Naming the Church: The Representation of Two Congregations in the Media
This study examines the portrayal of religious and ethnic group conflicts in the media using a case study in Oregon. Local newspaper reports about a struggle between the St. James Catholic Church and the San MartĂn Catholic Mission were analyzed using cluster criticism to identify the key terms used to communicate ideas about the two congregations to the local public. Various patterns of themes emerged, which indicate that the institutions and leaders on each side of the conflict were presented as opposing forces of hierarchy/community and logic/emotion. From this analysis it can be seen that the newspapers reporting on this conflict portrayed St. James as more of a hierarchical business structure, while San MartĂn was represented as a vulnerable and benevolent community. The newspaper\u27s rhetorical strategy of associating the names of the churches with certain features may have influenced local perceptions of the conflict, leading to a favorable outcome for the San MartĂn community.

Salva la Iglesia: A Congregation\u27s Fight for Community
The purpose of this study is to examine community response to crisis and the impact intercultural interactions have on the outcome of ethnic and religious group conflict. This research uses a case study focusing on the San MartĂn Catholic Mission in Oregon and the ways this particular community responded to the crisis of the Catholic diocese threatening to sell their property in 2010. I gathered data from a year of ethnographic fieldwork, participant observations in the setting, and in-depth interviews with six individuals involved in the church and related community groups. I then analyzed the data using the lens of social capital theory to examine the resource networks built through this event and their effect on the communities. Themes such as changing roles of immigrants and minorities in the United States, changing gender roles in community activism, and changing levels of activism after community crises are resolved emerged from this analysis, which indicate the importance of social factors in affecting community response to crisis. The findings of this case study have implications for how communities may need to adapt to the changing demographic of the United States as the Latino population increases, and it provides insight into patterns of interaction that may be seen between ethnic and religious communities in the future
Salva la Iglesia: Intercultural Capital and the Struggle for Community in a Small Town Congregation
The purpose of this study is to examine community response to crisis and the impact of intercultural interactions on the outcome of ethnic and religious group conflict. I seek to expand the traditional theoretical lens of forms of capital (Bourdieu, 1986) to include a new way of examining group interactions as they relate to intercultural capital. I use a case study focusing on the San MartĂn Catholic Mission in western Oregon and the ways this particular community responded to the crisis of the Catholic diocese threatening to sell their property in 2010. I gathered data from a year of ethnographic fieldwork, including participant observations in the setting and in-depth interviews with five individuals involved in the church and related community groups. I analyzed the data using the expanded lens of capital theory to examine the resource networks built through this event and their effect on the communities. Through my analysis, I identified the following themes: changing roles of immigrants and minorities in the United States, changing gender roles in community activism, and changing levels of activism after community crises are resolved. These themes indicate the importance of social factors in affecting community response to crisis. The findings of this case study have implications for how communities may need to adapt to the rising populations of Latino individuals and communities, and it provides insight into patterns of interaction between ethnic and religious communities in the future
Molecular genetics and pathophysiology of 17 beta-hydroxysteroid dehydrogenase 3 deficiency.
Autosomal recessive mutations in the 17 beta-hydroxysteroid dehydrogenase 3 gene impair the formation of testosterone in the fetal testis and give rise to genetic males with female external genitalia. Such individuals are usually raised as females, but virilize at the time of expected puberty as the result of increases in serum testosterone. Here we describe mutations in 12 additional subjects/families with this disorder. The 14 mutations characterized to date include 10 missense mutations, 3 splice junction abnormalities, and 1 small deletion that results in a frame shift. Three of these mutations have occurred in more than 1 family. Complementary DNAs incorporating 9 of the 10 missense mutations have been constructed and expressed in reporter cells; 8 of the 9 missense mutations cause almost complete loss of enzymatic activity. In 2 subjects with loss of function, missense mutations testosterone levels in testicular venous blood were very low. Considered together, these findings strongly suggest that the common mechanism for testosterone formation in postpubertal subjects with this disorder is the conversion of circulating androstenedione to testosterone by one or more of the unaffected 17 beta-hydroxysteroid dehydrogenase isoenzymes

