Therapeutic Level III.
Therapeutic Level III.Symptomatic irreparable rotator cuff tears pose a challenge for shoulder surgeons. Whilst reverse polarity shoulder arthroplasty is an effective option for older symptomatic patients who have exhausted conservative management, the optimal treatment for younger patients remains controversial. In this article we outline the main tendon transfer options, including anatomical considerations, indications, contraindications, surgical technique, complications and a review of the evidence. Tendon transfers provide an alternative joint-preserving surgical option, but the evidence so far is limited, with a clear need for well-designed comparative studies to confirm their effectiveness.Whale lice (Cyamidae; Amphipoda) are ectoparasitic crustaceans adapted to the marine environment with cetaceans as their host. There are few reports of cyamids occurring in odontocetes from the North Sea, and long-term studies are lacking. Marine mammal health was monitored along the German and Dutch coasts in the past decades, with extensive post mortem investigations conducted. The aim of this study was to analyse archived ectoparasite samples from stranded cetaceans from the North Sea (2010-2019), to determine species, prevalence and impact of ectoparasite infection. Ectoparasites were found on two cetacean species - harbour porpoises (Phocoena phocoena), as the most abundant cetacean species in the North Sea, and on a pilot whale (Globicephala melas), as a rare species here. Prevalence of ectoparasitic crustaceans in cetaceans was low 7.6% in porpoises stranded in the Netherlands (n = 608) and 1.6% in porpoises stranded in Germany (n = 122). All whale lice infections were found on hosts with skin lesions hese differences.Animal movements, especially avian migration, can be a mechanism for the large-scale dispersal and geographic range expansion of parasites. The host-parasite relationships among birds during migration have yet to be fully explored. We characterized the haemosporidian parasite lineages in passerines during spring migration on the Texas coast of the Gulf of Mexico, and identified associations among wintering origin (US, Central America, South America) and foraging height (canopy, understory, ground) and infection status. We examined 743 samples representing 52 species of 10 families over six years, 2014-2019. We used PCR and DNA sequencing of the haemosporidian cytB gene from avian blood samples to determine infection status with the genera Plasmodium and Haemoproteus and characterize the lineages of blood parasites. We found an overall haemosporidian infection prevalence of 48.4% among neotropical migrant and Texas wintering birds. Among families, Icterids had the highest prevalence (75%, 24 individuals, 4 speand the use of individual bird tracking methods to understand infection dispersion over time will allow a more comprehensive understanding of changing avian host-haemosporidian relationships.The prognostic impact of CD20 expression and rituximab therapy in classical Hodgkin lymphoma (cHL) is unclear. Among 310 patients, CD20 was expressed in 66 (22%) cases. The 3-year PFS was 75.1% for CD20+and 70% for CD20- (p = 0.36). The 3-year PFS was 84.7% for the rituximab group and 67.8% for the no rituximab group (p = 0.23). Only constitutional symptoms and positive interim PET/CT were significantly associated with worse outcome, HR 3.2 (1.14-9.01; p = 0.028) and 4.3 (2.27-8.1; p less then 0.0001), respectively. Neither CD20 expression nor rituximab use significantly impacted outcome.
Computed Tomography (CT) scan is a helpful tool to assess the coronary arteries and the great vessels. However, its routine use in the assessment of patients with suspected prosthetic valve dysfunction (PVD) has not been studied thoroughly.

To determine the impact of routine cardiac computed tomography angiography (CCTA) on diagnostic and therapeutic decisions in patients with suspected PVD.

This was a prospective cohort study that was conducted on 50 consecutive patients with suspected PVD who underwent both 64-slice ECG-gated CT and transesophageal echocardiography (TEE). The gold standard was the intraoperative findings. Surgery was performed in forty-six patients. ECG-gated CT showed findings that were not detected by TEE in sixteen patients (32%) namely aortic root abscess, aortic pseudoaneurysm, paravalvular leakage (PVL), sclero-calcific disruption of sutures as cause of PVL, mechanical prosthesis occluder malfunction, an underlying thrombus as cause of malfunction and finally presence of aortic ed after TEE in patients with a high suspicion on PVD.
The aim of the current study is to determine the safety of early discharge (ED) within 48 hours (h) for ST-elevation myocardial infarction (STEMI) patients who underwent primary percutaneous coronary intervention (PPCI) and to define the criteria of low-risk patients that can be considered for ED.

This is a single-center retrospective study that took place at Mohammed bin Khalifa Cardiac Centre in the Kingdom of Bahrain. 301 patients who underwent PPCI between January 2018 and March 2019 were included. Endpoints at 30 days follow-up comprised cardiac re-admission, cardiovascular death, non-fatal myocardial infarction, stroke, and major adverse cardiovascular and cerebrovascular events.

