<b><i>Background:</i></b> Angiogenesis in non-Hodgkin lymphoma (NHL) has been investigated by a variety of studies. However, the correlation between angiogenesis and the occurrence or prognosis of NHL patients remains controversial. <b><i>Methods:</i></b> We performed a systematic and comprehensive retrieval of relevant literatures from PubMed, EMBASE, and Web of Science databases. The quality of the eligible studies was assessed using the Newcastle-Ottawa Scale (NOS). <b><i>Results:</i></b> Fifteen eligible studies containing a total of 1373 NHL patients were included in this study. All the eligible studies were high-quality studies scoring ≥6 points. MVD was not different between NHL and control (SMD = 0.281, 95% CI: −1.410 to 1.972, <i>p</i> = 0.745). High MVD was associated with advanced disease stage (OR = 1.580, 95% CI: 1.080–2.311, <i>p</i> = 0.018) and unfavorable OS (HR = 1.656, 95% CI: 1.366–2.009, <i>p</i> = 0.000) but not with PFS (HR = 1.349, 95% CI: 0.852–2.136, <i>p</i> = 0.201). <b><i>Conclusion:</i></b> This meta-analysis demonstrated that high MVD was related to advanced disease stage and associated with unfavorable OS of NHL patients.

AbstractThe incidence of non-Hodgkin lymphoma (NHL) has increased steadily for the past few decades. Previous studies have suggested an association between blood transfusions and NHL. The main objective of this study was to evaluate this relationship with a meta-analysis of observational studies. A literature search was undertaken, looking for case-control and cohort studies evaluating the risk of developing NHL in persons who received allogeneic blood transfusions; 14 studies were included. Outcome was calculated and reported as relative risk (RR). Heterogeneity was assessed with Cochrane Q and I2 statistics. Dissemination bias was evaluated by funnel plot visualization and trim-and-fill analysis. Quality assessment was performed with the Newcastle-Ottawa scale. Our analysis showed a RR of developing NHL of 1.05 (95% CI, 0.89-1.25; P = .42) and 1.34 (95% CI, 1.15-1.55; P < .01) in case-control and cohort studies, respectively. When pooling all studies, RR was 1.2 (95% CI, 1.07-1.35; P < .01). In subset analysis, RR of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) was 1.66 (95% CI, 1.08-2.56; P = .02). The RR of NHL was elevated in both men and women and in persons receiving transfusions either before or after 1992. Blood transfusions appear to increase the risk of developing NHL; however, the risk of CLL/SLL appears higher than for other NHL subtypes.

Purpose: Sarcopenia is a major disease affecting mortality and quality of life in the elderly population. We performed a meta-analysis of studies on the community-dwelling population to investigate the prevalence of sarcopenia and its association with diabetes.Methods: Databases were searched for studies published up to February 3, 2021, reporting the prevalence of sarcopenia in patients with and without diabetes. Data extraction and quality assessment were performed according to the Newcastle-Ottawa scale.Results: Six articles were included in the systematic review. All the patients were Asian, aged ≥60 years (women 53.4%), and the diabetic and non-diabetic population was 1,537 and 5,485, respectively. In all six studies, the Asian Working Group for Sarcopenia criteria were used to diagnose sarcopenia. The prevalence of sarcopenia was 15.9% in diabetics and 10.8% in non-diabetics. Diabetics showed a significantly higher risk of sarcopenia than non-diabetics (pooled OR = 1.518, 95% CI = 1.110 to 2.076, Z-value = 2.611, p = 0.009).Conclusion: Among the Asian community-dwelling geriatric population, the prevalence of sarcopenia was significantly higher in diabetics than in non-diabetics. These results suggest that strategies for the management of sarcopenia are required in Asian elderly patients, especially with diabetes.

