Malaria is a common infection world-wide, which carries significant risk of morbidity and mortality. Health care providers in the United States may lack experience in recognizing and treating this disease. The pathophysiology of malaria differs during pregnancy, resulting in increased risk for serious morbidity and mortality for the woman and her fetus. Screening for risk factors, especially immigration from and travel to endemic countries, is critical. Symptoms of malaria can mimic influenza-type illnesses, causing delay in diagnosis. Consultation with an infectious disease specialist and hospitalization may be required for appropriate testing and treatment. Chemoprophylaxis and counseling regarding methods to reduce risk are important components of prevention. The US Centers for Disease Control and Prevention and the World Health Organization have established protocols for treatment and are helpful resources for clinicians. A team approach to care based on the woman's stage of illness and recovery, can involve midwives, physicians, specialists and others.
  To define and evaluate hemodynamic criteria to distinguish between classical orthostatic hypotension (cOH) and vasovagal syncope (VVS) in tilt table testing (TTT).
 
  Inclusion criteria for VVS were a history of VVS and tilt-induced syncope defined as a blood pressure (BP) decrease and electroencephalographic changes during syncope with complaint recognition. Criteria for cOH were a history of cOH and a BP decrease meeting published criteria. Clinical diagnoses were established prior to TTT. We assessed (1)whether the decrease of systolic BP accelerated, "convex," or decelerated, "concave"; (2) the time from head-up tilt to when BP reached one-half its maximal decrease; (3) the difference between baseline heart rate (HR) and HR at BP nadir. We calculated the diagnostic yield of optimized thresholds of these features and their combinations.
 
  We included 82 VVS cases (40% men, median age 44years) and 65 cOH cases (66% men, median age 70years). BP decrease was concave in cOH in 79% and convex in VVS in 94% (p<0.001). The time to reach half the BP decrease was shorter in cOH (median 34sec, interquartile range (IQR) 19-98sec) than in VVS (median 1571sec, IQR 1381-1775sec, p<0.001). Mean HR increased by 11±11bpm in cOH and decreased by 20±19bpm in VVS (p<0.001).  https://www.selleckchem.com/products/bicuculline.html  When all three features pointed to VVS, sensitivity for VVS was 82% and specificity was 100%. When all three pointed to cOH, sensitivity for cOH was 71% and specificity was 100%.
 
  These new hemodynamic criteria reliably differentiate cOH from VVS.

  Posaconazole and itraconazole are commonly used for systemic antifungal prophylaxis after lung transplantation. The aim of this study on critically ill lung transplant recipients was to assess the rate of adequate plasma concentrations and the frequency of fungal-induced transitions from antifungal prophylaxis to therapy after the administration of either posaconazole or itraconazole for systemic prophylaxis.
 
  Critically ill lung transplant recipients with postoperative posaconazole or itraconazole prophylaxis and therapeutic drug monitoring from February 2016 to November 2019 were retrospectively included in the study. Positive fungal cultures or Aspergillus antigen tests resulting in a transition from antifungal prophylaxis to therapy were analyzed from the first day of prophylaxis until 7days after the last sample for each patient. Adequate plasma concentrations were defined as ≥500µg/L for itraconazole and ≥700µg/L for posaconazole.
 
  Two hundred seventy-five samples from 73 patients were included in the analysis. Overall, 60% of the posaconazole and 55% of the itraconazole concentrations were subtherapeutic. Administration of posaconazole suspension resulted significantly (P<.01) more often in subtherapeutic concentrations than tablets (68% vs 10%). Patients treated with posaconazole showed less positive fungal records resulting in a transition from prophylaxis to therapy than patients treated with itraconazole (10% vs 33%, P-value .029). The detection of a fungal pathogen was not associated with the measured plasma concentrations or the achievement of the target concentrations.
 
  Our findings suggest that posaconazole should be used instead of itraconazole for systemic prophylaxis in critically ill lung transplant recipients.

  The aim of this study was to describe the dynamic changes in blood work following individual adjusted dosage of intravenously administered iron(III) isomaltoside in a 4-week period prior to surgery in patients with colorectal cancer.
 
  This was a single-centre, observational cohort study with prospectively collected data, including patients with colorectal cancer receiving preoperative treatment with iron(III) isomaltoside. Blood samples were taken at baseline, 1 week, 2 weeks and 4 weeks after initial treatment. Sixty-two patients were included in the study.
 
  Sixty-two patients were included for final analysis. The mean increase in haemoglobin was 0.77g/dl (95% CI 0.52-1.03 g/dl, P<0.0001) at week 1, 1.5g/dl (95% CI 1.21-1.80 g/dl, P<0.0001) at week 2 and 2.13g/dl (95% CI 1.71-2.55 g/dl, P<0.0001) at week 4. Patients with severe anaemia (<9.02g/dl) showed the largest increase in haemoglobin during the treatment course (2.92g/dl, 95% CI 2.27-3.58g/dl, P<0.0001). Patients with mild anaemia (>10.31g/dl) did not show a significant increase (0.66g/dl, 95% CI -0.29-1.61 g/dl, P=0.17). The mean of transferrin saturation after 4 weeks was 8% (95% CI 6%-10%, P<0.0001).
 
  After intravenously administered iron, patients with severe anaemia had the most substantial increase in haemoglobin, and the increase was largest after 4 weeks. Patients with mild anaemia did not have an increase in haemoglobin during the treatment course. The vast majority of patients still had iron deficiency at surgery 4 weeks after the initial treatment.
