Authors: Zhao Chenjing , Yu Meiwen , Cheng Xianfeng , Li Suo , Feng Suying 
Published: January 2024

Abstract

Background
The mechanism of livedoid vasculopathy (LV) remains unknown.

Objectives
To investigate the association between coagulation factors and LV and to assess the efficacy and safety of rivaroxaban in the treatment of patients with LV.

Methods
From May 2019 to July 2022, 89 patients with LV and 35 healthy controls were included in a cross-sectional cohort to measure the levels of coagulation factors. In addition, 55 patients with LV treated with rivaroxaban were included in a treatment cohort to assess the complete remission rate of ulcers (n = 44) and retiform purpura (n = 11) within 12 weeks.

Results
In the cross-sectional cohort, the activities of coagulation factor X in patients with LV were significantly higher than those in healthy controls: median 110.5% [interquartile range (IQR) 97.5–127.0%] vs. 101.3% (IQR 91.6–115.6); P = 0.05. In addition, coagulation factor X activities in the progressive stage were higher than at the stable stage: median 111.6% (IQR 102.3–132.5) vs. 105.4% (IQR 92.9–118.8); P = 0.04. Moreover, coagulation factor X activities were higher at the progressive stage than at the stable stage in a subgroup of 20 patients with LV (P = 0.04). In the treatment cohort taking rivaroxaban, 91% (40/44) of patients with ulcers achieved complete remission within 12 weeks, and 73% (8/11) of patients with retiform purpura achieved complete remission within 12 weeks. Mild side-effects occurred in 25% of patients (14/55), including menorrhagia (n = 10), gingival bleeding (n = 3) and haemorrhage (n = 1).

Conclusions
Coagulation factor X was associated with the incidence and severity of LV in this study. In addition, rivaroxaban was an effective and safe treatment for ulcers and retiform purpura in people with LV.
The historical demography of the Martha’s Vineyard signing community
Authors: Power Justin M , Meier Richard P 
Published: January 2024

Abstract
The deaf population of Martha’s Vineyard has fascinated scholars for more than a century since Alexander Graham Bell’s research on the frequent occurrence of deafness there and since Groce’s book on the island’s signing community (Groce, N. E. (1985). Everyone here spoke sign language: Hereditary deafness on Martha’s Vineyard. Cambridge, MA: Harvard University Press.). In Groce’s work, and in that of subsequent scholars, the Vineyard signing community has often been portrayed as remote and outlying, having developed independently of mainland signing communities for roughly 133 years until 1825. We re-examine that interpretation in light of historical, demographic, and genealogical evidence covering the period 1692–2008. We argue that the Vineyard signing community began in Chilmark in 1785, 93 years later than previously thought, and that it had had a brief period of independent development, roughly 40 years, before becoming well connected, through deaf education, to the nascent New England signing community. We consider the implications of the Vineyard community’s history for our understanding of how village signing communities develop.

Authors: Ikeoka Kuniyasu , Nishi Hiroyuki , Ueda Yasunori , Yamane Haruya , Matsumura Yasushi 
Published: January 2024

Abstract

Background
Thoracic endovascular aortic repair (TEVAR) has been widely introduced. However, unestablished transfemoral approach due to true lumen obliteration disables endovascular option.

Case summary
A 74-year-old male with a history of 15-year-ago type B aortic dissection presented with chronic bilateral lower extremity claudication. CT angiography revealed that a large entry tear was located at distal to the left subclavian artery. The thoracic aneurysmal degeneration progressed and eventually required repair. True lumen of infrarenal aorta to bilateral common iliac arteries was totally collapsed by false lumen, and the re-entry tear was open at external iliac artery. Initially, we performed recanalization to the collapsed true lumen. Bidirectional approach was taken from right brachial and bifemoral arteries. The covered endovascular reconstruction of aortic bifurcation (CERAB) technique and double D-shape moulding technique (DDMT) was performed to create covered stent configuration. As secondary treatment, 1-debranching TEVAR with axillary artery bypass was successfully performed by utilizing femoral approach.

Discussion
This case demonstrated feasibility of two-stage endovascular therapy for thoracic aneurysmal degeneration concomitant with true lumen obliteration. This combined technique of CERAB and DDMT was absolutely effective to minimize type Ⅲ endoleak in infrarenal segment. Hybrid endovascular treatment offered minimally invasive therapy to the patient.
Fructose intake from sugar-sweetened beverages is associated with a greater risk of hyperandrogenism in women: UK Biobank cohort study
Authors: Chen Huadong , Buziau Amée M , Rentería Miguel E , Simons Pomme I H G , Brouwers Martijn C G J 
Published: January 2024

Abstract

Objective
To assess the association between fructose consumption and serum sex hormone–binding globulin (SHBG), (free) testosterone, and risk of hyperandrogenism in a population-based cohort.

