Similarities and differences in the prevalence and risk factors of suicidal behavior between caregivers and people with dementia: a systematic review.

BACKGROUND: People with dementia and their caregivers are prone to suicidal behaviors due to difficulty adjusting to their initial caregiving role and due to emotional disturbances resulting from deterioration of functioning. The present systematic review (1) explored the prevalence of and risk factors for suicidal behavior and (2) assessed the similarities and differences in the prevalence and risk factors for suicidal behavior between people with dementia and their caregivers. METHODS: A comprehensive literature search for research articles published between 1950 and 2023 was carried out using major databases, such as Google Scholar, Web of Science, PubMed, Scopus, PsycINFO, EMBASE, the Cochrane Library, and Medline. RESULTS: A total of 40 research articles were selected for review. A total of 12 research articles revealed that the prevalence of suicidal behavior among caregivers ranged from 4.7% to 26%. However, the risk of suicidal behavior among people with dementia was inconsistent, as only 17 out of 28 selected studies reported the risk of suicidal behavior among people with dementia. The risk factors associated with suicidal behavior among caregivers of people with dementia could be both self-related and care receiver-related factors, whereas risk factors in people with dementia were self-related factors. Notably, greater cognitive decline, which impairs individuals' ability to carry out complex acts and planning, may lower their suicidal risk. Finally, assessment of the risk of bias indicated that 95% of the selected studies had unclear risk. CONCLUSION: Self-related and care receiver-related factors should be assessed among caregivers of people with dementia to evaluate the risk of suicidal behavior. In addition, we recommend evaluating suicidal risk in people with dementia in the early phase of dementia when cognitive decline is less severe. However, as the majority of the selected studies had unclear risk of bias, future studies with improved methodologies are warranted to confirm our study findings.

Psychometric properties of the Malay version of the Illness Cognition Questionnaire among cancer patients in Malaysia.

OBJECTIVE: The Illness Cognition Questionnaire (ICQ) was translated from its original English version to the Malay version for this research, adapted the Malay language version of the ICQ (ICQ-M) for use in cancer patients, and assessed the internal consistency, content, face, construct, convergent, discriminant and concurrent validity of the ICQ-M among a cohort of cancer patients with mixed cancer types in Malaysia. METHOD: Initially, the ICQ was translated into Malay and back-translated, and its content and face validity were evaluated. Then, 346 cancer patients with various cancer types received the ICQ-M, and its internal consistency, convergent, discriminant, construct, and concurrent validity were evaluated. RESULTS: The ICQ-M and its domains had acceptable internal consistency with Cronbach's α ranging from 0.742 to 0.927. Construct validity assessment demonstrated that the ICQ-M consists of 17 items designated in two domains with good convergent and discriminant validity. The ICQ-M and its domains also had moderate correlations with the Acceptance and Action Questionnaire II, which denotes that the ICQ-M had acceptable concurrent validity. CONCLUSION: The ICQ-M had good psychometric properties and is now available to measure the illness cognition of cancer patients in Malaysia.

Does hematology rotation impact the interest of internal medicine residents in considering hematology as a career?

BACKGROUND: The ongoing need for hematologists is not met in many parts of the world. The hematology rotation during internal medicine residency is an opportunity to attract more physicians to the hematology field. This study aimed to assess the impact of a hematology rotation on internal medicine residents' interest in considering a hematology career. METHODS: Internal medicine residents were invited to complete an anonymous questionnaire before and after a mandatory hematology rotation. Their interest in pursuing a hematology career was assessed by asking them to rate "Consider hematology as a career" on a 0 to 10 scale (0 = never, 10 = strongly agree). In addition, viewing the hematology workload as manageable, comfort in dealing with cancer and satisfaction with the hematologist lifestyle were assessed before and after the rotation. RESULTS: Sixty out of 62 IM residents completed the pre- and post-hematology rotation questionnaire (response rate 97%). 80% were in the age range of 25-29 years and 73% were males. Two-thirds were in the senior level (3rd and 4th year) of their residency program and 40% had a prior rotation in a hematology unit. Rating considering hematology as a career increased significantly from a median of 7 (IQR: 5-9) pre-rotation to 8.5 (IQR: 7-10) post-rotation (p = 0.0018). Subgroup analysis showed a significant increase in interest among subgroups except residents > 29 years of age, those with prior hematology rotation and junior residents (1st and 2nd year residency). The change in viewing hematology workload as manageable, comfort in dealing with cancer patients and perceiving the hematologist lifestyle as satisfactory were strongly positively correlated with the change in considering hematology as a career (p = 0.0014, < 0.0001 and < 0.0001; respectively). CONCLUSIONS: A hematology rotation is associated with an increase in the interest of internal medicine residents in considering hematology as a career. Further research is needed to Identify factors that may make hematology rotations an effective tool in attracting residents to the hematology field.

