Rationale: Clinical trial design in interstitial lung diseases (ILDs) has been hampered by lack of consensus on appropriate outcome measures for reliably assessing treatment response. In the setting of connective tissue diseases (CTDs), some measures of ILD disease activity and severity may be confounded by non-pulmonary comorbidities. Methods: The Connective Tissue Disease associated Interstitial Lung Disease (CTD-ILD) working group of Outcome Measures in Rheumatology-a non-profit international organisation dedicated to consensus methodology in identification of outcome measures-conducted a series of investigations which included a Delphi process including >248 ILD medical experts as well as patient focus groups culminating in a nominal group panel of ILD experts and patients. The goal was to define and develop a consensus on the status of outcome measure candidates for use in randomised controlled trials in CTD-ILD and idiopathic pulmonary fibrosis (IPF). Results: A core set comprising specific measures in the domains of lung physiology, lung imaging, survival, dyspnoea, cough and health-related quality of life is proposed as appropriate for consideration for use in a hypothetical 1-year multicentre clinical trial for either CTD-ILD or IPF. As many widely used instruments were found to lack full validation, an agenda for future research is proposed. Conclusion: Identification of consensus preliminary domains and instruments to measure them was attained and is a major advance anticipated to facilitate multicentre RCTs in the field.

- Abstract
Background: Patients with chronic kidney disease (CKD) undergoing maintenance haemodialysis (MHD) develop several abnormalities of left ventricular (LV) structure and function. Speckle-tracking echocardiography permits compressive assessment of LV myocardial deformation. Previous studies involving CKD patients have shown a significant reduction in LV global longitudinal strain (GLS) with strong prognostic implications. However, the other components of LV deformation have not been fully elucidated., Methods: A total of 90 CKD patients undergoing MHD (mean age 41.3 ± 12.5 years, 80% men) were compared with 45 apparently healthy age- and gender-matched controls., Results: The CKD patients had a high prevalence (77.8% patients) of LV hypertrophy. They also had a significantly elevated ratio of early diastolic mitral inflow velocity to annular velocity (12.1 ± 4.6 vs. 7.1 ± 1.5, p < .001) indicating a high prevalence of LV diastolic dysfunction. LV ejection fraction (LVEF) was the same between the two groups, but the CKD patients had significantly impaired LVGLS (-17.8 ± 3.9 vs. -20.8 ± 2.6, p < .001), global circumferential strain (-14.0 ± 3.5 vs. -16.1 ± 3.4, p = .001), LV apical rotation (6.6 ± 4.7° vs. 8.8 ± 4.0°, p = .008) and LV twist (12.8 ± 6.1° vs. 15.0 ± 6.0°, p = .037). There was no difference in the global radial strain between the two groups., Conclusions: The present study shows that CKD patients on MHD have significantly impaired LV longitudinal and circumferential mechanics despite preserved LVEF. The prognostic implications of reduced LVGLS have already been demonstrated previously. Future studies are needed to assess the prognostic implications of abnormal LV circumferential mechanics as well as their reversibility following renal transplant.

- Abstract
Purpose of Review: Overlapping hemodynamics in constrictive pericarditis (CP) and restrictive cardiomyopathy (RCM) often pose difficulties in establishing accurate diagnosis. Echocardiography is the first-line imaging modality used for this purpose, but no single echocardiographic parameter is sufficiently robust for distinguishing between the two conditions. The newer developments may improve the diagnostic accuracy of echocardiography in this setting., Recent Findings: Recent studies have validated multiparametric algorithms, based on conventional echocardiographic parameters, which enable high sensitivity and specificity for distinguishing between CP and RCM. In addition, myocardial deformation analysis using speckle-tracking echocardiography has revealed distinct pattern of abnormalities in the two conditions. CP is characterized by impaired left ventricular apical rotation with relatively preserved longitudinal strain, esp. of ventricular and atrial septum. In contrast, RCM results in global and marked impairment of left ventricular longitudinal strain with initially preserved circumferential mechanics. Combining multiple echocardiographic parameters into step-wise algorithms and incorporation of myocardial deformation analysis help improve the diagnostic accuracy of echocardiography for distinguishing between CP and RCM. The use of machine-learning may allow easy integration of a wide range of echocardiographic and clinical parameters to permit accurate, automated diagnosis, with less dependence on the user expertise., (© 2022.

