This paper presents the experimental validation of a readout circuit for the acquisition, amplification and transmission of extremely weak biopotentials with a focus on electroencephalography (EEG) signals. The device, dubbed CochlEEG, benefits from a low-power design for long-term power autonomy and provides configurable gain and sampling rates to suit the needs of various EEG applications. CochlEEG features high sampling rates, up to 4 kHz, low noise signal acquisitions, support for active electrodes and a potential for Wi Fi data transmission...

Over the past few decades, a growing body of epidemiological studies found the effects of temperature on cardiovascular disease, including the risk for acute myocardial infarction (AMI). Our study aimed to investigate whether there is an association between extremely temperature and acute myocardial infarction hospital admission in Beijng, China. We obtained 81029 AMI cases and daily temperature data from January 1, 2013 to December 31, 2016. We employed a time series design and modeled distributed lag nonlinear model (DLNM) to analyze effects of temperature on daily AMI cases...

Waterborne protozoa (WBP) are important cause of several outbreaks all over the world. The report system of WBP in Africa is weak. More than one third of African countries (21/54) reported WBP with absent reports in the remaining countries (33/54). The top reported WBP were Cryptosporidium, Giardia, FLA and Entamoeba contaminating different African water resources. Other protozoa were less documented even though it is abundant and robust. More than one protozoa were detected in contaminated African water including drinking sources, a prediction index to popular epidemics and real presence of undocumented WBP outbreaks...

Label-free, high-throughput, and efficient separation and enrichment of rare tumor cells, such as circulating tumor cells (CTCs), from untreated whole blood is a challenging task, owing to extremely rare events of CTCs and an enormous amount of blood cells. Current strategies for CTC separation always require pre-processing steps including lysis of blood or labeling of CTCs, leading to loss or damage of CTCs. Here, we report an interfacial viscoelastic microfluidic system for size-selective separation of tumor cells directly from whole blood, without the need of cell labeling and other treatments...

We develop a method for the evaluation of extreme event statistics associated with nonlinear dynamical systems from a small number of samples. From an initial dataset of design points, we formulate a sequential strategy that provides the "next-best" data point (set of parameters) that when evaluated results in improved estimates of the probability density function (pdf) for a scalar quantity of interest. The approach uses Gaussian process regression to perform Bayesian inference on the parameter-to-observation map describing the quantity of interest...

AIM:  No consensus exists regarding the optimal strategy for perioperative thromboprophylaxis in high-risk microsurgical populations. We present our experience with lower extremity free tissue transfer (FTT) in thrombophilic patients and compare outcomes between non-stratified and risk-stratified anticoagulation protocols. METHODS:  Between January 2013 and December 2017, 57 patients with documented thrombophilia underwent FTT for non-traumatic, lower extremity reconstruction by a single surgeon...

PURPOSE: Traumatic dislocation of the mandibular condyle into the middle cranial fossa (DMCCF) is a rare event after maxillofacial trauma. Treatment may be performed with closed or open reduction (with or without craniotomy), and arthroplasty procedures might be necessary for long-standing cases. The aims of this study were to perform an integrative review of traumatic DMCCF cases reported in an electronic database and to report a case in which cerebrospinal fluid leakage occurred after open treatment...

The spectacled flying fox ( Pteropus conspicillatus) is listed as vulnerable to extinction in Australia. The species' restricted population is in decline, putatively attributed to decreasing habitat, climatic extremes, anthropogenic activities, and more recently, mass mortality events associated with tick paralysis and neonatal cleft palate syndrome. Knowledge of fundamental physiologic parameters of the species is limited. To address this knowledge gap, we sampled 50 wild-caught adult spectacled flying foxes in June (winter) in Far North Queensland, Australia...

Beer is the most popular alcoholic beverage in the world by volume consumed, and yields of its main ingredient, barley, decline sharply in periods of extreme drought and heat. Although the frequency and severity of drought and heat extremes increase substantially in range of future climate scenarios by five Earth System Models, the vulnerability of beer supply to such extremes has never been assessed. We couple a process-based crop model (decision support system for agrotechnology transfer) and a global economic model (Global Trade Analysis Project model) to evaluate the effects of concurrent drought and heat extremes projected under a range of future climate scenarios...

Study Design: Level III retrospective cross-sectional study. Purpose: To define and characterize the presentation, symptom duration, and patient/surgical risk factors associated with 'postdecompressive neuropathy (PDN).' Overview of Literature: PDN is characterized by lower extremity radicular pain that is 'different' from pre-surgical radiculopathy or claudication pain. Although it is a common constellation of postoperative symptoms, PDN is incompletely characterized and poorly understood...

