Clinical Presentations and Outcomes of Children in Canada With Recurrent Invasive Pneumococcal Disease From the IMPACT Surveillance Network

Supplemental Digital Content is available in the text. Background: Invasive pneumococcal disease due to Streptococcus pneumoniae can cause mortality and severe morbidity due to sepsis, meningitis and pneumonia, particularly in young children and the elderly. Recurrent invasive pneumococcal disease is rare yet serious sequelae of invasive pneumococcal disease that is associated with the immunocompromised and leads to a high mortality rate. Method: This retrospective study reviewed recurrent invasive pneumococcal disease cases from the Canadian Immunization Monitoring Program, ACTive (IMPACT) between 1991 and 2019, an active network for surveillance of vaccine-preventable diseases and adverse events following immunization for children ages 0–16 years. Data were collected from 12 pediatric tertiary care hospitals across all 3 eras of public pneumococcal conjugate vaccine implementation in Canada. Results: The survival rate within our cohort of 180 recurrent invasive pneumococcal disease cases was 98.3%. A decrease of 26.4% in recurrent invasive pneumococcal disease due to vaccine serotypes was observed with pneumococcal vaccine introduction. There was also a 69.0% increase in the rate of vaccination in children with preexisting medical conditions compared with their healthy peers. Conclusion: The decrease in recurrent invasive pneumococcal disease due to vaccine-covered serotypes has been offset by an increase of non-vaccine serotypes in this sample of Canadian children.
Colorimetric Study on Polyamides Dyeing With Weld and Pomegranate Peel Natural Dyes

In this research, yellow color on nylon was produced by dyeing with weld (Reseda luteola) and pomegranate peel as natural dyes. The aluminum potassium sulphate salt was used as mordanting agent and four different methods of dyeing as non-mordanting, pre-mordanting, meta-mordanting, and after-mordanting were applied. The dyeing behavior of dyes was assessed by colorimetric evaluations and fastness properties. The spectrophotometric properties of dyed samples were also studied by Principal Component Analysis (PCA). Based on colorimetric evaluations, weld in comparison with pomegranate peel resulted in lighter and yellower colors. The rubbing fastness in all dyed samples was excellent, while samples dyed with pomegranate peel showed better washing fastness properties. Also, the best light fastness was obtained by the after-mordanting dyeing method. Overall, the best results of fastness properties were obtained by using after-mordanting method.
Cathepsin K activity controls cachexia‐induced muscle atrophy via the modulation of IRS1 ubiquitination

Cachexia is a complicated metabolic disorder that is characterize by progressive atrophy of skeletal muscle. Cathepsin K (CTSK) is a widely expressed cysteine protease that has garnered attention because of its enzymatic and non‐enzymatic functions in signalling in various pathological conditions. Here, we examined whether CTSK participates in cancer‐induced skeletal muscle loss and dysfunction, focusing on protein metabolic imbalance.
Complement evasion factor (CEF), a novel immune evasion factor of Streptococcus pyogenes

ABSTRACT Streptococcus pyogenes, a leading human pathogen, is responsible for a wide range of diseases, including skin and soft tissue infections and severe invasive diseases. S. pyogenes produces a large arsenal of virulence factors, including several immune evasion factors. We have identified an open reading frame (spy0136) in the S. pyogenes SF370 genome encoding a protein of unknown function. Using recombinant Spy0136 in a pull-down assay with human plasma and ELISA, we have identified four complement proteins (C1r, C1s, C3, and C5) as binding partners. Treatment of the complement proteins with PNGase F abrogated binding to C1s, C3, and C5, indicating glycan-dependent interactions. rSpy0136 inhibited complement-mediated hemolysis and interfered with all three complement pathways in a Wieslab complement assay. Furthermore, rSpy0136 inhibited deposition of the C3b opsonin and the membrane attack complex (MAC) on the surface of S. pyogenes. We therefore named the previously unknown protein ‘complement evasion factor’ (CEF). An S. pyogenes Δspy0136/cef deletion mutant showed decreased virulence in an in-vitro whole blood killing assay and a Galleria mellonella (wax moth) infection model. Furthermore, an L. lactis spy0136/cef gain-of-function mutant showed increased survival during growth in whole human blood. Analysis of serum samples from patients with invasive S. pyogenes revealed Spy0136/CEF sero-conversion indicating expression during disease. In summary, we have identified a novel S. pyogenes immune evasion factor that binds to several complement proteins to interfere with complement function. This is the first example of a S. pyogenes virulence factor binding to several different target proteins via glycan-dependent interactions.
Pulmonary function in patients with chronic stroke compared with a control group of healthy people matched by age and sex

