Published: August 2024

Abstract

Background
Patients with Crohn’s disease (CD) or ulcerative colitis (UC) often cycle through conventional therapies (CT) with different mechanisms of action (MOA) before initiating advanced therapy (AT). We describe treatment patterns among patients with CD/UC.

Methods
Using Merative MarketScan Research databases, adult patients with CD/UC were identified from medical/pharmacy claims (2017–2021). Patients had ≥1 hospitalization or ≥2 outpatient visits (≥30 days apart within 1 year) for CD/UC. Two cohorts were established; cohort 1: Newly diagnosed patients (index date is the date of first diagnosis) and cohort 2: Patients initiating AT (index date is the date of first AT). First-line treatment patterns (cohort 1) and CT pathways before AT initiation (cohort 2) by the number of episodes (ie, adding a new therapy, switching to another therapy, or restarting the same therapy after ≥60 days) and MOA are reported.

Results
Among newly diagnosed patients in cohort 1 (CD: n = 1739; UC: n = 2740), 14.4% (CD) and 5.9% (UC) of patients had any AT use during the follow-up period (mean: 2.3 years; ≥ 77% initiated corticosteroids). Among patients in cohort 2 (CD: n = 2594; UC: n = 2431), the mean number of CT episodes before AT initiation was 4.0 ± 4.3 (CD) and 5.9 ± 5.0 (UC). Among those with ≥1 corticosteroid episode (CD: 82.2%; UC: 91.5%), the mean number of episodes was 4.6 ± 4.3 (CD) and 6.3 ± 5.0 (UC). Overall, 13.3% (CD) and 23.7% (UC) of patients cycled through 3 MOAs before AT initiation.

Conclusions
Despite treatment recommendations, few newly diagnosed CD/UC patients initiated AT as their first treatment. Moreover, patients cycled through multiple CTs before initiating AT.

Abstract

Aims
The development of cell therapy as a widely available clinical option for ischaemic cardiomyopathy is hindered by the invasive nature of current cell delivery methods. Furthermore, the rapid disappearance of cells after transplantation provides a cogent rationale for using repeated cell doses, which, however, has not been done thus far in clinical trials because it is not feasible with invasive approaches. The goal of this translational study was to test the therapeutic utility of the intravenous route for cell delivery.

Methods and results
Pigs with chronic ischaemic cardiomyopathy induced by myocardial infarction received one or three intravenous doses of allogeneic bone marrow mesenchymal stromal cells (MSCs) or placebo 35 days apart. Rigour guidelines, including blinding and randomization, were strictly followed. A comprehensive assessment of left ventricular (LV) function was conducted with three independent methods (echocardiography, magnetic resonance imaging, and haemodynamic studies). The results demonstrate that three doses of MSCs improved both load-dependent and independent indices of LV function and reduced myocardial hypertrophy and fibrosis; in contrast, one dose failed to produce most of these benefits.

Conclusions
To our knowledge, this is the first study to show that intravenous infusion of a cell product improves LV function and structure in a large animal model of chronic ischaemic cardiomyopathy and that repeated infusions are necessary to produce robust effects. This study, conducted in a clinically relevant model, supports a new therapeutic strategy based on repeated intravenous infusions of allogeneic MSCs and provides a foundation for a first-in-human trial testing this strategy in patients with chronic ischaemic cardiomyopathy.
Case report: intravascular ultrasound-guided entry to an anomalous highly angulated circumflex coronary artery originating from the right sinus of Valsalva
Authors: Yao Zhihong , Khalatbari Afshin , Khand Aleem 
Published: August 2024

Abstract

Background
Anomalous coronary arteries originating from the contralateral sinus of Valsalva constitute a rare congenital anomaly. Most of such anomalous coronary arteries exhibit slit-like orifice that are often compounded by external compressive factors. Consequently, percutaneous coronary intervention (PCI) of these vessels poses considerable challenges, both in terms of cannulation but also intervention in often acutely angulated vessels.

Case summary
A 61-year-old man, with a history of previous coronary artery bypass graft surgery and PCI presented with a history consistent with unstable angina. Notably, the left circumflex artery (LCX) in this individual exhibited an anomalous origin. Due to unfavourable anatomy and ambiguous LCX ostium take-off, previous operators had elected PCI of the saphenous vein graft (SVG) anastomosed to the obtuse marginal branch. A computed tomography scan on this occasion confirmed occlusion of the SVG and defined precise origin of anomalous coronary artery. Real-time live intravascular ultrasound (IVUS) positioned in the ascending aorta, in the right sinus of Valsalva, allowed visualization of the origin and wiring of the anomalous circumflex coronary artery and also facilitated successful PCI.

