Entre le spirituel et la plasticité de la matière. Lier l’inalliable à travers la suspension

Ma recherche-création vise à exprimer le sens du phénomène spiritualité, de le proposer et de l’amener à travers la matière. Entre la sculpture et l’installation j’aborde les notions d’équilibre, de suspension et de fragilité qui unissent les deux concepts antagonistes de spiritualité et de matérialité. D’où mes interrogations sur la possibilité de dévoiler l’invisible à travers le visible et de suspendre la matière pour accéder au spirituel. Je voudrais comprendre comment la suspension de matériaux peut produire l’évocation de la spiritualité. Mon intention de recherche est donc de réaliser des oeuvres qui lient l’inalliable, le spirituel et la matière à travers la suspension. Mon but est la découverte d’un nouveau mode d’expression qui me permette d’exprimer cette spiritualité qui est en moi

0528: The role of brain natriuretic peptide and cystatin C in the evaluation of left ventricular diastolic dysfunction: correlation with echocardio-graphic indexes after myocardial infarction

BackgroundThe utility of Brain Natriuretic Peptide (BNP) and cystatin C for detecting left ventricular (LV) diastolic dysfunction after myocardial infarction (MI) in patients without heart failure symptoms still unclear. In this study, we investigated the relation between BNP, serum cystatin C levels and LV diastolic dysfunction after MI in patients without systolic dysfunction.MethodsWe studied 127 patients without renal dysfunction after first acute coronary syndrome (ACS). LV diastolic function was assessed with conventional Doppler, by means of mitral inflow and with tissue Doppler echo-cardiography by means of mitral annulus. The ratio of early diastolic transmitral E wave velocities to tissue Doppler mitral annulus early diastolic E’ wave velocities (E/E’), was used to detect LV filling pressures. Patients were divided in three groups according to E/E’ ratios<10 (group I), E/E’ ratios “between” 10 and 15 (group II) and E/E’ ratios>15 (group III). Plasma concentrations of BNP and serum cystatin C were measured at admission.ResultsThe BNP and serum cystatin C levels were positively correlated significantly with E/E’ ratio (r=0.786, P<0.001 and r=0.458, p=0.02). Patients with elevated LV end diastolic pressure (LVEDP), defined as E/E’>15 had highest BNP (321±75pg/mL) and cystatin C (1.1±0.2mg/L) levels. E/E’ 10 to 15 group had a mean BNP level of 151±28pg/mL and a mean cystatin C value of 0.78±0.1mg/L, and those with E/E’<10 had a mean BNP value of 69±20pg/ mL. A BNP value of 89pg/mL had a sensitivity of 84% and a specificity of 69% for predicting E/E’>15.ConclusionThe assessment of the blood concentration of BNP and cystatin C is of potential value for identification of those patients after myocardial infarction to detect early cardiovascular changes, especially LV diastolic dys-function

A continuous murmur following a nonpenetrating chest trauma

AbstractWe reported a rare case of non-penetrating chest trauma-induced fistula from the right sinus of Valsalva to the right heart chambers. The ruptured sinus of Valsalva aneurysm was diagnosed preoperatively and operated on successfully. The rarity of this case highlights the need for a precise preoperative diagnosis, the role of transthoracic echocardiography, and the importance of a prompt surgical management

158 Prothetic abcess complicating Infective endocarditis

The cardiac abscess formation is appraised to 20–30% during the infectious endocarditis (IE). It is more frequent during prosthesis endocarditis and it can reach 60%. The prognosis is generally reserved. Objective To determine echocardiographic, bacteriological and evolutive features of prothetic IE complicated of abscess.Retrospective study including 51 patients having certain or probable IE according to Duke criterias between 2002 and 2005. At 9 patients (17,64%) the endocarditis was complicated of prothetic abscess. It was about 6 men and 3 women with a middle age of 39 ± years. IE was la ate IE in 5 cases. Clinical and biological infectious syndrome was constant. Isolated germs were staphylococcus aureus in 2 cases, GRAM négatif Bacillus in 2 cases. Culture negative endocarditis were noted in 5 cases. Brucellosis serology was positive at one patient. Prothetic abcess was diagnosed by transthoracic echocardiography (TTE) at 2 patients and by transesophagal echocardiography (TEE) at all patients.The abcess was localized on the aortic prosthesis at 5 patients, mitral prothesis at 3 patients and mitroaortic prothesis at one patient. TEE identified annular abcess at 2 patients and a myocardial abcess at 1 patient. Secondary septic localizations were noted at 6 patients: 4 cerebral abscesses, 2 splenic localization, a renal localization and an articular localization. High degree atrioventricular blocks were observed at 3 patients. The recourse to the surgery was frequent (7 patient/9 patient). It was an emergent sugery at 2 patients because of a heart failure. For the others, the indication for surgery was medical failure treatment at a mean delay of 19 days. The evolution was fatal at 5 patients. and the evolution was favorable at the others.Prothetic endocarditis complicated of abscess are serious requiring frequently a prothetic replacement, a very high risked surgery. TEE must be systematic at all patients carrier of prosthesis if they have infectious syndrome in order to carry the early diagnosis of IE and to avoid abcess formation