- Abstract
Ethnic-specific normal reference ranges for various echocardiographic measurements are essential for accurate diagnostic interpretation and clinical decision-making. Unfortunately, such normative data for Indians is lacking. A total of 880 healthy volunteers (mean age 39.7 ± 12.3 years, 63.8% men) from six centers across different regions of India were enrolled in this study. Comprehensive transthoracic echocardiographic study was performed in all subjects, in accordance with the existing guideline recommendations. Cardiac chamber dimensions [Left ventricular (LV) end-diastolic diameter and volume; right ventricular (RV) basal diameter, left atrial volume] were obtained and indexed to body surface area. LV ejection fraction, LV global longitudinal strain (LVGLS) and measures of RV systolic function were also obtained. The subjects were divided into 3 age groups (35 years or less, 36-55 years and 56 years or above) for analysis. Age- and gender-specific reference values for various clinically relevant echocardiographic parameters were derived. Compared with women, men had larger cardiac chamber dimensions and volumes, but not when indexed. In contrast, the women had higher LV systolic function, but right ventricular systolic function was not different. The indexed LV volumes in our study were much smaller than those recommended in the American Society of Echocardiography (ASE)/European Association of Cardiovascular Imaging (EACVI) 2015 chamber quantification guidelines but were similar to those reported in the Indian patients included in the recent World Alliance Societies of Echocardiography (WASE) Normal Values Study. LVGLS was also comparable with the WASE data. INDEA study is the first, multi-centric study to provide normal echocardiographic references values for Indian adults. Our findings underscore the need to follow India-specific reference values, instead of those recommended by the ASE/EACVI, which are largely applicable to the western populations.

- Abstract
Radiotherapy is an important treatment modality for various thoracic malignancies but is associated with long-term risk of radiation-associated valve disease (RAVD). We hereby report a case of a lady who had received radiotherapy 30 years back for carcinoma breast and was now found to be having clinically significant RAVD involving all the four cardiac valves. Simultaneous involvement of all the four valves in RAVD is extremely rare and has not been reported previously., Competing Interests: There are no conflicts of interest., (Copyright: © 2021 Heart Views.)

- Abstract
Spindle cell lipoma (SCL) is an uncommon histological variant of lipoma that accounts for 1.5% of all adipose tumors. It rarely occurs in the oral cavity. The most common sites of involvement are the buccal mucosa, tongue, lip, alveolar mucosa, gingiva, and palate. Submandibular space is a very rare site of occurrence for SCL. When occurs in this site, SCL mainly involves the 4th-7th decade with a female predominance. Due to wide communications of submandibular space, the actual extent and appearance of the lesions present here gets masked up especially those involving the deeper tissues leading to an inaccurate diagnosis. Wide overlap of clinical and histopathological features of SCL to other clinical pathologies leads to a challenging task for the clinicians to reach an accurate diagnosis. To our knowledge, only four cases of intraoral SCL involving the submandibular region directly or indirectly have been reported in the literature. Here we represent another rare case of SCL in an 18-year-old male patient along with a concise review of the literature. This case appears to be quite rare due to its location (submandibular space), age, and sex of the patient (18/M).

- Abstract
Left ventricular (LV) thrombi usually occur in the setting of global or regional LV systolic dysfunction and are extremely rare in the absence of LV wall motion abnormalities. We report here a case of a 23-year-old female who presented with cardioembolic stroke due to ulcerative colitis. To determine the cause of stroke, several investigations and evaluations were carried out, but the results were mostly normal or unremarkable. Transthoracic echocardiography revealed an oscillating pedunculated globular mass, which was eventually resected due to recurrent transient ischemic attacks. The histopathology of the excised mass revealed it to be an organized thrombus with acute and chronic inflammatory cells and fibroblasts. The uncommon etiology combined with the unusual appearance of the thrombus presented a major diagnostic and therapeutic dilemma for this exceedingly rare cause for intracardiac thrombus formation. Therefore, it would be useful to have a low threshold for screening patients with active inflammatory bowel disease for possible ventricular thrombosis before discharge, especially if other risk factors are present., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Saudi Journal of Medicine & Medical Sciences.)

