Using longitudinal archival Child Welfare System (CWS) data, this study describes child health and wellbeing at their initial entrance into the CWS and subsequent returns. Associations between child ...wellbeing, health, placement stability, and frequency of returning to the system were also investigated. Results indicated most children were healthy and developmentally on target. In addition, emotional distress, behavioral concerns, and number of placements in the CWS were significantly correlated with placement stability. Future work should utilize the use of developmental assessments to systematically and reliably document the concerns for children in the system, and investigate factors contributing to stable placements.
The hygiene hypothesis claims that the lack of exposure to microorganisms in developed countries correlates with a rise in the incidence of autoimmune diseases. It was also found that helminths are ...able to modulate the immune response in hosts in order to survive. Consequently, several successful trials using helminths as a treatment for autoimmune patients have been reported. The helminth derivative, phosphorylcholine (PC), was discovered as an immunomodulatory molecule. We have recently shown in a murine model that when a conjugate of tuftsin and PC, termed TPC, is prophylactically administered before the onset of glomerulonephritis, it attenuates the development of systemic lupus erythematosus (SLE). The current study aimed to examine the TPC effect on the gut microbiome in a mouse model of lupus. TPC treatment altered the gut composition in the mice with active lupus, in correlation with a significant decrease in glomerulonephritis, followed by an increased level of anti-inflammatory interleukin 10 (IL-10), decreased levels of proinflammatory mediators, and expansion of the T regulatory cell population. Importantly, we found that TPC treatment altered the mouse gut microbiome composition, in correlation with a significant decrease in protein secretion and improved disease parameters. The major effects of TPC treatment on the gut microbiome included decreased abundances of
and increased abundance of several genera, including

. Overall, our results associate microbial changes with the immunomodulation of glomerulonephritis in mice with lupus.
Recently, several papers referred to the association of different bacteria with lupus in mice and humans. This is the first report to demonstrate the effect of a compound derived from helminths on the induction of remission in mice with lupus and its association with a bacterial change. We show that several genera, including
, are associated with clinical and serological parameters of lupus, while other genera, including butyrate-producing bacteria, are associated with amelioration of disease following tuftsin and phosphorylcholine treatment.
Acute auricular hematoma can be caused by direct blunt trauma or other injury to the external ear. It is typically seen in those who practice full contact sports such as boxing, wrestling, and rugby. ..."Cauliflower ear" deformity, fibrocartilage formation during scarring, is a common complication of auricular hematomas. Therefore, acute drainage of the hematoma and postprocedural techniques for preventing recurrence are necessary for preventing the deformity. There are many techniques although no superior method of treatment has been found. In this case report, we describe a novel method using needle aspiration followed by the application of a magnet and an adapted disc to the affected area of the auricular. This minimally invasive, simple, and accessible method could potentially facilitate the treatment of cauliflower ear among full contact sports athletes.
ABSTRACT
Use of complementary and alternative medicine for wound healing is influencing mainstream medical practice. This systematic review evaluates the role of Calendula officinalis flower extract ...as monotherapy compared to control for wound healing in vivo. Searches were conducted in PubMed, EMBASE, Cochrane Central Register of Controlled Trials, CINAHL, and Scopus (up to April 2018) with 14 studies meeting the inclusion criteria, comprising 7 animal experiments and 7 clinical trials. Findings from the review on acute wound healing showed faster resolution of the inflammation phase with increased production of granulation tissue in the test groups treated with extract. These findings were consistent in five animal studies and one randomized clinical trial. Chronic wound healing studies were varied. Two clinical control studies on venous ulcers demonstrated decreased ulcer surface area compared to controls. Another randomized clinical trial demonstrated no improvement for the calendula group in diabetic leg ulcer healing. Burn healing similarly showed mixed results. Two animal studies demonstrated a prophylactic effect for the administration of calendula extract prior to burn injury. A randomized clinical trial of patients suffering from partial to full thickness burns demonstrated no benefit for topical application of calendula extract compared to controls. Two randomized clinical trials assessed the potential for extract to prevent acute post radiation dermatitis, with one study showing improvements compared to trolamine, while the other found no improvement compared to aqua gel cream. Animal studies provide moderate evidence for improved recovery from the inflammation phase and increased production of granulation tissue in calendula extract treatment groups. This review identified some evidence for the beneficial effects of C. officinalis extract for wound healing, consistent with its role in traditional medicine. There is a need for larger, well‐designed randomized control trials to assess the effect of calendula on wound healing including complications.
The p53 protein is the most studied tumor suppressor and the p53 pathway has been shown to mediate cellular stress responses that are disrupted when cancer develops. After DNA damage, p53 is ...activated as transcription factor to directly induce the expression of target genes involved in cell-cycle arrest, DNA repair, senescence and, importantly, apoptosis. Post-translational modifications of p53 are essential for the activation of p53 and for selection of target genes. The tumor suppressor homeodomain-interacting protein kinase-2 (HIPK2) is a crucial regulator of p53 apoptotic function by phosphorylating its N-terminal serine 46 (Ser46) and facilitating Lys382 acetylation at the C-terminus. HIPK2 is activated by numerous genotoxic agents and can be deregulated in tumors by several conditions including hypoxia. Recent findings suggest that HIPK2 active/inactive protein can affect p53 function in multiple and unexpected ways. This makes p53 as well as HIPK2 interesting targets for cancer therapy. Hence, understanding the role of HIPK2 as p53 activator may provide important insights in the process of tumor progression, and may also serve as the crucial point in the diagnostic and therapeutical aspects of cancer.
