Abstract
Hypertrophic cardiomyopathy is the most common genetic cardiac disorder and is defined by the presence of left ventricular (LV) hypertrophy in the absence of a condition capable of producing such a magnitude of hypertrophy. Over the past decade, guidelines on the screening, diagnostic, and management protocols of pediatric primary (i.e., sarcomeric) HCM have undergone significant revisions. Important revisions include changes to the appropriate screening age, the role of cardiac MRI (CMR) in HCM diagnosis, and the introduction of individualized pediatric SCD risk assessment models like HCM Risk-kids and PRIMaCY. This review explores open uncertainties in pediatric HCM that merit further attention, such as the divergent American and European recommendations on CMR use in HCM screening and diagnosis, the need for incorporating key genetic and imaging parameters into HCM-Risk Kids and PRIMaCY, the best method of quantifying myocardial fibrosis and its prognostic utility in SCD prediction for pediatric HCM, devising appropriate genotype- and phenotype-based exercise recommendations, and use of heart failure medications that can reverse cardiac remodeling in pediatric HCM.

Abstract
BACKGROUND Data on race-related differences in the clinical outcomes of Takotsubo syndrome are limited, particularly for Black patients. This study aimed to assess whether race and sex may have an additional impact on the inpatient mortality of patients with Takotsubo syndrome. METHODS A total of 4,628 patients from the United States' National Inpatient Sample from 2012 to 2016 were identified; propensity score analysis revealed a similar propensity score between Black patients (n = 2,314) and White patients (n = 2,314), which was used to balance observed covariates. Sex and age distributions were identical between the 2 groups. The groups were also similar in baseline characteristics, including cardiovascular risk factors. White patients were compared with Black patients on in-hospital outcomes and inpatient mortality. A logistic regression analysis was conducted to measure the difference in mortality based on race and sex. RESULTS Compared with White patients, Black patients had a higher percentage of in-hospital complications, including cerebrovascular accidents (4.9% vs 2.5%, P ≤ .01), acute kidney injury (25% vs 19%, P ≤ .01); longer lengths of stay (8 vs 7 days, P ≤ .01); and higher inpatient mortality (6.1% vs 4.5%, P < .01). When analysis was conducted with race and sex combined, inpatient mortality was higher among Black men than among White women (odds ratio, 2.7 [95% CI, 1.80-3.95]; P ≤ .01). CONCLUSION This study showed that Black patients with Takotsubo syndrome have higher in-hospital complications and inpatient mortality rates. When race and sex were combined, inpatient mortality was significantly higher among Black men than among either White men and women or Black women.

Abstract
Age and sex differences in Takotsubo syndrome (TTS) are still a matter of debate. The present study aimed to evaluate the difference in cardiovascular (CV) risk factors, CV disease, in-hospital complications, and death within different sex-age groups. Using the National Inpatient Sample database between 2012 and 2016, 32,474 patients older than 18 years of age hospitalized with the primary diagnosis of TTS were identified. A total of 32,474 patients were enrolled; 27,611 (85.04%) were female. CV risk factors were higher in females, while CV diseases and in-hospital complications were significantly higher in males. The mortality in males was twice as high as that of female patients (9.83% versus 4.58%, p<0.01), and in the logistic regression model after adjustment for confounders, the odds ratio (OR) was 1.79, the confidence interval was 1.60-2.02, and p<0.01. After dividing the group based on age, in-hospital complications were inversely related to age in both sexes, and the length of in-hospital stay was double in the youngest group compared to the oldest one. Mortality increased progressively with age in both groups but was constantly higher in males for each age group. Multiple logistic regression analysis for mortality was performed for the two sexes separately and for the three age groups, considering the youngest one as the reference group. In females, the OR was 1.59 and 2.88, respectively, for groups 2 and 3; for males, the OR was 1.92 and 3.15, all of them statistically significant (p<0.01). In-hospital complications were more common in younger patients with TTS, particularly in males. Mortality was positively correlated with age for both sexes, but mortality was higher in males compared to females in all age groups.

