Molecular Imaging of Neuroendocrine Neoplasms
Authors: Refardt Julie , Hofland Johannes , Wild Damian , Christ Emanuel
Published: April 2022

The key for molecular imaging is the use of a radiotracer with a radioactive and a functional component. While the functional component targets a specific feature of the tumor, the radioactive component makes the target visible.

Neuroendocrine neoplasms (NEN) are a diverse group of rare tumors that arise from neuroendocrine cells found mainly in the gastroenteropancreatic system, lung, thyroid, and adrenal glands. They are characterized by the expression of specific hormone receptors on the tumor cell surface, which makes them ideal targets for radiolabeled peptides.

The most commonly expressed hormone receptors on NEN cells are the somatostatin receptors. They can be targeted for molecular imaging with various radiolabeled somatostatin analogs, but also with somatostatin antagonists, which have shown improved imaging quality. 18F-DOPA imaging has become a second-line imaging modality in NENs, with the exception of the evaluation of advanced medullary thyroid carcinoma.

Alternatives for NENs with insufficient somatostatin receptor expression due to poor differentiation involve targeting glucose metabolism, which can also be used for prognosis. For the localization of the often-small insulinoma, glucagon-like peptide-1 (GLP-1) receptor imaging has become the new standard. Other alternatives involve metaiodobenzylguanidine and the molecular target C-X-C motif chemokine receptor-4. In addition, new radiopeptides targeting the fibroblast activation protein, the glucose-dependent insulinotropic polypeptide receptor and cholecystokinin-2 receptors have been identified in NENs and await further evaluation.

This mini-review aims to provide an overview of the major molecular imaging modalities currently used in the field of NENs, and also to provide an outlook on future developments.

Context

Waist circumference (WC) is used in screening for metabolic syndrome (MetS) based on its association with cardiometabolic risk. This might apply differently in ethnically different populations. Associations with other measures are also unclear.

Objective

This work aimed to investigate the association between neck circumference (NC), WC, WC:hip circumference, WC:height (WC:Ht), NC:Ht, fat percentage, body mass index (BMI), conicity index, abdominal volume index, and weight-adjusted waist index with nonanthropometric components of MetS in nondiabetic Saudi adults.

Methods

This cross-sectional study took place in public health centers in Jeddah, comprising 1365 Saudi adults (772 men and 593 women) aged 18 years or older not previously diagnosed with diabetes.

Main outcome measures included

the presence of 2 or more nonanthropometric components of the MetS were used to define clinical metabolic abnormality (CMA). The predictive ability of studied anthropometric indices for CMA was determined using the area under receiver operating characteristics (AUC) curve and binary logistic regression.

Results

A total of 157 men and 83 women had CMA. NC and NC:Ht had the highest predictive ability for CMA in men (odds ratio [OR]NC = 1.79, P < .001 and ORNC:Ht = 1.68, P < .001; AUCNC = 0.69 [95% CI, 0.64-0.74] and AUCNC:Ht = 0.69 [95% CI, 0.64-0.73]). In women, WC had the highest predictive ability ORWC = 1.81, P < .001; AUCWC = 0.75 [95% CI, 0.69-0.80]).

Conclusion

Upper-body anthropometric indicators that were associated with subcutaneous fat had the highest predictive ability for CMA in men whereas abdominal obesity indictors had the best predictive ability in women, suggesting that fat distribution might contribute to CMA in a sex-specific manner.

Published: April 2022

BACKGROUND:

Encouraging early time of discharge (TOD) for medical inpatients is commonplace and may potentially improve patient throughput. It is unclear, however, whether early TOD after elective spine surgery achieves this goal without a consequent increase in re-presentations to the hospital.

OBJECTIVE:

To evaluate whether early TOD results in increased rates of hospital readmission or return to the emergency department after elective anterior cervical spine surgery.

METHODS:

We analyzed 686 patients who underwent elective uncomplicated anterior cervical spine surgery at a single institution. Logistic regression was used to evaluate the relationship between sociodemographic, procedural, and discharge characteristics, and the outcomes of readmission or return to the emergency department and TOD.

