    9 vs. 4.5%; odds ratio 67, 95% confidence interval 6.606-2041,

     = 0.003). Infants developing F-NEC achieved full feeds earlier (22.5 vs. 19.8 days,

     = 0.025) on univariate but not multivariate analysis. There was no difference in the rates of NEC and F-NEC among infants receiving breast milk (standard or fortified) or formula (standard or increased caloric density;

     = 0.235).

     Among premature neonates with NEC, reaching full volume feedings was associated with a nearly 70-fold increased risk of F-NEC. Assuming it was possible to predict an infant’s development of NEC, alternative feeding regimens might reduce the risk of F-NEC in this population.

     Pelvic neuroblastoma (NB) is a rare entity and occurs in 2 to 5% of all NBs. Surgery in the pelvic area is-even for the experienced oncological surgeon-technically challenging, as injuries of bladder and/or rectal innervation may carry lifelong consequences for the patient. Several studies have proven the impact of image-defined risk factors (IDRFs) for outcome, complications and extent of resection in NB; however, the specific role of IDRF in pelvic NB has not been investigated yet.

     Patient charts were retrospectively evaluated for International Staging System stage, IDRF status, MYCN amplification, and outcome parameters.

     Between 2003 and 2019, 277 NBs were surgically resected in the department of pediatric surgery of Dr. von Hauner Children’s Hospital. Out of these, 11 patients (3.9%) had pelvic NB. Evaluation of the preoperative imaging showed two patients without IDRF (stage L1) and eight patients in stage L2. One patient had stage M according to distant metastasis. Patients without IDRF underwent complete macroscopical resections, whereas complete tumor removal was not possible without mutilation in patients with IDRF. At time point of diagnosis, only patients with IDRF had functional neurological problems. Three patients developed perioperative complications; all of them had at least one IDRF. Three patients developed local recurrence during the course of the disease, all of them had at least one IDRF.

     Our results indicate on a preliminary level the importance of IDRF as a prognostic tool for surgical removal of pelvic NB.

     Nicotine is an established neuroteratogen, and prenatal tobacco exposure alters the structure of the developing nervous system. An association between prenatal tobacco exposure and impaired neurologic function is less well established. We examine the association between prenatal tobacco exposure and childhood neurodevelopment among infants born preterm.

     Secondary analysis of a multicenter randomized controlled trial assessing the benefits of magnesium sulfate for the prevention of cerebral palsy in preterm infants. Women were included if they delivered a singleton and nonanomalous infant before 37 weeks. Exposure was any self-reported prenatal tobacco use. Primary outcome was the original trial composite outcome of moderate or severe cerebral palsy at 2 years of age, or stillbirth, or infant death by 1 year of age. Secondary outcomes included components of the composite and mild cerebral palsy at 2 years, Bayley Scales of Infant Development II motor and mental scores, death before two years, and use of e associated with impaired vision.

    · Tobacco exposure is not associated with impaired neurodevelopment in this preterm population.. · Prenatal tobacco exposure is associated with increased need for corrective lenses.. · Tobacco use in pregnancy may be a risk factor for poorer visual acuity in children..

     Severe maternal morbidity (SMM) has increased by 45% in the United States and is estimated to affect up to 1.5% of all deliveries. Research has not yet been conducted that demonstrates a benefit to multidisciplinary review of SMM. The aim of our study was to determine if standardized, routine review of the cases of SMM by a multidisciplinary committee results in a reduction of potentially preventable cases of SMM.

     A retrospective cohort study of all women admitted for delivery at Cedars-Sinai Medical Center from March 1, 2012 to September 30, 2016. Our cohort was separated into two groups a preintervention group composed of women admitted for delivery prior to the implementation of the obstetric Quality and Peer Review Committee (OBQPRC), and a postintervention group where the committee had been well established. Cases of confirmed SMM were presented to a multidisciplinary research committee, and the committee determined whether opportunities for improvement in care existed. The groups were compared witotentially preventable SMM.. · This is the first study to demonstrate the benefit of routine review of SMM..

    · Benefit to routine review of SMM has not been demonstrated.. · Routine review of SMM is associated with 36% reduction in potentially preventable SMM.. · This is the first study to demonstrate the benefit of routine review of SMM..

     The Emergency Severity Index (ESI) version 4 is a 5-level triage system (1 being the highest acuity and 5 being the lowest acuity) used in the emergency department (ED). Our goal of the study was to compare rates of readmission according to ESI in postpartum women.

     This was a secondary analysis of a retrospective cohort study of all women who presented to the ED within 6 weeks after cesarean delivery. The acuity level was assigned by triage nurses at the time of triage presentation. Our primary outcome was postpartum readmission. To examine if the addition of blood pressure to vital sign abnormalities would improve the prediction for readmission, we created a modified ESI. We identified women who had an ESI of level 3 and reassigned to a modified ESI of level 2 if blood pressure was in the severe range. Receiver operating characteristic curves with area under the curve (AUC) were created and compared between ESI and modified ESI.

