Fibrotic-like abnormalities are present in 60% of a single-center, longitudinal, multi-ethnic cohort 3-years after severe COVID-19. They are independently associated with male sex, low BMI, shorter telomere length, increased severity of illness, and mechanical ventilation; Black race and asthma are protective. Participants with fibrotic-like abnormalities are more likely to have reduced diffusion capacity and 6-minute walk distance.

Article Synopsis
  • MRSA infections pose a significant public health challenge, prompting the need for new treatment strategies beyond conventional antibiotics.
  • The study explored the effects of TRP ion channel inhibitors on MRSA skin infections in mice, finding that blocking TRPA1 reduced infection severity, while TRPV1 deletion had no significant impact.
  • The research revealed that inhibiting TRPA1 influenced protein expressions and metabolic pathways related to inflammation and immune response, suggesting TRPA1 antagonism could be an effective, low-cost treatment option for MRSA.

Article Synopsis
  • The study investigates the long-term risk of damage to the right coronary artery (RCA) after patients undergo radiofrequency ablation (RFA) for atrial flutter related to the cavotricuspid isthmus (CTI).
  • A comparison was made between patients who had CTI RFA and those who only received ablation for atrial fibrillation (AF), with coronary angiography performed afterward to evaluate any differences in RCA stenosis.
  • Results indicate that there were no significant differences in the incidence or severity of RCA stenoses between the two groups, suggesting that CTI RFA does not increase the risk of RCA damage in the long term.

Background: Eliminating financial barriers and improving healthcare accessibility pertain to be key elements of the United Nation's sustainable development goals. These have directed health policymakers to advocate private health insurance as a health promotion strategy to enable patients to obtain absolute and affordable medical care when needed. Against this backdrop, the current study investigates the coverage trend and financial risk-protective nature of private health insurance plans.

Article Synopsis
  • The article explores the development of the anesthesia assistant (AA) profession in Canada, highlighting its growth over the last 50 years since its formal recognition in Quebec and 15 years in other provinces.
  • Data was collected from 19 institutions across 8 provinces regarding factors such as recruitment, training, credentialing, and roles, revealing significant variations in AA responsibilities influenced by provincial health care governance.
  • The findings indicate that while AAs play a crucial role in anesthesia care, including equipment maintenance and supporting anesthesiologists, there is a lack of standardized metrics for assessing patient safety and operational efficiency in their practices across Canada.

Porous materials have recently attracted significant attention in the aerospace and biomedical fields for addressing issues related to friction and wear. Porous materials are beneficial in applications where continuous lubrication is not feasible or for components that operate under extreme conditions, such as high speeds, elevated temperatures, and heavy loads. The pores can serve as reservoirs for liquid lubricants, which are gradually released during the operation of the components.

Background: High-frequency, low-tidal volume (HFLTV) ventilation increases the efficacy and efficiency of radiofrequency catheter ablation (RFCA) of paroxysmal atrial fibrillation. Whether those benefits can be extrapolated to RFCA of persistent atrial fibrillation (PeAF) is undetermined.

Objective: The purpose of this study was to evaluate whether using HFLTV ventilation during RFCA in patients with PeAF is associated with improved procedural and long-term clinical outcomes compared to standard ventilation (SV).

  • Many COVID-19 survivors from the early pandemic showed signs of cardiac injury, prompting investigations into long-term heart effects using cardiac imaging techniques like CMR and TTE.
  • A study involving 40 COVID-19 survivors and 12 matched controls conducted TTE and CMR at an average of 308 days post-infection, revealing no significant differences in heart structure, function, or tissue abnormalities between the groups.
  • The findings suggest that there is no lasting damage or inflammation to the heart in these survivors, despite previous reports of cardiac issues during acute COVID-19.

Background: Better understanding of the interaction between metabolism and immune response will be key to understanding physiology and disease. Tumor Necrosis Factor-alpha (TNFα) has been studied widely. However, despite the extensive knowledge about TNFα, the cytokine appears to induce not only variable, but often contradictory, effects on inflammation and cell proliferation.

Good glycemic control is the aim of managing type 2 diabetes mellitus (T2DM) which is crucial for the prevention of long-term complications in individuals with T2DM. The aim of this study was to identify the factors associated with good glycemic control in individuals with T2DM following up at a rural health-care facility (HCF) in Goa. A cross-sectional study was conducted among 120 individuals with T2DM who regularly followed up at a rural HCF in Goa.

  • The study evaluated the safety and effectiveness of radiofrequency catheter ablation (RF CA) for treating paroxysmal atrial fibrillation (PAF) using a real-world multi-center registry approach.
  • A total of 2,470 patients were assessed, with most procedures performed without fluoroscopy, achieving an 81.6% success rate in preventing all forms of atrial arrhythmias after one year.
  • The findings highlight that modern techniques and protocols in RF CA lead to positive clinical outcomes and a low complication rate of 1.9%.

Background: Reversal of ileostomy is associated with morbidity including wound infection and prolonged wound healing. Negative pressure wound therapy (NPWT) has been shown to reduce time to wound healing by secondary intention. The aim of this study was to determine whether NPWT improved wound healing rates, compared with simple wound dressings, in patients undergoing reversal of ileostomy where the skin wound is closed with a purse-string suture.

We conducted a prospective single-centre cohort study of 104 multi-ethnic severe COVID-19 survivors from the first wave of the pandemic 15 months after hospitalisation. Of those who were assessed at 4 and 15 months, improvement of ground glass opacities correlated with worsened fibrotic reticulations. Despite a high prevalence of fibrotic patterns (64%), pulmonary function, grip strength, 6 min walk distance and frailty normalised.
