The impact of intensive treatment for pediatric anxiety and obsessive-compulsive disorder on daily functioning

This study investigated whether intensive group-based cognitive-behavioral therapy (CBT) with family involvement for children with anxiety disorders and obsessive-compulsive disorder (OCD) would facilitate children’s return to their daily routines. The focus shifted from the usual emphasis on remission to an improvement in functioning. The aim was to capture potentially missed gains when children pursue their fears and engage in more adaptive behaviors as these efforts may result in ongoing symptoms. Two hundred twelve children and adolescents aged 8–19 years old, who were patients in an intensive outpatient group-based treatment program at an academic hospital, participated in this study. Results indicated that both children and their parents endorsed significant improvement in children’s functioning from admission to discharge. Symptom reduction was assessed for reference, and both children and parents reported significant decreases in child anxiety symptoms from admission to discharge, and children endorsed decreases in their comorbid depression symptoms. Short-term group-based intensive treatment in a clinical setting may help children return to their daily activities quickly.
Does metabolic status affect serum levels of BDNF and MMP-9 in patients with schizophrenia?

Abstract The purpose of the article: Brain-derived neurotrophic factor (BDNF) and matrix metalloproteinase-9 (MMP-9) are involved in the processes of neurogenesis, synaptic plasticity, learning and memory. Growing number of studies shows a relationship between BDNF or MMP-9 and schizophrenia. Also, BDNF and MMP-9 levels may be affected by metabolic parameters, such as obesity or dyslipidemia. Our hypothesis is that alterations of BDNF or MMP-9 levels in schizophrenia might be secondary to metabolic abnormalities, often found among schizophrenia patients. Materials and methods: We have compared BDNF and MMP-9 between patients with schizophrenia (n = 64, age 49 ± 8.2 y) and healthy controls (n = 32, age 51 ± 8.9 y) in the context of cardio-metabolic parameters. Serum levels of BDNF and MMP-9 were measured using ELISA test, body composition parameters were determined using bioelectric impedance analysis. Results and conclusions: Our results showed significantly lowered serum BDNF concentration in the schizophrenia group (schizophrenia: 23.8 ± 7.83 ng/mL, control: 27.69 ± 8.11 ng/mL, p = 0.03). Serum MMP-9 concentration in schizophrenia group did not differ compared with the control group (schizophrenia: 456.8 ± 278.4 ng/mL, control: 341.5 ± 162.4 ng/mL, p = 0.07). After adjusting for age, all anthropometric parameters, body composition and laboratory tests BDNF were still significantly lower in the schizophrenia group. However, MMP-9 became significantly elevated in the schizophrenia group after adjusting for several anthropometric and body composition covariates. Our results confirmed reduced serum BDNF concentration in patients with schizophrenia. Also, this reduction seems to be independent of metabolic abnormalities. On the other hand, our hypothesis that MMP-9 level in schizophrenia is altered due to metabolic abnormalities might be true.
Evolution and Genetic Diversity of Porcine Circovirus 3 in China

The identification of a new circovirus (Porcine Circovirus 3, PCV3) has raised concern because its impact on swine health is not fully known. In Fujian Province in eastern China, even its circulating status and genetic characteristics are unclear. Here, we tested 127 tissue samples from swine from Fujian Province that presented respiratory symptoms. All of the PCV3 positive samples were negative for many other pathogens involved in respiratory diseases like PCV2, PRRSV, and CSFV, suggesting that PCV3 is potentially pathogenic. From phylogenetic analysis, PCV3 strains are divided into two main clades and five sub-clades; PCV3a-1, PCV3a-2, PCV3a-3, PCV3b-1, and PCV3b-2. Our identified strains belong to genotypes PCV3a-1, PCV3a-2, PCV3a-3, and PCV3b-2, indicating a high degree of genetic diversity of PCV3 in Fujian province until 2019. Interestingly, we found the time of the most recent common ancestor (tMRCA) of PCV3 was dated to the 1950s, and PCV3 has a similar evolutionary rate as PCV2 (the main epidemic genotypes PCV2b and PCV2d). In addition, positive selection sites N56D/S and S77T/N on the capsid gene are located on the PCV3 antigen epitope, indicating that PCV3 is gradually adaptive in swine. In summary, our results provide important insights into the epidemiology of PCV3.
Phase II Study of Avelumab in Patients With Mismatch Repair Deficient and Mismatch Repair Proficient Recurrent/Persistent Endometrial Cancer.

