Abstract
Importance Patients with relapsed small cell lung cancer (SCLC), a high replication stress tumor, have poor prognoses and few therapeutic options. A phase 2 study showed antitumor activity with the addition of the ataxia telangiectasia and Rad3-related kinase inhibitor berzosertib to topotecan. Objective To investigate whether the addition of berzosertib to topotecan improves clinical outcomes for patients with relapsed SCLC. Design, Setting, and Participants Between December 1, 2019, and December 31, 2022, this open-label phase 2 randomized clinical trial recruited 60 patients with SCLC and relapse after 1 or more prior therapies from 16 US cancer centers. Patients previously treated with topotecan were not eligible. Interventions Eligible patients were randomly assigned to receive topotecan alone (group 1), 1.25 mg/m2 intravenously on days 1 through 5, or with berzosertib (group 2), 210 mg/m2 intravenously on days 2 and 5, in 21-day cycles. Randomization was stratified by tumor sensitivity to first-line platinum-based chemotherapy. Main Outcomes and Measures The primary end point was progression-free survival (PFS) in the intention-to-treat population. Secondary end points included overall survival (OS) in the overall population and among patients with platinum-sensitive or platinum-resistant tumors. The PFS and OS for each treatment group were estimated using the Kaplan-Meier method. The log-rank test was used to compare PFS and OS between the 2 groups, and Cox proportional hazards models were used to estimate the treatment hazard ratios (HRs) and the corresponding 2-sided 95% CI. Results Of 60 patients (median [range] age, 59 [34-79] years; 33 [55%] male) included in this study, 20 were randomly assigned to receive topotecan alone and 40 to receive a combination of topotecan with berzosertib. After a median (IQR) follow-up of 21.3 (18.1-28.3) months, there was no difference in PFS between the 2 groups (median, 3.0 [95% CI, 1.2-5.1] months for group 1 vs 3.9 [95% CI, 2.8-4.6] months for group 2; HR, 0.80 [95% CI, 0.46-1.41]; P = .44). Overall survival was significantly longer with the combination therapy (5.4 [95% CI, 3.2-6.8] months vs 8.9 [95% CI, 4.8-11.4] months; HR, 0.53 [95% CI, 0.29-0.96], P = .03). Adverse event profiles were similar between the 2 groups (eg, grade 3 or 4 thrombocytopenia, 11 of 20 [55%] vs 20 of 40 [50%], and any grade nausea, 9 of 20 [45%] vs 14 of 40 [35%]). Conclusions and Relevance In this randomized clinical trial, treatment with berzosertib plus topotecan did not improve PFS compared with topotecan therapy alone among patients with relapsed SCLC. However, the combination treatment significantly improved OS. Trial Registration ClinicalTrials.gov Identifier: NCT03896503.

Abstract
Small-cell lung cancer (SCLC) is the most lethal type of lung cancer. Specifically, MYC-driven non-neuroendocrine SCLC is particularly resistant to standard therapies. Lurbinectedin was recently approved for the treatment of relapsed SCLC, but combinatorial approaches are needed to increase the depth and duration of responses to lurbinectedin. Using high-throughput screens, we found inhibitors of ataxia telangiectasia mutated and rad3 related (ATR) as the most effective agents for augmenting lurbinectedin efficacy. First-in-class ATR inhibitor berzosertib synergized with lurbinectedin in multiple SCLC cell lines, organoid, and in vivo models. Mechanistically, ATR inhibition abrogated S-phase arrest induced by lurbinectedin and forced cell cycle progression causing mitotic catastrophe and cell death. High CDKN1A/p21 expression was associated with decreased synergy due to G1 arrest, while increased levels of ERCC5/XPG were predictive of increased combination efficacy. Importantly, MYC-driven non-neuroendocrine tumors which are resistant to first-line therapies show reduced CDKN1A/p21 expression and increased ERCC5/XPG indicating they are primed for response to lurbinectedin-berzosertib combination. The combination is being assessed in a clinical trial NCT04802174.

