RESUMO
BACKGROUND: Long-term care facilities (LTC) plays a pivotal role in caring for geriatric population. However, the risk of suicide in long-term care institutions among older individuals is little understood (e.g., nursing homes, assisted living facilities). OBJECTIVE: The purpose of this systematic review is to pool and meta-analyze the data on prevalence of suicidal behaviors in geriatric population residing in long-term care facilities. METHODS: We have conducted the systematic review in accordance with the PRISMA guidelines. The utilized databases are Pubmed, Medline, Google scholar and Scopus. The Meta-analysis was done using OpenMeta [analyst] software. Subgroup analysis was also performed. RESULTS: After running an analysis on pooled data from twenty cross-sectional studies with 3,023,224 participants, the prevalence of suicidal behavior is 6.4% (95% CI = 5.7-7) in LTC. CONCLUSION: This meta-analysis shows pooled prevalence of suicidal behavior among geriatric residents of LTC was found to be moderately high all over the world.
RESUMO
Rapid eye movement sleep behavior disorder (RBD) is linked to other α-synucleinopathies such as Parkinson's disease and Lewy body dementia. It is essential to consider and exclude RBD while studying CSF markers in the latter two to avoid confounding bias and improve test results' specificity.

BACKGROUND: The novel coronavirus disease which is believed to have initially originated in Wuhan city of China at the end of 2019 was declared as pandemic by March 2020 by WHO. This pandemic significantly impacted the mental health of communities around the globe. This project draws data from available research to quantify COVID-19 mental health issues and its prevalence in China during the early period of the COVID-19 crisis. It is believed that this pooling of data will give fair estimate of the effects of the COVID-19 pandemic on mental health. METHODS: We conducted this study in accordance with PRISMA guidelines 2009. The protocol for this review is registered and published in PROSPERO (CRD42020182893). The databases used were Pubmed, Medline, Google scholar and Scopus. The studies were extracted according to pre-defined eligibility criteria and risk of bias assessment was conducted. The Meta-analysis was done using OpenMeta [analyst]. RESULTS: Total of 62382 participants in nineteen studies fulfilled the eligibility criteria. Stress was the most prevalent (48.1%) mental health consequence of Covid-19 pandemic, followed by depression (26.9%) and anxiety (21.8%). After performing subgroup analysis, prevalence of depression and anxiety in both females and frontline health care workers were high as compared to the prevalence in general Chinese population. CONCLUSION: The prevalence of depression and anxiety is moderately high whereas pooled prevalence of stress was found to be very high in Chinese people during this Covid-19 crisis.

OBJECTIVE: To review evidence-based data on spontaneous retrogression of low-grade gliomas with respect to interval till regression, type of glioma and patient outcome. METHODS: The systematic review comprised medical literature in English language published from January 1997 to January 2017 on Scopus, PubMed and Google Scholar databases to establish consensus about the possible mechanism of spontaneous regression, the role of therapeutic intervention and failure of management strategies in low-grade gliomas. Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed during the review. RESULTS: Of the 176 articles identified, 73(41.5%) were shortlisted for detailed assessment. Of them, 10(13.7%) were included; 5(50%) case reports and 5(50%) case series. There were 23 cases of spontaneous regression; 15(65.2%) males and 8(34.7%) females. The interval of regression varied from 3 months to 15.5 years, and the most commonly presenting low-grade glioma type was optic pathway glioma 11(47.4%). CONCLUSIONS: The phenomenon of regression was most evident in optic pathway glioma. Literature suggested that low-grade gliomas should undergo serial imaging before implying any therapeutic intervention. However, the evidencebased proof, large-scale experimental studies and ethical considerations are still required to standardise this strategy.

Robotic surgery has been the forte of minimally invasive stereo-tactic procedures for some decades now. Ongoing advancements and evolutionary developments require substantial evidence to build the consensus about its efficacy in the field of neurosurgery. Main obstacle in obtaining successful results in neurosurgery is fine neural structures and other anatomical limitations. Currently, human rationalisation and robotic precision works in symbiosis to provide improved results. We reviewed the current data about recent interventions. Robots are capable of providing virtual data, superior spatial resolution and geometric accuracy, superior dexterity, faster manoeuvring and non-fatigability with steady motion. Robotic surgery also allows simulation of virtual procedures which turn out to be of great succour for young apprentice surgeons to practise their surgical skills in a safe environment. It also allows senior professionals to rehearse difficult cases before involving into considerable risky procedures.

