Meta-Analysis
BACKGROUND
Modified FOLFIRINOX and gemcitabine plus nab-paclitaxel (GEM-NAB) have been recommended as first-line therapies for advanced pancreatic cancer (PC). Due to the lack of evidence to directly compare them, we conducted this network meta-analysis to indirectly compare the effectiveness and toxicity of modified FOLFIRINOX and GEM-NAB.
METHODS
The eligible retrospective studies on treatments related to modified FOLFIRINOX and GEM-NAB up to 4 April 2020 were searched and assessed. We used the frequentist model to analyze the survival and toxicity data between different treatments. Pooled analysis for overall survival (OS), progression-free survival (PFS), objective response rate (ORR) and events of toxicity were analyzed in this study.
RESULTS
Twenty-two studies were involved in this network meta-analysis. The comparisons on OS and PFS showed that modified FOLFIRINOX and GEM-NAB had similar treatment efficacy (OS: 1.13; 95% CI: 0.78-1.63; PFS: HR: 1.19; 95% CI: 0.85-1.67). GEM-NAB was more effective than modified FOLFIRINOX based on the result of ORR (RR: 1.43; 95% CI: 1.04-1.96). Moreover, our analysis showed a similar toxicity profile between modified FOLFIRINOX and GEM-NAB.
CONCLUSIONS
The current evidence showed that modified FOLFIRINOX and GEM-NAB were similar in survival and toxicity. Many factors should be considered for in the formulation of optimal treatment, and our meta-analysis could provide some guidance to treatment selection in the first-line setting for advanced PC.

Review
Despite aggressive efforts on containment measures for the coronavirus disease 2019 (COVID-19) pandemic around the world, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is continuously spreading. Therefore, there is an urgent need for an effective antiviral agent. To date, considerable research has been conducted to develop different approaches to COVID-19 therapy. In addition to early observational studies, which could be limited by study design, small sample size, non-randomized design, or different timings of treatment, an increasing number of randomized controlled trials (RCTs) investigating the clinical efficacy and safety of antiviral agents are being carried out. This study reviews the updated findings of RCTs regarding the clinical efficacy of eight antiviral agents against COVID-19, including remdesivir, lopinavir/ritonavir, favipiravir, sofosbuvir/daclatasvir, sofosbuvir/ledipasvir, baloxavir, umifenovir, darunavir/cobicistat, and their combinations. Treatment with remdesivir could accelerate clinical improvement; however, it lacked additional survival benefits. Moreover, 5-day regimen of remdesivir might show adequate effectiveness in patients with mild to moderate COVID-19. Favipiravir was only marginally effective regarding clinical improvement and virological assessment based on the results of small RCTs. The present evidence suggests that sofosbuvir/daclatasvir may improve survival and clinical outcomes in patients with COVID-19. However, the sample sizes for analysis were relatively small, and all studies were exclusively conducted in Iran. Further larger RCTs in other countries are warranted to support these findings. In contrast, the present findings of limited RCTs did not indicate the use of lopinavir/ritonavir, sofosbuvir/ledipasvir, baloxavir, umifenovir, and darunavir/cobicistat in the treatment of patients hospitalized for COVID-19.