Cancer Predisposition Cascade Screening for Hereditary Breast/Ovarian Cancer and Lynch Syndromes in Switzerland: Study Protocol
Background : Breast, colorectal, ovarian, and endometrial cancers constitute approximately 30% of newly diagnosed cancer cases in Switzerland, affecting more than 12,000 individuals annually. Hundreds of these patients are likely to carry germline pathogenic variants associated with hereditary breast ovarian cancer (HBOC) or Lynch syndrome (LS). Genetic services (counseling and testing) for hereditary susceptibility to cancer can prevent many cancer diagnoses and deaths through early identification and risk management. Objective : Cascade screening is the systematic identification and testing of relatives of a known mutation carrier. It determines whether asymptomatic relatives also carry the known variant, needing management options to reduce future harmful outcomes. Specific aims of the CASCADE study are to (1) survey index cases with HBOC or LS from clinic-based genetic testing records and determine their current cancer status and surveillance practices, needs for coordination of medical care, psychosocial needs, patient-provider and patient-family communication, quality of life, and willingness to serve as advocates for cancer genetic services to blood relatives, (2) survey first- and second-degree relatives and first-cousins identified from pedigrees or family history records of HBOC and LS index cases and determine their current cancer and mutation status, cancer surveillance practices, needs for coordination of medical care, barriers and facilitators to using cancer genetic services, psychosocial needs, patient-provider and patient-family communication, quality of life, and willingness to participate in a study designed to increase use of cancer genetic services, and (3) explore the influence of patient-provider communication about genetic cancer risk on patient-family communication and the acceptability of a family-based communication, coping, and decision support intervention with focus group(s) of mutation carriers and relatives. Methods: CASCADE is a longitudinal study using surveys (online or paper/pencil) and focus groups, designed to elicit factors that enhance cascade genetic testing for HBOC and LS in Switzerland. Repeated observations are the optimal way for assessing these outcomes. Focus groups will examine barriers in patient-provider and patient-family communication, and the acceptability of a family-based communication, coping, and decision-support intervention. The survey will be developed in English, translated into three languages (German, French, and Italian), and back-translated into English, except for scales with validated versions in these languages. Results: Descriptive analyses will include calculating means, standard deviations, frequencies, and percentages of variables and participant descriptors. Bivariate analyses (Pearson correlations, chi-square test for differences in proportions, and t test for differences in means) will assess associations between demographics and clinical characteristics. Regression analyses will incorporate generalized estimating equations for pairing index cases with their relatives and explore whether predictors are in direct, mediating, or moderating relationship to an outcome. Focus group data will be transcribed verbatim and analyzed for common themes. Conclusions: Robust evidence from basic science and descriptive population-based studies in Switzerland support the necessity of cascade screening for genetic predisposition to HBOC and LS. CASCADE is designed to address translation of this knowledge into public health interventions.

FDG-PET/CT imaging for staging and target volume delineation in conformal radiotherapy of anal carcinoma
Background: FDG-PET/CT imaging has an emerging role in staging and treatment planning of various tumor locations and a number of literature studies show that also the carcinoma of the anal canal may benefit from this diagnostic approach. We analyzed the potential impact of FDG-PET/CT in stage definition and target volume delineation of patients affected by carcinoma of the anal canal and candidates for curative radiotherapy.
Methods: Twenty seven patients with biopsy proven anal carcinoma were enrolled. Pathology was squamous cell
carcinoma in 20 cases, cloacogenic carcinoma in 3, adenocarcinoma in 2, and basal cell carcinoma in 2. Simulation was performed by PET/CT imaging with patient in treatment position. Gross Tumor Volume (GTV) and Clinical Target Volume (CTV) were drawn on CT and on PET/CT fused images. PET-GTV and PET-CTV were respectively compared to CT-GTV and CT-CTV by Wilcoxon rank test for paired data.
Results: PET/CT fused images led to change the stage in 5/27 cases (18.5%): 3 cases from N0 to N2 and 2 from
M0 to M1 leading to change the treatment intent from curative to palliative in a case. Based on PET/CT imaging, GTV and CTV contours changed in 15/27 (55.6%) and in 10/27 cases (37.0%) respectively. PET-GTV and PET-CTV resulted significantly smaller than CT-GTV (p = 1.2
7 10-4) and CT-CTV (p = 2.9
7 10-4). PET/CT-GTV and PET/CT-CTV, that were used for clinical purposes, were significantly greater than CT-GTV (p = 6
7 10-5) and CT-CTV (p = 6
7 10-5).
