Eye Strain During Covid

People infected with Covid-19 had a roughly 25 per cent increased risk of developing a psychiatric disorder in the four months following their infection, compared with those who had other types of respiratory tract infections, finds a study. Researchers at Oregon State University in the US found that Covid patients had a 3.8 per cent rate of developing a psychiatric disorder compared with 3.0 per cent for other respiratory tract infections. The 0.8 per cent difference amounts to about a 25 per cent increased relative risk. The team looked specifically at anxiety disorders and mood disorders and found a minor but significant increase in risk for anxiety disorders and no change in risk for mood disorders. The results speak to the need for both patients and health care providers to be more proactive when it comes to addressing mental health concerns following Covid infection, said Lauren Chan, doctoral student in nutrition in OSU's College of Public Health and Human Sciences. "For people that have had Covid, if you're feeling anxiety, if you're seeing some changes in how you're going through life from a psychiatric standpoint, it's totally appropriate for you to seek some help," Chan said. For the study, published in the journal World Psychiatry, researchers included data of 46,610 Covid-19 positive individuals and control patients who were diagnosed with a different respiratory tract infection so they could compare how Covid specifically affected patients' mental health. They looked at the rate of psychiatric diagnoses for two time periods: from 21 to 120 days after patients' Covid diagnosis, and from 120 to 365 days after diagnosis, limited to patients with no previous mental illness. When patients leave a doctor's office, sometimes care stops there, but Chan recommended that providers consider calling in two weeks for a check-in. "I don't want to say that every single person who gets Covid is going to have this type of problem, but if you start to have concern for yourself or a family member, it's not unheard of. You should definitely seek care for yourself or others around you," Chan said. Read More► Dogs Can Detect Covid-19 Faster Than Rapid Antigen Test: Study

London: Dogs are more effective at detecting Covid-19 infections through human sweat samples than the existing rapid antigen tests, according to a study. The study, published in the PLOS ONE, showed that dogs were 97 per cent effective at detecting Covid infection compared to PCR tests - the most accurate Covid test. On the other hand, the nasal antigen tests detected 84 per cent of positive Covid infections. The findings suggest a potentially less invasive and quicker Covid testing alternative. For the study, researchers at the Assistance Publique-Hopitaux de Paris included PCR and sweat samples from 335 people and antigen tests from 234 people recruited in Paris from March 16 and April 9, 2021. The researchers examined five dogs trained to sniff out Covid-19 by examining both positive and negative tests to see if they could tell. They found canines were 100 per cent accurate in detecting positive Covid cases in asymptomatic individuals compared to PCR test results. The canines were slightly less effective at identifying negative coronavirus infections, detecting 90 per cent of negative cases compared to antigen tests that were 97 per cent accurate. "Non-invasive detection of SARS-CoV-2 infection by canine olfaction could be one alternative to nasopharyngeal swabs RT-PCR when it is necessary to obtain a result very quickly according to the same indications as antigenic tests in the context of mass screening," the researchers wrote in the paper. Previous studies have shown dogs to detect malaria, prostate cancer, diabetes, Parkinson's disease and also breast cancer. (Agency) Read More► Diabetes Almost Doubles Risk of Death From Covid: Study

Two years after infection with Covid-19, half of patients who were admitted to hospital still have at least one symptom, according to the study published in The Lancet Respiratory Medicine. The study followed 1,192 participants in China infected with SARS-CoV-2 during the first phase of the pandemic in 2020. While physical and mental health generally improved over time, the analysis suggests that Covid-19 patients still tend to have poorer health and quality of life than the general population. This is especially the case for participants with long Covid, who typically still have at least one symptom including fatigue, shortness of breath, and sleep difficulties two years after initially falling ill. "Our findings indicate that for a certain proportion of hospitalised Covid-19 survivors, while they may have cleared the initial infection, more than two years is needed to recover fully from it," said lead author Professor Bin Cao, of the China-Japan Friendship Hospital, China. Six months after initially falling ill, 68 per cent of participants reported at least one long Covid symptom. By two years after infection, reports of symptoms had fallen to 55 per cent. Fatigue or muscle weakness were the symptoms most often reported and fell from 52 per cent at six months to 30 per cent at two years. Covid-19 patients were also more likely to report a number of other symptoms including joint pain, palpitations, dizziness, and headaches, pain or discomfort and anxiety or depression than non-Covid-19 participants. Long Covid participants also more often reported problems with their mobility or activity levels than those without long Covid. The authors also acknowledge limitations such as lack of control group of hospital survivors unrelated to Covid-19 infection. The team emphasised the need for follow-up of Covid survivors, particularly those with symptoms of long Covid. "There is a clear need to provide continued support to a significant proportion of people who've had Covid-19, and to understand how vaccines, emerging treatments, and variants affect long-term health outcomes," Cao said.

It is common for an expectant mother to feel stressed about pregnancy, especially those who are pregnant for the first time. It can bring up a range of emotions and anxieties. Being concerned about having a healthy pregnancy is not a bad thing because it can push people to take action in the face of new challenges. However, when the stress becomes too overwhelming, it could lead to health problems for the mother and the baby. Hence, it is necessary to consult with your doctor for a smooth and risk-free pregnancy. Understanding The Common Causes of Stress During Pregnancy Finding out that they are pregnant can be a stressful experience in itself for some women. Stress arises mostly in unplanned pregnancy. Other factors such as fear of pregnancy loss, fear of labour and delivery, financial problems, uncomfortable physical changes like nausea, tiredness, mood swings, and backaches, miscarriage, and fear of taking care of the baby when the baby is born could lead to stress among pregnant women. It's Important For Mothers to Keep Herself Stress Free Maternal stress or anxiety during pregnancy can affect the fetus, causing possible long-term consequences for infant and child development. Chronic stress can affect the mother's health and can cause headaches, problems sleeping, fast breathing, and a racing pulse. Also, it could lead to preeclampsia, miscarriage, premature birth, and low birth rate. Thus, it is important to look after the mental well-being and take care of the physical health of the mother during pregnancy. Risks of Stress to Your Baby and Pregnancy Are: Preeclampsia: Research shows that if you already have high blood pressure, you're at greater risk of getting preeclampsia during pregnancy. Preeclampsia is a potentially dangerous pregnancy complication characterised by high blood pressure. It usually begins after 20 weeks of pregnancy in a woman whose blood pressure had been normal. It can lead to complications for both mother and baby. Miscarriage: Also known as spontaneous abortion, it can be both physically and emotionally painful. Research shows that women who had major negative life events or psychological stress exposure were twice as likely to have early miscarriages. The stressers of pregnancy can trigger depression in some people. To cope up, people use harmful substances like alcohol, tobacco, and drugs. These can increase the risk of certain pregnancy complications, including miscarriage. Preterm Birth and Low Birth Rate: Studies show that mothers who experience more stress are more likely to go into labourearly.Stress can increase the chances of having a premature baby (born before 37 weeks of pregnancy) or a low-birthweight baby (who weigh less than 5 and a half lb (2.5 kg or 2500 g) at birth). Chronic stress can lead to long-term changes in the body's vascular system, hormone levels, and the ability to fight infection. All these, can potentially influence labour to start before the baby is full-term. Post-Delivery Complications Some studies show that high levels of stress during pregnancy could lead to a higher chance of the child developing attention deficit hyperactivity disorder (ADHD). Stress may also affect the baby's brain development or immune system.
