Prevalence of Hepatitis B Virus Infection among Children with Liver Disease Admitted In Mymensingh Medical College Hospital

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.

Feasibility of the TARGET-EFT trial in frail and pre-frail cardiovascular inpatients

Funding Acknowledgements

Type of funding sources: None.

Background

Older adults are at risk for hospital-acquired disability and deconditioning, often leading to the "post-hospitalization syndrome" of accelerated functional decline. We hypothesized that this syndrome could be prevented by a pragmatic multi-faceted intervention, and now report the initial experience and feasibility of our ongoing randomized clinical trial.

Methods

Patients admitted to the cardiovascular ward at a single academic center are screened with the Essential Frailty Toolset (EFT). Those ≥65 years with frailty (EFT: 3-5) or pre-frailty (EFT: 1-2) are eligible for the TARGET-EFT trial, in which they are randomly allocated to usual care or intervention. The intervention is targeted such that patients with physical weakness receive supervised exercise sessions (in addition to clinically-indicated physiotherapy), those with cognitive impairment receive stimulation activities, those with iron deficiency anemia receive intravenous iron sucrose, and those with malnutrition-related hypoalbuminemia receive protein supplements. The outcome is a composite score representing mobility, disability, activity, discomfort, and mood (EQ-5D-5L) ascertained by a blinded observer on the day of discharge and at 30 days post-hospitalization.

Results

To date, 77 out of a planned 144 patients have been randomized. The most common reasons for exclusion are age <65 years, expected discharge within <3 days and patient refusal. The median age is 80 years and length of stay is 8 days. In each group, 1 patient withdrew and 1 died. There were no intervention-related adverse events. Of the 39 intervention patients, 36 qualified for exercise and received an average of 6 sessions (46% of sessions were deferred because patients were away for tests, were bedrest post-procedures, or refused), 18 received cognitive stimulation, 15 received intravenous iron sucrose, and 16 received protein supplements.

Conclusion

The TARGET-EFT intervention is feasible and appears safe for frail and pre-frail patients hospitalized with acute cardiovascular disease. Given that nursing staff, physiotherapists, nutritionists and clinicians already address basic cognitive orientation, mobilization and nutritional/iron supplementation needs, it appears that adding targeted interventions for patients’ specific frailty deficits is feasible when shared amongst allied health professionals.

Socio-demographic Profile of COVID-19 Patients and Difficulties Faced by Them while Testing RT-PCR: A Multi-center Cross-sectional Study

This study was aimed to find out the socio-demographic profiles as well as difficulties of Reverse transcription polymerase chain reaction (RT-PCR) testing faced by Coronavirus Disease 2019 (COVID-19) patients. This cross-sectional study was conducted from 10th August to 7th September 2020. Data were collected by telephone interview using a pre-designed questionnaire after taking verbal consent from the participants. Out of 281 COVID-19 patients, 279 were diagnosed by RT-PCR; 10.3% were asymptomatic. Off them 67.6%were males, 24% were hospital staffs. Majority (66.2%) were from the non-city corporation area. History of recent contact with known COVID-19 patients was present in 56.9% cases. Fever (78.3%) and cough (58%) were the most common symptoms. One third of the patients faced difficulty to test RT-PCR for COVID-19. Sixteen percent patients complained of difficulty of getting serial for testing, the maximum waiting time was one week before giving samples. Thirty patients (10.8%) had to wait longer than usual time after reaching the center before giving sample. Hospital staffs were unable to co-operate in 2.5% of the patients while difficulty of managing transport to the hospital for suspected COVID-19 patient was an issue in 2.2% of the patients. Though testing was more difficult in city corporation areas (p=0.028), delay of getting test result was less (p<0.001). Maximum delay of getting test result was 10 days. Finding out the difficulties of COVID-19 testing will help to point out the issues behind these and will help to take necessary steps to tackle this matter. Testing rate can be increased to contain this highly contagious virus in this densely populated country.

