    Abstract Esophageal variceal bleeding remains the leading cause of acute mortality in patients with cirrhosis. As per guidelines, upper gastrointestinal screening endoscopy is recommended for all patients with cirrhosis to rule out esophageal varices. However, only 50% of newly diagnosed patients with cirrhosis have Esophageal varices. Hence there is a need for non-invasive parameters to predict the presence of esophageal varices to restrict the endoscopic studies to those with a high probability of having varices. In this study, we aimed to identify the effectiveness of Platelet Count/Spleen Length Ratio as a non-invasive predictor of esophageal varices.
    Material: An observational cross-sectional study was conducted including 52 patients with liver cirrhosis without a previous history of upper GI bleeding. Relevant clinical parameters were assessed including complete hemogram, upper GI endoscopy, and ultrasonographic measurement of spleen length. Patients were divided into two groups, one with esophageal varices and the other without esophageal varices. Platelet Count/Spleen Length Ratio was compared between these two groups.
    Observation: Out of the study population 65.38% of the patients had Oesophageal varices. The following observations were made in oesophageal variceal group and non-variceal group respectively; Mean spleen length was 156.26 ± 13.64 mm and 126.06 ± 6.40 mm(p<0.001), mean platelet count was 102882 ± 20188/mm3 and 156000 ± 36378 mm3 (p<0.001), Platelet Count/Spleen Length Ratio was 672.82 ± 188.06 and 1243.55 ± 307.53 (p<0.001). Platelet Count/Spleen Length Ratio of <926 was found to have a sensitivity of 91% in predicting varices and the specificity was 78%.
    Conclusion: Platelet Count/Spleen Length RATIO can be used as a predictor of esophageal varices and also to identify the subset of patients who require endoscopy for the prophylactic management of variceal bleeding. Therefore, to reduce the burden on the endoscopy units, avoiding unnecessary screening endoscopies.

    Abstract Pneumonia is an infection in one or both the lungs because of virus or bacteria through breathing air. It inflames air sacs in lungs which fill with fluid which further leads to problems in respiration. Pneumonia is interpreted by radiologists by observing abnormality in lungs in case of fluid in Chest X-Rays. Computer Aided Detection Diagnosis (CAD) tools can assist radiologists by improving their diagnostic accuracy. Such CAD tools use neural networks which are trained on Chest X-Ray dataset to classify a Chest X-Ray into normal or infected with Pneumonia. Convolution neural networks have shown remarkable performance in object detection in an image. Quaternion Convolution neural network (QCNN) is a generalization of conventional convolution neural networks. QCNN treats all three channels (R, G, B) of color image as a single unit and it extracts better representative features and which further improves classification. In this paper, we have trained Quaternion residual network on a publicly available large Chest X-Ray dataset on Kaggle repository and obtained classification accuracy of 93.75% and F-score of .94. We have also compared our performance with other CNN architectures. We found that classification accuracy was higher with Quaternion Residual network when we compared it with a real valued Residual network.

    Abstract Our understanding of gastric motility disorder--diabetic gastroparesis has advanced in the last ten to fifteen years, but the published data regarding pathogenesis are confusing and show conflicting results. The pathogenesis is sometimes linked with hyperglycemia, autonomic neuropathy, gastrointestinal hormone or myogenic mechanism. Antral hypomotility is often associated with hyperglycemia which is often accompanied by reduction in duodenal waves. Varying level of motilin, a gastrokinetic hormone has been reported. However none of the mechanism could explain the exact pathogenesis. The relationship of this mortality disorder with clinical symptoms is not always established, however nausea and vomiting lasting for days or weeks are the prominent symptoms. Other symptoms are post-prandial fullness, early satiety, bloating, belching, and vague abdominal discomfort. In a few cases, it may be the cause of poor nutrition, uncontrolled diabetes and recurrent ketoacidosis. Last one or two decades have seen some advancement in the investigational procedures like scintigraphy, radio-opaque markers, breath test, electrogastrography and MRI. Which can lead to a proper diagnosis. Such objective assessment is all the more important as nearly half of the patients do not have any symptom. Symptomatic improvement of gastroparetic patients should be the aim and in asymptomatic patients, treatment is often not recommended. Some dietary advice and prokinetic agents like metoclopramide, cisapride etc. are often prescribed but much needs to be further known as management is not always uniformly rewarding.

