Dental professionals perceived the management of drug users as demanding due to dental fear, difficulties in coping with appointments, poor compliance to preventive measures, and disagreement between dental treatment defined as necessary and drug users' expectations.

Measurement of serum human epidermal growth factor receptor-2 (HER-2/neu) levels might play an essential role as a diagnostic/screening marker for the early selection of therapeutic approaches and predict prognosis in breast cancer patients. We aimed to undertake a systematic review and meta-analysis focusing on the diagnostic/screening value of serum HER-2 levels in comparison to routine methods.

We performed a systematic search via PubMed, Scopus, Cochrane-Library, and Web of Science databases for human diagnostic studies reporting the levels of serum HER-2 in breast cancer patients, which was confirmed using the histopathological examination. Meta-analyses were carried out for sensitivity, specificity, accuracy, area under the ROC curve (AUC), positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (PLR), and negative likelihood ratio (NLR).

Fourteen studies entered into this investigation. The meta-analysis indicated the low sensitivity for serum HER2 levels (Senst for initial negative screening test results, especially in low-income regions due to its cost-effectiveness and ease of implementation.
Primary pure angiosarcoma of the testis is an exceptionally rare testicular malignancy, which is poorly understood. We present the fifth and youngest case in the current medical literature. Additionally, all cases of angiosarcoma of the testicle, both occurring with associated germ cell tumour and without, were compared in an extended tabular format.

A 56-year old man presented with unilateral scrotal pain, swelling and erythema. Ultrasonography revealed two testicular lesions with a high suspicion of malignancy but serum tumour markers were negative. A radical orchidectomy was performed with clear surgical margins. Diagnosis of primary pure angiosarcoma of the testis was confirmed on subsequent histopathology.

Primary pure angiosarcoma is a rare testicular neoplasm. We present the fifth case in the literature. Clinical and radiological features are non-specific. The diagnosis is purely histological, with the pathologist choosing immunohistochemistry based on abnormal morphology. Local invasiveness is viosarcoma arising in the context of a testicular germ cell tumour. While extra-gonadal angiosarcomas are associated with high rates of local recurrence following resection, in all cases of testicular angiosarcoma there were no local recurrences following radical orchidectomy. Surgical resection remains the most effective treatment for both subtypes of testicular angiosarcoma.
Antepartum activity restriction (AAR) is a common recommendation given to women at risk for preterm delivery. However, such treatment has been shown to cause heavy emotional burdens on the women receiving it since it requires them to face many challenges derived from the intervention. Nevertheless, current existing scales lack effective items that can reflect the distress of these women. The aim of this study was to develop a reliable instrument to assess the distress of women experiencing AAR.

The Prenatal Activity Restriction Stress Questionnaire (PARSQ) was developed according to comprehensive literature review, women's interviews, and existing pregnancy-special stress scales from August 2016 to July 2017 in southern Taiwan. Six experts evaluated its content validity; the Rasch rating scale model (RSM) was used to examine its item-fit, dimensionality, and reliability with 200 women with AAR experience. this website Furthermore, the concurrent validity was assessed through computing the correlation of AAR women's scmen with AAR.
Understanding the distress of women undergoing AAR is necessary for developing appropriate prenatal care to assist women in coping with their situation to alleviate their emotional burdens. The developed PARSQ with satisfied psychometric properties can be an informative instrument for clinicians/researchers to assess the specific stress of pregnant women with AAR.
Lung adenocarcinoma (LUAD) remains a crucial factor endangering human health. Gene-based clinical predictions could be of great help for cancer intervention strategies. Here, we tried to build a gene-based survival score (SS) for LUAD via analyzing multiple transcriptional datasets.

We first acquired differentially expressed genes between tumors and normal tissues from intersections of four LUAD datasets. Next, survival-related genes were preliminarily unscrambled by univariate Cox regression and further filtrated by LASSO regression. Then, we applied PCA to establish a comprehensive SS based on survival-related genes. Subsequently, we applied four independent LUAD datasets to evaluate prognostic prediction of SS. Moreover, we explored associations between SS and clinicopathological features. Furthermore, we assessed independent predictive value of SS by multivariate Cox analysis and then built prognostic models based on clinical stage and SS. Finally, we performed pathway enrichments analysis and investigated immune checkpoints expression underlying SS in four datasets.

We established a 13 gene-based SS, which could precisely predict OS and PFS of LUAD. Close relations were elicited between SS and canonical malignant indictors. Furthermore, SS could serve as an independent risk factor for OS and PFS. Besides, the predictive efficacies of prognostic models were also reasonable (C-indexes OS, 0.7; PFS, 0.7). Finally, we demonstrated enhanced cell proliferation and immune escape might account for high clinical risk of SS.

We built a 13 gene-based SS for prognostic prediction of LUAD, which exhibited wide applicability and could contribute to LUAD management.
