RESUMEN

Evaluation of the in vitro antibacterial activity of Chloroform extracts isolated from Henna (Lawsonia inermis) leaf against two nosocomial infection causing pathogens, gram-positive Staphylococcus aureus and gram-negative Klebsiella pneumoniae. This interventional study was carried out for the period of January 2021 to December 2021 in the Department of Pharmacology and Therapeutics in collaboration with the Department of Microbiology, Mymensingh Medical College, Bangladesh. The antibacterial activity was tested at different concentrations of Chloroform Henna leaf extracts by using disc diffusion and broth dilution method. The extract was prepared by using solvents chloroform and 0.1% Dimethyl sulfoxide (DMSO). The test microorganisms were also tested for their activity against a standard antibiotic Ciprofloxacin by broth dilution method and the result was compared with that of Chloroform extracts. Chloroform Henna Extracts (CHE) were used initially in nine different concentrations (2.5, 5, 10, 20, 50, 100, 200, 500 and 1000 mg/ml). Among different concentrations of the CHE, 100mg/ml and above concentrations showed inhibitory effect against Staphylococcus aureus and Klebsiella pneumoniae. The MIC for Staphylococcus aureus and Klebsiella pneumoniae were 100 and 200mg/ml in CHE respectively. The MIC of Ciprofloxacin was 1µg/ml against Staphylococcus aureus and 1.5µg/ml against Klebsiella pneumoniae. The MIC of Ciprofloxacin was the lowest in comparison to MICs of CHE for the test organisms. This study showed that Chloroform Henna extracts demonstrated antibacterial effects against food borne pathogens. It is clearly observed that there is definite antibacterial effect of the Chloroform extract of Henna leaves (Lawsonia inermis) against Staphylococcus aureus and Klebsiella pneumoniae.

RESUMEN

OBJECTIVE: To examine prevalence of novel newborn types among 541 285 live births in 23 countries from 2000 to 2021. DESIGN: Descriptive multi-country secondary data analysis. SETTING: Subnational, population-based birth cohort studies (n = 45) in 23 low- and middle-income countries (LMICs) spanning 2000-2021. POPULATION: Liveborn infants. METHODS: Subnational, population-based studies with high-quality birth outcome data from LMICs were invited to join the Vulnerable Newborn Measurement Collaboration. We defined distinct newborn types using gestational age (preterm [PT], term [T]), birthweight for gestational age using INTERGROWTH-21st standards (small for gestational age [SGA], appropriate for gestational age [AGA] or large for gestational age [LGA]), and birthweight (low birthweight, LBW [<2500 g], nonLBW) as ten types (using all three outcomes), six types (by excluding the birthweight categorisation), and four types (by collapsing the AGA and LGA categories). We defined small types as those with at least one classification of LBW, PT or SGA. We presented study characteristics, participant characteristics, data missingness, and prevalence of newborn types by region and study. RESULTS: Among 541 285 live births, 476 939 (88.1%) had non-missing and plausible values for gestational age, birthweight and sex required to construct the newborn types. The median prevalences of ten types across studies were T+AGA+nonLBW (58.0%), T+LGA+nonLBW (3.3%), T+AGA+LBW (0.5%), T+SGA+nonLBW (14.2%), T+SGA+LBW (7.1%), PT+LGA+nonLBW (1.6%), PT+LGA+LBW (0.2%), PT+AGA+nonLBW (3.7%), PT+AGA+LBW (3.6%) and PT+SGA+LBW (1.0%). The median prevalence of small types (six types, 37.6%) varied across studies and within regions and was higher in Southern Asia (52.4%) than in Sub-Saharan Africa (34.9%). CONCLUSIONS: Further investigation is needed to describe the mortality risks associated with newborn types and understand the implications of this framework for local targeting of interventions to prevent adverse pregnancy outcomes in LMICs.

