We consider the problem where the data consist of a survival time and a binary outcome measurement for each individual, as well as corresponding predictors. The goal is to select the common set of predictors which affect both the responses, and not just only one of them. In addition, we develop a survival prediction model based on data integration. This article is motivated by the Cancer Genomic Atlas (TCGA) databank, which is currently the largest genomics and transcriptomics database. The data contain cancer survival information along with cancer stages for each patient. Furthermore, it contains Reverse-phase Protein Array (RPPA) measurements for each individual, which are the predictors associated with these responses. The biological motivation is to identify the major actionable proteins associated with both survival outcomes and cancer stages. We develop a Bayesian hierarchical model to jointly model the survival time and the classification of the cancer stages. Moreover, to deal with the high dimensionality of the RPPA measurements, we use a shrinkage prior to identify significant proteins. Simulations and TCGA data analysis show that the joint integrated modeling approach improves survival prediction.While hypotheses frame explanatory studies and provide guidance for measurement and statistical tests, deductive, exploratory research does not have a framing device like the hypothesis. To this purpose, this article examines the landscape of deductive, exploratory research and offers the working hypothesis as a flexible, useful framework that can guide and bring coherence across the steps in the research process. The working hypothesis conceptual framework is introduced, placed in a philosophical context, defined, and applied to public administration and comparative public policy. Doing so, this article explains the philosophical underpinning of exploratory, deductive research; how the working hypothesis informs the methodologies and evidence collection of deductive, explorative research; the nature of micro-conceptual frameworks for deductive exploratory research; and, how the working hypothesis informs data analysis when exploratory research is deductive.A 62-year-old female patient with systemic lupus erythematosus (SLE) was admitted for cerebral infarction. The magnetic resonance angiography showed focal narrowing of the cerebral arteries that was initially considered as atherosclerosis due to her cardiovascular risk factors. Ten weeks later, she was again admitted for multiple cerebral infarctions. Vessel wall magnetic resonance imaging revealed gadolinium enhancement of the arterial walls of the narrowing lesions, leading to a diagnosis of cerebral arteritis. Based on a literature review, cerebral medium-sized arteritis in SLE likely progresses insidiously during the active phase of SLE, which may later result in occlusion irrespective of disease activity.A 67-year-old man underwent posterior cervical decompression surgery for ossification of the posterior longitudinal ligament (OPLL) with fixation using cervical pedicle screws (CPSs) guided by intraoperative 3D image-based navigation. Intraoperatively, while creating the screw hole using the navigation probe, the virtual trajectory on the intraoperative navigation screen showed a 10-degree angle discrepancy in the axial plane depending on whether a probing force was or was not applied for making the hole. This was potentially caused by vertebra rotation and a bent probe. Consequently, the CPSs were placed more laterally than the ideal trajectory, which resulted in less then 2 mm lateral perforation to the foramen transversarium. There were no screw insertion-related perioperative complications. Based on this case, we conclude that navigation error during CPS insertion can occur even with intraoperative 3D image-based navigation. The risk of a bowed navigation probe caused by posterior cervical muscle and vertebra rotation should be considered, even with use of a navigation reference frame.Herein, we present a case of extramammary Paget's disease with brain metastasis that was diagnosed pathologically for the first time in Japan. Moreover, invasive extramammary Paget's disease (with distant metastasis) highly resistant to treatment. Only for brain metastasis, we may control the tumor by surgical resection and stereotactic radiosurgery (SRT) for the treatment of intracranial metastases was assessed. An 76-year-old man was diagnosed with extramammary Paget's disease of the vulva at nearby hospital. Surgical resection and sentinel lymph node dissection were then performed, and the patient received chemotherapy because multiple lymph node metastases were suspected. The patient's response to chemotherapy was poor, and he was in the state of Progressive Disease. He complained of dyslexia and was referred to another hospital when he was 81 years old. Plain magnetic resonance imaging (MRI) was conducted, and two brain tumors in the vicinity of the left cerebellar tent were suspected. In our hospital, gadolinium contrast-enhanced MRI was performed and showed a tumor in the cerebellum (left posterior temporal lobe) and another tumor under the tent (left cerebellar hemisphere). Significant edema was also noted. Based on these findings, the intracranial lesion was diagnosed as metastatic brain tumor. The pathological diagnosis was brain metastasis from extramammary Paget's disease. Postoperative intracranial residual disease was treated with stereotactic radiosurgery. MRI showed that the size of the cerebellar lesions decreased, and no recurrence of cerebral lesions was observed. SRT for extracranial lymph node metastases was performed. CUDC-101 clinical trial Mass reduction and SRT may be the best way to treat brain metastasis from extramammary Paget's disease.Quantitative Fluorescent - Polymerase Chain Reaction (QF-PCR) is a rapid prenatal diagnosis test for 21, 18, 13 and sex chromosomal aneuploidy detection. However, it could not detect partial trisomy or partial monosomy of those chromosomes. Here, we report a 19-month-old Vietnamese female with a 9.9 Mb pure deletion of chromosome 18 at 18p11.32-11.22 confirmed by next generation sequencing. The patient was short statured with facial dysmorphic features as well as motor skill and speech delays. First trimester screening showed high risk of trisomy 21 with only increased nuchal translucency (NT 3.9 mm) by ultrasound as an indication. Prenatal diagnosis by QF-PCR from amniotic DNA revealed normal disomy. Noticeably, two short tandem repeat (STR) markers D18S391 and D18S976 located on 18p exhibited uninformative patterns (one peak). Thus, our case suggested that the combination of both D18S391 and D18S976 markers with uninformative patterns in QF-PCR for prenatal diagnosis and increased NT in the first trimester ultrasound may be a significant indication of 18p monosomy.
