Hepatitis C (HCV) therapy for HCV mono-infected and HIV-HCV co-infected individuals living in Nepal

BackgroundDespite direct-acting antivirals (DAA), aims to “eradicate” viral hepatitis by 2030 remain unlikely. In Nepal, an expert consortium was established to treat HCV through Nepal earthquakes aftermath offering a model for HCV treatment expansion in a resource-poor setting.Methodology/Principal findingsIn 2015, we established a network of hepatologists, laboratory experts, and community-based leaders at 6 Opioid Substitution Treatment (OST) sites from 4 cities in Nepal screening 838 patients for a treatment cohort of 600 individuals with HCV infection and past or current drug use. During phase 1, patients were treated with interferon-based regimens (n = 46). During phase 2, 135 patients with optimal predictors (HIV controlled, without cirrhosis, low baseline HCV viral load) were treated with DAA-based regimens. During phase 3, IFN-free DAA treatment was expanded, regardless of HCV disease severity, HIV viremia or drug use. Sustained virologic response (SVR) was assessed at 12 weeks.Median age was 37 years and 95.5% were males. HCV genotype was 3 (53.2%) or 1a (40.7%) and 32% had cirrhosis; 42.5% were HIV-HCV coinfected. The intention-to-treat (ITT) SVR rates in phase 2 and 3 were 97% and 81%, respectively. The overall per-protocol and ITT SVR rates were 97% and 85%, respectively. By multivariable analysis, treatment at the Kathmandu site was protective and substance use, treatment during phase 3 were associated with failure to achieve SVR.Conclusions/SignificanceVery high SVR rates may be achieved in a difficult-to-treat, low-income population whatever the patient’s profile and disease severity. The excellent treatment outcomes observed in this real-life community study should prompt further HCV treatment initiatives in Nepal.     

Glycosylation of site-specific glycans of α1-acid glycoprotein and alterations in acute and chronic inflammation

Backgroundα₁-Acid glycoprotein (AGP), an acute phase reactant, is extensively glycosylated at five Asn-linked glycosylation sites. In a number of pathophysiological states, including inflammation, rheumatoid arthritis, and cancer, alterations of Asn-linked glycans (N-glycans) have been reported. We investigated alteration of N-glycans at each of glycosylation sites of AGP in the sera of patients with acute and chronic inflammation.MethodsAGP purified from sera was digested with Glu-C and the liberated glycopeptides were isolated by reverse phase HPLC. N-glycans released with peptide N-glycosidase F and followed by neuraminidase treatment were analyzed by matrix-assisted laser desorption ionization-time of flight mass spectrometry.ResultsSite-specific differences in branching structures were observed among N-glycosylation sites 1, 3, 4 and 5. Within the sera of patients with acute inflammation, increases in bi-antennary and decreases in tri- and tetra-antennary structures were observed, as well as increases in α1,3-fucosylation, at most glycosylation sites. In the sera of patients with chronic inflammation, increased rates of tri-antennary α1,3-fucosylation at sites 3 and 4 and tetra-antennary α1,3-fucosylation at sites 3, 4 and 5 were detected. Although there were no significant differences between acute and chronic sera in site directed branching structures, significant differences of α1,3-fucosylation were detected in tri-antennary at sites 2, 4 and 5 and in tetra-antennary at sites 3 and 4.ConclusionLittle variation in the N-glycan composition of the glycosylation sites of AGP was observed among healthy individuals, while the sera of patients with acute inflammation demonstrated increased numbers of bi-antennary and α1,3-fucosylated N-glycan structures at each glycosylation site.     

Feasibility of allogeneic mesenchymal stem cells in pediatric hypoxic-ischemic encephalopathy: Phase I study

