Background Species (spp.) belonging to the genus Fusobacterium are anaerobic commensals colonizing the upper respiratory tract, the gastrointestinal tract and the genitals. Infections with Fusobacterium spp. have been reported at many anatomical sites, including pneumonias and pleural empyemas, however there are very few published cases of Fusobacterium spp. causing spondylodiscitis or fistulas. Bone infections with Fusobacterium can spread directly to surrounding muscular tissue or by hematogenous transmission to any other tissue including pleurae and lungs. Similarly, pleural infections can spread Fusobacterium spp. to any other tissue including fistulas and bone. Concomitant pleural empyema and spondylodiscitis is rare, however there are a few published cases with concomitant disease, although none caused by Fusobacterium spp. Case presentation A 77 years old female patient was assessed using computed tomography (CT) scanning of the thorax and abdomen, as well as analyses of fluid drained from the region affected by the pleural empyema. A diagnosis of Fusobacterium empyema, fistula, bacteremia and spondylodiscitis was made, and the patient's condition improved significantly after drainage of the pleural empyema and relevant long-term antibiotic treatment. Conclusions We describe the first confirmed case with concomitant infection with Fusobacterium nucleatum. as spondylodiscitis and pleural empyema connected by a fistula.

Acute respiratory distress syndrome (ARDS) is an acute inflammation of the lung resulting from damage to the alveolar–capillary membrane, and it is diagnosed using a combination of clinical and physiological variables. ARDS develops in approximately 10% of hospitalised patients with pneumonia and has a mortality rate of approximately 40%. Recent research has identified several biomarkers associated with ARDS pathophysiology, and these may be useful for diagnosing and monitoring ARDS. They may also highlight potential therapeutic targets. This review summarises our current understanding of those clinical biomarkers: (1) biomarkers of alveolar and bronchiolar injury, (2) biomarkers of endothelial damage and coagulation, and (3) biomarkers for treatment responses.

To the Editor, In a recent report in this journal, the clinical characteristics and outcomes of hospitalized adult COVID-19 and influenza patients were compared [1]. Although the COVID-19 patients ...

Patients admitted to hospital with coronavirus disease 2019 (COVID-19) may develop acute respiratory failure (ARF) with compromised gas exchange. These patients require oxygen and possibly ventilatory support, which can be delivered via different devices. Initially, oxygen therapy will often be administered through a conventional binasal oxygen catheter or air-entrainment mask. However, when higher rates of oxygen flow are needed, patients are often stepped up to high-flow nasal cannula oxygen therapy (HFNC), continuous positive airway pressure (CPAP), bilevel positive airway pressure (BiPAP), or invasive mechanical ventilation (IMV). BiPAP, CPAP, and HFNC may be beneficial alternatives to IMV for COVID-19-associated ARF. Current evidence suggests that when nasal catheter oxygen therapy is insufficient for adequate oxygenation of patients with COVID-19-associated ARF, CPAP should be provided for prolonged periods. Subsequent escalation to IMV may be implemented if necessary.

Introduction: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has presented health-care systems worldwide with novel challenges and experiences and evidence is emerging during the pandemic. Patients requiring hospitalization frequently suffer from respiratory failure of different severities. Aim: The aim of this guideline is the treatment of patients with SARS CoV-2 (COVID-19) in hospital; in particular, it addresses the treatment of respiratory failure treated in general Internal Medical- and Pulmonary Medical wards. Results: Elderly patients and patients with chronic disease are particularly vulnerable to COVID-19. Target oxygen saturation should be between 92% and 96% in patients without chronic lung diseases. Treatment with >5 L oxygen/min should be in close collaboration with intensive care colleagues and >15 l/min preferably in intensive care units. High-flow nasal canula (HFNC) and long-term Continuous Positive Airway Pressure (CPAP) are recommended for patients not responding to conventional oxygen therapy. Non-invasive ventilation (NIV) is only recommended for selected patients, such as those with a ceiling of treatment or patients presenting with hypercapnic failure. With the use of humidification protective equipment as FFP2-3 masks should be used. Nebulized medication should be avoided, and spacers should be used instead. Conclusion: Respiratory failure is frequently the cause of hospitalization in patients with COVID-19 and should be monitored closely.

