Objective: to understand the experience of families in the care of children with myelomeningocele., Method: a qualitative research study, which adopted Symbolic Interactionism and Grounded Theory as its theoretical and methodological framework, and the semi-structured interview as a data collection instrument. Twenty-eight participants from thirteen families living in a municipality in the inland of São Paulo took part in the study., Results: the family tirelessly seeks better health and life conditions for the child with myelomeningocele; aiming at the child's autonomy, it is mobilized to the necessary treatments, to learn the care, to adapt the routine, as well as to supply for all the child's needs so that it reaches potential development, looking for a less dependent future with inclusion and social ascension., Conclusion: family nursing shows potential support in the face of myelomeningocele, due to its ability to apprehend the family system, evaluate it and enable intervention proposals in the care process. In this study, rehabilitation nursing was also emphasized, since it goes together with the child and the family who experience myelomeningocele.

Aim: To understand what the absence of the family during emergency care means to adult patients and their families to., Method: A grounded theory study was conducted in two emergency units of two public hospitals in southern Brazil. From October 2016 to February 2017, 15 interviews with patients and 15 with family members were carried out. The data were analyzed following the comparative method., Results: The patients and families experienced the absence of the family in emergency care as a process of suffering caused by the separation of patient and family; they did not understand the reasons for family exclusion, and were resigned to the situation., Conclusion: Urgent care per se entails suffering in patients and their relatives; this suffering intensifies when the family is separated and cannot accompany the patient during emergency care. These results show the need to develop health strategies and policies that contribute to the comprehensive care of patients and families in hospital emergency units., (Copyright © 2019 Sociedad Española de Enfermería Intensiva y Unidades Coronarias (SEEIUC).

Objectives: to know the meaning attributed by family members to the health safety of pediatric patients, with attention to the possibilities of their collaboration., Methods: this qualitative study was conducted with eighteen family members of children hospitalized in a pediatric unit, from January to July 2018. Symbolic Interactionism was used as a theoretical framework, and Inductive Content Analysis as method., Results: child hospitalization poses risks to possible incidents and adverse events. Participants and professionals are responsible for patient safety. Thus, their actions focus on error prevention. Therefore, they seek information and observe in a vigil way professional care in classic aspects of safety. They conceive essential and favoring safety the approach centered on children and family members. Final Considerations: family members recognized the chances of errors and care damage, identified themselves as support in minimizing damage and were in partnership with the professional, increasing chances of effecting safety.

Objective: to understand the experience of families about school experiences of children and adolescents with visual impairment., Method: a qualitative study developed through the Symbolic Interactionism and narrative research. Data were collected through a semi-structured recorded interview, with eleven families of children/adolescents with visual impairment, totaling 40 participants., Results: two phenomena emerged: "exclusion context" and "impaired school performance". Prejudice experienced at school brings devastating consequences to the life of the visually impaired child/adolescent and his family. Isolation occurs, difficulty adapting to the support resource and deficits in school performance., Final Considerations: production contributes to awakening professionals involved with the assistance of these people. Effective participation of health professionals in this area is required to develop actions with students, teachers and families, aimed at meeting the needs of learning and health promotion, inclusion, and respect for differences.

Objective: To explore factors that interact and shape the meaning and experience of mothers of HIV-exposed children in relation to replacing breastfeeding by infant formula., Method: A qualitative study was carried out with 23 mothers living with HIV, whose children were up to 18 months of age and under follow-up in a specialized care service. Symbolic Interactionism, semi-structured interviews and content analysis were adopted as theoretical framework., Results: The social symbols of breastfeeding, the (un)availability of the milk formula and the (lack of)support of health professionals influenced the mothers' experience with formula feeding. Social, cultural and economic constraints have proved capable of undermining the conditions necessary for the replacement of breastfeeding., Final Considerations: The availability of infant formula, access to lactation inhibitor and quality of health services still represent challenges to eradicate new HIV infections in children.

Objective: To know the composition and functioning of the social support used by the family of children with pneumonia., Methods: A qualitative study was carried out with fourteen families of children under five years old hospitalized for pneumonia, coming from regions of greater social vulnerability in a city in the state of São Paulo, from November 2015 to May 2016. The theoretical reference used was the Calgary Family Assessment Model, and the Bardin Thematic Content Analysis was used as method., Results: The nuclear family and the extended family constitute the social support used; the support network accessed includes the Primary Health Care, Emergency Care Units and hospitals, observing intersectoral referral and counter-referral failure., Final Considerations: The family reorganization proved to be relevant and effective in times of crisis; the families seek the secondary level of health care to solve the illness of their child.

