Background: Implant-simulation software can now be used to improve treatment planning, guide surgery, and ensure more accurate implant placement.
Purpose: The aim of this study was to evaluate the outcome of a guided surgery protocol versus a conventional protocol.
Materials And Methods: Twenty-six patients were randomly assigned to Guided Surgery or Conventional Surgery. In test group implants were placed in the maxilla using a tooth supported model-based surgical guide with a minimally invasive flap and immediately loaded. In control group implants were inserted with an open flap surgery following a prosthetic stent and immediately loaded.
Results: A total of 70 implants were placed (36 test and 34 control). Statistically significant differences were found between the test group and the control group for patient opinion about self-confidence, assumption of analgesic tablets and perceived pain. The test group registered a statistically significant reduction (p < .05) as regards time of surgery and time of provisional insertion with respect to the control group.
Conclusions: Implants can successfully integrate in the posterior maxilla using a guided surgery approach with immediate loading. The use of guided surgery helped to reduce the surgery duration, pain intensity, related analgesic consumption, and a more predictable provisional installation.

Background: The Sino-nasal Outcome Test (SNOT-22) is a 22-question survey that is utilized to evaluate health-related quality of life of patients with chronic rhinosinusitis (CRS). The Patient Global Impression Symptom Severity (PGISS) is a similar yet versatile instrument that combines features of both a Likert scale and a visual analog to assess symptom severity in CRS patients. While previous studies have evaluated the validity of SNOT-22 as an instrument to measure CRS patients' symptom severity, no studies have evaluated PGISS scale's ability to evaluate and guide treatment plans for CRS patients.

Purpose Of The Study: Open (incisional) biopsies have long been accepted as the gold standard in diagnosing bone and soft tissue tumors. However, the main disadvantage of this method is that it can lead to increased contamination, hematoma, infection, and pathological fracture. Compared to open biopsies, percutaneous core needle biopsies are less invasive, do not require hospitalization, have low costs and low complication rates, and there is no need for wound healing in cases that require radiotherapy.

Objective: Coronary artery disease (CAD) remains a significant global health burden, characterized by the narrowing or blockage of coronary arteries. Treatment decisions are often guided by angiography-based scoring systems, such as the Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) and Gensini scores, although these require invasive procedures. This study explores the potential of electrocardiography (ECG) as a noninvasive diagnostic tool for predicting CAD severity, alongside traditional risk factors.

Purpose: Appropriate opioid management is crucial to reduce opioid overdose risk for ICU surgical patients, which can lead to severe complications. Accurately predicting postoperative opioid needs and understanding the associated factors can effectively guide appropriate opioid use, significantly enhancing patient safety and recovery outcomes. Although machine learning models can accurately predict postoperative opioid needs, lacking interpretability hinders their adoption in clinical practice.
