MULTI-LEVEL OCCLUSIVE-STENOTIC LESIONS OF THE MAIN ARTERIES OF THE INFRARENAL AORTA IN PATIENTS WITH ATHEROSCLEROSIS: ANALYSIS OF TREATMENT AND COMPLICATIONS
Authors: Shaprynskyi V. V.
Published: October 2022

Resume. The Aim. To analyze the effectiveness of surgical treatment and postoperative complications in patients with multilevel occlusive-stenotic lesions of the main arteries (MOSLMA) of the infrarenal aorta.

Materials and methods. The results of treatment and complications in 51 patients with (MOSLMA) of lower extremities, as a result of obliterating atherosclerosis, were analyzed. Of these, 42 (82.4 %) had two and 9 (17.6 %) three-level lesions. A total of 7 balloon angioplasties and 13 stentings were performed for two and three level lesions in which the iliac arterial segment was affected. Only balloon angioplasty was used for revascularization of the infrainguinal segments.

Results and discussion. In general, regression of ischemia was achieved in 48 (94 %) patients. Of the complications in the early postoperative period, retrombosis was diagnosed in 6 patients. In 3 of them, the limb was saved by thrombolytic therapy and angioplasty. The other 3 patients underwent limb amputation. Mortality in the early postoperative period was 3.9 % (2 patients died as a result of myocardial infarction). An example of successful treatment of a patient with (MOSLMA) and previously stented superficial femoral artery is given.

Conclusions. Patients with (MOSLMA) are a complex category with predominantly aggravated comorbidity. The optimal method of revascularization is endovascular. Arterial puncture under ultrasound guidance helps to reduce complications such as hematomas and false aneurysms. The introduction of a clear algorithm based on preoperative assessment of anatomical and hemodynamic lesions of the arteries, taking into account the severity of the patient’s condition, can give good treatment results.
PSYCHOEMOTIONAL INDICATORS OF PATIENTS WITH PURULONECROTIC COMPLICATIONS OF THE DIABETIC FOOT SYNDROME WHO USED DEVICE FOR OFFLOADING OF FOOT DURING MARTIAL LAW
Authors: Pryimenko D. S.
Published: October 2022

Abstract. Aim. To study the psychoemotional state of patients with purulent-necrotic complications of diabetic foot syndrome (DFS), who used the device for offloading of foot developed by us during the martial law in Ukraine and to compare it with the results of health-related quality of life indicators in peacetime.

Materials and methods. All operated patients had stage 3 or 4 of the pathological process on the foot according to the Meggitt-Wagner classification, a neuroischemic form of DFS. The first group includes 28 patients who received prescribed treatment before the introduction of martial law in the country; the second group – 24 patients who were treated during martial law. The psychoemotional state of patients with purulent-necrotic complications of DFS was studied on the 1st and 20th days using the «Emotions» subscale from the «Illness Impact Profile» questionnaire; index of general (good) well-being/ WHO, version 1999; hospital anxiety and depression scale.

Results and discussion. The indicators of patients of the first group according to the subscale «Emotions» on the 1st day — (85.7±14.3) points, and of the second group — (104.6±16.1) points. In the group of patients who were interviewed before martial law, the result of the general well-being index was (48.4±1.2). Patients of the second group have (43.5±1.1). Anxiety level: (7.5±0.3) points and (8.7±0.4) points; level of depression: (6.4±0.5) points and (7.6±0.4), respectively. Although the indicators remain unsatisfactory on the 20th day, the tendency towards the improvement of the psychoemotional state is already becoming obvious. The difference in indicators between the two groups remains, which is explained by the influence of military events.

Conclusions. In the second group, worse indicators were found for the psychoemotional component of health-related quality of life, both on the 1st and 20th days. The worse dynamics of the improvement of the specified indicators on the 20th day were recorded. In the first group, according to the «Emotions» subscale, there was an improvement of 63.1 %, in the second group — by 36.2 %; the general well-being index increased by 40.1 % and 25.1 %, respectively. If in the first group, the anxiety index decreased by 16 %, and depression by 20.3 %, then in the second group, the anxiety index decreased by 12.6 %, and depression — by 10.6 %.

