Background: Preoperative localization of hyperfunctioning parathyroid glands in primary hyperparathyroidism is essential for successful parathyroid surgery, particularly in patients with previous negative imaging or reoperations.

Methods: A multicenter registry study was performed in 776 patients with primary hyperparathyroidism from 53 hospitals in Germany and Austria who underwent parathyroid surgery after preoperative F-choline or C-methionine positron emission tomography/computed tomography (PET/CT).

Results: In 683 of 776 patients (88%) (78% female, aged 15-86 years), primary hyperparathyroidism was caused by a single-gland parathyroid adenoma.

Article Synopsis
  • - The perioperative period can cause significant anxiety and depression for patients due to fears about surgery and potential complications, highlighting the need for tailored psychological support during this time.
  • - A systematic review of 25 studies found that compassion-based interventions, focusing on improved communication and emotional support from healthcare professionals, reduced anxiety in 72% of cases and also showed positive impacts on patient satisfaction and postoperative outcomes.
  • - While the results are promising, the review noted limitations, such as unclear methods in many studies and a smaller number of studies suitable for deeper analysis, suggesting that more focused research is needed to solidify these findings in routine patient care.

Objectives: Perioperative mental health of older Black surgical patients is associated with poor surgical outcomes; however, evidence-based perioperative interventions are lacking. Our two study objectives included: first, examine factors affecting perioperative care experiences of older Black surgical patients with mental health problems, and second, ascertain design and implementation requirements for a culturally-adapted perioperative mental health intervention.

Design Setting And Participants: We conducted six focus groups with older Black patients (n = 15; ≥50 years; surgery within the past 5 years and/or interest in mental health research; history of distress, anxiety, or depression coping with surgery/hospitalization/) from a large academic medical center.

Gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN) are mainly found in the small intestine and pancreas. The course of the disease in patients is highly variable and depends on the degree of differentiation (G1-G3) of the neoplasm. The potential for metastasis formation of GEP-NEN is high even with good differentiation (G1).

Preoperative depression is an underappreciated comorbidity that has important implications for postoperative outcomes. Screening for symptoms of depression before surgery can identify patients with or without a previous diagnosis of depression who could benefit from perioperative interventions to improve mood. Preoperative screening programmes are feasible to implement, although care must be taken to ensure that patients who are most likely to benefit are included.

Introduction: Preoperative anxiety and depression symptoms among older surgical patients are associated with poor postoperative outcomes, yet evidence-based interventions for anxiety and depression have not been applied within this setting. We present a protocol for randomised controlled trials (RCTs) in three surgical cohorts: cardiac, oncological and orthopaedic, investigating whether a perioperative mental health intervention, with psychological and pharmacological components, reduces perioperative symptoms of depression and anxiety in older surgical patients.

Methods And Analysis: Adults ≥60 years undergoing cardiac, orthopaedic or oncological surgery will be enrolled in one of three-linked type 1 hybrid effectiveness/implementation RCTs that will be conducted in tandem with similar methods.

Article Synopsis
  • Anxiety and depression are prevalent in older adults, particularly around surgery, but existing mental health interventions often overlook their specific needs; thus, a new perioperative mental health (PMH) bundle was developed, focusing on behavioral activation and medication optimization.
  • The research involved a combination of workshops, interviews, and audio recordings from various stakeholders to refine the PMH bundle, using multiple analytical methods to assess adaptations made based on patient and caregiver feedback.
  • Key findings revealed that nearly half of the adaptations focused on intervention content tailored to patient preferences, with the importance of compassion highlighted as a vital element, demonstrating the need for personalized approaches in mental health interventions for older surgical patients.

Anaplastic thyroid carcinoma (ATC) has poor prognosis, high mortality rate and lack of effective therapy. A synergic combination of PD-L1 antibody together with cell death promoting substances like deacetylase inhibitors (DACi) and multi-kinase inhibitors (MKI) could sensitize ATC cells and promote decay by autophagic cell death. The PD-L1-inhibitor atezolizumab synergized with panobinostat (DACi) and sorafenib (MKI) leading to significant reduction of the viability, measured by real time luminescence, of three different patient-derived primary ATC cells, of C643 cells and follicular epithelial thyroid cells too.

Background: Anxiety and depression are common among older adults and can intensify during perioperative periods, but few mental health interventions are designed for older surgical patients' unique needs. We developed and adapted a perioperative mental health (PMH) bundle for older patients comprised of behavioral activation (BA) and medication optimization (MO) to ameliorate anxiety and depressive symptoms before, during, and after cardiac, orthopedic, and oncologic surgery.

Methods: We used mixed-methods including workshop studios with patients, caregivers, clinicians, researchers, and interventionists; intervention refinement and reflection meetings; patient case review meetings; intervention session audio-recordings and documentation forms; and patient and caregiver semi-structured interviews.

Introduction: Few available data indicate that a mutation-based "neoadjuvant" therapy in advanced anaplastic thyroid carcinoma (ATC) might convert an initially unresectable primary tumor to resectable and optimize local tumor control. We evaluated a preoperative short-term "neoadjuvant" therapy with a BRAF-directed therapy or, in case of BRAF non-mutated tumors, an mKI/checkpoint inhibitor combination in three patients with ATC stage IVB and C.

Methods: In the context of preoperative diagnostics, immunohistochemistry (IHC) assessment and genetic analysis was started as soon as possible.

Brucellosis is one of the most common neglected zoonotic diseases globally, with a public health significance and a high economic loss in the livestock industry caused by the bacteria of the genus Brucella. In this study, 136 Egyptian Brucella melitensis strains isolated from animals and humans between 2001 and 2020 were analysed by examining the whole-core-genome single-nucleotide polymorphism (cgSNP) in comparison to the in silico multilocus variable number of tandem repeat analysis (MLVA-16). Almost all Egyptian isolates were belonging to the West Mediterranean clade, except two isolates from buffalo and camel were belonging to the American and East Mediterranean clades, respectively.
