Abstract
The first detection of a human infection with avian influenza A/H6N1 virus in Taiwan in 2013 has raised concerns about this virus. During our routine surveillance of avian influenza viruses (AIVs) in live-bird markets in Egypt, an H6N1 virus was isolated from a garganey duck and was characterized. Phylogenetic analysis indicated that the Egyptian H6N1 strain A/Garganey/Egypt/20869C/2022(H6N1) has a unique genomic constellation, with gene segments inherited from different subtypes (H5N1, H3N8, H7N3, H6N1, and H10N1) that have been detected previously in AIVs from Egypt and some Eurasian countries. We examined the replication of kinetics of this virus in different mammalian cell lines (A549, MDCK, and Vero cells) and compared its pathogenicity to that of the ancestral H6N1 virus A/Quail/HK/421/2002(H6N1). The Egyptian H6N1 virus replicated efficiently in C57BL/6 mice without prior adaptation and grew faster and reached higher titers than in A549 cells than the ancestral strain. These results show that reassortant H6 AIVs might pose a potential threat to human health and highlight the need to continue surveillance of H6 AIVs circulating in nature.

Abstract
BACKGROUND High-power short-duration (HPSD) ablation has emerged as an alternative to conventional standard-power long-duration (SPLD) ablation. We aim to assess the efficacy and safety of HPSD versus SPLD for atrial fibrillation (AF) ablation. METHODS A systematic review and meta-analysis of randomized controlled trials (RCTs) retrieved from PubMed, WOS, SCOPUS, EMBASE, and CENTRAL were performed through August 2023. We used RevMan V. 5.4 to pool dichotomous data using risk ratio (RR) and continuous data using mean difference (MD) with a 95% confidence interval (CI). PROSPERO ID CRD42023471797. RESULTS We included six RCTs with a total of 694 patients. HPSD was significantly associated with a decreased total procedure time (MD: -22.88 with 95% CI [-36.13, -9.63], P = 0.0007), pulmonary vein isolation (PVI) time (MD: -19.73 with 95% CI [-23.93, -15.53], P < 0.00001), radiofrequency time (MD: -10.53 with 95% CI [-12.87, -8.19], P < 0.00001). However, there was no significant difference between HPSD and SPLD ablation with respect to the fluoroscopy time (MD: -0.69 with 95% CI [-2.00, 0.62], P = 0.30), the incidence of esophageal lesions (RR: 1.15 with 95% CI [0.43, 3.07], P = 0.77), and the incidence of first pass isolation (RR: 0.98 with 95% CI [0.88, 1.08], P = 0.65). CONCLUSION HPSD ablation was significantly associated with decreased total procedure time, PVI time, and radiofrequency time compared with SPLD ablation. On the contrary, SPLD ablation was significantly associated with low maximum temperature.

Abstract
1. The effectiveness of inactivated vaccines depends on selecting the suitable adjuvant for vaccine formulation. The potency of vaccines with low antigen content can be improved with the appropriate adjuvant. This could allow production of more doses and lower the production cost.2. This study evaluated the efficiency of vaccines prepared using oil extracted from natural sources including argan oil, almond oil, sesame seed oil, pumpkin oil, cactus oil and black seed oil as alternative adjuvants for improving the protection capacity of inactivated influenza virus vaccine as compared to commonly used mineral oils.3. Each vaccine formulation was evaluated for stability, safety and immunogenicity in chickens, as well as for reducing the viral shedding after challenge infection.4. The cactus, sesame and pumpkin seed oil-based vaccines were found to be potent and successfully induced the production of humoral immunity in vaccinated chickens.

Abstract
The pandemic Covid-19 affects mainly adult causing fatal illness specially who have co-morbidities. But as days pass by with increasing surveillances it's gradually obvious that this devastating disease also affects the children as well as neonates with greater number. The aim of study was to determine the Covid-19 in neonates. So, we can give proper emphasis on neonatal Covid-19. This cross-sectional study was conducted from April 2020 to September 2020 at Dhaka Shishu (Children) Hospital in Bangladesh. Neonates with suspected Covid-19 were tested for SARS-CoV-2 by RT- PCR. Newborn who had suspected or confirmed COVID-19 mother, exposed to relatives infected with Covid-19, related with cluster outbreak or with abnormal clinical courses such as respiratory distress, not responded to conventional treatment and also abnormal chest x-ray was selected for Covid-19 test. Data regarding gestational age, birth weight, gender, positive cases and other findings were collected and analyzed. Statistics analysis was done by SPSS version 26.0. Forty three cases were Covid-19 positive. Among them 28(65.1%) cases were male and 15(34.9%) female. Term was 39(90.6%) cases and preterm 4(9.4%). Twenty nine (67.5%) cases were belonged to medicine and 14(32.6%) surgical cases. Fourteen (32.5%) cases with Covid-19 lived in Dhaka and 29(67.5%) cases in outside of Dhaka. Eleven (25.5%) cases were positive for SARS -CoV-2 by RT- PCR within 3 days, among them 5 (11.6%) cases were within 24 hours of age. Nine (20.9%) and 23(53.5%) cases were test positive at day 4-7 and 8-28 days respectively. The main symptoms at admission were respiratory difficulty (12/43, 27.9%), fever (8/43, 18.6%), convulsion (8/43, 18.6%) and reluctance to feed (7/43, 16.6%). In neonate two or more diseases coexist in same cases. Sepsis was present in 20 (46.5%) cases with COVID-19. Perinatal asphyxia was present in 10(23.3%) and pneumonia in 8 (18.6%) cases. In laboratory findings low Hb% was present in 2/43(4.7%) cases, leukopenia in 4/43(9.3%), leukocytosis in 2/43(4.7%) and thrombocytopenia in 5/43(11.6%). Elevated CRP was present in 14/29 (32.6%) cases, hypernatremia in 10/33 (30.3%), hyponatremia in 1/33(3%), increased serum creatinine in 10/18(55.6%), and prolonged PT, aPTT in 2/2(100%). Hyperglycaemia was found in 1/15(6.7%) cases and hypoglycaemia in 2/15(13.3%). No organism was found in blood C/S. In chest X-ray, one showed patchy opacities in right lower lobe, another showed bilateral ground-glass opacity and third one revealed few patchy opacities in the right perihilar region. Among 43 cases 21(48.9%) were discharged with advice, 12(27.9%) cases referred to Covid-19 designated hospital, 2(4.7%) cases LAMA (Leave against medical advice) and 8(18.6%) cases died including one surgical case. A good number (43) of Covid-19 cases were found in this study. In neonates the clinical features could not be differentiated properly between Covid-19 or associated diseases unlike children and adult. The neonate may be a source of transmission of this disease. So, we should give proper emphasis on test, tracing and management of neonatal Covid-19.

Abstract
Nephrotic syndrome is the most common glomerular disease affecting children. Hypothyroidism is one of the most important complications which occur due to urinary loss of protein bound thyroid hormones, such as thyroxin binding globulin, transthyretin and albumin. This cross sectional study was conducted in the Department of Pediatric, Mymensingh Medical College Hospital (MMCH), Bangladesh from February 2018 to October 2019. This study was carried out to find out the thyroid profile in children with nephrotic syndrome and compared with thyroid profile of other acute illness in children. Total 122 children aged 2-12 years, further subdivided into Group A (n=61) suffering from nephrotic syndrome (1st attack, infrequent relapse) and Group B (n=61) other disease like viral fever, pneumonia, bronchiolitis, diarrhoea, UTI. Demographic details of patients and their relevant clinical details were obtained by an interviewer administered questionnaire. Blood for free T4, TSH were taken and compared between both groups. The mean FT4 values in Group A and Group B were 16.09±22.32fmol/ml and 68.22±11.65fmol/ml respectively, whereas the TSH level was significantly higher in Group A than controls (5.42±1.04 vs. 3.53±1.44). The T4 levels in nephrotic syndrome (Group A) patients were low. Analysis was done by using SPSS 22.0 version for windows software. Continuous and catagorical parameters were compared by unpaired 't' test and Chi-Square test. A p-value of 0.05 was considered significant. Hypothyroidism was found more in younger children i.e. age less than 6 years. This study concluded that children with nephrotic syndrome have a state of hypothyroidism.

