Maternal distress, DNA methylation, and fetal programing of stress physiology in Brazilian mother-infant pairs.

Maternal prenatal psychosocial stress is associated with adverse hypothalamic-pituitary-adrenal axis (HPAA) function among infants. Although the biological mechanisms influencing this process remain unknown, altered DNA methylation is considered to be one potential mechanism. We investigated associations between maternal prenatal psychological distress, infant salivary DNA methylation, and stress physiology at 12 months. Mother's distress was measured via depression and anxiety in early and late pregnancy in a cohort of 80 pregnant adolescents. Maternal hair cortisol was collected during pregnancy. Saliva samples were collected from infants at 12 months to quantify DNA methylation of three stress-related genes (FKBP5, NR3C1, OXTR) (n = 62) and diurnal cortisol (n = 29). Multivariable linear regression was used to test for associations between prenatal psychological distress, and infant DNA methylation and cortisol. Hair cortisol concentrations in late pregnancy were negatively associated with two sites of FKBP5 (site 1: B = -22.33, p = .003; site 2: B = -15.60, p = .012). Infants of mothers with elevated anxiety symptoms in late pregnancy had lower levels of OXTR2 CpG2 methylation (B = -2.17, p = .03) and higher evening salivary cortisol (B = 0.41, p = .03). Furthermore, OXTR2 methylation was inversely associated with evening cortisol (B = -0.14, p-value ≤ .001). Our results are, to our knowledge, the first evidence that the methylation of the oxytocin receptor may contribute to the regulation of HPAA during infancy.

The implementation of a home visits program focused on parenting: an experience report. / A implementação de um programa de visitas domiciliárias com foco na parentalidade: um relato de experiência.

OBJECTIVE: To report the experience of implementing Home Visits as part of the Young Mothers Caregiver Program. METHOD: The program focuses on the mother-child relationship as an object of care for developing parenting using the attachment theory, the self-efficacy theory and the bioecological theory as references. The construction of this program was centered on materials of international visitation programs, based on the translation of the material, elaboration and validation of the theoretical content. RESULTS: The home visits performed by the nurses lasted an average of 1 hour, where issues related to health care, environmental health, life project, parenting, family and social network, in addition to the adolescents' demands were discussed. It was shown that nurses encountered difficulties in implementing the program. CONCLUSION: By adopting Home Visits as a care tool with a focus on parenting, the experience of implementing the program proved to be an innovative technology, with great potential and relevance for promoting adolescent care and child development.

Integrated Use of Lung Ultrasound and Chest X-Ray in the Detection of Interstitial Lung Disease.

BACKGROUND: Current data have shown that lung ultrasound (LUS) may be useful in the detection of interstitial lung disease (ILD) by the evaluation of B-lines, the sonographic marker of pulmonary interstitial syndrome. Nevertheless, no prospective study has compared LUS to chest X-ray (CXR) for ILD assessment, and there is no general agreement on the specific echographic diagnostic criteria for defining ILD. OBJECTIVES: The aims of this study were (1) to compare the accuracy of LUS and CXR in the detection of ILD using high-resolution CT (HRCT) as the gold standard and (2) to compare the accuracy of different echographic diagnostic criteria for ILD diagnosis. METHODS: LUS was performed on 104 patients undergoing HRCT for suspected ILD. In 49 patients, a CXR scan performed within 3 months of HRCT was analyzed. ILD was defined as the presence of ≥5 B-lines in ≥3 chest areas. A total B-line score (TBLS) was also calculated, as in previous studies. The observers evaluating LUS and CXR were blinded to the HRCT results and clinical data. RESULTS: On HRCT, ILD was assessed in 50 patients. CXR was specific (91%; 95% CI 80-100) but not sensitive (48%; 95% CI 28-67). Conversely, LUS showed high sensitivity (92%; 95% CI 84-99) and low specificity (79%; 95% CI 69-90). Using a TBLS, sensitivity did not change, while specificity decreased. CONCLUSIONS: LUS could be a sensitive tool for ILD detection. CXR and LUS have different but complementary features, and their combined use could reduce the need for HRCT. The use of different diagnostic criteria for defining ILD does not affect sensitivity but influences specificity.

