In 2023, medication abortion emerged as the most common form of abortion in the United States, reflecting both the convenience and accessibility it offers. With evolving policies, telemedicine provision, and the continued demand for privacy and safety, understanding when and how medical abortion is recommended has become more critical than ever. Abortion in the United States has long been a controversial topic, but the increasing patchwork of state laws has made medical abortion all the more difficult to monitor.

Unlike surgical abortions that take place in clinics, medical abortions tend to occur in private locations with pills prescribed or even ordered over the internet something that makes it difficult to collect data. Throw in the recent round of restrictions and court battles, and researchers, policymakers, and clinicians are left with a distressing void: we just don't know how many medical abortions are being performed, where they are being performed, or what this looks like for women's health.

Although surgical abortion continues as a necessary procedure for specific circumstances, the growth of medication abortion has revolutionized reproductive health care by providing a safe and non-invasive alternative for termination during early pregnancy. This change also highlights the need for proper information, safe access, and quality follow-up care to provide positive health outcomes.

Latest figures from the Guttmacher Institute bring to fore that in the majority of U.S. states with less stringent abortion laws, medication abortion had represented 63% of total procedures offered during 2023. In Wyoming, as an example, 95% abortions were medication-related, with 84% taking the same route in Montana.

Even telemedicine is coming into play: an estimated 10% of medication abortions were provided solely online in states where telemedicine bans did not exist, with some states up to 60%. These trends highlight the importance of preserving and continuing access to abortion pills as an essential part of reproductive health care.

What is A Medical Abortion?

Medical abortion is a non-surgical and non-invasive procedure to end an early pregnancy, usually between 4 and 9 weeks. It uses a two-drug combination: mifepristone, to block progesterone required for continuing the pregnancy, and then misoprostol, which causes uterine contractions to pass the pregnancy. Dr. Rupali Mishra, sonologist and physician at Dr Rupali's Abortion Centre, describes, "Medical abortion is advised if the pregnancy is ensured to be intrauterine and the patient is medically fit".

This involves factors such as severe anemia, bleeding disorders, chronic asthma, or allergies to drugs. She reiterates that availability of follow-up care, such as ultrasound scans to exclude retained products of conception (RPOC), is fundamental to the safe outcome.

When Is Medical Abortion Recommended By The Physician?

Medical abortion is most effective in the early weeks of pregnancy. For pregnancies nine weeks or less, the procedure may frequently be carried out outside of hospital facilities by trained health-care practitioners like gynecologists, nurse-midwives, or certified midwives but outside of US that might be different like in India, No medical method abortions are carried outside the clinic and only at registered MTP centers, by qualified Gynecologist.

However, beyond nine weeks, there is no medical method of abortion that can be carried out in hospitals because risk is greater and complications may arise and only suction evacuation can take place. "Medical abortion is a convenient and non-invasive procedure, hence suitable for patients who value such factors," remarks Dr. Mishra.

The eligibility criteria too are medically oriented. The patient should not have ectopic pregnancy, severe chronic illnesses of heart, kidney, or liver function, or known contraindications to the medication. Written informed consent is legally mandatory in registered MTP centers to confirm understanding and safety of the patient.

Procedure and Follow-Up Care

After administration, patients can suffer from abdominal cramps, pain, and bleeding for 15–20 days. In most instances, there are no complications, but excessive bleeding, severe pain, or incomplete abortion can lead to a suction evacuation procedure. A follow-up ultrasound after about three weeks confirms the uterus is clear, marking the success of the procedure. Dr. Mishra states, "Even with high success rates, routine follow-up is critical to manage potential complications such as infection, prolonged bleeding, or retained tissue."

Safety Precautions and Possible Side Effects

Medical abortion is normally safe, but improper use or self-administration under unsupervised conditions can prove fatal. Heavy bleeding, incomplete abortion, infection, or, in exceptional cases, shock caused by undiagnosed ectopic pregnancy are serious side effects. Dr. Mishra cautions, "Selling abortion pills over the counter without a prescription is illegal and very risky. Medical supervision is a non-negotiable factor to avoid severe complications."

Medical Abortion vs. Surgical Abortion

Knowing the distinction between surgical and medical abortion enables proper patient decision-making. Surgical abortion is instant and appropriate for later gestation or incomplete medical abortion, whereas medication abortion is non-surgical and appropriate for early pregnancy. Both need follow-up for completion assurance and checking for complications.

What Role Telemedicine Play In Successful and Safe Abortion?

