Effect of Achyranthes japonica extract on growth, digestibility, microbiota, gas emission, and meat quality in broilers fed different protein diets.

Achyranthes japonica extract (AJE) is a multifuctional products that express anti-inflammatory, antioxidant and anti-microbial properties. This study was aimed to evaluate the effects of AJE addition to standard and low crude protein (LCP) diet on growth performance, nutrient digestibility, excreta bacterial count, excreta noxious gas emissions, breast meat quality, and organ weight of broiler chicken. A total of 340 one-day-old Ross 308 broilers [initial body weight (BW) of 43.10 ± 1.46 g, 5 replicate cages per treatment, and 17 birds per cage] were randomly distributed into 1 of 4 dietary treatment groups for a 35 day trial. The diets were provided based on three age stage of the broiler. In the starter stage broiler were fed basal diet. Experimental diet were fed to broiler from day 8 to 35. In growing (days 8-21) and finishing (days 22-35) stage broiler were fed: Standard crude protein (SCP) diet and LCP diet with 0.025% and 0.05% of AJE supplementation respectively. Here, the SCP and LCP diets were 21.50% and 20.86% CP during days 8-21 and 20.00% and 19.40% CP during days 22-35, respectively. The SCP diets with 0.025% AJE supplementation resulted in higher (p < 0.5) BW gain (BWG) at finishing stage and a tendency to lower feed conversion ratio and BWG in the overall period compared to LCP diets with or without AJE supplemenation. Moreover, dry matter and nitrogen digestibility were increased with SCP diet along with 0.025% of AJE. No significant difference was found in meat quality parameters except for pH. Interestingly, the NH3 gas emission to the environment was found to be less with different levels of CP and AJE supplementation. Therefore, we concluded that the addition of 0.025% AJE to the SCP diet improved broiler growth performance and nutrient digestibility with low fecal NH3 emissions.

Dietary inclusion of micelle silymarin enhances egg production, quality, and lowers blood cholesterol in Hy-line brown laying hens.

This study aimed to evaluate the effect of micelle silymarin (MS) supplementation on productive performance, egg quality, and blood biochemical parameters in laying hens. A total of 384 (Hy-Line brown, 28-week-old) laying hens were randomly distributed into one of four dietary treatment groups (eight replication per treatment; 12 hens per replicate) for a 12-week long feeding trial. Hens were fed a basal diet with the addition of 0%, 0.02%, 0.04%, and 0.06% of MS respectively. The results expressed that egg production percentage and egg weight were linearly (p < 0.05) enhanced at Weeks 0-6, 7-12, and 0-12, when 0%, 0.02%, 0.04%, and 0.06% of MS were added to laying hen diets. The feed conversion ratio and feed intake improved (p < 0.05) linearly at Weeks 0-6, 7-12, and 0-12 with increasing levels of MS supplementation in laying hens. The eggshell thickness and eggshell strength were linearly (p < 0.05) improved at weeks 4, 8, and 12 with an MS-supplemented diet. Additionally, eggshell colour, Haugh unit, and albumin height had no significant (p > 0.05) difference throughout the experimental period with different levels of MS-supplemented diet. The yolk colour of eggs showed significant (p < 0.05) differences at weeks 8 and 12 with levels of the MS-supplemented diet. However, at the end of the trial, the blood profile indicated that cholesterol levels decreased (p < 0.05) linearly, and triglyceride levels showed a tendency to decrease (p < 0.10) with MS supplementation. In conclusion, increasing the level of MS addition in the laying hen diet improved the egg production percentage and egg quality, reducing cholesterol levels in Hy-Line brown hens. However, this study indicates that MS can be added to the diet of laying hens up to 0.06% for improved egg production and egg quality.

Elevated Troponin I as a Marker for Unfavorable Outcomes in Acute Ischemic Stroke.