Authors: Fariha Muzammil  , Huda Abbas  , Shazia Naz  , Hamza Muzammil  , Wajahat Hussain
Published: October 2022

BACKGROUND & OBJECTIVE: Hypomagnesemia has a detrimental influence on glucose homeostasis and insulin sensitivity in T1DM andT2DM patients, as seen by the progression of DM comorbidities such as arterial atherosclerotic(atherosclerosis), retinopathy, and nephropathy. The objective of this study is to make a comparison and correspond biochemical variants(to analyze the difference) of fasting blood glucose, serum magnesium, and major lipid analytes (serum total cholesterol and triacylglycerol) in diverse medical groups of both T1DM and T2DM.

METHODOLOGY: It was a cross-sectional observational study carried out at Sahiwal teaching hospital, Sahiwal, Pakistan, including 250 research participants. The study used a traditional time-bound sample size of 6 months starting from first March to August 2021through a random selection approach.

RESULTS: Out of 250 participants, 200(80%) of whom(omit) had diabetes mellitus (DM), The number of men with diabetes 110(55%) was greater than the percentage of women with diabetes 90(45%) in this study. 52(26%) of the research participants had T1DM, whereas 148 (74%) had T2DM. A comparison of plasma glucose levels of the three groups was made, and the difference(added) was statistically significant. The difference(added) in serum magnesium, serum total cholesterol, and serum triglycerol among the groups(added) was also statistically significant p<0.05.

CONCLUSION: The current study looked at hypomagnesemia biochemical changes in overt hyperglycemic-hyperlipidemic clinical groups of T1DM and T2DM. In light of the reviewed research findings, it is recommended that serum magnesium can be measured as a routine or extended diagnostic profile investigation in recognized health cases of T1DM and T2DM for early screening, periodic monitoring for deficiency, and better management of clinical cases through supplementation to prevent the development of long-term critical diabetes complications.

Authors: Zainab Tehreem  , Yasir Kazmi  , Muhammad Usman Khalid  , Haroon Mansha  , Muhammad Hassan  , Rabia Majeed
Published: October 2022

BACKGROUND & OBJECTIVE: Post-burn contracture is the tightening of the skin after a second or third-degree burn with the formation of contracture. Post-burn contractures result in the limitation of movement around a burn area. Burns contractures, if left untreated, may cause limitations in the range of motion and daily living tasks. The purpose of this study was to compare the effects of soft tissue mobilization versus static stretching in post-burn contractures at the elbow and wrist.

METHODOLOGY: A pilot study was conducted, and 36 patients were enrolled. Patients with post-burn contracture were divided randomly into two groups. Allocation of patients in both groups was done by computerized generated list. The treatment frequency was 3 times a week. Numeric pain rating scale (NPRS) and Katz index ADLS scale were used for scoring. Paired t-test was applied to evaluate the data.

RESULTS:  The mean age in group A and B were 26.16±7.46 and 28.05±1.27, respectively. Mean score for pre-Katz Index of Group A and B (2.47±0.87, 2.16±0.98), post-Katz Index group A and B (3.29±1.68, 3.05±1.47) with a p-value 0.12 and 0.03 group A and B respectively. The mean score group A and B for pre-NPRS (7.61±1.37, 7.94±1.10), post-NPRS (2.27±1.01, 1.72±1.22) with a p-value<0.001 .

CONCLUSION: It was concluded that static stretching is more effective than soft tissue mobilization.

