Published: January 2020

Abstract
Background
Perioperative hyperglycemia is associated with poor outcomes yet evidence to guide intraoperative goals and treatment modalities during non-cardiac surgery are lacking. End-stage liver disease is associated with altered glucose homeostasis; patients undergoing liver transplantation display huge fluctuations in blood glucose (BG) and represent a population of great interest. Here, we conduct a randomized trial to compare the effects of strict versus conventional glycemic control during orthotopic liver transplant (OLT).

Methods
Following approval by the Institutional Review Board of the University of Michigan Medical School and informed consent, 100 adult patients undergoing OLT were recruited. Patients were randomized to either strict (target BG 80–120 mg/dL) or conventional (target BG 180–200 mg/dL) BG control with block randomization for diabetic and nondiabetic patients. The primary outcomes measured were 1-year patient and graft survival assessed on an intention to treat basis. Graft survival is defined as death or needing re-transplant (www.unos.org). Three and 5-year patient and graft survival, infectious and biliary complications were measured as secondary outcomes. Data were examined using univariate methods and Kaplan-Meir survival analysis. A sensitivity analysis was performed to compare patients with a mean BG of ≤120 mg/dL and those > 120 mg/dL regardless of treatment group.

Results
There was no statistically significant difference in patient survival between conventional and strict control respectively;1 year, 88% vs 88% (p-0.99), 3 years, 86% vs 84% (p- 0.77), 5 years, 82% vs 78. % (p-0.36). Graft survival was not different between conventional and strict control groups at 1 year, 88% vs 84% (p-0.56), 3 years 82% vs 76% (p-0.46), 5 years 78% vs 70% (p-0.362).

Conclusion
There was no difference in patient or graft survival between intraoperative strict and conventional glycemic control during OLT.

Sciatic obturator femoral technique versus spinal anaesthesia in patients undergoing surgery for fixation of open tibial fractures using Ilizarov external fixator. A randomised trial
Authors: Shokri Hoda , Kasem Amr A. 
Published: January 2020

Abstract
Background
Peripheral nerve block is preferable for lower extremity surgery because it sufficiently blocks pain pathways at different levels providing excellent anaesthesia at the site of surgery. We designed this study to compare the efficacy and safety of SOFT block (sciatic-obturator-femoral technique) compared with spinal anaesthesia in patients undergoing surgery for fixation of open tibial fractures using Ilizarov external fixator.

Methods
One hundred and seven patients ASA I, II scheduled for fixation of open tibial fractures using Ilizarov external fixator. The patients were randomly allocated to receive either spinal anaesthesia or SOFT block. In spinal anaesthesia group, patients received spinal anaesthesia with hyperbaric bupivacaine 0.5% (7. 5-10mg). In SOFT group, patients received SOFT block with bupivacaine 0.25%. Primary endpoint included the duration of analgesia. The secondary endpoints included patient satisfaction scores, visual analogue scores, incidence of adverse events as vomiting, systemic toxicity from local anaesthetic drug and time to first effect of the techniques.

Results
The duration of SOFT block and time to first analgesic dose in SOFT group was significantly longer (p < 0.001). There was no significant difference between the study groups regarding satisfaction scores, the incidence of cardiovascular collapse, seizures and paraesthesia. Pain scores were significantly lower in SOFT group at 3,6,12 h postoperative (p < 0.001). The time to the first effect was significantly longer in SOFT group (p < 0.001).

Conclusion
SOFT is a feasible technique of local anaesthesia for control of postoperative pain with unremarkable adverse events compared with spinal anaesthesia, in patients undergoing fixation of tibial fractures using Ilizarov external fixator.

Abstract
Background
As an essential component of multimodal analgesia approaches after total knee arthroplasty (TKA), local infiltration analgesia (LIA) can be classified into peri-articular injection (PAI) and intra-articular injection (IAI) according to administration techniques. Currently, there is no definite answer to the optimal choice between the two techniques. Our study aims to investigate analgesic efficacy and safety of PAI versus IAI in patients receiving simultaneous bilateral TKA.

