E Ali, M Raghuvanshi
OBJECTIVE: Open upper limb injuries requiring soft reconstruction can pose a dilemma for trauma surgeons when considering the treatment options. The British Orthopaedic Association and British Association of Plastic, Reconstructive and Aesthetic Surgeons Standard for Trauma (BOAST) have addressed the management of severe open lower limb fractures with the creation of the BOAST 4 guidelines. However, no such gold standard exists for the treatment of open injuries of the upper limb. Furthermore, treatment of these injuries is often more difficult and requires complicated strategies...

Pretibial lacerations are a common cause of presentation to accident and emergency departments. The management of these wounds is contentious with a variation in practise between individual institutions. We present the case of a 49-year-old female with a background of pulmonary atresia and associated pulmonary hypertension, who underwent successful outpatient negative pressure wound therapy (NPWT) for three pretibial lacerations. We would propose that this therapy is an effective option for the management of these wounds in independently mobile patients who are at high-risk when under anaesthetic...

Liquefied Petroleum Gas (LPG) cookstoves are considered to be an important solution for mitigating household air pollution; however, their performance has rarely been evaluated. To fill the data and knowledge gaps in this important area, eighty-nine laboratory tests were conducted to quantify efficiencies and pollutant emissions from five commercially available household LPG stoves under different burning conditions. The mean thermal efficiency (± standard deviation) for the tested LPG cookstoves was 51±6%, meeting guidelines for the highest tier level (Tier 4) under the International Organization for Standardization, International Workshop Agreement 11...

Sodium intake is associated with obesity and metabolic disorder in the general population. However, sodium intake is significantly reduced according to the decrease of energy intake in older adults although the prevalence of obesity is higher than younger adults. We evaluate the association of sodium excretion (UNa) with blood pressure, obesity, metabolic disorders, and albuminuria according to age. An observational study using data from the Korean National Health and Nutrition Examination Survey IV-V (2008-2011) was performed (N = 18,146)...

In animals, gas exchange between blood and tissues occurs in narrow vessels, whose diameter is comparable to that of a red blood cell. Red blood cells must deform to squeeze through these narrow vessels, transiently blocking or occluding the vessels they pass through. Although the dynamics of vessel occlusion have been studied extensively, it remains an open question why microvessels need to be so narrow. We study occlusive dynamics within a model microvascular network: the embryonic zebrafish trunk. We show that pressure feedbacks created when red blood cells enter the finest vessels of the trunk act together to uniformly partition red blood cells through the microvasculature...

BACKGROUND: Asphyxia is the most common reason for newborns to fail to make a successful fetal to neonatal transition. There is currently a lack of data evaluating hemodynamic effects of epinephrine during neonatal cardiopulmonary resuscitation. METHODS: Twenty-four newborn piglets were exposed to asphyxia. Thereafter, positive pressure ventilation was commenced for 30 s, followed by chest compressions (CC). Piglets were randomized into three experimental groups: 3:1 compression:ventilation ratio; CC during sustained inflation (SI) at a rate of 90 CC per minute, or CC during SI at a rate of 120 CC per minute...

Prehydrolysate, a dilute solution consisting mainly of pentoses, hexoses, and lesser quantities of organic acids, furfural and phenolics, is generated in the Kraft dissolving pulp process. An obstacle facing the valorization of the solution in hemicellulose biorefineries, by conversion of the sugars into bioproducts such as furfural, is the low sugar concentration. Membrane filtration is typically proposed in several hemicellulose based biorefineries for concentrating the solution, although they are usually generated using different wood species, pretreatment methods, and operating conditions...

CASE: Electronic cigarettes are an increasingly popular and poorly regulated alternative to traditional cigarettes that deliver nicotine and other aerosolized substances to the user via a battery-powered atomizer. We report a case in which an electronic cigarette explosion resulted in a high-pressure injection injury of the finger. CONCLUSION: Explosions involving electronic cigarettes and similar handheld products should be treated as high-pressure injection injuries until proven otherwise...

CASE: An 87-year-old man fell onto a flexed knee and sustained a closed intra-articular patellar dislocation. A closed reduction was performed under intravenous sedation by flexing the knee to 90°, applying an anterior drawer force to the tibia, and applying pressure to the inferior pole of the patella. The day after reduction, weight-bearing was begun in a hinged brace set at 0° to 90°. Full function was regained by 6 weeks postreduction. CONCLUSION: Intra-articular patellar dislocation may present as an unusual cause of a locked knee...

In this study the influence of the addition of dialdehyde starch on the properties of scaffolds based on gelatin and chitosan obtained by the freeze-drying method was investigated. In addition, the adhesion and proliferation of human osteosarcoma SaOS-2 cells on the obtained scaffolds was examined. Chitosan and gelatin were mixed in different weight ratios (75/25, 50/50, 25/75) with 1, 2 and 5 wt% addition of dialdehyde starch. The obtained scaffolds were subjected to mechanical testing, infrared spectroscopy, swelling measurements, low-pressure porosimetry and zeta potential measurement...

Color polymorphisms have long been of evolutionary interest for their diverse roles, including mate choice, predator avoidance, and pollinator attraction. While color variation is often under strong selection, some taxa demonstrate unexpectedly high frequencies of presumed deleterious color forms. Here we show that a genetic variant underlying complete loss of anthocyanin pigmentation has risen to an unexpectedly high frequency of >0.2 in a natural population of the plant Mimulus guttatus. Decreased expression of MYB5 transcription factor is associated with unpigmented morphs...

The relationship between the renin-angiotensin aldosterone system and short-term blood pressure variability has not been well elucidated. Here, we investigated whether blood pressure variability determined by ambulatory blood pressure monitoring differed among patients with primary aldosteronism (PA), renovascular hypertension (RVHT), and essential hypertension (EHT). We examined 25 patients with PA, 28 patients with RVHT, and 18 patients with EHT. Ambulatory blood pressure monitoring was conducted in all patients...

Cardiovascular diseases are the leading cause of death. The underlying pathophysiology is largely contributed by an overactivation of the renin-angiotensin-aldosterone-system (RAAS). Herein, angiotensin II (AngII) is a key mediator not only in blood pressure control and vascular tone regulation, but also involved in inflammation, endothelial dysfunction, atherosclerosis, hypertension and congestive heart failure. Since more than three decades suppression of AngII generation by inhibition of the angiotensin-converting enzyme (ACE) or blockade of the AngII-receptor has shown clinical benefit by reducing hypertension, atherosclerosis and other inflammation-associated cardiovascular diseases...

RATIONALE: Many in-hospital cardiac arrests are precipitated by hypotension, often associated with systemic inflammation. These patients are less likely to be successfully resuscitated and novel approaches to their treatment are needed. OBJECTIVES: To determine if the addition of inhaled nitric oxide (iNO) to hemodynamic-directed cardiopulmonary resuscitation (HD-CPR) would improve short-term survival from cardiac arrest associated with shock and systemic inflammation...

The onset of drainage of liquids from fluid-handling components with a single, circular orifice was evaluated. A component was filled with water, ethylene glycol, or ethyl alcohol and then oriented vertically with its orifice facing downward. The lower end of the component was slowly tilted toward the horizon. No flow occurred until a critical angle of inclination was reached. The onset of drainage was successfully modeled as a balance between the hydrostatic pressure in the bulk liquid and the Laplace pressure of the air-liquid interface within the orifice...
