Pulmonary embolism (PE) is an age-related disorder which is potentially fatal, but frequently misdiagnosed. However, the true prevalence of pulmonary embolism is unknown. Inaccurate estimates of PE prevalence might, in part, be attributable to underrecognition of atypical presentations of this disorder. If true prevalence is unknown, the positive predictive values of both typical and atypical symptoms and signs of PE will be unreliable. The negative predictive value of those parameters will, likewise, be unreliable. The aim of this review is to make clinicians more aware of atypical manifestations of PE, thereby increasing the likelihood of correct diagnosis and, hence, ascertainment of the true prevalence of PE. The range of atypical manifestations was explored by a literature search, using MEDLINE from 1946 to February 2019, and EMBASE, from 1947 to February 2019, and Pubmed, from February 2014 to February 2019, using the search terms atypical, uncommon, unusual, pulmonary embolism, lung embolism, pulmonary thromboembolism. This search revealed atypical presenting features such as non pleuritic retrosternal pain, abdominal pain, atypical breathing patterns, pulmonary oedema, Dressler’s syndrome, atypical radiographic manifestations, atypical electrocardiographic features, manifestations associated with oxygen saturation of 95% or more, coexistence of acute myocardial infarction and pulmonary embolism, coexistence of thoracic aortic dissection and pulmonary embolism, neurological manifestations other than stroke, paradoxical embolism, acute venous thrombosis of atypical location, and pulmonary embolism with normal D-dimer levels.

Dissecting aortic aneurysm with ST segment elevation, and pulmonary embolism with ST segment elevation are two of a number of clinical entities which can simulate ST segment elevation myocardial infarction. Objective: The purpose of this review is to analyse clinical features in anecdotal reports of 138 dissecting aortic aneurysm patients with STEMI-like presentation, and 102 pulmonary embolism patients with STEMI-like presentation in order to generate insights which might help to optimise triage of patients with STEMI-like clinical presentation. Methods: Reports were culled from a literature search covering the period January 2000 to March 2020 using Googlescholar, Pubmed, EMBASE and MEDLINE. Reports were included only if there was a specification of the location of ST segment elevation and an account of the clinical signs and symptoms. Search terms were “ST segment elevation”,”aortic dissection”, “pulmonary embolism”, “myocardial infarction”, and “paradoxical embolism”. Fisher’s exact test was utilised for two-sided comparison of proportions. Proportion was calculated for each group as the number of patients with that parameter relative to the total number of patients assessed for that parameter. Findings: There were 138 patients with aortic dissection, 91 of whom were either fast-tracked to coronary angiography (81 patients) or fast-tracked to thrombolytic treatment (10 patients). There were 47 patients managed with neither of those strategies. There were 102 patients with pulmonary embolism, 71 of whom were fast tracked to coronary angiography, and 31 who did not receive that evaluation. Compared with their dissecting aortic aneurysm counterparts, those dissecting aortic aneurysm patients initially managed by percutaneous coronary intervention or by thrombolysis were significantly (p = 0.0003) more likely to have presented with chest pain, and significantly (p = 0.018) less likely to have presented with breathlessness. The preferential fast-tracking to coronary angiography prevailed in spite of comparable prevalence of back pain in fast tracked and in non-fast tracked subjects. Use of transthoracic echocardiography was also comparable in the two subgroups of dissecting aortic aneurysm patients. Pulmonary embolism patients fast tracked to percutaneous coronary intervention were significantly (p = 0.0008) more likely to have presented with chest pain than their pulmonary embolism counterparts who were not fast-tracked. The prevalence of paradoxical embolism was also significantly (p = 0.0016) higher in fast-tracked patients than in counterparts not fast-tracked. Cardiac arrest was significantly (p = 0.0177) less prevalent in fast-tracked pulmonary embolism patients than in pulmonary embolism patients who were not fast-tracked. Preferential fast-tracking to coronary angiography prevailed in spite of the fact that prevalence of documented deep vein thrombosis was comparable in fast-tracked subjects and in subjects not fast-tracked. The prevalence of use of transthoracic echocardiography was also similar in fast-tracked pulmonary embolism patients vs counterparts not fast tracked. Overall, however, transthoracic echocardiography had been utilised significantly (p = 0.007) less frequently in dissecting aneurysm patients than in pulmonary embolism patients. Conclusion: Given the high prevalence of STEMI-like presentation in aortic dissection there is a need for greater use of point-of-care transthoracic echocardiography to mitigate risk of inappropriate percutaneous coronary intervention(which might delay implementation of aortic repair surgery) and inappropriate thrombolysis(which might precipitate hemorrhagic cardiac tamponade) (75) during triage of patients presenting with ST segment elevation simulating ST segment elevation myocardial infarction (STEMI). Furthermore, during triage of patients with STEMI-like clinical presentation, the combined use of point-of -care echocardiography and evaluation for deep vein thrombosis will facilitate the differentiation between acute myocardial infarction, STEMI-like aortic dissection, and STEMI-like pulmonary embolism. Among STEMI-like patients in whom DAA has been ruled out by point of care TTE, fast tracking to PCI might generate an opportunity to identify and treat paradoxical coronary artery embolism by thrombectomy. Thereby mitigating the mortality risk associated with coronary occlusion. Concurrent awareness of PE as the underlying cause of paradoxical embolism also generates an opportunity to relieve the clot burden in the pulmonary circulation, either by pulmonary embolectomy or by thrombolysis. Above all, frontline clinicians should have a greater awareness of the syndrome of STEMI-like presentation of aortic dissection and STEMI-like pulmonary embolism so as to mitigate the risk of inappropriate thrombolysis and inappropriate percutaneous coronary angiography which seems to prevail even in the presence of red flags such as back pain (for aortic dissection) and deep vein thrombosis(for pulmonary embolism). 

