Descripción de los pacientes de 80 o más años intervenidos quirúrgicamente en el laboratorio de electrofisiología en un hospital de tercer nivel
Authors: Acosta Sánchez Daniela , Bautista Vargas William Fernando
Published: March 2021

Introducción: en una unidad de electrofisiología de un hospital de tercer nivel de Manizales, Caldas, se han atendido pacientes en la cuarta edad; sin embargo, existe poca claridad en la literatura sobre las conductas terapéuticas en este grupo etario. Presentamos nuestra experiencia de atención e intervención en pacientes mayores de 80 años entre el 20 de septiembre de 2017 y 7 de octubre de 2019.

Métodos: estudio tipo cohorte longitudinal, se recogió información con base en revisión de historias clínicas. Se realizaron seguimientos telefónicos al tercer y sexto mes del procedimiento. Se incluyeron pacientes mayores de 80 años intervenidos de cualquier procedimiento en la sala de electrofisiología. Se excluyeron los pacientes sin información sobre los datos de seguimiento.

Resultados: se recogieron datos de 75 pacientes llevados a procedimiento. El 62.7% de los pacientes fueron hombres, las edades oscilaron entre 80 y 95 años. 32.7%, de pacientes con diagnóstico de disfunción sinusal. La comorbilidad más prevalente fue hipertensión arterial (92%). El procedimiento más realizado fue el implante de marcapaso bicameral. La mediana del tiempo de estancia hospitalaria fue de 1 día. EL 70% de los pacientes tuvieron riesgo medio o bajo según la escala CHA2DS2VASc. En el lapso de seis meses se encontró una incidencia acumulada de complicaciones de 4%, con 8% de reconsultas y una mortalidad de 1.3%.

Conclusiones: las complicaciones posquirúrgicas, la necesidad y duración de la hospitalización, la tasa de reconsulta y la mortalidad asociada a los procedimientos en este grupo de edad son similares a las observadas en estudios con población menor de 80 años.

CONTEXT:
rd The term “menopause” means permanent cessation of menstruation. Women spend 1/3 of life in this phase. Decrease in the
production of estrogen leads to symptoms like hot ushes, insomnia, mood changes, as well as osteoporosis and vaginal atrophy. These changes
lead to decrease in quality of life and make them more vulnerable to physical health problems and mental health disorders. Early identication and
treatment of symptoms will improve their quality of life.
OBJECTIVES: 1) To study the Sociodemographic factors among postmenopausal women. 2) To determine the prevalence of menopausal
symptoms among the study subjects.
MATERIALS & METHODS: Across-sectional community based study was conducted in urban eld practice area of tertiary health care centre
among 200 Postmenopausal women with natural menopause. Women with surgical/medical menopause & on medications like antidepressants,
anxiolytics were excluded. Data was collected using semi structured questionnaire and analysed using MS Excel 2007
RESULTS: Mean age at menopause is 46.11 + 4.28 years. Most frequent symptom reported by study subjects was joint pains (52%). Most
common vasomotor symptom reported was hot ushes (38.5%), most common psychological symptom was sleep disturbances (42%) and most
common urogenital symptom was increased urine frequency (23%). Least common symptoms reported were vaginal dryness (3%)
CONCLUSIONS: Majority of postmenopausal women (172 out of 200)are suffering from one or the other menopausal symptom.

Authors: R Naik Viraj , Jindal Manjusha , Naik Siddhi D.
Published: March 2021

Introduction: (1) The female genital tract is constituted by the ovaries, fallopian tubes, uterus (body/corpus and cervix), vagina, and vulva. Female genital tract lesions can be benign or malignant. Our study was carried out to nd out the frequency of various histopathological lesions including neoplasms of female genital tract. Materials and Methods: Our study is retrospective conducted over 2 years period. Data was collected from case records of patients presenting to Goa Medical College and histopathology reports obtained from Dept of pathology. Data was represented in form of charts and tables. The analysis of statistical data of variables was done using SPSS software version 22. Signicance was calculated using chi square test. Value of p <0.05 was considered signicant. Results: Out of total 270 subjects studied, 229 were having benign lesions and 41 had malignant lesions.The mean age was 49.5 years. Leiomyoma was diagnosed in (40.58%) cases. In abnormalities of endometrium proliferative endometrium was seen in 37.6%. Chronic cervicitis was seen 78.74% cases. Among the ovarian lesions, 67.74% cases were simple follicular cysts. Cervical cancer was found in 73.17% cases followed by ovarian malignancies in 19.51 % cases, endometrial carcinoma in 4.87% cases and vulvar cancer in 2.44% cases. Among the malignant tumors (58.54%) cases were postmenopausal women. Conclusion: Microscopic assessment and clinico-pathological correlation of lesions is necessary as grossly identiable benign lesion may harbour a focus of malignancy. It aids to appropriate management in the postoperative period. A concerted effort should be done towards prevention of cancers, by creating awareness through health education in addition to implementation of screening methods.
Multimodal Sensor Selection for Multiple Spatial Field Reconstruction
Authors: Nguyen Linh , Thiyagarajan Karthick , Ulapane Nalika , kodagoda sarath
Published: March 2021

