Impact of nitrogen and phosphorus fertilizers on Cry1Ac protein contents in transgenic cotton / Impacto de fertilizantes de nitrogênio e fósforo nos conteúdos de proteína Cry1Ac em algodão transgênico

Application of different fertilizers to check the efficiency of expression of Bt (Bacillus thuringiensis) gene in one of the leading commercialized crops (cotton) against Lepidopteran species is of great concern. The expression of Cry protein level can be controlled by the improvement of nutrients levels. Therefore, the myth of response of Cry toxin to different combinations of NP fertilizers was explored in three Bt cotton cultivars. Combinations include three levels of nitrogen and three levels of phosphorus fertilizers. Immunostrips and Cry gene(s) specific primer based PCR (Polymerase Chain Reaction) analysis were used for the presence of Bt gene that unveiled the presence of Cry1Ac gene only. Further, the ELISA (enzyme-linked immunosorbent assay) kit was used to quantify the expression of Cry1Ac protein. Under various NP fertilizers rates, the level of toxin protein exhibited highly significant differences. The highest toxin level mean was found to be 2.3740 and 2.1732 µg/g under the treatment of N150P75 kg ha-¹ combination while the lowest toxin level mean was found to be 0.9158 and 0.7641 µg/g at the N50P25 kg ha-¹ level at 80 and 120 DAS (Days After Sowing), respectively. It was concluded from the research that the usage of NP fertilizers has a positive relation with the expression of Cry1Ac toxin in Bt cotton. We recommend using the N150P50 kg ha-1 level as the most economical and practicable fertilizer instead of the standard dose N100P50 kg ha-¹ to get the desired level of Cry1Ac level for long lasting plant resistance (<1.5). The revised dose of fertilizer may help farmers to avoid the cross-resistance development in contradiction of insect pests.

A aplicação de diferentes fertilizantes para verificar a eficiência da expressão do gene Bt (Bacillus thuringiensis) em uma das principais culturas comercializadas (algodão) contra espécies de lepidópteros é uma grande preocupação. A expressão do nível de proteína Cry pode ser controlada pela melhoria dos níveis de nutrientes. Portanto, o mito da resposta da toxina Cry a diferentes combinações de fertilizantes NP foi explorado em três cultivares de algodão Bt. As combinações incluem três níveis de nitrogênio e três níveis de fertilizantes de fósforo. A análise de PCR (reação em cadeia da polimerase) específica para o gene (s) Immunostrips e Cry (s) foi usada para a presença do gene Bt que revelou a presença do gene Cry1Ac apenas. Além disso, o kit ELISA (ensaio de imunoabsorção enzimática) foi usado para quantificar a expressão da proteína Cry1Ac. Sob várias taxas de fertilizantes NP, o nível de proteína de toxina exibiu diferenças altamente significativas. A média do nível mais alto de toxina foi de 2,3740 e 2,1732 µg / g sob o tratamento da combinação N150P75 kg ha-¹, enquanto a média do nível mais baixo de toxina foi de 0,9158 e 0,7641 µg / g no nível de N50P25 kg ha-¹ em 80 e 120 DAS (dias após a semeadura), respectivamente. Concluiu-se com a pesquisa que o uso de fertilizantes NP tem relação positiva com a expressão da toxina Cry1Ac no algodão Bt. Recomendamos o uso do nível de N150P50 kg ha-¹ como o fertilizante mais econômico e praticável em vez da dose padrão N100P50 kg ha-¹ para obter o nível desejado de nível de Cry1Ac para resistência de planta de longa duração (<1,5). A dose revisada de fertilizante pode ajudar os agricultores a evitar o desenvolvimento de resistência cruzada em contradição com as pragas de insetos.

