RESUMO

In the past two decades, several scholars from different disciplines have conducted theoretical research and practical explorations on the issue of psychological capital and achieved certain research results. Yet, few studies have synthesized the psychological capital related to academic outcomes among university students. Thus, the aim of this article is to explore how PsyCap is described in an academic context and how PsyCap and academic-related outcomes are related. A comprehensive systematic review was conducted on 43 studies between 2012 and 2022, sourced from six leading databases: Web of Science, Scopus, ERIC, PsyINFO (EBSCO), Springerlink, and ScienceDirect. Our selection criteria focused on empirical research that specifically discussed PsyCap's impact on university students' academic performance. This review identifies personal and social factors that influence the development of PsyCap in university students, such as self-esteem, motivation, gratitude, family support, and peer relationships. We found that PsyCap plays a key role in academic outcomes, including academic performance, engagement, burnout, adjustment, stress, and intrinsic motivation. Highlighting the significance of PsyCap in academic settings, our study underscores the need for further research on its relationship with student outcomes. Given the substantial influence of PsyCap on academic performance, institutions should consider incorporating psychological capital development programs into their curriculum. Such initiatives could optimize the academic achievements and holistic well-being of students.

RESUMO

Objective: To evaluate the efficacy and safety of Shenqi Fuzheng Injection (SFI) combined with platinum-based chemotherapy (PBC) for the treatment of advanced non-small cell lung cancer (NSCLC). Methods: Seven electronic databases, including CNKI and Wanfang, were comprehensively searched to screen randomized controlled trials (RCTs) until May 1, 2022. The quality of each trial was evaluated according to the Cochrane Handbook for Systematic Reviews of Interventions, and systematic reviews were conducted according to the PRISMA guidelines. Statistical analysis was performed using Review Manager 5.3, and the results were expressed as relative risk (RR) and 95% confidence interval (95% CI). The primary outcome measures were objective response rate (ORR) and disease control rate (DCR). The secondary outcome measures were quality of life and toxicity. Subgroup analysis was performed according to the number of days of SFI single-cycle treatment and combined PBC regimen. Results: A total of 44 RCTs involving 3475 patients were included in the study. The meta-analysis results showed that, compared with PBC alone, SFI combined with PBC significantly improved the ORR (RR = 1.27, 95% CI = 1.18-1.37, P < 0.00001), DCR (RR = 1.12, 95% CI = 1.08-1.15, P < 0.00001), and quality of life (RR = 1.41, 95% CI = 1.31-1.52, P < 0.00001). It also reduced chemotherapy-induced hemoglobin reduction (RR = 0.57, 95% CI = 0.48-0.67, P < 0.00001), leukopenia (RR = 0.61, 95% CI = 0.53-0.71, P < 0.00001), thrombocytopenia (RR = 0.62, 95% CI = 0.55-0.70, P < 0.00001), and simple bone marrow suppression (RR = 0.55, 95% CI = 0.41-0.73, P < 0.0001). Nausea and vomiting (RR = 0.63, 95% CI = 0.52-0.77, P < 0.00001), diarrhea (RR = 0.48, 95% CI = 0.37-0.64, P < 0.00001), and simple digestive tract reactions (RR = 0.63, 95% CI = 0.49-0.80, P = 0.0002) also decreased with the treatment of SFI. Conclusion: SFI combined with PBC for the treatment of advanced NSCLC improved the ORR, DCR, and quality of life, and reduced the incidence of myelosuppression and gastrointestinal adverse reactions. However, considering the limitations of existing evidence, further verification using high-quality RCTs is required.

RESUMO

Seeking academic help has a positive impact on students' ability to handle challenges, leading to improved academic success. As the academic landscape becomes more competitive, the importance of students seeking and using academic support is widely recognized for enhancing their learning experience and achievements. The main objective of this study is to review the prior literature that has examined the academic support provided to college students, addressing the knowledge and methods required in an academic help-seeking process. Based on a systematic literature review, this study's data were gathered from a review of 55 documents from the 11 years between 2012 and 2022. The literature was then individually analyzed using the ATLAS.ti 22 programs. The analysis shows five central themes: (1) Defining student help-seeking; (2) Academic help-seeking and academic performance; (3) Resources of academic help-seeking; (4) Factors of academic help-seeking; (5) Academic Help Seeking Online. This study also identifies potential new directions for future research that could be useful to school administrators in developing policies to assist students with help-seeking behavior, which could have significant implications for the theoretical development and practical guidance of student help-seeking behavior.

