Botulinum Toxin (BTX) has been found to have anti-spasm and analgesic effects. The utility of BTX after conventional hemorrhoidectomy remains unclear. Thus, a systematic review and meta-analysis are required to find out its utility after conventional hemorrhoidectomy.Using specific keywords, we comprehensively go through the potential articles on PubMed, ClinicalTrials.gov, and Europe PMC sources until March 27Five clinical trial studies with a total of 260 patients undergoing hemorrhoidectomy were included in the analysis Our pooled analysis revealed that BTX injection after hemorrhoidectomy was associated with lower VAS at 24 h post-operative [Mean Difference -1.35 (95% CI -1.90, -0.80),BTX sphincter injection may offer some benefit after conventional hemorrhoidectomy in reducing pain from the first day after the procedure and promoting wound healing without complication. Further randomized clinical trials are still needed to confirm the results of our study.

Migraine, the third most common neurological disorders worldwide, can cause significant burden to the patients. Currently, it has been found that calcitonin gene-related peptide (CGRP) has a significant role in pathophysiology of migraine. This study sought to analyse the efficacy and safety of eptinezumab, one of the CGRP-monoclonal antibody as preventive treatment for episodic/chronic migraine. Specific keywords were used to comprehensively go through the potential articles on ClinicalTrials.gov, Europe PMC, Scopus and PubMed databases until April 2022. All published randomized clinical trials (RCTs) on eptinezumab and migraine were gathered. Statistical analysis was conducted by using Review Manager 5.4 and Comprehensive Meta-Analysis version 3 software. There were four RCTs with 2739 migraine patients in the meta-analysis. In terms of efficacy, our analysis revealed that eptinezumab corresponded with higher reduction in monthly migraine days from baseline to week 12 (standardized mean difference, -0.34 [95% confidence interval (CI), -0.41, -0.28], P 0.00001; I

Background: Hypertension and heart failure are known risk factors for coronavirus disease 2019 (COVID-19) severity and mortality outcomes. Beta-blocker is one of the drugs of choice to treat these conditions. The purpose of this study is to explore the relationship between pre-admission beta-blocker use and COVID-19 outcomes. Methods: PubMed and Europe PMC were used as the database for our search strategy by using combined keywords related to our aims until December 10th, 2020. All articles related to COVID-19 and beta-blocker were retrieved. Review Manager 5.4 and Comprehensive Meta-Analysis 3 software were used to perform statistical analysis. Results: A total of 43 studies consisting of 11,388,556 patients were included in our analysis. Our meta-analysis showed that the use of beta-blocker was associated with increased risk of COVID-19 [OR 1.32 (95% CI 1.02 – 1.70), p = 0.03, I2 = 99%, random-effect modelling], clinical progression [OR 1.37 (95% CI 1.01 – 1.88), p = 0.04, I2 = 89%, random-effect modelling], and mortality from COVID-19 [OR 1.64 (95% CI 1.22 – 2.19), p = 0.0009, I2 = 94%, random-effect modelling]. Meta-regression showed that the association with mortality outcome were influenced by age (p = 0.018) and hypertension (p = 0.005). Conclusions: The risk and benefits of using beta-blocker as a drug of choice to treat hypertensive patients should be put into account and reviewed individually case by case, knowing their association in higher incidence and severity of Covid-19 infections. Other first-line antihypertensive drugs may be considered as an alternative therapy if the risk of administering beta blockers outweigh the benefits in Covid-19 infection.

