Time and dose-dependent effect of systemic glucocorticoids on major adverse cardiovascular event in patients with rheumatoid arthritis: a population-based study.

OBJECTIVES: Cardiovascular event (CVE) risk in rheumatoid arthritis (RA) was increased by glucocorticoids (GC) use. Whether there is a threshold dose and duration of GC use beyond which will increase CVE rate remains controversial. We studied the time-varying effect of GC and its dose on the risk of incident major adverse cardiovascular events (MACE) in patients with RA. METHODS: Patients with RA without MACE at baseline were recruited from a Hong Kong citywide database from 2006 to 2015 and followed till 2018. The primary outcome was the first occurrence of an MACE. Cox regression and inverse probability treatment weighting analyses with time-varying covariates were used to evaluate the association of GC and MACE, adjusting for demographics, traditional CV risk factors, inflammatory markers and the usage of antirheumatic drugs. RESULTS: Among 12 233 RA patients with 105 826 patient-years of follow-up and a mean follow-up duration of 8.7 years, 860 (7.0%) developed MACE. In the time-varying analyses after controlling for confounding factors, a daily prednisolone dose of ≥5 mg significantly increased the risk of MACE (erythrocyte sedimentation rate model: HR 2.02, 95% CI 1.72 to 2.37; C reactive protein model: HR 1.87, 95% CI 1.60 to 2.18), while a daily dose below 5 mg was not associated with MACE risk, compared with no GC use. In patients receiving daily prednisolone ≥5 mg, the risk of incident MACE was increased by 7% per month. CONCLUSIONS: GC was associated with a duration and dose-dependent increased risk of MACE in patients with RA. Very low dose prednisolone (<5 mg daily) did not appear to confer excessive CV risk.

Five-year cardiovascular event risk in early rheumatoid arthritis patients who received treat-to-target management: a case-control study.

OBJECTIVES: This study explored whether the excess cardiovascular (CV) disease (CVD) risk in RA could be ameliorated by suppression of inflammation using a treat-to-target (T2T) approach. We compared the CV event (CVE) incidence among ERA patients managed by a T2T strategy with a CV risk factor-matched non-RA population and a historical RA cohort (HRA). METHODS: This was an observational study using the city-wide hospital data and the ERA registry. ERA patients received T2T management while HRA patients received routine care. Each ERA/HRA patient was matched to three non-RA controls according to age, gender and CV risk factors. Patients on antiplatelet/anticoagulant agents, with pre-existing CVD, chronic kidney disease or other autoimmune diseases were excluded. All subjects were followed for up to 5 years. The primary end point was the first occurrence of a CVE. RESULTS: The incidence of CVE in the ERA cohort (n = 261) and ERA controls were similar with a hazard ratio of 0.53 (95% CI 0.15, 1.79). In contrast, the incidence of CVE in the HRA cohort (n = 268) was significantly higher than that of the HRA controls with a hazard ratio of 1.9 (95% CI 1.16, 3.13). The incidence of CVE in the ERA cohort was significantly lower than that of the HRA cohort and the difference became insignificant after adjusting for inflammation, the use of methotrexate and traditional CV risk factors. CONCLUSION: ERA patients managed by a T2T strategy did not develop excess CVE compared with CV risk factor-matched controls over 5 years.

Successful Design and Implementation of a POEM Program for Achalasia in an Integrated Healthcare System.

