Published: January 2022

В настоящей работе рассматривается теория микрополярной упругости Нейбера в псевдотензорной формулировке. Приводятся минимально необходимые для понимания статьи сведения из алгебры и анализа псевдотензоров. Уравнения динамики микрополярного континуума представлены (наряду с абсолютной тензорной формой) в терминах псевдотензоров (относительных тензоров). Проведено сравнение динамических уравнений микрополярной теории упругости в псевдотензорной форме с абсолютной тензорной формой, предложенной Нейбером. То же самое сопоставление выполнено и для определяющих уравнений. Устранены недочеты в уравнениях динамики Нейбера и приведена их окончательная псевдотензорная форма.

The paper deals with Neuber’s theory of micropolar elasticity in a pseudotensor formulation. The minimum notes and requisite equations from algebra and analysis of pseudotensors are given. The micropolar dynamic equations are presented in terms of pseudotensors (relative tensors). The pseudotensor form of dynamic equations is compared with the absolute tensor form of the Neuber dynamic equations. The refinements of Neuber’s dynamic equations are discussed.

Authors: ULUBAŞOĞLU Hasan , ŞAHİNÖZ Saime , ŞAHİNÖZ Turgut , ULUBAŞOĞLU Pınar
Published: January 2022

Aim: This study was planned to analyse the unwanted pregnancies and to determine the frequency and causes according to risk groups. Materials and Method: This is a cross-sectional study conducted on 409 married volunteer pregnant women who applied to the hospital for prenatal care. A questionnaire prepared by the researchers was used for data collection. Percentage, mean, and chi-square test were used to evaluate the data. Results: The rate of unwanted pregnancies was found to be 23.2%. The rate of unwanted pregnancy decreases with age. The unwanted pregnancy rate decreases as the education level of the woman increases and this ratio decreases to 18.5% among university graduates. Conclusion: In this study, the high rate of unwanted pregnancies was since most of them were not using a family planning method or using traditional family planning methods. It was found that the risk group with the highest unwanted pregnancy rate was among young women. Since the rate of withdrawal method was high especially in young women and this can lead to unwanted pregnancies, it is necessary to give couples premarital education.
Bir ilçedeki gebelerde TORCH seroprevalansının araştırılması
Authors: KILIÇ Fatih , ERSAK Burak , YALÇINKAYA Adem
Published: January 2022

Amaç: Bir ilçedeki gebelerde ilk trimesterde toksoplazma, rubella, CMV, sifiliz, HIV ve hepatit B&C seroprevalansının belirlenmesini ve gebelik takibinde bu enfeksiyonların taranmasının gerekli olup olmadığını tartışmayı amaçladık.

Gereçler ve Yöntem: Çalışmaya bir ilçedeki mevcut olan tek kadın hastalıkları ve doğum polikliniğine bir yıl içinde başvuran 259 gebe dahil edilmiştir. Gebelerden ilk trimesterde alınan venöz kanda; rubella IgM&IgG, toksoplazma IgM&IgG, CMV IgM&IgG, HBsAg, anti-HCV, anti-HIV ve sifiliz (VDRL-RPR) serolojileri değerlendirilmiştir.

Bulgular: Hastaların seroloji sonuçlarında rubella IgG 255 (%98.5), CMV IgG 254 (%98.1), toksoplazma IgG 58(%22.4) hastada pozitif olarak bulundu. Bir hastada toksoplazma IgM ve IgG pozitif saptandı. Rubella IgM, CMV IgM, anti-HCV ve anti-HIV hiçbir hastada pozitif saptanmadı. Hastaların 2’sinde (%0.8) HBsAg, başka 2 (%0.8) hastada da VDRL-RPR pozitif saptandı. İki hastada HBV DNA testi ile Hepatit B hastalığı, bir hastada TPHA testi ile sifiliz hastalığı doğrulandı.

Sonuç: Bölgemizde rubella enfeksiyonunun aşılama programı sayesinde, CMV enfeksiyonun da gebelik öncesi dönemde geçirilerek bağışıklıklarının yüksek olması gebelikte taranmalarının uygun olmadığını göstermektedir. Bölgemizdeki toksoplazma için tespit edilen yüksek seronegatiflik oranları gebelik takibinde ilk muayenede toksoplazma yönünden bağışıklık durumunun belirlenmesinin yararlı olacağını göstermektedir. Hepatit B için gerekli taramalar yapıldıktan sonra mümkünse prekonsepsiyonel dönemde aşılama önerilmelidir. Hepatit C, HIV ve sifiliz taramasının maliyeti ve bölgemizdeki düşük prevelansı göz önüne alındığında riskli grupların taranması daha uygun gözükmektedir. Ancak ülkemiz Sağlık Bakanlığı, Birleşmiş Milletlerin belirlediği hedefler doğrultusunda tüm gebelerin özellikle HIV ve sifiliz açısından taranmasını önermektedir.

