Unnecessary antibiotic use in men who have sex with men (MSM) with anogenital symptoms attending a sexual health clinic: a retrospective analysis.

OBJECTIVES: To quantify the amount of unnecessary antibiotics, in particular ceftriaxone, given to men who have sex with men (MSM) with anogenital symptoms as part of presumptive management in an urban sexual health clinic and examine factors associated with unnecessary ceftriaxone. METHODS: This is a retrospective cross-sectional analysis of electronic records from all visits involving MSM reporting symptoms of bacterial sexually transmitted infection (STI) and who received presumptive antibiotics at Sydney Sexual Health Centre. The following variables were extracted: demographic and sexual behaviour data, presenting symptoms, prior STI diagnoses, use of anoscopy, use of point-of-care microscopy, prescriptions of antibiotics and subsequent nucleic acid amplification testing (NAAT) results for chlamydia and gonorrhoea in all anatomical sites (urethra, pharynx and rectum). We defined unnecessary antibiotic as an agent prescribed to treat an STI organism that was subsequently not detected. RESULTS: Among 1061 visits in this analysis, 41.8% yielded negative NAAT results for both chlamydia and gonorrhoea in all anatomical sites. There were 44.3% of visits which had positive gonorrhoea NAAT result in at least one anatomical site. There were 187 courses of ceftriaxone prescribed in patients who tested negative for gonorrhoea in all anatomical sites and therefore were unnecessary. Unnecessary ceftriaxone prescribing occurred in 50.2% of visits with anorectal symptoms, 19.6% of scrotal symptoms and 7.3% of urethral symptoms. Microscopy was associated with significantly less unnecessary ceftriaxone in urethral but not anorectal or scrotal presentations. In multivariable analysis, the following factors were associated with a higher likelihood of unnecessary ceftriaxone use: anorectal symptoms, scrotal symptoms, gonorrhoea in the preceding year, contact of a bacterial STI and living with HIV. CONCLUSIONS: This study highlights the significant amount of unnecessary ceftriaxone used for STI symptoms in MSM. A new pathway incorporating rapid point-of-care molecular testing in symptomatic patients may improve the precision of antibiotic prescribing and reduce unnecessary use.

Nailbed HPV-related Bowen's disease in a man living with HIV.

Human papillomavirus (HPV) is a common sexually transmitted infection with wide-ranging clinical manifestations. High-risk anogenital HPV genotypes have also been reported to cause extragenital disease. We describe the case of a 69-year-old male patient living with HIV who was diagnosed with HPV-16 associated Bowen's Disease (BD) of the right middle finger nailbed, despite good virologic control and immune reconstitution. The lesion was managed surgically with adjunctive post-exposure HPV vaccination. This case adds to the growing body of evidence of extra-genital HPV disease attributable to anogenital genotypes in people living with HIV.

Investigating the Impact of COVID-19 Infection on Dry Eye Parameters.

PURPOSE: This study aims to compare dry eye parameters before and after COVID-19 infection in dry eye patients. METHODS: We included 44 dry eye patients (88 eyes) from our existing dry eye cohort, with 22 belonging to the post-COVID-19 group due to a prior COVID-19 infection and the other 22 forming the non-COVID-19 group as they had no history of COVID-19. We examined and compared the dry eye parameters of the post-COVID-19 group, including the ocular surface disease index (OSDI), Schirmer's test results (ST), non-invasive Keratography tear break-up time (NIKBUT), lipid layer thickness (LLT), Meibomian gland dysfunction (MGD), and the grading of papillae and follicles, both before and after the COVID-19 infection. We also compared the dry eye parameters difference of the post-COVID-19 group with the non-COVID-19 group. RESULTS: The post-COVID-19 group was comprised of individuals with an average age of 38.36 ± 14.99 years, of which 82% were female. The time interval between the two tests was 16.92 ± 5.40 months, which did not differ significantly from the non-COVID-19 group. Compared to the pre-COVID-19 eyes, the post-COVID-19 eyes showed a significant decrease in the average LLT (52.86 ± 18.00 nm vs. 63.00 ± 22.40 nm, p < 0.001), as well as the maximum LLT (67.89 ± 20.81 nm vs. 78.48 ± 20.55 nm, p < 0.001). The MGD in both the upper (1.75 ± 0.84) and lower eyelids (1.43 ± 0.73) worsened after a COVID-19 infection. Additionally, the grading of papillae was worse following a COVID-19 infection (0.61 ± 0.69 vs. 0.16 ± 0.37, p < 0.001). The multivariate linear regression model revealed a negative association between COVID-19 infection and NIKBUT-average (ß = -2.98, 95%CI: (-5.82, -0.15), p = 0.039), LLT-average (ß = -14.12, 95%CI: (-22.66, -5.59), p = 0.001), and LLT max (ß = -15.65, 95%CI: (-23.09, -8.20), p < 0.001). CONCLUSION: From preliminary results, we concluded that dry eye patients who have been infected with COVID-19 appear to have a more severe dry eye condition, as evidenced by lower LLT, worse papillae and MGD, and shorter NIKBUT. It is important to raise awareness of this potential long-term symptom of COVID-19, especially among existing dry eye patients.

