Abstract
PURPOSE Direct oral anticoagulants (DOACs) have been approved, for over a decade, by both European and American medicine agencies, for treatment and prevention of several cardiovascular conditions. Since then, an increasing amount of data has been added to the medical literature day by day, resulting in a dichotomy in selection of the appropriate agent, dosage, and duration of treatment for special populations with multiple comorbidities. Considering these issues, we have prepared a comprehensive review for the clinical practitioner, to optimize the DOAC utilization in clinical practice. METHODS A thorough literature search and review was conducted, concerning mainly the last decade. Our review focused on the current guidelines and the most recently published studies in PubMed, Science Direct Scopus, and Google Scholar to date. CONCLUSION The purpose of this study is to provide guidance for healthcare professionals for making proper decisions when confronted with clinical challenges. Nevertheless, further research is required to establish DOAC superiority in complicated cases, where there is clinical uncertainty.

MEK inhibition enhances the antitumor effect of radiation therapy in NF1-deficient glioblastoma. Mol Cancer Ther 2024:745205. [PMID: 38714355 DOI: 10.1158/1535-7163.mct-23-0510] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Revised: 01/26/2024] [Accepted: 05/03/2024] [Indexed: 05/09/2024]
Abstract
Individuals with neurofibromatosis type 1 (NF-1), an autosomal dominant neurogenetic and tumor predisposition syndrome, are susceptible to developing low-grade glioma (LGG) and, less commonly, high-grade glioma (HGG). These gliomas exhibit loss of the neurofibromin gene (NF1), and 10-15% of sporadic HGG have somatic NF1 alterations. Loss of NF1 leads to hyperactive RAS signaling, creating opportunity given the established efficacy of MEK inhibitors (MEKi) in plexiform neurofibromas and some individuals with LGG. We observed that NF1-deficient glioblastoma neurospheres were sensitive to the combination of a MEKi (mirdametinib) with irradiation, as evidenced by synergistic inhibition of cell growth, colony formation, and increased cell death. In contrast, NF1-intact neurospheres were not sensitive to the combination, despite complete ERK pathway inhibition. No neurosphere lines exhibited enhanced sensitivity to temozolomide combined with mirdametinib. Mirdametinib decreased transcription of homologous recombination genes and RAD51 foci, associated with DNA damage repair, in sensitive models. Heterotopic xenograft models displayed synergistic growth inhibition to mirdametinib combined with irradiation in NF1-deficient glioma xenografts, but not those with intact NF1. In sensitive models, benefits were observed at least three weeks beyond the completion of treatment, including sustained phosphor-ERK inhibition on immunoblot and decreased Ki-67 expression. These observations demonstrate synergistic activity between mirdametinib and irradiation in NF1-deficient glioma models and may have clinical implications for patients with gliomas that harbor germline or somatic NF1 alterations.

The Immunohistochemical Expression of REV-7 in Various Human Cancer Pathology Specimens: A Systematic Review. Cureus 2024; 16:e52542. [PMID: 38371007 PMCID: PMC10874486 DOI: 10.7759/cureus.52542] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/18/2024] [Indexed: 02/20/2024] Open
Abstract
The purpose of this systematic review is to summarize all existing evidence, regarding the immunohistochemical expression of REV-7 in different human cancer pathology specimens. Moreover, the association of REV-7 expression with disease severity (clinical course), patients' survival, prognosis, and response to various treatments, such as chemotherapy and irradiation, was investigated. Three databases (PubMed, Scopus, and Cochrane) were systematically screened, from inception to September 2, 2023, as suggested by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Only studies using immunohistochemical staining for REV-7 in paraffin-embedded cancer tissues were included. Nine studies met the inclusion criteria and were included in the final qualitative synthesis. All nine studies were retrospective and non-comparative ones. Selected studies reported immunohistochemical expression of REV-7 in different types of cancer, including testicular cancer, ovarian cancer, esophagus squamous cell carcinoma, prostate cancer, colorectal cancer, diffuse large B-cell lymphoma, breast cancer, lung cancer, and skin cancer. High REV-7 expression was associated with faster disease progression, resistance to available treatment options, and worse prognosis in the majority of included studies. These results indicate that immunohistochemical staining of REV-7 protein could potentially be used as a predictive tissue marker in certain cases. Promising results, arising from REV-7 inactivation experiments, render REV-7 targeting a potential therapeutic strategy for future cancer management, especially in the cases of chemoresistant or radioresistant disease.

Microvessel Density (MVD) in Patients with Osteosarcoma: A Systematic Review and Meta-Analysis. Cancer Invest 2024; 42:104-114. [PMID: 38345052 DOI: 10.1080/07357907.2024.2311266] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2022] [Accepted: 01/24/2024] [Indexed: 02/21/2024]
Abstract
A meta-analysis was designed and conducted to estimate the effect of tumoral microvessel density (MVD) on the survival of patients with osteosarcoma. There was no difference between high and low MVD regarding the overall (OS) and disease-free (DFS) survival. Low MVD tumors displayed a lower DFS at the third year of follow-up. Although primary metastases did not affect the mean MVD measurements, tumors with a good chemotherapy response had a higher MVD value. Although no significant differences between tumoral MVD, OS and DFS were found, good adjuvant therapy responders had a significant higher vascularization pattern.

Colistin Effects on Emphysematous Lung in an LPS-Sepsis Model. Antibiotics (Basel) 2023; 12:1731.

Abstract
Emphysema is prevalent in various respiratory diseases like Chronic Obstructive Pulmonary Disease (COPD) and cystic fibrosis. Colistin and vasoconstrictive drugs are crucial for treating these patients when diagnosed with sepsis in the ICU. This study examines colistin impact in ether-induced emphysematous septic and non-septic animals, focusing on lung pathophysiology and inflammatory responses, including IL-1β, TNF-α, AMPK, caspase-3, cyclin-D1, and colistin levels in lung tissue. All animals exhibited significant emphysematous changes, accentuated by LPS-induced septic conditions, validating the emphysema model and highlighting the exacerbating effect of sepsis on lung pathology. Colistin, alone or with vasoconstrictive drugs, stimulated immune responses through increased inflammatory cell infiltration and the presence of lymphocytes, indicating potential immunomodulatory effects. Vasoconstriction did not alter the effects of colistin or sepsis but correlated with increased colistin levels in the lungs of septic animals. These observations suggest a potential interplay between vasoconstrictive drugs and colistin distribution/metabolism, leading to enhanced local concentrations of colistin in the lung microenvironment. The findings suggest the need for further investigations to optimize colistin and vasoconstrictive drug delivery in critically ill patients with lung pathologies. Understanding these complexities may guide more effective management of inflammatory responses and lung pathologies in these critical conditions.