In December 2019, a novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) was initially reported in Wuhan, China. Previous epidemics including SARS and middle east respiratory syndrome raises concern that COVID-19 infection may pose a significant threat to the mental health of affected individuals. Studies and reviews have shown the acute psychiatric manifestations in COVID-19 patients, although long term psychiatric sequelae are predicted, there are only few review studies about the long term psychiatry outcome in COVID-19 survivors. Clinically significant post-traumatic stress disorder, anxiety, and/or depression among COVID-19 survivors during 14-90 d were observed following the diagnosis. Risk of anxiety or depression were higher in patients with more severe illness at 6 mo follow-up, early convalescence, and at 1 mo follow-up. Diagnosis of COVID-19 Led to more first diagnoses and relapses of psychiatric illness during the first 14-90 d after COVID-19 diagnosis. The possible underlying mechanisms of psychiatric sequelae in COVID-19 infection are neurotropism, immune response to SARS-CoV-2, hypothalamo-pituitary-adrenal axis hyperactivity, disrupted neuronal circuits in several brain regions, increased stress levels, neuroinflammation, and neuronal death. This study will review the psychiatric sequelae in previous coronavirus pandemics, current studies, risk factors, and thorough explanation on pathophysiology of the psychiatric sequalae in COVID-19 survivors.

Aim Delirium is a common presenting symptom among older patients.

Background: Coronavirus disease 2019 (COVID-19) is a pandemic disease that has significant implications on the global health burden. Currently, there is no widely accepted pharmacologic treatment for COVID-19. Remdesivir has been shown effective against various types of viruses, including coronaviruses. This study aimed at synthesizing the latest evidence regarding the effectiveness and safety of remdesivir as a potential treatment candidate against COVID-19. Methods: This systematic review has been registered in PROSPERO (CRD42020183707). A systematic search of the literature was conducted in PubMed, PubMed Central, and Google Scholar through June 5th, 2020. Statistical analysis was done by using the Review Manager 5.4 tool. The risk of bias was evaluated using the Revised Cochrane risk-of-bias tool for randomized trials (RoB 2) and GRADE analysis was performed to determine the certainty of the evidence. Results: Two studies with a total of 1,300 patients were included. Meta-analysis showed that remdesivir was associated with faster time to clinical improvement (MD -4.75 days; 95% CI -4.84 days to -4.65 days; p < 0.00001), reduction in mortality rate (RR 0.39; 95% CI 0.27 – 0.56; p < 0.00001) and fewer incidence of serious adverse events (RR 0.77; 95% CI 0.63 – 0.94; p = 0.01). GRADE analysis showed a high certainty for serious adverse events and moderate certainty for time to clinical improvement and mortality rate. Conclusion: Remdesivir is more effective and safer compared with standard care of treatment for the treatment of COVID-19 because it was associated with faster time to clinical improvement, reduction in mortality rate, and fewer incidence of serious adverse events.

Background: Sinovac was the first vaccine used in Indonesia against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, data regarding the effects of certain variables such as clinical demographics on antibody levels in individuals vaccinated with Sinovac are scarce. This study aimed to investigate the impact of gender and previous SARS-CoV-2 infection status on neutralizing antibody titers 1, 2, and 3 months after administration of the Sinovac vaccine.Method: A cross-sectional study was conducted from February to May 2021. Data on neutralizing antibody levels, previous SARS-CoV-2 infection status, and gender were retrieved from the monthly quantitative serology evaluation database of Siloam Hospitals Lippo Village, Tangerang, Indonesia. The role of each variable was analyzed using the t-test or Mann-Whitney U test, depending on data distribution.Result: Data from 350 participants were collected for the study. Participants with a history of a positive SARS-CoV-2 RT-PCR test had significantly higher neutralizing antibody titers in the first (144 U/mL, p = 0.036) and second months (144 U/mL, p = 0.005) after vaccination compared with those without a history of positive RT-PCR test. Female participants also had significantly higher neutralizing antibody titers in the first, second, and third months (43 U/mL, 42 U/mL, and 39 U/mL, respectively; p = 0.001, p = 0.002, and p = 0.003, respectively) after vaccination compared to males.Conclusion: COVID-19 survivor status and the female gender were associated with higher neutralizing antibody titers after Sinovac vaccine administration.

