This study aims to explore the prognostic variables for elderly papillary thyroid microcarcinoma (PTMC) patients as well as create a nomogram that could predict the occurrence of cervical lymph node metastasis (CLNM) on the basis of a large population database with high quality. A total of 5165 PTMC patients from Surveillance, Epidemiology, and End Results database database were enrolled in the study. In the meantime, we retrospectively collected 205 PTMC patients who underwent thyroidectomy in our medical center as an external control to test the accuracy of the model. ⋯ The calibration curves showed perfect agreement between nomogram predictions and actual observations. Elderly PTMC patients who received a surgical approach without radiotherapy showed survival advantage than those with other treatment strategies. Moreover, a nomogram model was established to predict the risk of CLNM, which will help clinicians in making treatment decisions.

To explore the risk factors of lung metastasis in patients after laparoscopic radical hysterectomy (LRH) of cervical cancer (CC). The clinical data of CC patients with clinical stage of IA1-IIA2 diagnosed in our hospital from April 2007 to October 2015 were collected. According to the situation of metastasis, the patients were divided into lung metastasis (n = 73) and non-lung metastasis group (n = 2076). ⋯ However, it was not related to age, clinical stage, tumor growth pattern, tumor differentiation, and para-aortic lymph node metastasis (P > .05). Logistic regression analysis revealed non-squamous cell carcinoma (P = .022), tumor diameter ≥4 cm (P = .008), interstitial invasion depth >2/3 (P = .003), PLNM (P = .007), and tumor uterine invasion (P = .037) is an independent risk factor for lung metastasis after LRH of CC. Non-squamous cell carcinoma, tumor diameter ≥4 cm, tumor interstitial invasion depth >2/3, PLNM, and tumor uterine invasion are independent risk factors for lung metastasis after LRH of CC.

Until recently, the survival rate in patients with Philadelphia-positive acute lymphoblastic leukemia (Ph+ ALL) was approximately 30%. Tyrosine kinase inhibitors (TKIs), which are a new class of drugs that target BCR-ABL fusion protein, have shown to be effective in treating Ph+ ALL in adults. However, the resistance mechanisms that promote the disease recurrence have altered the initial success of these revolutionary agents. ⋯ Multidrug-resistant mutations within the BCR-ABL1 kinase domain are an emerging clinical problem for patients receiving sequential TKIs therapy. Acquisition of E255K/V-inclusive mutations is usually associated with ponatinib resistance, thus it is necessary to screen out new real pan-inhibitor compounds for all BCR/ABL mutations and figure out the potential efficacy of asciminib-based drug combinations in the future.

To provide valuable experience for other countries currently fighting the COVID-19 pandemic by systematically analyzing the effects of control policies on coping with COVID-19 in Guangdong Province of China. Integrating qualitative and quantitative methods to systematically analyze the effects of control policies on fighting COVID-19 with official data in Guangdong Province. Between January 19, 2020 and February 26, 2020, Guangdong Province issued 6 critical control policies to cope with COVID-19 and achieved effects in the following 3-phase. 1. ⋯ In the first phase, the first 4 control policies showed initial effects on COVID-19 epidemic control. In the second phase, the last 2 control policies greatly contributed to containing the COVID-19 epidemic. In the third phase, the 6 control policies completely overcame the COVID-19 in Guangdong Province, China.

Case Reports
Acute myeloid leukaemia presenting with ecthyma gangrenosum as the first manifestation: A case report.
Ecthyma gangrenosum (EG) is an uncommon cutaneous infection usually associated with Pseudomonas aeruginosa bacteremia in immunocompromised patients, particularly those with underlying malignant diseases. Despite its rarity, especially in immunocompetent or nondiagnosed immunodeficiency patients, EG can present as the first manifestation of an underlying immunosuppression. ⋯ It should be kept in mind that EG is an important cutaneous infection that is typically associated with P aeruginosa bacteremia and the presence of underlying immunodeficiency, such as acute leukaemia.