The main purpose of the present study was to find out the differences on suicidal ideation, hostility, hopelessness and negative self-evaluation among heroin addicts with comorbid depression. After reviewing the literature, it was hypothesized that heroin addicts with high depression may have high scores on variable of suicidal ideation, hostility, hopelessness, and negative self-evaluation as compared to those with low depression. The sample was consisted of 60 males from Low-socioeconomic status (SES) (34 of them were screened as having high scores on the variable of depression and 26 were screened as low scorers). Siddiqui Shah Depression Scale (Siddiqui & Shah, 1997) and Urdu version of Suicide Probability Scale (Cull & Gill, 1982) was administered. To compare heroin addicts with high and low depression on various variables, t - test was applied. The research findings showed that heroin addicts with mean age of 30 years (range 20 to 40) having the mean duration of heroin dependence of 10 years with high depression were significantly high on the variable of suicidal ideation, hostility and hopelessness ((p < .05) as compared to those with low depression. And there was no significant difference on the variable of negative self-evaluation for both groups (p > .05). So it was concluded that services for patients with Heroin addiction should include periodic screening for suicidal behavior along with psychiatric treatment and psychosocial support.

Sepsis refers to a generalized inflammatory response of the organism to an infection or to bacterial products in circulation, rather than the development of an infection per se. Despite recent advances in clinical practice and overall medical care, sepsis remains a great health care problem and is still the most common cause of death in critically ill patients with infection. We suppose that during the course of sepsis the expression of TRAIL in different organs correlates with acute mortality and further development of multiple organ dysfunction syndrome (MODS). It is expected that dendritic cells (DCs) might become targets for apoptotic processes in a result of elevated TRAIL expression. This hypothesis is a bias for detailed investigations for in vivo studies in animal models and for in vitro studies of septic patients.

Biomarkers have been used in the diagnosis of disease and other conditions for many decades. There are diverse ranges of analytical targets, including metabolites, nucleic acids and proteins were used as a biomarker. Clinical diagnoses already rely heavily on these for patient disease classification, management, and informing treatment and care pathways. For that there is always a need of rapid and point of care test. However, until fairly recently, studies of biomarker efficacy in a clinical setting were mainly limited to single or dual use, and the landscape was complex, confused, and often inconsistent. Few candidates emerged from this somewhat clouded picture: C-reactive protein, procalcitonin (PCT) for sepsis, ADA for mycobacterium tuberculosis and a Circulating miRNAs serve as molecular markers for diverse physiological and pathological conditions.