Aim: Parkinson's disease (PD) is a progressive neurological disorder that predominately affects dopaminergic neurons. We believe that this pooling of data will help to better understand the prodromal nature of depression in PD. Materials & methods: We conducted this study in accordance with PRISMA guidelines 2020. Fifteen eligible articles were shortlisted for final analysis. Risk of bias assessment was also conducted Results: The random-effect model revealed that the risk of subsequent PD in patients with prodromal depression was twice as likely (odds ratio, 2.04; 95% CI, 1.02-4.08) as compared with a healthy population. Conclusion: Our meta-analysis concluded that the subsequent risk of PD is significantly higher in patients with depression as compared with healthy individuals.
Parkinson's disease (PD) is a nervous system disease that predominantly affects neurons of the brain that controls voluntary movement and behavioral processes such as mood, reward, addiction and stress. There is a wide spectrum of problems that can present in patients with PD, however, there are few that can precede the beginning of the illness. Previous studies have evaluated the relation of psychiatric symptoms with PD. However, many aspects need to be studied to understand this relationship. The main emphasis of this systemic review is to establish the association of prodromal depression before the development of PD. Our study showed that there is a strong association between depression and PD and suggests an increased risk of developing PD in formerly depressed patients. Though, it is still unclear if depression is either an early prodromal symptom of PD or a causative risk factor for PD and warrants further studies to determine the causality relationship between the two.

Purpose of Review: With other life-altering changes, Covid-19 pandemic has brought a mental health crisis upon the global community. Untreated psychological disturbances can lead to tragic outcomes such as suicide. Currently, the most feasible way to know the true burden of Covid-related suicides is through media reports. However, the standards of media-reported suicide cases and their compliance to WHO checklist of suicide reporting in Pakistan, India, and Bangladesh are concerning. The question that arises here is if we can truly rely on the media reporting system of these countries to establish exposure-causality relationship. We've attempted to gather the evidence of reporting sources of Covid-related suicide cases in Pakistan, India, and Bangladesh. We've conducted a systematic review in accordance with the PRISMA guidelines to identify the media-reported cases of COVID-related suicides. Recent Findings: After compilation of the results, it was observed that most of the reported cases were from India (74.2%) whereas males died of suicide more often than females. When risk of bias was assessed using Pierson's method, it was observed that 70% of the studies had high risk of bias. Summary: We've attempted to gather the evidence of reporting sources of Covid-related suicide cases in Pakistan, India, and Bangladesh and found that nearly all media reports hadn't followed the WHO reporting guidelines for suicide cases. This could lead to a false sense of panic among the general population.
RESUMO
INTRODUCTION: Addiction refers to the irresistible urge to engage in certain actions or dependence on a particular substance despite knowing negative consequences. The current study evaluated the severity of Smartphone addiction and the factors associated with cell phone-like activity. MATERIALS AND METHODS: This cross-sectional study was conducted from July to August 2019 among medical and dental students in Karachi, Pakistan. A pretested self-administered questionnaire was used among 400 students. The mobile phone addiction was assessed using a 20-item, Mobile Phone Addiction Scale. A two-stage cluster analysis was used to assess mobile phone addiction-like behaviours. Chi-square test was used to find associations between categorical variables. Kolmogorov-Smirnov to test normality of data were also used. A P < 0.05 was considered to be statistically significant for all tests. RESULTS: Out of the total 400 students, the majority 316 (79%) comprise female students. The mean age was 20.54 ± 1.59 years. In 184 (48%) students, there was evidence of mobile phone addiction-like behavior. The prevalence was higher in female than male students and among older compared to adolescent students; the differences were statistically nonsignificant. A higher median score ≥ of 4 is found in questions related to components reflected intense desire, impaired control, and tolerance and harmful mobile use. CONCLUSION: This study highlights that a large number of students are addicted to their smartphones. Smartphone addiction continues to be the most problematic addiction aided by the presence of intense desire, impaired control tolerance, and harmful mobile use. The phenomenon must be fully understood to draw deeper and richer inferences about the origins of this addictive behavior, which is becoming more prevalent in our Pakistani society on a daily basis.
