What’s Race Got to Do with It? The Interactive Effect of Race and Gender on Negotiation Offers and Outcomes
Authors: Leigh Angelica , Desai Sreedhari D. 
Published: September 2022

Research suggests that women negotiators tend to obtain worse outcomes than men; however, we argue this finding does not apply to all women. Integrating research on social hierarchies, gender in negotiations, and intersectional stereotype content, we develop a theoretical framework that explains the interactive effect of race and gender on offers and outcomes received in distributive negotiations. With a focus on Black and White women and men negotiators, we predicted that stereotypes related to their race and gender lead Black women negotiators to receive more favorable negotiation offers and outcomes than White women and Black men negotiators and this effect is explained by ascriptions of dominance and prestige, respectively. Results of three experimental studies involving diverse samples—online panel participants, individuals selling items on Craigslist, and MBA students—support these predictions. More specifically, we find that Black women negotiators are perceived as more dominant than White women negotiators, and Black women negotiators are ascribed greater prestige than Black men negotiators. These ascriptions allow Black women negotiators to receive more favorable negotiation offers and outcomes compared with White women and Black men. These findings highlight the importance of jointly considering the influence of race and gender in negotiations. Funding: This research was supported in part by funding offered to Dr. Sreedhari D.

Objective: To evaluate the efficacy, tolerability and acceptability of a new multicomponent compression system in one bandage for the local treatment of patients with venous leg ulcers (VLUs). Method: This was an international, prospective, non-comparative, clinical trial, conducted in France and Germany. Eligible participants had a VLU with a wound area of 2–20cm2, lasting for a maximum of 24 months. For a period of 6 weeks, patients were treated with a new multicomponent compression system in one bandage which was worn day and night, providing high working pressure and moderate resting pressure (UrgoK1). Clinical assessments, wound measurement and photographs were planned at weeks 1, 2, 4 and 6. The primary endpoint was the relative wound area reduction (RWAR) after 6 weeks of treatment. Secondary endpoints included wound closure rate, oedema resolution, change in patient's health-related quality of life (HRQoL), acceptability, adherence to the compression therapy, local tolerance, and physician's overall satisfaction with the evaluated compression system. Results: A cohort of 52 patients (52% female, mean age 75.4±13.0 years) with VLUs, including oedema in 58% of cases, were recruited from 22 centres. At baseline, 42 patients had already been treated with a different compression system. VLUs had been present for 5.6±4.9 months and had a mean area of 5.7±4.3cm2. After 6 weeks of treatment, a median RWAR of 91% (interquartile range: 39.4; 100.0) was achieved. Wound closure was reported in 35% of patients. A RWAR ≥40% at week 4, predictive of wound healing at 12 weeks, was achieved in 62% of patients. At the final visit, oedema present at baseline was resolved in 57% of patients. Substantial improvements in the HRQoL of the patients were reported with a decrease of the pain/discomfort and anxiety/depression dimensions. Comfort in wearing the evaluated system was reported as ‘very good’ or ‘good’ by 79% of patients, resulting in a high patient adherence to compression therapy. Compared to previous compression systems, half of the patients reported more ease in wearing shoes, and greater satisfaction and comfort with this new system. Nine non-serious adverse events related to the device or its procedure occurred in seven patients. At the final visit, the majority of the physicians were ‘very satisfied’ or ‘satisfied’ with the new compression system overall. Conclusion: The new multicomponent compression system in one bandage has been shown to promote rapid healing of VLUs, reduce oedema, improve HRQoL and to be well tolerated and accepted. It appears to be a viable alternative to existing compression systems.

Published: September 2022

Objective: Osteomyelitis is a limb-threatening complication of diabetic foot ulcers. Early identification of the disease is key to ensuring successful prognosis. In this study, we describe ultrasonographic features for the identification of osteomyelitis. Method: Patients were screened through clinical, ultrasonographic and probe-to-bone tests. Results: Ultrasonographic features in three patients that could be used to identify diabetic foot osteomyelitis included periosteal reaction, periosteal elevation, cortical erosions and presence of sequestrum, all of which were confirmed by a plain X-ray. Conclusion: An ultrasonographic examination could be used for the early detection of osteomyelitis, which could help clinicians devise prompt treatment strategies.

