Pediatric Patient Surge: Evaluation of an Alternate Care Site Quality Improvement Initiative.

BACKGROUND: Pediatric Level I trauma centers often experience patient volume surges. The increase stresses the emergency department, and usual patient care areas become inadequate. The purpose of this quality improvement study is to describe the implementation and analysis of an alternate care site to facilitate patient flow during seasonal patient volume surges. METHODS: This initiative used a nonequivalent historical control group posttest-only design. An alternate care site was selected because of its size, temporary nature, low cost, and proximity to the emergency department. The alternate care site was activated between January and March 2019 using the following criteria: the total number of patients in waiting room 30 or more and wait times 2.5 hr or more. Outcome metrics include total census, length of stay-admissions, length of stay-discharges, left without being seen, hours per patient visit, patient satisfaction scores, and process metrics. Descriptive statistics and t tests were used to determine differences between groups. RESULTS: A total of 180 patients were analyzed with n = 90 from 2018 and n = 90 from 2019. The alternate care site was activated five times over one season. The alternate care site decreased median waiting times, length of stay-admissions, length of stay-discharges, and left without being seen as compared with the previous year. Hours per patient visit and patient satisfaction scores remained constant as compared with the previous year. CONCLUSIONS: The creation of an alternate care site within the emergency department allowed quick mobilization, response, and treatment of patients. The alternate care site decreased median length of stay for admissions, discharges, and who left without being seen while keeping hours per patient visit and patient satisfaction constant. Future studies should confirm findings by testing the alternate care site in other hospitals and settings and should consider formally evaluating staff satisfaction.

Communication of pain intensity and unpleasantness through magnitude ratings: Influence of scale type, but not gender of the participant.

BACKGROUND: A critical aspect for most human pain research is the ability of participants to communicate their first-person, experiential perspective to a third-person observer. This communication is frequently accomplished via pain ratings. The scale type can influence the communication of pain experiences and can contribute to gender differences in pain. This study examined the role of gender on pain ratings using noxious and innocuous stimuli across two types of rating scales. METHODS: Healthy participants (n = 46) underwent noxious heat, auditory and visual stimulation paradigms. Pain intensity and unpleasantness ratings were collected using the visual analogue scale (VAS) and numerical rating scale (NRS). To determine if one rating scale allows a better report of small differences between different stimulus intensities, the sensitivity to small differences was calculated. RESULTS: Significant effects for rating scale were found for all stimulus modalities (noxious heat, auditory and visual, p < 0.001) with higher intensity and unpleasantness ratings for the NRS compared to the VAS. Overall, no effects of gender or interactions with gender were found. No differences in rating scale and gender were detected for sensitivity to small differences between stimuli. CONCLUSIONS: These findings confirm differences in rating scale usage; however, the different usage might not contribute significantly to gender differences in pain. SIGNIFICANCE: There are differences in the usage of rating scales in which ratings for auditory, visual and noxious somatosensory stimuli are higher with NRS compared to VAS. Choosing a rating scale for research or clinical use should take this different item functioning into account.

Weak Relationships Between Psychological Factors and Experimental Pain Outcomes in Pain-Free Individuals: An Aggregate Analysis of 8 Studies.

Although psychological factors such as anxiety, depression, and pain catastrophizing are known to influence pain outcomes in chronic pain populations, there are mixed results regarding whether they influence experimental pain outcomes in pain-free individuals. The objectives of this study were to determine the associations between psychological factors and experimental pain outcomes in pain-free adolescents and adults. Relationships between anxiety, depression, and pain catastrophizing and experimental pain outcomes across 8 different studies (total N = 595) were examined in different populations of pain-free adult and adolescent participants. Analyses were conducted with and without controlling for sex, age, and race. Studies were analyzed separately and as part of an aggregate analysis. Individual study analyses resulted in 136 regression models. Of these, only 8 models revealed a significant association between psychological factors and pain outcomes. The significant results were small and likely due to Type 1 error. Controlling for demographic factors had minimal effect on the results. The aggregate analyses revealed weak relationships between anxiety and pressure pain threshold (Fisher's z = -.10 [-.19, -.01]), anxiety and cold pain intensity ratings (Fisher's z = .18 [.04, .32]), and pain catastrophizing and pressure pain threshold (Fisher's z = -.14 [-.26, -.02]). Sample size calculations based on the aggregate analyses indicated that several hundred participants would be required to detect true relationships between these psychological factors and pain measures. The overall negative findings suggest that in pain-free individuals, anxiety, depression, and pain catastrophizing are not meaningfully related to experimental pain outcomes. PERSPECTIVE: Psychological variables have been shown to predict pain outcomes in chronic pain populations but these relationships may not generalize to pain-free populations. An analysis of 595 pain-free individuals across 8 studies in our lab revealed that anxiety, depression, and pain catastrophizing were not meaningfully related to experimental pain outcomes.

Observational analysis of clinical and pathological characteristics and their prognostic impact in Mexican patients with breast cancer: A multi-center study.

