Plasmodium vivax (P. vivax) malaria is a major problem in various countries such as America, Southeast Asia, Africa and the Eastern Mediterranean. The major barrier in controlling P. vivax malaria is its ability to remain in the liver as a hypnozoite form which is responsible for relapse of P. vivax malaria; hence it is necessary to target both the blood (schizont) as well as the liver (hypnozoite) stages of P. vivax to prevent its relapse. A number of factors limit the use of primaquine (PQ), the currently available therapy for P. vivax (hypnozoite stage), such as haemolysis in glucose-6-phosphate dehydrogenase-deficient patients and being contraindicated in pregnant women. ⋯ TQ is active against all stages of P. vivax lifecycle. In published studies, TQ is considered a better alternative to PQ in terms of adherence, but there are some concerns regarding its safety, efficacy and study designs of trials conducted on TQ. In this context, this review, discusses the potential safety concerns, efficacy data, summary and an appraisal of findings of the important published trials of TQ.

Review
Cancer metabolomics: A tool of clinical utility for early diagnosis of gynaecological cancers.
Gynaecological cancers are the major cause of cancer-related deaths in Indian women. The poor prognosis and lack of symptoms in the early stages make early cancer diagnosis difficult. The absence of mandatory screening programmes and the lack of awareness pose to be a real challenge in a developing economy as India. ⋯ This metabolite profile is capable of differentiating the healthy individuals from those having cancer. The pathways that a cell takes in turning malignant are exceedingly different, owing to the fact that transformation of healthy cells to abnormal cells is linked with significant metabolic abnormalities. This review is aimed to discuss metabolomics and its potential role in early diagnosis of gynaecological cancers, viz. breast, ovarian and cervical cancer.

Despite advances in diagnostics and therapeutics, tuberculosis (TB) is widely prevalent and contributes to a significant burden of illness in both developing and developed nations. The present study was aimed to assess the role of coronin in TB patients and healthy controls. Coronin is a leucocyte-specific protein that is actively recruited in mycobacterial phagolysosomes, where it inhibits lysosomal delivery of Mycobacterium by activating a calcium-dependent phosphatase-calcineurin. ⋯ Coronin 1a appears to play an important role in the TB disease pathophysiology and agents developed against coronin may have a role in the treatment of TB. Further studies are required to assess if coronin-1a levels are elevated in non-tubercular infective a etiologies and whether these can be a potential drug target in patients with TB.

Observational Study
Clinicopathological study of annexin A5 & apelin in pre-eclamptic placentae with emphasis on foetal outcome.
Pre-eclampsia has remained an elusive disease with serious impacts on both maternal and foetal health. Two novel markers, annexin A5 (ANXA5) and apelin are currently of considerable interest. The present study aimed to determine the placental expression of ANXA5 and apelin in pre-eclamptic placentae and also to elucidate if there is any correlation between the expression of these markers and the clinical features of both, mother and neonate. The comparison between gross and histopathological features of pre-eclamptic placentae and controls was another objective. ⋯ The results of the present study suggest that both ANXA5 and apelin levels are reduced in pre-eclamptic placentae. Hence, it is recommended to further explore the impact of these markers on pregnancy outcomes by undertaking randomized controlled trials.
