Pneumothorax in COVID-19 Acute Respiratory Distress Syndrome: Case Series

Objective The study aims to describe the clinical characteristics and outcomes of patients with COVID-19 related acute respiratory distress syndrome (ARDS) who developed pneumothorax. Design and setting A retrospective chart review was performed of the electronic medical record. Patients were included if they were identified as having confirmed COVID-19 as well as pneumothorax from March 16, 2020 to May 31, 2020. Patients' demographic and clinical characteristics, mechanical ventilator parameters, lung compliance measurements and outcomes during hospitalization were collected. This case series was conducted in intensive care units at two large tertiary care centers within the Northwell Health System, located in New York State. Patients A total of 75 patients were identified who were predominantly male (73.3%) with an average age of 62.8 years. Thirty (40%) were Hispanic, 20 (26.7%) were White, 16 (21.3%) were Asian, and nine (12%) were Black. Common comorbid conditions were hypertension (52%), diabetes mellitus (26.7%), hyperlipidemia (32.0%), and chronic pulmonary disease (8, 10.7%). Measurements and main results Most of the patients were diagnosed with pneumothorax while on mechanical ventilation (92%) despite overall adherence with lung-protective ventilation strategies. Average tidal volume was 6.66 mL/kg) of ideal body weight. The average positive end-expiratory pressure (PEEP) was 10.83 (cm) H2O. Lung compliance was poor, with average peak and plateau pressures of 41.9 cm H2O and 35.2 cm H2O, respectively. Inpatient mortality was high in these patients (76%). Conservative management with initial observation had a success rate (73.3%) with similar mortality and shorter length of stay (LOS) on average. Significant factors in the conservatively managed group included lack of tension physiology, the smaller size of pneumothorax, lack of underlying diabetes, presence of pneumomediastinum, and not being on mechanical ventilation during diagnosis. Conclusion Despite overall adherence to best practice ventilator management in ARDS, we observed a large number of pneumothoraces during the COVID-19 pandemic. Conservative management may be appropriate if there are no clinical signs or symptoms of tension physiology and pneumothorax size is small.
Solvent screening study and conceptual extractive distillation process to produce anhydrous ethanol from fermentation broth

This solvent screening study indicates that glycols are very selective solvents for producing anhydrous ethanol from fermentation broth by extractive distillation. The promising solvents are glycerin, ethylene glycol, tetraethylene glycol, and triethylene glycol. An improved extractive distillation process for producing anhydrous ethanol was conceptually developed which was based on the analysis of the experimental solvent screening data. The basic idea of this process is to add an extractive solvent only to the ethanol-rich portion of the fractionator to eliminate the ethanol-water azeotrope and to change the undesirable shape of the vapor-liquid equilibrium curve to one more favorable for distillation. With a suitable solvent, such as ethylene glycol, anhydrous ethanol could be produced from the fermentation broth in a column with only 18 theoretical trays. A low reflux ratio of 1.5 and a low solvent-to-feed ratio of 0.27 (based on fermentation broth) would be needed for the separation.

Suspicious minds: The psychological, physical and behavioral consequences of suspecting a partner’s infidelity

Guided by transactional stress theory, this study examined the psychological, physical, and behavioral consequences of the suspicion of a partner’s infidelity. Survey data collected from 246 individuals revealed that suspecting a partner’s infidelity was associated with greater reported suspicion-related distress, depression, physical health symptoms, and risky health behavior. Mediation and moderated mediation analyses revealed that the relationship between suspected infidelity and well-being was indirectly affected by suspicion-related distress. The effects of suspected infidelity were particularly hard on those with higher beliefs in the importance of fidelity, a history of infidelity in the relationship, and higher relationship satisfaction. The findings show that the mere suspicion of a partner’s infidelity can have powerful psychological, physical, and behavioral consequences in romantic relationships.
Economic Development Effects of Major and Minor League Teams and Stadiums

Professional teams and leagues claim new stadiums lead to economic development. To test this, we utilize data from the Census Bureau on net establishment and employment changes across 871 Metropolitan and Micropolitan Statistical Areas from 2004 to 2012. Difference-in-differences and panel data techniques allow for a cross-sectional and time series comparison for both teams and new stadia in both professional and development leagues. Nearly all results from hundreds of models are insignificantly different from zero. Results from between- and random-effects models suggest that teams move into markets that already have higher employment and establishment growth. (JEL R58, H71, L83, Z28)

