Background: Exercise is believed to play an important role in maintaining functionality in patients with HIV and it is thought that researchers are increasingly interested in this field. We aimed to shed light on the historical development of research on HIV and exercise by utilizing visual mapping method. Methods: Overall, 1051 articles retrieved from Web of Science (WoS) core database were analyzed according to the publication year and language, number of issues, citation, country collaborations, co-citation networks and concept–topic trends by using CiteSpace software. Results: The United States played a key role in country collaborations, and had the highest citation burst. The most cited studies were meta-analysis studies. The studies gathered mainly around the clusters named “physical activity” and “metabolic abnormalities” meanwhile, the recent topics of research were heart failure, metabolism, comorbidity, Ethiopia, muscle, cardiovascular event and drug user. Conclusion: The reason why USA was found to be one of the key actors in the network is supposed to be the financial resources it can allocate for the studies conducted. It appears that the majority of the studies in the field dwell upon the impact of exercise on the physical parameters in HIV patients, whereas there are only a limited number of studies focusing on the impact of exercise on HIV-induced psychological and cognitive problems. Recent studies on neurocognitive impairment, on the other hand, are predictive of possible future popularity of such topics among researchers.

The Impact

Introduction: In the United States, over 1,000,000 total joint arthroplasty (TJA) surgeries are performed annually and has been forecasted that this number will exceed 4,000,000 by the year 2030. Many different types of dressing exist for use in TJA surgery, and it is unclear if any of the newer, hydrofibre dressings are superior to traditional dressings at reducing rates of infections or improving wound healing. Thus, the aim of this systematic review and meta-analysis was to assess the impact of hydrofiber dressings on reducing complications. Methods: A systematic review and meta-analysis was performed using the online databases MEDLINE and the Cochrane Library. Randomized controlled trials (RCTs) comparing hydrofibre dressings to a standard dressing were included. Summary measures are reported as odds ratios (ORs) and mean differences (MDs) with 95% confidence intervals (CIs). Our primary outcome was prosthetic joint infection (PJI). Secondary outcomes included blisters, dressing changes and wound irritation. Results: 5 RCTs were included. Hydrofibre dressing had no observable effect on PJI or wound irritation (OR 0.53; 95% CI, 0.14–1.98; p = 0.35). Hydrofibre dressings reduced the rate of blisters (OR 0.36; 95% CI, 0.14–0.90; p = 0.03) and number of dressing changes (MD -1.89; 95% CI, -2.68 to -1.11). Conclusions: In conclusion, evidence suggests hydrofibre dressings have no observable effect on PJI and wound irritation. Evidence for reduction in blisters and number of dressings is modest given wide CIs and biased trial methodologies. Use of hydrofibre dressings should be considered inconclusive for mitigating major complications in light of current best evidence.

Abstract Background Understanding the true magnitude of infant respiratory syncytial virus (RSV) burden is critical for determining the potential public-health benefit of RSV prevention strategies. Although global reviews of infant RSV burden exist, none have summarized data from the United States or evaluated how RSV burden estimates are influenced by variations in study design. Methods We performed a systematic literature review and meta-analysis of studies describing RSV-associated hospitalization rates among US infants. We also examined the impact of key study characteristics on these estimates. Results After review of 3058 articles through January 2020, we identified 25 studies with 31 unique estimates of RSV-associated hospitalization rates. Among US infants < 1 year of age, annual rates ranged from 8.4 to 40.8 per 1000 with a pooled rate= 19.4 (95%CI= 17.9–20.9). Study type was associated with RSV hospitalization rates (P =.003), with active surveillance studies having pooled rates per 1000 (11.1; 95%CI: 9.8–12.3) that were half that of studies based on administrative claims (21.4; 95%CI: 19.5–23.3) or modeling approaches (23.2; 95%CI: 20.2–26.2). Conclusion Applying the pooled rates identified in our review to the 2020 US birth cohort suggests that 73,680 to 86,020 RSV-associated infant hospitalizations occur each year. To date, public-health officials have used conservative estimates from active surveillance as the basis for defining US infant RSV burden. The full range of RSV-associated hospitalization rates identified in our review better characterizes the true RSV burden in infants and can better inform future evaluations of RSV prevention strategies.

