Published: June 2022

Objective:

Despite the numerous benefits of regular exercise participation for cancer survivors, nearly 60% of survivors do not meet current guidelines. Hospital-based exercise oncology programs may be one strategy to promote exercise engagement as survivors have expressed a preference for exercise programs associated with a cancer hospital. However, follow-up rates in hospital-based exercise oncology programs can be low. Follow-up assessments are a critical component of exercise oncology programs as they determine survivor progress, allow for revision of exercise prescriptions, and demonstrate the effectiveness of the exercise program. Therefore, the purpose of this study was to identify clinical and demographic factors associated with not attending a 12-week follow-up assessment in a hospital-based exercise oncology program.

Methods:

We analyzed data collected from 2016 to 2019 (n = 849) from the Huntsman Cancer Institute’s hospital-based exercise oncology program, the Personal Optimism with Exercise Recovery (POWER) program. Cancer survivors completed an assessment at the start of POWER and were encouraged to attend a 12-week follow-up assessment. Factors associated with not attending a 12-week follow-up assessment were identified using logistic regression.

Results:

Multiple myeloma cancer survivors were more likely (OR 2.33; 95% CI 1.09, 4.98) to not attend a 12-week follow-up assessment, whereas endometrial cancer survivors were less likely (OR 0.39; 95% CI 0.18, 0.87). Greater travel time (OR 2.69; 95% CI: 1.83, 3.96) and distance (OR 2.37; 95% CI: 1.61, 3.49) were associated with not attending a 12-week follow-up assessment. Immunotherapy (OR 1.66; 95% CI 1.02, 2.72), waist circumference (OR 1.01; 95% CI 1.00, 1.02), overweight status per body mass index (OR 1.62; 95% CI 1.11, 2.38), and male sex (OR 1.70; 95% CI 1.23, 2.35) were associated with an increased likelihood of not attending a 12-week follow-up assessment. Survivors with a higher baseline quality of life (OR 0.96; 95% CI 0.93, 0.99) and peak oxygen consumption (OR 0.97; 95% CI 0.95, 0.99) were less likely not to attend a 12-week follow-up assessment.

Conclusions:

Both clinical and demographic factors were associated with not attending a 12-week follow-up assessment in a hospital-based exercise oncology program. Understanding factors related to follow-up assessment attendance in exercise oncology programs can inform the development of targeted interventions to improve follow-up rate thus maximizing exercise support for cancer survivors.

Published: June 2022

This study aimed to investigate the effect of a walking football (WF) program during Ramadan fasting (RF) on heart rate variability (HRV) indices, body composition, and physical fitness in middle-aged males. Thirty-one healthy sedentary men were randomized to WF ( n = 18) and control ( n = 13) groups. Both groups participated in RF. The WF group were involved in a training program (small-sided games) of three sessions a week during RF. The time and frequency domains of HRV, body composition, handgrip, lumbar strength, Modified Agility Test (MAT), and 6-minute walk test (6MWT) were measured before Ramadan (BR), during Ramadan (DR), and after Ramadan (AR). We reported that RF has significantly altered some parameters of HRV DR; the mean HR decreased while the mean RR, LF, and HF increased. WF had a significant effect on HRV and mean HR DR compared with BR and AR decreased while mean RR, HF and LF increased. DR, body mass decreased in both groups, while body mass index (BMI) decreased and lean mass increased only in WF group. Lower body mass and BMI levels were reported AR only in WF group. Physical capacity improved AR, compared with BR, only in the WF group with longer distance in 6MWT, shorter time(s) in MAT, and higher lumbar strength levels. We conclude that RF increases parasympathetic system activity. WF practice during RF is safe and might improve body composition, physical fitness, autonomic cardiac function, and physical fitness in middle-aged males.

