The Role of Childhood Violence in Adult Victimization Among Women Experiencing Homelessness in Spain.

Persons experiencing homelessness represent one of the principal manifestations of the phenomenon of social exclusion, with homeless women constituting a group in a particularly vulnerable situation. The article analyzed the experience of violence in childhood and adolescence, and its implications in terms of violence experienced as an adult, in a sample of women experiencing homelessness in Madrid (Spain) (n = 138). All participants were of legal age and had spent the night before the interview in a shelter or other facility for the homeless, on the street, in public spaces or in places not suitable for sleeping. Information was gathered through a structured interview. The results show that the interviewees had experienced a high percentage of physical, psychological, and/or sexual violence, both in their childhood and adolescence and throughout their lives, with a strong correlation between the experience of violence in childhood and the experience of violence in adulthood, particularly sexual assaults, intimate partner violence, and sex work. The experience of childhood sexual abuse among women experiencing homelessness appears to have had particularly negative consequences in adulthood. Public policies, prevention programs, and care mechanisms with a gendered perspective must be implemented, aimed at reducing the number and intensity of situations of violence experienced by women and girls at risk of social exclusion or in a homeless situation.

Determining factors in the overall happiness and outlook for the future of women living homeless: Evidence from Madrid, Spain.

People living homeless are quite heterogeneous groups, including different subgroups with specific characteristics that vary substantially. Within this group, women living homeless are an understudied subgroup with specific necessities which in most cases have not been addressed in general studies related to the group. The present study examines determining factors that influence the levels of overall happiness and outlook for the future of women living homeless. To fulfill this objective, a survey was conducted on a group of women living homeless in the city of Madrid (Spain). The results of a structural equation modeling analysis found that having a larger and stable social support network, loneliness, and good health conditions without any problems associated with drug abuse are the main factors influencing their levels of overall happiness and their outlook for the future. The proposed model has also shown that stressful life events play an important role in the analysis, unlike economic aspects, which have a limited impact on their situation. This article provides new information and innovation in research about homelessness, in particular women living homeless, thus being important for extending and replicating its findings to an international context.

Health situation and perceived health status among women experiencing homelessness: A longitudinal study in Spain.

The paper analyses the health situation and the perceived health status of a sample of women experiencing homelessness (n = 138) in Madrid, Spain. All participants were adults, and the night before the baseline interview, they had slept on the street, at a shelter or any facility provided to care for people living homeless. The information was collected using structured interviews, repeated twice a year for a 3-year follow-up period. The findings of this study show that women experiencing homelessness presented poor health, particularly in comparison with the general Spanish population. Over half of the women questioned claimed to have a diagnosed serious or chronic illness, with a correlation between these conditions and the age, time spent homeless or high levels of drug use. There was a positive correlation found between women's perceived health status and being younger and having access to independent accommodation, while having suffered a number of stressful life events and having spent long periods of time living homeless presented a negative correlation with a good perceived health status.

Access to employment and the labor market among women living homeless in Madrid, Spain.

BACKGROUND: People living homeless represent one of the most extreme embodiments of the phenomena of poverty and social exclusion, and women are a particularly vulnerable group among people living homeless. METHODS: Various factors in a sample of women living homeless in Madrid, Spain (n = 136) have been analyzed for relationships to connections to the employment and labor market. Information was collected using a structured interview. RESULTS: Results show the considerable difficulties women living homeless have in accessing the employment and labor market, despite largely having worked throughout their lives, mainly in unstable jobs, in the informal sector or in related marginal activities. In general, women living homeless tended to attribute their difficulties in accessing the labor market to personal characteristics, dispositional factors, or situational factors beyond their control. A large number of interviewees wanted to work, although few of them did so. Interviewees who reported that they were seeking employment were primarily younger women, in better health, who had been unemployed for a short time, had spent less time homeless, and were of foreign origin.

Evolution of the accommodation situation among women living homeless in Madrid, Spain: A longitudinal study.

Women constitute a particularly vulnerable subgroup of people living homeless, with their own set of circumstances and life histories that are different from men in the same situation. In this paper, we present the results of a longitudinal study on the situation, needs, characteristics, and process of change among women in a homeless situation in Madrid (Spain). This study involved 136 homeless women who were spending the night at shelters, drop-in centers, on the street, or in public spaces. Data was collected through structured interviews conducted every 6 months for a total of 3 years. Throughout that period of time approximately half of the interviewed leaves the most extreme situation of homelessness. One in four interviewees gained access to independent accommodation, although in most cases this did not mean that they were no longer in a position of residential exclusion. The logistic regression analyses performed suggested that the variables with the closest correlation to improved accommodation were: receiving stable government economic benefits, obtaining income from work, not having Spanish nationality, not having a disability and having suffered fewer stressful life events at baseline, as well as a better perceived state of health. However, with regard to access to independent accommodation, the most closely-related variables were receiving stable government economic benefits and obtaining an income from work.

