Authors: Raposo-Amaral Cassio Eduardo , Denadai Rafael , Máximo Geiza , Raposo-Amaral Cesar Augusto , Ghizoni Enrico 
Published: April 2020

Background:
Pfeiffer syndrome (PS) is a very rare condition with a wide clinical spectrum. There are only a few studies that address the classification and treatment of PS and take into account the most commonly presented clinical features. Thus, the objectives of this study are to propose an algorithm for PS management based on a modified severity scale and correlate PS severity with tracheostomy placement.

Methods:
An observational retrospective study was performed on consecutive patients with PS (n = 12), who underwent surgery between 2008 and 2018. Clinical features and findings of all included patients with PS were classified as types A, B, and C, which guided treatment workflow. The Fisher test was used to correlate the severity of patients with PS with tracheostomy placement.

Results:
There were 12 patients, classified as type A (n = 3), type B (n = 6), and type C (n = 3). All patients who received tracheostomies (n = 6) were stratified into the severe category (n = 9; types B and C) (P < 0.05). There were 4 minor complications, and 1 major complication according to a modified Clavien–Dindo surgical complication scale.

Conclusion:
A treatment algorithm based on the 3 different Pfeiffer types was proposed. Severity of PS statistically correlates to tracheostomy placement.
ANATOMICAL AND VISUAL OUTCOMES IN STAGE 5 RETINOPATHY OF PREMATURITY WITH MICROINCISION VITRECTOMY SURGERY
Authors: Sen Parveen , Bhende Pramod , Rishi Ekta , Gopal Lingam , Jain Smriti 
Published: April 2020

Purpose:
To report anatomical and visual outcomes and potential prognostic factors with microincision vitrectomy surgery in Stage 5 retinopathy of prematurity.

Methods:
The medical records of premature babies who underwent microincision vitrectomy surgery for Stage 5 retinopathy of prematurity using 23G, 25G, or 27G instrumentation and had a minimum follow-up of 6 weeks were, retrospectively, analyzed. Primary outcome measures were anatomical success at last follow-up defined as retinal attachment at the posterior pole and visual outcomes. Potential risk factors and complications influencing anatomical outcomes were also analyzed.

Results:
One hundred seventy eyes of 115 infants underwent lensectomy and vitrectomy with microincision vitrectomy surgery. After a mean follow-up of 30.59 ± 33.24 weeks, anatomical success was achieved in 56 eyes (33.7%) of 166 eyes that had a minimum follow-up of 6 weeks. Occurrence of vitreous hemorrhage was more with 23 gauge (62.27%) as compared to 25 gauge (37.73%) (P = 0.024). With increase in age with each week, the probability of achieving anatomical success was found to be significantly more (odds ratio 1.030; confidence interval = 1.010–1.060; P = 0.008). Presence of anterior segment pathology was associated with poor anatomical outcomes (odds ratio 2.480; confidence interval = 1.190–5.160; P = 0.010). Seventeen children with attached retina had a follow-up of 14 months–5 years, of which ambulatory vision was recorded in five eyes and the ability to identify objects close to face in 12 eyes.

Conclusion:
Although surgery for Stage 5 retinopathy of prematurity is challenging, anatomical success can be seen in one-third of cases with microincision vitrectomy surgery. Visual prognosis may be limited but still beneficial.

Authors: Venkat Arthi G. , Abraham Joseph R. , Bessette Angela , Karthik Naveen , Baynes Kim , Lowder Careen Y. , Srivastava Sunil 
Published: April 2020

Purpose:
Chronic postoperative endophthalmitis is a known complication of cataract surgery. Here, we report a case of chronic endophthalmitis following uncomplicated cataract surgery secondary to the atypical bacterium Aquamicrobium terrae.

Methods:
Retrospective case report of a single patient with endophthalmitis secondary to A. terrae.

Results:
A 61-year-old healthy patient presented with recurrent iridocyclitis following uncomplicated cataract surgery. Repeated attempts to taper off topical steroid eyedrops were unsuccessful. Anterior chamber paracentesis cultures and vitrectomy cultures grew the same gram-negative bacillus, A. terrae, on six different occasions. The patient was treated initially with a series of intravitreal ceftazidime injections and adjuvant oral minocycline with recurrence of inflammation necessitating pars plana vitrectomy with intraocular lens removal and total capsulectomy. Inflammatory episodes recurred until residual capsule fragments were ablated using endoscopic vitrectomy. Since ablation over 18 months ago, no further recurrences have occurred and the patient has excellent visual outcome.

Conclusion:

A. terrae is a gram-negative bacillus recovered from polluted soil. This is the first case of postoperative endophthalmitis secondary to A. terrae and the first description of human infection caused by this newly identified microbe.

