Abstract
BACKGROUND Triple negative breast cancer is more aggressive than other breast cancer subtypes and constitutes a public health problem worldwide since it has high morbidity and mortality due to the lack of defined therapeutic targets. Resistance to chemotherapy complicates the course of patients’ treatment. Several authors have highlighted the participation of nicotinic acetylcholine receptors (nAChR) in the modulation of conventional chemotherapy treatment in cancers of the airways. However, in breast cancer, less is known about the effect of nAChR activation by nicotine on chemotherapy treatment in smoking patients.
AIM To investigate the effect of nicotine on paclitaxel treatment and the signaling pathways involved in human breast MDA-MB-231 tumor cells.
METHODS Cells were treated with paclitaxel alone or in combination with nicotine, administered for one or three 48-h cycles. The effect of the addition of nicotine (at a concentration similar to that found in passive smokers’ blood) on the treatment with paclitaxel (at a therapeutic concentration) was determined using the 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. The signaling mediators involved in this effect were determined using selective inhibitors. We also investigated nAChR expression, and ATP “binding cassette” G2 drug transporter (ABCG2) expression and its modulation by the different treatments with Western blot. The effect of the treatments on apoptosis induction was determined by flow cytometry using annexin-V and 7AAD markers.
RESULTS Our results confirmed that treatment with paclitaxel reduced MDA-MB-231 cell viability in a concentration-dependent manner and that the presence of nicotine reversed the cytotoxic effect induced by paclitaxel by involving the expression of functional α7 and α9 nAChRs in these cells. The action of nicotine on paclitaxel treatment was linked to modulation of the protein kinase C, mitogen-activated protein kinase, extracellular signal-regulated kinase, and NF-κB signaling pathways, and to an up-regulation of ABCG2 protein expression. We also detected that nicotine significantly reduced the increase in cell apoptosis induced by paclitaxel treatment. Moreover, the presence of nicotine reduced the efficacy of paclitaxel treatment administered in three cycles to MDA-MB-231 tumor cells.
CONCLUSION Our findings point to nAChRs as responsible for the decrease in the chemotherapeutic effect of paclitaxel in triple negative tumors. Thus, nAChRs should be considered as targets in smoking patients.

Background
Extensive coronary artery disease (CAD) is common in diabetes mellitus. This relation between the extent of CAD and prediabetes (pDM)is less well established.
Purpose
To explore whether non-diabetic hyperglycaemia, assessed by HbA1c, is associated with extent of angiographic CAD, independent of traditional cardiovascular risk factors.
Methods
Retrospective cohort analysis of consecutive patients, without known DM undergoing coronary angiography for stable angina, who were screened for hyperglycaemia over 18 months. HbA1c was measured; pre-diabetes was defined as HbA1c 5.7-6.4%.Extent of CAD was assessed using the SYNTAX score. Presence of CAD was defined as visually estimated ≥50% luminal obstruction in arteries ≥1.5 mm diameter. Age, BMI, risk factors for CAD, HbA1c, total and LDL-cholesterol were recorded. The pre-diabetes and normal groups were compared using Mann-Whitney test for continuous variables and chi-squared test for categorical variables. Multiple logistic and linear regressions were used to assess the effect variables on SYNTAX score. Spearman rank correlation was used to assess the relation between HbA1c and SYNTAX score.
Results
1071 patients had angiograms done. 207 had DM, 19 had new diagnosis of DM and 181 missed the screening leaving 664 who had HbA1c measured. 51 poor quality angiograms were excluded from SYNTAX calculation. Data was analysed for 613 (306 normal, 307 pDM) patients. The patients with prediabetes were older, had higher prevalence of risk factors, BMI, fasting glucose and SYNTAX score. HbA1c (OR 2.07, 95% CI 1.32 to 3.25, p=0.002) and the presence of pDM (OR 1.89, 95% CI 1.32 to 2.69, p<0.001) independently predicted the presence of CAD. HbA1c (Coefficient 2.42, SE 1.09, p=0.027) and the presence of pDM (Coefficient 2.25, SE 0.92, p=0.015) independently predicted the SYNTAX score. The correlation between HbA1c and SYNTAX score was weak but significant (Spearman's coefficient 0.206, 95% CI 0.129 to 0.281, p<0.0001).
Conclusion
HbA1c predicts the extent of CAD as measured by SYNTAX score in patients without known diabetes. Presence of pre-diabetes is an independent predictor of extent of CAD.