     Of 439 women, ESI distribution was 0.2% ESI 1, 23.7% ESI 2, 56.0% ESI 3· Consideration of a severe range blood pressure significantly improved the prediction of readmission..Life-threatening hemoptysis (LTH) is any amount of hemoptysis that causes significant hemodynamic decompensation or respiratory distress which may lead to death if left untreated. While the amount of hemoptysis that qualifies as massive hemoptysis has continued to be debated, any amount between 100 to 1,000 mL/day is considered significant. Up to 15% cases of hemoptysis are LTH and need urgent life-saving intervention. Understanding of pulmonary vascular anatomy is of paramount importance to manage LTH. The goal of treatment lies in airway protection, appropriate oxygenation, and prevention of exsanguination. Once the airway is stabilized, a quick diagnosis and control of bleeding site is targeted. This chapter highlights current practices and approach to LTH including medical management, bronchoscopic approach, and advanced therapies such as bronchial artery embolization and surgical resection. We review situations, such as bronchiectasis, vascular malformation, diffuse alveolar hemorrhage, and tracheostomy bleed and specific approach to management of these conditions in a systematic and evidence-based manner.Successful microvascular reconstruction of head and neck defects requires the ability to safely identify, isolate, and utilize recipient vessels. To date, however, a comprehensive review of the anatomy and techniques relevant to the available anatomic regions has not been undertaken. This review covers the relevant clinical anatomy of the anterior triangle, posterior triangle, submandibular region, intraoral region, preauricular region, chest, and arm, taking particular care to highlight the structures that are crucial to identify while performing each dissection. Finally, a step-by-step technique for safely dissecting the recipient vessels at each site is provided.

     Autologous breast reconstruction (ABR) has grown in popularity due to improved aesthetic and long-term patient reported outcomes, but data regarding sensory reinnervation of autologous flaps remain limited. Traditionally, the lateral cutaneous branch of the fourth intercostal nerve has been used for flap neurotization, but the use of the anterior cutaneous branch of the intercostal nerves (ACB) offer a more optimal location to the microsurgical field when using internal mammary vessels for the microanastomosis. This study aimed to evaluate the optimum ACB recipient site level for sensory nerve coaptation in ABR.

     Twelve hemi-chests were dissected from six fresh cadaveric females. Costal cartilages were removed and the anterior cutaneous intercostal nerve (ACB) and the lateral (subcutaneous) division of the anterior cutaneous branch (LACB) of the intercostal nerve were exposed. Anatomical measurements were recorded, and nerve samples were evaluated histologically with carbonic anhydrase staining to differve branches for recipient site coaptation in ABR.

     This study provides anatomical and histological basis to determine the optimum recipient site choice for sensory coaptation in microsurgical breast reconstruction. This would aid in operative decision-making regarding the ideal recipient anterior cutaneous intercostal nerve branches for recipient site coaptation in ABR.

     Patients requiring microsurgical defect reconstruction are highly susceptible to intraoperative hypothermia, given oftentimes long operative times and exposure of large skin surface areas. While the impact of hypothermia has been extensively studied across various surgical fields, its role in the setting of microsurgical free flap reconstruction remains elusive. This study evaluates the effects of hypothermia on outcomes of free flap reconstructions.

     Within 7 years, 602 patients underwent 668 microvascular free flap reconstructions. The cases were divided into two groups regarding the minimal core body temperature during free flap surgery hypothermia (HT; < 36.0°C) versus normothermia (NT; ≥36.0°C). The data were retrospectively screened for patients’ demographics, perioperative details, flap survival, surgical complications, and outcomes.

     Our data revealed no significant difference with regard to the rate of major and minor surgical complications, or the rate of revision surgery between both groure should range between 36 and 36.5°C during free flap surgery as a pragmatic guideline.

    Pituitary adenomas are common benign tumors of the pituitary gland with an overall estimated prevalence of 16.7%. As per the revised World Health Organization (WHO) classification, these tumors are identified by their histological subtypes and are designated by their pituitary cell lineage instead of the hormone they produce. The lactotroph adenoma is the most common subtype of hormone-producing pituitary adenoma. Surgery is the mainstay of treatment, but complications are encountered. So far, there is no reported study evaluating individualized homeopathic intervention in pituitary adenoma in peer-reviewed journals.

    This case study describes a case of functional lactotroph microadenoma with history of failed surgical treatment and heavy intrasellar hemorrhage occurring during the surgery.

    was prescribed as an individualized homeopathic medicine on the basis of symptoms-hemorrhagic complication during surgical procedure and aggravation of headache thereafter.

    There was a marked subjective improvement along with complete tumor regression, as evidenced by repeat magnetic resonance imaging scans. The Modified Naranjo Criteria total score was +10 out of a possible +13, providing some evidence to attribute the clinical outcome with the homeopathic intervention.

    This case study reconfirms the association between increased frequency of headaches and pituitary hemorrhage among cases of lactotroph adenoma. It also suggests that individualized homeopathic treatment may be helpful in pituitary adenomas with increased risk of complications such as intrasellar hemorrhage.

     The aim of this study was to measure the load on the lateral and medial aspects of the proximal radio-ulnar joint during extension of the carpus.

     This was an

    biomechanical study.

     Twenty-two cadaveric Greyhound thoracic limbs were used.

     Twenty-two paired thoracic limbs were used. The olecranon was attached to a custom jig with the foot resting on a stationary anvil. Load sensors were inserted into the proximal radio-ulnar joint, between the radial head and the lateral coronoid process, and between the radial head and the medial coronoid process. Specimens were tested under compression with measurements taken at 0, 4, 9 and 13.5 mm of axial displacement. Data collected at each point included forces on the specimen and medial and lateral coronoid processes as well as the angle of carpal joint extension.

     A linear mixed effects model relating load on the specimen and carpal joint extension angle had an R-squared value of 0.66, and load at the level of the medial coronoid process and angle of carpal extension had an R-squared value of 0.61. There was a significant difference in the loads measured on the lateral and medial coronoid processes at all angles (

     < 0.0001).