RESUMO
Objective Giant cell arthritis (GCA) is a type of vasculitis which is more common in female gender and is closely associated with Polymyalgia rheumatic. One of its important complication include visual impairment. The burden of disease is expected to be very high by 2050 and there is a need to compile the data on most influential studies on GCA to define future strategy to deal with this dangerous disease. Bibliometrics is a statistical analysis of published literature that reflects the value and impact of a particular publication within the specific field. Aim of our study is identify the most significant contributors and their quality of contribution in the field. Method We conducted this analysis utilizing SCOPUS database using different related MeSH terms. After a detailed screening, the list of top-50 articles were presented in the results in descending order of their ranks on the basis of their total number of citation. Most of our data comprises of publications from 1971-2012. Result The top-50 most cited articles on GCA were published between 1971 and 2012 with the median number of citations 274 ranging from 598-187. Annals of Internal Medicine was the top ranked journal with 13 publications from the list. The highly ranked author based on the number of publications was Hunder GG (20 publications) with h-index of 40, retaining affiliation with Mayo Clinic, Rochester, United States. Mayo Clinic was the most frequently mentioned institute among the affiliations. The United States was found to be the most productive country rendering most of the articles (64%). Conclusion Our bibliometric analysis on Giant cell arteritis identifies the information which may direct future research contributions, identify field experts, guide researchers to fill knowledge gaps, and assist in research fund allocation.
RESUMO
BACKGROUND: Citation count can be used as a key tool to assess the quality of the published literature and because of its immense advantages it is now widely used in ranking the articles on specific topics. OBJECTIVE/HYPOTHESIS: To extract and assess the top cited work on repetitive transcranial magnetic stimulation (rTMS) for depression treatment. METHODS: Scopus Library Database was searched and two independent authors produced a list of 50 most cited articles on repetitive transcranial magnetic stimulation (rTMS) for treatment of depression. All the relevant articles having key-terms within their titles, abstract and keywords were included in our search. Our list was categorized into two categories, "mixed" and "focused". RESULTS: The articles in the produced list of top 50 most cited articles on rTMS for treatment of depression belong to the time period 1993-2012 with total citation count 12078. George MS was prominent in the list. 'Biological Psychiatry' published most number of articles (n = 13) among the list. Articles were categorized on the basis of primary population and intervention into 'Focused' and 'Mixed' categories. LIMITATIONS: Articles that were published before 1993 and after 2012 on rTMS for depression couldn't made it to the final list of top-50 most cited article. CONCLUSION: We attempted to conduct a topic-specific citation analysis considering the paucity of specified bibliometrics in medical literature. Our research provides an insight on emerging trends in rTMS for depression and highlights the characteristics, quality and dynamics of frequently cited articles in the field.
RESUMO
Multiple sclerosis (MS) is a chronic neuro-inflammatory, immune-mediated disorder of the central nervous system; however, less is known about its cause. It causes neurological disability in young adults, more commonly in women. Several risk factors including environmental, genetics, and infections have been identified, which contribute to the abnormal immune response. Viruses belonging to the Herpes family have been indicated as a potential risk for MS; their biological mechanisms are not known but several possibilities have been discussed. Epstein-Barr virus (EBV) is the leading and most common virus associated with MS. It is a potential oncogenic virus that hosts the B lymphocytes and has been associated with numerous cancers such as Burkitt's lymphoma, Hodgkin's lymphoma, and nasopharyngeal carcinoma. The risk of MS is low in patients who are EBV negative but increases by several folds in individuals who have a history of infectious mononucleosis (IM). Several ecological studies, co-occurring pathologies, and experimental laboratory-based research provide evidence to support the relationship between EBV and MS.
