BACKGROUND: Aging is associated with cellular and tissue responses that collectively lead to functional and structural deterioration of tissues. Poor tissue oxygenation, or hypoxia, is involved in such responses and contributes to aging. Consequently, it could be speculated that living at higher altitude, and therefore in hypoxic conditions, accelerates aging. This assumption is indeed supported by evidence from populations residing at very high altitudes (>3,500 m). In contrast, accumulating evidence suggests that living at moderate altitudes (1,500-2,500 m) is protective rather than injurious, at least for some body systems.
SUMMARY: In this review, we critically evaluate the hypothesis that the physiological responses to mild hypoxic stress associated to life at moderate altitudes provide protection from many hypoxia-related diseases through hormesis. Hormesis means that a low dose of a stressor (here hypoxia) elicits beneficial outcomes, while a higher dose can be toxic and might explain at least in part the dose-dependent contrasting effects of hypoxia on the aging processes. The lack of well-designed longitudinal studies focusing on the role of the altitude of residence, and difficulties in accounting for potentially confounding factors such as migration, ethnicity/genetics, and socioeconomic and geoclimatic conditions, currently hampers translation of related research into uncontroversial paradigms.
KEY MESSAGES: Deeper investigations are required to understand the impact of altitude-related hypoxia on age-related diseases and to develop molecular markers of ageing/senescence in humans that are linked to hypoxia. However, the presented emerging evidence supports the view that hypoxia conditioning has the potential to improve life quality and expectancy.
The invention discloses amphiphilic modified hyaluronic acid with high biological activity. The invention takes hyaluronic acid as a main chain, takes high-activity short peptide with the functions of promoting tissue repair and regeneration as a bioactive grafting group, and takes a lipophilic group as a grafting group for promoting transdermal capacity. The hyaluronic acid material with amphipathy of hydrophile and lipophile and high bioactivity is prepared by graft modification. The hyaluronic acid derivative biological materials with different purposes are prepared by using hyaluronic acid main chains with different molecular weights, and the small molecular weight modified hyaluronic acid can be used as a functional raw material of cosmetics and can be absorbed by smearing and permeating skin. The modified polysaccharide material with large molecular weight can be used for medical and aesthetic materials or tissue regeneration or joint cavity lubrication by injection. The invention overcomes the defect of single physical filling effect of the hyaluronic acid material, and adds biological functions of polysaccharide biological material hyaluronic acid for promoting cell regeneration, collagen regeneration and the like on the inherent high moisture-preserving property of the hyaluronic acid material.

There are provided methods, systems and non-transitory storage mediums for predicting growth of an abdominal aortic aneurysm (AAA) of a patient having been diagnosed with AAA. Segmented regions of interest (ROI) comprising the aorta and adjacent structures are received by segmenting a set of images. A wall shear stress parameter and intraluminal thickness parameter is determined. A 3D parametric mesh comprising a plurality of concentric 3D mesh layers is generated, where each concentric 3D mesh layer includes a same predetermined number of nodes. The generation includes encoding the segmented ROIs, the wall shear stress parameter and the intraluminal thickness parameter as features at respective node locations in the 3D parametric mesh. A trained growth prediction machine learning model predicts, based at least on a subset of features of the 3D parametric mesh, if the given patient will show AAA growth. The training of the growth prediction model is also disclosed.
Early administration of antimicrobials remains the mainstay of treatment of severe infections. Current guidelines of management of severe sepsis suggest that initial therapy of a patient should be reviewed after 48 to 72 hours. At that stage some patients are doing well, whereas others fail to respond. When microbiology cultures of biological specimens fail to provide information for the microbial cause of an infection and susceptibilities to antimicrobials, antimicrobial stewardship relies on the use of biomarkers and mainly procalcitonin (PCT). Data so far, suggest that early changes of serum PCT can inform about the prognosis of the septic patient, with greater values reflecting a worse outcome and higher mortality and that serial measurements within 48-72 hours provide adequate information of the appropriateness of the administered antimicrobials. Moreover the use of a procalcitonin guided-treatment in surgical as well as in non-surgical critically-ill patients, is seen to be non-inferior to the standard antibiotic approach and leads to a shorter antibiotic exposure, having possible beneficial effect on reducing microbial resistance and therapy costs.