Abstract
Human epidermal growth factor receptor-positive breast cancer is an aggressive cancer which represents approximately a quarter of all breast cancers worldwide. Recent advances have led to the development of targeted therapies, such as trastuzumab (H), which have significantly improved prognosis. Such therapies are currently used alongside other chemotherapeutic agents, such as paclitaxel (P) and gemcitabine (G). The most common side effects of PGH combination therapy include thrombocytopenia and anemias. However, there have been no previous reports of myositis resulting from this combination. We report the case of a 54-year-old metastatic breast cancer patient on PGH therapy who developed muscle weakness. The patient was initially treated with trastuzumab, pertuzumab, and paclitaxel. However, pertuzumab was changed to gemcitabine due to severe diarrhea. After the fourth cycle of PGH, the patient presented with muscle weakness and creatine kinase levels of up to 6755 U/L. Magnetic resonance imaging of the femur and pelvis revealed diffuse bilateral myositis, suggesting a diagnosis of gemcitabine-induced myositis. The patient was placed on intravenous fluids and corticosteroids, which resolved her condition. To our knowledge, this is the first report of gemcitabine-induced myositis in a breast cancer patient. Further studies are needed to determine the underlying mechanisms of gemcitabine-induced myositis and develop preventative measures.

Abstract
Patients suffering from end-stage heart failure tend to have high mortality rates. With growing numbers of patients progressing into severe heart failure, the shortage of available donors is a growing concern, with less than 10% of patients undergoing cardiac transplantation (CTx). Fortunately, the use of left ventricular assist devices (LVADs), a variant of mechanical circulatory support has been on the rise in recent years. The expansion of LVADs has led them to be incorporated into a variety of clinical settings, based on the goals of therapy for patients ailing from heart failure. However, with an increase in the use of LVADs, there are a host of complications that arise with it. One such complication is the development and progression of aortic regurgitation (AR) which is noted to adversely influence patient outcomes and compromise pump benefits leading to increased morbidity and mortality. The underlying mechanisms are likely multifactorial and involve the aortic root-aortic valve (AV) complex, as well as the LVAD device, patient, and other factors, all of them alter the physiological mechanics of the heart resulting in AV dysfunction. Thus, it is imperative to screen patients before LVAD implantation for AR, as moderate or greater AR requires a concurrent intervention at the time of LVADs implantation. No current strict guidelines were identified in the literature search on how to actively manage and limit the development and/or progression of AR, due to the limited information. However, some recommendations include medical management by targeting fluid overload and arterial blood pressure, along with adjusting the settings of the LVADs device itself. Surgical interventions are to be considered depending on patient factors, goals of care, and the underlying pathology. These interventions include the closure of the AV, replacement of the valve, and percutaneous approach via percutaneous occluding device or transcatheter aortic valve implantation. In the present review, we describe the interaction between AV and LVAD placement, in terms of patient management and prognosis. Also it is provided a comprehensive echocardiographic strategy for the precise assessment of AV regurgitation severity.

Abstract
Nasal gliomas are congenital masses of dysplastic neuroglial and fibrovascular tissue. However, other congenital nasal masses, including encephaloceles, hemangiomas, and dermoid cysts make clinical diagnosis difficult. Radiological examination is imperative to accurate diagnosis of nasal gliomas. We hereby present the diagnostic imaging features of these lesions, which necessitate inclusion into the differential diagnosis of a congenital nasal mass.

Abstract
All currently approved COVID-19 vaccines utilize the spike protein as their immunogen. SARS-CoV-2 variants of concern (VOCs) contain mutations in the spike protein, enabling them to escape infection- and vaccination-induced immune responses to cause reinfection. New vaccines are hence being researched intensively. Studying SARS-CoV-2 epitopes is essential for vaccine design, as identifying targets of broadly neutralizing antibody responses and immunodominant T-cell epitopes reveal candidates for inclusion in next-generation COVID-19 vaccines. We summarize the major studies which have reported on SARS-CoV-2 antibody and T-cell epitopes thus far. These results suggest that a future of pan-coronavirus vaccines, which not only protect against SARS-CoV-2 but numerous other coronaviruses, may be possible. The T-cell epitopes of SARS-CoV-2 have gotten less attention than neutralizing antibody epitopes but may provide new strategies to control SARS-CoV-2 infection. T-cells target many SARS-CoV-2 antigens other than spike, recognizing numerous epitopes within these antigens, thereby limiting the chance of immune escape by VOCs that mainly possess spike protein mutations. Therefore, augmenting vaccination-induced T-cell responses against SARS-CoV-2 may provide adequate protection despite broad antibody escape by VOCs.

Abstract
After heart failure, infectious endocarditis is the second leading cause of death in patients with prosthetic valves. Aortic pseudoaneurysms are a serious complication of infective endocarditis in mechanical or bioprosthetic aortic prostheses. Diagnostic and management challenges are posed by aortic pseudoaneurysms. In these cases, a multi-modality imaging approach with a heart team is recommended. We described two cases of aortic pseudoaneurysms that developed as a result of infective endocarditis. The first case involved a TAVI patient who developed infective endocarditis as a result of diabetic foot complications. Because traditional echocardiography and computed tomography failed to show the anatomy of the lesion, we used 3D printing to show the anatomy, extension of the pseudoaneurysm, and proximity to the right coronary artery. The second case involved a patient who underwent Bentall's surgery with an aortic root and mechanical aortic valve and later developed infective endocarditis complicated by pseudoaneurysms. In this case, 3D printing was used for preoperative surgical planning.

