Two conformal-skin carpet cloaks working for partial- and full-azimuth plane operation are respectively fabricated on trapezoid and pyramid platforms via 3D printing. Experimental results are in good agreement with numerical simulations and both demonstrate the polarization-insensitive cloaking within a desirable bandwidth. Our approach paves a deterministic and robust step forward to the realization of interfacial, free-form, and full-polarization cloaking for a realistic arbitrary-shape target in real-world applications.
In the attempt to reactivate the economy after several months of the pandemic generated by COVID-19, several South American countries have been forced to attenuate the restriction measures created to prevent contagion, leaving all the responsibility to citizens to safeguard their lives. Faced with this situation, the objective of the work was to promote good prevention practices against COVID-19 in the general population to avoid the collapse of the public health system.

An exploratory review on prevention measures against COVID-19 was carried out in the databases Elsevier, Pubmed, Wiley, Scopus, Scielo and, in general, in academic Google, to obtain gray information.

The role of seven individual protection and prevention measures and barriers to stop the advance of community infections by COVID-19 were described and analyzed. Studies showed that the use of preventive measures can play a critical role in containing the pandemic. However, they can also provide a false security of protection, predisposing to neglect the correct use and handling of all containment measures.

Given the drastic rise in infections and deaths from COVID-19 in Latin America, it becomes necessary to continue with biosecurity campaigns so that citizens are clear that prevention is an integrated process and that the use of one measure does not replace another.

LAA ostial stenosis can be classified into 2 types one is idiopathic and the other is a complication after incomplete surgical LAA ligation. The former one is even rarer and only 12 cases have previously been reported. CASE REPORT An asymptomatic young woman was found at a medical checkup to have an abnormal jet signal in the left atrium on transthoracic echocardiography. TEE revealed that the abnormal signal originated from a narrowed orifice of the LAA. There were no other cardiac abnormalities in this woman. Unlike the previously reported cases, our case had LAA ostial stenosis detected by transthoracic echocardiography but not by TEE. CONCLUSIONS We describe a case of anatomic narrowing of the LAA orifice in a young woman. This was a first-ever case of idiopathic LAA ostial stenosis that was detected by transthoracic echocardiography. Because of the very small number of such cases reported, it remains unknown whether anticoagulation is required to prevent intra-atrial thrombus formation.The high infectivity and severity of SARS-CoV-2 infection (COVID-19), and our limited understanding of the biology of the novel coronavirus, as well as the lack of an effective treatment for COVID-19, have created a global pandemic. Those most likely to become seriously ill with COVID-19 are adults, especially the elderly and those who are already weak or sick. At present, a specific drug for treatment of COVID-19 has not been developed. This, combined with the typical coexistence of a variety of chronic diseases in elderly patients, makes treatment challenging at present. In addition, for elderly patients, COVID-19 isolation measures during the epidemic can easily lead to psychological problems. Thus, how to manage elderly patients has become a focus of social attention in the current circumstances. This article reviews the effects of COVID-19 and makes management suggestions for elderly patients during this epidemic period. In addition to the elderly, critically ill people are also highly susceptible to this novel coronavirus. For elderly COVID-19 patients, antiviral therapy, immune regulation, and even auxiliary respiratory therapy can be given after a comprehensive evaluation of the disease. With the approval and use of COVID-19 vaccines, it is reasonable to expect that we can conquer SARS-CoV-2.BACKGROUND Hand-assisted laparoscopic donor nephrectomy (HALDN) is frequently performed in living kidney transplantation donors. This study investigated the efficacy and safety of HALDN for living donors with abdominal surgical histories. MATERIAL AND METHODS A total of 573 living kidney donors underwent donor nephrectomies for living donor kidney transplantation between January 2008 and May 2015. Eighteen donors underwent open donor nephrectomy and were excluded from analyses. Left HALDN was performed in 533 donors, including 44 donors with abdominal surgical histories and 489 donors without abdominal surgical histories. Right HALDN was performed in 22 donors, including 11 donors with abdominal surgical histories and 11 donors without abdominal surgical histories. Graft quality including the lengths of arteries, veins and ureters, time to initial urination, recipient complications, and recipient estimated glomerular filtration rate (eGFR) and operation quality including warm ischemic time, blood loss, operation duration, donor complications and donor eGFR, were compared between donors with and without abdominal surgical histories in the left and right HALDN groups. RESULTS The metrics of graft and operation quality were similar between living kidney donors with and without a history of abdominal surgery who underwent left or right HALDN. CONCLUSIONS The efficacy and safety of HALDN were not impaired by abdominal surgical histories.
Despite antiretroviral therapy (ART)-mediated viral suppression, people with human immunodeficiency virus (HIV) (PWH) have increased morbidity and mortality. Immune activation and inflammation persist on ART and predict these complications. Over 90% of PWH have cytomegalovirus (CMV) co-infection, and CMV is considered a plausible contributor to this persistent immune activation.