OBJECTIVE: To assess if elevated cardiac troponin I (cTnI) serves as a sign of unfavorable functional outcomes in ischemic stroke. METHODS: In this single-center prospective cohort study, 100 consecutive patients admitted with acute ischemic stroke (normal troponin I group n = 52, raised troponin I group n = 48) were included. Hospital mortality was documented in both groups; the remaining patients were followed up to 90 days. Then two groups were compared in terms of unfavorable short-term outcomes (Modified Rankin Scale > 3) and mortality. Multivariate logistic regression was conducted to determine the predictive value of elevated cTnI. The Kaplan-Meier curve was drawn and compared to determine the difference in survival between the two groups. To find out the most probable cut-off level for an unfavorable outcome, a receiver operating characteristic (ROC) analysis was conducted. RESULT:  A higher frequency of coronary artery disease (p=0.030), higher National Institutes of Health Stroke Scale (NIHSS) (p=0.008) score, and lower Glasgow Coma Scale (GCS) (p=0.002) was observed in raised troponin I group. Even after the exclusion of confounding elevated troponin I was found to be an independent predictor of unfavorable outcomes (adjusted odds ratio, OR 8.25 {95% confidence interval, CI: 2.65-25.75}; p<0.001). The patients with raised troponin I had a significantly lower rate of survival after 90 days (p=0.022). The elevated troponin I was observed to have a significantly high accuracy (p<0.001; area under curve, AUC: 0.768 {moderate accuracy}, 95% CI: 0 .676 to 0.861) in predicting unfavorable outcomes. CONCLUSION: Elevated cTnI is independently associated with unfavorable short-term outcomes. It is also associated with a lower rate of survival.

Effectiveness of a Health Education Program for Patients Who Had a Stroke and Their Caregivers by Controlling Modifiable Risk Factors to Reduce Stroke Recurrence in a Tertiary Hospital in Bangladesh: Protocol for a Randomized Controlled Trial.

BACKGROUND: Stroke is a significant public health concern that causes severe and long-lasting disability. The recurrence of stroke is increasing due to lack of patients' knowledge and compliance with treatment to control modifiable risk factors and lifestyle changes. Health education can be an effective way to increase knowledge about behavioral changes in patients who had a stroke. OBJECTIVE: The aim of this study is to evaluate the effectiveness of a health education program in Bangladesh for patients who had their first stroke and their family caregivers in order to reduce the recurrence of stroke by controlling modifiable risk factors. METHODS: This is a parallel, open-label, prospective randomized controlled trial conducted at the National Institute of Neurosciences & Hospital in Dhaka, Bangladesh. We enrolled ≥18-year-old patients of both sexes who had a history of first stroke attack (transient ischemic attack, hemorrhagic stroke, lacunar stroke, atherothrombotic stroke, or cardioembolic stroke). We stratified patients into those aged <65 years and those aged ≥65 years and according to types of strokes for randomization. Our estimated sample size was 432. The intervention group receives face-to-face counseling on lifestyle modifications, blood pressure monitoring, and medication compliance-related health education during enrollment and monthly follow-ups. However, the control group receives only usual care from the hospital. The primary end point of this study is the reduction in the stroke recurrence rates at the end of the 12-month follow-up period. The secondary end points are to (1) assess the occurrence of all adverse events such as other cardiac events and all-cause mortality, (2) evaluate the status of the controlling modifiable risk factors such as blood pressure, glycated hemoglobin, and non-high-density lipoprotein cholesterol, (3) assess the knowledge related to stroke by using the investigator-developed questionnaire, (4) evaluate the lifestyle behavior related to stroke by using the investigator-developed questionnaire, (5) assess medication adherence, and (6) evaluate the quality of life of patients who had a stroke and their family caregivers. The evaluation points will be at baseline, 6 months, and 12 months for both groups. RESULTS: Patients' enrollment started on October 2022, and follow-up will be completed in March 2024. A total of 432 participants were included in both the intervention (n=216) and control groups (n=216). This study was approved by the institutional review board and the ethics review board of the National Institute of Neurosciences & Hospital (IRB/NINSH/2022/151) on August 30, 2022. CONCLUSIONS: Our health education program is expected to reduce the recurrence of stroke and improve the quality of life of patients who have had the first stroke. The results of this study will provide insights into the importance of health education for (self)-management and prevention of stroke.

