No início do ano de 2020, cerca de 9 milhões de habitantes da Região Metropolitana do Rio de Janeiro dependente do Sistema Guandu, vivenciou uma crise no abastecimento de água, recebendo água com gosto e odor. Este trabalho realizou a análise da qualidade sanitária da água bruta, captada por esse sistema, em dois momentos distintos, “na crise” e “pós-crise”, quanto à presença de cianobactérias e cianotoxinas na água bruta, através de estudos de metagenômica e de quantificação de cianotoxinas, microcistina (MC) e saxitoxina (SXT) por ELISA, comparando métodos de extração e processamento. Foram também realizadas análises de parâmetros de qualidade da água bruta, através da determinação dos níveis de coliformes totais e de Escherichia coli e de alguns parâmetros físico-químicos, de modo a se comparar com dados de análises do INEA. A água bruta captada nos dois momentos estava com níveis de Escherichia coli, acima da faixa de valores máximo permitidos (VMP) descrito na Resolução n. 357/2000 do CONAMA, enquanto os parâmetros físico-quimicos analisados apresentaram níveis satisfatórios, assim como os níveis das cianotoxinas, para SXT. Entretanto, destaque-se que na metodologia de extração por filtro, a amostra “pós-crise¨ não estava dentro do VMP para a cianotoxina MC. Portanto, caso a análise tivesse sido feita por esta mesma metodologia, é provável que os valores de MC das amostras no momento da crise também estariam acima do VMP. Isto porque, na metodologia comumente usada, o valor para MC foi acima do VMP para o momento ¨pós-crise¨. Portanto, na revisão da Portaria de Potabilidade se faz necessário descrever uma metodologia de extração que possa expressar o real risco em relação aos níveis de cianotoxinas presentes na água bruta. Desta forma, é importante que seja implementado, o quanto antes, o saneamento nas cidades a montante da captação de água bruta desse manancial, a fim de que eventos como os acontecidos durante a “crise hídrica” não seja vivenciado novamente. Além disso, a curto prazo, é necessária a realização de monitoramento periódico dos reservatórios, integrando as análises de genômica, biogeoquímica e de toxicidade, para que estação de tratamento tome as decisões adequadas para evitar algum problema e garantir a qualidade do abastecimento. Outrossim, esse recomendado procedimento poderá fornecer dados para a realização do Plano de Contingência, para que o quadro de floração não se amplie.
Sliding-Window Thompson Sampling for Non-Stationary Settings
Authors: Trovo Francesco , Paladino Stefano , Restelli Marcello , Gatti Nicola
Published: May 2020

Multi-Armed Bandit (MAB) techniques have been successfully applied to many classes of sequential decision problems in the past decades. However, non-stationary settings -- very common in real-world applications -- received little attention so far, and theoretical guarantees on the regret are known only for some frequentist algorithms. In this paper, we propose an algorithm, namely Sliding-Window Thompson Sampling (SW-TS), for nonstationary stochastic MAB settings. Our algorithm is based on Thompson Sampling and exploits a sliding-window approach to tackle, in a unified fashion, two different forms of non-stationarity studied separately so far: abruptly changing and smoothly changing. In the former, the reward distributions are constant during sequences of rounds, and their change may be arbitrary and happen at unknown rounds, while, in the latter, the reward distributions smoothly evolve over rounds according to unknown dynamics. Under mild assumptions, we provide regret upper bounds on the dynamic pseudo-regret of SW-TS for the abruptly changing environment, for the smoothly changing one, and for the setting in which both the non-stationarity forms are present. Furthermore, we empirically show that SW-TS dramatically outperforms state-of-the-art algorithms even when the forms of non-stationarity are taken separately, as previously studied in the literature.
A Phase II Prospective, Randomized, Double-Blind, Placebo-Controlled and Multicenter Clinical Trial to Assess the Safety of 0.005% Estriol Vaginal Gel in Hormone Receptor-Positive Postmenopausal Women with Early Stage Breast Cancer in Treatment with Aromatase Inhibitor in the Adjuvant Setting

Published: May 2020

Lessons Learned

The levels of circulating follicle-stimulating hormone, luteinizing hormone, estriol, estradiol, and estrone remained unchanged after a 12-week treatment with 0.005% estriol vaginal gel in postmenopausal women receiving nonsteroidal aromatase inhibitors for hormone receptor-positive early breast cancer. These results support the safety of 0.005% estriol vaginal gel for the treatment of bothering symptoms of vulvovaginal atrophy in breast cancer survivors. The results provide clinicians with confidence in the use of this product in women who do not experience symptom relief with nonhormonal remedies.

