Background: Increased whole blood viscosity is associated with increased risk of morbidity and mortality of several life-threatening diseases, including cardiovascular and cerebrovascular disease. The effect of diet on human health has been indicated in many studies, and a health dietary pattern can reduce the incidence of several chronic diseases. Objective: The aim of this systematic review was to assess the effect of diet on blood viscosity and related parameters such as haematocrit (HCT)...

BACKGROUND: The unanticipated difficult airway is a potentially life-threatening event during anaesthesia or acute conditions. An unsuccessfully managed upper airway is associated with serious morbidity and mortality. Several bedside screening tests are used in clinical practice to identify those at high risk of difficult airway. Their accuracy and benefit however, remains unclear. OBJECTIVES: The objective of this review was to characterize and compare the diagnostic accuracy of the Mallampati classification and other commonly used airway examination tests for assessing the physical status of the airway in adult patients with no apparent anatomical airway abnormalities...

OBJECTIVES: This study sought to evaluate the phenotypic and functional expression of an apparent hotspot mutation associated with short QT syndrome (SQTS). BACKGROUND: SQTS is a rare channelopathy associated with a high risk of life-threatening arrhythmias and sudden cardiac death (SCD). METHODS: Probands diagnosed with SQTS and their family members were evaluated clinically and genetically. KCNH2 wild-type (WT) and mutant genes were transiently expressed in HEK293 cells, and currents were recorded using whole-cell patch clamp and action potential (AP) clamp techniques...

A Rahim H Zwayed, Brandon Lucke-Wold
Background: Extradural hematomas (EDH) are considered life threatening in that the risk for brain herniation is significant. The current accepted understanding within the literature is to treat EDH via surgical evacuation of the hematoma. Cases: In this case-series we report 62 cases of EDH managed conservatively without surgical intervention. Inclusion criteria were: Glasgow comma scale score 13-15, extradural hematoma confirmed by CT being less than 40 mm, less than 6 mm of midline shift, and no other surgical lesions present...

The clinical success of chimeric antigen receptor (CAR) T cell therapy for CD19+ B cell malignancies can be limited by acute toxicities and immunoglobulin replacement needs due to B cell aplasia from persistent CAR T cells. Life-threatening complications include cytokine release syndrome and neurologic adverse events, the exact etiologies of which are unclear. To elucidate the underlying toxicity mechanisms and test potentially safer CAR T cells, we developed a mouse model in which human CD19 (hCD19)-specific mouse CAR T cells were adoptively transferred into mice whose normal B cells express a hCD19 transgene at hemizygous levels...

This study examines the evidence of three skeletal markers relating to childhood health that leave permanent observable changes in the adult skeleton. Two are well known to paleopathology, namely Harris lines (HL) and linear enamel hypoplasia (LEH). The third skeletal marker is less commonly used; the permanent changes in the temporal bones, induced by chronic or recurrent infectious middle ear disease (IMED) in childhood. A total of 291 adult skeletons from an urban (n = 109) and a rural (n = 182) cemetery, from the Danish medieval period (1050-1536 CE) were included...

A 66 years old Caucasian woman with pneumococcal meningitis was treated and discharged after an uncomplicated course. Five months later she was readmitted with fever and right side abdominal pain and diagnosed with pneumococcal spondylodiscitis. One year later she was treated for a severe chest X-ray confirmed left lobar pneumonia. Two years later she was diagnosed with a pneumococcal pneumonia in her left lung with septic shock. An immune deficiency screen revealed slightly reduced IgA levels, low IgG2 levels, low IgG3 levels and high IgG1 levels...

RATIONALE: Life-threatening anaphylactic shock is a rare (1 in 1 million) but documented occurrence in response to subcutaneous immunotherapy. Immediate administration of Epinephrine (Epi) is critical to save lives in these situations. The current protocol for systemic reactions in immunotherapy is for the prescribing physician to reassess the dosing and schedule as well as the risk:benefit assessment for the therapy and determine whether or not to proceed. PATIENT CONCERNS: The patient revealed concerns regarding the neurologic sequela sustained after undergoinig life-threatening anaphylactic shock...

The heterozygous PHOX2B gene mutation is related to congenital central hypoventilation syndrome (CCHS). It is characterized by defective autonomous nervous system development leading to inadequate breathing response to hypoxia and hypercapnia, leading to hypoventilation especially during non-REM sleep, but also during waking in the more severe cases. Herein we report a case of sudden death in a 28-day-old child. The mother reported the infant was found lying on her own bed in the prone position. The infant was wearing a romper and lying in her crib without any blanket or other objects...

REVIEW
Anna McFarlin
The term "brief resolved unexplained event" was created to replace "apparent life-threatening event," narrowing the definition and providing evidence-based guidelines for management. The emphasis is placed on using clinical clues to classify patients as low risk or exclude them from the categorization altogether. Infants who meet low-risk classification can be briefly observed in the emergency department and be discharged home. Infants who demonstrate elements suggestive of a specific etiology should be evaluated and treated accordingly...

Familial hemophagocytic lymphohistiocytosis (FHL) type 3 is a life-threatening immune dysregulation syndrome caused by mutations in the UNC13D gene, encoding the munc13-4 protein, which is important for function of cytotoxic lymphocytes. FHL3 accounts for 30-40% of FHL cases, and more than 100 mutations in the UNC13D gene have been described to date. We describe the first case of FHL3 carrying an intragenic duplication of UNC13D, apparently mediated by recombination of Alu elements. NK cell degranulation and munc13-4 protein expression assays are useful for early identification of such mutations, which may be missed by analysis of genomic DNA alone...

BACKGROUND: Preeclampsia is a life-threatening disease in pregnancy, and its complex pathomechanisms are poorly understood. In preeclampsia, lipid metabolism is substantially altered. In late onset preeclampsia, remnant removal disease like lipoprotein profiles have been observed. Lipid apheresis is currently being explored as a possible therapeutic approach to prolong preeclamptic pregnancies. Here, apheresis-induced changes in serum lipid parameters are analyzed in detail and their implications for preeclamptic lipid metabolism are discussed...

BACKGROUND: Delays in receiving adequate care for children suffering from pneumonia can be life threatening and have been described associated with parents' limited education and their difficulties in recognizing the severity of the illness. The "three delays" was a model originally proposed to describe the most common determinants of maternal mortality, but has been adapted to describe delays in the health seeking process for caregivers of children under five. This study aims to explore the caregivers' perceived barriers for seeking and receiving health care services in children under five years old admitted to a referral hospital for community-acquired pneumonia in the Peruvian Amazon Region using the three-delays model framework...

Advancing age is the biggest risk factor for development for the major life-threatening diseases in industrialized nations accounting for >90% of deaths. Alzheimer's dementia (AD) is among the most devastating. Currently approved therapies fail to slow progression of the disease, providing only modest improvements in memory. Recently reported work describes mechanistic studies of J147, a promising therapeutic molecule previously shown to rescue the severe cognitive deficits exhibited by aged, transgenic AD mice...

Lemierre's syndrome is a potentially life-threatening consequence of oropharyngeal and ear infections and often results in critical care admission and even intubation. Due to the multisystem manifestation, multiple teams may initially be involved in the care, some of which may be unfamiliar with the features and usual clinical course. This report describes a case in a 36-year-old woman with the classic features of internal jugular vein thrombosis and septic emboli to the lungs secondary to an oropharyngeal infection...
