Association of CSF Total Protein with Clinical Heterogeneity, Disease Severity and Electrophysiological Pattern in GBS Patients.

Guillain-Barre Syndrome (GBS) is considered as an immune mediated inflammatory disease of peripheral nerves and nerve roots. The significance of CSF total protein (CSF-TP) in subtypes of Guillain-Barre syndrome has not been well established. This observational, cross sectional study's aim was to identify association of CSF total protein with clinical heterogeneity, disease severity and electrophysiological subtypes in GBS patients. This study was carried out in the Department of Neurology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh from September 2017 to February 2019 on 50 (fifty) admitted GBS patients as per inclusion and exclusion criteria. About 3-5 ml of CSF was taken around 10±2 days from disease onset for detection CSF cell count and protein. Pattern of clinical presentation, disability status by Hughes scale and NCS findings of these patients was documented. Mean CSF-TP were substantially higher for Sensori-motor GBS (195.42 mg/dl) and GBS with cranial involvement (226.12 mg/dl) than that of GBS with motor (134.00 mg/dl) and autonomic involvement (155.21 mg/dl). Mean CSF total protein (CSF-MTP) in severely ill GBS patients (Grade-IV) was 217.04 mg/dl and very severely ill GBS patients (Grade-V) was 138.00mg/dl which was significantly higher than mean CSF total protein in mild GBS patients (CSF-MTP: 99.86mg/dl) and moderately ill GBS patients (CSF-MTP: 172.00 mg/dl). Mean CSF total protein is 245.00mg/dl in AIDP which is also higher than mean CSF total protein of AMAN (153.36 mg/dl) and AMSAN (165.17mg/dl). CSF-TP is thought to be a sensitive test for GBS in the second week after onset, but it may be a reliable predictor of clinical severity. There is a significant association of CSF-TP elevation with demyelinating electrophysiologic pattern.

Effect of the Dynamic Orthotic Garment on Postural Control, and Endurance in Children with Spastic Diplegic Cerebral Palsy: A Randomized Controlled Trial.

Purpose: To investigate the effect of dynamic orthotic garments (Thera togs) on foot pressure distribution, postural control, and endurance in children with spastic diplegic CP. Patients and Methods: This is a single-blind randomized controlled clinical trial involving 34 (8-10 years) with spastic diplegic CP. The control group received conventional physical therapy (CPT), whereas the study group received CPT in addition to wearing TheraTogs. We recorded foot pressure distribution, trunk control measurement scale, trunk position sense, Pediatric Berg Balance Scale (PBS), and six-minute walking distance (6MWD). Results: Both groups showed improvement. The study group had significant improvement in foot pressure distribution (p-value 0.003, 0.001, <0.001 for forefoot, midfoot, and rearfoot mean pressures respectively, and 0.005, <0.001, and 0.005 for forefoot, midfoot, and rearfoot peak pressures respectively), Pediatric balance scale, The trunk control measurement scale, and Trunk position sense (p-value < 0.001) and six-minute walking distance (p-value 0.029). Our data suggest that adding TheraTogs to conventional physiotherapy improves foot pressure, postural control, and endurance in children with spastic diplegic cerebral palsy. Conclusion: Both TheraTogs and conventional physical therapy corrected foot pressure distribution, trunk control, improved balance, and increased 6MWD in children with spastic diplegic CP but the improvement was more significant in TheraTogs group. Clinical Trial Registration: NCT05271149.

Physical characterization of late-type contact binary systems observed by LAMOST: a comprehensive statistical analysis.