Published: June 2022

There is a need to further explore the relationship between atypical symptom reporting and stage diagnosis to help develop a clearer defined list of possible testicular cancer (TC) symptoms that could assist physicians diagnose the disease earlier. A cross-sectional study was employed to explore possible associations between TC symptom presentation and stage of diagnosis. An original 40-item survey was distributed among 698 TC survivors to determine the potential impact of several risk factors, experiences, and behaviors upon diagnosis. This analysis aimed to explore how certain patient-driven experiences (e.g., symptoms, perceptions, and behaviors) could serve as catalysts for seeking medical care for testicular health concerns. Experiencing hot flashes or having no symptoms had a positive association with later-stage diagnosis while change in shape had a significant negative association with later-stage diagnosis. While the logistic regression model explained relatively low variance in the data ( R2 = .1415), it was statistically significant (χ2 p < .001). Pain (odds ratio [OR] = 1.6524, p < .05), hot flashes (OR = 5.7893, p < .01), and no symptoms experienced (OR = 12.4836, p < .01) were all significant predictors of a more advanced stage diagnosis. The concern around uncommon/atypical symptoms are that they are indistinct and do not serve as clear signs that TC is present. However, perhaps in tandem with other more overt symptoms, their discovery can serve in a more confirmatory role for a suspect case. If observed with other uncommonly reported symptoms, these uncommon symptoms could provide another pathway in the TC diagnostic process. Clinical and patient education is warranted to increase awareness of uncommon TC symptoms.

Published: June 2022

In this paper, long short-term memory (LSTM) and Transformer neural network models were developed for classification of different conveyor belt conditions (loaded and unloaded). Comparative shallow models such as logistic regression, support vector machine and random forest were also developed and summarized. Six different-length belt pressure signals were analyzed: 0.2, 0.4, 0.8, 1.6, 3.2, and 5.0 s. Both LSTM and Transformer models achieved 100% accuracy using pressure raw signal. Furthermore, LSTM model reached the highest classification level with the shortest signals. Accuracy and F1-score of 98% and 100% were reached using only 0.8 and 1.6 s-length signals, respectively. Also, LSTM model performed training and testing procedures faster than Transformer. Random forest model demonstrated the best classification level using aggregated signal data with accuracy of 85% and F1-score for loaded and unloaded conditions of 85% and 69%, respectively. Loaded conveyor belt condition was significantly easier to classify than the unloaded one in all models. Only LSTM showed better classification recall for unloaded conveyor belt condition using short signal. Experimental research dataset CORBEL (Conveyor belt pressure signal dataset) and models are open-sourced and accessible on GitHub https://github.com/TadasZvirblis/CORBEL .
OHVIRA syndrome: Early recognition prevents genitourinary complications
Authors: Sijmons Anne , Broekhuizen Suzanne , van der Tuuk Karin , Verhagen Martijn , Besouw Martine
Published: June 2022

Introduction:

The obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome is characterized by the triad uterus didelphys, obstructed hemivagina, and ipsilateral renal dysplasia. To make a radiological diagnosis, knowledge of this syndrome is of paramount importance. Early recognition may prevent complications such as unnecessary surgical procedures, endometriosis, and infections, which could adversely affect fertility.

Case report:

A 1-day-old female newborn in whom a right-sided cystic kidney abnormality was seen on antenatal ultrasound was admitted with anuria and intralabial mass. Besides the multicystic dysplastic right kidney, ultrasound revealed a uterus didelphys with right-sided uterus dysplasia, an obstructed right hemivagina, and an ectopic ureteric insertion. The diagnosis of obstructed hemivagina and ipsilateral renal anomaly syndrome with hydrocolpos was made and the hymen was incised. Later, ultrasound helped in diagnosing a pyelonephritis in the afunctional right kidney that was not draining into the bladder (hence no culture could be obtained), requiring intravenous antibiotics and a nephrectomy.

Discussion:

Obstructed hemivagina and ipsilateral renal anomaly syndrome is an anomaly of the Müllerian and Wolffian ducts of unknown cause. Patients typically present after menarche with (progressive) abdominal pain, dysmenorrhea, or urogenital malformations. In contrast, prepubertal patients can present with urinary incontinence or an (external) vaginal mass. The diagnosis is confirmed by an ultrasound or magnetic resonance imaging. Follow-up includes repeated ultrasounds and monitoring of kidney function. Treatment consists of drainage of the hydrocolpos/hematocolpos; in some cases, further surgery is indicated.

Conclusion:

Consider obstructed hemivagina and ipsilateral renal anomaly syndrome in girls with genitourinary abnormalities: early recognition prevents complications later in life.
Determinants of extinction in a streamed trial procedure
Authors: Witnauer James E , Castiello Santiago , Fung Ethan , Pitliya Riddhi J. , Murphy Robin A , Miller Ralph R
Published: June 2022

