Urocortins (UCNs), belonging to corticotropin-releasing hormone (CRH) family, exert their function via CRH receptor type 1 (CRHR1) and 2 (CRHR2). Our previous studies have demonstrated that CRH acts on CRHR1 to potentiate prostaglandins (PGs) output induced by inflammatory stimuli in myometrial cells. In the present study, we sought to investigate the effects of UCNs on prostaglandin (PG) output via CRHR2 in cultured human uterine smooth muscle cells (HUSMCs) from pregnant women at term. We found that UCN and UCN 3 treatment promoted PGE2 and PGF2α secretion in a dose-dependent manner. In contrast, UCN2 dose-dependently inhibited PGE2 and PGF2α secretion. KOS 953 Their effects were reversed by CRHR2 antagonist and CRHR2 siRNA. Mechanically, we showed that UCN and UCN3 suppressed cAMP production and led to Gi activation while UCN2 stimulated cAMP production and activated Gs signaling. Further, UCN and UCN3 but not UCN2 activated NF-κB and MAPK signaling pathways through Gi signaling. UCN and UCN3 stimulation of PGs secretion were dependent on Gi/adenylyl cyclase (AC)/cAMP, NF-κB and MAPK signaling pathways. UCN2 suppression of PGs output was through Gs/AC/cAMP signaling pathways. Our data suggest that UCN, UCN2 and UCN3 can finely regulate PGs secretion via CRHR2, which facilitates the functional status of the uterus during pregnancy.
A 50-year-old woman with thyroid-stimulating hormone (TSH)-producing pituitary adenoma (TSHoma) was diagnosed due to symptoms of thyrotoxicosis. Preoperatively, she showed thyrotoxicosis with the syndrome of inappropriate secretion of TSH (SITSH) and had a 5 cm nodule in her thyroid gland. Octreotide was administered preoperatively, which helped lower her serum TSH level but not her thyroid hormone level. These findings were atypical for a patient with TSHoma. The TSHoma was completely resected, and the TSH level dropped below the sensitivity limit shortly after surgery. Interestingly, however, thyroid hormone levels remained high. A clear clue to the aetiology was provided by consecutive thyroid scintigraphy. Although preoperative thyroid scintigraphy did not show a hot nodule and the mass was thought to be a non-functional thyroid nodule, the nodule was found to be hot in the postoperative phase of TSH suppression. By focusing on the atypical postoperative course of the TSHoma, we were able to conclude that this was a case of TSHoma combined with an autonomously functioning thyroid nodule (AFTN).
The diagnosis of autonomously functioning thyroid nodules (AFTNs) depends on suppressed serum TSH levels. If thyroid hormones are resistant to somatostatin analogue therapy or surgery for TSHoma, complications of AFTN as well as destructive thyroiditis need to be considered. It is important to revisit the basics when facing diagnostic difficulties and not to give up on understanding the pathology.

Non-steroidal anti-inflammatory drugs (NSAIDs) are a common cause of renal damage, especially when taken together with angiotensin-converting enzyme inhibitors (ACE-i) or angiotensin II receptor blockers (ARBs) plus a diuretic - a combination known as the "triple whammy." New Zealand patients are at high risk of the "triple whammy" because they can easily purchase NSAIDs without a prescription and in nonpharmacy retail settings (eg, the supermarket), there is no legal requirement to include patient information sheets with medication, and direct-to-consumer drug advertising is permitted. A patient information package has been developed for those at greatest risk of the "triple whammy," consisting of a printable PDF and an interactive online learning activity. This information package aims to inform patients about their elevated risk of harm from NSAIDS and discourage use of NSAIDs. A randomized control trial was planned to assess the effect of the information package.
This study aims to pilot the trial pro trial. Response and drop-out rates will be reported for each trial arm. The numbers of patients who interact with the education package will be reported together with the patient evaluation of it.
Funding has been obtained from the Health Research Council of New Zealand (HRC 18-031). The University of Otago Human Research Ethics Committee (H21/016) has approved this trial. Consultation has been undertaken with The Ngai Tahu research consultation committee. The trial commenced on April 12, 2021.
This feasibility trial will test the study processes prior to commencing a randomized controlled trial and will determine the acceptability of the patient information package. We anticipate this work will provide useful information for other researchers attempting similar work.

Smart scales are increasingly used at home by patients to monitor their body weight and body composition, but scale accuracy has not often been documented.
The goal of the research was to determine the accuracy of 3 commercially available smart scales for weight and body composition compared with dual x-ray absorptiometry (DEXA) as the gold standard.
We designed a cross-sectional study in consecutive patients evaluated for DEXA in a physiology unit in a tertiary hospital in France. There were no exclusion criteria except patient declining to participate. Patients were weighed with one smart scale immediately after DEXA. Three scales were compared (scale 1 Body Partner [Téfal], scale 2 DietPack [Terraillon], and scale 3 Body Cardio [Nokia Withings]). We determined absolute error between the gold standard values obtained from DEXA and the smart scales for body mass, fat mass, and lean mass.
The sample for analysis included 53, 52, and 48 patients for each of the 3 tested smart scales, respectively. The median absolute error for body weight was 0.
