Abstract
INTRODUCTION Expert consensus operationalized treatment response and remission in obsessive-compulsive disorder (OCD) as a Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) reduction ≥35% and score ≤12 with ≤2 on Clinical Global Impressions Improvement (CGI-I) and Severity (CGI-S) scales, respectively. However, there has been scant empirical evidence supporting these definitions. METHODS We conducted a systematic review and an individual participant data meta-analysis of randomized-controlled trials (RCTs) in adults with OCD to determine optimal Y-BOCS thresholds for response and remission. We estimated pooled sensitivity/specificity for each percent reduction threshold (response) or posttreatment score (remission) to determine response and remission defined by a CGI-I and CGI-S ≤ 2, respectively. RESULTS Individual participant data from 25 of 94 eligible RCTs (1235 participants) were included. The optimal threshold for response was ≥30% Y-BOCS reduction and for remission was ≤15 posttreatment Y-BOCS. However, differences in sensitivity and specificity between the optimal and nearby thresholds for response and remission were small with some uncertainty demonstrated by the confidence ellipses. CONCLUSION While the empirically derived Y-BOCS thresholds in our meta-analysis differ from expert consensus, given the predominance of data from more recent trials of OCD, which involved more refractory participants and novel treatment modalities as opposed to first-line therapies, we recommend the continued use of the consensus definitions.

Abstract
OBJECTIVE Older hospitalized adults with an existing diagnosis of cancer rarely receive cancer treatment after discharge to a skilled nursing facility (SNF). It is unclear to what degree these outcomes may be driven by cumulative effects of previous cancer treatment and their complications vs an absolute functional threshold from which it is not possible to return. We sought to understand post-acute care outcomes of adults newly diagnosed with cancer and explore functional improvement during their SNF stay. DESIGN Retrospective cohort study, 2011-2013. SETTING AND PARTICIPANTS Surveillance, Epidemiology, and End Results - Medicare database of patients with new stage II-IV colorectal, pancreatic, bladder, or lung cancer discharged to SNF. METHODS Primary outcome was time to death after hospital discharge. Covariates include cancer treatment receipt and hospice use. A Minimum Data Set (MDS)-Activities of Daily Living (ADL) score was calculated to measure changes in ADLs during SNF stay. Patient groups of interest were compared descriptively using means and standard deviations for continuous variables and frequencies and percentages for categorical variables. Logistic regression was used to compare patient groups. RESULTS A total of 6791 cases were identified. Forty-six percent of patients did not receive treatment or hospice, 25.0% received no treatment but received hospice, 20.8% received treatment but no hospice, and 8.5% received both treatment and hospice. Only 43% of decedents received hospice. Patients who received treatment but not hospice had the best survival. There were limited improvements in MDS-ADL scores in the subset of patients for whom we have complete data. Those with greater functional improvement had improved survival. CONCLUSIONS AND IMPLICATIONS The majority of patients did not receive future cancer treatment or hospice care prior to death. There was limited improvement in MDS-ADL scores raising concern this population might not benefit from the rehabilitative intent of SNFs.

Abstract
Background and purpose The relevance of metastasis-directed stereotactic body radiation therapy (SBRT) remains to be demonstrated through phase III trials. Multiple SBRT procedures have been published potentially resulting in a disparity of practices. Therefore, the french society of urological radiation oncolgists (GETUG) recognized the need for joint expert consensus guidelines for metastasis-directed SBRT in order to standardize practice in trials carried out by the group. Materials and methods After a comprehensive literature review, 97 recommendation statements were created regarding planning and delivery of spine bone (SBM) and non-spine bone metastases (NSBM) SBRT. These statements were then submitted to a national online two-round modified Delphi survey among main GETUG investigators. Consensus was achieved if a statement received ≥ 75 % agreements, a trend to consensus being defined as 65-74 % agreements. Any statement without consensus at round one was re-submitted in round two. Results Twenty-one out of 29 (72.4%) surveyed experts responded to both rounds. Seventy-five statements achieved consensus at round one leaving 22 statements needing a revote of which 16 achieved consensus and 5 a trend to consensus. The final rate of consensus was 91/97 (93.8%). Statements with no consensus concerned patient selection (3/19), dose and fractionation (1/11), prescription and dose objectives (1/9) and organs at risk delineation (1/15). The voting resulted in the writing of step-by-step consensus guidelines. Conclusion Consensus guidelines for SBM and NSBM SBRT were agreed upon using a validated modified Delphi approach. These guidelines will be used as per-protocole recommendations in ongoing and further GETUG clinical trials.

Abstract
RNA processing, including splicing and alternative polyadenylation, is crucial to gene function and regulation, but methods to detect RNA processing from single-cell RNA sequencing data are limited by reliance on pre-existing annotations, peak calling heuristics, and collapsing measurements by cell type. We introduce ReadZS, an annotation-free statistical approach to identify regulated RNA processing in single cells. ReadZS discovers cell type-specific RNA processing in human lung and conserved, developmentally regulated RNA processing in mammalian spermatogenesis-including global 3' UTR shortening in human spermatogenesis. ReadZS also discovers global 3' UTR lengthening in Arabidopsis development, highlighting the usefulness of this method in under-annotated transcriptomes.

Abstract
An increasing number of researches has been focusing on how design can contribute to happiness by trying to increase wellbeing. The focus is providing solutions through design to improve people's lives, thus increasing the appreciation of their lives. The Ebscohost database was systematically searched for relevant publications about design and wellbeing until 2019. A total of 17 journal articles, published between 2010 and 2018, were included in the research. Data was extracted on macro-theme and category of research, by application area, design, methods, instruments, and focus. Studies on design and wellbeing were explored in the last decade mostly by European researchers. Physical environment, product design, sustainability, and technology are the most common application areas, and most of them have references related to the psychological literature. The main method adopted is experimental and qualitative in nature. The association between design and wellbeing is one that most often targets variables and projects to increase wellbeing instead of discussing how the results will improve positive affect and decrease negative affect to improve people’s lives. The area of research has been growing at a slow steady pace since 2010.