The strength of an association between a cue and its outcome is influenced by both the probability of the outcome given the cue and the probability of the outcome in the absence of the cue. Once an association has been formed, extinction is the procedure for reducing responding indicative of the association by repeated presentation of the cue without the outcome. The present experiments tested whether cumulative frequency and/or cumulative duration of these events affects associative extinction in a streamed trial extinction procedure with human participants. Experiment 1 assessed the effects of parametric manipulations of the frequency and duration of either the cue by itself or cue–outcome co-absence. In Experiment 1, participants proved relatively insensitive to manipulation of the event’s duration. In contrast, judgements of the association by participants decreased when the frequency of cue-alone events was increased, even when the durations of those events were decreased so that cumulative exposure to the cue was equated. No effect of either the duration or the frequency of cue–outcome co-absence was observed. Experiment 2 demonstrated that the effect of cue-alone (i.e., extinction trial) frequency generalises across a wide range of parameters for initial acquisition achieved by cue–outcome pairings. Experiment 3 tested for an interaction between event duration during initial learning and event duration during extinction. Collectively, these results indicate that the cumulative frequency, and not the cumulative duration, of extinction trials as well as the duration of the cue–outcome co-absences between extinction trials control the effectiveness of an extinction procedure.

Published: June 2022

Background:

Post-stroke delirium (PSD) is a modifiable predictor for worse outcome in stroke. Knowledge of its risk factors would facilitate clinical management of affected patients, but recently updated national guidelines consider available evidence insufficient.

Aims:

The study aimed to establish risk factors for PSD incidence and duration using high-frequency screening.

Methods:

We prospectively investigated patients with ischemic stroke admitted within 24 h. Patients were screened twice daily for the presence of PSD throughout the treatment period. Sociodemographic, treatment-related, and neuroimaging characteristics were evaluated as predictors of either PSD incidence (odds ratios (OR)) or duration (PSD days/unit of the predictor, b), using logistic and linear regression models, respectively.

Results:

PSD occurred in 55/141 patients (age = 73.8 ± 10.4 years, 61 female, National Institutes of Health Stroke Scale (NIHSS) = 6.4 ± 6.5). Age (odds ratio (OR) = 1.06 (95% confidence interval (CI): 1.02–1.10), b = 0.08 (95% CI = 0.04–0.13)), and male gender ( b = 0.99 (95% CI = 0.05–1.93)) were significant non-modifiable risk factors. In a multivariable model adjusted for age and gender, presence of pain (OR < sub >  mvar = 1.75 (95% CI = 1.12–2.74)), urinary catheter (OR < sub >  mvar  = 3.16 (95% CI = 1.10–9.14)) and post-stroke infection (PSI; OR < sub >  mvar  = 4.43 (95% CI = 1.09–18.01)) were predictors of PSD incidence. PSD duration was impacted by presence of pain ( b < sub >  mvar = 0.49 (95% CI = 0.19–0.81)), urinary catheter ( b < sub >  mvar  = 1.03 (95% CI = 0.01–2.07)), intravenous line ( b < sub >  mvar = 0.36 (95% CI = 0.16–0.57)), and PSI ( b < sub >  mvar = 1.60 (95% CI = 0.42–2.78)). PSD (OR = 3.53 (95% CI = 1.48–5.57)) and PSI (OR = 5.29 (95% CI = 2.92–7.66)) independently predicted inferior NIHSS at discharge. Insular and basal ganglia lesions increased the PSD risk about four- to eight-fold.

Discussion/Conclusion:

This study identified modifiable risk factors, the management of which might reduce the negative impact PSD has on outcome.

Authors: Clarke Rachel , Chow Homen , Kerrison Kristy
Published: June 2022

Background

Peer support groups reduce psychological morbidity and increase social support for Intensive Care Unit (ICU) survivors. Group formats differ and research, although emerging, is limited. This study explores a continuously running ICU Expert by Experience group, which has a dual role of support and service-user consultative, from attendees’ perspectives.

Methods

A thematic analysis was conducted on interviews with current and past members of an ICU Expert by Experience group. 11 participants took part in online and telephone interviews. Three provided written responses. Final themes were created following a process of data validation with participants.

Results

Four main themes emerged: (1) Support in the difficult recovery journey (2) Relationships and shared experiences (3) Value of professional facilitation (4) Practical considerations.

Conclusion

Patients highlighted the help gained from the group as an integral part of their recovery journey. Results also identified practical implications for those considering setting up similar support groups.

