Exploratory study of a system to reduce information overload and tunnel vision in homicide investigations
Authors: Vredenborg Marloes , Sutmuller Daan , den Hengst-Bruggeling Mariëlle , Masthoff Judith
Published: August 2022

In homicide investigations, the growing availability of data results in an increasing amount of information and Persons of Interest (PoIs) that can be collected and incorporated during an investigation. This might result in information overload and increased tunnel vision during a homicide investigation. In this paper, we designed a system to support homicide investigations in such a way that it reduces information overload and tunnel vision. For evaluation purposes, we built a prototype that was filled with a fictional homicide investigation. A user study indicated that criminal investigators experienced a significantly low level of information overload and tunnel vision using the prototype. Moreover, the results showed acceptable usability and verbal statements indicated a largely positive attitude towards the prototype. This research clearly shows the opportunity to use interface design artefacts to support the prevention of information overload and tunnel vision.
Embedded Epistemic Instrumentalism: An Account of Epistemic Normativity
Authors: Willoughby James Bernard
Published: August 2022

We are bombarded with epistemic norms. Respect your evidence. Don’t believe in contradictions. Don’t arbitrarily change beliefs. But how do such norms get their normative force? Why should we respect our evidence, for example?  In this paper I offer a familiar type of answer, epistemic instrumentalism. Epistemic instrumentalism holds that epistemic norms get their normative force by being useful. You should respect your evidence because it will help you achieve some valuable ends. This answer, while familiar, is not very popular. There is a widely accepted objection to epistemic instrumentalism, the too few reasons objection. The objection looms so large that standard developments of instrumentalism have become bloated with philosophical machinery to respond to it. This does a disservice to epistemic instrumentalism. Rather than focusing completely on the objection, I focus on describing a simple model for how conforming to the epistemic norms is broadly useful. Once I describe the simple model, the too few reasons objection becomes much easier to answer. This strategy results in a well-motivated philosophical theory based on uncontroversial facts that has many advantages over rival theories.

Authors: Sabzevari Fateme , Mogharnasi Mehdi , Golestani Fateme
Published: August 2022

Background:

This study aimed to investigate the effect of 6 weeks’ pilates training along with dill supplementation on serum concentrations of nesfatin-1, lipocaline-2, and insulin resistance in females with overweight and obesity.

Materials and Methods:

In this randomized controlled trial study, 45 overweight and obese females are randomly assigned to four groups: Pilates training + dill group (PDG) (n = 12), pilates training + placebo group (PPG) (n = 11), dill supplementation group (DG) (n = 11), and placebo group (PG) (n = 11). Participants of PDG and PPG performed pilates training for 6 weeks (60 min, 3 sessions per week). PDG and DG received dill tablet (three times a day, 6 weeks). Anthropometric measurements, glycemic markers, and blood samples were assessed before (pretest) and after (posttest) 6 weeks of intervention.

Results:

Results showed a significant increase in serum concentrations of nesfatin-1 in PDG compared to pretest (P = 0.001). Differences in the serum concentrations of nesfatin-1 in PDG were greater than PPG, DG, and PG (P = 0.01). Furthermore, results found in significant reduction in serum concentrations of lipocalin-2, body mass index (BMI), and waist-hip ratio (WHR) in PDG, PPG, and DG as compared to pretest (P > 0.05). Fasting glucose plasma (FGP) was significantly decreased in all three intervention groups PDG (P < 0.001), PPG (P < 0.001), and DG (P < 0.001) as compared to pretest. Differences in FGP were significantly higher in PDG than PPG, DG, and PG (P = 0.001). A significant reduction was found for insulin only in PDG after 6 weeks of intervention as compared to pretest (P = 0.03). Insulin resistance significantly decreased in PDG (P = 0.03) and PPG (P = 0.04) as compared to pretest. Body fat percent (BFP) was significantly decreased in PDG (P = 0.003), PPG (P = 0.006), and DG (P = 0.01). However, there were no significant inter-group differences in insulin resistance, insulin, serum concentrations of lipocalin-2, BMI, BFP, and WHR after 6 weeks of Pilates training along with dill supplementation (P > 0.05).

