[Comparative study of differentiation potential of mesenchymal stem cells derived from orofacial system into vascular endothelial cells].

OBJECTIVE To compare the proliferation and capacity of differentiation to vascular endothelial cells and angiogenesis induction among stem cells from human exfoliated deciduous teeth (SHED), dental pulp stem cells (DPSC) and human bone marrow mesenchymal stem cells (BMSC) from orofacial bone. METHODS SHED and DPSC were isolated from pulp tissue of the patients. BMSC were isolated from orthognathic or alveolar surgical sites. The surface markers of the cells were detected by flowcytometry. Cell counting kit-8 (CCK-8) assays were conducted to detect the proliferation ability of the cells. The cells were induced into endothelial cells with conditional medium and then the induced cells were cultured in Matrigel medium. The expression of angiogenesis-related genes such as platelet endothelial cell adhesion molecule-1 (PECAM-1/CD31), vascular endothelial growth factor (VEGF), vascular endothelial growth factor receptor 1 (VEGFR1), vascular endothelial growth factor receptor 2 (VEGFR2) and von Willebrand Factor (vWF) were quantified by real-time PCR. The cells were cultured in chick embryo chorioallantoic membrane (CAM) and the vessels were counted after 5 days. RESULTS The cell surface markers CD73, CD90, CD105 and CD146 of all the stem cells were positive, CD34 and CD45 were negative. The CD146 positive rate of SHED and DPSC was higher than that of BMSC. SHED had a higher proliferation rate than DPSC and BMSC. After angiogenic induction for 14 d, 3 kinds of cells emanated pseudopodia formed grid structure long vasculature in Matrigel media. The total length of tube formation of induced BMSC (7 759.7 μm) and SHED (7 734.3 μm) was higher than DPSC (5 541.0 μm). The meshes number of induced SHED (70.7) was higher than DPSC (60) and BMSC (53.7) in Matrigel medium. The expression of CD31, VEGFR2 and vWF genes of SHED were higher than those of BMSC and DPSC. VEGFR1 gene expression of BMSC was higher than that of the other groups, and SHED was higher than DPSC. The expression of VEGF showed no difference among the cells. No deference was showed between the effect of the stem cells and negative control on new formed vessels in CAM. The total length of vessels of SHED (30.4 mm) was higher than that of the negative control (20.9 mm) and BMSC (28.0 mm). CONCLUSION SHED, DPSC and BMSC can differentiate into vascular endothelial cells. SHED showed a stronger angiogenesis differentiation and proliferation potential compared with DPSC and BMSC.
The Wnt/Ca2+ pathway is involved in interneuronal communication mediated by tunneling nanotubes

Tunneling nanotubes (TNTs) are actin‐based transient tubular connections that allow direct communication between distant cells. TNTs play an important role in several physiological (development, immunity, and tissue regeneration) and pathological (cancer, neurodegeneration, and pathogens transmission) processes. Here, we report that the Wnt/Ca2+ pathway, an intracellular cascade that is involved in actin cytoskeleton remodeling, has a role in TNT formation and TNT‐mediated transfer of cargoes. Specifically, we found that Ca2+/calmodulin‐dependent protein kinase II (CaMKII), a transducer of the Wnt/Ca2+ pathway, regulates TNTs in a neuronal cell line and in primary neurons. We identified the β isoform of CaMKII as a key molecule in modulating TNT formation and transfer, showing that this depends on the actin‐binding activity of the protein. Finally, we found that the transfer of vesicles and aggregated α‐synuclein between primary neurons can be regulated by the activation of the Wnt/Ca2+ pathway. Our findings suggest that Wnt/Ca2+ pathway could be a novel promising target for therapies designed to impair TNT‐mediated propagation of pathogens.
Identification of predictors for acute postoperative pain after gynecological laparoscopy (STROBE-compliant article)