Ultrasound-guided transversalis fascia plane block versus transmuscular quadratus lumborum block for post-operative analgesia in inguinal hernia repair

Background@#Inguinal hernia repair is one of the most commonly performed surgical procedures. Regional blocks might provide excellent analgesia and reduce complications in the postoperative period. We aimed to compare the postoperative analgesic effect of the ultrasound-guided transversalis fascia (TF) plane block versus the transmuscular quadratus lumborum (QL) block in patients undergoing unilateral inguinal hernia repair. @*Methods@#Fifty patients enrolled in this comparative study and were randomly assigned into two equal groups. One group received an ultrasound-guided QL block.In comparison, the other group received an ultrasound-guided TF plane block. The primary outcome was the patient-assessed resting, and movement-induced pain on the numeric pain rating scale (NRS) measured at 30 minutes postoperatively. Secondary outcomes included the percentage of patients receiving rescue analgesia in the first postoperative day, ease of performance of the technique, and incidence of adverse effects. @*Results@#There were no statistically significant differences in NRS at rest and with movement between the groups over the first 24 hours postoperatively. The proportion of patients that received postoperative rescue analgesics during the first 30 minutes postoperatively was 4% (n = 1) in the QL group compared to 12% (n = 3) in the TF group. However, the mean performance time of the TF block was shorter than that of the QL block, and the performance of the TF block appeared easier technically. @*Conclusions@#The ultrasound-guided TF plane block could be as effective as the QL block in lowering pain scores and decreasing opioid consumption following nonrecurrent inguinal herniorrhaphy.

ICH Score and Basal Plasma D-Dimer in Patients with Intracerebral Haemorrhage

Intracerebral haemorrhage constitutes 10-20 % of all strokes & remains without treatment of proven benefit & has higher risk of morbidity & mortality than cerebral infarction or subarachnoid bleed. Thus, these models may accurately predict outcome, and hence the purpose of this study is to define a clinical grading scale for patients with ICH which uses criteria that are predictive of outcome & that can be rapidly & accurately assessed at the time of presentation in emergency/casualty. Estimation of basal plasma D-dimer levels an indicator of systemic activation of coagulative & fibrinolytic system has shown to a powerful predictor of both early neurological worsening & mortality outcome & hence the present study is undertaken.METHODSThe study was carried out in the IPD of Department of General Medicine, Basaveshwara Teaching and General Hospital, Kalaburagi, attached to Mahadevappa Rampure Medical College. It is a cross sectional study conducted among 100 intracerebral bleed patients between November 2018 to November 2019 with simple random sampling procedure. Patients were followed up at the end of 1 month with telephone/letter/email.RESULTSThe mortality among patients who scored 0 of ICH scale was 0%, ICH score of 1 was 13.6 %, ICH score of 5 was 100 %. No patient scored 6. Higher the ICH score, higher is the mortality. Mortality among patients with D-Dimer value between 1500 – 5000 ng/ml is 55.2 %, and > 5000 ng/ml is 92.3 %. Above table indicates that higher the basal level of D-Dimer value higher is the mortality. Mortality among patients of either sex was equal i.e., 50 % between 8 - 15 days, and no deaths were noted between 15 - 30 days.CONCLUSIONSIntracerebral haemorrhage (ICH) has remained a serious disease despite recent improvements in management. So, efforts must be directed towards better understanding and modification of risk factors. The major risk factor in our study was hypertension. The other common risk factors were alcohol consumption and smoking. Thus, measures to ensure adequate control of hypertension/compliance of treatment among hypertensive, abstinence from alcohol and smoking may reduce the incidence of ICH. High initial plasma D-Dimer levels would indicate bad prognosis in ICH. In addition to diagnosis of ICH, CT Scan can also be used as a useful tool in assessing prognostic outcome of ICH, by using radiological parameters like larger volume of haematoma, presence of midline shift, intraventricular extension of haemorrhage and hydrocephalus which indicated bad prognosis i.e., using ICH score, higher the ICH score higher is the mortality.

Clinical Profile of Snake Envenomation with Complications and Outcome in a Tertiary Health Care Centre, Kalburgi.