Background

Symptoms of vulvovaginal atrophy associated with treatment with nonsteroidal aromatase inhibitors (NSAIs) negatively impact patients’ quality of life and may affect adherence to NSAIs. Vaginal estrogens effectively improve these symptoms, although their safe use in breast cancer survivors remains unclear.

Methods

Postmenopausal women with hormone receptor-positive early breast cancer receiving NSAI and moderate-to-severe vaginal dryness were randomized to 0.005% estriol vaginal gel or placebo for 12 weeks. Circulating estrogens, follicle-stimulating hormone (FSH), and luteinizing hormone (LH), were analyzed at baseline and at weeks 1, 3, 8, and 12. The primary safety outcome was the variation in serum FSH from baseline to week 12.

Results

Sixty-one women (mean age, 59 years) enrolled in the study. Small oscillations were observed in FSH and LH, although they were always maintained within the postmenopausal range. No significant differences were found in the variation of FSH and LH between baseline and week 12 from the physiological variation observed before treatment. Women receiving 0.005% estriol vaginal gel had slightly increased estriol levels at weeks 1 and 3, with a subsequent reduction until normalizing at week 12; estradiol and estrone remained the below limit-of-quantitation in almost all samples.

Conclusion

Ultralow-dose 0.005% estriol vaginal gel did not significantly influence estrogens, FSH, and LH levels in women with breast cancer receiving NSAI. A transient negligible absorption of estriol and a nonsignificant variation of FSH after 12 weeks were observed. These findings provide confidence for the safe use of 0.005% estriol vaginal gel in women with breast cancer with an indication for treatment with vaginal estrogens.
Prevalence of Oral and Para-Oral Lymphomas in Educational Hospitals and Institutions in Cairo Governorate: A Retrospective Study v1
Authors: Ashoub Madiha
Published: May 2020

Lymphoma is a malignant group of neoplasms with a wide range of behavioral spectrum ranging from relatively indolent to highly aggressive (Silva et al., 2016). Lymphoma is classified into two main groups, Hodgkin’s Lymphoma and Non-Hodgkin’s Lymphoma. Not only is Non-Hodgkin’s Lymphoma more common, but it also includes a variety of histological subtypes with different behaviors that require different treatments (Neville et al., 2016). While Hodgkin’s Lymphoma occurs mainly in lymph nodes and rarely shows extranodal disease (only 1%) (Sirsath et al., 2014), Non-Hodgkin’s Lymphoma can occur in extranodal sites in almost 40% of cases (Neville et al., 2016). The head and neck region is the second most common extranodal site for Non-Hodgkin’s Lymphoma, mainly affecting tissues of the Waldeyer ring, salivary glands and the oral cavity (Triantafillidou et al., 2012). Despite the rare occurrence of Lymphoma in the oral and para-oral regions, it is very important for clinicians, oral surgeons and pathologists to be aware of its clinico-pathological features as well as the distribution of its various subtypes among different populations (Storck et al., 2019). This is because oral Lymphoma may clinically and radiographically resemble other oral lesions such as odontogenic infections or other oral malignancies (Walter et al., 2015). Thus, lack of awareness of pattern of involvement of Lymphoma can often lead to low index of clinical suspicion which may lead to misdiagnosis, improper treatment and worse prognosis (Sirsath et al., 2014; Kusuke, Custódio and de Sousa, 2019). Hence, the aim of this study is to assess the prevalence and types of oral and para-oral Lymphomas in educational hospitals and institutions in Cairo. Besides, efforts will be made to correlate the results of the current study with those of previously published studies in other populations.
Studies on the Backward Transfer of Interlanguage Syntactic Structure—Taking Temporal Adverbial Clause as an Example
Authors: Yuan Chen
Published: May 2020