Abstract
A 17-year-old female presented to our hospital complaining of bloody diarrhea 4-6 times per day for the past month. She was a known case of inflammatory bowel disease noncompliant to her medications. Abdominal computed tomography revealed an unusually dilated mass in the retroperitoneum at L2 vertebral level connecting the lumbar and left renal veins. The renal artery was visualized separately, and a diagnosis of communicating vein varicosity was made. This lesion can be misleading on imaging, hence our aim to disseminate our findings to practicing radiologists. The differential diagnosis of these lesions include retroperitoneal lymphadenopathy, renal artery aneurysms, and testicular cancers causing retroperitoneal lymphadenopathy. To our knowledge, this is the first case to be reported in association with inflammatory bowel disease, perhaps providing a novel insight into the pathogenesis of this lesion that has not been considered in the contemporary literature.

Introduction
Rheumatic mitral valve stenosis (MS) causes progressive left atrial (LA) fibrosis and functional impairment, pulmonary artery systolic hypertension and right ventricular (RV) dysfunction.
Purpose
The aim of the study was the evaluate the different characteristics between high gradients (HG) and low gradient (LG) MS and, within the LG group those with high (LG-HF) or low flow (LG-LF). Moreover, we wanted to evaluate if there was any difference in overall complications and atrial fibrillation (AF) incidence.
Methods
A total of 147 patients with isolated severe MS were retrospectively enrolled from the institutional echo database. Echocardiograms were read offline and clinical information were obtained from patients` records. Patients were divided into a group with HG (31 patients, mean MS gradient > 10 mmHg) and LG (116 patients, mean MS gradient ≤ 10 mmHg). The group of LG was then divided in low flow (Stroke volume index (SVi) ≤ 35 ml/m2, LF-LG: 68 patients) and in high flow (SVi > 35 ml/m2, HF-LG: 48 patients).
Results
The HG group was younger, although the difference did not reach statistical significance, higher percent of males (45% M vs 22% F, p = 0.02), higher heart rate (HR), left atrial volume, higher tricuspid regurgitation velocity (TVR) and derived pulmonary artery systolic pressure (PASP), RV fractional area changes (RV FAC) but similar RV longitudinal contraction. Moreover, the HG group had more severe MS calculated according to PHT. The group of LG was divided according to SVi: LF-LG group compare to HG-MS had higher percent of females (45% F vs 13% M, p < 0.001), similar AF (43% vs 32%, p = ns) and pre surgical complications (19% vs 16%, p = ns). LF-LG group had smaller LA systolic volume (117 ± 51 51 ml vs 148.6 ± 38 ml, p < 0.0001), lower LV-S` (5.3 ± 1.4 vs 6 ± 1.6 cm/s, p = 0.004), lower TRV (2.47 ± 0.5 vs 3.24 ± 0.7 m/s, p < 0.0001), higher TAPSE/PASP (0.64 ± 0.3 vs 0.45 ± 0.29, p < 0.001), lower RV S` (9.79 ± 2.01m/s vs 11.25 ± 3.1 m/s, p = 0.01), higher RVFAC (38.5 ± 9.6% vs 30.9 ± 9.2%, p = 0.0005). The group of LG-LF had also less severe MS (1.3 ± 0.6 cm2 vs 1.15 ± 0.3 cm2, p < 0.01).
Conclusion
Patients with HG MS were those with worst left ventricular involvement, higher PASP and lower RV function. The LF-LG MS were older, and more females were included and even though they had smaller LA, lower values of PASP they had significantly higher percent of AF and similar pre surgical complications. It could be speculated that LF-LG severe MS patients could be a different phenotype of the disease.