Prospective cohort study of unmet supportive care needs, post-traumatic growth, coping strategy and social supports among patients with breast cancer: The PenBCNeeds study.

PURPOSE: While the unmet healthcare needs are still being improved upon, the wellbeing of cancer patients has increasingly become a prime concern in Malaysia. The objective of this study is to ascertain the trend of unmet supportive care needs, post-traumatic growth (P T G), coping strategies, and social supports among patients with breast cancer over the three time points of treatment: T1 at early diagnosis, T2 for three months after diagnosis, and T3 for six months after diagnosis. METHODS: A total of 240 cancer patients participated in this prospective cohort study, with follow-up visits from October 2019 until July 2021. Data were collected using several instruments: Brief COP E, the Source of Social Support Scale (SSSS), the Post-Traumatic Growth Inventory - Short Form (P T GI-SF), and a Malay version of the 34-Item Shortform Supportive Care Need Survey (SCNS-SF34). RESULTS: The results indicated a significant change from T1 to T3 for all domains of the unmet needs (p-value < 0.001), except for the sexual domain. A lower SCNS-SF34 score resulted from more unfavorable social support. The P T GI-SF results indicated a trend toward meeting the unmet needs, and a higher SCNS-SF-34 score predicted a considerably higher P T GI-SF score. CONCLUSIONS: Our study findings suggest that majority of the factors evaluated in terms of unmet needs among cancer patients have undergone considerable changes.

Geopolitical risk and firm-level environmental, social and governance (ESG) performance.

This study investigates the impact of geopolitical risk on firm-level environmental, social, and governance (ESG) performance. Using a news-based indicator of geopolitical risk across 41 countries and a comprehensive dataset spanning from 2002 to 2021 with 65,354 firm-year observations, we uncover that geopolitical risk is negatively associated with ESG performance. Our findings remain robust even when considering alternative measures of geopolitical risk, ESG components, and sub-samples. Moreover, we address potential endogeneity concerns through two-stage least squares, propensity score matching and entropy balancing approaches. Interestingly, we find that the effect of geopolitical risk is positive for countries with lower geopolitical risk and high peace, indicating that relatively stable environments can incentivize firms to enhance their sustainability practices. We also examine the potential channel effects of cash holding, corporate investment, and cost of capital, and found significant effects. Overall, this paper underscores the significance of geopolitical risk as a macro-level shock that significantly influences ESG performance.

An Overview of Pulses Production in India: Retrospect and Prospects of the Future Food with an Application of Hybrid Models.

Forecasts are valuable to countries to make informed business decisions and develop data-driven strategies. The production of pulses is an integral part of agricultural diversification initiatives because it offers promising economic opportunities to reduce rural poverty and unemployment in developing countries. Pulses are the cheapest source of protein needed for human health. India's pulses production guidelines must be based on accurate and best forecast models. Comparing classical statistical and machine learning models based on different scientific data series is the subject of high-level research today. This study focused on the forecasting behaviour of pulses production for India, Karnataka, Madhya Pradesh, Maharashtra, Rajasthan and Uttar Pradesh. The data series was split into a training dataset (1950-2014) and a testing dataset (2015-2019) for model building and validation purposes, respectively. ARIMA, NNAR and hybrid models were used and compared on training and validation datasets based on goodness of fit (RMSE, MAE and MASE). This research demonstrates that due to the diverse agricultural conditions across different provinces in India, there is no single model that can accurately predict pulse production in all regions. This study's highest accuracy model is ARIMA. ARIMA outperforms NNAR, a machine learning model. Pulse production in India, Rajasthan, and Madhya Pradesh will expand by 26.11%, 12.62%, and 0.51% from 2020 to 2030, whereas it would decline by - 6.5%, - 6.21%, and - 6.76 per cent in Karnataka, Maharashtra, and Uttar Pradesh, respectively. The current forecast results could allow policymakers to develop more aggressive food security and sustainability plans and better Indian pulses production policies in the future.

