RESUMO

AIM: We aimed to systematically compare literature on prevalence of modifiable and non-modifiable risk factors for early compared to late-onset coronary heart disease (CHD). METHODS: PubMed, CINAHL, Embase, and Web of Science databases were searched (review protocol registered in PROSPERO CRD42020173216). Study quality was assessed using the National Heart, Lung and Blood Institute tool for observational and case-control studies. Review Manager 5.3 was used for meta-analysis. Effect sizes were expressed as odds ratio (OR) and mean differences (MD)/standardised MD (SMD) with 95% confidence intervals (CI) for categorical and continuous variables. RESULTS: Individuals presenting with early-onset CHD (age <65 years) compared to late-onset CHD had higher mean body mass index (MD 1.07 kg/m2; 95% CI 0.31-1.83), total cholesterol (SMD 0.43; 95% CI 0.23-0.62), low-density lipoprotein (SMD 0.26; 95% CI 0.15-0.36) and triglycerides (SMD 0.50; 95% CI 0.22-0.68) with lower high-density lipoprotein-cholesterol (SMD 0.26; 95% CI -0.42--0.11). They were more likely to be smokers (OR 1.76, 95% CI 1.39-2.22) and have a positive family history of CHD (OR 2.08, 95% CI 1.74-2.48). They had lower mean systolic blood pressure (MD 4.07 mmHg; 95% CI -7.36--0.78) and were less likely to have hypertension (OR 0.47, 95% CI 0.39-0.57), diabetes mellitus (OR 0.56, 95% CI 0.51-0.61) or stroke (OR 0.31, 95% CI 0.24-0.42). CONCLUSION: A focus on weight management and smoking cessation and aggressive management of dyslipidaemia in young adults may reduce the risk of early-onset CHD.

RESUMO

BACKGROUND: Prior studies have reported a high rate of unplanned readmissions following acute percutaneous coronary intervention (PCI). Data outside the USA comparing 30-day unplanned readmissions following elective PCI to those who undergo acute PCI remain limited. METHODS: Patients who underwent a PCI procedure in Australia and New Zealand between 2010 and 2015 were included. We determined the rates, causes and predictors of 30-day unplanned readmissions, as well as rates of repeat revascularisation procedures, for patients who underwent an elective or acute PCI. Predictors of readmissions were identified using logistic regression. RESULTS: A total of 199,686 PCI encounters were included, of which 74,890 (37.5%) were elective and 124,796 (62.5%) were acute procedures. Overall, 10.6% of patients had at least one unplanned readmission within 30 days of discharge with lower rates following elective PCI (7.0%) compared to acute PCI (12.7%) (p<0.01). Non-specific chest pain was the commonest cause of readmission after elective and acute PCI, accounting for 20.7% and 21.5% of readmission diagnoses, respectively. Readmissions for acute myocardial infarction (13.0% vs 4.6%, p<0.01) and heart failure (6.5% vs 3.3%, p<0.01) were higher following acute PCI compared to elective PCI. Among readmitted patients, 16.7% had a coronary catheterisation, 12.2% had a PCI and 0.7% had coronary artery bypass surgery. Multivariable predictors of 30-day unplanned readmission included female sex and comorbidities such as heart failure, metastatic disease, chronic lung disease and renal failure (p<0.0001 for all). CONCLUSIONS: Unplanned readmissions following elective or acute PCI are high. Clinical and quality-control measures are required to prevent avoidable readmissions in both settings.