PURPOSE Despite the tissue-agnostic approval of pembrolizumab in mismatch repair deficient (MMRD) solid tumors, important unanswered questions remain about the role of immune checkpoint blockade in mismatch repair-proficient (MMRP) and -deficient endometrial cancer (EC). METHODS This phase II study evaluated the PD-L1 inhibitor avelumab in two cohorts of patients with EC: (1) MMRD/POLE (polymerase ε) cohort, as defined by immunohistochemical (IHC) loss of expression of one or more mismatch repair (MMR) proteins and/or documented mutation in the exonuclease domain of POLE; and (2) MMRP cohort with normal IHC expression of all MMR proteins. Coprimary end points were objective response (OR) and progression-free survival at 6 months (PFS6). Avelumab 10 mg/kg intravenously was administered every 2 weeks until progression or unacceptable toxicity. RESULTS Thirty-three patients were enrolled. No patient with POLE-mutated tumor was enrolled in the MMRD cohort, and all MMRP tumors were not POLE-mutated. The MMRP cohort was closed at the first stage because of futility: Only one of 16 patients exhibited both OR and PFS6 responses. The MMRD cohort met the predefined primary end point of four ORs after accrual of only 17 patients; of 15 patients who initiated avelumab, four exhibited OR (one complete response, three partial responses; OR rate, 26.7%; 95% CI, 7.8% to 55.1%) and six (including all four ORs) PFS6 responses (PFS6, 40.0%; 95% CI, 16.3% to 66.7%), four of which are ongoing as of data cutoff date. Responses were observed in the absence of PD-L1 expression. IHC captured all cases of MMRD subsequently determined by polymerase chain reaction or genomically via targeted sequencing. CONCLUSION Avelumab exhibited promising activity in MMRD EC regardless of PD-L1 status. IHC for MMR assessment is a useful tool for patient selection. The activity of avelumab in MMRP/non-POLE-mutated ECs was low.
Building capacity for aesthetic surgery in Nigeria: perspectives from the cosmetic surgery fellowship at the Ivo Pitanguy Institute Rio de Janeiro, Brazil

Very little of cosmetic surgery procedures were done hitherto in most of the plastic surgery training institutions in Nigeria. The reasons for this are many. The practice and training is tilted significantly in favor of reconstructive surgery compared to aesthetic surgery with a ratio as high as 9:1 in the major teaching and training institutions in the country. As a result, experience is limited in cosmetic surgery and the trainees rarely participate in significant number of cosmetic procedures throughout their training. With the progressive increase in demand for cosmetic surgery locally, concerted efforts must be made to build the capacity of plastic surgeons to meet this growing demand. This article documents the experience of the author during a cosmetic surgery fellowship at the Ivo Pitanguy Institute, Rio de Janeiro, Brazil, and drew perspectives from the experience for the building of capacity for cosmetic surgery in Nigeria.
Pilot Evaluation of a Fully Automated Bioinformatics System for Analysis of Methicillin-Resistant Staphylococcus aureus Genomes and Detection of Outbreaks