Conclusion:

We concluded that 6 weeks of Pilates training along with dill may be beneficial for improvements in serum concentrations of nesfatin-1 and FGP.
Bilateral Female Inguinal Hernia Repair in Margaret Marquart Catholic Hospital and Review of Literature
Authors: Ali Mahamudu Ayamba , Abedi Emmanuel , Hagbevor Israel , Kyei Mathew Y
Published: August 2022

Background:

Bilateral inguinal hernias are relatively rare in females compared to men. The management outcome of bilateral nylon darn, a method predominantly used in sub-Saharan Africa for same time repairs in complicated or elective hernia surgeries is largely unknown.

Aims and Objectives:

Our aim is to report a rare case of same time bilateral inguinal hernia obstruction and review the outcome of bilateral nylon darn posterior wall repairs after herniotomy.

Design of the Study:

This was a retrospective analysis of bilaterally operated inguinal hernia female patients data that was retrieved for the past 6-year period. Settings: All complete records of female patients who had same time bilateral inguinal hernia repairs at the Margaret Marquart Catholic Hospital (district hospital), for the period January 2015 to December 2020 were included in the study.

Materials and Methods:

Patient biodata, clinical notes on diagnosis, surgical management, postoperative care, and complications were extracted from hospital records and analysed.

Results:

A total of 14 patients aged between 40 and 87 years which represented 1.85% of the total hernia repairs were female with same time bilateral inguinal hernia repairs. Seven (50%) patients presented at the emergency with hernias detected over a year. Surgical site infection and pains after surgery were the predominant complications and occurred more common after emergency repairs.

Conclusion:

Emergency bilateral inguinal hernia repairs were three times associated with surgical site infection compared to elective repairs.

Published: August 2022

Background:

Breast cancer is the most common malignancy affecting women in Nigeria. Presentation is usually elective. However, some patients present as an emergency with complications of the disease and its treatment. This study aimed to capture the features of this population of patients with breast cancer presenting as an emergency.

Materials and Methods:

The study was a prospective cross-sectional study conducted between March 2021 and February 2022. All the patients with histologically diagnosed breast cancer presenting as an emergency were recruited into the study. Relevant information was retrieved and analysed.

Results:

Over the study period, 34 patients were recruited. They were all females and ages ranged between 27 and 74 years of age (mean: 45.56 ± 11.71 years), and the highest incidence was in the fifth decade of life. The first symptom in all patients was a breast lump, and the duration of disease ranged between 3 and 84 months (mean: 29.21 ± 22.38 months). The right breast was most commonly involved, and invasive ductal carcinoma (no specific type) was the commonest histologic type in 88.24% of cases. Over half of the patients seen had received no treatment after establishing the diagnosis of breast cancer. For those who received treatment, radiotherapy was the least accessed form of treatment. The most common symptoms were difficulty breathing and jaundice (29.41% each), and metastatic disease was the most common diagnosis. The duration of admission ranged between 1 and 35 days, and a mortality rate of 45.45% was recorded.

Conclusion:

The most common indication for emergency presentation in patients with breast cancer was metastatic disease.
A retrospective observational study on pheno-endotypes of severe asthma among adults attending asthma clinic in a tertiary care centre in India
Authors: Talwar Deepak , Talwar Dhruv , Jain Nitin , Prajapat Deepak , Pahuja Sourabh
Published: August 2022

Background and Objective:

Severe asthma phenotyping based on invasive and non-invasive bio-markers assists in a better understanding of heterogeneity of clinical presentations and thereby using targeted therapies. Therefore, the current study was conducted to evaluate phenotypes based on non-invasive bio-markers of severe asthma patients attending a tertiary care hospital in North India.

Methods:

This was a retrospective, observational study conducted on the patients who visited the respiratory department of a tertiary care hospital in North India. Patients aged 18 years and above diagnosed with severe asthma were classified into distinct phenotypes, namely, atopic asthma, eosinophilic asthma, and Type 2 low asthma. Patients with their clinical and functional parameters were classified based on the levels of bio-chemical and hematological results [such as total/specific IgE, blood absolute eosinophil count (AEC)], skin prick tests, history of allergy, and the presence of allergic symptoms.

Results:

Out of total 100 severe asthmatics, the majority of the patients had an eosinophilic asthma (49%) phenotype, followed by atopic (allergic) asthma (36%) and Type 2 low asthma (15%) phenotypes. However, it was found that 29% of these patients had overlap of both atopy and eosinophilia. The atopic phenotype showed allergic symptoms, positive skin prick tests, and elevated IgE levels. The eosinophilic phenotype had high AEC (≥300 cells/uL) and low IgE (< 30 IU/ml) levels. The Type 2 low phenotype showed low AEC and IgE levels along with the absence of allergic symptoms. However, among these 100 patients, overlapping traits of both atopy and eosinophilia were labelled as overlap phenotypes. 50% of type 2 low severe asthma cases had eosinophils >150 cells/cmm and were eligible for mepolizumab.

