Published: July 2020

Abstract
Background
Topical isotretinoin is commonly used to treat acne. However, topical isotretinoin has side effects and can hardly permeate through the stratum corneum, the most important skin barrier. Therefore, this study aimed to demonstrate the efficacy of nanoparticles as stable carriers with great curative effects, low side effects, and strong transdermal ability.

Results
In a rabbit model of hyperkeratinization, STCM-ATRA-NPs showed significant therapeutic efficacy. By contrast, negative therapeutic efficacy was observed in a golden hamster model of hyper sebum production. Scanning electron microscopy and Fourier transform infrared spectral analyses showed that nanoparticles could penetrate the stratum corneum. Western blotting demonstrated that the nanoparticles could enhance the transdermal efficacy of isotretinoin by reducing the effect of keratin and tight junction proteins. Further, nanoparticles enhanced endocytosis, thereby promoting drug penetration and absorption into the skin.

Conclusion
STCM-ATRA-NPs were demonstrated to control isotretinoin release, reducing its side effects, and efficiently permeating through the skin by reducing the effect of keratin and tight junction proteins and enhancing endocytosis.

Published: July 2020

Abstract
Background
Lateral lymph node metastasis (LLNM) is very common in papillary thyroid carcinoma (PTC). The influence of tumour location on LLNM remains controversial. The purpose of this study was to reveal the association between PTC tumours located in the upper pole and LLNM.

Methods
We reviewed a total of 1773 PTC patients who underwent total thyroidectomy with central and lateral lymph node dissection between 2013 and 2018. Patients were divided into two groups according to tumour location. Univariate and multivariate analyses were performed to identify risk factors associated with LLNM and “skip metastasis”.

Results
In the upper pole group, LLNM and skip metastasis were significantly likely to occur. Multivariate analysis showed that tumours located in the upper pole, male sex, extrathyroidal extension (ETE), central lymph node metastasis (CLNM) and tumour size were independent risk factors for LLNM, with odds ratios ([ORs], 95% confidence intervals [CIs]) of 2.136 (1.707–2.672), 1.486 (1.184–1.867), 1.332 (1.031–1.72), 4.172 (3.279–5.308) and 2.496 (1.844–3.380), respectively. Skip metastasis was significantly associated with the primary tumour location in the upper pole and age > 55 years, with ORs of 4.295 (2.885–6.395) and 2.354 (1.522–3.640), respectively.

Conclusions
In our opinion, papillary thyroid tumours located in the upper pole may have an exclusive drainage pathway to the lateral lymph nodes. When the tumour is located in the upper pole, lateral neck dissection should be evaluated meticulously.

AbstractBackgroundAberrant activation of the Hedgehog (Hh) signaling pathway is frequently observed in hepatocellular carcinoma (HCC), nevertheless, the precise molecular mechanism remains unclear. Forkhead box M1 (FOXM1), a target of the Hh pathway, is a key oncofetal transcription factor and a master cell cycle regulator. Targeting protein for Xenopus kinesin-like protein 2 (TPX2) is an oncogene critical for mitosis. However, how these molecular events affect HCC progression remains unclear.MethodsRealtime PCR, immunohistochemistry, western blotting, and analyses of datasets TCGA and Gene Expression Omnibus (GEO) were conducted to assess the expression of TPX2 and FOXM1 at the mRNA and protein levels in HCC samples or HCC cells. Expression and knockdown of TPX2 and FOXM1 were performed to assess their role in regulating HCC cell proliferation in vitro and in vivo. Dual luciferase report assay and chromosome immunoprecipitation (ChIP) were investigated to seek the FOXM1 binding sites in the promoter of TPX2.ResultsSpecific antagonists (cyclopamine and GANT61) of the Hh pathway down-regulated TPX2, whereas activation of Hh signaling stimulated TPX2 expression. Furthermore, TPX2 over-expression accelerated HCC cell proliferation when upstream events of Hh signaling were inhibited, and TPX2 knockdown significantly alleviated Sonic Hh ligand (Shh)-induced HCC cell proliferation. Reporter assays and ChIP showed that FOXM1 bound to the TPX2 promoter, confirming that TPX2 is a direct downstream target of FOXM1. Xenograft model further verified the cell function and expression regulation of TPX2 and FOXM1 in vivo. Furthermore, FOXM1 regulated TPX2 activity to drive HCC proliferation. Immunohistochemical (IHC) analysis indicated that FOXM1 and TPX2 were highly-expressed in HCC samples and cohort study revealed that FOXM1 and TPX2 may act as negative predictors for the prognosis of patients with HCC.ConclusionsTPX2 acts as a novel downstream target and effector of the Hh pathway, and Hh signaling contributes to HCC proliferation via regulating the FOXM1-TPX2 cascade, suggesting that this signaling axis may be a novel therapeutic target for HCC.Graphical abstract
BNIP3 decreases the LPS-induced inflammation and apoptosis of chondrocytes by promoting the development of autophagy
Authors: Ma Zetao , Wang Deli , Weng Jian , Zhang Sheng , Zhang Yuanshi 
Published: July 2020

