Quademic 2025: Hospitals in the United States are dealing with a surge in patients admission, the reason is the quademic it is dealing with at this moment. This has led to an influx of patients. It is all caused by seasonal infections, including common flu, Covid-19, and respiratory syncytial virus (RSV) that dominate the winter season in the US. This year, norovirus also joined the list, which has further increased the load on the healthcare.

The healthcare company founded in academics M Health Fairview, confirmed that their hospitals are overflowing due to the quademic.

Is US able to cope with Quademic 2025?

The hospitals of M Health Fairview's volume is up by 30% and as a results, patients are being treated in the hallways and in alternative care areas. There is also a longer wait time and shortages for resources that are required to treat these emergencies. This has also impacted other life-threatening emergencies like heart attacks and strokes, as the healthcare resources and caregivers are occupied with the surge in seasonal cases.

What are these quademic infections?

Common cold and flu: The common cold and influenza (flu) are perhaps the most well-known illnesses that peak during the fall. As temperatures drop and humidity levels fluctuate, viruses that cause colds and the flu become more active. The flu, in particular, can be more severe than a common cold, leading to complications such as pneumonia, especially in vulnerable populations like the elderly and those with pre-existing health conditions. Symptoms include a runny nose, sore throat, coughing, fever, and body aches.

Covid-19: As per the World Health Organization, Coronavirus disease or COVID-19 is an infectious disease caused by the SARS-CoV-2 virus. Most people infected with this virus will experience mild to moderate respiratory illness and recover without requiring special treatment, However, there could be some cases of seriously ill patients who may require medical attention. It is also because of the other existing medical conditions like cardiovascular diseases, diabetes, chronic respiratory diseases, cancers, or older age.

The best way to protect against this virus is by following social isolation form those who are infected, using mask to prevent droplets from infecting others when you cough or sneeze and to wash your hands for 20 seconds frequently.

RSV or Respiratory Syncytial Virus: As per the Centers of Diseases Control and Prevention (CDC), RSV is a common respiratory virus that infects nose, throat and lungs. Though symptoms are similar to the viruses like flu or COVID-19, the disease in itself is different. It also peaks during the winter season, especially between December and January.

However, the main difference between RSV and other respiratory illness, above mentioned is that RSV can cause pneumonia or bronchiolitis, especially for those who are over the age of 50 or with an existing heart or lung disease.

Norovirus: It is a number 1 cause of foodborne illness in the US and this happens when virus gets into the food and then it accidentally enters your mouth. These particles are from faeces or vomit from infected people, or can be transmitted via contaminated food and water. It could also spread by touching unclean surfaces like door handles or cutlery.

For most people, having norovirus is unpleasant, but mild and recovery could be made in 1 to 2 days. However, it could be more serious for babies, older people and anyone with any existing health condition.

Air pollution in India, especially during winter after Diwali, is one of the alarming environmental and health concerns currently. While we are aware about its adverse effects on lungs and respiratory health, a recent review of five decades of Indian research has suggested its damages may extend to other bodily functions too.

A review of five decades of Indian research has found that more than 91% of epidemiological studies examining the health effects of air pollution reported at least one adverse health effect. These health conditions ranged from cardiovascular and metabolic diseases to pregnancy complications and cancer.

The analysis, conducted by the Centre for Research on Energy and Clean Air (CREA), examined 184 peer reviewed epidemiological studies published between 1975 and 2025.

Out of these, 169 reported at least one positive link between air pollution and an adverse health effect. The findings cement evidence linking polluted air to a wider range of health problems.

Respiratory diseases were the most frequently investigated health outcomes, featuring in 86 of the 184 studies. Sixteen studies examined mortality, while 11 focused on cardiovascular diseases.

Other research investigated connections between air pollution and diabetes, pregnancy complications, low birth weight, impaired child growth, cancers and other neoplasms, blood disorders, neurological and mental health conditions, metabolic disorders, sleep problems, eye diseases and chronic kidney and bone conditions.

The review also found that the evidence was not limited to privately funded or independent research. Of the 46 government-funded studies included, 44 reported increased health risks.

Similarly, 77 of the 81 studies affiliated with government institutions reported adverse health associations. These institutions included the Indian Council of Medical Research (ICMR), All India Institute of Medical Sciences (AIIMS), the Central Pollution Control Board (CPCB) and the Ministry of Health and Family Welfare.

The 91.8% figure represents the proportion of studies that reported at least one positive association with a health outcome.

