Authors: El-Ghazaly Tamer E. , Abdelazim Ibrahim A. , Elshabrawy A. 
Published: September 2022

Objectives:
Many women experience pain and discomfort after hysteroscopic procedure. Pain and discomfort after hysteroscopic procedures can be explained by the cervical dilatation, intrauterine manipulation, and/or hydrodistension. This study designed to evaluate the efficacy of intrauterine levobupivacaine instillation for pain control in women undergoing diagnostic hysteroscopy.

Materials and Methods:
One hundred and twenty (120) women scheduled for diagnostic hysteroscopy and endometrial biopsy due to uterine bleeding were included in this study and randomized either to levobupivacaine group or controls. At the end of hysteroscopy, 5 mL of 0.5% levobupivacaine was instilled intrauterine in levobupivacaine group, while 5 mL of 0.9% saline was instilled intrauterine in controls. Participants were kept in the hospital for 12 h after diagnostic hysteroscopy to detect the postoperative (PO) pain intensity using visual analog scale (VAS), and PO required analgesics.

Results:
The VAS was significantly lower in levobupivacaine group compared to controls 3 h. PO (1.31 ± 1.02 vs. 1.62 ± 0.76, respectively), (P = 0.01), 6 h. PO (0.81 ± 1.24 vs. 1.53 ± 0.88, respectively), (P = 0.004), and 9 h. PO (0.55 ± 1.25 vs. 1.12 ± 0.95, respectively), (P = 0.01). The total PO required analgesics were significantly lower in levobupivacaine group compared to controls (P = 0.005).

Conclusion:
The intrauterine levobupivacaine instillation was simple, and effective for pain relief after diagnostic hysteroscopy, it significantly decreased pain score assessed by VAS at 3, 6, and 9 h., PO, and it significantly decreased PO required analgesics.

Published: September 2022

Background and Aims:
This study describes the functional analysis of a negative pressure canopy unit developed to reduce infective aerosol and droplet spread in ad-hoc wards created to handle patients suffering from infective respiratory illnesses such as those recently encountered in the COVID-19 pandemic.

Methods:
An experimental study was conducted to verify the functional analysis of a canopy unit for the following variables: a) Quantitative and qualitative analysis of aerosol generation, b) Efficacy of canopy as containment device and c) Aerosol clearance from canopy over a period. We describe the process in the form of a problem statement, a discussion of design considerations (including Computer Aided Design modelling and a functional analysis of the system using a variety of simulated conditions which included various experiments for the purpose of testing the safety and efficiency of the system. We also incorporated Computational Fluid Dynamics analyses to assist us in design modifications of the unit using Euler-Lagrange approach for aerosol tracking.

Results:
As demonstrated by the series of experiments, it was seen that the aerosol load under the testing conditions reduced significantly. The canopy unit restricted the aerosol particles which either got adhered to the canopy walls or went into recirculation inside the canopy. In experimental conditions, the fan-filter unit was able to operate at >95% efficiency.

Conclusion:
This device exhibited 95–99% efficiency in eliminating aerosols which would reduce the exposure of health care workers to infective aerosols, which is not only specific to severe acute respiratory syndrome coronavirus (SARS-CoV)-2, but also to other airborne transmitted diseases.
A randomised controlled trial of high-flow nasal oxygen versus non-rebreathing oxygen face mask therapy in acute hypoxaemic respiratory failure
Authors: Thota Bhargavi , Samantaray Aloka , B Vengamma , Mangu Hanumantha Rao , Alladi Mohan , Kalawat Usha 
Published: September 2022

Background and Aims:
A major limitation to providing oxygen therapy by high flow nasal oxygen (HFNO) delivery devices is its availability and therefore as an alternative many clinicians use a standard non rebreathing face mask (NRBM) in order to oxygenate their patients where low-flow nasal oxygen or simple facemask oxygen is not providing adequate respiratory support to achieve the target peripheral oxygen saturation (SpO2). We aimed to determine the clinical effectiveness of HFNO versus NRBM in terms of improving patient outcome among patients admitted to our intensive care unit (ICU) during coronavirus disease-2019 (COVID-19) outbreak.

Methods:
In this prospective open labelled study, 122 COVID-19 patients presenting with acute hypoxaemic respiratory failure (AHRF) were randomised to receive either HFNO or NRBM to achieve the target SpO2. The primary clinical outcome measured was device failure rate and secondary outcome was all-cause 28-day mortality rate.

Results:
The device failure rate was significantly higher in HFNO group (39% versus 21%, P = 0.030). Oxygen support with NRBM resulted in a reduced all mortality rate over HFNO (26.2% versus 45%) but the mortality rate after treatment failure in either group (HFNO or NRBM) remained high (91% versus 92%).

