RESUMO
Hypertension (also known as high blood pressure), is a medical condition characterized as a persistently raised blood pressure of the pulmonary artery. Effective interventions to treat hypertension typically involve two approaches: lifestyle modifications and pharmacotherapy. One specific lifestyle intervention which aims to increase calcium uptake through dietary supplementation, has recently gained popularity because of its potential to be low-cost and population based. Research suggests that this intervention may be effective given that calcium has been found to have an inverse relationship with blood pressure and hypertension. That said, studies have shown that there may be potential risks to patient health through adverse events such as kidney stone formation and increased cardiovascular events. Association between calcium supplementation and adverse events could have an impact on population health and prevent widespread adoption of the intervention. Because of the need to establish the effectiveness of this intervention assessed against any possible harms, it is now necessary to review the current evidence and evaluate its implications for clinical practise.
RESUMO
PURPOSE: The aim of this review is to assess the efficacy and safety of using heat and cold therapy for adults with lymphoedema. METHODS: A multi-database search was undertaken. Only studies which included adults with lymphoedema who were treated with heat or cold therapy reporting any outcome were included. Screening, data extraction, and assessment of bias were undertaken by a single reviewer and verified by a second. Due to the substantial heterogeneity, a descriptive synthesis was undertaken. RESULTS: Eighteen studies were included. All nine studies which assessed the effects of heat-therapy on changes in limb circumference reported a point estimate indicating some reduction from baseline to end of study. Similarly, the five studies evaluating the use of heat-therapy on limb volume demonstrated a reduction in limb volume from baseline to end-of-study. Only four studies reported adverse events of which all were deemed to be minor. Only two studies explored the effects of cold therapy on lymphoedema. CONCLUSIONS: Tentative evidence suggests heat-therapy may have some benefit in treating lymphoedema with minimal side effects. However, further high-quality randomised controlled trials are required, with a particular focus on moderating factors and assessment of adverse events.Implications for rehabilitationThis review highlights the potential benefit that heat therapy may have on reducing limb circumference and volume for adults with lymphoedema.There was no evidence that controlled localised heat therapy was unsafe.The current evidence-base is at a point where no specific clinical recommendations can be made.The use of heat therapy should only be applied as part of a methodologically robust study to treat lymphoedema.
RESUMO
Cardiovascular disease remains one of the most prevalent and preventable chronic conditions worldwide. Nutrition plays an important role in reducing several risk factors associated with cardiovascular disease. Intermittent fasting has been rapidly gaining interest among patients with cardiometabolic disease as a nutritional strategy for improving cardiovascular outcomes. However, research had yet to determine whether intermittent fasting provides greater cardiometabolic benefits compared to continuous daily caloric restriction. A recent Cochrane review has synthesised the benefits of intermittent fasting for the prevention of cardiovascular disease but is limited by its interpretation of the findings for clinical practice. This commentary aims to critically appraise the methods used within the review by Allaf et al, 2021 and expand upon the findings to determine its implications for clinical practice.
RESUMO
It is estimated that 200 million people are living with coronary heart disease, which remains one of the leading causes of mortality and morbidity worldwide. Those living with coronary heart disease are at an increased risk of cardiovascular events such as stroke, myocardial infarction, and cardiovascular death. Pathophysiology of coronary heart disease revolves around inflammation which leads to plaque build-up. Antibiotics are known to hold anti-inflammatory and anti-oxidative properties. It is theorized that reductions in inflammation could prevent cardiovascular events which may reduce suffering, risk of death and hospital admission rates in patients with coronary heart disease. This article critically appraises a systematic review that assessed the risk of antibiotics used as secondary prevention for coronary heart disease.
RESUMO
Stroke remains one of the leading causes of death worldwide. In order to tackle the negative impacts of stroke, a high standard of clinical practice and a commitment to continuous quality improvement is needed across the stroke care pathway. One approach to quality improvement is the formation and implementation of quality improvement collaboratives (QIC's). However, there are several barriers to the implementation of a QIC for stroke care which may impact on their success. This article critically appraises a systematic review which assessed the effectiveness of QIC's for driving improvements in stroke care and explored the barriers to implementing a QIC's to improve care.
RESUMO
The prognosis of patients with the coronavirus disease 2019 (COVID-19) is determined by the severity of lower respiratory infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The majority of patients demonstrate mild symptoms only. However, development of pneumonia is associated with the risk of severe respiratory insufficiency. Reverse transcriptase polymerase chain reaction (RT-PCR) of specimens from the upper and/or lower respiratory tract is the gold standard for the diagnosis of COVID-19. Radiology and especially high-resolution computed tomography (HRCT) are important for diagnosis and follow-up. This narrative review provides an overview of clinical signs and the complex and unique pathophysiology of COVID-19 pneumonia. Radiological features are addressed. Therapy is mainly supportive with the most important task being management of respiratory insufficiency. Recently, promising data were presented regarding effectiveness of antiviral and anti-inflammatory drugs.
RESUMO
Coronavirus disease 2019 (COVID-19) continues to pose a major global threat. Although a wide range of organ manifestations have now been described, the respiratory system remains in the forefront in terms of the course of infection. Severe pneumonia can develop and is generally prognostically relevant. The following article discusses currently known features of these pulmonary manifestations from a pathophysiological, symptomatological, and radiological perspective. With regard to pathophysiology, the complex nature of the acute pulmonary disease involving severe injury to the alveolar epithelium and pulmonary vascular endothelium resulting in severe respiratory failure in a proportion of patients is discussed. The differences from "classic" acute respiratory distress syndrome and the major effects these have on the treatment of COVID-19 are elucidated. Following a brief description of PCR-based pathogen identification and information on typical laboratory findings, imaging of COVID-19 pneumonia is described in greater details (typical findings, differential diagnoses, grading of the likelihood of COVID-19 pneumonia). This is followed by a description of symptoms, which develop in three phases. With regard to treatment, supportive and intensive care approaches are discussed, including O2 administration and (non-)invasive ventilation. The article concludes with a summary of the insights gained into pharmacological therapies: thrombosis prevention on the one hand, and specific antiviral and immunomodulatory therapies (remdesivir, tocilizumab, anakinra, dexamethasone) on the other.

