    This paper takes the form of a Brown Paper on the Coronavirus epidemic regarding the observed absence of Black and Latinx Doctors as media commentators, the disproportionately high death rates among members of these groups, and societal calls to address the cause of these enduring problems. This work attempts to explain the discrepancy involved through a hyper-quizzical and culturally sensitive exploration of anthropological, cultural, historical, societal, and other factors by using a multipronged and nonconventional approach. By exploring the manner in which racism possibly informs the problem, various mechanisms that inform success or failure in different Black and Latinx sub-groups were explored. They include (e.g., acting White or Black, individuals’ attitudes and perceptions, deficit thinking, child-rearing style, honorary Whites, immigration effect, model minority, parental involvement, racial grammar, and White privilege). The looming ascendancy of both groups to majority-minority population informs the urgency to confront the problem. Determination emerged that as the rising tides will lift all Americans’ boats, raising Blacks and Latinxs’ academic and technical competency will boost the nation’s capacity to compete in an increasingly globalized and high-tech world. It challenges the paradox related to Blacks and Latinxs’ boat of educational achievement remaining stationary, despite the many rising tides of educational reforms, laws, and massive expenditures. A “NEW NORMAL” fostering collaboration between Asians, Blacks from the diaspora, Latinxs, and progressive Whites is recommended to address the problem. Critically, the need to elevate medical professionals as STEM role models for Black and Latinx children, as opposed to current Black and Latino thespians (entertainment figures, sports stars, and rap artists) or gangsters, is also recommended.

  • Improving Learning Effectiveness- Some Aspects Shouldn’t Be Ignored in Mathematics Teaching

    There are abundant educational resources in the USA, but the performance of math education in primary and secondary schools is not so well, and has lagged behind some Asian countries including developing countries. Among many reasons, the crucial reasons are how teachers teach, how students learn, and the level of school teaching management. This paper focuses on how teachers teach in five aspects, particularly emphasizes on how to improve students’ retention and understanding of knowledge, and to enhance learning and thinking abilities. It points out that teachers should constantly remind students to maintain basic facts, create assignments for students by combining regular methods with the strategies of interleaved and spaced practice, build connections among knowledge, pay attention to improve students’ ability of problem-solving, and use some complementary approaches to generate students’ interest, participation, memory and concentration in math. And also it mentions that self-discipline, persistence and confidence are significant in prompting learning efficiency. In addition, some suggestions are put forward for school education management in supporting teaching and learning.

  • The Use of a Rapid Fluid Infusion System in Children

    Fluid resuscitation is the cornerstone of treatment for pediatric shock caused by conditions such as sepsis, dehydration, trauma, and anaphylaxis. Children presenting to the Emergency Department (ED) in shock have a high risk of mortality, and each hour of delay in shock reversal doubles the odds of death1,2. Pediatric Advanced Life Support (PALS) guidelines emphasize the importance of providing rapid fluid resuscitation to prevent the progression to hypotensive or refractory shock3. PALS and other septic shock guidelines recommend that patients receive a 20 mL/kg bolus of crystalloid immediately upon recognition of hypovolemic or distributive shock, with 20 mL/kg to be delivered within 5 minutes and up to 60 mL/kg within the first 15-60 minutes3-6. Studies based on these guidelines show that earlier fluid delivery directed at reversal of shock reversal leads to decreased morbidity7-9, mortality2,7,9-12, and hospital length of stay (LOS)9,11-13. Unfortunately, timely fluid delivery is often not achieved due to the technical challenges of obtaining adequate vascular access and delivering fluid boluses quickly in patients with shock or hypotension11,14-16. Current methods of fluid bolus delivery in the pediatric emergency care setting include infusion pumps, gravity drip, pressure bags, rapid infusers, and the push-pull syringe technique17,18. Each of these methods are limited by speed, ease of use, or safety concerns. Infusion pumps provide a maximum rate of 999 mL per hour, which for a 25kg child would provide a 60 mL/kg bolus in 90 minutes. In most patients, infusion pumps are therefore too slow to provide adequate fluid resuscitation. Gravity drip rates are unpredictable and inadequate for the treatment of shock and hypotension. For example, up to 50 minutes are required for one liter of fluid to flow through a 22G intravenous (IV) line, and up to 200 minutes via the intraosseous (IO) route19-22. A pressure cuff may speed flow…

  • Logical Beauty Harmony and Natural Shape zones (NSz)

    The concept of beauty in the world is certainly influenced by ethnicity and cultural factors, but generally harmony, balance and simmetry are common characteristics positively considered by every population. Logical Beauty Harmony is an innovative System for using filler and botulinum toxin in aesthetic medicine based on Natural Shape zones (NS zones). These compartment consist of strategic sequential injection areas that allow creating, improving or restoring adequate volumes, guaranteeing natural results and expressiveness. Starting from the recent acquisitions of Functional Anatomy, Physiology of Aging, Product Rheology and considering the objective analysis of the characteristics of harmony of each individual we have developed an approach that uses injectables in a targeted way using Support and Lifting vectors at the level of Upper, Middle and Lower Third of the face, injecting first deep and then passing to the surface. The face is divided into vertical and horizontal proportions. These simply but fundamental principle of facial proportion, modified by recent anthropometric studies, have found their way into the teaching and practice of cosmetic facial medicine and surgery. The series of data that can be detected by applying the previous parameters offers the chance of identify the variants that the face can present, so as to make eventually those changes that lead closer to the ideal model. In planning the treatment, the study of the different parameters, proportions, lines, ideal movements and angles linked to the comparison of the measurements of the different parts of the face will be more useful in determining type and extent of the corrections to be made. 9 treatment protocols for the face have been precisely established.

  • A rare case of Pleuroparenchymal fibroelastosis in Sri Lanka

    Pleuroparenchymal fibroelastosis (PPFE) is a very rare interstitial lung disease which carries many challenges in the process of diagnosis. A 73 years old female was evaluated for exertional dyspnea with CXR PA evidence of bilateral upper lobe fibrosis and pleural thickening. HRCT revealed typical features suggestive of PPFE. Lung biopsy was not performed considering the risk. Though it is rare PPFE should be considered when evaluating bilateral apical fibrosis. Proper radiological evaluation is paramount important in the process of diagnostic evaluation. Performance of lung biopsy as an essential criterion should be reconsider with associated risks.