Conclusion:
Oxygen support with NRBM results in both reduced device failure rate and higher survival among patients of COVID-19 with AHRF.

Published: September 2022

Background:
Approximately 5% of COVID-19 patients suffer from near-fatal disease. Clinical and radiologic features may predict severe disease although with limited specificity and radiation hazard. Laboratory biomarkers are specific, simple, and point-of-care triage tools that can be used to predict the severity of the disease. This research aimed to study the role of inflammatory markers (serum ferritin, lactate dehydrogenase [LDH], D-dimer, and C-reactive protein [CRP]) in prognosticating COVID-19 patients.

Methodology:
This was a hospital-based retrospective study conducted on COVID-19 adult inpatients classified into three groups: mild disease-recovered (Group I), severe disease-recovered (Group II), and dead (Group III). Categorical outcomes were compared using the Chi-square test. Univariate binary logistic regression analysis was performed to test the association between the outcome and explanatory variables. An unadjusted odds ratio (OR) along with a 95% confidence interval was calculated. The utility of laboratory parameters (ferritin, LDH, neutrophil/lymphocyte ratio, D-dimer, and platelet/lymphocyte ratio) in predicting the severity of COVID-19 was assessed by the receiver operative curve analysis. P < 0.05 was considered statistically significant.

Results:
A total of 500 case records were analyzed. The mean age was 49.32 ± 17.1 years. About 72.4% were <60 years and 301 male and 199 female patients were included. The comorbidity count included diabetes 168 (33.6%), hypertension 122 (24.4%), coronary artery disease 23 (4.6%), hypothyroidism 3 (6%), and others 33 (6.6%) The median levels of ferritin among the three groups differed significantly bearing higher levels in Group 3 (P < 0.001). Median LDH and D-dimer values of the three groups showed statistical significance (P < 0.001). Qualitative CRP was significantly associated with poor outcomes (P < 0.001). The odds of patients suffering severe COVID-19 rose with rising values of ferritin, LDH, and D-dimer (unadjusted OR: 1.007, 1.004, and 1.020).

Conclusion:
Onetime measurement of serum ferritin, LDH, D-dimer, and CRP performed between 7th and 10th day of symptoms significantly predicted outcomes for COVID-19 inpatients.
Joint resource optimization for nonorthogonal multiple access‐enhanced scalable video coding multicast in unmanned aerial vehicle‐assisted radio‐access networks
Authors: Tong Ziyuan , Shen Hang , Shi Ning , Wang Tianjing , Bai Guangwei 
Published: September 2022

AbstractA joint resource‐optimization scheme is investigated for nonorthogonal multiple access (NOMA)‐enhanced scalable video coding (SVC) multicast in unmanned aerial vehicle (UAV)‐assisted radio‐access networks (RANs). This scheme allows a ground base station and UAVs to simultaneously multicast successive video layers in SVC with successive interference cancellation in NOMA. A video quality‐maximization problem is formulated as a mixed‐integer nonlinear programming problem to determine the UAV deployment and association, RAN spectrum allocation for multicast groups, and UAV transmit power. The optimization problem is decoupled into the UAV deployment–association, spectrum‐partition, and UAV transmit‐power–control subproblems. A heuristic strategy is designed to determine the UAV deployment and association patterns. An upgraded knapsack algorithm is developed to solve spectrum partition, followed by fast UAV power fine‐tuning to further boost the performance. The simulation results confirm that the proposed scheme improves the average peak signal‐to‐noise ratio, aggregate video‐reception rate, and spectrum utilization over various baselines.

Published: September 2022

The Itaparica region located between Pernambuco and Bahia had got part of his territory flooded due to the construction of the reservoir of the Luiz Gonzaga Hydroeletric, built in 1988. About 10,500 families were transferred to resettlement areas as result of the reservoir construction. More than 21,000 people lived in urban areas and more than 19,000 in rural areas. The resettlement were used construct new cities and areas with irrigated settlements and small villages (agrovilas). The resettlements of Apolônio Sales, Icó-Mandantes and Barreiras Bl2 are the oldest in the Petrolândia Municipality, only the first present different infrastructure. This research aims to discuss the challenges in land management of the irrigated schemes of Chesf in Petrolândia after the Itaparica reservoir construction. Field works, including interviews and workshops using the Constellation Analysis methodology was used as tool in the elaboration of this study. Currently the agrovilas are with an outdated water supply and treatment system most likely causing health issues for the resettled people. The agrovila area presents a disorderly urban increase, normally caused because of immigrants who came to the irrigated scheme to work in the farming or to invest in the agriculture. They also expand new irrigated schemes through inappropriate areas, leaving residential garbage in the native vegetation and using water uncontrolled, causing reduction in the water supply. The debate over the water and land access and the effective action of the public power together with the producers are urgent to solve the existing problems in the resettlements.
PEIXES-BOIS DAS PRAÇAS DO RECIFE – A HISTÓRIA DE UM SÉCULO DE CONVÍVIO E ADMIRAÇÃO DOS PERNAMBUCANOS A ESTES ANIMAIS
Authors: Luna Fabia Oliveira , Attademo Fernanda Loffler Niemeyer 
Published: September 2022

