- Reporting a measurement procedure and its analytical performance following method evaluation in a peer-reviewed journal is an important means for clinical laboratory practitioners to share their findings. It also represents an important source of evidence base to help others make informed decisions about their practice. At present, there are significant variations in the information reported in laboratory medicine journal publications describing the analytical performance of measurement procedures. These variations also challenge authors, readers, reviewers, and editors in deciding the quality of a submitted manuscript. The International Federation of Clinical Chemistry and Laboratory Medicine Working Group on Method Evaluation Protocols (IFCC WG-MEP) developed a checklist and recommends its adoption to enable a consistent approach to reporting method evaluation and analytical performance characteristics of measurement procedures in laboratory medicine journals. It is envisioned that the Laboratory Evaluation and Analytical Performance Characteristics (LEAP) checklist will improve the standardisation of journal publications describing method evaluation and analytical performance characteristics, improving the quality of the evidence base that is relied upon by practitioners.

- Material and methods: We used three groups of mice, stressed control (SC, stressed but not immunized with a mite antigen), non-stressed eczematous (NSE, not stressed but immunized) and stressed eczematous (SE, stressed and immunized). Results: There was a decrease of protein gene product (PGP) 9.5 positive nerve fibers in SE compared to SC mice, in both epidermis and dermis, also in SE compared to NSE mice. Also a decrease in growth associated protein (GAP)-43 positive nerve fibers was seen in SE compared to SC, in both epidermis and dermis. Conclusion: Chronic mild stress in atopic mice leads to decreased innervation in eczematous lesions.

Enterochromaffin 5-HT cells : A major target for GLP-1 and gut microbial metabolites
- 2018

- Objectives5-HT storing enterochromaffin (EC) cells are believed to respond to nutrient and gut microbial components, and 5-HT receptor-expressing afferent vagal neurons have been described to be the major sensors of nutrients in the GI-tract. However, the molecular mechanism through which EC cells sense nutrients and gut microbiota is still unclear.Methods and resultsTPH1, the 5-HT generating enzyme, and chromogranin A, an acidic protein responsible for secretory granule storage of 5-HT, were highly enriched in FACS-purified EC cells from both small intestine and colon using a 5-HT antibody-based method. Surprisingly, EC cells from the small intestine did not express GPCRsensors for lipid and protein metabolites, such as FFAR1, GPR119, GPBAR1(TGR5), CaSR, and GPR142, in contrast to the neighboring GLP-1 storing enteroendocrine cell. However, the GLP-1 receptor was particularly highly expressed and enriched in EC cells as judged both by qPCR and by immunohistochemistryusing a receptor antibody. GLP-1 receptor agonists robustly stimulated 5-HT secretion from intestinal preparations using both HPLC and a specific amperometricmethod. Colonic EC cells expressed many different types of known and potential GPCR sensors of microbial metabolites including three receptors for SCFAs, i.e. FFAR2, OLF78, and OLF558 and receptors for aromatic acids, GPR35; secondary bile acids GPBAR1; and acyl-amides and lactate, GPR132.ConclusionNutrient metabolites apparently do not stimulate EC cells of the small intestine directly but through a paracrine mechanism involving GLP-1 secreted from neighboring enteroendocrine cells. In contrast, colonic EC cells are able to sense a multitude of different metabolites generated by the gut microbiota as well as gut hormones, including GLP-1.

- Cholecystokinin (CCK) is widely distributed in the brain and is known to affect behavioral and physiological functions including anxiety and pain. The expression of CCK has been shown to be regulated by estrogen and to vary during the estrous cycle in rat brain. In the present study CCK was determined in plasma from 25 healthy women (age 25.0 +/- 3.5) during the menstrual cycle, in the late luteal phase and in the follicular phase. In the follicular phase, a lumbar puncture was performed at the same time that a plasma sample was taken in 15 subjects. The participants had fasted and were nicotine-free for at least 8 h preceding the sampling. We compared CCK-like immunoreactivity (CCK-LI) in plasma from 25 subjects in the late luteal phase (LLP) and the follicular phase (FP) and found that there was no difference during the menstrual cycle (n-25, R-2 =89.60%, p = n.s.). In the follicular phase no significant difference was found between CCK-LI in plasma and in cerebrospinal fluid (CSF) collected at the same time (n =15, R-2 = 55.32%, p = n.s.).

- Objective: The effect of combined oral contraceptives (COCs) on female sexuality has long been a matter of discussion, but placebo-controlled studies are lacking. Thus, the aim of the present study was to investigate if an oestradiol-containing COC influences sexual function.Design: Investigator-initiated, randomised, double-blinded, placebo-controlled clinical trial where 202 healthy women were randomised to a combined oral contraceptive (1.5 mg oestradiol and 2.5 mg nomegestrol acetate) or placebo for three treatment cycles.Methods: Sexual function at baseline and during the last week of the final treatment cycle was evaluated by the McCoy Female Sexuality Questionnaire. Serum and hair testosterone levels were assessed at the same time points.Results: Compared to placebo, COC use was associated with a small decrease in sexual interest (COC median change score: -2.0; interquartile range (IQR): -5.0 to 0.5 vs placebo: -1.0; IQR: -3.0 to 2.0, P=0.019), which remained following adjustment for change in self-rated depressive symptoms (B= -0.80 +/- 0.30, Wald =7.08, P=0.008). However, the proportion of women who reported a clinically relevant deterioration in sexual interest did not differ between COC or placebo users (COC 18 (22.2%) vs placebo 16 (17.8%), P=0.47). Change in other measured aspects of sexual function as well as total score of sexual function did not differ between the two treatments.Conclusions: This study suggests that use of oestradiol-based COCs is associated with reduced sexual interest. However, the changes are minute, and probably not of clinical relevance.

- The aim of this study was to analyse the dynamics of tissue damage and inflammatory response markers perioperatively and whether these differ between women operated with robotic and abdominal hysterectomy in treating early-stage endometrial cancer. At a Swedish university hospital fifty women with early-stage low-risk endometrial cancer were allocated to robotic or abdominal hysterectomy in a randomiszed controlled trial. Blood samples reflecting inflammatory responses (high sensitivity CRP, white blood cells (WBC), thrombocytes, IL-6, cortisol) and tissue damage (creatine kinase (CK), high-mobility group box 1 protein (HMGB1)) were collected one week preoperatively, just before surgery, postoperatively at two, 24 and 48hours, and one and six weeks postoperatively. High sensitivity CRP (p=0.03), WBC (p<0.01), IL-6 (p=0.03) and CK (p=0.03) were significantly lower in the robotic group, but fast transitory. Cortisol returned to baseline two hours after robotic hysterectomy but remained elevated in the abdominal group comparable to the preoperative high levels for both groups just before surgery (p<0.0001). Thrombocytes and HMGB1 were not affected by the mode of surgery. Postoperative inflammatory response and tissue damage were lower after robotic hysterectomy compared to abdominal hysterectomy. A significant remaining cortisol elevation two hours after surgery may reflect a higher stress response in the abdominal group.