Meta-Analysis
BACKGROUND
It remains unclear whether people with non-muscle invasive bladder cancer (NMIBC) benefit from intravesical gemcitabine compared to other agents in the primary or recurrent setting following transurethral resection of a bladder tumor. This is an update of a Cochrane Review first published in 2012. Since that time, several randomized controlled trials (RCTs) have been reported, making this update relevant. OBJECTIVES: To assess the comparative effectiveness and toxicity of intravesical gemcitabine instillation for NMIBC.
SEARCH METHODS
We performed a comprehensive literature search of the Cochrane Library, MEDLINE, Embase, four other databases, trial registries, and conference proceedings to 11 September 2020, with no restrictions on the language or status of publication.
SELECTION CRITERIA
We included RCTs in which participants received intravesical gemcitabine for primary or recurrent NMIBC.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed the included studies and extracted data for the primary outcomes: time to recurrence, time to progression, grade III to V adverse events determined by the Common Terminology Criteria for Adverse Events version 5.0 (CTCAE v5.0), and the secondary outcomes: time to death from bladder cancer, time to death from any cause, grade I or II adverse events determined by the CTCAE v5.0 and disease-specific quality of life. We performed statistical analyses using a random-effects model and rated the certainty of the evidence using GRADE.
MAIN RESULTS
We included seven studies with 1222 participants with NMIBC across five comparisons. This abstract focuses on the primary outcomes of the three most clinically relevant comparisons. 1. Gemcitabine versus saline: based on two years' to four years' follow-up, gemcitabine may reduce the risk of recurrence over time compared to saline (39% versus 47% recurrence rate, hazard ratio [HR] 0.77, 95% confidence interval [CI] 0.54 to 1.09; studies = 2, participants = 734; I = 49%; low-certainty evidence), but the CI included the possibility of no effect. Gemcitabine may result in little to no difference in the risk of progression over time compared to saline (4.6% versus 4.8% progression rate, HR 0.96, 95% CI 0.19 to 4.71; studies = 2, participants = 654; I = 53%; low-certainty evidence). Gemcitabine may result in little to no difference in the CTCAE grade III to V adverse events compared to saline (5.9% versus 4.7% adverse events rate, risk ratio [RR] 1.26, 95% CI 0.58 to 2.75; studies = 2, participants = 668; I = 24%; low-certainty evidence). 2. Gemcitabine versus mitomycin: based on three years' follow-up (studies = 1, participants = 109), gemcitabine may reduce the risk of recurrence over time compared to mitomycin (17% versus 40% recurrence rate, HR 0.36, 95% CI 0.19 to 0.69; low-certainty evidence). Gemcitabine may reduce the risk of progression over time compared to mitomycin (11% versus 18% progression rate, HR 0.57, 95% CI 0.32 to 1.01; low-certainty evidence), but the CI included the possibility of no effect. We are very uncertain about the effect of gemcitabine on the CTCAE grade III to V adverse events compared to mitomycin (RR 0.51, 95% CI 0.13 to 1.93; very low-certainty evidence). The analysis was only based on recurrent NMIBC. 3. Gemcitabine versus Bacillus Calmette-Guérin (BCG) for recurrent (one-course BCG failure) high-risk NMIBC: based on 6 months' to 22 months' follow-up (studies = 1, participants = 80), gemcitabine may reduce the risk of recurrence compared to BCG (41% versus 97% recurrence rate, HR 0.15, 95% CI 0.09 to 0.26; low-certainty evidence) and progression over time (16% versus 33% progression rate, HR 0.45, 95% CI 0.27 to 0.76; low-certainty evidence). We are very uncertain about the effect of gemcitabine on the CTCAE grade III to V adverse events compared to BCG (RR 1.00, 95% CI 0.21 to 4.66; very low-certainty evidence). In addition, the review provides information on the comparison of gemcitabine versus BCG and gemcitabine versus one-third dose BCG. AUTHORS' CONCLUSIONS: Based on findings of this review, gemcitabine may have a more favorable impact on recurrence and progression-free survival than mitomycin but we are very uncertain as to how major adverse events compare. The same is true when comparing gemcitabine to BCG in individuals with high risk disease who have previously failed BCG. The underlying low- to very low-certainty evidence indicates that our confidence in these results is limited; the true effects may be substantially different from these findings; therefore, better quality studies are needed.

5-Aminoimidazole-4-carboxamide ribonucleoside (AICAr) has been one of the most commonly used pharmacological modulators of AMPK activity. The majority of early studies on the role of AMPK, both in the physiological regulation of metabolism and in cancer pathogenesis, were based solely on the use of AICAr as an AMPK-activator. Even with more complex models of AMPK downregulation and knockout being introduced, AICAr remained a regular starting point for many studies focusing on AMPK biology. However, there is an increasing number of studies showing that numerous AICAr effects, previously attributed to AMPK activation, are in fact AMPK-independent. This review aims to give an overview of the present knowledge on AMPK-dependent and AMPK-independent effects of AICAr on metabolism, hypoxia, exercise, nucleotide synthesis, and cancer, calling for caution in the interpretation of AICAr-based studies in the context of understanding AMPK signaling pathway.