RESUMO

INTRODUCTION: The incidence of oropharyngeal squamous cell carcinoma (OPSCC) is increasing globally, reflecting an increase in human papillomavirus (HPV)-related lesions. Indigenous populations are disproportionately affected by OPSCCs. Currently, testing for oral HPV is not recommended as a screening tool to permit early detection of OPSCCs due to the high population prevalence of HPV infection. Periodontitis may be a marker of oral HPV infection, but previous research evaluating this association has been inconclusive. Here we report a large population-based study examining the association between high-risk oral HPV infection and periodontitis among Indigenous South Australians. METHODS: We utilised a large convenience sample of Indigenous South Australians aged 18+ years recruited between February 2018 and February 2020. Of the original cohort (n = 1011), 748 (73.9%) participants participated in the 12 month follow-up. Detailed information on sociodemographic characteristics, health-related behaviours, and sexual history were collected at enrolment. Saliva samples were collected at 12 months and tested for the presence of oral HPV DNA using the optimized general primer (GP) + PCR system. The primary outcomes were the prevalence of any high-risk oral HPV DNA, and separately, HPV 16 and/or 18. Periodontitis was assessed at follow-up by using validated self-reported periodontitis screening questions. Logistic regression analyses were undertaken to assess the association between self-reported periodontitis and oral HPV infection with adjustment for potential sociodemographic and behavioural confounders, with estimates presented as odds ratios (OR) and 95% confidence interval (CI). RESULTS: Data on 673 participants (89.9% of the follow-up cohort) were available. Participants ranged in age from 18 to 80 (mean age 42.2, SD 14.7) and 31.5% were male. Overall, 115 (17.1%) participants had self-reported periodontitis, 40 (5.9%) had any high-risk oral HPV and 14 (2.1%) had HPV 16 and/or 18. Any high-risk HPV was detected among seven (17.5%) participants and HPV 16 and/or 18 was detected in three (21.4%) who self-reported periodontitis. In the regression analyses no significant association was found between self-reported periodontitis and high-risk oral HPV (adjusted OR: 1.10; 95% CI: 0.45-2.70) or HPV 16 and/or 18 (adjusted OR: 1.27; 95% CI: 0.32-5.03). CONCLUSION: This study did not find any association between self-reported periodontitis and high-risk oral HPV among Indigenous South Australians. Further targeted studies with standardized clinical measures of periodontal disease are needed to clarify the link between high-risk oral HPV and periodontal disease. If confirmed this would add further weight to the importance of recommendations about the utility of periodontitis screening to identify individuals at risk of carrying high-risk oral HPV, who may benefit from more intensive screening and ongoing monitoring.

RESUMO

BACKGROUND: Previous research has suggested an ethnic association of Heck's disease with a prominent genetic and familial inheritance pattern, but no systematic review has been reported, which has collected all the evidence in one paper. The aim was estimation of the updated age estimates and gender predilection of this disease and also questioning its proposed link to ethnic and geographical factors. METHODS: Heck's disease from 1966 until present are tabulated, including various descriptive characteristics. After removal of duplicates and adhering to all the inclusion criteria, we shortlisted 95 case reports. The quality assessment of all included studies has been done following STROBE (STrengthening the Reporting of OBservational studies in Epidemiology) guidelines. RESULTS: We found an age range of 3-92 years (mean: 23.1 years) with a male to female ratio of 3:4. Geographical distribution revealed one of the main findings of this study, which was an increased incidence of Heck's disease in the European region. CONCLUSIONS: As already observed and established, there is a much greater prevalence of this disease in the indigenous populations of the world and more research should be encouraged to understand the correct transmission and pattern of spread of this disease.

RESUMO

BACKGROUND: Little is known about the utilisation and safety of catheter ablation of atrial fibrillation (AF) among public and private sector hospitals. AIMS: To examine the uptake of AF ablations and compare procedural safety between the sectors. METHOD: Hospitalisation data from all public and private hospitals in four large Australian states (NSW, QLD, VIC and WA) were used to identify patients undergoing AF ablation from 2012 to 17. The primary endpoint was any procedure-related complications up to 30-days post-discharge. Logistic regression was used to evaluate the association between treatment at a public hospital and risk of complications adjusting for covariates. RESULTS: Private hospitals performed most of the 21,654 AF ablations identified (n = 16,992, 78.5 %), on patients who were older (63.5 vs. 59.9y) but had lower rates of heart failure (7.9 % vs. 10.4 %), diabetes (10.2 % vs. 14.1 %), and chronic kidney diseases (2.4 % vs. 5.2 %) (all p < 0.001) than those treated in public hospitals. When compared with private hospitals, public hospitals had a higher crude rate of complications (7.25 % vs. 4.70 %, p < 0.001). This difference remained significant after adjustment (OR 1.74 [95 % CI 1.54-2.04]) and it occurred with both in-hospital (OR 1.83 [1.57-2.14]) and post-discharge (OR 1.39 [1.06-1.83]) complications, with certain complications including acute kidney injury (OR 5.31 [3.02-9.36]), cardiac surgery (OR 5.18 [2.19-12.27]), and pericardial effusion (OR 2.18 [1.50-3.16]). CONCLUSIONS: Private hospitals performed most of AF ablations in Australia with a lower rate of complications when compared with public hospitals. Further investigations are needed to identify the precise mechanisms of this observed difference.