Conclusions:

Identification of severe asthma pheno-endotypes based on simple non-invasive bio-markers is feasible in Indian settings, and it is of utmost importance for future treatment planning in these patients with available biologicals. Overlap of eosinophilic and atopic endotypes in one-third cases would challenge physicians to choose upfront appropriate biologicals in our country. Type 2 low asthma was least common with only <10% cases of severe asthma being ineligible for any biological.

Authors: Ofili Roy A. , Nwajei Anthony Ikechukwu , Aigbokhaode Adesuwa Queen , Owolabi Akinwumi Olayinka , Owolabi Mojisola Oluyemisi , Uzundu Emeka Christopher
Published: August 2022

Background:

Hypertension is a noncommunicable disease known to cause serious morbidity and mortality among adult population. In Nigeria, a developing nation currently experiencing harsh economic realities, the outcome of the disease can be influenced by the effect of various components of patient satisfaction on medication adherence.

Aim:

The aim of this study was to evaluate the influence of patient satisfaction on medication adherence and BP control among adult hypertensives attending the Medical OutPatient (MOP) Clinic of the Federal Medical Centre, Asaba, with a view to identifying those aspects of care that need improvement in health care settings thereby leading to improved patient satisfaction, better medication adherence and ultimately better BP control.

Patients, Materials and Methods:

This was a cross sectional study conducted among 200 adult hypertensive patients attending the MOP Clinic of the Federal Medical Centre, Asaba, from January 15th to April 15th, 2017. A semi-structured questionnaire consisting of four sections which are: sociodemographic characteristics, Modified 4-item Morisky Medication Adherence scale, patient satisfaction levels with services, and BP measurement were used for data collection.

Results:

A greater proportion 87 (43.5%) of the respondents rated overall satisfaction with care received as very good, while 23 (11.5%) rated it as being fair. A statistically significant relationship was noticed between overall levels of satisfaction with care and medication adherence, P < 0.001. The level of BP control among the respondents was also significantly associated with medication adherence, P < 0.001.

Conclusion:

Patient satisfaction was seen to have a significant association with medication adherence but not BP control. The custodians of health should endeavor to improve patient satisfaction among patients in the hospital as this study showed improved patient satisfaction to be associated with increased patient adherence to medication with attendant better BP control.

Published: August 2022

Aims:

The purpose of this study is to determine whether bisacodyl rectal suppository can reduce infective complications postprostate biopsy.

Patients, Materials and Methods:

This was a comparative cross-sectional study done at the urology unit of a tertiary hospital over 12 months. A sample size of 56 was determined using Fisher's formula. Both groups had tablets of ciprofloxacin 500 mg and metronidazole 400 mg at induction of anaesthesia and continued for three days postbiopsy at a dose of 500 mg twice daily and 400 mg thrice daily, respectively. In addition to antibiotics, those in Group 1 had 20 mg of bisacodyl (Dulcolax) suppositories given at night, starting two days before the procedure. The patients underwent digitally guided 10-core transrectal prostate biopsy on an outpatient basis. Blood and urine samples were taken for full blood count and urine culture, respectively, before surgery and three days after the biopsy. Statistical analysis was performed using the SPSS version 21.0. The level of significance was set at P < 0.05.

Results:

The mean age was 69.64 ± 9.31 with a range of 52–90 years. The peak age distribution was 70–79. In Group 1, two patients had urosepsis, one patient had urinary tract infection (UTI), and seven patients had bacteriuria, while in Group 2, four patients had urosepsis, four patients had UTI, and ten patients had bacteriuria.

Conclusions:

The addition of bisacodyl rectal suppository to antibiotics reduced the frequency of infective complications following prostate biopsy. The observed difference, however, was not statistically significant.

Background:

After several years of struggling due to many constraints, centers in Nigeria are now performing Gynecological Endoscopy (GE) procedures. This study describes the outcome of various GE procedures in patients with gynecological complaints in a tertiary hospital in South-West Nigeria.