Methods
This randomized controlled trial was conducted from February 2017 and finished in July 2018. Sixty patients eligible for simultaneous bilateral total knee arthroplasty were randomly assigned to receive PAI on one side and IAI on another. Primary outcomes included numerical rating scale (NRS) pain score at rest or during activity at 3 h, 6 h, 12 h, 24 h, 48 h, and 72 h following surgery. Secondary outcomes contained active or passive range of motion (ROM) at 1, 2, and 3 days after surgery, time to perform straight leg raise, wound drainage, operation time, and wound complications.

Results
Patients experienced lower NRS pain scores of the knee receiving PAI compared with that with PAI during the first 48 h after surgery. The largest difference of NRS pain score at rest occurred at 48 h (PAI: 0.68, 95%CI[0.37, 0.98]; IAI: 2.63, 95%CI [2.16, 3.09]; P < 0.001); and the largest difference of NRS pain score during activity also took place at 48 h (PAI: 2.46, 95%CI [2.07, 2.85]; IAI: 3.90, 95%CI [3.27, 4.52]; P = 0.001). PAI group had better results of range of motion and time to perform straight leg raise when compared with IAI group. There were no differences in operation time, wound drainage, and wound complication.

Conclusion
PAI had the superior performance of pain relief and improvement of range of motion to IAI. Therefore, the administration technique of peri-articular injection is recommended when performing local infiltration analgesia after total knee arthroplasty.

Trial registration
The trial was retrospectively registered in the Chinese Clinical Trial Registry as ChiCTR1800020420 on 29th December, 2018.

Correlation between multiple cerebral aneurysms and a rare type of segmental duplication of the middle cerebral artery
Authors: Stojanović Nebojša N. , Kostić Aleksandar , Mitić Radisav , Berilažić Luka 
Published: January 2020

Abstract
Background
Connection between the duplication of the middle cerebral artery (DMCA) and the presence of multiple aneurysms has been described in a small number of cases.

Case presentation
The presence of a rare type of DMCA associated with cerebral aneurysms was diagnosed in 56 year old woman after a rupture of an aneurysm on the dorsal segment of the DMCA. .. The presence of equal diameters of branches of the DMCA and anterior cerebral artery (ACA) could be recorded as trifurcation of the carotid internal artery (ICA). However, due to the anastomosis of the DMCA branches in the area of the M2 segment, the recorded anatomical change represented a segmental duplication of MCA. Three aneurysms that were directly related to the segmental DMCA were diagnosed.

Conclusions
Anatomical variation by type of segmental DMCA is a rare subtype of DMCA. The presence of multiple aneurysms associated with this type of anatomical variation in MCA indicates their high hemodynamic instability.

AbstractBackgroundThe high HIV prevalence in South Africa may potentially be shaping the local adverse drug reaction (ADR) burden. We aimed to describe the prevalence and characteristics of serious ADRs at admission, and during admission, to two South African children’s hospitals.MethodsWe reviewed the folders of children admitted over sequential 30-day periods in 2015 to the medical wards and intensive care units of each hospital. We identified potential ADRs using a trigger tool developed for this study. A multidisciplinary team assessed ADR causality, type, seriousness, and preventability through consensus discussion. We used multivariate logistic regression to explore associations with serious ADRs.ResultsAmong 1050 patients (median age 11 months, 56% male, 2.8% HIV-infected) with 1106 admissions we found 40 serious ADRs (3.8 per 100 drug-exposed admissions), including 9/40 (23%) preventable serious ADRs, and 8/40 (20%) fatal or near-fatal serious ADRs. Antibacterials, corticosteroids, psycholeptics, immunosuppressants, and antivirals were the most commonly implicated drug classes. Preterm neonates and children in middle childhood (6 to 11 years) were at increased risk of serious ADRs compared to infants (under 1 year) and term neonates: adjusted odds ratio (aOR) 5.97 (95% confidence interval 1.30 to 27.3) and aOR 3.63 (1.24 to 10.6) respectively. Other risk factors for serious ADRs were HIV infection (aOR 3.87 (1.14 to 13.2) versus HIV-negative) and increasing drug count (aOR 1.08 (1.04 to 1.12) per additional drug).ConclusionsSerious ADR prevalence in our survey was similar to the prevalence found elsewhere. In our setting, serious ADRs were associated with HIV-infection and the antiviral drug class was one of the most commonly implicated. Similar to other sub-Saharan African studies, a large proportion of serious ADRs were fatal or near-fatal. Many serious ADRs were preventable.
Lumbar vertebral osteoradionecrosis: a rare case report with 10-year follow-up and brief literature review

Published: January 2020

Abstract
Background
Osteoradionecrosis (ORN) is a complication that occurs after radiotherapy for head or neck malignancies. ORN of the spine is rare, with only few cases affecting the cervical spine reported to date. To our knowledge, no case of lumbar ORN has been reported. We report a rare case of ORN in the lumbar spine that occurred 2 years after radiotherapy and perform a literature review.