Implications and issues related to familial pancreatic cancer: a cohort study of hospitalized patients.

BACKGROUND: The surveillance of subjects at risk of pancreatic cancer is restricted to clinical research; the incidence of familial pancreatic cancer needs to be better established. Thus, we aimed to evaluate the frequency of familial pancreatic cancer in a population of hospitalized patients with pancreatic cancer. METHODS: A retrospective study based on the hospital charts of patients discharged with a diagnosis of pancreatic cancer. One hundred and eighty-seven patients or their relatives were called for a phone interview. RESULTS: There were 97 males (51.9 %) and 90 (48.1 %) females. The overall mean ± SD age was 67.3 ± 11.8 years; the age of males was similar to that of females (P = 0140). The mean size of the tumors found was 36.3 ± 17.4 mm (range of 5-110 mm); it was related to gender but was not related to the site of the tumor or the age of the patient. Regarding genetic diseases, three females (1.6 %) had familial adenomatous polyposis; three patients (1 male and two females) (1.6 %) had at least one relative with pancreatic cancer whereas only one 80-year old male patient (0.5 %) had two relatives affected by pancreatic cancer (the mother had died at the 65 years of age and the brother had died at 75 years of age). CONCLUSIONS: The frequency of familial pancreatic ductal adenocarcinoma is small, but its importance, from the point of view of early diagnosis, is not negligible and patients with a risk of familial cancer merit an appropriate clinical follow-up.

Incidental finding of bronchial diverticula in a non-smoker population: evaluation on thin-section CT.

Bronchial diverticula have been described as a common radiological finding in smoker patients with COPD, but the specificity of this sign should be further investigated. Thus, the aim of our study was to evaluate the prevalence of diverticula in a cohort of non-smoker subjects. Between February and July 2012, 2438 patients were admitted to our Radiology Unit to undergo a chest CT. Among them, we enrolled 121 non-smoking patients (78/121-64.5% females, 43/121-35.5% males), of different age (57.0±20.7 years-range: 12-88), without any respiratory symptoms, submitted to chest CT for several reasons (oncologic evaluation: 59/121-48.8%; follow up of lung nodules: 27/121-22.3%; screening in connectivitis: 12/121-9.9%; others: 23/121-19.0%). We considered thin-section CT scan on axial, coronal and sagittal plans to evaluate prevalence, numbers and level of bronchial diverticula. Diverticula were found in 41/121-33.9% patients, with a slight major prevalence in males (p=0.048), but no significant difference on age. In 31/41-75.6% the number was <3, whereof 17/31-54.8% with just one diverticulum assessed. Regarding the level, in 30/41-73.2% they were subcarinal, but they were also detected in mainstem (2/41-4.9%) and lobar bronchi (with the right upper lobe bronchus most frequently involved- 12/41-29.3%). Bronchial diverticula can be observed in non-smokers, as well as in smoker patients with COPD. However, their prevalence seems to be lower than in smokers and they tend to be isolated and subcarinal. The age of patients does not influence their finding. More studies should be proposed to better define a cut-off between smokers and healthy subjects.

The Senile Lung as a Possible Source of Pitfalls on Chest Ultrasonography and Computed Tomography.

