With the coronavirus disease 2019 (COVID-19) pandemic in the United States, a majority of states have instituted “shelter-in-place” policies effectively quarantining individuals—including pregnant persons—in their homes. Given the concern for COVID-19 acquisition in health care settings, pregnant persons with high-risk pregnancies—such as persons living with HIV (PLHIV)—are increasingly investigating the option of a home birth. Although we strongly recommend hospital birth for PLHIV, we discuss our experience and recommendations for counseling and preparation of pregnant PLHIV who may be considering home birth or at risk for unintentional home birth due to the pandemic. We also discuss issues associated with implementing a risk mitigation strategy involving high-risk births occurring at home during a pandemic.

Embedded BHs and multipole globules: clustered misaligned thick accretion disks around static SMBHs
Authors: Pugliese D , Stuchlík Z 
Published: June 2020

Abstract
We investigate clusters of misaligned (inclined) tori orbiting a central static Schwarzschild black hole. To this purpose we considered a set of geometrically thick, pressure supported, perfect fluid tori analyzing purely hydrodynamic models. We study the tori collision emergence and, consequently, the stability properties of the aggregates composed by tori with different inclination angles relative to a fixed distant observer. The aggregate of tilted tori is modeled as a single orbiting configuration, by introducing a leading function governing the distribution of toroids around the black hole attractor. Eventually the tori agglomerate can be seen, depending on the tori thickness, as a (multipole) gobules of orbiting matter, with different toroidal spin orientations , covering the embedded central black hole. These systems are shown to include tori with emerging instability phase related to accretion onto the central black hole. Therefore we provide an evaluation of quantities related to tori energetics such as the mass-flux, the enthalpy-flux, and the flux thickness depending on the model parameters for polytropic fluids. Consequently this analysis places constraints on the existence and properties of tilted tori and aggregate of misaligned disks. Some notes are included on aggregates including proto-jets, represented by open cusped solutions associated to the geometrically thick tori.

Groundwater Change Detection by Gravity Measurement on Northern Coast of Java: A Case Study in Semarang City of Central Java of Indonesia
Authors: Sabri Laode M , Sudarsono Bambang , Aryadi Yadi 
Published: June 2020

Abstract
Northern part of Semarang city is affected by tidal flood due to land subsidence. Land subsidence is triggered by soil compaction and massive groundwater extraction. One of famous methods in analysing groundwater is gravity method. This research aim to present groundwater change in Semarang city based on gravity measurement and to analyze problems related to equipment and groundwater behaviour. Gravimeter Scintrex CG-5 was applied for gravity measurement. Geographic coordinates were measured using GNSS receiver namely TopCon HiperII. This research occupied SRTM90 Plus and regional geology map at 1:100.000 scales. Groundwater change was detected by differentiating simple Bouguer anomaly of 2014 and 2016. Data in gravity unit were then converted by coefficient of 0.012 mgal per meter. Simple Bouguer anomaly in 2014 ranged from -3.423 mgal to 19.874 mgal, while 2016 data ranged from -3.427 mgal to 19.835 mgal. Discrepancy of gravity anomaly ranged from -0.326 mgal to 0.209 mgal. The data confirmed that groundwater change ranged from -27.160 m to 17.408 m. Groundwater depletion occurred commonly on alluvial plain in northern area, while recharging could be found in some locations in southern part. This research concluded that gravity measurement had potential to be applied for groundwater detection in coastal areas.
MeSH-Based Semantic Indexing Approach to Enhance Biomedical Information Retrieval
Authors: Kammoun Hager , Gabsi Imen , Amous Ikram 
Published: June 2020

AbstractOwing to the tremendous size of electronic biomedical documents, users encounter difficulties in seeking useful biomedical information. An efficient and smart access to the relevant biomedical information has become a fundamental need. In this research paper, we set forward a novel biomedical MeSH-based semantic indexing approach to enhance biomedical information retrieval. The proposed semantic indexing approach attempts to strengthen the content representation of both documents and queries by incorporating unambiguous MeSH concepts as well as the adequate senses of ambiguous MeSH concepts. For this purpose, our proposed approach relies on a disambiguation method to identify the adequate senses of ambiguous MeSH concepts and introduces four representation enrichment strategies so as to identify the best appropriate representatives of the adequate sense in the textual entities representation. To prove its effectiveness, the proposed semantic indexing approach was evaluated by intensive experiments. These experiments were carried out on OHSUMED test collection. The results reveal that our proposal outperforms the state-of-the-art approaches and allow us to highlight the most effective strategy.
LUISA: Decoupling the Frequency Model From the Context Model in Prediction-Based Compression
Authors: Fulber-Garcia Vinicius , Sardi Mergen Sérgio Luis 
Published: June 2020

