Ligand Rearrangement Brings about Tetrahydrothiophene-Functionalized D,S-Heterocyclic Carbene Palladium(Two) Processes.
The combination of molecular data and morphological differences between this and other species of Myxobolus Bütschli, 1882 lead us to propose that the present form be established as a new species, M. allami. The present study also provides more evidence for the idea that caudal appendages cannot be reliably used to distinguish the species of the genera Myxobolus and Henneguya Thélohan, 1892.
The risk of differentiated thyroid cancer (DTC) recurrence is widely evaluated according to the 2015 ATA Risk Stratification System. Topography of malignant nodules has been previously reported as an additional risk factor but is not included in the ATA system. Thus, our study aimed to evaluate the relationship between DTC topography and response to initial therapy.

We enrolled 401 low- to intermediate-risk patients with DTC who had undergone thyroidectomy and radioiodine therapy. DTC topography was recorded and compared with the response to therapy as assessed 12 months after the end of therapy.

Overall, 366/401 (91.3%) patients had an excellent response to initial therapy while 22/401 (5.5%) and 13/401 (3.2%) had incomplete biochemical or structural responses, respectively. see more Incomplete response occurred in 10/36 (27.8%), 5/125 (4.0%), and 4/111 (3.6%) patients whose unifocal malignant nodules were located in the isthmus, right lobe, or left lobe. Incomplete response was also observed in 4/54 (7.4%) andor for having both persistent disease 12 months after primary treatment and reduced DFS.
Several studies showed the occurrence of vertebral fracture (VFx) in patients discontinuing denosumab (Dmab), suggesting the need of bisphosphonate (BPs) therapy to mitigate this VFx risk increase. However, the morphometric VFx (morphoVFx) incidence after Dmab discontinuation and the BPs effect on VFx risk in this setting are still a matter of debate.

Retrospective, monocentric study.

In 120 patients (111 females) discontinuing Dmab, 19 have not been treated (non-treated group 16 females, aged 63.5 ± 15.0 years) and 101 patients have been treated (treated group 95 females, aged 70.0 ± 10.6 years) with BPs (28 alendronate (ALN); 73 zoledronate ZOL), single infusion), respectively. We evaluated the incidence of both clinical VFx and morphoVFx in treated group and non-treated group.

Patients in treated group showed a 5.5% VFx incidence (n = 6, three clinical, three morpho VFx), which was anyway lower than non-treated group patients (n = 4, 21.1%, four clinical, three multiple, P = 0.029), despite a comparable FRAX score at the time of Dmab initiation. The logistic regression analysis showed that the VFx incidence was independently associated with the lack of BPs treatment (odds ratio 13.9, 95% CI 1.7-111.1, P = 0.014), but not with the number of Dmab injections, age, duration of BPs before Dmab initiation, the BMD at Dmab withdrawal, and the prevalence of VFx at Dmab withdrawal.

The Dmab withdrawal is associated with an increased risk of clinical but not morphometric VFx. Therapy with ALN or with a single ZOL treatment is partially effective in reducing the increased VFx risk after Dmab withdrawal.

Primary aldosteronism (PA) is the most common form of secondary and curable hypertension. Different germline and somatic mutations are found in aldosterone-producing adenoma (APA) and familial forms of the disease, while the causes of bilateral adrenal hyperplasia (BAH) remain largely unknown. Adrenalectomy is the recommended treatment for patients with APA; however, 6% of patients are not cured and show persistent PA after surgery suggesting BAH. The objective of this study was to analyze clinical data of patients with APA without biochemical success after adrenalectomy as well as the histological and genetic characteristics of their adrenal glands.

Clinical data of 12 patients with partial and absent biochemical cure were compared to those from 39 PA patients with hormonal cure after surgery. Histological, morphological, and genetic characterization of the adrenals was carried out by CYP11B2 and CYP11B1 immunostaining and by CYP11B2-guided NGS.

Patients with absent hormonal cure displayed a longer durnisms underlying BAH and APA.
Thyroid surgery may lead to postoperative complications. The aim of this paper was to determine whether the rate of postoperative hypoparathyroidism (HPT) is influenced by whether surgery is staged.

Single-institution retrospective observational study.

The clinical records of 786 patients treated at the Otolaryngology Unit of the Azienda USL-IRCCS di Reggio Emilia between January 1990 and December 2015 were reviewed. Patients were divided into two groups according to the surgical treatment received group TT (637 patients, 81.04%) underwent single-stage total thyroidectomy; Group cT (149 patients, 18.96%) underwent loboisthmusectomy and delayed completion total thyroidectomy. Transient and permanent HPT, assessed after 6 months of follow-up, were the primary endpoints. Risk factors of postoperative HPT were also analysed as secondary outcomes.

Rates of transient HPT in group TT were higher than those observed in group cT, (P = 0.0057). Analysis of risk factors identified sex as an independent risk factor for transient HPT only for group TT (P = 0.0012) and the number of parathyroid glands remaining in situ (PGRIS) as an independent risk factor for transient and permanent HPT for group TT (P < 0.0001 and P = 0.0002, respectively).

This study suggests that the risk of transient postoperative HPT is lower in patients that undergo completion thyroidectomy. Further independent risk factors for postoperative HPT are female sex and PGRIS score. In light of the growing use of conservative surgery for thyroid neoplasms, these findings could help to adequately plan surgery in order to reduce endocrine complications.