The paper addresses the multimodal sensor selection problem where selected collocated sensor nodes are employed to effectively monitor and efﬁciently predict multiple spatial random ﬁelds. It is ﬁrst proposed to exploit multivariate Gaussian processes (MGP) to model multiple spatial phenomena jointly. By the use of the Matern cross-covariance function, cross covariance matrices in the MGP model are sufﬁciently positive semi-deﬁnite, concomitantly providing efﬁcient prediction of all multivariate processes at unmeasured locations. The multimodal sensor selection problem is then formulated and solved by an approximate algorithm with an aim to select the most informative sensor nodes so that prediction uncertainties at all the ﬁelds are minimized. The proposed approach was validated in the real-life experiments with promising results.
Woman Stereotypes and Patriarchal Hegemony: A Feminist Stylistics Analysis of Iraqi Folk Proverbs
Authors: A. G. Al-Zubaidi Asst.Prof.Dr. Nassier
Published: March 2021

The present research examines the stereotypical representations of women and women's position in the discourse practices of Iraqi folk proverbs from a feminist stylistics perspective. Sara Mills' (2008) theoretical framework is adopted to analyze a sample of 315 proverbs drawn from written and oral sources. The analysis reveals that the sub-categories of woman in general and wife in particular are the most frequently targeted in Iraqi proverbs. Personal attributes are the most salient properties associated with Iraqi women compared to physical attributes. Women are generally represented negatively in the Iraqi proverbial discourse where proverbs are generally manipulated to disparage and denigrate women. The traditional ideals of hegemonic masculinity, patriarchal ideology and gender inequality are encoded in the discourse of these proverbs. That is, the institutionalization of male domination and the secondary position of women are grounded in the structure of Iraqi society. Finally, a number of conclusions are presented

This research is devoted to study the performance of Iraqi  EFL learners with reference to  idiomatic expressions in modern Standard English.By  definition , an idiom  is  a  linguistic unit  in  which the meaning of a  given construction cannot  be  understood  from  the  words that  compose  it. Evidence  shows that  English  idiomatic  expressions represent  a  rather  problematic  area  for  EFL  learners . Thus , this  study aims  at theoretically  investigating  the  English  idiomatic  expressions   and  practically  studying  the  Iraqi  EFL  learners'  performance in  dealing  with these  expressions by  means  of  a  specialized  test  designed  for  this  purpose . It  is  hypothesized  that  Iraqi  EFL learners  face  difficulties  in  dealing  with idiomatic expressions in  both  recognition  and  production  levels . The  test  includes  two  questions , each  with  25  items. Results  show  that , at  the  recognition  level ( question 1) , most  Iraqi  EFL  learners  fail  in  recognizing the  idiomatic  expressions , whereas  at  the  recognition  level the  percentage  of  learners  unable  to  employ the  given  idiomatic expressions  increased  including  the  avoided  items , which  are  considered  as  incorrect  in  both  first  and  second  questions . The findings  arrived  at  support  the  above  mentioned  hypothesis . The study ends with some of the  recommendations  for  EFL teachers and learners and the way they encounter   such  expressions  in  spoken  and written English

The present paper tackles the viewpoints of Russian literary critics, and their evaluation of contemporary writers, along with their roles in the development of the Twenty-First century literature. We have pointed out the importance of the works of   Viktor Pelevin, Valdimir Makanin, and Vladimir Sorokin, and how they influenced modern Russian literature. Also, it has been showed that these writers were not less important than the Russian classic writers, despite that some of their works were characterized with a sense of dialectic with the classic text. Thus, a contemporary Russian text has  become desired and understood all over the world.
القمر في الثقافة العراقية القديمة: اعادة قراءة لرواية" الهلال" لديانا ابو جابر و"طشاري" لأنعام كججي
Authors: Hashim Taher Asst. Prof. Isra
Published: March 2021

