Abstract
Abstract
Aims
Junctional adhesion molecule A (JAM-A/F11R) is a cell adhesion molecule. Membrane associated JAM-A mediates platelet aggregation, secretion, adhesion, and spreading. Plasma levels of JAM-A are elevated in hypertension and atherosclerosis. This study was designed to investigate the impact of JAM-A single nucleotide polymorphisms (SNPs) on circulatory JAM-A levels and prognosis in patients with symptomatic coronary artery disease (CAD).
Methods and results
JAM-A SNP analysis (JAM-A F11R rs2774276 and rs790056) was performed in 943 patients with symptomatic CAD. All patients were tracked for all-cause death (ACD), myocardial infarction (MI), and ischemic stroke (IS) for 1080 days. The primary combined endpoint (CE) was defined as a composite of ACD and/or MI and/or IS. Secondary endpoints were defined as the single events of ACD and MI. Homozygote carriers of the minor allele (F11R rs2774276 and rs790056) showed significantly worse event-free survival for MI when compared with major allele carriers (Log rank = 0.011 and log rank = 0.031, respectively). No significant differences could be shown for the CE and ACD. Of note, in multivariate analysis, both SNPs were significantly and independently associated with MI. Furthermore, serum levels of soluble JAM-A were elevated in homozygote carriers of minor allele when compared to major allele carriers. Finally, serum levels of soluble JAM-A were significantly elevated in patients with MI when compared to stable CAD (p=0.036).

Conclusion
JAM-A SNPs are associated with prognosis in patients with symptomatic coronary artery disease. Furthermore, JAM-A SNPs might influence serum concentration of soluble JAM-A. Finally, serum concentration of soluble JAM-A is higher in patients with myocardial infarction when compared to stable coronary artery disease. These findings suggest JAM-A as a valuable biomarker for risk stratification and tailoring therapies in patients with coronary artery disease.

Abstract
AIM Published prognostic scores for metastatic colorectal cancer (mCRC) are based on data from highly selected patient subgroups with specified first-line treatments and may not be applicable to routine practice. We have therefore developed and validated the metastatic colorectal cancer score (mCCS) to predict overall survival (OS) for patients with mCRC. METHOD A total of 1704 patients from the prospective, multicentre cohort study Tumour Registry Colorectal Cancer were separated into learning (n = 796) and validation (n = 908) samples. Using a multivariate Cox regression model, the six-factor mCCS was established. RESULTS The six independent prognostic factors for survival are as follows: two or more metastatic sites at the start of first-line treatment, tumour grading ≥ G3 at primary diagnosis, residual tumour classification ≥ R1/unknown, lymph node ratio (of primary tumour) ≥ 0.4, tumour stage ≥ III/unknown at primary diagnosis and KRAS status mutated/unknown. The mCCS clearly separated the learning sample into three risk groups: zero to two factors (low risk), three factors (intermediate risk) and four to six factors (high risk). The prognostic performance of the mCCS was confirmed in the validation sample and additionally stratified a large sample of patients with known (K)RAS mutation status. CONCLUSION The novel prognostic score, mCCS, clearly defines three prognostic groups for OS at start of first-line therapy. For oncologists, the mCCS represents a simple and easy-to-apply tool for routine clinical use, as it is based on objective tumour characteristics and can assist with treatment decision-making and communication of the prognosis to patients.