BACKGROUND: Per Oral Endoscopic Myotomy (POEM) is a minimally invasive treatment for achalasia with results comparable to laparoscopic Heller myotomy (LHM). Studies have described the development of proficiency for endoscopists learning to perform POEM, and societies have defined educational and technical objectives for advanced endoscopy fellows in training. However, there is limited guidance on the organizational strategy and educational plan necessary to develop an achalasia service with POEM expertise. AIMS: We aim to outline the steps for design and implementation of a successful POEM program. METHODS: We reported our experience developing a multi-disciplinary clinical program for POEM and the steps taken to achieve procedural proficiency. We also reported our technical success (successful tunneling into the gastric cardia and myotomy of LES muscle fibers) and clinical success (post-procedure Eckardt score ≤ 3) at 3-6 months and 12 months post-procedure. Adverse events were classified per the ASGE lexicon for endoscopic adverse events. RESULTS: After creating a multi-disciplinary clinical program for achalasia and completing procedural proficiency for POEM, our technical success rate was 100% and clinical success rate 90% for the first 41 patients. One adverse event (2.4%) occurred, moderate in severity per the American Society of Gastrointestinal Endoscopy (ASGE) lexicon for adverse endoscopic events. CONCLUSION: In this study, we outlined the steps involved to establish a POEM service in a large integrated healthcare system. Prior competency in interventional endoscopy, procedural training models, POEM observation and education, proctorship, and interdisciplinary patient care are recommended.

Inflammation is associated with incident hypertension in patients with axial spondyloarthritis: A longitudinal cohort study.

OBJECTIVES: To elucidate the risk factors for the development of incident hypertension (IHT) in patients with axial spondyloarthritis (axSpA). METHODS: We conducted a retrospective cohort study in axSpA patients who were recruited from 2001 to 2019 from a university clinic in Hong Kong. Patients with HT and/or anti-hypertensive drug use at baseline were excluded. They were followed until the end of 2020. The outcome was IHT, defined by a diagnosis and a prescription for an antihypertensive drug. Baseline and time-varying Cox regression analyses adjusting for age, sex, and body mass index (BMI), were used to assess the relationship between drug use, inflammatory burden, and IHT. RESULTS: Four hundred and thirteen patients [age: 34(25-43) years, male: 319 (77.2%)] were recruited. After a median follow-up of 12 (6-17) years, 58 patients (14%) developed IHT (IHT+group). Among all the baseline variables, disease duration and delay in diagnosis were the independent predictors for IHT based on the Cox regression model. In the multivariate Cox regression analysis, baseline disease duration, delay in diagnosis and time-varying ESR levels were independent predictors associated with an increased risk of IHT. IHT risk was significantly increased in patients with disease duration >5 years. The use of anti-inflammatory drugs was not associated with the development of IHT. CONCLUSION: Higher inflammatory burden as reflected by a longer disease duration, delay diagnosis and higher ESR levels, were predictors associated with IHT after adjusting for traditional CV risk factors. These data support routine screening for hypertension in axSpA patients, especially those with longer disease duration.

What is already known about this subject?• Patients with axial spondyloarthritis (axSpA) have a higher risk of cardiovascular (CV) disease compared with the general population. Hypertension (HT) is one of the most important modifiable risk factors. Whether increased inflammatory pathways or the use of anti-inflammatory therapies contribute toward the increased prevalence of HT in axSpA remained controversial.What does this study add?• First, higher inflammatory burden as reflected by a longer baseline disease duration, delay in diagnosis and higher ESR levels were predictors of incident HT (IHT) after adjusting for traditional CV risk factors in axSpA. Second, IHTrisk was significantly increased in pati\ents with disease duration >5 years.How might this impact on clinical practice or future developments?• Early diagnosis and adequate control of systematic inflammation may be important to prevent the development of HT. Routine screening for hypertension in axSpA patients should be considered, especially in patients with longer disease duration.

The causal effect of interleukin-17 on the risk of psoriatic arthritis: a Mendelian randomization study.

