BACKGROUND: Parenteral and enteral nutrition are essential for both growth and development of preterm infants. Based on the results of many studies, the rate of nutritional growth and the amount of substrate delivered parenterally are under debate. OBJECTIVE: The main aim of this study was to assess parenteral nutrition in very and extremely immature preterm infants, i.e. very low birth weight (VLBW, birth weight <1500g) and extremely low birth weight (ELBW, birth weight <1000g) neonates, and to compare the amount of parenterally delivered substrate in our neonatal intensive care unit (NICU) to current German guidelines...

Background: Injury to the common peroneal nerve disrupts the motor control pathway to ankle dorsiflexors and evertors, as well as toe extensors, resulting in pathological gait and foot drop. Direct external compression on the fibular head is the most frequent cause of peroneal nerve impairment and has poor prognosis. Methods and Patients: Here, we report the surgical outcome of 21 patients with foot drop (9 males and 12 females) who underwent nerve transfer procedure of either the superficial peroneal nerve or the tibial nerve fascicles to the motor branch of the tibialis anterior and to the deep peroneal nerve...

BACKGROUND: The vertical vestibulo-ocular reflex (VOR) may be impaired in internuclear ophthalmoplegia (INO) as the medial longitudinal fasciculus (MLF) conveys VOR-signals from the vertical semicircular canals. It has been proposed that signals from the contralesional posterior semicircular canal (PSC) are exclusively transmitted through the MLF, while for the contralesional anterior canal other pathways exist. OBJECTIVE: Here, we aimed to characterize dysfunction in individual canals in INO-patients using the video-head-impulse test (vHIT) and to test the hypothesis of dissociated vertical canal impairment in INO...

Anish Mirchandani, Allen Chen
Patients presenting with a chin-on-chest deformity, or dropped head syndrome (DHS), may have a diagnosis of isolated neck extensor myopathy (INEM). INEM is a diagnosis of exclusion occurring primarily in elderly patients. INEM usually has a benign progression, which may involve the shoulder girdle but does not advance to other muscle groups. Patients without an inflammatory etiology typically experience minimal or no recovery of their symptoms. Dropped head syndrome has various implications on a patient's quality of life and activities of daily living...

We sought to understand why saline drops produce intriguing patterns when drying in the presence of zwitterionic liposomes. Specifically, we would like to comprehend why the nature of such patterns is hierarchically driven by the Hofmeister series. The liposome suspension is made of 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) with alkali metal chlorides. A complexity analysis of the patterns gives a fractal dimension around 1.71, which means that the drying process resembles a DLA mechanism. A physicochemical study, including the determination of zeta potential, molecular dynamics simulations, microrheology, and calorimetry, supports the fact that electrostatic interactions among head groups of phospholipids with alkali cations are the driven forces behind the assembling of the observed structures...

BACKGROUND: Hypotension is a significant risk factor for the development of ischemic complication following revascularization surgery for moyamoya disease (MMD). However, it is currently unknown whether autonomic dysfunction also plays a role. CASE DESCRIPTION: Here we report a case of MMD in which hypotension due to autonomic dysfunction caused postoperative cerebral ischemia. A 30-year-old female patient with MMD had a history of transient right hemiparesis following laughter...

Mole-rats are known to use their protruding, chisel-like incisors to dig underground networks of tunnels, but it remains unknown how these incisors are used to break and displace the soil. Theoretically, different excavation strategies can be used. Mole-rats could either use their head depressor muscles to power scooping motions of the upper incisors (by nose-down head rotations) or the lower incisors (by nose-up head rotations), or their jaw adductors to grab and break the soil after penetrating both sets of incisors into the ground, or a combination of these mechanisms...