Bites by snakes represent an important health problem in the tropical world including India. The true incidence of snakebites is difficult to assess and often is under reported. Though the exact number of snake bites is unknown, an estimated 5.4 million people are bitten each year with up to 2.7 million envenoming. Around 81,000 to 1,38,000 people die each year because of snake bites, and around three times as many amputations and other permanent disabilities are caused by snakebites annually. We wanted to determine frequency of various modes of presentation, complications and management of snakebite.METHODSAll patients presenting to emergency department of Basaveshwara Teaching and General Hospital with history of snakebite and features of envenomation were included in the study. All these patients were given Anti-Snake Venom. Symptomatic treatment of complications was done. Semi-structured questionnaire was filled during hospital stay to analyse various characteristics of snakebite and people’s attitude towards this problem.RESULTS75 cases of snakebite admitted to Basaveshwara Teaching & General Hospital, Gulbarga between January 2018 to November 2019 were studied. Males [50 (62.5%)] were affected more than females [25 (31.5%)] in the ratio of 2:1. Most common age group is 20-40 years [45 (60%)]. Snakebite is a common health hazard in rural areas [55 (73.34%)]. Agricultural labourers (68.6%) are the major sufferers with majority of bites occurring outdoor 60 (80%). 71 (94.66%) bites occurred over limbs, out of which 38 (50.66%) were in lower limbs. Most bites occur between 12 Noon to 12 Midnight 60 patients (81.2%). Out of 75 patients, 60 (80%) were poisonous snakebites, 20 (20%) were non-poisonous snakebites. Among 60 (80%) poisonous bites, 32 (53.34%) had neurotoxic manifestations and 28 (46.66%) had hemotoxic manifestations.CONCLUSIONSSnakebite is common in rural setup, in agricultural labourers. Most common victims are males in the age group between 20-40 years. Poisonous bites were more common than non-poisonous snake bites in this study. In neurotoxic envenomation ptosis was the commonest and earliest symptom while in hemotoxic envenomation, most common symptoms were bleeding from bite site and hematuria. The commonest complications were acute renal failure and respiratory paralysis. Shock, infection and gangrene were also noted in some patients. Maximum mortality was observed in patients who were admitted after 24 hours. Early hospitalization and timely ASV administration were the corner stones in the treatment of snakebite.

Comparison between peak systolic velocity of the inferior thyroid artery and technetium-99m pertechnetate thyroid uptake in differentiating Graves' disease from thyroiditis

ABSTRACT Objectives The differentiation between the various etiologies of thyrotoxicosis, including those with hyperthyroidism (especially Graves' disease [GD], the most common cause of hyperthyroidism) and without hyperthyroidism (like thyroiditis), is an important step in planning specific therapy. Technetium-99m (99mTc) pertechnetate thyroid scanning is the gold standard in differentiating GD from thyroiditis. However, this technique has limited availability, is contraindicated in pregnancy and lactation, and is not helpful in cases with history of recent exposure to excess iodine. The aim of this study was to identify the diagnostic value of the peak systolic velocity of the inferior thyroid artery (PSV-ITA) assessed by color-flow Doppler ultrasound (CFDU) and compare the sensitivity and specificity of this method versus 99mTc pertechnetate thyroid uptake. Subjects and methods We prospectively analyzed 65 patients (46 with GD and 19 with thyroiditis). All patients were evaluated with clinical history and physical examination and underwent 99mTc pertechnetate scanning and measurement of TRAb levels and PSV-ITA values by CFDU. The diagnosis was based on findings from signs and symptoms, physical examination, and 99mTc pertechnetate uptake. Results Patients with GD had significantly higher mean PSV-ITA values than those with thyroiditis. At a mean PSV-ITA cutoff value of 30 cm/sec, PSV-ITA discriminated GD from thyroiditis with a sensitivity of 91% and specificity of 89%. Conclusion Measurement of PSV-ITA by CFDU is a good diagnostic approach to discriminate between GD and thyroiditis, with sensitivity and specificity values comparable to those of 99mTc pertechnetate thyroid uptake.

The prevalence of bipolar spectrum disorder in medical students of Pakistan

Background: Bipolar affective disorder is cyclic swinging of mood between mania or hypo-mania and depression. Bipolar disorder is the sixth leading cause of disability worldwide and has a lifetime prevalence of about 1 to 3% in the general population. Despite a growing body of knowledge on bipolar spectrum disorder (BSD), relatively little is known about the clinical characteristics of BSD in medical students. This study evaluates the prevalence and severity of BSD in medical students in relation to certain socio-demographic factors like age, sex and class of education.Methods: A questionnaire based study was done on 298 medical students of Nishtar Medical University, Multan and Shaikh Zayed Medical College, Rahim Yar Khan chosen on basis of random sampling to test the prevalence of bipolar spectrum disorders using Mood Disorder questionnaire (MDQ). Out of these students 161 were males and 137 were females. Students were interviewed to obtain information about age, sex and academic year of education.Results: According to mood disorder questionnaire scoring, of the total 298 students 80 (26.84%) screened positive for bipolar spectrum disorder (BSD). Among 80 students who screened positive for BSD 43 (53.75%) are males while 37 (46.25%) are females. Class-wise distribution of BSD is as follows: Out of 80 students screened positive 15 (18.75%) are from 2nd year, 22 (27.5%) from 3rd year and 43 (53.75) from 4th year. Age-wise distribution of BSD is as following: Students of age 19, 20, 21, 22 and 23 years suffering from BSD were 5 (6.25%), 17 (21.25%), 23(28.75),22 (27.5%) and 13 (16.25%) respectively.Conclusions: In our study, the estimated rate of prevalence for bipolar spectrum disorder among medical students of Pakistan is 26.84%. There was no significant difference in prevalence on the basis of gender. Prevalence was increasing with both age and class wise distribution.