RESULTS:

In multiple logistic regression, TOD was not associated with increased risk of readmission or return to the emergency department within 30 days of surgery. Weekend discharge (odds ratio [OR] 0.33, 95% CI 0.21-0.53), physical therapy evaluation (OR 0.44, 95% CI 0.28-0.71), and occupational therapy evaluation (OR 0.32, 95% CI 0.17-0.63) were all significantly associated with decreased odds of discharge before noon. Disadvantaged status, as measured by area of deprivation index, was associated with increased odds of readmission or re-presentation (OR 1.86, 95% CI 0.95-3.66), although this result did not achieve statistical significance.

CONCLUSION:

There does not appear to be an association between readmission or return to the emergency department and early TOD after elective spine surgery. Overuse of inpatient physical and occupational therapy consultations may contribute to decreased patient throughput in surgical admissions.

Published: April 2022

BACKGROUND:

Dural arteriovenous fistulas (dAVFs) are often treated with stereotactic radiosurgery (SRS) to achieve complete obliteration (CO), prevent future hemorrhages, and ameliorate neurological symptoms.

OBJECTIVE:

To summarize outcomes after SRS for dAVFs and propose relevant practice recommendations.

METHODS:

Using a PICOS/PRISMA/MOOSE protocol, we included patients with dAVFs treated with SRS and data for at least one of the outcomes of the study. Relevant outcomes were CO, symptom improvement and cure, and post-SRS hemorrhage or permanent neurological deficits (PNDs). Estimated outcome effect sizes were determined using weighted random-effects meta-analyses using DerSimonian and Laird methods. To assess potential relationships between patient and lesion characteristics and clinical outcomes, mixed-effects weighted regression models were used.

RESULTS:

Across 21 published studies, we identified 705 patients with 721 dAVFs treated with SRS. The CO rate was 68.6% (95% CI 60.7%-76.5%) with symptom improvement and cure rates of 97.2% (95% CI 93.2%-100%) and 78.8% (95% CI 69.3%-88.2%), respectively. Estimated incidences of post-SRS hemorrhage and PNDs were 1.1% (95% CI 0.6%-1.6%) and 1.3% (95% CI 0.8%-1.8%), respectively. Noncavernous sinus (NCS) dAVFs were associated with lower CO (P = .03) and symptom cure rates (P = .001). Higher grade was also associated with lower symptom cure rates (P = .04), whereas previous embolization was associated with higher symptom cure rates (P = .01).

CONCLUSION:

SRS for dAVFs results in CO in the majority of patients with excellent symptom improvement rates with minimal toxicity. Patients with NCS and/or higher-grade dAVFs have poorer symptom cure rates. Combined therapy with embolization and SRS is recommended when feasible for clinically aggressive dAVFs or those refractory to embolization to maximize the likelihood of symptom cure.

Published: April 2022

Development and progression of chronic kidney disease (CKD) in patients with renal cell carcinoma (RCC) after radical nephrectomy remains an extremely pressing contemporary issue.

Postoperative changes of the ultrasound resistance index (RI) in the contralateral kidney not affected by the tumor after surgical treatment of RCC, as well as correlations between changes in IR and in glomerular filtration rate (GFR) remain far from being comprehensively investigated.

The RI changes in the parenchyma of the intact (unaffected by the tumor) kidney before and after surgical treatment for RCC, and establishing correlations between RI changes and creatinine-dependent GFR remain unexplored issues.

Objective. To assess the correlation between RI and GFR in the kidney not affected by the RCC before and after radical nephrectomy.

Materials and methods. The study enrolled 49 patients. Group I included 37 patients with an initial diagnosis of RCC (on the right), Stage III of the disease, and without signs of chronic renal failure (GFR was ≥ 90 ml/min/1.73 m2).

