AbstractObjectiveTo compare the difference between severe and non-severe COVID-19 pneumonia and figure out the potential symptoms lead to severity.MethodsArticles from PubMed, Embase, Cochrane database, and google up-to 24 February 2020 were systematically reviewed. Eighteen Literatures were identified with cases of COVID-19 pneumonia. The extracted data includes clinical symptoms, age, gender, sample size and region et al were systematic reviewed and meta analyzed.Results14 eligible studies including 1,424 patients were analyzed. Symptoms like fever (89.2%), cough (67.2%), fatigue (43.6%) were common, dizziness, hemoptysis, abdominal pain and conjunctival congestion/conjunctivitis were rare. Polypnea/dyspnea in severe patients were significantly higher than non-severe (42.7% vs.16.3%, P<0.0001). Fever and diarrhea were higher in severe patients(p=0.0374and0.0267). Further meta-analysis showed incidence of fever(OR1.70,95%CI 1.01-2.87), polypnea/dyspnea(OR3.53, 95%CI 1.95-6.38) and diarrhea(OR1.80,95%CI 1.06-3.03) was higher in severe patients, which meant the severe risk of patients with fever, polypnea/dyspnea, diarrhea were 1.70, 3.53, 1.80 times higher than those with no corresponding symptoms.ConclusionsFever, cough and fatigue are common symptoms in COVID-19 pneumonia. Compared with non-severe patients, the symptoms as fever, polypnea/dyspnea and diarrhea are potential symptoms lead to severity.

Objective To systematically review the literature to determine the difference in complications between standard twill and Velcro ties following pediatric tracheostomy. Data Sources MEDLINE, Embase, the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, Web of Science, and CINAHL Plus were searched up to August 2020. Review Methods Two authors independently screened articles for eligibility. Retrospective and prospective studies were included as long as there was a direct comparison between twill and Velcro ties. Quantitative and qualitative analysis was performed. The main outcomes were skin-related complications and accidental decannulation. Results Three studies were included in the final analysis: 1 randomized prospective trial and 2 retrospective studies. There were 238 patients total (137 twill, 101 Velcro). Combined analysis showed skin-related complications in 23% of the Velcro group and 44% of the twill group. Meta-analysis for skin-related complications showed no significant difference when comparing Velcro with standard twill ties (risk ratio, 0.53 [95% CI, 0.24-1.17]; P = .12, n = 238 participants from 3 studies, I2 = 66%). Accidental decannulation rates were overall low and comparable between groups (1.0% of twill, 1.4% of Velcro). Conclusion Based on limited data, skin-related complications were not statistically different between Velcro and twill ties. Accidental decannulation is rare with Velcro and standard twill ties, and both are viable options following pediatric tracheostomy.

In order to determine the impact of garlic on total cholesterol (TC), TAG levels, as well as LDL and HDL, and establish if any variables have an impact on the magnitude of this effect, a meta-analysis was conducted. A systematic literature search of MEDLINE, CINAHL and the Cochrane Database from the earliest possible date through to November 2007 was conducted to identify randomised, placebo-controlled trials of garlic that reported effects on TC, TAG concentrations, LDL or HDL. The weighted mean difference of the change from baseline (with 95 % CI) was calculated as the difference between the means in the garlic groups and the control groups using a random-effects model. Subgroup and sensitivity analyses were performed to determine the effects on type, brand and duration of garlic therapy as well as baseline TC and TAG levels, the use of dietary modification, and study quality on the meta-analysis's conclusions. Twenty-nine trials were included in the analysis. Upon meta-analysis garlic was found to significantly reduce TC ( − 0·19; 95 % CI − 0·33, − 0·06 mmol/l) and TAG ( − 0·11; 95 % CI − 0·19, − 0·06 mmol/l) but exhibited no significant effect on LDL or HDL. There was a moderate degree of statistical heterogeneity for the TC and TAG analyses. Garlic reduces TC to a modest extent, an effect driven mostly by the modest reductions in TAG, without appreciable LDL lowering or HDL elevation. Higher baseline line TC levels and the use of dietary modification may alter the effect of garlic on these parameters. Future studies should be conducted evaluating the impact of adjunctive garlic therapy with fibrates or statins on TAG concentrations.