Authors: Shu Shinan , Bian Yang , Zhao Lin , Rong Jian , Liu Xiaoming
Published: January 2022

Pedestrian Level of Service (PLOS) is influenced by the factors of traffic conditions, road facility conditions and environmental conditions. Pedestrian flow rate was the key factor influencing PLOS for the reason that pedestrians’ visual scopes of pavement and the influencing degree of each influencing factor on sidewalks was differed under different pedestrian flow rates. In order to evaluate PLOS more accurately, this paper classified pedestrian flow rates into 6 stages. Then, significant influencing factors of traffic conditions, road facility conditions and environmental conditions, which influenced pedestrians’ satisfaction, were extracted respectively under each pedestrian flow rate by Spearman rank correlation method. Finally, the evaluation method of PLOS with multi-factors based on classification of pedestrian flow rates was put forward. In addition, the models got training with fuzzy neural network method. The test showed that the accuracy of the comprehensive evaluation model of PLOS under different pedestrian flow rates based on fuzzy neural network reaches to 92%, which is much higher than the model accuracy of previous researches.

Published: January 2022

The Skvortsov Herbarium of the Tsitsin Main Botanical Garden, Russian Academy of Sciences (MHA) in the 1945-1980s dealt with vascular plants and only scattered occasional collections of bryophytes and lichens were accumulated there without special arrangement. Since the late 1980s, the bryophyte studies in the MHA Herbarium became permanent and several projects were started since then, including the currently conducted “Moss Flora of Russia”. There are many white spots on the map of bryophyte exploration of Russia, but one of the most conspicuous was Yakutia, the largest administrative unit of Russia, covering 3,081,000 km2. Yana-Indigirka Region, originally defined as a floristic region, includes Verkhoyansky Range and some smaller adjacent mountain areas. It is the largest amongst the bryofloristic regions in Russia, but exploration of its territory, which is difficult to access, remains far from complete.

Several expeditions of the Institute for Biological Problems of Cryolithozone, Siberian Branch of Russian Academy of Sciences, and the Main Botanical Garden, Russian Academy of Sciences in 2000-2018 yielded in many bryophyte specimens, partly published in a number of papers. This dataset comprehensively represents the diversity of mosses of the Region. It includes 7,738 records of moss specimens preserved in the MHA Herbarium.

Une commedia tradotta male : Molière sous la plume de Mezzetin (1693)
Authors: De Luca Emanuele
Published: January 2022

En 1693, Angelo Costantini, dit Mezzetin, envoie à Violante de Bavière, grande princesse de Toscane, sa traduction manuscrite du Misanthrope . C’est la deuxième traduction dans l’ordre chronologique d’une œuvre de Molière en italien et surtout la première et seule réalisée par un comédien. En analysant ce manuscrit méconnu et le processus de traduction, l’article illustre la première pénétration de l’œuvre de Molière en Italie qui échappe aux circuits littéraires et livresques. La traduction dévoile ses enjeux davantage théâtraux et comiques que philosophiques et poétiques et invite en aval à réinterroger l’élaboration même du Misanthrope .

Authors: Parganiha Vivek , Shukla Soorya Prakash , Sharma Lokesh Kumar
Published: January 2022

Cloud computing is a vast area which uses the resources cost-effectively. The performance aspects and security are the main issues in cloud computing. Besides, the selection of optimal features and high false alarm rate to maintain the highest accuracy of the testing are also the foremost challenges focused. To solve these issues and to increase the accuracy, an effective cloud IDS using Grasshopper optimization Algorithm (GOA) and Deep belief network (DBN) is proposed in this paper. GOA is used to choose the ideal features from the set of features. Finally, DBN is developed for classification according to their selected feasible features. The introduced IDS is simulated on the Python platform and the performance of the suggested model of deep learning is assessed based on statistical measures named as Precision, detection accuracy, f-measure and Recall. The NSL_KDD, and UNSW_NB15 are the two datasets used for the simulation, and the results showed that the proposed scheme achieved maximum classification accuracy and detection rate.

