Objectives The objectives of this study were to investigate the incidence of demyelinating disease (DD) among SpA patients and to identify risk factors that predict DD in this patient population. Methods Axial SpA (axSpA) and PsA patients were identified from a longitudinal cohort database. Each group was analysed according to the presence or absence of DD. Incidence rates (IRs) of DD were obtained, with competing risk analysis. Cox regression analysis (with Fine and Gray's method) was used to evaluate predictors of DD development. Results Among 2260 patients with follow-up data, we identified 18 DD events, corresponding to an average IR of 31 per 100 000 persons per year for SpA. The IR of DD at 20 years was higher in axSpA than in PsA (1.30% vs 0.13%, P  = 0.01). The risk factors retained in the best predictive model for DD development included ever- (vs never-) smoking [hazard ratio (HR) 2.918, 95% CI 1.037–8.214, P  = 0.0426], axSpA (vs PsA) (HR 8.790, 95% CI 1.242–62.182, P  = 0.0294) and presence (vs absence) of IBD (HR 5.698, 95% CI 2.083–15.589, P  = 0.0007). History of TNF-α inhibitor therapy was not a predictor of DD. Conclusion The overall incidence of DD in this SpA cohort was low. Incident DD was higher in axSpA than in PsA. A diagnosis of axSpA, the presence of IBD, and ever-smoking predicted the development of DD. History of TNF-α inhibitor use was not found to be a predictor of DD in this cohort.

Background: Performing routine brain magnetic resonance imaging (MRI) is widely accepted as the standard of care for disease monitoring in multiple sclerosis (MS), but the utility of performing routine spinal cord (SC) MRI for this purpose is still debatable. Objective: This study aimed to measure the frequency of new isolated cervical spinal cord lesions (CSLs) in people with MS (pwMS) undergoing routine brain and cervical SC-MRI for disease monitoring and determine the factors associated with the development of new CSLs and their prognostic value. Methods: We retrospectively identified 1576 pwMS who underwent follow-up 3T brain and cervical SC-MRI over a 9-month period. MRI was reviewed for the presence of new brain lesions (BLs) and CSLs. Clinical records were reviewed for interval relapses between sequential scans and subsequent clinical relapse and disability worsening after the follow-up MRI. Results: In 1285 pwMS (median interval: 13–14 months) who were clinically stable with respect to relapses, 73 (5.7%) had new CSLs, of which 49 (3.8%) had concomitant new BLs and 24 (1.9%) had new isolated CSLs only. New asymptomatic CSLs were associated with ⩾ 3 prior relapses (p = 0.04), no disease-modifying therapy (DMT) use (p = 0.048), and ⩾ 3 new BLs (p < 0.001); ⩾ 3 new BLs (OR: 7.11, 95% CI: 4.3–11.7, p < 0.001) remained independently associated with new CSLs on multivariable analysis. Having new asymptomatic CSLs was not independently associated with subsequent relapse or disability worsening after the follow-up MRI (median follow-up time of 26 months). Conclusion: Routine brain and cervical SC-MRI detected new isolated CSLs in only < 2% of clinically stable pwMS. Developing new asymptomatic CSLs was associated with concomitant new BLs and did not confer an independent increased risk of relapse or disability worsening. Performing SC-MRI may not be warranted for routine monitoring in most pwMS, and performing only brain MRI may be sufficient to capture the vast majority of clinically silent disease activity.

Background: Patients with coronavirus disease 2019 (COVID-19) and coronary artery disease (CAD) or heart failure (HF) are more likely to have poor outcomes. This study aimed to determine the characteristics and outcomes of COVID-19 patients with CAD/HF across various institutions in the Philippines. Methods: We utilized the data from the Philippine CORONA Study and compared the outcomes of admitted COVID-19 patients with CAD/HF versus those without. The Student's t test, Mann-Whitney U test, binary logistic regression and multivariate regression analysis were utilized. Odds ratios (OR) and Kaplan-Meier curves were generated. Results: We included a total of 512 patients with COVID-19 had CAD/HF and 10,369 were without. CAD/HF was significantly associated with COVID severity, all-cause mortality, death from cardiac causes, respiratory failure, and prolonged hospitalization. After adjusting for confounders, the presence of CAD/HF was still associated with death from a cardiac cause (OR 2.22, 95% CI 1.49–3.3, p < 0.01). Conclusions: The presence of CAD or HF was significantly associated with severity of COVID disease, all-cause mortality, death from cardiac causes, respiratory failure, and prolonged hospitalization.

Background: The global pandemic caused by the coronavirus disease 2019 (COVID-19) resulted in many deaths from fulminant respiratory failure. Chronic obstructive pulmonary disease (COPD) is the leading cause of morbidity and mortality worldwide. There has been great concern regarding the impact of COPD on the COVID-19 illness. Methods: Data from the Philippine CORONA study were analyzed to determine the association of COPD and COVID-19 in terms of mortality, disease severity, respiratory failure, mechanical ventilation, and lengths of stay in the intensive care unit (ICU) and hospital. Results: A total of 10,881 patients were included in this study, and 156 (1.4%) patients had been diagnosed with COPD. A majority of COVID-19 patients with COPD had other existing comorbidities: hypertension, diabetes mellitus, chronic cardiac disease, and chronic kidney disease. COPD patients were 2.0× more likely to present with severe to critical COVID-19 disease. COVID-19 patients with COPD in our study have a 1.7× increased mortality, 1.6× increased respiratory failure, and 2.0× increased risk for ICU admission. Smokers with COVID-19 were 1.8× more likely to present with more severe disease and have a 1.9× increased mortality. Conclusion: Our study supports the growing evidence that COPD among COVID-19 patients is a risk factor for higher mortality, more severe form of COVID-19, higher ICU admission, and higher respiratory failure needing ventilatory support.

