Background: Homelessness and housing instability in the host countries are central features of the experience of migration to the EU. Although migrant women across the EU encounter obstacles in accessing healthcare services, little is known on the health and access to healthcare services for unstably housed migrant women. The DSAFHIR project aims to better describe the risks faced by migrant women in situations of administrative and social vulnerability, to analyze the barriers to access healthcare and to test specific health interventions.
Methods: The DSAFHIR project consists of a two-wave mixed-method survey and the implementation of two tailored sexual health interventions. 474 migrant women aged 18 to 77 years housed in social hotels were surveyed at inclusion. After the implementation of sexual health interventions, respondents were contacted for the follow-up survey (n=284).
Discussion: The project provides needed data on migrant women’s health and healthcare access, including non-French speakers. It allows to draw lessons on feasibility and acceptability of quantitative and qualitative surveys on this hard-to-reach population. A high response rate in both waves of the survey (84% and 85%) suggests good acceptability. The attrition is comparable to other migrant longitudinal surveys (60% of the original sample completed the follow-up survey, or 40% of attrition), suggesting that relying on cell phones is possible for follow-up even in contexts of housing instability.
No Waste Cooking – An Exploration of Politics as Redistribution of the Sensible
Authors: Gunnerød Sissel 
Published: December 2019

Life in affluent, big city society with huge amounts of easily accessible food results in extensive food waste on different levels, causing greenhouse gas emissions. The aim of this article is to explore and discuss whether—and if so, how—an urban art action may contribute to displacement in social food practices. Using the Swedish artist Andrea Hvistendahl’s ongoing project No Waste Cooking as a case study, I approach this art action through Jacques Rancière’s concept of politics as distribution and redistribution of the sensible. The most important research questions are: How is No Waste Cooking involved in redistributing social food waste practices? How is the project related to similar projects in visual culture?
No Waste Cooking concerns saving and upgrading food from grocery stores that would otherwise be thrown away. As an urban gleaner, Hvistendahl gathers this food and intervenes between grocery stores and consumers, creating a space for leftovers, sensations and reflections. Food after its expiration date has become the fulcrum, the third thing, a common reference in which the artist, the visitors, as well as the readers are invited to reassess our values and behavior patterns on food, and elaborate and develop further discussion and proliferation. In this sense, No Waste Cooking has a didactic function, displaying ethical questions and possible ways to deal with them without straightforward answers. Albeit in a modest alteration, art becomes life.

AbstractObjectiveDevelopment of biomarkers for Charcot‐Marie‐Tooth (CMT) disease is critical for implementing effective clinical trials. The most common form of CMT, type 1A, is caused by a genomic duplication surrounding the PMP22 gene. A recent report (Neurology 2018;90:e518–3524) showed elevation of neurofilament light (NfL) in plasma of CMT1A disease patients, which correlated with disease severity. However, no plasma/serum biomarker has been identified that is specific to Schwann cells, the most directly affected cells in CMT1A.MethodsWe used the Olink immuno PCR platform to profile CMT1A patient (n = 47, 2 cohorts) and normal control plasma (n = 41, two cohorts) on five different Olink panels to screen 398 unique proteins.ResultsThe TMPRSS5 protein (Transmembrane protease serine 5) was elevated 2.07‐fold (P = <0.0001) in two independent cohorts of CMT1A samples relative to controls. TMPRSS5 is most highly expressed in Schwann cells of peripheral nerve. Consistent with early myelination deficits in CMT1A, TMPRSS5 was not significantly correlated with disease score (CMTES‐R, CMTNS‐R), nerve conduction velocities (Ulnar CMAP, Ulnar MNCV), or with age. TMPRSS5 was not significantly elevated in smaller sample sets from patients with CMT2A, CMT2E, CMT1B, or CMT1X. The Olink immuno PCR assays confirmed elevated levels of NfL (average 1.58‐fold, P < 0.0001), which correlated with CMT1A patient disease score.InterpretationThese data identify the first Schwann cell‐specific protein that is elevated in plasma of CMT1A patients, and may provide a disease marker and a potentially treatment‐responsive biomarker with good disease specificity for clinical trials.