Case presentation
We present a case of lumbar ORN that occurred 2 years after radiotherapy for gallbladder carcinoma. The patient was successfully treated conservatively and followed up for > 10 years.

Conclusions
ORN of the spine is a rare complication of radiotherapy. Spinal ORN is clinically described as a chronic disease with a slow onset. The most common presenting symptom of spinal ORN is pain. However, as ORN progresses, spinal kyphosis and instability can lead to neurological compression and thus to induced myelopathy or radiculopathy. Treatment of spinal ORN is comprehensive, including orthosis, medication, hyperbaric oxygen therapy, surgery, and new treatment combinations of pentoxifylline and tocopherol. The surgical rate for spinal ORN is relatively high.
End-of-life decision making by Austrian physicians - a cross-sectional study

Published: January 2020

AbstractBackgroundAustria has recently been embroiled in the complex debate on the legalization of measures to end life prematurely. Empirical data on end-of-life decisions made by Austrian physicians barely exists. This study is the first in Austria aimed at finding out how physicians generally approach and make end-of-life therapy decisions.MethodsThe European end-of-life decisions (EURELD) questionnaire, translated and adapted by Schildmann et al., was used to conduct this cross-sectional postal survey. Questions on palliative care training, legal issues, and use of and satisfaction with palliative care were added. All Austrian specialists in hematology and oncology, a representative sample of doctors specialized in internal medicine, and a sample of general practitioners, were invited to participate in this anonymous postal survey.ResultsFive hundred forty-eight questionnaires (response rate: 10.4%) were evaluated. 88.3% of participants had treated a patient who had died in the previous 12 months. 23% of respondents had an additional qualification in palliative medicine. The cause of death in 53.1% of patients was cancer, and 44.8% died at home. In 86.3% of cases, pain relief and / or symptom relief had been intensified. Further treatment had been withheld by 60.0%, and an existing treatment discontinued by 49.1% of respondents. In 5 cases, the respondents had prescribed, provided or administered a drug which had resulted in death. 51.3% of physicians said they would never carry out physician-assisted suicide (PAS), while 30.3% could imagine doing so under certain conditions. 38.5% of respondents supported the current prohibition of PAS, 23.9% opposed it, and 33.2% were undecided. 52.4% of physicians felt the legal situation with respect to measures to end life prematurely was ambiguous. An additional qualification in palliative medicine had no influence on measures taken, or attitudes towards PAS.ConclusionsThe majority of doctors perform symptom control in terminally ill patients. PAS is frequently requested but rarely carried out. Attending physicians felt the legal situation was ambiguous. Physicians should therefore receive training in current legislation relating to end-of-life choices and medical decisions. The data collected in this survey will help political decision-makers provide the necessary legal framework for end-of-life medical care.

Published: January 2020

AbstractThe study presented in this work emerged as a result of a multiyear regional geochemical survey based on low-density topsoil sampling and the ensuing geochemical atlas of Croatia. This study focuses on the Dinaric part of Croatia to expound the underlying mechanisms controlling the mobilities and variations in distribution of potentially harmful elements as observed from different environmental angles. Although serious environmental degradation of the vulnerable karst soil landscapes was expected to occur chiefly through the accumulation of various heavy metals, the most acute threat materialized through the soil acidification (Al-toxicity) affecting the entire Dinaric karst area. This picture surfaced from the analysis of all three investigated discriminant function models employing the abovementioned environmental criteria selected autonomously with respect to the evaluated soil geochemistry, namely, geologic setting, regional placement and land use. These models are presented by not only the characteristic discriminant-function diagrams but also a set of appropriate mathematically derived geochemical maps disclosing the allocations of potential threats to the karst soil landscapes posed by soil acidity.

