Background Telemedicine was implemented in Brazil as a way to support primary health care (PHC). see more Orthopedic complaints are common in PHC, and, because musculoskeletal diseases are the most frequent causes of chronic pain, it is important to explore knowledge gaps of PHC as well as to understand the teleconsultations' impact on reducing referrals to secondary care. Materials and Methods Observational, retrospective study that analyzed consecutive orthopedic asynchronous teleconsultations from the Telehealth Network of Minas Gerais, a large-scale public telehealth service, performed from September 17, 2013 to June 18, 2020. Teleconsultations were analyzed based on the type of query. Results Throughout the study, 1,174 teleconsultations from 254 municipalities were analyzed. Most requests for teleconsultations were from nurses (37.8%) and physicians (48.7%). In 58.3%, challenges could be solved by a general practitioner, meanwhile 38.4% needed referral to an orthopedic specialist. Most queries related to a specific case (assistencial teleconsultation, 66.0%), and the others were classified as educational (34%). With regard to the motivation for the assistencial teleconsultations, 72% approached treatment options, 49.5% surrounded possible diagnosis, and 20.1% discussed patient's rehabilitation. In addition, 95.5% of requests could be solved by teleconsultation, without the need for referral to in-person consultation with the specialist. Conclusions Teleconsultations can help investigate the most frequent queries in PHC. Most of them were solved without the need for referral, showing the potential of teleconsultations in daily practice as a way to manage patients and guarantee better access to first-rate health care. As for the public health system, teleconsultations represent a way to overcome the distance barrier to health care access.Leopard attacks on human beings is common in Uttarakhand which is an area of national conservation. The objective of this study is to examine the pattern of injuries and circumstances to encourage ways of reducing such conflicts. There were eight deaths from leopard attacks brought for autopsy to the mortuary between January 2019 and August 2020. Incidents occurred mostly in a forest close to human settlements. One tourist was among the male victims, the remainder of whom were women carrying out household duties near the forest. Leopard attack injuries present in the head and neck were ante-mortem, with abdomen, buttocks and limbs post-mortem. People living at the border of protected areas need alternative means of support to enable them to avoid using forest resources, tourists must be warned to avoid wandering in the area.Background Patients (≥60 years) with acute myeloid leukemia (AML) often receive intense health care utilization at the end of life (EOL). However, factors associated with their health care use at the EOL are unknown. Methods We conducted a secondary analysis of 168 deceased patients with AML within the United States. We assessed quality of life (QOL) (Functional-Assessment-Cancer-Therapy-Leukemia), and psychological distress (Hospital-Anxiety-and-Depression Scale [HADS]; Patient-Health-Questionnaire-9 [PHQ-9]) at diagnosis. We used multivariable logistic regression models to examine the association between patient-reported factors and the following outcomes (1) hospitalizations in the last 7 days of life, (2) receipt of chemotherapy in the last 30 days of life, and (3) hospice utilization. Results About 66.7% (110/165) were hospitalized in the last 7 days of life, 51.8% (71/137) received chemotherapy in the last 30 days of life, and 40.7% (70/168) utilized hospice. In multivariable models, higher education (odds ratio [OR] = 1.54, p = 0.006) and elevated baseline depression symptoms (PHQ-9 OR = 1.09, p = 0.028) were associated with higher odds of hospitalization in the last seven days of life, while higher baseline QOL (OR = 0.98, p = 0.009) was associated with lower odds of hospitalization at the EOL. Higher baseline depression symptoms were associated with receipt of chemotherapy at the EOL (HADS-Depression OR = 1.10, p = 0.042). Higher education was associated with lower hospice utilization (OR = 0.356, p = 0.024). Conclusions Patients with AML who are more educated, with higher baseline depression symptoms and lower QOL, were more likely to experience high health care utilization at the EOL. These populations may benefit from interventions to optimize the quality of their EOL care.Carbon "quantum" dots or carbon dots (CDots) exploit and enhance the intrinsic photoexcited state properties and processes of small carbon nanoparticles via effective nanoparticle surface passivation by chemical functionalization with organic species. The optical properties and photoinduced redox characteristics of CDots are competitive to those of established conventional semiconductor quantum dots and also fullerenes and other carbon nanomaterials. Highlighted here are major advances in the exploration of CDots for their serving as high-performance yet nontoxic fluorescence probes for one- and multi-photon bioimaging in vitro and in vivo, and for their uniquely potent antimicrobial function to inactivate effectively and efficiently some of the toughest bacterial pathogens and viruses under visible/natural or ambient light conditions. Opportunities and challenges in the further development of the CDots platform and related technologies are discussed.Objective The coronavirus disease 2019 (COVID-19) pandemic