BACKGROUND
Uterine leiomyosarcomas are rare malignant mesenchymal tumors. The systemic treatment of these tumors includes chemotherapy and radiotherapy. However, there are still a lot of unanswered questions regarding the ideal therapeutic approach.
METHODS
We have conducted a systematic review of the treatment strategies of uterine leiomyosarcomas for the last ten years.
RESULTS
Adjuvant chemotherapy is still a matter of dilemma. Doxorubicin based chemotherapy or the combination of Gemcitabine-Docetaxel are the regimens of choice for the first line setting. Beyond the first line, there are several options;, including chemotherapy, targeted therapy, and recently efforts of introducing immunotherapy to the therapeutic armamentarium of clinicians treating uterine leiomyosarcomas.
CONCLUSIONS
Despite the efforts of the clinicians dealing with uterine leiomyosarcomas, the optimal therapeutic algorithm is yet to be described.

: Currently, there is no approved therapeutic entity for coronavirus disease 2019 (COVID-19) and clinicians are primarily relying on drug repurposing. However, findings across studies are widely disparate, making it difficult to draw firm conclusions. Since clinicians need accurate evidence to treat COVID-19, this manuscript systematically analyzed the published and ongoing studies evaluating the pharmacological interventions for COVID-19.: A systematic search of observational studies and Clinical Trials on the treatment and prevention of COVID-19 was performed by using various databases from inception to 2 December 2020.: A total of 460 studies met the inclusion criteria. Of these, 37 were research studies, 386 were ongoing trials, and 37 were completed trials. Anti-virals, steroids, anti-malarial, plasma exchange, and monoclonal antibodies were the most common treatment modalities used alone or in combination in these studies. However, tocilizumab, plasma exchange, and steroids have shown significant improvements in patient's clinical and radiological status. Tocilizumab reported minimum hospital stay of 2 days along with maximum recovery and patient's stability rate. Existing literature demonstrate promising results of tocilizumab, plasma exchange, and steroids among COVID-19 patients. Nevertheless, these studies are accompanied by several methodological disparities which should be considered while interpreting the results.