Abstract
Hyponatremia is the most common electrolyte imbalance seen in clinical practice and a common laboratory findings in children with community acquired pneumonia. This study aimed to find out relationship between clinical profile, severity and outcome of community acquired pneumonia with hyponatremia in children aged 2-60 months. This descriptive cross-sectional study was done in pediatrics department of Mymensingh Medical College Hospital, Bangladesh. Study period was 6 month from November 2016 to April 2017. Data were collected from 2 months to 60 months old children who fulfill the selection criteria. In this study sampling technique was purposive. Detailed history was taken, and meticulous examinations and relevant investigations were performed. 100 patients with community acquired pneumonia were enrolled, 34.0% patient had hyponatremia and 66.0% patients had no hyponatremia. Hyponatremia is more marked (45.5%) in severe pneumonia followed by moderate pneumonia (33.3%) and no hyponatremia found in mild pneumonia. Mean temperature, respiratory rate, heart rate, head nodding, nasal flaring, grunting, stridor, cyanosis, convulsion, feeding problem, Poor air entry were significantly higher in patient of pneumonia with hyponatremia when compared to patient of pneumonia without hyponatremia. Mean duration of symptoms and mean duration of hospital stay were also significantly higher in patient of pneumonia with hyponatremia. The mean serum sodium concentration was 132.18±1.51mmol/L in hyponatremic patients and 137.91±1.94mmol/L in normonatremic patients. Mean values of total leucocyte count, ESR, and C-reactive protein were significantly higher in patient of pneumonia with hyponatremia. Serum hemoglobin was significantly lower in hyponatremic patients than normonatremic patients. Maximum (55.9%) patients of community acquired pneumonia (CAP) with hyponatremia had patchy opacity, 26.5% had consolidation, 11.8% had interstitial opacity and 5.9% had pneumatocele. All the patients were treated with appropriate antibiotics and fluid and discharged after complete recovery without any complication. There was no death in the study population. From this study we can conclude that, hyponatremia is directly related with the severity of community acquired pneumonia (CAP). The intensity of clinical profile and investigation findings are also directly related with the severity of pneumonia.

Abstract
The present study was conducted to investigate the antimicrobial potential of essential oils of Curcuma longa and Syzygium aromaticum against multidrug-resistant pathogenic bacteria. Four identified bacterial isolates including Methicillin-resistant Staphylococcus aureus (MRSA), Escherichia coli, Klebsiella pneumoniae, and Acinetobacter baumannii were selected and their antibiotic sensitivity was checked by disc diffusion assay. C. longa and S. aromaticum were subjected to steam distillation to obtain their essential oils. The crude essential oils were fractioned by employing column chromatography. Crude essential oils and their fractions were evaluated for their antibacterial activity by agar well diffusion assay and minimum inhibitory concentrations were calculated. All the selected bacterial isolates showed resistance to three or more than three antibiotic groups and were declared as multidrugresistant (MDRs). Crude essential oils of C. longa and S. aromaticum exhibited antimicrobial activity against all selected isolates but S. aromaticum activity was better than the C. longa with a maximum 19.3±1.50 mm zone of inhibition against A. baumannii at 1.04 µL/mL MIC. GC/MS analysis revealed the abundance of components including eugenol, eugenyl acetate, b- caryophyllene, and a- Humulene in both crude oil and fractions of S. aromaticum. While the main components of C. longa essential oil were Ar-tumerone, a-tumerone, b- Tumerone, I-Phellandrene, a-zingibirene, b- sesquiphellandrene, and p- Cymene. This study highlights that plant-based essential oils could be a promising alternative to antibiotics for which pathogens have developed resistance. C. longa and S. aromaticum carry compounds that have antimicrobial potential against multiple drug-resistant bacteria including MRSA. E. coli, K. pneumoniae and A. baumannii.

Abstract
The persistent evolution of drug-resistant influenza strains represents a global concern. The innovation of new treatment approaches through drug screening strategies and investigating the antiviral potential of bioactive natural-based chemicals may address the issue. Herein, we screened the anti-influenza efficacy of some biologically active indole and β-carboline (βC) indole alkaloids against two different influenza A viruses (IAV) with varied host range ranges; seasonal influenza A/Egypt/NRC098/2019(H1N1) and avian influenza A/chicken/Egypt/N12640A/2016(H5N1). All compounds were first assessed for their half-maximal cytotoxic concentration (CC50) in MDCK cells and half-maximal inhibitory concentrations (IC50) against influenza A/H5N1. Intriguingly, Strychnine sulfate, Harmalol, Harmane, and Harmaline showed robust anti-H5N1 activities with IC50 values of 11.85, 0.02, 0.023, and 3.42 µg/ml, respectively, as compared to zanamivir and amantadine as control drugs (IC50 = 0.079 µg/ml and 17.59 µg/ml, respectively). The efficacy of the predefined phytochemicals was further confirmed against influenza A/H1N1 and they displayed potent anti-H1N1 activities compared to reference drugs. Based on SI values, the highly promising compounds were then evaluated for antiviral efficacy through plaque reduction assay and consistently they revealed high viral inhibition percentages at non-toxic concentrations. By studying the modes of antiviral action, Harmane and Harmalol could suppress viral infection via interfering mainly with the viral replication of the influenza A/H5N1 virus, whilst Harmaline exhibited a viricidal effect against the influenza A/H5N1 virus. Whereas, Strychnine sulfate elucidated its anti-influenza potency by interfering with viral adsorption into MDCK cells. Consistently, chemoinformatic studies showed that all studied phytochemicals illustrated HB formations with essential peptide cleft through the NH of indole moiety. Among active alkaloids, harmalol displayed the best lipophilicity metrics including ligand efficiency (LE) and ligand lipophilic efficiency (LLE) for both viruses. Compounds geometry and their ability to participate in HB formation are very crucial.

Abstract
Thirty puppies were randomly divided in to 3 groups for comparative evaluation of two commercial CPV vaccines. Each group was further subdivided in to < 6 months and < 3 months -old puppies and either vaccinated with a monovalent vaccine: Primodog, a combination vaccine: Duramune or maintained as a non-vaccinated control. Humoral immune response was determined by Hemagglutination Inhibition (HAI) on 21 and 35 -days after vaccination. The geometric mean titer (GMT) induced by Duramune, 21 and 35 -days post-vaccination was GMT 73.3 and 137.2, respectively. Comparatively, Primodog demonstrated higher GMT on 21 and 35 -days after vaccination: 97.0 and 168.9, respectively. The older puppies (< 6 months old) demonstrated higher seroconversion to both vaccines.

Abstract
Background Discontinuation of the most effective methods of contraception such as Implanon has now become a worldwide problem, which is significantly associated with mistimed and unwanted pregnancies and unsafe abortion, leading to an increased risk of maternal and child mortality and morbidity. However, studies on factors associated with Implanon discontinuation in Ethiopia, particularly in the area under this study, are limited. Therefore, this study aims to identify the determinants of Implanon discontinuation among women who used Implanon at Debre Berhan town public health institutions. Methods and materials A facility-based unmatched case-control study was conducted among 312 study participants (78 cases and 234 controls) from February 1, 2021, to April 30, 2021. The study participants were selected by using a systematic random sampling method for controls, and cases were selected consecutively until the required sample size was reached, during the data collection period. The data were collected by using a structured face-to-face interviewer-administered questionnaire and entered into Epidata version 4.6 and transferred to SPSS version 25 for analysis. Variables with a p-value of <0.25 in the bivariable analysis were entered into the multivariable logistic regression model. In the final model variables, a p-value of <0.05 was considered statistically significant at a 95% confidence interval (CI) and the strength of association was measured using an adjusted odds ratio (AOR). Results In this study, the determinants of Implanon discontinuation were the following: women who had no formal education (AOR: 3.57; 95% CI, 1.62-7.87), who had no children (AOR: 2.8; 95% CI, 1.50-5.17), who had no counseling about side effects (AOR: 2.43;95% CI, 1.30-4.55), who had no discussion with their partner (AOR: 2.7; 95% CI, 1.34-5.46), who had no follow-up appointment (AOR:2.81; 95% CI, 1.54-5.12), and who had side effects (AOR:1.91; 95% CI, 1.13-3.53). Conclusion and Recommendations Women's educational status, having no children during the insertion of Implanon, received no counseling about the side effects of insertion, no follow-up appointment, experiencing side effects, and no discussion with a partner were determinants of Implanon discontinuation. Hence, healthcare providers and other health sector stakeholders should provide and strengthen pre-insertion counseling, and follow-up appointments to increase the retention rates of Implanon.

Abstract
LaIr3Ga2 is a kagome superconductor with a superconducting temperature (Tc) of 5.16 K. Here, we present the physical properties of the LaIr3Ga2 kagome superconductor computed via the DFT method wherein six different exchange-correlation functionals were used. The lattice parameters obtained using different functionals are reasonable, with a slight variation compared to experimental values. The bonding nature was explored. The elastic constants (Cij), moduli (B, G, Y), and Vickers hardness (Hv) were computed to disclose the mechanical behavior. The Hv values were estimated to be 2.56-3.16 GPa using various exchange-correlation functionals, indicating the softness of the kagome material. The Pugh ratio, Poisson's ratio, and Cauchy pressure revealed the ductile nature. In addition, mechanical stability was ensured based on the estimated elastic constants. The anisotropic mechanical behavior was confirmed via different anisotropic indices. The Debye temperature (ΘD), melting temperature (Tm), and minimum thermal conductivity (kmin) were calculated to characterize the thermal properties and predict the potential of LaIr3Ga2 as a thermal barrier coating material. The electronic density of states was investigated in detail. The McMillan equation was used to estimate Tc, and the electron-phonon coupling constant (λ) was calculated to explore the superconducting nature. The important optical constants were also calculated to explore its possible optoelectronic applications. The values of reflectivity in the IR-visible region are about 62% to 80%, indicating that the compound under study is suitable as a coating to reduce solar heating. The obtained parameters were compared with previously reported parameters, where available.

