The influence of the Ini-tial Severity of Coronary Artery Lesion (by the Syntax Score) on the Midterm Prognosis of Patients With Acute Myocardial Infarction Without ST Segment Elevation.

Aim      To study the effect of the baseline severity of coronary artery damage according to the SYNTAX scale (baseline score of coronary lesions, BSCL) on the mid-term prognosis in patients with non-ST segment elevation acute myocardial infarction (AMI) (NSTEMI), and to identify the threshold BSCL value that determines high and low risks of adverse cardiac outcomes.Material and methods  A retrospective analysis was performed for the hospital treatment of patients with NSTEMI (n=421) who had undergone percutaneous coronary intervention (PCI). 256 patients with a repeated hospitalization in mid-term (11.6±3.2 months) were selected for the study. These patients were followed up for the incidence of acute coronary syndrome (ACS), unscheduled repeated myocardial revascularization (URR), and of the composite endpoint (CEP) that included at least one the following events: death, recurrent AMI, unstable angina (UA), and URR. The effect of BSCL on the incidence of these events in mid-term was proven (р<0.05), and then the BSCL threshold value was determined, which allowed segregation of patients into groups of high and low risk of adverse cardiac outcomes.Results The threshold BSCL value for the risk of ACS was determined as score 14 (odds ratio, OR, 2.79; 95 % confidence interval, CI: 1.32-5.89); for URR and CEP, score 13 (OR, 2.21; 95 % CI: 1.22-4.01 and OR, 2.38; 95 % CI: 1.32-4.31, respectively). Since these threshold values were comparable, for the composite category of events (CEP), the BSCL threshold comprised score 13, and namely this value was taken as a base. According to the multifactorial Cox regression at BSCL score ≥13, the probability of earlier CEP in mid-term was 2.44 times higher than at lower BSCL values (OR, 2.44; 95 % CI: 1.41-4.21; р=0.001). Furthermore, according to the Kaplan-Meier estimate, the effect of BSCL on the survival without adverse cardiac outcomes becomes significant starting from the second half-year (р=0.001, log-rank test).Conclusion      In NSTEMI patients, the SYNTAX baseline score of coronary lesions >13 is an independent predictor of adverse cardiac outcomes in mid-term starting from the second half-year. Thus, patients with BSCL ≥13 should undergo a follow-up examination no later than at 6 months independent on their clinical condition..

Delivery of HIV test results, post-test discussion and referral in health care settings: a review of guidance for European countries.

OBJECTIVES: HIV testing and counselling (HTC) guidelines support and promote best practice among service providers. Few European countries have national HTC guidelines and most rely on guidance from regional and international bodies. This study examines recommendations in current pan-European and global guidelines regarding test result delivery, post-test discussion and referral pathways in health care settings, and reviews the types of evidence upon which recommendations are based. METHODS: A systematic review and comparative content analysis of relevant guidelines identified through a literature search and review of targeted organization websites were carried out. RESULTS: One global and three pan-European guidelines were reviewed. There was general consensus that any test result should be confidential and delivered privately to a patient; positive results should be delivered in person by a health care professional; negative test results could also be delivered by telephone, text message or post. Analyses show conflicting guidance relating to the provision of post-test counselling, and inconsistencies in referral pathways to specialist treatment for positive test results. There is limited reference to published evidence in support of recommendations. Instead there is heavy reliance on expert opinion/consultation and other previous/existing guidelines when developing guidelines. Scientific evidence, where stated, is often more than ten years old, and based predominantly on US/UK research. CONCLUSIONS: While largely in agreement, current pan-European and global HTC guidelines have inconsistencies, particularly regarding post-test counselling and referral pathways to specialized services. Our findings highlight the need for an up-to-date review of more current evidence from wider European settings to support the process of expert consultation.

HIV testing uptake among female sex workers and men who have sex with men in Tbilisi, Georgia.

OBJECTIVES: The aim of the study was to investigate HIV testing practice among female sex workers (FSWs) and men who have sex with men (MSM) in Tbilisi, Georgia and to identify determinants of never testing behaviour among MSM. METHODS: Data obtained in two rounds of bio-behavioural surveys among FSWs (2006 and 2009) and MSM (2007 and 2010) were analysed. Determinants of never testing behaviour among MSM were investigated among 278 respondents recruited in 2010 through respondent-driven sampling. RESULTS: Knowledge about the availability of HIV testing and never testing behaviour did not show changes among FSWs and MSM. Every third FSW and every second MSM had never been tested for HIV according to the latest surveys in 2010. In bivariate analysis among MSM, consistent condom use during anal intercourse with a male partner in the last year, awareness of HIV testing locations and preventive programme coverage were negatively associated with never testing behaviour, while those who considered themselves at no risk of HIV transmission were more likely to have never been tested. In multivariate analysis, lower odds of never testing for HIV remained for those who were aware of HIV testing locations [adjusted odds ratio (AOR) 0.12; 95% confidence interval (CI) 0.04-0.32] and who reported being covered by HIV prevention programmes (AOR 0.26; 95% CI 0.12-0.56). CONCLUSIONS: In view of the concentrated HIV epidemic among MSM in Georgia and the low rate of HIV testing uptake, interventions in this key population should take into consideration the factors associated with testing behaviour. The barriers to HIV testing and counselling uptake should be further investigated.