Abstract
Background
Inflammation and apoptosis of chondrocytes are the pathological bases of osteoarthritis. Autophagy could alleviate the symptoms of inflammation and apoptosis. Previous study has shown that BCL2/adenovirus E1B 19 kDa protein-interacting protein 3 (BNIP3) can induce the occurrence and development of autophagy. However, it is unknown whether autophagy induced by BNIP3 can alleviate the inflammation and apoptosis of chondrocytes.

Methods
We used the lentivirus to construct the overexpression BNIP3 chondrocytes. Next, the lipopolysaccharide (LPS) was used to stimulate these cells to simulate the physiological environment of osteoarthritis. After that, the enzyme-linked immunosorbent assays (ELISA) were performed to determine the levels of tumor necrosis factor-α (TNF-α), interleukin-1 beta (IL-1β), and interleukin-6 (IL-6) and the flow cytometry was performed to detect the apoptosis rates of chondrocytes. At last, the expression of autophagy-related proteins was detected with the western blotting.

Results
The expression of BNIP3 was suppressed after treatment with LPS. However, overexpression of BNIP3 inhibited the secretion of proinflammatory factors (TNF-α, IL-1β, and IL-6) and decreased the apoptosis of chondrocytes. Furthermore, overexpression of BNIP3 led to the upregulation of autophagy-related protein expression including little computer 3 (LC3), autophagy-related protein 7 (ATG7), and Beclin-1. Application of autophagy inhibitor recovered the expression of proinflammatory factors and apoptosis rates of chondrocytes.

Conclusions
BNIP3 decreased the LPS-induced inflammation and apoptosis of chondrocytes by activating the autophagy.

Abstract
Background
Video-Assisted Thoracic Surgery (VATS) lobectomy is now considered the preferred approach at many centers for early stage lung cancer. However, it needs an adequate learning curve, and it may be challenging in non-expert hands. The aim of this study was to evaluate the effectiveness of Transcollation Technology over Traditional Electrocautery to perform hilar and mediastinal dissection during VATS lobectomy.

Methods
This is a single-center retrospective study including consecutive patients undergoing VATS lobectomy for lung cancer. Patients were divided in two groups based on whether Transcollation Technology (TT Group) or Traditional Electrocautery (TE Group) was used for hilar and mediastinal lymphadenectomy. Operative time and surgical outcome, including number of transfusions, length of chest drainage, length of hospital stay, morbidity and mortality were registered, and the inter-group differences were statistically analyzed.

Results
53 patients were included in the final analysis. The TT Group (n = 24) compared to the TE Group (n = 29) showed significant shorter operative time (75.2 ± 25.8 min versus 98.1 ± 33.3 min; p = 0.023), and reduction of length of chest tube stay (4.7 ± 0.8 days vs. 6.8 ± 1.1 days, p = 0.013) and length of hospital stay (5.3 ± 1.9 days vs. 6.8 ± 1.1 days, p = 0.007). No intraoperative or major postoperative complications were observed in either groups.