The Impact

Sexual assault and case attrition at the arrest stage are serious problems in the United States. Focal concerns have increasingly been used to explain police decision making in sexual assault cases. Because of the popularity of the focal concerns perspective and potential to inform evidence-based training, a systematic review and meta-analysis are needed to condense the literature. In this study, we assess the overall strength of the relationship between focal concerns variables and police decisions to arrest in cases of sexual assault. Our assessment of the effects of focal concerns variables on arrest decision making in sexual assault cases followed the systematic review protocols provided by the Campbell Collaboration of Systematic Reviews. Specifically, we used the Campbell Collaboration recommendations to search empirical literature and used meta-analysis to evaluate the size, direction, and strength of the impact of focal concerns variables on arrest decisions. Our search strategy detected 14 eligible studies and 79 effect sizes. The meta-analysis found several robust and statistically significant correlates of arrest. In fact, each focal concerns concept produced at least one robust arrest correlate. Overall, focal concerns offers a strong approach for explaining police decisions in sexual assault cases. Although practical concerns and resource constraints produced the strongest arrest correlates, results show the importance of additional case characteristics in officers’ decision to arrest.

The impact of market share on financial firm performance is one of the most widely studied relationships in marketing strategy research. However, since the meta-analysis by Szymanski, Bharadwaj, and Varadarajan (1993) , substantial environmental (e.g., digitization) and methodological (e.g., accounting for endogeneity) developments have occurred. The current work presents an updated and extended meta-analysis based on all available 863 elasticities drawn from 89 studies and provides the following new empirical generalizations: (1) The average raw market share–financial performance elasticity is .132, which is substantially lower than the effectiveness of other intermediate marketing metrics. This result challenges a widely used strategy that solely focuses on increasing market share. (2) Elasticities differ significantly between contextual settings. For example, they are lower for business-to-business firms than for business-to-consumer firms, for service firms than for manufacturing firms, and for U.S. markets than for emerging and Western European markets. The authors also observe differences between countries with respect to a general time trend (e.g., lower elasticities in recent times for Western European markets) and recessionary periods (e.g., lower elasticities in the United States, higher elasticities in non-Western economies).

Abstract This systematic review and meta-analysis aimed to evaluate the impact of COVID-19 on pregnant women. We searched for qualified studies in PubMed, Embase, and Web of Science. The clinical characteristics of pregnant women with COVID-19 and their infants were reported as means and proportions with 95% confidence interval. Eleven studies involving with 9032 pregnant women with COVID-19 and 338 infants were included in the meta-analysis. Pregnant women with COVID-19 have relatively mild symptoms. However, abnormal proportions of laboratory parameters were similar or even increased, compared to general population. Around 30% of pregnant women with COVID-19 experienced preterm delivery, whereas the mean birth weight was 2855.9 g. Fetal death and detection of SARS-CoV-2 were observed in about 2%, whereas neonatal death was found to be 0.4%. In conclusion, the current review will serve as an ideal basis for future considerations in the treatment and management of COVID-19 in pregnant women.

Background. The keratorefractive surgeries (KRS) are one of the most common ocular surgeries. One of the dangerous complications of these surgeries is infectious keratitis (IK), which is the second cause of blindness after cataract surgery. The purpose of this study was to estimate the prevalence of IK after KRS in different parts of the world. Methods. In order to obtain relevant studies, all national and international databases including IranMedex, SID, Magiran, IranDoc, Medlib, ScienceDirect, PubMed, Scopus, Cochrane, Embase, Web of Science, and Google Scholar were searched using standard keywords. Results. IK prevalence after KRS was 0.000496% (0.000145% for the left eye and 0.000149% for the right eye). IK prevalence after KRS in the United States, Europe, and Asia was 0.000667%, 0.000473%, and 0.000045%, respectively, in all of which the common microorganisms were Staphylococci. Meta-regression showed no significant association between IK after KRS and either sample size or publication year of the studies. IK prevalence after KRS in the right eye was more than that in the left one. Also, the probability of IK incidence after LASIK surgery was more than PRK and LASEK. In the evaluation of continents, IK after KRS in the United States was more frequent compared with Europe and Asia. Conclusions. This study provided data as to the overall prevalence of IK following KRS and its variations according to the types of eye, surgery, pathogenic microorganism, and geographical location.