Background: We aimed to determine the effects and tolerability of repetitive transcranial magnetic stimulation (rTMS) on apathy in patients with neurodegenerative conditions, mild cognitive impairment (MCI), stroke, and traumatic brain injury (TBI) via systematic review. Methods: We conducted a systematic search in major electronic health databases, including PubMed, Scopus, and PsycINFO, covering the period from inception to June 2023. Comparative clinical trials and cohort studies, and studies with before-after designs were considered for inclusion. We used the Cochrane Risk of Bias and the National Institutes of Health (NIH) tools to assess methodological quality. Results: Out of 258 records identified, 14 studies met our eligibility criteria (11 randomized controlled trials (RCT) and 3 studies utilized before-and-after designs) with a total of 418 patients (overall female-to-male ratio 1:1.17) included in the review. The overall methodological quality of the included studies was assessed to be fair to good. The stimulation parameters used varied considerably across the studies. The summary findings of our review indicate the following observations on the effects of rTMS on apathy: (1) the results of all included studies in Alzheimer’s disease investigating the effects of rTMS on apathy have consistently shown a positive impact on apathy; (2) the majority of studies conducted in Parkinson’s disease have not found statistically significant results; (3) a single study (RCT) on patients with primary progressive aphasia demonstrated significant beneficial effects of rTMS on apathy; (4) the trials conducted on individuals with MCI yielded varying conclusions; (5) one study (RCT) in chronic stroke suggested that rTMS might have the potential to improve apathy; (6) one study conducted on individuals with mild TBI did not find a significant favorable association on apathy; and (7) the use of different rTMS protocols on the populations described is generally safe. Conclusion: The feasibility of utilizing rTMS as a treatment for apathy has been suggested in this review. Overall, limited evidence suggests that rTMS intervention may have the potential to modify apathy among patients with AD, PPA, MCI and chronic stroke, but less so in PD and mild TBI. These findings require confirmation by larger, well-designed clinical trials. [ABSTRACT FROM AUTHOR]

Objective: To describe the association between hypertension and clinical outcomes in a cohort of patients with coronavirus disease 2019 (COVID-19). Design: Retrospective cohort study. Setting: Thirty-seven (37) hospitals in the Philippines. Patients: 10,881 patients admitted for COVID-19 from February to December 2020. Measurements and main results: Among the 10,881 patients included in the Philippine CORONA Study, 3647 (33.5%) had hypertension. On regression analysis adjusted for confounders (age group, sex, smoking history, diabetes, chronic cardiac disease, chronic kidney disease, chronic respiratory disease, chronic neurologic disease, chronic liver disease, HIV/AIDS, and malignancy), patients with hypertension had significantly greater odds of in-hospital mortality (OR 1.33, 95% CI 1.17–1.52), respiratory failure (OR 1.99, 95% CI 1.75–2.28), ICU admission (OR 2.16, 95% CI 1.90–2.45) and severe/critical disease (OR 1.57, 95% CI 1.41–1.75), compared to patients without hypertension. The time-to-event analysis with confounder adjustment also showed that hypertension was significantly associated with shorter time-to-event outcomes of in-hospital mortality (HR 1.13, 95% CI 1.01–1.26), respiratory failure (HR 1.86, 95% CI 1.65–2.10), and ICU admission (HR 1.99, 95% CI 1.76–2.23). Conclusions: Our analysis of nationwide data confirmed previous findings that hypertension is an independent risk factor for worse clinical outcomes among patients hospitalized for COVID-19, with increased odds of in-hospital mortality, respiratory failure, ICU admission, and severe/critical COVID-19. More specific studies should be done to elucidate the impact of hypertension characteristics, such as chronicity, severity, drug therapy, and level of control on these clinical outcomes.

Objective: Our study determined the association of pregnancy with various clinical outcomes among women with COVID-19 infection. Methods: We conducted a retrospective, cohort, subgroup analysis of the Philippine CORONA Study datasets comparing the clinical/neurological manifestations and outcomes of pregnant and nonpregnant women admitted in 37 Philippine hospitals for COVID-19 infection. Results: We included 2448 women in the analyses (322 pregnant and 2.126 nonpregnant). Logistic regression models showed that crude odds ratio (OR) for mortality (OR 0.26 [95% CI 0.11, 0.66]), respiratory failure [OR 0.37 [95% CI 0.17, 0.80]), need for intensive care (OR 0.39 [95% CI 0.19, 0.80]), and prolonged length of hospital stay (OR 1.73 [95% CI 1.36, 2.19]) among pregnant women were significant. After adjusting for age, disease severity, and new-onset neurological symptoms, only the length of hospital stay remained significant (adjusted OR 1.99 [95% CI 1.56,2.54]). Cox regression models revealed that the unadjusted hazard ratio (HR) for mortality (HR 0.22 [95% CI 0.09, 0.55]) among pregnant women was statistically significant; however, after adjustment, the HR for mortality became nonsignificant. Conclusion: We did not find a significantly increased risk of mortality, respiratory failure, and need for ICU admission in pregnant women compared with nonpregnant women with COVID-19. However, the likelihood of hospital confinement beyond 14 days was twice more likely among pregnant women than nonpregnant women with COVID-19. [ABSTRACT FROM AUTHOR]

