Bloodstream infections are frequent in children admitted to the hospital for severe febrile illness in sub-Saharan Africa.Ongoing blood culture surveillance at Kisantu Hospital showed non-typhoidal Salmonella (NTS) as the first cause of bloodstream infections in children. Bloodstream infections have a high case fatality (15 - 20%). Outcome of bloodstream infections is dependent on timely diagnosis and treatment. However, observations at Kisantu Hospital showed that many children arrive late and die early after admission. By interviewing caregivers of severely ill children admitted to Kisantu Hospital, the investigators aim to study their health itinerary, i.e. the sequence of all actions of health care seeking and care provision between the onset of febrile illness and the admission at the hospital. The investigators aim to assess the health itinerary according to the "three delays" model. The three delays model studies delays and practices at the level of health care seeking, of transport and of start of antibiotic treatment.10 Visits to referring health centers will provide complementary information about diagnosis, treatment and referral practices. In hospital follow-up will allow to assess the outcome according to the duration of health itinerary. The results of routine laboratory tests upon hospital admission will allow to stratify the health itinerary according to fever etiology. The results of this study will allow to understand the duration of the health itinerary, its possible association with case-fatality, and factors explaining for delays at every level. This information is expected to orient local health policy makers towards interventions shortening the duration of the health itinerary and in that case improve and monitor the referral system. In addition, the study results are expected to orient towards further research to understand health seeking behavior (i.e. focus-group discussions and community-based studies).

To depict the incidence, outcomes and standards of care (SoC) of adenovirus (AdV) infections and associated practice patterns in allogeneic hematopoietic cell transplant recipients. It is expected that participating centers will be in the United Kingdom, France, Spain, Germany, and Italy.

Based on barriers identified in a systematic literature search, a self-report questionnaire called "BIOTICA" has been developed by the research team to assess medication adherence barriers to oral AB. The purpose of the BIOTICA-questionnaire is to detect individual barriers that prevent the optimal intake of oral AB and thus, lead to inadequate adherence or persistence to the regimen. A study is now needed to establish construct validity. Correlation between the answers to the BIOTICA-questionnaire and the electronically monitored intake of the oral AB will be analyzed in the general population.

The study aims to evaluate the prognostic value of alveolar and blood NETosis in patients under mechanical ventilation and treated for an acute low-respiratory tract infection. The main outcome is the occurrence of an acute respiratory distress syndrome (ARDS) according to the Berlin definition.

Different mechanisms have been proposed to explain the pathophysiology of chronic staphylococcal BJI, including biofilm formation and the ability of staphylococci to be internalized and to survive within cells. The intracellular localization of staphylococci is well documented by in vitro studies, however, few studies have shown the presence of intracellular staphylococci in clinical specimens from patients with BJI. The aim of the CRISBO study is to document the clinical relevance of intracellular staphylococci in the context of BJI. Immunostaining targeting staphylococci and components will be carried out on tissue samples taken from patients with BJI during their treatment (samples similar to those used for routine diagnosis in pathology). Our objectives are to identify whether intracellular staphylococci are observable in these samples and if so, in which cell type (s) are they housed.

A retrospective analysis was performed to determine the prevalence of multidrug- resistant organisms infection in ICU from October 2017 to October 2019. Non-MDRO patients were selected by random sampling in a ratio of 1:1 to the final MDRO group during the same period , and select the risk factors of infection with multi-drug resistant bacteria by comparing the two groups. Randomly select 30% of the sample size as the validation set, and the remaining 70% for the training set to establish a model. Using multi-factor Logistic regression, decision tree classification, artificial neural network, support vector machine, Bayesian network Method to establish risk assessment system for multidrug-resistant organisms infection respectively.Using validation set data to calculate the area under the ROC curve (AUC) and sensitivity, specificity of models and comparing the prediction accuracy of several models. Finally, choose a more suitable risk assessment system for multidrug-resistant organisms infection. Predict the patient's infection risk level according to the best risk assessment system and develop a low-to-high intervention plan.

The investigators aim to develop expert consensus statements on infection control management of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in intensive care units (ICU).

Surgical site infections (SSI) constitute an important health concern in low and middle income countries, leading to prolonged hospital stay and increased costs. Previous studies indicate that in Africa up to 1/3 of patients undergoing surgery may be affected by a postoperative infection. The development and implementation of context-specific SSI prevention guidelines is important to reduce this complication. To deploy efficient context-specific measures, data on epidemiology and microbiology of these infections are needed. This means to adapt the prevention measures to the context-specific risk factors for surgical site infections in resource-limited settings, and to give locally adapted recommendations on antimicrobial therapy based on local resistance patterns. However, data in this respect are scarce in low and middle income countries. This present study will contribute to the needed epidemiology and microbiology data on SSI in Cameroon. It will be carried out as a prospective cohort study at the Mbouo Protestant hospital in the West Region of Cameroon. The incidence, microbial spectrum and respective antimicrobial resistance of SSI as well as the risk factors of SSI will be systematically investigated. The study will include 300 patients at the Hôpital Protestant de Mbouo (HPM) who underwent surgery and gave their informed consent for inclusion, the timeframe is 04/2021 - 11/2021. An active SSI surveillance system will be put in place for 30 postoperative days to diagnose SSI. Expected outcomes: The incidence of SSI is likely to be higher than 10%. Concerning risk factors, preoperative bodywashing and perioperative antibioprophylaxis is expected to be protective against SSI. Up to 1/3 of SSI are expected to occur after hospital discharge. For the microbial spectrum, a high proportion of Staphylococcus aureus is likely to be found. For the antimicrobial resistance no estimation can be give as data is non-existent in that region from the literature.
