Background: Stereotactic radiosurgery (SRS) is effectively used for treating various cerebrovascular diseases, including arteriovenous malformations. As image-based surgery is the gold standard technique in SRS, the quality of stereotactic angiography images greatly influences the surgical approach for cerebrovascular diseases. Despite several studies in the relevant literature, research on auxiliary devices, including angiography indicators used for cerebrovascular disease surgeries, is limited. Thus, the development of angiographic indicators may provide meaningful data for stereotactic surgery.
Methods: A centerline was drawn, and a guideline was attached such that the "+" and "X" centers of the existing angiography guide indicator intersect. Further, a guideline wire connecting "+" and "X" was fixed using a tape. Based on the presence or absence of the guide indicator, angiography anterior-posterior (AP) and lateral (LAT) images were taken 10 times each, and statistical analysis was performed.
Results: The average and standard deviation of the conventional AP and LAT indicators were 10.22 ± 0.53 mm and 9.02 ± 0.33 mm, and those of the developed AP and LAT indicators were 10.3 ± 0.57 mm and 8.92 ± 0.23 mm, respectively.
Conclusions: The results confirmed that the use of the lead indicator developed in this study provides higher accuracy and precision compared to that of the use of the conventional indicator. Furthermore, the developed guide indicator may provide meaningful information during SRS.

Background: Maintaining the connection between skeletal muscle fibers and the surrounding basement membrane is essential for muscle function. Dystroglycan (DG) serves as a basement membrane extracellular matrix (ECM) receptor in many cells, and is also expressed in the outward-facing membrane, or sarcolemma, of skeletal muscle fibers. DG is a transmembrane protein comprised of two subunits: alpha-DG (α-DG), which resides in the peripheral membrane, and beta-DG (β-DG), which spans the membrane to intracellular regions.

Background: Predicting burn-related mortality is vital for family counseling, triage, and resource allocation. Several of the burn-specific mortality prediction scores have been developed, including the Abbreviated Burn Severity Index (ABSI) in 1982. However, these scores are not tested for accuracy to support contemporary estimates of the global burden of burn injury.

Ovarian stimulation (OS) is a crucial component of clinical IVF treatment that strongly influences outcomes. As such, it is useful to understand the indicators for successful OS during IVF. As OS leads to multiple follicular recruitment, it can be quantified as number of oocytes retrieved.

Background: Up to 23% of breast cancer patients recurred within a decade after trastuzumab treatment. Conversely, one trial found that patients with low HER2 expression and metastatic breast cancer had a positive response to trastuzumab-deruxtecan (T-Dxd). This indicates that relying solely on HER2 as a single diagnostic marker to predict the efficacy of anti-HER2 drugs is insufficient.

Background: The COVID-19 pandemic has highlighted the need for more effective immunization programs, including in limited resource settings. This paper presents outcomes and lessons learnt from a COVID-19 vaccination campaign (VC), which used a tailored adaptive strategy to optimise vaccine uptake in the Boeny region of Madagascar.
Methods: Guided by the Dynamic Sustainability Framework (DSF), the VC implementation was regularly reviewed through multi-sectoral stakeholder feedback, key informant interviews, problem-solving meetings, and weekly monitoring of outcome indicators to identify and apply key adaptations.