Interim position statement on doxycycline post-exposure prophylaxis (Doxy-PEP) for the prevention of bacterial sexually transmissible infections in Australia and Aotearoa New Zealand - the Australasian Society for HIV, Viral Hepatitis and Sexual Health Medicine (ASHM).

Recent studies have provided evidence for the effectiveness of using doxycycline (Doxy-PEP) to prevent bacterial sexually transmissible infections (STI), namely chlamydia, gonorrhoea, and syphilis, among gay, bisexual, and other men who have sex with men who have experienced multiple STIs. However, there remain several unanswered questions around potential adverse outcomes from Doxy-PEP, including the possibility of inducing antimicrobial resistance in STIs and other organisms, and the possibility of disrupting the microbiome of people who choose to use Doxy-PEP. This interim position statement from the Australasian Society for HIV, Viral Hepatitis and Sexual Health Medicine aims to outline the current evidence for Doxy-PEP, and to highlight potential adverse outcomes, to enable clinicians to conduct evidence-based conversations with patients in Australia and Aotearoa New Zealand who intend to use Doxy-PEP.

The Rise in Cardiovascular Risk Factors and Chronic Diseases in Guyana: A Narrative Review.

Background: Guyana experiences health challenges related to both communicable and non-communicable diseases. Cardiovascular disease (CVD) is the most common non-communicable disease in Guyana. The main causes of the increased prevalence of non-communicable diseases are modifiable risk factors (e.g. obesity, hypertension, elevated cholesterol, unhealthy dietary patterns) and non-modifiable risk factors (e.g. age and genetics). Objective: The aim of this review is to understand CVD and risk factor data, in the context of ethnicity in Guyana. Methods: A review of the published literature as well as government and international health agency reports was conducted. All publications from 2002-2018 describing CVD and related risk factors in Guyana were screened and extracted. Findings: The population of Guyana is comprised of six ethnic groups, of which East Indian (39.8%) and African (29.3%) are the majority. CVD accounts for 526 deaths per 100,000 individuals per year. Among Indo-Guyanese and Afro-Guyanese, CVD is the primary cause of death affecting 32.6% and 22.7% of the populations, respectively. Within the Indo-Guyanese and Afro-Guyanese communities there is a high prevalence of hypertension and diabetes among individuals over the age of 50. There is a lack of available data describing ethnic disparities in CVD and related risk factors such as obesity, smoking, alcohol, physical activity and diet in Guyana. Conclusions: Important knowledge gaps remain in understanding the ethnic disparities of CVD and related risk factors in Guyana. Future research should focus on high risk populations and implement widespread screening and treatment strategies of common risk factors such as hypertension, diabetes, and elevated cholesterol to curb the epidemic of CVD in Guyana.

The nasocardiac reflex during nasoendoscopy: A commonly overlooked risk.

