ABSTRACT Purpose: restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgical procedure of choice in some cases of familial adenomatous polyposis (FAP) and ulcerative colitis (UC). IPAA allows complete removal of the diseased colon and rectum, however, it is associated with substantial morbidity and potential consequences to patients’ quality of life (QoL). Aims: to evaluate the surgical results, functional outcomes and QoL after IPAA; and to examine the impact of surgical complications upon QoL. Methods: we reviewed the records of 55 patients after IPAA, with emphasis on surgical outcomes. Forty patients answered the questionnaires. The Cleveland Global Quality of Life (CGQL), Inflammatory Bowel Disease Questionnaire (IBDQ), and Short Form 36 Health Survey Questionnaire (SF36). Results: the average age was 42.1±14.1 years. 63.6% of the patients were male, and 69.1% had FAP. Operative mortality was 1.8% and overall morbidity was 76.4%. Anastomotic leakage was the most frequent early complication (34.5%). Pouchitis (10.8%) and small bowel obstruction (9.1%) were the most common late complications. Patients with UC had the most severe complications (p=0.014). Pelvic complications did not have a negative effect on functional outcomes or QoL scores. Female patients had decreased pouch evacuation frequency, fewer nocturnal bowel movements, decreased bowel symptom impact on QoL (p=0.012), and better CGQL (p=0.04). Patients with better education had better QoL scores, and patients who had their pouches for more than five years scored lower. Conclusion: the high morbidity has no impact on function or QoL. Bowel function is generally acceptable. QoL is good and affected by sex, education and time interval since IPAA.

RESUMO O objetivo desta pesquisa foi compreender como ocorre o processo de open strategizing frente à incerteza percebida pela turbulência do ambiente causada pela pandemia do COVID-19. Nesse contexto de crise, a forma como ocorre a abertura da estratégia é impactada pelas ações corretivas imediatamente necessárias. Foi realizado um estudo de caso em uma organização que presta serviço não essencial e sofreu impactos diretos, precisando alterar repentinamente suas estratégias, operando com limitações e seguindo as recomendações dos decretos governamentais. A coleta de dados foi por meio de entrevistas, observação direta e análise de documentos. A partir da análise de narrativa e comparação de padrões teóricos/empíricos dos dados, encontramos que o processo de open strategizing ocorre de forma integradora; as decisões ocorrem no sentido middle-up-down, integrando pessoas, estrutura e estratégia de maneira não linear ou estruturada, com adoção de algumas práticas de inclusão e transparência da informação no momento em que o fenômeno estava se desenvolvendo em larga escala, em nível mundial. A pandemia segue em evolução, e as incertezas predominam no contexto global e local desafiando a tomada de decisão enquanto esta pesquisa acontece.

RESUMO Muitos agentes atuantes nas bolsas de valores são relutantes em realizar perdas e têm maior facilidade em realizar ganhos, comportamento chamado de “efeito disposição”. Tais agentes podem ser individuais ou institucionais, esses últimos considerados mais racionais em suas tomadas de decisão. Assim, este artigo buscou analisar se existem diferenças quanto à presença do efeito disposição na tomada de decisões financeiras entre investidores individuais e institucionais. A amostra compreendeu transações realizadas por investidores individuais e institucionais, entre janeiro de 2012 e 31 de outubro de 2014, com dados reais de três ações obtidos na bolsa de valores brasileira, sendo aplicada uma metodologia específica para detectar o efeito disposição. Resultados mostraram que o efeito disposição está presente em todas as análises para os investidores individuais e em apenas algumas análises para os investidores institucionais, sendo mais forte para os investidores individuais. Isto indica que os investidores individuais são mais enviesados pelo efeito disposição do que os investidores institucionais. Ademais, a média dos retornos das aplicações dos investidores institucionais foi maior do que as realizadas por investidores individuais, mostrando que os investidores institucionais alcançam melhores retornos em suas aplicações.

