Aim of the study: Clarification for the time of the clinical improvement after management COVID-19 pneumonia versus normal gradation of common workup is the target for the current study. Background: COVID-19 pneumonia is a current serious international pandemic infection. Generally, in medical diseases, the clinical response is commonly parallel to laboratory and radiological improvement. This rule may be different in COVID-19 pneumonia. Method of study and patients: The author reported retrospective-observational 47-case report series. The study was conducted in a physician outpatient clinic thorough nearly 12-months, starting from Jun 9, 2020, and, ended on May 8, 2021. All included cases were COVID-19 pneumonia and treated with conventional antibiotics, anticoagulants, and steroids. Results: The mean ±SD age was: 50.08 (14.9) years, with male sex predominance (55.32%). The mean days of clinical versus leukocytosis, neutrophilia, and lymphopenia improvement (0.84 ±0.49, 13.05 ±6.44, 13.05 ±7.01, 13.05 ±7.01).The mean ±SD days of clinical versus CRP, D-dimer, s. ferritin, and LDH improvement (0.84 ±0.49, 12.2 ±3.25, 12.2 ±6.21, 12.3 ±5.46, 20.92± 9.48). The mean days of clinical versus radiological and electrocardiographic improvement (0.84 ±0.49, 15.74 ±5.25, 11.45 ±5.45). The test was statistically significant in all the above tests (p-value is < .00001) Conclusions: Yasser’s COVID-19 Discrepancy phenomenon is a novel descriptive phenomenon that is always seen in all COVID-19 pneumonia. Initial dramatic improvement of the clinical status of COVID-19 pneumonic patient, not a simultaneously after the management, not a coincide with laboratory, radiological, and electrocardiographic workup. Further larger studies for the study medical regimen with considering of “Yasser’s COVID-19 Discrepancy phenomenon” is recommended.

Objectives: To determine the variation of d-dimers in COVID-19. To determine the contribution of demographic factors (age and gender) toward an elevated d-dimers values. To determine the probability of surviving in different age groups in COVID-19, with d-dimer > 0.5 µg/ml. Methodology:  A total of 193 patients were enrolled from COVID-19 isolation units, Hayatabad medical complex Peshawar, whose d-dimer levels were performed as per instructions of the treating physician and were followed. Relevant information’s were recorded on a pre-designed performa prepared in accordance with the objectives of the study. Results: Out of total 193 patients 152(78.8%) were males and 41(21.2%) females. 94(48.7%) patients were in the age range 35-55 y while 76(39.4%) patients had age more than 55 y. Regarding d-dimer readings, 162(83.9%) had d-dimer levels more than 0.5 µg/ml. The mean with standard deviation of age of the patients was 52 ± 13 y. The mean with standard deviation of d-dimer values of the patients was 4.9 ± 13.3 µg/ml. It was observed that, the relative risk of deranged values of d-dimers was 1.18 (rr = 1.18) in patients with age > 55 y. Similarly in female gender the relative risk of higher values of d-dimers above normal was 1.26 (rr = 1.26) without reaching a statistically significant p-value (p = 0.48). The probability of worse outcome in term of death was 2.06 times more in patients with d dimers > 0.5 µg/ml (OR = 2.06). Furthermore the probability of surviving was 90-100% by age < 50 y, 80% in age range 51-60 y, 45% in age range 61-70 y and 30% at age  > 80 y. Conclusion: The deranged d-dimer levels were noted in 84% of the COVID-19 patients. Age > 55 y and female gender are at higher risk of deranged d-dimers and further consequences. Survival rate of patients with deranged d-dimers drops to 30% in patients with age > 80 y, 45% at age < 70 y.

Abstract The present study aimed to establish the morphometric brain changes during aging in a necropsy series from Brazil and determine whether sexual dimorphisms interfere in these changes. Methods: A cross-sectional study was conducted at the São Paulo Autopsy Service in Brazil where, after informed consent, data was gathered from next of kin interview with reference to clinical status prior to death. Brain weight, volume and density measurements were taken and then adjusted for head circumference. Descriptive statistics and tests of hypothesis and correlations were applied, considering a p-value of 0.05. Results: 414 subjects, mostly men (60.4%), with a mean age of 67.1 years, were included. The mean brain weight of the sample was 1219.2g±140.9 and mean volume was 1217mL±152.3. The mean brain density of the sample was 1.0g/mL±0.09. Values differed between males and females in terms of weight and volume. Brain weight decreased during aging by about 45g per decade (r= -0.300; p<0.01) and volume by about 43mL (r= -0.278; p<0.00). Mean density of the sample was 1.0 g/mL in both genders. Conclusions: Brain weight and volume (with or without corrections) decreased during aging, and these reductions were more pronounced in women. Density remained unchanged for both genders. Further studies are needed to investigate factors associated to these reductions.