Open-label, phase 2 study of blinatumomab after frontline R-chemotherapy in adults with newly diagnosed, high-risk DLBCL.

This open-label, multicenter, single-arm, phase 2 study assessed the safety and efficacy of blinatumomab consolidation therapy in adult patients with newly diagnosed, high-risk diffuse large B-cell lymphoma (DLBCL; International Prognostic Index 3-5 and/or double-/triple-hit or double MYC/BCL-2 expressors) who achieved complete response (CR), partial response (PR), or stable disease (SD) following run-in with 6 cycles of R-chemotherapy (NCT03023878). Of the 47 patients enrolled, 28 received blinatumomab. Five patients (17.9%) experienced grade 4 treatment-emergent adverse events of interest (neutropenia, n = 4; infection, n = 1). Two deaths reported at the end of the study were unrelated to treatment with blinatumomab (disease progression, n = 1; infection, n = 1). 3/4 patients with PR and 4/4 patients with SD after R-chemotherapy achieved CR following blinatumomab. Consolidation with blinatumomab in patients with newly diagnosed, high-risk DLBCL who did not progress under R-chemotherapy was better tolerated than in previous studies where blinatumomab was used for treatment of patients with lymphoma.

A Community Audit of 300 "Drop-Out" Instances in Children Undergoing Ponseti Clubfoot Care in Bangladesh-What Do the Parents Say?

Introduction: Drop-out before treatment completion is a vexing problem for all clubfoot clinics. We and others have previously identified better engagement with parents as a crucial method of ameliorating incomplete clubfoot treatment, which increases deformity relapse. Materials and methods: The novel use of community facilitators enabled an audit of over 300 families who had dropped-out from a child's clubfoot treatment. A questionnaire standardized the parent interviews. Parents were encouraged to present for clinical review of their child's clubfeet. Results: When treatment was discontinued for six months, 309 families were audited. A social profile of families was developed, showing that most lived in tin houses with one working family member, indicating low affluence. Family issues, brace difficulty, travel distances, and insufficient understanding of ongoing bracing and follow-up were the main reasons for discontinuing treatment. Overt deformity relapse was found in 9% of children, while half of the children recommenced brace use after review. Conclusions: Identifying families at risk of dropping out from clubfoot care enables support to be instigated. Our findings encourage clinicians to empathize with parents of children with clubfoot deformity. The parent load indicator, in parallel with the initial clubfoot severity assessment, may help clinicians to better appreciate the demand that treatment will place on parents, the associated risk of drop-out, and the opportunity to enlist support.

PDMS Gasket Underfill for Long-Term Insulation of High-Density Interconnections in Active Implantable Medical Devices.

This work presents reliability investigations of silicone gasket as solid underfill for interconnection interfaces in hybrid implant systems with high channel count flexible electrode arrays and hermetically packed electronics. The gasket is fabricated by laser structuring thin sheet of silicone rubber. The surface activation of silicone sheet ensures mechanical bonds with the mating surfaces thereby improving the mechanical stability of the assembly and the insulation of the interconnects. The gasket samples with $10 \times 10$ openings for interconnect pads, each with diameter of $270 \mu \mathrm {m}$ and a center to center pitch size of $490 \mu \mathrm {m}$, were sandwiched between a polyimide array and a metallized ceramic substrate. The gasket maintained high insulation impedance of $15 \pm 0.30 \mathrm {M}\Omega $ between the adjacent interconnects with markedly capacitive behavior (phase angle, $- 89 ^{\circ})$ after 17 weeks in soaked conditions under accelerated aging at $60 ^{\circ}\mathrm {C}$. The gasket also survived electrical stresses and sustained high impedance $(10.93 \mathrm {M}\Omega $ with phase angle of $- 88 ^{\circ})$ when subjected to constant 3 VDC for 100 days.

