Emamectin Benzoate, a potent pesticide extensively used in agriculture, has raised concerns due to its potential for severe poisoning. While its safety in mammals is attributed to limited blood-brain barrier penetration and reduced affinity for specific channels, Emamectin Benzoate Poisoning can unexpectedly manifest with severe symptoms. Predominantly resulting from intentional ingestion, clinical presentations involve central nervous system depression, respiratory distress, gastrointestinal symptoms, and sore throat.

Introduction/background: Positive surgical margins (PSMs) after radical prostatectomy (RP) can increase the risk of biochemical recurrence in prostate cancer (PCa) patients. However, the prediction of the likelihood of PSMs in patients undergoing similar surgical procedures remains a challenge. We aim to develop a predictive model for PSMs in patients undergoing non-nerve-sparing RP.

Patients with advanced renal cancer (RCC) often have limited success with systemic therapy due to tumor heterogeneity. However, stereotactic ablative radiotherapy (SABR) has been shown to have a beneficial therapeutic effect for oligometastatic disease when used early. Despite this, current guidelines recommend the use of tyrosine kinase inhibitors (TKIs) as the first-line therapeutic agent for patients with recurrent or metastatic kidney cancer.

Background: Stereotactic ablative body radiotherapy (SABR) is one of the treatment options for oligometastatic renal cell carcinoma (RCC) but is limited by a lack of data to evaluate high-dose SABR to all/multiple sites.

Objective: This study retrospectively investigated the efficacy and prognostic factors of high-dose SABR for oligometastatic RCC patients.

Design, Setting, And Participants: Patients with oligometastatic RCC on systemic therapy were retrospectively collected.

This work proposed a modified plasma induced charging (PID) detector to widen the detection range, for monitoring the possible plasma damage across a wafer during advanced CMOS BEOL processes. New antenna designs for plasma induced damage patterns with extended capacitors are investigated. By adapting the novel PID detectors, the maximum charging levels of the detectors have been enhanced.

Habits such as smoking and alcohol drinking and existing esophageal malfunction are considered the main risk factors for esophageal carcinogenesis. Caustic ingestion of acidic or alkaline agents or strong irritants can induce severe esophageal corrosive injury and increase esophageal cancer risk. We studied the relationship between esophageal carcinoma and acute detergent or pesticide poisoning by using nationwide health insurance data.

Background: In Asia and some other regions of the world, incense burning is an important folk and cultural activity. However, this ritual can cause health impacts, such as chronic respiratory diseases and neoplasms. Herein, we describe a family with lead poisoning possibly related to the frequent use of incense sticks at home.

Objective: Previous research has demonstrated that patients with a history of organophosphate poisoning tend to have a higher risk of neurological disorder. However, research on the rate of seizure development in patients after organophosphate poisoning is lacking. This study examined whether individuals with organophosphate poisoning have an increased risk of seizures through several years of follow-up.

We aimed to investigate the prognostic value of chromogranin A (CgA) in castration-resistant prostate cancer (CRPC). We conducted a systematic literature search of PubMed, Web of Science, and EMBASE for citations published prior to September 2017 that described CgA and CRPC and performed a standard meta-analysis on survival outcomes. Our meta-analysis included eight eligible studies with 686 patients.

Introduction: Hematuria is the most common symptom of urothelial carcinomas (UC) but is often idiopathic. Cystoscopy is expensive which involves considerable patient discomfort, and conventional urine cytology for noninvasive UC detection and disease monitoring suffers from poor sensitivity. We aim to evaluate the performance of genes selected from a previous study in detecting UC, especially among patients with gross hematuria, as well as upper tract urothelial carcinoma (UTUC) and bladder carcinoma separately, in voided urine samples.

Background: To evaluate the prognostic significance of the novel index combining preoperative hemoglobin and albumin levels and lymphocyte and platelet counts (HALP) in renal cell carcinoma (RCC) patients.

Methods: We enrolled 1360 patients who underwent nephrectomy in our institution from 2001 to 2010. The cutoff values for HALP, neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio were defined by using X-tile software.

We designed a population-based retrospective cohort study to investigate the association between the event of alcohol intoxication and the risk of pyogenic liver abscess. The present study enrolled 245,076 patients with a history of alcohol intoxication from 2000 to 2010 and matched each of them with four comparison patients, with similar mean age and sex ratios. We determined the cumulative incidences and adjusted hazard ratios (aHRs) of liver abscess.

Objectives: To evaluate the prognosis of non-metastatic T3a renal cell carcinoma (RCC) with partial nephrectomy (PN).

Patients And Methods: We retrospectively evaluated 125 patients with non-metastatic T3a RCC. Patients undergoing PN and radical nephrectomy (RN) were strictly matched by clinic-pathologic characteristics.

Introduction: We compared the prognostic significance of inflammatory and nutritional scores, including the prognostic nutritional index (PNI), neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and lymphocyte-to-monocyte ratio in patients with renal cell carcinoma (RCC) undergoing nephrectomy.

Patients And Methods: We retrospectively analyzed the data from 1360 patients with RCC undergoing nephrectomy from 2001 to 2010. The PNI was calculated as the serum albumin level (g/L) + 5 × lymphocyte count (10/L).

Purpose: To validate plasma fibrinogen and serum cholesterol levels as prognostic factors for patients with renal cell carcinoma (RCC) and to explore the prognostic value of their combination.

Patients And Methods: Medical data for 1360 RCC patients after nephrectomy were collected. X-tile software was used to determine the cutoff values.

Objective: To investigate the factors that may predict the effectiveness of metastatic castration resistant prostate cancer (mCRPC) patients who received docetaxel plus prednisone treatment.

Methods: We retrospectively collected the clinical data of mCRPC patients who has received docetaxel chemotherapy in Peking University First Hospital between February 2010 and March 2015, and the clinical factors were analyzed using univariate analysis.

Results: A total of 60 cases of patients were treated, of whom 33 with complete clinical data were analyzed.

Objective: To study the characteristics of histopathologic features of small renal carcinoma.

Methods: This retrospective study collected the data of renal cell carcinoma from the patients who underwent surgery from January 2002 to June 2012. They were all preoperatively diagnosed as renal cancer by CT scan, and pathologically diagnosed as renal cell carcinoma after surgery with the diameter ≤ 4 cm.

Purpose: To evaluate the prevalence of baseline chronic kidney disease (CKD) in a large cohort of patients with renal masses in a single Chinese institution. Estimated glomerular filtration rate (eGFR) and CKD stage are more clinically relevant to predict the risk of morbidity and mortality in patients after nephrectomy. But, sCr reflects renal function poorly.

Ruptured celiac artery aneurysm is a rare cause for epigastric pain and is usually detected incidentally. Atypical presentation with postemetic epigastralgia and pleural effusion usually leads physicians to make the diagnosis of Boerhaave syndrome. Herein, we report a 32-year-old woman who was diagnosed with Boerhaave syndrome initially after presenting with acute postemetic epigastralgia and predominant left side pleural effusion.