Association of Length of Stay With the Clinical Trajectory of Hospitalized Patients With Atrial Fibrillation: Staying Less Is More? Am J Cardiol 2023; 206:254-261. [PMID: 37716224 DOI: 10.1016/j.amjcard.2023.08.066] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2023] [Accepted: 08/14/2023] [Indexed: 09/18/2023]
Abstract
Data predicting the length of stay (LOS) in patients with concurrent atrial fibrillation (AF) are scarce. This study aimed to investigate the potential predictors for prolonged LOS and its prognostic value. In this observational post hoc analysis of the MISOAC-AF (Motivational Interviewing to Support Oral AntiCoagulation adherence in patients with non-valvular Atrial Fibrillation) randomized trial logistic regression analyses were conducted to identify the parameters associated with prolonged LOS (defined as >7 days according to diagnostic accuracy analyses). Kaplan-Meier and Cox regression analyses were performed to generate survival curves and adjusted hazard ratios (aHRs) with 95% confidence intervals (CIs) for the primary end point of all-cause mortality and for the secondary end points during a median 3.7-year follow-up. Of the 1,057 patients studied, 462 (43.7%) were hospitalized for ≥7 days. Heart failure with reduced ejection fracture (aHR 1.75, 95% CI 1.17 to 2.63), permanent AF (aHR 1.72, 95% CI 1.29 to 2.31), history of coronary artery disease (aHR 2.32, 95% CI 1.59 to 3.39), and advanced or end-stage chronic kidney disease (aHR 1.54, 95% CI 1.15 to 2.06) were independently associated with prolonged hospitalization. Prolonged LOS was independently linked with increased all-cause mortality rates (aHR 1.68, 95% CI 1.25 to 2.26), cardiovascular mortality (aHR 1.92, 95% CI 1.36 to 2.72), major bleeding (aHR 3.07, 95% CI 1.07 to 8.78), and the composite outcome of cardiovascular death or rehospitalization (aHR 1.31, 95% CI 1.04 to 1.66). Each extra day of LOS was an independent predictor of all-cause mortality (aHR 1.03, 95% CI 1.02 to 1.04). Hospitalized patients with concurrent AF carry a substantial morbidity burden being prone to extended LOS. A jointed approach seems reasonable to reduce the LOS in patients with AF.

Multifocal Tuberculosis Verrucosa Cutis: Case Report and Review of the Literature. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1758. [PMID: 37893476 PMCID: PMC10608037 DOI: 10.3390/medicina59101758] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Revised: 09/21/2023] [Accepted: 09/28/2023] [Indexed: 10/29/2023]
Abstract
Cutaneous tuberculosis (TB) is still a major public health problem worldwide. Tuberculosis verrucosa cutis (TBVC) is a cutaneous form of exogenous TB caused by exogenous reinfection in previously sensitized individuals. TBVC typically presents as a unifocal condition. Multifocal cutaneous lesions without any other tubercular foci are extremely rare in exogenous TB and few cases are reported in the literature. We describe the first case of multifocal TBVC in an 81-year-old Greek man. In total, 14 cases of multifocal TBVC have been reported in the literature (8 males and 6 females), with mean age 47.64 years (SD = 20.75) and mean time to diagnosis of 9.69 years (SD = 15.31). Most cases (11/12) responded rapidly to treatment, implying the accuracy of diagnosis, while no one was reported to be immunocompromised. Finally, in 10 cases (71.4%), history of skin microtrauma was reported (related either to daily life habits or to professional praxis), confirming it as the main risk factor. The tuberculin skin test was positive in 10 cases and tissue culture for mycobacteria was negative in all cases. TBVC can present with multiple lesions, even in countries where TB prevalence is not high, especially in patients with history of skin abrasions. Prompt specialist assessment can expedite the establishment of diagnosis.

Head and neck follicular lymphoma with marginal zone differentiation and BCL2 translocation t(14;18) in both nodular and extranodular sites: a case report with mini-review. Oral Surg Oral Med Oral Pathol Oral Radiol 2023; 136:e139-e148. [PMID: 37516620 DOI: 10.1016/j.oooo.2023.05.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Revised: 04/26/2023] [Accepted: 05/10/2023] [Indexed: 07/31/2023]
Abstract
OBJECTIVE Head and neck follicular lymphoma (FL) with marginal zone (MZ) differentiation is a rare high-risk B-cell composite variant that has been reported in nodular but not extranodular sites in the parotid glands. Here we summarize the literature on FL with MZ differentiation in head and neck nodular sites and describe a rare case of extranodular FL with MZ differentiation in the parotid gland. STUDY DESIGN We examined both the germinal center and MZ components of the parotid and bone-marrow biopsies of a 65-year-old female histologically, immunohistochemically, and molecularly to identify B-cell, germinal center, and follicular dendritic cell markers. RESULTS The immunohistochemical and molecular analysis provided evidence that the FL and the MZ components derived from the same B-cell clone with a similar BCL2/IGH t(14;18) translocation site. The differentiated cells in the MZ did not express germinal center markers BCL6 and CD10. Both the parotid and bone-marrow proliferative B cells showed BCL6, CD2O, and CD79a positivity. CONCLUSIONS Head and neck FL with MZ differentiation can develop in both nodular and extranodular sites and is characterized by BCL2 translocation t(14;18). Although the mechanism of MZ differentiation is unclear, the characterization of this rare histopathologic phenomenon might be clinically important.