The effect of different organic solvents on sodium ion storage in carbon nanopores.

In this study fully atomistic grand canonical Monte Carlo (GCMC) simulations have been employed to study the behaviour of an electrolyte salt (NaPF6) and different non-aqueous (organic) solvents in carbon nanopores, to reveal the structure and storage mechanism. Organic solutions of Na+ and PF6- ions at 1 M concentration were considered, based on the conditions in operational sodium ion batteries and supercapacitors. Three organic solvents with different properties were selected: ethylene carbonate (EC), propylene carbonate (PC), and ethyl methyl carbonate (EMC). The effects of solvents, pore size and surface charge were quantified by calculating the radial distribution functions and ionic density profiles. It is shown that the organic solvent properties and nanopore confinement can affect the structure of the organic electrolyte solution. For the pore size range (1-5 nm) investigated in this paper, the surface charge used in this study can alter the sodium ions but not the solvent structure inside the pore.

Clinical and morphological pattern of brain arteriovenous malformations (BAVMs) in a tertiary care hospital in Bangladesh.

BACKGROUND: We have conducted this study to examine the clinical and morphological pattern of brain arteriovenous malformations (BAVMs) along with their treatment and short term outcome in a tertiary care hospital in Bangladesh. This retrospective chart review was carried out from the records of neuro-endovascular division at Department of Neurology, Dhaka Medical College Hospital (DMCH) from January 2010 to June 2013. A total 60 patients were evaluated. All the necessary information regarding the demographic, clinical, morphologic and treatment profile was gathered through a predesigned questionnaire. To our knowledge, we have the largest cohort of BAVM patients in Bangladesh and this is the first of this kind of study done in Bangladesh. RESULTS: The mean age at diagnosis was 30.3 years with a standard deviation of ±14.3 and the majority was teenagers (30%). Intracerebral hemorrhage was the commonest (70%) type of presentation at diagnosis, followed by headache (50%), altered consciousness (50%), vomiting (40%) and seizure (40%). Majority of the AVMs had feeders from anterior circulation (50%) and most of the AVMs (73.3%) were supplied from the main feeders, whereas the rest from distal vessels. Regarding venous drainage, AVMs drained mostly either to superficial (43.3%) or deep (40%) venous system. AVMs frequently had larger (40%) nidus size and a slow to medium flow (60%), through the nidus. An eloquent AVM location was found in 50% of the patients. Intranidal aneurysm was found in 10% AVM and angiopathic AVM in 13.3%. Patients were treated by endovascular embolization (31) or surgical excision (11) or conservative approach. There was one event of death, both in embolization group and surgically treated group before discharge. The patients were followed up for 1.3 ± 0.8 years. The rate of rebleed was 6.6, 30 and 60% during follow up in endovascular, surgical and conservatively treated group. Though five patients in conservative group died during this time, no deaths reported in intervention group (endovascular or surgery). CONCLUSION: Intracerebral hemorrhages, headache, altered consciousness and seizure are common clinical presentations of AVM at diagnosis. The remarkable morphologic features are larger AVM size at eloquent location, medium to slow flow with frequent feeders from main vessels of anterior circulation and drainage to superficial venous systems. Endovascular embolization or surgical excision of AVM are relatively safe and effective and provides better short term outcome than conservative approach.

Antiepileptic drug utilization in Bangladesh: experience from Dhaka Medical College Hospital.