PURPOSE: The nasocardiac reflex is known but not well researched. We aimed to ascertain the electrocardiographic features of the reflex and to chronologically map the heart rhythm dynamics during nasoendoscopy. We also intended to identify variables that could potentially affect the occurrence of this reflex. MATERIAL AND METHODS: A prospective, quasi-experimental physiological study. Selected healthy subjects were observed electrocardiographically for 60 s continuously in three equal phases of 20 s each - baseline phase, nasoendoscopic phase, and recovery phase (post-nasoendoscopy). Heart rate fluctuations were charted, followed by identification of a positive nasocardiac reflex group of subjects and a negative group. Analyses against multiple variables were done. RESULTS: A total of 53 subjects were analysed. Heart rate during the baseline phase was 81.0 ± 9.9, nasoendoscopic phase was 72.7 ± 10.1, and recovery phase was 75.2 ± 9.6. Sixteen subjects (30.2%) had a positive nasocardiac reflex, and they remained in sinus rhythm with no occurrences of skipped beats, atrioventricular blocks or asystoles. One subject (1.9%) developed temporary ectopic premature ventricular contractions after nasoendoscopy. No variables were found affecting the incidence of a nasocardiac reflex in our study. CONCLUSIONS: The pattern of heart rate dynamics was consistent as heart rates drop rapidly upon endoscope insertion and recover in some measure after its withdrawal. Although all our subjects remained asymptomatic, clinicians should not overlook the risks of a severe nasocardiac reflex when performing nasoendoscopy. We recommend that electrical cardiac monitoring be part of the management of vasovagal responses during in-office endonasal procedures.

Effect of age on the association between recreational drug use and sexual risk behaviour: a cross-sectional observational analysis.

Recreational drug use (RDU) among gay and bisexual men (GBM) is associated with higher-risk sexual behaviours, however this has not been well defined among older GBM. We investigated the association between RDU and sexual behaviours among older GBM in Sydney, Australia. 617 GBM aged 35-79 years self-reported their RDU in the past 6 months and sexual behaviours. Age-stratified univariable associations between RDU and behaviour were examined. GBM aged 35-44 years were the most likely to report RDU, with rates decreasing with increasing age (Ptrend < 0.001). Associations between RDU and higher-risk sexual behaviours were most consistently found among GBM aged 35-54 years.

Breaking silence: a survey of barriers to goals of care discussions from the perspective of oncology practitioners.

BACKGROUND: Cancer is the leading cause of death in the developed world, and yet healthcare practitioners infrequently discuss goals of care (GoC) with hospitalized cancer patients. We sought to identify barriers to GoC discussions from the perspectives of staff oncologists, oncology residents, and oncology nurses. METHODS: This was a single center survey of staff oncologists, oncology residents, and inpatient oncology nurses. Barriers to GoC discussions were assessed on a 7-point Likert scale (1 = extremely unimportant; 7 = extremely important). RESULTS: Between July 2013 and May 2014, of 185 eligible oncology clinicians, 30 staff oncologists, 10 oncology residents, and 28 oncology nurses returned surveys (response rate of 37%). The most important barriers to GoC discussions were patient and family factors. They included family members' difficulty accepting poor prognoses (mean score 5.9, 95% CI [5.7, 6.2]), lack of family agreement in the goals of care (mean score 5.8, 95% CI [5.5, 6.1]), difficulty understanding the limitations of life-sustaining treatments (mean score 5.8, 95% CI [5.6, 6.1]), lack of patients' capacity to make goals of care decisions (mean score 5.7, 95% CI [5.5, 6.0]), and language barriers (mean score 5.7, 95% CI [5.4, 5.9]). Participants viewed system factors and healthcare provider factors as less important barriers. CONCLUSIONS: Oncology practitioners perceive patient and family factors as the most limiting barriers to GoC discussions. Our findings underscore the need for oncology clinicians to be equipped with strong communication skills to help patients and families navigate GoC discussions.

Role of allied health care professionals in goals-of-care discussions with hospitalized patients and perceived barriers: a cross-sectional survey.

