Pregnancy complicated by non-Hodgkin's lymphoma (NHL) has rarely been reported. Few reports in the medical liter-ature focus on pregnancy complicated by both NHL and hepatitis B virus infection. A multidisciplinary discussion is conducted concern-ing the treatment of the patient. The standard treatment procedure for pregnancy complicated by non-Hodgkin's lymphoma and the cre-ation of a multidisciplinary team were also discussed.

Objective:To explore the epidemiological factors of patients with OHCA who did not attempt CPR, and analyze the reasons and clinical features of non resuscitation.Methods:Data from OHCA patients who did not undergo CPR were collected from January 2020 to December 2020 at Beijing Emergency Medical Center. The registration form was designed according to the Utstein model, and the data were analyzed retrospectively by the chi-square test.Results:A total of 5 977 patients were enrolled and divided into two groups according to age: 2 349 patients aged ≤ 80 years old and 3 628 patients aged ≥ 81 years old. Compared with the younger group, the proportion of patients in the older group who did not undergo CPR due to disease (97.0%) and family desertion (99.4%) were higher, and the difference was statistically significant (both P<0.01). Conclusions:Elderly people over 80 years old with underlying diseases have a high probability of developing OHCA at home. Most of the witnesses at the scene were family members and could not implement CPR in time. After the emergency personnel arrived at the scene, they found that the patient had been in cardiac arrest for too long and had apparently died. Family members would choose to give up treatment.

Objective:To analyze the clinical characteristics of patients with cardiac arrest caused by poisoning, explore the differences in the corresponding emergency measures and emergency effects under different causes of poisoning, and improve the success rate of out-of-hospital cardiac arrest rescue.Methods:All out-of-hospital toxic cardiac arrest patients admitted to Beijing Emergency Medical Center from January 2021 to December 2021 were retrospectively included.Results:A total of 38 patients with a median age of 43 years, including 26(68.4%) were male. There were 20 cases of acute alcoholism (52.6%), and 9 (23.7%) cases of carbon monoxide and drug poisoning respectively. In 38 cases, only 2 cases achieved return of spontaneous circulation, and no cases survived more than 24 hours.Conclusions:Poisoning induced cardiac arrest is one of the non-cardiac causes of out-of-hospital cardiac arrest, responsible for 1.7%. Alcoholism is the main poisoning cause of noncardiac out-of-hospital cardiac arrest in Beijing, prevent the poisoning and quickly identify the cause of the poisoning and give the correct rescue measures is very important for cardiac arrest.
