Objective: To estimate the point prevalence of and risk factors associated with the development of pressure ulcers at a university hospital in Brazil.
Methods: This study was conducted on 196 participants using a structured questionnaire, physical examination of the skin, and the Braden scale. The Mann-Whitney U, χ2, or Fisher's exact tests were used to compare the participants and the associations of variables with pressure ulcers. A modified multivariate Poisson regression model was built considering the presence of pressure injuries and the independent variables.
Results: The point prevalence of pressure ulcers was 10.71% and was significantly associated with less than 12 years of schooling (p=0.0213), use of antihypertensive drugs during hospital stay (p=0.0259), diagnosis of systemic hypertension (p=0.0035), and diabetes mellitus. Lower scores on the Braden scale (p=0.0001) were positively associated with the presence of pressure ulcers. Furthermore, cardiovascular disease (p=0.0267) and diaper use (p=0.0001) were associated with the presence of pressure ulcers. Moreover, they were also associated with prolonged hospital stay, advanced age, less than 12 years of schooling, use of antihypertensive drugs, hypertension, diabetes, and lower Braden scale scores.
Conclusion: Health professionals should be aware of the risk factors associated with pressure ulcers, evaluate patient skin daily, and offer prevention. Our findings support the need to allocate resources for the prevention and treatment of pressure injuries.

Objectives: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide, particularly among the elderly, resulting in high rates of intensive care unit (ICU) admissions. Malnutrition is common in elderly patients and has been associated with poor prognosis in patients with COPD. However, its impact in the ICU setting remains incompletely defined.

Hypoxia, characterized by inadequate tissue oxygenation, may result in tissue damage and organ failure if not addressed. Current detection approaches frequently prove insufficient, depending on symptoms and rudimentary metrics such as tissue oxygenation, which fail to comprehensively identify the onset of hypoxia. The European Pressure Ulcer Advisory Panel (EPUAP) has recognized sweat lactate as a possible marker for the early identification of decubitus ulcers, nevertheless, neither sweat lactate nor oxygenation independently provides an appropriate diagnosis of hypoxia.

Colorectal cancer (CRC) is the third most common cancer globally. Therefore, this study aims to examine data from the National Health Insurance Sharing Service (NHISS) to investigate factors influencing colon cancer incidence, focusing on key variables and optimal cutoff points. The patient cohort from the NHISS database included 1,120,377 individuals aged 1-85 years.

Background: Loss or displacement of a fat pad on the foot increases plantar pressure, leading to pain and plantar ulcers. These ulcers, especially in patients with diabetic neuropathy, have high recurrence rates, often resulting in amputations. Standard of care focuses on reducing plantar pressure with shoe padding or orthotic devices, leaving the restoration of the fat pad as an unmet medical need.

Objective: Femoral neck fractures in the elderly are a global health issue, with the choice between cemented and uncemented hemiarthroplasty remaining a topic of debate. This systematic review and meta-analysis aims to compare the effects of the two surgical options on health-related quality of life (HRQoL), mortality, and functional outcomes.
Methods: We searched PubMed, Embase, and Cochrane databases for randomized controlled trials (RCTs) comparing cemented with uncemented hemiarthroplasty in patients aged 50 years and older with femoral neck fractures.
