Establishment-level safety analytics: a scoping review.

The use of data analytics has seen widespread application in fields such as medicine and supply chain management, but their application in occupational safety has only recently become more common. The purpose of this scoping review was to summarize studies that employed analytics within establishments to reveal insights about work-related injuries or fatalities. Over 300 articles were reviewed to survey the objectives, scope and methods used in this emerging field. We conclude that the promise of analytics for providing actionable insights to address occupational safety concerns is still in its infancy. Our review shows that most articles were focused on method development and validation, including studies that tested novel methods or compared the utility of multiple methods. Many of the studies cited various challenges in overcoming barriers caused by inadequate or inefficient technical infrastructures and unsupportive data cultures that threaten the accuracy and quality of insights revealed by the analytics.

Establishment-level occupational safety analytics: Challenges and opportunities.

In occupational safety and health, big data and analytics show promise for the prediction and prevention of workplace injuries. Advances in computing power and analytical methods have allowed companies to reveal insights from the "big" data that previously would have gone undetected. Despite the promise, occupational safety has lagged behind other industries, such as supply chain management and healthcare, in terms of exploiting the potential of analytics and much of the data collected by organizations goes unanalyzed. The purpose of the present paper is to argue for the broader application of establishment-level safety analytics. This is accomplished by defining the terms, describing previous research, outlining the necessary components required, and describing knowledge gaps and future directions. The knowledge gaps and future directions for research in establishment-level analytics are categorized into readiness for analytics, analytics methods, technology integration, data culture, and impact of analytics.

Intermittent Soft-Tissue Tumor Enlargement in Episodic Angioedema With Eosinophilia Syndrome.

ABSTRACT: Episodic hypereosinophilia and angioedema syndrome, also known as Gleich syndrome, is a rare entity characterized by recurrent episodes of eosinophilia, angioedema, urticaria, fever and weight gain with spontaneous resolution. It is classified as an idiopathic hypereosinophilic syndrome. Unlike other hypereosinophilic syndromes, it has a low risk for internal organ damage. We report the case of a 42-year-old male with a 28-year history of recurrent erythematous wheals and plaques and persistent hypereosinophilia. Physical examination revealed a well-defined subcutaneous nodule on his right lower limb that increased in size with each episode of angioedema. Histopathology evidenced a lipoma with intense eosinophil infiltration within the mature adipose tissue, while the specimen of the wheal revealed scarce perivascular and interstitial eosinophilic inflammatory infiltrate. Diagnosis of episodic angioedema with eosinophilia syndrome was made based on clinical and laboratory findings.

Offspring of mothers with bipolar disorder: a systematic review considering personality features.

OBJECTIVE: To examine personality/temperament features and mental health vulnerability in offspring of mothers with bipolar disorders (BD), including dimensions which may impact psychological characteristics or therapeutic measures. METHODS: A systematic review, following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, was conducted to search for original articles that investigated personality/temperament features of offspring of women with BD and emotional factors involved in the mother-child relationship. The electronic search was performed in the PubMed, Web of Science, and PsycINFO databases from February 2010 to February 2017. RESULTS: Ten quantitative studies were included in the analysis: seven from the United States, two from Brazil, and one from Canada. The narrative synthesis was categorized into three dimensions: 1) reliability of instruments for prediction of future psychopathology in offspring; 2) environmental risk factors for offspring; and 3) early interventions. The findings showed impairments in the offspring's lives, high rates of behavior and temperament problems, and psychiatric disorders. CONCLUSION: BD is a frequent psychiatric disorder, and the offspring of mothers with this condition are exposed to complex family relationships and psychosocial difficulties. If they are to ensure a good provision of mental health and psychosocial care to this unique population, early interventions must not neglect their contextual specificities. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD-42017039010.

Advancing safety analytics: A diagnostic framework for assessing system readiness within occupational safety and health.