RESUMEN

Electrocyclic reactions are characterized by the concerted formation and cleavage of both σ and π bonds through a cyclic structure. This structure is known as a pericyclic transition state for thermal reactions and a pericyclic minimum in the excited state for photochemical reactions. However, the structure of the pericyclic geometry has yet to be observed experimentally. We use a combination of ultrafast electron diffraction and excited state wavepacket simulations to image structural dynamics through the pericyclic minimum of a photochemical electrocyclic ring-opening reaction in the molecule α-terpinene. The structural motion into the pericyclic minimum is dominated by rehybridization of two carbon atoms, which is required for the transformation from two to three conjugated π bonds. The σ bond dissociation largely happens after internal conversion from the pericyclic minimum to the electronic ground state. These findings may be transferrable to electrocyclic reactions in general.

RESUMEN

To assess the role of the Glasgow Comma Score (GCS) for predicting the outcome of the patient with fever and altered sensorium was the objective of the study. This prospective observational study was conducted for six months following ethical approval. Informed consent was obtained prior enrollment. A total of 50 patients with complaints of fever for <2 weeks duration with altered sensorium with or without seizure were included in the study. GCS was calculated for all patients just after admission and before starting interventions. All patients were investigated and managed according to the hospital protocol. The outcome of the patients (living or dead within the hospital) was evaluated against the admission GCS score. The study was performed in accordance with the current Declaration of Helsinki. Of all, 42.0% (n=21) of the patients had bacterial meningitis, followed by viral encephalitis, cerebral malaria and coma vigil. Complete recovery occurred in 60.0% of cases, while recovery with disability occurred in 28.0% of cases. Death occurred in 12.0% of cases (n=6) due to cerebral malaria, viral encephalitis and bacterial meningitis (n=2 each cause). A higher number of deaths occurred in the lower GCS group (n=5 in GCS group 3-5) and this difference was statistically significant (p<0.05). Moreover, considering death as an outcome, multivariate logistic regression showed that GCS (OR 70.598, 95% CI-1.243-4009.41; p=0.039) was an independent predictor of the outcome. GCS seemed to be a predictor of the short-term outcome of the patient presenting with fever and altered sensorium in our setting. However, further exploration in larger setting with appropriate study design is recommended.

RESUMEN

The main objective of this paper is to improve the identification efficiency of non-linear systems using the Kalman filter (KF), which is optimised with the Artificial Electric Field (AEF) algorithm. The conventional KF suffers from the proper tuning of its parameters, which leads to a divergence problem. This issue has been solved to a great extent by the meta-heuristic AEF algorithm assisted Kalman filter (AEF-KF). This paper proposes three steps for the identification of the systems while solving the problem as mentioned above. Firstly, it converts the identification model to a measurement problem. Next, the AEF algorithm optimises the KF parameters by considering the fitness function with the KF equations. The third step is to identify the model using conventional KF algorithm with the optimised KF parameters. To evaluate the performance of the proposed method, parameter estimation error, mean squared error (MSE), fitness (FIT) percentage, statistical information and percentage improvement are considered as the performance metrics. To validate the performance of the proposed method, five distinct non-linear models are identified with the Volterra model using KF and the AEF-KF techniques under various noisy input conditions. Besides, the practical applicability of the proposed approach is also tested on two non-linear benchmark systems using experimental data sets. The obtained simulation results confirm the efficacy and robustness of the proposed identification method in terms of the convergence speed, computational time and various performance metrics as compared to KF, Kalman smoother (KS) which is optimised using different state-of-the-art evolutionary algorithms and also other existing recently reported similar types of stochastic algorithms based approaches.

RESUMEN

Conformational isomers (conformers) of molecules play a decisive role in biology and organic chemistry. However, experimental methods for investigating chemical reaction dynamics are typically not conformer-sensitive. We report on a gas-phase megaelectronvolt ultrafast electron diffraction investigation of α-phellandrene undergoing an electrocyclic ring-opening reaction. We directly imaged the evolution of a specific set of α-phellandrene conformers into the product isomer predicted by the Woodward-Hoffmann rules in real space and time. Our experimental results are in quantitative agreement with nonadiabatic quantum molecular dynamics simulations, which provide considerable detail of how conformation influences the time scale and quantum efficiency of photoinduced ring-opening reactions.

