RESUMO

INTRODUCTION: Gastrointestinal (GI) lipomas are rare; however, they are frequent enough to be considered in the differential diagnosis of gut tumours. Here, we present our experience with GI lipomas managed at our institute over the last three years. METHODS: This is a retrospective cohort study of patients with GI lipomas managed between January, 2020 and April, 2023 at a tertiary care centre. Clinical presentation, location, and details of surgical procedure were analysed. RESULTS: Ten patients were included, six of whom had lipoma in the colon, one in the stomach, and one each in the duodenum, jejunum, and ileum. The mean age at the time of presentation was 48.8 years (range, 19-77 years), and strong male preponderance (4:1) was noted. Preoperative diagnosis of lipoma on cross-sectional imaging was possible in all patients. All patients were symptomatic and were managed surgically. CONCLUSIONS: While GI lipomas are generally considered to be indolent and benign tumours, they can potentially lead to severe complications. The utilisation of computed tomography and magnetic resonance imaging has brought about a significant transformation in diagnosing this condition, enabling preoperative identification in most cases. The surgery offers a definitive treatment with minimal risk of postoperative complications.

RESUMO

We present the first fully analytic evaluation of the transition amplitude for the scattering of a massless into a massive pair of fermions at the two-loop level in quantum electrodynamics. Our result is an essential ingredient for the determination of the electromagnetic coupling within scattering reactions, beyond the currently known accuracy, which has a crucial impact on the evaluation of the anomalous magnetic moment of the muon. It will allow, in particular, for a precise determination of the leading hadronic contribution to the (g-2)_{µ} in the MUonE experiment at CERN, and therefore can be used to shed light on the current discrepancy between the standard model prediction and the experimental measurement for this important physical observable.

RESUMO

BACKGROUND: Plastic containers are widely used to store and serve edibles. In the production of some types of plastic, chemicals such as bisphenol A (BPA) and bisphenol S (BPS) are used. These chemicals leach from the plastic containers into the edibles, get access into the biological systems, and cause a toxic impact on health. AIM: This cross-sectional survey was planned to assess the usage of food contact plastic and awareness regarding the health hazards of plastic chemicals and warning labels on plastic items among a sample population of Varanasi city. MATERIALS AND METHODS: Data were collected by interviewing the 556 adult participants, using a prevalidated structured questionnaire. Chi-square test was used to test the association and P < 0.05 was considered as significant. RESULTS: Most of the participants were found to be following routine practices during cooking and storage of edibles which may expose them to BPA and BPS through the gut. Although many participants were aware that plastic may contain some type of chemicals which may enter the human body and harm human health in some way, they lacked precise knowledge regarding warning label like "BPA free plastic" "plastic containing BPA" and "food grade plastic." Furthermore, none of the participants could recognize the "resin identification codes" correctly. CONCLUSION: Most of the participants had only elementary awareness of health risk of plastic usage. A significant number of participants lacked crucial information that can help them to make healthy choices as a consumer and use safe alternatives of plastic.

RESUMO

Heart failure (HF) is becoming an increasingly prevalent healthcare problem. Besides, Ischemic heart disease (IHD) and Hypertension (HTN), there is a number of other factors that continue to evolve as risk factors for heart failure. The aim of the study was to identify the different risk factors of heart failure patients. This case-control study was conducted in the Department of Cardiology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from August 2014 to July 2015. It was included 75 patients of heart failure (cases) and 75 age and sex matched adult individuals (friends and relations of heart failure cases) as controls. The risk factors studied were grouped into demographic, clinical, behavioral and biochemical variables. The age distribution between case and control groups was almost identical with mean ages of either group being 55 years (p=0.922). The sex distribution was also fairly comparable with male being predominant in both the groups (p=0.574). In this study IHD followed by uncontrolled hypertension (p=0.001) are came out to be the predominant risk factors of heart failure followed by smoking and obesity (p<0.001). From the findings of the study, it can be concluded that a number of risk factors are involved in heart failure cases. Of them ischemic heart disease and uncontrolled hypertension are the predominant ones followed by smoking and obesity. The best strategy would, therefore, be to treat and control ischemic heart disease, hypertension, obesity, diabetes and smoking habit in the population. However, as the risk factors in the population continue to change; ongoing surveillance is important to guide right preventive strategy in future.

RESUMO

An echocardiographic investigation is one of the key modalities of diagnosis in cardiology. There has been a rising presence of cardiological comorbidities in patients positive for COVID-19. Hence, it is becoming extremely essential to look into the correct safety precautions, healthcare professionals must take while conducting an echo investigation. The decision matrix formulated for conducting an echocardiographic evaluation is based on presence or absence of cardiological comorbidity vis-à-vis positive, suspected or negative for COVID-19. The safety measures have been constructed keeping in mind the current safety precautions by WHO, CDC and MoHFW, India.

RESUMO

The physiology of baroreceptors and chemoreceptors present in large blood vessels of the heart is well known in the regulation of cardiorespiratory functions. Since large blood vessels and peripheral blood vessels are of the same mesodermal origin, therefore, involvement of the latter in the regulation of cardiorespiratory system is expected. The role of perivascular nerves in mediating cardiorespiratory alterations produced after intra-arterial injection of a nociceptive agent (bradykinin) was examined in urethane-anesthetized male rats. Respiratory frequency, blood pressure, and heart rate were recorded for 30 min after the retrograde injection of bradykinin/saline into the femoral artery. In addition, paw edema was determined and water content was expressed as percentage of wet weight. Injection of bradykinin produced immediate tachypneic, hypotensive and bradycardiac responses of shorter latency (5-8 s) favoring the neural mechanisms involved in it. Injection of equi-volume of saline did not produce any responses and served as time-matched control. Paw edema was observed in the ipsilateral hind limb. Pretreatment with diclofenac sodium significantly attenuated the bradykinin-induced responses and also blocked the paw edema. Ipsilateral femoral and sciatic nerve sectioning attenuated bradykinin-induced responses significantly, indicating the origin of responses from the local vascular bed. Administration of bradykinin in the segment of an artery produced reflex cardiorespiratory changes by stimulating the perivascular nociceptors involving prostaglandins. This is a novel study exhibiting the role of peripheral blood vessels in the regulation of the cardiorespiratory system.

RESUMO

The unprecedented and rapidly spreading Coronavirus Disease-19 (COVID-19) pandemic has challenged public health care systems globally. Based on worldwide experience, India has initiated a nationwide lockdown to prevent the exponential surge of cases. During COVID-19, management of cardiovascular emergencies like acute Myocardial Infarction (MI) may be compromised. Cardiological Society of India (CSI) has ventured in this moment of crisis to evolve a consensus document for care of acute MI. However, this care should be individualized, based on local expertise and governmental advisories.
