Authors: Abhilasha Abhilasha , Soni Sweta , Rakesh Amrita , Patni Nidhi
Published: August 2020

ABTRACT- Prostate cancer is second most frequent cancer in men and fifth leading cause of death worldwide. Most radiotherapy patients with prostate cancer are treated with intensity modulated radiotherapy. IMRT requires high spatial accuracy in localizing the target volume and high precision in treatment delivery, because even a small geographic miss can have a large dosimetric effect. However, the patient setup position and anatomy changes daily, particularly in the prostate region, due to rectum and bladder filling. Materials Methods: We analyzed 30 patients with prostate cancer patient treated with IMRT kV CBCT was performed for each patient twice per week during the entire course of treatment. The bladder, rectum, prostate and PTV were contoured on each CBCT scan. Results: Delivered dose of prostate D95% and prostate D100% was 99.15% and 93.66% respectively and mean value of V70 for bladder was 16% and delivered value was 16.45%. Whereas the mean value of V70 of plan for rectum was 18.12% and delivered value was 27.58%. Conclusion: Interfractional variation during prostate radiotherapy can results in substantial difference between planned and delivered doses, particularly in critical structure. IG-IMRT is useful tool in assessing dosimetric changes in critical structure due to interfractional anatomical interfractional anatomical variation in prostate radiotherapy.

Introduction: Electrolytes are very essential for normal functioning of vital organs including heart. Electrical activity of the heart is regulated by Na, K and Ca. Normal homeostasis of these electrolytes are vital for normal functioning of heart. Electrolyte imbalance is often common after episode of acute coronary syndrome (ACS) and electrolyte imbalance may have important role in altering the prognosis of ACS.
Aims & Objectives: To assess the serum electrolytes imbalance (Na, K and Ca) in ACS patients within first 48 hours of onset of symptoms.
Materials and Methods: This hospital based cross sectional study conducted on 50 cases of ACS and 50 healthy controls. Serum Na, K and Ca (total) concentration were estimated in healthy controls and newly diagnosed cases of ACS within 48 hours of onset of symptoms.
Result: Mean value of serum Na, K and Ca (total) in case and control group were 138±4.23 and 140±1.99 mEq/L (p=0.0018), 3.87±0.43 and 4.16±0.35 mEq/L (p=0.0006), 8.85±0.59 and 9.68±0.44 mg/dL (p<0.0001) respectively. Hyponatremia, hypokalaemia and hypocalcemia were found in 14% (n=7), 12% (n=6) and 18% (n=9) of ACS patients respectively.
Conclusion: There were statistically significant lower levels of serum Na, K and Ca (total) found in ACS patients compared to healthy controls.

Published: August 2020

Objective : To estimate the prevalence of dry-eye disease (DED) among medical professionals in a tertiary care hospital in Western UP during the lockdown period 2020. Materials & Methods : This was a cross-sectional hospital-based, observational study from 7th May 2020 till 14th May 2020, that included 50 medical professionals as subjects. The study compares the increase in the number of hours spent on Visual Display Terminals (VDTs) before and during the lockdown period 2020. This in-turn led to numerous ill-effects on human beings, out of which ocular manifestations like dry-eye disease has been on the rise. The study has been carried out in the form of questionnaire survey data – Ocular Surface Disease Index (OSDI) asking about the symptoms and various other parameters, related to dry eye. Results : The mean number of hours spent on VDTs before lockdown was 2.82±1.32 hours and during lockdown was 6.26±4.76 hours. In accordance with the OSDI scoring, 23/50 subjects developed DED. Out of these, 28% (14/50) had mild DED, 16% (8/50) had moderate DED, and only 2% (1/50) had severe DED. Prevalence of dry eye was directly proportionate to exposure time to VDT during the lockdown. Conclusion : The prevalence of dry-eye disease (DED) among medical professionals during the lockdown period 2020 was 46%. This was attributed to the increased dependence on VDTs for various purposes.