Abstract
Acute myeloid leukemia (AML) is a cancer of myeloid-lineage cells with limited therapeutic options. We previously combined ex vivo drug sensitivity with genomic, transcriptomic, and clinical annotations for a large cohort of AML patients, which facilitated discovery of functional genomic correlates. Here, we present a dataset that has been harmonized with our initial report to yield a cumulative cohort of 805 patients (942 specimens). We show strong cross-cohort concordance and identify features of drug response. Further, deconvoluting transcriptomic data shows that drug sensitivity is governed broadly by AML cell differentiation state, sometimes conditionally affecting other correlates of response. Finally, modeling of clinical outcome reveals a single gene, PEAR1, to be among the strongest predictors of patient survival, especially for young patients. Collectively, this report expands a large functional genomic resource, offers avenues for mechanistic exploration and drug development, and reveals tools for predicting outcome in AML.

Abstract
Metastatic urothelial carcinoma (UC) carries a poor prognosis and a 5-year overall survival of less than 5%, despite standard of care therapy using cisplatin-based chemotherapy and immune checkpoint inhibitors. Thus, novel agents that improve survival and have an acceptable toxicity profile are urgently needed. Antibody-drug conjugates (ADCs) represent a promising new treatment option that utilizes the targeting ability of an antibody to deliver cytotoxic drugs directly to tumors. Many ADCs are currently being investigated for treatment of UC, with enfortumab vedotin being recently approved by the US Food and Drug Administration for treatment of metastatic UC with progressive disease after chemotherapy and/or immune checkpoint inhibitors. Overall, ADCs hold promise as a long-awaited treatment option for UC.

Abstract
The implementation of targeted therapies for acute myeloid leukaemia (AML) has been challenging because of the complex mutational patterns within and across patients as well as a dearth of pharmacologic agents for most mutational events. Here we report initial findings from the Beat AML programme on a cohort of 672 tumour specimens collected from 562 patients. We assessed these specimens using whole-exome sequencing, RNA sequencing and analyses of ex vivo drug sensitivity. Our data reveal mutational events that have not previously been detected in AML. We show that the response to drugs is associated with mutational status, including instances of drug sensitivity that are specific to combinatorial mutational events. Integration with RNA sequencing also revealed gene expression signatures, which predict a role for specific gene networks in the drug response. Collectively, we have generated a dataset-accessible through the Beat AML data viewer (Vizome)-that can be leveraged to address clinical, genomic, transcriptomic and functional analyses of the biology of AML.

Abstract
BackgroundPatients with first-episode psychosis comprise a high-risk group in terms of suicide.AimsTo identify predictive factors for suicidal behaviour and to examine the effect of integrated treatment on suicidal behaviour and hopelessness.MethodA total of 341 patients with a first-episode schizophrenia-spectrum disorder were randomised to integrated treatment or treatment as usual.ResultsDuring the 1-year follow-up period, 11% attempted suicide. This was associated with female gender, hopelessness, hallucinations and suicide attempt reported at baseline, with the two latter variables being the only significant ones in the final multivariate model. The integrated treatment reduced hopelessness.ConclusionsHallucinations and suicide attempt before inclusion in the study were the most significant predictors of suicide attempt in the follow-up period.

Abstract
BACKGROUND Proteinase-activated receptor 2 (PAR2 ) is a G protein-coupled receptor activated by trypsin-like serine proteinases. PAR2 activation has been associated with inflammation including allergic airway inflammation. We have also shown that PAR2 activation in the airways leads to allergic sensitization. The exact contribution of PAR2 in the development of eosinophilic inflammation and airway hyperresponsiveness (AHR) in sensitized individuals is not clear. OBJECTIVE To investigate whether functional inhibition of PAR2 during allergen challenge of allergic mice would inhibit allergen-induced AHR and inflammation in mouse models of asthma. METHODS Mice were sensitized and challenged with ovalbumin (OVA) or cockroach extract (CE). To investigate the role of PAR2 in the development of AHR and airway inflammation, we administered blocking anti-PAR2 antibodies, or a cell permeable peptide inhibitor of PAR2 signalling, pepducin, i.n. before allergen challenges and then assessed AHR and airway inflammation. RESULTS Administration of anti-PAR2 antibodies significantly inhibited OVA- and CE-induced AHR and airway inflammation. In particular, two anti-PAR2 antibodies, the monoclonal SAM-11 and polyclonal B5, inhibited AHR, airway eosinophilia, the increase of cytokines in the lung tissue and antigen-specific T cell proliferation, but had no effect on antigen-specific IgG and IgE levels. Pepducin was also effective in inhibiting AHR and airway inflammation in an OVA model of allergic airway inflammation. CONCLUSIONS AND CLINICAL RELEVANCE Functional blockade of PAR2 in the airways during allergen challenge improves allergen-induced AHR and inflammation in mice. Therefore, topical PAR2 blockade in the airways, through anti-PAR2 antibodies or molecules that interrupt PAR2 signalling, has the potential to be used as a therapeutic option in allergic asthma.

