Despite delayed bacteremia clearance, targeted antibiotic therapy plus anticoagulation usually provide clinical improvement and a low 30-day mortality rate. BACKGROUND Cryptococcal Meningitis (CM) is estimated to cause 181,000 deaths annually; with the majority occurring in Sub Saharan Africa. Flucytosine is recommended by the World Health Organization as part of the treatment for CM. Widespread use of flucytosine could reduce mortality in hospital by as much as 40% compared to the standard of care, yet due to market failure quality assured flucytosine remains unregistered and largely inaccessible throughout Africa. METHODS The recently established South African flucytosine clinical access programme is an attempt to address market failure which led to a lack of public-sector access to flucytosine for cryptococcal meningitis, by making the medicine freely available to tertiary hospitals in South Africa. RESULTS Between November 2018 and September 2019, 327 CM patients received flucytosine through this programme, with efforts to support sustainable national scale up presently ongoing. We describe why this programme was needed, its catalytic potential, what is still required to ensure widespread access to flucytosine, and observation from this experience that may have wider relevance. CONCLUSIONS The South African Flucytosine Access Programme illustrates how access programmes may be one part of the solution to addressing the vicious cycle of perceived low demand, limiting manufacturer interest in specific product markets. We report in this manuscript what is known about the protein makeup of a selection of biological fluids in the domestic dog. The samples we review - amniotic and allantoic fluid, seminal fluid, saliva, bile, synovial fluid, tears - are still very poorly characterized in this species. For some of them we can present results from our own, mainly unpublished experiments. SIGNIFICANCE The dog is one of the most widespread companion animals, and also of medical relevance as model species for some human diseases. Still, investigation of body fluids other than serum and urine is not so commonly undertaken, although - like in humans - also these sample types may have potential for diagnostic purposes. We compile published data about proteomes of fetal fluids, seminal plasma, saliva, bile, synovial fluid and tears, enriched by some yet unpublished data of our own (proteins of amniotic and allantoic fluid, tears). Closing gaps in our knowledge on dog proteins will further our understanding of (patho)physiological processes. Renal cell carcinoma (RCC) is one of the most lethal type of tumors and is twice more frequent in men than in women. Initial symptoms are unspecific and belated thus increasing mortality. Moreover, current diagnostic and monitoring tools are harmful for the patient and unspecific in low-grade tumors. Therefore, novel minimally-invasive markers are needed to diagnose and monitor RCC patients. Urine represents the ideal sample source of non-invasive biomarkers for RCC. In our study we aimed to identify a urine metabolomic profile characteristic of RCC patients with diagnostic purposes and also to identify a profile with prognostic value. By an UPLC-Q-ToF MS untargeted metabolomic analysis, we compared the metabolomic profile of 23 RCC patients (14 clear cell RCC and 9 papillary RCC) before surgery and that of 23 healthy controls. Additionally, for the first time, we compared the metabolomic profile of these RCC patients pre-nephrectomy and 3 months and one year post-nephrectomy. We identified the dysregulated midentified urine p-cresol glucuronide as potential diagnostic marker for RCC and isobutyryl-l-carnitine and l-proline betaine as potential prognostic markers. When confirmed in an independent cohort of RCC patients, these markers may improve the diagnosis and monitoring of RCC patients thus reducing current harmful diagnostic procedures. SIGNIFICANCE The high-radiation dose of current imaging techniques available to diagnose and monitor renal cell carcinoma (RCC) are harmful for the patient and unspecific in low-grade tumors. Our untargeted metabolomic analysis carried out in urine samples from RCC patients and healthy individual reveals p-cresol glucuronide as potential diagnostic marker for RCC. Additionally, the analysis of RCC urine samples one year post-nephrectomy reveals isobutyryl-l-carnitine and l-proline betaine as potential prognostic markers. These novel non-invasive urine biomarkers may improve RCC management thus reducing the use of current harmful diagnostic techniques. Chronic inflammation enhances the detrimental role of dyslipidaemia during atherogenesis. Statins are among the most effective anti-atherosclerotic medications, being able to impact on both cardiovascular morbidity and mortality. Although these molecules have been first described as lipid-lowering medications, several lines of evidence suggest additional benefits through their "pleiotropic" anti-atherosclerotic activities. Specifically, statins can modulate vascular atherosclerotic inflammation by directly improving functions of endothelial cells, vascular smooth muscle cells, platelets, and immune cells. Here, we discuss basic and clinical evidence to provide an update on the molecular mechanisms underlying the protective anti-inflammatory role of statins in atherogenesis. Humans have a natural tendency to treat regularities (what people often do) as norms (what people ought to do). This tendency to move from is to ought introduces bias into our social reasoning because nonconformity to regularities is treated as wrong rather than uncommon. How then can children distinguish norms and regularities? This study investigated whether children use others' distinct reactions to violations of norms and regularities to distinguish the two. Children (103 4- to 8-year-olds) observed a group of demonstrators consistently use one pathway of a novel apparatus, establishing it as the conforming pathway. Then, an additional demonstrator used an alternative (i.e., violating) pathway while bystanders reacted to the violation. In the Norm condition (n = 48) bystanders were visibly irritated and disapproving of the violation, whereas in the Regularity condition (n = 55) bystanders were surprised or confused but ultimately accepting of the violation. selleck products Children then completed three tasks in which they used the apparatus themselves, observed a puppet using the violating pathway, and evaluated the wrongness of using the violating pathway on a Likert scale.