Abstract
Alzheimer's disease (AD) is an irreversible neurodegenerative disorder characterized by amyloid plaques, neurofibrillary tangles, and cerebral amyloid angiopathy (CAA). CAA is a condition manifesting as amyloid deposits in the cerebral vasculature, eventually leading to microhemorrhage. Here, we have treated the CRND8 mouse model with the C5a agonist (EP67) in order to observe the effects on cerebral amyloidosis, CAA, and hyperphosphorylated tau. EP67 attaches to the C5a receptor on phagocytes and stimulates the engulfment and digestion of fibrillar and prefibrillar amyloid while exhibiting minimal inflammation. Older CRND8 mice and their respective controls were treated with EP67 for a prolonged period of time. Following treatment, the CRND8 mice displayed improved spatial memory, while both amyloid deposition and tau hyperphosphorylation were found to be diminished.

Shadow estimation of gate-set properties from random sequences. Nat Commun 2023; 14:5039.

Abstract
With quantum computing devices increasing in scale and complexity, there is a growing need for tools that obtain precise diagnostic information about quantum operations. However, current quantum devices are only capable of short unstructured gate sequences followed by native measurements. We accept this limitation and turn it into a new paradigm for characterizing quantum gate-sets. A single experiment-random sequence estimation-solves a wealth of estimation problems, with all complexity moved to classical post-processing. We derive robust channel variants of shadow estimation with close-to-optimal performance guarantees and use these as a primitive for partial, compressive and full process tomography as well as the learning of Pauli noise. We discuss applications to the quantum gate engineering cycle, and propose novel methods for the optimization of quantum gates and diagnosing cross-talk.

Abstract
BACKGROUND Gastrointestinal stromal tumors (GISTs) are considered the most common mesenchymal tumors of the gastrointestinal tract. Microvessel density (MVD) constitutes a direct method of vascularity quantification and has been associated with survival rates in multiple malignancies.
AIM To appraise the effect of MVD on the survival of patients with GIST.
METHODS This study adhered to Systematic reviews and Meta-Analyses guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. Electronic scholar databases and grey literature repositories were systematically screened. The Fixed Effects or Random Effects models were used according to the Cochran Q test.
RESULTS In total, 6 eligible studies were identified. The pooled hazard ratio (HR) for disease free survival (DFS) was 8.52 (95%CI: 1.69-42.84, P = 0.009). The odds ratios of disease-free survival between high and low MVD groups at 12 and 60 mo did not reach statistical significance. Significant superiority of the low MVD group in terms of DFS was documented at 36 and 120 mo (OR: 8.46, P < 0.0001 and OR: 22.71, P = 0.0003, respectively) as well as at metastases rate (OR: 0.11, P = 0.0003).
CONCLUSION MVD significantly correlates with the HR of DFS and overall survival rates at 36 and 120 mo. Further prospective studies of higher methodological quality are required.

One T Gate Makes Distribution Learning Hard. PHYSICAL REVIEW LETTERS 2023; 130:240602.

Abstract
The task of learning a probability distribution from samples is ubiquitous across the natural sciences. The output distributions of local quantum circuits are of central importance in both quantum advantage proposals and a variety of quantum machine learning algorithms. In this work, we extensively characterize the learnability of output distributions of local quantum circuits. Firstly, we contrast learnability with simulatability by showing that Clifford circuit output distributions are efficiently learnable, while the injection of a single T gate renders the density modeling task hard for any depth d=n^{Ω(1)}. We further show that the task of generative modeling universal quantum circuits at any depth d=n^{Ω(1)} is hard for any learning algorithm, classical or quantum, and that for statistical query algorithms, even depth d=ω[log(n)] Clifford circuits are hard to learn. Our results show that one cannot use the output distributions of local quantum circuits to provide a separation between the power of quantum and classical generative modeling algorithms, and therefore provide evidence against quantum advantages for practically relevant probabilistic modeling tasks.

Critical-Illness: Combined Effects of Colistin and Vasoactive Drugs: A Pilot Study. Antibiotics (Basel) 2023; 12:1057.

Abstract
Colistin is often used as a last resort for treating multidrug-resistant infections, particularly in critically ill patients in intensive care units. Nonetheless, its side effects, including myopathy, require careful monitoring. Vasoconstrictive drugs are also used in intensive care to increase blood pressure and improve blood flow to vital organs, which can be compromised in critically ill patients. The exact mechanism of colistin-induced muscle toxicity is of significant interest due to its potential intensive-care clinical implications. Colistin alone or in combination with vasoconstrictive agents was administrated in non-septic and LPS-induced septic animals for 10 days. Histopathological evaluation of the gastrocnemius muscle and dot-blot protein tissue analysis were performed. Increased intramuscular area, de-organization of the muscle fibers and signs of myopathy were observed in colistin-treated animals. This effect was ameliorated in the presence of vasoconstrictive drugs. Administration of colistin to septic animals resulted in a decrease of AMPK and cyclin-D1 levels, while it had no effect on caspase 3 levels. Vasoconstrictive drugs' administration reversed the effects of colistin on AMPK and cyclin D1 levels. Colistin's effects on muscle depend on septic state and vasoconstriction presence, highlighting the need to consider these factors when administering it in critically ill patients.

Abstract
Dysphagia is a common clinical symptom in older people that can be attributed to a wide range of diseases, extending from neoplasm to gastroesophageal reflux diseases such as stroke or achalasia. We are presenting a case of a 78-year-old male with a history of heart failure with preserved ejection fraction and progressive dysphagia, due to a rare case, namely, dysphagia megalatriensis. Even though left ventricular ejection fraction was preserved, the patient improved, when we provided him with optimal medical heart failure with reduced ejection fraction treatment. In our case report, we intend to highlight the benefits of optimized medical therapy in a patient with heart failure with preserved ejection fraction, due to mitral valve regurgitation leading to a hugely dilated left atrium.

Abstract
CASE We describe the case of a 53-year-old male patient with a history of acute carpal tunnel syndrome (CTS) provoked by a radio-opaque mass on the palmar side of the wrist. Although the mass disappeared in new radiographs 6 weeks later without any intervention apart from the carpal tunnel release, excisional biopsy was conducted on the residue, revealing tumoral calcinosis. CONCLUSION Both acute CTS and spontaneous resolution are clinical manifestations of this rare condition on suspicion of which biopsy can be avoided by following a "wait and see" strategy.