Indian Air Pollution Crisis

Delhi accounted for the highest number of studies i.e. 26, followed by Punjab with 13, and Maharashtra and Uttar Pradesh with 11 each. However, the review also highlighted a wide gap in research outside urban centres.

Only 40 studies examined rural populations. Of these, 38 reported at least one adverse health effect linked with air pollution exposure.

The studies accounted for several sources of exposure, including outdoor pollution, household cooking and heating fuels, indoor environments like homes and workplaces, and occupational exposure.

Polluted Air Can Affect Heart And Metabolism

Fine particulate matter, like PM2.5, can travel deep into the lungs and enter the bloodstream. It can cause inflammation and oxidative stress, processes that may affect blood vessels, metabolic regulation and other organs.

Indian research has also examined the relationship between PM2.5 exposure and type 2 diabetes. A study involving 12,064 adults in Delhi and Chennai, published in BMJ Open Diabetes Research & Care in 2023, found that higher long-term PM2.5 exposure was associated with increased fasting blood glucose, HbA1c and the risk of developing type 2 diabetes. The findings were observational and do not establish that pollution alone caused diabetes.

Air pollution has also been associated with cardiovascular conditions, including hypertension, ischaemic heart disease and stroke. Meanwhile, the CREA review included studies examining neoplasms, a category that includes cancers. However, the review does not establish that 91% of studies independently linked pollution to diabetes, heart disease and cancer. These were among several health outcomes investigated.

India Needs A Better Clean-Air Strategy

The review suggests that air pollution policies need to address the wider picture. Studies examined particulate matter, including PM2.5 and PM10, as well as nitrogen dioxide, sulphur dioxide, ozone, carbon monoxide, black carbon and heavy metals.

CREA has called for stronger air-quality standards, better pollution monitoring, stricter emission limits for industries and power plants, and measures to reduce indoor pollution from solid fuels. It has also emphasised the need to include rural populations in the next phase of India's National Clean Air Programme.

Russia has reported a milestone in its experimental personalised cancer vaccine development. The first patient to complete treatment with the country's mRNA-based cancer vaccine is reportedly doing well as the follow-up scans showed no new tumour growth in the four months after completing therapy.

The update was shared by Alexander Gintsburg, scientific director of Moscow's Gamaleya Research Institute of Epidemiology and Microbiology.

According to a report published by Kursiv, the patient is undergoing monthly examinations at Russia's National Medical Research Centre for Radiology, including high-resolution CT scans. Doctors are paying attention to the lymph nodes where cancer is most likely to spread.

The patient will remain under medical observation for the next three years. While the early findings are promising, they are based on a single patient's experience, which is a major limitation.

Russia's Personalised mRNA Cancer Vaccine

The treatment, known as NeoOncovac, is a personalised cancer vaccine developed with the help of messenger RNA (mRNA) technology.

Unlike preventive vaccines that protect people against infections, therapeutic cancer vaccines are designed to help the immune system recognise and attack existing cancer cells.

The vaccine is customised using the genetic characteristics of an individual's tumour. Researchers analyse tumour samples to identify specific mutations that could help distinguish cancer cells from healthy cells.

The mRNA is then designed to instruct the body to produce these targets related to tumour, prompting the immune system to recognise and attack the cancer cells. It aims to make the immune response more specific to the patient's cancer rather than targeting all cancer cells.

Six Patients Received The Vaccine

According to reports citing Gintsburg, six patients with melanoma have received the personalised vaccine so far. The first has completed the treatment course, while the second is reportedly halfway through a course involving 10 administrations. Four other patients have also begun treatment.

Russian specialists expect to treat around 20 patients at the Herzen Moscow Research Institute of Oncology by the end of 2026. The country's Health Ministry has reportedly allocated funding for the treatment and follow-up of 120 patients during 2026 and 2027.

Even though the findings are promising, they should not be interpreted as evidence of a cancer cure. The current update concerns one patient with melanoma, a type of skin cancer. Although doctors have reported no new tumour growth during the follow-up period, four months is too short to establish whether the response will last or whether the cancer could return.

There are also currently no results from a large controlled clinical trial that could establish the vaccine's effectiveness, long-term safety or survival benefit.

Outcomes across more patients will be essential to determine whether the treatment can consistently produce similar results.

Personalised cancer vaccines are an active area of research internationally. In October 2026, Moderna and Merck reported positive late-stage trial findings for their experimental personalised mRNA melanoma vaccine, used alongside the immunotherapy drug pembrolizumab (Keytruda).

The trial involved more than 1,100 patients and found a reduction in the risk of melanoma recurrence or death compared with Keytruda alone. However, this is a different vaccine and treatment from Russia's NeoOncovac.