ABSTRACT Background Effects of chronic stroke on pulmonary function are largely unknown. Aim To compare lung volumes in people with chronic stroke with a control group of healthy people matched by age and sex, as well as to investigate the relationship between the lung volumes and functional capacity. Methods A cross-sectional study involving people with chronic stroke. Cases were matched to a control group of healthy people. Lung function and the distance walked during the Six-Minute Walk Test (6MWD) were the main outcomes. Independent t-tests were used to compare pulmonary function between groups and the Pearson correlation coefficient was used to assess any relationship between lung volumes and the 6MWD in the stroke group. Results Sixty-six participants (24 males in each group; 56.5 ± 15.5 years) were included. People with stroke presented significantly lower lung volumes when compared to the control group. The median of forced vital capacity (FVC) was 79% and peak expiratory flow was 64% of the reference value. The 6MWD was found to be weakly correlated with inspiratory reserve volume (r = 0.39, p = .03) and peak inspiratory flow (r = 0.35, p = .05). Conclusions People with chronic stroke show decreased lung volumes when compared with healthy people and this likely impacts on their functional capacity.
Prevalence and Patterns of Refractive Errors in Children and Young Adults in an Urban Region in South India: the Hyderabad Eye Study

ABSTRACT Purpose To determine the prevalence of refractive error (RE) and associated risk factors for myopic refractive errors in children and young adults from the urban region of Hyderabad, South India. Methods Four thousand sixty-five (4,065) participants aged 6–22 years were enrolled and examined in this cross-sectional study conducted from October 2013 to January 2015. Participants were enrolled from a random sample of schools and universities in regions representative of urban Hyderabad. RE was determined using cycloplegic autorefraction. The association of demographic factors such as age, gender, and socio-economic category (SEC) (low/mid/high) with myopia was explored with logistic regression with robust standard error. Results Of the total participants, 2,259 were children aged 6–15 years and 1,806 were adolescents and young adults aged 16–22 years. Overall prevalence of myopia, high myopia (≤ −5.00D and ≤ −6.00 D), hyperopia, emmetropia, and astigmatism was 29.8% (95% CI: 26.0% to 33.6%, n = 1,216), 2.9% (95% CI: 1.9% to 3.9%, n = 120), 1.1% (95%CI: 0.7% to 1.5%, n = 46), 14.7% (95% CI: 12.4% to 17.0%, n = 599), 46.9% (95% CI: 43.7% to 50.1%, n = 1913) and 8.6% (95% CI: 7.4% to 9.9%, n = 352) respectively. A strong correlation existed between age and prevalence of myopia (R2 = 0.88, p < .001) and high myopia (R2 = 0.71, p < .001). Children from schools of low SEC (34.7%) had higher prevalence of myopia compared to the mid SEC (16.8%) (p = .043). Conclusion Myopia was the most prevalent refractive error and increased with age in this urban population. More myopia was observed in schools of low SEC.
A global perspective on embryological and fetal collections: Where to from here?