Background: A dengue vaccine, dengvaxia, was licensed for the first time in 2015. It was approved for use in 11 countries where dengue infection is endemic, including the Philippines. In November 2017, controversy arose in the Philippines regarding the dengvaxia vaccine. We hypothesized that the dengvaxia controversy might be correlated with immunization coverage in the Philippines. Methods: We performed an analytical and infodemiological study on web‐based interest in dengvaxia, both globally and in 18 dengue endemic countries, from 2015 to 2020 using Google Trends™. Comparisons were made with search trends for the components of the National Immunization Program (NIP) and vaccine coverage by computing the Pearson product–moment correlation coefficient (r) between each variable. Results: Among the 18 countries included, the Philippines had the highest search volume index for dengvaxia, with peaks in searches coinciding with that of worldwide search trends. There was no correlation between the relative search volume for dengvaxia with that of vaccines included in the NIP in the Philippines from 2015 to 2020. There was no significant correlation between web‐based interest in dengvaxia and the estimated immunization coverage from 2015 to 2019. Conclusion: There was no significant correlation between web‐based interest in dengvaxia, the vaccines in the NIP, and national immunization coverage. [ABSTRACT FROM AUTHOR]

Introduction: The Philippine CORONA Study was a multicenter, retrospective, cohort study of 10,881 coronavirus disease 2019 (COVID-19) admissions between February and December 2020. Methods: Subgroup analysis was done on clinical outcomes of mortality, respiratory failure, duration of ventilator dependence, intensive care unit (ICU) admission, length of ICU stay, and length of hospital stay among older persons and persons with dementia. Results: The adjusted hazard ratios for mortality among the mild and severe cases were significantly higher by 3.93, 95% CI [2.81, 5.50] and by 1.81, 95% CI [1.43, 2.93], respectively, in older persons compared to younger adults. The adjusted hazard ratios for respiratory failure in older persons were increased by 2.65, 95% CI [1.92, 3.68] and by 1.27, 95% CI [1.01, 1.59] among the mild and severe cases, respectively. The adjusted hazard ratio for ICU admission in older persons was higher by 1.95, 95% CI [1.47, 2.59] among the mild cases. The adjusted hazard ratios for mortality and ICU admission in persons with dementia were higher by 7.25, 95% CI [2.67, 19.68] and by 4.37, 95% CI [1.08, 17.63], respectively, compared to those without dementia. Conclusion: Older age and dementia significantly increased the risk of mortality, respiratory failure, and ICU admission among COVID-19 patients. [ABSTRACT FROM AUTHOR]

Little is known about the survivorship of glioblastoma (GBM) patients in low- and middle-income countries (LMICs). We hypothesize that this would be lower than published figures for high-income countries due to cancer health disparities. We performed a systematic review and meta-analysis to estimate the median overall survival (OS) of GBM in LMICs and determine factors affecting OS. A systematic review of 12 electronic databases was conducted according to PRISMA guidelines to identify studies of newly diagnosed adult GBM patients done in countries classified as LMIC by the World Bank (WB) from inception to December 2020. Random effects meta-analysis of collected median overall survival data was done. Subgroup analysis and meta-regression were done to determine if WB income classification (WBIC), start year of recruitment (pre- or post-popularization of the standard Stupp protocol), and treatment modality affected OS. The 24 articles (n = 2,552) that met the inclusion criteria were from 8 low-middle income and upper-middle income countries, with 0 articles from low-income countries. Random effects analysis of 24 studies showed a pooled median OS of 14.17 months (95% CI 12.90–15.43, I2 = 79). Subgroup analysis showed a significant difference (p < 0.05) in the pooled median OS of studies predating Stupp protocol (12.54 mo, 95% CI 11.13–13.96, I2 = 80%; n = 1027) and studies postdating Stupp protocol (15.64 mo, 95% CI 13.58–17.69, I2 = 77; n = 1412). Subgroup analysis of WBIC and treatment modalities did not show significant differences. Published data on the survivorship of GBM patients in LMICs is sparse, highlighting the need for good quality pragmatic studies from LMICs. The limited evidence suggests improving survivorship after introduction of the Stupp protocol. [ABSTRACT FROM AUTHOR]

Background: The conduct of patient consults greatly changed during the time of the COVID-19 pandemic. There was a decrease in face-to-face patient consults and enhanced utilization of virtual consults. Infodemiological studies, using Google Trends, focus on internet search trends that may reflect public interest and awareness in diseases and as a proxy of public health risk perception. Objectives: We aimed to investigate the online behavior of internet users on teleneurology, telehealth, and telemedicine during the time of the pandemic, as reflected in search volume indices (SVI) projected in Google Trends. Methods: We used the data from Google Trends to quantify the interest of internet users in teleneurology, telehealth, and telemedicine. These keywords were entered in Google Trends as search terms. Data included were searches conducted from 2016 to 2020 to depict the transition into the pandemic. Results: The SVI of teleneurology was unchanged during the 5-year period search relative to the SVIs of telehealth and telemedicine. Contrary to the noted worldwide increase in the SVI of telehealth and telemedicine during the year of pandemic, teleneurology's SVI remained stable despite the increase of its utilization. Focusing on teleneurology, the highest SVI was observed in 2018. Conclusion: There was an increase in the SVI of telehealth and telemedicine, possibly implying an increase in the general awareness of these virtual methods of health care, as catalyzed by the pandemic. However, the stable SVI of teleneurology may signify that the public awareness regarding it remained unchanged despite the increase in application in clinics and hospitals. [ABSTRACT FROM AUTHOR]

Background: Searching the internet for information on common neurologic symptoms and diseases has been increasing in recent times. It is postulated that online search volume data could be utilized to gauge public awareness and real-world epidemiological data regarding brain tumors. Objectives: The goal of this study was to describe the pattern of online search queries of keywords related to neoplasms of the central nervous system (CNS). Methods: Using Google Trends, search activity from January 2004 – January 2021 was quantified using relative search volume (RSV). The average RSV for the first 3 years was compared with the final 3 years to account for percent change. Wikipedia article views from July 2007 – January 2021 were generated using Pageviews. Peaks in RSV and page views were then matched for related news. Results: "Brain tumor", "brain cancer", "glioblastoma", and "glioma" had the highest search volume. RSV from Google Trends and views of Wikipedia pages reflected comparable data in terms of known prevalence rankings of tumor subtypes. There were no observable trends that could correlate to the rising numbers of brain tumor cases worldwide. However, headlines of personalities being diagnosed with glioblastomas were mostly responsible for temporary increases in public interest. Conclusions: Transient rises in online search volume mirror public awareness of more aggressive CNS neoplasms that have a high burden of disease. Worldwide interest in brain tumors may not necessarily correspond to clinical occurrence, but may signify an unmet gap in providing accurate online information to neuro-oncologic patients.