SPSS computer-based Software was used for analyzing the data. Results revealed that 91.2% of the farmers indicated mobile phone ownership. It was further reported that 87.20 % of the farmers used private sectors advisory staff to obtain agriculture information. Market information was ranked as the highest accessed information among the rest of farm-related use. Easy access to updated information and connectivity with stakeholders were reported as the highest perceived benefits of mobile phone use (4.63 & 4.72 mean). Findings reported that farmers' limited aptitude of Mobile phone usage and lack of awareness of information sources as major constraints in farm-related use of the Mobile phone. On the basis of findings, the current study provided recommendations and policy implications for utilizing the true potential of these ICT-enabled solutions in agriculture.

RESUMO: A agricultura é considerada como a principal força motriz na economia do Paquistão, empregando 45% da força de trabalho do país e gerando 20% do PIB nacional. O setor agrícola dos paquistaneses enfrenta inúmeros desafios, incluindo a não-adaptação da tecnologia agrícola entre os agricultores, devido a falta de acesso dos agricultores às informações agrícolas mais recentes. Neste contexto, o estudo atual enfoca o papel do telefone celular na disseminação de informações agrícolas entre os agricultores do distrito Muzaffargarhof Punjab, Paquistão. Uma técnica de amostragem em múltiplos estágios foi usada para coletar dados dos dois tehsils (cidades / sub-distritos) de Muzaffargarh, formulando uma amostra total de 180 agricultores. O software baseado em computador SPSS foi usado para analisar os dados. Os resultados mostraram que 91,2% dos agricultores tinham propriedade de telefones celulares. Verificou-se ainda que 87,20% dos agricultores contatam o pessoal consultivo do setor privado para obter informações sobre a agricultura. As informações de mercado foram classificadas como as mais acessadas entre os demais usos relacionados à fazenda (média de 41,45). O acesso fácil a informações atualizadas e a conectividade com as partes interessadas são relatados como os maiores benefícios percebidos do uso de telefones celulares entre os agricultores com valores médios de 4,63. e 4,72, respectivamente. Os resultados relataram que a capacidade limitada dos agricultores de usar o telefone celular e a falta de conhecimento das fontes de informação como principais restrições ao uso do telefone celular relacionado à fazenda. Com base nos resultados, recomenda-se a realização de sessões de treinamento com as comunidades agrícolas para criar conscientização e educá-las sobre o uso do telefone celular.

Results: This study revealed that the nephritis group had increased levels of uNGAL along with increased serum creatinine, increased urinary albumin creatinine ratio and decreased creatinine clearance [CG Formula] ascompared to systemic lupus erythematosus patients without having lupus nephritis [p Value <0.05]

Conclusion: These findings clearly indicate that uNGAL levels correlate strongly with the renal components of the disease activity. Thus, it can be stated that uNGAL can prove to be a noninvasive, reliable and sensitive biomarker to diagnose cases of lupus nephritis