Published: December 2019

SummaryBehaviour detection officers' task is to spot potential criminals in public spaces, but scientific research concerning what to look for is scarce. In two experiments, 52 (Experiment 1A) and 60 (Experiment 2A) participants carried out a mission involving a ferry crossing. Half were asked to smuggle an object; the other half were non‐smugglers. In Experiment 2A, two confederates appeared to approach as if looking for someone on the ferry. Smugglers, more than non‐smugglers, reported afterwards to have felt nervous, self‐conscious, and conspicuous and to attempt behavioural control during the ferry crossing. The secretly videotaped ferry crossings were shown to 104 (Experiment 1B) and 120 (Experiment 2B) observers, tasked to identify the smugglers. Although they reported paying attention mostly to signs of nervousness, lie detection accuracy rate was poor (48% in Experiment 1 and 39.2% in Experiment 2) because their perceptions of nervousness did not match the experiences of nervousness reported by the (non)smugglers.

AbstractConductive hydrogels have emerged as fascinating materials applied in flexible electronics because of their integrated conductivity and mechanical flexibility. However, the large amounts of water in conductive hydrogels inevitably freeze at subzero temperature, causing a reduction of their ionic transport ability and elasticity. Herein, the bioinspired antifreezing agents—zwitterionic osmolytes (e.g., betaine, proline) are first proposed to prevent ammonium chloride‐containing Ca‐alginate/polyacrylamide hydrogels from freezing. With a facile one‐pot solvent displacement method, the zwitterionic osmolytes can displace the water molecules inside the hydrogels. Due to the excellent freeze tolerance of zwitterionic osmolytes, the resulting zwitterionic osmolyte‐based hydrogels exhibit outstanding ionic conductivity (up to ≈2.7 S m−1) at −40 °C, which exceeds the conductivities of most reported conductive hydrogels. Meanwhile, they present stable mechanical flexibility over a wide temperature range (−40 to 25 °C). More importantly, two types of the resulting hydrogel‐based flexible electronics, including a capacitive sensor and a resistive sensor, can maintain their response function at −40 °C. This work offers a new solution to fabricate conductive hydrogels with antifreezing ability, which can broaden the working temperature range of flexible electronics.

AbstractThe conversion of metal–organic frameworks (MOFs) into derivatives with a well‐defined shape and composition is considered a reliable way to produce efficient catalysts and energy capacitors at the nanometer scale. Yet, approaches based on conventional melting of MOFs provide the derivatives such as amorphous carbon, metal oxides, or metallic nanoclusters with an appropriate morphology. Here ultrafast melting of MOFs is utilized by femtosecond laser pulses to produce a new generation of derivatives with complex morphology and enhanced nonlinear optical response. It is revealed that such a nonequilibrium process allows conversion of interpenetrated 3D MOFs comprising flexible ligands into well‐organized spheres with a metal oxide dendrite core and amorphous organic shell. The ability to produce such derivatives with a complex morphology is directly dependent on the electronic structure, crystal density, ligand flexibility, and morphology of initial MOFs. An enhanced second harmonic generation and three‐photon luminescence are also demonstrated due to the resonant interaction of 100–1000 nm spherical derivatives with light. The results obtained are in the favor of new approaches for melting special types of MOFs for nonlinear nanophotonics.

AbstractThe development of bioadhesives has become an emerging research field for tissue sealants, wound dressings, and hemostatic agents. However, assembling hydrogels using bioadhesive‐mediated attachment remains a challenging task. Significantly high water content (>90%) in hydrogels compared to that of biological tissues is the main cause of failure. Considering that hydrogels are primary testing scaffolds mimicking in vivo environments, developing strategies to assemble hydrogels that exhibit diverse properties is important. Self‐healing gels have been reported, but such gels often lack biocompatibility, and two gel pieces should be identical in chemistry for assembly, thus not allowing co‐existence of diverse biological environments. Herein, a mussel‐mimetic cis‐diol‐based adhesive, alginate‐boronic acid, that exhibits pH‐responsive curing from a viscoelastic solution to soft gels is developed. Associated mechanisms are that 1) polymeric diffusion occurs at interfaces utilizing intrinsic high water content; 2) the conjugated cis‐diols strongly interact/entangle with hydrogel chains; 3) curing processes begin by a slight increase in pH, resulting in robust attachment of diverse types of hydrogel building blocks for assembly. The findings obtained with alginate‐boronic acid glues suggest a rational design principle to attach diverse hydrogel building blocks to provide platforms mimicking in vivo environments.

