Students' mental health during the pandemic: results of the observational cross-sectional COVID-19 MEntal health inTernational for university Students (COMET-S) study

Introduction

The aim of the study was to search rates of depression and mental health in university students, during the COVID-19 pandemic.

Materials and methods

This is an observational cross-sectional study. A protocol gathering sociodemographic variables as well as depression, anxiety and suicidality and conspiracism was assembled, and data were collected anonymously and online from April 2020 through March 2021. The sample included 12,488 subjects from 11 countries, of whom 9,026 were females (72.2%; aged 21.11 ± 2.53), 3,329 males (26.65%; aged 21.61 ± 2.81) and 133 "non-binary gender" (1.06%; aged 21.02 ± 2.98). The analysis included chi-square tests, correlation analysis, ANCOVA, multiple forward stepwise linear regression analysis and Relative Risk ratios.

Results

Dysphoria was present in 15.66% and probable depression in 25.81% of the total study sample. More than half reported increase in anxiety and depression and 6.34% in suicidality, while lifestyle changes were significant. The model developed explained 18.4% of the development of depression. Believing in conspiracy theories manifested a complex effect. Close to 25% was believing that the vaccines include a chip and almost 40% suggested that facemask wearing could be a method of socio-political control. Conspiracism was related to current depression but not to history of mental disorders.

Discussion

The current study reports that students are at high risk for depression during the COVID-19 pandemic and identified specific risk factors. It also suggested a role of believing in conspiracy theories. Further research is important, as it is targeted intervention in students' groups that are vulnerable both concerning mental health and conspiracism.

The sudden transition to remote learning in response to COVID-19: lessons from Malaysia

Higher education students are frequently required to assess lecturers with a convenient, fast, and anonymous learning management system. Following the coronavirus disease 2019 (COVID-19) pandemic outbreak, Universiti Teknologi MARA Malaysia (UiTM) adopted a remote teaching and learning approach. This study examined how lecturers' professionalism, course impression, and facilitating conditions at UiTM affected undergraduate and graduate students' remote learning pre- and mid-pandemic. The higher prediction accuracy of the model demonstrated that students' remote learning activities were highly related to lecturers' professionalism, course impression, and facilitating conditions. The structural model demonstrated that the t-statistics of all measurement variables were significant at 1%. The strongest predictor of students' enjoyment of remote learning pre- and mid-pandemic was lecturers' professionalism. In the importance-performance matrix, lecturers' professionalism was in the quadrant for 'keep up the good work'. Facilitating conditions and course impression did not require further improvement even during the pandemic. The influence of remote learning was demonstrated in the students' graduation rates and grades. The results also presented theoretical and practical implications for the UiTM hybrid learning plan post-pandemic.

The prognostic value of early follow-up computerized tomography of the brain in adult traumatic brain injury

A total of 31 adult patients with moderate and severe head injury were assessed clinically on admission for Glasgow Coma Scale (GCS) and short test of mental status (STMS) on follow-up and compared to their initial and follow up CT scan. Good predictors were admission GCS, midline shift, volume of subdural haemorrhage in the initial CT scan of the brain as well as the presence of post-traumatic hydrocephalus, gliosis and site of gliosis in the follow-up CT scan. There was no direct correlation between the significant predictors on the first CT scan and the follow-up CT scan of the brain.

A study of the factors related to intima-media thickness of the common carotid artery amongst rural middle age individuals in Hospital Universiti Sains Malaysia

There is very little data regarding the factors related to intima-media thickness (IMT) of the common carotid artery in normal individuals in those with non-insulin diabetes mellitus and perimenopausal women in Southeast Asian countries. Ultrasound imaging evaluating the carotid artery IMT in those with diabetes and those on hormone replacement therapy (HRT) was performed beginning in August 2000 for a period of nearly two years at the Department of Radiology, Hospital Universiti Sains Malaysia, Kubang Kerian, Kelantan, Malaysia. A total of 153 participants were included. Significant differences between the women on HRT and not on HRT were IMT and systolic blood pressure. When comparing those with non-insulin dependent diabetes mellitus (NIDDM) and normal individuals, the significant differences were IMT, total cholesterol level, systolic blood pressure and diastolic blood pressure. IMT was high in those with NIDDM but not in those on HRT. Both those with NIDDM and those on HRT had associated dyslipidemia and systolic hypertension.

Red flags in patients presenting with headache: clinical indications for neuroimaging

Headache is a very common patient complaint but secondary causes for headache are unusual. Neuroimaging is both expensive and has a low yield in this group. Most patients with intracranial pathology have clinical features that would raise a "red flag". Appropriate selection of patients with headache for neuroimaging to look for secondary causes is very important. Red flags act as screening tools to help in identifying those patients presenting with headache who would benefit from prompt neuroimaging, and may increase the yield. The aim of this study is to evaluate clinical features in patients with headache using neuroimaging as a screening tool for intracranial pathology. 20 red flags were defined. A retrospective study of 111 patients was performed and the outcomes were divided into positive and negative. Abnormal neuroimaging was present in 39 patients. Results were analysed using the Logistic Regression model. Sensitivity and specificity of red flags were analysed to establish the cut-off point to predict abnormal neuroimaging and a receiver operating characteristic (ROC) curve plotted to show the sensitivity of the diagnostic test. Three red flag features proved to be statistically significant with the p-value of less than 0.05 on both univariate and multivariate analysis. These were: paralysis; papilloedema; and "drowsiness, confusion, memory impairment and loss of consciousness". In addition, if three or more red flags from the list were present, this showed strong indication of abnormal neuroimaging, from cut-off point of ROC curve (area under the curve =0.76).

Multifocal mucus secreting papillary adenocarcinoma of the bile duct causing obstructive jaundice

We present a 64-year-old Malay lady who had undergone a choledochoduodenostomy (CDD) two years ago for obstructive jaundice. She was admitted with jaundice and underwent ultrasonography, percutaneous transhepatic cholangiography (PTC), endoscopic retrograde cholangio pancreatography (ERCP) and computed tomographic (CT) scanning of the liver and biliary tree. All the investigations confirmed a type IVa choledochal cyst. At operation, the grossly dilated biliary system was packed with a thick mucoid material and the mucosa of the bile ducts was visibly abnormal with scattered nodules. This mucoid material had caused occlusion of the entire biliary tree resulting in obstructive jaundice. To the best of our knowledge, this is probably the first report of obstructive jaundice caused by thick mucus. The peculiar management problems of this case and the risk of malignant change in choledochal cysts are discussed.
