Identifying severe community-acquired pneumonia using radiomics and clinical data: a machine learning approach.

Evaluating Community-Acquired Pneumonia (CAP) is crucial for determining appropriate treatment methods. In this study, we established a machine learning model using radiomics and clinical features to rapidly and accurately identify Severe Community-Acquired Pneumonia (SCAP). A total of 174 CAP patients were included in the study, with 64 cases classified as SCAP.

Paired organoids from primary gastric cancer and lymphatic metastasis are useful for personalized medicine.

Background: Organoids are approved by the US FDA as an alternative to animal experiments to guide drug development and for sensitivity screening. Stable organoids models of gastric cancer are desirable for personalized medicine and drug screening.

Methods: Tumor tissues from a primary cancer of the stomach and metastatic cancer of the lymph node were collected for 3D culture.

Progress of research on the relationship between efferocytosis and tumor.

Tumors are genetic changes that develop in an organism as a result of many internal and external causes. They affect the biological behavior of cells, cause them to grow independently, and give rise to new, perpetually proliferating organisms. Recent research has supported the critical function of tumor-associated macrophages in the development, progression, and metastasis of tumors through efferocytosis.

The efficacy of neoadjuvant chemotherapy is different for type 4 and large type 3 gastric cancer.

Background: In the JCOG0501 study, neoadjuvant chemotherapy (NAC) failed to demonstrate survival benefits for type 4 and large type 3 gastric cancer (GC). The prognosis of these patients is still poor. We conducted this study to explore the value of NAC with non-SP regimens for type 4 and large type 3 ​GC in the Chinese population.

Sintilimab combined neoadjuvant intraperitoneal and systemic chemotherapy in gastric cancer with peritoneal metastasis.

Intraperitoneal chemotherapy combined with systemic chemotherapy is one of the therapeutic modalities currently used for the treatment of gastric cancer patients with peritoneal metastasis. This study was designed to evaluate the efficacy and safety of sintilimab plus S-1 combined intraperitoneal and intravenous paclitaxel. This is an open-label, single-center, phase II study including 36 gastric adenocarcinoma patients with peritoneal metastases diagnosed by laparoscopy.

Efficacy and Safety of Conversion Therapy by Intraperitoneal and Intravenous Paclitaxel Plus Oral S-1 in Gastric Cancer Patients With Peritoneal Metastasis: A Prospective Phase II Study.

Background: Neoadjuvant intraperitoneal and systemic chemotherapy (NIPS) has shown promising results in gastric cancer (GC) with peritoneal metastasis. However, clinical practice experience of NIPS is still lacking in China. In this study, we investigate the efficacy and safety of NIPS in Chinese patients.

A phase III trial of neoadjuvant intraperitoneal and systemic chemotherapy for gastric cancer with peritoneal metastasis.

Although recent advances in systemic chemotherapy have improved the clinical outcomes of gastric cancer patients with peritoneal metastasis, the peritoneum still represents a common site of treatment failure and disease recurrence. Neoadjuvant intraperitoneal-systemic chemotherapy has been acknowledged as a more aggressive treatment for gastric cancer patients with peritoneal metastasis. In this multicenter phase III randomized controlled trial, 238 patients will be randomly separated into two groups in a 2:1 ratio after laparoscopic exploration.

Oxaliplatin plus S-1 with intraperitoneal paclitaxel for the treatment of Chinese advanced gastric cancer with peritoneal metastases.

Background: In this study, we tried to access the efficacy and safety of oxaliplatin plus S-1 with intraperitoneal paclitaxel (PTX) for the treatment of Chinese advanced gastric cancer with peritoneal metastases.

Patients And Methods: Thirty patients diagnosed with advanced gastric cancer underwent laparoscopic exploration and were enrolled when macroscopic disseminated metastases (P1) were confirmed. PTX was diluted in 1 l of normal saline and IP administered through peritoneal port at an initial dose of 40 mg/m over 1 h on day1,8, respectively.

Is D2 Lymphadenectomy Alone Suitable for Gastric Cancer With Bulky N2 and/or Para-Aortic Lymph Node Metastases After Preoperative Chemotherapy?

Background: For gastric cancer (GC) with extensive lymph node metastasis (bulky N2 and/or para-aortic lymph node metastases), there is no standard therapy worldwide. In Japan, preoperative chemotherapy (PCT) followed by D2 gastrectomy plus para-aortic lymph node dissection (PAND) is considered the standard treatment for these patients. However, in China, the standard operation for GC patients with only bulky N2 metastases was D2 gastrectomy.

Neoadjuvant Chemotherapy Direct Surgery for Locally Advanced Gastric Cancer With Serosal Invasion (cT4NxM0): A Propensity Score-Matched Analysis.

Background: For locally advanced gastric cancer (LAGC) with serosal invasion (cT4NxM0), adjuvant chemotherapy (AC) after D2 gastrectomy is the standard therapy in Asia. However, perioperative chemotherapy (PCT) combined with D2 gastrectomy is mostly suggested in Europe and America. As a part of PCT, the value of neoadjuvant chemotherapy (NAC) is unclear.

Cost Effectiveness of Different Initial Antimicrobial Regimens for Elderly Community-Acquired Pneumonia Patients in General Ward.

