Social Media, Physical and Mental Health During a COVID-19 Lockdown
Social media including texting, internet use, and Facebook time have differential effects but those have not been studied during the social isolation of lockdowns when they might be more prevalent. In this Survey Monkey study, as many as 98% of 260 respondents reported texting, 100% using the internet, and 91% being on Facebook. The percentiles for those using the different media “a lot” were 45%, 77% and 42% respectively. Correlation analyses suggested that texting and internet use were positively related to Connecting Scale scores. However, internet use was also positively related to scores on Stress, Anxiety and Depression Scales and Facebook use was positively related to not only scores on Stress, Anxiety and Depression Scales but also to scores on Fatigue, Sleep Disturbance and PTSD scales. ANOVAS based on comparisons between groups reporting no to moderate use versus “a lot” of use were confirmatory of the correlation analyses. These results are limited by their being self-reported data from a non-representative, cross-sectional sample. Nonetheless, they highlight the positive and negative effects of different social media during a COVID-19 lockdown

Social Interaction and Social Media At Airport Departure Gates
An observational study was conducted at airline departure gates in several U.S. and European countries. Thirty-second observations were randomly made of 1360 different individuals ranging in age from infants to the elderly, although 79% of the travelers were adults. Most of the individuals were traveling with someone, except for adults who were more often traveling alone (58% vs. 42% time). Of the different types of social interaction and social media observed, cell phone texting/scrolling was significantly more frequently observed (at 53% time) than cell phone talking (13 % time), face-to-face interaction (13% time), on computer (7%) and touching (4%) which was the least frequently observed behavior. Significantly more cell phone texting/scrolling time occurred when adults were traveling alone (58% time). These data suggest that airline travelers are spending significantly more airport departure gate time on social media (specifically cell phone texting/scrolling) than face-to-face interaction or touching. Unfortunately, the observations that were made by professors and students were from too great a distance (10 feet away) in order to be unobtrusive but unable to code the precise type of cell phone texting/scrolling that was occurring

Massage Therapy Research Review
This narrative review on massage therapy effects involved a literature search for research that was published in the years 2016-2020. The review includes studies on massage therapy effects on preterm pain and growth, newborn hyperbilirubinemia and infant colic. The pediatric literature includes studies on behavior problems including ADHD and aggression and physical conditions including diarrhea, asthma, immune function and pain. The adult studies include massage therapy effects on psychological problems including stress and anxiety and physical conditions including fatigue, sleep disturbances, post-burn scarring, gastrointestinal problems and dementia. The musculoskeletal studies are focused on range of motion, balance, muscle activity, grip strength and performance recovery. The massage for pain literature is the most extensive including pain associated with labor, cesarean delivery, shoulder, neck, low back and upper back pain, arthritis, fibromyalgia, multiple sclerosis, cancer, neuropathy, post-surgery, hospice and aging. The physiological/biochemical measures that have been used include systolic and diastolic blood pressure, heart rate, vagal activity, facial blood flow, EEG, cortisol and oxytocin. This section is followed by a discussion on potential underlying mechanisms and methodological limitations. The research continues to have methodological limitations including that the studies cannot be double blinded, they are typically not multivariate studies and they are often biased by their reliance on self-report. Nonetheless, the randomized controlled trials included here as well as systematic reviews and meta-analyses have concluded that massage therapy is typically effective when it is compared to treatment as usual control groups, More research is needed on massage therapy versus active control groups (e.g. exercise and physical therapy) in randomized, controlled trials

Care for the Critically Injured Burn Patient Modulation of Burn Scars Through Laser Assisted Delivery of Stem Cells
The purpose of this study is to test the hypothesis that hypertrophic burn scars can be remodeled by fractional laser treatment andadministration of stem cells. Finding the best ways to combine these approaches is a goal of this proposal. During the period of this reportwe have been completing an examination of the effect of administering autologous and allogeneic bone marrow derived mesechymal stem cells (BM-MSCs) and adipose derived stem cells (ADSC) to hypertrophic third degree burn scars in Red Duroc pigs using ablative fractional CO2 or Erbium:YAG lasers. Epidermal and superficial dermal remodeling was noted to varying degrees in specimens treated with BM-MSCs and ADSCs by both lasers. Further Western blot, cell culture and Real Time PCR analysis along with additional studies performed on uninjured skin have indicated that: i) CO2 laser can have a more tissue damaging effect than Erbium:YAG laser, ii) autologous stem cells appear to generate a less fibrotic response, iii) cells derived from autologous stem cell treated burns have a more immature phenotype, iv) collagen indicative of dermal remodeling may be more persistent when burns are treated with autologous BM-MSCs, and v) cells derived from stem cell treated burns appear to peak 14 Days after treatment and taper significantly beyond 21 Days after treatment. Overall, these findings indicate that Erbium:YAG and perhaps autologous stem cells may have and advantage in treating hypertrophic burn scars. They also suggest that repeat administration is likely to be beneficial, again favoring the use of autologous cells

NONLINEAR DYNAMICS IN TUMOR-IMMUNE SYSTEM INTERACTION MODELS WITH DELAYS
In this paper, we review some recent results on the nonlinear dynamics of delayed differential equation models describing the interaction between tumor cells and effector cells of the immune system, in which the delays represent times necessary for molecule production, proliferation, differentiation of cells, transport, etc. First we consider a tumor-immune system interaction model with a single delay and present results on the existence and local stability of equilibria as well as the existence of Hopf bifurcation in the model when the delay varies. Second we investigate a tumor-immune system interaction model with two delays and show that the model undergoes various possible bifurcations including Hopf, Bautin, Fold-Hopf (zero-Hopf), and Hopf-Hopf bifurcations. Finally we discuss a tumor-immune system interaction model with three delays and demonstrate that the model exhibits more complex behaviors including chaos. Numerical simulations are provided to illustrate the nonlinear dynamics of the delayed tumor-immune system interaction models. More interesting issues and questions on modeling and analyzing tumor-immune dynamics are given in the discussion section