     Extension of the carpus results in asymmetric loading of the proximal radio-ulnar joint.

     The findings of this study show that loading of the medial coronoid process may be more complex than originally thought and supports the future investigation of novel management and therapeutic options for affected patients.

     Direct oral anticoagulants (DOACs) are prescribed for atrial fibrillation (AF) and venous thromboembolism (VTE) and both occur more frequently in obese patients. Outcomes from DOAC trials included few individuals ≥ 120 kg leading to uncertainty whether high body weight (BW) reduces DOAC concentrations.

     This article investigates the relationship between factor Xa (FXa) inhibitor concentrations, BW, and renal function, and compares them in high BW patients with unselected populations.

     Consecutive patients in two United Kingdom centers, weighing ≥ 120 kg receiving 5 mg twice daily apixaban or 20 mg once daily rivaroxaban for AF or VTE were prospectively included. Peak or trough concentrations were measured using specific chromogenic assays, expressed in mean or median (5th-95th percentiles). On-therapy range was the interval from the 5th percentile trough concentration to the 95th percentile peak concentration.

     One hundred patients were included; age range 23 to 78 years, 31% were women, 58% had AF, creatinine clearance range 67 to 474 mL/min. Median BW was 139 kg, and 84% had body mass index (BMI) ≥ 40 kg/m

    . DOAC peak and trough concentrations varied from 44 to 727 and 14 to 299 ng/mL, respectively. There was no linear relationship between FXa inhibitor concentrations at peak or trough and BW or BMI, and creatinine clearance. Apixaban troughs in AF and rivaroxaban peaks in VTE were lower than in unselected populations. However, only two trough concentrations were below the expected range, and 109/116 were within the on-therapy range.

     These data indicated that obese or high BW patients generally achieve therapeutic FXa inhibitor concentrations. However, further investigations assessing clinical outcomes are required.

Excess mortality and/or transfer to intensive care unit according to CAHA staging.Four recently published randomized controlled trials have informed the care of patients with stable ischemic heart disease. The purpose of this clinical focus article is to offer a summary and critical appraisal of the recent evidence. We aim to aid clinicians in the translation of the trial evidence to patient care.Fucosylated chondroitin sulfate (FCS) polysaccharide isolated from sea cucumber has potent anticoagulant activity. Based on its resistance to the enzymes present in vertebrates, it may serve as an anticoagulant and shows antithrombotic effects when delivered through gastro-resistant (GR) tablets. However, due to the multiple plasma targets of FCS polysaccharide in the coagulation pathway, bleeding can occur after its oral administration. In the current study, we used FCS oligomers, in particular a mixture of oligosaccharides having 6 to 18 saccharide units, as the active ingredient in GR microcapsules for oral anticoagulation. In a Caco-2 model, the FCS oligomers showed higher absorption than native FCS polysaccharides. Oral administration of FCS oligomer-GR microcapsules provided a dose-dependent, prolonged anticoagulant effect with a selective inhibition of the intrinsic coagulation pathway when compared with subcutaneous administration of FCS oligomers or oral administration of unformulated FCS oligomers or native FCS-GR microspheres. Continued oral administration of FCS oligomer-GR microcapsules did not result in the accumulation of oligosaccharides in the plasma. Venous thrombosis animal models demonstrated that FCS oligomers delivered via GR microcapsules produced a potent antithrombotic effect dependent on their anticoagulant properties in the plasma, while oral administration of unformulated FCS oligomers at the same dose exhibited a weaker antithrombotic effect than the formulated version. Oral administration of FCS oligomer-GR microcapsules resulted in no bleeding, while oral administration of native FCS-GR microcapsules resulted in bleeding (p  less then  0.05). Our present results suggest that a FCS oligomer-GR microcapsule formulation represents an effective and safe oral anticoagulant for potential clinical applications.

    Systemic sclerosis (SSc) is an autoimmune disease characterized by the overproduction of collagen leading to fibrosis of the skin and internal organs. Interstitial lung disease (ILD) is one of the major causes of death in patients with SSc. Exercise tolerance can be investigated by cardio-pulmonary exercise testing (CPET). First-line therapies in patients with SSc associated with ILD (SSc-ILD) include cyclophosphamide and mycophenolate mofetil (MMF). The aim of this study was to evaluate the response of patients with SSc-ILD to MMF by means of CPET.

    Ten consecutive SSc patients were enrolled in this study. All SSc patients underwent clinical evaluation, echocardiography, pulmonary function tests, high-resolution computed tomography (HRCT) and CPET at baseline and after 2 years of therapy with MMF.

    After 24 months of treatment with MMF (target dose 1500mg twice daily), forced vitality capacity, diffusing capacity of the lungs for carbon monoxide and systolic pulmonary arterial pressure had not improved sith SSc-ILD. These preliminary results need to be confirmed in large randomized studies.

    We aimed to assess the diagnostic performance of CT in patients with a negative first RT-PCR testing and to identify typical features of COVID-19 pneumonia that can guide diagnosis in this case.