A longitudinal investigation of posttraumatic growth and its associated factors among head and neck cancer survivors.

OBJECTIVES: Posttraumatic growth (PTG) may improve well-being among cancer survivors, but a longitudinal study addressing head and neck cancer (HNC) is lacking. This longitudinal study examined PTG trends and determined the associations of physical symptoms and complications, as well as sociodemographic and tumor characteristics on PTG over time among HNC survivors. METHODS: Participants completed the European Organization of Research and Treatment of Cancer's "Quality of Life Questionnaire-Head and Neck 35" module (EORTC-QLQ-H&N-35) and "Posttraumatic Growth Inventory-Short Form" (PTGI-SF) during baseline (T1 ) and follow-up (T2 ; 5-7 months post-baseline) assessments. RESULTS: In total, 200 HNC participants completed the study and 67.5% of them reported increasing PTG. Physical symptoms and complications that were significantly associated with lower PTG included problems with social contact and the senses. Meanwhile, sociodemographic variables that were significantly associated with PTG were gender (males had lower PTG than females) and religion (Muslims and Buddhists had higher PTG than participants of other religious faith). CONCLUSION: Our findings revealed the need to focus on the impact of sensory issues and reduced social contact following HNC on PTG which may be addressed by various restorative and supportive rehabilitation therapy.

Life cycle assessment of biodiesel production by using impregnated magnetic biochar derived from waste palm kernel shell.

Biodiesel is renewable, biodegradable, biocompatible (non-toxic) and environmentally friendly, which emits less pollution than traditional fossil-based diesel, making it the most promising and ideal option. However, biodiesel is facing many current issues, mostly related to the utilisation of homogeneous catalytic technology, and this circumstance obstructs its potential development and advancement. Therefore, new pathways for biodiesel production need to be explored, and the aforementioned issues need to be addressed. Recently, a study was conducted on the impregnated magnetic biochar derived from a waste palm kernel shell (PKS) catalyst that can replace conventional catalysts due to its reusability property. Nevertheless, the environmental impacts of impregnated magnetic biochar derived from waste PKS catalyst for biodiesel production are yet to be studied. This study focuses on the evaluation of the life cycle assessment (LCA) of palm-based cooking oil for biodiesel production catalysed by impregnated magnetic biochar derived from waste PKS. Simapro was used in this study to evaluate the impact assessment methodologies. Case 1 (6.64 × 102 Pt) has contributed less to environmental impacts than Case 2 (1.83 × 103 Pt). This indicates purchasing refined palm oil for biodiesel production may reduce environmental impacts by 64% compared to producing biodiesel from raw fruit bunches. In the midpoint assessment, the transesterification process was identified as the hotspot and marine aquatic ecotoxicity as the highest impact category with a value of 1.00 × 106 kg 1,4-DB eq for 1 tonne of biodiesel produced. The endpoint results showed that Case 1 revealed the greatest impact on the transesterification process, with cumulative damage of 461 Pt. Scenario without processing the raw palm fruit bunches to obtained palm oil was better than Case 2. Further research should be conducted on life cycle cost and sensitivity analysis to evaluate the economic feasibility and promote sustainable biodiesel production.

Evaluation of growth and some unexplored bioactivities of bioreactor grown adventitious root culture of ginseng (Panax ginseng C.A. Meyer).

The purpose of the present study was to evaluate the growth potential and some rarely reported bioactivities (antioxidant, thrombolytic, anticoagulant, and anthelmintic) of Panax ginseng C.A. Meyer adventitious roots. To demonstrate the growth, shake flask and laboratory-scale bioreactor cultures have been employed. The obtained biomass was dried and extracted with water, ethanol, and methanol. The growth ratio (12.62 ± 1.03) observed in the bioreactor was significantly higher than in the shake flask culture. The presence of 10 different phytochemical classes, including carbohydrates, saponins, glycosides, and terpenoids were detected in qualitative estimation. Significant quantities of phenolics, flavonoids, proteins, and tannins were determined. Dose-dependent antioxidant activities were observed, and the IC50 values of methanolic and ethanolic extracts were very similar to the standard. The highest (29.26 ± 5.31%) thrombolytic potential was shown by the methanolic extract. The ethanolic extract significantly extended the coagulation times up to 2.5 fold. The highest anthelmintic properties in terms of paralyzing (2.21 ± 0.31 min) and killing (3.69 ± 0.41 min) of the parasitic worms were displayed by the aqueous extract. The in vitro root growth implies the commercial feasibility of ginseng production in Bangladesh and the demonstration of potential bioactivities strengthens medicinal implications and also offering new research areas.