Published: October 2022

The purpose of this study was to identify the characteristics of parenting-related psychological factors and to identify factors affecting turnover intentions of nurses with preschool children. The subjects were 122 nurses working in 3 general hospitals located in Seoul and Gyeonggi-do, and data collection was conducted from November 1 to December 30, 2019. Data were analyzed by descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, and multiple regression. As a result of the study, the mean score of parenting self-efficacy, parenting guilt and turnover intention were 3.18(SD=0.48), 3.27(SD=0.63), 3.02(SD=0.70), respectively. Turnover intention showed a significant difference according to career, work type, and number of preschool children. Turnover intention was significantly correlated with parenting self-efficacy and parenting guilt. It was confirmed that the turnover intentions of nurses with preschool children was affected by work type, number of preschool children, and parenting guilt. The shift work(β=.163, p=.017), the number of preschool children more than 2(β=.280, p<.001), and the higher the parenting guilt were the higher the turnover intention. Based on the results of this study, in order to reduce the resignation of nurses with preschool children, it is necessary to introduce various types of work in hospitals and to activate daycare centers at work that can be used regardless of work type. In addition, the development and application of psychological support programs should be considered in order to lower the guilt about parenting and to have psychological stability.
Cohesive Devices on the Abstracts of Select Research Articles Presented in the International Academic Forum (AIFOR): A Discourse Analysis
Authors: Cabrejas Maribeth Mr.
Published: October 2022

This linguistic research analysis investigates the cohesive devices found in the Abstract of select Asian Conference of Education 2019 research articles. This study also endeavors to disclose the contributions of the cohesive devices in the comprehensibility of the text. This corpus-based study utilizes qualitative descriptive research that specifically employs the evocative discourse analysis. It considers the use of Halliday and Hassan’s taxonomy on Cohesive devices as a basis for investigation. A total of twenty-eight (28) research abstracts are chosen from abstracts compiled in the program and abstract book of the Asian Conference on Education (ACE) presented during the International Academic Forum (IAFOR) held in Toshi Hotel, Tokyo, Japan last October 31 to November 3, 2019, as the main source of data. The data are analyzed using Halliday and Hasan’s taxonomy of cohesion which is divided into two aspects, grammatical and lexical cohesion. The result of the study reveals that researchers utilize two grammatical cohesions namely: reference and conjunctions in their research abstracts. The conjunctive features of the grammatical device found are additive, causal, adversative, and temporal. Moreover, the referential grammatical devices found are demonstrative, personal, article, and comparative.  There is no usage of substitution and elliptical cohesion or ellipsis found. In terms of lexical cohesion, Reiteration devices such as repetition, synonymy, and antonymy are utilized by the researchers in their abstracts. There is no evidence of meronomy found in the analysis. Collocation devices are widely used in the abstract. In the analysis, the presence of the cohesive devices in the abstracts functions to keep track of the participants, organized in logical order the concepts in the abstract, and help in avoiding repetition and text redundancy which significantly contributes to the text comprehensibility of the research abstracts. Thus, the researcher designs and presents an English workbook for classroom use in which the drills provided focus on the correct usage of cohesive devices in any written discourse.

Modern Languages and/as Area Studies: Towards a New Humanities or Path to Oblivion?
Authors: Hutchings Stephen
Published: October 2022

There is an ambivalence regarding the traditional disciplinary affiliation of Modern Languages, split between Area Studies, with its orientation to the social sciences, and an arts wing aligned with literary and cultural studies. The Area Studies contingent has itself been hampered by its struggle to convince social scientists that linguistic expertise is anything more than a practical tool enabling them to extend their research agendas to non-English speaking environments. My article will argue that the apparent incoherence highlighted by this double tension provides an impulse for Modern Linguists to renew their discipline by forging a more equal partnership with the social sciences and enhancing their significance within the humanities. It focuses on the renewed social scientific interest in spatio-temporal situatedness, contending that language’s critical role in the lives of humans as spatio-temporally embodied beings can transform linguistic expertise from a mere facilitating skill into the intellectual core of a reconceived New Area Studies (NAS). It will demonstrate how, freed from Cold War geopolitics and from its attachment to the Great Power as its primary unit of analysis, NAS rejects the very notion of areas as bounded entities, privileging what ‘flows through’ them (media, artistic forms, images and knowledge, as well as people) over what is ‘in’ them. I will discuss what this means for the future of Modern Languages in the academy, concluding that the discipline’s ability to operate across multiple boundaries in this context gives it the power to reassert itself in the forefront not just of NAS, but of a revitalised humanities more generally.
Podcasting Collaborations and Ontological Relationships of Being ‘Here’ and ‘There’ in the Lower Marañón River in Peru
Authors: Ulfe María Eugenia , Vergara Roxana
Published: October 2022