Discussion
As far as we are aware, this is the first description of IVUS assisted wiring of an anomalous coronary artery. Intravascular ultrasound also facilitated decision making in this complex angioplasty of an angulated and heavily diseased circumflex coronary artery.

Abstract

Aims
Female physicians are underrepresented in invasive electrophysiology (EP) for multiple reasons. Despite an increasing focus on the topic, it is unclear what aspects are predominant.

Methods and results
We conducted a survey on career paths of current or former EP fellows in Germany to elucidate how gender and family affected their careers. 231 fellows (24.2% female) were invited. 110 participants completed the survey (30.9% female, mean age 41.0 ± 5.0 years, and 79.1% with children). Female and male participants with children reported similar career goals and achievements before parenthood, but afterwards women changed their career paths more often. Major reasons were personal priorities followed by lack of flexibility at work and at home. Women covered the majority of childcare. At the time of the survey, 80.0% of women and 96.4% of men with a former career goal of invasive EP were active in invasive EP. Independent of age, women were in lower-level positions, had accomplished fewer professional achievements, were less satisfied with their work and had fewer children. 56.5% of women did not feel supported by their employers regarding family issues. 82.6% reported there was no satisfactory day care. 69.6% were unable to continue to follow their career during pregnancy, mostly due to restrictions by employers (75.0%). Dedicated policies for pregnant workers or support programmes were scarce.

Conclusion
Beside the distribution of childcare at home, lack of flexibility and support by employers as well as working and fluoroscopy restrictions during pregnancy hamper women in EP and should be addressed.

Abstract

Background
The coronavirus disease 2019 (COVID-19) pandemic impacted cancer services worldwide. We examined the effect of the first three pandemic waves on the number of electronic (e)-referrals to rapid access clinics (RACs) for breast, lung and prostate cancer in Ireland.

Methods
This study used a retrospective, repeated cross-sectional design. The predicted weekly number of e-referrals by suspected cancer types from March 2020 to May 2021 was calculated using the Holt-Winters seasonal smoothing method, based on the observed numbers from a representative pre-pandemic period (01 January 2019 to 01 March 2020) and compared this with the observed number across the first three pandemic waves (02 March 2020 to 09 May 2021). Percentage differences were calculated between observed and predicted numbers of e-referrals for the three RACs and patterns were examined in each wave.

Results
Observed e-referrals were lower than predicted for all three RACs in the first wave of the pandemic (15.7% lower for breast, 39.5% lower for lung and 28.1% lower for prostate) with varying levels of recovery in the second and third waves for the three e-referral types.

Conclusions
The COVID-19 pandemic impacted patterns of e-referrals to RACs in the first three pandemic waves in Ireland. Early identification of changes in engagement with health services, such as a decrease in primary care presentations with a resultant decrease in e-referrals to RACs can allow for a rapid response from cancer control programmes. Continued surveillance of the impact of service disruption on cancer services allows policy makers and strategic leaders in cancer control programmes to respond rapidly to mitigate the impact on cancer outcomes.
Point-of-care ultrasound to assess left ventricular ejection fraction in heart failure in unselected patients in primary care: a systematic review

Published: August 2024

Abstract

Background
Heart failure (HF) is the most frequent cardiovascular pathology in primary care. Echocardiography is the gold standard for diagnosis, follow-up, and prognosis of HF. Point-of-care ultrasound (POCUS) is of growing interest in daily practice.

Aim
This study aimed to systematically review the literature to evaluate left ventricular ejection fraction (LVEF) assessment of unselected patients in primary care by non-expert physicians with cardiac POCUS (cPOCUS).

Methods
We searched in Medline, Embase, and Pubmed up to January 2024 for interventional and non-interventional studies assessing LVEF with cPOCUS in unselected patients with suspected or diagnosed HF in hospital or outpatient settings, performed by non-expert physicians.

Results
Forty-two studies were included, involving 6598 patients, of whom 60.2% were outpatients. LVEF was assessed by 351 non-expert physicians after an initial ultrasound training course. The LVEF was mainly assessed by visual estimation (90.2%). The most frequent views were parasternal long/short axis, and apical 4-chamber. The median time of cPOCUS was 8 minutes. A strong agreement was found (κ = 0.72 [0.63; 0.83]) compared to experts when using different types of ultrasound devices (hand-held and standard), and agreement was excellent (κ = 0.84 [0.71; 0.89]) with the same device. Training course combined a median of 4.5 hours for theory and 25 cPOCUS for practice.

Conclusion
The use of cPOCUS by non-expert physicians after a short training course appears to be an accurate complementary tool for LVEF assessment in daily practice. Its diffusion in primary care could optimize patient management, without replacing specialist assessment.