OBJECTIVE: To determine causal associations between genetically predicted TNF-α, IL-12p70 and IL-17 levels and risk of PsA. METHODS: The publicly available summary-level findings from genome-wide association studies (GWAS) was used to identify loci influencing normal physiological concentrations of TNF-α, IL-12p70 and IL-17 (n = 8293) among healthy individuals as exposure and a GWAS for PsA from the UK Biobank (PsA = 900, control = 462 033) as the outcome. A two-sample Mendelian randomization (MR) analysis was performed using the inverse-variance weighted (IVW), weighted median and MR-Egger regression methods. Sensitivity analysis and MR-Egger regression analysis were performed to evaluate the heterogeneity and pleiotropic effects of each variant. RESULTS: Single-nucleotide polymorphisms (SNPs) at genome-wide significance from GWASs on TNF-α, IL-12p70 and IL-17 were identified as the instrumental variables. The IVW method indicated a causal association between increased IL-17 level and risk of PsA (ß = -0.00186 per allele, s.e. = 0.00043, P = 0.002). Results were consistent in the weighted median method (ß = -0.00145 per allele, s.e. = 0.00059, P = 0.014) although the MR-Egger method suggested a non-significant association (ß = -0.00133 per allele, s.e. = 0.00087; P = 0.087). Single SNP MR results revealed that the C allele of rs117556572 was robustly associated with risk of PsA (ß = 0.00210, s.e. = 0.00069, P = 0.002). However, no evidence for a causal effect was observed between TNF-α, IL-12p70, decreased IL-17 levels and risk of PsA. CONCLUSION: Our findings provide preliminary evidence that genetic variants predisposing to higher physiological IL-17 level are associated with decreased risk of PsA.

Activation of Muscle-Specific Kinase (MuSK) Reduces Neuromuscular Defects in the Delta7 Mouse Model of Spinal Muscular Atrophy (SMA).

Spinal muscular atrophy (SMA) is a motor neuron disease caused by insufficient levels of the survival motor neuron (SMN) protein. One of the most prominent pathological characteristics of SMA involves defects of the neuromuscular junction (NMJ), such as denervation and reduced clustering of acetylcholine receptors (AChRs). Recent studies suggest that upregulation of agrin, a crucial NMJ organizer promoting AChR clustering, can improve NMJ innervation and reduce muscle atrophy in the delta7 mouse model of SMA. To test whether the muscle-specific kinase (MuSK), part of the agrin receptor complex, also plays a beneficial role in SMA, we treated the delta7 SMA mice with an agonist antibody to MuSK. MuSK agonist antibody #13, which binds to the NMJ, significantly improved innervation and synaptic efficacy in denervation-vulnerable muscles. MuSK agonist antibody #13 also significantly increased the muscle cross-sectional area and myofiber numbers in these denervation-vulnerable muscles but not in denervation-resistant muscles. Although MuSK agonist antibody #13 did not affect the body weight, our study suggests that preservation of NMJ innervation by the activation of MuSK may serve as a complementary therapy to SMN-enhancing drugs to maximize the therapeutic effectiveness for all types of SMA patients.

DAPSA, carotid plaque and cardiovascular events in psoriatic arthritis: a longitudinal study.

OBJECTIVE: To examine whether Disease Activity in Psoriatic Arthritis (DAPSA) reflecting the inflammatory component of psoriatic arthritis (PsA) can predict cardiovascular (CV) events independent of traditional CV risk factors and subclinical carotid atherosclerosis. METHODS: A cohort analysis was performed in patients with PsA who had been followed since 2006. The outcome of interest was first CV event. Four different CV disease (CVD) risk scores and DAPSA were computed at baseline. The presence of carotid plaque (CP) and carotid intima-media thickness (CIMT) was also determined in a subgroup of patients using high-resolution ultrasound. The association between DAPSA, CVD risk scores, CP, CIMT and the occurrence of CV events was assessed using Cox proportional hazard models. RESULTS: 189 patients with PsA (mean age: 48.9 years; male: 104 (55.0%)) were recruited. After a median follow-up of 9.9 years, 27 (14.3%) patients developed a CV event. Higher DAPSA was significantly associated with an increased risk of developing CV events (HR: 1.04, 95% CI (1.01 to 1.08), p=0.009). The association remained significant after adjusting for all CV risk scores in the multivariable models. In the subgroup analysis, 154 patients underwent carotid ultrasound assessment and 23 (14.9%) of them experienced a CV event. CP was associated with increased risk of developing CV events after adjusting for three CV risk scores and DAPSA, with HR ranging from 2.35 to 3.42. CONCLUSION: Higher DAPSA and the presence of CP could independently predict CVD events in addition to traditional CV risk scores in patients with PsA.

