Quality of life in children and adolescents with congenital heart disease. A new challenge for parents, professionals and community

The Quality of life is currently a major topic discussed in our society. The World Health Organization (WHO) has been developing a unifying and transcultural definition of QOL. They considered it as 'the individual's perception of his or her position in life, within the cultural context and value system he or she lives in, and in relation to his or her goals, expectations, parameters and social relations. It is a broad ranging concept affected in a complex way by the person's physical health, psychological state, level of independence, social relationships and their relationship to salient features of their environment (WHOQOL, 1997, p. 1). Congenital heart disease is the most prevalent congenital disease in Portugal. Despite the advances in cardiac treatment and an early correct diagnosis that could increase the survival of children with congenital heart disease, this condition influences the quality of life of children, adolescents and their parents. Knowing the perception of quality of life could help healthcare professionals, nurses in particular, providing suited care to the needs of these families, establishing priorities in their interventions, sensing predictors of a poor quality of life, promoting adherence to treatment and boosting compliance with treatment, and fostering greater satisfaction for these children, adolescents and their parents. Purpose As part of broader research and with the awareness that the chronic conditions could impact the quality of life and considering that all advances on treating congenital cardiac diseases we have defined this main objective: To determine the quality of life in children and adolescents with congenital heart disease (CHD) and the perception of their parents, as well as factors that influence it. Methods It is a quantitative, descriptive and correlational research. The data collection tool was a questionnaire, which consisted of four parts: socio-demographic and educational characteristics, clinical characteristics, and quality of life, obtained using the Pediatric Cardiac Quality of Life Inventory - PCQLI - (Marino, Tomlinson, Wernovsky, Drotar , Newburger, Mahony et al., 2010) translated into Portuguese. Data collection took place between February and July 2014, in compliance with ethical research guidelines. The sample comprised 59 children, 59 parents of children, 80 adolescents and 80 parents of adolescents. Results The results indicated that children, adolescents, and their parents have high level of perceived health. The results are similar in all groups: children and parents and adolescents and parents. In the group of children, we observed the classification of "Good" in 66.10%, followed by the "Very Good" at 18.65% and "fair" in 15.25% of cases. The parents of the children responded in about half the cases that the health of their children was "good" (50.85%), "very good" in 30.51% "fair" in 11.86% and "Excellent "in 6.78%. In turn, the group of adolescents can be seen that 46.25% rate their health as "good", 32.50% as "very good", 16.25% as "Average" and 5% as "Excellent". Parents of teenagers classify the health of their children mostly as "good" in 42.50%, 31.25% as "very good", 20% as "fair" and 6.25% as "excellent". To point out that none of the respondents pointed out the option of a health status "Bad". About the quality of life, in general the results indicated that children, adolescents and their parents have high levels of quality of life, and that perceptions of parents and children are similar. Only in the children's group (8 to 12 years old), was no influence of socio-demographic, school or clinical variables on quality of life observed. For adolescents (13 to 18 years old), school, special education, school retention, the age of diagnosis of congenital heart disease, cardiac catheterization and surgical intervention influenced their quality of life. Perception of quality of life of parents of children and of adolescents was influenced by socio-demographic and clinical variables. The results partly agree with the literature in this field. About the influence of some variables: - The perception of quality of life expressed by children and adolescents with congenital heart disease and parents are related, with statistical significance. - There were no statistically significant relationships between the quality of life of children and adolescents and their age, gender or socioeconomic status. - Adolescents differ statistically significant between their quality of life and their education, the frequency of special education and the existence of grade retention. The severity of heart disease, the number of cardiac catheterizations or surgery and the presence of other health disorders are unrelated to the quality of life of children and adolescents. - Adolescents revealed that the level of quality of life is influenced by the age of diagnosis of CHD by cardiac catheterization and surgery. - For parents of children and adolescents gender and their education don´t influence their perception of quality of life. Only the socioeconomic status of parents of teens has statistically significant difference to quality of life. - Parents of children and adolescents do not show statistically significant relationship between the perceived level of quality of life and severity of disease, age at diagnosis, the number of surgical interventions and the existence of other health disorders. - There is a relationship of statistical significance between cardiac catheterization and the perceived quality of life by parents of adolescents; between the number of cardiac catheterizations and the perception of quality of life of parents of children; and between performing surgery and the perception of parents of children and adolescents. Conclusion To analyze the quality of life of children and adolescents with CHD must be a key focus of attention in caring for this population, allowing the identification of individual differences, interests, preferences, and prevent potential problems. The knowledge acquired along with clinical experience contributes to improve the quality of life of children and families, facilitating their growth, psycho-emotional development and social integration. Nevertheless, the reading and interpretation of these results must be prudent and cautious, there are limitations to this research, including: the use of a range of specific quality of life for the Congenital heart disease in children, adolescents, and parents but whose validation process could not be completed in this study; the low prevalence of severe conditions in our sample; the absence of national studies to enable comparison with the results obtained. We intend to continue the process of validation of instrument and enlarge the research to Lisbon and Oporto, other major centers where the cardiac conditions can be treated