Published: August 2024

Abstract
This study conducts an economic analysis to evaluate the impact of Swiss needle cast (SNC) caused by Nothophaeocryptopus gaeumannii on Douglas-fir (Pseudotsuga menziesii) plantations at the stand level in western Oregon. We examine timber and nontimber benefits across varying degrees of SNC severity considering timber benefits and carbon sequestration benefits. By comparing these values with unaffected Douglas-fir stands, our aim is to quantify the economic losses associated with SNC in terms of the land expectation values. The total land expectation value for a stand affected by SNC ranges from $556 to $2,179/ac, representing an average decrease of 50% ($1,066/ac) in economic revenues compared with a Douglas-fir stand without SNC infestation. Engaging in cost-effective annual management activities, with maximum costs of $43–$56/ac, could offset the profitability decline. On average, the total losses in profits for the current plantations affected by SNC are estimated to be around $206.5–430 million.
Study Implications: In this study, we examine the economic impacts of Swiss needle cast (SNC) on the profitability of western Douglas-fir in Oregon. Our results reveal that profits for landowners can be, on average, reduced by $1,066/ac when their stand is infested by SNC, representing a 50% loss in profitability. Landowners could potentially mitigate these losses by engaging in annual management activities aimed at preventing Douglas-fir infestation, incurring a cost ranging between $43–56/ac, which could offset the reduction in profitability.
Differential impacts of the COVID-19 pandemic on mental health service access among Medicaid-enrolled individuals
Authors: McConnell K John , Edelstein Sara , Wolk Courtney Benjamin , Lindner Stephan , Zhu Jane M 
Published: August 2024

Abstract
The COVID-19 public health emergency (PHE) caused significant disruptions in the delivery of care, with in-person visits decreasing and telehealth use increasing. We investigated the impact of these changes on mental health services for Medicaid-enrolled adults and youth in Washington State. Among enrollees with existing mental health conditions, the first year of the PHE was associated with a surge in specialty outpatient mental health visits (13% higher for adults and 7% higher for youth), returning to pre-PHE levels in the second year. Conversely, youth with new mental health needs experienced a decline in specialty outpatient visit rates by ∼15% and 37% in the first and second years of the PHE, respectively. These findings indicate that while mental health service use was maintained or improved for established patients, these patterns did not extend to Medicaid-enrolled youth with new mental health needs, potentially due to barriers such as difficulty in finding providers and establishing new patient-provider relationships remotely. To bridge this gap, there is a need for a multi-faceted approach that includes improving service accessibility, enhancing provider availability, and optimizing initial care encounters, whether in-person or virtual, to better support new patients.
Three Decades of Transitional Justice Practice in Africa: Reflections on Lessons Learnt Towards an African Transformative Justice
Authors: Moyo-Kupeta Annah 
Published: August 2024

ABSTRACT
The transitional justice field has shown great versatility in its response to the consequences of conflicts, dealing with human rights violations, addressing legacies of the past and tackling emerging issues and vulnerabilities. This editorial reflects on Africa’s three decades of implementing transitional justice with a focus on key lessons learnt and their contribution to the betterment of transitional justice offering on the continent. The editorial discusses an African transformative justice as codified in the African Union Transitional Justice Policy as responsive, resonant and contextually relevant to the lived realities on the continent. The editorial argues that the African Union Transitional Justice Policy is the embodiment of lessons learnt from transitional justice practice on the continent and demonstrates the adaptability and expansion of the frontiers of transitional justice to address emerging issues as well as both historical legacies and most recent violations.
The role of dendritic cells in the instruction of helper T cells in the allergic march
Authors: Kubo Masato , Harada Yasuyo , Sasaki Takanori 
Published: August 2024

Abstract
Allergy is a complex array of diseases influenced by innate and adaptive immunity, genetic polymorphisms, and environmental triggers. Atopic dermatitis is a chronic inflammatory skin disease characterized by barrier defects and immune dysregulation, sometimes leading to asthma and food allergies because of the atopic march. During atopic skin inflammation, Langerhans cells and dendritic cells (DCs) in the skin capture and deliver allergen information to local lymph nodes. DCs are essential immune sensors coordinating immune reactions by capturing and presenting antigens to T cells. In the context of allergic responses, DCs play a crucial role in instructing two types of helper T cells—type 2 helper T (Th2) cells and follicular helper T (TFH) cells—in allergic responses and IgE antibody responses. In skin sensitization, the differentiation and function of Th2 cells and TFH cells are influenced by skin-derived factors, including epithelial cytokines, chemokines, and signalling pathways to modify the function of migratory DCs and conventional DCs. In this review, we aim to understand the specific mechanisms involving DCs in allergic responses to provide insights into the pathogenesis of allergic diseases and potential therapeutic strategies.