Human fetal and embryos collections (FECs) peaked in the late 19th century, an era before informed consent, and hence have unclear provenance. These collections are not only historical artifacts, but prized resources for education and research. This study aimed to determine, via a narrative review, the present location, status, and profile of reported human fetal and embryonic collections. Twenty‐seven articles that reported on collections appropriate to the study were selected from an initial search pool of 120 articles. The reported collections were in: Australia (n = 1), Germany (n = 6), Japan (n = 1), Spain (n = 1), and the United States (n = 5). The largest collection is reported to contain 45,000 prenatal remains and the smallest, three remains. The purpose of establishing majority of the collections was for education and research. Eight collections contain both embryos and fetuses, one collection contained embryos, exclusively. Another collection contained only fetuses and one neonatal cadaver. The provenance, where mentioned, specified gynecologists and obstetricians as the main source of remains (n = 5). Except for the Kyoto Collection, information regarding informed consent from the next‐of‐kin was lacking. This paper draws upon the three themes of purpose, provenance, and profile and highlights the need to establish agreed international guidelines for the most appropriate ethical and sustainable practice with respect to establishment, procurement of remains, access, and maintenance of these collections. Nine domains for these guidelines are recommended: consent, privacy, commercial gain, digital and emerging technologies, commemorations and memorials, destruction and disposal, dignity of donors, global database and collaboration, and sustainability.
Delayed pull‐through coloanal anastomosis without temporary stoma: an alternative to the standard manual side‐to‐end coloanal anastomosis with temporary stoma? A comparative study in 223 patients with low rectal cancer

After total mesorectal excision (TME) for low rectal cancer, current guideline recommendations for sphincter‐saving surgery are to perform a side‐to‐end manual coloanal anastomosis (CAA) (or with J‐pouch) with a temporary stoma. Our study aimed to evaluate if delayed pull‐through coloanal anastomosis (DCAA) without a temporary stoma could represent a safe alternative in low rectal cancer.
Social support, neurocognition, and posttraumatic stress disorder: Findings from the Canadian Longitudinal Study on Aging

ABSTRACT Objective Most research investigating neurocognitive changes in participants with PTSD has focused on young adults. Numerous studies have recognized the crucial role of social support in diminishing the likelihood of developing PTSD. The current study evaluates the cognitive performance of middle-aged and older adults with symptoms of PTSD, and examines if perceived social support can act as a cognitive reserve factor. Method The study was conducted using data from the Canadian Longitudinal Study on Aging, a nationwide study on health and aging. The current study included 1,096 participants in the PTSD group and 22,158 participants in the comparison group, all between the ages of 45 and 85. Participants completed the MOS (Medical Outcomes Study) Social Support Survey as well as neuropsychological tests in the domains of executive functioning, declarative memory, and prospective memory. Results The PTSD group had worse performance in the domains of executive functioning and prospective memory than the comparison group. Furthermore, when examining global cognitive impairments (impairment was defined as scoring 1.5 or more standard deviations below age and education adjusted comparison group), the PTSD group demonstrated greater impairment rates than the comparison group on two or more tests. Moderation analyses revealed that greater social support was associated with better executive functioning for the comparison group, although this was not found to be true for the PTSD group. Conclusion The PTSD group experienced greater cognitive deficits compared to the comparison group. Higher levels of perceived social support were associated with better performance on neurocognitive measures for the comparison group. However, social support did not appear to moderate this relationship for the PTSD group.
Impact of Social Support on the Physical Activity Behaviors of International College Students in the United States.

