Causes of Death Accompanying by Soft Tissue Neck Hemorrhage

Background: Generally, soft tissue hemorrhages in anterior part of the neck are attributed to the neck compression or trauma and suspicion goes more to homicidal death than suicide. Although artificial posterior neck hemorrhages are described as Prinsloo-Gordon phenomenon in cadavers with posterior lividity, studies conducted on such hemorrhages in the anterior and lateral compartments are rare. This study intends to investigate causes of death accompanied by soft tissue neck hemorrhages in different compartments of neck. Method: In this retrospective case series, between March 2008 and 2009, cadavers whose autopsies indicated soft tissue neck hemorrhages and the lividity was dominant in posterior, were evaluated according to the cause of death and anatomical and histological locations of hemorrhage. Results: Among 86 cases of neck hemorrhage, 72.1% (n=62) were male. Direct neck trauma, hanging, strangulation, chocking and positional asphyxia constituted 50% (n=43) of them, 40.7% (n=35) were non-asphyxial, non-traumatic deaths such as natural diseases, drug and CO poisoning, electrocution and drowning, and 9.3% (n=8) were unknown. 65.1% (n=28) of non-traumatic, non-asphyxial cases bore anterior or lateral neck hemorrhages. Conclusion: The considerable prevalence of soft neck tissue hemorrhages in non asphyxial deaths with no history of neck trauma and the location of such hemorrhages in anterior and lateral sides of neck, lead the investigators to pay more attention to interpret these hemorrhages and determining the mode and cause of death

Towards Long-term and Archivable Reproducibility

Analysis pipelines commonly use high-level technologies that are popular when created, but are unlikely to be readable, executable, or sustainable in the long term. A set of criteria is introduced to address this problem: Completeness (no execution requirement beyond a minimal Unix-like operating system, no administrator privileges, no network connection, and storage primarily in plain text); modular design; minimal complexity; scalability; verifiable inputs and outputs; version control; linking analysis with narrative; and free software. As a proof of concept, we introduce "Maneage" (Managing data lineage), enabling cheap archiving, provenance extraction, and peer verification that been tested in several research publications. We show that longevity is a realistic requirement that does not sacrifice immediate or short-term reproducibility. The caveats (with proposed solutions) are then discussed and we conclude with the benefits for the various stakeholders. This paper is itself written with Maneage (project commit eeff5de).Comment: The downloadable source (on arXiv) includes the full/automatic reproduction info (scripts, config files and input data links).

Association of TNF-α G308A gene polymorphism in essential hypertensive patients without type 2 diabetes mellitus

This study aims to investigate the effects of tumor necrosis factor alpha (TNF-α) G308A gene polymorphism on essential hypertension (EHT) with or without type 2 diabetes mellitus (T2DM). The project was conducted on buccal epithelial and blood cells for case and control patients, respectively. Epithelial cells were obtained from the inner part of the cheeks. Techniques including DNA extraction, polymerase chain reaction (PCR), and restriction fragment length polymorphism (RFLP) were utilized to assess biomarkers of DNA damage. Our results demonstrated significant differences between wild and mutated genotypes among EHT patients without T2DM. We also found a significant association between wild and mutated allele frequencies in EHT patients (P < 0.05). Clinical characteristics between the groups (EHT with or without T2DM and controls) showed statistically significant association (P < 0.05). Overall, we show that G308A polymorphism of the TNF-αgene may be a significant genetic risk factor for EHT without T2DM patients in Malaysia

Diagnosis of acute toxoplasmosis in pregnant women referred to therapeutic centers of Alborz Province (Iran) using immunoglobulin G avidity ELISA technique

Objective To evaluate immunoglobulin G (IgG) avidity as a useful and reliable technique in diagnosing toxoplasmosis in pregnant women referring to therapeutic centers of Alborz Province (Iran) in 2014, against two other tests, IgG and immunoglobulin G (IgM) anti-Toxoplasma. Methods Serum samples (468 in total) were obtained from different therapeutic centers in Karaj City. ELISA method was used to test the anti-Toxoplasma avidity of IgG, IgM and IgG. The data were analyzed by descriptive statistical methods and Chi-square test (P < 0.05) using SPSS 17.0. Results Anti-Toxoplasma avidity tests of IgM and IgG were positive in 9 and 86 samples respectively. Also, a borderline IgM avidity was detected in 2 suspected samples. In addition, among all positive and suspected samples, 79 cases indicated high titers of IgG avidity, 7 cases were of low titers and 1 case was of a borderline titer. The prevalence of anti-Toxoplasma antibodies was 20. The sera which showed high avidity index was obtained from patients at chronic phase of infection (77.7) while those which showed low avidity levels were from patients at acute toxoplasmosis (92). Conclusions This study clearly showed that acute and chronic phases of toxoplasmosis could be differentiated with the aid of IgG avidity test. This test may also assist in recognizing old and newly acquired infections. © 2016 Asian Pacific Tropical Medicine Pres

