Two hundred thirty-seven subjects declared having difficulties with meal preparation at least once, and 133 declared having difficulties shopping. Subjects reporting any meal-related difficulties were older (p  less then  0.001), had more depressive symptoms (p  less then  0.001), and a lower physical function (p  less then  0.001) compared to those without difficulties. They also had a lower cognitive score (preparing meals p  less then  0.001; shopping p = 0.005) and a lower body mass index (preparing meals p = 0.005; shopping p = 0.023) at the end of the study. Meal-related activities were not associated with weight loss in unadjusted analysis and after adjustment for sex, age, depression, physical and cognitive status. CONCLUSION Difficulties preparing meals and shopping had no effect on weight loss in community-dwelling older people, despite their association with advanced age, functional decline, and depressive symptoms. BACKGROUND Necrotizing enterocolitis (NEC) is a gastrointestinal emergency characterized by ischemic necrosis of the intestinal mucosa, leading to bacterial translocation and pneumatosis of the bowel wall. Although there are numerous studies on clinical presentations of preterm NEC, approximately 10-15% of cases occur in full-term neonates. Nearly 10% of all infants with NEC will develop a rapidly progressive and fatal form of the disease called NEC totalis. CASE REPORT A 24-day-old term male infant presented to the Emergency Department (ED) with emesis. The infant was ill-appearing with a tense abdomen and had significant tachycardia and hypotension. The patient was immediately volume resuscitated and started on empiric antibiotics. Initial radiographs revealed no evidence of bowel obstruction or pneumatosis. Pediatric Surgery was consulted, and upper gastrointestinal and abdominal computed tomography scans were obtained, which were nondiagnostic. The patient was taken to the operating room for an exploratory laparotomy after continued clinical deterioration and was diagnosed with NEC totalis and passed away within 6 days. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS? This case demonstrates an uncommon presentation of NEC in an otherwise healthy term neonate without any known risk factors. The diagnosis of NEC is challenging because imaging studies may be inconclusive, particularly early in the clinical course. Regardless of the etiology, all infants who present to the ED with signs and symptoms of severe gastrointestinal distress should be treated with basic emergency care, including rapid fluid resuscitation, empiric antibiotics, bowel decompression, and early surgical consultation. BACKGROUND It is vital for frontline emergency physicians to immediately recognize the signs and symptoms of measles to initiate appropriate therapy and prevent spread to the health care team and other patients. OBJECTIVE This review serves as a clinically practical updated reference for when the differential diagnosis includes measles. DISCUSSION Measles is a highly contagious illness that classically presents with a rash, fever, cough, coryza, and conjunctivitis. Cases in the United States since 2000 have been attributed mainly to travelers who are infected abroad and then spread the illness to small, susceptible populations within the United States. Complications from measles are relatively common and can be associated with significant morbidity and mortality. Clinical suspicion should be confirmed with laboratory testing, which is most commonly a serum immunoglobulin M. The management of measles is mainly supportive. Patients that require more aggressive management include those who are pregnant, immunocompromised, or unvaccinated. Treatment may consist of the measles vaccine, intravenous immunoglobulin, vitamin A, and even ribavirin. Additionally, special precautions are required by hospital workers to help prevent the spread of the virus, which include N-95 masks and patient isolation in an airborne infection isolation room. CONCLUSION Emergency physicians must be readily able to identify, contain patients with suspected measles, and determine who will need further medical management for this potentially life-threatening illness. As this public health crisis evolves, novel ways of screening for and reporting cases of measles is needed. BACKGROUND Acetazolamide has been studied extensively in post-hypercapnic alkalosis as a tool to facilitate ventilator weaning in chronic obstructive pulmonary disease (COPD). It has also been utilized to facilitate respiratory drive in nonmechanically ventilated patients with COPD. Although this is generally a forgiving intervention, providers must carefully select patients for this medication, as it can cause severe acidosis and deterioration of clinical status in severe COPD cases. The present report describes two cases of patients who developed worsening acidosis and hypercapnia after receiving acetazolamide in acute respiratory failure. CASE REPORT Case 1 was a 72-year-old obese male with COPD who was dependent on supplemental oxygen and presented to the emergency department (ED) with acute on chronic hypercapnic respiratory failure. He was given a one-time dose of acetazolamide in the ED for "respiratory failure made worse by severe metabolic alkalosis." His arterial blood gas (ABG) worsened overnight, accompanied by decreased mental status pH 7.32, paCO2 82 mm Hg, paO2 50 mm Hg, HCO3 41.7 mmol/L, FiO2 32% to pH 7.21, paCO2 91.7 mm Hg, paO2 59 mm Hg, HCO3 36.6 mmol/L, and FiO2 32%. Case 2 was a 62-year-old male with COPD who was dependent on supplemental oxygen and presented to the ED with acute on chronic hypercapnic respiratory failure. He was given acetazolamide in the ED with similar results ABG on presentation pH 7.37, paCO2 79.3 mm Hg, paO2 77.6 mm Hg, HCO3 45.5 mmol/L, and FiO2 32%. The next morning, ABG was pH 7.29, paCO2 79 mm Hg, paO2 77 mm Hg, HCO3 45.5 mmol/L, and FiO2 32%. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS? Acetazolamide given early in the uncompensated setting can worsen acidosis and potentiate clinical deterioration. BACKGROUND Pseudoaneurysms of the foot are rare and can occur from a range of etiologies, including laceration from a foreign body. The majority of reported cases have been diagnosed by computed tomography, magnetic resonance imaging, or angiography. These tests require intravenous access and contrast, confer radiation, take time to perform and interpret, are expensive, and are not always readily available in the acute setting. No prior reported pseudoaneurysms of the foot have been diagnosed by point-of-care ultrasound (POCUS). CASE REPORT An 8-year-old boy presented to the emergency department for evaluation of left foot pain and swelling 2 weeks after stepping on small pieces of broken glass. He had a 3 × 3 cm area of painful swelling and erythema at the medial plantar aspect of his foot. A cutaneous abscess was the working diagnosis and preparations were made for an incision and drainage procedure. However, POCUS revealed a medial plantar artery pseudoaneurysm. Incision and drainage would have led to unexpected arterial bleeding. Instead, the pediatric surgery service was consulted for pseudoaneurysm excision and arterial ligation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS? Incision of a pseudoaneurysm in the sole of the foot-thought to be an abscess based on clinical examination-would lead to unforeseen arterial bleeding. POCUS at the bedside can differentiate between simple abscess and pseudoaneurysm in order to guide appropriate and time-sensitive management. Historical and clinical clues to the diagnosis may include heavier-than-expected bleeding at the time of laceration and a pulsatile quality to the painful erythema and swelling. PURPOSE To evaluate the clinical outcomes of patients who underwent biologically enhanced patch augmentation repair for the treatment of revision massive rotator cuff tears. METHODS Twenty-two patients who underwent arthroscopic and mini-open rotator cuff repair using a patch augmented with platelet-rich plasma and concentrated bone marrow aspirate (cBMA) for revision massive (≥2 tendons) rotator cuff tears from 2009 to 2014, with a minimum 1-year follow-up, were included in the study. In this procedure the medial side of the graft is secured to the rotator cuff tendon remaining medially. American Shoulder and Elbow Surgeons (ASES), Simple Shoulder Test, and postoperative Single Assessment Numerical Evaluation scores were evaluated. Blasticidin S Selection Antibiotics for Transfected Cell inhibitor To determine the clinical relevance of ASES scores, the minimal clinically important difference, substantial clinical benefit (SCB), and the patient-acceptable symptomatic state (PASS) thresholds were used. Clinical success or failure was defined based on whether the patient reachentation repair reached substantial clinical benefit, whereas 32% reached or exceeded the PASS criteria. LEVEL OF EVIDENCE Case Series Level IV. Electronic nicotine delivery systems and vaping devices are now the most commonly used forms of tobacco consumed by youth and young adults. A variety of chemicals and toxicants released during inhalation have harmful systemic effects and effects on the lung. The known and potential health consequences are particularly alarming. There is concern that use of these devices will create a new generation of life-long smokers with nicotine and polysubstance addiction. Beyond the concerning chronic health effects of regular use, there is a recent epidemic of severe, acute lung disease termed e-cigarette, or vaping product use-associated lung injury, (EVALI), associated with high morbidity and mortality. These issues demand immediate public health attention. Healthcare providers play key roles in limiting the exposure of youth and young adults to these products by providing evidence-based counseling to patients and families, and by advocating for regulations to protect against childhood initiation and continuation of use. PURPOSE To compare fetal ultrasound measurements performed by two observers with different levels of experience and evaluate the potential contribution of the use of three-dimensional (3D) ultrasound on repeatability, reproducibility and agreement of two-dimensional (2D) and 3D-derived measurements. MATERIALS AND METHODS Two observers (one senior and one junior) measured head circumference (HC), abdominal circumference (AC) and femur length (FL) in 33 fetuses (20 to 40 weeks of gestation). Each observer performed two series of 2D measurements and two series of 3D measurements (i.e., measurements derived from triplane volume processing). Measurements were converted into Z-scores according to gestational age. Variability between the different series of measurements was studied using Bland-Altmann plots and intra-class correlation coefficients (ICC). RESULTS Agreement with the 2D measurements of the senior observer was higher in 3D than in 2D for the junior observer (systematic differences of -0.4, -0.2 and -0.8 Z-score vs. -0.1, -0.1 and -0.6 for HC, AC and FL on 2D and 3D datasets, respectively). The use of 3D ultrasound improved junior observer repeatability (ICC=0.94, 0.88, 0.90 vs. 0.94, 0.94 and 0.96 for HC, AC and FL in 2D and 3D, respectively). The reproducibility was greater using the junior observer 3D datasets (ICC=0.75, 0.60 and 0.45 vs. 0.79, 0.89 and 0.63 for HC, AC and FL, respectively). CONCLUSION The use of 3D ultrasound improves the consistency of the measurements performed by a junior observer and increases the overall repeatability and reproducibility of measurements performed by observers with different levels of experience.