AbstractBackgroundThis systematic review and meta-analysis was aimed to evaluate the efficacy and safety of tocilizumab (TCZ) in treating severe coronavirus disease 2019 (COVID-19).MethodsThe electronic search was performed using PubMed, Scopus, CENTRAL, and Google scholar to identify the retrospective observational reports. The studies published from 01 January 2020 to 30th September 2020. Participants were hospitalized COVID-19 patients. Interventions included tocilizumab versus placebo/standard of care. The comparison will be between TCZ versus standard of care (SOC)/placebo. Inconsistency between the studies was evaluated with I2 and quality of the evidences were evaluated by Newcastle-Ottawa scale.ResultsBased on the inclusion criteria there were 24 retrospective studies involving 5686 subjects were included. The outcomes of the meta-analysis have revealed that the TCZ has reduced the mortality (M-H,RE-OR −0.11(−0.18 to −0.04) 95% CI, p =0.001, I2 =88%) and increased the incidences of super-infections (M-H, RE-OR 1.49(1.13 to 1.96) 95% CI, p=0.004, I2=47%). However, there is no significant difference in ICU admissions rate (M-H, RE-OR −0.06(−0.23 to 0.12), I2=93%), need of MV (M-H, RE-OR of 0.00(−0.06 to 0.07), I = 74%), LOS (IV −2.86(−0.91 to 3.38), I2=100%), LOS-ICU (IV: −3.93(−12.35 to 4.48), I2=100%), and incidences of pulmonary thrombosis (M-H, RE-OR 1.01 (0.45 to 2.26), I2=0%) compared to SOC/control.ConclusionBased on cumulative low to moderate certainty evidence shows that TCZ could reduce the risk of mortality in hospitalized patients. However, there is no statistically significant difference observed between the TCZ and SOC/control groups in other parameters.

Background and objectives: The association between hypnotic drugs and risk of cancer remains controversial. Therefore, we performed a meta-analysis to investigate this association. Materials and Methods: Pubmed and Embase were searched systematically to identify publications up to April 2020. The Newcastle-Ottawa scale for observational studies was used to assess the quality of studies. All included studies were evaluated by two reviewers independently; any discrepancies were resolved through discussion. Results: Twenty-eight studies including 22 case-control studies and 6 cohort studies with 340,614 hypnotics users and 1,828,057 non-users were included in the final analyses. Hypnotics (benzodiazepines and Z-drugs) use was significantly associated with an increased risk of cancer (odds ratio [OR] or relative risk [RR] 1.17; 95% confidence interval 1.09–1.26) in a random-effects meta-analysis of all studies. Subgroup meta-analysis by anxiolytics/sedatives effect (anxiolytics benzodiazepines vs. sedatives group (include sedatives benzodiazepines and Z-drugs)) revealed that a significant association in sedatives group (pooled OR/RR 1.26, 95% CI, 1.10–1.45), whereas no significant relationship was observed in anxiolytics benzodiazepines (pooled OR/RR 1.09, 95% CI, 0.95–1.26). Moreover, a significant dose–response relationship was observed between the use of hypnotics and the risk of cancer. Conclusions: This meta-analysis revealed association between use of hypnotics drugs and risk of cancer. However, the use of lower dose hypnotics and shorter duration exposed to hypnotics seemed to be not associated with an increased risk of cancer. Moreover, the use of anxiolytics effect benzodiazepines seemed to be lower risk than sedatives benzodiazepines. A high heterogeneity was observed among identified studies, and results were inconsistent in some subgroups. Randomized control trials are needed to confirm the findings in the future.

