Non-Invasive markers of inflammation and protein loss augment diagnosis of celiac disease.

Background: Circulating tissue transglutaminase IgA (TTG IgA) concentrations are sensitive and specific indicators of celiac disease, but discrepancies between serologic and histologic findings still occur. We hypothesized that fecal markers of inflammation and protein loss would be greater in patients with untreated celiac disease than in healthy controls. Our study aims to evaluate multiple fecal and plasma markers in celiac disease and correlate these findings with serologic and histologic findings as non-invasive means of evaluating disease activity. Methods: Participants with positive celiac serologies and controls with negative celiac serologies were enrolled at the time of upper endoscopy. Blood, stool and duodenal biopsies were collected. Concentrations of fecal lipocalin-2, calprotectin and alpha-1-antitrypsin and plasma lipcalin-2 were determined. Biopsies underwent modified Marsh scoring. Significance was tested between cases and controls, modified Marsh score and TTG IgA concentration. Results: Lipocalin-2 was significantly elevated in the stool ( p =0.007) but not the plasma of participants with positive celiac serologies compared to controls. There was no significant difference in fecal calprotectin or alpha-1 antitrypsin between participants with positive celiac serologies and controls. Fecal alpha-1 antitrypsin >100mg/dL was specific, but not sensitive for biopsy proven celiac disease. Conclusions: Lipocalin-2 is elevated in the stool but not the plasma of patients with celiac disease suggesting a role in the local inflammatory response. Calprotectin was not a useful marker in the diagnosis of celiac disease and did not correlate with degree of histologic changes on biopsy. While random fecal alpha-1 antitrypsin was not significantly elevated in cases compared to controls, an elevation of greater than 100mg/dL was 90% specific for biopsy proven celiac disease.

Purtscher-like retinopathy in a patient with COVID-19-associated coagulopathy / Retinopatia tipo Purtscher em paciente com coagulopatia associada ao COVID-19

ABSTRACT The most frequently reported ophthalmic manifestation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is conjunctivitis. We have described a case of Purtscher-like retinopathy in a patient with severe coronavirus disease 2019 (COVID-19)-associated coagulopathy. A young woman with multiple comorbidities was admitted for COVID-19-related acute respiratory distress syndrome. Her course was complicated by fungemia. Ophthalmic examination revealed bilateral posterior pole, intraretinal lesions and fluconazole was added for presumed fungal retinitis. At 1-week follow-up, widespread peripapillary cotton-wool spots and hemorrhages suggestive of Purtscher-like retinopathy were observed. The levels of D-dimers, fibrinogen, and C-reactive protein were markedly elevated prior to our consultation, indicating preceding prothrombotic and pro-inflammatory states. Subsequent venous duplex revealed deep venous thrombosis in the right subclavian and internal jugular veins. Von Willebrand factor indices were markedly elevated, suggesting severe COVID-19-associated coagulopathy. Purtscher-like retinopathy, a rare occlusive microangiopathy has been described in various pro-inflammatory and prothrombotic conditions. To the best of our knowledge, this is the first report of Purtscher-like retinopathy in COVID-19-associated coagulopathy.

Measurement of Pectoralis Minor Muscle Length in Women Diagnosed With Breast Cancer: Reliability, Validity, and Clinical Application.

BACKGROUND: Decreased pectoralis minor muscle length is common after primary breast cancer treatment and can result in an abnormal position of the scapula. This position can contribute to shoulder pain and pathomechanics and can lead to problems such as impingement syndrome, rotator cuff tears, and frozen shoulder. Currently, there are limited reliable methods for measuring pectoralis minor length. OBJECTIVE: The objective of this study was to examine the reliability and validity of measuring pectoralis minor length in women diagnosed with breast cancer. DESIGN: This was a cross-sectional reliability and validity study. METHODS: Bilateral pectoralis minor length (in centimeters) was assessed using a palpation meter in women (N = 29) diagnosed with breast cancer by 2 licensed physical therapists who were masked to the measures. Bilateral pectoralis minor length was also measured using a motion capture system to assess validity. RESULTS: Intratester reliability (intraclass correlation coefficient, ICC [3,k] = 0.971; 95% confidence interval [CI] = 0.939-0.986; standard error of measurement [SEM] = 0.16 cm) and intertester reliability (ICC[3,k] = 0.915; 95% CI = 0.81-0.962; SEM = 0.31 cm) were excellent for the palpation meter on the affected side and the unaffected side (intratester reliability: ICC[3,k] = 0.951; 95% CI = 0.897-0.977; SEM = 0.19 cm; intertester reliability: ICC[3,k] = 0.945; 95% CI = 0.877-0.975; SEM = 0.22 cm). Significant correlations were found between the motion capture system and the palpation meter on the affected side (r = 0.87) and the unaffected side (r = 0.81). Bland-Altman plots between the palpation meter and the motion capture system demonstrated that all the measures fell within the limits of agreement. LIMITATIONS: This study encountered possible errors with the accuracy of the motion capture system tracking because of the proximity of the markers and inherent volumetric restrictions. CONCLUSIONS: The palpation meter is a reliable, valid, easily administered, and cost-effective tool for assessing pectoralis minor length in women with breast cancer.

