    Unusual bleeding during and after pregnancy

    When should pregnant women be concerned? Awareness of the dangers associated with abnormal bleeding during pregnancy and after childbirth can be lifesaving for both women and their babies.

    Dr. Mzuvele Archwell Hlabisa, an obstetrician and gynaecologist at Netcare Kingsway Hospital, emphasizes that while many people are unaware that over a third of pregnant women may experience bleeding for various reasons, it is crucial to determine the exact cause.

    "Although some bleeding is normal in the postpartum period, excessive bleeding can be life-threatening. It is often difficult for women to discern if their bleeding is normal or not, but a good rule of thumb is to have any bleeding during pregnancy checked by a healthcare professional," says Dr. Hlabisa.

    He notes that around 35% of women experience bleeding in the first trimester. "As the pregnancy progresses, the likelihood of bleeding decreases, so it’s reassuring when women reach the mid-trimester, from 13 to 28 weeks of gestation."

    Bleeding could indicate a miscarriage or a threatened miscarriage, and severe pain with bleeding could be related to placental abruption, a serious condition where the placenta prematurely separates from the womb. These conditions require immediate medical assessment.

    Spotting In early pregnancy, some women may experience spotting, known as implantation bleeding, when the embryo implants in the uterine wall. ...Read full article

    Study Finds Reminders Can Prevent Age-Related Memory Decline
    A recent study from the University of Texas at Arlington reveals that setting reminders can help eliminate certain age-related memory declines. The research offers an important advancement in addressing cognitive challenges faced by older adults, particularly in prospective memory, which involves remembering to complete tasks at the appropriate time, such as taking medication or attending appointments.

    Prospective memory is crucial for everyday living and maintaining independence, especially for aging individuals. Failure to recall these future-oriented tasks can have serious consequences, as previous studies have shown that this type of memory tends to weaken with age.

    Hunter Ball, an associate professor of psychology at UTA and lead author of the study, collaborated with psychologists from Arizona State University to conduct two experiments. These experiments tested the prospective memory of younger and older adults under various conditions, with or without the use of reminders. Participants were tasked with remembering specific actions while engaging in ongoing activities, with their performance assessed in both high-load (more tasks) and low-load (fewer tasks) scenarios.

    In the first experiment, participants were asked to remember specific tasks, such as responding to particular words, with some receiving on-screen reminders. Results showed no significant age-related decline in prospective memory under low load without reminders. However, in high-load conditions, both younger and older adults showed similar improvement when reminders were used, suggesting that reminders help reduce cognitive strain by offloading the need to rely entirely on internal memory.

    The second experiment introduced more complex tasks that required participants to recognize broader categories, like animals or fruits, rather than specific words. Without reminders, older adults had more difficulty remembering these tasks in high-load conditions. However, the performance gap between younger and older adults disappeared when reminders were available, underscoring the potential of reminders to mitigate memory challenges in older adults, especially for cognitively demanding tasks.

    According to Ball, reminders are particularly effective for older adults because they tend to check them more frequently when faced with high cognitive demands. This compensatory behavior helps older adults manage tasks that might otherwise overwhelm their internal memory resources.

    The implications of this study reach beyond the laboratory. Prospective memory is essential in real-world settings, and with an aging population, finding practical solutions to memory challenges is increasingly important. The researchers highlight that digital tools, such as smartphone apps, personal assistants like Amazon Alexa, or simple reminder notes, can be valuable aids for older adults in managing their daily responsibilities and maintaining their independence.

    “This study shows that cognitive offloading, like using reminders such as cell phone calendars, can effectively reduce memory challenges in older adults,” said Ball. “Although our study was conducted in a controlled environment, these findings are easily applicable in everyday life, providing a simple and effective way to alleviate the burden of prospective memory issues in older adults."

    Cholera Crisis Deepens Amid Ongoing Conflict in Sudan
    Sudan's health ministry has reported over 430 cholera-related deaths in the past month, as the country remains engulfed in civil war. The number of infections has surged to approximately 14,000. The ministry emphasized its efforts to combat the cholera outbreak in affected states, but the ongoing conflict complicates treatment delivery. US special envoy for Sudan, Tom Perriello, estimates that around 150,000 people have lost their lives since the war began in April 2023. Mdecins Sans Frontires (MSF) has highlighted significant challenges in their humanitarian response due to obstructions from both warring factions, resulting in inadequate assistance for those in need. In a recent report, MSF noted the collapse of Sudan's health system, with alarming rates of maternal and neonatal mortality. The conflict stems from a power struggle between the army and the Rapid Support Forces (RSF), which has led to what the UN describes as one of the worst humanitarian crises globally. More than nine million people have been displaced, and there are growing concerns of widespread famine due to failed agricultural activities. Warnings of potential genocide against non-Arab communities in Darfur have also emerged. Cholera, a fast-spreading and highly infectious disease, can lead to severe dehydration and death if not treated promptly. While it is relatively easy to treat, immediate care is crucial. Health Minister Haitham Mohammed Ibrahim declared a cholera outbreak in mid-August, exacerbated by heavy rainfall, flooding, and overcrowding in displacement camps. MSF emergency coordinator Esperanza Santos described the situation as a "perfect storm" for cholera proliferation. In some regions, schools, markets, and shops have been ordered to close to mitigate the disease's spread. MSF reported 114 maternal deaths in South Darfur alone between January and August, with many children facing starvation. The organization warned that the conditions in South Darfur likely reflect a broader crisis across isolated, war-torn areas of Sudan. Dr. Gillian Burkhardt, MSF's sexual and reproductive health manager in South Darfur, expressed deep concern, stating, "This is a crisis unlike any other I have seen in my career."