    Patients suspected of COVID-19 with a negative first RT-PCR testing were retrospectively revalued after undergoing CT. CT was reviewed by two radiologists and classified as suspected COVID-19 pneumonia, non-COVID-19 pneumonia or negative. The performance of both first RT-PCR result and CT was evaluated by using sensitivity (SE), specificity (SP), positive predictive value (PPV), negative predictive value (NPV) and area under the curve (AUC) and by using the second RT-PCR test as the reference standard. CT findings for confirmed COVID-19 positive or negative were compared by using the Pearson chi-squared test (P values < 0.05) RESULTS Totally, 337 patients suspected of COVID-19 underwent CT and nasopharyngeal swabs in March 2020. Eighty-seven out of 337 patients had a negative first RT-PCR result; of these, 68 repeated RT-PCR testing and were included in the study. The first RT-PCR test showed SE 0, SP = 100%, PPV = NaN, NPV = 70%, AUC = 50%, and CT showed SE = 70% SP = 79%, PPV = 86%, NPV = 76%, AUC = 75%. The most relevant CT variables were ground glass opacity more than 50% and peripheral and/or perihilar distribution.

    Negative RT-PCR test but positive CT features should be highly suggestive of COVID-19 in a cluster or community transmission scenarios, and the second RT-PCR test should be promptly requested to confirm the final diagnosis.

    GLP-1 receptor agonists, such as exenatide, have been proven to attenuate nonalcoholic fatty liver disease (NAFLD) in vivo and in vitro. However, the efficiency of exenatide had interindividual differences. PNPLA3 is a major susceptibility gene for NAFLD and its I148M polymorphism increases the risk of all disorders of the NAFLD spectrum. Whether this variant contributes to variability in exenatide response is still unclear.

    PNPLA3 148I knockin HepG2 cells were constructed using the Cas9/sgRNA system. Oil Red O staining combined with TG quantification was used to evaluate lipid accumulation. Western blotting and qRT-qPCR were conducted, respectively, to measure the protein and mRNA expression of lipid metabolic and endoplasmic reticulum (ER) stress-related inflammatory markers. PNPLA3 I148M was genotyped in type 2 diabetics using Sanger sequencing. The exenatide-induced changes in liver fat content and other clinical parameters were compared between PNPLA3 I148M genotypes.

    Lipid deposition increased in both PNPLA3 148I/I and 148M/M HepG2 cells treated with palmitoleic acid, while cells with 148M/M had a higher TG content than those with 148I/I. Exendin-4 treatment was showed to be more significant in 148I/I cells than in 148M/M cells in terms of reducing the intrahepatic fat content, inhibiting SREBP-1c and ER stress-related inflammation, and activating AMPK-ACC lipid oxidation pathway. In patients with type 2 diabetes, 24-week treatment with exenatide improved liver fat content in patients carrying PNPLA3 148I/I better than in patients with 148M/M.

    PNPLA3 I148M might modify the anti-NAFLD response to exenatide.