Published: August 2020

Difficult airway management has till date been the most fearsome and challenging part of any anaesthetic management. Meticulous planning is always done prior to anaesthetic induction of such patients with multiple back up plans and rescue strategy. Significant advancements in terms of clinical protocols, techniques, and devices / gadgets in this field have led to decreased incidence of airway related complications. We hereby present a case series of 3 clinical cases with different airway scenarios; 1) Patient with huge goiter, who was intubated with the help of an indigenously developed fish mouth valve device, 2) a temporomandibular joint ankylosis case, managed with awake fibreoptic guided intubation 3) Patient with post burn contracture of face and neck, in which fibreoptic intubation was performed after partial release of scar under tumescent anaesthesia. Extensive preoperative airway evaluation and preparation to handle any emergency by multiple backup plans always helps in smooth sailing through these difficult clinical scenarios

Background/purpose: The purpose of the present study was to evaluate the role of laparoscopy in diagnosis the cases of chronic pelvic pain.
Methods: This prospective study was conducted among 100 women who had been suffering from chronic pelvic pain for ≥6 months at Department of Obstetrics & gynaecology, Muzaffarnagar Medical College, Muzaffarnagar from December 2017 to December 2018. After proper selection of cases, a detailed history followed by general, systemic and pelvic examination, diagnostic laparoscopy of the patient was done and noted as per the following protocol. Diagnostic laparoscopy was performed under general anaesthesia using a 5-mm Karl Stortz 30° angle double port laparoscope. The data was collected and subjected to statistical analysis using SPSS version 22.00
Results: Majority (70%) of patients with CPP were in the age group between 26 – 30 years and 31 – 35 years. Two most common causes of CPP detected clinically were endometriosis and chronic PID which together constituted about 56% of the cases with CPP in our study group. Laparoscopy findings revealed that 90% of patients with CPP have one or more positive findings, the commonest being endometriosis in various pelvic sites with or without endometrioma (34%)
Conclusion: It can be concluded that ideally hysteroscopy should be performed simultaneously to identify intrauterine pathologies, which can be associated with CPP and which are missed by laparoscopy. Hence combined laparohysteroscopy is the ideal method for diagnosis of CPP.

EVALUATION OF THYROID FUNCTION STATUS IN SONOGRAPHICALLY SUGGESTED FATTY LIVER SUBJECTS
Authors: Singh Amrendra Kumar , Gunjan Gagan , Choudhary Rajkamal , Jana Debarshi
Published: August 2020

Objectives: The liver metabolizes thyroid hormones and thereby influences the regulation of their systematic endocrine effects. On the other hand, thyroid hormones play an important role in hepatic lipid homeostasis. Several studies addressed the association between thyroid function tests and non alcoholic fatty liver disease. The results of those studies indicate that hypothyroidism might be related to non alcoholic fatty liver disease. The recognized link between hypothyroidism and elements of metabolic syndrome may explain this relation. The present study was performed to evaluate the thyroid function status with the severity of sonographically suggested fatty liver subjects.
Materials and Methods: This cross sectional study was carried out at the Department of Medicine of Jawaharlal Nehru Medical College & Hospital, Bhagalpur, Bihar during the period of June 2019 to May 2020. A total number of 155 consecutive patients having sonographically detected fatty liver from the above mentioned hospitals were included in this study and they were divided into three grades depending on the sonographic criteria. Data were analyzed between these three grades in respect of age, sex, BMI, thyroid hormone levels (FT3, FT4 and TSH), fasting lipid profile and serum liver enzyme levels.
Results: 82 (52.9%) patients had grade 1, 50 (32.3%) had grade 2 and 23 (14.8%) had grade 3 fatty liver. The mean age was found 39±10.9 years in Grade 1, 39.5±10.4 years in Grade 2 and 41.4±7.1 years in Grade 3. The difference was not statistically significant (p>0.05) among three groups. Male to female ratio was almost 2:3 in the whole study subjects. The mean BMI was significantly higher in grade 3 (p<0.05) followed by grade 2 and grade 1. 128 (82.6%) patients were euthyroid, 23 (14.8%) were subclinical hypothyroid and 4 (2.6%) were hypothyroid. In Anova test, the mean FT3 and FT4 were significantly declined (p<0.05) with increased grade but the mean TSH level was significantly increased (p=0.001) with increased grade of fatty liver. The Spearman’s rank correlation test shows that no significant but a negative correlation (r= -0.101; p=0.175) was found between FT3 and fatty liver of the study patients, but a significant negative correlation (r=-0.277; p=0.001) was observed between FT4 and fatty liver of the study patients. On the other hand a significant positive correlation (r=0.325; p=0.001) was observed between TSH and fatty liver of the study patients.
Conclusion: In this study it has been found that thyroid hormone levels are significantly decreased with increasing grades of fatty liver detected by ultrasound. The underlying pathophysiology for this association is still not clear, however several mechanisms have been proposed. So the findings of this study will inspire other researchers to evaluate the thyroid function status with the severity of sonographically suggested fatty liver in larger scale.