    Patient Faces Ongoing Struggles After Ozempic Treatment
    Dana Filmore was initially terrified of taking Ozempic due to her fear of needles. The thought of injecting herself in the stomach with this diabetes medication seemed daunting. However, after her antidiabetic pills failed to adequately manage her blood sugar, her doctor recommended Ozempic, which is FDA-approved for treating Type 2 diabetes. Filmore, a 55-year-old grandmother from Columbus, decided to take the plunge. She began using Ozempic but stopped six months ago due to troubling side effects. Now, three years later, she has been diagnosed with gastroparesisstomach paralysiswhich can be a potential side effect of the drug. Since discontinuing the injections, she has struggled with eating and digestion. Gastroparesis affects the stomachs ability to contract, causing food to remain in the stomach longer than normal. This often leads to severe symptoms such as vomiting and diarrhea. Filmores experience highlights the serious risks associated with Ozempic, raising important questions about the medication's long-term effects.

    Musk Advocates for Accessibility of GLP-1 Drugs Amid High Prices in the U.S.
    Recent treatments that mimic a hormone regulating appetite and blood sugar have proven highly effective for obesity and type 2 diabetes management. The most notable GLP-1 medications available are Ozempic and Wegovy, both developed by Danish pharmaceutical company Novo Nordisk. Elon Musk recently shared on X, the social media platform he owns, that addressing obesity significantly lowers the risk of related diseases, particularly diabetes, and enhances overall quality of life. He emphasized the need to make appetite-suppressing medications accessible to everyone. His comments came in response to Senator Bernie Sanders, who noted that generic drug manufacturers claim they could offer these medications for less than $100 a month. Currently, the list price in the U.S. for Ozempic is $968.52 and for Wegovy, its $1,349.02. In contrast, these drugs are much more affordable in other countries, with Ozempic priced at just $59 in Germany and Wegovy at $92 in the U.K. Musk remarked, I dont often agree with Bernie on many issues, but I do on this one. During a recent Senate hearing, Senator Sanders questioned Novo Nordisk CEO Lars Fruergaard Jrgensen about the companys pricing strategies for these high-demand drugs in the U.S. He highlighted that since 2018, Novo Nordisk has earned $50 billion from Ozempic and Wegovy, with a staggering 72% of that revenue generated from U.S. sales. Sanders stated, In other words, the United States is Novo Nordisks cash cow for Ozempic and Wegovy. He even quoted Musks tweet, acknowledging, Mr. Musk is right.

    Global Rise in Short-Sightedness Among Children Linked to Lockdowns and Screen Time
    A global analysis reveals that children's eyesight is deteriorating, with one in three now experiencing short-sightedness, or myopia. Researchers suggest that the Covid lockdowns contributed significantly to this decline, as children spent more time on screens and less time outdoors. Myopia is becoming a pressing global health issue, with projections indicating that millions more children will be affected by 2050. The study highlights alarming rates in Asia, where 85% of children in Japan and 73% in South Korea are short-sighted, along with over 40% in China and Russia. In contrast, countries like Paraguay and Uganda report some of the lowest levels of myopia, around 1%, while the UK, Ireland, and the US have rates close to 15%. Published in the British Journal of Ophthalmology, the study analyzed data from over five million children and teenagers across 50 countries on all six continents. The findings show that short-sightedness has tripled from 1990 to 2023, now affecting 36% of children, with a particularly significant spike observed following the pandemic. Myopia typically begins in primary school and can worsen until the eye stops growing around the age of 20. Factors influencing its prevalence include geographic location, genetics, and educational practices. In East Asia, where formal education often begins as early as age two, children spend more time focusing on books and screens, straining their eye muscles and increasing the risk of developing myopia. In contrast, in Africa, where schooling generally starts at ages six to eight, the prevalence of myopia is seven times lower than in Asia.

    Junk Food Advert Bans on Public Transport to Combat Childhood Obesity
    Junk food advertisements will be prohibited on select bus and train services as part of a new initiative aimed at reducing childhood obesity. The North East joins nine other regions in this effort, banning unhealthy food promotions on the Metro and bus services. Mayor of the North East, Kim McGuinness, emphasized that "enough is enough," labeling the targeting of children with such adverts as "predatory." The AdEnough campaign, initiated by chef Jamie Oliver, supports this move, stating it is a "vital step" due to the constant bombardment of unhealthy food messaging aimed at children. This ban will be adopted by mayors in Greater Manchester, Liverpool, North Yorkshire, South Yorkshire, West Yorkshire, Cambridgeshire and Peterborough, and the West Midlands. Recent reports from Newcastle City Council reveal that 11% of reception-age children and 26% of those in year six in the North East are classified as obese. National statistics indicate that over one in five children in England are overweight or obese by the time they start primary school, with that figure rising to more than one in three by the time they finish. McGuinness stated that this pledge sends a strong message to junk food companies and aligns with broader national efforts to curb junk food advertising. The implementation will follow her plans to regain control of buses from private operators. Greater Manchester Mayor Andy Burnham remarked that young people deserve "the best possible start in life," commending the initiative as a challenge to junk food corporations. The ban is already operational on Londons tubes and buses. Jamie Oliver praised the mayors for their proactive stance, calling it a "much-needed and vital step towards creating healthier, happier communities" in the UK, though he noted that more work is needed to address unhealthy food messaging. Additionally, it was recently announced that online junk food adverts will be banned starting next year, alongside restrictions on TV advertisements before 9 PM, effective from October 2025.