This paper presents a catalog of approximately 1800 Eclipsing W UMa systems (EWs) using parameters from LAMOST, VSX, ZTF and Gaia. Our detailed statistical analysis includes frequency distributions of parameters, confidence intervals, and hypothesis testing to provide deeper insights into the physical properties of this important eclipsing binary class. We focus on key parameters, including Period, Effective Temperature, Surface Gravity, metallicity, Radial Velocity, and spectral type of the systems. Our study reveals that the mean values for period, effective temperature, logarithmic surface gravity, metallicity, and radial velocity for EW systems are 0.377 days, 5775 K, 4, -0.185, and -4.085 km/s, respectively. The 95% confidence intervals for these parameters are 0.372 to 0.382 days, 5730 to 5820 K, -0.202 to -0.168, 3.97 to 4.03, and -6.47 to -1.7 km/s, respectively. Hypothesis testing of the estimated intervals results in the acceptance of the null hypothesis, indicating that EW systems are characterized within the specified limits. Our study also confirms that the majority of EW systems are late-type stars, primarily classified as F spectral type, followed by G and K. Interestingly, among the sample, 88 systems are classified as A spectral type, with a mean surface temperature of 7400 K. We examine the correlation between orbital periods and atmospheric parameters in the VSX and ZTF catalogs. While ZTF periods align well with established relations (correlation coefficient: 0.74), a weaker correlation is found in the VSX catalog. This highlights the need for a revision of VSX periods for improved accuracy in the studied sample of EWs.

The prevalence of diabetes distress among patients with type 2 diabetes in Jordan.

Objectives: Diabetes distress (DD) is a state of emotional distress that evolves from living with chronic disease and the burden of daily adjustments of medications and lifestyle. This study investigated the prevalence of DD in patients with type 2 diabetes mellitus (T2DM) in Jordan and the related sociodemographic and medical factors. Methods: We conducted a cross-sectional study in 608 patients with T2DM in Jordan, ranging from ages 15 to 80 years. The participants filled out a questionnaire where they were asked to self-assess their DD using the Diabetes Distress Scale. In all, 32 participants were excluded according to the exclusion criteria, which resulted in 576 people being included in this study. Results: The overall prevalence of DD was 53% (25% had moderate distress and 28% had high distress). Emotional distress had the highest prevalence among the DD subscales, with a total prevalence of 58.8%. The data showed a significant association of DD with different factors including age, the presence of diabetic complications, the type of medication used, and medication adherence. Conclusion: This study showed a high prevalence of DD (53%). This finding should raise awareness to healthcare providers about the importance of screening for DD as part of the treatment guidelines, especially in patients who are on multiple medication regimens for DM; patients who have previous medical complications related to DM; and those who exhibit poor adherence to medications, which was found to be a risk factor of DD in this study.

Relationship between Renal Function and Bone Mineral Density in Postmenopausal Women.

Renal insufficiency is a risk factor for osteoporosis and can increase risk of fracture. It may be a result of an age-related decline in renal function or chronic kidney disease. In patients with CKD, accurate diagnosis of osteoporosis or CKD-MBD is important for determining the most appropriate treatment. This was a cross sectional study was done at Institute of nuclear medicine and Allied Sciences, BSMMU, Dhaka from 1st January 2014 to 31st December 2014. Study population was total 69 postmenopausal women age over 50 years. Women with Bilateral hip replacement or bilateral hip pins or screws, metallic rods in spine, Carrying out BMD scan within the week after other radiological investigation using contrast media e.g. Barium meals or enema, IVPs were excluded from study. Clinical variables were- age (years), height (cm), weight (kg), BMI. Laboratory variables were- serum creatinine and BMD (Dexa). Estimated GFR was determined by using the serum Creatinine by MDRD formula. Renal function test and Bone mineral density (BMD) were done in all of these patients. Majority (43.4%) of the patients were in 6th decade. The mean weight was found 57.4±11.2kg. Majority 41(59.4%) patients belonged to T score at hip (-1 to -2.5) and their mean T score at hip was found (-1.1±1.1). Osteopenia and osteoporosis were found in 59.4% and 4.3% respectively according to BMD. High serum creatinine level was found in 10.1% cases. Renal function impairment was found in 79.6% of patient. Majority (50.7%) patients had mild decrease of eGFR (60-89 ml/min/1.73m²), There was Pearson's correlation (r=0.156; p=0.200) but not significant was found between age with T score at hip of the patients. Positive Pearson's correlation (r=0.112; p=0.361) was found but not significant between age and serum creatinine level. A significant negative Pearson's correlation (r= -0.274; p=0.023) was found between T score at hip and serum creatinine level of the patients. A significant negative Spearman correlation (r=-0.278; p=0.021) was found between BMD and serum creatinine of the patients. A significant positive Spearman correlation (r=0.580; p=0.001) was found between BMD and estimated GFR of the patients. This study was undertaken to evaluate the relationship between renal function and bone mineral density in postmenopausal women. Majority of the postmenopausal women were in 6th decade and most of them were overweight and obese. Renal function impairment was found in 79.6% of patient. Osteoporosis was found in 04.3% and 20.3% cases according to T score at hip and T score at lumber spine respectively. Significant negative Pearson's correlation was found between T score at hip and serum creatinine level of the patients. Significant negative Spearman correlation was found between BMD and serum creatinine of the patients. Significant positive Spearman correlation was found between BMD and estimated GFR of the patients.