RESUMO

BACKGROUND: Non-osteoporotic patients with endocrine-sensitive breast cancer are often treated with denosumab only during the anti-aromatase treatment, and when the anti-aromatase therapy is discontinued, no antiresorptive drug is prescribed. This case report clearly shows how even a patient with a low risk of fractures could have multiple rebound vertebral fractures after denosumab discontinuation. CASE PRESENTATION: We report the case of a 60-year-old woman who suffered from multiple vertebral fractures only seven months after discontinuation of denosumab that had been administered to prevent bone loss related to three years of aromatase inhibitors as adjuvant therapy for breast cancer. No antiresorptive therapy was prescribed at the time of denosumab discontinuation, assuming that the patient had a low absolute risk of fracture after the withdrawal of the aromatase inhibitor. CONCLUSION: This case underlines the relative irrelevance of bone mineral density and clinical algorithms in predicting the risk of rebound-associated vertebral fractures after denosumab discontinuation and the strong recommendation to always switch to another antiresorptive therapy (such as zoledronic acid) immediately at the time of denosumab discontinuation.

RESUMO

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has affected millions of people across the globe. Previous coronavirus outbreaks led to worsened symptoms amongst pregnant women, suggesting that pregnant women are at greater risk. OBJECTIVES: Our aim is to investigate the differences in clinical presentation, management, and prognosis of COVID-19 infection in pregnant and non-pregnant women. METHODS: We ran a search on electronic databases and analysis of the relevant articles was done using Revie Manager 5.4. RESULTS: The review consists of nine studies comprising 591,058 women (28,797 pregnant and 562,261 non-pregnant), with most of the data derived from two large studies. The risk of experiencing fever (RR: 0.74; 95% CI: 0.64-0.85), headache (RR: 0.77; 95% CI: 0.74-0.79), myalgia (RR: 0.92; 95% CI: 0.89-0.95), diarrhea (RR: 0.40, 95% CI: 0.39-0.43), chest tightness (RR: 0.86; 95% CI: 0.77-0.95), and expectoration (RR: 0.45; 95% CI: 0.21-0.97) were greater amongst non-pregnant COVID-19-infected women. Pregnant women with COVID-19 were less likely to be obese (RR: 0.68; 95% CI: 0.63-0.73) or have a smoking history (RR: 0.32; 95% CI: 0.26-0.39). COVID-19-infected non-pregnant women had a higher frequency of comorbidity such as chronic cardiac disease (RR: 0.58; 95% CI: 0.44-0.77), renal disease (RR: 0.45; 95% CI: 0.29-0.71), and malignancy (RR: 0.82; 95% CI: 0.68-0.98), compared to COVID-19-infected pregnant women. The risk of ICU admission (RR: 2.26; 95% CI: 1.68-3.05) and requirement of invasive mechanical ventilation (RR: 2.68; 95% CI: 2.07-3.47) were significantly higher amongst pregnant women. CONCLUSIONS: Although the frequency of risk factors and the risk of experiencing clinical symptoms of COVID-19 were higher among non-pregnant women, COVID-19-infected pregnant women had a higher requirement of ICU admission and invasive mechanical ventilation compared to non-pregnant COVID-19-infected women. More well-conducted studies from varying contexts are needed to draw conclusions. Prospero registration: CRD42020204638.

RESUMO

BACKGROUND AND AIM: Recent trends have shown a decline in the rates of human papillomavirus (HPV)-associated cervical cancer in the vaccinated population but there has been a spike in the HPV-associated oropharyngeal, anal and penile cancers in the majority of the unvaccinated population which are young and middle-aged males. Indigenous populations at an international level carry a disproportionate burden of most diseases. The aim of this meta-analysis was to ascertain the worldwide prevalence of HPV infection in Indigenous populations stratified by sex and site and to document the most commonly reported HPV types. METHODS: Published articles on HPV infection in Indigenous populations from PubMed, Scopus, EMBASE and Web of Science were systematically searched from inception until 23 December 2019. RESULTS: A total of 41 studies were included in the final analysis. The pooled worldwide prevalence of HPV infection (for both oral and genital sites, both males and females) in Indigenous populations was 34.2% (95% CI: 28.9%-39.8%). Subgroup analysis (geographical) showed that the pooled prevalence for African Indigenous, American Indigenous and Asian-Oceanic Indigenous populations were 33.0% (95% CI: 12.8%-57.1%), 33.0% (95% CI: 27.4%-38.9%) and 33.3% (95% CI: 0.17.5%-51.3%), respectively. CONCLUSION: There are not enough data on the burden of the infection carried by males especially with respect to highly suspicious sites like oropharynx. Also, we conclude an overall high prevalence of HPV infection in the Indigenous populations and increasing their susceptibility to benign and malignant manifestations of HPV.