ABSTRACT Objective To reflect on the understanding of financial toxicity, as an adverse event of cancer diagnosis and treatment, and its implications on the quality of life of these patients. Method Reflexive study, based on the international literature about the concept of financial toxicity and its relationship with quality of life. Results Financial toxicity is related to the financial difficulties associated with cancer and its treatment, which occur in the lives of patients and family members. Its consequences include: possible worsening of the clinical symptoms, indebtedness, loss of professional opportunities, changes in family habits and decline in quality of life. Final considerations Measures to minimize financial toxicity should also be a concern of the state and be part of the therapeutic itinerary of cancer patients. Dialogue can become an essential tool for the health team to clarify the therapeutic options and their costs. This attitude shows respect and preserves the patient’s autonomy, which can minimize the feeling of helplessness in the face of the disease.

Published: March 2021

Abstract Emphysematous pyelonephritis (EPN) is a rare acute necrotizing infection of the kidney and surrounding tissues, with gas in the renal parenchyma, collecting system or perirenal tissue. The bacterial etiology predominates; mainly Gram-negative bacilli; Candida spp. and C. albicans are rarely described. We describe a case of EPN caused by C. glabrata, sensitive to fluconazole in a young, hypertensive woman with undiagnosed diabetes mellitus (DM), with renal dysfunction upon admission; her abdominal CT scan found a volumetric increase in the left kidney, signs of gas collections and perirenal blurring. Despite the antimicrobial therapy instituted, due to clinical refractoriness, a double J catheter and subsequent total nephrectomy were indicated, with good postoperative evolution. Her uroculture showed C. glabrata sensitive to fluconazole, and the pathology study showed tubular atrophy and intense interstitial inflammatory infiltrate. Despite the serious, potentially fatal condition, we could control the infection and the patient recovered fully. Poor DM management is an important triggering factor, and it is of great relevance to identify the EPN through imaging exams due to the peculiarities of its clinical and potentially surgical management

RESUMO Objetivou-se caracterizar a exposição humana à infecção por bactérias e vírus via ingestão, considerando os cenários: tratamento do lodo (cenário 1); uso do lodo como adubo agrícola (cenário 2) e consumo de hortaliças adubadas com lodo (cenário 3). A exposição foi caracterizada pelas concentrações de Escherichia coli, vírus entéricos cultiváveis (VEC) e colifagos somáticos (CS) nas amostras: lodo de esgoto em tratamento (LET), água de lavagem das mãos (ALM) no tratamento e no plantio, mistura solo + lodo (MSL) e hortaliças alface e cenoura. No cenário 1, em torno de 50-60 dias, as amostras LET apresentaram umidade < 10% e padrão classe A. Nas amostras LET, concentrações de CS variaram entre 9,1 × 102 e 1,9 × 105 UFP.g-1 ST e de VEC entre 2,42 e 7,15 UFP.g-1 ST. No cenário 2, CS foram detectados em 72% das amostras MSL com concentrações entre 10 e 330 UFP.mL-1. Concentrações de E. coli ≤ 102 NMP.100 mL-1 foram detectadas nas amostras ALM-tratamento (63,7%). Para vírus, todas as ALM-tratamento foram negativas e 17,4% das ALM-plantio apresentaram VEC entre 3 e 409,2 UFP.mL-1. Todas as amostras de alface foram negativas para CS e VEC. Considerando-se as características dos cenários avaliados, trabalhadores do serviço de saneamento, trabalhadores rurais e consumidores de hortaliças estiveram expostos a baixas concentrações de E. coli e VEC. CS foram resistentes ao tratamento térmico e ao plantio, o que sugere seu potencial como indicadores de VEC.

