A study in Bangladesh found that treating children with severe pneumonia at local, first-level facilities instead of hospitals resulted in higher proportions being treated correctly. The modified guidelines allowed for local treatment with referral to hospital only for the most severe cases.
The study found a significant decrease in child pneumonia mortality rates after introducing improved oxygen systems, with a 35% lower risk of death. The cost-effectiveness of this system was also compared to other public-health interventions, with favorable results.
A new study found that combining two commonly used blood pressure medications, ACE inhibitors and ARBs, reduces urine protein levels more than taking either medication alone. However, it also causes more kidney damage and a higher risk of death among high-risk patients.
A randomized controlled trial found that high-dose tirofiban improved ST-segment resolution and clinical outcomes for STEMI patients undergoing primary coronary angioplasty. The study showed lower overall mortality and less urgent repeat PCI in the tirofiban group.
Indonesia has experienced the most human cases of bird flu and one of the highest mortality rates due to the disease. Development of better diagnostic methods and improved case management could lead to faster treatment with antiviral drugs, decreasing mortality.
A retrospective analysis of postmenopausal women with early-stage breast cancer found that previous use of hormone replacement therapy (HRT), hormone-receptor positivity, and treatment with anastrozole versus tamoxifen were associated with joint symptoms. Obesity was also linked to increased joint symptoms in these patients.
A UK study found that financial incentives reduced inequalities in clinical care between affluent and poor areas. Practices serving poorer populations improved their performance over time, narrowing the gap with more affluent areas.
A study of quarter of a million patients found epidural anaesthesia to be safe for intermediate to high-risk surgery, but only slightly improving survival rates. The procedure offers better postoperative pain relief and reduces surgical stress response.
A phase I/II study found that intrabone administration of unrelated cord-blood cells increased the number of patients who could receive hematopoietic stem-cell transplantation. The technique reduced the incidence of graft-versus-host disease, a common complication of allogeneic transplants.
The Lancet recommends allowing newborn infants to participate in multiple clinical studies with their parents' consent, provided it does not compromise care or safety. This would strengthen the evidence base for medical care of newborn infants and balance ethical concerns.
A large cohort of Danish children with up to 28 years of follow-up showed that death after febrile seizures is extremely rare. Children who had simple febrile seizures had mortality similar to the general population, but those with complex febrile seizures had a two-fold higher risk of death within two years.
To reduce HIV transmission, radical behavioral change is necessary, involving a range of strategies including increasing HIV knowledge, decreasing risky behaviors, and providing access to treatment. The authors emphasize the need for sustainable commitment and proper resources to implement these prevention strategies.
Researchers argue that structural approaches can significantly reduce HIV risk and vulnerability, particularly in addressing gender inequality and economic dependence. Examples of successful initiatives include needle exchange programmes and empowering sex workers to take control of their own health.
Researchers recommend using prophylactic antiretroviral (ARV) drugs to reduce infectiousness among HIV-positive individuals. Male circumcision is also shown to significantly reduce the risk of HIV transmission. Providing contraception for HIV-positive women can further prevent mother-to-baby transmission and unintended pregnancies.
Most countries are not effectively targeting their HIV resources, and new strategies must be implemented to improve prevention interventions. The limited data available indicate that many countries are focusing their prevention resources where the epidemics are concentrated, leading to low coverage rates for effective interventions.
The Lancet Series on HIV Prevention calls for confident and unified leadership to overcome barriers to effective HIV prevention. The authors urge investment in operational research, HIV vaccine development, and capacity building for national authorities to deliver universal access.
The Lancet series highlights the importance of combination prevention approaches, combining behavioural, medical, and structural strategies. The authors warn that global prevention efforts are woefully insufficient, with fewer than 10% of individuals at risk receiving key services.

The study showed a 98% correct treatment decision rate for telemedicine versus 82% for telephone consultations.