Breast cancer is the most incidental and deadly neoplasm worldwide; in Mexico, very few epidemiologic reports have analyzed the pathological features and its impact on their clinical outcome. Here, we studied the relation between pathological features and the clinical presentation at diagnosis and their impact on the overall and progression-free survival of patients with breast cancer. For this purpose, we collected 199 clinical records of female patients, aged at least 18 years old (y/o), with breast cancer diagnosis confirmed by biopsy. We excluded patients with incomplete or conflicting clinical records. Afterward, we performed an analysis of overall and progression-free survival and associated risks. Our results showed an average age at diagnosis of 52 y/o (24-85), the most common features were: upper outer quadrant tumor (32%), invasive ductal carcinoma (76.8%), moderately differentiated (44.3%), early clinical stages (40.8%), asymptomatic patients (47.8%), luminal A subtype (47.8%). Median overall survival was not reached, but median progression-free survival was 32.2 months (29.75-34.64, CI 95%) associated risk were: clinical stage (p < 0.0001) symptomatic presentation (p = 0.009) and histologic grade (p = 0.02). Therefore, we concluded that symptom presence at diagnosis impacts progression-free survival, and palpable symptoms are related to an increased risk for mortality.

The Effects of a 2-hour Surfing Session on the Hydration Status of Male Recreational Surfers.

Surfing is a popular sport globally which is performed in varied environmental conditions. With limited research in the field exploring hydration, monitoring the effect of surfing on subject hydration is warranted. The purpose of this study was to determine the relationship between surfing intensity and hydration status. A total of ten recreational male surfers were recruited for this study where hydration status was assessed pre-and post-surf session by measures of body mass (BM) and urine specific gravity (USG). Intensity of the surf session was quantified by Global Positioning Systems and Heart Rate monitoring. Subjects surfed for two hours and covered an average distance of 4974.18 ± 542.62 m, with an average speed of 2.48 ± 0.27 km/h and peak speed of 31.86 ± 3.51 km/h. A statistically significant decrease in absolute and relative BM was observed (0.70 ± 0.4 kg, p < 0.05 & 0.86 ± 0.54%, p < 0.001, respectively). No statistically significant correlation was found between variables (total distance paddled and relative BM, r = 0.432, p = 0.245; average HR and relative BM change, r = -.246, p = 0.595). Total distance paddled combined with average HR significantly predicted relative body mass change (F(2,3) = 29.362, p = 0.011, adjusted R 2 = 95.1%). The results demonstrate that a 2-hour recreational surfing session, in temperate environmental conditions, without neoprene garments resulted in minimal BM changes and no changes in USG. Surfers who paddle a greater distance at a higher average HR sustained greater BM changes.

Increased pain sensitivity but normal pain modulation in adolescents with migraine.

Inhibitory pain modulation has been reported to be deficient in adults across different types of chronic pain, including migraine. To determine whether a similar phenomenon occurs in youth, we performed a quantitative sensory testing investigation in adolescents with migraine (N = 19). These patients were compared to healthy adolescents with (Fam-His; N = 20) or without (Healthy; N = 29) a family history of migraine (eg, first-degree relative with migraine). Subjects were first familiarized with the stimuli and visual analogue rating scales using graded noxious stimuli (0°C, 43-49°C range). These data were used to explore potential pain sensitivity differences between the groups. Pain inhibition was assessed by conditioned pain modulation (CPM), which used both suprathreshold heat pain (heat CPM) and pressure pain thresholds (pressure CPM) as the test stimuli before and during cold-water immersion (8°C). In response to the graded heat stimuli, Fam-His participants reported higher pain intensity ratings compared with patients with migraine, who in turn reported higher pain intensity ratings than the healthy controls (F = 3.6, [df = 2, 459], P = 0.027). For heat and pressure CPM, there was no significant group difference in the magnitude of CPM responses. Thus, adolescents with migraine and healthy adolescents have similar inhibitory pain modulation capability, despite having marked differences in pain sensitivity. Although Fam-His participants are asymptomatic, they demonstrate alterations in pain processing, which may serve as markers for prediction of migraine development.

Functional and Aesthetic Thorax Reconstruction after Desmoid Tumor Resection.

This study describes a case report of a 31-year-old patient who presented with a left thoracic tumor on costal cartilages 5 and 6 that was diagnosed as a desmoid tumor 3 years after receiving retropectoral breast implants for cosmetic reasons. The integral reconstruction of the thoracic wall, functional and aesthetic, was planned for a single surgical period. The defect secondary to the tumor resection, which left the pericardium and lung exposed, was closed using the pectoral muscle as a "pre-expanded" flap by the breast implant, and the breast aesthetic was treated bilaterally with new implants in the retromammary position. After 12 months, the patient remained free from tumor recurrence and had a satisfactory aesthetic result.

Pulmonary artery sarcoma with angiosarcoma phenotype mimicking pleomorphic malignant fibrous histiocytoma: a case report.

Primary sarcomas of the major blood vessels can be classified based on location in relationship to the wall or by histologic type. Angiosarcomas are malignant neoplasms that arise from the endothelial lining of the blood vessels; those arising in the intimal compartment of pulmonary artery are rare. We report a case of pulmonary artery angiosarcoma in a 36-year old female with pulmonary masses. The patient had no other primary malignant neoplasm, thus excluding a metastatic lesion. Gross examination revealed a thickened right pulmonary artery and a necrotic and hemorrhagic tumor, filling and occluding the vascular lumen. The mass extended distally, within the pulmonary vasculature of the right lung. Microscopically, an intravascular undifferentiated tumor was identified. The tumor cells showed expression for vascular markers VEGFR, VEGFR3, PDGFRa, FGF, Ulex europaeus, FVIII, FLI-1, CD31 and CD34; p53 was overexpressed and Ki67 proliferative rate was increased. Intravascular angiosarcomas are aggressive neoplasms, often associated with poor outcome.