Materials and Methods:

This study was a prospective longitudinal design. All eligible patients who had endoscopic procedures in the unit between May 2014 and April 2019 were recruited. Excluded were those who refused to take part in the study. The participants were followed up for a year. Data were collected during the preoperative, intraoperative, and postoperative periods. This data included the patient's sociodemographic characteristics, indications for the procedures, procedures carried out, and the procedures' outcome.

Results:

Of the 287 patients who had various procedures during this period, we recruited two hundred and seventy eligible patients (94.1%) for the study. We lost fourteen patients (5.2%) to follow up. One hundred and seventy-two (63.7%) had laparoscopy only. Eighty (29.6%) had hysteroscopy and laparoscopy, while the remaining 20 (6.7%) had hysteroscopy only. Thirty-eight (14.1%) were emergencies, while 125 (46.3%) were only diagnostic. Procedures carried out include hysteroscopic removal of missing intrauterine devices (6.3%) and laparoscopic tubal sterilization with Falope ring application (5.2%). We also carried out laparoscopic ovarian drilling for polycystic ovary syndrome (19.3%). Six patients (2.2%) had their surgery converted to laparotomy. We recorded no mortality.

Conclusion:

Our results showed the feasibility of GE surgery in Nigeria with an acceptable outcome. Local adaption and improvisation will ensure cost reduction and widespread use of these procedures in our setting.
Clinicopathological Factors Affecting Lymph Node Yield in Patients Undergoing Surgery in Head-and-Neck Squamous Cell Carcinoma in a Tertiary Care Center of North East India
Authors: Salvi Manisha , Bharadwaj Barasha S. , Deka Muktanjalee , Sharma Mridul , Goswami B. C.
Published: August 2022

Background:

Lymph node yield (LNY), number of lymph nodes recovered after neck dissection has been identified as a prognostic indicator for several cancers of non-head and neck sites as well as head-and-neck squamous cell carcinoma (HNSCC). Accurate estimation of LNY has been less evaluated in Indian settings. The purpose of this study was to estimate LNY in HNSCC patients, and to find out their association with clinicopathological factors.

Materials and Methods:

This was a single-center prospective study conducted on patients diagnosed with HNSCC who had undergone neck dissection with or without primary surgery. Grossing of all surgical specimens was done by guidelines under the College of American Pathologists (November 2021). LNY with their association with other clinic-pathological parameters were analyzed using SPSS software version 21.0.

Results:

A total of 2692 lymph nodes yielded from 112 samples of neck dissection with the mean LNY of 24.02 ± 9.69. A total of 192 lymph nodes were found to be positive with the mean lymph node ratio of 0.07 ± 2.96. Modified radical neck dissection versus selective node dissection performed cases, poor differentiation of tumor, higher tumor stage, more tumor thickness, and positive nodes for metastasis of squamous cell carcinoma were factors that contributed to higher mean LNY over 24.

Conclusions:

In an Indian setting, the mean LNY for HNSCC patients undergoing lymph node dissection is 24.02 and the factors such as node positivity, tumor differentiation, tumor stage, and higher tumor thickness affect the estimation of LNY.

Authors: Palsaniya Sudhir , Saini S. K. , Samar Aseem , Patni Sanjeev , Bapna Ajay
Published: August 2022

Background:

Gallbladder cancer (GBC) has a high incidence rate in the Indo-Gangetic belt and is usually presented in the unresectable advanced or metastatic stage. In this study, we evaluated the response rate and toxicities of the gemcitabine plus capecitabine (GEM-CAP)-based combination chemotherapy in unresectable or metastatic GBC patients.

Subjects and Methods:

This was an investigator-initiated, single-arm, prospective study conducted on unresectable or metastatic GBC patients at Jaipur, India, for 1 year. All the patients received a GEM-CAP combination chemotherapy regimen which consisted of gemcitabine 1000 mg/m2 intravenously over 30 min on days 1 and 8 and capecitabine at 800 mg/m2 orally twice a day for 14 days, administered every 21 days. The response was evaluated in terms of overall response rate (ORR), tumor control rate (TCR), and progression-free survival (PFS). Both quantitative and qualitative toxicities were assessed.

Results:

A total of 35 patients were enrolled, of which 3 patients were excluded due to treatment interruption. The mean age of patients was 55 (32–80) years, with the majority being female (77.14%), having an ECOG score of 1 (71.43%), and with Stage IVB disease (77.14%). The ORR was 25%, TCR was 50%, and median PFS was 4 months. Major toxicities noted were Grade I and II hematological and nonhematological toxicities, which were managed adequately.