BACKGROUND: Cardiovascular complications associated with expensive noninsulin agents for type 2 diabetes are the focus of concern in light of the risk of kidney dysfunction with aging. Head-to-head comparisons are unavailable to guide the choice of new drugs for hyperglycemia in patients with type 2 diabetes, decreased estimated glomerular filtration rate (eGFR) and increased cardiovascular risk. A first approach would be to document current medication choices. METHODS: All prescriptions for 10 151 patients (5623 males/4528 females) with both type 2 diabetes and hypertension seen two or  more times during a 5-year period (2007-12) at Joslin Diabetes Center were evaluated...

Adult horn fly populations were tracked on cattle for 2-week periods before, during and after multiple treatments (every 3-4days) with two repellents in a mineral oil carrier. Cattle were sprayed four times in a two-week period either with 2% geraniol (125ml/cow) or a 15% mixture of short chain fatty acids (C8-C9-C10)(250ml/cow), and there were untreated control cattle. Trials were conducted in California and North Carolina for 3 summers. Short-term fly counts (same day) on treated cattle were reduced by 61-99%, depending on material and trial, and the fatty acid mixture provided better control than geraniol...

Fatty acid oxidation disorders presenting as primary myopathy is relatively rare and also diagnostically challenging. Its association with "dropped head syndrome" is reported till date in single cases of carnitine deficiency and multiple acyl CoA dehydrogenase deficiency (MADD).We studied nineteen cases of primary progressive myopathy confirmed to have fatty acid oxidation defects by Tandem Mass Spectrometry. The detailed clinical, muscle histopathology, tandem mass spectrometry and muscle magnetic resonance imaging (MRI) findings are presented here...

In European countries, wheat occupies the largest crop area with high yielding production. France, a major producer and exporter in Europe, ranks the fifth producer worldwide. Biotic stresses are European farmers' major challenges (fungal and viral diseases, and insect pests) followed by abiotic ones such as drought and grain protein composition. During the last 40 years, 1136 scientific articles on biotech wheat were published by USA followed by China, Australia, Canada, and European Union with the UK. European research focuses on pests and diseases resistances using widely marker-assisted selection (MAS)...

INTRODUCTION: Orthostatic hypotension is defined as a sustained decrease in systolic blood pressure of 20 mm Hg or a decrease in diastolic blood pressure of 10 mm Hg within three minutes of standing compared with blood pressure from the sitting or supine position or by head-up tilt-table testing (1). When sustained blood pressure (BP) drop is after three minutes of upright posture it is called delayed orthostatic hypotension (delayed OH) (2). AIM OF THE STUDY: To detect the incidence of delayed orthostatic hypotension in patients referred to our autonomic lab...

A dispersive liquid–liquid microextraction (DLLME) technique based on a solidification-of-floating-organic-drop (SFOD) procedure was developed for the determination of trace amounts of cadmium (Cd) by using a flame atomic absorption spectrometer (FAAS) fitted with a slotted quartz tube (SQT). The extraction of Cd was achieved by forming a complex with diphenylcarbazone. Parameters affecting the formation of complex and extraction outputs were carefully optimized to obtain high-absorbance signals to achieve lower LODs...

Carlo Valerio Bellieni, Giuseppe Buonocore
Mortazavi's comment (1) on our letter (2) on whether electromagnetic fields (EMF) in incubators are a risk factor for autism contains several points that need to be corrected. First, we did not base our observations just on our previous papers as Mortazavi maintains. In fact, our observations were also based on several more papers about EMF in incubators, including the paper by Calvente et al, which was published in 2017 (3). Second, it is incorrect to write that a very simple intervention, such as changing the infants' sleep position, namely the position of the head and feet, can lead to a significant drop, as big as several orders of magnitude, in the infant's brain exposure (1), because in most incubators EMF levels are similar at all points of the mattress...

American football has both the highest rate of concussion incidences as well as the highest number of concussions of all contact sports due to both the number of athletes and nature of the sport. Recent research has linked concussions with long term health complications such as chronic traumatic encephalopathy and early onset Alzheimer's. Understanding the mechanical characteristics of concussive impacts is critical to help protect athletes from these debilitating diseases and is now possible using helmet-based sensor systems...
