Abstract
Background and study aim Lately, mast cells (MCs) are increasingly implicated in the pathophysiology of irritable bowel syndrome (IBS). The aim of this systematic review was to assess the efficacy of mast cell directed therapies in reducing the main symptoms of IBS: abdominal pain and changes in stool frequency or consistency. Patients and methods Pubmed, Web of Science and Scopus were searched until December 19, 2022. Trials evaluating the efficacy of mast cell directed therapies, compared to placebo or any form of control group, were included. Trial selection was performed in two stages: screening titles and abstracts and reviewing full papers identified as relevant, taking into account the inclusion criteria. Results The search strategy identified a total of 1.384 citations. Eleven trials on 943 IBS patients and 197 controls were included: ten randomized controlled trials, two of which cross-over trials, and one cohort study. Of the 11 studies included in the systematic review, only three studies were found to be at low risk of bias. This limited evidence suggests a significant overall improvement in the key symptoms after treatment with disodium cromoglycate, ebastine, ketotifen or palmitoylethanolamide-polydatin compared to control groups. Conclusions Mast cell modulating therapies could be of significant value in therapy for IBS patients. Further high-quality research is needed to establish the therapeutic efficacy of mast cell targeted therapies in order to draw robust conclusions and improve the clinical management of irritable bowel syndrome.

Abstract
Despite the global recognition of domestic and family violence (DFV) as an outcome of unequal power relations between men and women, dominant frameworks for addressing DFV do not target the structural nature of the problem. Drawing on research conducted in partnership with the Federation of Community Legal Centres in Australia, we argue that a distinction needs to be made between what is genuinely structural change and what is system reform. Using intersectional feminist and decolonial theory and praxis, we reflect on what a structural approach to DFV could look like: one that confronts and actively tries to change the structural conditions that give rise to women's individual and collective vulnerability and victimization.

Abstract
BACKGROUND AND OBJECTIVES Mast cell (MC) degranulation via activation of the Mas-related G protein-coupled receptor X2 (MRGPRX2) plays a key role in immediate drug hypersensitivity (IDH). However, data in humans are limited to observations in specific cell lines. Objective: To study the usefulness of silencing MRGPRX2 in human MCs with the aim of further unveiling the MRGPRX2 pathway in IDH. METHODS MCs were cultured from CD34+ progenitor cells obtained from peripheral blood (PBCMCs) and incubated with substance P (as a positive control), rocuronium, moxifloxacin, morphine, or amoxicillin. Immunophenotyping of the cells included flow cytometry and microscopy analyses of the expression of CD117, CD203c, and MRGPRX2. Intracellular calcium was measured using Fluo-4. Degranulation was analyzed by quantifying CD63 expression. For MRGPRX2 silencing, MCs were electroporated with Dicer small interference RNAs. RESULTS Incubation of MCs with substance P, morphine, and moxifloxacin increased intracellular calcium levels and triggered MC degranulation, which, for the drugs, is almost completely abolished by selective MRGPRX2 silencing. Despite an increase in intracellular calcium in MRGPRX2+ cells, incubation with nontoxic concentrations of rocuronium does not result in degranulation of PBCMCs. Amoxicillin has no effect on PBCMCs. CONCLUSION The use of MRGPRX2 silencing in human MCs can provide important insights into the role of MRGPRX2 in the pathogenesis of IDH. As induction of calcium signals does not necessarily translate into a secretory response, measurement of the degranulation reaction seems more meaningful in the context of drug testing.

Abstract
Stigma is one of the greatest challenges facing people with severe mental illness (smi) and can have profound psychological, social and professional consequences.<br/> AIM: To systematically review the evidence of effectiveness of anti-stigma interventions (anti-stigma campaigns and specific interventions to reduce public stigma and self-stigma) for people with smi and to make recommendations for clinical practice.<br/> METHOD: A systematic literature search for individual studies and reviews concerning the efficacy of interventions that reduce stigma for people with smi.<br/> RESULTS: Anti-stigma interventions have small-to-medium effects. Although head-to-head comparisons do not show a clear advantage for educational or contact interventions, results suggest that the elements of contact, recovery and continuity (for public stigma) and psycho-education (for self-stigma) may yield the greatest effects. Due to the short follow-up period of most studies, there is limited evidence on the long-term effectiveness of these interventions. More specifically, it remains unknown whether these interventions lead to changes in actual behavior.<br/> CONCLUSION: Anti-stigma interventions have limited effects on knowledge, attitudes and behavior. Several methodological shortcomings, as well as short follow-up periods in most studies, preclude making firm conclusions.