Twenty-five patients who were treated by laser pilonidoplasty for pilonidal sinus (group 1) and 25 patients who were treated by platelet-rich plasma in addition to laser pilonidoplasty (group 2) at this clinic were included in the study. Patients were classified according to the Irkorucu and Adana Numune’s classification and treatment concept. Duration of stay of the patients in the hospital, time to start daily activities, duration of wound healing, recurrence, and complications were evaluated. Among the 50 patients included in the study, 41 (%82) were males and 9 (%18) were females. The mean age was 25.6 ± 2.4 years and 24.8 ± 3.8 years in groups 1 and 2, respectively. The locations of the pilonidal sinus were similar in the two groups. No statistically significant differences were found in the duration of hospital stay, duration of the procedure, time to return to work, and complication rates between the two groups. Nevertheless, duration of wound healing was 6.1 ± 2.3 and 4.1 ± 0.9 weeks in groups 1 and 2, respectively, and was shorter in group 2. Duration of wound healing was statistically significantly different in the two groups. We concluded in this study that application of platelet-rich plasma in addition to laser pilonidoplasty significantly shortens the time of wound healing.Photobiomodulation therapy (PBMT) has been used to improve the physical performance of individuals with advanced age; however, there are no studies in the literature that support the application of light-emitting diode (LED) therapy for the muscular performance of individuals with diabetes mellitus who show a decline in functionality. The aim of the study was to analyze the acute effects of PBMT on strength and functional performance in type 2 diabetic individuals. Sixty-three volunteers were recruited and randomized into five groups control (C), sham (S), red LED (R), infrared LED (IR), and red LED + infrared LED (R + IR). On the first day, the volunteers were evaluated using the time up and go (TUG), the 6-min walk test (6MWT), and isokinetic dynamometer of the ankle. In the following 3 days, groups R, IR, R + IR, and S returned for application of PBMT bilaterally, with 180 J of energy on each leg. On the fifth day, a reassessment was performed. There was no statistical difference between groups for the variables of the isokinetic dynamometer, TUG, and 6MWT. Analysis of the size of the clinical effect for the isokinetic variables showed that there was no pattern among the effects observed. There is a moderate effect in favor of R, IR, and R + IR in relation to C for the TUG and a moderate effect of R + IR in relation to C for the 6MWT. The PBMT applied for a short period does not bring important gains for the muscular performance and functionality of diabetic individuals.Neuroinflammation contributes to the pathogenesis of early brain injury induced by subarachnoid hemorrhage (SAH). Previous reports have demonstrated that triggering receptor expressed on myeloid cells 1 (TREM-1) regulates inflammatory response caused by ischemic stroke or myocardial infarction. However, whether TREM-1 could modulate neuroinflammation after SAH remains largely unknown. Here, using a mouse model of SAH, we found that the expression of TREM-1 was mainly located in microglia cells and increased to peak at 24 h following SAH. Then, TREM-1 antagonist or mimic was intranasally administrated to investigate its effect on SAH. TREM-1 inhibition with LP17 improved neurological deficits, mitigated brain water content, and preserved brain-blood barrier integrity 24 h after SAH, whereas recombinant TREM-1, a mimic of TREM-1, deteriorated these outcomes. In addition, LP17 administration restored long-term sensorimotor coordination and cognitive deficits. Pharmacological blockade of TREM-1 reduced TUNEL-positive and FJC-positive neurons, and CD68-stained microglia in ipsilateral cerebral cortex. Neutrophil invasion was inhibited as protein level of myeloperoxidase (MPO), and MPO-positive cells were both decreased. Moreover, we found that LP17 treatment ameliorated microglial pyroptosis by diminishing levels of N-terminal fragment of GSDMD (GSDMD-N) and IL-1β production. Mechanistically, both in vivo and in vitro, we depicted that TREM-1 can trigger microglial pyroptosis via activating NLRP3 inflammasome. In conclusion, our results revealed the critical role of TREM-1 in neuroinflammation following SAH, suggesting that TREM-1 inhibition might be a potential therapeutic approach for SAH.Stroke is a major cause of death and disability worldwide. Yet therapeutic strategies available to treat stroke are very limited. There is an urgent need to develop novel therapeutics that can effectively facilitate functional recovery. The injury that results from stroke is known to induce neurogenesis in penumbra of the infarct region. There is considerable interest in harnessing this response for therapeutic purposes. This review summarizes what is currently known about stroke-induced neurogenesis and the factors that have been identified to regulate it. Additionally, some key studies in this field have been highlighted and their implications on future of stroke therapy have been discussed. There is a complex interplay between neuroinflammation and neurogenesis that dictates stroke outcome and possibly recovery. This highlights the need for a better understanding of the neuroinflammatory process and how it affects neurogenesis, as well as the need to identify new mechanisms and potential modulators. Neuroinflammatory processes and their impact on post-stroke repair have therefore also been discussed.Acute respiratory infection (ARI) is a major cause of morbidity and mortality worldwide. Most of these infections are caused by viruses. Infections pose as important triggers of acute episodes of chronic respiratory diseases (CRD). This study sought to evaluate the frequency and circulation profile of respiratory viruses among ARI symptomatic patients and completely asymptomatic children in Midwest Brazil. The study enrolled symptomatic children with and without ARI symptoms. During 1 year, 225 nasal respiratory samples were obtained from patients aged 4-14 years old. The samples were screened by multiplex nested-PCR for 16 common respiratory viruses. From 225 samples, 42 had at least one virus detected. Samples from four different patients had multiple viruses detected. The viral detection rate in symptomatic (20.1%) and asymptomatic patients (14.8%) showed no significant difference. The most frequent viruses detected were rhinovirus (28.6%), FLUA (11.9%), adenovirus (11.9%), human bocavirus (HBoV) (11.9%), and respiratory syncytial virus (RSV) antigenic group A (9.5%). Monthly detection rate was higher during the rainy season. RSVs were detected during the months with higher rainfall indexes and higher air humidity, while FLU and HBoV were detected during the winter months. The obtained results reinforce the importance of viral