Posttraumatic Growth in the Context of Grief: Testing the Mindfulness-to-Meaning Theory

Abstract In the context of traumatic grief, mindfulness might facilitate posttraumatic growth (PTG). The cognitive processes by which trait mindfulness predicts PTG, and for whom this pathway is most relevant, remains unclear. We tested the Mindfulness-to-Meaning Theory of grief in a cross-sectional study of mindfulness, meaning-making, and PTG among those who had lost a loved one. Mindfulness most strongly predicted higher PTG for individuals high in traumatic grief. Meaning-making mediated the effect of mindfulness on PTG most strongly for those low-to-average in traumatic grief. Results suggest meaning-making as a pathway, but may not explain the mindfulness-PTG link in more traumatized individuals.
Efficacy and safety of amantadine as a treatment for apathy after brain injury: Two single-case experimental design studies

ABSTRACT Studies on the efficacy of amantadine as a treatment for apathy after brain injury are scarce and of low quality. We examined the efficacy and safety of amantadine for treatment of apathy in two individuals with brain injury. Two double-blind, randomized, single-case experimental (baseline-amantadine-placebo-withdrawal) design (SCED) studies. Apathy measures included a Visual Analogue Scale (VAS), the Neuropsychiatric Inventory (NPI) apathy subscale and the Behavior Rating Inventory of Executive Function for Adults “Initiate” subscale. Safety measures included a rating scale of possible side effects of amantadine and physical examinations. No difference in apathy symptoms (VAS) between baseline and amantadine phase was found in case 1 (NAP = 0.55). Surprisingly, in case 2, apathy symptoms deteriorated from baseline to amantadine phase (NAP = 0.28, 90% CI = −0.69 to −0.20) and improved from amantadine to placebo phase (NAP = 0.92, 90% CI = 0.60–1.00). This improvement was also found on the NPI apathy subscale. Side effects of amantadine were observed in case 2. In this SCED study, amantadine did not improve apathy symptoms in two individuals with brain injury. However, this study shows that side effects of amantadine can occur which lead to a significant decrease in well-being. More high quality studies are required.
Physico-chemical characteristics of the soils in three church forest of central Ethiopia

Physical and chemical properties of soils interact each other either positively or negatively depending on the condition. Vegetation has influence on the soil physico-chemical characteristics. Land use land cover changes are the main factors in the process of land resource degradation. The objectives of this study were to define the soil texture, bulk density and extent of organic carbon in church forests and adjacent croplands and to compare the values. Transect lines of 100 apart and plots of 20mx20m were established to collect soil samples in the church forests and individual farm plots. The distance between plots was 100m. Horizon based soil sampling was undertaken. Soil samples were collected on a diagonal position from 2 edges and the center from 2 soil horizons (H1 and H2) for soil texture and soil organic carbon (SOC) analysis. For bulk density (BD) soil core samplers were used. The data was analyzed using one way ANOVA in SPSS v20. Mean separation was undertaken by LSD. The results revealed the %clay content was significantly higher in croplands than church forests and the %sand was higher in church forests than croplands at (p<0.05). The SOC was significantly higher in H1 than H2 and in church forests than croplands at (p<0.05). The better soil characteristics were obtained in church forests than in croplands. Hence, it is recommended to conserve the natural forests as in the church forests to maintain better property of the soil through enhancing SOM, SOC and by decreasing soil BD.
The Differential Relationship between Self-Control and Peer Influences over Time: Toward an Integrative Model of Offending Using a Dual-Systems Approach

The purpose of this study is to explore an alternative approach to unravel how both self-control and peer influence relate to offending. Deriving from a dual-systems framework, this study hypothesizes that individuals with varying levels of self-control will be differentially susceptible to the effects of both exposure to deviant peers and informal socializing with peers. Analyses are based on a sample of serious youthful offenders from the Pathways to Desistance Study. The results indicate that exposure to deviant peers has a stronger impact on offending for individuals with higher self-control, consistent with the hypothesis. However, individuals with higher self-control are more vulnerable to unstructured and unsupervised socializing with peers than those lower in self-control, which counters the hypothesis.
Layered silicate clay functionalized with amino acids: wound healing application