Abstract
Background
Bicuspid AV disease has been excluded from the seminal trials evaluating transcatheter heart valve (THV) placement in severe aortic stenosis. Although registry data has shown good results overall, case selection likely involves more challenging anatomical subsets being treated either surgically or medically in this very heterogenous condition. Conventional annular placement, as well as high annular placement in tapered anatomies remain the commonest deployment techniques. We reasoned that marked supra-annular placement with the mid-portion of the SAPIEN 3 Ultra (S3U) valve sealing skirt placed at the narrowest opening point at commissural level could be an alternative strategy allowing treatment of additional patient groups. This proposed technique takes advantage of elliptical expansion at commissural level with more circular expansion above and below this point to prevent embolisation, as well as sealing skirt positioning at the narrowest opening point to prevent paravalvular leak.
Aims
We examined the feasibility of marked supra-annular placement of the balloon-expandable S3U prosthesis with the mid-point of the sealing skirt placed at commissural level in patients with severe bicuspid aortic valve stenosis and relative contra-indications to annular placement.
Methods
We assessed patients with severe bicuspid aortic stenosis undergoing TAVI at our centre over a 9-month period and identified those with relative contra-indications to conventional annular placement. These included: (i) excessive annular size (ii) severe leaflet and raphe calcification with risk of rupture into the right ventricle (iii) excessive leaflet length with potential leaflet overhang. CT imaging was used to define the narrowest opening location at commissural level, typically 10–15mm supra-annular. The diameter at this level was used to select THV size. Calculations were made to approximate the mid skirt level to this supra-annular position. In most cases this involved supra-annular positioning with the lower THV border 5–8mm supra-annular. This was achieved in most cases by aligning the unexpanded border with the annulus.
Results
Out of 9 patients with biscupid AV, 4 had relative contra-indications for annular placement. In all 4 cases, excellent valvular expansion with only minimal paravaulvar leak was achieved with placement of the S3U prosthesis at 5–7mm above the annulus and with supra-annular sealing at commissural level. Annular dimensions of 35.5mm and 31.5mm were successfully treated with 29mm and 26mm valves due to significant tapering at commissural level in 2 patients. There were no procedural complications, incidences of AV blocks or valve embolisation.
Conclusion
As a proof of concept, we have demonstrated excellent outcomes with marked supra-annular TAVI placement in patients with severe bicuspid AV stenosis and anatomy unfavourable for conventional annular placement. This is the first description of this completely novel deployment technique.

Abstract
Subtrochanteric femoral fractures are one of the common fractures encountered in today's Orthopaedic practice. High stress leads implant failure and produce varus collapse. From the perspective of biomechanics, intramedullary fixation has unique advantage which can better distribute stress and acting load-sharing implants. Biomechanically proximal wide canal and short segment provide less optimal fixation by conventional intramedullary nails. Intramedullary nail by Surgical Implant Generation Network (SIGN) has proximal interlocking that gain purchase through femoral neck and provide improved stability for proximal part. The aim of this study was to evaluate the functional outcome of subtrochanteric fractures fixation by intramedullary interlocking SIGN nail. This prospective study was conducted from July 2016 to June 2018 at National Institute of Traumatology and Orthopaedic Rehabilitation (NITOR) through non randomized purposive sampling. Total 31 patients, aged above 18 years irrespective of sex with closed subtrochanteric fractures were included. Patients with pathological fracture, multiple injuries were excluded from the study. The mean age of the patients was 42.61±19.59 years with range 18-80 years. Most common fractures were Seinsheimer type III (51.6%) and average follows up 42.39 weeks (24-48 weeks). Union rate 93.55% with delayed union 6.45% and no nonunion. Functionally most of patient started early partial (77.42%) and full (64.52%) weight bearing with 61.29% have full knee ROM and 83.9% without limb shortening. Maximum patients regained walking (83.87%) and squatting (90.32%) and return to preinjury state (80.65%) of activities. Evaluation of outcome by Modified Harris Hip Score showed excellent (70.97%), good (22.58%), fair (3.23%) and poor (3.23%) thus satisfactory outcome were 93.55%. This study concludes that intramedullary interlocking SIGN nail is a safe and reliable implant for the treatment of subtrochanteric fractures with excellent functional outcome.

Abstract
Treatment of sub-trochanteric femoral fractures is a challenge to orthopaedic surgeons. High incidence of fixation failure and nonunion is due to thick cortical bone deserves special consideration of surgical treatment. Intramedullary nail by Surgical Implant Generation Network (SIGN) shows promising results in comparison to conventional fixation method because of its better strength, accuracy and surprisingly better results in infection and non-union. The aim of this study was to assess the rate and time taken for union of fractures by SIGN nail and determine peri-operative parameters. This prospective study was conducted from July 2016 to June 2018 at National Institute of Traumatology and Orthopaedic rehabilitation (NITOR) through non randomized purposive sampling. Total 31 patients, aged above 18 years irrespective of sex with closed subtrochanteric fractures were included. Patients with pathological fracture, multiple injuries were excluded from the study. Union status evaluated by Radiographic Union Score for Tibial (RUST) fracture where antero-posterior and lateral radiographs (X-ray) based assessment of healing of the four cortices done. The individual cortical scores were added to give a total score 4 being the minimum indicating fracture is definitely not healed and 12 being the maximum score indicating that the fracture is definitely healed. The mean age of the patients was 42.61±19.59 years with range 18-80 years. Majority of patients were male (68%) and most of injury (68%) due to road traffic accident with common fracture were Seinsheimer type III (51.6%). Average hospital stay period was 16.39 days and average follows up 42.39 weeks (24-48 weeks). Time taken for union was 14.16 weeks (11-28 weeks). According to RUST scores fracture union rate 93.55% with delayed union 6.45% and no nonunion. There was one patient with superficial wound infection, one unaccepted shortening and with no implant failure. This study concludes that intramedullary interlocking SIGN nail is a safe and reliable implant for the treatment of subtrochanteric femoral fractures.

Abstract
Background: The rapid worldwide spread of the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) or COVID-19 pandemic from its epicentre; Wuhan has led to an epidemiological breakdown. Egypt reported its first COVID-19 case on Feb 14, 20202,3. Thereafter, Egypt scaled-up preventive measures, with a partial lockdown starting on March 25. Several therapeutic agents along with Convalescent Plasma Transfusion are under investigation and data from Convalescent Plasma Transfusions (CPT) have been receiving a lot of attention, after Emergency approvals from the Food and Drug Administration (FDA) suggesting that it may provide a clinical effect in the treatment of SARS-COV-2
Importance: Early and effective treatment of COVID-19 is vital for control of SARS-CoV-2 infection
Methods:
-Designs: An interventional, single-arm, non-randomized clinical trial conducted in Egypt from April 15 to July 21, 2020.
-Settings: This was a multi-centre study conducted in 3 hospitals in Egypt.
-Participants: a total of 94 COVID-19 laboratory-confirmed patients using qRT-PCR were enrolled in the study.
-Intervention: All patients were administered with two plasma units (each unit is 200cc). The volume of donated plasma was 800cc.
-Main Outcome and Measures: Primary measure was the degree of clinical improvement among the COVID-19 patients who received CPT within seven days
Results: A total of 94 patients were enrolled who received CPT either within seven days or after seven days of hospitalization. 82 were severely ill, 12 were critically ill. The average age remained 58 years (±SD 15.1 years). Male were 69% and 49% patients got cured while 51% died with CFR 51%. 75% deaths were above 45years of age. The symptoms were dyspnoea (55%), fever (52%), cough (46%), and loss of taste and smell (21%), and cyanosis (15%). The most common co-morbidities among the <40 years remained Diabetes Mellitus (21%) and Asthma (14%). Among 40-60 years Hypertension (56%), Diabetes Mellitus (39%) and among >60 years age group Hypertension (57%) and Chronic Heart Disease (24%) were reported. CPT within seven days remained significant as compared with the CPT after seven days with the number of days to cure (p=0.007) and ICU stay (P=0.008) among severely ill cured cases.
Conclusions: Among patients with COVID-19 and severe or critical illness, the use of CPT along with routine standard therapy resulted in a statistically significant improvement when administered within seven days of hospital admission. However, plasma transfusion, irrespective of days to transfusion may not help treat critically ill patients. The overall mean time to cure in severely ill patients was 15 days if CPT provided within seven days with 65% cure rate.

