ABSTRACT

BACKGROUND Noninvasive follicular neoplasm with papillary like nuclear features (NIFTP) reclassification has significantly influenced the field of thyroidology. However, the extent of this impact depends upon the incidence of NIFTP in a given population. In this meta-analysis, we aimed to obtain robust information about the actual incidence of NIFTP worldwide by reviewing the published data. METHODS Comprehensive literature search was performed using electronic databases of PubMed and Web of Science over a 5-year period (01.01.2016-30.01.2021). The incidence of NIFTP was calculated by dividing the number of NIFTP by the number of papillary thyroid carcinoma (PTC). Meta-analysis of proportion and their 95% confidence interval (CI) were pooled using the random-effect model. Heterogeneity across the included studies was assessed using I2 statistics. Egger’s regression test and funnel plot of estimates were used to evaluate the publication bias. P-value < 0.05 was considered significant. RESULTS From 505 publications, we finally included 50 studies, all retrospective, with 100,780 PTC and 3,990 NIFTP from 92 institutions worldwide. Our results demonstrated that the overall incidence of NIFTP was 6.0% (95% confidence interval [CI] = 4.4-8.2) among PTCs or thyroid malignancies with a high level of heterogeneity among the included studies (I2 = 98.6%). NIFTP incidence was largely similar in North America and Europe (9.3% vs. 9.6%) with a significantly lower overall rate from Asia (2.1%). There was a significant decline in the reported incidence of NIFTP in non-Asian studies published after 2017 (p = 0.002). On applying our data on global thyroid cancer statistics, this reclassification would affect ~30,881 patients annually with lower impact in Asia compared to North America and Europe. CONCLUSION This comprehensive meta-analysis confirms that the worldwide NIFTP incidence is much lower than estimated initially. The NIFTP rates are significantly lower in Asian continent as compared to North American and European countries. Apart from geography, NIFTP rates are significantly influenced by the nature of study, type of database used for sample collection and the diagnostic criteria used. Introduction of NIFTP may potentially spare over 30 thousand patients worldwide annually from clinical and psychological consequences of cancer diagnosis.

ABSTRACT

The current descriptive study investigated the correlation between psychological resilience and quality of professional life in clinic nurses. Nurses should have psychological resilience to have high compassion satisfaction and low burnout and compassion fatigue. The sample comprised 280 hospital nurses in Istanbul. Data were analyzed using descriptive statistics and Pearson correlation coefficient. Psychological resilience was positively correlated with compassion satisfaction (r = 0.372; p < 0.01) and negatively correlated with burnout (r = -0.379; p < 0.01) and compassion fatigue (r = -0.336; p < 0.01). Psychological resilience was positively correlated with professional quality of life. Managerial interventions and training should be developed and implemented to help nurses develop psychological resilience to create a positive organizational culture.

ABSTRACT

Background: Stenotrophomonas maltophilia bloodstream infections (BSI) are associated with considerable mortality in the hematologic malignancy population. Trimethoprim-sulfamethoxazole (TMP-SMX) is the treatment of choice, however, it is not routinely included in empiric treatment regimens both because of its adverse event profile and the relative rarity of S. maltophilia infections. We developed a risk score to predict hematologic malignancy patients at increased risk for S. maltophilia BSI to guide early (TMP-SMX) therapy. Methods: Patients ≥12 years of age admitted to five hospitals between 7/2016 and 12/2019 were included. Two separate risk scores were developed: (1) a “knowledge-driven” risk score based upon previously identified risk factors in the literature in addition to variables identified by regression analysis using the current cohort and (2) a risk score based upon automatic variable selection. For both scores, discrimination (ROC curves and C statistics) and calibration (Hosmer-Lemeshow goodness of fit test and graphical calibration plots) were assessed. Internal validation was assessed using leave-one-out cross-validation. Results: 337 unique patients were included; 21 (6.2%) had S. maltophilia BSI. The knowledge-driven risk score (acute leukemia, absolute neutrophil count category, mucositis, central line, and ≥3 days of carbapenem therapy) had superior performance (C-statistic=0.75; 0.71 after cross-validation) compared to the risk score utilizing automatic variable selection (C-statistic=0.63; 0.38 after cross-validation). Conclusions: A user-friendly risk score incorporating five variables easily accessible to clinicians performed moderately well to predict hematologic malignancy patients at increased risk for S. maltophilia BSI. External validation using a larger cohort is necessary to create a refined risk score before broad clinical application.