AbstractPrediction-based compression methods, like prediction by partial matching, achieve a remarkable compression ratio, especially for texts written in natural language. However, they are not efficient in terms of speed. Part of the problem concerns the usage of dynamic entropy encoding, which is considerably slower than the static alternatives. In this paper, we propose a prediction-based compression method that decouples the context model from the frequency model. The separation allows static entropy encoding to be used without a significant overhead in the meta-data embedded in the compressed data. The result is a reasonably efficient algorithm that is particularly suited for small textual files, as the experiments show. We also show it is relatively easy to built strategies designed to handle specific cases, like the compression of files whose symbols are only locally frequent.
Seasonal Development, Cumulative Growing Degree-Days, and Population Density of Spotted Lanternfly (Hemiptera: Fulgoridae) on Selected Hosts and Substrates
Authors: Liu Houping 
Published: June 2020

Abstract
Seasonal development, cumulative growing degree-days (CUMDD10), and population density of Lycorma delicatula (White) were studied through weekly sampling of 30 plants (5 plants/species, 3 common plus 3 site-specific species per site) at six sites in Pennsylvania in 2019. In total, 24,159 L. delicatula (1,987 egg masses, 1,068 first instars, 239 second instars, 153 third instars, 410 fourth instars, and 20,302 adults) were recorded in 28 wk. Seasonal development followed similar pattern at all sites despite differences in starting, peaking, and ending time for specific life stages. The average CUMDD10 requirement for the onset of the first instars, second instars, third instars, fourth instars, adults, and eggs was 270, 465, 645, 825, 1,112, and 1,825, respectively. Population density ranged from 0 to 207.4, 0–298.9, and 0–9.6/m2 for nymphs, adults, and egg masses, respectively. Significant difference in population density was found between sites, hosts/substrates, and sampling weeks. Favored oviposition substrates included tree-of-heaven and black birch despite egg masses being laid on many other surfaces. Nymphs fed on different hosts in early stages but preferred American beech, tree-of-heaven, black birch, and multiflora rose. Adults were predominately found on tree-of-heaven with preoviposition surge on black birch and red maple. Sizable nymph and adult populations persisted on summer grape throughout the season. Tree-of-heaven played an irreplaceable role in the seasonal development and life history of L. delicatula in the field. Survey and detection activities should focus on tree-of-heaven with management efforts directed to aggregating adults for maximum efficacy.
Louis Sohn’s Legacy
Authors: Johnstone Ian 
Published: June 2020

Abstract
Louis Sohn was an émigré scholar who fled Poland for the USA in 1939, two weeks before the Nazis invaded. His most widely known work is World Peace through World Law, co-written with Grenville Clark, a vision for a reconstructed United Nations. Writing at a time when political realism was ascendant in the USA, Sohn was labeled an ‘idealist’. Yet a strain of pragmatism also runs through his scholarship, leading many to praise him as one of the architects of modern international law. As a scholar-practitioner with a mission to help build the post-World War II international order, little overt legal theorizing appears in his work. But a close reading reveals ideas that drew implicitly on extant theory or were developed by later theorists without reference to Sohn’s writing. To help frame the analysis, this article situates Sohn’s writing in two strands of theoretical literature: pre-positivist, positivist and ‘post-positivist’ approaches to law-making by international organizations; and functionalist, constitutionalist and deliberative approaches to the powers of, and constraints on, those organizations. Sohn does not fall neatly into any of those categories; instead, fragments of his work can be found at many points along each spectrum. While the fragments do not add up to a coherent whole, the theoretical contributions of this ‘pragmatic idealist’ are greater than meets the eye.
Beyond CHA2DS2-VASc in atrial fibrillation: the atrium and the risk of stroke
Authors: Boccanelli Alessandro 
Published: June 2020

Abstract
Pathology affecting the atria have a significant impact on the occurrence of arrhythmias and the risk of stroke. The causal relationship between atrial fibrillation (AF) and ischaemic stroke has been challenged by the recent uncovering of the lack of temporal association between thrombo-embolic cerebral events and paroxysmal AF or tachycardia. General conditions, such as the one considered in the definition of the CHA2DS2-VASc score, or specific atrial pathology (also independently occurring), could predispose to cerebral embolism.
Percutaneous mitral valve prostheses: 2019 update
Authors: Bellini Barbara , Colombo Antonio 
Published: June 2020