Living With Hiv

Research Purpose: Findings from existing studies have shown conflicting evidence concerning the risk of severe COVID-19 and death from COVID-19 in people living with HIV (PLHIV) compared to people without HIV. The aim of our review is to compare mortality, hospitalization, and the need for intensive care services due to COVID-19 between PLHIV and individuals without HIV based on data from the existing literature. Methods: A search in major databases of preprints was carried out and eligible studies were screened and selected. From each study, data on numbers of PLHIV and individuals without HIV were extracted. Study quality was assessed using the MethodologicAl STandard for Epidemiological Research (MASTER) scale. Data synthesis used a bias adjusted model where age and geographical subgroups were analysed. Results: From the 2757 records identified, 11 studies were included. The total participants were 1 268 676, of which 13 886 were PLHIV. Overall, the estimated effect of HIV on mortality suggested some worsening (OR 1.3, 95% CI: 0.9 – 2.0, I2 = 78.6%) with very weak evidence against the model hypothesis at this sample size. However, in individuals aged <60 years, the estimated effect on mortality suggested more worsening in PLHIV (OR 2.7, 95% CI: 1.1 -6.5, I2 = 95.7%) with strong evidence against the model hypothesis at this sample size. HIV was also associated with an estimated effect on hospitalization for COVID-19 that suggested worsening (OR 1.6, 95% CI: 1.3-2.1, I2 = 96.0%) with strong evidence against the model hypothesis at this sample size. Conclusion: People living with HIV have higher risk of death and hospitalisation from COVID-19, compared to individuals without HIV with the difference exaggerated in those younger than 60 years old. Our findings suggest that PLHIV are at higher risk than the general population and should be prioritized for vaccine coverage and monitoring if diagnosed with COVID-19.

Objective: The prognosis of mild and severe patients has prominent differences during the prevalence of COVID-19, and it will be significant to identify patients' potential risk of progressing to severe cases according to their first clinical presentations. Therefore, we aim to review the clinical symptoms of the COVID-19 epidemic systematically.Methods:We searched PubMed, Embase, Web of Science, and CNKI (Chinese Database) for studies about the clinical features of COVID-19 in China from March 18 to April 18. Then we used REVMAN to conduct a meta-analysis.Results: After screening, 20 articles including 3,326 COVID-19 confirmed cases were selected from 142 articles we retrieved at the beginning of our research. We divided all the cases into a severe group (including severe and critically severe patients) and a mild group according to the “Diagnosis and Treatment Protocol for Novel Coronavirus Infection-Induced Pneumonia” version 4 (trial). Of all the initial symptoms (including fever, cough, abdominal pain, anorexia, chest tightness, diarrhea, dyspnea, expectoration, fatigue, headache, hemoptysis, myalgia, nausea or vomiting, and pharyngalgia) we studied, we found that cough (odds ratio [OR] = 1.4, 95% confidence interval [CI]: 1.2–1.7; p &lt; 0.001), fever (OR = 1.5, 95% CI: 1.2–1.9; p &lt; 0.001), dyspnea (OR = 6.2, 95% CI: 3.6–10.6; p &lt; 0.001), diarrhea (OR = 2.6, 95% CI: 1.3–4.9; p &lt; 0.001), fatigue (OR = 2.1, 95% CI: 1.3–3.3; p &lt; 0.01), expectoration (OR = 1.7, 95% CI: 1.2–2.6; p &lt; 0.01), myalgia (OR = 1.6, 95% CI: 0.8–3.1; p &lt; 0.001), hemoptysis (OR = 4.0, 95% CI: 1.5–11.3; p &lt; 0.001), abdominal pain (OR = 7.5, 95% CI: 2.4–23.4; p &lt; 0.001), and anorexia (OR = 2.8, 95% CI: 1.5–5.1; p &lt; 0.001) had a different distribution in two groups and were statistically significant (p &lt; 0.05).Conclusion:COVID-19 patients whose initial manifestation is dyspnea, hemoptysis, anorexia, diarrhea, or fatigue, especially abdominal pain should be closely monitored to prevent disease deterioration.