Abstract
BACKGROUND Transgender individuals sometimes seek gender confirmation treatments (GCT), including hormone therapy (HT) and/or surgical change of the chest and genitalia ("top" and "bottom" gender confirmation surgeries). These treatments may ameliorate distress resulting from the incongruence between one's physical appearance and gender identity. AIM The aim was to examine the degree to which individuals' body-gender congruence, body image satisfaction, depression, and anxiety differed by GCT groups in cohorts of transmasculine (TM) and transfeminine (TF) individuals. METHODS The Study of Transition, Outcomes, and Gender is a cohort study of transgender individuals recruited from 3 health plans located in Georgia, Northern California, and Southern California; cohort members were recruited to complete a survey between 2015-2017. Participants were asked about: history of GCT; body-gender congruence; body image satisfaction; depression; and anxiety. Participants were categorized as having received: (1) no GCT to date; (2) HT only; (3) top surgery; (4) partial bottom surgery; and (5) definitive bottom surgery. OUTCOMES Outcomes of interest included body-gender congruence, body image satisfaction, depression, and anxiety. RESULTS Of the 2,136 individuals invited to participate, 697 subjects (33%) completed the survey, including 347 TM and 350 TF individuals. The proportion of participants with low body-gender congruence scores was significantly higher in the "no treatment" group (prevalence ratio [PR] = 3.96, 95% CI 2.72-5.75) compared to the definitive bottom surgery group. The PR for depression comparing participants who reported no treatment relative to those who had definitive surgery was 1.94 (95% CI 1.42-2.66); the corresponding PR for anxiety was 4.33 (95% CI 1.83-10.54). CLINICAL TRANSLATION Withholding or delaying GCT until depression or anxiety have been treated may not be the optimal treatment course given the benefits of reduced levels of distress after undergoing these interventions. CONCLUSIONS Strengths include the well-defined sampling frame, which allowed correcting for non-response, a sample with approximately equal numbers of TF and TM participants, and the ability to combine data on HT and gender confirmation surgeries. Limitations include the cross-sectional design and the fact that participants may not be representative of the transgender population in the United States. Body-gender congruence and body image satisfaction were higher, and depression and anxiety were lower among individuals who had more extensive GCT compared to those who received less treatment or no treatment at all.

Abstract
PURPOSE The Study of Transition, Outcomes and Gender (STRONG) was initiated to assess the health status of transgender people in general and following gender-affirming treatments at Kaiser Permanente health plans in Georgia, Northern California and Southern California. The objectives of this communication are to describe methods of cohort ascertainment and data collection and to characterise the study population. PARTICIPANTS A stepwise methodology involving computerised searches of electronic medical records and free-text validation of eligibility and gender identity was used to identify a cohort of 6456 members with first evidence of transgender status (index date) between 2006 and 2014. The cohort included 3475 (54%) transfeminine (TF), 2892 (45%) transmasculine (TM) and 89 (1%) members whose natal sex and gender identity remained undetermined from the records. The cohort was matched to 127 608 enrollees with no transgender evidence (63 825 women and 63 783 men) on year of birth, race/ethnicity, study site and membership year of the index date. Cohort follow-up extends through the end of 2016. FINDINGS TO DATE About 58% of TF and 52% of TM cohort members received hormonal therapy at Kaiser Permanente. Chest surgery was more common among TM participants (12% vs 0.3%). The proportions of transgender participants who underwent genital reconstruction surgeries were similar (4%-5%) in the two transgender groups. Results indicate that there are sufficient numbers of events in the TF and TM cohorts to further examine mental health status, cardiovascular events, diabetes, HIV and most common cancers. FUTURE PLANS STRONG is well positioned to fill existing knowledge gaps through comparisons of transgender and reference populations and through analyses of health status before and after gender affirmation treatment. Analyses will include incidence of cardiovascular disease, mental health, HIV and diabetes, as well as changes in laboratory-based endpoints (eg, polycythemia and bone density), overall and in relation to gender affirmation therapy.

Abstract
BACKGROUND Sodium phosphate enemas (SPEs) are widely used among hospitalized patients despite their potential to worsen renal failure. AIM We decided to assess the extent to which this side effect is clinically relevant. DESIGN We conducted a matched case-control, retrospective study in a cohort of hospitalized patients. METHODS Patients treated and untreated with SPEs were matched for age, gender, baseline creatinine, usage of certain medications and several background diagnoses. Three groups of matched patients (whole study cohort, patients with baseline creatinine > 1.5 mg/dl and those with baseline creatinine > 2 mg/dl) were compared with regards to their creatinine and blood electrolyte concentrations during 3 consecutive hospitalization days after SPE application. RESULTS Four hundred and twelve patients were included in this study of which 206 were treated by single SPEs. Exact matching was done for the whole study cohort, for 108 patients with baseline creatinine > 1.5 mg/dl and for 58 patients with baseline creatinine > 2 mg/dl. During 3 consecutive days after SPEs, the maximal blood concentrations of creatinine, phosphor and potassium did not differ significantly between treated patients and matched controls, in all three patients' groups. CONCLUSION Application of SPEs neither seem to worsen mild to moderate renal failure, nor are associated with hyperphosphatemia or hyperkalemia in patients hospitalized in internal medicine departments.