This study investigated the water quality of tanker waters that was collected from Bengaluru urban areas to assess its suitability for domestic purpose. A total of 50 samples were collected in dry (March 2019) season. All samples were analyzed for various hydrochemical parameters, such as pH, total dissolved solids (TDS), electrical conductivity (EC), turbidity, dissolved oxygen (DO), total hardness (as CaCO3), calcium (CaCO2+), chloride (CaCO−) and nitrate (NO3−). Bacteriological analyses of water samples were analyzed for total coliform count. A very high level of total hardness (186 - 434.6 mg L-1) was determined in 27 water samples tested in this study indicating the necessity of water treatment before used for domestic purpose. Of the 50 samples tested, 7 showed a most probable number (MPN) index of < 23 and 9 showed < 240 and the remaining 34 were unsatisfactory with an MPN index of > 1600 per 100 ml. In some locations, the presence of high MPN index, in particular, rings the bell before using the tanker water in houses and restaurants. Exploration of the mechanisms by which water quality deteriorates during supply chain and potential implication for regulatory policy for monitoring of tanker water while distribution is the need of the hour.

We present a 54-year-old male with abdominal pain, Vomiting and weight loss since 5 months. Perforation was noted at recto-sigmoid junction and underwent Hartman’s procedure with end colostomy. Histology of sigmoid colon confirmed a Stercoral perforation without any evidence of dysplasia or malignancy. Patient had chemotherapy for squamous cell carcinoma (SCC) of epiglottis a year ago and was on codeine phosphate and Oromorph as and when required since his treatment for SCC for pain. Patient also had been suffering from constipation since he finished chemotherapy. Stercoral perforation always need to kept in mind in patients who present with constipation and need to take all patients who present with chronic constipation and initiate measures we encounter commonly in everyday practice. We present a brief review about Stercoral perforation and its management.

In this article different numerical techniques for solving optimal control problems is introduced, the aim of this paper is to achieve the best accuracy for the Optimal Control Problem (OCP) which has the objective of minimizing the size of tumor cells by the end of the treatment. An important aspect is considered, which is, the optimal concentrations of drugs that not affect the patient’s health significantly. To study the behavior of tumor growth, a mathematical model is used to simulate the dynamic behavior of tumors since it is difficult to prototype dynamic behavior of the tumor. A tumor-immune model with four components, namely, tumor cells, active cytotoxic T-cells (CTLs), helper T-cells, and a chemotherapeutic drug is used. Two general categories of optimal control methods which are indirect methods and direct ones based on nonlinear programming solvers and interior point algorithms are compared. Within the direct optimal control techniques, we review three different solutions techniques namely (i) multiple shooting methods, (ii) trapezoidal direct collocation method, (iii) Hermit- Simpson’s collocation method and within the indirect methods we review the Pontryagin’s Maximum principle with both collocation method and the backward forward sweep method. Results show that the direct methods achieved better control than indirect methods.

This research was conducted over period of 3 months with the aim of studying Age related changes of selected bones of forelimb (Scapula, Humerus, Radius and Ulna) in Local Mongrelian Dog (Canis lupus familiaris). The study entails biometrical and gross observations on the bones. The sample bones were acquired from the experimental animals of comparative anatomy in the department. The bones were categorized into various age groups for the research. The length, width, diameter and circumference of the samples (scapula, humerus, radius and ulna bones) were determined for all the groups. The shape, size, color, location, position and relation of each segment of the samples at various stages of development were determined. The differences across the age groups of different samples were observed and recorded. Based on the research result, it was concluded that, the biometric and morphometry data was found to be increasing with advancement of age. A baseline data was established with the view to enhance learning.

Nucleic acid-based therapy has become an increasingly important strategy for treating a variety of human diseases. In systemic therapy, a therapeutic gene must be delivered efficiently to its target tissues without side effects. To deliver a therapeutic gene such as plasmid DNA (pDNA) or small interfering RNA (siRNA) to target tissues by systemic administration, cationic carriers such as cationic liposomes and polymers have been commonly used as a non-viral vector. However, the binary complex of therapeutic gene and cationic carrier must be stabilized in the blood circulation by avoiding agglutination with blood components, because electrostatic interactions between positively charged complexes and negatively charged erythrocytes can cause agglutination, and the agglutinates contribute to high entrapment of the therapeutic genes in the highly extended lung capillaries. One promising approach for overcoming this problem is modification of the surface of cationic complexes with anionic biodegradable polymers such as hyaluronic acid, chondroitin sulfate, or polyglutamic acid. As another approach, we recently developed a sequential injection method of anionic polymer and cationic liposome/therapeutic gene complex (cationic lipoplex) for delivery of a therapeutic gene into the liver or liver metastasis. In this review, we describe recent advances in the delivery of therapeutic genes by lipid- and polymer-based carrier systems using anionic polymers.