RESUMO

Chimeric antigen receptor (CAR) T-cells are an emerging therapy for the treatment of relapsed/refractory B-cell malignancies. While CD19 CAR-T cells have been FDA-approved, CAR T-cells targeting CD22, as well as dual-targeting CD19/CD22 CAR T-cells, are currently being evaluated in clinical trials. This systematic review and meta-analysis aimed to evaluate the efficacy and safety of CD22-targeting CAR T-cell therapies. We searched MEDLINE, EMBASE, Web of Science, and the Cochrane Central Register of Controlled Trials from inception to March 3rd 2022 for full-length articles and conference abstracts of clinical trials employing CD22-targeting CAR T-cells in acute lymphocytic leukemia (ALL) and non-Hodgkin's lymphoma (NHL). The primary outcome was best complete response (bCR). A DerSimonian and Laird random-effects model with arcsine transformation was used to pool outcome proportions. From 1068 references screened, 100 were included, representing 30 early phase studies with 637 patients, investigating CD22 or CD19/CD22 CAR T-cells. CD22 CAR T-cells had a bCR of 68% [95% CI, 53-81%] in ALL (n= 116), and 64% [95% CI, 46-81%] in NHL (n= 28) with 74% and 96% of patients having received anti-CD19 CAR T-cells previously in ALL and NHL studies respectively. CD19/CD22 CAR T-cells had a bCR rate of 90% [95% CI, 84-95%] in ALL (n= 297) and 47% [95% CI, 34-61%] in NHL (n= 137). The estimated incidence of total and severe (grade ≥3) CRS were 87% [95% CI, 80-92%] and 6% [95% CI, 3-9%] respectively. ICANS and severe ICANS had an estimated incidence of 16% [95% CI, 9-25%] and 3% [95% CI, 1-5%] respectively. Early phase trials of CD22 and CD19/CD22 CAR T-cells show high remission rates in ALL and NHL. Severe CRS or ICANS were (1)rare and dual-targeting did not increase toxicity. Variability in CAR construct, dose, and patient factors amongst studies limits comparisons, with long-term outcomes yet to be reported.

RESUMO

This review aimed to update the clinical practice guidelines for managing children and adolescents with 22q11.2 deletion syndrome (22q11.2DS). The 22q11.2 Society, the international scientific organization studying chromosome 22q11.2 differences and related conditions, recruited expert clinicians worldwide to revise the original 2011 pediatric clinical practice guidelines in a stepwise process: (1) a systematic literature search (1992-2021), (2) study selection and data extraction by clinical experts from 9 different countries, covering 24 subspecialties, and (3) creation of a draft consensus document based on the literature and expert opinion, which was further shaped by survey results from family support organizations regarding perceived needs. Of 2441 22q11.2DS-relevant publications initially identified, 2344 received full-text reviews, including 1545 meeting criteria for potential relevance to clinical care of children and adolescents. Informed by the available literature, recommendations were formulated. Given evidence base limitations, multidisciplinary recommendations represent consensus statements of good practice for this evolving field. These recommendations provide contemporary guidance for evaluation, surveillance, and management of the many 22q11.2DS-associated physical, cognitive, behavioral, and psychiatric morbidities while addressing important genetic counseling and psychosocial issues.

RESUMO

The 22q11.2 deletion syndrome (22q11.2DS) is a multisystem disorder with an estimated prevalence of 1:3000 live births. Manifestations show a marked variability in expression and include speech- and language delay, intellectual disability, and neuropsychiatric disorders. We aim to provide an overview of ocular findings in 22q11.2DS in order to optimize recommendations for ophthalmic screening. We combined results from a systematic literature review with results from a multicenter cross-sectional study of patients with 22q11.2DS who were assessed by an ophthalmologist. Our systematic literature search yielded four articles, describing 270 patients. We included 132 patients in our cross-sectional study (median age 8.9 [range 0-56] years). Most reported ocular findings were retinal vascular tortuosity (32%-78%), posterior embryotoxon (22%-50%), eye lid hooding (20%-67%), strabismus (12%-36%), amblyopia (2%-11%), ptosis (4%-6%), and refractive errors, of which hyperopia (6%-48%) and astigmatism (3%-23%) were most common. Visual acuity was (near) normal in most patients (91%-94%). Refractive errors, strabismus, and amblyopia are treatable conditions that are frequently present in patients with 22q11.2DS and should be corrected at an early stage. Therefore, in 22q11.2DS, we recommend ophthalmic and orthoptic screening at the age of 3 years or at diagnosis, and a low-threshold referral in adults.