Purpose: To understand the benefits of cochlear implantation in adulthood under the perspective of users., Methods: Qualitative study using Symbolic Interactionism and Straussian Grounded Theory as theoretical and methodological frameworks, respectively. The project was approved by the Research Ethics Committee of the aforementioned Institution (Opinion no. 482,019). Sixteen adult cochlear implant (CI) users aged 28-58 years participated in the study. The data collection instrument was a semi-structured interview with questions about changes caused by CI in the social relations, communication, family system, and personal, academic and professional spheres of life of users., Results: The category Cochlear Implant Effects on Adulthood is part of a more comprehensive theoretical study that addresses how adult CI users cope with deafness. Together with its subcategories, it shows that CI intervenes in a revolutionary way in the lives of its users, because it increases their sense of security, enables them to see life from a new perspective, rescues self-confidence and self-esteem, enables them to communicate and interact more effectively, enjoy music and other entertainment, rescue old projects, and make plans for the future; thus assisting with the process of recovering independence in adult life., Conclusion: Subjective impressions of the users showed that cochlear implants not only improve their auditory performance, but also bring several positive changes to their social insertion and quality of life. Therefore, this intervention is highly beneficial to deaf adults.

Objective: To understand the family's experience of a child who uses a cochlear implant (CI). Specifically, to identify the difficulties, changes, and feelings entailed by deafness and the use of the CI; the coping strategies; and to understand the role of the family for the child with a CI., Method: Qualitative research, using Symbolic Interactionism and Straussian Grounded Theory as the theoretical and methodological frameworks, respectively. Data collection instrument: semi-structured interview. A total of 9 families (32 individuals) participated in the study. The children's ages ranged from 6 to 11 years old (mean = 8.9 years old)., Results: Their experience is described in the following categories: Having to fight for results, Coping with difficult situations, Recognizing that you are not alone, Learning to overcome, and Having one's life restored by the implant., Conclusion: Cochlear implantation changes the direction of the child and the family's life by restoring the child's opportunity to hear and to obtain good results in her personal, social, and academic development. Even after implantation, the child continues to experience difficulties and requires the family's mobilization in order to be successful. The family is the principal actor in the process of the child's rehabilitation.

Objective: to know the social network and support of those who experience the process of kidney disease and transplantation., Methods: a descriptive qualitative study, based on the concept of social network and social support from Sherbourne and Stewart. Semi-structured interviews were conducted from November 2013 to September 2014, with 12 kidney transplantees, which passed through content analysis. This study had the following selection criteria: the interviewee must have had a transplant five years ago, at most, be at lease 16 years of age and have preserved cognitive and language skills., Results: three categories were constructed from the analysis process that link the family as the main component of the social network, health service offers support in its various dimensions, even if it is occasionally disconnected; other interpersonal relationships are mentioned as vulnerable in this process; spirituality helps in coping., Conclusions: despite the different forms of support for transplantees, weaknesses were observed in these networks and social supports.

This study aimed to understand the interactions established between social support networks and families that have children and adolescents with visual impairment, in two different cities in the state of Sao Paulo, Brazil. This was a qualitative, descriptive study with symbolic interactionism as a theoretical framework. A genogram, ecomap and semi-structured interviews with 18 families were used. The method adopted for data analysis was narrative analysis. Two themes were found: potentials derived from the relationship with the support network, and, counterpoints in the support network. The family members accessed other members of their own family, friends, spiritual and cultural activities, health services, government institutions, and philanthropic organizations as support networks. The weakness in health services support is an obstacle to comprehensive healthcare for children and adolescents living in city A. In city B, other possibilities exist because it has a reference service. Despite the weaknesses in the support network in both cities, the family articulates and develops a foundation so that they can provide the best situation possible for their child or adolescent. It is up to health professionals to provide support to families and empower them to care for their members.