A növekvő időjárási szélsőségek ismerete nemcsak a klíma változása miatt fontos, hanem a természetben, azaz erdőkben lezajló ökofiziológiai folyamatok alaposabb megértése miatt is. Az erdőket is érintő időjárási szélsőségek monitorozására, nyomon követésére a legalkalmasabb egy olyan meteorológiai merőhálózat létesítése, üzemeltetése, amely elsősorban magas erdősültséggel rendelkező területeken mér és gyűjt adatokat. Az Erdészeti Tudományos Intézet 18 GPRS rendszerű meteorológiai állomást üzemeltet folyamatosan törekedve az országos lefedettségre. A mért adatok feldolgozása során megállapítást nyert, hogy az egyes klimatikus szélsőségek az átlagostól elérő időpontokban jelentkeznek az ország különböző pontjain. Több alkalommal hosszú aszályos időszakok voltak megfigyelhetőek (pl.: 2019. március, április), amelyek magas hőmérsékleti értékekkel is párosultak. A meteorológiai monitoring párhuzamosan futó talajvízszint monitoring rendszer eredményei szintén jelentős különbségeket mutatnak a vizsgált mintaterületek vízháztartási folyamataiban.
THE CREMNA ARCHAEOLOGICAL RESEARCH-PROJECT IN CENTRAL PISIDIA: LAST SEASON FIELD STUDIES
Authors: METİN Hüseyin
Published: March 2021

The study area is located in a mountainous part of the central Pisidia Region of the ancient city of Cremna. It is a city that is difficult to be captured due to its geographical location. For this reason, it is the least affected by the political events in the 3rd century AD according to the surrounding cities. Cremna Researches have been conducted since 2013 in two groups as city-centered and rural area researches. The main reason for the research on this subject is to determine the cultural relations of Cremna by examining the settlements in rural areas as well as the socio-cultural, economic and political relations with the cities around it. The subject of this article is the archeological investigations of Cremna Researches between 2018 and 2019. In general, Cremna surveys are carried out within the borders of Hisarköy-Asartepe from the north, Evciyeri from the east, the Kapılı Cybele Monument from the west and the ancient city of Sia from the south. In the Cremna Researches in the last season, very important data have been added to the archeology literature. Prehistoric Cave settlements and the determination of the use of some caves as sanctuaries are very important discoveries. It was understood that both tower structures and rural settlements were built in sheltered topographic places for safe protection of rural areas from the Classical Period to the Roman Period. The data on the Byzantine and Ottoman periods show that the Cremna territorium has hosted many communities from the earliest times to the present day.
OSMANLI TARİHİ YAZIMINDA NÜFUS DEFTERLERİNİN YERİ: 1831 TARİHLİ TEKE LİVASINA BAĞLI ELMALI KAZASI NÜFUS DEFTERİ ÖRNEĞİ

Özet
Tahrirler dışında Osmanlı İmparatorluğunda XIX. yüzyıla gelinceye kadar herhangi bir nüfus sayımına rastlanmamaktadır. II. Mahmud Devrinde (1808-1839) hem tasarlanan reformların gerçekleştirilmesi hem de ihtiyaç duyulan modern bir ordunun tesis edilmesi için mali kaynak yaratılması gerekiyordu. Bu sebeple de öncelikle ülkedeki mevcut gelir kaynaklarının “eksiksiz” bir biçimde belirlenmesi ve de aynı zamanda askere alınabilecek nüfusun tespiti gerekmekteydi. İmparatorlukta 1830 senesinde bu amaca yönelik yalnızca erkek nüfusu kapsayan sayıma başlanmıştı. Sayımda görevli kimselerce ülkede yaşayan Müslim, gayrimüslim erkek nüfus kayıt altına alınmıştı.
Bu çalışmada Osmanlı İmparatorluğunda yapılan tahrirler ve nüfus sayımları hakkında genel bilgiler verildikten sonra Teke Livasına bağlı Elmalı Kazası’nda 1831’de yapılan nüfus sayımının kayıt altına alındığı defter örneğinden nüfus defterlerinin Osmanlı tarihi yazımındaki önemi açıklanmaya çalışılmıştır. Zira bu sayımlarda kayıt altına alınan idari birimdeki mahalleler, köyler ve burada yaşayan nüfus, yaşları, meslekleri, varsa lakapları, fiziksel özürleri vb. hususlar belirtilerek yazılmıştır. Böylece defterler bir köyde, kazada vs. yaşayan -erkek- nüfusun sayısı, yaş ortalaması, yaygın olan meslekler, iş kollarının tespit edilmesini ve böylece Osmanlı İmparatorluğunun sosyo-ekonomik tarihinin yazılmasında çok kıymetli veriler sağlamaktadır. Gene köy, mahalle isimleri ve bu isimlerin zaman içerisindeki değişimi takip edilebilmektedir ki bu ise idari tarih bakımından değerli verilerdir. Çalışmamızda yine örnek defter üzerinden bu değişim gösterilmeye çalışılmıştır.
THE EVALUATION OF THE CULTURAL TRANSMISSION THROUGH COURSE BOOKS TEACHING TURKISH & PERSIAN AS A FOREIGN LANGUAGE
Authors: GÜL Sara
Published: March 2021