forced many clinicians to rapidly adopt changes in their practice. In this study, we compared patterns of utilization of Ontario eConsult before and after the onset of the COVID-19 pandemic, to assess COVID 19's impact on how eConsult is used. Materials and Methods We conducted a longitudinal analysis of registration and utilization data for Ontario eConsult. All primary care providers (PCPs) and specialists who joined the service between March 2019 and November 2020, and all eConsult cases closed during the same period were included. The data were divided into two timeframes for comparison prepandemic (March 2019-February 2020) and pandemic (March 2020-November 2020). Results In total, 5,925 PCPs joined during the study period, more than doubling total enrollment to 11,397. The average monthly number of eConsults increased from 2,405 (standard deviation [SD] = 260) prepandemic to 3,906 (SD = 420) pandemic. Case volume jumped to 24.3% in the first month of the pandemic, and increased by 71% during the COVID-19 pandemic timeframe. The median response time was similar in both timeframes (prepandemic 1.0 days; pandemic 0.9 days). The proportion of cases resulting in new/additional information (prepandemic 55%, pandemic 57%) or avoidance of a contemplated referral (prepandemic 52%, pandemic 51%) remained consistent between timeframes. Conclusions Registration to and usage of eConsult increased during the pandemic. Metrics of the service's impact, including response time, percentage of cases resulting in new or additional information, and avoidance of originally contemplated referrals were all consistent between the prepandemic and COVID-19 pandemic timeframes, suggesting scalability.Biliary fibrosis is an important pathological indicator of hepatobiliary damage. Cholangiocyte is the key cell type involved in this process. To reveal the pathogenesis of biliary fibrosis, it is essential to understand the normal development as well as the aberrant generation and proliferation of cholangiocytes. Numerous reports suggest that the Wnt signaling pathway is implicated in the physiological and pathological processes of cholangiocyte development and ductular reaction. In this review, we summarize the effects of Wnt pathway in cholangiocyte development from embryonic stem cells, as well as the underlying mechanisms of cholangiocyte responses to adult ductal damage. Wnt signaling pathway is regulated in a step-wise manner during each of the liver differentiation stages from embryonic stem cells to functional mature cholangiocytes. With the modulation of Wnt pathway, cholangiocytes can also be generated from adult liver progenitor cells and mature hepatocytes to repair liver damage. Non-canonical Wnt signaling is triggered in the active ductal cells during biliary fibrosis. Targeted control of the Wnt signaling may hold the great potential to reduce and/or reverse the biliary fibrogenic process.There are growing calls to broaden palliative care access to more populations, diseases, and care settings and to earlier in the disease process; yet, supply of specialty palliative care is not likely to keep pace with demand. This article discusses possible solutions by which to bridge the gap between limited palliative care supply and demand. The proposed solutions include (1) specialist workforce development; (2) alternate models of care; (3) triaging systems; and (4) telemedicine. Education/training, research, and policy mechanisms could operationalize these solutions. With the solutions in hand, the field may be able to increase the reach, sustainability, and equity of palliative care, thereby improving access and enabling a multitude of positive patient, family, and health care system outcomes.Background Brow-lift-induced eyelid closure impairment is commonly discussed in patients with facial paralysis but has not been well quantified. Objective To measure the limitation of eyelid closure in patients with facial paralysis using simulated brow-lift with tape. Design, Setting, and Participants For 50 facial paralysis patients with brow ptosis who visited our institution from October 2017 to December 2020, brow-lift was simulated by elevating the paralyzed-side brow using surgical tape, and closed palpebral fissure heights in spontaneous blinking were measured using high-speed videography. The effect of several factors on the change in closed palpebral fissure height was evaluated by multiple linear regression analysis. Results Greater patient age (p = 0.021), single eyelids (p = 0.003), higher value of closed palpebral fissure height before simulation (p = 0.004), and higher value of brow elevation (p = 0.013) were significant for the increase of closed palpebral fissure height. Conclusions Brow elevation to the degree that achieves symmetrical brow height could be detrimental to eyelid closure in patients with facial paralysis, especially who are elderly, have single eyelids, or present with preoperative decreased lid-closure function.

We propose an elegant route to obtain TTC-bCP starting from 2,2'-azobis(2-methylpropionitrile) (AIBN) as a donor of the 2-cyanopropan-2-yl group. TTC-bCP allowed the preparation of a high-molar-mass (Mn ≈ 135 kg mol-1) methyl methacrylate-n-butyl acrylate-methyl methacrylate triblock copolymer with unprecedented control (D̵ = 1.04) in reversible-deactivation radical polymerization. Rheology measurements of this triblock copolymer showed a typical thermoplastic elastomer behavior with a steady rubbery plateau up to 120 °C.