Natural materials such as “healing clays” in mud spas have been used for healing of skin ailments and wounds since prehistoric times. In this study, laponite, a synthetic clay mineral with similar properties to natural healing clays has been functionalized with different amino acids for the purpose of wound dressing application. Physico-chemical properties of prepared laponite/amino acid gels were characterised using various analytical methods. X-ray diffraction and thermogravimetric analysis confirmed the presence of these amino acids in the prepared materials. The release profile of amino acid in simulated wound exudate fluid demonstrated the highest release from laponite/lysine groups with up to 50% of the intercalated lysine released. The effect of the extracts (obtained from the prepared laponite/amino acid gels) was tested on human skin fibroblast. Cell proliferation, oxidative stress, anti-oxidant properties, and in vitro wound healing (scratch assay model) were assessed. The extracts obtained from laponite alone and laponite combined with arginine, lysine and leucine promoted fibroblast proliferation whereas the extract from laponite/glutamic acid significantly inhibited cell proliferation. Based on the in vitro results presented in this work, laponite/arginine, laponite/leucine and laponite/lysine can be potentially applied as a wound dressing to promote the healing process.
Obesity Impacts Mortality and Rate of Revascularizations Among Patients With Acute Myocardial Infarction: An Analysis of the National Inpatient Sample

Background Obesity is now a recognized chronic comorbid condition which is highly prevalent in the United States. Obesity poses several health risks, affecting multiple organ systems. The cardiovascular system is particularly affected by obesity including its role in atherosclerotic disease and hence myocardial infarction (MI) from atheromatous plaque events. However, multiple population-based studies have shown mixed outcomes in obese patients who have acute MI. This study aimed to determine if obesity paradoxically improved outcomes in patients with acute myocardial infarction (AMI) as well as compare outcomes of mild to moderately obese patients and morbidly obese patients to non-obese patients. Materials and methods Data was obtained from the Nationwide Inpatient Sample (NIS) for 2016 and 2017. The study included adult patients with a principal discharge diagnosis of AMI. This group was divided into ST segment elevation myocardial infarction (STEMI) and non-ST segment myocardial infarction (NSTEMI). Obese patients were subdivided into two groups: mild-moderate obesity and morbid obesity. Primary outcome compared inpatient mortality. Secondary outcomes included rate of percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), composite revascularization, mean length of hospitalization, total hospital charges, and rates of complications. Results In patients with STEMI, mild to moderately obese patients had lower odds of mortality (aOR: 0.80, 95% CI: 0.715-0.906, p < 0.001) compared to non-obese patients. However, morbidly obese patients had higher odds of mortality (aOR: 1.26, 95% CI: 1.100-1.446, p < 0.001) compared to non-obese patients. Mild to moderately obese patients had higher odds of composite revascularization (aOR: 1.24, 95% CI: 1.158-1.334, p < 0.001), PCI (aOR: 1.08, 95% CI: 1.054-1.150, p = 0.014), and CABG (aOR: 1.46, 95% CI: 1.313-1.626, p < 0.001). Conclusion The degree of obesity affects outcome of patients with AMI. Cardiovascular interventions during hospitalizations for AMI also varied with degree of obesity. This may have affected the outcome, especially among morbidly obese patients.
The Impact of Double Layer Membrane Technique on Bone Regeneration in Postextraction Alveoli – A Pathohistological Experimental Study in Dogs

Abstract Post extraction alveolar ridge preservation is a preventive oral surgical procedure aimed to preserve the dimensions of the alveolar ridge after removal of the teeth. According to literature data, the utilization of guided bone regeneration for this purpose is absolutely justified. The aim of this study was to examine the effect of resorbable collagen membranes placed in two layers in respect to the application of membranes placed in one layer to the degree of bone regeneration after a tooth extraction. This experimental study was conducted on six adult dogs. In the first phase all four premolars were extracted on both sides in the lower jaw. After the volume-standardisation with bone drill, three post extraction alveoli were filled with bone substitute of equine origin and then covered with: collagen bioresor bable membrane of porcine origin; collagen bioresorbable membrane of equine origin; pericardial bioresorbable membrane of equine origin. The membranes on the left side were placed in single-layer and on the right side in double-layer manner. After different monitoring periods, histopathological analysis of the samples taken from the experimental regions was performed. A different degree of bone regeneration was achieved between experimental regions in which membranes were placed in one layer and those where membranes were placed in two layers. There was no difference between regions where membranes of different origin were placed in the same manner. The procedure of covering the post extraction alveoli, filled with bone substitute and with resorbable membranes placed in two layers resulted in a higher degree of bone regeneration compared to those where resorbable membranes were placed in one layer.
Influense of curcumin on lifespan if it is applied at the larval stage of drosophila melanogaster