Published: April 2020

Abstract
A 74-year-old woman with hyperthyroidism was referred for radioiodine therapy. The patient was accidentally given 60 mCi of 177Lu-PSMA orally instead of 131I. Upon discovery of this medical event, we immediately started radiation protective actions including hydration, antiemetics, and laxatives. The patients did not have any symptoms. Static acquisition was performed from the abdominal-pelvic and head and neck regions at 20 and 90 hours after ingestion, which showed prominent intestinal activity and mild systemic activity in the kidneys, bladder, salivary, and lacrimal glands.

Published: April 2020

Objective
This study aimed to assess the general dermatological needs and correlation of tentative skin cancer screening diagnoses with histopathological confirmation in the highly sun-exposed locals of the Galapagos Islands.

Methods
An institutional review board–approved prospective study was performed at Blanca's House, a nonprofit surgical volunteer organization, free clinics in the Galapagos. After consent, a 40-item modified SPOTme-inspired questionnaire was completed. Partial or total body skin examinations were conducted by board-certified dermatologists. Board-certified plastic and general surgeons performed excisional biopsies on suspicious lesions. Individuals younger than 18 years, and non-Spanish or non-English speakers were excluded.

Results
A total of 273 patients were included in the study, of which 202 reported skin concerns. Benign nevi (n = 76), seborrheic keratosis (n = 42), melasma (n = 19), actinic keratosis (n = 16), acne (n = 15), eczema (n = 13), fungal infections (n = 12), seborrheic dermatitis (n = 5), and psoriasis (n = 5) were most commonly identified.
Twelve patients (4.4%) had presumptive skin cancer after screening. Six of 8 biopsies confirmed cancer (group 1), 2 declined a biopsy and 2 were unresectable. Seven basal cell carcinomas and one squamous cell carcinoma were excised with clear margins. A right lower eyelid melanoma was diagnosed and subsequently treated in the United States where invasive melanoma with a Breslow thickness of 0.3 mm was found.
Compared with the noncancer group (group 2: n = 265), group 1 had significantly higher likelihood of reporting having seen a dermatologist (P = 0.02), taking any medications (P = 0.0001), having blonde or red hair (P = 0.01), having blue or green eyes (P < 0.0001), and having used indoor tanning equipment (P < 0.0001). Group 1 was also more likely to report 4 or more blistering sunburns (P = 0.08), which approached significance. When evaluated by a dermatologist, group 1 was significantly more likely to be classified as “high risk” for developing cancerous lesions (P < 0.0001) compared with group 2.

Conclusions
Skin concerns in the Galapagos included benign and malignant conditions. There is a need for dermatological care in this medically underserved population. This modified SPOTme-inspired skin cancer questionnaire, confirmed by histology, is a useful tool in identifying high-risk patients and detecting skin cancer in international communities that would have otherwise experienced delays in diagnosis or treatment.
Medial Sural Artery Perforator Flap for Leg and Knee Coverage
Authors: Luca-Pozner Vlad , Delgove Anais , Kerfant Nathalie , Karra Amir , Herlin Christian , Chaput Benoit 
Published: April 2020

Background
For soft-tissue defect coverage in the lower leg and around the knee joint, the gastrocnemius muscle flap is the most commonly used. Having constant anatomy, a long pedicle, and decreased donor site morbidity, the medial sural artery perforator (MSAP) flap may represent a good reconstructive alternative. The aim of this report was to present the experience of using a dual perforator MSAP pedicled flap.

Methods
Nineteen patients underwent soft-tissue reconstruction by MSAP flap in the one third of the lower leg and around the knee joint. Eleven patients were injured in traffic accidents. Exposure of a knee prosthesis required flap coverage in 4 cases. The other defect etiologies were a gunshot wound, bone abscess due to a sickle cell anemia, bone exposure due to a full thickness burn, and sarcoma resection. Defect dimensions ranged from 7 × 5 cm to 15 × 8 cm. Seventeen flaps were harvested with 2 perforators. Donor sites were closed primary in 16 of the 19 cases.

Results
The sizes of the MSAP flaps ranged from 7 to 22 cm × 5 to 8 cm. The procedure was uneventful in 17 cases. The 2 unsuccessful flaps developed a distal necrosis, for which an excision with direct suture was made secondary. Complete healing was achieved in all cases.