Published: January 2022

Patients suffering from diabetes have to bear several other disorders due to this. Diabetic Retinopathy is one such disorder which affects diabetic patients. This disorder affects the patient’s eye leading to permanent blindness if left untreated. Another disorder is exudates in which lipid residues leak out from damaged capillaries. It appears as yellow flecks. Hard exudates can lead to life threatening disorders. Detecting Hard exudates help the Ophthalmologist to diagnose the severity of the patient’s condition and in turn help in better medication. This paper presents a method to adjust the contrast of the image which in turn helps in detecting the hard exudates which can be used for further processing. In this work, initially Otsu algorithm is applied and then compared with Machine Learning techniques due to the disadvantage of Otsu.

Authors: Torres Kelly M. , Statti Aubrey , Morales Caroline A.
Published: January 2022

The enrollment of K-12 English language learners (ELLs) has grown substantially over the last several decades and is projected to continue to increase in American public schools. Consequently, educators need to understand how to best support ELLs’ simultaneous acquisition of the English language and grade-level content. The purpose of this study was to investigate how technology can be most effectively utilized to enhance English learning students’ reading gains. Specifically, this study examined ELLs’ assessment scores received across the academic year through online reading enrichment programs. The findings of this study revealed that kindergarteners and second graders’ reading assessment scores resulted in significant differences across time but not for teachers. As a result, educators need to be mindful in how they structure literacy activities across the entire academic year particularly in the last quarter of the academic year since findings from this study revealed that students’ scores decreased during the last nine weeks of school.

Published: January 2022

Information and telecommunication technologies, together with the Internet, are completely changing the ways securities brokerages provide their products and services to customers. This study, conducted in a newly emerging country, looks at relationships among three major issues impacting brokerages’ Internet commerce: perceived value, customer satisfaction, and customer loyalty. It also examines whether the strength of these relationships is moderated by factors constituting customers’ technology readiness - optimism, innovativeness, discomfort, and insecurity. Results reaffirm prior research that perceived value is positively related to customer satisfaction and customer loyalty; and customer satisfaction is positively related to customer loyalty. Technology readiness factors were not shown to moderate the strength of the relationships among perceived value, customer satisfaction, and customer loyalty.

Published: January 2022

Universities typically offer support services to students in the form of technology assistance, academic tutoring, and mentoring programs. This mixed methods study explored supports provided to undergraduate students enrolled in online education courses at a four-year Hispanic Serving Institution (HSI) in Southern California. This study looked at the degrees to which undergraduate students enrolled in online courses took advantage of these services, their perceptions of the impact of such participation, and recommendations for additional support services specific to the online environment. The majority of students surveyed reported not utilizing many of the support services offered by the university. Recommendations include expanding support services to increase accessibility and connecting supports more clearly to course content.
Social Networks in the Learning Community
Authors: Chang Bo
Published: January 2022

The purpose of this study is to explore how social networks impact learners’ knowledge sharing in the context of a learning community. The findings indicate that the various networks collaboratively support learners’ knowledge sharing in a local community. A better social position gives rise to more networks and correspondingly more knowledge accessible to learners. The between-group ties such as residential committees are crucial for knowledge exchange through connecting various social networks. Social isolation impacts learners’ interactions with others. However, more networks do not necessarily lead to more advanced knowledge acquisition. Accessing social networks cannot guarantee that learners will successfully access substantial knowledge in other fields. Social networks targeting learners’ need influence learners’ interest in social networks.
Experimental Study of the Hydraulic Jump Compactness in an Open Trapezoidal Channel
Authors: Benmalek Ahmed , Debabeche Mahmoud , Zaid Zaid
Published: January 2022

In stilling basins there is a change in flow regime from supercritical to subcritical flow; this transition is called a hydraulic jump. To control and stabilize the position of the jump, it is necessary to place a sill across the flow. A bibliographical analysis showed that when the controlled hydraulic jump is entirely formed upstream of the stilling basin, the sill has no effect on the configuration of the jump. However, when the jump length stretches beyond the sill position, this results in jump compactness and leads to several configurations of the latter, until it completely disappears. The main objective of this study is to determine the effect of the hydraulic jump compactness on the main jump features in a trapezoidal horizontal channel. Dimensionless empirical relationships depending on the jump compactness are obtained. Through this study, we aim to show the advantages of the jump compactness on the channel dimension. Indeed, the hydraulic jump is led to its most reduced form, before disappearing, in terms of tail water depth and jump length. Thus, the obtained results are useful for dimensioning the stilling basin.
Is Indexed Left Atrial Volume (LAVi) in Indian Patients with Acute Coronary Syndrome (ACS) Undergoing Revascularization a Predictor of Cardiovascular Outcomes?
Authors: Saklecha Abhishek , Kapoor Aditya , Sahu Ankit , Khanna Roopali , Kumar Sudeep , Garg Naveen , Tewari Satyendra , Goel Pravin
Published: January 2022

