The impact of chronic rhinosinusitis on COVID-19 risk and outcomes: A systematic review and meta-analysis
BackgroundThe impact of chronic rhinosinusitis (CRS) and subsequent steroid therapy on acquiring COVID-19 and severe outcomes remains controversial. Therefore, we conducted this systematic review and meta-analysis to provide cumulative evidence regarding the risk of COVID-19 and the impact of steroid therapy, length of hospital stay, mechanical ventilation, and mortality among CRC patients.MethodsWe conducted a comprehensive electronic search strategy using the relevant keywords. The outcomes and risk factors of COVID-19 in CRS patients was estimated and compared to a healthy control group when applicable.ResultsA total of seven studies were included, with an estimated prevalence of 6.5% (95% confidence interval (CI): 2.5-15.7) for COVID-19 in the CRS group. COVID-19 prevalence did not differ between CRS and controls (odds ratio (OR): 0.92; 95%CI: 0.84-1.01; p = 0.08). Moreover, using steroid/immunosuppressive therapy did not significantly increase the risk of acquiring COVID-19 in CRS patients compared to the control group (OR: 3.31; 95%CI: 0.72-15.26; p = 0.12). Length of hospital stay, mechanical ventilation, and mortality rates were comparable between the two groups. Furthermore, we found that male sex, cardiovascular morbidity, renal diseases, and hypertension were inversely associated with COVID-19 infection (p < 0.01).ConclusionCRS had a neutral effect on acquiring COVID-19 and developing severe outcomes. However, further studies are needed
Physical activity level and stroke risk in US population: A matched case-control study of 102,578 individuals
Background: Stroke has been linked to a lack of physical activity; however, the extent of the association between inactive lifestyles and stroke risk has yet to be characterized across large populations.
Purpose: This study aimed to explore the association between activity-related behaviors and stroke incidence.
Methods: Data from 1999 to 2018 waves of the concurrent cross-sectional National Health and Nutrition Examination Survey (NHANES) were extracted. We analyzed participants characteristics and outcomes for all participants with data on whether they had a stroke or not and assessed how different forms of physical activity affect the incidence of disease.
Results: Of the 102,578 individuals included, 3851 had a history of stroke. A range of activity-related behaviors was protective against stroke, including engaging in moderate-intensity work over the last 30 days (OR = 0.8, 95% CI = 0.7-0.9; P = 0.001) and vigorous-intensity work activities over the last 30 days (OR = 0.6, 95% CI = 0.5-0.8; P \u3c 0.001), and muscle-strengthening exercises (OR = 0.6, 95% CI = 0.5-0.8; P \u3c 0.001). Conversely, more than 4 h of daily TV, video, or computer use was positively associated with the likelihood of stroke (OR = 11.7, 95% CI = 2.1-219.2; P = 0.022).
Conclusion: Different types, frequencies, and intensities of physical activity were associated with reduced stroke incidence, implying that there is an option for everyone. Daily or every other day activities are more critical in reducing stroke than reducing sedentary behavior duration
Association of anthelmintic treatment with malaria prevalence, incidence, and parasitemia: A systematic review and meta-analysis
A chronic helminth infection can alter host immune response and affect malaria infection. We conducted a systematic review and meta-analysis to find the impact of anthelmintic treatment on malaria prevalence, incidence, and parasitemia. Nine and 12 electronic databases were searched on 28th July 2015 and 26th June 2020 for relevant studies. We performed meta-analysis for malaria prevalence, incidence, parasitemia, and a qualitative synthesis for other effects of anthelmintic treatment. Seventeen relevant papers were included. There was no association between anthelmintic treatment and malaria prevalence or change of parasitemia at the end of follow up period (pooled OR 0.93, 95% CI: 0.62, 1.38, p-value=0.71 and SMD -0.08, 95%CI: -0.24, 0.07, p-value=0.30 respectively) or at any defined time points in analysis. Pooled analysis of three studies demonstrated no association between malaria incidence and anthelmintic treatment (rate ratio 0.93, 95%CI: 0.80, 1.08, p-value=0.33). Our study encourages anthelmintic treatment in countries with high burden of co-infections as anthelmintic treatment is not associated with change in malaria prevalence, incidence, or parasitemia
Abstract Number: LBA6 Mechanical Thrombectomy for Basilar Artery Occlusion: Systematic Review and Metaâanalysis of Randomized Controlled Trials
Introduction Acute ischemic stroke (AIS) caused by basilar artery occlusion (BAO) is known to be associated with high rates of mortality and lifelong disability. In the past few years, two clinical trials (the BEST and the BASICS trials) investigated the benefits and safety of mechanical thrombectomy (MT) for BAO and did not provide evidence to support the efficacy of MT in BAO patients. Given the recent positive results from the ATTENTION and the BAOCHE clinical trials, we conducted this metaâanalysis to provide updated collective evidence regarding the benefits of MT in patients with BAO. Methods We searched for eligible papers till June 1st, 2021, in five databases: PubMed, Web of Science, Scopus, and Embase databases using keywords and/or medical subject (MeSH) terms. We included all randomized controlled trials (RCTs) with no restrictions on publication date, data, or language of the included studies to avoid missing any relevant papers. All data were analyzed using R software. We computed the pooled risk ratios (RRs) and their corresponding 95% confidence intervals (CI), using a randomâeffect model or fixedâeffect model depending on heterogeneity among the included studies. Heterogeneity was assessed with Q statistics and the I2 test considering it significant with I2 value > 50% or Pâvalue < 0.05. Results Four trials were included in this metaâanalysis, namely the BEST, the