This article is about podcasts and mobile phones not only as “daily technologies of life” but also as ways to convey personal stories and to do ethnographic research. However, we do not romanticize the use of digital technology for anthropological research. We use podcasts as a form to write our ethnographic work with our collaborators, and also as a way to keep in contact with our collaborators while in a global pandemic. For podcasts, we had to do several interviews and later edited them as both dialogues and individual stories. Interviews were mostly done by other digital devices such as WhatsApp, Facebook messenger, and telephone calls. The stories in our podcast series are mostly about an Amazonian indigenous community struggling to survive the global pandemic after several oil spills and other epidemics. Podcasts create a sort of intimacy and co-presence stimulating a multimodal, sensorial experience. However, power relations do not disappear, nor did they become invisible. Rather, power relations are accommodated in the new audio/digital scenario.
Blurring Genres: A Personal Narrative About University Management
Authors: Rhodes R. A. W.
Published: October 2022

Blurring genres involves a shift from naturalist social science to the analogies of game, drama and text. This article combines ethnography, autobiography, literature, and political science to roam the realms of personal narratives or autoethnography. It explores genres of thought and of presentation not commonly found in political science in a story about university management. A personal narrative involves using self-reflection to explore anecdotal and personal experience, and connecting this story to wider cultural, political, and social meanings and understandings. Commonly, autoethnographies are evocative; that is, they seek to persuade readers that they know these people and have been to these places. Here, I offer an analytic personal narrative; it is storytelling that seeks to marry idiographic particularity with an analysis that speaks to large issues. I present autobiographical material about my academic career as an ‘artificial person’. I use this story to invite the reader to engage with the big issue of the role of the university in Britain today. Finally, I offer some topics for the readers’ ‘consideration’, identifying several personal considerations as well as considerations for political science, and for universities. Although writing personal narratives challenges the conventional canons of social science research about transparency and reliability of data, it also offers an innovative way of understanding the self in the world.

Congelamiento de semillas: Una alternativa para la conservación de germoplasma de café
Authors: Acuña-Zornosa Ricardo
Published: October 2022

El germoplasma de café es la materia prima del mejoramiento genético para el desarrollo de variedades con buenos atributos agronómicos, resistentes a la roya y de excelente producción y calidad en taza. En Cenicafé existe un banco de germoplasma conocido como la Colección Colombiana de Café (CCC), que contiene la diversidad genética para afrontar los retos agronómicos del cultivo. La CCC se conserva en el campo por lo que está expuesta a riesgos de pérdida de sus componentes debido a plagas, enfermedades, condiciones climáticas adversas o problemas de adaptabilidad. Para mitigar este riesgo, el germoplasma también podría conservarse como un banco de semillas, pero no usando los métodos convencionales de deshidratación, debido a que las semillas del café no pueden ser almacenadas por más de un año. En este seminario se mostrarán los resultados de la validación de un método de conservación de semillas de Coffea sp. a una temperatura de -196°C, lo que posibilitaría crear un banco de semillas de la CCC como alternativa a la colección de campo.

Evidence of Long-term Period Variations in the Exoplanet Transit Database (ETD)
Authors: Hagey Simone R. , Edwards Billy , Boley Aaron C.
Published: October 2022

We analyze a large number of citizen science data and identify eight hot Jupiter systems that show evidence for deviations from a constant orbital period: HAT-P-19 b, HAT-P-32 b, TrES-1 b, TrES-2 b, TrES-5 b, WASP-4 b, WASP-10 b, and WASP-12 b. The latter system is already well known to exhibit strong evidence for tidal orbital decay and serves as an important control for this study. Several other systems we identify have disputed period drifts in the literature, allowing the results here to serve as an independent analysis. The citizen science data are from the Exoplanet Transit Database (ETD), which is a global project established in 2008 by the Variable Star and Exoplanet Section of the Czech Astronomical Society. With over 400 planets and 12,000 contributed observations spanning 15 yr, the ETD is brimming with potential for studying the long-term orbital evolution of close-in hot Jupiters. We use our results to discuss prioritization of targets for follow-up investigations, which will be necessary to confirm the period drifts and their causes.
Search for an Alien Message to a Nearby Star
Authors: Gillon Michaël , Burdanov Artem , Wright Jason T.
Published: October 2022

