CONTENT This review focuses on three main themes: the role of WGS for the prediction of drug susceptibility, MTB outbreak investigation and genetic diversity, and research applications of NGS. IMPLICATIONS Many of the original expectations have been accomplished, and we believe that with its unprecedented sensitivity and power, WGS has the potential to address many unanswered questions in the near future. However, caution is still needed when interpreting WGS data as there are some important limitations to be aware of, from correct interpretation of drug susceptibilities to the bioinformatic support needed.

A comparison of two molecular methods for diagnosing leptospirosis from three different sample types in patients presenting with fever in Laos. Clin Microbiol Infect 2017; 24:1017.e1-1017.e7. [PMID: 29092789 PMCID: PMC6125144 DOI: 10.1016/j.cmi.2017.10.017] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2017] [Revised: 10/16/2017] [Accepted: 10/18/2017] [Indexed: 02/01/2023]
Abstract
OBJECTIVES To compare two molecular assays (rrs quantitative PCR (qPCR) versus a combined 16SrRNA and LipL32 qPCR) on different sample types for diagnosing leptospirosis in febrile patients presenting to Mahosot Hospital, Vientiane, Laos. METHODS Serum, buffy coat and urine samples were collected on admission, and follow-up serum ∼10 days later. Leptospira spp. culture and microscopic agglutination tests (MAT) were performed as reference standards. Bayesian latent class modelling was performed to estimate sensitivity and specificity of each diagnostic test. RESULTS In all, 787 patients were included in the analysis: 4/787 (0.5%) were Leptospira culture positive, 30/787 (3.8%) were MAT positive, 76/787 (9.7%) were rrs qPCR positive and 20/787 (2.5%) were 16SrRNA/LipL32 qPCR positive for pathogenic Leptospira spp. in at least one sample. Estimated sensitivity and specificity (with 95% CI) of 16SrRNA/LipL32 qPCR on serum (53.9% (33.3%-81.8%); 99.6% (99.2%-100%)), buffy coat (58.8% (34.4%-90.9%); 99.9% (99.6%-100%)) and urine samples (45.0% (27.0%-66.7%); 99.6% (99.3%-100%)) were comparable with those of rrs qPCR, except specificity of 16SrRNA/LipL32 qPCR on urine samples was significantly higher (99.6% (99.3%-100%) vs. 92.5% (92.3%-92.8%), p <0.001). Sensitivities of MAT (16% (95% CI 6.3%-29.4%)) and culture (25% (95% CI 13.3%-44.4%)) were low. Mean positive Cq values showed that buffy coat samples were more frequently inhibitory to qPCR than either serum or urine (p <0.001). CONCLUSIONS Serum and urine are better samples for qPCR than buffy coat, and 16SrRNA/LipL32 qPCR performs better than rrs qPCR on urine. Quantitative PCR on admission is a reliable rapid diagnostic tool, performing better than MAT or culture, with significant implications for clinical and epidemiological investigations of this global neglected disease.

Abstract
We developed a novel method, PyroTyping, for discrimination of Mycobacterium tuberculosis isolates combining pyrosequencing and IS6110 polymorphism. A total of 100 isolates were analysed with IS6110-restriction fragment length polymorphism (RFLP), spoligotyping, mycobacterial interspersed repetitive units - variable number tandem repeats (MIRU-VNTR), and PyroTyping. PyroTyping results regarding clustering or discrimination of the isolates were highly concordant with the other typing methods performed. PyroTyping is more rapid than RFLP and presents the same discriminatory power, thus, it may be useful for taking timely decisions for tuberculosis control.

Abstract
Aims The aim of this study was to examine the real time in vivo kinematics of the hip in patients with cam-type femoroacetabular impingement (FAI). Patients and Methods A total of 50 patients (83 hips) underwent 4D dynamic CT scanning of the hip, producing real time osseous models of the pelvis and femur being moved through flexion, adduction, and internal rotation. The location and size of the cam deformity and its relationship to the angle of flexion of the hip and pelvic tilt, and the position of impingement were recorded. Results In these patients with cam-type FAI, there was significant correlation between the alpha angle and flexion to the point of impingement (mean 41.36°; 14.32° to 57.95°) (R = -0.5815 and p = < 0.001). Patients with a large cam deformity (alpha angle > 78°) had significantly less flexion to the point of impingement (mean 36.30°; 14.32° to 55.18°) than patients with a small cam deformity (alpha angle 60° to 78°) (mean 45.34°; 27.25° to 57.95°) (p = < 0.001). Conclusion This study has shown that cam-type impingement can occur early in flexion (40°), particularly in patients with large anterior deformities. These patients risk chondrolabral damage during routine activities such as walking, and going up stairs. These findings offer important insights into the cause of the symptoms, the mechanisms of screening and the forms of treatment available for these patients.

Importance to question sinonasal symptoms and to perform rhinoscopy and rhinomanometry in cystic fibrosis patients. Pediatr Pulmonol 2017; 52:167-174.