Radionuclide Esophageal Transit Scintigraphy in Primary Hypothyroidism

BACKGROUND/AIMS: Esophageal dysmotility is associated with gastrointestinal dysmotility in various systemic and neuroregulatory disorders. Hypothyroidism has been reported to be associated with impaired motor function in esophagus due to accumulation of glycosaminoglycan hyaluronic acid in its soft tissues, leading to changes in various contraction and relaxation parameters of esophagus, particularly in the lower esophageal sphincter. In this study we evaluated esophageal transit times in patients of primary hypothyroidism using the technique of radionuclide esophageal transit scintigraphy. METHODS: Thirty-one patients of primary hypothyroidism and 15 euthyroid healthy controls were evaluated for esophageal transit time using 15–20 MBq of Technetium-99m sulfur colloid diluted in 10–15 mL of drinking water. Time activity curve was generated for each study and esophageal transit time was calculated as time taken for clearance of 90% radioactive bolus from the region of interest encompassing the esophagus. Esophageal transit time of more than 10 seconds was considered as prolonged. RESULTS: Patients of primary hypothyroidism had a significantly increased mean esophageal transit time of 19.35 ± 20.02 seconds in comparison to the mean time of 8.25 ± 1.71 seconds in healthy controls (P < 0.05). Esophageal transit time improved and in some patients even normalized after treatment with thyroxine. A positive correlation (r = 0.39, P < 0.05) albeit weak existed between the serum thyroid stimulating hormone and the observed esophageal transit time. CONCLUSIONS: A significant number of patients with primary hypothyroidism may have subclinical esophageal dysmotility with prolonged esophageal transit time which can be reversible by thyroxine treatment. Prolonged esophageal transit time in primary hypothyroidism may correlate with serum thyroid stimulating hormone levels.

Mother's perceptions of child mental health problems and services: a cross sectional study from Lahore

Objective: To assess the perceptions of mothers regarding child mental health problems, its causes, preferred treatment options, and to determine whom they would consult, if their child had a psychiatric illness

Methods: Following informed consent, a questionnaire covering perceptions regarding various aspects of child mental illness was used for data collection from mothers. They were asked to identify the symptoms and behaviours they considered psychopathological in children, which treatments they would prefer, where they would turn for help with a mentally ill child, and their understanding of the causes of child psychiatric disorders in addition to ways to increase awareness of child psychiatric issues in the society

Results: Ninety one mothers participated in the study. They equally perceived emotional, behavioural and cognitive symptoms as suggestive of mental ill health in childhood. Mothers perceived multiple causes of child mental health problems, including family problems, economic difficulties, social adversity and possession by evil spirits. A substantial proportion preferred medication, recitation of Holy Quran and psychotherapy as the preferred treatment options. Overall, mothers preferred consulting health professionals than religious scholars and faith healers. They were keen for steps to increase mental health awareness within their society

Conclusion: Despite different cultural perspective, mothers exhibit good understanding of symptoms of child mental health issues and appear open to various services and treatment options. Understanding parental perceptions and expectations from child psychiatric services are crucial in increasing families' engagement in treatment

Outcome of end-stage renal disease patients with advanced uremia and acidemia

Objective: To determine the outcome of End-Stage Renal Disease [ESRD] patients presenting with advanced uremia and acidemia requiring hemodialysis and adverse events seen within 72 hours of admission

Study Design: Cross-sectional study

Place and Duration of Study: Sindh Institute of Urology and Transplantation, Karachi, Pakistan, from October 2010 to March 2011

Methodology: ESRD patients with advanced uremia and acidemia were included in the study. History, physical examination, complete blood count, serum urea, creatinine, electrolytes, arterial blood gases analysis, and ultrasound of kidneys were done in each patient. Adverse events and outcome were recorded for the next 72 hours. Data was analyzed by SPSS version [10]. Mean value and standard deviation of quantitative measurements were calculated and statistical significance computed by t-test. A p-value

Results: Out of the 194 ESRD patients [mean age 46.54 +/- 14.07 years], 28 [14%] expired and 166 [86%] survived within 72 hours of admission. Hypotension requiring inotropic support was the commonest adverse event observed in 40 [20.6%] cases followed by fits in 31 [16%]; and 25 [12.9%] patients required ventilatory support. Mortality was high in patients above 50 years of age. There was no statistically significant difference between two genders regarding adverse events and mortality

Conclusion: The morbidity and mortality of patients with ESRD are serious concerns. Early referral of patients with ESRD, before they develop severe acidosis, can prevent significant morbidity and mortality

Mortality prediction in patients admitted in surgical intensive care unit by using APACHE IV

Objective: To predict the mortality by the mean Acute Physiology and Chronic Health Evaluation [APACHE] IV score of all the patients admitted in a Surgical Intensive Care Unit [ICU] and comparing the score of the survivors and non-survivors

Study Design: Descriptive study

Place and Duration of Study: Surgical Intensive Care Unit, Mayo Hospital, Lahore, from June 2013 to November 2014

