Meta-Analysis
BACKGROUND
Vitreoretinal lymphoma (VRL) is usually treated with a combination of intraocular methotrexate (ioMTX), high-dose intravenous methotrexate (HD-MTX), or local radiotherapy (RT) as the first options. The effectiveness and safety of monotherapy like bruton's tyrosine kinase inhibitors (BTKi) for PVRL remain uncertain.
METHODS
A systematic review and meta-analysis of clinical trial data and conference abstracts in VRL patients treated with first-line combination therapy or monotherapy were conducted through a search of PubMed, Embase, and Scopus databases until December 2022. A total of 24 studies comprising 517 patients were included, and survival data were extracted from 279 patients due to inconsistent units across studies.
RESULTS
The combined treatment group used ioMTX + chemotherapy (in 4 studies), RT + chemotherapy (in 2 studies), ioMTX/HD-MTX based regimen (in 2 studies), ioMTX + RT + chemotherapy (in 2 studies), ioMTX + lenalidomide/BTKi (in 2 studies) and combination of multiple therapies (in 7 studies). The monotherapy group was mainly treated with oral monotherapies such as BTKi. The combination therapy had a higher overall response rate (ORR) and complete response rate (CRR) than monotherapy (ORR: 96% vs. 72%, CRR: 92% vs. 63%). Combination therapy also resulted in a longer median progression-free survival (28.8 months vs. 13 months, p = 0.012). However, the combination therapy group had more severe side effects (grade 3/4 toxicity) than the monotherapy group (45% vs. 8%).
CONCLUSION
The study showed combination therapy had better OR and CR rates, longer survival, and more toxicity than monotherapy. While BTK inhibitors were well-tolerated, long-term effectiveness needs confirmation from prospective studies. In addition, given the small number of studies of monotherapy for VRL, more studies are needed to validate its effects.

Review
BACKGROUND
Post-mortem interval (PMI) is the cornerstone of the forensic field to investigate. The examination technique by seeing the changes in the body such as algor mortis, rigor mortis, and livor mortis is a traditional technique in which accuracy is influenced by many factors. A biomolecular technique that uses microRNA (miRNA) biomarkers is developing because miRNA has good stability than other RNA, so it meets the requirements to be used for PMI estimation.
METHOD
Following the PRISMA guidelines, journals were taken from 5 databases: Scopus, Science Direct, PubMed, Embase, and Springer. The review was carried out by two people. Inclusion criteria in this review are original research, published in the last 10 years, discussing miRNA as a biomarker for PMI estimation, and free full access. While exclusion criteria are not original research and not using English.
RESULT
Eighteen journals were reviewed in this study. The study was conducted using test animals (rats) and human samples with tissue sources taken from the liver, skeletal muscle, blood, bone, heart, skin, saliva, semen, brain, lung, vitreous humor, spleen, and kidney. miRNA expression levels after death showed different results based on miRNA target, tissue source, and others.
DISCUSSION
The results of each study are different due to the use of different types of miRNA targets and tissue sources. miRNA has great potential to estimate PMI in forensic science, but it is necessary to control the influencing factors to obtain an accurate conclusion.