Congenital bone malformation in a rainbow boa Epicrates cenchria crassus - case report

Bone malformation in snakes stems from inbreeding or temperature variations during gestation or incubation. Differential diagnosis are osteoarthropathy due to nutritional, metabolic and infectious diseases. For an accurate diagnosis of these changes, a radiographic exam is essential because it provides a general view of the skeleton and detects morphological abnormalities. This study aimed to report the clinical care of a rainbow boa (Epicrates cenchria crassus) with congenital kyphosis and changes in scales, from a snake pit with controlled temperature and humidity since its gestation. Multiple dorsal deviations of the column without the presence of osteoarthrosis were seen upon radiographic examination. Studies aiming to understand the cases of congenital malformation in snakes should be performed to prevent the birth of animals with this type of change.

Urinary Tract Effects of HPSE2 Mutations

Urofacial syndrome (UFS) is an autosomal recessive congenital disease featuring grimacing and incomplete bladder emptying. Mutations of HPSE2, encoding heparanase 2, a heparanase 1 inhibitor, occur in UFS, but knowledge about the HPSE2 mutation spectrum is limited. Here, seven UFS kindreds with HPSE2 mutations are presented, including one with deleted asparagine 254, suggesting a role for this amino acid, which is conserved in vertebrate orthologs. HPSE2 mutations were absent in 23 non-neurogenic neurogenic bladder probands and, of 439 families with nonsyndromic vesicoureteric reflux, only one carried a putative pathogenic HPSE2 variant. Homozygous Hpse2 mutant mouse bladders contained urine more often than did wild-type organs, phenocopying human UFS. Pelvic ganglia neural cell bodies contained heparanase 1, heparanase 2, and leucine-rich repeats and immunoglobulin-like domains-2 (LRIG2), which is mutated in certain UFS families. In conclusion, heparanase 2 is an autonomic neural protein implicated in bladder emptying, but HPSE2 variants are uncommon in urinary diseases resembling UFS.

Importancia de la morfología de las ondas del ductus venoso en el diagnóstico de cardiopatía congénita

El ductus venoso refleja el ciclo cardiaco, pero actualmente no se conoce como se comporta cada onda del ductus venoso en los diferentes grupos de cardiopatías congénitas. Se pretende evaluar la importancia de la morfología de las ondas del ductus venoso en el diagnóstico de los diferentes tipos de cardiopatías congénita, teniendo en cuenta las pacientes atendidas en la Unidad De Medicina Materno Fetal de la clínica Colombia entre enero 2012 y julio de 2014.

Aorticopulmonary septal defect in a dog: case report

Na avaliação da dispneia pós-exercício em uma cadela de 10 meses de idade, não castrada e sem raça definida, foi detectado sopro sistólico leve grau II/VI. A comunicação entre a aorta ascendente e o tronco pulmonar, observada pela presença de fluxo contínuo logo abaixo das valvas semilunares, à ecoDopplercardiografia, foi confirmada pela cirurgia. Após o procedimento cirúrgico, a cadela apresentou boa condição clínica e ausência de dispneia mesmo ao exercício. Ressalta-se a importância do diagnóstico precoce e preciso para o sucesso terapêutico. Este é o primeiro relato brasileiro dessa rara doença e a única cirurgia, bem sucedida, descrita na literatura veterinária consultada.

Obstrução intestinal congênita em cão por aderência de alça em osso púbico

Atendeu-se uma cadela, sem raça definida, com aproximadamente cinco meses de idade, apresentando anamnese com queixa de apatia e hiporexia associadas a vômitos e emagrecimento progressivo com início incerto. Ao exame físico era evidente distensão abdominal com dilatação intestinal e aumento de peristaltismo. O animal apresentava-se emaciado e subdesenvolvido, com acentuado grau de desidratação, pulso filiforme e nível de consciência reduzido. Minutos após o início do atendimento a cadela foi a óbito. À necropsia, pôde-se observar um segmento do intestino delgado atravessando o púbis e com lúmen reduzido. Tal apresentação se faz relevante por se tratar de um caso nunca antes descrito na literatura veterinária.

