Background: Chronic back pain is a common musculoskeletal disorder, disproportionately affecting rural and Indigenous people. Saskatchewan has a relatively high proportion of rural and Indigenous residents; therefore, understanding barriers and facilitators to accessing healthcare are needed to improve healthcare service delivery. Methods: A provincial-wide telephone survey explored experiences and perceived healthcare access barriers and facilitators among 384 Saskatchewan residents who experienced chronic low back pain. Chi-squared tests were performed to determine if people who lived in urban versus rural areas differed in the proportion who had accessed services from various healthcare practitioners. T-test and Mann-Whitney U analyses were conducted to determine differences between urban and rural, and Indigenous and non-Indigenous respondents. Results: Of 384 residents surveyed, 234 (60.9%) reported living in a rural location; 21 (5.5%) identified as Indigenous. Wait times (47%), cost (40%), travel (39%), and not knowing how to seek help (37%) were the most common barriers for Saskatchewan residents seeking care, with travel being the only barrier that was significantly different between rural and urban respondents ( P ⩽ .001). Not knowing where to go to access care or what would help their low back pain ( P = .03), lack of cultural sensitivity ( P = .007), and comfort discussing problems with health care professionals ( P = .26) were greater barriers for Indigenous than non-Indigenous participants. Top facilitators (>50% of respondents) included publicly funded healthcare, locally accessible healthcare services, and having supportive healthcare providers who facilitate referral to appropriate care, with urban respondents considering the latter 2 as greater facilitators than rural respondents. Telehealth or virtual care ( P = .013) and having healthcare options nearby in their community ( P = .045) were greater facilitators among Indigenous participants compared to non-Indigenous respondents. Conclusions: Rural, urban, Indigenous, and non-Indigenous people report overlapping and unique barriers and facilitators to accessing care for chronic low back pain. Understanding perceived access experiences will assist in developing more effective care models for specific communities or regions.

Background: Acute kidney injury (AKI) resulting in kidney replacement therapy is rising among critically ill adults. Long-term kidney replacement therapy and critical illness are independently linked to acute and prolonged cognitive impairment, and structural brain pathology. Poor regional cerebral oxygenation (rSO2) may be a contributing factor. Objective: To assess the feasibility of testing the association between intradialytic rSO2 and acute and long-term neurological outcomes. Design: Longitudinal observational study. Setting and Participants: We enrolled patients initiating continuous kidney replacement therapy or intermittent hemodialysis in the Kingston Health Sciences Centre (KHSC) Intensive Care Unit (ICU). Measurements and Methods: rSO2 was monitored during the first 72 hours of continuous kidney replacement therapy or throughout each intermittent hemodialysis session. We measured acute neurological impairment by daily delirium screening and long-term neurocognitive outcomes using the Kinarm robot, Repeatable Battery for the Assessment of Neuropsychological Status, and brain magnetic resonance imaging. Results: Of 484 ICU patients, 26 met the screening criteria. Two declined, and 13 met at least one exclusion criteria. Eleven patients were enrolled. Eight died in ICU, one died 2 months after discharge, and one declined follow-up. Data capture rates were high: rSO2/vitals (91.3%), and delirium screening and demographics (100%). Longitudinal testing was completed in 50% (1 of 2) of survivors. Limitations: Enrollment was low due to a variety of factors, limiting our ability to evaluate long-term outcomes. Conclusion: rSO2 and delirium data collection is feasible in critically ill patients undergoing kidney replacement therapy; high mortality limits follow-up.

Published: August 2023

Background: Arthroscopic repair of longitudinal tears in the medial meniscal posterior horn (MMPH) has been reported to result in high rates of meniscal healing when performed alongside anterior cruciate ligament reconstruction (ACLR). However, studies that have focused on longitudinal tears and their impact on clinical outcomes after arthroscopic repair are insufficient. Purpose: To investigate the clinical outcome and healing status after concomitant arthroscopic ACLR and repair of MMPH peripheral longitudinal tears, with respect to the tear length. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 263 patients who underwent concurrent arthroscopic suture repair of longitudinal tears of the MMPH and ACLR were enrolled. All patients had 2-year postoperative magnetic resonance imaging (MRI) evaluations, and 61% of patients underwent a second-look arthroscopy. The exclusion criteria were partial meniscectomies and multiligament injuries. Patients were assessed pre- and postoperatively for clinical scores, amount of anterior translation, grade of pivot shift, and presence of meniscal tear extension. According to the length of longitudinal tears, patients were classified into 2 groups: (1) patients with tears that were located in the posterior compartment and (2) patients with tears that extended to the midbody of the meniscus. Binary stepwise logistic regression analysis was used to evaluate the risk factors for unhealed menisci as identified by MRI. Results: A total of 83 patients were included in this study—52 patients (group 1) had MMPH tears without tear extension and 31 patients (group 2) had MMPH tears with tear extension. There were no differences in outcomes between the groups, including the healing rate after meniscal repair ( P > .05). Based on postoperative MRI scans, 67 patients (80.7%) were categorized as completely healed and 16 patients (19.3%) as unhealed. There were no significant differences between the completely healed and unhealed groups in outcomes or the rate of preoperative midbody tear extension. Higher body mass index and lower preoperative Lysholm scores were identified as risk factors for unhealed menisci. Conclusion: Overall, the rate of complete healing of MMPH tears repaired concomitantly with ACLR was 80.7% (67/83), and midbody tear extension did not affect the healing rate of the repaired meniscus. Results indicate that suture repair for unstable MMPH tears should be considered regardless of tear size.