BACKGROUND: Epilepsy is a common health problem which carries a huge medical social psychological and economic impact for a developing country. The aim of this hospital-based study was to get an insight into the effectiveness and tolerability of low cost antiepileptic drugs (AEDs) in Bangladeshi people with epilepsy. METHODS: This retrospective chart review was done from hospital records in weekly Epilepsy outdoor clinic of Department of Neurology, Dhaka Medical College Hospital (DMCH) from October 1998 to February 2013. A total of 854 epilepsy patients met the eligibility criteria (had a complete record of two years of follow up data) from hospital database. A checklist was used to take demographics (age and gender), epilepsy treatment and adverse event related data. At least two years of follow up data were considered for analysis. RESULTS: Out of 854 patients selected, majority of the patients attending outdoor clinic were >11-30 years age group (55.2%) with a mean age of 20.3 ± 9 years and with a male (53%) predominance. Focal epilepsy were more common (53%), among whom secondary generalized epilepsy was the most frequent diagnosis (67%) followed by complex partial seizure (21%). Among those with Idiopathic Generalized Epilepsy (46%), generalized tonic clonic seizure was encountered in 74% and absence seizure was observed in 13%. The number of patients on monotherapy and dual AED therapy were 67% and 24% respectively and polytherapy (i.e. >3 AEDs) was used only in 9%. CBZ (67%) was the most frequently prescribed AED, followed by VPA (43%), PHB (17%), and PHT (8%). CBZ was prescribed in 37% patients as monotherapy followed by VPA in 21% and PHB in 8% patients. Newer generation drugs eg lemotrigine and topiramate were used only as add on therapy in combination with CBZ and VPA in only 2% patients. The treatment retention rates over the follow up period for the AEDs in monotherapy varied between 86 and 91% and were highest for CBZ, followed by VPA. Most of the combination regimens had a treatment retention rate of 100%. The effectiveness of AED in terms of reduction of seizure frequency was highest for PHT (100%) and PHB (98%) followed by CBZ (96%) and VPA (95%). PHB and PHT were the cheapest of all AEDs (42 I$ and 56 I$/ year respectively). The costs of VPA and CBZ were two times and LTG and TOP were six to eight times higher. Adverse drug reaction (ADR) were observed among 140 (24.5%) of those with monotherapy. PHT (64%) was the most common drug to cause ADR, CBZ was at the bottom of the list to cause adverse effect (11.6%). VPA and PHB caused weight gain commonly. Adjustment of drug dose or withdrawal due to ADRs was necessary in 39% with PHT and 26% with PHB. CONCLUSION: Though PHT and PHB are cheapest and efficacious among all, CBZ and VPA are less costly, effective and well tolerated drug for seizure control in context of Bangladesh.

Pattern of headache in school going children attending specialized clinic in a tertiary care hospital in bangladesh.

OBJECTIVE: To determine the pattern of headache and its associated symptoms in school going children. METHODS: The data of all the school going children attending the Headache Clinic in the Dept. of Neurology, Dhaka Medical College Hospital were retrospectively reviewed. A total of 1021 patients from October 1996 to September 2011 were selected. Data were collected through a predesigned questionnaire containing information on age, sex, social status, clinical features, opthalmoscopic findings, management, and in selected cases imaging results. RESULT: The mean age of headache in school children was 12.6±1.08 years with relatively older age of presentation among girls. The sex ratio was 1.64:1 in favor of girls at older age. Tension type headache (71.1%) was the most common form of headache, followed by migraine (18.4%) and mixed headache (6.7%). Though the girls had more frequent headache of both tension type (59.4%) and migraine (68.1%) variety, the latter was significantly associated in girls (p<0.001). Headache was of moderate severity in 53.3%, whereas severe headache was experienced by 19.9% of the children. The children commonly had nausea and/or vomiting (47.2%), as well as photophobia (24.7%) with headache. Mental stress (34%) and sunlight (30.9%) were common triggering factors whereas a sound sleep relieved headache in the majority (59.4%). Paracetamol (83.3%) and nortryptyline (62.8%) were the most commonly prescribed drug taken by them. CONCLUSION: Headache is a major health problem in school children, apart from other common health issues at this age. With increasing age, the girls more commonly suffer not only from migraine but also with other chronic headache. The direct causal association is yet to be determined.

Precipitating and relieving factors of migraine versus tension type headache.

