EXPERT OPINION ON DRUG SAFETY 2018, VOL. 17, NO. 11, 1129–1144.
Malaria during and after pregnancy contributes significantly to maternal mortality and adverse fetal outcomes. While effective and safe antimalarial treatments are essential, quinine — an older, less effective drug — has long bee...n favoured due to the limited safety data available on newer drugs. This review summarises the results of human studies investigating the safety and efficacy of antimalarial drugs during pregnancy and lactation.

To mark the International Day of the African Child, Medicines for Malaria Venture (MMV) celebrated the inclusion of three of its antimalarial medicines on the WHO Model List of Essential Medicines (EML) and the EML for Children (EMLc). These are two artemisinin-based combination therapies (ACTs) for... adults, children and infants, and a rectal artesunate formulation for the pre-referral treatment of severe malaria in young children. The approved therapies — pyronaridine–artesunate, dihydroartemisinin–piperaquine and rectal artesunate — offer child-friendly formulations and are the first-line treatment for uncomplicated malaria caused by Plasmodium falciparum and P. vivax. Inclusion in the EMLc facilitates national adoption, improves access to high-quality treatments and addresses the disproportionate malaria burden among children under five. This supports global efforts to reduce malaria mortality and advance elimination.

Cardiovascular diseases (CVD) represent the highest burden of disease globally. Medicines are a critical intervention used to prevent and treat CVD. This review describes access to medication for CVD from a health system perspective and strategies that have been used to promote access, including pro...viding medicines at lower cost, improving medication supply, ensuring medicine quality, promoting appropriate use, and managing intellectual property issues. Using key evidence in published and gray literature and systematic reviews, we summarize advances in access to cardiovascular medicines using the 5 health system dimensions of access: availability, affordability, accessibility, acceptability, and quality of medicines. There are multiple barriers to access of CVD medicines, particularly in low- and middle-income countries. Low availability of CVD medicines has been reported in public and private healthcare facilities. When patients lack insurance and pay out of pocket to purchase medicines, medicines can be unaffordable. Accessibility and acceptability are low for medicines used in secondary prevention; increasing use is positively related to country income. Fixed-dose combinations have shown a positive effect on adherence and intermediate outcome measures such as blood pressure and cholesterol. We have a new opportunity to improve access to CVD medicines by using strategies such as efficient procurement of low-cost, quality-assured generic medicines, development of fixed-dose combination medicines, and promotion of adherence through insurance schemes that waive copayment for long-term medications. Monitoring progress at all levels, institutional, regional, national, and international, is vital to identifying gaps in access and implementing adequate policies.

Background
The core clinical symptoms of addiction include an enhanced incentive for drug taking (craving), impaired self-control (impulsivity and compulsivity), emotional dysregulation (negative mood) and increased stress reactivity. Symptoms related to impaired self-control involve reduced activi...ty in anterior cingulate cortex (ACC), adjacent prefrontal cortex (mPFC) and other brain areas. Behavioral training such as mindfulness meditation can increase the function of control networks including those leading to improved emotion regulation and thus may be a promising approach for the treatment of addiction.
Methods
In a series of randomized controlled trials (RCTs), we tested whether increased ACC/mPFC activity is related to better self-control abilities in executive functions, emotion regulation and stress response in healthy and addicted populations. After a brief mindfulness training (Integrative Body-Mind Training, IBMT), we used the Positive and Negative Affect Schedule (PANAS) and Profile of Mood States (POMS) to measure emotion regulation, salivary cortisol for the stress response and fMRI for brain functional and DTI structural changes. Relaxation training was used to serve as an active control.
Results
In both smokers and nonsmokers, improved self-control abilities in emotion regulation and stress reduction were found after training and these changes were related to increased ACC/mPFC activity following training. Compared with nonsmokers, smokers showed reduced ACC/mPFC activity in the self-control network before training, and these deficits were ameliorated after training.
Conclusions
These results indicate that promoting emotion regulation and improving ACC/mPFC brain activity can help for addiction prevention and treatment.

Since the 1960s, the Tanzanian government has been striving to improve access to quality healthcare, including primary care. However, tuberculosis (TB) remains a significant public health concern, with an estimated prevalence rate of 528 cases per 100,000 people. However, currently, only 36% of TB c...ases are detected, leaving many undiagnosed within the community. Challenges include low community awareness, long distances to diagnostic centres and delayed health-seeking behaviour.
To address these issues, the Ministry of Health (MOHCDGEC) adopted the ENGAGE TB approach, involving NGOs, civil society organisations (CSOs) and other non-state actors in community-based TB activities. This has increased the number of active organisations from five to approximately twenty.
Building on this success, the Ministry has developed national operational guidelines for community-based TB, TB/HIV and drug-resistant TB interventions, with the aim of improving collaboration between communities and health facilities. These guidelines will be updated regularly, and stakeholders are urged to comply fully with them and support TB control efforts.

Antimalarial chemotherapy is crucial for reducing morbidity, mortality, and drug resistance, and is the cornerstone of malaria control. Existing antimalarial drugs act at different stages of the parasite’s life cycle. These drugs range from classic agents such as chloroquine and quinine to newer a...rtemisinin derivatives. They include tissue schizonticides, blood schizonticides, gametocytocides, and sporontocides. Artemisinin and its derivatives are the most effective and fastest-acting treatment against drug-resistant Plasmodium falciparum, achieving rapid parasite clearance and reducing transmission potential. Other key drugs include mefloquine, halofantrine, proguanil, sulfadoxine–pyrimethamine, atovaquone–proguanil, tetracyclines, clindamycin and azithromycin. Each of these drugs has a specific mechanism of action, pharmacokinetics, efficacy, safety profile and contraindications. Rational drug combinations and adherence to national treatment guidelines are essential for managing resistance, ensuring safety in vulnerable populations such as children and pregnant women, and optimising therapeutic outcomes in cases of both uncomplicated and severe malaria.

Combination therapy is a cornerstone of modern malaria treatment, particularly in the context of widespread multidrug resistance. Using two or more antimalarial drugs with different mechanisms simultaneously enhances efficacy, shortens treatment duration, improves compliance and delays the developme...nt of resistance. Artemisinin-based combination therapies (ACTs), such as artemether–lumefantrine, artesunate–amodiaquine and artesunate–sulfadoxine/pyrimethamine, are highly effective in rapidly clearing parasites and reducing gametocyte carriage. They are also generally well tolerated. Non-artemisinin combinations, quinine-based regimens and novel combinations (e.g. piperaquine–dihydroartemisinin) offer alternative therapeutic options, although clinical experience with these remains limited. Although ACTs are the preferred first-line treatment, factors such as cost, local drug resistance patterns, safety during pregnancy and paediatric use must inform implementation and policy decisions.