Big data and analytics have shown promise in predicting safety incidents and identifying preventative measures directed towards specific risk variables. However, the safety industry is lagging in big data utilization due to various obstacles, which may include lack of data readiness (e.g., disparate databases, missing data, low validity) and personnel competencies. This paper provides a primer on the application of big data to safety. We then describe a safety analytics readiness assessment framework that highlights system requirements and the challenges that safety professionals may encounter in meeting these requirements. The proposed framework suggests that safety analytics readiness depends on (a) the quality of the data available, (b) organizational norms around data collection, scaling, and nomenclature, (c) foundational infrastructure, including technological platforms and skills required for data collection, storage, and analysis of health and safety metrics, and (d) measurement culture, or the emergent social patterns between employees, data acquisition, and analytic processes. A safety-analytics readiness assessment can assist organizations with understanding current capabilities so measurement systems can be matured to accommodate more advanced analytics for the ultimate purpose of improving decisions that mitigate injury and incidents.

Netherton Syndrome: Case Report and Review of the Literature.

Netherton syndrome (NS) is a rare genodermatosis with an autosomal recessive pattern of inheritance caused by pathogenic variants in the SPINK5 gene. It is characterized by a triad consisting of atopic diathesis, ichthyosis linearis circumflexa, and hair shaft abnormalities. Ichthyosis linearis circumflexa can be confused with atopic dermatitis leading to a delayed diagnosis. Furthermore, difficulty in making the differential diagnosis with other atopiform, erythrodermic, and ichthyosiform entities that exhibit hair shaft abnormalities represent a challenge. Trichoscopy is an accessible and noninvasive auxiliary diagnostic tool in these cases; the hair shaft abnormalities found in NS are bamboo, golf tee, and matchstick hairs. Identification of a pathogenic variant in the SPINK5 gene through genetic testing is necessary to confirm the diagnosis. Multiple treatment options are available including topical therapy with emollients, corticosteroids, calcineurin inhibitors, antiseptics, and narrowband UVB phototherapy. Systemic treatments comprehend intravenous immunoglobulins, and advances in the understanding of the pathophysiology of NS have led to more directed therapies with biologics such as infliximab, ixekizumab, secukinumab, ustekinumab, and dupilumab. Treatments currently under investigation include inhibitors of kallikrein 5, cathelicidins, drugs activating the transcription factor nuclear factor erythroid-derived 2-like 2, and gene therapy using autologous keratinocytes induced with a lentiviral vector encoding SPINK5.

Indurated Plaques on the Legs: Think Lymphoma.

Dear Editor, Primary cutaneous diffuse large B-cell lymphoma, leg-type (PCDLBCL-LT) is a rare and aggressive neoplasm. A timely diagnosis may prevent fatal outcomes; physicians should take this entity into consideration when assessing non-specific lesions on the lower limbs. We present a 69-year-old woman with a 1-month history of a firm plaque on her left leg. Physical examination revealed an asymptomatic, indurated, smooth, and erythematous plaque on the pretibial region of her left extremity (Figure 1, a). The rest of the physical examination was normal. Histological examination revealed cohesive sheets of a dense cell infiltrate in the dermis, composed of large round immunoblast-type cells with prominent nucleoli, and the presence of mitoses. Immunohistochemical stains were positive for CD20, Bcl2, and MUM1 (Figure 1, b-d). Additionally, c-MYC and Ki67 exhibited a 20% positivity; CD3 and CD10 were negative. The diagnosis of PCDLBCL-LT was established. Imaging and blood workup ruled out systemic involvement. Treatment with R-CHOP chemotherapy was initiated, with complete tumor regression by the third cycle. The patient completed 6 cycles and has remained disease-free after 18 months. Primary cutaneous B-cell lymphomas (CBCL) are lymphoproliferative disorders that appear on the skin without evidence of extracutaneous manifestations at the time of diagnosis (1). They represent 25 to 35% of all primary cutaneous lymphomas (2). In 2018, an updated version of the 2008 WHO-EORTC classification divided CBCLs into 5 subtypes: PCDLBCL-LT, primary cutaneous marginal zone B-cell lymphoma (PCMZL), primary cutaneous follicle center lymphoma (PCFCL), Epstein-Barr virus-positive mucocutaneous ulcer (EBVMCU), and intravascular large B-cell lymphoma (3). PCDLBCL-LT is the least common subtype, representing approximately 10% of all CBCLs and only 4% of all cutaneous lymphomas (2,3). Although the pathogenesis for most CBCLs is still unknown, positive serology for Lyme disease in a significant number of patients has been recognized as a probable etiologic association (4). PCDLBCL-LT is more frequent in women, and the mean age of presentation is 76 years. It usually presents as erythematous or bluish nodules, and up to 75% of the cases appears on one or both legs (1). Although infrequent, other locations have been reported, including the head, neck, trunk, and upper extremities (5). Workup should include a complete physical exam, skin biopsy, blood tests, and imaging (2,3). Histopathology shows a diffuse infiltrate in the dermis composed of large B-cells (centroblasts and/or immunoblasts) with extension to subcutaneous cellular tissue. These cells have round nuclei that are more than twice the size of normal lymphocytes, with prominent nucleoli. The immunophenotype of PCDLBCL-LT is CD20+, CD79a+, CD10-, and Bcl-6+/-, and strongly expresses Bcl-2, MUM1/IRF4, and FOX-P1 (1-3). Unlike the other indolent subtypes, PCDLBCL-LT is generally more aggressive with a poor prognosis. The 5-year disease survival rate is of approximately 50% (5). Management depends on the body surface area, location, and the patient's age and general health. To date, chemotherapy with R-CHOP remains the first line of therapy for PCDLBCL-LT, resulting in complete remission in up to 92% of cases (2). The prognostic characteristics of most PCDLBCL-LTs require timely and appropriate diagnosis and treatment.

