AI Article Synopsis

  • The study examines how the COVID-19 lockdown affected the recovery of patients undergoing total knee arthroplasty (TKA), with a specific focus on postoperative outcomes like pain and mobility.
  • Researchers compared 41 patients who had TKA during the lockdown to 47 patients who had the procedure prior to the pandemic, analyzing several health indicators such as the WOMAC score and length of hospital stay.
  • Results showed that the lockdown group had significantly worse recovery outcomes after six months, highlighting the need for better physiotherapy protocols during potential future lockdowns to ensure optimal postoperative care.

Article Abstract

Introduction: To help combat the SARS-CoV-2 (COVID-19) pandemic, elective inpatient procedures have been reduced. The authors hypothesized that a nationwide lockdown would negatively affect the postoperative outcome after total knee arthroplasty (TKA) due to reduced physiotherapy as well as restrictions in external facilities of physiotherapy and rehabilitation.

Materials And Methods: We conducted a retrospective, comparative study including 41 patients who had undergone primary TKA during the first lockdown of the COVID-19 pandemic from March 2020 to April 2020 and a comparable control group consisting of 47 patients with a minimum follow-up of 6 months before the COVID-19 pandemic from 2019. Relevant end points were the visual analogue scale (VAS) for pain, Knee Society Function Score (KSS), Oxford Knee Score (OKS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and range of motion (ROM).

Results: The lockdown group had a significantly worse outcome compared to the control group 6 months after TKA regarding WOMAC (p = 0.001), KSS (p < 0.001), OKS (p < 0.001), and length of hospital stay (p < 0.001). We found no statistically significant difference between the groups in ROM (p = 0.132), KSFS (p = 0.933), VAS at rest (p = 0.9.22), and exercise (p = 0.304).

Conclusion: The COVID-19 pandemic negatively affected early clinical outcome parameters of elective primary TKA at 6 months of follow-up due to restrictions in postoperative care. We believe that standardized protocols for physiotherapy will improve clinical outcomes for TKA in the event of future lockdowns and underline the importance of appropriate postoperative care during this pandemic.

Introduction: Nadezhda Clinic is a free student-run health clinic that provides culturally sensitive primary care services to the underserved Russian-speaking population of the greater Sacramento area. At the onset of the COVID-19 pandemic, the clinic suspended in-person services and solely offered telemedicine visits. Most patients were hesitant to utilize telemedicine due to poor technological literacy, privacy concerns, and a preference for in-person care.

Introduction: Home care workers (HCWs) are paid caregivers who provide support to patients with chronic conditions and functional limitations. Additionally, they provide emotional support to patients and familial support. Although several qualitative studies have been conducted on HCWs, they focused more on studying prevalently the lived experiences about the workplace violence, the end of life, stressor and resilience, during the COVID-19 pandemic or focused more in dementia and heart failure, but not on feelings and working conditions.

Aim: To investigate the detection and initial management of first psychotic episodes, as well as established schizophrenia, within the primary care of the Andalusian Health System.

Background: Delay in detecting and treating psychosis is associated with slower recovery, higher relapse risk, and poorer long-term outcomes. Often, psychotic episodes go unnoticed for years before a diagnosis is established.

Purpose: This study aimed to evaluate the long-term impact of mild COVID-19 infection and COVID-19 vaccination on ovarian function in patients undergoing assisted reproductive technology (ART). Specifically, we assessed ovarian outcomes between 9 and 18 months post-infection and investigated the effects of COVID-19 vaccines (inactivated virus and adenovirus) on reproductive parameters.

Methods: The study included two objectives: (a) examining ovarian function in post-COVID-19 patients (9-18 months post-infection) compared to a control group and (b) comparing reproductive outcomes in vaccinated versus unvaccinated patients.
