Review Meta Analysis
Efficacy and effectiveness of influenza vaccines: a systematic review and meta-analysis.
No published meta-analyses have assessed efficacy and effectiveness of licensed influenza vaccines in the USA with sensitive and highly specific diagnostic tests to confirm influenza. ⋯ Alfred P Sloan Foundation.

Review Meta Analysis
Prevention of ventilator-associated pneumonia with oral antiseptics: a systematic review and meta-analysis.
We did a systematic review and random effects meta-analysis of randomised trials to assess the effect of oral care with chlorhexidine or povidone-iodine on the prevalence of ventilator-associated pneumonia versus oral care without these antiseptics in adults. ⋯ None.

Tuberculosis is one of the most deadly infectious diseases. The situation is worsening because of co-infection with HIV and increased occurrence of drug resistance. Although the BCG vaccine has been in use for 90 years, protection is insufficient; new vaccine candidates are therefore needed. 12 potential vaccines have gone into clinical trials. ⋯ In the long term, vaccines that prevent or eradicate infection with Mycobacterium tuberculosis would be the best possible option. Improved knowledge of immunology, molecular microbiology, cell biology, biomics, and biotechnology has paved the way towards an effective and safe vaccine against tuberculosis. The pipeline of new vaccine candidates from preclinical to clinical testing could be accelerated by development of biomarkers that can predict the clinical outcome of tuberculosis.

After the launch of the National Malaria Control Programme in 1953, the number of malaria cases reported in India fell to an all-time low of 0·1 million in 1965. However, the initial success could not be maintained and a resurgence of malaria began in the late 1960s. Resistance of Plasmodium falciparum to chloroquine was first reported in 1973 and increases in antimalarial resistance, along with rapid urbanisation and labour migration, complicated the challenge that India's large geographical area and population size already pose for malaria control. ⋯ Continued use of chloroquine for treatment of P falciparum malaria in India will likely be ineffective. Resistance to sulfa-pyrimethamine should be closely monitored to protect the effectiveness of treatment with artesunate plus sulfadoxine-pyrimethamine, which is the new first-line treatment for P falciparum malaria. Strategies to reduce the emergence and spread of future drug resistance need to be proactive and supported by intensive monitoring.

Review Meta Analysis
HIV status in discordant couples in sub-Saharan Africa: a systematic review and meta-analysis.
Most couples affected by HIV/AIDS in sub-Saharan Africa live in discordant relationships. Men are thought to be the index case in most relationships, and most social marketing and awareness campaigns are focused on men. We investigated serodiscordance in stable relationships to establish the gender balance of index-case infections. ⋯ None.