BACKGROUNDHypoxic-ischemic encephalopathy (HIE) is one of the leading causes of death and long-term neurological impairment in the pediatric population. Despite a limited number of treatments to cure HIE, stem cell therapies appear to be a potential treatment option for brain injury resulting from HIE.AIMTo investigate the efficacy and safety of stem cell-based therapies in pediatric patients with HIE.METHODSThe study inclusion criteria were determined as the presence of substantial deficit and disability caused by HIE. Wharton’s jelly-derived mesenchymal stem cells (WJ-MSCs) were intrathecally (IT), intramuscularly (IM), and intravenously administered to participants at a dose of 1 × 10⁶/kg for each administration route twice monthly for 2 mo. In different follow-up durations, the effect of WJ-MSCs administration on HIE, the quality of life, prognosis of patients, and side effects were investigated, and patients were evaluated for neurological, cognitive functions, and spasticity using the Wee Functional Independence Measure (Wee FIM) Scale and Modified Ashworth (MA) Scale. RESULTSFor all participants (n = 6), the mean duration of exposure to hypoxia was 39.17 + 18.82 min, the mean time interval after HIE was 21.83 ± 26.60 mo, the mean baseline Wee FIM scale score was 13.5 ± 0.55, and the mean baseline MA scale score was 35 ± 9.08. Three patients developed only early complications such as low-grade fever, mild headache associated with IT injection, and muscle pain associated with IM injection, all of which were transient and disappeared within 24 h. The treatment was evaluated to be safe and effective as demonstrated by magnetic resonance imaging examinations, electroencephalographies, laboratory tests, and neurological and functional scores of patients. Patients exhibited significant improvements in all neurological functions through a 12-mo follow-up. The mean Wee FIM scale score of participants increased from 13.5 ± 0.55 to 15.17 ± 1.6 points (mean ± SD) at 1 mo (z = - 1.826, P = 0.068) and to 23.5 ± 3.39 points at 12 mo (z = -2.207, P = 0.027) post-treatment. The percentage of patients who achieved an excellent functional improvement (Wee FIM scale total score = 126) increased from 10.71% (at baseline) to 12.03% at 1 mo and to 18.65% at 12 mo post-treatment. CONCLUSIONBoth the triple-route and multiple WJ-MSC implantations were safe and effective in pediatric patients with HIE with significant neurological and functional improvements. The results of this study support conducting further randomized, placebo-controlled studies on this treatment in the pediatric population.     

Randomized Prospective Comparison of Two Protocols for Head-up Tilt Testing in Patients with Normal Heart and Recurrent Unexplained Syncope

BackgroundThis randomized study was aimed to compare the diagnostic value of two head-up tilt testing protocols using sublingual nitroglycerin for provocation in patients with recurrent unexplained syncope and normal heart.MethodsThe patients with normal findings in physical examination, electrocardiography and echocardiography were randomly submitted to one of upright tilt test protocols. The only difference between two protocols was that nitroglycerin was administered after a five minute resting phase in supine position during protocol B. We also considered eighty normal persons as the control group.ResultsOut of 290 patients that underwent tilt testing, 132 patients were in group A versus 158 patients in group B. Both groups had an identical distribution of clinical characteristics. Tilt test was positive in 79 patients in group A (25 in passive phase, 54 in active phase) versus 96 patients in group B (43 in passive phase, 53 in active phase). There was no significant difference between results in two groups (P value = 0.127). Forty cases were tested with protocol A and forty underwent tilt testing with protocol B. Tilt test was positive in 4 cases with protocol A versus 3 cases in protocol B. The positive rates of tilt testing with protocol A was 60% while it was 61% in protocol B. The specificity of testing with protocol A was 90% and it was 92.5% in protocol B.ConclusionsAccording to our data, adding a period of rest and returning to supine position before nitroglycerin administration had no additional diagnostic yield.     

High Titers of Autoantibodies to Glutamate Decarboxylase in Type 1 Diabetes Patients: Epitope Analysis and Inhibition of Enzyme Activity

ObjectiveAutoantibodies to glutamate decarboxylase (GAD65Ab) are found in patients with autoimmune neurological disorders or type 1 diabetes. The correct diagnosis of GAD65Ab-associated neurological disorders is often delayed by the variability of symptoms and a lack of diagnostic markers. We hypothesized that the frequency of neurological disorders with high GAD65Ab titers is significantly higher than currently recognized.MethodsWe analyzed GAD65Ab titer, GAD65 enzyme activity inhibition, and GAD65Ab epitope pattern in a cohort of type 1 diabetes patients (n = 100) and correlated our findings with neurological symptoms and diseases.ResultsOverall, 43% (43/100) of patients had detectable GAD65Ab titers (median = 400 U/mL, range: 142250,000 U/mL). The GAD65Ab titers in 10 type 1 diabetes patients exceeded the 90^th percentile of the cohort (2,000250,000 U/mL). Sera of these 10 patients were analyzed for their GAD65Ab epitope specificity and their ability to inhibit GAD65 enzyme activity in vitro. GAD65Ab of 5 patients inhibited the enzyme activity significantly (by 34-55%). Three patients complained of muscle stiffness and pain, which was documented in 2 of these patients.ConclusionsBased on our findings, we suggest that neurological disorders with high GAD65Ab titers are more frequent in type 1 diabetes patients than currently recognized.