Risk Factors of Neonatal Sepsis in Neonatal Intensive Care Unit (NICU) of Mymensingh Medical College Hospital

Neonatal sepsis is associated with increased mortality and morbidity including prolonged hospital stay. Management of such cases is difficult, costly and need expert centers in many cases. Therefore, continued surveillance is mandatory to identify risk factors of neonatal sepsis which help optimizing its management. With the above idea, this cross-sectional descriptive study was conducted at the neonatal intensive care unit (NICU) in the department of Neonatology, Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from July 2017 to December 2017 to observe the effects of maternal and neonatal risk factors in the development of neonatal sepsis and to determine risk factors of neonatal sepsis. Ninety four neonates (0-28 days) who were admitted in NICU with suspected sepsis were included in this study by purposive sampling technique. After admission written informed consent from parents or guardians obtained and histories were obtained including perinatal history and full physical examination of the infants were done and septic screening were sent. All the relevant information was recorded in a pre-designed questionnaire and all data were compiled, tabulated and then analyzed by SPSS version 21.0. Among 94 cases, 72.3% were preterm and 27.6% were term. There was male predominance and male/ female ratio was 1.9:1. Most (76.6%) of the patient admitted within 72 hours of birth. Most (83%) had low birth weight (<2500gm). Most came from rural area 61(64.9%) and also from low income family 59(62.8%). Premature onset of labour 40(42.6%), PROM >18 hours 36(38.3%), vaginal route of delivery 52(55.3%), instrumental resuscitation 15(16%), prelacteal feeding 11(11.7%), bottle feeding 15(16%) were the antenatal, natal and postnatal risk factors in this study. Also the neonatal factors, like prematurity, resuscitation at birth and low APGAR score carried the significant risk of developing sepsis. Poor feeding, lethargy, respiratory distress, jaundice were more common presenting symptoms. Tachycardia, tachypnea, chest indrawing, cyanosis hypothermia, hyperthermia and apnoea were found as more common presenting sign of sepsis in this study. Based on result it is concluded that prolonged rupture of membrane>18 hours, vaginal route of delivery, preterm birth, instrumental resuscitation, prelacteal feeding, bottle feeding were the major perinatal risk factors in this study.

Multiple Optical Features In Binary-Transition-Metal Borate Glasses.. [DOI: 10.21203/rs.3.rs-583999/v1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0]

Glasses doped with transition metal (TM) ions exhibit rich optical transitions spanning the entire ultraviolet, visible, and infrared spectral regimes. Here we utilize the melt-quenching techniques to synthesis binary-TM-doped borate glasses of composition xCuO-(75-x)B2O3-24.7Li2O-0.3Cr2O3, with x = 0, 0.2, 1.0 and 2.0 mol %. We identify several optical transitions from Cr3+, Cr6+, and Cu2+ ions, the latter manifests at longer wavelengths and gains higher intensity with Cu additives. Despite Cr concentration being fixed, the Cr6+ peaks are quenched and Cr3+ signals are barely attenuated. This behavior rules out possible phase separation and suggests non-trivial interplay between the two TM ions and ligand, as supported by probing their oxidation states from electron spin resonance. The crystal field and Racah parameters followed an opposite behavior, while the optical band gap is reduced upon doping. These changes are correlated with structural modifications introduced by Cu additives, where we anticipate homogenous and preferential proximity of Cu-Cr ions within the network.

Green synthesis of silver nanoclusters via Melia azedarach plant and their potential towards catalytic reduction of 4-nitrophenol

Biomolecules present in the plant extracts have potential to reduce metal ions to nanoclusters by a single-step green synthesis approach. In the current study, we have synthesized the silver nanoclusters (AgNCs) from a medicinal plant, Melia azedarach and studied their catalytic activity toward the reduction of 4-nitophenol to 4-aminophenol and organic dyes. Morover, the phytochemical analysis of the plant extract was carried out in order to determine the bioactive compounds present in it. Metallic nature of the synthesized AgNCs was verified by X-ray diffraction study, while their morphology and size of was confirmed by transmission electron microscopy and Zetasizer, respectively. The study revealed that they were 56±2 nm in size and formed clusters. Fourier transformed infrared spectroscopy gives information about the different functional groups present in synthesized these NCs. Furthermore, the important catalytic applications, such as catalytic reduction of 4-nitrophenol in the presence of mild reducing agent NaBH4 and the catalytic degradation of organic dyes was monitored by FTIR. Therefore, these results indicate that the obtained nanomaterials have important applications in industrial areas.                     KEY WORDS: Green synthesis, Silver nanoclusters, Catalytic reduction, Characterization   Bull.