Background:

Left atrial volume indexed to body surface area (LAVi) is the recommended method for LA size quantification. Assessing LAVi in Indian patients undergoing coronary interventions for acute coronary syndrome (STEMI, NSTEMI, and UA) is clinically relevant.

Methods and Results:

Amongst 190 patients (66.4 yrs, 68.4% males), 29.5%, 40.5%, and 30% respectively had STEMI, NSTEMI and UA. Mean LAVi was 32.29 ± 12.06 ml/m2 and 111 (58.4%) had LAVi ≥32 while 79 (41.6%) had LAVi <32. Patients were divided into 2 groups (group 1 LAVi >32 and group 2 LAVi <32). Group 1 patients had higher prevalence of TVD [n = 49 vs n = 5, p = <0.001] and higher mean Syntax score (24.47 vs 14.64, p = <0.001). Despite similar LVEF, those with higher LAVi had had higher incidence of mild MR (50.4 vs 27.8, P = 0.0002) and moderate/severe MR was present only in Group 1 patients (27.9% and 5.4%). Grade I, II, and III diastolic dysfunction was present in 71.2, 17.1, and 9.9% patients in Group 1 vs 45.6%, 0%, and 0% in group 2. Diastolic parameters like septal E/e' and lateral E/e'ratio were also higher in Group 1. Major adverse cardiovascular events (MACE) at 30 days was significantly higher in group 1 (20.7 vs 6.3%, P = 0.006). On multivariate analysis, triple vessel disease and LAVi were the only predictors of MACE while LVEF was not. ROC curve analysis for LAVi demonstrated that a cut-off 33.35 ml/m2, predicted 30 day MACE with Area under curve (AUC) 0.775 (95% CI 0.700-0.850); sensitivity and specificity of 86.7% and 61.4%. Inter-quartile analysis of LAVi (<26.3, 26.3-33.35, 33.36-36.3, and >36.3 ml/m2) demonstrated that 30 day MACE increased across quartiles (4.16%, 4.25%, 22.44%, and 28.26%, respectively, P < 0.001).

Conclusion:

Amongst patients with ACS undergoing revascularization, those with higher LAVi had more severe CAD, diastolic dysfunction and higher 30 day MACE. LAVi provides superior prognostic information as compared to conventional LV systolic and diastolic parameters in patients with ACS and should be incorporated in routine echocardiographic analysis. More studies with larger numbers and longer follow up are required to further elucidate on this.
Left atrial appendage (LAA) flow profile of its different waves and its correlation with direct left atrial pressure measurement
Authors: Tewari Prabhat , Mammen Anand , Pandey Shantanu , Ahmad Syed Shabbir , Hajela Kushal
Published: January 2022

Background:

Left Atril Appendage(LAA) is one of the most contractile structure of the heart. Elevated Left atrial pressure (LAP) can change the flow profile in and out of LAA. There is little data on the effect of LAP on LAA flow velocities for patients in sinus rhythm, and it's not properly known that by evaluation of LAA flow spectra and its velocities, the LAP can be predicted. We tried to find the relationship between LAA flow velocities and LAP, with the premise that LAA flow velocities can be used as a surrogate for measuring LAP, by obtaining a regression equation in this prospective observational study.

Methods:

In forty patients with normal systolic and diastolic heart function undergoing elective off pump coronary artery bypass (OPCAB) under general anaesthesia, TEE based LAA flow velocities were measured and simultaneous direct measurements of LAP was done by the surgeon. We also studied the relation between the ratio of early mitral inflow velocity (E) and mitral lateral annular early diastolic velocity (E'), that is, (E/E') in all patients.

Results:

We found significant correlation between E/E' and LAP (r = 0.424, p = 0.024) however there was no significant correlation between LAA flow velocities and LAP.