TMS motor mapping in brain tumor patients: more robust maps with an increased resting motor threshold.

OBJECTIVE: Navigated transcranial magnetic stimulation (nTMS) has found widespread usage across many clinical centers as part of their surgical planning routines. NTMS offers a non-invasive approach to delineation of the motor cortex, in which the region is outlined through electromagnetic stimulation and electromyographic recordings of target muscles. Several neurophysiological parameters such as the motor evoked potential (MEP) and its derivatives, the resting motor threshold (RMT) and motor latency, are collected. The present study investigates the clinical feasibility and reproducibility of increasing the MEP threshold in brain tumor patients, with the goal to improve the robustness of the procedure. MATERIALS AND METHODS: Twenty-three subjects with peri-motor cortex tumors underwent motor mapping with nTMS. RMT was calculated with both conventional 50-µV and experimental 500-µV MEP amplitude thresholds. Motor mapping was performed with 105% of both RMTs stimulator intensity using the FDI as the target muscle. RESULTS: Motor mapping was possible in 20 patients with both the conventional and experimental thresholds. No significant differences in area size were found between motor area maps generated with a conventional 50-µV threshold in comparison to those generated with the higher 500-µV threshold (50 µV 272.56 mm2 [170.47-434.31] vs. 500 µV 240.54 mm2 [169.77-362.84], P = 0.34). Latency time was significantly reduced in 500-µV recordings relative to 50-µV recordings (50 µV 23.38 ms [22.55-24.51] vs. 500 µV 22.57 ms [21.41-23.70], P < 0.001). Both electric field intensity (50 µV 63.81 V/m [54.26-76.11] vs. 500 µV 77.83 V/m [65.21-93.94], P < 0.001) and RMT (50 µV 33 MSO% [28-36] vs. 500 µV 39.5 MSO% [32-44], P < 0.001) were significantly greater with the higher 500-µV threshold. CONCLUSIONS: Our study demonstrates the feasibility of increasing the MEP detection threshold to 500 µV in brain tumor patients for RMT determination and motor area mapping with nTMS.

Preservation of motor maps with increased motor evoked potential amplitude threshold in RMT determination.

OBJECTIVE: Non-invasive pre-surgical mapping of eloquent brain areas with navigated transcranial magnetic stimulation (nTMS) is a useful technique linked to the improvement of surgical planning and patient outcomes. The stimulator output intensity and subsequent resting motor threshold determination (rMT) are based on the motor-evoked potential (MEP) elicited in the target muscle with an amplitude above a predetermined threshold of 50 µV. However, a subset of patients is unable to achieve complete relaxation in the target muscles, resulting in false positives that jeopardize mapping validity with conventional MEP determination protocols. Our aim is to explore the feasibility and reproducibility of a novel mapping approach that investigates how an increase of the MEP amplitude threshold to 300 and 500 µV affects subsequent motor maps. MATERIALS AND METHODS: Seven healthy subjects underwent motor mapping with nTMS. RMT was calculated with the conventional methodology in conjunction with experimental 300- and 500-µV MEP amplitude thresholds. Motor mapping was performed with 105% of rMT stimulator intensity using the FDI as the target muscle. RESULTS: Motor mapping was possible in all patients with both the conventional and experimental setups. Motor area maps with a conventional 50-µV threshold showed poor correlation with 300-µV (α = 0.446, p < 0.001) maps, but showed excellent consistency with 500-µV motor area maps (α = 0.974, p < 0.001). MEP latencies were significantly less variable (23 ms for 50 µV vs. 23.7 ms for 300 µV vs. 23.7 ms for 500 µV, p < 0.001). A slight but significant increase of the electric field (EF) value was found (EF: 60.8 V/m vs. 64.8 V/m vs. 66 V/m p < 0.001). CONCLUSION: Our study demonstrates the feasibility of increasing the MEP detection threshold to 500 µV in rMT determination and motor area mapping with nTMS without losing precision.