Clinically amyopathic dermatomyositis (CADM) is a rare entity of dermatomyositis. As a rule, CADMâpresents without muscular involvement. Thus, the level of creatine kinase is most commonly within the normal range. Dermal manifestations of CADMâare Gottron's papules and mechanic's hands. In the case of melanoma differentiation-associated gene 5 intracellular pathogen sensor (MDa5 antibodies), CADMâis often associated with a rapidly progressive and severe form of interstitial lung disease. Pulmonary function tests reveal restriction and hypoxemia of varying degree. Features of ground-glass opacities, reticulations and consolidations are detected in high-resolution CT scan. Lymphocytes are sometimes predominant in bronchioloalveolar lavage. Pathologists see a picture similar to non-specific interstitial lung disease or organizing pneumonia. Pronounced immunosuppression is the most common therapy. However, sometimes a combination of different immunosuppressive therapies is necessary. A novel strategy to treat CADMâwith rapidly progressive interstitial lung disease is the Janus kinase inhibitor tofacitinib. Treatment can be monitored with the level of ferritin and MDa5-antibody titer. Mortality is as high as 84â%.

Idiopathic pulmonary fibrosis (IPF) is a specific form of chronic progressive fibrosing interstitial lung disease with a poor prognosis. High-resolution computed tomography (HRCT) plays an important role in the work-up of patients with suspected IPF. In HRCT IPF is characterized by the pattern of usual interstitial pneumonia (UIP). For a long time only supportive or immunosuppressive treatment was possible. The approval of antifibrotic agents in 2012 marked a turning point and triggered further clinical and scientific interest. Based on the recently gained knowledge the revised version of the international guidelines for the diagnosis of IPF was published in 2018, including instructions for HRCT interpretation. In this continued medical education article the relevant signs in HRCT are presented. The specifications given in the guidelines are elucidated.

Pulmonary alveolar proteinosis (PAP) is a rare pulmonary disease. PAP results from impaired surfactant clearance. In adults, autoimmune pulmonary alveolar proteinosis is present in 90â-â95â% of the cases. In 5â-â10â%, other etiologies such as toxins and dust exposure, hematological disorders and infections have to be considered. Men between 30â-â60 years are commonly affected. Typical symptoms are cough, dyspnea and alteration in ventilatory function. CT scan of the lung is characterised by a crazy paving pattern. In serological testing, granulocyte macrophage colony-stimulation factor can be identified in most patients with autoimmune pulmonary alveolar proteinosis. Whole-lung lavage remains the therapy of choice. In the current case, treatment with whole-lung lavage resulted in clinical and functional improvement.

