Meta-Analysis Review
BACKGROUND
Acute hepatitis B infection is associated with severe liver disease and chronic sequelae in some cases. The purpose of this review was to determine the efficacy of nucleoside analogues (NA) (lamivudine versus entecavir) compared to placebo or no intervention for treating acute primary HBV infection.
METHODS
A meta-analysis for drug intervention was performed, following a fixed-effect model. Randomized controlled trials (RCTs) and quasi-randomized studies that evaluated the outcomes of NA in acute hepatitis B infection were included. The following outcomes were considered: virological cure (PCR negative), elimination of acute infection (seroconversion of HBsAg), mortality, and serious adverse events.
RESULTS
Five trials with 627 adult participants with severe acute hepatitis B defined by biochemical and serologic parameters were included. Virological cure did not favor any intervention: OR 0.96, 95% CI 0.54 to 1.7 ( = 0.90), I2 = 58%. Seroconversion of HBsAg to negative favored placebo/standard-of-care compared to lamivudine: OR 0.54, 95% CI 0.33 to 0.9 ( = 0.02), I2 = 31%. The only trial that compared entecavir and lamivudine favored entecavir over lamivudine (OR: 3.64, 95% CI 1.31-10.13; 90 participants). Adverse events were mild.
CONCLUSION
There is insufficient evidence that NA obtain superior efficacy compared with placebo/standard-of-care in patients with acute viral hepatitis, based on low quality evidence.

Review
Pancreatic cancer is the seventh leading cause of cancer deaths worldwide, accounting for 4.7% of all cancer deaths, and is expected to climb significantly over the next decade. The purpose of this systematic review and guidance document was to synthesize the evidence surrounding the role of adjuvant treatment (chemotherapy and chemoradiation therapy [CRT], and stereotactic body radiation therapy [SBRT]) in resected pancreatic ductal adenocarcinoma (PDAC). Systematic literature searches of MEDLINE, EMBASE, and 11 guideline databases were conducted. Both direct and indirect comparisons indicate adjuvant chemotherapy offers a survival advantage over surgery alone. The optimal regimens recommended are mFOLFIRINOX with alternative options of gemcitabine plus capecitabine, gemcitabine alone, or S-1 (which is not available in North America). Trials comparing a CRT strategy to modern chemotherapy regimens are lacking. However, current evidence demonstrates that the addition of CRT to chemotherapy does not result in a survival advantage over chemotherapy alone and is therefore not recommended. Trials evaluating SBRT in PDAC are also lacking. SBRT should only be used within a clinical trial or multi-institutional registry.

Meta-Analysis
OBJECTIVE
To review the evidence concerning treatment-related gynecomastia in patients taking spironolactone, antiandrogens, 5 alpha-reductase inhibitors, lipid-lowering and psychotropic drugs.
MATERIAL AND METHODS
A search of Medline and EMBASE was performed up to 30 June 2021. We included randomized controlled trials comparing the effects of a drug belonging to these classes versus placebo or versus a drug of the same class.
RESULTS
A total of 32 randomized controlled trials were included in the final review. There was an increased odds of gynecomastia in men receiving antiandrogens (OR = 17.38, 95% CI: 11.26 to 26.82; 6 trials, 9599 participants) and 5 alpha-reductase inhibitors compared to controls (OR = 1.77, 95% CI: 1.53 to 2.06; 7 series out of 6 trials, 34860 participants). The use of spironolactone in mixed gender populations was characterized by significantly higher odds of having gynecomastia compared to controls (OR = 8.39, 95% CI: 5.03 to 13.99; 14 trials, 3745 participants). No placebo-controlled trials focusing on the risk of gynecomastia in patients taking antipsychotic drugs was available, although there was a significant difference in the odds of having gynecomastia in a comparison between risperidone and quetiapine (OR = 4.32, 95% CI: 1.31 to 14.27; 3 trials, 343 participants). Limited evidence about the effects of statins on mammary glands was found.
CONCLUSIONS
Antiandrogens and to a lesser extent 5 alphareductase inhibitors and spironolactone are associated with an increased risk of developing gynecomastia. Such effect can be explained by a modification of the testosterone to estradiol ratio. Gynecomastia (and galactorrhea) associated to the use of conventional and certain atypical antipsychotics can be related to high prolactin levels.