Background
Stuck valve is a very rare and severe complication that occurs in mechanical valve replacement patients with ineffective anticoagulation. However, with COVID-19 restriction measures, it became challenging to regularly assess INR to make sure it falls within the target therapeutic range to prevent this complication.
Purpose
We wanted to explore how did the COVID-19 pandemic restrictions impacted mechanical valve replacement patients on chronic anticoagulation and the long-term consequences of limiting their access to health service.
Methods
We present a series of 10 patients on warfarin anticoagulation therapy who either underwent transthoracic echocardiography for a suspected stuck valve or were seen at the outpatient valve clinic with the residual consequences of a stuck valve during the COVID-19 restriction measures in our institute.
Results
Eight patients were female, two of whom were pregnant at the first trimester and eventually went on to receive an abortion; six patients received urgent valve replacement cardiac surgery; four patients were managed medically e.g. with heparin; none had thrombolytic therapy. Stuck prosthetic valves incident has increased significantly during this period, particularly those in the mitral position for which urgent replacement and prolonged hospitalization including intensive care admission, with high in-hospital mortality rates and high costs were necessary. Mean hospital admission time was 27.5 ± 18.5 days. The cost of treatment, as average estimated reimbursement, was 11,000 USD for medical admission only, and 43,200 USD when surgery was required, up to 64,000 USD when ECMO was part of patient management.
Conclusion
Despite governments’ efforts to implement telemedicine and virtual clinics, COVID-19 restrictions and health-messaging affected the routine follow-up of non-COVID-19 patients. We report dramatic consequences to this drastic change in healthcare: clinical complications, lost lives and inflated healthcare costs in patients with a prosthetic valve. We believe that non-COVID-19 patients have paid, and will continue to pay in the future, a price that is much greater than those patients who have suffered from COVID-19. Active engagement of patients should be implemented in a time of emergencies, and further studies should address the efficacy and cost-effectiveness of public policies aimed to decrease the burden of avoidable complications and missed diagnoses.

Abstract
Hypertrophic cardiomyopathy (HCM) is a group of heterogeneous disorders that are most commonly passed on in a heritable manner. It is a relatively rare disease around the globe, but due to increased rates of consanguinity within the Kingdom of Saudi Arabia, we speculate a high incidence of undiagnosed cases. The aim of this paper is to elucidate a systematic approach in dealing with HCM patients and since HCM has variable presentation, we have summarized differentials for diagnosis and how different subtypes and genes can have an impact on the clinical picture, management and prognosis. Moreover, we propose a referral multi-disciplinary team HCM-Family Unit in Saudi Arabia and an integrated role in a network between King Faisal Hospital and Inherited and Rare Cardiovascular Disease Unit-Monaldi Hospital, Italy (among the 24 excellence centers of the European Reference Network (ERN) GUARD-Heart).

Abstract
Huntington Disease (HD) is an inherited movement disorder caused by expanded CAG repeats in the Huntingtin gene. We have used single nucleus RNASeq (snRNASeq) to uncover cellular phenotypes that change in the disease, investigating single cell gene expression in cingulate cortex of patients with HD and comparing the gene expression to that of patients with no neurological disease. In this study, we focused on astrocytes, although we found significant gene expression differences in neurons, oligodendrocytes, and microglia as well. In particular, the gene expression profiles of astrocytes in HD showed multiple signatures, varying in phenotype from cells that had markedly upregulated metallothionein and heat shock genes, but had not completely lost the expression of genes associated with normal protoplasmic astrocytes, to astrocytes that had substantially upregulated glial fibrillary acidic protein (GFAP) and had lost expression of many normal protoplasmic astrocyte genes as well as metallothionein genes. When compared to astrocytes in control samples, astrocyte signatures in HD also showed downregulated expression of a number of genes, including several associated with protoplasmic astrocyte function and lipid synthesis. Thus, HD astrocytes appeared in variable transcriptional phenotypes, and could be divided into several different “states”, defined by patterns of gene expression. Ultimately, this study begins to fill the knowledge gap of single cell gene expression in HD and provide a more detailed understanding of the variation in changes in gene expression during astrocyte “reactions” to the disease.

Abstract
Coarctation of aorta (CoA) usually leads to elevation of blood pressure above the site of obstruction and this elevated blood pressure probably gets transferred and is reflected in the retinal arterioles producing certain signs of hypertensive retinopathy. Fundus examination helps in differentiating hypertension due to CoA from other causes of juvenile hypertension, as corkscrewing of retinal arterioles is seen only in CoA but not in other conditions. A 16 year hypertensive male who was on antihypertensive treatment presented for routine checkup. On examination his visual acuity was 6/6 in both eyes. Funduscopy of both eyes revealed a normal optic disc with generalised narrowing of arterioles and broadened light reflex. The arterioles showed corkscrew tortuosity (U shaped arterioles). Based on the fundus findings, CoA was suspected and the patient was referred for cardiac evaluation. Echocardiogram revealed post ductal CoA. In juvenile hypertension, careful examination of the fundus can provide a clue to the systemic diagnosis and this case highlights the importance of ophthalmoscopic examination in diagnosing a potentially fatal systemic disease.