Abstract
OBJECTIVES Cystic fibrosis (CF) patients almost regularly reveal sinonasal pathology. The purpose of this study was to assess association between objective and subjective measurements of sinonasal involvement comparing nasal airflow obtained by active anterior rhinomanometry (AAR), nasal endoscopic findings, and symptoms assessed with the Sino-Nasal Outcome Test-20 (SNOT-20). METHODS Nasal cavities were explored by anterior rigid rhinoscopy and findings were compared to inspiratory nasal airflow measured by AAR to quantify nasal patency and subjective health-related quality of life in sinonasal disease obtained with the SNOT-20 questionnaire. Relations to upper and lower airway colonization with Pseudomonas aeruginosa, medical treatment, and sinonasal surgery were analysed. RESULTS A total of 124 CF patients were enrolled (mean age 19.9 ± 10.4 years, range 4-65 years). A significant association of detection of nasal polyposis (NP) in rhinoscopy was found with increased primary nasal symptoms (PNS) which include "nasal obstruction," "sneezing," "runny nose," "thick nasal discharge," and "reduced sense of smell." At the same time patients with pathologically decreased airflow neither showed elevated SNOT-20 scores nor abnormal rhinoscopic findings. Altogether, rhinomanometric and rhinoscopic findings are not significantly related. CONCLUSIONS Among SNOT-20 scores the PNS subscore is related to rhinoscopically detected polyposis and sinonasal secretion. Therefore, we recommend including short questions regarding PNS into CF-routine care. At the same time our results show that a high inspiratory airflow is not associated with a good sensation of nasal patency. Altogether, rhinomanometry is not required within routine CF-care, but it can be interesting as an outcome parameter within clinical trials.

Abstract
In cystic fibrosis (CF) mucociliary clearance of the entire respiratory system is impaired. This allows pathogens, such as Pseudomonas aeruginosa to persist and proliferate, which by progressive pulmonary destruction causes 90 % of premature deaths due to this inherited disease. The dramatic improvement in life expectation of patients due to intensive therapy has resulted in the inevitable but variably expressed sinonasal involvement coming into the clinical and scientific focus. Thereby, almost all CF patients reveal sinonasal pathology and many suffer from chronic rhinosinusitis. Recently, the sinonasal niche has been recognized as a site of initial and persistent colonization by pathogens. This article presents the pathophysiological background of this multiorgan disease as well as general diagnostic and therapeutic standards. The focus of this article is on sinonasal involvement and conservative and surgical options for treatment. Prevention of pathogen acquisition is an essential issue in the otorhinolaryngological treatment of CF patients.

Abstract
The present study was conducted to answer two questions. Firstly, whether or not the use of a mastery-based reading programme led to accelerated progress by an experimental group in contrast to the progress made by a comparison group. Secondly, whether the use of same-age tutoring prejudiced either high or low attainers (as assessed pre-trial). Preand post-test reading test raw scores for experimental and comparison groups were analysed using an independent t-test. The experimental group outperformed the comparison group by a significant margin (p < .005). By contrast an analysis of the scores of the bottom and top half of the experimental group using both the independent t-test and the Wilcoxon Rank Sum Test found no significant differences between the two subgroups in the experimental group. The paper describes the instructional methods used to teach the experimental group, with particular reference to same-age tutoring, and discusses the results in the light of the debate between the proponents of an individualized approach to teaching as opposed to a class-based approach to instruction.

Abstract
OBJECTIVE We previously demonstrated a significant reduction in our incidence of chronic lung disease in our NICU using potentially better practices of avoiding delivery room endotracheal intubation and using early nasal CPAP. We sought to demonstrate whether these improvements were sustained and or improved over time. STUDY DESIGN We conducted a retrospective, cross-sectional analysis of infants 501-1500 grams born at our hospital between 2005 and 2013. Infants born during the 2005-2007, 2008-2010 and 2011-2013 epochs were grouped together, respectively. Descriptive analysis was conducted to determine the number and percent of maternal and neonatal characteristics by year grouping. Chi-squared tests were used to determine whether there were any statistically significant changes in characteristics across year groupings.. Two outcome variables were assessed: a diagnosis of chronic lung disease based on the Vermont Oxford Network definition and being discharged home on supplemental oxygen. RESULTS There was a statistically significant improvement in the incidence of chronic lung disease in infants below 27 weeks' gestation in the three year period in the 2011-2013 cohort compared with those in the 2005-2007 cohort. We also found a statistically significant improvement in the number of infants discharged on home oxygen with birth weights 751-1000 grams and infants with gestational age less than 27 weeks in the 2011-2013 cohort compared to the 2005-2007 cohort. CONCLUSIONS We demonstrated sustained improvement in our incidence of CLD between 2005 and 2013. We speculate that a multifaceted strategy of avoiding intubation and excessive oxygen in the delivery room, the early use of CPAP, as well as the use of volume targeted ventilation, when needed, may help significantly reduce the incidence of CLD.

