Effect of Time to Thrombolysis on Clinical Outcomes in Patients With Acute Ischemic Stroke Treated With Tenecteplase Compared to Alteplase: Analysis From the AcT Randomized Controlled Trial

BACKGROUND: The AcT (Alteplase Compared to Tenecteplase) randomized controlled trial showed that tenecteplase is noninferior to alteplase in treating patients with acute ischemic stroke within 4.5 hours of symptom onset. The effect of time to treatment on clinical outcomes with alteplase is well known; however, the nature of this relationship is yet to be described with tenecteplase. We assessed whether the association of time to thrombolysis treatment with clinical outcomes in patients with acute ischemic stroke differs by whether they receive intravenous tenecteplase versus alteplase. METHODS: Patients included were from AcT, a pragmatic, registry-linked, phase 3 randomized controlled trial comparing intravenous tenecteplase to alteplase in patients with acute ischemic stroke. Eligible patients were >18 years old, with disabling neurological deficits, presenting within 4.5 hours of symptom onset, and eligible for thrombolysis. Primary outcome was modified Rankin Scale score 0 to 1 at 90 days. Safety outcomes included 24-hour symptomatic intracerebral hemorrhage and 90-day mortality rates. Mixed-effects logistic regression was used to assess the following: (a) the association of stroke symptom onset to needle time; (b) door (hospital arrival) to needle time with outcomes; and (c) if these associations were modified by type of thrombolytic administered (tenecteplase versus alteplase), after adjusting for age, sex, baseline stroke severity, and site of intracranial occlusion. RESULTS: Of the 1538 patients included in this analysis, 1146 (74.5%; 591 tenecteplase and 555 alteplase) presented within 3 hours versus 392 (25.5%; 196: TNK and 196 alteplase) who presented within 3 to 4.5 hours of symptom onset. Baseline patient characteristics in the 0 to 3 hours versus 3- to 4.5-hour time window were similar, except patients in the 3- to 4.5-hour window had lower median baseline National Institutes of Health Stroke Severity Scale (10 versus 7, respectively) and lower proportion of patients with large vessel occlusion on baseline CT angiography (26.9% versus 18.7%, respectively). Type of thrombolytic agent (tenecteplase versus alteplase) did not modify the association between continuous onset to needle time (Pinteraction=0.161) or door-to-needle time (Pinteraction=0.972) and primary clinical outcome. Irrespective of the thrombolytic agent used, each 30-minute reduction in onset to needle time was associated with a 1.8% increase while every 10 minutes reduction in door-to-needle time was associated with a 0.2% increase in the probability of achieving 90-day modified Rankin Scale score 0 to 1, respectively. CONCLUSIONS: The effect of time to tenecteplase administration on clinical outcomes is like that of alteplase, with faster administration resulting in better clinical outcomes.

A protocol for feasibility of plasma based GeneXpert platform and Dried Blood Spot (DBS) based Abbott platform for HIV-1 viral load testing among the people living with HIV attending ART centers in India

