Anthracyclines play an important role in the management of patients with cancer but the development of anthracycline-induced cardiotoxicity (ACT) remains a significant concern for most clinicians. Recently, genetic approach has been used to identify patients at increased risk of ACT. This systematic review assessed the association between genomic markers and ACT. A systematic literature search was performed in Medline, PubMed, Cochrane Central Register of Controlled Studies, CINAHL Plus, AMED, EMBASE and HuGE Navigator from inception until May 2016. Twenty-eight studies examining the association of genetic variants and ACT were identified. These studies examined 84 different genes and 147 single nucleotide polymorphisms. Meta-analyses showed 3 risk variants significantly increased the risk for ACT; namely ABCC2 rs8187710 (pooled odds ratio: 2.20; 95% CI: 1.36-3.54), CYBA rs4673 (1.55; 1.05-2.30) and RAC2 rs13058338 (1.79; 1.27-2.52). The current evidence remains unclear on the potential role of pharmacogenomic screening prior to anthracycline therapy. Further research is needed to improve the diagnostic and prognostic role in predicting ACT.

Warfarin care bundles (e.g. genotype-guided warfarin dosing, patient's self-testing [PST] or patient's self-management [PSM] and left atrial appendage closure) are based on the concept of combining several interventions to improve anticoagulation care. NOACs are also introduced for stroke prevention in atrial fibrillation (SPAF). However, these interventions have not been compared in head-to-head trials yet. We did a network meta-analysis based on a systematic review of randomized controlled trials comparing anticoagulant interventions for SPAF. Studies comparing these interventions in adults, whether administered alone or as care bundles were included in the analyses. The primary efficacy outcome was stroke and the primary safety outcome was major bleeding. Thirty-seven studies, involving 100,142 patients were assessed. Compared to usual care, PSM significantly reduced the risk of stroke (risk ratio [RR] 0.24, 95% CI 0.08-0.68). For major bleeding, edoxaban 60 mg (0.80, 0.71-0.90), edoxaban 30 mg (0.48, 0.42-0.56), and dabigatran 110 mg (0.81, 0.71-0.94) significantly reduced the risk of major bleeding compared with usual warfarin care. Cluster rank plot incorporating stroke and major bleeding outcomes indicates that some warfarin care bundles perform as well as NOACs. Both interventions are therefore viable options to be considered for SPAF. Additional studies including head-to-head trials and cost-effectiveness evaluation are still warranted.

The effects of telemedicine strategies on the management of diabetes is not clear. This study aimed to investigate the impact of different telemedicine strategies on glycaemic control management of type 2 diabetes patients. A search was performed in 6 databases from inception until September 2016 for randomized controlled studies that examined the use of telemedicine in adults with type 2 diabetes. Studies were independently extracted and classified according to the following telemedicine strategies: teleeducation, telemonitoring, telecase-management, telementoring and teleconsultation. Traditional and network meta-analysis were performed to estimate the relative treatment effects. A total of 107 studies involving 20,501 participants were included. Over a median of 6 months follow-up, telemedicine reduced haemoglobin A1c (HbA1c) by a mean of 0.43% (95% CI: -0.64% to -0.21%). Network meta-analysis showed that all telemedicine strategies were effective in reducing HbA1c significantly compared to usual care except for telecase-management and telementoring, with mean difference ranging from 0.37% and 0.71%. Ranking indicated that teleconsultation was the most effective telemedicine strategy, followed by telecase-management plus telemonitoring, and finally teleeducation plus telecase-management. The review indicates that most telemedicine strategies can be useful, either as an adjunct or to replace usual care, leading to clinically meaningful reduction in HbA1c.

Anti-tuberculosis drug induced liver injury (Anti-TB DILI) is the most common adverse events (AEs) necessitating therapy interruption but there is no preventing regimen. This study aimed to examine the efficacy and safety of herbs/alternative medicines for preventing anti-TB DILI. Relevant articles were identified through a systematic search in 5 international databases from inception till March 2022. All randomized controlled trials (RCT) assessing the effects of herbal or alternative medicines against anti-TB DILI were included. The network meta-analysis (NMA) was used to synthesize the evidence for preventing hepatotoxicity using a random-effects model. A total of 3423 patients from 14 RCTs were included. The NMA indicated that supplementation of Turmeric plus Tinospora cordifolia (RR 0.07; 95% CI 0.02 to 0.28), and N-acetyl cysteine (NAC) (RR 0.09; 95% CI 0.01 to 0.75) significantly reduced the incidence of anti-TB DILI compared with placebo. In addition, poly herbal product significantly reduced alkaline phosphatase (ALP) (MD - 21.80; 95% CI - 33.80 to - 9.80) and total bilirubin (Tbil) compared with placebo (MD - 0.51; 95% CI - 0.76 to - 0.26). There was no statistically significant difference in the occurrence of AEs in any intervention. In conclusion, Turmeric plus Tinospora cordifolia, NAC and poly-herbal product may provide benefit for preventing anti-TB DILI in TB patients. However, these findings are based on a small number of studies. Additional studies are warranted to confirm the findings.