In the largest study conducted so far, de Jong et al showed that PCT-guided stop of treatment was not only safe compared with standard of care antibiotic duration, but also led to a better outcome i.e. significant decrease of both 28-day and 1-year mortality. The results of this study are a major contribution in the field of critical care since they prove for the first time that PCT guidance of antimicrobial treatment allows not only proper antimicrobial stewardship but it is also associated with survival benefit. However, de Jong et al did not provide findings to explain the underlying mechanism of survival benefit. As a rule critically ill patients run two major risks coming from the long-term administration of antimicrobials; the first is infections by Clostridium difficile coming from the ecological damage of gut flora and the second is the risk of infections by multidrug-resistant (MDR) bacteria colonizing the gut. MDR is emerging after the ecological pressure of broad-spectrum antimicrobial usually administered to the critically ill patient.
BACKGROUND AND PURPOSE: Chronic postsurgical pain after total knee arthroplasty (TKA) is frequent and may be reduced by pain neuroscience education (PNE), teaching people about pain from a neurobiological perspective. This study investigated primarily the effectiveness of 2 individual sessions of PNE versus usual care on pain levels 3 months postoperatively in patients undergoing TKA. Secondary outcomes were physical functioning, stiffness, health-related quality of life, pain catastrophizing, attention to pain, and levels of anxiety and depression.
METHODS: A prospective single-center, parallel-group randomized controlled trial was undertaken including patients aged 18 years or older scheduled for primary TKA. 68 patients were randomly assigned to PNE or usual care. The primary outcome was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score 3 months postoperatively. Outcomes were measured preoperatively, at 2 weeks (acute phase), and at 3 and 12 months postoperatively.
RESULTS: We found no statistically significant difference (0.4 points; 95% confidence interval [CI] -1.7 to 2.4) in WOMAC pain scores 3 months after TKA between the PNE and control group. We found a statistically significant difference between the 2 groups for attention to pain at 3 months in favor of PNE (P = 0.02).
CONCLUSION: This RCT showed that PNE was not superior to usual care in terms of reducing pain at 3 months after TKA. Attention to pain, as a secondary outcome, was significantly lower in the PNE group compared with usual care. Other secondary outcome measures showed no significant differences.

Despite screening programmes, numerous clinical studies and new breast imaging techniques, breast cancer incidence for women continues to rise. The arrival of predictive and personalized medicine could clearly redefine our screening recommendations. One promising approach to improving screening would be to use tools to predict the risk of developing breast cancer, including polygenic risk scores (PRS). This approach will enable us to offer women risk-based screening by adapting the frequency, type and age of screening. This article reviews some definitions of the PRS and breast cancer screening. We also explain the risk assessment models that have been developed and the various studies underway on personalized screening.
The patient will undergo quality of life assessment and skin imaging (ultrasonography and reflectance confocal microscopy). Brachytherapy will be performed over six outpatient visits over 2-3 weeks, on non-consecutive days. Patients will then be followed for 5 years. Reflectance confocal microscopy is optional for the participating sites.
Adjacent segment degeneration (ASD) is a major postoperative complication associated with posterior lumbar interbody fusion (PLIF). Early-onset ASD may differ pathologically from late-onset ASD. The aim of this study was to identify risk factors for early-onset ASD at the cranial segment occurring within 2 years after surgery. A retrospective study was performed for 170 patients with L4 degenerative spondylolisthesis who underwent one-segment PLIF. Of these patients, 20.6% had early-onset ASD at L3-4. In multivariate logistic regression analysis, preoperative larger % slip, vertebral bone marrow edema at the cranial segment on preoperative MRI (odds ratio 16.8), and surgical disc space distraction (cut-off 4.0 mm) were significant independent risk factors for early-onset ASD. Patients with preoperative imaging findings of bone marrow edema at the cranial segment had a 57.1% rate of early-onset ASD. A vacuum phenomenon and/or concomitant decompression at the cranial segment, the degree of surgical reduction of slippage, and lumbosacral spinal alignment were not risk factors for early-onset ASD. The need for fusion surgery requires careful consideration if vertebral bone marrow edema at the cranial segment adjacent to the fusion segment is detected on preoperative MRI, due to the negative impact of this edema on the incidence of early-onset ASD.