Conclusion:

LAA flow profile can not be used under anaesthesia to evaluate LAP however E/E' shows a strong correlation with directly measured LAP.
Euvolemic off Pump Coronary Surgery Further Improves Early Postoperative Outcomes
Authors: Rathore Kaushalendra , Boon Evan , Yussouf Reza , Newman Mark , Weightman William
Published: January 2022

Background:

Fluid resuscitation during Off-Pump Coronary Surgery (OPCABG) is still not protocolized and depends on multiple variables. We are exploring in this study whether a restrictive or euvolemic approach has any impact on short term surgical outcomes following OPCABG.

Methods:

It is a retrospective study of 300 patients analyzed based on the intraoperative fluid requirement with 150 patients in each group (Group I: Fluid <2 Litres, Group II: Fluid >2 Litres).

Results:

Multivariable analysis showed echocardiography variables such as E/e ratio, LA volume index, and atrial fibrillation (AF). LA volume index is related to the higher fluid requirement. Group II had significantly higher ventilation time (P < 0.05), drain output (P = 0.05), drain removal time (<0.05), inotropic requirement, and diuretic use.

Conclusion:

The requirement of the intraoperative fluid was associated with various factors including diastolic dysfunction (left atrial volume index, left ventricle mass index, E/e ratio) and preoperative dual antiplatelet use. Group II patients had longer ventilation time, diuretics use, high drain output, and required drains for a longer period of time. Although there was no statistical difference among two groups as far as postoperative AF concerned, a reversal of AF to sinus rhythm was delayed in group II patients.

Authors: Munirathinam Ganesh K , Kumar Bhupesh , Singh Harkant
Published: January 2022

After surgical excision of myxoma recurrence usually happens adjacent to the initial origin site. We report a case of recurrent myxomas in a young male patient that had biatrial recurrence with one tumor originating very unusually from the base of the anterior mitral leaflet. Intraoperative transesophageal echocardiography was instrumental in localizing the site of the origin of left atrial myxoma from the base of the anterior mitral leaflet and in detecting an additional myxoma attached to the wall of the right atrium.

Authors: Wang Yu , Xiang Ming-Fei , Zheng Na , Cao Yun-Xia , Zhu Fu-Xi
Published: January 2022

Acephalic spermatozoa syndrome (ASS) is one of the most severe spermatogenic failures of all infertility in men. The cognition of ASS has experienced a tortuous process. Over the past years, with the in-depth understanding of spermatogenesis and the emergence of new genetic research technologies, the unraveling of the genetic causes of spermatogenic failure has become highly active. From these advances, we established a genetic background and made significant progress in the discovery of the genetic causes of ASS. It is important to identify pathogenic genes and mutations in ASS to determine the biological reasons for the occurrence of the disease as well as provide genetic diagnosis and treatment strategies for patients with this syndrome. In this review, we enumerate various technological developments, which have made a positive contribution to the discovery of candidate genes for ASS from the past to the present. Simultaneously, we summarize the known genetic etiology of this phenotype and the clinical outcomes of treatments in the present. Furthermore, we propose perspectives for further study and application of genetic diagnosis and assisted reproductive treatment in the future.

Authors: Hajong Ranendra
Published: January 2022

Introduction:

Peristomal skin excoriation is the most common complication of any stoma, especially of ileostomy and entero-cutaneous fistula. Effluent is erosive to skin and at times leads to excoriation of skin and pain or discomfort to the patient. Many strategies or local medications are being used to treat excoriated skin and give comfort to the patient. Aluminium paint is a cheap and effective means of managing skin excoriation.

Materials and Methods:

This case-control study was conducted in NEIGRIHMS from January 2015 to October 2020 on the role of aluminium paint for the management of skin excoriations due to stoma and fistula. A total of 19 patients were managed with aluminium paint and compared with the data of 19 other patients who were managed by conventional dressings as controls.

Results:

Aluminium paint helped in the earlier healing of skin excoriations and give comfort to the patients as compared to normal dressings.

Conclusion:

Aluminium paint is safe and cost-effective skin barrier to prevent and to manage skin excoriations.

Authors: Kwak Han Deok , Chung Jun Seong , Ju Jae Kyun
Published: January 2022

Purpose:

Rectal prolapse is known to be a rare condition in males compared to females. This study aimed to analyse the frequency of male rectal prolapse and compare the results of different surgical approaches performed at a single centre.