Oseltamivir delivers modest clinical advantages to children with influenza when started within 48 hours of symptom beginning. Nevertheless, effectiveness and safety stay controversial. We conducted the current meta-analysis using a comprehensive search of EMBASE, MEDLINE, PubMed, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials till 15 February 2018 for randomized controlled trials of oseltamivir therapy in children. Four studies met the search criteria. Overall, oseltamivir treatment significantly reduced the duration of illness in the ITTI population (RMST difference, -18.2 hours; 95% CI, −32.2 to −0.6 hours). In trials that enrolled patients without asthma, the difference was larger (RMST difference −26.7 hours; 95% CI, −49.8 to −6.1 hours).Risk of otitis media was 34% lower in the ITTI population. Vomiting was the only adverse event with a significantly higher risk in the treatment group. Regardless of considerable heterogeneity in pediatric trials, we found that treatment with oseltamivir treatment started within 24 hours of symptom onset provides substantial benefits to children with influenza infection and lowered the risk of developing otitis media.

Summary: Our meta-analysis focused on the relationship between homocysteine (Hcy) level and the incidence of aneurysms and looked at the relationship between smoking, hypertension and aneurysms. A systematic literature search of Pubmed, Web of Science, and Embase databases (up to March 31, 2020) resulted in the identification of 19 studies, including 2,629 aneurysm patients and 6,497 healthy participants. Combined analysis of the included studies showed that number of smoking, hypertension and hyperhomocysteinemia (HHcy) in aneurysm patients was higher than that in the control groups, and the total plasma Hcy level in aneurysm patients was also higher. These findings suggest that smoking, hypertension and HHcy may be risk factors for the development and progression of aneurysms. Although the heterogeneity of meta-analysis was significant, it was found that the heterogeneity might come from the difference between race and disease species through subgroup analysis. Large-scale randomized controlled studies of single species and single disease species are needed in the future to supplement the accuracy of the results.

Eye Movements During Reading

Abstract. We report the results of a meta-analysis of 22 experiments comparing the eye movement data obtained from young ( Mage = 21 years) and old ( Mage = 73 years) readers. The data included six eye movement measures (mean gaze duration, mean fixation duration, total sentence reading time, mean number of fixations, mean number of regressions, and mean length of progressive saccade eye movements). Estimates were obtained of the typified mean difference, d, between the age groups in all six measures. The results showed positive combined effect size estimates in favor of the young adult group (between 0.54 and 3.66 in all measures), although the difference for the mean number of fixations was not significant. Young adults make in a systematic way, shorter gazes, fewer regressions, and shorter saccadic movements during reading than older adults, and they also read faster. The meta-analysis results confirm statistically the most common patterns observed in previous research; therefore, eye movements seem to be a useful tool to measure behavioral changes due to the aging process. Moreover, these results do not allow us to discard either of the two main hypotheses assessed for explaining the observed aging effects, namely neural degenerative problems and the adoption of compensatory strategies.

We cannot be sure exactly what will happen, we can only estimate by using a particular method, where each method must have the formula to create a regression equation and a formula to calculate the confidence level of the estimated value. This paper conveys a method of estimating the future values, in which the formula for creating a regression equation is based on the assumption that the future value will depend on the difference of the past values divided by a weight factor which corresponding to the time span to the present, and the formula for calculating the level of confidence is to use "the Haryadi Index". The advantage of this method is to remain accurate regardless of the sample size and may ignore the past value that is considered irrelevant.