Background One of the drugs which is commonly used in diabetic patients is Dipeptidyl Peptidase-4 (DPP-4) inhibitor. Currently, the association between DPP-4 inhibitor and coronavirus disease 2019 (COVID-19) outcome is not yet established. This study aims to analyze the potential association between DPP-4 inhibitor and the composite poor outcome of COVID-19. Methods We systematically searched the PubMed and Europe PMC database using specific keywords related to our aims until November 29th, 2020. All articles published on COVID-19 and DPP-4 inhibitor were retrieved. Statistical analysis was done using Review Manager 5.4 and Comprehensive Meta-Analysis version 3 software. Results Our pooled analysis showed that DPP-4 inhibitor use was not associated with composite poor outcomes of COVID-19 [OR 1.09 (95% CI 0.93–1.28), p = 0.29, I2 = 0%, random-effect modelling], and its subgroup which comprised of severe COVID-19 [OR 1.07 (95% CI 0.87–1.31), p = 0.54, I2 = 0%, random-effect modelling], and mortality [OR 1.14 (95% CI 0.87–1.51), p = 0.35, I2 = 8%, random-effect modelling]. Meta-regression showed that the association was not influenced by age (p = 0.663), hypertension (p = 0.454), and admission blood glucose (p = 0.310). Subgroup analysis showed that the association was weaker in East Asian populations (OR 1.02) compared to European populations (OR 1.11). Conclusion DPP-4 inhibitor in diabetic patients did not alter the outcomes from COVID-19. Our study suggest that the use of DPP-4 inhibitor in COVID-19 patients with diabetes may still be continued according to the patients’ need.

Background Laboratory testing is commonly performed in patients with COVID-19. Each of the laboratory parameters has potential value for risk stratification and prediction of COVID-19 outcomes. This systematic review and meta-analysis aimed to evaluate the difference between these parameters in severe and nonsevere disease and to provide the optimal cutoff value for predicting severe disease. Method We performed a systematic literature search through electronic databases. The variables of interest were serum procalcitonin, albumin, C-reactive protein (CRP), D-dimer, and lactate dehydrogenase (LDH) levels in each group of severity outcomes from COVID-19. Results There were a total of 4848 patients from 23 studies. Our meta-analysis suggest that patients with severe COVID-19 infections have higher procalcitonin, (mean difference 0.07; 95% CI 0.05–0.10; p, Highlights • Currently, the cut-off value for laboratory markers to differentiate severity of COVID-19 is still unclear. • Our study suggest serum procalcitonin, albumin, CRP, D-dimer, and LDH can assist in differentiating the severity of COVID-19. • Physicians should check these laboratory parameters in COVID-19 patients for predicting the outcome of the disease.

Background: Fluvoxamine may be beneficial for the management of coronavirus disease 2019 (Covid-19) because of its effect on the sigma-1 receptor. Available evidence from randomized clinical trials (RCTs) has shown conflicting results. Objective: This study sought to analyze the efficacy and safety of fluvoxamine as an outpatient treatment for Covid-19. Methods: Using specific keywords, we comprehensively go through the potential articles on PubMed, Scopus, Europe PMC, and ClinicalTrials.gov sources until February 1, 2023. We collected all published clinical trials on fluvoxamine and Covid-19. We were using Review Manager 5.4 to conduct statistical analysis. Results: We include a total of 6 trials. Our pooled analysis revealed that fluvoxamine did not offer any significant benefit when compared with placebo in reducing the risk of clinical deterioration (risk ratio [RR] = 0.83; 95% CI: 0.65-1.06, P = 0.14, I2 = 29%), and hospitalization (RR = 0.80; 95% CI: 0.62-1.04, P = 0.09, I2 = 0%) of Covid-19 outpatients. The serious adverse events did not differ significantly between the 2 groups. Conclusions and Relevance: This study indicates that although safe, fluvoxamine was not effective for outpatient treatment of Covid-19. Until more evidence can be obtained from larger RCTs, our study did not encourage the use of fluvoxamine as routine management for patients with Covid-19.