RESUMO
BACKGROUND: Anger is defined as an emotional state that involves displeasure and consists of subjective feelings that vary in intensity, from mild irritation or annoyance to intense fury and rage. Anger is dangerous because it affects the health of the individual. It also affects relationships between fellow physicians and nurses and can ultimately compromise patient care. Medical school is perceived as stressful and a number of studies have proved the high prevalence of anxiety, stress, and depression in medical students. However, no significant studies have been performed to assess the frequency of anger in medical students. The purpose of our study is to find out whether anger is prevalent among medical students and its effect on different aspects of student's lives. METHODS: A cross-sectional survey was conducted on the students from all five years of Liaquat National Medical College. Sampling technique used was nonprobability purposive sampling. A self-administered questionnaire was filled by medical students. Data were recorded and analyzed using the IBM statistics SPSS software. RESULTS: A total of 205 students participated in the survey. Using the questionnaire, it was found that the highest frequency of anger was found in first-year students (97.5%), followed by the fourth year (97.4%), final year (97.2%), third year (95.7%), and second year (91.9%). All five years identified stress as a major predictor of anger. Anger had the greatest effect on decision making, especially in final year medical students. CONCLUSION: Authors concluded a high frequency of anger in medical students. Increased stress has negative impacts on the mental health and coping strategies of students which greatly affect their decision-making power.
RESUMO
Background Aneurysmal subarachnoid hemorrhage is a frequently devastating condition with a reported incidence of between 10 and 15 people per 100,000 in the United States. Currently, according to the best of our knowledge, there are not enough meta-analyses available in the medical literature of the last five years which compare the risks and benefits of endovascular coiling with neurosurgical clipping. Methods Twenty-two studies were selected out of the short-listed studies. The studies were selected on the basis of relevance to the topic, sample size, sampling technique, and randomization. Data were analyzed on Revman software. Results Mortality was found to be significantly higher in the endovascular coiling group (odds ratio (OR): 1.17; confidence interval (CI): 95%, 1.04, 1.32). Re-bleeding was significantly higher in endovascular coiling (OR: 2.87; CI: 95%, 1.67, 4.93). Post-procedure complications were significantly higher in neurosurgical clipping compared to endovascular coiling (OR: 0.36; CI: 95%, 0.24, 0.56). Neurosurgical clipping was a 3.82 times better surgical technique in terms of re-bleeding (Z = 3.82, p = 0.0001). Neurosurgical clipping is a better technique requiring fewer re-treatments compared to endovascular coiling (OR: 4.64; CI: 95%, 2.31, 9.29). Endovascular coiling was found to be a better technique as it requires less rehabilitation compared to neurosurgical clipping (OR: 0.75; CI: 95%, 0.64,0.87). Conclusion Neurosurgical clipping provides better results in terms of mortality, re-bleeding, and re-treatments. Endovascular coiling is a better surgical technique in terms of post-operative complications, favorable outcomes, and rehabilitation.
RESUMO
Glioblastoma multiforme (GBM) has been the topic of immense research in recent years. The suitable therapeutic approach towards this wild-type p53 tumor has been the topic of ongoing discussion for some decades now. There has been a substantial debate about the role of mouse double minute-2 (MDM-2) antagonists in the treatment of GBM recently. We have reviewed the current data in our study to establish the consensus about recent interventions. Our review of the literature suggests that MDM-2 antagonists are currently a more suitable approach with improved efficacy, and it might be utilized in the future for significant results. Newer analogs of MDM-2 antagonists with better pharmacokinetics profiles and the least drug-drug interactions were also discussed in our research. It was concluded that MDM-2 antagonists are improved therapy against GBM but evidential proof with more experimental studies is needed to standardize this therapy in near future.
RESUMO
Background: Cardiac muscle possesses a limited capacity to regenerate its tissue on its own. It is less likely to reverse the altered cardiac functioning to its normal physiological state after a major myocardial infarction. Stem cell transplantation provided a unique therapeutic approach in managing such injuries. There has been a substantial debate about the complexity, scope and medical application of stem cell transplantation in past few years. Materials and Methods: An extensive review of medical literature was conducted to establish the consensus about the possible mechanism of cell renewal, associated complications and risks of failure of this technique. Twenty cases of mammalian animals and twenty-four cases of stem cell transplantation in human subjects were reviewed. Results: Most common associated complication was re-stenosis of coronary artery. Few clinical trials reported the failure in improving cardiac functioning. The success rate of stem cell transplantation was remarkable in the literature related to experimental animal subjects. Conclusion: It was concluded that renewal of the cardiac cell is a result of induction of angiogenesis and prolonged cell survival. This topic still requires an immense amount of research to fill the gap in adequate knowledge.