Background: A study conducted in China on patients with coronavirus disease 2019 (COVID-19) showed that cancer conferred a five times increased risk for needing intensive care admission and mortality; No data has yet been collected and published from the Philippines. Thus, the investigators conducted this substudy to determine the association of having a history of cancer with clinical outcomes among patients included in the Philippine CORONA Study. Methodology: Multi-center, retrospective cohort design Results: A total of 244 patients had a history of cancer, out of 10,881 COVID-19 hospital admissions. After adjusting for different confounding variables of interest, having cancer was significantly associated with a 75% increased odds of having severe/critical COVID-19 at nadir (CI 95% 1.32, 2.33; p < 0.001). After adjusting for different confounding variables of interest, having cancer was significantly associated with the following time-to-event outcomes: 72% increase in hazard of in-hospital mortality (CI 95% 1.37, 2.16; p < 0.001), 65% increase in hazard of respiratory failure (CI 95% 1.31, 2.08; p < 0.001), and 57% increase in hazard of being admitted to ICU (CI 95% 1.24, 1.97; p < 0.001). Conclusion: A history of cancer conferred poorer clinical outcomes on adult, hospitalized COVID-19 patients. [ABSTRACT FROM AUTHOR]

Background: Neurology residents are particularly vulnerable to burnout because of the novel logistical and clinical challenges brought about by the coronavirus disease 2019 (COVID-19) pandemic. Despite its implications, knowledge on burnout and its predictors among neurology residents is lacking. This study aimed to determine the prevalence of burnout among neurology residents during the pandemic, to compare burnout subscale scores and sociodemographic and work characteristics, and to explore residents' perceptions on how to address burnout. Methods: We conducted a cross-sectional survey among all 120 residents from the nine institutions in the Philippines offering neurology residency programs from March to August 2020. We obtained sociodemographic and work characteristics using questionnaire. We measured burnout using the Maslach Burnout Inventory. We performed an inductive thematic analysis to analyze perceptions on how to reduce burnout. Results: The response rate was 71.67% (86/120). The mean age was 30.1 ± 3.1 years. Using predefined subscale critical boundaries, the prevalence of burnout was 94% (95% CI 89, 99). The lack of compensation and number of on-duty days influenced emotional exhaustion scores. The number of on-duty days influenced depersonalization scores. Thematic analysis revealed five themes: increasing manpower; self-care; reducing clerical tasks; improving work environment; and adequate compensation. Conclusions: The prevalence of burnout among neurology residents during the COVID-19 pandemic was alarmingly high. Reforms in hiring policies, work-hour management, manpower organization, work environment, and logistics may be considered. [ABSTRACT FROM AUTHOR]

Background: Amyotrophic lateral sclerosis (ALS) is a fatal and incurable neurodegenerative disease. There is still no established cost-effective treatment that can improve functional status and survival of ALS patients. Perampanel, by inhibiting neuronal calcium ion influx and preventing dyslocalization of nuclear proteins, has the potential to ameliorate ALS neurodegeneration.Objectives: This study aims to determine the efficacy and safety of perampanel among ALS patients in terms of improvement in functional status using a review of relevant studies.Methods: MedLine, Cochrane Central Register for Controlled Trials, Scopus, Embase, Literatura Latino-Americana e do Caribe em Ciências da Saúde, ClinicalTrials.gov website, and HERDIN databases were searched from inception to August 2021 for relevant studies.Results: The search yielded 132 articles; 3 studies were included in the analysis. Pooled evidence shows that perampanel compared to placebo significantly improves cortical motor hyperexcitability but not the ALS functional rating scale-revised score. Perampanel is associated with adverse events such as aggression, somnolence, anger, and dysarthria.Conclusion: There is no sufficient evidence to support the role of perampanel in improving functional status of ALS patients. Although it can ameliorate motor cortical hyperexcitability, its clinical benefit has not yet been elucidated. Perampanel is not well tolerated among ALS patients as it is associated with adverse events such as aggression, somnolence, anger, and dysarthria. Further studies investigating the role of perampanel early in the ALS disease course, excluding ALS patients with frontotemporal lobe degeneration features and C9ORF72 repeat expansion, and using gradual drug titration schedule are needed to evaluate the potential benefit of perampanel in ALS.

Background and objectives: The practice of teleneurology provided an accessible and safe method of consultation during the COVID-19 pandemic. We aimed to describe the practice of teleneurology among Filipino neurologists and determine the factors affecting its adoption using the unified theory of acceptance and use of technology (UTAUT) model and its constructs, namely performance expectancy, effort expectancy, social influence, and facilitating conditions. Methods: This was a cross-sectional survey conducted online last October 2020 involving adult and pediatric neurologists in the Philippines. The internal consistency of the questionnaire adapted from UTAUT model was determined using Cronbach's alpha. We performed logistic regression analysis to determine which constructs of the UTAUT model were significant factors on the intent to practice teleneurology. Results: The study yielded a 28.8% response rate. Among the respondents (n1 = 147), 95.2% (n2 = 140) practiced teleneurology during the pandemic, and 77.6% (n1 = 147) planned to continue it after the pandemic. Teleneurology was mostly done on an outpatient basis on social media platforms via videoconferencing due to easier access for both end-users. The UTAUT model explained 80.9% (95% CI 0.76, 0.86a) of the total variation. Performance expectancy and facilitating conditions affect the intent to use teleneurology. Conclusions: Due to the limited resources and knowledge of its practice, infrastructural support and benefit awareness campaigns would be beneficial to increase its adoption, especially in developing countries.

