Predictors of Making a Referral to Child Protective Services Prior to Expert Consultation.

OBJECTIVE: Suspicion for child abuse is influenced by implicit biases. Evaluation by a Child Abuse Pediatrician (CAP) may reduce avoidable child protective services (CPS) referrals. Our objective was to investigate the association of patient demographic, social and clinical characteristics with CPS referral before consultation by a CAP (preconsultation referral). METHODS: Children<5years-old undergoing in-person CAP consultation for suspected physical abuse from February 2021 through April 2022 were identified in CAPNET, a multicenter child abuse research network. Marginal standardization implemented with logistic regression analysis examined hospital-level variation and identified demographic, social, and clinical factors associated with preconsultation referral adjusting for CAP's final assessment of abuse likelihood. RESULTS: Among the 61% (1005/1657) of cases with preconsultation referral, the CAP consultant had low concern for abuse in 38% (384/1005). Preconsultation referrals ranged from 25% to 78% of cases across 10 hospitals (P < .001). In multivariable analyses, preconsultation referral was associated with public insurance, caregiver history of CPS involvement, history of intimate partner violence, higher CAP level of concern for abuse, hospital transfer, and near-fatality (all P < .05). The difference in preconsultation referral prevalence for children with public versus private insurance was significant for children with low CAP concern for abuse (52% vs 38%) but not those with higher concern for abuse (73% vs 73%), (P = .023 for interaction of insurance and abuse likelihood category). There were no differences in preconsultation referral based on race or ethnicity. CONCLUSIONS: Biases based on socioeconomic status and social factors may impact decisions to refer to CPS before CAP consultation.

Diagnosing muscle disease in a cohort of classic dermatomyositis patients seen at a rheumatologic dermatology outpatient clinic.

BACKGROUND: Existing criteria to improve the probability of capturing dermatomyositis (DM) include muscle biopsy but little is known about whether less invasive diagnostic procedures may be just as useful. OBJECTIVE: We aimed to determine whether skin biopsy, electromyography, or magnetic resonance imaging of the involved muscle could be done in lieu of muscle biopsy. METHODS: Two hundred and seventy-five patients were reviewed to investigate the presence of cutaneous and muscle disease, their timing in relation to diagnosis, and results of skin biopsies, muscle biopsies, magnetic resonance imaging, and electromyography. RESULTS: Of the cases with findings consistent with DM on muscle biopsy, 65% were in agreement with diagnostic features on electromyography or magnetic resonance imaging. Results of skin and muscle biopsies supported DM in 67% of patients who underwent both procedures. LIMITATIONS: A limited number of patients had muscle biopsies. CONCLUSION: In the presence of DM-specific skin findings, less invasive procedures may be sufficient to diagnose DM and guide its management.

Cutaneous lupus concerns from the patient perspective: a qualitative study.

OBJECTIVE: There is a need to identify concerns unique to patients with cutaneous lupus erythematosus (CLE), which may not be captured by current common-practice dermatological quality-of-life tools. This study formally characterises what bothers patients with CLE about their disease by conducting semistructured, qualitative interviews. METHODS: Sixteen patients with CLE were interviewed about how their cutaneous findings impact their daily life. Each interview was transcribed, coded and categorised for recurrent themes. Current CLE activity and damage were also assessed by the Cutaneous Lupus Activity and Severity Index tool. RESULTS: Responses were categorised into six themes, including Fear of Disease Progression, Unwanted Attention, Self-Consciousness, Physical Signs/Symptoms, Emotional Symptoms and Functional Decline. The most commonly reported themes were Self-Consciousness, mentioned by 13 of 16 (81.3%) patients, Physical Symptoms, mentioned by 12 of 16 (75%), and then Fear of Disease Progression, by 11 of 16 (68.8%). Frequently mentioned physical signs/symptoms included erythema, itch, dyspigmentation, scar and alopecia. The physical signs/symptoms were categorised as activity signs/symptoms, damage signs and other. For activity signs, erythema was mentioned most frequently (5 of 16), then scale (2 of 16). For activity symptoms, itch was mentioned most frequently (6 of 16), then pain (5 of 16). For damage signs, dyspigmentation was mentioned most frequently (4 of 16), followed by scarring (3 of 16). Patients less than 60 years old were more likely to report emotional symptoms than older patients (p<0.05), but there was no significant variation in frequency of reported themes between race, sex or subtype of CLE. CONCLUSIONS: These patient experiences and resultant themes elucidated by this study are worth noting in future standardised estimations of the quality of life of patients with CLE. Additionally, the concerns shown by these interviews are important topics for providers to discuss when evaluating patient disease progression.