Genomic surveillance that combines bacterial sequencing and epidemiological information will become the gold standard for outbreak detection, but its clinical translation is hampered by the lack of automated interpretation tools. We performed a prospective pilot study to evaluate the analysis of methicillin-resistant Staphylococcus aureus (MRSA) genomes using the Next Gen Diagnostics (NGD) automated bioinformatics system. ABSTRACT Genomic surveillance that combines bacterial sequencing and epidemiological information will become the gold standard for outbreak detection, but its clinical translation is hampered by the lack of automated interpretation tools. We performed a prospective pilot study to evaluate the analysis of methicillin-resistant Staphylococcus aureus (MRSA) genomes using the Next Gen Diagnostics (NGD) automated bioinformatics system. Seventeen unselected MRSA-positive patients were identified in a clinical microbiology laboratory in England over a period of 2 weeks in 2018, and 1 MRSA isolate per case was sequenced on the Illumina MiniSeq instrument. The NGD system automatically activated after sequencing and processed fastq folders to determine species, multilocus sequence type, the presence of a mec gene, antibiotic susceptibility predictions, and genetic relatedness based on mapping to a reference MRSA genome and detection of pairwise core genome single-nucleotide polymorphisms. The NGD system required 90 s per sample to automatically analyze data from each run, the results of which were automatically displayed. The same data were independently analyzed using a research-based approach. There was full concordance between the two analysis methods regarding species (S. aureus), detection of mecA, sequence type assignment, and detection of genetic determinants of resistance. Both analysis methods identified two MRSA clusters based on relatedness, one of which contained 3 cases that were involved in an outbreak linked to a clinic and ward associated with diabetic patient care. We conclude that, in this pilot study, the NGD system provided rapid and accurate data that could support infection control practices.
Baseline and Early Predictors of Good Patient Candidates for Second-Line after Sorafenib Treatment in Unresectable Hepatocellular Carcinoma

Background: Recent advances in the development of tyrosine kinase inhibitors (TKIs) have enabled patients with unresectable hepatocellular carcinoma (HCC) to receive multiple TKIs in sequence. The aim of this study was to identify predictors of good candidates for second-line treatment after disease progression during sorafenib treatment. Methods: This is a retrospective cohort study of 190 consecutive HCC patients who were treated with sorafenib in our hospital. Three criteria of good candidates for second-line TKI at the time of disease progression during sorafenib treatment were defined as follows: criterion 1 was the same as the inclusion criteria of the regorafenib for patients with hepatocellular carcinoma who progressed on sorafenib treatment (RESORCE) study, criterion 2 was the inclusion criteria of the RESORCE study plus Child–Pugh score 5, and criterion 3 was the inclusion criteria of the RESORCE study plus albumin–bilirubin (ALBI) grade 1. Factors at baseline and at week 4 during sorafenib treatment were used to predict patients fulfilling each of these three criteria. Results: The distribution of patients was 29%, 13%, and 6% in criteria 1, 2, and 3, respectively. Significant factors for meeting criterion 1 was the combination of baseline albumin >3.7 g/dL (odds ratio (OR) 2.7) plus degree of decrease in albumin (Δalbumin) at week 4 <0.2 g/dL (OR 2.6), or the combination of baseline ALBI score <−2.33 (OR 2.5) and ΔALBI at week 4 <0.255 (OR 4.9). For criterion 2, the value of baseline albumin and ALBI score was identical to criterion 1; however, Δalbumin (<0.1 g/dL) and ΔALBI score (<0.19) became stricter. For criterion 3, the value of baseline albumin (>3.8 g/dL) and ALBI (<−2.55) became stricter, as did Δalbumin (<0.1 g/dL) and ΔALBI (<0.085). Furthermore, tumor burden (>11) was selected as an additional predictor (OR 5.4). Conclusion: Predictors to satisfy the RESORCE study inclusion criteria were as follows: preserved liver function at baseline, as reflected by albumin or ALBI score, and small deterioration of liver function early during sorafenib therapy, as reflected by Δalbumin or ΔALBI at week 4. Liver function at baseline and degree of change in liver function during sorafenib treatment need to be stricter for better outcomes of liver function with disease progression.
Single or double embryo transfer? Decision-making process in patients participating in an oocyte donation program

Abstract In IVF/ICSI programs, after receiving the information about the success results of single embryo transfer (SET) vs double embryo transfer (DET) and the risks of multiple pregnancy, a significant number of patients opt for SET. Up to date, no comparable studies have been published in oocyte recipients. The aim of this study was to evaluate if the counseling provided to oocyte recipients influence their decision on the number of embryos to be transferred. Fifty-five recipients expressed their preference and the relevance for the decision-making process that they attribute to certain factors through an anonymous questionnaire completed pre and post-counseling. Before counseling, 32 out of 55 recipients preferred DET, 13 preferred SET and 10 were undecided. From the 32 recipients who preferred DET, 16 (50%) maintained their preference after counseling, 13 (40.6%) changed their decision to SET and 3 (9.4%) changed to undecided (McNemar’s test: p < .05). After counseling, the patients attached less importance to the probability of pregnancy and more importance to maternal and perinatal risks (p < .05). We conclude that after counseling, a significant number of recipients changed their preferences from DET to SET.
Different volumes and intensities of static stretching affect the range of motion and muscle force output in well-trained subjects