Nowadays communication in foreign language learning gain prominence. Moreover, it is revealed that learning the grammatical structures and vocabularies are not sufficient to obtain proficiency in the language. Foreign language learning is a complex process involving not only the linguistic content but also the cultural norms of the target language. The inseparable relationship between culture and language divulges that mastering a language is impossible without learning the culture of that language. Consequently, the course books used for teaching a foreign language should promote communication abilities of learners via increasing the students’ cultural awareness.
This study aimed to evaluate “cultural transmission through teaching Turkish as a foreign language course books” versus teaching Persian as a foreign language. The evaluation of the “Learning Persian” book series and “Hitit course book 2” from the viewpoint of the cultural transmission divulged that both consist of factors that present Turkish and Persian cultures and succeed in transmitting their culture to learners. The subjects of course books represent the reality about the target culture. They are chosen from the authentic texts and basic real-life experience areas. Literature has considered very important in Persian learning book while environmental issues are emphasized in “Hitit” course book.

Published: March 2021

The article proposes an approach based on deep and machine learning models to predict a
component failure as an enhancement of condition based maintenance scheme of a turbofan
engine and reviews currently used prognostics approaches in the aviation industry. Component degradation scale representing its life consumption is proposed and such collected
condition data are combined with engines sensors and environmental data. With use of data
manipulation techniques, a framework for models training is created and models' hyperparameters obtained through Bayesian optimization. Models predict the continuous variable
representing condition based on the input. Best performed model is identified by detemining
its score on the holdout set. Deep learning models achieved 0.71 MSE score (ensemble
meta-model of neural networks) and outperformed significantly machine learning models
with their best score at 1.75. The deep learning models shown their feasibility to predict the
component condition within less than 1 unit of the error in the rank scale.
A tool wear condition monitoring approach for end milling based on numerical simulation
Authors: Zhu Qinsong , Sun Weifang , Zhou Yuqing , Gao Chen
Published: March 2021

As an important research area of modern manufacturing, tool condition monitoring (TCM)
has attracted much attention, especially artificial intelligence (AI)- based TCM method.
However, the training samples obtained in practical experiments have the problem of sample
missing and sample insufficiency. A numerical simulation- based TCM method is proposed
to solve the above problem. First, a numerical model based on Johnson-Cook model is established, and the model parameters are optimized through orthogonal experiment technology,
in which the KL divergence and cosine similarity are used as the evaluation indexes. Second,
samples under various tool wear categories are obtained by the optimized numerical model
above to provide missing samples not present in the practical experiments and expand sample size. The effectiveness of the proposed method is verified by its application in end milling
TCM experiments. The results indicate the classification accuracies of four classifiers (SVM,
RF, DT, and GRNN) can be improved significantly by the proposed TCM method.

