Article Synopsis
  • The study aimed to evaluate the impact of short stress-coping interventions (cardiac biofeedback, mindfulness, and positive psychology) on the OSCE performance of medical students.
  • Despite no significant improvement in academic scores for any intervention group compared to the control, students reported a more positive perception of their performance after the interventions.
  • Conclusively, these brief interventions did not enhance students' actual academic performance during the OSCE, though they influenced their self-assessment.

This single-center retrospective study was designed to evaluate the use of basiliximab as an alternative rescue maintenance immunosuppression in situations where standard maintenance immunosuppression is not tolerated after a pancreas transplant. All pancreas transplants performed between January 11, 2006, and January 6, 2022, were reviewed. All recipients received rabbit antithymocyte globulin (rATG) induction with tacrolimus + sirolimus maintenance for simultaneous pancreas and kidney (SPK) and additional low-dose mycophenolic acid for pancreas transplant alone (PTA).

Meditation is a mental training approach that can improve mental health and well-being in aging. Yet the underlying mechanisms remain unknown. The Medit-Ageing model stipulates that three mechanisms - attentional, constructive, and deconstructive - upregulate positive psycho-affective factors and downregulate negative ones.

Background: Shorter telomeres are associated with increased risk of cognitive decline and age-related diseases. Developing interventions to promote healthy aging by preserving telomere integrity is of paramount importance. Here, we investigated the effect of an 18-month meditation intervention on telomere length (TL) measures in older people without cognitive impairment.

There is a renewed interest in taking phenomenology seriously in consciousness research, contemporary psychiatry, and neurocomputation. The neurophenomenology research program, pioneered by Varela (1996), rigorously examines subjective experience using first-person methodologies, inspired by phenomenology and contemplative practices. This review explores recent advancements in neurophenomenological approaches, particularly their application to meditation practices and potential clinical research translations.

Article Synopsis
  • This study aimed to explore the effects of an 18-month meditation program on cardiovascular health in older adults aged 65 and above.
  • The results showed no significant difference in overall cardiovascular risk (measured by the Framingham Risk Score) between those who practiced meditation and those in control groups.
  • However, meditation did lead to a notable reduction in diastolic blood pressure among participants at higher cardiovascular risk, suggesting potential benefits for specific at-risk groups.

Meditation is a family of ancient and contemporary contemplative mind-body practices that can modulate psychological processes, awareness, and mental states. Over the last 40 years, clinical science has manualised meditation practices and designed various meditation interventions (MIs), that have shown therapeutic efficacy for disorders including depression, pain, addiction, and anxiety. Over the past decade, neuroimaging has examined the neuroscientific basis of meditation practices, effects, states, and outcomes for clinical and non-clinical populations.

Understanding the factors that predict why some individuals perceive to respond more to meditation training than others could impact the development, efficacy, adherence levels, and implementation of meditation-based interventions. We investigated individual-level variables associated with self- and teacher-perceived responsiveness to longer-term meditation training. This study presents a secondary analysis of the Age-Well trial (NCT02977819, 30/11/2016) and includes 90 healthy older adults (65-84 years) that were randomised to an 18-month meditation training or a non-native language (English) training.

The K-sample testing problem involves determining whether K groups of data points are each drawn from the same distribution. Analysis of variance is arguably the most classical method to test mean differences, along with several recent methods to test distributional differences. In this paper, we demonstrate the existence of a transformation that allows K-sample testing to be carried out using any dependence measure.

Introduction: With the growing population of pancreas transplant recipients followed long-term, some female recipients are going to require surgical intervention for gynecologic symptoms and pathologies. Currently, there is a lack of literature describing how to approach this population and whether pelvic gynecologic procedures (GYN) can be performed safely given the proximity of the pancreatic (and possibly renal) allograft. In this single-center retrospective analysis, all pancreas transplant recipients that subsequently underwent GYN were reviewed.

Background: COVID-19 pandemic and confinement measures had a major impact on the health and well-being of the population. Health promotion and prevention (HP&P) professionals had to rethink their practices to respond to the challenges raised by the pandemic context. This study aimed to build a professional consensus on the HP&P priorities (apart from the COVID-19 fight) in the early times of the pandemic in Switzerland and to identify the most relevant interventions to respond to these issues.

Article Synopsis
  • The aquatic γ-proteobacterium can form two types of biofilms: a floating pellicle at the air-liquid interface and a solid surface-associated biofilm (SSA-biofilm).
  • The Bpf system, which is similar to the Lap system, is essential for the formation of the pellicle biofilm but is not necessary for SSA-biofilm formation, highlighting its unique role.
  • BpfD, a protein involved in pellicle formation, binds c-di-GMP and interacts with other proteins like PdgA and CheY3, suggesting that biofilm development is regulated by a complex c-di-GMP signaling network.

  • AI models for medical imaging need large and diverse datasets, which are hard to obtain due to privacy concerns and data sharing issues.
  • Synthetic medical imaging data, generated by AI, can help address these shortages while allowing for new applications and professional training.
  • However, using synthetic data raises challenges related to realism, evaluation of model performance, high costs, and the need for updated regulations to ensure ethical use, highlighting the importance of collaboration between regulatory bodies, physicians, and AI developers.

Background: Doxorubicin (DOX) has been widely used in the treatment of breast cancer, but it is directly associated with late-onset cardiovascular disease (CVD). Whether anthropometric, food intake or other risk factors together with DOX-based chemotherapy can increase the risk of developing cardiotoxicity remains uncertain. We examined the association between anthropometric variables with doxorubicin-induced cardiotoxicity in women with breast cancer.

Aging is associated with cognitive changes, even in the absence of brain pathology. This study aimed to determine if meditation training, by comparison to active and passive control groups, is linked to changes in the perception of cognitive functioning in older adults. One hundred thirty-four healthy older participants from the Age-Well Randomized Clinical Trial were included: 45 followed a meditation training, 45 a non-native language training and 44 had no intervention.

An appropriately designed pharmacokinetic (PK) assay that is sensitive for anti-drug antibody (ADA) impact on relevant exposure is an alternative strategy to understand the neutralizing potential of ADAs. However, guidance on how to develop such PK assays and how to confirm the functional ADA impact on exposure is missing. Here, the PK assay of a T-cell-engaging bispecific antibody, cibisatamab, was developed based on its mechanism of action (MoA).

Peripheral nerve imaging provides information that can be critical to the diagnosis, staging, and management of peripheral neuropathies. MRI and ultrasound are the imaging modalities of choice for clinical evaluation of the peripheral nerves given their high soft tissue contrast and high resolution, respectively. This AJR Expert Panel Narrative Review describes MRI- and ultrasound-based techniques for peripheral nerve imaging; highlights considerations for imaging in the settings of trauma, entrapment syndromes, diffuse inflammatory neuropathies, and tumor; and discusses image-guided nerve interventions, focusing on nerve blocks and ablation.

While consciousness is typically considered equivalent to mental contents, certain meditation practices-including open monitoring (OM)-are said to enable a unique conscious state where meditators can experience mental content from a de-reified perspective as "ongoing phenomena." Phenomenologically, such a state is considered as reduction of intentionality, the mental act upon mental content. We hypothesised that this de-reified state would be characterised by reduced mental actional processing of affording objects.