Abstract
Pigmented villonodular synovitis (PVNS) is a proliferative, recurrent and locally invasive disease of the synovium. The symptoms of the disorder are not typical and thus it is very often misdiagnosed. Most of the times, magnetic resonance imaging presents the nodular model of development and sets the basis for the diagnosis. The final diagnosis will be set by the pathological evaluation of the lesion's biopsy. PVNS may be localized (nodule with a clear boundary with/without presence of single pedicle) or diffuse (extensive involvement of the adjacent nerves and vessels). Depending on the extension of the PVNS, a different management approach is performed, lesion excision vs. resection, followed by radiotherapy respectively. We report a case of diffuse PVNS in the knee joint, treated with surgical excision and adjuvant radiotherapy as well as follow-up imaging after a time period of 3 years.

Abstract
Abstract
Background
Over the past two years, Coronavirus Disease (COVID-19) and associated complications, including hypercoagulopathy, is a routine in our hospitals. We already know, that hospitalized critical ill patients with COVID-19 pneumonia, have an increased risk for Pulmonary Embolism (PE). However, only limited data refer to the potential risk in post-COVID-19 patients, and fewer, in patients who had mild disease. We define as mild COVID -19, cases that either didn't need hospitalization or they were hospitalized without respiratory complications. The incidence of PE in post-COVID-19 patients who had only mild symptoms remains unknown.
Material and methods
We are presenting a case series of five patients with mild COVID-19 infection, from our hospital, who presented with PE during the post COVID-19 infectious period. All of the patients presented mild symptoms during the infectious period. One among them needed a short duration of hospitalization for the COVID-19 infection and another one needed hospitalization due to an established stroke.
Results and conclusions
Our cases advocate that even mild COVID-19 could be considered a potential risk factor for PE, after the infectious period. According to our case series, the mean susceptible period in which post-COVID-19 patients may present PE is 21,6 days. However, the time frame in which these patients are more vulnerable to developing PE is not yet known. Nevertheless, the fact that PE occurs even in past mild disease, reinforces the idea that COVID-19 is an independent and cumulative risk factor predisposing to PE.

Abstract
The Criminal Narrative Experience (CNE) is a framework developed within Invest-igative Psychology, which combines the emotions and narrative roles experienced by the offender during the commission of their offense, to understand their personal experience of crime . Previous research proposes four distinct themes within CNE; The Elated Hero, The Calm Professional, The Distressed Revenger, and The Depressed Victim , however little attention has yet been paid to the potential differences in themes across various offense types. The current study explored the CNE model within a sample of sexual offenders. Results found evidence of two CNE themes; The Intrepid Professional-Adventurer and The Dejected Revenger-Victim, this has implications stretching further than theorical, and are particularly poignant for therapists and treatment managers, who may be providing intervention to groups of sexual offenders at any one time.

Microvessel density in differentiated thyroid carcinoma: A systematic review and meta-analysis. World J Methodol 2022; 12:448-458. [PMID: 36186751 PMCID: PMC9516550 DOI: 10.5662/wjm.v12.i5.448] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Revised: 12/30/2021] [Accepted: 07/18/2022] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Microvessel density (MVD) has been proposed as a direct quantification method of tumor neovascularization. However, the current literature regarding the role of MVD in differentiated thyroid carcinoma (DTC) remains inconclusive.
AIM To appraise the effect of tumoral MVD on the survival of patients with DTC.
METHODS This meta-analysis was based on the PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. The electronic databases Medline, Web of Science, and Scopus were systematically screened. A fixed-effects or random-effects model was used, according to the Cochran Q test. The data were then extracted and assessed on the basis of the Reference Citation Analysis (https://www.referencecitationanalysis.com/).
RESULTS A total of nine studies were included in the present study. Superiority of low MVD tumors in terms of 10-year disease free survival (OR: 0.21, 95%CI: 0.08–0.53) was recorded. Lowly vascularized thyroid cancers had a lower recurrence rate (OR: 13.66, 95%CI: 3.03–61.48). Moreover, relapsing tumors [weighed mean difference (WMD): 11.92, 95%CI: 6.32–17.52] or malignancies with regional lymph node involvement (WMD: 8.53, 95%CI: 0.04–17.02) presented with higher tumoral MVD values.
CONCLUSION MVD significantly correlates with the survival outcomes of thyroid cancer patients. However, considering several study limitations, further prospective studies of higher methodological and quality level are required.

Abstract
Correctly diagnosing a rare childhood cancer such as sarcoma can be critical to assigning the correct treatment regimen. With a finite number of pathologists worldwide specializing in pediatric/young adult sarcoma histopathology, access to expert differential diagnosis early in case assessment is limited for many global regions. The lack of highly-trained sarcoma pathologists is especially pronounced in low to middle-income countries, where pathology expertise may be limited despite a similar rate of sarcoma incidence. To address this issue in part, we developed a deep learning convolutional neural network (CNN)-based differential diagnosis system to act as a pre-pathologist screening tool that quantifies diagnosis likelihood amongst trained soft-tissue sarcoma subtypes based on whole histopathology tissue slides. The CNN model is trained on a cohort of 424 centrally-reviewed histopathology tissue slides of alveolar rhabdomyosarcoma, embryonal rhabdomyosarcoma and clear-cell sarcoma tumors, all initially diagnosed at the originating institution and subsequently validated by central review. This CNN model was able to accurately classify the withheld testing cohort with resulting receiver operating characteristic (ROC) area under curve (AUC) values above 0.889 for all tested sarcoma subtypes. We subsequently used the CNN model to classify an externally-sourced cohort of human alveolar and embryonal rhabdomyosarcoma samples and a cohort of 318 histopathology tissue sections from genetically engineered mouse models of rhabdomyosarcoma. Finally, we investigated the overall robustness of the trained CNN model with respect to histopathological variations such as anaplasia, and classification outcomes on histopathology slides from untrained disease models. Overall positive results from our validation studies coupled with the limited worldwide availability of sarcoma pathology expertise suggests the potential of machine learning to assist local pathologists in quickly narrowing the differential diagnosis of sarcoma subtype in children, adolescents, and young adults.