RESUMO
The first line of treatment for lumbar spinal stenosis (with or without lumbar degenerative spondylolisthesis) involves conservative options such as anti-inflammatory drugs and analgesics. Approximately, 10%-15% of patients require surgery. Surgical treatment aims to decompress the spinal canal and dural sac from degenerative bony and ligamentous overgrowth. Different studies have given conflicting results. The aim of our study is to clear the confusion by comparing two surgical techniques. This meta-analysis was conducted in accordance with the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. A literature search was conducted of the Ovid Embase, Scopus, Pubmed, Ovid Medline, Google Scholar, and Cochrane library databases. A quality and risk of bias assessment was also done. The analysis was done using Revman software (The Nordic Cochrane Centre, The Cochrane Collaboration, 2014, Copenhagen, Denmark). A total of 76 studies were extracted from the literature search and 29 studies with relevant information were shortlisted. Nine studies were included in the meta-analysis after a quality assessment and eligibility. Fusion with decompression surgery was found to be a better technique when compared to decompression alone for spinal stenosis in terms of the Oswestry Disability index and the visual analog pain scale for back and leg pain. On the basis of the meta-analysis of the recent medical literature, the authors concluded that decompression with fusion is a 3.5-times better surgical technique than decompression alone for spinal stenosis.
RESUMO
Glioblastoma, also known as glioblastoma multiforme (GBM), is the most common primary brain tumor. Extensive research has been carried out to discover the factors associated with the course and progression of GBM. CD133 is a glycoprotein antigen found in normal and malignant tissues. CD133 has been recognized as a marker for the growth of cancer cells. The association between this tissue marker and GBM is being investigated. The aim of this review was to evaluate the role of CD133 as a tumor marker for the prognosis of GBM.
RESUMO
Third ventricle tumors are uncommon and account for 0.6 - 0.9% of all the brain tumors. Tumors of the third ventricle are classified into primary tumors, such as colloid cysts, choroid plexus papillomas, and ependymomas, or secondary tumors, such as craniopharyngiomas, optic nerve gliomas, pineal tumors, and meningiomas. Third ventricular tumors are uncommon, and their treatment involves significant morbidity and mortality. The colloid cyst has a better surgical outcome and many approaches are available to achieve a complete cure. Choroid plexus papilloma is also a common tumor documented with its treatment majorly based on surgical resection. In addition to multiple treatment options for craniopharyngiomas, surgery is the most preferred treatment option. Ependymomas also have few treatment options, with surgical resection adopted as the first line of treatment.
RESUMO
BACKGROUND: Intracranial arteriovenous malformations (AVMs) consist of an abnormal nidus of blood vessels that shunt blood directly from an artery to a vein and thereby bypass an intervening capillary bed. AVMs may be found as an incidental finding. They may be associated with intracranial haemorrhage, seizures, headaches or neurological deficits. There are different treatment options for AVM. These include observation, microsurgery, Stereotactic radio surgery (SRS), endovascular embolization and intensity modulated radiotherapy (IMRT). METHODS: Data was collected using searching engines like Pubmed, Google scholar, Embase, Cinahl and Medline. MeSH and Non-MeSH terms were used like Arterio-venous malformations, microsurgery, endovascular embolization. RESULTS: Multiple interventional radiosurgical techniques have been introduced in recent years. The most effective and least risk-associated methods are Stereotactic radiosurgery, Microsurgery, Embolization and Intensity modulated radiotherapy (IMRT). However, the outcome of such treatment modalities depends upon Site of malformation, grade of AVM, patient's age/gender, dose and volume of radiosurgery. Digital substraction angiography (DSA) and MR angiography (MRA) are most suitable methods for the follow-up of AVMs. CONCLUSIONS: Stereotactic radiosurgery is the most suitable technique for AVMs considering the good prognosis and the risks associated with this procedure. However, large AVMs require multidisciplinary approach for better results.