We present a Hellenic database of intensity measures from uniformly processed strong ground motion recordings, together with metadata on earthquake source attributes and recording site conditions. The database consists of information from 471 earthquakes between 1973 and 2015 that produced 2993 usable recordings from 333 sites. A key element of this work is a unified presentation of data from two major data providers that operate in Greece (Institute of Engineering Seismology and Earthquake Engineering and the Institute of Geodynamics, National Observatory of Athens) along with a university-operated local urban array (University of Patras). Consistent procedures were applied to develop source parameters that include hypocenter locations, moment magnitudes (directly estimated or derived using a conversion procedure), fault-plane solutions, and finite-fault parameters (generally, for events with M>6.0). The time-averaged shear-wave velocity in the upper 30 m parameter is provided for all 333 recording sites based on geophysical measurements where available (102) and proxy-based estimates otherwise. Most events are in the magnitude range of 3.8–7, occurred at shallow hypocentral depths (<30  km), and provide data for rupture distances generally between 10 and 300 km. The combined ground motion, seismic source, and site database is anticipated to be useful for engineering applications, including ground-motion model development and time series selection for response-history analyses.
ARRU Phase Picker: Attention Recurrent-Residual U-Net for Picking SeismicP- andS-Phase Arrivals
Authors: Liao Wu-Yu , Lee En-Jui , Mu Dawei , Chen Po , Rau Ruey-Juin
Published: March 2021

Seismograms are convolution results between seismic sources and the media that seismic waves propagate through, and, therefore, the primary observations for studying seismic source parameters and the Earth interior. The routine earthquake location and travel-time tomography rely on accurate seismic phase picks (e.g., P and S arrivals). As data increase, reliable automated seismic phase-picking methods are needed to analyze data and provide timely earthquake information. However, most traditional autopickers suffer from low signal-to-noise ratio and usually require additional efforts to tune hyperparameters for each case. In this study, we proposed a deep-learning approach that adapted soft attention gates (AGs) and recurrent-residual convolution units (RRCUs) into the backbone U-Net for seismic phase picking. The attention mechanism was implemented to suppress responses from waveforms irrelevant to seismic phases, and the cooperating RRCUs further enhanced temporal connections of seismograms at multiple scales. We used numerous earthquake recordings in Taiwan with diverse focal mechanisms, wide depth, and magnitude distributions, to train and test our model. Setting the picking errors within 0.1 s and predicted probability over 0.5, the AG with recurrent-residual convolution unit (ARRU) phase picker achieved the F1 score of 98.62% for P arrivals and 95.16% for S arrivals, and picking rates were 96.72% for P waves and 90.07% for S waves. The ARRU phase picker also shown a great generalization capability, when handling unseen data. When applied the model trained with Taiwan data to the southern California data, the ARRU phase picker shown no cognitive downgrade. Comparing with manual picks, the arrival times determined by the ARRU phase picker shown a higher consistency, which had been evaluated by a set of repeating earthquakes. The arrival picks with less human error could benefit studies, such as earthquake location and seismic tomography.
Inversion for Shear-Tensile Focal Mechanisms Using an Unsupervised Physics-Guided Neural Network
Authors: Zhang Hongliang , Innanen Kristopher A. , Eaton David W.
Published: March 2021

We present a novel physics-guided neural network to estimate shear-tensile focal mechanisms for microearthquakes using displacement amplitudes of direct P waves. Compared with conventional data-driven fully connected (FC) neural networks, our physics-guided neural network is implemented in an unsupervised fashion and avoids the use of training data, which may be incomplete or unavailable. We incorporate three FC layers and a scaling and shifting layer to estimate shear-tensile focal mechanisms for multiple events. Then, a forward-modeling layer, which generates synthetic amplitude data based on the source mechanisms emerging from the previous layer, is added. The neural network weights are iteratively updated to minimize the mean squared error between observed and modeled normalized P-wave amplitudes. We apply this machine-learning approach to a set of 530 induced events recorded during hydraulic-fracture simulation of Duvernay Shale west of Fox Creek, Alberta, yielding results that are consistent with previously reported source mechanisms for the same dataset. A distinct cluster characterized by more complex mechanisms exhibits relatively large Kagan angles (5°–25°) compared with the previously reported best double-couple solutions, mainly due to model simplification of the shear-tensile focal mechanism. Uncertainty tests demonstrate the robustness of the inversion results and high tolerance of our neural network to errors in event locations, the velocity model, and P-wave amplitudes. Compared with a single-event grid-search algorithm to estimate shear-tensile focal mechanisms, the proposed neural network approach exhibits significantly higher computational efficiency.