Objective: to understand the experience of mothers of technology-dependent children as regards pharmaceutical care., Method: this was a qualitative, descriptive-exploratory study developed based on open interviews using a structured characterization tool, and applied during home visits to 12 mothers caring for technology-dependent children. The data was submitted to inductive content analysis., Results: this study is split into two themes: (i) maternal overload during pharmaceutical care, demonstrating the need to administer drugs continuously and the repercussions of this exhaustive care on the caregivers; (ii) the ease or difficulty of access to the medicines required, showing informal strategies and support networks., Conclusion: pharmaceutical care is a daily challenge expressed in maternal overload and difficulty accessing the drugs, made worse by failures in the care network and coordinated care.

The reaction pathway of the cyclization of 2-phenoxybenzophenone into 9-phenyl-9H-xanthen-9-ol in the presence of acid and an excess of AlCl33 was studied using density functional theory. This type of reaction is known to occur during the Friedel-Crafts polycondensation of poly(aryl ether ketones) following the undesired benzoylation of nucleophilic positions ortho- to the growing polymer's ether groups. The formed defect acts as an undesired terminator of the polymer chain, causing severe problems in the polymer's melt state. A branched, multistep mechanism reminiscent of the Friedel-Crafts acylation reaction is discovered; the reaction starts with the protonation of the carbonyl oxygen, followed by intramolecular electrophilic attack on the carbonyl carbon that determines the turnover frequency of the catalytic cycle and ends by deprotonation of the Wheland intermediate.

Objective: To learn about the experience of caregivers/mothers providing care to infants exposed to HIV through vertical transmission., Methods: This qualitative study used Symbolic Interactionism as the theoretical framework. A total of 39 caregivers of children exposed to HIV in follow-up at a specialized service were interviewed. Data were analyzed through inductive content analysis., Results: Four categories were identified that report on the lonely experience of handling the child's antiretroviral therapy, mainly due to a lack of information or incomplete information; being attentive to required care, such as the use of prophylaxis for pneumonia, vaccines, and other practices restricted to the mother-child interaction; the desire to omit the HIV out of fear of prejudice and fear of the disease, considering future prospects., Conclusion: The HIV and the threat this infection may affect the child cause apprehension and feelings such as fear, guilt and anxiety in the caregivers. Healthcare workers need to work together with mothers so they are able to cope with demands and distress. Only then will the treatment to avoid vertical transmission be efficient and will mother and child be supported during the process, despite apprehension with the outcome.

During and after pregnancy, mothers with HIV can undergo treatment that is capable of preventing vertical transmission (VT) to their babies. The purpose of this study was to analyze the experience of family members that provide care for children whose mothers have HIV, to reduce the risk ofVT, with emphasis on the beginning of this trajectory. This study was based on the qualitative approach and Symbolic Interactionism was adopted as a theoretical framework. A total of 36 family members participated in the study, all of whom were carers of children aged up to 18 months and waiting for confirmation of the HIV diagnosis. Data were collected in a hospital in north-eastern Brazil, between December 2012 and February 2013, and examined by means of content analysis. Child care began during pregnancy, when the possibility of the child having HIV was expected. Some had previous experience in providing care for exposed children. Understanding the early trajectory of care will help find ways to provide better support for carers during the trajectory of diagnosis confirmation.

Objective: to understand the meanings the family attributes to the phases of the decision-making process on a cochlear implant for their child., Method: qualitative research, using Symbolic Interactionism and Grounded Theory as the theoretical and methodological frameworks, respectively. Data collection instrument: semistructured interview. Nine families participated in the study (32 participants)., Results: knowledge deficit, difficulties to contextualize benefits and risks and fear are some factors that make this process difficult. Experiences deriving from interactions with health professionals, other cochlear implant users and their relatives strengthen decision making in favor of the implant., Conclusion: deciding on whether or not to have the implant involves a complex process, in which the family needs to weigh gains and losses, experience feelings of accountability and guilt, besides overcoming the risk aversion. Hence, this demands cautious preparation and knowledge from the professionals involved in this intervention.

Decarboxylative cross-coupling reactions of substituted 2-carboxyazine N-oxides, with a variety of (hetero)aryl halides, by bimetallic Pd(0)/Cu(I) and Pd(0)/Ag(I) catalysis are reported. Two possible pathways, a conventional bimetallic-catalyzed decarboxylative arylation, as well as a protodecarboxylative/direct C-H arylation sequence have been considered. These methods provide the first general decarboxylative arylation methodology for the 2-carboxyazine series., (© 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.)