Since licensing in 2006, there has been poor uptake of the HPV vaccine among the targeted population in the South East Asia Region (SEAR) and Western Pacific Region (WPR). A systematic review was conducted to identify the studies exploring the relationship between factors and intention for HPV vaccination among women in SEAR and WPR countries. Nineteen studies were identified as suitable for qualitative synthesis, and three as suitable for meta-analysis. Most women had a positive intention to have an HPV vaccine (range 57%-85%). Having a positive intention to vaccinate was significantly higher among women not aware of HPV infection (OR: 1.34, 95% CI: 1.02-1.76) and HPV vaccine (OR: 1.57, 95% CI: 1.26-1.96). Lower knowledge level and less confidence in safety and efficacy of the vaccine, negatively affected intention to vaccinate. Perceiving the vaccine to be expensive, low perception of contracting HPV infection and cervical cancer, and lack of concrete recommendations from healthcare providers also negatively affected intention to vaccinate. This review suggests the decision-making processes of women in SEAR and WPR is influenced by the cost of vaccination, perceived efficacy and safety of vaccine, provision of information on vaccination, and the awareness about HPV infection and the HPV vaccine.

To date, evidence on optimal anticoagulant options in patients with AF who concurrently have active cancer remains elusive. To describe anticoagulant patterns and clinical outcomes among patients with a concomitant diagnosis of AF and cancer. Data were obtained from the University of Utah and Huntsman Cancer Institute (HCI) Hospitals. Patients were included if they had diagnosis of AF and cancer. Outcome was type and pattern of anticoagulant. Clinical outcomes were stroke, bleeding and all-cause mortality. From October 1999 to December 2020, there were 566 AF patients who concurrently had active cancer. Mean age ± standard deviation was 76.2 ± 10.7 and 57.6% were males. Comparing to warfarin, patients who received direct oral anticoagulant (DOACs) were associated with similar risk of stroke (adjusted hazard ratio, aHR 0.8, 95% confidence interval [CI] 0.2-2.7, P = 0.67). On contrary, those who received low-molecular-weight heparin (LMWH) were associated with significantly higher risk of stroke comparing to warfarin (aHR 2.4, 95% CI 1.0-5.6, P = 0.04). Comparing to warfarin, DOACs and LMWH was associated with similar risk of overall bleeding with aHR 1.1 (95% CI 0.7-1.6, P = 0.73) and aHR 1.1 (95% CI 0.6-1.7, P = 0.83), respectively. Patients who received LMWH but not DOACs were associated with increased risk of death as compared to warfarin, aHR 4.5 (95% CI 2.8-7.2, P < 0.001) and 1.2 (95% CI 0.7-2.2, P = 0.47). In patients with active cancer and AF, LMWH, compared to warfarin, was associated with an increased risk of stroke and all-cause mortality. Furthermore, DOACs was associated with similar risk of stroke, bleeding and death as compared to warfarin.

Centella asiatica (L.) Urb. has been used as an herbal brain tonic for mental disorders and enhancing memory, but no review of the overall evidence of C. asiatica and cognitive function has been conducted. This study aims to determine the effects of C. asiatica on cognitive function and its related properties. The current systematic review includes five randomized controlled trials (RCTs) conducted to determine the effect of C. asiatica alone and six RCTs conducted to determine the effect of C. asiatica-containing products. Meta-analysis indicated that there are no significant differences in all cognitive function domains of C. asiatica when compared to placebo. However, it could improve mood by increasing alert scores [SMD: 0.71 (95% CI; 0.01 to 1.41); I2 = 30.5%] and decreasing anger scores at 1 hour after treatment [SMD: -0.81 (95%CI; -1.51 to -0.09); I2 = 36.6%]. None of the studies reported adverse effects of C. asiatica. In conclusion, there is not strong evidence to support the use of C. asiatica for cognitive function improvement in each cognitive domain. C. asiatica could improve alertness and relieve anger. However, some limitations should be aware including dose regimen, plant preparation, standardization, and product variation. Future well-designed clinical trials using suitable doses of standardized C. asiatica are still needed.