Published: June 2022

A testing protocol for conducting biomechanical underhand serve-reception evaluation in volleyball in match-like conditions is presented. A launcher sends a ball over the net toward the reception zone for the player to pass it to the setter; the ball is tracked with video cameras and the player’s articular information is captured by inertial sensors, force plates, and video cameras. Test-retest reliability and, known-groups and concurrent validity of the test are evaluated. Left knee, right knee, left shoulder, and right shoulder angles were highly reliable (ICC > 0.88), with low standard errors of measurement (%SEM < 13.07). Resultant normalized ground reaction forces were also reliable (ICC: 0.76, %SEM: 9.14). Professional and amateur athletes’ comparisons were statistically significant and non-trivial ( p < 0.05, Cohen’s d > 0.49), with professionals’ body movements presenting small variance and symmetry between left and right limb variables, and amateurs’ presenting higher variance and greater asymmetry. Finally, each athlete’s left limb angles were compared against their corresponding sagittal Kinovea measurements for concurrent validity, obtaining acceptable correlation scores for amateur athletes (PCC > 0.79) and good correlation scores (PCC > 0.83) for professional athletes. The test offers a reliable and valid method for evaluating underhand serve-reception biomechanics in volleyball players.

Published: June 2022

In New Zealand, mental health issues have created a ‘silent epidemic’ with diverse consequences in mental health outcomes. Poor mental health state along with inequities to access services are persistent. Key areas of mental health promotion in New Zealand that require constant attention are appropriate policymaking, reaching out to all communities, interventions at the individual level, and the complexity of the mental health system. This commentary evaluates the inadequacies faced by the public in accessing mental health services and the directions to improve in the future. It also reviews the New Zealand government’s ‘Like Mind, Like Mine’ program, aiming to provide socially inclusive services to people to live a life free from mental health-related stigma or discrimination.

Published: June 2022

Autonomic nervous system disorders have many causes, and thus, no effective remedy for these disorders has been established. In this study, we conducted animal experiments with essential oil from Pelargonium graveolens (EOPG, geranium essential oil), which may regulate the autonomic nervous system. EOPG was administered to awake mice by inhalation. Heart rate variability (HRV) was analyzed from the pulse wave of the mice on an elevated platform, and the ratio of sympathetic to parasympathetic nerve activity was determined. The results showed that inhalation of EOPG did not affect the heart rate but made activity of the parasympathetic nervous system dominant. This effect was thought to be due to linalool, a component of EOPG that was transferred into the brain and body.
School Nurses on the Front Lines of Healthcare: Emergencies Associated With Sport and Physical Activities (Part 3): Shortness of Breath in a Pediatric Athlete During a Track Event
Authors: Swaffield Thomas P. , Olympia Robert P.
Published: June 2022

Sport participation is an important part of the development, both physically and mentally, of children and adolescents in the United States. Illness and injury associated with sport and physical activities may occur in the school setting. Although most sport-related illness and injury in students are considered minor emergencies, life-threatening illnesses or injuries may occur. It is important for the school nurse to recognize potential life-threatening emergencies associated with sport and physical activity, to initiate stabilization of the student with life-threatening symptoms, and to triage these students to an appropriate level of care (back to the classroom, home with their guardian with follow-up at their primary healthcare provider’s office, or directly to the closest emergency department [ED] via Emergency Medical Services [EMS]). This article specifically describes the initial assessment and management of shortness of breath in an adolescent athlete during a track event.

Published: June 2022

Digitalization captures most aspects of human life. New trends in digitalization have a great impact on the retail chain stores; hence, the implementation of artificial intelligence (AI) has somewhat become necessary to cope up with the changing trend in this sector. This case study analyses the use of artificial intelligence in an unstaffed supermarket called LIFVS located at the rural areas of Sweden. As the number of supermarkets was decreasing in the rural areas over the years due to high maintenance costs, many have opted out of business. In response to the situation, Co-founder Daniel Ludh (hereafter Daniel) implemented a sustainable business model using AI, which serves the purpose of supermarket chains meeting the demands of the consumers in the rural areas while keeping the costs truncated. The case also discusses the various challenges an unstaffed supermarket face and highlights the success of LIFVS, paving the path for the future retailers of the industry.
Trends and characteristics of primary pyogenic spine infections among people who do and do not inject drugs: Northeast New York State, 2007 to 2018
Authors: Sola Steven , O’Connor Casey , Farry Leigh A. , Roddy Kristina , DiRisio Darryl , Dufort Elizabeth M. , Robbins Amy , Tobin Ellis
Published: June 2022

Background:

Pyogenic spine infections (PSIs) are challenging to diagnose and treat. People who inject drugs (PWID) are at increased risk and contribute to rising PSI incidence.