pathogens in pediatric population, emphasizing similar viral occurrence in symptomatic and asymptomatic children.In this study, two kinds of Artemisia plant, Artemisia campestris L. and Artemisia herba-alba Asso., collected from different locations in Djelfa province, Algeria, were subjected to an instrumental neutron activation analysis (INAA) in order to determine their essential and toxic elements for the first time. The obtained results for both types revealed the existence of twenty-one elements, namely, As, Ba, Br, Ca, Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Na, Rb, Sb, Sc, Sm, Sr, Yb, and Zn, where, the elements K, Ca, Fe, and Na respectively showed a significant concentration. On the other hand, the tolerable daily intake (TDI) of the studied plants for an adult person per day was within the tolerance limits imposed by the World Health Organization (WHO). Hence, these findings might therefore be used to offer scientific basis for an optimum usage of the studied plants and so enriches the database of medicinal herbs.A diligent, systematic, regular review of aggregate safety data is essential, particularly early after vaccine introduction, as this is when safety signals not identified during clinical development may emerge. In October 2017, the US Centers for Disease Control and Prevention Advisory Committee on Immunization Practices recommended the adjuvanted recombinant zoster vaccine (RZV; Shingrix, GSK) as the preferred vaccine for preventing herpes zoster (HZ) and related complications in immunocompetent adults aged ≥ 50 years. Subsequently, GSK experienced an unprecedented high demand for RZV. In this methodology paper, we summarize the enhanced measures undertaken to assess RZV safety during its early post-marketing experience in the USA, Canada and Germany. In addition to the routine signal-detection methods already in place for all vaccines, GSK established tailored and enhanced safety monitoring for RZV based on aggregate data of spontaneous reports and manufacturing data. Proactive, near real-time detection and evaluation of signals was a key objective. A dedicated in-house signal-detection tool customized for RZV was employed on a weekly (rather than the routine monthly) basis, allowing for a centralized, more frequent review of data on a single web-based platform. We also identified the background incidence rates of preselected medical events of interest in the first countries to introduce RZV (USA, Canada and Germany) to perform observed-to-expected analyses. This approach may offer a solution to the challenges associated with the assessment and monitoring of vaccine safety in an efficient and timely manner in the context of high vaccine uptake.The outbreak of coronavirus disease 2019 (COVID-19) has spread rapidly around the world. As of May 30, 2020, a total of 84 568 confirmed COVID-19 cases have been recorded in China, with a mortality rate of approximately 5.5%. Taizhou is a prefecture-level city in Zhejiang Province. A total of 146 cases were diagnosed in this epidemic, with a fatality rate of 0%. This condition is due to the establishment of an „Internet +” diagnosis and treatment model based on online medical application (APP), telemedicine, WeChat service, and consultation hotline in Taizhou. Taizhou led in opening the „COVID-19 Prevention and Treatment Special Line” in China, which is conducive to pre-hospital screening, suppressing social panic, and clinical support. Hospitals also carried out related online lectures and popularization of science. We summarize Taizhou’s COVID-19 prevention and control experience with telemedicine features, with a view to providing reference for the control of the epidemic at home and abroad.Intake of probiotic bacteria may improve or preserve insulin sensitivity. Fetuin-A and sestrin 3 have emerged as promising candidate biomarkers for crucial roles in insulin signaling pathway. Therefore, the effect of oral supplementation with the probiotic bacterium Lactobacillus delbrueckii subsp. lactis PTCC1057 on proteins involved in insulin signaling pathway was investigated in normal and streptozotocin (STZ)-induced diabetic mice. The 6-8-week-old female mice were divided into a non-diabetic control, diabetic control, and diabetic experimental and non-diabetic experimental groups (5 mice each group). Diabetic and non-diabetic experimental groups treated with 3 × 107 CFU mL-1 L. delbrueckii subsp. lactis PTCC1057 by gavage feeding approach daily for 28 days. Serum glucose, fetuin-A, and sestrin 3 levels were measured by standard methods. The result showed that oral administration of L. delbrueckii significantly decreased serum glucose in comparison to diabetic control group (P = 0.01). Serum fetuin-A level was higher in diabetic control group than non-diabetic group and oral administration of L. delbrueckii subsp. lactis PTCC1057 significantly decreased fetuin-A level in diabetic experimental group in comparison with non-diabetic groups (P = 0.001). Sestrin 3 level significantly was lower in diabetic control group than non-diabetic control group (P = 0.03) and it significantly increased in diabetic experimental group in comparison with diabetic control group after intervention of L. delbrueckii subsp. lactis PTCC1057 (P = 0.02). The results show that feeding the STZ-induced diabetic mice with L. delbrueckii subsp. lactis PTCC1057 terminated to decrease in fasting blood glucose and fetuin-A level and increase in serum sestrin 3 level. Therefore, the L. delbrueckii subsp. lactis PTCC1057 can be considered as excellent candidate for future studies on diabetes mellitus.Mesenchymal stem cells (MSCs) are multi-potent cells characterized by long term self-renewal and by potential for differentiation into cells of different mesenchymal tissue types such as fibroblasts, osteocytes, chondrocytes, and adipocytes. Their unique properties offer broad therapeutic potentials. Bone marrow has been used as the most common MSCs source, but it is gradually going to be replaced by adipose tissue which showed to contain more MSCs per unit than the bone marrow and clinical application of MSCs procured from the adipose tissue have been demonstrating at least similar results. Post-burn scars result frequently in severe both functional and aesthetic impairments in restitution and rehabilitation periods of the burn disease. Despite extensive research in the last decades, the exact mechanisms of scar formation remains unclear. The development of post-burn scars is influenced by multiple factors such as initial depth of the burn, methods of burn wound therapy, duration of the open wound until finaructed scar and required volume of transferred fat. Isolation of MSCs following procurement was provided by the Central Tissue Bank cell culture laboratory which is one of the parts of the burn department. The average time of scars duration was 79 months, ranging from 6 to 216 months. The postburns scars were assessed clinically according