Serratia marcescens is a member of the genus Serratia, which is a part of the family Enterobacteriaceae. Currently 14 species ofSerratia are recognized within the genus, eight of which are associated with human infection. Of the eight species implicated in clinical infection S. marcescens, S. liquefaciens and S. odorifera are best known. Of all Serratia species, S. marcescens is the most common clinical isolate and the most important human pathogen.
S. marcescens is credited with a long fanatical history dating back to antiquity, when, because of its ability to produce a red pigment it was described as having ‘masqueraded’ as blood . Early in this century, this distinctive red pigmentation of S. marcescens, combined with an apparent low level of virulence, led to its use as a biological marker of infection. Consequently, S. marcescens was used in a number of classic bacterial transmission experiments, which led to improved understanding of the epidemiology of infection. Under more controversial settings, S. marcescens was also used by the US military in a series of biological warfare test experiments conducted on the general population . From 1960 onwards, however, non-pigmented isolates of S. marcescenspredominated over pigmented strains in the clinical setting and were increasingly implicated in healthcare-associated infection particularly among compromised patients.

Americas region is declared the world’s first to eliminate rubella
The Americas region has become the first in the world to be declared free of endemic transmission of rubella, a contagious viral disease that can cause multiple birth defects as well as fetal death when contracted by women during pregnancy.
This achievement culminates a 15-year effort that involved widespread administration of the vaccine against measles, mumps and rubella (MMR) throughout the Western Hemisphere. The announcement comes as 45 countries and territories of the Americas are participating in the 13th annual Vaccination Week in the Americas (April 25 to May 2).

Researchers closer to being able to change blood types
What do you do when a patient needs a blood transfusion but you don’t have their blood type in the blood bank? It’s a problem that scientists have been trying to solve for years but haven’t been able to find an economic solution – until now.
University of British Columbia chemists and scientists in the Centre for Blood Research have created an enzyme that could potentially solve this problem. The enzyme works by snipping off the sugars, also known as antigens, found in Type A and Type B blood, making it more like Type O. Type O blood is known as the universal donor and can be given to patients of all blood types.

Woman with Hypomagnesemia and Hypocalcemia
CASE: A 71-year-old woman was referred to the endocrinology clinic after several years of unresolved hypomagnesemia that required numerous hospital admissions to receive intravenous magnesium. She previously presented with palpitations on 3 occasions, and once with diarrhea and vomiting. The blood tests on all 4 presentations demonstrated severe hypomagnesemia. Her medical history included type 2 diabetes mellitus and hiatal hernia. Her regular medications included simvastatin, esomeprazole, verapamil, pioglitazone, gliclazide, metformin, and calcium, magnesium, and vitamin D supplementation. Clinical examination in the endocrinology clinic was unremarkable, and no abnormality was demonstrated on electrocardiogram. An echocardiogram was normal.

HIV home test kit
An early diagnosis allows people to get treatment quickly and can prevent serious complications. And individuals successfully treated for HIV are less likely to pass the infection on. This new "do-it-yourself" test is made by company Bio Sure UK and can be bought online.
It works in a similar way to a pregnancy test, measuring levels of antibodies - proteins made in response to the virus - in a person's blood. The device analyses a small droplet of blood, taken from the finger-tip using a lancet. Two purple lines appear if it is positive. The company recommends attending sexual health clinics for advice and further blood tests if both lines appear.

Molecular Link between Lipid Metabolism and Energy Homeostasis
New genes predisposing to low HDL-cholesterol level were searched using genome-wide association analysis in Finnish individuals with extremely low or high HDL-cholesterol. Several new genes predisposing to low HDL-cholesterol were discovered, of which many were known to be associated with immune system and inflammatory reaction of the body, but their role in cholesterol metabolism has not previously been characterized. Some of the subjects appeared to be genetically more prone to inflammation than others, especially in the blood and adipose tissue. The more inflammation inducing genetic variants one had, the stronger was the inflammatory state of the body, especially in blood and adipose tissue, and the lower the HDL-cholesterol level. The inflammation may block the transport of cholesterol from vessel walls to circulation leading to lower HDL-cholesterol levels in the circulation.

