Childhood Maltreatment and Longitudinal Epigenetic Aging
A cohort study involving 1971 children across the US examined the impact of early childhood maltreatment on epigenetic aging, revealing that physical assault and emotional aggression at age 3, and emotional neglect at age 5, are associated with accelerated epigenetic aging. The study utilized data from the Future of Families and Child Wellbeing Study, employing machine learning-derived surrogates to measure epigenetic age acceleration. Findings suggest that maltreatment subtypes differentially affect epigenetic aging, with physical assault linked to positive age acceleration and emotional aggression to negative. The study underscores the lasting biological impact of early maltreatment, mediated by stress-related biological embedding, and highlights the need for further research on the specific effects of maltreatment subtypes.
Intention matters: Success rate of bilateral salpingo-oophorectomy at the time of vaginal hysterectomy for pelvic organ prolapse
The study investigates the success rate of bilateral salpingo-oophorectomy performed during vaginal hysterectomy for pelvic organ prolapse, highlighting that a high pre-operative intention to complete the procedure vaginally significantly increases success rates. The research, conducted through a retrospective chart review of 453 patients, reveals that those consented for extraordinary measures had a higher success rate compared to those consented for the procedure 'if possible'. Factors such as concurrent posterior repair and specific patient histories were associated with higher success rates, although the procedure extended operative time. The findings underscore the importance of surgical intention in achieving successful outcomes.
Intention Matters: Success Rate of Bilateral Salpingo-Oophorectomy at the Time of Vaginal Hysterectomy for Pelvic Organ Prolapse
A retrospective chart review study conducted between 2014 and 2019 at a tertiary medical center evaluated the success rate of bilateral salpingo-oophorectomy during vaginal hysterectomy for pelvic organ prolapse. The study included 453 patients, with a success rate of 57.9% overall. The success rate was significantly higher (93.9%) in patients who consented to extraordinary measures compared to those who consented to the procedure 'if possible' (55%). Factors such as concurrent posterior repair and specific patient histories (e.g., family history of ovarian cancer) were associated with higher success rates. The findings suggest that the surgeon's determination to complete the procedure vaginally significantly impacts the success rate.
Are free ports being used to hide Russian assets?
The Russian war in Ukraine has brought global free ports into focus, raising questions about whether sanctioned individuals are using these valuable goods warehouses to hide assets. Swiss authorities have frozen Russian assets worth CHF 6.3 billion and confiscated 11 properties, but the exact contents and ownership of most free ports remain largely inaccessible to Swiss authorities enforcing sanctions. Free ports, which allow tax-free storage of goods, have been criticized for their secrecy and lack of transparency. Switzerland has tightened controls following scandals, but experts argue that legal loopholes still exist, and recent regulations cannot be applied retroactively. Swiss officials claim current laws are sufficient, but there are calls for further measures to increase transparency and ensure compliance with international sanctions.
Russian war in Ukraine renews pressure on Swiss free ports
The Russian war in Ukraine has intensified scrutiny on Swiss free ports, raising concerns about their use by sanctioned individuals to hide assets. Switzerland has frozen CHF6.3 billion in Russian assets and confiscated 11 properties, but the contents of free ports remain largely inaccessible to authorities. Experts argue that the secrecy of free ports allows some Russian assets to evade sanctions. Despite new regulations, loopholes persist, such as the lack of requirement to establish the ultimate beneficial owner of stored goods. Calls for increased transparency and international cooperation are growing to address these issues.

How the War in Ukraine Affects Swiss Energy Policy
The war in Ukraine and the resulting energy insecurity are prompting countries, including Switzerland, to reassess their energy policies. Switzerland is focusing on securing gas supplies for the upcoming winter, enhancing storage capacity, and diversifying energy sources. The Swiss government is also advancing its Energy Strategy 2050, aiming to phase out nuclear energy and reduce greenhouse gas emissions. Experts emphasize the need for increased renewable energy and cooperation with Europe, given Switzerland's dependency on European infrastructure for energy imports. The geopolitical climate is driving up energy prices, impacting Swiss households.
What the Ukraine war means for Switzerland’s energy policy
The Ukraine war has prompted Switzerland to reassess its energy policy, particularly its reliance on Russian gas. The Swiss government is taking steps to secure gas supplies for the upcoming winter, including procuring gas and storage capacity and waiving anti-trust laws for gas companies. Switzerland's Energy Strategy 2050 aims to phase out nuclear power and reduce greenhouse gas emissions, but the war has accelerated the need for a secure energy supply. Experts emphasize the importance of cooperation with the EU, as Switzerland relies heavily on European infrastructure for energy imports. Rising energy prices are also impacting Swiss households, with significant increases in heating oil and petrol costs.
Impact of the availability of midurethral slings on treatment strategies for stress urinary incontinence: a cost-effectiveness analysis
A cost-effectiveness analysis was conducted to evaluate surgical and non-surgical management strategies for stress urinary incontinence (SUI) in the United States, focusing on the availability of midurethral slings. The study modeled various treatment pathways over a two-year horizon, considering costs and complications. Midurethral slings emerged as the most effective and only cost-effective surgical option, while incontinence pessary and pelvic floor muscle physical therapy were also cost-effective. Other surgical options were not cost-effective, and sensitivity analyses confirmed the robustness of the model.
