Advances in the rescue chain and first aid of polytrauma patients, which have consequently increased their chance of survival, have led to an increase in demands for rehabilitation. However, there is still a large hole in the continuity of rehabilitation between acute patient care and in-patient rehabilitation, the so-called "rehab-hole". The consequences are untapped rehabilitation potential, loss of strength, endurance and motivation as well as impairment of function of the patient.Based on the phase model of neurological/neurosurgical rehabilitation, we propose a step model for the rehabilitation of polytrauma patients that ensures an uninterrupted chain of rehabilitation...

Huntington's disease (HD) is a neurodegenerative disorder whose major symptoms include progressive motor and cognitive dysfunction. Cognitive decline is a critical quality of life concern for HD patients and families. The enzyme histone deacetylase 3 (HDAC3) appears to be important in HD pathology by negatively regulating genes involved in cognitive functions. Furthermore, HDAC3 has been implicated in the aberrant transcriptional patterns that help cause disease symptoms in HD mice. HDAC3 also helps fuel CAG repeat expansions in human cells, suggesting that HDAC3 may power striatal expansions in the HTT gene thought to drive disease progression...

BACKGROUND AND OBJECTIVE: To evaluate the role of early focal laser photocoagulation in acute central serous chorioretinopathy (CSC). PATIENTS AND METHODS: A total of 58 eyes with acute naïve CSC (less than 2 months' duration) with focal leak on fundus fluorescein angiography (FFA) were randomized into either a laser or a sham laser group. Eyes with chronic CSC and subfoveal leak were excluded. Visual acuity assessment, microperimetry, optical coherence tomography, and FFA were done at baseline, 1 month (minus FFA), 3 months, and 6 months after treatment...

Monozygotic twins with discordant karyotypes for trisomy 13 are rare. We report a case of a spontaneously conceived pregnancy who presented with first-trimester ultrasound finding of umbilical cord cyst and increased nuchal translucency in Twin A and no abnormalities in Twin B. Amniocentesis revealed 47,XY,+13 karyotype in Twin A and 46,XY karyotype in Twin B. Selective fetal reduction was performed for Twin A. Twin B was delivered at 32 weeks gestation with normal phenotype. Peripheral blood karyotype revealed 15% mosaicism for trisomy 13 and skin fibroblast revealed 46,XY karyotype...

REVIEW
Jessica L Unick, Christine A Pellegrini, Kathryn E Demos, Leah Dorfman
PURPOSE OF REVIEW: There is a large variability in response to behavioral weight loss (WL) programs. Reducing rates of obesity and diabetes may require more individuals to achieve clinically significant WL post-treatment. Given that WL within the first 1-2 months of a WL program is associated with long-term WL, it may be possible to improve treatment outcomes by identifying and providing additional intervention to those with poor initial success (i.e., "early non-responders"). We review the current literature regarding early non-response to WL programs and discuss how adaptive interventions can be leveraged as a strategy to "rescue" early non-responders...

Tubulointerstitial fibrosis (TIF) is a prominent factor in the progression of chronic kidney disease (CKD) regardless of etiology. ErbB4 expression levels were inversely correlated to renal fibrosis in human fibrotic kidneys. In both unilateral ureteral obstruction (UUO) and ischemia reperfusion injury followed by uninephrectomy (IRI/UNx) mouse models, expression levels of ErbB4 were elevated in the early stage of renal injury. Using mice with global ErbB4 deletion except for transgenic rescue in cardiac tissue (ErbB4-/-ht+), we determined that UUO induced similar injury in proximal tubules compared to wild-type mice but more severe injury in distal nephrons...

The meiotic functions of Emi2, an inhibitor of the APC/C complex, have been best characterized in oocytes where it mediates metaphase II arrest as a component of the cytostatic factor. We generated knockout mice to determine the in vivo functions of Emi2-in particular, its functions in the testis, where Emi2 is expressed at high levels. Male and female Emi2 knockout mice are viable but sterile, indicating that Emi2 is essential for meiosis but dispensable for embryonic development and mitotic cell divisions...

Increased fatty acid β-oxidation is essential for early post-germinative growth in seedlings, but high levels of H2 O2 produced by β-oxidation can induce oxidative stress. Whether and how catalase (CAT) functions in fine-tuning H2 O2 homeostasis during seedling growth remain unclear. Here, we report that CAT2 functions in early seedling growth. Compared to the wild type, the cat2-1 mutant, with elevated H2 O2 levels, exhibited reduced root elongation on sucrose (Suc)-free medium, mimicking soils without exogenous sugar supply...

PROBLEM: The aim of this concept analysis was to clarify failure to rescure as a nurse-sensitive indicator. Although the concept of failure to rescue as a nurse-sensitive outcome has appeared in the nursing literature for over a decade, conceptual clarity is needed to address its variable and ambiguous use in health care. METHODS: Walker and Avant's eight-stage method of concept analysis was used to explore the concept of failure to rescue in nursing practice. Twenty-one papers were retrieved from Cumulative Index of Nursing and Allied Health Literature (CINAHL) and MEDLINE databases and selected for review and synthesis...

Neuronal necrosis occurs during early phase of ischemic insult. However, our knowledge of neuronal necrosis is still inadequate. To study the mechanism of neuronal necrosis, we previously established a Drosophila genetic model of neuronal necrosis by calcium overloading through expression of a constitutively opened cation channel mutant. Here, we performed further genetic screens and identified a suppressor of neuronal necrosis, CG17259, which encodes a seryl-tRNA synthetase. We found that loss-of-function (LOF) CG17259 activated eIF2α phosphorylation and subsequent up-regulation of chaperons (Hsp26 and Hsp27) and autophagy...