Interferences from blood collection tube components on clinical chemistry assays
Improper design or use of blood collection devices can adversely affect the accuracy of laboratory test results. Vascular access devices, such as catheters and needles, exert shear forces during blood flow, which creates a predisposition to cell lysis. Components from blood collection tubes, such as stoppers, lubricants, surfactants, and separator gels, can leach into specimens and/or adsorb analytes from a specimen; special tube additives may also alter analyte stability. Because of these interactions with blood specimens, blood collection devices are a potential source of pre-analytical error in laboratory testing. Accurate laboratory testing requires an understanding of the complex interactions between collection devices and blood specimens. Manufacturers, vendors, and clinical laboratorians must consider the pre-analytical challenges in laboratory testing. Although other authors have described the effects of endogenous substances on clinical assay results, the effects/impact of blood collection tube additives and components have not been well systematically described or explained. This review aims to identify and describe blood collection tube additives and their components and the strategies used to minimize their effects on clinical chemistry assays.

Synovial Fluid Analyses, Synovial Biopsy and Synovial Pathology
Analysis of synovial fluid and synovial tissue obtained from diseased joints provides important diagnostic information in specific clinical settings, and is valuable in addressing a spectrum of research questions aimed at enhancing our understanding of the pathogenesis and mechanisms of rheumatic diseases. Many peripheral joints are readily accessible to sampling of both synovial fluid effusions and synovial tissue, although the knee is the most frequently sampled joint. The techniques used to obtain and analyze synovial fluid and tissue samples are discussed in this article.

Reference Intervals and RCV
For the laboratory medicine, it's critical to understand difference between Reference Interval (RI) and Biological variation (BV). Westgard is pleased to have a guest essay where the most commonly-asked-questions about both topics are answered.
The reference intervals as well as the components of biological variation can together play an important role in medical laboratory to notify doctors about changes in patient status. Therefore, in our opinion the future laboratory information system should not only concerned on the significant changes of patient result compared to the reference interval but also to utilise different indices of biological variation so it can compare the current test result with the previous one (expressed as RCV value).

Procalcitonin or C-reactive protein as infection markers
Although the clinical application of procalcitonin (PCT) as an infection marker in patients with impaired renal function (estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m2) has been increasing recently, it is unclear whether PCT is more accurate than C-reactive protein (CRP). We investigated the clinical value of CRP and PCT based on renal function.
From November 2008 to July 2011, a total of 493 patients who simultaneously underwent CRP and PCT tests were enrolled. The area under the receiver operating characteristic (ROC) curve and characteristics of both markers were analyzed according to infection severity and renal function.
In patients with impaired renal function, the area under the ROC curve was 0.876 for CRP and 0.876 for PCT. In patients with infection, CRP levels differed depending on whether the infection was localized, septic, or severely septic, whereas PCT levels were higher in patients with severe sepsis or septic shock. In patients without infection, CRP did not correlate with eGFR, while PCT was negatively correlated with eGFR.
This study demonstrates that CRP is accurate for predicting infection in patients with impaired renal function. The study suggests that in spite of its higher cost, PCT is not superior to CRP as an infection marker interms of diagnostic value

Can healthy people benefit from health apps?
A health app is a piece of smartphone software that purports to offer the user some health benefit. Many of these apps are aimed at people with diagnoses; for example, they teach the correct use of an asthma inhaler or collect blood pressure results by syncing wirelessly with a blood pressure monitor. But many are aimed at people with no diagnosis: for example, apps that allow users to track their calorie intake and exercise, or even their sleep patterns.
Some apps have the potential to encourage healthier habits and are accessible to most people, writes Iltifat Husain, but Des Spence notes the lack of any evidence of effectiveness and the potential for encouraging unnecessary anxiety.