Purpose: The cost-effectiveness of different guideline-concordant antimicrobial regimens for elderly patients with community-acquired pneumonia (CAP) was rarely discussed. This study attempts to explore the most appropriate cost-effectiveness of guideline-concordant antimicrobial regimen for elderly patients with CAP in general wards.

Patients And Methods: This was a multicenter, retrospective, 4:2:1 matched study enrolling 511 elderly patients with CAP hospitalized in general wards.

A randomized controlled trial to evaluate omentum-preserving gastrectomy for patients with T1-T3 gastric cancer.

Although complete omentectomy is traditionally performed in patients with gastric cancer as part of radical gastrectomy to ensure the elimination of micrometastases, the prognostic value of omentectomy during gastrectomy remains unclear. Retrospective studies have shown that the incidence of metastases in the greater omentum is very low in T1-T3 gastric cancer. Thus radical gastrectomy with D2 lymphadenectomy and preservation of the greater omentum may be a proper curative treatment for gastric cancer patients with T1-T3 tumors.

Prediction Model of Tumor Regression Grade for Advanced Gastric Cancer After Preoperative Chemotherapy.

Background: Preoperative chemotherapy (PCT) has been considered an important treatment for advanced gastric cancer (AGC). The tumor regression grade (TRG) system is an effective tool for the assessment of patient responses to PCT. Pathological complete response (TRG = 0) of the primary tumor is an excellent predictor of better prognosis.

Prediction model of objective response after neoadjuvant chemotherapy in patients with locally advanced gastric cancer.

Background: Neoadjuvant chemotherapy (NAC) plays an important role in the therapeutic strategy of locally advanced gastric cancer (LAGC). However, the response of LAGC after NAC varies among different patients. The objective response after NAC has proven to be an excellent indicator for benefiting from NAC, yet effective predictors of objective response are still lacking.

Disease burden and prognostic factors for clinical failure in elderly community acquired pneumonia patients.

Background: The study was to evaluate initial antimicrobial regimen and clinical outcomes and to explore risk factors for clinical failure (CF) in elderly patients with community-acquired pneumonia (CAP).

Methods: 3011 hospitalized elderly patients were enrolled from 13 national teaching hospitals between January 1, 2014 and December 31, 2014 initiated by the CAP-China network. Risk factors for CF were screened by multivariable logistic regression analysis.

Prophylactic HIPEC with radical D2 gastrectomy improves survival and peritoneal recurrence rates for locally advanced gastric cancer: personal experience from a randomized case control study.

Background: To investigate the implications of prophylactic intraoperative Hyperthermic Intraperitoneal Chemotherapy (HIPEC) with D2 radical gastrectomy for locally advanced Gastric Cancer (AGC) in a randomized case control study.

Method: Eighty consecutive patients with locally AGC were randomly separated into 2 groups: HIPEC group (Curative Resection + intraoperative HIPEC with cisplatin 50 mg/m at 42.0 ± 1.

[Analysis of clinical features and prognostic factors on reoperation patients with postoperative recurrence or metastasis of gastrointestinal stromal tumor].

Objective: To investigate the clinical characteristics and prognostic factors of reoperation patients with postoperative recurrence or metastasis of gastrointestinal stromal tumor (GIST).

Methods: A retrospective case-control study was performed on the clinical data of 31 patients with GIST who had recurrence or metastasis after the first surgery and underwent one or more operations again from February 2003 to January 2016 at Ruijin Hospital, Shanghai Jiaotong University School of Medicine. The clinical characteristics of these patients were analyzed.

Effects of age, comorbidity and adherence to current antimicrobial guidelines on mortality in hospitalized elderly patients with community-acquired pneumonia.

Background: Limited information exists on the clinical characteristics predictive of mortality in patients aged ≥65 years in many countries. The impact of adherence to current antimicrobial guidelines on the mortality of hospitalized elderly patients with community-acquired pneumonia (CAP) has never been assessed.

Methods: A total of 3131 patients aged ≥65 years were enrolled from a multi-center, retrospective, observational study initiated by the CAP-China network.

Disease characteristics and management of hospitalised adolescents and adults with community-acquired pneumonia in China: a retrospective multicentre survey.

Objectives: To describe the clinical characteristics and management of patients hospitalised with community-acquired pneumonia (CAP) in China.

Design: This was a multicentre, retrospective, observational study.

Setting: 13 teaching hospitals in northern, central and southern China from 1 January 2014 to 31 December 2014 PARTICIPANTS: Information on hospitalised patients aged ≥14 years with radiographically confirmed pneumonia with illness onset in the community was collected using standard case report forms.

A critical analysis of the cytoreductive surgery with hyperthermic intraperitoneal chemotherapy combo in the clinical management of advanced gastric cancer: an effective multimodality approach with scope for improvement.

Peritoneal carcinomatosis (PC) is manifested in up to 40% of gastric cancer (GC) patients, after which their 5-year survival drops to less than 5%. The currently most acceptable treatment option for advanced GC (AGC) is systemic chemo and radio therapies with however generally very unsatisfying results and this led to a resurgence of interest in regional therapies like cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Small trials have indicated an association with prolonged survival when applying this technique to AGC manifesting with PC.
