Long-Term Adoption of Televisits in Nursing Homes During the COVID-19 Crisis and Following Up Into the Postpandemic Setting: Mixed Methods Study.

Background: There is growing evidence that telemedicine can improve the access to and quality of health care for nursing home residents. However, it is still unclear how to best manage and guide the implementation process to ensure long-term adoption, especially in the context of a decline in telemedicine use after the COVID-19 crisis.

Objective: This study aims to identify and address major challenges for the implementation of televisits among residents in a nursing home, their caring nurses, and their treating general practitioners (GPs).

25 years International Bladder Cancer Network (IBCN): The past, the present, and the future.

In 1997 an international group of scientists organized a meeting in Barcelona, Spain, to discuss the use of biomarkers in the management of patients with bladder cancer. This meeting was the offspring of an - initially informal - group that finally resulted in the foundation and incorporation of the International Bladder Cancer Network (IBCN) e.V.

Enhanced normograms and pregnancy outcome analysis in nonhuman primate developmental toxicity studies.

The incidence of spontaneous pregnancy/infant losses is highly variable in long-tailed macaques (cynomolgus monkey), making it potentially difficult to ascertain test item-related effects in developmental toxicity studies. Therefore, pregnancy normograms had been developed by Jarvis et al. [1] to aid in the distinction of normal (e.

Testing Gait with Ankle-Foot Orthoses in Children with Cerebral Palsy by Using Functional Mixed-Effects Analysis of Variance.

Existing statistical methods extract insufficient information from 3-dimensional gait data, rendering clinical interpretation of impaired movement patterns sub-optimal. We propose an alternative approach based on functional data analysis that may be worthy of exploration. We apply this to gait data analysis using repeated-measurements data from children with cerebral palsy who had been prescribed fixed ankle-foot orthoses as an example.

Vapor Phase Exchange of Self-Assembled Monolayers for Engineering of Biofunctional Surfaces.

We show that 4'-nitro-1,1'-biphenyl-4-thiol self-assembled monolayers (NBPT SAMs) on gold can be exchanged with 11-(mercaptoundecyl)triethylene glycol (CEGOH) SAMs via vapor deposition (VD). The pristine and the exchanged SAMs obtained by VD as well as solution method (SM) were characterized by X-ray photoelectron spectroscopy (XPS) and polarization modulation infrared reflection-absorption spectroscopy (PM-IRRAS). Using surface plasmon resonance (SPR), it is shown that CEGOH SAMs on gold obtained by vapor deposition exchange (VD) have the same protein resistivity as SAMs obtained by the direct self-assembly process.

Dermatopathology in sub-Saharan Africa: a systematic 5-year analysis of all histopathological diagnoses from the Regional Dermatology Training Centre (RDTC) in Moshi, Tanzania.

Background: Proper diagnosis of skin diseases relies on dermatopathology, the most important diagnostic technique in dermatology. Unfortunately, there are few dermatopathology institutions in sub-Saharan Africa, where little is known about the spectrum of histopathological features observed.

Objectives: To investigate the spectrum of dermatopathological diagnoses made in a sub-Saharan African reference centre of a large, mainly rural area.

Initiation of antiretroviral therapy in HIV-infected adults with skin complaints in northern Tanzania.

Abnormal skin findings are identified in over 90% of human immunodeficiency virus (HIV)-infected persons globally. A prospective cohort study of HIV-infected patients with skin complaints commencing antiretroviral therapy (ART) in northern Tanzania was undertaken. Consecutive HIV-infected subjects presenting with skin complaints, who met criteria for ART initiation, were recruited at a Tanzanian Regional Dermatology Training Center.

Managing skin disease in resource-poor environments - the role of community-oriented training and control programs.

Programs that have been devised to improve the lot of patients with skin disease, or disease presenting with skin signs and symptoms, in resource-poor regions have focused mainly on education and training or community-oriented control measures. However, both have in common an objective of managing disease at population level. Training has been delivered in different ways both by direct teaching for varying periods of time or by web-based and electronic communication; control measures have been less in evidence and there is a great need for more support from funding agencies.

Protein resistant oligo(ethylene glycol) terminated self-assembled monolayers of thiols on gold by vapor deposition in vacuum.

Protein resistant oligo(ethylene glycol) (OEG) terminated self-assembled monolayers (SAMs) of thiols on gold are commonly used for suppression of nonspecific protein adsorption in biology and biotechnology. The standard preparation for these SAMs is the solution method (SM) that involves immersion of the gold surface in an OEG solution. Here the authors present the preparation of 11-(mercaptoundecyl)-triethylene glycol [HS(CH(2))(11)(OCH(2)CH(2))(3)OH] SAMs on gold surface by vapor deposition (VD) in vacuum.

Hearing impairment in Tanzanians with albinism.

Community-based studies have suggested that those affected with albinism, an important condition in East Africa, may be at a greater risk of developing hearing problems. This study shows that the prevalence of hearing loss is increased in Tanzanians with albinism and that hearing loss is associated with fewer years in education. 64 participants with albinism and 90 controls without were recruited from clinics held in the Western Kilimanjaro area.