Objective:

To analyze trends and characterize PSI in persons who do and do not inject drugs in northeast New York State (NYS), a predominantly rural region.

Methods:

A retrospective study of PSI patients at a regional tertiary care hospital from 2007 to 2018 was conducted. PSI incidence, population demographics, microbiology, surgical interventions, length of stay (LOS), and costs were compared between injection substance use disorder (ISUD) and non-ISUD cohorts.

Results:

Two hundred and seventy patients (59 ISUD and 211 non-ISUD) were included in this study. PSI incidence due to ISUD increased 1175% during the study time periods. The median age of the ISUD and non-ISUD cohorts was 39 and 65, respectively. Staphylococcus aureus was the most common causative organism, although a variety of bacterial and fungal pathogens were identified. Nearly half of the patients in each cohort required surgical intervention. Median acute care LOS was 12 days and comparable between cohorts. However, the ISUD cohort was frequently discharged against medical advice, or transferred back to acute care hospitals to complete antibiotic courses. Median inpatient hospital costs were approximately $25,000 and were comparable between cohorts. These costs do not reflect inpatient costs once the patient was transferred back to the referring hospital, nor costs for outpatient care. Medicaid and Medicare were the most common primary insurance payers for the ISUD and non-ISUD cohorts, respectively.

Conclusions:

Incidence of PSI has increased significantly coincident with the opioid epidemic and has had significant impact on a large, rural region of NYS. PSIs consume large amounts of healthcare resources. This study can inform hospitals and public health agencies regarding the need for substance abuse harm reduction strategies.

Published: June 2022

Background

Currently bubble continuous positive airway pressure (bCPAP) is commonly used in low resource settings to treat respiratory distress. However, the accumulation of condensate in the patient's exhalation limb during operation could significantly increase pressure delivered to the body, which can lead to severe respiratory failure in the infant. The objective of this research was to develop a novel low-cost bCPAP device that can monitor and control the pressure delivered to infants.

Methods

When the neonate expires, the pressure sensor inside the expiratory limb measures the instant positive end-expiratory pressure. The microcontroller decides whether to turn the relay to switch the path of expiration between the two expiratory tubes connected to the valve outlets. This depends on the pressure reading and the cutoff pressure value inserted by the physician.

Results

The system was tested for accuracy, safety, cost, ease of use, and durability. The prototype was accurate in eight iterations at eight different depths of water that were made to monitor and control the pressure. It was safe and provided suitable pressure for the neonate, and the prototype was built in less than 193 USD.

Conclusions

The performance testing of the device demonstrated accurate and safe control and monitoring of continuous positive air pressure (CPAP) and oxygen levels with humidity levels safe for infants. The device provides humidified, blended, and pressurized gas for the patient. It allows physicians to easily monitor and control the accumulation of condensate in the exhalation limb of the CPAP machine accurately and safely.
An intelligent system for assisting personalized COVID-19 vaccination location selection: Taiwan as an example
Authors: Lin Yu-Cheng , Chen Tin-Chih Toly
Published: June 2022

In many regions of the world, with the gradual increase in the supply of COVID-19 vaccines, COVID-19 vaccination has changed from centralized government control to personalized selection. When choosing a location for COVID-19 vaccination, in addition to subjective preferences, objective information (such as the expected waiting time at a COVID-19 vaccination location and the crowdedness and reliability of the vaccination location) also need to be considered. However, it is not convenient for an individual to collect and compare such information. To address this issue, this research applies web content mining to extract the conditions of COVID-19 vaccination locations. Then, a novel asymmetric calibrated fuzzy inverse of column sum and fuzzy Vise Kriterijumska Optimizacija I Kompromisno Resenje recommendation mechanism is proposed. Finally, an intelligent system is developed to assist a user in selecting a personalized COVID-19 vaccination location. In a regional experiment conducted in Taichung City, Taiwan, the developed intelligent system was applied to assist 20 users in choosing personalized COVID-19 vaccination locations. The successful recommendation rate was 95%.
Engineering Trainee-Teachers’ Attitudes Toward Technology Use in Pedagogical Practices: Extending Computer Attitude Scale (CAS)
Authors: Salele Nafiu , Khan Md. Shahadat Hossain
Published: June 2022