Abstract
OBJECTIVE The present review systematically examines the integration of language models to improve classifier performance in brain-computer interface (BCI) communication systems. APPROACH The domain of natural language has been studied extensively in linguistics and has been used in the natural language processing field in applications including information extraction, machine translation, and speech recognition. While these methods have been used for years in traditional augmentative and assistive communication devices, information about the output domain has largely been ignored in BCI communication systems. Over the last few years, BCI communication systems have started to leverage this information through the inclusion of language models. MAIN RESULTS Although this movement began only recently, studies have already shown the potential of language integration in BCI communication and it has become a growing field in BCI research. BCI communication systems using language models in their classifiers have progressed down several parallel paths, including: word completion; signal classification; integration of process models; dynamic stopping; unsupervised learning; error correction; and evaluation. SIGNIFICANCE Each of these methods have shown significant progress, but have largely been addressed separately. Combining these methods could use the full potential of language model, yielding further performance improvements. This integration should be a priority as the field works to create a BCI system that meets the needs of the amyotrophic lateral sclerosis population.

Abstract
Abstract
Purpose: Early discontinuation or non-adherence of AI therapy occurs in 25-50 % of patients due to treatment associated toxicities, including musculoskeletal symptoms such as arthralgias and myalgias. The goal of this pilot study is to evaluate the effect of a directed physical therapy regimen including joint mobility and stretching exercises on musculoskeletal symptoms resulting from AI therapy, in comparison to normal physical activity alone.
Patients and methods: Eligibility criteria included post-menopausal women with histological evidence of hormone receptor positive breast cancer who were currently receiving adjuvant AI therapy and experiencing significant joint discomfort/stiffness when attempting activities of daily living which began or significantly increased after initiation of AI therapy. Patients were excluded if they had preexisting rheumatoid arthritis or fibromyalgia, systemic metastasis or ECOG performance status of greater than 2. Patients were randomly assigned to an 8 week directed exercise program under the supervision of a physical therapist (Group A, n=15) or were told to participate in moderate physical activity (walking) (Group B, n=12). Before beginning the study and at the end of the 8 week intervention, patients in both groups underwent a physical therapy evaluation including performance based measures such as functional lower extremity strength and grip strength and a Patient Specific Functional Scale (PSFS) to assess functional ability to complete specific activities. Additionally, all patients answered a series of questionnaires including a pain disability index (PDI), pain scale (PS) and the PHQ4 depression scale. Effects of the directed exercise regimen were evaluated using non-parametric analysis to determine differences between the two groups.
Results: Significant improvement was observed in both left and right grip strength and right pinch in the intervention group (Group A) as compared to the control group (Group B). Additionally, significant improvement in lower body measures including 2-minute step tests and chair raises were observed in patients who underwent the directed exercise program compared to the control group. No significant differences were observed in PS, PDI or PHQ4 between the groups. However, Group A showed a slight improvement on the PS and PDI.
Conclusions: Directed exercise regimens involving joint mobility and stretching exercises may have benefits over moderate physical activity alone for joint pain and arthralgia associated with AI therapy.

Identification of genetic variation exclusive to specific lineages associated with Staphylococcus aureus bacteraemia. J Hosp Infect 2015; 91:136-45.

Abstract
BACKGROUND Meticillin-resistant Staphylococcus aureus (MRSA) bacteraemia cases have declined since 2003, and have mostly been due to two epidemic (E) strains, E15 (multi-locus sequence type clonal complex CC22) and E16 (CC30). By contrast, the incidence of meticillin-susceptible S. aureus (MSSA) bacteraemia has remained largely unchanged and our understanding of these isolates has remained poor. AIM To investigate the distribution and nucleotide sequence of heterogeneous regions between successful lineages using the 2009 British Society for Antimicrobial Chemotherapy (BSAC) Bacteraemia Resistance Surveillance Programme collection of S. aureus. METHODS S. aureus isolates (N = 202) comprised of 103 MRSA and 99 MSSA isolates were analysed using fluorescent amplified fragment length polymorphism (FAFLP) to detect nucleotide variations due to lineage-specific sequence motifs as well as differences in the distribution of mobile genetic elements between lineages. FINDINGS E15 and E16 MRSA strains comprised 79% and 6% of the collection in 2009 respectively. Six lineages, including CC22 and CC30, were associated with MRSA bacteraemia in the UK and Ireland. MSSA isolates were more diverse with 19 different lineages detected. FAFLP revealed lineage-specific sequence variations in loci encoding factors such as proteases or factors involved in haem biosynthesis, both of which may affect the success of major S. aureus lineages. Proteins encoded on certain mobile genetic elements or involved in cobalamin biosynthesis were found to be exclusive to CC8, CC22, or CC30. CONCLUSION Overall, the genetic diversity among regions of the core genome and mobile genetic elements may alter antimicrobial resistance and the production of virulence or fitness factors that may be linked to strain success.