Design
An observational and genetic association study in participants of the UK Biobank (n = 136 384 and n = 383 392, respectively).

Methods
We assessed the relationship of (1) the intake of different sources of fructose (ie, total, fruit, fruit juice, and sugar-sweetened beverages [SSBs]) and (2) rs2304681 (a missense variant in the gene encoding ketohexokinase, used as an instrument of impaired fructose metabolism), with SHBG, total and free testosterone levels, and risk of hyperandrogenism (free androgen index &gt;4.5).

Results
The intake of total fructose and fructose from fruit was associated with higher serum SHBG and lower free testosterone in men and women and lower risk of hyperandrogenism in women. In contrast, fructose intake from SSB (≥10 g/day) was associated with lower SHBG in men and women and with higher free testosterone levels and risk of hyperandrogenism in women (odds ratio [OR]: 1.018; 95% confidence interval [CI]: 1.010; 1.026). Carriers of the rs2304681 A allele were characterized by higher circulating SHBG (both men and women), lower serum free testosterone (women), and a lower risk of biochemical hyperandrogenism (OR: 0.997, 95% CI: 0.955; 0.999; women) and acne vulgaris (OR: 0.975, 95% CI: 0.952; 0.999; men and women combined).

Conclusions
The consumption of ≥10 g/day fructose from SSB, corresponding to ≥200 mL serving, is associated with a 2% higher risk of hyperandrogenism in women. These observational data are supported by our genetic data.

Published: January 2024

Abstract

Aims
Data on the optimal use of antithrombotic drugs and associated clinical outcomes in patients with atrial fibrillation (AF) and acute ischaemic stroke (IS) are limited. We investigated the prescription patterns of antithrombotics in community practice and long-term clinical prognosis according to early post-stroke antithrombotic therapy in patients with AF and acute IS.

Methods and results
Patients with AF who were admitted for acute IS at a single tertiary hospital in 2010–2020 were retrospectively reviewed. Clinical profiles including the aetiology of stroke and prescription patterns of antithrombotics were identified. The net clinical outcome (NCO)—the composite of recurrent stroke, any bleeding, hospitalization or emergency department visits for cardiovascular (CV) events, and death—was compared according to the antithrombotic therapy at the first outpatient clinic visit [oral anticoagulation (OAC) alone vs. antiplatelet (APT) alone vs. OAC/APT(s)] following discharge. A total of 918 patients with AF and acute IS (mean age, 72.6 years; male, 59.3%; mean CHA₂DS₂-VASc score 3.3) were analysed. One-third (33.9%, n = 310) of patients were simultaneously diagnosed with AF and IS. The most common aetiology of IS was cardioembolism (71.2%), followed by undetermined aetiology (19.8%) and large artery atherosclerosis (6.0%). OAC, APT(s), and concomitant OAC and APT(s) were prescribed in 33.4%, 11.1%, and 53.4% of patients during admission that changed to 67.0%, 9.1%, and 21.7% at the first outpatient clinic, and were mostly continued up to one year after IS. Non-prescription of OAC was observed in 11.3% of post-stroke patients with AF. During a median follow-up of 2.1 years, the overall incidence rate of NCO per 100 patient-year (PY) was 20.14. APT(s) monotherapy presented the highest cumulative risk of NCO (adjusted hazard ratio 1.47, 95% confidence interval 1.08–2.00, P = 0.015; with reference to OAC monotherapy) mainly driven by the highest rates of recurrent stroke and any bleeding. OAC/APT(s) combination therapy was associated with a 1.62-fold significantly higher risk of recurrent stroke (P = 0.040) and marginally higher risk of any bleeding than OAC monotherapy.

Conclusion
Approximately one-third of acute IS in AF have a distinctive mechanism from cardioembolism. Although APT was frequently prescribed in post-stroke patients with AF, no additive clinical benefit was observed. Adherence to OAC treatment is essential to prevent further CV adverse events in patients with AF and IS.
A pilot study of the quality of care of atrial fibrillation in Irish general practice
Authors: McErlean Sarah , Broughan John , McCombe Geoff , Fawsitt Ronan , Ledwidge Mark , Cullen Walter , Gallagher Joe 
Published: January 2024

Abstract

Background
Worldwide, atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in adults and poses a significant burden to patients, physicians, and healthcare systems. We developed a quality of care score based on the Atrial Fibrillation Better Care pathway recommended by the European Society of Cardiology and the European Heart Rhythm Association guidelines. This is a 14-point score that we have termed the MAGIC score(Management of Atrial Fibrillation in Integrated Care and General Practice).

Objective
The objective of this pilot study was to develop and test a quality of care score for patients with permanent AF in general practice.