Abstract
INTRODUCTION High-intensity focused ultrasound (HIFU) is an ablative treatment undergoing assessment for the treatment of benign and malignant disease. We describe the first reported intracavitary HIFU ablation for recurrent, unresectable and symptomatic cervical cancer. CASE DESCRIPTION A 38 year old woman receiving palliative chemotherapy for metastatic cervical adenocarcinoma was offered ablative treatment from an intracavitary trans-rectal HIFU device (Sonablate® 500). Pre-treatment symptoms included vaginal bleeding and discharge that were sufficient to impede her quality of life. No peri-procedural adverse events occurred. Symptoms resolved completely immediately post-procedure, reappeared at 7 days, increasing to pre-procedural levels by day 30. DISCUSSION AND EVALUATION This first time experience of intracavitary cervical HIFU suggests that it is feasible for palliation of advanced cervical cancer, with no early evidence of unexpected toxicity. Ethical approval had also been granted for the use of per-vaginal access if appropriate. This route, alone or in combination with the rectal route, may provide increased accessibility in future patients with a redesigned device more suited to trans-vaginal ablations. CONCLUSION Intracavitary HIFU is a potentially safe procedure for the treatment of cervical cancer and able to provide symptomatic improvement in the palliative setting.

Abstract
Abstract
We have recently discovered that a large percentage (59%) of patients with chronic neutrophilic leukemia (CNL) or atypical chronic myeloid leukemia (aCML) have mutations in Colony Stimulating Factor 3 Receptor (CSF3R, aka GCSFR) (Maxson et al, NEJM 2013). These mutations are either point mutations in the extracellular domain (T618I, T615A) or truncations of the cytoplasmic domain. The most frequent mutation is T618I (aka T595I). The two classes of CSF3R mutations operate through distinct mechanisms that result in differential sensitivity to inhibition of tyrosine kinases downstream of CSF3R. While the mechanism of action of CSF3R truncation mutations has been well characterized-they have increased cell surface expression due to loss of negative regulatory motifs-the way in which the CSF3R point mutations activate the receptor is unclear.
Consistent with a previous report, the CSF3R T618I mutation is ligand independent in both mouse bone marrow colony assays and the Ba/F3 pro-B cell line. WT CSF3R consists of two molecular weight species suggestive of differential posttranslational modification. Analysis of CSF3R point mutations T618I and T615A revealed an alteration of banding pattern of these mutations. Since extracellular threonine residues are capable of being O-glycosylated, we employed endoglycosidase digestion to reveal that the larger CSF3R species is O-glycosylated. Furthermore the T618I and T615A mutations reduce O-glycosylation of the receptor. This analysis was confirmed by direct labeling of O-glycosylation using azide-modified galactosamine, which labeled WT CSF3R, but had minimal labeling of CSF3R T618I. Receptor dimerization studies showed increased dimerization of the CSF3R T618I mutant relative to WT.
Sequencing of CSF3R from an atypical CML patient samples revealed an additional mutation not previously observed in this disease, T640N. The T640N mutation (aka T617N) is a ligand-independent mutation originally found in a family with hereditary chronic neutrophilia (Plo et al, JEM 2009). Plo et al found that this mutation resides within the transmembrane domain and predicted by molecular modeling that it increased receptor dimerization through interaction of the transmembrane helices. In mouse bone marrow colony assays we confirmed the ligand-independence of the mutation and also found that it had similar potency as T618I in colony and cytokine-independent growth assays. Furthermore, like T618I, the T640N mutation conferred sensitivity to a JAK kinase inhibitor in colony assays. Surprisingly, the T640N mutation had an alteration of banding pattern very similar to T618I, suggesting that it may also have altered glycosylation status, even though the mutation resides within the transmembrane domain. Our studies demonstrate that O-glycosylation is critical for regulation of CSF3R dimerization and that the T618I and T640N mutations can activate the receptor to promote oncogenesis.