Yaws recurrence in children at continued risk of infection

BackgroundIn yaws-endemic areas, children with Treponema pallidum subsp. pertenue infection may suffer recurrent episodes due to either reinfection or relapse. However, the possibility of infection with other cutaneous ulcer causative agents and difficulties in interpreting standard laboratory results challenges the estimation of yaws recurrence rates.MethodsWe estimated the rates of yaws recurrences in the Lihir Island (Papua New Guinea) using two approaches: passive surveillance based on a retrospective screening of electronic medical records of cutaneous ulcers diagnosed using serological testing between 2005 and 2016, and active surveillance conducted during a cross-sectional prevalence study which included PCR analyses of ulcers of all suspected cases of yaws. The risk of recurrent infection was assessed based on data from the passive surveillance analysis and using two Cox regression models (crude and multivariate), stratified by year of index episode. Data gathered from the active surveillance was used to characterize the recurrences and no hypothesis testing was performed.ResultsThe electronic medical records included 6,125 patients (7,889 ulcer episodes) with documented serological results of cutaneous ulcers of which1,486 were diagnosed with yaws. Overall, 1,246/6,125 patients (20.3%) presented more than once with a cutaneous ulcer, and 103/1,486 (6.7%) patients had multiple episodes of yaws. The risk of yaws recurrence significantly increased with age and was higher in patients with ≥3 recurrent episodes. In the active surveillance, we identified 50 individuals with recurrent cutaneous ulcer that had PCR results available for both the index and recurrent episode. Of 12 individuals with T. pallidum in the index ulcer, 8 (66%) had T. pallidum in subsequent assessments, relapse related to macrolide-resistance was identified in two of these cases.ConclusionsOur results confirm the need for active follow-up of yaws patients after treatment, particularly children and individuals with a history of recurrence.     

The effects of geolocators on return rates,condition, and breeding success in Common Sandpipers Actitis hypoleucos

ABSTRACT

Capsule: Fitting geolocators to Common Sandpipers Actitis hypoleucos did not affect their return rates, return dates, body condition or reproductive success, but did cause leg injuries in some individuals.

Aims: To investigate the effect of fitting geolocators to Common Sandpipers on their return rates and timing, the condition in which they return and their subsequent breeding success.

Methods: We fitted geolocators to colour-ringed Common Sandpipers and monitored them throughout the breeding seasons prior to migration and following return from their wintering grounds. We then compared return rate, return date, change in body condition, hatching success, and fledging success between birds with and without the tags. We also fitted a number of smaller geolocators to wintering individuals in Africa and compared their return rates with a control group.

Results: We found no significant differences between birds with and without geolocators in any of the variables measured. However, several individuals fitted with the larger tags were found to have incurred leg injuries.

Conclusion: Our study highlights the need for complete transparency when reporting the effects of geolocators and shows the importance of continuous monitoring of individuals when carrying out tracking studies.     

Socioeconomic predictors of suicide risk among cancer patients in the United States: A population-based study

ObjectiveTo assess the socioeconomic predictors of suicide risk among cancer patients in the United States.MethodsCancer patients available within Surveillance, Epidemiology and End Results (SEER) database who were diagnosed between 2000–2010 have been reviewed. Linkage analysis to Census 2000 SF files was conducted to determine area-based socioeconomic attributes. Observed/ Expected ratios were calculated for the overall cohort as well as for clinically and socioeconomically defined subgroups. “Observed” is the number of observed completed suicide cases in the studied cohort; while “Expected” is the number of completed suicide cases in a demographically similar cohort within the United States and within the same period of time.ResultsThe current study reviews a total of 3,149,235 cancer patients (diagnosed 2000–2010) within the SEER database. Regarding socioeconomic county attributes, higher risk of suicide seems to be associated with lower educational attainment (O/E for counties with > 20% individuals with less than high school education: 1.41; 95% CI: 1.35–1.47), poverty rates (O/E for counties with > 5% individuals below poverty line: 1.39; 95% CI: 1.34–1.43), unemployment rates (O/E for counties with >5% families below poverty line: 1.36; 95% CI: 1.31–1.41) and less people living in urban areas (O/E for counties with < 50% individuals living in urban areas: 1.63; 95% CI: 1.50–1.77). On the other hand, risk of suicide seems to be inversely related to a higher representation of foreign-born individuals (O/E for counties with < 5% foreign-born individuals: 1.56; 95% CI: 1.47–1.65); and inversely related to a higher representation with recent immigrants to the US (O/E for counties with < 5% recent immigrants: 1.33; 95% CI: 1.29–1.38).ConclusionsCancer patients living in a socioeconomically vulnerable environment (lower educational status, poverty, and unemployment) seem to have higher suicide risk compared to other cancer patients.     