BACKGROUND: Age-associated changes in the pulmonary system could be detected with imaging techniques. Widespread use of lung ultrasonography (US) requires characterization of a normal pattern. OBJECTIVES: To compare US and computed tomography (CT) findings in healthy subjects undergoing both techniques (with CT as the gold standard). METHODS: We prospectively selected 59 subjects undergoing chest CT and US on the same day, without a history of smoking, respiratory symptoms, or known pulmonary pathologies. There were 44 patients in group 1 (age ≥60 years - elderly) and 15 patients in group 2 (age ≤50 years - young). Lung US was performed with a convex and a linear probe, and 10 chest areas per patient were analyzed. Convex and linear probe agreement was evaluated by means of the Cohen κ statistic; Fisher's exact test was used to compare categorical variables between groups. RESULTS: Isolated B-lines were frequent in both group 1 (54.5%) and group 2 (40.0%); the number of chest areas positive for B-lines increased with age (16.1% in group 1 vs. 5.3% in group 2, p = 0.0028). In group 2, we found that 37.5% of subjects with B-lines had at least 1 chest area with multiple B-lines, but only 2 subjects had 2 or more. Moreover, in group 1 the chest CT documented a reticular pattern (2.3%), areas of increased density (9.1%), ground glass (6.8%), cysts (2.3%), bronchiectasis (22.7%), and bronchial thickening (6.8%); in group 2, only cysts (6.7%) and bronchiectasis (6.7%) were found. CONCLUSIONS: The senile lung is characterized by mild changes on CT and US. Chest areas positive for B-lines increase with age, and focal multiple B-lines can be found. However, diffuse patterns, especially in symptomatic subjects, suggest a different diagnosis.

Sonography of the normal lung: Comparison between young and elderly subjects.

BACKGROUND: The senile lung undergoes physiologic changes that are well known but have not been investigated with ultrasound (US). Thus, the aim of our study was to compare the US appearances of the lungs in a group of healthy, nonsmoker elderly subjects with those in a group of young subjects. METHODS: One hundred elderly subjects older than 65 years of age (mean age ± SD, 79 ± 7 years) and 50 younger subjects less than 56 years of age (mean age ± SD, 33 ± 12) underwent US examination of the lungs. We analyzed the anterior, midlateral, and posterobasal surface of each lung to evaluate the presence or absence of A-lines and B-lines. Fisher's exact test and Pearson's χ2 test were used to compare the findings in the two groups. RESULTS: A-lines were absent in 94/100 (94%) elderly subjects versus 2/50 (4%) young subjects (p < 0.0001). B-lines were found in 37/100 (37%) elderly subjects: ≤3 lines per field of view in 27/37 (73%); >3 lines in 2/37 (5%); both ≤3 lines and >3 lines (depending on the region scanned) in 8/37 (22%). In contrast, only in 5/50 (10%) young subjects were B-lines visible (≤3 lines per field of view in all cases [p < 0.001]). CONCLUSIONS: The majority of the elderly subjects did not have A-lines, and B-lines were observed in a high percentage. The reduction of impedance between lung parenchyma and soft tissues of the chest wall and the increased thickness of interlobular septa might explain these results. © 2014 Wiley Periodicals, Inc.

"Health for All" in England and Brazil?

This article discusses the achievements and challenges that England and Brazil face in relation to their capacity to address inequalities in health through health promotion and public health policies. Using secondary data (policy texts and related documents), this article contextualizes, explains, and critically appraises health promotion and public health efforts for the reduction of inequalities in health in the 2 countries. A historic documentary analysis was undertaken, with hermeneutics as the methodological framework. The global economic crisis has prompted the so-called developed economies of Europe to reconsider their economic and social priorities. England represents a state facing this kind of challenge. Equally, Brazil is assuming new positions not only on the world stage but also in terms of the relationship it has with its citizens and the priorities it has for state welfare. The United Kingdom continues to finance a health care system allowing universal access in the form of the National Health Service, and state concern about the public health task of reducing inequalities has recently been underlined in policy. For Brazil, although there have been recent achievements related to population access to healthcare, challenges continue, especially with regard to the quality of care.

[Child care and health rights: perspectives of adolescent mothers]. / O cuidado da criança e o direito à saúde: perspectivas de mães adolescents.

OBJECTIVE: To analyze child health care and the defense of their rights from the perspective of adolescent mothers. METHODS: An exploratory study with qualitative thematic analysis of data, based on conceptual aspects of care and the right to health, from semi-structured interviews with 20 adolescent mothers ascribed by Family Health teams. RESULTS: Maternal reports indicate that child health care requires responsibility and protection, with health practices that promote child advocacy. Gaps in assistance which preclude the full guarantee of the right to child health care were also highlighted. CONCLUSION: The right to health care assumed different meanings, and the forms to guarantee them were linked to individual behavior in detriment to broader actions that consider health as a social product, connected to the guarantee of other fundamental rights.