RESUMO

Oculo-auriculo-vertebral spectrum (hemifacial microsomia/OAVS, OMIM #164210) is a heterogenous and congenital condition caused by a morphogenesis defect of the first and second pharyngeal arches. Etiology includes unknown genetic, environmental factors and chromosomal alterations, which 22q11.2 region is the most frequently reported. Several candidate genes for OAVS have been proposed; however, none has been confirmed as causative of the phenotype. This review aims to sum up all clinical and molecular findings in 22q region of individuals diagnosed with OAVS and to investigate genes that may be involved in the development of the spectrum. A search was performed in PubMed using all entry terms to OAVS and Chromosome 22q11. After screening, 11 papers were eligible for review. Deletions and duplications in the q11.2 region were the most frequent (18/22) alterations reported and a total of 68 genes were described. Our systematic review reinforces the hypothesis that 22q11 region is a candidate locus for OAVS as well as CLTCL1, GSC2, HIRA, MAPK1, TBX1, and YPEL1 as potential candidates genes for genotype-phenotype correlation. Complementary studies regarding genes interaction involved in the 22q11 region are still necessary in the search for a genotype-phenotype association, since the diagnosis of OAVS is a constant medical challenge.

RESUMO

Introdução: No contexto do Sistema Único de Saúde, o conceito da prevenção quaternária adentra timidamente os níveis de atenção à saúde, no entanto, sofre expansão significativa no âmbito da atenção primária à saúde. Objetivo: Identificar por meio da sistematização de evidências científicas, as contribuições técnicas e socioculturais da prevenção quaternária no âmbito da atenção primária à saúde no Brasil. Métodos: Trata-se de uma revisão integrativa de estudos presentes nas bases de dados científicas da Scientific Electronic Library Online, Biblioteca Virtual em Saúde, biblioteca virtual da Comissão de Aperfeiçoamento de Pessoal do Nível Superior e MEDLINE via PubMed com a utilização dos descritores "prevenção quaternária" e "atenção primária à saúde", em inglês e português. Resultados: O corpus de análise foi composto por 22 artigos, sendo que a produção científica sobre o tema se deu de forma mais intensa a partir do ano de 2015 e, em sua maioria, possuíam como abordagem metodológica ensaios teóricos. Dentre as contribuições técnicas destacaram-se a introdução do ensino da prevenção quaternária de modo continuado aos graduandos e profissionais; a construção de protocolos e documentos de amparo profissional; a utilização de modelos explicativos dinâmicos na socialização do quadro clínico; a conduta profissional com os usuários e as contribuições socioculturais envolvendo mudanças na percepção profissional e comunitária sobre o fenômeno saúde-doença, assim como o incentivo a práticas de desmedicalização sociocultural em relação à dor, incapacidade, desconforto, envelhecimento, nascimento e morte. Conclusão: Apesar do reconhecimento das potencialidades da prevenção quaternária, faz-se necessário fortalecer estratégias que possibilitem o desenvolvimento de políticas públicas para fomentar e gerenciar alianças estratégicas com tomadores de decisão, profissionais de saúde e cidadãos, para fomentar a redução de diagnósticos e tratamentos excessivos, contribuindo com a qualidade do cuidado.