If alien probes have colonized the whole galaxy, they could have formed an efficient galactic-scale communication network by establishing direct gravitationally lensed links between neighboring systems. Under this scenario, observing the positions opposite the nearest ecliptic stars represents a promising artifact SETI strategy that could make it possible to “eavesdrop” on the emission of local probes to one of these stars. In this context, we present here a first attempt to detect optical messages emitted from the solar system to the ecliptic star Wolf 359, the third-nearest stellar system, based on observations gathered by the TRAPPIST-South and SPECULOOS-South robotic telescopes. While sensitive enough to detect constant emission with emitting power as small as a few watts, this search led to a null result. We note that the putative alien probes could be emitting “off-axis” and be located much closer to the Sun than the start of the “solar gravitational line” at 550 au. We performed a search for such an off-axis emitter in our data, whose result turned out negative too.

We report spectropolarimetric observations of the Type Ia supernova (SN) SN 2021rhu at four epochs: −7, +0, +36, and +79 days relative to its B-band maximum luminosity. A wavelength-dependent continuum polarization peaking at 3890 ± 93 Å and reaching a level of

% was found. The peak of the polarization curve is bluer than is typical in the Milky Way, indicating a larger proportion of small dust grains along the sight line to the SN. After removing the interstellar polarization, we found a pronounced increase of the polarization in the Ca ii near-infrared triplet, from ∼0.3% at day −7 to ∼2.5% at day +79. No temporal evolution in high-resolution flux spectra across the Na i D and Ca ii H and K features was seen from days +39 to +74, indicating that the late-time increase in polarization is intrinsic to the SN as opposed to being caused by scattering of SN photons in circumstellar or interstellar matter. We suggest that an explanation for the late-time rise of the Ca ii near-infrared triplet polarization may be the alignment of calcium atoms in a weak magnetic field through optical excitation/pumping by anisotropic radiation from the SN.
On the Convergence of the Milky Way and M31 Kinematics from Cosmological Simulations
Authors: Forero-Romero J. E. , Sierra-Porta D.
Published: October 2022

The kinematics of the Milky Way (MW) and M31, the dominant galaxies in the Local Group (LG), can be used to estimate the LG total mass. New results on the M31 proper motion have recently been used to improve that estimate. Those results are based on kinematic priors that are sometimes guided and evaluated using cosmological N-body simulations. However, the kinematic properties of simulated LG analogs could be biased due to the effective power spectrum truncation induced by the small size of the parent simulation. Here we explore the dependence of LG kinematics on the simulation box size to argue that cosmological simulations need a box size on the order of 1 Gpc in order to claim convergence on the LG kinematic properties. Using a large enough simulation, we find M31 tangential and radial velocities relative to the MW to be in the range

A transient biological fouling model for constant flux microfiltration
Authors: Luongo Vincenzo , Mattei Maria Rosaria , Frunzo Luigi , D'Acunto Berardino , Gupta Kunal , Chellam Shankararaman , Cogan Nick
Published: October 2022

Microfiltration is a widely used engineering technology for fresh water production and water treatment. The major concern in many applications is the formation of a biological fouling layer leading to increased hydraulic resistance and flux decline during membrane operations. The growth of bacteria constituting such a biological layer implicates the formation of a multispecies biofilm and the consequent increase of operational costs for reactor management and cleaning procedures. To predict the biofouling evolution, a mono-dimensional continuous free boundary model describing biofilm dynamics and EPS production in different operational phases of microfiltration systems has been well studied. The biofouling growth is governed by a system of hyperbolic PDEs. Substrate dynamics are modeled through parabolic equations accounting for diffusive and advective fluxes generated during the filtration process. The free boundary evolution depends on both microbial growth and detachment processes. What is not addressed is the interplay between biofilm dynamics, filtration, and water recovery. In this study, filtration and biofilm growth modeling principles have been coupled for the definition of an original mathematical model able to reproduce biofouling evolution in membrane systems. The model has been solved numerically to simulate biologically relevant conditions, and to investigate the hydraulic behavior of the membrane. It has been calibrated and validated using lab-scale data. Numerical results accurately predicted the pressure drop occurring in the microfiltration system. A calibrated model can give information for optimization protocols as well as fouling prevention strategies.