Abstract
Beyond fifth generation (5G) communication systems aim towards data rates in the tera bits per second range, with improved and flexible coverage options, introducing many new technological challenges in the fields of network architecture, signal pro- cessing, and radio frequency front-ends. One option is to move towards cell-free, or distributed massive Multiple-Input Multiple-Output (MIMO) network architectures and highly integrated front-end solutions. This paper presents an outlook on be- yond 5G distributed massive MIMO communication systems, the signal processing, characterisation and simulation challenges, and an overview of the state of the art in millimetre wave antennas and electronics.

Abstract
Background Trichoderma spp. are filamentous fungi causing invasive fungal diseases in patients with haematological malignancies and in peritoneal dialysis patients. Objectives To analyse clinical presentation, predisposing factors, treatment and outcome of Trichoderma infections. Methods A systematic literature review was conducted for published cases of invasive Trichoderma infection in PubMed until December 2021 and by reviewing the included studies’ references. Cases from the FungiScope® registry were added to a combined analysis. Results We identified 50 invasive infections due to Trichoderma species, including 11 in the FungiScope® registry. The main underlying conditions were haematological malignancies in 19 and continuous ambulatory peritoneal dialysis (CAPD) in 10 cases. The most prevalent infection sites were lung (42%) and peritoneum (22%). Systemic antifungal therapy was administered in 42 cases (84%), mostly amphotericin B (n = 27, lipid-based formulation 13/27) and voriconazole in 15 cases (30%). Surgical interventions were performed in 13 cases (26%). Overall mortality was 48% (n = 24) and highest for allogeneic HSCT and solid organ transplantation (SOT) recipients [80% (4/5) and 77% (7/9), respectively]. In patients treated with amphotericin B, voriconazole and caspofungin, mortality was 55% (15/27), 46% (7/15) and 28% (2/7), respectively. Three out of four patients treated with a combination therapy of voriconazole and caspofungin survived. Conclusions Despite treatment with antifungal therapies and surgery, invasive Trichoderma infections are life-threatening complications in immunocompromised patients, especially after HSCT and SOT. In addition, Trichoderma spp. mainly affect the lungs in patients with haematological malignancies and the peritoneum in CAPD patients.

Abstract
PurposeTo evaluate clinicopathologic and treatment characteristics from a population-based cohort of penile cancer, with an emphasis in older adults, due to incomplete evidence to guide therapy in this age subgroup.Materials and MethodsPatients with malignant penile tumors diagnosed 2004-2016 were identified in the Surveillance, Epidemiology and End Results Program (SEER)-18 dataset. Demographic and treatment characteristics were obtained. Population was analyzed by age at diagnosis (<65 vs ≥65 years). We examined univariate associations between age groups with Chi-square analysis. To study survival, we calculated Kaplan-Meier survival curves, but due to the high number of competing events, we also performed a univariate competing risk analysis using the cumulative incidence function, and a multivariate analysis using the Fine-Gray method. We also described competing mortality due to penile cancer and other causes of death.ResultsWe included 3,784 patients. Median age was 68 years, 58.7% were aged ≥65. Older patients were less likely to have received chemotherapy (p<0.001), primary site surgery (p = 0.002), or therapeutic regional surgery (p <0.001). Median overall survival (OS) in patients <65 years was not reached (95% CI incalculable) vs 49 months in those ≥65 years (95% CI 45-53, p <0.0001). On univariate analysis, age was associated with a lower incidence of penile cancer death. On multivariate analysis, stage at diagnosis, and receipt of primary site surgery were associated with a higher incidence of penile cancer death. Estimated penile cancer-specific mortality was higher in patients <65 years in stages II-IV. Estimated mortality due to other causes was higher in older patients across all stages.ConclusionsOlder patients are less likely to receive surgery, chemotherapy and radiotherapy for penile cancer. Primary surgical resection was associated with better penile cancer-specific mortality on multivariate analysis. Competing mortality risks are highly relevant when considering OS in older adults with penile cancer. Factors associated with undertreatment of older patients with penile cancer need to be studied, in order to develop treatment strategies tailored for this population.

Abstract
Purpose Adjuvant chemotherapy reduces recurrence in early-stage triple-negative breast cancer (TNBC). However, data are lacking evaluating anthracycline + taxane (ATAX) versus taxane-based (TAX) chemotherapy in older women with node-negative TNBC, as they are often excluded from trials. The purpose of this study was to evaluate the effect of adjuvant ATAX versus TAX on cancer-specific (CSS) and overall survival (OS) in older patients with node-negative TNBC. Patients and methods Using the SEER-Medicare database, we selected patients aged ≥ 66 years diagnosed with Stage T1-4N0M0 TNBC between 2010 and 2015 (N = 3348). Kaplan–Meier survival curves and adjusted Cox proportional hazards models were used to estimate 3-year OS and CSS. Multivariant Cox regression analysis was used to identify independent factors associated with use of ATAX compared to TAX. Results Approximately half (N = 1679) of patients identified received chemotherapy and of these, 58.6% (N = 984) received TAX, 25.0% (N = 420) received ATAX, and 16.4% (N = 275) received another regimen. Three-year CSS and OS was improved with any adjuvant chemotherapy from 88.9 to 92.2% (p = 0.0018) for CSS and 77.2% to 88.6% for OS (p < 0.0001). In contrast, treatment with ATAX compared to TAX was associated with inferior 3-year CSS and OS. Three-year CSS was 93.7% with TAX compared to 89.8% (p = 0.048) for ATAX and OS was 91.0% for TAX and 86.4% for ATAX (p = 0.032). Conclusion While adjuvant chemotherapy was associated with improved clinical outcomes, the administration of ATAX compared to TAX was associated with inferior 3-year OS and CSS in older women with node-negative TNBC. The use of adjuvant ATAX should be considered carefully in this patient population.