The fatiguing effects of camera use in virtual meetings: A within-person field experiment.

The COVID-19 pandemic propelled many employees into remote work arrangements, and face-to-face meetings were quickly replaced with virtual meetings. This rapid uptick in the use of virtual meetings led to much popular press discussion of virtual meeting fatigue (i.e., "Zoom fatigue"), described as a feeling of being drained and lacking energy following a day of virtual meetings. In this study, we aimed to better understand how one salient feature of virtual meetings-the camera-impacts fatigue, which may affect outcomes during meetings (e.g., participant voice and engagement). We did so through the use of a 4-week within-person experience sampling field experiment where camera use was manipulated. Drawing from theory related to self-presentation, we propose and test a model where study condition (camera on versus off) was linked to daily feelings of fatigue; daily fatigue, in turn, was presumed to relate negatively to voice and engagement during virtual meetings. We further predict that gender and organizational tenure will moderate this relationship such that using a camera during virtual meetings will be more fatiguing for women and newer members of the organization. Results of 1,408 daily observations from 103 employees supported our proposed model, with supplemental analyses suggesting that fatigue affects same-day and next-day meeting performance. Given the anticipated prevalence of remote work even after the pandemic subsides, our study offers key insights for ongoing organizational best practices surrounding virtual meetings.

Cutaneous manifestations of Castleman disease.

BACKGROUND: Castleman disease (CD) is a lymphoproliferative B-cell disease that is diagnosed from lymphoid hyperplasia with vascular proliferation. Symptoms may include fever, night sweats, and weight loss. Cutaneous manifestations often may go unnoticed since little has been described in the literature regarding them. MATERIALS AND METHODS: A search of CD with cutaneous manifestations was performed in PUBMED, ProQuest, Ovid, Scopus, EMBASE, and Medline. All articles included patients over 18 years of age with a diagnosis of CD and cutaneous manifestations. RESULTS: A total of 68 articles were included. The most common cutaneous manifestations include paraneoplastic pemphigus and erythematous-brown plaques, papules, or nodules. Patients presenting with these manifestations should always have a thorough physical exam, and clinicians should try to identify any palpable lymph nodes. A complete workup to rule out other neoplasias needs to be performed as well. CONCLUSIONS: A better understanding of these skin manifestations of CD may help physicians promptly diagnose and reconsider the path of diagnostic tests to identify this entity.

Patients with Schizophrenia Undergoing Gastric Bypass Surgery: a Case Series Study.

