Abstract
Background
Host resilience (HR) to parasites can affect the performance of animals. Therefore, the aim of this study was to present a detailed investigation of the genetic mechanisms of HR to ticks (TICK), gastrointestinal nematodes (GIN), and Eimeria spp. (EIM) in Nellore cattle that were raised under natural infestation and a prophylactic parasite control strategy. In our study, HR was defined as the slope coefficient of body weight (BW) when TICK, GIN, and EIM burdens were used as environmental gradients in random regression models. In total, 1712 animals were evaluated at five measurement events (ME) at an average age of 331, 385, 443, 498, and 555 days, which generated 7307 body weight (BW) records. Of the 1712 animals, 1075 genotyped animals were used in genome-wide association studies to identify genomic regions associated with HR.

Results
Posterior means of the heritability estimates for BW ranged from 0.09 to 0.54 across parasites and ME. The single nucleotide polymorphism (SNP)-derived heritability for BW at each ME ranged from a low (0.09 at ME.331) to a moderate value (0.23 at ME.555). Those estimates show that genetic progress can be achieved for BW through selection. Both genetic and genomic associations between BW and HR to TICK, GIN, and EIM confirmed that parasite infestation impacted the performance of animals. Selection for BW under an environment with a controlled parasite burden is an alternative to improve both, BW and HR. There was no impact of age of measurement on the estimates of genetic variance for HR. Five quantitative trait loci (QTL) were associated with HR to EIM but none with HR to TICK and to GIN. These QTL contain genes that were previously shown to be associated with the production of antibody modulators and chemokines that are released in the intestinal epithelium.

Conclusions
Selection for BW under natural infestation and controlled parasite burden, via prophylactic parasite control, contributes to the identification of animals that are resilient to nematodes and Eimeria ssp. Although we verified that sufficient genetic variation existed for HR, we did not find any genes associated with mechanisms that could justify the expression of HR to TICK and GIN.

Abstract
Background
Only few data have been published on Helicobacter pylori infection in adolescents in Sub-Saharan Africa, including Sudan. The aim of the present study was to investigate the prevalence and associated factors of H. pylori infection in asymptomatic adolescents schoolchildren (aged 10–19 years) in Sudan.

Methods
A cross-sectional study was conducted from October to November 2022. The participants’ sociodemographic and clinical characteristics were assessed using a questionnaire. The participants underwent a rapid H. pylori antibody test for the detection of H. pylori antibodies. Multivariate regression analyses were performed.

Results
Of the 368 enrolled adolescents, 155 (42.1%) and 213 (57.9%) were boys and girls, respectively. The median (interquartile range [IQR]) age of the total sample was 15.2 years (14.0‒16.4 years). The overall prevalence of H. pylori infection was 8.4%. In the multivariable regression analyses, only the female adolescents (adjusted odds ratio [AOR], 3.04; 95% confidence interval [CI], 1.24‒7.44) were associated with H. pylori infection. Age, parental education and occupation, and body mass index were not associated with contracting H. pylori infection.

Conclusion
H. pylori infection was detected in one of 10 adolescents in Northern Sudan. Female adolescents were at a higher risk of contracting H. pylori infection. The introduction of interventional health programs such as awareness campaigns and improving personal hygiene could lead to the reduction of the risk of H. pylori infection at early ages, especially in girls, and ensure that adolescents are healthy in their present and later lives.

Abstract
Background
Unilateral laminotomy with bilateral spinal canal decompression has gained popularity recently.

Aim
To systematically review the literature of unilateral laminotomy with bilateral spinal canal decompression for lumbar spinal stenosis (LSS) aiming to assess outcomes and complications of the different techniques described in literature.

Methods
On August 7, 2022, Pubmed and EMBASE were searched by 2 reviewers independently, and all the relevant studies published up to date were considered based on predetermined inclusion and exclusion criteria. The subject headings “unilateral laminotomy”, “bilateral decompression” and their related key terms were used. The Preferred Reporting Item for Systematic Reviews and Meta-Analyses statement was used to screen the articles.

Results
A total of seven studies including 371 patients were included. The mean age of the patients was 69.0 years (range: 55–83 years). The follow up duration ranged from 1 to 3 years. Rate of postoperative pain and functional improvement was favorable based on VAS, JOA, JOABPEQ, RMDW, ODI and SF-36, for example improved from a range of 4.2–7.5 preoperatively on the VAS score to a range of 1.4–3.0 postoperatively at the final follow up. Insufficient decompression was noted in 3% of the reported cases. The overall complication rate was reported at 18–20%, with dural tear at 3.6–9% and hematoma at 0–4%.