Conclusions
Transcollation Technology represents a valid alternative to standard electrocautery instruments during VATS lobectomy. It contributes to reduce the operative time and length of hospital stay. Further larger prospective studies are required to confirm our data.
Colonic perforation due to inadvertent intraperitoneal LVAD driveline placement
Authors: Shnaydman Ilya , Abdelhamid Mohamed O. , Kaufman Joyce , Lieberman Howard , Ruiz Gabriel 
Published: July 2020

Abstract
Background
Left ventricular assist devices (LVAD) are placed for patients with advanced heart failure or cardiogenic shock as destination therapy or as a bridge to cardiac transplantation. Significant complications associated with LVAD placement include bleeding, infection, pump thrombosis, right heart failure, device malfunction and stroke. The case below illustrates inadvertent intraperitoneal driveline placement causing colonic perforation and the subsequent management.

Case presentation
A 54 year old male with a history of Wolff-Parkinson-White syndrome resulting in multiple readmissions for heart failure, ultimately required placement of a left ventricular assist device (LVAD). Several weeks later, he was found to have stool draining from the driveline site. The patient was taken to the operating room for limited exploration by the Cardiothoracic Surgery team and a bowel injury was identified and repaired. Three days after this repair, stool was once again leaking from the driveline site, requiring re-exploration by the Acute Care Surgery team. Intraoperatively, the prior repair was found to be leaking and multiple intra-abdominal abscesses were discovered. The transverse colon was resected and left in discontinuity. On a planned second look operation, the LVAD driveline was relocated to be extra-peritoneal and a colostomy was formed.

Discussion and conclusion
This case demonstrates the importance of early recognition and involvement of an Acute Care Surgeon in the management of this complex problem. Appropriate treatment involves a complete exploration, source control, driveline relocation and possible fecal diversion. Although the incidence of this complication is low, it must be considered in the differential in a septic LVAD patient.

Published: July 2020

Abstract
Background
Hyperbilirubinemia is one of the common complications after cardiac surgery and is associated with increased mortality. However, to the best of our knowledge, the reports on clinical significance of postoperative severe hyperbilirubinemia in Stanford type A aortic dissection (AAD) patients were limited.

Methods
Patients who underwent surgical treatment for AAD in our center between January 2015 and December 2018 were retrospectively screened. In-hospital mortality, long-term mortality, acute kidney injury (AKI), and the requirement of continuous renal replacement therapy (CRRT) were assessed as endpoints. Univariate and multivariate regression models were employed to identify the risk factors of these endpoints.

Results
After screening, 271 patients were included in our present study. Of the included patients, 222 (81.9%) experienced postoperative AKI, and 50 (18.5%) received CRRT. The in-hospital mortality was 30.3%. The 1-year, 2-year, and 3-year cumulative mortality were 32.9, 33.9, and 35.3%, respectively. Multivariate Logistic regression analysis indicated that age (P < 0.033), AKI stage 3 (P < 0.001), the amount of blood transfusion after surgery (P = 0.019), mean arterial pressure (MAP) in the first postoperative day (P = 0.012), the use of extracorporeal membrane oxygenation (ECMO) (P = 0.02), and the peak total bilirubin (TB) concentration (P = 0.023) were independent risk factors of in-hospital mortality. The optimal cut-off value of peak TB on predicting in-hospital mortality was 121.2 μmol/L. Patients with post-operation TB ≥ 121 μmol/L was associated with worse long-term survival as well.

Conclusions
Severe post-operation hyperbilirubinemia is a common clinical situation in patients had AAD repair. In AAD patients with severe post-operation hyperbilirubinemia, older age, lower MAP, increased blood transfusion, stage 3 AKI, the use of ECMO, and the increased peak TB lead to increase in-hospital mortality.