Abstract
Modern head and neck reconstructive surgery offers a multitude of different reconstructive options. In such cases, donor site morbidity is an important factor in the affected patient's decision-making. The aim of this study was to perform an objective comparison of donor site morbidity for the five most frequent microvascular donor sites in head and neck reconstructive surgery (radial forearm, anterolateral thigh, fibula, iliac crest, and scapula) using a uniform testing system. In this cross-sectional study, 117 donor sites were analyzed (106 for malignant disease and 11 for non-malignant disease): 73 radial forearm, 14 scapula, 12 anterolateral thigh, 10 fibula, and eight iliac crest. Testing consisted of range of motion, muscle strength, and sensation. The non-affected side served as the control. Quality of life was assessed using the Washington Quality of Life Questionnaire version 4 in its German translation. Range of motion was restricted in 15 cases (12.8%). Muscle strength was decreased in 58 cases (49.6%). Sensation was reduced in 70 cases (60%). Concerning quality of life, 31.2% of patients were limited in their daily activities. The scapula flap showed the highest incidence of overall donor site morbidity. However, correlation between objective and subjective donor site impairment was weak and the majority of patients experienced only minor limitations.

Abstract
Immediate drug hypersensitivity reactions (IDHR) to moxifloxacin constitute a pathomechanistic conundrum and a diagnostic challenge. Our objective was to study whether simultaneous phenotyping and quantification of histamine release might add to our knowledge about the basophil activation properties of moxifloxacin and constitute a reliable diagnostic aid. Fifteen patients with an IDHR to moxifloxacin and nine moxifloxacin challenged controls were selected. All had a basophil activation test (BAT) with moxifloxacin. Flow cytometric analysis of basophil responses implied labeling for CD63, CD203c, and intracellular histamine. Unlike tolerant challenged controls, basophilic upregulation of CD203c in response to moxifloxacin was observed in seven of 15 patients. Only two of these seven patients demonstrated appearance of CD63 and release of histamine. In the remainder eight patients, no basophil responses were demonstrable. In conclusion, immediate hypersensitivity to moxifloxacin might involve mechanisms difficult to capture by traditional CD63-/CD203c-based BAT. Deciphering the complexity of quinolone IDHR seems mandatory.

Abstract
IgE-mediated Cannabis (C. sativa, marihuana) allergy seems to be on the rise. Both active and passive exposure to cannabis allergens may trigger a C. sativa sensitization and/or allergy. The clinical presentation of a C. sativa allergy varies from mild to life-threatening reactions and often seems to depend on the route of exposure. In addition, sensitization to cannabis allergens can result in various cross-allergies, mostly for plant foods. This clinical entity, designated as the 'cannabis-fruit/vegetable syndrome', might also imply cross-reactivity with tobacco, natural latex and plant-food-derived alcoholic beverages. Hitherto, these cross-allergies are predominantly reported in Europe and appear mainly to rely upon cross-reactivity between nonspecific lipid transfer proteins or thaumatin-like proteins present in C. sativa and their homologues, ubiquitously distributed throughout plant kingdom. At present, diagnosis of cannabis-related allergies predominantly rests upon a thorough history completed with skin testing using native extracts from crushed buds and leaves. However, quantification of specific IgE antibodies and basophil activation tests can also be helpful to establish correct diagnosis. In the absence of a cure, treatment comprises absolute avoidance measures. Whether avoidance of further use will halt the extension of related cross-allergies remains uncertain.

Abstract
Human corneal endothelial cells (HCEC) maintain appropriate tissue hydration and transparency by eliciting net ion transport coupled to fluid egress from the stroma into the anterior chamber. Such activity offsets tissue swelling caused by stromal imbibition of fluid. As corneal endothelial (HCE) transport function is modulated by temperature changes, we probed for thermosensitive transient receptor potential melastatin 8 (TRPM8) functional activity in immortalized human corneal endothelial cells (HCEC-12) and freshly isolated human corneal endothelial cells (HCEC) as a control. This channel is either activated upon lowering to 28 °C or by menthol, eucalyptol and icilin. RT-PCR and quantitative real-time PCR (qPCR) verified TRPM8 gene expression. Ca(2+) transients induced by either menthol (500 μmol/l), eucalyptol (3 mmol/l), or icilin (2-60 μmol/l) were identified using cell fluorescence imaging. The TRP channel blocker lanthanum III chloride (La(3+), 100 μmol/l) as well as the TRPM8 blockers BCTC (10 μmol/l) and capsazepine (CPZ, 10 μmol/l) suppressed icilin-induced Ca(2+) increases. In and outward currents induced by application of menthol (500 μmol/l) or icilin (50 μmol/l) were detected using the planar patch-clamp technique. A thermal transition from room temperature to ≈ 18 °C led to Ca(2+) increases that were inhibited by a TRPM8 blocker BCTC (10 μmol/l). Other thermosensitive TRP pathways whose heterogeneous Ca(2+) response patterns are suggestive of other Ca(2+) handling pathways were also detected upon strong cooling (≈10 °C). Taken together, functional TRPM8 expression in HCEC-12 and freshly dissociated HCEC suggests that HCE function can adapt to thermal variations through activation of this channel subtype.

