Premature ovarian failure (POF) is a refractory disease for clinical treatment with the goal of restoring fertility. In this study, umbilical cord mesenchymal stem cells on a collagen scaffold (collagen/UC-MSCs) can activate primordial follicles in vitro via phosphorylation of FOXO3a and FOXO1. Transplantation of collagen/UC-MSCs to the ovaries of POF patients rescued overall ovarian function, evidenced by elevated estradiol concentrations, improved follicular development, and increased number of antral follicles...

OBJECTIVE: To compare the long-term outcomes of patients who had been randomly allocated to receive primary titanium cranioplasty or autologous bone graft following decompressive craniectomy. METHODS: Sixty-four patients had been previously enrolled and randomised to receive either their own bone graft or a primary titanium cranioplasty. Functional and cosmetic outcomes had previously been assessed at 1-year following the cranioplasty procedure. Hospital records and the Picture Archiving communication system were reviewed to determine how many patients had cranioplasty failure or associated complications such as seizures beyond 1 year-with a minimum of 24-month follow-up...

BACKGROUND: Providing effective positive pressure ventilation is considered to be the single most important component of successful neonatal resuscitation. Ventilation is frequently initiated manually with bag and face mask (BMV) followed by endotracheal intubation if respiratory depression continues. These techniques may be difficult to perform successfully resulting in prolonged resuscitation or neonatal asphyxia. The laryngeal mask airway (LMA) may achieve initial ventilation and successful resuscitation faster than a bag-mask device or endotracheal intubation...

BACKGROUND: Trauma is a global burden of disease and one of the main causes of death worldwide. Therefore, many countries around the world have implemented a wide range of different initiatives to minimize mortality rates after trauma. One of these initiatives is the bundling of treatment expertise in trauma centers and the establishment of trauma networks. Germany has a decentralized system of trauma care medical centers. Severely injured patients ought to receive adequate treatment in both level I and level II centers...

Hybrid sterility is one of the reproductive isolation mechanisms leading to speciation. Prdm9 , the only known vertebrate hybrid sterility gene, causes failure of meiotic chromosome synapsis and infertility in male hybrids between two mouse subspecies. But within species Prdm9 determines the sites of programmed DNA double-strand breaks and meiotic recombination hotspots. To investigate the relation between Prdm9 -controlled meiotic arrest and asynapsis, we inserted random stretches of consubspecific homology on several autosomal pairs in sterile hybrids and analyzed their ability to form synaptonemal complexes and rescue male fertility...

Tetanus is an acute specific infection caused by obligate anaerobes, which is still a serious public health problem. Tetanus bacterium is an obligate anaerobic bacterium, widely distributed in nature, which can exist in dust, soil, human or animal excrement. The bacteria invade the body primarily through the skin or mucosal wounds, and most commonly in trauma and burn patients, unclean newborns, and unsafe surgical instruments. Exotoxin produced by tetanus bacteria can cause temporary changes in the central nervous system, manifested as systemic skeletal muscle persistence and paroxysmal spasm, severe cases of laryngospasm, asphyxia, lung infections and organ failure, which is a very serious and potentially fatal disease...

Aggregates of human islet amyloid polypeptide (IAPP) in the pancreas of patients with type 2 diabetes (T2D) are thought to contribute to β cell dysfunction and death. To understand how IAPP harms cells and how this might be overcome, we created a yeast model of IAPP toxicity. Ste24, an evolutionarily conserved protease that was recently reported to degrade peptides stuck within the translocon between the cytoplasm and the endoplasmic reticulum, was the strongest suppressor of IAPP toxicity. By testing variants of the human homolog, ZMPSTE24, with varying activity levels, the rescue of IAPP toxicity proved to be directly proportional to the declogging efficiency...

Administration of vaccines combined with the good management and strict biosecurity is an effective way for Newcastle disease (ND) control. However, vaccine failure is continuously reported in some countries mainly because the antigenic difference between the used vaccine and field strains even they are of one serotype. Therefore, development of antigen-matched ND vaccines is needed to improve the vaccine efficacy in birds. In this study, we introduced four site mutations, K1756A, D1881A, K1917A and E1954Q, respectively, into the large protein gene of the virulent genotype VII Newcastle disease virus (NDV) G7 strain using reverse genetics technology...

BACKGROUND: Emergency rescue lung resection is rarely performed to treat congenital lung cysts (CLCs) in neonates. Many reports have described fetal CLC treatment; however, prenatal predictors for postnatal respiratory failure have not been characterized. We hypothesized that fetal imaging findings are useful predictors of emergency surgery. METHODS: We retrospectively studied patients with CLC who underwent lung surgery during the neonatal period in our hospital between January 2001 and December 2015...