to Vancouver Scar Scale (VSS) prior to surgery, including photo documentation, and re-evaluated after 6 months following MSCs application. As the results have shown, the average VSS score before treatment was 7.88 points ranging from 4 to 11 points. The average VSS 6 months after surgical procedure and MSCs application was 2.34 points ranging from 1 to 4 points. According to the results obtained, the favourable effect of adipose tissue derived autologous MSCs application on scar remodelling following surgical reconstruction of post-burn scars could be promising.Here, we aim at developing a novel biomatrix from decellularized bovine spinal meninges for tissue engineering and regenerative medicine applications. Within this concept, the bovine spinal meninges were decellularized using 1% Triton X-100 for 48 h, and residual nuclear content was determined with double-strand DNA content analysis and agarose gel electrophoresis. The major matrix components such as sulfated GAGs and collagen before and after the decellularization process were analyzed with DMMB, hydroxyproline assay and SDS-PAGE. Subsequently, the native bovine spinal meninges (nBSM) and decellularized BSM (dBSM) were physiochemically characterized via ATR-FTIR spectroscopy, TGA, DMA and tensile strength test. The dsDNA content in the nBSM was 153.39 ± 53.93 ng/mg dry weight, versus in the dBSM was 39.47 ± 4.93 ng/mg (n = 3) dry weight and DNA fragments of more than 200 bp in length were not detected in the dBSM by agarose gel electrophoresis. The sulfated GAGs contents for nBSM and dBSM were observed to be 10.87 ± 1.2 and 11.42 ± 2.01 μg/mg dry weight, respectively. The maximum strength of dBSM in dry and wet conditions was found to be 19.67 ± 0.21 MPa and 13.97 ± 0.17 MPa, while nBSM (dry) was found to be 26.26 ± 0.28 MPa. MTT, SEM, and histology results exhibited that the cells attached to the surface of dBSM, and proliferated on the dBSM. In conclusion, the in vitro preliminary study has demonstrated that the dBSM might be a proper and new bioscaffold for tissue engineering and regenerative medicine applications.Non-Herlitz junctional epidermolysis bullosa (JEB-nH), an autosomal recessive bullous genodermatosis, is characterized by generalized skin blistering from birth onward, dental anomalies, universal alopecia and nail dystrophy. The underlying defect is mutation of the COL17A1 gene encoding the type XVII collagen, resulting in losing structure for attachment of basal epithelial cells to the matrix. In present study, we described one case of congenitally affected female child aged 10 years, with skin blistering. Dermatologic examination revealed sparse, mild blisters on the face and hand, with profound enamel pitting of the teeth. Skin biopsy from proband’s bullous skin displayed subepidermal bulla formation without acantholysis. The immunofluorescence of anti-type XVII collagen antibody staining showed loss of type XVII collagen staining at the basement membrane zone. A combination of whole exome sequencing (WES) and Sanger sequencing revealed the novel heterozygous mutations (c.4324C>T;p.Q1442* and c.1834G>C;p.G612R) in COL17A1 gene, which could be associated with the observed JEB-nH. One allele had a novel nonsense mutation (c.4324C>T;p.Q1442*), resulting in nonsense-mediated mRNA decay and truncated collagen XVII; the other allele had a novel missense mutation of c.1834G>C;p.G612R in exon 22, causing a glycine-to-arginine substitution in the Gly-X-Y triple helical repeating motifs and decreasing the thermal stability of collagen XVII. Our findings indicate that the genetic test based on WES can be useful in diagnosing JEB-nH patients. The novel pathogenic mutations identified would further expand our understanding of the mutation spectrum of COL17A1 gene in association with the inherited blistering diseases.Choosing proper perfusates as contrast agents is an important aspect for postmortem magnetic resonance angiography (PMMRA). However, in this emerging field, the number of suitable kinds of liquid is still very limited. The objective of this research is to compare MR images of oleic acid (OA) with paraffin oil (PO) in vitro and in ex situ animal hearts, in order to evaluate the feasibility to use OA as a novel contrast agent for PMMRA. In vitro, OA, PO and water (control) were introduced into three tubes separately and T1weighted-spin echo (T1w-SE) and T2w-SE images were acquired on a 1.5T MR scanner. In the second experiment, OA and PO were injected into left coronary artery (LCA) and left ventricle (LV) of ex situ bovine hearts and their T1w-SE, T2w-SE, T1w-multipoint Dixon (T1w-mDixon) and 3DT2w-mDixon images were acquired. The overall results indicate that OA may have a potential to be used as a dual (T1 and T2 based) contrast agent for PMMRA when proper sequence parameters are utilized. However, as the pilot study was based on limited number of animal hearts, more researches using OA in cadavers are needed to validate our findings.Renal cancer is a common genitourinary malignance, of which clear cell renal cell carcinoma (ccRCC) has high aggressiveness and leads to most cancer-related deaths. Identification of sensitive and reliable biomarkers for predicting tumorigenesis and progression has great significance in guiding the diagnosis and treatment of ccRCC. Here, we identified 2397 common differentially expressed genes (DEGs) using paired normal and tumor ccRCC tissues from GSE53757 and The Cancer Genome Atlas (TCGA). Then, we performed weighted gene co-expression network analysis and protein-protein interaction network analysis, 17 candidate hub genes were identified. These candidate hub genes were further validated in GSE36895 and Oncomine database and 14 real hub genes were identified. All the hub genes were up-regulated and significantly positively correlated with pathological stage and histologic grade of ccRCC. Survival analysis showed that the higher expression level of each hub gene tended to predict a worse clinical outcome. ROC analysis showed that all the hub genes can accurately distinguish between tumor and normal samples, and between early stage and advanced stage ccRCC. Moreover, all the hub genes were positively associated with distant metastasis, lymph node infiltration, tumor recurrence and the expression of MKi67, suggesting these genes might promote tumor proliferation, invasion and metastasis. Furthermore, the functional annotation demonstrated that most genes were enriched in cell-cycle related biological function. In summary, our study identified 14 potential biomarkers for predicting tumorigenesis and progression, which might contribute to early diagnosis, prognosis prediction and therapeutic intervention.The optimal assisted reproductive treatment strategy for infertile women with unilateral tubal obstruction remains uncertain. To investigate the role of intrauterine insemination (IUI) in the treatment of infertile women with unilateral tubal occlusion, the data