Published: September 2022

Objective: The aim of this case report is to describe the results of complex decongestive therapy (CDT) in a patient with poliomyelitis and bilateral lymphoedema, and to emphasise the effect of CDT on wound healing. Method: A 48-year-old female patient was given CDT for bilateral grade 3 lymphoedema in the lower extremities and a deep wound on the right foot. She had been diagnosed with poliomyelitis sequela and mobilised with a wheelchair for 26 years. The lymphoedema on both legs and the wound on the right foot sole had been present for five years and eight months, respectively. Detailed wound care had been performed previously upon the green, malodorous infected wound, without healing. The patient received skin care education, manual lymphatic drainage, multilayer bandaging and exercises for 4 weeks in a total of 20 sessions. The improvement was assessed by limb volumes prior to and at the end of the treatments. Results: The right and left lower limb volumes were decreased significantly at the end of treatments (3042cm³ (R) and 3165cm³ (L) before versus 2702cm3 (R) and 2401cm3 (L) afterward). The wound size decreased considerably and the green malodorous flow ceased. The patient continued self-massage and self-bandaging after hospital discharge. The control follow-up, one month later, revealed a completely healed wound with maintained volume. Conclusion: In conclusion CDT for a duration of 4 weeks in a female patient with poliomyelitis, bilateral lymphoedema and an infectious hard-to-heal wound, improved both the lymphoedema and wound healing.

Authors: Gonzalez Gilberto A , Castagno Christopher , Carter Jordan , Chellappan Brinda , Taupin Philippe 
Published: September 2022

Objective: The treatment of complex extremity wounds is technically challenging. In this 5-year retrospective review, we compared the use of Integra Meshed Bilayer Wound Matrix (IMBWM; Integra LifeSciences, US) followed by a split-thickness skin graft (STSG) combined with negative pressure wound therapy (NPWT) versus IMBWM followed by STSG alone for the management of these wounds. Method: Data from patients undergoing management using IMBWM for a complex extremity wound coverage were collected. Results: Among the 109 patients studied, the wounds of 62 patients were managed using IMBWM and NPWT, and 47 were managed using IMBWM alone. The most common aetiology of these injuries was trauma. Wound size and location were similar for each group, ranging in size from 2–30cm2 and being primarily on the forearm, followed by the leg and arm. There was a significantly greater take of the IMBWM+STSG with NPWT (96.8%) compared to without NPWT (85.1%, p=0.03). There were significantly fewer reapplications of the dermal matrix required in the NPWT group (3.2%) versus the non-NPWT group (14.9%, p=0.03). There were significantly fewer postoperative complications, prior to STSG, in the NPWT group (3.2%) versus the non-NPWT group (14.9%, p=0.03). Conclusion: The combination of IMBWM with NPWT leads to a higher success rate, and can reduce the number of dermal matrix reapplications and postoperative complications, in the setting of complex extremity wounds. The use of IMBWM in combination with NPWT has the potential to improve both surgical procedures and patient outcomes in this setting.

Published: September 2022

Aims We introduced a self-care pathway for minimally displaced distal radius fractures, which involved the patient being discharged from a Virtual Fracture Clinic (VFC) without a physical review and being provided with written instructions on how to remove their own cast or splint at home, plus advice on exercises and return to function. Methods All patients managed via this protocol between March and October 2020 were contacted by a medical secretary at a minimum of six months post-injury. The patients were asked to complete the Patient-Rated Wrist Evaluation (PRWE), a satisfaction questionnaire, advise if they had required surgery and/or contacted any health professional, and were also asked for any recommendations on how to improve the service. A review with a hand surgeon was organized if required, and a cost analysis was also conducted. Results Overall 71/101 patients completed the telephone consultation; no patients required surgery, and the mean and median PRWE scores were 23.9/100 (SD 24.9) and 17.0/100 (interquartile range (IQR) 0 to 40), respectively. Mean patient satisfaction with treatment was 34.3/40 (SD 9.2), and 65 patients (92%) were satisfied or highly satisfied. In total there were 16 contact calls, 12 requests for a consultant review, no formal complaints, and 15 minor adjustment suggestions to improve patient experience. A relationship was found between intra-articular injuries and lower patient satisfaction scores (p = 0.025), however no relationship was found between PRWE scores and the nature of the fracture. Also, no relationship was found between the type of immobilization and the functional outcome or patient satisfaction. Cost analysis of the self-care pathway V traditional pathway showed a cost savings of over £13,500 per year with the new self-care model compared to the traditional model. Conclusion Our study supports a VFC self-care pathway for patients with minimally displaced distal radius fractures. The pathway provides a good level of patient satisfaction and function. To improve the service, we will make minor amendments to our patient information sheet. Cite this article: Bone Jt Open 2022;3(9):726–732.