Seed priming with gibberellic acid induces high salinity tolerance in Pisum sativum through antioxidants, secondary metabolites and up-regulation of antiporter genes

Salinity is one of the major abiotic stresses that limit productivity of pulse crops all over the world. Seed priming with phytohormone(s) is one of the most promising, authentic and cost-effective methods to mitigate the deleterious effect of salinity. The study was conducted to investigate potential of seed priming with gibberellic acid (GA3 ) to cope up with the adverse effects of salinity (0, 100, 200 and 300 mm NaCl) in pea (Pisum sativum L.) seedlings. There were different responses to salinity, which induced oxidative stress, higher accumulation of Na+ in shoots and roots and inhibition of photosynthetic traits. However, seed priming with GA3 showed promising effects on physiological traits under salinity stress and alleviated the adverse effects of salinity by inducing the antioxidant system, proline production, total phenol and flavonoid content and regulating ion homeostasis, along with up-regulation of Na+ /H+ antiporters (SOS1 and NHX1). Plants adapt and prevent high salt accumulation by inducing expression of Na+ /H+  antiporter (SOS1 and NHX1) proteins that enhance Na+ sequestration. Thus, seed priming with GA3 is important in alleviation of high salinity stress and can be used as a criterion for developing salt-tolerant cultivars.

Healthy middle-aged Asian and Caucasian populations present with large intra- and inter-individual variations of lower limb torsion

PURPOSE

There is a lack of standardization in the measurement of lower limb torsional alignment. Normal values published in the literature are inconsistent. A 3D-CT-scan-based method was used in a healthy population to define the femoral neck version (FNV) and the tibial torsion (TT) and their relationship with demographic parameters. The study objectives were (1) to define normal values of lower limb torsional alignment, (2) to estimate inter- and intra-individual variations of torsional deformity of healthy individuals' lower limbs. The hypothesis was that FNV and TT values would be influenced by patient characteristics such as gender, age, and ethnicity, and would have low side-to-side asymmetry.

METHODS

Torsional landmarks of the lower limbs from 191 healthy subjects were automatically calculated with a 3D CT-scan-based program. The FNV was defined by the angle between the femoral neck axis and the femoral posterior condylar line. The TT angle was considered between the tibial plateau axis and the axis of the ankle. For the former, two alternatives were considered: the line connecting the more medial and lateral point of the medial and lateral plateau, respectively (method 1; TT1), or the line connecting the two more posterior points of the medial et lateral plateau (method 2; TT2). The ankle axis was defined as the line connecting the medial and lateral malleoli. These reference lines were automatically calculated. Age, gender, ethnic group, and BMI were recorded for every subject. A p value < 0.05 was considered as statistically significant.

RESULTS

Overall, the mean FNV was 15.3 ± 9.5° and the mean TT was 31.6 ± 6.3°. Female hips were more anteverted than male hips. Caucasians had less anteverted hips than Asians, but more externally rotated tibias. Age and BMI were not correlated with any anatomical parameter. A substantial side-to-side asymmetry was found for FNV [absolute difference (AD) = 6.3°; percentage of asymmetry (%As) = 47%], TT1 (AD = 3°; %As = 12%), and TT2 (AD = 4.9°; %As = 9%) (p = 0.008).

CONCLUSION

The findings showed that lower limb torsional parameters were highly variable from patient to patient and from one leg to the other for the same patient. The understanding of normal values concerning femoral version and external tibial torsion in the present healthy population will help surgeons to define pathological values of FNV and TT, as well as corrections to perform in case of torsional deformities.

Endoscopic retrograde cholangiopancreatography for acute gallstone pancreatitis: Implementation of an institution safety protocol during the COVID-19 outbreak in Malaysia

Coronavirus disease 2019 (COVID-19) is a highly contagious, severe acute respiratory syndrome that poses significant health risks to healthcare providers. A delicate balance is needed between timely intervention for ill patients without apparent COVID-19 infection and the safety of healthcare personnel who provide essential treatment in the midst of the pandemic. We report our experience managing a 70-year-old man who presented with acute gallstone pancreatitis at our hospital during the COVID-19 outbreak in Malaysia. We also describe the safety protocol measures that have been implemented in our institution to protect the healthcare personnel from this disease during endoscopic retrograde cholangiopancreatography. This case illustrates the importance of meticulous planning, risk assessment, effective team communication and strict adherence to recommendations when providing treatment during an unprecedented pandemic.

The value of non-invasive computed tomography coronary angiography in imaging patients with coronary artery bypass grafts

INTRODUCTION

Invasive coronary angiography (ICA) is associated with higher complication rates in patients following coronary artery bypass surgery (CABG). CT coronary angiography (CTCA) has emerged as an attractive alternative. We assessed the impact of CTCA on subsequent ICA.

