#1
Martin Balik, Vojtech Matousek, Michal Maly, Tomas Brozek
The occurrence of supraventricular arrhythmias is associated with an unfavourable prognosis in septic shock. Available trials are difficult to apply in sepsis and septic shock patients due to included cohorts, control groups and because "one size does not fit all". The priorities in the critically ill are maintenance of a sinus rhythm and diastolic ventricular filling. The rate control modality should be reserved for chronic AF and in situations when a sinus rhythm is difficult to maintain due to extreme stress conditions resulting from a high dosage of vasoactive agents...

Epilepsy and schizophrenia are common and typical neurological or mental illness respectively, and sometimes they comorbid in the same patients, however the underlying genetic relationship between the two brain diseases is still not fully understood. To investigate the possible genetic contribution to their comorbidity, we performed polygenic risk score (PRS) analyses and genetic correlation estimation so as to identify the overall genetic overlap between the two diseases. The global schizophrenia PRS is strongly associated with schizophrenia phenotype in Hong Kong population (odds ratio = 1...

OBJECTIVE: Deep brain stimulation has been shown to have a significant long-term beneficial effect on motor function. However, whether it affects survival is not clear. In this study, we compared survival rates for Parkinson's disease (PD) patients who underwent deep brain stimulation (DBS) with those who were medically managed. METHODS: A retrospective analysis of Veterans Affairs and Medicare administrative data of veterans with PD who received DBS and were propensity score matched to a cohort of veterans with PD who did not receive DBS between 2007-2013...

OBJECTIVE: The purpose of this study was to investigate how quality of life outcome after bilateral subthalamic nucleus (STN) deep brain stimulation (DBS) in Parkinson's disease (PD) depends on age. METHODS: In this prospective, open-label, multicenter study including 120 PD patients undergoing bilateral STN-DBS, we investigated the PDQuestionnaire-8 (PDQ-8), Unified PD Rating Scale-III, Scales for Outcomes in PD-motor examination, complications, activities of daily living, and levodopa equivalent daily dose preoperatively and at 5 months follow-up...

There is a growing appreciation that child functioning in different domains, levels, or systems are interrelated over time. Here, we investigate links between internalizing symptoms, externalizing problems, and academic attainment during middle childhood and early adolescence, drawing on two large data sets (child: mean age 8.7 at enrolment, n = 5,878; adolescent: mean age 11.7, n = 6,388). Using a 2-year cross-lag design, we test three hypotheses - adjustment erosion, academic incompetence, and shared risk - while also examining the moderating influence of gender...

REVIEW
Ashraf Fayad, Sasha K Shillcutt
PURPOSE: The use of transesophageal echocardiography (TEE) has evolved to include patients undergoing high-risk non-cardiac procedures and patients with significant cardiac disease undergoing non-cardiac surgery. Implementation of basic TEE education in training programs has increased across a broad spectrum of procedures in the perioperative arena. This paper describes the use of perioperative TEE in non-cardiac surgery and provides an overview of the basic TEE examination. PRINCIPAL FINDINGS: Perioperative TEE is used to monitor hemodynamic parameters in non-cardiac procedures where there is a high risk of hemodynamic instability...

The Transantarctic Mountains (TAM) are the world's longest rift shoulder but the source of their high elevation is enigmatic. To discriminate the importance of mechanical vs. thermal sources of support, a 550 km-long transect of magnetotelluric geophysical soundings spanning the central TAM was acquired. These data reveal a lithosphere of high electrical resistivity to at least 150 km depth, implying a cold stable state well into the upper mantle. Here we find that the central TAM most likely are elevated by a non-thermal, flexural cantilever mechanism which is perhaps the most clearly expressed example anywhere...

Leptospirillum ferriphilum plays a major role in acidic, metal rich environments where it represents one of the most prevalent iron oxidizers. These milieus include acid rock and mine drainage as well as biomining operations. Despite its perceived importance, no complete genome sequence of this model species' type strain is available, limiting the possibilities to investigate the strategies and adaptations Leptospirillum ferriphilum(T) applies to survive and compete in its niche. This study presents a complete, circular genome of Leptospirillum ferriphilum(T) DSM 14647 obtained by PacBio SMRT long read sequencing for use as a high quality reference...

OBJECTIVE: Ulcerative colitis (UC) is a dynamic disease with its severity continuously changing over time. We hypothesised that the risk of colorectal neoplasia (CRN) in UC closely follows an actuarial accumulative inflammatory burden, which is inadequately represented by current risk stratification strategies. DESIGN: This was a retrospective single-centre study. Patients with extensive UC who were under colonoscopic surveillance between 2003 and 2012 were studied...

INTRODUCTION: UpToDate is widely used by clinicians worldwide and includes more than 9400 recommendations that apply the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. GRADE guidance warns against strong recommendations when certainty of the evidence is low or very low (discordant recommendations) but has identified five paradigmatic situations in which discordant recommendations may be justified. OBJECTIVES: Our objective was to document the strength of recommendations in UpToDate and assess the frequency and appropriateness of discordant recommendations...

Body size is a key life history trait and knowledge of its mechanistic basis is crucial in life history biology. Such knowledge is accumulating in holometabolous insects, whose growth is characterised and body size affected by moulting. According to the oxygen-dependent induction of moulting (ODIM) hypothesis, moult is induced at a critical mass where oxygen demand of growing tissues overrides the supply that principally grows only at moults. Support for the ODIM hypothesis is controversial partly because of a lack of proper data to explicitly test the hypothesis...

BACKGROUND: The ability of the pulmonary embolism rule-out criteria (PERC) to exclude pulmonary embolism without further testing remains debated outside the USA, especially in the population with suspected pulmonary embolism who have a high prevalence of the condition. Our main objective was to prospectively assess the predictive value of negative PERC to rule out pulmonary embolism among European patients with low implicit clinical probability. METHODS: We did a multicentre, prospective, observational study in 12 emergency departments in France and Belgium...

Age-related macular degeneration (AMD) is the leading cause of irreversible vision loss and blindness in developed nations. AMD is anticipated to affect 196 million people worldwide, by 2020. However, the etiology of this disease remains unknown. Aging, genetic, and environmental influences have generally been implicated as major etiologic factors. We sought to examine the hypothesis that consumption of the 'displacing foods of modern commerce,' which equate to processed, nutrient-deficient and potentially toxic foods, may be the primary and proximate cause of AMD...

This hypothesis suggest that starvation-induced ketosis, which leads to a fundamental biochemical change in the metabolic fuel supply of the brain, is uniquely anxiolytic and rewarding to patients prone to AN. Ketosis can easily be replicated by a unique diet marked by high fat, moderate protein, and very low carbohydrate. This diet, known as a ketogenic diet (KGD) mimics starvation, thus allowing the patient to experience the anxiolytic state of ketosis, and yet avoid the morbidity of starvation.