Published: March 2021

the article defines the prerequisites for professional deformities of students: reduced depersonalization processes and distance in personal terms; average exhaustion of a psychoemotional and emotional nature; moderate general professional deformities; slightly below average reduction changes in the field of personal achievements and professional motivation. The features of ethnic tolerance of students with the prerequisites of professional deformities are revealed: low use of others as an example for imitation of forms of behavior and worldview positions; reduced tolerance to mental and physical discomfort caused by others; inability to control their unpleasant feelings caused by the low sociability of the interlocutors; moderate tolerance, in particular ethnic; reduced tolerance in interpersonal communication; below average degree of tolerance as a personal feature, as a component of effective communication; practical lack of desire to re-educate, remake others for themselves; reduced consideration of individual psychological characteristics of the interlocutors; low psychological flexibility in the process of evaluating others; reduced ability to adapt and forgive others. There is a noticeable relationship between: the average degree of severity of exhaustion of a psychoemotional nature and a reduced tolerance to mental and physical discomfort caused by others; the average level of general professional deformities and a low degree of severity of the use of others as an example for imitation of behaviors and worldview positions; average emotional exhaustion and a low level of ability to adapt and forgive others.

Ion Chromatographic Determination of Common Inorganic Anions in Tea Samples
Authors: CİTTAN Mustafa
Published: March 2021

A simple, rapid, and accurate technique based on ion chromatography coupled with a suppressed conductivity detector was described to determine the inorganic anions – fluoride, chloride, nitrite, bromide, nitrate, phosphate, and sulphate in tea bag samples. A Dionex IonPac AS9-HC 4×250 mm analytical column with a Dionex IonPac AG9-HC 4×50 mm guard column was used for the chromatographic separation of the analytes. The eluent was 12 mM KOH and the limit of quantification for the inorganic anions were in the range 0.02 - 0.20 mg L-1. Tea infusions were prepared traditionally by pouring the tea bags with 200 mL of boiling ultra-pure water. Influence of the brewing time on the extraction of inorganic anions from the tea bags was examined and optimum brewing time was determined as 6 min according to the results obtained. Finally, the ion chromatographic technique was applied to analyze the inorganic anions in some black, green, and white tea bag samples and five anions were determined quantitatively. The nitrite and bromide amount in all the samples were well below the quantification limit of the method.

Background: This study aimed to assess the admission pattern and outcome of neonates managed in the neonatal intensive care unit (NICU) in a Sudanese hospital.Methods: This hospital-based retrospective study was conducted in the NICU of Saad Abu Elella Teaching Hospital in Khartoum, Sudan. Data was collected from medical records of 207 neonates using an extraction form. Chi-square test and binary logistic regression were used in analysis.Results: Most of the neonates were term, and 43% of them had a birth weight less than 2.5 kg. Moreover, the most common morbidities among them were sepsis, respiratory distress syndrome, neonatal jaundice and asphyxia, and the mortality rate was 15%. Additionally, the birth weight, gestational age, the need for resuscitations, direct breast feeding and being beside mother were found to be significantly associated with the studied outcome.Conclusions: Majority of causes of neonatal morbidity and mortality in our study were preventable diseases. Therefore, interventions to improve services in the NICU are highly needed to improve the outcomes.