Background: There is no effective therapy for COVID-19. Hydroxychloroquine (HCQ) and chloroquine (CQ) have been used for its treatment but their safety and efficacy remain uncertain. Objective: We performed a systematic review to synthesize the available data on the efficacy and safety of CQ and HCQ for the treatment of COVID-19. Methods: Two reviewers searched for published and pre-published relevant articles between December 2019 to 8th June 2020. The data from the selected studies were abstracted and analyzed for efficacy and safety outcomes. Critical appraisal of the evidence was done by Cochrane risk of bias tool and Newcastle Ottawa scale. The quality of evidence was graded as per the GRADE approach. Results: We reviewed 12 observational and 3 randomized trials which included 10659 patients of whom 5713 received CQ/HCQ and 4966 received only standard of care. The efficacy of CQ/HCQ for COVID-19 was inconsistent across the studies. Meta-analysis of included studies revealed no significant reduction in mortality with HCQ use [RR 0.98 95% CI 0.66-1.46] , time to fever resolution [mean difference -0.54 days (-1.19-011)] or clinical deterioration/development of ARDS with HCQ [RR 0.90 95% CI 0.47-1.71]. There was a higher risk of ECG abnormalities/arrhythmia with HCQ/CQ [RR 1.46 95% CI 1.04 to 2.06]. The quality of evidence was graded as very low for these outcomes. Conclusions: The available evidence suggests that CQ or HCQ does not improve clinical outcomes in COVID-19. Well-designed randomized trials are required for assessing the efficacy and safety of HCQ and CQ for COVID-19.

<b><i>Introduction:</i></b> The aim of this study is to investigate the association between loss of muscle mass and prognosis of sepsis. <b><i>Methods:</i></b> Six databases, including PubMed, Embase, Cochrane Library, Web of Science, Scopus, and Ovid, were searched by the deadline of August 18, 2020. A meta-analysis was conducted on the collected data by means of a random-effects model. The quality of each included article was assessed according to the Newcastle-Ottawa Scale. <b><i>Results:</i></b> Out of 1,819 references, 6 articles and 1 conference abstract were included. Sepsis patients with a loss of muscle mass or sarcopenia had higher mortality (risk ratio [RR]: 1.94, 95% confidence intervals [CI]: 1.59–2.37; I-squared = 18.7%, <i>p</i> &#x3c; 0.001). The RR of mortality within 30 days (RR: 2.31, 95% CI: 1.78–2.99, <i>p</i> &#x3c; 0.001) was higher than that of mortality over 30 days. Loss of psoas muscle mass, as evaluated by CT, showed the highest RR of sepsis mortality. In addition, based on data on overall survival retrieved from 4 trials, the pooled hazard ratio (HR) for patients with a loss of muscle mass or sarcopenia was 3.04. Subgroup analysis showed that survival time was the main source of heterogeneity for the overall HR. Furthermore, the scanning areas of muscle mass in survival patients were 0.33 cm<sup>2</sup>/m<sup>2</sup> higher than those measured in deceased patients. <b><i>Conclusion:</i></b> A loss of muscle mass, as evaluated by CT scan, was associated with a poor outcome in sepsis.

Background: It is critical to understand factors that may contribute to an increased risk of SPTC in order to develop surveillance protocols in high-risk individuals. This systematic review and meta-analysis will assess the association between primary malignancy and SPTC. Methods: A search of PubMed and Embase databases was completed in April 2020. Inclusion criteria included studies that reported the incidence or standardized incidence ratio of any primary malignancy and SPTC, published between 1980–2020. The PRISMA guidelines were followed and the Newcastle–Ottawa Scale was used to assess quality of studies. Results: 40 studies were included, which were comprised of 1,613,945 patients and 15 distinct types of primary cancers. In addition, 4196 (0.26%) patients developed SPTC following a mean duration of 8.07 ± 4.39 years. Greater risk of developing SPTC was found following primary breast (56.6%, 95%CI, 44.3–68.9, p < 0.001), renal cell (12.2%, 95%CI, 7.68–16.8, p < 0.001), basal cell (7.79%, 95%CI, 1.79–13.7, p = 0.011), and ovarian cancer (11.4%, 95%CI, 3.4–19.5, p = 0.005). SPTC patients were more likely to be females (RR = 1.58, 95%CI, 1.2–2.01, p < 0.001) and Caucasians (p < 0.001). Conclusions: Surveillance protocols should be considered for patients at a higher risk of SPTC, including those with primary breast, renal cell, basal cell and ovarian cancers who are female and/or Caucasian.