The research focuses on the language transfer in L2 and L1 environment. The paper explores the language backward transfer from L2 (English) to L1 (Chinese) for mainland Chinese students in Australia as well as in China. With long time scholars concentrated on the forward transfer from L1 to L2 and profited a lot. However, there is some evidence reflected that backward transfer from L2 to L1 may take place in L2 and L1 environment, even in some academic occasion, L1 syntactic rules are losing. In this study, participants are mainland Chinese undergraduates from University of Newcastle and Hei Longjiang Bayi Agricultural University to complete translation and writing tasks. The aim of the paper is to investigate whether the backward transfer occurs in sentence translation and discourse level and the relationship between the backward transfer and L2 proficiency. The expected results are that backward transfer can happen both in L2 and L1 environment and the higher L2 proficiency can decrease backward transfer. In view of this, the research can reflect the complexity of language backward transfer and the relationship with L2 proficiency.
Historical analysis of the hypotheses of tectonic morphogenesis of the Male Polissia Basin
Authors: Mysak M.
Published: May 2020

The hypotheses of morphogenesis of the Male Polissia Basin, where the influence of the tectonic factor is considered, are analyzed in this article. The analysis was carried out on the basis of existing literary and cartographic sources related to geological and geomorphological studies of Male Polissia. Two groups of tectonic hypotheses of morphogenesis of Male Polissia are defined: denudation-tectonic and tectonic-denudation. Suppoters of the denudation-tectonic hypothesis claimed that the main factor in the morphogenesis of the Male Polissia was denudation, and tectonic processes only contributed to increasing its intensity. The representatives of this hypothesis were E. Titze, J. Novak, A. Zierhoffer and J. Czyżewski,H. Zilber, P. Tsis` and I. Chervanov. Most of them, believed that the reason for intense denudation were block tectonic elevations. Their views differed in main intensity and localization of elevations within the Male Polissya and adjacent territories of the Podolian and Volyn’ Uplands, and also Roztochia. Supporters of tectonic-denudation hypotheses considered tectonics as a decisive factor in the morphogenesis of the Male Polissia Basin. In their hypotheses, the main tectonic processes were linear tectonic elevations along the Podolian escarpment, or block tectonic subsidence of the Male Polissia Basin, which, mainly, formed the modern limits of it. Supporters of the tectonic-denudation hypothesis were W. Teisseyre, W. Lozinski, J. Siemiradzki, J. Smolenski, T. Wiśniowski, S. Rudnytskyi, H. Teisseyre, K. Gerenchuk, I. Hofshtein and Y. Swynko. The comparative table of the ideas of researchers regarding the localization and age of tectonic processes, that influenced the genesis of the Male Polissia Basin, is also presented in the work. The existing scientific data on the neotectonic movements of the research area is also analyzed. Data on the intensity, localization and direction of these movements are distinctive. Also, a historical analysis of ideas concerning the tectonic origin of the Hriadove Pobuzhia Upland and the research of stratigraphy of Cretaceous deposits along the border of Male Polissia and Podolian escarpment was carried out.
Extracting Long-Period Surface Waves and Free Oscillations Using Ambient Noise Recorded by Global Distributed Superconducting Gravimeters

Published: May 2020

Inversion of internal structure of the Earth using surface waves and free oscillations is a hot topic in seismological research nowadays. With the ambient noise data on seismically quiet days sourced from the gravity tidal observations of seven global distributed superconducting gravimeters (SGs) and the seismic observations for validation from three collocated STS-1 seismometers, long-period surface waves and background free oscillations are successfully extracted by the phase autocorrelation (PAC) method, respectively. Group-velocity dispersion curves at the frequency band of 2–7.5 mHz are extracted and compared with the theoretical values calculated with the preliminary reference Earth model. The comparison shows that the best observed values differ about ±2% from the corresponding theoretical results, and the extracted group velocities of the best SG are consistent with the result of the collocated STS-1 seismometer. The results indicate that reliable group-velocity dispersion curves can be measured with the ambient noise data from SGs. Furthermore, the fundamental frequency spherical free oscillations of 2–7 mHz are also clearly extracted using the same ambient noise data. The results in this study show that the SG, besides the seismometer, is proved to be another kind of instrument that can be used to observe long-period surface waves and free oscillations on seismically quiet days with a high degree of precision using the PAC method. It is worth mentioning that the PAC method is first and successfully introduced to analyze SG observations in our study.
Toward Global Earthquake Early Warning with the MyShake Smartphone Seismic Network, Part 2: Understanding MyShake Performance around the World
Authors: Kong Qingkai , Martin-Short Robert , Allen Richard M.
Published: May 2020