RESUMEN

Healthcare professionals are the crucial and influencing source of information for vaccines and their communication among patients and communities that can accelerate successful vaccination in a country. This cross-sectional study was one of the first and foremost ones in Bangladesh to observe the basic perception and attitudes towards vaccination against COVID-19 among the healthcare workers (HCWs) - doctors, interns, nurses, ward boys, cleaners, and medical technologists of major COVID-dedicated hospitals. The cross-sectional questionnaire-based study was conducted in February 2021 among 550 HCWs to assess the perception and attitude towards vaccination against COVID-19. The study participants were targeted as the priority group for COVID-19 vaccination, working in two major COVID-dedicated hospitals, Holy Family Red Crescent Medical College Hospital (HF-center), and Sheikh Russel National Gastro-liver Institute and Hospital (SR-center) in Dhaka, Bangladesh during the pandemic. The questionnaire was structured with a three-point scale of responses from 'true', 'false', and 'do not know'. The responses were calculated on point-score as +1 for the correct response, -1 for the wrong response, and 0 for 'do not know' with an overall highest and the lowest possible score of +5 to -5. Absolute (n) and relative frequencies (%) were presented for qualitative variables, while quantitative variables were presented as mean (± standard deviation). Chi-square test was done for univariate analysis of qualitative variables and Student's t-test for quantitative variables. With the 95.27% response rate, including 204 males and 320 were female and the male: female ratio was 1: 1.56. The majority of the participants were doctors (45.8%) followed by nurses (27.9%), and MLSS (26.3%) respectively. The respondents were between 18 to 64 years of age with a mean of 36.17±10.94 years. Most of the respondents (95.99%) responded correctly about the cost-free availability of a vaccine against COVID-19 in the country, 87.40% preferred vaccination as safe and effective. Again 29.77% HCWs think the vaccine might not be safe or effective due to emergency authorization. Only 38.93% of respondents could respond correctly about the necessity of vaccines for children, 31.10% think the vaccination was not required instead of natural immunity. The positive perception and attitude of the frontline HCWs in COVID-dedicated hospitals in Bangladesh are crucial which will positively influence motivation and wide acceptance among the general population for the attainment of the nationwide vaccination program, and adopt effective strategic modification to minimize the gaps for a low-middle income country like Bangladesh with its resource constrain.

RESUMEN

Pancreaticobiliary diseases are the important causes of morbidity and mortality worldwide. Among the imaging modalities, Transabdominal ultrasound (TUS) is cheap, available, and noninvasive but it has some limitations. Endoscopic ultrasound (EUS) is invasive but it has some diagnostic and therapeutic advantages over TUS. This study was aimed to see the diagnostic yields of EUS and TUS in the pancreatobiliary diseases. This cross sectional study was conducted in Sir Salimullah Medical College Mitford Hospital (SSMC&MH), Dhaka, Bangladesh from March 2017 to February 2019. All (n=222) patients were evaluated clinically and with relevant investigations. TUS and EUS were done in all patients. Endoscopic retrograde cholangiopancreatography (ERCP) was done in 60 patients. Among 222 patients 56.8% were males; mean age was 46±16 years; the main presenting symptoms were abdominal pain and jaundice. In diseases of biliary tree, EUS showed dilated CBD alone or in combination with stone in 50 and 67 cases and TUS showed 37, 63 patients respectively. The difference between the findings of EUS and TUS was statistically significant (p=0.00). In gall bladder, EUS found microlithiasis in 6(2.6%) and sludges in 24(10.8%) cases whereas TUS found microlithiasis in 1(0.5%) and sludges in 17(7.7%) cases respectively (p=0.00). Both EUS and TUS detected cholelithiasis in equal number of patients 46(20.3%). On pancreatic evaluation, EUS and TUS detected pancreatic parenchymal abnormalities in 24(10.8%) and 12(5.5%) patients respectively with significant p value (0.00). In cases of pancreatic and cholangiocarcinoma the difference between the findings of EUS and TUS were statistically significant (p<0.05). EUS detected 7 cases of ampullary/peri-ampullary neoplasms whereas TUS detected only 2 cases. The sensitivity of EUS for detecting CBD dilatation, CBD stones, CBD SOL and pancreatic SOL was 85%, 91%, 93%, and 92% respectively. The sensitivity of TUS for detecting CBD dilatation, CBD stones, CBD SOL and pancreatic SOL was 42%, 52%, 40%, and 37% respectively. EUS is more sensitive than TUS in diagnosing pancreaticobiliary disorders. It is of paramount importance in patients in diagnosing CBD dilatation, choledocholithiasis, biliary microlithiasis and pancreaticobiliary neoplasm. EUS has important role before proceeding to further management by more invasive techniques like ERCP or surgery.