Published: September 2022

The mid-infrared (MIR) band entangled photon source is vital for the next generation of quantum communication, quantum imaging, and quantum sensing. However, the current entangled states are mainly prepared in the visible or near-infrared bands. It is still lacking high-quality entangled photon sources in the MIR band. In this work, we optimize the poling sequence of lithium niobate to prepare two kinds of typical entangled states, the Hermit–Gaussian state and the comb-like entangled state at 3.2 µm. We have also calculated the photon pair rates and estimated the effect of fabrication resolution in the schemes. Our approach will provide entangled photon sources with excellent performance for the study of quantum information in the MIR band.

Published: September 2022

Background
Little is known about the impact of ostomy formation in inflammatory bowel disease patients on course of disease, psychological well-being, quality of life and working capacity.

Methods
We analyzed patients over a follow-up of up to 16 years in the Swiss inflammatory bowel disease cohort study (SIBDCS) with prospective data collection. We compared Ulcerative colitis and Crohn’s disease patients with and without ostomy as well as permanent and closed stoma formation before and after surgery, investigating disease activity, psychological wellbeing and working capacity in a case-control design.

Results
Of 3825 SIBDCS patients, 176 with ostomy were included in the study and matched with 176 patients without ostomy using propensity score, equaling 352 patients for the analysis. As expected, we observed a lower mean and maximal disease activity in patients after stoma surgery compared with control patients without stoma. Overall, psychological wellbeing in patients with stomas vs. controls as well as patients with permanent vs. closed stoma was similar in terms of disease-specific quality of life (total score of the Inflammatory Bowel Disease Quality of Life questionnaire), psychological distress (total score of the Hospital Anxiety and Depression Scale), and stress at work (effort-reward-imbalance ratio), with the exception of a higher Posttraumatic Diagnostic Scale total score in patient with vs. without stoma. Compared to IBD patients without stoma, the adverse impact on working capacity in overall stoma IBD patients appeared to be modest. However we observe a significantly higher reduction in working capacity in permanent vs. closed stoma in CD but not UC patients.

Conclusion
As to be expected, IBD patients may benefit from closed and permanent stoma application. Stoma surgery appears to only modestly impact working capacity. Importantly, stoma surgery was not associated with adverse psychological outcomes, with comparable psychological well-being regardless of presence and type of stoma.
Accuracy of vertical cup-to-disc ratio discrimination among clinical optometry trainees with different years of clinical experience
Authors: Hairol Mohd Izzuddin , Lee Yun Rou 
Published: September 2022

Purpose
Accurate evaluation of the cup-to-disc ratio is crucial for optometrists and may be influenced by their clinical experience. The study’s objective was to compare the thresholds for discriminating vertical cup-to-disc ratio (VCDR) between years 2, 3, and 4 clinical optometry trainees.

Methods
One hundred fundus photos with various VCDR sizes were selected from a clinic database. The median VCDR (0.43) photo was assigned as the standard, while the other 99 were assigned as the test photos. The participant’s task was to discriminate using a 2-alternate-forced-choice paradigm whether the test photos’ VCDR were larger or smaller than the standard VCDR. Data were fit with a Weibull function, and three discrimination thresholds were determined: the point of subjective equality (PSE), the range of VCDR uncertainty, and the ability to judge VCDR that was 0.1 unit larger than the standard photo.

Results
Year 4 trainees had better VCDR discrimination thresholds. However, the difference between the three participant groups was not statistically different for all measurements (PSE: F(2,27) = 0.43, p = 0.657; VCDR uncertainty range: F(2,27) = 0.12, p = 0.887), and thresholds for correctly discriminating VCDR 0.1 larger than the standard photo’s VCDR: F(2,27) = 0.69, p = 0.512).

Conclusion
Although Year 4 optometry trainees performed slightly better at estimating VCDR than their Year 3 and Year 2 peers, the number of years of clinical experiences did not significantly affect their VCDR discrimination thresholds when 2-dimensional fundus photos were used as stimuli.