Conclusion
Unilateral laminotomy with bilateral decompression has favorable short- and mid-term pain and functional outcomes with low recurrence and complication rates. This, however, needs to be further confirmed in larger, long-term follow-up, prospective, comparative studies between open, and minimally invasive techniques.

Published: November 2023

Abstract
Background
Nursing students often find bioscience courses, such as pathophysiology, challenging. Utilizing Twitter to provide concise course content and answer students’ questions before exams may be beneficial. The objective of this study was to determine if using Twitter can improve nursing students’ academic performance and satisfaction with pathophysiology courses.

Methods
A post-test, two-group quasi-experimental research design was employed in this study. It involved second-year Bachelor of Nursing students participating in a pathophysiology course at the College of Nursing, Sultan Qaboos University, in Muscat, Oman. Seventy-three second-year Bachelor of Nursing students participated in the pathophysiology course; 50 students opted to use Twitter, forming the experimental group, while the remaining 23, who chose not to use Twitter, formed the control group. We used Twitter to provide concise course content for the pathophysiology course and conduct one-hour question-and-answer sessions the night before exams. Academic performance was assessed through examination scores, and student satisfaction levels with Twitter was measured using five-point Likert scale questionnaires. Data were analyzed using Mann-Whitney and t-tests.

Results
Although there was no significant difference in final exam scores between the experimental and control groups, survey results showed that students were generally satisfied with the incorporation of Twitter in the pathophysiology course, including the question-and-answer sessions.

Conclusions
The findings suggest that Twitter can serve as a valuable tool for enhancing nursing student satisfaction with the pathophysiology course.
Effect of intermittent Pringle maneuver on perioperative outcomes and long-term survival following liver resection in patients with hepatocellular carcinoma: a meta-analysis and systemic review
Authors: Hu Lingbo , Wang Aidong , Qiao Yingli , Huang Xiandan 
Published: November 2023

Abstract
Background
Intermittent Pringle maneuver (IPM) is commonly used to control bleeding during liver resection. IPM can cause ischemia–reperfusion injury, which may affect the prognosis of patients with hepatocellular carcinoma (HCC). The present meta-analysis was conducted to evaluate the effect of IPM use on perioperative outcomes and long-term survival in patients with HCC.

Methods
A systemic literature search was performed in the PubMed, Embase, Web of Science, and Cochrane Library databases to identify randomized controlled trials and retrospective studies that compared the effect of IPM with no Pringle maneuver during liver resection in patients with HCC. Hazard ratio (HR), risk ratio, standardized mean difference, and their 95% confidence interval (CI) values were calculated based on the type of variables.

Results
This meta-analysis included nine studies comprising one RCT and eight retrospective studies and involved a total of 3268 patients. Perioperative outcomes, including operation time, complications, and length of hospital stay, except for blood loss, were comparable between the two groups. After removing the studies that led to heterogeneity, the results showed that IPM was effective in reducing blood loss. Five studies reported overall survival (OS) and disease-free survival (DFS) data and eight studies reported perioperative outcomes. No significant difference in OS and DFS was observed between the two groups (OS: HR, 1.01; 95% CI, 0.85–1.20; p = 0.95; DFS: HR, 1.01; 95% CI, 0.88–1.17; p = 0.86).

Conclusion
IPM is a useful technique to control blood loss during liver resection and does not affect the long-term survival of patients with HCC.

Abstract
Background
Patients with steroid-refractory acute graft-versus-host disease (aGvHD) not tolerating/responding to ruxolitinib (RR-aGvHD) have a dismal prognosis.

Methods
We retrospectively assessed real-world outcomes of RR-aGvHD treated with the random-donor allogeneic MSC preparation MSC-FFM, available via Hospital Exemption in Germany. MSC-FFM is provided as frozen cell dispersion for administration as i.v. infusion immediately after thawing, at a recommended dose of 1–2 million MSCs/kg body weight in 4 once-weekly doses. 156 patients, 33 thereof children, received MSC-FFM; 5% had Grade II, 40% had Grade III, and 54% had Grade IV aGvHD. Median (range) number of prior therapies was 4 (1–10) in adults and 7 (2–11) in children.