Nasopharyngeal Carriage of Streptococcus pneumoniae Serotypes Among Healthy Children in Northern India.

Streptococcus pneumoniae (SP) infections cause morbidity and mortality among children worldwide. Hence India introduced 13-valent pneumococcal conjugate vaccine (PCV-13) in 2017 in a phased manner. The primary objective of this study was to assess the proportion of healthy children having nasopharyngeal colonization (NP) with SP. Secondary objective was to determine prevalent serotype of SP among the PCV13 vaccinated and non-vaccinated children. This cross-sectional study was conducted in 4 hospitals of Lucknow District, Northern India. Three hundred healthy children (2-59 months) were recruited between July and August 2019 from vaccination-clinics of hospitals. NP specimen was cultured using 5% sheep blood agar plate containing gentamicin. Pneumococcal isolates were identified by optochin sensitivity and bile-solubility tests. Serotyping was done using Quellung Method. Of the 300 healthy children, 56.7% (170/300) were males and 59.3% (181/300) had received at least one dose of PCV13 vaccine. The NP carriage rate of SP among healthy children was 37.7% (113/300). Vaccine serotypes were found in 33.3% (22/66) in PCV vaccinated children and 48.9% (23/47) in non-vaccinated children (p 0.09). Common vaccine serotypes that isolated were: 18C, 19A, 19F, 23F, 3, 4, 6A, 6B, 9 V. Thus more than one-third of healthy children had NP colonization with SP. Adjusting for age, there was a trend for significant reduction in vaccine serotypes in the NP with one doses versus two or more doses (ptrend = 0.04).

Task-evoked pupillary responses track precision-weighted prediction errors and learning rate during interceptive visuomotor actions.

In this study, we examined the relationship between physiological encoding of surprise and the learning of anticipatory eye movements. Active inference portrays perception and action as interconnected inference processes, driven by the imperative to minimise the surprise of sensory observations. To examine this characterisation of oculomotor learning during a hand-eye coordination task, we tested whether anticipatory eye movements were updated in accordance with Bayesian principles and whether trial-by-trial learning rates tracked pupil dilation as a marker of 'surprise'. Forty-four participants completed an interception task in immersive virtual reality that required them to hit bouncing balls that had either expected or unexpected bounce profiles. We recorded anticipatory eye movements known to index participants' beliefs about likely ball bounce trajectories. By fitting a hierarchical Bayesian inference model to the trial-wise trajectories of these predictive eye movements, we were able to estimate each individual's expectations about bounce trajectories, rates of belief updating, and precision-weighted prediction errors. We found that the task-evoked pupil response tracked prediction errors and learning rates but not beliefs about ball bounciness or environmental volatility. These findings are partially consistent with active inference accounts and shed light on how encoding of surprise may shape the control of action.

Clinical Profile and Immediate Outcome of Pyogenic Meningitis in Children.