A ocorrência do peixe-boi marinho no Brasil é registrada desde o período da colonização do país. A caça desses animais ocasionou a redução do tamanho das populações e a extinção em algumas regiões, como parte do litoral de Pernambuco. No passado, as cidades de Olinda e Recife apontam que o uso do peixe-boi como fonte de alimento, podendo ser o motivo pela ausência de avistagem da espécie no litoral desses municípios. Essa teria sido a primeira principal relação entre recifenses e os peixes-bois. Após praticamente três séculos, os recifenses voltam a ter uma forte relação com os peixes-bois, quando animais passam a viver em tanques de praças e parques públicos da cidade. A sociedade começou a admirá-los em momentos de lazer, sendo uma atração das tardes dos domingos. Esse ciclo de animais cativos e visitação pelos pernambucanos e turistas de outras regiões durou mais de um século, com início em 1909, quando Chico chegou a Praça da República, e teve seu fechamento em 2015, mas permaneceu na Ilha de Itamaracá e na memória dos pernambucanos. Dentre os peixes-bois das praças, Xica, foi o mais visitado, tendo sido considerada uma “celebridade” e até mascote da cidade do Recife.

Este texto é resultado da pesquisa de iniciação cientifica desenvolvida no Assentamento Ireno Alves dos Santos, município de Rio Bonito do Iguaçu, Estado do Paraná. O objetivo foi levantar as políticas públicas acessadas pelos assentados e seus impactos para a economia familiar. A pesquisa apoiou-se na experiência concreta de assentamento, já que a acadêmica autora deste trabalho é moradora do local, o que permitiu levantar informações fidedignas sobre quais são as políticas públicas acessadas por esses sujeitos, bem como avaliar as mudanças ocorridas no município de Rio Bonito do Iguaçu, Paraná, depois da criação do Assentamento Ireno Alves dos Santos, em 30 de outubro de 1997. A metodologia integrou duas etapas: no um primeiro momento realizou-se revisão teórica, tratando de esclarecer os principais conceitos do trabalho, ou seja, compreender o que são políticas públicas, agricultores familiares e assentados da reforma agrária. Foi possível conhecer parte do debate sobre essas temáticas, os sujeitos envolvidos, e especificamente compreender, via dialogo com os assentados, quais políticas públicas eles acessavam e a realidade desses trabalhadores. A pesquisa evidenciou que grande parte dos assentados entrevistados não tinha acesso a políticas públicas.

Descriptive statistics revealed decreases in the average percentages of White teachers and of White students in Texas public elementary school over 9 school years of data examined herein. The average percentages of Asian, Black, and Hispanic student and teachers increased from 2010-2011 to 2018-2019. Through comparisons of the ethnic/racial diversity of teachers and of students, clear disparities were evident. Higher percentages of White teachers were present than percentages of teachers of color and percentages of students of color. Implications for policy and for practice, as well as recommendations for future research, were discussed.
Bishop, Kepler and Sarduy: Ellipse and Ellipsis
Authors: Cheema Amna Umer 
Published: September 2022

Abstract
This article expands on Elizabeth Bishop’s affinity with the Cuban poet and critic Severo Sarduy and his neo-baroque reading of the seventeenth-century mathematician and astronomer Johannes Kepler’s planetary geometry of the imperfect circle called the ellipse and its linguistic equivalent the ellipsis (Sarduy 293). This essay will elucidate the geometrical decentering of space and the linguistic decentering of meanings as characteristics of ellipse and ellipsis through a discussion of Bishop’s poems, “In the Waiting Room,” “The Bight” and “One Art.” I argue that Bishop’s engagement with ellips(e/is) is a spatial response to the destabilization of modern urban space and the gap between language and signification, akin to T.S. Eliot’s ideas about the gap between thought and feeling in modern sensibility. Through ellips(e/is), Bishop seeks a perspective outside definitive contours and finds beauty in an incomplete and distorted embodiment of an ever-becoming truth.