Abstract
INTRODUCTION Recent studies suggest that immune-related cells can be recruited for anti-tumor functions as well as tumor progression and the interplay between systemic inflammation and local immune response may play a major role in the development and progression of various cancers including lung cancer. Inflammatory markers, such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII) can be used as surrogate biomarkers of host immune status. In this work, associations between neutrophils, lymphocytes, platelets, NLR, PLR, SII and overall survival (OS) are investigated in two cohorts of non-small cell lung cancer (NSCLC) patients treated with fractionated radiotherapy (RT) and stereotactic body radiation therapy (SBRT) and a cohort of small cell lung cancer (SCLC) patients treated with fractionated RT. MATERIAL AND METHODS Data from 2513 lung cancer patients were retrospectively analyzed. Baseline NLR, PLR, and SII (NLR × platelet count) were calculated from full blood test prior to RT initiation. Cox proportional hazards regression analyses were used to evaluate the association between systemic inflammation markers and known clinical factors with OS. RESULTS The two-year OS was 42%, 63%, and 62% in the NSCLC fractionated RT, SBRT, and SCLC cohort. NLR (per 1 unit: hazard ratio [HR]: 1.04, p < 0.05) and SII (per 100 × 109/L: HR: 1.01, p < 0.05) remained the strongest independent factors of OS in multivariable Cox analyses, correcting for clinical factors in early-stage and locally advanced NSCLC and SCLC patients treated with RT. DISCUSSION This single-center large-cohort study suggests that baseline NLR and SII are independent prognostic biomarkers associated with OS in locally advanced and early-stage NSCLC patients treated with either curative-intent fractionated RT or SBRT and SCLC patients treated with curative-intent fractionated RT. External validation is warranted to evaluate the utility of these biomarkers for patients' stratification and adapting new treatment approaches.

Abstract
Background Several protocols are in study to understand mechanisms of these persistent symptoms of COVID-19. The conventional echocardiography can be a good tool to detect abnormalities in the cardiovascular system induced by long COVID-19. Objective Correlation between echocardiographic parameters and symptoms of long COVID and the spontaneous evolution at one month of follow-up. Patients and methods A prospective multicentric study including a total of 630 patients diagnosed with COVID-19, 2 weeks to one month after recovering from COVID-19. Young patients without any medical history other than recent SARS-CoV2 infection are selected. A meticulous interrogation and clinical examination as well as an echocardiography are performed in all of patients. In addition to symptoms, we assessed echocardiographic parameters including initial left ventricular global longitudinal strain (initial SLG: SLGi) and after one month (SLG control: SLGc). Results Mean SLGi was −18.1 ± 2.4 in study group (−19.6 ± 1.5; P < 0.001). Forty-two patients (52.5%) had initially altered strain versus 38 patients (47.5%) with normal strain. The threshold value for SLG in our study has been established using ROC curve which was −17.95% with sensibility (52.5%) and specificity (83.7%). we found a statistically significative correlation between the initial alteration of SLG and persistent symptoms in multivariate test: dyspnea (P < 0.002); chest pain (P = 0.031). At one month of follow-up, 87.5% of patients improved their SLG. And there was a correlation between control GS value (mean SLGc was −18.91 ± 3.33; P = 0.002) associated with a marked improvement in symptoms (P = 0.001). Conclusion We reported here an original case series of SLG alteration induced by SARS-CoV2 infection that is correlated with the presence of chest pain and dyspnea. However, this affection seems to be spontaneously significantly reversible and associated with significant clinical improvement.