Background HIV-1 Viral load (VL) measures efficiency of the antiretroviral therapy (ART) after treatment initiation and helps to diagnose virological failures at an early stage. Current VL assays require sophisticated laboratory facilities. As well as there are other challenges pertaining to insufficient laboratory access, cold-chain management and sample transportation. Hence the number of HIV-1 VL testing laboratories is inadequate in the resource limited settings. The revised national tuberculosis elimination programme (NTEP) in India has developed a vast network of point of care (PoC) testing facilities for diagnosis of tuberculosis and several GeneXpert platforms are functional under this programme. Both the GeneXpert HIV-1 assay and HIV-1 Abbott real time assay are comparable and GeneXpert HIV-1 assay can be used as PoC for HIV-1 Viral load testing. Also, the dried blood spot (DBS) as a sample type has been considered as a good option for HIV-1 VL testing in hard to reach areas. This protocol is therefore developed to assess the feasibility of integrating HIV-1 VL testing among people living with HIV (PLHIV) attending ART centres using the two public health models under the current programme: 1. HIV-1 VL testing using GeneXpert platform and plasma as a sample type, and 2. HIV-1 VL testing using Abbott m2000 platform and DBS as a sample type. Methods This ethically approved feasibility study will be implemented at two moderate to high burden ART centres where VL testing facility is not available in the town. Under Model-1, arrangements will be made to carry out VL testing on the adjacent GeneXpert facility and under Model-2, DBS will be prepared on site and couriered to identified viral load testing laboratories. In order to assess the feasibility, data will be collected on pretested questionnaire pertaining to number of samples tested for VL testing, number of samples tested for tuberculosis (TB) diagnosis and the turnaround time (TAT). In-depth interviews will be conducted among the service providers at ART centre and different laboratories for addressing any issues regarding the model implementation. Results The proportion of PLHIV tested for VL at ART centres, total TAT for both models including TAT for sample transportation, sample testing and receipt of results as well as proportion of sample rejections and reasons for the same, correlation coefficient between DBS based and plasma based VL testing will be estimated using various statistical tools. Conclusion If found promising, these public health approaches will be helpful for the policy makers and program implementation in scaling up HIV-1 viral load testing within India.
Improvement in cerebral oxygen saturation with sinus conversion during off pump coronary artery bypass graft: A case report

Rationale: Near-infrared spectroscopy (NIRS) is a noninvasive bedside tool for monitoring regional cerebral oxygen saturation (rSO2). The sinus conversion of atrial fibrillation (AF) was shown to be responsible for increasing rSO2. However, the reason for this improvement has not yet been clearly explained. Patient concerns: We report the case of a 73-year-old woman who underwent cardioversion during an off-pump coronary artery bypass under NIRS and live hemodynamic monitoring. Interventions: Unlike previous studies that failed to control and compare all conditions during procedures, this case showed real-time fluctuating hemodynamic and hematological values, such as hemoglobin (Hgb), central venous pressure (CVP), mean arterial pressure (MAP), cardiac index (CI), left ventricular end-diastolic pressure (LVEDP), and SVO2. Outcomes: The rSO2 increased immediately after cardioversion and decreased during the obtuse marginal (OM) graft and after AF was obtained. However, no other hemodynamic data showed the same or opposite directional changes in the rSO2. Lessons: Significant instantaneous changes were observed in rSO2 using NIRS after sinus conversion, without obvious hemodynamic alterations in the systemic circulation or other monitoring values.
How do older women perceive the occupations and activities within their maternal role? Findings from an exploratory survey

Background Participation in meaningful everyday occupations and life-roles is crucial to the health and wellbeing of older adults. However, little is known regarding meaningful life-roles of older women. Although the maternal-role remains meaningful to women throughout their life, previous literature focused on earlier stages of motherhood. Aims To describe the occupations and perceptions within the maternal-role of older women. Materials and method An online survey was distributed via social media. It included closed and open-ended questions regarding the engagement and relatedness of occupations to the maternal-role; and the perceptions of older women towards their maternal-role. Quantitative data was analyzed using descriptive statistics, and thematic analysis was used to analyze data from open-ended questions. Results The survey was answered by 317 community-dwelling older mothers (aged 65–87). High frequency of engagement and relatedness of occupations to the maternal-role were found. Most participants perceived the maternal-role as a never-ending and evolving life role. Seven categories, describing both ’doing’ and ’being’ aspects of the maternal-role, were identified. Conclusion The maternal-role is meaningful to older women. It continues to develop over time, and includes new occupations which have not been central at earlier stages of motherhood. Significance These findings have significant implications for healthcare professionals striving to promote healthy aging by enhancing the participation of older women in meaningful occupations. Further research is needed to broaden the understanding of the unique characteristics of the maternal-role at older age.
Proportion and patterns of ocular disorders among under‐five children in Khartoum State, Sudan: A cross‐sectional study