The objective of this study is to characterize how the Family Health Strategy teams in Brazil perceive their role to provide continued care to families of children with chronic diseases. This was a qualitative study that used symbolic interactionism as its theoretical framework, with content analysis for thematic categorical analysis. Focus groups with three Family Health Strategy teams were used for data collection, with a total of 32 study participants. The results were organized into three thematic categories: 1) singularities of families that live with children with chronic diseases; 2) team, family and Family Health Strategy; and 3) limitations of care . The teams' perception is that the design of the Family Health Strategy encourages access to the family experience, allowing the recognition of its specificities. Further, the data reveal team limitations regarding their capacity to provide care, and the need for investments in articulation with different social services, sectors, and equipment.

The reaction pathways of several Friedel-Crafts acylations involving phenyl aromatic compounds were studied using density functional theory. The reactions were related to the Friedel-Crafts polycondensation of polyaryletherketones. In particular, the acylation of benzene with benzoyl chloride to form benzophenone and variations on this reaction were investigated. The acylation of benzene by one molecule of terephthaloyl chloride or isophthaloyl chloride as well as acylations at the m-, o-, and p-positions of diphenyl ether with one molecule of benzoyl chloride were studied. Adding an additional acyl chloride group to the electrophile appeared to have little influence on the reaction pathway, although the activation energy for the C-C bond-forming steps that occurred when isophthaloyl choride was used was different to the activation energy observed when terephthaloyl chloride was used. Upon changing the nucleophile to diphenyl ether, the reactivity changed according to the trend predicted on based on the o-, p-directing effects of the ether group. The deprotonation step that restored aromaticity varied widely according to the reaction. The rate-determining step in all of the studied reactions was the formation of the acylium ion, followed in importance by either the formation of the Wheland intermediate or the abstraction of hydrogen, depending on the reactivity of the nucleophile.

The purpose of this study was to learn the perception that families of children with a chronic disease make of their relationships with the Family Health Unit (FHU). This qualitative study was performed using symbolic interactionism as the theoretical ground and narrative inquiry as the method. Data were collected through semi-structured interviews with seven families of children with chronic disease, enrolled in the FHU of a region with high social vulnerability, in Sdo Paulo state, Brazil. Results showed that the family's relationship with the FHU is influenced by elements from their experience and trajectory, and that their experience as a family of a child with a chronic disease is strongly marked by their relationship with the health care services. This has great influence on the responses of the family, thus requiring a systematic and committed engagement of the health system in relieving their suffering, beyond merely treating the disease.

The prevalence of chronic disease in childhood has increased, placing families in constant contact with health professionals. In such situations the relationship with health professionals has an important role. Few scientific studies address this theme, in spite of its being highlighted as fundamental for effective interaction. The aim of this study was to characterize how the family of a child with a chronic disease perceives its relationship with health professionals. Twenty caregivers for children with chronic diseases were interviewed. The theoretical and methodological frameworks were, respectively, symbolic interactionism and thematic content analysis. The analytical process revealed four themes: role of the caregiver, stressful relationships, services and professionals, and seeking welcoming relationships. The outcomes of this interactional process, which show an incongruity of expectations and behaviors between professionals and families, are poor and generate feelings of abandonment. These can be eased through listening and understanding by other families in similar situations.

Objective: to describe and to analyze the experience from families of children with cerebral paralysis living under circumstances of social vulnerability., Method: six resident families in area with this characteristic were interviewed. It was opted to use the Symbolic Interactionism as theoretic reference and the Thematic Content Analysis of Bardin as analysis method for the data., Result: the experience of such families is represented in the subjects: Reorganizing the Life, with the categories "Discovering the way" and "Accommodating the routine", and Stopping a Constant Fight with the categories: "Primary Carer being overcharged", "Coexisting with the preconception", "Having locomotion difficulty" and "Living with financial difficulties"., Conclusion: the social vulnerability influences how the family bears the chronic condition. Professionals and strategies of public health are a power to minimize impacts including those related to the family budget, but they have not been effective. They need to be sensitized to become supporting resources, to offer and to guide the access to the support networks and to spur the social service in action when necessary. This study adds knowledge to the already existing by pointing out peculiarities of the family experience in situations regarding two variables of difficult handling: chronicity and social vulnerability, evidencing the role of the professional in search of the solution for the confrontation of demands and sufferings together with the family.