Abstract
Alzheimer’s disease (AD) is a progressive neurodegenerative disease of the brain causing either familial or sporadic dementia. We have previously administered the modified C5a receptor agonist (EP67) for a short period to a transgenic mouse model of AD (5XFAD) and have observed not only reduction in β-amyloid deposition and gliosis but also improvement in cognitive impairment. Inquiring, however, on the effects of EP67 in an already heavily burdened animal, thus representing a more realistic scenario, we treated 6-month-old 5XFAD mice for a period of 14 weeks. We recorded a significant decrease in both fibrillar and pre-fibrillar β-amyloid as well as remarkable amelioration of cognitive impairment. Following proteomic analysis and pathway association, we postulate that these events are triggered through the upregulation of β-adrenergic and GABAergic signaling. In summary, our results reveal how inflammatory responses can be employed in inducing tangible phenotype improvements even in advanced stages of AD.

Abstract
BACKGROUND We investigated the effect of crocin treatment on atherosclerosis and serum lipids in apolipoprotein E knockout (ApoE-/-) mice, focusing on the expression of endothelial nitric oxide synthase (eNOS) and hypoxia-induced factor-1 alpha (HIF-1α). METHODS Sixty-two animals were divided into two groups and randomly allocated to crocin (100 mg/kg/day) in drinking water or no crocin. All mice were maintained on standard chow diet containing 5% fat. Crocin was initiated at the 16th week of age and continued for 16 additional weeks. At 32 weeks of age, after blood sampling for plasma lipid determination and euthanasia, proximal aorta was removed and 3 μm sections were used to measure the atherosclerotic area and determine the expression of eNOS and HIF-1α by immunohistochemistry. RESULTS Each group consisted of 31 animals (17 males and 14 females in each group). Crocin significantly reduced the atherosclerotic area (mm2 ± SEM) in treated mice compared to controls, both in males (0.0798 ± 0.017 vs. 0.1918 ± 0.028, P < 0.002, respectively) and females (0.0986 ± 0.023 vs. 0.1765 ± 0.025, P < 0.03, respectively). eNOS expression was significantly increased in crocin-treated mice compared to controls, both in males (2.77 ± 0.24 vs. 1.50 ± 0.34, P=0.004, respectively) and females (3.41 ± 0.37 vs. 1.16 ± 0.44, P=0.003, respectively). HIF-1α expression was significantly decreased in crocin-treated mice compared to controls, both in males (21.25 ± 2.14 vs. 156.5 ± 6.67, P < 0.001, respectively) and females (35.3 ± 7.20 vs. 113.3 ± 9.0, P < 0.01, respectively). No difference was noticed in total, low- and high-density lipoprotein cholesterol between treated and control mice. CONCLUSION Crocin reduces atherosclerosis possibly by modulation of eNOS and HIF-1α expression in ApoE-/- mice without affecting plasma cholesterol.

Abstract
Enterobacteriaceae are a family of bacteria, including many familiar pathogens that cause signs of diarrhoea in humans and animals, such as Escherichia coli, Salmonella, Shigella, and Klebsiella. Enterobacteriaceae, the first Gram-negative bacteria, are bacilli (rod-shaped) facultative anaerobes. They ferment sugars to produce lactic acid and other end products. They are usually about 1-5 μm in length. Most are motile because of many flagella; however, a few genera are non-motile. They do not form spores. Most Enterobacteriaceae members have fimbriae necessary for the adhesion of the bacterial cells to their hosts. They are economically significant and thus a considerable concern because they cause the deaths of millions of people each year, resulting in a significant situation to curb their infection. Due to the emergence of drug-resistant bacteria, there is an urgency to search for replacement therapies against bacteria in the Enterobacteriaceae family. To find a solution to this traumatic problem, studies have been launched in the areas of bacteriophages and their therapeutic application as a significant replacement for antibiotics. Bacteriophage therapy utilizes a different mechanism in destroying bacteria; hence, it is a better alternative to antibiotics. This review sheds light on Enterobacteriaceae and bacteriophage therapy, as well as the history of bacteriophage therapy, its mode of lysing bacteria and formulations of phages.

Abstract
BACKGROUND AND AIMS Little is known about the impact of DNA methylation modifications on autoimmune hepatitis (AIH) pathogenesis and therapeutic response. We investigated the potential alterations of DNA methylation in AIH peripheral lymphocytes at diagnosis and remission. METHODS Ten AIH patients at diagnosis (time-point 1; AIH-tp1), 8/10 following biochemical response (time-point 2; AIH-tp2), 9 primary biliary cholangitis (PBC) and 10 healthy controls (HC) were investigated. Peripheral CD19(+) and CD4(+) cells were isolated. Global DNA methylation (5m C)/hydroxymethylation (5hm C) was studied by ELISAs. mRNA of DNA methylation (DNMT1/3A/3B) and their counteracting hydroxymethylation enzymes (TET1/2/3) was determined by quantitative RT-PCR. Epigenome wide association study (EWAS) was performed in CD4(+) cells (Illumina HumanMethylation 850 K array) in AIH and HC. Total 5m C/5hm C was also assessed by immunohistochemistry (IHC) on paraffin-embedded liver sections. RESULTS Reduced TET1 and increased DNMT3A mRNA levels characterized CD19(+) and CD4(+)-lymphocytes from AIH-tp1 compared to HC and PBC, respectively, without affecting global DNA 5m C/5hm C. In AIH-tp1, CD4(+) DNMT3A expression was negatively correlated with serum IgG (P = .03). In remission, DNMT3A decreased in both CD19(+) and CD4(+) cells compared to AIH-tp1 (P = .02, P = .03 respectively). EWAS in CD4(+) cells from AIH patients confirmed important modifications in genes implicated in immune responses (HLA-DP, TNF, lnRNAs and CD86). IHC showed increased 5hm C staining of periportal infiltrating lymphocytes in AIH-tp1 compared to HC and PBC. CONCLUSION Altered TET1 and DNMT3A expressions, characterize peripheral lymphocytes in AIH. DNMT3A was associated with disease activity and decreased following remission. Gene DNA methylation modifications affect immunological pathways that may play an important role in AIH pathogenesis.