Abstract
Although huge improvement in neonatal mortality reduction in last two decades in Bangladesh but it is still very high compare with many other countries. High neonatal mortality also significantly contribute deaths among the under five children. Neonatal mortality reflects a nation's socio-economic status, efficiency and effectiveness of health care services. This was cross sectional study. The objective of this study was to analyse the diseases pattern and outcome of the neonates admitted in the newly established SCANU (Special care neonatal unit) of 250 bedded General Hospital of Tangail district, Bangladesh. Study period was one year from January 2017 to December 2017. Information from medical records of the SCANU was analysed. During the study period 1,379 neonates were admitted in the SCANU. The ratio between male and female was 1.5:1, 61% of the neonates admitted at first day of life. The reasons for admissions in SCANU were 31% of preterm and low birth weight, 23%birth asphyxia, 13% neonatal sepsis, 9% transient tachypnea of newborn, 5% congenital anomalies and 4% neonatal jaundice. Out of all neonates survival rate was 56% (779), while 25% (349) ended with fatality, 9% (122) were referred to tertiary level hospital and 10% (129) were left the hospital against medical advice. Among the fatal cases 63% died in first 24 hours and 88% in first week of life. Data shows that 47% deaths were due to preterm and low birth weight with its complication, other significant causes were birth asphyxia (30%), septicemia (16%) and congenital anomalies were (6%). Preterm and low birth weight, neonatal sepsis, birth asphyxia, transient tachypnea of newborn; congenital anomalies were the main reasons for admission in SCANU. Prematurity and its complication, birth asphyxia and neonatal sepsis as the major contributors to the neonatal mortality. The study findings will help researchers and policy makers to initiate further research and interventions to reduce fatality among the neonates in the SCANU.

Abstract
Probiotics are live microorganisms that, when administered in adequate amount helps in reducing the duration of diarrhoea. Objective of this double blind randomized controlled clinical trial was to assess the efficacy of probiotics in treatment of acute rotavirus & non rotavirus watery diarrhoea among children aged 6 months to 2 years admitted at diarrhoea corner of Paediatrics Department of Mymensingh Medical College Hospital from October 2017 to May 2019. It was a double blind randomized controlled clinical trial. Total 500 sample were divided into Group A=ORS, zinc plus placebo (n=250) and Group B=ORS, zinc plus probiotics (n=250). Both Group A and Group B consisted of children presented with rotavirus and non-rotavirus diarrhoea. Placebo or probiotics were given once daily for 5 days which was prepared and coded by department of Pharmacology. Stool specimens were taken to Microbiology Department of MMCH for rotavirus detection. Rotavirus was detected by Polyacrylamide gel electrophoresis (PAGE). Data was analyzed by computer using SPSS program version 23.0. A total of 500 children with acute watery diarrhoea were included. Among them 188 children were diagnosed as rotavirus positive. Among group A found 89 rotaviral and 161 non rotaviral diarrhoea patients. Among group B found 99 rotaviral and 151 non rotaviral diarrhoea patients. Baseline characteristics were similar in both groups. The duration of diarrhoea, hospital stay, and fever was significantly lesser in probiotics group when compared with control (p<0.001). But duration of vomiting did not reduce significantly in probiotics group. Frequency of stools reduced significantly in probiotics group.

Abstract
Hepatitis B virus infection is an important cause of liver disease. Hepatitis B Virus may present with varying degree of severity. In older children, 5-10% cases leading to chronic liver disease, cirrhosis and hepatocellular carcinoma. This descriptive cross sectional study was done to assess the prevalence of Hepatitis B Virus infection among hospitalized children with liver disease in pediatric department of Mymensingh Medical College Hospital, Bangladesh from December 2015 to October 2016. All the children of both sexes having age between six months to twelve years admitted in the pediatric ward with acute or chronic liver disease were included in this study by purposive sampling. A written consent was obtained from legal guardian of children before inclusion. Ethical clearance was obtained from competent authority. A detailed history was taken from parents in each case according to pre-designed questionnaire about demography of the patients and the risk factors of the liver disease. A thorough clinical examination and available relevant investigations like serological testing for HBV infection was done in all patients. We had figure out the seropositivity of HBV among patients having liver disease by doing HBsAg and Anti-HBc IgM. Progress of the patient was monitored by daily clinical examinations and by investigating HBsAg and Anti-HBc IgM. Finally data analysis was done by SPSS version 21.0. Among total 100 patients most (44%) patients were in 7-10 years old and most (62%) of the participants were male. Acute liver disease was 58% cases and chronic liver disease was 42% cases. HBsAg was positive in 1 case among acute liver disease and 5 cases among chronic cases. Total 6 (six) patients were found positive for HBsAg. Anti HBc IgM was positive in 4 patients among acute liver disease. Among these Anti HBc IgM positive (4) patients only one had both HBsAg and Anti HBc IgM positive. So, four patients were confirming suffered from acute viral hepatitis because they had anti HBc IgM positive. On the contrary 5 patients suffered from chronic hepatitis by hepatitis B because they were only HBsAg positive. So, in this study 9 patients (9%) were confirming suffered from HBV infection. Possible transmission factors of hepatitis B were history of (H/O) blood transfusion/trauma/parenteral injection, H/O umbilical sepsis, H/O maternal illness/infection during pregnancy. HBV still is a major cause of morbidity. All the children with liver disease should be routinely tested for HBV.

Abstract
Obesity is now recognized as a major cause of morbidity and mortality throughout the world. The relative percentage of change is higher in developing countries. Childhood obesity has become a serious public health emerging problem because of its strong association with adulthood obesity and related adverse health consequences. The main objective of the study was to find out the status of overweight and obesity among primary school children of Mymensingh municipal area. This cross sectional descriptive study was carried out among primary school children of Mymensingh municipal area from September 2016 to February 2018. Total 1450 students were enrolled from 6 schools. Schools were selected by random lottery method. Data was collected in predesigned case record forms by investigator with the help of students, teachers and parents. Anthropometry was measured by principal investigator. Body mass index (BMI) was calculated and plotted by using Center for disease control (CDC) BMI growth charts for age and sex. Children were categorized as obese, overweight, normal and underweight. Data analysis was done by computer software SPSS version 20.0. Mean age of children was 9.0±1.124 years. There was 47.4% male and 52.6% female. Among the 1450 children 18.6% obese, 17.5% overweight, 53.5% normal and 10.4% underweight. So, total 36.1% children had BMI above normal limit. Obesity was found more common among male children (p<0.001). Obesity and overweight was significantly associated with fast food consumption (p<0.001), playing computer and mobile games (p<0.001), watching TV (p<0.001), higher parent's education (p<0.001), higher parent's income (p<0.001), service holder father (p<0.001), family history of overweight or obesity (p<0.001), single child in family (p<0.001) and increased birth weight (p<0.001). A large number of primary school children in Mymensingh municipal area were overweight and obese. Childhood obesity and overweight varies from school to school. Childhood obesity and overweight is an emerging and growing health issue in municipal area.

Abstract
Cyclin-Dependent Kinases (CDKs) are a family of enzymes that, along with their Cyclin
partners, play a crucial role in cell cycle regulation at many biological functions such as proliferation,
differentiation, DNA repair, and apoptosis. Thus, they are tightly regulated by a number of inhibitory
and activating enzymes. Deregulation of these kinases’ activity either by amplification,
overexpression or mutation of CDKs or Cyclins leads to uncontrolled proliferation of cancer cells.
Hyperactivity of these kinases has been reported in a wide variety of human cancers. Hence, CDKs
have been established as one of the most attractive pharmacological targets in the development of
promising anticancer drugs. The elucidated structural features and the well-characterized molecular
mechanisms of CDKs have been the guide in designing inhibitors to these kinases. Yet, they remain
a challenging therapeutic class as they share conserved structure similarity in their active site.
Several inhibitors have been discovered from natural sources or identified through high throughput
screening and rational drug design approaches. Most of these inhibitors target the ATP binding
pocket, therefore, they suffer from a number of limitations. Here, a growing number of ATP noncompetitive
peptides and small molecules has been reported.

Abstract
Since the emergence of the SARS-CoV-2 pandemic in 2019, it has remained a significant global threat, especially with the newly evolved variants. Despite the presence of different COVID-19 vaccines, the discovery of proper antiviral therapeutics is an urgent necessity. Nature is considered as a historical trove for drug discovery, especially in global crises. During our efforts to discover potential anti-SARS CoV-2 natural therapeutics, screening our in-house natural products and plant crude extracts library led to the identification of C. benedictus extract as a promising candidate. To find out the main chemical constituents responsible for the extract's antiviral activity, we utilized recently reported SARS CoV-2 structural information in comprehensive in silico investigations (e.g., ensemble docking and physics-based molecular modeling). As a result, we constructed protein-protein and protein-compound interaction networks that suggest cnicin as the most promising anti-SARS CoV-2 hit that might inhibit viral multi-targets. The subsequent in vitro validation confirmed that cnicin could impede the viral replication of SARS CoV-2 in a dose-dependent manner, with an IC50 value of 1.18 µg/mL. Furthermore, drug-like property calculations strongly recommended cnicin for further in vivo and clinical experiments. The present investigation highlighted natural products as crucial and readily available sources for developing antiviral therapeutics. Additionally, it revealed the key contributions of bioinformatics and computer-aided modeling tools in accelerating the discovery rate of potential therapeutics, particularly in emergency times like the current COVID-19 pandemic.