Authors: Dong Elizabeth Y. , Giap Andrew Q. , Lustigova Eva , Wu Bechien U. 
Published: September 2022

INTRODUCTION
Family history of gastric cancer has been shown as an independent risk factor of gastric cancer development and is associated with increased risk of progression to gastric cancer among patients with gastric intestinal metaplasia (GIM).

METHODS
Between 2017 and 2020, we conducted a prospective pilot screening program of patients with a confirmed first-degree relative with gastric cancer to evaluate the feasibility of screening and prevalence of precursor lesions (e.g., GIM or dysplasia) on biopsy.

RESULTS
A total of 61 patients completed screening by upper endoscopy with a mapping biopsy protocol: 27 (44%) were found to have GIM and 4 (7%) were found with low-grade dysplasia.

DISCUSSION
Our pilot screening program identified a high prevalence of precursor lesions for gastric cancer among asymptomatic patients with a first-degree relative with gastric cancer. Careful endoscopic inspection and standardized biopsy protocols may aid in prompt identification of these precursor lesions in those at risk of gastric cancer.

Abstract
The objective of this research is to produce and analyze natural fiber-based composites (sisal/polyester, kenaf/polyester, pineapple/polyester) and their hybrid composites (sisal/kenaf/polyester, kenaf/pineapple/polyester, and sisal/kenaf/pineapple/polyester) made by compression molding. These composites were characterized mechanically using hardness (shore D), tensile, flexural, and impact (Charpy) tests. Fiber matrix bonding was analyzed using Scanning Electron Microscopy (SEM). Among all the fiber-based samples (sisal/polyester, kenaf/polyester, and pineapple/polyester), sisal/polyester shows a high hardness value of 93.24 Sd, a tensile strength of 43.00 MPa, and an impact strength around 7.42 kJ/m2, while pineapple/polyester produces a better flexural strength of 83.21 MPa. Hybrid composites showed improved mechanical performance. The mechanical characteristics of the sisal/kenaf/pineapple/polyester hybrid composite were 56.16 MPa, 1.71 GPa, and 9.34 kJ/m2. The highest flexural strength of the Sisal/kenaf/polyester multi-layered samples was observed as 83.24 MPa.

Published: September 2022

Abstract
In this work, new polymeric aniline-barium ferrite and aniline-strontium ferrite thin layers were synthesized. In the first step, hexaferrites nano-additives were prepared by applying ultra-sound and microwave irradiation. Then, hexaferrites were added to aniline electrolyte solution separately. The electrodeposition of aniline as a polymeric matrix and hexaferrite as nano-additives was performed in an electrochemical cell in the presence of various acids. Scanning electron microscopy images were applied for morphology investigation and measuring average particle size. Energy dispersive X-ray spectroscopy was applied for elemental detection and analysis, as well as presence confirmation of nanoparticles. Atomic force microscopy was applied for surface roughness analysis of thin films. Magnetic property of the nanoparticles and polymeric nanocomposites was checked and measured by vibrating sample magnetometer. The crystallinity, crystallite size, and phase of samples were confirmed by X-ray diffraction pattern analysis.

Published: September 2022

Abstract
Essential oils obtained from medicinal plants show high therapeutic potential against several types of pathologies, including Alzheimer’s disease. The purpose of this work was to study the chemical composition and anticholinesterase inhibitory activity of the essential oil obtained from Lepisanthes rubiginosa leaves collected from Malaysia. Twenty-four components were identified using gas chromatography-flame ionization detection (GC-FID) and gas chromatography/mass spectrometry (GC-MS), which represent 99.5% of the essential oil. The identified major components include α-cadinol (40.0%), safrole (12.6%), α-amorphene (9.5%), (E)-isosafrole (5.0%), δ-cadinene (4.2%), and t-muurolol (4.1%). Anticholinesterase activity was assessed using Ellman method, and the essential oil demonstrated a moderate inhibitory activity against acetylcholinesterase (I%: 75.2%) and butyrylcholinesterase (I%: 70.2%) at conconcetration of 1000 μg/mL. The current study is the first to report chemical composition and anticholinesterase activity of the essential oil obtained from L. rubiginosa, which may have implications on the characterization, pharmaceutical, and therapeutic applications of Lepisanthes genus essential oils.