Transmissão congênita em cabras reinfectadas com Toxoplasma gondii

This study evaluated the potential of congenital transmission in goats experimentally infected and reinfected with Toxoplasma gondii, in three gestational stages (initial, intermediate and final). Of the 25 non-pregnant females negative for T. gondii, 20 were orally inoculated with 2.5 x 103 T. gondii ME49 oocysts. Of these, 15 pregnant females chronically infected were reinoculated, via oral, with 2.5 x 103 T. gondii VEG oocysts. Five experimental groups were formed (n=5): I, II and III (reinoculations in the initial, intermediate and final gestational stage, respectively), IV (inoculation) and V (no inoculation). Clinical and serological exams (IgG IFAT [indirect immunofluorescence antibody test]) in different days of evaluation, and bioassay and PCR were performed in all goats. In the infected goats with T. gondii a peak of 40.2°C (IV) at nine, seroconversion (IgG≥64) at 21 and stabilization (IgG<1024) at 119 days postinoculation were observed. In the reinfected goats with T. gondii occurred an increase in IgG titers (≥1,024) at 28 (I), 7 (II) and 3 (III) days post-reinoculation. During kidding were observed only in the reinfected groups: dystocia, malformation body, stillbirth and weakness, and IgG anti-Toxoplasma were detected in all and in some offsprings of the reinfected and infected goats, respectively. Tissue parasitism by T. gondii was diagnosed by bioassay and PCR in infected and reinfected goats and in their offspring. The congenital toxoplasmosis was possible in goats chronically infected and reinfected with T. gondii. The primary infection with T. gondii did not protect the pregnant goats against congenital disease resulting from toxoplasmic reinfection, in different gestational stages (initial, intermediate and final).

In vitro action of antiparasitic drugs, especially artesunate, against Toxoplasma gondii

Introduction: Toxoplasmosis is usually a benign infection, except in the event of ocular, central nervous system (CNS), or congenital disease and particularly when the patient is immunocompromised. Treatment consists of drugs that frequently cause adverse effects; thus, newer, more effective drugs are needed. In this study, the possible activity of artesunate, a drug successfully being used for the treatment of malaria, on Toxoplasma gondii growth in cell culture is evaluated and compared with the action of drugs that are already being used against this parasite. Methods: LLC-MK2 cells were cultivated in RPMI medium, kept in disposable plastic bottles, and incubated at 36 degrees C with 5% CO2. Tachyzoites of the RH strain were used. The following drugs were tested: artesunate, cotrimoxazole, pentamidine, pyrimethamine, quinine, and trimethoprim. The effects of these drugs on tachyzoites and LLC-MK2 cells were analyzed using nonlinear regression analysis with Prism 3.0 software. Results: Artesunate showed a mean tachyzoite inhibitory concentration (IC50) of 0.075 mu M and an LLC MK2 toxicity of 2.003 mu M. Pyrimethamine was effective at an IC50 of 0.482 mu M and a toxicity of 11.178 mu M. Trimethoprim alone was effective against the in vitro parasite. Cotrimoxazole also was effective against the parasite but at higher concentrations than those observed for artesunate and pyrimethamine. Pentamidine and quinine had no inhibitory effect over tachyzoites. Conclusions: Artesunate is proven in vitro to be a useful alternative for the treatment of toxoplasmosis, implying a subsequent in vivo effect and suggesting the mechanism of this drug against the parasite.

Double-chambered right ventricle in an adult patient diagnosed by transthoracic echocardiography

Abstract Background Double-chambered right ventricle is a rare congenital disease frequently misdiagnosed in the adult patient. An anomalous muscle band divides the right ventricle in two cavities causing variable degree of obstruction. Although echocardiography is considered a useful method for the diagnosis of this pathology in children, it has been recognized the transthoracic scanning limitation in adults. Case presentation A 29 year-old patient with double-chambered right ventricle presenting mild exercise intolerance referred for follow up of a known ventricular septal defect in whom a complete diagnosis was obtained based only on transthoracic two dimensional echocardiography without the needing of cardiac catheterization. Conclusion Based on non invasive echocardiographic diagnosis, patient was referred to surgical correction, which was completely successful.

Coordination of murine limb muscle, skeleton and connective tissue development by Lmx1b