Abstract
In a temperate climate, the mycotoxins deoxynivalenol (DON), nivalenol (NIV), enniatin B (ENN B), mycophenolic acid (MPA), roquefortine C (ROC) and zearalenone (ZEN) are often found in maize silage. Although rumen microbiota are able to degrade some mycotoxins (e.g. DON), others are known to stay mainly intact (e.g. ROC). In addition, mycotoxin degradation can be hampered by a low ruminal pH or decrease in rumen microbial activity. Hence, these mycotoxins can reach the small intestine and exert a cytotoxic effect on intestinal epithelial cells. In this study, a real-time kinetic analysis of the cytotoxicity of these six mycotoxins and some of their metabolites (α- and β-zearalenol, α- and β-ZOL) was performed in a calf small intestinal epithelial cell line (CIEB). Confluency as well as the cell death parameters apoptosis and necrosis were determined to evaluate the mycotoxin-induced cytotoxicity. A combination of Annexin-V green and Cytotox red staining was used to determine early and late apoptosis as well as necrosis. Six different concentrations were tested ranging from 0.78 to 12.5 μM. Compared to cells not exposed to mycotoxins, DON and NIV exert a fast toxic effect with DON being more toxic than NIV within the first hours of incubation, whereas the inverse was observed at 16 h of incubation. On the other hand, MPA and ZEN induced increased Annexin V green positive cells within several hours of incubation with higher toxicity over time. Increased Annexin V green and Cytotox red positive cells were seen for ROC only at the highest concentration tested. For ENN B, increased Annexin V green positive cells were observed only after 12 h and α- and β-ZOL did not show cytotoxic effects. Hence, mycotoxin exposure causes either severe (DON and NIV) or more limited (ZEN, ROC, MPA, and ENN B) risk of bovine intestinal epithelial damage.

Abstract
This paper presents the measurement of the bidirectional reflectance distribution function of tungsten (W) samples and the resulting reflection models in the nuclear fusion device WEST (tokamak). For this, an experimental gonio-spectrophotometer was developed to fully characterize the material's optical and thermal-radiative properties of metallic samples with different roughnesses. Ray-tracing photonic simulation was then carried out to predict the photon behavior in a fully metallic environment as a function of reflectance measurement. Low emissivity (0.1 at 4 μm) and highly specular reflectance (fitting with a Gaussian distribution around the specular direction with a small width lower than 10°) are found for W samples. These measurements have been used as input for the photonic simulation, and the resulting synthetic image reproduced the reflection features well on the upper divertor, detected in WEST infrared experimental images.

Abstract
BACKGROUND The purpose of this study is to evaluate practice patterns and outcomes between intensity-modulated radiation therapy (IMRT) and 3D-conformal radiation (3D-CRT) in early stage glottic cancer. METHODS The linked Surveillance, Epidemiology, and End Results (SEER)-Medicare database was used to identify and compare patient and disease profiles, mortality, and toxicity in patients with T1-2 larynx cancer undergoing definitive radiation (RT). RESULTS A total of 1520 patients underwent definitive radiation with 3D-CRT (n = 1309) or IMRT (n = 211). Non-white race, those with a Charlson Comorbidity Index ≥2, T2 disease, and those treated at community practices were more likely to undergo IMRT. Rates of IMRT increased from 2006 to 2015, while relative rates of 3D-CRT decreased. Two-year CSS was superior with 3D-CRT (hazard ratio [HR], 0.38; 95% confidence interval [CI], 0.22-0.65; p < 0.001). There was no difference in OS between 3D-CRT and IMRT (p = 0.119). CONCLUSIONS Patients receiving 3D-CRT had improved CSS compared to IMRT with no difference in OS.

Abstract
BACKGROUND Omega-3 is a nutritional strategie that have been used to recover muscles from exercise-induced muscle damage in a preventive perspective. AIM To verify whether omega-3 (ω-3) supplementation after a session of resistance exercise facilitates muscle recovery in women undergoing a balanced diet. METHODS This clinical trial was registered under the number NCT02839525. Thirty healthy women (22.2 ± 3.3 years) participated in this double-blinded, placebo-controlled trial. They were randomly distributed into ω-3 (n=15) and placebo (n=15) groups. They ingested ω-3 fish oil (3200 mg/day) or placebo (olive oil) at the dinner after the exercise bout (10 sets of 10 unilateral eccentric contractions in a knee extension chair), as well as at lunch for the three subsequent days. In addition, both groups followed a balanced diet along the four days. Muscle soreness and maximal isometric and isokinetic voluntary contractions were assessed immediately before, and 24, 48, and 72 hours after the resistance exercise. MAIN FINDINGS There was no significant group-time interaction for any outcome. Participants presented increased levels of muscle soreness and reduced muscle strength capacity along the three days after exercise. There was no difference between placebo and ω-3 groups. CONCLUSION Supplementation of ω-3 fish oil for three days after resistance exercise provided no additional benefits compared to placebo supplementation on recovery of healthy young women following a balanced diet.

Abstract
INTRODUCTION Motivational interviewing is an effective style of collaborative communication for the promotion of lifestyle changes in the management of Type 2 diabetes and arterial hypertension. This study evaluates the effectiveness of motivational interviewing in the management of these conditions in primary health care. STUDY DESIGN This study is a double-blind parallel-group RCT performed between June 2018 and July 2019. SETTING/PARTICIPANTS The RCT was conducted in Porto Alegre, Rio Grande do Sul, Brazil, and included individuals with Type 2 diabetes and arterial hypertension. INTERVENTION The participants were randomized to the test/motivational interviewing and usual care groups. The test/motivational interviewing group received the nursing consultation intervention on the basis of motivational interviewing conducted by professionals with 20 hours of training, and the usual-care group received conventional nursing consultation. MAIN OUTCOME MEASURES The main outcome measure was the mean difference in HbA1c. The secondary outcome measures were the mean differences in blood pressure and adherence levels. RESULTS After a mean follow-up of 6 months, 174 participants completed the study (usual-care group=80; test/motivational interviewing group=94). There were statistically significant differences between the groups, with improvement in the test/motivational interviewing group for systolic blood pressure (p<0.01), diastolic blood pressure (p<0.01), and total adherence score as measured by the Martín-Bayarre-Grade questionnaire (p=0.01) and its operational dimensions of treatment adherence and personal involvement (p=0.03, p=0.03). The test/motivational interviewing group showed significantly reduced HbA1c levels (0.4%) at the end of the study (p<0.01). CONCLUSIONS In the context of primary health care, the nursing consultation based on motivational interviewing was shown to be a more effective care strategy than usual care for improving blood pressure levels and adherence levels in individuals with Type 2 diabetes and arterial hypertension. Moreover, motivational interviewing was demonstrated to be useful in reducing HbA1c levels in diabetes management. TRIAL REGISTRATION This study is registered at www.clinicaltrials.gov NCT03729323.