ABSTRACT

Objective: The Internalized Stigma of Mental Illness (ISMI) scale is widely used to examine internalized stigma among people with mental illness. However, an Indonesian version does not yet exist. We developed an Indonesian translation of the ISMI scale and assessed its psychometric properties. Method: We included 280 inpatients with mental illness diagnoses in 2 hospitals and a rehabilitation center. We followed the guidelines proposed by Sousa and Rojjanasrirat (2011) to translate the questionnaire. The reliability was evaluated by measuring the internal consistency (Cronbach’s alpha) and test-retest reliability. Test validity was measured through exploratory factor analysis (EFA) to examine the structure of the scale and confirmatory factor analysis (CFA) to determine the model fits. Results: The EFA yielded 5 factors with Cronbach’s alpha coefficients of .96 for the total scale and .95, .95, .93, .94, and .82 for the 5 subscales. The test-retest reliability indicated excellent results, demonstrated by the interclass correlation coefficient ranging between .76 and .92 for all ISMI scale items. The Kaiser-Meyer-Olkin test statistic was 0.95, and Bartlett’s test of sphericity value was significant. Conclusions and Implications for Practice: The CFA indicated that the ISMI scale has an acceptable model fit. The Indonesian version of the ISMI scale demonstrated good psychometric properties for measuring internalized stigma of psychiatric patients in Indonesia.

ABSTRACT

Joint physical custody (JPC), a parental care arrangement in which children live with each parent about equally after separation or divorce, is an increasingly common phenomenon in many countries. This is a major shift away from the standard of sole physical custody (SPC), in which children live primarily with one parent (usually their mother) after family dissolution. Although attention to JPC by social scientists is growing, and the effects of this arrangement on children’s well-being are the subject of highly ideological debates, there is currently little empirical evidence with statistical power on JPC. Using data from Family Models in Germany (FAMOD), a survey of postseparation families conducted in 2019, we estimated four linear regression models for children aged 2-14 in SPC and JPC families, with analytic samples of up to 1,161 cases. We investigated the association between physical custody arrangements after separation or divorce and four dimensions of children’s well-being: psychological, physical, social, and cognitive/educational. The bivariate results provided support for the hypothesis that children living in JPC families fare significantly better than children living in SPC families on all four dimensions of well-being. However, after controlling for a set of child, parent, and separation characteristics, as well as for the quality of family relationships, the differences between children from SPC and JPC families disappeared. Additional analyses revealed that the parent-child relationships fully mediated this association. In sum, the quality of family relationships accounted for the positive association between JPC and children’s well-being in this study. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

ABSTRACT

Depression has drawn increasing attention from the public around the world in recent years. Studies have shown that liver injury caused by chronic stress is relevant to depression and neurotransmitter changes. It is essential to clarify the relationship between neurotransmitter changes and hepatic gene expression in depression. In this study, we used the chronic unpredictable mild stress (CUMS) model combined with UHPLC-MS to explore the changes of neurotransmitters in serum and hippocampus and to decipher the differential gene expression in the liver by using the RNA-Seq combined with multivariate statistical analysis. Compared with the control group, the levels of neurotransmitters including 5-hydroxytryptamine (5-HT), acetylcholine, glutamate (Glu), and dopamine (DA) in the hippocampus and 5-HT, norepinephrine, γ-aminobutyric acid (GABA), and 5-hydroxyindoleacetic acid in serum were significantly changed in the CUMS rats. The results of liver transcriptomic analysis and correlation analysis showed that the Glu, DA, 5-HT, and GABA were impacted by 68 liver genes which were mainly enriched in three pathways including circadian rhythm, serotonergic synapse, and p53 signaling pathway. The expressive levels of clock genes and serotonergic synapse genes were validated by using q-PCR, and the diurnal rhythms of neurotransmitters were validated by in vivo hippocampus microdialysis. The CUMS stressors might cause phase advance of Glu and GABA by adjusting clock genes. The transcriptomic technique combined with correlation analysis and in vivo microdialysis could be used to discover comprehensive pathways of depression. It provides a new strategy for the rational assessment of the mechanism of disease.