Abstract
The relationship between organisms and contaminants may be a two-way interaction: contaminants affecting the biota and the biota affecting the environmental fate and distribution of the contaminants. This may be especially so for sediment-dwelling organisms, because their burrowing and feeding can drastically influence sediment characteristics. The present study looked at the influence of the suspension-feeding stout razor clam Tagelus plebeius on the distribution of crude oil and pyrene in greenhouse mesocosm experiments. Water column turbidity and sediment redox also were monitored during the 15- to 30-day exposures to provide information on the influence of hydrocarbons and the razor clams on environmental conditions. For the experiment with crude oil, sediment was taken from the mesocosms at the end of the experiment, and the hydrocarbon-degradation potential was assessed in incubations with 14C-naphthalene. The experiments used four treatments: hydrocarbons present/absent and razor clams present/absent. Hydrocarbon dosing levels were relatively low (1 mL of oil or 30 mg of pyrene per mesocosm with 22 L of natural sediment and 11 L of seawater). The presence of the razor clams resulted in hydrocarbon concentrations at the sediment surface being 25% lower than in mesocosms without clams. No consistent effects were noted for polycyclic aromatic hydrocarbon (PAH) concentrations in the water column or in subsurface sediment. The naphthalene-degradation potential was elevated for sediment from mesocosms dosed with oil, but the presence of the clams did not affect this potential. The presence of the razor clams resulted in a lowering of water column turbidity, but no effect on sediment redox. The hydrocarbon addition had no effect on turbidity, but sediment redox was lowered. While results show that the presence of the razor clams resulted in a loss of hydrocarbons from the surface sediment, the other results do not provide a clear picture of the underlying mechanisms and the fate of the PAHs lost from the sediment surface. We hypothesize that the loss of surface sediment PAHs was due to burial of surface sediment and possibly bioaccumulation by the clams. While additional research is needed for further insights into underlying mechanisms, the present work demonstrates that the presence of sediment-burrowing suspension feeders decreases hydrocarbon levels in surface sediment. This means that assessments of the impact of an oil spill should pay attention to effects on these organisms and to their influence on the fate and distribution of the spilled oil.

Abstract
We conducted a cross sectional study to examine the association of intestinal parasitic infections and protein energy malnutrition (PEM) with iron-status indicators and anaemia among Orang Asli children in Selangor, Malaysia. A total of 281 children aged 2 - 15 years were studied. The data were collected using structured questionnaires, anthropometric measurements and laboratory analysis for blood and faecal samples. All children were infected either by A. lumbricoides, T. trichiura or hookworm and almost 19%, 26% and 3% of the children had severe infection of ascariasis, trichuriasis and hookworm infection respectively. The prevalence of giardiasis among them was 24.9%. Overall, 41.5% of the children were anaemic (haemoglobin < 11.0 g/dL). Of these 61.0% of the children had iron deficiency and 36.5% had iron deficiency anaemia (IDA), which accounted for 88.0% of anaemia in this population. Severe trichuriasis had the most significant correlation with anaemia and iron deficiency in this population. It contributed to low concentrations of haemoglobin, serum iron and serum ferritin and high total iron binding capacity (TIBC). Significant underweight and stunting were associated with low concentrations of haemoglobin and serum iron while significant wasting was significantly associated with low concentration of serum ferritin. Logistic regression analysis confirmed that severe trichuriasis was a strong predictor of IDA. It also confirmed that children who were significantly underweight and whose mother was working were independent predictors of IDA in this population.

Abstract
This study aims to determine the prevalence of protein-energy malnutrition and its association with soil-transmitted helminthiases in Orang Asli (Aborigine) children in Selangor, Malaysia. The results obtained from 368 children aged 2-15 years showed that the overall prevalence of mild and significant underweight was 32.1% and 56.5% respectively. The prevalence of mild stunting was 25.6% while another 61.3% had significant stunting. The overall prevalence of mild and significant wasting was 39.0% and 19.5% respectively. The overall prevalence of ascariasis, trichuriasis and hookworm infection were 61.9%, 98.2% and 37.0% respectively and of these 18.9%, 23.5% and 2.5% of the children had severe infection of the respective helminthes. The overall prevalence of giardiasis was 24.9%. The present study vividly shows that stunting and underweight are highly prevalent among Orang Asli children and therefore of concern in this community. In this population intestinal parasitic infections, especially severe trichuriasis and giardiasis, were identified as the main predictors of stunting and wasting respectively, in addition to age between 2 to 6 years.