Published: August 2024

Abstract
Young animals are highly susceptible to intestinal damage due to incomplete intestinal development, making them vulnerable to external stimuli. Weaning stress in piglets, for instance, disrupts the balance of intestinal microbiota and metabolism, triggering intestinal inflammation and resulting in gut damage. Caffeic acid (CA), a plant polyphenol, can potentially improve intestinal health. Here, we evaluated the effects of dietary CA on the intestinal barrier and microbiota using a lipopolysaccharide (LPS)-induced intestinal damage model. Eighteen piglets were divided into three groups: control group (CON), LPS group (LPS), and CA + LPS group (CAL). On the 21st and 28th day, six piglets in each group were administered either LPS (80 μg/kg body weight; Escherichia coli O55:B5) or saline. The results showed that dietary CA improved the intestinal morphology and barrier function, and alleviated the inflammatory response. Moreover, dietary CA also improved the diversity and composition of the intestinal microbiota by increasing Lactobacillus and Terrisporobacter while reducing Romboutsia. Furthermore, the LPS challenge resulted in a decreased abundance of 14 different bile acids and acetate, which were restored to normal levels by dietary CA. Lastly, correlation analysis further revealed the potential relationship between intestinal microbiota, metabolites, and barrier function. These findings suggest that dietary CA could enhance intestinal barrier function and positively influence intestinal microbiota and its metabolites to mitigate intestinal damage in piglets. Consuming foods rich in CA may effectively reduce the incidence of intestinal diseases and promote intestinal health in piglets.
Glucose inhibits the inflammatory response in goose fatty liver by increasing the ubiquitination level of PKA

Published: August 2024

Abstract
Protein kinase A (PKA) plays an important role in cellular life activities. Recently, PKA was found to bind to the inhibitor of nuclear factor-kappaB (IκB), a key protein in the nuclear factor-kappaB (NF-κB) pathway, to form a complex involved in the regulation of inflammatory response. However, the role of PKA in the anti-inflammatory of goose fatty liver is still unclear. A total of 14 healthy 70-d-old male Lander geese were randomly divided into a control group and an overfeeding group. Inflammation level was analyzed by histopathological method in the liver. The mRNA and protein abundance of PKA and tumor necrosis factor-alpha (TNFα), as well as the ubiquitination level of PKA, were detected. Moreover, goose primary hepatocytes were cotreated with glucose, harringtonine, and carbobenzoxy-l-leucyl-l-leucyl-l-leucinal (MG132). Finally, the co-immunoprecipitated samples of PKA from the control and overfeeding group were used for protein mass spectrometry. The results showed that no difference in PKA mRNA expression was observed (P &gt; 0.05), while the PKA protein level in the overfed group was significantly reduced (P &lt; 0.05) when compared with the control group. The ubiquitination level of PKA was higher than that of the control group in fatty liver. The mRNA expression of PKA was elevated but protein abundance was reduced in goose primary hepatocytes with 200 mmol/L glucose treatment (P &lt; 0.05). The PKA protein abundance was dramatically reduced in hepatocytes treated with harringtonine (P &lt; 0.01) when compared with the glucose-supplemented group. Nevertheless, MG132 tended to alleviate the inhibitory effect of harringtonine on PKA protein abundance (P = 0.081). There was no significant difference in TNFα protein level among glucose-treated groups and control (P &gt; 0.05). Protein mass spectrometry analysis showed that 29 and 76 interacting proteins of PKA were screened in goose normal and fatty liver, respectively. Validation showed that PKA interacted with the E3 ubiquitination ligases ring finger protein 135 (RNF135) and potassium channel modulatory factor 1 (KCMF1). In summary, glucose may inhibit the inflammatory response in goose fatty liver by increasing the ubiquitination level of PKA. Additionally, RNF135 and KCMF1 may be involved in the regulation of PKA ubiquitination level as E3 ubiquitination ligases.

Published: August 2024

Abstract
CRISPR/Cas9 manipulations are possible in many insects and ever expanding. Nonetheless, success in one species and techniques developed for it are not necessarily applicable to other species. As such, the development and expansion of CRISPR-based (clustered regularly interspaced short palindromic repeats) genome-editing tools and methodologies are dependent upon direct experimentation. One useful technique is Cas9-dependent homologous recombination, which is a critical tool for studying gene function but also for developing pest related applications like gene drive. Here, we report our attempts to induce Cas9 homology directed repair (HDR) and subsequent gene drive in Tribolium castaneum (Herbst; Insecta: Coleoptera: Tenebrionidae). Utilizing constructs containing 1 or 2 target gRNAs in combination with Cas9 under 2 different promoters and corresponding homology arms, we found a high incidence of CRISPR/Cas9 induced mutations but no evidence of homologous recombination. Even though the generated constructs provide new resources for CRISPR/Cas9 modification of the Tribolium genome, our results suggest that additional modifications and increased sample sizes will be necessary to increase the potential and detection for HDR of the Tribolium genome.