BACKGROUND: To determine the differences of precipitating and relieving factors between migraine and tension type headache. METHODS: This is a cross sectional study. We retrospectively reviewed the records of 250 migraine patients and 250 patients diagnosed as tension type headache from the specialized headache clinic in Dept. of Neurology, Dhaka Medical College Hospital. Data were collected through a predesigned questionnaire containing information on age, sex, social status and a predetermined list of precipitating and relieving factors. RESULTS: In this study, the female patients predominated (67%). Most of the patients were within 21-30 years age group (58.6%). About 58% of them belonged to middle class families. The common precipitating factors like stress, anxiety, activity, journey, reading, cold and warm were well distributed among both the migraine and tension type headache (TTH) patients. But significant difference was demonstrated for fatigue (p < 0.05), sleep deprivation (p < 0.05), sunlight (p < 0.01) and food (p < 0.05), which were common among migraineurs. In consideration of relieving factors of pain, different maneuvers were commonly tried by migraineurs and significant difference were observed for both analgesic drug and massage (p < 0.05), which relieved migraine headache. But maneuvers like sleep, rest and posture were used by both groups. CONCLUSION: The most frequent precipitating factors for headache appear to be identical for both migraine and TTH patients. Even though some factors like fatigue, sleep deprivation, sunlight and food significantly precipitate migraine and drug, massage are effective maneuver for relieving pain among migrianeurs.

Association of intussusception and celiac disease in adults.

INTRODUCTION: Intussusception (IS) is rare in adults. However, the more frequent use of cross-sectional imaging has resulted in an increase in its detection. Because of the reported association with celiac disease, we determined the prevalence of IS among a cohort with celiac disease. METHODS: An anonymized prospectively maintained celiac disease database and radiological database were reviewed. RESULTS: Of a total of 880 patients, 14 (age 47 ± 17.5 years; 50% female) had IS that was detected by CT in 10, capsule endoscopy in three, and barium studies in two. The reason for evaluation was abdominal pain in 78% (11/14), whereas in the remainder (3/14) were incidental. IS was the initial manifestation of celiac disease in 57% (8/14). Two patients were found to have lead-point intussusceptions and both had small-bowel adenocarcinoma, and 10/14 had severe villous atrophy (subtotal or total). Among those with established celiac disease, IS was detected early, within 3 years of diagnosis. Follow-up was available for 11 patients, 9 of who adhered strictly to a gluten-free diet, and six had no recurrence. Among all the patients diagnosed with IS on radiologic studies at our institution, 45 were considered to have idiopathic IS. Only two of these patients had evaluation for celiac disease. CONCLUSION: IS occurs in celiac disease. It may be the initial presentation and is associated with abdominal pain. Adenocarcinoma needs to be excluded. The majority of patients do not have recurrent symptoms after adherence to a gluten-free diet. Celiac disease should be considered more frequently when IS is encountered.

Primary hepatic lymphoma presenting as fulminant hepatic failure with hyperferritinemia: a case report.

INTRODUCTION: Primary hepatic lymphoma is an unusual form of non-Hodgkin's lymphoma that usually presents with constitutional symptoms, hepatomegaly and signs of cholestatic jaundice. Diffuse hepatic infiltration is uncommon and presentation with acute hepatic failure even more rare. The presence of markedly elevated ferritin levels can complicate the evaluation process and suggest alternative diagnoses.We present the case of a middle-aged woman exhibiting pancytopenia, hyperferritinemia and rapidly deteriorating to develop acute hepatic failure. Her initial clinical picture led to a working diagnosis of adult onset Still's disease with probable hemophagocytic syndrome before her worsening liver function necessitated a percutaneous liver biopsy and establishment of the final diagnosis of primary hepatic lymphoma. CONCLUSION: Primary hepatic lymphoma is an uncommon malignancy and its manifestation as progressive hepatitis or acute fulminant hepatic failure can be difficult to diagnose. The presence of constitutional symptoms, pancytopenia and high ferritin levels can complicate the evaluation process. A liver biopsy early in the course of liver dysfunction may establish the diagnosis without a higher risk of bleeding complications seen once liver failure sets in.