With the aging of the population, it is important to identify how other age groups perceive the elderly. The objective of this quantitative, cross-sectional and descriptive study was to evaluate the attitude of children living with seniors toward aging. Interviews were conducted with 54 children, aged between seven and ten years old, living with elderly people. After sociodemographic data were collected, the Todaro Scale for the Assessment of Attitudes of Children Toward the Elderly was applied. It assesses the domains of persona, cognition, social interaction, and agency. Most children were nine years old, male and had lived with an elderly individual for at least five years. The results showed positive attitudes. The persona domain was associated with 'time living with a senior.' This study's results support health professionals in planning educational interventions, designed to maintain and improve the attitudes of children toward the elderly.

Both base-assisted non-concerted metallation-deprotonation (nCMD) and concerted metallation-deprotonation (CMD) have been identified as two potent operating mechanisms in palladium-catalysed direct C-H coupling of oxazole and thiazole-4-carboxylate esters with halides through base- and solvent-effect experiments. Novel C2- and C5-selective CMD direct arylation procedures in oxazole- and thiazole-4-carboxylate series were then designed by controlling the balance between electronic and steric factors. Notably, charge interactions between the palladium catalyst and substrate were identified as a parameter for controlling selectivity and reducing the impact of steric factors in the CMD reaction., (Copyright © 2011 WILEY-VCH Verlag GmbH & Co.

This study develops a theoretical model concerning the experience of families of children with Down syndrome in preschool and school age. The frameworks used were Symbolic Interactionism and Grounded Theory. Semi-structured interviews were used as the instrument of investigation and ten families participated in the study. The Theoretical Model "Seeking the child's independence and autonomy through constant stimulation" was identified, which shows the family's efforts to enable the child to develop the best s/he can through stimulation in order to become less dependent in the future. This model can be used to facilitate interaction with the family and can be further expanded. Nurses should use spaces dedicated to care delivery to establish bonds with the family, and seek other spaces families frequent, to better meet their needs, since there are significant gaps in care and research addressing this population. Instead, they should be welcomed and seen as a partner in care delivery.

The objective of this study was to identify the evidence available in the literature that address, for children's perspective, factors that are relevant for an appropriate management of type 1 diabetes mellitus. An integrative review was performed on the PubMed, CINAHL, LILACS, CUIDEN and PsycINFO databases, covering the period from 1998 to 2008 and using the following keywords: type 1 diabetes mellitus, child, prevention and control, triggering factors, emergencies, self care, learning and health education. Nineteen of the surveyed articles were selected, and their analysis revealed the following categories: living with diabetes; self care and glucose profile; the actions of family, friends and health professionals; and school. The evidence show that children appreciate the support they receive from their relatives, which have a direct relationship with being prepared for self care. Other members apart from their network are also valued. Areas that deserve attention are the school, the personal experience of each child, and health education.

This article reports on the experience of a group of nursing faculty on the development of a project aimed at adolescent maternity with a view to prevent unwanted pregnancies. An additional proposal of the referred project is guiding adolescent mothers in terms of self-care, care with their babies, and encouraging exclusive breastfeeding. This would reduce the difficulties that those young mothers experience and, therefore, contribute with the maternal-child area.

The purpose of this study was to understand how the family faces the challenge of having a child with Down Syndrome among its members, so that, from this understanding, nurses can propose and carry out a careful emphasis on family responses to current and potential problems experienced. Symbolic Interactionism and the initial steps of Grounded Theory were used. The study comprised eight families and the results of a phenomenon were presented: "Going though cloudy periods" and its categories: "Faced with the unimaginable", "Adapting to the new reality" and "Living with disappointments". Throughout the experience, families face periods of uncertainty and doubt, requiring new attitudes and coping with the unknown. Health professionals, specifically in nursing, have remained outside the work done with these families. The need to guide and support such families is vital, particularly in coping with periods of difficulties and doubts, in order to minimize and possibly avoid them.

Network and social support are resources that nursing can offer to families. This review identifies which aspects of social support are being investigated for the family of the cancer patient. Fifty one articles were found of which 70% were quantitative research and 26% were published in the last two years. The issues addressed were: Family caregivers as provider of social support; Factors that interfere with social support; Religiosity as social support as well as support coming from educative programs, group activity and technological resources. Of these papers, 49% were written by nurses, with international emphasis on needs assessment, family experiences and support offered, while national articles emphasize definition concepts and identifying family needs focusing on intervention planning.