Overview of Intestinal Protozoan Infections
The most important intestinal protozoan pathogens are Entamoeba histolytica, Cryptosporidium sp, Giardia intestinalis (lamblia), Cystoisospora (Isospora) belli, Cyclospora cayetanensis, and members of the phylum Microsporidia. Multiple pathogenic parasites and nonpathogenic commensal organisms may be present in the intestine at the same time.
Intestinal protozoa are spread by the fecal-oral route, so infections are widespread in areas with inadequate sanitation and water treatment. They are also common in the US in settings where fecal incontinence and poor hygiene prevail, as occur in mental institutions and day care centers. Occasionally, large waterborne outbreaks of intestinal protozoan infection have occurred in the US (eg, the massive waterborne Cryptosporidium outbreak in Milwaukee in 1993). Some GI protozoa are spread sexually, especially with practices involving oral-anal contact, and several protozoan species cause severe opportunistic infections in patients with AIDS.

Prolymphocytic leukemias
T- and B-cell subtypes of prolymphocytic leukemia (PLL) are rare, aggressive lymphoid malignancies with characteristic morphologic, immunophenotypic, cytogenetic, and molecular features. Recent studies have highlighted the role of specific oncogenes, such as TCL-1, MTCP-1, and ATM in the case of T-cell and TP53 mutations in the case of B-cell prolymphocytic leukemia. Despite the advances in the understanding of the biology of these conditions, the prognosis for these patients remains poor with short survival and no curative therapy. The advent of monoclonal antibodies has improved treatment options. Currently, the best treatment for T-PLL is intravenous alemtuzumab, which has resulted in very high response rates of more than 90% when given as first-line treatment and a significant improvement in survival. Consolidation of remissions with autologous or allogeneic stem cell transplantation further prolongs survival, and the latter may offer potential cure. In B-PLL, rituximab-based combination chemo-immunotherapy is effective in fitter patients. TP53 abnormalities are common and, as for chronic lymphocytic leukemia, these patients should be managed using an alemtuzumab-based therapy. The role of allogeneic transplant with nonmyeloablative conditioning needs to be explored further in both T- and B-cell PLL to broaden the patient eligibility for what may be a curative treatment.

Smartphone-based POCT in cytology and histopathology
A smartphone-based device developed by Harvard Medical School investigators at Massachusetts General Hospital could bring rapid, accurate molecular diagnosis of cancer and other diseases to locations lacking the latest medical technology. The device uses technology for making holograms to collect detailed microscopic images for digital analysis of the molecular composition of cells and tissues.
The D3 (digital diffraction diagnosis) system features an imaging module with a battery-powered LED light clipped onto a standard smartphone. It records high-resolution imaging data with its camera. With a much larger field of view than traditional microscopy, the D3 system is capable of recording data on more than 100,000 cells from a blood or tissue sample in a single image. The data can then be transmitted for analysis to a remote graphic-processing server via a secure, encrypted cloud service. The results can be rapidly returned to the point of care for viewing.

Free Webinar: Preanalytical Errors in Venous Blood Sampling
Venous blood sampling is the most common invasive procedure in healthcare. A recent investigation performed by the Working group for Preanalytical Phase (WG-PRE) of the European Federation for Clinical Chemistry and Laboratory Medicine (EFLM) has shown that blood sampling in Europe is performed by different professions with significantly different levels of education, background, competence and skills.
Surprisingly, in some countries, even administrative staff is involved in venous blood sampling, with little if any education about the procedure and how it can affect the quality of the sample and patient results. Moreover, while guidelines for venous blood sampling are available (CLSI H3-A6), it has been shown that those guidelines are neither implemented worldwide, nor complied with adequately. Such low level of compliance clearly puts patients at risk. Any deviation from the recommended procedure can affect either the quality of the sample or patient well-being.