Meningitis literally means inflammation of the meninges. It is mostly caused by bacteria, virus, fungus and protozoa and pyogenic meningitis constitutes a serious neurological disorder associated with significant morbidity and mortality in developing countries. This study was carried out to evaluate the clinical presentation and immediate outcome of pyogenic meningitis in children. This was a prospective observational study and conducted at department of Paeditrics in Cumilla Medical College Hospital, Cumilla, Bangladesh from July 2014 to June 2015. Total 50 children were diagnosed as pyogenic meningitis fulfilling the inclusion criteria was included in this study. Cases were enrolled purposively. Immediately after admission through history and clinical examination, complete blood count, random blood sugar, Cerebrospinal fluid (CSF) examination and blood culture was done in all patients. For statistical analysis chi-square test was done and significance of analysis was made when p value <0.05. This study includes patients aged between 2 months to 12 years and male female ratio was 1.5:1. Several risk factors like male sex (60.0%), age below one year (42.0%), Protein energy malnutrition (PEM) (30.0%), not exclusively breastfed (44.0%) were identified. Common presenting complaints were fever (100.0%), convulsion (96.0%), altered consciousness (42.0%) and vomiting (38.0%). Common physical signs were neck rigidity (56.0%), Kernig's sign (26.0%) and bulged fontanelle (34.0%). CSF was hazy in 54.0%, clear in 38.0% and turbid in 08.0% cases, CSF protein was more than 100mg/dl in 90.0% of the cases and glucose was less than 40mg/dl in most of the cases (94.0%). Streptococcus Pneumoniae (49.0%) followed by Neisseria Meningitidis (38.0%) were the two most commonly isolated organism responsible for pyogenic meningitis. Mortality rate during hospital stay was 18.0% and complications developed in 18.0% of cases. To avoid maltreatment in our resource limited setting due to failure of identifying organism, this study might help to administer appropriate antibiotics against organism and to reduce morbidity and mortality in meningitis. This study revealed less mortality rate in our country than neighbors and severe malnutrition important risk factors for the burden of pyogenic meningitis. It requires large scale multicentre studies to establish the whole scenario of Bangladesh.

Clinical Profile of Parkinson's Disease Patients in a Tertiary Hospital.

Parkinson's disease (PD) is the second most common neurodegenerative disorder after Alzheimer disease. The pathogenesis of PD is yet unknown. Aim of this study was to analyze the clinical profile of patient with early Parkinson disease. A total of seventy-six early Parkinson's disease patients were enrolled in this cross-sectional observational study which was carried out in the Department of Neurology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from September 2014 to March 2016. Analysis of the history and clinical findings were done among these patients. This study was performed with 76 early Parkinson disease patients. Among them, male and female were 69.7% and 30.3% respectively. The mean±SD age of patients was 53.25±11.53 years with an age range of 24 to 77 years. The patients were found in primary level accounted for 42.1% which was followed by secondary 19.7% and illiterate or non-formal education 17.1%. Only 5.3% study population was found in post-graduate. Occupant as 28.9% were service holder, 26.3% as a housewife, 1.3% as business and 43.5% other occupations. Regarding smoking, 28.9% was a current smoker, 59.2% non-smoker and 11.8% ex-smoker. Of them, 11.8% had a family history of Parkinson's disease. Of the total population, 30.3% had dyslipidemia, 21.1% had hypertension, and 7.9% had diabetes mellitus. Males are predominant in affecting this disease. Middle aged people are vulnerable to it. Parkinson's disease is common in nonsmoker and dyslipidaemia. Few patient had family history of Parkinson's disease.

Prevalence of intestinal nematodes infection in school children of urban areas of district Lower Dir, Pakistan.

Intestinal parasitism is the main cause of disease all over the world and described as a significant community health problem. The current study intended to find out the occurrence and identification of hazard factors linked with IPIs among 4-12 years aged shool-age children residing in Lower Dir district, Pakistan during 2019 - 2020. A cross-sectional school-based study was conducted using a pre-arranged pre-tested survey. Anthropometric data and stool collection were done to obtain the findings. The direct wet mount preparation in saline/iodine/methods was used for stool examination. Data were investigated using the GraphPad Prism 5. A total of 400 children studied (mean age of 8.6±3.6 years) the total incidence rate for the intestinal parasitic disease was established to be 71.75%. Of the 400 children studied, the overall prevalence rate for intestinal parasitic infections was found to 71.75% Ascaris lumbricoides (33.1%), Trichuris trichiura (1.04%), E. vermicularis (1.39%), Hookworm (19.86%) were identified in children living in the study area. We concluded that there is a mass scale campaigns were required to generate alertness about health and sanitation in children and the need for the development of effective poverty control programs because deworming (killing of worm with drugs) alone is not adequate to control parasitic infections.

New record of parasitic infection among school children of Lower Dir Pakistan.