ABSTRACT

When researchers choose to identify and exclude outliers from their data, should they do so across all the data, or within experimental conditions? A survey of recent papers published in the Journal of Experimental Psychology: General shows that both methods are widely used, and common data visualization techniques suggest that outliers should be excluded at the condition-level. However, I highlight in the present paper that removing outliers by condition runs against the logic of hypothesis testing, and that this practice leads to unacceptable increases in false-positive rates. I demonstrate that this conclusion holds true across a variety of statistical tests, exclusion criterion and cutoffs, sample sizes, and data types, and shows in simulated experiments and in a reanalysis of existing data that by-condition exclusions can result in false-positive rates as high as 43%. I finally demonstrate that by-condition exclusions are a specific case of a more general issue: Any outlier exclusion procedure that is not blind to the hypothesis that researchers want to test may result in inflated Type I errors. I conclude by offering best practices and recommendations for excluding outliers. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

ABSTRACT

BACKGROUND: Tobacco is the leading cause of preventable death, and over 200,000 women die each year of diseases caused by tobacco. Women with substance use disorders (SUDs) are disproportionately affected. Smoking prevalence among individuals enrolled in SUD treatment is 2-4 times higher than that of the general population, yet less than half of all treatment facilities offer tobacco treatment services. However, when individuals combine treatment, they have a greater likelihood of long-term abstinence from alcohol and other substances of use.

METHODS: A quality improvement project was undertaken to implement the U.S. Public Health Service guideline for tobacco cessation in a women’s residential substance use treatment facility. Tobacco users were advised on their health risk and recommended to cut down or quit. They were advised that help was available using nicotine replacement therapy, behavioral counseling, or both.

RESULTS: Upon admission, 67% of clients received brief advice to quit, and 30% participated in an intensive treatment aimed at reducing or eliminating cigarette use. At discharge, counseling participants (n = 21) smoked an average of nine cigarettes per day, reduced from 23, which was statistically significant.

IMPLICATIONS FOR PRACTICE: Interventions reduced cigarette smoking in a population at a high risk for adverse outcomes related to use. Results suggest that more clients are interested in tobacco treatment than previously estimated. Increased administrative, clinical, and pharmacy support can sustain and further assist clients with cessation efforts.

ABSTRACT

BACKGROUND: The strategy of isolated tricuspid valve surgery has undergone innovations in recent years. This study aimed to summarize our experience using an endoscopic approach to repeat isolated tricuspid valve surgery (RITS) after left-sided valve replacement (LSVR).

METHODS: From June 2013 to May 2019, 79 patients underwent endoscopic RITS after LSVR at our institution. Patients were divided into the tricuspid valvuloplasty (TVP) group (n = 49) and the tricuspid valve replacement (TVR) group (n = 30); perioperative outcomes and followup results were compared.

RESULTS: There were seven postoperative deaths (8.9%). In-hospital mortality was higher in the TVR group than in the TVP group, although this difference was not statistically significant (13.3% vs. 6.1%, P = 0.417). More patients experienced residual moderate-tosevere tricuspid regurgitation (TR) at discharge in the TVP group than in the TVR group (26.7% vs. 0%, P = 0.003). Five patients died from heart, and multiorgan failure during follow-up; the overall 3- and 5-year survival rates were 93.8% [95% confidence interval (CI): (87.1-99.9%)] and 85.3% (95% CI: 73.3-9.2%), respectively, and no significant differences were found between the two groups (P = 0.103). The overall rates of the 3- and 5-year freedom from severe recurrent TR were 93.2% (95% CI: 85.9-99.9%) and 89.0% (78.7-99.9%), respectively, and no significant difference was found between groups (P = 0.176).

CONCLUSIONS: Repeat isolated tricuspid valve surgery after left-sided valve replacement is associated with adverse perioperative outcomes. Endoscopic access offers an alternative approach for RITS after LSVR with acceptable results. TVP results in lower surgical mortality than TVR while carrying a higher risk of residual moderate-to-severe TR.

ABSTRACT

Since the 1970s, most births in the United States have been planned to occur in a hospital. However, a small percentage of Americans choose to give birth outside of a hospital. The number of out-of-hospital births has increased, with one in every 61 U.S. births (1.64%) occurring out of the hospital in 2018. Out-of-hospital (or community) birth can be planned or unplanned. Of those that are planned, most occur at home and are assisted by midwives. Patients who choose a planned community birth do so for multiple reasons. International observational studies that demonstrate comparable outcomes between planned out-of-hospital and planned hospital birth may not be generalizable to the United States. Most U.S. studies have found statistically significant increases in perinatal mortality and neonatal morbidity for home birth compared with hospital birth. Conversely, planned community birth is associated with decreased odds of obstetric interventions, including cesarean delivery. Perinatal outcomes for community birth may be improved with appropriate selection of low-risk, vertex, singleton, term pregnancies in patients who have not had a previous cesarean delivery. A qualified, licensed maternal and newborn health professional who is integrated into a maternity health care system should attend all planned community births. Family physicians are uniquely poised to provide counseling to patients and their families about the risks and benefits associated with community birth, and they may be the first physicians to evaluate and treat newborns delivered outside of a hospital.