The Association of RGS2 and Slug in the Androgen-induced Acquisition of Mesenchymal Features of Breast MDA-MB-453 Cancer Cells.

BACKGROUND: Epithelial-mesenchymal transition (EMT) of tumor cells is a prerequisite to cancer cell invasion and metastasis. This process involves a network of molecular alterations. Androgen receptor (AR) plays an important role in the biology of breast cancers, particularly those dependent on AR expression like luminal AR (LAR) breast cancer subtype. We have recently reported that the AR agonist, dihydrotestosterone (DHT), induces a mesenchymal transition of MDA-MB-453 cells, concomitant with transcriptional up-regulation of Slug and regulator of G protein signaling 2 (RGS2). OBJECTIVE: The role of Slug and RGS2 in mediating the DHT-induced effects in these cells was investigated. METHODS: MDA-MB-453 cells were used as a model system of LAR breast cancer. Immunofluorescence was used to examine cell morphology and protein localization. Protein expression was analyzed by immunoblotting. Protein localization was confirmed by cell fractionation followed by immunoblotting. Protein-protein interaction was confirmed by co-immunoprecipitation followed by immunoblotting. Transwell membranes were used to assess cell migration. Transfection of cells with siRNA molecules that target Slug and RGS2 mRNA was utilized to delineate the modes of action of these two molecules. RESULTS: Treatment of MDA-MB-453 cells with DHT induced the expression of both proteins. In addition, AR-Slug, AR-RGS2, and Slug-RGS2 interactions were observed shortly after AR activation. Knocking down Slug abrogated the basal, but not the DHT-induced, cell migration and blocked DHT-induced mesenchymal transition. On the other hand, RGS2 knocked-down cells had an increased level of Slug protein and assumed mesenchymal cell morphology with induced migration, and the addition of DHT further elongated cell morphology and stimulated their migration. Inhibition of AR or ß-catenin reverted the RGS2 knocked-down cells to the epithelial phenotype, but only inhibition of AR blocked their DHT-induced migration. CONCLUSIONS: These results suggest the involvement of RGS2 and Slug in a complex molecular network regulating the DHT-induced mesenchymal features in MDA-MB-453 cells. The study may offer a better understanding of the biological role of AR in breast cancer toward devising AR-based therapeutic strategies.

Prevalence of and factors associated with insufficient physical activity among adolescents: evidence from a nationwide survey in Bangladesh.

The World Health Organization set a target of a 15% relative reduction in the prevalence of insufficient physical activity (IPA) by 2025 among adolescents and adults globally. In Bangladesh, there are no national estimates of the prevalence of IPA among adolescents. The aim of this study was to estimate the prevalence of and risk factors associated with IPA among adolescent girls and boys. Data for 4865 adolescent girls and 4907 adolescent boys, collected as a part of a National Nutrition Surveillance in 2018-19, were analysed for this study. A modified version of the Global Physical Activity Questionnaire (GPAQ) was used to collect physical activity data. The World Health Organization recommended cut-off points were used to estimate the prevalence of IPA. Bivariate and multivariable logistic regression was performed to identify factors associated with IPA. Prevalences of IPA among adolescent girls and boys were 50.3% and 29.0%, respectively, and the prevalence was significantly higher among early adolescents (10-14 years) than late adolescents (15-19 years) among both boys and girls. The IPA prevalence was highest among adolescents living in non-slum urban areas (girls: 77.7%; boys: 64.1%). For both boys and girls, younger age, non-slum urban residence, higher paternal education and increased television viewing time were significantly associated with IPA. Additionally, residing in slums was significantly associated with IPA only among the boys. Higher maternal education was associated with IPA only among the girls. This study identified several modifiable risk factors associated with IPA among adolescent boys and girls in Bangladesh. These factors should be addressed through comprehensive public health interventions to promote physical activity among adolescent girls and boys.