of 148 couples were retrospectively collected and analyzed. Seventy-eight infertile women with unilateral occlusion diagnosed by hysterosalpingography (HSG) were categorized as the study group and 70 others with unexplained infertility as the control group. The study group was divided into a proximal occlusion subgroup and a mid-distal occlusion subgroup for further analysis. The main outcomes, namely the clinical pregnancy rate (CPR), ongoing pregnancy rate (OPR), and live birth rate (LBR) per cycle, were analyzed. Our results showed a tendency of lower CPR, OPR, and LBR in the study group than in the control group, without statistical significance. Further investigations revealed that the unilateral proximal occlusion subgroup had similar CPR, OPR, and LBR as the control group, while the unilateral mid-distal occlusion subgroup had significantly lower CPR (5.1% vs. 20.0%, P=0.035), OPR (5.1% vs. 20.0%, P=0.035), and LBR (5.1% vs. 20.0%, P=0.035) than the control group. In conclusion, the clinical outcomes of IUI were worse in patients with unilateral tubal occlusion than in those with unexplained infertility. This might be primarily caused by the worse outcome of patients with unilateral mid-distal tubal occlusion instead of proximal occlusion.Mechanisms of pruritus are implicated in the dysregulation of the metabolites in the spinal cord. We investigated pruritus behavioral testing in three groups of young adult male C57Bl/6 mice, including one group treated with normal saline, while the other groups intradermally injected with α-Me-5-HT (histamine-independent pruritogen), compound 48/80 (histamine-dependent pruritogen) at the nape skin of the neck, respectively. Proton nuclear magnetic resonance spectroscopy (MRS) was used to compare spinal metabolites from the vertebral cervical among three groups, and to study the association of spinal metabolite ratio and pruritus intensity. The MRS-measured N-acetylaspartate-to-myoinositol ratio (NAA/Ins) was significantly correlated with the number of scratches between normal saline group and 48/80 group or α-Me-5-HT group (both P less then 0.0001), indicating that NAA/Ins may be a robust surrogate marker of histamine-independent/dependent pruritogen. There was significant difference in Glu/Ins between normal saline group and 48/80 group (P=0.017), indicating that Glu/Ins may be a surrogate marker of histamine-dependent pruritogen, while GABA/Ins was highly significantly different between normal saline group and α-Me-5-HT group (P=0.008), suggesting that GABA/Ins may be a surrogate marker of histamine-independent pruritogen. MRS may reflect the extent of pruritus intensity elicited by α-Me-5-HT and compound 48/80 with sensitivity similar to the number of scratches, and above potential markers need to be further validated in pre-clinical and clinical treatment trials.Studies have shown that periodontal pathogens can enter the bloodstream, causing a series of reactions that can lead to a variety of systemic diseases. Epidemiological investigations also found a tight correlation between periodontitis (PD) and osteoporosis. This study aimed to further explore the effect of periodontal pathogens on bone volume fraction like bone tissue and mass, and explain the relationship between PD and osteoporosis. Sprague Dawley rats (female, 16 weeks old) were divided into the wild-type (WT) control group (n=9) and PD group (n=9). After eight weeks, periodontal tissues and ligatures, the fourth lumbar vertebra, the femur, the tibia, and blood were extracted and analyzed by micro-computed tomography (micro-CT), hematoxylin and eosin (H&E) staining, tartrate-resistant acid phosphatase (TRAP) staining, polymerase chain reaction (PCR), and enzyme-linked immunoassay (ELISA), respectively. We found that the bone mass of the lumbar vertebra, femur, and tibia was decreased in the PD group. The number of osteoclasts was higher in bone tissue in the PD group than in the WT group (P0.05). In addition, we detected several periodontal pathogens, such as Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans, and Fusobacterium nucleatum, in blood samples from rats in the PD group. These findings suggest that periodontal pathogens can enter the blood circulation from periodontal tissue, promote a systemic inflammation response, and subsequently reduce systemic bone density.With delayed childbearing in women, preservation of fertility is an important issue for reproductive-age patients with epithelial ovarian carcinoma (EOC). Fertility-sparing surgery (FSS) can be considered in patients with early-stage disease in order to preserve fertility and improve quality of life. In order to evaluate oncological safety, attitudes toward childbearing and reproductive outcomes in women with EOC who underwent FSS, this multicenter retrospective study was conducted. Between January 2005 and December 2014, total of 87 young women with FIGO stage I EOC were included, with their clinicopathologic parameters in relation to disease-free survival (DFS) and overall survival (OS) assessed. Attitudes toward childbearing, ovarian function and fertility were studied in women undergoing FSS (n=36). As a result, in contrast to radical surgery, FSS did not affect prognosis by Kaplan-Meier curves (log-rank test; DFS P=0.484; OS P=0.125). However, two of the three recurrence cases and both death cases were in FSS group stage IC. All women undergoing FSS resumed regular menstrual periods after chemotherapy. Only 16 (44.44%) had tried to conceive, and 17 pregnancies occurred in 15 (93.75%) women. Among 20 women who did not attempt conception, the most common reason was not being married (70%), followed by already having children (15%). In summary, FSS is considered safe in young women with stage IA EOC. Regular menstruation and good obstetric outcomes can be achieved. This study also provides some insight into the attitudes and social factors regarding fertility in EOC patients.Microsurgical free tissue transfer is still playing an important role in lower extremity reconstruction. Finding a suitable recipient artery for anastomosis is critical in the microsurgical procedure, especially in an extensive wound, or in a complex trauma combined with vascular injury. From April 2014 to March 2018, we retrospectively reviewed patients with traumatic/post-traumatic, oncologic, and electrical wounds in the lower extremity. Those treated with muscle feeding artery as recipient vessels were included. The latissimus dorsi (LD) muscle free flap, anterior lateral thigh (ALT) perforator free flap, and deep inferior epigastric perforator (DIEP) free flap were raised. The muscle feeding arteries to vastus lateral muscle and to medial head of gastrocnemius muscle, concomitant veins, and great saphenous vein were used as recipient vessels. Injuries included in the study were caused by tumour in 2 cases, car accident in 3 cases, crushing in 3 cases, burns in one case, and electrical injury in one case.
