Background
There are growing calls to tailor counselling practices for adolescent males, a population reluctant to engage in psychological treatment despite concerning rates of mental illness. The objective of this systematic review (PROSPERO: CRD4202125547) was to collate and synthesise recommendations for individual counselling with adolescent males (12–18 years).Method
The databases Psychology and Behavioural Science Collection, PsycArticles, PsycINFO, Academic Search Complete, EBSCO eBook Collection, Wiley Science Collection, Taylor and Francis Collection and ProQuest One Academic were searched for articles published between 1995 and November 2021. The quality of evidence was assessed using the JBI critical appraisal checklists, and thematic analysis was employed to synthesise findings across the literature.Results
A total of 1625 texts were identified, of which 16 met the inclusion criteria. Generated themes included (a) therapist knowledge of masculinity, gender socialisation, and male-relational styles; (b) necessity of therapists to address masculinity in the therapeutic space; and (c) customising engagement and treatment practices to appeal to adolescent males.Conclusions
The themes highlighted the unique developmental, and sociocultural considerations practitioners should be aware of when working with young men. Through a multicultural counselling competency framework, masculinity and adolescent male identity are expressions of diverse sociocultural identities that psychological assessment and intervention should ideally be tailored to suit. The findings of the review suggest that empirical research focusing on the experiences of adolescent males receiving psychological treatment is sparse. Further research is needed to inform the development of practicable, gender-sensitive adaptions to counselling practice for young men. 相似文献932.

Backgrounds: Percutaneous ultrasound (US) and endoscopic ultrasound (EUS)-guided pancreatic biopsies are widely accepted in the diagnosis of pancreatic diseases. Studies comparing the diagnostic performance of US- and EUS-guided pancreatic biopsies are lacking. This study aimed to evaluate and compare the diagnostic yields of US- and EUS-guided pancreatic biopsies and identify the risk factors for inconclusive biopsies.
Methods: Of the 1074 solid pancreatic lesions diagnosed from January 2017 to February 2021 in our center, 275 underwent EUS-guided fine needle aspiration (EUS-FNA), and 799 underwent US-guided core needle biopsy (US-CNB/FNA). The outcomes were inconclusive pathological biopsy, diagnostic accuracy and the need for repeat biopsy. All of the included factors and diagnostic performances of both US-CNB/FNA and EUS-FNA were compared, and the independent predictors for the study outcomes were identified.
Results: The diagnostic accuracy was 89.8% for EUS-FNA and 95.2% for US-CNB/FNA ( P = 0.001). Biopsy under EUS guidance [odds ratio (OR) = 1.808, 95% confidence interval (CI): 1.083-3.019; P = 0.024], lesion size < 2 cm (OR = 2.069, 95% CI: 1.145-3.737; P = 0.016), hypoechoic appearance (OR = 0.274, 95% CI: 0.097-0.775; P = 0.015) and non-pancreatic ductal adenocarcinoma carcinoma (PDAC) diagnosis (OR = 2.637, 95% CI: 1.563-4.449; P < 0.001) were identified as factors associated with inconclusive pathological biopsy. Hypoechoic appearance (OR = 0.236, 95% CI: 0.064-0.869; P = 0.030), lesions in the uncinate process of the pancreas (OR = 3.506, 95% CI: 1.831-6.713; P < 0.001) and non-PDAC diagnosis (OR = 2.622, 95% CI: 1.278-5.377; P = 0.009) were independent predictors for repeat biopsy. Biopsy under EUS guidance (OR = 2.024, 95% CI: 1.195-3.429; P = 0.009), lesions in the uncinate process of the pancreas (OR = 1.776, 95% CI: 1.014-3.108; P = 0.044) and hypoechoic appearance (OR = 0.127, 95% CI: 0.047-0.347; P < 0.001) were associated with diagnostic accuracy.
Conclusions: Both percutaneous US- and EUS-guided biopsies of solid pancreatic lesions are safe and effective; though the diagnostic accuracy of EUS-FNA is inferior to US-CNB/FNA. A tailored pancreatic biopsy should be considered a part of the management algorithm for the diagnosis of solid pancreatic disease. 相似文献
