The experiences of men who self-harm:A qualitative analysis

This thesis is comprised of four chapters, including a systematic literature review, an empirical research paper, a critical appraisal, and the ethics application section. The systematic literature review offers a meta-synthesis of the published literature exploring the experiences of men who self-harm in forensic secure hospitals and prisons. Five papers were included in the review, four were conducted in prisons and one in a forensic secure hospital. The results were synthesised using a meta-ethnographic approach. The empirical paper is a qualitative investigation that explores the experiences of young men who self-harm, attending to the relational and communicative aspects of these behaviours. This study utilised semistructured interviews to gather the perspectives of five young men who self-harm and the data was analysed using Interpretative Phenomenological Analysis. The critical appraisal offers an overview of both papers, highlighting the main findings, as well as difficulties that arose during the research process, and the key clinical and research implications of the whole thesis. Personal reflections are also offered. The last section includes the ethics application process of the empirical paper and the supporting documents utilised in the process

COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study

Background: The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms. Methods: International, prospective observational study of 60 109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms. Results: ‘Typical’ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (≤ 18 years: 69, 48, 23; 85%), older adults (≥ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P < 0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country. Interpretation: This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men

Physical Activity in Patients with Advanced Cancer: Sociodemographic, Clinical, and Psychological Correlates

As cancer progresses, patients may experience physical decline, which can impair their ability to carry out essential daily tasks. The aim of this study was to analyze the levels of physical activity in patients with advanced cancer undergoing systemic treatment and its relationship with sociodemographic, clinical, and psychological factors. A prospective, cross-sectional, multicenter study was carried out in 15 oncology departments in Spain. Patients with locally advanced, unresectable, or metastatic cancer who were candidates for systemic treatment were included. Participants completed demographic information and psychological scales. In total, 508 patients were included in the study, the majority of whom were male, over the age of 65, and diagnosed with bronchopulmonary tumors (36%) and metastatic disease. Based on their physical activity levels, participants were categorized as sedentary (20%, n = 190), engaging in light physical activity (43%, n = 412), or demonstrating moderate physical activity (37%, n = 351). Patients who were over 65 years old; had a worse baseline status (ECOG ≥ 1); lacked a partner; had a lower educational level; or were retired or unemployed were found to have lower levels of physical activity. Those with sedentary physical activity reported higher levels of psychological distress, anxiety, depression, somatization, and physical symptoms, as well as worse functional status, global health status, and well-being. Understanding the complex interplay between physical activity and sociodemographic, clinical, and psychological factors can help neuroscientists develop tailored exercise interventions that address the unique needs of advanced cancer patients

The histone demethylase PHF8 is a molecular safeguard of the IFNgamma response

A precise immune response is essential for cellular homeostasis and animal survival. The paramount importance of its control is reflected by the fact that its non-specific activation leads to inflammatory events that ultimately contribute to the appearance of many chronic diseases. However, the molecular mechanisms preventing non-specific activation and allowing a quick response upon signal activation are not yet fully understood. In this paper we uncover a new function of PHF8 blocking signal independent activation of immune gene promoters. Affinity purifications coupled with mass spectrometry analysis identified SIN3A and HDAC1 corepressors as new PHF8 interacting partners. Further molecular analysis demonstrated that prior to interferon gamma (IFNγ) stimulation, PHF8 is bound to a subset of IFNγ-responsive promoters. Through the association with HDAC1 and SIN3A, PHF8 keeps the promoters in a silent state, maintaining low levels of H4K20me1. Upon IFNγ treatment, PHF8 is phosphorylated by ERK2 and evicted from the promoters, correlating with an increase in H4K20me1 and transcriptional activation. Our data strongly indicate that in addition to its well-characterized function as a coactivator, PHF8 safeguards transcription to allow an accurate immune response

Prosthetic Valve Candida spp. Endocarditis: New Insights Into Long-term Prognosis—The ESCAPE Study

International audienceBackground: Prosthetic valve endocarditis caused by Candida spp. (PVE-C) is rare and devastating, with international guidelines based on expert recommendations supporting the combination of surgery and subsequent azole treatment.Methods: We retrospectively analyzed PVE-C cases collected in Spain and France between 2001 and 2015, with a focus on management and outcome.Results: Forty-six cases were followed up for a median of 9 months. Twenty-two patients (48%) had a history of endocarditis, 30 cases (65%) were nosocomial or healthcare related, and 9 (20%) patients were intravenous drug users. "Induction" therapy consisted mainly of liposomal amphotericin B (L-amB)-based (n = 21) or echinocandin-based therapy (n = 13). Overall, 19 patients (41%) were operated on. Patients <66 years old and without cardiac failure were more likely to undergo cardiac surgery (adjusted odds ratios [aORs], 6.80 [95% confidence interval [CI], 1.59-29.13] and 10.92 [1.15-104.06], respectively). Surgery was not associated with better survival rates at 6 months. Patients who received L-amB alone had a better 6-month survival rate than those who received an echinocandin alone (aOR, 13.52; 95% CI, 1.03-838.10). "Maintenance" fluconazole therapy, prescribed in 21 patients for a median duration of 13 months (range, 2-84 months), led to minor adverse effects.Conclusion: L-amB induction treatment improves survival in patients with PVE-C. Medical treatment followed by long-term maintenance fluconazole may be the best treatment option for frail patients
