Shared decision-making in advance care planning among hospitalized older COVID-19 patients: a multicenter, retrospective cohort study.

BACKGROUND: In the Netherlands, it is customary to discuss directives regarding resuscitation, intubation, and ICU-admission with patients and/or their relatives upon hospital-admission. The outcome of this discussion is documented in a code status. Ideally, these advance care planning (ACP)-related decisions are made by a patient (and/or their relatives) and a professional together in a shared decision-making (SDM) process, to improve patient satisfaction and prevent undesired care. Given the bad outcomes in older COVID-19 patients, it is particularly important to discuss the code status upon admission. This study aims to describe the practice of SDM regarding code status during the COVID-pandemic. Specific aims were to find out to what extend patients took part in this decision-making process and whether all key elements of SDM for a shared decision were documented in medical reports. METHODS: In this retrospective cohort study, we included COVID-19 patients aged 70 years and older, admitted to two large teaching hospitals in the Netherlands, during the first months of the COVID-19 pandemic in 2020. Data about code status and the decision-making process were extracted from electronic healthcare records. RESULTS: Code status was documented for 274 of 275 included patients. Patient participation in the decision-making process was described in 48%. In 19% all key elements of shared decision-making have been described. Key elements of SDM were defined as the presence of a completed code status form, the presence of clinical notes showing that both patient's wishes and values and the opinion of the healthcare professional about the predicted outcome was taken into consideration and clinical notes of a patient-healthcare professional interaction during the admission. CONCLUSION: Our results show that a proper SDM process regarding code status is possible, even in hectic times like the COVID-19-pandemic. However, shared decision-making was not common practice in older patients with COVID-19 regarding code status (an ACP-related decision) in the early phase of the COVID-19 pandemic. Only in 19% of the patients, all key elements of SDM regarding code status were described.

Professionals' views on shared decision-making in severe aortic stenosis.

OBJECTIVE: To provide insight into professionals' perceptions of and experiences with shared decision-making (SDM) in the treatment of symptomatic patients with severe aortic stenosis (AS). METHODS: A semistructured interview study was performed in the heart centres of academic and large teaching hospitals in the Netherlands between June and December 2020. Cardiothoracic surgeons, interventional cardiologists, nurse practitioners and physician assistants (n=21) involved in the decision-making process for treatment of severe AS were interviewed. An inductive thematic analysis was used to identify, analyse and report patterns in the data. RESULTS: Four primary themes were generated: (1) the concept of SDM, (2) knowledge, (3) communication and interaction, and (4) implementation of SDM. Not all respondents considered patient participation as an element of SDM. They experienced a discrepancy between patients' wishes and treatment options. Respondents explained that not knowing patient preferences for health improvement hinders SDM and complicating patient characteristics for patient participation were perceived. A shared responsibility for improving SDM was suggested for patients and all professionals involved in the decision-making process for severe AS. CONCLUSIONS: Professionals struggle to make highly complex treatment decisions part of SDM and to embed patients' expectations of treatment and patients' preferences. Additionally, organisational constraints complicate the SDM process. To ensure sustainable high-quality care, professionals should increase their awareness of patient participation in SDM, and collaboration in the pathway for decision-making in severe AS is required to support the documentation and availability of information according to the principles of SDM.

[Left ventricular noncompaction: a cardiomyopathy in young individuals. Description of first cases in Africa]. / La non compaction du ventricule gauche, une cardiomyopathie du sujet jeune: premieres observations Africaines.

Left ventricular noncompaction (LVNC) is a recently identified and probably rare congenital cardiomyopathy characterized by changes in the structure of the myocardium secondary to incomplete embryogenesis. The purpose of this report is to describe three cases of LVNC involving African patients. To our knowledge these are the first cases described in Africa. All three patients in this series were men from sub-Saharan Africa ranging in age from 23 to 45 years. The first patient in whom cardiomegaly was recognized on a routine chest x-ray was asymptomatic. The second who presented with exertional dyspnea developed left bundle branch block. The third was admitted to the hospital for acute pulmonary edema. In all three cases transthoracic echocardiography suggested diagnosis. The left ventricle was dilated and hypokinetic and the myocardium exhibited a spongy aspect in association with the presence of prominent trabeculations separated by crypts located at the apex and lateral wall. Color Doppler demonstrated that intratrabecular recesses were filled by intraventricular blood flow. Magnetic resonance imaging (MRI) specifically confirmed this morphological feature. Sudden death due to arrhythmia, cardiac insufficiency, and systemic emboli are the main complications of LVNC. The incidence of LVNC, which is certainly underestimated, is highest in young adults but it can be diagnosed at any age. Echocardiography and MRI are effective tools for detection of the morphologic diagnostic criteria. Recent evidence suggests that LVNC is of genetic origin and the data reported here shows that the underlying mutations are present in sub-Saharan populations. Family screening in African populations is still difficult. Therapeutic management is currently based on symptomatic treatment of cardiac insufficiency and can require techniques not readily available in tropical settings.

Dietary antioxidant lack, impaired hepatic glutathione reserve, and cholesterol gallstones.

BACKGROUND: Theoretical considerations and experimental studies suggest a causal connection between micronutrient antioxidant insufficiency and the development of human gallstones. METHODS: Fasting plasma/serum samples from 24 patients with cholesterol gallstones-on unchanged lifestyles-were analysed for the four main micronutrient antioxidants, glutathione and factors that impact or report upon glutathione homeostasis. The results were assessed by comparison with laboratory referent ranges. RESULTS: The vitamin E:cholesterol ratio was lower in patients than controls (P=0.021) as also concentrations of beta-carotene (P=0.001) and vitamin C (P=0.001) but not selenium (P=0.280). A fall in plasma glutathione (P=0.001) was also accompanied by lower values of pyridoxyl-5-phosphate (the coenzyme that participates in vitamin B6-dependent enzyme reactions) which is involved in glutathione biosynthesis (P<0.001), and of folate (P=0.012) but not vitamin B12 (P=0.377) that participate in its regeneration via the methionine-homocysteine pathway. Despite these defects, values for plasma homocysteine were not significantly different from controls (P=0.092)-an anomaly rationalised by poor levels of precursor methionine (P=0.003) and cysteine (P=0.046). CONCLUSIONS: Micronutrient antioxidant-including sulphur amino acid-lack, with disturbed glutathione homeostasis, are features of cholesterol gallstone disease.