Methods
An observational cross-sectional pilot study was undertaken. Proportionate sampling was used across 11 practices from the Ireland East practice-based research network. The GPs completed a report form on each patient by undertaking a retrospective chart review. Eleven practices participated with a total of 1855 patients with AF. We received data on 153 patients.

Results
The main findings were that no patient met all 14 guideline based recommendations. The mean MAGIC score was 11.3. Points were most commonly deducted because the creatinine clearance and HAS-BLED score were not recorded, and the patient was not on the correct dose of oral anti-coagulation.

Conclusion
This study demonstrates the feasibility of using a quality of care score to measure the quality of AF management in general practice. This scoring system, which is based on internationally recognized quality of care markers, highlights key areas that can be targeted with quality improvement intervention.

Abstract
Mutations in SETD2 are among the most prevalent drivers of renal cell carcinoma (RCC). We identified a novel single nucleotide polymorphism (SNP) in SETD2, E902Q, within a subset of RCC patients, which manifests as both an inherited or tumor-associated somatic mutation. To determine if the SNP is biologically functional, we used CRISPR-based genome editing to generate the orthologous mutation within the Drosophila melanogaster Set2 gene. In Drosophila, the homologous amino acid substitution, E741Q, reduces H3K36me3 levels comparable to Set2 knockdown, and this loss is rescued by reintroduction of a wild-type Set2 transgene. We similarly uncovered significant defects in spindle morphogenesis, consistent with the established role of SETD2 in methylating α-Tubulin during mitosis to regulate microtubule dynamics and maintain genome stability. These data indicate the Set2 E741Q SNP affects both histone methylation and spindle integrity. Moreover, this work further suggests the SETD2 E902Q SNP may hold clinical relevance.
Asymptotic properties of the Lotka–Volterra competition and mutualism model under stochastic perturbations
Authors: Shaikhet Leonid , Korobeinikov Andrei 
Published: January 2024

Abstract
Stochastically perturbed models, where the white noise type stochastic perturbations are proportional to the current system state, the most realistically describe real-life biosystems. However, such models essentially have no equilibrium states apart from one at the origin. This feature makes analysis of such models extremely difficult. Probably, the best result that can be found for such models is finding of accurate estimations of a region in the model phase space that serves as an attractor for model trajectories. In this paper, we consider a classical stochastically perturbed Lotka–Volterra model of competing or symbiotic populations, where the white noise type perturbations are proportional to the current system state. Using the direct Lyapunov method in a combination with a recently developed technique, we establish global asymptotic properties of this model. In order to do this, we, firstly, construct a Lyapunov function that is applicable to the both competing (and globally stable) and symbiotic deterministic Lotka–Volterra models. Then, applying this Lyapunov function to the stochastically perturbed model, we show that solutions with positive initial conditions converge to a certain compact region in the model phase space and oscillate around this region thereafter. The direct Lyapunov method allows to find estimates for this region. We also show that if the magnitude of the noise exceeds a certain critical level, then some or all species extinct via process of the stochastic stabilization (‘stabilization by noise’). The approach applied in this paper allows to obtain necessary conditions for the extinction. Sufficient conditions for the extinction (that for this model occurs via the process that is known as the ‘stochastic stabilization’, or the ‘stabilization by noise’) are found applying the Khasminskii-type Lyapunov functions.
IL-17 and IFN-γ–producing Respiratory Tissue-Resident Memory CD4 T Cells Persist for Decades in Adults Immunized as Children With Whole-Cell Pertussis Vaccines
Authors: McCarthy Karen N , Hone Stephen , McLoughlin Rachel M , Mills Kingston H G 
Published: January 2024

Abstract
The objective was to determine if antigen-specific tissue-resident memory T (TRM) cells persist in respiratory tissues of adults immunized as children with whole-cell pertussis (wP) or acellular pertussis (aP) vaccines. Mononuclear cells from tonsil or nasal tissue cells were cultured with Bordetella pertussis antigens and TRM cells quantified by flow cytometry. Adults immunized with wP vaccines as children had significantly more interleukin 17A (IL-17A) and interferon-γ (IFN-γ)–producing TRM cells that respond to B. pertussis antigens in respiratory tissues when compared with aP-primed donors. Our findings demonstrate that wP vaccines induce CD4 TRM cells that can persist in respiratory tissues for decades.

Authors: Kwan Brian , Bell John F , Longhurst Christopher A , Goldhaber Nicole H , Clay Brian 
Published: January 2024

Abstract

Objectives
Effective communication amongst healthcare workers simultaneously promotes optimal patient outcomes when present and is deleterious to outcomes when absent. The advent of electronic health record (EHR)-embedded secure instantaneous messaging systems has provided a new conduit for provider communication. This manuscript describes the experience of one academic medical center with deployment of one such system (Secure Chat).