Scalable Electronic Ratchet with Over 10% Rectification Efficiency

Published: December 2019

AbstractElectronic ratchets use a periodic potential with broken inversion symmetry to rectify undirected (electromagnetic, EM) forces and can in principle be a complement to conventional diode‐based designs. Unfortunately, ratchet devices reported to date have low or undetermined power conversion efficiencies, hampering applicability. Combining experiments and numerical modeling, field‐effect transistor‐based ratchets are investigated in which the driving signal is coupled into the accumulation layer via interdigitated finger electrodes that are capacitively coupled to the field effect transistor channel region. The output current–voltage curves of these ratchets can have a fill factor >> 0.25 which is highly favorable for the power output. Experimentally, a maximum power conversion efficiency well over 10% at 5 MHz, which is the highest reported value for an electronic ratchet, is determined. Device simulations indicate this number can be increased further by increasing the device asymmetry. A scaling analysis shows that the frequency range of optimal performance can be scaled to the THz regime, and possibly beyond, while adhering to technologically realistic parameters. Concomitantly, the power output density increases from ≈4 W m−2 to ≈1 MW m−2. Hence, this type of ratchet device can rectify high‐frequency EM fields at reasonable efficiencies, potentially paving the way for actual use as energy harvester.

AbstractLi‐rich oxide is a promising candidate for the cathodes of next‐generation lithium‐ion batteries. However, its utilization is restricted by cycling instability and inferior rate capability. To tackle these issues, three‐dimensional (3D), hierarchical, cube‐maze‐like Li‐rich cathodes assembled from two‐dimensional (2D), thin nanosheets with exposed {010} active planes, are developed by a facile hydrothermal approach. Benefiting from their unique architecture, 3D cube‐maze‐like cathodes demonstrate a superior reversible capacity (285.3 mAh g−1 at 0.1 C, 133.4 mAh g−1 at 20.0 C) and a great cycle stability (capacity retention of 87.4% after 400 cycles at 2.0 C, 85.2% after 600 cycles and 75.0% after 1200 cycles at 20.0 C). When this material is matched with a graphite anode, the full cell achieves a remarkable discharge capacity (275.2 mAh g−1 at 0.1 C) and stable cycling behavior (capacity retention of 88.7% after 100 cycles at 5.0 C, capacity retention of 84.8% after 100 cycles at 20.0 C). The present work proposes an accessible way to construct 3D hierarchical architecture assembled from 2D nanosheets with exposed high‐energy active {010} planes and verifies its validity for advanced Li‐rich cathodes.
“That's not my job”: A mixed methods study of challenging client behaviors, boundaries, and home care aide occupational safety and health

Published: December 2019

AbstractIntroductionHome care (HC) aide is among the fastest‐growing jobs. Aides often work in long‐term care relationships with elders or people with disabilities in clients’ homes, assisting with daily activities. The purpose of this mixed‐methods paper is to elucidate aides’ experiences around the boundary‐challenging behaviors of clients asking for services beyond aides’ job duties and to identify possible interventions.MethodsA cross‐sectional survey of HC aides in Massachusetts (n = 1249) provided quantitative data. Post‐survey qualitative data were collected from nine HC aide focus groups (n = 70) and seven in‐depth interviews with HC industry and labor representatives.ResultsQuantitatively, aides who reported often being asked to do tasks outside their job duties were more likely to report abuse (prevalence ratio [PR] = 1.93; 95%CI: 1.47‐2.52 for verbal, PR = 1.81; 95%CI: 1.13‐2.91 for physical/sexual) and pain/injury with lost work time or medical care (PR = 1.58; 95%CI: 1.11‐2.25). They were also less likely to want to remain in their job (PR = 0.94; 95%CI: 0.89‐1.00) or recommend it to others (PR = 0.94; 95%CI: 0.90‐0.98). Qualitative data showed that clients’ requests for tasks beyond job duties were frequent and can lead to injuries, abuse, and psychosocial stress. Yet, requests often reflected genuine need. Helping clients stay at home, compassion, and feeling appreciated contributed to job satisfaction; therefore, aides can feel conflicted about refusing requests.ConclusionClient task requests outside HC services are a complex problem. Employer support, training, care plans, and feeling part of a care team can help aides navigate professional boundaries while delivering high quality care.