- Abstract
Background: Low-flow, low-gradient severe aortic stenosis (LFLGAS) is a common clinical entity and is associated with poor prognosis. Increased left ventricular (LV) afterload is one of the mechanisms contributing to low LV stroke volume index (SVi) in these patients. Aortic stiffness is an important determinant of LV afterload, but no previous study has evaluated its relationship with LVSVi in patients with AS., Methods: Fifty-seven patients (mean age 66 ± 8 years, 71.9% men) with severe AS [aortic valve area (AVA) < 1.0 cm
2 ] undergoing aortic valve replacement (AVR) were included in this study. Echocardiographic parameters of AS were correlated with carotid-femoral pulse wave velocity (cfPWV), a measure of aortic stiffness, derived using PeriScope® device., Results: Mean AVA was 0.63 ± 0.17 cm2 with mean and peak transvalvular gradient 56.5 ± 18.8 mmHg and 83.2 ± 25.2 mmHg, respectively. Nearly half (26 of 57, 45.6%) of the subjects had SVi <35 mL/m2 , indicative of low-flow severe AS. These subjects had lower AVA, lower aortic valve gradient, and LV ejection fraction. CfPWV was numerically lower in these subjects [median 1467 (interquartile range 978, 2259) vs 1588 (1106, 2167)] but the difference was not statistically significant (p = 0.66). However, when analyzed as a continuous variable, cfPWV had significant positive correlation with SVi (Pearson's r 0.268, p = 0.048) and mean aortic valve gradient (Pearson's r 0.274, p = 0.043)., Conclusions: In patients with severe AS undergoing AVR, aortic stiffness measured using cfPWV is not a determinant of low-flow state. Instead, an increasing cfPWV tends to be associated with increasing transvalvular flow and gradient in these patients., Competing Interests: Declaration of competing interest All authors have none to declare., (Copyright © 2020 Cardiological Society of India.

- Abstract
A 25-year-old female, with systemic lupus erythematosus and antiphospholipid antibody syndrome, presented with exertional dyspnoea. Echocardiography showed a large (2.0 cm × 1.1 cm), echogenic, heterogeneous mass in the left ventricular outflow tract, under the aortic valve, attached to the ventricular aspect of the anterior mitral leaflet. Tiny flagellar, frond-like structures were seen attached to the surface of the mass. There was mitral regurgitation. These echocardiographic features were suggestive of a papillary fibroelastoma, but the histopathology of the excised mass revealed it to be a thrombus, which was consistent with a diagnosis of non-bacterial thrombotic endocarditis (NBTE). This case represents a rare histopathologically confirmed NBTE presenting as an unusually large mass in the left ventricular outflow tract., Competing Interests: None

- Abstract
Background: Prolonged aerobic exercise such as marathon running produces supraphysiological hemodynamic stress that can potentially affect the athlete's cardiac homeostasis. While cardiac structural and functional adaptations in professional athletes are well characterized, only a limited information is available for recreational runners undergoing this supraphysiological stress., Methods: Premarathon and post-marathon echocardiography was performed in 50 recreational marathon runners [age 40.8 ± 7.5 years, 44 (88%) males; running distance 42.195 km]. All the runners received 4-month training for the marathon. The baseline echocardiogram and N-terminal B-type natriuretic peptide (NT-proBNP) were obtained before training, whereas the post-marathon study was performed within 10 days (7.27 ± 0.92 days) of completion of marathon. Two-dimensional speckle-tracking echocardiography was used for characterizing the changes in myocardial mechanics., Results: There was a significant reduction in heart rate post-marathon, whereas the levels of NT-proBNP increased significantly (86.0 ± 9.5 pg/ml vs 106.5 ± 24.2 pg/ml, p = 0.001). The left ventricular (LV) end-diastolic volume (61.8 ± 16.5 ml vs 72.8 ± 5.1 ml, p < 0.001), LV mass (120.2 ± 30.0 gm vs 160.3 ± 43.0 gm, p < 0.001), and LV ejection fraction (64.9 ± 5.6% vs 72.0 ± 5.7%, p < 0.001) also increased significantly. However, there was a significant attenuation in LV global longitudinal (-19.3 ± 2.71% vs -16.5 ± 4.6%, p = 0.003) and circumferential strain (-17.2 ± 2.41% vs -15.2 ± 2.6%, p = 0.001) post-marathon. The LV global radial strain showed a nonsignificant reduction., Conclusion: Recreational marathon runners have reduced longitudinal and circumferential shortening of the left ventricle with elevation of NT-proBNP. However, the LV ejection performance remains maintained because of an increase in the LV end-diastolic volume and mass. These changes suggest the possibility of "myocardial fatigue" occurring in response to supraphysiological hemodynamic stress of marathon running., (Copyright © 2018. Published by Elsevier B.V.)