BACKGROUND
Clinicians and healthcare policymakers have been drenched with a deluge of overlapping meta-analyses (MAs), and the necessity for comprehensive and clearly defined evidence of Janus kinase inhibitors (JKIs) in atopic dermatitis (AD) is urgent.
METHODS
Six databases were searched for MAs published until October 2023. Qualitative description of MAs was mainly used, and Investigator's Global Assessment response (IGA response), the 75% improvement in Eczema Area and Severity Index (the EASI75), peak pruritus Numerical rating score (PP-NRS), and adverse effects were cited to describe the efficacy and safety of JKIs. The methodological quality of the included MAs was assessed by A Measurement Tool to Assess Systematic Reviews II (AMSTAR II), and the quality of evidence was evaluated by the grading of recommendations, assessment, development, and evaluation (GRADE).
RESULTS
Sixteen MAs were pooled in this review, of which five studies appraised JKIs, five appraised systemic JKIs, five papers assessed abrocitinib only, and one assessed baricitinib. Two studies were of "high" methodological quality and 14 MAs were of "moderate" quality. Eleven MAs integrated the results of JKIs and reported that JKIs provide faster onset of IGA response (RR=2.83, 95% CI [2.25, 3.56], high-quality evidence). Similarly, 10 MAs showed that JAK inhibitors were more effective in improving the EASI75 (RR=2.84, 95% CI [2.2, 3.67], high-quality evidence). Results from 12 MAs showed JKIs were active in reducing the PP-NRS (SMD=-0.49, 95% CI [-0.67, -0.32]). All MAs affirmed JKIs added no adverse effects leading to discontinuation and serious adverse events (P<0.05). However, 200mg of abrocitinib had a higher risk of acne (RR=4.34, 95% CI [1.61, 11.71), herpes zoster (RR=1.64, 95% CI [0.42, 6.39]), headache (RR=1.76, 95% CI [1.03, 3]), and nausea (RR=7.81, 95% CI [3.84, 15.87]). Upadacitinib was known to increase acne (RR=6.23, 95% CI [4.08, 9.49]), nasopharyngitis (RR=1.36, 95% CI [1.03, 1.8]) and blood creatine phosphokinase (blood CPK) (RR=2.41, 95% CI [1.47, 3.95]). Baricitinib at 2mg was associated with increased blood CPK (RR=2.25, 95% CI [1.1, 2.97]).
CONCLUSION
Compared to placebo or dupilumab, the administration of JKIs can ameliorate IGA response more effectively, improve the EASI75, and relieve pruritus without severe adverse effect, while accompanied by more acne, nasopharyngitis, headache, and digestive disturbances. The curative effect of 200 mg of abrocitinib is significant and more caution should be given in patients with gastrointestinal dysfunction, herpes zoster, and those who are acne-prone. Baricitinib and upadacitinib should be avoided in populations at high risk for cardiovascular events.