BACKGROUND: Allied health care professionals can contribute meaningfully to goals-of-care discussions with seriously ill hospitalized patients and their families. We sought to explore the perspective of hospital-based allied health care professionals on their role in goals-of-care discussions and to identify barriers to their participation. METHODS: We surveyed allied health care professionals (social workers, physiotherapists, occupational therapists, registered dietitians, speech-language pathologists and pharmacists) on internal medicine, hematology-oncology, medical oncology and radiation oncology wards at 2 tertiary care hospitals in Hamilton, Ontario, from April 2013 to May 2014. We modified a validated questionnaire originally designed to assess barriers to discussing goals of care from the perspective of nurses, residents and staff physicians on hospital medical wards. Respondents rated the questionnaire items on a 7-point Likert scale. RESULTS: Of the 47 allied health care professionals invited, 32 (68%) participated: 9 physiotherapists, 7 social workers, 6 occupational therapists, 4 registered dietitians, 3 pharmacists and 2 speech-language pathologists; in 1 case, the profession was unknown. The greatest perceived barriers to engaging in goals-of-care discussions were lack of patient decision-making capacity (mean rating 5.9 [standard error (SE) 0.3]), lack of awareness of patients' previous discussions with other team members (mean rating 5.7 [SE 0.3]) and family members' difficulty accepting a poor prognosis (mean rating 5.6 [SE 0.2]). Although the respondents felt it was most acceptable for staff physicians, residents and advanced practice nurses to exchange information and reach a final decision during goals-of-care discussions, they felt it was acceptable for a broader range of allied health care professionals to initiate discussions (mean rating 4.7-5.8) and to act as decision coaches (clarifying values, weighing options) with patients and families (mean rating 5.3-6.1). INTERPRETATION: Allied health care professionals are willing to initiate goals-of-care discussions and to act as a decision coach with seriously ill hospitalized patients and their families. By improving interprofessional collaboration, we can engage the entire health care team in this process.

Development of a polyclonal anti-dugong immunoglobulin G (IgG) antibody with evaluation of total plasma IgG in a living dugong (Dugong dugon) population.

Species-specific antibodies (Ab) for the measurement of immunoglobulins (Ig) are valuable tools for determining the humoral immune status of threatened and endangered wildlife species such as dugongs. However, no studies have reported antibody reagents against dugong immunoglobulin. The object of this study was to develop an Ab with specificity for dugong IgG and apply this tool to survey total IgG levels in plasma samples from a live wild population of dugongs in southern Queensland, Australia. Dugong IgG was isolated from plasma by protein A/G column chromatography and a polyclonal antiserum was successfully raised against the dugong IgG through immunization of mice. The anti-dugong antiserum was reactive with dugong serum but not immunoglobulin from other species such as rats and humans. When tested against a panel of dugong plasma samples, relative IgG levels from dugongs (n = 116) showed biologically relevant relationships with pregnancy status and a principal component of Body Mass Index (BMI)/globulin/fecal glucocorticosteroid (chronic stress) levels combined, which together accounted for 9.2% of the variation in total Ig levels. Together these data suggest that dugongs show variation in total IgG and that this correlates with some physiological parameters of dugong health.

Hematology of dugongs (Dugong dugon) in southern Queensland.

BACKGROUND: Little is known of the hematology of the dugong (Dugong dugon), a secretive and endangered coastal marine mammal. OBJECTIVES: This paper reports hematologic reference intervals (RI) for dugongs and characterizes morphologic, cytochemical, and ultrastructural features of dugong leukocytes. METHODS: Blood was collected from live, apparently healthy dugongs and analyzed using Cell-Dyn 3700 or Sysmex XT-2000iV hematology analyzers. Blood films were subjected to a series of cytochemical stains, and leukocyte structure was examined using transmission electron microscopy. RESULTS: Reference intervals were established for 14 hematologic variables, total solids, and fibrinogen for 92 dugongs. Significant differences in some variables were found for animal size class, sex, and pregnancy status, and between analyzers. Subadults had higher leukocyte and lymphocyte counts than adults. Males had higher total solids and fibrinogen than females. Pregnant females had higher HCT, MCV, and circulating nucleated RBC, and lower platelet counts than nonpregnant females. Lymphocytes were usually the predominant circulating leukocyte. Heterophil cytoplasmic granules were abundant, fine, round to ovoid, and intensely eosinophilic, and round to ovoid or rod-shaped, and variably electron dense in electron microscopy. Eosinophils contained larger round eosinophilic to orange cytoplasmic granules, which ultrastructurally were bicompartmental with a round eccentric electron-dense core. Cytochemical staining of dugong heterophils suggests biochemical similarity to those of manatees and elephants, and for eosinophils, similarity to those of elephants, ruminants, and equids. CONCLUSIONS: Generation of hematologic RI and characterization of leukocyte morphology improves evaluation of dugong health across this population and serves as a reference for other populations outside southern Queensland.

Dexamethasone Perioperative Coanalgesia in Lumbar Spine Fusion: A Controlled Cohort Study of Efficacy and Safety.