Intestinal parasitic infections (IPIs) are a major cause of morbidity worldwide and have been described as an important public health problem. The present study aimed to determine the un usual parasitic infection and identification of risk factors among 4-12years old school age children residing in lower dir district, Pakistan from 2018- 2019. Of the 400 children studied in which the overall prevalence rate for intestinal parasitic infections was found to be 71.75%. Children infected with single parasite accounted for 67.94% and 32.05% were detected with poly-parasitism. Shistosoma japonicum (0.69%), Taxocara spp (0.69%) and cryptosporidium (0.69%), were identified in children living in studied areas. We conclude that there is a need for mass scale campaigns to create awareness regarding health and hygiene in children and the need for development of effective poverty control programmes.

Genetic and molecular analysis reveals that two major loci and their interaction confer clubroot resistance in canola introgressed from rutabaga.

Clubroot disease caused by Plasmodiophora brassicae is one of the serious threats to canola (Brassica napus L. subsp. napus) production. The evolution of new pathotypes rendering available resistances ineffective compel the introgression of new resistance into canola and extend our understanding of the genetic and molecular basis of the resistance. In this paper, we report the genetic and molecular basis of clubroot resistance in canola, introgressed from a rutabaga (B. napus L. subsp. rapifera Metzg. 'Polycross'), by using a doubled-haploid (DH) mapping population. Whole-genome resequencing (WGRS)-based bulked segregant analysis followed by genetic mapping and expression analysis of the genes in resistant and susceptible DH lines at 7 and 14 d after inoculation were carried out. Following this approach, two major quantitative trait loci (QTL) located at 14.41-15.44 Mb of A03 and at 9.96-11.09 Mb of A08 chromosomes and their interaction was observed to confer resistance to pathotypes 3H, 3A, and 3D. Analysis of the genes from the two QTL regions suggested that decreased expression of sugar transporter genes (BnaA03g29290D and BnaA03g29310D) may play an important role in resistance conferred by the A03 QTL, while increased expression of the toll/interleukin-1 receptor (TIR)-nucleotide binding (NB)-leucine rich repeat (LRR) (TNL) genes (BnaA08g10100D, BnaA08g09220D, and BnaA08g10540D) could be the major determinant of the resistance conferred by the A08 QTL. Single-nucleotide polymorphism (SNP) allele-specific polymerase chain reaction (PCR)-based markers, which could be detected by agarose gel electrophoresis, were also developed from the two QTL regions for use in breeding including pyramiding of multiple clubroot resistance genes.

Fagonia cretica: Identification of compounds in bioactive gradient high performance liquid chromatography fractions against multidrug resistant human gut pathogens.

Plants are alternative source of natural medicines due to secondary active metabolites. Fagonia cretica extracts and Gradient High-Pressure Liquid Chromatography fractionations were checked against multidrug-resistant gastrointestinal pathogens including, Salmonella typhi, Escherichia coli and Shigella flexneri. ESI-MS/MS analysis of bioactive HPLC fractions was performed to elucidate antibacterial compounds. F. cretica extracts exhibited potential antibacterial activity. Twenty-four (24) HPLC fractions were obtained from methanol, ethanol and aqueous extracts of F. cretica. Eighteen (18) fractions showed antibacterial activity, while no activity was observed by the remaining six (6) fractions. HPLC fractions, F1 (25g ± 0.20 mm) and F2 (15f ± 0.12 mm) of aqueous extract exhibited activity against multidrug resistant GI pathogens. Gallic acid, quinic acid, cyclo-l-leu-l-pro, vidalenolone, liquirtigenin, rosmarinic acid and cerebronic acid were identified in F1 fraction of aqueous extract, while succinic acid, cyclo (l-Leul-Pro) and liquirtigenin were identified in F2 fraction of aqueous extract through ESI-MS/MS analysis. F. cretica extracts and HPLC fractions showed potential activity against MDR GI pathogens. Vidalenolone, Cyclo-1-leu-1-pro and Cerebronic acid are first time reported in F. cretica. Further characterization of bioactive compounds from F. cretica may be helpful to elucidate antibacterial therapeutic molecules.

Diaphragmatic excursion by ultrasound: reference values for the normal population; a cross-sectional study in Egypt.