Pharmaceutical care is the core of pharmacy practice. The reform and development of this practice are essential for the optimization of patient care and improvement of population safety. While pharmaceutical care has been established to have a long history in Nigeria, the implementation of the practice in Nigeria's tertiary health system is very limited and, in some regions, non-existent. Challenges such as knowledge deficits of pharmacists and the inadequacy of practice guidelines, a lack of knowledge, support, and an enabling environment to foster inclusiveness, limited access to patient records, the absence of documentation of interventions and the paucity of policy support and implementation, among others, stall pharmaceutical care provision in Nigeria's tertiary institutions. Here, we recommend that improving the interprofessional environment through collaboration, adequate regulations and policy development, the design of insurance and health support, pharmacy education, training and research optimization will bolster the pharmaceutical care practice in Nigerian tertiary hospitals. Moving the practice of pharmaceutical care in Nigerian tertiary hospitals requires transformational change and strategic collaboration among the pharmacists and health community.

Some components of the knowledge and skills required for teaching using 21st century technology can be assessed with reasonable confidence. The researcher conducted a study intended to determine the factors that affect teacher self-efficacy—that is, their evaluation of their own competence using the interactive educational website Wikispaces Classroom in various teaching fields. The participants were 44 pre-service teachers from various levels of the education system. The study was based on qualitative and quantitative methods. To obtain the qualitative data, the researcher administered a pre-survey and post-survey to measure the teachers' self-efficacy beliefs regarding the integration of the interactive website at the initial use and after or teachers and asked them to clarify their perspectives on how high self-efficacy had affected their use of the interactive website. The researcher distributed a questionnaire to uncover these factors. The findings showed how the use of the technology affected the teachers' self-efficacy in their use of the interactive learning website.

O objetivo deste estudo foi analisar, comparativamente, o nível da síndrome de Burnout em professores que trabalham em cursos de Ciências Contábeis nos níveis de graduação e pós-graduação stricto sensu. Com base na literatura prévia, que reporta que professores de pós-graduação stricto sensu estão submetidos a altas demandas de atividades que podem prejudicar sua saúde, especialmente aquelas relacionadas à pesquisa, formularam-se duas hipóteses: (H1) a atuação nos programas stricto sensu possui relação positiva com a síndrome de Burnout; e (H2) a carga horária destinada à atividade de pesquisa possui relação positiva com a síndrome de Burnout. Para tanto, aplicou-se questionário on-line com professores de Ciências Contábeis de Instituições de Ensino Superior do Brasil, obtendo-se 187 respostas. Foi usado o instrumento de Gil-Monte, Carlotto e Câmara (2010), cuja mensuração do Burnout se dá por meio de quatro dimensões: ilusão pelo trabalho (IT), desgaste psíquico (DP), indolência (ID) e culpa (CP). Os resultados dos modelos de regressão indicaram que não há diferença estatisticamente significante dos níveis de prevalência de Burnout entre docentes que atuam e não atuam em programa de pós-graduação stricto sensu em contabilidade, rejeitando a H1. Por outro lado, ao considerar a carga horária destinada a atividades de pesquisa, constatou-se que, de forma geral, há relação positiva com os níveis da síndrome de Burnout. Mais especificamente, em relação às dimensões DP, ID e CP. Essas evidências sustentam a hipótese H2. Os achados podem contribuir, principalmente, na elaboração de políticas e práticas educacionais e de saúde que apoiem o bem-estar dos professores.

Esta pesquisa objetiva analisar a eficiência econômica das capitais brasileiras na alocação do gasto com ações e serviços públicos de saúde no período de 2006-2015. Por meio da Análise Envoltória de Dados com retornos variáveis de escala e orientação para outputs, identificaram-se as capitais eficientes no período, as variações de produtividade e o conjunto de referência para as ineficientes. Os resultados revelam que dez capitais foram eficientes em todos os períodos, e apenas duas capitais foram eficientes em apenas um ano. As capitais que tiveram os melhores escores de eficiência tiveram os menores gastos per capita. Do conjunto de benchmarks, 57% das indicações ficaram concentradas em cinco capitais das regiões Norte e Nordeste. Conclui-se que o desempenho médio das capitais foi satisfatório, embora a variação de produtividade no período tenha sido insuficiente em alguns casos. No entanto, há um longo caminho para alcançar a máxima eficiência, obter maior produtividade e proporcionar maiores níveis de bem-estar social.

