Little is known about the effect of renin angiotensin aldosterone system-inhibiting (RAASi) drugs on alternative angiotensin peptides (APs) such as angiotensin 1-7 (Ang1-7), which are mediated by angiotensin-converting enzyme 2 (ACE2).
Angiotensin receptor blockers (ARBs) would alter balance of APs and differences would be magnified in vitro by incubation of plasma samples with recombinant human ACE2 (rhACE2).
Six cats with cardiomyopathy (CM), 8 healthy cats.
Prospective open label trial. Plasma equilibrium concentrations of APs were measured in healthy cats as well as in CM cats that first received no RAASi drugs (CM
) and then after 14 days of PO telmisartan (CM
). Plasma APs also were measured after in vitro incubation with rhACE2.
No significant differences were found between healthy and CM
groups. Concentrations of several APs, including angiotensin I (AT1) and angiotensin II (AT2) were significantly different between CM
and CM
groups. Incubation with rhACE2 decreased AT1 and AT2 in both groups. The geometric mean concentration of Ang1-7 was significantly higher in CM
(4.9 pg/mL; 95% confidence interval [CI], 3.7-6.4 pg/mL) vs CM
(3.2 pg/mL; 95% CI, 2.2-4.7 pg/mL; P = .01) and in CM
+ ACE2 (5.0 pg/mL; 95% CI, 3.9-6.4 pg/mL) vs CM
+ ACE2 (3.0 pg/mL; 95% CI, 1.7-5.5 pg/mL; P = .01). The most favorable theoretical AP profile that maximized Ang1-7 and other alternative APs was CM
+ ACE2.
Balance between traditional and alternative APs can be favorably shifted using ARBs and in vitro incubation with rhACE2. These data shed light on new AP-targeting strategies in cats with CM.

Significant health disparities exist between Māori and non-Māori patients in New Zealand. Māori patients treated medically for their thyroid disease are less likely to be euthyroid. The prevalence of thyroid disease and characteristics of Māori presenting for thyroid surgery has not been well studied. We aim to assess the differences in ethnic representation for thyroid surgery.
A retrospective analysis of cases performed between 2009 and 2019 at the Otolaryngology/Head and Neck Department in Waikato District Health Board (DHB) was completed. All patients who received a thyroid operation were included and divided into Māori and non-Māori groups. Clinical and operation notes were reviewed and the duration of presenting symptoms, weight, volume and diagnosis of the thyroid gland were assessed.
A total of 93 patients were included in our study, of whom 71 patients were female and 22 male with 37 being Māori and 56 non-Māori. Māori patients had significantly higher rates of retrosternal extension, compressive symptoms, post-operative complications, delayed presentation and larger thyroid goitres when compared to non-Māori (P < 0.05).
Our study confirms that there is a significant ethnic disparity for Māori patients requiring thyroid surgery. This highlights an additional poor health outcome for Māori compared to non-Māori patients.

The first case was seen in Turkey on March 11, and the World Health Organization (WHO) declared a pandemic on March 12, 2020. The study aimed to document the effect of pandemic on dermatology outpatient clinics in Turkey. Fifteen tertiary hospitals from 13 provinces were included in the study, which was conducted between January 12 and May 12, 2020. The International Codes of Diseases (ICD-10) categories and patients' characteristics were evaluated before and after the pandemic. A total of 164 878 patients, 133 131 before and 31 747 after the pandemic, were evaluated. The daily hospital applications were found reduced by 77%. click here The three of the most frequent diagnoses; dermatitis, acne, and psoriasis remained unchanged after the pandemic. While the frequency of herpes zoster, scabies, urticaria, pityriasis rosea and sexually transmitted diseases increased significantly; allergic and irritant contact dermatitis decreased after the pandemic. The applications regarding cutaneous neoplasms were considerably reduced during the pandemic, and this effect was more pronounced in cities with higher COVID incidence. The pandemic caused a noteworthy reduction in the number of patients accessing dermatological care. The pandemic caused significant changes in the frequency of a wide range of dermatological diseases. The application of cutaneous neoplasms is considerably reduced after the pandemic, and this effect was more pronounced in cities where pandemics are frequent. Therefore, the pandemic has resulted on numerous impacts on many critical issues in dermatology and dermatological care.Over the past few decades, the tricuspid valve (TV) interventions have been relatively lower compared to other cardiac valvular disease in terms of pathophysiology and management, especially regarding surgical intervention and therapy. However, recent crucial advances in assessment and management of the TV disease have resulted in a renewed interest in the "forgotten valve." The medical treatment aims to cure the underlying disease and address the presentation of the right heart failure. Surgical interventions have proven to yield good outcomes for those for whom surgery is indicated. For those who are not suitable for surgery, transcatheter surgery may prove to be a suitable replacement. Best practice with regard to surgical techniques is still in question due to limited data. This has been slowing the introduction of transcatheter interventions into common practical guidelines. The aim of this literature review is to discuss new insights on the pathophysiology, diagnosis, and interventions of TV disease, highlighting the surgical management and emerging transcatheter therapies.