Infection with seasonal influenza A virus (IAV) leads to lung inflammation and respiratory failure, a main cause of death in influenza infected patients. Previous experiments in our laboratory indicated that Bruton's tyrosine kinase (Btk) plays a substantial role in regulating inflammation in the respiratory region during acute lung injury (ALI) in mice, therefore we sought to determine if blocking Btk activity had a protective effect in the lung during influenza induced inflammation. A Btk inhibitor (Btk Inh...

Antibiotic resistance is a growing crisis and a grave threat to human health. It is projected that antibiotic-resistant infections will lead to 10 million annual deaths worldwide by the year 2050. Among the most significant threats are carbapenem-resistant Enterobacteriaceae (CRE), including carbapenem-resistant Klebsiella pneumoniae (CRKP), which lead to mortality rates as high as 40 to 50%. Few treatment options are available to treat CRKP, and the polymyxin antibiotic colistin is often the "last-line" therapy...

Extracorporeal membrane oxygenation (ECMO) is one of the most frequent forms of extracorporeal life support (ECLS) and can be used as rescue therapy in patients with severe respiratory failure resulting from burns and/or smoke inhalation injury. Experience and literature on this treatment option is still very limited, consequently results are varied. We report a retrospective analysis of our experience with veno-venous (VV) ECMO in burn patients. All five patients, three male and two female (age: 28-37 years) had flame type burns and smoke inhalation injury...

BACKGROUND: Lactational competence requires plasminogen, the zymogen of the serine protease, plasmin. Plg-RKT is a unique transmembrane plasminogen receptor that promotes plasminogen activation to plasmin on cell surfaces. Plg-RKT -/- mice are viable, but no offspring of Plg-RKT -/- female mice survive to weaning. OBJECTIVES: We investigated potential lactational failure in Plg-RKT -/- mice and addressed causal mechanisms. METHODS: Fibrin accumulation, macrophage infiltration, processing of extracellular matrix components, effects of genetic deletion of fibrinogen, expression of fibrosis genes, and proliferation and apoptosis of epithelial cells were examined in lactating mammary glands of Plg-RKT -/- and Plg-RKT +/+ mice...

AIMS: Mechanical ultrafiltration (UF) involves the removal of an iso-osmotic filtrate from the blood. Its benefit in acute decompensated heart failure, however, remains inconclusive. We sought to better understand the direct effects of UF in comparison to an aggressive, urine output-guided pharmacological protocol for decongestion on fluid loss, renal function, and neurohormonal activation. METHODS AND RESULTS: A per-protocol analysis of the Cardiorenal Rescue Study in Acute Decompensated Heart Failure (CARRESS-HF) trial (n = 188) was performed...

PURPOSE OF REVIEW: To review the current medical and stem-cell therapy for spinal muscular atrophy (SMA) and prenatal transplantation of amniotic fluid stem cells in the future. RECENT FINDINGS: SMA is an autosomal recessive inheritance of neurodegenerative disease, which is caused of the mutation in survival motor neuron. The severe-type SMA patients usually die from the respiratory failure within 2 years after birth. Recently, researchers had found that 3-methyladenine could inhibit the autophagy and had the capacity to reduce death of the neurons...

Failure to rescue is death occurring after a complication. Rapid response teams developed as a prompt intervention for patients with early clinical deterioration, generally from medical conditions or complications. Patients with surgical complications or surgical pathology require prompt evaluation and management by surgeons to avoid deterioration; this is surgical rescue. Patients in the medical intensive care unit may develop intra-abdominal pathology that requires expeditious operative intervention. Acute care surgeons should serve as the surgical rapid response team to help assess and manage these complex patients...

BACKGROUND: An association between frailty and mortality exists; we hypothesized this is secondary to failure to rescue (F2R). STUDY DESIGN: Data were obtained from the National Surgical Quality Improvement Program (2005-2012) for patients undergoing thoracoabdominal surgery. Using the modified frailty index (MFI), patients were classified as not (0 points), mildly (1 point), moderately (2 points), and severely (=/>3) frail. RESULTS: 962,913 patients were included; a majority were non-frail (52...

Severe anemia and iron deficiency are common complications in chronic kidney disease. The cause of renal anemia is multifactorial and includes decreased erythropoietin (Epo) production, iron deficiency, and inflammation, and it is currently treated with injections of synthetic Epo. However, the use of recombinant Epo has several adverse effects. We previously reported that high fibroblast growth factor 23 (FGF23) levels in mice are associated with decreased red blood cell production, whereas genetic inactivation of Fgf23 results in expansion of the erythroid lineage...

Background and Objectives: Morbidity and mortality have been shown to increase several-fold in patients who have undergone bariatric surgery and returned to the operating room after their initial procedures. Failure-to-rescue (FTR) analyses allow for an understanding of patient management and outcomes that is more distinguished than assessments of adverse occurrences and mortality rates alone. The objective of this study was to assess failure to rescue (FTR) and the characteristics and outcomes of patients undergoing reoperation after laparoscopic gastric bypass (LGBP) and laparoscopic sleeve gastrectomy (LSG)...