Thoracoabdominal Asynchrony Is Not Associated with Oxyhemoglobin Saturation in Recovering Premature Infants.

BACKGROUND: Recovering premature infants are at risk for hypoxemia and lack of synchrony between their rib cage and abdomen due to airflow obstruction and poor respiratory compliance. Thoracoabdominal asynchrony (TAA) is a useful marker of resistive and elastic lung properties. Whether TAA predicts oxygenation is unknown. OBJECTIVES: We investigated oxyhemoglobin saturation (SpO2%) and TAA (phase angle, φ) in preterm infants with/without high-humidity nasal cannula (HHNC). METHODS: A cross-sectional observational study was conducted in 92 infants at 32 weeks' postmenstrual age. We measured SpO2% with pulse oximetry and TAA with φ via respiratory inductance plethysmography in infants (mean gestational age: 26.4 + 1.3 weeks) who required room air (n = 18) or HHNC with/without supplemental oxygen (1-5 liters per minute, FiO2 0.21-0.33, n = 74). We calculated median SpO2% from 24.7 + 10.0 min of quiet sleep and median φ from up to 60 breaths. RESULTS: Infants breathing room air alone had marked TAA (φ = 83.6 + 32.9°, range: 10.9-148.5) as did those receiving varying degrees of ventilatory and oxygen support via HHNC (range of group means, φ = 47.0-90.0°). Infants breathing room air had statically greater median SpO2% than those receiving support (96.3 + 0.6% vs. 91.3 + 0.6%; ANOVA p = 0.001). SpO2% was not associated with TAA in either group (r2 = 0.09). CONCLUSION: Recovering premature infants exhibited TAA regardless of need for ventilatory support and supplemental oxygen. TAA was not associated with SpO2% in either group. Maintenance of SpO2% does not require correction of TAA.

Promoting Community Health and Eliminating Health Disparities Through Community-Based Participatory Research.

In physical therapy, there is increasing focus on the need at the community level to promote health, eliminate disparities in health status, and ameliorate risk factors among underserved minorities. Community-based participatory research (CBPR) is the most promising paradigm for pursuing these goals. Community-based participatory research stresses equitable partnering of the community and investigators in light of local social, structural, and cultural elements. Throughout the research process, the CBPR model emphasizes coalition and team building that joins partners with diverse skills/expertise, knowledge, and sensitivities. This article presents core concepts and principles of CBPR and the rationale for its application in the management of health issues at the community level. Community-based participatory research is now commonly used to address public health issues. A literature review identified limited reports of its use in physical therapy research and services. A published study is used to illustrate features of CBPR for physical therapy. The purpose of this article is to promote an understanding of how physical therapists could use CBPR as a promising way to advance the profession's goals of community health and elimination of health care disparities, and social responsibility. Funding opportunities for the support of CBPR are noted.

Ventilatory control and supplemental oxygen in premature infants with apparent chronic lung disease.