Abstract
OBJECTIVE To investigate the antimicrobial activity of SAP-containing wound dressings in vitro over a prolonged period of time (7 days) and to assess their ability to sustain the antimicrobial effect. METHOD SAP dressings were tested according to the JIS L 1902:2002 against the pathogens Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli and Candida albicans.Additionally, effect on S. aureus and P. aeruginosa growth was investigated after a prolonged incubation period of 7 days. Furthermore, both SAP dressings were repeatedly inoculated with P. aeruginosa suspension and, after 7 days, microbial growth under the dressings was evaluated. RESULTS Both SAP-containing wound dressings tested exhibited a significant to strong antimicrobial activity against Staphylococcus aureus, MRSA, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, and Candida albicans in vitro. Moreover, it could be shown that they were able to sustain antibacterial efficacy over a prolonged period of time. Using a direct incubation method with repeated re-inoculation of the dressing samples, it could be shown that growth of P. aeruginosa was reduced after 4 days of treatment and completely inhibited after 7 days. No significant differences were observed between the two SAP-dressings tested. CONCLUSION These in vitro experiments impressively demonstrated the antimicrobial mechanism of SAP-containing wound dressings: rapid up-take of fluid, binding of microorganisms to the SAP-core, and retention of the bacteria inside the dressing. Moreover, it could be shown that they are able to exhibit their antimicrobial activity over a prolonged period of time unless the amount of fluid present exceeds their fluid-handling capacity.

Abstract
Films are nanoscopic elements of foams, emulsions, and suspensions that form a paradigm for nanochannel transport that eventually tests the limits of hydrodynamic descriptions. Here, we study the collapse of a freestanding film to its equilibrium. The generation of nanoscale films usually is a slow linear process; using thermal forcing we find unprecedented dynamics with exponentially fast thinning. The complex interplay of thermal convection, interface, and gravitational forces yields optimal turbulent mixing and transport. Domains of collapsed film are generated, elongated, and convected in a beautiful display of chaotic mixing. With a time scale analysis, we identify mixing as the dominant dynamical process responsible for exponential thinning.

Abstract
High-intensity focused ultrasound (HIFU) is a rapidly maturing technology with diverse clinical applications. In the field of oncology, the use of HIFU to non-invasively cause tissue necrosis in a defined target, a technique known as focused ultrasound surgery (FUS), has considerable potential for tumour ablation. In this article, we outline the development and underlying principles of HIFU, overview the limitations and commercially available equipment for FUS, then summarise some of the recent technological advances and experimental clinical trials that we predict will have a positive impact on extending the role of FUS in cancer therapy.

Abstract
OBJECTIVE This study compares treatment with a polihexanide-containing biocellulose wound dressing (BWD+PHMB) versus the best local standard of silver dressings (Ag) in painful, critically colonised (wounds-at-risk) or locally-infected wounds. METHOD Patients with wounds of various aetiologies, a baseline VAS pain score >4 and a semi-quantitative bacterial load of ++ or higher were randomly allocated to receive treatment with either BWD+PHMB or Ag. Patients with systemic infections and/or using systemic antibiotics were excluded. The primary endpoint, patient-reported pain (VAS total pain, including the sub-scores pain at night, during the day, before, and 15min after dressing changes), was compared between treatment groups and scored on days 0, 1, 3, 7, 14, 21 and 28. Secondary outcomes of bacterial load, wound bed and periwound skin condition, quality of life and dressing handling were assessed at the same visits. RESULTS Thirty-eight patients (BWD+PHMB, n=21 [24 wounds]; Ag, n=17 [18 wounds]) were included in the analyses. Baseline variables showed no significant differences. Wound pain was reduced significantly in both groups, with a better pain reduction noted for BWD+ PHMB (p<0.001) before dressing changes. Compared with Ag, in the BWD+PHMB group critical colonisation and local wound infection had been reduced significantly faster and better (p<0.001) over the 28-day study period. Improved quality of life, good tolerability and no adverse events were demonstrated for both groups. CONCLUSION Both BWD+PHMB and AG were effective in reducing pain and bacterial burden. However, that BWD+PHMB was significantly faster and better in removing the critical bacterial load, makes this dressing an attractive therapeutic option to treat critically colonised and locally-infected wounds.