Authors: Gour Prajwaljeet , Sarjare Deoyani , Wani Kalyani , Yeshwante Sandhya
Published: August 2020

Introduction:
Placenta accreta (PA) includes various types of abnormal placentation in which chorionic villi attach directly to or invade he myometrium. There is a rising trend of placenta accreta owing to increased number of primary and repeat Caesarean sections. Accurate and timely identification of affected pregnancies allows optimal obstetric management to reduce maternal morbidity and mortality. The availability of conservative treatment modalities for the management of post partum hemorrhage arising from the same mandates the use of magnetic resonance imaging (MRI) to precisely evaluate the degree of placental invasion so as to further guide the treatment options.
Materials and Methods:
In two years observational cross sectional study, 18 pregnant females between age group 15-40 years were subjected to MRI pelvis and MRI findings were noted.
Result :
Placenta accrete vera was the most common type found in our study. Patients with placenta previa and previous Caesarean section were at highest risk. Intraplacental bands, heterogenous placenta, lumpy placental contour were the most commonly observed findings.
Conclusion:
MRI is very useful for accurate evaluation of placenta accreta particularly when USG findings are ambiguous or when there is a posterior placenta. There is increased incidence of placenta accreta with multiparity, placenta previa and history of previous Caesarean sections.

Published: August 2020

As a result revealed, dominance of white mold stem forms on pea plants has been revealed. The symptoms of the disease were characterized by changing signs: the formation of moisture-rich areas, the formation of a white cotton-like mycelium and sclerotia of the pathogen, bleaching and cracking of diseased stems. It was established that, depending on the degree of development of the disease, the amount of beans formed on the plants decreased from 0.9 pieces up to 9.0 pcs. In variants with the initial degree of development of the disease, no affected white rot was found. At the same time, with an increase in the intensity of the development of the disease on pea crops, the number of infected beans increased. The negative effect of white pea stem mold on seed yield was revealed. With the maximum development of the disease on pea stalks (grade 3), the mass of 1000 seeds decreases by 92 g.