- Abstract
Introduction and Aims: While persons with addiction are often hospitalised, hospitals typically employ abstinence-based policies specific to illicit drug use. Although illicit drug use is known to occur within hospitals, this problem has not been well characterised. Therefore, we sought to investigate the prevalence of and factors associated with having ever used drugs in hospital among people who use drugs in Vancouver, Canada., Design and Methods: Data were derived from prospective cohort studies of people who use drugs between December 2012 and May 2013. Multivariable logistic regression was used to identify demographic and behavioural factors associated with having ever used illicit drugs in hospital., Results: Among 1028 participants who had experienced ≥1 hospitalisation, 43.9% reported having ever used drugs while hospitalised. In multivariable analyses, factors positively associated with having ever used drugs in hospital included daily cocaine injection and daily crack non-injection (both P < 0.05). Factors negatively associated with the outcome included older age and male gender (both P < 0.05). The most common reasons for drug use in hospital were 'wanting to use' and 'being in withdrawal'. Drugs were most commonly used in patient washrooms., Discussion and Conclusions: Our findings demonstrate that an abstinence-based approach to drug use in hospitals may be ineffective at prohibiting drug consumption. High-risk drug use behaviours arising from ongoing drug use may pose risks for further harm and illness. Efforts to minimise the harms associated with using drugs in hospital are urgently needed.

- Abstract
Introduction: Sarcoidosis is a multi-organ system granulomatous disease of unknown origin with an incidence of 1-40/100,000. Though pulmonary manifestations are predominant, ocular sarcoidosis (OS) affects 25-50% of patients with sarcoidosis and can lead to blindness., Methods: A retrospective, single-center chart review of sarcoidosis cases investigated variables associated with the development of OS. Inclusion criteria were biopsy-proven sarcoidosis, disease duration greater than 1 year, documented smoking status on chart review and documentation of sarcoid-related eye disease. Multivariate analysis identified independent risk factors for OS., Results: Of 269 charts reviewed, 109 patients met inclusion criteria. The OS group had a significantly higher proportion of smokers (71.4%) than without OS (42.0%, p=0.027) with no difference (p=0.61) in median number of pack years. Male sex was significantly higher in the OS group (57.1% versus 26.1%, p=0.009). Median duration of sarcoidosis was higher in the OS group (10 versus 4 years, p=0.031). Multivariate regression identified tobacco exposure (OR=5.25, p=0.007, 95% CI 1.58-17.41), male sex (OR=7.48, p=0.002, 95% CI 2.15-26.01), and age (OR=1.114, p=0.002, 95% CI 1.04-1.19) as concomitant risk factors for the development of OS., Conclusion: To date, there are few dedicated investigations of risk factors for OS, especially smoking. This investigation identified male sex, age, and tobacco exposure as independent risk factors for OS. Though disease duration did not withstand regression analysis in this moderately sized group, age at chart review suggests screening for OS should not remit but rather intensify in aging patients with sarcoidosis.

- Abstract
Objective: The impact and natural history of connective tissue disease related interstitial lung disease (CTD-ILD) are poorly understood; and have not been previously described from the patient's perspective. This investigation sought insight into CTD-ILD from the patients' perspective to add to our knowledge of CTD-ILD, identify disease-specific areas of unmet need and gather potentially meaningful information towards development of disease-specific patient-reported outcome measures (PROMs)., Methods: A mixed methods design incorporating patient focus groups (FGs) querying disease progression and life impact followed by questionnaires with items of importance generated by >250 ILD specialists were implemented among CTD-ILD patients with rheumatoid arthritis, idiopathic inflammatory myopathies, systemic sclerosis, and other CTD subtypes. FG data were analyzed through inductive analysis with five independent analysts, including a patient research partner. Questionnaires were analyzed through Fisher's Exact tests and hierarchal cluster analysis., Results: Six multicenter FGs included 45 patients. Biophysiologic themes were cough and dyspnea, both pervasively impacting health related quality of life (HRQoL). Language indicating dyspnea was unexpected, unique and contextual. Psycho-social themes were Living with Uncertainty, Struggle over Self-Identity, and Self-Efficacy - with education and clinician communication strongly emphasised. All questionnaire items were rated 'moderately' to 'extremely' important with 10 items of highest importance identified by cluster analysis., Conclusion: Patients with CTD-ILD informed our understanding of symptoms and impact on HRQoL. Cough and dyspnea are central to the CTD-ILD experience.