Of the 301 patients included in our study, 74 (24.5%) were discharged within 48 h (group 1) compared with 227 (75.5%) hospitalized for more than 48 h after PPCI (group 2) (<0.0001). In terms of baseline characteristics, group 2 had higher proportions of chronic kidney disease (P = 0.051), mean HbA1c (P = 0.016) and meanted data support the practice of ED, with length of stay even shorter than current guidelines recommendation in selected low-risk patients.
Preserved LV systolic function is a good predictor of early and safe discharge after successful PPCI. The presented data support the practice of ED, with length of stay even shorter than current guidelines recommendation in selected low-risk patients.A 21-years-old with Down syndrome presented with respiratory distress. Initial investigations revealed a cardiac tamponade. On further evaluation, he had positive coronavirus disease-2019 (COVID-19), severe chest infection and severe hypothyroidism. He responded well to urgent pericardiocentesis, levothyroxine, hydrocortisone and tocilizumab.
Coronary artery anatomy frequently affects location of atherosclerotic plaques and subsequent culprit lesions. We sought to clarify whether presence or absence of Ramus Intermedius coronary artery (RI) would affect location of culprit lesions in acute left circumflex (LCX) coronary artery occlusion.

The study included 180 patients, 100 with a diagnosis of non-ST elevation myocardial infarction (NSTEMI) and 80 with ST elevation myocardial infarction (STEMI). All culprit lesions were located in the LCX coronary artery. RI group included 45 patients and the No RI group included 135 patients.

Culprit LCX lesions were similarly located at a comparable distance from LCX ostium in both groups and the presence of RI was not associated with significantly more proximally located culprit LCX lesions (34.7 ± 15.2 mm compared to 30.8 ± 17.9 mm respectively, p > 0.05). The frequency distribution of culprit lesions' distance from LCX ostium showed no significant difference between both groups in any of the segments studied (10 mm each). There was no significant difference between both groups regarding markers of myocardial necrosis size as cardiac biomarkers (peak cardiac troponin-T 1077.4 ± 361.2 pg/dl vs 926 ± 462.2 pg/dl respectively, p = 0.13), (peak creatine kinase-MB 232.2 ± 81 ng/dl vs 194.7 ± 99.2 ng/dl respectively, p = 0.07) or left ventricular ejection fraction (EF 46.3 ± 6.3% vs 48.3 ± 8.3% respectively, p = 0.76).

Presence of RI coronary artery, as an additional flow divider, may not be associated with more proximal culprit lesions, compared to its absence, in cases of acute LCX coronary artery occlusion. Possible underlying pathophysiologic mechanisms remain to be clarified.

Left ventricular diastolic dysfunction (LVDD) in patients undergoing transcatheter aortic valve replacement (TAVR) is associated with poor outcomes; however, the effect of its severity is controversial. We sought to assess the impact of diastolic dysfunction on hospital outcomes and survival after TAVR and identify prognostic factors.

We included patients who underwent TAVR for severe aortic stenosis with preexisting LVDD from 2009 to 2018 (n = 325). Patients with prior mitral valve surgery (n = 4), atrial fibrillation (n = 39), missing or poor baseline diastolic dysfunction assessment (n = 36) were excluded. The primary endpoint was all-cause mortality. 246 patients were included in the study.

The median age was 80 years (25th and 75th percentiles75-86.7), 154 (62.6%) were males and the median EuroSCORE II was 4.3 (2.2-8). Patients with severe LVDD had significantly higher EuroSCORE, and lower ejection fraction (p < 0.001). There was no difference in post-TAVR new atrial fibrillation (p = 0.912), pa those patients were affected by the preoperative clinical state and procedure-related factors.
This study aims to compare the 2017-ACC/AHA hypertension guideline with 2014-JNC-8 guideline in regard to the number of patients who are eligible for treatment and to determine the physicians' adherence and the financial impact of implementing the new guideline.

A cross-sectional observational study was conducted on adult patients who attended the hospital outpatient setting in UAE during January 1, 2018 till February 28, 2018. Adults who are diagnosed with hypertension and those with blood pressure (BP) levels based on two or more readings obtained on two or more different occasions were screened for inclusion into this study and cardiovascular diseases (CVD) risk was calculated. The two guidelines were compared with respect to the number of patients diagnosed with hypertension and eligible for treatment. Results were extrapolated to the UAE population. Financial impact of applying the 2017-ACC/AHA guideline was also evaluated.

In comparison with the JNC-8, the 2017-ACC/AHA guideline would increase the/AHA reflects the concern regarding the increase risk of adverse events.
The current study reveals marked increase in the proportion of patients diagnosed with hypertension in concordance with the 2017-ACC/AHA guideline. This is also will be associated with almost double the number of UAE adults recommended for antihypertensive medications. The poor compliance with the 2017-ACC/AHA reflects the concern regarding the increase risk of adverse events.The novel Coronavirus infection disease is becoming more complex for the humans society by giving death and infected cases throughout the world. Due to this infection, many countries of the world suffers from great economic loss. The researchers around the world are very active to make a plan and policy for its early eradication. The government officials have taken full action for the eradication of this virus using different possible control strategies. It is the first priority of the researchers to develop safe vaccine against this deadly disease to minimize the infection. Different approaches have been made in this regards for its elimination. In this study, we formulate a mathematical epidemic model to analyze the dynamical behavior and transmission patterns of this new pandemic. We consider the environmental viral concentration in the model to better study the disease incidence in a community. Initially, the model is constructed with the derivative of integer-order. The classical epidemic model is then reconstructed with the fractional order operator in the form of Atangana-Baleanu derivative with the nonsingular and nonlocal kernel in order to analyze the dynamics of Coronavirus infection in a better way.