Conclusions
The pedicled MSAP flap represents a versatile option in soft-tissue defect coverage of the lower leg and around the knee joint. Inclusion of 2 perforators could render the flap safer and increase its skin paddle, making it suitable for larger defects.
Estimation of COVID-19 spread curves integrating global data and borrowing information
Authors: Lee Se Yoon , Lei Bowen , Mallick Bani K. 
Published: April 2020

AbstractCurrently, novel coronavirus disease 2019 (COVID-19) is a big threat to global health. The rapid spread of the virus has created pandemic, and countries all over the world are struggling with a surge in COVID-19 infected cases. Scientists are working on estimating or predicting infection trajectory for the COVID-19 confirmed cases, which will be useful for future planning and policymaking to effectively cope with the disease. There are no drugs or other therapeutics approved by the US Food and Drug Administration to prevent or treat COVID-19: information on the disease is very limited and scattered even if it exists. This motivates the use of data integration, combining data from diverse sources and eliciting useful information with a unified view of them. In this paper, we propose a Bayesian hierarchical model that integrates global data to estimate COVID-19 infection trajectories. Due to information borrowing across multiple countries, the proposed growth curve models provide a powerful predictive tool endowed with uncertainty quantification. They outperform the existing individual country-based models. Additionally, we use countrywide covariates to adjust infection trajectories. A joint variable selection technique has been integrated into the proposed modeling scheme, which aimed to identify the possible country-level risk factors for severe disease due to COVID-19.
Finding an optimal blade-profile to improving the performance of partially admitted turbines
Authors: Togh Reza Aghaei , Karimi Mohammad Mahdi 
Published: April 2020

Purpose
This paper aims to present the designing and investigating various types of impulse blade profiles to find the optimal profile that has better performance than the first or original blade. The studied model is a turbine with an output power below 1 MW and a large pressure ratio up to 20, which is used to gain relatively high specific work output. As a result of its low mass flow rate, the turbine is used under partial-admission conditions. The turbine’s stator is a group of convergence–divergence nozzles that provide supersonic flow.

Design/methodology/approach
More than 10 types of two-dimensional blade profiles were designed using the developed preliminary design calculations and numerical analysis. The numerical results are validated using the existing experimental results. Finally, the case with improved performance is introduced as the final optimum case.

Findings
It was found that the performance parameters such as efficiency, power and torque are increased by more than 8% in the selected best model, in comparison with the original model. Moreover, the total pressure loss is 12% decreased for the selected model. Finally, the selected profile with superior performance is proposed.

Originality/value
Simultaneous numerical tests are conducted to examine the interaction of different supersonic blade profiles with the partially injected flow to the rotor.
Reorienting business education through the lens of Ernest Boyer
Authors: MacAulay K. Doreen , Mellon Mark J. , Nord Walter R. 
Published: April 2020

PurposeThis article assesses the ability of Boyer's (1990) four-function definition of scholarship to address critiques of business schools. Boyer's definition of scholarship is presented as the foundation for a paradigmatic shift in higher education in business.Design/methodology/approachThe authors developed this conceptual paper by considering information from three sources: 1) Ernest Boyer's Scholarship Reconsidered: Priorities of the Professoriate, 2) articles by four well-known pundits of business education as well as critiques appearing in the Academy of Management Learning and Education Journal and 3) articles in which Boyer's work was the focal point of the article found by searching Google Scholar, two well-known education journals, a prominent database of education articles and the International Handbook of Higher Education (Forest and Altbach, 2007).FindingsA four-function framework based on Boyer's definition of scholarship is proposed to help improve the operations of business schools. The authors also forward ideological and practical implications related to each of Boyer's four functions.Originality/valueFor several decades now, a number of highly respected business scholars have criticized American business education in its current form. These criticisms, although plentiful, have not fueled the magnitude of change needed to have a significant, sustainable impact on business education. The authors suggest that this lack of change is due, in part, to institutional practices and to the absence of a unified framework for how higher education in business should be executed. The authors argue that Boyer's four-function definition of scholarship could provide such a framework.
Perceptions and deeply held beliefs about responsibility for flood risk adaptation in Accra Ghana
Authors: Tasantab Jerry Chati , Gajendran Thayaparan , von Meding Jason , Maund Kim 
Published: April 2020

Purpose
Climate change is predicted to increase the vulnerability of urban populations to flood hazards. Against this backdrop, flood risk adaptation has become pertinent. However, in Ghana, current flood risk management practice is fostered by a reactive culture. There is limited research on how communities and government agencies are engaging with flood risk adaptation in improving resilience. Therefore, this paper aims to analyse the culture of communities and agencies through the cultural theory of risk (CTR), towards understanding the flood risk adaptation in Accra, Ghana. Culture is deciphered using the beliefs held by residents and public agency officials.

Design/methodology/approach
A qualitative methodology, underpinned by the constructivist paradigm, was adopted to understand factors that influence flood risk adaptation in informal settlements. Data was gathered using household and institutional interviews in Glefe, Accra, Ghana.