ABSTRACT The manipulation of the volume and intensity of static stretching (SS) can affect the range of motion (ROM) and muscle force output. The purpose of this study was to investigate the effect of two different SS protocols with different intensities (50% and 85% POD) and volumes (120-s and 240-s) on ROM, peak force, and muscle activity during maximal isometric leg curl exercise in well-trained participants. Fifteen young males (age:27.5 ± 6.1years, height:175.6 ± 4.7cm, and body mass:81.5 ± 10.4kg, 6 ± 2 years of resistance training experience) performed passive hip flexion with two different SS protocols: six stretches of 40-s, with 15-sec rest between each stretch at 50% of the point of discomfort (POD) and three stretches of 40-s, with 15-sec rest between each stretch at 85%POD. The passive hip flexion ROM, biceps femoris muscle activation (integrated electromyography: IEMG), and knee flexors force were monitored during a 3-s maximal voluntary isometric leg curl exercise. ROM increased between pre- and post-intervention for both SS protocols (50%POD: p = 0.016, Δ% = 4.6% and 85%POD: p < 0.001, Δ% = 11.42%). Peak force decreased between pre- and post-intervention only for 85%POD (p = 0.004, Δ% = 23.6%). There were no significant IEMG differences. In conclusion, both SS protocols increased ROM, however, the high-intensity and short-duration SS protocol decreased peak force.
Enhancement of indirect functional connections with shortest path length in the adult autistic brain

Autism is a neurodevelopmental condition characterized by atypical brain functional organization. Here we investigated the intrinsic indirect (semi‐metric) connectivity of the functional connectome associated with autism. Resting‐state functional magnetic resonance imaging scans were acquired from 65 neurotypical adults (33 males/32 females) and 61 autistic adults (30 males/31 females). From functional connectivity networks, semi‐metric percentages (SMPs) were calculated to assess the proportion of indirect shortest functional pathways at global, hemisphere, network, and node levels. Group comparisons were then conducted to ascertain differences between autism and neurotypical control groups. Finally, the strength and length of edges were examined to explore the patterns of semi‐metric connections associated with autism. Compared with neurotypical controls, autistic adults displayed significantly higher SMP at all spatial scales, similar to prior observations in adolescents. Differences were primarily in weaker, longer‐distance edges in the majority between networks. However, no significant diagnosis‐by‐sex interaction effects were observed on global SMP. These findings suggest increased indirect functional connectivity in the autistic brain is persistent from adolescence to adulthood and is indicative of reduced functional network integration.
B cell superantigens in the human intestinal microbiota

Bacterial superantigens in the human intestinal microbiota can induce and bind IgA. Bacterial superantigens spur IgA secretion Mucosal IgA is abundant and interacts with the gut microbiome. To examine microbial induction of IgA in humans, Bunker et al. screened microbiota from infants against mouse and human IgA. Unexpectedly, they saw a subset of samples bound IgA in a way that indicated the presence of superantigens, which bind T cell receptors or B cell receptors outside of the typical antigen-binding region, leading to nonspecific activation. Putative superantigens were identified in commensal members of Lachnospiraceae, which activated human VH3-positive B cells and induced IgA production in mice. These data identify commensal superantigens and suggest that they may be dominant forces behind IgA production in humans. IgA is prominently secreted at mucosal surfaces and coats a fraction of the commensal microbiota, a process that is critical for intestinal homeostasis. However, the mechanisms of IgA induction and the molecular targets of these antibodies remain poorly understood, particularly in humans. Here, we demonstrate that microbiota from a subset of human individuals encode two protein “superantigens” expressed on the surface of commensal bacteria of the family Lachnospiraceae such as Ruminococcus gnavus that bind IgA variable regions and stimulate potent IgA responses in mice. These superantigens stimulate B cells expressing human VH3 or murine VH5/6/7 variable regions and subsequently bind their antibodies, allowing these microbial organisms to become highly coated with IgA in vivo. These findings demonstrate a previously unappreciated role for commensal superantigens in host-microbiota interactions. Furthermore, as superantigen-expressing strains show an uneven distribution across human populations, they should be systematically considered in studies evaluating human B cell responses and microbiota during homeostasis and disease.
Perfil genético do ApoE na Demência Genetic profiling of ApoE in Dementia