Objective: Bacterial meningitis is associated with high morbidity and mortality if not treated early. Due to the high disease burden, there are barriers in the provision of healthcare services for these patients, especially in low‐ to middle‐income countries, such as the Philippines. We aimed to give an overview of healthcare services delivery and identify gaps in the provision of care for patients with bacterial meningitis in the Philippines. Method: We conducted a scoping review on the available literature on the epidemiology, research, health services delivery, diagnostics and management of Filipino patients with bacterial meningitis. A qualitative summary of the results was conducted to provide an overview of the findings. Results: There is a paucity of epidemiological data and research on bacterial meningitis. Healthcare expenditure remains out‐of‐pocket, with limited coverage from the national health insurance programme. There is an inadequate number of neurologists as well as inequities in the distribution of manpower and facilities due to the devolution of the healthcare system. Diagnosis remains a challenge due to the inaccessibility of tests for CSF analysis. Costs of antibiotics, adjunctive treatment, neurosurgical interventions and rehabilitation are also prohibitive. Outbreaks can be prevented by strengthening existing surveillance systems and improving vaccination coverage against the most common causative organisms. Conclusion: Enormous challenges still exist with regards to health services delivery in patients with bacterial meningitis in the Philippines in terms of epidemiologic data and research, access to healthcare facilities and diagnostic tools, healthcare costs, surveillance systems and immunisation against causative pathogens.

Patients diagnosed with diabetes mellitus (DM) who are infected with severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) belong to the most vulnerable patient subgroups. Emerging data has shown increased risks of severe infections, increased in ICU admissions, longer durations of admission, and increased mortality among coronavirus disease 2019 (COVID-19) patients with diabetes. We performed a subgroup analysis comparing the outcomes of patients diagnosed with DM (n = 2191) versus patients without DM (n = 8690) on our data from our study based on a nationwide, comparative, retrospective, cohort study among adult, hospitalized COVID-19 patients involving 37 hospital sites from around the Philippines. We determined distribution differences between two independent samples using Mann–Whitney U and t tests. Data on the time to onset of mortality, respiratory failure, intensive care unit (ICU) admission were used to build Kaplan–Meier curves and to compute for hazard ratios (HR). The odds ratios (OR) for longer ventilator dependence, longer ICU stay, and longer hospital stays were computed via multivariate logistic regression. Adjusted hazard ratios (aHR) and ORs (aOR) with 95% CI were calculated. We included a total of 10,881 patients with confirmed COVID-19 infection (2191 have DM while 8690 did not have DM). The median age of the DM cohort was 61, with a female to male ratio of 1:1.25 and more than 50% of the DM population were above 60 years old. The aOR for mortality was significantly higher among those in the DM group by 1.46 (95% CI 1.28–1.68; p < 0.001) as compared to the non-DM group. Similarly, the aOR for respiratory failure was also significantly higher among those in the DM group by 1.67 (95% CI 1.46–1.90). The aOR for developing severe COVID-19 at nadir was significantly higher among those in the DM group by 1.85 (95% CI 1.65–2.07; p < 0.001). The aOR for ICU admission was significantly higher among those in the DM group by 1.80 (95% CI 1.59–2.05) than those in the non-DM group. DM patients had significantly longer duration of ventilator dependence (aOR 1.33, 95% CI 1.08–1.64; p = 0.008) and longer hospital admission (aOR 1.13, 95% CI 1.01–1.26; p = 0.027). The presence of DM among COVID-19 patients significantly increased the risk of mortality, respiratory failure, duration of ventilator dependence, severe/critical COVID-19, ICU admission, and length of hospital stay.

Background: Pharmacologic treatment of vestibular schwannomas (VSs) may increase the success of conservative management for small lesions, and offer an alternative to surgery and stereotactic radiotherapy in symptomatic cases in the high-risk population. Agents that have been studied include aspirin (ASA), but the results of the preliminary studies have been conflicting. In this study, we aimed to systematically review the evidence on the effect of ASA intake on tumor growth in patients with VSs. Methods: Pubmed, Cochrane, Scopus, Embase, ClinicalTrials.gov, and Web of Science were searched for studies comparing VS tumor growth in patients with aspirin intake and those without. Random-effect meta-analysis was used to evaluate the outcomes in terms of linear and/or volumetric tumor growth. Results: Four retrospective cohort studies were included in the meta-analysis. No significant difference was found in tumor growth between VS patients with aspirin intake and those without. This result held true for the analysis of linear tumor growth (OR 1.23; 95% CI 0.49, 3.10), volumetric tumor growth (OR 1.41; 95% CI 0.36, 5.59), and both combined (OR 1.02; 95% CI 0.56, 1.86). Conclusions: Our meta-analysis suggests that there is insufficient evidence to recommend ASA therapy in patients with VSs. High-quality randomized controlled trials are warranted to determine the efficacy of this drug in reducing VS tumor growth. [ABSTRACT FROM AUTHOR]