Abstract
Smoking is the main cause of avoidable death and a major public health problem worldwide, with primary healthcare being a strategic setting for treating this problem. Aims: to evaluate the effectiveness of motivational interviewing associated with the cognitive behavioral therapy (CBT) in smoking groups in primary healthcare. A community-based cluster randomized clinical trial was conducted in Brazil, starting in July 2016. Professionals in the test group were trained in motivational interviewing for eight hours to associate it with the CBT. The usual treatment for smoking cessation in groups consists of four structured weekly sessions of 90 minutes each using a CBT. Taylor's linearization was used to correct the p-values; the chi-square test with Pearson correlation was used for categorical variables, and analysis of variance as well as the Student t-test were used for continuous variables. In total, 44 smoking groups were conducted, totaling 329 patients (178 in the motivational interviewing group and 151 in the control group). The smoking cessation rate with motivational interviewing was 61.8%, with RR = 1.25 (95%CI: 1.01-1.54, p = 0.043), and 47.7% in the control group, in the fourth weekly group treatment session. Mean session attendance was 3.1 (95%CI: 2.9-3.3) in the motivational interviewing group and 2.9 (95%CI: 2.5-3.4) in the control group. The completion rate for the motivational interviewing group was 65.2% and for the control group, 57.6%. Motivational interviewing associated with the CBT was shown to be effective and superior to only CBT to smoking cessation in groups in the fourth weekly session and for the population profile of the study (women with an average age of 50.6 years).

Abstract
Secondary osteoarthritis (OA) is a slow progressive, common disorder of synovial joints in dogs. It is characterized by a loss of balance between the synthesis and degeneration of articular cartilage components. Its diagnosis is currently based on the presence of clear radiographic changes, which only occur in the later stages of the disease. Hence, early diagnosis of OA remains a major problem. Therefore, interest in synovial fluid (SF) biomarkers has emerged. Besides pro-inflammatory and degenerative markers, i.e. tumor necrosis factor alpha (TNF-alpha), interleukin-1beta (IL-1beta), tenascin-c (TN-C) and matrix metalloproteinase-2 (MMP-2), metabolic parameters, i.e. pH, glucose and lactate, can potentially be used to detect OA. The current study demonstrated statistically significant differences in the SF levels of pH, glucose and lactate between OA-affected and normal joints. In addition, the in-house validated immuno-assays for TNF-alpha, IL-1beta, TN-C and MMP-2 allowed to demonstrate also statistically significant differences in the SF concentrations for all these biomarkers - except TNF-alpha - between OA-affected and normal joints. However, no correlation was found between any of these biomarkers and the currently used radiographic scoring system for OA in dogs. Future research is warranted to explore the potential of these biomarkers in the early detection of OA and in the severity characterization of this disease.

Abstract
Current liver function tests used in dogs do not consistently normalise after successful surgical attenuation of portosystemic shunts (PSS). Serum hyaluronic acid (sHA) concentrations in dogs with PSS are reported to be higher at diagnosis than in healthy dogs. The objective of this study was to assess sHA as a marker of liver perfusion by measuring sHA concentrations in dogs before and after gradual surgical attenuation of extrahepatic (EH)PSS and by determining whether sHA concentrations could differentiate closed EHPSS from persistent shunting. Specificity of sHA was assessed by comparing sHA concentrations in dogs with EHPSS to those in dogs with other liver diseases. Twenty dogs with EHPSS had sHA concentrations measured at diagnosis, 1, 3, and 6 months postoperatively. In addition, sHA concentrations were determined in 10 dogs with other liver diseases. At EHPSS diagnosis, median sHA concentration was 335.6 ng/mL (43.0-790.7 ng/mL). All dogs had a significant decrease in sHA concentrations from 1 month postoperatively onwards (P < 0.05), regardless of surgical outcome. At all postoperative follow-up visits, there was a significant difference between the median sHA concentration in dogs with closed EHPSS vs. those with persistent shunting (P < 0.05). Median sHA concentration in dogs with other liver diseases was 89.8 ng/mL (22.9-160.0 ng/mL), which was significantly lower than dogs with EHPSS at diagnosis (P < 0.001). In conclusion, sHA is a promising non-invasive biomarker that can help to determine liver perfusion after surgical attenuation of EHPSS. In addition, sHA could potentially be used to differentiate dogs with EHPSS from dogs with other liver diseases.

Abstract
OBJECTIVES This systematic review with meta-analysis was performed to assess whether motivational interviewing (MI) is effective in the prevention of early childhood caries (ECC) and to examine potential sources of heterogeneity. METHODS Interventions based on motivational interviewing were considered eligible. The main outcome was new caries lesions (some studies included white-spot lesions in total count), and secondary outcomes included caregivers' oral health knowledge, home-care behaviours, plaque index, gingival index and fluoride varnish applications. Controls were any type of oral health education or negative controls without any specific intervention. RESULTS From a total of 1498 studies identified in the databases search, 1078 were assessed for eligibility by reading titles and abstracts, after removal of duplicates. Full-text screening was performed in 61 articles, with 18 reporting on 14 different studies included in the qualitative synthesis and 8 in the quantitative synthesis (four studies included new white-spot lesions in total count). Subgroup analysis was performed by the control group dmft/dmfs and the test for subgroup differences suggests that there is a subgroup effect (P = .06), so population caries experience modifies the effect of MI-based intervention. In populations with high caries experience, the MI-based approach proved preventing an average of 3.15 (95% CI: -6.14, -0.17) dmfs in young children. In samples with low caries experience, differences were smaller, since the caries levels were already lower (-0.31; 95% CI: -0.63, 0.00). CONCLUSION Motivational interviewing has the potential to modify knowledge and behaviours and reduce ECC with a more significant impact on children with high caries experience.