Early childhood is an important period for children's health and development. In addition to physical wellbeing, healthy development of a child is when social, emotional and educational needs are met. Ocular diseases among children are related to prenatal‐, neonatal‐, or childhood‐underlying causes. Ocular diseases at a young age might significantly affect children's development and eventually interfere with their quality of life. Visual defects and blindness among young children are a major concern, as they have numerous negative impacts on individuals, the community, and the country. Globally, it is estimated that one child goes blind every minute and 60% die within 1–2 years of becoming blind. The majority of blind children are in poor African and Asian countries. Conjunctivitis and refractive errors (REs) are the most common pediatric ocular diseases, whereas congenital cataracts remain the most common treatable blinding disorder in infancy and childhood. Other common pediatrics ocular diseases include retinopathy of prematurity (ROP), optic atrophy, advanced glaucoma, anophthalmos, retinal detachment, keratomalacia with perforation, corneal opacities, and myopia. The detection of ocular diseases is crucial for effective interventions and, therefore, vision screening programs for young children are highly recommended. However, there are barriers in conducting these programs in developing countries due to scarcity of trained professionals and low enrolment in screening programs. As a result, the majority of young children never get an eye examination. The majority of ocular disorders such as amblyopia, unilateral blindness, and strabismus occur at a young age and is the reason why the American Academy of Pediatrics recommends visual screening programs for children younger than 5 years to ensure early detection and appropriate interventions, which, in turn, result in a better quality of life. The objective of this research was to study the epidemiological patterns of ocular morbidity among children younger than 5 years old at three tertiary eye hospitals.
A latent class analysis of the socio-demographic factors and associations with mental and behavioral disorders among Australian children and adolescents

Background Previous studies have shown a relationship between socio-demographic variables and the mental health of children and adolescents. However, no research has been found on a model-based cluster analysis of socio-demographic characteristics with mental health. This study aimed to identify the cluster of the items representing the socio-demographic characteristics of Australian children and adolescents aged 11–17 years by using latent class analysis (LCA) and examining the associations with their mental health. Methods Children and adolescents aged 11–17 years (n = 3152) were considered from the 2013–2014 Young Minds Matter: The Second Australian Child and Adolescent Survey of Mental Health and Wellbeing. LCA was performed based on relevant socio-demographic factors from three levels. Due to the high prevalence of mental and behavioral disorders, the generalized linear model with log-link binomial family (log-binomial regression model) was used to examine the associations between identified classes, and the mental and behavioral disorders of children and adolescents. Results This study identified five classes based on various model selection criteria. Classes 1 and 4 presented the vulnerable class carrying the characteristics of “lowest socio-economic status and non-intact family structure” and “good socio-economic status and non-intact family structure” respectively. By contrast, class 5 indicated the most privileged class carrying the characteristics of “highest socio-economic status and intact family structure”. Results from the log-binomial regression model (unadjusted and adjusted models) showed that children and adolescents belonging to classes 1 and 4 were about 1.60 and 1.35 times more prevalent to be suffering from mental and behavioral disorders compared to their class 5 counterparts (95% CI of PR [prevalence ratio]: 1.41–1.82 for class 1; 95% CI of PR [prevalence ratio]: 1.16–1.57 for class 4). Although children and adolescents from class 4 belong to a socio-economically advantaged group and shared the lowest class membership (only 12.7%), the class had a greater prevalence (44.1%) of mental and behavioral disorders than did class 2 (“worst education and occupational attainment and intact family structure”) (35.2%) and class 3 (“average socio-economic status and intact family structure”) (32.9%). Conclusions Among the five latent classes, children and adolescents from classes 1 and 4 have a higher risk of developing mental and behavioral disorders. The findings suggest that health promotion and prevention as well as combating poverty are needed to improve mental health in particular among children and adolescents living in non-intact families and in families with a low socio-economic status.
Association of neutrophil-to-lymphocyte ratio with clinical, pathological, radiological, laboratory features and disease outcomes of invasive breast cancer patients: A retrospective observational cohort study