In patients with RCC, six months after surgery, the RI increase in the contralateral kidney unaffected by the tumor was significantly associated with a significant reduction in GFR. Thus, RI can be potentially used to predict the development of CKD in this patient population.
The Health Problems of Polish and Lithuanian Youth During the Period of Remote Education of the COVID-19 Pandemic
Authors: Przybysz-Zaremba Małgorzata , Polok Krzysztof
Published: April 2022

The COVID-19 pandemic resulted in numerous changes and restrictions in many countries around the world, including school closures. Remote learning was introduced and took place on various online platforms. The aim of the presented study was to determine the health problems experienced by Polish and Lithuanian youth during the period of remote education which was enforced by the outbreak of the COVID-19 pandemic. The study used a proprietary questionnaire and 385 students aged 13–16 from Polish and Lithuanian schools participated in the study. Polish and Lithuanian youth experienced many health problems, but the dominant ones were the following: headaches, backaches, problems with concentration, sleep problems and nervousness. These were health problems that resulted from young people sitting for long hours in front of a computer monitor and participating in remote education. The passive and (often incorrect) seating posture adopted by the students and direct contact with the computer and/or the Internet led to the occurrence of many health problems and disorders in both Polish and Lithuanian youth.

Authors: Wójcik Anna
Published: April 2022

Artykuł ma na celu przedstawienie koncepcji dobrostanu subiektywnego (szczęścia) jako propozycji dla przyszłych nauczycieli przedszkolnych i wczesnoszkolnych do stosowania w procesie wychowania do wartości. Autorka stawia tezę, że konieczne jest zdefiniowanie i zrozumienie przez studentów dobrostanu subiektywnego oraz osiągnięcie świadomości, że nauczyciel w polskiej placówce oświatowej jest zdany na samodzielną profilaktykę w tym zakresie w celu kreowania pozytywnego wzorca osobowego. W artykule zwrócono uwagę na konieczność codziennej, systematycznej oraz długoterminowej troski o dobrostan subiektywny w celu zakorzenienia się nawyku samokontroli. Efektywność działań podejmowanych z uczniami jest powiązana z subiektywnym dobrostanem nauczyciela, który nie przekazuje wyłącznie informacji, ale jest wzorem do naśladowania w zakresie nauki wartości społecznych i poznawczych.
PRESENCIAS LITERARIAS, AUSENCIAS HISTÓRICAS: RESCATANDO FIGURAS FEMENINAS DEL PASADO DE LA MANO DE ESCRITORAS ITALIANAS
Authors: Ferrer María Reyes
Published: April 2022

En el presente estudio se abordará el tema de la novela histórica italiana desde una perspectiva que ha sido –y es- escasamente reconocida en los estudios literarios, esto es, “femenina”. El resultado de la incorporación de la mujer a la narrativa histórica supone un evidente distanciamiento, en ciertos aspectos, de la novela histórica tradicional ya que, por un lado, se cuestiona la validez de la historiografía tradicional al hacer evidente la falta de la presencia femenina y, por otro, se exige la creación de un espacio propio dentro de la historia a través de las formas literarias. Así, a finales de los años sesenta, y coincidiendo con el empuje del movimiento feminista, las mujeres comienzan a luchar por construir su lugar en la historia y en la literatura, donde poco a poco puedan ir reconociéndose como sujetos históricos, siempre presentes y, por lo tanto, dignos de estudio. Palabras claves: Novela histórica femenina, mujeres, espacio, escritoras.

HUELLAS DE AUTOBIOGRAFÍA EN LAS NOVELAS DE MERCÈ RODOREDA
Authors: Veglia Laura
Published: April 2022

Mercè Rodoreda expresa en su obra una fuerte identidad catalana y una identidad femenina contra corriente. La autora, desde su exilio en Ginebra, donde se establece en 1954 y donde vivirá veinte años, sigue escribiendo en su lengua: el catalán. Esta elección es el resultado de una defensa identitaria y cultural que Rodoreda lleva a cabo a lo largo de toda su vida. En este informe quiero analizar las huellas autobiográficas que se encuentran en sus novelas del exilio: las protagonistas de sus obras huyen de toda definición identitaria, como lo hizo ella durante su vida. Sus obras están ambientadas en los lugares donde ella ha vivido: Barcelona, Ginebra, Romanyá de la Selva, y el exilio mismo atraviesa toda la obra rodorediana, hasta el punto que, más de treinta años después de su primera publicación, vuelve a escribir una de sus novelas de la época anterior al exilio: Aloma.

