Clinical presentation, disease course, and outcome of COVID-19 in hospitalized patients with and without pre-existing cardiac disease: a cohort study across 18 countries

AIMS

Patients with cardiac disease are considered high risk for poor outcomes following hospitalization with COVID-19. The primary aim of this study was to evaluate heterogeneity in associations between various heart disease subtypes and in-hospital mortality.

METHODS AND RESULTS

We used data from the CAPACITY-COVID registry and LEOSS study. Multivariable Poisson regression models were fitted to assess the association between different types of pre-existing heart disease and in-hospital mortality. A total of 16 511 patients with COVID-19 were included (21.1% aged 66-75 years; 40.2% female) and 31.5% had a history of heart disease. Patients with heart disease were older, predominantly male, and often had other comorbid conditions when compared with those without. Mortality was higher in patients with cardiac disease (29.7%; n = 1545 vs. 15.9%; n = 1797). However, following multivariable adjustment, this difference was not significant [adjusted risk ratio (aRR) 1.08, 95% confidence interval (CI) 1.02-1.15; P = 0.12 (corrected for multiple testing)]. Associations with in-hospital mortality by heart disease subtypes differed considerably, with the strongest association for heart failure (aRR 1.19, 95% CI 1.10-1.30; P < 0.018) particularly for severe (New York Heart Association class III/IV) heart failure (aRR 1.41, 95% CI 1.20-1.64; P < 0.018). None of the other heart disease subtypes, including ischaemic heart disease, remained significant after multivariable adjustment. Serious cardiac complications were diagnosed in <1% of patients.

CONCLUSION

Considerable heterogeneity exists in the strength of association between heart disease subtypes and in-hospital mortality. Of all patients with heart disease, those with heart failure are at greatest risk of death when hospitalized with COVID-19. Serious cardiac complications are rare during hospitalization.

Love and peace across generations: Biobehavioral systems and global partnerships

Children's environments - especially relationships with caregivers - sculpt not only developing brains but also multiple bio-behavioral systems that influence long-term cognitive and socioemotional outcomes, including the ability to empathize with others and interact in prosocial and peaceful ways. This speaks to the importance of investing resources in effective and timely programs that work to enhance early childhood development (ECD) and, by extension, reach communities at-scale. Given the limited resources currently devoted to ECD services, and the devastating impact of COVID-19 on children and communities, there is a clear need to spur government leaders and policymakers to further invest in ECD and related issues including gender and racial equity. This essay offers concrete examples of scholarly paradigms and leadership efforts that focus on child development to build a peaceful, equitable, just, and sustainable world. As scholars and practitioners, we need to continue to design, implement, assess, and revise high-quality child development programs that generate much-needed evidence for policy and programmatic changes. We must also invest in global partnerships to foster the next generation of scholars, practitioners, and advocates dedicated to advance our understanding of the bio-behavioral systems that underlie love, sociality, and peace across generations. Especially where supported by structural interventions, ECD programs can help create more peaceful, just, and socially equitable societies.

Prevalence of atherosclerosis risk factors in Egyptian patients with acute coronary syndromes; final data of the nationwide cross-sectional CardioRisk project

Background

Little are known about the prevalence of atherosclerosis risk factors in Egyptian patients with acute coronary syndromes (ACS). Objective: To describe the prevalence of these risk factors with focus on gender-specific data and patients with premature presentation.

Methods

From November 2015 to August 2018, data were collected from 3224 patients with ACS in 30 coronary care centers covering 11 governorates across Egypt, with focus premature ACS.

Results

The vast majority were males (74%) and the most prevalent age group was (56–65 years) representing 37% of whole study population. Among female patients, 92% were post-menopausal. The prevalence of premature ACS was 51%. Forty five percent of total males and 69.6% of total females with ACS had premature presentation (P&lt;0.001). Abdominal obesity was the most prevalent risk factor (66%). Nearly half of the entire study patients were current smokers (48%). We showed a high prevalence of documented dyslipidemia (48%) as well. Early invasive management strategy was employed in 65% of patients with no significant gender disparity noticed. Vascular access for coronary angiography was most commonly femoral (80% of time). Emergent percutaneous coronary intervention (PCI) was attempted in 53% of patients. Thrombolytic therapy (using Streptokinase) was used in 24% of included participants.

Conclusion

Among Egyptian patients with ACS, premature presentation is common with greater male preponderance. Abdominal obesity is the most prevalent risk factor followed by hypertension. Most traditional risk factors (apart from smoking) were more prevalent in women than men.