Evaluation of an Ecohealth Approach to Public Health Intervention in Ha Nam, Vietnam.

CONTEXT: Ecohealth is a transdisciplinary research approach that considers socio-economic, cultural, and environmental factors. Ecohealth program assessment is sometimes unable to capture the process of change, especially when the evidence is not well documented. As such, there is a need to better understand how ecohealth approaches are understood, integrated, and adapted in practice to support the sustainability of the approach. OBJECTIVE: To evaluate the use of an ecohealth approach to a community-based intervention to improve environmental sanitation and draw lessons learned for similar public health initiatives. DESIGN: An iterative evaluation approach involving 27 in-depth interviews and 9 focus group discussions was used to gather feedback on the intervention activities and outcomes from all participants. SETTING AND PARTICIPANTS: The study site was Hoang Tay commune, Kim Bang district, Ha Nam province. The participants included 12 farmers, 4 local policy makers, and 7 researchers from Hanoi University of Public Health. RESULTS: The farmers provided specific shortcomings of the biogas procedure steps, while the local authorities identified new and more effective ways to promote sanitation guidelines. Outcomes, as behavior changes, in 3 participant groups were captured. CONCLUSION: Participation in ecohealth interventions should be collegial to give opportunities for all related stakeholders to build capacity, support, and achieve the transdisciplinary principle. This also helps ensure that the community-based solutions are incorporated in public health interventions. Participatory monitoring and evaluation should support the understanding of the implementation process to capture intervention outcomes.

How does the media portray drinking water security in Indigenous communities in Canada? An analysis of Canadian newspaper coverage from 2000-2015.

BACKGROUND: Drinking water insecurity and related health outcomes often disproportionately impact Indigenous communities internationally. Understanding media coverage of these water-related issues can provide insight into the ways in which public perceptions are shaped, with potential implications for decision-making and action. This study aimed to examine the extent, range, and nature of newspaper coverage of drinking water security in Canadian Indigenous communities. METHODS: Using ProQuest database, we systematically searched for and screened newspaper articles published from 2000 to 2015 from Canadian newspapers: Windspeaker, Toronto Star, The Globe and Mail, and National Post. We conducted descriptive quantitative analysis and thematic qualitative analysis on relevant articles to characterize framing and trends in coverage. RESULTS: A total of 1382 articles were returned in the search, of which 256 articles were identified as relevant. There was limited coverage of water challenges for Canadian Indigenous communities, especially for Métis (5%) and Inuit (3%) communities. Most stories focused on government responses to water-related issues, and less often covered preventative measures such as source water protection. Overall, Indigenous peoples were quoted the most often. Double-standards of water quality between Indigenous and non-Indigenous communities, along with conflict and cooperation efforts between stakeholders were emphasized in many articles. CONCLUSION: Limited media coverage could undermine public and stakeholder interest in addressing water-related issues faced by many Canadian Indigenous communities.

Identification of inherently antioxidant regions in proteins with radical-directed dissociation mass spectrometry.