In a major milestone in fetal and paediatric neurosurgery in India, doctors at the All India Institute of Medical Sciences (AIIMS), New Delhi, have performed the country's first open fetal surgery to repair myelomeningocele, the most severe form of spina bifida.

The six-hour procedure was carried out at 25 weeks of pregnancy, in which surgeons were able to repair the baby's spinal defect before birth. The surgery, performed on November 12, entailed repairing a cerebrospinal fluid leak in the lower back while the baby was still in the uterus.

According to AIIMS press release, the operation followed more than five weeks of preparation in multiple disciplines, including detailed fetal imaging, counselling, planning anaesthesia and surgical simulations.

The procedure was done by more than 30 clinicians and nurses from neurosurgery, maternal-fetal medicine, obstetrics, anaesthesia, plastic surgery, radiology and neonatology.

Professor PS Chandra, Head of Neurosurgery at AIIMS, who facilitated the entire surgical execution by the neurosurgery team, said that prenatal surgery could help reduce the incidence of hydrocephalus and Chiari malformations linked with spina bifida.

What Is Myelomeningocele?

Myelomeningocele is an open neural tube defect in which the spinal cord and its protective coverings protrude through an opening in the developing spine. It occurs when the neural tube, which eventually develops into the brain and spinal cord, does not close completely during early pregnancy.

The condition can cause permanent nerve damage, muscle weakness or paralysis, loss of bladder and bowel control, and complications involving the brain and spinal cord. Some affected babies also develop hydrocephalus, a condition in which excess cerebrospinal fluid accumulates in the brain.

In many cases, surgery to close the spinal defect is performed after birth. However, exposure of the spinal cord to the surrounding amniotic fluid during pregnancy can contribute to further neurological injury.

India continues to face a burden of neural tube defects. A 2024 review of 27 Indian studies estimated their pooled prevalence at 9.46 per 1,000 births.

Is Fetal Surgery The Way Forward?

Unlike conventional postnatal surgery, open fetal repair involves operating on the fetus while it is still inside the uterus. The surgeon accesses the uterus, exposes the affected area of the baby's spine and closes the defect, protecting the exposed spinal cord and its coverings. The aim is to limit further damage to the developing nervous system and improve certain neurological outcomes.

Professor Deepak Gupta, who led the neurosurgical part of the procedure, said, “This establishes an important new capability for fetal care and paediatric neurosurgery in India. In rigorously selected cases, prenatal repair seeks to limit ongoing injury to exposed neural tissue, reduce the subsequent need for cerebrospinal-fluid diversion for hydrocephalus, and improve selected neurological outcomes. It is not a cure, and long-term multidisciplinary care remains essential.”

Evidence for prenatal repair comes from the landmark Management of Myelomeningocele Study (MOMS), an international clinical trial. It found that 40% of children who underwent prenatal surgery required a cerebrospinal fluid shunt by 12 months of age, compared to 82% of those who underwent surgery after birth. Prenatal repair also helped with better motor outcomes and a lower incidence of hindbrain herniation linked with Chiari II.

But fetal surgery comes with its risks. It can increase the chances of premature delivery. It also carries risks related to the opening and subsequent healing of the mother's uterus. It is therefore performed only on carefully selected pregnancies at specialised centres equipped with resources.

Milestone In Fetal Surgery

The AIIMS procedure brings a complex fetal intervention, which is already done in other countries, to India's public healthcare system.

Professor Neena Malhotra, who led the maternal-fetal medicine and obstetric part of the surgery alongside Professor K Aparna Sharma, said, “This accomplishment reflects the collective commitment of an exceptional multidisciplinary team.”

Professor Sharma added, “Fetal intervention in this case is a very well-reasoned and planned decision to optimise the outcomes of both the baby and the mother. The safety of both mother and fetus depends on detailed counselling, high-quality anaesthesia, and coordinated surveillance before and after surgery.”

AIIMS said the procedure was performed free of cost under the Government of India's Janani Shishu Suraksha Karyakram (JSSK). The mother and fetus will continue to receive close monitoring throughout the remainder of the pregnancy, delivery and newborn period.

Can Spina Bifida Be Prevented?

Prevention of spina bifida remains essential even though the option of fetal surgery is available. Neural tube closure takes place within the first 28 days after conception, often before a woman realises she is pregnant.

Adequate folic acid intake before conception and during early pregnancy can significantly reduce the risk of neural tube defects. Preconception counselling, folic acid intake and dietary interventions with folate are therefore important to prevent spina bifida.