Conclusion:

The combination therapy of gemcitabine and capecitabine is reasonable, feasible, and well-tolerated approach for the treatment of unresectable advanced and metastatic GBC patients, a disease that had limited treatment options.

Microbial communities, mainly those with probiotic characteristics, positively affect the culture of diverse organisms, including shrimp. In this study, three diets containing different types of probiotics were evaluated on the composition and diversity of the microbial community in the water column and gut of Litopenaeus vannamei, as well as on the expression of genes related to the immune system and resistance of the organisms after being challenged with WSSV and Vibrio parahaemolyticus. Results showed that probiotics affected the microbial community structure in water and shrimp. The expression of beta-glucan binding protein and prophenoloxidase increased in the treatments with probiotics compared to the control before and after the challenge. Overall the survival of shrimp was higher in all the treatments than in control. Results suggest that using probiotics in BFT systems could provide an extra benefit for these kinds of systems.
Upwelling Index Calculations in the Aegean Sea
Authors: Tükenmez Emre , ALTIOK Hüsne
Published: August 2022

Different upwelling index calculations used for oceans were tested by applying to the Aegean Sea and compared with each other. The sea surface temperature (SST) and wind data of ECMWF Reanalysis are used for upwelling index calculations. The decrease in SST is a result of upwelling; however, the parameter that lies behind the phenomenon is the wind stress on the sea surface. The results show that SST and wind-driven upwelling indexes could be roughly used to estimate upwelling phenomena in the Aegean Sea, but it is insufficient for the precise determination of upwelling due to the Aegean Sea`s unique dynamics. To reach a final formula, the `new upwelling index` shall be improved for Aegean Sea in which current data are considered besides SST & wind data.

Для данного уравнения получены решения с разделенными переменными, демонстрирующие разнообразное динамическое поведение. Большинство полученных решений не имеет аналогов в случае соответствующего локального нелинейного уравнения Шредингера. Эти результаты могут способствовать объяснению и развитию теории нелинейных волновых явлений, возникающих в нелокальных волновых режимах.

Изучается, как энтропия зацепленности излучения Хокинга, полученная с использованием островного подхода для черной дыры Рейснера-Нордстрeма, ведет себя по мере убывания массы черной дыры. Общий ответ на вопрос существенно зависит от характера убывания не только массы, но и заряда. Предполагается, что имеет место специальное соотношение между зарядом и массой $Q^2= GM^2[1-(M/\mu)^{2\nu}]$, которое называется уравнением связи. Обсуждается, существует ли такая связь, что энтропия зацепленности не возрастает в конце испарения, как это происходит в случае термодинамической энтропии и энтропии зацепленности для черной дыры Шварцшильда. Показано, что для некоторых специальных масштабных параметров энтропия зацепленности излучения не возрастает до тех пор, пока масса испаряющейся черной дыры превышает массу Планка.

Published: August 2022

Построены ($2\times2$)-матричные совместные решения скалярных линейных эволюционных уравнений $\Psi'_{s_k}=H^{3+2}_{s_k}(s_1,s_2,x_1,x_2, \partial/\partial x_1,\partial/\partial x_2)\Psi$ с временами $s_1$ и $s_2$, которые можно рассматривать в качестве аналогов временны́х уравнений Шредингера. Эти уравнения соответствуют так называемой гамильтоновой системе $H^{3+2}$, являющейся представителем иерархии вырождений изомонодромной системы Гарнье, описанной Кимурой в 1986 году. Данная совместная система гамильтоновых обыкновенных дифференциальных уравнений определяется двумя различными гамильтонианами $H^{3+2}_{s_k}(s_1,s_2,q_1,q_2,p_1,p_2)$, $k=1,2$, с двумя степенями свободы, соответствующими временны́м переменным $s_1$ и $s_2$. В терминах решений линейных систем обыкновенных дифференциальных уравнений методом изомнодромных деформаций, условием совместности которых являются гамильтоновы уравнения системы $H^{3+2}$, конструируемые совместные матричные решения аналогов временны́х уравнений Шредингера предъявлены явно. Приведена замена, связывающая матричные решения аналогов временны́х уравнений Шредингера, определяемых двумя формами (рациональной и полиномиальной по координатам) системы $H^{3+2}$. Эта замена представляет собой квантовый аналог известного канонического преобразования, связывающего гамильтоновы уравнения системы $H^{3+2}$ в двух данных формах.

