A 44-year-old man had persistent fever following a severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) infection. Because of progressive sinus tachycardia, thyroid hormones were measured which showed hyperthyroidism. ⋯ We diagnosed subacute granulomatous thyroiditis associated with SARS-CoV‑2 infection and initiated therapy with prednisolone. This therapy resulted in rapid improvement of the patient's clinical condition and complete remission after three months.

The etiology of hyperventilation is multifactorial. When excluding somatic causes, neurogenic hyperventilation must always be considered. Since hyperventilation itself causes neuromuscular symptoms such as paresthesia, vertigo, cephalgia, and nausea, the differential diagnosis of viral meningitis in the presence of hyperventilation is not always obvious and can easily be overlooked. Our case report shows that somatogenic causes of hyperventilation should be carefully excluded.

Alzheimer's disease (AD) is the most common cause of dementia. The number of people affected will increase dramatically in the coming decades due to the demographic change. Causal pharmacological approaches have not been available to date. The monoclonal anti-amyloid beta antibody aducanumab was recently approved for the treatment of AD in the USA but was rejected in Europe in December 2021 by the European Medicines Agency (EMA). ⋯ Anti-amyloid antibodies represent the first cause-based, disease-modifying therapy for AD approved in the USA. Compared to the near-complete removal of cerebral amyloid plaques, the magnitude of the clinical effect is smaller and the benefit for patients is currently subject to controversial discussions. Nonetheless, the new treatment option represents an important step in the development of effective treatment. Future strategies for the treatment of AD will likely aim at a multimodal concept with different molecular targets. A prerequisite for all effective disease-modifying therapies will be an early biomarker-based diagnosis prior to the onset of a dementia-type syndrome.

In August 2021, an update of the European Society of Cardiology-Heart Failure Association guideline for the diagnosis and treatment of heart failure was released. To review the changes implied by current guidelines regarding the diagnosis and treatment of patients with heart failure and preserved left ventricular ejection fraction (HFpEF). The diagnosis of HFpEF requires the combined presence of clinical signs, left ventricular ejection fraction ≥ 50%, elevated natriuretic peptides, and elevated left ventricular filling pressure. ⋯ It is expected that this finding will become part of updated treatment recommendations in the near future. Although challenging, the early diagnosis of HFpEF is key to averting the poor prognosis associated with this frequent condition. Multidisciplinary care and innovative pharmacologic and non-pharmacologic therapies, however, can improve quality of life, exercise tolerance, and prognosis.

Mobile health (mHealth) for the detection of atrial fibrillation is an innovative domestic monitoring of the heart rhythm. The use of mHealth in the context of atrial fibrillation increases the availability of diagnostic technologies and facilitates the integration into telemedical treatment concepts as well as the active participation of patients in the treatment process. The detection of atrial fibrillation with mHealth applications is usually based on electrocardiography (ECG) or by detection of the pulse wave using photoplethysmography (PPG). ⋯ Nevertheless, at present mHealth is only integrated to a limited extent into the reality of patient care. Adequate reimbursement and medical remuneration as well as opportunities to derive information and qualification are prerequisites in order to be able to guarantee a comprehensive implementation in the future. The Digital Health Care Act passed in 2019, regulates the reimbursement of digital healthcare applications but issues of primary preventive applications have not yet been included.