Abstract While the pain after gynecological laparoscopy is assumed to be minor, many women suffer from unexpected postoperative pain in the post-anesthesia care unit (PACU). Prior identification of these patients is significant for effective analgesia. Therefore, we sought to determine the predictors for acute postoperative pain after gynecological laparoscopy. The data of 280 patients undergoing gynecological laparoscopy were analyzed. Data included demographic characteristics, previous obstetric/gynecologic surgical history, menstruation pattern including dysmenorrhea severity, gynecological hormone administration history, and surgical data (surgical time, endometriosis severity, adhesion, drainage insertion, and surgery type). Univariate analysis and binary logistic regression were used to evaluate predictors for substantial pain in the PACU after gynecologic laparoscopy. Among the 280 patients, 115 (41%) suffered from substantial postoperative pain in the PACU. Whenever the level of dysmenorrhea became more severe (none → mild → moderate → severe), the risk of substantial pain in the PACU increased 2.9-fold (odds ratio [OR] 2.92, 95% confidence interval [CI] 2.11–4.03, P < .001). Moreover, patients undergoing laparoscopy for ectopic pregnancy had a higher risk of substantial pain compared with the others (OR 3.11, 95% CI 1.36–7.12, P = .007). Other factors did not show a significant association with substantial pain. Patients with preoperative severe dysmenorrhea and those undergoing laparoscopy for ectopic pregnancy should be considered to have a high risk of substantial postoperative pain in the PACU so that they receive prompt and aggressive analgesic intervention. In particular, dysmenorrhea severity is clinically valuable as a useful predictor for substantial pain after gynecological laparoscopy.
Comparison of International Consensus Conference guidelines and WIND classification for weaning from mechanical ventilation in Brazilian critically ill patients

Abstract The knowledge of weaning ventilation period is fundamental to understand the causes and consequences of prolonged weaning. In 2007, an International Consensus Conference (ICC) defined a classification of weaning used worldwide. However, a new definition and classification of weaning (WIND) were suggested in 2017. The objective of this study was to compare the incidence and clinical relevance of weaning according to ICC and WIND classification in an intensive care unit (ICU) and establish which of the classifications fit better for severely ill patients. This study was a retrospective cohort study in an ICU in a tertiary University Hospital. Patient data, such as population characteristics, mechanical ventilation (MV) duration, weaning classification, mortality, SAPS 3, and death probability, were obtained from a medical records database of all patients, who were admitted to ICU between January 2016 and July 2017. Three hundred twenty-seven mechanically ventilated patients were analyzed. Using the ICC classification, 82% of the patients could not be classified, while 10%, 5%, and 3% were allocated in simple, difficult, and prolonged weaning, respectively. When WIND was used, 11%, 6%, 26%, and 57% of the patients were classified into short, difficult, prolonged, and no weaning groups, respectively. Patients without classification were sicker than those that could be classified by ICC. Using WIND, an increase in death probability, MV days, and tracheostomy rate was observed according to weaning difficult. Our results were able to find the clinical relevance of WIND classification, mainly in prolonged, no weaning, and severely ill patients. All mechanically ill patients were classified, even those sicker with tracheostomy and those that could not finish weaning, thereby enabling comparisons among different ICUs. Finally, it seems that the new classification fits better in the ICU routine, especially for more severe and prolonged weaning patients.
Preoperative cardiac and respiratory investigations do not predict cardio‐respiratory complications after pancreatectomy

The process of undergoing a pancreatic resection places a patient under notable physiologic strain throughout the perioperative journey, with well recognized risks of postoperative cardiopulmonary complications. Preoperative preparations and screening often incorporate a barrage of testing, including electrocardiograms, transthoracic echocardiography, chest X‐rays and spirometric evaluations. However, the current literature does not demonstrate whether these common tests provide any predictive correlation with postoperative cardiopulmonary complications. This retrospective study is structured to identify complications in post‐pancreatic resection patients and assess for a predictive correlation with preoperative test results.
Psychological Distress and Sleep Disturbance Among Female Nurses: Anxiety or Depression?