Abstract
Abstract
Background
Motivational Interviewing (MI) has been effective in promoting positive changes in various health-related behaviors, including chronic disease management. The main goal of this study was evaluating the effectiveness of this care technology in individual nursing consultations for the control of type 2 Diabetes Mellitus (2DM) and Arterial Hypertension (AH) in primary healthcare.
Methods
Double-blind, controlled, parallel randomized clinical trial conducted in Porto Alegre, Rio Grande do Sul - Brazil, from June 2018 to July 2019. The study subjects suffered from 2DM with associated diagnosis of AH and were randomized individually to the Test/MI Group and Control Group. The Test Group was subjected to an MI-based nursing consultation intervention with a professional who had been trained for 20 hours, while the Control Group received conventional nursing consultation. The variables were collected in order to measure the main glycated hemoglobin and blood pressure outcomes, and for the secondary adherence outcome.
Results
After an average follow-up of 6 months, 175 patients completed the study. There was a significant difference between the groups with improvement in the Test/MI group for the outcomes Systolic Blood Pressure - SBP (p < 0.01), Diastolic Blood Pressure - DBP (p < 0.01), Total Adherence Score in Martín-Bayarre-Grau Questionnaire (p = 0.011) and their dimensions 'Treatment compliance' and 'Personal implication' (p = 0.033; p = 0.031). The blood pressure levels of the patients who received the Motivational Interviewing Intervention showed a significant mean reduction of 15.2 mmHg in SBP and 6.4 mmHg in DBP, compared to the control group. The Test group also showed a significant average intragroup reduction of 0.5% in HbA1c at the completion of the study (p < 0.01).
Conclusions
It is concluded that the MI-based nursing consultation was effective in improving clinical control and adherence in diabetic and hypertensive patients in primary healthcare.
Key messages
MI-based nursing consultation is effective in reducing pressure and glycemic levels in primary healthcare. The MI improves adherence levels in diabetic and hypertensive patients.

Abstract
BACKGROUND Quaternary ammonium compound based disinfectants are commonly used in pig and poultry husbandry to maintain farm hygiene. However, studies have shown that subinhibitory concentrations of these disinfectants may increase antibiotic resistance. Investigation of antibiotic susceptibility is usually assessed via the microbroth dilution method, although this conventional culture-based technique only provides information on the bacteriostatic activity of an antimicrobial agent. Therefore, experiments were performed to investigate the effect of prior benzalkonium chloride (BKC) exposure on the viability of subsequent ciprofloxacin (CIP) treated Escherichia coli. RESULTS Following CIP treatment, bacterial cell counts were significantly higher after exposure to a subinhibitory BKC concentration than without BKC exposure. The flow cytometric results suggested a BKC-dependent onset of membrane damage and loss of membrane potential. CONCLUSION Our results indicate a lower bactericidal effect of CIP treatment on BKC-exposed E. coli isolates compared to unexposed E. coli isolates.

Abstract
e19032 Background: Multiple factors influencing lung cancer prognosis could be used for stratification in randomized intervention trials which are either observer-dependent (performance status) or poorly available (education/comorbidity index). In this study we explored the independence of ER presentation of lung cancer (an objective variable) as a prognostic factor. Methods: We performed a study using patients from the Surveillance, Epidemiology, and End Results-Medicare linked database, aged 66 years or older and diagnosed with lung cancer between 2007 and 2015. ER presentation was defined as ER visit ≤30 days prior to the earliest diagnostic procedure. Factors associated with ER versus non-ER presentation and the impact of ER presentation on overall survival (OS) and Cancer specific survival (CSS) were assessed. Results: Between 2007 and 2015, a total of 75,798 lung cancer patients met study criteria. 37% of small cell lung cancer (SCLC) and 28% non-small cell lung cancer (NSCLC) patients had ER presentation. For both histologies, in univariate Chi-Square analysis ER presentation was affected (p < 0.05) by sex, race, marital status, census tract poverty and education levels, number of comorbidities, geographic region, and cancer stage, but not by age (except with NSCLC) or rural/urban commute. Multivariable Logistic Regression showed that for both histologies, stage IV, Black or Hispanic race/ethnicity, East or mid-West region, ≥2 comorbidities, unmarried, and tract poverty level ≥ median were independent risk factors associated with ER presentation (odds ratio > 1). For NSCLC, year of diagnosis ≥2009, female, age ≥75, South region, tract education level > median; for SCLC, year of diagnosis ≥2012 and age 70-74 were also significantly associated with ER-presentation. ER versus non-ER presentation was associated with lower 1-yr OS in NSCLC (43% vs 61% HR 1.79, 95% CI 1.68, 1.77; p < 0.0001) and SCLC (33% vs 43% HR 1.32, 95% CI 1.25, 1.40; p < 0.0001). After adjusting for histology, year of diagnosis, age, sex, race, marital status, region, poverty level, education level, number of comorbidities, and stage in a multivariable Cox model, ER presentation remained an independent poor prognostic marker (HR for OS 1.34, 95% CI 1.31, 1.37; p < 0.0001; HR for CSS 1.32, 95% CI 1.29, 1.36; p < 0.0001). Conclusions: ER presentation of lung cancer is an independent, objective, highly practical poor prognostic risk factor which should be considered for patient stratification and data analyses within interventional clinical trials.