Meta-Analysis
BACKGROUND
This is a updated version of our Cochrane Review published in Issue 6, 2012. Sexually-transmitted infections (STIs) continue to rise worldwide, imposing an enormous morbidity and mortality burden. Effective prevention strategies, including microbicides, are needed to achieve the goals of the World Heath Organization (WHO) global strategy for the prevention and control of these infections.
OBJECTIVES
To determine the effectiveness and safety of topical microbicides for preventing acquisition of STIs, including HIV.
SEARCH METHODS
We undertook a comprehensive search of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, LILACS, CLIB, Web of Science, ClinicalTrials.gov, WHO International Clinical Trials Registry Platform, and reference lists of relevant articles up to August 2020. In addition, we contacted relevant organisations and experts.
SELECTION CRITERIA
We included randomised controlled trials of vaginal microbicides compared to placebo (except for nonoxynol-9 because it is covered in related Cochrane Reviews). Eligible participants were sexually-active non-pregnant, WSM and MSM, who had no laboratory confirmed STIs.
DATA COLLECTION AND ANALYSIS
Two review authors independently screened and selected studies, extracted data, and assessed risks of bias in duplicate, resolving differences by consensus. We conducted a fixed-effect meta-analysis, stratified by type of microbicide, and assessed the certainty of the evidence using the GRADE approach.
MAIN RESULTS
We included eight trials from the earlier version of the review and four new trials, i.e. a total of 12 trials with 32,464 participants (all WSM). We did not find any eligible study that enrolled MSM or reported fungal STI as an outcome. We have no study awaiting assessment. All 12 trials were conducted in sub-Saharan Africa, with one having a study site in the USA, and another having a site in India. Vaginal microbicides tested were BufferGel and PRO 2000 (1 trial, 3101 women), Carraguard (1 trial, 6202 women), cellulose sulphate (2 trials, 3069 women), dapivirine (2 trials, 4588 women), PRO 2000 (1 trial, 9385 women), C31G (SAVVY) (2 trials, 4295 women), and tenofovir (3 trials, 4958 women). All microbicides were compared to placebo and all trials had low risk of bias. Dapivirine probably reduces the risk of acquiring HIV infection: risk ratio (RR) 0.71, (95% confidence interval (CI) 0.57 to 0.89, I = 0%, 2 trials, 4588 women; moderate-certainty evidence). The other microbicides may result in little to no difference in the risk of acquiring HIV (low-certainty evidence); including tenofovir (RR 0.83, 95% CI 0.68 to 1.02, cellulose sulphate (RR 1.20, 95% CI 0.74 to 1.95, BufferGel (RR 1.05, 95% CI 0.73 to 1.52), Carraguard (RR 0.89, 95% CI 0.71 to 1.11), PRO 2000 (RR 0.93, 95% CI 0.77 to 1.14), and SAVVY (RR 1.38, 95% CI 0.79 to 2.41). Existing evidence suggests that cellulose sulphate (RR 0.99, 95% CI 0.37 to 2.62, 1 trial, 1425 women), and PRO 2000 (RR 0.95, 95% CI 0.73 to 1.23) may result in little to no difference in the risk of getting herpes simplex virus type 2 infection (low-certainty evidence). Two studies reported data on tenofovir's effect on this virus. One suggested that tenofovir may reduce the risk (RR 0.55, 95% CI 0.36 to 0.82; 224 participants) while the other did not find evidence of an effect (RR 0.94, 95% CI 0.85 to 1.03; 1003 participants). We have not reported the pooled result because of substantial heterogeneity of effect between the two studies (l = 85%). The evidence also suggests that dapivirine (RR 1.70, 95% CI 0.63 to 4.59), tenofovir (RR 1.27, 95% CI 0.58 to 2.78), cellulose sulphate (RR 0.69, 95% CI 0.26 to 1.81), and (Carraguard (RR 1.07, 95% CI 0.75 to 1.52) may have little or no effect on the risk of acquiring syphilis (low-certainty evidence). In addition, dapivirine (RR 0.97, 95% CI 0.89 to 1.07), tenofovir (RR 0.90, 95% CI 0.71 to 1.13), cellulose sulphate (RR 0.70, 95% CI 0.49 to 0.99), BufferGel (RR 0.97, 95% CI 0.65 to 1.45), Carraguard (RR 0.96, 95% CI 0.83 to 1.12), and PRO 2000 (RR 1.01, 95% CI 0.84 to 1.22) may result in little to no difference in the risk of acquiring chlamydia infection (low-certainty evidence). The evidence also suggests that current topical microbicides may not have an effect on the risk of acquiring gonorrhoea, condyloma acuminatum, trichomoniasis, or human papillomavirus infection (low-certainty evidence). Microbicide use in the 12 trials, compared to placebo, did not lead to any difference in adverse event rates. No study reported on acceptability of the intervention. AUTHORS' CONCLUSIONS: Current evidence shows that vaginal dapivirine microbicide probably reduces HIV acquisition in women who have sex with men. Other types of vaginal microbicides have not shown evidence of an effect on acquisition of STIs, including HIV. Further research should continue on the development and testing of new microbicides.

BACKGROUND
SARS-CoV-2 is a coronavirus that causes a disease which can leads to a severe form of fatal pneumonia. At december 2020 in Italy, more than 2 million people have contracted the virus and 78,755 people have died. The scientific community is studying and testing numerous compounds that can be effective and safe for treating people with covid-19.
AIM
To synthesize and evaluate the quality of evidence of efficacy and safety for the treatment. The available evidence is summarized in a living systematic review, a review that is constantly updated on the basis of the results of the new clinical studies.
METHODS
A bibliographic search is launched weekly on the electronic databases and on the main clinical trial registers. Two researchers independently select the articles and assess the quality of the studies using the criteria developed by the Cochrane Collaboration, the certainty of the overall quality of the evidence is assessed using the GRADE criteria.
RESULTS
At 31/12/2020, 101 randomized controlled studies were included that consider 72 different comparisons and include a total of 55,281 patients. 37 drugs are tested with respect to the standard treatment, 6 are evaluated against placebo and finally 29 compare different drugs with each other. By selecting studies that evaluate the efficacy and safety of a drug compared to standard treatment, which include at least 2 studies and which have low to high certainty of evidence, results show that corticosteroids, remdesivir, favipiravir, immunoglobulins, colchicine, and umbilical cord mesenchymal stem cell infusion could reduce overall mortality. No differences for the risk of any adverse events are observed between convalescent plasma and remdesivir compared to standard treatment. Remdesivir probably reduces the risk of serious adverse events; a similar effect, although less strong, is also noted for tocilizumab and the lopinavir-ritonavir combination. In contrast, hydroxychloroquine, corticosteroids and convalescent plasma transfusion are associated with safety concerns with respect to the risk of serious adverse events.
CONCLUSIONS
The 101 studies included consider 72 comparisons and numerous outcomes, the results often coming from single studies and of small dimensions, and for 61% with a very low certainty of evidence, are difficult to summarize and the final result is to increase the uncertainty rather than providing useful information to the clinic and research. From all the work carried out it seems to us that the pandemic has highlighted the many shadows of scientific literature as tool to improve knowledge.