Meta-Analysis
INTRODUCTION
Dementia-related psychosis (DRP) is characterized by hallucinations and delusions, which may increase the debilitating effects of underlying dementia. This network meta-analysis (NMA) evaluated the comparative efficacy, safety, and acceptability of atypical antipsychotics (AAPs) commonly used off label to treat DRP.
METHODS
We included 22 eligible studies from a systematic literature review of AAPs (quetiapine, risperidone, olanzapine, aripiprazole, and brexpiprazole) used off label to treat DRP. Study outcomes were: (1) efficacy-neuropsychiatric inventory-nursing home (NPI-NH psychosis subscale), (2) safety-mortality, cerebrovascular events (CVAEs), and others (somnolence, falls, fractures, injuries, etc.), and (3) acceptability-discontinuations due to all causes, lack of efficacy, and adverse events (AEs). We used random-effects modeling to estimate pooled standardized mean differences (SMDs) for NPI-NH psychosis subscale scores and odds ratios (OR) for other dichotomous outcomes, with their respective 95% confidence intervals (CIs).
RESULTS
Compared with placebo, aripiprazole (SMD - 0.12; 95% CI - 0.31, 0.06), and olanzapine (SMD - 0.17; 95% CI - 0.04; 0.02) demonstrated small, non-significant numerical improvements in NPI-NH psychosis scores (5 studies; n = 1891), while quetiapine (SMD 0.04; 95% CI - 0.23, 0.32) did not improve symptoms. The odds of mortality (15 studies, n = 4989) were higher for aripiprazole (OR 1.58; 95% CI 0.62, 4.04), brexpiprazole (OR 2.22; 95% CI 0.30, 16.56), olanzapine (OR 2.21; 95% CI 0.84, 5.85), quetiapine (OR 1.68; 95% CI 0.70, 4.03), and risperidone (OR 1.63; 95% CI 0.93, 2.85) than for placebo. Risperidone (OR 3.68; 95% CI 1.68, 8.95) and olanzapine (OR 4.47; 95% CI 1.36, 14.69) demonstrated significantly greater odds of CVAEs compared to placebo. Compared with placebo, odds of all-cause discontinuation were significantly lower for aripiprazole (OR 0.71; 95% CI 0.51, 0.98; 20 studies; 5744 patients) and higher for other AAPs. Aripiprazole (OR 0.5; 95% CI 0.31, 0.82) and olanzapine (OR 0.48; 95% CI 0.31, 0.74) had significantly lower odds of discontinuation due to lack of efficacy (OR 12 studies; n = 4382) compared to placebo, while results for quetiapine and risperidone were not significant. Compared with placebo, the odds of discontinuation due to AEs (19 studies, n = 5445) were higher for olanzapine (OR 2.62; 95% CI 1.75, 3.92), brexpiprazole (OR 1.80; 95% CI 0.80, 4.07), quetiapine (OR 1.25; 95% CI 0.82, 1.91), aripiprazole (OR 1.38; 95% CI 0.90, 2.13), and risperidone (OR 1.41; 95% CI 1.02, 1.94).
CONCLUSIONS
Overall results demonstrate that, compared with placebo, quetiapine is not associated with improvement in psychosis in patients with dementia, while olanzapine and aripiprazole have non-significant small numerical improvements. These off-label AAPs (quetiapine, risperidone, olanzapine, aripiprazole, and brexpiprazole) are associated with greater odds of mortality, CVAEs, and discontinuations due to AEs than placebo. These results underscore the ongoing unmet need for newer pharmacological options with a more favorable benefit-risk profile for the treatment of DRP.

Review
Mucositis is a common and most debilitating complication associated with the cytotoxicity of chemotherapy. The condition affects the entire alimentary canal from the mouth to the anus and has a significant clinical and economic impact. Although oral and intestinal mucositis can occur concurrently in the same individual, these conditions are often studied independently using organ-specific models that do not mimic human disease. Hence, the purpose of this scoping review was to provide a comprehensive yet systematic overview of the animal models that are utilised in the study of chemotherapy-induced mucositis. A search of PubMed/MEDLINE and Scopus databases was conducted to identify all relevant studies. Multiple phases of filtering were conducted, including deduplication, title/abstract screening, full-text screening, and data extraction. Studies were reported according to the updated Preferred Reporting Items for Systematic reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. An inter-rater reliability test was conducted using Cohen's Kappa score. After title, abstract, and full-text screening, 251 articles met the inclusion criteria. Seven articles investigated both chemotherapy-induced intestinal and oral mucositis, 198 articles investigated chemotherapy-induced intestinal mucositis, and 46 studies investigated chemotherapy-induced oral mucositis. Among a total of 205 articles on chemotherapy-induced intestinal mucositis, 103 utilised 5-fluorouracil, 34 irinotecan, 16 platinum-based drugs, 33 methotrexate, and 32 other chemotherapeutic agents. Thirteen articles reported the use of a combination of 5-fluorouracil, irinotecan, platinum-based drugs, or methotrexate to induce intestinal mucositis. Among a total of 53 articles on chemotherapy-induced oral mucositis, 50 utilised 5-fluorouracil, 2 irinotecan, 2 methotrexate, 1 topotecan and 1 with other chemotherapeutic drugs. Three articles used a combination of these drugs to induce oral mucositis. Various animal models such as mice, rats, hamsters, piglets, rabbits, and zebrafish were used. The chemotherapeutic agents were introduced at various dosages via three routes of administration. Animals were mainly mice and rats. Unlike intestinal mucositis, most oral mucositis models combined mechanical or chemical irritation with chemotherapy. In conclusion, this extensive assessment of the literature revealed that there was a large variation among studies that reproduce oral and intestinal mucositis in animals. To assist with the design of a suitable preclinical model of chemotherapy-induced alimentary tract mucositis, animal types, routes of administration, dosages, and types of drugs were reported in this study. Further research is required to define an optimal protocol that improves the translatability of findings to humans.