Abstract Background and Objectives The application of mindfulness- and acceptance-based interventions (MABIs) for informal caregivers of people with dementia (PwD) is relatively novel, and the current state of the evidence base is unclear. This meta-analysis examined the effectiveness of MABIs on reducing symptoms of depression and burden in informal caregivers of PwD. The quality of included studies was evaluated and moderator variables explored. Research Design and Methods A literature search of six electronic databases (PsycARTICLES, PsycINFO, MEDLINE Complete, SCOPUS, Web of Science, and ProQuest) was conducted from the first available date to 20 December 2016. Inclusion criteria involved studies that quantitatively investigated the impact of MABIs on depression and/or burden in informal caregivers of PwD. Results Twelve studies, providing data on 321 caregivers, were included. Most used mindfulness-based stress reduction and were conducted in the United States. The average attrition among participants was 15.83%. The pre–post effect of MABIs was large for depression and moderate for burden. These effects were largely maintained at follow-up. Significant heterogeneity of effect sizes was observed, with no significant moderators identified. Study quality varied from very poor to moderately good. Discussion and Implications The low attrition and moderate to large effects suggest that MABIs are acceptable and beneficial for informal caregivers of PwD. The lack of significant moderators could advocate services using more cost-effective forms of MABIs. Further higher-quality research is needed to improve the robustness of the evidence base and enable a meta-analysis to thoroughly examine and quantify moderator variables.

ABSTRACT. Sport psychology research and the specific journals scenario. Background: There is a remarkable growth in the production of knowledge in the field of sports psychology (SP). The knowledge produced by researchers occurs through the publication of their work in the format of articles in scientific journals. There are no analyses in the literature considering the specific journals of the area and their characteristics. Objective: To discuss about the current scenario of specific journals related to SP. Methods: This is a documentary research about the SP journals. The following data were extracted and analyzed: country, institution, publisher, publication language, metrics (JCR - ISI Web of Science, SJR, Citescore and SNIP – Scopus, and index h5 – Google Scholar), periodicity, publication period, and number of articles published in 2018. Results: It was observed 14 journals related to SP. Most of them are from United States, three from Spain and three from United Kingdom. Brazil, Italy and Netherlands showed one journal each. Most of the journals publish in English language (13 of 14). The impact factor ranged from 0.64 to 6.90, and five journals do not show this metric in 2018. In this year, the journals published from 11 to 144 articles. Conclusion: From the analysis of the specific scientific journals of the SP, it was found that the journals with highest quality are from the United States and Europe. In Brazil, there is a need to strengthen the existing specific journal in the area, which can be done by unifying the organizations that work in professional practice and scientific research of SP.

Background: There is a growing trend toward verification of trauma centres, but its impact remains unclear. This systematic review aimed to synthesize available evidence on the effectiveness of trauma centre verification. Methods: We conducted a systematic search of the CINAHL, Embase, HealthStar, MEDLINE and ProQuest databases, as well as the websites of key injury organizations for grey literature, from inception to June 2019, without language restrictions. Our population consisted of injured patients treated at trauma centres. The intervention was trauma centre verification. Comparison groups comprised nonverified trauma centres, or the same centre before it was first verified or re-verified. The primary outcome was in-hospital mortality; secondary outcomes included adverse events, resource use and processes of care. We computed pooled summary estimates using random-effects meta-analysis. Results: Of 5125 citations identified, 29, all conducted in the United States, satisfied our inclusion criteria. Mortality was the most frequently investigated outcome (n = 20), followed by processes of care (n = 12), resource use (n = 12) and adverse events (n = 7). The risk of bias was serious to critical in 22 studies. We observed an imprecise association between verification and decreased mortality (relative risk 0.74, 95% confidence interval 0.52 to 1.06) in severely injured patients. Conclusion: Our review showed mixed and inconsistent associations between verification and processes of care or patient outcomes. The validity of the published literature is limited by the lack of robust controls, as well as any evidence from outside the US, which precludes extrapolation to other health care jurisdictions. Quasiexperimental studies are needed to assess the impact of trauma centre verification. Systematic reviews registration: PROSPERO no. CRD42018107083

Chitosan is a renewable natural alkaline polysaccharide, and laponite is a multifunctional nanocomposite. Their use exists in several areas, mainly due to their non-toxicity and because chitosan is from natural resources. One primary use in seed coating processes consists of applying an exogenous material to the seeds, which can facilitate handling and planting. Thus, this study aimed to investigate the most appropriate uses in patented and publications related to the use of Laponite and Chitosan to access these materials' state of the art to identify perspectives for new research. One hundred two publications were explored in the scientific databases Scopus (53) and Web of Science (WoS) (79). Of these, duplicates were removed, totaling 93 articles with publications started in 2006. The number of publications on chitosan and laponite for the countries with the highest number of corresponding authors was from China (27), Iran (16), and the United States (15). Brazil also stands out and occupies the fourth position regarding the number of corresponding authors (7). There were prospected 109 patents, and most of them have been used in medical or veterinary hygiene, or hygienic devices and methods (A61K), in cosmetics (A61Q). The compilation and analysis of scientific, technological, and information use carried out in this work has allowed for identifying the new research perspectives and validated the potential use of chitosan and laponite association as a seed coating.