The online learning experience and reported headaches associated with screen exposure time among Saudi health sciences students during the COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic has become a global health issue and has significantly impacted university education. As a result, learning methods have been shifted to be delivered through online learning. Online learning has increased reliance on computer screens, which can cause visual discomfort and may cause or exacerbate headaches due to prolonged screen exposure. However, time spent using electronic devices has not yet been examined in relation to the online learning experience. PURPOSE: This study assessed the online learning experiences and reported headaches associated with screen exposure time among health sciences university students. METHODS: A cross-sectional study was conducted among a convenience sample of 353 students at Saudi University. Online learning experiences, screen time exposure, and reported headache questionnaires were used to collect the data. RESULTS: Students were moderately satisfied with the online learning experience. Nevertheless, they faced many challenges with online learning that affected their communication efficacy, and they preferred that blended learning be continued. In addition, this study found a high prevalence of headache (65.72%) and a high screen exposure time among the studied students (52.69%). Increased screen time exposure is linked with increased headache and migraine reporting among students (p < 0.05). CONCLUSION: Headache is a common health issue among health professional students, and it can harm their academic performance and quality of life, especially related to online learning. Greater awareness of headaches, stress reduction and prevention programs, and ergonomic practices to deal with headaches are essential. Blended learning approaches can improve student learning and performance in health science courses.

Enrichment of Neurodegenerative Microglia Signature in Brain-Derived Extracellular Vesicles Isolated from Alzheimer's Disease Mouse Models.

Extracellular vesicles (EVs) are secreted by any neural cells in the central nervous system for molecular clearance, cellular communications, and disease spread in multiple neurodegenerative diseases, including Alzheimer's disease (AD), although their exact molecular mechanism is poorly understood. We hypothesize that high-resolution proteomic profiling of EVs separated from animal models of AD would determine the composition of EV contents and their cellular origin. Here, we examined recently developed transgenic mice (CAST.APP/PS1), which express familial AD-linked mutations of amyloid precursor protein (APP) and presenilin-1 (PS1) in the CAST/EiJ mouse strain and develop hippocampal neurodegeneration. Quantitative proteomics analysis of EVs separated from CAST.APP/PS1 and age-matched control mice by tandem mass tag-mass spectrometry identified a total of 3444 unique proteins, which are enriched in neuron-, astrocyte-, oligodendrocyte-, and microglia-specific molecules. CAST.APP/PS1-derived EVs show significant enrichment of Psen1, APP, and Itgax and reduction of Wdr61, Pmpca, Aldh1a2, Calu, Anp32b, Actn4, and Ndufv2 compared to WT-derived EVs, suggesting the involvement of Aß-processing complex and disease-associated/neurodegenerative microglia (DAM/MGnD) in EV secretion. In addition, Itgax and Apoe, DAM/MGnD markers, in EVs show a positive correlation with Itgax and Apoe mRNA expression from brain tissue in CAST.APP/PS1 mice. These datasets indicate the significant contribution of Aß plaque and neurodegeneration-induced DAM/MGnD microglia for EV secretion in CAST.APP/PS1 mice and shed light on understanding AD pathogenesis.

Influence on attitudes and lifestyle due to lockdown amidst COVID-19 pandemic: a perception-based analysis among Bangladeshi residents.

BACKGROUND: Countrywide lockdown or stay-at-home order has been implemented to slow down the transmission of emergent coronavirus. However, the influence on attitudes and lifestyle due to lockdown amidst the coronavirus disease 2019 (COVID-19) pandemic has been poorly understood. The present study aimed to investigate the influence on attitudes and lifestyle due to lockdown amidst the COVID-19 pandemic among Bangladeshi residents. METHODS: A cross-sectional survey carried out involving 1635 community dwellers across eight divisions in Bangladesh conducted from April 15, 2020 to May 10, 2020. A structured questionnaire incorporating socio-demographic, attitudes towards lockdown and adverse lifestyle amidst lockdown measures was employed to collect data using the Google Forms. Multiple regression analyses were executed to determine the associated factors of positive attitudes towards lockdown and adverse lifestyle. RESULTS: The mean scores of attitudes towards lockdown were 67.9 (SD = 8.4) out of 85 with an overall correct rate (positive attitudes) of 79.9%; whereas the mean scores of adverse lifestyle amidst lockdown were 16.1 (SD = 4.8) out of 34 with an overall rate of 47.4%. The factors associated with more positive attitudes towards lockdown included being female, divorced, higher educated, and students. Conversely, being male, having no formal education, and rural residence were associated factors of adverse lifestyle amidst the COVID-19 pandemic. CONCLUSIONS: The findings reflect how the COVID-19 lockdown has preciously impacted the attitudes, and lifestyle of Bangladeshi citizens, which will contribute to promoting appropriate measures during a subsequent zonal or complete lockdown.