Introduction: Sleep quality is an important issue in nurses’ mental and general health. Long-term psychological distress leads to increased sleep disturbances among nurses. However, which forms of psychological distress are most associated with sleep disturbances is unclear among female nurses. Methodology: To determine which psychological distress factors are associated with sleep disturbances among female nurses. A total of 119 female Taiwanese nurses were recruited and surveyed using the Occupational Stress Indicator–2, Beck Anxiety Inventory, Beck Depression Inventory–II, and Pittsburgh Sleep Quality Index. Results: Overall, 68.9% of the nurses were poor sleepers, and 20.2% and 11.7% of them had more than moderate levels of anxiety and depression, respectively. A logistic regression analysis showed that sleep disturbances were associated with higher levels of depression and poorer general health. Discussion: Compared with anxiety, depression more heavily influences sleep disturbances among female nurses. Depression prevention should thus be a focus of mental health promotion for female nurses.
Human neural stem cell transplant location–dependent neuroprotection and motor deficit amelioration in rats with penetrating traumatic brain injury

BACKGROUND Penetrating traumatic brain injury induces chronic inflammation that drives persistent tissue loss long after injury. Absence of endogenous reparative neurogenesis and effective neuroprotective therapies render injury-induced disability an unmet need. Cell replacement via neural stem cell transplantation could potentially rebuild the tissue and alleviate penetrating traumatic brain injury disability. The optimal transplant location remains to be determined. METHODS To test if subacute human neural stem cell (hNSC) transplant location influences engraftment, lesion expansion, and motor deficits, rats (n = 10/group) were randomized to the following four groups (uninjured and three injured): group 1 (Gr1), uninjured with cell transplants (sham+hNSCs), 1-week postunilateral penetrating traumatic brain injury, after establishing motor deficit; group 2 (Gr2), treated with vehicle (media, no cells); group 3 (Gr3), hNSCs transplanted into lesion core (intra); and group 4 (Gr4), hNSCs transplanted into tissue surrounding the lesion (peri). All animals were immunosuppressed for 12 weeks and euthanized following motor assessment. RESULTS In Gr2, penetrating traumatic brain injury effect manifests as porencephalic cyst, 22.53 ± 2.87 (% of intact hemisphere), with p value of <0.0001 compared with uninjured Gr1. Group 3 lesion volume at 17.44 ± 2.11 did not differ significantly from Gr2 (p = 0.36), while Gr4 value, 9.17 ± 1.53, differed significantly (p = 0.0001). Engraftment and neuronal differentiation were significantly lower in the uninjured Gr1 (p < 0.05), compared with injured groups. However, there were no differences between Gr3 and Gr4. Significant increase in cortical tissue sparing (p = 0.03), including motor cortex (p = 0.005) was observed in Gr4 but not Gr3. Presence of transplant within lesion or in penumbra attenuated motor deficit development (p < 0.05) compared with Gr2. CONCLUSION In aggregate, injury milieu supports transplanted cell proliferation and differentiation independent of location. Unexpectedly, cortical sparing is transplant location dependent. Thus, apart from cell replacement and transplant mediated deficit amelioration, transplant location–dependent neuroprotection may be key to delaying onset or preventing development of injury-induced disability.

Two distinct variants of mycosis fungoides (MF): Folliculotropic MF and erythrodermic MF

Mycosis fungoides (MF) is the most frequent type of cutaneous T‐cell lymphoma. Folliculotropic MF (fMF) and erythrodermic MF (eMF) are two distinct variants of MF. Both variants have been considered aggressive and most cases are less responsive to standard skin‐directed therapies than classical MF. We, however, experienced many cases with fMF or eMF who showed indolent clinical courses. In this article, we reviewed 10 cases with fMF and 13 cases with eMF who came to our department between 2005 and 2017. In patients with fMF, monotherapy with topical corticosteroid was effective in two cases (20%) and ultraviolet phototherapy with oral retinoid controlled disease activity in two cases (20%). Five patients with eMF (38%) responded well to ultraviolet phototherapy. In conclusion, patients with early fMF and a subgroup of eMF patients have an indolent disease course, as was proposed among the specialists. Skin‐directed therapies are preferable rather than aggressive treatment in those cases.
Microbial induced solidification and stabilization of municipal solid waste incineration fly ash with high alkalinity and heavy metal toxicity