Introduction: In the context of the Unified Health System, the concept of quaternary prevention shyly enters the levels of health care, however, undergoes significant expansion in the scope of primary health care. Objective: To identify, through the systematization of scientific evidence, the technical and socio-cultural contributions of quaternary prevention within the scope of primary health care in Brazil. Methods: This is an integrative review of studies present in the scientific databases of the Scientific Electronic Library Online, Regional Portal of the Virtual Health Library of the Latin American and Caribbean Center on Health Sciences Information of the Pan American Health Organization, virtual library of the Higher Education Personnel Improvement Commission, and MEDLINE through PubMed using the descriptors "quaternary prevention" and "primary health care", in English and Portuguese. Results: The corpus of analysis consisted of 22 articles, and the scientific production on the topic took place more intensively from the year 2015 and, for the most part, had theoretical essays as methodological approach. Among the technical contributions, we highlight the introduction of teaching on quaternary prevention in a continuous way to undergraduates and professionals; the construction of protocols and documents of professional support; the use of dynamic explanatory models in the socialization of the clinical picture and professional conduct with users and socio-cultural contributions involve changes in the professional and community perception about the phenomenon of illness and health conception, as well as the incentive to practices of socio-cultural demedicalization in relation to pain, disability, discomfort, aging, birth, and death. Conclusion: Despite the recognition of the potential of quaternary prevention, it is necessary to strengthen strategies that enable the development of public policies to foster and manage strategic alliances with decision makers, health professionals and citizens, to promote the reduction of excessive diagnoses and treatments, contributing to the quality of care.

RESUMO

The 22q11.2 deletion syndrome (22q11.2DS) is present in approximately 5 to 8% of patients with cleft lip, palate, or both (CL/P) and 75 to 80% of patients with congenital heart disease (CHD). In a literature review, we consider this association of 22q11.2DS in pediatric patients with CL/P and CHD. Early diagnosis of 22q11.2DS in pediatric patients with CL/P and CHD helps to optimize a multidisciplinary treatment approach for 22q11DS. Early diagnosis, thereby, can improve quality of life for these patients and awareness of other potential clinical implications that may require attention throughout the patient's life.

RESUMO

22q11.2 deletion syndrome (DS) is considered to be the most robust genetic model of psychosis. In the last decade, there has been increased interest in the brain abnormalities associated with these genetic changes. Most imaging findings in this population come from small samples. This increases the risk of reporting spurious effects that reflect the idiosyncrasies of each study. Thus, the current work is aimed at identifying whether there are spatially consistent structural and functional brain abnormalities in individuals with 22q11.2 DS through (i) a comprehensive label-based systematic review and (ii) a coordinate-based meta-analysis of magnetic resonance imaging studies. The systematic review identified the frontal middle gyri, posterior cingulum, right cuneus and bilateral precuneus as the most affected regions. The meta-analysis revealed consistent abnormalities in the bilateral inferior parietal lobe, right precuneus, right superior temporal gyrus and posterior cingulate cortex. This study provides an important starting point for future research as it sheds light on possible genetically determined psychosis susceptibility regions.

RESUMO

BACKGROUND: Chromosome 22q11.2 microdeletion syndrome, a disorder caused by heterozygous loss of genetic material in chromosome region 22q11.2, has a broad range of clinical symptoms. The most common congenital anomalies involve the palate in 80% of patients, and the heart in 50-60% of them. The cause of the phenotypic variability is unknown. Patients usually harbor one of three common deletions sizes: 3, 2 and 1.5 Mb, between low copy repeats (LCR) designated A-D, A-C and A-B, respectively. This study aimed to analyze the association between these 3 deletion sizes and the presence of congenital cardiac and/or palatal malformations in individuals with this condition. A systematic review and meta-analysis were conducted, merging relevant published studies with data from Chilean patients to increase statistical power. RESULTS: Eight articles out of 432 were included; the data from these studies was merged with our own, achieving a total of 1514 and 487 patients to evaluate cardiac and palate malformations, respectively. None of the compared deleted chromosomal segments were statistically associated with cardiac defects (ORAB v/s AC-AD: 0.654 [0.408-1.046]; OR AD v/s AB-AC: 1.291 [0.860-1.939]) or palate anomalies (ORAB v/s AC-AD: 1.731 [0.708-4.234]; OR AD v/s AB-AC: 0.628 [0.286-1.382]). CONCLUSIONS: The lack of association between deletion size and CHD or PA found in this meta-analysis suggests that deletion size does not explain the incomplete penetrance of these 2 major manifestations, and that the critical region for the development of heart and palatal abnormalities is within LCR A-B, the smallest region of overlap among the three deletion sizes.

