Projecting Quarantine Utilization During a Pandemic
Authors: Li Wenrui , Kolaczyk Eric D. , White Laura F. 
Published: January 2022

Objectives. To develop an approach to project quarantine needs during an outbreak, particularly for communally housed individuals who interact with outside individuals. Methods. We developed a method that uses basic surveillance data to do short-term projections of future quarantine needs. The development of this method was rigorous, but it is conceptually simple and easy to implement and allows one to anticipate potential superspreading events. We demonstrate how this method can be used with data from the fall 2020 semester of a large urban university in Boston, Massachusetts, that provided quarantine housing for students living on campus in response to the COVID-19 pandemic. Our approach accounted for potentially infectious interactions between individuals living in university housing and those who did not. Results. Our approach was able to accurately project 10-day-ahead quarantine utilization for on-campus students in a large urban university. Our projections were most accurate when we anticipated weekend superspreading events around holidays. Conclusions. We provide an easy-to-use software tool to project quarantine utilization for institutions that can account for mixing with outside populations. This software tool has potential application for universities, corrections facilities, and the military. (Am J Public Health. 2022;112(2):277–283. https://doi.org/10.2105/AJPH.2021.306573 )
Science Translation During the COVID-19 Pandemic: An Academic-Public Health Partnership to Assess Capacity Limits in California
Authors: Maldonado Peter , Peng Angie , Ouyang Derek , Suckale Jenny , Ho Daniel E. 
Published: January 2022

On the basis of an extensive academic–public health partnership around COVID-19 response, we illustrate the challenge of science-policy translation by examining one of the most common nonpharmaceutical interventions: capacity limits. We study the implementation of a 20% capacity limit in retail facilities in the California Bay Area. Through a difference-in-differences analysis, we show that the intervention caused no material reduction in visits, using the same large-scale mobile device data on human movements (mobility data) originally used in the academic literature to support such limits. We show that the lack of effectiveness stems from a mismatch between the academic metric of capacity relative to peak visits and the policy metric of capacity relative to building code. The disconnect in metrics is amplified by mobility data losing predictive power after the early months of the pandemic, weakening the policy relevance of mobility-based interventions. Nonetheless, the data suggest that a better-grounded rationale for capacity limits is to reduce risk specifically during peak hours. To enhance the connection between science, policy, and public health in future times of crisis, we spell out 3 strategies: living models, coproduction, and shared metrics.

Published: January 2022

Objectives. To assess the popularity of an emergent drug, delta-8 tetrahydrocannabinol (THC), and compare interest levels between US states with or without legalized recreational cannabis. Methods. We used Google Trends to assess the growth of interest among delta-8 THC–related search terms from May 17, 2020, to May 9, 2021. We examined differences between states with or without legalized cannabis using state-level Google Trends data from February 13 to May 13, 2021, and policy data from the National Conference of State Legislatures. Results. Interest in delta-8 THC increased starting in mid-June 2020, with search volumes for delta-8 THC queries currently at 35% of the “marijuana” query. States where recreational cannabis is illegal had higher relative queries than did states with legalized recreational cannabis (52.3 vs 14.8; t = 40.9; P < .001). Conclusions. There has been rapid growth in interest in delta-8 THC. Findings between state policy contexts likely indicate delta-8 THC’s role as a substitute good for delta-9 THC. Public Health Implications. Digital signals such as search volumes may point to an emergent use trend in the substance delta-8 THC. Further studies are needed to assess potential harms and correlates of delta-8 THC use.

Multidisciplinary Approach to Multiple Multiresistant Agent Infection of Instrumented Spine Surgery
Authors: Xará-Leite Francisco , Ribau Ana , Lopes Guerra Mário Diogo , Abreu Miguel Araújo , Rodrigues-Pinto Ricardo 
Published: January 2022

Case:
We report the case of a patient with consecutive infections with several multidrug-resistant agents—including carbapenem-resistant strains of Klebsiella pneumoniae among others—from a surgical wound infection after lumbar spine fusion, only successfully treated after the resort to novel antibiotics (ceftazidime-avibactam) in combination therapy.