Published: July 2020

AbstractTraditional Chinese medicine (TCM) are becoming more and more popular all over the world. However, quality issues of TCM may lead to medical incidents in practice and therefore quality control is essential to TCM. In this review, the state of TCM in European Pharmacopoeia are compared with that in Chinese Pharmacopoeia, and herbal drugs that are not considered as TCM and not elaborated by TCM working party at European Directorate for the Quality of Medicines & Health Care (EDQM) but present in both European Pharmacopoeia and Chinese Pharmacopoeias are also discussed. Different aspects in quality control of TCM including origins, identification, tests and assays, as well as sample preparation, marker selection and TCM processing are covered to address the importance of establishing comprehensive quality standard of TCM. Furthermore, advanced analytical techniques for quality control and standard establishment of TCM are also reviewed.

Authors: Wu Xia , Cai Hao , Qiu Yu , Li Jian , Zhou Dao-bin , Cao Xin-xin 
Published: July 2020

Abstract
Background
ETV6-ACSL6 is a fusion gene rarely reported in myeloid malignancies, and its clinical characteristics, proper treatment strategies, and effect on prognosis are poorly understood.

Results
Sixteen patients with the ETV6-ACSL6 fusion gene were identified, with a median age of 50 years. Twelve patients were male. Clinical diagnoses included chronic eosinophilic leukemia, not otherwise specified, acute myeloid leukemia, and other types of myeloproliferative and myelodysplastic disorders. Ten out of 12 patients had increased levels of eosinophils, and four out of five had increased levels of basophils in peripheral blood. Treatment with tyrosine kinase inhibitors was ineffective. The prognosis of the patients was poor, with seven patients dying within 1 year.

Conclusions
Patients with the ETV6-ACSL6 fusion gene mainly present with myeloproliferative and myelodysplastic disorders, typically with increased eosinophils and/or basophils and poor survival. Intensive therapies such as allogenic stem cell transplantation should be an initial consideration for eligible patients.

AbstractBackgroundDepression is a common health problem among university students. It is debilitating and has a detrimental impact on students psychosocial, emotional, interpersonal functioning and academic performance, However, there is a scarcity of information on this regard in higher education institutions in Ethiopia, so the current study was conducted to assess the prevalence of depression and its associated factors among Jimma University students.MethodsAn institution-based quantitative cross-sectional study was conducted on a total of 556 sampled students selected by a multistage stratified sampling technique. Beck Depression Inventory (BDI-II) was used to screen depression severity. Data was collected through a pretested, structured, and self-administered questionnaire. The collected data were checked manually for completeness and entered into Epidata manager Version 2.0.8.56 data entry software then exported to SPSS version 20 Statistical software for analysis. The obtained data were described using descriptive statistics as well as logistic regression analysis was done to determine the independent predictors of the outcome variable. First bivariate analysis was done and variables significant atpvalue ≤ 0.25 were entered into a multivariate logistic regression analysis to control for confounders. The significance of association was determined at a 95% confidence interval and p-value < 0.05.ResultThe prevalence of depression among the students was 28.2%. Having a mentally ill family member (OR = 2.307, 95%CI 1.055–5.049), being from the college of Social science and humanity (OR = 2.582, 95%CI 1.332–5.008), having sex after drinking (OR = 3.722, 95%CI 1.818–7.619), being hit by sexual partner (OR = 3.132, 95%CI 1.561–6.283), having childhood emotional abuse (OR = 2.167, 95%CI 1.169–4.017), having monthly pocket money between 500-999 ETB (OR = 0.450, 95% CI 0.204–0.995), and promoted academic performance (OR = 2.912, 95% CI 1.063–7.975) were significantly associated with depression.ConclusionThe prevalence of depression among Jimma University students was high and positively associated with being from the college of social science and humanity, history of a hit by a sexual partner, having a mentally ill family member, having more monthly pocket money, promoted academic performance, having sex after drinking and childhood emotional abuse. Therefore, establishing depression screening services on the campus and designing proper mental health intervention programs is recommended to tackle the problem.