L’ASSENZA ‘‘PRESENTE’’ DI GEORGE ELIOT: FRA CENTRO INGLESE E MARGINE MEDITERRANEO
Authors: Cazzato Luigi
Published: April 2022

Il saggio si cimenta con la questione dell’assenza di George Eliot come autoredonna sulle scene letterarie. La romanziera inglese scelse di celare il proprio genere sotto uno pseudonimo maschile, apparentemente, per poter affrontare nel suo centro ciò che è stato chiamato “the regime of the male gaze”. Questo suo atto, considerato ambiguo dalla critica femminista, può dirci qualcosa, non solo in relazione a questioni di posizionamento di genere, ma anche in relazione a questioni di posizionamento di ciò che nel suo secolo veniva chiamata “razza”. In altre parole, il saggio si occupa, dal punto di vista postcoloniale, dei suoi rapporti di autrice al centro della cultura patriarcale metropolitana con i margini mediterranei (Italia e Spagna) orientalizzati, ovvero meridionizzati, che lei visitò durante i suoi viaggi e di cui scrisse nelle sue lettere e nei suoi romanzi. Parole chiave: Scrittura femminile, sguardo maschile, Mediterraneo, meridionismo

La alianza existente en la tradición occidental entre mitos y estereotipos sobre lo femenino exige el examen de algunas de las consecuencias emocionales de esa mirada masculina y colonial, que aniquiló la civilización azteca. La invención de las mujeres serpiente inspiró los más devastadores mitos públicos de Medusa y Eva, teorizando y dando forma (serpiente y mirada homicida) a la alteridad desde la antigüedad hasta el siglo XVI y más allá. El análisis reflexiona sobre los usos pragmáticos del imaginario de alteridad femenina y su repercusión en mesoamericanas culturas, a través del ejemplo de la diosa azteca Coatlicue. Palabras claves: imaginario colonial, educación pública, mujeres serpiente, emociones negativas.
FRAGMENTOS DE VIDA: LA PROSA DE ADA NEGRI
Authors: Cagnolati Antonella
Published: April 2022

Las huellas del género autobiográfico proliferan de forma abundante en las obras que intentan reflexionar con una mirada nueva sobre los acontecimientos relacionados con las vidas de las mujeres: entre los años ochenta del siglo XIX y los años veinte del siglo XX en Italia son numerosos los testimonios que intentan legitimar las alternativas, a veces en contra de la tendencia, respecto al habitus compartido y aceptado por la moral burguesa y las normas comportamentales que la hipocresía social predica como valores sobre los cuales marcar la existencia. Ada Negri acampa en este fértil movimiento, como una hábil y aguda observadora de la existencia de las mujeres: se coloca, sin duda, del lado de las mujeres que sufren, las escudriña y pone de manifiesto la vileza de los comportamientos sociales que imponen atenerse rigurosamente a normas comportamentales determinadas e impuestas por la cruel maldad del patriarcado.

ZENOBIA CAMPRUBÍ: LA SUBJETIVIDAD EN EL DISCURSO POÉTICO DE UNA AUTORA FUERA DEL CANON LITERARIO
Authors: Ojea Fernández María Elena
Published: April 2022

Nuestro artículo tiene como objetivo analizar el discurso poético de Zenobia Camprubí, intelectual española, conocida por ser esposa y musa del poeta Juan Ramón Jiménez. Nuestra propuesta indaga tanto en su imagen de esposa abnegada, encadenada a la larga sombra de Juan Ramón, como en la delicadeza y la expresividad casi espontánea de sus versos, de los que emerge un tono melancólico que no solo hace entrever la poesía como alivio sino que ese mismo matiz ayuda a representar la propia historia alejada de la mística femenina tradicional. Su discurso poético es una habitación propia que teje una relación de interdependencia entre el mundo y la palabra. La autora expresa poéticamente su subjetividad, con elegancia, sin afectación, haciendo gala de un lenguaje sencillo que refleja su identidad literaria y su metafísica particular. Palabras claves: discurso poético, subjetividad, presencia, ausencia, canon.