Background: Measurement of diaphragmatic motion by ultrasound is being utilized in different aspects of clinical practice. Defining reference values of the diaphragmatic excursion is important to identify those with diaphragmatic motion abnormalities. This study aimed to define the normal range of diaphragmatic motion (reference values) by Mmode ultrasound for the normal population. Methods: Healthy volunteers were included in this study. Those with comorbidities, skeletal deformity, acute or chronic respiratory illness were excluded. Diaphragmatic ultrasound in the supine position was performed using a lowfrequency probe. The B-mode was applied for diaphragmatic identification, and the M-mode was employed for the recording of the amplitude of diaphragm contraction during quiet breathing, deep breathing and sniffing. Results: The study included 757 healthy subjects [478 men (63.14%) and 279 women (36.86%)] with normal spirometry and negative history of previous or current respiratory illness. Their mean age and BMI were 45.17 ±14.84 years and 29.36±19.68 (kg/m2). The mean right hemidiaphragmatic excursion was 2.32±0.54, 5.54±1.26 and 2.90±0.63 for quiet breathing, deep breathing and sniffing, respectively, while the left hemidiaphragmatic excursion was 2.35±0.54, 5.30±1.21 and 2.97±0.56 cm for quiet breathing, deep breathing and sniffing, respectively. There was a statistically significant difference between right and left diaphragmatic excursion among all studied subjects. The ratio of right to left diaphragmatic excursion during quiet breathing was (1.009±0.19); maximum 181% and minimum 28%. Only 19 cases showed a right to left ratio of less than 50% (5 men and 14 women). The diaphragmatic excursion was higher in males than females. There was a significant difference in diaphragmatic excursion among age groups. Age, sex and BMI significantly affected the diaphragmatic motion. Conclusions: Diaphragmatic excursion values presented in this study can be used as reference values to detect diaphragmatic dysfunction in clinical practice. Diaphragmatic motion is affected by several factors including age, sex and body mass index.

Coronary Artery Occlusion during Transcatheter Aortic Valve Implantation: Early Recognition Have Better Outcome.

Transcatheter aortic valve implantation (TAVI) is one of the rapidly evolving treatment strategies for severe aortic stenosis. Included in this category are inoperable, high, intermediate, and low surgical risk patients. It has varying types of complications that may require urgent surgical or transcatheter interventions to prevent procedural mortality and morbidity. Coronary artery occlusion is a rare and dreaded complication of TAVI. Here, we report a 73-year-old man who was diagnosed with severe aortic stenosis and underwent transfemoral TAVI. Unfortunately, during preimplantation balloon valvuloplasty, the patient developed severe hypotension along with ischemic changes on the electrocardiographic monitor. Promptly, coronary angiography was performed which revealed complete occlusion of the left anterior descending artery secondary to embolic debris. He was successfully rescued by manual aspiration thrombectomy (MAT). MAT results in restoration of coronary flow and reversal of shock condition before completing TAVI procedure.

Diversity of rumen microbiota using metagenome sequencing and methane yield in Indian sheep fed on straw and concentrate diet.

An in vivo study aiming to investigate the rumen methanogens community structure was conducted in Mandya sheep fed on straw and concentrate diet. The ruminal fluid samples were collected and processed for unravelling the rumen microbiota and methanogens diversity. Further, the daily enteric methane emission and methane yield was also quantified using the SF6 tracer technique. Results indicated that the Bacteroidetes (∼57%) and Firmicutes (25%) were two prominent affiliates of the bacterial community. Archaea represented about 2.5% of the ruminal microbiota. Methanobacteriales affiliated methanogens were the most prevalent in sheep rumen. The study inveterate that the ruminal archaea community in sheep is composed of 9 genera and 18 species. Methanobrevibacter represented the largest genus of the archaeome, while methylotrophs genera constituted only 13% of the community. Methanobrevibacter gottschalkii was the prominent methanogen, and Methaobrevibacter ruminantium distributed at a lower frequency (∼2.5%). Among Methanomassiliicoccales, Group 12 sp. ISO4-H5 constituted the most considerable fraction (∼11%). KEGG reference pathway for methane metabolism indicated the formation of methane through hydrogenotrophic and methylotrophic pathways, whereas the acetoclastic pathway was not functional in sheep. The enteric methane emission and methane yield was 19.7 g/d and 20.8 g/kg DMI, respectively. Various species of Methanobrevibacter were differently correlated, and the distribution of hydrogenotrophic methanogens mainly explained the variability in methane yield between the individual sheep. It can be inferred from the study that the hydrogenotrophic methanogens dominate the rumen archaeal community in sheep and methylotrophic/aceticlastic methanogens represent a minor fraction of the community. Further studies are warranted for establishing the metabolic association between the prevalent hydrogenotrophs and methylotrophs to identify the key reaction for reducing methane emission.

