The European Food Safety Authority sets a reference intake of 0.83 grams of protein per kilogram of body weight a day for adults. Athletes, some older people and those with chronic kidney disease need different evidence and, in some cases, clinical guidance.
The World Health Organization advises moving to the coolest room at night and using air conditioning with a fan when available during a heatwave. Fans, bathing and bedding serve different purposes, and no single bedroom temperature suits every sleeper or climate.
UC San Diego researchers reported on July 8, 2026, that a surgeon remotely controlled a humanoid robot during two gallbladder operations on pigs. The study showed technical feasibility, but human bedside assistance, repeated recalibration and sterility problems remain barriers to clinical use.
A 2020 network meta-analysis of 125 trials found that several desensitizing toothpaste ingredients reduced pain from exposed dentin. Brief pain may fit dentin sensitivity, but lasting or spontaneous pain requires dental assessment because decay, a crack and pulp inflammation can feel similar.
WHO postnatal guidance calls for partners, families and health workers to support both feeding and maternal well-being after birth. Practical help can reduce the burden, while pressure to breastfeed is associated with worse anxiety, stress and birth-trauma symptoms.
The World Health Organization said in June 2026 that contaminated food causes an estimated 866 million illnesses and 1.52 million deaths each year. Most suspected cases cannot be identified from symptoms alone, but dehydration, bloody diarrhea and an inability to keep liquids down require prompt medical assessment.
Updated United Kingdom health guidance directs parents to swallowing, diaper output and weight gain when assessing whether a breastfed newborn is getting enough milk. A single pumping session records what the pump removed, while the baby's condition and feeding pattern determine whether clinical assessment is needed.
Researchers in South Korea and the United States reported two manufacturing advances for stretchable electronics in 2026. One kept liquid-metal conductors working under repeated strain, while the other put a dense computing array on a stretchable patch, but neither study tested a finished implant in people.
A systematic review published in January 2026 found that generative AI increased the volume, speed and perceived credibility of health misinformation in the available studies. Clinicians can use the same tools to draft public information, but the evidence and professional guidance leave accuracy, privacy and disclosure with the person who publishes it.
A 2026 laboratory study found that freeze-dried platelet-rich plasma could be rehydrated after storage, but it did not test pain relief or tissue repair in patients. Published human evidence for the freeze-dried product remains too limited to borrow treatment claims from conventional platelet-rich plasma.
A 2024 New Zealand study linked pressure to breastfeed with higher anxiety, stress and birth-trauma symptoms four weeks later. A separate systematic review found limited but generally favorable evidence for partner help, including household and childcare work.
A July 30, 2026 Coldcard advisory showed how a random-number integration error could remain hidden while security-sensitive outputs still looked valid. The same failure pattern matters in health information systems that generate pseudonyms and SMART on FHIR authorization secrets.
The World Health Organization’s five food safety steps give households a common framework for handling meals during hot weather. The system controls contamination, cooking and storage rather than relying on a food’s appearance or smell.
The World Health Organization’s June 2026 update estimated 866 million foodborne illnesses worldwide in 2021. Its food-handling guidance limits cooked food to two hours at room temperature and emphasizes separation, clean equipment and safe water.
A Cochrane review of 71 trials found that home bleaching whitened adult teeth over two weeks to six months, though the evidence was low to very low certainty. Peroxide changes pigments inside natural teeth, while whitening toothpaste mainly removes surface stains and can neither bleach restorations nor correct every discoloration.
A 2024 colorectal surgery guideline recommends dietary and behavioral changes as first-line care for symptomatic hemorrhoids. Medication may ease some symptoms, but persistent bleeding, severe pain or prolapse can require examination and a procedure.
A 2025 systematic review found that non-benzodiazepine muscle relaxants improved several short-term outcomes in acute low back pain compared with placebo. Adverse events were more frequent, while a broader review found that evidence for most back-pain treatments remained uncertain.
Decay, infection, cysts and damage to a neighboring tooth can make wisdom-tooth removal appropriate. For symptom-free, disease-free impacted teeth, evidence does not establish that routine removal is better than monitoring.