Methodology: All adult patients admitted in the Surgical ICU were included in this study. The demographics and other data of the patients were recorded. The APACHE IV scores of all patients were calculated at the time of admission. The scores of the survivors and the non-survivors were compared for prediction of survival and mortality

Results: The age of these patients ranged from 13 to 70 [mean 38.39] years with 86 [55.48%] males and 69 [44.52%] females. The mean APACHE IV score of these patients was 34.96 +/- 14.93 ranging from 11 to 63 years. Eighty-three [53.55%] patients survived and 72 [46.45%] died. With respect to gender, 41 [47.67%] males out of 86 and 31 [44.92%] females out of 69 did not survive. The mortality increased with an increase in APACHE IV score and all the patients with score more than 39 did not survive

Conclusion: The predicted mortality can be assessed by APACHE IV score, so it is good for application among the surgical ICU patients

Comparison of short term outcome between vaginal and abdominal hysterectomy

Objectives: To compare short term outcomes between vaginal and abdominal hysterectomy

Subject and Method: It was a cross sectional study and conducted in the department of obstetrics and gynecology unit - III, Jinnah hospital Lahore. Study was carried out over a period of one year from Jul 2013 to Jun 2014. Non probability purposive technique was used for sampling. A total of 134 patients were included in the study after fulfilling the inclusion criteria. The cases studied included 84 patients undergoing total abdominal hysterectomy and 50 cases of vaginal hysterectomy. The outcome measures were operative time, need for blood transfusion, postoperative febrile morbidity, wound infection, secondary hemorrhage and duration of hospital stay

Results: Mean age of the patient was 51.2+ 5.3 years and 55.3+ 6.1 years in abdominal hysterectomy group and vaginal hysterectomy group respectively. Fever was commoner in abdominal hysterectomy group i.e; 5.9 % compared to 2% in vaginal hysterectomy group. Mean duration of hospital stay after abdominal hysterectomy was 3.0+ 0.6 days and after vaginal hysterectomy, it was 2.1+ 0.4 days. Mean operating time in abdominal hysterectomy group was 90 + 10.1 minutes compared to vaginal hysterectomy group which was 70 + 8.5 minutes. Need for blood transfusion was lesser in vaginal hysterectomy group compared to abdominal hysterectomy group [8.33% VS 2%]

Conclusion: Short term morbidity is lesser after vaginal hysterectomy compared to the abdominal hysterectomy

Correlation between acute ischemic stroke, higher total cholesterol level and high barthel index score

Objectives: To determine the correlation between higher total cholesterol level and high Barthel Index score in patients with acute ischemic stroke

Methodology: This cross sectional study was conducted at Radiology department and Medical Unit 1, Allied Hospital, Faisalabad for duration of 6 months from January 2015 to June 2015. 200 patients were included through Consecutive [non-probability] sampling technique. All the patients were undergone CT scan Brain from the radiology department of the Allied hospital to determine the respective changes [hypo dense area] of the ischemic stroke. Fasting serum cholesterol was measured in all patients after an overnight fast of 12 hours by drawing blood through 5cc BD syringe by me. Then all the patients were assessed by using Barthel Index score [BI]. Higher total cholesterol and high BI score were labeled after assessing the laboratory and clinical findings. The data was analyzed by using SPSS version 17.0. Spearman Rank correlation coefficient was calculated to BI score in patients with ischemic stroke. P-value<0.05 was considered as significant

Results: The mean age of the patients was noted as 61.76 +/- 11.55 years. In this study 55.50% were males and 44.50% patients were females. The mean total cholesterol value of patients was noted as 251.59 +/- 71.15 mg/dl. Out of 200 patients, 112 [56%] patients had high cholesterol [>200mg/dl] whereas 88 [44%] patient had low cholesterol of [<200mg/dl]. In this study the results showed that the mean value of total Barthel index score was 57.50 +/- 19.52. The study results described that 103 [51.50%] patients had high Barthel index score [>53] whereas 97 [48.50%] patients had low Barthel index score [<53]. Spearman correlation coefficient was calculated between high TC and high BI score as r= 0.631. This value was statistically significant i.e. p-value=0.000

Conclusion: With the help of this study, we found a significant positive relationship between high TC and high BI score in patients presented with ischemic stroke. Now we can better prognosticate the functional outcome of ischemic stroke in our patients