Abstract
e12505 Background: TNBC is an aggressive breast cancer subtype comprising approximately 15% of breast cancers. Adjuvant chemotherapy reduces the risk of recurrence, particularly in patients with tumors > 1 cm or node positive disease. Anthracycline (A) + taxane (T)-containing regimens are more efficacious than T-based regimens, however, the risk of cardiac toxicity is greater in older patients. We investigated the use of AT and T-containing regimens in patients ≥ 66 years old with node negative TNBC and evaluated clinical outcomes and cardiac risk factors. Methods: We identified female patients ≥ 66 diagnosed between 2010-2015 with TNBC node negative disease in the Surveillance, Epidemiology, and End Results (SEER) Medicare database. Baseline characteristics, including age, tumor size, cardiac history, and adjuvant chemotherapy administration (AT vs. T) were collected. A logistic regression analysis was performed to estimate independent predictors of AT vs. T chemotherapy. Overall survival (OS) was estimated at 3 years. Results: We identified 3348 patients, including 1679 (50.2%) who received chemotherapy for T1a/bN0 (32.5%), T1cN0 (55.5%), T2N0 (57.0%) and T3/T4N0 (49.6%) disease. Of those, 984 (58.6%) received T, 420 (25.0%) received AT and 275 (16.4%) received other chemotherapy. AT use was associated with larger tumor size; T1a/bN0 (13.6%), T1cN0 (21.3%), T2N0 (31.6%) and T3/T4N0 (34.9%). In a multivariate analysis, independent predictors of AT vs. T were age, region treated in the USA, tumor size and presence of prior cardiac risk factors or pre-existing cardiac disease. OS at 3 years was 91% for T and 86% for AT (p 0.03). Conclusions: Approximately half of older patients diagnosed with node negative TNBC received adjuvant chemotherapy. T-based regimens were more commonly used than AT regimens. Younger age, higher stage and lack of cardiac comorbidities correlated with use of AT compared to T. Continued investigation of the benefit of adjuvant chemotherapy in older patients may assist in clinical decision making.

Abstract
BACKGROUND Disinfectants are frequently used in animal production to reduce or eliminate the load of infectious agents and parasites in buildings and equipment associated with the housing or transportation of animals. There are growing concerns that the use of disinfectants would select for resistance to antibiotics and disinfectants. The aim of this study was to determine the effect of repeated use of different disinfectants on the disinfectant and antibiotic susceptibility under practical conditions in a broiler and pig pilot farm. Therefore, the susceptibility of Escherichia coli (E. coli) to 14 antibiotics and 4 disinfectants was monitored over a one-year period. RESULTS High (20-50%) to very high (> 50%) resistance levels for ampicillin, sulfamethoxazole, trimethoprim and tetracycline were observed in both animal production types. Disinfectant susceptibility did not change over time and did not depend on the used disinfection product. Compared to in-use concentrations of formaldehyde, benzalkoniumchloride and a peracetic acid - hydrogen peroxide formulation, all E. coli strains remained susceptible indicating that the use of disinfectants did not select for disinfectant resistance. Moreover, no association could be found between the use of disinfectants and antibiotic resistance. CONCLUSIONS These findings suggest that repeated use of disinfectants in agricultural environments does not select for antibiotic resistance nor does it reduce disinfectant susceptibility.

Abstract
Dogs with babesiosis can present with multiple complications, including acute kidney injury (AKI). The objective of this study was to characterize AKI in dogs with babesiosis caused by Babesia rossi at presentation and after treatment. Thirty-five client-owned dogs with B. rossi infection and 10 control dogs were included in this prospective observational study. Blood and urine were collected in Babesia-infected dogs at presentation (T0, n = 35), after 24 h (T24h, n = 11), and after 1 month (T1m, n = 9). The following urinary kidney injury biomarkers were assessed: urinary protein to creatinine ratio (UPC), urinary glomerular injury biomarkers (immunoglobulin G (uIgG) and C-reactive protein (uCRP)), and urinary tubular injury biomarkers (retinol-binding protein (uRBP) and neutrophil gelatinase-associated lipocalin (uNGAL)). Serum functional renal biomarkers were creatinine (sCr) and symmetric dimethylarginine (sSDMA). Post-mortem kidney biopsies were analyzed by light and transmission electron microscopy. At T0, all kidney injury biomarkers were significantly higher in Babesia-infected dogs compared to healthy controls (P < 0.001), while functional renal biomarkers were not significantly different (P > 0.05). At T24h, all urinary tubular injury biomarkers and UPC decreased significantly (P < 0.01), while glomerular injury biomarkers did not (P = 0.084). At T1m, all urinary kidney injury biomarkers decreased to values not significantly different from healthy controls (P > 0.5). Significant changes in functional renal biomarkers were not seen after treatment (P > 0.05). Dogs with complicated babesiosis had significantly higher glomerular injury biomarkers, UPC, and sSDMA compared to uncomplicated cases (P < 0.05), while all tubular injury biomarkers and sCr were not significantly different (P > 0.1). Dogs with babesiosis caused by B. rossi showed transient kidney injury, which was detected by all kidney injury biomarkers, but remained undetected by functional biomarkers. All infected dogs, irrespective of disease severity, suffered comparable kidney injury based on tubular injury biomarker concentrations, while loss of function was seen more often in dogs with complicated babesiosis based on sSDMA results.

Abstract
High ambient temperature induces an increase in bovine body temperature above the physiological homeothermic point, leading to impaired reproductive performance. Belgian Blue bulls are more susceptible to heat stress compared with most other cattle breeds. Therefore, the aim of this study was to investigate whether high ambient temperature affected bull semen quality and subsequent embryo development. For this purpose, semen samples were collected from six Belgian Blue bulls during August (14-28 days after three consecutive warm days with temperature-humidity index between 63.8 and 83.7) and March 2016 (temperature-humidity index between 35.9 and 47.4). After semen collection, volume, sperm concentration, and motility of fresh semen were assessed. Furthermore, frozen sperm samples were used to assess the motion parameters and morphological abnormalities using computer-assisted sperm analysis, viability and reactive oxygen species (hydrogen peroxide and superoxide) production using flow cytometry, and acrosome integrity and chromatin condensation using fluorescence microscopy. Afterward, blastocysts were produced (r=4) by conventional invitro methods for assessment of embryo development (Wydooghe et al. 2014 Reprod. Fertil. Dev. 26, 717-724; https://doi.org/10.1071/RD13043). Cleavage rate was determined 48h after fertilisation, and the blastocyst rates were determined on Days 7 and 8 postinsemination. Moreover, Day 8 blastocysts underwent differential staining in order to determine the numbers of the inner cell mass, trophectoderm, total cell number, and apoptotic cells ratio. The data set was analysed using the GLM procedure of SAS (SAS Institute Inc.). Normal distribution was checked using the UNIVARIATE procedure, and the Shapiro-Wilk test and arcsine square root transformation were used when required. Furthermore, Duncan's test was applied to determine the significant differences (P=0.05). In fresh semen, samples from the non-heat-stressed (NHS) group showed a higher sperm concentration compared with samples from the heat-stressed (HS) group (P=0.05), whereas semen volume and motility were not affected by heat stress (P>0.05). In frozen-thawed semen, total and progressive motility and straight-line velocity were lower in the HS group compared with the NHS group (P=0.05), whereas the generation of H2O2, percentages of aberrant chromatin condensation, total morphological abnormality, spermatozoa with bent tails, and distal protoplasmic droplets were higher in the HS group compared with the NHS group (P=0.05). The cleavage rate and blastocyst rates on Days 7 and 8 were higher (P=0.05) in the NHS group (70.4±1.13, 25.4±1.84, and 40.3±1.15, respectively) compared with the HS group (62.8±1.49, 15.4±1.56, and 23.3±1.84, respectively). However, there were no significant differences in hatched or hatching rate of two treatments (P>0.05). The total cell number and trophectoderm were higher in NHS-derived blastocysts than in HS-derived blastocysts (P=0.05), whereas the apoptotic cells ratio was lower (P<0.001) in NHS blastocysts (2.16±0.48% vs. 5.21±0.52%). In conclusion, these findings show that elevated ambient temperature during summer as a consequence of climate change can lead to decreased quality of fresh and frozen-thawed bull spermatozoa and subsequent embryo development.