Research has suggested that international students' transition to the United States is often correlated with less physical activity after arriving in the U.S). One reason might be related to reduced social support when living in a foreign environment. The purpose of this cross-sectional study was to assess the impact of social support on international college students' physical activity behaviors. Participants (N = 318) from five public universities in one Midwest state completed an electronic survey assessing self-reported physical activity behaviors and perceived social support for exercise (SSE). Data analyses included multiple linear regression, multinomial logistic regression, and multiple logistic regression to test the study's hypotheses. Region of origin, academic level, and friends' SSE were all significant predictors of unhealthy physical activity behaviors. Specifically, friends' SSE was positively associated with higher total physical activity behaviors (F (12, 305) = 4.2, p < . 001, R 2 = . 142) and was a significant predictor of participants' physical activity levels. Although research suggests international students' transition to the United States can impart negative impacts on their physical activity behaviors, we found that greater levels of friends' SSE was associated with increased physical activity behaviors. As university administrators and wellness programs explore interventions promoting positive physical activity behaviors among international students, they should consider including elements that focus specifically on friendship social support to motivate physical activity behaviors.
Exploring the effectiveness of a fitness‐app prototype for home care service users in Austria and Italy

Abstract An infinite number of fitness apps are available on various app stores. However, hardly any of them are fitted to the needs and requirements of care‐dependent people. This paper investigates the effectiveness of a customised fitness‐app prototype for increasing physical activity in home care service users. Home care service users from Austria and Italy were randomly assigned to two groups. In total, 216 participants were involved in the field trial, 104 received a tablet with the fitness app and an activity tracker (treatment group), 112 did not (control group). Regularity of physical activity, frequency of fitness exercises and walking behaviour were self‐reported by participants at baseline, after 4 months and after 8 months. In addition, the frequency of using the prototype was assessed based on the fitness app's logged usage data. We estimated multilevel mixed‐effects ordered logistic models to examine the effects of the intervention. After 4 months, the intervention increased the home care users’ probability of agreeing strongly with being physically active on a regular basis by 28 percentage points (p < 0.001; 95% CI: 0.20, 0.36) and their probability of reporting to exercise more than once a week by 45 percentage points (p < 0.001; 95% CI: 0.32, 0.57). Walking behaviour was not affected on group‐level but improved for frequent users of the activity tracker. Frequent and regular users of the fitness app benefited most and effects persisted until the end of the 8 months controlled trial. Tailoring a fitness‐app prototype to the needs of care‐dependent people has the potential to support people with functional limitations to engage in a more active lifestyle. Future research is encouraged to seek further insights into how new technologies can support physical activities in people with long‐term care needs.
Acquired Prosopagnosia with Structurally Intact and Functional Fusiform Face Area and with Face Identity-Specific Configuration Processing Deficits.

Prosopagnosia or loss of face perception and recognition is still poorly understood and rare single cases of acquired prosopagnosia can provide a unique window on the behavioural and brain basis of normal face perception. The present study of a new case of acquired prosopagnosia with bilateral occipito-temporal lesions but a structurally intact FFA and OFA investigated whether the lesion overlapped with the face network and whether the structurally intact FFA showed a face selective response. We also investigated the behavioral correlates of the neural findings and assessed configural processing in the context of facial and non-facial identity recognition, expression recognition and memory, also focusing on the face-selectivity of each specific deficit. The findings reveal a face-selective response in the FFA, despite lesions in the face perception network. At the behavioural level, the results showed impaired configural processing for facial identity, but not for other stimulus categories and not for facial expression recognition. These findings challenge a critical role of the FFA for face identity processing and support a domain-specific account of configural processing.
Online breast-feeding support groups as a community asset in Lebanon after Beirut explosion

Abstract Objective: Breast-feeding rates are unsatisfactory in Lebanon. Social media groups could play an important role in promoting breast-feeding in normal conditions and post crisis. The aim of this study is to identify breast-feeding challenges, facilitators and assets and to describe how community assets via social media could build community resilience to pandemic’s and disaster’s effects. Design: A two-phase qualitative content analysis was performed on posts and comments collected from a Facebook breast-feeding support group. Data were categorised into themes, categories and subcategories. Setting: Posts and comments retrieved from a Facebook breast-feeding support group in Lebanon during the month of August 2020. Participants: Group members: mothers who breastfed, breast-feeding mothers and group admins that are lactation consultants. Results: In phase one, breast-feeding ‘Challenges’ identified were lack of support from peers and family, lack of supportive policies, lack of knowledge and maternal stress related to political instability, COVID-19 and economic crisis. ‘Assets and facilitators’ included community support and donations. In phase two, analysis revealed how assets were being used on social media platform to build community resilience post crisis, through access to social support in challenging times, community engagement, material resources and transformative potential. Conclusion: Challenges faced during breast-feeding were diminished due to the support and assets received on a Facebook breast-feeding support group, and social media has been shown to be an important community asset implicated in empowering women to breastfeed and to build community resilience in moments of crisis.
Probiotic properties of yeasts in traditional fermented foods and beverages