Few studies have reported the application of vacuum-sealing drainage of infected dialysis vascular access wounds. Herein, we present a case of buttonhole-related arteriovenous fistula infection treated with vacuum-sealing drainage. A 53-year-old female hemodialysis patient was hospitalized with an inflamed arteriovenous fistula. The patient underwent non-tunneled catheterization for dialysis and was treated with moxifloxacin and vancomycin for staphylococcal infection. On Day 3, the skin overlying the inflamed fistula was ulcerated, resulting in severe hemorrhage. Emergency surgery was performed along with vacuum-sealing drainage for fistula reconstruction. Vacuum-sealing drainage accelerated the recovery of the wound without complications. No further access complications occurred during over a 3-year follow-up.
Top-down projections transmit a series of signals encoding pain sensation to the ventrolateral periaqueductal gray (vlPAG), where they converge with various incoming projections to regulate pain. Clarifying the upstream regulatory hierarchy of vlPAG can enhance our understanding of the neural circuitry involved in pain modulation. Here, we show that a in a mouse model of spared nerve injury (SNI), activation of a circuit arising from posterior paraventricular thalamic nucleus CaMKIIα-positive neurons (PVPCaMKIIα) projects to gamma-aminobutyric acid neurons in the rostral zona incerta (ZIrGABA) to facilitate the development of pain hypersensitivity behaviors. In turn, these ZIrGABA neurons project to CaMKIIα-positive neurons in the vlPAG (vlPAGCaMKIIα), a well-known neuronal population involved in pain descending modulation. In vivo calcium signal recording and whole-cell electrophysiological recordings reveal that the PVPCaMKIIα→ZIrGABA→vlPAGCaMKIIα circuit is activated in SNI models of persistent pain. Inhibition of this circuit using chemogenetics or optogenetics can alleviate the mechanical pain behaviors. Our study indicates that the PVPCaMKIIα→ZIrGABA→vlPAGCaMKIIα circuit is involved in the facilitation of neuropathic pain. This previously unrecognized circuit could be explored as a potential target for neuropathic pain treatment.
Systems and methods for preparing medical biomaterials from amniotic tissue or the like are discussed. In some embodiments, the amniotic membrane tissue is ground and used to create a hydrogel. Variations in materials and methods of preparation result in certain product characteristics, such as shelf life and/or thickening time for protein activity, suitable for various therapeutic uses. As an illustrative example, a hydrogel of finely ground amniotic membrane tissue may be freeze-dried and freeze-ground to a particle size suitable for use in ophthalmic, oral, or other treatments. In some embodiments, the present invention includes an efficient and effective cryogenic grinding process and mechanical engineering design to produce fine, uniformly sized, and highly dissolved powder particles for industrial mass production. This is accomplished while maintaining the original important physical, chemical and biological properties of the biological material being milled. Exemplary include grinding amniotic membrane tissue, protein, collagen, mucopolysaccharide, and lyophilized tissue to produce a medical biomaterial.
This is a prospective multicenter study. Patients with T1-2 Breast cancer and clinically negative axilla on palpation, 1-2 suspicious nodes on ultrasound, and a biopsy proven positive node (by core biopsy of fine needle aspiration) will have a radioactive seed (I125) placed in their clipped node before surgery. At the time of surgery, patients that are scheduled for breast conserving surgery or mastectomy will have sentinel node biopsy (SNB) using radioactive dye (Tc99) +/- blue dye as well as retrieval of the clipped node using radioactive seed localisation (RSL). Removal of the I125 radioactive seed in the clipped node will be performed before the Tc99 counts are performed to prevent "shine through" and biased measurements. Imaging of the surgical specimen will confirm retrieval of the clipped node. Prospectively recorded information on pre-operative axillary imaging, characteristics of the retrieved nodes in the operating room and detailed pathological analysis of each corresponding node will be performed. Completion node dissection (CND) is not mandatory in this study but recommended if the clipped positive node is not retrieved, if 4 nodes or more are positive or if 3 nodes are positive in the absence of axillary radiation. The benefits of adding RSL to SNB and the benefits of adding SNB to RSL staging of the axilla will be evaluated in this study and will help to better define the value of using TAD in this patient population.