Man used to attribute good and evil in his life to celestial bodies. Therefore, ancient civilizations paid much attention to astronomy which had a lasting impact on mythology and religion. In ancient Iraqi mythology, sad and happy events like war and peace, death and fertility, flood and famine, were attributed to the appearance and disappearance of the moon.Among the post-modern writers who wrote novels about Iraq are the Arab-American Diana Abu Jaber (1959 -) and the Paris-based Iraqi Inaam Kachachi (1952 -). Abu Jaber's Crescent (2003) tells a love story between an Iraqi professor and an Iraqi-American girl. The crescent of the title has to do with the Islamic ritual of marking the beginning of a lunar month like Ramadhan. As the novel suggests it has to do with patience and the unknown as represented  by the sudden and unexpected reappearance of the protagonist (Hanif) after a long time of absence. Whereas Kachachi's Tashari (2013) details the scattering of Iraqis in different parts of the world after the-2003 events. It attributes this tragedy to the Pope's  refusal to visit the city of  Ur, the birthplace of Prophet Abraham which also used to be the residence of Nana, the moon god of the ancient Sumerians. While apparently both novels deal in part with the religious beliefs and practices related to the moon in Islam and Christianity, they, however, make no direct reference to ancient Iraqi myths. Although Abu Jaber expressed the wish of writing about "the legacy of Iraq", "the cradle of civilization"  and Kachachi wrote mainly about Iraq and its " good old days", but rarely they made a direct reference to the moon and its significance in ancient Iraqi culture. Nevertheless, both novels implicitly abound in references to the moon that can be analyzed in terms of its status and the lasting impact it had on ancient Iraqi culture, which will be the focus of this paper.

Composites are materials which are mixed with one or more different and heterogeneous reinforcement. Matrix materials can generally be polymers, ceramics and metals. The matrix in the composite serves to distribute the load into all reinforcing material. Matrix properties are usually ductile. The reinforcing material in the composite has the role of holding the load received by the composite material. The nature of the reinforcing material is usually rigid and tough. Strengthening materials commonly used so far are carbon fiber, glass fiber, ceramics. The use of natural fibers as a type of fiber that has advantages began to be applied as a reinforcing material in polymer composites. This study seeks to see the effect of the use of bamboo natural fibers in polyester resin matrix on the strength of polymer composites with random and straight lengthwise fiber variations. From the tensile test results it can be seen that bamboo fibers can increase the strength of polymer composites made from polyester resin and the position of the longitudinal fibers gives a significantly more strength increase than random fibers.

Published: March 2021

This study investigated the relationship between bedtime Compulsive Social Media Use (CSMU) on students' sleep quality in the Copperbelt Colleges of Education, Zambia. Mixed method was utilised to solicit data from a sample of five hundred and seventy-nine (579) college students who were drawn from three (3) public and three (3) private colleges. Bergen Social Media Addiction Scale (BSMAS) and Pittsburgh Sleep Quality Index (PSQI) scale were utilised for data collection. Quantitative data were analysed using Statistical Package for the Social Science, whereas qualitative data was analysed using thematic analysis. Findings showed provision of pleasure as motive that compiled students to use social media during bedtime. Besides, it was established that students were spending less than 8 hours of sleep. However, the negative correlation between CSMU and sleep quality was evident. Therefore, the study recommends that college managements should conduct awareness programs to educate students on the negative effects of excessive usage of social media, particularly during bedtime.