METHODS

We identified 213 CABG patients undergoing CTCA between 2015 and 2018. In 151 the indication was suspected recurrence of angina. We then identified patients undergoing ICA within 1 year of CTCA.

RESULTS

CTCA obviated the need for ICA in 115 cases (76%). CTCA was better at identifying targets for percutaneous coronary intervention (PCI) to saphenous vein grafts (SVG's) than to native vessels (89% vs 47%). 7 out of 10 lesions of "probable" significance by CTCA proved flow-limiting, and 4 out of 13 "indeterminate" lesions. CTCA concordance was 97% for left internal mammary (LIMA) grafts.

CONCLUSION

CTCA directed management in a majority of patients without ICA. It identified a cohort of patients likely to be candidates for SVG PCI, but was less effective in identifying PCI targets in the native vessels. CTCA renders invasive LIMA cannulation redundant unless a target lesion is suspected.

Extraction and optimization of chitosan from razor clam (Ensis arcuatus) shells by using response surface methodology (RSM)

Chitin can be found in animal source especially arthropods such as crustacean, mollusk and insect, as well as in plant source such as fungi. Chitosan is obtained from chitin after the acetyl group is removed from chitin structure through deacetylation step and has wide application in various fields (food, cosmetics and pharmaceutical). In this study, chitosan was extracted from razor clam shells, where the extraction conditions were optimized. Two- factors of randomized D-optimal design was used to determine the optimum condition for the extraction of chitosan from razor clam (Ensis arcuatus) by using response surface methodology (RSM). The chemical extraction was optimized using five levels with two factors which were the deacetylation time (2,4,6,8,10 hrs) and deacetylation temperature (50, 60, 70, 80 and 90ºC). A randomized design suggested by Design Expert software was implemented with four responses evaluated: yield (%); degree of deacetylation (%); molecular weight (kDA); and ash content (%). Time (h) and temperature (ºC) of the deacetylation significantly (p<0.05) affected the yield (%), degree of deacetylation (DDA) (%), molecular weight (Mw) (kDA) and ash content (%) of the chitosan extracted. The optimum conditions for the chitosan extraction were at the respective deacetylation time and temperature of 6h and 70ºC with actual values of yield (%), degree of deacetylation (%), molecular weight (kDA) and ash content (%) of 19.903±2.367, 50.113±0.902, 476.727±13.603, 8.517±2.094, respectively. The optimum condition for the chitosan extraction was experimentally verified and valid for further analysis.

Long-term safety and efficacy of trifarotene 50 μg/g cream, a first-in-class RAR-γ selective topical retinoid, in patients with moderate facial and truncal acne

BACKGROUND

Treatment for both facial and truncal acne has not sufficiently been studied.

OBJECTIVES

To evaluate the long-term safety and efficacy of trifarotene in both facial and truncal acne.

METHODS

In a multicentre, open-label, 52-week study, patients with moderate facial and truncal acne received trifarotene 50 μg/g cream (trifarotene). Assessments included local tolerability, safety, investigator and physician's global assessments (IGA, PGA) and quality of life (QOL). A validated QOL questionnaire was completed by the patient at Baseline, Week 12, 26 and 52/ET.

RESULTS

Of 453 patients enrolled, 342 (75.5%) completed the study. Trifarotene-related treatment-emergent adverse events (TEAEs) were reported in 12.6% of patients, and none was serious. Most related TEAEs were cutaneous and occurred during the first 3 months. Signs and symptoms of local tolerability were mostly mild or moderate and severe signs, and symptoms were reported for 2.2% to 7.1% of patients for the face and 2.5% to 5.4% for the trunk. Local irritation increased during the first week of treatment on the face and up to Weeks 2 to 4 on the trunk with both decreasing thereafter. At Week 12, IGA and PGA success rates were 26.6% and 38.6%, respectively. Success rates increased to 65.1% and 66.9%, respectively at Week 52. Overall success (both IGA and PGA success in the same patient) was 57.9% at Week 52. At Week 52 visit, 92/171 (53.8%) patients who had completed their assessments had scores from 0 to 1 (i.e. no effect of acne on their QOL) vs. 47/208 (22.6%) patients at Baseline visit.

CONCLUSION

In this 52-week study, trifarotene was safe, well tolerated and effective in moderate facial and truncal acne.