- Abstract
Background: Autocrine motility factor receptor (AMFR) is a tumour motility stimulating protein secreted by tumour cells. The protein encoded by this gene is a glycosylated transmembrane protein and a receptor for autocrine motility factor. It has been known to play a role in progression of neoplastic lesions. Basement membranes are specialized extracellular matrices that serve as structural barriers as well as substrates for cellular interactions. The network of type IV collagen is thought to define the scaffold integrating other components such as laminins and perlecan into highly organized supramolecular architecture. The aim of this study was to determine and evaluate the immunohistochemical expression of Type IV Collagen and Autocrine motility factor receptor in odontogenic lesions., Materials and Methods: Immunohistochemical expression of Type IV Collagen and Autocrine motility factor receptor was evaluated in 31 odontogenic lesions, including unicystic ameloblastoma, multicystic ameloblastoma, keratocystic odontogenic tumour and ameloblastic carcinoma. Normal follicular tissue formed the control., Results: Maximum expression for Type IV Collagen was seen in multicystic ameloblastoma and minimum expression in keratocystic odontogenic tumour. The maximum expression of AMFR was seen in ameloblastic carcinoma and minimum expression in multicystic ameloblastoma., Conclusion: The results of this study suggested an association of loss of expression of type IV Collagen with progression of lesion. AMFR expression was found to be associated with the aggressive potential of tumours.

- Abstract
Introduction: Gouty arthritis and hyperuricemia have ailed humans for centuries. Recent advances in understanding of the mechanism(s) of their development have changed our perception of the disease process. Despite these gains, the treatment options available are limited. The FDA approval of febuxostat for the treatment of hyperuricemia in gout has been a significant step forward. Since its approval in 2009, febuxostat has proven to be safe and efficacious although concerns remain regarding its long-term effects and superiority to other uricosuric agents, such as allopurinol., Areas Covered: A comprehensive literature review of PubMed and Ovid examining clinical trials and post-marketing studies yielded congruent findings on efficacy and safety in elderly populations and those with mild-to-moderate renal/hepatic impairment. A lack of literature and clinical studies was found with regard to comparison of febuxostat to FDA-approved high-dose allopurinol (> 300 mg), the safety of febuxostat in the treatment of severe renal/hepatic impairment and the benefit in the treatment of secondary cases of hyperuricemia., Expert Opinion: Febuxostat is effective in the treatment of mild-to-moderate renal/hepatic impairment with dramatic effects on the serum urate level. It can be used safely in patients with hypersensitivity reactions to allopurinol. Further research is needed to determine the long-term benefits and risks.

- Abstract
Tender swellings of the mandible are majorly due to inflammatory lesions like infected dental cyst, peri-apical abscess or neoplasms like osteoblastomas, cementoblastomas, osteosarcoma and intraosseous squamous cell carcinoma. Florid cemento-osseous dysplasia is a subgroup of cemento-osseous dysplasia typically found in middle-aged black women as multiple, non-tender, diffuse, lobulated radio-opacities distributed throughout the maxilla and mandible, which are usually bilaterally symmetrical. Histologically, they are composed of proliferating fibrous connective tissue stroma containing foci of cementum, osteoid and bone. Florid cemento-osseous dysplasia is rare in Indian population and among all cases of florid cemento-osseous dysplasia, almost 97% of the cases reported till date are in females. The present case describes florid cemento-osseous dysplasia in a 26-year-old male who reported with pain in the left mandibular premolar region.

- Abstract
Background: Oral habits such as alcohol consumption and tobacco chewing are considered to be initiators of dysplastic changes in the oral mucosa., Aim: The aim of this study was to determine and compare the alteration in apparently normal buccal mucosal cells due to effect of alcohol and tobacco by assessing silver-stained nucleolar organiser regions (AgNORs) and micronuclei., Materials and Methods: The study comprised a total of 100 subjects which were divided into four groups with 25 subjects having alcohol consuming habit, 25 subjects were tobacco consumer, 25 were both alcohol and tobacco consumer and 25 formed control group who neither consumed alcohol nor tobacco. Two cytological smears were taken from each subject with the help of cytological brush. The smear was then wet fixed and stained with AgNOR and acridine orange staining technique and assessed for nucleolar organiser region and micronuclei count respectively. 500 cells per slide were counted to note the changes., Results: Mann-Whitney test was applied to assess the variation in the number of AgNORs and micronuclei count between different groups. Cytological changes in each group revealed the increase in mean AgNORs and micronuclei count in subjects with combined alcohol and tobacco consumption when compared with individual groups., Conclusions: Tobacco and alcohol consumption produce alteration in apparently normal buccal mucosal cells, which may cumulatively lead to carcinomatous changes. Result of these changes may be used as educational tool in cessation of habits.

