AI Article Synopsis

  • - The study aimed to analyze the trends in hospitalizations due to systemic and cardiac amyloidosis in the Veneto Region of Northeastern Italy from 2010 to 2020, highlighting the need for better understanding of its epidemiology.
  • - Using ICD-9 codes, the researchers found that the incidence of amyloidosis-related hospitalizations increased significantly, particularly among older male patients (>65 years), with an annual increase of 17% from 2015 to 2020.
  • - By 2020, a majority (about 70%) of the hospitalized cases involved cardiac amyloidosis, and there was also a notable connection between patients undergoing carpal tunnel syndrome surgeries and subsequent cardiac issues, especially in men. *

Article Abstract

Aim: Defining the epidemiology of systemic and cardiac amyloidosis (CA) is a contemporary challenge. The present study aimed to estimate incidence and time trends in amyloidosis-related hospitalizations (AH) in Veneto Region (5 million inhabitants, Northeastern Italy).

Methods: International Classification of Diseases (ICD-9) codes were used to identify AH in Veneto from 2010 to 2020. AH were defined as any hospitalization with a discharge summary reporting an ICD-9 code for systemic amyloidosis. Hospitalization for CA was defined as records with ICD-9 code for systemic amyloidosis and ICD-9 code for heart failure,cardiomyopathy or arrhythmia. Hospital/outpatient encounters for carpal tunnel syndrome (CTS) surgeries also were extracted. AH incidence was estimated using a buffer of 5 years.

Results: In the time range 2015-2020, the incidence rate of AH was 23.5 cases per 10 (95% confidence interval, CI, 21.8; 25.3), mainly affecting patients>65 years (76.2%) and males (63.5%), with a progressively increasing trend (percent annual increase 17%, 95% CI 12; 22%). The 10 year prevalence of AH in 2020 was 124.5 per 10 (95% CI 114.9; 134.8). In 2020, annual hospitalized prevalent cases of CA were about 70% of all cases (159/228), mainly patients >65 years and males. Among patients with multiple CTS surgeries, a subsequent code for cardiac disease was found in 913 after a median of 3.9 years, more frequently in men than in women (463/6.526 7.1% versus 450/11.406 3.9%).

Conclusions: In Veneto, we recorded a significantly increasing trend in the incidence of AH, with concordant increasing prevalence estimates.

Patients admitted to intensive care unit (ICU) after non-traumatic subarachnoid hemorrhage (SAH) represent a group with distinctive characteristics and few data are available on long-term outcome in this population. We conducted a single-center retrospective study in an Italian intensive care unit. All patients with non-traumatic SAH (ICD-9-CM Diagnosis Code 430) admitted to ICU were included.

The comorbidity cycle between psoriasis and addictions remains unclear. The study aimed to investigate the cumulative incidence of addictions in psoriasis patients and controls in the Stockholm Psoriasis Cohort (SPC). The SPC is an observational cohort study that enrolled psoriasis patients between 2001 and 2005 and matched controls using the Swedish Total Population Register.

Introduction: George Floyd's death in 2020 galvanised large protests around the country, including the emergence of the Capitol Hill Autonomous Zone (CHAZ) in Seattle, Washington, a non-policed, organised protest region that may have differing injury risks than other regions. We sought to quantitatively describe characteristics of injuries related to protests documented at visits to two nearby major emergency departments, including the only Level 1 trauma centre in the state.

Methods: Using the International Classification of Diseases, 10th Revision code inclusion criteria, we identified 1938 unique patient visits across the two emergency departments from 29 May 2020 and 1 July 2020.