Abstract
The development of breast cancer is a complex process that involves the participation of different factors. Several authors have demonstrated the overexpression of muscarinic acetylcholine receptors (mAChRs) in different tumor tissues and their role in the modulation of tumor biology, positioning them as therapeutic targets in cancer. The conventional treatment for breast cancer involves surgery, radiotherapy, and/or chemotherapy. The latter presents disadvantages such as limited specificity, the appearance of resistance to treatment and other side effects. To prevent these side effects, several schedules of drug administration, like metronomic therapy, have been developed. Metronomic therapy is a type of chemotherapy in which one or more drugs are administered at low concentrations repetitively. Recently, two chemotherapeutic agents usually used to treat breast cancer have been considered able to activate mAChRs. The combination of low concentrations of these chemotherapeutic agents with muscarinic agonists could be a useful option to be applied in breast cancer treatment, since this combination not only reduces tumor cell survival without affecting normal cells, but also decreases pathological neo-angiogenesis, the expression of drug extrusion proteins and the cancer stem cell fraction. In this review, we focus on the previous evidences that have positioned mAChRs as relevant therapeutic targets in breast cancer and analyze the effects of administering muscarinic agonists in combination with conventional chemotherapeutic agents in a metronomic schedule.

Abstract
Triple negative tumors are more aggressive than other breast cancer subtypes and there is a lack of specific therapeutic targets on them. Since muscarinic receptors have been linked to tumor progression, we investigated the effect of metronomic therapy employing a traditional anti-cancer drug, paclitaxel plus muscarinic agonists at low doses on this type of tumor. We observed that MDA-MB231 tumor cells express muscarinic receptors, while they are absent in the non-tumorigenic MCF-10A cell line, which was used as control. The addition of carbachol or arecaidine propargyl ester, a non-selective or a selective subtype 2 muscarinic receptor agonist respectively, plus paclitaxel reduces cell viability involving a down-regulation in the expression of ATP “binding cassette” G2 drug transporter and epidermal growth factor receptor. We also detected an inhibition of tumor cell migration and anti-angiogenic effects produced by those drug combinations in vitro and in vivo (in NUDE mice) respectively. Our findings provide substantial evidence about subtype 2 muscarinic receptors as therapeutic targets for the treatment of triple negative tumors.

Abstract
AIMS To evaluate the impact of peer review and contouring workshops on reducing uncertainty in target volume delineation for lung cancer radiotherapy. MATERIALS AND METHODS Data from two lung cancer target volume delineation courses were analysed. In total, 22 trainees in clinical oncology working across different UK centres attended these courses with priori experience in lung cancer radiotherapy. The courses were made up of short presentations and contouring practice sessions. The participants were divided into two groups and asked to first individually delineate (IND) and then individually peer review (IPR) the contours of another participant. The contours were discussed with an expert panel consisting of two consultant clinical oncologists and a consultant radiologist. Contours were analysed quantitatively by measuring the volume and local distance standard deviation (localSD) from the reference expert consensus contour and qualitatively through visual analysis. Feedback from the participants was obtained using a questionnaire. RESULTS All participants applied minor editing to the contours during IPR, leading to a non-statistically significant reduction in the mean delineated volume (IND = 140.92 cm3, IPR = 125.26 cm3, P = 0.211). The overall interobserver variation was similar, with a localSD of 0.33 cm and 0.38 cm for the IND and IPR, respectively (P = 0.848). Six participants (29%) carried out correct major changes by either including tumour or excluding healthy tissue. One participant (5%) carried out an incorrect edit by excluding parts of the tumour, while another observer failed to identify a major contour error. The participants' level of confidence in target volume delineation increased following the course and identified the discussions with the radiologist and colleagues as the most important highlights of the course. CONCLUSION IPR could improve target volume delineation quality among trainee oncologists by identifying most major contour errors. However, errors were also introduced after IPR, suggesting the need to further discuss major changes with a multidisciplinary team.