It is still a matter of debate whether the outcome of community acquired pneumonia is more severe in patients with chronic obstructive pulmonary disease. We aimed to determine whether chronic obstructive pulmonary disease was associated with increased mortality and to identify risk-factors for mortality in patients with community acquired pneumonia and chronic obstructive pulmonary disease.Retrospective cohort study comparing patients with community acquired pneumonia and chronic obstructive pulmonary disease to patients without chronic obstructive pulmonary disease. We included 1309 patients with community acquired pneumonia admitted from 2011 until 2012 (243 patients with chronic obstructive pulmonary disease and 1066 without chronic obstructive pulmonary disease).At admission patients with community acquired pneumonia and chronic obstructive pulmonary disease presented with more severe pneumonia as measured by CURB-65 score compared to patients without chronic obstructive pulmonary disease. Mortality on day 30 was generally high, and higher among patients with community acquired pneumonia and chronic obstructive pulmonary disease compared to those without chronic obstructive pulmonary disease (16.0% versus 11.3%, p = .04). In an adjusted analysis, however, chronic obstructive pulmonary disease was not independently associated with 30-d mortality (odds ratio 0.94, confidence interval 95% 0.59-1.50). Factors related to mortality in patients with community acquired pneumonia and chronic obstructive pulmonary disease were age, premorbid condition, severity of pneumonia as determined by CURB-65 score, and pleural effusion and multi-lobular infiltrate on chest X-ray.Chronic obstructive pulmonary disease was not independently associated with 30-d mortality in patients with community acquired pneumonia.

We describe characteristics and risk factors regarding pregnancy outcome in women with a preconception body mass index (BMI) >50 kg/m² compared with women with BMI ≤50 kg/m² in a retrospective population cohort study in singleton pregnancies from the Danish Medical Birth Registry. Results were analyzed as relative risks by a two-proportion z-test. Women with preconception BMI >50 kg/m² smoked, developed gestational diabetes and pre-eclampsia, and needed induction of labor more frequently than mothers with BMI ≤50 kg/m². Examination of the case records showed that many attempted vaginal delivery without epidural analgesia, 21% needed an emergency cesarean section (compared with 12% among women with BMI ≤50 kg/m²), and 25% underwent general anesthesia in this context. Many neonates were macrosomic and 34% needed neonatal intensive care and early feeding compared with 6% of neonates from women with BMI ≤50 kg/m². Women with an extremely high preconception BMI develop more pregnancy complications and their neonates appear affected by this as well.

Introduction Very few studies describe the obstetric and neonatal outcome of spontaneous pregnancies in women with irregular menstrual cycles. However, menstrual cycle irregularities are common and may be associated with increased risk, and women who develop pregnancy complications more frequently recollect irregular menstrual cycles before the time of conception in case-control studies. Material and methods This retrospective cohort study compares obstetric and neonatal outcomes in spontaneous singleton pregnancies in 3440 primiparous Danish women stratified according to menstrual cycle regularity. All pregnancies delivered after 22 weeks of gestation and had a nuchal translucency examination at Copenhagen University Hospital Hvidovre between 1 January 2009 and 31 December 2010. Menstrual cycle irregularity was defined as more than 7 days' deviation between self-reported and ultrasound examination-based gestational age. Outcome measures were gestational diabetes, hypertension, preeclampsia, preterm premature rupture of membranes, preterm birth, prolonged pregnancy, birthweight, umbilical artery pH

Background The majority of patients with non-small cell lung cancer (NSCLC) are diagnosed with advanced inoperable disease. While treatment with conventional chemotherapy has improved during the last decade the 5 years survival is still modest. Novel drugs, which selectively target aberrant elements in neoplastic cells and their microenvironment have recently been and are continuously developed including drugs inhibiting the angiogenic system. Angiogenic factor vascular endothelial growth factor (VEGF) and its receptor vascular endothelial growth factor receptor 2 (VEGFR2) seem to play key roles in tumour-induced angiogenesis. Previous studies have been inconclusive on the topic of a role for VEGF and its receptor as prognostic factors in NSCLC. Methods Paraffin-embedded histological material from 102 patients operated for NSCLC was included and a representative block with lung cancer tissue was selected from each patient for immunohistochemical studies. The sections were incubated with primary monoclonal antibodies to VEGF-A and VEGFR2. The expression of the immunohistochemical staining was assessed semi-quantitatively by estimating the percentage and the intensity of tumour cells stained on whole tumour slides. Kaplan–Meier survival curves were generated to evaluate the significance of immunohistochemical VEGF-A and VEGFR2 expression for the prognosis. Results VEGF-A and VEGFR2 expression was observed in the majority of NSCLC patients. VEGF-A expression showed a correlation to histological type with increased expression in adenocarcinomas as compared to squamous cell carcinomas. There was no statistically significant correlation between VEGF-A and VEGFR2 expression and age, gender or stage at diagnosis. Finally there was no relation between expression of VEGF-A and VEGFR2, nor an effect of high expression of both VEGF-A and VEGFR2 on survival. Conclusion In conclusion VEGF-A and VEGFR2 are expressed in NSCLC, but the immunohistochemical expression of VEGF-A and VEGFR2 has no prognostic impact in NSCLC. We show that the histological subgroups of NSCLC express VEGF-A differently, with adenocarcinomas having the highest amount. Whether these markers might be useful as clinically reliable predictive markers remains to be solved.