Abstract
During the last few years, there has been significant advances in the treatment of patients with severe mitral incompetence either too high risk for surgery or inoperable, this because of the improvements in percutaneous mitral valve prostheses, as alternative to the transcatheter mitral repair techniques. Percutaneous mitral valve replacement offers several advantages over the repair techniques, such as the opportunity to treat mitral valve with different anatomic characteristics, even the more complex ones, and the occasion to correct completely mitral regurgitation. The development of such prostheses has been a long process, still on the making. During the initial stages of the procedure, the transapical approach was preferred. On the other hand, the transseptal approach, which has already been used in some patients, is the proper development path for this transcatheter technique. Many valvular prostheses have been produced, each using a different mechanism for secure anchoring and elimination of regurgitation. Early mortality for this procedure, although decreasing since the preliminary studies, is still high, not only because the technology is still in its initial phase but also for the very high risk of the patients treated. It is foreseeable, though, that in the near future, as the technology and patients selection improves, better results will follow.
Long-term injury after Takotsubo syndrome (stress cardiomyopathy)
Authors: Vassiliki’ Coutsoumbas Gloria , Gallo Pamela , Zagnoni Silvia , Di Pasquale Giuseppe 
Published: June 2020

Abstract
Takotsubo syndrome is a clinical condition characterized by transient impairment of left ventricular contractility, in association with symptoms, increase in indices of myocardial necrosis, as well as electrocardiographic changes, but without a coronary culprit lesion, and often after a significant psychological or physical stress. Albeit very similar to acute coronary syndrome (ACS) as far as presentation and clinical course, Takotsubo syndrome was considered, up until recently, a condition with very favourable long-term prognosis, in view of the frequent complete functional recovery. More recently, several retrospective observational studies as well as registers, unexpectedly called attention to a significant incidence of major adverse cardiovascular events, not limited to the recovery period but also during the long-term follow-up, in a way very similar to the outcome of patients after ACS. Several negative prognostic factors have been isolated, such as physical stress as trigger of the condition, the presence of severe left ventricular dysfunction, and the consequent cardiogenic shock during the acute phase. These factors are able to classify better the patient’s prognosis, both in the short- and long-term, and identify patients requiring a more stringent clinical follow-up, considering the higher likelihood of adverse cardiovascular events.
Subclinical atherosclerosis: how and when to treat it?
Authors: Gatto Laura , Prati Francesco 
Published: June 2020

Abstract
Atherosclerosis is a condition characterized by a long, initial, asymptomatic phase. Progression of disease could lead to acute coronary events, such as acute myocardial infarction, unstable angina, or sudden cardiac death. However, there are imaging techniques, namely vascular echography and assessment of coronary calcium, capable to make the diagnosis of atherosclerosis at an early stage. There are several studies demonstrating the ability of statins to delay, and in some situation even revert the progression of this condition. Subclinical atherosclerosis is highly prevalent in people with optimal control of the risk factors, and the imaging techniques have been shown to provide an added value over the traditional risk factors: by identifying directly the condition, these techniques allow the reclassification of low-risk to intermediate- or high-risk subjects, thus directing the primary prevention therapeutic strategies, based on high efficacy statins, aimed at delaying or reversing the progression of the disease.
The extended heart: cardiac surgery serving more hospitals
Authors: Massetti Massimo , Chiariello Giovanni Alfonso 
Published: June 2020

Abstract
The Heart Team is becoming ever more central in delivering cardiovascular care, embodying a modern aspect of medical practice, designed to place the patient at the ‘center’ of a team with different specialists, all contributing to the definition of the most appropriate therapeutic actions. We prospectively analyzed 200 consecutive patients (2015–2017). Patients were evaluated independently by a cardiologist and a cardiac surgeon, each deciding the most appropriate therapeutic action. At a later time, the same patient, was evaluated by the Heart Team. For the first 100 patients the rate of concurrence between cardiologist and cardiac surgeon as well as among each specialist and the Heart Team, was relatively low (51 and 42% respectively). For the following 100 patients the concurrence rate was significantly higher (75 and 70% respectively). The systematic and collegial discussion of the patients in the contest of the Heart Team, steered toward an evolution of each specialist in the group settings. The Electronic Heart Team (e-Heart Team) employing video conference support, applied to the first 65 patients with promising results, represent a further advancement in the delivery of care, by reducing the distance from the ‘Hub’ center, and the specialist in the ‘Spoke’ facility, who from simple source of the patient, now becomes an essential part of the therapeutic decision process. The Heart Team environment can deeply affect patients management and improve treatment results, by sharing the expertise and overcoming the limitations of the individual disciplines, thus reaching the common goal of the patient's best available treatment.
A new therapy for transthyretin amyloidosis, no longer an orphan condition
Authors: Quarta Candida Cristina , Tinuper Anna Laura , Milandri Agnese , Gagliardi Christian , Caponeti Giuseppe , Rapezzi Claudio 
Published: June 2020