Assessing the Correlation Between Disease Severity Indices and Quality of Life Measurement Tools in Pemphigus.

Pemphigus, an autoimmune blistering disease that affects the skin and mucous membranes, adversely impacts patients' quality of life (QOL). While there are various QOL measurement tools that can be used in this disease, few studies have assessed how a patient's change in disease severity can affect their QOL. This study aims to identify which disease severity index correlates best with the change in QOL. Fifty pemphigus patients completed QOL surveys with disease severity scored over two visits. QOL was assessed with the Autoimmune Bullous Disease Quality of Life (ABQOL), Dermatology Life Quality Index (DLQI), Skindex-29, and Short Form Survey 36 (SF-36). Disease severity was scored with the Pemphigus Disease Area Index (PDAI) and Autoimmune Bullous Skin Disorder Intensity Score (ABSIS). Correlations between the change in QOL scores and change in disease severity were analyzed using Spearman's coefficient (r). The change in PDAI showed a strong correlation (r = 0.60-0.79) with changes in the ABQOL, Skindex-29 symptoms (Skindex-S), and Skindex-29 functioning (Skindex-F) subscales for all patients (n = 50). For patients with mucosal disease (n = 24), the change in PDAI showed a strong correlation with changes in the ABQOL and Skindex-S subscale. For patients without mucosal disease, the change in PDAI showed a strong correlation with the Skindex-S. The change in ABSIS showed a strong correlation with Skindex-S for all patients and patients with no mucosal involvement, but showed no strong correlations for patients with mucosal involvement. The changes in PDAI always had a stronger correlation than the changes in ABSIS scores to changes in the ABQOL, DLQI, and Skindex-29 subscales, except where the PDAI and ABSIS scores were about the same for the Skindex-S subscale in patients with no mucosal involvement (r = 0.76 and r = 0.77, respectively). PDAI is superior to ABSIS in its correlation with validated QOL tools. The QOL tools that appear to be of most use in clinical trials and patient management are the Skindex-S and ABQOL.

SpCas9-expression by tumor cells can cause T cell-dependent tumor rejection in immunocompetent mice.

The CRISPR/Cas9 system has recently emerged as a highly efficient modality in genetic engineering and has been widely considered for various therapeutic applications. However, since the effector protein, SpCas9, has a bacterial origin, its immunogenicity must be explored in further depth. Here, we found that the intact immune system, in wild-type C57BL/6J and BALB/cL mice, stimulates specific immune response against SpCas9, resulting in the rejection of SpCas9-expressing tumors. However, these tumors effectively grew in syngeneic C57BL/6J immunodeficient, T cell-depleted and Cas9-KI mice. Therefore, these observations suggest that this tumor rejection phenotype is T cell-dependent. The immunological clearance of SpCas9-expressing tumors in the immunocompetent group illustrates the possibility of misinterpreting the impact of CRISPR/Cas9-mediated gene editing on in vivo tumor biology and survival. Thus, these findings have important implications for the use of this exciting approach in in vivo studies, as well as to manipulate cancer cell biology for therapeutic applications.

Functional genomics: paving the way for more successful cancer immunotherapy.

Immunotherapies have revolutionized cancer treatment. Immunotherapy is effective for the treatment of a wide range of cancer types and can mediate complete and durable tumor regression. Nonetheless, the field still faces many significant challenges, such as the need for personalized therapeutic strategies and better biomarkers, the difficulty of selecting the right combination therapy, and resistance to currently available immunotherapies. Both cancer and host immunity comprise significantly diverse and complex ecosystems, making immunogenomics an ideal field for functional genomics analysis. In this review, we describe the cancer-immunity cycle, how cancer cells manage to evade immune attack and the current hurdles in the path of cancer immunotherapy. Then, we discuss how functional genomics approaches can pave the way for more successful cancer immunotherapies.