Published: December 2019

AbstractFamilial amniotic band sequence (ABS) is rare but has been reported in the offspring of mothers with connective tissue disorders. We present a family of two half‐siblings with ABS who share the same biological father. Following a serious vascular event a de novo pathogenic variant in COL3A1 was detected in the father, confirming a diagnosis of vascular Ehlers–Danlos syndrome (vEDS). The same variant was found in both his ABS‐affected children but not in his unaffected child. The amniotic membrane is derived from fetal tissue, type III collagen being a component. As the affected children are paternal half‐siblings, ABS was less likely due to maternal factors. Rather, the amniotic bands may have resulted from decreased type III collagen production as seen in people with vEDS, causing fragility of the amniotic membrane. Consequently, it is important to consider vEDS in patients with ABS.

AbstractPontocerebellar hypoplasia type 9 (PCH9) is an autosomal recessive neurodevelopmental disorder caused by pathogenic variants in the AMPD2 gene. We evaluated the son of a consanguineous couple who presented with profound hypotonia and global developmental delay. Other features included sensorineural hearing loss, asymmetric astigmatism, and high myopia. Clinical whole‐exome sequence analysis identified a homozygous missense variant in AMPD2 (NM_001257360.1:c.2201C > T, p.[Pro734Leu]) that has not been previously reported. Given the strong phenotypic overlap with PCH9, including the identification of the typical “Figure 8” appearance of the brainstem on neuroimaging, we suspect this variant was causative of the neurodevelopmental disability in this individual. An additional homozygous nonsense variant in COL11A1 (NM_001854.4:c.1168G > T, p.[Glu390Ter]) was identified. Variants in this alternatively spliced region of COL11A1 have been identified to cause an autosomal recessive form of Stickler syndrome type 2 characterized by sensorineural hearing loss and eye abnormalities, but without musculoskeletal abnormalities. The COL11A1 variant likely also contributed to the individual's phenotype, suggesting two potentially relevant genetic findings. This challenging case highlights the importance of detailed phenotypic characterization when interpreting whole exome data.

BackgroundThe taboo of avoiding nonsteroidal anti‐inflammatory drugs (NSAIDs) after functional endoscopic sinus surgery (FESS) has been waning. The impetus to reduce opioid prescriptions in view of the opioid epidemic led the authors to change their practices to include NSAIDs after sinus surgery. This study's aim was to analyze the differences between patients before and after we began recommending NSAIDs after FESS.MethodsA prospective cohort study was performed on patients undergoing FESS or other endoscopic nasal surgeries at 3 institutions, by 5 rhinologists and 1 facial plastic surgeon. Before introducing NSAIDs, all patients were given a prescription for hydrocodone‐acetaminophen 5/325 mg and also recommended preferentially to use acetaminophen 325 mg. After the addition of NSAIDs, ibuprofen 200 mg and acetaminophen 325 mg were recommended preferentially, using the narcotic as a rescue medication. Patients kept a pain diary and medication log, and gave a visual analog scale (VAS) score for overall pain. Demographics, surgical variables, and comorbidities were also analyzed.ResultsOne hundred sixty‐six total patients were recruited and had data that could be analyzed (65 without NSAIDs, 101 with NSAIDs). Overall, mean pain VAS score was 3.12 ± 1.95 for the non‐NSAID group and 2.33 ± 2.30 for the NSAID group (p value = 0.006). The day with the highest mean pain was the first postoperative day. The mean number of total opioid pills taken was 6.94 ± 6.85 without NSAIDs vs 3.77 ± 4.56 with NSAIDs (p = 0.018). Age and gender were found to be the only consistently significant patient variables to affect pain. There were no bleeding complications.ConclusionNSAID use was introduced into the practices of 5 practicing rhinologists and 1 facial plastic surgeon. No bleeding complications were seen. Both pain and overall opioid usage were reduced significantly.

AbstractWir berichten über die ersten Beispiele isolierter Silanol‐Silanolat‐Anionen unter Verwendung schwach koordinierender Phosphazenium‐Gegenionen. Die Silanolat‐Anionen wurden durch die Reaktion des kürzlich veröffentlichten Phosphazenium‐Hydroxid‐Hydrat‐Salzes mit Siloxanen synthetisiert. Die Silanol‐Silanolat‐Anionen sind postulierte Zwischenprodukte bei der Hydroxid‐vermittelten Polymerisation von Aryl‐ und Alkylsiloxanen. Die Silanolat‐Anionen sind wegen des schwach koordinierenden Charakters des Phosphazenium‐Kations starke Nucleophile. Diese Eigenschaft macht sich in ihrer Aktivität bei der Depolymerisation von Polysiloxanen bemerkbar.