Abstract
Infective endocarditis remains an important clinical entity with an incidence of 1.7–10/100 000 person years (Marks et al, 2015). Despite improvements in health care, it still results in significant morbidity and in-hospital mortality approaches 16% (Marks et al, 2015). There are likely multiple causes including late diagnosis, poor response to therapy and the challenges in identifying the causative pathogen and instigating the correct treatment. This is particularly the case for causative organisms that are difficult to culture or identify using routine laboratory methods.
An example of this is Streptococcus intermedius, which belongs to the S. milleri group along with other two species (S. anginosus group and S. constellatus). It is a commensal organism that can turn into an opportunistic pathogen (Whiley et al, 1992). It is a rare cause of infective endocarditis and may initially present with abscesses in the liver, spleen or brain which may mimic fungal infection (Woo et al, 2004; Rashid et al, 2007; Tran et al, 2008). Difficulty in identifying this organism has led to the development of molecular testing to aid diagnosis. To the authors' knowledge, there are very few cases in the literature of infective endocarditis caused by S. intermedius that have been confirmed using 16S polymerase chain reaction (Woo et al, 2004). This article describes a patient presenting with S. intermedius infective endocarditis which was diagnosed using this method.

Abstract
Background International guidelines recommend using basal insulin in patients with type-2 diabetes mellitus if glycaemic target cannot be attained on non-insulin anti-diabetic drugs. Available choices of basal insulin include intermediate-acting neutral protamine Hagedorn (NPH) insulin and long-acting insulin analogues like insulin glargine U100. Despite clear advantages of glargine U100, the existing practice in Hong Kong still favours NPH insulin due to lower immediate drug costs. Objectives The objective of this study was to assess the cost-effectiveness of insulin glargine U100 compared to NPH insulin in patients with type-2 diabetes uncontrolled with non-insulin anti-diabetic agents alone in Hong Kong. Methods The IQVIA™ Core Diabetes Model (CDM) v9.0 was used to conduct the cost-effectiveness analysis of glargine U100 versus NPH. Baseline characteristics were collected from the Hong Kong Diabetes Registry. Efficacy rates were extracted from a published study comparing glargine U100 and NPH in Asia, utilities from published literature, and costs constructed using the Hong Kong Hospital Authority (HA) Gazette (public healthcare setting). The primary outcome was an incremental cost-effectiveness ratio (ICER). Results Insulin glargine U100 resulted in an ICER of HKD 98,663 per Quality Adjusted Life Year (QALY) gained. The incremental gains in QALY and costs were 0.217 years and HKD 21,360 respectively. Results from scenario and probabilistic sensitivity analyses were consistent with that from base case analysis. Conclusion Insulin glargine U100 is a cost-effective treatment for patients with type 2 diabetes compared to NPH insulin in setting in Hong Kong. This was mainly driven by the significantly lower rates of hypoglycaemia of insulin glargine U100 than NPH insulin.

Abstract
Canopy air curtain (CAC) technology has been developed by the National Institute for Occupational Safety and Health (NIOSH) for use on continuous miners and subsequently roof bolting machines in underground coal mines to protect operators of these machines from overexposure to respirable coal mine dust. The next logical progression is to develop a CAC for shuttle cars to protect operators from the same overexposures. NIOSH awarded a contract to Marshall University and J.H. Fletcher to develop the shuttle car CAC. NIOSH conducted laboratory testing to determine the dust control efficiency of the shuttle car CAC. Testing was conducted on two different cab configurations: a center drive similar to that on a Joy 10SC32AA cab model and an end drive similar to that on a Joy 10SC32AB cab model. Three different ventilation velocities were tested-0.61, 2.0, 4.3 m/s (120, 400, and 850 fpm). The lowest, 0.61 m/s (120 fpm), represented the ventilation velocity encountered during loading by the continuous miner, while the 4.3 m/s (850 fpm) velocity represented ventilation velocity airflow over the shuttle car while tramming against ventilation airflow. Test results showed an average of the dust control efficiencies ranging from 74 to 83% for 0.61 m/s (120 fpm), 39%-43% for 2.0 m/s (400 fpm), and 6%-16% for 4.3 m/s (850 fpm). Incorporating an airflow spoiler to the shuttle car CAC design and placing the CAC so that it is located 22.86 cm (9 in.) forward of the operator improved the dust control efficiency to 51%-55% for 4.3 m/s (850 fpm) with minimal impact on dust control efficiencies for lower ventilation velocities. These laboratory tests demonstrate that the newly developed shuttle car CAC has the potential to successfully protect shuttle car operators from coal mine respirable dust overexposures.