GRM7 polymorphisms are not associated with ischemic stroke in Iranian population

Abstract

Objectives: Ischemic stroke is the main neurological cause of acquired incapability in adults and a prominent cause of mortality. Several association studies have been conducted to explore the role of candidate genes in this neurological condition.

Methods: In the present study, we aimed at identification of association between Glutamate Metabotropic Receptor 7 (GRM7) and risk of ischemic stroke in Iranian population. Two intronic variants within this gene (rs6782011 and rs779867) were genotyped in 318 sporadic ischemic stroke cases and 300 unrelated, healthy controls individuals.

Results: No significant difference was found in allele, genotype or haplotype frequencies of these SNPs between cases and controls after correction for multiple comparisons.

Conclusion: Consequently, the assessed GRM7 variants are not implicated in risk of ischemic stroke in Iranian population.     

Primary Hyperparathyroidism is Associated With subclinical Peripheral Neural Alterations

ObjectiveSome case reports have suggested primary hyperparathyroidism (PHPT) and peripheral polyneuropathy (PPN) are associated; however, there are no reports of studies examining this possible relationship. The aim of this study was to evaluate peripheral nerve conduction in subjects with PHPT.MethodsThe study involved 17 patients with PHPT. Mean patient age was 60.5 ± 12.9 years, serum calcium concentration was 11.5 ± 1.0 mg/dL, and the serum parathyroid hormone (PTH) level was 315 ± 569 pg/dL. The control group comprised 17 individuals without PHPT. The mean age of controls was 60.8 ± 12.5 years and the serum calcium concentration was 9.8 ± 0.3 mg/dL. Motor and sensory nerve conduction was assessed by electroneurography (ENG).ResultsThe following ENG parameters differed significantly between the PHPT and control groups: right (R) sural sensory nerve action potential conduction velocity (52.7 ± 6.3 m/s versus 58.0 ± 8.0 m/s; P = .041); R median compound muscle action potential (CMAP) amplitude (7.4 ± 1.6 mV versus 8.9 ± 1.7 mV; P = .002); R median CMAP latency (4.3 ± 1.2 ms versus 3.6 ± 0.6 ms; P = .032); R tibial CMAP latency (4.2 ± 1.1 ms versus 3.3 ± 0.4 ms; P = .001). The neurological examination was normal in all patients.ConclusionOur data demonstrate an association between PHPT and peripheral neurological alterations, consistent with subclinical sensory-motor PPN.

Behavioural alterations are independent of sickness behaviour in chronic experimental Chagas disease

The existence of the nervous form of Chagas disease is a matter of discussion since Carlos Chagas described neurological disorders, learning and behavioural alterations in Trypanosoma cruzi-infected individuals. In most patients, the clinical manifestations of the acute phase, including neurological abnormalities, resolve spontaneously without apparent consequence in the chronic phase of infection. However, chronic Chagas disease patients have behavioural changes such as psychomotor alterations, attention and memory deficits, and depression. In the present study, we tested whether or not behavioural alterations are reproducible in experimental models. We show that C57BL/6 mice chronically infected with the Colombian strain of T. cruzi (150 days post-infection) exhibit behavioural changes as (i) depression in the tail suspension and forced swim tests, (ii) anxiety analysed by elevated plus maze and open field test sand and (iii) motor coordination in the rotarod test. These alterations are neither associated with neuromuscular disorders assessed by the grip strength test nor with sickness behaviour analysed by temperature variation sand weight loss. Therefore, chronically T. cruzi-infected mice replicate behavioural alterations (depression and anxiety) detected in Chagas disease patients opening an opportunity to study the interconnection and the physiopathology of these two biological processes in an infectious scenario.     