Abstract
BACKGROUND In Hong Kong, at the time of the study, compression treatment was not considered usual care for venous leg ulcer patients. AIM This randomized controlled trial compared quality of life (QOL) aspects in venous leg ulcer patients of over 55-years of age, of short-stretch compression (SSB), four-layer compression bandaging (4LB) and usual care (UC) (moist wound healing dressing, no compression). METHOD Study period was 24-weeks, the primary outcome was the patient functional status, disease-specific and generic health-related QOL measures and ulcer healing rates, comparing week 1 vs. week 24 (end) results. Assessments included photogrammetry, Brief Pain Inventory, SF-12 Health Survey, Charing Cross Venous Ulcer Questionnaire and Frenchay Activity Index. Data analysis was performed using, where appropriate; Kaplan Meier and log rank chi-square and the repeated measures analysis of variance test. RESULTS A total of 321 patients participated in the study, 45 (14%) withdrew for various reasons. Compression bandaging in both groups significantly reduced pain (P < 0.0001) and improved functional status and QOL. Healing rate at 24 weeks for both compression groups was significant (P < 0.001); for SSB this was 72.0% (77/107) vs. 67.3% in the 4LB group (72/107) and 29.0% (31/107) with usual care. The reduction in ulcer area from weeks 12 to 24 was significant only for SSB (P < 0.047). CONCLUSION Compression was shown to be feasible for elderly community care patients in Hong Kong and is currently implemented as part of standard venous leg ulcer treatment.

Abstract
A comprehensive in vitro approach was used to assess the effects of superabsorbent polymer (SAP) containing wound dressings in treatment of non-healing wounds. A slight negative effect on HaCaT cells was noted in vitro which is most likely due to the Ca(2+) deprivation of the medium by binding to the SAP. It could be shown that SAP wound dressings are able to bind considerable amounts of elastase reducing enzyme activity significantly. Furthermore, SAP's inhibit the formation of free radicals. The SAP-containing wound dressings tested also exhibited a significant to strong antimicrobial activity effectively impeding the growth of gram-negative and gram-positive bacteria as well as yeasts. In conclusion, in vitro data confirm the positive effect of SAP wound dressings observed in vivo and suggest that they should be specifically useful for wound cleansing.

Abstract
In the western industrial nations the proportion of old people (according to WHO definition people over 75 years) has been rising for many years and with it the amount of surgical treatment on this group of the population. High age does not automatically mean a risk too high for surgical treatment. Very often the reasons for this age group being high-risk patients are hospital admission in an advanced stage of illness or complications due to the illness. Old people are biologically younger than they were years ago. Often they express their perfectly understandable wish for suitable treatment. New treatments and strategies in surgery such as minimal-invasive surgery, endoluminal techniques for heart and vascular surgery, fast-track-concepts, anaesthetising techniques like spinal anaesthesia or the use of better controllable narcotics, improves alleviation of pain, quick mobilisation and early oral nutrition contribute to a minimisation of the risk. Age-related multimorbidity defines the risks of major operations and requires an individual weighing up of benefit and risk. The decision for or against an operation must take the elderly patient's wishes into account. The most important aspect is not only to help the people survive but to enable them to participate in life. In this paper we try to give an overview of geriatric surgery with all its aspects relevant to insurance.

Abstract
AIM A mainstay of lymphedema management involves the use of compression therapy. Compression therapy application is variable at different levels of disease severity. Evidence is scant to direct clinicians in best practice regarding compression therapy use. Further, compression clinical trials are fragmented and poorly extrapolable to the greater population. An ideal construct for conducting clinical trials in regards to compression therapy will promote parallel global initiatives based on a standard research agenda. The purpose of this article is to review current evidence in practice regarding compression therapy for BCRL management and based on this evidence, offer an expert consensus recommendation for a research agenda and prescriptive trials. Recommendations herein focus solely on compression interventions. METHODS This document represents the proceedings of a session organized by the International Compression Club (ICC) in June 2009 in Ponzano (Veneto, Italy). The purpose of the meeting was to enable a group of experts to discuss the existing evidence for compression treatment in breast cancer related lymphedema (BCRL) concentrating on areas where randomized controlled trials (RCTs) are lacking. RESULTS The current body of research suggests efficacy of compression interventions in the treatment and management of lymphedema. However, studies to date have failed to adequately address various forms of compression therapy and their optimal application in BCRL. We offer recommendations for standardized compression research trials for prophylaxis of arm lymphedema and for the management of chronic BCRL. Suggestions are also made regarding; inclusion and exclusion criteria, measurement methodology and additional variables of interest for researchers to capture. CONCLUSION This document should inform future research trials in compression therapy and serve as a guide to clinical researchers, industry researchers and lymphologists regarding the strengths, weaknesses and shortcomings of the current literature. By providing this construct for research trials, the authors aim to support evidence-based therapy interventions, promote a cohesive, standardized and informative body of literature to enhance clinical outcomes, improve the quality of future research trials, inform industry innovation and guide policy related to BCRL.