Results
The safety profile of MSC-FFM was consistent with previous reports for MSC therapies in general and MSC-FFM specifically. The overall response rate at Day 28 was 46% (95% confidence interval [CI] 36–55%) in adults and 64% (45–80%) in children; most responses were durable. Probability of overall survival at 6, 12 and 24 months was 47% (38–56%), 35% (27–44%) and 30% (22–39%) for adults, and 59% (40–74%), 42% (24–58%) and 35% (19–53%) for children, respectively (whole cohort: median OS 5.8 months).

Conclusion
A recent real-world analysis of outcomes for 64 adult RR-aGvHD patients not treated with MSCs reports survival of 20%, 16% and 10% beyond 6, 12 and 24 months, respectively (median 28 days). Our data thus suggest effectiveness of MSC-FFM in RR-aGvHD.
Microglia/macrophages are ultrastructurally altered by their proximity to spinal cord injury in adult female mice

Published: November 2023

AbstractTraumatic spinal cord injury can cause immediate physical damage to the spinal cord and result in severe neurological deficits. The primary, mechanical tissue damage triggers a variety of secondary damage mechanisms at the injury site which significantly contribute to a larger lesion size and increased functional damage. Inflammatory mechanisms which directly involve both microglia (MG) and monocyte-derived macrophages (MDM) play important roles in the post-injury processes, including inflammation and debris clearing. In the current study, we investigated changes in the structure and function of MG/MDM in the injured spinal cord of adult female mice, 7 days after a thoracic contusion SCI. With the use of chip mapping scanning electron microscopy, which allows to image large samples at the nanoscale, we performed an ultrastructural comparison of MG/MDM located near the lesion vs adjacent regions to provide novel insights into the mechanisms at play post-injury. We found that MG/MDM located near the lesion had more mitochondria overall, including mitochondria with and without morphological alterations, and had a higher proportion of altered mitochondria. MG/MDM near the lesion also showed an increased number of phagosomes, including phagosomes containing myelin and partiallydigested materials. MG/MDM near the injury interacted differently with the spinal cord parenchyma, as shown by their reduced number of direct contacts with synaptic elements, axon terminals and dendritic spines. In this study, we characterized the ultrastructural changes of MG/MDM in response to spinal cord tissue damage in mice, uncovering changes in phagocytic activity, mitochondrial ultrastructure, and inter-cellular interactions within the spinal cord parenchyma.

Abstract
Background
Influenza A virus (IAV) is the only influenza virus causing flu pandemics (i.e., global epidemics of flu disease). Influenza (the flu) is a highly contagious disease that can be deadly, especially in high-risk groups. Worldwide, these annual epidemics are estimated to result in about 3 to 5 million cases of severe illness and in about 290,000 to 650,000 respiratory deaths. We intend to reveal the effect of IAV infection on the host′s metabolism, immune response, and neurotoxicity by using a mouse IAV infection model.

Methods
51 metabolites of murine blood plasma (33 amino acids/amino acid derivatives (AADs) and 18 metabolites of the tryptophan pathway) were analyzed by using Ultra-High-Performance Liquid Chromatography-Mass Spectrometry with Electrospray Ionization at the acute (7 days post-infection (dpi)), resolution (14 dpi), and recovery (21 dpi) stages of the virus infection in comparison with controls.

Results
Among the 33 biogenic amino acids/AADs, the levels of five amino acids/AADs (1-methylhistidine, 5-oxoproline, α-aminobutyric acid, glutamine, and taurine) increased by 7 dpi, whereas the levels of ten amino acids/AADs (4-hydroxyproline, alanine, arginine, asparagine, cysteine, citrulline, glycine, methionine, proline, and tyrosine) decreased. By 14 dpi, the levels of one AAD (3-methylhistidine) increased, whereas the levels of five amino acids/AADs (α-aminobutyric acid, aminoadipic acid, methionine, threonine, valine) decreased. Among the 18 metabolites from the tryptophan pathway, the levels of kynurenine, quinolinic acid, hydroxykynurenine increased by 7 dpi, whereas the levels of indole-3-acetic acid and nicotinamide riboside decreased.

Conclusions
Our data may facilitate understanding the molecular mechanisms of host responses to IAV infection and provide a basis for discovering potential new mechanistic, diagnostic, and prognostic biomarkers and therapeutic targets for IAV infection.