In spite of numerous reports dealing with the use of 1,4-dihydropyridines as carriers to deliver biological active compounds to the brain, this chemical delivery system (CDS) suffers from poor stability of the 1,4-dihydropyridine derivatives towards oxidation and hydration reactions seriously limiting further investigations in vivo. In an attempt to overcome these limitations, we report herein the first biological evaluation of more stable annellated NADH models in the quinoline series as relevant neuroactive drug-carrier candidates. The radiolabeled 1,4-dihydroquinoline [(11)C] was prepared to be subsequently peripherally injected in rats. The injected animals were sacrificed and brains were collected. The radioactivity measured in rat brain indicated a rapid penetration of the carrier [(11)C] into the CNS. HPLC analysis of brain homogenates showed that oxidation of [(11)C] into the corresponding quinolinium salt [(11)C] was completed in less than 5 min. An in vivo evaluation in mice is also reported to illustrate the potential of such 1,4-dihydroquinoline derivatives to transport a neuroactive drug in the CNS. For this purpose, gamma-aminobutyric acid (GABA), well known to poorly cross the brain blood barrier (BBB) was connected to this 1,4-dihydroquinoline-type carrier. After i.p. injection of 1,4-dihydroquinoline-GABA derivative in mice, a significant alteration of locomotor activity (LMA) was observed presumably resulting from an enhancement of central GABAergic activity. These encouraging results give strong evidence for the capacity of carrier-GABA derivative to cross the BBB and exert a pharmacological effect on the CNS. This study paves the way for further progress in designing new redox chemical delivery systems.

This study aimed to understand the experience of caring for a child with a congenital anomaly from the family's perspective. Symbolic Interactionism and Grounded Theory were the theoretical and methodological references, respectively. Data collection was carried out with eight families with children having congenital anomalies through semi-structured interviews and participating observation. Data analysis reached axial coding. Results revealed two phenomena in the experience of families in delivering care to children with congenital anomalies--facing an initially difficult experience and suffering eases over time. We concluded that the understanding of this experience supports the need to reconsider the nursing care provided to families in the care of children with congenital anomalies.

A efficient methodology allowing the one-pot stereoselective synthesis of alpha-fluoroacrylates, based on the addition of ethyl dibromofluoroacetate to a carbonyl derivative using diethylzinc as organometallic mediator, is described. Two different pathways have been identified depending on the involved carbonyl partner. In the case of aldehydes, an E2-type mechanism has been identified, whereas ketones go through an E1cb-type mechanism.

Enantiomer separations of underivatised amino acids were carried out by using ligand exchange capillary electrophoresis (LECE). Chiral discrimination is based on the formation of ternary complexes between copper(II), a chiral selector (L-proline or trans-4-hydroxy-L-proline) and an amino acid. All amino acids containing aromatic moieties or not were detected at 214 nm because of their interactions with copper(II). In order to reduce copper(II) adsorption onto capillary walls, we used hexadimethrine bromide to reverse the electroosmotic flow. Using this original strategy, the studied enantiomers migrated in the opposite direction of the anodic electroosmosis. After optimising the analytical conditions taking into account the chiral resolution and the detection sensitivity, we performed very satisfactory enantioseparations not only of aromatic amino acids (tryptophan, tyrosine, phenylalanine and histidine) but also of aliphatic amino acids (threonine, serine, isoleucine and valine). These enantioseparations were performed in a short analysis time at 35 degrees C. In order to rationalise the obtained results, we evaluated the complexation constants corresponding to the formed ternary complexes by capillary electrophoresis and we used molecular mechanics modelling.

This work reports the synthesis of new axially chiral bridged 2,2'-bipyridines 1 and pyridylmonooxazolines (pymox) 2. The potential of these new axially chiral N,N-ligands was evaluated in asymmetric catalytic cyclopropanation of styrene derivatives 22a-c with diazoesters 21a,b. While 2,2'-bipyridines 1a-c afforded the corresponding cyclopropanes 23a-f in up to 65% ee, pymoxs 2a-e gave somewhat lower enantioselectivities (up to 53% ee). Both classes of ligands produced trans-cyclopropanes 23a-f as the major isomer, although with modest diasteroselectivities (56 : 44 to 78 : 22). A structure-stereoselectivity relationship study of ligands 1 and 2 identified the chiral biaryl axis as being mostly responsible for the enantioselective performances of these ligands.

