The study led by Lithuanian University of Health Sciences compared treatment delays, post-treatment ejection fraction, and decompensated heart failure hospitalisation rate in heart attack patients before versus during the Covid-19 pandemic. Urgent treatment for heart attacks is essential to restore the flow of oxygen-rich blood to the heart muscle.

Ovarian reserve describes the ability of the ovary to produce eggs for fertilisation (natural and medical) and pregnancy. The study, led by researchers at IVI Madrid, a fertility clinic in Spain, provides further reassurance for those planning fertility treatment with IVF. The findings were presented at ESHRE's 37th annual meeting taking place online from 26 June to July 1.

The researchers extracted cells from 14 people who received the Pfizer vaccine. Samples were obtained three weeks after the first dose, and at weeks four, five and seven.

In May, the global health body had declared it as a "variant of global concern".

Researchers from the Boston Children's Hospital, have found new properties in the spike protein of the Alpha, first identified in the UK and Beta, first identified in South Africa variants. The changes to the 'spike' protein explains faster spread of Alpha, and how the Beta variant evades immune responses, suggesting the need for a booster with an updated vaccine.

Researchers from the University of New South Wales used high-speed videos of a person sneezing to identify the optimal cloth mask design. The team made simple face masks with 17 commonly available fabrics. Each mask had one, two or three layers of the same or different fabrics.

LinkedIn, an online professional network, announced findings of its latest edition of the Workforce Confidence Index based on the survey responses of 1,891 professionals from May 8 to June 4.

Researchers from the Vita-Salute San Raffaele University in Italy's Milan, identified memory, spatial awareness and information processing problems as possible overhangs from the virus in post-Covid-19 patients after eight weeks. The greater the severity of Covid-19 acute respiratory symptoms during hospital admission, the lower was the executive function performance, they found.