Abstract
Background
Audit and feedback (A&F) is among the most widely used implementation strategies, providing healthcare professionals with summaries of their practice performance to prompt behaviour change and optimize care. Wide variability in effectiveness of A&F has spurred efforts to explore why some A&F interventions are more effective than others. Unpacking the variability of the content of A&F interventions in terms of their component behaviours change techniques (BCTs) may help advance our understanding of how A&F works best. This study aimed to systematically specify BCTs in A&F interventions targeting healthcare professional practice change.

Methods
We conducted a directed content analysis of intervention descriptions in 287 randomized trials included in an ongoing Cochrane systematic review update of A&F interventions (searched up to June 2020). Three trained researchers identified and categorized BCTs in all trial arms (treatment & control/comparator) using the 93-item BCT Taxonomy version 1. The original BCT definitions and examples in the taxonomy were adapted to include A&F-specific decision rules and examples. Two additional BCTs (‘Education (unspecified)’ and ‘Feedback (unspecified)’) were added, such that 95 BCTs were considered for coding.

Results
In total, 47/95 BCTs (49%) were identified across 360 treatment arms at least once (median = 5.0, IQR = 2.3, range = 1-29). The most common BCTs were ‘Feedback on behaviour’ (present 89% of the time; e.g. feedback on drug prescribing), ‘Instruction on how to perform the behaviour’ (71%; e.g. issuing a clinical guideline), ‘Social comparison’ (52%; e.g. feedback on performance of peers), ‘Credible source’ (41%; e.g. endorsements from respected professional body), and ‘Education (unspecified)’ (31%; e.g. giving a lecture to staff). A total of 130/287 (45%) control/comparator arms contained at least one BCT (median = 2.0, IQR = 3.0, range = 0–15 per arm), of which the most common were identical to those identified in treatment arms.

Conclusions
A&F interventions to improve healthcare professional practice include a moderate range of BCTs, focusing predominantly on providing behavioural feedback, sharing guidelines, peer comparison data, education, and leveraging credible sources. We encourage the use of our A&F-specific list of BCTs to improve knowledge of what is being delivered in A&F interventions. Our study provides a basis for exploring which BCTs are associated with intervention effectiveness.

Published: November 2023

AbstractBackgroundNumerous conditions are grouped under the generic term exercise‐induced leg pain (EILP), yet clear diagnostic guidelines are lacking. This scoping review was conducted to clarify the definition and diagnostic criteria of nine commonly occurring EILP conditions.
MethodsThree online databases were searched from inception to April 2022 for any English language original manuscripts identifying, describing, or assessing the clinical presentation and diagnostic criteria of the nine most common conditions that cause EILP. We included manuscripts considering all adults with any reported diagnostic criteria for EILP in any setting. Methodological quality was assessed using the Mixed Method Appraisal tool. Condition definitions were identified and categorised during data charting. Twenty‐five potential elements of the history, 24 symptoms, 41 physical signs, 21 investigative tools, and 26 overarching diagnostic criteria, were identified and coded as counts of recommendation per condition, alongside qualitative analysis of the clinical reasoning. Condition definitions were constructed with 11 standardised elements based on recent consensus exercises for other conditions.
ResultsOne hundred nineteen retained manuscripts, of which 18 studied multiple conditions, had a median quality of 2/5. A combination of the history, pain location, symptoms, physical findings, and investigative modalities were fundamental to identify each sub‐diagnosis alongside excluding differentials. The details differed markedly for each sub‐diagnosis. Fifty‐nine manuscripts included data on chronic exertional compartment syndrome (CECS) revealing exertional pain (83% history), dull aching pain (76% symptoms), absence of physical signs (78% physical findings) and elevated intercompartment pressure (93% investigative modality). Twenty‐one manuscripts included data on medial tibial stress syndrome (MTSS), revealing persistent pain upon discontinuation of activity (81% history), diffuse medial tibial pain (100% pain location), dull ache (86% symptoms), diffuse tenderness (95% physical findings) and MRI for exclusion of differentials (62% investigative modality). Similar analyses were performed for stress fractures (SF, n = 31), popliteal artery entrapment syndrome (PAES, n = 22), superficial peroneal nerve entrapment syndrome (SPNES, n = 15), lumbar radiculopathy (n = 7), accessory/low‐lying soleus muscle syndrome (ALLSMS, n = 5), myofascial tears (n = 3), and McArdle's syndrome (n = 2).
ConclusionInitial diagnostic frameworks and definitions have been developed for each condition of the nine most common conditions that cause EILP, suitable for clinical consideration and consensus confirmation.
