Having children admitted in the intensive care unit is a demanding experience for parents. They encounter several difficulties during this process, and it is important to properly identify their psychosocial needs for the health team to address appropriately.

The aim of the study is to identify the psychosocial needs encountered by parents of children in pediatric intensive care units in Brazil.

A descriptive study with a qualitative approach was used to increase understanding of psychosocial experiences of parents. Individual semi-structured interviews were conducted with 11 parents of hospitalized children in pediatric intensive care units in Brazil. Thematic analysis was used to analyze the data. The university ethics review committee approved the research protocol. All parents were informed on study details and provided written consent prior to the interview.

Four themes were constructed 1) Support from family and peers; 2) Support from the healthcare team; 3) Parental role; and 4) Emotional recovery. Parents expressed diverse psychosocial needs based on family and peer social support, child's clinical condition, as well as the structure, norms, and routines of health care teams during hospitalization.

The findings highlight the importance of nursing assessment of psychosocial experiences encountered by parents of children in pediatric intensive care units, which will guide planning of individualized interventions and to increase family-centered care in pediatric intensive care units.

Natural killer (NK) cells play an important role in defense against tumor cells. The development and function of NK cells is governed by a dynamic balance between inhibition and activation of cell surface receptors, including KIR receptors.

A case-control study is carried out that compares a group of 46 children diagnosed with malignant diseases, the control group is made up of 82 healthy children. KIRs genes, haplotypes and ligands were determined and compared between groups.

There are no differences in KIRs genes, KIRs haplotypes or in KIRs gene ligands between groups. However, when KIRS and ligands were jointly studied, k2DS1_C2 was significantly higher in the group of cancer children (p=0.016).

Our results do not provide evidence of an association between pediatric cancer disease with genotypes and groups of genes KIRs. The k2DS1_C2 genotype could predispose to susceptibility to malignant processes in children.

They provide a setting in which patients can immediately inform themselves about the medication they are taking or reread any content provided by physicians or pharmacists, as needed. Despite the growing number of people who are at risk of vision impairement, some pharmaceutical companies print MPPLs and PILs in fonts that patients cannot read. Problems arising from MPPLs and PILs have been identified as remarkable sources of medication errors and fatalities. As a result, the purpose of this article is to emphasize the need for patient-centered MPPLs and PILs to protect public health.
The objective of this case report is to highlight the possibility of the second-generation antipsychotic ziprasidone causing a false positive result for fentanyl on a urine drug screen (UDS).

A 70-year-old female was admitted to an inpatient psychiatric unit for treatment of a manic episode of bipolar I disorder. She had no previous history of a substance use disorder (SUD) and had no previous positive results on UDS tests spanning an 8-year period. However, her UDS obtained in the emergency department (ED) was positive for fentanyl. The patient adamantly denied that she had ingested anything other than her prescribed medications. Her outpatient psychiatric provider also endorsed that she had no previous known history of an SUD. It was suspected that the patient's treatment with ziprasidone prior to admission and in the ED contributed to this positive fentanyl result.

It has been established that risperidone may cause false positive fentanyl results on UDS. Due to structural similarities, ziprasidone may also cause this same result. As clinicians become more aware of the ubiquity of fentanyl in the illicit drug supply, it is imperative that clinicians also consider limitations of the currently available UDSs.