Abstract
BACKGROUND/AIM Pancreatic cancer (PC) is one of the leading causes of cancer-related death. The purpose of the present study was to establish a patient-derived orthotopic xenograft model (PDOX) for pancreatic ductal adenocarcinoma (PDAC), thus providing a tumor microenvironment resembling that of the human pancreas to identify novel potential biomarkers and treatment regimens. MATERIALS AND METHODS PDAC tissue samples were received from 35 patients, following informed consent, and three mouse strains were implemented. RESULTS Successful PDOX engraftment was performed in nonobese diabetic/severe combined immunodeficient (NOD/SCID) and NOD/SCID gamma (NSG) mice. Nonetheless, we found a higher rate of successful engraftment and tumor growth in NSG compared to NOD/SCID mice, possibly owning to the different level of immunosuppression and more specifically of the natural killer cells presence. CONCLUSION Our suggested PDOX model represents a preclinical cancer research model with a high affinity for the patient's tumor microenvironment, thus enabling the acceleration of PDAC research.

Abstract
Prostate cancer is one of the most commonly diagnosed malignancies in men. Most of these tumors are adenocarcinomas. Plasmacytoid is a rare variant of adenocarcinoma described by previous studies in the genitourinary system and is characterized by the plasmacytoid appearance of tumor cells with abundant cytoplasm and abnormally placed hyperchromatic nuclei. However, to the best of our knowledge, plasmacytoid adenocarcinoma has rarely been described in the prostate. This report describes a new case of plasmacytoid adenocarcinoma of the prostate diagnosed by biopsy and summarizes the known literature on plasmacytoid features in the genitourinary system. A 62-year-old male patient presented to the hospital with urinary retention, hematuria, weakness and weight loss. The digital rectal examination revealed an irregular enlargement. Laboratory findings showed elevated levels of prostate specific antigen (PSA; 43.6 ng/ml). Transrectal ultrasound showed invasion of the right seminal vesicle. Prostate tumor core biopsies were collected and sent for diagnosis. Histological examination revealed a high-grade prostatic adenocarcinoma Gleason score of 5+5 (total score 10). The tumor cells had a plasmacytoid appearance with abundant cytoplasm and abnormally placed hyperchromatic nuclei. The immunohistochemical phenotype was characterized by abundant positivity for cytokeratin (CK)AE1/AE3 and PSA. By contrast, tumor cells were negative for p63, CK 34BE12 and GATA binding protein 3 (urothelial markers), synaptophysin (neuroendocrine marker). Tumor cells were also negative for E-cadherin, which is particularly indicative of CDH1 alterations. To the best of our knowledge, this is the first description of a plasmacytoid adenocarcinoma of the prostate diagnosed by biopsy, showing an irregular immunophenotype that may indicate somatic CDH1 alterations. The presentation of a novel rare variant of prostatic carcinoma that differs from other neoplasms of the genitourinary system may contribute to an improved understanding of this uncommonly found histological pattern that may also be mandatory due to the clinical and prognostic implications of this diagnosis.

Abstract
Although COVID-19 was primarily considered a respiratory illness, rapidly accumulating data suggest that COVID-19 is associated with a high incidence of venous thromboembolic complications. The primary objective of this review article was to reveal whether we need to increase awareness of pulmonary embolism in the period following the COVID-19 infection given that the epidemiologic facts are still poor. A literature search and a critical review of the collected studies were conducted. An electronic search of PubMed, Science Direct Scopus, Google Scholar, and Excerpta Medica Database (EMBASE) from June 2020 until June 2022. The long-term health consequences of COVID-19 remain largely unclear. This review highlights the importance of awareness of the potentially increased incidence of venous thromboembolism in post-COVID-19 patients, even those with mild or asymptomatic disease. Further research is required to establish appropriate clinical management guidelines for the prevention of thromboembolic complications in the post-COVID-19 period.

Abstract
OBJECTIVES Metabolic syndrome (MetS) is highly prevalent among patients with bipolar disorder (BD). The aims of this cross-sectional study were to determine the prevalence of MetS in Dutch BD subjects and compare it with a control group, to examine the association of demographic and clinical characteristics with MetS in BD, and to determine the extent to which metabolic dysregulation is treated in those patients. METHODS 493 Dutch adult patients (≥ 18 years) with BD receiving psychotropic drugs and 493 matched control subjects were compared using data from the biobank Lifelines. We determined MetS according to the National Cholesterol Education Program Adult Treatment Panel III-Adapted (NCEP ATP III-A) criteria. The difference in the prevalence of MetS and the associations with characteristics were analyzed with logistic regression. RESULTS BD subjects (30.6%) showed a significantly higher prevalence of MetS compared to the control group (14.2%) (p < .001, OR:2.67, 95% CI:1.94-3.66). Univariate analysis showed that smoking, body mass index (BMI) and antidepressant drug use were associated with MetS. Multivariate analysis showed that smoking (OR:2.01) was independently associated with MetS in BD. For hypertension, hyperglycemia and lipid disorder pharmacological treatment was provided to respectively 69.5%, 24% and 18.4% of the BD subjects in our sample. LIMITATIONS Duration of illness of BD subjects was unknown. CONCLUSIONS This study demonstrated a higher prevalence of MetS in Dutch BD subjects compared to persons without BD. In addition, a remarkable undertreatment of some of the components of MetS was found.

