3,3′-(p-Phenyl­ene)bis­(3,4-dihydro-2H-1,3-benzoxazine)

Mol­ecules of the title compound, C22H20N2O2, are situated on crystallographic centres of symmetry. The oxazinane ring adopts a sofa conformation. Mol­ecules are linked into cyclic centrosymmetric dimers via C—H⋯O hydrogen bonds with the motif R 2 2(6). In addition to the C—H⋯O inter­actions, the crystal structure is also stabilized by C—H⋯π inter­actions

MIGRAINE: A POSSIBLE CAUSE FOR COGNITIVE DECLINE

Objectives:Migraine is the second most common type of headache and seventh most disabling disease worldwide. In general, obesity is often related to headache disorders in several clinical and epidemiologic studies. Obese migraine patients may have an increased attack frequency due to increase in inflammatory response. Cognitive decline is the major pitfall of migraine disorder and there exists a conflicting result between cognition and migraine and the effect of Body Mass Index (BMI) on migraine. So this study is done to find out the relationship between cognition and migraine and its association with BMI.Methods:The study protocol was approved by the ethical committee of SRM Medical College Hospital & Research Centre. The study group consisted of 30 migraine patients and 30 healthy controls aged between 18-40 years of age. Informed consent was obtained from all the participants. Diagnosis of migraine was made using the criteria of 2nd edition of International Headache Classification (IHC). Patients affected by Diabetes mellitus, Hypertension, allergy, inflammation, infection or immune disorders were excluded. Height and weight of the subjects were taken to calculate the BMI. Cognitive tests such as stroop interference trial & trial making tests (A&B) were done to evaluate working memory, mental flexibility and attention.Results:Compared to controls, cases took more time for performing stroop colour card test (106.40 ± 15.87 seconds vs. 132.17±7.027seconds, p<0.001) and trial making pattern B (54.77± 8.169 seconds vs. 56.23 ± 23.457seconds, p=0.004). Among the migraine subjects, obese individuals had an increased frequency of migraine attack per month (Correlation coefficient r=0.797)Conclusion:Cognitive decline in migraine is one of the underestimated problems in migraine. Identifying such problems early can prevent major consequences in day to day activities of migraine patients. Since there is an increased frequency of migraine with increase in BMI, obese migraine subjects can be recommended to do regular exercises.Â

Intelligent transportation system and smart traffic flow with IOT

64-67There has been an increase in vehicles across the globe. Also, the congestion due to traffic has leapfrogged in India. The traffic flow information has been required to find out the route with minimum congestion and forecast the traffic. And this has been a part of the Intelligent Transportation System (ITS) which would help build smart cities. A lot of work has been done on the traffic measurement system. But the integration of emerging techniques such as the Internet of Things (IoT) and cloud computing has provided a lot of research scope in ITS. This paper has proposed an IoT-based method to determine the real-time traffic flow in a road section with ultrasonic sensors, Arduino, ESP8266 Wi-Fi module, and an open-source cloud. There has been an average traffic flow every five minutes to be displayed in the cloud platform. This method can be very much cost-effective with less power consumption and improved accuracy. Hence, the proposed IoT-based technique has provided the traffic flow data, and this data shall further be used for traffic predictions using machine learning algorithms

"Profile of idiopathic intracranial hypertension in indian population - A prospective study "

Background. Idiopathic intracranial hypertension (IIH) also termed pseudotumor cerebri syndrome (PTCS). It mainly affects young overweight women of the reproductive age group. There is a scarcity of literature on IIH among the Indian population. Objective. To evaluate the clinical, demographic profile, laboratory parameters and outcomes of Idiopathic Intracranial hypertension (IIH) patients. Materials and method. The current study was a prospective observational study on 43 patients who were diagnosed as primary PTCS presenting to the neurology department of Sri Ramachandra Medical College and Research Institute from December 2019 to August 2021. Patients were assessed for BMI, papilledema, CSF manometry, MRI brain with MR venography was done. Co-guide software, V.1.03, was used for statistical analysis. Results. The mean age was 33.12 ± 12.29 years (ranged 14 to 55) in the study population. There were 5(11.63%) males and 38(88.37%) females. The mean BMI was 26.72 ± 3.56 kg/m2 (ranged from 17.40 to 34.20). The mean duration of headache was 28.41 ± 26.23 days (ranged 3 to 120) in the study population, and 39(90.69%) had papilledema. The mean CSF manometry was 29.6 ± 5.88(ranged from 16 to 42) cmH2O. Conclusion. In the Indian subcontinent, obesity may not be considered as a major risk factor in the causation of IIH

Mindbomb Homolog-1 Index in the Prognosis of High-Grade Glioma and Its Clinicopathological Correlation

Introduction: Gliomas are the most common brain tumors in adults originating from the glial cells. Glioblastoma multiforme is the most malignant and frequent among all gliomas. In recent years, the antibody Mindbomb Homolog-1 (MIB-1) has evolved as a measure of the proliferative nature of the glial tumors. This study aims to investigate the MIB-1 index value as an independent prognostic factor in high-grade gliomas and its correlation with outcome and survival. Materials and Methods: Mean MIB-1 index was determined in 51 high-grade glioma tissue samples in formalin. Its correlation with outcome by assessing the clinicoradiological parameters and median survival of patients in months were assessed. Survival analysis was studied by using the Kaplan–Meier bivariate analysis and Cox proportional ratio. Results: Preoperative Karnofsky Performance Score, WHO-PS, Neurological Performance Scale, and Mini–Mental Status Examination (MMSE) were statistically significant with respect to outcome and survival, whereas tumor factors such as size and perilesional edema were not. In particular, midline-crossing tumors and deep-seated tumors were significantly associated with high MIB-1 index and by correlation with outcome. There were significantly higher number (P < 0.0001) of patients with Grade IV tumors, with an MIB-1 index value above an arbitrary cutoff of 10% compared to Grade III tumors. In addition, median survival period of patients with low MIB-1 index was longer irrespective of tumor grade. Conclusion: Significant correlation between high-grade glioma and MIB-1 index suggests MIB-1 index to be a good prognostic tool, with MIB-1 index and midline-crossing variables being independent prognostic parameters
