As Malaysia races towards a developed nation status, children are increasingly being ferried daily in vehicles almost exclusively as the majority of the population are able to afford private transportations. This paper reviews the current safety concerns for children whilst going in vehicles on Malaysian roads and the steps undertaken to address the need to enhance children’s safety whilst going in these vehicles and suggest possible remedial action to counter the possible lack of awareness for children’s safety whilst in these vehicles. This paper focuses on children on motorcycles and private vehicles (cars, vans and multi-purpose vehicle (MPV)) and excludes other form of transport (buses, lorries) as this paper tries to put forth measures that can be undertaken by the children’s parents and guardian to better enhance the safety of their children. A search was undertaken of all the major database of articles. Articles related to children’s safety systems, children related injuries, children related accident data, available laws and legislation were reviewed to present the need for greater awareness of children’s safety while going in vehicles in Malaysia. There are currently already safety legislations, measures, steps and equipments in place in ensuring the safety of children whilst going in vehicles on Malaysian roads. However, enforcement of laws in developing countries are not easy and we have to start at the root of the problem which is the parents and adults who ferry these children in vehicles. There is a pressing need to educate parents and adults alike on the urgent undertaking of child safety whilst in vehicles. Engineering countermeasures and intervention are probably needed to protect these vulnerable users. For vehicles, a device capable of providing some sort of protection to the child whilst riding pillion should be designed and developed. A legislation mandating the use of child seats whilst ensuring the child seats are affordable to the masses.

OBJECTIVE:
To explore the genetic basis for a rare case of acute B-lymphocytic leukemia (B-ALL) with double Philadelphia chromosomes (Ph) and double derivative chromosome 9s [der(9)].
METHODS:
A patient with double Ph and double der(9) B-ALL who presented at Shanghai Zhaxin Intergrated Traditional Chinese and Western Medicine Hospital in June 2020 was selected as the subject. Bone marrow morphology, flow cytometry, G-banding karyotyping, fluorescence in situ hybridization (FISH), genetic testing and chromosomal microarray analysis (CMA) were used to analyze bone marrow samples from the patient at various stages.
RESULTS:
At initial diagnosis, the patient's bone marrow morphology and flow immunotyping have both supported the diagnosis of B-ALL. G-banded karyotyping of the patient indicated double Ph, in addition with hyperdiploid chromosomes involving translocations between chromosomes 9 and 22. BCR-ABL1 fusion gene was positive. Genetic testing at the time of recurrence revealed presence of a heterozyous c.944C>T variant in the kinase region of the ABL1 gene. FISH showed a signal for ABL1-BCR fusion on both chromosome 9s. CMA showed that the mosaicism homozygosity ratio of chromosome 9 was about 40%, and the mosaicism duplication ratio of chromosome 22 was about 43%.
CONCLUSION
Since both der(9) homologs were seen in 40% of cells, the possible mechanism for the double der(9) in this patient may be similar to that of double Ph, which might have resulted from non-disjunction during mitosis in the Ph chromosome-positive cell clone.

Objective:To investigate the efficacy and safety of different transcatheter arterial chemoembolization(TACE)-based regimens in patients with unresectable hepatocellular carcinoma(uHCC)and explore the optimal timing for combining TACE with tyrosine kinase inhibit-ors(TKIs)and immune checkpoint inhibitors(ICIs).Methods:A retrospective analysis was conducted on data from 555 patients with uHCC who underwent TACE-based treatment between April 2016 and December 2021 in Nanfang Hospital,Southern Medical University.The pa-tients were assigned into the following four groups according to different treatment regimens:TACE group(n=317),TACE combined with TKIs group(TACE+TKIs,n=66),TACE combined with ICIs group(TACE+ICIs,n=33),and TACE combined with TKIs+ICIs group(TACE+TKIs+ICIs,n=139).Subgroup analysis was performed within the TACE+TKIs+ICIs group,with patients being assigned into"pre-TACE"and"post-TACE"groups based on the timing of the combination therapy.Univariate and multivariate Cox regression analyses were conducted to identify pro-gnostic factors influencing overall survival(OS).Results:The TACE+TKIs+ICIs group showed the longest OS(21.9 months,95%confidence in-terval[CI]:17.2-26.6,P=0.030)and progression-free survival(PFS)(8.3 months,95%CI:7.3-9.3,P=0.004)compared to those in the other three groups.In the subgroup analysis,the"post-TACE"group had longer OS than the"pre-TACE"group(26.8 months vs.19.2 months,P = 0.011).The objective response rate(ORR)was 32.8%,41.1%,42.4%,and 52.5%(P=0.001)and the disease control rate(DCR)was 59.6%,71.2%,69.7%,and 82.7%(P<0.001)in the TACE,TACE+TKIs,TACE+ICIs,and TACE+TKIs+ICIs groups,respectively.The adverse events were similar to those reported in previous studies.Cox regression analysis revealed that tumor number,extrahepatic metastasis,and treatment regimen were independent factors influencing OS in patients(all P<0.05).Conclusions:TKIs or ICIs can improve OS and PFS in patients with uHCC receiving TACE,and the combination of TKIs+ICIs with TACE achieves better beneficial outcomes.The greatest OS was observed when the combination therapy TKIs+ICIs was initiated within 3 months after the first TACE procedure.