RESUMO

OBJECTIVE: To assess long term survival and patient characteristics associated with survival following acute myocardial infarction (AMI) in Australia and New Zealand. DESIGN: Cohort study. SETTING, PARTICIPANTS: All patients admitted with AMI (ICD-10-AM codes I21.0-I21.4) to all public and most private hospitals in Australia and New Zealand during 2009-2015. MAIN OUTCOME MEASURE: All-cause mortality up to seven years after an AMI. RESULTS: 239 402 initial admissions with AMI were identified; the mean age of the patients was 69.3 years (SD, 14.3 years), 154 287 were men (64.5%), and 64 335 had ST-elevation myocardial infarction (STEMI; 26.9%). 7-year survival after AMI was 62.3% (STEMI, 70.8%; non-ST-elevation myocardial infarction [NSTEMI], 59.2%); survival exceeded 85% for people under 65 years of age, but was 17.4% for those aged 85 years or more. 120 155 patients (50.2%) underwent revascularisation (STEMI, 72.2%; NSTEMI, 42.1%); 7-year survival exceeded 80% for patients in each group who underwent revascularisation, and was lower than 45% for those who did not. Being older (85 years or older v 18-54 years: adjusted hazard ratio [aHR], 10.6; 95% CI, 10.1-11.1) or a woman (aHR, 1.15; 95% CI, 1.13-1.17) were each associated with greater long term mortality during the study period, as was prior heart failure (aHR, 1.79; 95% CI, 1.76-1.83). Several non-cardiac conditions and geriatric syndromes common in these patients were independently associated with lower long term survival, including major and metastatic cancer, cirrhosis and end-stage liver disease, and dementia. CONCLUSION: AMI care in Australia and New Zealand is associated with high rates of long term survival; 7-year rates exceed 80% for patients under 65 years of age and for those who undergo revascularisation. Efforts to further improve survival should target patients with NSTEMI, who are often older and have several comorbid conditions, for whom revascularisation rates are low and survival after AMI poor.

RESUMO

OBJECTIVE: Periodontal examinations are time-consuming and potentially uncomfortable for recipients. We modelled if self-reported questions alone, or combined with objective evidence of periodontal bone loss observable from radiographs, are accurate predictors of periodontitis. METHODS: Self-reported data from the Australian National Survey of Adult Oral Heath 2004-06 were compared with clinical periodontal examinations to assess the validity of 8 periodontitis screening questions in predicting moderate/severe periodontitis. To model alveolar bone loss, a proxy variable simulating radiographic clinical attachment level (rCAL) was created. Three multivariable binary logistic regression models were constructed: responses to 8 screening questions alone (Model 1), screening questions combined with 5 classic periodontitis risk indicators (age, sex, smoking status, country of birth, and diabetes status) (Model 2), and the addition of rCAL (Model 3). Predictive validity was determined via sensitivity (Se) and specificity (Sp) scores and graphically represented using area under the receiver operator characteristic curves (AUROC). RESULTS: Data from 3630 participants periodontally examined determined that 32.4% exhibited periodontitis. Periodontitis risk indicators were all significantly associated with periodontitis case status. Six of 8 screening questions (Model 1) were weak periodontitis predictors (Se = 0.28; Sp = 0.89; AUROC = 0.61). Combining 13 variables for (Model 2) improved prediction (Se = 0.55; Sp = 0.81; AUROC = 0.77). The addition of rCAL (Model 3) improved diagnostic capacity considerably (AUROC = 0.86). CONCLUSIONS: Self-reported questions combined with classic risk indicators are "useful" for periodontitis screening. Addition of radiographs markedly improved diagnostic validity. Based on modelling, nondental health care professionals may provisionally screen for periodontitis with minimal training.

RESUMO

BACKGROUND: The incidence of human papillomavirus (HPV)-related oropharyngeal squamous cell carcinomas (OPSCCs) is increasing globally. Common oral conditions such as periodontitis may contribute. We undertook a meta-analysis to quantify the association between periodontitis, oral HPV and OPSCCs. METHODS: Multiple electronic databases were searched until 12 February 2020. Studies conducted in males and/or females aged ≥ 18 years that examined periodontitis, periodontal procedures, oral HPV infection, and where possible, oral cancers, were eligible. Meta-analyses were conducted and the GRADE approach was used to examine the quality of evidence. RESULTS: Of 2709 studies identified, 13 met the eligibility criteria. Five studies could be included in the meta-analyses. There was no significant increase in the odds of high-risk oral HPV infection among individuals with confirmed periodontitis (odds ratio 4.71, 95% confidence interval 0.57-38.97). Individuals with periodontitis had a 3.65 times higher odds of having any type of oral HPV infection compared with those without periodontitis (95% confidence interval 1.67-8.01). The overall body of evidence was rated as low to very-low certainty. CONCLUSION: Meta-analysis confirms there is a positive association between periodontitis and oral HPV infection, although the overall quality of this evidence is low. Evidence for an association between periodontitis and high-risk oral HPV infection is inconclusive.