Aim: This study was aimed to evaluate the association between serumD-dimer, serum Ferritin with disease severity in patents havingCOVID-19. Methods:Total 80 confirmed COVID-19 patients were enrolled in this cross sectional study. Samples were assessed by positive SARSCoV- 2 by RT-PCR testing and were collected from two tertiary Hospitals(IbnSina Medical College Hospital and Ibrahim Cardiac Hospital and Research Institute).We also performed CT findings of COVID patients with or without pulmonary involvement. COVIDpositive patients were divided into two groups (Group 1 and Group2) according to lungs involvement confirmed by CT-scan. In this analysis, several variables such as gender, age, D-dimer and serum ferritin were taken. Results: The Mean of D-dimer in Group-1 subjects was 4.26±3.60mg/L and in Group-2, this was 0.59±1.08mg/L. So D-dimer level was significantly raised in COVIDpneumonic patient (P value = <0.001). The mean of ferritin(554.65±515.841)ng/ml for pneumonic patient was also highly significant than the mean(133.70±109.22)ng/ml of COVID without pneumonia. Conclusion:D-dimer and S. ferritin were elevated in patients with COVID-19. These two reliable biomarkers are correlate with the disease severity and useful for better management of COVIDpositive patients. Bangladesh Journal of Medical Science Vol.20(5) 2021 p.166-170

Blood Lactate Levels

Abstract Background and objectiveIn severe sepsis, increased blood lactate levels are observed indicating impaired oxidative phosphorylation, which secondarily causes hypoxic hypoxia and stagnant tissue hypoxia. Among all other related factors, a high rise of the lactate level in blood may be a useful predictor of sepsis patients' mortality. This study aims to determine the association of consecutive blood lactate levels with the patient's mortality with sepsis admitted in the Critical Care Unit (CCU). MethodsThis prospective study included 50 patient of septicemia at CCU above 18 years in a tertiary care centre. On admission, at 24 hours and 72 hours, blood lactate levels were monitored. Their clinical status was evaluated for 28 days to categorise as survivor and non-survivor. The statistical analysis was made with Microsoft Excel and SPSS version 20. To test the difference in mean blood lactate levels among survivors and non-survivors Student’s t-test was applied. A p-value of less than 0.05 was considered significant. Prior ethical clearance from the institutional ethics committee of human with informed consent from the patients was obtained for data collection.ResultsThe current study included 50 patients of septicemia, 23 were survivors, and 27 were non-survivors after 28 days of follow up. The mean lactate range for the 23 survivors was ranged from 0.43 mmol/l to 5.69 mmol/l, whereas for non-survivors, it was 1.64 mmol/l to 6.14 mmol/l. The mean value of lactate for the survivors and non-survivors during admission, at 24 hours and at 72 hours were 0.9545±0.45798 vs 2.5204±1.51498, 1.2461±1.21360 vs 2.5107±1.63678 and 1.5496±1.66788 vs 2.7904±2.00160. The differences between the mean lactate values between survivors and non-survivors at different time intervals were highly significant.ConclusionA slower rate of lactate clearance during hospitalisation may be a significant factor associated with severe sepsis patient mortality. Thus serial blood lactate levels is a significant predictor of mortality and should be monitored.

Community-acquired Pneumonia (CAP) is an infection of the lung parenchyma that is acquired outside of hospital, [1] involved approximately 150 million new cases annually, among children younger than 5 years old worldwide. We retrospectively evaluated the effect of Prednisolone in 89 children with CAP who were admitted to the 2nd hospital of Shandong University (China) and Infectious diseases of Andijon region (Uzbekistan).  The mean age was 6.3 in China (Placebo) and 9.3 in Uzbekistan (control) years, 54% and 52% of them were boys respectively. All children had received broad spectrum antibiotics (cephalosporin) or Macrolides (Azithromycin) and Oxygen. In addition to these we added Prednisolone 1 mg/kg on day 2 of admission to control group. 24 (68.5% from all febrile) children were became afebrile within 24 hours after Predisolone use on day 3 of admission, and their clinical status developed in control group, when it was achieved on day 7 in Placebo group. Hospital days also shortened in control group (6 days) than placebo (8 days) (p value ≤ 0.01). In conclusion, steroid therapy helpful for reducing hospital stay and morbidity in children with community-acquired Pneumonia and no observed side effects.

Background: The visual evoked potentials (VEP) is a valuable tool to document occult lesions of the central visual channels especially within the optic nerve. Objectives: The purpose of the present study was to observe the findings of first few cases of VEP done in the neurophysiology department of the National Institute of Neurosciences (NINS), Dhaka, Bangladesh. Methodology: This cross-sectional study was conducted in the Department of Neurophysiology at the National Institute of Neurosciences and Hospital, Dhaka, Bangladesh from September 2017 to March 2020. All patients referred to the Neurophysiology Department of NINS for VEP were included. Pattern reversal VEPs were done using standard protocol set by International Federation of Clinical Neurophysiology (IFCN). Results: The mean age of the study population was 30.70 (±12.11) years (6-68 years) with 31 (46.3%) male and 36 (53.7%) female patients. The mean duration of illness was 8.71 (±1.78) months (3 days- 120 months). Most common presenting symptom was blurring of vision (37.3%) and dimness of vision (32.8%). Patterned VEP revealed mixed type (both demyelinating and axonal) of abnormality in most cases [29(43.35)]. The most common clinical diagnosis was multiple sclerosis (29.85%) and optic neuropathy (26.87%). In the clinically suspected cases of multiple sclerosis, optic neuropathy and optic neuritis most of the cases of VEP were abnormal and the p value is 0.04 in optic neuropathy and optic neuritis. Conclusion: The commonest presentation of the patients in this series were blurring of vision and dimness of vision. The most common clinical diagnosis for which VEP was asked for, was optic neuritis and multiple sclerosis. Most abnormalities were of mixed pattern (demyelinating and axonal).