Findings
The results show that both disaster risk management institutions and community members are deeply concerned about current and future flood risk. However, their cultural beliefs concerning flood risk and adaptation are contradictory, broadly framed by fatalist, individualist and hierarchist beliefs. The contradictory emergent beliefs contribute to a clash of expectations and create uncertainty about how to respond to flood risk, impacting the implementation of required adaptation measures. Developing a collaborative flood risk management framework and a shared understanding of adaptation approaches may be a better alternative.

Originality/value
This paper advances understanding of how culture influences flood risk adaptation in developing country context.
A project buffer and resource management model in energy sector; a case study in construction of a wind farm project
Authors: Zohrehvandi Shakib , Vanhoucke Mario , Khalilzadeh Mohammad 
Published: April 2020

Purpose
This study aims to introduce an efficient project buffer and resource management (PBRM) model for project resource leveling and project buffer sizing and controlling of project buffer consumption of a wind power plant project to achieve a more realistic project duration.

Design/methodology/approach
The methodology of this research consists of three main phases. In the first phase of the research methodology, resource leveling is done in the project and resource conflicts of activities are identified. In the second phase, the project critical chain is determined, and the appropriate size of the project buffer is specified. In the third phase of the methodology, buffer consumption is controlled and monitored during the project implementation. After using the PBRM method, the results of this project were compared with those of the previous projects.

Findings
According to the obtained results, it can be concluded that using PBRM model in this wind turbine project construction, the project duration became 25 per cent shorter than the scheduled duration and also 29 per cent shorter than average duration of previous similar projects.

Research limitations/implications
One of the major problems with projects is that they are not completed according to schedule, and this creates time delays and losses in the implementation of projects. Today, as projects in the energy sector, especially renewable projects, are on the increase and also we are facing resource constraint in the implementation of projects, using scheduling techniques to minimize delays and obtain more realistic project duration is necessary.

Practical implications
This research was carried out in a wind farm project. In spite of the initial plan duration of 142 days and average duration of previous similar projects of 146 days, the project was completed in 113 days.

Originality/value
This paper introduces a practical project buffer and resource management model for project resource leveling, project buffer sizing and buffer consumption monitoring to reach a more realistic schedule in energy sector. This study adds to the literature by proposing the PBRM model in renewable energy sector.
Food insecurity status of the working poor households in south west Nigeria
Authors: Adesoye Oluwatimilehin Peter , Adepoju Abimbola Oluyemisi 
Published: April 2020

PurposeThe purpose of this paper is to examine the factors influencing the food insecurity status of the working poor households in south west Nigeria.Design/methodology/approachInternational Labour Organisation poverty line, Household Food Insecurity Access Scale as well as the Ordered Logit model were used to identify the factors influencing the food insecurity status of the working poor households in south west Nigeria.FindingsThe study revealed that more than half of the respondents were working poor households, with more than four-fifths of them being food insecure. Income irregularity, savings and level of education had major roles to play in the food insecurity status of working poor households.Social implicationsEmployment has always been considered as a route out of poverty and food insecurity. However, the intensity of poverty among working households should be considered in the design and development of policy and programmes, targeted towards workers. Laws should protect the right of workers against non-payment of salaries, advantages of family planning should be emphasised, social security allowance should be provided to serve as an alternative source of income during emergencies and more investment made in education.Originality/valueThis paper attempts to bridge the knowledge gap in the empirical link between employment, poverty and food insecurity. Particularly, its application to the working households.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/IJSE-09-2019-0589

Published: April 2020

PurposeThe aim of this study was to analyse the relationship between organizational citizenship and commitment in a sample of employees of banking branches in Puerto Rico. The specific objectives were to identify the practices of organizational citizenship and determine the relationship of altruism, awareness, courtesy, tolerance and civil virtue with organizational commitment.Design/methodology/approachThe research design was quantitative, descriptive, correlational and transversal. The research instrument was validated and obtained high coefficients.FindingsThe results confirm a significant statistical relationship between awareness, civil virtue, tolerance and altruism with organizational commitment.Research limitations/implicationsThis research has a positive impact on companies in increasing their finances with intangible strategies, and leadership styles can evolve towards civility. It suggests modifying the university curricula to prepare managers with intangible supervisory and performance management strategies through workshops, seminars and professional conferences.Practical implicationsOrganizations and employees develop their own traits and establish patterns of citizenship behaviour that allow them to create passionate and committed employees.Social implicationsThe research was able to predict that citizenship is related in a positive way to reach operational goals and fostering an atmosphere and image of cordiality as a success strategy. The contribution to the organizational policy can be established in the development processes among partners, in training, regulations and policies. It provides the academic contribution of the model.Originality/valueThis is the first attempt to evaluate citizenship behaviour in the banking industry in Puerto Rico.