Leishmania-HIV Co-infection: Clinical Presentation and Outcomes in an Urban Area in Brazil

BackgroundVisceral leishmaniasis (VL) is an emerging condition affecting HIV-infected patients living in Latin America, particularly in Brazil. Leishmania-HIV coinfection represents a challenging diagnosis because the clinical picture of VL is similar to that of other disseminated opportunistic diseases. Additionally, coinfection is related to treatment failure, relapse and high mortality.ObjectiveTo assess the clinical-laboratory profile and outcomes of VL-HIV-coinfected patients using a group of non HIV-infected patients diagnosed with VL during the same period as a comparator.MethodsThe study was conducted at a reference center for infectious diseases in Brazil. All patients with suspected VL were evaluated in an ongoing cohort study. Confirmed cases were divided into two groups: with and without HIV coinfection. Patients were treated according to the current guidelines of the Ministry of Health of Brazil, which considers antimony as the first-choice therapy for non HIV-infected patients and recommends amphotericin B for HIV-infected patients. After treatment, all patients with CD4 counts below 350 cells/mm³ received secondary prophylaxis with amphotericin B.ResultsBetween 2011 and 2013, 168 patients with suspected VL were evaluated, of whom 90 were confirmed to have VL. In total, 51% were HIV coinfected patients (46 patients). HIV-infected patients had a lower rate of fever and splenomegaly compared with immunocompetent patients. The VL relapse rate in 6 months was 37% among HIV-infected patients, despite receiving secondary prophylaxis. The overall case-fatality rate was 6.6% (4 deaths in the HIV-infected group versus 2 deaths in the non HIV-infected group). The main risk factors for a poor outcome at 6 months after the end of treatment were HIV infection, bleeding and a previous VL episode.ConclusionAlthough VL mortality rates among HIV-infected individuals are close to those observed among immunocompetent patients treated with amphotericin B, HIV coinfection is related to a low clinical response and high relapse rates within 6 months.     

Adiponectin gene polymorphisms are associated with increased susceptibility to diabetic peripheral neuropathy

Abstract

Background: Adiponectin (ADP) polymorphisms associated with diabetes mellitus in several populations. However, no previous studies have investigated its association with diabetic peripheral neuropathy (DPN). Our study examined the association between ADP-linked SNPs and DPN susceptibility.

Methods: We randomly recruited 160 diabetes mellitus (DM) patients and 80 healthy individuals.

Results: The C allele of rs3821799 increased DPN susceptibility. In normal individuals, GG of rs3774261 carriers had 7.1 times higher DPN susceptibility than AA carriers. The haplotype analyzes indicated CGG might increase DPN susceptibility.

Conclusion: Our study demonstrated that ADP gene polymorphisms are associated with the susceptibility to DPN.

The methylation status of TNF-α and SOCS3 promoters and the regulation of these gene expressions in patients with Behçet’s disease

Abstract

Introduction: The aim of this study was to evaluate the methylation status of TNF-α and SOCS3 promoters in patients with BD and compare them with a healthy group.

Method: This was a case–control study, in which 47 subjects with BD and 61 individuals as the control participated. Blood samples were collected from all the participants. Then, PBMCs were isolated using the Ficoll method and methylation of considered sites was investigated using the qMS-PCR technique after DNA extraction by the rapid genomic DNA extraction method and its analysis with Nano-drop.

Results: The methylation and expression of TNF-α showed that the methylation level significantly declined in the patient in comparison with the healthy (p?<?0.05). Moreover, the results on the mean expression showed that it significantly increased in the patient group, as compared with the healthy group (p?<?0.05). In addition, the expression of the SOCS3 gene was not significantly different between the patients and healthy subjects while the level of SOCS3 methylation was significantly higher in the patient group than that in the healthy group (p?<?0.05).

Discussion: The present study revealed that the gene expression of TNF-alpha increased in BD patients, suggesting that TNF-alpha likely has a role in the pathogenesis of BD.     

Copy number variation-based gene set analysis reveals cytokine signalling pathways associated with psychiatric comorbidity in patients with inflammatory bowel disease