Abstract
BACKGROUND Development of a geriatric screening tool is necessary to identify elderly cancer patients who would benefit from comprehensive geriatric assessment (CGA). We develop and evaluate the G-8 screening tool against various reference tests. PATIENTS AND METHODS Analyses were based on 364 cancer patients aged>70 years scheduled to receive first-line chemotherapy included in a multicenter prospective study. The G-8 consists of seven items from the Mini Nutritional Assessment (MNA) questionnaire and age. Our primary reference test is based on a set of seven CGA scales: Activities Daily Living (ADL), Instrumental ADL, MNA, Mini-Mental State Exam, Geriatric Depression Scale, Cumulative Illness Rating Scale-Geriatrics, and Timed Get Up and Go. We considered the presence of at least one questionnaire with an impaired score as an abnormal reference exam. Additional reference exams are also discussed. RESULTS The prevalence of being at risk varied from 60% to 94% according to the various definitions of the reference test. When considering the primary reference test, a cut-off value of 14 for the G-8 tool provided a good sensitivity estimate (85%) without deteriorating the specificity excessively (65%). CONCLUSION The G-8 shows good screening properties for identifying elderly cancer patients who could benefit from CGA.

Abstract
Spectrum unfolding is a powerful method that can enhance the readability of experimental energy spectra obtained by detectors of poor resolution. It is applied to the NaI-based monitor. The UMG 3.3 package is used for unfolding the experimental spectra with the response matrix obtained by MCNP4c2. The main parameter influencing the quality of the results is the chi(2). The goal of this study is to optimize the choice of this factor. The statistical accuracy of the technique is evaluated.

Abstract
As a first step into the development of a neutron dose monitor, a stilbene detector is used to test a procedure applicable to other organic scintillators allowing for neutron-photon discrimination. The pulses are measured by numerical acquisition and their amplitude and decay time are calculated by software. The discrimination is performed in an amplitude-decay time plot, and separate amplitude spectra are built. These spectra are unfolded MAXED, using the detector response matrices calculated with MCNPX.

Abstract
9040 Background: When it is time to decide for or against chemotherapy in elderly patients (pts) with cancer, physicians face the difficult balance of risks and benefits. Too much often, decision is based on empirical feelings rather than reliable and objective factors which are frequently lacking. Yet, elderly pts can benefit from chemotherapy in many situations. Method: To help physicians in the decision process of chemotherapy through identification of factors predicting early death (< 6 months) from the onset of chemotherapy, we performed a prospective accrual of pts older than 70 with various types of cancer treated by 1st line chemotherapy. Baseline geriatric assessment (GA) (MMS, Get up and go, ADL, IADL, MNA, GDS15 , CIRS-G). Treatment was applied by the oncologist according to current standards disregarding GA results. Factors tested were: age, sex, advanced disease, renal and cardiac function, blood counts, performance status (PS), comorbidities and GA data. Results: 364 pts were accrued in 12 centres. Localisations were: lymphomas (110), colon (101), stomach (37), lung (37), pancreas (23), prostate (20), bladder (18), ovary (14) and unknown origin carcinomas (4). Main characteristics: median age (77.5 y. - range: 70- 99), sex ratio H/F (1.43), advanced tumours (66% - metastatic cancer or aaIPI 2–3 for lymphomas), PS>1 (28%), creatinine clearance <50 ml/mn (42%). GA showed 32% of pts ADL-dependent, 70% IADL-dependent, risk of falls in 12.4%, 19.2% MMS<24, 30% GDS15 >6, 63.4% MNA<23.5, 38.2% = 1 CIRS-G gr. 3–4 category. 357 pts have been followed up for more than 6 months and 59 pts died during this period. Only advanced disease (OR: 4.2 - CI95:1.7–10.3) and MNA score (OR: 4.5 - CI95: 1.75–11.6) predicted early death in logistic regression model. In advanced tumours, risk of early death varied from 11% in pts with MNA>23.5 to 40% in pts with MNA<17. Conclusions: In pts older than 70 with cancer, disease extension and MNA could predict for early death. MNA, performed by a trained nurse, should probably be added to routine pre- treatment work-up in these pts to screen for multidisciplinary assessment and management by oncologists and geriatricians.

Abstract
Plakophilin 2, a member of the arm-repeat protein family, is a dual location protein that occurs both in the cytoplasmic plaques of desmosomes as an architectural component and in an extractable form in the nucleoplasm. Here we report the existence of two nuclear particles containing plakophilin 2 and the largest subunit of RNA polymerase (pol) III (RPC155), both of which colocalize and are coimmunoselected with other pol III subunits and with the transcription factor TFIIIB. We also show that plakophilin 2 is present in the pol III holoenzyme, but not the core complex, and that it binds specifically to RPC155 in vitro. We propose the existence of diverse nuclear particles in which proteins known as plaque proteins of intercellular junctions are complexed with specific nuclear proteins.