This study aims to investigate whether the use of six selected short stories throughout the duration of a 14-week course could enhance students’ reading comprehension achievement at the end of the semester. Out of the six short stories read, three were chosen as in-class assignments known as ‘Personal Reading Logs’ (hereafter, PRLs). One group of semester two Diploma students taking a reading skills course was selected through a convenience sampling method. A pre-test was conducted by having the students answer a past semester reading quiz of which the results would then be compared to their post-test (final reading exam) results. A paired samples t-test revealed no significant difference in the reading scores of the pre-test and the post-test, t (17) = -.265, p > .05. Since the p-value was bigger than 0.05, this indicated that the mean reading score of the post-test (M = 50.556) was not significantly higher than the mean reading score of the pre-test (M = 49.722). Therefore, the null hypothesis which stated that there was no difference in the mean score of the pre-test and post-test was retained. Overall, the result refuted the findings of other studies promoting the effectiveness of using short stories to enhance L2 reading comprehension achievement.

ABSTRACT:Anti-dumping on tinplate products aim to protect domestic industries. Still, some industries want tinplate products not to be subject to anti-dumping because domestic production is not sufficient. This research examines the application of anti-dumping import duties on tinplate products from China, Taiwan, and Korea from 2014 to 2018, to know whether there are differences in the value of imports before and during the anti-dumping import duty. Use secondary data sourced from UN-Comtrade. Samples are selected by countries that have continuously sent tinplate products to Indonesia from 2010 to 2018, namely China, Taiwan, Korea, Japan, Germany, India, and Malaysia. Using the Mean Equality Test, it is known that there are differences in the import value before and during the anti-dumping import duty, with a p-value of 0.0114 less than α (0.05), so it is concluded that there is a difference in the import value of the tinplate product before and during anti-dumping duty. Descriptive analysis results illustrate imports from China and Taiwan tend to decrease. In contrast, imports from Korea tend to increase despite being subjected to anti-dumping duties because they can compete by using preferential tariffs based on free trade schemes.Keywords: Antidumping, Import duty, TinplateABSTRAK:Anti-dumping terhadap produk tinplate bertujuan melindungi industri dalam negeri, akan tetapi terdapat ìndustri yang menginginkan produk tinplate tidak dikenakan anti-dumping karena produksi dalam negeri belum mencukupi. Penelitian ini menguji penerapan bea masuk anti-dumping terhadap produk tinplate dari China, Taiwan dan Korea selama tahun 2014 s.d. 2018, dengan tujuan mengetahui apakah ada perbedaan nilai importasi sebelum dan selama dikenakan bea masuk anti-dumping. Menggunakan data sekunder yang bersumber dari UNComtrade. Sampel dipilih negara yang secara kontinyu mengirim produk tinplate ke Indonesia sejak 2010 s.d. 2018, yaitu China, Taiwan, Korea, Jepang, Jerman, India dan Malaysia. Menggunakan Mean Equality Test, diketahui terdapat perbedaan nilai importasi sebelum dengan selama dikenakan bea masuk anti-dumping. Hasil penelitian menunjukkan bahwa nilai-P (p-value) adalah 0,0114 lebih kecil dari alpha (α=0,05), sehingga disimpulkan terdapat perbedaan pada nilai importasi produk tinplate sebelum dengan selama dikenakan bea masuk anti-dumping. Hasil analisis deskriptif menggambarkan importasi dari China dan Taiwan cenderung menurun sedangkan importasi dari Korea cenderung naik walaupun dikenakan bea masuk anti-dumping karena mampu bersaing dengan menggunakan tarif preferensi berdasarkan skema perdagangan bebas.Kata Kunci: Anti-dumping, Bea Masuk, tinplate

Abstract Magnetic current imaging (MCI) using superconducting quantum interference device (SQUID) and giant-magnetoresistive (GMR) sensors is an effective method for localizing defects and current paths [1]. The spatial resolution (and sensitivity) of MCI is improved significantly when the sensor is as close as possible to the current paths and associated magnetic fields of interest. This is accomplished in part by nondestructive removal of any intervening passive layers (e.g. silicon) in the sample. This paper will present a die backside contour-milling process resulting in an edge-to-edge remaining silicon thickness (RST) of &lt; 5 microns, followed by a backside GMR-based MCI measurement performed directly on the ultra-thin silicon surface. The dramatic improvement in resolving current paths in an ESD protect circuit is shown as is nanometer scale resolution of a current density peak due to a power supply shortcircuit defect at the edge of a flip-chip packaged die.