The underlying genetic defects of a congenital disease Nail-Patella Syndrome are loss-of-function mutations in the LMX1B gene. Lmx1b encodes a LIM-homeodomain transcription factor that is expressed specifically in the dorsal limb bud mesenchyme. Gain- and loss-of-function experiments suggest that Lmx1b is both necessary and sufficient to specify dorsal limb patterning. However, how Lmx1b coordinates patterning of the dorsal tissues in the limb, including muscle, skeleton and connective tissues, remains unknown. One possibility is that each tissue specifies its own pattern cell-autonomously, i.e., Lmx1b is expressed in tissues in which it functions and different tissues do not communicate with each other. Another possibility is that tissues that express Lmx1b interact with adjacent tissues and provide patterning information thereby directing the development of tissues non-cell-autonomously. Previous results showed that Lmx1b is expressed in limb connective tissue and skeleton, but is not expressed in muscle tissue. Moreover, muscles and muscle connective tissue are closely associated during development. Therefore, we hypothesize that Lmx1b controls limb muscle dorsal-ventral (DV) patterning through muscle connective tissue, but regulates skeleton and tendon/ligament development cell-autonomously. ^ To test this hypothesis, we first examined when and where the limb dorsal-ventral asymmetry is established during development. Subsequently, conditional knockout and overexpression experiments were performed to delete or activate Lmx1b in different tissues within the limb. Our results show that deletion of Lmx1b from whole limb mesenchyme results in all dorsal tissues, including muscle, tendon/ligament and skeleton, transforming into ventral structures. Skeleton-specific knockout of Lmx1b led to the dorsal duplication of distal sesamoid and metacarpal bones, but did not affect the pattern formation of other tissues, suggesting that Lmx1b controls skeleton development cell-autonomously. In addition, this skeleton-specific pattern alteration only occurs in distal limb tissues, not proximal limb tissues, indicating different regulatory mechanisms operate along the limb proximal-distal axis. Moreover, skeleton-specific ectopic expression of Lmx1b reveals a complementary skeletal-specific dorsalized phenotype. This result supports a cell-autonomous role for Lmx1b in dorsal-ventral skeletal patterning. This study enriched our understanding of limb development, and the insights from this research may also be applicable for the development of other organs. ^

A cytomegalovirus-encoded mitochondria-localized inhibitor of apoptosis structurally unrelated to Bcl-2

Human cytomegalovirus (CMV), a herpesvirus that causes congenital disease and opportunistic infections in immunocompromised individuals, encodes functions that facilitate efficient viral propagation by altering host cell behavior. Here we show that CMV blocks apoptosis mediated by death receptors and encodes a mitochondria-localized inhibitor of apoptosis, denoted vMIA, capable of suppressing apoptosis induced by diverse stimuli. vMIA, a product of the viral UL37 gene, inhibits Fas-mediated apoptosis at a point downstream of caspase-8 activation and Bid cleavage but upstream of cytochrome c release, while residing in mitochondria and associating with adenine nucleotide translocator. These functional properties resemble those ascribed to Bcl-2; however, the absence of sequence similarity to Bcl-2 or any other known cell death suppressors suggests that vMIA defines a previously undescribed class of anti-apoptotic proteins.

Identification and analysis of novel genes expressed in the mouse embryonic facial primordia

Craniofacial anomalies are a common feature of human congenital dysmorphology syndromes, suggesting that genes expressed in the developing face are likely to play a wider role in embryonic development. To facilitate the identification of genes involved in embryogenesis, we previously constructed an enriched cDNA library by subtracting adult mouse liver cDNA from that of embryonic day (E)10.5 mouse pharyngeal arch cDNA. From this library, 273 unique clones were sequenced and known proteins binned into functional categories in order to assess enrichment of the library (1). We have now selected 31 novel and poorly characterised genes from this library and present bioinformatic analysis to predict proteins encoded by these genes, and to detect evolutionary conservation. Of these genes 61% (19/31) showed restricted expression in the developing embryo, and a subset of these was chosen for further in silico characterisation as well as experimental determination of subcellular localisation based on transient transfection of predicted full-length coding sequences into mammalian cell lines. Where a human orthologue of these genes was detected, chromosomal localisation was determined relative to known loci for human congenital disease.

Qualitative study of adversity activated development and resilience in adolescents and young adults with congenital heart disease and their parents

What is it like to have a medical condition that few people have ever heard about? How does it feel to have to question whether daily physical activities are dangerous for you, whilst you watch your friends enjoy those activities without a care? Can you imagine that you need to have a complicated heart surgery, with risks such as paralysis or death? Or even imagine facing the painful recovery period and scars after such a surgery? Then imagine that you are a child or teenager dealing with this medical condition when all your friends are simply occupied with school and normal life. Now consider that surgery has been undertaken to extend your lifespan, but the operation is so new that the long-term outcomes are just not known? All you really know is that you might have ‘surgical repairs’ to your heart and symptoms may be relieved or managed by medications or cardiac devices, but you are never going to be cured. What if you had already experienced painful, frightening, lonely and tedious hospitalisations and you were forced to put your life on hold to re-enter that situation, time and time again. This may be your life, as a Congenital Heart Disease or CHD patient. How do such patients cope and in many cases even thrive? This chapter will review current international literature regarding the medical and personal impact of CHD. Our qualitative study of the perspectives of young CHD patients and their parents contributes to the Australian story of CHD, as well as highlighting the potential for CHD related adversity to promote personal development.