A Classifier to Decide on the Linearization of Mixed-Integer Quadratic Problems in CPLEX
Authors: Bonami Pierre , Lodi Andrea , Zarpellon Giulia
Published: April 2022

Despite modern solvers being able to tackle mixed-integer quadratic programming problems (MIQPs) for several years, the theoretical and computational implications of the employed resolution techniques are not fully grasped yet. An interesting question concerns the choice of whether to linearize the quadratic part of a convex MIQP: although in theory no approach dominates the other, the decision is typically performed during the preprocessing phase and can thus substantially condition the downstream performance of the solver. In “A Classifier to Decide on the Linearization of Mixed-Integer Quadratic Problems in CPLEX,” Bonami, Lodi, and Zarpellon use machine learning (ML) to cast a prediction on this algorithmic choice. The whole experimental framework aims at integrating optimization knowledge in the learning pipeline and contributes a general methodology for using ML in MIP technology. The workflow is fine-tuned to enable online predictions in the IBM-CPLEX solver ecosystem, and, as a practical result, a classifier deciding on MIQP linearization is successfully deployed in CPLEX 12.10.0.
Establishing consensus on the appropriate selection of continence pads to achieve optimal care while reducing the risk of harm: part of a holistic approach for people with incontinence
Authors: Orme Susie , Yates Ann , Fortes-Mayer Gail , Reynolds Lindsay , Vickerman Julie , Fordham Sally , Robinson Jacqueline
Published: April 2022

Background/Aims

Continence conditions are a widespread and prevalent issue within the UK. However, provision of continence products are not distributed on an equitable basis across the country and often do not take into account patient-centric factors, such as quality of life and physical needs. The aim of this study was to establish the level of agreement held by UK healthcare professionals around the provision and selection of continence products and identify any areas where recommendations could be proposed to reduce harm to patients in relation to quality of life, mental health, skin health and patient wellbeing through the right choice of continence product.

Methods

A steering group of incontinence experts identified 50 statements impacting continence care. From this, an online survey was developed and respondents from across the UK were invited to rate their agreement with each statement. A modified Delphi methodology was used to review responses, with a threshold for consensus agreement set at 66%.

Results

A total of 181 responses were received. Overall, 39 out of 50 statements achieved very high consensus agreement (≥90%), nine statements achieved high consensus agreement (between 66% and 90%) and two statements did not achieve the consensus threshold but were over 60%.

Conclusions

The results demonstrated clear support among respondents for making improvements that focus on meeting the individual needs of the patient, which includes accurate, comprehensive continence assessment and product provision and mental health aspects, rather than budgetary concerns.

Utility Financing of Energy Projects
Authors: McGeown David I.
Published: April 2022

Proposals to deregulate the electric industry have created a tre-mendous surge of activity. Utility planners are busy creating new andexciting businesses for this competitive future. ''Value-added service"is the catch phrase in most plans .Many utilities are reeling under the impact of these proposals,but a caution, they have yet to arrive! Some view the future withexcitement , others with trepidation, a few of our colleagues with gloomas they look for a job.The transformation that is about to happen in the utility industrywill happen regardless of regulatory influences. Customer s are alreadydemanding more services. Their expectations have been set.Customers expect to be provided with the most competitive com-binati on of energy sources and technologies for their business . Newcompanies are being formed daily to meet this need. Specializing inhelping the owners and operators of buildings to cost effectively man-age energy consumption, energy service providers offer a wide portfolioof services. These range from a relatively simple, or so it may seem,commodity to very complex outsourcing deals. The mission is to winand r etain customers .Often these customers will not have to deal with kilowatt-hoursor therms. Services will be purchased as end uses like cooling andlighting. Which bring us pretty much back to where it all started.Thoma s Edison's original vision was for the supply of lighting, notelectricity.
Is There a Future for IPPs?
Authors: Hyman Leonard S.
Published: April 2022

