Unlabelled: Ischemia modified albumin (IMA) is a new biochemical marker of ischemia. IMA levels rise in patients who develop ischemia during percutaneous coronary intervention (PCI). It is unclear whether IMA elevations correlate with PCI variables. The possible prognostic value of post-PCI IMA elevation has not yet to be studied.
Methods: We studied 60 patients (mean age 61 years; 51 male) who underwent successful elective single-vessel PCI for the management of stable angina pectoris. IMA levels were measured and compared with PCI variables and target lesion revascularization rate. The median post-PCI follow up is 46 months (CI 44.6 to 47.7).
Results: We found that the only variable related to post-PCI IMA levels was periprocedural dissection of target vessel (147.6 vs. 141.1 kU/l, p=0.035). No correlation between high and low balloon inflation pressure (143.6 vs. 141.6 kU/l, p=0.64), short and long inflation pressure (141.5 vs. 143.6 kU/l, p=0.17), with and without stent placement (143.7 vs. 141.3 kU/l, p=0.93) was found. IMA level more then 130 kU/l was associated with higher frequency of target lesion revascularization at nearly 4-years follow-up (p=0.026).
Conclusion: Post-PCI IMA elevation is associated with higher target lesion revascularization.

Chemical proteomics has advanced small molecule ligand discovery by providing insights into protein-ligand binding mechanism and enabling medicinal chemistry optimization of protein selectivity on a global scale. Mass spectrometry is the predominant analytical method for chemoproteomics, and various approaches have been deployed to investigate and target a rapidly growing number of protein classes and biological systems. Two methods, intact mass analysis (IMA) and top-down proteomics (TDMS), have gained interest in recent years due to advancements in high resolution mass spectrometry instrumentation.

Background: The development of a cost-effective and easily applicable fixation method to address all components of hallux valgus (HV) surgery is of great importance to the field. This study aims to assess the clinical efficacy of an alternative fixation method that combines the advantages aspects of commonly used distal osteotomy techniques and evaluate its level of applicability in the treatment of mild and moderate HV cases.
Methods: The retrospectively designed study was conducted at Adana City Training and Research Hospital, Adana, Türkiye.
Navigating diabetes care inequities: an observational study linking chronic care model's structural elements to process and outcomes of type 2 diabetes care in Belgium.

Department of Sociology, Vrije Universiteit Brussel, Brussels, Belgium.
Background: Although the Chronic Care Model (CCM) provides the essential structural components of practice organisation to deliver high-quality type 2 diabetes (T2D) care, little is known about which of its elements are most important, and the extent to which it may reduce social inequities in the quality of T2D care. This study aims to assess the association between the implementation of CCM's structural elements and the quality of T2D care processes and outcomes in Flanders (Belgium), paying specific attention to differences by patients' socioeconomic vulnerability.
Methods: We developed a longitudinal database combining information on primary care practices' CCM implementation, with individual-level health insurance and medical lab data.

Background: Acute ischemic stroke (AIS) is a prevalent and challenging neurological condition associated with high mortality and morbidity rates. This study aimed to evaluate the therapeutic efficacy of repetitive transcranial magnetic stimulation (rTMS) combined with ginkgo diterpene lactone meglumine injection (GDLMI) on cognitive and neurological function recovery in patients with AIS.
Methods: A total of 120 patients with AIS, admitted between January 2021 and January 2022, received rTMS combined with GDLMI after admission.