[reaction: see text] Conjugate addition of aryl or alkyl cuprates to 3,4-dimethyl-5,6-dihydro-2(1H)-pyridinones led to diastereoisomerically pure 3,4,4-trisubstituted 2-piperidinones in 39-78% yields. The yields and the diastereochemistry of piperidinones depended on both the N-protecting group and the organocuprate. Reduction then deprotection of the trans-3,4-dimethyl-4-phenyl product provided the corresponding piperidine, analogue of a key precursor of opioid receptor antagonists.

A solid phase approach for the preparation of peptides attached to a redox chemical delivery system derived from stable annulated NADH models is reported. The synthesis starts with the grafting on a Merrifield resin of quinoline 4b, precursor of the redox carrier. From the resulting quinoline supported resin 4d, the stepwise SPPS of both octapeptide OP (RPGLLDLK) and octadecaneuropeptide ODN (QATVGDVNTDRPGLLDLK), two neuropeptides exhibiting anorexigenic effects, was successfully achieved by conventional methods. Quaternization of the quinoline moiety prior to cleavage of the modified OP and ODN peptides from the resin, led to the expected quinolinium salt 8a and 8b respectively linked to OP or ODN peptides. Finally, the reduction with NaBH4 monitored by UV-vis, provided the desired annulated NADH models as peptides carriers with either the OP (11a,b) or ODN (12a,b) moiety.

Diabetes mellitus is a chronic disease that demands adaptation in the psychological, social and physical sphere. This study aimed to understand the experiences of children with the disease. Symbolic Interactionism and Grounded Theory were used as a theoretical and methodological reference framework, respectively. We interviewed children in the age group between 7 and 14 years old. A total of 7 topics were identified in the collected data, which were: "Experiencing something unexpected", "Facing a harsh reality", "Being afraid of what is happening", "Living under control", "Trying to adapt to a new reality", "Maturing with this close relationship" and "Seeing this disease from a different angle". Living with diabetes is something these children are confronted with daily from the very moment it is diagnosed, having to live with a restricted diet, insulin therapy and life style changes, facts that bring about feelings that range from fear to insecurity, to revolt, to acceptance and adaptation.

A new and unprecedented exploitation of quinolinium thioester salts 2 in peptide bond formation is reported. These synthetic tools were assessed during the preparation of a number of dipeptides 3a-f obtained in good yields with complete stereochemical integrity. A sequential mechanism related to a prior amine capture strategy is well-established. Additionally, a tripeptide 3g was prepared according to a "safety-catch" approach, thus demonstrating the important potential of these new synthetic tools in the design of new safety-catch linkers exploitable in Solid-Phase Peptide Synthesis (SPPS).

The 3-chloropyridazine moiety was immobilized on a Wang resin, using two different methodologies. The first of these involved direct nucleophilic substitution of 3,6-dichloropyridazine with the alcoholate of Wang resin. The experimental conditions were optimized. The second method involved a Mitsunobu reaction between the Wang resin and 6-chloropyridazin-3-ol during which a problem of regioselectivity was observed. The so-obtained chloropyridazine-containing resins were subsequently reacted with various arylboronic acids under Suzuki conditions. Acid cleavage yielded 6-arylpyridazin-3(2H)-ones with high chemical purity.

This research was motivated by the need to know more about the care of children with cancer. The objective of the study was to discover what the social representation of the child with cancer are. Ten open interviews were conducted with children and teenagers from 9 to 15 years of age. The analysis issues that emerged from the children's discourse were about the disease, the treatment, the health care workers and family relationships. The present study presents the social representation of the disease, with the objective of better understanding the topic and directing nursing care towards a minimization of the trauma which this process brings upon the children.

A novel extension of Meyer's lactamization is reported for the preparation of seven-membered ring lactams 1a-d incorporating a biaryl unit. The required keto-esters 2a-c were readily accessible via the Suzuki coupling reaction. A borylation-Suzuki coupling (BSC) sequence was successfully developed for the high-yielding preparation of keto-ester 2d. Cyclization of the resulting keto-esters 2a-d or keto-acids 5a,c,d in the presence of (R)-phenylglycinol afforded the desired lactams 1a-d in high yields (72-93%) and excellent diastereoselectivities (>95%). This methodology provides a facile stereoselective access to new axially chiral bridged biaryls.