OBJECTIVES: Our goal was to evaluate changes in respiratory pattern among premature infants born at <29 weeks gestation who underwent a physiological challenge at 36 weeks postmenstrual age with systematic reductions in supplemental oxygen and inspired airflow. STUDY DESIGN: Subjects were all infants enrolled in the Prematurity and Respiratory Outcomes Project at St. Louis Children's Hospital and eligible for a physiological challenge protocol because they were receiving supplemental oxygen or augmented airflow alone as part of their routine care. Continuous recording of rib cage and abdominal excursion and haemoglobin oxygen saturation (SpO2%) were made in the newborn intensive care unit. RESULTS: 37 of 49 infants (75.5%) failed the challenge, with severe or sustained falls in SpO2%. Also, 16 of 37 infants (43.2%) who failed had marked increases in the amount of periodic breathing at the time of challenge failure. CONCLUSIONS: An unstable respiratory pattern is unmasked with a decrease in inspired oxygen or airflow support in many premature infants. Although infants with significant chronic lung disease may also be predisposed to more periodic breathing, these data suggest that the classification of chronic lung disease of prematurity based solely on clinical requirements for supplemental oxygen or airflow do not account for multiple mechanisms that are likely contributing to the need for respiratory support.

Empirically supported psychological treatments: the challenge of evaluating clinical innovations.

Clear and transparent standards are required to establish whether a therapeutic method is "evidence based." Even when research demonstrates a method to be efficacious, it may not become available to patients who could benefit from it, a phenomenon known as the "translational gap." Only 30% of therapies cross the gap, and the lag between empirical validation and clinical implementation averages 17 years. To address these problems, Division 12 of the American Psychological Association published a set of standards for "empirically supported treatments" in the mid-1990s that allows the assessment of clinical modalities. This article reviews these criteria, identifies their strengths, and discusses their impact on the translational gap, using the development of a clinical innovation called Emotional Freedom Techniques (EFT) as a case study. Twelve specific recommendations for updates of the Division 12 criteria are made based on lessons garnered from the adoption of EFT within the clinical community. These recommendations would shorten the cycle from the research setting to clinical practice, increase transparency, incorporate recent scientific advances, and enhance the capacity for succinct comparisons among treatments.

A model for large-scale, interprofessional, compulsory cross-cultural education with an indigenous focus.

Cultural competency training for health professionals is now a recognised strategy to address health disparities between minority and white populations in Western nations. In Australia, urgent action is required to "Close the Gap" between the health outcomes of Indigenous Australians and the dominant European population, and significantly, cultural competency development for health professionals has been identified as an important element to providing culturally safe care. This paper describes a compulsory interprofessional first-year unit in a large health sciences faculty in Australia, which aims to begin students on their journey to becoming culturally competent health professionals. Reporting primarily on qualitative student feedback from the unit's first year of implementation as well as the structure, learning objects, assessment, and approach to coordinating the unit, this paper provides a model for implementing quality wide-scale, interprofessional cultural competence education within a postcolonial context. Critical factors for the unit's implementation and ongoing success are also discussed.

Functional outcomes of adult patients with West Nile virus admitted to a rehabilitation hospital.

BACKGROUND AND PURPOSE: The clinical manifestation of West Nile Virus (WNV) varies in individuals from mild flu-like symptoms to acute flaccid paralysis. Advanced age is the most significant risk factor for developing severe neurological disease and for death. The broad range of neurologic symptoms associated with WNV infection leads to varied body structure and function limitations and participation restrictions that may require rehabilitation. The purpose of this study is to describe the functional impairments upon admission and the functional outcomes at discharge of 48 adult patients admitted with WNV to a rehabilitation facility in the Midwest from 2002 to 2009. METHODS: A retrospective chart review was completed on 48 patients (29 male, 19 female) with mean age 67.8 (SD = 16.6, range = 24-91) years and median age 72.5 years, admitted to inpatient rehabilitation with a diagnosis of WNV after January 1, 2002, and discharged prior to December 31, 2009. General information (sex, age, social history, employment, and living environment), past medical history, and information specific to the current hospitalization (medical conditions, functional status and activity level on admission and discharge as measured by the Functional Independence Measure [FIM], lengths of stay [LOSs] in the acute care and rehabilitation hospital, physical therapy care, discharge destination, and follow-up care provisions) were gathered. The standardized response mean (SRM) was calculated for total, motor, and cognitive FIM scores to provide insight into the effect size and the responsiveness of the FIM for the patients with WNV in this study. RESULTS: All patients were admitted to the rehabilitation hospital from acute care hospitals following LOSs ranging from 1 to 62 days. The rehabilitation hospital LOS ranged from 2 to 304 days. These patients had significant comorbidities including hypertension (43.75%), diabetes mellitus (41.67%), acute respiratory failure (37.5%), ventilator dependency/tracheostomy (33.33%), and pneumonia (29.17%). Their admission FIM scores ranged from 13 to 116 (mean = 45.8 ± 28.2) and discharge FIM scores ranged from 18 to 121 (mean = 75.1 ± 34.2). The change in FIM during inpatient rehabilitation was statistically significant (P < .001). The calculated SRM for the total (1.06) and motor (1.12) FIM indicate a large effect size, whereas the SRM for the cognitive FIM (0.79) indicates a moderate effect. The majority of patients were discharged home or to a nursing facility (46%), skilled or extended care (38%) with a need for continued rehabilitation services. DISCUSSION AND CONCLUSIONS: The manifestation of the WNV and functional outcomes after comprehensive rehabilitation vary from patient to patient. Higher numbers of comorbid conditions lead to more complex presentation and challenge rehabilitation professionals to design individualized plans of care to enable these patients to achieve the highest functional outcomes. Most patients require follow-up physical therapy care after discharge from rehabilitation.

