“…While all blood samples were obtained from catheters, we do not anticipate that this sampling method affected the measured Aβ concentrations compared to venous puncture sampling. 32 Additionally, we do not believe that central venous catheterization significantly altered the Aβ measurements by disrupting the BBB as the blood was collected upstream from the tip of the catheter.…”

Objective The aim of this study was to measure the flux of amyloid-β (Aβ) across the human cerebral capillary bed in order to determine if transport into the blood is a significant mechanism of clearance for Aβ produced in the central nervous system (CNS). Methods Time-matched blood samples were simultaneously collected from a cerebral vein (including the sigmoid sinus, inferior petrosal sinus, and the internal jugular vein), femoral vein, and radial artery of patients undergoing Inferior Petrosal Sinus Sampling (IPSS). For each plasma sample, Aβ concentration was assessed by three assays and the venous to arterial Aβ concentration ratios were determined. Results Aβ concentration was increased by ~7.5% in venous blood leaving the CNS capillary bed compared to arterial blood, indicating efflux from the CNS into the peripheral blood (p < 0.0001). There was no difference in peripheral venous Aβ concentration compared to arterial blood concentration. Interpretation Our results are consistent with clearance of CNS-derived Aβ into the venous blood supply with no increase from a peripheral capillary bed. Modeling these results suggests that direct transport of Aβ across the blood-brain barrier accounts for ~25% of Aβ clearance, and reabsorption of cerebrospinal fluid Aβ accounts for ~25% of the total CNS Aβ clearance in humans.

“…This approach was favored to maintain mother’s flexibility in contact with their babies during the experimental setup. Although venipuncture induces a pain stimulus and therefore may result in acute effects on circulating stress hormones, recent studies indicate that blood sampling for most laboratory tests using either direct venous puncture or peripheral venous catheter reveal comparable results (Ortells-Abuye et al, 2014). For cortisol, resting time prior to the first blood sampling may take a minimum of 30 min, which should be ameliorated in further studies.…”

Oxytocin, a small neuropeptide of nine amino acids, has been characterized as the “hormone of affiliation” and is stimulated, for instance, in mothers when interacting with their offspring. Variations in maternal oxytocin levels were reported to predict differences in the quality of care provided by mothers. In this study, the Adult Attachment Projective Picture System (AAP) as a valid measure to assess attachment representations was used as an activating attachment-related stimulus. We investigated whether the AAP induces a release of oxytocin in mothers with a secure attachment representation and a stress-related cortisol response in mothers with an insecure attachment representation. Therefore, pre-post effects of AAP administration on plasma oxytocin and serum cortisol levels were investigated in n = 44 mothers 3 months after parturition. Oxytocin levels increased from pre to post in the significant majority of 73% participants (p = 0.004) and cortisol decreased in the significant majority of 73% participants (p = 0.004). Interestingly, no association between alterations in oxytocin and cortisol were found; this suggests taking a model of two independent processes into considerations. These results show that the AAP test procedure induces an oxytocin response. Concerning the results within the four AAP representation subgroups, our hypothesis of a particularly strong increase in oxytocin in secure mothers was not confirmed; however, in secure mothers we observed a particularly strong decrease in cortisol. Effect sizes are reported, allowing the replication of results in a larger study with sufficient sample size to draw final conclusions with respect to differences in OT and cortisol alterations depending on attachment representation. When interpreting the results, one should keep in mind that this study investigated lactating mothers. Thus, the generalizability of results is limited and future studies should investigate non-lactating healthy females as well as males and include a control stimulus condition.

“…Sample sizes varied significantly with the number of patients being between 17 and 54,531 and data collection periods varying between 19 days and 12 months. A few studies excluded patients who were unstable or with multiple comorbidities (Hambleton et al, ; Himberger & Himberger, ; Ortells‐Abuye et al, ; Seemann & Reinhardt, ) and one study only included healthy volunteers (Zlotowski et al, ).…”

“…One study (Hambleton et al, ) summarized the results as all parameters were within the laboratory's accepted error except for venous blood gases. Similarly, another study (Ortells‐Abuye et al, ) also summarized blood results, which could be considered equivalent with the exception of venous blood gases. In contrast, one study (Zlotowski et al, ) found blood samples for potassium, bicarbonate and glucose were not clinically equivalent.…”

Aims To synthesize the evidence evaluating if blood samples are similar when obtained from peripheral intravenous cannula compared with venepuncture. Design A systematic review and meta‐analysis was undertaken. Data sources Searches were conducted in databases for English language studies between January 2000–December 2018. Review methods The search adhered to the Meta‐analysis of Observational Studies in Epidemiology guidelines. The methodological quality of studies was assessed using Joanna Briggs critical appraisal instruments. The overall quality of the evidence was assessed using the GRADE. Results Sixteen studies were identified. Findings suggest haemolysis rates are higher in blood sampled from peripheral intravenous cannula. However, haemolysis rates may be lower if a peripheral intravenous cannula blood sampling protocol is followed. For equivalence of blood test results, even though some results were outside the laboratory, allowable error and were outside the Bland–Altman Level of Agreement, none of these values would have required clinical intervention. With regard to the contamination rates of blood cultures, the results were equivocal. Conclusion Further research is required to inform the evidence for best practice recommendations, including, if a protocol for drawing blood from a peripheral cannula is of benefit for specific patient populations and in other settings. Impact Venepuncture can provoke pain, anxiety and cause trauma to patients. Guidelines recommend blood samples from peripheral intravenous cannula be taken only on insertion. Anecdotal evidence suggests drawing blood from existing cannulas may be a common practice. Further research is required to resolve this issue.