[Vulnerability of children in adverse situations to their development: proposed analytical matrix]. / Vulnerabilidade da criança diante de situações adversas ao seu desenvolvimento: proposta de matriz analítica.

This theoretical study presents a conceptual matrix built to analyze the vulnerability of children in adverse situations to their development. It proposes that the vulnerability of children is analyzed by means of the following dimensions: individual , which is related to ongoing nurturing relationships, physical protection and security; social , which concerns the social insertion of family and access to rights of social protection and promotion; and programmatic , which involves the political-programmatic scenario and the guidelines and political-programmatic implementation. The practical application of this matrix allows apprehending the health-disease process beyond the individual dimension, enabling the articulation of public policies and actions of professionals to achieve effectiveness in meeting the needs of children. The use of this conceptual matrix can provide to health teams a specific understanding of the adverse situations to child development as well as subsidizing intervention plans based on the analytical dimensions of vulnerability.

Primary Soft-Tissue Lymphomas: MRI Features Help Discriminate From Other Soft-Tissue Tumors.

OBJECTIVES: MRI presentation of extra-nodal soft-tissue lymphomas (STLs) is scarcely reported and lacks of comparison with other soft-tissue tumors (STTs) including sarcomas (STS). Yet, suggesting this diagnosis on MRI would considerably reduce diagnostic intervals. Our aim was to investigate if conventional MRI could discriminate STLs from other STTs. METHODS: MRIs of STL patients were compared with those of patients addressed to a sarcoma reference center for the diagnosis of a STT. MRI characteristics depicting the tumor (size, signal, habitats, shape, surrounding tissues) were reported. Uni- and multivariate associations with STL diagnosis were evaluated in the entire cohort, and in the subgroups of benign and malignant STTs patients. Diagnostic performances of MRI features combinations were tested. RESULTS: We included 39 patients with STLs (median age: 69 years) and 368 patients with other STTs (122 benign STTs and 246 STS; median age: 58 years). Six MRI features were independent predictors of STL compared to all other STTs: intermediate SI on T1-WI, homogeneous enhancement (without necrotic areas), no blood signal, no fibrotic signal, no peritumoral enhancement and lack of abnormal intra- and peritumoral vasculature (p-value range: <0.0001-0.0163). Their simultaneous presence had a sensitivity of 0.88 (0.71-0.96) and a specificity of 0.88 (0.84-0.91). Other relevant MRI features were: no fat signal to discriminate against STS (p = 0.0409), the infiltrative growth pattern and the vessel and nerve encasement to discriminate against benign STTs (p = 0.0016 and 0.0011, respectively). CONCLUSION: Our research demonstrates that conventional MRI can help discriminating STLs from other STTs. Indeed, radiologists can help suggesting the possible diagnosis of STL, which could speed-up the subsequent proper histopathological analysis in light of MRI findings.

Inattention symptoms in early pregnancy predict parenting skills and infant maltreatment during the first year of life.

OBJECTIVE: Maternal attention-deficit/hyperactivity disorder has not been investigated in relation to parenting skills in adolescent mothers. This study investigated whether maternal inattention and hyperactivity/impulsivity symptoms early in pregnancy predict poorer parenting skills and infant maltreatment during the first year of life in adolescent mothers living in adverse environmental conditions. METHODS: The participants in this study were 80 adolescent mothers aged 14-19 years and their babies who were taking part in a randomized controlled trial on the effects of a home-visiting program on infant development. Symptoms of maternal attention-deficit/hyperactivity disorder were assessed in the first trimester of pregnancy. Parenting skills (maternal competence, attachment to the baby, home environment) and child maltreatment were assessed when the infants were aged 6 and 12 months. Multilevel linear regression models were constructed to test the extent to which prenatal maternal inattention and hyperactivity/impulsivity symptoms predicted these parenting variables during the first year of the infant's life. RESULTS: Prenatal inattention symptoms significantly predicted lower maternal competence and attachment, a poorer home environment, and greater maltreatment during the first year of life. Hyperactivity did not significantly predict parenting skills or maltreatment. CONCLUSIONS: Our findings suggest that inattention symptoms may interfere with parenting abilities in adolescent mothers and should be considered in early intervention programs.