Исследуются локализованные состояния в $s$-волновой сверхпроводящей полосе на поверхности топологического изолятора с перпендикулярным полем Зеемана. Аналитически доказано, что сколь угодно малое локальное возмущение поля Зеемана порождает андреевские локализованные состояния с энергиями вблизи границ сверхпроводящей щели, в то время как (немагнитный) примесный потенциал такого эффекта не вызывает. Достаточно большие возмущения поля Зеемана могут привести к появлению андреевских локализованных состояний с энергией вблизи нуля. Аналитически найдены волновые функции рассматриваемых андреевских локализованных состояний. В отличие от одномерного случая, волновые функции не удовлетворяют условиям сопряжения, характерным для майорановских состояний, вследствие влияния ближайших подзон.

Published: August 2022

As a sustainable and eco-friendly alternative to fresh or new materials for road construction and
maintenance, recycled or reclaimed asphalt pavement (RAP) is being used more frequently. There
are no specific criteria, norms, or methods for identifying recovered asphalt materials in India or other
developing nations. Classifying the RAP materials that are now accessible for use in road construction
is therefore urgently necessary. Costs associated with highway projects can be cut by 25–30% by
reusing these materials. There have been some reported studies in India where new materials were
swapped out for RAP in the binder course, but there are undoubtedly many more that have not yet
been documented. The goal of the current experiment is to determine the aggregate mix percentage
for DBM layers with various percentages of RAP. The RAP sample was taken from the NH209
Kanakpura Road.

Authors: Vardevanyan Poghos H. , Petrosyan Nara R.
Published: August 2022

Structural transitions of DNA and bovine serum albumin (BSA) and their complexes with methylene blue (MB) and Hoechst 33258 (H33258) by UV-denaturation method have been studied. The obtained results revel that MB stabilizes both protein dimensional structure and DNA double-stranded structure, while H33258 stabilizes double-stranded structure of DNA and destabilizes protein structure. It was also revealed that the stabilizing effect of MB on native structure of DNA is more pronounced at relatively low ligand concentrations, than on protein.

Published: August 2022

Micro, Small and Medium Enterprises (MSMEs) contribute to the Gross National Income (GDP) up to 40% and the creation of new job vacancies. Based on 25% of the total number of MSMEs in Indonesia cannot produce during the pandemic. In addition, internal problems such as lack of business knowledge, IT updates, low understanding in market make most MSMEs have low firm performance. Firm performance is an important part of a company to observe and evaluate the suitability of the results in business activities with the predetermined plan. Some researchers believe that firm performance is affected by Entrepreneurial Orientation and Market Orientation. This research was conducted by MSMEs that  run their businesses in Malang City, East Java Indonesia. Data collection uses non-probability method approach with simple random sampling technique. The number of respondents collected in this study amounted to 112 respondents, but which can be used in data processing was amounted to 101 respondents. The method of data analysis uses SEM (Structural Equation Modeling) based on Partial Least Square (PLS) using SmartPLS 3.3 software application. This study aims to investigate the role of Entrepreneurial Orientation and Market Orientation in improving the performance of MSMEs. The research findings that entrepreneur orientation and market orientation are proven to have an effect on improving the performance of MSMEs. However, entrepreneur orientation cannot have a direct impact on improving performance. Entrepreneur orientation must be supported by market orientation in improving MSME performance
PARA DENTRO DAS PESSOAS, AS PESSOAS CAÍAM

Published: August 2022

O artigo analisa os diferentes modos como a solidão é retratada na obra O filho de mil homens, de Valter Hugo Mãe, em torno das personagens Crisóstomo e Antonino. Embasando-se epistemologicamente nas discussões a respeito de solidão e solitude de Maria Homem (2018), Martin Heidegger (2015) e Emmanuel Lévinas (1982); de gênero, sexo e sexualidade feitas por Judith Butler (2015); de estigma feitas por Goffmann (1975) e Cardoso & Siqueira (2011); das análises da personagem Antonino feitas por Teotônio (2019); bem como a partir da análise do texto literário, procura-se refletir quanto: 1) à importância da posição do narrador, no que diz respeito à estratégia narrativa, para a construção das personagens e das diferentes solidões; e 2) às maneiras pelas quais o narrador constrói as personagens de modo a retratar as estruturas sob as quais a sociedade da diegese está alicerçada. À luz dos pressupostos teórico-metodológicos da Literatura Comparada, os procedimentos adotados caracterizam esta pesquisa como qualitativa, bibliográfica e de caráter exploratório. O estudo evidenciou os distintos modos como a solidão é representada: no caso de Crisóstomo, a partir do próprio indivíduo, em virtude da falta do Outro; em oposição, a solidão que atinge Antonino tem uma origem social, em decorrência de processos de produção da diferença e de estigmatização. Ademais, constatou-se a relevância da estratégia narrativa na construção dos sujeitos e das solidões que os atravessam, podendo-se inferir as estruturas discursivas às quais os indivíduos da sociedade retratada estão submetidos.
CASA DA FICÇÃO E SUAS MÚLTIPLAS JANELAS
Authors: Rodrigues Cléverson Felix , Felix José Carlos
Published: August 2022