Published: August 2023

Introduction Monteggia-like lesions are rare injuries in adults that include a wide spectrum of complex fracture-dislocations of the proximal ulna and radius. In this retrospective study, we performed a modified Boyd approach and a standard surgical protocol for the treatment of these lesions. Our aim was to evaluate the results of the operative treatment for patients with Monteggia-like lesions, using a modified Boyd approach. Materials and Methods We present a retrospective study of 14 patients who underwent surgical treatment for Monteggia-like lesions. Preoperative clinical and radiological evaluation was performed. In 5 cases radial head prosthesis was placed, and in 3 cases the radial fracture was stabilized with the use of interfragmental screws. Regarding the proximal ulnar fracture, ORIF-anatomical plate and ORIF-straight plate was used in 12 and 2 cases, respectively. Results Average clinical follow up was 16.9 months. Postoperatively, the mean Mayo Elbow Performance score was 83.4 points (range 70-100) and the mean visual analog scale was 1.7 (range 0-14). Mean flexion and loss of extension were 122.1° (range 80°-140°) and 21.4° (range 5°-40°), respectively. Mean supination of the forearm was 66.8° (range 50°-80°) and the mean pronation was 67.5° (range 60°-75°). Heterotopic ossification was observed in 3 patients (21.4%) and 1 patient developed stiffness (7.1%). The patient who developed stiffness underwent reoperation for plate removal and arthrolysis, with satisfactory results. Conclusions The surgical treatment of Monteggia-like lesions in adults remains a challenge. In the present study, the use of a standard surgical protocol, with a modified Boyd approach, successfully restores the movement and stability of the elbow, with a low complication rate.

Published: August 2023

Abstract
Constitutive mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1) activity drives survival of malignant lymphomas addicted to chronic B-cell receptor signaling, oncogenic CARD11, or the API2-MALT1 (also BIRC3::MALT1) fusion oncoprotein. Although MALT1 scaffolding induces NF-κB–dependent survival signaling, MALT1 protease function is thought to augment NF-κB activation by cleaving signaling mediators and transcriptional regulators in B-cell lymphomas. However, the pathological role of MALT1 protease function in lymphomagenesis is not well understood. Here, we show that TRAF6 controls MALT1-dependent activation of NF-κB transcriptional responses but is dispensable for MALT1 protease activation driven by oncogenic CARD11. To uncouple enzymatic and nonenzymatic functions of MALT1, we analyzed TRAF6-dependent and -independent as well as MALT1 protease–dependent gene expression profiles downstream of oncogenic CARD11 and API2-MALT1. The data suggest that by cleaving and inactivating the RNA binding proteins Regnase-1 and Roquin-1/2, MALT1 protease induces posttranscriptional upregulation of many genes including NFKBIZ/IκBζ, NFKBID/IκBNS, and ZC3H12A/Regnase-1 in activated B-cell–like diffuse large B-cell lymphoma (ABC DLBCL). We demonstrate that oncogene-driven MALT1 activity in ABC DLBCL cells regulates NFKBIZ and NFKBID induction on an mRNA level via releasing a brake imposed by Regnase-1 and Roquin-1/2. Furthermore, MALT1 protease drives posttranscriptional gene induction in the context of the API2-MALT1 fusion created by the recurrent t(11;18)(q21;q21) translocation in MALT lymphoma. Thus, MALT1 paracaspase acts as a bifurcation point for enhancing transcriptional and posttranscriptional gene expression in malignant lymphomas. Moreover, the identification of MALT1 protease–selective target genes provides specific biomarkers for the clinical evaluation of MALT1 inhibitors.