Pattern of Tubercular Uveitis in Active Pulmonary Tuberculosis.

Ocular tuberculosis is an extra-pulmonary form of systemic Tuberculosis (TB). It is rarely found concomitant with active pulmonary tuberculosis (PTB). The aim of this prospective observational study was to evaluate the pattern of tubercular uveitis (TBU) in the patients with active PTB who attended in our Uvea clinic at NIO&H from July 2018 to December 2020. Active PTB patients who had uveitis consistent with TBU and TBU patients who were confirmed as active lung lesion were included in the study. Chest X-ray, TST, IGRA (QuantiFERON-TB Gold Test), RT PCR of aqueous fluid for tubercular bacillus, Gene Xpert TB test of sputum were done to confirm the diagnosis of ocular and primary TB. If the induration is 15 mm of TST was considered patient in this study. Among 33 patients of active PTB, 4 had TBU (12.12%). Among 48 patients of TBU, 5 had active PTB (10.41%). 13 eyes of 9 patients were affected. Mean age at presentation was 41.8 years. There were anterior uveitis in 23.00% eyes, posterior uveitis in 69% eyes and panuveitis in 7.00% eyes. Choroidal granuloma was the most common presentation of posterior uveitis (46.00%). There were more than 4 times chance to develop choroidal granuloma in patients with active PTB than extrapulmonary TB (Χ²=4.53, <0.05), TBU patients with choroidal granuloma should be evaluated meticulously for active PTB and active PTB patients should be evaluated routinely by ophthalmologist for the search of TBU.

Correlation Study between COPD and Heart Failure in Elderly Patient.

Heart failure and chronic obstructive pulmonary disease (COPD) are acquiring significant morbidity and mortality and the amalgamation presents many diagnostic challenges. Assessment of cardiac and pulmonary function by echocardiography and pulmonary function tests should be executed in all patients with cautious explanation to avoid misdiagnosis and wrong treatment. Both conditions share overlapping pathophysiological processes. Both functional status and quality of life are greatly influenced by these and associated with high morbidity and mortality rates leading to increase the health-care costs. Although both diseases have been studied extensively, information about the correlation between heart failure and COPD is lacking. Classifying the reason of breathing symptoms among people with both the diseases can be demanding. Therefore it is plausible that a considerable proportion of patients with a diagnosis of COPD have associated heart failure, which ruins unrecognized by primary care physicians or pulmonologists. This study's aim was to assess the relationship between chronic obstructive pulmonary disease and heart failure among elderly patients with chronic cough and dyspnea. This study was done in 100 patient's ≥40 years with a GP (general physician) diagnosis of COPD. Descriptive cross sectional study was carried out in the Department of Medicine, Shaheed Ziaur Rahman Medical College Hospital, Bogra, Bangladesh from November 2011 to April 2012. A total of 100 cases of chronic cough with breathlessness coming into out patient department and admitted into Department of Medicine of Shaheed Ziaur Rahman Medical College Hospital, Bogra, Bangladesh were included according to inclusion and exclusion criteria. Informed written consent was taken from the participants and data was collected by a questionnaire and relevant investigations were done. Data were analyzed with SPSS software and were expressed as mean±SE and significance level of differences among the group was calculated by unpaired student's 't' test. In this study among 100 participating patients with a diagnosis of COPD by their physician, in 24(24%) patients had previously unrecognized heart failure. Pearson Correlation study showed that there is significant positive correlation between FEV1/FVC and Left Ventricular Diastolic Dysfunction and there is also significant positive correlation between FEV1/FVC and Total Left Ventricular Dysfunction. By this study we recommend that evaluation and assessment of cardiac status is very important in elderly patients with COPD.

