For hand surgeons, in addition to anamnesis and clinical examination, imaging is the essential component in diagnostics and the basis for therapy planning. The focus on the special field of the "hand" and the adjacent joints is limited with regard to the anatomical extent, but with regard to the possible clinical pictures it encompasses the entire range of pathological changes.

Which imaging techniques support the goal of maintaining the functionality of the hand?

The carpal bones can be represented by computer tomography without superimposition. The navicular (scaphoid) should be evaluated sagittally in its longitudinal axis. MRI imaging is useful, for example, when assessing possible ligament injuries or ulnar-carpal complaints on the triangular disc. Stress images prove additional information in the case of of dynamic ligament or joint instabilities.

Imaging with conventional X‑rays is the basis of radiological diagnostics of the hand. In addition, the small structures of the hand and fingers to be assessed must be specifically visualized.

In order to enable precise assessment of the fine and complex structures on the hand in relation to the clinical complaints, close communication of the anamnesis and questions with the radiologist is desirable.

Pregnancy is characterized by increased bone turnover and reversible loss of bone mineral density (BMD) to meet fetal calcium demands. The long-term effect of bone turnover and maternal diet in pregnancy on maternal bone is not well established.

We aimed to determine if an association exists between [1] bone resorption, [2] dietary calcium, and [3] serum 25-hydroxyvitamin D in pregnancy with maternal BMD 5-year postpartum.

This is a prospective, longitudinal study of 107 women recruited to the ROLO low glycemic index dietary intervention trial in pregnancy and followed-up at 13, 28, and 34weeks' gestation and 5years' postpartum. At 13 and 28weeks' gestation, a biomarker of bone resorption, urine cross-linked N-telopeptide of type I collagen (uNTX), was measured. At the 5-year follow-up BMD was measured using dual-energy X-ray absorptiometry. Anthropometry, dietary intakes, and serum 25-hydroxyvitamin D were measured in pregnancy and at 5years. Multiple linear regression, controlling for confounders, wasD 5 years later. These findings could enable the identification of women at risk of declining of BMD in later life, but further research is needed. Adequate dietary calcium should be advised in the antenatal setting to promote lifelong maternal bone health.
Patients with obesity and insulin resistance are at higher risk for arterial and venous thrombosis due to a prothrombotic state.

The present study addressed whether this is reversible by lifestyle intervention and elucidated potential underlying associations.

A total of 100 individuals with impaired glucose tolerance or impaired fasting plasma glucose participated in a 1-year lifestyle intervention, including precise metabolic phenotyping and MRS-based determination of liver fat content as well as a comprehensive analysis of coagulation parameters before and after this intervention.

During the lifestyle intervention, significant reductions in coagulation factor activities (II, VII, VIII, IX, XI, and XII) were observed. Cathepsin Inhibitor 1 Accordingly, prothrombin time (PT%) and activated partial thromboplastin time (aPTT) were slightly decreased and prolonged, respectively. Moreover, plasminogen activator inhibitor-1 (PAI-1), von Willebrand factor (vWF), and also protein C and protein S decreased. Fibrinogen, antithrombie inflammation are potential mechanisms for improvements in hemostasis and could represent future therapeutic targets.
Conduction disturbances requiring permanent pacemaker (PPM) implantation remain a complication following valvular surgery. PPMs confer the risk of infection, tricuspid valve regurgitation and pacing-induced cardiomyopathy. Literature examining PPM placement in mitral valve surgery (MVS) is limited.

Our institutional mitral valve (MV) database was retrospectively reviewed for adult patients undergoing surgery from 2011 to 2019. Patients with preoperative PPM were excluded. Patients were stratified by the receipt of PPM following their index operations. Multivariable logistic regression was performed to determine patient and operative risk factors for PPM. Subgroup analysis was performed on patients who underwent isolated MVS. Kaplan-Meier analysis and a multivariable Cox proportional hazards model were utilized to assess the association between PPM implantation and long-term survival.

A total of 3391 (2991 non-PPM and 400 PPM) patients met the study criteria. Significant predictors of PPM included incread increasing age and concomitant procedures to be risk factors. Receipt of PPM is associated with worse long-term survival but does not independently predict survival. Among patients undergoing isolated MV repair, use of an annuloplasty ring confers a higher risk of PPM compared to an annuloplasty band.
Neuroimaging studies show that nociceptive stimuli elicit responses in an extensive cortical network. Functional near-infrared spectroscopy (fNIRS) allows for functional assessment of changes in oxyhemoglobin (HbO), an indirect index for cortical activity. Unlike functional magnetic resonance imaging (fMRI), fNIRS is portable, relatively inexpensive, and allows subjects greater function. No systematic review or meta-analysis has drawn together the data from existing literature of fNIRS studies on the effects of experimental pain on oxyhemoglobin changes in the superficial areas of the brain.

To investigate the effects of experimental pain on brain fNIRS measures in the prefrontal-cortex and the sensory-motor-area; to determine whether there is a difference in oxyhemodynamics between the prefrontal-cortex and sensory-motor-area during pain processing; to determine if there are differences in HbO between patients with centralized persistent pain and healthy controls.

Studies that used fNIRS to record changes in oxyhemodynamics in prefrontal-cortex or sensory-motor-cortex in noxious and innoxious conditions were included.