Meta-Analysis Review
CONTEXT
The ablative effect of intravesical therapy is known for decades. However, the clinical feasibility and efficacy of chemoablation for non-muscle-invasive bladder cancer (NMIBC) have not become accepted.
OBJECTIVE
To assess the treatment outcomes of chemoablation for NMIBC and to compare its safety with that of the standard treatment, transurethral resection of bladder tumors (TURBT) followed by intravesical therapy.
EVIDENCE ACQUISITION
Multiple databases were queried in July 2022 for studies investigating the complete response (CR) rates and adverse events in NMIBC patients treated with chemoablation using mitomycin C (MMC), gemcitabine, epirubicin, or bacillus Calmette-Guérin.
EVIDENCE SYNTHESIS
Overall, 23 studies comprising 1199 patients were eligible for this meta-analysis. Among these studies, 20 assessed the efficacy of chemoablation and three compared the treatment outcomes of MMC chemoablation versus standard treatment. Among patients treated with weekly administration of any agent, the pooled CR rates at initial assessment were 50.9% (95% confidence interval [CI]: 45.9-55.9) for the marker lesion and 47.5% (95% CI: 36.5-58.7) for well-selected NMIBC (ie, small tumors and/or a small number of tumors). Novel regimens for chemoablation such as MMC-gel (70.6%, 95% CI: 60.1-79.3) and an intensive MMC regimen (64.7%, 95% CI: 56.2-72.3) provided better CR rates in well-selected NMIBC patients. Comparable CR rates were noted irrespective of tumor multiplicity, whereas tumor size <5 mm was associated with a higher CR rate than tumor size ≥5 mm (odds ratio: 0.36, 95% CI: 0.17-0.79). The novel intensive MMC regimen resulted in lower rates of dysuria and urinary frequency than standard treatment.
CONCLUSIONS
Despite the lack of long-term outcomes, chemoablation appears to be a promising treatment option for well-selected NMIBC patients and can potentially help avoid unnecessary TURBT, specifically in some elderly patients with intermediate-risk NMIBC. Further well-designed studies with larger cohorts are necessary to address the differential tolerability and long-term anticancer efficacy of this resurging approach.
PATIENT SUMMARY
Bladder instillation therapy has a potential ablative effect for well-selected non-muscle-invasive bladder cancer. This can lead to the omission of an unnecessary surgical treatment.

Meta-Analysis Review
OBJECTIVE
There is inconsistent evidence that zidovudine use during pregnancy increases overall, cardiac, and male genital malformations.
DESIGN
We conducted a systematic review and meta-analysis of zidovudine use and malformations and, using Bayesian methods, combined it with data from a cohort study of mother-infant pairs in the nationwide Medicaid Analytic eXtract (MAX).
METHODS
Using MAX data (2000-2010), we identified pregnant women with HIV treated with antiretroviral therapy (ART). Women with at least one zidovudine dispensing during the first trimester were compared to women receiving ART without zidovudine in the first trimester. Malformation outcomes were defined using diagnosis/procedure codes. To adjust for confounding, we performed 1 : 1 propensity score matching. Bayesian methods require specification of a prior, which we developed in the meta-analysis. Logistic regression models combined MAX data with the prior, estimating odds ratios (ORs) and 95% credible intervals.
RESULTS
Fourteen articles contributed information on overall malformations, seven on cardiac malformations, and five on male genital malformations. In MAX, matching led to a sample of 735 women each in the zidovudine and comparator groups. When comparing first trimester zidovudine use to other ART, the Bayesian procedure yielded OR estimates slightly above the null for overall [OR = 1.11, 95% credible interval (0.80-1.55)] and cardiac [OR = 1.30 (0.63-2.71)] malformations. There were no zidovudine-exposed cases of male genital malformations in MAX, but the meta-analysis yielded elevated OR estimates [OR = 2.57 (1.26-5.24)].
CONCLUSION
For most malformations, first-trimester zidovudine was not associated with increased risk. The potential increase in male genital malformations was small in absolute terms, and should be evaluated further.