The three most common comorbidities that are associated with increased mortality in COVID-19 patients are Hypertension, Diabetes, and Cardiovascular disease, Angiotensin-converting enzyme (ACE) inhibitors and Angiotensin II receptor blockers (ARB) are the drugs most commonly prescribed for the management of these diseases. Recent experimental study in animals and humans have found that SARS-CoV-2 uses ACE2 as the receptors for entry. Moreover, in an animal study, the use of ACE inhibitor/ARB increases the level of ACE2 expression that can lead to increased SARS-CoV-2 infectivity. On the other side, some evidences suggest that the ACE2 receptor is not necessary for SARS-CoV-2 entry into the cell and suggested that there is a cofactor that play part. Experimental studies in humans also showed that there is no association between ACE inhibitor/ARB with SARS-CoV-2 infectivity and mortality. In conclusion, there is still insufficient data to stop the use of inhibitor/ARB in SARS-CoV-2 patients. Therefore, we suggested that in line with the recommendations from ESC and AHA/ACC, the use of these two drugs in SARS-CoV-2 patients with cardiovascular comorbidity should still be continued.

Introduction Cachexia in cancer patients, especially in advanced stage, is recently known as an emerging problem. Cachexia occurs in about half of all patients with neoplastic disease. The diagnosis of cachexia needs comprehensive evaluation of body weight and body composition for several months. Cachexia will give negative impacts such as increased mortality, chemotoxicity, and decreased quality of life. Here, we review the current evidence describing the definition, stages, mechanisms, diagnosis and treatment of cachexia in cancer patients. Methods We identified 75 studies and/or review articles evaluating cachexia and weight loss in cancer patients by searching PubMed and EMBASE databases. Results Cachexia is reported across all stages and types of cancers. The most recent definition of cachexia is reported in a 2011 paper by International Consensus. The mechanism of cachexia in cancer is complex and involved many factors which elaborate together to produce cachexia. The diagnostic evaluation and cut-off measurement of cachexia, especially in cancer varied across studies. The loss of weight that happens during chemotherapy will make a poor prognosis. Cachexia can worsen chemotherapy toxicity. Combination of dietary modification and exercise with supplementation of medication that control appetite and inflammation are important in the management of cachexia in cancer patients. Conclusion Patients with cancer are the population at risk for developing cachexia before and after chemotherapy. Cachexia diagnosis needs evaluation of body weight and body composition. Nonpharmacological treatments, such as dietary modification and physical exercise, are the best strategy to reduce cachexia in cancer patients.

Our meta-analysis showed that dyslipidemia is associated with severe COVID-19 infections [RR 1.39 (95% CI 1.03–1.87), p = 0.03, I2 = 57%, random-effect modelling]. Conclusion Dyslipidemia increases the risk of the development of severe outcomes from COVID-19 infections. Patients with dyslipidemia should be monitored closely to minimize the risk of COVID-19., Highlights • Our meta-analysis showed that dyslipidemia is associated with severe COVID-19 infections. • Patients with dyslipidemia should be monitored closely to minimize the risk of COVID-19. • The presence of dyslipidemia should be considered for further risk stratification of COVID-19.

Background: Persons living with human immunodeficiency virus (PLWH) constitute a vulnerable population in view of their impaired immune status. At this time, the full interaction between HIV and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been incompletely described. Objective: The purpose of this study was to explore the impact of HIV and SARS-CoV-2 co-infection on mortality. Method: We systematically searched PubMed and the Europe PMC databases up to 19 January 2021, using specific keywords related to our aims. All published articles on coronavirus disease 2019 (COVID-19) and HIV were retrieved. The quality of the studies was evaluated using the Newcastle–Ottawa Scale for observational studies. Statistical analysis was performed with Review Manager version 5.4 and Comprehensive Meta-Analysis version 3 software. Results: A total of 28 studies including 18 255 040 COVID-19 patients were assessed in this meta-analysis. Overall, HIV was associated with a higher mortality from COVID-19 on random-effects modelling {odds ratio [OR] = 1.19 [95% confidence interval (CI) = 1.01–1.39], p = 0.03; I 2 = 72%}. Meta-regression confirmed that this association was not influenced by age ( p = 0.208), CD4 cell count ( p = 0.353) or the presence of antiretroviral therapy (ART) ( p = 0.647). Further subgroup analysis indicated that the association was only statistically significant in studies from Africa (OR = 1.13, p = 0.004) and the United States (OR = 1.30, p = 0.006). Conclusion: Whilst all persons ought to receive a SARS-CoV-2 vaccine, PLWH should be prioritised to minimise the risk of death because of COVID-19. The presence of HIV should be regarded as an important risk factor for future risk stratification of COVID-19.