RESUMEN

The sudden outbreak of a novel coronavirus in 2019 in Wuhan, China, that rapidly provoked a global concern, marked as the third attack of corona virus in the human society that affected the global healthcare system as well as the global economy. Until and unless an effective vaccine is discovered against the virus, the pharmacological intervention by different antivirals is in the run for remedy. The aim of this systematic review was to evaluate the role of favipiravir along with its safety and efficacy for the patients who are suffering from severe acute respiratory distress syndrome due to CoronaVirus-2 (SARS-CoV-2) as re-purposeful use. We searched PubMed, EMBASE for randomized controlled trials (RCTs), cilicaltrial.com for registered on going trails to evaluate the pros and cons of using favipiravir in COVID-19. After vigorous searching, screening and sorting of 314 articles for completed and published scientific evidences in electronic database, there were only 2 completed and published randomized control trials (RCT) and 17 ongoing or unpublished trials found until June 2020. The main outcome measures were viral clearance, clinical improvement and adverse events reported and published on 147 patients infected with SARS-CoV2. The 2 completed RCTs showed significantly better treatment effects on disease progression, viral clearance, improved the latency to relief for pyrexia and cough on favipiravir treated patients. Adverse effects caused Favipiravir are mild and manageable. Although 9 more RCTs and cohort studies are supposed to be completed by this time that may unveil some evidence for use of anti-RNA-viral drug favipiravir against influenza or Ebola to re-purposing against COVID-19 as adopted in different treatment guidelines.

RESUMEN

Cinnamomum zeylanicum as medicinal plants are measured as new resources for preparing elements in the treatment of antibiotic-resistant microbes as alternatives to antibiotics. This study was aimed to evaluate the antibacterial activity of ethanol extracts of Cinnamomum zeylanicum against a Gram-negative bacteria Pseudomonas aeruginosa. This experimental study was carried out in the department of Pharmacology & Therapeutics and department of Microbiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2017 to July 2018. Evaluation of the in vitro antibacterial activity of ethanol extracts of Cinnamomum zeylanicum against Pseudomonas aeruginosa was performed by disc diffusion method. And also in this study we used broth dilution method to determine the minimum inhibitory concentration (MIC). Ethanol cinnamon extract (ECE) was found active against P. aeruginosa. Zone of inhibition (ZOI) ranged between 6-25mm at different concentration of extracts. The MIC was 0.3g/ml. Cinnamomum zeylanicum showed strong antibacterial activity against a Gram-negative bacteria Pseudomonas aeruginosa. The results may contribute to the development of potential antimicrobial agents for inclusion in antipseudomonal regimens.

RESUMEN

The rapid progression of corona virus disease in 2019 (COVID-19) pandemic has become an unprecedented global concern. This systemic review aimed at evaluating the available evidence on efficacy, safety to identify any promising role for compassionate use of remdesivir in patient suffered for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) as re-purposeful use. We searched PubMed, EMBASE, Cochrane Library for randomized controlled trials (RCTs), prospective case series studies and case reports that evaluated use of remdesivir in COVID-19. The outcomes were mortality, recovery rate, length of hospital stay and clinical outcome. Though the drug remdesivir (RDV) is not approved by the FDA, still the "Emergency Use Authorization" (EUA) for compassionate use in severe cases is endorsed. After vigorous searching, screening and sorting of completed and published scientific evidences in electronic database, there were only 2 randomized control trial (RCT), 2 uncontrolled trials found until April 2020. We also included 3 published case reports to analyze the validity use of RDV because of the scarcity of evidence based reports. Remdesivir was thought to be one of the promising options for treating the patients of COVID-19 based on few laboratory experiments and reports from some compassionate use and case reports. The safety and efficacy of this drug in COVID-19 cases require high-quality evidence from well-designed and adequately-powered clinical trials with proper sample size for precise decision.