The MyShake project aims to build a global smartphone seismic network to facilitate large-scale earthquake early warning (EEW) and other applications by leveraging the power of crowdsourcing. The MyShake mobile application first detects earthquake shaking on a single phone. The earthquake is then confirmed on the MyShake servers using a “network detection” algorithm that is activated by multiple single-phone detections. In part two of this two-article series, we report the first-order performance of MyShake’s EEW capability in various selected locations around the world. Because of the present sparseness of the MyShake network in most parts of the world, we use our simulation platform to understand and evaluate the system’s performance in various tectonic settings. We assume that 0.1% of the population in each region has the MyShake mobile application installed on their smartphone and use historical earthquakes from the last 20 yr to simulate triggering scenarios with different network configurations in various regions. Then, we run the detection algorithm with these simulated triggers to understand the performance of the system. The system performs best in regions featuring high population densities and onshore, upper crustal earthquakes M<7.0. In these cases, alerts can be generated ∼4–6  s after the origin time, magnitude errors are within ∼0.5 magnitude units, and epicenters are typically within 10 km of true locations. When the events are offshore or in sparsely populated regions, the alerts are slower and the uncertainties in magnitude and location increase. Furthermore, even with 0.01% of the population as the MyShake users, in regions of high population density, the system still performs well for earthquakes larger than M 5.5. The details of the simulation platform and the network detection algorithm are available in part 1 of this two-article series.

Hyperbilirubinemia as a diagnostic tool in patients with perforated appendicitis: a prospective study
Authors: Gopalreddy Deepak , Jadhav Dinesh L. , Kannavar Sagar
Published: May 2020

Background: This study was conducted to determine the effectiveness of hyperbililrubinemia as diagnostic tool to predict perforated appendicitis.Methods: Patients presenting to department of general surgery of SS Medical College and Hospital during the period from June 2017 to June 2019 with features of appendicitis and liver function tests on admission undergoing laparoscopic or open appendectomy were included in this study. Age, duration of symptoms, temperature, white blood cell counts, bilirubin levels and histological data were collected. Culture and sensitivity of peritoneal fluid was done. Patients were grouped according to histological examination of appendectomy specimens and comparison was made between the groups.Results: The mean bilirubin level of all patients was 0.95 mg/dl (range, 0.1-4.3 mg/dl). The mean bilirubin levels were higher for patients with simple appendicitis compared to those with a non-inflamed appendix (0.8 mg/dl and o.5 mg/dl, p<0.001). Hyperbilirubinaemia had a specificity of 88% and a positive predictive value of 88.89% for acute appendicitis. Patients with appendiceal perforation, however, had a mean bilirubin level of 1.5 mg/dl and were more likely to have hyperbilirubinaemia (p<0.001). The specificity of hyperbilirubinaemia for perforation or gangrene was 70%.Conclusions: patients with hyperbilirubinemia and clinical symptoms of appendicitis should be identified as having a higher probability of appendiceal perforation than those with normal bilirubin levels. Hyperbilirubinemia alone is not a strong enough predictor, but might be more useful when integrated into a scoring system.