Jacobsen Syndrome: Surgical Complications due to Unsuspected Diagnosis, the Importance of Molecular Studies in Patients with Craniosynostosis.

Jacobsen syndrome (JBS) is an uncommon contiguous gene syndrome. About 85-92% of cases have a de novo origin. Clinical variability and severity probably depend on the size of the affected region. The typical clinical features in JBS include intellectual disability, growth retardation, craniofacial dysmorphism as well as craniosynostosis, congenital heart disease, and platelet abnormalities. The proband was a 1 year/3-month-old Mexican male. Oligonucleotide-SNP array analysis using the GeneChip Human Cytoscan HD was carried out for the patient from genomic DNA. The SNP array showed a 14.2-Mb deletion in chromosome 11q23.3q25 (120,706-134,938 Mb), which involved 163 RefSeq genes in the database of genomic variation. We report a novel deletion in JBS that increases the knowledge of the variability in the mutation sites in this region and expands the spectrum of molecular and clinical defects in this syndrome.

A Novel 23.1 Mb Interstitial Deletion Involving 7q22.3q32.1 in a Girl with Short Stature, Motor Delay, and Craniofacial Dysmorphism.

Interstitial deletions of 7q show a wide phenotypic spectrum that varies with respect to the location and size of the deleted region. They lead to craniofacial dysmorphism with intellectual disability, growth retardation, and various congenital defects. Here, a Mexican girl with microcephaly, facial dysmorphism, short stature, hand anomalies, and intellectual disability was analyzed by CytoScan HD array. Her phenotype was associated with a de novo 7q22.3q32.1 deletion involving 109 loci, 57 of them listed in the OMIM database. This novel deletion increases the knowledge of the variability in the rupture sites of the region and expands the spectrum of molecular and clinical defects of the 7q deletion syndrome.

Mucormycosis in a Non-Hodgkin Lymphoma Patient Caused by Syncephalastrum racemosum: Case Report and Review of Literature.

Mucormycosis is a rare opportunistic fungal infection caused by saprophytic zygomycetes. These fungal infections are caused by members of the mucorales. The clinical importance of zygomycosis, an emerging and frequently fatal mycotic disease, has increased during recent years, due to several risk factors such as (a) the use of broad-spectrum antibiotic, (b) use of empirical antifungal treatment (mainly triazoles), and (c) aggressive chemotherapy and sustained leucopenia (i.e., peripheral stem cell transplantation). An almost fulminant pneumonia caused by Syncephalastrum racemosum in an immunocompromised patient with an aggressive non-Hodgkin lymphoma (NHL) is described. Despite treatment with amphotericin B, deoxycholate, caspofungin, and surgical resection of fungal bodies from both lungs, and survival of 10 months without relapsing from fungal infection, the patient died due to hematological complications from an unresponsive disease. Herein is the description of the first case of pulmonary infection caused by Syncephalastrum racemosum.

Characterization of a Complex Chromosomal Rearrangement Involving a de novo Duplication of 9p and 9q and a Deletion of 9q.

Rearrangements of the distal region of 9p are important chromosome imbalances in human beings. Trisomy 9p is the fourth most frequent chromosome anomaly and is a clinically recognizable syndrome. Kleefstra syndrome, previously named 9q subtelomeric deletion syndrome, is either caused by a submicroscopic deletion in 9q34.3 or an intragenic mutation of EHMT1. We report a Mexican male patient with abnormal development, dysmorphism, systemic anomalies and a complex chromosomal rearrangement (CCR). GTG-banding revealed a 46,XY,add(9)(q34.3) karyotype, whereas array analysis resulted in arr[hg19] 9p24.3p23(203,861-11,842,172)×3, 9q34.3(138,959,881-139,753,294)×3, 9q34.3(139,784,913-141,020,389)×1. Array and karyotype analyses were normal in both parents. Partial duplication of 9p is one of the most commonly detected autosomal structural abnormalities in liveborn infants. A microdeletion in 9q34.3 corresponds to Kleefstra syndrome, whereas a microduplication in 9q34.3 shows a great clinical variability. Here, we present a CCR in a patient with multiple congenital anomalies who represents the first case with partial 9p trisomy, partial 9q trisomy and partial 9q monosomy.

A novel microdeletion involving the 13q31.3-q32.1 region in a patient with normal intelligence.