The current study examined the trainee teachers’ attitudes toward technology adoption and use in tertiary engineering education. The Computer Attitude Scale (CAS) was extended by including the social influence component, to examine whether social norms affect the acceptance of technology by teachers. Findings from 110 trainee-teachers revealed that their attitudes toward technology are positive. These attitudes constitute the way they like and intend to use technology, their perception of its usefulness in their daily tasks, and the control they perceived to have over technology while using it in engineering disciplines. The findings also confirm that social influence is an important predictor of trainee teachers’ attitudes toward using technology. Overall, the study provides a new influential factor (social) that could be merged with the other four major components (affect, perceived usefulness, perceived control, and behavioral intention) of CAS in conducting future research. The results of this study further provide useful knowledge that extends prior arguments concerning teachers’ attitudes toward using technology in teaching with respect to age, gender, and disciplines. More specifically, the study, theoretically, contributes to research practice in technology acceptance, by extending the computer attitude scale (CAS), with social influence as an additional important factor to be considered when conducting future research. Therefore, an extended CAS is established for exploring newer research in this domain. Policymakers and designers of teacher professional development will be informed of these findings that will accelerate initiatives of technology integration of engineering education in developing countries and other similar contexts.

With the great economic significance of the souvenir business, academic interest in the souvenir field is increasing. The purposes of this study are to examine the holistic development of souvenirs research from 1981 to 2020, identify research themes and gaps, and suggest future research directions. With the tool of VOSViewer software, bibliometric analysis and systematic quantitative literature review were conducted. The research identifies five existing themes: (1) the souvenir object itself; (2) economic significance and socio-cultural impact; (3) souvenir business and ecology; (4) souvenir shopping behavior; and (5) souvenir shopping satisfaction and its consequences. This thematic map contributes to understanding the essence of souvenirs and their relationship with other tourism system elements; it reveals the possibility of exploring tourism phenomena and addressing the challenges through the souvenir field perspective. It has practical implications for the stakeholders to address issues and struggles for development in the context of the COVID-19 pandemic.
“We Must Work… Toward Justice in Action”: Grievances, Claims Making, and Spillover in the Idle No More Movement
Authors: Schweitzer Julie , Mix Tamara L. , Fleming Olivia M.
Published: June 2022

The Idle No More (INM) movement emerged in reaction to Bill C-45, the Canadian Jobs and Growth Act, in November 2012, inspiring a new wave of activism. Central to the movement’s grievances are Indigenous resistance and environmental justice (EJ), positioning INM’s activities against neo-colonialism, exploitation, and environmental degradation. We build upon existing EJ movements, Indigenous Peoples/Indigenous Environmental Justice (IEJ) movements, and social movement spillover, grievance, and claims making literatures to understand the role of shared movement narratives in encouraging mobilization. INM relies on social media to educate members and construct and communicate movement goals and actions. Analyzing 6 months of Facebook comments, reflecting the INM movement’s emergence period, we argue that INM activists employ structural grievances embedded in previous EJ and Indigenous resistance movements, combined with emerging (incidental) grievances to articulate shared claims that address inequality and justice, appealing to a range of potential supporters. We offer an analysis of the emergent INM movement to consider the active intersection of EJ, Indigenous Peoples, and IEJ movements to mobilize and sustain movement activities in spite of Bill C-45’s passage.
Integrating Social and Emotional Learning: Creating Space for Afterschool Educator Expertise
Authors: White Annie M. , Akiva Thomas , Colvin Sharon , Li Junlei
Published: June 2022

A growing movement suggests that social and emotional learning (SEL) should be integrated into educational experiences in and outside schools. Afterschool programs can be particularly well suited for SEL, and afterschool educators can play an important role in skill development. We interviewed 23 experienced afterschool educators in community-based programs to understand how staff encourage SEL and how program directors support staff in doing so. Findings show that afterschool educators describe integrating SEL into their daily interactions with children by creating and catching teachable moments. Program directors served either as compliance enforcers or partners who supported staff’s autonomy to encourage SEL despite top-down mandates. Findings suggest that educators can develop substantial expertise integrating SEL into their professional work. By recognizing and empowering such expertise, program leaders can support implementation and innovation of SEL practices. Allocating resources toward intentional integration of SEL is an important next step for this work.