Authors: Yogish Vikram , Grover Himanshi , Joseph Sunu Ancy
Published: May 2020

Background: Tuberculosis is seen due to various factors such as overcrowding and unhygienic conditions. In order to diagnose a case of abdominal tuberculosis, a detailed history and a thorough clinical examination must be done. The objective of this article was to determine the number of patients who presented to a tertiary hospital with abdominal tuberculosis and in which of these patients management in the surgical department was required.Methods: A total of 50 patients who had abdominal tuberculosis were studied. The study was carried out at SRM Medical College Hospital and Research Center, Kattankulathur, Tamil Nadu, India. The study was carried out from February 2017 to January 2020. A detailed history was obtained and a thorough clinical examination was done. Investigations such as CBC, chest X-ray, abdomen X-ray, ultrasound scan and CT scan of the abdomen were done. When required, patients underwent surgery and the results obtained were analyzed and tabulated. In our study, out of a total of 50 patients, 32 patients were found to have required surgery. The statistics were analyzed using SPSS package 16.0.Results: It was seen that in this study, male patients were more commonly affected with abdominal tuberculosis, and resection and anastomosis was the most common surgical procedure done when required. The findings obtained were compared with other studies.Conclusions: In patients with abdominal tuberculosis, a detailed history and a thorough clinical examination are required in order to diagnose the condition as early as possible.
Study on the effect of combined action of topical silicone gel and pressure therapy in hypertrophic scar management
Authors: Das Dibyendu , Yadav Neelam , Arora Esha
Published: May 2020

Background: Widespread hypertrophic scars usually resulting from burn injuries or extensive soft tissue trauma is a common problem presented to plastic OPD. Non-invasive treatment like Pressure/compression therapy and siliconee sheets and gels are well-accepted, evidence-based recommendations for a long time. Very few studies are there for their combined effect on hypertrophic widespread scars. Aims and objectives of the study was to see the outcome of hypertrophic scar management following application of combined therapy of silicone gel and pressure garment.Methods: In the present study we have taken patients, who were randomly allotted in two groups. In one group only silicone gel was used for scar management while other group we applied silicone gel along with customized pressure garment locally for 6 months. Patients are seen in OPD monthly and after 6 months final results were analyzed, to see the effect of combined therapy.Results: Although silicone gel is alone is effective in widespread post burn scar, pressure garment provides a synergistic effects when used together. There is no significant change in colour and vascularity, but changes in scar thickness and pliability are most significant in combined therapy group.Conclusions: For small linear scar silicone gel treatment is alone sufficient, but for widespread hypertrophic scar this should always be used along with pressure garment therapy.

Published: May 2020

Background: Some of the most common wound complications following laparotomy include hematoma formation, seroma formation, wound infection, burst abdomen and wound dehiscence. Closed-suction drains (CSDs) help to drain any wound collection and also reduce any dead space in the wound thereby promoting healing and preventing complication.Methods: We conducted a prospective study and included patients presenting with acute abdomen in emergency department. Patients were selected as per inclusion and exclusion criteria. Two groups (group A and B) with equal number of patients were created based on closed envelope technique. CSD was placed in the wound of patients in group A. Wound healing and complications were compared between the two groups.Results: 50 patients were included in the study with 25 in each group. Hematoma formation was found to be significantly more among group B (24.0%) compared to group A (4.0%). Seroma formation (p value =0.03917), SSI rate (p value =0.039) and wound dehiscence/burst abdomen (p value =0.0415) was more in group B than group A. The mean wound healing time (days) and mean hospital stay (days) was significantly more in group B.Conclusions: Placing a subcutaneous vacuum suction drain at the time of abdominal wall closure during emergency laparotomy results in better wound healing and reduces postoperative wound complication, hospital stay time, morbidity and also decreases overall healthcare cost.

Background: Appendicectomy is the most common surgical procedure done for acute appendicitis worldwide. However, one among 50000 appendicectomy patients may present with recurrent abdominal pain, requiring hospitalization as stump appendicitis and may need completion appendicectomy. There are a few reports addressing management of stump appendicitis in the literature. Here we present our experience of laparoscopic completion appendicectomy over ten-year duration.Methods: A retrospective evaluation of records of appendicectomy from January 2008 to December 2018. All patients who had stump appendicitis as diagnosis and those who underwent completion appendicectomy were included. There were no exclusions. Details pertaining to presentation, duration of symptoms, records of previous surgery, perioperative and postoperative data was recorded, including follow-up of at least six months.Results: All 15 patients were managed by laparoscopic completion appendicectomy. Patients age range from 12 to 58 years, 12 were males and 3 female, duration of symptoms was from two to ten days, previous appendicectomy was done 4 to 84 months before, nine were diagnosed by ultrasonography of abdomen and six by CT scan, stump size ranged from 1 to 3.6 cm, mean operating time was 86.4 mins (range, 60-120 minutes). Duration of hospital stay was 3 to 5 days. There were no perioperative morbidity or mortality.Conclusions: Laparoscopic approach of completion appendicectomy is safe for management of stump appendicitis.