A study of 883 treatment-naïve HIV patients found that atazanavir/ritonavir once daily was as effective as lopinavir/ritonavir twice daily in reducing viral load and increasing CD4 cells. The once-daily regimen had less gastrointestinal toxicity but a higher rate of hyperbilirubinemia, supporting its use as a first-line treatment option.
A randomized controlled trial found that removing H. pylori bacteria from stomachs of post-operative stomach cancer patients can significantly reduce the risk of stomach cancer redeveloping. The study showed a two-thirds reduction in metachronous gastric cancer development between eradication and control groups.
Researchers analyzed 1173 cases of community-acquired pneumonia and found that flu vaccination was not associated with a reduced risk. The study suggests that the vaccine may not be effective in reducing influenza infection in elderly individuals at risk of pneumonia.
A recent study found that infants conceived through assisted fertilization had similar birth weights and gestational ages as those conceived naturally. However, they were more likely to experience perinatal deaths if their mother had previously struggled with infertility. The researchers suggest that the underlying causes of infertilit...
Researchers found that PBT2 improves two indicators of executive function in Alzheimer's patients and reduces amyloid beta levels in the spinal fluid. The study suggests that PBT2 may be a promising treatment for improving cognitive performance in early-stage Alzheimer's disease.
The report found that paediatric-oncology care varied substantially between countries, with access to care or management extremely poor in seven out of ten nations. The five-year survival rate was as low as 5% in some countries, while higher rates were observed in those with greater health expenditure and infrastructure.
A new study published in The Lancet suggests that dementia prevalence in less developed countries may be significantly higher than initially estimated. The study used a unique diagnostic method to assess dementia cases in 15 sites across 11 countries, revealing higher prevalence rates compared to conventional criteria.
The HIV/AIDS epidemic affects nearly 2 million people in Latin America and the Caribbean, with most transmission through unprotected sex. The region faces unique challenges due to socio-economic disparities, homophobia, and lack of access to healthcare and education.
A regimen of extended-dose nevirapine reduced the risk of infants contracting HIV via breastfeeding by 20% at six months of age. The study found a significant reduction in HIV transmission at six weeks of age, but access to safe replacement feeding remains crucial.
A recent study estimates that if couples stop using condoms, HIV incidence could easily quadruple over 10 years. The risk of transmission from effectively treated patients is low but non-zero, and transmission risks are higher in male homosexual partnerships.
Studies show a significant increase in life expectancy among HIV-positive individuals on combination antiretroviral therapy (cART), with total life expectancy rising from 56.1 years to 69.4 years between 1996-99 and 2003-05. However, patients treated late in the course of their infection have worse life expectancy.

Despite clearing associated brain plaques, immunized patients did not show improved survival or increased time to severe dementia.
A comprehensive study of 31 countries found significant variations in cancer survival rates, with the US and Europe experiencing lower survival rates compared to other regions. The study reveals a racial gap in cancer survival between black and white populations in the US, with blacks facing a 7-14% lower survival rate.
A combination treatment with methotrexate and etanercept improves remission rates by 50% and radiographic non-progression by 21% compared to methotrexate alone. The treatment also increases the ability of patients to remain in employment, with significant implications for employers and society.
A study found that abatacept reduced flare events and improved symptoms in children with juvenile idiopathic arthritis, but its design raised questions about its true effectiveness. The treatment was well-tolerated, but the study's limitations highlighted the need for further research to establish its role in treating this condition.
Researchers found that intermittent preventive treatment (IPT) for malaria lowers anaemia prevalence and improves classroom attention in children aged 5-18 years in Western Kenya. The IPT reduced the occurrence of malaria infection by half and lowered anaemia rates among children.
A phase III study found that pegylated interferon alfa-2b significantly improved recurrence-free survival in stage III melanoma patients, with a median treatment duration of one year. The treatment reduced the risk of recurrence by 18% and was associated with serious adverse events such as fatigue, liver toxicity, and depression.
