Background: Climate change profoundly shapes the population health at the global scale. However, there was still insufficient and inconsistent evidence for the association between heat exposure and chronic kidney disease (CKD).
Methods: In the present study, we studied the association of heat exposure with hospitalizations for cause-specific CKD using a national inpatient database in China during the study period of hot season from 2015 to 2018.
Objective: To describe the trend of tuberculosis (TB) diagnosis in the migrant city Shenzhen, China, and analyze the risk factors of diagnosis delays.
Methods: Demographic and clinical information of TB patients from 2011 to 2020 in Shenzhen were extracted. A bundle of measures to enhance TB diagnosis had been implemented since late 2017.
Objective: To explore the expression of the N-methyl-D-aspartate (NMDA) receptor in the rat model of orchialgia and its possible mechanisms.
Methods: According to Yoshioka's method, the male rats in the control group were injected with 0.2 ml saline, and those in the experimental group with 0.
Background: Long noncoding RNAs (lncRNAs) can regulate the expression of genes at almost every level. The altered expression of lncRNAs was observed in many kinds of cancers. Until recently, few studies have focused on the function of lncRNAs in the context of papillary thyroid carcinoma (PTC).

A total of 7385 consecutive thyroid cancer patients who underwent thyroidectomy were retrospectively reviewed. 4087 (55.

This study aimed to determine the ultrasonographic characteristics of papillary thyroid carcinoma. The ultrasonographic and pathological data of 2453 thyroid nodules in a cohort of 1895 Chinese patients who underwent thyroidectomy from January 2010 to December 2012 were retrospectively reviewed.

Objective: To analyze the clinic-pathologic features of elderly myocardial infarction patients (> 60 years) with and without left ventricular aneurysm formation.
Methods: Between January 1980 and October 2009, 107 myocardial infarction patients were divided into aneurysm group (n = 31) and non-aneurysm group (n = 76) according to autopsy results and the clinic-pathologic features of the two groups were compared.
Results: Previous angina pectoris history was significantly less in aneurysm group than in non-aneurysm group [45.
Objective: To investigate the validity of CT perfusion in assessing angiogenic activity of lung cancer.
Methods: Fifty-six patients with lung cancer scheduled for elective surgical resection received 16-slice helical CT perfusion imaging. Time-density curve (TDC), blood flow (BF), blood volume (BV), mean transmit time (MTT) and permeability surface area product (PS) were calculated.
Background: Rosai-Dorfman disease (RDD) in sellar/suprasellar region is a rare intracranial disorder. The diagnostic evaluation of this condition using magnetic resonance imaging (MRI) has seldom been described previously. The purpose of our study was to describe MRI characteristics of sellar/suprasellar region RDD.

Objective: To describe mortality, cause of death and life expectancy among Chinese (both immigrant and Canadian-born) and other Canadians in the Province of Alberta.
Methods: A Chinese surname list was applied to the Alberta Health Insurance Plan and Vital Statistics Birth registry databases to define the Chinese population, and to the Vital Statistics Death registry to determine deaths among Chinese in Alberta from 1995 to 2003. Age- and sex-specific mortality, cause of death and life expectancy were calculated.

Objective: To study the clinicopathologic features and radiologic findings of dysembryoplastic neuroepithelial tumor (DNT).
Methods: The clinical presentations, radiologic findings, histologic features and immunophenotype of 9 cases of DNT were analyzed.
Results: The age of patients ranged from 12 to 51 years (mean age = 32 years).

Background: Despite increasing advocacy for an "opt-out" strategy in routine prenatal HIV screening programs in Canada, no published studies have examined factors that may affect acceptance of prenatal HIV testing.
Methods: We included all pregnant women in Alberta who received prenatal care (N = 38,712) and their caregivers (N = 2,007) between January 1 and November 30, 2000. Factors associated with non-acceptance of HIV testing in both pregnant women and their caregivers were assessed using multivariate logistic regression.
The predominant etiologic theory of preeclampsia is that reduced uteroplacental perfusion is the unique pathogenic process in the development of preeclampsia. Decreased uteroplacental blood flow would result in lower birth weights. To date, no study has assessed the effect of preeclampsia on birth weight by gestational age.