Published: October 2022

Este trabalho analisa o efeito da tenure da firma e sócio de auditoria no gerenciamento de resultados por accruals e por atividades operacionais reais das empresas abertas do mercado brasileiro. Compuseram a amostra 147 empresas, totalizando 1.138 observações para o período 2011-2019. O gerenciamento de resultados utiliza modelos por accruals discricionários e por atividades operacionais reais que constam nos trabalhos de Dechow, Sloan e Sweeny (1995) e Dechow, Kothari e Watts (1998), respectivamente. As regressões em painel por efeito fixo revelam que a tenure da firma de auditoria influência positivamente o gerenciamento de resultados por accruals discricionários. Já no nível da pessoa física, o resultado foi diferente, uma vez que a tenure do sócio de auditoria não se mostrou relacionada com o gerenciamento de resultados por accruals. Os achados também indicam que a tenure da firma e sócio de auditoria não estão relacionadas com o gerenciamento de resultados por atividades operacionais reais. Os resultados contribuem no âmbito prático, especialmente, em discussões dos órgãos reguladores, pois revelam evidências sobre o efeito da tenure do auditor em propiciar o aumento de ações oportunistas dos gestores.

Non motor symptoms (NMS) of Parkinson’s disease (PD) lead to morbidity, impaired quality of life and frequent hospitalization. NMS are under-recognized and under-reported. NMS Quest is a validated screening tool adopted to identify these symptoms in patients with PD. We conducted a descriptive cross sectional study during March 2012 – September 2012 in a tertiary care hospital in Sri Lanka to describe the non-motor symptoms of PD and to determine the percentage of NMS that remain undeclared to the healthcare professionals. 103 patients, age 64.55 (SD 9.62, range 43-86) years, 58 (56.3%) males and 45 (43.7%) females completed the study. Mean duration of illness was 3.16 yrs. 98.1% of patients had at least one NMS. The mean total NMSQ-T was 9.08 +/- 5.087(SD). Memory loss was the commonest NMS. NMSQ-T increased with the severity of PD (p<0.001) but no association was found between NMSQ-T and age, sex or duration of illness. Loss of weight, difficulty in swallowing and falls were significantly commoner among males than females. (p <0.05) A significant proportion of NMS (Mean 76.1 +/- 17.7, range 36.7% to 100%) were undeclared to the health care personnel. Incomplete bowel evacuation, sweating, diplopia and anxiety were the least declared symptoms. In conclusion, NMS are present in the majority of patients with PD increasing with the severity of disease. A significant proportion of NMS are undeclared to the healthcare personnel highlighting the importance of using screening tools to identify these symptoms during health visits.

Published: October 2022

Objective: To determine whether there was an improvement in stroke care after the establishment of the Stroke Unit at the Institute of Neurology, National Hospital of Sri Lanka. Design: The process of acute stroke care was evaluated by retrospective case record analysis of 192 patients with stroke admitted to the Stroke Unit. These results were compared with a previous audit of 263 patients treated in the neurology wards. The two audits used identical methodology, and were conducted using an audit package developed by the Royal College of Physicians of London. Methods: Sixty audit items related to stroke care were assessed, and compared between the two audits. Performance for each item was recorded as a percentage, and was graded from ‘very poor’ to ‘very good’. The difference between the two audits for each item was expressed as an odds ratio (OR). Results: Care was graded as ‘very good’ or ‘good’ for 56.7% of audit items, compared to 20% in the first audit. Significant improvements in care (OR>1.0, p<0.05) were noted in 50 out of the 60 audit items. Large improvements were seen in assessment of risk factors, CT scanning, rehabilitation oriented clinical assessments and initiation of secondary preventive measures. Conclusion: Establishment of the Stroke Unit has led to significant improvements in the process of stroke care.