This paper presents an experimental study on the applicability of microbial induced carbonate precipitation (MICP) to treat municipal solid waste incineration (MSWI) fly ash with high alkalinity and heavy metal toxicity. The experiments were carried out on fly ashes A and B produced from incineration processes of mechanical grate furnace and circulating fluidized bed, respectively. The results showed that both types of fly ashes contained high CaO content, which could supply sufficient endogenous Ca for MICP treatment. Moreover, S. pasteurii can survive from high alkalinity and heavy metal toxicity of fly ash solution. Further, the unconfined compressive strength (UCS) of MICP treated fly ashes A and B reached 0.385MPa and 0.709 MPa, respectively. The MICP treatment also resulted in a reduction in the leaching toxicity of heavy metals, especially for Cu, Pb and Hg. MICP had a higher solidification and stabilization effect on fly ash B, which has finer particle size and higher Ca content. These findings shone a light on the possibility of using MICP technique as a suitable and efficient tool to treat the MSWI fly ash.
Pathological personality facets and emotion (dys)regulation in gambling disorder.

A number of researches showed high prevalence of personality disorders among addicted gamblers. However, there are still few studies investigating the role of pathological personality facets in Gambling Disorder (GD). Moreover, the nature of the relationship between GD and pathological personality is not clear. We administered to a group of addicted gamblers (N = 79) and a group of healthy participants (N = 101) a battery of self-report questionnaires encompassing the South Oaks Gambling Screen (SOGS), The Personality Inventory for DSM-V (PID-5), the Difficulties in Emotion Regulation Scale (DERS) and the Emotion Regulation Questionnaire (ERQ). Analyses of variance showed that addicted gamblers, compared to healthy participants, scored higher on most of the subscales of the DERS, on the Suppression Dimension of the ERQ and on the five main domains of the PID-5 whereas they obtained lower scores on the Reappraisal subscale of the ERQ. Moreover, multiple regression analyses indicated that some specific facets of pathological personality, emotion dysregulation and lack of cognitive reappraisal, significantly predict GD's severity. Finally, emotion dysregulation levels and lack of cognitive reappraisal partially mediated the relationship between these and GD's severity. Our results confirmed the central roles played by both pathological personality and deficit in emotion regulation capacities in GD. Specifically, Impulsivity, Lack of Perseverance and Suspiciousness may be important predictors of GD severity. Moreover, emotion dysregulation and lack of adaptive emotion regulation strategies partially explained such relationship. As such, training for emotion regulation abilities appears strategically useful in the treatment of addicted gamblers with pathological personality traits.
The Prevalence of Delirium in An Older Acute Surgical Population and Its Effect on Outcome

Background: With an ageing population, an increasing number of older adults are admitted for assessment to acute surgical units. Older adults have specific factors that may influence outcomes, one of which is delirium (acute cognitive impairment). Objectives: To establish the prevalence of delirium on admission in an older acute surgical population and its effect on mortality. Secondary outcomes investigated include hospital readmission and length of hospital stay. Method: This observational multi-centre study investigated consecutive patients, ≥65 years, admitted to the acute surgical units of five UK hospitals during an eight-week period. On admission the Confusion Assessment Method (CAM) score was performed to detect delirium. The effect of delirium on important clinical outcomes was investigated using tests of association and logistic regression models. Results: The cohort consisted of 411 patients with a mean age of 77.3 years (SD 8.1). The prevalence of admission delirium was 8.8% (95% CI 6.2–11.9%) and cognitive impairment was 70.3% (95% CI 65.6–74.7%). The delirious group were not more likely to die at 30 or 90 days (OR 1.1, 95% CI 0.2 to 5.1, p = 0.67; OR 1.4, 95% CI 0.4 to 4.1. p = 0.82) or to be readmitted within 30 days of discharge (OR 0.9, 95% CI 0.4 to 2.2, p = 0.89). Length of hospital stay was significantly longer in the delirious group (median 8 vs. 5 days respectively, p = 0.009). Conclusion: Admission delirium occurs in just under 10% of older people admitted to acute surgical units, resulting in significantly longer hospital stays.
Preliminary Study of a Single Instillation of Low-Concentration High-Volume Silver Nitrate Solution for Chyluria: Is >10 mL Instillation an Absolute Contraindication in the Real World?