Abstract
RESUMO A osteocondromatose é caracterizada por nódulos únicos ou múltiplos decorrentes de um crescimento ósseo excessivo benigno. É encontrada em cães, gatos, equinos e humanos. Em felinos, tem maior incidência dos dois aos quatro anos de idade. A etiologia em gatos está relacionada ao vírus da leucemia felina, e também já foi encontrada relação com o fibrossarcoma. A manifestação clínica depende do local acometido e do tamanho da lesão. O diagnóstico definitivo é por meio de histopatologia e o prognóstico é desfavorável, pois ocorrem muitas recidivas. Este relato de caso objetiva descrever a apresentação dessa enfermidade em um felino jovem.

Abstract
BACKGROUND Dental handpieces are used in critical and semi-critical operative interventions. Although some dental professional bodies recommend that dental handpieces are sterilized between patient use there is a lack of clarity and understanding of the effectiveness of different steam sterilization processes. The internal mechanisms of dental handpieces contain narrow lumens (0.8-2.3 mm) which can impede the removal of air and ingress of saturated steam required to achieve sterilization conditions. AIM To identify the extent of sterilization failure in dental handpieces using a non-vacuum process. METHODS In-vitro and in-vivo investigations were conducted on widely used UK bench-top steam sterilizers and three different types of dental handpieces. The sterilization process was monitored inside the lumens of dental handpieces using thermometric (TM; dataloggers), chemical indicator (CI), and biological indicator (BI) methods. FINDINGS All three methods of assessing achievement of sterility within dental handpieces that had been exposed to non-vacuum sterilization conditions demonstrated a significant number of failures [CI: 8/3024 (fails/no. of tests); BI: 15/3024; TM: 56/56] compared to vacuum sterilization conditions (CI: 2/1944; BI: 0/1944; TM: 0/36). The dental handpiece most likely to fail sterilization in the non-vacuum process was the surgical handpiece. Non-vacuum sterilizers located in general dental practice had a higher rate of sterilization failure (CI: 25/1620; BI: 32/1620; TM: 56/56) with no failures in vacuum process. CONCLUSION Non-vacuum downward/gravity displacement, type N steam sterilizers are an unreliable method for sterilization of dental handpieces in general dental practice. The handpiece most likely to fail sterilization is the type most frequently used for surgical interventions.

Abstract
BACKGROUND New cases of oropharyngeal squamous cell carcinoma (OPSCC) are routinely tested for HPV. HPV in saliva can be detected with PCR, but its clinical applicability in the context of OPSCC remains unknown. METHODS Forty-six consecutive patients diagnosed with OPSCC had pre-treatment saliva specimens collected. PCR for HPV on saliva was compared to p16 IHC and HPV DNA in situ hybridisation (ISH) on surgical biopsies. RESULTS The sensitivity and specificity of saliva testing when compared to the reference test of p16 IHC and HPV DNA ISH were 72.2% and 90%, and positive and negative predictive values were 96.3% and 47.4%. There were no adverse events. Time from last meal, smoking, alcohol drinking and physical exercise did not impact on results. CONCLUSIONS Saliva testing is a promising test to detect HPV in patients with OPSCC. A positive result could avoid the need for surgical biopsies, thereby reducing costs, patient morbidity and expedite treatment.

Abstract
Thiopurine-related hematotoxicity in pediatric acute lymphoblastic leukemia (ALL) and inflammatory bowel diseases has been linked to genetically defined variability in thiopurine S-methyltransferase (TPMT) activity. While gene testing of TPMT is being clinically implemented, it is unclear if additional genetic variation influences TPMT activity with consequences for thiopurine-related toxicity. To examine this possibility, we performed a genome-wide association study (GWAS) of red blood cell TPMT activity in 844 Estonian individuals and 245 pediatric ALL cases. Additionally, we correlated genome-wide genotypes to human hepatic TPMT activity in 123 samples. Only genetic variants mapping to chromosome 6, including the TPMT gene region, were significantly associated with TPMT activity (P < 5.0 × 10-8 ) in each of the three GWAS and a joint meta-analysis of 1,212 cases (top hit P = 1.2 × 10-72 ). This finding is consistent with TPMT genotype being the primary determinant of TPMT activity, reinforcing the rationale for genetic testing of TPMT alleles in routine clinical practice to individualize mercaptopurine dosage.

