The performance of the WHO COVID-19 severity classification, COVID-GRAM, VACO Index, 4C Mortality, and CURB-65 prognostic scores in hospitalized COVID-19 patients: data on 4014 patients from a tertiary center registry.

AIM: To evaluate the predictive properties of several common prognostic scores regarding survival outcomes in hospitalized COVID-19 patients. METHODS: We retrospectively reviewed the medical records of 4014 consecutive COVID-19 patients hospitalized in our tertiary level institution from March 2020 to March 2021. Prognostic properties of the WHO COVID-19 severity classification, COVID-GRAM, Veterans Health Administration COVID-19 (VACO) Index, 4C Mortality Score, and CURB-65 score regarding 30-day mortality, in-hospital mortality, presence of severe or critical disease on admission, need for an intensive care unit treatment, and mechanical ventilation during hospitalization were evaluated. RESULTS: All of the investigated prognostic scores significantly distinguished between groups of patients with different 30-day mortality. The CURB-65 and 4C Mortality Score had the best prognostic properties for prediction of 30-day mortality (area under the curve [AUC] 0.761 for both) and in-hospital mortality (AUC 0.757 and 0.762, respectively). The 4C Mortality Score and COVID-GRAM best predicted the presence of severe or critical disease (AUC 0.785 and 0.717, respectively). In the multivariate analysis evaluating 30-day mortality, all scores mutually independently provided additional prognostic information, except the VACO Index, whose prognostic properties were redundant. CONCLUSION: Complex prognostic scores based on many parameters and comorbid conditions did not have better prognostic properties regarding survival outcomes than a simple CURB-65 prognostic score. CURB-65 also provides the largest number of prognostic categories (five), allowing more precise risk stratification than other prognostic scores.

Semaglutide might be a key for breaking the vicious cycle of metabolically associated fatty liver disease spectrum?

Metabolically associated fatty liver disease (MAFLD) is a liver manifestation of metabolic syndrome potentially related to unfavorable hepatic and extrahepatic outcomes and progression to cirrhosis. Up to date, there are no approved pharmacotherapies for the treatment of MAFLD, so management focused on lifestyle interventions to encourage weight loss, and treatment of coexisting conditions is the only available option. Unfortunately, the aforementioned is often not potent enough to offer reversal or slow down hepatic inflammation and fibrosis. Glucagon-like peptide-1 receptor agonists have a favorable effect on glycemic management and weight loss of patients with type 2 diabetes mellitus and recently published data suggest their potential in MAFLD treatment. In addition, some of the agents have proven cardiovascular and renal benefits in dedicated cardiovascular outcome trials, making them an interesting therapeutic option. In this opinion review, we discuss the role of semaglutide in MAFLD.

Gamma-knife radiosurgery in acromegaly: the results from the Croatian acromegaly registry.

PURPOSE: The aim of our study was to evaluate the efficacy and safety of Leksell gamma-knife radiosurgery in the treatment of residual growth hormone-secreting pituitary adenomas after the surgery. MATERIALS AND METHODS: We conducted a retrospective analysis of 23 acromegaly patients treated with gamma-knife radiosurgery between 1996 and 2019. The therapeutic success of radiosurgery was defined as IGF-1 normalization without suppressive medication (complete response) or as IGF-1 normalization with medication (partial response). RESULTS: The median follow-up was 57 (10-198) months. Complete response was achieved in 11 patients (47.8%) with actuarial remission rates of 17.4%, 26.1%, 39.1% and 47.8% at 1, 2, 4, and 7 years, respectively. The median time to complete the response was 21 (6-85) months. Partial response was achieved in another nine patients (39.1%) after a median time of 48 (6-144) months from radiosurgery. Patients who achieved complete remission had significantly lower IGF-1 levels before radiosurgery (p = 0.016) as well as smaller tumour volume (p = 0.016) and radiologically less invasive tumours (p = 0.022) in comparison to patients who did not achieve IGF-1 normalization. Tumour growth control after radiosurgery was established in all patients. During the follow-up, new hormone deficiencies were found in seven patients (30.4%) which corresponds to the incidence of one new case of hypopituitarism per 7.1 patient years. CONCLUSIONS: Gamma-knife radiosurgery offers endocrine remission and tumour growth control in a substantial proportion of patients with GH-secreting adenomas. Given the high cost of life-long medical treatment and a moderate risk of radiation-induced side effects, radiosurgery for growth hormone-secreting pituitary adenomas should be considered in all patients with residual tumours.