The recommended treatment for early stage thymoma without myasthenia gravis is complete thymectomy (CT). Limited thymectomy (LT) (simply resecting the thymoma with safe surgical margins) is gaining popularity. In this study, we compared the surgical and oncological results of complete and limited thymectomy in non-myasthenic patients with early stage thymoma. Non-myasthenic, Masaoka stage I-II, 86 patients who underwent surgical resection for thymoma were included in the study. Complete thymectomy (n:44) included patients who had resection of the thymoma together with the entire thymus and limited thymectomy (n:42) included patients who had resection of the thymoma without remaining thymus. The surgical approach, tumor size, histological type, pathological stage, adjuvant therapy, complications, postop myasthenia gravis, recurrence and death were recorded and compared between groups. Complete thymectomy group had more WHO type B1-3 tumors, more complications and more deaths than patients in the limited thymectomy group (p = 0.03, 0.018 and 0.023 respectively). Although statistically not significant CT group had more recurrences than LT group (11.4%/4.8%, p = 0.43). The 10-year freedom from recurrence (FFR) rate in the CT group was 84.8% and in the LT group ıt was 97.6%, the difference was not statistically significant (p = 0.15). None of the factors including surgical extent analysed with univariate and multivariate analysis had a significant effect on FFR. Limited thymectomy may be a good treatment option for non-myasthenic early stage thymoma patients but randomized controlled trials with long follow-up periods, ideally comparing patients operated with minimally invasive surgery are necessary.
Randomized participants in this group will be recommended to follow a Mediterranean Diet, based on the use of olive oil as the main source of visible fat and regular consumption of vegetables (≥2 servings/day), fruits (≥3 servings/day), legumes (≥3 servings/week) and fish (≥3 times a week), reducing the consumption of red meat or sausages (\<2 times a week) and eliminating the consumption of sugary drinks, pastries or industrial pastries. In this Mediterranean Diet, an energy restriction of 30% of the estimated energy needs (Harris-Benedict equation) will be established.
Patients will receive high intensity interval training. The program will be in form of Frequency: High intensity interval training will be scheduled 3 times per week for 12 week Intensity 90% of target heart rate including 10 bouts of 1 minute interspersed with 10 bouts of 1 minute of active recovery 50% of target heart rate. Duration the session will last 30 minutes includes warming up and cooling down periods.
All infants fulfilling the inclusion criteria during the study period are asked to participate in this randomized controlled trial of LISA premedication. Written informed parental consent is acquired from all of the participants. After the consent, individuals needing the LISA will receive premedication as follows: caffeine (in case of gestational age \<32 weeks and not already given), glycopyrrolate, and randomly either ketamine or fentanyl. The investigators and medical staff are blinded to the fact which study medication is given. This study is a pilot study and 20 patients are recruited for both groups. Randomization is done in the blocks of four.

S-ketamine (Ketanest-S 5 mg/ml) or fentanyl (Fentanyl-Hamel diluted to 5 μg/ml) is used as a masked study drug. Both study drug solutions appear equally transparent. Drug administration is started with glucopyrrolate (Robinul 0.2 mg/ml), which is given intravenously at a dose of 5 µg/kg. Thereafter, the masked study drug is administered intravenously slowly in one to two minute injection of 0.2 ml/kg. In this way, doses of S-ketamine 1 mg/kg or alternatively fentanyl 1 μg/kg is received. After five minutes (from the beginning of administration of the study drug), videolaryngoscopy is started. If the study drug does not have sufficient effect, the study drug may be repeated with the same dose. If study drug fails to give appropriate conditions to LISA procedure, midazolam 0,1 mg/kg can be used as an additional drug.