Rice is a staple food in the world market, especially in the Asian region. In each country, the characteristics of rice will be different in terms of shape, grade and size. The quality of rice depends largely that demonstrate the quality of that rice species. At present, information on rice varieties is still limited regarding the physical properties of Malaysian and Thai rice. Therefore, it is important to compare rice cultivars based on origin. The objective of this research is to determine and compare the physical properties of Malaysian and Thai rice. 1 kilogram of Malaysian and Thai rice were each processed into powder by way of grinding and were then prepared for physicochemical measurement by sieving the produced rice powders with a size of 2mm to get rid of foreign objects. The physical parameters measured were length, width, length/breadth ratio, thickness, density, grain shape, surface area, bulk density, true density, porosity, sphericity, aspect ratio, thousand weight kernels angle of repose, colour (L, a*, b*) and hardness. The results of the study showed no significant differences (p>0.05) in terms of length, width, length/breadth ratio, true density, porosity, sphericity, aspect ratio, angle of repose, Lightness (L) and b*. However, there is a significant variation (p < 0.05) between Malaysian and Thai rice in terms of thickness, surface area, bulk density, thousand weight kernels, colour (a*) and hardness parameters. The evaluation of the quality of Malaysian and Thai rices can be a guide or reference for the grading and sorting processing sectors.

Мета. Вивчення споживних характеристик конопляних тканин, які використовуються для виготовлення верху взуття.
Методика. Теоретичні та експериментальні дослідження в роботі, вирішувалися за допомогою сучасних методів та методик, аналізу, вимірювання з використанням діючої нормативної документації. Визначення волокнистого вмісту експериментальних зразків проводили за допомогою методики світлової мікроскопії.
Результати. Інтерес у використанні технічних конопель в легкій промисловості з кожним роком зростає не тільки закордоном, але й в Україні. Багато вітчизняних підприємців з виробництва текстильних виробах використовують натуральні, екологічно чисті конопляні волокна. Це зумовлено, перш за все, високими якісними властивостями волокон даної культури. Коноплеволокно має більшу зносостійкість та міцність, навіть в порівнянні з лляними або бавовняними волокнами. Ці волокна володіють високими гігроскопічними властивостями. Завдяки пористій структурі конопляного волокна тканина нього здатна увібрати вологу до п’ятисот відсотків від своєї ваги. Також, ці волокна гіпоалергенні. Але наряду з такими якісними показниками коноплеволокно має високий показник відносного розривного подовження, що негативно впливає на експлуатаційні характеристики взуттєвих товарів. В даній роботі було проаналізовано всі фактори негативного впливу тканин на основі волокон технічних конопель на формостійкість взуттєвих виробів:- високий показник відносного розривного подовження конопляного котоніну – 17,2%;- волокнистий та відсотковий склад ниток за основою і утоком в тканинах верху взуття;- вид переплетення тканини верху взуття. На основі проведених експериментальних досліджень запропоновано низку наукових гіпотез, які дають змогу вирішення негативного впливу вищенаведених факторів на експлуатаційні властивості взуття з технічних конопель. Реалізація даних гіпотез підвищить якість вітчизняних виробів з технічних конопель та зробить їх конкурентоспроможними на вітчизняному та європейських ринках.
Наукова новизна. Вперше запропоновано наукові гіпотези з усунення негативних факторів, які впливають на експлуатаційні властивості конопляних тканин призначених для верху взуття.
NEUTRINOLESS DOUBLE BETA DECAY EXPERIMENTS

Published: March 2021

Neutrinoless double beta decay is a lepton number violating process which is not allowed in the Standard Model (SM) of the electroweak interaction. The discovery of this process will be an unambiguous confirmation of the existence of New Physics outside the SM. At this moment many experiments are being conducted aimed at searching for neutrinoless double beta decay on various isotopes (76Ge, 136Xe, 130Te, 100Mo, etc.). The paper presents a brief overview of the results of some current projects, such as GERDA, MAJORANA, KamLAND-Zen, EXO-200, CUORE and SuperNEMO, and plans for creating a new generation experiments.

Published: March 2021

The stability of the separation efficiency of the MASHA setup was studied under high current conditions and long-term experiments. The system of solid-state separation of volatile products of fusion reactions was optimized, a new design of a “solid-state hot catcher” based on thin layers of graphene and carbon nanotubes was designed and tested. The experiments showed the possibility of using these materials at a heavy ion beam intensity ∼ 0.5 part ·𝜇A. For constant monitoring of the installation separation efficiency during the experiment, 16-strip silicon detector was placed in the intermediate focal plane. The control system was debugged in an experiment for simultaneously measure two complete fusion reactions: 40 Ar + 144Er in the intermediate focal plane and 40Ar + 166Er in the main focal plane of the mass spectrometer.
The presumed influence of election misinformation on others reduces our own satisfaction with democracy
Authors: Nisbet Erik C. , Mortenson Chloe , Li Qin
Published: March 2021