One of the methods for improving the bearing capacity of the construction structures and engineering constructions is the application of construction materials with the improved strength and flexibility characteristics as well as the ability to disperse the vibration energy. It is of particular importance for the construction structures being in the seismic regions, which are under dynamic loading during their operation. The shape Memory Alloys (SMA) are promising materials, which can recover their original shape after uploading (the effect of superelasticity) or being under the temperature influence (the effect of shape memory) during many cycles of loading – unloading.
The mechanical behavior of a reinforced concrete beam with classical reinforcement and a reinforced concrete beam reinforced with inserts of superelastic Nitinol (Ni-Ti) is simulated by the finite element method. Beam dimensions: h=140 mm; b=80 mm; L=1200 mm. The beam is made of concrete of the С20/25 class, armature         А400С 2Ø12mm L=1080 mm; mountings armature А240С 2Ø6mm L=1200 mm, reinforcing insert Ni-Ti 2Ø12 mm L=120 mm. Behavior simulation took place in the ANSYS Workbench 19 R2 PC environment. Reinforced concrete beam is divided into finite elements. Size of the Solid 186 elements for the armature 12,5 mm, for the mountings armature 40 mm. The size of the Solid 186 elements for the body of the beam was automatically selected by the software – 200 mm. In total, the reinforced concrete beam consisted of 22872 finite elements and 4730 nodes. Reinforced concrete beam with armature A400C is subjected to evenly distributed load on the plane 120×80 mm (Р = 20MPa). It is revealed that the transition of the yield strength in the simulated beam with armature А 400С occurs at a load of Р = 9MPa. Therefore, the study of the behavior of the reinforced concrete beam with classical reinforcement (armature A 400C) and the reinforced concrete beam reinforced with inserts of superelastic Nitinol (Ni-Ti) occurred when loading beams to the value of Р = 9MPa and their complete unloading. The insert of nickel-titanium (Ni-Ti) alloy replaced the plastically deformed section of the working reinforcement A400C, where the stresses exceeded the yield strength (σt 0.2 = 365 MPa).
The values of displacements, maximum stresses and residual stresses of the beams by compared. It was concluded that the inserts made of superelastic Ni-Ti alloy 16,9 times reduced the εres of the working reinforcement, increased the maximum displacement of the beam by 9,7%, increased the εmax by 47,8% compared to the working reinforcement А400C.

Methodological studies on the precision of variety trials with sugar beet – effect of sample size and head rows
Authors: Kenter Christine , Götze Philipp , Ladewig Erwin
Published: August 2020

In Germany, the guidelines for variety trials with sugar beet require plots with 80–100 beets for a representative estimation of root yield. If possible, one or two head rows shall be planted perpendicular to the plots to avoid border effects at open alleys. The optimum sample size was determined in the 1970s and the effect of head rows has not yet been systematically studied. The aim of the present study was to quantify the effects of sample size and head rows on the precision of yield and quality data of sugar beet. Two series of field trials were carried out in Germany in 2016–2017. In the series “sample size”, conducted at 9 environments, samples of 30, 60, 90 and 120 beets were compared. With increasing number of beets, coefficients of variation and least significant differences for yield and quality parameters decreased, especially when the sample size was increased from 30 to 60 beets. Compared to the current standard of 90 beets, the precision of samples with 60 beets was similar for sugar content but lower for root yield. It is concluded that the current sample size should not be reduced. In the series “head rows”, ten variety trials were conducted without and with head rows. The precision of trials with and without head rows did not differ in general. The effect of head rows on least significant differences for root yield and sugar content was not consistent among environments. With head rows, absolute root yield (tonnes per ha) was lower and sugar content was higher than without, but the rank of varieties in relative white sugar yield remained unchanged. Sugar beet varieties can thus be tested in trials with and without head rows without losing precision, even within the same trial series.

Published: August 2020

Two separated sets of laboratory experiments were studied for barley seeds treating using a microwave and ultraviolet irradiation. In the microwave set, seeds have been exposed to the microwave radiations (2450 MHz) for 0 sec (control, MW0), 5 sec (MW1), 10 sec (MW2), and 20 sec (MW3), while in the ultraviolet set, seeds have exposed to UV-C radiation (254 nm) for 0 min (control, UV0), 30 min (UV1), 60 min (UV2), and 120 min (UV3). The aim is to study the influences of different exposure time from MW and UV-C radiation on some barley seed germination parameters and to choose the fitting model Logistic (Log) or Gompertz (Gom) suited to cumulative germination curves under the influence of these factors.  The results of this study showed higher seed germination percentage (93.33%) at the exposure time MW2 and UV3 (88.33%), whereas the lowest value (66.67%) recorded in MW3 treatment. The results also appeared the best values at MW2 in SG, 6.24 seed day-1; in GRI, 31.19% day-1, and in GI, 87.67, as well as at UV2 in MGT, 3.32 day. The higher value of asymptotic germination barley seeds was found with Gom function (97.24%, and 88.71%) at MW2 and UV3, respectively. Besides, Gom functions at MW1 and UV2 give the highest maximum germination rates at 2,08 and 2.51% h-1, respectively. The results of the Log equation illustrated the highest value of germination percentage of the inflection point has recorded in 43.85 and 47.37 % on UV3 and MW2 treatments, respectively. For the fitting growth curve, the results have proven that the Gom function was shown the lowest values in MSE in all MW and UV exposure times, as compared with the Log function. So, the results of the Gom function were more fit for the growth curve for MW and UV treatments, as compared with the Log function.