PURPOSE: A 48-hour trial of dexamethasone coanalgesia became our standard practice in May 2008. This is our research Ethics Board-approved review of this experience to date with attention to perioperative narcotics use and pain scores for the first 48 hours after surgery as well as length of stay (LOS), wound healing complications, and infections in the first 6 months, compared with the historical precedent control cohort. METHODS: Surgical case logs identified cases of 1- and 2-level elective lumbar decompression and fusion surgery performed since protocol initiation (cases) and for a like period beforehand (controls). Minimum of 6 months follow-up (sufficient to identify acute and subacute wound healing problems and perioperative infections) information was required. Hospital, Pain Service, and office records were reviewed for the extraction of outcomes data. RESULTS: We identified 132 cases and 146 controls. In 41 additional cases records were deficient. Baseline characteristics were equivalent. Cases included 70 males (53%) and 62 females (47%) of mean age 54 years (range, 18-84 y). Seventy-five (57%) cases were narcotics dependant (mean of 79.5 mg-morphine-equivalent daily). Controls included 78 males (53%) and 68 females (47%) of mean age 55 years (range, 27-85 y). Eighty-nine (61%) controls were narcotics dependant (mean 101.2 mg-morphine-equivalents daily). Mean morphine-equivalents narcotic consumption for 48 hours after surgery was 262.9 mg in cases and 280.7 mg in controls. VAS pain scores at 48 hours after surgery averaged 4.4 and 6.9 during rest and activity in the cases, and 3.7 and 6.3 during rest and activity in the controls. LOS averaged 3.9 days in cases and 5.2 days in controls. Delayed wound healing and surgical site infections were not observed in either group. CONCLUSIONS: Systemic dexamethasone after 1- and 2-level lumbar fusion surgery demonstrated minimal impact on 48 hours perioperative narcotics use with no detriment to pain control, wound healing, or infections. LOS was shortened by 25%.

The Influence of Hepatitis C Virus Genetic Region on Phylogenetic Clustering Analysis.

Sequencing is important for understanding the molecular epidemiology and viral evolution of hepatitis C virus (HCV) infection. To date, there is little standardisation among sequencing protocols, in-part due to the high genetic diversity that is observed within HCV. This study aimed to develop a novel, practical sequencing protocol that covered both conserved and variable regions of the viral genome and assess the influence of each subregion, sequence concatenation and unrelated reference sequences on phylogenetic clustering analysis. The Core to the hypervariable region 1 (HVR1) of envelope-2 (E2) and non-structural-5B (NS5B) regions of the HCV genome were amplified and sequenced from participants from the Australian Trial in Acute Hepatitis C (ATAHC), a prospective study of the natural history and treatment of recent HCV infection. Phylogenetic trees were constructed using a general time-reversible substitution model and sensitivity analyses were completed for every subregion. Pairwise distance, genetic distance and bootstrap support were computed to assess the impact of HCV region on clustering results as measured by the identification and percentage of participants falling within all clusters, cluster size, average patristic distance, and bootstrap value. The Robinson-Foulds metrics was also used to compare phylogenetic trees among the different HCV regions. Our results demonstrated that the genomic region of HCV analysed influenced phylogenetic tree topology and clustering results. The HCV Core region alone was not suitable for clustering analysis; NS5B concatenation, the inclusion of reference sequences and removal of HVR1 all influenced clustering outcome. The Core-E2 region, which represented the highest genetic diversity and longest sequence length in this study, provides an ideal method for clustering analysis to address a range of molecular epidemiological questions.

Serum biochemistry reference intervals of live wild dugongs (Dugong dugon) from urban coastal Australia.

BACKGROUND: Little is known about the baseline clinical pathology of the dugong (Dugong dugon), a vulnerable marine mammal found in tropical coastal marine systems. OBJECTIVES: The purpose of the study was to collect and determine reference intervals (RI) for select serum biochemical variables for dugongs, and to analyze differences between males and females and different age groups. METHODS: Reference intervals were established from 103 apparently healthy, wild-caught dugongs for 31 analytes using a Beckman Coulter AU400 Automated Chemistry Analyzer and an Olympus AU680 Chemistry-Immuno Analyzer. RESULTS: Significant differences (P < .05) in some of the variables were found related to size class, sex, and pregnancy status. Adult dugongs had higher serum sodium, potassium, bicarbonate, glucose, and l-lactate concentrations and higher anion gap, compared to sub-adults. Male dugongs had higher triglyceride and l-lactate concentrations than females. Pregnant females displayed higher l-lactate levels compared to nonpregnant animals. Statistical differences in variables within the population contributed to better understanding of the physiologic differences between cohorts. Some serum biochemistry changes observed in this study here also potentially include some effects of pursuit on dugongs (eg, higher l-lactate); however, as all dugongs were subject to similar capture and handling, serum biochemistry RI should be considered as normal for captured dugongs. CONCLUSIONS: The serum biochemical RI documented here are considered representative of a population of healthy captured dugongs. They provide a baseline for health surveillance of this and other dugong populations.