Inflammatory conditions play part in the progression of malignancies, and markers signifying growth of these factors can indicate prognosis. Neutrophil-to-lymphocyte (NLR) is used as a marker of subclinical inflammation that may become an integral part of workup to indicate prognosis and associated pathology. This study aims to explore the association of NLR ratio with clinical characteristics, radiological assessment and staging, histopathology, and disease outcomes of breast cancer. A retrospective cohort study was conducted in a tertiary care center to include breast cancer patients that were diagnosed between January 2001 and December 2020. Data including tumor size, lymph nodes, metastasis, histological grading, ER/PR/HER2-neu status, molecular subtypes, clinical staging); nodal findings (sentinel and axillary); pathology from frozen section; and disease outcomes were assessed. Multivariable regression and Kaplan–Meier survival curves were employed to indicate the association of NLR with breast cancer features and disease-free survival. A total of 2050 patients had a median age of 50 years, median NLR levels of 2.14, most common pathology ductal followed by lobular, and most common site of metastasis being lungs followed by bones. Disease-free rate was 7.6%, and a recurrence rate of 1.8%, while 1.6% deaths were reported. NLR was found associated with age, treatment outcomes, tumor size, lymph nodes, metastasis and clinical staging. Other positive correlations were with Ki67 proliferation index, molecular subtypes, and tumor size on frozen section (at transverse and craniocaudal dimensions). Negative correlations were seen with estrogen and progesterone receptors. However, NLR was not found predictable of disease-free survival (P = .160). Significant predictors of disease-free survival were histological grading, ER, PR status, molecular subtype, and Ki67 proliferation index. NLR being a readily available marker has shown novel findings in its association with tumor staging, disease outcomes and characteristics of breast malignancy.
Association between body mass index and posterior spine fusion among patients with adolescent idiopathic scoliosis

Introduction Previous studies have found mixed associations between body mass index (BMI) and adolescent idiopathic scoliosis (AIS) incidence and progression. The aim of this study was to examine the association between BMI and the incidence of posterior spine fusion (PSF) among pediatric patients with AIS. Methods This was a retrospective cohort study of patients diagnosed with AIS at a single large tertiary care center between January 1, 2014 and December 31, 2020. BMI-for-age percentiles were used to categorize BMI into four categories: underweight (<5th percentile), healthy weight (≥5th to <85th percentile), overweight (≥85th to <95th percentile), and obese (≥95th percentile). Chi-square and t-tests were used to compare distributions of baseline characteristics by incident PSF outcome status. Multivariable logistic regression assessed the association between BMI category at baseline and incident PSF adjusting for sex, age at diagnosis, race/ethnicity, health insurance type, vitamin D supplementation, and low vitamin D levels. Results A total of 2,258 patients met the inclusion criteria with 2,113 patients (93.6%) who did not undergo PSF during the study period and 145 patients (6.4%) who did undergo PSF. At baseline, 7.3% of patients were categorized as underweight, 73.2% were healthy weight, 10.2% were overweight, and 9.3% were obese. Compared to those in the healthy weight group, there was no significant association between PSF and being underweight (adjusted odds ratio [AOR] 1.64, 95% CI 0.90–2.99, p = 0.107), being overweight (AOR 1.25, 95% CI 0.71–2.20, p = 0.436), or being obese (AOR 1.19, 95% CI 0.63–2.27, p = 0.594). Conclusions This study did not find a statistically significant association between underweight, overweight, or obese BMI category and incident PSF among patients with AIS. These findings add to the current mixed evidence on the relationship between BMI and surgical risk and may support the recommendation of conservative treatment to patients regardless of BMI.
Earnings and work loss from 5 years before to 5 years after bariatric surgery: A cohort study