Telemedicine has revolutionized access to medication abortion, especially in states with less-restrictive laws. Virtual consultations with trained providers enable patients to get prescriptions and instructions without face-to-face visits, providing greater privacy and ease. However, according to Isabel DoCampo of the Guttmacher Institute, legal safeguards and access need to keep evolving in order to provide safe provision across states.

Medical abortion is safe, effective and becoming increasingly prevalent for the ending of early pregnancy if under qualified medical care.

Eligibility, procedure, and follow-up must be explained to patients so that safety and health can be assured. As reproductive health policy continues to change, maintaining access to safe abortion care—including medication and telemedicine—remains paramount. Open dialogue with objective medical professionals, coupled with adequate support and counseling, continues to be imperative for enabling individuals to make responsible decisions regarding their reproductive well-being.

An international team of researchers has developed an artificial intelligence (AI)-based tool that can significantly improve care for glaucoma -- a leading cause of irreversible blindness worldwide, according to a study published in The Lancet Primary Care journal today.

Researchers led by those from the University of Lisbon in Portugal found that the AI-based screening tool halved the number of unnecessary referrals for glaucoma.

The study, released during the Glaucoma Awareness Week, also showed an accuracy level at par with human eye doctors.

"The high accuracy at excluding people without glaucoma is especially important, as false alarms can lead to unnecessary hospital visits, patient anxiety, and added strain on healthcare services," the researchers said.

According to the researchers, AI-based screening could:

• support earlier detection,
• reduce unnecessary specialist referrals,
• prevent avoidable vision loss,
• can be integrated into routine primary care in a cost-effective way

Key Findings

The study was carried out at a single screening center in Lisbon, Portugal, in 2023.

The experts screened 671 adults aged 55-65 for glaucoma via the AI tool, analyzing images of the eyes. The images were then independently graded by six glaucoma experts.

The AI-tool:

• referred 66 people (9.8 percent) vs 118 referrals (18.0 percent) by the eye doctors,
• diagnosed glaucoma in 40 participants (6.4 percent).
• It correctly identified 78 percent of people who truly had glaucoma, vs 75 percent identified by the eye doctors
• Correctly ruled out the disease in 95 percent of people, vs 91 percent by eye doctors

While modelling studies suggest that screening could substantially reduce glaucoma-related visual impairment and blindness, barriers include the need for specialised diagnostic equipment and trained personnel, particularly in low- and middle-income countries, and the intrinsically low positive predictive value of screening tests.

In such a scenario, the new study showed that "AI may provide a more viable option than population-wide screening", which may seem impractical.

What Is Glaucoma?

Glaucoma is a chronic disease that affects an estimated 80 million individuals globally, according to the World Glaucoma Association.

It is a progressive, degenerative disorder of the optic nerve that produces characteristic visual field damage.

The disease stems from a long asymptomatic phase, resulting in substantial underdiagnosis and delayed treatment.

Even in high-income countries, up to 50 percent of individuals with glaucoma remain undiagnosed, frequently presenting moderate to advanced disease at first detection.

By the year 2040, it is estimated that there will be 22 million individuals worldwide who are blind from glaucoma.

When to see a doctor for glaucoma:

• Vision suddenly gets blurry
• Severe eye pain
• Headache
• Nausea
• Vomiting
• Rainbow-colored rings or halos around lights

In adults, long periods of sleep deprivation has been linked to problems such as weakened immunity, weight gain, depression, and an increased risk of dementia. However, scientists are now paying closer attention to how sleep affects the brain much earlier in life.

However, a new University of North Carolina School of Medicine study suggests that disrupted sleep during early childhood may interfere with key stages of brain development and asl well as increase the risk of developing autism.

Why Sleep Matters For The Developing Brain

Sleep plays a crucial role in helping these synapses form and strengthen. During sleep, the brain organizes and stabilizes these neural connections, shaping the foundation for future brain function. If sleep is repeatedly disrupted during this delicate stage of development, the process may be affected.

Frequent waking or sleep disturbances could interfere with how these neural connections are formed, potentially influencing behavior and cognitive abilities later in life.

The Link Between Sleep And Autism

“The unique effects of sleep loss during development are largely unexplored,” Diering said. “Our data show that babies and children are more vulnerable to the negative effects of sleep disruption. We also found that sleep loss during this crucial period of time can negatively interact with underlying genetic risk for autism spectrum disorder.”

Sleep problems are already known to be common in people with autism. In fact, sleep disruption has been reported in more than 80 percent of individuals with autism spectrum disorder. However, researchers have long debated whether these sleep issues are a cause of the disorder or a consequence of it. Understanding how sleep interacts with brain development could help scientists detect autism earlier and potentially develop new treatment strategies.