Review
Alopecia areata is the third most common cause of dermatology consultations in children but the treatment of paediatric alopecia areata remains challenging. A systematic review of the literature about the treatment of alopecia areata in children (≤18 years old) was performed on 11 May 2020 by searching the PubMed, Scopus and EBSCO databases. The terms used for the search were: 'alopecia areata', 'alopecia totalis' or 'alopecia universalis' combined with 'paediatric', 'children' or 'childhood'. A total of 89 articles were included in final evaluation. The most commonly assessed treatment options in paediatric alopecia areata were topical immunotherapy (response rate in monotherapy: 54%; 187/345) intralesional glucocorticosteroids (75%; 211/280), systemic glucocorticosteroids (73%; 102/140), and anthralin (42%; 31/74). Topical glucocorticosteroids (81%; 35/43), systemic Janus kinase (JAK) inhibitors (90%; 27/30), topical calcineurin inhibitors (42%; 8/19), topical JAK inhibitors (65%; 11/17), PUVA therapy (56%; 9/16) and 308-nm excimer laser (77%; 10/13) were also evaluated. Additionally, evaluation in smaller numbers of paediatric patients included methotrexate (100%; 10/10), topical minoxidil (44%; 4/9) and cyclosporine (83%; 5/6). There were limited data considering children with alopecia areata treated with azathioprine, hydroxychloroquine, topical sildenafil, topical prostaglandin analogues, fractional carbon dioxide laser, leflunomide, mesalazine, apremilast, dupilumab, ustekinumab, efalizumab, botulinum toxin, and compound glycyrrhizin. On the basis of the limited data available glucocorticosteroids (systemic, intralesional or topical) and JAK inhibitors (systemic or topical) may be considered the best documented and most effective treatment options in alopecia areata in children. There are no sufficient paediatric data to compare treatment safety and relapse rates in these therapeutic modalities.

Meta-Analysis Review
The use of ibrutinib is hampered by major bleeding events and atrial fibrillation. Speculating whether randomized controlled trials might underestimate the risk of adverse events in clinical practice, we conducted a systematic review and meta-analysis studying patients treated in any setting and indication. We systematically searched the literature using MEDLINE and EMBASE databases for case series, cohort studies, or randomized controlled trials and retrieved all data in parallel. Proportions of patients with adverse events were pooled in relevant subgroups using the binominal distribution and Freeman-Tukey double arcsine transformation. Among 2'537 records screened, 85 were finally included, comprising 7'317 patients. Methodological quality according to the Newcastle-Ottawa Scale was rated as moderate to poor with regard to bleeding events and atrial fibrillation; 106 studies were excluded because of missing data at all. Reported events varied substantially between 0 % and 78 % (any bleedings), 0 % and 25 % (major bleedings), and 0 % and 38 % (new-onset atrial fibrillation). Pooled estimates were 28 % (95 % confidence interval 22 %, 34 %), 3 % (2 %, 4 %), and 8 % respectively (7 %, 10 %). The risk of events was higher in studies with an older population, high ibrutinib dosage, thrombocytopenia, antithrombotic treatment, and retrospective studies. In conclusions, reporting of bleeding events and atrial fibrillation varied substantially among studies. These observations, in combination with the estimates obtained, suggest a relevant risk in clinical practice.