Abstract
BACKGROUND Studies show significant alterations in insular cortical thickness in patients with somatoform pain disorder (SPD). Additionally, associations between childhood maltreatment and morphometric alterations in insular cortex have been observed. Since patients with SPD often report about adverse childhood experiences, we were interested in the interrelationship of exposure to childhood maltreatment and insular cortical thickness in patients with SPD. METHODS Fifteen adult patients with SPD (ICD-10 F 45.40/41, DSM-Code 307.80) and thirteen healthy adult controls underwent T1-weighted MR brain imaging. In the voxel-based morphometry (VBM) analysis we compared whole brain cortical thickness between patients and controls using a Student's two-sampled t-test (p < .05). Then we performed a secondary analysis to detect differences in cortical thickness levels in the insular cortex between both groups. For further analysis of differences in insular cortical thickness we used gender, age, depressive symptoms [Patient Health Questionnaire (PHQ)-9], and whole brain cortical thickness as nuisance covariates. Subsequently we explored associations between insular cortical thickness, symptom severity (PHQ-15) and past experiences of childhood maltreatment (CTQ) in both groups. RESULTS Patients showed reduced insular cortical thickness in a subregion of right Brodmann area (BA) 13 (anterior part of the insular cortex), whereas whole brain cortical thickness did not differ between groups. The between-group difference in the identified insular subregion of right BA 13 was not diminished by any of the covariates. This implies that the reduction in cortical thickness in the identified insular subregion might be due to a specific group effect. The effect sizes indicate that the group of patients experienced more childhood maltreatment than the control group. Nonetheless, significant correlations of insular cortical thickness with symptom severity and childhood maltreatment in the total collective could not be demonstrated for the group of patients. CONCLUSIONS Our data suggest that alterations in the identified insular subregion of right BA 13 are associated with somatoform pain, independent of gender, age, or coincident depression levels. To identify significant associations of insular cortical thickness and experiences of childhood maltreatment in patients with SPD investigations within larger samples are highly recommended.

Abstract
Background Ear irrigation is a commonly used method for removing earwax in general
practice. There is no firm evidence if no pre-treatment is as good as
pre-treatment with various standard preparations. Aim To assess the effectiveness of no pre-treatment compared to pre-treatment
with commercially available cerumenolytics and to assess which preparation
is best suited for pre-treatment. Methods This is a pragmatic observational study of patients with cerumen treated from
a single GP with 3 different preparations or no preparation prior to
standardized ear irrigation. Generalized linear mixed models with logit link
function were performed to assess the effectiveness of pre-treatment with
different preparations and no pre-treatment. The models were adjusted for
age group (<70, ≥70) and sex. Results A total of 168 patients (298 ears, 58 % female, median age 65 years)
consulted for obstructive cerumen, some of them several times. The cerumen
was successfully removed in 70% (208/298). Comparing any preparation to no
preparation (aggregated comparison), the odds ratio for complete clearance
was 1.35 (95%confidence interval: 0.69-2.65). Comparing the preparations
individually, the odds ratio of the docusate-sodium-based preparation was
1.87 (95% CI: 0.79-4.42) indicating a higher effectiveness. Although, not
statistically significant. Ear irrigation was less successful for patients
aged ≥ 70 years (OR = 0.48, 95% CI: 0.23-0.98). Conclusions The aggregated comparison indicates a slight trend toward a higher
effectiveness of any pre-treatment compared to no pre-treatment. The
effect-size of docusate-sodium-based pre-treatment indicates a higher
effectiveness of cerumen impaction removal. Nevertheless, superiority could
not be shown conclusively according to the statistical significance given
the restricted sample size.

Abstract
Joule energy loss due to resistive heating is omnipresent in today's electronic devices whereas quantum-mechanical dissipation is largely unexplored. Here, we experimentally observe a suppression of the Joule dissipation in Bi2Te3 due to topologically protected surface states. Instead, a different type of dissipation mechanism is observed by pendulum atomic force microscopy, which is related to single-electron tunnelling resonances into image potential states that are slightly above the Bi2Te3 surface. The application of a magnetic field leads to the breakdown of the topological protection of the surface states and restores the expected Joule dissipation process. Nanomechanical energy dissipation experienced by the cantilever of the pendulum atomic force microscope provides a rich source of information on the dissipative nature of the quantum-tunnelling phenomena on the topological insulator surface, with implications for coupling a mechanical oscillator to the generic quantum material.