The Ghana government proposed to implement school-based assessment (SBA) in all pre-tertiary education institutions to replace the continuous assessment in 2007. However, any research is yet to be conducted in Biakoye District to find out the benefits of school-based assessment in the teaching and learning of Social Studies. This study examined the benefits of school-Based Assessment as an innovation in Ghanaian educational system in the learning of Social Studies. The descriptive survey was adopted by the study. A total of 40 Social Studies teachers from Biakoye District were purposively selected for the study. It was found that even though the majority of the Social Studies teachers have never attended workshop on the use of SBA, they implemented it in assessing students. The Social Studies teachers used for the study also indicated that the SBA has a lot of benefits in the teaching and learning of Social Studies. The study recommends that workshops should be organized for teachers on SBA so that they could use it effectively.

This study investigates the mall's Indoor Air Quality (IAQ) to compare changes in levels of Volatile Organic Compounds (VOCs) concentration in the morning and evening. It also explores the sources of emission released that could be related to occupants' health status (dizziness, headaches, flu, running nose, nose stuffy, nose irritation, eye irritation, watery eye, and eye reddening). A questionnaire survey approach was used to collect quantitative data involving 32 workers from malls in Malacca, Malaysia. This study established models to measure changes in VOCs level in two different sessions for a given area. Also, predictors related to the work context (human performance and condition) were found to be significantly related to occupants' symptoms. Two significant values identified the changes in VOCs concentration for morning and evening sessions in the lobby, bakery, eye ware shop, mobile centers, and supermarket. No evidence supports the exposure towards the personal individual in the present findings. This study contributes to the literature on levels of VOCs in the shopping mall as well as the emission sources. It also suggests that more comprehensive monitoring can be achieved, particularly in the context of Malaysia.

Public transportation is one of the most important services in supporting the smooth running of community activities in cities where people most commonly use a bus to reach a destination. Consequently, it requires a clear travel route so passengers find it easy to go on a trip. Display is a device for providing information. However, the existing display receives some complaints where more than 60% of passenger experience difficulty in reading what is shown, taking more time for them to understand the information. It is evidence that the device is not effective and efficient to use. Thus, development of a new display is crucial. The purpose of this study was to design an innovative display that is more ergonomic in displaying bus route information. Survey was conducted to identify user requirement. Axiomatic design method was applied to determine the design parameters of the display by mapping process from customer attribute and functional requirement on the basis of the ergonomic principles. Statistical analysis was conducted to test hypothesis. The result of this study showed that the display developed is valid to meet customer criteria at 5% of significant level, covering the criteria of being informative (0.144), comfortable (0.063), digitalized (0.070), and easy to access (0.378). Thus, it is more effective and efficient for passengers to gain any information needed.

One of the common health problems for small and medium enterprise such as batik production is work-related musculoskeletal disorder (WMSD). This health problem may contribute to long-term medical effect on the production workers. For batik stamping workers, the load of the copper block that need to be used repetitively can reach up to 2kg. This study aims to reduce WMSD effect by reducing the lifting load of the cooper block handled by the batik stamping worker. The worker’s working load is observed before the intervention process by using one of the ergonomic risk assessment tools, Rapid Upper Limb Asssessment (RULA). The ergonomic intervention designed in this study is from the engineering approach by modifying tools. It is found out that the intervention done were able to eliminate the lifting load handled by the worker to avoid discomfort or further health complication. This outcome are hoped to be able to improve workers’ health and increase batik stamping work productivity that eventually increased company’s revenue.