Conclusions:
Multidrug resistance has become a major challenge in today’s medicine. Care should be taken to avoid their emergence, but when present, a multidisciplinary approach is mandatory to ensure clinically up-to-date treatment choices. Multimodal antibiotic schemes tend to show the most promising results, with which successful infection resolution can still be achieved.

Abstract
Background: Numerous instruments to evaluate the functional independence and disability are available for healthcare professionals, making it difficult for patients and their families to evaluate and explain the results. Longshi Scale is the first pictorial-based disability assessment tool and it may allow a much simply and inclusive assessment across all population. The objective of this study was to test the reliability of the Longshi Scale for informal caregivers to assess functional independence and disability. Methods: This study was conducted at the inpatient rehabilitation departments from 24 hospitals in 11 cities across China. The patients who were more than 18 years old and diagnosed with cerebral infarction, cerebral hemorrhage, brain trauma, spinal cord injury, postoperative brain tumors, and other disorders causing physical functional disabilities were recruited. Then the Longshi Scale was used to assess the functional independence and disability of patients by both healthcare professionals and informal caregivers. Descriptive statistics (i.e., frequency, percentage, mean, and standard deviation) were calculated. The Kolmogorov-Smirnov test was used to examine the normal distribution of the data. The chi-square test or McNemar-Bowker test was used to compare the nominal variables of the three groups. T‑tests were used to compare the mean of the quantitative variables of the two groups. The agreement between the scores was assessed using Cohen’s kappa statistic and the marginal homogeneity test. Results: In total of 947 patients were included. Of these, 419 were in the “bedridden group”, 298 in the “domestic group”, and 230 in the “community group”. The mean scores were 5.00±1.936, 5.37±1.656 and 7.18±2.055 in the bedridden, domestic, and community groups, respectively. The mean score of each item was compared, and there were no significant differences between healthcare professionals and informal caregivers (p > 0.05). The Longshi Scale items and the sum score had fair or better agreement (weighted kappa > 0.50) between healthcare professionals and informal caregivers’ scores. The reliability of Longshi Scale was found to be acceptable.Conclusions: This study demonstrated fair or better agreement between healthcare professionals’ and informal caregivers’ scores on Longshi Scale items and their sum scores. The Longshi Scale for the assessment of the functional independence and disability by informal caregivers, is reliable.Trail registration: ChiCTR2000040556.

Published: January 2022

Abstract
Purpose

Multiple studies on salvage surgery (SS) implied the efficacy but the estimate of quality of life (QOL) after SS was poorly analyzed. Our study aimed to examine the quality of life before and after salvage surgery using the validated instruments QLQ-H&N35 and UW-QOL and investigate the value of salvage surgery by quantifying survival outcomes.
Materials and methods

Among 21 patients, preoperative and postoperative QOL were accessed using QLQ-H&N35 and UW-QOL questionnaire. Patients’ demographic characteristics, history of treatment, recurrent tumor characteristics, salvage surgery details and follow-up date were abstracted from our prospective database. Statistical analysis methods included Wilcoxon signed-rank test, descriptive analysis and Kaplan-Meier method.
Results

The overall quality of life was significantly improved after salvage surgery. Pain was significantly relieved whilst diminished functions were hinted with significant differences in UW-QOL domains swallowing, chewing, speech, shoulder, taste, saliva and in QLQ-H&N35 domains swallowing, speech, social eating, senses, dry mouth, sticky saliva as p༜0.05. The median disease-free survival of whole 21 patients was 5 months (range 0-73) and the median overall survival was 13 months (range 1-73).
Conclusions

The quality of life after salvage surgery for extensively recurrent head and neck cancer is acceptable. Despite the dysfunctions such as dysphagia and dry mouth, it does relieve the pain and improve the short-term overall QOL of patients. Further studies on quality of life before and after salvage surgery in HNSCC are obviously needed. In the future, postoperative functional recovery training also needs attention during follow up.