Involvement of ß-catenin in Androgen-induced Mesenchymal Transition of Breast MDA-MB-453 Cancer Cells.

Purpose The cellular and molecular dynamics of DHT-induced EMT in MDA-MB-453 cells were investigated.Methods:PCR arrays were used to examine the expression of EMT-regulatory genes. Immunoblotting was used to detect protein levels and confirm protein-protein interaction following immunoprecipitation. Immunofluorescence was used to observe rearrangement of the actin cytoskeleton and cell morphology. Cell migration was assessed by transwell assayResults: Change of cell morphology was concomitant with increased cell migration after treating cells with DHT. Exposure of cells to DHT for one hour was sufficient to induce changes in cell morphology and actin cytoskeleton after 72 hours indicating altered gene expression. A long-term lasting nuclear translocation of AR was observed after a short exposure of cells to DHT. Investigating the expression of 84 EMT-related genes revealed down-expression of ß-catenin, N-cadherin, and TCF-4 and increased expression of Slug, all of which were confirmed at the protein level. Yet, not only early interaction of AR and ß-catenin was observed following AR activation, inhibition of ß-catenin blocked DHT-induced mesenchymal transition and migration. Wnt signaling was found to be partially important in DHT-induced morphological alteration. The mesenchymal transition of cells could be induced by treating cells with an inhibitor of glycogen synthase kinase-3ß, an enzyme that inhibits ß-catenin; this morphological transition could be reversed by antagonizing AR suggesting that AR functions downstream of ß-catenin.Conclusions: These results suggest that MDA-MB-453 cells undergo partial EMT induced by DHT, ß-catenin is critical for this phenotypic change, and AR probably reciprocally mediates the mesenchymal transition of these cells upon activation of GSK-3 ß.

Effect of regular kratom (Mitragyna speciosa Korth.) use on quality of life of people who use kratom.

Background: Kratom (Mitragyna speciosa Korth.) is a traditional folk remedy used in Southeast Asia and is known to have a significant opioid-like effect. However, it is unknown whether kratom consumption can impair quality of life (QoL). This study aimed to examine the QoL of people who use kratom by comparing it with that of healthy non-kratom using controls and to determine the association between patterns of kratom use and QoL among people who use kratom. Methods: 200 respondents (100 subjects who use kratom and 100 healthy controls) were recruited for this cross-sectional study. The World Health Organization Quality of Life-BREF was administered to all the respondents to assess QoL, while the Kratom Dependence Scale (KDS) was used to assess the severity of kratom dependence among the subjects who use kratom. Results: The physical health, psychological, and environment QoL scores of the subjects who use kratom were significantly lower than those of the healthy controls. Multiple linear regression analysis revealed greater KDS score and longer duration of kratom use were significant predictors of physical health QoL, while only greater KDS score significantly predicted psychological and environment QoL scores. Conclusion: Prolonged kratom use and kratom dependence may negatively impact the QoL of people who use kratom, hence kratom addiction has to be treated adequately.

Delicar: A Smart Deep Learning Based Self Driving Product Delivery Car in Perspective of Bangladesh.

The rapid expansion of a country's economy is highly dependent on timely product distribution, which is hampered by terrible traffic congestion. Additional staff are also required to follow the delivery vehicle while it transports documents or records to another destination. This study proposes Delicar, a self-driving product delivery vehicle that can drive the vehicle on the road and report the current geographical location to the authority in real-time through a map. The equipped camera module captures the road image and transfers it to the computer via socket server programming. The raspberry pi sends the camera image and waits for the steering angle value. The image is fed to the pre-trained deep learning model that predicts the steering angle regarding that situation. Then the steering angle value is passed to the raspberry pi that directs the L298 motor driver which direction the wheel should follow. Based upon this direction, L298 decides either forward or left or right or backwards movement. The 3-cell 12V LiPo battery handles the power supply to the raspberry pi and L298 motor driver. A buck converter regulates a 5V 3A power supply to the raspberry pi to be working. Nvidia CNN architecture has been followed, containing nine layers including five convolution layers and three dense layers to develop the steering angle predictive model. Geoip2 (a python library) retrieves the longitude and latitude from the equipped system's IP address to report the live geographical position to the authorities. After that, Folium is used to depict the geographical location. Moreover, the system's infrastructure is far too low-cost and easy to install.