Conclusions: FDG-PET/CT has a potential relevant impact in staging and target volume delineation of the carcinoma of the anal canal. Clinical stage variation occurred in 18.5% of cases with change of treatment intent in 3.7%. The GTV and the CTV changed in shape and in size based on PET/CT imaging
Delineation and Diagnostic Criteria of Oral-Facial-Digital Syndrome Type VI
Oral-Facial-Digital Syndrome type VI (OFD VI) represents a rare phenotypic subtype of Joubert syndrome and related disorders (JSRD). In the original report polydactyly, oral findings, intellectual disability, and absence of the cerebellar vermis at post-mortem characterized the syndrome. Subsequently, the molar tooth sign (MTS) has been found in patients with OFD VI, prompting the inclusion of OFD VI in JSRD. We studied the clinical, neurodevelopmental, neuroimaging, and genetic findings in a cohort of 16 patients with OFD VI. We derived the following inclusion criteria from the literature: 1) MTS and one oral finding and polydactyly, or 2) MTS and more than one typical oral finding. The OFD VI neuroimaging pattern was found to be more severe than in other JSRD subgroups and includes severe hypoplasia of the cerebellar vermis, hypoplastic and dysplastic cerebellar hemispheres, marked enlargement of the posterior fossa, increased retrocerebellar collection of cerebrospinal fluid, abnormal brainstem, and frequently supratentorial abnormalities that occasionally include characteristic hypothalamic hamartomas. Additionally, two new JSRD neuroimaging findings (ascending superior cerebellar peduncles and fused thalami) have been identified. Tongue hamartomas, additional frenula, upper lip notch, and mesoaxial polydactyly are specific findings in OFD VI, while cleft lip/palate and other types of polydactyly of hands and feet are not specific. Involvement of other organs may include ocular findings, particularly colobomas. The majority of the patients have absent motor development and profound cognitive impairment. In OFD VI, normal cognitive functions are possible, but exceptional. Sequencing of known JSRD genes in most patients failed to detect pathogenetic mutations, therefore the genetic basis of OFD VI remains unknown. Compared with other JSRD subgroups, the neurological findings and impairment of motor development and cognitive functions in OFD VI are significantly worse, suggesting a correlation with the more severe neuroimaging findings. Based on the literature and this study we suggest as diagnostic criteria for OFD VI: MTS and one or more of the following: 1) tongue hamartoma(s) and/or additional frenula and/or upper lip notch; 2) mesoaxial polydactyly of one or more hands or feet; 3) hypothalamic hamartoma
Parallel sequencing of extrachromosomal circular DNAs and transcriptomes in single cancer cells
Extrachromosomal DNAs (ecDNAs) are common in cancer, but many questions about their origin, structural dynamics and impact on intratumor heterogeneity are still unresolved. Here we describe single-cell extrachromosomal circular DNA and transcriptome sequencing (scEC&T-seq), a method for parallel sequencing of circular DNAs and full-length mRNA from single cells. By applying scEC&T-seq to cancer cells, we describe intercellular differences in ecDNA content while investigating their structural heterogeneity and transcriptional impact. Oncogene-containing ecDNAs were clonally present in cancer cells and drove intercellular oncogene expression differences. In contrast, other small circular DNAs were exclusive to individual cells, indicating differences in their selection and propagation. Intercellular differences in ecDNA structure pointed to circular recombination as a mechanism of ecDNA evolution. These results demonstrate scEC&T-seq as an approach to systematically characterize both small and large circular DNA in cancer cells, which will facilitate the analysis of these DNA elements in cancer and beyond
Microenvironmentâinduced restoration of cohesive growth associated with focal activation of P âcadherin expression in lobular breast carcinoma metastatic to the colon
Invasive lobular carcinoma (ILC) is a special breast cancer type characterized by noncohesive growth and Eâcadherin loss. Focal activation of Pâcadherin expression in tumor cells that are deficient for Eâcadherin occurs in a subset of ILCs. Switching from an Eâcadherin deficient to Pâcadherin proficient status (EPS) partially restores cellâcell adhesion leading to the formation of cohesive tubular elements. It is unknown what conditions control EPS. Here, we report on EPS in ILC metastases in the large bowel. We reviewed endoscopic colon biopsies and colectomy specimens from a 52âyearâold female (index patient) and of 18 additional patients (reference series) diagnosed with metastatic ILC in the colon. EPS was assessed by immunohistochemistry for Eâcadherin and Pâcadherin. CDH1 /Eâcadherin mutations were determined by nextâgeneration sequencing. The index patient's colectomy showed transmural metastatic ILC harboring a CDH1 /Eâcadherin p.Q610* mutation. ILC cells displayed different growth patterns in different anatomic layers of the colon wall. In the tunica muscularis propria and the tela submucosa, ILC cells featured noncohesive growth and were Eâcadherinânegative and Pâcadherinânegative. However, ILC cells invading the mucosa formed cohesive tubular elements in the intercryptal stroma of the lamina propria mucosae. Interâcryptal ILC cells switched to a Pâcadherinâpositive phenotype in this microenvironmental niche. In the reference series, colon mucosa infiltration was evident in 13 of 18 patients, one of which showed intercryptal EPS and conversion to cohesive growth as described in the index patient. The large bowel is a common metastatic site in ILC. In endoscopic colon biopsies, the typical noncohesive growth of ILC may be concealed by microenvironmentâinduced EPS and conversion to cohesive growth