Antioxidant peptides such as glutathione play critically important roles within cells by opposing the action of oxidative species. Similarly all proteins may, as a secondary function, potentially contribute to the antioxidant capacity of the cellular milieu, though this possibility has not been thoroughly explored previously. Herein it is demonstrated that, in addition to radical quenching solution-phase behavior, antioxidant peptides display an astonishing ability to sequester radicals in the gas phase. Compared to other peptides of similar sequence and size, radical antioxidant peptides exhibit very little radical-directed dissociation when subjected to collisional activation in the gas phase. Importantly, this property can be leveraged in highly sensitive and rapid mass spectrometry based experiments to identify antioxidant peptides. Examination of peptides derived from human serum albumin (HSA), which is a protein known to behave as an antioxidant, revealed three previously unknown peptide regions that exhibit antioxidant capacity. One of these peptides, VAHRFK, shows antioxidant capacity comparable to that of glutathione. It is likely that these peptide regions contribute to the overall antioxidant capacity of HSA. In comparison with previous methods, the present technique is significantly more sensitive and less time-consuming, which should enable more wide-scale examination of antioxidant peptides that are relevant to redox homeostasis, food chemistry, and disease.

Incidence and risk factors of major cardiovascular events in rheumatoid arthritis and psoriatic arthritis: A population-based cohort study.

OBJECTIVE: To evaluate the incidence and risk factors of major adverse cardiovascular events (MACE) in rheumatoid arthritis (RA) and psoriatic arthritis (PsA) patients. METHODS: A population-based retrospective cohort of RA and PsA patients was identified in a citywide database. All patients recruited from Jan 2006 to Dec 2015 were followed until the end of 2018. The outcome was the occurrence of a first MACE. Covariates of interest included traditional cardiovascular (CV) risk factors, inflammatory markers and pharmacotherapies. The independent predictors of MACE were identified by the time-dependent cox proportional hazard models. RESULTS: A total of 13,905 patients (12,233 RA and 1,672 PsA) were recruited. After a total of 119,571 patient-years of follow-up, 934 (6.7%) patients developed a first MACE. RA and PsA patients had similar adjusted incidence (incidence rate ratio 0.96, 95 % CI 0.75-1.22, p = 0.767). After adjusting for traditional CV risk factors, the time-varying erythrocyte sedimentation (ESR) rate and C-reactive protein (CRP) levels, and the use of glucocorticoids were independently associated with higher risk of MACE in both the RA and PsA cohorts. In RA, the use of methotrexate and non-steroidal anti-inflammatory drugs (NSAIDs) were associated with fewer MACE. The use of biologic disease modifying anti-rheumatic drugs was not associated with MACE in both RA and PsA. CONCLUSION: The incidence of MACE was similar in RA and PsA. Systemic inflammation and glucocorticoid use independently increased the risk of MACE in inflammatory arthritis, while methotrexate and NSAIDs use were protective against the development of MACE in RA.

Impact of inflammation and anti-inflammatory therapies on the incidence of major cardiovascular events in patients with ankylosing spondylitis: A population-based study.

OBJECTIVE: To examine the independent effect of inflammatory burden and various treatments on the risk of incident major adverse cardiovascular events (MACE) in ankylosing spondylitis (AS) patients. METHODS: AS patients were retrospectively selected from a territory-wide database between 2006 and 2015, and were followed until the end of 2018. The primary outcome was the first occurrence of MACE. Multivariate time-varying Cox proportional hazard models were used to determine the associations between inflammatory burden (measured by c-reactive protein [CRP] and erythrocyte sedimentation rate [ESR]) and different therapies with incident MACE, after adjusting for traditional cardiovascular (CV) risk factors. RESULTS: A total of 3827 patients with AS (mean age: 45.2 ± 15.0 years, male: 2911 [76.1 %]) were recruited. After a follow-up of 23,275 person-years, 135 patients (3.5 %) developed a first MACE. Univariate analyses showed that elevated ESR and CRP levels, and the use of glucocorticoids were associated with a significantly higher risk of MACE, while the use of sulfasalazine (SLZ), biologic DMARDs and non-cyclooxygenase-2 inhibitors (non-COX-IIi) were associated with reduced risk of MACE. After adjusting for CV risk factors in the multivariable models, only ESR (HR: 1.02; ESR ≥30 mm/h, HR:1.94) and CRP level (HR: 1.14; CRP >3 mg/dl HR:5.43) remained significantly associated with increased risk of MACE, while SLZ use (HR: 0.41-0.52) was protective against MACE. CONCLUSION: High inflammatory burden was an independent predictor associated with an increased risk of MACE, while the use of SLZ might reduce risk of incident MACE in patients with AS.