Background: Severe acute malnutrition (SAM) causes almost half of childhood deaths in children <5 years in developing countries. In India, as National Family Health Survey (NFHS), prevalence of SAM has increased from 6.4 in NFHS-3 (2005-2006) to 7.5% in NFHS-4 (2015-1016); [5.8 to 9.5% Gujarat]. The aim of study was to determine the etiological factors and outcome of SAM and the benefit of nutrition rehabilitation centre (NRC) among 6 months to 5 years children at the Pediatrics, NRC ward, Sir T. General Hospital.Methods: A prospective observational study of 151 SAM children over nine months. Etiological factors were determined by history and relevant investigations, exclude other systemic disorders. Therapeutic nutrition was provided for 14 days. Cases were followed up two weekly for 2 months by monitoring weight after NRC admission.Results: Association was found between Small for gestational age (64.9%), joint family (59.6%) and low birth spacing (59.6%) as etiological factors leading to SAM. 81.5% children gained weight during 14 days NRC stay. Weight gain was noted at follow-up. Defaulter rate increased from 9.9% at discharge to 28.5% at 2 months follow-up. Weight was static for 9% children. 34.4% children were from rural area and 65.6% from urban area. 23.8% children had received pre lacteal feed. Timing of complementary feeding was incorrect in 29%. There were no deaths.Conclusions: Small for gestational age, joint family, low birth spacing, and incorrect feeding practices and urban residence were etiological factors. NRC stay (defaulter rate 26%), produced weight gain in SAM children.

Background: The aim is to study neonatal thrombocytopenia and associated factors and compare the results with recent studies in neonates with thrombocytopenia admitted in neonatal intensive care unit (NICU).Methods: After taking detailed consent from parents/guardians, detailed maternal obstetrics and neonatal history were taken and complete physical examination was done and details of the investigations done and outcome was noted and evaluated. Relevant data was entered in the predesigned proforma and was analyzed. Immediate outcome was assessed by outcome or death.Results: The most common cause of neonatal thrombocytopenia was preterm gestational age. There were 68 (27.2%) neonates in the age group 28-32 weeks, 107 (42.8%) were in the age group 32-37 weeks and 75 (27.2%) were in the age group 37-42 weeks. Majority of the neonates were in the age group 32-37 weeks. We assessed outcome which was as follows, 98 (39.2%) neonates had expired and 152 (60.8%) neonates had survived in our study.Conclusions: We studied the etiology of neonatal thrombocytopenia and associated factors. The most common cause of neonatal thrombocytopenia found was preterm gestational age. The most common type of neonatal thrombocytopenia found in our study was moderate to severe thrombocytopenia. In our study, there was 39.6% was neonatal death rate. In our study, neonatal thrombocytopenia was associated with the following factors gestational age, intrauterine growth retardation, pre-eclampsia, multiple pregnancy, eclampsia, birth asphyxia, x-ray chest/abdomen, ultrasonography (USG) abdomen, USG cranium, liver function tests and renal function tests.

Published: March 2021

Background: Definitive diagnosis of pulmonary artery hypertension (PH) requires an elevated mean pulmonary arterial pressure (MPAP) of 25 mmHg at rest measured by right heart catheterization (RHC). As it is invasive mode of investigation, it is declined by many patients, echocardiography was thought to be an acceptable substitute to assess pulmonary arterial pressures. Whether there is a correlation between these measurements is controversial. The aim of this study was to assess PH by echocardiography and its correlation with RHC.Methods: Twenty-six patients aged ≥18 years with pulmonary artery hypertension with or without tricuspid regurgitation (TR) were included in this cross-sectional study. All the patients underwent a transthoracic echocardiography evaluation and were taken for RHC study within an hour.Results: The correlation between pulmonary artery acceleration time (PAAT) and pulmonary artery systolic pressure (PASP) and PAAT and MPAP was significant in all degrees of PH. In contrast, correlation between TR jet maximum velocity (TR Vmax) derived estimated pulmonary artery systolic pressure (EPASP) and PASP was significant in moderate and severe PH, while it did not correlate in mild PH.Conclusions: PAAT is easily measurable parameter and strongly correlates with the values of PASP and the MPAP obtained by right heart catheterization. Implementation of a novel method of determining EPASP from PAAT shall increase significantly the number of patients in whom TTE can be used for the assessment of pulmonary hemodynamic non-invasively.