Rituximab (RTX) is a chimeric monoclonal antibody targeting the CD20 antigen, which has been used in the treatment of autoimmune neuropathies, although the efficacy of RTX remains unclear. A literature search was performed using Medline, Embase and Cochrane Register for studies between 2000 and 2021 using the search terms "Chronic inflammatory demyelinating polyneuropathy" OR "Multifocal motor neuropathy" OR "Myelin associated glycoprotein" OR "Distal acquired demyelinating neuropathy" OR "Multifocal acquired demyelinating sensory and motor neuropathy" OR "demyelinating neuropathy" AND "Rituximab". Twenty-three studies were included, of which two were randomised controlled trials, 6 prospective studies and 15 retrospective studies. RTX was effective in 63% of CIDP patients, 48% of anti-MAG neuropathy, and 96% of patients with autoimmune nodopathy. Neurophysiological improvement was evident in 58% of CIDP and 40% of anti-MAG neuropathy patients. Low rates of serious adverse events (2.6%) were observed. These results indicate that RTX has potential as a treatment in immune mediated polyneuropathy, although the quality of evidence supporting its use it poor. Randomized controlled trials are required to reliably establish the efficacy and safety of RTX. Trial registration number CRD42020179666.Eosinophilic fasciitis (EF) is a rare disorder characterized by muscle stiffness mimicking other neuromuscular diseases. The diagnosis of EF is made on the basis of typical skin lesions. We report a case of a 36-year-old male patient with suspected stiff-person syndrome (SPS), who presented with progressive limb muscle stiffness and limited mobility of both wrists without obvious skin changes. Ultrasound revealed fascial thickening of bilateral upper and lower limb muscles and enlargement of hypoechoic tissues around the flexor digitorum tendons of the wrist. Skin and fascia biopsy confirmed the diagnosis of EF. Prednisolone therapy resulted in the improvement of muscle stiffness and tightness. Our findings suggest the need to consider connective tissue diseases such as EF in a patient with atypical features of SPS. Ultrasound is helpful for visualizing the causes of muscle stiffness and joint contractures in EF patients.The aim of this study was to evaluate the impact of drainless parotidectomy using fibrin sealant on length of stay, post-operative seroma and related complications. For this purpose, a retrospective matched case-control series was held in a single academic center. SB 204990 order All patients who underwent drainless parotidectomies, including deep lobe tumors and revision surgeries, were compared to matched controls in which a suction drain was inserted. Main outcomes were length of hospital stay and post-operative seroma. A total of 123 patients (41 cases and 82 controls) were included in the study. Fibrin sealant group had higher rates of total parotidectomy compared with the control group (25.0% vs. 10.5%, p = 0.054). Length of stay was significantly shorter in the fibrin sealant group (1.0 ± 0.3 days vs. 1.5 ± 0.6 days, p less then 0.001, respectively). No statistically significant difference was found between the fibrin sealant group and the control regarding post-operative seromas (9.8% vs. 14.6%, p = 0.574, respectively), aspirations rate (7.3% vs. 14.6%, p = 0.381), and infection rates (0% vs.3.7%, p = 0.550). In conclusion, drainless parotidectomy does not increase post operative seroma rates and related complications, and can also be implemented for revision surgery.
Sclerodermoid graft-versus-host disease (GVHD) is the most severe form of chronic GVHD (cGVHD) and represents a considerable therapeutic challenge. Due to the scarcity of human studies on sclerodermoid cGVHD, the pathogenesis of this entity is not fully understood.

To identify the differential expression of fibrosis-related genes in skin lesions of human lichenoid and sclerodermoid cGVHD and to assess the expression of their corresponding proteins.

PCR array analysis was performed on RNA extracted from three skin biopsies of sclerodermoid cGVHD patients and three normal skin samples, for fibrosis-related gene expression profiles followed by evaluation of their corresponding protein expressions. The expressions of Tissue inhibitor of metalloproteinase 3 (TIMP3), matrix metalloproteinase 1 (MMP1), TIMP1, and TIMP2 were further studied by immunohistochemistry. Demographic, clinical and immunohistochemical parameters of the two cGVHD groups and the control group were compared. The Pearson correlation coefficient was used to assess the correlation between data among the study groups.

We identified 44 upregulated and 14 downregulated genes in the skin samples of sclerodermoid cGVHD compared to the control group. TIMP3 was positive in 13/21 biopsies of cGVHD and in one biopsy of the control group. The average staining intensity was significantly higher in the cGVHD group compared to the control group. TIMP3 was expressed mainly in dermal blood vessels. cGVHD specimens with positive TIMP3 staining had a statistically significantly higher total microvascular area than the negative specimens.

TIMP3 levels are increased in both subtypes of cGVHD and are associated with increased dermal vascularity.

Recent applications of single-cell technologies to Plasmodium have enabled the systematic investigation of the distinct stages across the life cycle. Most single-cell data have focused on the parasite exclusively, but a few studies have started to profile both parasite and host cells to shed light on the heterogeneity of cell states that underpin host-parasite interactions. In this opinion article, we highlight how atlasing initiatives are starting to be used to infer functional interactions between parasite and host and could be a powerful tool in drug discovery and vaccine development.