The interest in potentiality and functionality of probiotic yeasts from fermented foods has increased drastically over the years. In many fermented foods and beverages, lactic acid bacteria and yeasts exist synergistically by stimulating their growth and survival. Probiotic strains of lactic acid bacteria are more widely studied than potential probiotic yeasts. Saccharomyces cerevisiae variety boulardii is the only commercialized probiotic yeast, which are extensively studied. This review article provides information on the presence of potential probiotic yeasts in some traditional fermented foods and beverages.
Loss of STING expression is prognostic in non–small cell lung cancer

Stimulator of interferon (IFN) genes (STING) is a protein that promotes type I IFN production essential for T‐cell activation. In this study, we aim to characterize STING expression comprehensively using The Cancer Genome Atlas (TCGA) database, cell lines, and patient tumor samples stained with immunohistochemistry.
An accurate locally active memristor model for S-type negative differential resistance in NbOx

A number of important commercial applications would benefit from the introduction of easily manufactured devices that exhibit current-controlled, or “S-type,” negative differential resistance (NDR). A leading example is emerging non-volatile memory based on crossbar array architectures. Due to the inherently linear current vs. voltage characteristics of candidate non-volatile memristor memory elements, individual memory cells in these crossbar arrays can be addressed only if a highly non-linear circuit element, termed a “selector,” is incorporated in the cell. Selectors based on a layer of niobium oxide sandwiched between two electrodes have been investigated by a number of groups because the NDR they exhibit provides a promisingly large non-linearity. We have developed a highly accurate compact dynamical model for their electrical conduction that shows that the NDR in these devices results from a thermal feedback mechanism. A series of electrothermal measurements and numerical simulations corroborate this model. These results reveal that the leakage currents can be minimized by thermally isolating the selector or by incorporating materials with larger activation energies for electron motion.
Hydraulic vulnerability segmentation in compound-leaved trees: evidence from an embolism visualization technique.

The hydraulic vulnerability segmentation (HVS) hypothesis implies the existence of differences in embolism resistance between plant organs along the xylem pathway and has been suggested as an adaptation allowing the differential preservation of more resource-rich tissues during drought stress. Compound leaves in trees are considered a low-cost means of increasing leaf area and may thus be expected to show evidence of strong HVS, given the tendency of compound-leaved tree species to shed their leaf units during drought. However, the existence and role of HVS in compound-leaved tree species during drought remain uncertain. We used an optical visualization technique to estimate embolism occurrence in stems, petioles, and leaflets of shoots in two compound-leaved tree species, Manchurian ash (Fraxinus mandshurica) and Manchurian walnut (Juglans mandshurica). We found higher (less negative) water potentials corresponding to 50% loss of conductivity (P50) in leaflets and petioles than in stems in both species. Overall, we observed a consistent pattern of stem > petiole > leaflet in terms of xylem resistance to embolism and hydraulic safety margins (i.e., the difference between mid-day water potential and P50). The coordinated variation in embolism vulnerability between organs suggests that during drought conditions, trees benefit from early embolism and subsequent shedding of more expendable organs such as leaflets and petioles, as this provides a degree of protection to the integrity of the hydraulic system of the more carbon costly stems. Our results highlight the importance of HVS as an adaptive mechanism of compound-leaved trees to withstand drought stress.