RESUMO

The 22q11.2 deletion syndrome (22q11.2DS) is a multisystem condition and the most prevalent microdeletion syndrome in humans. Approximately 25% of individuals with 22q11.2DS receive antipsychotic treatment. To assess whether patients with 22q11.2DS are vulnerable to adverse effects of antipsychotic medication, we carried out a literature review. A systematic search strategy was performed using PubMed (Medline), Embase, PsychInfo, and Cochrane Database of Systematic Reviews. Publications describing adverse effects of antipsychotic medication in patients with 22q11.2DS were included in the review and assessed for their methodological quality. A total of 11 publications reporting on eight trials, cross-sectional or cohort studies, and 30 case reports were included. The most commonly reported adverse effects can be classified into the following categories: movement disorders, weight gain, seizures, cardiac side effects, and cytopenias. Many of these symptoms are manifestations of 22q11.2DS, also in the absence of antipsychotic medication. Based on the reviewed literature, a causal relation between antipsychotic medication and the reported adverse effects could not be established in the majority of cases. Randomized clinical trials are needed to make firm conclusions regarding risk of adverse effects of antipsychotics in patients with 22q11.2DS.

RESUMO

22q11.2 deletion syndrome (22q11.2 DS) is widely known as one of the most compelling genetic models of schizophrenia so far, being almost 40% of the carriers affected by psychotic symptoms. Moreover, most of these subjects also show impairment in social cognition, which is a comprehensive array of function that guides social interaction with the others, leading as well to the acquisition of new cognitive and social skills. In the last decade researchers have argued whether social cognition dysfunctions could be underlined by specific genetic alterations, and whether these are linked to specific clinical features. Some valid candidate genes are RTN4R, that encodes a protein which inhibits axonal sprouting, DGCR8, crucial in mRNA processing, or catechol-O-methyltransferase (COMT) and proline oxydase 1 (PRODH), involved in catecholamine metabolism in frontal cortex. This is the first article to address the topic of social cognition in 22q11.2 DS from a wide perspective, with a highlight on its genetic characteristics. We will provide a narrative review of the most recent findings and we will point out new directions on this research path, in order to achieve an effective characterization of the neurobiological system underlying social behavior.

RESUMO

The 22q11 deletion syndrome (22q11DS) is one of the most common genomic disorders in humans, affecting around 1:2,000 to 1: 4,000 people. 22q11DS affects multiple body systems and is associated with multiple physical problems. Given the high rate of physical morbidity associated with the 22q11DS, it was hypothesized that it would exert a high psychosocial impact on patients and their relatives. To investigate this, a systematic review of the literature and narrative synthesis was performed. Three major themes emerged. First, the complex and conflicting emotions experienced by family members resulting from the diagnosis. Second, the pervasive educational and health-care challenges associated with the diagnosis and third that people affect by 22q11DS strived for individualism. The results of this review help to inform clinical management of families with 22q11DS.

RESUMO

BACKGROUND: We examined the usefulness of the nuclear matrix protein 22 (NMP22) BladderChek test for detecting bladder cancer. MATERIALS AND METHODS: A literature search was performed using PubMed, Embase, the Cochrane Library, and Web of Science. The diagnostic accuracy of the NMP22 BladderChek test was evaluated via pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and area under curve (AUC). Inter-study heterogeneity was explored using meta-regression and subgroup analyses. RESULTS: We included 23 studies in the systematic review and 19 in the quantitative meta-analysis. Overall sensitivity and specificity were 56% (52-59%) and 88% (87-89%), respectively; pooled PLR and NLR were 4.36 (3.02-6.29) and 0.51 (0.40-0.66), respectively; DOR was 9.29 (5.55-15.55) with an AUC of 0.8295. The mean sensitivity for Ta, T1, ≥ T2, Tis, G1, G2, and G3 disease was 13.68%, 29.49%, 74.03%, 34.62%, 44.16%, 56.25%, and 67.34%, respectively. CONCLUSIONS: The NMP22 BladderChek test shows good discrimination ability for detecting bladder cancer and a high-specificity algorithm that can be used for early detection to rule out patients with higher bladder cancer risk. It also has better potential for screening higher-grade and higher-stage tumors, and better diagnostic performance in Asians.