BackgroundRecent studies discovered many genetic variants associated with both psychiatric and inflammatory disorders, but the role of genetic factors in the development of psychiatric comorbidity (PC) in inflammatory bowel disease (IBD) is underexplored. Particularly, it has been shown that some of the genetic variants have been linked to the concentrations of circulating cytokines and symptoms of the inflammatory cytokine-associated depression. We analysed genomic features of individuals with IBD by comparing IBD patients with PC with those who have IBD but without PC. We hypothesized that cytokine related signalling pathways may be significantly associated with the psychiatric comorbidity in patients with IBD.MethodsIndividuals enrolled in the Manitoba IBD Cohort Study were separated to two groups accordingly to the presence of PC. A sample set comprising 97 IBD individuals with PC (IBD + PC) and 146 IBD individuals without PC (IBD) was first used to identify copy number variations (CNVs) from genome-wide genetic data using three different detection algorithms. IBD + PC and IBD groups were compared by the number of CNVs overlapping each gene; deletions and duplications were analysed separately. Gene set overrepresentation analysis was then conducted using CNV-overlapped genes and the candidate gene sets of neurological and immunological relevance.ResultsMedium-sized CNV (size between 100 and 500 kilobase pairs)-burden is significantly higher in IBD + PC than IBD groups. Gene-based CNV association analysis did not show significant differences between the two IBD groups. Gene set overrepresentation analysis demonstrated the significant enrichment of gene sets related to cytokine signalling pathways by the genes overlapped by deletions in the IBD individuals with PC.ConclusionOur results confirm the role of cytokine signalling pathways in the development of PC in IBD. Additionally, our results warrant further study with a larger sample size focusing on cytokine SNPs to further understand the relationship between inflammatory and psychiatric disorders.     

Identification of serum miR-378 and miR-575 as diagnostic indicators and predicting surgical prognosis in human epilepsy

BackgroundEpilepsy (EP) is a common neurological disorder which is characterized by excessive abnormal synchronization of neuronal discharges in the brain due to chronic recurrent seizures of multiple etiologies. Variety of microRNAs have been associated with the occurrence and development of EP. This study aimed to determine the aberrant expression of miR-378 and miR-575 in EP patients to validate their potential to distinguish EP from healthy patients.MethodsRT-qPCR was used to determine the expressions of miR-378 and miR-575 from serum specimens of 106 EP and 103 control individuals. Clinical indicators between EP patients and controls were assessed. Based on surgical outcome, EP patients were further divided into Engel I-IV EP. The potentials of miR-378 and miR-575 in discriminating EP from healthy participants and predicting surgical prognosis were calculated by receiver operating characteristic (ROC) analysis.ResultsWe found the miR-378 and miR-575 were significantly declined (P<0.001) in Engel I-II and III-IV EP patients with no difference in clinical parameters compared. Moreover, miR-378 and miR-575 displayed high sensitivity, specificity, and accuracy in distinguishing EP patients and predicting surgical outcomes. Moreover, after surgical treatment, miR-378 and miR-575 levels were increased compared with those at admission, suggesting their potentials in treatment response.ConclusionsmiR-378 and miR-575 could be utilized as novel and non-invasive serum biomarkers in discriminating EP from healthy controls and predicting surgical outcome, shedding new insights on epileptogenesis and EP treatment.     

Outcomes of Adult In-Hospital Cardiac Arrest Treated with Targeted Temperature Management: A Retrospective Cohort Study

AimTargeted temperature management (TTM) for in-hospital cardiac arrest (IHCA) is given different recommendation levels within international resuscitation guidelines. We aimed to identify whether TTM would be associated with favourable outcomes following IHCA and to determine which factors would influence the decision to implement TTM.MethodsWe conducted a retrospective observational study in a single medical centre. We included adult patients suffering IHCA between 2006 and 2014. We used multivariable logistic regression analysis to evaluate associations between independent variables and outcomes.ResultsWe included a total of 678 patients in our analysis; only 22 (3.2%) patients received TTM. Most (81.1%) patients met at least one exclusion criteria for TTM. In all, 144 (21.2%) patients survived to hospital discharge; among them, 60 (8.8%) patients displayed favourable neurological status at discharge. TTM use was significantly associated with favourable neurological outcome (OR: 3.74, 95% confidence interval [CI]: 1.19–11.00; p-value = 0.02), but it was not associated with survival (OR: 1.41, 95% CI: 0.54–3.66; p-value = 0.48). Arrest in the emergency department was positively associated with TTM use (OR: 22.48, 95% CI: 8.40–67.64; p value < 0.001) and having vasopressors in place at the time of arrest was inversely associated with TTM use (OR: 0.08, 95% CI: 0.004–0.42; p-value = 0.02).ConclusionTTM might be associated with favourable neurological outcome of IHCA patients, irrespective of arrest rhythms. The prevalence of proposed exclusion criteria for TTM was high among IHCA patients, but these factors did not influence the use of TTM in clinical practice or neurological outcomes after IHCA.