Published: May 2020

Background: The objective of the study was to validate Amit Jain’s staging system for cellulitis in diabetic and non-diabetic lower limbs and to predict the outcomes associated with cellulitis and surgical procedures done in them.Methods: We conducted a prospective study in department of surgery at Raja Rajeswari Medical College and Hospital Bengaluru, India. The study period was from December 2018 to November 2019. Statistical analysis was done using SPSS 22 and R environment ver.3.2.2.Results: A total of 36 patients were included in this study of which 21 were diabetics and were in placed in group A and 15 were non diabetics and placed in group B. 83.3% of the patients were males. 73.3% of non-diabetics had stage 1 cellulitis and 33.3% of diabetics had stage 1 and 2 each. 47.2% of patients underwent debridement and it was significantly common in diabetics (p=0.037) and also it was common in higher stages of cellulitis (p=0.001). 8.3% had amputation in this series. All the major amputations were done in stage 4 cellulitis (p=0.002).Conclusions: In this validation study, it can be seen that cellulitis is common in both diabetics and non-diabetics but it is severe in diabetic patients. Stage 3 was more common in diabetics compared to non-diabetics. Amit Jain’s staging system of cellulitis is a simple, easy, practical, focal classification that guides therapy and predicts amputation.

Primary omental infarction: a rare cause of acute abdomen
Authors: Pawar Neeraj , Kishore Anand
Published: May 2020

Primary omental infarction (POI) is a rare cause of acute abdomen. It frequently mimics other causes of acute abdomen. It is being diagnosed more frequently with the advancement of radiology. Here we report a case of a 35 years old man admitted in emergency with pain right side abdomen since past 2 days. On physical examination patient was febrile with tenderness and guarding over right side of abdomen, TLC (total leucocyte count) - 13.2×109/l, mild rise in bilirubin with rest blood investigations being normal. CT (computed tomography) abdomen was s/o omental infarction. On diagnostic laparoscopy gangrenous omentum with torsion over a vascular pedicle was noted, omentectomy was performed laparoscopically. In conclusion omental infarction should be kept as a differential diagnosis in acute abdomen especially right-side abdominal pathologies. It can be managed conservatively but if signs of sepsis are there it is wise to perform a diagnostic laparoscopy.

Published: May 2020

A hemophilic pseudotumor is one of the rare complications of hemophilia that results from repetitive bleeding, forming an expanding destructive encapsulated hematoma and necrosed tissue. It has a considerable amount of morbidity. These have become rare over the years with better treatment modalities like factor replacement. Presently, excision is the preferred treatment by many authors. There are instances where surgical excision is not feasible. In such situations, radiotherapy and arterial embolization should be considered either alone or as an adjunct to surgery. A 32 years old male patient, with severe hemophilia A diagnosed with an abdominal tumour 7 years ago during routine screening, that progressively grew to encompass the lower abdominal area. A 44 years old male patient with hemophilia A presented with slow growing swelling over the left gluteal region since, 10 years associated with ulceration and bleeding since, 3 days. The management of a patient with a haemophilic pseudo tumour is complex, with a high rate of potential complications. Surgical excision is the treatment of choice but can only be carried out by a multidisciplinary surgical team. The main postoperative complications are rebleed, infection, fistula and pathological fractures. Pelvic pseudo tumours can even become complicated by fistula formation to the large bowel and by obstruction of the ureters. Untreated pseudo tumours will ultimately destroy soft tissues, erode bone, and may produce neurovascular complications. The hemophilic pseudo tumour is a rare entity which is slow growing painless tumour, with few reports worldwide in the management of this rare complication.

Authors: Andrabi Syed Aadil Shadaab , Shah Syed Mushtaq Ahmad
Published: May 2020

Bilateral renal tumors remain relatively uncommon, accounting for 1-5% of patients with renal cell carcinoma. Most sporadic renal cell carcinomas are unilateral and unifocal. Bilateral involvement can be synchronous or asynchronous and is found in 2-4% of sporadic renal cell carcinomas. We report a case of 70 years old male who was incidentally found to have bilateral renal masses. Right sided radical nephrectomy and left partial nephrectomy was performed. Histopathological examination of the specimen revealed clear cell carcinoma and confirmed R0 resection. The patient was discharged on 7th postoperative day.