RESUMO

The behavioural phenotype of 22q11.2 deletion syndrome syndrome (22q11DS), one of the most common human multiple anomaly syndromes, frequently includes intellectual disability (ID) together with high risk of diagnosis of psychotic disorders including schizophrenia. Candidate cognitive endophenotypes include problems with retrieval of contextual information from memory and in executive control and focussing of attention. 22q11DS may offer a model of the relationship between ID and risk of psychiatric disorder. This paper reviews research on the relationship between the cognitive phenotype and the development of psychiatric disorders in 22q11DS. Aspects of cognitive function including verbal I.Q., visual memory, and executive function, are associated with mental health outcome in people with 22q11DS. This relationship may result from a common neurobiological basis for the cognitive difficulties and psychiatric disorders. Some of the cognitive difficulties experienced by people with 22q11DS, especially in attention, memory retrieval, and face processing, may, however, in themselves constitute risk factors for development of hallucinations and paranoid delusions. Future research into factors leading to psychiatric disorder in people with 22q11DS should include assessment of social and psychological factors including life events, symptoms associated with trauma, attachment, and self-esteem, which together with cognitive risk factors may mediate mental health outcome.

RESUMO

Waardenburg syndrome (WS) is a neurocristopathy characterized by pigmentation abnormalities of the skin, hair, and iris, as well as sensorineural hearing loss. Contiguous gene deletions encompassing SOX10 are rare, which limits conclusions about genotype-phenotype correlation regarding patient prognosis and management. This study adds to the existing body of knowledge by characterizing a 2.4 Mb deletion [arr[hg19] 22q12.3-q13.1 (36467502-38878207)x1] encompassing SOX10 and 53 additional RefSeq genes in a 15-year-old female with atypical WS. The patient presented with developmental delay, profound bilateral sensorineural hearing loss, heterochromia iridis, hypotonia, and bilateral finger contractures. Published genomic and phenotypic profiles of patients with SOX10-encompassing deletions point toward several plausible candidate gene that could account for the considerable clinical heterogeneity. These studies suggest the existence of modifiers among the co-deleted, dosage-sensitive genes (e.g., MYH9) and among genes whose effect may depend on the unmasking of recessive mutations (e.g., PLA2G6). Finally, we highlight evidence illustrating extensive interconnectivity of SOX10-hypothesizing that haploinsufficiency of SOX10 may "unmask" subtler effects on expression or epistasis associated with variants in SOX10 targets (e.g., DHH), in its partners (e.g., PAX3, EGR2), and in genes with functional overlap (e.g., SOX8, SOX9).

RESUMO

A toxicologic and dermatologic review of 1-(2,4-dimethyl-3-cyclohexenyl)-2,2-dimethylpropan-1-one when used as a fragrance ingredient is presented. 1-(2,4-Dimethyl-3-cyclohexenyl)-2,2-dimethylpropan-1-one is a member of the fragrance structural group Alkyl Cyclic Ketones. These fragrances can be described as being composed of an alkyl, R1, and various substituted and bicyclic saturated or unsaturated cyclic hydrocarbons, R2, in which one of the rings may include up to 12 carbons. Alternatively, R2 may be a carbon bridge of C2-C4 carbon chain length between the ketone and cyclic hydrocarbon. This review contains a detailed summary of all available toxicology and dermatology papers that are related to this individual fragrance ingredient and is not intended as a stand-alone document. Available data for 1-(2,4-dimethyl-3-cyclohexenyl)-2,2-dimethylpropan-1-one were evaluated then summarized and includes physical properties, acute toxicity, skin irritation, sensitization, and genotoxicity data. A safety assessment of the entire Alkyl Cyclic Ketones will be published simultaneously with this document; please refer to Belsito et al. (Belsito, D., Bickers, D., Bruze, M., Calow, P., Dagli, M., Fryer, A.D., Greim, H., Miyachi, Y., Saurat, J.H., Sipes, I.G., 2013. A Toxicologic and Dermatologic Assessment of Alkyl Cyclic Ketones When Used as Fragrance Ingredients (submitted for publication)) for an overall assessment of the safe use of this material and all Alkyl Cyclic Ketones in fragrances.