This study aimed to understand the meaning of health and disease for the child in the age range from 7 to 12 years old. The population was divided in two groups. The first group consisted of children in a school environment, while the second consisted of hospitalized children. This study was based on Symbolic Interactionism as a theoretical framework and on Grounded Theory as a methodological framework. Data were collected by means of semi-structured interviews, since this allowed us to explore the definitions exposed by the child. We perceived that, in both groups, the definition of health is similar, that is, in other words, something that provides them freedom and is conditioned by body care and feeding. About the conception of disease, the school child tries to understand the disease, its causes and consequences. Hospitalized children tell their experiences by focusing on their own disease and situation.

[reaction: see text] A new solid-phase synthesis of quinolines based on a Friedländer-type reaction between the resin-bound azomethine 1b and ketones 2 is described. This cyclative cleavage approach affords quinolines 3a-f in 50-81% yields. The polymer-bound aniline equivalent is easily recycled and may be reused with comparable performance.

Asymmetric reduction of methyl benzoylformate by a new NADH mimic is reported; depending on the hydride source used to reduce the NAD+ precursor, NADH mimics so obtained lead to an inversion of enantioselectivity, affording either (R)-methyl mandelate in 88% ee or (S)-methyl mandelate in 78% ee.

The aim of this study was to know the experience of the institutionalized child and was guided by the theoretical referential of the "Symbolic Interactionism" and by the methodological referential of the "Grounded Theory". The data had been collected in two stages: the first one understood group activities and second stage consisted of personal interviews. The results had shown that the institutionalization occurred for abandonment and reject of the parents or for legal decision as a measure of child protection, having as context the poverty of its family. The child's experience is conflicting in relation to being institutionalized, because while he/she perceives the necessity of material gain, they miss their family, their home, their friends, and simply life outside.

Highly diastereoselective protonation of chiral lactam enolates of 4-substituted-1,4-dihydroisoquinolin-3-ones is reported. Protonation and alkylation processes of these lactam enolates derived from phenylglycinol occur with opposite diastereofacial selectivity. This diastereoselective protonation has been applied to the asymmetric synthesis of (4S)-N-methyl-4-phenyl-1,2,3,4-tetrahydroisoquinoline 9 obtained in up to 97% ee.

This report discusses the nursing activities developed by a group of professionals within the family context. Children and their families maintain relationships determined historically by the social context within which they live. According to the National Survey by Address Sampling, 53.5% of Brazilian children and adolescents live in families whose monthly income per capita is under one half of a minimum salary. The consequences of the country's recessive economy have a serious effect upon the entire population, potentially interfering in the family's health and, thus, in that of children and adolescents. When working with families we must consider what the family believes to be its function, since, despite the fact that the Children's and Adolescent's Statute gives the legal definition of family obligations, it is the family's beliefs that actually direct or define the role it plays in caring for and protecting each of its members. The "Support Couples" project, directed by this group, takes into consideration a family's particular characteristics so that it can offer support to the family to help it meet those legal requirements related to child and adolescent care. The objective of this work is to divulge the Project itself, and to place professional nurses in activities that are directly related to the promotion and maintenance of children's and adolescent's rights as citizens inserted into a family and social context.

The nurse should combine, in their daily practice, technical abilities with a profound comprehension of the main object oh their work, the human being. Symbolic Interactionism is an approach which enables the nursery professional to understand patients by the meaning they value their living experiences. The use of qualitative methods in nursery research is essential because it studies the humans beings and their relationship with the environment, allowing the understanding of the living experiences. These kind of approaches should be even more applied in nursery practice as they open new ways for professional knowledge and enrich practical skills.

The present work reports an initial process of nursing assistance systematization developed in a Pediatric Unit of a medium size hospital in São Carlos-SP, considering the actual human resources and the type of approach adopted by the institution on the assistance given to the hospitalized child. A Routine Manual was elaborated based on the literature and with the staff participation, and after that, a training was realized with these employees, starting from routines previously sketched, using groupal dynamics that looked forward to rescue the knowledge that they already had about the themes. The work considered the employees opinion about their participation in the systematization process.

This study aimed at presenting a number of theoretical considerations related to ethnographic investigation viewing the disclosing of that type of nursing research. This study shows the definitions provided by various authors in addition to the methodology aspects regarding this type of approach.