Published: May 2020

Melanomas are primarily tumours of the skin, but rarely occur at other sites like retina and anal canal. Anorectal melanoma is an uncommon condition associated with a very poor prognosis. The patient usually presents with per rectal bleed or mass. These are often misdiagnosed on presentation. Diagnosis is confirmed by biopsy. Treatment is abdominoperineal resection or wide local excision if tumour free margins can be obtained. We present a case of a 60 years old female who presented to the outpatient department with per rectal mass and bleed since 4 to 5 months and was diagnosed with melanoma anal canal on biopsy. CT scan abdomen and pelvis was done. Patient underwent abdominoperineal resection as wide local excision with sphincter saving was not possible due to the location and extent of tumour as seen on CT scan. Patient had an uneventful recovery after the procedure.
ANALYZES OF THE CONCEPTS AND MODERN MODELS OF ADULT EDUCATION IN THE EU COUNTRIES
Authors: O. Bialyk , S. Sovhira , V. Honcharuk , O. Нerasymenko
Published: May 2020

Purpose of the study: The article analyzes the modern concepts of sexual education of students, among which the most widespread is religious, hygienic, the concept of contraceptive training, the concept, and program of "content training" causes, as well as the fact of the existence of different models of sexual education of youth (restrictive, (repressive, restrictive-protective), permissive (liberal) and the model of the "golden mean"). Methodology: The study used a theoretical analysis of existing statistics gained by different countries. Leading scientists of based on the statics believe that until young people develop a deep understanding of the nature and importance of family and marriage, discussion with adults (even educators) about the process of puberty, its difficulties, sexually transmitted diseases, unconventional forms of sexual behavior and similar topics needed. Main findings: The methodology of ambushing the statistical vigor is encouraged by the humanities and the science-realistic ideas and concepts, we know that you can find more information about how to learn more about the statutory article of the article. In this regard, some models were established. According to the study, neither of the introduced models is worse or better than the other. Social Implications: a modern outlook on the interpretation of gender issues and the prediction of future youth in the theory and practice of sexual education in the EU countries. In the permissive model, at first glance, sexual behavior is placed on a par with all other behaviors and is therefore dependent on general laws of social and ethical regulation. Originality/Novelty of the study: modern trends of sexual education of student youth in EU countries are generalized and strengthening the socio-cultural context of sexual education content.

The labour intensive nature of Zimbabwean agriculture demands that farmers meet excessive labour requirements, at the same time keeping labour costs as low as possible to guarantee profits and achieve maximum business performance. This study, carried through a questionnaire survey, at the Hunyani Matura Farm, in the Zvimba district of Zimbabwe between from October 2017 to March 2018, investigated the effect of employment mode on turnover and agri-business performance. Data collected from the participants, was compared with the information from secondary source documents. From the results temporary workers performed better than permanent workers and they cited problems of low wages, poor working conditions, high work targets, inequality in work allocation, job insecurity and constant shuffling. Temporary workers had higher turnover and turnover intentions than permanent workers. Temporary employment mode had a positiveeffect on agri-business performance. This study recommends the use of permanent employment mode on key positions like forepersons, stores persons and supervisors, and temporary employment mode on general farm tasks, while seasonal contracts were seen good for skill demanding operations such as tobacco seedbed establishment, tobacco reaping and curing and grading. A ccareful selection of employment modes reduces inequalities and unhealthy attitudes at work and improves on farm business performance.

Authors: Tempere Sophie , Sicard Gilles , De Revel Gilles
Published: May 2020

One of the characteristic symptoms caused by SARS-CoV-2 is a totally or partially altered sense of smell; which may or may not be combined with an altered sense of taste. This alteration appears to last anywhere from ten days to several weeks. It’s not always easy, in our daily routines, to self-assess and notice a decline or change in the acuity of our sense of smell or taste. Yet, performing an effective olfactory-gustatory test is quite straightforward.