Patients and Methods:

The authors included patients who underwent surgical treatment for rectal prolapse from March 2016 to February 2021. The proportion of males, mean age and recurrence rates were calculated. Patients were divided into two groups, transanal approach and laparoscopic abdominal approach group, to identify the para-operative parameters including functional tests.

Results:

A total of 56 males, comprising 23.7% (56/236) of all patients. The mean age was 60.8 years, with a recurrence rate of 7 cases (12.5%) during 7.2 months of follow-up. Forty patients underwent transanal procedures, and fifteen underwent laparoscopic abdominal procedures. The mean operative time was longer in the laparoscopic group (transanal vs. abdominal, 57.5 vs. 70.6 min, P < 0.003), and intra-operative bleeding was greater in the transanal group (12.4 vs. 3.4 ml, P < 0.001). Full-layer prolapse (36.8 vs. 81.2% P = 0.003) and longer length (5.6 vs. 7.8 cm, P = 0.048) were more common in laparoscopic group. Time to feeding resumption was shorter after the transanal group (1.2 vs. 1.7 days, P = 0.028). There was no difference between the groups in terms of post-operative complications and recurrence rates. Both Wexner's constipation and incontinence scores showed significant improvement postoperatively.

Conclusion:

The frequency of male rectal prolapse was 23.7%, and perioperative factors differed between transanal and abdominal approaches, but recurrence rates and functional test results did not differ significantly.

Authors: Ahmad Aijaz , Chakraborty Rashmi , Goyal Sunil , Kapoor Amul , Sidhharth Sonia , Ahmad Parvaiz
Published: January 2022

Introduction:

Novel coronavirus disease-2019 pandemic continues to rage the world with enormous economic loss, sickness, and deaths. In management of infectious diseases, nurses play crucial roles in rendering care to patients by risking their own lives, going beyond their training and capacities. Frontline nurses are vulnerable for the development of diagnosable and subclinical psychological problems most often triggered with deaths of colleagues, exposure to the mass scale of deaths, perceived inability to save lives despite best efforts, lack of social supports, shift duties, and working in high-risk environment.

Aim:

The aim of the study is to assess the depression, anxiety, and stress among nurses working in COVID wards versus non-COVID wards.

Materials and Methods:

A multicenter observational study was done among 176 frontline nurses from seven different referral government hospitals. Psychological ailments were measured on validated instruments of Depression, Anxiety, and Stress Scale-42 items (DASS-42) and Perceived Stress Scale-10 (PSS-10).

Results:

Using SPSS version 23.0, data were analyzed using Pearson's Chi-square test, with P < 0.055 being considered statistically significant. On PSS, perceived stress was high in 75% of COVID ward nurses and 67% of non-COVID ward ones. On DASS-42 scale, depression, anxiety, and stress levels among nurses in the COVID-19 wards were 21.64% (n = 21), 32.98% (n = 32), and 20.61% (n = 20) compared to 17.72% (n = 14), 24.05% (n = 19), and 15.18%, (n = 12) in the non-COVID wards, respectively.

Conclusions:

The amount of reported stress, anxiety, and depression was higher in both groups of nurses, i.e., those working in COVID-19 wards and general wards as compared to general population.

Authors: Ghosh Joydeep , Das Amit Kumar , Janney Manasa Shettisara
Published: January 2022

Introduction:

Emergence of a novel coronavirus disease (COVID 19) and its subsequent spread to India lead to declaration of lockdown by the government in various phases to reduce the transmission of COVID 19. Northeastern India being relatively remote had its first case relatively late. Later, with incoming migrant population, there was a surge in cases. This study aims to determine the clinicoepidemiological characteristics and outcomes in COVID 19 positive migrant population treated at multiple centers in Northeast India.

Methods:

This is a retrospective, cross-sectional, multicentric study. Data were collected from case sheets of 198 COVID-19 positive patients treated at designated COVID-19 hospitals in Northeast India.

Results:

Independent t-test and Fisher's exact test were used. P<0.05 was considered statistically significant. Majority of the study population were between 31 and 50 years (62.1%) with overall male preponderance (94.9%). Nearly one third (31.8%) of the study population gave a history of contact. Fever was seen 92.4% of patients. Majority (97.0%) of the study population had mild to moderate disease and only 3.0% were severely diseased/critically ill. 30%, 7%, and 3% of the study population received oxygen support, noninvasive ventilation, and ventilator support, respectively. Only 1.5% of the study population had complications of acute respiratory distress syndrome, shock, and sepsis, and the mortality rate was 1.1%. The average duration of hospitalization was 14.17 ± 5.48 days, and the average time taken to become COVID negative by reverse transcription polymerase chain reaction was 37.93 ± 7.54 days.