22. Neoplastic meningitis resulting from hematological malignancies: pharmacokinetic considerations and maximizing outcome.

- Abstract
Neoplastic meningitis, also known as leptomeningeal metastases, is a complication of various types of cancer that occurs when tumor cells enter the cerebrospinal fluid (CSF), travel along CSF pathways and grow. Treatment options include drug delivery directly into the CNS or systemic administration for targeted action in the CNS. CNS drug delivery is limited by the blood-brain barrier and the blood-CSF barrier. It may be possible to partially overcome this by using high-dose systemic therapy; however, this is done at the possible expense of increased systemic toxicity. Intra-CSF drug delivery bypasses the blood-brain barrier and allows direct access of the chemotherapeutic agent to the CSF. Because neoplastic meningitis occurs in an increasingly large percentage of all cancer patients, it is imperative to optimize drug delivery to the CSF and meninges. Both the pharmacokinetic profile of the chemotherapeutic agent and the site of administration influence therapeutic efficacy. Achieving prolonged therapeutic cytotoxic drug concentrations and even distribution in the CSF will improve efficacy. In this article we summarize data on the efficacy, safety and outcome of high-dose systemic and intra-CSF treatments.

- Abstract
Seizure and epilepsy are common neurologic issues in cancer patients. Etiologies include structural abnormalities of the brain (eg, brain metastasis), cerebrovascular disease, reversible posterior leukoencephalopathy syndrome (RPLS), and radiation toxicity. Seizures associated with these etiologies often have focal features. Metabolic causes include hypoglycemia, electrolyte abnormalities, tumor lysis syndrome, thrombotic thrombocytopenic purpura (TTP), and medications used in cancer. A careful clinical evaluation can suggest the seizure etiology and guide subsequent work-up. Nonconvulsive status epilepticus should be suspected with persistent decreased level of consciousness following a seizure. Certain etiologies, such as RPLS and TTP, must be treated aggressively to minimize permanent neurologic injury. Routine prophylaxis with antiepileptic drugs (AEDs) is not recommended in patients with primary brain tumors or brain metastasis who have never had a seizure. Where indicated, the selection of AEDs should take into consideration side effects and interactions with chemotherapy. For this reason, non-enzyme-inducing AEDs are preferable in the cancer setting.

- Abstract
We describe a patient who presented at our epilepsy-monitoring unit with myoclonic jerks, and was diagnosed with juvenile myoclonic epilepsy (JME). Imaging of his brain revealed partial agenesis of the corpus callosum (ACC). We discuss the known genetic basis of both JME and ACC, as well as the role of the corpus callosum (CC) in primary generalized epilepsy. Both JME and ACC are associated with gene loci on chromosome 15q14. Structural brain abnormalities other than ACC, such as atrophy of the corpus callosum have been reported in patients with JME. ACC has been associated with seizures, suggesting an anti-epileptogenic role of the corpus callosum. On the other hand, corpus callosotomy is used to treat refractory idiopathic generalized epilepsy, which shows that the corpus callosum may play an epileptogenic role. The occurrence of both these conditions in one patient raises the question of whether they are purely coincidental or if there is a common basis for both. Several issues need to be addressed: the mechanism of seizure generalization in the setting of partial ACC, the possible role of other structures in generalization, and whether the ACC contributes to epileptogenesis as a result of the lack of a normal CC inhibitory effect.

- Abstract
In India, the prevalence of iron deficiency is high due to both low iron intake and low availability from foods of plant origin. We investigated the effect of different wheat products on iron availability by testing haemoglobin regeneration efficiency using a rat model. Wheat grains processed into whole wheat flour, pearled wheat flour and broken wheat were used to prepare chapati, parantha and porridge. All samples were analysed for proximate principles, minerals, namely calcium, iron, zinc, sodium, potassium, fibre, phytin phosphorus and total phenols. Protein, fat, fibre, phytate and total phenols of pearled wheat flour were lower than whole wheat flour. All minerals except zinc were significantly higher (P < 0.001) in whole wheat flour while soluble iron was higher in pearled wheat flour. Cooking resulted in an increase in soluble iron and neutral detergent fibre (P < 0.001) and decrease in phytin phosphorus and total phenols. Haemoglobin regeneration efficiency (HRE) of pearled wheat flour was significantly higher than whole wheat flour. Cooking resulted in significant (P < 0.05) increase in HRE and HRE of chapati was higher than parantha. Soluble iron and HRE were significantly associated.