In this study we have applied the different doses of curcumin at the larval stages of a fruitfly Drosophila melanogaster and subsequently ivestigated its effect on the developmental duration and life expectancy of imago. It has been shown a 2-day delay in the hatching of the flies, which were developing in the medium containing 500 mM of curcumin. Exposure to curcumin significantly influenced on the average and maximum lifespan (ALS and MLS respectively) of all Drosofila in the study: ALS – F=13.01, p<0.001 for males and F=14.3, p<0.001 for females; MLS – F=35.9, p<0.001 for males and F=16.7, p <0.001 for females. Thus, the ALS in the males, which at the larval stage were kept in the medium containing 125 mM, 250 mM and 500 mM of curcumin, was significantly higher (p<0.001) comparing to the control. In females, such kind of significant increase in ALS has been shown at a dose of 500 mM of curcumin (p<0.001) in the medium during the developmental stage comparing to the control. In other words, the ALS of the imago has increased in correlation to the increase in the dose of curcumin applied at the developmental stage in males by 9%, 16%, 13%, and 23% and in females by 0%, 1%, 3%, 16% respectively. There has been also shown the sharp raise in MLS in both males and females, which at the larval stage were kept in the medium containing more than 125 mM of curcumin. To sum up we can assume that in this study consumption of curcumin at the larval stage of fruit flies significantly increased the developmental duration and life span of adult Drosophila, and this may demonstrate the effect of curcumin on the epigenetic programming of pace of life.

Landscape and Tourism: Evolution of Research Topics

Tourism and landscape are broad and complex scientific research fields, as is the synergy between them has given rise to a volume of articles diverse in nature, subject matter and methodology. These difficulties mean that, at present, there is no complete theoretical framework to support this tourism and landscape research, nor complete knowledge of its structure and organization. This motivates the present work, which constitutes the first attempt at mapping this research topic by applying bibliometric techniques using VOSviewer and Science Mapping Analysis Software Tool (SciMAT) software. A total of 3340 articles from journals indexed in Web of Science were analyzed. The results obtained confirm that interest in the study of these concepts has been growing, especially in the last decade. The main contribution of this work lies in the identification of work themes that were basic to the construction of the field but that are currently in decline, such as “cultural heritage” and other themes important to the field that should continue to be dealt with, such as “national parks” or “geotourism”. The transversal nature of sustainability that appears in the network of keywords related to currently emerging themes, such as “planning” and “environment”, is also highlighted and reinforced.
Estructura del cotiledón de la semilla de almendra (Prunus amygdalus L.) cruda, remoj ada y tostada / Cotyledon structure of raw, soaked and roasted almond (Prunus amygdalus L.)

The microstructure of the sweet almond (variety Marcona) and the most important microstruc tural changes caused after roasting (150 °C, 45 min) and soaking (H2O and NaCl 5%, 24 h) were studied by scanning electron microscopy (SEM). The majority of the cotyledon tissue is made up of rather large, nearly isodiametric parenchyma cells with a thick cell wall; the cell-to-cell junc tions are characterized by a distinct middle lamella. The cytoplasmatic membrane delimits the cellular content, protein bodies and lipid bodies being the major components. A cytoplasmic network consisting of the membranous system structured as hexagonal cells extends throughout each parenchyma cell, and surrounds the major components. The parenchymatic tissue is surrounded by a layer of epidermic cells and tegument. After roasting, the cellular organization is lost and the cytoplasmic network surrounding the lipid bodies and protein bodies is altered; the heat destroys some middle lamellae of cell-to-cell junctions; the cytoplasmic compartimental ization of the oil is lost in most cells and the oil drops coalesce; protein bodies are distended and aggregated; other thermal modifications of roasting included pitting and pock-marking of the epidermis and protein bodies, caused by the escape of steam and oil. Soaking in water did not cause drastic changes in the structure; the most significant modification was an alteration of the cytoplasmic network and membrane; soaking in 5% NaCl also produced a partial disolution of protein bodies.