Abstract
Friction force at the nanoscale, as measured from the lateral deflection of the tip of an atomic force microscope, usually shows a regular stick-slip behavior superimposed by a stochastic part (fluctuations). Previous studies showed the overall fluctuations to be correlated and multi-fractal, and thus not describable simply by e.g. a white noise. In the present study, we investigate whether one can extract an equation to describe nano-friction fluctuations directly from experimental data. Analysing the raw data acquired by a silicon tip scanning the NaCl(001) surface (of lattice constant 5.6 Å) at room temperature and in ultra-high vacuum, we found that the fluctuations possess a Markovian behavior for length scales greater than 0.7 Å. Above this characteristic length, the Kramers-Moyal approach applies. However, the fourth-order KM coefficient turns out to be negligible compared to the second order coefficients, such that the KM expansion reduces to the Langevin equation. The drift and diffusion terms of the Langevin equation show linear and quadratic trends with respect to the fluctuations, respectively. The slope 0.61 ± 0.02 of the drift term, being identical to the Hurst exponent, expresses a degree of correlation among the fluctuations. Moreover, the quadratic trend in the diffusion term causes the scaling exponents to become nonlinear, which indicates multifractality in the fluctuations. These findings propose the practical way to correct the prior models that consider the fluctuations as a white noise.

Abstract
Resistance to antibiotics threatens to become a worldwide health problem. An important attributing phenomenon in this context is that pathogens can acquire antibiotic resistance genes through conjugative transfer of plasmids. To prevent bacterial infections in agricultural settings, the use of veterinary hygiene products, such as disinfectants, has gained popularity and questions have been raised about their contribution to such spreading of antibiotic resistance. Therefore, this study investigated the effect of subinhibitory concentrations of benzalkoniumchloride (BKC), a quaternary ammonium compound (QAC), on the conjugative transfer of antibiotic resistance genes. Five Escherichia coli field strains originating from broiler chickens and with known transferable plasmid-mediated ciprofloxacin resistance were exposed to subinhibitory BKC concentrations: 1/3, 1/10 and 1/30 of the minimum bactericidal concentration. Antibiotic resistance transfer was assessed by liquid mating for 4 h at 25°C using E. coli K12 MG1655 as recipient strain. The transfer ratio was calculated as the number of transconjugants divided by the number of recipients. Without exposure to BKC, the strains showed a ciprofloxacin resistance transfer ratio ranging from 10-4 to 10-7. No significant effect of exposure to subinhibitory concentrations of BKC was observed on this transfer ratio.

Abstract
Motivational interviewing (MI) is an approach that uses dialogue about behavioral change to encourage a constructive relationship between professionals and patients. The aim of this study was to evaluate the maintenance of basic MI skills in the daily practice of dentists and oral health technicians (OHTs) after a training course and for two years of follow-up in the context of primary health care (PHC). A randomized community trial, from September 2012 to September 2014, was conducted at the Community Health Service of Conceição Hospital Group in Porto Alegre, RS, Brazil. The experimental group consisted of all 41 dentists and OHTs who received an intensive eight-hour training course in basic MI principles; the control group consisted of 31 dentists and OHTs who did not receive MI training. The follow-up assessments were at one and two years using three instruments validated for MI. In the one- and two-year follow-ups, improvement was maintained in responses with a statistically significant difference for use of open questioning, reflective listening, and total percentage of correct answers (p<0.001), with a large effect size (ES=1.12). On the Helpful Responses Questionnaire, the participants continued using open questioning and reflective listening (p<0.001), maintaining an increase in the percentage of responses compatible with MI (p<0.001). Likewise, the effect size remained large (ES=1.33) over time. These results suggest that the training course with dentists and OHTs of the PHC oral health staff was effective over the two-year follow-up in enabling them to act in the spirit and techniques of MI.

Abstract
BACKGROUND The project entitled Surveillance of Antibiotic Use and Resistance in Intensive Care Units (SARI) was initiated in Germany in 2000. In this article, we describe developments in antibiotic use and resistance rates in the participating intensive care units over the years 2001-2015. METHODS The intensive care units supplied monthly figures on patient days, antibiotic use (in defined daily doses, DDD), and resistance data for 13 pathogens. The density of antibiotic use per 1000 patient days was calculated on the basis of antibiotic use, DDD, and patient days, and the resistance density per 1000 patient days was calculated from the number of resistant pathogens. RESULTS In the years 2001-2015, data on 2 920 068 patient days were collected in 77 intensive care units. The average overall antibiotic use rose by 19% over this period, with a marked increase in the density of carbapenem use (from 76 to 250 DDD per 1000 patient days, +230%) and piperacillin-tazobactam use (from 42 to 146 DDD per 1000 patient days, +247%). The proportion of Escherichia coli and Klebsiella pneumoniae isolates that were resistant to third-generation cephalosporins increased markedly initially, then remained stable over the remainder of the observation period. The proportion of methicillin-resistant Staphylococcus aureus was stable over the entire period. The rates of vancomycin resistance among Enterococcus faecium isolates and imipenem resistance among gram-negative pathogens increased from 2.3% to 13.3% and from 0.1% to 0.3%, respectively. CONCLUSION The resistance density of gram-negative multiresistant pathogens in the participating intensive care units increased markedly. The rise in imipenem-resistant pathogens arouses particular concern. The increased use of broad-spectrum/reserve antibiotics may well have contributed to this development. Efforts to use antibiotics rationally, e.g., with the support of multidisciplinary "antibiotic stewardship" teams, are therefore vitally important. As participation in SARI is voluntary, these surveillance data cannot be considered representative of Germany as a whole.

Abstract
OBJECTIVES To describe the spectrum of movement disorders and cerebrospinal fluid (CSF) neurotransmitter profiles in paediatric patients with POLG disease. METHODS We identified children with genetically confirmed POLG disease, in whom CSF neurotransmitter analysis had been undertaken. Clinical data were collected retrospectively. CSF neurotransmitter levels were compared to both standardised age-related reference ranges and to non-POLG patients presenting with status epilepticus. RESULTS Forty-one patients with POLG disease were identified. Almost 50% of the patients had documented evidence of a movement disorder, including non-epileptic myoclonus, choreoathetosis and ataxia. CSF neurotransmitter analysis was undertaken in 15 cases and abnormalities were seen in the majority (87%) of cases tested. In many patients, distinctive patterns were evident, including raised neopterin, homovanillic acid and 5-hydroxyindoleacetic acid levels. CONCLUSIONS Children with POLG mutations can manifest with a wide spectrum of abnormal movements, which are often prominent features of the clinical syndrome. Underlying pathophysiology is probably multifactorial, and aberrant monoamine metabolism is likely to play a role.