Abstract
A DFT study of the synthesized MAX phase Zr2SeC has been carried out for the first time to explore its physical properties for possible applications in many sectors. The studied properties are compared with prior known MAX phase Zr2SC. The structural parameters (lattice constants, volume, and atomic positions) are observed to be consistent with earlier results. The band structure and density of states (DOS) are used to explore the metallic conductivity, anisotropic electrical conductivity, and the dominant role of Zr-d states to the electrical conductivity at the Fermi level. Analysis of the peaks in the DOS and charge density mapping (CDM) of Zr2SeC and Zr2SC revealed the possible variation of the mechanical properties and hardness among them. The mechanical stability has been checked using elastic constants. The values of the elastic constants, elastic moduli and hardness parameters of Zr2SeC are found to be lowered than those of Zr2SC. The anisotropic behavior of the mechanical properties has been studied and analyzed. Technologically important thermodynamic properties such as the thermal expansion coefficient (TEC), Debye temperature (Θ D), entropy (S), heat capacity at constant volume (C v), Grüneisen parameter (γ) along with volume (V) and Gibbs free energy (G) are investigated as a function of both temperature (from 0 to 1600 K) and pressure (from 0 to 50 GPa). Besides, the Θ D, minimum thermal conductivity (K min), melting point (T m), and γ have also been calculated at room temperature and found to be lowered for Zr2SeC compared to Zr2SC owing to their close relationship with the mechanical parameters. The value of the Θ D, K min, T m, and TEC suggest Zr2SeC as a thermal barrier coating material. The optical properties such as dielectric constant (real and imaginary part), refractive index, extinction coefficient, absorption coefficient, photoconductivity, reflectivity, and loss function of Zr2SeC are computed and analyzed to reveal its possible applications.

Abstract
In adults, distal humerus fractures are infrequent and frequently intra-articular. Customarily encompass both medial and lateral columns. Operative management gives constructive outcomes. The aim of this study was to evaluate clinical outcome in intra articular distal humerus fractures in adults treated by different hardware. This prospective study consists of 20 purposively selected patients with intra articular distal humerus fractures treated by surgical intervention with different hardware who were admitted to Mymensingh Medical College and Hospital, Bangladesh in between November 2016 to October 2018. Surgical approaches were standard dorsal with or without olecranon osteotomy. The mean age of the patients was 32.3 years, range between 18-55 years. The maximum patients i.e. 85% were between 18-45 years. Seventy percent (70%) of the cases admitted were due to Road traffic accident (RTA). Most of the patients were males 14(70%) with right upper limb was involved in 13(65%) cases. Mean Mayo Elbow Performance Score was 81.5 post-operatively. According to Mayo Elbow Performance (MEP) score clinical outcome was excellent in 20%, good in 50%, fair in 25% and poor in 10% of patients. Distal humerus fractures are censorious in nature. Proper anatomical articular reconstruction and stable fixation by surgical intervention helps in fruitful results.

Abstract
Infantile colic is a prevalent condition characterised by excessive crying with no effective treatment available. We aimed to evaluate the efficacy of Bifidobacterium breve CECT7263 and a combination of this and Lactobacillus fermentum CECT5716 versus simethicone in reducing the daily time spent crying in colicky infants. A multicentre randomised, open-label, parallel, controlled trial of 28 days was performed in 150 infants who were diagnosed with colic according to the Rome III criteria and who randomly received simethicone (80 mg/day; Simethicone group), B. breve CECT7263 (2×108 cfu/day, Bb group), or a combination of L. fermentum CECT5716 and B. breve CECT7263 (1×108 cfu/day per strain, Bb+Lf group). The main outcomes were minutes of crying per day and the percentage of reduction in daily crying from baseline. Data were analysed per intention to treat. All treatments significantly decreased the daily crying time at the end of the intervention (P-time <0.001). However, the infants in the Bb group had significantly decreased crying time from the first week of the study (P<0.05), whereas the Bb+Lf group and the simethicone group had significantly decreased crying time from the second week (P<0.05). The percentage of reduction in the minutes of crying from baseline in the Bb group was significantly higher than that in the Simethicone group every week of the intervention (-40.3 vs -27.6% at 1-week; -59.2 vs -43.2% at 2-weeks; -64.5 vs -53.5% at 3-week and -68.5 vs -59.5% at 4-weeks, P<0.05). Additionally, in the Bb group, infants had better night sleep, and parents reported a more positive mood at the end of the intervention. All the products used in the study were safe and well tolerated. In conclusion, the breastmilk-isolated probiotic strain B. breve CECT7263 is a safe and effective treatment for infantile colic, presenting an earlier and more robust effect than the reference prescribed drug, simethicone.

Abstract
The structural, electronic, mechanical and thermodynamic properties of (Ti1−xMox)2AlC (0 ≤ x ≤ 0.20) were explored using density functional theory. The obtained lattice constants agree well with the experimental values. The electronic band structure confirms the metallic nature. Strengthening of covalent bonds due to Mo substitution is confirmed from the study of band structure, electronic density of states and charge density mapping. The elastic constants satisfy the mechanical stability criteria. Strengthening of covalent bonds leads to enhanced mechanical properties. (Ti1−xMox)2AlC compounds are found to exhibit brittle behavior. The anisotropic nature of (Ti1−xMox)2AlC is revealed from the direction dependent Young's modulus, compressibility, shear modulus and Poisson's ratio as well as the shear anisotropic constants and the universal anisotropic factor. The Debye temperature, minimum thermal conductivity, Grüneisen parameter and melting temperature of (Ti1−xMox)2AlC have been calculated for different Mo contents. Our calculated values are compared with reported values, where available. The structural, electronic, mechanical and thermodynamic properties of (Ti1−xMox)2AlC (0 ≤ x ≤ 0.20) were explored using density functional theory.![]()

Abstract
Background: Systemic Lupus Erythematous (SLE) is a chronic systemic autoimmune disorder whose diagnosis depends on combination of multiple factors. Circulating lncRNAs could serve as diagnostic non-invasive biomarkers for SLE. We hypothesised that serum FAS-AS1 and PVT1 are new biomarkers for SLE that relate to clinical features and laboratory markers. Materials and Method: Measurement of serum FAS-AS1 & PVT1 by qRT-PCR, analysis of the association between two RNAs and the clinical data, activity index and laboratory markers by standard routine methods. Results: There was a significant relative increased serum FAS-AS1 (median (IQR) 2.19 (0.13-8.62) and a significant reduced PVT1 (median (IQR) 0.52 (0.01-7.55) in SLE patients compared to controls (P < 0.0001 for FAS-AS1 and = 0.007 for PVT1). Serum FAS-AS1 and PVT1 were positively correlated (r= 0.37, P = 0.001). Higher FAS-AS1 was significantly linked with nephritis (P = 0.011), positive anti-dsDNA (P= 0.01) and lower serum PVT1 was significantly associated with oral ulcers (P= 0.023), photosensitivity (P= 0.017), and neurological manifestations (P= 0.041). Serum PVT1 negatively correlated with age (r= -0.52, P< 0.0001) and ESR level (r= -0.29, P= 0.011) in SLE patients. No correlation between disease activity and serum FAS-AS1 or PVT1 was detected. Conclusions: Our study provides evidence that serum FAS-AS1 and PVT1 are new biomarkers for SLE.

Abstract
Acetabular fracture usually occurs as a result of high velocity injury and often affects the young and economically productive population. Previously, treatment of acetabular fracture was grossly inadequate and many patients were left with incapacitating pain, limitation of movement. Proper management should be given in our set-up to save lives and to minimize long term complications and related disabilities. This study was done to evaluate the outcome of open reduction and internal fixation of posterior wall fracture of acetabulum. This prospective observational study was carried out in Dhaka Medical College Hospital, Dhaka, Bangladesh from July 2016 to June 2018. Total twenty five cases were selected. Radiological and functional outcome were evaluated six months after surgery according to Matta radiographic criteria and Merle d Aubigne and Postel criteria respectively. Effect of age, gender, hip dislocation, displacement of fracture fragment, associated injury, reduction quality, trauma to surgery time, complication of operation on the functional outcome was evaluated. Age range was 18-60 years. The mean age was 38±11 years. Male 23 and female 2, male and female ratio was 11.5:1. Mean follow up 8.5±1.7 months, range 6-12 months. According to Matta radiographic criteria, 6 months after surgery, 10 patients had excellent, 10 patients had good, 3 patients had fair and 2 patients had poor radiological outcome. According to Merle d Aubigne and Postel criteria, 6 months after surgery, 11 patients had excellent, 10 patients had good, 3 patients had fair and 1 patient had poor functional outcome. Overall functional outcome of the study population revealed that 21 patients (84%) belonged to satisfactory (Excellent + Good) and 4 patients (16%) belonged to unsatisfactory (Fair + Poor) outcome. AVN (avascular necrosis) of femoral head had been occurred in two patients, post-operative wound infection had been occurred in two patients and myositis ossificans around hip joint had been occurred in two patients. Twenty (20) patients were achieved anatomic (0, 1mm) reduction, 3 patients were achieved imperfect (2, 3mm) reduction and 2 patients were achieved poor (>3mm) reduction. This study concludes that open reduction and internal fixation of posterior wall fracture of acetabulum is a satisfactory method of treatment.