The impacts of observing flawed and flawless demonstrations on clinical skill learning.

OBJECTIVES: Clinical skills expertise can be advanced through accessible and cost-effective video-based observational practice activities. Previous findings suggest that the observation of performances of skills that include flaws can be beneficial to trainees. Observing the scope of variability within a skilled movement allows learners to develop strategies to manage the potential for and consequences associated with errors. This study tests this observational learning approach on the development of the skills of central line insertion (CLI). METHODS: Medical trainees with no CLI experience (n = 39) were randomised to three observational practice groups: a group which viewed and assessed videos of an expert performing a CLI without any errors (F); a group which viewed and assessed videos that contained a mix of flawless and errorful performances (E), and a group which viewed the same videos as the E group but were also given information concerning the correctness of their assessments (FA). All participants interacted with their observational videos each day for 4 days. Following this period, participants returned to the laboratory and performed a simulation-based insertion, which was assessed using a standard checklist and a global rating scale for the skill. These ratings served as the dependent measures for analysis. RESULTS: The checklist analysis revealed no differences between observational learning groups (grand mean ± standard error: [20.3 ± 0.7]/25). However, the global rating analysis revealed a main effect of group (d.f.2,36 = 4.51, p = 0.018), which describes better CLI performance in the FA group, compared with the F and E groups. CONCLUSIONS: Observational practice that includes errors improves the global performance aspects of clinical skill learning as long as learners are given confirmation that what they are observing is errorful. These findings provide a refined perspective on the optimal organisation of skill education programmes that combine physical and observational practice activities.

Left ventricular myocardial dysfunction and premature atherosclerosis in patients with axial spondyloarthritis.

OBJECTIVE: To evaluate left ventricular (LV) function and carotid intima-media thickness (IMT) in patients with axial SpA in relationship to underlying disease severity. METHODS: We recruited 104 patients with axial SpA and 50 controls. Detailed transthoracic echocardiography was performed and analysed with two-dimensional speckle tracking strain analysis for systolic function and tissue Doppler-derived E/E' for diastolic function assessment. Carotid IMT was measured by ultrasonography to evaluate subclinical atherosclerosis. Radiological severity of patients with axial SpA was assessed by the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS). RESULTS: Despite a similar LV ejection fraction [62.7% (s.d. 3.9) vs 62.8% (s.d. 3.8), P = 0.83], patients with axial SpA had impaired LV myocardial longitudinal strain (LS), circumferential strain (CS) and radial strain (RS) compared with controls [-18.1% (s.d. 2.4) vs -20.1% (s.d. 2.5), -17.2% (s.d. 2.2) vs -20.3% (s.d. 2.9) and 37.1% (s.d. 8.6) vs 43.2% (s.d. 10.9), respectively; all P < 0.01]. In addition, patients with axial SpA had a greater E/E' [7.9 (s.d. 2.5) vs 7.0 (s.d. 1.7), P < 0.01] and carotid IMT [0.78 mm (s.d. 0.19) vs 0.69 mm (s.d. 0.10), P < 0.01] than controls. After adjusting for potential confounding factors, axial SpA remained independently associated with LV myocardial strains, E/E' and carotid IMT. Importantly, multivariate linear regression analysis demonstrated that mSASSS was independently associated with LV longitudinal strain, E/E' and carotid IMT. CONCLUSION: Our study demonstrated that patients with axial SpA had impaired LV systolic and diastolic function and increased carotid IMT. Importantly, mSASSS was independently associated with LV longitudinal strain, E/E' and carotid IMT after adjusting for confounding factors. Speckle tracking echocardiography may be a useful tool for early detection of impaired LV function in patients with SpA and carotid IMT examination can provide valuable assessment of subclinical atherosclerosis in patients with SpA.