BASICS, the BAOCHE, and the ATTENTION trials. The four trials recruited a total of 988 patients. The MT group achieved a significantly higher rate of modified Rankin scale (mRS) score of 0â3 was as compared to the best medical treatment (BMT) one (RR = 1.54; 95% CI = 1.16â2.04; Pâvalue = 0.002). Similarly, the mRS 0â2 rate was significantly higher in the MT group as compared to the BMT group (RR = 1.79; 95% CI = 1.09â2.95; Pâvalue = 0.022). Nevertheless, heterogeneity was noticed amongst the included studies. Moreover, there was a significant reduction in the 90âday mortality in the MT group as compared to the BMT group (RR = 0.76; 95% CI = 0.65â0.89; Pâvalue = 0.002). On the other hand, there was a significantly higher rate of symptomatic intracerebral hemorrhage (sICH) in the MT group compared to the BMT group (RR = 7.48; 95% CI = 2.27â24.61; Pâvalue< 0.001). There with no heterogeneity observed in both outcomes of mortality and sICH. Noted that there were no significant differences in overall parenchymal hemorrhage (PH) and type I PH rates, yet type II PH was more prevalent in the MT group compared to the BMT one (RR = 5.53; 95% CI = 1.47â20.84; Pâvalue = 0.011). Conclusions The current evidence favors MT for basilar artery occlusions over the conservative approach in terms of achieving higher rates of good functional outcomes and decreasing mortality rates. Further largeâscale trials of different populations are needed to corroborate these results and also to ensure generalizability

Cardiovascular mortality trends in non-Hodgkinâs lymphoma: a population-based cohort study
<p><b>Background</b>: Non-Hodgkinâs lymphoma (NHL) survivors are at a higher risk of cardiovascular diseases (CVDs).</p> <p><b>Methods</b>: A population-based study was conducted to investigate the cardiovascular mortality trends to identify NHL survivors at the highest risk.</p> <p><b>Results</b>: The CVDs mortality was the second most common cause of death (13.07%) after NHL. There were more patients â„ 60Â years old in the cardiovascular group (87.2%), PÂ <Â 0.001. Patients who died from CVDs had the best survival while patients who died from NHL had a significantly lower mean survival. The overall survival rate was 92.4%. Consistently, older age, unmarried, male patients, not recently diagnosed with NHL and not receiving radiation and/or surgery were associated with a worse survival across all models. The black race and stage IV only had a worse cardiovascular specific survival (CVSS).</p> <p><b>Conclusions</b>: Although the CVSS improved over time, the mortality from the CVDs is still the second most common cause of death after NHL. Older age, not married, black, male patients, not recently diagnosed with NHL, with an advanced stage and not receiving radiation and/or surgery were associated with a worse survival. Risk factor modification along with CVDs screening should be intensified in NHL patients with these mortality predictors.</p
Association between radiotherapy and obstructive sleep apnea in head and neck cancer patients: A systematic review and meta-analysis
Objective: Our aim was to investigate association between OSA and radiotherapy in head and neck cancer patients. Methods: On 9th of September 2018, we have searched 12 electronic databases to retrieve relevant studies. All eligible studies that assessed association between OSA and radiotherapy in head and neck cancer patients were included in our meta-analysis. Quality assessment of included studies was done using the NIH tools for cohort, cross-sectional and case series studies. Results: Fourteen studies met our study selection criteria, and six studies were eligible for our meta-analysis. There was no significant association between occurrence of OSA and radiotherapy in head and neck cancer patients (Odds ratio 1.54, 95% CI [0.66â3.60]; P = 0.322). Conclusion: These findings point to no significant association between OSA risk and radiotherapy in head and neck cancer patients. We suggest more studies to be conducted to investigate any confounders that may influence the effect of radiotherapy on development of OSA in head and neck cancer patients.Auris Nasus Larynx, 48(6), pp.1126-1134; 202
Association of anthelmintic treatment with malaria prevalence, incidence, and parasitemia: A systematic review and meta-analysis
Association between pet ownership and cardiovascular risks and mortality: a systematic review and meta-analysis
The aim of the study was to determine the association between pet ownership and cardiovascular risk factors and mortality. Electronic search was conducted through nine databases including PubMed for relevant publications reporting cardiovascular events and mortality among pet owners. Meta-analysis was used to pool the results. Of a total of 2818 reports screened, 26 studies were included in our systematic review and meta-analysis. Higher survival rate was observed in the pet owners group after pooling nonadjusted and adjusted hazard ratios for cardiovascular mortality at 0.73 [95% confidence interval (CI) 0.62â0.86] and 0.81 (0.68â0.97), respectively. A similar trend was observed for the pooled nonadjusted hazard ratio for overall mortality 0.73 (0.62â0.87) but not the adjusted hazard ratio 0.40 (0.04â3.78). Cat owners have a reduction in cardiovascular mortality but not overall mortality after pooling the adjusted hazard ratio 0.79 (0.63â0.99) and 1.04 (0.90â1.21), respectively. However, no significant association between dog owners and survival rate was observed for overall and cardiovascular-specific mortality. Pet owners had significantly lower heart rate (mean difference 95% CI: â2.32 (â3.07 to â1.57), mean arterial pressure â2.60 (â4.25 to â0.95) and SBP â1.69 (â3.06 to â0.31) but not DBP â0.23 (â1.05 to 0.60). No significant difference was observed between pet owners and nonpet owners in prevalence of hypertension. Our study draws attention to the beneficial effects of the human--pet bond; therefore, we recommend pet acquisition for better cardiovascular outcomes after controlling for zoonotics and pet-induced allergies