Combination therapy of beta-blockers and digoxin is associated with increased risk of major adverse cardiovascular events and all-cause mortality in patients with atrial fibrillation: a report from the GLORIA-AF registry.

The effect of digoxin and beta-blockers on cardiovascular outcomes and mortality remains unclear. The study aimed to determine differences in cardiovascular (CV) outcomes and death rates among patients with atrial fibrillation (AF) who were prescribed with beta-blockers, digoxin or combination therapy. Data from phase II/III of the prospective Global Registry on Long-Term Oral Anti-thrombotic Treatment in Patients with Atrial Fibrillation (GLORIA-AF) were analysed. The risk of major cardiovascular events (MACE) and death among patients with different prescriptions using COX proportional hazard regression was considered. Propensity score (PS) matching and weighting were further used to adjust for potential confounders of prescription use. A total of 14,201 patients [median age: 71.0 (IQR 64.0-77.0) years; 46.2% female] were recruited. After a median follow-up of 3.0 (IQR 2.4-3.1) years, 864 MACE, and 988 all-cause deaths were recorded. The incidence rate (IR) of MACE was 22.4 (95%CI 21.0-24.0) per 1000 person-years, while the IR of all-cause death was 25.4 (95%CI 23.8-27.0) per 1000 person-years. After multivariate adjustment with Cox regression, the risk of MACE (HR 1.35, 95% CI 1.09-1.68) and the risk of all-cause death (HR 1.28, 95%CI 1.04-1.57) were significantly higher in the combination therapy group, compared to the beta-blockers alone group. The risks of MACE and all-cause death remained significant in both PS matched and PS weighted cohort Among AF patients, combination therapy of beta-blockers and digoxin was associated with higher risks of MACE and all-cause death compared to beta-blockers alone.

Navigating One Health in research-for-development: Reflections on the design and implementation of the CGIAR Initiative on One Health.

Adopting One Health approaches is key for addressing interconnected health challenges. Yet, how to best put One Health into practice in research-for-development initiatives aiming to 'deliver impacts' remains unclear. Drawing on the CGIAR Initiative on One Health - a global initiative to address zoonotic diseases, antimicrobial resistance, and food and water safety - we reflect on challenges during program conception and implementation, prompting us to suggest improvements in multisectoral collaboration, coordination, and communication. Our approach involves conducting a researcher-centered process evaluation, comprising individual interviews that are subsequently thematically analyzed and synthesized. The key takeaway is that limited time for planning processes and short program timelines compared to envisioned development impacts may impede research-for-development efforts. Yet, collaborative work can be successful when adequate time and resources are allocated for planning with minimal disruption throughout implementation. Additionally, due to the multifaceted nature of One Health initiatives, it is important to pay attention to co-benefits and trade-offs, where taking action in one aspect may yield advantages and disadvantages in another, aiding to identify sustainable One Health development pathways. Forming close partnerships with national governments and local stakeholders is essential not only to promote sustainability but also to ensure local relevance, enhancing the potential for meaningful impact. Finally, regularly assessing progress toward development goals is critical as development stands as an overarching objective.

Prevalence of Oral Pathogen Slackia exigua among Clinical Orthodontic and Non-Orthodontic Saliva Samples.

