Background: The win ratio (WR) is an emerging alternative for reporting composite outcomes, prioritizing clinically significant events such as mortality while incorporating surrogate measures. However, its benefits should be weighed against limitations, particularly the influence of lower hierarchical outcomes. This secondary analysis of the PARAGLIDE-HF trial performed a WR sensitivity analysis using a modified hierarchical composite outcome to assess the utility of WR sensitivity analysis and the efficacy of sacubitril/valsartan versus valsartan.

Article Synopsis
  • The SHAPE trial showed that simple hysterectomy is just as effective as radical hysterectomy in preventing pelvic recurrence in low-risk early-stage cervical cancer, but offers better quality of life and sexual health.
  • A cost-effectiveness analysis using a Markov model over 5 years found that simple hysterectomy costs less ($11,022) and provides more quality-adjusted life years (3.56 QALYs) compared to radical hysterectomy ($12,533 and 3.54 QALYs).
  • The study concluded that simple hysterectomy is a better option overall due to being more cost-effective and yielding a higher quality of life post-surgery.

Passive immunisation with normal human immunoglobulin (NHIG) is recommended as post-exposure prophylaxis (PEP) for higher-risk measles contacts where vaccination is contraindicated. However, the concentration of measles-specific antibodies in NHIG depends on antibody levels within pooled donor plasma. There are concerns that measles immunity in the Australian population may be declining over time and that blood donors' levels will progressively decrease, impacting levels required to produce effective NHIG for measles PEP.

A growing number of older people remain in custody each year resulting in an increasing number of common mental and physical health concerns. No prior evidenced-based targeted psychological interventions support this group of people, and little is known about their needs, current activities, and health-related problems. We addressed these gaps through a project involving older prisoners, prison staff and a project advisory group in one male and one female prison site in the North of England.

Article Synopsis
  • - The PARAGLIDE-HF study examined patients with decompensated heart failure, comparing the effects of sacubitril/valsartan to valsartan on NT-proBNP levels and clinical outcomes.
  • - Among the 466 participants, 33% had de novo heart failure while 67% had chronic heart failure, with no significant differences in NT-proBNP reduction between the two groups after treatment.
  • - The findings suggest that sacubitril/valsartan benefits both de novo and chronic heart failure patients, but there is no significant interaction between the type of heart failure and the medication's effectiveness.

Resistance to clinical malaria takes years to develop even in hyperendemic regions and sterilizing immunity has rarely been observed. To evaluate the maturation of the host response against controlled repeat exposures to P. falciparum (Pf) NF54 strain-infected mosquitoes, we systematically monitored malaria-naïve participants through an initial exposure to uninfected mosquitoes and 4 subsequent homologous exposures to Pf-infected mosquitoes over 21 months (n = 8 males) (ClinicalTrials.

Article Synopsis
  • In the PARAGLIDE-HF trial, sacubitril/valsartan showed better results than valsartan alone in reducing NT-proBNP levels in patients with ejection fraction over 40% after heart failure, but increased instances of symptomatic hypotension (SH) were noted.
  • Of the 466 patients studied, 19.7% experienced SH, with a higher occurrence in those treated with sacubitril/valsartan compared to valsartan, though the timing of SH events was similar in both groups.
  • Patients with SH were more likely to be white, have lower baseline systolic blood pressure, and have a higher left ventricular ejection fraction, but the drug's effectiveness in lowering NT-proBNP

Bandgap is a key property that determines electrical and optical properties in materials. Modulating the bandgap thus is critical in developing novel materials particularly semiconductors with improved features. This study examines the bandgap, highest occupied molecular orbital (HOMO), and lowest unoccupied molecular orbital (LUMO) energy level trends in a metal organic framework, metal-organic framework 5 (MOF-5), as a function of Hammett substituent effect (with the constant σ in the meta-position of the benzene ring) and solvent dielectric effect (with the constant ε).

Background: This study aims to determine (a) if home-based anodal transcranial direct current stimulation (a-tDCS) delivered to the left supramarginal gyrus (SMG) coupled with verbal short-term memory/working memory (vSTM/WM) treatment ("RAM", short for "Repeat After Me") is more effective than sham-tDCS in improving vSTM/WM in patients with primary progressive aphasia (PPA), and (b) whether tDCS effects generalize to other language and cognitive abilities.

Methods: Seven PPA participants received home-based a-tDCS and sham-tDCS coupled with RAM treatment in separate conditions in a double-blind design. The treatment task required participants to repeat word spans comprising semantically and phonologically unrelated words in the same and reverse order.

Background: Retrospective data suggest that the incidence of parametrial infiltration is low in patients with early-stage low-risk cervical cancer, which raises questions regarding the need for radical hysterectomy in these patients. However, data from large, randomized trials comparing outcomes of radical and simple hysterectomy are lacking.

Methods: We conducted a multicenter, randomized, noninferiority trial comparing radical hysterectomy with simple hysterectomy including lymph-node assessment in patients with low-risk cervical cancer (lesions of ≤2 cm with limited stromal invasion).

Background: Osteoarthritis is a significant cause of disability, resulting in increased joint replacement surgeries and health care costs. Establishing benchmarks that more accurately predict surgical duration could help to decrease costs, maximize efficiency, and improve patient experience. We compared the anesthesia-controlled time (ACT) and surgery-controlled time (SCT) of primary total knee (TKA) and total hip arthroplasties (THA) between an academic medical center (AMC) and a community hospital (CH) for 2 orthopedic surgeons.