Meta-Analysis Review
OBJECTIVES
Since the US Food and Drug Administration (FDA) approved ibrutinib to treat patients with refractory/relapsed mantle cell lymphoma (R/R MCL), it is used in clinical trials, whether as a single agent or in combination with other chemotherapy agents. The efficacy and safety of ibrutinib administration alone or in combinations have not been studied systematically. This study systematically reviewed the efficacy and safety of ibrutinib-containing regimens for the treatment of patients with MCL.
EVIDENCE ACQUISITION
We performed a systematic search in PubMed, Cochrane CENTRAL, Embase, Web of Science, and Scopus. Then, a team of independent reviewers selected relevant studies and extracted the data.
RESULTS
From a total of 1,436 studies, 12 trials were eligible. The overall response rates (ORRs) of patients with R/R MCL receiving single-agent ibrutinib ranged between 62.7% to 93.8%, and the ORRs of ibrutinib combinations ranged from 74 to 88%. In patients with newly diagnosed MCL receiving ibrutinib and rituximab, ORR ranged from 84 to 100%. The highest progression-free survival (PFS) was reported in patients receiving ibrutinib and rituximab (43 months). The meta-analysis performed on adverse events (AEs) demonstrated that single-agent ibrutinib had a high risk of bleeding, nausea, and diarrhea.
CONCLUSION
Single-agent ibrutinib showed acceptable efficacy and safety in the treatment of patients with MCL. Moreover, combining ibrutinib with other agents such as rituximab, venetoclax, and ublituximab can increase its efficacy and reduce chemotherapy-induced resistance in most cases; however, in the case of combination therapy, patients need to be monitored more strictly in terms of AEs. In our review, the ibrutinib and rituximab combination showed promising results in patients with R/R MCL. Also, this combination showed favorable efficacy and safety in patients with newly diagnosed untreated MCL, making it a great candidate to be studied more in large and well-designed trials.

Meta-Analysis Review
BACKGROUND
Cocaine dependence is a public health problem characterised by recidivism and a host of medical and psychosocial complications. Cocaine dependence remains a disorder for which no pharmacological treatment of proven efficacy exists.
OBJECTIVES
To evaluate the efficacy and the acceptability of antipsychotic medications for cocaine dependence.
SEARCH METHODS
This review is an update of a previous Cochrane review published in 2007. We searched up to 15 July 2015 in Cochrane Drugs and Alcohol Group Specialised Register (searched in CRSLive); the Cochrane Library (including the Cochrane Central Register of Controlled Trials (CENTRAL); the Database of Abstracts of Reviews of Effects (DARE)); PubMed; EMBASE; CINAHL and Web of Science. All searches included non-English language literature.
SELECTION CRITERIA
All randomised controlled trials and controlled clinical trials with focus on the use of any antipsychotic medication for the treatment of cocaine dependence.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane.
MAIN RESULTS
We included 14 studies (719 participants). The antipsychotic drugs studied were risperidone, olanzapine, quetiapine, lamotrigine, aripiprazol, haloperidol and reserpine. Comparing any antipsychotic drugs versus placebo, we found that antipsychotics reduced dropout: eight studies, 397 participants, risk ratio (RR) 0.75 (95% confidence interval (CI) 0.57 to 0.97), moderate quality of evidence. We found no significant differences for any of the other primary outcomes considered: number of participants using cocaine during the treatment, two studies, 91 participants: RR 1.02 (95% CI 0.65 to 1.62); continuous abstinence, three studies, 139 participants: RR 1.30 (95% CI 0.73 to 2.32); side effects, six studies, 291 participants: RR 1.01 (95% CI 0.93 to 1.10); and craving, four studies, 240 participants: RR 0.13 (-1.08 to 1.35). For all of these comparisons we rated the quality of evidence as low.Comparisons of single drug versus placebo or versus another drug are conducted in few trials with small sample sizes, limiting the reliability of the results. Among these comparisons, only quetiapine seemed to outperform placebo in reducing cocaine use, measured by grams per week: mean difference (MD) -0.54 (95% CI -0.92 to -0.16), by US dollars spent per week: MD -53.80 (95% CI -97.85 to -9.75), and by craving: MD -1.23 (95% CI -2.19 to -0.27), but results came from one study with 60 participants.The major limitations of the studies were the high risk of attrition bias (40% of the included studies) and low quality of reporting, mainly for the risk of selection bias, performance and detection bias, that we rated as being at unclear risk for 75% to 80% of the studies. Furthermore, most of the included studies did not report results on important outcomes such as side effects, or use of cocaine during treatment and craving, which prevented the possibility of including them in statistical synthesis.
AUTHORS' CONCLUSIONS
At present, there is no evidence supporting the clinical use of antipsychotic medications in the treatment of cocaine dependence, although results come from only 14 trials, with small sample sizes and moderate to low quality of evidence.