F. cretica extracts and HPLC fractions showed potential activity against MDR GI pathogens. Vidalenolone, Cyclo-1-leu-1-pro and Cerebronic acid are first time reported in F. cretica. Further characterization of bioactive compounds from F. cretica may be helpful to elucidate antibacterial therapeutic molecules.

Prevalence of cestodes infection among school children of urban parts of Lower Dir district, Pakistan / Prevalência de infecção de cestóides entre crianças em idade escolar de partes urbanas do distrito de Lower Dir, Paquistão

Tapeworms of zoonotic importance have been described as a leading public health problem. Current research was aim to assess the prevalence of tapeworms among 5-12years school children residing in district Lower Dir, Pakistan from January 2019-December 2019. The wet mount preparation in saline/iodine/methods were used for stool examination. Data was analyzed using appropriate descriptive, static methods. Of the 400 children studied 71.7% were infected with one or more species of intestinal parasites. Single infection of cestode species was found in 69 individuals with 17.2% prevalence and multiple parasitic infections were identified in 19.7% (n=79/400) individuals. The multiple infection were comprised as 10% (n=40) double, 6.75% (n=27) triple and 3% (n=12) quadruple. A total of 9 species of helminths and one species of protozoan infection. Among the helminths Ascaris lumbricoides was the most prevalent 33.1% (n=95), Taenia saginata 22.6% (n=65), hookworm 19.8% (n=57), Hymenolepis nana 18.8% (n=54), Enterobius vermicularis and Hymenolepis diminuta 1.39% (n=4each), Trichuris trichura 1.04% (n=3), Toxocara spp 0.69% (n=2) and Schistosoma japonicum 0.34% (n=1) were reported. One protozoan species was Cryptosporidium spp 0.69% (n=2) in current study. In case of A.lumbricoides, hookworm, E.vermicularis, T.trichura, T.saginata, H.nana and H.diminuta the male children of below 8 years of age were highly infected. Other infections are reported in the same prevalence with slight difference if any. We conclude that there is a need for mass scale campaigns to create awareness regarding health and hygiene in children and the need for development of effective poverty control programs because deworming alone is not adequate to control parasitic infections.

As tênias de importância zoonótica têm sido descritas como um dos principais problemas de saúde pública. A pesquisa atual teve como objetivo avaliar a prevalência de tênias entre crianças em idade escolar de 5 a 12 anos que residem no distrito de Lower Dir, Paquistão, de janeiro de 2019 a dezembro de 2019. Os métodos de preparação para montagem úmida em solução salina/iodo foram usados para exame de fezes. Os dados foram analisados usando métodos descritivos e estáticos apropriados. Das 400 crianças estudadas, 71,7% estavam infectadas com uma ou mais espécies de parasitas intestinais. Infecção única de espécies de cestóides foi encontrada em 69 indivíduos com prevalência de 17,2% e infecções parasitárias múltiplas foram identificadas em 19,7% (n = 79/400) indivíduos. As infecções múltiplas foram compostas por 10% (n = 40) dupla, 6,75% (n = 27) tripla e 3% (n = 12) quádrupla. Um total de 9 espécies de helmintos e uma espécie de infecção por protozoários. Entre os helmintos, Ascaris lumbricoides foi o mais prevalente 33,1% (n = 95), Taenia saginata 22,6% (n = 65), ancilóstomo 19,8% (n = 57), Hymenolepis nana 18,8% (n = 54), Enterobius vermicularis e Hymenolepis diminuta 1,39% (n = 4cada), Trichuris trichura 1,04% (n = 3), Toxocara spp 0,69% (n = 2) e Schistosoma japonicum 0,34% (n = 1). Uma espécie de protozoário foi Cryptosporidium spp 0,69% (n = 2) no estudo atual. No caso de A. lumbricoides, ancilostomíase, E. vermicularis, T. trichura, T. saginata, H. nana e H. diminuta, as crianças do sexo masculino com menos de 8 anos de idade estavam altamente infectadas. Outras infecções são relatadas na mesma prevalência, com ligeira diferença, se houver. Concluímos que há uma necessidade de campanhas em massa para criar consciência sobre saúde e higiene em crianças e a necessidade de desenvolvimento de programas eficazes de controle da pobreza, porque a desparasitação por si só não é adequada para controlar infecções parasitárias.