Our study aimed to determine the effects of new-onset neurological symptoms (NNS) on clinically relevant outcomes in hospitalized patients with COVID-19 infection. We conducted a nationwide, comparative, retrospective, cohort study among adult, hospitalized COVID-19 patients involving 37 hospital sites from various regions in the Philippines. We included a total of 10,881 patients with confirmed COVID-19 infection (2008 had NNS while 8873 did not have NNS). The adjusted hazard ratios (aHRs) for mortality among the mild and severe cases were significantly higher by 1.660 (95% CI 1.132–2.435) and by 1.352 (95% CI 1.042–1.752), respectively, in the NNS group compared to those in the non-NNS group. The aHRs for respiratory failure in the NNS group were significantly increased by 1.914 (95% CI 1.346–2.722), by 1.614 (95% CI 1.260–2.068), and by 1.234 (95% CI 1.089–1.398) among the mild, severe, and critical cases, respectively. The aHRs for ICU admission in the NNS group were still significantly higher by 1.973 (95% CI 1.457–2.673) and by 1.831 (95% CI 1.506–2.226) among the mild and severe cases, respectively. Patients who had NNS were not significantly associated with a longer duration of ventilator dependence (adjusted odds ratio (aOR) 0.954, 95% CI 0.772–1.179), longer ICU stay (aOR 0.983, 95% CI 0.772–1.252) and longer hospital admission (aOR 1.045, 95% CI 0.947–1.153). The presence of NNS significantly increases the risk of mortality, respiratory failure and ICU admission among COVID-19 patients.

Achievement of universal eradication of paralytic poliomyelitis has remained a challenge. Despite the general decline in cases, multiple outbreaks attributed to poor vaccination still occur. Noncompliance from vaccination can be improved through education on various media platforms. In the internet age, online health-seeking behavior plays a significant role in this regard. Hence, our study investigated the association between global online search interest in polio with the number of polio cases and vaccination coverage. This infodemiological and ecological study utilized Google Trends' search volume index (SVI) for "polio" and the World Health Organization data on the number of polio cases (PC) and vaccine coverage rate (VCR) per country between 2006 and 2019. Associations between SVI for "polio" with PC and with VCR were evaluated. From the years 2006 to 2019, the global inquiry for this term was highest (i.e., SVI at 100) last October 2018. There was a direct correlation between the SVI for "polio" and PC while there was an inverse relationship between SVI and VCR per country per year. Both relationships have weak to moderate strength of associations. Based on our models, a one-unit increase in the SVI leads to a 3.8% increase in the number of polio cases. On the other hand, a one-unit increase in the SVI leads to a 0.01% decrease in the VCR. Conclusions: Dynamic changes in global SVIs for polio may reflect fluctuations in the number of polio cases and rates of vaccine coverage. Our study brings into light the largely untapped and potential use of online search behavior for polio to anticipate changes in PC and VCR in real-time. What is Known: •Parental vaccine hesitancy is a strong hindrance to the eradication of vaccine-preventable diseases. •The internet is a major source of information that modifies this attitude. What is New: •Internet health-seeking behavior can be measured using Google Trends' search volume index and can be used to correlate to certain aspects of public health determinants of a certain disease. •Google Trends' search volume index correlates with the number of polio cases/immunization rates, and this provides a basis for considering public health measures online.

Because ventriculoperitoneal shunt (VPS) insertion for patients with hydrocephalus from tuberculous meningitis (TBM) can be complicated by shunt infection and malfunction, endoscopic third ventriculostomy (ETV) has been proposed as an alternative. The aim of this review was to determine the success, technical failure, and complication rates of ETV in TBM in a meta-analysis and determine which factors are predictive of outcome. The PubMed, Scopus, and CENTRAL databases were searched from inception to April 2020 for case series, cohort studies, or randomized controlled trials reporting success, technical failure, or complication rates. For studies with individual patient data available, logistic regression analysis was done to determine whether age, sex, clinical grade, and type of hydrocephalus on imaging was predictive of outcome. Eight studies with a total of 174 patients were included in the review. Using random-effects modeling, the pooled estimate of success rate was 59% (95% CI 50–68%), with low heterogeneity (I2 = 30%). The technical failure and complication rates were 5% and 15%, respectively, but these variables had moderate heterogeneity. In 36 patients with individual patient data, a non-communicating type of hydrocephalus on imaging was associated with an odds ratio of 5.90 (95% CI 1.1–32.9, p = 0.043) for success. In summary, ETV for TBM had a pooled success rate of 59%, technical failure rate of 5%, and complication rate of 15%. An imaging finding of non-communicating hydrocephalus was associated with increased success. High-quality randomized, prospective studies using VPS insertion as control are needed to further define the role of ETV in TBM. [ABSTRACT FROM AUTHOR]

Background: Although headache is one of the most common neurologic conditions with a high disease burden, primary data on headache research from Southeast Asia (SEA) was hypothesized to be inadequate. This study aimed to evaluate research productivity among the different countries in SEA and to determine the association between specific bibliometric indices and socioeconomic factors. Methods: A systematic search was conducted until June 10, 2020 in Scopus, PubMed, Embase, Cochrane Central Register of Controlled Trials, and Index Medicus for South-East Asia Region to include all primary headache studies on migraine, tension-type headache, and trigeminal autonomic cephalalgia, with at least one author affiliated with a SEA country. Bibliometric indices, such as the number of publications and PlumX metrics, were obtained and correlated with the country-specific socioeconomic factors. Results: We identified 153 articles. Most of the publications (n = 43, 28.1%) were epidemiologic studies and case reports/series (n = 25, 16.3%). Migraine was the most studied primary headache subtype. Malaysia, Singapore, and Thailand were the major contributors to primary headache research in SEA. Only the percent gross domestic product for research and development correlated significantly with research productivity. Conclusion: Despite the high global burden of disease, research productivity on primary headache was low in SEA. The move towards a knowledge-based economy may drive research productivity in SEA.