Pervasive political misinformation threatens the integrity of American electoral democracy but not in the manner most commonly examined. We argue the presumed influence of misinformation (PIM) may be just as pernicious, and widespread, as any direct influence that political misinformation may have on voters. Our online survey of 2,474 respondents in the United States shows that greater attention to political news heightens PIM on others as opposed to oneself, especially among Demo-crats and Independents. In turn, PIM on others reduces satisfaction with American electoral democ-racy, eroding the “virtuous circle” between news and democracy, and possibly commitment to de-mocracy in the long-term.
Shannon Capacity and the Categorical Product
Authors: Simonyi Gábor
Published: March 2021

Shannon OR-capacity $C_{\rm OR}(G)$ of a graph $G$, that is the traditionally more often used Shannon AND-capacity of the complementary graph, is a homomorphism monotone graph parameter therefore $C_{\rm OR}(F\times G)\leqslant\min\{C_{\rm OR}(F),C_{\rm OR}(G)\}$ holds for every pair of graphs, where $F\times G$ is the categorical product of graphs $F$ and $G$. Here we initiate the study of the question when could we expect equality in this inequality. Using a strong recent result of Zuiddam, we show that if this "Hedetniemi-type" equality is not satisfied for some pair of graphs then the analogous equality is also not satisfied for this graph pair by some other graph invariant that has a much "nicer" behavior concerning some different graph operations. In particular, unlike Shannon OR-capacity or the chromatic number, this other invariant is both multiplicative under the OR-product and additive under the join operation, while it is also nondecreasing along graph homomorphisms. We also present a natural lower bound on $C_{\rm OR}(F\times G)$ and elaborate on the question of how to find graph pairs for which it is known to be strictly less than the upper bound $\min\{C_{\rm OR}(F),C_{\rm OR}(G)\}$. We present such graph pairs using the properties of Paley graphs.

Authors: Ene Viviana , Herzog Jürgen , Qureshi Ayesha Asloob , Romeo Francesco
Published: March 2021

We study the coordinate ring of an $L$-convex polyomino, determine its regularity in terms of the maximal number of rooks that can be placed in the polyomino. We also characterize the Gorenstein $L$-convex polyominoes and those which are Gorenstein on the punctured spectrum, and compute the Cohen–Macaulay type of any $L$-convex polyomino in terms of the maximal rectangles covering it. Though the main results are of algebraic nature, all proofs are combinatorial.
SEDIMENT GRAIN-SIZE COMPOSITION IN LAKE ANASHKINO (SOUTH-WESTERN ONEGO AREA)
Authors: Myasnikova N. A.
Published: March 2021

The lithostratigraphy and grain-size composition of sediments in Lake Anashkino (south-western Onego area) are described. The younger, upper sediment layers showed a prevalence of very fine sand. Further down the sediment, there dominate coarse and medium silt fractions, and down from the depth of 10.03–10.16 m — medium and fine silt. The oldest sediments (at 10.19–10.20 m) feature a prevalence of very coarse and coarse silt, and further below (10.30–10.31 m) there prevail very fine sand and very coarse silt fractions. The prevalent activity in the palaeo-hydrodynamic environments in which the ancient sediments (9.96–10.31 m) were deposited was turbidite flows. Younger sediments (9.32–9.92 m) were deposited in the environment of low-velocity flows. The sediment formation pattern in Lake Anashkino during the change from a nival to a humid climate suggests there happened five shifts in dynamic water regimes.

Forest Fires and Losses Caused by Fires – An Economic Approach
Authors: Sadowska Beata , Grzegorz Zimon , Stępnicka Nina
Published: March 2021

A defined forested area performs various functions such as economic, protective and social. Regardless of the level of civilization development and human knowledge, it cannot be stated that humans have full control over the phenomena occurring in forests or their surroundings. Forest hazards, including fire hazards, constitute a direct or indirect factor of human activity that has an effect on nature. Forest fires cause specific losses and generate costs, thus affecting a financial result. The research area of the study is forest fires and losses caused by them, i.e. determining the financial and non-financial effects of fires. The main aim of the study is to present the problem of forest fires in selected European countries, including Poland, and to determine the level of losses caused by them. The research hypothesis is: "Forest fires occurring in European countries, including Poland, cause significant losses in the natural and social environment, which forces organizations to incur costs of implementing measures to protect forest areas against fires". In the case of Poland, the area of interest is public forests managed by the State Forests National Forest Holding. The following research methods were used: critical analysis of the literature, comparative method, desk research, the method of induction and synthesis. In the field of empirical research, the current research results and studies of the Central Statistical Office and the reports of the State Forests were used.