Abstract
BACKGROUND Certain single nucleotide polymorphisms (SNPs) in genes such as PADI4 (coding for peptidyl arginine deiminase 4), PDCD1 (coding for programmed cell death 1), and CTLA4 (coding for cytotoxic T-lymphocyte-associated protein 4) are linked to rheumatoid arthritis (RA). However, links between SNPs rs2240340, rs10204525 and rs231775 in PADI4, PDCD1 and CTLA4 respectively, and juvenile idiopathic arthritis (JIA), the commonest type of childhood arthritis, are unclear. We aimed to determine whether any of these SNPs are associated with JIA, and to clinical indices disease activity score (JADAS 71) and functional disability score (CHAQ). METHODS We genotyped the three SNPs in 150 children with polyarticular JIA and 160 healthy children, recording standard health questionnaires, clinical features and laboratory markers. RESULTS The TT genotype of PADI4 rs2240340 (aOR/95%CI 2.64: 1.31-5.30, P = 0.006) and CT genotype of PDCD1 rs10204525 (aOR/95%CI 4.99: 2.98-8.36, P < 0.0001) were associated with JIA. The AG+GG genotype of CTLA4 rs231175 was modestly linked to disease activity (aOR/95%CI 2.44 (1.19-5.04), p = 0.015). PADI4 rs2240340 was linked to CHAQ score (genotypes p = 0.013, alleles p = 0.006), whilst PDCD1 rs10204525 was linked to anti-CCP antibodies (genotypes p = 0.004), RF (genotypes p = 0.01), and the CHAQ score (genotypes p = 0.005, alleles p = 0.013). CONCLUSIONS There are various roles for these SNPs in PADI4, CTLA4 and PDCD1 in the diagnosis and, potentially, in the management of JIA.

Abstract
Astroviruses belong to Astroviridae family which includes two main genera: Mamastroviruses that infect mammals, and Avastroviruses that infect avian hosts. Bats and wild birds are considered among the natural reservoirs for astroviruses. Infections in humans are associated with severe gastroenteritis, especially among children. We conducted surveillance for astroviruses in bats, wild birds, and humans in Egypt. Our results indicated relatively high prevalence of astroviruses in those hosts. Phylogenetic analysis revealed diversity of these viruses within hosts. Detected human viruses showed similarity with classic and variant human astroviruses, as well as similarity with animal-origin viruses. Viruses in bats were dispersed, with similarities to other bat viruses as well as other mammalian, including human, viruses. Wild bird viruses varied and were related to other avastroviruses, as well as human astroviruses. Our results indicate that astroviruses are common in bats, wild birds, and humans in Egypt, with a wide gene pool. Potential cross-species transmission may be occurring but should be verified by further surveillance and molecular studies.

Abstract
In spite of the recommendation for rescue antenatal corticosteroids (ACS), the optimal time interval between primary and rescue courses has not been clearly demonstrated. The aim of this retrospective study was to determine the effects of the interval between a single ACS (Dexamethasone) course and delivery on the incidence of respiratory distress syndrome (RDS) in neonates at Mymensingh Medical College Hospital Center from 1st January 2017 to 30th June 2017. Injection Dexamethasone 2 doses (12.5mg IM 12 hourly for 2 doses) or 4 doses (6mg IM every 12 hours for 4 doses) use to arrest preterm labor as well as to prevent RDS delivered beyond 48 hours after ACS administration between 24 and 34 weeks gestation. The risk of RDS was compared between patients who delivered within seven days (Group I) and 7-14 days (Group II) after ACS administration. We included 140 and 60 patients in Group I and Group II respectively. After adjusting for confounders, the ACS delivery interval was significantly associated with RDS in Group II (adjusted odds ratio 12.8, 95% confidence interval 1.31-164.7). A longer ACS delivery interval is associated with a higher risk of RDS. Thus, the use of a rescue course could be expected to reduce the incidence of RDS in patients beyond seven days after ACS administration who remain at risk for preterm delivery within seven days, especially in cases of placenta previa and/or women bearing a male fetus.

Abstract
Acute post-streptococcal glomerulonephritis (APSGN) is the commonest cause of acute glomerulonephritis (AGN), which usually present with gross hematuria, mild edema, oliguria, hypertension and varying degree of renal insufficiency. It is more common among the population of school going age where poverty, overcrowding and poor hygienic conditions are prevailing. This cross sectional observational study was aimed to know the socio-demographic variables, clinical profile and immediate outcome of AGN in hospitalized children and was conducted in the Pediatric department of Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from November 2014 to April 2015. A detailed history was taken from the parents in each case with a written questionnaire. A written consent was also taken from the guardian of the including patients and also permission was taken from the ethical committee of MMCH. Thorough clinical examination and available relevant investigations were done in all patients. Progresses of the patient were monitored by daily clinical examinations and also by investigations. Data were analyzed by statistical package for social science (SPSS) windows version 18. Results were verified by doing standard test for significance. Among total 60 cases male was 58.3% & female was 41.7%. The common age group of presentation was between 7-12 years (73%), peak age of incidence was 7-9 years. Most of them came from low socioeconomic status (83.3%), 63.3% from rural area with average 5-6 member's family size. Most of the parents were illiterate. History of (H/O) skin infection was present in 35(58.3%) patients, 15(25%) had H/O sore throat, 15% did not give any H/O infection before presentation. Average duration of gap between infection and appearance of clinical feature was 7-14 days in 73.40%and 15-21 days was in 45.7% in case of sore throat & skin infection respectively. Almost all (95%) patients presented with puffiness of face, others presented with scanty micturition, gross hematuria, respiratory distress, fever, convulsion and altered sensorium. Edema (75%), hypertension (88.3%), pallor (38%), tachypnea (25%), tachycardia (26.7%) were the important clinical findings. Microscopic hematuria was present among 96.66% patients; low complement level was found in 85% cases. There is significant association between low socioeconomic statuses with more hospital stay. Only one patient died due to heart failure and 98.3% patient had complete recovery. Results of this study conclude that most of the patients came from rural illiterate family with low socioeconomic background. Skin infection is the commonest cause of acute glomerulonephritis. Edema, scanty micturation, hematuria and hypertension are the common mode of presentation. Heart failure and hypertensive encephalopathy are the common complication of AGN. Immediate prognosis of AGN was excellent.

Abstract
Among nurses due to inadequate pain management knowledge and practice skills, children's pain is often under treated. This study aimed to examine the level of knowledge and practice on pediatric pain management among nurses in Bangladesh. This was a descriptive survey study involving total 150 clinical pediatric nurses from two Medical College Hospital and a University hospital in Bangladesh. The data collection tool consisted of demographic data form, 32-items nurses' knowledge. There were 32 true and false questions related to nurses' knowledge on pediatric pain management in Bangladesh. The response formats to each item for correct answer was 1 and incorrect answer 0. The total scores were categorized into three levels including low (0-20), moderate (21-23) and high (24 and above). The data collection tool consisted of demographic data form, 19-item practice related questionnaire on pediatric pain management. Nurses' practice on pediatric pain management contained 19 items with 5-points Likert's scale ranging from 1=Never practice to 5=constantly practice. For each item, a score of 5 was accorded for constantly and 1 for never. The score ranged from 19-95. The total scores were categorized into three levels including low (19-38), moderate (39-76) and high (77-95). The results demonstrated that most of the nurses' knowledge score on pediatric pain management was at moderate level (mean=21.50, SD=2.35). Nurses' practice on pediatric pain management was also at moderate level (mean=75.45, SD=8.24). The relationship between nurses' knowledge and practice was not significant. In addition, nurses' knowledge and practice with demographic variables; there was significant relationship between nurse's knowledge and existence of pain management protocol, nurses' practice and their current position in unit and with reading nursing journal. This study showed moderate level of knowledge and practice indicating that they need to be enhanced the knowledge and practice skills in pediatric pain management.