A detailed understanding of the link between CMV and multimorbidity is needed, particularly as research moves toward identifying potential targeted therapeutics to attenuate inflammation-mediated morbidity and mortality in treated HIV. We review the literature on the association between CMV and immune activation as well as multiple end-organ complications including cardiovascular disease, venous thromboembolic disease, metabolic complications, gastrointestinal dysfunction, central nervous system involvement, birth sex-related differences, and the relation to the HIV reservoir. We conclude with a discussion of ongoing therapeutic efforts to target CMV.

As CMV is a plausible driver of multiple comorbidities through persistent immune activation in treated HIV, future research is needed and planned to address its causal role as well as to test novel therapeutics in this setting.

Older adults account for the majority of people with HIV (PWH) in high-income countries and have increasingly complex clinical profiles related to premature aging. Frailty is an important geriatric syndrome affecting a minority of PHW. Frailty negatively affects PHW's clinical status and quality of life. This review will update care providers on the current state of frailty that limits the healthspan of PWH.

Ongoing low-level HIV replication in treated PWH leads to immune activation and chronic inflammation contributing to the destabilization of normally autoregulated physiologic systems in response to environmental and biologic challenges characteristic of frailty. Understanding these underlying mechanisms will determine potential intervention options. Potentially reversible risk factors that promote progression to and reversion from the dynamic state of frailty are being studied and will help prevent frailty. Simple assessment tools and treatment strategies for frailty are being adapted for aging PWH.

Insight into underlying biologic mechanisms and adapting proven geriatric principles of interdisciplinary care will inform the healthy aging of PWH.

The present review aims to decipher common co-morbidities faced by people living with HIV in low- to middle-income countries, and in particular the sub-Saharan region, which hosts the majority of the HIV burden worldwide.

Well-controlled chronic HIV disease is strongly associated with an increased risk of developing cardiovascular disease. This is partly due to the natural aging process, however recent studies show that using antiretroviral therapy as well as the HIV disease itself may be predisposing factors to the development of cardiovascular diseases, creating a new burden for healthcare facilities in the region. Furthermore, newly completed studies assessing inflammation marker albuminuria and age-related syndrome frailty have been found in a higher prevalence than in non-HIV people, with increased morbidity and mortality.

As antiretroviral medication continues to be well supplied in the region and well tolerated by patients living with HIV, this group is now reckoning with cardiovascular ailments faced by all ageing population therefore there is a need for cardiovascular care systems to be better integrated within the existing, well-performing HIV care cascade to address this burden.

The aim of this study was to examine current literature regarding effects of physical or cognitive training and simultaneous (dual-task) physical and cognitive training on cognition in adults surviving an intensive care unit (ICU) stay.

Systematic mapping.

A literature search was conducted to examine effects of physical and/or cognitive training on cognitive processes.

Few studies targeted adults surviving ICU. Independently, physical and cognitive interventions improved cognition in healthy older adults with and without cognitive impairment. Simultaneous interventions may improve executive function. Selumetinib inhibitor Small sample size and heterogeneity of interventions limited the ability to make inferences.

Literature supports positive effects of single- and dual-task training on recovering cognition in adults. This training could benefit ICU survivors who need to regain cognitive function and prevent future decline.

With the growing number of ICU survivors experiencing cognitive deficits, it is essential to develop and test interventions that restore cognitive function in this understudied population.