Abstract
OBJECTIVES To identify the most cost-effective treatment strategy in patients with early stage (T1 and T2) cancers of the laryngeal glottis. DESIGN A Markov decision model populated using data from updated systematic reviews and meta-analyses, with attributable costs from NHS sources. Data on local control and mortality were obtained from updates of existing systematic reviews conducted for the NICE guideline on cancer of the upper aerodigestive tract. Procedure costs were sourced from NHS reference costs 2013/14 by applying tariffs associated with the appropriate health resource group code SETTING: The UK National Health Service. POPULATION Patients with early stage (T1 and T2) cancers of the laryngeal glottis. INTERVENTIONS Transoral laser microsurgery (TLM) and radiation therapy (RT). MAIN OUTCOME MEASURES Total costs, incremental costs and quality adjusted life years (QALYs) over a 10-year time horizon. RESULTS Radiation therapy as the initial treatment strategy was found to be more expensive (£2654 versus £623) and less effective (QALY reduction of 0.141 and 0.04 in T1a and T1b-T2 laryngeal cancers, respectively) than TLM. The dominance of TLM for T1a cancers was unchanged in most scenarios modelled in sensitivity analysis. For T1b-T2 laryngeal cancers, the result changed in numerous scenarios. In probabilistic sensitivity analysis, TLM was found to have a 71% and 58% probability of being cost-effective in T1a and T1b-T2 laryngeal cancers, respectively. CONCLUSIONS Transoral laser microsurgery is a cost-effective strategy to adopt in the management of T1a laryngeal cancers. Uncertainty remains over the optimal strategy to adopt in T1b-T2 laryngeal cancers.

Abstract
Background and Purpose : The aim of this study was to evaluate the efficacy, safety, and tolerability of cerebrolysin in the early recovery phase after acute ischemic stroke. Methods. This prospective, randomized, double-blinded, placebo-controlled, multicenter, parallel-group study enrolled a total of 100 patients within 18 h after the onset of stroke. The patients were treated with Cerebrolysin (30 mL over seven days followed by 10 mL until day 30) or placebo once daily over a period of four weeks. Efficacy was primarily assessed by the NIH Stroke Scale at day 30, and additional parameters included the modified Rankin Scale, the Clinical Global Impression, the Patient Global Satisfaction (PGS) and the Mini Mental State Examination (MMSE). Nonparametric statistical procedures employing the Wilcoxon-Mann-Whitney test were used for data analysis. Safety and tolerability were assessed by adverse events, vital signs, and laboratory parameters. Results.The estimated effect size on the change from baseline in the NIH Stroke Scale on day 30 indicated a medium to large superiority of cerebrolysin compared to placebo (Mann-Whitney [MW] 0.66; 95% confidence interval [CI] 0.55-0.78, P=0.005). Similar effect sizes were reported for the modified Ranking Scale (MW 0.65; 95% CI 0.54-0.76; P=0.010) and the Clinical Global Impression (MW 0.70; 95% CI 0.55-0.85; P=0.006). Effect sizes in the MMSE and PGS did not reach statistical significance. No significant group differences were seen in any of the safety parameters. Conclusions. Cerebrolysin was effective, safe, and well tolerated in the early recovery phase after acute ischemic stroke and significantly improved neurological and global function outcomes compared to placebo.

Abstract
The use of optical technologies may be beneficial when measuring breathing biomechanics. The purpose of this study was twofold: i) to enhance the optoelectronic plethysmography (OEP) algorithm performance for the volume estimation by the use of a novel volume calibration procedure and ii) to compare the OEP volumes gained by a commercial optoelectronic system against actual respiratory volumes measured by a breath-by-breath gas analyzer (BbB). The OEP volume algorithm calibration was performed by the use of a novel volume calibration procedure based on both a calibrator device that delivered known volumes changes and one ad-hoc designed software for the static and dynamic calibration analysis. OEP algorithm threshold, accuracy, repeatability and the volume algorithm calibration were investigated. Tidal volume (VT) measurements performed simultaneously by the calibrated OEP algorithm and BbB analyzer were compared. VT measured simultaneously by OEP and BbB was collected during submaximal exercise tests in five trained healthy participants in two conditions (with hunched shoulders and in normal shoulder position). The two methods were compared by linear regression and Bland-Altman analysis in both positions. The average difference between methods and the discrepancy were calculated. The OEP-BbB correlation was high in both positions, R2=0.92 and R2=0.97 for hunch and normal one, respectively. Bland-Altman analysis demonstrated that OEP algorithm systematic difference was lower than 100mL. The limits of agreement assessed in both positions are comparable. The difference between measurements suggesting that OEP may be a useful tool to analyze chest wall volume changes and breathing mechanics during intense exercise.
