URINARY BLADDER CANCER RECURRENCE AND EXPRESSION OF LYNCH AND HER MARKERS: SEARCHING FOR IMMUNOHISTOCHEMICAL PATTERNS AMONG 113 TUMORS FROM 33 PATIENTS.
The aim was to identify immunohistochemical (IHC) markers able to predict recurrence of urinary bladder tumors. The method of multivariate adaptive regression splines (MARS) was applied to IHC data of 33 patients with urinary bladder cancer that relapsed one to six times (24 male and nine female, age 57-87 years). The MARS analysis was used to predict the total number of recurrences and the Ki-67 value by nine IHC markers (epidermal growth factor receptor (EGFR), HER2, HER3, E-cadherin, Ki-67, MLH1, MSH2, MSH6 and PMS2). ⋯ The finding of E-cadherin was not found relevant by any of these MARS models. In conclusion, the MARS results associated multiple IHC markers with the number of recurrences and with Ki-67 values. It is important that differences in predictive markers were found between initial tumors and first recurrences, and between quick and slow recurrences, thus suggesting that tumor biology is different among these subgroups regarding the total number of recurrences and Ki-67 values.

EFFICACY OF A LIPID-LOWERING DIET ON KEY FATTY ACID RATIOS AND OMEGA-3 INDEX IN HYPERLIPIDEMIC SUBJECTS.
Polyunsaturated fatty acid (PUFA) dietary intake, status and serum key fatty acid (FA) ratios may aid in cardiovascular disease-related risk assessment. The aim of this study was to investigate the effects of lipid-lowering diet on key FA ratios in serum phospholipids and omega-3 index in erythrocyte phospholipids in moderately hyperlipidemic subjects. The study included 41 subjects, mean age 56±6 years. ⋯ Total cholesterol/high-density lipoprotein (HDL), low-density lipoprotein (LDL)/HDL and triacylglycerol/HDL-cholesterol ratios positively correlated with all FA ratios, and negatively correlated with total omega-3 levels in serum phospholipids and omega-3 index in erythrocytes. Total serum omega-3 levels showed strongest association with lipoprotein ratios and positive correlation with homeostatic model assessment (HOMA) index. In conclusion, lipid-lowering diet resulted in decreased serum key FA ratios, increased omega-3 levels, and improved insulin sensitivity that may lead to a lower risk of cardiovascular disease in subjects with moderate hyperlipidemia.

SYSTEMIC INFECTION WITH SINGLE OR MULTI-ORGAN DAMAGE CAUSED BY INADEQUATELY MANAGED CHRONIC WOUNDS: A CASE SERIES.
Chronic wounds are often underestimated condition with increasingly growing inpatient and outpatient treatment costs. Since the patient population affected by chronic wounds is heterogeneous and includes diabetes, chronic venous insufficiency and peripheral artery disease patients, with additional differences in gender, age, previous medical history, treatment of chronic wounds is highly personalized and dependent on a variety of factors. ⋯ Each of the patients had a significant worsening of their chronic wounds during the COVID-19 pandemic: either following an active SARS-CoV-2 infection or due to the limited access to primary care. The cases described here highlight the necessity of providing proper and regular care for all patients during the COVID-19 pandemic, regardless of the current state of the healthcare system and the adversities and hurdles it currently faces, to prevent the pandemic from becoming a syndemic.

Review Case ReportsMETHEMOGLOBINEMIA - A CASE REPORT AND LITERATURE REVIEW.
The objective of this case report is to present a patient with acquired methemoglobinemia due to poisoning of an unknown cause. A 55-year-old man was brought to the Emergency Department, University Hospital Center Zagreb, with an unwell appearance, cyanotic, restless, and presented with a quantitative consciousness disorder. An initial assessment showed decreased oxygen saturation (SpO2 85 [%]), while point-of-care arterial blood gas (ABG) analysis assessed normal partial pressure of oxygen (pO2). ⋯ Methemoglobinemia symptoms are the results of inadequate oxygen transport. The diagnosis was confirmed by co-oximetry, while three clinical entities suspected methemoglobinemia: refractory hypoxia, "cyanosis-saturation gap" and dark brown blood. This paper reports our patient's clinical presentation, discusses the causes and mechanisms of possible poisoning, and reviews recent guidelines for methemoglobinemia management.

ReviewPERIPHERAL NERVE BLOCKS FOR HIP FRACTURES IN EMERGENCY MEDICINE.
Hip fractures represent a major public health issue with increasing incidence as a population ages. The aim of this review is to describe peripheral nerve block techniques (the fascia iliaca compartment block and the pericapsular nerve group block) as pain management for hip fractures in emergency medicine, and to emphasize their benefits. Hip fractures are extremely painful injuries. ⋯ Peripheral nerve blocks for hip fractures are safe and effective, also in emergency medicine settings. The benefits for patients are greater pain relief, especially during movement, less opioid requirements and decreased incidence of delirium. Regional analgesia should be routinely used in hip fracture pain management.
