Treatment decisions following severe acute brain injury need to consider patients' goals-of-care and long-term outcomes. Using family members as respondents, we aimed to assess patients' goals-of-care in the ICU and explore the impact of adaptation on survivors who did not reach the level of recovery initially considered acceptable.

Prospective, observational, mixed-methods cohort study.

Comprehensive stroke and level 1 trauma center in Pacific Northwest United States.

Family members of patients with severe acute brain injury in an ICU for greater than 2 days and Glasgow Coma Scale score less than 12.

At enrollment, we asked what level of physical and cognitive recovery the patient would find acceptable. At 6 months, we assessed level of recovery through family surveys and chart review. Families of patients whose outcome was below that considered acceptable were invited for semistructured interviews, examined with content analysis.

For 184 patients, most family members set patients' minimally acceevere acute brain injury, most patients survived to a state their families initially thought would not be acceptable. Survivors and their families need more support and guidance as they adapt to a new normal and struggle with persistent uncertainty.

Eleven months into the coronavirus disease 2019 pandemic, the country faces accelerating rates of infections, hospitalizations, and deaths. Little is known about the experiences of critical care physicians caring for the sickest coronavirus disease 2019 patients. Our goal is to understand how high stress levels and shortages faced by these physicians during Spring 2020 have evolved.

We surveyed (October 23, 2020 to November 16, 2020) U.S. critical care physicians treating coronavirus disease 2019 patients who participated in a National survey earlier in the pandemic (April 23, 2020 to May 3, 2020) regarding their stress and shortages they faced.

ICU.

Coronavirus disease 2019 patients.

Irrelevant.

Physician emotional distress/physical exhaustion low (not at all/not much), moderate, or high (a lot/extreme). Shortage indicators insufficient ICU-trained staff and shortages in medication, equipment, or personal protective equipment requiring protocol changes.

Of 2,375 U.S. critical care attending phyand, to a lesser degree, personal protective equipment shortages faced by U.S. critical care physicians remain high. Stress levels were higher among women. Considering the persistence of these findings, rising levels of infection nationally raise concerns about the capacity of the U.S. critical care system to meet ongoing and future demands.

Bronchoscopic thermal vapour ablation (BTVA) is an established and approved modality for minimally invasive lung volume reduction in severe emphysema. Preclinical data suggest potential for BTVA in minimally invasive ablation of lung cancer lesions.

The objective of this study is to establish the safety, feasibility, and ablative efficacy of BTVA for minimally invasive ablation of lung cancers.

Single arm treat-and-resect clinical feasibility study of patients with biopsy-confirmed lung cancer. A novel BTVA for lung cancer (BTVA-C) system for minimally invasive treatment of peripheral pulmonary tumours was used to deliver 330 Cal thermal vapour energy via bronchoscopy to target lesion. Patients underwent planned lobectomy to complete oncologic care. Pre-surgical CT chest and post-resection histologic analysis were performed to evaluate ablative efficacy.

Six patients underwent BTVA-C, and 5 progressed to planned lobectomy. Median procedure duration was 12 min. No major procedure-related complications receiving sufficient thermal dose per volume of lung. Treatment of smaller volumes and ensuring adequate thermal dose may be important for ablative efficacy.

Tumor necrosis factor alpha (TNFα) is a pro-inflammatory cytokine that may paradoxically induce either apoptosis or cell survival. It mediates its activity through binding of TNF-receptor (TNFR) 1 or 2. TNFR1 is mainly responsible for transmitting apoptotic signals. The activation of apoptotic mechanisms can either be intrinsic (mitochondrial) or extrinsic (death receptors). Death ligands such as TNF-related apoptosis-inducing ligand (TRAIL) specifically induce extrinsic apoptosis, while cytostatic drugs such as 5-fluorouracil (5FU) induce intrinsic apoptosis.

To investigate the effects of TNFα on apoptosis in malignant and normal human keratinocytes.

Human cutaneous squamous cell carcinoma (SCC) cell line SCC-13 and immortalized human keratinocytes HaCaT as well as primary normal human keratinocytes (PNHK) were stimulated with TNFα and then treated either with TRAIL or 5FU. Cell viability and cell proliferation, DNA fragmentation, apoptosis, and cytotoxicity were determined by WST-1 proliferation assay, ELISA, flow cytometry, and colorimetric analysis of lactate dehydrogenase, respectively. In addition, Western blotting was performed for analysis of caspase-3.

TNFα affected viability of SCC-13 and HaCaT cells in combination with 5FU or TRAIL. In contrast, TNFα did not influence cell viability of PNHK. It enhanced the apoptotic effects of both extrinsic and intrinsic stimuli in SCC-13 and HaCaT. In clear contrast, TNFα protected PNHK against TRAIL- and 5FU-induced apoptosis. The effects were dose-dependent and TNFα-specific; furthermore, the apoptosis pathway was caspase-dependent.

In summary, opposing effects of TNFα in malignant versus normal human keratinocytes were observed with possibly relevant clinical implications, when patients are treated with TNFα inhibitors.

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is an unusual form of T-cell non-Hodgkin lymphoma. Surgical management is essential; however, adjuvant therapy is recommended for advanced stages of cancer.

A 40-year-old woman with textured silicone implants placed 7 years earlier, presented with breast nodules. Physical examination and computed tomography (CT) revealed a left parasternal mass, 2 left-breast nodules, and axillary lymphadenopathies. A soft-tissue lesion in the anterior mediastinum consistent with thymic remnants was detected. BIA-ALCL was diagnosed based on ultrasound-guided core biopsies of an axillary lymph node and a breast nodule. She underwent total bilateral capsulectomy and received anthracycline-based adjuvant chemotherapy. see more End-of-treatment positron emission tomography-computed tomography (PET-CT) scan at 4 months showed no evidence of disease, except for the persistence of the mediastinal lesion (Deauville score 4). Three months later, a new PET-CT scan showed enlargement of the lesion and increased radiotracer uptake, suggesting metabolic progression.