Abstract
The renin-angiotensin system (RAS), besides being a major regulator of blood pressure, is also involved in tumor angiogenesis. Emerging evidence suggests a correlation between the use of pharmacologic RAS inhibitors and a delay in urothelial bladder cancer (BC) progression. However, it is unknown whether RAS gene variants may predispose to the development of BC. This study examined the association of RAS single nucleotide polymorphisms (SNPs) including AT1R rs5186, AT2R rs11091046, REN rs12750834, ANG rs4762, and ANG rs699 with the risk of developing non-invasive BC. Peripheral blood samples from 73 patients with T1 urothelial BC (66 men, seven women) and an equal number of healthy subjects (control group) were collected. The TT genotype of the REN rs12750834 SNP (OR: 2.8 [1.3–6.05], p = 0.008) and to a lesser extent the presence of the T allele (OR: 2.3 [1.2–4.48], p = 0.01) conferred a higher risk of BC. The highest risk for BC within SNP carriers of the RAS system was associated with the presence of the CC genotype (OR: 17.6 [7.5–41.35], p < 0.001) and C allele (OR: 17.7 [8.8–35.9], p < 0.001) of the ANG rs699 SNP. The presence of the AT2R rs11091046 SNP, particularly the AA genotype, was associated with a protective effect against developing BC (OR: 0.268 [0.126–057], p < 0.001). In conclusion, these results support the clinical utility of RAS gene SNPs AT2R rs11091046, REN rs12750834, and ANG rs699 in the genetic cancer risk assessment of patients and families with BC.

Abstract
AbstractWhen a child goes missing it is common practice to release an appeal of the child in the hope that a member of the public could help to identify and locate them. Despite being an everyday occurrence, there remains a significant gap in our understanding of how effective these appeals are. The present study sought to explore the effectiveness of missing children appeals through the recall accuracy of the general public immediately after observing the appeals and again after a three-day delay. One hundred and eighty-two participants observed either a mock Child Rescue Alert or a mock Twitter appeal. The results found no significant difference in recall accuracy between the design of the appeals although there was a significant difference in recall error. Confidence in own recall accuracy and the length of time spent observing the appeals were also found to be significantly associated with recall accuracy. Initial recall accuracy scores were significantly higher than recall accuracy scores following a three-day break. This exploratory study demonstrates the requirement to improve missing children appeals and lays the foundation for future studies to build on these findings further.

Abstract
Diverse lines of research testify a link, presumably causal, between immune dysregulation and the development, course and clinical outcome of psychiatric disorders. However, there is a large heterogeneity among the patients' individual immune profile and this heterogeneity prevents the development of precise diagnostic tools and the identification of therapeutic targets. The aim of this review was to delineate possible subgroups of patients on the basis of clinical dimensions, investigating whether they could lead to particular immune signatures and tailored treatments. We discuss six clinical entry points; genetic liability to immune dysregulation, childhood maltreatment, metabolic syndrome, cognitive dysfunction, negative symptoms and treatment resistance. We describe the associated immune signature and outline the effects of anti-inflammatory drugs so far. Finally, we discuss advantages of this approach, challenges and future research directions.

The Relationship between Dark Triad Personality Traits and Sexting Behaviors among Adolescents and Young Adults across 11 Countries. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18052526. [PMID: 33806314 PMCID: PMC7967332 DOI: 10.3390/ijerph18052526] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/31/2021] [Revised: 02/21/2021] [Accepted: 02/25/2021] [Indexed: 02/07/2023]
Abstract
Background: Sexting is an increasingly common phenomenon among adolescents and young adults. Some studies have investigated the role of personality traits in different sexting behaviors within mainstream personality taxonomies like Big Five and HEXACO. However, very few studies have investigated the role of maladaptive personality factors in sexting. Therefore, the present study investigated the relationship between Dark Triad Personality Traits and experimental (i.e., sharing own sexts), risky (i.e., sexting under substance use and with strangers), and aggravated sexting (i.e., non-consensual sexting and sexting under pressure) across 11 countries. Methods: An online survey was completed by 6093 participants (Mage = 20.35; SDage = 3.63) from 11 different countries which covered four continents (Europe, Asia, Africa, and America). Participants completed the Sexting Behaviors Questionnaire and the 12-item Dark Triad Dirty Dozen scale. Results: Hierarchical regression analyses showed that sharing own sexts was positively predicted by Machiavellianism and Narcissism. Both risky and aggravated sexting were positively predicted by Machiavellianism and Psychopathy. Conclusions: The present study provided empirical evidence that different sexting behaviors were predicted by Dark Triad Personality Traits, showing a relevant role of Machiavellianism in all kinds of investigated sexting behaviors. Research, clinical, and education implications for prevention programs are discussed.

Abstract
Hemophagocytic lymphohistiocytosis (HLH), or hemophagocytic syndrome (HS) is a severe syndrome involving an extreme participation of the immune system, resulting in a cascade of cytokines, hyperinflammation and extensive hemophagocytosis in the bone marrow (BM) and affecting the peripheral blood (PB) lineages. Fever, splenomegaly, hypertriglyceridemia, hypofibrinogenemia, and hyperferritinemia are often encountered in this disease. The syndrome can be seen in all ages and it is either primary due to genetic defects or secondary because of malignancies, immune deficiencies, rheumatic diseases, and infections. Bacteria, viruses, protozoa, and fungi are often implicated. Visceral leishmaniasis (VL) is among the infectious causes of HLH. We describe a patient with a successful treatment of HLH after the initiation of liposomal amphotericin B, due to VL, even though there was a delay in diagnosing the leishmaniasis. The exact precipitating pathophysiological events triggering HLH remain unknown and provide their clear impact for future research. An instructive, critical review of the literature related to the presented case is provided. Distinguishing secondary HS from primary HS is essential for the application of suitable treatment. Improper use of corticosteroids could cover up an underlying possible malignancy or infection and delay the initiation of the etiologic therapeutic strategy.

Abstract
CASE PRESENTATION A 71-year-old ex-bus driver (ex-smoker, 20 pack-years) was admitted for the first time to the respiratory department because of chronic dry cough and progressive exertional dyspnea with insidious onset 8 years ago. The patient also reported weight loss of about 20 kg in 3 years and proximal muscle weakness. A decade ago, he was diagnosed with gastric adenocarcinoma and subjected to partial gastrectomy and splenectomy, followed by an unspecified chemotherapy regimen. Additionally, the patient has coronary disease and underwent coronary bypass graft surgery 7 years ago. In the course of his disease, many diagnostic procedures have been performed including Mantoux tests, five CT scans, a CT-guided biopsy, two bronchoscopies, and an 18F-fluorodeoxyglucose PET scan with inconclusive results. The patient was referred to the hospital to have his long-lasting condition diagnosed and treated.