Studying Sleep Disruption In Early Life

In earlier work conducted in 2022, researchers examined how sleep disruption during early life might interact with genetic factors linked to autism. Using mouse models, they disrupted sleep during the third week of life, a developmental stage roughly comparable to ages one to two in humans.

The study found that sleep disruption during this period produced long lasting behavioral changes. Male mice that were genetically vulnerable to autism showed deficits in social behavior later in life. These results suggested that sleep disruption during critical stages of development may interact with genetic risk factors in ways that shape long term behavior.

Younger Brains Respond Differently To Sleep Loss

To investigate further, researchers studied how developing and adult mice respond differently to sleep deprivation.

Using specially designed housing systems equipped with sensitive sensors, scientists tracked the animals’ breathing and movement. This allowed them to determine when the mice were awake and when they were asleep.

The researchers observed that adult mice were able to compensate for lost sleep. After experiencing sleep deprivation, the adults increased their sleep later during their normal active period. This process, known as sleep rebound, allowed them to recover some of the lost rest.

Younger mice behaved very differently. They showed no sleep rebound at all, meaning they did not compensate for the sleep they had lost. This finding suggests that younger brains may be far more vulnerable to the effects of sleep disruption.

The consequences were also visible in cognitive performance. Sleep deprived young mice performed poorly on learning and memory tasks, while adult mice were significantly more resilient after losing sleep.

Changes At The Level Of Brain Synapses

The results showed that sleep deprivation in young mice significantly altered the formation of synapses. These changes were not seen in adult mice. “This now provides one of the largest and most comprehensive datasets to examine the molecular effects of sleep loss across the lifespan,” Diering said.

Potential Future Treatments

“Development is not something that one can go back and do again,” Diering said. “Sleep is important for the entire life and especially during development. Understanding what we know now will place greater emphasis on understanding sleep issues in ASD and could lead to an important therapeutic avenue to treat ASD and other developmental conditions.”

The findings highlight an important message for parents and caregivers. During early childhood, healthy sleep patterns may play a critical role in shaping the brain for years to come.

Using amphetamines, cocaine and cannabis can significantly increase your risk of having a brain stroke particularly among younger adults, according to a new University of Cambridge analysis

The findings highlight how recreational drug use may contribute to a preventable health risk, especially among people under the age of 55.

Megan Ritson, a stroke genetics researcher at the University of Cambridge and lead author said the results provide strong evidence linking certain drugs to stroke risk.

“These findings provide compelling evidence that drugs like cocaine, amphetamines, and cannabis are causal risk factors for stroke,” Ritson noted.

A stroke occurs when blood flow to part of the brain is interrupted. This can happen when a blood vessel becomes blocked by a clot, known as an ischemic stroke, or when a blood vessel bursts and causes bleeding in the brain, known as a hemorrhagic stroke. Both types can lead to serious brain damage and can be life threatening.

Amphetamines Associated With The Highest Risk

When researchers combined data from eight previous studies, they found that recreational amphetamine use was associated with more than double the risk of stroke across all adult age groups. For individuals under the age of 55, the increase was even greater. In this group, amphetamine use was linked to nearly triple the risk of stroke compared with people who do not use the drug.

Across all age groups, the analysis found that amphetamine use increased the risk of ischemic stroke by 137 percent and hemorrhagic stroke by 183 percent. These figures reflect relative risk, meaning the probability of stroke is higher among users compared with non users.

Cocaine Shows A Similar Pattern

The analysis showed that cocaine use nearly doubled the risk of stroke of any kind and more than doubled the risk of hemorrhagic stroke. Additional genetic investigations were conducted alongside the main analysis to better understand whether the relationship might be causal rather than simply linked to other lifestyle factors.

Eric Harshfield, a genetic epidemiologist at the University of Cambridge, said the findings suggest the drugs themselves may play a direct role. “Our analysis suggests that it is these drugs themselves that increase the risk of stroke, not just other lifestyle factors among users,” Harshfield said.

Cannabis Linked To Smaller But Significant Risk

Among people under the age of 55, cannabis use was linked to a 14 percent increase in stroke risk. Although the increase is lower than that associated with stimulant drugs, researchers say it remains important because cannabis is widely used.

Opioids Showed No Clear Association

A Preventable Health Risk

The researchers also note that many of the studies included in the analysis relied on participants reporting their own drug use. Because of this, other lifestyle factors could potentially influence the results. Further research will be needed to better understand the biological mechanisms involved and how different patterns of drug use may affect stroke risk. Still, scientists say the evidence now available provides an important foundation for future public health strategies.

“These findings give us stronger evidence to guide future research and public health strategies,” Ritson said.