Functional outcomes of patients with sternectomy after cardiothoracic surgery: a case series.

PURPOSE: One potential complication after cardiothoracic surgery involves mediastinitis, which may lead to a sternectomy. A sternectomy involves partial or total debridement of the sternum to remove infected bone. Little evidence regarding functional outcomes following sternectomy exists in literature. The purpose of this case series is to report the demographics of 6 patients admitted to a long term acute care hospital (LTACH) treated for sternectomy after open heart surgery, along with presenting length of stay (LOS) data, analyzing functional outcomes, and describing the physical therapy (PT) interventions used with these patients to obtain the reported functional outcomes. METHODS: Medical charts were reviewed retrospectively. Information in four main areas were extrapolated from the chart and further analyzed: patient demographics, length of hospital stay (acute care and LTACH), admission and discharge FIM scores, and information about the PT interventions (both numerical and descriptive). RESULTS: Patients included 5 males and 1 female with an age range of 65-78 years old (mean 70 years old, SD 4.8 years). Patients had a total mean acute care LOS of 26.33 (12.26) days and total mean LTACH LOS of 27.67 (11.74) days. Median total FIM score at admission was 80.00 [range 58.00-94.00], while the median total FIM score at discharge increased significantly to 106.50 [range 86.00-116.00] (p = 0.031). Total mean FIM score change during LTACH stay (efficiency) was 25.17 (3.25), and FIM score change per day (efficacy) was 1.23 (0.46). Median motor score had a significant increase from admission to discharge (p = 0.031). Median cognitive score did not significantly change from admission to discharge (p = 0.125). PT interventions used with this patient population were presented and described, with a mean number of PT sessions in LTACH of 27.33 (15.38) (range = 10-46). CONCLUSION: Although patients required an increased acute care LOS and an additional stay on LTACH, all 6 patients were discharged home following a course of multi-disciplinary inpatient rehabilitation on a LTACH unit. Patients are able to make significant functional gains during rehabilitation following sternectomy, as evidenced by increases in FIM score.

S-adenosylmethionine concentrations in diagnosis of Pneumocystis carinii pneumonia.

Pneumocystis carinii is unable to synthesise S-adenosylmethionine and thus scavenges this intermediate. We aimed to test whether measurement of concentrations of this metabolic intermediate in plasma could provide a new method for rapid diagnosis of Pneumocystis carinii pneumonia (PCP). We measured S-adenosylmethionine plasma concentrations in 12 healthy controls, 16 patients with confirmed or suspected PCP, and 36 patients with other infections. Median concentration in healthy controls was 106 nmol/L (range 86-128), but the protein was undetectable in eight patients with histologically proven and seven with suspected PCP, and was 8 nmol/L in another confirmed case (p<0.0001). In 36 patients with other infections, S-adenosylmethionine concentrations were much the same as in controls: 18 had bacterial pneumonia, two tuberculosis, five cryptococcal meningitis, three had other infections, and eight had asymptomatic HIV-1 infection. After treatment for PCP, S-adenosylmethionine concentrations rose rapidly in all but one patient who died of the disease. Measurement of plasma S-adenosylmethionine concentrations could prove useful for diagnosis of PCP and assessment of patients' response to treatment.