RESUMEN

This study was aimed to compare the long-term outcomes and survival rate among mitral valve replacement using thoracotomy and standard median sternotomy in a single surgeon's practice. Total 250 patients were evaluated; Group I (n=65) patients had anterolateral thoracotomy and Group II (n=185) had standard median sternotomy for valve replacement. Mean age was 25.1±5 years in Group I and 41.8±10.5 years in Group II. Female was predominant in Group I. Total operative time and bypass time was statistically significant in Group I (235.5±25.8 minutes; 84.2±12.75 minutes) in contrast to Group II (203.8±15.5 minutes; 71.5±10.5 minutes). Incision scar was not visible in females in Group I but full incision scar was visible in Group II. Post-operative ICU stay duration was significant high in Group II. Though, wound infection incidence was 0% in Group I; however, 9.73% patient had wound infection in Group II. Only 1.62% patient developed unstable sternum in Group II. Most of the patients from both study group were in regular follow up and 1-year mortality rate was 4.62% and 5.94% in Group I and Group II respectively. Mitral valve replacement through a right anterolateral thoracotomy is easy and safe to perform; while getting maximum benefits for the patients. Besides satisfactory cosmetic outcome especially in female, this approach provides better exposure to mitral apparatus even in patients with small left atrium, cost effectiveness, less duration of hospital stays and absence of the risk for unstable sternum.

RESUMEN

Evaluation of the in vitro antibacterial activity of the ethanolic extract isolated from Cinnamomum zeylanicum bark against two food borne pathogens, Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli. This experimental study was carried out in the department of Pharmacology & Therapeutics in collaboration with the department of Microbiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2017 to July 2018. The antibacterial activity was tested at different concentrations of extracts of spice by using disc diffusion method. The extracts were prepared by using a solvent ethanol. The test microorganisms were also tested for their activity against a standard antibiotic Amikacin (500mg) by disc diffusion method and the result was compared with that of ethanolic extracts. Cinnamon had inhibitory activity against both Staphylococcus aureus and Escherichia coli. The ethanolic extracts were more effective against Staphylococcus aureus than E. coli. Staphylococcus aureus showed activity from 60% conc. (zone of inhibition 17mm) where E. coli from 80% conc. (ZOI 18mm). Maximum zone of inhibition was 26mm for both the test organisms. This result was also compared to those obtained against a standard antibiotic Amikacin where extract produced wider zone of inhibition of 26mm as compared to Amikacin for both test organisms. The present study showed that ethanolic extract of cinnamon demonstrated stronger antimicrobial effect against food borne pathogens.

RESUMEN

Evaluation of the in vitro antibacterial activity of aqueous and ethanolic extracts isolated from Clove (Syzygium aromaticum) buds against three food borne pathogens, gram-positive Staphylococcus aureus and gram-negative Escherichia coli & Pseudomonas aeruginosa. This interventional study was carried out during the period of July 2018 to June 2019 in the Department of Pharmacology and Therapeutics with the collaboration of Department of Microbiology, Mymensingh Medical College, Mymensingh, Bangladesh. The antibacterial activity was tested at different concentrations of both extracts of spice by using disc diffusion & broth dilution method. The extracts were prepared by using solvents aqueous & ethanol. The test microorganisms were also tested for their activity against a standard antibiotic Gentamicin (80mg) by broth dilution method and the result was compared with that of Aqueous and Ethanolic extracts. Aqueous and ethanolic extracts of clove had inhibitory activity against the test bacteria. Among different concentrations of the ACE, 500µg/ml & above concentration showed inhibitory effect against Staphylococcus aureus & Escherichia coli and 700µg/ml & above concentration showed inhibitory effect against Pseudomonas aeruginosa. In case of ECE, 500µg/ml & above concentration showed inhibitory effect against aforesaid bacteria. In disc diffusion method, S. aureus was found to be most susceptible to ACE (30.5mm) & Pseudomonas aeruginosa was found to be most susceptible to ECE (38mm). Minimum inhibitory concentrations (MIC) of ECE were lower than ACE for the test bacteria except Staphylococcus aureus where MICs of ACE & ECE were the same. This result was also compared against a standard antibiotic Gentamicin where the MICs of Gentamicin were lower in comparison to MICs of ACE & ECE. The present study showed that aqueous and ethanolic extracts of Clove demonstrated antibacterial effects against food borne pathogens.