Slackia exigua (SE) is a recently identified intestinal microbe, which recent oral surveys suggest may be associated with oral diseases including caries and periodontal disease. Based upon the lack of information regarding this organism, the primary objective of this study was to determine the oral prevalence of this microbe and any potential associations with patient characteristics such as age, sex, or the presence of orthodontic appliances. This retrospective study involved the screening of an existing saliva repository composed of previously collected unstimulated clinical saliva samples. More specifically, N = 266 were identified and screened using a spectrophotometer at absorbances of A260 and A280 nm to determine their DNA purity and concentration. qPCR screening of these samples revealed a higher prevalence of Slackia exigua positive samples among pediatric patients (63.1%) compared with adults (36.9%) in this clinic population, p = 0.0007. In addition, higher percentages of Slackia exigua were observed among orthodontic patients (71.2%) compared with non-orthodontic patients (28.8%), p = 0.0001. These results did not vary by sex with nearly equal percentages of Slackia exigua positive males and females among adult and pediatric patients, as well as orthodontic and non-orthodontic samples. These results suggest a strong potential for association between the prevalence of this organism with age as well as orthodontic status, given that younger patients and those with orthodontic brackets (regardless of age) were most likely to harbor this pathogen in sufficient levels to be detected in saliva. More research will be needed to determine any associations with specific outcomes, such as caries or periodontal disease, among Slackia exigua positive patients within these specific populations.

How can climate change and its interaction with other compounding risks be considered in evaluation? Experiences from Vietnam.

While evaluations play a critical role in accounting for and learning from context, it is unclear how evaluations can take account of climate change. Our objective was to explore how climate change and its interaction with other contextual factors influenced One Health food safety programs. To do so, we integrated questions about climate change into a qualitative evaluation study of an ongoing, multi-sectoral program aiming to improve pork safety in Vietnam called SafePORK. We conducted remote interviews with program researchers (n = 7) and program participants (n = 23). Based on our analysis, researchers believed climate change had potential impacts on the program but noted evidence was lacking, while program participants (slaughterhouse workers and retailers) shared how they were experiencing and adapting to the impacts of climate change. Climate change also interacted with other contextual factors to introduce additional complexities. Our study underscored the importance of assessing climate factors in evaluation and building adaptive capacity in programming.

High inflammatory burden predicts cardiovascular events in patients with axial spondyloarthritis: a long-term follow-up study.

Background: Axial spondyloarthritis (axSpA) patients are at higher risk of cardiovascular (CV) disease (CVD) than the general population, partly due to consequences of inflammation or its treatment. But relationship between inflammation in axSpA and cardiovascular events (CVE) is unknown. Objectives: To examine whether inflammatory burden over time can predict CVE independent of baseline CV risk factors in axSpA patients. Design: A cohort analysis was performed in patients who had been recruited since January 2001. The primary outcome was a first CVE occurring between January 2001 and December 2020. Methods: Three CVD risk scores were computed at baseline. The performance of the original and modified (*1.5 multiplication factor) CV risk algorithms were assessed. Time-varying Cox proportional hazard models and Kaplan-Meier survival analysis were used to assess whether inflammatory burden (Bath ankylosing spondylitis disease activity index [BASDAI] and inflammatory markers), nonsteroidal anti-inflammatory drugs (NSAIDs) and disease modifying antirheumatic drugs (DMARDs) can predict the development of first CVE. Results: 463 patients (35 [26-45] years, male: 360 [77.8%]) were recruited. After a median follow-up of 12 (7-19) years, 61 patients (13.2%) experienced a first CVE. Traditional/modified CV risk scores underestimated CV risk. Erythrocyte sedimentation rate (ESR) ⩾ 20 mm/h was associated with a significantly higher risk of CVE during follow-up (HR: 2.07, 95%CI [1.10, 3.98], p = 0.008). Active disease as indicated by a rising BASDAI also showed positive trend towards a higher risk of developing CVE over time. After adjusting for CV risk scores in the multivariable models, high ESR level (ESR ⩾ 20 mm/h) over time remained significantly associated with a higher risk of developing CV events. Conclusion: Increased inflammatory burden as reflected by elevated ESR levels (ESR ⩾ 20) was associated with increased risk of CVE, while the use of NSAIDs and DMARDs were not.
