[Ultrasonic and pathological comparative analysis of different subtypes of breast encapsulated papillary carcinoma].

Objective: To investigate the clinicopathological and ultrasonic characteristics of patients with breast encapsulated papillary carcinoma (EPC) and the comparative analysis of different subtypes. Methods: A total of 57 patients with pathological diagnosis of breast EPC in the First Affiliated Hospital of Nanjing Medical University from September 2014 to August 2020 were retrospectively collected. Based on pathological diagnosis, patients were divided into 3 subtypes, and their clinical, pathological and ultrasonic manifestations were compared and analyzed. Results: Among the enrolled patients, there were 2 males and 55 females, aged 41-88 (63±11) years. The lesion diameter of EPC was 7.0-7.5 (2.9±1.9) cm. There were 16 cases of simple EPC, 9 cases of EPC with ductal carcinoma in situ (DCIS), and 32 cases of EPC with infiltration. The molecular classification was mainly luminal (55/57, 96.6%), of which 38 cases were Luminal A type and 17 cases were Luminal B type. The majority ultrasound images of EPC showed nodules with size greater than 2 cm (68.4%), regular morphology (64.9%), edge finishing (54.4%), no burr forming angles (82.5%), and no calcification (93%). There were differences between different subtypes. The simple EPC was closer to the nipple than the EPC with infiltration, with regular shape and smooth edge (P<0.05). Compared with the EPC with DCIS, the EPC with infiltration had richer blood flow and was farther away from the nipple (P<0.05). There was no significant difference between the simple EPC and the EPC with DCIS (P>0.05). Conclusion: The simple EPC often showed benign signs on ultrasound, such as regular morphology, smooth edge, and cystic-solid internal structure. If the distance between the lesion and the nipple was greater than 3 cm, the shape was irregular, and the edge was blurred, the possibility of EPC with infiltration was high. Multi-modality image fusion was helpful for accurate diagnosis and treatment of EPC.

Prevalence of comorbid major depressive disorder in Type 2 diabetes: a meta-analysis of comparative and epidemiological studies.

AIMS: To examine the average point prevalence of major depressive disorder in people with Type 2 diabetes and its associated factors in a comprehensive meta-analysis. METHODS: Two researchers independently conducted a systematic literature search of PubMed, EMBASE, PsycINFO and Cochrane databases. Studies reporting the prevalence of major depressive disorder in people with Type 2 diabetes were identified and analysed using a random-effects model. RESULTS: A total of 26 studies meeting the inclusion criteria were included in the study. The point prevalence of major depressive disorder was 14.5% (95% CI 7.9-25.3; I²=99.65). People with Type 2 diabetes were more likely to have major depressive disorder compared with the general population (odds ratio 1.73, 95% CI 1.38-2.16). Subgroup and meta-regression analyses showed that study site, study type, diagnostic criteria and age significantly moderated the prevalence of major depressive disorder. CONCLUSIONS: In this meta-analysis, the average point prevalence of major depressive disorder in people with Type 2 diabetes was high. Routine screening and more effective interventions should be implemented for this population.

[Effect of influenza and 23-valent pneumococcal polysaccharide vaccinations on elderly with chronic obstructive pulmonary diseases: a community-based intervention study].

Objective: To explore the effect of influenza and 23 valent pneumococcal polysaccharide pneumococcal vaccinations on symptom-improvement among elderly with chronic obstructive pulmonary diseases (COPD). Methods: Data was gathered from 4 communities in 3 National Demonstration Areas set for comprehensive prevention and control of chronic non- communicable diseases in Chongqing city and Ningbo city respectively, from November 2013 to October 2014. The communities were selected by cluster sampling and divided into 4 groups: (1) injected influenza vaccines; (2) injected with pneumococcal vaccines; (3) received both of the two vaccines; (4) the control group that without any intervention measures. All the subjects aged from 60 to 75 were selected to fill in demographic information questionnaire and receive (COPD assessment test, CAT) scores twice, before intervention and 1 year after the vaccination. SAS 9.4 software was used to analyze the change of symptoms and CAT scores before and after the intervention program and comparing the improvement on symptoms among the elderly people under study. Results: A total of 1 244 subjects with nearly same baseline conditions after the propensity score matching, were involved in this study. CAT scores appeared as Median=21 (IQR: 17-26) at baseline. The CAT scores appeared as Median=18 (IQR: 14-24), decreasing in all the 3 vaccinated groups, one year after the intervention program (influenza vaccines, matching t test, t=-6.531, P=0.403; pneumococcal vaccines, Wilcoxon test, H=-9 623, P<0.001; combined vaccine vaccines, matching t test, t=-10.803, P<0.001). However, in the control group, no obvious change was observed (Wilcoxon H=1 167, P=0.403). Proportions of impacts at high or very high levels all decreased in the 3 intervention groups, while little change was observed in the control group. Outcomes from the Factorial analysis suggested that influenza vaccination could improve the general conditions and symptoms including cough, chest tightness, dyspnea, physical activities, and stamina. Pneumococcal vaccination appeared more effective on all of symptoms and indicators. Conclusion: Pneumococcal and influenza vaccination seemed helpful for elderly people suffering COPD to improve the general health condition.