Bilateral atrophic squirrhus of breast in neglected breast cancer: case report

The atrophic squirrhus carcinoma is an advanced form of breast cancer, which is most often neglected by patients. These days it has become very rare. The bilaterality of this form is even more exceptional. We present a case of atrophic squirrhus breast cancer of a 58 years old woman, rural origin, which is particular for its bilaterality and rapid evolution causing the death after 22 months from the first abnormal functional sign

Effects Of Phototherapy On Serum Calcium Level In Neonates With Hyperbilirubinemia

Objective: To study the frequency of hypocalcemia in neonates receiving phototherapy with indirect hyperbilirubinemia Materials and Methods: Descriptive case series study was conducted from September 5, 2018, to March 5, 2019, in the NICU of the Paediatric Department Benazir Bhutto Hospital, Rawalpindi. Approval was sought from the hospital’s ethical committee. Neonates fulfilling inclusion criteria were enrolled in the study after obtaining informed consent from the parents. Before giving phototherapy, serum calcium levels were checked. Phototherapy was given for 48 hours. Serum calcium levels were reassessed after 48 hours of phototherapy. Data was entered on a structured proforma and statistical analysis of data was performed. Results: Out of 150 patients enrolled in the study 83(55.33%) were male and 67(44.67%) were female. The mean age of patients was 52.52 hours with minimum and maximum ages of 26 hours and 80 hours. The mean Indirect serum bilirubin level was 15.59 ± 2.36. A total of 50(33.33%) cases had hypocalcemia after 48 hours of phototherapy, all of these neonates had normal calcium levels before phototherapy. When hypocalcaemia was stratified for gestational age, birth weight and serum bilirubin levels at baseline, there was no significant difference in the frequency of hypocalcaemia concerning these effect modifiers. Conclusion: It is concluded that the frequency of hypocalcemia is higher in neonates with indirect hyperbilirubinemia after receiving phototherapy. One needs to be vigilant in dealing with neonates in this context, while serial measurements of calcium levels and monitoring for complications of hypocalcaemia should be included in every institution’s polic

Infected pancreatic necrosis: outcomes and clinical predictors of mortality. A post hoc analysis of the MANCTRA-1 international study

: The identification of high-risk patients in the early stages of infected pancreatic necrosis (IPN) is critical, because it could help the clinicians to adopt more effective management strategies. We conducted a post hoc analysis of the MANCTRA-1 international study to assess the association between clinical risk factors and mortality among adult patients with IPN. Univariable and multivariable logistic regression models were used to identify prognostic factors of mortality. We identified 247 consecutive patients with IPN hospitalised between January 2019 and December 2020. History of uncontrolled arterial hypertension (p = 0.032; 95% CI 1.135-15.882; aOR 4.245), qSOFA (p = 0.005; 95% CI 1.359-5.879; aOR 2.828), renal failure (p = 0.022; 95% CI 1.138-5.442; aOR 2.489), and haemodynamic failure (p = 0.018; 95% CI 1.184-5.978; aOR 2.661), were identified as independent predictors of mortality in IPN patients. Cholangitis (p = 0.003; 95% CI 1.598-9.930; aOR 3.983), abdominal compartment syndrome (p = 0.032; 95% CI 1.090-6.967; aOR 2.735), and gastrointestinal/intra-abdominal bleeding (p = 0.009; 95% CI 1.286-5.712; aOR 2.710) were independently associated with the risk of mortality. Upfront open surgical necrosectomy was strongly associated with the risk of mortality (p &lt; 0.001; 95% CI 1.912-7.442; aOR 3.772), whereas endoscopic drainage of pancreatic necrosis (p = 0.018; 95% CI 0.138-0.834; aOR 0.339) and enteral nutrition (p = 0.003; 95% CI 0.143-0.716; aOR 0.320) were found as protective factors. Organ failure, acute cholangitis, and upfront open surgical necrosectomy were the most significant predictors of mortality. Our study confirmed that, even in a subgroup of particularly ill patients such as those with IPN, upfront open surgery should be avoided as much as possible.

The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance.

Investment in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing in Africa over the past year has led to a major increase in the number of sequences that have been generated and used to track the pandemic on the continent, a number that now exceeds 100,000 genomes. Our results show an increase in the number of African countries that are able to sequence domestically and highlight that local sequencing enables faster turnaround times and more-regular routine surveillance. Despite limitations of low testing proportions, findings from this genomic surveillance study underscore the heterogeneous nature of the pandemic and illuminate the distinct dispersal dynamics of variants of concern-particularly Alpha, Beta, Delta, and Omicron-on the continent. Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve while the continent faces many emerging and reemerging infectious disease threats. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century

The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance

INTRODUCTION Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic. RATIONALE We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs). RESULTS Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants. CONCLUSION Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century