PURPOSE: Obesity affects approximately 45-55% of persons with schizophrenia and is more difficult to manage in these individuals than in the general population, apart from being an additional factor for morbidity and premature mortality. Although bariatric surgery is considered the most effective long-term treatment for severe obesity, there are few reports on the outcomes of this procedure in persons with schizophrenia. This study aimed to evaluate weight loss and psychiatric symptoms in persons with obesity and schizophrenia after bariatric surgery. MATERIALS AND METHODS: Five persons with schizophrenia and moderate to severe obesity who underwent bariatric surgery were followed up for 2 years. Anthropometric data were collected, and psychiatric symptoms were evaluated using the Positive and Negative Syndrome Scale (PANSS), which assessed the pre- and postoperative occurrence and severity of symptoms of schizophrenia. RESULTS: The mean body mass index before surgery was 43.5 ± 5.2 kg/m2 and decreased to 28.1 ± 1.9 kg/m2 1 year postoperatively. The mean percentage of total postoperative weight loss was 30.7 ± 6.8% after 6 months, 34.7 ± 7.9% after 1 year, and 34.3 ± 5.5% after 2 years. Before surgery, all subjects were in remission based on the PANSS. Postoperative evaluations showed that the participants had no relapse of psychiatric symptoms (p > 0.05 for the three PANSS dimensions throughout the follow-up period). There were no considerable changes in their medication regimens. CONCLUSIONS: These findings suggest that bariatric surgery may be a viable treatment option for stable patients with schizophrenia if they have a preoperative assessment and close management and involvement by mental health professionals throughout the course of treatment.

Local secretion of stress hormones increases in alopecia areata lesions after treatment with UVA-1 phototherapy.

Alopecia areata (AA) is an autoimmune disease of the hair follicle. Keratinocytes of the hair follicle generate an immunosuppressive environment by the local secretion of hormones of the hypothalamic-pituitary-adrenal axis of the skin (skin HPA analog). Our objective was to measure the local production of corticotropin-releasing hormone (CRH), adrenocorticotropic hormone (ACTH), and α-melanocyte-stimulating hormone (α-MSH) in the scalp tissue of patients with AA before and after ultraviolet A1 (UVA-1) phototherapy to determine their role in the pathogenesis of AA and the effect of UVA-1 on the AA hormonal environment. This was a retrospective and descriptive study of skin samples from 22 patients with AA before and after UVA-1 treatment. We compared the changes in the local hormonal environment by measuring CRH, ACTH, type 2 melanocortin receptor (ACTH receptor) and α-MSH with immunohistochemical stains. The positivity of MSH was significantly higher (P = .037) in the post-treatment samples compared with the baseline value. ACTH was significantly higher in intensity (P = .032) in the post-treatment samples compared with the initial value. CRH was significantly higher in intensity (P = .013) in baseline samples compared with the final biopsies. The positivity of the ACTH receptor MC2R was not different between the two groups (P = .626). In AA, an interruption in the signalling of CRH could decrease the local concentration of ACTH and MSH, and consequently, the immunosuppressive effect of these hormones. This phenomenon is normalized in the skin treated with UVA-1. A defective signalling system in the cutaneous HPA axis may be involved in the pathogenesis of AA.

Advanced glycation endproducts produced by in vitro glycation of type I collagen modulate the functional and secretory behavior of dorsal root ganglion cells cultivated in two-dimensional system.

Advanced glycation end-products (AGEs) are proteins/lipids that are glycated upon sugar exposure and are often increased during inflammatory diseases such as osteoarthritis and neurodegenerative disorders. Here, we developed an extracellular matrix (ECM) using glycated type I collagen (ECM-GC), which produced similar levels of AGEs to those detected in the sera of arthritic mice. In order to determine whether AGEs were sufficient to stimulate sensory neurons, dorsal root ganglia (DRGs) cells were cultured on ECM-GC or ECM-NC-coated plates. ECM-GC or ECM-NC were favorable for DRG cells expansion. However, ECM-GC cultivated neurons displayed thinner F-actin filaments, rounded morphology, and reduced neuron interconnection compared to ECM-NC. In addition, ECM-GC did not affect RAGE expression levels in the neurons, although induced rapid p38, MAPK and ERK activation. Finally, ECM-GC stimulated the secretion of nitrite and TNF-α by DRG cells. Taken together, our in vitro glycated ECM model suitably mimics the in vivo microenvironment of inflammatory disorders and provides new insights into the role of ECM impairment as a nociceptive stimulus.