UNLABELLED: The Fleischner Society has published several recommendations for terms for thoracic imaging. The most recent glossary was released in 2008. One glossary in German language was published in 1996. This review provides an updated German glossary of terms for thoracic imaging. It closely adheres to the Fleischner Society terminology. In some instances adaptions to the usage of German language were necessary, as well as some additions of terms which were later defined or redefined. These deviations are summarized in a revision report. KEY POINTS: The Fleischner Society has published a revised version of her glossary of terms for thoracic imaging in 2008. This paper presents a German adaption of this glossary. Some terms not contained in the original version have been added. The general use of the presented terminology in radiological reports is recommended.

Drug-induced interstitial lung diseases (DILD) are probably more common than diagnosed. Due to their potential reversibility, increased vigilance towards DILD is appropriate also from the radiologist's point of view, particularly as these diseases regularly exhibit radiological correlates in high-resolution computed tomography (HRCT) of the lungs.Based on personal experience typical relatively common manifestations of DILD are diffuse alveolar damage (DAD), eosinophilic pneumonia (EP), hypersensitivity pneumonitis (HP), organizing pneumonia (OP), non-specific interstitial pneumonia (NSIP) and usual interstitial pneumonia (UIP). These patterns are presented based on case studies, whereby emphasis is placed on the clinical context. This is to highlight the relevance of interdisciplinary communication and discussion in the diagnostic field of DILD as it is a diagnosis of exclusion or of probability in most cases.Helpful differential diagnostic indications for the presence of DILD, such as an accompanying eosinophilia or increased attenuation of pulmonary consolidations in amiodarone-induced pneumopathy are mentioned and the freely available online database http://www.pneumotox.com is presented.

The increasing availability of computed tomography has meant that the number of incidentally detected solitary pulmonary nodules (SPN) has greatly increased in recent years. A reasonable management of these SPN is necessary in order to firstly be able to detect malignant lesions early on and secondly to avoid upsetting the patient unnecessarily or carrying out further stressful diagnostic procedures. This review article shows how the dignity of SPNs can be estimated and based on this how the management can be accomplished taking established guidelines into consideration.

Magnetic resonance imaging (MRI) is a mainstay in musculoskeletal imaging. The term"bone marrow edema" is frequently used for describing the radiological findings, especially with respect to rheumatic diseases. The referring physician should be aware that this term has a purely descriptive character and the pathophysiology of signal alterations in MRI shows a broad spectrum certainly not always corresponding to increased liquid contents. The recommendations therefore tend towards the use of the neutral terms"osteitis","bone marrow edema-like lesion" or"bone marrow lesion" instead of the misleading term"bone marrow edema".

PURPOSE: This study was designed to determine the feasibility and efficacy of endovascular embolization with liquid embolic agent ethylene vinyl alcohol copolymer (Onyx) in patients with acute traumatic arterial bleeding. METHODS: This is a retrospective review of 13 patients (9 men and 4 women; mean age 45 years) with severe trauma who underwent embolotherapy using Onyx from November 2003 to February 2009. Bleeding was located in the pelvis (5 patients), kidney (3 patients), mesenteric region (2 patients), retroperitoneal space (2 patients), neck (1 patient), and thigh (1 patient). In three cases (23.1%), Onyx was used in conjunction with coils. We evaluate the technical and clinical success, procedural and embolization time, occurrence of rebleeding, and embolotherapy-related complications, such as necrosis or migration of Onyx into nontarget vessels. RESULTS: In all patients, embolotherapy was technically and clinically successful on the first attempt. Control of bleeding could be reached with a mean time of 19 (range, 4-63) min after correct placement of the microcatheter in the feeding artery. No recurrent bleeding was detected. No unintended necrosis or migration of Onyx into a nontarget region was observed. During the follow-up period, three patients (23.1%) died due to severe intracranial hemorrhage, cardiac arrest, and sepsis. CONCLUSIONS: Transcatheter embolization with new liquid embolic agent Onyx is technically feasible and effective in trauma patients with acute arterial hemorrhage.