Silver nitrate instillation (SNI) is one form of treatment for chyluria. However, there is the opinion that a high volume of SNI (>10 mL) should be avoided because life-threatening complications have been reported. However, we have noticed that most severe complications occur in high-concentration treatments (≥1%), even with a small volume. In addition, a small volume (≤10 mL) of low-concentration (<1%) SNI occasionally causes recurrence. Based on these facts, we aimed to evaluate a preliminary study of a novel single-injection regimen of low-concentration high-volume SNI. In this preliminary study, nine patients who underwent SNI were retrospectively examined. Patient characteristics, anesthesia, procedure, efficacy, complications, and duration of hospital stay were investigated. The volume of silver nitrate solution was decided based on symptoms, findings of pyelography, and vital signs, and it was given as a single instillation. This study was approved by the Institutional Review Board. The ranges of silver nitrate concentration and volume were 0.1%–0.5% and 15–30 mL, respectively. In all patients, proteinuria and cloudy urine disappeared immediately. However, two patients had recurrence after the initial SNI. These two patients were subsequently treated with increasing concentrations of silver nitrate (0.2% and 0.5%) from 0.1%, and they had complete symptomatic relief without recurrence for more than 6 years. None of the patients experienced severe complications. In conclusion, our preliminary study showed that a single instillation of low-concentration (0.1%–0.5%) and high-volume (15–30 mL) SNI is safe and useful. It is worth considering as a treatment option for chyluria.
The sphenoidal emissary foramen and the emissary vein: Anatomy and clinical relevance

Although the sphenoidal emissary foramen (SEF) and its content are anatomically and clinically relevant, accurate description of them in the modern literature is lacking. This study aimed to examine and describe the SEF and its content (the sphenoidal emissary vein [SEV]). We analyzed 1,000 computed tomography (CT) images, 170 dry skulls, 50 formalin‐fixed specimens, and three specimens (heads) following guidelines proposed by Dr. Albert L. Rhoton Jr. MD for latex injection. SEV morphology was determined by histological staining and electron microscopy. The SEF was observed in 46.8% of the CTs studied (25.4% bilateral and 21.4% unilateral), and 45.2% of the dry skulls (18.8% bilateral and 26.4% unilateral). In 9.5% of CTs and 21.1% of dry skulls there was a blind channel in the external surface of the cranial base; since there was no communication with the cranial cavity, it was not considered as the SEF. During the dissections, the SEF was found in seven individuals. In three of them, the SEV was an alternative route for venous drainage of the venous plexus of the foramen ovale. Its walls were composed of collagen fibers and its endothelium contained rhomboid cells resembling those commonly found in the superior sagittal sinus. The presence of the SEF and SEV can anatomically explain the spread of certain cranial base pathologies from or toward Meckel's cave or the cavernous sinus, and should be taken into account during procedures in the middle cranial fossa, percutaneous approaches, odontological procedures, and treatment of dural arteriovenous fistulas.

Bleeding after antiplatelet therapy for the treatment of acute coronary syndromes: a review of the evidence and evolving paradigms

ABSTRACT Introduction: Potent platelet inhibition reduces the risk of thrombotic complications including myocardial infarction and death in patients with acute coronary syndrome (ACS). Targeting different pathways involved in thrombotic processes have synergistic effects and more effectively counteract thrombosis both in the acute and long-term following an ACS. Unavoidably, more potent platelet inhibition increases the risk of bleeding. In light of the adverse prognostic implications associated with bleeding, including increased mortality, safety aspects with antiplatelet therapy have gained increased importance. Areas covered: This review aims at describing the safety of different antiplatelet agents, particularly with regards to the risk of bleeding complications, used in the management of ACS patients. New bleeding reduction strategies to enhance the safety of antiplatelet therapy are also reviewed. Expert opinion: The final goal of a well-structured antiplatelet treatment strategy is that of tackling the spectrum of ischemic risk without compromising patient safety. A simple mnemonic rule for guiding therapeutic decisions in this complex clinical scenario can be summarized with the acronym ‘ABC’, meaning the sequential process of assessing, balancing and customizing treatment strategies in individual patients on the tradeoff between bleeding and ischemic risk. This approach is recommended for maximizing the ischemic benefits, while preserving safety, with the use of antiplatelet therapy.