Dementia is one of the leading causes of disability among the elderly, affecting over 36 million people worldwide. It is characterized by progressive deterioration in cognitive functions that impair the successful performance of daily living activities. Most forms of dementia are progressive in nature, increasing in severity over time, with the rate of symptoms progression and the age at onset differing among the major dementing disorders. The most frequent types of dementia include Alzheimer ́s Disease (AD), Vascular Dementia, Dementia of Lewy bodies and Frontotemporal Dementia. Differential diagnosis of dementia is typically done by neuropsychological testing (for exclusion of other dementias) and neuroimaging investigations. However, many of the clinical symptoms typical of dementia may overlap across dementia subtypes, which may constitute a diagnosis problem leading to lack of specificity and misdiagnosis. Understanding the environmental and genetic factors that modulate risks and outcomes of diseases can open new perspectives on the management of these neurological disorders. Apolipoprotein E gene (ApoE) is recognized as the major genetic risk factor in dementia, in particular playing a central role in AD development, being that ApoE allele ε4 carriers are more susceptible to disease. Furthermore, putative associations have also been proposed between this gene and other neurological disorders, nonetheless controversial data have been reported regarding these aspect. Hence, the aim of this work was to determine ApoE genotypic and allelic frequencies in a pilot study group of dementing patients from the catchment area of the “Hospital de São Sebastião” in “Santa Maria da Feira”. This group was subdivided according to their neurochemical-based diagnosis of dementia, in which Aβ1-42, phospho-Tau 181 and total-Tau levels in patients’ cerebrospinal fluid were evaluated. In this study, we could observe that allele ε3 was the most frequent in the total study group, independent of the type of pathology, and that allele ε2 was the less frequent. Allele ε4 was in fact more frequent in AD patients than in other neurological disease patients, in agreement with the proposed link established by other authors. Additionally, we also find that allele ε4 frequency in patients suffering from amyloid pathology is similar to that observed in AD group, suggesting a role for ApoE in Aβ metabolism and brain accumulation. Potentially, these patients have a higher susceptibility to develop AD pathology in the future. Thus, our data supports the idea that ApoE allele ε4 is a strong risk factor for AD development and that it may be considered as a relevant genetic test that may assist in the clinical diagnosis of dementia.

Study on the Mechanism of Interfacial Friction Heating in Polymer Ultrasonic Plasticization Injection Molding Process

Ultrasonic Plasticization Injection Molding (UPIM) is an effective way to manufacture polymeric micro parts and has great potential for energy saving with processing polymeric materials of a small amount. To better control the UPIM process and improve the quality of micro parts, it is necessary to study the heat generation mechanism. In this paper, the interfacial friction heating process of UPIM was studied by finite element (FEM) simulation and experiment, and the temperature change in the friction interface was estimated. Then, the effects of different process parameters such as ultrasonic frequency and ultrasonic amplitude on the friction heating process were analyzed. The results showed that the rising trend of friction heating temperature was transient (finished within 1 s), and the change trend of FEM simulation was consistent with experimental results. Adjusting ultrasonic frequency and amplitude has a significant influence on the friction heating process. Increasing the ultrasonic frequency and amplitude can improve the efficiency of friction heating.
Singular Rouquier complexes

We generalize the construction of Rouquier complexes to the setting of one‐sided singular Soergel bimodules. Singular Rouquier complexes are defined by taking minimal complexes of restricted Rouquier complexes. We show that they retain many of the properties of ordinary Rouquier complexes: they are Δ$\Delta$ ‐split, they satisfy a vanishing formula, and when Soergel's conjecture holds they are perverse. As an application, we establish Hodge theory for singular Soergel bimodules.