Pyogenic and Non-pyogenic Spinal Infections: Diagnosis and Treatment.

Spinal Infection (SI) is an infection of vertebral bodies, intervening disc, and/or adjoining para-spinal tissue. It represents less than 10% of all skeletal infections. There are numerous factors that predispose to developing a SI. Due to the low specificity of signs, delayed diagnosis is common. Hence, SI may be associated with poor outcomes. Diagnosis of SI must be supported by clinicopathological and radiological findings. MRI is a reliable modality of choice. Treatment options vary according to the site of the infection, disease progression, neurology, presence of instability, and general condition of the subject. Conservative treatment (orthosis/ bed-rest + antibiotics) is recommended during the early course with no/ lesser degree of neurological involvement and to medically unfit patients. Nevertheless, when conservative measures alone fail, surgical interventions must be considered. The use of concomitant antimicrobial drugs intravenously during initial duration followed by oral administration is a necessity. Controversies exist regarding the optimal duration of antimicrobial therapy, yet never given less than six weeks. Heterogeneity in clinical picture and associated co-morbidities with a range of treatment modalities are available; however, a common applicable guideline for SI does not exist. Managing SI must be tailored on a case-to-case basis.

[Integrated management of childhood illness (IMCI) in the practice of nurses graduated from USP]. / Atenção integrada as doenças prevalentes na infância (AIDPI) na prática de enfermeiros egressos da USP.

This is a description of the Integrated Management of Childhood Illness (IMCI) strategy in the professional practice of nurses graduated from the School of Nursing of University of São Paulo (EE-USP). This is a case study of qualitative approach. The data were collected through focus groups and analyzed using thematic content analysis. IMCI strategy was considered an important tool in child health care, but only the assessment module was apart of professional practice. Difficulties in the use of the IMCI were: the strategy was not implanted at health services, it was unknown by co-workers and institutional obstacles. In spite of the limited and non-systematic use of IMCI, it has allowed nurses to provide integrated and comprehensive attention to the child, which justifies its teaching on undergraduate courses. Maintenance of the educational video, expansion of the practice, integration of courses and optimization of content and workload were suggested for improving the teaching of IMCI at the undergraduate level.

Possibilities of the WHOQOL-bref for health promotion in the family health strategy. / Possibilidades do WHOQOL-bref para a promoção da saúde na estratégia saúde da família.

By increasing the health promotion actions in the Family Health Strategy it is possible to contribute to implement comprehensive care. Nevertheless, technologies gap still hinder the process of training the professionals to analyze the health potentials of the population. The objective of this study is to synthesize the contributions of the WHOQOL-bref in training professionals regarding the health promotion actions in the Family Health Strategy. A qualitative meta-synthesis was performed based on the research conducted by the group Technological health care models and health promotion using the WHOQOL-bref and its interface with health promotion. The synyhesis of the five studies revealed that there are conceptual relationships between the WHOQOL-bref domains and health promotion, which legitimizes it as a tool for health promotion. Using the WHOQOL-bref can help establish the attachment and continuous care in the Family Health Strategy.

Radiologic Assessment of Osteosarcoma Lung Metastases: State of the Art and Recent Advances.