Background: In cases of locally advanced breast cancer (labc), preoperative (“neoadjuvant”) therapy was traditionally reserved to render the patient operable. More recently, neoadjuvant therapy, particularly chemotherapy, is being used in patients with operable disease to increase the opportunity for breast conservation. Despite the increasing use of preoperative chemotherapy, rates of pathologic complete response, a surrogate marker for disease-free survival, remain modest in patients with locally advanced disease and particularly so when the tumour is estrogen or progesterone receptor–positive and her2-negative. A new paradigm for labc patients is needed. In other solid tumours (for example, rectal, esophageal, and lung cancers), concurrent chemoradiotherapy (ccrt) is routinely used in neoadjuvant and adjuvant treatment protocols alike. Results: The literature suggests that ccrt in labc patients with inoperable disease is associated with response rates higher than would be anticipated with systemic therapy alone. Conclusions: Ongoing trials in this field are eagerly awaited to determine if ccrt should become the new paradigm.
Safe Handling of Cytotoxics: Guideline Recommendations
Authors: Easty A.C. , Coakley N. , Cheng R. , Cividino M. , Savage P. , Tozer R. , White R.E.
Published: March 2021

Background: This evidence-based practice guideline was developed to update and address new issues in the handling of cytotoxics, including the use of oral cytotoxics; the selection and use of personal protective equipment; and treatment in diverse settings, including the home setting. Methods: The guideline was developed primarily from an adaptation and endorsement of an existing guideline and from three systematic reviews. Before publication, the guideline underwent a series of peer and external reviews to gather feedback. All comments were addressed, and the guideline was amended when required. The guideline applies to health care workers who could come into contact with cytotoxic drugs at any point in the medication circuit. The intended users are hospital administrators, educators, and managers; occupational health and safety services; and pharmacy and health care workers. Results: The recommendations represent a reasonable and practical set of procedures that the intended users of this guideline should implement to minimize opportunities for accidental exposure. They are not limited to just the point of care; they cover the entire chain of cytotoxics handling from the time such agents enter the institution until they leave in the patient or as waste. Conclusions: Reducing the likelihood of accidental exposure to cytotoxic agents within the medication circuit is the main objective of this evidenced-based guideline. The recommendations differ slightly from earlier guidelines because of the availability of new evidence.
Perspectives on Treatment Advances for Stage III Locally Advanced Unresectable Non-Small-Cell Lung Cancer

For more than a decade, there has been no improvement in outcomes for patients with unresectable locally advanced (LA) non-small-cell lung cancer (NSCLC). The standard treatment in that setting is definitive concurrent chemotherapy and radiation (CCRT). Although the intent of treatment is curative, most patients rapidly progress, and their prognosis is poor, with a 5-year overall survival (OS) rate in the 15%–25% range. Those patients therefore represent a critical unmet need, warranting expedited approval of, and access to, new treatments that can improve outcomes. The PACIFIC trial, which evaluated durvalumab consolidation therapy after CCRT in unresectable LA NSCLC, demonstrated a statistically significant and clinically meaningful improvement in progression-free survival (PFS) and a significant improvement in OS. Durvalumab thus fills a critical unmet need in the setting of unresectable LA NSCLC and provides a new option for patients treated with curative intent. Here, we review the treatment of unresectable LA NSCLC, with a focus on the effect of the clinical data for durvalumab.