Background Obstructive sleep apnea (OSA) is the most prevalent sleep-related breathing disorder which could impair someone's quality of life and is also associated with poor outcomes from many diseases. Currently, the evidence regarding the link between OSA and coronavirus disease 2019 (COVID-19) is still conflicting. This study aims to analyze the relationship between OSA and poor outcomes of COVID-19. Materials and Methods We systematically searched the PubMed and Europe PMC database using specific keywords related to our aims until December 10th, 2020. All articles published on COVID-19 and OSA were retrieved. The quality of the study was assessed using the Newcastle Ottawa Scale (NOS) tool for observational studies. Statistical analysis was done using Review Manager 5.4 software. Results A total of 21 studies with 54,276 COVID-19 patients were included in this meta-analysis. This meta-analysis showed that OSA was associated with composite poor outcome [OR 1.72 (95% CI 1.55 – 1.91), p < 0.00001, I2 = 36%, random-effect modelling] and its subgroup which comprised of severe COVID-19 [OR 1.70 (95% CI 1.18 – 2.45), p = 0.005], ICU admissions [OR 1.76 (95% CI 1.51 – 2.05), p < 0.00001], the need for mechanical ventilation [OR 1.67 (95% CI 1.48 – 1.88), p < 0.00001], and mortality [OR 1.74 (95% CI 1.39 – 2.19), p < 0.00001]. Conclusions Extra care and close monitoring should be provided to patients with OSA to minimize the risk of infections. Simple questionnaires such as STOP-Bang questionnaire can be used for screening patients who may be at risk for severe adverse outcomes.

AIDS Research and Human Retroviruses officially retracts the Instant Online/Just Accepted version of the article entitled, "Human Immunodeficiency Virus (HIV) and Outcomes from Coronavirus Disease 2019 (COVID-19) Pneumonia: A Meta-Analysis and Meta-Regression" (epub 27 Jan 2021; doi.org/10.1089/AID.2020.0307). A technical issue caused the accepted version to post online before all plagiarism checks were finalized. Those checks determined that there was too much duplication from previously published sources which prevented the continuance to final publication. The technical issue that caused the premature posting has since been corrected. AIDS Research and Human Retroviruses and its Publisher are committed to upholding the standards of scientific publishing and the community it serves. BACKGROUND: The number of positive and death cases from coronavirus disease 2019 (COVID-19) is still increasing until now. One of the most prone individuals, even in normal situations is patients with HIV. Currently, the evidence regarding the link between HIV and COVID-19 is still limited and conflicting. This study aims to analyze the relationship between HIV and poor outcomes of COVID-19 infection. METHODS: We systematically searched the PubMed and Europe PMC database using specific keywords related to our aims until January 12th, 2021. All articles published on COVID-19 and HIV were retrieved. The quality of the study was assessed using the Newcastle Ottawa Scale (NOS) tool for observational studies. Statistical analysis was done using Review Manager 5.4 and Comprehensive Meta-Analysis version 3 software. RESULTS: A total of 38 studies with 18,271,025 COVID-19 patients were included in this meta-analysis. This meta-analysis showed that HIV was not associated with composite poor outcome [OR 1.08 (95% CI 0.95 - 1.23), p = 0.26, I2 = 68%, random-effect modelling]. Meta-regression showed that the association with composite poor outcome was influenced by hypertension (p < 0.00001) and diabetes (p = 0.0007). Subgroup analysis which involves only studies from African region showed that HIV was associated with composite poor outcomes [OR 1.11 (95% CI 1.03 - 1.21), p = 0.01, I2 = 0%, random-effect modelling]. CONCLUSIONS: Patients with HIV should still be considered as a population for whom precautions are needed to prevent the COVID-19. The availability of antiretroviral therapy should be ensured.