This study is a prospective diagnosis study which involved the pediatric nurse evaluation of patient status using modified Pediatric Early Warning Score (NU-PEWS) until the patient was discharged or transferred to PICU. A total of 824 pediatric patients were admitted, 407 participants were enrolled in this study. The NU-PEWS demonstrated the most accurate cut-off point at greater than 3, with 90.5% sensitivity and 89.1% specificity. The receiver operating characteristic (ROC) indicated positive results in the general medical condition (ROC 0.958), gastrointestinal, respiratory, and hematologic diseases (ROC 0.94-0.97) whereas lowest in neurological disease (ROC 0.843). This study validated that NU-PEWS has good performance in detecting deteriorating patients, and that prediction utilizations are good in almost every subgroup of disease, with the exception of neurological disease.

Background. In recent studies, renal ultrasonography and dimercapto-succinic acid (DMSA) scan have a role in predicting vesicoureteral reflux in children with febrile urinary tract infection (UTI). Materials and Methods. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (PLR), and negative likelihood ratio (NLR) were defined for ultrasonography and DMSA scan to predict vesicoureteral reflux in 70 children with febrile UTI. Results. Renal ultrasonography sensitivity, specificity, PPV, NPV, PLR, and NLR for vesicourethral reflux prediction was 0.57, 0, 1, 0, 0.57, and 0.47 and sensitivity, specificity, PPV, NPV, PLR, and NLR of DMSA scan for predicting vesicourethral reflux was 0.75, 0.9, 0.33, 0.98, 7.5, and 0.27, respectively. Conclusions. Ultrasonography cannot predict the presence of VUR, but DMSA scan has a good sensitivity in this context. Therefore, by observation of DMSA scan results, it can be decided whether to perform VCUG or not.

Introduction:

Missed care opportunities (MCOs) contribute to poor health outcomes, and pediatric dental patients are particularly vulnerable; identifying associated patient characteristics will help inform development of targeted interventional programs.

Objective:

To assess socioeconomic and demographic disparities associated with MCOs among children in an urban pediatric hospital’s dental clinic. MCOs lead to a lack of continuous care and increased emergent needs, so understanding MCOs is required to achieve equitable pediatric dental health.

Methods:

A retrospective 2-y (2019–2020) cohort of MCOs in children 1 to 17 y old, with scheduled dental visits. MCOs were defined as appointments not attended or canceled and not rescheduled prior to initial scheduled visit. Multivariable mixed-effects logistic regression models with patient-level clustering assessed the associations of demographics, neighborhood-level socioeconomic factors (using social vulnerability index [SVI]), and clinic characteristics with MCOs.

Results:

Of 30,095 visits, 30.9% were MCOs. Multivariable logistic regression estimated increased likelihood of MCOs in Black/non-Hispanic (odds ratio [OR], 1.20; 95% confidence interval [CI], 1.09–1.32) and Hispanic (OR, 1.18; 95% CI, 1.06–1.31) patients, patients with public insurance (OR, 1.25; 95% CI, 1.15–1.36) or no insurance (OR, 1.46; 95% CI, 1.15–1.85), patients with complex chronic conditions (OR, 1.11; 95% CI, 1.03–1.19), visits scheduled during the COVID-19 pandemic (OR, 9.48; 95% CI, 8.89–10.11), appointments with wait days over 21 d (OR, 4.07; 95% CI, 3.49–4.74), and children from neighborhoods of high social vulnerability (75th percentile SVI) (OR, 1.08; 95% CI, 1.01–1.16).

Conclusions:

Children with highest dental MCOs were from neighborhoods with high SVI, had public insurance, and were from marginalized populations. MCOs contribute to inequities in overall health; hence, interventions that address barriers related to characteristics associated with pediatric dental MCOs are needed.

Knowledge Transfer Statement:

Missed care opportunities contribute to poor health outcomes; identifying associated patient characteristics will help inform development of targeted interventional programs. Providing these findings to stakeholders will better impart understanding access barriers and drive research and program development. Dissemination of this information in the form of altering appointment practices will better accommodate specific patient population needs.

Blue-green algae is an environmental problem; they reproduce rapidly and threaten aquatic ecosystems. Therefore, research on their use as a new energy resource is being actively conducted in various fields. This study was carried out to apply the natural dye from blue-green algae to the textile dyeing industry. Two methods were used to dye cotton and silk fabrics using blue phycocyanin dye extracted from blue-green algae. Six mordants were also tested in the process. The dyed fabrics were evaluated through dyeing depth and color fastness (washing, rubbing, dry cleaning, and light) tests. Phycocyanin dyed both fabrics blue and the dyeing effect was better on silk than on cotton fabric. In addition, Al, Sn, and Fe mordants were most effective for dyeing fabrics and co-mordants were more effective than pre-mordants.