Background: The internet has made significant contributions towards health education. Analyzing the pattern of online behavior regarding meningitis and vaccinations may be worthwhile. It is hypothesized that the online search patterns in meningitis are correlated with its number of cases and the search patterns of its related vaccines.Methods: This was an infodemiological study that determined the relationship among online search interest in meningitis, its worldwide number of cases and its associated vaccines. Using Google Trends™ Search Volume Indices (SVIs), we evaluated the search queries "meningitis," "pneumococcal vaccine," "BCG vaccine," "meningococcal vaccine" and "influenza vaccine" in January 2021, covering January 2008 to December 2020. Spearman rank correlation was used to determine correlations between these queries.Results: The worldwide search interest in meningitis from 2008 to 2020 showed an average SVI of 46 ± 8.8. The most searched topics were symptoms, vaccines, and infectious agents with SVIs of 100, 52, and 39, respectively. The top three countries with the highest search interest were Ghana, Kazakhstan, and Kenya. There were weak, but statistically significant correlations between meningitis and the BCG (ρ = 0.369, p < 0.001) and meningococcal (ρ = 0.183, p < 0.05) vaccines. There were no statistically significant associations between the number of cases, influenza vaccine, and pneumococcal vaccine.Conclusion: The relationships among the Google SVIs for meningitis and its related vaccines and number of cases data were inconsistent and remained unclear. Future infodemiological studies may expand their scopes to social media, semantics, and big data for more robust conclusions. [ABSTRACT FROM AUTHOR]

Background: Despite the expanding literature that discusses insights into the clinical picture and mechanisms by which the SARS-CoV-2 virus invades the nervous system, data on the neuropathologic findings of patients who died following SARS-CoV-2 infection is limited. Methods: A broad literature search was done for published articles that reported on histopathological findings of the brain in patients with COVID-19 in PubMed by MEDLINE, Embase, CENTRAL by the Cochrane Library, and SCOPUS from December 31, 2019 to October 31, 2020. Results: The systematic literature search strategy used resulted in a total of 1608 articles of which 14 were included in the analysis (PROSPERO registration number: CRD42020221022). There were ten case series, two case reports, one retrospective cohort, and one prospective cohort. The age of the patients ranged between 38 and 90 years old, most of them older than 65 years old (n=66, 45.2%) and males (n=79, 54.1%). Most tested negative in SARS-CoV-2 immunohistochemistry (n=70, 47.9%). The striking pathologic changes included diffuse edema (n=25, 17.1%), gliosis with diffuse activation of microglia and astrocytes (n=52, 35.6%), infarctions involving cortical and subcortical areas of the brain (n=4, 2.7%), intracranial bleed (subarachnoid hemorrhage and punctate hemorrhages) (n=18, 12.4%), arteriosclerosis (n=43, 29.5%), hypoxic-ischemic injury (n=41, 28.1%), and signs of inflammation (n=52, 35.6%). The cause of death was attributed to the cardiorespiratory system (n=66, 45.2%). Conclusions: The neuropathologic changes observed likely represent direct cytopathic effects and indirect effects secondary to host-specific inflammatory response induced by the viral infection. Further studies however are required to better elucidate the pathologic mechanism. [ABSTRACT FROM AUTHOR]

Background: Multiple sclerosis (MS), a disabling demyelinating disease of the central nervous system, is associated with cognitive impairment, spasticity, and fatigue. There are still no established guidelines on the management of MS-related sequela. Memantine has the potential to reduce glutamate toxicity, thereby reducing consequent cognitive impairment, spasticity, and fatigue. Objectives: This study aims to determine the efficacy and safety of memantine in preventing cognitive impairment, reducing spasticity and fatigue, and controlling disability in MS patients through a review of relevant randomized trials. Methods: MEDLINE, CENTRAL, Scopus, Embase, LILACS, ClinicalTrials.gov, and HERDIN were searched from inception to May 2020 for relevant trials. Results: The search yielded 203 articles; four studies were included in the analysis. Pooled evidence shows that memantine compared with placebo does not significantly improve PASAT, ASS, MFIS, and EDSS scores of patients with MS. Memantine is associated with mild adverse drug events such as dizziness, fatigue, and anxiety. Conclusion: There is not enough evidence to support the efficacy of memantine in preventing cognitive decline, controlling spasticity, reducing fatigue, and preventing disability. Future researches should consider the different MS subtypes, effect of co-administration of disease-modifying therapies, longer duration of administration, and more sensitive outcome measures to evaluate the potential benefit of memantine in MS.

Background: The status of research and scientific outputs with regards to bacterial central nervous system (CNS) infection in southeast Asia (SEA) is unknown. This study aimed to analyze and compare bacterial CNS infection research output of SEA countries in terms of bibliometric indices.Methods: The major electronic databases (MEDLINE, Scopus, Embase, CENTRAL, Clinicaltrials.gov and WPRIM) were searched for studies on bacterial CNS infection in SEA until August 31, 2020. Frequencies, percentages and Spearman's rho correlations were used.Results: There was a total of 648 unique studies on bacterial CNS infection in SEA and it was 657 when double-counted (collaborative studies between SEA countries). Thailand (n=148, 22.5%) and Vietnam (n=142, 21.6%) had the highest number of publications. The most common type of research publication was the case report / case series (n=160, 24.7%). Tuberculous meningitis/tuberculoma (n=176, 26.7%) was the most common topic. This study showed that the %GDP for research and development (R&D) was associated with a higher number of research output. However, the GDP per capita was not associated with any of the bibliometric indices. The total number of neurologists was associated with all of the bibliometric analysis.Conclusion: Bacterial CNS infection research output in SEA countries was low in terms of quantity. The %GDP for R&D was associated with the number of research publications. The total number of neurologists was associated with all of the bibliometric indices. [ABSTRACT FROM AUTHOR]