Abstract
Perinatal asphyxia is a major cause of neonatal mortality and morbidity in developing countries. A significant portion of patient with perinatal asphyxia is admitted with complications. Cerebral complications are the most devastating and the child may be left with lifelong neurological impairment. Therefore, the high index of suspicion, prompt recognition and thorough understanding of common sonographic abnormalities are necessary to ensure timely intervention, management and counseling. A hospital based case control study was conducted in the neonatal unit of Mymensingh Medical College Hospital, Mymensingh, Bangladesh. Study period was six months (June 2012 to December 2012). This study was done to compare the ultra sonogram of brain findings of admitted asphyxiated babies with admitted non-asphyxiated babies. A total of 30 asphyxiated (case) and another 30 non-asphyxiated (control) neonate of this department were enrolled in the study. Necessary information was collected by taking detailed history, clinical examination and also close follow up of the neonates according to pre-designed questionnaire. The main outcome variable was abnormality in cranial ultrasound. Among case group (30 neonates), ultrasonogram of brain findings were abnormal in 9(30.0%) cases. Among them most common was ventricular dilatation 5(16.6%), followed by Intraventricular hemorrhage (IVH) 1(3.0%), intracranial hemorrhage 1(3.0%), HIE 1(3.0%) and cerebral edema in 1(3.0%) cases. On the contrarary, among asphyxiated control group all 30 cases had normal ultra sonogram of brain. In case group 22 babies had normal birth weight and 08 had low birth weight. Among the 22 normal birth weight neonates in case group total 6(27.2%) cases had abnormal ultra sonogram findings. Among normal birth weight cases 3(13.6%) had ventricular dilatation, 1(4.5%) Intracranial hemorrhage (ICH), 1(4.5%) HIE, 1(4.5%) cerebral edema. Among 08 low birth weight neonates in case group total 3(37.5%) cases had abnormal ultrasonogram of brain finding. Among low birth weight cases 2(25%) had ventricular dilatation, 1(12.5%) IVH. Ultrasonogram brain findings difference between two groups was statistically significant. Abnormal findings were also common in low birth weight babies than normal birth weight babies. So, early detection of abnormal brain changes can help us for proper management and counseling.

Abstract
Dogs can act as a reservoir of canine leishmaniasis disease, which is caused by Leishmania species. The study aimed to identify and document the genotype of cutaneous leishmaniasis (CL) in the stray dogs in Riyadh Province using kinetoplast DNA (kDNA) as a target gene by using nested polymerase chain reaction (nPCR). This cross-sectional investigation was conducted over the course of two years, from March 2016 to July 2018, in different districts of Riyadh Province, Saudi Arabia. A total of 237 dogs were examined, only 18 of the dogs were suspected clinically of cutaneous leishmaniasis due to the presence of cutaneous nodules and cutaneous lesion. Biopsy tissue collections were performed and DNA was extracted. CSB2XF and CSB1XR primers were used to amplify the Leishmania kDNA regions. The Leishmania species were detected by specific 13Z and LIR primers by applying nested PCR assay. Nine dogs were found to be positive for Leishmania major. The examined dogs were negative for other Leishmania spp. The phylogenetic analysis and blast results of kDNA showed that the 9 isolates L. major is closely related (99.9%) to the L. major isolate CMG_irfan5, accession number HQ727556.1 from human, Pakistan. This is the first molecular study on dog leishmaniasis from Saudi Arabia confirmed that dogs have a L. major infection. Further epidemiological and molecular investigations are required to study domestic and wild canine infections with L. major and other Leishmania spp in endemic and nonendemic areas of Saudi Arabia as part of leishmaniasis control.

Abstract
Cardiac resynchronization therapy (CRT) reduces symptoms and improves left ventricular function in patients with heart failure due to left ventricular systolic dysfunction and cardiac dyssynchrony. We analyzed the clinical and echocardiographic outcome of CRT in heart failure patients. Thirty five (35) heart failure patients were included in this prospective observational study, conducted from February 2015 to February 2016 in the Department of cardiology, National Institute of Cardiology & Vascular Disease (NICVD) hospital, Dhaka, Bangladesh. Patients underwent CRT-P (BiV pacemaker) or CRT-D (defibrillator) implantation and were followed up. Clinical, electrocardiographic and echocardiographic study were performed before and 3 months after CRT implantation. After 3 months of BiV pacing, New York Heart Association functional class has improved from 3.3±0.44 to 1.7±0.60; (p<0.001). Left ventricular end diastolic diameter was reduced from 67.9±5.20 to 61.9±5.90mm; (p<0.001) and left ventricular end systolic diameter was reduced from 56.4±6.50 to 50.5±7.20mm; (p<0.001). Ejection fraction was significantly increased from 27.5±4.3% to 38.8±6.7%; (p<0.001). The average grade of mitral regurgitation was decreased from 1.49±0.65 to 0.43±0.61; (p<0.001). The number of hospitalization was also significantly reduced from 2.51±1.44 to 0.11±0.32; (p<0.001). Among the study patients, 71.4% patient was responders, 17.1% super responders and 11.4% non-responders. Although the study was performed on a small number of patients, it can be considered that CRT had favorable hemodynamic and clinical results and reduced the need for hospitalization in our heart failure patients.

Abstract
Pneumonia is the leading cause of morbidity and mortality in children less than 5 years of age in developing countries like Bangladesh. Although WHO guideline classified severe pneumonia by symptoms and signs of the patients, radiological and laboratory investigations were not studied well. There was increasing number of cases of bronchiolitis which meet the criteria of WHO classified severe pneumonia are reported. The objective of the study was to assess the clinical and radiological parameters of severe pneumonia in 2 months to 59 months hospitalized children according to WHO guideline. This cross sectional study was conducted in pediatrics department of Mymensingh Medical College Hospital, Mymensingh, Bangladesh from July, 2015 to December 2015. Total 150 patients were included in this cross sectional study according to their clinical symptoms. Firstly, the chest x-ray was done in all the patients and radiographs were reviewed by an expert radiologist who was blind about the cases. Then the patients were classified as pneumonia and bronchiolitis according to the clinical features and radiology findings. Majority of the patients 83(55.3%) were between 2-6 months of age and mean age was 7.52±8.87. Maximum 105(70%) patients were male and 45(30%) were female. Most of them 70(47%) came from low middle class family. Regarding clinical features, all patients 150 had cough and chest indrawing. Ronchi found in 135(90%) patients, difficult breathing and fast breathing found in 130(87%) patients, crepitation in 122(81%) patients, wheeze in 93(62%) patients, dull on percussion in 36(21%) patients, bronchial breath sound in 25(17%) patients. Regarding radiological features, lobar consolidation was found in 18(12%) patients, patchy opacities in 42(28%) patients, which were radiological findings of pneumonia, while hyperinflation of lung present in 90(60%) patients, increased translucency in 82(54.6%), increased interstitial marking in 88(58.6%) patients, which were radiological findings of bronchiolitis. A total of 60(40%) admitted cases were diagnosed as pneumonia and 90(60%) cases diagnosed as bronchiolitis radiologically, which were predominant in WHO classified severe pneumonia (p<0.05). Wheeze was present in case of hyperinflation of lung in 78(83.8%), increased translucency in 67(72%) and increased interstitial marking in 70(75.2%) patients among radiological bronchiolitis (n=90). From above results we can concluded that Bronchiolitis was predominant among WHO guideline classified severe pneumonia.

Abstract
Complication of perinatal asphyxia is a major cause of neonatal mortality & morbidity in developing countries. This comparative cross sectional study was conducted in Mymensingh Medical College Hospital, Mymensingh, Bangladesh from May 2012 to September 2012 to determine electrolytes & renal function status in perinatal asphyxia & their impact on outcome. Thirty term normal birth weight babies with perinatal asphyxia in neonatal ward were included as a case group and thirty term normal birth weight neonates of same gestational age, without perinatal asphyxia in the department of Gynae & Obs were enrolled as a control group. Necessary information was collected by clinical examination; investigation and close follow up according to predetermined plan. There was no significant different in sex distribution, number of Antenatal care (ANC), number of gravidum of mother and mode of delivery between two groups. Among perinatal Asphyxia group most common risk factor was prolonged labor. Electrolyte abnormalities were documented (16) 53.3% cases. Among 16 electrolyte abnormalities isolated hyponatremia was found in 6(37.5%) cases, hyponatremia with hyperkalaemia 1(6.25%) case, hyponatremia with hypokalaemia in 1(6.25%) case, isolated hypokalaemia in 3(18.75%) cases and isolated hyperkalaemia in 5(31.25%) cases. None case had hypernatremia. On the other hand in control group Hypokalaemia was 3(10%) cases Hyperkalaemia 1(33.33%) case and none had Hyponatraemia. Among total cases 6 (20%) had renal impairment. Serum creatinine level was higher in case group. Twenty percent (20%) case initial value >1.5mg/dl, 20% 1.2-1.5mg/dl and17% had 0.3-0.8mg/dl. On the other hand in control group 83 % had 0.3-0.8 mg/dl & none hade above 1.1 mg/dl. Among case group 8 were died (27%). There was no death in control group. Among 8 neonatal death cases 3(37.5%) had normal electrolytes, isolated hyponatraemia were in 2(25%) cases, hyponatraemia with Hyperkalaemia in 1(6.25%) case and Isolated Hyperkalaemia in 2(25%) cases. Among those death 3(37.5%) had renal impairment. Case fatality was significantly associated with renal failure 50%, isolated Hyponatraemia 33.33%, Isolated hyperkalaemia 40%, Hyperkalaemia with Hyponatremia 100%. Hospital stay was also prolonged among alive case with abnormal electrolytes. So, we can conclude that electrolyte & renal impairments are significantly associated with morbidity & mortality of perinatal Asphyxia.