Abstract
Amyloid cardiomyopathy is a condition characterized by intra-myocardial deposit of protein-like material, in fibrillar shape (amyloid), which presence determine a progressive thickening and stiffening of the cardiac walls leading to a cardiac dysfunction. The proteins most often involved with cardiac amyloid are the light chains of the immunoglobulin, typical of amyloidosis AL, and transthyretin, responsible for transthyretin amyloidosis, in both its forms, hereditary and wild type. An accurate estimate of the incidence of cardiac amyloidosis is still difficult due to the variety and complexity of the clinical presentation of the condition. Nonetheless, the condition has stimulated the interest of the scientific community, so that a specific diagnostic path has been developed, beginning from the clinical suspicion and first-line testing, such as electrocardiogram, echocardiogram, and blood work, to progress to the diagnostic confirmation using more sophisticated testing such as magnetic resonance, scintiscan, and eventually cardiac biopsy. To understand and recognize this condition is very important, stemming from the availability of ‘aetiology oriented therapies’ (designed to prevent, control and possibly regress amyloid deposition), which should be added to the ‘supportive therapies’, used for the treatment of the complication of the condition, namely heart failure.
De-escalation therapy after acute coronary syndrome: is it reasonable to switch from prasugrel (or ticagrelor) to clopidogrel early?
Authors: Masiero Giulia , Rossini Roberta 
Published: June 2020

Abstract
Dual antiplatelet treatment (DAPT) is the treatment of choice to prevent atherothrombotic events in patients with acute coronary syndrome (ACS) treated with percutaneous interventions (PCIs). The availability of different P2Y12 inhibitors set the stage for costum made DAPT, as to achieve the highest profile of safety and efficacy. The de-escalation therapy for the newer and more powerful antiplatelet drugs, such as ticagrelor and prasugrel, to clopidogrel, is a strategy for patients with recent ACS, unfit for continuing DAPT for their high risk of bleeding, or side effects, or socio-economic reasons, but without a prohibitive ischaemic risk. There is a need for compelling clinical evidences able to provide the clinical cardiologist with the necessary information to decide the best antiplatelet strategy for each individual patient.
Transcatheter aortic valve implantation: how to decrease post-operative complications
Authors: Ina Tamburino Claudia , Barbanti Marco , Tamburino Corrado 
Published: June 2020

Abstract
Transcatheter aortic valve implantation (TAVI) is a therapeutic option widely used for the treatment of severe aortic stenosis in the elderly. Careful pre-procedural screening, operator experience, and technological innovations, accounted for a safe, reliable, and standardized procedure. To further decrease post-operative complications, few steps are important: careful planning of the procedure by the Heart Team, clinical and diagnostic evaluation including electrocardiogram, echography, and computed tomography of the heart and great vessels. This approach will allow a selection of ideal candidates for the procedure, the best vascular approach, the selection of patients candidates for early discharge, and last but not least, simplification of the TAVI procedure. Although the procedure is reaching the ‘simplicity’ of coronary interventions, it should always be kept in mind the possibility, albeit remote, that life-threatening complication could ensue, requiring the prompt intervention of the cardiovascular surgeon.
A revolution in stroke therapy: reperfusion therapy effective even if late
Authors: Toni Danilo , Risitano Angela , Gentile Luana 
Published: June 2020

Abstract
Arterial recanalization procedures after ischaemic stroke, are now well-established treatments, within 5 h for systemic thrombolysis, and 6 h for the endovascular treatment. Ischaemic stroke with uncertain time of symptoms onset, account for 14–27% of the cases, the vast majority of which occur just after waking up, thus it is impossible to derive an exact timeline. Accordingly, these patients are frequently not eligible for acute treatment. The results of three recent trials, DAWN, DEFUSE 3, and WAKE-UP, provided the basis for a revolution in the selection of patients eligible for late revascularization, and revealed an increase in the rate of functional independence for these patients at 90 days (mRS 0–2). Advanced neuroimaging techniques have been shown to be of utmost importance in the definition of the cerebral tissue window. A wider application of these imaging techniques and standardization of the parameters of images acquisition would provide for a significant advancement in the management of ischaemic stroke in the emergency setting.