BACKGROUND: Obesity, common condition among patients with COVID-19, contributes to illness severity during hospitalization. To date, knowledge on the prevalence, risk of hospital and intensive care units (ICU) admissions and mortality is limited. Therefore, systematic review and meta-analysis were conducted using a PRISMA guideline. PURPOSE: The study aimed to address the prevalence, risk of hospital and ICU admissions and mortality among patients with COVID-19 and obesity. METHODS: The Newcastle–Ottawa scale was used to assess the quality of a study. Primary outcomes were the prevalence and risk of hospitalization, and secondary outcomes were the risk of ICU admissions and mortality risk. Mantel–Haenszel with random effects was applied, and the effect measure was odds ratio (OR) with 95% confidence interval (CI). RESULTS: Nine studies were included in the systematic review, and only four studies for meta-analysis. Among 29,776 patients with COVID-19, obesity was identified as the second-highest comorbidity. The prevalence rates of obesity and severe obesity among patients with COVID-19 were 26.1% and 15.5%, respectively. Obesity resulted in significantly increased risk of hospital admission (OR = 1.99, 95% CI = 1.12–3.53, p = 0.02) and ICU admission (OR = 1.77, 95% = CI 1.52–2.06, p < 0.00001). Severe obesity had a significantly increased risk of ICU admission (OR = 1.79, 95% CI = 1.42–2.25, p < 0.00001). The mortality rate of patients with COVID-19 and obesity was about 30.5% (438/1,434), and 19.7% (2,777/14,095) of them recovered from COVID-19. CONCLUSION: Obesity poses as nearly twice the risk of hospital and ICU admissions, and severe obesity contributes to almost twice the risk of ICU admissions.

This study was conducted to determine the prevalence of prolonged neuromuscular symptoms, including fatigue, anosmia, headache, myalgia, and joint pain in COVID-19 survivors hospitalized with mild, moderate, or severe infections worldwide. The search was conducted up to January 30th, 2021 using three databases (PubMed, Scopus, and Web of Science) to identify potentially eligible studies. Data on study characteristics, follow-up characteristics, and severity of COVID-19 during hospitalization were collected in accordance with PRISMA guidelines. The Newcastle-Ottawa scale was used to assess the quality of relevant articles. The estimated prevalence of specific prolonged neuromuscular symptoms and the association between COVID-19 severity and occurrence of prolonged neuromuscular symptoms was analyzed wherever appropriate. Database search yielded 4,050 articles and 22 articles were included for meta-analysis. The estimated prevalence of prolonged fatigue was recorded in 21.2% (95%CI: 11.9%–34.8%) of 3,730 COVID-19 survivors. Persistent anosmia was recorded in 239 of 2,600 COVID-19 survivors (9.7%, 95%CI: 6.1%–15.2%). In 84 out of 2,412 COVID-19 survivors (8.9%, 95%CI: 3.2%–22.6%), prolonged headache was observed. A total of 53 out of 1,125 COVID-19 patients (5.6%, 95%CI: 2.1%–14.2%) complained of persistent myalgia even after being discharged from the hospital. The prevalence of prolonged joint pain was in 15.4% (95%CI: 8.2%–27.2%) of subjects. Due to data scarcity on COVID-19 severity and prolonged neuromuscular symptoms, association analysis could not be conducted. Widespread concern regarding long-term impacts of COVID-19 was raised after several studies reported prolonged symptoms in COVID-19 survivors. Numerous theories have been proposed to address this concern; however, as the research on this pandemic is still ongoing, no explanation is definitive yet. Therefore, follow-up studies in COVID-19 survivors after recovery from COVID-19 are warranted to determine the pathogenesis of prolonged symptoms. PROSPERO registration: CRD42021242332.

By retrieving literature published from 2005 to 2015 from Chinese National Knowledge Infrastructure, Wanfang, Vip, PubMed, and Web of Science, we filtered out studies using the Children’s Depression Inventory only and compared left-behind children and non-left-behind children. The methodological quality of the papers was evaluated using the Newcastle–Ottawa Scale. Finally, we included six studies to carry out a meta-analysis. The results showed that the Children’s Depression Inventory scores of left-behind children are significantly higher than those of non-left-behind children (standardized mean difference: −0.233, 95% confidence interval: −0.036 to −0.430, p < 0.05).
