Background: Cytomegalovirus (CMV) infection remains a major cause of morbidity, mortality, and increased healthcare burden in recipients of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Its clinical manifestations range from asymptomatic CMV replication to end-organ diseases such as pneumonia, gastroenteritis, and retinitis, all of which are associated with a higher rate of nonrelapse mortality. Methods: We reviewed case records of children who underwent allo-HSCT at our center between April 2013 and October 2024. CMV monitoring was performed weekly until at least day +100 post-HSCT using a quantitative polymerase chain reaction assay. All patients received acyclovir prophylaxis. Pre-emptive intravenous ganciclovir therapy was initiated when CMV-DNA levels exceeded 500 IU/mL Results: A total of 150 consecutive patients (58% male) were included. The median age at HSCT was 6.3 years (interquartile range [IQR], 3.4–11.3 years). Indications for HSCT were hematologic malignancy (n=81, 54.0%), inborn errors of immunity and bone marrow failure (n=46, 30.7%), and hemoglobinopathy (n=23, 15.3%). Donor and recipient CMV seropositivity rates were 86.7% and 94.0%, respectively. CMV infection occurred in 43.4% of patients, with a median onset of 30 days post-HSCT (IQR, 21–47 days). There were five (3.3%) cases of CMV disease, resulting in one (0.7%) CMV-related death. Human leukocyte antigen (HLA)-haploidentical donor status (odds ratio [OR], 5.00; 95% confidence interval [CI], 2.43–10.29; P<0.001) and the use of serotherapy in the conditioning regimen (OR, 2.87; 95% CI, 1.47–5.60; P=0.002) were significantly associated with an increased risk of CMV infection. Conclusions CMV infection was a common occurrence, particularly among patients with HLA-haploidentical donors. Preventive strategies such as weekly surveillance and pre-emptive ganciclovir therapy proved effective in preventing overt CMV disease.

This randomized control pilot study quantified the efficacy of interactive virtual reality golf training on balance performance among community mobile older person. Eight older women were assigned randomly to a conventional mat exercises program group (n = 4, mean age = 51 ± 1.6 years old) or an experimental group that participated in interactive virtual reality golf (n = 4, mean age = 53.5 ± 1.4 years old). Balance assessments of all participants included Multi-Directional Reach Test (MDRT), Step Up Test (SUT), Double Leg Static Balance (DLSB) with eyes open and closed and excursion of centre of pressure (COP) sway quantified with a force plate. One subject dropped out from the experimental group and three subjects from the conventional mat exercise group due to work commitments to complete the once a week study for four weeks. No significant differences in base-line balance abilities were found between groups. The experiment group did not have significant improvements in balance capability compared with control subjects (MDRT p = 0.16-0.66; SUT p = 0.05; COP during DLSB p = 0.18-0.66). However, virtual reality golf intervention improved medial-lateral sway by 57.24% during DLSB compared to 14.99% after floor-mat exercises. The improvement in COP during DLSB after interactive virtual reality golf hints towards improved postural control. Further studies with a larger population should explore using off-the shelf interactive virtual reality sports for balance training. This novel technology can complement rehabilitation programs.