Abstract
Fulminant hepatic failure is a life-threatening disease. Hepatitis A virus (HAV) can cause fulminant hepatic failure and death in about 0.2% of cases. Extensive destruction of infected hepatocytes by immune-mediated lysis is thought to be the cause. We aimed to evaluate the use of steroid therapy in children with fulminant HAV. This study included 33 children with fulminant HAV in two groups. Steroid group: comprised of 18 children who received prednisolone (1 mg/kg/d) or its equivalent dose of methylprednisolone, and the nonsteroid group: comprised another 15 children who did not receive steroid therapy. Age and sex were matched for both groups (P > .05), and they were comparable regarding baseline clinical and laboratory characteristics. Of the steroid group, 15 patients survived and 3 died, while in the nonsteroid group, 4 patients survived and 11 died (P = .001). Of the living patients, 15 of 19 (78.9%) received steroids while only 3 of 14 (21.4%) of the dead patients received steroids (P = .001). Stepwise regression analysis showed that steroid therapy was the only independent variable associated with recovery (P = .001). Steroid therapy in children with fulminant HAV associated significantly with improved outcome and survival. Future studies on a larger population size are strongly recommended.

Abstract
Serum levels of AFP, hCG and CEA were initially and serially measured in 59 patients with testicular germ cell tumors, and serially in 37 with ovarian and 3 with extragonadal germ cell tumors. Patients with seminoma/dysgerminoma or mature teratoma had normal serum AFP and sporadically slightly elevated hCG. Some patients with embryonal carcinoma, pure or with admixture of seminoma, had serum AFP elevated to maximum 100 U/ml, yet its use for monitoring therapy was limited. Patients with yolk sac tumors had elevated AFP and sometimes CEA levels, those with choriocarcinoma had elevated hCG, and those with compound tumors had one or more of the markers highly elevated. High AFP and/or hCG levels indicated the presence of the relevant tumor cells both in the primary and in residual tumor and/or metastases, also those missed in histological material, and thus were useful in restaging. Unfortunately, their absence in serum did not exclude the presence of marker-negative subpopulations of tumor cells. Changes in marker values paralleled the effects of treatment: the level increasing from any nadir heralded recurrence in patients in remission; elevated or increasing levels during therapy implied resistance to the therapy; decreasing levels indicated regression even though a return to the normal range did not mean eradication of all tumor cells.

Abstract
Multiple pregnancies are a significant risk factor for maternal and perinatal morbidity due to inherent biological risks. The present study was aimed to determine the risk factors and to evaluate the immediate neonatal outcome of multiple pregnancies. This descriptive observational study was conducted in the newly established Special Care Neonatal Unit (SCANU) of Mymensingh Medical College Hospital (MMCH), Bangladesh from January 2015 to March 2015. Total 86 newborns of multiple pregnancies who were admitted during the study period were included in the study. Among them 34 pairs were twin, and 6 sets of triplets were present. Among all infants in the study 79.1% were twin and 20.9% were triplet. According to our observation most of the mother aged between 20-29 years (67.5%) and majorities of them were multi-para (62.5%). Preterm delivery occurred in 70.0% cases. 75% newborns were delivered by caesarian section and remaining by vaginal route. The most common risk factors in present study are use of ovulation induction drugs (52.5%) for sub fertility followed by family history of multiple gestations. In 35.0% cases we did not find any cause. Common morbidities of the infants were preterm low birth weight (95.3%), neonatal jaundice (81.3%), RDS (34.8%), perinatal asphyxia (PNA) (17.4%), neonatal sepsis (25.0%) and congenital anomalies (23.2%). Mortality rate of twin was 30% and for triplets it was 50%. Among total study population mortality rate was 30.2%. Main causes of mortality was preterm low birth weight (76%), RDS (57.6%), septicaemia (26%), PNA (19.0%). Morbidities and mortalities in infants of multiple pregnancies are observed much higher than singleton pregnancy. We hope that in light of our findings regarding risk factors like assisted reproduction and their consequences over mother and newborn, periodic reviews will be done in future to reduce the incidence and the unfavourable outcome of multiple pregnancy.

Abstract
In this study, we investigated the immunomodulatory effects of a supplemented killed influenza virus (V) by Echinacea purpurea (E) and Nigella sativa (N) extracts and effect of changing the route of immunization from intramuscular (IM) to intraperitoneal (IP). At the 2nd-, 3rd- and 4th-week post-IM immunizations (WPIMI), the supplemented V with N (VN) induced the most significant IgM response unlike N alone. At the 2nd WPIMI, V or VN induced the highest significant IgG levels. At the 2nd-week post-IP immunization (WPIPI), E and VN induced the most significant IgG levels. Both at the 3rd and 4th WPIMI or WPIPI, various treatments induced significant increases in IgG. At the 4th WPIMI, E, V, and V with E (VE) induced significant increases in the CD4+ thymocytes while all IP treatments caused significant increase in their counts. V and VN induced the most significant IM induction of CD8+ thymocytes while their best IP stimulation was induced by N, VE, and VN. At the 4th WPIMI, various treatments caused significant increases in the mesenteric lymph node (MLN) CD4+, CD8+ counts. WPIPI with V or VE caused significant increases in both the CD4+- and CD8+ MLN cells, whereas VN significantly induced CD8+ MLN cells only. WPIPI with various treatments caused significant increases in the B-cell counts and the peak was obtained by VN.

Abstract
Low birth weight (LBW) is the most important preventable cause in the neonatal period leading to very high neonatal mortality and morbidity in developing countries like Bangladesh. A cross sectional study was conducted in the neonatology ward, Mymensingh Medical College Hospital, Mymensingh from July 2014 to December 2014 to identify the risk factors and immediate hospital outcome of Very Low Birth Weight (VLBW) Appropriate for Gestational Age (AGA) babies in context of present neonatal hospital care standard. Total 100 preterm very low birth weight babies were enrolled and selected by weight, intra uterine growth chart and new ballad score. There is slight preponderance of male babies (64%) over female babies (36%). The overall survival and mortality rate was 50% and 50% respectively in the present study. Mortality is highest (76.47%) in babies whose gestational age 28 weeks and the mortality rate gradually decrease as gestational age increases. Correlation co-efficient (r) between gestational age and number of died is -0.85. It indicates highly opposite relation between the variables, p value (<0.069) which is strong opposite relation. Mortality is highest (66.66%) in babies whose birth weight below1100gm, in comparison to those whose birth weight above 1100gm and correlation co-efficient (CC) r = -0.433 (p<0.466) which is not significant. That means not only birth weight but also other factors are responsible for mortality of very low birth weight baby. Neonatal mortality bears inverse relationship with birth weight and gestational age. This emphasized the need for large scale study which will provide the guideline for appropriate measures to be taken to combat the situation.

Abstract
The family Molluginaceae (order Caryophyllales) is considered polyphyletic based on the photosynthetic pathway, C4 evolution, and phylogeny of the family. This inference was made based on photosynthetic, anatomical, and molecular datasets. The generic circumscription of this family has greatly been changed owing to the placement of several of its genera into the Caryophyllaceae, Microteaceae, Lophiocarpaceae, and Limeaceae families. However, the generic relationships are largely unknown. By virtue of high substitution rates within the species and the ability to resolve the phylogenetic position of morphologically very closely related species and species complexes, the matK gene has emerged as one of the potential chloroplast DNA molecular markers in plant molecular phylogenetics and DNA barcoding studies. We herein used molecular phylogenetic analyses of matK gene sequences using maximum parsimony and maximum likelihood analyses to infer the generic relationships among currently recognized genera circumscribed under the family Molluginaceae. The resulting phylogenetic tree confirmed the polyphyly of the family Molluginaceae. The genus Hypertelis was found at the base of the Molluginaceae clade. The genus Glinus was close to Glischrothamnus and Mollugo, Suessenguthiella was close to Coelanthum and Pharnaceum, whereas Polpoda grouped with Adenogramma and Psammotropha. The present study constitutes a robust investigation of the molecular phylogenetic relationships among members of the family Molluginaceae. Future study should combine by combined analyses of morphological characters and multiple nuclear and chloroplast DNA sequences with a more comprehensive taxon sampling of the family Molluginaceae.