Abstract
Alveolar rhabdomyosarcoma (ARMS), a histological subtype of rhabdomyosarcoma (RMS), is characterized by an unfavorable clinical outcome. In most ARMS cases, an indicative chromosomal alteration is identified. The recurrent translocation of FKHR with either PAX3 or PAX7 genes results in the encoding of chimeric transcription factors that boost tumorigenesis. Besides structural mutations, the copy number of these genes also contributes to the oncogenic activity. In our case, a 12-year-old female patient was diagnosed with a 4 cm pelvic mass. Histopathological examination indicated an alveolar type of RMS. Subsequent FISH analysis with a dual color break-apart probe identified positive signals of FKHR3 gene break, as well as the rare event of a synchronous aneuploidy and gene deletion of FKHR. Our findings lead to the conclusion that a systematic break-apart probe FKHR FISH analysis in ARMS, confirms the diagnosis and elucidates the full spectrum of genomic alterations of this malignancy.

Abstract
Given the challenges associated with psychopathic and personality disordered offenders, further insight is needed. One way of doing this is by looking at offending from the first-person perspective. The study investigated the criminal narrative experience (CNE) of this population during the commissioning of crimes. Twenty-two high-risk male offenders were recruited and a questionnaire design was used. The data were analysed using Smallest Space Analysis which revealed four themes consistent with Ioannou, Canter, and Youngs's CNE framework: depressed victim, distressed revenger, calm professional, and elated hero. Independent samples t tests explored whether personality disorders related to CNE themes, and Pearson's product-moment correlation was used to explore the relationship between psychopathy and the CNE themes. Borderline personality disorder identified with the depressed victim. Paranoid and schizoid personality disorders did not identify with the calm professional. There was no significant relationship between psychopathy and the CNE themes. The theoretical and practical implications are discussed.

Abstract
OBJECTIVES Angiogenesis plays a major role in tumor progression and metastasis; however, its role in pancreatic cancer (PC) remains unclear. The aim of the study was to explore the cumulative evidence concerning the impact of microvessel density (MVD), an estimator of angiogenesis, on resected PC patients. METHODS A systematic review of literature and a meta-analysis of relevant reports were performed. Overall survival and disease-free survival were scrutinized. RESULTS One thousand five hundred patients were analyzed. Overall survival (hazard ratio, 2.0; 95% confidence interval, 1.57-2.54; P < 0.001) and disease-free survival (hazard ratio, 1.99; 95% confidence interval, 1.24-3.2; P = 0.004) were in favor of the low-MVD group. Use of CD105 antibody and of a computerized image analysis system was found to significantly reduce the heterogeneity. Disease staging, tumor location, and grading showed significant effect on survival. CONCLUSIONS High-MVD expression was strongly associated with poorer survival and recurrence among resected PC patients, demonstrating a negative prognostic value. Use of CD105 antibody and of a computerized image analysis system is recommended in future studies because they reduce heterogeneity of results. The potential role of MVD as a marker to select PC patients who would benefit from antiangiogenetic treatment should be further explored in clinical trials.

Abstract
Neoangiogenesis has been demonstrated in chondrosarcoma. Anti-angiogenic therapies are being tested in clinical trials for chondrosarcomas. Studies of the underlying mechanisms have been performed almost exclusively in cell lines. We immunostained 20 samples of chondrosarcoma and 20 samples of enchondromas with antibodies against hypoxia-inducible factor 1-alpha (HIF-1-alpha) and vascular endothelial growth factor (VEGF). The immunohistochemical staining of HIF-1-alpha and VEGF were highly correlated. Enchondromas were HIF-1-alpha and VEGF negative, whereas all chondrosarcoma exhibited HIF-1-alpha and VEGF immunostaining. HIF-1-alpha/VEGF double positive cases were almost exclusively chondrosarcomas with a high tumor grade. We suggest that HIF-1-alpha is a marker of malignancy in chondrosarcomas that correlates with tumor neo-angiogenesis. Our findings also suggest that a HIF-1-alpha/VEGF angiogenic pathway may exist in chondrosarcoma in vivo as in other malignant tumors. The inclusion of novel inhibitors to HIF-1-alpha and other factors may optimize anti-angiogenic interventions in chondrosarcoma.

Abstract
Aspergillosis, which is saprophytic in nature, is known to cause massive destruction of paranasal sinuses in immunocompromised hosts, but in immunocompetent individuals invasive aspergillosis is rare. Diagnosis is posed from history, physical examination including anterior and posterior rhinoscopy, endoscopy of the nose and paranasal sinuses, radiological findings (CT and/or MRI), fungus cultures and histopathological examination. Non-specific presenting symptoms provide time for infection to extent from sinuses to vital surroundings such as bony, vascular and central nervous system structures, thereby increasing morbidity and mortality. Mass lesions involving the sinuses are initially misdiagnosed as tumors, inflammatory pseudotumors or pituitary adenomas. Therefore, diagnosis should be always confirmed by histopathology. Aspergillus sinusitis is a potentially fatal complication of immunosupression or of chemotherapy-induced leucopenia. Concerning patients with hematologic malignancies, it seems that its incidence is progressively increased. A combination of early diagnosis and application of specific antifungals provides the perfect management and prognosis in the corresponding patients. In the current special review, we present new data regarding the infection in patients with hematologic malignancies.

Abstract
Fifty suicide notes of those who died by suicide and 50 suicide notes of those who survived their suicide attempt were analyzed using Smallest Space Analysis. The core of all suicide notes was discovered to be constructed with the use of four variables: saying goodbye to their audience, feelings of loneliness, method used to attempt suicide, and negative self-image. Furthermore, three different suicide note themes of those who died and three suicide note themes from those who survived were also identified. The analysis revealed that suicide note writers who died by their attempt were more likely to combine a dislike of themselves and a concern for loved ones. The implications of the work in terms of suicide prevention are discussed.