Background The personal economic impact of bariatric surgery is not well-described. Objectives To examine earnings and work loss from 5 years before to 5 years after bariatric surgery compared with the general population. Setting Nationwide matched cohort study in the Swedish health care system. Methods Patients undergoing primary bariatric surgery (n = 15,828) and an equal number of comparators from the Swedish general population were identified and matched on age, sex, place of residence, and educational level. Annual taxable earnings (primary outcome) and annual work loss (secondary outcome combining months with sick leave and disability pension) were retrieved from Statistics Sweden. Participants were included in the analysis until the year of study end, emigration or death. Results From 5 years before to 5 years after bariatric surgery, earnings increased for patients overall and in subgroups defined by education level and sex, while work loss remained relatively constant. Bariatric patients and matched comparators from the general population increased their earnings in a near parallel fashion, from 5 years before (mean difference -$3,489 [95%CI -3,918 to -3,060]) to 5 years after surgery (-$4,164 [-4,709 to -3,619]). Work loss was relatively stable within both groups but with large absolute differences both at 5 years before (1.09 months, [95%CI 1.01 to 1.17]) and 5 years after surgery (1.25 months, [1.11 to 1.40]). Conclusions Five years after treatment, bariatric surgery had not reduced the gap in earnings and work loss between surgery patients and matched comparators from the general population.
The relationship between stress and sleep quality: The mediating effect of fatigue and dizziness among patients with cardiovascular disease

Cardiovascular disease is the leading cause of non-noncommunicable disease mortality worldwide. Therefore, this study analyzes the mediating effect of dizziness and fatigue in the relationship between stress and sleep quality in patients with heart disease. This study was conducted on patients with heart disease diagnosed by a cardiologist from December 7, 2021 to August 30, 2022 at the Outpatient Department of Cardiology at Hanyang University Hospital in Guri-si, Gyeonggi-do. To verify the serial multiple mediation effect, serial multiple mediation analysis was performed using SPSS Macro Process Model 6 as the most appropriate verification method for this study. The analysis indicated that the more dizziness a participant experienced, the more severe their physical and psychological fatigue and the poorer their quality of sleep. Also, the more severe the physical fatigue, the worse the psychological fatigue and the worse the quality of sleep. In other words, the more severe the psychological fatigue, the poorer the quality of sleep. In summary, in the relationship in which stress in patients with heart disease affects sleep quality, stress is a variable that directly affects sleep quality, and this means that the stress of patients with heart disease can affect the quality of sleep through the parameters, dizziness and fatigue, sequentially; this research model can thus be considered a partial mediator model. Fatigue in patients with cardiovascular disease had a direct effect on sleep quality, and there was a mediating effect through dizziness and fatigue in the relationship between stress and sleep quality. Therefore, it is necessary to develop a sleep management program that can improve the quality of sleep in patients with cardiovascular disease as well as a nursing intervention plan that can alleviate fatigue and control stress in such patients.
A novel soybean hairy root system for gene functional validation

Agrobacterium rhizogenes-mediated transformation has long been explored as a versatile and reliable method for gene function validation in many plant species, including soybean (Glycine max). Likewise, detached-leaf assays have been widely used for rapid and mass screening of soybean genotypes for disease resistance. The present study combines these two methods to establish an efficient and practical system to generate transgenic soybean hairy roots from detached leaves and their subsequent culture under ex vitro conditions. We demonstrated that hairy roots derived from leaves of two (tropical and temperate) soybean cultivars could be successfully infected by economically important species of root-knot nematodes (Meloidogyne incognita and M. javanica). The established detached-leaf method was further explored for functional validation of two candidate genes encoding for cell wall modifying proteins (CWMPs) to promote resistance against M. incognita through distinct biotechnological strategies: the overexpression of a wild Arachis α-expansin transgene (AdEXPA24) and the dsRNA-mediated silencing of an endogenous soybean polygalacturonase gene (GmPG). AdEXPA24 overexpression in hairy roots of RKN-susceptible soybean cultivar significantly reduced nematode infection by approximately 47%, whereas GmPG downregulation caused an average decrease of 37%. This novel system of hairy root induction from detached leaves showed to be an efficient, practical, fast, and low-cost method suitable for high throughput in root analysis of candidate genes in soybean.