Early detection and efficient therapy of cardiac angiosarcoma due to routine transesophageal echocardiography after cerebrovascular stroke.

Primary malignant cardiac tumors (cardiac angiosarcomas) are exceedingly rare. Since there are initially nonspecific or missing symptoms, these tumors are usually diagnosed only in an advanced, often incurable stage, after the large tumor mass elicits hemodynamic obstructive symptoms. A 59-year-old female presented with symptoms of cerebral ischemia.

Project RATEMA--one year's experience.

The RATEMA project is an international cooperation between the University of Ulm in Germany and the Urals Research Centre for Radiation Medicine in Chelyabinsk, Russia. For one year we conducted weekly conferences between the two sites, based on a satellite link with a 384 kbit/s connection. During the videoconferences the physicians on both sides--experts in radiation medicine--discussed the health status of Russian patients who had been chronically exposed to ionizing radiation in the South Urals region.

[The internet--its uses in traumatology].

No other words have obtained such meaning in the computer world as the catchwords "Online" and "Internet". The possibilities are innumerable, even in the medical field, and therefore we must consider whether trauma and orthopedic surgeons can also benefit from this new telecommunications medium. As a result of this inquiry, a pilot program has been initiated through an Internet connection at the computer center in the University of Ulm to test and define the possibilities of the Internet in routine clinical applications and for scientific projects.

Upregulation of gap junction protein connexin43 in alveolar epithelial cells of rats with radiation-induced pulmonary fibrosis.

The degree of immunoreactive connexin43 (C x 43) in rat lung was evaluated during the development of radiation-induced pulmonary fibrosis in rat by a double immunofluorescence technique using polyclonal antisera to Cx43 and monoclonal antibodies to cytokeratins on cryostat sections. In normal rat lungs, Cx43 was detected in pneumocytes type II and I, in large blood vessel endothelia, in peribronchial smooth muscle cells, and in some peribronchial and perivascular interstitial cells. As early as 1 week after irradiation, enhanced immunoreactivity for Cx43 in the epithelial cells was detected.

Tissue factor expression during human and mouse development.

In the adult organism the cellular distribution of tissue factor (TF) expression corresponds to biological boundary layers forming a hemostatic barrier ready to activate blood coagulation after tissue injury. Whether TF expression might also play a role in development is unknown. To determine the significance of TF in ontogenesis, we examined the pattern of TF expression in mouse development and compared it with the distribution of TF in human post-implantation embryos and fetuses of corresponding gestational age.

Detection of circulating tissue factor and factor VII in a normal population.

The plasma tissue factor (TF) concentration was correlated to factor VII concentration (FVIIag) and factor VII activity (FVIIc) in 498 healthy volunteers ranging in age from 17 to 64 years. Immunoassays using monoclonal antibodies (mAbs) were developed for the determination of TF and FVIIag in plasma. The mAbs and the test systems were characterized.

Immunohistochemistry of new type I alveolar epithelial cell markers of the rat.

The presence of pan-cadherin and the MEP-I antigen in normal and diseased rat lung was established by employing immunoperoxidase and double label fluorescence techniques. The binding of a mouse monoclonal antibody (MEP-1) reacting specifically with type I pneumocytes was assessed on paraffin sections of normal specimens as well as those with pulmonary fibrosis induced by bleomycin or radiation treatment. In injured alveolar epithelium, a diminished type I cell and a focal type II cell immunoreactivity was found.

Immunocytochemical distribution of E-cadherin in normal and injured lung tissue of the rat.

Affinity purified rabbit anti-mouse E-cadherin antibodies, reacting with diverse rat epithelia, were used to characterize epithelial changes in a radiation-induced fibrosis model of rat lung by immunoblotting techniques, immunoperoxidase and immunofluorescence microscopy. Immunostaining of normal rat lung tissues revealed a predominant staining of type II pneumocytes. Immunoelectron microscopy confirmed the immunohistochemical data of normal lung tissue obtained at the light microscopic level.

Monoclonal antibodies to surfactant protein D: evaluation of immunoreactivity in normal rat lung and in a radiation-induced fibrosis model.

This report describes the development of a new panel of monoclonal antibodies established after immunization of mice with purified surfactant protein D of the rat. To enhance the detection of SP-D in formalin- or Schaffer-fixed samples, immunohistochemistry was performed by using microwave pretreatment of paraffin sections. Using these new antibodies that bind to type II epithelial cells, Clara cells, and alveolar macrophages, the responses of lung parenchymal cells were examined in a radiation-induced fibrosis model.

Disseminated histoplasmosis in chronic mucocutaneous candidiasis.

Chronic mucocutaneous candidiasis (CMC) is rarely associated with disseminated Candida, but is often associated with systemic infection secondary to other organisms [1]. A 6-year-old with CMC and disseminated histoplasmosis is presented here.