Published: August 2023

Abstract
Background
Telomerase reverse transcriptase (TERT) plays a crucial role in synthesizing telomeric repeats that safeguard chromosomes from damage and fusion, thereby maintaining genome stability. Mutations in the TERT gene can lead to a deviation in gene expression, impaired enzyme activity, and, as a result, abnormal telomere shortening. Genetic markers of productivity traits in livestock can be developed based on the TERT gene polymorphism for use in marker-associated selection (MAS). In this study, a bioinformatic-based approach is proposed to evaluate the effect of missense single-nucleotide polymorphisms (SNPs) in the pig TERT gene on enzyme function and structure, with the prospect of developing genetic markers.

Results
A comparative analysis of the coding and amino acid sequences of the pig TERT was performed with corresponding sequences of other species. The distribution of polymorphisms in the pig TERT gene, with respect to the enzyme’s structural-functional domains, was established. A three-dimensional model of the pig TERT structure was obtained through homological modeling. The potential impact of each of the 23 missense SNPs in the pig TERT gene on telomerase function and stability was assessed using predictive bioinformatic tools utilizing data on the amino acid sequence and structure of pig TERT.

Conclusions
According to bioinformatic analysis of 23 missense SNPs of the pig TERT gene, a predictive effect of rs789641834 (TEN domain), rs706045634 (TEN domain), rs325294961 (TRBD domain) and rs705602819 (RTD domain) on the structural and functional parameters of the enzyme was established. These SNPs hold the potential to serve as genetic markers of productivity traits. Therefore, the possibility of their application in MAS should be further evaluated in associative analysis studies.

Published: August 2023

Abstract
Background
Staphylococcus aureus can infect and adapt to multiple host species. However, our understanding of the genetic and evolutionary drivers of its generalist lifestyle remains inadequate. This is particularly important when considering local populations of S. aureus, where close physical proximity between bacterial lineages and between host species may facilitate frequent and repeated interactions between them. Here, we aim to elucidate the genomic differences between human- and animal-derived S. aureus from 437 isolates sampled from disease cases in the northeast region of the United States.

Results
Multi-locus sequence typing revealed the existence of 75 previously recognized sequence types (ST). Our population genomic analyses revealed heterogeneity in the accessory genome content of three dominant S. aureus lineages (ST5, ST8, ST30). Genes related to antimicrobial resistance, virulence, and plasmid types were differentially distributed among isolates according to host (human versus non-human) and among the three major STs. Across the entire population, we identified a total of 1,912 recombination events that occurred in 765 genes. The frequency and impact of homologous recombination were comparable between human- and animal-derived isolates. Low-frequency STs were major donors of recombined DNA, regardless of the identity of their host. The most frequently recombined genes (clfB, aroA, sraP) function in host infection and virulence, which were also frequently shared between the rare lineages.

Conclusions
Taken together, these results show that frequent but variable patterns of recombination among co-circulating S. aureus lineages, including the low-frequency lineages, that traverse host barriers shape the structure of local gene pool and the reservoir of host-associated genetic variants. Our study provides important insights to the genetic and evolutionary factors that contribute to the ability of S. aureus to colonize and cause disease in multiple host species. Our study highlights the importance of continuous surveillance of S. aureus circulating in different ecological host niches and the need to systematically sample from them. These findings will inform development of effective measures to control S. aureus colonization, infection, and transmission across the One Health continuum.
Mechanisms of systemic resistance to pathogen infection in plants and their potential application in forestry
Authors: Wilson S. K. , Pretorius T. , Naidoo S. 
Published: August 2023

Abstract
Background
The complex systemic responses of tree species to fight pathogen infection necessitate attention due to the potential for yield protection in forestry.

Results
In this paper, both the localized and systemic responses of model plants, such as Arabidopsis and tobacco, are reviewed. These responses were compared to information available that investigates similar responses in woody plant species and their key differences were highlighted. In addition, tree-specific responses that have been documented were summarised, with the critical responses still relying on certain systemic acquired resistance pathways. Importantly, coniferous species have been shown to utilise phenolic compounds in their immune responses. Here we also highlight the lack of focus on systemic induced susceptibility in trees, which can be important to forest health.

Conclusions
This review highlights the possible mechanisms of systemic response to infection in woody plant species, their potential applications, and where research may be best focused in future.

Abstract
Objectives
Unmet health-related social needs can influence health outcomes and increase healthcare utilization. There is growing interest in integrating social needs care into healthcare delivery. We conducted an assessment of health-related social needs in an academic adult primary care practice in San Francisco, California.