Published: March 2021

Background: Venous thromboembolism (VTE) in malignancy is associated with poor outcomes. We conducted a retrospective review of VTE in patients with endometrial cancer to characterize the VTE incidence, identify factors that contribute to VTE risk, and compare survival outcomes in patients with and without VTE. Methods: A retrospective chart review identified 422 eligible patients who underwent surgery for endometrial cancer (1 January 2014 to 31 July 2016). The primary outcome was VTE. Binary logistic regression identified risk factors for VTE; significant risk factors were included in a multivariate analysis. Kaplan–Meier estimates are reported, and log rank tests were used to compare the Kaplan–Meier curves. Risk-adjusted estimates for overall survival based on VTE were determined using a multivariate Cox proportional hazards model. Results: The incidence of VTE was 6.16% overall and 0.7% within 60 days postoperatively. Non-endometrioid histology, stages 3 and 4 disease, laparotomy, and age (p < 0.1) were identified as factors associated with VTE and were included in a multivariate analysis. The overall death rate in patients with VTE was 42% (9% without VTE): hazard ratio, 5.63; 95% confidence interval, 2.86 to 11.08; p < 0.0001. Adjusting for age, stage of disease, and histology, risk of death remained significant for patients with a VTE: hazard ratio, 2.20; 95% confidence interval, 1.09 to 4.42; p = 0.0271. Conclusions: A method to identify patients with endometrial cancer who are at high risk for VTE is important, given the implications of VTE for patient outcomes and the frequency of endometrial cancer diagnoses. Factors identified in our study might assist in the recognition of such patients.

Published: March 2021

Background: Almost half of all patients with non-small-cell lung cancer (nsclc) present with stage iv disease. The objective of the present study was to characterize treatment patterns and survival outcomes in patients with advanced nsclc. Methods: We conducted a longitudinal population-level study in patients diagnosed with stage iv nsclc in Ontario between 1 April 2010 and 31 March 2015, with follow-up to 31 March 2017 for overall survival and treatment sequence. Patients were stratified as nonsquamous or squamous histology. A sub-analysis was conducted for patients with nonsquamous histology who received targeted therapies, on the assumption that their tumours were EGFR mutation–positive (EGFRm+). Treatment patterns were determined, and survival was calculated from date of diagnosis to death or censoring. Results: Of 24,729 nsclc cases identified, stage iv disease was diagnosed in 49.2%, histology was nonsquamous in 10,103, and EGFRm+ was assumed in 508. Median patient age ranged from 69 to 72 years for the three cohorts. For patients with nonsquamous histology, palliative radiotherapy was the most frequently used first-line treatment (44.4%), followed by no treatment (26.7%) and chemotherapy (14.9%). In the EGFRm+ cohort, 75.6% received gefitinib as first- or second-line therapy, and almost half (47.4%) the 473 patients with squamous histology treated with first-line chemotherapy received cisplatin or carboplatin with gemcitabine. Median overall survival in the nonsquamous and squamous cohorts was 4.9 and 4.6 months respectively; it was 17.6 months for patients who were EGFRm+. Conclusions: Survival of patients with stage iv nsclc remains poor, with the exception of patients who are EGFRm+. Only 14.9% of patients received first-line chemotherapy; the mainstay of treatment was palliative radiotherapy.

Aproximación al abordaje jurídico de la violencia letal contra mujeres trans en Colombia: Del feminicidio al transfeminicidio
Authors: Sánchez Avella César , Arévalo Mutiz Paula Lucía
Published: March 2021

El presente texto se aproxima al abordaje jurídico que se ha dado en Colombia a la violencia letal basada en la identidad de género, la cual ha sido tipificada como feminicidio (Ley Rosa Elvira Cely) y que, dada su especificidad, podría llegar a investigarse y sancionarse como transfeminicidio. Dada la consciencia alcanzada en el ámbito de los derechos humanos sobre la grave situación que enfrentan las mujeres transgénero en América Latina, específicamente en países como Colombia, importantes organizaciones LGBT han luchado por la adecuada judicialización de los crímenes perpetrados por motivo de la identidad de género. A diferencia de México y Argentina, en Colombia se ha hecho una interpretación amplia del tipo penal autónomo ‘Feminicidio’ para aplicarlo a los casos de asesinatos de mujeres trans, planteando grandes desafíos para su aplicación por parte de investigadores y operadores judiciales. Explorando posibles respuestas para la pregunta sobre la necesidad de ‘transitar’ hacia la creación de un tipo penal autónomo para el transfeminicidio, en este artículo de investigación se ofrece una introducción, que explora el contexto sociojurídico de esta problemática en Colombia, seguido de la metodología de la pesquisa adelantada, los antecedentes de la investigación, una discusión conceptual a la luz de autoras feministas y transfeministas desde una perspectiva latinoamericana, y los principales hallazgos sobre los avances, dificultades y desafíos del actual abordaje jurídico de este fenómeno. Se cierra el presente trabajo con algunas conclusiones y recomendaciones para futuras investigaciones en la materia.
