BACKGROUND: Current national immunisation schedules differ between countries in terms of vaccine formulation, timing of vaccinations and immunisation programme funding and co-ordination. As a result, some HIV infected paediatric population may be left susceptible to vaccine preventable infections. Vaccines used in healthy population should be subjected to high quality ethical research and be explicitly validated for use in children with special vaccination needs such as those infected with HIV...

BACKGROUND: E protein of tick-borne encephalitis virus (TBEV) and other flaviviruses is located on the surface of the viral particle. Domain III of this protein seems to be a promising component of subunit vaccines for prophylaxis of TBE and kits for diagnostics of TBEV. METHODS: Three variants of recombinant TBEV E protein domain III of European, Siberian and Far Eastern subtypes fused with dextran-binding domain of Leuconostoc citreum KM20 were expressed in E...

: As the number of older adults living with HIV continues to increase, understanding how to incorporate geriatric assessments within HIV care will be critical. Assessment of geriatric syndromes and physical function can be useful tools for HIV clinicians and researchers to help identify the most vulnerable older adults and to better understand the aging process in PLWH. This review focuses on the assessment of falls, frailty and physical function, first in the general population of older adults and includes a specific focus on use of these assessments in older adults living with HIV...

Insect studies for different regions are scarce as most of the material is collected in isolation, thus preventing extensive taxonomic listings. Conducting inventories of terrestrial biodiversity in a specific area is an arduous task, with many obstacles: mainly the lack of data on taxonomic and geographical distribution necessary to study them. The aim of this work is to present new contributions to the geographical distribution of Heteroptera in the Pampean, Espinal and Monte phytogeographic provinces, in the central region of Argentina, Southern Cone...

The Ewing's sarcoma family of tumors (ESFT) comprises a number of rare malignant tumors. Standard first-line treatment for patients with these tumors includes chemotherapy with a five-drug regimen of vincristine, doxorubicin (Adriamycin(®)) and cyclophosphamide, alternating with ifosfamide and etoposide (VAC/IE). In cases of inadequate response, there are a number of second-line regimens available. However, further treatment options are required for those patients with disease unresponsive to standard treatment...

Identification of the main reaction coordinates and building of kinetic models of macromolecular systems require a way to measure distances between molecular configurations that can distinguish slowly interconverting states. Here we define the commute distance that can be shown to be closely related to the expected commute time time needed to go from one configuration to the other, and back. A practical merit of this quantity is that it can be easily approximated from molecular dynamics datasets when an approximation of the Markov operator eigenfunctions is available, which can be achieved by the variational approach of conformation dynamics (VAC) or the time-lagged independent component analysis (TICA)...

BACKGROUND: Using electronic medical record (EMR) data for clinical decisions, quality improvement, and research is common. While unhealthy alcohol use is particularly risky among HIV infected individuals (HIV+), the validity of EMR data for identifying unhealthy alcohol use among HIV+ is unclear. Among HIV+ and uninfected, we: (1) assess agreement of EMR and research AUDIT-C at validated cutoffs for unhealthy alcohol use; (2) explore EMR cutoffs that maximize agreement; and (3) assess subpopulation variation in agreement...

External volume expansion of the recipient site by suction has been proposed as a way of improving fat graft survival. The objective of this study was to present an innovative and simple intraoperative external expansion system to enhance small-volume autologous fat grafting (40-80 mL) and to discuss its background and its mechanism of action. In this system, expansion is performed using a complete vacuum delivery system known as the Kiwi VAC-6000M with a PalmPump (Clinical Innovations). The recipient site is rapidly expanded intraoperatively 10 times for 30 seconds each with a negative pressure of up to 550 mm Hg before autologous fat injection...

BACKGROUND: Despite the completion of more than 60,000 transcutaneous aortic valve implantations (TAVI) per year and an approximately 10-15 % incidence of vascular access site complications (VAC), there is a paucity of data on the efficacy and safety of percutaneous VAC treatment. HYPOTHESIS: Percutaneous endovascular treatment will be an effective treatment of VAC and associated with a low rate of surgical repair. Despite stent placement in proximity to the hip joint, endovascular treatment will be only rarely associated with disabling symptoms or complications...