Methods
We recruited a random convenience sample of adult English-, Chinese- or Spanish-speaking patients from clinic waiting rooms at the study sites to complete a self-administered, anonymous survey. We used the Accountable Health Communities Health-Related Social Needs Screening Tool for these domains: housing instability, food insecurity, transportation problems, utility help needs, interpersonal safety, financial strain, and family/community support. We conducted univariate and multivariate analyses adjusting for age, sex and survey language.

Results
679 patients completed the survey. Respondents were 57% female and mean age of 58 ± 18 years old. 54% of patients had at least one unmet health-related social need. The most prevalent health-related social needs were financial strain (35%), at least one issue with housing conditions (27%), and food insecurity (23%). Respondents completing the survey in Spanish had significantly higher odds of reporting food insecurity (AOR 3.97, 95%CI 1.86, 8.46), transportation problems (AOR 3.13, 95%CI 1.32, 7.43), and need for support with activities of daily living (AOR 4.58, 95%CI 2.04, 10.25) than respondents completing the survey in English.

Conclusions
The burden of unmet health-related social needs was considerable in this adult primary care practice. These findings can support a case for integrating health-related social need screening and social care in the delivery of primary care in the United States to advance health equity.

Published: August 2023

Abstract
Background
The days following childbirth are a critical phase in the lives of mothers and newborns. Postpartum length of stay is a critical indicator of the efficiency of health care delivery. This study aims to explore maternal length of hospital stay (LOS) following childbirth and associated factors in a rural health facility in Eritrea.

Methodology
A retrospective study of all mothers who delivered at Nakfa Hospital between 2020 and 2022 was conducted. Sociodemographic, past obstetric, and neonatal factors associated with postpartum LOS were evaluated for both vaginal delivery (VD) and cesarean delivery (CD). The determinants of LOS following VD were explored using negative binomial regression.

Results
A total of 2025 mothers [1975 (97.5%) VD and 50 (2.5%) CD] were included in the study. The median LOS following childbirth was 1 (IQR: 0–1) day for VD and 6 (IQR: 4–8) days for CD. A substantial proportion of mothers were found to have inadequate stays following VD [29% (95% CI: 27–31)], whereas 68% (95% CI: 54-81%) stayed for > 4 days following CD. In this study, VD that were attended by physicians had no inadequate stay, whereas 27.4% of deliveries attended by midwives and 31.3% by associate nurses resulted in inadequate stay (P-value < 0.001). Determinants of LOS following VD were: the presence of maternal complications (IRR = 2.8, 95% CI: 1.6-5, p-value < 0.001), delivery years 2020 and 2021 (IRR = 1.5, 95% CI: 1.2–1.8, p-value < 0.001 and IRR = 1.4, 95% CI: 1.2–1.7, p-value < 0.001, respectively), and delivery hour interval 23:00–7:00 (IRR = 0.8, 95% CI: 0.7–0.9, p-value = 0.03).

Conclusion
A substantial proportion of mothers stay too short post-VD to allow adequate postnatal care, which can have untoward consequences for maternal and child health. Going forward, improved coverage of antenatal care for early diagnosis of maternal complications in pregnancy as well as assessing the level of knowledge and provisions of training and refresher courses for birth attendants should be worked upon. In addition, efforts to conduct studies that explore maternal and health care provider perspectives on LOS should be emphasized.

Published: August 2023

Abstract
Objective
This study compares the effectiveness of administering sublingual misoprostol combined with oxytocin to that of IV tranexamic acid combined with oxytocin to reduce intra and post-operative blood loss in high-risk women for postpartum haemorrhage (PPH) following cesarean section (CS).

Methods
About 315 high-risk pregnant women undergoing CS participated in this trial. They were randomly assigned into three groups; tranexamic group, misoprostol group, and control group, according to the medication given in the operative theatre. All patients received oxytocin intraoperatively. They were assessed regarding intraoperative blood loss, the incidence of PPH, and the reduction in haemoglobin and hematocrit values.

Results
Both tranexamic and misoprostol groups had similar results in reducing intra and post-operative blood loss. However, the reduction in haemoglobin and hematocrit were significantly lower in tranexamic and misoprostol groups compared to the control group (-0.78 ± 0.57 vs. -0.83 ± 0.52 vs. -1.32 ± 0.57 gm/dl, P < 0.001 and − 3.05 ± 1.28 vs. -3.06 ± 1.13 vs. -4.94 ± 1.82%, P < 0.001 respectively). In addition, the estimated blood loss was significantly lower in the tranexamic and misoprostol groups compared to the control group (641.6 ± 271.9 vs. 617.9 ± 207.4 vs. 1002.4 ± 340.7 ml, P < 0.001).

Conclusion
Both tranexamic acid and misoprostol are equally capable of reducing blood loss, but the results were significantly better compared to using oxytocin alone in high-risk patients.