Reprogramming of differentiated cells into induced pluripotent cells (iPS) was accomplished in 2006 by expressing four, or less, embryonic stem cell (ESC)-specific transcription factors. Due to the ...possible danger of DNA damage and the potential tumorigenicity associated with such DNA damage, attempts were made to minimize DNA integration by the vectors involved in this process without complete success. Here we present a method of using RNA transfection as a tool for reprogramming human fibroblasts to iPS. We used RNA synthesized in vitro from cDNA of the same reprogramming four transcription factors. After transfection of the RNA, we show intracellular expression and nuclear localization of the respective proteins in at least 70% of the cells. We used five consecutive transfections to support continuous protein expression resulting in the formation of iPS colonies that express alkaline phosphatase and several ESC markers and that can be expanded. This method completely avoids DNA integration and may be developed to replace the use of DNA vectors in the formation of iPS.
In growing children, temporomandibular joint (TMJ) ankylosis and septic arthritis are uncommon. Retrognathia and micrognathia affect airway patency and can cause obstructive sleep apnea (OSA). No ...unified diagnostic criteria have been established for the management of this pathology. We describe the first case of treatment for pediatric TMJ ankylosis and severe OSA due to neonatal group B streptococcal septic TMJ arthritis. Untreated pathological changes in the TMJ will eventually lead to ankylosis. Among children, this will include facial growth disturbances leading to mandibular retrognathia, reduction in the oropharyngeal spaces, and OSA. Our patient had severe OSA with an apnea-hypopnea index of 24.9 events/h and oxygen saturation nadir of 73% as measured by polysomnography. She was treated successfully according to Andrade protocol. This is the first report of pediatric OSA due to TMJ ankylosis following neonatal group B streptococcal septic arthritis.

Dental origin constitutes most chronic unilateral maxillary sinusitis (CMS) and is referred to as dental chronic maxillary sinusitis (DCMS). Recently, dental implants and related surgical procedures ...have become more prevalent. We present an evaluation of the simultaneous treatment of DCMS.
A retrospective review of records from 395 patients with CMS treated at our medical center from 2015 to 2020 found 65 patients diagnosed with DCMS. Statistical analyses were performed using the records data.
Four patients were excluded. The final study population included 35 males and 26 females with a mean age of 55. 29 % were post-dental implant placement or related pre-prosthetic procedures. Presenting symptoms included middle meatus edema (72 %), pus in the middle meatus (70 %), and nasal secretion (39 %). Clinical findings included septal deviation (39 %), among them 87 % deviated toward the diseased sinus, OAF (49 %), and nasal polyposis (16 %). In 32 patients, the OAF was closed in one layer using a local mucoperiosteal flap. In 29 patients, the closure was done in two layers, including a buccal fat pad (BFP) regional flap. One patient had a reopened OAF, and five patients required revision surgery. 92 % of patients in this study had complete clinical and radiological resolution of the DCMS.
Relevance of nasal septal deviation in association with DCMS is present. There is no distinct difference in the manner of OAF closure if it is done in a simultaneous procedure. One stage combined multidisciplinary surgical procedure is sufficient to treat DCMS.
•The incidence of DCMS with or without OAF is increasing.•Complications, such as implant displacement into the maxillary sinus, are underreported in the literature.•There is a clear association between nasal septal deviation and DCMS.•We show that single-stage combined FESS and per-oral surgical treatment of DCMS with OAF is a feasible, minimally invasive procedure.•There is no significant difference in success rates between different methods of OAF closure.
Motivation: Predicting the metastatic potential of primary malignant tissues has direct bearing on the choice of therapy. Several microarray studies yielded gene sets whose expression profiles ...successfully predicted survival. Nevertheless, the overlap between these gene sets is almost zero. Such small overlaps were observed also in other complex diseases, and the variables that could account for the differences had evoked a wide interest. One of the main open questions in this context is whether the disparity can be attributed only to trivial reasons such as different technologies, different patients and different types of analyses. Results: To answer this question, we concentrated on a single breast cancer dataset, and analyzed it by a single method, the one which was used by van't Veer et al. to produce a set of outcome-predictive genes. We showed that, in fact, the resulting set of genes is not unique; it is strongly influenced by the subset of patients used for gene selection. Many equally predictive lists could have been produced from the same analysis. Three main properties of the data explain this sensitivity: (1) many genes are correlated with survival; (2) the differences between these correlations are small; (3) the correlations fluctuate strongly when measured over different subsets of patients. A possible biological explanation for these properties is discussed.