A Patent Review on the Therapeutic Application of Monoclonal Antibodies in COVID-19.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) contains spike proteins that assist the virus in entering host cells. In the absence of a specific intervention, efforts are afoot throughout the world to find an effective treatment for SARS-CoV-2. Through innovative techniques, monoclonal antibodies (MAbs) are being designed and developed to block a particular pathway of SARS-CoV-2 infection. More than 100 patent applications describing the development of MAbs and their application against SARS-CoV-2 have been registered. Most of them target the receptor binding protein so that the interaction between virus and host cell can be prevented. A few monoclonal antibodies are also being patented for the diagnosis of SARS-CoV-2. Some of them, like Regeneron® have already received emergency use authorization. These protein molecules are currently preferred for high-risk patients such as those over 65 years old with compromised immunity and those with metabolic disorders such as obesity. Being highly specific in action, monoclonal antibodies offer one of the most appropriate interventions for both the prevention and treatment of SARS-CoV-2. Technological advancement has helped in producing highly efficacious MAbs. However, these agents are known to induce immunogenic and non-immunogenic reactions. More research and testing are required to establish the suitability of administering MAbs to all patients at risk of developing a severe illness. This patent study is focused on MAbs as a therapeutic option for treating COVID-19, as well as their invention, patenting information, and key characteristics.

The Right to Use Kratom from the Psychiatric and Islamic Perspectives.

This paper aimed to summarize kratom's psychological effects on users and the Islamic views on kratom use. A literature survey of published kratom studies, teachings based on the holy Qur'an, the Sunnah, and views of several Islamic scholars based on qualitative methodology through text analysis was conducted. The results demonstrated that despite its beneficial therapeutic effects, the harm induced by kratom outweighs its benefits. We concluded that kratom use for medicinal purposes is only warranted if useful constituent mitragynine can be extracted and used on its own, and if more rigorous human studies demonstrated good safety profile and efficacy of mitragynine for therapeutic purposes.

Depression and anxiety in the Malaysian urban population and their association with demographic characteristics, quality of life, and the emergence of the COVID-19 pandemic.

The prevalence of depression and anxiety has been shown to be higher in the urban population compared with the rural population. The present study investigated the prevalence of depression symptoms, anxiety symptoms, and depression with comorbid anxiety symptoms and their associated factors in a random sample drawn from several urban communities in Malaysia. This study also determined the association between the emergence of the COVID-19 pandemic and depression symptoms, anxiety symptoms, and depression with comorbid anxiety symptoms. We recruited 326 participants, who were administered a sociodemographic characteristics questionnaire; the 21-item Depression, Anxiety, and Stress Scale (DASS-21) to assess the presence or absence of depression symptoms, anxiety symptoms, and depression with comorbid anxiety symptoms; and the World Health Organization Quality of Life-BREF (WHOQoL-BREF) to assess their QoL. The following prevalence values were obtained among the participants: depression symptoms, 23.9%; anxiety symptoms, 41.7%; and depression with comorbid anxiety symptoms, 19.9%. Those assessed after the declaration of COVID-19 as a global pandemic showed increased odds of depressive symptoms (adjusted OR = 2.99, 95% CI = 1.41-6.35, p = 0.006) and depressive with comorbid anxiety symptoms (adjusted OR = 3.19, 95% CI = 1.37-7.45, p = 0.005), while the presence of comorbid stress increased the odds of depressive symptoms (adjusted OR = 16.00, 95% CI = 7.84-32.63, p < 0.001), anxiety symptoms (adjusted OR = 19.72, 95% CI = 9.75-39.89, p < 0.001), and depressive with comorbid anxiety symptoms (adjusted OR = 40.44, 95% CI = 15.90-102.87, p < 0.001). Higher psychological QoL reduced the odds of depressive symptoms (adjusted OR = 0.83, 95% CI = 0.69-0.99, p = 0.032) and depressive with comorbid anxiety symptoms (adjusted OR = 0.82, 95% CI = 0.68-0.98, p = 0.041), whereas higher physical health QoL (adjusted OR = 0.85, 95% CI = 0.75-0.97, p = 0.021) and social relationship QoL (adjusted OR = 0.70, 95% CI = 0.55-0.90, p = 0.009) reduced the odds of anxiety symptoms. Based on our findings, we recommended several measures to curb psychological complications among the urban population, particularly as the battle to contain COVID-19 is ongoing.