RESUMEN

This study aimed to evaluate myocardial protective effect of isoflurane and propofol as a fast tract anesthesia in off pump coronary artery bypass graft surgery by measuring postoperative cardiac enzyme Troponin-I, and liver enzyme. The study was conducted on 260 patients scheduled to undergo elective off pump coronary artery bypass graft surgery. Patients were randomly allocated to receive either isoflurane or propofol anesthesia and was aimed to extubated within 6 hours. Troponin-I levels were measured preoperatively, at arrival in postoperative intensive care unit, at 12, 24, 48, 72 hours and 4 weeks following surgery. Liver function was also assessed and compared between preoperative and postoperative values. There is no difference in Troponin-I levels between the two studies groups at observed pre and post-operative time intervals. Fast tract anesthesia using isoflurane and propofol provides same myocardial protection during and after OPCABG and overall outcome was excellent.

RESUMEN

Neonatal sepsis is one of the most common reasons for admission to neonatal units in developing countries. It is also a major cause of mortality in both developed and developing countries. The type and pattern of organisms that cause neonatal sepsis changes over time and vary from one hospital to another hospital, even in the same country. In addition the causative organisms have developed increased drug resistance for the last two decades. Maternal, neonatal and environmental risk factors have contributed for the development of sepsis. To study the risk factors, causative organism and bacterial sensitivity pattern in cases of neonatal sepsis. This cross-sectional study was conducted over a period of six months. The study included 100 patients admitted at the neonatal ward of Department of Pediatrics, Community Based Medical College Bangladesh, Mymensingh, Bangladesh. Blood samples for culture were taken aseptically before starting antibiotic therapy. Microorganisms were isolated and identified by standard microbiological processes and antimicrobial sensitivity patterns were performed against amikacin, gentamicin, ceftriaxone, ciprofloxacin and ceftazidime. The factors which carried a significant risk for development of neonatal sepsis were low birth weight, preterm neonates, meconium stained liquor and prolonged rupture of membrane (>18 hours). Gram negative organisms predominated (68.8%) with Escherichia coli (33.3%) being the commonest. The gram negative bacteria which were isolated sensitive to amikacin, gentamicin and ceftriaxone. The organisms also relatively more sensitive to ciprofloxacin and highly sensitive to ceftazidime. The Gram positive bacteria showed sensitivity against only the antibiotic Ceftriaxone and Ciprofloxacin. The overall mortality was 9%. The outcome of the study will contribute to preventing and treating neonatal sepsis in the hospital.

RESUMEN

Hepatocellular carcinoma (HCC) is an important reason of liver-related death globally. HCC is the fifth most common cancer, the third most common cause for cancer related death in the world and responsible for approximately one million deaths each year. The incidence of HCC is expected to increase in the next two decades, largely due to hepatitis C infection and secondary cirrhosis. We have reported a case of hepatocellular carcinoma in a 56-year-old man with peritoneal metastasis. Diagnostic imaging (Ultra sonogram & CT-Scan) shown: a large hypo density, irregular outline lesion noted in right lower liver, post contrast image shown patchy enhancement of the lesion. His serum Alpha-Feto Protein (AFP) level was very high with elevated serum alanine amino transaminase (ALT) enzyme and prothrombin time. Histopathological (microscopic) features are compatible with Hepatocellular carcinoma. His Hepatitis C viral DNA load e.g., core protein variants and genotype 1, have been reported. The patient was treated by surgical resection followed by conservative treatment includes sorafenib & interferon alpha. This case report aims to outlines the epidemiology of HCC in chronic HCV, risk factors and pathophysiology that contribute to this disease process, related pathophysiology of patient's clinical features, screening recommendations, and the available statistics on the impact of new direct-acting antiviral treatment on the development on HCC.