Textile wastewater treatment is a complex process that requires a range of chemicals and generates hazardous sludge. This article evaluates a chemical-free, floating treatment wetlands system for the treatment of textile wastewater containing reactive red and reactive yellow dyes. Two aquatic plants, Eichhornia crassipes Solms and Pistia stratiotes L., were selected and vegetated in the system. The efficacy of the system was enhanced by inoculation of two pollutant-degrading and plant growth-promoting bacteria: Bacillus cereus and Bacillus subtilis. The eight treatments were designed with different combinations of plants and bacteria. The performance of the system was evaluated through key parameters of electrical conductivity, total dissolved solid, total suspended solids, biological oxygen demand, chemical oxygen demand, and dye concentration for the treated wastewater. The best treatment achieved the optimized plant–bacteria synergism and exhibited good reductions in the physicochemical parameters and the values of all the wastewater parameters were within the limits set in the standards of National Environmental Quality Standards and Zero Discharge of Hazardous Chemicals Program.

Clothing and bedding that are labeled as “wrinkle-free,” “iron-free,” or “easy-care” use formaldehyde resins that can release a significant amount of formaldehyde. For patients who are allergic to formaldehyde, this can trigger allergic contact dermatitis. Unlike many other countries, formaldehyde levels in clothing are not regulated in the United States. The purpose of this study is to measure the amount of formaldehyde released from a variety of men’s dress shirts, women’s clothing, children’s clothing, and pillowcases, before washing and after washing using a Rotawash. This study has also looked at whether the price of an item has any correlation with the amount of formaldehyde released.

Published: June 2022

In order to impart good application properties to locust bean gum size for all-polyester yarn, a series of acrylate monomers including methyl acrylate, ethyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, and common hydrophilic monomer–acrylic acid were grafted onto molecular chains of native locust bean gum to obtain locust bean gum- g-P(AA-co-acrylate) products with similar grafting ratios through Fenton’s reagent, respectively. The effects of carbon chain length of the series of acrylates on sizing properties of the grafted locust bean gum for polyester warp were studied. It was found that by grafting acrylates onto the molecular chains of locust bean gum the sizing properties of the locust bean gum were improved markedly. Under the condition of similar grafting ratios, locust bean gum- g-poly(AA-co-methyl acrylate) showed the highest apparent viscosity, water solubility, film strength, wettability, and adhesion to polyester fiber in all the grafted locust bean gum prepared. Meanwhile, locust bean gum- g-poly(AA-co-butyl acrylate) and locust bean gum- g-poly(AA-co-2-ethylhexyl acrylate) had the highest wear resistance and elongation of sizing film, respectively. The modified locust bean gum grafted with acrylate monomers with different carbon chain lengths was able to meet various requirements in the sizing process for polyester yarn.

Background:

This is a retrospective review of patients who have had a Lapidus procedure for hallux valgus deformity correction, performed by a single surgeon.

Methods:

The clinical records, operation notes and available weightbearing preoperative and postoperative radiographs of all patients who had a Lapidus procedure between February 2008 and July 2018 for hallux valgus deformity were reviewed. The preoperative and postoperative hallux valgus angle (HVA), intermetatarsal angle (IMA), and talometatarsal angle (TMT) on anteroposterior (AP) and lateral radiographs were recorded. The postoperative Foot and Ankle Ability Measure (FAAM) scores were obtained from phone interviews.

Results:

Two hundred thirteen Lapidus procedures were identified between February 2008 and July 2018 and included in the final analysis. The average preoperative and postoperative HVA was 36.3 and 18 degrees, respectively, with an average improvement of 18.3 degrees. The average TMT angles showed a preoperative and postoperative difference of 1.1 degrees on the AP radiograph and 2.4 degrees on the lateral. The average preoperative and postoperative IMA angles were 16.5 and 7.4 degrees, respectively, with an improvement of 9.1 degrees. There were 9 cases (4.2%) of nonunion confirmed on radiography, of which 3 cases (1.4%) had revision fixation with bone graft and went on to radiologic union. Final FAAM scores were available for 151 patients (70.9%). From this group, 74.8% (113/151) scored higher than 90%, 16.6% (25/151) scored between 70% and 90%, and 8.6% scored between 50% and 70%. The patient satisfaction rate was 92.9% overall.

Conclusion:

This single-surgeon retrospective review of a relatively large number of Lapidus procedures reports acceptable radiologic correction and patient satisfaction.

Level of Evidence:

Level IV, Large case series.