Febrile seizures (FS), events associated with a fever in the absence of an intracranial infection, hypoglycaemia, or an acute electrolyte imbalance, occur in children between six months and six years of age. FS are the most common type of convulsions in children. FS can be extremely frightening for parents, even if they are generally harmless for children, making it important to address parental anxiety in the most sensitive manner. The aim of this review was to focus on the management of FS in the pediatric age...

Research has shown that feeling empathy sometimes leads to compassion fatigue and sometimes to compassion satisfaction. In three studies, participants recalled an instance when they felt empathy in order to assess the role time perspective plays in how empathizers perceive the consequences of empathy. Study 1 revealed that college students perceive empathy as having more negative consequences in the short term, but more positive consequences in the long term. Study 2 showed that service industry professionals perceive the consequences of feeling empathy for customers who felt bad as less negative, and the consequences of feeling empathy for people who felt good as less positive, in the long as opposed to the short term...

BACKGROUND: Chronic venous disease (CVD) is extremely common worldwide. The prevalence is increasing with age and is associated with a reduced quality of life, particularly in relation to pain, physical function and mobility. Symptomatic chronic venous insufficiency (CVI) with venous ulcer at its' endpoint, indicates interventional surgery to cure venous reflux therewith promoting wound healing and preventing recurrence. To our knowledge up to now no coherent study has been undertaken in patients with CVI who underwent an open venous surgery concerning complications, venous hemodynamics and perioperative symptomology in one study population...

Minimal change nephrotic syndrome (MCNS) is the most common cause of nephrotic syndrome in children and can also present in adults. Corticosteroids generally induce remission of MCNS, and relapses are common after reduction or discontinuation of corticosteroids. We experienced a rare case of steroid-sensitive MCNS where the patient relapsed after 52 years of remission. The patient was a 61-year-old Japanese male who visited our clinic for an edema of the lower extremities which had already persisted for a few days...

Background: Chronic Myeloid Leukemia (CML) is a myeloproliferative neoplasm related to chromosomal reciprocal translocation t(9;22). Tyrosine kinase inhibitors (TKIs) such as imatinib have drastically revolutionized the course and the prognosis of this hematologic malignancy. As we know, the association pregnancy-CML is an infrequent situation. Also the use of TKI in pregnant women is unsafe with a lack of alternatives and effective therapeutic options. Thus its cessation during gestation puts those patients at high risk of developing blast crisis characterized by poor outcomes...

Violence against women is a disabler of dignity, liberty, and rights of the person, with murder being its extreme form for silencing the individual. Despite psycho-criminological research providing evidence that violence can happen across cultures, sexes, and societies, other findings show that some forms of violence i.e. Intimate Partner Violence (IPV), which involves more frequently women as victims, is not rare in contemporary society. The aim of this study is to analyze the violence against women, and how it escalates up to the point in which it aggravates into femicide...

BACKGROUND: A few studies in high-income countries have investigated the relationship between ambient temperature and/or precipitation and the occurrence of gastroenteritis. In most of the cases, hot temperatures and heavy precipitation events have been related to increases in infections. This is of concern as climate change predictions indicate an increase of those extreme events. Our aim was to evaluate the association between meteorological variables and daily gastroenteritis hospitalizations in Spain for the period 1997-2013...

BACKGROUND: Ehlers-Danlos syndrome is a rare genetic connective tissue disorders, but the vascular type (Type IV) typically poses the greatest risk to patients. We report a case of multiple cranial artery dissection, which was successfully treated with carotid artery stenting. CASE DESCRIPTION: A 50-year-old woman presented with recurrent severe headaches caused by bilateral vertebral artery dissections that were treated conservatively at our hospital. However, she developed right cervical pain and dizziness at 3 days after admission, and a magnetic resonance angiogram revealed dissection of the right internal carotid artery...

It is shown that the conserved charges on the event horizon and the Cauchy horizon associated with scalar perturbations on extremal black holes are externally measurable from null infinity. This suggests that these charges have the potential to serve as an observational signature. The proof of this result is based on obtaining precise late-time asymptotics for the radiation field of outgoing perturbations.

Synchronous phyllodes tumour and invasive lobular carcinoma is an extremely rare event. We report these concurrent diagnoses in a patient observed in an ipsilateral breast, suspected due to breast risk factors (family history and lobular carcinoma in situ ) and the presence of malignant phyllodes. Screening breast magnetic resonance imaging was able to identify the carcinoma which was occult in other imaging. An understanding of the possibility of dual diagnoses may lead to additional investigations for its identification...