RESUMO

In the elderly patients, where biopsy-induced complications could outweigh the benefit, the identification of pancreatic masses is generally referred to as a synonymous of pancreatic cancer and patients are dismissed with no further options than palliative and supportive care. Notwithstanding, not all pancreatic tumors are cancers and therefore alternative diagnoses need to be investigated, especially when patients are unfit for invasive diagnostic procedures. Here, we report a case of an aged patient that was admitted to an internal medicine division for a previously diagnosed pancreatic cancer. The reassessment of the diagnosis has allowed identifying the pancreatic mass as a manifestation of focal pancreatitis in the context of an IgG4-related disease. Accordingly, patient was treated with steroids with rapid clinical improvement. This clinical case suggests that autoimmune diseases should always be considered in the differential diagnosis of pancreatic masses of the elderly.

RESUMO

A number of patients with adrenal incidentaloma are exposed to a slight degree of cortisol excess resulting from functional autonomy of the adrenal mass (usually a cortical adenoma). At present, there are only scant data on the unwanted effects of this endocrine condition referred to as subclinical Cushing's syndrome. The aim of the present study was to look for some features of the metabolic syndrome in patients with incidental adrenal adenoma. Forty-one patients (9 men and 32 women) bearing adrenal incidentaloma with typical computed tomography features of cortical adenoma were studied. For both patients and controls, exclusion criteria were age equal to 70 yr or greater, previous history of fasting hyperglycemia, or impaired glucose tolerance (IGT), severe hypertension, current use of medication or concomitant relevant illnesses, and body mass index (BMI) equal to 30 kg/m(2) or greater. Forty-one patients with euthyroid multinodular goiter accurately matched for sex, age, and BMI served for a 1:1 case-control analysis. The study design included an oral glucose tolerance test (75 g) and an endocrine workup aimed at the study of the hypothalamic-pituitary-adrenal axis. Age and BMI were fully comparable between patients (54.0 +/- 10.7 yr, 23.8 +/- 2.4 kg/m(2)) and controls (52.2 +/- 11.6 yr, 23.5 +/- 2.8 kg/m(2)). Fasting glucose and fasting insulin levels were not different between the two groups (4.96 +/- 0.61 mmol/liter vs. 4.88 +/- 0.58 mmol/liter; 67 +/- 34 pmol/liter vs. 59 +/- 32 pmol/liter), but the 2-h postchallenge glucose was significantly higher in patients than in controls (7.43 +/- 2.49 mmol/liter vs. 6.10 plus minus 1.44 mmol/liter, P = 0.01). Fifteen patients (36%) reached the World Health Organization criteria for IGT and two other patients (5%) reached those for diabetes, and 14% of the controls qualified for IGT (P = 0.01). No difference in the lipid pattern was seen between the two groups, but either systolic or diastolic blood pressure were higher in patients (135.4 +/- 15.5 mm Hg vs. 125.0 +/- 15.6 mm Hg, P = 0.003; 82.9 +/- 9.1 mm Hg vs. 75.3 +/- 6.6 mm Hg, P < 0.0001). We calculated the whole-body insulin sensitivity index derived from the oral glucose tolerance test that was significantly reduced in the patients (4.3 +/- 1.7 vs. 5.7 +/- 2.5, P = 0.01). In a multiple regression analysis, 2-h glucose was associated with BMI and midnight cortisol values (r(2) = 0.36, P = 0.002). The comparison of the patients with nonfunctioning adenoma (n = 29) with those with subclinical Cushing's syndrome (n = 12) yielded significant differences as to 2-h glucose and triglyceride levels, which were significantly higher in the second group (7.02 +/- 1.76 mmol/liter vs. 8.72 +/- 3.17 mmol/liter, P = 0.03; 1.06 +/- 0.4 mmol/liter vs. 1.73 +/- 0.96 mmol/liter, P = 0.002), but the insulin sensitivity index was conversely reduced (5.2 +/- 1.4 vs. 2.9 +/- 1.2, P < 0.0001). In conclusion, many patients with incidental adrenal adenoma display altered glucose tolerance, that may be explained by reduced insulin sensitivity, and increased blood pressure levels in comparison with carefully age- and BMI-matched controls. The slight hypercortisolism observed in some such patients may significantly contribute to this state of insulin resistance. Midnight serum cortisol appears as a sensitive marker of the metabolic effects of subclinical Cushing's syndrome.
