From an initial thought of being used as a cellular garbage bin to a promising target for liquid biopsies, the role of exosomes has drastically evolved in just a few years of their discovery in 1983. Exosomes are naturally secreted nano-sized vesicles, abundant in all types of body fluids and can be isolated intact even from the stored biological samples. ⋯ However, there are certain limitations to overcome which restrict the use of exosome-based liquid biopsy as a gold standard testing procedure in routine clinical practices. The present review summarizes the current knowledge on the role of exosomes as the liquid biopsy tool in diagnosis, prognosis and treatment response monitoring in communicable and non-communicable diseases and highlights the major limitations, technical advancements and future prospects of the utilization of exosome-based liquid biopsy in clinical interventions.

Leprosy, an ancient disease, continues to be a public health concern as it remains endemic in several countries. After reaching the elimination target (1/10,000) as a public health problem in 2005 in India, around 1.2 lakh cases have been detected every year over the last decade indicating active transmission of leprosy bacillus (Mycobacterium leprae). Single-nucleotide polymorphisms (SNPs), genomic insertions/deletions and variable-number tandem repeats (VNTRs) have been identified as genetic markers for tracking M. leprae transmission. ⋯ Molecular studies of leprosy can provide better insight into phylogeographic markers to monitor the transmission dynamics and emergence of antimicrobial resistance. An improved understanding of M. leprae transmission is essential to guide efficient leprosy control strategies. Therefore, this review compiles and discusses the current status of molecular epidemiology, genotyping and the potential of genome-wide analysis of M. leprae strains in the Indian context.

Iron deficiency anaemia (IDA) during pregnancy is treated with oral and parenteral iron. The objective of this review was to compare the clinical effectiveness, safety, pregnancy and neonatal outcomes of intravenous (iv) ferric carboxymaltose (FCM) and iv iron sucrose (IS) in treating IDA in pregnancy. ⋯ Intravenous FCM is effective and safer than intravenous IS in terms of haematological parameters, in treating IDA in pregnancy. Further research is required on the effects of iv FCM and iv IS on the pregnancy and neonatal outcomes when used for treating IDA in pregnancy.

Rabies is a lethal viral disease transmitted through the bite of rabid animals. India has a high burden of rabies, contributing to a significant proportion of the global deaths. ⋯ Laboratory diagnosis of rabies plays a crucial role in differentiating the disease from clinical mimics, initiation of appropriate care, implementing infection control measures and informing disease surveillance. This review provides an overview of the recent advancements in laboratory diagnosis of rabies, aimed at updating physicians involved in diagnosis and management of rabies cases in India.

The prong 2 of 4 prong strategy introduced by the World Health Organization aims at averting unintended pregnancies among people living with HIV (PLHIV). This systematic review aimed to generate evidence on the effectuality of facility-based interventions in improving uptake of modern and dual contraception, for reducing unmet family planning (FP) needs and unintended pregnancies among PLHIV. ⋯ The results of this meta-analysis suggest that health facility-based interventions to integrate HIV and FP services do result in improved uptake of dual methods and reduce unmet need for contraception along with a protective trend on incidence of unintended pregnancies. Such facility-based integration would ensure universal access to effective contraception and facilitate in achieving Sustainable Development Goals that aim at ending epidemics like HIV.