Este artigo propõe uma reflexão de como as diferentes perspectivas do projeto literário do escritor Henry James, produzidas por sua fortuna crítica, resultou, ao longo do século XX, nas mais diversas chaves interpretativas, como formalista, mimética, entre outras. Partimos de um tensionamento constitutivo da fortuna crítica produzida por teóricos como Austin-Smith (1992), Blackmur (1984), Booth (1983), Lubbock (1976), Wellek (1958) e Bellei (1998) para examinarmos a tendência estabelecida em produzir uma crítica pautada tanto em seus ensaios e prefácios sobre a natureza do romance, a exemplo de seu livro A Arte da ficção (1884; 1995), quanto de sua prolífica prosa ficcional. Para além de uma mera revisão e apresentação sistemática da fortuna crítica de Henry James, tal reflexão tem por objetivo estabelecer o mote para, na segunda seção do texto, discutirmos como os procedimentos de elisão entre o narrador onisciente com personagens refletores (Beach, 1932), no romance As Asas da Pomba (The Wings of the Dove, 1902), juntamente com telling and showing (Booth, 1983), narrador onisciente (Friedman, 2002) e ambientação reflexa (Lins, 1976) constituem um conjunto de experimentos estéticos que conferem a Henry James a alcunha de um escritor avant lalettre no modernismo em língua inglesa.

La sepsis es la respuesta desregulada del organismo ante una infección, es una enfermedad compleja y controvertida en cuanto a su clasificación, epidemiología, presentación, diagnóstico y tratamiento. Varios estudios epidemiológicos recientes demuestran que su incidencia aumenta y genera un importante consumo de recursos. La sepsis es una causa frecuente de ingreso en las unidades de terapia intensiva pediátrica que se estima que hasta el 8 % de los ingresos pueden ser debidos a esta causa y que tiene una mortalidad de hasta el 25%.

El hemocultivo es el método diagnóstico que se realiza para la detección, identificación y susceptibilidad antimicrobiana de microorganismos en la sangre. El momento de la toma de muestra lo dicta la gravedad del paciente. En situaciones urgentes, como la sepsis, deben ser obtenidos dos o más sets en un intervalo corto de minutos antes del inicio de la terapia empírica inicial. En situaciones menos urgentes, como la endocarditis, deben tomarse al menos una serie de dos sets en 24 horas. En caso de sospecha de bacteriemia relacionada con catéter se deben obtener muestras de sangre de todos los lúmenes del catéter venoso central y de una vena periférica.

La detección de la bacteriemia y la fungemia constituye una de las prioridades en el ejercicio médico y microbiológico ya que se asocia con una elevada mortalidad, es por esto su importancia diagnóstica en el manejo de los pacientes. A lo largo de los años se han producido importantes cambios en la incidencia y en la etiología de la bacteriemia y la fungemia, así como en los métodos para detectarlas; por eso se ha considerado imprescindible revisar y poner al día los procedimientos óptimos para que el principal medio para detectarlos, como es el hemocultivo, se lleven a cabo en condiciones óptimas y por tanto contar con la disposición de protocolos de trabajo normatizados.

El procesamiento de los hemocultivos, una vez llegada la muestra al laboratorio de microbiología, dependerá de las facilidades tecnológicas con las que cuente la institución, y del tipo de microorganismo que se sospeche desde el punto de vista clínico, lo cual debe ser notificado al laboratorio por el equipo tratante. El Microbiólogo con base a estas premisas decidirá temperaturas de incubación, frecuencia y momento de subcultivos y de pruebas de identificación y antibiograma que permitan la más eficaz y oportuna toma de decisiones terapéuticas.