Individualised profiling of white matter organisation in moderate-to-severe traumatic brain injury patients

Background and purpose Approximately 65% of moderate-to-severe traumatic brain injury (m-sTBI) patients present with poor long-term behavioural outcomes, which can significantly impair activities of daily living. Numerous diffusion-weighted MRI studies have linked these poor outcomes to decreased white matter integrity of several commissural tracts, association fibres and projection fibres in the brain. However, most studies have focused on group-based analyses, which are unable to deal with the substantial between-patient heterogeneity in m-sTBI. As a result, there is increasing interest and need in conducting individualised neuroimaging analyses. Materials and methods Here, we generated a detailed subject-specific characterisation of microstructural organisation of white matter tracts in 5 chronic patients with m-sTBI (29 – 49y, 2 females), presented as a proof-of-concept. We developed an imaging analysis framework using fixel-based analysis and TractLearn to determine whether the values of fibre density of white matter tracts at the individual patient level deviate from the healthy control group (n = 12, 8F, Mage = 35.7y, age range 25 – 64y). Results Our individualised analysis revealed unique white matter profiles, confirming the heterogenous nature of m-sTBI and the need of individualised profiles to properly characterise the extent of injury. Future studies incorporating clinical data, as well as utilising larger reference samples and examining the test–retest reliability of the fixel-wise metrics are warranted. Conclusions Individualised profiles may assist clinicians in tracking recovery and planning personalised training programs for chronic m-sTBI patients, which is necessary to achieve optimal behavioural outcomes and improved quality of life

Comprehensive detection of recurring genomic abnormalities : a targeted sequencing approach for multiple myeloma

Recent genomic research efforts in multiple myeloma have revealed clinically relevant molecular subgroups beyond conventional cytogenetic classifications. Implementing these advances in clinical trial design and in routine patient care requires a new generation of molecular diagnostic tools. Here, we present a custom capture next-generation sequencing (NGS) panel designed to identify rearrangements involving the IGH locus, arm level, and focal copy number aberrations, as well as frequently mutated genes in multiple myeloma in a single assay. We sequenced 154 patients with plasma cell disorders and performed a head-to-head comparison with the results from conventional clinical assays, i.e., fluorescent in situ hybridization (FISH) and single-nucleotide polymorphism (SNP) microarray. Our custom capture NGS panel had high sensitivity (&gt;99%) and specificity (&gt;99%) for detection of IGH translocations and relevant chromosomal gains and losses in multiple myeloma. In addition, the assay was able to capture novel genomic markers associated with poor outcome such as bi-allelic events involving TP53. In summary, we show that a multiple myeloma designed custom capture NGS panel can detect IGH translocations and CNAs with very high concordance in relation to FISH and SNP microarrays and importantly captures the most relevant and recurrent somatic mutations in multiple myeloma rendering this approach highly suitable for clinical application in the modern era

Exploring personalized structural connectomics for moderate to severe traumatic brain injury

AbstractGraph theoretical analysis of the structural connectome has been employed successfully to characterize brain network alterations in patients with traumatic brain injury (TBI). However, heterogeneity in neuropathology is a well-known issue in the TBI population, such that group comparisons of patients against controls are confounded by within-group variability. Recently, novel single-subject profiling approaches have been developed to capture inter-patient heterogeneity. We present a personalized connectomics approach that examines structural brain alterations in five chronic patients with moderate to severe TBI who underwent anatomical and diffusion magnetic resonance imaging. We generated individualized profiles of lesion characteristics and network measures (including personalized graph metric GraphMe plots, and nodal and edge-based brain network alterations) and compared them against healthy reference cases (N = 12) to assess brain damage qualitatively and quantitatively at the individual level. Our findings revealed alterations of brain networks with high variability between patients. With validation and comparison to stratified, normative healthy control comparison cohorts, this approach could be used by clinicians to formulate a neuroscience-guided integrative rehabilitation program for TBI patients, and for designing personalized rehabilitation protocols based on their unique lesion load and connectome

Controlling a superconducting nanowire single-photon detector using tailored bright illumination

We experimentally demonstrate that a superconducting nanowire single-photon detector is deterministically controllable by bright illumination. We found that bright light can temporarily make a large fraction of the nanowire length normally-conductive, can extend deadtime after a normal photon detection, and can cause a hotspot formation during the deadtime with a highly nonlinear sensitivity. In result, although based on different physics, the superconducting detector turns out to be controllable by virtually the same techniques as avalanche photodiode detectors. As demonstrated earlier, when such detectors are used in a quantum key distribution system, this allows an eavesdropper to launch a detector control attack to capture the full secret key without being revealed by to many errors in the key.Comment: Expanded discussions, updated references. 9 pages, 8 figure