BACKGROUND AND AIMS: Ventriculo-arterial coupling (VAC) reflects the interaction between ventricular performance and effective arterial load. Current criteria for cirrhotic cardiomyopathy focus only on cardiac function without addressing the effect of hyperdynamic, low-resistance circulation. We investigated alterations in VAC in cirrhotic patients and their associations with post-liver transplant all-cause mortality. METHODS: In this single institution cohort study, cirrhotic patients who underwent liver transplantation (LT) (n = 914) were retrospectively compared with healthy matched controls using noninvasively measured end-systolic ventricular elastance (Ees), arterial elastance (Ea), and VAC (Ea/Ees)...

Epigenetic control of human immunodeficiency virus-1 (HIV-1) genes is critical for viral integration and latency. However, epigenetic changes in the HIV-1-infected host genome have not been well characterized. Here, we report the first large-scale epigenome-wide association study of DNA methylation for HIV-1 infection. We recruited HIV-infected (n = 261) and uninfected (n = 117) patients from the Veteran Aging Cohort Study (VACS) and all samples were profiled for 485,521 CpG sites in DNA extracted from the blood...

BACKGROUND: The transradial approach has become the preferred vascular access during conventional coronary angiography (CCA). Hereby, we evaluated the impact of pre-procedural radial artery diameter (RAD), the cross-sectional area (CSA), and the perimeter on vascular complications (VACs). METHODS: We conducted a single-center prospective analysis of 513 patients who underwent CCA. Radial artery ultrasonography was performed before and after CCA to measure the RAD, CSA, and perimeter...

Vacuum-assisted closure (VAC) is gaining popularity in the management of many types of acute and chronic wounds. The use of VAC devices in thoracic surgery is limited, but it appears to be promising in complex cases of empyema thoraces. We report a case of empyema necessitans, in which VAC was used to achieve complete wound healing after open drainage which was communicating with the pleural space.

BACKGROUND: Violence against children (VAC) remains a global problem. The health sector has an opportunity and responsibility to be part of the multi-sector collaboration to prevent and respond to VAC. This review aimed to assess the health sector's response to VAC among Latin American & Caribbean (LAC) countries, particularly as it relates to physical violence, sexual violence, and neglect. METHOD: National protocols for the identification and provision of health care to child survivors of violence, abuse and neglect were solicited in partnership with UNICEF and PAHO/WHO country offices within the LAC region...

Ground state geometries of benzene on crystalline ice cluster model surfaces (Ih) are investigated. It is found that the binding energies of benzene-bound ice complexes are sensitive to the dangling features of the binding sites. We used time-dependent DFT to study the UV spectroscopy of benzene, ice clusters, and benzene-ice complexes, employing the M06-2X functional. It is observed that the size of the ice cluster and the dangling features show minor effects on the UV spectral characteristics. Benzene-mediated electronic excitations of water towards longer wavelengths (above 170 nm) are noticed in benzene-bound ice clusters, where the cross-section of photon absorption water is negligible, in good agreement with recent experimental results (Thrower et al...

OBJECTIVE: To evaluate the level and the persistence of maternal antibodies in infants after maternal immunization with pneumococcal polysaccharide vaccine (Pn23V). METHODS: Pregnant women were assigned to two groups, during routine low-risk pre-natal visits. The first Group (VAC) received the Pn23V vaccine shortly after enrolment at 28 weeks or later, and the second Group (NO_VAC) received no vaccine. To investigate the antibody persistence, we collected blood samples from the mothers after 1 month of delivery and from the infants at 1 and 6 months of age...

Xylem parenchyma cells (VACs) constitute a significant fraction of the xylem in woody plants. These cells are often closely connected with xylem vessels or tracheids via simple pores (remnants of plasmodesmata fields). The close contact and biological activity of VACs during times of severe water stress and recovery from stress suggest that they are involved in the maintenance of xylem transport capacity and responsible for the restoration of vessel/tracheid functionality following embolism events. As recovery from embolism requires the transport of water across xylem parenchyma cell membranes, an understanding of stem-specific aquaporin expression patterns, localization and activity is a crucial part of any biological model dealing with embolism recovery processes in woody plants...

BACKGROUND: Incarceration is associated with increased risk of hypertension and cardiovascular disease mortality. We used data from the Veterans Aging Cohort Study (VACS) to explore the impact of incarceration on blood pressure (BP) control. METHODS: Among hypertensive VACS participants, we measured the association between self-reported recent incarceration or past (not recent) history of incarceration and BP control in the year following the survey. To analyze the association between incarceration and BP control, we used logistic regression models adjusted for sociodemographic characteristics, clinical factors (HIV status and body mass index), and behavioral factors (history of smoking, unhealthy alcohol use, illicit drug use)...