The lung is the most frequent site of osteosarcoma (OS) metastases, which are a critical point in defining a patient's prognosis. Chest computed tomography (CT) represents the gold standard for the detection of lung metastases even if its sensitivity widely ranges in the literature since lung localizations are often atypical. ESMO guidelines represent one of the major references for the follow-up program of OS patients. The development of new reconstruction techniques, such as the iterative method and the deep learning-based image reconstruction (DLIR), has led to a significant reduction of the radiation dose with the low-dose CT. The improvement of these techniques has great importance considering the young-onset of the disease and the strict chest surveillance during follow-up programs. The use of 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT is still controversial, while volume doubling time (VDT) and computer-aided diagnosis (CAD) systems are recent diagnostic tools that could support radiologists for lung nodules evaluation. Their use, well-established for other malignancies, needs to be further evaluated, focusing on OS patients.

Craniofacial Osteomas: From Diagnosis to Therapy.

An osteoma is a benign bone lesion with no clear pathogenesis, almost exclusive to the craniofacial area. Osteomas show very slow continuous growth, even in adulthood, unlike other bony lesions. Since these lesions are frequently asymptomatic, the diagnosis is usually made by plain radiography or by a computed tomography (CT) scan performed for other reasons. Rarely, the extensive growth could determine aesthetic or functional problems that vary according to different locations. Radiographically, osteomas appear as radiopaque lesions similar to bone cortex, and may determine bone expansion. Cone beam CT is the optimal imaging modality for assessing the relationship between osteomas and adjacent structures, and for surgical planning. The differential diagnosis includes several inflammatory and tumoral pathologies, but the typical craniofacial location may aid in the diagnosis. Due to the benign nature of osteomas, surgical treatment is limited to symptomatic lesions. Radical surgical resection is the gold standard therapy; it is based on a minimally invasive surgical approach with the aim of achieving an optimal cosmetic result. Reconstructive surgery for an osteoma is quite infrequent and reserved for patients with large central osteomas, such as big mandibular or maxillary lesions. In this regard, computer-assisted surgery guarantees better outcomes, providing the possibility of preoperative simulation of demolitive and reconstructive surgery.

A randomized controlled trial testing the efficacy of a Nurse Home Visiting Program for Pregnant Adolescents.

To test the efficacy of a nurse home visiting program (HVP) on child development, maternal and environmental outcomes in the first years of life. We conducted a randomized controlled trial to test the efficacy of Primeiros Laços, a nurse HVP for adolescent mothers living in a poor urban area of São Paulo, Brazil. Eighty adolescent mothers were included and randomized to receive either Primeiros Laços (intervention group, n = 40) or healthcare as usual (control group, n = 40). Primeiros Laços is a home visiting intervention delivered by trained nurses that starts during the first 16 weeks of pregnancy and continues to the child's age of 24 months. Participants were assessed by blind interviewers at 8-16 weeks of pregnancy (baseline), 30 weeks of pregnancy, and 3, 6, 12, and 24 months of child's age. We assessed oscillatory power in the mid-range alpha frequency via electroencephalography when the children were aged 6 months. Child development was measured by the Bayley Scales of Infant Development Third Edition (BSID-III). Weight and length were measured by trained professionals and anthropometric indexes were calculated. The home environment and maternal interaction with the child was measured by the Home Observation and Measurement of the Environment. Generalized estimating equation models were used to examine intervention effects on the trajectories of outcomes. Standardized effect sizes (Cohen's d) were calculated using marginal means from endpoint assessments of all outcomes. The trial was registered at clinicaltrial.gov: NCT02807818. Our analyses showed significant positive effects of the intervention on child expressive language development (coefficient = 0.89, 95% CI [0.18, 1.61], p = 0.014), maternal emotional/verbal responsivity (coefficient = 0.97, 95% CI [0.37, 1.58], p = 0.002), and opportunities for variety in daily stimulation (coefficient = 0.37, 95% CI [0.09, 0.66], p = 0.009). Standardized effect sizes of the intervention were small to moderate. Primeiros Laços is a promising intervention to promote child development and to improve the home environment of low-income adolescent mothers. However, considering the limitations of our study, future studies should be conducted to assess Primeiros Laços potential to benefit this population.Clinical Trial Registration: The study was registered at clinicaltrial.gov (Registration date: 21/06/2016 and Registration number: NCT02807818).