Morphine test printed on paper
VTT is the first in the world to have developed a drug test printed on paper. VTT used antibodies – produced by methods of molecular biology – as morphine sensing molecules when creating this printing technology-based morphine test. Using printing technology to manufacture rapid tests enables high production volumes and low production costs.
A paper-based test enables a rapid analysis of whether a compound – in this case, morphine – is present in a given sample. Possible future applications of the developed test include drug testing at workplaces and in connection with traffic control.
This method, developed by VTT Technical Research Centre of Finland Ltd, provides several advantages, such as high production volumes, low material costs and disposability as well as design freedom based on bendability and foldability of paper.

Springtime in the lab
Once upon a time, I was a science student. Once upon a time, test tubes were standard equipment in science class. Be it for Chemistry or Biology. They used to be filled with coloured chemicals, held over bunsen burners and stood in their well stained wooden racks as we conducted our experiments. Nowadays, they are the new vases. I spotted them around the place and when I saw them on Urban Outfitters, that sealed the deal. The forgotten science student merged with the artsy side of me, and I went on a hunt for more floral beauty. In a tube.

Haemoglobin Disorders
Haemoglobin disorders or haemoglobinopathies are a group of conditions affecting human blood – more specifically an important substance or protein called haemoglobin contained in the red blood cells, hence the name haemoglobin disorders or haemoglobinopathies.
Haemoglobin is a protein that consists of the alpha (α) and beta (β) parts or chains and which are in turn produced by the α-globin genes and β-globin genes respectively. Hence the diseases caused by haemoglobin abnormality either with regards to its production or its structure are divided into α-chain diseases (or α-globin gene) diseases and β-chain (β-globin gene) diseases. These genes are found on chromosomes 16 and 11 respectively.

Neutrophils: Between Host Defence, Immune Modulation, and Tissue Injury
Neutrophils, the most abundant human immune cells, are rapidly recruited to sites of infection, where they fulfill their life-saving antimicrobial functions. While traditionally regarded as short-lived phagocytes, recent findings on long-term survival, neutrophil extracellular trap (NET) formation, heterogeneity and plasticity, suppressive functions, and tissue injury have expanded our understanding of their diverse role in infection and inflammation. This review summarises our current understanding of neutrophils in host-pathogen interactions and disease involvement, illustrating the versatility and plasticity of the neutrophil, moving between host defence, immune modulation, and tissue damage.

Unsafe medical care is a major source of disabling injuries and death throughout the world. The failure to notify, follow up, and action critical results, which signify life threatening situations, is of particular concern and may cause avoidable morbidity and mortality. International accreditation standards require pathology laboratories to have a system for the timely and reliable communication of critical results to clinical personnel responsible for patient care. In response, various practices and a number of different terminologies have been described in the literature. Increased attention to patient safety standards and multinational surveys, however, highlighted shortcomings and inefficiencies in existing communication systems. These failures and variations in practice call for clear guidance and harmonization of approaches in order to improve communications and to provide safer patient care. The objectives of this review are to create a harmonized terminology and to learn from international practices by systematically reviewing the best available evidence on existing approaches. Based on literature review findings we highlight key areas where harmonization is necessary and feasible and offer a conceptual framework and methods for designing better and more evidence-based systems for the timely notification of laboratory results that represent potential patient safety hazards.

Bacterial Meningitis
CASE: A 28-year-old woman was seen in the emergency department of this hospital because of headache, fever, and a rash. The patient had been well until the morning of the day of admission, when she awoke with a severe generalized headache. The headache worsened with movement, was not relieved by acetaminophen or ibuprofen, and was accompanied by nausea and one episode of nonbloody, nonbilious emesis. The patient returned to sleep and awoke again several hours later with diffuse myalgias; her temperature was 37.7°C. At that time, she also noted a rash on her abdomen, chest, and right arm; the lesions were small, red, flat, nonpruritic, and nonpainful. She described these symptoms to her father, a physician, who advised her to go to the emergency department of this hospital.