    Abstract Introduction: Liver biopsy is considered as a gold standard for the diagnosis of cirrhosis. Till date there is no non-invasive marker to replace it.
    Aim: To investigate the effectiveness of Aspartate aminotransferase-to-platelet ratio index (APRI) as a non-invasive marker for liver cirrhosis.
    Materials and methods: Fifty-one patients with cirrhosis, identified on USG abdomen were included in study. Platelet count and Aspartate aminotransferase (AST) were done using haematology automatic analyser and automatic HITACHI-912 Auto Analyser respectively. APRI was calculated for every patient using the formula {(AST / ULN) x 100}/platelet count (10(9)/L). Predictive accuracy was evaluated with a receiver-operating characteristics (ROC) curve.
    Results: APRI correctly classified 49 (96.1%) patients of cirrhosis with area under the ROC curve of 0.973 (95% CI) at cut-off 0.65 with negative predictive value (NPV) and Positive predictive value (PPV) of 96% and 96.1% respectively. The sensitivity and specificity of the test was found to be 96% and 96.1% respectively.
    Conclusion: APRI could identify cirrhosis with high degree of accuracy in the studied patients.

    Abstract Background & objectives: Early neurological deterioration (END) occurs in about 20 to 40 per cent of patients with acute ischaemic stroke and results in increased mortality and functional disability. In recent studies relative dehydration has been found to be associated with END in patients with acute ischaemic stroke. This study was conducted to identify factors useful for predicting END and to assess the role of blood urea nitrogen/creatinine ratio (BUN/creatinine) and urine specific gravity (USG) as predictors of END in patients with acute ischaemic stroke.
    Methods: The present study was an observational prospective study. Various parameters comprising demographic, clinical, laboratory and radiological variables along with stroke severity were assessed and studied as predictors of early neurological deterioration in 114 consecutive patients presenting to the Emergency department during 2012. BUN/creatinine >15 and USG >1.010 were studied as markers of relative dehydration contributing to END.
    Results: Of the 114 patients enrolled in the study, END was observed in 25 (21.9%) patients. National Institutes Health Stroke Scale score (NIHSS) ≥ 12 at admission was found to be an independent risk factor for END. Amongst markers of relative dehydration, BUN/creatinine >15 at admission was found to be an independent risk factor for END, as also USG >1.010. Also, cerebral oedema and size of hypodensity >1/3 rd of the middle cerebral artery territory on cranial CT were observed to be independent risk factors for END.
    Interpretation & conclusions: Our study findings highlighted a possible association of relative dehydration, as indicated by BUN/creatinine ratio >15, with END along with other parameters like stroke severity at presentation, extent of hypodensity >1/3 rd of the middle cerebral artery (MCA) territory and cerebral oedema. Dehydration being a treatable condition, the use of BUN/creatinine >15 as a marker of relative dehydration, can be helpful in detecting patients with dehydration early and thus play a role in preventing END.

    Abstract Ultra-short photoperiods, of 3 h less than the threshold photoperiodic demand of female redheaded bunting, when used in variable time cycles (T cycles) cause ovarian growth and an increase in body weight depending upon the period of the cycle. The cycles of period 24 h or close to that (22 h and 26 h) were non-stimulatory whereas 18 h, 20 h, 28 h and 30 h were photo-stimulatory. These results indicate the presence of a circadian component within the bird which regulates their photoperiodic responses.

    Abstract The photoperiodic response of female redheaded bunting (Emberiza bruniceps) was investigated in photosensitive and photorefractory birds exposed to resonance lighting cycles. Ovarian growth was stimulated in resonance cycles where light was present during the predicted photoinducible phase. Photorefractoriness was dissipated by resonance cycles in which light did not fall at times corresponding to the photoinducible phase. It is concluded that photosensitive and photorefractory female redheaded bunting monitor the photoperiodic time by means of a circadian rhythm.