RESUMEN

This experimental study was carried out to determine the antibacterial effect of Ethanolic extract of Aloe vera leaf gel (EAE) against standard strains of Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Klebsiella pneumoniae in the Department of Pharmacology & Therapeutics in collaboration with the Department of Microbiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2017 to June 2018. Ethanol extract was used in five different concentrations (100, 200, 300, 400 and 500µg/ml). Dose dependent inhibitory effect was seen against the test organisms using disc diffusion method. For S. aureus, Zones of inhibition (ZOI) were 7, 12, 13, 16 and 20 mm at 100, 200, 300, 400 and 500 µg/ml respectively; for P. aeruginosa, ZOI were 0, 7, 12, 14 and 17 mm at 100, 200, 300, 400 and 500 µg/ml respectively; for E. coli, ZOI were 0, 8, 12, 15 and 18 mm at 100, 200, 300, 400 and 500 µg/ml respectively; for K. pneumoniae, ZOI were 7, 10, 11, 13 and 17 mm at 100, 200, 300, 400 and 500 µg/ml respectively. The minimum inhibitory concentration (MIC) was assessed by broth dilution technique. The MICs of EAE for S. aureus, P. aeruginosa, E. coli and K. pneumoniae were 500, 650, 650 and 600 µg/ml respectively. From the study it is clearly observed that ethanolic extract of Aloe vera leaf gel possesses antibacterial effect against the test pathogens. Further studies are required to detect and isolate the biologically active ingredients present in the Aloe vera leaves which are responsible for this antibacterial effect. Hopefully, that would lead to the discovery of new and more potent antimicrobial agents originated from Aloe vera.

RESUMEN

Disease of the spinal cord is called myelopathy which are frequently devastating. They produce motor weakness in the form of quadriplegia or paraplegia, sensory impairment, with a definite anatomical level, and loss of sphincteric function far beyond the site of damage. Many spinal cord diseases are reversible if known and treated at an early stage. Purpose of this study is to evaluate clinical presentation and aetiology of myelopathic patients on the basis of history, clinical examination and investigations. Patients getting admission in indoor of Medicine, Neuromedicine and Neurosurgery units of Rajshahi Medical College Hospital, Rajshahi, Bangladesh from March 2013 to August 2013, having complains of spastic paraplegia and quadriplegia or flaccid type of paralysis with sensory level or bowel bladder disturbance. This cross-sectional descriptive study was done with total 44 myelopathic patients were evaluated. Out of 44 patients, 75% were male and 25% were female (ratio 3:1), mean age 35±13.9 years (range 13-65 years). Among them 54.5% patients had paraparesis and 45.5% patients had quadriparesis. Sensory disturbance had 70.45%, 68.18% had urinary sphincter disturbance and 22.72% had bladder sphincter disturbance. Among the aetiology of myelopathy the commonest cause was cervical spondylotic myelopathy 31.8%, second cause was acute transverse myelitis 20.5% and third cause was Pott's disease 18.2%. It was observed that majority (75%) of them had compressive type and 25% patients had non-compressive type of involvement. Myelopathy was three times more common in male than female. Cervical spondylotic myelopathy & transverse myelopathy was the main aetiology of compressive and non compressive myelopathy respectively.

RESUMEN

The aim of the present study was to assess the patient characteristics associated with medication adherence to anti-diabetic drugs. This observational, cross sectional study was conducted from January 2016 to June 2016 among patients attending at endocrine outpatient department of the Mymensingh Medical College Hospital and Medicine outpatient department of the Community Based Medical College Hospital, after obtaining requisite consent from the patients. Once the consultation by the physician was over, the patients were interviewed. Medication adherence was assessed through the specific four questions patient questionnaire, the modified morisky medication adherence scale that has high reliability and validity and the patient was considered to be highly adherent if he or she answered in the negative to all four questions (score-0). All filled questionnaires on the pattern of medication adherence to anti-diabetic drugs were entered into the computer for subsequent analysis using SPSS method version 20.1. Male patients had shown high rate of adherence than female. Elderly patients were more adherent. Urban patients had shown higher rate of adherence compared to rural. Patients with higher secondary education and businessman had higher compliance. Improved medication adherence was seen in patients with diabetes mellitus for long duration (>10 years). Our results had shown that therapeutic adherence was significantly affected by different patient - centered factors like age, educational status, employment status, and place of residence.