Effects of the Mother-Child Education Program on Parenting Stress and Disciplinary Practices Among Refugee and Other Marginalized Communities in Lebanon: A Pilot Randomized Controlled Trial

OBJECTIVE

Few randomized controlled trials (RCTs) have explored the implementation and impact of early childhood parenting education programs in very fragile contexts and humanitarian settings. We tested the effects of a group-based intervention, the Mother-Child Education Program (MOCEP), on parenting stress and practices among two refugee communities and one other marginalized community in Beirut, Lebanon.

METHOD

A pilot wait-list RCT was conducted to assess the program's impact on maternal, child (average age: 4 years), and dyadic outcomes. A total of 106 mother-child dyads were randomly assigned to either the intervention group (n = 53) or the wait-list control group (n = 53). Analysis was conducted by modified intention-to-treat and supplemental analyses through multiple imputation of missing post-intervention data.

RESULTS

Forty families (38%) withdrew early from the study. After completing the program, mothers in the intervention group showed a reduction in their harsh parenting practices, as indexed by the Disciplinary Style Questionnaire (Cohen's d = -0.76, 95% CI = -1.24, -0.27) and in their level of parenting stress, as indexed by the Parenting Stress Index-Short Form (PSI-SF; Cohen's d = -0.90, 95% CI = -1.39, -0.40). Exploratory but underpowered analyses of dyadic interactions revealed reductions in the PSI were associated with a reduction in harsh parenting after the intervention. However, we did not detect any positive impact on behavioral or emotional outcomes among the children.

CONCLUSION

Our analyses suggest that MOCEP had a positive impact on disciplinary practices and parenting stress in a context of high fragility, but that broader effects on maternal and child outcomes may be dependent on program attendance and the availability of other services. We discuss implications of this pilot study for practice and research of a largely unexplored area of program evaluation.

Maternal perceptions of father involvement among refugee and disadvantaged families in Beirut, Lebanon

The role of fathers in (co-)parenting their children among refugee and disadvantaged families in low and middle-income countries (LMICs) remains poorly understood. This study sought to examine the associations among mothers' perceptions of their husband's involvement (hereafter referred to as paternal involvement), and her perceptions of her own well-being and a number of other variables, as well as observed mother-child interactions in families living in refugee and disadvantaged communities in Beirut, Lebanon. We analyzed baseline data from 104 mother-child dyads (mean age of children = 4.34 years; range = 2.05 to 7.93 years of age) who participated in a randomized controlled trial aimed at evaluating the impact of the Mother-Child Education Program in Beirut. In addition to the mother's perception of paternal involvement and the videotaped mother-child interactions, data were collected concerning the mother's well-being and her level of social support, as well as her level of stress as a parent and the way her children were disciplined in the family. Mother-child pairs were videotaped while completing a puzzle together and dyadic interactions were coded. Path analysis showed that paternal involvement was significantly associated with a higher level of maternal well-being and lower distress levels. In addition, higher levels of maternal distress were associated with higher levels of harsh discipline and parenting stress. Correlation analysis showed that higher perceptions of paternal involvement were associated with more positive affect displayed by the child, more positive regard for the child, and better mother-child synchrony during the dyadic interactions. Limitations include the cross-sectional design and the modest sample size, which hinder causal inferences and generalizability of the findings. These preliminary findings suggest that higher levels of paternal involvement may have an impact on markers of maternal mental health and positive mother-child interactions in families living in disadvantaged communities or humanitarian settings. Paternal involvement should be considered when designing and implementing parenting programs in LMICs.

Global Citizenship and the Role of the United Nations: The Promise of the Early Childhood Peace Consortium

Today millions of children are trapped in situations of war, conflict, violence and displacement. Science shows that violence has a detrimental effect on the development of young children. It, also, heralds in a new era, with opportunities to contribute to sustaining peace and prevention of violence, through investment in early childhood development. The commentary argues that we have every opportunity to make a transformative shift and raise the voice of science to join the voice of "we the peoples..." The voice of "we the peoples" to stop war and violence in the world, promoting "a Culture of Peace," adhering to the principles of freedom, justice, tolerance, and advancing the concept of Global Citizenship, is clear. It is amplified by the historic adoption of the "2030 Agenda for Sustainable Development" and the "Sustaining Peace Resolutions," calling on every member of society to participate in peacebuilding and development efforts. The promise of the Early Childhood Peace Consortium (ECPC) is to join forces by creating a global movement to build more peaceful homes and societies, drawing on the experience of early childhood development and the transformative power of children and families.