Sensorineural hearing loss is commonly caused by damage to cochlear sensory hair cells. Coinciding with hair cell degeneration, the peripheral fibres of type I spiral ganglion neurons (SGNs) that normally form synaptic connections with the inner hair cell gradually degenerate. We examined the time course of these degenerative changes in type I SGNs and their satellite Schwann cells at the ultrastructural level in guinea pigs at 2, 6, and 12 weeks following aminoglycoside-induced hearing loss. Degeneration of the peripheral fibres occurred prior to the degeneration of the type I SGN soma and was characterised by shrinkage of the fibre followed by retraction of the axoplasm, often leaving a normal myelin lumen devoid of axoplasmic content...

HIV-associated neurocognitive disorder (HAND) affects approximately half of HIV-infected patients. Loss of synaptic connections is a hallmark of many neurocognitive disorders, including HAND. The HIV-1 protein transactivator of transcription (Tat) disrupts synaptic connections both in vitro and in vivo and has been linked to impaired neurocognitive function in humans. In vitro studies have shown that ifenprodil, an antagonist selective for GluN2B-containing NMDARs, reverses synapse loss when applied after Tat...

BACKGROUND: Accidental hypothermia with cardiac arrest represents a challenge for pre-hospital rescuers as well as in-hospital staff. For pre-hospital personnel, the main focus is to get the patient to the correct destination without unnecessary delay. For in-hospital personnel early information is vital to assess the possibility for resuscitation with extracorporeal re-warming. The challenge is augmented when rescuers must cross national borders to reach and/or deliver the patients. We present a case where three adolescent boys suffered severe hypothermia after a canoeing accident in Sweden...

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is employed to rescue patients with early graft dysfunction after lung transplantation (LTx). Rates of post-LTx ECMO and subsequent outcomes have been limited to single-center reports. METHODS: UNOS registry was queried for LTx recipients from March 2015 to March 2016; 2,001 recipients were identified and stratified by need for post-LTx ECMO. Logistic regression was used to determine variables associated with post-LTx ECMO...

BACKGROUND: Regarding survival and quality of life, recent mass casualty incidents have once more emphasized the importance of early identification of the correct degree of injury or illness, to enable prioritizing treatment of patients and transportation to an appropriate hospital. The present study investigated international triage algorithms in terms of sensitivity (SE) and specificity (SP) as well as the process duration in a relevant emergency patient cohort. METHODS: A total of 500 consecutive air rescue missions were evaluated by means of standardized patient records...

AIM: Removal of impacted third maxillary molar is frequently carried out without difficulties and low rate of intraoperative complications. The rare and particularly challenger to manage it is the third molar dislocation into the infratemporal fossa (IF). In this clinical report, the authors present their solution to manage and resolve this particular complication. METHODS: A 28-year-old woman was referred to the emergency rescue unit of the authors' hospital by her dentistry, after the attempt to extract the left impacted maxillary third molar...

In childhood, partial hearing loss can produce prolonged deficits in speech perception and temporal processing. Early therapeutic interventions targeting temporal processing may improve later speech-related outcomes, however. Gap detection is a measure of auditory temporal resolution that relies on auditory cortex (ACx), and early auditory deprivation alters intrinsic and synaptic properties in ACx. Thus, early deprivation should induce deficits in gap detection, which should be reflected in ACx gap sensitivity...

Gametes carry parental genetic material to the next generation. Stress-induced epigenetic changes in the germ line can be inherited and can have a profound impact on offspring development. However, the molecular mechanisms and consequences of transgenerational epigenetic inheritance are poorly understood. We found that Drosophila oocytes transmit the repressive histone mark H3K27me3 to their offspring. Maternal contribution of the histone methyltransferase Enhancer of zeste, the enzymatic component of Polycomb repressive complex 2, is required for active propagation of H3K27me3 during early embryogenesis...

BACKGROUND: Despite being an experimental therapy in preterm neonates, inhaled nitric oxide (iNO) is used as a rescue therapy when high-frequency oscillatory ventilation (HFOV) and other conventional therapies fail. OBJECTIVE: We aimed to determine the outcomes of very-low-birth-weight (VLBW) neonates with hypoxemic respiratory failure (HRF) who had received iNO after maximal conventional therapies. METHODS: We retrospectively reviewed preterm neonates (<33 weeks of gestation with a birth weight <1,500 g) who had all received HFOV and then iNO from March 1, 2009 to April 1, 2014 at the Royal Alexandra Hospital...

Clinically, systemic inflammatory response syndrome (SIRS) occurs after serious trauma or sepsis. In sepsis, neutrophils are the major effector cells responsible for eliminating pathogens. However, the role of neutrophils in development of SIRS, especially in local inflammatory area, is controversial. In this study, we established a SIRS mouse model characterized with cytokine-mediated lethal shock by intraperitoneal injection of oligodexynucleotides containing CpG motifs (CpG ODN) in D-galactosamine (D-GalN) sensitized mice based on our previous work and found that abundant neutrophils were rapidly recruited into the peritoneal cavity, where some neutrophils expressed surface TLR9 (sTLR9), defined as sTLR9(+) neutrophils...