Background: Hematological abnormalities are known to be independent predictors of morbidity and mortality in HIV-infected patients. The current study was conducted to evaluate the hemoglobin levels and CD4 count at the time of initiation of highly active antiretroviral therapy (HAART) of newly diagnosed HIV/AIDS patients attending ART centre at Goa Medical College.Methods: A hospital based observational retrospective study was carried out in Department of Medicine of Goa Medical College in collaboration with ART centre from October 2015 to January 2016. Patient’s relevant data about the infection was collected from patient’s treatment record card at the ART centre using preformed questionnaire.Results: The prevalence of anaemia in study participants was 66.35%. The prevalence of severe anaemia and mild-moderate anaemia was 9% and 57.3% respectively, while 33.65% of participants were not anaemic. Significant difference was observed in the prevalence of anaemia among immune deficient male participants (CD4 count <500 cells/mm3) and participants with no significant immune deficiency (CD4 count ≥500 cells /mm3) (77.5% versus 50%). Significant difference was also seen in the prevalence of anaemia among immune deficient female participants (CD4 count <500 cells/mm3) and participants with no significant immune deficiency (CD4 count ≥500 cells /mm3) (93.5% versus 56%).Conclusions: The current study revealed high prevalence of anemia in HIV patients prior to the initiation of ART in both males as well as females. Mild to moderate anemia was predominant in the study participants than severe anemia. There was significant difference observed in the prevalence of anemia among immune deficient population and participants with normal CD4 count. Prompt diagnosis of anaemia, identification of the underlying cause of anaemia in HIV patients as well as the implementation of appropriate treatment is essential.

Background: The aim of this study was to assess the prevalence and clinical predictors of silent myocardial ischemia in patients with type 2 diabetes mellitus, and the early diagnosis of coronary artery disease.Methods: A cross sectional prospective study was conducted including all confirmed diabetic patients in the age group between 40-60 in Bharati medical college hospital Pune in western Maharashtra. A detailed clinical examination and history was taken and relevant laboratory investigations, Electrocardiogram and Treadmill Stress test was done using Bruce protocol. The quantitative data was represented as their mean ± SD. Categorical and nominal data was expressed in percentage. All analysis was carried out by using SPSS software version 21.Results: Male preponderance was seen in the study with 64% of the study subjects. The mean age of the study subjects was 50.67±5.51 years. A p<0.001 was obtained showing positive correlation between BMI and TMT positivity. TMT positivity steadily increased with the duration of diabetes mellitus. Obtained p<0.001. The correlation between dyslipidemia and TMT positivity was significant, with a p=0.007. Correlation of Fasting as well as Post-prandial blood glucose levels with TMT positivity proved to be statistically significant, with a p<0.001.Conclusions: Exercise Treadmill test in diabetic patients has a significant role in screening diabetic individuals for coronary ischemia. The results obtained clearly indicate that an exercise treadmill test may be proposed as the first test for screening for coronary ischemia in diabetic population as it is safer, cheaper and non-invasive.

Background: It has been seen that epidemiology and clinical presentation of dengue infection differs significantly across geographical areas. The present study was done to study clinico-hematological profile of patients with dengue fever in Navi Mumbai, Maharashtra.Methods: This prospective observational study was conducted at a tertiary level teaching hospital in Navi Mumbai. All patients were observed over their entire duration of their hospital stay (up to 7 days). We included adult patients of both gender (males or females) who were admitted with clinically and serological diagnosed dengue fever, consenting to participate in the study.  The clinical, laboratory and radiological findings of the patients were noted.Results: All 80 patients presented with fever while 71.25% had myalgia. Retro-orbital pain, rash and vomiting was observed in 38%, 26% and 26% respectively, whereas 23.75% patients were having cough and bleeding from any site. Three fourths of the patients were diagnosed with dengue, 18.75% and 6.25% were diagnosed with DHF and DSS. respectively. Hepatosplenomegaly was increasing from day 1 (9%) to 6th (60%) and 7th (60%) day. Mean haemoglobin levels and haematocrit started increasing from second day onwards, while WBC count and platelet count increased gradually from first day onwards. Splenomegaly was diagnosed in 3.75% of patients while hepatosplenomegaly and fatty liver was observed in 8.75% and 2.5% respectively. There were two deaths, both were cases of DSS.Conclusions: Almost all the patients included in our study showed both haematological and biochemical abnormalities.