Conclusion:

A large number of COVID-positive patients had mild-to-moderate course of disease. Fever was the most common symptom. Around one-third of patients required respiratory support. Rate of complications and mortality were low in the study population. Presence of comorbidities, “O” blood group, abnormal X ray findings, elevated levels of C reactive protein, D dimer, and erythrocyte sedimentation rate had a significant positive association with severity.
Diagnostic Dilemmas in Cutaneous Pseudolymphomas

Published: January 2022

Cutaneous pseudolymphoma (CPL) is an umbrella term encompassing reactive lymphoproliferation that imitates cutaneous lymphomas clinically and/or histopathologically. We present the case of an elderly male presenting with solitary, painless, raised, and progressive swelling on the right side of the face of 9-month duration. Examination revealed a solitary, raised, slightly erythematous nodule without any surface changes. Clinically, the neoplastic differentials were given precedence owing to rapid onset and age at presentation. The nodule was excised in toto and, following histopathological examination and immunohistochemistry (IHC), diagnosed as CPL. We elaborate how pseudolymphomas can mimic lymphoma and can be distinguished only with an integrated clinical, histomorphological approach and the use of ancillary techniques including IHC.

Published: January 2022

BACKGROUND:

With the increasing number of COVID positive cases still being reported in the country, coupled with the possible vulnerability of pregnant patients to the disease, aggressive measures must be taken by all institutions to ensure safety of the patients.

OBJECTIVE:

This study aimed to the determine the clinical profile and pregnancy outcome of patients who were admitted at a tertiary private hospital in Metro Manila from March 16, 2020 to June 15, 2020 in relation to the protocols that were implemented in response coronavirus disease 2019 pandemic.

METHODS:

The protocols and guidelines implemented by the Department of Obstetrics and Gynecology of a private tertiary hospital in Metro Manila from March 16, 2020 to June 15, 2020 were retrieved. The case record of patients who were admitted and delivered during this period were retrieved and reviewed for pertinent data, which were recorded in a patient data collection form.

RESULTS:

During the 3-month study period, COVID positive pregnant patients were effectively separated from COVID negative patients from admission to discharge based on a health declaration form and universal reverse transcriptase polymerized chain reaction (RT-PCR) testing. Discharge was facilitated after 12–48 h for uncomplicated deliveries and post partum follow-up was done via telemedicine.

CONCLUSION:

The separation of COVID positive from COVID negative patients based on symptoms and RT-PCR results were effective in ensuring the safety of patients.

Patients cannot wear ocular prostheses after undergoing orbital exenteration. They require a facial prosthesis to obtain a more favorable appearance, which greatly affects their social life and psychological health. In addition, conventional prosthesis-making processes require substantial time and expense. The economic burden is particularly heavy on children, who may require many prosthesis replacements as they mature. We report a method of fabricating a facial prosthesis by three-dimensional (3D) facial scanning and 3D printed for a 13-year-old girl who underwent partial orbital exenteration for malignant ciliary body medulloepithelioma 2 years ago. The patient's facial contour was captured with a hand-held, point-and-shoot 3D scanner. A facial prosthesis was designed using a mirror image technique with 3D modeling software and 3D printed. The prosthesis was then postprocessed and cast in silicone rubber. An ocular prosthesis was integrated into the facial prosthesis. The prosthesis was retained by prosthetic adhesives. This digitally assisted, impression-free method may lower the cost and effort of making facial prostheses and improve patient comfort, especially for children.
Colorectal adenocarcinoma with enteroblastic differentiation: diagnostic challenges of a rare case encountered in clinical practice

Published: January 2022

Colorectal adenocarcinoma with enteroblastic differentiation (CAED) is a rare subtype of colonic adenocarcinoma characterized by increased α-fetoprotein (AFP) production and the expression of at least one enteroblastic marker including AFP, glypican 3 (GPC3), or Spalt like transcription factor 4 (SALL4). We report a case of a 26-year-old female who presented with low back pain and constipation which persisted despite supportive measures. Imaging revealed multiple liver lesions and enlarged retroperitoneal nodes. Tumor markers including AFP were markedly elevated. On biopsy, samples from the liver revealed infiltrating glands lined by columnar-type epithelium with mostly eosinophilic granular to focally clear cytoplasm. By immunohistochemistry, the tumor showed immunoreactivity with AFP, hepatocyte antigen, GPC3, SALL4, CDX2, SATB2, and cytokeratin 20. A colonoscopy performed subsequently revealed a mass in the sigmoid colon and biopsy of this mass revealed a similar histology as that seen in the liver. A diagnosis of CAED was made, following the results of gene expression profiling by the tumor with next-generation sequencing which identified pathogenic variants in MUTYH, TP53, and KDM6A genes and therefore supported its colonic origin. Cases such as this underscores the use of ancillary diagnostic techniques in arriving at the correct diagnosis in lesions with overlapping clinicopathologic characteristics.