Effects of chitin and its derivatives on human cancer cells lines

The present study is focused on the effect of chitin derivatives against human cancer cell lines RD and Hep2. As an outcome from this research, chitin was cytotoxic at IC50 = 400 μg/ml and 200 μg/ml against Hep2 cells and RD cells lines, respectively. Irradiated chitin had an IC50 value of 450 μg/ml for Hep2 and an IC50 of 200 μg/ml for RD. The lowest IC50 is attributed to chitosan, 300 μg/ml in Hep2 and 190 μg/ml in RD.

A comparison of sagittal short T1 inversion recovery and T2-weighted FSE sequences for detection of multiple sclerosis spinal cord lesions

PURPOSE

Multiple sclerosis (MS) is the most common disabling CNS disease of young adults. MRI is routinely used for the detection of MS plaques in the brain and spinal cord. A significant portion of patients with MS demonstrates spinal cord lesions at the time of initial workup, and these lesions are an important part of the McDonald criteria for diagnosis. However, whereas brain imaging sequences are now fairly standardized, there continues to be debate about the optimal sequences for imaging the spinal cord. The short T1 inversion recovery (STIR) sequence has been shown in the current literature to improve lesion detection with its additive T1/T2 weighting, but current spinal cord imaging protocols from the Consortium on MS Center Consensus Guidelines do not include the STIR sequence. We demonstrate that not only do STIR sequences improve lesion detection when compared directly with conventional T2-weighted sequences, but that they also significantly improve lesion conspicuity, facilitating earlier positive diagnosis and management.

MATERIALS AND METHODS

Dedicated MR spinal cord imaging of twenty-nine sequential patients with clinically confirmed multiple sclerosis was retrospectively analyzed by two independent neuroradiologists in a novel study design. Sagittal T2-weighted and STIR sequence images from the same study for each patient were examined for MS plaques using a double-blinded review of individual images 'separated in time and space', such that STIR and T2 image pairs were never analyzed simultaneously. Number of lesions and lesion conspicuity for each lesion, using a subjective scale (1-5), were tallied for each sequence. Averages for each observer were compared using a paired t-test analysis for statistical significance, and assessment of inter-rater agreement was assessed using Cohen's kappa index.

RESULTS

Significantly, more MS lesions were detected on STIR than on T2-weighted sequences for both observers (P = 0.001 and P = 0.005). In seven patients, the conventional T2 sequence detected no lesions at all, whereas STIR sequences showed significant cord involvement. Lesion conspicuity was also significantly better on STIR for both observers (P < 0.0005). This improved conspicuity leads to more uniform lesion detection. On the conventional T2-weighted sequence, there was a statistically significant difference in the number of lesions detected between the two observers (P = 0.003), but there was no statistically significant difference on STIR (P = 0.43). The kappa index showed greater interobserver agreement in both lesion count and lesion conspicuity on the STIR sequence as compared with T2.

CONCLUSIONS

Short T1 inversion recovery sequence imaging not only significantly improves detection of MS lesions within the spinal cord, but also provides better contrast and conspicuity of visible lesions, creating a more confident diagnostic measure of MS extent and progression. Short T1 inversion recovery sequences of the spinal cord should be routinely obtained during initial and routine follow-up of MS.

Micropapillary transitional cell carcinoma of the urinary bladder: report of two cases

Micropapillary carcinoma is an uncommon variant of urothelial carcinoma with apparent high metastatic potential. The reported cases in the literature were associated with high grade and stage of disease at presentation and a poor prognosis. Micropapillary carcinoma is considered a tumor with an aggressive behavior, even though the morphology may be deceptive. The presence of a micropapillary carcinoma component in bladder biopsies should alert the urologists to the potential of higher stage disease and deep biopsies should be obtained. Two cases of micropapillary carcinoma of the urinary bladder were presented. A 71-year-old woman and a 68-year-old man presented with urinary symptoms. Cystoscopy revealed a papillary tumor on the bladder wall in both cases. Pathologic examination of transurethral resection specimen showed an invasive micropapillary carcinoma; small solid nests lying in small clear spaces that were not stained with antibody CD34. Thus, the lacunar histological pattern did not appear to represent invasion of vascular spaces. Only one case showed an association with urothelial carcinoma. No case showed muscle invasion. No recurrence or metastasis were observed after the initial diagnosis in the two cases.