Background: There is an unmet need to assess research productivity from southeast Asia (SEA) regarding primary central nervous system (CNS) tumors. The country's economy, landscape of neurology practice, and disease burden are hypothesized to correlate with scientific output. This study aimed to objectively measure the impact of published studies on primary brain tumors in SEA and to assess for correlation with socioeconomic determinants and burden of disease. Methods: We systematically searched electronic databases for relevant articles from SEA on primary CNS tumor until July 31, 2020. Bibliometric indices were reported and subjected to correlational analysis with population size, gross domestic product (GDP) per capita, percentage (%) GDP for research and development (R&D), total number of neurologists, disease incidence, deaths, and disability-adjusted life years. Results: A total of 549 articles were included, consisting primarily of case reports (n=187, 34.06%) and discussed gliomas (n=195, 35.52%). Singapore published the most number of the articles (n=246, 44.8%). Statistical analysis showed a positive correlation between %GDP for R&D and total publication. Additionally, negative relationships were noted between burden of disease and total neurologist with most bibliometric indices. However, GDP per capita was not correlated with measures for research productivity. Conclusion: The low impact of scientific output on primary CNS tumors in SEA does not address the growing epidemiology and burden of this disease. An increase in the GDP growth and financial and manpower investment to R&D may significantly improve research productivity in SEA. [ABSTRACT FROM AUTHOR]

Background: Despite being known abroad as a viable alternative to face-to-face consultation and therapy, telerehabilitation has not fully emerged in developing countries like the Philippines. In the midst of the coronavirus disease 2019 (COVID-19) pandemic, wherein social distancing disrupted the in-clinic delivery of rehabilitation services, Filipinos attempted to explore telerehabilitation. However, several hindrances were observed especially during the pre-implementation phase of telerehabilitation, necessitating a review of existing local evidences. Objective: We aimed to determine the challenges faced by telerehabilitation in the Philippines. Method: We searched until March 2020 through PubMed, Scopus, Embase, Cochrane Library, and HeRDIN for telerehabilitation-related publications wherein Filipinos were involved as investigator or population. Because of the hypothesized low number of scientific outputs on telerehabilitation locally, we performed handsearching through gray literature and included relevant papers from different rehabilitation-related professional organizations in the Philippines. We analyzed the papers and extracted the human, organizational, and technical challenges to telerehabilitation or telehealth in general. Results: We analyzed 21 published and 4 unpublished papers, which were mostly reviews (8), feasibility studies (6), or case reports/series (4). Twelve out of 25 studies engaged patients and physicians in remote teleconsultation, teletherapy, telementoring, or telemonitoring. Patients sought telemedicine or telerehabilitation for general medical conditions (in 3 studies), chronic diseases (2), mental health issues (2), orthopedic problems (2), neurologic conditions (1), communication disorders (1), and cardiac conditions (1). Outcomes in aforementioned studies mostly included telehealth acceptance, facilitators, barriers, and satisfaction. Other studies were related to telehealth governance, legalities, and ethical issues. We identified 18 human, 17 organizational, and 18 technical unique challenges related to telerehabilitation in the Philippines. The most common challenges were slow internet speed (in 10 studies), legal concerns (9), and skepticism (9). Conclusion: There is paucity of data on telerehabilitation in the Philippines. Local efforts can focus on exploring or addressing the most pressing human, organizational, and technical challenges to the emergence of telerehabilitation in the country. [ABSTRACT FROM AUTHOR]

Background: Scientific output in Southeast Asia (SEA) on the topic of dementia is postulated to be low in quality and quantity. It is also speculated that certain socioeconomic variables and measures of disease burden for dementia may play a significant role in driving the research output of a particular country.Objective: This study aimed to determine the research impact of published journal articles on dementia in SEA and its association with country-level socioeconomic factors and measures of disease burden for dementia.Methods: A systematic search was conducted using electronic healthcare databases. We included articles published on dementia until August 2019 with at least 1 author affiliated with any SEA institution. We obtained bibliometric indices, relevant socioeconomic factors, and measures of disease burden for dementia from published sources.Results: One thousand six articles fulfilled the inclusion criteria. The majority of publications were related to Alzheimer's disease (n = 775, 77.0%). Singapore contributed the highest number of publications (n = 457, 45.4%). Gross domestic product (GDP) per capita, % GDP for research and development, and total neurologists significantly correlated with several bibliometric indices. On the other hand, the measures of disease burden for dementia in SEA countries were not significantly associated with research productivity.Conclusion: Research productivity in SEA on dementia has substantially increased in recent years. Augmenting GDP per capita and expanding the apportionment of resources to research and development (R&D) may have a significant role in the advancement of dementia research in SEA.

Background: A critical strategy in the management of Alzheimer's disease (AD) is optimizing the effects of currently available pharmacologic therapies such as citicoline (CC).Objective: The purpose of this study was to determine the effects of CC as adjunct therapy to cholinesterase inhibitors (AChEI) in the treatment of AD.Methods: We identified relevant studies by electronic search until April 2020. We considered studies with a comparator group that enrolled elderly patients with a diagnosis of AD and employed CC as an adjunct therapy to AChEIs compared to AChEI monotherapy or comparisons of different AChEIs combined with CC. Methodological quality assessment was done using the Newcastle-Ottawa Scale.Results: Out of 149 articles identified, two retrospective cohort studies involving 563 elderly patients affected with AD were included. After 3 months and 9 months, better Mini-Mental Status Examination scores were observed in the "AChEIs + CC" group versus "AChEIs alone" group. CC combined with donepezil may be better in improving cognition than when combined with rivastigmine. No significant difference was noted in terms of activities of daily living (ADL) and instrumental-ADL. Neuropsychiatric Inventory and Geriatric Depression Scale-short form scores appeared to be lower in the combination treatment versus monotherapy. The adverse events of combined treatment were self-limiting and included occasional excitability, gastric intolerance, and headache.Conclusion: Limited evidence from pooled data of two observational studies suggests that CC used in adjunct with AChEIs in the treatment of AD was well-tolerated and showed improvement in cognition, mood, and behavioral symptoms compared to treating with AChEIs alone.