Abstract
Background and objectives
NF-kB, SIRT1 and systemic inflammation factors including hs-CRP, IL-6 and TNF-α accelerate atherosclerosis pathogenesis. Our purpose was to evaluate the effect of daily supplementation of three-gram cinnamon on plasma levels of NF-kB, SIRT, hs-CRP, IL-6 and TNF-α among type 2 diabetes patients.

Subjects and methods
A randomized, double blind, and controlled clinical trial was performed with 44 adult patients who were 25 to 70 years old with type 2 diabetes, randomized to two intervention (n = 22) and control (n = 22) groups differing by daily three grams cinnamon supplementation and placebo for 8 weeks, respectively. The plasma levels of NF-kB, SIRT, hs-CRP, IL-6 and TNF-α were measured by ELISA assay at the beginning and end of the study.

Results
After 8-week intervention, 39 subjects (n = 20 in the cinnamon and n = 19 in the placebo groups) ended up the trial. It was not observed significant difference in levels of hs-CRP (P = 0.29), TNF-α (P = 0.27), IL-6 (P = 0.52), and Sirtuin-1 (P = 0.51) in between group comparison. While, the result showed significant difference in levels of NF-kB (P = 0.02) between groups. As well as, in among group comparison, there was not observed significant differences except in hs-CRP (P = 0.008) in placebo group.

Conclusions
This study elucidated that cinnamon supplementation has no beneficial effects in reduction of NF-kB, SIRT1, hs-CRP, IL-6 and TNF-α levels in type 2 diabetes patients which have a considerable role in development of atherogenesis.

Published: January 2020

AbstractHepatocellular carcinoma (HCC) is the most commonmalignancy. Exsome plays a significant role in the elucidation of signal transduction pathways between hepatoma cells, angiogenesis and early diagnosis of HCC. Exosomes are small vesicular structures that mediate interaction between different types of cells, and contain a variety of components (including DNA, RNA, and proteins). Numerous studies have shown that these substances in exosomes are involved in growth, metastasis and angiogenesis in liver cancer, and then inhibited the growth of liver cancer by blocking the signaling pathway of liver cancer cells. In addition, the exosomal substances could also be used as markers for screening early liver cancer. In this review, we summarized to reveal the significance of exosomes in the occurrence, development, diagnosis and treatment of HCC, which in turn might help us to further elucidate the mechanism of exosomes in HCC, and promote the use of exosomes in the clinical diagnosis and treatment of HCC.

Published: January 2020

AbstractThe nuclear speckle-type pox virus and zinc finger (POZ) protein (SPOP), a representative substrate-recognition subunit of the cullin-RING E3 ligase, has been characterized to play a dual role in tumorigenesis and cancer progression. Numerous studies have determined that SPOP suppresses tumorigenesis in a variety of human malignancies such as prostate, lung, colon, gastric, and liver cancers. However, several studies revealed that SPOP exhibited oncogenic function in kidney cancer, suggesting that SPOP could exert its biological function in a cancer type-specific manner. The role of SPOP in thyroid, cervical, ovarian, bone and neurologic cancers has yet to be determined. In this review article, we describe the structure and regulation of SPOP in human cancer. Moreover, we highlight the critical role of SPOP in tumorigenesis based on three major categories: physiological evidence (animal models), pathological evidence (human cancer specimens) and biochemical evidence (downstream ubiquitin substrates). Furthermore, we note that SPOP could be a promising therapeutic target for cancer treatment.
Hypertriglyceridemia triggered acute pancreatitis in pregnancy – diagnostic approach, management and follow-up care

Published: January 2020

AbstractAcute pancreatitis is a pregnancy complication potentially lethal for both the mother and fetus, occurring most frequently in the third trimester or early postpartum. Hypertriglyceridemia may be the cause of important disease in pregnant patients. Patients with triglyceride levels exceeding 1000 mg/dL are at increased risk of developing severe pancreatitis. Diagnostic criteria and management protocols are not specific for pancreatitis complicating pregnancy. Other causes of acute abdominal pain must be considered in the differential diagnosis. Decision-making in the obstetric context is challenging and bears potential legal implications. Pre-pregnancy preventive measures and prenatal antilipemic treatment are mandatory in high risk patients.