Published: January 2022

Solitary fibrous tumor (SFT) is a rare type of mesenchymal neoplasm that first was discovered in the pleura but can also affect the peritoneum, lungs, mediastinum, and skin. Cutaneous malignant SFT is an extremely rare tumor that resembles dermatofibrosacoma protuberance (DFSP) histologically and immunohistochemically. Herein, we describe a case of malignant SFT that presented as a recurrent mass on the scalp. The first lesion was totally excised one year before recurrence and was diagnosed as a DFSP based on the histopathology and cluster of differentiation 34 immunostaining positivity. Re-examination of the previously examined specimen was considered. Activator of transcription 6 positivity was also detected in the tissue, confirming the diagnosis of a recurrent malignant SFT rather than DFSP. There was no evidence of recurrence, locoregional, or distant metastases at six months after lesion removal with a safety margin.

Vücudun fizyolojik ve biyolojik işlevlerinin merkezi olan endokrin sistemin, işlevini bozan ve organizmada ya da bu organizmanın gelecek kuşaklarında olumsuz etkilere neden olan endokrin bozucu maddeler ile ilgili çalışmalar son yıllarda oldukça merak konusu haline gelmiştir. Hayvan modelleri ve insanlar üzerine yapılan araştırmalar, endokrin bozucuların etki ettiği mekanizmaların farklı yollar içerdiğini ortaya koymaktadır. Endokrin bozucular; pestisitler, metaller, plastik şişeler, gıda ambalajları, deterjanlar, kozmetik ürünleri ve günlük hayatta kullanılan birçok materyalin içeriğinde doğal veya sentetik olarak yer almaktadır. Endojen hormonların fonksiyonunu taklit eden, hücresel aktiviteyi manipüle ederek hormon üretimini attıran, azaltan veya bloke edebilen bu maddelerin sinir sistemi, nörodavranış, bağışıklık ve metabolik aktivite gibi birçok temel biyolojik fonksiyona etki ettiğine dair literatürde birçok kanıt bulunmaktadır. Bunun yanı sıra endokrin bozucuların infertilite, hamilelik, fetal gelişim ve kadın üreme sağlığı üzerinde de olumsuz etkilere sahip olduğu bildirilmiştir. Bu çalışmada yaygın olarak üreme ve gelişim toksisitesi ile ilişkilendirilen bisfenol-A (BPA), poliklorlu bifeniller (PCB), dietilstilbestrol (DES), pestisitlerin bir türevi olan diklorodifeniltrikloroetan (DDT), fitalatlar, metaller, etanol ve talidomid gibi endokrin bozucuların etkilerinin ve etki mekanizmalarının gözden geçirilmesi amaçlanmış ve bu maddelere maruziyetin uzun vadede kuşaklar arasında bile bir toksik hasar oluşturma potansiyeline sahip olduğu saptanmıştır.

The aim of this study was to estimate the effect of personalized metabolic support on the character of dehydration structuring of blood serum of qualified athletes. The study included 55 athletes with the category of cyclical sports. The random number test subjects were divided into 2 groups: the main group (n=23), where individualized metabolic correction was performed, and the comparison group (n=22), whose received placebo. Blood samples were obtained from athletes of both groups before the course and immediately after its completion. Then micro-preparations were prepared using the technology of classical crystalloscopy. Crystalloscopic facias were estimated with own system of visuamitric parameters. The study allowed us to establish that in qualified athletes, the course of taking biologically active agents, individualized on the basis of a multiparametric assessment of the state of oxidative metabolism of blood, contributed to the optimization of the crystallogenic properties of blood serum. This was manifested in the transformation of the structure of the main elements of the picture in the direction of reducing their size with a proportional increase in density, as well as in reducing the degree of destruction of crystals and expanding the marginal zone of the micropreparation.