Microdeletions of the long arm of chromosome 13 lead to a characteristic facial appearance with systemic affection; 13q deletion shows a wide phenotypic spectrum that varies with respect to the location and size of the deletion region. The main clinical features are mental retardation, growth retardation, craniofacial dysmorphy and various congenital defects. In the present study we describe the case of an adult female of Mexican origin with microcephaly, facial dysmorphism, short stature, hand anomalies and normal intelligence associated with a de novo 13q31.3-q32.1 microdeletion that involved several genes including the MIR17HG and the GPC5 genes.

Folate, homocysteine, interleukin-6, and tumor necrosis factor alfa levels, but not the methylenetetrahydrofolate reductase C677T polymorphism, are risk factors for schizophrenia.

The methylenetetrahydrofolate reductase (MTHFR) C677T mutation has been associated to high homocysteine levels and schizophrenia. Since cytokines are altered in schizophrenia and increments of homocysteine could promote an inflammatory response, it was investigated whether interleukin-6 (IL-6) and tumor necrosis factor alfa (TNFalpha) levels are modulated by the MTHFR genotype. Serum levels of TNFalpha, IL-6, B(12), homocysteine, folate and red blood cell (RBC) folate as well as the MTHFR genotype were determined in a group of schizophrenic patients and compared to those of a control group. RBC folate levels were reduced and homocysteine and the two cytokines' concentrations were elevated in all patients as compared to controls. RBC folate in both heterozygous (CT) and homozygous (TT) patients was significantly different to that of their respective control groups. Homocysteine levels found in patients were significantly higher than those found in controls, only in individuals carrying the TT genotype. Cytokine levels were augmented in the group of patients irrespective of the genotype, and significant differences were found in all cases, except for TNFalpha levels in those subjects carrying the CC genotype. After adjusting for sex, low levels of RBC folate, high levels of homocysteine, both medium and high levels of TNFalpha and high IL-6 levels were associated with schizophrenia. MTHFR genotype was not a risk factor for developing the disease, although a larger sample is required to confirm this finding.

Functional analysis of myelodysplastic syndromes-derived mesenchymal stem cells.

Two different reports, including one from our own group, have recently demonstrated the presence of severe chromosomal abnormalities in mesenchymal stem cells (MSC) from patients with myelodysplastic syndromes (MDS). In the present study, we have assessed whether such cytogenetic abnormalities result in functional deficiencies in vitro. We found that both normal and MDS MSC showed similar expression patterns of cell adhesion molecules and extracellular matrix proteins. MDS MSC layers showed the capability to differentiate towards adipocytes, chondrocytes and osteoblasts, and supported the growth of early umbilical cord blood progenitors in a co-culture system. Unstimulated MDS MSC secreted more IL-1beta and after treatment with TNFalpha, they secreted more SCF, as compared to their normal counterparts. The present study demonstrates that, in spite of harboring severe chromosomal alterations, most of the functional properties of MDS-derived MSC remain normal, including their ability to support normal hematopoiesis in vitro.

Mesenchymal stem cells in myelodysplastic syndromes: phenotypic and cytogenetic characterization.

Bone marrow-derived mesenchymal stem cells (MSC) have been defined as primitive, undifferentiated cells, capable of self-renewal and with the ability to give rise to different cell lineages, including adipocytes, osteocytes, fibroblasts, chondrocytes, and myoblasts. MSC are key components of the hematopoietic microenvironment. Several studies, including some from our own group, suggest that important quantitative and functional alterations are present in the stroma of patients with myelodysplasia (MDS). However, in most of such studies the stroma has been analyzed as a complex network of different cell types and molecules, thus it has been difficult to identify and characterize the cell(s) type(s) that is (are) altered in MDS. In the present study, we have focused on the biological characterization of MSC from MDS. As a first approach, we have quantified their numbers in bone marrow, and have worked on their phenotypic (morphology and immunophenotype) and cytogenetic properties. MSC were obtained by a negative selection procedure and cultured in a MSC liquid culture medium. In terms of morphology, as well as the expression of certain cell markers, no differences were observed between MSC from MDS patients and those derived from normal marrow. In both cases, MSC expressed CD29, CD90, CD105 and Prolyl-4-hydroxylase; in contrast, they did not express CD14, CD34, CD68, or alkaline phosphatase. Interestingly, in five out of nine MDS patients, MSC developed in culture showed cytogenetic abnormalities, usually involving the loss of chromosomal material. All those five cases also showed cytogenetic abnormalities in their hematopoietic cells. Interestingly, in some cases there was a complete lack of overlap between the karyotypes of hematopoietic cells and MSC. To the best of our knowledge, the present study is the first in which a pure population of MSC from MDS patients is analyzed in terms of their whole karyotype and demonstrates that in a significant proportion of patients, MSC are cytogenetically abnormal. Although the reason of this is still unclear, such alterations may have an impact on the physiology of these cells. Further studies are needed to assess the functional integrity of MDS-derived MSC.