Abstract
BACKGROUND Indoleamine 2,3 dioxygenase (IDO), the rate-limiting enzyme in tryptophan catabolism, is important in generating tolerance at the foetal-maternal interface. Studies using 1-methyl-tryptophan (1-MT), the specific inhibitor of IDO, showed that this enzyme is important in interferon-gamma (IFN-gamma)-dependent inhibition of allergic inflammation in the respiratory airway during immunotherapy. AIMS OF STUDY We investigated the role of IDO in the development of allergic sensitization, leading to allergic inflammation and airway hyper-responsiveness (AHR). METHODS We used a mouse model to generate mucosal tolerance to lipopolysaccharide-free ovalbumin (OVA) following repeated intranasal inoculation of OVA over a 3-day period. We tested the successful induction of tolerance by subsequent intraperitoneal (i.p.) sensitization followed by intranasal challenge with OVA. A slow-release pellet of 1-MT implanted into mice was used to block IDO activity prior to repeated intranasal inoculation of OVA. We measured T-cell proliferation in response to OVA, determined airway inflammation, and measured AHR to intranasal methacholine to investigate the role of IDO in sensitization to OVA. RESULTS Repeated intranasal administration of OVA generated tolerance and prevented a subsequent sensitization to OVA via the i.p. route. This response was inhibited in mice receiving a slow-release pellet of 1-MT. However, we successfully reconstituted tolerance in mice receiving 1-MT following intra-peritoneal injection of a mixture of kynurenine and hydroxyanthranilic acid. CONCLUSION Our data suggest that, in addition to their role in IFN-gamma-mediated inhibition of allergic airway inflammation, products of tryptophan catabolism play an important role in the prevention of sensitization to potential allergens in the respiratory airway.

Abstract
This prospective longitudinal multicenter study of ambulatory children with cerebral palsy (CP) examined changes in outcome tool score over time, tool responsiveness, and used a systematic method for defining minimum clinically important differences (MCIDs). Three hundred and eighty-one participants with CP (Gross Motor Function Classification System [GMFCS] Levels I-III; age range 4-18y, mean age 11y [SD 4y 4mo]; 265 diplegia, 116 hemiplegia; 230 males, 151 females). At baseline and follow-up at least 1 year later, Functional Assessment Questionnaire, Gross Motor Function Measure, Pediatric Quality of Life Inventory, Pediatric Outcomes Data Collection Instrument, Pediatric Functional Independence Measure, temporal-spatial gait parameters, and oxygen cost were collected. Adjusted standardized response means determined tool responsiveness for nonsurgical (n=292) and surgical (n=87) groups at GMFCS Levels I to III. Most scores reaching medium or large effect sizes were for GMFCS Level III. Nonsurgical group change scores were used to calculate MCID thresholds for ambulatory children with CP. These values were verified by examining participants who changed GMFCS levels. Tools measuring function were responsive when a change large enough to cause a change in GMFCS level occurred. MCID thresholds assess change in study populations over time, and serve as the basis for designing prospective intervention studies.

Abstract
Recently, we investigated the adsorption of octachloro zinc phthalocyanine (ZnPcCl(8)) on Ag(111) by scanning tunneling microscopy. Compared to the standard phthalocyanine, halogenated phthalocyanine molecules show a much more complex binding behavior, which results in the formation of three different structural phases. These phases follow from the ordering process with the formation of 8, 4 and 0 intermolecular hydrogen-halogen bonds (Abel et al 2006 ChemPhysChem 7 82). In the present work we investigate these phases by Kelvin probe force microscopy in order to quantitatively deduce the electric interface barrier of the first monolayer. Our measurements reveal that the binding behavior does not only affect the structural ordering but also the interface dipole formation, which leads to different work functions. The fact that we observe interface barriers of opposite signs between ordered and disordered molecular layers underlines the importance of exactly knowing the molecular arrangement at the interface when assembling organic molecule devices.
