Abstract Introduction Testosterone deficiency (TD) has been shown to be associated with cardiovascular risk factors and an increased risk of cardiovascular events. Conversely, literature surrounding testosterone replacement therapy (TRT) and major adverse cardiovascular events (MACE) is conflicting. Currently, the Food and Drug Administration requires warnings regarding a possible increased cardiovascular risk for TRTs. Objective This study sought to investigate the association between TD and MACE. It also sought to investigate the association between TRT and MACE using a large population based database. The hypotheses were that TD men will have a higher risk of MACE, while men receiving TRT will also have a higher risk of MACE compared to controls. Methods A propensity-weighted, retrospective cohort study was conducted by accessing provincial health administrative databases. Eligibility criteria included men 18 years and older, with no prior TRT or MACE, who had at least 1 year of provincial health coverage from their index date between April 1st, 1995 to December 31st, 2018. TD was defined as men who had a serum testosterone level between 57-300 ng/dL. TRT was defined as having at least two testosterone prescriptions filled within one year (including capsules, gels, patches, and/or injections). MACE was defined as myocardial infarction, coronary revascularization procedures, ischemic stroke, or hospitalizations for heart failure. Controls were assigned a pseudo-index date at random based on the frequency distribution of index dates in the study group. Logistic regression model that included age, socioeconomic status, index year, diabetes, hypertension, dyslipidemia and renal disease was used to determine the propensity score. Stabilized inverse propensity treatment weighting was then applied to the propensity score. A cox proportional hazard model was used to examine our primary outcome of time to a MACE. Results Among 7918 men with TD and 442286 controls, men with TD were associated with a 87 % higher risk of a MACE (Hazard Ratio 1.76, 1.63 – 1.89) in unweighted and 21% higher risk (Hazard Ratio 1.27, 1.16 – 1.39) in weighted analyses. Among 6893 men receiving TRT and 415377 controls, men receiving TRT were associated with a 76% higher risk of a MACE (Hazard Ratio 1.76, 1.63 – 1.89) in unweighted and 26% higher risk (Hazard Ratio 1.27, 1.16 – 1.39) in weighted analyses. Conclusions This study demonstrates that both TD men and men receiving TRT had a higher risk of MACE as compared to controls. Whether TRT itself increases the odds of MACE requires further elucidation. Our study is limited by its retrospective nature and inability to capture for all confounders.

Abstract Introduction Erectile dysfunction (ED) and cardiovascular disease share similar risk profiles which include: aging, hypertension, diabetes, smoking, obesity, and dyslipidemia. Previous literature has suggested ED as a potential harbinger of future cardiovascular disease. Objective As such, we sought to investigate the association between ED and major adverse cardiovascular events (MACE) using a large population based database. As a secondary objective, we sought to investigate the relationship of place of residence (rural or urban) in regards to the incidence of MACE. Methods A propensity-weighted, retrospective cohort study was conducted by accessing provincial health administrative databases. Eligibility criteria included men 18 years and older, with no prior ED or MACE, who had at least 1 year of provincial health coverage from their index date between June 1st 1996 to March 31st 2018. ED was defined as having at least two ED prescriptions filled within one year (including oral, intraurethral, and/or injection therapies). MACE was defined as myocardial infarction, coronary revascularization procedures, ischemic stroke, or hospitalizations for heart failure. We then classified study groups into ED Urban, ED Rural, No ED Urban and No ED Rural. Multiple logistic regression model that included age categories, socioeconomic status, index year, diabetes, hypertension, dyslipidemia and renal disease was used to determine the propensity score. Stabilized inverse propensity treatment weighting was then applied to the propensity score. A cox proportional hazard model was used to examine our primary outcome of time to a MACE. Results The median time to a MACE was 2721, 2620, 2520, and 2438 days in the ED Urban (N=32,138), ED Rural (N=17,821), No ED Rural (N=145,209) and No ED Urban (N=233,073) study groups, respectfully. The ED Rural, ED Urban and No ED Rural study groups had a 54% (Hazard Ratio [HR] 1.54, 95% CI [1.45 – 1.63]), 26% (HR 1.26, 95% CI[1.20 – 1.32]) and 14% (HR 1.14, 95% CI[1.11 – 1.18]) higher risk of a MACE event as compared to the No ED Urban group, in weighted analyses, respectfully. Among individuals with ED, men from a rural setting had a 22% (HR 1.22, 95% CI[1.14 – 1.32]) higher risk of a MACE event, as compared from an urban setting. Conclusions Our study demonstrates that men diagnosed with ED had a higher risk of MACE as compared to controls. ED is demonstrated to be an independent risk factor for MACE when controlling for comorbidities. In addition, men residing in rural communities had a higher risk of MACE as compared to other urban counterparts. It is imperative for health care professionals who manage patients with ED to discuss the risk of future cardiovascular disease and identify comorbid conditions to mitigate risk.

Hidradenitis suppurativa (HS) is a condition that commonly presents with recurrent abscesses, nodules, and draining tunnels. Despite drainage and odor occurring as common symptoms that are associated with poorer quality of life, and patients included in the Hidradenitis SuppuraTiva cORe outcomes set International Collaboration (HISTORIC) highly supported that drainage should be recommended in the core domain set, there are no validated instruments to measure drainage.