Methods
Data were collected on Secure Chat message volume from June 2017 to April 2023. Significant perideployment events were reviewed chronologically.

Results
After the first coronavirus disease 2019 lockdown in March 2020, messaging use increased by over 25 000 messages per month, with 1.2 million messages sent monthly by April 2023. Comparative features of current communication modalities in healthcare were summarized, highlighting the many advantages of Secure Chat.

Conclusions
While EHR-embedded secure instantaneous messaging systems represent a novel and potentially valuable communication medium in healthcare, generally agreed-upon best practices for their implementation are, as of yet, undetermined.

Abstract
Hip areal BMD (aBMD) is widely used to identify individuals with increased fracture risk. Low aBMD indicates low strength, but this association differs by sex with men showing greater strength for a given aBMD than women. To better understand the structural basis giving rise to this sex-specific discrepancy, cadaveric proximal femurs from White female and male donors were imaged using nano-CT and loaded in a sideways fall configuration to assess strength. FN pseudoDXA images were generated to identify associations among structure, aBMD, and strength that differ by sex. Strength correlated significantly with pseudoDXA aBMD for females (R2 = 0.468, P &lt; .001) and males (R2 = 0.393, P &lt; .001), but the elevations (y-intercepts) of the linear regressions differed between sexes (P &lt; .001). Male proximal femurs were 1045 N stronger than females for a given pseudoDXA aBMD. However, strength correlated with pseudoDXA BMC for females (R2 = 0.433, P &lt; .001) and males (R2 = 0.443, P &lt; .001) but without significant slope (P = .431) or elevation (P = .058) differences. Dividing pseudoDXA BMC by FN-width, total cross-sectional area, or FN-volume led to significantly different associations between strength and the size-adjusted BMC measures for women and men. Three structural differences were identified that differentially affected aBMD and strength for women and men: First, men had more bone mass per unit volume than women; second, different cross-sectional shapes resulted in larger proportions of bone mass orthogonal to the DXA image for men than women; and third, men and women had different proportions of cortical and trabecular bone relative to BMC. Thus, the proximal femurs of women were not smaller versions of men but were constructed in fundamentally different manners. Dividing BMC by a bone size measure was responsible for the sex-specific associations between hip aBMD and strength. Thus, a new approach for adjusting measures of bone mass for bone size and stature is warranted.

Published: January 2024

Abstract

Objectives:
The purpose of this study was to present a systematic review of the health-related problems of factory workers in the textile and fashion industry. These workers endure long sitting postures, poor workspace conditions, and long working hours to complete their overload of tasks. This situation results in several health problems that affect the productivity, mental health, and well-being of the workers.

Methods:
The relevant data (21 article publications) were obtained from the Scopus database. Analysis of the 21 articles was grouped under 3 research themes based on the critical reading of the content and abstracts: respiratory problems, musculoskeletal disorders, and psychological stressors and other health issues.

Results:
The findings show that factory workers are exposed to dust particles of cotton and other raw materials, fumes, and chemicals from manufacturing processes. This prolonged exposure without the use of personal protective equipment (PPE) leads to respiratory diseases like byssinosis that affect the workers’ health. Additionally, working in a particular posture due to the workstation design for prolonged hours causes musculoskeletal disorders or pains. Workers also suffer from anxiety, depression, and stress from workload and pressure, hence making them unstable with reduced productivity.

Conclusions:
The findings of the study reinforce the need for a safe workspace and spacious work environment, provision of PPE, training in occupational hazards, frequent health checks, and ergonomic assessment of workstations to reduce prolonged work postures. Stakeholders, employers, policymakers, and governments should collaborate to safeguard and protect the well-being and health of the workers at these factories.
An unusual case of pilonidal p16 positive squamous cell carcinoma—a case report
Authors: Khatri Hershil , Chuang Tzu-Yi , Swan Daniel 
Published: January 2024

Abstract
Basaloid squamous cell carcinoma (BSCC) is a rare and aggressive variant of squamous cell carcinoma. It is commonly seen in the oropharynx and strongly associated with p16-expressivity and high-risk human papilloma virus (HPV). We report the first case of primary cutaneous p16-positive BSCC in an elderly woman, with a background of chronic inverse psoriasis of the natal cleft. P16-expressivity is a common surrogate marker for oncogenic HPV16, routinely tested for oropharyngeal/anogenital squamous cell carcinoma. This is not routinely done for primary cutaneous disease. Pilonidal disease is uncommon in the elderly population, and malignant transformation is rarer still. Surgical resection is considered the mainstay of treatment for primary cutaneous BSCC, however due to this patient’s broad distribution of cutaneous field change and p16-expressivity, she was effectively treated with primary radiotherapy. This is a unique case of malignant transformation of pilonidal disease in an atypical demographic, with a rare/aggressive disease variant.