Technology made the old system. Technology will kill the oldsystem. For eight decades, electric utilities ran unchallenged naturalmonopolies, because they possessed economies of scale. No organiza-tions could produce electricity at lower cost than those monopolies .Operating economies increased steadily. The utility, not only moreefficient than erstwhile competitors, grew more efficient over time .Cl)Circa 1960, conventional power stations reached the efficiencylimits imposed by the Rankine Cycletz), a necessary but not sufficientreason to declare the natural monopoly dead . Utilities, after all, stillprovided the lowest cost service. Nobody else could undercut them .About the same time, electrical equipment manufacturers beganto sell gas turbines as stationary power sources. Most utilities did nottake seriously the new technology. Of course the Big Three did not takethe first Toyotas seriously either, probably for the same reasons: tinnystuff with a limited market .After much R&D work, manufacturers developed clean, low-cost,reliable gas turbines . The same manufacturers that produced genera-tion after generation of increasingly efficient conventional steam gen-erators proceeded to do the same with gas turbines, except on a moreaccelerated schedule. Eventually, those small, modular, clean, factory-made gas turbines could produce electricity at a lower cost than that ofthe larger units of many utilities.

Thermal Tracking Cogeneration- A New or Old Idea? Cogeneration for Multi-Thermal Loads
Authors: Geers James R.
Published: April 2022

The concept of cogeneration has been around for decades. Euro-pean communities have been successfully using the idea for manyyears . The idea of designing a cogeneration project that produceselectricity based on the existing heating load is common to manycogeneration projects, but may be limiting the ultimate potential tothe end user . Cogeneration which is developed as a power generatorproducing a small amount of steam for a host load is also common.However, the idea of designing a cogeneration facility to track mul-tiple utility loads is not as common. Where the concept has been used ,the projects have been very successful.After decades of excellent books, articles, and conferences, manyenergy professionals still focus their effort on the heating loads. Theyevaluate this one factor to determine if a project is worthy of seriousconsideration . What has been amazing is the lack of expertise andknowledge of multiple load evaluations . The thermal loads includeboth steam and high temperature hot water used for heating, chilledwater for air conditioning, refrigeration, process, compressed air andother special uses . In many cases, the overall benefit to the projectown er and host tenant far exceeds the increase in the capital costs.This article has been written as a primer for professionals look-ing for ideas when performing analysis of a potential cogenerationproj ect, and as a thought -provoker for end users . We will look at eachof the possible loads, outline various technical considerations andfact ors, look at the factors impacting the economics, and layout anapproach that would provide assistance to those trying to analyze acog eneration project without specialized engineering assistance .R egulat ory , legal and financing issues are covered in other sources .

Non-private Power Aggregation: New Markets for Public-private Partnerships
Authors: Feldman Roger D.
Published: April 2022

The emergence of privately sponsored customer aggregationfirms aimed principally at the private market in response to electricpower deregulation was an obvious development, following the pat-tern set first in natural gas. Aggregators-whether independent, orassociated with power marketers or ESCOs-bring with them notonly the capability to enhance composite purchase power muscle, butto provide to aggregation customers valuable system planning inter-mediary services to structure lower overall costs, by, for example,better matching usage requirements .The emergence of "non-private" aggregators in the public andthe not-for-profit sector has not received as much attention, becausethose fields generally have been viewed as additional markets for theprivate sector rather than themselves entrepreneurial initiators ofchange. That viewpoint overlooks a salient fact : deregulation threat-ens these sectors themselves with privatization unless they respondproactively themselves.