Published: July 2020

Abstract
Mechanical stimuli play important roles on the growth, development, and behavior of tissue. A simple and novel paper-based in vitro tissue chip was developed that can deliver two types of mechanical stimuli—local compression and shear flow—in a programmed manner. Rat vascular endothelial cells (RVECs) were patterned on collagen-coated nitrocellulose paper to create a tissue chip. Localized compression and shear flow were introduced by simply tapping and bending the paper chip in a programmed manner, utilizing an inexpensive servo motor controlled by an Arduino microcontroller and powered by batteries. All electrical compartments and a paper-based tissue chip were enclosed in a single 3D-printed enclosure, allowing the whole device to be independently placed within an incubator. This simple device effectively simulated in vivo conditions and induced successful RVEC migration in as early as 5 h. The developed device provides an inexpensive and flexible alternative for delivering mechanical stimuli to other in vitro tissue models.

Authors: Bernal-Utrera Carlos , Gonzalez-Gerez Juan Jose , Anarte-Lazo Ernesto , Rodriguez-Blanco Cleofas 
Published: July 2020

Abstract
Background
Nonspecific chronic neck pain is a fairly common disorder that causes a great impact, and it is greatly influenced by psychosocial factors. Among a number of treatment modalities described for its management, the most common approach is based on manual therapy and specific therapeutic exercise, which have shown a moderate effect on subjects with chronic non-specific neck pain. However, the effect times of these treatments have not been accurately detailed. Our study aims to break down and compare the effects of two experimental treatments based on manual therapy and therapeutic exercise.

Methods
The short-term and mid-term changes produced by different therapies on subjects with non-specific chronic neck pain were studied. The sample was randomized divided into three groups: manual therapy, therapeutic exercise, and placebo. As dependent variables of our research, we studied (a) pain, based on the visual analog scale and the pressure pain threshold, and (b) cervical disability, through the Neck Disability Index (NDI). Outcomes were registered on week 1, week 4, and week 12. The findings were analyzed statistically considering a 5% significance level (P ≤ 0.05).

Results
No statistically significant differences (P 0.05) were obtained between the experimental groups, if they exist against the control group. Nonetheless, we found that manual therapy improved perceived pain before than therapeutic exercise, while therapeutic exercise reduced cervical disability before than manual therapy. Effect size (R2) shows medium and large effects for both experimental treatments.

Conclusion
There are no differences between groups in short and medium terms. Manual therapy achieves a faster reduction in pain perception than therapeutic exercise. Therapeutic exercise reduces disability faster than manual therapy. Clinical improvement could potentially be influenced by central processes.

Classification of geothermal systems in Madagascar
Authors: Rajaobelison M. , Raymond J. , Malo M. , Dezayes C. 
Published: July 2020

AbstractClassification schemes for geothermal energy sources have recently been improved to include the concept of geothermal play. Our comprehensive review for the island of Madagascar aims to enhance the understanding of the factors controlling the country’s geothermal energy sources. The result is the first catalogue of geothermal systems in Madagascar. The geothermal systems of six prospective areas were categorized into three classes using the geological and tectonic context combined with the temperature of the potential geothermal reservoir. The three classes are (1) graben border-fault liquid-dominated moderate-temperature (Ambilobe and Miandrivazo areas), (2) fossil magmatic liquid-dominated moderate-temperature (Ambanja, Itasy and Antsirabe areas), and (3) sedimentary liquid-dominated low-temperature (Morondava Basin). The hydrothermal resources of Madagascar are commonly associated with extensional domains referred to as geothermal plays. A conceptual model was developed for each prospective area to better understand the factors controlling the heat source, formation permeability and fluid migration. Our results can be used to guide exploration strategies and have implications for assessing and quantifying Madagascar’s geothermal potential.