Abstract
COVID-19 results in increased expression of inflammatory cytokines, but inflammation-targeting clinical trials have yielded poor to mixed results. Our studies of other disorders with an inflammatory component, including Alzheimer’s disease, chemobrain, Down syndrome, normal aging, and West Nile Virus infection, showed that treatment with the ‘pro-inflammatory’ cytokine granulocyte-macrophage colony stimulating factor (GM-CSF) in humans or mouse models alleviated clinical, behavioral, and pathological features. We proposed that human recombinant GM-CSF (sargramostim) be repurposed to promote both the innate and adaptive immune responses in COVID-19 to reduce viral load and mortality1. Here, we report the results of a placebo-controlled study of GM-CSF in human ACE2 transgenic mice inoculated intranasally with SARS-CoV2 virus, a model of COVID-19. Infection resulted in high viral titers in lungs and brains and over 85% mortality. GM-CSF treatment beginning one day after infection increased anti-viral antibody titers, lowered mean lung viral titers proportionately (p=0.0020) and increased the odds of long-term survival by up to 5.8-fold (p=0.0358), compared to placebo. These findings suggest that, as an activator of both the innate and adaptive immune systems, GM-CSF/sargramostim may be an effective COVID-19 therapy with the potential to protect from re-infection more effectively than treatment with antiviral drugs or monoclonal antibodies.

Abstract
Neuroblastoma (NB) is a malignant pediatric tumor requiring new treatments. Accumulating evidence has confirmed that microRNAs (miRNAs) have a major effect on NB metastasis. The present study aimed to characterize a novel miRNA, miR-32-5p, by exploring its expression, function, as well as action mechanism in NB metastasis. Real-time quantitative polymerase chain reaction (qRT-PCR) as well as Western blotting was utilized to measure the expression of miR-32-5p and its target-vacuolar protein sorting 4B (VPS4B). Transwell assay was conducted to test the cell migration as well as its invasion in vitro, and the metastasis xenograft model of nude mice was set up by injections through the caudal vein in vivo. In comparison with the normal tissue and cell line, the miR-32-5p expression showed a marked downregulation in human NB samples and cell lines. Furthermore, the miR-32-5p upregulation suppressed NB cell metastasis in culture and the tumor xenograft model. Although in NB cell lines, VPS4B was found to be miR-32-5p’s direct target, its overexpression would reverse miR-32-5p’s suppressive effects. Moreover, miR-32-5p increased the sensitivity to dihydroartemisinin in neuroblastoma. The current outcomes implicated that the axis of miR-32-5p/VPS4B can be NB metastasis’s novel therapeutic target.

Published: January 2022

Abstract
Purpose TiO2 recovered from spent SCR catalyst, a hazardous industrial solid waste, was modified by g-C3N4 to produce the recovered TiO2 (R-TiO2) /g-C3N4 photocatalyst to protect valuable Ti resources and revamp its shortage of underutilization of visible light. Methods The R-TiO2 which was obtained from spent SCR catalyst by alkali leaching method was used to prepare the R-TiO2/g-C3N4 photocatalyst via self-assembly procedure. The photodegradation efficiencies of the prepared samples were evaluated by degradation of Rhodamine B (RhB) under visible light.Results The XRD patterns indicate that R-TiO2 remains the crystal structure of standard anatase TiO2 phase intact all along in recovery process. The photodegradation efficiency of the R-TiO2/g-C3N4 photocatalyst evaluated by degradation of RhB under visible light optimally reached 97.11% when the system was irradiated for only 40 min. For comparison, the best RhB degradation rate constant from the R-TiO2/g-C3N4 photocatalyst was about 1.9 times that of the pure TiO2/g-C3N4 photocatalyst. Conclusion The results demonstrate that the TiO2/g-C3N4 photocatalyst with recovered TiO2 from spent SCR catalyst show excellent photodegradation efficiency for RhB. Moreover, the RhB degradation efficiency over the R-TiO2/g-C3N4 photocatalysts are superior to pure TiO2/g-C3N4 photocatalysts.