The authors report the results of a Bayesian network meta-analysis of randomized controlled trials (RCTs) comparing supervised exercise therapy alone (SET), percutaneous tranluminal angioplasty (PTA) alone, or a combination of SET and PTA for the treatment of intermittent claudication. Medical databases were searched with the PRISMA statement and 39 RCTs (including five 3-arm studies) comprising 2,983 patients with 12 months median follow-up (range, 3–24 months) were analysed in total. Outcome measures included improvements of Maximal Walking Distance capacity (MWD; meters on treadmill) and Quality of Life (QoL; SF-36 and EQ-5D instruments) compared to best medical therapy (BMT) as the anchor control treatment. Bayesian random effects models were employed (WinBUGS). There were significant improvements of MWD with PTA (+85 m, 95%CrI: +4 to +170), SET (+180m, 95%CrI: +130 to +230) and PTA+SET (+290m, 95%CrI: +180 to +390). SET was better than PTA alone (MWD difference +85m, 95%CrI: +16 to +170). PTA+SET were the best treatment with an MWD difference over SET of +110m (95%CrI: +16 to +200). Quality of life was significantly and strongly improved only in case of PTA+SET (QoL Cohen's d standardized effect size 1.8; 95%CrI: 0.21 to 3.4). Results were stable on sensitivity and consistency analyses without any significant publication bias. Healthcare systems need to invest in supervised exercise programmes as the first standalone treatment for intermittent claudication and in order to augment the results of peripheral revascularization.

AbstractObjective:This paper reports a rare case of cerebrospinal fluid leak due to a Hyrtl's fissure and discusses the non-operative management of the case.Background and case report:Cerebrospinal fluid otorrhoea is a rare phenomenon arising from an abnormal communicating tract between the subarachnoid space and middle ear. Affected patients are at a higher risk of developing meningitis and other neuro-otological complications. There are four common congenital causes of cerebrospinal fluid otorrhoea in the region of a normal labyrinth. This paper describes a case of cerebrospinal fluid in the middle ear resulting from a Hyrtl's fissure, which resolved spontaneously.Conclusion:A literature search indicated this to be the first case with such a resolution without the need for any intervention.

IntroductionAortic arch aneurysm repair continues to pose a formidable technical challenge in a patient population with significant co-morbidity.ReportWe present a successful endovascular repair of an 8.4 cm aortic arch aneurysm, in a 74 year old man, who's previous median sternotomy showed signs of delayed healing, precluding open repair.DiscussionApplied endovascular techniques obviated the need for aortic clamping, cardiac bypass, or hypothermic circulatory arrest, via an approach that was potentially infected.

Previous studies have demonstrated the existence of a circulating myocardial depressant substance during human septic shock. We have recently identified this substance as a synergistic combination of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). This study utilized an in vitro cardiac myocyte assay to evaluate the potential mechanistic role of nitric oxide (NO) and cGMP in depression of myocyte contractility induced by TNF-α, IL-1β, TNF-α + IL-1β (at low concentrations), and human septic shock serum (HSS). TNF-α, IL-1β, TNF-α + IL-1β, and each of 5 sera from patients with acute septic shock caused depression of both maximum extent and peak velocity of cardiac myocyte shortening and an increase in intracellular cGMP concentration during 30 min of exposure (minimum P < 0.01). NO synthetase (NOS) and guanylate cyclase inhibitors such as N-methyl-l-arginine (l-NMA) and methylene blue prevented these effects; an excess ofl-arginine withl-NMA restored them (minimum P < 0.01). In contrast,d-arginine failed to reestablish cytokine-induced myocyte depression and cGMP accumulation prevented byl-NMA. Exposure of myocytes to TNF-α, IL-1β, or TNF-α + IL-1β produced a concentration-dependent increase in intracellular cGMP that paralleled the depression of cardiac myocyte contractility (minimum P < 0.001). In addition, TNF-α, IL-1β, TNF-α + IL-1β, or HSS application to cardiac myocytes resulted in increased NO gas generation, which was inhibited byl-NMA (minimum P < 0.01). Furthermore, unstimulated cardiac myocytes were shown to harbor constitutive but not inducible NOS activity. These data suggest that the sequential generation of NO by a constitutive NOS and cGMP by guanylate cyclase represents an important mechanism of cardiac myocyte depression by TNF-α, IL-1β, TNF-α + IL-1β, and the myocardial depressant substance(s) of septic shock.

Background: Digital recording of echocardiographic studies is on the clinical horizon. However, full digital capture of complete echocardiographic studies in traditional video format is impractical, given current storage capacity and network bandwidth. To overcome these constraints, we evaluated the diagnostic image quality of digital video by using MPEG (Motion Picture Experts Group) compression.Methods and Results: Fifty-eight complete, consecutive studies were recorded simultaneously with the use of MPEG-1 and sVHS videotape. Each matched MPEG and sVHS study pair was reviewed by two from a total of six readers, and findings were recorded with the use of a detailed, computerized reporting tool. Intrareader and interreader discrepancies were characterized as major or minor and analyzed in total and for specific subgroups of findings (left and right ventricular parameters, valvular insufficiency, and left ventricular regional wall motion). Intrareader discrepancies were reviewed by a consensus panel for agreement with either MPEG or sVHS findings. There was an exact concordance between MPEG and sVHS readings in 83% of findings. The majority of discrepancies were minor, with major discrepancies in only 2.7% of findings. There was no difference in the rate of consensus panel agreement with MPEG or sVHS for instances of intrareader discrepancy, either in total or for any subgroup of findings. Interreader discrepancy rates were nearly identical for both MPEG and sVHS.Conclusions: MPEG-1 digital video is equivalent to sVHS videotape for diagnostic echocardiography. MPEG increases the range of practical options for digital echocardiography and offers, for the first time, the advantages of digital recording in a familiar video format.
